(b) Neither the execution and delivery of this Agreement by the Seller nor the consummation by the Seller of the transactions contemplated by this Agreement nor compliance by the Seller with any of the provisions hereof will (i) conflict with or result in any breach of any provision of the certificate of incorporation or by-laws (or similar organizational documents) of the Company, (ii) require the consent or waiver of any person (other than a Governmental Entity) or result in a violation or breach of, or constitute a default (or with notice or lapse of time or both result in a breach of or constitute a default) under, or give rise to a right of termination, cancellation or acceleration of any obligation under, or the loss of any material benefit under, any Company Contract, or result in the imposition of or the creation of any Lien upon any of the assets or properties of the Company pursuant to or under, any of the terms, conditions or provisions of any note, lease, license, contract or agreement to which the Seller, Company or any of their Affiliates is a party or by which the Seller, Company or any of their Affiliates or any of their respective assets, is bound or (iii) violate any order, writ, injunction, decree, or any statute, law, ordinance, regulation, rule, code, order or other requirement or rule of law (each, a "Law") applicable to the Seller, Company or any of their Affiliates, except in the case of violations, breaches or defaults which, or consents or waivers the absence of which, individually or in the aggregate, have not had and would not have a Company Material Adverse Effect or which would not prevent or materially delay the consummation of the transactions contemplated by this Agreement or which would not prevent or materially affect the ability of Purchaser to conduct the business of the Company. 4 Section 3.4 Financial Statements.

(b) The Seller has not received written notice from any third party regarding any actual or potential infringement by the Company of any intellectual property of such third party and the Seller has no knowledge of any legitimate basis for such a claim against the Company. Section 3.10 Employee Benefit Plans. (a) Section 3.10(a) of the Seller Disclosure Schedule contains a complete list of all employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended ("ERISA")), all employment and severance agreements, and all bonus, stock option, stock purchase, incentive, deferred compensation, supplemental retirement, severance and other similar employee benefit plans, programs, policies and agreements, in each case that are sponsored, maintained, contributed to or required to be contributed to by the Company, or to which the Company is a party for the benefit of any current or former employee, director, consultant or independent contractor of the Company (together, the "Company Employee Plans"). Except as set forth on Section 3.10(a) of the Seller Disclosure Schedule, none of the Company Employee Plans is sponsored, maintained, contributed to or required to be contributed to by Seller (other than the Company) and no current employee, director, consultant or independent contractor of the Seller (other than the Company) participates or is eligible to participate in such Company Employee Plans. (b) The Seller has delivered or made available to the Purchaser accurate and complete copies of the following with respect to the Company Employee Plans, to the extent applicable, as of the date of this Agreement: (i) all plan documents and all amendments thereto, (ii) summary plan descriptions and summaries of material modifications, (iii) trust documents, insurance contracts and other funding instruments, (iv) the two most recently prepared financial statements and actuarial reports, (v) the two most recently filed annual reports and (vi) determination letters received from the Internal Revenue Service.

Each Company Employee Plan that is intended to be qualified under Section 401(a) of the Code has received a current determination letter from the Internal Revenue Service stating that it is so qualified in its entirety, and to the knowledge of Seller each such plan is so qualified, and, as of the date of this Agreement, no such determination letter has been revoked. There have been no "prohibited transactions" within the meaning of Section 6 4975 of the Code or Section 406 of ERISA involving any of the Company Employee Plans that would be reasonably likely to subject the Company to any penalties or taxes.

With respect to those employees who continue employment with the Company after the Closing Date (the "Employees"), Purchaser agrees to provide employee benefits to the Employees that are, in all material respects, no less favorable to such Employees than the employee benefits provided to similarly situated employees of Purchaser (or its Affiliates) under employee benefit plans sponsored by Purchaser provided that such Employees will be subject to the terms and conditions of the applicable employee benefit plan, subject, in all cases, to the provisions of this Section 5.5. However, the Employees shall not be credited with their prior years of service with the Company for purposes of Purchaser's Separation Benefit Plan or Purchaser's Separation Benefit Plan for Senior Management. (b) Purchaser and Seller shall cooperate in making all appropriate arrangements and filings, if any, with respect to the Company's Employee Plans. Seller represents, covenants and agrees with respect to the Company's Plans that are qualified under Section 401(a) of the Code, that, as of the date of Closing,, such plans (i) satisfy the requirements of Sections 401(a), (k), and (m) of the Code and any and all other applicable laws and regulations, (ii) such plans are qualified under the Code and have been amended to satisfy the requirements of the Tax Reform Act of 1986, the Unemployment Compensation Amendments of 1992, the Omnibus Reconciliation Act of 1993, and the final nondiscrimination regulations under Section 401(a)(4) of the Code, and (iii) will have not been amended or operated in a way which would adversely affect such qualified status. (c) The Company shall provide any Employee who is subsequently terminated by the Company for any reason, health plan continuation coverage to the extent of and in accordance with the requirements of the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended, and Section 601 through 608 of ERISA ("COBRA"); and Seller agrees to provide health plan continuation coverage to the extent of and in accordance with COBRA. (d) As soon as possible after execution of this Agreement, Seller will provide Purchaser with copies of each of its employee benefit plans, policies and programs provided to Company's employees associated with the Company Property. 15 Section 5.6 Access to Records. The Purchaser agrees that it shall take reasonable efforts to preserve and keep all books and records in respect of the Company business that relate to periods prior to the Closing, or to matters for which the Seller may be required to provide indemnification hereunder, for a period of four years from the Closing Date (or any longer period required by applicable law or until the final resolution of any matters for which the Seller may be required to provide indemnification hereunder), and shall give the Seller reasonable access to such books and records during normal business hours. However, failure of Purchaser to maintain such records will not result in any liability to the Seller or any of its Affiliates. (b) Subject to applicable law and any applicable contractual restrictions, if following the Closing a party hereto (or its subsidiaries) is in possession of any information relating to the business of the Company which the other party requires in order to prepare documents required to be filed with Governmental Entities or its financial statements, such party shall furnish such information to the other party as soon as reasonably practicable following a written request for such information. Section 5.7 Notice of Possible Breach. Prior to the Closing, if any party to this Agreement shall become aware of any fact, event or circumstance that would constitute a breach of this Agreement by the other party or that would result in the failure to satisfy any condition set forth in Article 6, such party shall promptly notify the other party thereof in writing. The parties shall thereupon provide reasonable cooperation to cure or