Subject to the provisions of this Section 2.07, Seller shall cause USP to take commercially reasonable efforts to minimize the amount of the cash held by USP as of the Effective Time.

As a result, and notwithstanding the right and obligation of Seller to minimize cash, Seller will use commercially reasonable efforts to

maintain cash accounts of the Companies in the amount necessary to fund the aggregate amount of the USP Outstanding Check Amounts and the Renown Outstanding Check Amounts.

          (b) Purchaser shall, no later than the end of the fifteen (15) Business Day period beginning on the first Business Day following the Closing Date, deliver to Seller a written statement of the amount of the cash held by USP as of the Effective Time (the “USP Cash Statement”).

In the event the Cash Statement reflects that cash held in accounts of USP is less than the USP Outstanding Check Amount (the “USP Cash Shortfall”), then the amount of the USP Cash Shortfall shall be paid by Seller to Purchaser promptly upon receipt of USP Cash Statement. In the event of any dispute between Seller and Purchaser as to the amount of the USP Excess Cash or USP Cash Shortfall, the Seller and the Purchaser shall attempt to resolve their dispute as to the amount of the USP Excess Cash or USP Cash Shortfall in connection with the adjustment, if applicable, to the Base USP Purchase Price provided for in Section 2.08 hereof and, in the event that the Seller and the Purchaser are not able to agree upon the amount of the USP Excess Cash or USP Cash Shortfall, the determination of the amount of the USP Excess Cash or USP Cash Shortfall shall be submitted to the Independent Accounting Firm for resolution.

          (c) Purchaser shall, no later than the end of the fifteen (15) Business Day period beginning on the first Business Day following the Closing Date, deliver to Seller a written statement of the amount of the cash held by Renown as of the Effective Time (the “Renown Cash Statement”). If the Renown Cash Statement reflects cash held in accounts of Renown in excess of the Renown Outstanding Check Amount (“Renown Excess Cash”), then the Purchaser shall pay to Seller, by wire transfer of immediately available funds, on the date that Purchaser delivers the Renown Cash Statement to Seller, an amount equal to the amount of the Renown Excess Cash. In the event the Renown Cash Statement reflects that cash held in accounts of Renown is less than the Renown Outstanding Check Amount (the “Renown Cash Shortfall”), then the amount of the Renown Cash Shortfall shall be paid by Seller to Purchaser promptly upon receipt of Renown Cash Statement. In the event of any dispute between Seller and Purchaser as to the amount of the Renown Excess Cash or Renown Cash Shortfall, the Seller and the Purchaser shall attempt to resolve their dispute as to the amount of the Renown Excess Cash or Renown Cash Shortfall in connection with the adjustment, if applicable, to the Base Renown Purchase Price provided for in Section 2.08 hereof and, in the event that the Seller and the Purchaser are not able to agree upon the amount of the Renown Excess Cash or Renown Cash Shortfall, the determination of the amount of the Renown Excess Cash or Renown Cash Shortfall shall be submitted to the Independent Accounting Firm for resolution.

Seller shall have the right to either accept or dispute the amounts reflected on the Proposed USP Closing Balance Sheet, including the amount of the USP Net Working Capital as reflected therein, and the right to either accept or dispute the amounts reflected on the Proposed Renown Closing Balance Sheet, including the amount of the Renown Net Working Capital as reflected therein, in each case, by delivering written notice (as applicable, an “Acceptance Notice” or a “Dispute Notice”) to the Purchaser before the expiration of the Objection Period. The Dispute Notice shall identify with reasonable particularity each disputed item on the Proposed USP Closing Balance Sheet and/ or the Proposed Renown Balance Sheet, shall specify the amount of such dispute and shall set forth the general basis for each item in dispute. In the event of any such dispute, Seller and the Purchaser shall attempt in good faith to reconcile their dispute, and any resolution by them as to any disputed items shall be final, binding and conclusive on Seller and the Purchaser. If Seller and the Purchaser are unable to reach a resolution of their differences within thirty (30) days

following the date on which Seller delivers the Dispute Notice to the Purchaser (or such longer period as they may agree in writing), then Seller and the Purchaser shall promptly submit any remaining disputed items to KPMG LLP (the “Independent Accounting Firm”).

