The obligation of Merger Subsidiary to, and of Parent to cause Merger Subsidiary to, accept for payment and pay for any Shares tendered shall be subject only to the satisfaction of the conditions set forth in Annex A and to the terms and conditions of this Agreement; provided that Parent and Merger Subsidiary may waive any of the conditions to the Offer (other than the Minimum Condition, which may not be waived without the prior written consent of the Company) and may make changes in the terms and conditions of the Offer except that, without the prior written consent of the Company, no change may be made to the form of consideration to be paid, no decrease in the Offer Price or the number of Shares sought in the Offer may be made, no change which imposes additional conditions to the Offer or modifies any of the conditions set forth in Annex A in any manner adverse to the holders of the Shares may be made and neither Parent nor Merger Subsidiary may extend the Offer, except in accordance with Section 2.01(c).

(b) On the date of commencement of the Offer, Parent and Merger Subsidiary shall file with the SEC a Tender Offer Statement on Schedule TO (as amended and supplemented from time to time, the “Schedule TO”), which shall comply in all material respects with the provisions of applicable federal securities Laws, and shall contain the offer to purchase relating to the Offer and forms of the related letter of transmittal and other appropriate documents (which documents, as amended or supplemented from time to time, are referred to herein collectively as the “Offer Documents”). The Parent and the Merger Subsidiary further agree to disseminate the Offer Documents to holders of Shares as and to the extent required by applicable federal securities Laws. In conducting the

Offer, the Parent and the Merger Subsidiary shall comply in all material respects with the provisions of the Exchange Act and any other applicable Laws necessary to be complied with in connection with the Offer. The Company shall promptly furnish to Parent and Merger Subsidiary all information concerning the Company and its Subsidiaries and the Company’s stockholders that may be required or reasonably requested in connection with any action contemplated by this Section 2.01. The Company and its counsel shall be given a reasonable opportunity to review and comment on the Offer Documents prior to their filing with the SEC. Parent and Merger Subsidiary agree to provide the Company, and to consult with the Company and its counsel regarding, any comments that may be received from the SEC or its staff (whether written or oral) with respect to the Offer Documents promptly after receipt thereof and any responses thereto. Each of Parent, Merger Subsidiary and the Company agrees promptly to correct any information provided by it for use in the Offer Documents if and to the extent that it shall have become false or misleading in any material respect, and Parent and Merger Subsidiary further agree to take all steps necessary to cause the Offer Documents as so corrected to be filed with the SEC and be disseminated to holders of Shares, in each case, as and to the extent required by Law.

(c) The initial scheduled expiration date of the Offer shall be 20 Business Days after the date of its commencement. Notwithstanding the foregoing, Parent and Merger Subsidiary shall have the right to extend the Offer (i) from time to time if, at any scheduled or extended expiration date of the Offer, any of the conditions to the Offer set forth in Annex A shall not have been satisfied or waived; provided that if any of the conditions to the Offer are not satisfied or waived on any scheduled or extended expiration date of the Offer, Parent and Merger Subsidiary shall extend the Offer, if such condition or conditions could reasonably be expected to be satisfied prior to ten Business Days following the initial scheduled expiration date of the Offer; provided further that if the conditions set forth in clauses (x) or (y) of the first sentence of Annex A hereto are not satisfied or waived or the condition set forth in clause (z) of Annex A hereto is not satisfied or waived as a result of the occurrence of any of the events described in subparagraph (b) thereon on any scheduled expiration date of the Offer, Parent and Merger Subsidiary shall extend the Offer at the written request of the Company if such conditions or condition could reasonably be expected to be satisfied on or before July 31, 2004, (ii) for any period required by any rule, regulation, interpretation or position of the SEC or the staff thereof applicable to the Offer or any period required by applicable Law, (iii) on one or more occasions (all such occasions aggregating not more than 20 Business Days) beyond the latest expiration that would otherwise be permitted under clause (i) or (ii) of this sentence, if, on such expiration date, the number of Shares tendered (and not withdrawn) pursuant to the Offer, together with Shares then owned by Parent, represents more than 50% but less than 90% of the outstanding Shares on a fully diluted basis; provided, however, that Parent’s decision to extend the Offer in the case of this clause (iii) shall constitute a waiver of the conditions set forth in clauses (c) and (e) (excluding any wilful or intentional breach of any material obligation of the Company) on Annex A and of its right to terminate the Agreement under Sections 8.01(b), (d) (unless there has been a wilful or intentional breach of any material obligation by the Company), (i) or (j), (iv) on up to two occasions (for a period not to exceed ten Business Days on each occasion) if an Adverse Market Change shall have occurred and be continuing on the

initial or any extended expiration date of the Offer, and (v) for one or more subsequent offering periods of up to an additional 20 Business Days in the aggregate (collectively, the “Subsequent Period”) pursuant to Rule 14d-11 of the Exchange Act.

(d) Subject to the terms and conditions of the Offer and this Agreement, Merger Subsidiary shall, and Parent shall cause Merger Subsidiary to, accept for payment and pay for Shares validly tendered and not withdrawn pursuant to the Offer as soon as possible after the expiration thereof; provided that Merger Subsidiary shall immediately accept and promptly pay for all Shares as they are tendered during any Subsequent Period. Parent shall provide or cause to be provided to Merger Subsidiary on a timely basis the funds necessary to purchase any Shares that Merger Subsidiary becomes obligated to purchase pursuant to the Offer.

(e) The Offer Price may be increased by the Parent without the consent of the Company, in which case the Offer shall be extended, without the consent of the Company, as required by applicable Law.

Section 2.02 Company Actions.

The Company further represents that the Company’s financial advisor, Petrie Parkman, has delivered to the Board of Directors of the Company an opinion to the effect that, as of the date of such opinion, the consideration to be received by the holders of Shares (other than Parent and Merger Subsidiary) in the Offer and the Merger is fair to such holders from a financial point of view.

recommendation in accordance with the provisions of Section 6.03 and represents that it has obtained all necessary consents to permit the inclusion of the fairness opinion of Petrie Parkman in the Schedule 14D-9 and the Proxy Statement so long as such inclusion is in form and substance reasonably satisfactory to Petrie Parkman and its counsel. The Company hereby represents and warrants that it has been advised that each of its directors and executive officers intends to tender pursuant to the Offer any and all Shares they own beneficially or of record.

(b) The Company shall file with the SEC on the date of commencement of the Offer a Solicitation/Recommendation Statement on Schedule 14D-9 (as amended and supplemented from time to time, the “Schedule 14D-9”) that shall reflect, subject to the provisions of Section 6.03, the recommendation of the Company’s Board of Directors referred to above, and shall disseminate the Schedule 14D-9 to stockholders of the Company as required by Rule 14D-9 promulgated under the Exchange Act. To the extent practicable, the Company shall cooperate with Parent and Merger Subsidiary in mailing or otherwise disseminating the Schedule 14D-9 with the appropriate Offer Documents to the Company’s stockholders.

Section 2.03 Board Representation.