remedy such breaches or satisfy such closing conditions. Section 5.8 Supplemental Disclosure. From time to time prior to the Closing, the Seller will, and will cause the Company to, promptly following its becoming aware thereof supplement or amend the Seller Disclosure Schedule with respect to any matter hereafter arising or discovered which, if known, existing or occurring at the date of this Agreement, would have been required to be set forth or described in the Seller Disclosure Schedule. From time to time prior to the Closing, the Purchaser will, promptly following its becoming aware thereof supplement or amend the Purchaser Disclosure Schedule with respect to any matter hereafter arising or discovered which, if known, existing or occurring at the date of this Agreement, would have been required to be set forth or described in the Purchaser Disclosure Schedule. Any supplement or amendment of the Seller Disclosure Schedule or the Purchaser Disclosure Schedule made pursuant to this Section 5.8 shall not be deemed to cure any breach or inaccuracy of any representation or warranty made in this Agreement. Section 5.9 Notices of Certain Events. The Seller shall, and shall cause the Company to, notify the Purchaser in writing and the Purchaser shall notify the Seller in writing of: (a) any notice or other communication received by the Seller, the Company or the Purchaser, as the case may be, from any person alleging that the consent of such person is or may be required in connection with the transactions contemplated by this Agreement; (b) any notice or other communication from any Governmental Entity received by the Seller, the Company or the Purchaser, as the case may be, that relates to the transactions contemplated by this Agreement or that is materially significant to the Business; and (c) any actions, suits, claims, investigations or proceedings commenced or, to the Seller's or the Purchaser's, as the case may be, knowledge threatened against, relating to or involving or otherwise affecting the Seller, the Company or the Purchaser, as the case may be, that relate to the consummation of the transactions contemplated by this Agreement. Section 5.10 Confidentiality. From the Closing Date until the third anniversary of the Closing Date, the Seller will not, and will not permit its Affiliates or any of their respective affiliates to, disclose to any person without the prior written consent of the Purchaser any confidential or non-public information relating to or concerning the business of the Company (the "Confidential Information"), unless (i) disclosure is required to be made under applicable Law or (ii) such information is or becomes generally available (a) to the public other than as a result of disclosure by the Seller in violation of this Section 5.10 or (b) to the Seller on a non-confidential basis from a source, other than the Company or the Purchaser, which to the knowledge of the Seller, is not prohibited from disclosing the confidential information by contractual, legal or fiduciary obligation. The Seller shall notify the Purchaser promptly after receipt by the Seller of any request for such information. 16 Section 5.11 Insurance. The Seller shall keep, or cause to be kept, all material insurance policies maintained by the Seller for the benefit of the business of the Company, or suitable replacements therefor (which may include policies containing terms equal or more favorable than the policies that they are replacing), in full force and effect up to the Closing. To the extent the Seller or any of its Affiliates receives, whether before or after the Closing Date, any proceeds from any insurance policy with respect to the business of the Company (except in respect of excluded assets or liabilities for which the Seller is responsible), the Seller shall or shall cause its Affiliates to pay over to the Company such proceeds as promptly as practicable. Section 5.12 Non-Solicitation of Employees. (a) From and after the date hereof, the Seller shall not (and shall cause his Affiliates to not), without the prior written approval of the Purchaser, for a period of two years from the Closing Date, directly or indirectly, solicit, encourage, entice or induce any person who is an employee of the Company at the date hereof or who becomes an employee of the Company after the date hereof but prior to the Closing Date, to terminate his or her employment with the Company, or hire or employ any person who is an employee of the Company at the date hereof or who becomes an employee of the Company after the date hereof but prior to the Closing Date; provided that the foregoing shall not apply to persons who approach the Seller or any of his Affiliates for the purposes of employment or who are hired as a result of the use of an independent employment agency where contact between such person and the independent employment agency was initiated by such person or as a result of the use of a general solicitation (such as an advertisement) not specifically directed to employees of the Company. (b) If it is ever held that the restriction placed on any party to this Agreement by this Section 5.12 is too onerous and is not necessary for the protection of the other party or parties hereto, each party to this Agreement agrees that any court of competent jurisdiction may impose lesser restrictions which such court may consider to be necessary or appropriate to properly protect the other party or parties hereto. Section 5.13 Listing of Purchase Consideration. The Purchaser shall use its reasonable best efforts to cause the shares of Purchaser's common stock to be issued hereunder to be listed on the New York Stock Exchange, subject to official notice of issuance, as promptly as possible. Section 5.14 Nonsolicitation. Prior to the Closing, except with respect to this Agreement, none of the Seller, any Affiliate of the Seller, or Representative of the Seller or any of his Affiliates may directly or indirectly (1) solicit, initiate, encourage or knowingly facilitate (including by way of furnishing information) any inquiries relating to, or the making of, any Acquisition Proposal by any person, or (2) have any discussion with or furnish any confidential information or data to any person relating to an Acquisition Proposal, or engage in any negotiations concerning an Acquisition Proposal, or knowingly facilitate any effort or attempt to make or implement an Acquisition Proposal. The Seller shall, and will cause his Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any parties conducted heretofore with respect to any Acquisition Proposal and Seller will use his reasonable best efforts to cause such parties to return or destroy confidential information concerning the Company provided to such parties by or on behalf of the Seller. The Seller shall promptly inform his Representatives of the obligations undertaken in this Section 5.14. "Acquisition Proposal" means any proposal or offer (whether or not in writing) to acquire in any manner, directly or indirectly, any Company Shares, any shares of capital stock or other securities of the Company or all or any material portion of the assets or properties of Company. "Representative" shall mean any investment banker, financial advisor, attorney, accountant, consultant, or other representative. Section 5.15 Option to Acquire Additional Drilling Rigs. (a) KFOC has certain drilling rig parts and inventory that it currently intends to use to build additional drilling rigs (the "Build-Out Rigs") in the future. In the event KFOC desires to build out the Build-Out Rigs, Seller shall cause KFOC to build out the Build-Out Rigs on the following terms and conditions: (i) The Build-Out Rigs shall be built out in groups ("Groups" and each a "Group"). Each Group shall consist of up to five rigs. KFOC shall notify Purchaser, in writing, when KFOC determines to build out a Group. (ii) Purchaser and KFOC shall negotiate in good faith, for a period not exceeding fifteen Tulsa business days following notice by KFOC of its desire to build-out a Group, to agree on the number of rigs in a Group, the type of rigs (giving preference to using existing KFOC equipment), the design of the rigs, and the time when each 17 Group will be built (the "Group Specifications"). In the event, Purchaser and KFOC do not agree upon the Group Specifications, KFOC shall have the right to determine the Group Specifications in its sole discretion. (iii) At such time as the