Each Commercialization Plan shall include the level of promotional and detailing effort necessary for Tanabe to at least achieve the forecast described in the Commercialization Plan. If (i) during either the ** or ** calendar years after the commercial launch of Tanabe Products in the Territory, Tanabe's unit sales of Tanabe Products are less than **, or (ii) during the ** calendar year after commercial launch of Tanabe Products or any calendar year thereafter, Tanabe's unit sales of Tanabe Products are less than **, and Tanabe's failure to achieve such unit sales of Tanabe Products is not due to **, then Genelabs shall have the option to convert any exclusive license under the Agreement for Tanabe Products into a non-exclusive appointment and license upon ninety (90) days prior written notice to Tanabe. If Genelabs converts the exclusive appointment and license under this Agreement to a non-exclusive license, then Tanabe hereby agrees to allow and cooperate in co-marketing of Tanabe Products in the Territory by Genelabs and/or designated Third Parties under Tanabe's regulatory approval for Tanabe Products and under the same Trademark (as such term is defined in Section 15.1) or Tanabe Trademark (as such term is defined in Section 15.3) used by Tanabe in the Territory. 5.3 ADVERSE DRUG EVENT REPORTING. Each party shall advise the other, by telephone or facsimile, within such time as is required to comply with Applicable Laws (but in any event promptly), after it becomes aware of any potentially serious or unexpected adverse event (including adverse drug experiences, as defined in 21 C.F.R. Section 314.80 or other applicable regulations) involving Tanabe Products' development, use or commercialization in the Territory (an "ADE"). Each party shall provide the other with a written report delivered by confirmed facsimile of any ADE, stating the full facts known to it, including but not limited to customer name, address, telephone number, batch, lot and serial numbers, and other information as required by Applicable Laws to the extent such ADE arises in the course of its development, use or commercialization of Tanabe Product or Prasterone Product in its respective territory (i.e. Japan for Tanabe, outside Japan for Genelabs). Each party shall have responsibility, with reasonable assistance from the other for (i) monitoring such ADE; (ii) data collection activities that occur between itself and the patient and medical professional, or that are provided to it by the other party, as appropriate, including any follow-up inquiries which it deems necessary or appropriate; and (iii) making any reports to the Competent Authorities in its respective territory.

Each party agrees to translate any non-English documents to be provided under this Section 5.3 to the other into English. Reasonably prior to the initiation of the clinical studies for the first Tanabe Product, the parties shall agree upon additional standard operating procedures for handling such ADE's in compliance with Applicable Laws. 5.4 INTERNATIONAL MARKETING STRATEGIES. Genelabs plans to hold periodic internal marketing strategy meetings to remain informed of any new plans or marketing studies to be conducted by Genelabs Licensees under Genelabs Patents and Genelabs Know-How for the manufacture, use and sale of Prasterone Products for the SLE indication ("Genelabs Licensees"). Furthermore, Genelabs agrees to use License and Collaboration Agreement (Prasterone) 13 ** CONFIDENTIAL TREATMENT REQUESTED commercially reasonable efforts to organize an international marketing strategy meeting involving Genelabs Licensees.

