Fifty Four and No/100 Dollars ($2,092,054.00)(the “Second Note” and together with the First Note, the “Notes”). 
 The parties acknowledge and agree that the Purchase Price may be adjusted pursuant to Section 3.2 below. 
  

 11 








 Section 3.2 Working Capital Adjustment. 
 (a) On or before the Closing Date, the Seller shall deliver to the Purchaser a statement of Working Capital (including the related notes and
schedules thereto) as of the close of business on the Closing Date, which shall set forth the estimated Working Capital and shall set forth in detail the amounts underlying such calculation. The statement of estimated Working Capital shall be
consistent in such respects with the model calculation set forth on Schedule 3.2(a). In the event that the Seller and the Purchaser disagree over the statement of estimated Working Capital or the amount of the estimated Working
Capital, the estimated Working Capital prepared by Seller shall be deemed to be the estimated Working Capital for purposes of Closing. If the Working Capital as shown in the Final WC Statement is less than Two Million Two Hundred Fifty Thousand
and 00/100 Dollars ($2,250,000.00) (the “WC Benchmark”), the parties acknowledge that the principal amount of the Notes may be adjusted in accordance with the balance of this Section 3.2 (the “Working Capital
Adjustment”). 
 (b) As promptly as practicable, but no later than 45 calendar days after the Closing Date, the Purchaser shall
prepare and deliver to the Seller a statement of Working Capital (including the related notes and schedules thereto) as of the close of business on the Closing Date, which shall set forth the Purchaser’s determination of the Working Capital and
shall set forth in detail the amounts underlying such calculation (the “Initial WC Statement”). The calculation of the Working Capital set forth on the Initial WC Statement will be prepared in accordance with GAAP and, for
purposes of clarity, shall be consistent with the model calculation set forth on Schedule 3.2(b) which is included for illustrative purposes only. During the 15 calendar days immediately following the Seller’s receipt of the
Initial WC Statement, the Seller and its representatives will be permitted during business hours in a manner which will not unreasonably interfere with the operation of the Business to review at the Purchaser’s offices the Purchaser’s
working papers (including work papers of accountants and other advisors) relating to the Initial WC Statement, as well as all of the books and records relating to the operations and finances of the Business with respect to the period up to and
including the Closing Date, and the Purchaser shall make reasonably available at its offices the individuals responsible for the preparation of the Initial WC Statement in order to respond to the reasonable inquiries of the Seller related thereto.

 (c) The Seller shall notify the Purchaser in writing (the “Notice of Disagreement”) within 20 calendar days after
receiving the Initial WC Statement if the Seller disagrees with the Purchaser’s calculation of the Working Capital, which Notice of Disagreement shall set forth in reasonable detail the basis for such dispute and the U.S. Dollar amounts
involved and the Seller’s good faith estimate of the Working Capital. Any item not specifically disputed by the Seller shall be deemed accepted by the Seller and shall become part of the Final WC Statement. If the Seller does not
deliver a Notice of Disagreement to the Purchaser within such 20 calendar day period, then the Initial WC Statement shall be deemed to have been accepted by the Seller, shall become final and binding upon the parties and shall be the Final WC
Statement. 
  

