On May 16, 2006, Range Resources Corporation (“Range”) filed a Current Report on Form 8-K (the “Form 8-K”) to report that it had entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated May 10, 2006, by and among Range, Range Acquisition Texas, Inc. and Stroud Energy, Inc., and certain other related agreements. This amendment to the Form 8-K is being filed to include the Merger Agreement and the other agreements described therein as exhibits. The Form 8-K as amended is set forth in full below.

Item 1.01 Entry Into a Material Definitive Agreement.

Merger Agreement

On May 11, 2006, Range Resources Corporation (“Range”) and Stroud Energy, Inc. (“Stroud”) announced that they had entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated May 10, 2006, by and among Range, Range Acquisition Texas, Inc., a newly formed wholly-owned subsidiary of Range (“Merger Sub”), and Stroud (“Stroud”), whereby Merger Sub will merge with and into Stroud, with Stroud surviving the merger as a wholly-owned subsidiary of Range (the “Merger”).

Under the Merger Agreement, each share of Stroud common stock issued and outstanding immediately prior to the effective time of the Merger (other than shares for which the holder thereof has perfected appraisal rights under Delaware law) will be converted into and exchanged for the right to receive from Range, subject to valid elections by Stroud stockholders and subject to the allocation and adjustment provisions of the Merger Agreement:

•

a fractional share of Range common stock (the “Stock Consideration”) equal to:

	o		.909 shares of Range common stock, if the average closing price of a share of Range common stock on the New York Stock Exchange for the fifteen consecutive trading days ending at the close of trading on the fifth trading day before the closing of the Merger (the “average closing price”) is less than $22.00;

	o		between .909 and .815 shares of Range common stock, if the average closing price of a share of Range common stock is equal to or greater than $22.00 and less than or equal to $24.53;

	o		.815 shares of Range common stock, if the average closing price of a share of Range common stock is equal to or greater than $24.54 and less than or equal to $30.67;

	o		between .815 and .753 shares of Range common stock, if the average closing price of a share of Range common stock is equal to or greater than $30.68 and less than or equal to $33.21; or

	o		.753 shares of Range common stock, if the average closing price of a share of Range common stock is greater than $33.21; or

	•		an amount in cash equal to the applicable Stock Consideration multiplied by the average closing price of a share of Range common stock (the “Cash Consideration”); or

	•		a fraction of a share of Range common stock equal to 50% of the applicable Stock Consideration and an amount in cash equal to 50% of the Cash Consideration (the “Mixed Consideration”).

Only holders of Stroud common stock that Range has determined are eligible under applicable securities laws to receive shares of Range common stock as merger consideration may elect to receive the Stock Consideration or Mixed Consideration.

Stroud, on the one hand, and Range and Merger Sub on the other, have made customary representations, warranties, covenants and agreements in the Merger Agreement.

Stroud has agreed that its board of directors will recommend that its stockholders approve the Merger Agreement and the Merger and, with certain exceptions, not to directly or indirectly solicit, encourage or facilitate proposals relating to alternative business combination transactions. However, the board of directors of Stroud may, subject to payment of the termination fee described below, change its recommendation in favor of the Merger in certain circumstances, including upon a good faith determination by the board of directors of Stroud, after consultation with and receipt of advice from its outside legal counsel, that such change in recommendation is required to comply with its fiduciary duties under applicable law.

The Merger Agreement is subject to termination by either Range or Stroud for various reasons, including but not limited to: the mutual written consent of Range and Stroud; the failure of the Stroud stockholders to approve the Merger (provided that Stroud cannot terminate for this reason if Stroud’s failure to fulfill any covenant or agreement under the Merger Agreement caused such failure); or if the Merger shall have not been consummated by August 1, 2006. Range may terminate the Merger Agreement if, among other reasons, Stroud’s board of directors changes its recommendation that the Stroud stockholders approve the Merger Agreement and the Merger or if a material adverse effect occurs with respect to Stroud. Stroud may terminate the Merger Agreement if, among other reasons, a material adverse effect occurs with respect to Range or Stroud accepts a proposal for an alternative business combination transaction that, after consultation with and the receipt of advice from its legal counsel and financial advisor, the board of directors of Stroud has determined is superior, from a financial point of view, to Stroud’s stockholders and Range elects not to adjust its offer to be as favorable to Stroud’s stockholders from a financial point of view as the alternative proposal. Upon a termination of the Merger Agreement pursuant to certain sections of the Merger Agreement, including if Stroud’s board of directors changes its recommendation that the Stroud stockholders approve the Merger or elects to accept a superior proposal, Stroud shall be obligated to pay a termination fee to Range in an amount up to 3% of the aggregate merger consideration.

At the effective time of the Merger, all options to purchase shares of Stroud common stock outstanding at the effective time of the Merger, whether vested or unvested, shall be assumed by Range and converted into options to purchase shares of Range common stock at an exchange ratio calculated in the same manner as the Stock Consideration.

Consummation of the Merger is subject to various closing conditions, including, among others, the requisite approval by Stroud’s stockholders and the effectiveness of a Non-Competition Agreement with Patrick J. Noyes, the President and Chief Executive Officer of Stroud, entered into by Range and Mr. Noyes in connection with the Merger Agreement, which restricts his ability to participate in the oil and gas industry in Denton, Wise, Parker, Tarrant, Johnson, Ellis and Hood Counties, Texas, for a period of one year following the effective time of the Merger, as well as other customary closing conditions. In addition, Stroud entered into an amendment to its shareholder rights agreement in order to facilitate the proposed Merger.

The foregoing description of the Merger Agreement is qualified in its entirety by reference to the Merger Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 1.01.

Registration Rights Agreement

In connection with the Merger Agreement, Range entered into a Registration Rights Agreement with Stroud, to take effect upon the effective time of the Merger, for the benefit of the Stroud stockholders receiving Range common stock in connection with the Merger. Pursuant to this agreement, Range has agreed to file, on or prior to the second business day following the effective time of the Merger, an automatically effective resale shelf registration statement to register resales of the shares of Range common stock issued in the Merger and to maintain the effectiveness of such registration statement for a maximum of one year after the effective time. Range also has agreed to file post-effective amendments or prospectus supplements to the registration statement to name all eligible holders under the Registration Rights Agreement as selling stockholders therein and include in the registration statement all registrable securities issued to or known to be issuable to such holder. Range, however, is not obligated to file a post-effective amendment or prospectus supplement solely for the purpose of adding holders of registrable securities more often than once each calendar week during the first four calendar weeks following the effective time of the Merger and thereafter no more than once in each calendar month.

Range may suspend the use of any resale shelf registration statement for up to 45 days in any 90-day period, or 90 days in any 12-month period, upon the occurrence of an event or upon discussions relating to, or the consummation of, a transaction that Range determines in good faith would (i) require additional disclosure of material information by Range in the shelf registration statement, (ii) as to which Range has a bona fide business purpose for preserving confidentiality or (iii) that renders Range unable to comply with Securities and Exchange Commission requirements.

The foregoing description of the Registration Rights Agreement is qualified in its entirety by reference to the Registration Rights Agreement, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 1.01.

Stockholder Voting Agreements

In connection with the Merger Agreement and as a condition to Range entering into the Merger Agreement, Range has entered into stock voting agreements with each of Patrick J. Noyes, Stephen M. Clark, G. Christopher Veeder, David B. Miller, Christopher A. Wright, Samuel J. Atkins, Dan M. Krausse, Philip S. Smith, Gregory D.

Frazier, Chris Hammack and Gregory P. Smith. As of the execution of the Merger Agreement, these Stroud stockholders beneficially owned an aggregate of 2,287,280 shares of Stroud common stock, collectively representing 14.1% of the Stroud common shares outstanding on that date.

Under the stock voting agreements, each of the stockholders has agreed, among other things, to vote his shares of Stroud common stock in favor of the approval of the Merger Agreement and the Merger, and all actions in furtherance thereof, and against any other action that is intended or could reasonably be expected to impede, interfere with, delay, postpone or adversely affect in any material respect the Merger and the other transactions contemplated by the Merger Agreement. The stock voting agreements expire upon the earlier of the termination of the Merger Agreement or the effective time of the Merger.

The foregoing description of the stock voting agreements is qualified in its entirety by reference to the form of stock voting agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 1.01.

Item 8.01 Other Events.

On May 11, 2006, Range issued a press release announcing the execution of the Merger Agreement, a copy of which is filed as Exhibit 99.1 hereto and incorporated herein by reference.

(b) The directors of Merger Sub shall, from and after the Effective Time, be the directors of the Surviving Corporation, and such directors shall serve until their successors have been duly elected or appointed and qualified or until their death, resignation or removal in accordance with Surviving Corporation's Certificate of Incorporation and Bylaws.

Immediately following the Effective Time, Parent shall cause the Surviving Corporation to merge with and into LLC Sub, with LLC Sub continuing as the surviving entity in such merger as a direct wholly-owned subsidiary of Parent, substantially 3

in accordance with the terms of the merger agreement attached hereto as Exhibit F. There shall be no condition to the completion of the LLC Sub Merger other than the completion of the Merger. From and after such merger, LLC Sub shall be the Surviving Corporation for purposes of this Agreement.

ARTICLE II EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE COMPANY AND MERGER SUB; EXCHANGE OF CERTIFICATES 2.1 Effect of Merger on Capital Stock. At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or any holder of any shares of common stock, par value $0.001 per share, of the Company ("Company Common Stock") or capital stock of Merger Sub: (a) Conversion of Capital Stock of Merger Sub. Each issued and outstanding share of the capital stock of Merger Sub shall be converted into one share of Company Common Stock. (b) Conversion of Company Common Stock. Subject to Section 2.1(f), each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (excluding shares held by any Subsidiary of the Company, Parent or any Subsidiary of Parent, and excluding Appraisal Shares (as defined below), but including shares of Company Restricted Stock issued and outstanding immediately prior to the Effective Time) (the "Company Closing Shares") shall cease to be outstanding and shall be converted into and exchanged for the right to receive from Parent, subject to causes (w), (x), (y) and (z) of this Section 2.1(b) below, to the extent applicable: (i) subject to elections by holders of Company Closing Shares to receive Parent Common Stock in accordance with Section 2.1(b)(ii) and Section 2.1(b)(iii), an amount in cash (the "Per Share Cash Value") equal to the product obtained by multiplying the Exchange Ratio by the Average Closing Price; or (ii) upon the valid election of a holder of Company Closing Shares to receive Parent Common Stock in accordance herewith: (A) 0.909 of a share of common stock, par value $0.01 per share, of Parent ("Parent Common Stock") if the Average Closing Price (as defined below) is less than $22.00 per share, or (B) that fraction of a share of Parent Common Stock (rounded to the third nearest decimal place) equal to the quotient obtained by dividing $20.00 by the Average Closing Price, if the Average Closing Price is greater than or equal to $22.00 per share and less than or equal to $24.53 per share, or 4

(C) 0.815 of a share of Parent Common Stock if the Average Closing Price is greater than or equal to $24.54 per share and less than or equal to $30.67 per share, or (D) that fraction of a share of Parent Common Stock (rounded to the third nearest decimal place) equal to the quotient obtained by dividing $25.00 by the Average Closing Price, if the Average Closing Price is greater than or equal $30.68 and less than or equal to $33.21, or (E) 0.753 of a share of Parent Common Stock if the Average Closing Price is greater than $33.21 (such applicable fraction of a share of Parent Common Stock, as it may be adjusted pursuant to Section 2.1(c), the "Exchange Ratio"); or (iii) upon the valid election of a holder of Company Closing Shares in accordance herewith to receive cash and Parent Common Stock, (A) an amount in cash equal to the product of (1) 0.50 multiplied (2) by the Per Share Cash Value and (B) a fraction of a share of Parent Common Stock equal to the product of (1) 0.50 multiplied by (2) the Exchange Ratio. The consideration described in clause (i) above of this Section 2.1(b) is referred to herein as the "Cash Consideration," the consideration described in clause (ii) above of this Section 2.1(b) is referred to herein as the "Stock Consideration," the consideration described in clause (iii) above of this Section 2.1(b) is referred to herein as the "Mixed Consideration," and the Stock Consideration, the Cash Consideration, the Mixed Consideration and the cash to be paid in lieu of fractional shares pursuant to Section 2.6 is collectively referred to herein as the "Merger Consideration." Notwithstanding the foregoing provisions of this Section 2.1(b): (w) in order to receive Stock Consideration or Mixed Consideration, a holder of Company Closing Shares must be an Eligible Holder and must make a valid Election pursuant to and in accordance with Section 2.1(e) (holders that make a valid Election to receive Mixed Consideration being referred to herein as the "Mixed Consideration Holders," and holders that make a valid Election to receive Stock Consideration being separately referred to herein as "Stock Consideration Holders"); (x) subject to the following clause (y), all holders of Company Closing Shares that are not Mixed Consideration Holders or Stock Consideration Holders, including as a result of the failure to return properly completed and executed Eligible Holder Election Materials prior to the Election Deadline, will receive Cash Consideration in exchange for their shares of Company Common Stock in the Merger (such holders being referred to herein as the "Cash Consideration Holders"); (y) notwithstanding the foregoing clause (x), if there is a Stock Consideration Shortfall, then each Company Closing Share held by a Cash Consideration Holder that (1) holds, in the aggregate, more than 1% of the Company Closing Shares, (2) held such shares as of the record date for the Stockholders' Meeting and continuously held such shares from such record date to the Effective Time, and (3) properly completed and returned an Investor Questionnaire and Election Form certifying that it was an "accredited investor" and satisfies the 5

investor suitability standards set forth therein at any time after the delivery to the Exchange Agent of such holder's Investor Questionnaire and Election Form or, if no Investor Questionnaire and Election Form is delivered, at the discretion of Parent, after receipt of the Stockholder Approval (provided Parent shall have no obligation to accept any Investor Questionnaire and Election Form from any such holder after receipt of the Stockholder Approval and may elect to accept such Investor Questionnaire and Election Form after receipt of the Stockholder Approval from one or more Cash Consideration Holders without any obligation to accept such Investor Questionnaire and Election Form from other Cash Consideration Holders) (an "Accredited Cash Elector") shall, notwithstanding the Accredited Cash Elector's election to receive the Cash Consideration, be converted into and exchanged for the right to receive from Parent the Adjusted Per Share Stock Amount and the Adjusted Per Share Cash Amount; provided further that: (A) if the number of shares of Parent Common Stock allocated to Cash Consideration Holders pursuant to this clause (y) (but not taking into account this subclause (A) or subclause (B) of this clause (y)) is not otherwise sufficient to eliminate the Stock Consideration Shortfall, and removing the requirement that an Accredited Cash Elector hold, in the aggregate, more than 1% of the Company Closing Shares would cause a sufficient number of shares of Parent Common Stock to be allocated to Cash Consideration Holders to eliminate the Stock Consideration Shortfall (either by itself or together with the further adjustment contemplated by subclause (B) below of this clause (y)), then the requirement in subclause (1) of this clause (y) shall not apply in order for a Cash Consideration Holder to be deemed an Accredited Cash Elector; (B) if the number of shares of Parent Common Stock allocated to Cash Consideration Holders pursuant to this clause (y) (taking into account subclause (A) above of this clause (y) but not taking into account this subclause (B)) is not otherwise sufficient to eliminate the Stock Consideration Shortfall, then the number of additional shares of Parent Common Stock necessary to be issued as Merger Consideration in order to eliminate the Stock Consideration Shortfall shall be allocated on a pro-rata basis to every Company Closing Share held by an Accredited Cash Elector (taking into account subclause (A) of this clause (y)) and Mixed Consideration Holder (in the case of Accredited Cash Electors, such number shall be in addition to the Adjusted Per Share Stock Amount and, in the case of Mixed Consideration Holders, such number shall be in addition to the Parent Common Stock component of such Mixed Consideration, provided that in no event shall a fraction of a share of Parent Common Stock in excess of the Exchange Ratio be issued in exchange for each Company Closing Share in the Merger), and the amount of cash to be issued in exchange for any such Company Closing Share shall be an amount equal to the difference of (1) the Per Share Cash Value, minus (2) the product of the fraction of a share of Parent Common Stock to be issued in exchange for such Company Closing Share pursuant to this clause (y) multiplied by the Average Closing Price; and (C) notwithstanding the foregoing provisions of this clause (y), if the number of shares of Parent Common Stock that would otherwise be allocated to Accredited Cash Electors and Mixed Consideration Holders pursuant to this clause (y), taking into account subclauses (A) and (B) above of this clause (y), is not sufficient to eliminate the Stock Consideration Shortfall (which, for purposes of this subclause (C), shall be calculated on the basis that the Required Stock Consideration Amount equals the Stock Consideration Tax Amount), then none of the provisions of this clause (y) shall apply. 6

