Each certificate evidencing any Restricted Securities and each certificate evidencing any such securities issued to subsequent transferees of any Restricted Securities shall (unless otherwise permitted by the provisions of Section 3.3 or 3.10 hereof) be stamped or otherwise imprinted with a legend in substantially the following form: THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAW. THE SECURITIES MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933 OR ANY APPLICABLE STATE SECURITIES LAW OR AN EXEMPTION THEREFROM UNDER SUCH ACT OR LAW. ADDITIONALLY, THE TRANSFER OF THESE SECURITIES IS SUBJECT TO THE - -------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 15 17 CONDITIONS SPECIFIED IN A STOCKHOLDERS' AGREEMENT DATED JUNE 1, 1997, AMONG THE CORPORATION AND CERTAIN OTHER SIGNATORIES THERETO, AND NO TRANSFER OF SUCH SECURITIES SHALL BE VALID OR EFFECTIVE UNTIL SUCH CONDITIONS HAVE BEEN FULFILLED. COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION. 3.3 Notice of Transfer. By acceptance of any Restricted Securities, the holder thereof agrees to give prior written notice to the Corporation of such holder's intention to effect any Transfer and to comply in all other respects with the provisions of this Section 3.3. Each such notice shall describe the manner and circumstances of the proposed Transfer and shall be accompanied by: (a) the written opinion of counsel for the holder of such Restricted Securities, or, at such holder's option, a representation letter of such holder, addressed to the Corporation (which opinion of counsel, or representation letter, as the case may be, shall be reasonably acceptable to the Corporation), as to whether, in the case of a written opinion, in the opinion of such counsel, such proposed Transfer involves a transaction requiring registration of such Restricted Securities under the Securities Act and applicable state securities laws or an exemption thereunder is available, or, in the case of a representation letter, such letter sets forth a factual basis for concluding that such proposed transfer involves a transaction requiring registration of such Restricted Securities under the Securities Act and applicable state securities laws or that an exemption thereunder is available; or (b) if such registration is required and if the provisions of Section 3.4 hereof are applicable, a written request addressed to the Corporation by the holder of such Restricted Shares pursuant to the terms and provisions of Section 3.4 hereof; provided, however, that in the case of any holder of Restricted Securities that is a partnership, no such opinion of counsel or representation letter of the holder shall be necessary for a Transfer by such holder to a partner of such holder, or a retired partner if, with respect to such Transfer by a partnership, (i) such Transfer is made in accordance with the partnership agreement of such partnership, and (ii) the transferee agrees in writing to be subject to the terms of Sections 3.1, 3.2, 3.3 and 3.10 hereof to the same extent as if such transferee were originally a signatory to this Agreement. If in such opinion of counsel or as reasonably concluded from the facts set forth in the representation letter of the holder (which opinion and counsel, or representation letter, as the case may be, shall be reasonably acceptable to the Corporation), the proposed Transfer may be effected without registration under the Securities Act and any applicable state securities laws or "blue sky" laws, then the holder of Restricted Securities shall thereupon be entitled to effect such Transfer in accordance with the terms of the notice delivered by it to the Corporation. 16 18 Each certificate or other instrument evidencing the securities issued upon such Transfer (and each certificate or other instrument evidencing any such securities not Transferred) shall bear the legend set forth in Section 3.2 hereof unless: (a) in such opinion of such counsel or as can be concluded from the representation letter of such holder (which opinion and counsel or representation letter shall be reasonably acceptable to the Corporation) the registration of future Transfers is not required by the applicable provisions of the Securities Act and state securities laws, or (b) the Corporation shall have waived the requirement of such legend; provided, however, that such legend shall not be required on any certificate or other instrument evidencing the securities issued upon such Transfer in the event such Transfer shall be made in compliance with the requirements of Rule 144 (as amended from time to time or any similar or successor rule) promulgated under the Securities Act. The holder of Restricted Securities shall not effect any Transfer until such opinion of counsel or representation letter of such holder has been given to and accepted by the Corporation (unless waived by the Corporation), which acceptance shall not be unreasonably withheld, or until registration of the Restricted Shares involved in the above-mentioned request has become effective under the Securities Act. In the event that an opinion of counsel is required by the registrar or transfer agent of the Corporation to effect a transfer of Restricted Securities in the future, the Corporation shall seek and obtain such opinion from its counsel, and the holder of such Restricted Securities shall provide such reasonable assistance as is requested by the Corporation (other than the furnishing of an opinion of counsel) to satisfy the requirements of the registrar or transfer agent to effectuate such transfer. 