Subject to the terms and conditions set forth in ---------- this Agreement, at the Effective Time, Sub will be merged with and into Canaan in accordance with the provisions of this Agreement and the OGCA. Such merger is referred to in this Agreement as the "Merger." 2.2 Effect of the Merger. Upon the effectiveness of the Merger, the -------------------- separate existence of Sub will cease and Canaan, as the surviving corporation in the Merger (the "Surviving Corporation"), will continue its corporate existence under the laws of the State of Oklahoma. The Merger will have the effects specified in this Agreement and the OGCA. 2.3 Governing Instruments, Directors and Officers of the Surviving -------------------------------------------------------------- Corporation. ----------- 2.3.1 Certificate of Incorporation. The certificate of ---------------------------- incorporation of Canaan, as in effect immediately prior to the Effective Time amended to reflect the change in the name of the Surviving Corporation as provided herein, will be the certificate of incorporation of the Surviving Corporation until duly amended in accordance with its terms and applicable law. 2.3.2 Bylaws. The bylaws of Canaan, as in effect immediately ------ prior to the Effective Time, will be the bylaws of the Surviving Corporation until duly amended in accordance with their terms and applicable law. -9- 2.3.3 Name. The name of the Surviving Corporation will be CHK ---- Acquisition, Inc., however, at the option of Parent, the name of the Surviving Corporation may be changed. 2.3.4 Directors and Officers. The directors and officers of ---------------------- Sub at the Effective Time will be the directors and officers, respectively, of the Surviving Corporation from the Effective Time until their respective successors have been duly elected or appointed in accordance with the certificate of incorporation and bylaws of the Surviving Corporation and applicable law. 2.4 Effect on Securities. As of the Effective Time, by virtue of the -------------------- Merger and without any action on the part of any holder thereof, the Sub Common Stock, the Canaan Common Stock and other Canaan securities will be treated as follows subject to the terms and conditions of this Agreement: 2.4.1 Sub Common Stock. Each share of Sub Common Stock ---------------- outstanding immediately prior to the Effective Time will be automatically converted into and become one (1) share of common stock of the Surviving Corporation on a one for one basis. As a result of the Merger the foregoing stock will represent one hundred percent (100%) of the issued and outstanding capital stock of the Surviving Corporation immediately after the Effective Time. 2.4.2 Canaan Common Stock. At the Effective Time, by virtue ------------------- of the Merger and without any action on the part of any holder thereof, each share of Canaan Common Stock that is issued and outstanding immediately prior to the Effective Time will be converted into the right to receive the Per Share Merger Consideration. Notwithstanding the foregoing, the shares of Canaan Common Stock covered by paragraph 2.4.4 of this Agreement will be controlled by such paragraph and will not receive the Per Share Merger Consideration. Each share of Canaan Common Stock, when so converted, will automatically be canceled and retired, will cease to exist and will no longer be outstanding, and the holder of any Canaan Certificate representing any such shares will cease to have any rights with respect thereto, except the right to receive the Per Share Merger Consideration upon the surrender of such Canaan Certificate in accordance with paragraph 2.5. 2.4.3 Canaan Stock Options. Section 2.4.3 of the Canaan -------------------- Disclosure Schedule lists: (a) each of the Canaan Plans; and (b) each Canaan Stock Option outstanding as of the date hereof specifying the Canaan Plan under which such Canaan Stock Option was issued, the number of shares of Canaan Common Stock covered by such Canaan Stock Option, the term of such Canaan Stock Option, the vesting schedule for such Canaan Stock Option and the exercise price for such Canaan Stock Option. Each Canaan Stock Option remaining outstanding at the Effective Time will be or become fully vested at the Effective Time. At the Effective Time, by virtue of the Merger and without any action on the part of the holder thereof, each Canaan Stock Option will -10- be canceled and each Canaan Stock Option will be converted into the right to receive, for each share of Canaan Common Stock with respect to which such Canaan Stock Option is exercisable, cash in an amount equal to the Per Share Merger Consideration, less the per share exercise price of such Canaan Stock Option. On presentation to Parent of the Canaan Stock Option or compliance with the provisions of paragraph 2.5.6 with respect thereto, the Parent will pay or cause to be paid to each holder of a Canaan Stock Option, for each share of Canaan Common Stock with respect to which such Canaan Stock Option is exercisable, cash in an amount equal to (i) the amount by which (A) the Per Share Merger Consideration, exceeds (B) the per share exercise price of such Canaan Stock Option, less (ii) amounts required to be withheld by Parent or Canaan, if any, in respect of federal taxes and other payroll withholding as a consequence of the cancellation and conversion of such Canaan Stock Option in accordance herewith. Without limiting the foregoing, except as expressly disclosed in Section 2.4.3 of the Canaan Disclosure Schedule, Canaan further hereby represents and warrants to Parent that: (i) all adjustments required to be made to the number of shares issuable or the exercise price for exercise under each of the Canaan Stock Options has been accurately made as disclosed in Section 2.4.3 of the Canaan Disclosure Schedule; and (ii) all required notices have been given to the holders of the Canaan Stock Options including, without limitation, adjustment notices. As of the Effective Time, as a result of the Merger, the provisions in any of the Canaan Plans or any other program, arrangement, option, warrant or other agreement providing for the issuance or grant of any interest in respect of the capital stock of Canaan will be canceled, cease to exist and no longer be outstanding as of the Effective Time and Canaan will take all action necessary to ensure that following the Effective Time no Person will have any right thereunder to acquire equity securities of Canaan, the Surviving Corporation or any subsidiary thereof. 2.4.4 Treasury Stock and Parent Owned Stock. At the Effective ------------------------------------- Time, by virtue of the Merger, all shares of Canaan Common Stock that are issued and held as treasury stock, if any, and all shares of Canaan Common Stock held by Parent will be canceled and retired and will cease to exist, and no Merger Consideration or other consideration will be paid or payable in exchange therefor. 2.4.5 Dissenting Stockholder Shares. Except as provided ----------------------------- herein, any issued and outstanding shares of Canaan Common Stock held by a Dissenting Stockholder will be converted into the right to receive such consideration as may be determined to be due to such Dissenting Stockholder pursuant to the OGCA. If a Dissenting Stockholder effectively withdraws the demand for appraisal or loses the right of appraisal as provided under the OGCA, the shares of Canaan Common Stock held by such Dissenting Stockholder will be deemed to be converted under paragraph 2.4.2 of this Agreement (without interest). Canaan will provide prompt notice to Parent of any written -11- demands for appraisal, withdrawals of demands for appraisal and any other instruments served pursuant to the OGCA and will provide to Parent the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the OGCA. Absent the prior written consent of Parent and Sub, Canaan will not negotiate, settle or offer to settle any demand for appraisal, provided, however that any and all payments made to settle such appraisal rights or made pursuant to the OGCA will be made solely out of Canaan assets and neither Parent nor Sub will have any liability therefor. Notwithstanding anything contained in this paragraph 2.4.5, if the Merger is rescinded or abandoned or if the stockholders of Canaan revoke the authority to effect the Merger, then the right of any Dissenting Stockholder to receive such consideration as may be determined to be due in respect of such Dissenting Stockholder's Canaan Common Stock pursuant to the OGCA will cease. 