(z) in the event that the Exchange Ratio exceeds 0.815, and the Elected Stock Consideration Amount represents more than 90% of the Total Merger Consideration Value, then, if Parent so elects, in its sole discretion, each Company Closing Share held by a Stock Consideration Holder shall, notwithstanding such Stock Consideration Holder's election to receive Stock Consideration, be converted into and exchanged for the right to receive from Parent the Parent Optional Cash Payout Amount and the Parent Optional Stock Amount. As used herein, the following terms have the meanings given below: "Adjusted Stock Amount" means a number of shares of Parent Common Stock equal to the quotient of (A) the Stock Consideration Shortfall, divided by (B) the Average Closing Price. "Adjusted Per Share Cash Amount" means an amount in cash equal to the difference of (A) the Per Share Cash Value, minus (B) the product of (1) the Adjusted Per Share Stock Amount multiplied by (2) the Average Closing Price. "Adjusted Per Share Stock Amount" means a fraction of a share of Parent Common Stock equal to the quotient of (A) the Adjusted Stock Amount, divided by (B) the total number of Company Closing Shares that are held by Accredited Cash Electors; provided that, in no event shall the Adjusted Per Share Stock Amount exceed an amount equal to the product of (1) 0.50 multiplied by (2) the Exchange Ratio. "Average Closing Price" means the average (rounded to the nearest second decimal place) of the daily closing prices for the shares of Parent Common Stock for the fifteen consecutive full trading days on which such shares are actually traded on the New York Stock Exchange (the "NYSE") (as reported in The Wall Street Journal or, if not reported thereby, any other authoritative source selected by Parent) ending at the close of trading on the fifth trading day prior to the Closing Date. "Company Restricted Stock" means any award of restricted Company Common Stock outstanding as of immediately prior to the Effective Time that shall not have previously expired or terminated, to a current or former employee, director or independent contractor of the Company or any of the Subsidiaries of the Company or any predecessor thereof pursuant to any applicable Company Stock Plan or any other contract or agreement entered into by the Company or any of the Subsidiaries of the Company. "Elected Stock Consideration Amount" means an amount in dollars equal to the product of (A) the sum of (1) the total number of Company Closing Shares with respect to which a valid Election to receive Stock Consideration has been made, plus (2) an amount equal to the product of (x) 0.50 multiplied by (y) the total number of Company Closing Shares with respect to which a valid Election to receive Mixed Consideration has been made, multiplied by (B) the Per Share Cash Value. "Parent Optional Cash Payout Amount" means an amount in cash equal to the quotient of (A) an amount, as determined by Parent in its sole discretion, equal to up to the excess of (1) 10% of the Total Merger Consideration Value over (2) the amount of cash to be paid as Cash Consideration pursuant to Section 2.1(b)(i) and pursuant to valid Elections to receive Mixed Consideration (in each case without giving affect to Section 2.1(b)(z)), and in respect of 7

Appraisal Shares (assuming for purposes of this definition that each Appraisal Share is converted into an amount in cash equal to the Per Share Cash Value), divided by (B) the number of Company Closing Shares that are held by Stock Consideration Holders; provided that, if the sum of (1) the Parent Optional Cash Payout Amount and (2) the product of the Parent Optional Stock Amount multiplied by the Average Closing Price, does not equal the Per Share Cash Value, then the Parent Optional Cash Payout Amount shall be adjusted such that the sum of (1) the Parent Optional Cash Payout Amount and (2) the product of the Parent Optional Stock Amount multiplied by the Average Closing Price shall equal the Per Share Cash Value. "Parent Optional Stock Amount" means a fraction of a share of Parent Common Stock equal to the quotient of (A) the difference of (1) the Per Share Cash Value minus (2) the Parent Optional Cash Payout Amount (prior to any adjustment as provided in the definition thereof), divided by (B) the Average Closing Price. "Required Stock Consideration Amount" means an amount in dollars equal to the greater of the Stock Consideration Minimum Amount and the Stock Consideration Tax Amount; provided that, in the event that the Stock Consideration Minimum Amount exceeds the Stock Consideration Tax Amount, then Parent may, in its sole discretion, deem the Required Stock Consideration Amount to equal any amount that is equal to or greater than the Stock Consideration Tax Amount but that is less than the Stock Consideration Minimum Amount. "Stock Consideration Shortfall" means the amount by which the Required Stock Consideration Amount exceeds the Elected Stock Consideration Amount (provided that, if the Elected Stock Consideration Amount exceeds the Required Stock Consideration Amount, then no Stock Consideration Shortfall shall be deemed to exist). "Stock Consideration Minimum Amount" means an amount in dollars equal to the product of (A) 0.50 multiplied by (B) the Total Merger Consideration Value. "Stock Consideration Tax Amount" means an amount in dollars equal to the product of (A) the Average Closing Price, multiplied by (B) the number of shares of Parent Common Stock that are required to be paid as Merger Consideration in order for the Merger and the LLC Sub Merger to satisfy the continuity of interest requirement under Treasury Regulation Section 1.368-1(e), as reasonably determined in good faith by the Company by the Closing, with such determination being subject to the approval of Parent, which shall not be unreasonably withheld. "Total Merger Consideration Value" means an amount in dollars equal to the product of (A) the sum of (1) the total number of Company Closing Shares plus (2) the total number of Appraisal Shares, multiplied by (B) the Per Share Cash Value. (c) Excess Expense Adjustment; Capitalization Adjustment. (i) If, as of immediately prior to the Effective Time, there shall be outstanding any capital stock of the Company other than a number of shares of Company Common Stock equal to or less than the sum of (A) 16,174,189, plus (B) 848,424 less the number of shares of Company Common Stock subject to then outstanding options or awards under the Company's 2005 Incentive Plan that were issued and outstanding as of the date of this Agreement and set forth on Schedule 3.1(b) of the Company Disclosure Schedule, plus (C) 500, 8

then, at the option of Parent, in its sole discretion, the Exchange Ratio shall be adjusted to equal that fraction (rounded to the nearest third decimal place) of a share of Parent Common Stock equal to the quotient of (1) the Adjusted Per Share Cash Value, divided by (2) the Average Closing Price. "Adjusted Per Share Cash Value" means the quotient of (x) the Total Merger Consideration Value (calculated for these purposes as if the number of shares of Company Closing Shares equals the sum of the amounts in subclauses (A) and (B) of this clause (i), and without taking into account any adjustment to the Exchange Ratio required by this clause (i) or clauses (ii) or (iii) of this clause (c)), divided by (y) the total number of Company Closing Shares. (ii) If, as of immediately prior to the Effective Time, there shall be any shares of Company Common Stock subject to issuance under options, awards or other instruments that were not outstanding as of the date of this Agreement and set forth on Schedule 3.1(b) of the Company Disclosure Schedule (the "Excess Options"), then, at the option of Parent, in its sole discretion, the Exchange Ratio shall be adjusted to equal that fraction (rounded to the nearest third decimal place) of a share of Parent Common Stock equal to the quotient of (A) the Excess Option Payout Share Amount, divided by (B) the total number of Company Closing Shares. "Excess Option Payout Share Amount" means an amount (rounded to the nearest second decimal place) equal to the quotient of (1) the difference of (x) the Total Merger Consideration Value (with the calculation of such amount to take into account any adjustment to the Exchange Ratio required by clause (i) of this clause (c) but not any adjustment to the Exchange Ratio required by this clause (ii) or clause (iii) of this clause (c)), minus (y) the Excess Option Payout, divided by (2) the Average Closing Price. "Excess Option Payout" means an amount equal to the difference of (1) the product of (x) the total number of Excess Options, multiplied by (y) Per Share Cash Value, minus (2) the aggregate exercise price for all of the Excess Options. (iii) In the event that the Company incurs out-of-pocket expenses in excess of $500,000 between the date of this Agreement and the Effective Time in connection with, relating to, or as a result of, any Acquisition Proposal (such excess amount, the "Excess Expense Amount"), then the Exchange Ratio shall be adjusted to equal that fraction (rounded to the nearest third decimal place) of a share of Parent Common Stock equal to the quotient of (A) the Expense Adjusted Share Amount, divided by (B) the total number of Company Closing Shares. "Expense Adjusted Share Amount" means an amount (rounded to the nearest second decimal place) equal to the quotient of (1) the difference of (x) the Total Merger Consideration Value (with the calculation of such amount to take into account any adjustment to the Exchange Ratio required by clause (i) and clause (ii) of this Section 2.1(c) but not any adjustment to the Exchange Ratio required by this clause (iii)) minus (B) the Excess Expense Amount, divided by (B) the Average Closing Price. (d) Proxy Materials. The Company shall mail with the Proxy Statement to each person who is a holder of record of Company Common Stock on the record date for the Stockholders' Meeting: (i) a proxy card pursuant to which holders of Company Common Stock shall indicate whether they authorize the proxies designated therein to vote in favor of the approval of the Merger and this Agreement at the Stockholders' Meeting (a "Proxy Card"), 9

(ii) with respect to holders of Company Common Stock whom Parent has determined in good faith may be offered and sold Parent Common Stock in exchange for their shares of Company Common Stock pursuant to an exemption from registration under the U.S. federal securities laws pursuant to Regulation D promulgated under the Securities Act of 1933, as amended (the "Securities Act"), and applicable state securities laws or, in the case of non-U.S. holders of Company Common Stock, pursuant to regulations promulgated under the Securities Act and applicable securities laws of foreign jurisdictions ("Eligible Holders"): (A) an investor questionnaire and election form substantially in the form attached hereto as Exhibit G (with such modifications thereto as are reasonably agreed upon by Parent and the Company) pursuant to which each Eligible Holder shall be able to elect to receive Stock Consideration, Cash Consideration or Mixed Consideration (an "Election"), and regardless of the type of Merger Consideration chosen, shall make certain representations regarding investor suitability and related matters set forth therein (an "Investor Questionnaire and Election Form"), (B) appropriate transmittal materials and instructions for the surrender of Certificates and the transfer of Uncertificated Shares, in each case to be effective as of the Effective Time (which shall specify that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or irrevocable instructions to transfer the Uncertificated Shares to the Exchange Agent), (C) a selling securityholder questionnaire to be used in compiling information for the registration statement to be filed by Parent pursuant to the Registration Rights Agreement, (D) a joinder to the Registration Rights Agreement pursuant to which such holder agrees to be bound by the terms and conditions of the Registration Rights Agreement, (E) a certificate of nonforeign status meeting the requirements of Treasury Regulation Section 1.1445-2(b)(2) (a "FIRPTA Affidavit") and (F) an IRS Form W-9 (in the case of a U.S. person) or appropriate IRS Form W-8 (in the case of a non-U.S. person), or applicable substitute thereof, or instructions regarding where to obtain such forms (the materials described in clauses (i) and (ii)(A) through (ii)(F) collectively, the "Eligible Holder Election Materials"), and (iii) with respect to holders of Company Common Stock that are not Eligible Holders: (A) appropriate transmittal materials and instructions for the surrender of Certificates and the transfer of Uncertificated Shares (which shall specify that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates or irrevocable instructions to transfer the Eligible Holders Uncertificated Shares to the Exchange Agent), (B) a FIRPTA Affidavit, 10

(C) an IRS Form W-9 (in the case of a U.S. person) or appropriate IRS Form W-8 (in the case of a non-U.S. person), or applicable substitute thereof, or instructions regarding where to obtain such forms (the materials described in clauses (i) and (iii)(A) through (iii)(C) collectively, the "Non-Eligible Holder Election Materials," and together with the Eligible Holder Election Materials, the "Election Materials"). (e) Elections. For a record holder of Company Closing Shares to effect a valid Election to receive the Mixed Consideration or the Stock Consideration, such holder must: (i) be an Eligible Holder, (ii) have held such shares as of the record date for the Stockholders' Meeting, (iii) have held such shares continuously from the record date to the Effective Time, and (iv) have properly completed, signed and delivered to the Exchange Agent by the close of business on the last business day prior to the date on which the Stockholders' Meeting is held (the "Election Deadline") the Eligible Holder Election Materials with an election to receive Stock Consideration or Mixed Consideration, as applicable, in the Investor Questionnaire and Election Form. Parent will have the discretion, which it may delegate in whole or in part to the Exchange Agent, to determine whether Election Materials have been properly completed, signed and submitted and to disregard immaterial defects in Election Materials. The decision of Parent (or the Exchange Agent) in such matters shall be conclusive and binding. Neither Parent nor the Exchange Agent will be under any obligation to notify any person of any defect in Election Materials submitted to the Exchange Agent. If an Eligible Holder's Eligible Holder Election Materials are not properly completed, signed and timely submitted and such defect is not waived by Parent, then a purported Election to receive Stock Consideration or Mixed Consideration therein shall be deemed to be of no force and effect and an Election to receive Cash Consideration shall be deemed to have been made with respect to the shares of Company Common Stock subject to such defective Eligible Holder Election Materials; provided, however, that, if Parent determines in its sole discretion (either prior to or after the Election Deadline) to contact any Eligible Holder that submitted defective Eligible Holder Election Materials (such that a purported Election therein to receive Stock Consideration or Mixed Consideration is invalid) in order cause such defective Eligible Holder Election Materials to be corrected, then the Company shall cooperate with Parent in contacting any such holder and, if any such defective Eligible Holder Election Materials are cured to the satisfaction of Parent in its sole discretion, then such Eligible Holder shall be deemed to have made a valid Election to receive Stock Consideration or Mixed Consideration, as applicable; and provided further that, if Parent determines in its sole discretion (either prior to or after the Election Deadline) to contact any Eligible Holder that submitted an Election to receive Cash Consideration, then the Company shall cooperate with Parent in contacting any such holder and, if any such holder replaces its previous Election with an Election to receive Stock Consideration or Mixed Consideration, then such Eligible Holder shall be deemed to have made a valid Election to receive Stock 11

