     (a)

               (i) Prior to the Effective Date, Santarus has advanced to S2 an amount equal to Seven Hundred Fifty Thousand Dollars ($750,000.00) (the “Advance”).

               (ii) Within [***] ([***]) business days of the Effective Date, in partial consideration of the rights granted to Santarus under this Agreement and to fund or reimburse S2 and VeroScience for research and development activities with respect to the Product, Santarus shall pay to (i) S2 an additional amount equal to [***] Dollars ($[***]) (subject to Section 7.1(a)(iv) below) and (ii) VeroScience an amount equal to [***] Dollars ($[***]) (collectively, with the Advance, the “Initial Fee”).

               (iii) Within [***] ([***]) business days of receipt of the Initial Fee, VeroScience shall pay the outstanding amounts due to FDA in the approximate amount of [***] Dollars ($[***]).

               (iv) Notwithstanding the foregoing subsection (a)(ii), Santarus may withhold from the portion of the Initial Fee to be paid to S2 an amount equal to [***] ($[***])

until such time as the Deposit Bank is established. Within [***] ([***]) business days of the establishment of the Deposit Bank, Santarus shall pay to the Deposit Bank to hold in the Joint Account an amount equal to [***] ($[***]), which VeroScience and S2 shall instruct the Deposit Bank to pay out to satisfy their obligations under Section 4.7, Section 7.4 and Article V of this Agreement, including, without limitation, amounts due and owing with respect to Third Party costs and expenses associated with pharmacovigilance, medical affairs and Adverse Drug Experience reporting, annual reports filed in connection with the NDA and user fees and establishment fees associated with the NDA (“Regulatory Amounts”) that will are incurred from the Effective Date through December 31, 2010 or are incurred by S2 or VeroScience as of the Effective Date.

The Royalty True-Up shall be calculated at the end of the calendar year and Santarus shall pay to S2 and VeroScience such Royalty True-Up in accordance with Schedule 7.1(b) within ninety (90) days after the end of any applicable calendar year.

     (c) [***]

     (d) Within [***] ([***]) business days following the end of each [***] during the Term, Santarus shall provide S2 and VeroScience with a statement in a mutually agreeable format setting forth:

               (i) the aggregate number of units of the Product invoiced and recognized as sales to customers in the Territory during such Agreement Month;

Statements required to be provided to S2 and VeroScience under this Section 7.1 shall be emailed to such email addresses as S2 and VeroScience may from time to time designate in writing.

     (f) In the event that payments due to S2 or VeroScience under this Agreement for a particular period would be a negative number, neither S2 nor VeroScience will be required to make a payment to Santarus for such period, but such negative number shall be credited against future payments due to S2 and VeroScience hereunder; provided that upon expiration or termination of this Agreement (except in the event of a termination by S2 or VeroScience pursuant to Section 8.3), S2 or VeroScience, as applicable, shall promptly pay to Santarus any aggregate negative amounts which were to be credited as provided hereunder but in no event later than thirty (30) days following the Final Agreement Quarter.

     (g) In the event adjustment(s) to Gross Margin are made more than [***] ([***]) business days subsequent to the end of an Agreement Month, such adjustment(s) will be applied to the following Agreement Month and may result in an adjustment to the payment for such Agreement Quarter.

     (h) For clarity, as between the parties, S2 or VeroScience shall be solely responsible for any fees or payments required under the Upstream Agreements. Santarus shall have no responsibility for any such fees or payments.

     7.2 Maintenance of Records

     (a) Santarus agrees to keep, for a period of at least [***] ([***]) years after the date of entry (or such longer period as may be required by Legal Requirements) full and accurate records maintained in accordance with Santarus’ accounting practices in sufficient detail to enable a Third Party to accurately calculate COGS, Gross Margin and Net Sales reported, and payments to be made under this Agreement. Upon [***] ([***]) days prior written notice, such records shall be made available by Santarus for audit by an independent certified public accounting firm designated by S2 and VeroScience and reasonably acceptable to Santarus. The auditor will only examine such books and records during business hours but not more than [***] while this Agreement remains in effect and for [***] ([***]) years thereafter in order to verify COGS, Gross Margin, Net Sales or payments due under this Agreement. The fees and expenses

of the auditor performing such verification examination shall be borne by S2 and VeroScience; provided, however, that if any verification reveals that Santarus has reported incorrectly, and the amount of such discrepancy is at least [***] percent ([***]%) of the aggregate amount that should have been reported for the period examined, then Santarus shall pay the entire amount of the fees and expenses for such verification. This right to audit shall extend throughout the Term and for [***] after expiration or termination of this Agreement.

