ARTICLE 12
INDEMNIFICATION

12.1 Indemnification by GSK. Subject to Sections 12.4 and 13.2, GSK shall defend, indemnify and hold harmless Theravance and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns from and against all Claims of Third Parties, and all associated Losses, to the extent arising out of (a) GSK's negligence or willful misconduct in performing any of its obligations under this Agreement, (b) a breach by GSK of any of its representations, warranties, covenants or agreements under this Agreement, or (c) the manufacture, use, handling, storage, marketing, sale, distribution or other disposition of Collaboration Products by GSK, its Affiliates, agents or sublicensees, except to the extent such losses result from the negligence or willful misconduct of Theravance.

12.2 Indemnification by Theravance. Subject to Sections 12.4 and 13.2, Theravance shall defend, indemnify and hold harmless GSK and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns from and against all Claims of Third Parties, and all associated Losses, to the extent arising out of (a) Theravance's negligence or willful misconduct in performing any of its obligations under this Agreement, or (b) a breach by Theravance of any of its representations, warranties, covenants or agreements under this Agreement.

12.3 Procedure for Indemnification.

12.3.1 Notice. Each Party will notify promptly the other in writing if it becomes aware of a Claim (actual or potential) by any Third Party (a "Third Party Claim") for which indemnification may be sought by that Party and will give such information with respect thereto as the other Party shall reasonably request. If any proceeding (including any governmental investigation) is instituted involving any Party for which such Party may seek an indemnity under Section 12.1 or 12.2, as the case may be (the "Indemnified Party"), the Indemnified Party shall not make any admission or statement concerning such Third Party Claim, but shall promptly notify the other Party (the "Indemnifying Party") orally and in writing and the Indemnifying Party and Indemnified Party shall meet to discuss how to respond to any Third Party Claims that are the subject matter of such proceeding. The Indemnifying Party shall not be obligated to indemnify the Indemnified Party to the extent any admission or statement made by the Indemnified Party or any failure by such Party to notify the Indemnifying Party of the claim materially prejudices the defense of such claim.

12.3.2 Defense of Claim. If the Indemnifying Party elects to defend or, if local procedural rules or laws do not permit the same, elects to control the defense of a Third Party Claim, it shall be entitled to do so provided it gives notice to the Indemnified Party of its intention to do so

within forty-five (45) days after the receipt of the written notice from the Indemnified Party of the potentially indemnifiable Third Party Claim (the "Litigation Condition"). The Indemnifying Party expressly agrees the Indemnifying Party shall be responsible for satisfying and discharging any award made to or settlement reached with the Third Party pursuant to the terms of this Agreement without prejudice to any provision in this Agreement or right at law which will allow the Indemnifying Party subsequently to recover any amount from the Indemnified Party to the extent the liability under such settlement or award was attributable to the Indemnified Party. Subject to compliance with the Litigation Condition, the Indemnifying Party shall retain counsel reasonably acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld, refused, conditioned or delayed) to represent the Indemnified Party and shall pay the reasonable fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party. The Indemnified Party shall not settle any claim for which it is seeking indemnification without the prior written consent of the Indemnifying Party which consent shall not be unreasonably withheld, refused, conditioned or delayed. The Indemnified Party shall, if requested by the Indemnifying Party, cooperate in all reasonable respects in the defense of such claim that is being managed and/or controlled by the Indemnifying Party. The Indemnifying Party shall not, without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any pending or threatened proceeding in which the Indemnified Party is, or based on the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on claims that are the subject matter of such proceeding. If the Litigation Condition is not met, then neither Party shall have the right to control the defense of such Third Party Claim and the Parties shall cooperate in and be consulted on the material aspects of such defense at each Party's own expense; provided that if the Indemnifying Party does not satisfy the Litigation Condition, the Indemnifying Party may at any subsequent time during the pendency of the relevant Third Party Claim irrevocably elect, if permitted by local procedural rules or laws, to defend and/or to control the defense of the relevant Third Party Claim so long as the Indemnifying Party also agrees to pay the reasonable fees and costs incurred by the Indemnified Party in relation to the defense of such Third Party Claim from the inception of the Third Party Claim until the date the Indemnifying Party assumes the defense or control thereof.

