Such credit shall be MERCK's sole remedy, and DOV's entire liability, for an Adverse FDA Decision. For purposes of this Section 5.4.3, an "Adverse FDA Decision" shall be defined as occurring in the event that a decision is made by the FDA as set forth in either clause (a) or (b) of this Section 5.4.3. (a) An Adverse FDA Decision shall be deemed to occur if MERCK submits data to the FDA for inclusion of a statement in the FDA-approved labeling of the Product as set forth in Section 5.4.1(a) or (b), and if, after MERCK exercises Commercially Reasonable Efforts to obtain the inclusion of a such a statement in the FDA-approved labeling of the Product, the FDA determines that the data presented by MERCK to support such a statement is not sufficient to support inclusion of such statement in the approved labeling for the Product. If MERCK obtains an Adverse FDA Decision pursuant to Section 5.4.3(a) relating to labeling as set forth in either Section 5.4.1(a) or (b), MERCK shall not be required to seek to publish or distribute advertisements or promotional labeling inconsistent with such Adverse FDA Decision. 23 [LOGO] Restricted Confidential Limited Access *** CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO THIS MATERIAL. (b) In addition to Section 5.4.3(a), an Adverse FDA Decision shall be deemed to occur if, after MERCK exercises Commercially Reasonable Efforts to publish or distribute advertisements or promotional labeling as set forth in Section 5.4.1(a) or (b), DDMAC objects to the inclusion of such statement in advertisements or promotional labeling, and if MERCK after exercising Commercially Reasonable Efforts to persuade DDMAC of the appropriateness of such statement, is unsuccessful in persuading DDMAC or other appropriate officials of the FDA to either (i) withdraw its objection, or (ii) state that it will not take enforcement action with regard to such statement in advertisements or promotional labeling as set forth in Section 5.4.1(a) or (b), or (iii) state that it will not take action against MERCK with respect to the continued use of such statement in advertisements or promotional labeling. 5.4.4 If, subsequent to receiving an Adverse FDA Decision pursuant to either Section 5.4.3(a) or (b), MERCK obtains data from Clinical Trials for a Product to support inclusion of the statements in Sections 5.4.1(a) or (b) based upon clinically significant data in either the FDA-approved label for the Product or promotional or advertising statements (as provided in Section 5.4.1(i) or (ii)), MERCK shall exercise Commercially Reasonable Efforts to either (i) obtain FDA approval for inclusion of a statement in the FDA-approved labeling of the Product as set forth in Section 5.4.1(a) or (b), or (ii) to publish or distribute advertisements or promotional labeling as set forth in Section 5.4.1(a) or (b). (a) In the event that, after receiving an Adverse FDA Decision, MERCK obtains FDA approval for inclusion of a statement in the FDA-approved labeling of the Product as set forth in Section 5.4.1(a) or (b), MERCK shall cease to take a credit against royalties as set forth in Section 5.4.3, and shall, within thirty (30) days of such FDA approval, refund to DOV the amount previously credited against royalties relating to such statement. (b) In the event that MERCK publishes or distributes advertisements or promotional labeling as set forth in Section 5.4.1(a) or (b) without obtaining FDA approval for inclusion of such statement in the FDA-approved labeling of the Product, and if MERCK does not receive an Adverse FDA Decision regarding the inclusion of such statements in advertisements or promotional labeling within six (6) months of the initial publication or distribution of such advertisements or promotional labeling, MERCK shall thereafter cease to take a credit against royalties as set forth in Section 5.4.3, and shall immediately upon the expiration of such six (6) month period refund to DOV the amount previously credited against royalties relating to such statement. 