The Parties expressly waive and relinquish all rights and benefits under that section and any similar statute or common law principle of similar effect of any state or territory of the United States with respect to the claims released hereby. Section 1542 reads as follows: GENERAL RELEASE - CLAIMS EXTINGUISHED. "A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor." 13. The Parties warrant and represent that there are no liens or claims of lien or assignments at law, in equity or otherwise, of or against any of the claims or causes of action released herein and, further that they are fully entitled and duly authorized to give this complete and final general release and discharge. 14. The Parties hereby agree and acknowledge that they will keep the terms and amounts of this Agreement completely confidential, and that neither party will hereafter disclose or publicize such terms or amounts of the Agreement in any manner whatsoever; provided however that: (a) the Parties may disclose this Agreement, in confidence, to their respective attorneys, accountants, auditors, tax preparers, and financial advisors; (b) the Parties may disclose this Agreement as necessary to fulfill standard or legally required corporate reporting or disclosure requirements; and (c) the Parties may disclose this Agreement insofar as such disclosure may be necessary to enforce its terms or as otherwise required by law. 15. The Parties shall execute and cause to be delivered to each other party hereto such instruments and other documents, and shall take such other actions, as reasonably necessary for the purpose of carrying out or evidencing any of the transactions contemplated by this Agreement. 16. This Agreement contains the entire agreement between the Parties and constitutes the complete, final and exclusive embodiment of their agreement with respect to the subject matter hereof, and all prior or contemporaneous agreements, understandings, representations and statements, oral or written, are merged into and superseded by this Agreement. This Agreement may not be modified except in a writing signed by the Parties. Each party acknowledges and agrees that they have carefully read this Agreement, and have been afforded the opportunity to be advised of its meaning and consequences by their respective attorneys, and signed the same of their free will. 17. Each party to this Agreement will bear its own costs, expenses, and attorneys' fees, whether taxable or otherwise, incurred in or arising out of or in any way related to the matters released herein, except that VGI will bear the shipping costs associated with the deliveries to be made by Corvas pursuant to Section 2 and 3 herein, including all insurance costs associated therewith. 18. This Agreement shall be deemed to be entered into and shall be construed and enforced in accordance with the laws of the State of California as applied to contracts made and to be performed entirely in California; it shall be interpreted and construed mutually in accordance with the plain meaning of the language contained herein and shall not be preemptively construed against the drafters. 19. If any term or provision of this Agreement is held by any court to be void, invalid or unenforceable, in whole or in part, then the remaining terms and provisions shall nevertheless remain in full force and effect. 20. Venue for any action to enforce or interpret this Agreement or otherwise arising out of or in any way related to this Agreement shall be the California Superior Court, County of San Diego. 21. In the event that any party to this Agreement brings an action to enforce any of the terms of this Agreement, the prevailing party in such action shall be entitled to an award of attorneys' fees and costs incurred in connection therewith. 22. Whenever the text hereof requires, the use of the singular shall include the plural and vice-versa. 23.

VGI is not in violation or default of any term of the VGI Certificate of Incorporation or Bylaws, or of any provision of any mortgage, indenture, contract, agreement, instrument or contract to which it is party or by which it is bound or of any judgment, decree, order, writ. The execution, delivery, and performance of and compliance with this Agreement, and the issuance and sale of the Shares pursuant hereto, will not, with or without the passage of time or giving of notice, result in any such material violation, or be in conflict with or constitute a default under any such term, or result in the creation of any mortgage, pledge, lien, encumbrance or charge upon any of the properties or assets of VGI or the suspension, revocation, impairment, forfeiture or nonrenewal of any permit, license, authorization or approval applicable to VGI, its business or operations or any of its assets or properties. 1.18 GOVERNMENTAL CONSENT, ETC. No consent, approval or authorization of or designation, declaration or filing with any governmental authority on the part of VGI or the VGI Stockholders is required in connection with the valid execution and delivery of this Agreement, or the offer and sale of the VGI Shares by the VGI Stockholders or the consummation of any other transaction contemplated thereby. 1.19 SALE. Subject to the accuracy of the representations set forth in Section 3 hereof, the offer and sale of the VGI Shares pursuant to this Agreement (i) constitute transactions exempt from the registration requirements of Section 5 of the Securities Act and (ii) is in compliance with all applicable state securities laws. 1.20 OWNERSHIP.

