3 AGREEMENT AND PLAN OF MERGER THIS AGREEMENT AND PLAN OF MERGER (this "AGREEMENT"), is entered into as of August 4, 2003 by and among Genzyme Corporation, a Massachusetts corporation ("PARENT"), Swift Starboard Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent ("PURCHASER"), and SangStat Medical Corporation, a Delaware corporation (the "COMPANY"). RECITALS WHEREAS, the Board of Directors of each of Parent, Purchaser and the Company has approved, and deems it advisable and in the best interests of its respective stockholders to consummate, the acquisition of the Company by Parent upon the terms and subject to the conditions set forth herein; WHEREAS, in furtherance thereof, it is proposed that (i) Purchaser commence a cash tender offer (as it may be amended from time to time as permitted by this Agreement, the "OFFER") to acquire all shares of the issued and outstanding common stock, par value $0.001 per share, of the Company, including the associated Company Rights (as defined in Section 3.2) (the "SHARES"), for $22.50 per Share, net to the seller in cash (such price, or any such higher price per Share as may be paid in the Offer, referred to herein as the "OFFER PRICE"); WHEREAS, the Board of Directors of each of Parent, Purchaser and the Company has approved this Agreement and the Transactions (as defined in Section 9.3(f)), including the Merger (as defined in Section 1.3) following the Offer in accordance with the Delaware General Corporation Law ("DGCL") and upon the terms and subject to the conditions set forth herein; WHEREAS, the Board of Directors of the Company (the "COMPANY BOARD OF DIRECTORS") has determined that the consideration to be paid for each Share in the Offer and the Merger is fair to the holders of such Shares and has resolved to recommend that the holders of such Shares accept the Offer and adopt this Agreement and each of the Transactions upon the terms and subject to the conditions set forth herein; and WHEREAS, the Company, Parent and Purchaser desire to make certain representations, warranties, covenants and agreements in connection with the Offer, the Merger and the other Transactions. NOW, THEREFORE, in consideration of the foregoing and the respective covenants, agreements, representations and warranties set forth herein, the parties agree as follows: 1 ARTICLE I THE MERGER 1.1 THE OFFER. (a) Provided that this Agreement shall not have been terminated in accordance with Section 8.1 and none of the events set forth in Annex I hereto shall have occurred, Purchaser shall commence (within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as amended (together with the rules and regulations promulgated thereunder, the "EXCHANGE ACT")), the Offer as promptly as practicable following the date hereof (but in no case later than ten (10) business days from the date hereof). The obligations of Purchaser to accept for payment and to pay for any Shares validly tendered and not withdrawn prior to the expiration of the Offer (as it may be extended in accordance with requirements of this Section 1.1(a)) shall be subject only to the conditions set forth in Annex I hereto. Subject to the prior satisfaction or waiver by Parent or Purchaser of the conditions of the Offer set forth in Annex I hereto, Purchaser shall consummate the Offer in accordance with its terms and accept for payment and pay for all Shares tendered and not withdrawn promptly following the acceptance of Shares for payment pursuant to the Offer. The Offer shall be made by means of an offer to purchase (the "OFFER TO PURCHASE") that contains the terms set forth in this Agreement, and the conditions set forth in Annex I hereto. Parent expressly reserves the right to waive any of such conditions, to increase the Offer Price and to make any other changes in the terms of the Offer; provided, however, that Purchaser shall not, and Parent shall cause Purchaser not to, decrease the Offer Price, change the form of consideration payable in the Offer, decrease the number of Shares sought in the Offer, impose additional conditions to the Offer, extend the offer beyond the date that is twenty (20) business days after commencement of the Offer or the last extension (in accordance with this Section 1.1, if any, of the Offer, whichever is later (the "EXPIRATION DATE") except as set forth below, waive or change the Minimum Tender Condition (as defined in Annex I) or amend any other condition of the Offer in any manner adverse to the Company or the holders of the Shares, in each case without the prior written consent of the Company (such consent to be authorized by the Company Board of Directors or a duly authorized committee thereof). Notwithstanding the foregoing, Purchaser may, without the consent of the Company, (i) extend the Offer beyond the initial expiration date if, at any scheduled (or extended) expiration of the Offer, any of the conditions to Purchaser's obligation to accept Shares for payment, shall not be satisfied or waived, (ii) extend the Offer for any period required by any rule, regulation or interpretation of the United States Securities and Exchange Commission ("SEC"), or the staff thereof, applicable to the Offer, or (iii) extend (or re-extend) the Offer for an aggregate period of not more than twenty (20) business days (taking into account all such extensions and re extensions), beyond the latest applicable date that would otherwise be permitted under clause (i) or (ii) of this sentence, if, as of such date, all of the conditions to Purchaser's obligations to accept for payment Shares are satisfied or waived, but there shall not have been validly tendered and not withdrawn pursuant to the Offer that number of Shares necessary to permit the Merger to be effected without a meeting of the Company's stockholders in accordance with the DGCL. In addition, Purchaser may provide a "subsequent offering period" in accordance with Rule 14d-l1 under the Exchange Act. 2 (b) On the date of commencement of the Offer, Parent and Purchaser shall file with the SEC, pursuant to Regulation M-A under the Exchange Act ("REGULATION M-A"), a Tender Offer Statement on Schedule TO with respect to the Offer (together with all amendments, supplements and exhibits thereto, the "SCHEDULE TO"). The Schedule TO shall include the summary term sheet required under Regulation M-A and, as exhibits, the Offer to Purchase and a form of letter of transmittal and summary advertisement (collectively, together with any amendments and supplements thereto, the "OFFER DOCUMENTS"). The Company hereby consents to the inclusion in the Offer Documents of the recommendation referred to in clause (iii) of Section 3.19 and the approval of the Board of Directors referred to in Section 3.19. Parent and Purchaser agree to take all steps necessary to cause the Offer Documents to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities laws. Parent and Purchaser, on the one hand, and the Company, on the other hand, agree to promptly correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect or as otherwise required by law. Parent and Purchaser further agree to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities laws. The Company and its counsel shall be given a reasonable opportunity to review the Schedule TO before it is filed with the SEC. In addition, Parent and Purchaser agree to provide the Company and its counsel with any comments, whether written or oral, that Parent, Purchaser or their counsel may receive from time to time from the SEC or its staff with respect to the Offer Documents promptly upon receipt of such comments, and any written or oral responses thereto. (c) Parent shall provide or cause to be provided to Purchaser upon expiration of the Offer or any subsequent extension thereof, as applicable, all funds necessary to accept for payment, and pay for, any shares of Company Common Stock that are validly tendered and not withdrawn pursuant to the Offer and that Purchaser is obligated to accept for payment pursuant to the Offer and permitted to accept for payment under applicable Law. 1.2 COMPANY ACTIONS.

