1.2 Excluded Assets. Notwithstanding anything to the contrary in this Agreement, the Acquired Assets shall not include any of the Assets listed on Schedule 1.2 attached hereto (collectively, the “Excluded Assets”).

ARTICLE II

ASSUMED LIABILITIES; EXCLUDED LIABILITIES

2.1 Assumed Liabilities. On the terms and subject to the limitations, exclusions and conditions contained in this Agreement, KVP and Sellers acknowledge that Purchaser is not assuming and under no circumstances shall Purchaser have any liability for any debt, liability or obligation of either Seller, KVP or of the Business, whether vested or contingent, known or unknown, except all Liabilities specifically set forth on Schedule 2.1 attached hereto (collectively, the “Assumed Liabilities”), which Schedule 2.1 includes the list of Contracts that Purchaser agrees to assume at the Closing (the “Assumed Contracts”).

2.2 Excluded Liabilities. Without limiting the generality of Section 2.1, Purchaser is not assuming and, under no circumstances shall it have any liability for: (i) any Plan or any obligation, responsibility, or liability under any Plan including, without limitation, any obligation or liability for notices and/or continued coverage under COBRA with respect to any Person entitled to such coverage under a Plan for any “qualifying event”, as defined under COBRA, occurring prior to, as a result of, or in connection with the Closing; (ii) any salary, bonus, accrued vacation, payroll, severance, workers’ compensation, health care or other benefits obligation, or other reimbursements owed by either Seller or KVP to any of its respective employees, sales agents, independent sales representatives or other Persons with respect to periods on or prior to the Closing Date; (iii) except to the extent that such Taxes have been taken into account in determining OWC, any obligation or liability for Taxes of either Seller or KVP with respect to the Business or the Acquired Assets for any Pre-Closing Tax Periods; (iv) any obligation or liability of either Seller or of KVP for any Taxes that are unrelated to the Acquired Assets or the Business; (v) any obligation or liability of either Seller with respect to violations of any Environmental Laws; (vi) any liability or obligation of either Seller for any tort claims, including, without limitation, claims for product liability, sexual harassment, or employment or other discrimination; (vii) any warranty claims or product liability claims relating to goods sold (including the Products) or services rendered by either Seller prior to the Closing Date; (viii) any liability or obligation of either Seller under the WARN Act or other applicable plant closure law, or liability or obligation arising out of or resulting from the employment or termination of employment by either Seller or KVP of any employees; (ix) any intercompany payables owed by either Seller to any of its respective Affiliates; (x) any notes payable of either Seller in favor of any stockholders, employees or other Affiliates of either Seller or KVP; (xi) all liabilities and obligations of either Seller or KVP under any employment agreement between either Seller or

2.3 Assignment of Contracts and Governmental Authorizations. To the extent that the assignment of any Contract or Governmental Authorization to be assigned to Purchaser pursuant to this Agreement shall require the consent of any other Person, this Agreement shall not constitute a contract to assign the same if an attempted assignment would constitute a breach thereof. Sellers shall use commercially reasonable efforts, and Purchaser shall cooperate as commercially reasonable and appropriate, to obtain any consent necessary to any such assignment. If any such consent is not obtained before the Closing, or if any attempted assignment is ineffective, then Sellers shall after Closing reasonably cooperate with Purchaser in any arrangement reasonably satisfactory to Sellers and Purchaser designed to provide to Purchaser the benefits under any such Contract or Governmental Authorization, including enforcement of any and all rights of Sellers against the other party thereto arising out of breach or cancellation thereof by such other party or otherwise without agreeing to any change to or impairment of the Contract or Governmental Authorization without the consent of Purchaser, which consent shall not be unreasonably withheld, delayed, or conditioned. Notwithstanding anything else set forth in this Section 2.3, neither Seller nor KVP shall be required to (i) take any action that may, in its reasonable judgment, result in a violation of any obligation which such Seller or KVP has to any third party or otherwise violate applicable Law, or (ii) make any payment or offer to grant, or agree to any financial or other accommodation, in order to obtain any such consent or assignment. Sellers shall promptly pay over to Purchaser the net amount (after costs and Taxes) of all payments received by either of them in respect of any such Contract or Governmental Authorization, and Purchaser shall promptly pay, perform or discharge, when due, any and all post-Closing obligations and Liabilities arising thereunder. Purchaser shall indemnify and hold harmless Sellers for any and all Losses incurred as a result of any agreed upon arrangements with respect to any such Contract or Governmental Authorization contemplated by this Section 2.3, except to the extent that such Losses are incurred as a result of the gross negligence or willful misconduct of either Seller.

ARTICLE III

PURCHASE PRICE

3.1 Purchase Price. The aggregate consideration to be paid by Purchaser to Sellers and KVP for the Acquired Assets shall be the sum of (i) Twenty-Four Million Six Hundred Thousand and No/100 Dollars ($24,600,000), subject to adjustment as provided in Section 3.3, and (ii) the aggregate amount of the Earn-Out payments (if any) to Sellers and KVP pursuant to Section 3.4, in an aggregate amount equal to up to Five Million Five Hundred Thousand and No/100 Dollars ($5,500,000), plus (ii) the assumption of the Assumed Liabilities (collectively, the “Purchase Price”). The Purchase Price will be paid as provided in this Article III.

3.2 Payment of Cash Payment at the Closing; Escrowed Funds. At the Closing, subject to the satisfaction or waiver (to the extent permitted by applicable Law) of the

conditions to Closing set forth in Article IX and Article X, and subject to and in accordance with the other terms and conditions of this Agreement, Purchaser shall pay an amount equal to Twenty-Two Million Six Hundred Thousand and No/100 Dollars ($22,600,000), as adjusted pursuant to Section 3.3 (as so adjusted, the “Cash Payment”), to or for the benefit of Sellers and KVP by wire transfer of immediately available funds to the account designated in writing by Sellers and KVP. In addition, at the Closing, Purchaser shall deposit in escrow, by wire transfer to an account (the “Escrow Account”) designated in writing by the Escrow Agent, an amount equal to Two Million and No/100 Dollars ($2,000,000) (the “Escrowed Funds”), which Escrow Account will be created and administered pursuant to the terms of an escrow agreement in substantially the form attached hereto as Exhibit F (the “Escrow Agreement”) in order to satisfy any obligations of Sellers and KVP after the Closing pursuant to Article XI hereof or, in Purchaser’s sole discretion, to satisfy any Final OWC Payment due to Purchaser.

3.3 Working Capital Adjustments to the Purchase Price.

(a) Attached hereto as Schedule 3.3(a) is an estimate of the OWC as of the Closing Date (the “Estimated OWC”), which has been prepared by Sellers and KVP in good faith in accordance with GAAP, in a manner consistent with the principles used in determining the Target OWC, and in conformity with the principles, methodologies, and line items set forth on Exhibit A hereto (collectively, the “Methodology”), which Schedule 3.3(a) includes a reasonably detailed explanation of the calculation of the Estimated OWC and documentation sufficient to confirm the accuracy of such calculation. In the event that the Estimated OWC is greater than Five Million Six Hundred Sixty-Two Thousand and No/100 Dollars ($5,662,000) (the “Lower Limit”) and less than Six Million Two Hundred Fifty-Eight Thousand and No/100 Dollars ($6,258,000) (the “Higher Limit”), there shall be no adjustment to the Cash Payment. If, however, (a) the Estimated OWC is greater than the Higher Limit, then the Cash Payment shall be increased on a dollar-for-dollar basis by an amount equal to the difference between the Estimated OWC and the Higher Limit, or (b) the Estimated OWC is less than the Lower Limit, then the Cash Payment shall be decreased on a dollar-for-dollar basis by an amount equal to the difference between the Lower Limit and the Estimated OWC.