Consideration or Mixed Consideration, as applicable. Each holder shall make the same Election with respect to all of such holder's shares of Company Common Stock. All Certificates so surrendered and all Uncertificated Shares subject to irrevocable instructions to transfer shall be subject to the exchange procedures set forth in Section 2.7. The Exchange Agent shall also make all computations contemplated by this Section 2.1 and all such computations shall be conclusive and binding on the holders of Company Common Stock absent manifest error. In the case of shares that are certificated, the Exchange Agent shall not accept guarantee of delivery of Certificates in lieu of physical delivery of Certificates. An Election may not be revoked, provided that Parent, in its sole discretion, may permit (i) an Election by an Eligible Holder to receive Cash Consideration to be revoked in exchange for an election to receive Stock Consideration or Mixed Consideration and (ii) an Election by an Eligible Holder to receive Mixed Consideration to be revoked in exchange for an Election to receive Stock Consideration. In the event that this Agreement is terminated pursuant to the provisions hereof and any Certificates have been transmitted to the Exchange Agent pursuant to the provisions hereof, such Certificates shall be promptly returned without charge to the person submitting same and any irrevocable instructions to transfer, in the case of Uncertificated Shares, shall be deemed null and void. (f) Rounding Principles. (i) To the extent any calculation provided for in this Section 2.1 results in fractional numbers, then except as otherwise expressly provided for in this Section 2.1 and in Section 2.1(f)(ii), (A) all fractional dollar or cash amounts shall be rounded to the nearest three decimal places and (B) all fractional share amounts shall be rounded to the nearest four decimal places. (ii) To determine the amount of cash or the number of shares of Parent Common Stock that a holder of Company Closing Shares is entitled to receive with respect to such holder's Company Closing Shares pursuant to Section 2.1(b), the following rounding principles shall apply: (A) the amount of cash each holder of Company Closing Shares shall be entitled to receive pursuant to Section 2.1(b)(i) shall be determined by aggregating the Per Share Cash Value for all Company Closing Shares held by such holder and rounding such aggregate amount to the nearest second decimal place; (B) the number of shares of Parent Common Stock each holder of Company Closing Shares shall be entitled to receive pursuant to Section 2.1(b)(ii) shall be determined by aggregating the fractional shares of Parent Common Stock for all Company Closing Shares held by such holder and rounding such aggregate amount to the nearest third decimal place; (C) the amount of cash each holder of Company Closing Shares shall be entitled to receive pursuant to Section 2.1(b)(iii) shall be determined by aggregating the cash amount determined pursuant to Section 2.1(b)(iii)(A) for all Company Closing Shares held by such holder and rounding such aggregate amount to the nearest second decimal place, and the number of shares of Parent Common Stock such holder of Company Closing Shares shall be 12

entitled to receive pursuant to Section 2.1(b)(iii)(B) shall be determined by aggregating the fractional amount determined pursuant to Section 2.1(b)(iii)(B) for all Company Closing Shares held by such holder and rounding such aggregate amount to the nearest third decimal place; and (D) the amount of cash each Accredited Cash Elector or Mixed Consideration Holder is entitled to receive pursuant to clause (y) of Section 2.1(b) shall be determined by aggregating the cash amount to be issued for all Company Closing Shares held by such Accredited Cash Elector or Mixed Consideration Holder and rounding such aggregate amount to the nearest second decimal place and the number of shares of Parent Common Stock to be received by each Accredited Cash Elector or Mixed Consideration Holder pursuant to clause (y) shall be determined by aggregating the shares of Parent Common Stock to be received for all Company Closing Shares held by such Accredited Cash Elector or Mixed Consideration Holder and rounding such aggregate amount to the nearest third decimal place. 2.2 Anti-Dilution Provisions. (a) In the event that Parent changes the number of shares of Parent Common Stock issued and outstanding prior to the Effective Time as a result of a stock split, stock combination, stock dividend, or similar recapitalization with respect to such stock and if the record date therefor (in the case of a stock dividend) or the effective date thereof (in the case of a stock split, stock combination or similar recapitalization for which a record date is not established) shall be prior to the Effective Time, the Exchange Ratio shall be appropriately adjusted. (b) In the event that, prior to the Effective Time, Parent shall consummate a merger, consolidation, share exchange or other reorganization, or any other transaction with another person or entity pursuant to which the holders of Parent Common Stock receive or become entitled to receive securities, cash or other assets or any combination thereof, each holder of Company Closing Shares subject to a valid Election to receive Stock Consideration or Mixed Consideration shall be entitled to receive at the Effective Time for each Company Closing Share that would otherwise be converted into and exchanged for the right to receive Parent Common Stock, the amount of securities, cash or other assets that such holder would have received or become entitled to receive had such holder been the record holder of the number of shares of Parent Common Stock issuable to such holder of Company Common Stock pursuant to Section 2.1 had the Effective Time occurred immediately prior to the consummation of such transaction. 2.3 Shares Held by Parent, the Company or Subsidiaries. Each of the shares of Company Common Stock held by Parent or any Subsidiary of Parent or the Company or any Subsidiary of the Company shall be canceled and retired at the Effective Time and no consideration shall be issued in exchange therefor. 2.4 Appraisal Shares. Shares of Company Common Stock issued and outstanding immediately prior to the Effective Time that are held by any holder who has not voted in favor of the approval of this Agreement and the Merger and is entitled to demand and properly demands appraisal of such shares pursuant to, and who complies in all respects with, the provisions of Section 262 of the DGCL ("Section 262") shall not be converted into the right to receive the 13

Merger Consideration payable pursuant to Section 2.1(b), but instead such holder shall be entitled to payment of the fair value of such shares (the "Appraisal Shares") in accordance with the provisions of Section 262. At the Effective Time, all Appraisal Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of Appraisal Shares shall cease to have any rights with respect thereto, except the right to receive the fair value of such Appraisal Shares in accordance with the provisions of Section 262. Notwithstanding the foregoing, if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262 or if a court of competent jurisdiction shall determine that such holder is not entitled to the relief provided by Section 262, then the right of such holder to be paid the fair value of such holder's Appraisal Shares under Section 262 shall cease and each of such Appraisal Shares shall be deemed to have been converted at the Effective Time into, and shall have become, the right to receive the Cash Consideration with respect to such shares (without regard to Section 2.1(b)(y)). The Company shall deliver prompt notice to Parent of any demands for appraisal of any shares of Company Common Stock, any withdrawal of such a demand for appraisal and any other instrument delivered to the Company pursuant to Section 262, and Parent shall have the right to participate in and direct all negotiations and proceedings with respect to such demands. Prior to the Effective Time, the Company shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands, or agree to do any of the foregoing. 2.5 Treatment of Stock Options and Restricted Stock. Each outstanding Company Option and share of Company Restricted Stock shall be treated as provided in Section 5.6. 2.6 Fractional Shares. (a) No Fractional Shares. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of the Certificates and the Uncertificated Shares, no dividend or distribution of Parent shall relate to such fractional share interests, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a stockholder of Parent. (b) In lieu of such fractional share interests, Parent shall either (i) pay to each former holder of Company Common Stock an amount in cash equal to the product obtained by multiplying (A) the fractional share interest to which such former holder (after taking into account all shares of Company Common Stock held at the Effective Time by such holder) would otherwise be entitled by (B) the Average Closing Price or (ii) instruct the Exchange Agent to follow the procedures set forth in Section 2.6(c). (c) If Parent shall have instructed the Exchange Agent to follow the procedures in this Section 2.6(c): (i) The Exchange Agent shall determine the excess of (A) the aggregate number of shares of Parent Common Stock that would be distributed to holders of the Certificates and the Uncertificated Shares pursuant to Section 2.1 if no effect were given to Section 2.6(a) over (B) the aggregate number of whole shares of Parent Common Stock to be distributed to holders of the Certificates and the Uncertificated Shares pursuant to Section 2.1, taking into account the effect of Section 2.6(a) (such excess, the "Excess Shares"). 14

(ii) As soon as practicable after the Effective Time, the Exchange Agent shall sell the Excess Shares at then-prevailing prices on the NYSE, in the manner set forth below. (iii) The sale of the Excess Shares by the Exchange Agent shall be executed on the NYSE and shall be executed in round lots to the extent practicable. Parent shall pay all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent, incurred in connection with such sale of the Excess Shares. Until the proceeds of such sale or sales have been distributed to the holders of the Certificates and the Uncertificated Shares (or paid to Parent pursuant to Section 2.7(f)), the Exchange Agent shall hold such proceeds in trust for the holders of the Certificates and the Uncertificated Shares (the "Common Stock Trust"). The Exchange Agent shall determine the portion of the Common Stock Trust to which each holder of a Certificate or an Uncertificated Share shall be entitled, if any, by multiplying the amount of the aggregate net proceeds comprising the Common Stock Trust by a fraction, the numerator of which is the amount of the fractional share interest in the Parent Common Stock to which such holder of a Certificate or an Uncertificated Share is entitled and the denominator of which is the aggregate amount of fractional share interests in the Parent Common Stock to which all holders of the Certificates and the Uncertificated Shares are entitled. Parent shall comply with the provisions of Rule 236(c) under the Securities Act. (iv) As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Certificates and the Uncertificated Shares in lieu of any fractional share interests, the Exchange Agent shall make available such amounts, without interest, to such holders of Certificates that have surrendered their Certificates or Uncertificated Shares, as the case may be, in accordance with Section 2.7. 2.7 Exchange of Certificates. (a) As of the Effective Time, Parent shall deposit with Parent's transfer agent or such other bank or trust company designated by Parent and reasonably acceptable to the Company (provided that the Company agrees that Parent's transfer agent, Computershare Shareholder Services, Inc., is acceptable to the Company) (the "Exchange Agent") the Merger Consideration to be issued and paid in respect of certificates representing Company Closing Shares (the "Certificates") and uncertificated Company Closing Shares ("Uncertificated Shares") (the "Exchange Fund"); provided that in the event the number of shares of Parent Common Stock or the amount of cash to be delivered to a holder of Company Closing Shares as of the Effective Time shall be adjusted after the Effective Time pursuant to the provisions of this Article II, then such number of shares of Parent Common Stock and/or cash, as applicable, shall be delivered to the Exchange Agent promptly upon the determination of any such adjustment. From time to time as necessary, Parent shall deposit with the Exchange Agent cash to be paid in lieu of fractional shares as contemplated by Section 2.6 and any dividends or other distributions to which holders of Company Closing Shares are entitled pursuant to Section 2.7(d). The Exchange Fund shall not be used for any other purpose. As soon as reasonably practicable after the Effective Time but in no event later than five business days thereafter, Parent and the Surviving Corporation shall cause the Exchange Agent to mail to each Cash Consideration Holder that did not previously submit the appropriate Election Materials to the Exchange Agent: (i) appropriate 15

transmittal materials and instructions for the surrender of Certificates (which shall specify that delivery shall be effected, and risk of loss and title shall pass, only upon proper delivery of the Certificates to the Exchange Agent), (ii) a FIRPTA Affidavit, and (iii) an IRS Form W-9 (in the case of a U.S. person) or appropriate IRS Form W-8 (in the case of a non-U.S. person), or applicable substitute thereof, or instructions regarding where to obtain such forms (unless the Exchange Agent already possesses such materials with respect to such holder); provided that, in the sole discretion of Parent, in the case of a Cash Consideration Holder that is an Eligible Holder that did not previously submit Eligible Holder Election Materials to the Exchange Agent, Parent may cause such holders to receive the Eligible Holder Election Materials and may permit such holders to elect to receive either Stock Consideration or Mixed Consideration if such Eligible Holder Election Materials are completed, executed and submitted to the Exchange Agent with an Election to receive Stock Consideration or Mixed Consideration within 30 days after the Effective Time. The Certificate or Certificates so delivered shall be duly endorsed as the Exchange Agent may reasonably require. The Exchange Agent shall not accept guarantee of delivery of Certificates in lieu of physical delivery of Certificates. If any Certificate shall have been lost, stolen, mislaid or destroyed, upon receipt of (i) an affidavit of that fact from the holder claiming such Certificate to be lost, mislaid, stolen or destroyed, (ii) such bond, security or indemnity as Parent and the Exchange Agent may reasonably require, (iii) such processing fee as the Exchange Agent may reasonably require and (iv) any other documents necessary to evidence and effect the bona fide exchange thereof, the Exchange Agent shall issue to such holder the consideration into which the shares represented by such lost, stolen, mislaid or destroyed Certificate shall have been converted. The Exchange Agent may establish such other reasonable and customary rules and procedures in connection with its duties as it may deem appropriate. For purposes of this Agreement, "business day" means any day that is not a Saturday or Sunday or other day on which banks are required or authorized by law to be closed in New York, New York or Dallas, Texas. (b) Each holder of Company Closing Shares that have been converted into the right to receive the Merger Consideration shall be entitled promptly to receive, upon (i) surrender to the Exchange Agent of a Certificate, together with a properly completed letter of transmittal, or (ii) receipt by the Exchange Agent of a shipment control list from the Depository Trust Company (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares, the Merger Consideration in respect of the Company Closing Shares represented by a Certificate or Uncertificated Share, together with all undelivered dividends or distributions in respect of such shares (without interest) pursuant to Section 2.7(d). The shares of Parent Common Stock issued as Merger Consideration shall be in uncertificated book-entry form unless such Parent Common Stock is issued in exchange for Certificates, in which case the holder will receive Parent Common Stock in certificated form unless such holder elects to receive book-entry shares. (c) Each of Parent, the Surviving Corporation and the Exchange Agent shall be entitled to and will deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Closing Shares such amounts, if any, as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law, including any required withholding of excise taxes under Section 4999 of the Code. To the extent that any amounts are so withheld by Parent, the Surviving Corporation or the Exchange Agent, as the case may be, such withheld amounts shall 16

be treated for all purposes of this Agreement as having been paid to the holder of the Company Closing Shares in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Exchange Agent, as the case may be, and, with respect to any such withholdings that are compensation, shall not be treated as a dividend. (d) At the Effective Time, the stock transfer books of the Company shall be closed as to holders of Company Common Stock immediately prior to the Effective Time and no transfer of Company Common Stock by any such holder shall thereafter be made or recognized. Until surrendered or transferred for exchange in accordance with the provisions of Section 2.7(a), each Certificate or Uncertificated Share theretofore representing Company Closing Shares shall from and after the Effective Time represent for all purposes only the right to receive the applicable Merger Consideration in exchange therefor, subject, however, to the Surviving Corporation's obligation to pay any dividends or make any other distributions with a record date prior to the Effective Time which have been declared or made by the Company in respect of such shares of Company Common Stock in accordance with the terms of this Agreement and which remain unpaid at the Effective Time. Whenever a dividend or other distribution is declared by Parent on the Parent Common Stock, the record date for which is at or after the Effective Time, the declaration shall include dividends or other distributions on all shares of Parent Common Stock issuable pursuant to this Agreement, but after the Effective Time no dividend or other distribution payable to the holders of record of Parent Common Stock as of any time subsequent to the Effective Time shall be delivered to the holder of any Certificate or Uncertificated Share until such holder surrenders such Certificate or transfers such Uncertificated Share for exchange as provided in Section 2.7(a). If any portion of the Cash Consideration is to be paid to a person other than the person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered, it shall be a condition to such payment that (i) either such Certificate shall be properly endorsed or shall otherwise be in proper form for transfer or such Uncertificated Share shall be properly transferred and (ii) the person requesting such payment shall pay to the Exchange Agent any transfer or other taxes required as a result of such payment to a person other than the registered holder of such Certificate or Uncertificated Share or establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable. No Mixed Consideration or Stock Consideration shall be paid to a person other than the person in whose name the surrendered Certificate or the transferred Uncertificated Share is registered as of the Effective Time. If, after the Effective Time, Certificates are presented or Uncertificated Shares are transferred to the Surviving Corporation for any reason other than to perfect statutory appraisal rights, they shall be canceled and exchanged as provided in this Section 2.7. Shares of Parent Common Stock held in the Exchange Fund, until their issuance in the Merger upon surrender of Certificates or transfer of Uncertificated Shares or until such shares are delivered to a public official or Parent as contemplated by Section 2.7(f), shall be deemed issued and outstanding shares of Parent Common Stock. In connection with any meeting of stockholders of Parent, the Exchange Agent shall be directed to cause such shares to be present and counted for purposes of determining the presence of a quorum, and the Exchange Agent shall be directed to cause such shares to be voted for, voted against, abstained and not voted in the same proportion as the shares of Parent Common Stock outstanding and not held in the Exchange Fund. From and after such time as any shares of Parent Common Stock held in the Exchange Fund are returned to the Company as contemplated by the last sentence of Section 2.7(f), such shares shall be deemed to be held in treasury and shall not be considered issued and outstanding shares of Parent Common Stock. 17