12.4 Assumption of Defense. Notwithstanding anything to the contrary contained herein, an Indemnified Party shall be entitled to assume the defense of any Third Party Claim with respect to the Indemnified Party, upon written notice to the Indemnifying Party pursuant to this Section 12.4, in which case the Indemnifying Party shall be relieved of liability under Section 12.1 or 12.2, as applicable, solely for such Third Party Claim and related Losses.

12.5 Insurance. During the Term of this Agreement and for a period of [*] after the termination or expiration of this Agreement, GSK shall obtain and/or maintain at its sole cost and expense, product liability insurance (including any self-insured arrangements) in amounts which are reasonable and customary in the U.S. pharmaceutical industry for companies of comparable size and activities. Such product liability insurance or self-insured arrangements shall insure against all liability, including without limitation personal injury, physical injury, or property damage arising out of the manufacture, sale, distribution, or marketing of the Collaboration Products. GSK shall provide written proof of the existence of such insurance to Theravance upon request.

ARTICLE 13
PATENTS

13.1 Prosecution and Maintenance of Patents.

13.1.1 Prosecution and Maintenance of Theravance Patents. Theravance shall have the exclusive right and the obligation to (subject to Theravance's election not to file, prosecute, or maintain pursuant to Section 13.1.4) or to cause its licensors to, prepare, file, prosecute in a diligent manner (including without limitation by conducting interferences, oppositions and reexaminations or other similar proceedings), maintain (by timely paying all maintenance fees, renewal fees, and other such fees and costs required under applicable Laws) and extend all Theravance Patents and related applications. Theravance shall consult with GSK prior to abandoning any Theravance Patents or related applications that are material to the matters contemplated in this Agreement. Theravance shall regularly advise GSK of the status of all pending applications, including with respect to any hearings or other proceedings before any Governmental Authority, and, at GSK's request, shall provide GSK with copies of all documentation concerning such applications, including all correspondence to and from any Governmental Authority. Subject to Section 2.3.3, Theravance shall solicit GSK's advice and review of the nature and text of such patent applications and important prosecution matters related thereto in reasonably sufficient time prior to filing thereof, and Theravance shall take into account GSK's reasonable comments related thereto; provided, however, Theravance shall have the final decision authority with respect to any action relating to any Theravance Patent. Within the priority period, Theravance shall agree with GSK regarding the countries outside the United States in which corresponding applications should be filed ("OUS Filings"). It is presumed that a corresponding Patent Cooperation Treaty ("PCT") application will be filed unless otherwise agreed by the Parties. Theravance shall effect filing of all such applications within the priority period.

Subject to Section 13.1.4, Theravance shall be responsible for all costs incurred in the United States in connection with procuring Theravance Patents, including applications preparation, filing fees, prosecution, maintenance and all costs associated with reexamination and interference proceedings in the United States Patent and Trademark Office and United States Courts. GSK shall be responsible for all out-of-pocket costs and expenses incurred by Theravance after the Effective Date that are associated with procuring corresponding OUS patents, including without limitation PCT and individual country filing fees, translations, maintenance, annuities, and protest proceedings. For all such OUS patent applications, Theravance will invoice GSK on a quarterly basis beginning April 1, 2003, setting forth all such expenses incurred. Reimbursement will be made to Theravance in United States Dollars within thirty (30) days of receipt of the invoice by GSK. GSK will within thirty (30) days following the Effective Date identify the GSK representative that should receive such invoices from Theravance. GSK's obligations hereunder are in addition to any obligations of GSK under Section 13.1.2(b)

13.1.2 Prosecution and Maintenance of Patents Covering Joint Inventions.

(a) For Patents covering Joint Inventions, the Parties shall agree, without prejudice to ownership, which Party shall have the right to prepare and file a priority patent application, and prosecute such application(s) and maintain any patents derived therefrom, with the Parties equally sharing the reasonable out-of-pocket costs for the preparation, filing, prosecution and maintenance of such priority patent application. The Parties will reasonably cooperate to obtain any export licenses that might be required for such activities. Should the agreed upon Party elect not to prepare and/or file any such priority patent application, it shall (i) provide the other Party with written notice as soon as reasonably possible after making such election but in any event no later than sixty (60) days before the other Party would be faced with a possible loss of rights, (ii) give the other Party the right, at the other Party's discretion and sole expense, to prepare and file the

priority application(s), and (iii) offer reasonable assistance in connection with such preparation and filing at no cost to the other Party except for reimbursement of reasonable out-of-pocket expenses incurred by the agreed upon Party in rendering such assistance. The other Party, at its discretion and cost, shall prosecute such application(s) and maintain sole ownership of any patents derived therefrom.

