Biro (the "Representative"), and The First National Bank of Boston ("Escrow Holder"). BACKGROUND A. Pursuant to an Agreement and Plan of Reorganization and Merger (the "Merger Agreement") dated as of July 18, 1995, among OXIS, OXIS Acquisition Corporation, a Delaware corporation ("OXISub"), and Therox Pharmaceuticals, Inc., a Delaware corporation ("Therox"), Therox will be merged with and into OXISub and OXISub will continue to be the surviving corporation and a wholly- owned subsidiary of OXIS (the "Merger"). B. This Escrow Agreement is being entered into pursuant to Section 2.6 and Article 9 of the Merger Agreement. Execution and delivery of this Escrow Agreement is a condition to the obligations of the parties to the Merger Agreement to consummate the Merger. C.

D. Pursuant to the Merger Agreement, the shares of the common and preferred stock of Therox that are outstanding immediately prior to the effective time of the Merger, other than dissenting shares, will be converted into shares of the common stock, par value $0.50 per share, of OXIS ("OXIS Common"). E. Section 2.6 of the Merger Agreement provides that at the effective time of the Merger, certain of the shares of the common stock of OXIS issued in the Merger shall be delivered on - 44 - behalf of the Former Shareholders to the Escrow Holder in order to secure the indemnification obligations of Therox and the Former Shareholders set forth in Article 9 of the Merger Agreement. NOW, THEREFORE, in consideration of the entering into of the Merger Agreement, the parties agree as follows: ARTICLE 1 DEFINITIONS ----------- Unless otherwise defined herein, capitalized terms used herein shall have the meanings set forth in the Merger Agreement. In addition, for the purposes of this Escrow Agreement, the following terms shall have the following meanings: 1.1 Claim Certificate.

"Damages" shall mean any and all losses, damages, ------- liabilities, claims, judgments, settlements, costs and expenses (including reasonable attorneys' fees) of the type referred to in Article 9 of the Merger Agreement. 1.3 Escrow Fund. "Escrow Fund" shall mean the Escrowed Shares then held ----------- by the Escrow Holder. 1.4 Escrowed Share. An "Escrowed Share" shall mean a share of OXIS Common -------------- delivered to the Escrow Holder by the Exchange Agent on behalf of the Former Shareholders in accordance with Section 2.6 of the Merger Agreement, together with any and all other shares of OXIS Common, other securities of OXIS or any other issuer, other property or cash received or receivable in respect of such share of OXIS Common, including, without limitation, any and all securities, property or cash to be issued - 45 - or distributed in connection with any recapitalization, reclassification, split- up, merger, consolidation, exchange, stock dividend, stock split or similar event declared or effected with respect to shares of OXIS Common. 1.5 Indemnified Person. "Indemnified Person" shall mean OXIS and any ------------------ other entity or person who is a beneficiary of the indemnification obligations of Therox contained in Article 9 of the Merger Agreement. 1.6 Value. "Value" when used with respect to an Escrowed Share, shall ----- mean the average closing bid price of the OXIS common stock on the Nasdaq National Market for the ten trading days immediately preceding the Effective Time as defined in the Merger Agreement as reported in The Wall Street Journal, ----------------------- as adjusted for stock splits, stock dividends, recapitalizations and the like. ARTICLE 2 CREATION OF ESCROW ------------------ 2.1 Purpose. This Escrow Agreement is being executed and delivered, and ------- the deposit of the Escrow Fund hereunder is being made, for the purpose of securing the indemnification obligations of Therox and the Former Shareholders set forth in Article 9 of the Merger Agreement. 2.2 Creation of Escrow Fund. At or promptly after the Effective Time, the ----------------------- Representative shall instruct the Exchange Agent to deposit with the Escrow Holder certificates representing those shares of OXIS Common required to be so deposited under Section 2.6 of the Merger Agreement registered in the names of the Former Shareholders. OXIS and the Former Shareholders agree that any other securities, property or cash which thereafter are to become part of the Escrow Fund as provided in Section 1.4 of this Escrow Agreement, shall be promptly deposited with the Escrow Holder upon receipt by or on behalf of the Former Shareholders, and receipt by the Escrow Holder on behalf of the Former Shareholders shall be deemed receipt by the Former Shareholders. Certificates representing securities deposited in the Escrow Fund shall be accompanied by separate stock powers endorsed in blank by the Representative on behalf of the Former Shareholders. - 46 - 2.3 Voting Rights. The Former Shareholders shall retain their voting ------------- rights with respect to securities held by the Escrow Holder unless and until such securities are delivered by the Escrow Holder to OXIS in accordance with this Escrow Agreement. 2.4 Dividends.