3.4 Required Registration. If the Corporation shall be requested (i) by holders of at least ** of the outstanding Restricted Securities (based on the underlying Common Stock for which the Restricted Securities are convertible or exercisable) to effect the registration under the Securities Act of Restricted Shares, or (ii) after the first registration pursuant to this Section 3.4, by one or more of the holders of Restricted Securities to effect the registration under the Securities Act of Restricted Shares having a proposed aggregate offering price equal to or greater than ** then the Corporation shall promptly give written notice of such proposed registration to all holders of Restricted Securities, and thereupon the Corporation shall promptly use its best efforts to effect the registration under the Securities Act of the Restricted Shares that the Corporation has been requested to register for disposition as described in the request of such holders of Restricted Securities and in any response received from any of the holders of Restricted Securities within 30 days after the giving of the written notice by the Corporation; provided, however, that the Corporation shall not be obligated to effect any registration under the Securities Act except in accordance with the following provisions and Section 3.6: - -------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 17 19 (a) Subject to Section 3.6, the Corporation shall not be obligated to file and cause to become effective more than two (2) registration statements requested by Roche, in which Restricted Shares are registered under the Securities Act pursuant to this Section 3.4, if all of the Restricted Shares offered pursuant to such registration statements are sold thereunder upon the price and terms offered. (b) Notwithstanding the foregoing, the Corporation may include in each such registration requested pursuant to this Section 3.4 any authorized but unissued shares of Common Stock (or authorized treasury shares) for sale by the Corporation or any issued and outstanding shares of Common Stock for sale by others; provided, however, that, if the number of shares of Common Stock so included pursuant to this clause (b) exceeds the number of Restricted Shares requested by the holders of Restricted Shares requesting such registration, then such registration shall be deemed to be a registration in accordance with and pursuant to Section 3.5; and provided further, however, that the inclusion of such previously authorized but unissued shares by the Corporation or issued and outstanding shares of Common Stock by others in such registration does not adversely affect, in the sole opinion of the holders of Restricted Securities requesting such registration, the ability of the holders of Restricted Securities requesting such registration to market the entire number of Restricted Shares requested by them. 3.5 Piggyback Registration. (a) Each time the Corporation proposes for any reason to register any of its securities under the Securities Act, other than pursuant to a registration statement on Form S-4 or Form S-8 or similar or successor forms (collectively, "Excluded Forms"), the Corporation shall promptly give written notice of such proposed registration to all holders of Restricted Securities, which shall offer such holders the right to request inclusion of any Restricted Shares in the proposed registration. (b) Each holder of Restricted Securities shall have 30 days from the receipt of such notice to deliver to the Corporation a written request specifying the number of Restricted Shares such holder intends to sell and the holder's intended method of disposition. (c) In the event that the proposed registration by the Corporation is, in whole or in part, an underwritten public offering of securities of the Corporation, any request under section 3.5(b) may specify that the Restricted Shares by included in the underwriting (i) on the same terms and conditions as the shares of Common Stock, if any, otherwise being sold through underwriters under such registration, or (ii) on terms and conditions comparable to those normally applicable to offerings of common stock in reasonably similar circumstances in the event that no shares of Common Stock other than Restricted Shares are being sold through underwriters under such registration. (d) Upon receipt of a written request pursuant to Section 3.5(b), the Corporation shall promptly use its best efforts to cause all such Restricted Shares to be registered under the Securities Act, to the extent required to permit sale or disposition as set forth in the written request. 18 20 (e) Notwithstanding the foregoing, if the managing underwriter of any such proposed registration determines and advises in writing that the inclusion of all Restricted Shares proposed by the holders thereof to be included in the underwritten public offering, together with any other issued and outstanding shares of Common Stock proposed to be included therein by holders other than the holders of Restricted Securities (such other shares hereinafter collectively referred to as the "Other Shares"), would materially interfere with the successful marketing of the Corporation's securities, then the total number of such securities proposed to be included in such underwritten public offering shall be reduced, (i) first by the shares requested to be included in such registration by the holders of Other Shares, and (ii) second, if necessary, (A) one-half (1/2) by the securities proposed to be issued by the Corporation, and (B) one-half (1/2) by the Restricted Shares proposed to be included in such registration by the holders thereof, on a pro rata basis, based upon the number of Restricted Shares sought to be registered by each such holder. The shares of Common Stock that are excluded from the underwritten public offering pursuant to the preceding sentence shall be withheld from the market by the holders thereof for a period, not to exceed 180 days from the closing of such underwritten public offering, that the managing underwriter reasonably determines as necessary in order to effect such underwritten public offering. 