The fees and disbursements of the Independent Accounting Firm shall be allocated between the Seller on the one hand and the Purchaser on the other hand in the same proportion that the aggregate dollar amount of the disputed items submitted to the Independent Accounting Firm that is unsuccessfully disputed by the Seller or the Purchaser, as the case may be, bears to the total dollar amount of the disputed items submitted to the Independent Accounting Firm. If Seller delivers a Dispute Notice to the Purchaser before the expiration of the Objection Period, the USP Net Working Capital and the Renown Net Working Capital as of the Effective Time as determined by written agreement of Seller and the Purchaser, or as determined by the Independent Accounting Firm, shall be deemed to be, respectively, the Closing USP Net Working Capital and the Closing Renown Net Working Capital and shall be conclusive and binding on Seller and the Purchaser. In addition, if Seller delivers a Dispute Notice to the Purchaser before the expiration of the Objection Period, the Proposed USP Closing Balance Sheet and the Proposed Renown Closing Balance Sheet, as adjusted, if applicable, to reflect the resolution of the dispute between Seller and the Purchaser (whether such resolution arises as a result of an agreement between Seller and the Purchaser or a determination of the Independent Accounting Firm) shall be deemed to be, respectively, the Closing USP Balance Sheet and the Closing Renown Balance Sheet and such Closing USP Balance Sheet and Closing Renown Balance Sheet shall be conclusive and binding on the Seller and the Purchaser.

          (e) In the event that the Closing USP Net Working Capital as finally determined pursuant to Section 2.06(b) or (d) above is equal to the Established USP Net Working Capital, no adjustment shall be made to the amount of the Base USP Purchase Price payable by the Purchaser pursuant to the terms of Section 2.06 and, accordingly, the USP Purchase Price shall be equal to the Base USP Purchase Price.

USP has not incurred any liability under or arising out of ERISA, the Health Insurance Portability and Accountability Act of 1996 and the Family Medical Leave Act of 1993 and, to the knowledge of Seller, no fact or event exists that would result in such a liability.

Except as set forth on Schedule 3.20(d), each Employee Plan is fully funded to the extent required by applicable Law.

          (e) Except as disclosed on Schedule 3.20(e), neither USP nor Renown has any obligation to provide medical or life insurance coverage (whether or not insured) under any Employee Plan or collective bargaining agreement to any current, retired or former employee, director or consultant, or their beneficiaries or dependents, after retirement or other termination of employment, except as may be required by the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) or applicable state medical benefits continuation Law.

USP has complied in all material respects with the provisions of COBRA, the Health Insurance Portability and Accountability Act of 1996 and the Family Medical Leave Act 1993.

Further, should any matter arise

which could affect the registration or authorization of any Employee Plan, Seller, USP or Renown, as the case may be, shall, in a timely fashion, take all steps required to ensure the registration or authorization is not affected. No event has occurred respecting any Employee Plan which would entitle any Person to cause the wind-up or termination of such Employee Plan in whole or in part. There have been no withdrawals, applications or transfers of assets from any Employee Plan or the trusts or other funding media relating thereto except in accordance with the terms of such Employee Plan, Applicable Law and all applicable agreements.

          (b) From the date of this Agreement through the end of the five (5) year period beginning on the first day following of the Closing: (i) Parent, Seller and their respective Affiliates shall take any and all action as may be necessary to prevent their respective officers and directors from making any disparaging statement, either orally or in writing, regarding Purchaser, USP, Renown (or their successors), the business, products, or services thereof, or any of their respective directors, officers, employees, or agents; and (ii) Purchaser and each Affiliate of Purchaser, including, but not limited to, USP and Renown, shall take any and all action as may be necessary to prevent their respective officers and directors from making any disparaging statement, either orally or in writing, regarding Parent, Seller or any of their Affiliates, the business, products or services of Parent, Seller or any of their respective Affiliates or any of their respective directors, officers, employees or agents of Parent, Seller or any of their respective Affiliates. Notwithstanding the foregoing, the obligations of Purchaser and its Affiliates under Section 5.06(b)(ii) above shall not apply to the business, products, services, officers, directors, employees or agents of any Incidental Competitor which may be acquired by Seller pursuant to Section 5.06(e) hereof.

          (c) (i) The Seller acknowledges that: (A) a material breach of any of the covenants contained in this Section 5.06 would result in material irreparable injury to the Purchaser, USP and/or Renown and each of their respective successors for which there is no adequate remedy at law; (B) it may not be possible to measure damages for such injuries precisely; (C) the Purchaser will be entitled to obtain equitable relief, including, but not limited to, a temporary restraining order and/or a preliminary or permanent injunction restraining the Seller and its Affiliates from engaging in activities prohibited by this Section 5.06, and such

other relief as may be required to specifically enforce any of the covenants in this Section 5.06; and (D) Seller waives the posting of a bond or undertaking as a condition to such relief.