The Parties agree that the M&S Agreement (as such term is defined in Section 7.2) shall govern the management of any recall of a Tanabe Product. Notwithstanding the foregoing, in the event that Tanabe or the Regulatory Authority determines that a Tanabe Products recall or withdrawal in the Territory is necessary, then Tanabe shall take all actions appropriate in order to recall or withdraw such Tanabe Products. In case Tanabe determines that a Tanabe Products recall or withdrawal in the Territory is necessary without any decision of the Regulatory Authority, then it shall consult with Genelabs prior to taking any action with respect to the Tanabe Products. Genelabs shall reimburse Tanabe only for all reasonable out-of-pocket expenses (excluding any claimed loss of profits, prospective sales, goodwill or any other indirect loss) associated with any such recall or withdrawal caused in whole by the negligence of Genelabs or by Genelabs' failure to manufacture the Tanabe Products in accordance with the requirements of the M&S Agreement. Tanabe shall reimburse Genelabs only for all reasonable out-of-pocket expenses (excluding any claimed loss of profits, prospective sales, goodwill or any other indirect loss) associated with any such recall or withdrawal caused in whole by the negligence of Tanabe or by Tanabe's failure to comply with the terms and conditions of this Agreement or any applicable regulatory requirements. In the event that any Tanabe Products recall or withdrawal is caused in part by the negligence of Tanabe and in part by the negligence of Genelabs, the Parties' direct out-of-pocket expenses shall be apportioned between Genelabs and Tanabe in relation to each Party's respective negligent acts or omissions. 6. PAYMENT OBLIGATIONS. 6.1 INITIAL CONSIDERATION. (a) In consideration of the clinical supply and as reimbursement for the portion of FTE engaged in the ongoing development work, Tanabe shall pay to Genelabs two million dollars (U.S. $2,000,000) upon execution of this Agreement. This payment shall be non-refundable and non-creditable. Prior to payment of such amount by Tanabe, Genelabs will provide to Tanabe a written invoice regarding ongoing clinical development work in Prasterone Product by Genelabs FTEs. (b) Tanabe shall make the following equity investment ("Equity Investment") in Genelabs upon execution of this Agreement ("Investment Date") all in accordance with and subject to the terms and conditions of the stock purchase agreement to be entered into by the parties of even date herewith (the "Stock Purchase Agreement"): Tanabe shall purchase the number of shares purchasable with U.S. $2,600,000 with each share to be purchased at the price set forth in the Stock Purchase Agreement. (c) Tanabe shall issue irrevocable instructions to its bank to transfer by wire the initial consideration in Section 6.1(a) and the Equity Investment in Section 6.1(b), in accordance with Genelabs' written instructions, to Genelabs within twenty-four (24) hours after execution of this Agreement. The foregoing payment obligation is unconditional, and Tanabe shall not have any rights under this Agreement or under the Stock Purchase Agreement until such payment is received by Genelabs. 6.2 MILESTONE PAYMENTS. License and Collaboration Agreement (Prasterone) 14 ** CONFIDENTIAL TREATMENT REQUESTED (a) Tanabe shall make the following non-refundable, non-creditable milestone payments (the "Milestone Payments") to Genelabs within thirty (30) days after Tanabe's achievement of the applicable milestone for Tanabe Products set forth below.
Milestone Event Milestone Payment --------------- ----------------- Initiation of Pivotal/Bridging Study (i.e., Phase II/III) U.S. $2,000,000 in Japan Filing of NDA in Japan U.S. $2,000,000 National Health Insurance ("NHI") Price Listing in Japan U.S. $6,000,000 (subject to Section 6.2(b))
(b) Tanabe shall pay a non-refundable, non-creditable six million dollar (U.S. $6,000,000) milestone payment to Genelabs within thirty (30) days after a Tanabe Product has been added to the NHI Price List in Japan, provided however that if the MHLW only grants the indication of ** in the initial labeling for such Tanabe Product, such initial milestone payment shall be reduced to ** dollars (U.S. $**) or if only ** is granted in the initial labeling, such initial milestone payment shall be reduced to ** dollars (U.S. $**); provided however that if such initial labeling is subsequently expanded to include other indications (including, without limitation, ** in the event Tanabe only obtained initial labeling for ** or ** in the event that Tanabe only obtained initial labeling for **), Tanabe shall provide Genelabs with prompt written notice of such additional labeling right and pay to Genelabs the unpaid remainder of the U.S. $6,000,000 milestone for NHI price listing in Japan within thirty (30) days after obtaining such additional labeling right. For the avoidance of doubt, in all other circumstances except for the two expressly set forth above (i.e., Tanabe is only granted ** or ** in the initial labeling for Tanabe Products), Tanabe shall make the full NHI price listing milestone payment to Genelabs. Notwithstanding the foregoing potential initial milestone reduction, in the event that Tanabe elects, in its sole discretion pursuant to Section 2.3, to pursue the development and/or regulatory approval, including without limitation NHI listing, of only one indication referenced above (i.e., ** or **) under this Agreement, Tanabe shall provide Genelabs with prompt written notice of such election and Tanabe shall make the full NHI price listing milestone payment of six million dollars (U.S. $6,000,000) to Genelabs within thirty (30) days after achieving such milestone, regardless of the indication(s) is included in the labeling for the applicable Tanabe Product. 6.3 ROYALTIES.