2.5 Exchange of Certificates. The exchange of Canaan Common Stock for the ------------------------ Per Share Merger Consideration will be consummated as follows: 2.5.1 Exchange Fund. At the Effective Time, Parent will deposit with ------------- the Exchange Agent, for the benefit of the holders of shares of Canaan Common Stock and for exchange in accordance with this Agreement, funds representing the Merger Consideration to be paid in exchange for shares of Canaan Common Stock pursuant to paragraph 2.5.2, less the amount of the Merger Consideration which: (i) would have been payable to Dissenting Stockholders; and (ii) will be payable with respect to the Canaan Stock Options. The funds delivered to the Exchange Agent pursuant hereto are referred to herein as the "Exchange Fund." The Exchange Agent, pursuant to irrevocable instructions consistent with the terms of this Agreement, will deliver the Per Share Merger Consideration to be paid pursuant to paragraph 2.5.2 out of the Exchange Fund, and the Exchange Fund will not be used for any other purpose whatsoever. 2.5.2 Notice and Surrender. As soon as reasonably practicable after -------------------- the Effective Time, Parent will cause the Exchange Agent to mail to each holder of record of Canaan Common Stock that, immediately prior to the Effective Time, were converted into the right to receive the Per Share Merger Consideration pursuant to paragraph 2.4.2, a letter of transmittal to be used to effect the exchange of such Canaan Common Stock for the Per Share Merger Consideration, along with instructions for using such letter of transmittal to effect such exchange. The letter of transmittal (or the instructions thereto) will specify that delivery of any Canaan Certificate will be effected, and the risk of loss and title thereto will pass, only upon delivery of such Canaan Certificate to the Exchange Agent and will be in such form and have such other provisions as Parent may reasonably specify. On surrender to the Exchange Agent of a Canaan Certificate for cancellation, together with a duly completed and executed letter of transmittal and any other required -12- documents: (a) the holder of such Canaan Certificate will be entitled to receive in exchange therefor the Per Share Merger Consideration for each share of Canaan Common Stock represented by such Canaan Certificate (after giving effect to any required withholding of Taxes); and (b) the Canaan Certificate so surrendered will forthwith be canceled. No interest will be paid or accrued on the Per Share Merger Consideration. In the event of a transfer of ownership of Canaan Common Stock that is not registered in the transfer records of Canaan, the Per Share Merger Consideration may be paid to a transferee if the Canaan Certificate representing such shares of Canaan Common Stock is presented to the Exchange Agent accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer Taxes have been paid. Until surrendered as contemplated by this paragraph 2.5.2, each Canaan Certificate will be deemed at any time after the Effective Time to represent only the right to receive on such surrender the Per Share Merger Consideration for the number of shares of Canaan Common Stock represented by such Canaan Certificate as provided in paragraph 2.4.2. 2.5.3 Full Satisfaction. Payment of the Per Share Merger ----------------- Consideration upon the surrender for exchange of shares of Canaan Common Stock in accordance with the terms hereof will be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Canaan Common Stock. After the Effective Time, there will be no further registration of transfers on the Surviving Corporation's stock transfer books of the shares of Canaan Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, a Canaan Certificate is presented to the Surviving Corporation or Parent for any reason, it will be canceled and exchanged as provided in this paragraph 2.5. 2.5.4 Unclaimed Exchange Fund. Any portion of the Exchange Fund held ----------------------- by the Exchange Agent in accordance with the terms of this paragraph 2.5 that remains unclaimed by the former stockholders of Canaan for a period of one (1) year following the Effective Time will be delivered to Parent, on demand. Thereafter, any former stockholders of Canaan who have not theretofore complied with the provisions of this paragraph 2.5 will look only to Parent for payment of their claim for the Per Share Merger Consideration for the number of shares of Canaan Common Stock owned. No interest will be paid or payable on any Per Share Merger Consideration regardless of the date actually paid. 2.5.5 No Liability. Neither Parent, Sub, Canaan, the Surviving ------------ Corporation, the Exchange Agent nor any other Person will be liable to any former holder of shares of Canaan Common Stock for any amount properly delivered to any public official pursuant to any applicable abandoned property, escheat or similar law. Any amounts remaining unclaimed by former holders of Canaan Common Stock for a period of three (3) years following the Effective Time -13- (or such earlier date immediately prior to the time at which such amounts would otherwise escheat to or become property of any Governmental Authority) will, 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. 2.5.6 Lost, Stolen or Destroyed Certificates. If any Canaan -------------------------------------- Certificate is lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Canaan Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against Parent with respect to such Canaan Certificate, the Exchange Agent will pay in exchange for such lost, stolen or destroyed Canaan Certificate the Per Share Merger Consideration deliverable with respect thereto pursuant to this Agreement. 2.5.7 Investment of Exchange Fund. The Exchange Agent will invest any --------------------------- cash included in the Exchange Fund from time to time, as directed by Parent, in short term money market assets or similar securities. Any interest and other income resulting from such investments will be payable to Parent on demand and will be the sole property of Parent. 2.6 Closing. The Closing will take place on the Closing Date at such ------- time and place as is agreed upon by Parent and Canaan. 2.7 Effective Time of the Merger. The Merger will become effective ---------------------------- immediately when the Certificate of Merger is accepted for filing by the Secretary of State of Oklahoma or at such time thereafter as is provided in the Certificate of Merger (the "Effective Time"). The Certificate of Merger will be filed on the Closing Date as soon as practicable after the Closing; provided, however, that the Certificate of Merger may be filed prior to the Closing Date or prior to the Closing so long as it provides for an Effective Time that occurs after the Closing. 2.8 Taking of Necessary or Further Action. Each of Parent, Sub and Canaan ------------------------------------- will use all reasonable efforts to take all such actions as may be necessary or appropriate in order to effectuate the Merger under the OGCA as promptly as commercially practicable. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of either Sub or Canaan, the officers and directors of the Surviving Corporation are fully authorized, in the name of the Surviving Corporation or otherwise to take, and will take all such lawful and necessary action. -14- 3.

