As used herein, the term "Title Defect" shall mean any lien, claim, 2a-3 4 defect, encumbrance, security interest, burden or deficiency such that the Companies (directly or indirectly) do not have Defensible Title (hereinafter defined), as distinguished from technically marketable title, to any item of the Examined Interests; provided, no Permitted Encumbrance (hereinafter defined) shall constitute a Title Defect.

(c) As used herein, the term "Permitted Encumbrances" means (i) matters described without material omission in any of the Exhibits or Schedules attached hereto, (ii) royalties, overriding royalties, net profits interests, production payments and other burdens on production which do not reduce the Companies' Net Revenue Interest in any of the Reserve Report Properties to less than that described in Exhibit D, (iii) liens for taxes, assessments, labor and materials where payment is not due, (iv) 2a-4 5 operating agreements, unit agreements, unitization and pooling designations and declarations, gathering and transportation agreements, processing agreements, gas, oil and liquids purchase, sale and exchange agreements, and other similar agreements which are not required by the terms of this Agreement to be disclosed on any Schedule hereto, provided (A) they contain terms and conditions customary in the oil and gas industry, (B) they do not adversely affect or burden the ownership of the Sycamore System or the Reserve Report Properties (C) all amounts due and payable by the Companies thereunder have been paid in full, and (D) the Companies are not in material default thereunder, (v) regulatory authority of governmental agencies not presently or previously violated, easements, surface leases and rights, plat restrictions and similar encumbrances, provided that they do not materially detract from the value, materially increase the cost of operation of any item of the Examined Interests or otherwise adversely affect the operation thereof, and (vi) liens, charges, encumbrances and irregularities in the chain of title which, because of remoteness in or passage of time, statutory cure periods, marketable title acts or other similar reasons, have not affected or interrupted, and are not reasonably expected to affect or interrupt, the claimed ownership of the Companies or their predecessors in title or the receipt of production revenues from the Properties affected thereby. 3.3 Title Examination; Notice of Defects. (a) Promptly after execution of this Agreement, Buyer shall, at Buyer's sole cost and expense, commence and pursue such examination of title to the Examined Interests as Buyer deems necessary or proper. Buyer will conclude its title review and give notice to Sellers of any asserted Title Defects affecting the Examined Interests not later than fourteen (14) days prior to the date scheduled for the Closing in Section 13.1 hereof (the "Title Notice Date"). Each such notice shall include a brief description of each Title Defect of which notice is being given, the action required to cure such Title Defect and the proposed adjustment to the Base Price by reason of the existence of such Title Defect. Buyer shall be deemed to have waived any Title Defects existing with respect to the Examined Interests except to the extent such Title Defects are set out in a notice given on or prior to the Title Notice Date. (b) Sellers shall have a period of eleven (11) days after the Title Notice Date to cure or cause the Companies to cure all or any portion of the Title Defects described in any notice(s) of Title Defects affecting Examined Interests properly given by Buyer prior to such date. All costs and expenses incurred by the Companies in curing Title Defects so noticed by Buyer shall result in a downward adjustment of the Base Price at the Closing. In the event Sellers are unable or unwilling to cure or cause the Companies to cure any of the asserted Title Defects prior to the expiration 2a-5 6 of each cure period, the parties shall proceed in accordance with Section 3.4. 3.4 Adjustments. (a) If any uncured Title Defect is based on Buyer's notice that the Companies own a Net Revenue Interest less than that shown on Exhibit D with respect to a particular Reserve Report Property, then provided the working interest owned by the Companies in such Property remains proportionate to that set out in Exhibit D, the Agreed Value of such Property shall be reduced in the same proportion that the actual Net Revenue Interest bears to the Net Revenue Interest shown therefor on Exhibit D and the amount of such reduction shall constitute the approved adjustment amount with respect to such Title Defect. (b) If any uncured Title Defect involves a claim against or uncertainty with respect to the Companies' title to a particular item of the Examined Interests, the