SECTION 1.01.Closing. The closing of the Transactions (the “Closing”) shall take place at the offices of Covington & Burling LLP, The New York Times Building, 620 Eighth Avenue, New York, New York 10018, at 10:00 a.m. New York City time on the second Business Day following the date on which there first occurs the satisfaction (or, to the extent permitted, the waiver) of the conditions set forth in Article VII (other than any conditions which by their nature are intended to be satisfied at the Closing, but subject to their satisfaction or waiver at such time) or at such other place, time and date as may be agreed by the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative; provided, however, that notwithstanding the satisfaction (or, to the extent permitted, waiver) of the conditions set forth in Article VII with respect to the Closing, if the Marketing Period has not ended at the time of the satisfaction (or, to the extent permitted, waiver) of such conditions (other than any conditions which by their nature are intended to be satisfied at the Closing, but subject to their satisfaction or waiver at such time), the Closing shall occur instead on the date following the satisfaction or waiver of such conditions that is the earlier of (i) any Business Day during the Marketing Period specified by the Vertical/Trigen Shareholders’ Representative to the Osmotica Shareholders’ Representative on no less than two Business Days’ written notice to the Osmotica Shareholders or (ii) two Business Days following the final day of the Marketing Period; provided, however, that if the Marketing Period has ended prior to the End Date and such date in the foregoing clause (ii) would cause the Closing to occur after the End Date, then the Closing shall for purposes of the

3

foregoing clause (ii) occur on the End Date. The date on which the Closing occurs is referred to in this Agreement as the “Closing Date”.

SECTION 1.02.Transactions.

(a)Subject to the provisions of this Agreement, the parties hereto shall, and shall cause their respective affiliates to, take such steps as are necessary to effect the Transactions contemplated to be effected by such party or its affiliates specifically as described on Annex 1 or as otherwise mutually agreed by the Osmotica Shareholders’ Representative, on the one hand, and the Vertical/Trigen Shareholders’ Representative, on the other hand. If the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative agree in writing to a deviation from Annex 1 in accordance with this Section 1.02(a) (in which case the parties shall cause Annex 1 to be revised accordingly), then for purposes of this Agreement, all references to Annex 1 shall be deemed to be references to Annex 1 as so revised. Unless otherwise specifically provided in this Agreement, the Transactions set forth in Annex 1 shall be deemed to occur in the order set forth therein, as close in time as is reasonably practicable.

(b)For purposes of the Transactions, the principal amount of the Osmotica Shareholder Note shall be equal to (i) $325,000,000, minus (ii) the amount of Estimated Osmotica Indebtedness, minus (iii) the amount, if any, by which Estimated Osmotica Closing Working Capital is less than $6,250,000 (such amount, “Osmotica Target Working Capital”), plus (iv) the amount, if any, by which Estimated Osmotica Closing Working Capital exceeds Osmotica Target Working Capital.

(c)Each party hereto shall make available to the other parties hereto, in a timely manner for review and comment, all drafts of the material documents governing or effecting the Transactions as set forth in Annex 1, which shall at a minimum include the documents specified in such Annex 1 (the “Material Transaction Documents”), in each case, to the extent prepared by such party or its Representatives, and shall consider in good faith all reasonable comments provided by any other party or its Representatives to such document and instruments.

SECTION 1.03.Osmotica Adjustments.

(a)Osmotica Pre-Closing Estimate. At least three and not more than five Business Days prior to the anticipated Closing Date, Osmotica shall deliver to Vertical/Trigen a statement (the “Osmotica Estimated Closing Statement”), which shall include reasonable supporting detail as to each of the calculations set forth therein, of Osmotica’s good faith estimate of Osmotica Closing Working Capital (such estimate, “Estimated Osmotica Closing Working Capital”), Osmotica Closing Indebtedness (such estimate, “Estimated Osmotica Indebtedness”) and the LTIP Amount (such estimate, “Estimated LTIP Amount”). If Vertical/Trigen objects in good faith to any such estimate provided by Osmotica, then the parties will cooperate in good faith to resolve any such objection; provided, that if such objection is not resolved within two Business Days following the receipt of any such objection by Osmotica, then Osmotica shall make a good faith determination with respect to such objection and shall modify the Osmotica Estimated Closing Statement to take such objection into account; provided, further, that the parties agree that in no event shall the Closing be delayed as a result of the discussions contemplated by this sentence.

4

(b)Osmotica Retained Cash. On or before the Business Day prior to the Closing Date, the Osmotica Shareholders shall cause all cash held by the Osmotica Companies as of such date to be distributed to the Osmotica Shareholders or to be used to pay off Indebtedness, except for an aggregate amount of cash equal to the sum of (a) $4,000,000 (the “Osmotica Holdback Amount”), which amount shall be retained by the applicable Osmotica Companies until the Osmotica Net Adjustment Amount has been finally determined in accordance with Sections 1.04(d) and 1.04(g) and, if applicable, all or any portion of such amount is released in accordance with Section 1.04(g), and (b) the Estimated LTIP Amount, which amount shall be retained by the Osmotica Companies to cover payment obligations of New HoldCo and its subsidiaries in respect of the Osmotica LTIP after the Closing.

(c)Osmotica Closing Statement. Within 60 days after the Closing Date, the Osmotica Shareholders’ Representative shall prepare and deliver, or cause the Osmotica Companies’ accountants to prepare and deliver, to the Vertical/Trigen Shareholders’ Representative a statement (the “Osmotica Closing Statement”), which shall include reasonable supporting detail as to each of the calculations set forth therein, of Osmotica Working Capital as of 11:59 p.m. New York City time on the last day prior to the Closing Date (“Osmotica Closing Working Capital”), Osmotica Indebtedness as of 11:59 p.m. New York time on the last day prior to the Closing Date (“Osmotica Closing Indebtedness”) and the LTIP Amount. For purposes of the preparation of the Osmotica Closing Statement, the Vertical/Trigen Shareholders shall (and shall authorize New HoldCo and its applicable subsidiaries to), upon request, provide the Osmotica Shareholders’ Representative, and its Representatives (i) any information relating to the Osmotica Companies reasonably requested in connection with its preparation of the Osmotica Closing Statement and (ii) reasonable access during normal business hours to the personnel, properties, books and records of and relating to the Osmotica Companies (including any taking and preparing of physical counts of inventory).

(d)Objections; Resolution of Disputes.

(i)Unless the Vertical/Trigen Shareholders’ Representative notifies the Osmotica Shareholders’ Representative in writing within 30 days (such 30-day period, the “Objection Period”) after delivery of the Osmotica Closing Statement of any objection to the computation of Osmotica Closing Working Capital, Osmotica Closing Indebtedness or the LTIP Amount set forth therein (a “Notice of Objection”), the Osmotica Closing Statement shall become final and binding. Following the delivery of the Osmotica Closing Statement and for purposes of the Vertical/Trigen Shareholders’ Representative’s review of such Osmotica Closing Statement and preparation of any Notice of Objection, the Osmotica Shareholders’ Representative shall permit the Vertical/Trigen Shareholders’ Representative and its Representatives to review the working papers of the Osmotica Shareholders’ Representative and its accountants (subject to the execution and delivery of customary access letters) relating to such Osmotica Closing Statement and, at the Vertical/Trigen Shareholders’ Representative’s request, shall (and shall authorize New HoldCo and its applicable subsidiaries to) provide the Vertical/Trigen Shareholders’ Representative and its Representatives (A) any information relating to the Osmotica Companies or the Vertical/Trigen Companies, as the case may be, reasonably requested in connection with its review of the Osmotica Closing Statement and (B) reasonable access during normal business hours to the personnel, properties, books and records of and relating to the Osmotica Companies or the Vertical/Trigen Companies, as the case may be (including any taking and preparing of physical

5

counts of inventory). Any Notice of Objection shall specify the basis for the objections set forth therein.