     (b) Santarus shall have the right, upon [***] ([***]) business days’ prior written notice, to audit all applicable records of each other party for the purpose of determining such other party’s compliance with the obligations set forth in this Agreement. The audit will be conducted during normal business hours, at convenient times. Any such audit may be conducted no more than [***]. The fees and expenses of any such audit shall be borne by Santarus. This right to audit shall extend throughout the Term and for [***] after expiration or termination of this Agreement.

     (c) Whenever in this Agreement a party is required to report its costs, or is entitled to receive or obligated to make a payment based on its costs, such costs shall be determined in accordance with generally accepted accounting principles as applied in the United States (“GAAP”), consistent with the terms of this Agreement. The term “out-of-pocket” costs or expenses means cost or expenses paid to Third Parties and shall not include any fixed costs or expenses, personnel costs or expenses, overhead costs or expenses, or other costs or expenses of a similar nature.

     (d) Each of S2 and VeroScience shall prepare, at its sole cost and expense, unaudited financial statements (including an income statement, balance sheet and a statement of cash flow) in accordance with S2 and VeroScience’s standard accounting principles, as applicable, and GAAP, consistently applied, subject to normal year-end audit adjustments [***], on a quarterly and on an annual basis each calendar year during the Term. Such financial statements shall be provided to each of the other parties within [***] ([***]) days after each of the first three (3) calendar quarters of each calendar year and within [***] ([***]) days after the end of each calendar year.

     7.3 Payments

     Any payments required to be made under this Agreement shall be made in United States dollars via wire transfer of immediately available funds to such bank account as the other party shall designate in writing prior to the date of such payment. All payments shall bear interest from the date due until paid at a rate equal to the prime rate effective for the date that payment was due, as quoted by the Wall Street Journal, New York Edition, on the date such payment was due, plus [***] percent ([***]%), or, if less, the maximum rate permitted by applicable law.

     7.4 Expenses

     Except as otherwise agreed between the parties or set forth in this Agreement, each party will bear its own operating expenses associated with the Product and Commercialization

and Promotion thereof, including all personnel, general and administrative and overhead costs. As between the parties, (a) Santarus will bear all Santarus Sales Force expenses and costs associated with its Promotion in the Territory and its Manufacturing for Commercialization in the Territory (provided that S2 and VeroScience will share in certain of these costs as a function of the Gross Margin split pursuant to Section 7.1(b)), and (b) VeroScience or S2 will bear all costs associated with Development of the Product, and with maintaining and continuing all Regulatory Approvals, in each case, in the Territory, including all Regulatory Amounts.

ARTICLE VIII
TERM AND TERMINATION

     8.1 Term

     The term of this Agreement shall commence on the Effective Date and shall continue, unless terminated sooner in accordance with this Article VIII, until Santarus ceases to market or sell the Product in the Territory (the “Term”).

     8.2 Early Termination

     (a) Santarus may terminate this Agreement on the first anniversary of the first sale for use, consumption or resale of the Product to a Third Party in a bona fide arm’s-length transaction in the Territory following the Promotion Commencement Date (“First Commercial Sale”) upon at least sixty (60) days’ prior written notice to S2 and VeroScience.

     (b) After the first anniversary of the First Commercial Sale, Santarus may terminate this Agreement for any reason upon one hundred twenty (120) days’ prior written notice to S2 and VeroScience.

     (c) Santarus may terminate this Agreement immediately upon written notice to S2 and VeroScience in the event of (i) any action taken or objection raised by any Governmental Authority that prevents Santarus from performing its obligations under this Agreement, all together or in any material part, or otherwise makes such activity unlawful, or (ii) approval by FDA of an Abbreviated New Drug Application, or ANDA, submitted by a Third Party, for which the Product is the reference product and such approval is for an “AB” rated equivalent to the Product (a “Generic Product”).

     (d) Santarus may terminate this Agreement immediately in the event of a large scale recall or withdrawal of the Product from the market in the Territory resulting from a significant safety risk inherent in the Product and not due to (i) tampering, (ii) a remediable manufacturing problem, or (iii) other defect that can be cured with respect to Product manufactured after such risk is discovered.