Group Specifications have been determined in accordance with the preceding subparagraph, KFOC shall provide written notice to Purchaser setting forth the Group Specifications and Seller's proposed sales price for each Build-Our Rig in the Group (the "KFOC Group Notice"). (iv) Purchaser shall have the exclusive first option to elect to acquire the Group at Seller's proposed sales price for the total sales price of all of the Build-out Rigs in the Group, provided such option is irrevocably and unconditionally exercised as to all Build-Out Rigs in the Group by notice to KFOC within 15 days after receipt of the KFOC Group Notice (the "Option"). In the event Purchaser elects to exercise an Option, KFOC shall, if requested by Purchaser, transfer the assets and equipment comprising the Group into a new wholly owned subsidiary of KFOC and Purchaser shall acquire all of the outstanding capital stock of the new subsidiary company as opposed to acquiring the assets comprising the Group. (v) If Purchaser timely exercises the Option in respect of a Group: (A) KFOC shall build-out the Build-Out Rigs in the Group in accordance with the Group Specifications in all material respects. Each Build-Out Rig shall be, when delivered, fit for the purposes for which it is intended. (B) Purchaser shall accept delivery of each Build-Out Rig as completed at the place of build-out within the later of fifteen Tulsa Business days following notice of the completion of such Build-Out Rig or the date on which the Build-Out Rig is in material compliance with the Group Specifications (the "Delivery Date"). The sales price of each Build-Out Rig shall be paid in Purchaser's Common Stock valued as hereafter provided. (C) The value of Purchaser's Common Stock shall be based on the average closing sales price thereof on the New York Stock Exchange for the 15 trading days prior to the KFOC Group Notice. The Common Stock shall be issued and delivered to KFOC on the Delivery Date and, when issued, shall be fully paid and non-assessable. (vi) If Purchaser fails to timely exercise the Option with respect to any Group (a Non-Acquired Group"), KFOC shall be free to (i) sell the Non-Acquired Group to a third party at a price not less than the price originally proposed to Purchaser or (ii) allow one of Seller's Affiliates to work the Build-Out Rigs. In the event of (ii) and Seller or KFOC elects thereafter to sell the Non-Acquired Group (or any individual Build-Out Rig included in the Non-Acquired Group) or if Seller or KFOC should elect to sell the Non-Acquired Group (or any individual Build-Out Rig included in the Non-Acquired Group) to a third party at a price below that originally offered to Purchaser, then Seller must first provide written notice thereof to Purchaser and allow Purchaser the option to acquire such Rig(s) on the terms and conditions heretofore set forth, but at the new sales price. This provision will apply each time that Seller or his Affiliate proposes to sell a Non-Acquired Rig. (vii) At Seller's election and, subject to the negotiation and execution of a management agreement providing for the allocation of responsibilities and obligations, the Build-Out Rigs would be built-out under Purchaser's supervision with KFOC paying the costs to build out the rigs. Purchaser would be entitled to receive a supervision fee of $100,000 per rig. The management agreement shall, in addition to other terms and conditions, include the terms set forth on Section 5.15(a)(vii) of the Seller Disclosure Schedule. Purchaser's obligations under this Section 5.15(a)(vii) shall terminate three years from the Closing Date. (b) Until the earliest to occur of (i) three years from the Closing Date, or (ii) such time as all of the Build-Out Rigs have been built-out in accordance with this Agreement: (i) Seller and his Affiliates shall not engage directly in the onshore contract drilling business except for Non-Acquired Rigs that Purchaser has not purchased and Seller or his Affiliates elected to work in accordance with (a)(v)(ii) above; and, (ii) Seller and his Affiliates (including KFOC) shall not acquire control of any entity engaged in the onshore contract drilling business. For purposes of this subsection, "control" means the acquisition, directly or indirectly, of shares or interests in any class of voting securities of such entity in an amount that is the greater of (i) 18 25% or (ii) an amount equal to that held by any person or group that is not an Affiliate of the Seller. Any shares acquired by Seller pursuant to the sale of a Non-Acquired Group (or any individual Build-Out Rig included in the Non-Acquired Group), in accordance with subsection (vi) above, shall not be included for purposes of determining if Seller has acquired control of any entity. (c) Any shares of Purchaser Common Stock issued to Seller in accordance with the provisions of this Section 5.15 will be subject to the provisions of Article 10. (d) The provisions of this Section shall be subject to enforcement by means of Section 12.6. (e) Any of the parties subject to this Section 5.15, may upon written notice to the other parties assign its rights, interest or obligations under this section to one or more Affiliates: provided, that in any or all such cases the original party hereto shall remain responsible for the performance of its duties, liabilities or obligations under this Section 5.15. Section 5.16 Loss of Company Property. (a) The Seller shall keep, or cause to be kept, all material insurance policies maintained by the Seller for the benefit of the business of the Company, or suitable replacements therefor (which may include policies containing terms equal or more favorable than the policies that they are replacing), in full force and effect up to the Closing. Except as otherwise provided in subsections (b) and (c) below or in respect of a liability for which Seller is liable, to the extent the Seller or any of his Affiliates receives, whether before or after the Closing Date, any proceeds from any insurance policy with respect to the Company Property, the Seller shall or shall cause his Affiliates to pay over to the Company such proceeds as promptly as practicable. (b) If any Company Property shall become an actual or constructive total loss prior to the Closing Date: (i) the Purchase Consideration shall be reduced by the amount allocated to such Company Property pursuant to Section 5.16 of the Seller Disclosure Schedule and the Seller shall be entitled to any insurance proceeds and claims with respect thereto together with all rights to salvage and (ii) the other provisions of this Agreement shall continue to be in effect and the Closing shall take place in the manner contemplated herein. (c) If a Company Property sustains damage (estimated to cost more than $10,000 to repair) not amounting to an actual or constructive total loss prior to the Closing Date, at the Seller's election either (i) the Seller shall repair or cause to be repaired the damage to the Company Property at the Seller's own expense or (ii) elect not to repair such Company Property. In the case of an election under clause (ii) of this subsection, the Purchaser may (x) require the Seller to assign to Purchaser at the Closing the rights, if any, the Seller has to receive insurance proceeds in respect of such loss or damage or (y) elect to have the that part of the Company Property excluded as an asset of the Company and be entitled to a reduction in Purchase Consideration equal to its value as set out in Section 2.1(a) of the Seller's Disclosure Schedule. In the case of either (i) or (ii)(x) above, the Purchase Consideration shall not be reduced. Section 5.17 Financial Statement Information. Either before or after the Closing, Seller agrees to cooperate with Purchaser and to assist Purchaser's outside auditors in the preparation of any financial statements relating to the Company Property or the Company that may be reasonably requested by Purchaser for filing with the Commission in connection with any filings that may be made by Purchaser under the Securities Act or the Exchange Act. Such financial statements may consist of (i) such audited balance sheets and audited statements of operations, cash flows and changes in equity together with the notes thereon and (ii) such unaudited interim balance sheet and unaudited interim statements of operations, cash flows and changes in equity, if any, in each case as Purchaser shall reasonably deem to be required.