(ii)If the Vertical/Trigen Shareholders’ Representative provides a Notice of Objection to the Osmotica Shareholders’ Representative within the applicable Objection Period, the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative shall, during the 30-day period following the Osmotica Shareholders’ Representative’s receipt of the Notice of Objection (such 30-day period, the “Resolution Period”), attempt in good faith to resolve such objections. During the Resolution Period, the Osmotica Shareholders’ Representative and its Representatives shall be permitted to review the working papers of the Vertical/Trigen Shareholders’ Representative and its accountants (subject to the execution and delivery of customary access letters) relating to the Notice of Objection and the basis therefor. If the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative are unable to resolve all such objections within the Resolution Period, the matters remaining in dispute shall be submitted to Ernst & Young LLP (or, if such firm declines or is unable to act, to another internationally recognized independent accounting firm mutually agreed upon by the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative (such agreed firm being the “Independent Expert”)). The Independent Expert shall be engaged pursuant to an engagement letter among Vertical/Trigen and the Independent Expert. The Independent Expert shall be instructed, pursuant to such engagement letter, to resolve only those matters set forth in the Notice of Objection remaining in dispute and not to otherwise investigate any matter independently, and to make its determinations in accordance with the terms of this Agreement. The Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative each agree to furnish to the Independent Expert such individuals and such information, books and records as may be reasonably required by the Independent Expert to make its final determination. Vertical/Trigen shall also instruct the Independent Expert to render its reasoned written decision as promptly as practicable but in no event later than 30 days from the date that information related to the unresolved objections was presented to the Independent Expert by the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative.

The resolution of disputed items by the Independent Expert shall be final and binding on the parties, and the determination of the Independent Expert shall constitute an arbitral award that is final, binding and non-appealable and upon which a judgment may be entered by a court having jurisdiction thereover. The fees and expenses of the Independent Expert shall be borne by Vertical/Trigen. After the final determination of Osmotica Closing Working Capital, Osmotica Closing Indebtedness or the LTIP Amount and payment of the Osmotica Net Adjustment Amount pursuant to Section 1.04(g), the Vertical/Trigen Shareholders shall have no further right to make any claims against the Osmotica Shareholders or any of their respective affiliates in respect of any element of Osmotica Closing Working Capital, Osmotica Closing Indebtedness or the LTIP Amount or any payment made pursuant to Section 1.04(g).

(e)Osmotica Working Capital. The term “Osmotica Working Capital” means Osmotica Current Assets minus Osmotica Current Liabilities. The terms “Osmotica Current

6

Assets” and “Osmotica Current Liabilities” mean those consolidated current assets (excluding cash) and consolidated current liabilities of the Osmotica Companies that are specifically set forth within “Osmotica Current Assets” and “Osmotica Current Liabilities” in the sample calculation of Osmotica Working Capital set forth on Exhibit F, and calculated by reference to the corresponding line items of the sample calculation of Osmotica Working Capital set forth on Exhibit F and in accordance with International Financial Reporting Standards as adopted by the European Union (“IFRS”) (it being understood, that, with respect to such calculations, but not the identity of the line items of Osmotica Current Assets and Osmotica Current Liabilities included in Osmotica Working Capital, IFRS shall be applied in a manner that is consistent with that used in the sample calculation set forth on Exhibit F), except that (i) current and deferred Income Tax liabilities, current and deferred Income Tax assets, deferred Non-Income Tax liabilities and deferred Non-Income Tax assets shall not be taken into account in determining Osmotica Working Capital, (ii) Osmotica Indebtedness shall not be taken into account in determining Osmotica Working Capital, (iii) any impact of changes in assets or liabilities as a result of purchase accounting adjustments or other changes arising from or resulting as a consequence of the Transactions shall not be taken into account in determining Osmotica Working Capital, (iv) the New HoldCo Expenses shall not be taken into account in determining Osmotica Working Capital, (v) any receivables from or payables to shareholders, directors, affiliates or related parties of the Osmotica Companies shall not be taken into account in determining Osmotica Working Capital and (vi) Ontinua ER inventory shall not be taken into account in determining Osmotica Working Capital. The Osmotica Working Capital adjustment contemplated by this Section 1.04 is intended to show the change in Osmotica Working Capital from the Osmotica Target Working Capital to Osmotica Closing Working Capital, and such change can only be measured if the calculation is done in the same way, using the same methods, for both amounts.

(f)Post-Closing Books and Records. On the Closing Date, New HoldCo shall conduct the businesses of the Osmotica Companies and the Vertical/Trigen Companies in the ordinary course in a manner substantially consistent with past practice (except for the occurrence of the Closing and the consummation of the Financing and the Transactions), and following the Closing, New HoldCo shall not take any action (or permit any action to be taken) with respect to the accounting books and records of the Osmotica Companies on which the Osmotica Closing Statement is to be based that would affect such Osmotica Closing Statement.

(g)Osmotica Adjustments; Release of Osmotica Holdback Amount.

(i)If the Osmotica Closing Indebtedness as finally determinedin accordance with Section 1.04(d) (the “Actual Osmotica Indebtedness”) is less than the Estimated Osmotica Indebtedness, an amount equal to such difference shall be due to the Osmotica Shareholders and payable in accordance with, and subject to, Section 1.04(g)(iv). If the Estimated Osmotica Indebtedness is less than the Actual Osmotica Indebtedness, an amount equal to such shortfall shall be due to New HoldCo and payable in accordance with, and subject to, Section 1.04(g)(iv).

(ii)If (A) the Osmotica Closing Working Capital as finally determined in accordance with Section 1.04(d) (the “Actual Osmotica Working Capital”) is greater than the Estimated Osmotica Closing Working Capital, then an amount equal to the excess of the Actual Osmotica Working Capital over the Estimated Osmotica Closing Working Capital shall be due to the Osmotica Shareholders and payable in accordance with, and subject to, Section 1.04(g)(iv),

7

(B) the Actual Osmotica Working Capital is less than the Estimated Osmotica Closing Working Capital, then an amount equal to the excess of the Estimated Osmotica Closing Working Capital over the Actual Osmotica Working Capital shall be due to New HoldCo and payable in accordance with, and subject to, Section 1.04(g)(iv), and (C) the Actual Osmotica Working Capital is equal to the Estimated Osmotica Closing Working Capital, then no adjustment payments shall be due in respect of Osmotica Working Capital.

(iii)If the LTIP Amount as finally determined in accordance with Section 1.04(d) (the “Actual LTIP Amount”) is less than the Estimated LTIP Amount, an amount equal to such difference shall be due to the Osmotica Shareholders and payable in accordance with, and subject to, Section 1.04(g)(iv). If the Estimated LTIP Amount is less than the Actual LTIP Amount, an amount equal to such shortfall shall be due to New HoldCo and payable in accordance with, and subject to, Section 1.04(g)(iv).

(iv)Any amounts owing and payable between New HoldCo and the Osmotica Shareholders pursuant to any of Sections 1.04(g)(i) through 1.04(g)(iii) shall be set-off against any other amount or amounts owing and payable between such parties pursuant to such sections, such that only a net amount (the “Osmotica Net Adjustment Amount”) shall be paid. The Osmotica Net Adjustment Amount shall be calculated without duplication of any assets or liabilities included therein pursuant to this Agreement. If the Osmotica Net Adjustment Amount is payable to New HoldCo and the Osmotica Net Adjustment Amount is less than the Osmotica Holdback Amount, then New HoldCo shall promptly pay, or cause to be paid, to the Osmotica Shareholders (on a pro rata basis, in accordance with their Osmotica Pro Rata Percentages) the amount by which the Osmotica Holdback Amount exceeds the Osmotica Net Adjustment Amount, and New HoldCo shall retain the balance of the Osmotica Holdback Amount. If the Osmotica Net Adjustment Amount is payable to New HoldCo and the Osmotica Net Adjustment Amount exceeds the Osmotica Holdback Amount, then New HoldCo shall retain the balance of the Osmotica Holdback Amount and the Osmotica Shareholders shall be liable, severally (according to their Osmotica Pro Rata Percentages) but not jointly, to New HoldCo for the amount by which the Osmotica Net Adjustment Amount exceeds the Osmotica Holdback Amount (“Osmotica Excess Adjustment Amounts”). The portion of any Osmotica Excess Adjustment Amount for which any Osmotica Shareholder is liable pursuant to this Section 1.04(g)(iv) shall be paid by such Osmotica Shareholder in cash, by wire transfer of immediately available funds, to New HoldCo within five (5) Business Days of becoming due. In the event such payment is not timely received by New HoldCo, New HoldCo may elect, in its sole discretion, to instead set off any such amounts against amounts otherwise distributable to the applicable Osmotica Shareholder. If the Osmotica Net Adjustment Amount is payable to the Osmotica Shareholders, then New HoldCo shall promptly pay, or cause to be paid, to the Osmotica Shareholders (on a pro rata basis, in accordance with their Osmotica Pro Rata Percentages) the Osmotica Net Adjustment Amount and the Osmotica Holdback Amount.