(a) Subject to applicable Law and to the extent permitted by the NYSE, promptly upon the acceptance for payment of any Shares pursuant to the Offer, Parent shall be entitled to designate such number of directors, rounded up to the next whole number, to serve on the Board of Directors of the Company as will give Merger Subsidiary representation on the Board of Directors of the Company equal to the product of (i) the total number of directors on the Board of Directors (giving effect to the election of any additional directors pursuant to this Section) and (ii) the percentage that the number of Shares beneficially owned by Parent and/or Merger Subsidiary (including Shares accepted for payment) bears to the number of Shares outstanding. The Company shall take all actions necessary to cause Parent’s designees to be elected or appointed to the Company’s Board of Directors, including increasing the size of the Board of Directors and/or securing the resignations of incumbent directors (including, if necessary, to ensure that a sufficient number of independent directors are serving on the Board of Directors of the Company in order to satisfy the NYSE listing requirements). Unless waived in writing by Parent, the Company shall, prior to the expiration of the Offer, deliver to Parent such resignations of directors conditioned upon acceptance of Shares for payment and evidence of the valid election of Parent’s designees to the Company’s Board of Directors conditioned upon acceptance of Shares for payment so as to effect the provisions of this Section 2.03(a). Subject to applicable Law, the Company shall cause individuals designated by Parent to constitute the same percentage as is on the entire Board of Directors of the Company (after giving effect to this Section 2.03(a)) to be on (i) each committee of the Board of Directors of the Company and (ii) each Board of Directors and each committee thereof of each Subsidiary of the Company. The Company’s obligations to appoint designees to its Board of Directors shall be subject to compliance with Section 14(f) of the Exchange Act. At the request of Parent, the Company shall promptly take, at its expense, all actions required pursuant to Section 14(f) and Rule 14f-1 under the Exchange Act in order to fulfil its obligations under this Section 2.03(a) and shall include in the Schedule 14D-9 or otherwise timely mail to its stockholders all necessary information to comply therewith. Parent will supply to the Company, and be solely responsible for, all information with respect to itself and its officers, directors and Affiliates required by Section 14(f) and Rule 14f-1 under the Exchange Act.

(b) Notwithstanding the provisions of Section 2.03(a), following the election or appointment of Parent’s designees pursuant to Section 2.03(a) and until the Effective Time, the Company shall use its commercially reasonable efforts to cause its Board of Directors to have at least two directors who are directors on the date hereof and who are not Affiliates, stockholders or employees of Parent or any of its Subsidiaries (the “Independent Directors”); provided that if any Independent Directors cease to be directors for any reason whatsoever, the remaining Independent Directors (or Independent Director, if there is only one remaining) shall be entitled to designate any other Person(s) who shall not be an Affiliate, stockholder or employee of Parent or any of its Subsidiaries to fill such vacancies and such Person(s) shall be deemed to be Independent Director(s) for purposes of this Agreement; provided that the remaining Independent Directors shall fill such vacancies as soon as practicable, but in any event

within ten Business Days, and further provided that if no such Independent Director is appointed in such time period, Parent shall designate such Independent Director(s), provided further that if no Independent Director then remains, the other directors shall designate two Persons who shall not be Affiliates, stockholders or employees of Parent or any of its Subsidiaries to fill such vacancies and such Persons shall be deemed to be Independent Directors for purposes of this Agreement. In all cases, the selection of any Independent Directors who are not directors on the date hereof shall be subject to the approval of Parent, not to be unreasonably withheld or delayed.

(c) Following the election or appointment of Parent’s designees pursuant to Section 2.03(a) and until the Effective Time, the approval of a majority of the Independent Directors shall be required to authorize (and such authorization shall constitute the authorization of the Board of Directors and no other action on the part of the Company, including any action by any other director of the Company, shall be required to authorize) any termination of this Agreement by the Company, any amendment of this Agreement requiring action by the Board of Directors, any extension of time for performance of any obligation or action hereunder by Parent or Merger Subsidiary and any enforcement of or any waiver of compliance with any of the agreements or conditions contained herein for the benefit of the Company, any action to seek to enforce any obligations of Parent or Merger Subsidiary under this Agreement or any other action by the Company’s Board of Directors under or in connection with this Agreement. The Independent Directors shall have full power solely with respect to the matters set forth in the previous sentence to be approved by the Independent Directors and in connection herewith the Independent Directors shall be authorized, on behalf of and at the expense of the Company, to retain one law firm and other advisors.

Section 3.04 Directors and Officers.

(a) The Company shall take all requisite action so that the directors of Merger Subsidiary immediately prior to the Effective Time shall be, from and after the Effective Time, the directors of the Surviving Corporation until their successors are duly elected and qualified or until their earlier death, resignation or removal in accordance with the Surviving Charter, the Surviving Bylaws and the DGCL.

(b) The officers of the Company immediately prior to the Effective Time shall be, from and after the Effective Time, the officers of the Surviving Corporation until their successors are duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Surviving Charter, the Surviving Bylaws and the DGCL.

Section 3.05 Additional Actions.

If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any further deeds, assignments or assurances in Law or any other acts are necessary or desirable to (a) vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of the Company or (b) otherwise carry out the provisions of this Agreement, the Company and its officers and directors shall be deemed to have granted to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such deeds, assignments or assurances in Law and to take all acts necessary, proper or desirable to vest, perfect or confirm title to and possession of such

Section 3.06 Conversion of Shares.

At the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Subsidiary, the Company or the holders of any of the following securities:

(b) each issued and outstanding Share other than (i) Shares referred to in Section 3.06(a) and (ii) Dissenting Shares, shall be converted into the right to receive an amount in cash, without interest, equal to the Offer Price (the “Merger Consideration”). At the Effective Time, all such Shares shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such Shares immediately prior to the Effective Time shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration, without interest; and

(c) each share of capital stock of Merger Subsidiary issued and outstanding immediately prior to the Effective Time shall be converted into 17,000 fully paid and nonassessable shares of common stock, par value $.01 per share, of the Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Surviving Corporation.

Section 3.07 Surrender and Payment.

(a) Prior to the Effective Time, Parent shall appoint a bank or trust company to act as disbursing agent (the “Disbursing Agent”) for the payment of Merger Consideration upon surrender of certificates representing the Shares. Parent will enter into a disbursing agent agreement with the Disbursing Agent, and at such times, and from time to time, as the Disbursing Agent requires funds to make the payments pursuant to Section 3.06(b), Parent shall deposit or cause to be deposited with the Disbursing Agent cash in an aggregate amount necessary to make the payments pursuant to Section 3.06(b) to holders of Shares (such amounts being hereinafter referred to as the “Exchange Fund”). The Disbursing Agent shall invest the Exchange Fund as directed by Parent; provided that such investments shall be (i) direct obligations of the United States of America, (ii) obligations for which the full faith and credit of the United States of America is pledged to provide for the payment of principal and interest, or (iii) commercial paper rated the highest quality by either Moody’s Investors Services, Inc. or Standard & Poor’s Corporation; provided further that no loss thereon or thereof shall affect the amounts payable to holders of Shares pursuant to Section 3.06(b). Any interest

and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable under Section 3.06(b) shall be promptly paid to Parent.

