SENESCO TECHNOLOGIES, INC. AND SUBSIDIARY ----------------------------------------- (A DEVELOPMENT STAGE COMPANY) ----------------------------- NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ---------------------------------------------------- (unaudited) NOTE 1 - BASIS OF PRESENTATION: The financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-KSB for the year ended June 30, 2001. In the opinion of the Company's management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting solely of those which are of a normal recurring nature, necessary to present fairly its financial position as of December 31, 2001 and as of June 30, 2001, the results of its operations for the three month periods ended December 31, 2001 and 2000, the results of its operations and cash flows for the six month periods ended December 31, 2001 and 2000 and for the period from inception on July 1, 1998 through December 31, 2001. Interim results are not necessarily indicative of results for the full fiscal year. Senesco is a development stage functional genomics company whose mission is to enhance the quality and productivity of fruits, flowers, vegetables and agronomic crops through the control of senescence (aging) in plants. Results to date include longer shelf life of perishable produce, increased seed and biomass yield and greater tolerance to environmental stress. NOTE 2 - LOSS PER SHARE: Net loss per common share is computed by dividing the loss by the weighted average number of common shares outstanding during the period. Since September 7, 1999, the Company has had outstanding options and warrants to purchase its common stock, $0.01 par value per share (the "Common Stock"), however, shares to be issued upon the exercise of options and warrants are not included in the computation of diluted loss per share as the effect is anti-dilutive. -8-

SENESCO TECHNOLOGIES, INC. AND SUBSIDIARY ----------------------------------------- (A DEVELOPMENT STAGE COMPANY) ----------------------------- NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS ---------------------------------------------------- (unaudited) NOTE 3 - SIGNIFICANT EVENTS: Employment Agreement On October 4, 2001, the Company hired Bruce C. Galton as its new President and Chief Executive Officer. In conjunction with Mr. Galton's appointment, the Company entered into a three-year employment agreement with Mr. Galton, effective October 4, 2001. The agreement shall automatically renew for successive one-year terms thereafter, unless written notice of termination is provided at least 120 days prior to the end of the applicable term. The agreement provides Mr. Galton with an annual base salary of $200,000 plus certain benefits, including potential bonuses, equity awards and other perquisites as determined by the Board of Directors. The agreement also provides that Mr. Galton is entitled to a lump sum payment of 1.5 times his base annual salary if his employment with the Company is terminated without cause or with good reason (as defined within the agreement). If Mr. Galton's employment with the Company is terminated pursuant to a change in control (as defined within the agreement), he is entitled to receive the difference between the monies actually received upon termination and 1.5 times his annual base salary. Stock Incentive Plan, Option Grants and Additional Warrant Grants On October 4, 2001, the Board of Directors of the Company approved an amendment to the Company's 1998 Stock Incentive Plan, as amended (the "Plan"), to increase the maximum number of shares of Common Stock available for issuance under the Plan from 1,000,000 shares to 2,000,000 shares. Stockholder approval for the increase was obtained at the Company's Annual Meeting of Stockholders held on November 29, 2001. On October 4, 2001, the Board of Directors unanimously approved and the Company subsequently issued: (i) options under the Plan to purchase an aggregate of 1,116,000 shares of Common Stock with a weighted average exercise price of $2.38 per share; and (ii) warrants to purchase an aggregate of an additional 180,000 shares of Common Stock with a weighted average exercise price of $1.59 per share. The effective dates of the above grants were from October 2, 2001 through December 1, 2001. On December 1, 2001, the Company granted, pursuant to the Plan, to Ruedi Stalder, the Company's former Chief Executive Officer, options to purchase 65,000 shares of Common Stock with an exercise price of $2.05 per share. Such options were granted to Mr. Stalder in lieu of receiving cash compensation in the amount of $131,250 for services provided as an officer of the Company during the period from January 1, 2000 through September 30, 2001. -9-

SENESCO TECHNOLOGIES, INC.

New Jersey Economic Development Authority In November 2001, pursuant to the New Jersey Technology Tax Credit Transfer Program (the "Program"), the Company received approval from the New Jersey Economic Development Authority (the "EDA") to sell the Company's New Jersey net operating loss tax benefit in the amount of $174,325 for the fiscal year ended June 30, 2000.

An application must be submitted to the EDA by June 30, 2002. However, there can be no assurance that the Company will be approved to participate in the Program for the year ended June 30, 2001 or if approved, that the Company will be able to sell all or part of its New Jersey net operating loss tax benefit. Financings On November 30, 2001, the Company consummated a private placement (the "Stanford Private Placement") with Stanford Venture Capital Holdings, Inc. ("Stanford"), of 1,142,858 shares of Common Stock and warrants to purchase 1,000,000 shares of Common Stock for the aggregate cash consideration of $2,000,000. Costs associated with the Stanford Private Placement totaled $256,347. The Company did not engage a placement agent for the sale of such securities. Fifty percent (50%) of the warrants were issued with an exercise price equal to $2.00 per share and fifty percent (50%) of the warrants were issued with an exercise price equal to $3.25 per share, with all such warrants vesting on the date of grant. Pursuant to the Securities Purchase Agreement, the purchase price of one unit, which consisted of one share of Common Stock and a warrant to purchase 0.875 shares of Common Stock, was equal to $1.75 per unit. In addition, the Company entered into a Registration Rights Agreement with Stanford. The Registration Rights Agreement provides, among other things, that a shelf registration statement be filed on or before June 30, 2002, as well as piggy-back registration rights for a three-year period from the date of the agreement. -10-

Costs associated with these transactions totaled $158,175. The Company did not engage a placement agent for the sale of such securities. In addition, the Company entered into Registration Rights Agreements with these purchasers. The Registration Rights Agreements provide for, among other things, piggy-back registration rights for a three-year period from the date of each agreement. In connection with the above private placements, on December 26, 2001, the Board of Directors unanimously approved the issuance of warrants to certain entities to purchase an additional 500,000 shares of Common Stock on the same terms and conditions as the warrants issued in the Accredited Investor Private Placement. NOTE 4 - SUBSEQUENT EVENT: In January 2002, the Company consummated another private placement with Stanford for 571,429 shares of Common Stock and warrants to purchase 500,000 shares of Common Stock for the aggregate cash consideration of $1,000,000, on the same terms and conditions as the initial Stanford Private Placement. Costs associated with this transaction approximated $140,000. -11-

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND PLAN OF OPERATION. OVERVIEW Business of the Company The primary business of Senesco Technologies, Inc., a Delaware corporation (the "Company"), and its wholly-owned subsidiary, Senesco, Inc., a New Jersey corporation ("Senesco"), is the research, development and commercial exploitation of a potentially significant platform technology involving the identification and characterization of genes that the Company believes control the aging of plant cells (senescence) and may also control the programmed cell death of mammalian cells (apoptosis). The Company's technology goals for plant applications are to: (i) extend the shelf-life of perishable plant products; (ii) produce larger and more leafy crops; (iii) increase crop production (yield) in horticultural and agronomic crops; and (iv) reduce the harmful effects of environmental stress. Senescence in plant tissues is the natural aging of these tissues. Loss of cellular membrane integrity is an early event during the senescence of all plant tissues that prompts the deterioration of fresh flowers, fruits and vegetables. This loss of integrity, which is attributable to the formation of lipid metabolites in membrane bilayers that "phase-separate," causes the membranes to become "leaky." A decline in cell function ensues, leading to deterioration and eventual death (spoilage) of the tissue. A delay in senescence increases shelf-life and extends the plant's growth timeframe, which allows the plant to devote more time to the photosynthetic process. The Company has shown that the additional energy gained in this period leads directly to increased seed production, and therefore increases crop yield. Seed production is a vital agricultural function. For example, oil-bearing crops store oil in their seeds. The Company has also shown that delaying senescence allows the plant to allocate more energy toward growth, leading to larger plants (increased biomass) and more leafy crops. Most recently, the Company has demonstrated that delaying senescence results in crops which exhibit increased resilience to water deprivation. Drought resistant crops may ultimately be more cost effective due to reduced loss in the field and less time spent on crop management. The technology presently utilized by the industry for increasing the shelf-life in certain flowers, fruits and vegetables relies on reducing ethylene biosynthesis, and hence only has application to a limited number of plants that are ethylene-sensitive. The Company's technology is novel in that its research and development focuses on the discovery and development of new gene technologies, which are designed to confer positive traits on fruits, flowers, vegetables, forestry species and agronomic crops. To date, the Company has isolated and characterized the senescence-induced lipase gene, deoxyhypusine synthase ("DHS") gene and Factor 5A gene in certain species of plants. The Company's goal is to inhibit the expression of (or silence) these genes to delay senescence, which will in turn extend shelf-life, increase biomass, increase yield and increase resistance to environmental stress, thereby demonstrating "proof of concept" in each category of crop. In addition to the Harris Moran License Agreement (as defined below), the Company plans to license this technology to additional strategic partners and/or enter into joint ventures. -12-

The Company is currently working with lettuce, melon, tomato, canola, Arabidopsis (a model plant which produces oil in a manner similar to canola) and banana plants, and has obtained "proof of concept" for the lipase and DHS genes in several of these plants. Near-term research and development initiatives include: (i) silencing the Factor 5A gene in these six types of plants; and (ii) further propagation of transformed plants with the Company's silenced genes. Additionally, the Company has isolated the DHS and Factor 5A genes in mammalian tissue. The Company has also completed its research and development initiative in carnation flower, which yielded a one hundred percent (100%) increase in shelf-life through the inhibition of the DHS reaction. Subsequent initiatives include: (i) expanding the lipase, DHS and Factor 5A gene technology into a variety of other commercially viable agricultural crops such as lettuce and melon; (ii) developing transformed plants that possess new beneficial traits such as increased tolerance to disease and environmental stress; and (iii) assessing the function of the DHS and Factor 5A genes in mammalian tissue through the accumulation of additional experimental data. The Company's strategy focuses on various plants to allow flexibility that will accommodate different plant reproduction strategies among the various sectors of the broad agricultural and horticultural markets. There can be no assurance, however, that the Company's research and development efforts will be successful, or if successful, that the Company will be able to commercially exploit its technology. The Company's research and development is performed by third party researchers at the direction of the Company pursuant to various research and license agreements. The primary research and development effort takes place at the University of Waterloo in Ontario, Canada, where the technology was developed. Additional research and development is performed in connection with the Harris Moran License Agreement as well as through the Company's Joint Venture (as defined below) with Rahan Meristem Ltd. in Israel. Agricultural Target Markets The Company's technology embraces crops that are reproduced both through seeds and propagation, which are the only two means of commercial crop reproduction. Propagation is a process whereby the plant does not produce fertile seeds and must reproduce through cuttings from the parent plant which are planted and become new plants. In order to address the complexities associated with marketing and distribution in the worldwide produce market, the Company has adopted a multi-faceted commercialization strategy, in which it plans to enter into licensing agreements or other strategic relationships with a variety of companies on a crop-by-crop basis. In November 2001, the Company entered into a worldwide exclusive license with Harris Moran Seed Company (the "Harris Moran License Agreement" or "License") to commercialize the Company's technology in lettuce and certain melons. In connection with the License, the Company received an initial license fee of $125,000 in November 2001. Upon the completion of certain marketing and development benchmarks set forth in the License, the Company will receive a total of $4,000,000 in development payments over a multi-year period along with royalties upon commercial introduction. -13-

Agricultural Marketing Based upon the Company's multi-faceted commercialization strategy, it anticipates that there may be a significant period of time before plants enhanced using its technology reach consumers. Thus, the Company has not begun to actively market its technology directly to consumers, but rather, it has sought to establish itself within the industry through its advertising program in trade journals, newspapers, a national magazine, as well as through direct communication with prospective licensees. Joint Venture On May 14, 1999, the Company entered into a joint venture agreement with Rahan Meristem Ltd., an Israeli company ("Rahan"), engaged in the worldwide export marketing of banana germ-plasma (the "Joint Venture"). Rahan accounts for approximately ten percent (10%) of the worldwide export of banana seedlings. The Company has contributed, by way of a limited, exclusive, world-wide license to the Joint Venture, access to its technology, discoveries, inventions and know-how (patentable or otherwise), pertaining to plant genes and their cognate expressed proteins that are induced during senescence (plant aging) for the purpose of developing, on a joint basis, genetically enhanced banana plants which will result in a "longer shelf-life" banana. Rahan has contributed its technology, inventions and know-how with respect to banana plants. The Joint Venture is equally owned by each of the parties. There can be no assurance, however, that the Joint Venture will be successful, or if successful, that the Company will be able to commercially exploit its technology. The Joint Venture applied for and received a conditional grant that totals approximately $340,000, which constitutes fifty percent (50%) of the Joint Venture's research and development budget over a four year period, from the Israel - U.S. Binational Research and Development (the "BIRD") Foundation (the "BIRD Grant"). Such grant, along with certain royalty payments, shall only be repaid to the BIRD Foundation upon the commercial success of the Joint Venture's technology. The commercial success is measured based upon certain benchmarks and/or milestones achieved by the Joint Venture. These benchmarks are reported periodically to the BIRD Foundation by the Joint Venture. As of December 31, 2001, Senesco has directly received a total of $56,858, $11,051 of which was received during the current quarter, from the BIRD Foundation for research and development expenses the Company has incurred which are associated with the research and development efforts of the Joint Venture. The Company expects to receive additional installments of the BIRD Grant as its expenditures associated with the Joint Venture increase above certain levels. As of December 31, 2001, the Company's portion of the Joint Venture's aggregate expenses totaled approximately $182,000, $11,500 of which was incurred during the current quarter. All aspects of the Joint Venture's research and development initiative are proceeding on time, or are ahead of the original schedule laid out at the inception of the Joint Venture. Both the DHS and lipase genes have been identified and isolated in banana, and the Joint Venture is currently in the process of silencing these genes. Once silenced, the goal is to transform banana plants, thereby yielding fruit with extended shelf-life and plants which are more tolerant to disease and environmental stress. -14-

Consistent with the Company's commercialization strategy, it intends to attract other companies interested in strategic partnerships or licensing its technology. The Harris Moran License Agreement and the Joint Venture with Rahan are steps toward the execution of its strategy. The Company also plans to enter into joint ventures with companies having well-established channels of distribution and, in such cases, the Company will have more direct control over commercialization activities. However, there can be no assurance that the Company will be able to successfully implement its commercialization strategy. INTELLECTUAL PROPERTY Research and Development The inventor of the Company's technology, John E. Thompson, Ph.D., is the Associate Vice President, Research and former Dean of Science at the University of Waterloo in Ontario, Canada, and is the Executive Vice President of Research and Development of the Company. Dr. Thompson is also a director and stockholder of the Company and owns 5.7% of the outstanding shares of the Company's common stock, $0.01 par value (the "Common Stock") as of December 31, 2001. Senesco entered into a three-year research and development agreement, dated as of September 1, 1998 (the "Research and Development Agreement"), with the University of Waterloo and Dr. Thompson as the principal inventor. The Research and Development Agreement provides that the University of Waterloo will perform research and development under the direction of Senesco, and Senesco will pay for the cost of this work and make certain payments totaling approximately CDN $1,250,000 (as specified therein), which represented approximately US $835,000 on December 31, 2001. In return for these payments, the Company has all rights to the intellectual property derived from the research. Effective September 1, 2001, the Company extended the Research and Development Agreement for an additional one-year period in the amount of CDN $433,700. As of December 31, 2001, such amount represented approximately US $272,000. During the three month periods ended December 31, 2001 and December 31, 2000, the Company has spent approximately $67,022 and $89,948, respectively, in connection with the Research and Development Agreement. During the six month periods ended December 31, 2001 and December 31, 2000, the Company has spent approximately $114,160 and $167,743, respectively, in connection with the Research and Development Agreement. Effective May 1, 1999, the Company entered into a consulting agreement for research and development with Dr. Thompson. On July 1, 2001, the Company and Dr. Thompson renewed the consulting agreement for an additional three-year term as provided for under the terms and conditions of the agreement. This agreement provides for monthly payments of $3,000 to Dr. Thompson through June 2004. The agreement shall automatically renew for an additional three-year term, unless either of the parties provides the other with written notice within six months of the end of the term. The Company's future research and development program focuses on the discovery and development of new gene technologies which aim to extend shelf-life and to confer other positive traits on fruits, flowers, vegetables and agronomic row crops and on the commencement of additional mammalian cell research. Over the next twelve months, the Company plans the following research and development initiatives: (i) the development of transformed plants that possess new beneficial traits, such as protection against drought and disease, with emphasis on -15-