(b) Promptly following the Closing Date, but in no event later than ninety (90) days after the Closing Date, Purchaser will prepare and submit to Sellers and KVP a statement (the “Closing Date Statement”) setting forth in reasonable detail, Purchaser’s calculation of the OWC as of the Closing Date (the “Proposed Final OWC”) prepared in accordance with the Methodology, which shall include a reasonably detailed explanation of the calculation of the Proposed Final OWC and documentation sufficient to confirm the accuracy of such calculation. If Purchaser does not deliver to Sellers and KVP the Closing Date Statement by the ninetieth (90th) day after the Closing Date, Purchaser will be deemed to have accepted the Estimated OWC as the Final OWC. If Sellers and KVP dispute the correctness of the Proposed Final OWC, Sellers or KVP will notify Purchaser in writing of their objections no later than fifteen (15) days after receipt of the Closing Date Statement and will set forth, in writing and in reasonable detail, the amount, nature and basis for Sellers’ or KVP’s objections. If Sellers and KVP fail to deliver their notice of objections within fifteen (15) days after receipt of the Closing Date Statement, Sellers and KVP will be deemed to have accepted Purchaser’s calculation. If Sellers or KVP deliver a notice of objections within such fifteen (15) day period, Sellers, KVP

and Purchaser will endeavor in good faith to resolve any disputed matters no later than fifteen (15) days after Purchaser’s receipt of Sellers’ or KVP’s notice of objections. If Sellers, KVP and Purchaser are unable to resolve the disputed matters, Sellers, KVP and Purchaser will appoint the Accounting Firm to resolve the matters in dispute in a manner consistent with this Section 3.3(b), and the determination of the Accounting Firm in respect of the correctness of each matter remaining in dispute will be final, binding and conclusive on the Parties. The determination of the Accounting Firm will be based solely on presentations by Sellers, KVP and Purchaser and will not be by independent review. The fees and expenses of the Accounting Firm will be paid one-half by Sellers and KVP and one-half by Purchaser. The OWC as of the Closing Date, as finally determined pursuant to this Section 3.3(b) (whether by failure of Purchaser to deliver the Closing Date Statement, by failure of Sellers or KVP to deliver any notice of objections, by agreement of Sellers, KVP and Purchaser or by determination of the Accounting Firm), is referred to herein as the “Final OWC”.

(c) (i) If each of the Estimated OWC and the Final OWC is greater than the Lower Limit and less than the Higher Limit, there shall be no adjustment to the Purchase Price paid to either Sellers and KVP or Purchaser with respect to the Final OWC.

(ii) If an adjustment to the Purchase Price is made at Closing on account of the statement of Estimated OWC provided under Section 3.3(a) and the Final OWC is less than the Estimated OWC, the amount of the difference between the Estimated OWC and the Final OWC shall be paid by Sellers or KVP to Purchaser. If an adjustment to the Purchase Price is made at Closing on account of the statement of Estimated OWC provided under Section 3.3(a) and the Final OWC is greater than the Estimated OWC, the amount of the difference between the Final OWC and the Estimated OWC shall be paid by Purchaser to Sellers or KVP. Notwithstanding anything to the contrary herein, Purchaser, KVP and Sellers acknowledge and agree that no amounts that fall between the Higher Limit and the Lower Limit are intended to be paid by one Party to the other pursuant to this Section 3.3(c)(ii), it being understood that the portion of difference between the Estimated OWC and the Final OWC that falls within such range shall not be included in the amount of the payment due to a Party under this Section 3.3(c)(ii).

(iii) If no adjustment to the Purchase Price is made at Closing on account of the statement of Estimated OWC provided under Section 3.3(a) because the Estimated OWC was greater than the Lower Limit and less than the Higher Limit, but the Final OWC is less than the Lower Limit, the amount of the difference between the Lower Limit and the Final OWC shall be paid by Sellers or KVP to Purchaser. If no adjustment to the Purchase Price is made at Closing on account of the statement of Estimated OWC provided under Section 3.3(a) because the Estimated OWC was greater than the Lower Limit and less than the Higher Limit, but the Final OWC is greater than the Higher Limit, the amount of the difference between the Final OWC and the Higher Limit shall be paid by Purchaser to Sellers or KVP.

(d) Any amounts payable by Sellers pursuant to Section 3.3(c) (any such payment pursuant to the applicable subsection of Section 3.3(c), the “Final OWC Payment”) will be made not later than five (5) Business Days after the determination of the Final OWC by wire transfer of immediately available funds to an account designated in advance in writing by

Purchaser. Any amounts payable by Purchaser pursuant to Section 3.3(c) will be made not later than five (5) Business Days after the determination of the Final OWC by wire transfer of immediately available funds to an account designated in advance in writing by Sellers and KVP.

3.4 Earn-Out.

(a) Generally. In addition to the Cash Payment referred to in Section 3.2 above, Purchaser shall pay to Sellers and KVP an aggregate additional amount of up to Five Million Five Hundred Thousand and No/100 Dollars ($5,500,000) in a contingent Earn-Out (the “Earn-Out”), with such Earn-Out to be calculated and determined in accordance with this Section 3.4, based on EBITDA earned by Purchaser or its Affiliates with respect to the sale of the Products during the periods specified below.

(b) Determination of Earn-Out. Subject in all cases to the limitation provided in Section 3.4(c) below, the Earn-Out will be earned and paid as follows:

(i) First Twelve Months Earn-Out. For every dollar of EBITDA earned by Purchaser or its Affiliates with respect to sales of the Products during months one through twelve following the Closing Date (the “First Earn-Out Period”) above Seven Million Four Hundred Thousand and No/100 Dollars ($7,400,000), Sellers and KVP will receive Three and No/100 Dollars ($3.00), up to a maximum of One Million Eight Hundred Thirty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,833,333.33) (the payment, if any, referred to in this Section 3.4(b)(i) is referred to herein as the “First Earn-Out”).

(ii) Second Twelve Months Earn-Out. For every dollar of EBITDA earned by Purchaser or its Affiliates with respect to sales of the Products during months thirteen through twenty-four following the Closing Date (the “Second Earn-Out Period”) above Eight Million Four Hundred Thousand and No/100 Dollars ($8,400,000), Sellers and KVP will receive Three and No/100 Dollars ($3.00), up to a maximum of One Million Eight Hundred Thirty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,833,333.33) (the payment, if any, referred to in this Section 3.4(b)(ii) is referred to herein as the “Second Earn-Out”). In addition, to the extent that the First Earn-Out is not fully earned during the First Earn-Out Period, for every dollar of EBITDA earned by Purchaser or its Affiliates with respect to sales of the Products during the Second Earn-Out Period above Seven Million Four Hundred Thousand and No/100 Dollars ($7,400,000), Sellers and KVP will receive One and 50/100 Dollars ($1.50), up to a maximum of One Million Three Hundred Thirty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,333,333.33). The Parties agree that in no event shall the total payments under Sections 3.4(b)(i) and 3.4(b)(ii) exceed Three Million Six Hundred Sixty-Six Thousand Six Hundred Sixty-Six and 66/100 Dollars ($3,666,666.66).

(iii) Third Twelve Months Earn-Out. For every dollar of EBITDA earned by Purchaser or its Affiliates with respect to sales of the Products during months twenty-five through thirty-six following the Closing Date (the “Third Earn-Out Period”) above Eight Million Nine Hundred Thousand Dollars ($8,900,000), Sellers and KVP will receive Three and No/100 Dollars ($3.00), up to a maximum of One Million Eight Hundred Thirty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,833,333.33) (the payment, if any, referred

to in this Section 3.4(b)(iii) is referred to herein as the “Third Earn-Out”). In addition, to the extent that the Second Earn-Out is not fully earned during the Second Earn-Out Period, for every dollar of EBITDA earned by Purchaser or its Affiliates with respect to sales of the Products during the Third Earn-Out Period above Eight Million Four Hundred Thousand and No/100 Dollars ($8,400,000), Sellers and KVP will receive One and 50/100 Dollars ($1.50), up to a maximum of One Million Three Hundred Thirty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,333,333.33).

(iv) Fourth Twelve Months Earn-Out. In addition, to the extent that the Third Earn-Out is not fully earned during the Third Earn-Out Period, for every dollar of EBITDA earned by Purchaser or its Affiliates with respect to sales of the Products during the twelve months following the Third Earn-Out Period (the “Fourth Earn-Out Period”) above Eight Million Nine Hundred Thousand and No/100 Dollars ($8,900,000), Sellers and KVP will receive One and 50/100 Dollars ($1.50), up to a maximum of One Million Three Hundred Thirty-Three Thousand Three Hundred Thirty-Three and 33/100 Dollars ($1,333,333.33) (the payment, if any, referred to in this Section 3.4(b)(iv) is referred to herein as the “Fourth Earn-Out”).

(v) Intent of the Parties. It is the intent of the Parties that EBITDA, determined for purposes of computing the Earn-Out payments, if any, be an equitable measure of the performance of the Business without giving effect to acquisition of similar assets or businesses in the future or to extraordinary revenues and expenses associated with the operation of the Business by Purchaser after the Closing, and each Party agrees to cooperate in good faith toward the determination of EBITDA in a manner consistent with such intent. The Earn-Out payments, if any, represent additional consideration for the Acquired Assets and are not intended to be royalty payments.

(c) Earn-Out Cap. For clarity and avoidance of doubt, in no event will total aggregate payments made under this Section 3.4 exceed Five Million Five Hundred Thousand and No/100 Dollars ($5,500,000).