     8.3 Termination for Cause

     Either S2 or VeroScience, on the one hand, or Santarus, on the other hand, may terminate this Agreement, effective at any time after providing at least sixty (60) days written notice and an

opportunity to cure during such sixty (60)-day period, in the event of a material failure of Santarus, on the one hand, or S2 or VeroScience, on the other hand, to comply with its material obligations contained in this Agreement. If such cure is effected within such sixty (60) day cure period, such notice with respect to such termination shall be null and void. Notwithstanding anything herein to the contrary, in the event that Santarus (a) gives notice of material breach of this Agreement by S2 pursuant to this Section 8.3, Santarus shall contemporaneously provide a copy of such notice to VeroScience, or (b) gives notice of material breach of this Agreement by VeroScience pursuant to this Section 8.3, Santarus shall contemporaneously provide a copy of such notice to S2. Santarus agrees that, in addition to the right of S2 and VeroScience to cure their own breach, S2 and VeroScience shall each have the right to cure any material breach by such other party. Additionally, either S2 or VeroScience may terminate this Agreement immediately if Santarus or any of its Affiliates directly or indirectly initiate or prosecute any lawsuit or any other civil or administrative proceeding, or the making of any claim or counterclaim, of any kind in any court, tribunal, agency or governmental entity anywhere in the world challenging the validity or enforceability of any VeroScience Patent. For the avoidance of doubt, the failure of S2 and VeroScience to comply with each of their obligations under Section 4.7, Section 7.4 and ARTICLE V of this Agreement shall be deemed a material breach of this Agreement.

     8.4 Termination for Bankruptcy or Force Majeure

     To the extent permitted by law, either S2 (on behalf of S2 and VeroScience) or Santarus (with respect to any event described in this Section 8.4 that is applicable to either S2 or VeroScience) may terminate this Agreement immediately upon notice to each other party, in the event of either of the following:

     (a) The entry of an order for relief under the United States Bankruptcy Code (or any corresponding remedy under successor laws) against another party; the filing of a petition by or against another party under any bankruptcy, insolvency or similar law (which petition is not dismissed within sixty (60) days after filing), except Chapter 11 of the United States Bankruptcy Code or any successor statute that permits a corporation to continue its operation while protecting it from creditors; the appointment of a receiver for another party’s business or property; or another party’s making of a general assignment for the benefit of its creditors; or

     (b) Any Force Majeure Event affecting another party beyond such other party’s control which lasts for a period of at least six (6) months and which is of sufficient intensity to interrupt or prevent the carrying out of such other party’s material obligations under this Agreement during such period.

     For clarity, neither S2 nor VeroScience may terminate this Agreement pursuant to this Section 8.4 with respect to any event described in this Section 8.4 that is applicable to either VeroScience or S2.

     8.5 Effect of Termination

     (a) No additional payment obligations arising under Article VII hereof shall accrue after the date of expiration or termination of this Agreement except as set forth in Section 7.1(f), 7.2 and Section 8.5(c)(iv); provided, however, that expiration or termination of this Agreement shall not relieve any party of any obligations accruing prior to such expiration or termination. Certain provisions of this Agreement by their terms continue after the expiration or termination of this Agreement, including Sections 2.4(a), 5.5, 5.6, 5.8, 7.1(f), 7.2, 7.3, 7.4, this Section 8.5, 14.1, Articles XI, XII, XIII and XV and solely with respect to the reports required for the Final Agreement Quarter or the final Agreement Month, as the case may be, Sections 4.6(b) and 4.6(c). In addition, any other provisions required to interpret and enforce the parties’ rights and obligations under this Agreement shall also survive, but only to the extent required for the full observation and performance of this Agreement.

     (b) Expiration or termination of this Agreement shall be without prejudice to (i) any remedies which any party may then or thereafter have hereunder or at law or in equity; and (ii) a party’s right to receive any payment accrued under the Agreement prior to the termination date but which became payable thereafter; and (iii) any party’s right to obtain performance of any obligations provided for in this Agreement which survive expiration or termination by their terms or by a fair interpretation of this Agreement. Except as expressly set forth herein, the rights to terminate as set forth herein shall be in addition to all other rights and remedies available under this Agreement, at law, or in equity or otherwise.

     (c) Upon the expiration or termination of this Agreement pursuant to this Article VIII:

               (i) All rights and licenses granted to Santarus by S2 and VeroScience under this Agreement shall terminate.

               (ii) Each party shall promptly transfer and return to the applicable party all Proprietary Information of such party (provided that each party may keep one copy of such Proprietary Information for the sole purpose of enforcing its rights under this Agreement).