The Company further agrees to take all steps necessary to cause the Schedule 14D-9 to be filed with the SEC and disseminated to holders of Shares, in each case as and to the extent required by applicable federal securities laws.

The Company agrees to take all steps necessary to cause the Schedule 14D-9 as so corrected to be filed with the SEC and disseminated to holders of the Shares, in each case as and to the extent required by applicable federal securities laws. Parent, Purchaser and their counsel shall be given the opportunity to review and comment on the Schedule 14D-9 and any 3 amendment thereto before filing with the SEC. In addition, the Company agrees to provide Parent, Purchaser and their counsel in writing with any comments, whether written or oral, that the Company or its counsel may receive from time to time from the SEC or its staff with respect to the Schedule 14D-9 promptly after receipt of such comments, and to consult with Parent, Purchaser and their counsel prior to responding to any such comments, either in written or oral form. (b) In connection with the Offer, the Company shall promptly furnish or cause to be furnished to Parent or Purchaser mailing labels, security position listings and all available listings and computer files containing the names and addresses of the record holders of the Shares as of a recent date, and shall promptly furnish Parent or Purchaser with such information and assistance (including, but not limited to, lists of holders of the Shares, updated periodically, and their addresses, mailing labels and lists of security positions) as Parent or Purchaser or its agent(s) may reasonably request.

("NASDAQ"), in the event that the Parent, Purchaser or any other subsidiary of Parent shall acquire at least seventy-five percent (75%), but less than ninety percent (90%) of the outstanding shares of each class of capital stock of the Company entitled to vote on the Merger pursuant to the Offer, the Company shall, at the request of Parent, issue and sell to Purchaser up to the number of shares of Company Common Stock that represent nineteen and nine-tenths percent (19.9%) of the outstanding shares of Common Stock of the Company entitled to vote on the Merger at the greater of a purchase price of $22.50 per share and any higher price paid for any Share in the Offer. ARTICLE II CONVERSION OF SECURITIES 2.1 CONVERSION OF CAPITAL STOCK. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders of any shares of Company Common Stock or any shares of common stock, par value $0.001 per share, of Purchaser ("PURCHASER COMMON STOCK"): 6 (a) Purchaser Common Stock. Each issued and outstanding share of Purchaser Common Stock shall be converted into and become one fully paid and nonassessable share of common stock of the Surviving Corporation. (b) Cancellation of Treasury Stock and Parent-Owned Stock. All Shares that are owned by the Company as treasury stock and any Shares owned by Parent or Purchaser shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor. (c) Conversion of Shares. Each issued and outstanding Share (other than Shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Shares (as defined in Section 2.3(a))) shall be converted into the right to receive the Offer Price, payable to the holder thereof in cash, without interest (the "MERGER CONSIDERATION"). From and after the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such Shares shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration therefor upon the surrender of such certificate in accordance with Section 2.2, without interest thereon. 2.2 EXCHANGE OF CERTIFICATES. (a) Paying Agent. Parent shall designate a bank or trust company to act as agent for the holders of Shares in connection with the Merger (the "PAYING AGENT") and to receive the funds to which holders of Shares shall become entitled pursuant to Section 2.1(c). Prior to the Effective Time, Parent shall deposit, or cause to be deposited (by Purchaser or otherwise), with the Paying Agent the aggregate Merger Consideration. For purposes of determining the amount of Merger Consideration to be so deposited, Parent and Purchaser shall assume that no stockholder of the Company will perfect any right to appraisal of his, her or its Shares. Such funds shall be invested by the Paying Agent as directed by Parent or the Surviving Corporation, in its sole discretion (provided that Parent shall be responsible for replacing any losses of principal to such fund resulting from such investments), pending payment thereof by the Paying Agent to the holders of the Shares. Earnings from such investments shall be the sole and exclusive property of Parent and the Surviving Corporation, and no part of such earnings shall accrue to the benefit of holders of Shares. (b) Exchange Procedures. Promptly after the Effective Time, the Paying Agent shall mail to each holder of record of a certificate or certificates, which immediately prior to the Effective Time represented outstanding Shares (the "CERTIFICATES"), whose shares were converted pursuant to Section 2.1(c) into the right to receive the Merger Consideration (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Paying Agent and shall be in such form and have such other provisions as Parent may reasonably specify); and (ii) instructions for effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. Upon surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed and properly completed, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration for each Share formerly represented by such 7 Certificate and the Certificate so surrendered shall forthwith be cancelled. Until surrendered as contemplated by this Section 2.2, each Certificate shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration in cash as contemplated by this Section 2.2, without interest thereon, and shall not evidence any interest in, or any right to exercise the rights of a stockholder or other equity holder of, the Company or the Surviving Corporation. Notwithstanding the foregoing, any surrendered Certificate that represents Dissenting Shares shall be returned to the person surrendering such certificate. (c) Transfer Books; No Further Ownership Rights in Shares. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of Shares on the records of the Company. From and after the Effective Time, the holders of Certificates evidencing ownership of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares, except as otherwise provided for herein or by applicable law. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Article II. (d) Termination of Fund; No Liability. At any time following six (6) months after the Effective Time, the Surviving Corporation shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) made available to the Paying Agent and not disbursed (or for which disbursement is pending subject only to the Paying Agent's routine administrative procedures) to holders of Certificates, and thereafter such holders shall be entitled to look only to the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates, without any interest thereon. Notwithstanding the foregoing, none of Parent, the Surviving Corporation nor the Paying Agent shall be liable to any holder of a Certificate for Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If Certificates are not surrendered prior to two (2) years after the Effective Time, unclaimed Merger Consideration payable with respect to such Shares shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto. (e) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such person of a bond in such amount as Parent may reasonably direct as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Paying Agent shall issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto. 2.3 DISSENTING SHARES.