(d) Earn-Out Payment and Earn-Out Statement. Purchaser shall deliver to Sellers and KVP within ninety (90) calendar days of the end of each Earn-Out Period: (a) Purchaser’s unaudited, internally-prepared financial statements covering such period, which financial statements will include normal year-end adjustments for each Earn-Out Period as if such Earn-Out Period were a fiscal year of Purchaser, and (b) a statement setting forth the computation and amount of the First Earn-Out, the Second Earn-Out, the Third Earn-Out or the Fourth Earn-Out, as the case may be (each, an “Earn-Out Statement”), and shall pay the First Earn-Out, the Second Earn-Out, the Third Earn-Out or the Fourth Earn-Out, if any, with respect to the corresponding period, to Sellers and KVP within thirty (30) calendar days following the delivery of the Earn-Out Statement for the corresponding period. Notwithstanding the foregoing, if a Disagreement Letter is delivered to Purchaser by Sellers (as provided in Section 3.4(e) below), Purchaser shall pay to Sellers and KVP the applicable Earn-Out payment or the additional amount of any Earn-Out payment, if any, within three (3) Business Days of final determination of Purchaser’s obligation for such Earn-Out in accordance with Section 3.4(e) hereof (it being understood that undisputed amounts nonetheless shall be paid in accordance with the immediately preceding sentence). Any payment to Sellers and KVP required under this

Section 3.4 shall be paid by wire transfer of immediately available funds to the account designated in writing by Sellers and KVP. During each Earn-Out Period, Purchaser agrees to provide quarterly unaudited, internal financial statements to Sellers and KVP within thirty (30) calendar days after each March 31, June 30, September 30 and December 31 during such Earn-Out Period. Notwithstanding the foregoing, Purchaser shall only be obligated to comply with this Section 3.4(d) with respect to the Fourth Earn-Out Period if the Third Earn-Out is not fully earned during the Third Earn-Out Period.

(e) Objections. Sellers and KVP shall have the right after receipt of an Earn-Out Statement to review the books and records of Purchaser related to the computation the Earn-Out corresponding to the period covered by the Earn-Out Statement, and upon receipt of five (5) Business Days’ prior written notice, Purchaser shall promptly make available such books and records to Sellers and KVP. Sellers and KVP shall have thirty (30) calendar days after such access is granted to furnish Purchaser with a letter (a “Disagreement Letter”) setting forth with specificity those items with which Sellers and KVP disagree and the reasons for each such disagreement. The Parties shall promptly seek to reconcile any such disagreement set forth in the Disagreement Letter; however, if they fail to reach an agreement within thirty (30) calendar days after receipt by Purchaser of the Disagreement Letter, then the Accounting Firm shall be retained by Purchaser, Sellers and KVP to settle any remaining disagreement, and the decision of said firm shall be final and binding on all Parties. The fees of the Accounting Firm shall be borne by Purchaser if the Accounting Firm determines that Purchaser owes an additional Earn-Out payment amount and by Sellers and KVP if the Accounting Firm determines that Purchaser does not owe an additional Earn-Out payment amount.

(f) Sellers’ Acknowledgment. Sellers and KVP acknowledge that the payment of any of the First Earn-Out, Second Earn-Out, Third Earn-Out or Fourth Earn-Out are speculative and subject to, among other things, the future performance of Purchaser and the Business and general economic conditions, which cannot be predicted with accuracy. Accordingly, Purchaser makes no representations, warranties, covenants or guaranties as to the future performance of the Business or the payment of any Earn-Out, except that Purchaser covenants and agrees that it will operate the Business pursuant to reasonable business judgment standards and in good faith, and that Purchaser will make capital expenditures or capital contributions in the ordinary course of business and consistent with past practices of the Business. Consistent with the foregoing, Purchaser shall have no obligation by virtue of this Agreement to make capital expenditures or capital contributions in excess of those made in the ordinary course of business and consistent with past practices of the Business prior to the Closing.

(g) Interest. Notwithstanding anything in this Agreement to the contrary, if any of the First Earn-Out, the Second Earn-Out, the Third Earn-Out or the Fourth Earn-Out is payable under Section 3.4(d) and is not paid in full when due thereunder (including, without limitation, the failure to make an Earn-Out payment because of a prohibition on such payment under the terms of the Subordination Agreements described in Section 10.7 below), then Purchaser also will pay to Sellers and KVP interest on the unpaid amount of the obligation for each day from the date such amount became due under Section 3.4(d) until payment in full,

payable on demand, at the fluctuating rate per annum which at all times will be three percentage points (3%) in excess of the rate that Citibank, N.A. (or any successor entity) publishes from time to time as its prime lending rate.

3.5 Allocation of Purchase Price. As of the Closing, the Purchase Price and Assumed Liabilities will be allocated among the Acquired Assets in the manner provided on Schedule 3.5, which Schedule has been prepared in accordance with Code Section 1060 and the Treasury regulations thereunder. Prior to Closing, Sellers shall deliver to Purchaser a draft of Schedule 3.5 (estimated as of the Closing Date). Within thirty (30) days following the final adjustment to Purchase Price pursuant to Section 3.3, Sellers shall prepare and deliver to Purchaser a revised schedule reflecting the allocation of such adjustments. Purchaser shall within fifteen (15) days after receipt of such schedule or revised schedule, as the case may be, give written notice to Sellers of its agreement or disagreement with such allocation. If Purchaser objects to Sellers’ allocation, Purchaser shall give Sellers written notice of the objections, and Sellers and Purchaser shall use commercially reasonable efforts to resolve the differences. If within thirty (30) days after the date on which Purchaser has given Sellers notice of any objections, the Parties have not resolved such differences, any dispute related thereto shall be referred to the Accounting Firm and resolved within thirty (30) days after such referral. The Accounting Firm’s determination shall be final, binding and conclusive upon Purchaser, Sellers and their respective Affiliates. The costs, expenses and fees of the Accounting Firm with respect to the resolution of any such allocation dispute shall be borne one-half by Sellers and one-half by Purchaser. The allocation determined pursuant to the provisions of this Section 3.5 shall be referred to as the “Allocation Agreement.” Purchaser, Sellers and their respective Affiliates shall be bound by the Allocation Agreement and shall, as applicable, (a) complete and execute a Form 8594 Asset Acquisition Statement under Code Section 1060 in a manner consistent with the Allocation Agreement, (b) file a copy of such Form 8594 with their respective Tax Returns for the period which includes the Closing and provide a copy of such Form 8594 to the other party hereto, and (c) prepare all financial statements and Tax Returns in a manner consistent with the Allocation Agreement. None of the Parties or their Affiliates shall take any action or position for Tax or accounting purposes that is inconsistent with the Allocation Agreement, unless otherwise required by the relevant Taxing Authority.

Except as otherwise set forth in the Seller Disclosure Schedules, each Seller and KVP, as applicable, hereby jointly and severally represent and warrant to Purchaser as of the Closing Date as follows (it being agreed and understood that (i) any matter set forth for purposes of this Article V in any section of the Seller Disclosure Schedules shall be deemed to be an exception or qualification with respect to all other applicable representations and warranties contained in this Agreement to the extent that the applicability of such exception or qualification is readily apparent on the face of such disclosure, and (ii) no reference to or disclosure of any item on the Seller Disclosure Schedules shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed on the Seller Disclosure Schedules):

5.1 Organization, Power, Authority and Good Standing.

(a) PDI is a corporation duly organized, validly existing and in good standing under the laws of the State of New York. Each of DrugTech and KVP is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. Each Seller is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction where the character of the property owned or leased by such Seller or the nature of such Seller’s activities makes such qualification necessary, except where the failure to be so qualified would not reasonably be expected to have, individually or in the aggregate, a Seller

Material Adverse Effect.

(b) Each Seller and KVP has the requisite corporate power and authority to execute, deliver and perform its respective obligations under this Agreement and the Ancillary Agreements to which it is a party. The execution and delivery of this Agreement and the Ancillary Agreements to which either Seller or KVP is a party and the performance of all of each Seller’s and KVP’s obligations hereunder and under the Ancillary Agreements to which it is a party in connection with the Contemplated Transactions have been duly authorized by all requisite corporate action on the part of each Seller and KVP. This Agreement and each Ancillary Agreement to which either Seller or KVP is a party, as applicable, has been validly executed and delivered by each Seller and KVP, as applicable, and, assuming the due authorization, execution and delivery by the other parties thereto, constitutes, and each Ancillary Agreement to which each Seller or KVP is a party that is to be executed and delivered by such Seller or KVP, as applicable, will constitute when executed and delivered by such Seller or KVP, as applicable (assuming that such Ancillary Agreement to which it is a party has been duly authorized, executed and delivered by the other parties thereto to the extent applicable), a valid and binding obligation of such Seller or KVP, as applicable, enforceable against such Seller and KVP, as applicable, in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors’ rights generally. PDI represents that it is qualified to do business in the State of Missouri. KVP owns one hundred percent (100%) of the equity interest in each Seller. Neither Seller has any Subsidiaries.