 12 








 (d) During the 30 calendar day period immediately following the delivery of a Notice of
Disagreement, the Seller and Purchaser shall seek in good faith to resolve any differences that they may have with respect to any matter specified in the Notice of Disagreement. If at the end of such 30 calendar day period the Seller and
Purchaser have been unable to agree upon a Final WC Statement, then the Seller and Purchaser shall submit to a mutually agreeable independent accounting firm (the “Independent Accounting Firm”) for review and resolution any
and all matters that remain in dispute with respect to the Notice of Disagreement. The Seller and Purchaser shall cause the Independent Accounting Firm to use commercially reasonable efforts to make a final determination (which determination
shall be binding on the parties hereto) of the Working Capital within 30 calendar days from such submission, and such final determination shall be the Final WC Statement. The cost of the Independent Accounting Firm’s review and
determination shall be split between and paid by the Seller and Purchaser on a proportionate basis, based upon the relative amount by which the determination of the Working Capital of each of them differed from that determined by the Independent
Accounting Firm. During the 30 calendar day review by the Independent Accounting Firm, the Seller and Purchaser will each make available to the Independent Accounting Firm such individuals and such information, books and records as may be
reasonably required by the Independent Accounting Firm to make its final determination. 
 (e) If the Working Capital (as set forth in
the Final WC Statement) is less than the WC Benchmark, then the principal amount of the Notes shall be reduced by an amount equal to such shortfall. 
 (f) In furtherance of the calculation of the Working Capital, on the Business Day immediately preceding the Closing Date, the parties and such parties’ representatives and agents may conduct a physical
inventory of all tangible property forming a part of the Purchased Assets in a manner consistent with Seller’s past practice. 
 Section 3.3 Additional Earnout Consideration. In addition to the Purchase Price, Purchaser shall pay to Seller the following amounts: 
 (a) Net Sales Earnout. Provided Purchaser and its Affiliates have Net Sales of Active Products in excess of $10,000,000.00 during
each applicable twelve (12) month period, Purchaser shall pay Seller an amount equal to seven percent (7%) of such Net Sales with respect to the Active Products on a quarterly basis for three (3) successive twelve (12) month
periods following the Closing Date for a total of thirty-six (36) months, beginning with the quarter beginning on March 1, 2009 and ending on February 28, 2012 (the “Earnout Period”). No such quarterly payments shall be due
and payable until Purchaser and its Affiliates have Net Sales of Active Products for the applicable 12 month period exceed $10,000,000, at which time the payments with respect to any preceding quarter(s) shall be included in the payment made
with respect to the quarter in which such threshold was exceeded. In the event there is an interruption in supply from the manufacturer of any of the Active Products resulting in a back-order of more than 45 days during the first two hundred
forty (240) days after the Closing Date for one or more of the specific Active Products, all sales of the specific Active Product(s) subject to such back-order shall be excluded in calculating any payment to Seller under this
Section 3.3(a) for the first twelve (12) month period (although such sales shall be included in determining whether the $10,000,000 net sales threshold has been met). For the purposes of this Section, “back-order” shall mean
a purchase order from a customer which has not been fulfilled within 45 days after the delivery date stated in such purchase order. In the event any regulatory action prohibits the sale or shipment of the Active Products Lodrane 24, Lodrane 24D
or Lodrane 12D subject to any grace or other period during which Purchaser and its Affiliates can continue to sell or ship such Active Products, the payment obligations herein shall continue in full force during such grace or other period and
the sales of such Active Products shall be included in Net Sales in calculating any payments due hereunder. The total amount payable by Purchaser to Seller and Caskey for any twelve (12) month period shall not exceed One Million Six Hundred
Eighty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,683,333.33). 
  

 13 








 (b) Gross Profit Earnout. To the extent Purchaser and its Affiliates have a Gross Profit
with respect to the Active Products in any of the three (3), successive twelve (12) month periods in the Earnout Period exceeds Nine Million and No/100 Dollars ($9,000,000.00), Purchaser shall make an additional payment to Seller, as
follows: (i) if Purchaser and its Affiliates have a Gross Profit with respect to the Active Products in any such twelve (12) month period of greater than Nine Million and No/100 Dollars ($9,000,000.00), but less than Eleven Million
and No/100 Dollars ($11,000,000.00), Purchaser shall pay Seller and Caskey the sum of Five Hundred Forty One Thousand Six Hundred Sixty Seven and No/100 Dollars ($541,667.00); or (ii) if Purchaser and its Affiliates have a Gross
Profit with respect to the Active Products in any such twelve (12) month period of Eleven Million and No/100 Dollars ($11,000,000.00) or more, Purchaser shall pay to Seller and Caskey the sum of Eight Hundred Thirty Three Thousand Three Hundred
Thirty Three and No/100 Dollars ($833,333.00). 
 (c) Aggregate Earnout Limitation. In no event shall Purchaser be
required to pay Seller and Caskey an amount in excess of Four Million and No/100 Dollars ($4,000,000.00) pursuant to Sections 3.3 (a) and 3.3 (b) collectively. 
 (d) Reports and Payments. In connection with the contingent payments described in Section 3.3, Purchaser agrees to provide Seller with (i) quarterly reports indicating Purchaser’s and
its Affiliates’ Net Sales with respect to the Active Products for such quarter together with the payment required under Section 3.3(a) with respect thereto, within forty-five (45) days of the end of the applicable quarter; and
(ii) annual reports, certified by Purchaser’s Chief Financial Officer, indicating Purchaser’s and its Affiliates’ Gross Profit and Net Sales with respect to the Active Products for each twelve (12) month period, and
supporting documents therefor, along with the payment required under Section 3.3(b) with respect thereto, within sixty (60) days of the end of the applicable twelve (12) month period. In addition to the foregoing, Purchaser shall
provide Seller and Caskey with audited annual reports showing Purchaser’s and its Affiliates’ Net Sales and Gross Profit for each fiscal year during which any payments hereunder are due, which audited annual reports shall be delivered
within ninety (90) days of the end of each such fiscal year. 
 (e) Inspection Right. Upon prior written notice and at
mutually agreeable times, Seller and Caskey shall have the right to inspect Purchaser’s financial records and information, solely for the purpose of auditing the reports referred to in Section 3.4 with respect to the calculation of the
contingent payments referred to in Section 3.3 hereof, once during each of the four (4) twelve (12) month periods following the Closing Date. 
  

