withheld) or as specifically set forth in the Research Plan, provided that (i) such Party shall obtain the written agreement of each such Third Party, prior to the time such Third Party initiates work, to assign ownership of Inventions made in the course of Research Program activities to such Party; (ii) each Party shall be responsible for the acts or omissions of any such Third Party which would constitute a breach of such Party’s obligations hereunder; (iii) any such Third Party shall comply with all relevant terms of this Agreement; and (iv) any such Third Party shall sign a confidentiality agreement with confidentiality and non-use obligations no less restrictive than those set forth in Article 4. Notwithstanding the above, in the event Genelabs desires to subcontract any research activities referred to in this paragraph, Genelabs shall first notify PHARMA thereof, and PHARMA shall have the right to perform such activities.

2.3 Expansion of Collaboration Field.

2.3.1 Right to Expand. At any time and from time to time during the Research Program Term, PHARMA shall have the right in its sole discretion, upon written notice to Genelabs, to expand the Collaboration Field to include Non-nucleoside inhibitors of the HCV NS5b RNA polymerase which are not then part of the Collaboration Field, except for any such inhibitors which are already subject to an exclusive Third Party Collaboration between Genelabs and a Third Party with respect to which Genelabs has provided PHARMA notice pursuant to and complied with the provisions of Section 2.3.2. For the avoidance of doubt, no additional upfront payments, funding of FTE’s or other compensation will be payable by PHARMA in consideration for the exercise of its right to expand the Collaboration Field pursuant to this Section 2.3.1.

2.3.2 Proposed Third Party Collaborations.

(a) If Genelabs or any Affiliate thereof, at any time and from time to time during the Research Program Term, desires to enter into a Third Party Collaboration with respect to the research, development and/or commercialization of any Non-nucleoside inhibitors of the HCV NS5b polymerase which are not then part of the Collaboration Field (a “Proposed Third Party Collaboration Field”), then each such time Genelabs shall promptly provide PHARMA with written notice thereof, which notice shall include all information and data in Genelabs’ possession or control relevant to the Proposed Third Party Collaboration Field or proposed Third Party Collaboration including all information proposed to be provided to Third Parties in contemplation of such Third Party Collaboration (the “Evaluation Information Package”).

(b) For a period of [**] from the date of receipt of such notice and information (the “Option Exercise Period”), PHARMA shall have the right to expand the Collaboration Field pursuant to Section 2.3.1 to include the Proposed Third Party Collaboration Field upon written notice to Genelabs within the Option Exercise Period. During the Option Exercise Period, PHARMA shall have the Evaluation Rights hereinafter defined in order to determine whether it wishes to expand the Collaboration Field.

(i) To receive the Evaluation Information Package as provided above;

(ii) To meet with and discuss the Proposed Third Party Collaboration Field with Genelabs’ and its Affiliates’ scientific personnel;

(iii) To receive samples from Genelabs and its Affiliates of any compound(s) within the Proposed Third Party Collaboration Field to conduct tests on such compounds; and

(iv) To conduct due diligence regarding the Proposed Third Party Collaboration Field.

The exercise of the Evaluation Rights shall be conducted pursuant to industry standard confidential disclosure agreements and material transfer agreements to be entered into by Genelabs and PHARMA and/or their respective Affiliates. Until expiration of the Option Exercise Period, neither Genelabs nor its Affiliates shall (i) provide any Evaluation Rights to any Third Party or otherwise solicit or encourage (including by way of furnishing information or samples), or undertake discussions or negotiations, or take any other action to facilitate or consummate, any inquiries or the making of any proposal, relating to a Third Party Collaboration with respect to the Proposed Third Party Collaboration Field or (ii) enter into a Third Party Collaboration with respect to the Proposed Third Party Collaboration Field. For the avoidance of doubt, the foregoing shall not prohibit disclosures relating to the Proposed Third Party Collaboration Field at scientific conferences or investor conferences, subject to the provisions of Section 4.4. This Section 2.3.2 also shall not prevent Genelabs from entering into agreements relating to the Proposed Third Party Collaboration Field with vendors solely for such vendors to provide products or services to Genelabs.