59

(i)the current directors and officers of the Osmotica Companies with an insurance and indemnification policy that provides coverage for events occurring prior to the Closing Date (the “Osmotica D&O Insurance”) that is no less favorable than the existing policies of the Osmotica Companies or, if insurance coverage that is no less favorable is unavailable, the best available coverage; provided, that New HoldCo shall not be required to pay an annual premium for the Osmotica D&O Insurance in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement (it being understood that New HoldCo shall nevertheless be obligated to provide as much coverage as may be obtained for such 300% amount); provided, further, that Osmotica may prior to the Closing Date substitute therefor a single premium tail coverage with respect to Osmotica D&O Insurance with an annual cost not in excess of three hundred percent (300%) of the last annual premium paid prior to the date of this Agreement; and

SECTION 5.11.[Reserved]

SECTION 5.12.Financing.

(a)(i)  Subject to the terms and conditions of this Agreement, Vertical/Trigen shall, and shall cause its subsidiaries to, use their respective reasonable best efforts to obtain the Financing on the terms and conditions (including the “market flex” provisions), contained in the Commitment Letters as promptly as practicable taking into account the anticipated Closing Date (after giving effect to and contemplating the Marketing Period) and shall not permit any amendment or modification to be made to, or any waiver of any provision under, the Commitment Letters, in each case, without the prior written consent of the Osmotica Shareholders’ Representative (such consent not to be unreasonably withheld, conditioned or delayed); provided, that, without the consent of the Osmotica Shareholders’ Representative, Vertical/Trigen may (A)

60

amend the Commitment Letters to add lenders, lead arrangers, bookrunners, syndication agents, additional purchasers or similar entities who had not executed the Commitment Letters as of the date hereof, or (B) otherwise modify or amend, or agree to any waivers in respect of, either Commitment Letter so long as, in each case, (1) such action would not reasonably be expected to (x) reduce the aggregate amount of the Financing (including by increasing the amount of fees to be paid or original issue discount) in a manner that would cause the representation set forth in Section 4.08(c) to be untrue or inaccurate, (y) delay or prevent the Closing, or (z) impair the availability of the Financing on the Closing Date, and (2) the terms of such amendment, modification or waiver are not less beneficial to Vertical/Trigen, with respect to conditionality or enforcement, than those in the Commitment Letters as in effect on the date of this Agreement. Vertical/Trigen shall promptly deliver to Osmotica copies of any such amendment, modification or waiver, and shall promptly consult with Osmotica in connection with any proposed amendment, modification or waiver pursuant to the preceding clause (B). For purposes of this Section 5.12 and Sections 4.16 and 4.21, references to the “Financing” shall include the financing contemplated by the Commitment Letters as permitted to be amended or modified by this Section 5.12(a), and references to the “Commitment Letters” shall include such documents as permitted to be amended or modified by this Section 5.12(a).

(ii)Vertical/Trigen shall, and shall cause its subsidiaries to, use their respective reasonable best efforts (A) to maintain in effect the Commitment Letters, (B) to negotiate and enter into definitive agreements with respect to the Commitment Letters on the terms and conditions (including the “market flex” provisions) contained in the Commitment Letters (or on other terms acceptable to Vertical/Trigen which would not (x) reduce the aggregate amount of the Financing, (y) impose new or additional conditions precedent to the receipt of the Financing or (z) otherwise reasonably be expected to impair or delay the availability of the Financing), (C) to satisfy on a timely basis all conditions to funding in the Commitment Letters and such definitive agreements with respect thereto that are within its control and, if all the conditions to each party’s obligations under Article VII (other than those conditions which by their nature are intended to be satisfied on the Closing Date or the failure of which to be satisfied is attributable primarily to a breach by the Vertical/Trigen Shareholders or Vertical/Trigen of their representations, warranties, covenants and agreements contained in this Agreement) have been satisfied or waived, consummate the Financing, including using reasonable best efforts to cause the Lenders and the other persons committing to fund the Financing to fund the Financing at the Closing, (D) to enforce its rights under the Commitment Letters and (E) to comply with all of its obligations under the Commitment Letters. Vertical/Trigen shall keep Osmotica informed on a current basis and in reasonable detail of the status of its and its affiliates’ efforts to arrange the Financing and provide promptly to Osmotica copies of drafts of the material definitive agreements for the Financing, and thereafter (promptly upon becoming available) complete and correct copies of the executed versions of all such agreements. Without limiting the generality of the foregoing, Vertical/Trigen shall give Osmotica prompt notice (x) of any material breach or default (or any event that, with or without notice, lapse of time or both, would reasonably be expected to give rise to any material breach or default) by any party to either Commitment Letter or definitive agreements related to the Financing of which Vertical/Trigen or any of its affiliates become aware, (y) of the receipt of any written notice from any Debt Financing Source with respect to any (1) actual or potential breach, default, termination or repudiation by any party to the Commitment Letters or definitive agreements related to the Financing or (2) material dispute or disagreement between or among any parties to any provisions of the Commitment Letters or definitive agreements related to the Financing, and (z) if

61

at any time for any reason Vertical/Trigen believes in good faith that it or its affiliates will not be able to obtain all or any portion of the Financing on the terms and conditions, in the manner or from the sources contemplated by the Commitment Letters or definitive agreements related to the Financing. As soon as reasonably practicable, but in any event within two Business Days of the date Osmotica delivers to Vertical/Trigen a written request, Vertical/Trigen shall provide any information reasonably requested by Osmotica relating to any circumstance referred to in clauses (x), (y) or (z) of the immediately preceding sentence. Upon the occurrence of any circumstance referred to in clauses (x), (y)(1) or (z) of the second preceding sentence, or if any portion of the Financing otherwise becomes unavailable (including taking into account the “market flex” provisions) or Vertical/Trigen becomes aware of any event or circumstance that would reasonably be expected to make any portion of the Financing becoming so unavailable, and such portion is reasonably required to fund the fees, expenses and other amounts contemplated to be paid by Vertical/Trigen or its affiliates pursuant to this Agreement, Vertical/Trigen shall, and shall cause its affiliates to, use their respective reasonable best efforts to arrange and obtain in replacement thereof alternative financing from alternative sources in an amount sufficient to consummate the Transactions with terms and conditions not materially less favorable to Vertical/Trigen or its affiliates (taking into account the “market flex” provisions as set forth in the Commitment Letters) than the terms and conditions set forth in the Commitment Letter, as applicable, as promptly as reasonably practicable following the occurrence of such event. Vertical/Trigen shall deliver to Osmotica complete and correct copies of all Contracts or other arrangements (when available) pursuant to which any such alternative source shall have committed to provide any portion of the Financing. Each of the Vertical/Trigen Shareholders and Vertical/Trigen acknowledges and agrees that the obtaining of the Financing, or any alternative financing, is not a condition to the obligations of the Vertical/Trigen Shareholders or Vertical/Trigen to consummate the Closing.