(b) For the avoidance of doubt, the cumulative annual Net Sales for any given calendar year shall be reset to zero upon the beginning of the subsequent calendar year for purposes of applying the applicable royalty rate under Section 6.3(a). 6.4 ROYALTY PAYMENT TERMS. (a) Within fifteen (15) days after the end of each calendar month, Tanabe shall provide to Genelabs a written report setting forth (i) the calendar month covered by such report; (ii) a good faith estimate of the gross sales and Net Sales for such month; and (iii) the estimated accrued royalties for such month. The foregoing report shall cover sales activity by Tanabe, its Affiliates and Tanabe Sublicensees. (b) Payments due under Section 6.3 shall be payable within thirty (30) calendar days after the end of each calendar quarter with respect to Net Sales in such quarter. Each such payment shall be accompanied by a written report ("Quarterly Report") showing: (i) the calendar quarter for which such payment applies; (ii) the gross amount billed to Third Parties for Tanabe Products during such quarter; (iii) the total deductions from the amount billed to arrive at Net Sales; and (iv) the amount of royalties due under Section 6.2. The foregoing report shall cover sales activity by Tanabe, its Affiliates and Tanabe Sublicensees. Tanabe shall require its Sublicensees to prepare similar reports with respect to Sublicensee sales activities (excluding item (iv)) and Tanabe shall make such Sublicensee reports available to Genelabs upon request. Any late payments under this Agreement shall bear interest at a rate of prime plus two percent (2%) per annum, or the maximum rate permitted by law, whichever is less. (c) Tanabe's obligation to pay the full royalty amount to Genelabs under Section 6.3 shall begin with the first commercial sale of a Tanabe Product by Tanabe, its Affiliate or a Tanabe Sublicensee, and, subject to Section 6.5, continue until the end of the royalty term as set forth in Section 6.9. No reduction of the royalty amounts set forth in Section 6.3 shall occur unless and until, and solely in the event that, the conditions therefore under Section 6.5 are satisfied. 6.5 ROYALTY STEP-DOWN. (a) Provided that Tanabe's royalty obligations under Section 6.3 have not already been reduced under Section 6.5(b) (that is either Section 6.5(a) or (b) will apply to such royalty obligations, but not both), such royalty obligations shall be reduced by ** of what would otherwise be due pursuant to Section 6.3(a) (i.e., only ** of the royalty rates under Section 6.3(a) would apply to Net Sales) upon the occurrence of the later of (i) the expiration, disclaimer or final (unappealed or unappealable) determination of invalidity or unenforceability by a court or authority of competent jurisdiction of the last Valid Claim within the Genelabs Patents, Joint Patents or the Genelabs Improvement Patents in the Territory, or (ii) the expiration of the last to expire of any regulatory or data exclusivity period (i.e., saishinsa-kikan, including without limitation those exclusivities afforded through orphan designation). If reduced hereunder, such royalties shall remain at such reduced level for the remainder of the royalty term of this Agreement. License and Collaboration Agreement (Prasterone) 16 ** CONFIDENTIAL TREATMENT REQUESTED (b) Provided that Tanabe's royalty obligations under Section 6.3 have not already been reduced under Section 6.5(a) (that is either Section 6.5(a) or (b) will apply to such royalty obligations, but not both), Tanabe's royalty obligations under Section 6.3 with respect to Net Sales of Tanabe Products for SLE shall be reduced by ** of what would otherwise be due pursuant to Section 6.3(a) (i.e., only ** of the royalty rates under Section 6.3(a) would apply to Net Sales) upon the general commercial availability of a Competitive Product in the Territory; provided that, and only during the period during which, there exists no Valid Claim within the Genelabs Patents, Joint Patents or Genelabs Improvement Patents in the Territory. Tanabe shall continue to pay royalties under Section 6.3(a) at this reduced rate for as long as (but only for so long as) such Competitive Product remains on the market in the Territory. For purposes of this Section 6.5(b), "Competitive Product" shall mean a Prasterone Product, developed and commercialized by a Third Party who is not a Tanabe Sublicensee or an Affiliate, collaborator or other licensee of Tanabe, which Prasterone Product has received Regulatory Approval for the treatment of a SLE indication and the sales of which have a significant adverse impact upon the sales of Tanabe Products in the Territory. 