(b) Merger Subsidiary shall instruct the Disbursing Agent to mail promptly after the Effective Time, but in no event later than the fifth Business Day thereafter, to each person who was a record holder as of the Effective Time of an outstanding certificate or certificates which immediately prior to the Effective Time represented Shares (the “Certificates”), and whose Shares were converted into the right to receive Merger Consideration pursuant to Section 3.06(b), a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Disbursing Agent) and instructions for use in effecting the surrender of the Certificates in exchange for payment of the Merger Consideration. Upon surrender of a Certificate to the Disbursing Agent for cancellation, together with such letter of transmittal duly executed and such other documents as may be reasonably required by the Disbursing Agent, the holder of such Certificate shall be entitled to receive in exchange therefor the Merger Consideration payable in respect of that Certificate, less any required withholding of Taxes, and such Certificate shall forthwith be cancelled. No interest will be paid or accrued on the cash payable upon the surrender of the Certificates.

(c) If payment is to be made to a person other than the person in whose name the Certificate surrendered is registered, it shall be a condition of payment that the Certificate so surrendered be properly endorsed or otherwise be in proper form for transfer and that the person requesting such payment pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of the Certificate surrendered or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not applicable.

(d) Until surrendered in accordance with the provisions of this Section 3.07, each Certificate (other than Certificates representing Shares owned by Parent, Merger Subsidiary or any other subsidiary of Parent, Shares held by the Company and Dissenting Shares) shall represent for all purposes, from and after the Effective Time, only the right to receive the applicable Merger Consideration.

(e) At and after the Effective Time, there shall be no registration of transfers of Shares which were outstanding immediately prior to the Effective Time on the stock transfer books of the Surviving Corporation. From and after the Effective Time, the holders of Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Shares except as otherwise provided in this Agreement or by applicable Law. The Merger Consideration paid upon the surrender of Certificates in accordance with the terms of this Article III shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares previously represented by such Certificates. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, such Certificates shall represent the right to receive the Merger Consideration as provided in this Article III. At the close of business on the day of the Effective Time the stock ledger of the Company shall be closed.

(f) Any portion of the Merger Consideration made available to the Disbursing Agent to pay for Shares for which appraisal rights have been perfected shall be returned to Parent upon demand. At any time more than twelve months after the Effective Time, the Disbursing Agent shall upon demand of Parent deliver to it any funds which had been made available to the Disbursing Agent and not disbursed in exchange for Certificates (including all interest and other income received by the Disbursing Agent in respect of all such funds). Thereafter, holders of Certificates shall look only to the Surviving Corporation (subject to the terms of this Agreement, abandoned property, escheat and other similar Laws) as general creditors thereof with respect to any Merger Consideration that may be payable, without interest, upon due surrender of the Certificates held by them. Any amounts remaining unclaimed immediately prior to such time when such amounts would otherwise escheat or become the property of any governmental unit or agency, shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto. Notwithstanding the foregoing, none of Parent, Merger Subsidiary, the Company, the Surviving Corporation or the Disbursing Agent shall be liable to any holder of a Certificate for any Merger Consideration delivered in respect of such Certificate of Shares to a public official pursuant to any abandoned property, escheat or other similar Law.

Section 3.08 Company Stock Options and Company Warrants.

(a) The Company represents and warrants that each option to acquire Shares granted under any Company Stock Plan or any other agreement (each, a “Company Stock Option”) automatically becomes fully vested and exercisable upon consummation of the Offer (the “Trigger Event”) pursuant to the terms of the Company Stock Plans without any action on the part of the Company, Parent, Merger Subsidiary or the holder of any such Company Stock Option. At the Effective Time, each Company Stock Option outstanding immediately prior to the Effective Time, without any action on the part of the Company, Parent, Merger Subsidiary or the holder of any such Company Stock Option, shall be converted into the right to receive an amount in cash, without interest, equal to (a) the Option Consideration multiplied by (b) the aggregate number of Shares into which the applicable Company Stock Option was exercisable immediately prior to the Effective Time. Any payment made pursuant to this Section 3.08(a) to the holder of any Company Stock Option shall be reduced by any income or employment Tax withholding required under (i) the Code, (ii) any applicable state, local or foreign Tax Laws or (iii) any other applicable Laws. To the extent that any amounts are so withheld, those amounts shall be treated as having been paid to the holder of that Company Stock Option for all purposes under this Agreement. The Company shall make the payments in respect of the Company Stock Options as promptly as practicable following the cancellation of such Company Stock Options as contemplated by this Section 3.08(a) by checks payable to the holders of such Company Stock Options unless the aggregate amount payable to a particular individual exceeds $500,000, in which event payment shall be made by wire transfer of immediate available funds upon receipt by the Company of written payment instructions from the relevant option holder. Upon written notice from the Company, Parent shall cause Merger Subsidiary to pay to the Company an amount in cash sufficient to fund the Company’s payment obligation under this Section 3.08(a) as such amounts are paid (such

amount to be set forth in such written notice). The Company shall take all requisite action so that, immediately following such payment, each Company Stock Option shall be cancelled and all Company Stock Plans shall be terminated. The Company shall not grant any additional stock options or other stock-based compensation under the Company Stock Plans or otherwise from and after the date hereof.

(b) Prior to the Effective Time, the Board of Directors of the Company, or an appropriate committee of non-employee directors of Parent, shall adopt a resolution consistent with the interpretive guidance of the SEC so that the disposition by any officer or director of the Company who is a covered person of the Company (if any) for purposes of Section 16 under the Exchange Act (“Section 16”) of Shares or Company Stock Options pursuant to this Agreement and the Merger shall be an exempt transaction for purposes of Section 16.

(c) At the Effective Time, each Company Warrant outstanding immediately prior to the Effective Time, without any action on the part of the Company, Parent, Merger Subsidiary or the holder of any such Company Warrant, shall be converted into the right to receive an amount in cash, without interest, equal to (a) the Warrant Consideration multiplied by (b) the aggregate number of Shares into which the applicable Company Warrant was exercisable immediately prior to the Effective Time. Any payment made pursuant to this Section 3.08(c) to the holder of any Company Warrant shall be reduced by any income Tax withholding required under (i) the Code, (ii) any applicable state, local or foreign Tax Laws or (iii) any other applicable Laws. To the extent that any amounts are so withheld, those amounts shall be treated as having been paid to the holder of that Company Warrant for all purposes under this Agreement. The Company shall make the payments in respect of the Company Warrants as promptly as practicable following the cancellation of such Company Warrants as contemplated by this Section 3.08(c) by wire transfer of immediate available funds upon receipt by the Company of written payment instructions from the relevant warrant holder and the surrender of such Company Warrant duly endorsed to the Company. Upon written notice from the Company, Parent shall cause Merger Subsidiary to pay to the Company an amount in cash sufficient to fund the Company’s payment obligation under this Section 3.08(c) as such amounts are paid (such amount to be set forth in such written notice). The Company shall take all requisite action so that, immediately following such payment, each Company Warrant shall be cancelled and all related agreements shall be terminated. The Company shall not grant any additional warrants, options or similar rights from and after the date hereof.

Section 3.09 Dissenting Shares.