Canaan will afford to Parent and Parent --------------------- Representatives (including, without limitation, directors, officers and employees of Parent and its Affiliates, and counsel, accountants and other professionals retained by Parent) such access, during normal business hours throughout the period prior to the Effective Time, to Canaan's books, records (including, without limitation, Tax returns and work papers of Canaan's independent auditors), properties, personnel and to such other information as Parent reasonably requests and will permit Parent to make such inspections as Parent may reasonably request and will cause the officers of all of Canaan to furnish Parent with such financial and operating data and other information with respect to the business, properties and personnel of Canaan as Parent may from time to time reasonably request, provided, however, that no investigation pursuant to this paragraph 5.2 will affect or be deemed to modify any of the representations or warranties made by Canaan in this Agreement. All information exchanged pursuant to this paragraph 5.2 will be subject to the Confidentiality Agreement. 5.3 No Solicitation. Immediately following the execution of this --------------- Agreement, Canaan: 33 5.3.1 Will (and will cause each of the Canaan Representatives to) terminate any and all existing activities, discussions and negotiations with third parties (other than Parent) with respect to any possible transaction involving any proposal to acquire all or any part of the Canaan Common Stock or all or a material portion of the assets, business or equity interests of Canaan (other than the transactions contemplated by this Agreement), whether by merger, purchase of assets, tender offer, exchange offer or otherwise. 5.3.2 Will not (and will cause the Canaan Representatives not to): (a) solicit, initiate or encourage the submission of, any offer or proposal to acquire any of the Canaan Common Stock (other than the exercise of Canaan Stock Options) or all or any material portion of the assets, business or equity interests of Canaan or any other transaction the consummation of which would or could reasonably be expected to impede, interfere with, prevent or materially delay the consummation of the Merger (other than the transactions contemplated by this Agreement), whether by merger, purchase of assets, tender offer, exchange offer or otherwise (an "Alternative Proposal"); (b) engage in negotiations or discussions concerning or provide any non-public information to any Person relating to an Alternative Proposal; or (c) agree to, approve or recommend, or otherwise facilitate any effort or attempt to make or implement, any Alternative Proposal, or withdraw its recommendation of the Merger, provided, however, that: (i) Canaan's board of directors may take and disclose to the stockholders of Canaan a position contemplated by Rules 14d-9 or 14e-2(a) promulgated under the Exchange Act with regard to an Alternative Proposal; and (ii) following receipt from a third party (without any solicitation, initiation or encouragement by Canaan or any Canaan Representatives) of a bona fide written Alternative Proposal, (x) Canaan may, upon written notice to Parent, engage in discussions or negotiations with such third party and may furnish such third party non-public information concerning Canaan, and Canaan's business, properties and assets if, prior to furnishing such information to such third party, such third party executes a confidentiality agreement not materially less favorable to Canaan than the Confidentiality Agreement (but containing provisions permitting Canaan to comply with paragraphs 5.3.2 and 5.3.3 hereof) and (y) the board of directors of Canaan may recommend such Alternative Proposal or withdraw, modify or not make its recommendation referred to in paragraph 3.18, if and only to the extent that Canaan's board of directors determines in good faith that: (1) based on the advice of Canaan's counsel, the failure to recommend such Alternative Proposal would constitute a breach of the board's fiduciary duties; and (2) based on the advice of Canaan's financial advisor, such Alternative Proposal, if consummated, would result in a transaction more favorable to Canaan's stockholders from a financial point of view than the transaction contemplated by this Agreement (a "Superior Proposal") and the Person making such Superior Proposal has the financial means, or the ability to obtain the necessary financing, to conclude such transaction. 34 5.3.3 Will promptly notify Parent after receipt by Canaan or any of the Canaan Representatives of any Alternative Proposal, any inquiries indicating that any Person is considering making or wishes to make an Alternative Proposal or any requests for nonpublic information and the terms and conditions of any proposals or offers and the status of any actions, including any discussions, taken pursuant to such Alternative Proposal. Canaan agrees that it will keep Parent informed, on a current basis, of the status and terms of any such Alternative Proposal and of any discussions or negotiations regarding same. 5.3.4 Will use Canaan's best efforts to cause each of the Irrevocable Proxies to be executed and delivered to Parent simultaneously with the execution of this Agreement, all in form and substance satisfactory to Parent and its legal counsel. Nothing in this paragraph 5.3 will permit Canaan to terminate this Agreement or to change or withdraw its recommendation except as specifically provided in paragraph 7.1. 5.4 Canaan Stockholder Meeting. As promptly as practicable after the date -------------------------- hereof, Canaan will: (a) take all action necessary in accordance with applicable law and its certificate of incorporation and bylaws to convene a meeting of its stockholders for the purpose of voting on this Agreement and the Merger; (b) distribute to its stockholders the Proxy Statement in accordance with applicable federal and state law and with its certificate of incorporation and bylaws, which Proxy Statement will contain the recommendation of the board of directors of Canaan that its stockholders approve the merger; (c) use all reasonable efforts to solicit from its stockholders proxies in favor of the approval and adoption of the Merger, this Agreement and the transactions contemplated hereby and to secure the Canaan stockholders approval; and (d) cooperate and consult with Parent with respect to each of the foregoing matters; provided, that nothing in this paragraph will prohibit the board of directors of Canaan from failing to make or from withdrawing or modifying its recommendation to Canaan's stockholders hereunder to the extent permitted by paragraph 5.3.2 of this Agreement. 5.5 Proxy Statement. With respect to the Proxy Statement, the Parties --------------- agree that: 5.5.1 Parent and Canaan will cooperate and promptly prepare a preliminary Proxy Statement and Canaan will file the preliminary Proxy Statement with the SEC as soon as practicable after the date hereof. 5.5.2 Parent and Canaan will cause the Proxy Statement, at the time it is delivered to the Canaan stockholders, to comply as to form in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the rules and regulations of the SEC thereunder. 5.5.3 Canaan hereby covenants and agrees with Parent that the Proxy Statement (at the time it is first mailed to stockholders of Canaan, at the time of the Canaan -35- Stockholder Meeting, and at the Effective Time) will not contain an untrue statement of a material fact or omit to state a 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 with respect to Canaan, or with respect to other information included in the Proxy Statement, occurs and such event is required to be described in a supplement to the Proxy Statement, such event will be so described and such supplement will be promptly prepared, filed and disseminated. 5.5.4 Parent hereby covenants and agrees with Canaan that the Proxy Statement (at the time it is first mailed to stockholders of Canaan, at the time of the Canaan Stockholder Meeting, and at the Effective Time) will not contain an untrue statement of a material fact or omit to state a 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 (provided, however, that this provision will only apply to any information contained in the Proxy Statement that was supplied by Parent specifically for inclusion therein). If, at any time prior to the Effective Time, any event with respect to Parent, or with respect to any information concerning Parent included in the Proxy Statement, occurs and such event is required to be described in a supplement to the Proxy Statement, such event will be disclosed to Canaan to be so described and such supplement will be promptly prepared, filed and disseminated. 