Each of the Purchaser and the Seller shall retain, and the Purchaser shall cause the Company to retain, all Tax Records in its possession for all open Tax Periods ending on or before or including the Closing Date, until six months following the expiration of the statute of limitations (and any extensions thereof) of the respective Tax Periods. "Tax Records" means any Tax Return, Tax Return work papers, documentation relating to any Audit, and any other books of account or records (whether on paper, computer disk or any other medium) required to be maintained under the applicable Tax Law or under any record retention agreement with any Tax Authority. Section 8.2 Cooperation. The Purchaser and the Seller covenant and agree that subsequent to the Closing, upon reasonable notice and during normal business hours, they and their Affiliates will (i) give the other party and its representatives information, books and records relevant to the Company to the extent necessary to enable the other party to prepare its Tax Returns and (ii) provide the other party or its Affiliates with such information, books and records as may reasonably be requested in connection with any Tax Return, inquiry, election, audit or other examination by any Tax Authority, or judicial or administrative proceedings relating to liability for Taxes.

Section 8.4 Tax Returns. (a) Consolidated Returns. Seller shall prepare (or cause to be prepared) and timely file all consolidated United States Income Tax Returns (within the meaning of Section 1501 of the Code and the Treasury Regulations promulgated pursuant to Section 1502 of the Code) and all other combined, joint, consolidated or unitary Tax Returns required to be filed with any Tax Authority (collectively the "Consolidated Returns") with respect to the Company for any Tax Period including, or ending on or before, the Closing Date. Payment of Taxes shown to be due on such Consolidated Returns shall be made in accordance with Section 8.6 hereof. In a manner consistent with past custom and practice of Seller and the Company, Purchaser shall timely provide (or cause to be provided) to the Seller all information (including pro forma Tax Returns, schedules, statements and supporting documentation) reasonably required in connection with the preparation and filing of such Consolidated Returns. Seller shall not elect, pursuant to Treasury Regulation Section 1.1502-20(g) or Treasury Regulation Section 1.1502-96(d), or any comparable provision of law or regulations, to reattribute to itself any portion of the net operating loss carryovers, net capital loss carryovers or section 382 limitation, if any, attributable to the Company. Any consolidated section 382 limitation applicable to the Seller and its subsidiaries (including the Company) as of the Closing Date, if any, shall be apportioned between the Seller and its subsidiaries (other than the Company), on the one hand, and the Company, on the other, pursuant to Treasury Regulation Section 1.1502-95 based on the relative fair market value of such entities immediately prior to the Closing Date. Any such allocation shall be proposed by the Seller for approval by the Purchaser, which approval shall not be unreasonably withheld. (b) Separate Company Returns. Seller shall prepare (or cause to be prepared) and timely file all other Tax Returns with respect to the Company that are not Consolidated Returns and that are for Tax Periods ending on or before the Closing Date; provided however, that the filing of any such Tax Return shall, except as set forth on Section 8.4(b) of the Seller Disclosure Schedule, be subject to the Purchaser's prior written consent, which shall not be unreasonably withheld; provided further that the Purchaser shall consent to the filing of any such Tax Return if such filing would not have a significant adverse effect on the Taxes of the Company for any Post-Closing Period. Purchaser shall prepare (or cause to be prepared) and timely file all Tax Returns for any Tax Period ending after the Closing Date that are not Consolidated Returns (the "Purchaser Returns"). If the Seller is obligated under this Agreement to indemnify the Purchaser for any Taxes due with respect to a Purchaser Return, the filing of such Purchaser Return shall be subject to the Seller's prior written consent, which shall not be unreasonably withheld; provided however, that the Seller shall consent to the filing of any such Tax Return if such filing would not have a significant adverse effect on the Taxes of the Company for any Pre-Closing Period. Payment of Taxes shown to be due on such Tax Returns shall be made in accordance with Section 8.5 hereof and shall be allocated among the parties in accordance with Section 8.5(b) hereof. 22 (c) Tax Accounting Practices. Any Tax Return that includes any of the Company's assets or activities for any Pre-Closing Period shall be prepared in accordance with past Tax accounting practices used with respect to the Tax Returns in question (unless the party responsible for preparing the Tax Return determines that the past practices are no longer permissible under the Code or other applicable Tax law), and to the extent any items are not covered by past practices (or in the event such past practices are no longer permissible under the Code or other applicable Tax law), in accordance with reasonable Tax accounting practices selected by the party responsible for preparing the Tax Return. (d) Amendment of Tax Returns. Except as set forth on Schedule 8.4(d) or as required under applicable law, from the date of this Agreement, Seller agrees not to amend any Tax Return attributable to a Pre-Closing Period (as defined in Section 8.5 of this Agreement) without the consent of the Purchaser, such consent not to be unreasonably withheld; provided however, that the Purchaser shall consent to the filing of any amended Tax Return if such filing would not have a significant adverse effect on the Taxes of the Company for any Post-Closing Period. From the Closing Date, Purchaser agrees not to amend any Tax Return attributable to a Pre-Closing Period (as defined in Section 8.6 of this Agreement) without the consent of the Seller, such consent not to be unreasonably withheld; provided however, that the Seller shall consent to the filing of any amended Tax Return if such filing would not have a significant adverse effect on the Taxes of the Company for any Pre-Closing Period. Section 8.5 Allocation of Taxes. (a) Purchaser Return Taxes. From and after the Closing Date, Purchaser shall pay (or cause the Company to pay) to the appropriate Tax Authorities any Taxes due on or after the Closing Date with respect to a Purchaser Return. (b) Allocation of Straddle Period Taxes. Purchaser and Seller shall, to the extent permitted by applicable Tax Law and except as otherwise provided herein, elect with the relevant Tax Authority to close the Tax Period of the Company as of and including the Closing Date. Subject to the preceding sentence, in the case of Taxes attributable to the Company that are payable with respect to any Tax Period beginning before the Closing Date and ending after the Closing Date (a "Straddle Period") the portion of any such Taxes that are allocable to the portion of the Straddle Period ending on the Closing Date shall: (1) in the case of Taxes that are either (A) based upon or related to income or receipts or (B) imposed in connection with any sale, transfer or assignment of property (real or personal, tangible or intangible) be deemed equal to the amount that would be payable if the Tax year ended on and included the Closing Date and (2) in the case of Taxes (other than those described in clause (i)) imposed on a period basis with respect to the business or assets of the Company or otherwise measured by the level of any item, be deemed to be the amount of such Taxes for the entire Straddle Period (or, in the case of such Taxes determined on an arrears basis, the amount of such Taxes for the immediately preceding Tax Period) multiplied by a fraction the numerator of which is the number of calendar days in the portion of the Straddle Period ending on and including the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period (the "Part-Year Fraction"). For purposes of clause (1) of the preceding sentence, any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated to the portion of the Straddle Period ending on the Closing Date on a pro rata basis determined by multiplying the total amount of such item allocated to the Straddle Period times the Part-Year