3.6 Registrations on Form S-2 and S-3. At such time as the Corporation shall have qualified for the use of Form S-2 or Form S-3 (or any successor form promulgated under the Securities Act), each holder of Restricted Securities shall have the right to request in writing an unlimited number (but not more than two (2) annually) of registrations on Form S-2 or Form S-3. Each such request by a holder shall: (a) specify the number of Restricted Shares which the holder intends to sell or dispose of, (b) state the intended method by which the holder intends to sell or dispose of such Restricted Shares, and (c) request registration of Restricted Shares having a proposed aggregate offering price of at least ** . Upon receipt of a request pursuant to this Section 3.6, the Corporation shall use its best efforts to effect such registration or registrations on Form S-2 or Form S-3. 3.7 Preparation and Filing. If and whenever the Corporation is under an obligation pursuant to the provision of this Section 3 to use its best efforts to effect the registration of any Restricted Shares, the Corporation shall, as expeditiously as practicable: (a) prepare and file with the Commission a registration statement with respect to such securities and use its best efforts to cause such registration statement to become and remain effective in accordance with Section 3.7(b) hereof; - -------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 19 21 (b) prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective until the earlier of (i) the sale of all Restricted Shares covered hereby or (ii) nine months, and to comply with the provisions of the Securities Act with respect to the sale or other disposition of all Restricted Shares covered by such registration statement; (c) furnish to each holder whose Restricted Shares are being registered pursuant to this Section 3 such number of copies of any summary prospectus or other prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such holder may reasonably request in order to facilitate the public sale or other disposition of such Restricted Shares; (d) use its best efforts to register or qualify the Restricted Shares covered by such registration statement under the securities or blue sky laws of such jurisdictions as each holder whose Restricted Shares are being registered pursuant to this Section 3 shall reasonably request and do any and all other acts or things which may be necessary or advisable to enable such holder to consummate the public sale or other disposition in such jurisdictions of such Restricted Shares; provided, however, that the Corporation shall not be required to consent to general service of process for all purpose in any jurisdiction where it is not then subject to process, qualify to do business as a foreign corporation where it would not be otherwise required to qualify or submit to liability for state or local taxes where it is not otherwise liable for such taxes; (e) at any time when a prospectus covered by such registration statement and relating thereto is required to be delivered under the Securities Act within the appropriate period mentioned in Section 3.7(b) hereof, notify each holder whose Restricted Shares are being registered pursuant to this Section 3 of the happening of any event as a result of which the prospectus included in such registration, 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 and, at the request of such holder, prepare, file and furnish to such holder a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit 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; (f) if the Corporation has delivered preliminary or final prospectuses to the holders of Restricted Shares that are being registered pursuant to this Section 3 and after having done so the prospectus is amended to comply with the requirements of the Securities Act, the Corporation shall promptly notify such holders and, if requested, such holders shall immediately cease making offers of Restricted Shares and return all prospectuses to the Corporation. The Corporation shall promptly provide such holders with revised prospectuses and, following receipt of the revised prospectuses, such holders shall be free to resume making offers of the Restricted Shares; and 20 22 (g) furnish, at the request of any holder whose Restricted Shares are being registered pursuant to this Section 3, on the date that such Restricted Shares are delivered to the underwriters for sale in connection with a registration pursuant to this Section 3, if such securities are being sold through underwriters, or, on the date that the registration statement with respect to such securities becomes effective, if such securities are not being sold through underwriters, (i) an opinion, dated such date, of the counsel representing the Corporation for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the holder or holders making such request, and (ii) a letter dated such date, from the independent certified public accountants of the Corporation, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering , addressed to the underwriters, if any, and to the holder or holders making such request. 3.8 Expenses. The Corporation shall pay all expenses incurred by the Corporation in complying with the Section 3, including, without limitation, all registration and filing fees (including all expenses incident to filing with the National Association of Securities Dealers, Inc.), fees and expenses of complying with the securities and blue sky laws of all such jurisdictions in which the Restricted Shares are proposed to be offered and sold, printing expenses and fees and disbursements of counsel (including with respect to each registration effected pursuant to Sections 3.4, 3.5 and 3.6, the reasonable fees and disbursements of counsel for the holders of Restricted Shares that are being registered pursuant to this Section 3); provided, however, that all underwriting discounts and selling commissions applicable to the Restricted Shares covered by registrations effected pursuant to Section 3.4, 3.5 or 3.6 hereof shall be borne by the seller or sellers thereof, in proportion to the number of Restricted Shares sold by each such seller or sellers. 