(d) In the event that PHARMA does not exercise its rights pursuant to Section 2.3.2(b) above with respect to the Proposed Third Party Collaboration Field within the Option Exercise Period, then Genelabs shall have the right, for a period of [**] following the expiration of the Option Exercise Period, to enter into a Third Party Collaboration with respect to the research, development and/or commercialization of compound(s) within the Proposed Third Party Collaboration Field. In the event that Genelabs does not enter into such a Third Party Collaboration within such [**] period, then, prior to Genelabs entering into a Third Party Collaboration with respect to such Proposed Third Party Collaboration Field or any portion thereof following the expiration of such [**] period, Genelabs shall be required to again comply with this Section 2.3.2 with respect to any proposed Third Party Collaboration relating to such Proposed Third Party Collaboration Field.

(iii) is subsequently disclosed to the receiving Party or its Affiliates on a non-confidential basis by a Third Party who may lawfully do so; or

(iv) is independently discovered or developed by the receiving Party or its Affiliates without the use of Confidential Information provided by the disclosing Party or its Affiliates, as documented by receiving Party’s or its Affiliates’ business records.

(b) Within thirty (30) days after any expiration or termination of this Agreement, each Party shall destroy (and certify to the other Party such destruction) or return all Confidential Information provided by the other Party or its Affiliates except as otherwise set forth in this Agreement, and except that each Party may retain a single copy of the Confidential Information in its confidential legal files for the sole purpose of ascertaining its ongoing rights and responsibilities regarding the Confidential Information.

4.2 Permitted Disclosures. Each Party and its Affiliates may disclose Confidential Information provided by the other Party or its Affiliates to the extent such disclosure is reasonably necessary in the following instances:

(a) disclosure to governmental or other regulatory agencies in order to obtain patents on Collaboration Technology, Joint Technology, PHARMA Background Technology and/or Genelabs Background Technology or to gain or maintain approval to conduct clinical trials or to market Product (in each case to the extent permitted by this Agreement), but such disclosure may be only to the extent reasonably necessary to obtain patents or authorizations;

(b) complying with applicable court orders or governmental regulations;

(c) disclosure by PHARMA to its Affiliates for the sole purpose of conducting development and/or commercialization of Collaboration Compounds and Products in accordance with the terms and conditions of this Agreement on the condition that such Affiliates agree to be bound by confidentiality and non-use obligations at least equivalent in scope to those contained in this Agreement; or

(d) disclosure to consultants, agents or other Third Parties solely to the extent required to accomplish the purposes of this Agreement or in connection with due diligence or similar investigations by such Third Parties, and disclosure to potential Third Party investors in confidential financing documents, in each case on the condition that such Third Parties agree to be bound by confidentiality and non-use obligations at least equivalent in scope to those contained in this Agreement or for the purposes of such financing.

Each Party shall obtain written agreements from each of its employees and consultants who perform work on the Research Program, to the extent that the equivalent of such agreements are not already in place, which agreements shall obligate such Persons to similar obligations of confidentiality and to assign to such Party all inventions made by such Persons during the course of performing the Research Program.

If a Party or its Affiliate is required by judicial or administrative process to disclose Information that is subject to the non-disclosure provisions of Section 4.1, such Party shall promptly inform the other Party of the disclosure that is being sought in order to provide the other Party an opportunity to challenge or limit the disclosure obligations. Information that is disclosed by judicial or administrative process shall remain otherwise subject to the confidentiality and non-use provisions of this Article 4, and the Party or Affiliate disclosing Information pursuant to law or court order shall take all reasonable steps necessary, including

without limitation obtaining an order of confidentiality, to ensure the continued confidential treatment of such Information.