parties shall attempt to negotiate a mutually acceptable reduction in the Agreed Value of such Property by reason of such defect. In the event the parties agree on an appropriate reduction in the Agreed Value, such amount shall constitute the principal amount of Buyer's approved claim with respect to such Title Defect. If the parties are unable to agree on an appropriate reduction and Buyer elects not to waive the Title Defect, then Sellers shall have the option of (i) proceeding to Closing but reducing the Base Price by the Agreed Value of such Property if acceptable to Buyer, or (ii) proceeding to Closing but prior thereto causing the Companies to assign the affected Property to a third party (which may be owned by Sellers) and reducing the Base Price by the Agreed Value of such Property, or (iii) proceeding to Closing but directing the Buyer to separately deposit under an escrow agreement to be established pursuant to Section 3.5 hereof that number of Exchange Shares having a Closing Value equal to not less than the Agreed Value of the affected Property and referring to arbitration (to be conducted in accordance with the procedures set out in Section 3.6 hereof) the dispute concerning the proper amount, if any, of the reduction of the Base Price (not to exceed the Agreed Value) by reason of such Title Defect. Option (i) and (ii) of this subparagraph 3.4(b) shall not be applicable with respect to unresolved Title Defects affecting the Sycamore System. In the event the aggregate adjustment for Title Defects exceeds the sum of $1,000,000, either Sellers or Buyer may terminate this Agreement prior to the Closing by written notice to the other without further liability to Buyer or Sellers other than return of the Deposit. (c) If, prior to the Title Notice Date, either Sellers or Buyer determine that the Net Revenue Interest owned by the Companies in any Reserve Report Property is greater than that set forth on Exhibit D, then provided the Working Interest owned by the Companies in such Property remains proportionate to that set out 2a-6 7 in Exhibit D, the Agreed Value of such Property shall be increased in the same proportion that the actual Net Revenue Interest bears to the Net Revenue Interest shown therefor in Exhibit D and such increase shall constitute an upward adjustment to the Base Price. The party discovering any such error promptly shall notify the other so that the appropriate adjustment may be made. 3.5 Title Escrow. In the event the Base Price adjustment by reason of any asserted Title Defect is not determined at or prior to the Closing pursuant to the provisions of Section 3.4 hereof and Sellers elect to refer the determination of the appropriate adjustment, if any, to arbitration, then at the Closing Sellers, Buyer and the Deposit Holder shall execute an escrow agreement in the form attached hereto as Exhibit F (the "Escrow Agreement"), and Buyer will deposit with the Deposit Holder (defined under the Escrow Agreement as the "Escrow Agent") that number of Exchange Shares having a Closing Value equal to not less than the Agreed Values of the interests in the Properties affected by said asserted Title Defects (such Exchange Shares being referred to herein as the "Title Escrow"), with said Title Escrow to be held, administered and distributed pursuant to the terms of the Escrow Agreement. 3.6 Arbitration. In the event any Title Defect claim timely and properly noticed by Buyer is referred by Sellers to arbitration, a binding arbitration proceeding promptly shall be conducted in Oklahoma City, Oklahoma, in accordance with the Commercial Arbitration Rules of the American Arbitration Association ("AAA"). The arbitration proceeding shall be conducted by a single arbitrator agreed to by the parties, or if they are unable to agree, selected by the AAA. The arbitrator shall be a licensed attorney experienced in oil and gas title examination or systems such as the Sycamore System, as appropriate. The decision of the arbitrator with respect to the amount, if any, of the allowed claim for each Title Defect referred to arbitration shall be conclusive and binding upon the parties; provided, however, that in no event shall the allowed claim exceed the Agreed Value of the Property subject to the claimed Title Defect. The general expenses of arbitration, including the fees of the AAA if necessitated by reason of the failure of the parties to agree upon an arbitrator, shall be borne equally by Sellers and Buyers; however, each party shall bear and pay the fees and expenses of its own witnesses, legal counsel and of the collection and presentation of its evidence. The decision of the arbitrator shall be effected by joint written instructions from the parties to the Escrow Agent, subject to the threshold requirements of Section 3.5 hereof.