From and after the Effective Time, a stockholder who has properly exercised such appraisal rights shall not have any rights of a stockholder of the Company or the Surviving Corporation with respect to such Shares, except those provided under Section 262 of the DGCL. A holder of Dissenting Shares shall be entitled to receive payment of the appraised value of such Shares held by him, her or it in accordance with Section 262 of the DGCL, unless, after the Effective Time, such holder fails to perfect or withdraws or loses his, her or its right to appraisal, in which case such Shares shall be converted into and represent only the right to receive the Merger Consideration, without interest thereon, upon surrender of the Certificate or Certificates representing such Shares, pursuant to Section 2.2. (b) The Company shall give Parent (i) prompt notice of any written demands for appraisal of any Shares, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to rights of appraisal; and (ii) the opportunity to participate in the conduct of all negotiations and proceedings with respect to demands for appraisal under the DGCL.

Effective as of the Effective Time, all repurchase rights in favor of the Company with respect to shares issued upon exercise of Company Options (including, but not limited to shares issued upon exercise of Fee Conversion Options) shall terminate automatically, and the unvested shares of Common Stock subject to those terminated rights shall immediately vest in full. As of the Effective Time, the Option Plans shall terminate and all rights under any provision of any other plan, program or arrangement providing for the issuance or grant of any other interest in respect of the capital stock of the Company or any Company Subsidiary shall be cancelled. The Company shall use all reasonable efforts to effectuate the foregoing, including, but not limited to, sending out the requisite notices and obtaining all consents necessary to cash out and cancel all Company Options necessary to ensure that, after the Effective Time, no person shall have any right under the Option Plans, except as set forth herein. 2.5 OTHER SECURITIES. (a) At the Effective Time, if the $10 million Convertible Promissory Note due March 29, 2004 by the Company in favor of Warburg Dillon Read LLC (the "COMPANY NOTE") shall not have been converted by the holder thereof, the Company Note 9 shall be assumed by Parent.

Promptly after the commencement of the Offer, Parent shall execute and deliver to the holder of the Company Note a supplemental agreement regarding the conversion of the Company Note following the Effective Time in accordance with Sections 1(h) and 4(a)(1) of the Company Note and the Company shall deliver to the holder of the Company Note the officer's certificate and legal opinion contemplated by Section 4(a)(3) of the Company Note.

If payment of the Offer Price payable to a holder of Shares pursuant to the Offer or the Merger is to be made to a person other than the person in whose name the surrendered Certificate is registered, it shall be a condition of payment that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the person requesting such payment shall have paid all transfer and other Taxes required by reason of the issuance to a person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of Parent that such Tax either has been paid or is not applicable. 10 ARTICLE III REPRESENTATIONS AND WARRANTIES OF THE COMPANY Except as disclosed in that section of the letter of even date herewith delivered by the Company to Parent prior to the execution and delivery of this Agreement (the "COMPANY DISCLOSURE LETTER") corresponding to the section of this Agreement to which any of the following representations or warranties pertain, the Company represents and warrants to Parent as set forth below.

