2. Development and Regulatory Approval.

2.1 Development. Argent represents to Vertical (and this information can and should be verified by Vertical with Mikart) that the development for the Products has been sufficiently completed to enable Mikart to file the ANDA with the FDA.

Vertical acknowledges that there can be no guarantee that the FDA will not require Mikart to conduct additional development work before it issues its Approval, and no commitment should be made by Vertical to any third party that is inconsistent with this acknowledgment.

2.2 Regulatory Approval. Argent and Vertical acknowledge and agree that: (a) the Contract Manufacturer shall be the holder of the ANDA for the Products; (b) the Contract Manufacturer has filed the ANDA for the Products with the FDA; (c) the Contract Manufacturer and Argent are responsible for the Approval of the Products in the United States; and (d) the Contract Manufacturer shall maintain the approved ANDA in full compliance with all relevant provisions of the Act. The regulatory responsibilities of the Contract Manufacturer, as it relates to the Products, will be more fully delineated in the Supply Agreement (as that term is defined in Section 4 below) that will be executed by Vertical and the Contract Manufacturer for the Products. Vertical acknowledges there are risks inherent in the regulatory processes for the Products and that there can be no guarantee that the Contract Manufacturer will be able to obtain or maintain the Approval, and no commitment should be made by Vertical to any third party that is inconsistent with this acknowledgment.

2.3 Reporting. Argent shall immediately notify Vertical in writing if it receives any information in writing from the Contract Manufacturer specifically naming the Products that the Approval, when obtained for the Products, may be thereafter withdrawn by the FDA.

3. Distribution of Product.

3.1 Grant. Subject to the terms and conditions set forth in this Agreement, Argent hereby grants to Vertical an exclusive and perpetual marketing right under Mikart’s Approval to offer for sale, sell, market, promote, distribute, and otherwise transfer, dispose, provide, and place (“sell”) the Products in the Territory. Vertical shall have the right, in its sole discretion, to distribute the Products directly or through one or more sub-distributors. It is expressly understood by Vertical that the marketing rights granted under this Section 3.1 by Argent to Vertical do not give Vertical the right to grant additional marketing rights nor enter into any co-promotion or co-marketing agreements for the Products with any non-Affiliated third party, unless the parties hereto agree otherwise in writing. Moreover, Vertical’s marketing rights do not give Vertical the right to transfer its marketing rights to any non-Affiliated third party without the prior written consent of Argent as set forth in Section 12.7 below. The word “perpetual” as used above in this Section 3.1 and in Sections 8.3.1 and 11.1 below is subject to the understanding that the initial term of the Product Development Agreement between Mikart and Argent is fifteen (15) years from its effective date of June 7, 2005 and that such Product Development Agreement is stated to be automatically renewed for five (5)-year renewal terms unless terminated upon at least two (2) years written notice from one party to the other, and that for so long

as such Product Development Agreement remains in full force and effect with respect to the Product, Vertical’s marketing rights hereunder, unless terminated pursuant to Section 11 below, will be “perpetual”.