In the event there is insufficient cash in the Companies to make the authorized distribution prior to the Closing Date, the Base Price shall be adjusted upward at the Closing by the amount authorized but not distributed due to such shortfall. 8.9 Conduct of Buyer's Business During the Valuation Period. During the period from the beginning of the Valuation Period until the Closing, Buyer shall conduct its business in accordance with historical practices, not issue new stock or rights with respect to stock, distribute or dispose of any material assets, declare any extraordinary dividends, or take any other action that would cause the value of the Exchange Shares to be less than such value would have been if Buyer had not taken such action. 8.10 Severance Payments.

Subject to Sellers' indemnification obligations under this Agreement with respect to representations and warranties concerning environmental matters, all liabilities attributable to conditions existing and operations conducted on the Properties (other than Properties assigned to a third party prior to the Closing pursuant to Section 9.5 hereof) under Applicable Environmental Laws and under all future environmental laws shall be liabilities of the Companies or of Sycamore, as applicable, and Buyer shall indemnify, defend, and hold harmless Sellers from and against all loss, cost, liability or expense attributable thereto or resulting therefrom.

Each of the representations and warranties of Sellers set forth in this Agreement shall be true and correct in all material respects as of the date of this Agreement (except to the extent such representations and warranties speak to an earlier date), and as of the Closing Date as though made on such date, except where the failure to be so true and correct (without giving effect to the individual materiality, qualification and thresholds otherwise contained in Sections 4 and 5 hereof) would not reasonably be expected to have a Material Adverse Effect on Buyer or as otherwise contemplated by this Agreement and Buyer shall have received a certificate signed by the Chief Executive Officer of PSEC and PSPC to such effect. 10.2 Performance of This Agreement. Sellers shall have duly performed or complied in all material respects with all of the obligations to be performed or complied with by Sellers under the terms of this Agreement on or prior to the Closing Date and Buyer shall have received a certificate signed by the Chief Executive Officer of PSEC and PSPC to such effect. 10.3 Resignations. Buyer shall have received the written resignations of each member of the Board of Directors and each officer of the Companies that is a Seller or an affiliate of a Seller. 10.4 Opinion of Counsel. Buyer shall have received an opinion of McAfee & Taft A Professional Corporation, dated the Closing Date, substantially in the form attached hereto as Exhibit G. 2a-28 29 10.5 Closing of Related Agreements. The contemporaneous, separate but related Sale and Purchase Agreements between Sellers and their affiliates, as Sellers, and Buyer shall close simultaneously with the Closing under this Agreement. ARTICLE 11 CONDITIONS TO OBLIGATIONS OF SELLERS The obligations of Sellers to consummate the transactions provided for in this Agreement shall be subject to the satisfaction of each of the following conditions on or before the Closing Date, subject to the right of Sellers to waive any one or more of such conditions: 11.1 Representations and Warranties of Buyer. The representations and warranties of Buyer contained in this Agreement shall be true and correct in all material respects at and as of the Closing Date, and Sellers shall have received a certificate signed by a Vice President of Buyer to such effect. 11.2 Performance of This Agreement. Buyer shall have duly performed or complied in all material respects with all of the obligations to be performed or complied with by Buyer under the terms of this Agreement on or prior to the Closing Date, and Sellers shall have received a certificate signed by a Vice President of Buyer to such effect. 11.3 Shelf Registration Agreement. ONEOK shall have executed and delivered to the Sellers a Shelf Registration Agreement substantially in the form attached hereto as Exhibit I (the "Shelf Registration Agreement"). 