lettuce, melon, corn, forestry products and the other species noted in (ii) through (v); (ii) the development of enhanced banana plants through the Joint Venture with Rahan; (iii) the development of enhanced lettuce and melon plants through the Harris Moran License Agreement; (iv) the isolation of new genes in the Arabidopsis, tomato, lettuce, soybean, rape seed (canola) and melon plants, among others, at the University of Waterloo; and (v) assessing the function of the DHS and Factor 5A genes in mammalian tissue. The Company may further expand its research and development initiative beyond the initiatives listed above. Patent Applications Dr. Thompson and his colleagues, Dr. Yuwen Hong and Dr. Katalin Hudak, filed a patent application on June 26, 1998 (the "Original Patent Application") to protect their invention, which is directed to methods for controlling senescence in plants. By assignment dated June 25, 1998 and recorded with the United States Patent and Trademark Office (the "PTO"), on June 26, 1998, Drs. Thompson, Hong and Hudak assigned all of their rights in and to the Original Patent Application and any other applications filed in the United States or elsewhere with respect to the invention and/or improvements thereto to Senesco, L.L.C. Senesco succeeded to the assignment and ownership of the Original Patent Application. Drs. Thompson, Hong and Hudak filed an amendment to the Original Patent Application on February 16, 1999 (the "Amended Patent Application" and together with the Original Patent Application, the "First Patent Application") titled "DNA Encoding A Plant Lipase, Transgenic Plants and a Method for Controlling Senescence in Plants." The Amended Patent Application serves as a continuation of the Original Patent Application. Concurrent with the filing of the Amended Patent Application with the PTO and as in the case of the Original Patent Application, Drs. Thompson, Hong and Hudak assigned all of their rights in and to the Amended Patent Application and any other applications filed in the United States or elsewhere with respect to such invention and/or improvements thereto to Senesco. Drs. Thompson, Hong and Hudak have received shares of restricted Common Stock of the Company in consideration for the assignment of the First Patent Application. The inventions, which were the subject of the First Patent Application, include a method for controlling senescence of plants, a vector containing a cDNA whose expression regulates senescence, and a transformed microorganism expressing the lipase of the cDNA. Management believes that the inventions provide a means for delaying deterioration and spoilage, which could greatly increase the shelf-life of fruits, vegetables, and flowers by silencing or substantially repressing the expression of the lipase gene induced coincident with the onset of senescence. The Company filed a second patent application (the "Second Patent Application," and together with the First Patent Application, collectively, the "Patent Applications") on July 6, 1999, titled "DNA Encoding A Plant Deoxyhypusine Synthase, Transgenic Plants and a Method for Controlling Programmed Cell Death in Plants." The inventors named on the patent are Drs. John E. Thompson, Tzann-Wei Wang and Dongen Lily Lu. Concurrent with the filing of the Second Patent Application with the PTO and as in the case of the First Patent Application, Drs. Thompson, Wang and Lu assigned all of their rights in and to the Second Patent Application and any other applications filed in the United States or elsewhere with respect to such invention and/or improvements thereto to Senesco. Drs. Thompson, Wang and Lu have received options to purchase Common Stock of the Company in consideration for the assignments of the Second Patent Application. The inventions include a method for the genetic modification of plants to -16-

control the onset of either age-related or stress-induced senescence, an isolated DNA molecule encoding a senescence induced gene, and an isolated protein encoded by the DNA molecule. The Company has broadened the scope of its intellectual property protection by utilizing the Patent Cooperation Treaty ("PCT") to facilitate international filing and prosecution of the Patent Applications. The First Patent Application was published through the PCT in August 2000, and then between August 2001 and October 2001 was filed in Australia, Canada, China, Japan, Korea, New Zealand and Europe through the European Patent Office, which has twenty member states. Israel is the last remaining country in which the Company opted to file that has yet to issue a filing date. The Second Patent Application was published by the PCT in January 2001. The Company is in the process of drafting various patent applications for new aspects of the Company's senescence technology. The Company has filed several new Continuations in Part ("CIPs") on both the First Patent Application and the Second Patent Application to ensure, on an ongoing basis, that its intellectual property pertaining to new technological developments is appropriately protected. There can be no assurance that patent protection will be granted with respect to all the foregoing Patent Applications, or any other applications, or that, if granted, the validity of such patents will not be challenged. Furthermore, there can be no assurance that claims of infringement upon the proprietary rights of others will not be made, or if made, could be successfully defended against. Agricultural Market Competition and Industry Trends The Company's competitors in the agricultural industry are primarily focused on research and development rather than commercialization. Those competitors which are presently attempting to distribute their technology have generally utilized one of the following commercialization distribution channels: (i) licensing technology to major marketing and distribution partners; (ii) distributing seedlings directly to growers; or (iii) entering into strategic alliances. In addition, some competitors are owned by established produce distribution companies, which alleviates the need for strategic alliances, while others are attempting to create their own distribution and marketing channels. The Company's competitors in the field of delaying plant senescence are companies that develop and produce transformed plants in which ethylene biosynthesis has been silenced. Such companies include, among others: Paradigm Genetics; Aventis Crop Science; Mendel Biotechnology; Bionova Holding Corporation; Renessen LLC; Exelixis Plant Sciences, Inc.; and Eden Bioscience. The Company believes that its proprietary technology is unique and, therefore, places it at a competitive advantage in the industry. However, there can be no assurance that the Company's competitors will not develop a similar product with properties superior to its own or at greater cost-effectiveness. -17-

Government Regulation At present, the U.S. federal government regulation of biotechnology is divided among three agencies: (i) the U.S. Department of Agriculture regulates the import, field-testing and interstate movement of specific types of genetic engineering that may be used in the creation of transformed plants; (ii) the Environmental Protection Agency regulates activity related to the invention of plant pesticides and herbicides, which may include certain kinds of transformed plants; and (iii) the Food and Drug Administration (the "FDA") regulates foods derived from new plant varieties. The FDA requires that transformed plants meet the same standards for safety that are required for all other plants and foods in general. Except in the case of additives that significantly alter a food's structure, the FDA does not require any additional standards or specific approval for genetically engineered foods but expects transformed plant developers to consult the FDA before introducing a new food into the market place. The Company believes that its current activities, which to date have been confined to research and development efforts, do not require licensing or approval by any governmental regulatory agency. The Company may be required, however, to obtain such licensing or approval from governmental regulatory agencies prior to the commercialization of its transformed plants. There can be no assurance that such licensing or approval by any governmental regulatory agency will be obtained in a timely manner, if at all. In addition, government regulations are subject to change and, in such event, the Company may be subject to additional regulations or require such licensing or approval in the future. Employees In addition to the scientists performing funded research for the Company at the University of Waterloo, as of December 31, 2001, the Company had five employees and one consultant, four of whom were executive officers and were involved in the management of the Company. The officers are assisted by a Scientific Advisory Board that consisted consisted of three prominent experts in the field of transformed plants. Alan Bennett, Ph.D., is the Executive Director of the Office of Technology Transfer at the University of California. His research interests include: the molecular biology of tomato fruit development and ripening; the molecular basis of membrane transport; and cell wall disassembly. A. Carl Leopold, Ph.D., and William R. Woodson, Ph.D. were the other members of the Scientific Advisory Board. The Company is recruiting scientists with a broader field of expertise than had previously existed on the Scientific Advisory Board. In connection with this recruitment effort, Drs. Leopold and Woodson stepped down from the Scientific Advisory Board on October 31, 2001. Dr. Bennett continues to serve as Chairman of the Scientific Advisory Board. In connection with the expanding scope of the Company's research and development program, Charles A. Dinarello, M.D. joined the Scientific Advisory Board in February 2002. Dr. Dinarello is a Professor of Medicine at the University of Colorado School of Medicine, a member of the U.S. National Academy of Sciences and the author of over 500 published research articles. In addition to his active academic research career, Dr. Dinarello has held advisory positions with two branches of the National Institutes of Health and positions on the Board of Governors of both the Weizmann Institute and Ben Gurion University. -18-

In addition to his service on the Scientific Advisory Board, the Company utilizes Dr. Bennett as a consultant experienced in plant transformation. Effective November 1, 2001, the Company entered into a one-year consulting agreement with Dr. Bennett, which provides for monthly payments of $2,400 to Dr. Bennett through October 31, 2002. Furthermore, pursuant to the Research and Development Agreement, the majority of the Company's research and development activities are conducted at the University of Waterloo under the supervision of Dr. Thompson. The Company utilizes the University's substantial research staff including graduate and post-graduate researchers. The Company may hire additional employees over the next twelve months to meet needs created by possible expansion of its marketing activities and product development.

LIQUIDITY AND CAPITAL RESOURCES Overview As of December 31, 2001, the Company's cash balance was $2,816,428, and the Company had working capital of $2,386,764. As of December 31, 2001, the Company had a federal tax loss carry-forward of approximately $4,965,000 and a state tax loss carry-forward of approximately $2,525,000 to offset future taxable income. There can be no assurance, however, that the Company will be able to take advantage of any or all of such tax loss carry-forwards, if at all, in future fiscal years. Financing Needs To date, the Company has not generated any significant revenues. The Company has not been profitable since inception, will incur additional operating losses in the future, and may require additional financing to continue the development and subsequent commercialization of its technology. While the Company does not expect to generate significant revenues in the near future, the Company may enter into additional licensing or other agreements with marketing and distribution partners that may result in license fees, revenues from contract research, or other related revenue. The Company expects its capital requirements to increase significantly over the next several years as it commences new research and development efforts, undertakes new product developments, increases marketing and administration infrastructure and embarks on developing in-house business capabilities and facilities. The Company's future liquidity and capital funding requirements will depend on numerous factors, including, but not limited to, the levels and costs of the Company's research and development initiatives and the cost and timing of the expansion of the Company's marketing efforts. BIRD Grant In October 2001, the Company received $11,051 from the BIRD Foundation for research and development expenses that the Company has incurred in connection with the Joint Venture. The Company anticipates receiving additional funds from the BIRD Grant in the future to assist in funding its Joint Venture. License Agreement In November 2001, the Company entered into a worldwide exclusive licensing agreement with Harris Moran Seed Company to commercialize the Company's technology in lettuce and certain melons. In connection with the License, the Company received an initial license fee of $125,000 in November 2001. Upon the completion of certain marketing and development benchmarks as set forth in the License, the Company will receive a total of $4,000,000 in development payments over a multi-year period along with royalties upon commercial introduction. -20-

New Jersey Economic Development Authority In November 2001, pursuant to the New Jersey Technology Tax Credit Transfer Program (the "Program"), the Company received approval from the New Jersey Economic Development Authority (the "EDA") to sell the Company's New Jersey net operating loss tax benefit in the amount of $174,325 for the fiscal year ended June 30, 2000. In December 2001, the Company sold its entire New Jersey net operating loss tax benefit and received net proceeds of $150,551. The Company may apply to participate in the Program to sell its New Jersey net operating loss tax benefit in the amount of approximately $151,000 for the fiscal year ended June 30, 2001. An application must be submitted to the EDA by June 30, 2002. However, there can be no assurance that the Company will be approved to participate in the Program for the year ended June 30, 2001 or if approved, that the Company will be able to sell all or part of its New Jersey net operating loss tax benefit. Financings On November 30, 2001, the Company consummated a private placement (the "Stanford Private Placement") with Stanford Venture Capital Holdings, Inc. ("Stanford"), of 1,142,858 shares of Common Stock and warrants to purchase 1,000,000 shares of Common Stock for the aggregate cash consideration of $2,000,000. Costs associated with the Stanford Private Placement totaled $256,347. Pursuant to the Securities Purchase Agreement, the purchase price of one unit, which consisted of one share of Common Stock and a warrant to purchase 0.875 shares of Common Stock, was equal to $1.75 per unit. On December 1, 2001, the Company granted, pursuant to the Plan, to Ruedi Stalder, the Company's former Chief Executive Officer, options to purchase 65,000 shares of Common Stock with an exercise price of $2.05 per share. Such options were granted to Mr. Stalder in lieu of receiving cash compensation in the amount of $131,250 for services provided as an officer of the Company during the period from January 1, 2000 through September 30, 2001. During the period from July 10, 2001 through November 5, 2001, the Company issued six unsecured bridge notes (the "Notes") payable to certain directors of the Company in the aggregate principal amount of $525,000. The Notes had an annual interest rate equal to the prime rate on the date that the Notes were issued (5.50% to 6.75%) and such interest was payable upon maturity of the Notes. The Notes and accrued interest were due on January 15, 2002. On December 3, 2001, the directors converted the Notes and accrued interest in the aggregate amount of $534,316 into 305,323 shares of Common Stock and warrants to purchase 267,158 shares of Common Stock on the same terms and conditions as the Stanford Private Placement. Also, in November 2001, the Company initiated a private placement (the "Accredited Investor Private Placement") to certain accredited investors for a minimum aggregate investment of $1,000,000 and a maximum aggregate investment of $3,000,000. The private placement offered units of one share of Common Stock and a warrant to purchase 0.4375 shares of Common Stock at a price equal to $1.75 per unit. On December 26, 2001, the Company entered into Securities Purchase Agreements for the aggregate amount of 665,714 shares of Common Stock and warrants to purchase 291,250 shares of Common Stock for the aggregate cash consideration of $1,165,000. Costs associated with these transactions totaled $158,175. -21-

In January 2002, the Company consummated another private placement with Stanford for 571,429 shares of Common Stock and warrants to purchase 500,000 shares of Common Stock for the aggregate cash consideration of $1,000,000, on the same terms and conditions as the initial Stanford Private Placement. Costs associated with this transaction approximated $140,000. Pursuant to the Securities Purchase Agreement, the purchase price of one unit, which consisted of one share of Common Stock and a warrant to purchase 0.875 shares of Common Stock, was equal to $1.75 per unit. The Company believes it has sufficient cash on hand to support its operating plan for at least the next twelve months. To enable the Company to fund its research and development and commercialization efforts, during November 2001 through January 2002, the Company issued an aggregate of 2,380,000 shares of Common Stock and warrants to purchase 1,791,250 of Common Stock for aggregate gross proceeds in the amount of $4,165,000, through several private placements. Additionally, Notes in the aggregate amount of $534,316, payable to certain directors of the Company, were converted into 305,323 shares of Common Stock and warrants to purchase 267,158 shares of Common Stock. RESULTS OF OPERATIONS Three Months Ended December 31, 2001 and Three Months Ended December 31, 2000 - ----------------------------------------------------------------------------- The Company is a development stage company. From its inception of operations on July 1, 1998 through September 30, 2001, the Company had no revenues. For the three months ended December 31, 2001, the Company had total revenue of $125,000. Revenue for the three month period ended December 31, 2001 consisted of the initial license fee in connection with the Harris Moran License Agreement. Operating expenses in each of the three month periods ended December 31, 2001 and December 31, 2000 were comprised of general and administrative expenses, research and development expenses and non-cash advertising, consulting and professional costs. Operating expenses for the three month periods ended December 31, 2001 and December 31, 2000 were $876,422 and $578,957, respectively, an increase of $297,465, or 51.4%. General and administrative expenses in each of the three month periods ended December 31, 2001 and December 31, 2000 consisted primarily of professional salaries and benefits, professional and consulting services, recruiting fees, office rent and investor relations expenses. General and administrative expenses for the three month periods ended December 31, 2001 and December 31, 2000 were $395,409 and $407,893, respectively. The decrease during the three month period ended December 31, 2001 of $12,484, or 3.1%, from the corresponding three month period ended December 31, 2000, resulted primarily from decreases in consulting fees, payroll, accounting fees and office rent, which were partially offset by increases in legal fees, recruiting fees and investor relations expenses. Research and development expenses in each of the three month periods ended December 31, 2001 and December 31, 2000 consisted primarily of professional salaries and benefits, fees associated with the Research and Development Agreement, direct expenses charged to research and development projects and allocated overhead charged to research and development projects. -22-

The decrease during the three month period ended December 31, 2001 of $36,893, or 28.2%, from the corresponding three month period ended December 31, 2000, resulted primarily from a reconciling adjustment for the period from June 1, 2000 through August 31, 2001 in connection with the Research and Development Agreement with the University of Waterloo, a reduction in the amount of research fees paid in connection with the carnation project, which was completed during the year ended June 30, 2001, and a reduction in the amount of fees incurred for the Scientific Advisory Board. Non-cash charges for options and warrants issued in exchange for services for the three month periods ended December 31, 2001 and December 31, 2000 were $387,192 and $40,350, respectively. Such costs consisted primarily of non-employee stock options and warrants granted as consideration for certain advertising, consulting and professional services. The increase during the three month period ended December 31, 2001 of $346,842, or 859.6%, from the corresponding three month period ended December 31, 2000, resulted primarily from the issuance of options and warrants and the vesting of previously issued options and warrants for advertising, consulting and professional services from October 1, 2001 through December 31, 2001.

The decrease during the six month period ended December 31, 2001 of $66,199, or 8.9%, from the corresponding six month period ended December 31, 2000, resulted primarily from decreases in consulting fees, accounting fees and office rent, which were partially offset by an increase in legal and recruiting fees.