5.2 No Conflicts; Consents.

(a) The execution, delivery and performance of this Agreement and the Ancillary Agreements to which it is a party by each Seller and KVP, as applicable, (i) is not prohibited or limited by, and will not result in the breach of or a default under, any provision of the Certificate of Incorporation or Bylaws of either Seller or of KVP; (ii) do not conflict with, violate or require that any notice be given under the Consent Decree; (iii) assuming all of the consents, approvals, authorizations and permits described in Section 5.2(b) have been obtained, all the filings and notifications described in Section 5.2(b) have been made and any waiting periods thereunder have terminated or expired, do not conflict with any Law applicable to either Seller or to KVP; and (iv) do not conflict with, result in a breach of, constitute a default under, result in the acceleration of obligations under, create in any party the right to terminate, modify or cancel, or require any notice, consent or waiver under, any agreement or instrument binding on either Seller or on KVP or any other applicable order, writ, injunction or decree of any court or Governmental Entity to which either Seller or KVP is a party or by which either Seller or KVP is bound or to which any of the Acquired Assets is subject, except in each case as set forth in clauses (iii) and (iv) above, if such event would not reasonably be expected to have, individually or in the aggregate, a Seller Material Adverse Effect.

(b) No notice to, filing with, authorization of, exemption by, or consent of, any Person, including any Governmental Entity, or expiration of any required waiting period, is required for Sellers and KVP to consummate the Contemplated Transactions, except where the failure to make such filings or notifications, or obtain such consents, approvals, authorizations,

permits, or waiting period expirations, would not reasonably be expected to have, individually or in the aggregate, a Seller Material Adverse Effect.

5.3 Title to, Condition and Sufficiency of Assets. Each Seller has good and valid title to all the Acquired Assets owned by it, except in the case of the Acquired Assets that have been sold or otherwise disposed of in the ordinary course of business consistent with past practices and not in violation of this Agreement, in each case free and clear of all Encumbrances, other than Permitted Encumbrances. All equipment and personal property that is part of the Acquired Assets (other than Inventory) is maintained in good operating condition for the purposes for which it is currently being used, reasonable wear and tear excepted. Except as otherwise expressly contemplated in the Transition Services Agreement, the Acquired Assets comprise all of the Assets that are both used by PDI and necessary to conduct the Business as conducted by PDI as of the Closing Date. At the Closing, upon delivery of and payment for the Acquired Assets in accordance with the terms of this Agreement, Purchaser will acquire good and valid title to all of the Acquired Assets, in each case free and clear of all Encumbrances, other than Permitted Encumbrances and any Encumbrances created by any actions of Purchaser or its Affiliates.

5.4 Books and Records. The Books and Records are true and complete in all material respects and have been maintained in accordance with sound business practices, and reasonably reflect, in reasonable detail, all material transactions involving the Acquired Assets, the Assumed Liabilities and the Business.

5.5 Intellectual Property.

(a) Each Seller owns or possesses all right, title and interest in, to and under the Intellectual Property owned by it or used in the Business or the sale and marketing of the Products.

(b) No claim by any third party contesting the validity, enforceability, or ownership of the Intellectual Property has been made and is currently outstanding against either Seller, nor to the Knowledge of Sellers, is any threatened.

(c) Neither Seller nor KVP has given any notice to any third parties asserting infringement by such third party of the Intellectual Property.

(d) To the Knowledge of Sellers, the use of the Intellectual Property in connection with the conduct of the Business and the sale and marketing of the Products does not infringe or misappropriate any intellectual property rights of any third parties.

(e) Neither Seller nor KVP has granted any licenses to the Intellectual Property to third parties; and neither Seller nor, to the Knowledge of Sellers, any other Person, is party to any agreements with third parties that limit or restrict use of the Intellectual Property as presently used in the Business or require any royalty or similar payments for its use.

(f) All past and present employees of Sellers and KVP who are or have been

substantively involved in the development of the Intellectual Property have executed written agreements or are otherwise obligated to vest in Sellers or KVP exclusive ownership of such Intellectual Property. Schedule 5.5 of the Seller Disclosure Schedules sets forth a list, as of the Closing Date, of all applications for registration or issued registrations relating to the Intellectual Property owned by either Seller. All such applications for registration are pending as of the Closing Date or, to the extent indicated, have been issued by the United States Patent and Trademark Office or other corresponding applicable Governmental Entity. Except for licenses relating to off-the-shelf commercial software programs, there are no (a) licenses to Sellers or KVP of Intellectual Property rights not owned by Sellers that are used by Sellers in the Business, or (b) Intellectual Property rights that are owned by Sellers and licensed to third parties.

(g) Sellers and KVP have taken reasonable measures to protect and preserve the confidentiality of the Product Know-How. To the Knowledge of Sellers, no Product Know-How owned by either Seller that is material to the Business has been disclosed to any third party other than pursuant to a written non-disclosure agreement. Neither Seller nor KVP nor, to the Knowledge of Sellers, any party with which either has contracted are in breach of any license, sub-license, option, charge or assignment to which either Seller or KVP is a party in respect of any Intellectual Property (including Product Know-How); and the Contemplated Transactions will not result in any breach of any such agreement or otherwise result in any such agreement being subject to termination by any such party.

(h) Except as expressly set forth in the Transition Services Agreement, the Intellectual Property hereunder comprises all of the intellectual property that is used by PDI in and material to the Business as such Business is conducted by PDI as of the Closing Date.

5.6 Contracts.

(a) Schedule 5.6 of the Seller Disclosure Schedules lists all material Contracts to which PDI is a party as of the Closing Date (but excluding the Leases, which are covered by Section 5.15) (the “Material Contracts”), including (i) any other lease, sublease or similar Contract with any Person pursuant to which PDI is a sublessor of, or makes available for use to any Person any portion of any premises otherwise occupied by PDI; (ii) any joint venture, partnership or other Contracts involving the sharing of profits or losses; (iii) any Contract creating or granting any Encumbrance (other than Permitted Encumbrances) upon any of the Acquired Assets; (iv) any Contract under which PDI has granted or received exclusive or non-exclusive rights or another Person processes, produces or manufactures, or will process, produce or manufacture, Products; (v) any Contract with a customer, supplier or distributor involving amounts in excess of $100,000; (vi) any currently effective Contract, or any expired or terminated Contract which has surviving provisions providing for indemnification of any Person by PDI with respect to Liabilities relating to the Business; and (vii) any other Contract having an aggregate value over its remaining term in excess of $100,000. Schedule 5.6 excludes any Contract that involves or is reasonably expected to involve the payment of consideration having an aggregate value of less than $100,000, but only in those cases where such Contract is not material to the Business.

(b) PDI has made available to Purchaser copies of each Material Contract that

is also an Assumed Contract, which are accurate and complete in all material respects, together with all amendments and supplements thereto. Each Material Contract that is also an Assumed Contract constitutes a legal, valid and binding agreement of PDI. PDI is not in violation of, in breach of, or in default under, nor, to the Knowledge of Sellers, has there occurred an event or condition which (with or without notice or lapse of time or both) would constitute a violation of, breach of, or default under, any such Material Contract that is also an Assumed Contract, by PDI.

5.7 Compliance with Laws; Regulatory Matters.

(a) Except as otherwise disclosed in the Specified KVP Filings, PDI is conducting its business and operations in material compliance with all applicable Laws, including without limitation the applicable provisions of the Federal Food, Drug, and Cosmetic Act (the “FD&C Act”), 21 U.S.C. §301 et. seq., the applicable regulations promulgated thereunder, and applicable guidance, standards and policies issued by FDA, it being understood that for purposes of Sellers’ and KVP’s indemnification obligations pursuant to Section 11.2 hereof, the “materiality” qualifier in the first part of this sentence shall be disregarded. No Governmental Entity has served notice that either Seller was or is in violation of any Law in any jurisdiction. Neither Seller has received written notice from any Governmental Entity that there are any circumstances currently existing that would lead to any loss or refusal to renew any Governmental Authorizations on terms less advantageous to such Seller than the terms of those Governmental Authorizations currently in force, except in the case of any such violation, loss or refusal to renew that would not adversely impact Purchaser’s ability to conduct the Business after the Closing. The Consent Decree does not apply to PDI, the Products or the Business.