(b)Subject to the applicable provisions of Section 5.02(a) and the remaining provisions of this Section 5.12, prior to the Closing, Osmotica and New HoldCo shall, and shall cause their respective subsidiaries to, and shall use their respective reasonable best efforts to cause their respective Representatives to, in each case, at the sole expense of the Vertical/Trigen Shareholders or, if the Closing occurs, at the sole expense of New HoldCo or its subsidiaries, reasonably cooperate with Vertical/Trigen and its Representatives in connection with Vertical/Trigen’s arrangement of the Financing, which cooperation shall consist of, at the reasonable request of Vertical/Trigen, using reasonable best efforts to: (i) to cooperate with Vertical/Trigen’s and its Financing sources’ due diligence with respect to the Osmotica Companies to the extent customary and reasonable, (ii) to assist in the execution and delivery as of the Closing of any pledge and security documents, other definitive financing documents, or other certificates or documents as may be reasonably requested by Vertical/Trigen and otherwise facilitating the pledging of collateral, (iii) to take reasonable actions necessary to (A) permit the prospective lenders involved in the Financing to evaluate the applicable Osmotica Companies’ current assets, cash management and accounting systems, policies and procedures relating thereto for the purposes of establishing collateral arrangements and (B) establish bank and other accounts and blocked account agreements and lock box arrangements in connection with the foregoing, (iv) to take all corporate actions reasonably necessary to permit the consummation of the Financing and to permit the proceeds thereof to be available as of the Closing, (v) upon Vertical/Trigen’s prior written request, to furnish Vertical/Trigen and its Debt Financing Sources at least three Business Days prior to the Closing with all reasonable documentation or other information relating to the New HoldCo or the Osmotica Companies required by regulatory authorities with respect to the Financing under

62

applicable “know your customer” and anti-money laundering rules and regulations, including the PATRIOT Act, (vi) to furnish, as promptly as reasonably practical, Vertical/Trigen and its Debt Financing Sources with the information relating to the Osmotica Companies in paragraph 8 of Exhibit C to each Commitment Letter (the “Required Financial Information”) and such other financial and other information regarding the Osmotica Companies as may be reasonably requested by Vertical/Trigen, (vii) to assist with the preparation of reasonable and customary materials for bank information memoranda and similar documents required or reasonably requested by the Debt Financing Sources in connection with the Financing and executing and delivering customary authorization letters and management representation letters, (viii) to obtain customary debt pay-off letters and releases in respect of indebtedness for borrowed money which is required to be paid off hereunder, (ix) to assist with the preparation of all pro forma and synergy information reasonably requested for the Financing, and (x) to cause the taking of corporate and other actions by the Osmotica Companies reasonably necessary to permit the consummation of the Financing on the Closing Date and to permit the proceeds thereof to be made available as of the Closing Date; it being understood and agreed, that (A) no such corporate or other action will take effect prior to the Closing Date and (B) any such corporate or other action will only be required of the directors, members, partners, managers or officers of the Osmotica Companies who retain their respective positions as of the Closing. Notwithstanding anything to the contrary in this Section 5.12(b), (1) none of the Osmotica Shareholders, Osmotica or New HoldCo, or any of their respective affiliates, shall be required to take any action that would unreasonably interfere with their ongoing operations, (2)  none of the Osmotica Shareholders or any of their respective affiliates (except for, after the Closing, the applicable Osmotica Companies), shall have any obligation under any agreement, certificate, document or instrument proposed by Vertical/Trigen under this Section 5.12(b), (3)  no obligation of any of the applicable Osmotica Companies under any such agreement, certificate, document or instrument shall be effective until the Closing and (4) none of the Osmotica Shareholders nor any of their respective affiliates (including, prior to the Closing, New HoldCo and the Osmotica Companies) shall be required to pay any commitment or other fee or incur any cost, expense or other liability that is not simultaneously reimbursed by the Vertical/Trigen Shareholders in connection with the Financing prior to the Closing. Vertical/Trigen or, if the Closing occurs, New HoldCo or its subsidiaries shall, promptly upon request by the Osmotica Shareholders, severally (but not jointly or jointly and severally) reimburse, or cause its subsidiaries to reimburse, the Osmotica Shareholders for all reasonable and documented out-of-pocket costs and expenses incurred by the Osmotica Shareholders and their respective affiliates (including, prior to the Closing, New HoldCo or any of the Osmotica Companies) in connection with the cooperation to be provided by Osmotica and New HoldCo pursuant to Section 5.12(b). Whether or not the Closing occurs, Vertical/Trigen shall indemnify and hold harmless the Osmotica Shareholders, their respective affiliates (including, prior to the Closing, New HoldCo or any of the Osmotica Companies) and their respective Representatives, in each case, acting on behalf of the Osmotica Shareholders or their respective affiliates (including, prior to the Closing, New HoldCo or any of the Osmotica Companies) for and against any and all Losses suffered or incurred by them in connection with the arrangement of the Financing and any information utilized in connection therewith; provided, however, that the foregoing shall not apply to the extent such Losses arose out of or resulted from (A) information provided by or on behalf of the Osmotica Shareholders, the Osmotica Companies or any of their respective affiliates or any of their respective representatives or (B) any Osmotica Shareholder’s, Osmotica Company’s, New HoldCo’s or any of their respective affiliates’ or representatives’ willful misconduct or gross

63

negligence. The Osmotica Companies and their Representatives shall be given reasonable opportunity to review and comment upon any information memoranda or similar documents, or any similar materials, that include information about any of the Osmotica Companies prepared in connection with the Financing. The Osmotica Companies consent to the reasonable use of the Osmotica Companies’ logos in connection with any Financing in a manner customary for such financing transactions; provided, that such logos are used solely in a manner that is (x) not intended to or reasonably likely to harm or disparage the reputation or goodwill of the Osmotica Companies and (y) is otherwise consistent with the use of the Vertical/Trigen Companies’ logos in connection with any Financing; it being understood, that Vertical/Trigen shall provide drafts to Osmotica of how the Osmotica Companies’ logos are proposed to be used in connection with the Financing and consider in good faith any comments or concerns raised by Osmotica with respect to such use of such logos.

or failure to perform (A) would give rise to the failure of a condition set forth in Sections 7.01 or 7.03 and (B) cannot be cured by the Vertical/Trigen Shareholders or Vertical/Trigen, as applicable, by the End Date, or if capable of being cured, shall not have commenced to have been cured by the earlier of (1) the 15th day following receipt by the Vertical/Trigen Shareholders’ Representative of written notice of such breach or failure to perform from the Osmotica Shareholders’ Representative stating the Osmotica Shareholders’ Representative’s intention to terminate this Agreement pursuant to this Section 8.01(d)(i) and the basis for such termination and (2) the End Date; provided, however, that the Osmotica Shareholders’ Representative shall not have the right to terminate this Agreement pursuant to this Section 8.01(d)(i) if any of the Osmotica Shareholders, Osmotica or New HoldCo is then in breach of any representations, warranties, covenants or other agreements hereunder which breach would result in a condition to Closing set forth in Sections 7.01 or 7.02 not being satisfied (other than those conditions (1) which by their nature are intended to be satisfied at the Closing or (2) the failure of which to be satisfied is attributable primarily to a breach by the Vertical/Trigen Shareholders or Vertical/Trigen of their respective representations, warranties, covenants and agreements contained in this Agreement); or

(ii)if (A) the Marketing Period has ended, (B) all of the conditions set forth in Sections 7.01 and 7.02 have been satisfied or waived (other than those conditions (1) which by their nature are intended to be satisfied at the Closing or (2) the failure of which to be satisfied is attributable primarily to a breach by the Vertical/Trigen Shareholders of their respective representations, warranties, covenants and agreements contained in this Agreement), (C) the Osmotica Shareholders’ Representative has irrevocably confirmed by notice to the Vertical/Trigen Shareholders’ Representative that the Osmotica Shareholders, Osmotica and New HoldCo stand ready, willing and able to consummate the Transactions and (D) the Transactions shall not have been consummated at the time required by Section 1.01 due to a Financing Failure (assuming for such purpose that all of the conditions set forth in Sections 7.01, 7.02 and 7.03 have been satisfied or waived).