3.2 Performance Criteria. Vertical shall be responsible, at its sole cost and expense, for all manufacturing of the Products, pursuant to the provisions of Section 4 ‘ hereof, any costs related to additional process-validation activities, if any, the annual stability study activities related to the Products after the FDA has approved the AND A, regulatory matters related to the commercial sale of the Products, and all promotion and distribution related to the commercialization of the Products in the Territory. Upon the Launch of the Products by Vertical, and continuing for a period of [***] following Launch, Vertical shall, in good faith and without undue delay, have a minimum of at least [***] sales representatives assigned to actively detail the Products in accordance with the First Position Commitment, as defined in Section 1.8 hereof. Commencing with the [***] following the Launch of the Products, Vertical shall have a minimum of [***] sales representatives assigned to actively detail the Products in accordance with the First Position Commitment and shall maintain at least that number of sales representatives throughout the Term (as that term is defined in Section 11.1 below) hereof (except as set forth below) (the “Minimum Promotion Commitment”). Vertical’s Launch shall comprise efforts no less rigorous than those efforts that Vertical customarily expends to commercialize its other products similar to the Products. Vertical shall Launch the Products as soon as possible following the Approval Date of the ANDA pertaining to the Products, but in no case later than sixty (60) days after such Approval Date, subject to its ability to obtain sufficient quantities of the Product(s) from the Contract Manufacturer to allow a Launch subject to the terms of this Section 3.2. The Minimum Promotion Commitment (including the First Position Commitment for the First Position Commitment Period) shall be maintained until the commercial sale of a Generic Equivalent Product in the Territory by a non-Affiliated third party. For the avoidance of doubt, a “Generic Equivalent Product” is defined to be a product that must be approved by the FDA pursuant to the FDA’s ANDA process and that must carry a generic equivalency rating of “AA” to the Products. If a Generic Equivalent Product is sold commercially in the Territory and then subsequently withdrawn, with no other Generic Equivalent Product being sold commercially in the Territory, then Vertical will, in good faith and without undue delay, once again comply with the foregoing Minimum Promotion Commitment as soon as is it practical to do so. If the First Position Commitment is interrupted for any reason permitted hereunder (e.g., a Product supply interruption as set forth in Section 4.2 below or an event of Force Majeure as set forth in Section 12.11 below) before Vertical has complied therewith in full for the entire First Position Commitment Period, then that obligation shall be reinstated as soon as possible after such interruption until Vertical has complied in full with such obligation for an aggregate of the [***] of the First Position Commitment Period.

3.3 Generic Versions of the Products by Vertical. Argent understands that Vertical, or Vertical’s Affiliate, Trigen Laboratories, Inc., may wish to market its own generic versions of the Products, which initially will be marketed by Vertical solely as branded versions. Vertical agrees to do so only when Vertical believes in good faith, based upon credible market information, that a Generic Equivalent Product is on, or is expected to shortly come into, the market in the Territory. At such time, Argent understands that Vertical could have both branded and generic sales of the Products in the Territory.

4. Product Manufacturing.

4.1 Supply Agreement. The Product Development Agreement requires that, as a condition of entering into a marketing agreement with any marketing company, Argent require the marketing company to enter into an exclusive manufacturing agreement with the Contract Manufacturer, once again, in this case, Mikart. Accordingly, Argent hereby acknowledges and agrees that Vertical’s duties and obligations hereunder are dependent upon Vertical’s ability to obtain and maintain an adequate supply of the Products from the Contract Manufacturer. Accordingly, Argent shall cooperate with Vertical to ensure that a long-term supply agreement is executed between Vertical and the Contract Manufacturer with respect to the Products (“Supply Agreement”), provided, however, that the Products shall only be delivered to Vertical or its Customers (or Vertical’s sub-distributors) and not to or on behalf of Argent. The terms and conditions governing Vertical’s responsibilities related to the supply of the Products to Vertical by the Contract Manufacturer shall be more fully delineated in the Supply Agreement between Vertical and the Contract Manufacturer. Argent shall not be obligated to enter into this Agreement until both Vertical and Mikart have notified Argent in writing that they are each prepared to, and will, enter into the Supply Agreement at the same time that Argent and Vertical will be entering into this Agreement.

4.2 Transfer of Supply Agreement. Argent and Mikart have agreed in the Product Development Agreement that, should Mikart be unable or unwilling to continue to fulfill its obligations to manufacture and supply the Products, Mikart will cooperate with Argent and/or Argent’s transferee(s) to effect an orderly transfer of the manufacturing for the Products to an alternate third-party contract manufacturer mutually acceptable to the parties. Any such transfer will be undertaken in a manner that attempts to minimize the potential for supply disruption for the Products, and the Supply Agreement between Mikart and Vertical shall state specifically that all costs incurred in such transfer shall be paid by Mikart and Vertical shall not be responsible for same (nor shall Argent). As all of the manufacturing information pertaining to the Products has been developed by Mikart and has been incorporated in (or will be incorporated in) its regulatory filings, such information is considered under the confidentiality provisions of the Product Development Agreement to be the confidential information of Mikart. However, as set forth in Section 8.3.4 below, in the event that supply of the Products from the Contract Manufacturer ceases or is disrupted for more than