11.4 Opinion of Counsel. Sellers shall have received an opinion of Arrington, Kihle, Gaberino & Dunn, dated as of the Closing Date, substantially in the form attached hereto as Exhibit H. 11.5 Closing of Related Agreements. The contemporaneous, separate but related Sale and Purchase Agreements between Sellers and their affiliates, as Sellers, and Buyer shall close simultaneously with the Closing under this Agreement. ARTICLE 12 TERMINATION 12.1. Noncompliance by Sellers. Buyer may terminate this Agreement by written notice to Sellers if the conditions to Buyer's obligations under this Agreement, as set forth in Article 10 hereof, shall not have been complied with or performed in all material respects (and Sellers shall not be prepared to comply with or 2a-29 30 perform the same) by the date on which the Closing is to occur (as set forth in Section 13.1), and such non-compliance or non-performance shall not have been waived in writing by Buyer. Under such circumstances, Buyer shall be entitled to a return of the Deposit, which shall be Buyer's sole remedy hereunder unless such termination is a result of Sellers' failure or refusal to close the transaction contemplated hereby under circumstances in which all conditions precedent to Sellers' obligations as set forth in Article 11 have been performed or satisfied in all material respects, in which event Buyer shall be entitled to pursue any remedies existing at law or in equity. 12.2. Noncompliance by Buyer. Sellers may terminate this Agreement by written notice to Buyer if the conditions to Sellers' obligations under this Agreement, as set forth in Article 11 hereof, shall not have been complied with or performed in all material respects (and Buyer shall not be prepared to comply with or perform the same) by the date on which the Closing is to occur (as set forth in Section 13.1), and such non-compliance or non-performance shall not have been waived in writing by Sellers. In such event, Sellers shall retain the Deposit as liquidated damages for Buyer's failure to purchase the Shares at the time specified herein. The parties hereto agree that time is of the essence for the consummation of the transactions contemplated hereby, that the amount of damages caused by Buyer's breach would be very difficult to calculate exactly, and that the provision for liquidated damages contained in this Section 12.2 shall not be construed as a penalty provision. Such right to liquidated damages shall be Sellers' sole remedy hereunder. 12.3. Cooperation by Buyer. In the event of termination of this Agreement by mutual agreement of the parties, Sellers shall be free to sell the Shares to any third party without any limitation under or by reason of this Agreement. Buyer shall cooperate with Sellers in effectuating any such sale by promptly executing any instrument reasonably requested by Sellers evidencing the termination of this Agreement or Buyer's right to acquire the Shares. 12.4. Arbitration. In the event this Agreement is terminated by Buyer pursuant to Section 12.1 hereof or by Sellers pursuant to Section 12.2 hereof and a dispute exists between the parties with respect to entitlement to the Deposit, such dispute shall be resolved by binding arbitration conducted in accordance with the Commercial Arbitration Rules of the AAA. The arbitration proceedings shall be conducted in Oklahoma City, Oklahoma, by a single arbitrator agreed to by the parties, or if they are unable to agree, selected by the AAA. The arbitrator shall be a licensed attorney experienced in transactions involving the sale and purchase of the stock or assets of oil and gas companies. The arbitrator shall be instructed to make a determination that either Buyer is entitled to return of the entire Deposit or Sellers are entitled to retain the entire Deposit. The decision of the arbitrator shall be 2a-30 31 conclusive and binding on the parties. The general expenses of arbitration, including the fees of the AAA if necessitated by reason of the failure of the parties to agree upon an arbitrator, shall be borne equally by Sellers and Buyer; however, each party shall bear and pay the fees and expenses of its own witnesses, legal counsel and of the collection and presentation of its evidence. ARTICLE 13 CLOSING; POST-CLOSING 13.1 Date and Place. The Closing shall be held at 10:00 o'clock a.m. on February 27, 1997 (the date on which the Closing actually occurs is referred to herein as the "Closing Date"). The Closing shall take place in the offices of PSEC, 100 N. Broadway, Suite 3200, Oklahoma City, Oklahoma. 13.2 Satisfaction of Conditions. Not later than two (2) business days prior to the Closing Date, each party shall provide the other party such evidence of satisfaction of conditions under Articles 10 and 11 hereof as the other party shall have reasonably and timely requested. 13.3 Transfer of the Shares. At the Closing, Sellers shall deliver to Buyer certificates registered in the name of Sellers, endorsed in blank, representing the Shares, free and clear of all liens, encumbrances, security interests and adverse claims. 