 14 








 (f) Disagreement. If the Seller and Purchaser disagree on the amount of Gross Profit or
Net Sales with respect to the Active Products for any period, and the variance between Purchaser’s and the other Seller’s determination of such number is in excess of Ten Thousand and No/100 Dollars ($10,000.00), then Seller and Purchaser
shall engage the Independent Accounting Firm, or such other independent accountant firm as may be selected by the Parties, to determine the Gross Profit or Net Sales with respect to the Active Products, as the case may be, for each
period in dispute, and such amount shall be binding on the Seller and Purchaser. Purchaser and Seller shall each bear fifty percent (50%) of the costs of engaging such third party. In the event it is determined that Purchaser owes any
additional amounts to Seller or Seller owes any refund to Purchaser to in connection with any dispute, such amount shall be paid by such Party within fifteen (15) days of the date on which such dispute is resolved. Furthermore, and
notwithstanding anything herein to the contrary, in the event it is determined or agreed that any underpayment by Purchaser to Seller with respect to the contingent payments provided for in Section 3.3 is 10% or more of the amount actually owed
to Seller, Purchaser shall (i) be solely responsible for the costs of engaging a third-party as described above, and (ii) pay to Seller interest on the amount of any shortfall at a rate of 10% per annum. 
 (g) Sale of Business. If after the Closing Date but before the expiration of the Earnout Period, Purchaser and its Affiliates shall sell
all or substantially all of the Business to a third-party, (i) Purchaser and its Affiliates shall cause such third-party purchaser to assume Purchaser’s remaining obligations under Section 3.3 in accordance with their terms and
(ii) Purchaser shall remain liable for such obligations. In the alternative, in connection with such a sale Purchaser may pay to Seller an amount equal to $4,000,000, minus the aggregate amount already paid by the Purchaser to the
Seller under Section 3.3(a) or Section 3.3(b). 
 (h) Sale of a Product. If after the Closing Date but before the
expiration of the Earnout Period, Purchaser and its Affiliates shall sell all of the assets related to one or more Products, but not the entire Business, to a third-party purchaser, the parties agree that the sales of such Product or Products by
such third-party purchaser shall continue to be included in the Net Sales of the Purchaser and its Affiliates for the purposes of calculating the Net Sales Earnout under Section 3.3(a) and the Gross Profit Earnout under Section 3.3(b),
except as otherwise agreed in writing by the Seller. 
 Section 3.4 Allocation of Purchase Price (Seller and
Caskey). Any and all amounts to be paid under Section 3.1(a) and Section 3.3 and any adjustments with respect thereto shall be allocated between Seller and Caskey as set forth on Schedule 3.4 attached hereto. In
addition, the amount payable under the Notes pursuant to Section 3.1(b) shall be allocated between Caskey and Seller in accordance with such Schedule 3.4. 
 Section 3.5 Payment of Purchase Price. That portion of the Purchase Price described in Section 3.1(a) shall be paid by Purchaser to the Representative (as defined in Section 7.8(g)) on
the Closing Date in immediately available funds and by wire transfer, pursuant to wiring instructions provided by the Representative to Purchaser not less than three (3) Business Days prior to the Closing Date. That portion of the Purchase
Price described in Section 3.3 shall be paid by Purchaser to the Representative in immediately available funds and by wire transfer, pursuant to the wiring instructions provided to Purchaser. Such payments shall, together with the payments
under the Notes described in Section 3.1(b), satisfy Purchaser’s obligation to Caskey, and Caskey shall look solely to the Representative for his share of such payments as set forth on Schedule 3.4. 
  

 15 








 Section 3.6 Payment of Sales, Use and Other Taxes. Seller shall be responsible
for all sales, use, stamp duty, transfer, value added and other related or similar Taxes, if any, arising out of the sale by Seller and Caskey of the Purchased Assets to Purchaser pursuant to this Agreement or payable in connection with the
Contemplated Transactions. 
 Section 3.7 Prorations. The Parties acknowledge that there will be expenses paid or
payable either before or after the Closing Date which relate to a period of time which spans the Closing Date, thus partly attributable to Seller and partly attributable to Purchaser. The part attributable to Seller will be calculated as the
number of calendar days in the period in question prior to and including the Closing Date, divided by the total number of calendar days in the period in question. The part attributable to Purchaser will be calculated as the number of calendar
days after the Closing Date divided by the total number of calendar days in question. Any such expenses paid or payable prior to the Closing Date may be included in Prepaid Expenses. Purchaser shall process all such expenses paid after
closing and shall deliver to Seller on a monthly basis an invoice for the Seller’s share, together with documentation evidencing such items, and Seller shall remit payment for such amounts within thirty (30) days from the date of such
invoices. The expenses referenced above may include, but are not limited to: rent, common area maintenance charges, utilities, employee benefits (medical, dental, life insurance, health savings account, employer 401k match), employee expense
reimbursement, insurance, payroll and payroll taxes, wholesale audit reports, computer maintenance, contracted services fees, Taxes and licenses, and dues and subscriptions. Notwithstanding anything set forth herein to the contrary, Seller
shall be solely responsible for any expenses that relate just to the month in which the Closing Date occurs.