5.5 SALES MILESTONE PAYMENTS Subject to the terms and conditions of this Agreement, MERCK shall pay to DOV the following payments based on the achievement of the following milestones ("Sales Milestones"): (i) Upon achievement of worldwide Net Sales of Product in one Calendar Year of [***] dollars (US [***]) $US [***] (ii) Upon achievement of worldwide Net Sales of Product in one Calendar Year of [***] dollars (US [***]) $US [***] (iii) Upon achievement of worldwide Net Sales of Product in one Calendar Year of [***] dollars (US [***]) $US [***] 24 [LOGO] Restricted Confidential Limited Access *** CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO THIS MATERIAL. None of the payments attributable to Sales Milestones is refundable or creditable against any other payments or obligations of MERCK coming due and do not create any future performance obligations on the part of DOV. MERCK shall notify DOV in writing within thirty (30) days following the end of each Calendar Year in which a Sales Milestone is achieved, and shall make the appropriate payment within thirty (30) days after the end of the Calendar Year in which such Sales Milestone is achieved. The milestone payment shall be payable only upon the initial achievement of such Sales Milestone and no amounts shall be due hereunder for subsequent or repeated achievement of such Sales Milestone. For avoidance of doubt, each Sales Milestone is separately achievable, and the achievement of all Sales Milestone will yield aggregated payments by MERCK to DOV of $US [***]. If Net Sales of Product reach $US [***] in one year, a Sales Milestone payment of $US [***] will be due. If thereafter, Net Sales of Product reach $US [***] in a second year, a Sales Milestone payment of $US [***] will be due. If thereafter Net Sales of Product reach $US [***] in a third year, a Sales Milestone payment of $US [***] will be due. 5.6 ROYALTIES 5.6.1 ROYALTIES PAYABLE BY MERCK. Subject to the terms and conditions of this Agreement, MERCK shall pay DOV royalties, calculated on a Product-by-Product basis, as set forth in this Section 5.6.1. 5.6.1.1 PATENT ROYALTIES. For those countries where the sale of a Product by MERCK or its Related Parties would, but for either the existence of the license grants provided in Sections 3.1 and 3.2, or MERCK's Control of those MERCK Patent Rights claiming or covering compositions of matter of Product or Compound, infringe a Valid Patent Claim, MERCK shall pay royalties to DOV in an amount equal to the following percentage of Net Sales of Products: (a) [***] of worldwide Net Sales in each Calendar Year up to and including [***] dollars ($US [***]); (b) [***] of worldwide Net Sales in each Calendar Year for the portion of Net Sales exceeding [***] dollars ($US [***]), up to and including [***] dollars ($US [***]); (c) [***] of worldwide Net Sales in each Calendar Year for the portion of Net Sales exceeding [***] dollars ($US [***]), up to and including [***] dollars ($US [***]); and (d) [***] of worldwide Net Sales in each Calendar Year for the portion of Net Sales exceeding [***] dollars ($US [***]). 5.6.1.2 KNOW-HOW ROYALTY. In countries where the sale of Product would not result in a royalty payment obligation under Section 5.6.1.1, MERCK shall pay royalty rates that shall be set at [***] percent ([***]%) of the applicable royalty rate determined according to Section 5.6.1.1. 5.6.1.3 Royalty tiers pursuant to 5.6.1.1 and 5.6.1.2 shall be calculated based on worldwide Net Sales of each Product, provided that the determination of whether the royalty shall be calculated under 5.6.1.1 or 5.6.1.2 shall be determined on a country-by-country basis. Royalties on each Product at the rates set forth above shall continue on a country-by-country basis until the expiration of the later of: (i) the last-to-expire Valid Patent Claim; and (ii) ten (10) years after First Commercial Sale of such Product in such country (the "Royalty Period"). All royalties are subject to the following conditions: 25 [LOGO] Restricted Confidential Limited Access *** CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO THIS MATERIAL. (a) that only one royalty shall be due with respect to the same unit of Product; (b) that no royalties shall be due upon the sale or other transfer among MERCK or any Related Party, but in such cases the royalty shall be due and calculated upon MERCK's or the Related Party's Net Sales to the first Third Party; (c) that no royalties shall accrue on the sale or other disposition of Product by MERCK or its Related Parties for use in a Clinical Trial; and (d) that no royalties shall accrue on the disposition of Product in reasonable quantities by MERCK or its Related Parties as samples (promotion or otherwise) or as donations (for example, to non-profit institutions or government agencies for a non-commercial purpose). 5.6.2 CHANGE IN SALES PRACTICES. The Parties acknowledge that during the term of this Agreement, MERCK's sales practices for the marketing and distribution of Product may change to the extent to which the calculation of the payment for royalties on Net Sales may become impractical or even impossible. In such event the Parties agree to meet and discuss in good faith new ways of compensating DOV to the extent currently contemplated under Section 5.6.1. 