               (ii) The Purchaser acknowledges that: (A) a material breach of any of the covenants of Purchaser contained in Section 5.06(b)(ii) would result in material irreparable injury to the Parent, the Seller and their respective Affiliates for which there is no adequate remedy at law; (B) it may not be possible to measure damages for such injuries precisely; (C) the Parent, the Seller and their respective Affiliates will be entitled to obtain equitable relief, including, but not limited to, a temporary restraining order and/or a preliminary or permanent injunction restraining the Purchaser and its Affiliates from engaging in activities prohibited by Section 5.06(b)(ii), and such other relief as may be required to specifically enforce any of the covenants of the Purchaser contained in Section 5.06(b)(ii); and (D) Purchaser waives the posting of a bond or undertaking as a condition to such relief.

          (d) Seller agrees that this Section 5.06, including the provisions relating to duration, geographical area, and scope, is reasonable and necessary to protect and preserve Purchaser’s, USP’s and Renown’s legitimate business interests and the value of the Shares and of USP and Renown, and to prevent an unfair advantage from being conferred on Seller and is thus integral to this Agreement. If any provision or portion of this Section 5.06 is found by a court of competent jurisdiction to be invalid or unenforceable, any such invalid or unenforceable provision or portion thereof shall be deemed, without further action on the part of the parties hereto, modified, amended or limited to the extent necessary to render the same valid and enforceable. No proceeds or other amount received or receivable under this Agreement by the Seller shall be for granting any restrictive covenant under this Agreement. The Seller and the Purchaser shall duly and timely make and file any elections (including any amended elections) that the Seller or the Purchaser (or an affiliate of the Purchaser) may request, in such form as the Seller or the Purchaser may request, as provided for under section 56.4 of the Canadian Income Tax Act, as it is proposed to be amended on the date of this Agreement, or as it may subsequently be amended, or under analogous provisions of any other income tax legislation.

          (e) Nothing in this Section 5.06 shall preclude or prohibit the Seller or any of its Affiliates from acquiring the stock (or other securities) or assets of any Person which derives less than four percent (4%) of its revenues from the conduct of a Competitive Business (any such business being hereinafter an “Incidental Competitor”); provided that, after any such acquisition, the Seller complies with the remaining provisions of this Section 5.06(e). Notwithstanding the rights of the Seller and its Affiliates to purchase an Incidental Competitor, in no event shall Seller and/or its Affiliates have the right, at any time during the five (5) year period beginning on the first day following the Closing Date, to purchase, by merger, acquisition of stock, acquisition of assets or otherwise, any Person identified in a list of such Persons to be agreed to by Seller and Purchaser on the Closing Date. In the event that the Seller or any of its Affiliates acquires an Incidental Competitor at any time during the five (5) year period beginning on the first day following the Closing Date, the Seller or any Affiliate of the Seller that acquires any such Incidental Competitor shall, promptly, but in no event later than thirty (30) days following the acquisition by Seller or any Affiliate of Seller, provide the Purchaser the exclusive right (subject to the execution by Purchaser and Seller or its Affiliate of a confidentiality and exclusivity agreement containing reasonable and customary terms and conditions for similar purposes (the

“Confidentiality Agreement”)), for a period of ninety (90) days following the execution of the Confidentiality Agreement, to perform a due diligence investigation of the business of the Incidental Competitor for the purpose determining whether or not the Purchaser has any interest in purchasing the Incidental Competitor from Seller or its Affiliate. In connection with the due diligence investigation which Purchaser may determine to undertake, Seller agrees to negotiate in good faith with Purchaser the terms and conditions for the Purchaser to acquire any such Incidental Competitor. In the event that Purchaser and Seller or its Affiliate are unable to agree upon terms for the purchase by Purchaser of the Incidental Competitor within ninety (90) days following the execution of the Confidentiality Agreement, Seller or its Affiliate shall not be prohibited from operating the business of such Incidental Competitor in the ordinary course or from engaging in discussions with any third party other than Purchaser for the sale of the business or assets of the Incidental Competitor. In addition to the exception from the prohibitions of Section 5.06(a)(i) set forth above in this Section 5.06(e), nothing in Section 5.06(a)(i) shall preclude or limit any Person, which, is not an Affiliate of the Seller (whether as of the Closing Date or any time thereafter) from engaging in a Competitive Business from and after the acquisition of the Seller, any Affiliate of Seller or any successor in interest to the Seller or any Affiliate of Seller, by merger, purchase of a majority of the stock or other controlling interest, purchase of substantially all of the assets or other transaction having the same or similar effect as any of the foregoing.