clear of all Encumbrances, and are legally entitled to transfer the Intellectual Property, or the right to use the Intellectual Property, to Purchaser. Each item of Intellectual Property owned or used by Seller or Caskey will be available for
use by the Purchaser on identical terms and conditions immediately following the Closing Date. The Intellectual Property constitutes all of such property reasonably necessary for the operation of the Business as presently conducted.

 (b) To Seller’s and Caskey’s knowledge, none of the Intellectual Property, the use of Intellectual Property or the

present or continued use of any of the Intellectual Property or Products infringes, violates, misappropriates or otherwise interferes with the rights of any Person. No inventions that comprise part of the Intellectual Property are subject to a
pending patent application or a patent registration, either by Seller, Caskey, or any other third party.

reliance on the special knowledge or memory of others, and all such writings have been provided to Purchaser. 
 (f) Seller and Caskey
have made no previous assignment, transfer or agreement constituting a present or future interest in or assignment or transfer of any of the Intellectual Property. Seller and Caskey have granted no release, covenant not to sue, or non-assertion
assurance to any Person with respect to any part of the Intellectual Property. There are no agreements that restrict or limit the use by Seller, Caskey, or Purchaser, of the Intellectual Property. No intellectual property other than the

stored or Released by any of the Seller or any other Person (including third parties) on, under, about or from any of the Purchased Assets, the Leased Real Property or otherwise, in connection with the Business. 
  

 23 








 (c) Neither Seller, the Purchased Assets, nor any Leased Real Property is subject to any outstanding
order from, or contractual or other obligation with, any third party in respect of which Seller or Purchaser may be required to incur costs arising from the Release or threatened Release of Hazardous Materials. Seller has not entered into any
contractual or indemnification obligation with any third party pursuant to which it assumed responsibility for, either directly or indirectly, the remediation of any condition arising from or relating to the Release or threatened Release of
Hazardous Materials. 
 Section 4.25 Insurance. Seller has delivered to Purchaser complete and correct copies of all
insurance policies maintained (at present or any time during the past three (3) years) by or on behalf of Seller or relating to the Business or the Purchased Assets, together with all riders and amendments thereto and a description of all
insurance claims made by the Seller during the three (3) years preceding the date of this Agreement. Set forth on Schedule 4.25 is a list of all the insurance policies in effect as of the date hereof. Such policies are in full
force and effect, and all premiums due therein have been paid. Seller has complied in all respects with the terms and provisions of such policies applicable to it. No notice of termination or premium increase has been received under any of
the policies. Seller is not in breach or default, and no event has occurred that, with notice or the lapse of time, would constitute such a breach or default or permit termination, modification or acceleration under such policy. 
 Section 4.26 Employee Benefit Plans. For purposes of this Section 4.26, the term “Seller” includes any
ERISA Affiliate.
 (a) Schedule 4.26 contains an accurate and complete list of all Employee Benefit Plans. Accurate and
complete copies of all the following documents with respect to each Employee Benefit Plan, to the extent applicable, have been delivered to Purchaser: (i) all documents constituting the Employee Benefit Plan, including trust agreements,
insurance policies, service agreements, and formal and informal amendments thereto; (ii) the three most recently filed Forms 5500 or 5500C/R and any financial statements attached thereto; (iii) all Internal Revenue Service
(“IRS”) determination letters for the Employee Benefit Plan; (iv) the most recent summary plan description and any amendments or modifications thereof; (v) all reports submitted within the preceding three years by
third-party administrators, actuaries, investment managers, consultants, or other independent contractors; (vi) all notices that were issued within the preceding three years by the IRS, Department of Labor, or any other Governmental or
Regulatory Authority with respect to the Employee Benefit Plan; (vii) written descriptions of all non-written Contracts relating to each Employee Benefit Plan; (viii) all memoranda, minutes, resolutions and similar documents describing the
manner in which the Employee Benefit Plan is or has been administered or describing corrections to the administration of an Employee Benefit Plan; and (ix) all employee manuals or handbooks containing personnel or employee relations policies.