SECTION 8.02.Effect of Termination.

(a)In the event of termination of this Agreement by the Osmotica Shareholders’ Representative or the Vertical/Trigen Shareholders’ Representative pursuant to Section 8.01, written notice thereof shall forthwith be given to the other party, specifying the provision hereof pursuant to which such termination is made, and this Agreement shall forthwith become null and void and of no further force and effect (other than the provisions of Section 5.06 (Publicity), the expense reimbursement and indemnification provisions of Section 5.12(c), this Article VIII (Termination), Section 11.03 (Expenses), Section 11.04 (Notices), Section 11.05 (Interpretation; Certain Definitions), Section 11.10 (Governing Law), Section 11.11 (Jurisdiction), Section 11.12 (Service of Process), Section 11.13 (Waiver of Jury Trial), Section 11.18 (Osmotica Shareholders’ Representative) and Section 11.19 (Vertical/Trigen Shareholders’ Representative) all of which shall survive termination of this Agreement), and there shall be no liability on the part of the Osmotica Companies, the Osmotica Shareholders, the Vertical/Trigen Companies or the Vertical/Trigen Shareholders or their respective affiliates or Representatives, except (i) as liability may exist pursuant to the sections specified in this Section 8.02(a) that survive such termination, (ii) that no such termination shall relieve any party from any liability to pay the fees, expenses and other amounts set forth in Section 8.03, if and when due in accordance with the provisions thereof, and (iii) that, except as otherwise provided in Section 8.03, no such termination shall relieve any

76

party from any liability arising out of any Willful Breach by such party of any representation or warranty of such party contained herein or any covenant or agreement of such party contained herein. “Willful Breach” means a deliberate act or a deliberate failure to act, which act or failure to act constitutes in and of itself a material breach of this Agreement, regardless of whether breaching was the conscious object of the act or failure to act. Notwithstanding anything to the contrary herein, the parties hereto agree that, in the event this Agreement is terminated by the Osmotica Shareholders’ Representative pursuant to Section 8.01(d)(i) in circumstances in which the Osmotica Shareholders’ Representative was not entitled to terminate this Agreement pursuant to Section 8.01(d)(ii), the Osmotica Shareholders, Osmotica, New HoldCo, and their respective affiliates shall only be entitled to seek monetary damages in connection therewith and only from the Vertical/Trigen Companies (and their successors and assigns), and, in such circumstances, none of the Osmotica Shareholders, Osmotica, New HoldCo, or any of their respective affiliates shall seek to recover any monetary damages directly from any of the Vertical/Trigen Shareholders or any of their affiliates (other than, for the avoidance of doubt, the Vertical/Trigen Companies).

(b)If the Transactions are terminated as provided herein (i) (A) the Vertical/Trigen Shareholders and Vertical/Trigen promptly shall, and shall cause each of their respective affiliates and Representatives to, return to Osmotica or destroy (such destruction to be confirmed in writing by Vertical/Trigen to Osmotica), all documents and other material received from Osmotica or any of its affiliates or Representatives relating to the transactions contemplated by this Agreement, whether so obtained before or after the execution hereof and (B) all information received by the Vertical/Trigen Shareholders, Vertical/Trigen or their respective affiliates or Representatives with respect to the businesses of Osmotica and its affiliates shall be treated in accordance with the Confidentiality Agreement, which shall remain in full force and effect notwithstanding the termination of this Agreement and (ii) (A) the Osmotica Shareholders and Osmotica promptly shall, and shall cause each of their respective affiliates and Representatives to, return to Vertical/Trigen or destroy (such destruction to be confirmed in writing by Osmotica to Vertical/Trigen), all documents and other material received from Vertical/Trigen or any of its affiliates or Representatives relating to the transactions contemplated by this Agreement, whether so obtained before or after the execution hereof and (B) all information received by the Osmotica Shareholders, Osmotica or their respective affiliates or Representatives with respect to the businesses of Vertical/Trigen and its affiliates shall be treated in accordance with the Confidentiality Agreement, which shall remain in full force and effect notwithstanding the termination of this Agreement.

SECTION 8.03.Termination Fee.

(a)(i) In the event that this Agreement is terminated by the Osmotica Shareholders’ Representative pursuant to Section 8.01(d)(ii), then Vertical/Trigen shall pay to the Osmotica Shareholders’ Representative a non-refundable termination fee of $30,000,000 in cash by wire transfer of same-day funds (the “Termination Fee”) within two Business Days following such termination.

(ii)In no event shall Vertical/Trigen be required to pay the Termination Fee on more than one occasion. In the event that the Osmotica Shareholders’ Representative shall receive full payment pursuant to this Section 8.03(a), together with the Collection Fees and Expenses pursuant to Section 8.03(b) and any fees and expenses payable pursuant to Section 11.15, if any,

77

(A) the receipt of the Termination Fee, together with the Collection Fees and Expenses, if any, shall be deemed to be liquidated damages for any and all Losses suffered or incurred by the Osmotica Shareholders, Osmotica, New HoldCo or any of their respective affiliates in connection with this Agreement, the Transactions (and the abandonment or termination thereof) or any matter forming the basis for such termination, and (B) none of the Osmotica Shareholders, Osmotica or New HoldCo nor any of its affiliates shall be entitled to bring or maintain any claim, action or proceeding against the Vertical/Trigen Shareholders, Vertical/Trigen, the Debt Financing Sources or any of their respective former, current or future general or limited partners, stockholders, controlling persons, managers, members, directors, officers, employees, agents or affiliates (the “Vertical/Trigen Related Parties”) arising out of or in connection with this Agreement, the Debt Commitment Letters, any of the transactions contemplated hereby or thereby (or the abandonment or termination thereof) or any matters forming the basis for such termination.

(b)The parties hereto acknowledge and agree that the agreements contained in this Section 8.03 are an integral part of the transactions contemplated by this Agreement, that the Termination Fee represents liquidated damages in a reasonable amount and not a penalty and that, without these agreements, none of the parties hereto would have entered into this Agreement. If Vertical/Trigen fails promptly to pay the Termination Fee when due, Vertical/Trigen shall pay the Osmotica Shareholders’ and their respective affiliates’ costs and expenses (including reasonable attorneys’ fees and expenses) in connection with seeking such payment, together with interest (calculated as simple interest) on the Termination Fee from the date such payment was required to be made hereunder until the date such payment was actually received by the Osmotica Shareholders’ Representative (whether before or after any insolvency or bankruptcy), at the prime lending rate of Bank of America at its principal office in New York City as in effect from time to time (collectively, the “Collection Fees and Expenses”).

(c)Notwithstanding anything to the contrary contained in this Agreement (but subject to the rights of the Osmotica Shareholders’ Representative set forth in Section 11.15), in the circumstances where the Termination Fee is owed and payable pursuant to Section 8.03(a)(i), the expense reimbursement and indemnification obligations of the Vertical/Trigen Shareholders and their respective affiliates under Section 5.12(b), and the reimbursement obligations under Section 8.03(b) (i.e., to the Collection Fees and Expenses) and Section 11.15, the Osmotica Shareholders’ Representative’s right to receive payment of the Termination Fee from Vertical/Trigen in respect thereof shall be the sole and exclusive remedy of the Osmotica Shareholders, Osmotica, New HoldCo or their respective affiliates against the Vertical/Trigen Related Parties for any Losses suffered as a result of the failure of the Transactions to be consummated in the circumstances where the Termination Fee is owed and payable pursuant to Section 8.03(a)(i), and upon payment of such amounts, none of the Vertical/Trigen Related Parties shall have any further liability or obligation relating to or arising out of this Agreement or the Transactions following the termination hereof. For the avoidance of doubt, (i) in the circumstances where the Termination Fee is owed and payable pursuant to Section 8.03(a)(i), none of the Osmotica Shareholders, Osmotica, New HoldCo, nor any of their respective affiliates will be entitled to monetary damages in excess of the amount of the Termination Fee (other than any indemnification or reimbursement pursuant to Section 5.12(b), or the reimbursement obligations under Section 8.03(b) (i.e., the Collection Fees and Expenses) and Section 11.15), and (ii) while the Osmotica Shareholders’ Representative may pursue both a grant of specific performance in accordance with the circumstances provided in Section 11.15 and the payment of the Termination Fee under Section 8.03(a), under no

78

circumstances shall the Osmotica Shareholders’ Representative, the Osmotica Shareholders or Osmotica be permitted or entitled to receive both a grant of specific performance of the type contemplated by the preceding sentence and money damages, including all or any portion of the Termination Fee.