     5.07 Further Action. Each of the parties hereto shall use all reasonable efforts to take, or cause to be taken, all appropriate action, to do or cause to be done all things necessary, proper or advisable under Applicable Law, and to execute and deliver such documents and other papers, each as may be required to carry out the provisions of this Agreement and the Ancillary Agreements and to consummate and make effective the transactions contemplated by this Agreement and the Ancillary Agreements. In connection with the foregoing, Seller shall use commercially reasonable efforts to obtain an assignment from the inventor of U.S. Patent No. 7,134,636, issued November 14, 2006 and entitled “Post Support” (hereinafter the “Post Support Patent”) and shall use commercially reasonable efforts to obtain an assignment of U.S. Patent No. 5,217,317 (hereinafter the “Expired Patent”) from the inventor of the Expired Patent (the “Expired Patent Inventor”). In connection with the efforts of the Seller to obtain the assignment from the inventor of the Post Support Patent, the Purchaser agrees to cause USP to commence and prosecute legal proceedings against the inventor of the Post Support Patent, at the Seller’s sole cost and expense and with counsel selected by Seller and reasonably acceptable to Purchaser, to cause the inventor of the Post Support Patent to comply with his obligation to assign his rights to the Post Support Patent to USP as provided in under his employment agreement with USP. In connection with the efforts of the Seller to obtain assignments to the Expired Patents from the Expired Patent Inventors, the Seller’s obligation shall be to request, in writing, an assignment from the Expired Patent Inventors and Seller shall not be obligated to commence litigation against any of the Expired Patent Inventors or to pay any sum to obtain an assignment from any of the Expired Patent Inventors.

     5.08 Release of Indebtedness. Prior to or on the Closing Date, the Seller shall have (or shall have caused each of USP and Renown to have) fully discharged and paid any and all Indebtedness of USP, Renown or the Business, and at Closing the Seller shall deliver evidence of the foregoing reasonably satisfactory to the Purchaser.

     5.09 Legal Privileges. The Seller and the Purchaser acknowledge and agree that all attorney-client, solicitor-client, work product and other legal privileges that may exist with respect to USP or Renown shall, from and after the Closing Date, be deemed joint privileges of the Seller and the Purchaser. Both the Seller and the Purchaser shall use all commercially reasonable efforts after the Closing Date to preserve all privileges and neither the Seller nor the Purchaser shall knowingly waive any such privilege without the prior written consent of the other party (which consent shall not be unreasonably withheld or delayed).

     5.10 Transition Services. Beginning on the Closing Date, the Seller shall furnish or cause to be furnished to USP and Renown, the transition services identified in Schedule 5.10 for the time period provided in Schedule 5.10 for the purpose of enabling the Purchaser to manage an orderly transition. The specific terms and conditions upon which such transition services shall be provided shall be set forth in a transition services agreement which shall be entered into by the Seller and the Purchaser at the Closing.

     5.11 Preservation of Records. Subject to Section 9.02 hereof (relating to the preservation of Tax records), the Seller and the Purchaser shall preserve and keep the records held by them relating to the business of USP and Renown for a period of seven (7) years from the Closing Date and shall make such records and personnel available to the other as may be reasonably required by such party in connection with, among other things, any insurance claims by, legal proceedings against or governmental investigations of the Seller, Renown, USP or the Purchaser or any of their Affiliates or in order to enable the Seller or the Purchaser to comply with their respective obligations under this Agreement; provided, however, that a Person may dispose of any such records at any time during such period if such Person first provides sixty (60) days prior written notice to the other parties hereto of the intent to so dispose of such records and affords such other parties an opportunity, at their expense, to take possession and control of such records.

     5.12 Employee Benefits. (a) For a period of twelve (12) months from the Closing Date, the Purchaser shall cause Renown to offer and/or maintain employee compensation and benefit plans to Continuing Employees (as defined below) that are substantially comparable in the aggregate to the compensation and benefits (as provided by the Employee Plans, except for any option to invest in Parent stock) provided by Renown to Continuing Employees immediately prior to the Closing.

          (b) For a period of twelve (12) months from the Closing Date, the Purchaser shall cause USP to offer and/or maintain employee compensation and benefit plans to Continuing Employees (as defined below) that are substantially comparable in the aggregate to the compensation and benefits generally provided by Purchaser to its employees immediately prior to the Closing. Notwithstanding the foregoing, any continuing Employees who participate in nonqualified deferred compensation plans sponsored by Seller shall not be eligible to participate in nonqualified deferred compensation plans sponsored by Purchaser.