(a) Notwithstanding anything in this Agreement to the contrary, Shares that are held by any record holder who has not voted in favor of the Merger or consented thereto in writing and who has demanded appraisal rights in accordance with Section 262 of the DGCL (the “Dissenting Shares”) shall not be converted into the right to receive the Merger Consideration but shall become the right to receive such consideration as may be determined to be due in respect of such Dissenting Shares pursuant to the DGCL; provided, however, that any holder of Dissenting Shares who shall have failed to perfect

or shall have withdrawn or lost his rights to appraisal of such Dissenting Shares, in each case under the DGCL, shall forfeit the right to appraisal of such Dissenting Shares, and such Dissenting Shares shall be deemed to have been converted into the right to receive, as of the Effective Time, the Merger Consideration without interest. Notwithstanding anything to the contrary contained in this Section 3.09, if the Merger is rescinded or abandoned, then the right of any stockholder to be paid the fair value of such stockholder’s Dissenting Shares shall cease. The Surviving Corporation shall comply with all of its obligations under the DGCL with respect to holders of Dissenting Shares.

(b) The Company shall give Parent (i) prompt written notice of any demands for appraisal, any withdrawals of such demands received by the Company and any other related instruments served pursuant to the DGCL and received by the Company, and (ii) the opportunity to direct and participate in all negotiations and proceedings with respect to demands for appraisal under the DGCL. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any demands for appraisal or negotiate, offer to settle or settle any such demands.

Section 3.10 Adjustments.

If during the period between the date of this Agreement and the Effective Time, any change in the outstanding Shares shall occur, including by reason of any reclassification, recapitalization, stock dividend, stock split or combination, exchange or readjustment of Shares, or any stock dividend thereon with a record date during such period, the Offer Price, the Merger Consideration and any other amounts payable pursuant to this Agreement, as the case may be, shall be appropriately adjusted.

Section 3.11 Withholding Rights.

Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold, or cause the Disbursing Agent to deduct and withhold, from the consideration otherwise payable to any Person pursuant to this Article such amounts as it is required to deduct and withhold with respect to the making of such payment under any provision of federal, state, local or foreign tax Law. If the Surviving Corporation or Parent, as the case may be, so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Shares in respect of which the Surviving Corporation or Parent, as the case may be, made such deduction and withholding.

Section 3.12 Lost Certificates.

If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such Person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Disbursing Agent will pay, in exchange for such affidavit claiming such Certificate is lost, stolen or destroyed, the Merger Consideration to be paid in respect of the Shares represented by such Certificate, as contemplated by this Article.

Section 4.04 Authorization of Agreement; Board Recommendation; Required Vote.

(a) The Company has all requisite corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and, subject to any

required approval of this Agreement and the Merger by the Required Company Vote, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement by the Company and consummation by the Company of the transactions contemplated hereby have been duly and validly authorized by all necessary corporate action on the part of the Company and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the transactions contemplated hereby (other than, with respect to the Merger, the approval of this Agreement and the Merger by the Required Company Vote if required). This Agreement has been duly executed and delivered by the Company and (assuming due authorization, execution and delivery hereof by the other parties hereto) constitutes a legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms except as enforcement may be limited by applicable bankruptcy, insolvency or other Laws affecting creditor’s rights generally or by legal principles of general applicability governing the availability of equitable remedies.

(b) The Board of Directors of the Company, at a meeting duly called and held on May 21, 2004, has by unanimous approval of all directors determined that this Agreement, the Offer and the Merger are advisable and in the best interest of the Company’s stockholders and resolved to recommend that the holders of Shares accept the Offer, tender their Shares and, if required by applicable Law, approve this Agreement and the Merger. If required by applicable Law, the affirmative vote of the holders of at least a majority of the issued and outstanding Shares to approve this Agreement and the Merger (the “Required Company Vote”) is the only vote of holders of Shares or other securities (equity or otherwise) of the Company necessary to consummate the Merger.

Section 4.05 Approvals.

The execution and delivery of this Agreement does not, and consummation of the transactions contemplated hereby will not, require the Company or any of its Subsidiaries to obtain any Authorization or other approval of or from, or to make any filing with or notification to, any Governmental Authority or third Person, except (a) for the applicable requirements, if any, of the Exchange Act, the Competition Act, the Investment Canada Act, state securities or “blue sky” Laws, and the filing and recordation of the Certificate of Merger as required by the DGCL, (b) as set forth in Section 4.05 of the Company’s Disclosure Letter, (c) if required by applicable Law approval of this Agreement and the Merger by the Required Company Vote, and (d) consents, authorizations, permits, actions by, filings or notifications that are customarily obtained or made following the transfer of interests in oil and gas properties and (v) such other consents, approvals, authorizations, permits, actions, filings or notifications, the failure of which to be made or obtained, individually or in the aggregate, would not be expected to have a material effect on the ongoing value, business or operations of the Company and its Subsidiaries, taken as a whole. The Company’s Board of Directors has determined that the total fair market value of the reserves of oil, natural gas, shale or tar sands, or rights to reserves of oil, natural gas, shale or tar sands together with associated exploration or production assets of the Company and its Subsidiaries does not exceed $500 million and the fair market value of all of the assets of the Company and its Subsidiaries other than their reserves of oil, natural gas, shale or tar sands, or rights to reserves of oil, natural gas, shale or tar sands and associated exploration or production

assets does not exceed $50 million (with such determinations made in accordance with Section 802.3 promulgated under the HSR Act).

Section 4.06 No Violation.

Assuming that the Authorizations, filings and notifications described in Section 4.05 have been obtained or made, except as set forth in Section 4.06 of the Company’s Disclosure Letter, the execution and delivery by the Company of this Agreement does not and consummation of the transactions contemplated by this Agreement will not (a) conflict with, result in any violation or breach of, or cause a default (or an event that with notice, lapse of time or otherwise would become a default) under, (i) any Law, Regulation or Order applicable to the Company or any of its Subsidiaries, (ii) the Certificate of Incorporation or Bylaws of the Company or (iii) the organizational documents of the Company’s Subsidiaries or (b) conflict with, result in any violation or breach of, or cause a default (or an event that with notice, lapse of time or otherwise would become a default) under, or give to others any right of termination, cancellation, amendment or acceleration of, or require a payment under, or result in the loss of any benefit under, or in the creation of a Lien on any of the properties or assets of the Company or any of its Subsidiaries pursuant to, any note, bond, mortgage, indenture, deed of trust, lease, license, permit, franchise, contract or agreement to which the Company or any of its Subsidiaries is a party or by which it or any of its Subsidiaries or its or their respective properties or assets is bound, except in the case of matters described in clauses (a)(i) and (b) of this Section 4.06 that, individually or in the aggregate, would not have a Company Material Adverse Effect.