5.5.5 Neither the Proxy Statement nor any amendment or supplement thereto will be filed or disseminated to the stockholders of Canaan without the approval of both Parent and Canaan which approval will not be unreasonably withheld. 5.6 Public Announcements. Prior to Closing, Canaan will consult with -------------------- Parent before issuing any press release or otherwise making any public statements with respect to the transactions contemplated by this Agreement and will not issue any press release or make any such public statement prior to obtaining the approval of Parent; provided, however, that such approval will not be required where such release or announcement is required by applicable law; and provided further, that Canaan may respond to inquiries by the press or others regarding the transactions contemplated by this Agreement, so long as such responses are consistent with previously issued press releases. 5.7 Notification of Certain Matters. Canaan will give prompt notice to ------------------------------- Parent of: (a) any representation or warranty of Canaan contained in this Agreement being untrue or inaccurate when made; (b) the occurrence of any event or development that would cause (or could reasonably be expected to cause) any representation or warranty of Canaan contained in this Agreement to be untrue or inaccurate on the Closing Date; or (c) any failure of Canaan to comply with or satisfy any covenant, condition, or agreement to be complied with or satisfied by it hereunder. Parent will give prompt -36- notice to Canaan of: (i) any representation or warranty of Parent contained in this Agreement being untrue or inaccurate when made; (ii) the occurrence of any event or development that would cause (or could reasonably be expected to cause) any representation or warranty of Parent contained in this Agreement to be untrue or inaccurate on the Closing Date; or (iii) any failure of Parent to comply with or satisfy any covenant, condition, or agreement to be complied with or satisfied by it hereunder. 5.8 Indemnification. From and after the Effective Time, Parent agrees --------------- that: 5.8.1 Parent will indemnify and hold harmless each present and former director and/or officer of Canaan, determined as of the Effective Time (the "Indemnified Parties"), that is made a party or threatened to be made a party to any threatened, pending or completed, action, suit, proceeding or claim, whether civil, criminal, administrative or investigative, by reason of the fact that he or she was a director or officer of Canaan prior to the Effective Time and arising out of actions or omissions of the Indemnified Party in any such capacity occurring at or prior to such Effective Time (a "Claim") against any costs or expenses (including reasonable attorneys' fees), judgments, fines, losses, claims, damages or liabilities reasonably incurred in connection with any Claim, whether asserted or claimed prior to, at or after the Effective Time, to the fullest extent that Canaan would have been permitted under Oklahoma law, the certificate of incorporation or bylaws of Canaan or written indemnification agreements in effect at the date hereof, including provisions therein relating to the advancement of expenses incurred in the defense of any action or suit. 5.8.2 Any Indemnified Party wishing to claim indemnification under paragraph 5.8.1, upon learning of any such Claim, will promptly notify Parent thereof, but the failure to so notify Parent will not relieve Parent of any liability it may have to such Indemnified Party if such failure does not materially prejudice Parent. In the event of any such Claim (whether arising before or after the Effective Time): (a) Parent will have the right to assume the defense thereof and Parent will not be liable to such Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof, except that if Parent elects not to assume such defense, the Indemnified Party may retain counsel reasonably satisfactory to Parent, and Parent will pay reasonable fees and expenses of such counsel for the Indemnified Party; provided, however, that Parent will be obligated pursuant to this paragraph 5.8.2 to pay for only one firm or counsel for all Indemnified Parties unless the use of one counsel for such Indemnified Parties would present such counsel with a conflict of interest; (b) such Indemnified Parties will cooperate in the defense of any such matter; and (c) Parent will not be liable for any settlement effected without its prior written consent, which consent will not be unreasonably withheld; and provided, further, however, that Parent will not have any obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction will -37- ultimately determine, and such determination will have become final and non-appealable, that the indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable law. If such indemnity is not available with respect to any Indemnified Party, then Parent and the Indemnified Party will contribute to the amount payable in such proportion as is appropriate to reflect relative faults and benefits, with any allocation of respective "fault" otherwise allocable to Canaan being allocated to Parent. 5.8.3 The rights of each Indemnified Party shall be in addition to any other rights such Indemnified Party may have under the certificate of incorporation or bylaws of Canaan, under the OGCA, under existing indemnification agreements, or otherwise, all of which will be assumed by the Surviving Corporation. 5.8.4 In the event Parent 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 in such consolidations or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then and in either case, proper provisions shall be made so that the successors and assigns of Parent, as case may be, shall assume the obligations as set forth in this paragraph. 5.8.5 The provisions of this paragraph 5.8 shall survive consummation of the Merger and expressly are intended to benefit each of the Indemnified Parties. 5.9 Employee and Severance Matters. ------------------------------ 5.9.1 Attached as Section 5.9 of the Canaan Disclosure Schedule is: (1) a current list of each of Canaan's employees (the "Canaan Employees"); (2) a copy of Canaan's severance policy (the "Canaan Severance Policy"); (3) a severance package table which lists the cost of all severance pay to be paid to each of the Canaan Employees; (4) a list of Canaan Employees with written employment agreements (the "Contract Employees"); (5) a list of all contract pumpers and other independent contractors (the "Independent Contractors") and a summary of the terms of such arrangements including, without limitation, any severance package; and (6) a list of each of the Canaan Employees with change in control agreements ("CIC Employees") together with the amounts and terms of such change in control agreements. 5.9.2 On or immediately prior to the Closing Date, Canaan will pay the amounts payable to the CIC Employees under the applicable change in control agreements in an amount not to exceed the amounts disclosed in the Canaan Disclosure Schedule, provided the CIC Employee has tendered the CIC Employee's resignation and executed all other documents and taken all actions required under this Agreement, the change of control agreement or the CIC Employee's employment agreement. Canaan will also pay the severance pay -38- as indicated on the severance package table to the Canaan Employees. Notwithstanding the immediately preceding sentence, Canaan will not pay such severance pay to: (1) any Canaan Employee who is not a Contract Employee and to whom Parent or Sub offers a substantially comparable job (as determined by Parent in its reasonable discretion) with equal or better base salary at such employee's current location; (2) any Contract Employee who chooses not to terminate his employment agreement with Canaan on the Closing Date; (3) any Independent Contractor who is covered by the Canaan Severance Policy and chooses not to terminate his contract with Canaan on the Closing Date; or (4) any Canaan Employee who does not execute a severance agreement in substantially the form required by the Canaan Severance Policy. With respect to any Canaan Employee who is not paid severance pay on or immediately prior to the Effective Date, all the terms and provisions of the Canaan Severance Policy and the Contract Employees' employment agreements will continue in full force and effect. Parent shall provide funding to Canaan at the Closing sufficient in amount for Canaan to make all payments required or permitted by this paragraph 5.9.2. 