VGI and the VGI Stockholders have not incurred, and will not incur, any liability for brokerage or finders' fees or agents' commissions or any similar charges in connection with the Agreement. 7. 1.23 INVESTMENT REPRESENTATIONS. Each VGI Stockholder understands that the Shares have not been registered under the Securities Act. Each VGI Stockholder also understands that the Shares are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in part upon his or her representations contained in this Agreement. Each VGI Stockholder hereby represents and warrants as follows: (a) THE VGI STOCKHOLDER BEARS ECONOMIC RISK. The VGI Stockholder has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. The VGI Stockholder must bear the economic risk of this investment indefinitely unless the Shares are registered pursuant to the Securities Act, or an exemption from registration is available. The VGI Stockholder understands that the Company has no present intention of registering the Shares, or any shares of its Common Stock. The VGI Stockholder also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow the VGI Stockholder to transfer all or any portion of the Shares under the circumstances, in the amounts or at the times the VGI Stockholder might propose. (b) ACQUISITION FOR OWN ACCOUNT. The VGI Stockholder is acquiring the Shares for the VGI Stockholder's own account for investment only, and not with a view towards their distribution. (c) THE VGI STOCKHOLDER CAN PROTECT ITS INTEREST. The VGI Stockholder represents that by reason of its, or of its management's, business or financial experience, the VGI Stockholder has the capacity to protect his or her own interests in connection with the transactions contemplated in this Agreement. Further, the VGI Stockholder is aware of no publication of any advertisement in connection with the transactions contemplated in this Agreement. (d) ACCREDITED INVESTOR. The VGI Stockholder represents that he or she is an accredited investor within the meaning of Regulation D under the Securities Act. (e) COMPANY INFORMATION. The VGI Stockholder has received and read the Company's Annual Report on Form 10-K for the period ended December 31, 1998 and the Quarterly Report on Form 10-Q for the quarter ended March 31, 1999, and a description of the capital stock of the Company and has had an opportunity to discuss the Company's business, management and financial affairs with directors, officers and management of the Company and has had the opportunity to review the Company's operations and facilities. The VGI Stockholder has also had the opportunity to ask questions of and receive answers from, the Company and its management regarding the terms and conditions of this investment. (f) RULE 144. The VGI Stockholder acknowledges and agrees that the Shares must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. The VGI Stockholder has been advised or is aware of the provisions of Rule 144 promulgated under the Securities Act as in effect from time to time, which 8. permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the Company, the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month period not exceeding specified limitations. (g) RESIDENCE. The VGI Stockholder resides in the state or province identified in the address of such VGI Stockholder set forth on EXHIBIT A. (h) TRANSFER RESTRICTIONS. Each VGI Stockholder acknowledges and agrees that the Shares are subject to restrictions on transfer as set forth in this Agreement. COMPANY REGISTRATION; RESTRICTIONS ON TRANSFER 1.24 RESTRICTIONS ON TRANSFER. (a) Each VGI Stockholder agrees not to make any disposition of all or any portion of the Shares or Registrable Securities unless and until: (i) There is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or (ii) (A) The transferee has agreed in writing to be bound by the terms of this Agreement, (B) such VGI Stockholder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and (C) if reasonably requested by the Company, such VGI Stockholder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Securities Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances. (b) Each certificate representing Shares or Registrable Securities shall (unless otherwise permitted by the provisions of the Agreement) be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws): THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED. (c) The Company shall be obligated to reissue promptly unlegended certificates at the request of any VGI Stockholder thereof if the VGI Stockholder shall have obtained an opinion of counsel (which counsel may be 9. counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be so disposed of without registration, qualification or legend. (d) Any legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with respect to such securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal. 1.25 FORM S-3 REGISTRATION. Within 30 days after the effective date of the Settlement Agreement, the Company will file a registration on Form S-3 (or any successor to Form S-3) or any similar short-form registration statement and any related qualification or compliance under the Securities Act (the "Registration Statement") with respect to all of the Registrable Securities owned by the VGI Stockholders. The Company agrees to use its reasonable best efforts to cause the Registration Statement to be declared effective by the SEC as soon as practicable following filing thereof and thereafter to maintain the effectiveness of the Registration Statement until the earlier of (i) all Registrable Securities have been sold pursuant to the Registration Statement or (ii) one (1) year from the effective date of the Registration Statement. 