Period From Inception on July 1, 1998 through December 31, 2001 - --------------------------------------------------------------- The Company is a development stage company. From its inception of operations on July 1, 1998 through September 30, 2001, the Company had no revenues. For the quarter ended December 31, 2001, the Company had revenue of $125,000, which consisted of the initial license fee in connection with the Harris Moran License Agreement. The Company has incurred losses each year since inception and has an accumulated deficit of $6,596,943 at December 31, 2001. The Company expects to continue to incur losses over, approximately, the next two to three years from expenditures on research, product development, marketing and administrative activities. The Company does not expect to generate significant revenues in the near future, during which time the Company will engage in significant research and development efforts. In November 2001, the Company entered into the Harris Moran License Agreement to commercialize the Company's technology in lettuce and various melons. The License provides that, upon completion of certain marketing and development benchmarks, the Company will receive a total of $4,000,000 in development payments over a multi-year period along with royalty payments to the Company upon commercial introduction. Consistent with the Company's commercialization strategy, the Company intends to attract other companies interested in strategic partnerships or licensing the Company's technology that may result in license fees, revenues from contract research and other related revenues. There can be no assurance, however, that the Company will be successful in attracting other companies willing to form strategic partnerships or license its technology. Furthermore, no assurance can be given that the Company's research and development efforts will result in any commercially viable products, or that any licensing or other agreements with marketing and distribution partners will result in revenues sufficient to support the business. Successful future operations will depend on the Company's ability to transform its research and development activities into commercializable technology. -24-

As soon as practicable after the -------------------------- exercise of this Warrant in whole or in part, and in any event within 10 days thereafter, the Company, at its expense, will cause to be issued in the name of, and delivered to, the Registered Holder, or as the Registered Holder (upon payment by the Registered Holder of any applicable transfer taxes) may direct: (i) a certificate or certificates for the number of full Warrant Shares to which the Registered Holder shall be entitled upon such exercise, which shall include, if applicable, the rounding of any fraction up to the nearest whole number of shares of Common Stock pursuant to Section 3 hereof; and (ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of Warrant Shares equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of Warrant Shares for which this Warrant was so exercised. 2. Adjustments. ----------- (a) Adjustments to Purchase Price for Diluting Issues. ------------------------------------------------- (i) Special Definitions. For purposes of this Section 2, the -------------------- following definitions shall apply: (A) "Option" shall mean rights, options or warrants to ------ subscribe for, purchase or otherwise acquire Common Stock or Convertible Securities. (B) "Original Issue Date" shall mean the date on which this -------------------- Warrant was first issued (or, if this Warrant was issued upon partial exercise of, or in replacement of, another warrant of like tenor, then the date on which such original warrant was first issued). (C) "Convertible Securities" shall mean any evidences of ----------------------- indebtedness, shares or other securities directly or indirectly convertible into or exchangeable for Common Stock, but excluding Options. (D) "Additional Shares of Common Stock" shall mean all ------------------------------------ shares of Common Stock issued (or, pursuant to subsection 2(a)(iii) below, deemed to be issued) by the Company after the Original Issue Date, other than: (I) shares of Common Stock issued or issuable upon conversion or exchange of any Convertible Securities or exercise of any Options, outstanding on the Original Issue Date; (II) shares of Common Stock issued or issuable by reason of a dividend, stock split, split-up or other distribution on shares of Common Stock that is covered by subsection 2(b) or 2(c) below. -2-

(III) shares of Common Stock (or Options with respect thereto) issued or issuable to employees or directors of, or consultants to, the Company or any of its subsidiaries pursuant to a plan, agreement or arrangement approved by the Board. (ii) No Adjustment of Purchase Price. No adjustment to the ----------------------------------- Purchase Price shall be made as the result of the issuance of Additional Shares of Common Stock if the consideration per share (determined pursuant to subsection 2(a)(v)) for such Additional Share of Common Stock issued or deemed to be issued by the Company is equal to or greater than $1.75 per share, as adjusted for those events set forth in subsections 2(b) and 2(c) below. (iii) Issue of Securities Deemed Issue of Additional Shares of ----------------------------------------------------------- Common Stock. - ------------ (A) If the Company at any time or from time to time after the Original Issue Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which, upon exercise, conversion or exchange thereof, would entitle the holder thereof to receive shares of Common Stock which are specifically excepted from the definition of Additional Shares of Common Stock by subsection 2(a)(i)(D) above) or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares of Common Stock (as set forth in the instrument relating thereto without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common Stock issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date. (B) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Purchase Price pursuant to the terms of subsection 2(a)(iv) below, are revised (either automatically pursuant to the provisions contained therein or as a result of an amendment to such terms) to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Company upon such exercise, conversion or exchange, then, effective upon such increase or decrease becoming effective, the Purchase Price computed upon the original issue of such Option or Convertible Security (or upon the occurrence of a record date with respect thereto) shall be readjusted to such Purchase Price as would have obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security. Notwithstanding the foregoing, no adjustment pursuant to this clause (B) shall have the effect of increasing the Purchase Price to an amount which exceeds the lower of (i) the Purchase Price on the original adjustment date, or (ii) the Purchase Price that would have resulted from any issuances of Additional Shares of Common Stock between the original adjustment date and such readjustment date. (C) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which, upon exercise, conversion or exchange thereof, would entitle the holder thereof to receive shares of Common Stock which are -3-

specifically excepted from the definition of Additional Shares of Common Stock by subsection 2(a)(i)(D) above), the issuance of which did not result in an adjustment to the Purchase Price pursuant to the terms of subsection 2(a)(iv) below (either because the consideration per share (determined pursuant to subsection 2(a)(v) hereof) of the Additional Shares of Common Stock subject thereto was equal to or greater than the Purchase Price then in effect, or because such Option or Convertible Security was issued before the Original Issue Date), are revised after the Original Issue Date (either automatically pursuant to the provisions contained therein or as a result of an amendment to such terms) to provide for either (1) any increase or decrease in the number of shares of Common Stock issuable upon the exercise, conversion or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to the Company upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended, and the Additional Shares of Common Stock subject thereto (determined in the manner provided in subsection 2(a)(iii)(A) above) shall be deemed to have been issued effective upon such increase or decrease becoming effective. (D) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged (as applicable) Convertible Security which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Purchase Price pursuant to the terms of subsection 2(a)(iv) below, the Purchase Price shall be readjusted to such Purchase Price as would have obtained had such Option or Convertible Security never been issued. (E) No adjustment in the Purchase Price shall be made upon the issue of shares of Common Stock or Convertible Securities upon the exercise of Options or the issue of shares of Common Stock upon the conversion or exchange of Convertible Securities, provided that the Purchase Price has been previously adjusted pursuant to this Section. (iv) Adjustment of Purchase Price Upon Issuance of Additional ----------------------------------------------------------- Shares of Common Stock. In the event the Company shall at any time after the - ----------------------- Original Issue Date issue Additional Shares of Common Stock (including Additional Shares of Common Stock deemed to be issued pursuant to subsection 2(a)(iii)), without consideration or for a consideration per share less than $1.75 per share, as adjusted for those events set forth in subsections 2(b) and 2(c) below, then the Purchase Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Purchase Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issue plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Company for the total number of Additional Shares of Common Stock so issued would purchase at such Purchase Price; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such Additional Shares of Common Stock so issued; provided that, (i) for the purpose of this subsection 2(a)(iv), all shares of Common Stock issuable upon conversion or exchange of Convertible Securities outstanding immediately prior to such issue shall be deemed to be outstanding, and (ii) the number of shares of Common Stock deemed issuable upon conversion or exchange of such outstanding Convertible Securities shall be determined without giving effect to any adjustments to the conversion or exchange price or conversion or exchange rate of such Convertible Securities resulting from the issuance of Additional Shares of Common Stock that is the subject of this calculation. -4-

(v) Determination of Consideration. For purposes of this --------------------------------- subsection 2(a), the consideration received by the Company for the issue of any Additional Shares of Common Stock shall be computed as follows: (A) Cash and Property: Such consideration shall: ----------------- (I) insofar as it consists of cash, be computed at the aggregate of cash received by the Company; (II) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board; and (III) in the event Additional Shares of Common Stock are issued or deemed to be issued together with other shares or securities or other assets of the Company for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (I) and (II) above, as determined in good faith by the Board. (B) Options and Convertible Securities. The consideration ----------------------------------- per share received by the Company for Additional Shares of Common Stock deemed to have been issued pursuant to subsection 2(a)(iii), relating to Options and Convertible Securities, shall be determined by dividing (I) the sum of the total amount, if any, received or receivable by the Company as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to the Company upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities,the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by (II) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities or, in the case of Options for Convertible -5-

Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities. (vi) Multiple Closing Dates. In the event the Company shall issue ---------------------- on more than one date Additional Shares of Common Stock which are comprised of shares of the same series or class of Common Stock, and such issuance dates occur within a period of no more than 120 days, then, upon the final such issuance, the Purchase Price shall be readjusted to give effect to all such issuances as if they occurred on the date of the final such issuance (and without giving effect to any adjustments as a result of such prior issuances within such period). (b) Adjustment for Stock Splits and Combinations. If the Company shall -------------------------------------------- at any time, or from time to time, after the Original Issue Date effect a subdivision of the outstanding Common Stock, the Purchase Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the Original Issue Date combine or consolidate the outstanding shares of Common Stock, the Purchase Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination or consolidation becomes effective. (c) Adjustment for Certain Dividends and Distributions. In the event --------------------------------------------------- the Company at any time, or from time to time, after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Purchase Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Purchase Price then in effect by a fraction: (A) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (B) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution; provided, however, that if such record date shall have been fixed and such - -------- ------- dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Purchase Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Purchase Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions. (d) Adjustment in Number of Warrant Shares. When any adjustment is --------------------------------------- required to be made in the Purchase Price pursuant to subsections 2(a), 2(b) or 2(c), the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect -6-

immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. (e) Adjustments for Other Dividends and Distributions. In the event --------------------------------------------------- the Company at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Company (other than shares of Common Stock) or in cash or other property (other than regular cash dividends paid out of earnings or earned surplus, determined in accordance with generally accepted accounting principles), then and in each such event provision shall be made so that the Registered Holder shall receive upon exercise hereof, in addition to the number of shares of Common Stock issuable hereunder, the kind and amount of securities of the Company, cash or other property which the Registered Holder would have been entitled to receive had this Warrant been exercised on the date of such event and had the Registered Holder thereafter, during the period from the date of such event to and including the Exercise Date, retained any such securities receivable during such period, giving application to all adjustments called for during such period under this Section 2 with respect to the rights of the Registered Holder. (f) Adjustment for Reorganization, Reclassification or Similar Events. ----------------------------------------------------------------- If there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Common Stock is converted into or exchanged for securities, cash or other property (other than a transaction covered by subsections 2(b), 2(c) or 2(e)) (collectively, a "Reorganization"), then, following such Reorganization, the Registered Holder shall receive upon exercise hereof the kind and amount of securities, cash or other property which the Registered Holder would have been entitled to receive pursuant to such Reorganization if such exercise had taken place immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder, to the end that the provisions set forth in this Section 2 (including provisions with respect to changes in and other adjustments of the Purchase Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities, cash or other property thereafter deliverable upon the exercise of this Warrant. (g) Certificate as to Adjustments. Upon the occurrence of each ------------------------------- adjustment or readjustment of the Purchase Price pursuant to this Section 2, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Registered Holder a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property for which this Warrant shall be exercisable and the Purchase Price) and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, as promptly as reasonably practicable after the written request at any time of the Registered Holder (but in any event not later than 10 days thereafter), furnish or cause to be furnished to the Registered Holder a certificate setting forth; (i) such adjustments and readjustments; (ii) the Purchase Price then in effect; and (iii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the exercise of this Warrant. 3. Fractional Shares. The Company shall not be required upon the exercise ------------------ of this Warrant to issue any fractions of shares of Common Stock or fractional Warrants; provided, -------- -7-

however, that if the Registered Holder exercises this Warrant, any fractional - ------- shares of Common Stock shall be eliminated by rounding any fraction up to the nearest whole number of shares of Common Stock. The Registered Holder of this Warrant, by acceptance hereof, expressly waives his right to receive any fractional share of Common Stock or fractional Warrant upon exercise of this Warrant. 4. Investment Representations. The initial Registered Holder represents and -------------------------- warrants to the Company as follows: (a) Investment. It is acquiring the Warrant, and (if and when it ---------- exercises this Warrant) it will acquire the Warrant Shares, for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and the Registered Holder has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof; (b) Federal and State Compliance. The Registered Holder understands ---------------------------- that this Warrant and any Warrant Shares purchased upon its exercise are securities, the issuance of which requires compliance with federal and state securities law, including the Securities Act of 1933, as amended (the "Act"); (c) Accredited Investor.

The Registered Holder acknowledges and ---------------------- understands that the Warrant and Warrant Shares constitute restricted securities under the Act and must be held indefinitely unless subsequently registered under the Act or an exemption from such registration is available. 5. Transfers, etc. -------------- (a) This Warrant may be assigned by the Registered Holder to an "accredited investor," as defined in Rule 501(a) of the Act, upon the execution and delivery to the Company of the assignment form annexed hereto, subject to any restrictions imposed by applicable securities laws. (b) The Warrant Shares shall not be sold or transferred unless either (i) they first shall have been registered under the Act, or (ii) the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Act. Notwithstanding the foregoing, no registration or opinion of counsel shall be required for (i) a transfer by a Registered Holder which is an entity to a wholly owned subsidiary of such entity, a transfer by a Registered Holder which is a partnership to a partner of such partnership or a retired partner of such partnership or to the estate of any such partner or retired partner, or a transfer by a Registered -8-

Holder which is a limited liability company to a member of such limited liability company or a retired member or to the estate of any such member or retired member, provided that the transferee in each case agrees in writing to be subject to the terms of this Section 5, or (ii) a transfer made in accordance with Rule 144 under the Act. (c) Each certificate representing Warrant Shares shall bear a legend substantially in the following form: THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BEPLEDGED, HYPOTHECATED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER SUCH ACT OR AN OPINION OF COUNSEL TO THE ISSUER THAT REGISTRATION IS NOT REQUIRED UNDER THE ACT. The foregoing legend shall be removed from the certificates representing any Warrant Shares, at the request of the holder thereof, at such time as they become eligible for resale pursuant to Rule 144(k) under the Act. (d) The Company will maintain a register containing the name and address of the Registered Holder of this Warrant. The Registered Holder may change its address as shown on the warrant register by written notice to the Company requesting such change. 6. Registration Rights.

Impairment.

Subscription Rights for Shares of Common Stock or Other Securities. ------------------------------------------------------------------- In case the Company or an affiliate of the Company shall, at any time after the date hereof and prior to the exercise of the Warrant, in full, issue any rights to subscribe for shares of Common Stock or any other securities of the Company or of such affiliate to all of the holders of Common Stock, the holder of the unexercised Warrant shall be entitled, in addition to the shares of Common Stock or other securities receivable upon the exercise of the Warrant, to receive such rights at the time -9-

such rights are distributed to the other stockholders of the Company, but only to the extent of the number of shares of Common Stock, if any, for which the Warrant remains exercisable. 10. Notices of Record Date, etc. In the event: --------------------------- (a) the Company shall take a record of the holders of its Common Stock (or other stock or securities at the time deliverable upon the exercise of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right; or (b) of any capital reorganization of the Company, any reclassification of the Common Stock of the Company, any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving entity and its Common Stock is not converted into or exchanged for any other securities or property), or any transfer of all or substantially all of the assets of the Company; or (c) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, then, and in each such case, the Company will send or cause to be sent to the Registered Holder a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up. Such notice shall be sent at least 10 days prior to the record date or effective date for the event specified in such notice. 11. Reservation of Stock.

securities for a period of 180 days from the effective date of such registration statement, and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing underwriters at the time of such offering. 14.

to time, by surrendering this Warrant, with the purchase form appended hereto as
Exhibit  I duly  executed  by or on  behalf  of the  Registered  Holder,  at the
- ----------
principal  office  of the  Company,  or at such  other  office  or agency as the
Company may  designate,  accompanied  by payment in full, in lawful money of the
United States, of the Purchase Price payable in respect of the number of Warrant
Shares purchased upon such exercise.

          (c) Exercise  Date.  Each  exercise of this Warrant shall be deemed to
              --------------
have been  effected  immediately  prior to the close of  business  on the day on
which this  Warrant  shall have been  surrendered  to the Company as provided in
subsection 1(b) above (the "Exercise Date"). At such time, the person or persons
in whose name or names any  certificates  for Warrant  Shares  shall be issuable
upon such exercise as provided in subsection  1(d) below shall be deemed to have
become the holder or holders of record of the Warrant Shares represented by such
certificates.