5.9.3 Neither Canaan nor Parent is under any obligation to retain or hire any Canaan Employee after the Effective Time. At least five (5) days before the Closing Date, Parent will provide to Canaan a list of those Canaan Employees to whom an offer of employment has been or will be made to be effective on the day after the Closing Date. On reasonable prior notice during normal business hours, Parent and the Parent Representatives will be given reasonable access to the facilities and to personnel, safety and other relevant records of Canaan (to the extent access to such records does not violate any law or the legitimate privacy rights of the Canaan Employee concerned) for the purpose of preparing for and conducting employment interviews with any Canaan Employees. Canaan will be responsible for and pay, on or before the Closing Date, any and all severance or other payments due to the Canaan Employees. 5.9.4 To the extent legally required by COBRA, for a period of 18 months following the Effective Time, Parent will, or will cause the Surviving Corporation to: (a) maintain Canaan's health benefit plans for the benefit of the continuing and terminated Canaan Employees; or (b) provide such continuing and terminated Canaan Employees with the rights and benefits of Parent's employee health benefit plans; provided, that -------- Parent will not be required to pay, or cause the Surviving Corporation to pay, the premiums for coverage under such plans for any terminated Canaan Employee. Parent will, or will cause the Surviving Corporation to, fulfill all coverage continuation obligations imposed by Section 4980B of the Code and Section 601 of ERISA for those Canaan Employees who are not retained by Parent or the Surviving Corporation. The provisions of this Section 5.9.4 are intended to be for the benefit of, and will be enforceable by, the Parties and the Canaan Employees covered by the Employee Plans at the Effective Time and their respective heirs and representatives. -39- 5.9.5 The Parent shall give to all Canaan employees who continue their employment with a Parent Company or the Surviving Corporation after the Effective Time ("Affected Employees") the opportunity to participate in all employee benefit plans maintained by Parent for its employees generally and shall give full credit for their continuous service with Canaan (including deemed service credited by Canaan) for purposes of eligibility to participate in vesting (but not benefit accruals under any defined benefit pension plan) under all employee benefit plans, programs, policies or arrangements which are maintained by Parent or any Parent Company for such Affected Employees to the same extent recognized by Canaan immediately prior to the Effective Time under any similar Canaan Employee Benefit Plans. Parent and the Surviving Corporation shall (i) waive all limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Affected Employees under any welfare benefit plan, that such employees may be eligible to participate in after the Effective Time (other than limitations or waiting periods that are already in effect with respect to any such employees under the Canaan plans and that have not been satisfied as of the Effective Time) and (ii) provide each Affected Employee with credit for any co-payments and deductibles paid prior to the Effective Time (in the calendar year of the Effective Time) and satisfying any applicable deductible or out-of-pocket requirements for the year in which the Effective Time occurred under any welfare plans that such employees are eligible to participate in after the Effective Time. For any Affected Employee who is terminated without cause within six months following the Effective Time, such Affected Employee shall receive a severance payment equal to the greater of the amount payable under the Canaan Severance Policy or any Parent severance plan or policy applicable to employees generally. 5.9.6 Canaan will use its best efforts to cause Canaan's Profit Sharing Plan and Indian Oil's 401(k) to be terminated immediately prior to the Closing with the result that all participants therein shall be 100% vested. The Parent shall cause the Surviving Corporation to take all of such action as is necessary as promptly as reasonably possible to receive IRS approval for the termination of such plans and promptly thereafter to distribute to the participants in the plans all amounts that they are entitled to receive under the plans. Parent will permit Affected Employees receiving distributions from the Canaan Profit Sharing Plan to be eligible for rollover contributions to any similar plans maintained by the Parent and will permit any outstanding plan loans that are in compliance with the applicable plan and the applicable law to be continued. 5.10 Reasonable Best Efforts. Upon the terms and subject to the conditions ----------------------- set forth in this Agreement, each of the Parties will use all reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other Parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated hereby, including: (a) the obtaining of all necessary actions -40- or non-actions, waivers, consents and approvals from Governmental Authorities and the making of all necessary registrations and filings (including filings with Governmental Authorities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity; (b) the obtaining of all necessary consents, approvals or waivers from third parties; (c) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging the Transaction Documents or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed; and (d) the execution and delivery of any additional instruments necessary to consummate the Merger and to fully carry out the purposes of the Transaction Documents. In connection with and without limiting the foregoing, the Canaan and Canaan's board of directors will: (i) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to the Merger or the Transaction Documents; and (ii) if any state takeover statute or similar statute or regulation becomes applicable to the Merger or the Transaction Documents, take all action necessary to ensure that the Merger and the other transactions contemplated hereby may be consummated as promptly as practicable on the terms contemplated by the Transaction Documents and otherwise to minimize the effect of such statute or regulation on the Merger. 5.11 Stock Options. ------------- 5.11.1 As soon as practicable following the date of this Agreement, Canaan's board of directors (or, if appropriate, any committee administering the Canaan Plans) will adopt such resolutions or take such other actions as are required to adjust the terms of all outstanding Canaan Stock Options granted under any Canaan Plan to confirm that each of the Canaan Stock Options outstanding immediately prior to the acceptance for payment of shares of Canaan Common Stock pursuant to the terms of this Agreement will be canceled, with the holder thereof becoming entitled to receive an amount of cash equal to the product of (a) the excess, if any, of (i) the Per Share Merger Consideration over (ii) the exercise price per share of Canaan Common Stock subject to such Canaan Stock Option, multiplied by (b) the number of shares of Canaan Common Stock issuable pursuant to the unexercised portion of such Canaan Stock Option. Subject to the Closing of the Merger, Parent agrees to provide any funding out of the Merger Consideration necessary to make the foregoing payments. 5.11.2 All amounts payable pursuant to paragraph 5.11.1 will be subject to any required withholding of Taxes and will be paid at or as soon as practicable at or following the Effective Time, but in any event within seven days following the Effective Time, without interest. The cancellation of a Canaan Stock Option in exchange for the cash payment described in paragraph 5.11.1 will be deemed a release of any and all rights the holder of such Canaan Stock Option had or may have had in respect thereof. -41- 5.11.3 As soon as practicable following the date of this Agreement, Canaan's board of directors (or, if appropriate, any committee administering the Canaan Plans) will take or cause to be taken such actions as are required to cause (i) the Canaan Plans to terminate as of the Effective Time and (ii) the provisions in any other plan, program or agreement providing for the issuance, transfer or grant of any capital stock of Canaan or any interest in respect of any capital stock of Canaan to be terminated as of the Effective Time. Canaan will ensure that following the Effective Time no holder of a Canaan Stock Option or any participant in any Canaan Plan or other benefit plan, program or agreement will have any right thereunder to acquire any capital stock of Canaan or the Surviving Corporation. 5.12 Stockholder Litigation. Canaan will give Parent the opportunity to ---------------------- participate in the defense or settlement of any stockholder litigation against Canaan and its directors relating to the Merger and Canaan will not agree to any settlement of such litigation without Parent's consent. 5.13 Further Assurances.