(b) Within nine (9) months after the filing date of a priority application directed to an Invention, the Party filing the priority application shall request that the other Party identify those non-priority, non-PCT ("foreign") Countries in which the other Party desires that the Party filing the priority application file corresponding patent applications. Within thirty (30) days after receipt by the other Party of such request from the Party filing the priority application, the other Party shall provide to the Party filing the priority application a written list of such foreign countries in which the other Party wishes to effect corresponding foreign patent applications filings. The Parties will then attempt to agree on the particular countries in which such applications will be filed, provided that in the event agreement is not reached, the application will be filed in the disputed as well as the non-disputed countries (all such filings referred to hereinafter as "Designated Foreign Filings"). Thereafter, within twelve (12) months after the filing date of the priority application, the Party filing the priority application shall effect all such Designated Foreign Filings. It is presumed unless otherwise agreed in writing by the Parties, that a corresponding PCT application will be filed designating all PCT member countries. As to each Designated Foreign Filing and PCT application, GSK shall bear the costs for the filing and prosecutions of such Designated Foreign Filing and PCT application (including entering national phase in all agreed countries). Should the Party filing the priority application not agree to file or cause to be filed a Designated Foreign Filing, the other Party will have the right to effect such Designated Foreign Filing in its name.

(c) Should the filing Party pursuant to Section 13.1.2(a) or 13.1.2(b) no longer wish to prosecute and/or maintain any patent application or patent resulting from such application, the filing Party shall (i) provide the non-filing Party with written notice of its wish no later than sixty (60) days before the patent or patent applications would otherwise become abandoned, (ii) give the non-filing Party the right, at the non-filing Party's election and sole expense, to prosecute and/or maintain such patent or patent application, and (iii) offer reasonable assistance to the non-filing Party in connection with such prosecution and/or maintenance at no cost to the non-filing Party except for reimbursement of the filing Party's reasonable out-of-pocket expenses incurred by the filing Party in rendering such assistance.

(d) Should the non-filing Party pursuant to Section 13.1.2(c) not wish to incur its share of preparation, filing, prosecution and/or maintenance costs for a patent application filed pursuant to Section 13.1.2(a) or 13.1.2(b) or patents derived therefrom, it shall (i) provide the filing Party with written notice of its wish, and (ii) continue to offer reasonable assistance to the filing Party in connection with such prosecution or maintenance at no cost to the filing Party except for reimbursement of the non-filing Party's reasonable out-of-pocket expenses incurred by the non-filing Party in rendering such assistance.

(e) The Parties agree to cooperate in the preparation and prosecution of all patent applications filed under Section 13.1.2(a) and 13.1.2(b), including obtaining and executing necessary powers of attorney and assignments by the named inventors, providing relevant technical reports to the filing Party concerning the invention disclosed in such patent application, obtaining execution of such other documents which shall be needed in the filing and prosecution of such patent applications, and, as requested, updating each other regarding the status of such patent applications.

13.1.3 Prosecution and Maintenance of GSK Patents. GSK shall have the exclusive right and obligation to (subject to GSK's election not to file, prosecute or maintain pursuant to Section 13.1.5) or to cause its licensors to, prepare, file and prosecute in a diligent manner (including without limitation by conducting interferences, oppositions and reexaminations or other similar proceedings), maintain (by timely paying all maintenance fees, renewal fees, and other such fees and costs required under applicable Laws) and extend all GSK Patents and related applications. Consistent with Section 2.3.3, GSK will consult with Theravance within the priority period for any patent application that is material to this Agreement concerning Countries in which corresponding applications will be filed. In the event the Parties can not agree, GSK shall make the final decision. GSK shall consult with Theravance prior to abandoning any GSK Patents or related applications that are material to the matters contemplated in this Agreement. GSK shall regularly advise Theravance of the status of all pending applications, including with respect to any hearings or other proceedings before any Governmental Authority, and, at Theravance's request, shall provide Theravance with copies of documentation relating to such applications, including all correspondence to and from any Governmental Authority. Subject to Section 2.3.3, GSK shall solicit Theravance's advice and review of the nature and text of such patent applications and important prosecution matters related thereto in reasonably sufficient time prior to filing thereof, and GSK shall take into account Theravance's reasonable comments relating thereto; provided that GSK shall have the final decision authority with respect to any action relating to a GSK Patent.