          (d) Issuance  of  Certificates.  As soon  as  practicable  after  the
              --------------------------
exercise of this  Warrant in whole or in part,  and in any event  within 10 days
thereafter, the Company, at its


expense, will cause to be issued in the name of, and delivered to, the Registered Holder, or as the Registered Holder (upon payment by the Registered Holder of any applicable transfer taxes) may direct: (i) a certificate or certificates for the number of full Warrant Shares to which the Registered Holder shall be entitled upon such exercise, which shall include, if applicable, the rounding of any fraction up to the nearest whole number of shares of Common Stock pursuant to Section 3 hereof; and (ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of Warrant Shares equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of Warrant Shares for which this Warrant was so exercised. 2. Adjustments. ----------- (a) Adjustment for Stock Splits and Combinations. If the Company shall -------------------------------------------- at any time or from time to time after the date on which this Warrant was first issued (or, if this Warrant was issued upon partial exercise of, or in replacement of, another warrant of like tenor, then the date on which such original warrant was first issued) (either such date being referred to as the "Original Issue Date") effect a subdivision of the outstanding Common Stock, the Purchase Price then in effect immediately before that subdivision shall be proportionately decreased. If the Company shall at any time or from time to time after the Original Issue Date combine the outstanding shares of Common Stock, the Purchase Price then in effect immediately before the combination shall be proportionately increased. Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective. (b) Adjustment for Certain Dividends and Distributions. In the event --------------------------------------------------- the Company at any time, or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Purchase Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Purchase Price then in effect by a fraction: (1) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (2) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution; provided, however, that if such record date shall have been fixed and such - -------- ------- dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Purchase Price shall -2-

be recomputed accordingly as of the close of business on such record date and thereafter the Purchase Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions. (c) Adjustment in Number of Warrant Shares. When any adjustment is --------------------------------------- required to be made in the Purchase Price pursuant to subsections 2(a) or 2(b), the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. (d) Adjustments for Other Dividends and Distributions. In the event --------------------------------------------------- the Company at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Company (other than shares of Common Stock) or in cash or other property (other than regular cash dividends paid out of earnings or earned surplus, determined in accordance with generally accepted accounting principles), then and in each such event provision shall be made so that the Registered Holder shall receive upon exercise hereof, in addition to the number of shares of Common Stock issuable hereunder, the kind and amount of securities of the Company, cash or other property which the Registered Holder would have been entitled to receive had this Warrant been exercised on the date of such event and had the Registered Holder thereafter, during the period from the date of such event to and including the Exercise Date, retained any such securities receivable during such period, giving application to all adjustments called for during such period under this Section 2 with respect to the rights of the Registered Holder. (e) Adjustment for Reorganization. If there shall occur any -------------------------------- reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Common Stock is converted into or exchanged for securities, cash or other property (other than a transaction covered by subsections 2(a), 2(b) or 2(d)) (collectively, a "Reorganization"), then, following such Reorganization, the Registered Holder shall receive upon exercise hereof the kind and amount of securities, cash or other property which the Registered Holder would have been entitled to receive pursuant to such Reorganization if such exercise had taken place immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder, to the end that the provisions set forth in this Section 2 (including provisions with respect to changes in and other adjustments of the Purchase Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities, cash or other property thereafter deliverable upon the exercise of this Warrant. (f) Certificate as to Adjustments. Upon the occurrence of each ------------------------------- adjustment or readjustment of the Purchase Price pursuant to this Section 2, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Registered Holder a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property for which this Warrant shall be exercisable and the Purchase Price) and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, as promptly as reasonably practicable after the written request at -3-

any time of the Registered Holder (but in any event not later than 10 days thereafter), furnish or cause to be furnished to the Registered Holder a certificate setting forth (i) the Purchase Price then in effect and (ii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the exercise of this Warrant. 3. Fractional Shares. The Company shall not be required upon the exercise ------------------ of this Warrant to issue any fractions of shares of Common Stock or fractional Warrants; provided, however, -------- ------- that if the Registered Holder exercises this Warrant, any fractional shares of Common Stock shall be eliminated by rounding any fraction up to the nearest whole number of shares of Common Stock. The Registered Holder of this Warrant, by acceptance hereof, expressly waives his right to receive any fractional share of Common Stock or fractional Warrant upon exercise of this Warrant. 4. Investment Representations. The initial Registered Holder represents and ---------------------------- warrants to the Company as follows: (a) Investment. It is acquiring the Warrant, and (if and when it ---------- exercises this Warrant) it will acquire the Warrant Shares, for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and the Registered Holder has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof; (b) Federal and State Compliance. The Registered Holder understands ------------------------------ that this Warrant and any Warrant Shares purchased upon its exercise are securities, the issuance of which requires compliance with federal and state securities law, including the Securities Act of 1933, as amended (the "Act"); (c) Accredited Investor.

The Registered Holder acknowledges and ---------------------- understands that the Warrant and Warrant Shares constitute restricted securities under the Act and must be held indefinitely unless subsequently registered under the Act or an exemption from such registration is available. 5. Transfers, etc. -------------- (a) This Warrant may not be transferred in any manner other than by will or by the laws of descent or distribution and may be exercised during the lifetime of the Registered Holder only by the Registered Holder. The terms of this Warrant shall be binding upon the executors, administrators, heirs, successor and assigns of the Registered Holder. -4-

(b) The Warrant Shares shall not be sold or transferred unless either (i) they first shall have been registered under the Act, or (ii) the Company first shall have been furnished with an opinion of legal counsel, reasonably satisfactory to the Company, to the effect that such sale or transfer is exempt from the registration requirements of the Act. Notwithstanding the foregoing, no registration or opinion of counsel shall be required for (i) a transfer by a Registered Holder which is an entity to a wholly owned subsidiary of such entity, a transfer by a Registered Holder which is a partnership to a partner of such partnership or a retired partner of such partnership or to the estate of any such partner or retired partner, or a transfer by a Registered Holder which is a limited liability company to a member of such limited liability company or a retired member or to the estate of any such member or retired member, provided that the transferee in each case agrees in writing to be subject to the terms of this Section 5, or (ii) a transfer made in accordance with Rule 144 under the Act. (c) Each certificate representing Warrant Shares shall bear a legend substantially in the following form: "The securities represented by this certificate have not been registered under the Securities Act of 1933, as amended (the "Act"), and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such securities are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required." The foregoing legend shall be removed from the certificates representing any Warrant Shares, at the request of the holder thereof, at such time as they become eligible for resale pursuant to Rule 144(k) under the Act. (d) The Company will maintain a register containing the name and address of the Registered Holder of this Warrant. The Registered Holder may change its address as shown on the warrant register by written notice to the Company requesting such change. 6. Notices of Record Date, etc. In the event: --------------------------- (a) the Company shall take a record of the holders of its Common Stock (or other stock or securities at the time deliverable upon the exercise of this Warrant) for the purpose of entitling or enabling them to receive any dividend or other distribution, or to receive any right to subscribe for or purchase any shares of stock of any class or any other securities, or to receive any other right; or (b) of any capital reorganization of the Company, any reclassification of the Common Stock of the Company, any consolidation or merger of the Company with or into another corporation (other than a consolidation or merger in which the Company is the surviving entity and its Common Stock is not converted into or exchanged for any other securities or property), or any transfer of all or substantially all of the assets of the Company; or (c) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company, then, and in each such case, the Company will send or cause to be sent to the -5-

Registered Holder a notice specifying, as the case may be, (i) the record date for such dividend, distribution or right, and the amount and character of such dividend, distribution or right, or (ii) the effective date on which such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock (or such other stock or securities at the time deliverable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other stock or securities) for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, transfer, dissolution, liquidation or winding-up. Such notice shall be sent at least 10 days prior to the record date or effective date for the event specified in such notice. 7. Reservation of Stock. The Company will at all times reserve and keep --------------------- available, solely for issuance and delivery upon the exercise of this Warrant, such number of Warrant Shares and other securities, cash and/or property, as from time to time shall be issuable upon the exercise of this Warrant. 8. Replacement Warrant. Upon receipt of evidence reasonably satisfactory ------------------- to the Company of the loss, theft, destruction or mutilation of this Warrant and (in the case of loss, theft or destruction) upon delivery of an indemnity agreement (with surety if reasonably required) in an amount reasonably satisfactory to the Company, or (in the case of mutilation) upon surrender and cancellation of this Warrant, the Company will issue, in lieu thereof, a new Warrant of like tenor. 9. Agreement in Connection with Public Offering. The Registered Holder --------------------------------------------- agrees, in connection with an underwritten public offering of the Company's securities pursuant to a registration statement under the Act, (i) not to sell, make short sale of, loan, grant any options for the purchase of, or otherwise dispose of any shares of Common Stock held by the Registered Holder (other than any shares included in the offering) without the prior written consent of the Company or the underwriters managing such underwritten public offering of the Company's securities for a period of 180 days from the effective date of such registration statement, and (ii) to execute any agreement reflecting clause (i) above as may be requested by the Company or the managing underwriters at the time of such offering. 10.

          (b) Method of  Exercise.  The  Registered  Holder  may, at its option,
              -------------------

part and at any time or from time to time, by  surrendering  this Warrant,  with
the purchase form appended  hereto as Exhibit I duly executed by or on behalf of
                                      ---------

(c) Exercise Date. Each exercise of this Warrant shall be deemed to -------------- have been effected immediately prior to the close of business on the day on which this Warrant shall have been surrendered to the Company as provided in subsection 1(b) above (the "Exercise Date"). At such time, the person or persons in whose name or names any certificates for Warrant Shares shall be issuable upon such exercise as provided in subsection 1(d) below shall be deemed to have become the holder or holders of record of the Warrant Shares represented by such certificates. (d) Issuance of Certificates. As soon as practicable after the -------------------------- exercise of this Warrant in whole or in part, and in any event within 10 days thereafter, the Company, at its expense, will cause to be issued in the name of, and delivered to, the Registered Holder, or as the Registered Holder (upon payment by the Registered Holder of any applicable transfer taxes) may direct: (i) a certificate or certificates for the number of full Warrant Shares to which the Registered Holder shall be entitled upon such exercise, which shall include, if applicable, the rounding of any fraction up to the nearest whole number of shares of Common Stock pursuant to Section 3 hereof; and (ii) in case such exercise is in part only, a new warrant or warrants (dated the date hereof) of like tenor, calling in the aggregate on the face or faces thereof for the number of Warrant Shares equal (without giving effect to any adjustment therein) to the number of such shares called for on the face of this Warrant minus the number of Warrant Shares for which this Warrant was so exercised. 2. Adjustments. ----------- (a) Adjustment for Stock Splits and Combinations. If the Company shall -------------------------------------------- at any time or from time to time after the date on which this Warrant was first issued (or, if this Warrant was issued upon partial exercise of, or in replacement of, another warrant of like tenor, then the date on which such original warrant was first issued) (either such date being referred to as the "Original Issue Date") effect a subdivision of the outstanding Common Stock, the Purchase Price then in effect immediately before that subdivision shall be proportionately decreased.

Any adjustment under this paragraph shall become effective at the close of business on the date the subdivision or combination becomes effective. (b) Adjustment for Certain Dividends and Distributions. In the event --------------------------------------------------- the Company at any time, or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of Common Stock, then and in each such event the Purchase Price then in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Purchase Price then in effect by a fraction: (1) the numerator of which shall be the total number of shares -2-

of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (2) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution; provided, however, that if such record date shall have been fixed and such - -------- ------- dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Purchase Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Purchase Price shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends or distributions. (c) Adjustment in Number of Warrant Shares. When any adjustment is --------------------------------------- required to be made in the Purchase Price pursuant to subsections 2(a) or 2(b), the number of Warrant Shares purchasable upon the exercise of this Warrant shall be changed to the number determined by dividing (i) an amount equal to the number of shares issuable upon the exercise of this Warrant immediately prior to such adjustment, multiplied by the Purchase Price in effect immediately prior to such adjustment, by (ii) the Purchase Price in effect immediately after such adjustment. (d) Adjustments for Other Dividends and Distributions. In the event --------------------------------------------------- the Company at any time or from time to time after the Original Issue Date shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of the Company (other than shares of Common Stock) or in cash or other property (other than regular cash dividends paid out of earnings or earned surplus, determined in accordance with generally accepted accounting principles), then and in each such event provision shall be made so that the Registered Holder shall receive upon exercise hereof, in addition to the number of shares of Common Stock issuable hereunder, the kind and amount of securities of the Company, cash or other property which the Registered Holder would have been entitled to receive had this Warrant been exercised on the date of such event and had the Registered Holder thereafter, during the period from the date of such event to and including the Exercise Date, retained any such securities receivable during such period, giving application to all adjustments called for during such period under this Section 2 with respect to the rights of the Registered Holder. (e) Adjustment for Reorganization. If there shall occur any --------------------------------- reorganization, recapitalization, reclassification, consolidation or merger involving the Company in which the Common Stock is converted into or exchanged for securities, cash or other property (other than a transaction covered by subsections 2(a), 2(b) or 2(d)) (collectively, a "Reorganization"), then, following such Reorganization, the Registered Holder shall receive upon exercise hereof the kind and amount of securities, cash or other property which the Registered Holder would have been entitled to receive pursuant to such Reorganization if such exercise had taken place immediately prior to such Reorganization. In any such case, appropriate adjustment (as determined in good faith by the Board) shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Registered Holder, to the end that the provisions set forth in this Section 2 (including provisions with respect to changes in and other adjustments of -3-

the Purchase Price) shall thereafter be applicable, as nearly as reasonably may be, in relation to any securities, cash or other property thereafter deliverable upon the exercise of this Warrant. (f) Certificate as to Adjustments. Upon the occurrence of each -------------------------------- adjustment or readjustment of the Purchase Price pursuant to this Section 2, the Company at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Registered Holder a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property for which this Warrant shall be exercisable and the Purchase Price) and showing in detail the facts upon which such adjustment or readjustment is based. The Company shall, as promptly as reasonably practicable after the written request at any time of the Registered Holder (but in any event not later than 10 days thereafter), furnish or cause to be furnished to the Registered Holder a certificate setting forth (i) the Purchase Price then in effect and (ii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the exercise of this Warrant. 3. Fractional Shares. The Company shall not be required upon the exercise ------------------ of this Warrant to issue any fractions of shares of Common Stock or fractional Warrants; provided, however, that if the Registered Holder exercises this -------- ------- Warrant, any fractional shares of Common Stock shall be eliminated by rounding any fraction up to the nearest whole number of shares of Common Stock.

Investment Representations. The initial Registered Holder represents ---------------------------- and warrants to the Company as follows: (a) Investment. It is acquiring the Warrant, and (if and when it ---------- exercises this Warrant) it will acquire the Warrant Shares, for its own account for investment and not with a view to, or for sale in connection with, any distribution thereof, nor with any present intention of distributing or selling the same; and the Registered Holder has no present or contemplated agreement, undertaking, arrangement, obligation, indebtedness or commitment providing for the disposition thereof; (b) Federal and State Compliance.

and must be held indefinitely unless subsequently registered under the Act or an exemption from such registration is available. 5.

C. Capitalization.

Except for customary transfer restrictions contained in agreements entered into by the Company in order to sell restricted securities or as provided in the Commission Documents, the Company is not a party to any agreement granting registration rights to any person with respect to any of its equity or debt securities. Except as set forth in the Commission Documents, the offer and sale of all capital stock, convertible securities, rights, warrants, or options of the Company issued prior to the date hereof complied with all applicable federal and state securities laws, and no stockholder has a right of rescission or damages with respect thereto which would have a Material Adverse Effect.

The Purchaser agrees to indemnify and hold harmless the Company and its directors, officers, affiliates, agents, successors and assigns from and against any and all actual losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys fees, charges and disbursements but excluding consequential damages) incurred by the Company as result of any breach of the representations and covenants made by the Purchaser herein, in the Warrant and the Registration Rights Agreement, except where such misrepresentation or breach is caused by the Company. B. Indemnification Procedure. Any party entitled to indemnification under -------------------------- this Section (an "indemnified party") will give written notice to the indemnifying party of any matters giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnified party a conflict of interest between it and the indemnifying party may exist with respect of such action, proceeding or claim, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party's costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior -13-

written consent. Notwithstanding anything in this Section to the contrary, the indemnifying party shall not, without the indemnified party's prior written consent (which consent shall not be unreasonably withheld), settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification required by this Section shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party irrevocably agrees to refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law. SECTION VI POST CLOSING CONDITIONS ----------------------- A. Registration of Warrant Shares. The Company shall cause all of the -------------------------------- Warrant Shares to be registered on a Form S-3 registration statement, or such similar form, under the Securities Act on or before June 30, 2002.

SECTION VII MISCELLANEOUS ------------- A. Entire Agreement. This Agreement contains the entire agreement between ---------------- the parties hereto with respect to the transactions contemplated hereby, and no modification hereof shall be effective unless in writing and signed by the party against which it is sought to be enforced. B. Invalidity, Etc. If any provision of this Agreement, or the application ---------------- of any such provision to any person or circumstance, shall be held invalid by a court of competent jurisdiction, the remainder of this Agreement, or the application of such provision to persons or circumstances other than those as to which it is held invalid, shall not be affected thereby. C. Headings. The headings of this Agreement are for convenience of -------- reference only and are not part of the substance of this Agreement. D. Binding Effect. This Agreement shall be binding upon and inure to the --------------- benefit of the parties hereto and their respective successors and assigns. E. Governing Law.