1.26 EXPENSES OF REGISTRATION. The Company shall pay all Registration Expenses. 1.27 OBLIGATIONS OF THE COMPANY. Whenever required to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: (a) 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 for the period set forth in Section 5.2 above. (b) Furnish to the VGI Stockholders such number 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. (c) Use its reasonable 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 VGI Stockholders; 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. (d) Notify each VGI Stockholder 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. 10. 1.28 INFORMATION AND LIMITATIONS ON DISTRIBUTIONS. As a condition to effecting the registration of any Registrable Securities pursuant to Section 5.2 and maintaining its effectiveness, the Company may require each selling VGI Stockholder of Registrable Securities as to which any registration is being effected to furnish to the Company such information regarding the distribution of such securities as the Company may from time to time reasonably request in writing. Notwithstanding any other provision of this Agreement, prior to and following the effectiveness of any Registration Statement filed pursuant to Section 5.2 hereunder, the Company may, at any time, suspend the filing of or the effectiveness of such Registration Statement for up to no longer than forty-five (45) days, as appropriate (a "SUSPENSION PERIOD"), by delivering a signed certificate of the Company's Chairman of the Board to the VGI Stockholder that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its Stockholders to disclose any previously undisclosed material corporate development that would be required to be disclosed if the Registration Statement is not suspended. The Company will use its best efforts to minimize the length of any Suspension Period. The VGI Stockholder agrees that, upon the receipt of any notice from the Company of a Suspension Period, the VGI Stockholder will not sell any Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until (i) the VGI Stockholder is advised in writing by the Company that the use of the applicable prospectus may be resumed, (ii) the VGI Stockholder has received copies of any additional, supplemental or amended prospectus, if applicable, and (iii) the VGI Stockholder has received copies of any additional or supplemental filings which are incorporated or deemed to be incorporated by reference in such prospectus. 1.29 INDEMNIFICATION. In the event any Registrable Securities are included in a Registration Statement under Section 5.2: (a) To the extent permitted by law, the Company will indemnify and hold harmless each VGI Stockholder, the partners, officers and directors of each VGI Stockholder, any underwriter (as defined in the Securities Act) for such VGI Stockholder and each person, if any, who controls such VGI Stockholder or underwriter within the meaning of the Securities Act or 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, 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") by the Company: (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 in connection with the offering covered by such Registration Statement; and the Company will pay as incurred to each such VGI Stockholder, partner, officer, director, 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 Section 5.6(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action 11. if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, 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 such VGI Stockholder, partner, officer, director, underwriter or controlling person of such VGI Stockholder. (b) To the extent permitted by law, each VGI Stockholder will, if Registrable Securities held by such VGI Stockholder are included in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other VGI Stockholder selling securities under such Registration Statement or any of such other VGI Stockholder's partners, directors or officers or any person who controls such VGI Stockholder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such VGI Stockholder, or partner, director, officer or controlling person of such other VGI Stockholder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as 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 VGI Stockholder under an instrument duly executed by such VGI Stockholder and stated to be specifically for use in connection with such registration; and each such VGI Stockholder will pay as incurred any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other VGI Stockholder, or partner, officer, director or controlling person of such other VGI Stockholder in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Violation; PROVIDED, HOWEVER, that the indemnity agreement contained in this Section 5.6(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 VGI Stockholder, which consent shall not be unreasonably withheld; PROVIDED FURTHER, that in no event shall any indemnity under this Section 5.6 exceed the net proceeds from the offering received by such VGI Stockholder. (c) Promptly after receipt by an indemnified party under this Section 5.6 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 5.6, 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 differing interests between such indemnified 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 materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to 12. the indemnified party under this Section 5.6, 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 indemnified party otherwise than under this Section 5.6. (d) If the indemnification provided for in this Section 5.