13.1.4 GSK Step-In Rights. If Theravance elects not to file, prosecute or maintain the Theravance Patents or claims encompassed by such Theravance Patents necessary for GSK to exercise its rights hereunder in any Country, Theravance shall give GSK notice thereof within a reasonable period prior to allowing such Theravance Patents, or such claims encompassed by such Theravance Patents, to lapse or become abandoned or unenforceable, and GSK shall thereafter have the right, at its sole expense, to prepare, file, prosecute and maintain such Theravance Patents in such Country.

13.1.5 Theravance Step-In Rights. If GSK elects not to file, prosecute or maintain the GSK Patents or claims encompassed by such GSK Patents necessary for Theravance to exercise its license rights hereunder in any Country, GSK shall give Theravance notice thereof within a reasonable period prior to allowing such GSK Patents, or such claims encompassed by such GSK Patents, to lapse or become abandoned or unenforceable, and Theravance shall thereafter have the right, at its sole expense, to prepare, file, prosecute and maintain such GSK Patents in such Country. In the event that GSK elects not to file, prosecute or maintain GSK Patents or claims that would affect the royalty owed Theravance pursuant to Section 6.3, GSK shall reimburse Theravance for all out-of-pocket expenses incurred by Theravance in connection with Theravance exercising its Step-In Rights under this Section.

13.1.6 Execution of Documents by Agents. Each of the Parties shall execute or have executed by its appropriate agents such documents as may be necessary to obtain, perfect or maintain any Patent Rights filed or to be filed pursuant to this Agreement, and shall cooperate with the other Party so far as reasonably necessary with respect to furnishing all information and data in its possession reasonably necessary to obtain or maintain such Patent Rights.

13.1.7 Patent Term Extensions. The Parties shall cooperate with each other in gaining patent term extension where applicable to Collaboration Products. The Joint Steering Committee shall determine which patents the Parties shall endeavor to have extended. All filings for such extension will be made by the Party to whom the patent is assigned after consultation with the other Party. In the event the Joint Steering Committee can not agree, the Party who is assigned the compound patent covering the LABA in the Collaboration Product will make the decision.

13.2 Patent Infringement.

13.2.1 Infringement Claims. With respect to any and all Claims instituted by Third Parties against Theravance or GSK or any of their respective Affiliates for patent infringement involving the manufacture, use, license, marketing or sale of a Collaboration Product in the United States during the Term (each, a "Patent Infringement Claim") as applicable, Theravance and GSK will assist one another and cooperate in the defense and settlement of such Patent Infringement Claims at the other Party's request.

13.2.2 Infringement of Theravance Patents. In the event that Theravance or GSK becomes aware of actual or threatened infringement of a Theravance Patent during the Term, that Party will promptly notify the other Party in writing (a "Patent Infringement Notice"). Theravance will have the right but not the obligation to bring an infringement action against any Third Party. If Theravance elects to pursue such infringement action, Theravance shall be solely responsible for the costs and expenses associated with such action and retain all recoveries. During the Term, in the event that Theravance does not undertake such an infringement action, upon Theravance's written consent, which shall not be unreasonably withheld, refused, conditioned or delayed, GSK shall be permitted to do so in Theravance's or the relevant Theravance Affiliate's name and on Theravance's or the relevant Theravance Affiliate's behalf. If Theravance has consented to an infringement action but GSK is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then GSK may join Theravance as party-plaintiff. If GSK elects to pursue such infringement action, Theravance may be represented in such action by attorneys of its own choice and its own expense with GSK taking the lead in such action.