          (c) After the Closing Date, the Purchaser shall take such actions as are necessary to cause each of USP and Renown to grant to any individuals who were employees of USP and

Renown immediately prior to the Effective Time (“Continuing Employees”) credit for past service for purposes of initial eligibility to participate and vesting under any employee benefit plans established or maintained by the Purchaser, Renown and/or USP for Continuing Employees after the Closing Date, except to the extent that such credit would result in a duplication of benefits with respect to the same period of service.

          (d) After the Closing Date, the Purchaser shall cause each of USP and Renown to take such actions as are necessary to give Continuing Employees credit for their past service for purposes of determining the amounts of sick pay, holiday pay and vacation pay they are eligible to receive under any sick pay, holiday pay and vacation pay policies and programs established or maintained by the Purchaser, Renown and/or USP for Continuing Employees after the Closing Date.

          (e) With respect to each Continuing Employee who is an active participant in a group health plan (as defined in Section 5000(b) of the Code) (a “USP Health Plan”) immediately prior to the Effective Time, after the Effective Time, the Purchaser shall cause USP to take such actions as are necessary to ensure that the group health plan established or maintained by the Purchaser and/or USP after the Effective Time for Continuing Employees shall waive any preexisting condition restrictions and waiting period requirements to the extent that such preexisting condition restrictions and waiting period requirements were waived or satisfied under the applicable USP Health Plan in which such Continuing Employee participated immediately prior to the Effective Time: Purchaser shall not provide credit, for the plan year (of the group health plan established for the Continuing Employees) in which the Closing Date occurs (the “Current Year”), for any co payments or deductible payments made by the Continuing Employee and out of pocket expenditures incurred by the Continuing Employee under the applicable USP Health Plan for the Current Year.

          (f) With respect to former Employees of USP who are receiving COBRA coverage, such COBRA coverage shall continue to be maintained solely by Parent and/or Seller’s group health plan.

          (g) Prior to Closing, USP shall take all action necessary to terminate its participation as a Participating Affiliate in the Gibraltar 401(k) Plan. Upon Closing, Continuing Employees that are participants in the Gibraltar 401(k) Plan shall be treated as participants whose employment has terminated and shall have the right to distribution of their account balances in the Gibraltar 401(k) Plan. Although Continuing Employees shall have the option to rollover a distribution from the Gibraltar 401(k) Plan to the Purchaser’s 401(k) Plan, such rollover option shall not include the right to rollover Gibraltar stock held in the Gibraltar 401(k) Plan. Seller shall communicate such limitation to Continuing Employees when notifying participants who are Continuing Employees in the Gibraltar 401(k) Plan of distribution and rollover rights.

          (h) Nothing in this Section 5.12 or this Agreement shall require the Purchaser to continue to employ any Continuing Employee for any specific length of time.

     5.13 Schedules. Seller reserves the right to update the Schedules attached hereto between the date hereof and the Closing Date to reflect changes in the information contained in

such Schedules attributable to facts, events, actions or occurrences first occurring on or after the date hereof; provided that, nothing herein shall be deemed to limit or otherwise impair the right of the Purchaser to recover for any breaches and/or to terminate this Agreement pursuant to Section 8.01(a) (ii) hereof if, in the reasonable determination of the Purchaser, the information disclosed in any update to the Schedules will have a Material Adverse Effect.

     5.14 Intercompany Accounts and Contracts. Net Intercompany Accounts will be paid or forgiven immediately prior to the Closing Date.

     5.15 Exclusive Dealing. Until the Closing Date or until this Agreement shall have been terminated pursuant to Article 8, Seller shall not (and shall cause each of USP and Renown to refrain from), directly or indirectly, solicit, initiate, encourage, or entertain any inquiries or proposals from, discuss or negotiate with, provide any nonpublic information to, or consider the merits of any inquiries or proposals from any Person (other than Purchaser) relating to any business combination transaction involving Seller, USP or Renown, however structured, including the sale of the business or assets (other than in the Ordinary Course of Business) of USP or Renown, or the Shares, or any merger, consolidation, or similar transaction or arrangement. Seller shall notify Purchaser of any such inquiry or proposal within 24 hours of receipt thereof by any Seller, USP or Renown.