 (b) Seller does not have any Liability to any benefit plan or arrangement other than the Employee Benefit Plans listed on Schedule
4.26 nor has Seller proposed any employee benefit plans or arrangements which it plans to establish or maintain or to which it plans to contribute or proposed any changes to any Employee Benefit Plans now in effect. No statement, either
written or oral, has been made by Seller to any Person with regard to any Employee Benefit Plan that was not in accordance with the Employee Benefit Plan and that could have an adverse economic consequence to Seller. 
  

 24 








 (c) Seller has properly submitted all of the Employee Benefit Plans intended to be qualified under
Section 401(a) of the Code, to the IRS for its approval within the time prescribed therefor under applicable federal regulations. Each of the Employee Benefit Plans intended to be qualified under section 401(a) of the Code has been
determined by the IRS to be qualified under section 401(a) of the Code and exempt from tax under section 501(a) of the Code, and each such determination remains in effect and has not been revoked. Other than the Employee Benefit Plans marked as
“Qualified Plans” on Schedule 4.26, no Seller has ever maintained or contributed to any other Employee Benefit Plan that is intended to be qualified under section 401(a) of the Code. Nothing has occurred with respect to
the design or operation of any Employee Benefit Plan that could cause the loss of such qualification or exemption or the imposition of any liability, lien, penalty, or tax under ERISA or the Code, and the Employee Benefit Plans have been timely
amended to comply with current Law. 
 (d) With respect to the Employee Benefit Plans, Seller will have made, on or before the Closing
Date, all payments required to be made by them on or before the Closing Date and will have accrued (in accordance with GAAP) as of the Closing Date all payments due but not yet payable as of the Closing Date, so there will not have been, nor will
there be, any Accumulated Funding Deficiencies (as defined in ERISA or the Code) or waivers of such deficiencies. All monies withheld from employee paychecks with respect to Employee Benefit Plans have been transferred to the appropriate
Employee Benefit Plan in a timely manner as required by applicable Law. 
 (e) All of the Employee Benefit Plans conform (and have at
all times conformed) to the requirements of ERISA, the Code and any other applicable Laws. Each Employee Benefit Plan has been maintained in accordance with its documents and with all applicable provisions of the Code, ERISA and any other
applicable Laws, including federal and state securities Laws. All reporting, disclosure and notice requirements of ERISA, the Code and other applicable Laws have been fully and completely satisfied with respect to each Employee Benefit Plan.

 (f) With respect to each Employee Benefit Plan, there has occurred no non-exempt “prohibited transaction” (within the
meaning of Section 4975 of the Code or Section 406 of ERISA) or breach of any fiduciary duty described in Section 404 of ERISA that could, if successful, result in any Liability, direct or indirect, for any Seller or any stockholder,
member, officer, director, manager or employee of Seller. 
 (g) Seller does not sponsor, maintain or contribute to, nor has Seller ever
sponsored, maintained or contributed to, or had any Liability with respect to, any employee benefit plan subject to Section 302 of ERISA, Section 412 of the Code or Title IV of ERISA. None of the Employee Benefit Plans is a
multiemployer plan (as defined in Section 3(37) of ERISA). Seller does not contribute to, nor has Seller ever contributed to or had any other Liability with respect to, a multiemployer plan. No Employee Benefit Plan is a
“multiemployer plan” within the meaning of Section 413 of the Code. Seller does not have any plan administration responsibilities, Liabilities or fiduciary responsibilities or duties with respect to any benefit plan which is
maintained by an employer that is not an ERISA Affiliate. 
  