SECTION 9.03.Indemnification Procedures.

(a)Third Party Claims. If any party (the “Indemnified Party”) receives written notice of the commencement of any Proceeding or the assertion of any claim by a third party or the imposition of any penalty or assessment (in each case other than with respect to Taxes) for which indemnity may be sought under Section 9.01 or Section 9.02 (a “Third Party Claim”), and such Indemnified Party intends to seek indemnity pursuant to this Article IX, the Indemnified Party

80

shall promptly (but no later than 30 days after receiving such notice) provide the other party (the “Indemnifying Party”) with written notice of such Third Party Claim, stating the nature, basis, the amount thereof (to the extent known or estimated, which amount shall not be conclusive of the final amount of such Third Party Claim), the method of computation thereof (to the extent known or estimated), any other remedy sought thereunder, any relevant time constraints relating thereto, and, to the extent practicable, any other material details pertaining thereto, along with copies of the relevant documents evidencing such Third Party Claim and the basis for indemnification sought. Failure of the Indemnified Party to give such notice will not relieve the Indemnifying Party from its indemnification obligations hereunder, except to the extent that the Indemnifying Party is actually prejudiced thereby. The Indemnifying Party will have 45 days from receipt of any such notice of a Third Party Claim to give notice to the Indemnified Party whether it is assuming and controlling the defense, appeal or settlement proceedings thereof with counsel of the Indemnifying Party’s choice. So long as the Indemnifying Party has assumed the defense, appeal or settlement proceedings of the Third Party Claim in accordance herewith, (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in (but not control) the defense, appeal or settlement proceedings of the Third Party Claim, (ii) the Indemnified Party will not admit any liability, file any papers or consent to the entry of any judgment or enter into any settlement agreement, compromise or discharge with respect to the Third Party Claim without the prior written consent of the Indemnifying Party and (iii) the Indemnifying Party will not admit to any wrongdoing by the Indemnified Party. The Indemnifying Party shall have the right to settle any Third Party Claim for which it obtains a full release of the Indemnified Party with respect to such Third Party Claim or to which settlement the Indemnified Party consents in writing (such consent not to be unreasonably withheld, conditioned or delayed). As to any Third Party Claim with respect to which the Indemnifying Party does not elect to assume control of the defense, the Indemnified Party will afford the Indemnifying Party an opportunity to participate in such defense, at its cost and expense, and will consult with the Indemnifying Party prior to settling or otherwise disposing of any of the same. The parties will act in good faith in responding to, defending against, settling or otherwise dealing with Third Party Claims. The parties will also cooperate in any such defense, appeal or settlement proceedings, and give each other reasonable access to all information relevant thereto. Whether or not the Indemnifying Party has assumed the defense, appeal or settlement proceedings with respect to a Third Party Claim, such Indemnifying Party will not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into or any judgment that was consented to by the Indemnified Party without the Indemnifying Party’s prior written consent (such consent not to be unreasonably withheld, conditioned or delayed).

(b)Other Claims. An Indemnified Party shall give the Indemnifying Party written notice of any matter that an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, within 30 days of such determination, stating the amount of the Loss, if known, and the method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises.

SECTION 9.04.Limitations on Indemnification. Notwithstanding anything to the contrary contained in this Agreement:

(a)(i)  The Osmotica Shareholders shall not have any liability under Section 9.01(a) unless the aggregate liability for Losses suffered by the Vertical/Trigen Indemnitees thereunder

(b)(i)  The Vertical/Trigen Shareholders shall not have any liability under Section 9.02(a) unless the aggregate liability for Losses suffered by the Osmotica Indemnitees thereunder exceeds $3,000,000, and then only to the extent of such excess, (ii) the Vertical/Trigen Shareholders’ aggregate maximum liability under Sections 9.02(a), 9.02(e) and 9.02(f) shall not exceed the amount then-available in the Vertical/Trigen Indemnification Escrow Account, and (iii) the Vertical/Trigen Shareholders shall not have any liability under Section 9.02(a) for any individual Loss of less than the Mini-Basket and such individual Losses shall not be aggregated for purposes of the preceding clauses (i) and (]); provided, that the limitations on liability in the foregoing clauses (i), (ii) and (iii) shall not apply (A) to the extent a breach of any representation or warranty of the Vertical/Trigen Shareholders or Vertical/Trigen contained in Article IV constitutes actual fraud by any Vertical/Trigen Shareholder or Vertical/Trigen, (B) to any breach of the Vertical/Trigen Fundamental Representations, or (C) for the avoidance of doubt, to any claims pursuant to Sections 9.02(b) through 9.02(d) (clauses (A) through (C), collectively, the “Osmotica Excluded Claims”), and Losses on account of Osmotica Excluded Claims instead shall not exceed $100,000,000 in the aggregate (such amount, the “Vertical/Trigen Excluded Claim Cap” and, together with the Osmotica Excluded Claim Cap, the “Excluded Claim Caps”)).

(c)(i) No party shall have any liability for any otherwise indemnifiable Loss to the extent the Vertical/Trigen Indemnitees have been otherwise compensated through the adjustment under Section 1.04; (ii) no party shall have any liability for an otherwise indemnifiable Loss that is contingent unless and until such contingent Loss becomes an actual Loss of the Indemnified Party and is due and payable, so long as the claim for such Loss was timely submitted pursuant to the provisions of this Article IX; (iii) no party shall be liable for any Losses to the extent the Vertical/Trigen Indemnitees or the Osmotica Indemnitees, as applicable, failed to reasonably mitigate such Losses in accordance with Laws; and (iv) no party shall be liable for any otherwise indemnifiable Loss arising out of any breach of any representation, warranty, covenant or agreement of such party unless a claim therefor is asserted with specificity and in writing by the Indemnified Party timely in accordance with Section 9.08, failing which such claim shall be waived and extinguished.

(d)For purposes of this Article IX, in determining the failure of any representations or warranties in Article III or Article IV to be true and correct or the breach thereof, and calculating Losses hereunder, any “materiality” or “Material Adverse Effect” qualifications in the

82

representations or warranties made hereunder shall be disregarded, other than (x) those set forth in Sections 3.03 (Non-Contravention and Approvals), 3.05 (Osmotica Financial Statements), 3.06 (No Undisclosed Liabilities), 3.07 (Absence of Changes)(including, for purposes of Section 3.07(c), as materiality is referenced in Section 5.01(a)), 3.16 (Compliance with Laws), Sections 4.03 (Non-Contravention and Approvals), 4.05 (Vertical/Trigen Financial Statements), 4.06 (No Undisclosed Liabilities), and 4.07 (Absence of Changes) (including, for purposes of Section 4.07(c), as materiality is referenced in Section 5.01(b)), 4.16 (Compliance with Laws), and (y) any qualification to the extent it qualifies a representation requiring a list of specified items on the Osmotica Disclosure Schedule or Vertical/Trigen Disclosure Schedule, as applicable.

SECTION 9.05.Calculation of Indemnity Payments.

(a)The amount of any Loss for which indemnification is provided under this Article IX shall be net of any amounts directly recovered or recoverable by the Indemnified Party (including under insurance policies) with respect to such Loss.