4.3 Publications. The Parties acknowledge that scientific lead time is a key element of the value of the Research Program and further agree that scientific publications must be strictly monitored to prevent any adverse effect of the premature publication of results of the Research Program. The Parties shall establish a procedure for publication review and approval with respect to publications regarding the Research Program and each Party shall first submit to the other Party an early draft of all such publications, whether they are to be presented orally or in written form, at least sixty (60) days prior to submission for publication, submissions of an abstract on the presentation, as the case may be. Each Party shall review each such proposed publication in order to avoid the unauthorized disclosure of a Party’s Confidential Information and to preserve the patentability of inventions arising from the collaboration. If, as soon as reasonably possible but no longer than thirty (30) days following receipt of an advance copy of a Party’s proposed publication, the other Party informs such Party that its proposed publication contains Confidential Information of the other Party, then such Party shall delete such Confidential Information from its proposed publication. If, as soon as reasonably possible but no longer than thirty (30) days following receipt of an advance copy of a Party’s proposed publication, the other Party informs such Party that its proposed publication could be expected to have a material adverse effect on any Patents or Know-How of such other Party, then such Party shall delay such proposed publication for a period of reasonable length to permit the timely preparation and first filing of Patent application(s) on the information involved. For the avoidance of doubt, the provisions of this Section 4.3 are not intended to govern or limit submissions reasonably necessary for Regulatory Approvals, press releases, submissions in connection with the filing, prosecution and maintenance of Patents, and the like.

4.4 Publicity. Neither Party shall issue any press release or public announcement or disclosure relating to this Agreement or the terms hereof, the Research Program or any Products without the prior written approval of the other Party, which approval shall not be unreasonably withheld, except that a Party may issue such a press release or public announcement or disclosure if required by law, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or NASDAQ; provided that the other Party has received prior notice of such intended press release or public announcement or disclosure and the Party subject to the requirement includes in such press release or public announcement or disclosure only such information relating to the Product(s) or this Agreement as is required by such law. Without limiting the foregoing, each Party shall consult with the other Party on the provisions of this Agreement and the Research Plan, together with exhibits or other attachments attached thereto, to be redacted in any filings made by Genelabs and/or PHARMA with the Securities and Exchange Commission or as otherwise required by law. The rights of approval and notice granted to a Party in accordance with the preceding sentence shall only apply for the first time that specific information is to be disclosed, and shall not apply to the subsequent disclosure of substantially similar information that has previously been disclosed.

PAYMENTS; ROYALTIES AND REPORTS

5.1 Upfront Fee.

(a) Upon execution of this Agreement, PHARMA shall be obligated to make a one-time, non-refundable, non-creditable payment to Genelabs of US Four Million Dollars (US$4,000,000) in consideration for [**], payable within seven (7) days following receipt by PHARMA of an invoice in the form of Exhibit 5.1.

5.2 FTE Rate and Funding.

(a) FTE Rate. The “FTE Rate” shall mean the rate at which PHARMA will reimburse Genelabs during the Research Program Term to support one (1) Genelabs FTE in the Research Program. The FTE Rate will be US [**] Dollars (US$[**]) per FTE. The foregoing FTE Rate shall include all personnel, equipment, reagents and all other expenses including support staff, overhead and travel expenses for or associated with an FTE, provided that payment by PHARMA of the FTE Rate shall not be deemed to give PHARMA any ownership interest in any equipment, reagents or other property purchased by Genelabs using such research funding.