The Purchaser agrees to indemnify and hold harmless the Company and its directors, officers, affiliates, agents, successors and assigns from and against any and all actual losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys fees, charges and disbursements but excluding consequential damages) incurred by the Company as result of any breach of the representations and covenants made by the Purchaser herein, in the Warrant and the Registration Rights Agreement, except where such misrepresentation or breach is caused by the Company. B. Indemnification Procedure. Any party entitled to indemnification under -------------------------- this Section (an "indemnified party") will give written notice to the indemnifying party of any matters giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnified party a conflict of interest between it and the indemnifying party may exist with respect of such action, proceeding or claim, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim.

The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding -14-

effected without its prior written consent. Notwithstanding anything in this Section to the contrary, the indemnifying party shall not, without the indemnified party's prior written consent (which consent shall not be unreasonably withheld), settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification required by this Section shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party irrevocably agrees to refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law.

The Purchaser agrees to indemnify and hold harmless the Company and its directors, officers, affiliates, agents, successors and assigns from and against any and all actual losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys fees, charges and disbursements but excluding consequential damages) incurred by the Company as result of any breach of the representations and covenants made by the Purchaser herein, in the Warrant and the Registration Rights Agreement, except where such misrepresentation or breach is caused by the Company. B. Indemnification Procedure. Any party entitled to indemnification under -------------------------- this Section (an "indemnified party") will give written notice to the indemnifying party of any matters giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnified party a conflict of interest between it and the indemnifying party may exist with respect of such action, proceeding or claim, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party's costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior -13-

written consent. Notwithstanding anything in this Section to the contrary, the indemnifying party shall not, without the indemnified party's prior written consent (which consent shall not be unreasonably withheld), settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification required by this Section shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party irrevocably agrees to refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law. -14-

(d) Notwithstanding anything to the contrary contained herein, if (x) the Board determines in good faith that the registration and distribution of Warrant Shares (or the use of such Shelf Registration Statement or the Prospectus contained therein) would interfere with any proposed or pending material corporate transaction involving the Company or any of its subsidiaries or would require premature disclosure thereof or would require the Company to disclose information that the Company has not otherwise made public and that the Company reasonably determines is in the best interests of the Company not to disclose at such time, and (y) the Company notifies the Holders in writing not later than three (3) days following such determination (such notice a "Blackout Notice"), the Company may, with prior consent of the Holders, which shall be in good faith and which shall not be unreasonably withheld, (A) postpone the filing of such Shelf Registration Statement or (B) allow such Shelf Registration Statement to fail to be effective and usable or elect that such Shelf Registration Statement not be usable for a reasonable period of time, but not in excess of 30 days (a "Blackout Period"); provided, however, that the Blackout Periods shall not -------- ------- extend beyond August 15, 2002. 2.3 Piggyback Registration. ---------------------- (a) At any time that the Company proposes to file a Registration Statement within three (3) years from the date hereof (other than a Registration Statement filed pursuant to Section 2.2 above), the Company shall give the Holders written notice of its intention to do so and of the intended method of sale, including the total number of shares proposed to be the subject of such registration (the "Registration Notice") within a reasonable time prior to the anticipated filing date of the Registration Statement effecting such registration but in any event at least thirty (30) days prior to the filing of such Registration Statement. Each Holder may request inclusion of any Restricted Securities in such Registration Statement by delivering to the Company, within ten (10) Business Days after receipt of the Registration Notice, a written notice (the "Piggyback Notice") stating the number of Restricted Securities proposed to be included and that such shares are to be included in any underwriting only on the same terms and conditions as the shares of Common Stock otherwise being sold through underwriters under such Registration Statement. The Company shall use its best efforts to cause all Restricted Securities specified in the Piggyback Notice to be included in the Registration Statement and any related offering, all to the 4

extent requisite to permit the sale by the Holders of such Restricted Securities in accordance with the method of sale applicable to the other shares of Common Stock included in such Registration Statement; provided, however, that if, at -------- ------- any time after giving written notice of its intention to register any securities and prior to the effective date of the Registration Statement filed in connection with such registration, the Company shall determine for any reason not to register or to delay registration of such securities, the Company may, at its election, give written notice of such determination to each Holder of Restricted Securities and, thereupon: (i) in the case of a determination not to register, shall be relieved of its obligation to register any Restricted Securities in connection with such cancelled registration (but not from its obligation to pay the Registration Expenses, as defined in Section 2.7, in connection therewith), and (ii) in the case of a delay in registering, shall be permitted to delay registering any Restricted Securities for the same period as the delay in registering such other securities. (b) The Company's obligation to include Restricted Securities in a Registration Statement pursuant to Section 2.3(a) shall be subject to the following limitations: (i) The Company shall not be obligated to include any Restricted Securities in a Registration Statement filed on Form S-4, Form S-8 or such other similar successor forms then in effect under the Securities Act. (ii) If a Registration Statement involves an underwritten offering and the managing underwriter advises the Company in writing that, in its opinion, the number of the Restricted Securities requested to be included in such Registration Statement exceeds the number which can be sold in such offering without adversely affecting the offering, the Company will not include any Restricted Securities in such Registration Statement, or if some of the requested Restricted Securities can be included in such Registration Statement, the Company will only include such number of Restricted Securities which the Company is so advised can be sold in such offering without adversely affecting the offering, determined as follows: (A) first, all securities proposed by the Company to be sold for its own account shall be included in the Registration Statement; (B) second, any securities proposed to be sold pursuant to the Fahnestock Registration Rights Agreements; and (C) third, any Restricted Securities requested to be included in such registration on a pari passu basis with any ---- ----- other securities of the Company which have been afforded registration rights by the Company prior to, or as of the date hereof. (c) No Holder of Restricted Securities may include any of its Restricted Securities in the Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within ten (10) Business Days after receipt of a written request therefor, 5

such information specified in Item 507 of Regulation S-K under the Securities Act or such other information as the Company may reasonably request for use in connection with the Registration Statement or Prospectus or preliminary Prospectus included therein and in any application to the NASD. Each Holder as to which the Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make all information previously furnished to the Company by such Holder not materially misleading. 2.4 Registration Procedures. In connection with any Registration Statement ----------------------- and any Prospectus required by this Agreement to permit the sale or resale of Restricted Securities, the Company shall: (a) prepare and file with the Commission such amendments and post-effective amendments to such Registration Statement as may be necessary to keep such Registration Statement effective until such time as all of such securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof set forth in such Registration Statement; cause the Prospectus to be supplemented by any required Prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A, as applicable, under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement or the Prospectus; (b) promptly (and in respect of events covered by clause (i) hereof, on the same day as the Company shall receive notice of effectiveness) advise the Holders covered by such Registration Statement and, if requested by such Persons, confirm such advice in writing, (i) when the Prospectus or any Prospectus supplement or post-effective amendment has been filed, and when the same has become effective, (ii) of any request by the Commission for post-effective amendments to such Registration Statement or post-effective amendments to such Registration Statement or post-effective amendments or supplements to the Prospectus or for additional information relating thereto, (iii) of the issuance by the Commission of any stop order suspending the effectiveness of any such Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, and (iv) of the existence of any fact or the happening of any event that makes any statement of a material fact made in any such Registration Statement, the related Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in any such Registration Statement or the related Prospectus in order to make the statements therein not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of such Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Restricted Securities under state securities or Blue Sky laws, the Company shall use its reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time; (c) promptly furnish to each Holder of Restricted Securities covered by any 6

Registration Statement, and each underwriter, if any, without charge, at least one conformed copy of any Registration Statement, as first filed with the Commission, and of each amendment thereto, including all documents incorporated by reference therein and all exhibits (including exhibits incorporated therein by reference) and any related correspondence between the Company and its counsel or accountants and the Commission or staff of the Commission and such other documents as such Holder may reasonably request; (d) deliver to each Holder covered by any Registration Statement, and each underwriter, if any, without charge, as many copies of the Prospectus (including each preliminary prospectus) and any amendment or supplement thereto as such Person reasonably may request; (e) enter into such customary agreements and take all such other reasonable action in connection therewith (including those reasonably requested by the selling Holders or the underwriter(s), if any) required in order to expedite or facilitate the disposition of such Restricted Securities pursuant to such Registration Statement, including, but not limited to, dispositions pursuant to an underwritten registration, and in such connection: (i) make such representations and warranties to the selling Holders and underwriter(s), if any, in form, substance and scope as are customarily made by issuers to underwriters in underwritten offerings (whether or not sales of securities pursuant to such Registration Statement are to be made to an underwriter(s)) and confirm the same if and when requested; (ii) obtain opinions of counsel to the Company (which counsel and opinions, in form and substance, shall be reasonably satisfactory to the selling Holders and the underwriter(s), if any, and their respective counsel) addressed to each selling Holder and underwriter, if any, covering the matters customarily covered in opinions requested in underwritten offerings (whether or not sales of securities pursuant to such Registration Statement are to be made to an underwriter(s)) and dated the date of effectiveness of any Registration Statement (and, in the case of any underwritten sale of securities pursuant to such Registration Statement, each closing date of sales to the underwriter(s) pursuant thereto); (iii) use reasonable efforts to obtain comfort letters dated the date of effectiveness of any Registration Statement (and, in the case of any underwritten sale of securities pursuant to such Registration Statement, each closing date of sales to the underwriter(s), if any, pursuant thereto) from the independent certified public accountants of the Company addressed to each selling Holder and underwriter, if any, such letters to be in customary form and covering matters of the type customarily covered in comfort letters in connection with underwritten offerings (whether or not sales of securities pursuant to such Registration Statement are to be made to an underwriter(s)); (iv) provide for the indemnification provisions and procedures of Section 2.8 hereof with respect to selling Holders and the underwriter(s), if any, and; (v) deliver such documents and certificates as may be reasonably requested by the selling Holders or the underwriter(s), if any, and which are customarily delivered in 7

The actions required by clauses (i) through (v) above shall be done at each closing under such underwriting or similar agreement, as and to the extent required thereunder, and if at any time the representations and warranties of the Company contemplated in clause (i) above cease to be true and correct, the Company shall so advise the underwriter(s), if any, and each selling Holder promptly, and, if requested by such Person, shall confirm such advice in writing; (f) prior to any public offering of Restricted Securities, cooperate with the selling Holders, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Restricted Securities under the securities or Blue Sky laws of such U.S. jurisdictions as the selling Holders or underwriter(s), if any, may reasonably request in writing by the time any Registration Statement is declared effective by the Commission, and do any and all other acts or filings necessary or advisable to enable disposition in such U.S. jurisdictions of the Restricted Securities covered by any Registration Statement and to file such consents to service of process or other documents as may be necessary in order to effect such registration or qualification; provided, however, that the Company shall not be required to register or qualify - -------- ------- as a foreign corporation in any jurisdiction where it is not then so qualified or as a dealer in securities in any jurisdiction where it would not otherwise be required to register or qualify but for this Section 2.4, or to take any action that would subject it to the general service of process in suits or to general taxation, in any jurisdiction where it is not then so subject; (g) in connection with any sale of Restricted Securities that will result in such securities no longer being Restricted Securities, cooperate with the selling Holders and the underwriter(s), if any, to facilitate the timely preparation and delivery of certificates representing Restricted Securities to be sold and not bearing any restrictive legends; and enable such Restricted Securities to be in such denominations and registered in such names as the Holders or the underwriter(s), if any, may request at least two (2) Business Days prior to any sale of Restricted Securities made by such underwriters; (h) use its reasonable efforts to cause the disposition of the Restricted Securities covered by any Registration Statement to be registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Restricted Securities, subject to the proviso contained in Section 2.4(f); (i) if any fact or event contemplated by Section 2.4(b) shall exist or have occurred, prepare a supplement or post-effective amendment to any Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the Purchaser of Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statement therein not misleading; (j) cooperate and assist in the performance of any due diligence investigation by any underwriter (including any "qualified independent underwriter") that is required to be retained in 8

accordance with the rules and regulations of the NASD, and use its reasonable efforts to cause any Registration Statement to become effective and approved by such U.S. governmental agencies or authorities as may be necessary to enable the Holders selling Restricted Securities to consummate the disposition of such Restricted Securities; (k) otherwise use its reasonable efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders with regard to such Registration Statement, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) for the twelve (12)- month period (i) commencing at the end of any fiscal quarter in which Restricted Securities are sold to the underwriter in a firm or best efforts underwritten offering or (ii) if not sold to an underwriter in such an offering, beginning with the first month of the Company's first fiscal quarter commencing after the effective date of any Registration Statement; (l) provide a CUSIP number for all Restricted Securities not later than the effective date of any Registration Statement; (m) use its best efforts to list, not later than the effective date of such Registration Statement, all Restricted Securities covered by such Registration Statement on the NASD OTC Electronic Bulletin Board or any other trading market on which any Common Stock of the Company are then admitted for trading; and (n) provide promptly to each Holder covered by any Registration Statement upon request each document filed with the Commission pursuant to the requirements of Section 12 and Section 14 of the Exchange Act.

If so directed by the Company, each Holder will deliver to the Company all copies, other than permanent file copies, then in such Holder's possession, of the Prospectus covering such Restricted Securities that was current at the time of receipt of such notice. 2.5 Preparation; Reasonable Investigation. In connection with the ----------------------------------------- preparation and filing of each Registration Statement under the Securities Act, the Company will give the Holders of Restricted Securities registered under such Registration Statement, their underwriter, if any, and their respective counsel and accountants, the opportunity to participate in the preparation of such Registration Statement, each prospectus included therein or filed with the Commission, and each amendment thereof or supplement thereto, and will give each of them access to its books and records and such opportunities to discuss the business, finances and 9

accounts of the Company and its subsidiaries with its officers, directors and the independent public accountants who have certified its financial statements as shall be necessary, in the opinion of such Holders and such underwriters' respective counsel, to conduct a reasonable investigation within the meaning of the Securities Act. 2.6 Certain Rights of Holders. The Company will not file any Registration ------------------------- Statement under the Securities Act which refers to any Holder of Restricted Securities by name or otherwise without the prior approval of such Holder, which consent shall not be unreasonably withheld or delayed. 2.7 Registration Expenses. --------------------- (a) All expenses incident to the Company's performance of or compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement becomes effective, including without limitation: (i) all registration and filing fees and expenses (including filings made with the NASD and reasonable counsel fees in connection therewith); (ii) all reasonable fees and expenses of compliance with federal securities and state Blue Sky or securities laws (including all reasonable fees and expenses of one counsel to the underwriter(s) in any underwriting) in connection with compliance with state Blue Sky or securities laws for all states in the United States; (iii) all expenses of printing, messenger and delivery services and telephone calls; (iv) all fees and disbursements of counsel for the Company; and (v) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance), but excluding from this paragraph, fees and expenses of counsel to the underwriter(s), if any, unless otherwise set forth herein. (b) The Company will not be responsible for any underwriting discounts, commissions or fees attributable to the sale of Restricted Securities or any legal fees or disbursements (other than any such fees or disbursements relating to Blue Sky compliance or otherwise as set forth under Section 2.7(a)) incurred by any underwriters in any underwritten offering if the underwriter participates in such underwritten offering at the request of the Holders of Restricted Securities, or any transfer taxes that may be imposed in connection with a sale or transfer of Restricted Securities. (c) The Company shall, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company. 2.8 Indemnification; Contribution. ----------------------------- (a) The Company agrees to indemnify and hold harmless (i) each Holder covered by any Registration Statement, (ii) each other Person who participates as an underwriter in the offering or sale of such securities, (iii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any such Holder or underwriter (any of the Persons referred to in this clause (iii) being hereinafter referred to as a 10