If any triggering event occurs under the Canaan Rights Agreement at any time during the period from the date of this Agreement to the Effective Time, Canaan and Parent will make such adjustment to the Per Share Merger Consideration as Canaan and Parent will mutually agree so as to preserve the economic benefits that Canaan and Parent each reasonably expected on the date of this Agreement to receive as a result of the consummation of the Merger and the other transactions. 5.15 Payment of Expenses. Except as set forth in this paragraph 5.15, all ------------------- expenses incurred in connection with this Agreement will be paid by the party incurring such expenses, whether or not the Merger is consummated.

Exhibit "A" Page 3 of 5 Pages 12. Specific Performance. The parties acknowledge and agree that performance of -------------------- their respective obligations hereunder will confer a unique benefit on the other and that a failure of performance will result in irreparable harm to the other and will not be compensable by money damages.

Restriction on Activities. During the period commencing on the date of ------------------------- this Agreement and ending on the date two (2) years after the date of this Agreement (the "Protection Period"), each member of the Restricted Party Group will not, without the prior written consent of Chesapeake or as otherwise specifically permitted under paragraph 2.2 hereof, directly or indirectly: (a) own, acquire or solicit the acquisition of (or assist any other Person to own, acquire or solicit the acquisition of) any Oil and Gas Interests, or any option or other right to acquire any Oil and Gas Interests, in any case pertaining to or covering, in whole or in part, the Lands; (b) conduct (or assist any third person to conduct) any Oil and Gas Business on or with respect to the Lands; or (c) acquire any interest or the right to acquire any interest in a Person that owns Oil and Gas Interests included in clause (a) or conducts activities included in (b) that results in the Restricted Party Group and the Related Parties owning or having the right to acquire more than forty percent (40%) of such Person. In addition to the foregoing, during the Protection Period, each member of the Restricted Party Group will not, Exhibit "B" Page 2 of 8 Pages without the prior consent of Chesapeake, directly or indirectly terminate, own, acquire, solicit or otherwise interfere with any of Canaan's Oil and Gas Interests pertaining to or covering in whole in part the Lands or in anyway attempt to do any of the foregoing or assist any third person to do any of the foregoing. 2.1 The limitations in this paragraph 2 will not prohibit any investment by the Restricted Party or the Restricted Party Group in securities which are listed on a public exchange or the National Association of Securities Dealers Automated Quotation System issued by a company, firm, corporation, partnership, trust or other entity involved in or conducting an Oil and Gas Business, provided that the Restricted Party and the Restricted Party Group own no more than fifteen percent (15%) of the outstanding voting securities of such entity. 2.2 The parties hereto recognize that, during the Protection Period, the Restricted Party and/or the Restricted Party Group may desire to acquire one or more packages of Oil and Gas Interests which include Oil and Gas Interests both inside and outside the Lands (each a "Package"). Nothing in this Agreement will prohibit any such acquisition of a Package, and no such acquisition or the resulting ownership of such Oil and Gas Interests will constitute a violation of this paragraph 2, as long as the number of Oil and Gas Interests included in such Package is greater than twenty five (25) and the value of the Oil and Gas Interests lying outside the Lands exceeds seventy-five percent (75%) of the purchase price of the Package. In the event the Restricted Party Group acquires a Package which contains more than twenty five (25) Oil and Gas Interests but does not satisfy the foregoing or which contains less than twenty five (25) Oil and Gas Interests, such acquisition and the resulting ownership of such Oil and Gas Interests will not constitute a violation of this Agreement, if within twenty (20) days after any such acquisition, the Restricted Party: (a) notifies Chesapeake of such acquisition, specifying the Oil and Gas Interests acquired in the Lands (the "Offered Interests") and specifying the portion of the acquisition price for such Package allocated to the Offered Interests; and (b) grants the Chesapeake Companies the right, for a period of twenty (20) days after receipt of such notice, to acquire the Offered Interests from the Restricted Party or the Restricted Party Group at the same acquisition price paid therefor by the Restricted Party or the Restricted Party Group. Notwithstanding the foregoing, in the event any of the Offered Interests are subject to an existing preferential right to purchase ("Third Party Rights"), the Restricted Party will provide Chesapeake with all notices of Third Party Rights as and when provided to the holders thereof and will take such actions as may be prudent to permit the Chesapeake Companies to step into the shoes of the Restricted Party during the period such Third Party Rights are outstanding so that, in the event such Third Party Rights are not exercised in accordance with the terms thereof, the Chesapeake Companies will have the ability to acquire such Offered Interests without the necessity of re-instituting another Third Party Rights offer. For purposes of calculating the number of Oil and Gas Interests in a Package, the following will be considered an individual Oil and Gas Interest under this paragraph: (y) all of the Restricted Group's rights and ownership in a governmental spacing or production Exhibit "B" Page 3 of 8 Pages unit for a producing well; and (z) with respect to non-producing assets, all of the Restricted Group's rights and ownership in the area covered by a single prospect. 2.3 Nothing in this Agreement will prevent or prohibit any member of the Restricted Party Group from being employed by any Person which is not a member of the Restricted Party Group or, so long as the member of the Restricted Party Group does not use Confidential Information or Derivative Information, from assisting any such Person as an advisor, consultant or independent contractor, regardless of whether such person or entity owns, acquires or solicits the acquisition of any Oil and Gas Interests, or any option or other right to acquire any Oil and Gas Interests, pertaining to or covering, in whole or in part, any of the Lands, or conducts any Oil and Gas Business on or with respect to the Lands. 3. Confidentiality. The Restricted Party hereby acknowledges that, during the --------------- term of the Restricted Party's relationship with Canaan, the Restricted Party has developed and had access to Confidential Information and Derivative Information. The Restricted Party hereby agrees as follows with respect to all Confidential Information and Derivative Information: 3.1 Upon execution of this Agreement, the Restricted Party will, and will cause each member of the Restricted Party Group to, immediately return to Canaan all Confidential Information and Derivative Information in the possession of the Restricted Party or any member of the Restricted Party Group. 