Unless, within 60 days after the giving -------------------------- of any Claim Certificate by OXIS, OXIS and the Escrow Holder receive a written notice from the Representative stating that the Representative questions the accuracy of a matter asserted in such Claim Certificate, such Claim Certificate shall constitute full authority to the Escrow Holder to take the action provided for in Section 3.1 and shall be conclusive and binding on all parties hereto and on the Former Shareholders. If, however, the Representative timely gives such a notice, the Escrow Holder shall not make any distribution to OXIS of that portion of the Escrow Fund which the Representative asserts in his notice should not be so distributed until (i) the Escrow Holder receives the written consent of the Representative and OXIS to such distribution or (ii) there is a final decision of an arbitrator in an action between OXIS and the Representative with - 47 - respect to the disputed amount pursuant to Section 7.7 hereof. The reasonable expenses, including attorneys' fees, of all of the parties to any such arbitration, or any lawsuit or other proceeding arising hereunder, shall be reasonably apportioned among them, taking into consideration the outcome of the arbitration, lawsuit or other proceeding and the reasonableness of the conduct of each such party in connection with the dispute over the disposition of that portion of the Escrow Fund which was in controversy, in light of the facts known to such party at the time such party engaged in such conduct. Any and all amounts payable to OXIS or any other Indemnified Person pursuant to the preceding sentence shall be paid out of the Escrow Fund as though it were an item of Damages. 3.3 Notice and Defense of Third Party Claims. No later than 15 days after ---------------------------------------- receipt by OXIS of a written notice of any action, suit or proceeding commenced against OXIS or the Company which might be a basis for indemnification under Article 9 of the Merger Agreement, OXIS will give the Representative written notice thereof and will afford them an opportunity to defend such action, suit or proceeding on behalf of the Former Shareholders, at the expense of the Representative or the Former Shareholders; provided however, that OXIS may participate in the control of such defense if the Representative and Former Shareholders do not diligently defend such action, suit or proceeding. ARTICLE 4 DISTRIBUTION OF ESCROW FUND --------------------------- 4.1 Distribution of Undisputed Amounts. ---------------------------------- A. Provided that there are no outstanding claims pursuant to Article 3 hereof, on the date twelve months after the date of this Escrow Agreement, the Escrow Holder shall promptly distribute one-third (1/3) of the Escrow Fund to the Representative for the benefit of the Former Shareholders, or to the Former Shareholders, as the Representative shall direct in writing, such written direction to include the calculation of the pro rata distribution according to the number of shares of Therox Common and Therox Preferred held by the Former Shareholders at the Effective Time.

Investor further acknowledges and understands that the Company may require Investor to provide the Company with additional information to verify Investor's "accredited investor" status. 2. Investment Purposes. ------------------- (i) Purchase by Principal Without View To Distribution. By its -------------------------------------------------- execution of this Investment Representation Letter investor hereby represents and confirms that the Securities acquired by Investor are acquired for investment for its own account, not as nominee or agent, and not with a view to, and not in connection with, the distribution of any part thereof, and that Investor has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Investment Representation Letter, Investor further represents that Investor does not have any agreement or arrangement with any person to sell or transfer the Securities to such person or any third person and that no person other than Investor will have any beneficial interest in the Securities (except that Investor's spouse may have a beneficial interest in the Securities). (ii) Non-Registration. Investor acknowledges and understands that the ---------------- Securities have not been registered under the Act, or registered or qualified under the laws of any state, on the grounds that the offering and sale of Securities contemplated by this Investment Representation Letter are exempt from registration and qualification pursuant to Section 4(2) of the Act and/or Regulation D promulgated under the Act and comparable state laws, and that the Company's reliance upon such exemptions is predicated upon the representations of Investor set forth in this Investment Representation Letter. Investor further acknowledges and understands that the Securities must be held indefinitely unless the Securities are subsequently registered under the Act and registered or qualified under any applicable state law or an exemption from such registration and qualification is available. Investor further acknowledges and understands that the Company is under no obligation to register or qualify the Securities other than as set forth in the Registration Rights Agreement between the Company and Investor, dated as of the date hereof. -64- 3. Transfer Restrictions Under Securities Laws. Investor hereby ------------------------------------------- acknowledges that no transfer of the Securities may be made except as permitted by applicable federal and state Securities laws. The Investor is aware of the adoption of Rule 144 by the SEC, which permits limited public resale of securities acquired in a nonpublic offering subject to the satisfaction of certain conditions, including among other things, the availability of certain current public information about the Company, the resale