(b)If an Indemnified Party directly recovers an amount from a third party in respect of Losses that are the subject of indemnification hereunder after all or a portion of such Losses have been paid by an Indemnifying Party pursuant to this Article IX, then the Indemnified Party shall promptly remit to the Indemnifying Party the excess (if any) of (i) (A) the amount paid by the Indemnifying Party in respect of such Losses plus (B) the amount received by the Indemnified Party in respect thereof over (ii) the full amount of the Losses. In the event that an Indemnified Party has any rights against a third party with respect to any Loss that results in a payment by an Indemnifying Party under this Article IX, such Indemnifying Party shall be subrogated to such rights to the extent of such payment. Without limiting the generality of any other provision hereof, each Indemnified Party shall duly execute upon request all instruments reasonably necessary to evidence and perfect the subrogation and subordination rights detailed herein, and otherwise cooperate in the prosecution of such claims.

(c)Each party shall, and shall cause its respective affiliates to, take all reasonable steps to mitigate any Loss indemnifiable hereunder upon and after becoming aware of any event that would reasonably be expected to give rise to any Loss. No party shall be entitled to any payment, adjustment or indemnification more than once with respect to the same matter.

SECTION 9.06.Exclusivity. From and after the Closing, the Vertical/Trigen Indemnitees’ and the Osmotica Indemnitees’ sole and exclusive remedies with respect to any and all claims relating to this Agreement or the Transactions shall be pursuant to the indemnification provisions set forth in this Article IX and the remedies in Section 11.15; provided, that nothing in this Agreement (other than, to the extent applicable, the applicable Excluded Claim Caps), including this Section 9.06, shall limit any remedy that any Vertical/Trigen Indemnitee or Osmotica Indemnitee may have against any person for any Losses arising out of or resulting from actual fraud by the Osmotica Shareholders or Osmotica with respect to any of their representations and warranties contained in Article III or by the Vertical/Trigen Shareholders or Vertical/Trigen with respect to any of their representations and warranties contained in Article IV, as the case may be.

83

SECTION 9.07.Tax Treatment of Indemnification. For all Tax purposes, the parties hereto agree to treat any indemnity payment under this Agreement as an adjustment to the consideration received hereunder unless a final determination of a Taxing Authority (which shall include the execution of an IRS Form 870-AD or successor form) provides otherwise.

SECTION 9.08.Survival. The representations and warranties contained in this Agreement shall survive the Closing solely for purposes of Sections 9.01 and 9.02 and shall terminate at 11:59 p.m. New York City time on May 31, 2017 (the period from the Closing Date to such date, the “Survival Period”); provided, that the Osmotica Fundamental Representations and the Vertical/Trigen Fundamental Representations shall survive until the close of business on the date that is 30 days after the expiration of the applicable statute of limitations. The covenants or agreements contained in this Agreement to be performed at or prior to the Closing shall survive the Closing for the Survival Period and those which by their terms contemplate performance after the Closing Date shall survive the Closing only until 30 days after the expiration of the term of the undertaking set forth in such agreements and covenants. Notwithstanding the first sentence of this Section 9.08, the indemnities contained in Sections 9.01(g), 9.01(h) and 9.02(f) shall survive the Closing until the close of business on May 31, 2019. After the Closing, no party shall have any liability or obligation of any nature with respect to any representation, warranty, agreement or covenant after the termination thereof unless a notice of a breach thereof giving rise to a right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time. Notwithstanding anything to the contrary in this Section 9.08, if notice of any claim for indemnification shall have been given with specificity and in writing to the party against whom such indemnity may be sought within the applicable survival period, the representations, warranties, covenants or agreements that are the subject of such indemnification claim shall survive with respect to such claim until such time as such claim is finally resolved.

SECTION 9.09.Settlement of Indemnification Obligations.

(a)Until the funds in the Osmotica Indemnification Escrow Account are reduced to zero (0), all indemnification payments to the Vertical/Trigen Indemnitees shall be made first out of the Osmotica Indemnification Escrow Account. Subject to the limitations set forth in Section 9.04 and in the Escrow Agreement, (i) any indemnification of the Vertical/Trigen Indemnitees for which the Osmotica Shareholders are liable pursuant to this Article IX shall be satisfied from the Osmotica Indemnification Escrow Account, by the release of cash from the Osmotica Indemnification Escrow Account by the Escrow Agent to the relevant Vertical/Trigen Indemnitee(s) in accordance with the Escrow Agreement, and (ii) with respect to any claims for indemnification of Losses on account of any Vertical/Trigen Excluded Claims, if funds in the Osmotica Indemnification Escrow Account are insufficient to satisfy all such Losses or if such indemnification obligation arises after the Escrow Termination Date or the 9.01(h) Resolution Date, as applicable, then the Osmotica Shareholders shall be liable, severally (according to their Osmotica Pro Rata Percentages) but not jointly, to the Vertical/Trigen Indemnitees for the amount of all such Losses not satisfied from the Osmotica Indemnification Escrow Account (“Osmotica Excess Losses”). The portion of any Osmotica Excess Losses for which any Osmotica Shareholder is liable pursuant to this Article IX shall be paid by such Osmotica Shareholder in cash, by wire transfer of immediately available funds, to the Vertical/Trigen Shareholders’ Representative (for distribution to the applicable Indemnified Parties) or to New HoldCo, as applicable, within five (5) Business Days of becoming due. In the event such payment is not timely received by the

84

Vertical/Trigen Shareholders’ Representative or New HoldCo, as applicable, (i) the Vertical/Trigen Shareholders’ Representative may elect, in its sole discretion, to instead cause New HoldCo to (and New HoldCo shall) pay any amounts otherwise distributable to the applicable Osmotica Shareholder instead to the Vertical/Trigen Shareholders’ Representative (for distribution to the applicable Indemnified Parties) or (ii) New HoldCo may elect, in its sole discretion, to instead set off any such amounts against amounts otherwise distributable to the applicable Osmotica Shareholder.

(b)[START]Until the funds in the Vertical/Trigen Indemnification Escrow Account are reduced to zero (0), all indemnification payments to the Osmotica Indemnitees shall be made first out of the Vertical/Trigen Indemnification Escrow Account.

Subject to the first sentence of this Section 11.01, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any attempted assignment or transfer in violation of this Section 11.01 shall be null and void. For the avoidance of doubt, none of the Transactions and no other transaction expressly contemplated by this Agreement shall constitute an assignment requiring consent pursuant to this Section 11.01.

SECTION 11.02.No Third-Party Beneficiaries. Except as provided in this Section 11.02 or in Section 5.10, Article IX or Article X, this Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein expressed or implied shall give or be construed to give to any person, other than the parties hereto and such successors and assigns, any legal or equitable rights hereunder.

In the event the Closing does not occur and this Agreement is terminated, or to the extent such expenses exceed the limits set forth on Annex 2 and the Closing occurs, then, except as otherwise expressly set forth herein, each party shall bear its own fees and expenses. Prior to the Closing, the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative shall consider in good faith any additional expenses that any party reasonably requests to include on Annex 2, and the Osmotica Shareholders’ Representative, on the one hand, and the Vertical/Trigen Shareholders’ Representative, on the other hand, may mutually agree to modify Annex 2. If the Osmotica Shareholders’ Representative and the Vertical/Trigen Shareholders’ Representative agree in writing to a deviation from Annex 2 in accordance with this Section 11.03 (in which case the parties shall cause Annex 2 to be revised accordingly), then for purposes of this Agreement, all references to Annex 2 shall be deemed to be references to Annex 2 as so revised.