ninety (90) days or in a manner that significantly affects Vertical’s sales of the Products, then Vertical’s obligations under this Agreement (other than the submission of royalty reports and payments under Section 8.4 below) shall be suspended until there is a resumption of supply (or sufficient supply) by the Contract Manufacturer or there is a transfer of the manufacturing duties for the Products to an alternate third-party contract manufacturer mutually acceptable to the parties, and Vertical’s other obligations under this Agreement shall be extended for a period of time equal to any period of suspension. For the avoidance of doubt, a condition precedent to Mikart’s obligation to transfer the manufacturing for the Products to an alternate third-party contract manufacturer mutually acceptable to the parties shall be the existence of a Supply Agreement for the Products between Vertical and Mikart in which Vertical is not in material breach of the provisions thereof.

5. Marketing and Support Activities.

5.1 Marketing Meetings; Reports. Following the Launch of the Products by Vertical, representatives of Argent and Vertical shall meet at least quarterly to discuss Vertical’s marketing plans and other information concerning the ongoing commercialization of the Products. Vertical shall provide information available to it about the Products and its ability to compete with other products for related uses and to meet customer needs. Vertical shall provide Argent information regarding sales of the Products, including but not limited to such information as pricing trends on a national basis.

5.2 Packaging, Tooling and Labeling. Vertical, at Vertical’s sole expense, and in conjunction with the Contract Manufacturer, shall develop all packaging, tooling, labeling, and package inserts for the Products. All such packaging, tooling, labeling, and package inserts shall comply with applicable FDA requirements.

5.3 Trademarks. Vertical agrees to file all applications necessary to register its brand name(s) for the Products for trademark protection (the “Trademarks(s)”) with the United States Patent and Trademark Office not later than sixty (60) days prior to the date of first commercial sale by Vertical of the Products in the Territory. Vertical shall be the sole and exclusive owner of all right, title and interest in and to such Trademark(s) for the Product. Vertical further agrees, at its sole expense, to prosecute and/or defend any claim of infringement that may arise as a result of the use of the Trademark(s) in accordance with this Agreement and to hold Argent harmless with respect thereto. In accordance with the provisions of Section 11 of this Agreement, as they relate to the Trademark(s) used by Vertical for the Products, Vertical agrees to promptly execute any documents that Argent asserts are needed to transfer all rights in the Trademark(s) to Argent in consideration of Argent’s agreement to pay the Trademark Royalty (as that term is defined in Section 11.5 below) for such Trademark(s).

6. Compliance. Vertical shall maintain, or cause to be maintained, all complaint files and other records required to be maintained by the FDA and other regulatory agencies with respect to the Products supplied to Vertical by the Contract Manufacturer. Vertical and the Contract Manufacturer shall be responsible for compliance with all necessary regulatory reporting requirements for the Products. Specific reporting obligations of Vertical and the Contract Manufacturer shall be more fully delineated in the Supply Agreement.

7. Product Warranty and Limitation of Liability.

7.1 No Warranty. ARGENT GRANTS NO WARRANTIES FOR THE PRODUCTS, EXPRESS OR IMPLIED, EITHER IN FACT OR BY OPERATION OF LAW, BY STATUTE OR OTHERWISE, AND ARGENT SPECIFICALLY DISCLAIMS ANY IMPLIED WARRANTY OF QUALITY, WARRANTY OF MERCHANTABILITY, WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE OR WARRANTY OF NON-INFRINGEMENT.