"controlling Person"), and (iv) the respective officers, directors, partners, employees, representatives and agents of any such Holder or underwriter or any controlling Person (any Person referred to in clause (i), (ii), (iii) or (iv) may hereinafter be referred to as an "indemnified Person"), to the fullest extent lawful, from and against any and all losses, claims, damages, liabilities, judgments or expenses, joint or several (or actions or proceedings, whether commenced or threatened, in respect thereof) (collectively, "Claims"), to which such indemnified Person may become subject under either Section 15 of the Securities Act or Section 20 of the Exchange Act or otherwise, insofar as such Claims arise out of or are based upon, or are caused by any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto), or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or a violation by the Company of the Securities Act or any state securities law, or any rule or regulation promulgated under the Securities Act or any state securities law, or any other law applicable to the Company relating to any such registration or qualification, except insofar as such losses, claims, damages, liabilities, judgments or expenses of any such indemnified Person; (x) are caused by any such untrue statement or omission or alleged untrue statement or omission that is based upon information relating to such indemnified Person furnished in writing to the Company by or on behalf of any of such indemnified Person expressly for use therein; (y) with respect to the preliminary Prospectus, result from the fact that such Holder sold Securities to a Person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus, as amended or supplemented, if the Company shall have previously furnished copies thereof to such Holder in accordance with this Agreement and said Prospectus, as amended or supplemented, would have corrected such untrue statement or omission; or (z) as a result of the use by an indemnified Person of any Prospectus when, upon receipt of a notice from the Company of the existence of any fact of the kind described in Section 2.4(b)(iv), the indemnified Person or the related Holder was not permitted to do so. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any indemnified Person and shall survive the transfer of such securities by such Holder. In case any action shall be brought or asserted against any of the indemnified Persons with respect to which indemnity may be sought against the Company, such indemnified Person shall promptly notify the Company and the Company shall assume the defense thereof. Such indemnified Person shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified Person unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel, or (iii) the named parties to any such action (including any implied parties) include both the indemnified Person and the Company and the indemnified Person shall have been advised in writing by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Company (in which case the Company shall not have the right to assume the defense of such action on behalf of the indemnified Person), it being understood, however, that the Company shall not, in connection with such action or similar or related actions or proceedings arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all the indemnified Persons, which firm shall be (x) designated by such indemnified Persons; and (y) 11

reasonably satisfactory to the Company. The Company shall not be liable for any settlement of any such action or proceeding effected without the Company's prior written consent, which consent shall not be withheld unreasonably, and the Company agrees to indemnify and hold harmless any indemnified Person from and against any loss, claim, damage, liability, judgment or expense by reason of any settlement of any action effected with the written consent of the Company. The Company shall not, without the prior written consent of each indemnified Person, settle or compromise or consent to the entry of judgment on or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not any indemnified Person is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each indemnified Person from all liability arising out of such action, claim litigation or proceeding. (b) Each Holder of Restricted Securities covered by any Registration Statement agrees, severally and not jointly, to indemnify and hold harmless the Company and its directors, officers and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company, and the respective officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Company to each of the indemnified Persons, but only (i) with respect to actions based on information relating to such Holder furnished in writing by or on behalf of such Holder expressly for use in any Registration Statement or Prospectus, and (ii) to the extent of the gross proceeds, if any, received by such Holder from the sale or other disposition of his or its Restricted Securities covered by such Registration Statement. In case any action or proceeding shall be brought against the Company or its directors or officers or any such controlling Person in respect of which indemnity may be sought against a Holder of Restricted Securities covered by any Registration Statement, such Holder shall have the rights and duties given the Company in Section 2.8(a) (except that the Holder may but shall not be required to assume the defense thereof), and the Company or its directors or officers or such controlling Person shall have the rights and duties given to each Holder by Section 2.8(a). (c) If the indemnification provided for in this Section 2.8 is unavailable to an indemnified party under Section 2.8(a) or (b) (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments or expenses referred to therein, then each applicable indemnifying party (in the case of the Holders severally and not jointly), in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities, judgments or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Holder on the other hand from sale of Restricted Securities, or (ii) if such allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and such Holder in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities, judgments or expenses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of such Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by such Holder and the parties relative intent, 12

knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid to a party as a result of the losses, claims, damages, liabilities judgments and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 2.8(a), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The Company and each Holder of Restricted Securities covered by any Registration Statement agree that it would not be just and equitable if contribution pursuant to this Section 2.8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 2.8(c), no Holder (and none of its related indemnified Persons) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the dollar amount of proceeds received by such Holder upon the sale of the Restricted Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentations (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The indemnity and contribution provisions contained in this Section 2.8 are in addition to any liability which the indemnifying Person may otherwise have to the indemnified Persons referred to above. 2.9 Participation in Underwritten Registrations. No Holder may participate -------------------------------------------- in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 2.10 Selection of Underwriters. The Holders of Restricted Securities --------------------------- covered by any Registration Statement who desire to do so may sell such Restricted Securities in an underwritten offering. In any such underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Company. Such investment bankers and managers are referred to herein as the "underwriters." 13

not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus, as amended or supplemented, if the Company shall have previously furnished copies thereof to such Holder in accordance with this Agreement and said Prospectus, as amended or supplemented, would have corrected such untrue statement or omission; or (z) as a result of the use by an indemnified Person of any Prospectus when, upon receipt of a notice from the Company of the existence of any fact of the kind described in Section 2.3(b)(iv), the indemnified Person or the related Holder was not permitted to do so. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any indemnified Person and shall survive the transfer of such securities by such Holder. In case any action shall be brought or asserted against any of the indemnified Persons with respect to which indemnity may be sought against the Company, such indemnified Person shall promptly notify the Company and the Company shall assume the defense thereof. Such indemnified Person shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified Person unless (i) the employment of such counsel shall have been specifically authorized in writing by the Company, (ii) the Company shall have failed to assume the defense and employ counsel, or (iii) the named parties to any such action (including any implied parties) include both the indemnified Person and the Company and the indemnified Person shall have been advised in writing by its counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the Company (in which case the Company shall not have the right to assume the defense of such action on behalf of the indemnified Person), it being understood, however, that the Company shall not, in connection with such action or similar or related actions or proceedings arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for all the indemnified Persons, which firm shall be (x) designated by such indemnified Persons; and (y) reasonably satisfactory to the Company. The Company shall not be liable for any settlement of any such action or proceeding effected without the Company's prior written consent, which consent shall not be withheld unreasonably, and the Company agrees to indemnify and hold harmless any indemnified Person from and against any loss, claim, damage, liability, judgment or expense by reason of any settlement of any action effected with the written consent of the Company. The Company shall not, without the prior written consent of each indemnified Person, settle or compromise or consent to the entry of judgment on or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not any indemnified Person is a party thereto), unless such settlement, compromise, consent or termination includes an unconditional release of each indemnified Person from all liability arising out of such action, claim litigation or proceeding. (b) Each Holder of Restricted Securities covered by any Registration Statement agrees, severally and not jointly, to indemnify and hold harmless the Company and its directors, officers and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Company, and the respective officers, directors, partners, employees, representatives and agents of each, to the same extent as the foregoing indemnity from the Company to each of the indemnified Persons, but only (i) with ---- respect to actions based on information relating to such Holder furnished in writing by or on behalf of such Holder 10

expressly for use in any Registration Statement or Prospectus, and (ii) to the extent of the gross proceeds, if any, received by such Purchaser from the sale or other disposition of his or its Restricted Securities covered by such Registration Statement. In case any action or proceeding shall be brought against the Company or its directors or officers or any such controlling Person in respect of which indemnity may be sought against a Holder of Restricted Securities covered by any Registration Statement, such Holder shall have the rights and duties given the Company in Section 2.7(a) (except that the Holder may but shall not be required to assume the defense thereof), and the Company or its directors or officers or such controlling Person shall have the rights and duties given to each Holder by Section 2.7(a). (c) If the indemnification provided for in this Section 2.7 is unavailable to an indemnified party under Section 2.7(a) or (b) (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities, judgments or expenses referred to therein, then each applicable indemnifying party (in the case of the Holders severally and not jointly), in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims damages, liabilities, judgments or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Holder on the other hand from sale of Restricted Securities, or (ii) if such allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and such Holder in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities, judgments or expenses, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of such Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by such Holder and the parties relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid to a party as a result of the losses, claims, damages, liabilities judgments and expenses referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 2.7(a), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The Company and each Holder of Restricted Securities covered by any Registration Statement agree that it would not be just and equitable if contribution pursuant to this Section 2.7(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this Section 2.7(c), no Holder (and none of its related indemnified Persons) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the dollar amount of proceeds received by such Holder upon the sale of the Restricted Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentations (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 11

The indemnity and contribution provisions contained in this Section 2.7 are in addition to any liability which the indemnifying Person may otherwise have to the indemnified Persons referred to above. 2.8 Participation in Underwritten Registrations. No Holder may participate ------------------------------------------- in any underwritten registration hereunder unless such Holder (a) agrees to sell such Holder's Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements. 2.9 Selection of Underwriters. The Holders of Restricted Securities covered ------------------------- by any Registration Statement who desire to do so may sell such Restricted Securities in an underwritten offering. In any such underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering will be selected by the Company. Such investment bankers and managers are referred to herein as the "underwriters." ARTICLE 3 MISCELLANEOUS 3.1 Entire Agreement.

(ii) Multiple Administrative Bodies. If permitted by Rule -------------------------------- 16b-3, the Plan may be administered by different bodies with respect to directors, non-director officers and Employees who are neither directors nor officers. -3-

(iii) Administration With Respect to Consultants and Other ----------------------------------------------------- Employees. With respect to grants of Options or stock icers of --------- the Company or to Consultants, the Plan shall be administered by (A) the Board, if the Board may administer the Plan in compliance with Rule 16b-3, or (B) a Committee designated by the Board, which Committee shall be constituted in such a manner as to satisfy the legal requirements relating to the administration of incentive stock option plans, if any, of Idaho corporate law and applicable securities laws and of the Code (the "Applicable Laws").

From time to time the Board may increase the size of the Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in substitution therefor, fill vacancies, however caused, and remove all members of the Committee and thereafter directly administer the Plan, all to the extent permitted by the Applicable Laws. (b) Powers of the Administrator. Subject to the provisions of the Plan --------------------------- and in the case of a Committee, the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion: (i) to determine the Fair Market Value of the Common Stock, in accordance with Section 2(k) of the Plan; (ii) to select the officers, Consultants and Employees to whom Options and stock purchase rights may from time to time be granted hereunder; (iii) to determine whether and to what extent Options and stock purchase rights or any combination thereof, are granted hereunder; (iv) to determine the number of shares of Common Stock to be covered by each such award granted hereunder; (v) to approve forms of agreement for use under the Plan; (vi) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any award granted hereunder (including, but not limited to, the share price and any restriction or limitation or waiver of forfeiture restrictions regarding any Option or other award and/or the shares of Common Stock relating thereto, based in each case on such factors as the Administrator shall determine, in its sole discretion); (vii) to determine whether and under what circumstances an Option may be settled in cash under subsection 9(f) instead of Common Stock; -4-

(viii) to determine whether, to what extent and under what circumstances Common Stock and other amounts payable with respect to an award under this Plan shall be deferred either automatically or at the election of the participant (including providing for and determining the amount, if any, of any deemed earnings on any deferred amount during any deferral period); (ix) to reduce the exercise price of any Option to the then current Fair Market Value if the Fair Market Value of the Common Stock covered by such Option shall have declined since the date the Option was granted; and (x) to determine the terms and restrictions applicable to stock purchase rights and the Restricted Stock purchased by exercising such stock purchase rights. (c) Effect of Committee's Decision. All decisions, determinations and ------------------------------ interpretations of the Administrator shall be final and binding on all Optionees and any other holders of any Options. 5. Eligibility. ----------- (a) Nonstatutory Stock Options may be granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees. An Employee or Consultant who has been granted an Option may, if he is otherwise eligible, be granted an additional Option or Options. (b) Each Option shall be designated in the written option agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designations, to the extent that the aggregate Fair Market Value of the Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. (c) For purposes of Section 5(b), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares is granted. (d) The Plan shall not confer upon any Optionee any right with respect to continuation of employment or consulting relationship with the Company, nor shall it interfere in any way with his right or the Company's right to terminate his employment or consulting relationship at any time, with or without cause. 6. Term of Plan. The Plan shall become effective upon the earlier to occur ------------ of its adoption by the Board of Directors or its approval by the shareholders of the Company as -5-

described in Section 19 of the Plan. It shall continue in effect for a term of ten (10) years unless sooner terminated under Section 15 of the Plan. 7. Term of Option. The term of each Option shall be the term stated in the -------------- Option Agreement; provided, however, that in the case of an Incentive Stock Option, the term shall be no more than ten (10) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. However, in the case of an Option granted to an Optionee who, at the time the Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Option shall be five (5) years from the date of grant thereof or such shorter term as may be provided in the Option Agreement. 8. Option Exercise Price and Consideration. --------------------------------------- (a) The per share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Board, but shall be subject to the following: (i) In the case of an Incentive Stock Option (A) granted to an Employee who, at the time of the grant of such Incentive Stock Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant. (B) granted to any Employee, the per Share exercise price shall be no less than 100% of the Fair Market Value per Share on the date of grant. (ii) In the case of a Nonstatutory Stock Option (A) granted to a person who, at the time of the grant of such Option, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of the grant. (B) granted to any person, the per Share exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant. (b) The consideration to be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist -6-

entirely of (1) cash, (2) check, (3) promissory note, (4) other Shares which (x) in the case of Shares acquired upon exercise of an Option either have been owned by the Optionee for more than six months on the date of surrender or were not acquired, directly or indirectly, from the Company, and (y) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which said Option shall be exercised, (5) authorization from the Company to retain from the total number of Shares as to which the Option is exercised that number of Shares having a Fair Market Value on the date of exercise equal to the exercise price for the total number of Shares as to which the option is exercised, (6) delivery of a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company the amount of sale or loan proceeds required to pay the exercise price, (7) by delivering an irrevocable subscription agreement for the Shares which irrevocably obligates the option holder to take and pay for the Shares not more than twelve months after the date of delivery of the subscription agreement, (8) any combination of the foregoing methods of payment, or (9) such other consideration and method of payment for the issuance of Shares to the extent permitted under Applicable Laws. In making its determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company. 9. Exercise of Option. ------------------ (a) Procedure for Exercise; Rights as a Shareholder. Any Option ---------------------------------------------------- granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, including performance criteria with respect to the Company and/or the Optionee, and as shall be permissible under the terms of the Plan. An Option may not be exercised for a fraction of a Share. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise the Option and full payment for the Shares with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Administrator, consist of any consideration and method of payment allowable under Section 8(b) of the Plan. Until the issuance (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company) of the stock certificate evidencing such Shares, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such stock certificate promptly upon exercise of the Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 11 of the Plan. -7-

Exercise of an Option in any manner shall result in a decrease in the number of Shares which thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which the Option is exercised. (b) Termination of Employment. In the event of termination of an --------------------------- Optionee's consulting relationship or Continuous Status as an Employee with the Company (as the case may be), such Optionee may, but only within ninety (90) days (or such other period of time as is determined by the Board, with such determination in the case of an Incentive Stock Option being made at the time of grant of the Option and not exceeding ninety (90) days) after the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise his Option to the extent that Optionee was entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of such termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. (c) Disability of Optionee. Notwithstanding the provisions of Section ---------------------- 9(b) above, in the event of termination of an Optionee's consulting relationship or Continuous Status as an Employee as a result of his total and permanent disability (as defined in Section 22(e)(3) of the Code), Optionee may, but only within twelve (12) months from the date of such termination (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), exercise the Option to the extent otherwise entitled to exercise it at the date of such termination. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. (d) Death of Optionee. In the event of the death of an Optionee, the ----------------- Option may be exercised, at any time within twelve (12) months following the date of death (but in no event later than the expiration date of the term of such Option as set forth in the Option Agreement), by the Optionee's estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent the Optionee was entitled to exercise the Option at the date of death. To the extent that Optionee was not entitled to exercise the Option at the date of termination, or if Optionee does not exercise such Option to the extent so entitled within the time specified herein, the Option shall terminate. (e) Rule 16b-3. Options granted to persons subject to Section 16(b) of ---------- the Exchange Act must comply with Rule 16b-3 and shall contain such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. (f) Buyout Provisions. The Administrator may at any time offer to buy ----------------- out for a payment in cash or Shares, an Option previously granted, based on such terms and -8-

conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made. 10. Non-Transferability of Options. The Option may not be sold, pledged, ------------------------------- assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. The terms of the Option shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 11. Stock Purchase Rights. --------------------- (a) Rights to Purchase. Stock purchase rights may be issued either ------------------ alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made outside of the Plan. After the Administrator determines that it will offer stock purchase rights under the Plan, it shall advise the offeree in writing of the terms, conditions and restrictions related to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid (which price shall not be less than 50% of the Fair Market Value of the Shares as of the date of the offer), and the time within which such person must accept such offer, which shall in no event exceed thirty (30) days from the date upon which the Administrator made the determination to grant the stock purchase right. The offer shall be accepted by execution of a Restricted Stock purchase agreement in the form determined by the Administrator. (b) Repurchase Option. Unless the Administrator determines otherwise, ----------------- the Restricted Stock purchase agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser's employment with the Company for any reason (including death or Disability). The purchase price for Shares repurchased pursuant to the Restricted Stock purchase agreement shall be the original price paid by the purchaser and may be paid by cancellation of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Committee may determine. (c) Other Provisions. The Restricted Stock purchase agreement shall ----------------- contain such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock purchase agreements need not be the same with respect to each purchaser. (d) Rights as a Shareholder. Once the stock purchase right is -------------------------- exercised, the purchaser shall have the rights equivalent to those of a shareholder, and shall be a shareholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock purchase right is exercised, except as provided in Section 13 of the Plan. -9-