               (iii) S2 may, but is not obligated to, purchase from Santarus, at Santarus’ cost (as determined pursuant to this Agreement) all remaining Samples and Promotional Materials; provided, however, that S2 shall be obligated to purchase such Samples from Santarus at cost in the event that this Agreement is terminated by Santarus pursuant to Sections 8.2(c)(i) or 8.3.

               (iv) Santarus shall have the right to sell its existing inventory of trade Product for a period of six (6) months following the effective date of termination subject to the payment obligations of Article VII. S2 may, but is not obligated to, purchase from Santarus, at

Santarus’ cost, all remaining trade Product; provided, however, that S2 shall be obligated to purchase such trade Product from Santarus at cost in the event that this Agreement is terminated by Santarus pursuant to Sections 8.2(c)(i) or 8.3.

               (v) Santarus shall take reasonable actions to transfer to S2 the contents and maintenance of the Websites.

               (vi) Santarus shall reasonably cooperate with S2 to facilitate orderly transition of Manufacturing and Commercialization of the Product, including by assigning or otherwise transferring (to the extent permissible) to S2 Santarus’ rights and obligations under Third Party contracts exclusively related to such Manufacturing or Commercialization (including the Patheon Agreement and the Supplemental Patheon Agreements), as reasonably requested by S2. Subject to the terms and conditions of this Agreement, Santarus shall remain responsible for all liabilities and obligations accrued, other than for Product delivered to S2 following the Term in accordance herewith, under such Third Party agreements prior to the effective date of such expiration or termination.

     VeroScience shall prosecute and maintain the intellectual property in the Territory related to the Product and necessary to Manufacture and Commercialize in the Territory pursuant to this Agreement, including the VeroScience Patents, the Listed Patents and the Product Trademarks. VeroScience shall make available to Santarus (or its designated counsel) copies of patent application files and shall make available to Santarus (or its designated counsel) all office actions relating to any patent applications wherein at least one (1) claim is directed to the Product in those patent applications, and copies of material correspondence with the U.S. Patent and Trademark Office relating to such patent applications to the extent they relate to the Product or its use. Santarus shall have the right to comment upon the prosecution of such patent applications. VeroScience shall, in good faith, consider such comments of Santarus. In addition, VeroScience shall keep Santarus reasonably informed regarding material developments relating to the prosecution, maintenance or enforcement of VeroScience’s intellectual property rights related to the Product outside the Territory that could reasonably be expected to have a material impact on VeroScience’s intellectual property rights related to the Product in the Territory. For the avoidance of doubt, VeroScience and S2 shall remain responsible for all expenses relating to the preparation, filing, prosecution and maintenance of the intellectual property in the Territory related to the Product and necessary to Manufacture and Commercialize in the Territory pursuant to this Agreement, including the VeroScience Patents, the Listed Patents, the Product Trademarks and any copyrights associated with the Promotional Materials. In the event that VeroScience notifies Santarus that it no longer wishes to prosecute or maintain the intellectual property in the Territory related to the Product and necessary to Manufacture and Commercialize in the Territory pursuant to this Agreement, VeroScience shall promptly notify Santarus in writing sufficiently in advance to any relevant deadline so that Santarus may, at its discretion, assume the responsibility for the prosecution or maintenance of such intellectual property in its own name and at its sole expense. In the event that Santarus also decides not to continue the prosecution or maintenance of such intellectual property, Santarus shall promptly notify S2 in writing sufficiently in advance to any relevant deadline so that S2 may, at its discretion, assume the responsibility for the prosecution or maintenance of such intellectual property in its own name and at its sole expense.

     10.2 Third Party Competition

     In recognition of Santarus’ agreement to exclusively Commercialize in the Territory, in accordance with the terms and conditions of this Agreement, and subject to Section 2.1(b), S2 and VeroScience each agree that if S2, VeroScience or any Affiliate thereof grants to any Affiliate or Third Party a license, covenant not to sue, right of reference, right of supply, other intellectual property right or other settlement related to the manufacture, use, offer for sale, sale, importation, marketing or promotion of the Product in the Territory, including any authorized generic version of the Product covered by the NDA in the Territory, but excluding the licenses under the S2/Vero Agreement as of the Effective Date, this Agreement and any license granted in connection with the manufacture of the Product in the Territory for Development or for Commercialization outside the Territory, then S2 or VeroScience, as applicable, shall obtain Santarus’ consent in advance of the grant of any such license, covenant not to sue, right of reference, right of supply, other intellectual property right or other settlement, and as part of such consent the parties shall negotiate in good faith financial adjustments to this Agreement adequate to compensate Santarus for any lost market share attributable to sales of the Product in the Territory by or on behalf of such Third Party or Affiliate, taking into account the consideration received by S2, VeroScience or any Affiliate thereof for the grant of such rights or other settlement.