13.4 Determination of Purchase Price. On the day that is two (2) business days prior to the Closing Date, Sellers shall furnish to Buyer (i) a summary of the Base Price adjustments to be effected at the Closing pursuant to Sections 3.3, 3.4, 8.5, 8.6, 8.8 and 9.5 hereof, and (ii) based upon the information at (i), a calculation of the Purchase Price. Buyer and Sellers shall work together diligently and in good faith to agree upon the amount of the Purchase Price prior to the Closing, and if they do so agree, the agreed amount shall be conclusively established as the Purchase Price. If they cannot agree, the Closing shall occur as scheduled based on Sellers' reasonable, good faith estimate of the Purchase Price ("Sellers' Estimate") and certificates representing the number of Exchange Shares so determined shall be issued to Sellers; however, all of such certificates shall be deposited in escrow with the Escrow Agent pending a determination of the final Purchase Price. In such event the final Purchase Price shall be determined either (i) by subsequent agreement of the parties, or (ii) by binding arbitration pursuant to an arbitration proceeding initiated and conducted substantially in accordance with the procedures set out in Section 12.4 hereof. In the event arbitration is necessary to determine the Purchase Price, prior to initiating the arbitration, each party shall furnish to the other a statement of such party's calculation of the Purchase Price. All fees and expenses of the arbitration, including attorneys' fees, expert witness fees and all other out-of-pocket expenses of both parties, 2a-31 32 shall be paid by the party whose calculation of the Purchase Price bears the greatest difference from the Purchase Price determined by the arbitrator. The award of the arbitrator shall not be subject to appeal or judicial review of any nature and shall be promptly furnished to the Escrow Agent who shall make distribution of the Exchange Shares in a manner consistent with such award or, if new certificates are required in order to effect the award of the arbitrator, shall deliver the escrowed certificates upon receipt from Buyer of new certificates representing the number of shares corresponding to the Purchase Price determined by such award. In the event new certificates are required and Buyer does not furnish such certificates within ten (10) days after receipt by Escrow Agent of the award, Escrow Agent shall deliver all originally deposited certificates to Sellers. 13.5 Transfer of the Exchange Shares. (a) At the Closing, Buyer shall deliver to Sellers (or to the Escrow Agent if the Purchase Price has not been agreed upon) stock certificates evidencing Exchange Shares having an aggregate Closing Value (less the value of any fractional share which shall be paid in cash) equal to the Purchase Price (or Sellers' Estimate if the Purchase Price has not been agreed upon), together with cash for any fractional shares. If Sellers have referred to arbitration the resolution of a Title Defect pursuant to Section 3.5, the number of Exchange Shares representing the Title Escrow which are delivered to the Escrow Agent under the Title Escrow Agreement shall be deducted from the number of Exchange Shares delivered to Sellers or the Escrow Agent pursuant to the preceding sentences of this Section 13.5. The number of Exchange Shares issued in the name of each Seller shall be determined by multiplying the aggregate number of Exchange Shares to be issued by the percentage set opposite the name of such Seller in Exhibit A. Fractional shares shall not be issued, in which event the number of shares to be issued to a Seller shall be rounded down to the nearest whole share and the cash for any fractional shares resulting from the Purchase Price shall be distributed to Sellers in proportion to the number of shares received. (b) Each of the Sellers represents and warrants to Buyer that the Exchange Shares it will receive under this Agreement are not being acquired with a view to, or in connection with, a distribution of such Exchange Shares in violation of the Securities Act of 1933, as amended (the "Securities Act"). Sellers understand that (i) the Exchange Shares may not be sold or transferred for value except pursuant to an effective registration statement under the Securities Act or an exemption or exception from the registration requirements under the Securities Act, (ii) a stop transfer instruction will be issued with respect to the Exchange Shares, and (iii) the following legend will be placed on the certificates representing the Exchange Shares: 2a-32 33 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). THE SECURITIES MAY NOT BE SOLD OR TRANSFERRED FOR VALUE EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION UNDER THE ACT, OR AN OPINION OF COUNSEL, WHICH OPINION SHALL BE REASONABLY SATISFACTORY TO THE ISSUER, THAT SUCH REGISTRATION IS NOT REQUIRED.