(e) Any portion of the Exchange Fund and any cash in lieu of fractional shares of Parent Common Stock made available to the Exchange Agent that remain undistributed to the former stockholders of the Company on the first anniversary of the Effective Time shall be delivered to Parent, upon demand, and any stockholders of the Company who have not theretofore received the Merger Consideration and cash and other dividends or distributions to which they are entitled under this Article II shall thereafter look only to Parent, as a general creditor thereof, for payment of their claim for the Merger Consideration and any dividends or distributions with respect to Parent Common Stock. (f) Neither Parent nor the Surviving Corporation shall be liable to any holder of shares of Company Common Stock for such shares (or dividends or distributions with respect thereto) or cash in lieu of fractional shares of Parent Common Stock delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. Any amounts remaining unclaimed by holders of any such shares at such date as is immediately prior to the time at which such amounts would otherwise escheat to or become property of any governmental entity shall, to the extent permitted by applicable law, become the property of Parent, free and clear of any claims or interest of any such holders or their successors, assigns or personal representatives previously entitled thereto. 2.8 Expiration of Company Rights. Immediately prior to the Effective Time, the rights to purchase Company Common Stock in accordance with the Company Rights Agreement (each, a "Company Right") shall expire as provided in the Rights Agreement Amendment.

The Company has delivered or made available to Parent complete and correct copies of its Certificate of Incorporation and Bylaws, each as amended to date, and correct and complete copies of its Subsidiaries' organizational documents, each as amended to date.

As used in this Agreement, "Parent Employee Benefit Plan" means any plan, program, policy, practice, agreement or other arrangement providing compensation or benefits in any form to any current or former employee, independent contractor, officer or director of Parent or any Subsidiaries of Parent or any beneficiary or dependent thereof, whether written or unwritten, formal or informal, including without limitation any "employee welfare benefit plan" within the meaning of Section 3(1) of ERISA ("Parent Employee Welfare Benefit Plan"), any "employee pension benefit plan" within the meaning of Section 3(2) of ERISA (whether or not such plan is subject to ERISA) ("Parent Employee Pension Benefit Plan") and any other pension, profit-sharing, bonus, incentive compensation, deferred compensation, vacation, sick pay, stock purchase, stock option, phantom equity, equity compensation, severance, employment, consulting, unemployment, hospitalization or other medical, life or other insurance, long or short-term disability, change of control, material fringe benefit, or any other plan, program or policy.

Any favorable determination letters referenced in this Section 3.2(k)(iii) cover "GUST" as defined in footnote 2 of IRS Notice 2003-49. Each Qualified Parent Employee Benefit Plan has timely made "good faith" amendments to comply with the Economic Growth and Tax Reconciliation Relief Act of 2001 as required by IRS Notice 2001-42.

(x) The consummation of the transactions contemplated by this Agreement will not, either alone or in connection with termination of employment, (A) entitle any current or former employee, independent contractor, director or officer of Parent or its Subsidiaries to severance pay, any change in control payment or any other material payment, except as expressly provided in this Agreement, (B) accelerate the time of payment or vesting, change the form or method of payment or increase the amount of compensation due, any such employee, independent contractor, director or officer, or (C) entitle any such employee, independent contractor, director or officer to any gross-up or similar material payment in respect of the excise tax described in Section 4999 of the Code.

any governmental entity, and no Parent Employee Benefit Plan is the subject of any pending application for administrative relief under any voluntary compliance program or closing agreement program of the IRS or the Department of Labor. (xii) Parent has the right to amend or terminate each Parent Employee Benefit Plan at any time without incurring any liability other than with respect to benefits that have already accrued under a Parent Employee Pension Benefit Plan. (xiii) Neither Parent nor any Parent ERISA Affiliate has a formal plan, commitment or proposal, whether legally binding or not, nor has any of them made a commitment to employees, officers, directors, consultants or independent contractors to create any additional Parent Employee Benefit Plan or modify, change or terminate any existing Parent Employee Benefit Plan, and no such plan, commitment or proposal is under serious consideration. To the knowledge of Parent, no events have occurred or are expected to occur with respect to any Parent Employee Benefit Plan that would cause a material change in the cost of providing the benefits under such plan or would cause a material change in the cost of providing for other liabilities of such plan. (xiv) None of the assets of any Parent Employee Pension Benefit Plan include "qualifying employer securities" or "qualifying employer real property" within the meaning of Section 407(d) of ERISA. (xv) Each Parent Employee Benefit Plan that is a "group health plan," as defined in Section 607(1) of ERISA, Section 5001(b)(1) of the Code or 45 C.F.R. 160.103, has been operated at all times in material compliance with the provisions of COBRA, HIPAA and any applicable, similar state law. (xvi) Each Parent Employee Pension Benefit Plan that is not qualified under Section 401(a) of the Code is exempt from part 2, 3 and 4 of Title I of ERISA as an unfunded plan that is maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees pursuant to Sections 201(2), 301(a)(3) and 401(a)(1) of ERISA.

(ii) As of the date hereof, there is no unfair labor practice charge or grievance arising out of a collective bargaining agreement or other grievance procedure against Parent or any of its Subsidiaries pending, or, to the knowledge or Parent, threatened, that constitutes, or could reasonably be expected to result in, a Parent Material Adverse Effect. 53

(iii) As of the date hereof, there is no complaint, lawsuit or proceeding in any forum by or on behalf of any present or former employee, any applicant for employment or any classes of the foregoing alleging breach of any express or implied contract of employment, any law or regulation governing employment or the termination thereof or other discriminatory, wrongful or tortious conduct in connection with the employment relationship against Parent pending, or, to the knowledge of Parent or any of its Subsidiaries, threatened, that constitutes, or could reasonably be expected to result in, a Parent Material Adverse Effect.

(i) Parent and its Subsidiaries possess or have adequate rights to use all material trademarks, trade names, patents, service marks, brand marks, brand names, computer programs, databases, industrial designs, domain names and copyrights necessary for the operation of the businesses of each of Parent and its Subsidiaries (collectively, the "Parent Intangible Property"), except where the failure to possess or have adequate rights to use such properties could not reasonably be expected to result in a Parent Material Adverse Effect. All of the Parent Intangible Property is owned or licensed by Parent or its Subsidiaries free and clear of any and all liens, claims or encumbrances, except those that could not reasonably be expected to result in a Parent Material Adverse Effect and neither Parent nor any such Subsidiary has forfeited or otherwise relinquished any Parent Intangible Property which forfeiture could reasonably be expected to result in a Parent Material Adverse Effect.

Other than as contemplated by Section 3.2(c), no consents, assignments, waivers, authorization or other certificates or material payments are necessary in connection with the transactions contemplated hereby to provide for the continuation in full force and effect of all of the Parent Contracts after the Closing, except to the extent the failure to obtain any such consent, assignment, waiver, authorization or other certificate, individually or in the aggregate, has not resulted in and could not reasonably be expected to result in a Parent Material Adverse Effect.

(g) For purposes of this Agreement, the following terms shall have the following meanings: (i) "Acquisition Proposal" shall mean any inquiry, offer or proposal (other than by Parent, Merger Sub or any of their respective Affiliates) relating to any transaction or series of related transactions involving: (A) any purchase from the Company or acquisition by any person, entity or "Group" (as defined under Section 13(d) of the Exchange Act and the rules and regulations thereunder) of more than a fifteen percent (15%) interest in the total outstanding voting securities of the Company or any tender offer or exchange offer that if consummated would result in any person, entity or Group beneficially owning fifteen percent (15%) or more of the total outstanding voting securities of the Company or any merger, consolidation, business combination or similar transaction involving the Company, (B) other than in the Ordinary Course of Business, any sale, lease, exchange, transfer, license, acquisition or disposition of more than fifteen percent (15%) of the assets of the Company and its Subsidiaries, taken as a whole, or (C) any liquidation or dissolution of the Company or any of its Subsidiaries; and (ii) "Superior Offer" shall mean an unsolicited, bona fide written proposal made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination, all or substantially all of the assets of the Company or all or substantially all of the outstanding voting securities of the Company (A) on terms that the Board of Directors of the Company has in good faith concluded (following consultation with and the receipt of advice from its outside legal counsel and its financial adviser), taking into account, among other things, all legal, financial, regulatory and other aspects of the offer, the person, entity or Group making the offer, the source of financing and any amounts payable pursuant to Section 7.2, to be 67

ARTICLE V ADDITIONAL AGREEMENTS 5.1 Preparation of Proxy Statement. (a) Parent and the Company shall, as promptly as practicable after the date of this Agreement, but in any event by no later than May 19, 2006, prepare and distribute to holders of Company Common Stock a proxy statement/offering memorandum relating to the Stockholders' Meeting (the "Proxy Statement"). The Proxy Statement shall (i) include copies of Parent's Annual Report on Form 10-K for the year ended December 31, 2005, Parent's Quarterly Report on Form 10-Q for the quarter ended March 31, 2006, and Parent's Proxy Statement on Schedule 14A filed with the SEC on April 19, 2006, or (ii) refer recipients of the Proxy Statement to such documents and incorporate such documents by reference into the Proxy Statement. The Proxy Statement shall also include pro forma financial information for Parent and the Company as of and for the year ended December 31, 2005. (b) The information supplied by each of Parent and the Company in the Proxy Statement shall not, at the date such materials (or any supplement thereto) are first mailed to such stockholders, at the time of the Stockholders' Meeting or at the Effective Time, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading. If at any time prior to the Effective Time any event or circumstance relating to Parent or the Company or any of their respective Subsidiaries or affiliates is discovered by Parent or the Company that should be set forth in a supplement to the Proxy Statement, Parent and the Company, as the case may be shall supplement such material. (c) The materials to be included in the Proxy Statement in the mailing to holders of Company Common Stock shall include (i) with respect to Eligible Holders, the Eligible Holder Election Materials and (ii) with respect to holders of Company Common Stock that are not Eligible Holders, the Non-Eligible Holder Election Materials. In the event Parent determines any supplemental information or materials are appropriate to be provided to the holders of Company Common Stock (x) prior to the receipt of the Stockholder Approval or (y) after receipt of the Stockholder Approval if there is a Stock Consideration Shortfall, to determine whether such holder qualifies as an accredited investor and otherwise satisfies the investor suitability standards required as set forth in the Investor Questionnaire and Election Form, then the Company shall cooperate with Parent in providing such materials to or communicating with such holders and obtaining appropriate representations and certifications or any clarification or 68

further communication with such holders as appropriate in accordance with applicable securities laws, as reasonably determined by Parent as necessary to enable the Parent to effect an issuance of Parent Common Stock pursuant to this Agreement (including pursuant to Section 2.1(b)(y)). 5.2 Access to Information. Upon reasonable notice, Parent and the Company, as the case may be shall (and shall cause each of their respective Subsidiaries to) afford to the officers, employees, accountants, counsel and other representatives of the other, access, during normal business hours during the period prior to the Effective Time, to all its properties, books, contracts, commitments and records, as well as to its officers and employees and, during such period, each of Parent and the Company, as the case may be, shall (and shall cause each of its respective Subsidiaries to) furnish promptly to the other (i) a copy of each report, schedule, registration statement and other document filed with the SEC or received by it from the SEC and (ii) all other information concerning its business, properties and personnel as such other party may reasonably request. Each of Parent and the Company agree that it will not, and will cause its respective representatives not to, use any information obtained pursuant to this Section 5.2 for any purpose unrelated to the consummation of the transactions contemplated by this Agreement. The Confidentiality Agreement dated as of February 15, 2006 between Parent and the Company (the "Confidentiality Agreement") shall apply with respect to information furnished thereunder or hereunder and any other activities contemplated thereby. 5.3 Stockholders' Meeting. (a) The Company shall take all action necessary in accordance with the DGCL and its organizational documents to call, hold and convene a special meeting of the Company's stockholders to consider the approval of this Agreement and the Merger (the "Stockholders' Meeting"), to be held as promptly as practicable after the mailing of the Proxy Statement to its stockholders, but in no event later than June 19, 2006 (unless the Stockholders' Meeting is adjourned or postponed in accordance with the provisions of this Section 5.3(a)); provided that, the Company shall not be in violation of the immediately preceding sentence if the Stockholders' Meeting is not held on or before June 19, 2006, because Parent failed to provide to the Company information regarding Parent for inclusion in the Proxy Statement (which information both Parent and the Company mutually agreed to include in the Proxy Statement) in order for the Proxy Statement to be distributed to holders of Company Common Stock on or before May 19, 2006. Subject to Section 4.2(d) and 5.3(b), the Company shall use all reasonable efforts to solicit from its stockholders proxies in favor of the approval of this Agreement and the Merger, and shall take all other action necessary or advisable to secure the vote or consent of its stockholders required by the DGCL to obtain such approvals. Notwithstanding anything to the contrary contained in this Agreement, but subject to Section 7.1(c), (i) the Company may adjourn or postpone the Stockholders' Meeting if as of the time for which the Stockholders' Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of capital stock of the Company represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Stockholders' Meeting, and (ii) Parent may require the Company to adjourn or postpone the Stockholders' Meeting if as of the time for which the Stockholders' Meeting is originally scheduled (as set forth in the Proxy Statement) the condition set forth in Section 6.2(h) shall not be satisfied; provided that, in the event the Stockholders' Meeting is delayed to a date after the Initial Termination Date as a result of the reasons set forth in this sentence, then the Initial Termination Date shall be extended to a date no later than the 69

fifth business day after the Initial Termination Date. Except as set forth in the immediately preceding sentence, the Company shall not postpone or adjourn the Stockholders' Meeting without the consent of Parent. The Company shall ensure that the Stockholders' Meeting is called, noticed, convened, held and conducted, and that all proxies solicited, by it in connection with the Stockholders' Meeting are solicited in compliance with the DGCL, its organizational documents and all other applicable laws. (b) Except to the extent expressly permitted by Section 4.2(d): (i) the Board of Directors of the Company shall unanimously recommend that the stockholders of the Company vote in favor of the approval of this Agreement and the Merger at the Stockholders' Meeting, (ii) the Proxy Statement shall include a statement to the effect that the Board of Directors of the Company has unanimously recommended that the Company's stockholders vote in favor of the approval of this Agreement and the Merger at the Stockholders' Meeting, and (iii) neither the Board of Directors of the Company nor any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify in a manner adverse to Parent, the unanimous recommendation of the Company's Board of Directors that the stockholders of the Company vote in favor of the approval of this Agreement and the Merger. 5.4 Third Party Consents; Approvals. (a) The Company shall use commercially reasonable efforts to assist Parent in promptly obtaining the written consent, waiver or approval from any party to a Company Contract identified on Schedule 3.1(z) of the Company Disclosure Schedule as requiring the consent, waiver of approval of another party thereto. Notwithstanding the foregoing, the Company and its Subsidiaries shall not, in obtaining any such consent, without the prior written consent of Parent, (i) take any action prohibited by Section 4.2, or (ii) otherwise modify or amend any Company Contract or agree to or incur any liability or obligation for which the Surviving Corporation would have any responsibility after the Effective Time. (b) Each party hereto shall cooperate and use its commercially reasonable efforts to promptly prepare and file all necessary documentation to effect all necessary applications, notices, petitions, filings and other documents, and use all commercially reasonable efforts to obtain (and will cooperate with each other in obtaining) any consent, acquiescence, authorization, order or approval of, or any exemption or nonopposition by, any Governmental Entity required to be obtained or made by Parent or the Company or any of their respective Subsidiaries in connection with the Merger or the taking of any action contemplated thereby or by this Agreement. 5.5 Employee and Benefit Plan Matters. (a) Parent and the Company agree that all employees of the Company and its Subsidiaries immediately prior to the Effective Time shall continue to be employed by the Surviving Corporation or its Subsidiaries immediately after the Effective Time solely on an "at will" basis, it being understood that the Surviving Corporation shall not have any obligations to continue employing such employees for any length of time thereafter. 70