     10.3 Enforcement or Defense of Patent Rights

     (a) If any party shall learn that any Third Party violates the intellectual property rights owned or Controlled by any party in the Product and/or the Product Trademarks in the Territory, or that a Third Party has initiated an action (or any counterclaim or defense asserted in any other action) in the Territory alleging invalidity or unenforceability of any VeroScience Patents, then the party becoming so informed shall promptly, but in all events within [***] ([***]) days thereof, notify the other parties to this Agreement of such information. In the event VeroScience receives a notice under Paragraph IV of the U.S. Federal Drug Price Competition and Patent Term Restoration Act of 1984, as amended, also known as the Hatch-Waxman Act, with respect to the Product, VeroScience shall provide Santarus and S2 with written notice of such Paragraph IV notice within [***] ([***]) business days (each, a “Paragraph IV Notice”).

     (b) If warranted in the opinion of Santarus, after consultation with S2 and VeroScience, Santarus shall take such legal action (“Enforcement Action”) as is advisable in Santarus’ reasonable opinion to restrain infringement of such patent rights related to the Product or the Product Trademarks, or to defend any Third Party action alleging invalidity or unenforceability in the Territory. S2 shall cooperate fully with, and as reasonably requested by, Santarus in any Enforcement Action, and Santarus shall reimburse S2 for its out-of-pocket expenses incurred in providing such cooperation. S2 may be represented by counsel of its own selection at its own expense in any Enforcement Action. If (i) Santarus elects in writing not to bring an Enforcement Action with respect to the Product in the Territory, (ii) within [***] ([***]) days following a written request by S2 or VeroScience to do so Santarus fails to bring an Enforcement Action (provided that in the case of a Paragraph IV Notice, Santarus shall confirm in writing its election to bring such Enforcement Action no later than [***] ([***]) days following receipt of the Paragraph IV Notice), or (iii) S2 otherwise fails to bring an Enforcement

Action or take other reasonable action to protect the patent rights related to the Product or the Product Trademarks in the Territory from such infringement, then, VeroScience shall have the first right, at its sole discretion, to institute an Enforcement Action in its own name using counsel of its choice, at its own expense, and with the right to control the course of such Enforcement Action (and Santarus and S2 shall provide all reasonable assistance, other than financial, to VeroScience for such Enforcement Action, at VeroScience’s expense, including joining such Enforcement Action if necessary to maintain the Enforcement Action, and Santarus and S2 shall have the right to join and participate in the Enforcement Action whether or not such joinder is requested by VeroScience). If VeroScience elects in writing not to exercise such right, or within [***] ([***]) days following a written request by S2 to do so VeroScience fails to bring or defend an Enforcement Action, then, in compliance with the in-license agreement with respect to applicable Product patent rights licensed from a Third Party, if any, S2 shall have the right, at its sole discretion, to institute an Enforcement Action in its own name using counsel of its choice, at its own expense, and with the right to control the course of such Enforcement Action (and VeroScience and Santarus shall provide all reasonable assistance, other than financial, to S2 for such Enforcement Action, at S2’s expense, including joining such Enforcement Action if necessary to maintain the Enforcement Action, and VeroScience and Santarus shall have the right to join and participate in the Enforcement Action whether or not such joinder is requested by S2); provided, however, that S2 shall obtain VeroScience’s and Santarus’ consent (not to be unreasonably withheld) in advance of the grant of any license, covenant not to sue, right of reference, right of supply, other intellectual property right or other settlement in any Enforcement Action. In each Enforcement Action, each party shall have the right to fund a portion of the Enforcement Action. Any recovery received as a result of any Enforcement Action shall be used first to reimburse the parties for their out-of-pocket costs and expenses (including attorneys’ and professional fees) incurred in connection with such Enforcement Action (and not previously reimbursed). If such recovery is insufficient to cover all such costs and expenses of each party, it shall be shared in proportion to the total of such costs and expenses incurred by each party. Any amounts remaining thereafter, to the extent relating to the Product in the Territory or an Included Additional Product in the Territory, shall be shared by the parties [***]. For clarity, S2 and VeroScience shall be responsible to make any payments required to Third Party Rights Holders out of their share; provided, that neither S2 nor VeroScience shall be obligated to pay Third Party Rights Holders more than the amounts such parties receive in connection with such Enforcement Action.