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability 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 in connection with the Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; PROVIDED, that in no event shall any contribution by a VGI Stockholder hereunder exceed the net proceeds from the offering received by such VGI Stockholder. (e) The obligations of the Company and VGI Stockholders under this Section 5.6 shall survive completion of any offering of Registrable Securities in a Registration Statement and the termination of this agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. 1.30 COVENANT REGARDING SALE OF SECURITIES. Each VGI Stockholder hereby acknowledges and agrees that the disorderly resale of the Shares in the public market may adversely effect the market price of the Company's Common Stock. In consideration of the covenants set forth in this Agreement and the payments made under the Settlement Agreement, each of the VGI Stockholders hereby covenants that neither such VGI Stockholder nor any combination of VGI Stockholders shall sell, within any three month period, a total number of the Shares and other shares of Company's Common Stock owned or controlled by such VGI Stockholders in excess of the greater of (i) one percent of the total outstanding shares of Common Stock of the Company as shown by the most recent report or statement published by the Company, or (ii) the average weekly reported volume of trading in the Company's Common Stock on the Nasdaq National Market or such exchange or market in which the Company's Common Stock is then traded or quoted during the four calendar weeks preceding the proposed sale. All shares of Company Common Stock sold by any of the VGI Stockholders during any period of three months shall be aggregated for the purpose of determining the limitation on the amount of securities sold. 13. 1.31 RULE 144 REPORTING. With a view to making available to the VGI Stockholders the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to: (a) Make and keep public information available, as those terms are understood and defined in SEC Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public; (b) File with the SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and (c) So long as a VGI Stockholder owns any Registrable Securities, furnish to such VGI Stockholder forthwith upon request: a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual or quarterly report of the Company; and such other reports and documents as a VGI Stockholder may reasonably request in availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration. VGI REGISTRATION; RESTRICTIONS ON TRANSFER 1.32 REGISTRATION RIGHTS. VGI agrees to grant to the Company on a pari passu basis any current or future registration rights that have been granted or shall be granted in the future to the VGI Stockholders with respect to capital stock of VGI owned by the VGI Stockholders as. of the date of this Agreement. VGI shall take all necessary steps to include the Company as a party to any such existing agreement and further agreeing to include the Company as a party to any agreement in the future that shall grant to the VGI Stockholders any registration rights. 1.33 RESTRICTIONS ON TRANSFER.

It is agreed that VGI will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances. (iii) Notwithstanding the provisions of paragraphs (i) and (ii) above, no such registration statement or opinion of counsel shall be necessary for a transfer by the Company which is (A) a partnership to its partners or former partners in accordance with partnership interests, (B) a 14. corporation to its stockholders in accordance with their interest in the corporation, or (C) a limited liability company to its members or former members in accordance with their interest in the limited liability company; PROVIDED that in each case the transferee will be subject to the terms of this Agreement to the same extent as if he were an original party hereunder. (b) Each certificate representing the VGI Shares shall (unless otherwise permitted by the provisions of the Agreement) be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws): THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS VASCULAR GENOMICS, INC.

(c) VGI shall be obligated to reissue promptly unlegended certificates at the request of the Company if the Company shall have obtained an opinion of counsel (which counsel may be counsel to VGI) reasonably acceptable to VGI to the effect that the securities proposed to be disposed of may lawfully be so disposed of without registration, qualification or legend.