(b) Parent shall take such action as may be necessary so that on and after the Effective Time employees of the Company and its Subsidiaries immediately prior to the Effective Time who continue in the employment of the Surviving Corporation and its Subsidiaries after the Effective Time shall be provided employee benefits, plans and programs which, in the aggregate, are substantially comparable to those made available by Parent and its Subsidiaries to similar situated employees of Parent and its Subsidiaries. (c) Parent shall, no later than sixty days following the end of the calendar year that includes the Effective Time, pay to each employee of the Surviving Corporation or a Subsidiary thereof on and after the Effective Time who was an employee of the Company or a Subsidiary thereof immediately prior to the Effective Time and who, as of the Effective Time, had paid or incurred deductible(s) for benefits under the Company's or its Subsidiary's medical plan in the plan year that includes the Closing Date in an amount in excess of $500, an amount equal to the difference of (i) the amount equal to the sum of (A) the deductible(s) paid or incurred by such employee for benefits under the Company's or its Subsidiary's medical plan in the plan year that includes the Closing Date, and (B) the deductible(s) paid or incurred by such employee for benefits under the Range Resources Corporation Welfare Benefit Plan in the plan year that includes the Closing Date, minus (ii) $1,000.00 (to the extent such amount is a positive number). (d) Parent shall take all reasonable steps necessary to cause the Company's 401(k) plan to be merged with and into Parent's 401(k) plan in which employees of the Surviving Corporation will participate after the Effective Time on or before January 1, 2007 (it being expressly agreed that the participants in the Company's 401(k) plan shall be third party beneficiaries of this Section 5.5(d), each of whom may enforce the provisions of this Section 5.5(d)). (e) Parent has previously delivered to the Company copies of each of the letters offering employment to the employees of the Company listed on Schedule 5.5 of the Parent Disclosure Schedule, and Parent will offer to employ such employees as of the Effective Time on the terms set forth in such letters. (f) In the event that, within the period beginning on the Effective Time and ending on the last day of the twelfth full calendar month following the calendar month in which the Effective Time occurs, any person who is an employee of the Company or any of its Subsidiaries immediately prior to the Effective Time, other than those employees listed on Schedule 5.5(f) of the Company Disclosure Schedule, incurs an "Involuntary Termination of Employment" (as defined in Parent's Employee Change of Control and Severance Pay Plan as in effect on the date of this Agreement) from the Surviving Corporation, then Parent shall pay severance benefits to such employee in an amount equal to one-half (1/2) of such employee's Base Salary (as defined in Parent's Employee Change of Control and Severance Pay Plan as in effect on the date of this Agreement). (g) Prior to the Effective Time, the Company will make cash payments to certain employees of the Company in the amounts set forth on Schedule 5.5(g) of the Company Disclosure Schedule. 71

(h) Immediately prior to the Effective Time, the Company will adopt (or cause the sponsoring Subsidiary to adopt) a resolution fully vesting all employer contributions made prior to the Closing Date under the 401(k) plan in which employees of the Company and its Subsidiaries participate. (i) Parent and Company agree that Patrick J. Noyes ("Noyes") will resign as President, Chief Executive Officer and Chairman of the Board of Directors of the Company at the request of Parent as of the Effective Time and that (i) such resignation will be deemed to constitute an involuntary termination of employment other than for "Cause" for purposes of the Employment Agreement between Noyes and the Company dated October 1, 2005, (ii) Noyes will be entitled to the severance payment specified on Schedule 5.5(g) of the Company Disclosure Schedule and the health insurance continuation benefits specified in Section 6(c) of that agreement, and (iii) all Company Options held by Noyes shall be fully vested and all restrictions on Company Restricted Stock held by Noyes shall lapse immediately prior to his resignation. 5.6 Stock Options and Restricted Stock. (a) At the Effective Time, each then outstanding Company Option, whether vested or unvested, shall be (i) assumed by Parent in accordance with the terms and conditions of the applicable Company Stock Plan and option agreement, together with amendments thereto, by which it is evidenced, except that from and after the Effective Time, Parent and its Board of Directors or Compensation Committee, as the case may be, shall be substituted for the Company and its Board of Directors and Compensation Committee administering any such Company Stock Plan, and (ii) converted into an option to acquire the number of shares of Parent Common Stock equal to the number of shares of Company Common Stock subject to such Company Option multiplied by the Exchange Ratio, which converted option shall be exercisable on the terms and conditions as were applicable under such Company Option and the applicable Company Stock Plan (except as described below) for the aggregate exercise price equal to the number of shares of Company Common Stock subject to such Company Option multiplied by the exercise price per share of Company Common Stock stated in such Company Option (such that, upon conversion of the Company Option into an option for an aggregate number of shares of Parent Common Stock, then the exercise price per whole share of Parent Common Stock for that converted option will be equal to the quotient of the exercise price per share of Company Common Stock stated in such Company Option divided by the Exchange Ratio). "Company Options" means any option granted, and not exercised, expired or terminated, to a current or former employee, director or independent contractor of the Company or any Subsidiaries of the Company or any predecessor thereof to purchase shares of Company Common Stock pursuant to the Company Stock Plans or any other contract or agreement entered into by the Company or any Subsidiaries of the Company. In the event that the exercise of any Company Option would result in the issuance of a fractional share of Parent Common Stock, then (i) if the Company Option is subject to a Company Stock Plan that addresses the treatment of such fractional share, such fractional share shall be treated in accordance with the terms of such Company Stock Plan, or (ii) if the Company Option is subject to a Company Stock Plan that does not address the treatment of such fractional share, such holder shall be entitled to receive a cash payment for such fractional share based upon the last reported sale price per share of Parent Common Stock on the trading day immediately preceding the date of exercise. Notwithstanding the foregoing, in the case of 72

any option to which Section 421 of the Code applies by reason of its qualification under any of Sections 422-424 of the Code, the option price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in order to comply with Section 424(a) of the Code. Except as otherwise set forth in this Section 5.6, the term, status as an "incentive stock option" under Section 422 of the Code, if applicable, all applicable restrictions or limitations on transfer and all other terms and conditions of the Company Options will, to the extent permitted by law and applicable agreements and plans and otherwise reasonably practicable, be unchanged. Notwithstanding the foregoing, all Company Options shall be fully exercisable immediately prior to the Effective Time. As soon as practicable following the date of this Agreement, the Board of Directors of the Company (or, if appropriate, any committee thereof administering the Company Stock Plans) shall adopt such resolutions or take such other actions as may be required to effect the provisions of this Section 5.6(a). (b) As soon as reasonably practicable following the Effective Time and in any event within two business days after the Effective Time, Parent shall cause the shares of Parent Common Stock issuable upon exercise of the Company Options to be assumed under paragraph (a) above that are held by holders the issuance to which is eligible to be covered on a Form S-8 to be registered on Form S-8 (or any successor form), and shall use its commercially reasonable efforts to maintain the effectiveness of such registration statement for so long as such assumed Company Options remain outstanding (it being expressly agreed that the holders of the assumed Company Options shall be third party beneficiaries of this Section 5.6(b), each of whom may enforce the provisions of this Section 5.6(b)). (c) As soon as reasonably practicable following the Effective Time, Parent shall deliver to each holder of an assumed Company Option an appropriate notice setting forth such holder's rights pursuant to such Company Option. The Company and Parent shall take all commercially reasonable actions which are necessary in order to effect the foregoing provisions of this Section 5.6 as of the Effective Time. Parent shall take all corporate actions necessary to reserve for issuance a sufficient number of shares of Parent Common Stock for delivery upon exercise of the Company Options. (d) Concurrently with the execution and delivery of this Agreement, the Company is delivering to Parent the Option Cancellation Agreements and Option Modification Agreements listed on Schedule 5.6(d) of the Company Disclosure Schedule executed by the applicable optionees and shall take all actions necessary to enforce such agreements prior to the Effective Time. Within three days of the execution and delivery of this Agreement, the Company will deliver to Parent the Option Conditional Exercise Agreements listed on Schedule 5.6(d) of the Company Disclosure Schedule executed by the applicable optionees and shall take all actions necessary to enforce such agreements prior to the Effective Time. (e) All restrictions on shares of Company Restricted Stock shall lapse and the restricted period shall end immediately prior to the Effective Time. As soon as practicable following the date of this Agreement, the Board of Directors of the Company (or, if appropriate, any committee thereof administering the Company Stock Plans) shall adopt such resolutions or take such other actions as may be required to effect the provisions of this Section 5.6(e). 73

5.7 Indemnification; Directors' and Officers' Insurance. (a) Parent agrees that all rights to indemnification by the Company now existing in favor of each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time an officer or director of the Company or any Subsidiary of the Company or an employee of the Company or any Subsidiary of the Company or who acts as a fiduciary under any of the Company Employee Benefit Plans (each a "Company Indemnified Party") as provided in the Company's Certificate of Incorporation or Bylaws, in each case as in effect on the date of this Agreement, or pursuant to any other agreements in effect on the date hereof, copies of which have been provided to Parent, including provisions relating to the advancement of expenses incurred in the defense of any action or suit, shall survive the Merger and shall remain in full force and effect with respect to all losses, claims, damages, liabilities, fees, expenses, judgments and fines arising in whole or in part out of actions or omissions in such person's capacity as such occurring at or prior to the Effective Time. From and after the Effective Time, the Surviving Corporation shall be liable to pay and perform in a timely manner such indemnification obligations. (b) The obligations of Parent and the Surviving Corporation under this Section 5.7 shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Company Indemnified Party to whom this Section 5.7 applies for a period of six years from the Effective Time without the consent of such affected Company Indemnified Party (it being expressly agreed that the Company Indemnified Parties to whom this Section 5.7 applies shall be third party beneficiaries of this Section 5.7, each of whom may enforce the provisions of this Section 5.7). (c) Within two days after the date of this Agreement, the Company shall execute and deliver to Parent letters changing the broker of record on the Company's directors' and officers' liability insurance policies to an insurance broker designated by Parent. Upon delivery of such letters, Parent shall use commercially reasonable efforts to arrange to procure, and shall prior to the Effective Time procure (and the Company shall cooperate prior to the Effective Time in these efforts), through such insurance broker designated by Parent a run-off directors' and officers' liability insurance policy for the Company's current policies to be effective from and after the Effective Time with respect to claims arising from facts or events which occurred prior to the Effective Time and covering persons who are currently covered by such insurance, which policy, without any lapse in coverage, will provide coverage for a period of six years after the Effective Time (or the Surviving Corporation otherwise will maintain coverage for such period) and contain terms and conditions which are substantially comparable to the Company's existing directors' and officers' liability insurance policy. (d) In the event that the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, in each such case, Parent shall ensure that proper provisions shall be made so that the successors and assigns of the Surviving Corporation or all or substantially all of its assets shall assume the obligations set forth in this Section 5.7 (it being agreed that this Section 5.7(d) shall be deemed satisfied if such obligations become the obligations of any such successor or assign by operation of law). 74

5.8 Agreement to Defend. In the event any claim, action, suit, investigation or other proceeding by any governmental body or other person or other legal or administrative proceeding is commenced that questions the validity or legality of the transactions contemplated hereby or seeks damages in connection therewith, the parties hereto agree to cooperate and use their commercially reasonable efforts to defend against and respond thereto. 5.9 Public Announcements. The parties hereto will consult with each other before issuing any press release or otherwise making any public statements with respect to the transactions contemplated by this Agreement, and shall not issue any such press release or make any such public statement without the consent of the other parties, except as may be reasonably determined to be required by applicable law or by obligations pursuant to any listing agreement with any national securities exchange or transaction reporting system so long as the other parties are notified promptly by the disclosing party of such press release or public statement. Notwithstanding the foregoing, the parties hereto acknowledge and agree that, (a) promptly following the execution and delivery of this Agreement by all of the parties hereto, each of Parent and the Company shall issue separate press releases announcing the execution and delivery of this Agreement (provided that, prior to the public dissemination of each such press release, each shall provide to the other a draft of such press release and an opportunity to provide comments thereon, which comments such party shall not unreasonably refuse to incorporate into such disclosure), (b) within four business days after the date of this Agreement, Parent shall file with the SEC a Current Report on Form 8-K to disclose this Agreement and attach a copy of the press release to such Form 8-K, and (c) on the date the Proxy Statement is mailed to holders of Company Common Stock, Parent shall file an amendment to such Form 8-K attaching a copy of this Agreement (but not the Company Disclosure Schedule or Parent Disclosure Schedule) as an exhibit to such Form 8-K amendment. 5.10 Other Actions. Except as contemplated by this Agreement, neither Parent nor the Company shall, nor shall Parent or the Company permit any of its Subsidiaries to, take or agree or commit to take any action that is reasonably likely to result in any of its respective representations or warranties hereunder being untrue in any material respect or in any of the conditions to the Merger set forth in Article VI not being satisfied. Subject to the terms of this Agreement, each of the parties agrees to use its reasonable best efforts to satisfy the conditions to Closing set forth in this Agreement. 5.11 Notification of Certain Matters; Governmental Filings. Parent and the Company, as the case may be, shall confer on a regular basis with each other, report on operational matters and promptly advise each other orally and in writing of any change or event constituting or which could reasonably be expected to result in a Parent Material Adverse Effect or a Company Material Adverse Effect, as the case may be. The Company agrees to give prompt notice to Parent of, and to use its commercially reasonable efforts to prevent or promptly remedy, (a) the occurrence or failure to occur, or the impending or threatened occurrence or failure to occur, of any event which occurrence or failure to occur would be reasonably likely to cause the failure of any of the conditions set forth in Section 6.2(a) or 6.2(b); provided, however, that the delivery of any notice pursuant to this Section 5.11 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice. Parent agrees to give prompt notice to the Company of, and to use its commercially reasonable efforts to prevent or promptly remedy, (i) the occurrence or failure to occur, or the impending or threatened occurrence or failure to occur, 75