7.2 Limitation of Liability. EXCEPT AS PROVIDED FOR IN SECTION 10.3 BELOW, IN NO EVENT SHALL ARGENT BE LIABLE TO VERTICAL FOR ANY SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES (INCLUDING BUT NOT LIMITED TO LOSS OF PROFITS) ARISING OUT OF ANY PERFORMANCE OF THIS AGREEMENT OR IN FURTHERANCE OF THE PROVISIONS OR OBJECTIVES OF THIS AGREEMENT, REGARDLESS OF WHETHER SUCH DAMAGES ARE BASED ON TORT, WARRANTY, CONTRACT OR ANY OTHER LEGAL THEORY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE AGGREGATE LIABILITY OF ARGENT FOR DAMAGES UNDER THIS AGREEMENT, REGARDLESS OF THE FORM OF THE ACTION AND/OR THE LEGAL THEORY ALLEGED, SHALL BE LIMITED TO [***].

8. Consideration for Grant of Marketing Rights.

8.1 Fixed Payments. As consideration for the marketing rights granted to Vertical hereunder, Vertical shall pay to Argent certain fixed payments as follows.

8.1.1 a signing payment of Three Hundred Thousand Dollars ($300,000) due on the Effective Date; and

8.1.2 the sum of Nine Hundred Thousand Dollars ($900,000) to be paid in fifteen (15) equal monthly payments of Sixty Thousand Dollars ($60,000) each month commencing on the first day of the first month following the Approval Date for the Products.

8.2 Prompt Ordering of Product. Vertical shall, not later than ten (10) business days after the Approval Date, submit binding purchase orders to the Contract Manufacturer for such quantities of the Products as are needed to commercialize the Products in the Territory. However, Vertical shall, at a minimum, submit binding purchase orders to the Contract Manufacturer in quantities sufficient to

cover the required three (3) commercial validation batches for each of the Products.

8.3 Royalties.

8.3.1 Subject to Sections 8.3.2 and 8.4, below, as additional consideration for the marketing rights granted hereunder, Vertical shall pay to Argent a perpetual royalty payment equal to [***] of annual Net Sales of the Products, whether brand or generic, for the first [***] in annual Net Sales and [***] of annual Net Sales in excess of [***] (the “Actual Royalty Payment”).

8.3.2 Subject to Section 8.3.3 below, in the event that the Actual Royalty Payment does not equal [***] (the “Minimum Annual Royalty”) for each twelve (12) month period beginning with the first day of the sixteenth (16th) month following the Approval Date, Vertical shall pay to Argent, in addition to the Actual Royalty Payments made during each such period, the difference between [***] and the aggregate Actual Royalty Payments paid for each such twelve (12) month period (each such payment made pursuant to this Section 8.3.2 shall be referred to as a “Supplemental Royalty Payment”).

8.3.3 (a) The Minimum Annual Royalty outlined in Section 8.3.2 above shall be reduced to [***] for the Products beginning with the Is day of the calendar month immediately following the commercial sale of one or more Generic Equivalent Products in the Territory (as such products are defined in Section 3.2 above). The Minimum Annual Royalty shall be prorated for the then-current twelve (12) month period consistent with the reduction thereof as set forth in this Section 8.3.3(a). (b) If one or more Generic Equivalent Products launched in the Territory are subsequently withdrawn with no other Generic Equivalent Products remaining on the market in the Territory, the Minimum Annual Royalty will increase to [***] for the Products beginning with the 1st day of the calendar month immediately following the withdrawal from commercial sale of the last of the Generic Equivalent Products in the Territory and the Minimum Annual Royalty shall be prorated for the then- current twelve (12) month period consistent with the increase thereof as set forth in this Section 8.3.3(b).