6.6 CURRENCY OF PAYMENT. All payments to be made under this Agreement shall be made in U.S. Dollars. Net Sales shall be first determined in Japanese Yen and shall be converted quarterly into an amount in U.S. Dollars at the average of the bid and ask prices reported in the Wall Street Journal as of the close of the last business day of such quarter in which such royalty is due. 6.7 SINGLE ROYALTY. No multiple royalties or payments related to Net Sales shall be payable hereunder because the relevant Tanabe Product, its manufacture, sale or use is covered by more than one Valid Claim within the Genelabs Patents or Genelabs Improvement Patents. 6.8 TAXES. Each party shall be responsible for and pay all taxes, duties and levies directly imposed by all foreign, federal, state, local or other taxing authorities (including, without limitation, export, sales, use, excise, and value-added taxes) based on such party's transactions or payments under this Agreement, other than taxes imposed or based on the other party's net income. In the event that Tanabe is prohibited by law from remitting payments to Genelabs unless Tanabe deducts or withholds taxes therefrom on behalf of the local taxing jurisdiction, then Tanabe shall: (a) deduct those taxes from the otherwise remittable payments, (b) timely pay the taxes to the proper tax authority in accordance with applicable law, and (c) give Genelabs any reasonable assistance, which shall include the provision of such documentation as may be required by the tax authority to enable Genelabs to claim exemption from or obtain a tax credit, repayment of or reduction of tax. All taxes levied on a party's net income arising from the effect of this Agreement shall be borne by such party. 6.9 ROYALTY TERM. Tanabe's royalty obligations under Section 6.3 shall terminate upon the later of (i) the expiration, disclaimer or final (unappealed or unappealable) determination of invalidity or unenforceability by a court or authority of competent jurisdiction of the last Valid Claim within the Genelabs Patents, Joint Patents, or Genelabs Improvement Patents in the Territory which, absent rights hereunder, would be infringed by the development, manufacture, use, importation, sale or offer for sale of Tanabe Products or (ii) ten (10) years after the first commercial launch of a Tanabe Product. Notwithstanding the above, (a) Tanabe shall be obligated after expiration of the royalty term to pay any License and Collaboration Agreement (Prasterone) 17 ** CONFIDENTIAL TREATMENT REQUESTED royalty amounts that accrued under Section 6.3 prior to such expiration, and (b) after expiration of the ten (10)-year period following the first commercial launch of a Tanabe Product, if for purposes of the foregoing clause (i), the only unexpired, non-disclaimed, valid and enforceable Valid Claim(s) (as described in clause (i)) is within the Joint Patents and not within the Genelabs Patents or the Genelabs Improvement Patents, then Tanabe's royalty obligations shall be reduced by ** of what would otherwise be due pursuant to Section 6.3(a) or 6.5(b). For the avoidance of doubt, if the foregoing Section 6.9(b) event and Section 6.5(b) event occurs, then Tanabe's royalty obligations shall be ** of what would otherwise be due pursuant to Section 6.3(a). 7. SUPPLY OBLIGATIONS. 7.1 SUPPLY OF API AND PRASTERONE PRODUCT FOR PRE-CLINICAL AND CLINICAL USE. (a) Genelabs shall supply Tanabe with API and Prasterone Product in capsule form reasonably necessary for Tanabe to conduct any pre-clinical studies, formulation development and clinical studies required to obtain Regulatory Approval for Tanabe Products in the Territory at Genelabs' cost, which is included in the Initial Consideration set forth in Section 6.1(a); provided however that Genelabs' obligation to supply API and Prasterone Product in capsule form under this Section 7.1(a) shall not exceed in the aggregate five hundred kilograms total of API (500 kg total), with Prasterone Product not to exceed 10% of the total API. (b) Unless otherwise agreed to in writing by the parties, all deliveries by Genelabs of API hereunder shall be F.C.A. Genelabs' or its Third Party subcontractor's facility (Incoterms 2000) by means of a common carrier reasonably designated by Tanabe or, in the absence of Tanabe's designation, to a common carrier reasonably chosen by Genelabs. Tanabe shall bear the risk of loss to any units of API and/or Prasterone Product in capsule form from the F.C.A. point of delivery (at which point all title to such API shall pass to Tanabe). Tanabe shall be responsible for all risk and expense (including without limitation all delivery, freight, handling, taxes, tariffs, duties and insurance related expenses) after the deliveries made by Genelabs to Tanabe under this Section 7.1; for the avoidance of doubt, however, in no event shall Tanabe be required to pay any amounts to Genelabs that have already been paid by Tanabe pursuant to Section 7.2(a) and/or 7.2(b). 