of any event which occurrence or failure to occur would be reasonably likely to cause the failure of any of the conditions set forth in Section 6.3(a) or 6.3(b); provided, however, that the delivery of any notice pursuant to this Section 5.11 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice. Parent and the Company shall promptly provide each other (or their respective counsel) copies of all filings made by such party or its Subsidiaries with the SEC or any other state or federal Governmental Entity in connection with this Agreement and the transactions contemplated hereby. 5.12 Conveyance Taxes. Parent and the Company will (a) cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp Taxes, any transfer, recording, registration and other fees and any similar Taxes which become payable in connection with the transactions contemplated by this Agreement that are required or permitted to be filed on or before the Effective Time, (b) cooperate in the preparation, execution and filing of all returns, questionnaires, applications or other documents regarding any applicable exemptions to any such Tax or fee, and (c) each pay any such Tax or fee which becomes payable by it on or before the Effective Time. 5.13 Plan of Reorganization and Certain Tax Matters. (a) Parent and the Company represent and agree: (i) Parent and the Company shall each use their reasonable best efforts to cause the Integrated Transaction to qualify as a "reorganization" within the meaning of Section 368(a) of the Code, and before or after the Effective Time, neither Parent nor the Company shall knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken which action or failure to act could cause the Integrated Transaction to fail to qualify as a reorganization under Section 368(a) of the Code. (ii) Parent and the Company shall comply with the record keeping and information reporting requirements set forth in Treasury Regulation Section 1.368-3. (iii) This Agreement is intended to constitute a "plan of reorganization" within the meaning of Treasury Regulation Section 1.368-2(g) and an integrated plan within the meaning of Rev. Rul. 2001-46. (iv) In connection with the delivery by Thompson & Knight LLP, Tax counsel to the Company (or, if Thompson & Knight LLP is not able to deliver such opinion, such other legal counsel that is reasonably acceptable to the Company), of the opinion of counsel pursuant to Section 6.1(c), officers of Parent, Merger Sub and the Company shall execute and deliver to Thompson & Knight LLP or such other legal counsel certificates substantially in the form agreed to by the parties and such law firm at such time or times as may reasonably be requested by such law firm, including prior to the Effective Time (which certificates shall not, without the consent of the party delivering the certificate, which consent shall not be unreasonably withheld, cover matters in addition to those set forth in this Section 5.13 (or cover such matters more broadly than this Section 5.13) with respect to such party). 76

(v) The Company and Parent shall cooperate in the preparation, execution and filing of all Tax Returns, questionnaires, applications or other documents regarding any real property transfer or gains, sales, use, transfer, value added, stock transfer and stamp Taxes, and transfer, recording, registration and other fees and similar Taxes that become payable in connection with the Integrated Transaction that are required or permitted to be filed on or before the Effective Time. Each of Merger Sub and the Company shall pay, without deduction from any amount payable to holders of Company Common Stock and without reimbursement from the other party, any such Taxes or fees imposed on it by any governmental entity that becomes payable in connection with the Integrated Transaction (excluding, for the avoidance of doubt, any Tax imposed on the holders of Company Common Stock). (b) Parent and Merger Sub represent, with respect to themselves and their Subsidiaries, and agree that: (i) The Merger and the LLC Sub Merger will be carried out strictly in accordance with this Agreement, and there are no other written or oral agreements relating to the Merger or the LLC Sub Merger other than those expressly referred to in this Agreement. (ii) The Merger and the LLC Sub Merger are a part of an integrated plan for Parent to acquire the assets of the Company. The parties intend that, provided the continuity of interest requirement set forth in Treasury Regulation Section 1.368-1(e) is met, the Merger and the LLC Sub Merger will together be treated, for federal income tax purposes, as if parent had directly acquired the Company's assets through a "statutory merger" as that term is used in Section 368(a)(1)(A) of the Code. (iii) Following the Integrated Transaction, Parent, LLC Sub or one or more members of Parent's "qualified group" (as defined in Treasury Regulation Section 1.368-1(d)(4)(ii)) will either continue the historic businesses or use a significant portion of the Company's assets in a business within the meaning of Treasury Regulation Section 1.368-1(d). (iv) In connection with the Merger, no shares of Company Common Stock have been acquired or will be acquired by Parent or a Parent Related Person for consideration other than shares of Parent Common Stock other than (A) the Cash Consideration, (B) cash in lieu of fractional shares of Parent Common Stock paid pursuant to Section 2.6, (C) consideration paid to holders of Appraisal Shares pursuant to Section 262 and (D) amounts payable pursuant to the Registration Rights Agreement. Parent has no stock repurchase program and has no current plan or intention to adopt such a plan other than a stock repurchase program that complies with Rev. Rul. 99-58. (v) Neither Parent nor any Parent Related Person will in connection with the Merger purchase, redeem or otherwise acquire any of the Parent Common Stock that is issued in the Merger other than any fractional share for which Parent or any such related person pays cash as part of the Merger or other than in open market purchases of Parent Common Stock that are described in Rev. Rul. 99-58. 77

(vi) The payment of cash in lieu of fractional shares of Parent Common Stock in the Merger is solely for the purpose of avoiding the expense and inconvenience to Parent of issuing fractional shares and is not separately bargained for consideration. (vii) Neither Parent nor Merger Sub will, when the Merger occurs, be an "investment company," within the meaning of Section 368(a)(2)(F) of the Code, and will not at that time be under the jurisdiction of a court in a title 11 or similar case, within the meaning of Section 368(a)(3)(A) of the Code. (viii) There is no intercorporate indebtedness existing between Parent and the Company that was issued, acquired or will be settled at a discount. (ix) None of the compensation received by any shareholder-employees of the Company will be separate consideration for, or allocable to, any of their shares of Company Common Stock; none of the shares of Parent Common Stock received by any shareholder-employees will be separate consideration for, or allocable to, any employment agreement; and the compensation paid to any shareholder-employees of the Company who continue as employees of the Surviving Corporation following the Merger and LLC Sub Merger will be for services actually rendered and will not exceed amounts paid to third parties bargaining at arm's length for similar services.

(xi) No liabilities of any person other than the Company will be assumed by LLC Sub in the Merger and the LLC Sub Merger, and none of the shares of Company Common Stock to be surrendered in exchange for Parent Common Stock in the Merger will be subject to any liabilities. (xii) Parent and Merger Sub will each pay their respective expenses, if any, incurred in connection with the Merger. (xiii) Neither Parent nor any Parent Related Person owns, nor has it owned during the past year, any shares of stock of the Company.

(xiv) Parent has not, directly or indirectly, transferred any cash or property to the Company (or any entity controlled directly or indirectly by the Company) for less than full and adequate consideration and has not made any loan to the Company (or any entity controlled directly or indirectly by the Company) in anticipation of the Merger. (xv) Merger Sub is a Delaware corporation wholly and directly owned by Parent and has been newly formed solely to consummate the Merger. Prior to the Effective Time, Merger Sub will have no assets other than cash to satisfy capital requirements under state 78

law, and has not, and will not, conduct any business activities or other operations of any kind other than the issuance of its stock to Parent or as otherwise expressly required by this Agreement. (xvi) At the Effective Time, Merger Sub will not have or issue any warrants, options, convertible securities or any other type of right pursuant to which any person or entity could acquire any stock in Merger Sub.

(xx) No stock of Merger Sub will be issued to any person or entity other than Parent in connection with the Merger. (xxi) After the Effective Time, and at all times prior to and as of the effective time of the LLC Sub Merger (the "Second Effective Time"), Parent will be a corporation duly incorporated, validly existing and in good standing under the laws of Delaware. Subject to the accuracy of the representations made by the Company in Section 3.1(a) of this Agreement, after the Effective Time, and at all times prior to the Second Effective Time, the Surviving Corporation will be a corporation duly incorporated, validly existing and in good standing under the laws of Delaware.

(xxiii) After the Effective Time, and at all times prior to the Second Effective Time, the Surviving Corporation will not dispose of any assets held by the Surviving Corporation. (xxiv) After the Effective Time, and at all times prior to the Second Effective Time, the Surviving Corporation will not incur any additional liabilities, other than liabilities incurred in the ordinary course of business. 79

(xxv) After the Effective Time, and at all times prior to the Second Effective Time, there will be no indebtedness existing between the Surviving Corporation and Parent. (xxvi) After the Second Effective Time, LLC Sub will not transfer any of the assets of the Surviving Corporation except for (A) dispositions made in the ordinary course of business, (B) sales to a person or entity other than a Subsidiary of Parent or (C) transfers described in Section 368(a)(2)(C) of the Code or Treasury Regulation Section 1.368-2(k).. (xxvii) No stock or securities of Parent issued in connection with the Merger will be issued to any Company stockholder for services rendered to or for the benefit of Parent, Merger Sub or the Company (except to the extent of outstanding Company Options described in Section 5.6 and Company Restricted Stock). (xxviii) For federal tax purposes, LLC Sub is classified as disregarded as an entity separate from Parent in accordance with Treasury Regulation Section 301.7701-3 and neither Parent nor LLC Sub has any plan or intention to change the classification of LLC Sub as a disregarded entity for federal tax purposes. For purposes of this Section 5.13(b), a "Parent Related Person" with respect to Parent or Merger Sub shall mean: (i) a corporation that, immediately before or immediately after a purchase, exchange, redemption, or other acquisition of Parent Common Stock, is a member of an Affiliated Group (as defined herein) of which Parent (or any successor corporation) is a member, or (ii) a corporation in which Parent (or any successor corporation), owns, or which owns with respect to Parent (or any successor corporation), directly or indirectly, immediately before or immediately after such purchase, exchange, redemption, or other acquisition, at least 50% of the total combined voting power of all classes of stock entitled to vote or at least 50% of the total value of shares of all classes of stock, taking into account for purposes of this clause (ii) any stock owned by 5% or greater stockholders of Parent (or any successor) or such corporation, a proportionate share of the stock owned by entities in which Parent (or any successor) or such corporation owns an interest, and any stock which may be acquired pursuant to the exercise of options. (c) The Company represents, with respect to itself and its Subsidiaries, and agrees that: (i) The Merger will be carried out strictly in accordance with this Agreement and the Company is not a party to any other written or oral agreements regarding the Merger other than those expressly referred to in this Agreement. (ii) The Merger and the LLC Sub Merger are part of an integrated plan for Parent to acquire the assets of the Company. The parties intend that, provided the continuity of interest requirement set forth in Treasury Regulation Section 1.368-1(e) is met, the Merger and the LLC Sub Merger will be treated, for federal income tax purposes, as if Parent had 80

directly acquired the Company's assets through a "statutory merger" as that term in used in Section 368(a)(1)(A) of the Code. (iii) Neither the Company nor any Company Related Person has redeemed or acquired any Parent Common Stock or any Company Common Stock since September 23, 2005, or otherwise in connection with the Merger.

(vi) There is no intercorporate indebtedness existing between Parent and the Company that was issued, acquired or will be settled at a discount. (vii) The fair market value and the federal income tax basis of the assets of the Company to be transferred to LLC Sub in the Merger and the LLC Sub Merger will equal or exceed the sum of the liabilities assumed by LLC Sub, plus the amount of liabilities, if any, to which the transferred assets are subject. (viii) None of the compensation received by any shareholder-employees of the Company will be separate consideration for, or allocable to, any of their shares of Company Common Stock; none of the shares of Parent Common Stock received by any shareholder-employees will be separate consideration for, or allocable to, any employment agreement; and the compensation paid to any shareholder-employees of the Company who continue as employees of the Surviving Corporation following the Merger and the LLC Sub Merger will be for services actually rendered and will not exceed amounts paid to third parties bargaining at arm's length for similar services. (ix) The payment in lieu of fractional shares of Parent Common Stock in the Merger is solely for the purpose of avoiding the expense and inconvenience of issuing fractional shares and is not separately bargained for consideration. (x) The Company will not, when the Merger occurs, be an "investment company," within the meaning of Section 368(a)(2)(F) of the Code, and will not at that time be under the jurisdiction of a court in a title 11 or similar case, within the meaning of Section 368(a)(3)(A) of the Code. (xi) The assumption of liabilities of the Company pursuant to the Merger and the LLC Sub Merger is for a bona fide business purpose and the principal purpose of the assumption is not the avoidance of federal income tax on the transfer of assets of the Company to LLC Sub pursuant to the Merger and the LLC Sub Merger. (xii) No liabilities of any person other than the Company will be assumed by LLC Sub in the Merger and the LLC Sub Merger, and none of the shares of 81

Company Common Stock to be surrendered in exchange for Parent Common Stock in the Merger will be subject to any liabilities. (xiii) The Company and Company stockholders will each pay their respective expenses, if any, incurred in connection with the Merger. (xiv) No debt of the Company is guaranteed by any Company stockholder. (xv) The Company owns no Parent Common Stock. (xvi) No assets of the Company have been sold, transferred or otherwise disposed of which would prevent Parent and the Surviving Corporation from continuing the historic business of the Company or from using a significant portion of the Company's historic business assets in a business following the Integrated Transaction, within the meaning of Treasury Regulation Section 1.368-1(d). (xvii) The fair market value of the assets of the Company transferred to Merger Sub in the Integrated Transaction will equal or exceed the sum of the liabilities assumed or paid by Parent or Merger Sub, plus the amount of liabilities, if any, to which the transferred assets are subject. (xviii) The total adjusted basis of the assets of the Company transferred to Merger Sub in the Integrated Transaction will equal or exceed the sum of the liabilities assumed or paid by Parent or Merger Sub, plus the amount of liabilities, if any, to which the transferred assets are subject. (xix) The Company is not under the jurisdiction of a court in a title 11 or similar case within the meaning of Section 368(a)(3)(A) of the Code. (xx) No stock or securities of the Company will be issued to any Company stockholder for services rendered to or for the benefit of Parent, Merger Sub, or the Company in connection with the Merger (except to the extent of outstanding Company Options described in Section 5.6 and Company Restricted Stock). (xxi) No stock or securities of Parent or of the Company will be issued to any Company stockholder for any indebtedness owed to any Company stockholder in connection with the Merger. (xxii) No assets were transferred to the Company, nor did the Company assume any liabilities, in anticipation of the Merger.