     10.4 Infringement Claims

     (a) If any party shall learn of a claim or assertion that the manufacture, use or sale of the Product in the Territory infringes or otherwise violates the intellectual property rights of any Third Party, then the party becoming so informed shall promptly, but in all events within [***] ([***]) days thereof, notify the other parties to this Agreement of the claim or assertion.

     (b) If warranted in the opinion of Santarus, after consultation with S2 and VeroScience, Santarus shall take such legal action as is advisable in Santarus’ reasonable opinion to defend such infringement claims in the Territory. S2 shall cooperate fully with, and as reasonably requested by, Santarus in any such defense, and Santarus shall reimburse S2 for its

out-of-pocket expenses incurred in providing such cooperation. S2 may be represented by counsel of its own selection at its own expense in any Enforcement Action. If (i) Santarus elects in writing not to defend any infringement claim with respect to the Product in the Territory, (ii) within [***] ([***]) days following a written request by S2 or VeroScience to do so Santarus fails to defend such a claim, or (iii) Santarus otherwise fails to defend an infringement claim or take other reasonable action to protect the parties’ rights related to the Product, or to abate such infringement, then, VeroScience shall have the first right, at its sole discretion, to defend such infringement claim in its own name using counsel of its choice, at its own expense, and with the right to control the course of such defense (and Santarus and S2 shall provide all reasonable assistance, other than financial, to VeroScience for such defense, at VeroScience’s expense, and Santarus and S2 shall have the right to join and participate in the defense of such infringement claim whether or not such joinder is requested by VeroScience). If VeroScience elects in writing not to exercise such right, or within [***] ([***]) days following a written request by S2 to do so VeroScience fails to defend an infringement claim, then, in compliance with the in-license agreement with respect to applicable Product patent rights licensed from a Third Party, if any, S2 shall have the right, at its sole discretion, to defend an infringement claim in its own name using counsel of its choice, at its own expense, and with the right to control the course of such defense (and VeroScience and Santarus shall provide all reasonable assistance, other than financial, to S2 for such defense, at S2’s expense, and VeroScience and Santarus shall have the right to join and participate in the defense of such infringement claim whether or not such joinder is requested by S2); provided, however, that S2 shall obtain VeroScience’s and Santarus’ consent (not to be unreasonably withheld) in advance of the grant of any license, covenant not to sue, right of reference, right of supply, other intellectual property right or other settlement in any such infringement claim defense. In each infringement claim defense, each party shall have the right to fund a portion of the defense. Any recovery received as a result of any defense shall be used first to reimburse the parties for their out-of-pocket costs and expenses (including attorneys’ and professional fees) incurred in connection with such defense (and not previously reimbursed). If such recovery is insufficient to cover all such costs and expenses of each party, it shall be shared in proportion to the total of such costs and expenses incurred by each party. Any amounts remaining thereafter, to the extent relating to the Product in the Territory or an Included Additional Product in the Territory, shall be shared by the parties [***]. For clarity, S2 and VeroScience shall be responsible to make any payments required to Third Party Rights Holders out of their share; provided, that neither S2 nor VeroScience shall be obligated to pay Third Party Rights Holders more than the amounts such parties receive in connection with such Enforcement Action.

VeroScience and its Affiliates shall have the right to make disclosures pertaining to the Product and any Included Additional Product, subject to the prior review and comment by Santarus and S2 as follows: VeroScience shall provide a copy of any such proposed abstract, manuscript, or presentation, to the extent relating directly to the Product or an Included Additional Product, to Santarus and S2 no less than [***] ([***]) calendar days prior to VeroScience’s intended submission for publication. Santarus and S2 shall respond in writing promptly and in no event later than [***] ([***]) calendar days after receipt of the proposed material, with one or both of the following: (a) comments on the proposed material, or (b) an identification of Santarus’ or S2’s Proprietary Information, as applicable, that is contained in the material reviewed.

In the case of conference abstracts and other rapid scientific communications, the parties will use reasonable efforts to complete the review process in [***] ([***]) business days or less. To the extent that Santarus has a proposed publication, Santarus shall provide S2 and VeroScience with the timely opportunity to review and comment on such proposed publication, subject to the process as set forth above but applicable to Santarus instead of VeroScience. Santarus’s right to publish under this Section 12.4 shall be limited to information directly related to the Product, and shall at all times be subject to VeroScience’s first right to publish any such information and to the confidentiality obligations hereof.