Fraction. In the case of any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, any amount thereof required to be allocated under this Section 8.5(b) shall be computed by reference to the level of such items on the Closing Date. (c) Post-Closing Tax Periods. From and after the Closing Date, for the portion of any Straddle Period that begins on the day after the Closing Date and any other Tax Period beginning after the Closing Date, without duplication of any amount otherwise payable by Purchaser pursuant to this Agreement, Purchaser shall pay, or cause the Company or any subsidiary to pay, to the appropriate Tax Authority any other Taxes due with respect to the Company for any such period. Section 8.6 Tax Indemnity. (a) Seller's Indemnity for Taxes for Pre-Closing Periods. Notwithstanding Article 9, from and after the Closing Date, without duplication of any amount otherwise payable by Seller pursuant to this Agreement, Seller shall indemnify Purchaser and its respective Affiliates against all Taxes imposed on or payable by the Company: (i) with respect to any Tax Period ending on or before the Closing Date and the portion of the Straddle Period ending on the Closing Date (a "Pre-Closing Period"); or 23 (ii) that are attributable to Seller or any member of an affiliated, consolidated, combined or unitary Tax group of which the Company is or was a member prior to the Closing Date that is imposed under Treasury Regulation Section 1.1502-6 (or any similar provision of state, local or foreign law) by reason of such Company being included in any such affiliated, consolidated, combined or unitary Tax group. (b) Seller's Indemnity for Payments Attributable to Pre-Closing Periods. Notwithstanding Article 9, from and after the Closing Date, without duplication of any amount otherwise payable by Seller pursuant to this Agreement, Seller shall indemnify Purchaser and its respective Affiliates against any payments owed by the Company to any third party (other than a Governmental Entity) with respect to Taxes accruing on or before the Closing Date. (c) Purchaser Indemnity for Taxes for Post-Closing Tax Periods. Notwithstanding Article 9, from and after the Closing Date, Purchaser shall indemnify Seller against all Taxes of Purchaser, relating to any Tax Period or portion thereof that begins on or after the Closing Date. (d) Payments. Payment by the indemnitor of any amount due under this Section 8.6 shall be made within 30 days following written notice by the indemnitee that payment of such amounts to the appropriate Tax Authority is due, such written notice to reasonably demonstrate that the indemnitee is entitled to such payment under the terms of this Agreement. If Seller or any of its Affiliates receives an assessment or other notice of Taxes due with respect to the Company for any period for which Seller is not responsible, in whole or in part, pursuant to Section 8.4 hereof, then Purchaser shall pay such Tax, or if Seller pays such Tax, then Purchaser shall pay to Seller the amount of such Tax for which Seller is not responsible. In the case of a Tax that is contested in accordance with the provisions of Section 7.6 hereof, payment of the Tax to the appropriate Tax Authority will not be considered to be due earlier than the date of a final determination to such effect is made by the appropriate Tax Authority or court. (e) Tax Refund. If the Purchaser or any of its subsidiaries (including, for this purpose, the Company after the Closing Date) receives a Tax refund of the Company with respect to a Pre-Closing Period, the Purchaser shall pay (or cause the Company to pay) to the Seller the amount of such Tax refund (net of any costs or expenses incurred by the Purchaser or the Company in obtaining the Tax Refund). Such payment shall be made within 15 days of the receipt of such Tax refund by the Purchaser or any of its subsidiaries. Section 8.7 Contests. (a) Notices. After the Closing Date, Purchaser and Seller each shall notify the other in writing within 5 days of receipt of any notice of the commencement of any Tax audit or administrative or judicial proceeding affecting the Taxes of any of the Company or any of its subsidiaries, which, if determined adversely to the taxpayer, would be grounds for indemnification under this Agreement by the other party (or parties, in the case of Seller) ("Tax Indemnitor"). Such notice shall contain factual information describing any asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any Tax Authority in respect of any such asserted Tax liability. If either Purchaser or Seller fail to give the other party prompt notice of an asserted Tax liability as required under this Agreement, then (i) if the Tax Indemnitor is precluded by the failure to give prompt notice from contesting the asserted Tax liability in any administrative or judicial forums, such party shall not have any obligation to indemnify the other party for any loss or damage arising out of such asserted Tax liability, and (ii) if the Tax Indemnitor is not so precluded from contesting, if such failure to give prompt notice results in a detriment to the Tax Indemnitor, any amount which the Tax Indemnitor is otherwise required to pay pursuant to this Agreement with respect to such liability shall be reduced by the amount of such detriment. (b) Control of Contests Involving Consolidated Returns. In the case of an audit or administrative or judicial proceeding involving any asserted liability for Taxes ("Tax Controversy") with respect to a Consolidated Return for a Pre-Closing Period, Seller shall have the right, at its expense, to control the conduct of such Tax Controversy. (c) Control of Contests Involving Separate Company Returns. In the case of a Tax Controversy with respect to a Tax Return that is not a Consolidated Return and is for a Tax Period ending on or before the Closing Date, Seller shall have the right, at its expense, to control the conduct of such Tax Controversy. In the case of a Tax Controversy involving an asserted liability for Taxes with respect to the Company relating to a Straddle Period, other than a Tax Controversy with respect to a Consolidated Return, Purchaser shall have the right, at its expense, to control the conduct of such Tax Controversy. 24 (d) Post-Closing Periods. Purchaser shall control the defense and settlement of any Tax Controversy involving any asserted liability for Taxes imposed with respect to the Company relating to Tax Periods that begin after the Closing Date. (e) Procedures. If the resolution of any Tax Controversy would be grounds for indemnification under this Agreement (including, for this purpose, as a result of altering the Tax Period in which items of income, gain, loss, deduction or credit are reported) by the party not in control of the conduct of such Tax Controversy (the "Non-Controlling Party") or otherwise adversely affect the Tax liability of the Non-Controlling Party, (i) the party in control of such Tax Controversy (the "Controlling Party") shall keep the Non-Controlling Party fully informed of any proceedings, events, and developments relating to or in connection with such Tax Controversy; (ii) the Non-Controlling Party shall be entitled to receive copies of all correspondence and documents relating to such Tax Controversy; (iii) the Controlling Party shall consult with the Non-Controlling Party and shall not enter into any settlement with respect to any such Tax Controversy without the Non-Controlling Party's prior written consent, such consent not to be unreasonably withheld; and (iv) at its own cost and expense, the Non-Controlling Party shall have the right to participate (but not control) the defense of such Tax Controversy. Section 8.8 Miscellaneous. (a) Character of Payments. Any payment made by the Seller, the Purchaser, or any of their respective subsidiaries (including the Company) under this Article 8 shall constitute an adjustment to the Purchase Consideration for all tax purposes. (b) Interest on Payments. To the extent any payment obligation under this Article 8 is not made on a timely basis (as determined by the relevant provision of this Article 8), the amount due and payable shall bear interest at an annual rate equal to the Interest Rate from the last date such payment would be timely under the relevant provision of this Article 8 to the date of the payment of such amount. (c) Survival of Tax Claims. Notwithstanding any other provision of this Agreement to the contrary, any obligations of the parties pursuant to this Article 8 shall be unconditional