12. Stock Withholding to Satisfy Withholding Tax Obligations. At the ------------------------------------------------------------- discretion of the Administrator, Optionees may satisfy withholding obligations as provided in this paragraph. When an Optionee incurs tax liability in connection with an Option or stock purchase right, which tax liability is subject to tax withholding under applicable tax laws, and the Optionee is obligated to pay the Company an amount required to be withheld under applicable tax laws, the Optionee may satisfy the withholding tax obligation by electing to have the Company withhold from the Shares to be issued upon exercise of the Option, or the Shares to be issued in connection with the stock purchase right, if any, that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined (the "Tax Date"). All elections by an Optionee to have Shares withheld for this purpose shall be made in writing in a form acceptable to the Administrator and shall be subject to the following restrictions: (a) the election must be made on or prior to the applicable Tax Date; (b) once made, the election shall be irrevocable as to the particular Shares of the Option or Right as to which the election is made; (c) all elections shall be subject to the consent or disapproval of the Administrator; (d) if the Optionee is subject to Rule 16b-3, the election must comply with the applicable provisions of Rule 16b-3 and shall be subject to such additional conditions or restrictions as may be required thereunder to qualify for the maximum exemption from Section 16 of the Exchange Act with respect to Plan transactions. In the event the election to have Shares withheld is made by an Optionee and the Tax Date is deferred under Section 83 of the Code because no election is filed under Section 83(b) of the Code, the Optionee shall receive the full number of Shares with respect to which the Option or stock purchase right is exercised but such Optionee shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 13. Adjustments Upon Changes in Capitalization or Merger. Subject to any ----------------------------------------------------- required action by the shareholders of the Company, the number of shares of Common Stock covered by each outstanding Option, and the number of shares of Common Stock which have been authorized for issuance under the Plan but as to which no Options have yet been granted or which have been returned to the Plan upon cancellation or expiration of an Option, as well as the price per share of Common -10-

Stock covered by each such outstanding Option, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been "effected without receipt of consideration." Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option. In the event of the proposed dissolution or liquidation of the Company, the Board shall notify the Optionee at least fifteen (15) days prior to such proposed action. To the extent it has not been previously exercised, the Option will terminate immediately prior to the consummation of such proposed action. In the event of a merger or consolidation of the Company with or into another corporation or the sale of all or substantially all of the Company's assets (hereinafter, a "merger"), the Option shall be assumed or an equivalent option shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation. In the event that such successor corporation does not agree to assume the Option or to substitute an equivalent option, the Board shall, in lieu of such assumption or substitution, provide for the Optionee to have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which the Option would not otherwise be exercisable. If the Board makes an Option fully exercisable in lieu of assumption or substitution in the event of a merger, the Board shall notify the Optionee that the Option shall be fully exercisable for a period of fifteen (15) days from the date of such notice, and the Option will terminate upon the expiration of such period. For the purposes of this paragraph, the Option shall be considered assumed if, following the merger, the Option or right confers the right to purchase, for each Share of stock subject to the Option immediately prior to the merger, the consideration (whether stock, cash, or other securities or property) received in the merger by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger was not solely common stock of the successor corporation or its Parent, the Board may, with the consent of the successor corporation and the participant, provide for the consideration to be received upon the exercise of the Option, for each Share of stock subject to the Option, to be solely common stock of the successor corporation or its Parent equal in Fair Market Value to the per share consideration received by holders of Common Stock in the merger or sale of assets. 14. Time of Granting Options. The date of grant of an Option shall, for all ------------------------ purposes, be the date on which the Administrator makes the determination granting such Option, or such other date as is determined by the Board. Notice of the determination shall be given to each -11-

Employee or Consultant to whom an Option is so granted within a reasonable time after the date of such grant. 15. Amendment and Termination of the Plan. ------------------------------------- (a) Amendment and Termination. The Board may at any time amend, alter, ------------------------- suspend or discontinue the Plan, but no amendment, alteration, suspension or discontinuation shall be made which would impair the rights of any Optionee under any grant theretofore made, without his or her consent. In addition, to the extent necessary and desirable to comply with Rule 16b-3 under the Exchange Act or with Section 422 of the Code (or any other applicable law or regulation, including the requirements of the NASD or an established stock exchange), the Company shall obtain shareholder approval of any Plan amendment in such a manner and to such a degree as required. (b) Effect of Amendment or Termination. Any such amendment or -------------------------------------- termination of the Plan shall not affect Options already granted and such Options shall remain in full force and effect as if this Plan had not been amended or terminated, unless mutually agreed otherwise between the Optionee and the Board, which agreement must be in writing and signed by the Optionee and the Company. 16.

TERMINATION. ----------- (a) For Cause by the Company. ------------------------ Employee's employment hereunder may be terminated by the Company for cause. For purposes of this Agreement, "cause" shall mean: (i) Employee's failure to substantially perform duties hereunder consistent with the terms hereof within twenty (20) business days following Employee's receipt of written notice of such failure (which notice shall have been authorized by the Board of Directors and shall set forth in reasonable detail the purported failure to perform and the specific steps to cure such failure, which shall be consistent with the terms hereof); (ii) misappropriation of Company funds or willful misconduct which results in material damage to the Company; (iii) Employee's conviction of, or plea of nolo contendere to, any crime constituting a felony under the laws of the United States or any State thereof, or any crime constituting a misdemeanor under any such law involving moral turpitude; or (iv) Employee's material breach of any of the material provisions of this Agreement, which breach Employee has failed to cure within twenty (20) business days after receipt of written notice by Employee of such breach or which breach Employee has failed to begin to attempt to cure during said twenty (20)-day period if the breach requires more than the twenty (20)-day period to cure. Any termination of Employee's employment pursuant to this Subsection 7(a) shall be made by delivery to Employee of a copy of a resolution duly adopted by 4

If Company terminates Employee's employment under the terms of this Agreement and Employee does not receive disability insurance payments under the terms hereof in an amount at least equal to the then effective Employee's Base Salary pursuant to a policy maintained and paid for by the Company, Company shall be responsible to continue to pay Employee's Base Salary during the then remaining Term to the extent required to bring the Employee's annual compensation (together with disability payments) up to the amount equal to the Employee's Base Salary immediately prior to the 5

termination for Disability. The Employee shall also receive a pro rata bonus payment with respect to the portion of the year lapsed prior to the termination based on the bonus paid to the Employee for the prior year. Any question as to the existence of the Disability of Employee as to which Employee and the Company cannot agree shall be determined in writing by a qualified independent physician mutually acceptable to Employee and the Company. If Employee and the Company cannot agree as to a qualified independent physician, each shall appoint such a physician and those two physicians shall select a third who shall make such determination in writing. The determination of Disability made in writing to the Company and Employee shall be final and conclusive for all purposes of this Agreement. (ii) Upon termination of Employee's employment hereunder during the Term as a result of death, Employee's estate or named beneficiary(ies) shall receive from the Company (x) Employee's Base Salary at the rate in effect at the time of Employee's death through the end of the third month following his death occurs and pro rata bonus payment with respect to that portion of the year --- ---- lapsed prior to his death based on the bonus paid to the Employee for the prior year, and (y) the proceeds of any life insurance policy maintained for his benefit by the Company pursuant to this Agreement (or the Plans and Policies of the Company generally). (iii) All other benefits, if any, due Employee following Employee's termination of employment pursuant to this Subsection 7(b) shall be determined in accordance with the plans, policies and practices of the Company and shall be at least equal to those received by the most senior executives and no senior executive shall receive any fringe benefit that Employee does not receive. 6

(c) Without Cause by the Company or For Good Reason. ----------------------------------------------- (i) If Employee's employment is terminated by the Company without cause (other than by reason of Disability or death) or Employee resigns for Good Reason, in either case prior to a Change of Control, then Employee shall be entitled to a lump sum cash payment from the Company, payable within ten (10) days after such termination of employment, in an amount equal to one and one-half (1.5) times the Employee's Base Salary (as in effect as of the date of such termination) and the prior year's bonus. All other benefits, if any, due Employee following Employee's termination of employment pursuant to this Subsection 7(c)(i) shall be determined in accordance with the plans, policies and practices of the Company and shall be at least equal to those received by the most senior executives. (ii) If there is a Change of Control within one (1) year of the termination of this Agreement without cause by the Company, Employee shall be entitled to receive the difference between those monies he actually received upon such termination and one and one-half (1.5) times Employee's base amount as defined in Section 280G(b)(3) of the Internal Revenue code of 1986, as amended (the "Code") (the "Employee Base Amount"). (iii) If Employee's employment is terminated by the Company without cause pursuant to Subsection 7(c)(i) above, or a termination within one (1) year of Change in Control pursuant to Subsection 7(c)(ii) above, all of the Employee's stock options previously granted by the Company shall vest immediately and may be exercised by the Employee through a non-recourse promissory note secured by the underlying shares of the option grants. (iv) Subject to Subsection 7(f), if Employee's employment is terminated by the Company without cause or by Employee for Good Reason during the Term and coincident with or following a Change of Control, Employee shall be entitled to a lump sum 7

payment, payable within ten (10) days after such termination of employment, equal to the product of (x) 1.5 times (y) the Employee Base Amount. (v) For purposes of this Agreement "Good Reason" shall mean: (a) Any material breach by the Company of this Agreement; or (b) The failure of the Board of Directors to elect the Employee as an officer of the Company with the position set forth in Section 4 hereof during the Term; or (c) any action by the Company which results in a material diminution of the Employee's position set forth in Section 4 hereof or Employee's authority, duties or responsibilities, provided, that, the foregoing events shall not be deemed to constitute Good - -------- Reason unless Employee shall have notified the Board in writing of the occurrence of such event(s) and the Board shall have failed to have cured or remedied such event(s) within twenty (20) business days of its receipt of such written notice or which breach Employer has failed to begin to attempt to cure during said twenty (20)-day period if the breach is not curable during the twenty (20)-day period. (d) Termination by Employee. If Employee terminates his employment ------------------------ with the Company for any reason (other than for Good Reason) during the Term, Employee shall be entitled to the same payments he would have received if his employment had terminated by the Company for cause. (e) Change of Control. For purposes of this Agreement, "Change of ------------------ Control" shall mean: 8

(i) any transaction or series of transactions (including, without limitation, a tender offer, merger or consolidation) the result of which is that any "person" or "group" (within the meaning of Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), becomes the "beneficial" owners (as defined in Rule 13(d)(3) promulgated under the Exchange Act) of more than fifty percent (50%) of the total aggregate voting power of all classes of the voting stock of the Company and/or warrants or options to acquire such voting stock, calculated on a fully diluted basis; (ii) during any period of two (2) consecutive calendar years, individuals who at the beginning of such period constituted the Board (together with any new directors whose election by the Board or whose nomination for election by the Company's stockholders was approved by a vote of at least two-thirds of the directors then still in office who either were directors at the beginning of such period or whose election or nomination for election was previously so approved) cease for any reason to constitute a majority of the directors then in office; or (iii) a sale of assets constituting all or substantially all of the assets of the Company (determined on a consolidated basis). In the event of such Change of Control, the new entity shall be obligated to assume the terms and conditions of this Agreement. (f) Limitation on Certain Payments. ------------------------------ (i) In the event it is determined pursuant to clause (ii) below, that part or all of the consideration, compensation or benefits to be paid to Employee under this Agreement in connection with Employee's termination of employment following a Change of Control or under any other plan, arrangement or agreement in connection therewith, constitutes a "parachute payment" (or payments) under Section 280G(b)(2) of the Code, then, of the aggregate 9

present value of such parachute payments (the "Parachute Amount") exceeds three (3) times the Employee Base Amount, the amounts constituting "parachute payments" which would otherwise be payable to or for the benefit of Employee shall be reduced to the extent necessary such that the Parachute Amount is equal to three (3) times the Employee Base Amount. Employee shall have the right to choose which amounts that would otherwise be due him but for the limitations described in this paragraph shall be subject to reduction. Notwithstanding the foregoing, if it is determined that stockholder approval of the payment of such compensation and benefits will reduce the applicability of Section 280G of the Code to such payment, promptly after request by Employee, Company will undertake reasonable efforts to hold such a meeting to obtain such approval or to solicit such approval by written consent, and to obtain such approval. (ii) Any determination that a payment constitutes a parachute payment and any calculation described in this Subsection 7(f) ("determination") shall be made by the independent public accountants for the Company, and may, at Company's election, be made prior to termination of Employee's employment where Company determines that a Change in Control, as provided in this Section 7, is imminent. Such determination shall be furnished in writing no later than thirty (30) days following the date of the Change in Control by the accountants to Employee. If Employee does not agree with such determination from the accountants and within fifteen (15) days thereafter, accountants of Employee's choice must deliver to the Company their determination that in their judgment complies with the Code. If the two accountants cannot agree upon the amount to be paid to Employee pursuant to this Section 7 within ten (10) days of the delivery of the statement of Employee's accountants to the Company, the two accountants shall choose a third accountant who shall deliver their determination of the appropriate amount to be paid to Employee pursuant to this Subsection 7(f), which determination shall be final. If the 10

final determination provides for the payment of a greater amount than that proposed by the accountants of the Company, then the Company shall pay all of Employee's costs incurred in contesting such determination and all other costs incurred by the Company with respect to such determination. (iii) If the final determination made pursuant to clause (ii) of this Subsection 7(f) results in a reduction of the payments that would otherwise be paid to Employee except for the application of clause (i) of this Subsection 7(f), Employee may then elect, in his sole discretion, which and how much of any particular entitlement shall be eliminated or reduced and shall advise the Company in writing of his election within ten (10) days of the final determination of the reduction in payments. If no such election is made by Employee within such ten (10)-day period, the Company may elect which and how much of any entitlement shall be eliminated or reduced and shall notify Employee promptly of such election. Within ten (10) days following such determination and the elections hereunder, the Company shall pay to or distribute to or for the benefit of Employee such amounts as become due to Employee under this Agreement. (iv) As a result of the uncertainty in the application of Section 280G of the Code at the time of a determination hereunder, it is possible that payments will be made by the Company which should not have been made under clause (i) of this Subsection 7(f) ("Overpayment") or that additional payments which are not made by the Company pursuant to clause (i) of this Subsection 7(f) should have been made ("Underpayment"). In the event that there is a final determination by the Internal Revenue Service, or a final determination by a court of competent jurisdiction, that an Overpayment has been made, any such Overpayment shall be treated for all purposes as a loan to Employee which Employee shall repay to the Company 11

together with interest at the applicable Federal rate provided for in Section 7872(f)(2) of the Code. In the event that there is a final determination by the Internal Revenue Service, a final determination by a court of competent jurisdiction or a change in the provisions of the Code or regulations pursuant to which an Underpayment arises under this Agreement, any such Underpayment shall be promptly paid by the Company to or for the benefit of Employee, together with interest at the applicable Federal rate provided for in Section 7872(f)(2) of the Code. (v) This Subsection 7(f) is intended to ensure that any payments made to the Employee shall comply with Section 280G of the Code, and shall not have the effect of increasing the payments otherwise due to the Employee under this Agreement. 8. NON-DISCLOSURE OF INFORMATION. ----------------------------- (a) Employee acknowledges that by virtue of his position he will be privy to the Company's confidential information and trade secrets, as they may exist from time to time, and that such confidential information and trade secrets may constitute valuable, special, and unique assets of the Company (hereinafter collectively "Confidential Information"). Accordingly, Employee shall not, during the Term and for a period of five (5) years thereafter, intentionally disclose all or any part of the Confidential Information to any person, firm, corporation, association or any other entity for any reason or purpose whatsoever, nor shall Employee and any other person by, through or with Employee, during the Term and for a period of five (5) years thereafter, intentionally make use of any of the Confidential Information for any purpose or for the benefit of any other person or entity, other than Company, under any circumstances. 12

(b) Company and Employee agree that a violation of the foregoing covenants will cause irreparable injury to the Company, and that in the event of a breach or threatened breach by Employee of the provisions of this Section 8, Company shall be entitled to an injunction restraining Employee from disclosing, in whole or in part, any Confidential Information, or from rendering any services to any person, firm, corporation, association or other entity to whom any such information, in whole or in part, has been disclosed or is threatened to be disclosed in violation of this Agreement. Nothing herein stated shall be construed as prohibiting the Company from pursuing any other rights and remedies, at law or in equity, available to the Company for such breach or threatened breach, including the recovery of damages from the Employee. (c) Notwithstanding anything contained in this Section 8 to the contrary, "Confidential Information" shall not include (i) information in the public domain as of the date hereof, (ii) information which enters the public domain hereafter through no fault of the Employee, (iii) information known to the Employee prior to his employment with the Company, or (iv) information created, discovered or developed by the Employee independent of his association with the Company. Nothing contained in this Section 8 shall be deemed to preclude the proper use by the Employee of Confidential Information in the exercise of his duties hereunder or the disclosure of Confidential Information required by law. 9. RESTRICTIVE COVENANT. -------------------- (a) During the term hereof and for a period of one (1) year after the termination of this Agreement, Employee covenants and agrees that he shall not own, manage, operate, control, be employed by, participate in, or be connected in any manner with the ownership, management, operation, or control, whether directly or indirectly, as an individual on 13

his own account, or as a partner, member, joint venturer, officer, director or shareholder of a corporation or other entity, of any business which competes with the business conducted by Company at the time of the termination or expiration of this Agreement. Notwithstanding the foregoing, (i) nothing in this Section 9 shall prohibit Employee from owning up to five percent (5%) of the outstanding voting capital stock of any corporation or other entity listed on Nasdaq or traded on any national securities exchange, and (ii) in the event of a termination by the Company without cause or a termination by the Employee for Good Reason, such restriction shall apply only if the Company has paid to the Employee all amounts required and is otherwise in compliance with Section 7 hereof. (b) Employee acknowledges that the restrictions contained in this Section 9 are reasonable. In that regard, it is the intention of the parties to this Agreement that the provisions of this Section 9 shall be enforced to the fullest extent permissible under the law and public policy applied in each jurisdiction in which enforcement is sought. Accordingly, if any portion of this Section 9 shall be adjudicated or deemed to be invalid or unenforceable, the remaining portions shall remain in full force and effect, and such invalid or unenforceable portion shall be limited to the particular jurisdiction in which such adjudication is made. 10.