(c) in the event (i) the Merger Agreement is terminated pursuant to Sections 8.01(e), 8.01(f) or 8.01(h) of the Merger Agreement (in the case of 8.01(h), only if the Minimum Condition had not been satisfied and an Acquisition Proposal existed or had been previously announced prior to the termination of the Merger Agreement), and (ii) within nine months following such termination the Stockholder (A) receives consideration in respect of some or all of the Subject Securities in connection with the consummation of an Acquisition Proposal or (B) makes a bona fide sale of some or all of its Subject Securities to a third party, to pay Parent an amount in immediately available funds by wire transfer to a bank account designated by Parent equal to 30.78% multiplied by the difference between (i) the aggregate fair value of the consideration received by the Stockholder pursuant to such Acquisition Proposal or third party sale, as applicable, and (ii) the aggregate cash consideration that would have been received by the Stockholder pursuant to the Offer based on the initial Offer Price of $10.60 per share with respect to the Subject Securities sold in connection with such Acquisition Proposal or third party sale, as applicable (or in the case of Subject Securities other than Company Common Stock, the amount of cash consideration that would have been received had such Subject Securities been exercised for Company Common Stock prior to the expiration of the Offer net of the applicable exercise price). Such payment to Parent shall be made as follows: (i) if the consideration paid to the Stockholder is cash, immediately following the consummation of such Acquisition Proposal or third party sale or (ii) if the consideration paid to the Stockholder consists of marketable securities, within ten Business Days following consummation of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of marketable securities, the fair value of such securities shall be determined based on the closing market price of such securities on the principal securities exchange or other trading market for such securities on the Business Day immediately preceding the closing date of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of non-marketable securities or other property, the fair value of such consideration shall be determined by a

nationally recognized investment banking firm selected by Stockholder that has not provided services to Stockholder or its affiliates during the prior five years and is reasonably acceptable to Parent as soon as possible after the closing of such Acquisition Proposal, and the fair value determination of such firm shall be binding upon the parties. In the event the consideration received by the Stockholder consists of any non-marketable securities or other property, the Stockholder shall pay Parent its good faith estimate (the “Estimated Payment”) of the amount owed pursuant to this Section 3(c) in respect of such consideration within ten Business Days following consummation of the Acquisition Proposal or third party sale, as applicable. Following the determination of the fair value of any non-marketable securities or other property (as described above), the Stockholder or Parent shall promptly pay the other party in immediately available funds by wire transfer to a bank account designated by the payee party an amount equal to the difference between the Estimated Payment and finally determined amount owing to Parent under Section 3(c) (with Parent receiving payment to the extent such amount exceeds the Estimated Payment and the Stockholder receiving payment to the extent the Estimated Payment exceeds such amount). In addition, if Stockholder makes a bona fide sale of some or all of its Subject Securities to a third party at a time when the Company is then a party to an agreement that provides for an Acquisition Proposal (which agreement has not then been terminated pursuant to its terms), then if such Acquisition Proposal is consummated (or if that Acquisition Proposal is not consummated because another Acquisition Proposal supplants that Acquisition Proposal because the Company determines such Acquisition Proposal is superior, then if such subsequent Acquisition Proposal is consummated) within nine months following the termination of the Merger Agreement, Stockholder shall pay to Parent within ten Business Days of the consummation of such Acquisition Proposal the Top-up Amount. The Top-up Amount shall be equal to 30.78% multiplied by the difference between (i) the aggregate fair value of the consideration that would have been received by the Stockholder pursuant to such Acquisition Proposal in respect of the Subject Securities that were sold in such bona fide sale to a third party and (ii) the aggregate fair value of the consideration received by such Stockholder in connection with such bona fide sale. For the avoidance of doubt, Parent and Merger Subsidiary acknowledge and agree that because of the undertaking by Stockholder in this Section 3(c) to disgorge a portion of the improved price of such Acquisition Proposal or Superior Proposal over the Offer Price (i) on and after the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any actions necessary to consummate an Acquisition Proposal or Superior Proposal in lieu of the Offer, including, without limitation, withdrawing its shares from the Offer and voting in favor of such other Acquisition Proposal or Superior Proposal and (ii) prior to the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any action except those prohibited by this Agreement, including the prohibitions referred to in Section 5 of this Agreement, and any of the Stockholder’s designees or affiliates who is a director or officer of the Company may expressly take such actions as are contemplated by the last two sentences of section 5 in connection with an Acquisition Proposal or Superior Proposal; and

(d) that it will not enter into an agreement, arrangement or understanding (whether written or oral) with WILP or Dimeling Schreiber and Park Reorganization Fund II, L.P. or their direct or indirect owners (and will not permit its direct or indirect

owners to enter into any such agreements, arrangements or understandings) that affects or otherwise modifies the sharing agreement contemplated by Section 3(c) hereof or any other provisions of this Agreement in a manner adverse to Parent or Merger Subsidiary without the prior written consent of Parent.

Section 4. Voting of Subject Securities.

(a) Stockholder Agreement. The Stockholder agrees that, during the period from the date of this Agreement until the Expiration Date:

(i) at any meeting of stockholders of the Company, however called, and at every adjournment or postponement thereof, the Stockholder shall (A) appear at the meeting, or otherwise cause all shares of Company Common Stock Owned by the Stockholder to be counted as present thereat for purposes of establishing a quorum, (B) vote or cause all shares of Company Common Stock Owned by the Stockholder to be voted in favor of the approval and adoption of the Merger Agreement and the approval of the Merger and (C) vote or cause all shares of Company Common Stock Owned by the Stockholder to be voted, against (1) any Acquisition Proposal (other than one by Parent or Merger Subsidiary) and (2) any amendment of the Company’s Certificate of Incorporation or Bylaws or other proposal, action or transaction involving the Company or any of its subsidiaries or any of its stockholders, which amendment or other proposal, action or transaction could reasonably be expected to prevent or materially impede or delay the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement or this Agreement or to deprive Parent or Merger Subsidiary of any material portion of the benefits anticipated by Parent or Merger Subsidiary to be received from the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement or this Agreement, or change in any manner the voting rights of Company Common Stock presented to the stockholders of the Company or in respect of which vote or consent of the stockholders is requested or sought, unless such transaction has been approved in advance by Parent or Merger Subsidiary; and

(ii) in the event written consents are solicited or otherwise sought from stockholders of the Company with respect to the approval or adoption of the Merger Agreement or with respect to the approval of the Merger, the Stockholder shall cause to be validly executed, with respect to all shares of Company Common Stock Owned by the Stockholder as of the record date fixed for the consent to the proposed action, a written consent or written consents to such proposed action.

(b) No Exercise Requirement; Merger Agreement Treatment. Nothing in this Agreement shall obligate the Stockholder to exercise or convert any options or other rights to acquire shares of Company Common Stock that are Owned by the Stockholder. The Stockholder shall not exercise any Company Warrants prior to the expiration of the Offer unless the Stockholder promptly tenders the Company Common Stock received and does not withdraw such Company Common Stock from the Offer; it being expressly understood that this obligation shall cease immediately upon the Expiration Date. The

Stockholder shall not exercise any Company Warrants after the expiration of the Offer and prior to the Expiration Date if such exercise would cause Merger Subsidiary to own fewer than a majority of the outstanding shares of Company Common Stock (determined on a fully diluted basis excluding Company Warrants that are not then proposed to be exercised). The Stockholder hereby consents to the conversion of the Company Warrants in connection with the Merger as provided in Section 3.08(c) of the Merger Agreement.

Section 5. No Solicitation.