(a) Each of the Company and its Representatives (as defined below) has ceased and caused to be terminated all existing solicitations, initiations, encouragements, discussions, negotiations and communications with any persons or entities with respect to any offer or proposal or potential offer or proposal relating to any transaction or proposed transaction or series of related transactions, other than the Transactions, involving: (A) any acquisition or purchase from the Company by any person or "group" (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a twenty percent (20%) interest in the total outstanding voting securities of the Company or any of its Subsidiaries or any tender offer or exchange offer that if consummated would result in any person or "group" (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) beneficially owning twenty percent (20%) or more of the total outstanding voting securities of the Company or any of its Subsidiaries or any merger, (B) any consolidation, business combination, merger or similar transaction involving the Company; (C) any sale, lease (other than in the ordinary course of business), exchange, transfer, license (other than in the ordinary course of business), acquisition or disposition of assets of the Company or its Subsidiaries (including for this purpose the outstanding equity securities of the Company's Subsidiaries) for consideration equal to twenty percent (20%) or more of the fair market value of all of the outstanding shares of Company Common Stock on the date prior to the date hereof; or (D) any recapitalization, restructuring, liquidation or dissolution of the Company (each of clauses (A)-(D), an "ACQUISITION PROPOSAL"). Except as provided in Section 5.2(b) or (c), from the date of this Agreement until the earlier of termination of this Agreement or the Effective Time, the Company shall not and shall not authorize or permit its officers, directors, employees, investment bankers, attorneys, accountants or other agents or those of its subsidiaries (collectively, "REPRESENTATIVES") to directly or indirectly (i) initiate, solicit or knowingly encourage, or knowingly take any action to facilitate the making of, any offer or proposal which constitutes or is reasonably likely to lead to any Acquisition Proposal, (ii) enter into any agreement with respect to any Acquisition Proposal, or (iii) engage in negotiations or discussions with, or provide any information or data to, any person (other than Parent or any of its affiliates or representatives) relating to any Acquisition Proposal or grant any waiver or release under any standstill or other agreement. Notwithstanding the foregoing, nothing contained in this Section 5.2 or any other provision hereof shall prohibit the Company or the Company Board of Directors from (x) taking and disclosing to the Company's stockholders its position with respect to any tender or exchange offer by a third party pursuant to Rules 14d-9 and 14e-2 promulgated under the Exchange Act, or (y) making such disclosure to the Company's stockholders as in the good faith judgment of the Company Board of Directors, after receipt of advice from outside legal counsel, is required under applicable law and that the failure to make such disclosure is reasonably likely to cause the Company Board of Directors to violate its fiduciary duties to the Company's stockholders under applicable law. (b) Notwithstanding the foregoing, prior to the acceptance of Shares pursuant to the Offer, the Company may furnish information concerning its business, properties or assets to 35 any person pursuant to a confidentiality agreement with terms no less favorable to the Company than those contained in the confidentiality agreement, dated June 12, 2003 entered into between Parent and the Company (as amended by Section 9.5(b) of this Agreement, the "CONFIDENTIALITY AGREEMENT"), and may negotiate and participate in discussions and negotiations with such person concerning an Acquisition Proposal if, but only if, (x) such Acquisition Proposal provides for consideration to be received by the holders of all, but not less than all, of the issued and outstanding Shares (a "TAKEOVER PROPOSAL"); (y) such person has, in the absence of any violation of this Section 5.2 by the Company, submitted a bona fide written proposal to the Company relating to any such Takeover Proposal which the Board of Directors determines in good faith involves consideration to the holders of the Shares that is superior to the consideration offered pursuant to the Offer, otherwise represents a superior transaction to the Offer and the Merger, is reasonably capable of being consummated by the Termination Date (as defined in Section 8.1(b)) and which is not conditioned upon obtaining additional financing, or any regulatory approvals beyond or in addition to those regulatory approvals specifically referenced in Section 7.1(d), and (z) in the good faith opinion of the Company Board of Directors, after receipt of advice from outside legal counsel, providing such information or access or engaging in such discussions or negotiations is in the best interests of the Company and its stockholders and the failure to provide such information or access or to engage in such discussions or negotiations is reasonably likely to cause the Company Board of Directors to violate its fiduciary duties to the Company's stockholders (a Takeover Proposal which satisfies clauses (x), (y) and (z) being referred to herein as a "SUPERIOR PROPOSAL"). The Company shall promptly (and in any case within 24 hours) notify Parent (i) of such Superior Proposal, which notice shall include a copy of such Superior Proposal and (ii) upon receipt of any inquiries, proposals or offers received by, any request for information from, or any discussions or negotiations sought to be initiated or continued with, either the Company, or of its Subsidiaries or Representatives concerning an Acquisition Proposal or that would reasonably be expected to lead to an Acquisition Proposal and disclose the identity of the other party and the material terms of such inquiry, offer, proposal or request and, in the case of written materials, provide copies of such materials. The Company will keep Parent informed on a reasonably prompt basis (and, in any case, within 24 hours of any significant development) of the status and details (including amendments and proposed amendments) of any such Superior Proposal or other inquiry, offer, proposal or request. The Company shall promptly, following a determination by the Company Board of Directors that a Takeover Proposal is a Superior Proposal, notify Parent of such determination. (c) Except as set forth herein, neither the Company Board of Directors nor any committee thereof shall (i) withdraw or modify, or propose to withdraw or modify, in a manner adverse to the Transactions contemplated by this Agreement to Parent or Purchaser, the approval or recommendation by the Company Board of Directors or any such committee of the Offer, this Agreement or the Merger, (ii) approve or recommend or propose to approve or recommend, any Acquisition Proposal or (iii) enter into any agreement with respect to any Acquisition Proposal. Notwithstanding the foregoing, prior to the time of acceptance for payment of Shares in the Offer, the Company Board of Directors may (subject to the terms of this and the following two sentences) withdraw or modify its approval or recommendation of the Offer, this Agreement or the Merger, or recommend a Superior Proposal, in either case at any time after (x), it has concluded in good faith, after receipt of advice from outside legal counsel, that the failure to take such action is reasonably likely to result in a breach of its fiduciary duties to the Company's stockholders and (y) the fifth (5th) business day following the Company's delivery to Parent of 36 written notice advising Parent that the Company Board of Directors has received a Superior Proposal (which notice shall include a copy of such Superior Proposal) and identify the Person making such Superior Proposal and advising Parent that the Company intends to withdraw or modify its recommendation of the Offer, this Agreement or the Merger or recommend a Superior Proposal (specifying which course of action the Company intends to take) (a "SUBSEQUENT DETERMINATION"). After providing such notice, the Company shall provide to Parent two (2) business days from the date of such notice to make such adjustments in the terms and conditions of this Agreement as would enable the Company to proceed with its original recommendation to stockholders without making a Subsequent Determination; provided, however, that any such adjustments shall be at the discretion of the parties at such time. Any such withdrawal, modification or change of the recommendation of the Company Board of Directors, or recommendation or proposed recommendation of any Superior Proposal shall not change the approval of the Company Board of Directors for purposes of causing any state takeover statute or other state law to be inapplicable to the Transactions contemplated by this Agreement, including each of the Offer and the Merger. ARTICLE VI ADDITIONAL AGREEMENTS 6.1 PROXY STATEMENT. If required by the Exchange Act, the Company shall prepare and file with the SEC, as promptly as practicable after the consummation of the Offer, and shall use its reasonable efforts to respond promptly to any comments made by the SEC, and promptly thereafter shall mail to stockholders, the Proxy Statement.

In connection with the Special Meeting, if any, the Company shall, subject to the terms and conditions of this Agreement, use its reasonable efforts to solicit from stockholders of the Company proxies in favor of the Merger, and shall take all other action necessary or, in the reasonable opinion of Purchaser, advisable to secure any vote or consent of such stockholders required by the DGCL and the Company's Certificate of Incorporation to effect the Merger. Purchaser agrees that it shall vote, or cause to be voted, in favor of the Merger all Shares directly or indirectly beneficially owned by it. 6.3 CONFIDENTIALITY; ACCESS TO INFORMATION.