and absolute and shall survive until the expiration of the applicable statute of limitations (taking into account any applicable extensions or tollings thereof) relating to the Taxes at issue. Article 9. INDEMNIFICATION Section 9.1 Indemnification by the Seller. Subject to the provisions of Section 12.12, the Seller and KFOC (but only with respect to Section 5.15) hereby agrees to indemnify and hold harmless the Purchaser, the Company and their respective successors and assigns after the Closing Date from and against: (a) any Claims and Damages asserted against or incurred by the Purchaser or the Company and occasioned by, arising out of or resulting from any breach of the representations and warranties of the Seller that are set forth in this Agreement (determined after taking into account any amendments or supplements to the Seller Disclosure Schedule since the date of this Agreement and not less than three days before Closing); (b) any Claims and Damages asserted against or incurred by the Purchaser or the Company and occasioned by, arising out of or resulting from the Seller's failure to perform any of the Seller's obligations for which performance after the Closing is specifically required or contemplated under this Agreement; (c) Any obligation (financial or otherwise), Claim or Damages based upon or arising out of or otherwise in respect of the ownership, maintenance or use of the Company or its assets prior to Closing; (d) any violation by Seller or any of his Affiliates of or default by Seller or any such Affiliate under any Laws, including, without limitation, Environmental Laws, which affects the ownership or operation of the Company, or any remedial obligation under any Environmental Law arising out of or related to the ownership, operation, performance of or the maintenance of the assets of the Company prior to the Closing Date; or (e) any liability arising out of, relating to or resulting from an employment relationship between the Company, Seller and any person. 25 Section 9.2 Indemnification by the Purchaser. The Purchaser hereby agrees to indemnify and hold harmless the Seller, its successors and assigns, after the Closing Date from and against: (a) Any Claims and Damages asserted against or incurred by the Seller and occasioned by, arising out of or resulting from any breach of the representations or warranties of the Purchaser that are set forth or incorporated by reference in this Agreement (determined after taking into account any amendments or supplements to the Seller Disclosure Schedule since the date of this Agreement and not less than three days before Closing); (b) Any Claims and Damages asserted against or incurred by the Seller and occasioned by, arising out of or resulting from the Purchaser's failure to perform any of the Purchaser's obligations for which performance after the Closing is specifically required or contemplated under this Agreement; and (c) Any obligation (financial or otherwise), Claim or Damages based upon or arising out of or otherwise in respect of the Assumed Liabilities. Section 9.3 Notice of Claim. Upon obtaining knowledge of any claim or demand that has given rise to, or could reasonably give rise to, a claim for indemnification hereunder, the party seeking indemnification ("Indemnitee") shall give written notice ("Notice of Claim") of such claim or demand to the other party ("Indemnitor"). Indemnitee shall furnish to Indemnitor in reasonable detail such information as Indemnitee may have with respect to such indemnification claim (including copies of any summons, complaint or other pleading which may have been served on it and any written claim, demand, invoice, billing or other document evidencing or asserting the same). No failure or delay by Indemnitee in the performance of the foregoing shall reduce or otherwise affect the obligation of Indemnitor to indemnify and hold Indemnitee harmless, except to the extent that such failure or delay shall have adversely affected Indemnitor's ability to defend against, settle or satisfy any liability, damage, loss, claim or demand for which such Indemnitee is entitled to indemnification hereunder. The Seller and the Purchaser shall take reasonable actions to mitigate Claims and Damages. Section 9.4 Defense of Third Party Claims. If the claim or demand set forth in the Notice of Claim given by Indemnitee pursuant to Section 9.3 hereof is a claim or demand asserted by a third party, Indemnitor shall have ten (10) business days after the date on which such Notice of Claim is given by the Indemnitee to notify Indemnitee in writing of Indemnitor's election to defend such third party claim or demand on behalf of Indemnitee. If Indemnitor elects to defend such third party claim or demand, Indemnitee shall make available to Indemnitor and its agents and representatives all witnesses, pertinent records, materials and information in the Indemnitee's possession or under the Indemnitee's control as is reasonably required by Indemnitor and shall otherwise cooperate with and assist Indemnitor in the defense of such third party claim in good faith. Indemnitee shall not pay, settle or compromise such third party claim or demand. If Indemnitor elects to defend such third party claim or demand, Indemnitee shall have the right to participate in the defense of such third party claim or demand, at Indemnitee's own expense. In the event, however, that the named parties to the action or proceeding include both Indemnitor and Indemnitee and Indemnitee reasonably determines that representation by counsel to Indemnitor of both Indemnitor and Indemnitee may present such counsel with a conflict of interest, then such Indemnitee may employ separate counsel to represent or defend it in any such action or proceeding and Indemnitor will pay the reasonable fees and disbursements of such counsel. If Indemnitor does not elect to defend such third party claim or demand or does not defend such third party claim or demand in good faith, Indemnitee shall have the right, in addition to any other right or remedy it may have hereunder, at Indemnitor's expense, to defend such third party claim or demand; provided, however, that (a) Indemnitor shall not have any obligation to participate in the defense of, or defend, any such third party claim or demand; and (b) Indemnitee's defense of or its participation in the defense of any such third party claim or demand shall not in any way diminish or lessen the obligations of Indemnitor under the agreements of indemnification set forth in this Article 9. Section 9.5 Payment of Claims. Except for third party claims being defended in good faith, Indemnitor shall satisfy any undisputed obligations hereunder in cash immediately after the date of Notice of Claim is given by Indemnitee. Section 9.6 No Liability of Officers, Directors and Managers. Each of the Purchaser and the Seller acknowledges and agrees that it shall not assert any claims it may have arising from this Agreement against officers, directors, beneficiaries, managers, principals or agents of the other party or any Affiliate of such party. 26 Section 9.7 No Third Party Benefit. The rights to indemnification provided in this Agreement are intended solely for the benefit of the Purchaser, the Seller and the Company and their permitted successors and assigns, and are not intended to and shall not be construed as granting or creating a right to payment or indemnification to any other person. Without limiting the generality of the foregoing, no person providing insurance coverage to any Indemnitee shall have rights, whether of subrogation or otherwise, against the Indemnitor by virtue of this Agreement. Section 9.8 Definition. For purposes of this Article 9, "Claims and Damages" shall mean any and all losses, claims, demands, liabilities, obligations, actions, suits, orders, statutory or regulatory compliance requirements, or proceedings asserted by any third party, person or entity, including but not limited to Governmental Entities, and all damages, costs, expenses, assessments, judgments, recoveries and deficiencies, including interest, penalties, investigatory expenses, consultant's fees, and reasonable attorneys' fees and costs (including, without limitation, costs incurred in enforcing the indemnity), incurred by or awarded against a party for which a party is entitled to indemnification hereunder; provided that Claims and Damages shall expressly exclude punitive, exemplary, special or similar losses or damages. Section 9.9 Exclusive Remedy Subject to those