During the period from the date of this Stockholder Agreement through the Expiration Date, the Stockholder shall not, nor shall the Stockholder authorize or permit any representative of the Stockholder to, directly or indirectly take any action prohibited by Section 6.03 of the Merger Agreement. Nothing contained in this Section 5 shall prevent any person affiliated with the Stockholder who is a director or officer of the Company or designated by the Stockholder as a director of officer of the Company, when acting in his capacity as a director or officer of the Company, from exercising his fiduciary duties as a director or officer of the Company including, without limitation, taking any actions permitted under Section 6.03 of the Merger Agreement. In addition, nothing in this Agreement shall (or require the Stockholder to attempt to) limit or restrict any designee or affiliate of the Stockholder who is a director or officer of the Company from acting in such capacity or voting in such person’s sole discretion on any matter (it being understood that this Agreement shall apply to the Stockholder solely in the Stockholder’s capacity as a stockholder of the Company). The Stockholder shall have no liability to Parent, Merger Subsidiary or any of their respective affiliates under this Agreement as a result of any action or inaction by any designee or affiliate of Stockholder who is a director or officer of the Company, in either case serving on the Company’s board of directors or as an officer of the Company and acting in such person’s capacity as a director, officer or fiduciary of the Company.

Schedule I - 1

STOCKHOLDER AGREEMENT

RECITALS

The Stockholder is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of such number of securities of the Company as indicated on the Schedule I to this Agreement; and

In order to induce Parent and Merger Subsidiary to enter into the Merger Agreement, the Stockholder is entering into this Agreement.

NOW, THEREFORE, intending to be legally bound, the parties hereto agree as follows:

Section 1. Certain Definitions.

For purposes of this Agreement:

(a) “Company Common Stock” shall mean the common stock, par value $0.01 per share, of the Company.

(b) “Company Warrants” shall mean warrants to purchase 741,716 shares of Company Common Stock at an exercise price of $4.25 per share.

(i) the date upon which the Merger Agreement is validly terminated pursuant to Section 8.01 thereof;

(ii) the date on which the Parent or Merger Subsidiary shall have purchased and paid for all of the Subject Securities;

(e) “Person” shall mean any individual, corporation, limited liability company, partnership, trust or other entity, or governmental authority.

(h) Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

Section 2. Transfer of Subject Securities.

(a) Transferee of Subject Securities to be Bound by this Agreement. The Stockholder agrees that, except as may be provided herein, during the period from the date of this Agreement through the Expiration Date, the Stockholder shall not cause or permit any Transfer of any of the Subject Securities to be effected; provided, that nothing in this Agreement shall prohibit the Stockholder from Transferring Subject Securities to Merger Subsidiary pursuant to Section 3 hereof. Parent and Merger Subsidiary acknowledge and agree that the Stockholder has previously entered into a voting agreement with Wiser Investment Company, LLC (“WIC”) granting WIC certain voting rights with respect to the Subject Securities and that WIC and Stockholder have in

connection with a loan previously pledged Subject Securities to Management Resources Group, LLC (“MRG”) pursuant to a pledge agreement previously entered into by such parties and that the existence of such voting and pledge agreements and the continuing compliance by the parties thereto with such agreements shall not be deemed a Transfer in contravention of this Section 2(a); provided, however, that notwithstanding the foregoing no Transfer shall be permitted under such agreements if such Transfer would adversely affect the right and power of the Stockholder to tender the Subject Securities in the Offer or otherwise comply with its obligations under this Agreement unless the transferee in any such Transfer shall (i) execute a counterpart of this Agreement and (ii) agree to hold such Subject Securities subject to all of the terms and provisions of this Agreement and be treated as a Stockholder hereunder. If Section 3(c) applies, the Stockholder agrees that during the period from the Expiration Date through the date the provisions of Section 3(c) terminate pursuant to Section 9(m), the Stockholder shall not cause or permit any Transfer of any of the Subject Securities to be effected unless the Person to whom such Subject Securities are Transferred shall have: (i) executed a counterpart of this Agreement and (ii) agreed to hold such Subject Securities subject to the terms and provisions of Section 3(c) hereof and be treated as a Stockholder thereunder.

(b) No Transfer of Voting Rights. The Stockholder shall ensure that, except for voting agreements in favor of WIC existing on the date hereof and except for the Stockholders Agreement dated May 26, 2000 among the Company, the Stockholder and certain other stockholders of the Company (the “Stockholders Agreement”), during the period from the date of this Agreement through the Expiration Date: (a) none of the Subject Securities Owned by the Stockholder is deposited into a voting trust; and (b) no proxy is granted, and no voting agreement or similar agreement is entered into, with respect to any of the Subject Securities Owned by the Stockholder.

Section 3. Tender of Subject Securities.

The Stockholder agrees:

or, if later, on or before the fifth Business Day after such acquisition but in any event prior to the date of expiration of such Offer. The Stockholder acknowledges and agrees that the obligation of Merger Subsidiary to accept for payment and pay for any Subject Securities in the Offer is subject to the terms and conditions of the Offer (as described in the Merger Agreement). Parent and Merger Subsidiary acknowledge that the Stockholder’s obligation to sell any Subject Securities to Merger Subsidiary and the release of the Lien of MRG and termination of any voting agreement in favor of WIC is expressly conditioned upon Merger Subsidiary’s acceptance and payment for the Subject Securities in the Offer pursuant to the terms of the Offer as the same may be amended from time to time, consistent with the terms of this Agreement and the Merger Agreement;

Acquisition Proposal or third party sale, as applicable, consists of marketable securities, the fair value of such securities shall be determined based on the closing market price of such securities on the principal securities exchange or other trading market for such securities on the Business Day immediately preceding the closing date of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of non-marketable securities or other property, the fair value of such consideration shall be determined by a nationally recognized investment banking firm selected by Stockholder that has not provided services to Stockholder or its affiliates during the prior five years and is reasonably acceptable to Parent as soon as possible after the closing of such Acquisition Proposal, and the fair value determination of such firm shall be binding upon the parties. In the event the consideration received by the Stockholder consists of any non-marketable securities or other property, the Stockholder shall pay Parent its good faith estimate (the “Estimated Payment”) of the amount owed pursuant to this Section 3(c) in respect of such consideration within ten Business Days following consummation of the Acquisition Proposal or third party sale, as applicable. Following the determination of the fair value of any non-marketable securities or other property (as described above), the Stockholder or Parent shall promptly pay the other party in immediately available funds by wire transfer to a bank account designated by the payee party an amount equal to the difference between the Estimated Payment and finally determined amount owing to Parent under Section 3(c) (with Parent receiving payment to the extent such amount exceeds the Estimated Payment and the Stockholder receiving payment to the extent the Estimated Payment exceeds such amount). In addition, if Stockholder makes a bona fide sale of some or all of its Subject Securities to a third party at a time when the Company is then a party to an agreement that provides for an Acquisition Proposal (which agreement has not then been terminated pursuant to its terms), then if such Acquisition Proposal is consummated (or if that Acquisition Proposal is not consummated because another Acquisition Proposal supplants that Acquisition Proposal because the Company determines such Acquisition Proposal is superior, then if such subsequent Acquisition Proposal is consummated) within nine months following the termination of the Merger Agreement, Stockholder shall pay to Parent within ten Business Days of the consummation of such Acquisition Proposal the Top-up Amount. The Top-up Amount shall be equal to 30.78% multiplied by the difference between (i) the aggregate fair value of the consideration that would have been received by the Stockholder pursuant to such Acquisition Proposal in respect of the Subject Securities that were sold in such bona fide sale to a third party and (ii) the aggregate fair value of the consideration received by such Stockholder in connection with such bona fide sale. For the avoidance of doubt, Parent and Merger Subsidiary acknowledge and agree that because of the undertaking by Stockholder in this Section 3(c) to disgorge a portion of the improved price of such Acquisition Proposal or Superior Proposal over the Offer Price (i) on and after the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any actions necessary to consummate an Acquisition Proposal or Superior Proposal in lieu of the Offer, including, without limitation, withdrawing its shares from the Offer and voting in favor of such other Acquisition Proposal or Superior Proposal and (ii) prior to the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any action except those prohibited by this Agreement, including the prohibitions referred to in Section 5 of this Agreement, and any of the Stockholder’s designees or affiliates who is a director or officer of the Company may expressly take such actions as are contemplated by the last two sentences of section 5 in connection with an Acquisition Proposal or Superior Proposal; and