8.3.4 In the event that supply of the Products from the Contract Manufacturer ceases or is disrupted for more than one hundred twenty (120) days or in a manner that significantly affects Vertical’s sales of the Products, through no fault of Vertical (whether by act or omission), then Vertical’s obligations under this Agreement shall be suspended (other than the submission of royalty reports and payments under Section 8.4 below) until there is a resumption of supply (or sufficient supply) by the Contract

Manufacturer or there is a transfer of the manufacturing duties for the Products to an alternate third-party contract manufacturer mutually acceptable to the parties, and Vertical’s other obligations under this Section 8.3 shall be extended for a period of time equal to any period of such suspension.

8.4 Royalty Reports and Payments Due. The royalty payments described in Section 8.3 hereof shall be paid by Vertical to Argent on a calendar quarter basis as follows:

8.4.1 Vertical shall pay each Actual Royalty Payment not later than forty-five (45) days following the close of each calendar quarter during the Term hereof. For the avoidance of doubt, the first Actual Royalty Payment for the Products will be due and payable not later than forty-five (45) days following the close of the calendar quarter during which the date of first commercial sale for any of the Products to a Customer occurs in the Territory. The first royalty report shall include all Products sold up to, and including, the last day of the calendar quarter for which the royalty report is being given. Each royalty report shall include all written documentation supporting Vertical’s determination of Net Sales upon which the royalty of Section 8.3.1 above has been calculated.

8.4.2 In the event that Vertical is obligated to pay Argent a Supplemental Royalty Payment hereunder, then Vertical shall pay the required Supplemental Royalty Payment not later than forty-five (45) days following the close of the twelve (12) month period for which a Minimum Annual Royalty is applicable and owed to Argent hereunder.

8.5 Acquisition Payment. In the event that Vertical is acquired or merged into anew, non-Affiliated company (for the purposes hereof, such company is hereby arbitrarily named “NEWCO”) within the First Position Commitment Period, NEWCO (and/or Vertical if Vertical remains as a operating entity) shall be responsible for carrying out all of the responsibilities of Vertical as set forth herein, however, NEWCO shall have the option to either (a) adhere to the First Position Commitment requirements as specified herein or (b) opt out of the First Position Commitment by making a one-time payment to Argent according to the schedule outlined in Sections 8.5.1, 8.5.2 or 8.5.3 below, all subject to Section 8.5.4 below.

8.5.1 If NEWCO elects to exercise the option outlined in Section 8.5(b) above within the first twelve months of the First Position Commitment Period, NEWCO shall make a one-time payment to Argent in the amount of Seven Hundred Fifty Thousand Dollars ($750,000). The exercise of the option in Section 8.5(b), and the payment of the consideration outlined in this Section 8.5.1, shall only relieve NEWCO of the requirements under the First Position Commitment. All

other requirements set forth in this Agreement, including, without limitation, the Minimum Promotion Commitment, remain unchanged.

8.5.2 If NEWCO elects to exercise the option outlined in Section 8.5(b) above within months thirteen (13) to twenty four (24) of the First Position Commitment Period, NEWCO shall make a one-time payment to Argent in the amount of Seven Hundred Fifty Thousand Dollars ($750,000). The exercise of the option in Section 8.5(b), and the payment of the consideration outlined in this Section 8.5.2, shall only relieve NEWCO of the requirements under the First Position Commitment. All other requirements set forth in this Agreement, including, without limitation, the Minimum Promotion Commitment, remain unchanged.

8.5.3 If NEWCO elects to exercise the option outlined in Section 8.5(b) above within months twenty-five (25) to thirty-six (36) of the First Position Commitment Period, NEWCO shall make a one-time payment to Argent in the amount of Five Hundred Thousand Dollars ($500,000). The exercise of the option in Section 8.5(b), and the payment of the consideration outlined in this Section 8.5.3, shall only relieve NEWCO of the requirements under the First Position Commitment. All other requirements set forth in this Agreement, including, without limitation, the Minimum Promotion Commitment, remain unchanged.