Unless otherwise required by law or regulation or pursuant to the terms and provisions of the Confidentiality Agreement, Parent and the Purchaser will hold any information which is non-public in confidence in accordance with the terms of the Confidentiality Agreement and, in the event this Agreement is terminated for any reason, Parent or the Purchaser shall promptly return or destroy such information in accordance with the Confidentiality Agreement. (b) The Company will afford Parent and its Representatives reasonable access during normal business hours to the properties, books, analysis, projections, plans, systems, 37 contracts, commitments, records, personnel offices and other facilities of the Company and its subsidiaries during the period prior to the Effective Time to obtain information concerning the business, including the status of product development efforts, properties, results of operations and personnel of the Company and use commercially reasonable efforts to make available at reasonable times during normal business hours to Parent and its Representatives, the appropriate individuals (including management personnel, attorneys, accountants and other professionals) for discussion of the Company's business, properties, prospects and personnel as Parent may reasonably request. 6.4 PUBLIC DISCLOSURE. The initial press release concerning the Offer and the Merger shall be a joint press release and, thereafter, so long as this Agreement is in effect, neither Parent, Purchaser nor the Company will disseminate any press release or other announcement concerning the Merger, the Offer or this Agreement or the other Transactions contemplated by this Agreement to any third party, except as may be required by law or by any listing agreement with the Nasdaq National Market, without the prior consent of each of the other parties hereto, which consent shall not be unreasonably withheld. The parties have agreed to the text of the joint press release announcing the execution of this Agreement. Notwithstanding the foregoing, without prior consent of the other party, each party (a) may communicate information that is not confidential to the other party with financial analysts, investors and media representatives in a manner consistent with its past practice in compliance with applicable Law and (b) may disseminate material substantially similar to material included in a press release or other document previously approved for external distribution by the other party. Each party agrees to promptly make available to the other party copies of any written communications made without prior consultation with the other party. 6.5 REGULATORY FILINGS; REASONABLE EFFORTS. (a) As promptly as practicable after the date hereof, each of Parent, Purchaser and the Company shall make all filings, notices, petitions, statements, registrations, submissions of information, application or submission of other documents required by any Governmental Entity in connection with the Merger and the other Transactions, including, without limitation: (i) Notification and Report Forms with the United States Federal Trade Commission (the "FTC") and the Antitrust Division of the United States Department of Justice ("DOJ") as required by the HSR Act, (ii) filings required by the merger notification or control laws of any applicable jurisdiction, as agreed by the parties hereto, and (iv) any filings required under the Securities Act, the Exchange Act, any applicable state or securities or "blue sky" laws and the securities laws of any foreign country, or any other applicable laws or rules and regulations of any Governmental Entity relating to the Merger. Each of Parent and the Company will cause all documents that it is responsible for filing with any Governmental Entity under this Section 6.5(a) to comply in all material respects with all applicable laws and rules and regulations of any Governmental Entity. (b) Each of Parent, Purchaser, and the Company shall promptly supply the other with any information which may be required in order to effectuate any filings or application pursuant to Section 6.5(a). Except where prohibited by applicable laws and rules and regulations of any Governmental Entity, and subject to the Confidentiality Agreement, each of the Company and Parent shall consult with the other prior to taking a position with respect to any such filing, 38 shall permit the other to review and discuss in advance, and consider in good faith the views of the other in connection with any analyses, appearances, presentations, memoranda, briefs, white papers, arguments, opinions and proposals before making or submitting any of the foregoing to any Governmental Entity by or on behalf of any party hereto in connection with any investigations or proceedings in connection with this Agreement or the transactions contemplated hereby (including under any antitrust or fair trade laws), coordinate with the other in preparing and exchanging such information and promptly provide the other (or its counsel) with copies of all filings, presentations or submissions (and a summary of any oral presentations) made by such party with any Governmental Entity in connection with this Agreement or the transactions contemplated hereby, provided that with respect to any such filing, presentation or submission, each of Parent and the Company need not supply the other (or its counsel) with copies (or in case of oral presentations, a summary) to the extent that any law, treaty, rule or regulation of any Governmental Entity applicable to such party requires such party or its Subsidiaries to restrict or prohibit access to any such properties or information. (c) Each of Parent, Purchaser and the Company will notify the others promptly upon the receipt of: (i) any comments from any officials of any Governmental Entity in connection with any filings made pursuant hereto and (ii) any request by any officials of any Governmental Entity for amendments or supplements to any filings made pursuant to, or information provided to comply in all material respects with, any applicable laws and rules and regulations of any Governmental Entity. Whenever any event occurs that is required to be set forth in an amendment or supplement to any filing made pursuant to Section 6.5(a), Parent, Purchaser or the Company, as the case may be, will promptly inform the others of such occurrence and cooperate in filing with the applicable Governmental Entity such amendment or supplement. (d) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use its reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other Transactions, including complying in all material respects with all applicable laws and with all rules and regulations of any Governmental Entity and using its reasonable efforts to accomplish the following: (i) the taking of its reasonable acts necessary to cause all the conditions set forth in Article VII and in Annex I hereto to be satisfied and to consummate and make effective the Merger and the other Transactions, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, clearances, approvals, orders and authorizations from Governmental Entities and the making of all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity, (iii) the obtaining of all necessary consents, approvals or waivers from third parties, (iv) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the Transactions, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (v) the execution or delivery of any additional instruments necessary to consummate the Transactions, and to carry out fully the purposes of, this Agreement. In connection with and without limiting the foregoing, the Company and its Board of Directors 39 shall, if any state takeover statute or similar statute or regulation is or becomes applicable to the Merger, this Agreement or any of the other Transactions, use all reasonable efforts to ensure that the Merger and the other Transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such statute or regulation on the Merger, this Agreement and the other Transactions. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of the Company, Parent and Purchaser shall use all reasonable efforts to take, or cause to be taken, all such necessary actions. Parent shall cause Purchaser to fulfill all Purchaser's obligations under, and pursuant to, this Agreement. Nothing in this Agreement shall require Parent, Purchaser or any other subsidiary of Parent to sell, hold separate, license or otherwise dispose of or conduct their business in a specified manner, or agree to sell, hold separate, license or otherwise dispose of or conduct their business in a specified manner, or permit the sale, holding separate, licensing or other disposition of, any assets of Parent, Purchaser or any other subsidiary of Parent, whether as a condition to obtaining any approval from a Governmental Entity or any other person or for any other reason. Until this Agreement is terminated in accordance with Section 8.1, Parent shall have the right to participate in the defense of any action, suit or proceeding instituted against the Company (or any of its directors or officers) before any court or governmental or regulatory body or threatened by any governmental or regulatory body, to restrain, modify or prevent the consummation of the Transactions, or to seek damages or a discovery order in connection with such Transactions. 6.6 NOTIFICATION OF CERTAIN MATTERS. Each party shall give prompt notice to the other parties of (i) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which would cause any representation or warranty made by such party in this Agreement to be untrue or inaccurate in any material respect at any time from the date hereof to the Effective Time, (ii) any condition set forth in Annex I that is unsatisfied in any material respect at any time from the date hereof to the date the Purchaser purchases Shares pursuant to the Offer (except to the extent it refers to a specific date), and (iii) any material failure of such party or any of its representatives to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties, the conditions to the obligations of the parties under this Agreement or the remedies available to the party receiving such notification. 6.7 INDEMNIFICATION. (a) Parent agrees that at all times after the Effective Time, it shall indemnify, or shall cause the Surviving Corporation and its subsidiaries to indemnify, each person who is now, or has been at any time prior to the date hereof, a director or officer of the Company or of any of the Company's subsidiaries, successors and assigns (individually an "INDEMNIFIED PARTY" and collectively the "Indemnified Parties"), to the same extent and in the same manner as is now provided in the respective Certificates of Incorporation or Bylaws of the Company and such subsidiaries and any Indemnity Agreement currently in effect, with respect to any claim, liability, loss, damage, cost or expense (whenever asserted or claimed) ("INDEMNIFIED LIABILITY") based in whole or in part on, or arising in whole or in part out of, any matter existing or occurring at or prior to the Effective Time. Parent understands and agrees that, prior to the Effective Time, the Company intends to obtain a six year "tail" insurance policy that provides coverage substantially 40 similar to the coverage provided under the Company's directors and officers insurance policy in effect on the date of this Agreement for the individuals who are directors and officers of the Company on the date of this Agreement for events occurring prior to the Effective Time; provided, however, without Parent's prior written consent (which consent shall not be unreasonably withheld or delayed), the Company shall not pay more than $3,500,000 to purchase such policy; provided, however, that prior to purchasing such policy, the Company shall afford Parent the opportunity to purchase a substitute policy on terms not materially less favorable to the Company and the Indemnified Parties. (b) This Section 6.7 is intended to be for the benefit of, and shall be enforceable by, the Indemnified Parties and their heirs and personal representatives and shall be binding on Parent and Surviving Corporation and its successors and assigns. In the event the Company or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each case, proper provision shall be made so that the successors and assigns of the Surviving Corporation honor the indemnification obligations set forth in this Section 6.7. (c) The Company Board of Directors shall take all action necessary to prevent Section 11(a) of any Indemnity Agreement from becoming applicable to the Agreement or the Transactions and to determine that the creation of any trust pursuant to Section 11(b) of any Indemnity Agreement would not be in the best interests of the Company. 6.8 EMPLOYEE BENEFITS. (a) Following the Merger, Parent shall cause the Surviving Corporation to provide that the employees of the Surviving Corporation are covered under Parent's then-current benefits plans, programs, policies and arrangements applicable to similarly situated employees of Parent.