occurring not less than two years after the party has purchased and paid for the securities to be sold, the sale being through a broker in an unsolicited "broker's transaction" and the amount of securities being sold during any three-month period not exceeding specified limitations (generally one percent (1%) of the total amount outstanding or the average weekly trading volume of the securities during the four calendar weeks preceding the sale). The Investor further acknowledges and understands that the Company may not be satisfying the current public information requirement of Rule 144 (notwithstanding any contractual commitment of the Company to do so) at the time the undersigned wishes to sell the Securities. If such requirement is not satisfied, the Investor would be precluded from selling the Securities under Rule 144 even if the two-year minimum holding period has been satisfied, unless at the time the Investor wishes to sell the Securities, the Investor has held the Securities for not less than three years and the Investor is not an affiliate of the Company (as defined in Rule 144) and has not been an affiliate for the preceding three months. The Investor further acknowledges that in the event all of the requirements of Rule 144 are not met, compliance with Regulation A or some other registration exemption will be required; and that although Rule 144 is not exclusive, the staff of the SEC has expressed its opinion that shareholders proposing to sell private placement securities other than in a registered offering and other than pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such shareholders and the brokers who participate in the transactions do so at their own risk. 4. Capacity to Sign. Investor covenants that it possesses all necessary ---------------- capacity and authority to sign and make the representations contained in this Investment Representation Letter. Each individual signing this Investment Representation Letter in the capacity of trustee, guardian, conservator, or in any other legal capacity, covenants that he has the necessary capacity and authority to act for, sign, and bind the respective entity or principal on whose behalf he is signing. 5. Receipt of Disclosure Information. Investor acknowledges that it has --------------------------------- received, read, understands, and is familiar with Company's Annual Report on Form 10-K for the period ending December 31, 1994, Quarterly Report on Form 10-Q for the period ending March 31, 1995 and Report on Form 8-K dated May 17, 1995 (collectively, the "'34 Act Reports"). Investor further acknowledges that, except as set forth in this Investment Representation Letter and the Agreement and Plan of Reorganization and Merger ("Reorganization Agreement") between the Company, OXIS Acquisition Corporation, a Delaware corporation and the wholly- owned subsidiary of the Company, and Therox Pharmaceuticals, Inc., a Delaware corporation dated as -65- of July 18, 1995, no representations and warranties have been made to it, or to its advisors, by the Company, or by any person acting on behalf of the Company, and that it has not relied upon any information concerning the Company, written or oral, other than that contained in this Investment Representation Letter, the Reorganization Agreement, the '34 Act Reports or otherwise conveyed in writing by the Company to the Investor. Investor understands that an investment in the Company presents a high degree of risk and Investor represents that it is able to bear the entire loss of its investment in the Company. 6. Miscellaneous. Investor further represents and warrants to the ------------- Company as follows: (i) Investor has been furnished with, or has been given reasonable access to, disclosure of such information as it has considered necessary to make a determination as to the purchase of the Securities, including all material contracts and documents relating to the proposed transaction and information with respect to the character, business acumen and general business and financial circumstances of the Company, together with such additional information as is necessary to verify the accuracy of the information supplied; (ii) the Company has made available to Investor at a reasonable time prior to the purchase of the Securities the opportunity to ask questions to and receive answers from the Company concerning the terms and conditions of the offering of the Securities and Investor has had all questions which have been asked by it satisfactorily answered by the Company; (iii) Investor has not been offered Securities by any form of general solicitation or general advertising, including but not limited to any advertisement, article, notice or other communication published by any newspaper, magazine or similar media or broadcast over television or radio, or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising; (iv) Investor is capable of evaluating the risks and merits of an investment in the Company and can bear the economic risk (and possible loss) of its investment in the Company; and (v) Investor certifies under penalty of perjury that it is not subject to backup withholding either because it has not been notified that it is subject to backup withholding as a result of a failure to report all interest or dividends, or the Internal Revenue Service has notified Investor that it is no longer subject to backup withholding (if Investor has been notified that it is currently subject to backup withholding, Investor has stricken the language under Section 6(iv) above before signing). 7. Legends on Securities. The Securities shall be endorsed with the --------------------- following legend: -66- "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO OR IN CONNECTION WITH THE DISTRIBUTION THEREOF. NO SUCH DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933." and any other legend required by Federal law or applicable blue sky laws of any state. 8.