(a) Subject to the provisions of this Section 7.03 and the other Sections of this Article 7, the Purchaser agrees to indemnify, defend and hold the Seller, and its Affiliates, officers, directors, employees, agents, successors and assigns, (each a “Seller Indemnified Party”), harmless from and against any and all Losses incurred or sustained by or imposed upon any of the Seller Indemnified Parties with respect to or by reason of:

               (i) any failure, breach or inaccuracy by the Purchaser of any representations or warranties made by the Purchaser under this Agreement or the Ancillary Agreements or contained in any certificate, document or instrument delivered by the Purchaser hereunder; and

               (ii) any breach, default or lack of performance on the part of the Purchaser of any of its covenants or agreements under this Agreement or the Ancillary Agreements.

          (b) Notwithstanding anything to the contrary in this Agreement, the Seller Indemnified Parties shall not be entitled to indemnification with respect to a claim for indemnification under Section 7.03(a)(i) hereof, unless the Seller has given the Purchaser written notice of such claim, setting forth in reasonable detail the facts and circumstances pertaining thereto as soon as practicable following the discovery of such claim by the Seller Indemnified parties, but only to the extent that, as a result of any such failure to provide notice, the Purchaser can demonstrate that its ability to defend against any Third Party Claim or mitigate the cost to the Purchaser of indemnifying such Seller Indemnified Party has been materially adversely affected; or

          (c) With respect to claims for indemnification under Section 7.03(a)(i) hereof, unless the Seller Indemnified Parties have provided the Purchaser written notice of such claim and in all events prior to the expiration of the Survival Period.

          7.04 Procedures for Indemnification. (a) If any Purchaser Indemnified Party or any Seller Indemnified Party (hereinafter an “Indemnified Party”) shall claim to have suffered a Loss (other than with respect to any claim asserted, demand or other Action by any Person who is not a party to this Agreement (hereinafter a “Third-Party Claim”)) for which indemnification is available under Section 7.02 or 7.03, as the case may be, the Indemnified Party shall notify the party required to provide indemnification (hereinafter an “Indemnifying Party”) in writing of such claim: (i) with respect to claims arising under Section 7.02(a)(i) or Section 7.03(a)(i), within the time periods provided in Section 7.02(b)(ii) or Section 7.03(b), as the case may be; (ii) with respect to a claim under Sections 7.02(a) (ii)-(xii) or 7.03(a)(ii) at any time after the Closing Date (except that the obligation of Seller to indemnify the Purchaser Indemnified Parties with respect to claims under Section 7.02(a)(v) shall expire at the end of the three (3) year period beginning on the first day following the Closing Date with respect to any claims arising under Section 7.02(a)(v) for which written notice has not been delivered by the Purchaser Indemnified

Parties to Seller prior to the end of the three year period beginning on the first day following the Closing Date); and (iii) with respect to a claim under Section 7.02(a)(xiii), at any time prior to the expiration of the four (4) year period beginning on the first day following the Closing Date. The written notice to be deilvered shall describe the nature of such claim, the facts and circumstances that give rise to such claim and the amount of such claim if reasonably ascertainable at the time such claim is made (or if not then reasonably ascertainable, the maximum amount of such claim reasonably estimated by the Indemnified Party). In the event that within thirty (30) days after the receipt by the Indemnifying Party of such a written notice from the Indemnified Party, the Indemnified Party shall not have received from the Indemnifying Party a written objection to such claim, such claim shall be conclusively presumed and considered to have been assented to and approved by the Indemnifying Party following receipt by the Indemnifying Party of a written notice from the Indemnified Party to such effect.

          (b) If within the thirty (30) day period described in Section 7.04(a) above, the Indemnified Party shall have received from the Indemnifying Party a written notice setting forth the Indemnifying Party’s objections to such claim and the Indemnifying Party’s reasons for such objection, then the parties shall negotiate in good faith for a period of ten (10) Business Days from the date the Indemnified Party receives such objection. After such ten (10) Business Day period (or such longer period as they may agree in writing), if the parties still cannot agree on the claim, the Indemnified Party may, at any time thereafter, until the expiration of the applicable statute of limitations with respect to its claim for indemnification, commence legal proceedings against the Indemnifying Party to enforce its rights to indemnification from and against any Losses described in the written notice described in Section 7.04(a) above.