(b) (i) To the Knowledge of Sellers, as of the Closing Date, PDI has filed with FDA all required notices, supplemental applications and annual or other reports, including adverse experience reports, with respect to each Product that is material to the conduct of the manufacture, marketing, distribution and sale of the Products as conducted by PDI as of the Closing Date. All such notices, applications and reports filed within the past twelve (12) months are listed on Schedule 5.7(b)(i).

(ii) PDI has not received any written notice that any Governmental Entity (including FDA) (A) has commenced, and, to the Knowledge of Sellers, no Governmental Entity has threatened to initiate, any action to withdraw its approval or request the recall of any Product, or (B) has commenced or, to the Knowledge of Sellers, has threatened to initiate, any action to enjoin production of any Product. Neither Seller has received any Form 483 or other similar notification under the FD&C Act with respect to the Business.

PDI.

5.8 Litigation.

(a) There is no Proceeding pending or, to the Knowledge of Sellers, threatened against either Seller in respect of the Acquired Assets, the Products or the Contemplated Transactions, in respect of which Purchaser would or would reasonably be expected to become liable as a result of the Contemplated Transactions.

(b) There are no outstanding orders, injunctions or decrees of any Governmental Entity (other than the Governmental Authorizations) that apply to the Acquired Assets (or that apply to KVP or either Seller and will apply to Purchaser after the Closing Date) that restrict the ownership, disposition or use of the Acquired Assets.

5.9 Brokers or Finders. No broker, investment banker, agent, finder or other intermediary acting on behalf of either Seller or under the authority of either Seller, except for Quetico Partners LLC, is or will be entitled to any broker’s or finder’s fee or any other commission or similar fee directly or indirectly in connection with the Contemplated Transactions. The fees of Quetico Partners LLC shall be the sole responsibility of Sellers.

5.10 Inventory. Subject to amounts reserved therefor on the Financial Statements, the values at which Inventory is carried on the Financial Statements reflect, in all material respects, the historical inventory valuation policy of PDI of stating such Inventory at the lower of cost (determined on a first in, first out basis) or market value. All of the items included in Inventory on the Closing Date consist of a quality and quantity usable and, with respect to finished Products, saleable, in the ordinary course of business, and such Inventory does not include any item of inventory that is obsolete, damaged or that has been previously written off by PDI. Items of below-standard quality and items not readily saleable in the ordinary course of business have been written down in value in accordance with GAAP to estimated net realizable market value by PDI. PDI has good and valid title to its Inventory free and clear of all Encumbrances, other than Permitted Encumbrances. All Inventory held on consignment or otherwise by third Persons are properly reflected and accounted for in the Financial Statements in accordance with GAAP. The Inventory meets all applicable Product specifications of PDI and the Business.

5.11 Financial Information. Schedule 5.11 of the Seller Disclosure Schedules contains true, correct and complete copies of the unaudited internally generated balance sheets and income statements for the Business for the fiscal years ending March 31, 2008, March 31, 2009, and March 31, 2010, and the unaudited balance sheets and statements of income for the month of April 2010 (all of the foregoing being hereinafter collectively called the “Financial Statements”). The Financial Statements have been prepared in accordance with GAAP, in all material respects, applied on a consistent basis for the periods involved, except for (a) the absence of footnotes, and (b) with respect to the April 2010 interim statements only, ordinary year-end adjustments, and have been prepared from and are consistent in all material respects with the Books and Records. The Financial Statements fairly present in all material

respects the financial condition and results of operations of the Business.

5.12 Absence of Undisclosed Liabilities. To the Knowledge of Sellers, there are no Liabilities of PDI, and there is no existing fact, condition or circumstance which could reasonably be expected to result in Liabilities to PDI, except Liabilities (a) disclosed in the Financial Statements, (b) incurred since December 31, 2009 in the ordinary course of business, (c) for the future performance of obligations of PDI pursuant to the terms of Contracts to which PDI is a party, (d) set forth on Schedule 5.12 of the Seller Disclosure Schedules, (e) disclosed in the Specified KVP Filings, or (f) for brokers, counsel, other consultants and other costs incurred in connection with the Contemplated Transactions.

Sellers and KVP, jointly and severally (and notwithstanding any baskets, caps, or other limitations on Sellers or KVP’s indemnification obligations under Article XI, which for purposes of this Section 7.6, will not apply to any Product Recall initiated within the one (1) year period after the Closing Date that relates to Products sold, shipped or distributed prior to the Closing Date), will be solely responsible for the cost and expense of any Product Recall that is initiated by PDI under this Section 7.6. Nothing in this Section 7.6 will be construed as a limitation on or waiver of Purchaser’s right to indemnification under Article XI hereto with respect to, or in connection with, any Product Recall or any breach of this Agreement or the representations, warranties or covenants set forth herein.

7.7 Tax Matters.

(a) Sellers and KVP shall indemnify Purchaser and hold Purchaser harmless from and against, without duplication, any Liability attributable to: (i) all Taxes (or the non-payment thereof) of Sellers or KVP with respect to the Acquired Assets or the Business for all periods ending on or before the Closing Date and the portion through the end of the Closing Date for any taxable period that includes (but does not end on) the Closing Date (“Pre-Closing Tax Period”) and all Taxes (or the non-payment thereof) of Sellers or KVP that are unrelated to the Acquired Assets or the Business; (ii) all Taxes of any member (other than a Seller) of an affiliated, consolidated, combined or unitary group of which either Seller (or any predecessor of any of the foregoing) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulation Section 1.1502-6 or any analogous or similar state, local, or foreign law or regulation, and (iii) any and all Taxes of any Person imposed on either Seller as a transferee or successor, by contract or pursuant to any Law, which Taxes relate to an event or transaction occurring before the Closing. Sellers shall reimburse Purchaser for any Taxes of Sellers which are the responsibility of Sellers pursuant to this Section 7.7 within ten (10) Business Days after

either Seller’s receipt of notice from Purchaser that any such Taxes have been paid by Purchaser. Notwithstanding the foregoing, neither Seller nor KVP shall have any responsibility for, and shall not indemnify Purchaser against, Taxes to the extent that such Taxes have been taken into account in determining OWC.

(b) Sellers shall prepare or cause to be prepared and file or cause to be filed all Tax Returns with respect to the Acquired Assets or Business for Sellers for all periods ending on or prior to the Closing Date. Sellers shall pay and discharge all Taxes with respect to the Acquired Assets or Business shown to be due by either Seller on such Tax Returns. Purchaser shall prepare and timely file all returns with respect to Asset Taxes (as defined below) for any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”). Purchaser shall pay and discharge all Taxes shown to be due on such Tax Returns. No later than three (3) Business Days prior to the due date of such return, Sellers shall pay to Purchaser the amount of Taxes shown due which is attributable to the pre-Closing portion of the Straddle Period less any Taxes for such period that were prepaid before Closing but not included in current assets in determining OWC and less any Taxes to the extent the liability for such Taxes was taken into account in determining OWC; provided, however, that Sellers may challenge the amount attributable to it if they believe in good faith that the amounts due on such Tax Returns are materially incorrect. Sellers shall have a reasonable opportunity to review all such Tax Returns prior to paying the foregoing amount of Taxes. For purposes of this Agreement, “Asset Taxes” shall mean real property, personal property and similar taxes (not based on income, profit or gains) relating to the Acquired Assets or the Business.

(c) Notwithstanding anything to the contrary in this Agreement, and except as set forth on Schedule 7.7(c), neither Seller nor KVP shall file any amended Tax Return with respect to the Acquired Assets or Business relating to Sellers with respect to taxable periods ending on or prior to the Closing Date without the written consent of Purchaser (which shall not be unreasonably withheld, conditioned or delayed) if such amendment adversely affects Purchaser, unless required to do so by Law.

(d) Purchaser, on the one hand, and Sellers and KVP, on the other hand, shall cooperate fully, as and to the extent reasonably requested by the other, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information reasonably relevant to any such audit, litigation, or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Sellers and Purchaser agree: (i) to retain all books and records with respect to Tax matters pertinent to the Business or Acquired Assets relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and, to the extent notified by other Parties, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if after such notice is given the other Party so requests, Sellers or Purchaser, as the case may be, shall allow the other party to take possession of such books and records.