3.2 For a period of two (2) years after the date hereof, the Restricted Party will, and will cause the members of the Restricted Party Group to, keep all Confidential Information and Derivative Information and the results of any analyses of such data and information strictly confidential and will not, and will cause the members of the Restricted Party Group not to, use any of such data, information or results or disclose any such data, information or results to any Person unless otherwise required by law or regulation and then only after written notice to Canaan of the determination of the need for disclosure. 3.3 In the event that the Restricted Party or any member of the Restricted Party Group becomes legally compelled to disclose any Confidential Information and/or Derivative Information, the Restricted Party will provide Canaan with prompt notice so that Canaan may seek a protective order or other appropriate remedy and/or waive the Restricted Party's compliance with the confidentiality and non-disclosure provisions of this Agreement. In the event that such protective order or other remedy is not obtained, the Restricted Party will furnish only that portion of the Confidential Information and/or Derivative Information which it is advised by counsel is legally required. 4. Separate Covenants. This Agreement will be deemed to consist of a series of ------------------ separate covenants independent from any provision of the Merger Agreement. The Restricted Party expressly agrees that the character, duration and geographical scope of this Agreement are reasonable in light Exhibit "B" Page 4 of 8 Pages of the circumstances as existing on the date of this Agreement. However, should a determination nonetheless be made by a court of competent jurisdiction at a later date that the character, duration or geographical scope of this Agreement is unreasonable in light of the circumstances as then existing or existing at the execution of this Agreement, then it is the intention and the agreement of the Restricted Party, Chesapeake and CHK that this Agreement be construed by the court and given effect in such a manner as to impose only the restrictions on the conduct of the Restricted Party which are reasonable in light of the circumstances as then existing and as are necessary to assure Chesapeake and CHK of the intended benefit of this Agreement and the Merger Agreement. If, in any judicial proceeding, a court refuses to enforce all of the separate covenants included herein because, taken together such covenants are more extensive than necessary to assure Chesapeake and CHK of the intended benefit of this Agreement, it is expressly understood and agreed between the parties that those covenants not to be enforced in such proceeding will, for the purpose of such proceeding, be deemed eliminated from the provisions hereof. 5. Periodic Payments. As additional consideration for the Restricted Party's ----------------- execution, delivery and performance of this Goodwill Protection Agreement, Chesapeake agrees to pay to the Restricted Party the sum of $_____________ payable in three (3) equal payments of $_____________ each. The first payment will be due on the execution of this Agreement, the second payment will be due on the date which is one (1) year after the execution of this Agreement and the third payment will be due on the date which is two (2) years after the execution of this Agreement. 6. Default. The Restricted Party will be responsible for any violation of ------- provisions hereof by any member of the Restricted Party Group. If the Restricted Party fails to perform any obligation contained in this Agreement or fails to cause the Restricted Party Group to perform the terms of this Agreement, Chesapeake or CHK may serve written notice to the Restricted Party specifying the nature of such default and demanding performance. If such default has not been cured within five (5) business days after receipt of such default notice, Chesapeake and/or CHK will be entitled to demand specific performance, suspend performance of any obligation under this Agreement, or exercise all remedies available at law or in equity. Given the nature of the assets to be acquired by Chesapeake under the Merger Agreement, the parties acknowledge and agree that the goodwill purchased by Chesapeake cannot be protected if the provisions of this Agreement are not strictly enforced. Accordingly, the parties acknowledge and agree that, if there is a breach by the Restricted Party of the provisions of this Agreement, money damages alone will not be adequate and the Chesapeake Companies will be entitled to an injunction restraining the Restricted Party or the Restricted Party Group from violating the provisions of this Agreement. The remedies provided by this Agreement are cumulative and will not exclude any other remedy to which a party might be entitled under this Agreement. In the event a party elects to selectively and successively enforce such party's rights under this Agreement, such action will not be deemed a waiver or discharge of any other remedy. 7. Miscellaneous. It is further agreed as follows: ------------- 7.1 Notices. Except as expressly provided herein, any notice, demand or ------- communication required or permitted to be given by any provision of this Agreement will be in writing and will be deemed to have been given and received when delivered Exhibit "B" Page 5 of 8 Pages personally or by telefacsimile to the party designated to receive such notice, or on the date following the day sent by overnight courier, or on the third (3rd) business day after the same is sent by certified mail, postage and charges prepaid, directed to the following addresses or to such other or additional addresses as any party might designate by written notice to the other parties: To any of the Chesapeake Companies: Mr. Henry J.

If any clause or provision of this Agreement is illegal, ------------ invalid or unenforceable under any present or future law, the remainder of this Agreement will not be affected thereby. It is the intention of the parties that if any such provision is held to be illegal, invalid or unenforceable, there will be added in lieu thereof a provision as similar in terms to such provisions as is possible and to be legal, valid and enforceable. 7.3 Entire Agreement. This Agreement, together with the Merger Agreement ---------------- and the other instruments executed in connection therewith, constitute the entire agreement between the parties with respect to the subject matter hereof and there are no agreements, understandings, warranties or representations except as set forth herein and therein. Neither this Agreement nor any of the provisions hereof can be changed, waived, discharged or terminated except by an instrument signed by the party against whom enforcement of the change, waiver, discharge or termination is sought. 7.4 Attorneys' Fees.

Waiver of performance of any obligation or term contained in ------ this Agreement by any party, or waiver by one party of the other's default hereunder will not operate as a waiver of performance of any other obligation or term of this Agreement or a future waiver of the same obligation or a waiver of any future default. 7.6 Assignment. No party hereto may assign all or any portion of his or ---------- its rights or obligations hereunder without the prior written consent of the other parties hereto; provided, however, CHK may assign all or any portion of its rights hereunder to (a) any other entity or person which at any time controls or is under common control with CHK, or (b) any entity or person which acquires all of CHK's Oil and Gas Business with respect to the Lands. 7.7 Governing Law.