(b) FTE Funding. In consideration for Genelabs’ performance of its obligations under the Research Program, upon the terms and conditions contained herein, PHARMA shall reimburse Genelabs for the cost of each FTE provided by Genelabs pursuant to Section 2.3 at the FTE Rate. The amounts to be paid under this Section 5.2 shall be reimbursed by PHARMA quarterly in arrears, each installment equal to one-quarter of the FTE Rate multiplied by the actual number of FTEs devoted to the Research Program during the Calendar Quarter; provided that the FTE payment for (a) the first Calendar Quarter shall be prorated from the Effective Date and (b) the final Calendar Quarter during the Research Program Term shall be pro rated to the date of expiration or termination of the Research Program Term. Following the expiration of each Calendar Quarter during the Research Program Term, Genelabs shall provide to PHARMA an invoice substantially in the form of Exhibit 5.1 for all amounts due pursuant to this Section 5.2 for such Calendar Quarter in accordance with the Research Plan and detailed by activities performed by each FTE. Payments on such invoices shall be made within [**] days of PHARMA’s receipt of the applicable invoice.

5.3 Milestone Payments. As additional consideration for the licenses granted by Genelabs to PHARMA hereunder, PHARMA shall be obligated to pay to Genelabs the non-refundable, non-creditable (except as specifically provided in this Agreement or in Exhibit 5.3) milestone payments (whether such milestone is achieved by PHARMA, or its Affiliate or sublicensee under this Agreement) set forth on Exhibit 5.3 (“Milestone Payments”).

5.4 Payment of Milestone Payments.

(a) Subject to Section X5.3.4 in Exhibit 5.3, each of the Milestone Payments described in Exhibit 5.3 shall be payable [**]. For any Collaboration Compound, a Milestone Payment shall be payable upon the initial achievement of the applicable milestone and no amounts shall be due hereunder for subsequent or repeated achievement of such milestone by the same or any other Collaboration Compound.

(b) PHARMA shall notify Genelabs in writing within thirty (30) days upon the achievement of each milestone. After receipt of such notice (if applicable), Genelabs shall submit an invoice to PHARMA substantially in the form of Exhibit 5.1 with respect to the corresponding Milestone Payment. PHARMA shall make the Milestone Payment within [**] after receipt of such invoice.

5.5 Royalties.

(a) Royalties. As additional consideration for the licenses granted by Genelabs to PHARMA hereunder, subject to the terms and conditions of this Agreement, PHARMA shall pay to Genelabs a royalty on annual Calendar Year worldwide Net Sales of each Product [**] by PHARMA, its Affiliates and sublicensees, in accordance with the royalty rates set forth below:

[**]

(b) Royalty Term; Reduction in Rate. Royalties will be payable on a Product-by-Product and country-by-country basis until the later of (i) the expiration of the last to expire Valid Claim of (A) with respect to a Product containing a Genelabs Compound, Genelabs Patents covering the composition of matter of such Product, the use for which such Product is being sold in such country or the manufacture or formulation of such Product or (B) with respect to a Product containing a PHARMA Compound, PHARMA Patents covering the composition of matter of such Product or the use for which such Product is being sold in such country or (ii) ten (10) years from the First Commercial Sale of such Product in such country (“Royalty Term”); provided that for any period during the Royalty Term following the expiration of the last to expire Valid Claim described in clause (i) above, then the royalty applicable to Net Sales of the applicable Product in such country thereafter for the remainder of the Royalty Term for such Product in such country shall be reduced by [**]. Following the Royalty Term on a Product-by-Product and country-by-country basis, PHARMA’s licenses with respect to such Product shall continue in effect, but become fully paid-up, royalty-free, transferable, perpetual and irrevocable.

(c) Application of Royalty for Different Products. For the avoidance of doubt, the calculation of royalties under this Section 5.5 shall be conducted [**]. Thus, if PHARMA, its Affiliates, or sublicensees sell more than one Product in the Territory, any applicable thresholds and ceilings in this Section 5.5 shall [**]. For the purposes of this Section 5.5, any Products which contain as an active ingredient the same Collaboration Compound shall be considered one Product.