Nothing in this Agreement shall be construed to prohibit Company or Employee, as the case may be, from pursuing and obtaining any other 14

available remedies which Company or Employee, as the case may be, may have for such breach or threatened breach, whether at law or in equity, including the recovery of damages from the other. 11.

or was a director, officer, employee, agent or fiduciary of the Company, or any subsidiary of the Company, or is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action or inaction on the part of Indemnitee while serving in such capacity (hereinafter an "Indemnifiable Event") against any and all expenses (including attorneys' fees and all other costs, expenses and obligations incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to defend, be a witness in or participate in, any such action, suit, proceeding, alternative dispute resolution mechanism, hearing, inquiry or investigation), judgments, fines, penalties and amounts paid in settlement (if such settlement is approved in advance by the Company, which approval shall not be unreasonably withheld) of such Claim and any federal, state, local or foreign taxes imposed on the Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement (collectively, hereinafter "Expenses"), including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses. Such payment of Expenses shall be made by the Company as soon as practicable but in any event no later than thirty (30) days after written demand by Indemnitee therefor is presented to the Company. (b) Reviewing Party. Notwithstanding the foregoing, (i) the ----------------- obligations of the Company under Section l(a) shall be subject to the condition that the Reviewing Party (as described in Section 10(e) hereof) shall not have determined (in a written opinion, in any case in which the Independent Legal Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would not be permitted to be indemnified under applicable law, and (ii) the obligation of the Company to make an advance payment of Expenses to Indemnitee pursuant to Section 2(a) (an "Expense Advance") shall be subject to the condition that, if, when and to the extent that the Reviewing Party determines that Indemnitee would not be permitted to be so indemnified under applicable law, the Company shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company) for all such amounts theretofore paid; provided, however, that if Indemnitee has commenced or thereafter commences legal proceedings in a court of competent jurisdiction to secure a determination that Indemnitee should be indemnified under applicable law, any determination made by the Reviewing Party that Indemnitee would not be permitted to be indemnified under applicable law shall not be binding and Indemnitee shall not be required to reimburse the Company for any Expense Advance until a final judicial determination is made with respect thereto (as to which all rights of appeal therefrom have been exhausted or lapsed). Indemnitee's obligation to reimburse the Company for any Expense Advance shall be unsecured and no interest shall be charged thereon. If there has not been a Change in Control (as defined in Section 10(c) hereof), the Reviewing Party shall be selected by the Board of Directors, and if there has been such a Change in Control (other than a Change in Control which has been approved by a majority of the Company's Board of Directors who were directors immediately prior to such Change in Control), the Reviewing Party shall be the Independent Legal Counsel referred to in Section l(c) hereof. If there has been no determination by the Reviewing Party or if the Reviewing Party determines that Indemnitee substantively would not be permitted to be indemnified in whole or in part under applicable law, Indemnitee shall have the right to commence litigation seeking an initial determination by the court or challenging any such determination by the Reviewing Party or any aspect thereof, including the legal or factual bases therefor, and the Company hereby consents -2-

to service of process and to appear in any such proceeding. Any determination by the Reviewing Party otherwise shall be conclusive and binding on the Company and Indemnitee. (c) Change in Control. The Company agrees that if there is a Change ----------------- in Control of the Company (other than a Change in Control which has been approved by a majority of the Company's Board of Directors who were directors immediately prior to such Change in Control) then with respect to all matters thereafter arising concerning the rights of Indemnitee to payments of Expenses and Expense Advances under this Agreement or any other agreement or under the Company's Certificate of Incorporation or By-laws as now or hereafter in effect, the Company shall seek legal advice only from Independent Legal Counsel (as defined in Section 10(d) hereof) selected by Indemnitee and approved by the Company (which approval shall not be unreasonably withheld). Such counsel, among other things, shall render its written opinion to the Company and Indemnitee as to whether and to what extent Indemnitee would be permitted to be indemnified under applicable law. The Company agrees to pay the reasonable fees of the Independent Legal Counsel referred to above and to fully indemnify such counsel against any and all expenses (including attorneys' fees), claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. (d) Mandatory Payment of Expenses. Notwithstanding any other provision ----------------------------- of this Agreement other than Section 9 hereof, to the extent that Indemnitee has been successful on the merits or otherwise, including, without limitation, the dismissal of an action without prejudice, in defense of any action, suit, proceeding, inquiry or investigation referred to in Section (1)(a) hereof or in the defense of any claim, issue or matter therein, Indemnitee shall be indemnified against all Expenses incurred by Indemnitee in connection therewith. 2. Expenses; Indemnification Procedure. ----------------------------------- (a) Advancement of Expenses. The Company shall advance all Expenses ------------------------ incurred by Indemnitee. The advances to be made hereunder shall be paid by the Company to Indemnitee as soon as practicable but in any event no later than five (5) days after written demand by Indemnitee therefor to the Company. (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition -------------------------------- precedent to Indemnitee's right to be indemnified under this Agreement, give the Company notice in writing as soon as practicable of any Claim made against Indemnitee for which indemnification will or could be sought under this Agreement. Notice to the Company shall be directed to the Chief Executive Officer of the Company at the address shown on the signature page of this Agreement (or such other address as the Company shall designate in writing to Indemnitee). In addition, Indemnitee shall give the Company such information and cooperation as it may reasonably require and as shall be within Indemnitee's power. (c) No Presumptions; Burden of Proof. For purposes of this Agreement, --------------------------------- the termination of any claim, action, suit or proceeding, by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere, or its equivalent, shall ---- ---------- -3-

not create a presumption that Indemnitee did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. In addition, neither the failure of the Reviewing Party to have made a determination as to whether Indemnitee has met any particular standard of conduct or had any particular belief, nor an actual determination by the Reviewing Party that Indemnitee has not met such standard of conduct or did not have such belief, prior to the commencement of legal proceedings by Indemnitee to secure a judicial determination that Indemnitee should be indemnified under applicable law, shall be a defense to Indemnitee's claim or create a presumption that Indemnitee has not met any particular standard of conduct or did not have any particular belief. In connection with any determination by the Reviewing Party or otherwise as to whether the Indemnitee is entitled to be indemnified hereunder, the burden of proof shall be on the Company to establish that Indemnitee is not so entitled. (d) Notice to Insurers. If, at the time of the receipt by the Company ------------------ of a notice of a Claim pursuant to Section 2(b) hereof, the Company has liability insurance in effect which may cover such Claim, the Company shall give prompt notice of the commencement of such Claim to the insurers in accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such action, suit, proceeding, inquiry or investigation in accordance with the terms of such policies. Nothing in this Section 2(d) shall limit the Company's obligations as otherwise provided for herein, including the Company's obligation to pay Expenses under Section 1(b) or to advance Expenses under Section 2(a). (e) Selection of Counsel. In the event the Company shall be obligated -------------------- hereunder to pay the Expenses of any action, suit, proceeding, inquiry or investigation, the Company, if appropriate, shall be entitled to assume the defense of such action, suit, proceeding, inquiry or investigation with counsel approved by Indemnitee, upon the delivery to Indemnitee of written notice of its election so to do. After delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same action, suit, proceeding, inquiry or investigation; provided that, (i) Indemnitee shall have the right to employ Indemnitee's counsel in any such action, suit, proceeding, inquiry or investigation at Indemnitee's expense and (ii) if (A) the employment of counsel by Indemnitee has been previously authorized by the Company, (B) Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense, or (C) the Company shall not continue to retain such counsel to defend such action, suit, proceeding, inquiry or investigation, then the fees and expenses of Indemnitee's counsel shall be at the expense of the Company. -4-

3. Additional Indemnification Rights; Nonexclusivity. ------------------------------------------------- (a) Scope. The Company hereby agrees to indemnify the Indemnitee to ----- the fullest extent permitted by law, notwithstanding that such indemnification is not specifically authorized by the other provisions of this Agreement, the Company's Certificate of Incorporation, the Company's By-laws or by statute. In the event of any change after the date of this Agreement in any applicable law, statute or rule which expands the rights of the corporation to indemnify a member of its board of directors or an officer, employee, agent or fiduciary, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits afforded by such change. In the event of any change in any applicable law, statute or rule which narrows the rights of this Company to indemnify a member of its board of directors or an officer, employee, agent or fiduciary, such change, to the extent not otherwise required by such law, statute or rule to be applied to this Agreement, shall have no effect on this Agreement or the parties' rights and obligations hereunder. (b) Nonexclusivity. The indemnification provided by this Agreement -------------- shall be in addition to any rights to which Indemnitee may be entitled under the Company's Certificate of Incorporation, its By-laws, any agreement, any vote of shareholders or disinterested directors, the relevant business corporation law of the Company's state of incorporation, or otherwise. The indemnification provided under this Agreement shall continue as to Indemnitee for any action taken or not taken while serving in an indemnified capacity even though Indemnitee may have ceased to serve in such capacity. 4. No Duplication of Payments. The Company shall not be liable under this --------------------------- Agreement to make any payment in connection with any action, suit, proceeding, inquiry or investigation made against Indemnitee to the extent Indemnitee has otherwise actually received payment (under any insurance policy, Certificate of Incorporation, By-laws or otherwise) of the amounts otherwise indemnifiable hereunder. 5. Partial Indemnification. If Indemnitee is entitled under any provision ------------------------ of this Agreement to indemnification by the Company for some or a portion of Expenses in the investigation, defense, appeal or settlement of any civil or criminal action, suit, proceeding, inquiry or investigation, but not, however, for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion of such Expenses to which Indemnitee is entitled. 6. Mutual Acknowledgment. Both the Company and Indemnitee acknowledge that --------------------- in certain instances, Federal law or applicable public policy may prohibit the Company from indemnifying its directors, officers, employees, agents or fiduciaries under this Agreement or otherwise. Indemnitee understands and acknowledges that the Company has undertaken or may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Company's right under public policy to indemnify Indemnitee. -5-

7. Liability Insurance. To the extent the Company maintains liability -------------------- insurance applicable to directors, officers, employees, agents or fiduciaries, Indemnitee shall be covered by such policies in such a manner as to provide Indemnitee the same rights and benefits as are accorded to the most favorably insured of the Company's directors, if Indemnitee is a director; or of the Company's officers, if Indemnitee is not a director of the Company but is an officer; or of the Company's key employees, agents or fiduciaries, if Indemnitee is not an officer or director but is a key employee, agent or fiduciary. 8. Exceptions. Any other provision herein to the contrary notwithstanding, ---------- the Company shall not be obligated pursuant to the terms of this Agreement: (a) Excluded Action or Omissions. To indemnify Indemnitee for acts, ----------------------------- omissions or transactions from which Indemnitee may not be relieved of liability under applicable law. (b) Claims Initiated by Indemnitee. To indemnify or advance expenses ------------------------------- to Indemnitee with respect to proceedings or claims initiated or brought voluntarily by Indemnitee and not by way of defense, except (i) with respect to proceedings brought to establish or enforce a right to indemnification under this Agreement or any other agreement or insurance policy or under the Company's Certificate of Incorporation or By-laws now or hereafter in effect relating to Claims for Indemnifiable Events, (ii) in specific cases if the Board of Directors has approved the initiation or bringing of such suit, or (iii) as otherwise required under the applicable provisions of the business corporation law of the Company's state of incorporation, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advance expense payment or insurance recovery, as the case may be. (c) Lack of Good Faith. To indemnify Indemnitee for any expenses ------------------- incurred by the Indemnitee with respect to any proceeding instituted by Indemnitee to enforce or interpret this Agreement, if a court of competent jurisdiction determines that each of the material assertions made by the Indemnitee in such proceeding was not made in good faith or was frivolous; or (d) Claims Under Section 16(b). To indemnify Indemnitee for expenses -------------------------- and the payment of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or any similar successor statute. 9. Period of Limitations. No legal action shall be brought and no cause of --------------------- action shall be asserted by or in the right of the Company against Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal representatives after the expiration of two (2) years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by the timely filing of a legal action within such two (2)-year period; provided, however, that if any -------- ------- shorter period of limitations is otherwise applicable to any such cause of action, such shorter period shall govern. -6-

10. Construction of Certain Phrases. ------------------------------- (a) For purposes of this Agreement, references to the "Company" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, employees, agents or fiduciaries, so that if Indemnitee is or was a director, officer, employee, agent or fiduciary of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee, agent or fiduciary of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, Indemnitee shall stand in the same position under the provisions of this Agreement with respect to the resulting or surviving corporation as Indemnitee would have with respect to such constituent corporation if its separate existence had continued.

(c) For purposes of this Agreement a "Change in Control" shall be deemed to have occurred if (i) any "person" (as such term is used in Sections 13(d) and 14(d) of the Exchange Act), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned directly or indirectly by the shareholders of the Company in substantially the same proportions as their ownership of stock of the Company, is or becomes the "beneficial owner" (as determined in accordance with Rule 13d-3 under said Exchange Act), directly or indirectly, of securities of the Company representing more than twenty percent (20%) of the total voting power represented by the Company's then outstanding Voting Securities, (ii) during any period of two (2) consecutive years, individuals who at the beginning of such period constitute the Board of Directors of the Company and any new director whose election by the Board of Directors or nomination for election by the Company's shareholders was approved by a vote of at least two thirds (2/3) of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof, or (iii) the shareholders of the Company approve a merger or consolidation of the Company with any other corporation other than a merger or consolidation which would result in the Voting Securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into Voting Securities of the surviving entity) at least 80% of the total voting power represented by the Voting Securities of the Company or such surviving -7-

entity outstanding immediately after such merger or consolidation, or the shareholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of (in one transaction or a series of transactions) all or substantially all of the Company's assets. (d) For purposes of this Agreement, "Independent Legal Counsel" shall mean an attorney or firm of attorneys, selected in accordance with the provisions of Section 1(c) hereof, who shall not have otherwise performed services for the Company or Indemnitee within the last three years (other than with respect to matters concerning the rights of Indemnitee under this Agreement, or of other indemnitees under similar indemnity agreements). (e) For purposes of this Agreement, a "Reviewing Party" shall mean any appropriate person or body consisting of a member or members of the Company's Board of Directors or any other person or body appointed by the Board of Directors who is not a party to the particular Claim for which Indemnitee is seeking indemnification, or Independent Legal Counsel.

This Agreement may be executed in one or more ------------ counterparts, each of which shall constitute an original. 12. Binding Effect; Successors and Assigns.

The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. This Agreement shall continue in effect regardless of whether Indemnitee continues to serve as a director of the Company or of any other enterprise at the Company's request. 13. Attorneys' Fees. In the event that any action is instituted by ---------------- Indemnitee under this Agreement or under any liability insurance policies maintained by the Company to enforce or interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be paid all Expenses incurred by Indemnitee with respect to such action, regardless of whether Indemnitee is ultimately successful in such action, and shall be entitled to the advancement of Expenses with respect to such action, unless as a part of such action the court of competent jurisdiction over such action determines that each of the material assertions made by Indemnitee as a basis for such action were not made in good faith or were frivolous. In the event of an action instituted by or in the name of -8-

the Company under this Agreement to enforce or interpret any of the terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses incurred by Indemnitee in defense of such action (including costs and expenses incurred with respect to Indemnitee's counterclaims and cross-claims made in such action), and shall be entitled to the advancement Expenses with respect to such action, unless as a part of such action the court having jurisdiction over such action determines that each of Indemnitee's material defenses to such action were made in bad faith or were frivolous. 14.