     7.05 Additional Limits on Rights to Indemnification. (a) Notwithstanding anything to the contrary in this Agreement, except as provided in Section 7.05(b) , an Indemnified Party shall not be entitled to indemnification:

               (i) for any Losses under Section 7.02(a)(i) or Section 7.03(a)(i), as the case may be, as to which the Indemnified Parties otherwise may be entitled to indemnification hereunder (without giving effect to this clause (i)), until such indemnifiable Losses exceed $400,000 (the “Basket Amount”), provided that, after the aggregate amount of all indemnifiable Losses exceeds the Basket Amount the Indemnifying Party shall be obligated to indemnify the Indemnified Party only to the extent that the aggregate amount of all such Losses exceeds the Basket Amount; and

               (ii) for any Losses under Section 7.02(a)(i) or Section 7.03(a)(i), as the case may be, as to which the Indemnified Parties otherwise may be entitled to indemnification hereunder to the extent that the aggregate amount of such Losses exceeds an amount equal to Six Million Dollars ($6,000,000).

          (b) Notwithstanding the provisions of Section 7.05(a) , the Purchaser Indemnified Parties shall be entitled to be indemnified by the Seller for Losses without reference to or the application of the limitations in Section 7.05(a) if and to the extent that such Losses are attributable to a breach or inaccuracy of the Specified Representations or any of the representations and warranties of the Seller, Renown and USP contained in Section 3.18 hereof.

In addition, notwithstanding the provisions of Section 7.05(a), the Losses which the Purchaser Indemnified Parties shall be entitled to be indemnified by the Seller from and against arising from a breach of the representations and warranties of Sections 3.05(b) and 3.06 shall not be subject to the limitation contained in Section 7.05(a)(i) relating to losses which do not exceed the Basket Amount but shall be subject to the limitation contained in Section 7.05(a)(ii) relating to Losses which exceed the Cap. For the avoidance of doubt, the limitations contained in Section 7.05(a) shall not apply to claims made pursuant to Sections 7.02(a)(ii) through and including 7.02(a)(xii) or to claims made pursuant to Section 7.03(a)(ii).

          (c) An Indemnified Party shall not be entitled to double recovery for any Losses. Without limitation of the foregoing, an Indemnified Party shall not be entitled to indemnification for Losses (and the amount of any such Losses shall not be includable in determining whether the aggregate amount of the Losses exceeds the Basket Amount) if and to the extent that the amount of any Losses from any matter have been taken into account in the determination of the Closing Net Working Capital.

          (d) Solely with respect to indemnification claims arising under Section 7.02(a)(i) or Section 7.03(a)(i)Any payment made by an Indemnifying Party to an Indemnified Party shall be net of any insurance proceeds to which the Indemnified Party is entitled as a result of any such claim. Notwithstanding the foregoing, an Indemnified Party shall not be obligated to commence litigation against any insurance company to collect any insurance proceeds with respect to a claim for which indemnification is available to the Indemnified Party and, in the event that the Indemnified Party commences litigation to collect insurance proceeds from any such insurance company, the time for making a claim for indemnification with respect to the matter for which the Indemnified Party has commenced litigation against an insurance company shall be extended by a period equal to the period beginning on the date the Indemnified party commences litigation against an insurance company to collect upon any claim for which indemnification would otherwise be available under this Article 7 and ending on the date the litigation is finally determined, including the exhaustion of all appeals.

     7.06 Procedures for Third-Party Claims. (a) Any Indemnified Party seeking indemnification pursuant to this Article 7 in respect of any Third-Party Claim shall give the Indemnifying Party from whom indemnification with respect to such claim is sought: (i) prompt written notice of such Third Party Claim (but in no event more than ten (10) days after the Indemnified Party receives written demand of any Third Party Claim which is filed with any Governmental Authority for which there is a limited time period in which to respond); and (ii) copies of all documents and information relating to any such Third-Party Claim within ten (10) days of their being obtained by the Indemnified Party; provided, that the failure by the Indemnified Party to so notify or provide copies to the Indemnifying Party shall not relieve the Indemnifying Party from any liability to the Indemnified Party for any liability hereunder except to the extent that such failure shall have prejudiced the defense of such Third-Party Claim.

          (b) The Indemnifying Party shall have thirty (30) days (or such lesser time as may be necessary to comply with statutory response requirements for litigation claims that are included in any Third-Party Claim) from receipt of the notice contemplated in Section 7.06(a) to notify the Indemnified Party whether or not the Indemnifying Party will, at its sole cost and