McClendon, Chief Executive Officer ("CHK") Exhibit "B" Page 7 of 8 Pages ____________________________________________________ ______________________________________, individually (the "Restricted Party") Exhibit "B" Page 8 of 8 Pages OFFICE SPACE AGREEMENT ---------------------- THIS AGREEMENT (this "Agreement") is made effective the _____ day of __________, 2002, between LJ NATURAL GAS COMPANY, an Oklahoma corporation (the "Option Holder"), and CANAAN ENERGY CORPORATION, an Oklahoma corporation ("Canaan"). W I T N E S S E T H: WHEREAS, Chesapeake Acquisition, Inc., an Oklahoma corporation ("CHK"), Chesapeake Energy Corporation, an Oklahoma corporation, and Canaan entered into that certain Agreement and Plan of Merger dated April 19, 2002 (the "Merger Agreement"); WHEREAS, Canaan entered into a Lease Agreement with LSQ Investors, L.L.C., an Oklahoma limited liability company, dated December 4, 2000, as amended by the First Amendment to Lease Agreement dated effective July 18, 2001, and the Second Amendment to Lease Agreement dated October 8, 2001 (the "Lease"), covering certain office space in downtown Oklahoma City, Oklahoma (the "Office Space"); WHEREAS, Canaan owns office equipment together with nonproprietary information concerning oil and gas properties such as scout cards and other information generally available for purchase or subscription (collectively, the "Equipment") and leases office equipment ("Equipment Leases") located in the Office Space which Equipment and items covered by the Equipment Leases are listed at Schedule "1" attached as a part hereof detailing the items and the book value of each such item (collectively, the "Office Equipment"); and WHEREAS, in connection with the Merger Canaan has determined that the Office Space and Office Equipment may be surplus and as a result Canaan is extending to the Option Holder the right to acquire all or part of the Office Space the Office Equipment. NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 1. Temporary Office Space. For a period of ninety (90) days after the date of ---------------------- this Agreement (the "Use Period") the Option Holder will have the right to occupy that portion of the Office Space being leased by Canaan on April 1, 2002, without paying rent on such Office Space and use the Office Equipment. The foregoing use of the Office Space and Office Equipment is conditioned on: (a) any consents or other actions which Chesapeake determines is necessary or appropriate to permit the use by the Option Holder of the Office Space and the items covered by the Equipment Leases; (b) the payment by the Option Holder of all expenses (other than base rent under the Lease) allocable or chargeable to the Use Period including, without implied limitation, any taxes, utilities, telephone charges, repairs, communication charges, line access charges and other expenses of occupying the Office Space; and (c) the payment of all charges under the Equipment Leases allocable to the Use Period. Notwithstanding anything herein to the contrary, Chesapeake, CHK and Canaan (the "Canaan Parties") will not be required to take any actions which will impose any expense, liability or Exhibit "C" Page 1 of 6 Pages payment obligation on the Canaan Parties in excess of the amounts that were being paid by Canaan under the Lease or the Equipment Leases prior to the date of the Merger Agreement and the Canaan Parties will not be required to amend, renew, extend or expand the Lease or any of the Equipment Leases. 2. Office Space Acquisition. The Option Holder will also have the right to ------------------------ acquire all or part of the Office Space on the following terms: 2.1 Option. During the Use Period the Option Holder will have the right to ------ sublease or acquire all or part of the Office Space by providing written notice to Canaan specifying the portion of the Office Space to be sublet or acquired by the Option Holder. The portion of the Office Space to be subleased or acquired hereunder will be a single contiguous block of space and will not render the remaining Office Space unrentable or unusable at the then current rates in effect in the building where the Office Space is located as reasonably determined by Chesapeake. The terms of the sublease will be on the same terms as the Lease and will be for the remaining term of the Lease with respect to such Office Space except that the Option Holder will be solely responsible for all costs and expenses relating to the separation of the designated space from the remaining Office Space. At the election of Canaan, the Option Holder agrees to enter into a new lease covering the Office Space covered by the Option Holder's notice under this paragraph in order to release the Canaan Parties for any liability under the Lease with respect to that portion of the Office Space. Each of the actions and agreements under this paragraph are expressly subject to any and all consents or waivers by the landlord under the Lease which Canaan and Chesapeake reasonably determine are necessary or appropriate. 2.2 Right of First Refusal. Subject to the Option Holder exercising the ---------------------- Option under paragraph 2.1 for a portion of the Office Space, Canaan grants to the Option Holder a right of first refusal on that portion of the Office Space which the Option Holder does not elect to sublease or acquire under paragraph 2.1 of this Agreement to run for the period commencing on the last day of the Use Period and ending on the date which is two (2) years after the date of this Agreement (the "ROFR Period"). In the event that during the ROFR Period Canaan desires to sublease, convey, transfer or surrender a portion of the Office Space, Canaan will provide written notice (the "Transfer Notice") to the Option Holder which states: (a) the portion of the Office Space to be sublet, transferred, conveyed or surrendered; and (b) the proposed terms of such sublease, conveyance, transfer or surrender. For ten (10) days after the receipt of the Transfer Notice, the Option Holder will have the preemptive option to acquire the portion of the Office Space which is the subject of the Transfer Notice on the terms set forth in the Transfer Notice. In the event of a surrender of the Lease to the landlord, such terms will include a full release of the Canaan Parties from any obligations with respect to the portion of the Office Space covered by the Transfer Notice and the payment to the Option Holder of any amount payable to the Landlord by Canaan. If the Option Holder does not elect to exercise the Option Holder's rights hereunder with respect to all of the portion of Office Space covered by the Transfer Exhibit "C" Page 2 of 6 Pages Notice, Canaan will have the right to sublet, transfer, convey or surrender the Office Space covered by the Transfer Notice on terms no better to the prospective tenant or landlord than the terms set forth in the Transfer Notice. The rights under this paragraph will expire without any further action by any party on the date which is two (2) years after the date of this Agreement. Each of the actions and agreements under this paragraph are expressly subject to any and all consents or waivers by the landlord under the Lease which Canaan and Chesapeake reasonably determine are necessary or appropriate. 3. Equipment. During the period commencing on the date of this Agreement and --------- ending on the date sixty (60) days after the date of this Agreement, the Option Holder will have the one (1) time right to: (a) purchase all or part of the Equipment; and (b) sublease or acquire Canaan's rights under one or more of the Equipment Leases. Such right will be exercised by the Option Holder providing written notice to Canaan specifying the Equipment or Equipment Lease to be acquired, delivering with such notice the cash purchase price for such Equipment and the appropriate consents and assumption documents for the Equipment Leases. The purchase price for the Equipment will be equal to: (y) twenty five percent (25%) of the book value for all of the items of Equipment to be purchased under this paragraph reduced to the nearest multiple of Twenty-Five Thousand Dollars ($25,000.00); plus (z) all costs and expenses associated with the assumption of the acquired Equipment Leases. For purposes of the foregoing computation the book value will be determined as of the later of December 31, 2001, or the date of the purchase of the item of Equipment. In the event the Option Holder elects to acquire one or more Equipment Leases the Option Holder will be responsible for all lease payments and charges under such Equipment Leases and agrees to hold Canaan harmless with respect to such Equipment Leases. Any computer purchased under this paragraph will, subject to the terms of the applicable license, include all software that is validly installed on such computer in accordance with such license and all rights with respect to the applicable software license. The Option Holder agrees to hold Canaan harmless from any and all liability, obligations and losses from breach of such software license. Although the option under this paragraph can be exercised on a piece by piece basis, systems or integrated items of Equipment (such as the phone system) must be purchased in their entirety. 4. Default. In the event that either party fails to perform such party's ------- obligations hereunder (except as excused by the other party's default), the party claiming default will make written demand for performance. If the Option Holder fails to comply with such written demand within five (5) days after receipt thereof, Canaan will have the option of waiving such default, to exercise any other remedy available at law or in equity, or to terminate this Agreement. If Canaan fails to comply with such written demand within five (5) days after receipt thereof, the Option Holder will have the option of waiving such default or to exercise any other remedy available at law or in equity. The remedies provided by this Agreement are cumulative and will not exclude any other remedy to which a party might be entitled under this Agreement. In the event a party elects to selectively and successively enforce such party's rights under this Agreement, such action will not be deemed a waiver or discharge of any other remedy.