3.9 Indemnification. (a) Indemnity by the Corporation. In the event of any registration under the Securities Act of any Restricted Shares pursuant to this Section 3 or otherwise, or registration or qualification of any Restricted Shares pursuant to Section 3.7(d) hereof, the Corporation shall: (i) indemnify and hold harmless any seller of such shares (the "Seller"), any underwriter, any officer, director, employee or agent of any Seller or underwriter, and each other person or entity, if any, who controls any Seller or underwriter within the meaning of Section 15 of the Securities Act, against any losses, claims, damages or liabilities, joint or several ("Claims"), to which each such indemnified party may become subject, under the Securities Act or otherwise, insofar as any Claims (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the registration statement or preliminary prospectus (if used prior to the effective date of the registration statement) or summary or final prospectus or any amendment or supplement thereto (if used during the period the Corporation is required to keep the registration statement current) or any document filed under a state securities or blue sky law (collectively, "Registration Documents") or insofar as any Claims (or actions in respect thereof) arise out of or are based upon the omission or alleged omission to state in any Registration Document a material fact required to be 21 23 stated therein or necessary to make the statements made therein not misleading or insofar as any Claims (or actions in respect thereof) arise out of or are based upon any violation by the Corporation of any Federal, state or common law rule or regulation applicable to the Corporation; and (ii) reimburse each indemnified party for all legal or other expenses reasonably incurred by it in connection with investigating or defending any Claim or action, including any amounts paid in settlement of any litigation, commenced or threatened, if such settlement is effected with the written consent of the Corporation (which consent shall not unreasonably be withheld); provided, however, that the Corporation shall not be liable to a particular indemnified party to the extent that any Claim or expense arises out of or is based upon any untrue statement or omission made in any Registration Document in reliance upon and in conformity with written information furnished to the Corporation by or on behalf of such indemnified party through an instrument duly executed by such indemnified party specifically stating that it is for use in the preparation of the Registration Document. (b) Indemnity by the Sellers. In the event of any registration under the Securities Act of any shares of Common Stock pursuant to this Agreement, each Seller severally shall: (i) indemnify and hold harmless the Corporation, each of its directors, each of its officers who have signed the registration statement, each other person, if any, who controls the Corporation within the meaning of Section 15 of the Securities Act, and each underwriter and each other person, if any, who controls such underwriter within the meaning of Section 15 of the Securities Act against any Claims to which each such indemnified party may become subject under the Securities Act or otherwise, insofar as such Claims (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Document, or arise out of or are based upon the omission or alleged omission to state in any Registration Document a material fact required to be stated therein or necessary to make the statements made therein not misleading; and (ii) reimburse each indemnified party for all legal or other expenses reasonably incurred by it in connection with investigating or defending any such Claim or action, including any amounts paid in settlement of any litigation, commenced or threatened, if such settlement is effected with the prior written consent of the Seller (which consent shall not unreasonably be withheld); provided, however, that such indemnification or reimbursement shall be payable only if, and to the extent that, any Claim or expense arises out of or is based upon an untrue statement or omission made in any Registration Document in reliance upon and in conformity with written information furnished to the Corporation through an instrument duly executed by the Seller specifically stating that it is for use in the preparation thereof; and provided further that the liability of such Seller shall be limited to an amount equal to the net proceeds to such Seller of shares of Common Stock sold by such Seller pursuant to such registration as contemplated herein. (c) Procedure for Indemnification. Promptly after receipt by an indemnified party, under Section 3.9(a) or 3.9(b), of notice of the commencement of any action, the indemnified party 22 24 shall notify the indemnifying party in writing of the commencement thereof, if a claim in respect thereof is to be made against an indemnifying party under any of these Sections; but the omission of such notice shall not relieve the indemnifying party from liability which it may have to the indemnified party under this Section 3.9, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than under this Section 3.9. In case any action is brought against the indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and to the extent that it chooses, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party that it so chooses, the indemnifying party shall not be liable for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof; provided however, that (i) if the indemnifying party fails to take reasonable steps necessary to defend diligently the claim within 20 days after receiving notice from the indemnified party that the indemnified party believes it has failed to do so, or (ii) if the indemnified party who is a defendant in any action or proceeding which is also brought against the indemnifying party reasonably shall have concluded that there may be legal defenses available to the indemnified party which are not available to the indemnifying party, or (iii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, the indemnified party shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all indemnified parties in each jurisdiction, except to the extent any indemnified party or parties reasonably shall have concluded that there may be legal defenses available to such party or parties which are not available to the other indemnified parties or to the extent representation of all indemnified parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct) and the indemnifying party shall be liable for any expenses therefor. (d) Non-Exclusive Indemnity. Any indemnity agreements contained herein shall be in addition to any other rights to indemnification or contribution which any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made or omitted by or on behalf of any indemnified party. (e) Contribution. If for any reason the foregoing indemnity is unavailable, or is insufficient to hold harmless an indemnified party, then the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities or expenses: (i) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and the indemnified party on the other (determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties' relative intent, knowledge, 23 25 access to information and opportunity to correct or prevent such untrue statement or omission); or (ii) if the allocation provided by clause (i) above is not permitted by applicable law or provides a lesser sum to the indemnified party than the amount hereinafter calculated, in such proportion as is appropriate to reflect not only the relative fault of the indemnifying party and the indemnified party, but also the relative benefits received by the indemnifying party on the one hand and the indemnified party on the other (taking into consideration the fact that the provision of the registration rights hereunder is a material inducement to the Investors to acquire shares of Common Stock), as well as any other relevant equitable considerations. No person or entity found guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person or entity who was not found guilty of such fraudulent misrepresentation. Notwithstanding anything to the contrary in this Section 3.9(e), no indemnifying party (other than the Corporation) shall be required, pursuant to this Section 3.9(e), to contribute any amount in excess of the net proceeds received by such indemnifying party from the sale of shares of Common Stock in the offering to which the losses, claims, damages, liabilities or expenses of the indemnified party relate. (f) Notwithstanding any of the foregoing, if, in connection with an underwritten public offering of any Restricted Shares, the Corporation, the holders of such Restricted Shares and the underwriters enter into an underwriting or purchase agreement relating to such offering which contains substantially similar provisions covering indemnification among the parties, then the indemnification provision of this Section 3.9 shall be deemed inoperative for purposes of such offering. 3.10 Removal of Legends, Etc. Notwithstanding the foregoing provisions of this Section 3, the restrictions imposed by this Section 3 upon the transferability of any Restricted Securities shall cease and terminate when (a) any such Restricted Securities are sold or otherwise disposed of in accordance with the intended method of disposition by the seller or sellers thereof set forth in a registration statement or such other method contemplated by Section 3.3 hereof that does not require that the securities transferred bear the legend set forth in Section 3.2 hereof, including a Transfer pursuant to Rule 144 or a successor rule thereof (as amended from time to time), or (b) the holder of Restricted Securities has met the requirements for transfer of such Restricted Securities pursuant to subparagraph (k) of Rule 144 or a successor rule thereof (as amended from time to time) promulgated by the Commission under the Securities Act. Whenever the restrictions imposed by this Section 3 have terminated, a holder of a certificate for Restricted Securities as to which such restrictions have terminated shall be entitled to receive from the Corporation, without expense and the Corporation shall use its reasonable best efforts to provide such holder with, a new certificate not bearing the restrictive legend set forth in Section 3.2 hereof and not containing any other reference to the restrictions imposed by this Section 3. SECTION 4. Securities Act Registration Statements. Except for securities of the Corporation registered on Forms S-2 or S-3, or successor approved forms, of the Securities and Exchange Commission, the Corporation shall not file any registration statement under the 24 26 Securities Act covering any securities unless it shall first have given each holder of Restricted Securities written notice thereof. The Corporation further covenants that each holder of Restricted Securities shall have the right, at any time when it may be deemed to be a controlling person of the