(d) Third Party Obligations. In the event PHARMA is required to obtain a license from any Third Party under any Patent or other intellectual property right of such Third Party and is obligated to pay a royalty to such Third Party or is liable for damages, license fees or other payments to such Third Party because PHARMA’s exercise of the license hereunder infringes or is alleged to infringe such Patent or other intellectual property rights of such Third Party, then, as between Genelabs and PHARMA, PHARMA shall in the first instance be responsible for such Third Party amounts owed, but shall have the right to deduct [**] of the amount of such royalties, damages, license fees and other payments (“Third Party Payments”) from any payments due for [**] and any royalties payable to Genelabs pursuant to this Agreement; provided, that in no event shall any credits or deductions under this Section 5.5(d) or any other provision of this Agreement in any Calendar Quarter exceed [**] of (i) the [**] against which the credit or deduction is being applied, or (ii) the aggregate royalties payable to Genelabs in such Calendar Quarter (such limits in (i) and (ii) shall be referred to as the “Agreed Limit”). Any portion of the Third Party Payments that PHARMA is entitled to deduct in accordance with the foregoing but which PHARMA is unable to deduct in any Calendar Quarter due to application of the Agreed Limit shall be rolled forward and deducted in the next Calendar Quarter for purposes hereof (subject to the Agreed Limit in such next Calendar Quarter) and so on until PHARMA has fully deducted Genelabs’ portion of such Third Party Payments. For the avoidance of doubt, nothing in this Section 5.5(d) shall be construed to prohibit PHARMA from pursuing any and all remedies available to it or recovering the full amount of damages sustained as a result of a breach by Genelabs of its representation and warranty set forth in Section 6.2(h).

(e) Genelabs Third Party Obligations. Notwithstanding Section 5.5(d), Genelabs shall remain responsible for the payment of all royalty and other obligations, if any, due to Third Parties under Genelabs Patents or Genelabs Know-How which are licensed to Genelabs and are sublicensed to PHARMA hereunder. All such payments shall be made promptly by Genelabs (but in any event within the time period required under the applicable license or other agreement). Genelabs will not be entitled to add such royalties due to Third Parties to the royalty rates set forth in Section 5.5(a).

(f) Substantial Generic Competition. In the event that substantial generic competition in the sale of a Product arises in any country, the royalties due in said country pursuant to this Agreement shall be reduced by [**]. Such reduction shall commence with the beginning of the first full Calendar Quarter following PHARMA’s written notification to Genelabs of the existence of such substantial generic competition. Substantial generic competition as used in this Section 5.5(f) shall mean that [**]. Such significant generic competition shall be measured using [**] of PHARMA, its Affiliates or sublicensees and those of the Third Party or Third Parties, as reported by IMS Health Incorporated (“IMS”) or another reputable, independent market research firm reasonably acceptable to both Parties.

5.6 Reports; Payment of Royalty. Within thirty (30) days after each Calendar Quarter during the term of this Agreement following the First Commercial Sale of a Product, PHARMA will provide to Genelabs the Sales Report. Genelabs shall submit an invoice to PHARMA

substantially in the form of Exhibit 5.1 with respect to the royalty amount set forth on such Sales Report. PHARMA shall pay such royalty amount [**] after receipt of such invoice.

5.7 Audits.

(a) Each Party shall keep complete, true and accurate books and records in accordance with its Accounting Standards in sufficient detail for the other Party to determine the payments due under this Agreement, including the royalties and FTE funding. Each Party will keep such books and records for at least three (3) years following the end of the fiscal year to which they pertain.

(b) During the term of this Agreement and for [**] thereafter, each Party (“Auditing Party”) shall have the right to appoint an independent, internationally recognized accounting firm (“Auditor”) to audit the relevant records of the other Party and its Affiliates (and, in the case of PHARMA, its sublicensees) which are authorized to sell Products or required to perform obligations of the Party pursuant to this Agreement (“Audited Party”) to confirm Net Sales, royalties, FTE funding and other payments for a period covering not more than the preceding [**]; provided, however, that the Auditor is reasonably acceptable to the Audited Party and before beginning its audit, executes an undertaking reasonably acceptable to the Audited Party by which the Auditor shall keep confidential all information reviewed during such audit. The Auditor shall have the right to disclose to the Auditing Party only its conclusions regarding the audit and not any of the information reviewed, which conclusions will remain Confidential Information of the Audited Party, subject to Section 4.