13.2.3 Infringement of GSK Patents. In the event that GSK or Theravance becomes aware of actual or threatened infringement of a GSK Patent during the Term, that Party will promptly notify the other Party in writing. GSK will have the right but not the obligation to bring an infringement action against any Third Party. If GSK elects to pursue such infringement action, GSK shall be solely responsible for the costs and expenses associated with such action and retain all recoveries. During the Term, in the event that GSK does not undertake such an infringement action, upon GSK's written consent, which shall not be unreasonably withheld, refused, conditioned or delayed, Theravance shall be permitted to do so in GSK's or the relevant GSK Affiliate's name and on GSK's or the relevant GSK Affiliate's behalf. If GSK has consented to an infringement action but Theravance is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then Theravance may join GSK as a party-plaintiff. If Theravance elects to pursue such infringement action, GSK may be represented in such action by attorneys of its own choice and at its own expense, with Theravance taking the lead in such action.

13.3 Notice of Certification. GSK and Theravance each shall immediately give notice to the other of any certification filed under the "U.S. Drug Price Competition and Patent Term Restoration Act of 1984" (or its foreign equivalent) claiming that a GSK Patent or a Theravance Patent is invalid or that infringement will not arise from the manufacture, use or sale of any Collaboration Product by a Third Party ("Hatch-Waxman Certification").

13.3.1 Notice. If a Party decides not to bring infringement proceedings against the entity making such a certification, such Party shall give notice to the other Party of its decision not to bring suit within twenty-one (21) days after receipt of notice of such certification.

13.3.2 Option. Such other Party then may, but is not required to, bring suit against the entity that filed the certification.

13.3.3 Name of Party. Any suit by Theravance or GSK shall either be in the name of Theravance or in the name of GSK, (or any Affiliate) or jointly in the name of Theravance and GSK (or any Affiliate), as may be required by law.

13.4 Assistance. For purposes of this Article 13, the Party not bringing suit shall execute such legal papers necessary for the prosecution of such suit as may be reasonably requested by the Party bringing suit. The out-of-pocket costs and expenses of the Party bringing suit shall be reimbursed first out of any damages or other monetary awards recovered in favor of GSK or Theravance. The documented out-of-pocket costs and expenses of the other Party shall then be reimbursed out of any remaining damages or other monetary awards. The Party initiating and prosecuting the action to completion will retain any remaining damages or other monetary awards following such reimbursements.

13.5 Settlement. No settlement or consent judgment or other voluntary final disposition of a suit under this Article may be entered into without the joint written consent of GSK and Theravance (which consent will not be withheld unreasonably).

ARTICLE 14
TERM AND TERMINATION

14.1 Term and Expiration of Term. Unless otherwise mutually agreed to by the Parties, this Agreement shall commence on the Effective Date and shall end upon expiration of the Term, unless terminated early as contemplated hereunder.

The Breaching Party shall, if such breach can be cured, have sixty (60) days after written notice thereof was provided to the Breaching Party by the non-breaching Party to remedy such default (or, if such default cannot be cured within such 60-day period, the Breaching Party must commence and diligently continue actions to cure such default during such 60-day period). Any such termination shall become effective at the end of such 60-day period unless the Breaching Party has cured any such breach or default prior to the expiration of such 60-day period (or, if such default is capable of being cured but cannot be cured within such 60-day period, the Breaching Party has commenced and diligently continued actions to cure such default provided always that, in such instance, such cure must have occurred within one hundred twenty (120) days after written notice thereof was provided to the Breaching Party by the non-breaching Party to remedy such default).

14.3 GSK Right to Terminate Development of a Collaboration Product. On a Collaboration Product-by-Collaboration Product basis, and at any time during Development and prior to First Commercial Sale of the applicable Collaboration Product, GSK shall have the right to terminate Development of such Collaboration Product (upon the provision of ninety (90) days written notice) for reasons of Technical Failure or Commercial Failure following communication to, and assessment of such proposed termination by, the Joint Project Committee and Joint Steering Committee (in which case such Collaboration Product shall be referred to as a "Terminated Development Collaboration Product").