5.6.3 ROYALTIES FOR BULK COMPOUND. In those cases where MERCK or a Related Party sells bulk Compound rather than Product to a Third Party, the royalty obligations of Section 5.6.1 shall apply to such sale of bulk Compound. 5.6.4 COMPULSORY LICENSES. If MERCK or a Related Party, as a condition of obtaining or maintaining Marketing Authorization in a country, is required to grant a compulsory license to a Third Party with respect to Product in any country in the Territory, and the royalty rate under such compulsory license is lower than the royalty rate provided by Section 5.6.1, then the royalty rate to be paid by MERCK on Net Sales under the applicable compulsory license in that country under Section 5.6.1 shall be reduced to the rate paid by the compulsory licensee. 5.6.5 THIRD PARTY LICENSES. In the event that one or more patent licenses from other Third Parties are required by MERCK or its Related Parties in order to make, have made, use, offer to sell, sell or import Compound (hereinafter "Third Party Patent Licenses"), [***] percent ([***]%) of the consideration actually paid under such Third Party Patent Licenses by MERCK or its Related Parties for sale of such Compound or Product in a country for a Calendar Quarter shall be creditable against the royalty payments due DOV by MERCK with respect to the sale of such Compound or Products in such country; provided, however, that in no event shall the royalties owed by MERCK to DOV for such Calendar Quarter in such country be reduced by more than [***] percent ([***]%). 5.7 REPORTS; PAYMENT OF ROYALTY. During the term of this Agreement following the First Commercial Sale of a Product, MERCK shall furnish to DOV a quarterly written report for the Calendar Quarter showing the Net Sales of all Products subject to royalty payments sold by MERCK and its Related Parties in the Territory during the reporting period and the royalties payable under this Agreement. Reports shall be due on the thirtieth (30th) day following the close of each Calendar Quarter. Royalties shown to have accrued by each royalty report shall be due and payable on the date such royalty report is due. MERCK shall keep complete and accurate records in sufficient detail to enable the royalties payable hereunder to be determined. 26 [LOGO] Restricted Confidential Limited Access *** CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO THIS MATERIAL. 5.8 AUDITS.

The accounting firm shall disclose to DOV only whether the royalty reports are correct or incorrect and the amount of any discrepancy. No other information shall be provided to DOV. (b) If such accounting firm correctly identifies a discrepancy made during such period, the appropriate Party shall pay the other Party the amount of the discrepancy within thirty (30) days of the date DOV delivers to MERCK such accounting firm's written report so correctly concluding, or as otherwise agreed upon by the Parties. The fees charged by such accounting firm shall be paid by DOV; provided, however, that if such audit uncovers a non-payment or an underpayment of milestone payments or royalties by MERCK during the audited period that exceeds the greater of [***] dollars ($US [***]) or percent ([***]%) of the total milestone payments or royalties owed, then the fees of such accounting firm shall be paid by MERCK. (c) MERCK shall include in each sublicense granted by it pursuant to this Agreement a provision requiring the sublicensee to make reports to MERCK, to keep and maintain records of sales made pursuant to such sublicense and to grant access to such records by DOV's independent accountant to the same extent required of MERCK under this Agreement. (d) DOV shall treat all financial information subject to review under this Section 5.8 or under any sublicense agreement in accordance with the confidentiality and non-use provisions of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality agreement with MERCK and/or its Related Parties obligating it to retain all such information in confidence pursuant to such confidentiality agreement. 5.9 PAYMENT EXCHANGE RATE. All payments to be made by MERCK to DOV under this Agreement shall be made in United States dollars and may be paid by check made to the order of DOV or bank wire transfer in immediately available funds to such bank account in the United States as may be designated in writing by DOV from time to time.