8.5.4 If the First Position Commitment is interrupted for any reason permitted hereunder (e.g., a Product supply interruption as set forth in Section 4.2 below or an event of Force Majeure as set forth in Section 12.11 below) before Vertical has complied therewith in full for the entire First Position Commitment Period, then that obligation as set forth in Section 3.2 above shall be reinstated as soon as possible after such interruption until Vertical has complied in full with such obligation for an aggregate of the thirty-six (36) months of the First Position Commitment Period and the twelve (12) months periods thereof as set forth in Sections 8.5.1, 8.5.2 and 8.5.3 above shall be determined not with respect to the initial start date of the First Position Commitment Period, but with respect to the reinstated dates as may be applicable with respect thereto.

8.6 Sales Activity Reporting. After the date of first commercial sale for the Products by Vertical, Vertical shall make quarterly written reports to Argent within forty- five (45) days after the first day of each January, April, July, and October during the Term hereof and, as of such dates, stating in each such report a) the number, description, and aggregate sales of the Products sold during the preceding three (3) calendar months and upon which amounts are payable as provided in Sections 8.3 and 8.4 above, b) the number of Vertical sales representatives actively assigned to detail the Products to target physicians at the end of the quarterly period, c) the total number of first position details for the Products given to target physicians by Vertical sales representatives during the quarter and d) the total number of details for the Products given to target physicians by Vertical sales

representatives during the quarter. The first such report shall include all Products sold and all sales representatives’ activity up to, and including, the last day of the calendar quarter for which the sales report is being given.

8.7 Accounting and Records. Vertical shall keep complete, true and accurate books of account and records for the purpose of showing the derivation of all amounts payable to Argent under this Agreement. Such books and records shall be kept at Vertical’s principal place of business for at least three (3) years following the end of the calendar quarter to which they pertain, and shall be available for inspection by a representative of Argent, not more than once per calendar year during the Term hereof and during normal business hours of Vertical, for the sole purpose of verifying Vertical’s royalty statements. The representatives of Argent shall be obliged to treat all such books and records as Proprietary Information of Vertical, except as required by law. Any such inspections shall be at the sole expense of Argent, unless a variation or error in excess of [***] of the royalties actually paid is discovered in the course of any such inspection, whereupon all costs relating thereto shall be paid by Vertical, subject to the verification procedure described herein. Vertical shall pay to Argent within thirty (30) days of receiving notice from Argent the full amount of any underpayment, together with interest thereon at the lower of the rate of [***] per month or the maximum rate permitted under applicable law. If Vertical disagrees with the determination by Argent that an underpayment has been made by Vertical, Vertical shall within ten (10) days after receipt of the notice from Argent of the underpayment so inform Argent and the matter shall promptly and in good faith be referred by both parties to a mutually acceptable certified public accountant for an independent verification of which party’s view is correct, which referral shall take place no later than twenty (20) days after the date of Vertical’s notification to Argent that Vertical believes that Argent’s determination is in error. The compensation for such certified public accountant shall be paid by the party whose view is not verified or upheld by the certified public accountant.

8.8 Interest. Any payment required under this Section 8 that is not received by Argent on the date due shall accrue interest at a rate of [***] per month, or the maximum rate allowed by law, whichever is less.

9. Confidentiality.

9.1 Non-Disclosure. During the Term hereof and for [***] thereafter, neither party shall disclose to third parties, or use for its benefit or the benefit of any third party, in whole or in part, any Proprietary Information received from the other party, except to the extent required to perform its obligations under this Agreement or comply with the Act or other laws. Each party shall take all reasonable steps to minimize the risk of disclosure of Proprietary Information, including, without limitation:

(a) ensuring that only its employees, agents and consultants whose duties require them to possess such Proprietary Information have access thereto;

(b) ensuring that such employees, agents and consultants are contractually bound to maintain the confidentiality of such Proprietary Information on terms no less stringent than those of this Agreement; and

(c) exercising at least the same degree of care with respect to Proprietary Information received from another party that it uses for its own Proprietary Information, which degree of care shall be no less than reasonable.