7.2 SUPPLY OF API AND PRASTERONE PRODUCT FOR COMMERCIAL EFFORTS. Within twelve (12) months of the Effective Date, Tanabe and Genelabs shall negotiate in good faith and enter into a manufacturing and supply agreement ("M&S Agreement") for the supply of API and/or Prasterone Product, polymorphic form 1 in 50mg capsules, to or for Tanabe by Genelabs for commercial purposes, containing the following terms and such other reasonable terms and conditions as the parties may mutually agree: (a) Genelabs shall provide for the manufacture of and supply to Tanabe, and Tanabe shall purchase from Genelabs, API on such time schedules as are agreed upon by the parties in the M&S Agreement at a price equaling the sum of ** thereof. (b) If Tanabe intends to sell as Tanabe Products the capsule forms of Prasterone Products developed by Genelabs, Genelabs shall, at Tanabe's request, provide for the manufacture of and supply to Tanabe, and Tanabe shall purchase from Genelabs, Prasterone Product in capsule form for Tanabe's commercial use as Tanabe Products in such quantities and on such time schedules agreed upon by the parties in the M&S Agreement at a price equaling the sum of ** thereof. License and Collaboration Agreement (Prasterone) 18 ** CONFIDENTIAL TREATMENT REQUESTED (c) Each party shall have the right to terminate the M&S Agreement upon the termination of Tanabe's royalty obligations as provided in Section 6.9; provided however, that Genelabs shall use reasonable efforts to facilitate Tanabe's securing an alternative supply source for Tanabe Product in the event of such termination of the M&S Agreement. (d) The M&S Agreement will include other provisions customarily found in agreements for products of similar nature, as mutually and reasonably agreed upon by the parties. (e) Upon the initiation of negotiations by the parties of the M&S Agreement, Tanabe shall propose, subject to Genelabs' reasonable approval, a reasonable, initial written forecast of estimated purchases of API and, if applicable, Prasterone Product in capsule form over the next five (5) years for purposes of setting Genelabs' manufacturing capacity. For the avoidance of doubt, this forecast shall be for facility and material planning purposes only and shall not constitute a firm order.

(a) Tanabe is knowledgeable, sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in shares presenting an investment decision like that involved in the purchase of the Purchased Shares, including investments in securities issued by companies comparable to Genelabs; (b) Tanabe acknowledges that it has reviewed the Disclosure Materials and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Genelabs concerning the terms and conditions of the offering of the Purchased Shares and the merits and risks of investing in such shares; (ii) access to information about Genelabs and the Subsidiaries and their financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that Genelabs possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment; (c) Tanabe is acquiring the Purchased Shares for its own account for investment only and with no present intention of distributing any of such shares or any arrangement or understanding with any other persons regarding the distribution of such Shares; (d) Tanabe understands that the Purchased Shares it is purchasing are "restricted securities" under the federal securities laws inasmuch as they are being acquired from Genelabs 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 Securities Act only in certain limited circumstances. In this connection Tanabe represents that it is familiar with Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act; (e) Tanabe qualifies as an "accredited investor" within the meaning of Rule 501 of Regulation D promulgated under the Securities Act; and (f) It is understood that the certificates evidencing the Purchased Shares shall bear the following legend: "These securities have not been registered under the Securities Act of 1933, as amended (the "Act"). 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, if requested by Genelabs, an opinion of counsel reasonably satisfactory to Genelabs and its counsel, that such registration is not required under such Act." 4.2 Due Execution, Delivery and Performance of the Agreement.