Attached hereto as Schedule A is a complete list of the ---------- Shareholders and the Registrable Securities held by each such Shareholder. RECITALS: -------- WHEREAS, in connection with (i) the merger of its wholly-owned subsidiary with Therox Pharmaceuticals, Inc., a Delaware corporation ("Therox") and (ii) the simultaneous offering of the Company's Series B Preferred Stock to certain investors, the Company has issued shares of its Common Stock and Series B Preferred Stock to such former Therox shareholders and such investors and pursuant to the terms of this Agreement is agreeing to register the resale of such shares of Company Common Stock and Common Stock issuable upon conversion of such Series B Preferred Stock with the Securities and Exchange Commission (the "SEC"); NOW, THEREFORE, the parties hereto hereby agree as follows: 1. Registration Rights. The Company covenants and agrees as follows: ------------------- 1.1 Definitions. For purposes of this Section 1: ----------- (a) The terms "register," "registered," and "registration" refer to a registration effected by preparing and filing a registration statement or similar document in compliance with the Securities Act of 1933, as amended (the "Securities Act"), and the declaration or ordering of effectiveness of such registration statement or document. (b) The term "Registrable Securities" means (i) any Common Stock of the Company ("Common Stock") currently outstanding issued to former shareholders of Therox pursuant to the Agreement and Plan of Reorganization and Merger (the "Merger -69- Agreement"), dated as of July 18, 1995 between the Company, the Company's subsidiary, and Therox, (ii) any Common Stock issuable upon conversion of the Series B Preferred Stock of the Company issued to certain investors pursuant to a Series B Preferred Stock Purchase Agreement dated July 18, 1995 between the Company and such investors (the "Stock Purchase Agreement") (the Merger Agreement and the Stock Purchase Agreement are hereafter sometimes collectively referred to as the "Acquisition Agreements"), and (iii) any Common Stock issued or issuable as a dividend or other distribution with respect to, or in exchange for or in replacement of, such Registrable Securities, excluding in all cases, however, any Registrable Securities sold by a person in a transaction in which his or her registration rights are not assigned. (c) The term "Holder" means any person owning or having the right to acquire Registrable Securities or any assignee thereof in accordance with Section 1.8 hereof. 1.2 Registration. ------------ (a) The Company shall file, and use its best efforts to cause the SEC to declare effective, on or before July 18, 1996, a registration statement under the Securities Act covering the resale of the Registrable Securities by the Holders. In the event that the Company grants new registration rights in connection with an issuance and sale of capital stock taking place after the date of this Agreement which results in the Company filing prior to July 18, 1996 a registration statement covering the resale of such capital stock, the Holders of Registrable Securities hereunder shall be entitled to have their Registrable Securities registered on such registration statement upon the terms and conditions set forth herein. In such event, the Company shall have no obligation to file the registration statement contemplated by the first sentence of this Section 1.2(a). (b) Notwithstanding the foregoing, the Company shall not be obligated to take any action to effect any such registration pursuant to this Section 1.2 in any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act. -70- 1.3 Obligations of the Company. The Company shall: -------------------------- (a) Keep the registration statement with respect to the Registrable Securities filed pursuant to Section 1.2 of this Agreement ("Registration Statement") effective for the period from the date of declaration of effectiveness of such Registration Statement through July 18, 1997. (b) Prepare and file with the SEC such amendments and supplements to such Registration Statement and the prospectus used in connection with such Registration Statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the period of its effectiveness. (c) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. (d) Use its best efforts to register and qualify the securities covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions. (e) Notify each Holder of Registrable Securities covered by such Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. 1.4 Limitations on Resales. ---------------------- (a) Each Holder shall not sell during (i) any three month period while the Registration Statement is in effect, a number of shares of Registrable Securities that is greater than one percent (1%) of the number of issued and outstanding Common -71- Stock at such time and (ii) any single month while the Registration Statement is in effect, a number of shares of Registrable Securities that is more than one-third (1/3) of one percent (1%) of the number of issued and outstanding Common Stock at such time. The parties acknowledge that the one percent (1%) limitation set forth in the immediately preceding sentence is consistent with the limitation set forth in SEC Rule 144(e)(1)(i). If at any time the Company's securities trading volume as calculated pursuant to SEC Rule 144 (e)(1)(ii) (the "Company's Trading Volume Calculation") exceeds the one percent (1%) calculation, then the Holders shall be limited to an amount equal to the Company's Trading Volume Calculation instead of the one percent (1%) calculation. Within ten (10) days following the last day of any month in which a Holder sells Registrable Securities, the Holder shall notify the Company of the number of shares of Registrable Securities sold by such Holder. (b) If the Company proposes to register any of its stock or other securities under the Securities Act in connection with an underwritten public offering of such securities solely for cash, the Company shall, at such time, promptly give each Holder written notice of such registration, and in connection with such public offering, the Holders shall agree not to sell any of the Registrable Securities during such customary lock-up period requested by the Company's underwriters who are underwriting such public offering. The Holders shall have no right to participate in any such public offering. The Company's obligation to keep a registration statement effective for the time period set forth in Section 1.3(a) hereof shall be extended by an amount of time equal to any lock-up period applicable to the Holders. Notwithstanding the immediately preceding paragraph, S.R. One, Limited ("S.R. One") shall agree to a lock-up period in excess of ninety (90) days only if Ray R. Rogers, Anna D. Barker and Alta-Berkeley L.P. II ("Other Stockholders") have agreed not to sell during such lock-up period in excess of ninety (90) days; provided, however, S.R. One may request that the Company consent to relieving S.R. One of its obligation to abide by a lock-up period longer than ninety (90) days if S.R. One would suffer a hardship that is materially adversely different from that suffered by the Other Stockholders and relief from such obligation shall not materially impair the Company's ability to complete its underwritten offering. The Company shall not -72- unreasonably withhold the consent referred to in the immediately preceding sentence. 