14.5 Termination of the Agreement Due to Discontinuation of Development of All Collaboration Products and All Pooled Compounds. Any time following the [*] the Effective Date, either Party may terminate this Agreement, subject to Section 14.10, upon the provision of ninety (90) days written notice if Development of all Collaboration Products and all Pooled Compounds have been discontinued for Technical Failure and/or Commercial Failure. Notwithstanding the foregoing, in the event that (i) Development of all Collaboration Products and all Pooled Compounds (including any Replacement Compounds) has ceased for at least [*], (ii) all such termination and/or discontinuance decisions have been validly approved by the Joint Steering Committee, and (iii) both parties have provided written notice to the other that such party does not intend to contribute any additional Replacement Compounds to the collaboration, then either Party shall be entitled to terminate this Agreement, subject to Section 14.10, upon the provision of ninety (90) days written notice.

This Agreement is made with the Investor in reliance upon the Investor's representation to the Company, which by the Investor's execution of this Agreement the Investor hereby confirms, that the Series E Preferred Stock to be received by the Investor and the Common Stock issuable upon conversion thereof (collectively, the "Securities") will be acquired for investment for the Investor's own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Investor has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of applicable securities laws. By executing this Agreement, the Investor further represents that the Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities.

3.3 Disclosure of Information. The Investor further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Series E Preferred Stock and the business, properties, prospects and financial condition of the Company. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section 2 of this Agreement or the right of the Investor to rely thereon.

3.4 Investment Experience. The Investor is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its

investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Series E Preferred Stock. The Investor also represents that it has not been organized for the purpose of acquiring the Series E Preferred Stock.

3.5 Accredited Investor. The Investor is an "accredited investor" within the meaning of SEC Rule 501 of Regulation D, as presently in effect.

3.6 Restricted Securities. The Investor understands that the Securities it is purchasing are characterized as "restricted securities" under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Act, only in certain limited circumstances. In this connection, the Investor represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Act.

3.7 Further Limitations on Disposition. Without in any way limiting the representations set forth above, the Investor further agrees not to make any disposition of all or any portion of the Securities unless and until the transferee has agreed in writing for the benefit of the Company to be bound by this Section 3 and the Investors' Rights Agreement provided and to the extent this Section and such agreements are then applicable, and:

(a) There is then in effect a Registration Statement under the Act covering such proposed disposition and such disposition is made in accordance with such Registration Statement; or

(b) (i) The Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, including, but not limited to, the name of the transferee, and (ii) if reasonably requested by the Company, the Investor shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company that such disposition will not require registration of such shares under the Act. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144 except in unusual circumstances.

(c) Notwithstanding the provisions of Section 3.2 or Paragraphs (a) and (b) above, no such registration statement or opinion of counsel shall be necessary for a transfer by the Investor (i) that is a partnership to a partner of such partnership or a retired partner of such partnership who retires after the date hereof, or to the estate of any such partner or retired partner or the transfer by gift, will or intestate succession of any partner to his or her spouse or to the siblings, lineal descendants or ancestors of such partner or his or her spouse, or (ii) to any entity that is not a natural person and is controlled by, controls or is under common control with the Investor, if the transferee agrees in writing to be subject to the terms hereof to the same extent as if he or she were an original Investor hereunder.

(d) In addition, Investor agrees that, without the Company's written consent, in no event shall any transfer of Securities by the Investor made prior to the initial public offering of the Company's Common Stock pursuant to an effective registration statement under the Act be effective if the transferee is a direct competitor with the primary business of the Company (as determined in the sole discretion of the Company's Board of Directors). The Company agrees that it shall not unreasonably withhold consent for any transfer by Investor to a member or affiliate of Investor or an affiliate of GlaxoSmithKline PLC.

3.8 Legends. It is understood that the certificates evidencing the Securities may bear one or all of the following legends:

(a) "These securities have not been registered under the Securities Act of 1933, as amended. They may not be sold, offered for sale, pledged or hypothecated in the absence of a registration statement in effect with respect to the securities under such Act or an opinion of counsel

satisfactory to the Company that such registration is not required or unless sold pursuant to Rule 144 of such Act."

(b) Any legend required by the laws of any state.

4. Conditions of Investor's Obligations at Closing.