Upon the execution and delivery of this Agreement, this Agreement shall constitute a valid and binding obligation of Tanabe enforceable in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' and contracting parties' rights generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 4.3 Shareholders Meetings. (a) Quorum. For so long as Tanabe and its affiliates hold the Securities they shall vote all of the Purchased Shares in any and all meetings of the shareholders of Genelabs. (b) Voting. For a period of two (2) years from the date hereof, Tanabe and its affiliates shall vote all of the Purchased Shares for any and all proposals submitted by Genelabs to the vote of its shareholders, including but not limited to the election of directors, in accordance with the recommendations of the Board of Directors of Genelabs, or any committee thereof, to the shareholders with respect to such proposals. 4.4 Purchase of Voting Securities. For a period of two (2) years from the date hereof, Tanabe and its affiliates shall not, in the aggregate, purchase, acquire or beneficially own, or offer or agree to purchase, acquire or beneficially own, directly or indirectly, or alone or in concert with others, by purchase, gift, or otherwise, an aggregate of nineteen and nine-tenths percent (19.9%) or more of any class of voting securities of Genelabs, or any successor to or affiliate of Genelabs by merger, consolidation, sale of assets, combination or otherwise. 4.5 Transfer of Purchased Shares. For a period of two (2) years from the date hereof, Tanabe and its affiliates agree that, without the prior written consent of Genelabs, they (a) will not, directly or indirectly, offer, sell, agree to offer or sell, solicit offers to purchase, grant any call option or purchase any put option with respect to, pledge, borrow or otherwise dispose of any of the Purchased Shares, and (b) will not establish or increase any "put equivalent position" or liquidate or decrease any "call equivalent position" with respect to the Purchased Shares (in each case within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder), or otherwise enter into any swap, derivative or other transaction or arrangement that transfers to another, in whole or in part, any economic consequence of ownership of the Purchased Shares, whether or not such transaction is to be settled by delivery of the Purchased Shares, other securities, cash or other consideration. 5. Registration Rights 5.1 Certain Definitions. As used in this Section, the following terms shall have the following respective meanings: (a) "Registration Expenses" shall mean all expenses incurred in complying with registrations, filings or qualifications under Sections 5.2 and 5.3 hereof, including, without limitation, all registration, qualification and filing fees, accounting fees, printing expenses, escrow fees, fees and disbursements of counsel for Genelabs, blue sky fees and expenses, the expense of any special audits incident to or required by any such registration (but excluding the compensation of regular employees of Genelabs and Selling Expenses), and fees and expenses of one special counsel, if any, for the Tanabe not to exceed $25,000. (b) "Selling Expenses" shall mean all underwriting discounts and selling commissions applicable to the sale, inclusive of all fees and disbursements of counsel for Tanabe (excluding amounts to be paid to one special counsel for Tanabe under Registration Expenses). 5.2 Piggyback Registration. (a) Triggering Event. The rights described in this Section 5.2 shall be available to Tanabe on and after the second anniversary of the date of this Agreement if and only if (i) Tanabe shall desire to sell some or all of the Purchased Shares, (ii) Tanabe shall contact one or more reputable brokerage or investment banking firms to assist Tanabe in executing such sale, and (iii) Tanabe shall be advised by such firms (and provide reasonable evidence of such advice to Genelabs) that the stock price, trading commission and trading execution terms available to Tanabe in selling the Purchased Shares are not substantially similar to the price, commission and terms that would be available to any other person seeking to sell a similar number of shares that are registered under the Securities Act of 1933. (b) Registration. Provided that the rights provided hereunder are available under the provisions of Section 5.2(a), if at any time or from time to time, Genelabs shall determine to register any of its securities, either for its own account or the account of a security holder or holders exercising their respective demand registration rights, other than a Special Registration Statement, which shall mean: (i) a registration on Form S-8 (or a similar or successor form) relating solely to employee stock option, stock purchase or other benefit plans, or (ii) a registration on Form S-4 (or similar or successor form) relating solely to a Commission Rule 145 transaction, Genelabs will: (i) promptly give to Tanabe written notice thereof; and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Purchased Shares specified in a written request or requests, made by Tanabe within twenty (20) days after mailing of written notice by Genelabs. (c) Underwriting. If the registration of which Genelabs gives notice is for a registered public offering involving an