ARTICLE XV
MISCELLANEOUS

     15.1 Headings

     The titles, headings or captions and paragraphs in this Agreement are for convenience only and do not define, limit, extend, explain or describe the scope or extent of this Agreement or any of its terms or conditions and therefore shall not be considered in the interpretation, construction or application of this Agreement.

     15.2 Severability

     In the event that any of the provisions or a portion of any provision of this Agreement is held to be invalid, illegal, or unenforceable by a Governmental Authority, such provision or portion of provision will be construed and enforced as if it had been narrowly drawn so as not to be invalid, illegal, or unenforceable, and the validity, legality, and enforceability of the enforceable portion of any such provision and the remaining provisions will not be adversely affected thereby.

     15.3 Entire Agreement

     This Agreement, together with the schedules and exhibits hereto, all of which are incorporated by reference, contains all of the terms agreed to by the parties regarding the subject matter hereof and supersedes any prior agreements, understandings, or arrangements between them, whether oral or in writing. No party shall enter into any agreement that modifies the terms of this Agreement without the prior written consent of each of the other parties, including any amendment to or waiver under the S2/Vero Agreement (except as permitted under Section 6.6).

     15.4 Amendments

     This Agreement may not be amended, modified, altered, or supplemented except by means of a written agreement or other instrument executed by each of the parties hereto. No course of conduct or dealing between the parties will act as a modification or waiver of any provisions of this Agreement.

     15.5 Counterparts

     This Agreement may be executed in any number of counterparts (including by facsimile or electronic signature), each of which will be deemed an original as against the party whose signature appears thereon, but all of which taken together will constitute but one and the same instrument.

     15.6 Waiver

     The failure of any party to enforce or to exercise, at any time or for any period of time, any term of or any right arising pursuant to this Agreement does not constitute, and will not be construed as, a waiver of such term or right, and will in no way affect that party’s right later to enforce or exercise such term or right.

     15.7 Force Majeure

     (a) In the event of any failure or delay in the performance by a party of any provision of this Agreement due to acts beyond the reasonable control of such party (such as, for example, fire, explosion, strike or other difficulty with workmen, shortage of transportation equipment, accident, act of God, declared or undeclared wars, acts of terrorism, or compliance with or other action taken to carry out the intent or purpose of any law or regulation, but not any failure of

such party to perform under a Third Party agreement) (a “Force Majeure Event”), then such party shall have such additional time to perform as shall be reasonably necessary under the circumstances. In the event of such failure or delay, the affected party will use its diligent efforts, consistent with sound business judgment and to the extent permitted by law, to correct such failure or delay as expeditiously as possible. In the event that a party is unable to perform by a reason described in this Section 15.7, its obligation to perform under the affected provision of this Agreement shall be suspended during such time of nonperformance.

     (b) No party shall be liable hereunder to another party nor shall be in breach for failure to perform its obligations caused by a Force Majeure Event. In the case of any such event, the affected party shall promptly, but in no event later than [***] ([***]) days of its occurrence, notify the other parties stating the nature of the condition, its anticipated duration and any action being taken to avoid or minimize its effect. Furthermore, the affected party shall keep the other parties reasonably informed of the efforts to resume performance. After [***] ([***]) days of such inability to perform, the parties agree to meet and in good faith discuss how to proceed. In the event that the affected party is prevented from performing its obligations pursuant to this Section 15.7 for a period of [***] ([***]) months, the other parties shall have the right to terminate this Agreement pursuant to the provisions of Section 8.4(b).

     (c) Under no circumstances shall a Supply Failure be considered a Force Majeure Event unless and only to the extent such Supply Failure is attributable to a Force Majeure Event.

     15.8 Successors and Assigns

     Subject to Section 15.9, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns permitted under this Agreement.

     15.9 Assignment

     This Agreement and the rights granted herein shall not be assignable (or otherwise transferred) by any party hereto without the prior written consent of the other parties. Any attempted assignment without consent shall be void. Notwithstanding the foregoing, a party may transfer, assign or delegate its rights and obligations under this Agreement without consent to (a) an Affiliate reasonably capable of performing such party’s obligations under this Agreement or (b) a successor to all or substantially all of its business or assets of the assigning party to which this Agreement relates, whether by sale, merger, consolidation, acquisition, transfer, operation of law or otherwise or (c) in the case of Santarus, to one or more Persons providing financing to such party pursuant to the terms of a security agreement relating to such financing. Notwithstanding anything contained herein to the contrary, each of VeroScience and Santarus shall have the right to engage Third Party subcontractors (including academic collaborators) to perform services in connection with the performance by such party of its obligations hereunder, without the consent of S2 or the other party, and may assign or sublicense to such Third Parties such rights hereunder as are reasonably necessary for the performance of such services by such Third Parties; provided, with respect to each such subcontract, that (a) the contracting party shall