(d) that it will not enter into an agreement, arrangement or understanding (whether written or oral) with WIC or Dimeling, Schreiber and Park Reorganization Fund II, L.P. or their direct or indirect owners (and will not permit its direct or indirect owners

to enter into any such agreements, arrangements or understandings) that affects or otherwise modifies the sharing agreement contemplated by Section 3(c) hereof or any other provisions of this Agreement in a manner adverse to Parent or Merger Subsidiary without the prior written consent of Parent.

Section 4. Voting of Subject Securities.

Stockholder Agreement. The Stockholder agrees that, during the period from the date of this Agreement until the Expiration Date:

In addition, nothing in this Agreement shall (or require the Stockholder to attempt to) limit or restrict any designee or affiliate of the Stockholder who is a director or officer of the Company from acting in such capacity or voting in such person’s sole discretion on any matter (it being understood that this Agreement shall apply to the Stockholder solely in the Stockholder’s capacity as a stockholder of the Company). The Stockholder shall have no liability to Parent, Merger Subsidiary or any of their respective affiliates under this Agreement as a result of any action or inaction by any designee or affiliate of Stockholder who is a director or officer of the Company, in either case serving on the Company’s board of directors or as an officer of the Company and acting in such person’s capacity as a director, officer or fiduciary of the Company.

STOCKHOLDER AGREEMENT

RECITALS

The Stockholder is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of such number of securities of the Company as indicated on the Schedule I to this Agreement; and

In order to induce Parent and Merger Subsidiary to enter into the Merger Agreement, the Stockholder is entering into this Agreement.

NOW, THEREFORE, intending to be legally bound, the parties hereto agree as follows:

Section 1. Certain Definitions.

For purposes of this Agreement:

(a) “Company Common Stock” shall mean the common stock, par value $0.01 per share, of the Company.

(b) “Company Warrants” shall mean warrants to purchase 741,716 shares of Company Common Stock at an exercise price of $4.25 per share.

(i) the date upon which the Merger Agreement is validly terminated pursuant to Section 8.01 thereof;

(ii) the date on which the Parent or Merger Subsidiary shall have purchased and paid for all of the Subject Securities;

(iii) the date upon which the Merger becomes effective;

(iv) the date upon which the Merger Agreement is amended to reduce the Offer Price or in any other manner adverse in any material respect to the Stockholder; and

(v) the End Date.

(e) “Person” shall mean any individual, corporation, limited liability company, partnership, trust or other entity, or governmental authority.

(h) Capitalized terms not otherwise defined herein shall have the respective meanings ascribed to them in the Merger Agreement.

Section 2. Transfer of Subject Securities.

(a) Transferee of Subject Securities to be Bound by this Agreement. The Stockholder agrees that, except as may be provided herein, during the period from the date of this Agreement through the Expiration Date, the Stockholder shall not cause or permit any Transfer of any of the Subject Securities to be effected; provided, that nothing in this Agreement shall prohibit the Stockholder from Transferring Subject Securities to Merger Subsidiary pursuant to Section 3 hereof. Parent and Merger Subsidiary acknowledge and agree that the Stockholder has previously entered into a voting agreement with Wiser Investment Company, LLC (“WIC”) granting WIC certain voting

rights with respect to the Subject Securities. If Section 3(c) applies, the Stockholder agrees that during the period from the Expiration Date through the date the provisions of Section 3(c) terminate pursuant to Section 9(m), the Stockholder shall not cause or permit any Transfer of any of the Subject Securities to be effected unless the Person to whom such Subject Securities are Transferred shall have: (i) executed a counterpart of this Agreement and (ii) agreed to hold such Subject Securities subject to the terms and provisions of Section 3(c) hereof and be treated as a Stockholder thereunder.

Section 3. Tender of Subject Securities.

The Stockholder agrees:

(a) to tender the Company Common Stock Owned by the Stockholder into the Offer promptly, and in any event no later than the tenth Business Day following the commencement of the Offer, or, if any Stockholder has not received the Offer Documents by such time, within five Business Days following receipt of such documents but in any event prior to the date of expiration of such Offer, in each case, free and clear of any liens, claims, options, rights of first refusal, co-sale rights, charges or other encumbrances (collectively, “Liens”) and (ii) not to withdraw any Company Common Stock so tendered so long as there is no decrease in the Offer Price and the Offer Price is payable in cash. The Stockholder shall have no obligations or liabilities to Parent or Merger Subsidiary under this Section 3(a) at any time after the Expiration Date. If the Stockholder acquires additional Subject Securities after the date hereof, the Stockholder shall tender (or cause the record holder to tender) such Subject Securities on or before the tenth Business Day following the commencement of the Offer, or, if later, on or before the fifth Business Day after such acquisition but in any event prior to the date of expiration of such Offer. The Stockholder acknowledges and agrees that the obligation of Merger Subsidiary to accept for payment and pay for any Subject Securities in the Offer is subject to the terms and conditions of the Offer (as described in the Merger Agreement). Parent and Merger Subsidiary acknowledge that the Stockholder’s obligation to sell any Subject Securities to Merger Subsidiary and termination of any voting agreement in favor of WIC is expressly conditioned upon Merger Subsidiary’s acceptance and payment for the Subject Securities in the Offer pursuant to the terms of the Offer as the same may be amended from time to time, consistent with the terms of this Agreement and the Merger Agreement;

applicable law in connection with the transactions contemplated by the Offer and Merger Agreement, the Stockholder’s identity and ownership of the Subject Securities and the nature of the Stockholder’s commitments, arrangements and understandings under this Agreement;