underwriting, Genelabs shall so advise Tanabe as a part of the written notice given pursuant to Section 5.2(b)(i). In such event the right of Tanabe to registration pursuant to Section 5.2 shall be conditioned upon Tanabe's participation in such underwriting and the inclusion of Tanabe's Purchased Shares in the underwriting to the extent provided herein. Tanabe shall (together with Genelabs and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the underwriter ("Underwriter's Representative"). Notwithstanding any other provision of this Section 5.2, if the Underwriter's Representative determines that marketing factors require a limitation of the number of shares to be underwritten, the underwriter may limit the number of Purchased Shares to be included in the registration and underwriting and such number shall be allocated, first, to Genelabs, second to Tanabe and other holders who have registration rights electing to participate in such underwriting, on a pro rata basis based on the total number of shares held by Tanabe and such participating holders, and, third, to any other shareholder of Genelabs on a pro rata basis. If Tanabe disapproves of the terms of any such underwriting, Tanabe may elect to withdraw therefrom by written notice to Genelabs and the Underwriter's Representative. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. 5.3 Expenses of Registration. All Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to Sections 5.2 shall be borne by Genelabs; and, unless otherwise stated, all Selling Expenses relating to shares registered by Tanabe shall be borne by Tanabe on the basis of the number of shares so registered. 5.4 Registration Procedures. In the case of each registration, qualification or compliance effected by Genelabs pursuant to this Section 6, Genelabs will keep Tanabe advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. Genelabs will as expeditiously as reasonably possible: (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 for a period of one hundred twenty (120) days or until Tanabe has completed the distribution described in the registration statement relating thereto, whichever occurs first. (b) Furnish to Tanabe and to each underwriter such number of copies of the registration statement and the prospectus included therein (including each preliminary prospectus) as such persons may reasonably request in order to facilitate the intended disposition of the Purchased Shares covered by such registration statement. (c) Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in paragraph (a) above. (d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by Tanabe; provided that Genelabs shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions. (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the Underwriter's Representative of such offering. Tanabe shall also enter into and perform its obligations under such an agreement. (f) Notify Tanabe at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. Genelabs will use reasonable efforts to amend or supplement such prospectus in order to cause such prospectus not to include any 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 light of the circumstances then existing. (g) Use its best efforts to furnish, on the date that such Purchased Shares are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of such date, of the counsel representing Genelabs 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 (ii) a letter dated as of such date, from the independent certified public accountants of Genelabs, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering addressed to the underwriters. (h) Cause all such Purchased Shares registered pursuant hereto to be listed on each securities exchange on which similar securities issued by Genelabs are then listed; or, if not previously listed on any exchange, then cause all such Purchased Shares to be listed on the New York Stock Exchange, American Stock Exchange or the NASDAQ National Market System. (i) Provide a transfer agent and registrar for all Purchased Shares registered pursuant hereunder and a CUSIP number for all such Purchased Shares, in each case not later than the effective date of such registration. 5.5 Indemnification. (a) To the extent permitted by law, Genelabs will, and does hereby undertake to, indemnify and hold harmless Tanabe, each of its officers, directors and partners, and each person controlling Tanabe within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this Section 5, and each underwriter, if any, and each person who controls any underwriter within the meaning of Section 15 of the Securities Act, against all expenses, claims, losses, damages and liabilities (or actions in respect thereof), including settlement of any litigation, commenced or threatened, to which they may become subject under the Securities Act, the Exchange Act, or other federal or state law, arising out of or based on compliance with, any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus (preliminary or final), offering circular or other document or amendments thereto, or arising out of or based on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or arising out of or any violation by Genelabs of any federal, state or common law rule or regulation applicable to Genelabs and relating to action or inaction required of Genelabs in connection with any such