(c) The Audited Party shall make its records (and those of its Affiliates and sublicensees, as applicable) available for inspection by the Auditor during regular business hours at the facility(ies) of the Audited Party where such records are customarily kept, upon reasonable notice from the Auditing Party solely to verify the accuracy of the reports given and payments due under this Agreement. Such audit right may only be exercised once per Calendar Year by the Auditing Party and only once with respect to records covering any specific fiscal year.

(d) The Auditing Party shall bear the full cost of such audit, unless it discloses an underpayment of royalties or overbooking of FTE funding by the Audited Party of more than [**] of the amount of royalties or FTE funding due or incurred over the audited period, in which case, the Audited Party shall bear the full cost of such audit and shall promptly remit to the Auditing Party the amount of any underpayment of royalties or the amount due because of any overbooking of FTE funding, and PHARMA may credit against any subsequent Royalties due to Genelabs the amount of any overpayment of royalties.

5.8 Payments and Exchange Rate. Payments to each Party shall be made by electronic wire transfer of immediately available funds to the account of the Party, as designated in writing to the other Party. All payments under this Agreement shall be payable in US dollars. When conversion of payments from any foreign currency is required to be undertaken by PHARMA, such conversion shall be made using PHARMA’s then-current standard exchange rate

methodology as applied in its external reporting and consistent with PHARMA’s Accounting Standards.

5.9 Income Tax Withholding. Genelabs will pay any and all taxes levied on account of any payments made to it under this Agreement. If any taxes are required to be withheld by PHARMA, PHARMA will (a) deduct such taxes from the payment made to Genelabs, (b) timely pay the taxes to the proper taxing authority, and (c) send proof of payment to Genelabs and certify its receipt by the taxing authority promptly following such payment.

5.10 No Projections. Genelabs acknowledges and agrees that nothing in this Agreement shall be construed as representing an estimate or projection of either (a) the number of Collaboration Compounds or Products, if any, that may be successfully developed and/or commercialized or (b) anticipated sales of any Product, and that the milestones and Net Sales levels set forth in Sections 5.3, 5.4, 5.5 and Exhibit 5.3 or elsewhere in this Agreement or that have otherwise been discussed by the Parties are merely intended to define the Milestone Payments and royalty obligations to Genelabs in the event such milestones and/or Net Sales levels are achieved. PHARMA MAKES NO REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, THAT IT WILL BE ABLE TO SUCCESSFULLY DEVELOP AND/OR COMMERCIALIZE ANY COLLABORATION COMPOUND OR ANY PRODUCT OR, IF COMMERCIALIZED, THAT ANY PARTICULAR NET SALES LEVEL OF SUCH PRODUCT WILL BE ACHIEVED.

INDEMNIFICATION

10.1 Indemnification by PHARMA. PHARMA hereby agrees to indemnify, defend and hold Genelabs and its Affiliates, and their respective directors, officers, employees, contractors, agents and assigns (each, a “Genelabs Indemnitee”) harmless from and against any and all Third Party claims, suits, actions, demands, liabilities, investigations, proceedings, expenses and/or losses, including reasonable legal costs and attorneys’ fees (collectively, “Losses”), to which any Genelabs Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Person other than a Party or its Affiliates to the extent such Losses arise or result directly or indirectly out of: (i) the breach by PHARMA of any warranty, representation, covenant or agreement made by PHARMA in this Agreement, (ii) the actions of PHARMA or its Affiliates in connection with the research, development or commercialization of Collaboration Compounds or Products under this Agreement, or (iii) the negligence or willful or criminal misconduct of PHARMA or its Affiliates; except, in each case, to the extent such Losses result from the negligence or willful misconduct of any Genelabs Indemnitee or the breach by Genelabs of any warranty, representation, covenant or agreement made by Genelabs in this Agreement.