 25 








 (h) Neither the execution and delivery of this Agreement or any of the other Transaction Documents
nor the consummation of the Contemplated Transactions will (i) result in any payment (including any severance, unemployment compensation or golden parachute payment) becoming due from Seller under any of the Employee Benefit Plans,
(ii) increase any benefits otherwise payable under any of Seller’s Benefit Plans, (iii) result in the acceleration of the time of payment or vesting of any such benefits to any extent, or (iv) result in any payments or
benefits under any Employee Benefit Plan or other agreement of Seller to be considered “excess parachute payments” under Section 280G of the Code. No payments or benefits under any Employee Benefit Plan or other agreement of
Seller are, or are expected to be, subject to the disallowance of a deduction under Section 162(m) of the Code. 
 (i) Seller has
not incurred any Liability for any excise, income or other taxes or penalties with respect to any Employee Benefit Plan, and no event has occurred and no circumstance exists or has existed that could give rise to any Liability. There are no
pending Actions or Proceedings that have been asserted or instituted against any of the Employee Benefit Plans, the assets of any of the trusts under such plans, the plan sponsor, the plan administrator or any fiduciary of any such plan (other than
routine benefit claims), and there are no facts which could form the basis for any such Action or Proceeding. There are no investigations, audits or examinations (nor has notice been received of a potential audit or examination) of any of
the Employee Benefit Plans, any trusts under such plans, the plan sponsor, the plan administrator or any fiduciary of any such plan that have been instituted or threatened by the IRS, Department of Labor or any other Government or Regulatory
Authority, and there are no facts which could form the basis for any such investigation, audit or examination, and no matters are pending with respect to any Employee Benefit Plan under any IRS correction program. 
 (j) With respect to any Employee Benefit Plan that is an employee welfare benefit plan (within the meaning of Section 3(1) of ERISA):
(i) each such plan for which contributions are claimed as deductions under any provision of the Code is in compliance with all applicable requirements pertaining to such deduction; (ii) with respect to any welfare benefit fund (within the
meaning of Section 4976(b) of the Code) that would result in the imposition of a Tax under Section 4976(a) of the Code; and (iii) any Employee Benefit Plan that is a group health plan (within the meaning of Section 4980B(g)(2) of
the Code) complies, and in each and every case has complied, with all of the requirements of Section 4980B of the Code, ERISA, Title XXII of the Public Health Service Act, the applicable provisions of the Social Security Act, the Health
Insurance Portability and Accountability Act of 1996, and other applicable Laws, and no Employee Benefit Plan provides health or other benefits after an employee’s or former employee’s retirement or other termination of employment except
as required by Section 4980B of the Code. 
 (k) Seller does not maintain, and does not have any obligation to contribute to or has
any Liability with respect to, any benefit plan or arrangement outside the U.S., nor has Seller ever had any Liability or liability with respect to any such benefit plan or arrangement. 
  

 26 








 Section 4.27 Section 409A of the Code. The Seller has not, since October 3,
2004, (i) granted to any person an interest in a nonqualified deferred compensation plan (as defined in Section 409A(d)(1) of the Code) which interest has been or upon the lapse of a substantial risk of forfeiture with respect to such
interest, will be subject to the tax imposed by Sections 409A(a)(1)(B) or (b)(4) of the Code, or (ii) modified the terms of any nonqualified deferred compensation plan (or failed to timely amend the terms of any nonqualified deferred
compensation plan) in a manner that could cause an interest previously granted under such plan to become subject to the tax imposed by Sections 409A(a)(1)(B) or (b)(4) of the Code. 
 Section 4.28 Survival of Representations and Warranties. The representations, warranties and agreements of Seller and Caskey set
forth in this Agreement are made as of the date of this Agreement and shall be true, correct, complete and accurate on and as of the Closing Date and at all times between the date of this Agreement and the Closing Date. The representations and
warranties of Seller and Caskey set forth in this Agreement shall survive the Closing.

Assets. Seller agrees that it will use its reasonable efforts to assist Purchaser in obtaining any required Permits and Medicaid state rebate agreements not currently held by Purchaser. Until such Permits and agreements are obtained, Seller
shall sub-contract with Purchaser or otherwise act in connection with such Permits and agreements in such respects as Purchaser may from time to time reasonably request in order to enable Purchaser to conduct the Business until it obtains such
Permits and agreements. Seller shall maintain any of its Permits and Medicaid state agreements that are subject to this provision until at least the earlier of (a) the date Purchaser obtains such Permit or agreement or (b) the date