If and only if requested by Parent, the Company shall terminate its 401(k) plan and its Nonqualifed Deferred Compensation Plan at least one day before the Closing Date. 6.9 CONSENTS AND APPROVALS.

Subject to the terms and conditions herein provided, each of the parties hereto agrees to use all reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable, whether under applicable laws and regulations or otherwise, or to remove any injunctions or other impediments or delays, legal or otherwise, to satisfy the conditions to the Offer and make effective the Merger and the other transactions contemplated by this Agreement. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of the Company and Parent shall use all reasonable efforts to take, or cause to be taken, all such necessary actions. 6.11 DIRECTORS. (a) Promptly upon the first acceptance for payment of, and payment by Purchaser for, any Shares which represent at least a majority of Fully Diluted Shares pursuant to the Offer, Parent shall be entitled to designate such number of directors on the Company Board of Directors as will give Parent, subject to compliance with Section 14(f) of the Exchange Act, representation on the Company Board of Directors equal to at least that number of directors, rounded up to the next whole number, which is the product of (x) the total number of directors on the Company Board of Directors (giving effect to the directors elected pursuant to this sentence) multiplied by (y) the percentage that (I) such number of Shares so accepted for payment and paid for by Purchaser plus the number of Shares otherwise owned by Parent, Purchaser or any other subsidiary of Parent bears to (II) the number of such Shares outstanding, and the Company shall, at such time, cause Parent's designees to be so elected; provided, however, that in the event that Parent's designees are appointed or elected to the Company Board of Directors, until the Effective Time the Company Board of Directors shall have at least three directors who are directors on the date of this Agreement and who are not officers of the Company (the "INDEPENDENT DIRECTORS"); and provided further that, in such event, if the number of Independent Directors shall be reduced below three for any reason whatsoever, any remaining Independent Directors (or Independent Director, if there shall be only one remaining) shall be entitled to designate persons to fill such vacancies who shall be deemed to be Independent Directors for purposes of this Agreement or, if no Independent Directors then remain, the other directors shall designate three persons to fill such vacancies who are not officers or affiliates of the Company, Parent or Purchaser, and such persons shall be deemed to be Independent Directors for purposes of this Agreement. At such time, the Company shall, upon Parent's request, also cause persons elected or designated by Parent to constitute the same percentage (rounded up to the next whole number) as is on the Company Board of Directors of (i) each committee of the Company Board of Directors of Directors, (ii) each board of directors (or 42 similar body) of each of the Company's Subsidiaries, and (iii) each committee (or similar body) of each such board, in each case only to the extent permitted by applicable law or the rules of any stock exchange on which the Company Common Stock is listed. Subject to applicable Law, the Company shall take all action requested by Parent necessary to effect any such election, including mailing to its stockholders the Information Statement containing the information required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder, and the Company shall make such mailing with the mailing of the Schedule 14D-9 (provided that Purchaser shall have provided to the Company on a timely basis all information required to be included in the Information Statement with respect to Purchaser's designees). In connection with the foregoing, the Company shall promptly, at the option of Purchaser, either increase the size of the Company Board of Directors or obtain the resignation of such number of its current directors, or both, as is necessary to enable Purchaser's designees to be elected or appointed to the Company Board of Directors as provided above. (b) Notwithstanding anything in this Agreement to the contrary, if Parent's designees constitute a majority of the Company Board of Directors after the acceptance for payment of Shares pursuant to the Offer and prior to the Effective Time, then the affirmative vote of a majority of the Independent Directors (or if only one exists, then the vote of such Independent Director) shall be required to (i) amend or terminate this Agreement by the Company, (ii) exercise or waive any of the Company's rights, benefits or remedies hereunder, if such action would materially and adversely affect holders of Shares other than Parent or Purchaser, (iii) amend the Certificate of Incorporation or Bylaws of the Company, or (iv) take any other action of the Company Board of Directors under or in connection with this Agreement or the Transaction; provided, however, that if there shall be no Independent Directors as a result of such persons' deaths, disabilities or refusal to serve, then such actions may be effected by majority vote of the entire Company Board of Directors.