(xxiv) At the Effective Time, except as contemplated by Section 3.1(b)(i), the Company will not have outstanding any warrants, options, convertible securities, or any other type of right pursuant to which any person or entity could acquire stock in the Company. For purposes of this Section 5.13(c), a "Company Related Person" with respect to the Company shall mean: (x) a corporation that, immediately before or immediately after a purchase, exchange, redemption, or other acquisition of the Company Common Stock, is a member of an Affiliated Group (as defined herein) of which the Company (or any successor corporation) is a member, or (y) a corporation in which the Company (or any successor corporation), owns, or which owns with respect to the Company (or any successor corporation), directly or indirectly, immediately before or immediately after the relevant purchase, exchange, redemption, or other acquisition, at least 50% of the total combined voting power of all classes of stock entitled to vote or at least 50% of the total value of shares of all classes of stock, taking into account for purposes of this clause (ii) any stock owned by 5% or greater stockholders of the Company (or any successor) or such corporation, a proportionate share of the stock owned by entities in which the Company (or any successor) or such corporation owns an interest, and any stock which may be acquired pursuant to the exercise of options. For purposes of Section 5.13(b) and (c), "Affiliated Group" shall mean one or more chains of corporations connected through stock ownership with a common parent corporation, but only if: (aa) the common parent owns directly stock that possesses at least 80% of the total voting power, and has a value at least equal to 80% of the total value, of the stock in at least one of the other corporations, and (bb) stock possessing at least 80% of the total voting power, and having a value at least equal to 80% of the total value, of the stock in each corporation (except the common parent) is owned directly by one or more of the other corporations. For purposes of the preceding sentence, "stock" does not include any stock that (a) is not entitled to vote, (b) is limited and preferred as to dividends and does not participate in corporate growth to any significant extent, (c) has redemption and liquidation rights that do not exceed the issue price of such stock (except for a reasonable redemption or liquidation premium), and (d) is not convertible into another class of stock. (d) In no event will the aggregate Liquidated Damages (as defined in the Registration Rights Agreement) that are paid in cash and other damages that are paid in cash under the Registration Rights Agreement and under this Agreement exceed an amount that would prevent the Merger from satisfying the continuity of interest requirement under Treasury Regulation Section 1.368-1(e). Such continuity of interest determination shall be made by the Tax counsel that delivered the opinion of counsel described in Section 6.1(c) of this Agreement or such other Tax counsel as may be selected by Parent in its reasonable discretion. To the extent that Liquidated Damages and such other damages cannot be paid in cash, they will be paid in shares of Parent Common Stock using the Fair Market Value (as defined in the Registration 83

Rights Agreement) on the dates they accrue. Notwithstanding the foregoing, if the Company does not receive the opinion of counsel described in Section 6.1(c) of this Agreement, then this Section 5.13(d) shall not apply and shall have no effect. 5.14 Financing. Prior to the Closing, the Company shall reasonably cooperate with Parent, Parent's financing sources, and Parent's auditors and attorneys in connection with Parent's financing efforts with respect to the Merger. Without limiting the generality of the foregoing, the Company shall provide, and the Company shall instruct its auditors to provide, to Parent such financial and other information that Parent reasonably requests for inclusion in any materials, including offering materials for the issuance of debt securities, to be used by Parent in connection with such financing. In addition, the Company shall, to the extent reasonably requested by Parent, use its best efforts to cause the Company's auditors to provide the consent of such auditors to the inclusion of any financial statements of the Company in any such materials used by Parent. 5.15 Resignations. At or prior to the Closing, the Company shall obtain the resignation, effective as of a time no later than the Effective Time, of each of its and its Subsidiaries' officers, directors and limited liability company managers, including those persons whose names are listed on Schedule 3.1(a) of the Company Disclosure Schedule, from all such positions such persons hold with the Company and each such Subsidiary, including offices, board positions and committee positions (but not including any person's employment with the Company or any such Subsidiaries). 5.16 Hedge Transactions.

The Company shall use commercially reasonable efforts to cause all Hedge Transactions outstanding between the Company and JPMorgan at the Closing to terminate no later than the close of business on the Closing Date. 5.17 Sparling Stock Voting Agreement.

Sparling to the Stock Voting Agreement as soon as practicable after the date hereof and shall, once obtained, furnish the Stock Voting Agreement executed by Donald P. Sparling and the Company to Parent. 84

If the Termination Fee shall be payable pursuant to subsection (b)(i) of this Section 7.2 in connection with a termination by Parent, the Termination Fee shall be paid in same-day funds no later than one business day after the date written notice of termination of this Agreement is delivered by Parent to the Company. If the Termination Fee shall be payable pursuant to subsection (b)(i) of this Section 7.2 in connection with a termination by the Company or pursuant to subsection (b)(ii) of this Section 7.2, the Termination Fee shall be paid in same-day funds concurrently with the delivery of the notice of termination, and as a condition precedent to the effectiveness of any termination, of this Agreement. (c) If (i) Parent or the Company terminates this Agreement pursuant to Section 7.1(b)(ii), (ii) Parent terminates this Agreement pursuant to Section 7.1(f) other than under the circumstances described in any of clauses (iv), (v) or (vi) of Section 7.1(f), or (iii) the Company terminates this Agreement pursuant to Section 7.1(c) and, at the time of such termination, Parent is entitled to terminate this Agreement pursuant to Section 7.1(b)(ii) or 7.1(f), and, prior to the termination of this Agreement, an Acquisition Proposal has not been proposed to the Company or otherwise publicly announced or communicated to the holders of Company Common Stock, then the Company shall pay to Parent an amount equal to the product of (A) 0.30 multiplied by (B) the Termination Fee, with such payment to be made, if the termination is 91

by the Company, in same-day funds concurrently with the delivery of the notice of termination, and as a condition precedent to the effectiveness of any termination, of this Agreement or, if the termination is by Parent, in same-day funds no later than one business day after the date written notice of termination of this Agreement is delivered by Parent to the Company; provided that, if the Company shall consummate an Acquisition Proposal within twelve months of the date of such termination, then the Company shall pay, in addition to the amount described above in this sentence, an amount equal to the balance of the Termination Fee in same-day funds at or prior to the date of the consummation of such Acquisition Proposal. (d) The parties hereto acknowledge that the agreements contained in paragraphs (b) and (c) of this Section 7.2 are an integral part of the transactions contemplated by this Agreement, and that without these agreements, they would not enter into this Agreement. Accordingly, if the Company fails to pay promptly any fee payable by it pursuant to this Section 7.2, then the Company shall pay to Parent Parent's costs and expenses (including attorneys' fees) in connection with collecting such fee, together with interest on the amount of the fee at the rate of LIBOR plus 150 basis points from the date such payment was due under this Agreement until the date of payment. The fees payable by the Company pursuant to this Section 7.2 shall be paid by the Company without reservation of rights or protests, and the Company upon making any such payment shall be deemed to have released and waived any and all claims that it may have to recover such amounts. (e) Nothing contained in this Section 7.2 shall constitute or shall be deemed to constitute liquidated damages for the breach by the Company of the terms of this Agreement or otherwise limit the rights of Parent. 7.3 Amendment. This Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after receipt of the Stockholder Approval, but, after any such approval, no amendment shall be made which by law requires further approval by such stockholders without first obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. 7.4 Extension; Waiver. At any time prior to the Effective Time, the parties hereto, by action taken or authorized by their respective Boards of Directors, may, to the extent legally allowed: (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto; (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto; and (iii) waive compliance with any of the agreements or conditions contained herein.

8.10 Severability. If any term or other provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal, or incapable of being enforced under any rule of applicable law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated herein are not affected in any manner materially adverse to any party.

The parties hereby acknowledge and agree that the failure of any party to this Agreement to perform its obligations hereunder in accordance with their specific terms or otherwise to comply with such obligations, including its failure to take all actions as are necessary on its part to the consummation of the Merger, will cause irreparable injury to the other parties to this Agreement for which damages, even if available, will not be an adequate remedy.

Parent represents and warrants to Stroud and the Holders that Parent is a WKSI. The Resale Shelf Registration Statement shall be filed on Form S-3 and shall utilize Form S-3 or the automatic shelf registration process under Rule 415 and Rule 462 under the Securities Act. If Parent loses its status as a WKSI or becomes otherwise ineligible to utilize the automatic shelf registration process, then Parent shall file the Resale Shelf Registration Statement on such form as Parent may then utilize and use its commercially reasonable efforts to have the Resale Shelf Registration Statement declared effective under the Securities Act as soon as practicable. Parent agrees to use its commercially reasonable efforts to maintain the effectiveness of the Resale Shelf Registration Statement, including by filing any necessary post-effective amendments and prospectus supplements, or, alternatively, by filing new registration statements relating to the Registrable Shares as required by Rule 415 under the Securities Act, continuously until the date (the "Resale Shelf Registration Expiration Date") which is the earliest of (i) one (1) year following the later of (A) the Effective Time or (B) the date of effectiveness of the Resale Shelf Registration Statement, or (ii) the date on which Holders no longer hold any Registrable Shares. (b) Inclusion of Registrable Shares. Upon a Holder becoming eligible to have Registrable Shares held by such Holder included in the Resale Shelf Registration Statement by delivery to Parent (or the Exchange Agent under the Merger Agreement) of a properly completed Investor Questionnaire, effecting a valid Election and the final determination of the number of Registrable Shares to be issued to such Holder pursuant to the Merger Agreement, Parent shall, within five Business Days thereafter, file a post-effective amendment or a Prospectus supplement, as applicable, to the Resale Shelf Registration Statement to name such Holder as a selling stockholder therein and include therein all Registrable Shares issued to or known to be issuable to such Holder pursuant to the Merger; provided, however, that Parent shall not be required to file a post-effective amendment or Prospectus supplement, as applicable, solely for the purpose of adding Holders of Registrable Shares held by Holder more often than 4

once each calendar week during the first four calendar weeks following the Effective Time and thereafter no more often than once in each calendar month. (c) Notification and Distribution of Materials. Parent shall notify the Holders of the effectiveness of any Registration Statement applicable to the Registrable Shares and shall furnish to the Holders, without charge, such number of copies of the Registration Statement (including any amendments, supplements and exhibits), the Prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Registration Statement or such other documents as the Holders may reasonably request in order to facilitate the sale of the Registrable Shares in the manner described in the Registration Statement. (d) Amendments and Supplements. Subject to Section 2.1(b), (i) Parent shall promptly prepare and file with the SEC from time to time such amendments and supplements to the Registration Statement and Prospectus used in connection therewith as may be necessary to keep the Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all the Registrable Shares until the Resale Shelf Expiration Date and (ii) upon five (5) Business Days' notice, Parent shall file any supplement or post-effective amendment to the Registration Statement with respect to the plan of distribution or a Holder's ownership interests in his, her or its Registrable Shares that is reasonably necessary to permit the sale of such Holder's Registrable Shares pursuant to the Registration Statement. (e) Notice of Certain Events. Parent shall promptly and in any event within three (3) Business Days notify the Holders of, and confirm in writing, any request by the SEC for any amendment or supplement to, or additional information in connection with, any Registration Statement required to be prepared and filed hereunder (or Prospectus relating thereto). Parent shall promptly and in any event within three (3) Business Days notify each Holder of, and confirm in writing, the filing of the Registration Statement or any Prospectus, amendment or supplement related thereto or any post-effective amendment to the Registration Statement and the effectiveness of any post-effective amendment. (f) Stop Orders. During the period referred to in Section 2(a), Parent shall use its commercially reasonable efforts to avoid the issuance of, or if issued, to obtain the withdrawal of, any order enjoining or suspending the use or effectiveness of a Registration Statement or suspending the qualification (or exemption from qualification) of any of the Registrable Shares for sale in any jurisdiction, as promptly as practicable. 3. SUSPENSION OF REGISTRATION REQUIREMENT; RESTRICTION ON SALES. (a) Subject to the provisions of this Section 3 and a good faith determination by Parent that it is in the best interests of Parent to suspend the use of any Resale Shelf Registration Statement, following the effectiveness of such Resale Shelf Registration Statement (and the filings with any international, federal or state securities commissions), Parent, by written notice to the Holders, may direct the Holders to suspend sales of the Registrable Shares pursuant to such Resale Shelf Statement for such times as Parent reasonably may determine is necessary and advisable (but in no event for more than 45 days in any 90-day period or more than 90 days in any 12-month period), if there shall be pending discussions relating to, or the consummation of, a transaction or the occurrence of an event (x) that would require additional disclosure of material information by Parent in the Resale Shelf Registration Statement (or such filings) and which has not been so disclosed, (y) as to which Parent has a bona fide business purpose for preserving confidentiality, or (z) that renders Parent unable to comply with Commission requirements, in each case under circumstances that would make it impractical or inadvisable to promptly amend or supplement the Resale Shelf Registration Statement (provided that each Holder acknowledges that a bona fide financing or business transaction that implicates any of the foregoing clause (x), clause (y) or clause (z) shall be deemed to constitute a circumstance that makes it impracticable or inadvisable to 5

so promptly amend or supplement the Resale Shelf Registration Statement) on a post-effective basis, as applicable (a "Suspension Event"). Upon the earlier to occur of (i) Parent delivering to the Holders an End of Suspension Notice, as hereinafter defined, or (ii) the end of the maximum permissible suspension period, Parent shall use its commercially reasonable efforts to promptly amend or supplement the Resale Shelf Registration Statement on a post-effective basis, if necessary, or to take such action as is necessary so as to permit the Holders to resume sales of the Registrable Shares as soon as possible. (b) Upon a Suspension Event, Parent shall give written notice (a "Suspension Notice") to the Holders to suspend sales of the Registrable Shares, and such notice shall state that such suspension shall continue only for so long as the Suspension Event or its effect is continuing and Parent is pursuing with reasonable diligence the completion of the matter giving rise to the Suspension Event or otherwise taking all reasonable steps to terminate suspension of the effectiveness of the Registration Statement as promptly as possible. No Holder shall effect any sales of the Registrable Shares pursuant to such Registration Statement (or such filings) at any time after it has received a Suspension Notice and prior to receipt of an End of Suspension Notice (as defined below). The Holders may recommence effecting sales of the Registrable Shares under the Registration Statement (or such filings) following further notice to such effect (an "End of Suspension Notice") from Parent, which End of Suspension Notice shall be given by Parent to the Holders in the manner described above promptly following the conclusion of any Suspension Event and its effect. (c) Notwithstanding any provision herein to the contrary, if Parent gives a Suspension Notice pursuant to this Section 3 with respect to the Resale Shelf Registration Statement, Parent shall extend the period during which such Resale Shelf Registration Statement shall be maintained effective under this Agreement by the number of days during the period from the date of the giving of the Suspension Notice to and including the date when Parent shall have given the End of Suspension Notice and copies of the supplemented or amended Prospectus necessary to resume sales; provided such period of time shall not be extended beyond the date that Common Shares are not Registrable Shares. 4. SUBSEQUENT SHELF REGISTRATION FOR ADDITIONAL SHARES ISSUED AFTER EFFECTIVENESS OF THE RESALE SHELF REGISTRATION STATEMENT. If any Additional Shares are issued or distributed to Holders after the later of (i) the effectiveness of the Resale Shelf Registration Statement or (ii) the Effective Time, or such Additional Shares were otherwise not included in a prior Registration Statement, then Parent shall as soon as practicable, at the option of Parent and subject to compliance with Section 2(b) with respect to the Holder of the Registrable Shares with respect to which such Additional Shares are issued, either (A) file an additional shelf registration statement (including the Prospectus, amendments and supplements to such registration statement or Prospectus, including pre- and post-effective amendments, all exhibits thereto and all material incorporated by reference or deemed to be incorporated by reference, if any, in such registration statement, a "Subsequent Shelf Registration Statement") covering such Additional Shares on behalf of the Holders thereof in the same manner, and subject to the same provisions in this Agreement as the Resale Shelf Registration Statement or (B) file a supplement to the Resale Shelf Registration Statement to include therein and cover such Additional Shares on behalf of the Holders. 5. RULE 144 REPORTING. With a view to making available the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Shares to the public without registration, Parent agrees to, so long as any Holder owns any Registrable Shares: (a) make and keep public information available, as those terms are understood and defined in Rule 144(c) under the Securities Act; 6