(e) All transfer, documentary, stamp, registration and other such Taxes and fees (including any penalties and interest) incurred in connection with the transfer by Sellers to Purchaser of the Acquired Assets pursuant to this Agreement shall be paid by Sellers when due, and Sellers shall, at their own expense, file all necessary Tax Returns and other documentation with respect to all such transfer, documentary, sales, use, stamp, registration and other Taxes and fees, and, if required by applicable Laws, Purchaser shall, and shall cause its Affiliates to, join in the execution of any such Tax Returns and other documentation. Purchaser shall, and shall cause its Affiliates to, execute all documents and take any other actions reasonably requested by either Seller in order to enable either Seller to secure an exemption from, or reduction in the amount of, such Taxes. Purchaser shall pay to either Seller the amount of any such Taxes for which such Seller is responsible to collect and pay to the Tax authority but for which Purchaser is liable for such Tax.

(f) The Parties agree to adopt the standard procedure for reporting wages and other compensation under Revenue Procedure 2004-53.

(g) In the event Sellers become obligated pursuant to the terms of this Section 7.7 to indemnify Purchaser for Taxes, Purchaser must first make written demand to Sellers in accordance with the terms and provisions of this Agreement. If Sellers are unable or unwilling to make such payment within five (5) Business Days of receipt of the aforesaid notice from Purchaser, Purchaser shall then present the written demand to KVP for payment on behalf of Sellers. KVP hereby guarantees payment of any such amounts required to be paid by Sellers to Purchaser under this Section 7.7, and covenants and agrees to pay any such amounts to Purchaser to the extent not paid by Sellers. Nothing set forth herein shall be construed to waive Sellers’ or KVP’s rights to dispute in good faith any Taxes claimed by Purchaser to be owed by Sellers or KVP under this Section 7.7.

(h) Sellers and Purchaser hereby waive compliance with any “bulk sales” Laws (including any requirement to withhold any amount from payment of the Purchase Price) applicable to the sale to Purchaser of the Acquired Assets and the Inventory by Sellers.

7.8 PDI Name Change. Promptly following the Closing Date, PDI will file appropriate documentation with the Secretary of State of the State of New York in order to amend its Certificate of Incorporation to change its name to a name other than “Particle Dynamics, Inc.,” “PDI,” or any derivative thereof.

7.9 Post-Closing Cooperation. Except as otherwise provided in the Transition Services Agreement, Purchaser and Sellers shall use commercially reasonable efforts to cooperate with each other, and shall cause their officers, employees, agents, auditors, Affiliates and Representatives to use commercially reasonable efforts to cooperate with each other to ensure the orderly transition of the Acquired Assets from Sellers to Purchaser and to minimize any disruption to the conduct of the Business and the marketing, distribution and sale of the Products and the other respective businesses of Sellers and Purchaser that might result from the Contemplated Transactions. After the Closing Date, upon reasonable written notice, Purchaser and Sellers shall furnish or cause to be furnished to each other and their employees, counsel, auditors and Representatives access, during normal business hours, to personnel and such

information, documents or records (or copies thereof) at the recipient’s request, cost and expense to the extent reasonably requested by the requesting party in connection with (i) the preparation of Tax Returns or any audit, examination or contest relating to Taxes, (ii) financial reporting and accounting compliance matters, (iii) compliance with the requirements of any Governmental Entity in connection with the transactions contemplated by this Agreement, or (iv) in connection with any actual or threatened Proceeding.

7.10 Non-Competition Agreement.

(a) For a period of five (5) years from and after the Closing Date, anywhere in the world, Sellers and KVP shall not, and shall cause their respective controlled Affiliates not to, directly or indirectly:

(i) engage in, carry on or have any interest in a business substantially similar to the Business as carried on by PDI immediately prior to the Closing Date;

(ii) enter into, engage in, or be employed by or provide consulting services to, or have any interest in any business substantially similar to the Business as carried on by PDI immediately prior to the Closing Date;

(iii) solicit or encourage any Hired Employee to either leave the employment of or cease working for or with Purchaser; provided that the foregoing shall not apply to (x) any Hired Employees no longer employed by Purchaser or any of its Affiliates and (y) any Hired Employees who respond to general solicitations of employment not specifically directed toward Purchaser; or

(iv) induce any customer or supplier of Purchaser or any Subsidiary of Purchaser or the Business to refuse to do business with Purchaser, any Subsidiary of Purchaser or the Business, as the case may be, on as favorable of terms as previously done with PDI or the Business, as the case may be ((i) through (iv) above, the “Restricted Activities”).

(b) Sellers and KVP acknowledge that the length of time and geographic restriction pertaining to all prohibitions in this Section 7.10 both are reasonable and necessary for the legitimate protection of Purchaser’s business and interests.

(c) Notwithstanding the foregoing, but subject in all cases to the Parties’ confidentiality obligations under Section 7.2, this Section 7.10 shall not operate to prevent or restrict:

(i) the acquisition by any Person of any of KVP or its Affiliates, whether by merger, consolidation, share purchase, asset purchase, or otherwise, but only where such Person was not, prior to such acquisition, an Affiliate of KVP;

(ii) any of KVP, either Seller, or their respective Affiliates owning or engaging in any business conducted by any of them on the Closing Date, other than the Business; provided that KVP, Sellers, and their respective Affiliates will, under such circumstances, remain subject to the non-solicitation and non-interference obligations provided under Section

7.10(a)(iii) and Section 7.10(a)(iv) above; or

(iii) the direct or indirect acquisition by KVP or any of its controlled Affiliates (through acquisition, merger or other strategic transaction) of an interest in any Person that engages in the Restricted Activities as long as (A) KVP and its controlled Affiliates’ voting ownership interest in such Person does not exceed five percent (5%) in the aggregate, or (B) KVP or any of its controlled Affiliates, as the case may be, promptly following the earlier of the closing or the announcement of such transaction (and in any event no more than one (1) year after such closing or announcement), sells or otherwise divests the Restricted Activities to a third person or winds-up the Restricted Activities.

Notwithstanding the foregoing exclusions or anything else in this Section 7.10, for a period of five (5) years from and after the Closing Date, under no circumstances will Sellers, KVP, or their respective controlled Affiliates, directly or indirectly, hire or solicit or encourage Xxxx Xxxxx to either leave the employment of, or cease working for or with, Purchaser. Purchaser acknowledges and agrees that, notwithstanding the foregoing, during the nine (9) month period beginning on the Closing Date, Xxxx Xxxxx shall be made reasonably available telephonically and electronically (at no additional cost) to KVP upon reasonable request to answer questions regarding non-PDI matters for which Xx. Xxxxx was responsible or otherwise involved prior to the Closing Date.

(d) Sellers and KVP expressly agree and understand that the remedy at law for any breach by either Seller or KVP of this Section 7.10 will be inadequate and that the damages flowing from such breach may not be readily susceptible to being measured in monetary terms. Accordingly, it is acknowledged that upon adequate proof of either Seller’s or KVP’s violation of this Section 7.10, Purchaser will be entitled to seek immediate injunctive relief and may seek to obtain a temporary restraining order restraining any threatened or further breach. Nothing in this Section 7.10(d) will be deemed to limit Purchaser’s remedies at law or in equity for any breach by either Seller or KVP of any of the other provisions of this Agreement that may be pursued by or available to Purchaser.

(e) In the event any court of competent jurisdiction determines that the specified time period or geographical area set forth in this Section 7.10 is unreasonable, arbitrary or against public policy, then a lesser time period or geographical area that is determined by the court to be reasonable, non-arbitrary and not against public policy may be enforced.

(f) In the event that either Seller or KVP violates any legally enforceable provision of this Section 7.10 as to which there is a specific time period during which such Seller or KVP is prohibited from taking certain actions or engaging in certain activities, then, in such event the violation will toll the running of the time period from the date of the violation until the violation ceases.

7.11 Intellectual Property Matters. KVP and each Seller hereby covenant and agree, from and after the Closing Date, (a) to execute and deliver to Purchaser all such further instruments, assignments, assurances and other documents, and (b) to provide reasonable assistance to Purchaser and to make itself reasonably available to Purchaser at such times as may

be requested by Purchaser, in each instance in connection with the carrying out of this Agreement and the Contemplated Transactions and the vesting in Purchaser of all of the rights, titles, interests and privileges relating to the Intellectual Property intended to be transferred to Purchaser under this Agreement. Notwithstanding the foregoing, for the avoidance of doubt, Purchaser will be responsible for paying all reasonable out-of-pocket expenses incurred in order for KVP or either Seller to perform its obligations under this Section 7.11 and all filing and recording fees required to be paid in connection with the transfer of title of the Intellectual Property to Purchaser including, without limitation, any fees and expenses required by the United States Patent and Trademark Office. None of KVP or either Seller shall incur any out-of-pocket expenses pursuant to Section 7.11 without the prior written approval of Purchaser (which approval shall not be unreasonably withheld).