or 45 (g) By either Parent or the Company, if upon a vote at a duly held meeting to obtain the Company Stockholder Approval, the Company Stockholder Approval is not obtained; provided, however, that Parent may not terminate this Agreement under this Section 8.1(g) if the Company Common Stock owned by Parent, Purchaser or any of Parent's Subsidiaries shall not have been voted in favor or obtaining the Company Stockholder Approval. 8.2 EFFECT OF TERMINATION (a) Any termination of this Agreement under Section 8.1 hereof will be effective immediately upon the delivery of a valid written notice of the terminating party to the other party hereto and, if then due, payment of the Termination Fee. In the event of termination of this Agreement as provided in Section 8.1 hereof, this Agreement shall forthwith become null and void and be of no further force or effect and there shall be no liability on the part of Parent, Purchaser or the Company (or any of their respective directors, officers, employees, stockholders, agents or representatives), except as set forth in Section 6.3(a), Article VIII and Article IX, each of which shall remain in full force and effect and survive any termination of this Agreement; provided, however, that nothing herein shall relieve any party from liability for fraud or the intentional and willful breach of any of its representations, warranties, covenants or agreements set forth in this Agreement. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement. (b) If Parent shall have terminated this Agreement pursuant to Section 8.1(e), the Company shall promptly pay Parent a termination fee (the "TERMINATION FEE") of $22,000,000. If the Company intends to terminate this Agreement pursuant to Section 8.1(f), it shall, prior to and as a condition to such termination, pay Parent the Termination Fee. If at any time when an Alternative Proposal has been publicly announced or otherwise communicated to the Company's Board of Directors and not withdrawn prior to the date of termination, Parent shall have terminated this Agreement pursuant to (I) Section 8.1(b)(ii) or Section 8.1(c)(i) or (II) Section 8.1(c)(ii) as a result of the failure to satisfy conditions (c) or (g) of Appendix A, and, in each case prior to the first anniversary of this Agreement, the Company enters into a written agreement, arrangement or understanding with respect to an Acquisition Proposal with any party other than Parent or its affiliates and consummates a transaction pursuant to such Acquisition Proposal, then the Company shall pay to Parent promptly, but in no event later than ten (10) business days after the consummation of such transaction, the Termination Fee. All amounts due hereunder shall be payable by wire transfer in immediately available funds to such account as Parent may designate in writing to the Company. In the event this Agreement is properly terminated in accordance with its terms by either the Company or Parent in a manner that requires the Company to pay Parent a Termination Fee, and Parent has received the Termination Fee, neither Parent nor Purchaser shall assert or pursue in any manner, directly or indirectly, (i) any claim or cause of action based in whole or in part upon alleged tortious or other interference with its rights under this Agreement against any entity or person submitting an Acquisition Proposal, (ii) any claim or cause of action against the Company, its affiliates or any of their respective officers, directors, employees, stockholders, agents or representatives based in whole or in part upon a breach of any representation, warranty or covenant in this Agreement, or (iii) any claim or cause of action against the Company, its affiliates or any of their respective officers, directors, employees, stockholders, agents or representatives based in whole or in part upon its or their receipt, 46 consideration, recommendation or approval of an Acquisition Proposal for the Company's exercise of its right of termination; provided, however, that the foregoing shall not relieve any party from liability for fraud or the intentional and willful breach of this Agreement. If the Company fails to promptly make any payment required under this Section 8.2(b) and Parent commences a suit to collect such payment, the Company shall indemnify Parent for its fees and expenses (including attorneys fees and expenses) incurred in connection with such suit and shall pay interest on the amount of the payment at the prime rate of Fleet National Bank (or its successors or assigns) in effect on the date the payment was payable pursuant to this Section 8.2(b). 8.3 FEES AND EXPENSES. Except as set forth in Section 8.2, all fees, costs and expenses incurred in connection with this Agreement and the Transactions shall be paid by the party incurring such expenses whether or not the Merger is consummated; provided, however, that Parent and the Company shall share equally all fees and expenses, other than attorneys' and accountants fees and expenses, incurred in relation to the printing and filing with the SEC and mailing of the Offer Documents, 14D-9 and Proxy Statement (including any preliminary materials related thereto) and any amendments or supplements thereto, and the filing of any documents required under the HSR Act or any comparable provisions under any applicable pre-merger notification laws or regulations of foreign jurisdictions. 8.4 EXTENSION; WAIVER. At any time prior to the Effective Time any party hereto may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto, and (iii) waive compliance with any of the agreements or conditions for the benefit of such party contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Delay in exercising any right under this Agreement shall not constitute a waiver of such right. ARTICLE IX GENERAL PROVISIONS 9.1 NON-SURVIVAL OF REPRESENTATIONS AND WARRANTIES. None of the representations and warranties in this Agreement or in any schedule, instrument or other document delivered pursuant to this Agreement shall survive the Effective Time and only the covenants that by their terms survive the Effective Time and this Article IX shall survive the Effective Time. 9.2 NOTICES.

The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision. 9.7 OTHER REMEDIES; SPECIFIC PERFORMANCE. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions 50 of this Agreement were not performed in accordance with their specific terms or were otherwise breached.

In the event that any action shall be brought in equity to enforce the provisions of the Agreement, neither party will allege, and each party hereby waives the defense, that there is an adequate remedy at law. 9.8 GOVERNING LAW; VENUE. This Agreement and all actions arising under or in connection therewith shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof, provided, however, that the laws of the respective jurisdictions of incorporation of each of the parties shall govern the relative rights, obligations, powers, duties and other internal affairs of such party and its board of directors.