provisions of this Agreement that may be enforced by means of Section 12.6 as well as Sections 8.6 and 12.12, after the Closing the sole and exclusive remedy of any party for any inaccuracy of any representation or warranty, or any breach of any agreement or obligation made in this Agreement, shall be the indemnification contained in this Article 9. Article 10. Registration Rights Section 10.1 Registration of Securities. (a) As used in this Article 10, the following terms have the meanings set forth below: "Disadvantageous Condition" has the meaning set forth in Section 10.1(b)(iii). "Holders" means the Seller or any Person who becomes a holder of Subject Securities after the Closing Date as a result of a No-Sale Transaction. "No-Sale Transaction" means a transfer from a Holder of Subject Securities that does not constitute a "sale" (as such term is understood and defined under the Securities Act), including without limitation a distribution from a Holder that is a corporation, partnership, joint venture, limited liability company, association or trust to the owner of a beneficial interest in such Holder to the extent that such distribution would not constitute a sale under the current rules, regulations, case law and administrative rulings and interpretations by the Commission. "Piggy-back Registration" has the meaning set forth in Section 10.1(g)(i). "Registration Expenses" has the meaning set forth in Section 10.1(e). "Registration Termination Date" means the date which is three and one-half years from the date when the Commission first declares the Shelf Registration Statement effective; provided, however that the Registration Termination Date shall be extended for a period equal to the aggregate period or periods during which the Holders have been precluded from selling any Subject Securities under subparagraph (b) (iii) by reason of receipt of a Suspension Notice. Notwithstanding anything to the contrary, the Registration Termination Date shall occur at such earlier date as the Subject Securities become freely transferable on the public market without any restrictions or limitations pursuant to Rule 144(k) promulgated by the Commission. "Shelf Registration Statement" means a registration statement on Form S-3 filed with the Commission under the Securities Act. "Subject Securities" means the shares of Purchaser Common Stock issued as part of the Purchase Consideration to Seller and any common stock or other security issued or issuable as a dividend or other distribution with respect to, or in exchange for, or upon conversion or in replacement of, any of such Purchaser Common Stock. "Suspension Notice" has the meaning set forth in Section 10.1(b)(iii). 27 (b) (i) If the Closing occurs, as promptly as practicable thereafter, Purchaser will, on one occasion only, prepare and file with the Commission a Shelf Registration Statement for the purpose of registering the resale in the market from time to time of the Subject Securities by Holders or by potential assignees of such Holders to which all or a portion of such Holders' Subject Securities may be transferred in a No-Sale Transaction. (ii) Purchaser will use its Best Efforts to have the Shelf Registration Statement promptly declared effective by the Commission and thereafter to maintain the effectiveness of the Shelf Registration Statement and, subject to subparagraph (iv) below, to maintain such Shelf Registration Statement "current" (as below defined) at all times until the Registration Termination Date. Purchaser shall promptly give written notice to the Holders when the Registration Statement has been declared effective by the Commission and is available for use by Holders for the resale of Subject Securities. The Shelf Registration Statement shall not be considered to be "current" at any time when, by reason of occurrence of any event or by reason of the passage of time, the Shelf Registration Statement does not meet the requirements of Section 10, Section 12(2) or Section 17 of the Securities Act, or the Shelf Registration Statement contains an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading. (iii) If at any time or times after the Shelf Registration Statement is declared effective by the Commission, Purchaser's Board of Directors determines that the offering of Purchaser Common Stock under the Shelf Registration Statement would be significantly disadvantageous to Purchaser's ability to negotiate or complete a material financing, merger, acquisition or other material transaction or event involving Purchaser or its subsidiaries that has not been publicly disclosed or the unavailability of any required financial statements for reasons substantially beyond the control of the Purchaser, (a "Disadvantageous Condition"), Purchaser shall be entitled to either suspend the effectiveness of the Shelf Registration Statement with the Commission or suspend the availability of the Shelf Registration for resales of Subject Securities by Holders, or may take both such actions, and shall promptly notify all Holders thereof by delivery of written notice (a "Suspension Notice"); provided, however, that Purchaser's obligation to maintain the Shelf Registration Statement current under this Section 10.1(b) shall not be suspended by reason of Purchaser's failure to disclose information at a time when public disclosure of such information is required by law. Upon receipt of a Suspension Notice, Holders shall immediately discontinue the use of the Shelf Registration Statement for any purpose until notified by Purchaser that the Shelf Registration Statement is current and available for use by Holders for sales of Subject Securities. Purchaser shall not be entitled to suspend the effectiveness of the Shelf Registration Statement for more than 60 consecutive days or an aggregate of 120 days within any twelve-month period and no subsequent suspension period shall occur unless at least 90 days have elapsed during which Seller can utilize the Registration Statement. As promptly as practicable after the public disclosure of such Disadvantageous Condition or the Purchaser determines that the Disadvantageous Condition no longer exists, Purchaser shall amend or supplement the Shelf Registration Statement to the extent necessary to make the Shelf Registration Statement current, and shall give prompt written notice to all Holders when the Shelf Registration Statement is again available for resales of Subject Securities. (iv) If Purchaser should undertake an underwritten public offering of its shares either after the Shelf Registration Statement has been declared effective or prior to the consummation of the transactions contemplated by this Agreement, Seller and any other Holder shall, upon the request of the managing underwriter of such offering, agree and commit, and Seller does hereby agree and commit (and shall cause any other Holder to agree and commit), that it will not effect any public sale or distribution, directly or indirectly, or make any offer to sell, contract to sell (including without limitation any short sale), grant any option to purchase or otherwise transfer or dispose (including sales pursuant to Rule 144) of any of the Subject Securities during a period of seven days prior to and up to 90 days after the closing of such public offering without the consent of the managing underwriter. This restriction shall not apply to the offer and sale of any Subject Securities which may be covered by the registration statement covering such public offering. (v) Purchaser shall promptly notify all Holders of Subject Securities of, and confirm in writing, the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement or the initiation of any proceedings for that purpose. Purchaser shall use its best efforts to obtain the withdrawal of any order suspending the effectiveness of the Shelf Registration Statement at the earliest possible time. 28 (vi) Purchaser will cause all of the Subject Securities to be listed on each securities exchange on which similar securities issued by Purchaser are then listed no later than the effective date of the Shelf Registration Statement. (c) Purchaser will indemnify and hold harmless each Holder, each of such Holder's officers, directors, partners, or members, as the case may be, and each Person controlling such Holder, with respect to which registration or qualification of Subject Securities has been effected pursuant to this Article 10 against all claims, losses, damages, and liabilities, joint or several (or actions in respect thereof), arising out of