10.2 Indemnification by Genelabs. Genelabs hereby agrees to indemnify, defend and hold PHARMA and its Affiliates and their respective directors, officers, employees, contractors,

agents and assigns (each, a “PHARMA Indemnitee”) harmless from and against any and all Losses to which any PHARMA Indemnitee may become subject as a result of any claim, demand, action or other proceeding by any Person other than a Party or its Affiliates to the extent such Losses arise directly or indirectly out of: (i) the breach by Genelabs of any warranty, representation, covenant or agreement made by Genelabs in this Agreement, (ii) the actions of Genelabs or its Affiliates in connection with the research or development of Collaboration Compounds and/or Products under this Agreement or (iii) the negligence or willful or criminal misconduct of Genelabs or its Affiliates; except, in each case, to the extent such Losses result from the negligence or willful misconduct of any PHARMA Indemnitee or the breach by PHARMA of any warranty, representation, covenant or agreement made by PHARMA in this Agreement.

10.3 Control of Defense.

(a) Any Party or any of its Affiliates seeking indemnification hereunder (the “indemnified party”) shall notify the other Party (the “indemnifying party”) in writing reasonably promptly after the assertion against the indemnified party of any claim or allegation by a Third Party (a “Third Party Claim”) in respect of which the indemnified party intends to base a claim for indemnification hereunder, but the failure or delay so to notify the indemnifying party shall not relieve the indemnifying party of any obligation or liability that it may have to the indemnified party except to the extent that the indemnifying party demonstrates that its ability to defend or resolve such Third Party Claim is adversely affected thereby.

(b) (i) Subject to the provisions of Section 10.3(d) below, the indemnifying party shall have the right, upon written notice given to the indemnified party within thirty (30) days after receipt of the notice from the indemnified party of any Third Party Claim to assume the defense or handling of such Third Party Claim, at the indemnifying party’s sole expense, in which case the provisions of Section 10.3(b)(ii) below shall govern.

(ii) The indemnifying party shall select counsel reasonably acceptable to the indemnified party in connection with conducting the defense or handling of such Third Party Claim, and the indemnifying party shall defend or handle the same in consultation with the indemnified party, and shall keep the indemnified party timely apprised of the status of such Third Party Claim. The indemnifying party shall not, without the prior written consent of the indemnified party, agree to a settlement of any Third Party Claim which could lead to liability or create any financial or other obligation on the part of the indemnified party for which the indemnified party is not entitled to indemnification hereunder. The indemnified party shall cooperate with the indemnifying party and shall be entitled to participate in the defense or handling of such Third Party Claim with its own counsel and at its own expense. Notwithstanding the foregoing, in the event the indemnifying party fails to conduct the defense or handling of any Third Party Claim in good faith after having assumed such defense or handling, then the provisions of Section 10.3(c)(ii) below shall govern.

(c) (i) If the indemnifying party does not give written notice to the indemnified party, within thirty (30) days after receipt of the notice from the indemnified party of any Third Party Claim, of the indemnifying party’s election to assume the defense or handling of such Third Party Claim, the provisions of Section 10.3(c)(ii) below shall govern.

(ii) The indemnified party may, at the indemnifying party’s expense, select counsel in connection with conducting the defense or handling of such Third Party Claim and defend or handle such Third Party Claim in such manner as it may deem appropriate, provided, however, that the indemnified party shall keep the indemnifying party timely apprised of the status of such Third Party Claim and shall not settle such Third Party Claim without the prior written consent of the indemnifying party, which consent shall not be unreasonably withheld. If the indemnified party defends or handles such Third Party Claim, the indemnifying party shall cooperate with the indemnified party and shall be entitled to participate in the defense or handling of such Third Party Claim with its own counsel and at its own expense.