1.5 Furnish Information. It shall be a condition precedent to the ------------------- obligations of the Company to take any action pursuant to this Section 1 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them, and the intended method of disposition of such securities as shall be required to effect the registration of the Registrable Securities. 1.6 Indemnification. In the event any Registrable Securities are --------------- included in a registration statement under this Section 1: (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the officers, directors, partners and legal counsel of each Holder, any under writer (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended (the "Exchange Act"), against any losses, claims, damages or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, rule or regulation insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively, a "Violation"): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the 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 (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; and the Company will reimburse each such Holder, officer, director, partner, legal counsel, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the indemnity agreement contained in this subsection 1.6(a) shall not apply to amounts paid in settlement of -73- any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, officer, partner, director, underwriter, legal counsel or controlling person. (b) To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, officers, its legal counsel, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities in such Registration Statement or any of such other Holder's directors, legal counsel or officers or any person who controls such Holder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, legal counsel, controlling person, or underwriter or controlling person, or other such Holder or director, officer, legal counsel or controlling person of such other Holder may become subject, under the Securities Act, the Exchange Act or other federal or state law, to the extent that such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, legal counsel, controlling person, underwriter or controlling person, other Holder, or officer, director, legal counsel, or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this subsection 1.6(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the indemnifying Holder; provided, that, in no event shall any indemnity under this subjection 1.6(b) exceed the gross proceeds received by such Holder from the sale of Registrable Securities sold pursuant to a Registration Statement. -74- (c) Promptly after receipt by an indemnified party under this Section 1.6 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 1.6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential materially conflicting interests between such indemnifying party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 1.6, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnifying party other than under this Section 1.6. (d) If the indemnification provided for in this Section 1.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party, then each indemnifying party, in lieu of indemnifying such indemnified party thereunder, hereby agrees to contribute to the amount paid or payable by such indemnifying party in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other. Notwithstanding the foregoing, the amount any Holder of Registrable Securities shall be obligated to contribute pursuant to this Section 1.6(d) shall be limited to an amount equal to the offering price of the shares sold by such Holder pursuant to a Registration provided hereunder. (e) The obligations of the Company and Holders under this Section 1.6 shall survive the completion of any offering or sale of Registrable Securities in a Registration Statement under this Section 1, and otherwise. -75- 1.7 Reports Under Securities Exchange Act of 1934. With a view to --------------------------------------------- making available to the Holders the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration following the expiration of the effectiveness of the Registration Statement provided for hereunder, the Company agrees to use its best efforts for as long as Holders own Registrable Securities. (a) make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times; (b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. The above commitments of the Company in this Section 1.7 will continue notwithstanding a de-listing of the Company's securities from the Nasdaq National Market System. 1.8 Assignment of Registration Rights. The registration rights --------------------------------- pursuant to this Section 1 may be assigned by a Holder to a transferee or assignee who is not a competitor of the Company and acquires at least one hundred thousand (100,000) shares (as adjusted for stock splits, combinations, etc.) of Registrable Securities; provided, in each case, the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and provided, further, that such assignment shall be effective only if immediately following such transfer the further disposition of such -76- securities by the transferee or assignee is restricted under the Securities Act. If the Holder is a partnership and transfers or assigns its rights hereunder to any of its partners, such partners may aggregate the number of Registrable Securities held by them for purposes of meeting the 100,000 share threshold set forth in this Section 1.8. 1.9 Amendment of Registration Rights. Any provision of this Section -------------------------------- 1 may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the holders of at least a majority of the Registrable Securities. Any amendment or waiver effected in accordance with this Section shall be binding upon each Holder of Registrable Securities, each transferee or future holder of all such securities, and the Company. 2.