ensure that each of its subcontractors accepts and complies with all applicable terms and conditions of this Agreement, (b) the contracting party shall remain responsible for the performance of its subcontractors hereunder, and (c) any such subcontract shall (i) be subject and subordinate to the terms and conditions of this Agreement, (ii) contain terms and conditions which are consistent with the terms and conditions of this Agreement, and (iii) not in any way diminish, reduce or eliminate any of the contracting party’s obligations under this Agreement.

     15.10 Construction

     The parties acknowledge and agree that: (a) each party and its representatives have reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; and (b) the terms and provisions of this Agreement will be construed fairly as to each party hereto and not in favor of or against any party regardless of which party was generally responsible for the preparation or drafting of this Agreement. Unless the context of this Agreement otherwise requires: (i) words of any gender include each other gender; (ii) words using the singular or plural number also include the plural or singular number, respectively; (iii) the terms “hereof,” “herein,” “hereby,” and derivative or similar words refer to this entire Agreement; (iv) the terms “Article,” “Section,” “Exhibit,” “Schedule,” or “clause” refer to the specified Article, Section, Exhibit, Schedule, or clause of this Agreement; (v) “or” is disjunctive but not necessarily exclusive; and (vi) the term “including” or “includes” means “including without limitation” or “includes without limitation.” Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless business days are specified.

     15.11 Governing Law

     This Agreement will be construed under and in accordance with, and governed in all respects by, the laws of the State of New York, without regard to its conflicts of law principles.

     15.12 Decision-Making; Dispute Resolution

     The parties recognize that a bona fide dispute as to certain matters may from time to time arise during the Term that relate to a party’s rights or obligations hereunder, including a dispute arising out of or relating to the interpretation of any provisions of this Agreement or the failure of a party to perform or comply with any obligation of such party pursuant to this Agreement or the breach, termination or validity hereof (a “Dispute”). Unless otherwise set forth in this Agreement, in the event of a Dispute arising under this Agreement among the parties, any party may refer such Dispute to the Executive Officers for a decision. The Executive Officers shall diligently and in good faith attempt to resolve the referred Dispute expeditiously and, in any event, within [***] ([***]) days of receiving such written notification. In the event that the Executive Officers are unable to reach a unanimous decision regarding any referred Dispute within the [***] ([***])-day period, then such Dispute shall be finally settled by binding arbitration, such arbitration to be conducted in accordance with the provisions set forth in Schedule 15.12. Each party shall participate in any such arbitration proceeding unless otherwise agreed by each Executive Officer. Except as otherwise set forth in this Agreement, the procedures specified in Schedule 15.12 shall be the sole and exclusive procedures for the

resolution of disputes between the parties arising out of or relating to this Agreement; provided, that a party, without prejudice to such procedures, may seek injunctive relief or other provisional judicial relief if in its sole judgment such action is necessary to avoid irreparable damage. Despite such action, the parties will continue to participate in good faith in the procedures specified in Schedule 15.12. Each party is required to continue to perform its obligations under this Agreement pending final resolution of any such Dispute.

     15.13 Equitable Relief

     Each party acknowledges that a breach by it of the provisions of this Agreement may not reasonably or adequately be compensated in damages in an action at law and that such a breach may cause the other party(ies) irreparable injury and damage. By reason thereof, each party agrees that the other parties are entitled to seek, in addition to any other remedies they may have under this Agreement or otherwise, preliminary and permanent injunctive and other equitable relief to prevent or curtail any breach of this Agreement by another party; provided, however, that no specification in this Agreement of a specific legal or equitable remedy will be construed as a waiver or prohibition against the pursuing of other legal or equitable remedies in the event of such a breach. Each party agrees that the existence of any claim, demand, or cause of action of it against another party predicated upon this Agreement will not constitute a defense to the enforcement by another party, or its successors or assigns, of the covenants contained in this Agreement.

     15.14 Relationship Between Parties

     The parties hereto are acting and performing as independent contractors, and nothing in this Agreement creates the relationship of partnership, joint venture, sales agency, or principal and agent. No party is the agent of another party hereunder, and no party may hold itself out as such to any other Person. Except as specifically provided herein, all financial obligations associated with each party’s business will be the sole responsibility of such party.