Notwithstanding the provisions related to confidentiality contained within this Agreement, Argent and Vertical acknowledge and agree that the Mutual Nondisclosure Agreement (the “CDA”) executed between the parties with an effective date of April 23, 2007, remains in lull force and effect.

11. Term; Termination.

11.1 Term. Subject to the provisions of this Section 11, the term of this Agreement and the marketing rights granted herein by Argent to Vertical shall be perpetual (as the word “perpetual” is qualified in Section 3.1 above) (“Term”).

11.2 Termination for Cause - Argent. Without prejudice to any other rights it may have hereunder or at law or in equity, Argent may terminate this Agreement by written notice to Vertical upon a breach by Vertical of the Supply Agreement that causes the Contract Manufacturer to terminate the Supply Agreement.

11.3 Termination for Cause - Either Party. Without prejudice to any other rights it may have hereunder or at law or in equity, either party may terminate this Agreement by written notice to the other party upon the occurrence of any of the following:

(a) the other party becomes insolvent, an order for relief is entered against the other party under any bankruptcy or insolvency laws or laws of similar import;

(b) the other party makes an assignment for the benefit of its creditors or a receiver or custodian is appointed for it or its business is placed under attachment, garnishment or other process involving a significant portion of its business; or

(c) after thirty (30) days written notice from the terminating party without cure by the breaching party of any material breach of this Agreement, including a failure to make any payment pursuant to the provisions of Section 8 of this Agreement on a timely basis.

11.4 Rights and Duties Upon Termination. Upon the termination of this Agreement, all rights granted by Argent to Vertical pursuant to Section 3.1 hereof shall revert to Argent and Argent shall have the right to receive any payments outlined in

Sections 8.1, 8.3 and 8.5 that have accrued as of the date of termination (or thereafter if Vertical sells any remaining inventory of the Products after the date of termination). In addition, in exchange for and in consideration of future payment of the Trademark Royalty described in Section 11.5 below, Vertical shall immediately assign to Argent (or Argent’s designee), on a fully paid-up basis (in the sense that there are no obligations other than payment over time of such Trademark Royalty), all rights in and to any Trademark(s) for the Products. Vertical further agrees to promptly execute any documents necessary to perfect such trademark rights in Argent (or Argent’s designee). In no event shall a termination of this Agreement be deemed a waiver of Argent’s right to receive any payment or other consideration that has accrued as of the date of termination and is owed to Argent by Vertical pursuant to Section 8 above. Sections of this Agreement that relate to confidentiality, indemnification, choice of law and jurisdiction, and dispute resolution, including, without limitation, Sections 9, 10, 11.4, 11.5, 11.6, 12.1 and 12.2, or that otherwise by their nature cannot be accomplished or fulfilled prior to termination or that relate to obligations of the parties accrued prior to termination, shall survive any termination of this Agreement.

11.5 Trademark Royalty. Argent shall pay Vertical a yearly royalty in the amount of [***] of its Net Sales of the Products in the Territory for the use of any Trademark(s) transferred pursuant Section 11.4 above on any of the Products (“Trademark Royalty”) and this shall be the only compensation, if applicable, that is to be paid by Argent to Vertical (or Optionee as defined in Section 11.6 below) with respect to the Products subsequent to the termination hereof. This obligation shall also apply to the Net Sales by any third party that has obtained rights from Argent to market the Products in the Territory and uses any of such Trademark(s) on any of the Products. For the avoidance of doubt, if such Trademark(s) are not used on the Products by Argent or any such third party, then no Trademark Royalty will be due Vertical hereunder.