(b) use its commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required to be filed by Parent under the Securities Act and the Exchange Act; and (c) furnish to any Holder promptly upon request a written statement by Parent as to its compliance in all material respects with the reporting requirements of Rule 144 and of the Exchange Act, furnish or make available to any Holder a copy of the most recent annual or quarterly report of Parent, and such other reports and documents of Parent, and take such reasonable further actions consistent with this Section 5, as a Holder may reasonably request in availing itself of any rule or regulation of the SEC allowing a Holder to sell any such Registrable Shares without registration. 6. LIQUIDATED DAMAGES. (a) If: (i) the Resale Shelf Registration Statement is not filed with the SEC prior to or on the second Business Day after the Effective Time; (ii) the Resale Shelf Registration Statement is not effective prior to or on the second Business Day after the Effective Time; (iii) a supplement to the Prospectus included in the Resale Shelf Registration Statement (which prospectus supplement shall include all of the Holders not previously included in the Resale Shelf Registration Statement and with respect to which the conditions of Section 2(b) of this Agreement shall have been complied with and the number of Registrable Shares to be sold by each such Holder in the selling stockholder portion of such Prospectus) is not filed with the SEC prior to or on the fifth business day after the later of (A) Effective Time or (B) the date on which the conditions of Section 2(b) of this Agreement shall have been complied with respect to such Holder; or (iv) the Resale Shelf Registration Statement becomes effective under the Securities Act but (A) the Resale Shelf Registration Statement thereafter ceases to be effective or (B) as specified in Section 3(a), the Resale Shelf Registration Statement or the Prospectus ceases to be usable in connection with resales of Registrable Shares, in the case of (A) or (B) within the First Liquidated Damages Period or the Second Liquidated Damages Period and Parent fails to (1) other than in the case of a Suspension Event under Section 3, cause the Resale Shelf Registration Statement to again become effective or the Resale Shelf Registration Statement or Prospectus to become usable within five Business Days by a Prospectus supplement, post-effective amendment or a report filed pursuant to the Exchange Act or (2) if applicable, terminate the suspension period described in Section 3(a) by the 45th or the 90th day, as applicable, (each such event referred to in foregoing clauses (i) through (iv), a ("Registration Default")), Parent agrees to pay cash damages ("Liquidated Damages") to a Holder if such Holder, after the occurrence and during the continuation of a Registration Default, notifies Parent in writing (a "Default Sale Notice") that it desires to sell its Registrable Shares (which Default Sale Notice shall include the number of Registrable Shares held by such Holder and the number of Registrable Shares such Holder desires to sell), as follows: (A) if the Fair Market Value as of the date on which the Registration Default ceases to exist (or, if earlier, the date on which such Holder actually disposes of such Registrable Shares) is less than the Fair Market Value as of the date the Default Sale Notice is given to Parent, Parent shall pay to such Holder an amount equal to the product of: 7

(1) the sum of (i) the excess of (x) the Fair Market Value as of the date the Default Sale Notice is given to Parent over (y) the Fair Market Value as of the date on which the Registration Default ceases to exist (or, if earlier, the date of such disposition) (as set forth in the Default Sale Notice that Holder desired to sell), and (ii) an amount per share accruing at 6% per annum of the Fair Market Value as of the date the Default Sale Notice is given to Parent for the period from the date the Default Sale Notice is given to Parent to the date on which the Registration Default ceases to exist (or, if earlier, the date of disposition) (the "Interest Amount") multiplied by (2) the number of Registrable Shares as set forth in the Default Sale Notice that such Holder desired to sell (or, if such Holder disposed of all or a portion of its Registrable Shares in advance of the cessation of a Registration Default, the number of shares disposed of, up to the number as set forth in the Default Sale Notice that Holder desired to sell); or (B) if the Fair Market Value on the date which the Registration Default ceases to exist (or, if earlier, the date on which such Holder actually disposes of such Registrable Shares) is greater than the Fair Market Value as of the date the Default Sale Notice is given to Parent (such excess amount herein referred to as the "Profit Amount"), Parent shall pay to Holder an amount equal to the product of (1) the excess of (x) the Interest Amount over (y) the Profit Amount multiplied by (2) the number of Registrable Shares as set forth in the Default Sale Notice that such Holder desired to sell (or, if such Holder disposed of all or a portion of its Registrable Shares in advance of the cessation of a Registration Default, the number of shares disposed of, up to the number as set forth in the Default Sale Notice that Holder desired to sell); (b) This Section 6 shall set forth sole and exclusive remedy of Holders with respect to a Registration Default. Upon payment of Liquidated Damages with respect to any Registrable Shares held by a Holder, such Holder shall continue to be entitled to its rights under this Agreement, other than this Section 6, with respect to such Registrable Shares but shall not have any further rights under this Section 6 with respect to such Registrable Shares with respect to which such Liquidated Damages shall have been paid. For purposes of this Section 6, a Registration Default shall be deemed to cease with respect to a Registrable Share upon the date such Registrable Share ceases to constitute a Registrable Share. 7. STATE SECURITIES LAWS. Subject to the conditions set forth in this Agreement, Parent shall, in connection with the filing of any Registration Statement hereunder, file such documents as may be necessary to register or qualify the Registrable Shares under the securities or "blue sky" laws of such states as the Holders may reasonably request in connection with the offer and sale of Registrable Shares pursuant to the intended methods of disposition by the Holders as set forth in the applicable Registration Statement, and Parent shall use its commercially reasonable efforts to cause such filings to become effective in a timely manner; provided, however, that Parent shall not be obligated to qualify as a foreign corporation to do business under the laws of any such state in which it is not then qualified or to file any general consent to service of process in any such state. Once effective, Parent shall use its commercially 8

reasonable efforts to keep such filings effective until the earlier of (a) such time as all of the Registrable Shares have been disposed of in accordance with the intended methods of disposition by the Holders as set forth in the applicable Registration Statement, (b) in the case of a particular state, the applicable Holders have notified Parent that they no longer require an effective filing in such state in accordance with their original request for filing or (c) the date on which the applicable Registration Statement ceases to be effective. 8. LISTING. Parent will cause all Registrable Shares to be listed or otherwise eligible for full trading privileges on the principal national securities exchange (currently NYSE) on which the Common Shares are then listed or quoted, not later than the date on which the Registrable Shares are issued by Parent to a Holder. Parent will use its commercially reasonable efforts to continue the listing or trading privilege for all Registrable Shares on such exchange. Parent will as promptly as practicable notify the Holders of, and confirm in writing, the delisting of the Common Shares by such exchange. 9. EXPENSES. Parent shall bear all Registration Expenses incurred in connection with the registration of the Registrable Shares pursuant to this Agreement and Parent's performance of its other obligations under the terms of this Agreement. The Holders shall bear all underwriting fees, discounts or commissions attributable to the sale of securities by the Holders, or any legal fees and expenses of counsel to the Holders (except as otherwise specifically provided herein) and all other expenses incurred in connection with the performance by the Holders of their obligations under the terms of this Agreement. 10.

the delivery by Parent of an End of Suspension Notice. The indemnity provided for herein shall remain in full force and effect regardless of any investigation made by or on behalf of any Indemnitee. 11. COVENANTS OF HOLDERS. Each of the Holders hereby agrees (i) to cooperate with Parent and to furnish to Parent all such information concerning its plan of distribution and ownership interests with respect to its Registrable Shares in connection with the preparation of a Registration Statement with respect to such Holder's Registrable Shares and any filings with any state securities commissions as Parent may reasonably request (and Parent may exclude from any registration pursuant hereto the Registrable Shares of any Holder who fails to furnish such information within a reasonable time after receiving such request), (ii) to indemnify Parent, its officers, directors, employees, agents, representatives and Affiliates, and each Person, if any, who controls Parent within the meaning of the Securities Act, and each other Person, if any, subject to liability because of his, her or its connection with Parent, against any and all losses, claims, damages, actions, liabilities, costs and expenses arising out of or based upon any untrue statement or alleged untrue statement of material fact contained in either such Registration Statement or the Prospectus contained therein, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, if and to the extent that such statement or omission occurs from reliance upon and in conformity with written information regarding such Holder, his, her or its plan of distribution or his, her or its ownership interests, which was furnished to Parent in writing by such Holder pursuant to an Investor Questionnaire or otherwise expressly for use therein unless such statement or omission was corrected in writing to Parent prior to the date one day prior to the date of the final Prospectus (as supplemented or amended, as the case may be). 12. INDEMNIFICATION PROCEDURES. Any Person entitled to indemnification under this Agreement shall notify promptly the indemnifying party in writing of the commencement of any action or proceeding with respect to which a claim for indemnification may be made hereunder, but the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its obligations hereunder, except to the extent the indemnifying party is materially prejudiced thereby and shall not relieve the indemnifying party from any liability which it may have to any indemnified party otherwise than hereunder. In case any action or proceeding is brought against an indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, unless in the reasonable opinion of outside counsel to the indemnified party a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, to assume the defense thereof (alone or jointly with any other indemnifying party similarly notified), to the extent that it chooses, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party that it so chooses (provided that in connection with such assumption the indemnifying parties provide the indemnified parties a full release of any costs or other expenses in connection therewith), the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof; provided, however, that (a) if the indemnifying party fails to take reasonable steps necessary to defend diligently the action or proceeding within twenty (20) Business Days after receiving notice from such indemnified party that the indemnified party believes it has failed to do so; or (b) if such indemnified party who is a defendant in any action or proceeding which is also brought against the indemnifying party shall have reasonably concluded, based on the advice of counsel, that there may be one or more legal defenses available to such indemnified party which are not available to the indemnifying party; or (c) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the indemnified party shall have the right to assume or continue its own defense as set forth above (but with no more than one firm of counsel for all indemnified parties in each jurisdiction) and the indemnifying party shall be liable for any expenses therefor. No indemnifying party shall, without the written consent of the indemnified party (which shall not be unreasonably withheld), effect the settlement or compromise of, or consent to the 10

entry of any judgment with respect to, any pending or (to the knowledge of the indemnifying party) threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim, (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party and (iii) does not and is not likely to materially adversely effect the indemnified party. 13. LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the date of this Agreement, Parent shall not, without the prior written consent of the Holders of a majority of the then outstanding Registrable Shares, enter into any agreement with any holder or prospective holder of any securities of Parent that would allow such holder or prospective holder to include such securities in the Resale Shelf Registration Statement filed pursuant to the terms hereof, unless under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of Registrable Shares of the Holders that is included. 14. CONTRIBUTION. (a) If the indemnification provided for in Section 10 and Section 11 is unavailable to an indemnified party with respect to any losses, claims, damages, actions, liabilities, costs or expenses referred to therein or is insufficient to hold the indemnified party harmless as contemplated therein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, actions, liabilities, costs or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, actions, liabilities, costs or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, shall be determined by reference to, among other factors, whether the untrue or alleged untrue statement of a material fact or omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided, however, that in no event shall the obligation of any indemnifying party to contribute under this Section 14 exceed the amount that such indemnifying party would have been obligated to pay by way of indemnification if the indemnification provided for under Section 10 or Section 11 hereof had been available under the circumstances. (b) Parent and the Holders agree that it would not be just and equitable if contribution pursuant to this Section 14 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. (c) Notwithstanding the provisions of this Section 14, no Holder shall be required to contribute any amount in excess of the amount by which the gross proceeds from the sale of Registrable Shares exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission. No indemnified party guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any indemnifying party who was not guilty of such fraudulent misrepresentation. 15. AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be amended, modified, or supplemented or waived without the prior written consent of Parent and Holders of a majority of the aggregate of the outstanding Registrable Shares. 11

SUCCESSORS AND ASSIGNS; THIRD PARTY BENEFICIARIES. Neither Parent, the Company or any Holder shall be entitled to assign any of its rights or obligations under this Agreement without, in the case of Parent, the consent of a majority of the aggregate number of the outstanding Registrable Shares or, in the case of any Holder, upon the prior written consent of Parent (which consent Parent may withhold in its sole discretion); and no Transferee of any Registrable Shares shall be entitled to any rights under this Agreement. This Agreement shall inure to the benefit of and be binding upon the successors and permitted assigns of each of the parties hereto and shall inure to the benefit of each Holder. Parent agrees that the Holders shall be third party beneficiaries to the agreements made hereunder by Stroud and Parent, and each Holder shall have the right to enforce such agreements directly to the extent it deems such enforcement necessary or advisable to protect its rights hereunder; provided, however, that such Holder fulfills all of its obligations hereunder. 18. COUNTERPARTS. This Agreement may be executed in any number of counterparts and by the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 19. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas applicable to contracts made and to be performed wholly within said State. 12

20. SEVERABILITY. In the event that any one or more of the provisions contained herein, or the application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be in any way impaired thereby, it being intended that all of the rights and privileges of the parties hereto shall be enforceable to the fullest extent permitted by law. 21. ENTIRE AGREEMENT. This Agreement and the Merger Agreement, are intended by the parties as a final expression of their agreement and intended to be the complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein, with respect to such subject matter. This Agreement supersedes all prior agreements and understandings between the parties with respect to such subject matter. 22. REGISTRABLE SHARES HELD BY PARENT OR ITS AFFILIATES. Whenever the consent or approval of Holders of a specified percentage of Registrable Shares is required hereunder, Registrable Shares held by Parent or its Affiliates shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 23. SURVIVAL. The indemnification and contribution obligations under Section 10, Section 11 and Section 14 shall survive the termination of Parent's obligations under Section 2(a). 24. DRAFTING CONVENTIONS; NO CONSTRUCTION AGAINST DRAFTER. (a) The headings in this Agreement are provided for convenience and do not affect its meaning. The words "include", "includes" and "including" are to be read as if they were followed by the phrase "without limitation". Unless specified otherwise, any reference to an agreement means that agreement as amended or supplemented, subject to any restrictions on amendment contained in such agreement. Unless specified otherwise, any reference to a statute or regulation means that statute or regulation as amended or supplemented from time to time and any corresponding provisions of successor statutes or regulations. If any date specified in this Agreement as a date for taking action falls on a day that is not a business day, then that action may be taken on the next business day. Unless specified otherwise, the words "party" and "parties" refer only to a named party to this Agreement. (b) The parties have participated jointly with their respective counsel in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement is to be construed as if drafted jointly by the parties and there is to be no presumption or burden of proof favoring or disfavoring any party because of the authorship of any provision of this Agreement. 25. CONTINUITY OF INTEREST DETERMINATION. In no event will the aggregate Liquidated Damages and other damages that are paid in cash under this Agreement exceed an amount that would prevent the Merger from satisfying the continuity of interest requirement under Treas. Reg. Section 1.368-1(e). Such continuity of interest determination shall be made by the Tax counsel that delivered the opinion of counsel described in Section 6.1(c) of the Merger Agreement or such other Tax counsel as may be selected by Parent in its reasonable discretion. To the extent that Liquidated Damages and such other damages cannot be paid in cash, they will be promptly paid in Common Shares using the Fair Market Value on the dates that they accrue. Notwithstanding the foregoing, if Stroud does not receive the opinion of counsel described in Section 6.1(c) of the Merger Agreement, then this Section 25 shall not apply and shall have no effect. 26. OTHER REGISTRATION RIGHTS AGREEMENTS. Effective as of the Effective Time, this Agreement replaces and supersedes in its entirety all rights of each Holder under or pursuant to (a) the Second Amended and Restated Registration Rights Agreement, dated as of September 21, 2005, between Stroud and the parties listed on the signature page thereto, and (b) the Registration Rights Agreement, 13

dated as of September 22, 2005, between Stroud and Raymond James & Associates, Inc., which agreements shall terminate and be of no force or effect, and Stroud shall have no further obligations thereunder, with respect to any Holder as of the Effective Time. 27.