expense, defend the Indemnified Party against such claim. If the Indemnifying Party timely gives notice that it intends to defend the Third-Party Claim, it shall have the right, except as hereafter provided, to defend against, negotiate, settle or otherwise deal with the Third-Party Claim and to be represented by counsel of its own choice, and the Indemnified Party will not admit any liability with respect thereto or settle, compromise, pay or discharge the same without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed, so long as the Indemnifying Party is contesting or defending the same with reasonable diligence and in good faith; provided, that the Indemnified Party may participate in any proceeding with counsel of its choice and at its expense; provided further, that the Indemnifying Party may not enter into a settlement of any such Third-Party Claim without the consent of the Indemnified Party, which consent shall be not unreasonably withheld, unless such settlement requires no more than a monetary payment for which the Indemnified Party is fully indemnified by the Indemnifying Party or involves other matters not binding upon the Indemnified Party; and provided further that, in the event the Indemnifying Party does not agree in writing to accept the defense of, and assume all responsibility for, such Third-Party Claim as provided above in this Section 7.06(b) , then the Indemnified Party shall have the right to defend against, negotiate, settle or otherwise deal with the Third-Party Claim in such manner as the Indemnified Party deems appropriate, in its sole discretion, and the Indemnified Party shall be entitled to indemnification therefor from the Indemnifying Party to the extent provided under this Article 7. Notwithstanding the foregoing, In the event that an Indemnified Party makes a claim for indemnification from the Indemnifying Party against any Taxes and the Indemnified Party has provided the Indemnifying Party timely notice of the claim (and, in the case of a claim involving a Tax arising in connection with a Tax audit, has given timely notice of the audit to the Indemnifying Party as required by Section 9.03 hereof), the right of the Indemnifying Party to defend against, negotiate, settle or otherwise deal with the claim relating to Taxes and be represented by counsel of its own choice shall be be conditioned upon the Indemnifying Party first unconditionally acknowledging to the Indemnified Party that the Indemnifying Party is required, to pay any contested Taxes when required by Applicable law (including, for greater certainty, any Taxes required to be paid pending the final determination of the amount of such contested Taxes. Notwithstanding the foregoing, if in the reasonable opinion of the Indemnified Party such Third-Party Claim, or the litigation or resolution of such Third-Party Claim, involves an issue or matter that could have a Material Adverse Effect on the Indemnified Party, including the administration of Tax Returns of the Indemnified Party or a dispute with a significant supplier or customer of the Indemnified Party, or there is a conflict of interest in the defense of such action between the Indemnified Party and the Indemnifying Party, the Indemnified Party shall have the right to control the defense or settlement of any such claim or demand and its reasonable costs and expenses shall be included as part of the indemnification obligations of the Indemnifying Party. If the Indemnified Party elects to exercise such right, the Indemnifying Party shall have the right to participate in, but not control, the defense or settlement of such claim at its sole cost and expense.

          (d) by either the Purchaser or the Seller, effective upon written notice, in the event that any Governmental Authority shall have issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement; or

     8.03 Waiver. Any extension or waiver of the requirements hereunder shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition, of

this Agreement. The failure of any party to assert any of its rights hereunder shall not constitute a waiver of any of such rights.

Environmental Matters

None, except for the following recognized environmental concerns (“RECs”):

	1.		The potential for contamination related to the former outdoor paint operations and solvent storage at the Largo, Florida property (11910 62nd Street North). No information is available from with respect to releases that may have occurred from the former painting operations, thus, the potential for adverse impact to the Site from historic operations of the former painting operations could not be evaluated.
	2.		There is potential for contamination related to the fact that the Livermore, California (2150 Kittyhawk Road) property is listed in the LUST database as having a release from the former gasoline underground storage tank (“UST”) located on the property and because no documentation regarding tank decommissioning or LUST investigation is available.
	3.		The former 2,000-gallon Fuel Oil UST removed on June 3, 1990, the former 1,000-gallon Fuel Oil UST Removed August 17, 1989, and the former 1,000-gallon Fuel Oil UST Removed August 21, 1989, all formerly located at the Montgomery, Minnesota property (703 Rogers Drive). These USTs are considered RECs based on the potential age of the UST before removal and the lack of soil and groundwater quality data.

Labor Matters

USP and Renown had one termination within the last 90 days, but there have been no company initiated terminations in the last 90 days:

Termination Date		Location		Employee		Reason
12/17/2010		Toronto		Stanislav Kashlyunov		Voluntary Retirement

The below employees were laid off in July of 2010. Pursuant to USP policy, when hourly employees are laid off, they stay on layoff status for six months in case we want to call them back from layoff. Their term date in the system will say July 2010 because we have to enter a term date for them to receive COBRA paperwork. However, they were not actually terminated until January 2011 as a result of USP not calling any of the below people back from layoff status.

Termination Date		Location		Employee		Reason
7/12/2010		NJ		Anne DiBlasi		Layoff