If, during the term of this Agreement MERCK reasonably demonstrates that the sale by prescription of a finished pharmaceutical product containing DOV 216,303 by DOV, Wyeth or any Affiliate or licensee of DOV or Wyeth has adversely affected MERCK's sales by prescription of DOV 21,947 for an Indication for which MERCK has obtained Marketing Authorization, upon MERCK's request the parties shall negotiate in good faith to determine either (i) a commercially reasonable amount of monetary compensation that DOV should pay MERCK, or (ii) any other reasonable adjustment of payments made under this Agreement, in either such case to compensate MERCK for such lost sales. The Parties agree that disputes arising under this Section 5.10 shall be governed by the dispute resolution procedures set forth in Section 12.6. 27 [LOGO] Restricted Confidential Limited Access 5.11 INCOME TAX WITHHOLDING. If laws, rules or regulations require withholding of income taxes or other taxes imposed upon payments set forth in this Article 5, MERCK shall make such withholding payments as may be required and shall subtract such withholding payments from the payments set forth in this Article 5.

With respect to all filings hereunder, the filing Party shall be responsible for payment of all costs and expenses related to such filings. 29 [LOGO] Restricted Confidential Limited Access 7.2 OPTION OF MERCK TO PROSECUTE AND MAINTAIN PATENTS. DOV shall give notice to MERCK of any desire to cease prosecution and/or maintenance of DOV Patent Rights on a country by country basis in the Territory and, in such case, shall permit MERCK, in its sole discretion, to continue prosecution or maintenance of such DOV Patent Rights at its own expense. If MERCK elects to continue prosecution or maintenance or to file based on DOV's election not to file pursuant to Section 7.1 above, DOV shall execute such documents and perform such acts at DOV's expense as may be reasonably necessary for MERCK to perform such prosecution or maintenance or filing on behalf of and in the name of DOV.

DOV's and MERCK's rights with respect to the initiation and prosecution of any legal action as a result of such certification or any recovery obtained as a result of such legal action shall be as defined in Sections 7.4.1 through 7.4.4 hereof; provided, however, that DOV shall exercise its first right to initiate and prosecute any action and shall inform MERCK of such decision within ten (10) days of receipt of the certification, after which time MERCK shall have the right to initiate and prosecute such action. 7.5 PATENT TERM RESTORATION, EXTENSION OR ADJUSTMENT. The Parties hereto shall cooperate with each other, including without limitation to provide necessary information and assistance as the other Party may reasonably request, in obtaining patent term restoration, extension or adjustment certificates or their equivalents in any country in the Territory where applicable to DOV Patent Rights or Joint Patent Rights.

For any Product or Compound, if the Party sponsoring the regulatory review thereof is not the owner of record of all patents eligible for patent term extension under 35 U.S.C. ss. 156, the Party sponsoring the regulatory review for Compound or Product shall inform the owner of record promptly of any regulatory approval that triggers the aforesaid obligation to apply for patent term extension. In the event that elections with respect to obtaining such patent term restoration, extension or adjustment are to be made, MERCK shall have the right to make the election and DOV agrees to abide by such election. 7.6 WYETH AGREEMENT. The Parties acknowledge that DOV's rights to prosecute and maintain DOV Patent Rights relating to DOV 216,303 are subject to the Wyeth Agreement, and that this Article 7 shall be interpreted and applied in a manner consistent with the relevant provisions of the Wyeth Agreement. 7.7 EFFECT OF CERTAIN TERMINATIONS.