7.12 Misdirected Receivables. Following the Closing, PDI, DrugTech or KVP, as the case may be, within ten (10) Business Days after the end of each month (as necessary), will forward or remit to Purchaser, by endorsement, wire or electronic transfer, all collections of receivables erroneously received by PDI, DrugTech or KVP, if any, which are part of the Acquired Assets. Following the Closing, if Purchaser notifies KVP by telephone of any receivable erroneously received by PDI, DrugTech or KVP that is part of the Acquired Assets with sufficient specificity to enable PDI, DrugTech or KVP (as applicable) to easily locate such particular receivable, then PDI, DrugTech or KVP, as applicable, will forward or remit to Purchaser, by endorsement, wire or electronic transfer, such received misdirected receivable within three (3) Business Days of such notification by Purchaser. Prior to the close of business on the next Business Day following the Closing, PDI, DrugTech and KVP will close all operating or other accounts previously used to deposit or collect Accounts Receivable in connection with the Business.

ARTICLE VIII

EMPLOYEE MATTERS

8.1 Employees.

(a) In coordination with PDI, Purchaser shall, as of the Closing and in accordance with this Section 8.1, offer employment to all of the Employees. Those Employees who accept such offers of employment shall be new employees of Purchaser or its Affiliates, effective from and after the Closing, and are hereafter referred to as the “Hired Employees”. As soon as practicable following the acceptance or rejection of all offers of employment by Purchaser, Purchaser shall advise PDI of the names of the Hired Employees.

(b) Purchaser shall not assume any Plans or Other Arrangements of PDI or any Affiliate of PDI, any Liabilities thereunder, or any related trust agreements, insurance contracts, or other agreements made in connection with PDI’s or any Affiliate’s Plans and Other Arrangements.

(c) Neither Purchaser nor any of its Affiliates or any of the benefit plans of Purchaser shall have any Liabilities or responsibility for any benefit claim or Liability incurred by or pertaining to any Employee, former employee of PDI or any Affiliate of PDI, or retiree of

PDI or any Affiliate of PDI prior to the Closing, except to the extent expressly provided herein.

(d) PDI agrees to furnish Purchaser and its Affiliates with such information concerning Employees, employee payroll and employee benefit plans, subject to confidentiality and privacy considerations and limitations, as is necessary and appropriate to effect the Contemplated Transactions.

(e) KVP and PDI will cause each Hired Employee who participated in any Pension Plan of PDI, KVP or their Affiliates and who has accrued a benefit under any such plan as of the Closing Date to be fully vested in such benefit as of the Closing Date.

(f) PDI or KVP (as applicable) will terminate the employment of all of the Hired Employees at the conclusion of such employees’ shift or scheduled hours on the day immediately preceding the Closing Date, and in the event any notice is required under the WARN Act or other applicable plant closure law, such notice will be the sole responsibility of PDI or KVP. PDI and KVP hereby covenant and agree that any Liability resulting from the termination of the employment of any Employee of PDI or KVP, whether claims for severance payments or other claims arising from such termination, shall be the responsibility of PDI or KVP, and PDI or KVP will indemnify and hold harmless Purchaser in connection with same. Purchaser shall hire the Hired Employees so terminated, in positions with substantially similar duties and responsibilities, and at substantially similar wages and benefits, as those provided immediately prior to the Closing by PDI or KVP to such Hired Employees. The Parties acknowledge and agree that all Hired Employees hired by Purchaser will be subject to Purchaser’s normal employment policies, practices, and benefits; provided, however, that the standard waiting period for new employees of Purchaser to receive benefits will be waived, and that such benefits will become effective on the first day of the first full month of employment of such individuals by Purchaser.

(g) No provision in this Agreement shall modify or amend any documents setting forth the terms of any Plan and Other Arrangement or any related agreements or other funding document. This shall not prevent the Parties entitled to enforce this Agreement from enforcing any provision in this Agreement, but no other person shall be entitled to enforce any provision in this Article VIII on the grounds that it is an amendment to another agreement, plan, program, or document. If a person not entitled to enforce this Agreement brings a lawsuit or other action to enforce any provision in this Article VIII as an amendment to another agreement, plan, program, or document, and that provision is construed to be such an amendment despite not being explicitly designated as one in this Agreement, that provision in this Agreement shall be void ab initio, thereby precluding it from having any amendatory effect.

Claims for indemnification under this Article XI for breaches of representations and warranties must be made within the periods of limitation set forth in this Section 11.1 (excluding claims for fraud and for breaches of covenants and agreements); provided, however, that such obligations to indemnify and hold harmless shall not terminate with respect to any item as to which the Person to be indemnified shall have, before the expiration of the applicable survival period, as above set forth, previously made a claim by delivering a notice of such claim (stating in reasonable detail the basis of such claim) pursuant to Section 11.4 to the party to be providing the indemnification, but only as to the matters contained in such notice.

(a) Subject to the terms of this Article XI, after the Closing, Sellers and KVP, jointly and severally, shall indemnify Purchaser and its Affiliates and each of their respective officers, directors, employees, stockholders, agents and representatives (“Purchaser Indemnified Persons”) against, and hold them harmless from, any Losses, as incurred (payable promptly upon written request), to the extent arising out of or resulting from:

(b) Neither Seller nor KVP shall have any indemnification obligations pursuant to Section 11.2(a)(i), except to the extent that the aggregate amount of Losses incurred or suffered by Purchaser that Sellers and KVP are otherwise responsible for under Section 11.2(a)(i) exceeds Two Hundred Fifty Thousand and No/100 Dollars ($250,000) (the “Indemnity Threshold”), at which time Purchaser shall be entitled to assert claims against Sellers and KVP for Losses in excess of, but excluding, the Indemnity Threshold, except for claims based on fraud; provided, that neither Seller nor KVP shall have any indemnification obligations pursuant

to Section 11.2(a)(i) for any individual claim for Losses of less than Two Thousand and No/100 Dollars ($2,000) and no such claim shall be included in calculating the Indemnity Threshold; and provided further, that the maximum aggregate liability of Sellers and KVP for all claims by Purchaser under Section 11.2(a)(i) shall not exceed (collectively, subsections (i) through (iv) shall be referred to as the “Indemnity Caps”):

11.3 Indemnification by Purchaser.

(a) Subject to the terms of this Article XI, after the Closing, Purchaser shall indemnify Sellers, KVP, their Affiliates and each of their respective officers, directors, employees, stockholders, agents and representatives (“Seller Indemnified Persons”) against, and agrees to hold them harmless from, any Loss, as incurred (payable promptly upon written request), to the extent arising out of or resulting from:

(i) any breach of any representation or warranty of Purchaser that survives the Effective Time and is contained in this Agreement or the Purchaser’s Certificate;

(ii) any breach of any covenant of Purchaser contained in this Agreement or in any Ancillary Agreement;

(iii) any Assumed Liabilities; and

(ii) except for claims based on fraud, in the case of any liability pursuant to Section 11.1(d) above, the General Reps Indemnity Cap in the aggregate.

11.4 Indemnification Procedures.

(a) Notice of Third Party Claims. In order for a party (the “Indemnified Party”) to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim made by any Person against the Indemnified Party (a “Third Party Claim”), such Indemnified Party must notify the indemnifying party (the “Indemnifying Party”) in writing (and in reasonable detail) of the Third Party Claim within fifteen (15) Business Days after receipt by such Indemnified Party of notice of the Third Party Claim. Failure to provide such notice shall not act as a waiver of the Indemnified Party’s rights with respect to indemnification hereunder (i) so long as such notice is delivered in accordance with Section 11.4 prior to the expiration of the applicable survival period for such claim specified in Section 11.1 or (ii) unless, and to the extent that, such failure prejudices the Indemnifying Party’s ability to defend against, reduce or eliminate Losses arising out of such Third Party Claim. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five (5) Business Days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

(b) Defense of Third Party Claims. If a Third Party Claim is made against an Indemnified Party, the Indemnifying Party shall be entitled to participate in the defense thereof and, if it so chooses, to assume the defense thereof with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnifying Party. Should the Indemnifying Party so elect to assume the defense of a Third Party Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof. If the Indemnifying Party assumes such defense, the Indemnified Party shall have the right to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Party, it being understood that the Indemnifying Party shall control such defense. The Indemnifying Party shall be liable for the fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof (other than during any period in which the Indemnified Party shall have failed to give notice of the Third Party Claim as provided above). If the Indemnifying Party chooses to defend or prosecute a Third Party Claim, all the Indemnified Parties shall cooperate in the defense or prosecution

thereof. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such Third Party Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Whether or not the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnifying Party’s prior written consent (which consent shall not be unreasonably withheld). If the Indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party shall agree to any settlement, compromise or discharge of a Third Party Claim that the Indemnifying Party may recommend and that by its terms obligates the Indemnifying Party to pay the full amount of the liability in connection with such Third Party Claim, which releases the Indemnified Party completely in connection with such Third Party Claim and that would not otherwise materially adversely affect the Indemnified Party.