(d) If the indemnified party intends to seek indemnification hereunder, other than for a Third Party Claim, then it shall notify the indemnifying party in writing promptly after its discovery of facts upon which it intends to base its claim for indemnification hereunder, but the failure or delay so to notify the indemnifying party shall not relieve the indemnifying party of any obligation or liability that it may have to the indemnified party except to the extent that the indemnifying party demonstrates that the indemnifying party’s ability to defend or resolve such claim is adversely affected thereby.

10.4 Insurance. Each Party, at its own expense, shall maintain product liability insurance (or self-insure) in an amount consistent with industry standards during the term of this Agreement.

11.

MISCELLANEOUS

11.1 Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement when such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party including, but not limited to, embargoes, war, acts of war (whether war be declared or not), insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, earthquakes, tsunamis or other acts of God, or acts, omissions or delays in acting by any governmental authority or the other Party.

GENELABS ANNOUNCES COLLABORATION
FOR DEVELOPMENT AND COMMERCIALIZATION
OF HCV NON-NUCLEOSIDE DRUG CANDIDATES

REDWOOD CITY, Calif. – June 5, 2006 – Genelabs Technologies, Inc. (Nasdaq:GNLB) announced today that it has entered into a license and collaboration agreement with Novartis for the development and commercialization of compounds from Genelabs’ Hepatitis C Virus (HCV) non-nucleoside drug discovery program.

“I am delighted that Genelabs and Novartis are entering into this collaboration. This collaboration links us with a partner that has the scope, scale, expertise and commitment to make a major impact on the future treatment of HCV infection,” stated James A.D. Smith, President and Chief Executive Officer. “The Genelabs non-nucleosides covered by this collaboration have the potential to be complementary with other HCV drugs being developed by Novartis, and I believe Novartis is well positioned to move this project forward efficiently.”

Under the terms of the agreement, Genelabs is eligible to receive approximately $20 million over a planned two-year research program, including initial up-front payments of $12.5 million. If all potential clinical, regulatory and sales milestones are met, additional payments to Genelabs could exceed $175 million. Genelabs is also entitled to a royalty on net sales of products covered by the collaboration.

“This is the second major collaboration for Genelabs based on our HCV drug discovery platform, and we are very pleased to have Novartis as our partner,” stated Ronald C. Griffith, Ph.D., Chief Scientific Officer. “I am proud of the highly skilled and dedicated scientists working at Genelabs, who have all contributed to our HCV drug discovery successes.”

About the Hepatitis C Virus

Hepatitis C is a viral liver disease caused by infection with the Hepatitis C Virus. Worldwide, 170 million people are estimated to be infected with the hepatitis C virus. Liver disease resulting from chronic HCV infection is now recognized as the leading cause of liver failure and liver transplantation in the United States. Currently, there is no vaccine that can protect against HCV infection.

About the collaboration

Under the terms of the agreement, Genelabs is responsible for drug discovery research and Novartis is responsible for development and commercialization. Novartis has an option to extend the research funding for a third year and has a right of first negotiation for Genelabs’ HCV NS5a drug discovery compounds.

Lazard acted as financial advisor to Genelabs.

About Genelabs Technologies

Genelabs Technologies, Inc. is a biopharmaceutical company focused on the discovery and development of pharmaceutical products to improve human health. We have built drug discovery capabilities that can support various research and development projects. Genelabs is currently concentrating these capabilities on discovering novel compounds that selectively inhibit replication of the hepatitis C virus and advancing preclinical development of compounds from this hepatitis C virus drug discovery program, while also developing a late-stage product for lupus. We believe that these high-risk, potentially high reward programs focus our research and development expertise in areas where we have the opportunity to generate either first-in-class or best-in-class products that will address diseases for which current therapies are inadequate.