(c) in the event (i) the Merger Agreement is terminated pursuant to Sections 8.01(e), 8.01(f) or 8.01(h) of the Merger Agreement (in the case of 8.01(h), only if the Minimum Condition had not been satisfied and an Acquisition Proposal existed or had been previously announced prior to the termination of the Merger Agreement), and (ii) within nine months following such termination the Stockholder (A) receives consideration in respect of some or all of the Subject Securities in connection with the consummation of an Acquisition Proposal or (B) makes a bona fide sale of some or all of its Subject Securities to a third party, to pay Parent an amount in immediately available funds by wire transfer to a bank account designated by Parent equal to 100% multiplied by the difference between (i) the aggregate fair value of the consideration received by the Stockholder pursuant to such Acquisition Proposal or third party sale, as applicable, and (ii) the aggregate cash consideration that would have been received by the Stockholder pursuant to the Offer based on the initial Offer Price of $10.60 per share with respect to the Subject Securities sold in connection with such Acquisition Proposal or third party sale, as applicable (or in the case of Subject Securities other than Company Common Stock, the amount of cash consideration that would have been received had such Subject Securities been exercised for Company Common Stock prior to the expiration of the Offer net of the applicable exercise price). Such payment to Parent shall be made as follows: (i) if the consideration paid to the Stockholder is cash, immediately following the consummation of such Acquisition Proposal or third party sale or (ii) if the consideration paid to the Stockholder consists of marketable securities, within ten Business Days following consummation of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of marketable securities, the fair value of such securities shall be determined based on the closing market price of such securities on the principal securities exchange or other trading market for such securities on the Business Day immediately preceding the closing date of such Acquisition Proposal or third party sale. In the event the consideration received by the Stockholder in respect of an Acquisition Proposal or third party sale, as applicable, consists of non-marketable securities or other property, the fair value of such consideration shall be determined by a nationally recognized investment banking firm selected by Stockholder that has not provided services to Stockholder or its affiliates during the prior five years and is reasonably acceptable to Parent as soon as possible after the closing of such Acquisition Proposal, and the fair value determination of such firm shall be binding upon the parties. In the event the consideration received by the Stockholder consists of any non-marketable securities or other property, the Stockholder shall pay Parent its good faith estimate (the “Estimated Payment”) of the amount owed pursuant to this Section 3(c) in respect of such consideration within ten Business Days following consummation of the Acquisition Proposal or third party sale, as applicable. Following the determination of the fair value of any non-marketable securities or other property (as described above), the Stockholder or Parent shall promptly pay the other party in immediately available funds by wire transfer to a bank account designated by the payee party an amount equal to the

difference between the Estimated Payment and finally determined amount owing to Parent under Section 3(c) (with Parent receiving payment to the extent such amount exceeds the Estimated Payment and the Stockholder receiving payment to the extent the Estimated Payment exceeds such amount). In addition, if Stockholder makes a bona fide sale of some or all of its Subject Securities to a third party at a time when the Company is then a party to an agreement that provides for an Acquisition Proposal (which agreement has not then been terminated pursuant to its terms), then if such Acquisition Proposal is consummated (or if that Acquisition Proposal is not consummated because another Acquisition Proposal supplants that Acquisition Proposal because the Company determines such Acquisition Proposal is superior, then if such subsequent Acquisition Proposal is consummated) within nine months following the termination of the Merger Agreement, Stockholder shall pay to Parent within ten Business Days of the consummation of such Acquisition Proposal the Top-up Amount. The Top-up Amount shall be equal to 100% multiplied by the difference between (i) the aggregate fair value of the consideration that would have been received by the Stockholder pursuant to such Acquisition Proposal in respect of the Subject Securities that were sold in such bona fide sale to a third party and (ii) the aggregate fair value of the consideration received by such Stockholder in connection with such bona fide sale. For the avoidance of doubt, Parent and Merger Subsidiary acknowledge and agree that because of the undertaking by Stockholder in this Section 3(c) to disgorge a portion of the improved price of such Acquisition Proposal or Superior Proposal over the Offer Price (i) on and after the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any actions necessary to consummate an Acquisition Proposal or Superior Proposal in lieu of the Offer, including, without limitation, withdrawing its shares from the Offer and voting in favor of such other Acquisition Proposal or Superior Proposal and (ii) prior to the termination of the Merger Agreement (or the Expiration Date, if earlier) the Stockholder may take any action except those prohibited by this Agreement, including the prohibitions referred to in Section 5 of this Agreement, and any of the Stockholder’s designees or affiliates who is a director or officer of the Company may expressly take such actions as are contemplated by the last two sentences of section 5 in connection with an Acquisition Proposal or Superior Proposal; and

(d) that it will not enter into an agreement, arrangement or understanding (whether written or oral) with WIC or Wiser Investors, L.P. or their direct or indirect owners (and will not permit its direct or indirect owners to enter into any such agreements, arrangements or understandings) that affects or otherwise modifies the sharing agreement contemplated by Section 3(c) hereof or any other provisions of this Agreement in a manner adverse to Parent or Merger Subsidiary without the prior written consent of Parent.

Section 4. Voting of Subject Securities.

Stockholder Agreement. The Stockholder agrees that, during the period from the date of this Agreement until the Expiration Date:

Stock Owned by the Stockholder to be counted as present thereat for purposes of establishing a quorum, (B) vote or cause all shares of Company Common Stock Owned by the Stockholder to be voted in favor of the approval and adoption of the Merger Agreement and the approval of the Merger and (C) vote or cause all shares of Company Common Stock Owned by the Stockholder to be voted, against (1) any Acquisition Proposal (other than one by Parent or Merger Subsidiary) and (2) any amendment of the Company’s Certificate of Incorporation or Bylaws or other proposal, action or transaction involving the Company or any of its subsidiaries or any of its stockholders, which amendment or other proposal, action or transaction could reasonably be expected to prevent or materially impede or delay the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement or this Agreement or to deprive Parent or Merger Subsidiary of any material portion of the benefits anticipated by Parent or Merger Subsidiary to be received from the consummation of the Offer, the Merger or the other transactions contemplated by the Merger Agreement or this Agreement, or change in any manner the voting rights of Company Common Stock presented to the stockholders of the Company or in respect of which vote or consent of the stockholders is requested or sought, unless such transaction has been approved in advance by Parent or Merger Subsidiary; and

Section 5. No Solicitation.

Section 6. Representations and Warranties of Stockholders.

The Stockholder hereby represents and warrants to Parent and Merger Subsidiary as follows:

(i) The execution and delivery of this Agreement by the Stockholder does not, and the performance of this Agreement by the Stockholder will not: (A) conflict with or violate any certificate of incorporation or bylaws or equivalent organizational documents of the Stockholder, (B) subject to the consent of the Company (which consent of the Company has been obtained), conflict with or violate any law, rule, regulation, order, decree or judgment applicable to the Stockholder or by which the Stockholder or any of the Stockholder’s properties or assets is or may be bound or affected; or (C) result in or constitute (with or without notice or lapse of time) any breach of or default under, or give to any other Person (with or without notice or lapse of time) any right of termination, amendment, acceleration or cancellation of, or result (with or without notice or lapse of time) in the creation of any Lien on any of the Subject Securities pursuant to, any contract to which the Stockholder is a party or by which the Stockholder or any of the Stockholder’s affiliates or properties is or may be bound or affected except that the consent of the Company and WIC (which consents of the Company and WIC have been obtained), are required for any Transfer, including the execution of this Agreement.

(d) Title to Securities. As of the date of this Agreement: (a) except for the voting agreements and proxies in favor or WIC and the Stockholders Agreement, the Stockholder holds of record free and clear of any Liens the number of outstanding shares of Company Common Stock set forth under the heading “Company Common Stock Owned” on Schedule I hereto; and (b) the Stockholder does not directly or indirectly Own any shares of capital stock or other securities of the Company, or any option, warrant or other right to acquire (by purchase, conversion or otherwise) any shares of capital stock or other securities of the Company.