Each party's liability resulting from any breach of its warranties, representations, or other obligations set forth herein to another party shall be limited, in the aggregate, to the excess of any loss resulting therefrom over $50,000 and Seller's liability shall be limited to the Purchase Price. 14.11 Further Assurances.

W I T N E S S E T H: THAT WHEREAS, this Agreement is being executed and delivered contemporaneously with the execution and delivery of that certain Stock Purchase Agreement of even date herewith between Sellers and Buyer (the "Stock Purchase Agreement"), pursuant to which Sellers have agreed to sell and Buyer has agreed to purchase all of the outstanding shares of the capital stock of PSEC, Inc. and PSPC, Ltd.; and WHEREAS, Section 2.4 of the Stock Purchase Agreement provides for the contemporaneous execution and delivery of a deposit agreement substantially in the form of this Agreement; and WHEREAS, Escrow Agent has agreed to execute this Agreement and to hold the amount deposited hereunder in escrow subject to the terms and conditions hereinafter set forth. NOW, THEREFORE, in consideration of the premises and of the mutual covenants and agreements contained herein, and of other good and valuable consideration, the parties to this Agreement hereby agree as follows: 1. Deposit. Simultaneously with the execution of this Agreement, Buyer is delivering to Escrow Agent, by wire transfer of immediately available funds in accordance with instructions received from Escrow Agent, the sum of $1,000,000 (the "Deposit"), which shall be held, administered and distributed by the Escrow Agent as hereinafter provided. 2. Nature of Deposit. Escrow Agent shall hold the Deposit, and all instruments and certificates received by Escrow Agent as a result of investing the Deposit, and all interest and other earnings thereon, in escrow for the benefit of Sellers and Buyer, and the same shall never become part of the general assets of Escrow Agent but shall always be specifically identified as part of the escrow created hereunder. The obligation of Escrow Agent to deliver the Deposit, and all interest and earnings thereon, in accordance with the terms of this Agreement shall never be considered as a general obligation or indebtedness of Escrow Agent, but rather shall be an obligation to return money, certificates, interest and other property held in escrow. 3. Investments. The Deposit shall be invested by Escrow Agent in U.S. government obligations, money market obliga- 2a-44 45 tions, other short-term cash equivalents or fully-insured bank time deposits (which may be issued by Escrow Agent or its affiliates), as Escrow Agent may deem appropriate. All time deposits issued by Escrow Agent or its affiliates shall be registered in the name of Ray H. Potts and Robert L. Stephenson, as Co-trustees; however, for income tax purposes all income earned on the Deposit shall be allocated to and borne by the party or parties receiving such income. Escrow Agent shall reinvest from time to time all income received by it from investment of the Deposit and all such income shall become a part of the Deposit when and as received. 4. Fees and Expenses. For its services hereunder, Escrow Agent shall be entitled to a fee of $750.00 for the period ending March 31, 1997, and an annual fee of $600.00 for each 12-month period after such time that any amounts remain in escrow hereunder (to be reduced prorata for any fractional portion of a year), plus its actual out-of-pocket expenses. All such fees and expenses shall be paid through a charge against the Deposit. 5. Distributions; Termination. The Escrow Agent shall make distribution of the Deposit (i) as directed by written notice to Escrow Agent executed by Sellers and Buyer, or (ii) to either Sellers or Buyer as determined by a written arbitration award certified to Escrow Agent by either Sellers or Buyer as the award issued as the result of arbitration proceedings between Sellers and Buyer concerning entitlement to the Deposit, whichever of (i) or (ii) above first is received by Escrow Agent. This Agreement and the escrow arrangement created hereunder shall terminate at such time as the entire Deposit has been distributed in accordance with the provisions of this Section 5. 