 Section 7.8 Indemnification. 
 (a) By Seller. Seller shall indemnify, reimburse, and hold harmless Purchaser, its Affiliates, and their respective officers,
managers, directors, employees, agents, successors and assigns from and against any and all costs, losses, Liabilities, damages, pending, threatened or concluded lawsuits, deficiencies, claims and expenses (including reasonable fees and
disbursements of attorneys) (collectively, the “Damages”) to the extent such Damages are incurred in connection with or arise out of (i) any breach of any covenant or agreement of Seller or Caskey herein (including, but not
limited to, Section 6.1); (ii) the breach of any representation or warranty made by Seller or Caskey in this Agreement in each case without giving effect to any limitation in such representation or warranty based upon knowledge
of the Seller or Caskey (except as so qualified in Sections 4.5(b)(ii), 4.5(d), 4.5(e), 4.14, 4.22 and 4.23(f)), the absence of a material adverse effect or any other materiality qualification; and (iii) Liabilities related to the Products or
Purchased Assets arising out of the operation of the Business prior to the Closing Date (excluding the Assumed Liabilities). 
 (b) By Purchaser. Purchaser shall indemnify, reimburse, and hold harmless Caskey, Seller, its Affiliates and their respective officers, directors, employees, agents, successors and assigns from and against any and all Damages to
the extent such Damages are incurred in connection with or arise out of (i) any breach of any covenant or agreement of Purchaser herein; (ii) the breach of any representation or warranty made by Purchaser in this Agreement; and
(iii) any Assumed Liabilities; and (iv) the ownership or use of the Products and the other Purchased Assets following the Closing Date. 
 (c) Damages Net of Insurance. The failure of any Purchaser indemnified party to seek available insurance coverage or insurance proceeds for any Damages otherwise reimbursable by Section 7.8 shall not adversely affect
such Purchaser indemnified party’s rights to indemnification in respect thereof under Section 7.8. If, however, the Purchaser indemnified party receives insurance proceeds in respect of any such Damages, the amount of such insurance
proceeds less any associated costs, including reasonable attorney fees, incurred in obtaining such proceeds, shall be excluded in determining the amount of Damages subject to an indemnification claim. 
 (d) Limitations. No Party will have Liability (for indemnification or otherwise) with respect to claims of breach of any representation,
warranty or covenant, contained in this Agreement unless (i) on or before the date that is eighteen (18) months following the Closing Date (with respect to breaches of representations or warranties set forth in Article IV with respect to
Seller and Caskey or breaches of representations or warranties set forth in Article V with respect to Purchaser) or (ii) on or before the expiration of the applicable statute of limitations (with respect to breaches of any other agreement or
covenant contained in this Agreement), the otherwise liable Party is notified by the other Party of a claim specifying the factual basis of that claim in reasonable detail to the extent then known. In addition, and notwithstanding anything
set forth herein to the contrary, no Party shall be entitled to make a claim for indemnification or any other claim with respect to, or in connection with, a breach of a representation or warranty under Article IV or V unless and until all of
such Party’s claims for indemnifications or other claims with respect thereto total $50,000 in the aggregate (the “Threshold Amount”), following which such Party shall be entitled to recover all indemnified amounts in excess of
the Threshold Amount. In addition, in no event shall a Party’s liability for indemnification claims or other claims with respect to, or in connection with, a breach of a representation or warranty under Article IV or V exceed $2,000,000 in
the aggregate for claims asserted within twelve months after the Closing. Such amount shall be reduced to $1,000,000 for claims asserted thereafter and shall be further reduced by the amount of claims asserted within twelve months after the
Closing. 
  

 31 








 (e) Procedure for Indemnification – Third Party Claims. Promptly after receipt by
an indemnified party under Section 7.8(a) or 7.8(b) of notice of commencement of any proceeding against it by a third party (not a Party or Affiliate of a Party) to this Agreement, such indemnified party will, if a claim is to be made against
an indemnifying party under such Section, give notice to the indemnifying party of the commencement of such claim. If the indemnified party fails to notify the indemnifying party within thirty (30) days of receipt of notice of the third
party claim, then the indemnity with respect to the subject matter of such claim shall continue, but shall be limited to the damages that would have nonetheless resulted absent the indemnified party’s failure to notify the indemnifying party in
the time required above after taking into account such actions as could have been taken by the indemnifying party had it received timely notice from the indemnified party. If such notice is timely given, the indemnifying party will be entitled to
participate in such proceeding and, to the extent that it wishes, may assume the defense of such proceeding with counsel satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to
assume the defense of such proceeding with counsel satisfactory to the indemnified party, the indemnifying party will not be liable to the indemnified party under this Article VII for any fees of other counsel or any other expenses with respect to
the defense of such proceeding incurred after such notice. If the indemnifying party assumes the defense of the proceeding, (1) it will be conclusively established that for purposes of this Agreement that the claims made in that proceeding
are within the scope of and subject to indemnification; and (2) no compromise or settlement of such claims may be effected by the indemnifying party without the indemnified party’s Consent unless (A) there is no finding or admission
of any violation of legal requirements or any violation of the rights of any Person and no effect on any other claims that may be made against the indemnified party, and (B) the sole relief provided is monetary damages that are paid in full by
the indemnifying party. If notice is given to an indemnifying party of the commencement of any proceeding and the indemnifying party does not, within thirty (30) days after the indemnified party’s notice is given, give notice to the
indemnified party of its election to assume the defense of such proceeding, the indemnifying party will be bound by any determination made in such proceeding or any compromise or settlement effected by the indemnified party, provided, however, that
the indemnifying party is otherwise obligated to indemnify the indemnified party pursuant to this Section 7.8. 
  