(c) Direct Claims. In the event any Indemnified Party should have a claim against any Indemnifying Party under Section 11.2 or Section 11.3 that does not involve a Third Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver written notice of such claim (a “Direct Claim Notice”) to the Indemnifying Party within thirty (30) days after obtaining actual knowledge thereof, stating the nature and basis of such claim and the amount thereof, in reasonable detail. Failure to provide such Direct Claim Notice within such thirty (30) day period shall not act as a waiver of the Indemnified Party’s rights with respect to such claim (i) except as provided in Section 11.4 prior to the expiration of the applicable survival period for such claim specified in Section 11.1 or (ii) unless, and only to the extent that, such failure materially adversely affects the Indemnifying Party’s ability to defend against, reduce or eliminate Losses arising out of such claim. After delivery of the Direct Claim Notice, the Parties shall then meet in an attempt to agree upon a resolution of such claim. If the Parties have not resolved any such claim within forty-five (45) days after the date that the Direct Claim Notice is delivered, then any Party shall have the right, subject to any express limitations in this Agreement, to pursue any and all remedies available at law or in equity with respect to such claim. Notwithstanding the foregoing (including the failure of the Parties to agree on a course of action), each Party shall use commercially reasonable efforts to address any claims or liabilities that may provide a basis for an claim as if indemnification did not exist for such claim such that each Party shall respond to any claims or liabilities in the same manner it would respond to such claims or liabilities in the absence of the indemnification provisions of this Agreement.

11.5 Payment.

(a) Upon a determination of liability under this Article XI, the appropriate Party shall pay the Indemnified Party the amount so determined within thirty (30) days after the date of such determination; provided, however, that in the event that the Indemnified Party is Purchaser and such determination of liability arises during the first eighteen (18) months after the Closing Date, Purchaser shall draw such amounts from the Escrow Account, if and to the extent that sufficient funds remain in the Escrow Account, and directly from Sellers only if and to the extent that there are insufficient funds remaining in the Escrow Account at such time to cover

such liability. If there should be a dispute as to the amount or manner of determination of any indemnity obligation owed under this Agreement, the Indemnifying Party shall nevertheless pay when due such portion, if any, of the obligation that is not subject to dispute. The difference, if any, between the amount of the obligation ultimately determined as properly payable under this Agreement and the portion, if any, theretofore paid shall bear interest. Upon the payment in full of any claim, the Indemnifying Party shall be subrogated to the rights of the Indemnified Party against any Person, firm, corporation or other entity with respect to the subject matter of such claim.

(b) If any fact, circumstance or condition forming a basis for a Claim for indemnification under this Article XI shall overlap with any fact, circumstance, condition, agreement or event forming the basis of any other Claim for indemnification under this Article XI, there shall be no duplication in the calculation of the amount of the Losses. Without limitation of the foregoing, Purchaser shall not be entitled to any indemnification for any liability or loss to the extent taken into account in determining OWC pursuant to Section 3.3.

11.6 Duty to Mitigate.

(a) Each Indemnified Party shall use its commercially reasonable efforts to mitigate Losses for which indemnification may be sought pursuant to this Article XI, including (i) using its commercially reasonable efforts to secure payment from insurance arrangements available and existing on the Closing Date that are to provide coverage with respect to such Losses (an “Insurance Payment”), and (ii) using its commercially reasonable efforts to secure reimbursement, indemnity or other payment from any third Person obligated by Contract or otherwise to reimburse, indemnify or pay the Indemnified Party with respect to such Losses. Notwithstanding the foregoing or anything to the contrary in this Agreement: (x) the recovery by an Indemnified Party from any Indemnifying Party shall not relieve the Indemnified Party of its obligation to mitigate Losses pursuant to this Section 11.6; and (y) the obligation to mitigate Losses in accordance with this Section 11.6 shall not delay or suspend the obligations of any Indemnifying Party to pay the Indemnified Party any amounts due under this Article XI.

(b) Any amounts payable to an Indemnified Party with respect to any Losses pursuant to this Article XI shall be reduced by the amount of any Insurance Payment received by the Indemnified Party with respect to such Losses.

(c) Any amounts payable to an Indemnified Party with respect to any Losses pursuant to this Article XI shall be reduced by the amount of any net Tax benefits available to the Indemnified Party as a result of the payment, incurrence or accrual of such Losses.

11.7 Characterization of Indemnification Payments. Unless otherwise required by Law, any indemnification payment pursuant to the provisions of this Article XI shall be considered an adjustment to Purchase Price, and each of the Parties shall prepare all Tax Returns and financial accounting reports in a manner consistent with such characterization.

11.8 No Special Damages. Notwithstanding anything to the contrary contained herein, no Indemnifying Party shall be liable to or otherwise responsible to any

Indemnified Party for consequential, special, incidental, exemplary or punitive damages (other than consequential, special, incidental or punitive damages awarded to a third party pursuant to a Third Party Claim) or for a diminution in value or lost business opportunity that arise out of or relate to this Agreement or the performance or breach hereof or any liability assumed hereunder.

11.9 Materiality Standard. Solely for purposes of this Article XI, if any representation or warranty contained herein, in Sellers’ Certificate or in Purchaser’s Certificate is limited or based upon materiality, including the terms “material”, “materially” or “material adverse effect” (excluding such references in the defined term “Material Contracts” as such term is used in Section 5.6 and such references in Sections 5.11 and 5.13(a)), such limitation or qualification shall in all respects be ignored and given no effect for purposes of determining the amount of any Loss arising from a breach thereof.

11.10 Remedies Exclusive. Notwithstanding anything to the contrary in this Agreement, except with respect to fraud, the remedies provided in this Article XI shall be deemed the sole and exclusive remedies of the Parties, from and after the Closing Date, with respect to the subject matters of the indemnification provisions of this Article XI, and the Parties each hereby waive to the extent permitted by applicable Law any other remedy, to which they or any other Person entitled to indemnification hereunder may have at law or in equity with respect thereto.

MISCELLANEOUS PROVISIONS

12.1 Amendment; Waiver. This Agreement may be modified or amended only by agreement in writing of all of the Parties. Any extension or waiver of any term or condition set forth herein shall be valid only if set forth in an instrument in writing signed by the Party or Parties to be bound thereby. Waiver of any term or condition of this Agreement by a Party shall not be construed as a waiver of any subsequent breach or waiver of the same term or condition by such Party, or a waiver of any other term or condition of this Agreement by such Party. The failure of any Party to assert any of its rights hereunder shall not constitute a waiver of any such rights.

12.2 Entire Agreement. This Agreement, the Ancillary Agreements and the Confidentiality Agreement constitute the entire agreement among the Parties pertaining to the subject matter hereof and supersede all prior agreements and understandings of the parties with respect to the subject matter hereof, written or oral, including the Confidentiality Agreement (but only to the extent provided in Section 7.2).

12.3 Severability. It is the desire and intent of the Parties that the provisions of this Agreement be enforced to the fullest extent permissible under the Law and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, in the event that any provision of this Agreement would be held in any jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision

could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn by either a court of competent jurisdiction or the parties hereto, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

12.4 No Assignment; Parties in Interest. Neither this Agreement nor any rights and obligations hereunder shall be assigned by any Party without the prior written consent of the other Parties. Any attempted assignment in violation of this Section 12.4 shall be null and void and of no force and effect. Subject to the foregoing, all of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to confer upon or give any other Person any rights or remedies of any nature whatsoever under or by reason of this Agreement. Purchaser may assign any or all of its rights, interests and obligations hereunder (including its rights under Article XI) to any Person who is providing debt financing to Purchaser, from time to time as collateral security for such debt financing, but no such assignment shall relieve Purchaser of its obligations hereunder.

limited to matters required by this Agreement to be disclosed in the Seller Disclosure Schedules, and any such additional matters are set forth for informational purposes only and do not necessarily include other matters of a similar nature.

12.11 Time of the Essence. Time is of the essence for each and every provision of this Agreement.

12.12 Limitation of Liability.

12.14 Representation by Counsel. The Parties each acknowledge that each Party has been represented by counsel in connection with this Agreement and the Contemplated Transactions. Accordingly, any rule of Law or any legal decision that would require interpretation of any claimed ambiguities in any portions of this Agreement against the party that drafted it has no application and is expressly waived. If any provision of this Agreement is, in the judgment of the trier of fact, ambiguous or unclear, that provision shall be interpreted in a reasonable manner to effect the intent of the Parties.