The parties acknowledge and agree that the Vertical/Trigen Shareholders’ Representative, on behalf of the Vertical/Trigen Shareholders, shall be entitled to an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction without proof of damages or otherwise, this being in addition to any other remedy to which it is entitled under this Agreement; provided, that the right of the Vertical/Trigen Shareholders’ Representative, on behalf of the Vertical/Trigen Shareholders, to any such injunction, specific performance or other equitable relief to consummate the Closing shall be subject to the requirements that all of the conditions to Closing set forth in Section 7.01 and 7.03 were satisfied or waived at the time when the Closing would have been required to occur pursuant to Section 1.01 (assuming for such purpose that all of the conditions set forth in Sections 7.01, 7.02 and 7.03 have been satisfied) and remain satisfied or waived (other than those conditions (1) which by their nature are intended to be satisfied at the Closing or (2) the failure of which to be satisfied is attributable primarily to a breach by the Osmotica Shareholders or Osmotica of their respective representations, warranties, covenants or agreements contained in this Agreement). In addition, the parties acknowledge and agree that, notwithstanding anything to the contrary in this Agreement, prior to the Closing the Osmotica Shareholders’ Representative, on behalf of the Osmotica Shareholders, shall only be entitled to an injunction, specific performance or other equitable remedies (i) to enforce the obligation of the applicable Vertical/Trigen Shareholders to cause their (and their affiliates’ to the extent such affiliates are not signatories hereto) respective portion of the Vertical/Trigen Cash Contribution to be funded or to cause the Vertical/Trigen Shareholders to consummate the Closing or (ii) in connection with enforcing Vertical/Trigen’s obligation to enforce the terms of the Commitment Letters, including any alternative financing that has been obtained in accordance with Section 5.12(a), in the case of each of clauses (i) and (i]), in any court of competent jurisdiction without proof of damages or otherwise; provided, that the right of the Osmotica Shareholders’ Representative, on behalf of the Osmotica Shareholders, to an injunction, specific

106

performance or other equitable remedies to enforce the obligation of the applicable Vertical/Trigen Shareholders to cause their (and their affiliates’ to the extent such affiliates are not signatories hereto) respective portion of the Vertical/Trigen Cash Contribution to be funded or to cause the Vertical/Trigen Shareholders to consummate the Closing shall be subject to the requirements that (i) all of the conditions to Closing set forth in Section 7.01 and 7.02 were satisfied or waived at the time when the Closing would have been required to occur pursuant to Section 1.01 (assuming for such purpose that all of the conditions set forth in Sections 7.01, 7.02 and 7.03 have been satisfied) and remain satisfied or waived (other than those conditions (1) which by their nature are intended to be satisfied at the Closing or (2) the failure of which to be satisfied is attributable primarily to a breach by the Vertical/Trigen Shareholders or Vertical/Trigen of their respective representations, warranties, covenants or agreements contained in this Agreement), (ii) the Financing has been funded in accordance with the terms thereof or all of the conditions to the consummation of the Financing (including any alternative financing that has been obtained in accordance with Section 5.12(a)) have been satisfied (or would be satisfied if the Vertical/Trigen Cash Contribution is funded at the Closing), (iii) each of the Osmotica Shareholders and New HoldCo has irrevocably confirmed in writing that if the Vertical/Trigen Cash Contribution and Financing are funded then it would consummate the Closing and (iv) the Vertical/Trigen Shareholders fail to consummate the Closing on the date when the Closing should have occurred pursuant to Section 1.01 (assuming for such purpose that all of the conditions set forth in Sections 7.01, 7.02 and 7.03 have been satisfied); and provided, further, that the right of the Osmotica Shareholders’ Representative, on behalf of the Osmotica Shareholders, to an injunction, specific performance or other equitable remedies in connection with enforcing Vertical/Trigen’s obligation to enforce the terms of the Commitment Letters, including any alternative financing that has been obtained in accordance with Section 5.12(a), shall be subject to the requirements that (i) all of the conditions set forth in Sections 7.01 and 7.02 have been satisfied (other than those conditions (1) which by their nature are intended to be satisfied at the Closing or (2) the failure of which to be satisfied is attributable primarily to a breach by the Vertical/Trigen Shareholders or Vertical/Trigen of their respective representations, warranties, covenants or agreements contained in this Agreement), and the Vertical/Trigen Shareholders fail to complete the Closing by the date the Closing is required to have occurred pursuant to Section 1.01 (assuming for such purpose that all of the conditions set forth in Sections 7.01, 7.02 and 7.03 have been satisfied), and (ii) all of the conditions to the consummation of the Financing (including any alternative financing that has been obtained in accordance with Section 5.12(a)) have been satisfied (or would be satisfied if the Vertical/Trigen Cash Contribution is funded at the Closing) (other than those conditions (1) which by their nature are intended to be satisfied at the Closing or (2) the failure of which to be satisfied is attributable primarily to a breach by the Vertical/Trigen Shareholders or Vertical/Trigen of their respective representations, warranties, covenants or agreements contained in this Agreement). Notwithstanding anything to the contrary in this Agreement, and for purposes of clarity, except as expressly provided for in the immediately preceding sentence of this Section 11.15, the parties acknowledge and agree that the Osmotica Shareholders’ Representative, Osmotica and the Osmotica Shareholders shall not be entitled to an injunction or injunctions to prevent breaches of this Agreement by the Vertical/Trigen Shareholders (other than in respect of their obligations to cause the Vertical/Trigen Cash Contribution to be funded if the provisions of the immediately preceding sentence of this Section 11.15 have been satisfied) or to enforce specifically the terms and provisions of this Agreement at any time prior to or at the Closing and that the sole and exclusive remedy of the Osmotica Shareholders’ Representative, Osmotica and the Osmotica

107

Shareholders with respect to any such breach shall be monetary damages (such damages, for the avoidance of doubt, shall not be limited in amount pursuant to the terms of this Agreement including Section 9.04). The right of specific enforcement under this Section 11.15 is an integral part of the Transactions and without that right, none of the parties hereto would have entered into this Agreement. Accordingly, the parties hereto agree not to assert that a remedy of specific enforcement consistent and in accordance with this Section 11.15 is unenforceable, invalid, contrary to Law or inequitable for any reason, and not to assert that a remedy of monetary damages would provide an adequate remedy or that the parties otherwise have an adequate remedy at Law. The parties hereto acknowledge and agree that any party seeking an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 11.15 shall not be required to provide any bond or other security in connection with any such order or injunction. If a court rules that any of the Vertical/Trigen Shareholders or Vertical/Trigen breached its obligations under this Agreement in connection with its failure to effect the Closing in accordance with Section 1.01, but declines to cause Vertical/Trigen or its affiliates to enforce the terms of the Commitment Letters, including any alternative financing that has been obtained in accordance with Section 5.12(a), or to effect the Closing in accordance with Section 1.01, on the terms and subject to the conditions in this Agreement, pursuant to a claim for specific performance brought against the Vertical/Trigen Shareholders or Vertical/Trigen pursuant to, and in accordance with, this Section 11.15, then, in addition to the right of the Osmotica Shareholders’ Representative to terminate this Agreement pursuant to Section 8.01(d)(ii) and collect the Termination Fee, the Osmotica Shareholders and Osmotica shall have the right to be paid all costs and expenses (including attorneys’ fees) incurred by them and their respective affiliates in connection with all actions to seek specific performance of the obligations of the Vertical/Trigen Shareholders and Vertical/Trigen pursuant to this Agreement and the Commitment Letters and all actions to collect such fee or expenses. For the avoidance of doubt, in no event shall the exercise of the right of the Osmotica Shareholders’ Representative to seek specific performance pursuant to this Section 11.15 reduce, restrict or otherwise limit the Osmotica Shareholders’ Representative’s right to terminate this Agreement pursuant to Section 8.01(d)(ii) and be paid the Termination Fee. Notwithstanding anything in this Agreement to the contrary, prior to the Closing, (x) only the Osmotica Shareholders’ Representative shall have the right to specifically enforce or obtain other equitable relief with respect to the obligations of Vertical/Trigen or the Vertical/Trigen Shareholders under the third sentence of this Section 11.15, and (y) only the Vertical/Trigen Shareholders’ Representative shall have the right to specifically enforce or obtain other equitable relief with respect to the obligations of Osmotica or the Osmotica Shareholders under the second sentence of this Section 11.15.

SECTION 11.16.Joint Drafting. The parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Agreement.

SECTION 11.17.Fulfillment of Obligations. Any obligation of any party to any other party under this Agreement or any of the Ancillary Agreements, which obligation is performed, satisfied or fulfilled completely by an affiliate of such party, shall be deemed to have been performed, satisfied or fulfilled by such party.

108