This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. 9.12 NO WAIVER; REMEDIES CUMULATIVE. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. All rights and remedies existing under this Agreement are cumulative to, and not exclusive to, and not exclusive of, any rights or remedies otherwise available. 9.13 CONTROL OF COMPANY'S BUSINESS. Nothing contained in this Agreement shall give Parent, directly or indirectly, the right to control or direct the Company's operations prior to the consummation of the Offer. Prior to the consummation of the Offer, the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over its operations. 9.14 WAIVER OF JURY TRIAL.

The transaction is expected to be dilutive to Genzyme's GAAP earnings due to amortization through 2004. Excluding amortization, it is expected to be neutral to slightly accretive to Genzyme's earnings through 2004, and accretive beyond that time. With this transaction, Genzyme is acquiring a profitable and growing company with a leading antibody product used in organ transplantation, a well-respected U.S. and European field organization, and a strong development program with a significant pipeline in immune suppression and immunology. This pipeline is complementary to Genzyme's own work in immune-mediated diseases, such as scleroderma, multiple sclerosis, and pulmonary fibrosis. SangStat's lead product, Thymoglobulin(R) (anti-thymocyte globulin), is indicated in the United States for the treatment of acute rejection in patients with a renal transplant. The company reported revenues of $120 million in 2002, generating earnings of $0.24 per share. "This is a strong strategic fit for Genzyme, which adds a growing product, a strong pipeline, and a skilled team that nicely complements our ongoing programs in the high-potential area of immune mediated diseases," said Henri A. Termeer, chairman and chief executive officer, Genzyme Corporation. "Thymoglobulin is an excellent product that has the potential to transform the way transplant teams manage the care of their patients. We will use our combined resources and expertise to expand its areas of use and broaden its availability throughout the world." Thymoglobulin is an immunosuppressive polyclonal antibody product that suppresses certain types of immune cells responsible for acute organ rejection in transplant patients. Clinical studies have demonstrated that using Thymoglobulin to treat an acute rejection episode in a renal transplant patient may reverse the rejection episode. Acute rejection is the most common immunologic complication in transplant patients. In many European countries, Thymoglobulin is indicated for induction and treatment in solid organ transplants. In a number of these countries, it is indicated for the treatment of graft versus host disease, and for the treatment of aplastic anemia. In Japan and certain other countries, SangStat markets Lymphoglobuline(R) (anti-Thymocyte-globulin, equine) for the treatment of aplastic anemia and the prevention and treatment of graft rejection. Global sales of these products have grown steadily since Thymoglobulin was launched in the United States in 1999, reaching $77.4 million in 2002. Growth of Thymoglobulin has been buoyed in recent quarters by its increasing use in induction therapy at the time of kidney transplant. Genzyme intends to expand SangStat's clinical development programs in this area to fully develop this opportunity, and to pursue a broader indication for Thymoglobulin in the United States. Recently, SangStat received clearance for two investigational drug applications from the U.S. Food and Drug Administration to initiate new studies of Thymoglobulin in living donor kidney transplant patients and in bone marrow transplantation. Genzyme expects to drive Thymoglobulin growth primarily by gaining a broader clinical label, and by expanding sales in Europe and Latin America. "The synergies between Genzyme and SangStat are clear, and we believe this transaction brings significant value to SangStat's shareholders," said Richard D. Murdock, chairman, president, and chief executive officer, SangStat Medical Corporation. "In addition, SangStat is very pleased to add its successful team of dedicated professionals to one of the world's leading global biotechnology companies." SangStat also promotes Gengraf(TM) (cyclosporine), a branded generic cyclosporine co-marketed with Abbott Laboratories. Gengraf is a chronic immunosuppressant that is sold by the same sales force responsible for Thymoglobulin. This highly specialized sales force is focused primarily on the top 100 solid organ transplant centers, which account for approximately 75 percent of all kidney transplants. This focus on the kidney transplant area will complement Genzyme's own renal business, which is centered around Renagel(R) (sevelamer hydrochloride), a phosphate binder for patients with end stage renal disease on hemodialysis. Strategic Pipeline SangStat's lead pipeline candidate is RDP 58, an anti-inflammatory peptide that inhibits TNF-alpha, interferon-gamma, IL-12 and IL-2. The company is investigating RDP 58 for use across a range of immune-mediated diseases (IMDs), including ulcerative colitis (UC). SangStat recently reported positive Phase 2 results for UC and has announced that it is in partnership discussions regarding development of RDP 58 across a range of gastrointestinal diseases. Genzyme plans to continue these discussions, focusing on companies with the resources to develop and market this high potential product across the large medical community that treats these diseases. Genzyme has several complementary IMD products in development. CAT-192, a human anti-TGFfA monoclonal antibody, is being investigated in a Phase 2 trial with partner Cambridge Antibody Technology (CAT) for the treatment of diffuse systemic sclerosis. Genzyme is also conducting research examining the potential of this product in managing chronic organ rejection following transplantation. GENZ 29155, a small molecule for multiple sclerosis, is expected to enter clinical trials this year, and is being investigated as well for use in organ transplantation. GC 1008, a potential treatment for pulmonary fibrosis, is expected to enter clinical trials early next year in partnership with CAT. SangStat's RDP 58 has shown promising preclinical results in this indication. SangStat also has rights through a collaboration with Therapeutic Human Polyclonals, Inc. to an early stage research program focused on developing human polyclonal antibodies. If successful, this effort could enable far broader use of polyclonal antibodies in solid organ transplantation, autoimmune diseases, and the treatment of hematological tumors. This program, combined with Genzyme's own antigen discovery program, could accelerate the identification of targets and potential product candidates for development. Transaction Terms Genzyme's acquisition of SangStat will take the form of an all cash tender offer, which is expected to be completed in early September. The $22.50 per share transaction amount represents an approximately 45 percent premium over the closing price of SangStat's shares on Aug. 1. The transaction has been approved by the boards of directors of both companies, and is subject to clearance under the Hart-Scott-Rodino Antitrust Improvements Act. In association with the acquisition, Genzyme anticipates it will incur certain one time charges, which will be detailed at the close of the transaction.