11.6 Acquisition or Merger Termination Option - Vertical. In the event that Vertical is acquired or merged into NEWCO (as that term is defined in Section 8.5 above), NEWCO (and/or Vertical if Vertical remains as a operating entity) (NEWCO and/or Vertical are hereinafter for the purposes of this Section 11.6 referred to individually or collectively as the “Optionee”, unless Vertical is specifically referred to individually) shall have the option, but not the obligation, to return all rights in and to the Products that have been granted to Vertical under Section 3.1 hereof according to the following conditions:

11.6.1 NEWCO’s right to terminate under this Section 11.6 will only become operative if the prescription sales of the Products, as determined by Wolters Kluwer’s Source Pharmaceutical Monthly Retail Audit, have exceeded Three Million Dollars ($3,000,000) for the twelve (12) month period immediately preceding the first day of the month in which NEWCO elects to exercise the option described in this Section 11.6.

11.6.2 If the condition of Section 11.6.1 above is satisfied, and if Optionee elects to exercise its option to terminate this Agreement under the terms of this Section 11.6, and if Optionee confirms to Argent that the Supply Agreement for the Products has been terminated or will be terminated concurrently with the termination of this Agreement, then Argent agrees to allow Optionee to terminate this Agreement upon sixty (60) days written notice from Optionee.

11.6.3 If Optionee exercises its right to terminate this Agreement under the provisions of this Section 11.6, then upon such termination hereof Argent will have reacquired all of the marketing rights to the Products that it granted to Vertical pursuant hereto, and thus Argent will be free to commercialize the Products in the Territory itself or to enter into one or more new marketing rights agreements with third parties to commercialize the Products in the Territory and Optionee shall have no further residual rights of any kind or nature in and to the Products from that point forward, except the right to receive any Trademark Royalty as may be applicable under Section 11.5 above or the payment for any inventory of unsold Products that is purchased pursuant to Section 11.6.5 below.

11.6.4 If Optionee exercises its right to terminate this Agreement under the provisions of this Section 11.6, Optionee shall continue to be responsible for any product returns of Products sold by Optionee, any governmental discounts, rebates and chargebacks or other claims that may be related to the Products sold in the Territory by Optionee, including, but not limited to, Product liability claims, for example, pursuant to the indemnifications pertaining thereto as set forth in Section 10 above.

11.6.5 If Optionee exercises its right to terminate this Agreement under the provisions of this Section 11.6, Argent shall have the right, in Argent’s sole discretion, but not the obligation, to purchase any amount of the inventories of unsold Products owned and held by Optionee. Any such inventory of the Products that Argent may decide to purchase from Optionee shall be sold to Argent at a price not greater than the price paid by Optionee for the Products under the Supply Agreement and shall only be shipped to Argent (or Argent’s designee) as is directed by Argent in writing.

11.6.6 If Optionee exercises its right to terminate this Agreement under the provisions of this Section 11.6, Optionee agrees to transfer, sell and otherwise convey to Argent (or Argent’s designee) all rights in and to the Trademark(s) for the Products as set forth in Section 11.5 above.

11.6.7 If Optionee exercises its right to terminate this Agreement under the provisions of this Section 11.6, any payment obligation under Section 8 of this Agreement, incurred by Optionee up to, and including, the date of termination hereof, shall be promptly paid as of the date of termination. Failing that, Argent shall have the right, but not the obligation, to invalidate the termination of this Agreement under this Section 11.6. For the avoidance of doubt, Optionee will then remain liable for any royalties as set forth in Section 8 above, including, without limitation, any Minimum Annual Royalty as specified in Sections 8.3.2 and 8.3.3 above. This remedy shall be in addition to any other remedies that Argent may have at law or in equity with respect to the Optionee’s failure to comply with its obligations set forth in this Section 11.6.

12. Miscellaneous.

12.2.4 Nothing contained in this Section shall be construed as a waiver by either party of any claims or rights that it may have at law or in equity or prohibit or prevent a party from seeking relief at law or in equity (including, without limitation, injunctive relief). Notwithstanding the foregoing, no proceeding regarding a dispute may be brought in a court of law without first exhausting the Representative Executive dispute resolution procedure set forth in Section 12.2.1, the mediation procedure set forth in Section 12.2.2, and the arbitration procedure set forth in Section 12.2.3, in that order.