6. Agents for Sellers; Authority; Indemnification. By execution of this Agreement, Sellers hereby designate Ray H. Potts and Robert L. Stephenson as their agents for purposes of giving and receiving notices, instructions and other communications to and from the Escrow Agent pursuant to the terms of the Agreement. Sellers do hereby ratify and confirm each such notice, instruction or other communication hereafter given by the said Ray H. Potts or Robert L. Stephenson, and do hereby agree to hold the Escrow Agent harmless with respect to, and waive any claim that may arise by reason of the Escrow Agent treating as valid or complying with the terms of, any such notice, instruction or other communication. All distributions of the Deposit made to Sellers shall be made to a joint account in the name of Ray H. Potts and Robert L. Stephenson, Co- trustees, to be opened and maintained with Escrow Agent's banking department specifically for the purpose of receiving distributions from the Deposit pursuant to the terms of this Agreement. Escrow Agent is specifically authorized by all parties Seller to make all distributions to Sellers pursuant to this Agreement to said joint account, and upon making any such distribution shall be relieved of all liability or responsibility with -2- 2a-45 46 respect to the allocation or further distribution thereof among Sellers. 7. Inspection; Reports. All money or other property held as a part of the Deposit shall at all times be clearly identified as being held by Escrow Agent under and pursuant to the terms of this Agreement. Any party hereto may inspect the Deposit at any time during Escrow Agent's normal business hours. Escrow Agent shall furnish to Sellers and Buyer, within five (5) business days after receipt of a written request therefor, a report which describes all investments made by Escrow Agent with respect to the Deposit and the balance thereof as of the date of such report. A final report shall be furnished by Escrow Agent within ten (10) days after final distribution of the Deposit. 8. Escrow Agent. Escrow Agent hereby accepts its appointment and agrees to act as Escrow Agent on the terms and subject to the conditions set out in this Agreement. In taking any action hereunder, Escrow Agent shall be protected in relying upon any notice, communication or other document believed by it to be genuine and upon any evidence deemed by it to be sufficient, and in no event shall Escrow Agent be liable for any act performed or omitted to be performed by it hereunder in the absence of gross negligence or willful misconduct. The Escrow Agent may consult with counsel of its choosing in connection with its duties hereunder and shall be fully protected with respect to any act taken, suffered or permitted by it in good faith in accordance with the advice of such counsel. Escrow Agent shall be entitled to recover, as an expense pursuant to Section 4 hereof, the reasonable fees and expenses of such counsel. 9. Litigation Involving Escrow Agent. In the event Escrow Agent becomes involved in litigation by reason of the performance of its duties as Escrow Agent hereunder, it is hereby authorized to deposit with the clerk of the court in which the litigation is pending any and all funds, securities or other property held by it pursuant hereto and thereupon shall stand fully relieved and discharged of any further duties hereunder. Also, in the event Escrow Agent is threatened with litigation by reason hereof, or if a successor Escrow Agent is not agreed upon by the parties as provided in Section 10 hereof, it is hereby authorized to interplead all interested parties in any court of competent jurisdiction and deposit with the clerk of such court any funds, securities or other property held by it pursuant hereto and thereupon shall stand fully relieved and discharged of any further duties hereunder. 10. Resignation. Escrow Agent may, in its sole discretion, resign and terminate its position as escrow agent hereunder upon thirty (30) days prior written notice to Buyer and Sellers. Such resignation shall, when effective, terminate all obligations and duties of Escrow Agent hereunder, except as -3- 2a-46 47 hereinafter set forth. On the effective date of such resignation, Escrow Agent shall deliver this Escrow Agreement together with any and all related instruments and documents, and together with the Deposit, to any successor Escrow Agent agreed to by the parties. If the parties are unable to agree, Escrow Agent may proceed under Section 9 hereof. 11. Notices.

This opinion is being furnished to you pursuant to Section 11.4 of the Agreement. Capitalized terms used but not defined herein have the meanings ascribed to such terms in the Agreement.

The Exchange Shares issued to Sellers at the Closing have been duly authorized and validly issued, are fully paid and non-assessable. The Exchange Shares represent voting stock of ONEOK entitling the holders of such stock to vote on all significant matters as to which stockholders of a corporation normally are entitled to vote, including, without limitation, the election of directors, and to our knowledge no actions have been taken by ONEOK to render the voting power of the ONEOK Stock illusory or insignificant as a class.