registration, qualification or compliance, and will reimburse Tanabe, each of its officers, directors and partners, and each person controlling Tanabe, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that Genelabs will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to Genelabs by an instrument executed by Tanabe or underwriter expressly for use in connection with such registration. (b) To the extent permitted by law, Tanabe will, if Purchased Shares held by Tanabe are included in the securities as to which such registration, qualification or compliance is being effected, indemnify and hold harmless Genelabs, each of its directors and officers, agents and employees, each underwriter, if any, of Genelabs' securities covered by such a registration statement, each person who controls Genelabs or such underwriter within the meaning of Section 15 of the Securities Act, and Tanabe, each of its officers, directors and partners and each person controlling Tanabe within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions in respect thereof to which they may become subject) arising out of or based on any of the following: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by Genelabs of the Securities Act (collectively, a "Holder Violation"), in each case to the extent (and only to the extent) that such Holder Violation occurs in reliance upon and in conformity with written information furnished by Tanabe under an instrument duly executed by Tanabe and stated to be specifically for use in connection with such registration; and Tanabe will reimburse any legal or other expenses reasonably incurred by Genelabs or any such director, officer, controlling person, or underwriter in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that the indemnity agreement contained in this Section 5.5(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of Tanabe, which consent shall not be unreasonably withheld; provided further, that in no event shall any indemnity under this Section 5.5 exceed the net proceeds from the offering received by Tanabe. (c) Each party entitled to indemnification under this Section 5.5 (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall deliver written notice to the Indemnifying Party of commencement thereof. The Indemnifying Party, at its sole option, may participate in or assume the defense of any such claim or any litigation resulting therefrom with counsel reasonably satisfactory to the Indemnified Party, and the Indemnified Party may participate in such defense at Indemnified Party's expense. The failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 6 except to the extent that such failure to give notice shall materially adversely affect the Indemnifying Party in the defense of any such litigation. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term a release from all liability in respect to such claim or litigation by the claimant or plaintiff to such Indemnified Party. (d) If the indemnification provided for in this Section 5.5 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, that in no event shall any contribution by Tanabe hereunder exceed the net proceeds from the offering received by Tanabe. (e) The obligations of Genelabs and Tanabe under this Section 5.5 shall survive completion of any offering of Purchased Shares in a registration statement and the termination of this Agreement. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 5.6 Information From Tanabe. Tanabe shall furnish to Genelabs such information regarding Tanabe and the distribution proposed by Tanabe as Genelabs may reasonably request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Section 5. 5.7 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Purchased Shares to the public without registration, Genelabs agrees to: (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act at all times; (b) File with the Commission in a timely manner all reports and other documents required of Genelabs under the Securities Act and the Exchange Act; and (c) Furnish Tanabe forthwith upon request a written statement as to its compliance with the reporting requirements of Rule 144, and of its compliance with the Securities Act and the Exchange Act; Genelabs shall provide forthwith upon written request a copy of the most recent annual or quarterly report of Genelabs, and such other reports and documents of Genelabs as Tanabe may reasonably request in availing itself of any rule or regulation of the Commission allowing Tanabe to sell any such Purchased Shares without registration. 5.8 Assignment of Registration Rights. The rights to cause Genelabs to register the Purchased Shares and related rights granted Tanabe under Section 5 may be assigned to any transferee upon a transfer of any Purchased Shares; provided, that Genelabs receives notice of such assignment, and the transferee agrees to be bound by the registration rights provisions in Section 5 of this Agreement. 6. Survival of Representations, Warranties and Agreements. Notwithstanding any investigation made by any party to this Agreement, all covenants, agreements, representations and warranties made by Genelabs and Tanabe herein shall survive the execution of this Agreement, the delivery to Tanabe of the Purchased Shares being purchased and the payment therefor, except to the extent otherwise provided herein. 7.