or based upon any untrue statement (or alleged untrue statement) of a material fact contained in the Shelf Registration Statement, prospectus, or offering circular, or in any document incorporated by reference in any of the foregoing, or arising out of or based upon any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by Purchaser of any rule or regulation promulgated under the Securities Act applicable to Purchaser and relating to action or inaction required of Purchaser in connection with the Shelf Registration and will promptly reimburse Holder and, each of such Holder's officers, directors, partners, or members, as the case may be, and each Person controlling such Holder, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claims, loss, damage, liability or action; provided, however, that Purchaser will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based upon any untrue statement or omission based upon written information furnished to Purchaser by such Holder specifically for inclusion in any such registration statement, prospectus or offering circular. The obligations of Purchaser under the foregoing indemnity agreement shall survive the completion of the offering of Subject Securities under the Shelf Registration Statement . (d) Each Holder with respect to which registration or qualification of Subject Securities has been effected pursuant to this Article 10 will indemnify and hold harmless Purchaser, each of Purchaser's officers, directors, and each Person controlling Purchaser, against all claims, losses, damages, and liabilities, joint or several (or actions in respect thereof), arising out of or based upon any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, or offering circular, or in any document incorporated by reference in any of the foregoing, or arising out of or based upon any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by such Holder of any rule or regulation promulgated under the Securities Act or Exchange Act applicable to such Holder and relating to action or inaction required of such Holder in connection with any such registration or qualification, and will promptly reimburse Purchaser, each of Purchaser's officers, directors, and each Person controlling Purchaser, for any legal and any other expenses reasonably incurred in connection with investigating or defending any such claims, loss, damage, liability or action; provided, however, that such Holder will not be liable in any such case to the extent that any such claim, loss, damage, liability or expense does not arise out of or is not based upon any untrue statement or omission based upon written information furnished by such Holder specifically for inclusion in any such registration statement, prospectus or offering circular. The obligations of Holders under the foregoing indemnity agreement shall survive the completion of the offering of Subject Securities under any registration statement provided for in this Article 10. Notwithstanding the foregoing, in no event shall any selling Holder be liable for an amount in excess of the proceeds from the sale of the Subject Securities realized by such Holder. (e) All expenses incident to Purchaser's performance of or compliance with this Section 10.1, including, without limitation, all registration and filing fees, fees and expenses of compliance with securities or blue sky laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Subject Securities), rating agency fees, printing expenses, messenger and delivery expenses, internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the fees and expenses incurred in connection with the listing of the securities to be registered on the New York Stock Exchange and all securities exchanges on which similar securities issued by Purchaser are then quoted or listed, the fees and disbursements of counsel for Purchaser and its independent certified public accountants (including the expense of any special audit or comfort letters required by or incident to such performance), securities act liability insurance (if Purchaser elects to obtain such insurance), the fees and expenses of any special experts retained by Purchaser in connection with such registration, and fees and expenses of other persons retained by Purchaser, in connection with each registration hereunder (but not including discounts, commissions, fees or expenses payable to underwriters that are attributable to the Subject Securities offered on behalf of the Selling Holder or the fees and expenses of counsel for any selling Holder) (collectively, the "Registration Expenses") will be borne by Purchaser. 29 (f) Purchaser will also take such action as may be required to be taken under applicable blue sky laws in connection with the issuance of Purchaser Common Stock pursuant to this Agreement and in connection with resale of Subject Securities by Holders pursuant to the Shelf Registration Statement; provided that Purchaser will not be required to become qualified as a foreign corporation in any jurisdiction. (g) (i) If, at any time during the period ending on the fourth anniversary of the date of this Agreement, the Purchaser proposes to file a registration statement under the 1933 Act with respect to an offering by the Purchaser for its own account or for the account of any other Person of any class of equity security, including any security convertible into or exchangeable for any equity security (other than a registration statement on Forms S-4 or S-8 (or their successor forms) or filed in connection with an exchange offer or an offering of securities solely to the Purchaser's existing stockholders, and other than as set forth in (ii) below), then the Purchaser shall in each case give written notice of such proposed filing to the Holders of the Subject Securities at least twenty days before the anticipated filing date, and such notice shall offer such Holders the opportunity to register such number of Subject Securities as each such Holder may request (a "Piggy-back Registration"). The Purchaser shall use reasonable efforts to cause the managing underwriter or underwriters of a proposed underwritten offering to permit the Holders of Subject Securities requested to be included in the registration for such offering to include such securities in such offering on the same terms and conditions as any similar securities of the Purchaser included therein. Notwithstanding the foregoing, if the managing underwriter or underwriters of such offering delivers an opinion to the Holders of Subject Securities that the total amount of securities which they and any other Persons (other than the Purchaser) intend to include in such offering is sufficiently large to materially and adversely affect the success of such offering, then the amount of Subject Securities to be offered in such event shall be allocated first to the Purchaser, and then, to the extent that any additional securities can, in the opinion of such managing underwriter or underwriters, be sold without any such material adverse affect, pro rata among the Holders of Subject Securities on the basis of the number of outstanding shares of Purchaser common stock requested to be included in such registration by each such Holder to the amount recommended by such managing underwriter. (ii) Notwithstanding anything to the contrary contained in this Agreement, the Purchaser shall not be required to include Subject Securities in any registration statement if the proposed registration is (A)a registration of a stock option or other employee incentive compensation or employee benefit plan or of securities issued or issuable pursuant to any such plan, or a registration statement relating to warrants, options or shares of capital stock granted or to be granted or sold primarily to employees, directors or officers of the Purchaser, (B) a registration of securities issued or issuable pursuant to a stockholder reinvestment plan or other similar plan, (C) a registration of securities issued in exchange for any securities or any assets of, or in connection with a merger or consolidation with, an unaffiliated Purchaser, (D) a registration of securities pursuant to a "rights" or other similar plan designed to protect the Purchaser's stockholders from a coercive or other attempt to cause a change in control of the Purchaser, (E) registration of securities filed pursuant to Rule 145 under the 1933 Act or any successor rule, or (F) a registration of preferred stock or securities issued in connection with any debt or preferred stock financing of the Purchaser.