Corporation, within the meaning of the Securities Act, to participate in the preparation of such registration statement and to request the insertion therein of material furnished to the Corporation in writing which in such holder's judgment should be included. In connection with any registration statement referred to in this Section 4, the Corporation shall indemnify, to the extent permitted by law, each holder of Restricted Securities, its officers, partners and directors and each person, if any, who controls any such holder within the meaning of the Securities Act in the same manner and to the same extent as the Corporation is required to indemnify a seller of Restricted Securities in Section 3.9 hereof. If, in connection with any such registration statement, any holder of Restricted Securities shall furnish written information to the Corporation expressly for use in the registration statement, then such holder shall indemnify the Corporation, each director of the Corporation, each officer of the Corporation who signs such registration statement and each person, if any, who controls the Corporation within the meaning of the Securities Act to the same extent as a seller of Restricted Securities is required to indemnify such persons in Section 3.9 hereof. SECTION 5. ELECTION OF DIRECTORS. 5.1 Voting for Directors. At each annual meeting of the stockholders of the Corporation and at each special meeting of the stockholders of the Corporation called for the purposes of electing directors of the Corporation, and at any time at which stockholders of the Corporation shall have the right to, or shall, vote for or consent to the election of directors, then, in each such event, each Investor shall vote all Preferred Shares and any other shares of voting stock of the Corporation then owned (or controlled as to voting rights) by it, whether by purchase, exercises of rights, warrants or options, stock dividends or otherwise: (a) to fix and maintain the number of directors on the Board of Directors of the Corporation at no more than ** ; (b) to elect to the Board ** designated by Roche (the ** ) for so long as Roche owns at least ** of the shares of Series A Preferred Stock originally issued to it by the Corporation (subject to adjustment for stock splits, stock dividends, stock combinations, recapitalizations and like occurrences) ** ; and - -------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 25 27 (c) to elect to the Board ** designated by OSI (the ** ) and ** designated by Cold Spring Harbor Laboratory (the ** ) for so long as OSI and Cold Spring Harbor Laboratory, respectively, owns at least ** of the shares of Series A Preferred Stock originally issued to it by the Corporation (subject to adjustment for stock splits, stock dividends, stock combinations, recapitalizations and like occurrences).

The Corporation shall use its best efforts to effectuate the purposes of this Section 5, including promoting the adoption of any necessary amendment of the By-Laws of the Corporation and the Certificate. 5.3 Notices. The Corporation shall provide the Investors with at least twenty (20) days' prior notice in writing of any intended mailing by the Corporation of notice to the Investors of a meeting at which directors are to be elected, and such notice shall include the names of the persons designated pursuant to Section 5.1 hereof. Roche, OSI and Cold Spring Harbor Laboratory, respectively, shall each notify the Corporation in writing at least three (3) days prior to such mailing, of the persons designated by Roche, OSI and Cold Spring Harbor Laboratory pursuant to Section A.5.1 hereof, as nominees for election to the Board. In the absence of any notice from Roche, OSI and Cold Spring Harbor Laboratory, as the case may be, the director(s) then serving and previously designated shall be renominated. 5.4 Removal. Except as otherwise provided in this Section 5, no Investor shall vote to remove any member of the Board designated in accordance with the foregoing provisions of this Section 5 unless the party that designated such director (the "Designating Party") shall so vote or otherwise consent, and, if the Designating Party shall so vote or otherwise consent, then the non-designating party shall likewise so vote. Except as otherwise provided in this Section 5, any vacancy on the Board created by the resignation, removal, incapacity or death of any person designated under the foregoing provisions of this Section 5 shall be filled by another person designated by the original Designating Party. Each Investor shall vote all shares of voting stock of the Corporation owned or controlled by such Investor in accordance with each such new designation, and no such vacancy shall be filled in the absence of a new designation by the original Designating Party. 5.5 Duration of Section. This Section 5 and the rights and obligations of the parties hereunder shall automatically terminate on the consummation of a firm commitment underwritten public offering of Common Stock registered under the Securities Act pursuant to which (X) Common Stock is offered to the public at a price of at least ** per share (subject to adjustment for stock splits, stock dividends, stock combinations, recapitalizations and like - -------------------- ** This portion has been redacted pursuant to a request for confidential treatment. 26 28 occurrences) and (Y) the net proceeds to the Corporation are at least ** (the "Termination Date"). Prior to the Termination Date the rights and obligations of any Investor under this Section 5 shall terminate upon the date on which such Investor no longer owns any Preferred Shares, whereupon the obligations of the remaining Investors to vote in favor of the designee, if any, of any such Investor shall also terminate. 5.6 Observation Rights.