 32 








 (f) Procedure for Indemnification – Other Claims. A claim for indemnification for
any matter not involving a third-party claim may be asserted by notice to the Party from whom indemnification is sought. 
 (g) Representative. Caskey hereby initially appoints, as of the date of this Agreement, Seller (together with its permitted successors, the “Representative”), as his true and lawful agent and attorney-in-fact
to: (i) resolve any claims by Purchaser with respect to the indemnification obligation in Section 7.8(a); (ii) consent or agree to, negotiate, enter into settlements and compromises of, and agree to arbitration and comply with
orders of courts and awards of arbitrators with respect to such claims; (iii) assert, negotiate, enter into settlements and compromises of, and agree to arbitration and comply with orders of courts and awards of arbitrators with respect to, any
other claim by any Purchaser indemnified party against Seller or Caskey or by Seller or Caskey against Purchaser or any dispute between any Purchaser indemnified party and Seller or Caskey, in each case relating to this Agreement or the transactions
contemplated hereby or thereby; (iv) amend this Agreement or any other agreement referred to herein or contemplated hereby; and (v) take all actions necessary or appropriate in the judgment of the Representative for the accomplishment of
the foregoing, in each case without having to seek or obtain the consent of Caskey under any circumstance. Any and all claims and disputes between or among any Purchaser indemnified party, the Representative or Caskey relating to this
Agreement or the transactions contemplated hereby shall in the case of any claim or dispute asserted by or against or involving Caskey (other than any claim against or dispute with the Representative), be asserted or otherwise addressed solely by
the Representative on behalf of Caskey (and not by Caskey acting on its own behalf). 
 Section 7.9 Purchaser’s Right of
Offset. To the extent Purchaser makes a timely claim for indemnification pursuant to Section 7.8(a) which is uncontested by the Representative or is ultimately determined in favor of Purchaser, Purchaser shall be entitled to offset the
amount due to it with respect to such claim from any payments owed under the Notes or Section 3.3 of this Agreement. In the event of a claim for indemnification under Section 7.8(a) that is contested by the Representative,
Purchaser shall not have the right to offset the amount claimed unless and until such time as (i) the Purchaser and the Representative reach an agreement on such claim, or (ii) such claim is ultimately determined in favor of
Purchaser. Pending such agreement or resolution with respect to such claim, the Purchaser shall be entitled to deduct the amount of such claim from any payments owed under the Notes or Section 3.3 of this Agreement and deposit such amount
in escrow with an escrow agent mutually acceptable to Purchaser and Representative. If Purchaser and Representative do not agree on an escrow agent within five Business Days of such deduction, Purchaser shall be entitled to deposit such escrow
amount with a bank, trust company or savings and loan association which is organized under the laws of the United States or any state thereof having capital, surplus and undivided profits aggregating in excess of $100 million. Purchaser,
Representative and any such escrow agent shall enter into an escrow agreement substantially in the form of Exhibit 7.9. In the event the payments to Seller under the Notes and Section 3.3 are insufficient to cover any such claim,
Seller and Caskey shall deliver the balance of the amount due in immediately available funds by wire transfer to an account designated by Purchaser. 
  

 33 








 Section 7.10 Governmental Filings. Each Party will prepare and file whatever
filings, requests or applications that are required to be filed with any Governmental or Regulatory Authority in connection with the consummation of the Contemplated Transactions. Each Party will provide the other a reasonable opportunity to
review and comment upon any such filings, requests or applications prior to filing. 
 Section 7.11 Employees. Purchaser covenants to provide employment as of the Closing Date to all Employees, excluding E. Claiborne Robins, Jr., with compensation and benefits that are substantially similar to those in
effect immediately prior to the Closing Date. Purchaser currently contemplates employing such Employees for an indefinite period and covenants not to terminate any such Employee so employed for a period of at least ninety (90) days
after the Closing Date (other than pursuant to termination for cause). Purchaser shall pay or assume any accrued vacation time owed to Employees who as of the Closing Date accept employment with Purchaser, and Seller shall
retain responsibility for any severance or other benefits owed to any Employees on the Closing Date. Seller shall comply with any WARN Act, COBRA or other obligations with respect to any Employees who elect not to be employed by the
Purchaser. With respect to Employees who are employed by Purchaser, Purchaser shall comply with any WARN Act, COBRA or other obligations of Purchaser to such Employees following the Closing Date. 
 Section 7.12 Purchaser’s Post-Closing Covenant. 
 (a) Following the Closing Date, and until such time as all principal and interest due and payable under the Notes have been paid in full, Purchaser shall not enter into any new Contract that includes a provision
expressly restricting Purchaser from making the payments required under one or both of the Notes when due. 
 (b) For the
thirty-six (36) month period commencing with the Closing Date, Purchaser shall pursue the Business in good faith, marketing the Active Products in a manner that is commercially reasonable in the context of the Purchaser’s business, as
it may vary during such period. 
 ARTICLE VIII 
 CONDITIONS PRECEDENT TO PURCHASER’S OBLIGATION TO CLOSE 
 Purchaser’s obligation to
