Based upon the representation and agreements being made by it herein, such shares will be issued under this Agreement, and on conversions under the Note, pursuant to an exemption from such registration provided by Section 4(2) of the Securities Act and applicable state securities law qualification exemptions. The Seller represents that it is, and shall, acquire such shares for its own account, for investment purposes only, and not with a view to resale or other distribution thereof, nor with the intention of selling, transferring, or otherwise disposing of PURCHASE AND SALE AGREEMENT - PAGE 12 13 all or any part of such securities for any particular event or circumstance, except selling, transferring, or disposing of them upon full compliance with all applicable provisions of the Securities Act, the Securities and Exchange Act of 1934 as amended, the Rules and Regulations promulgated by the United States Securities and Exchange Commission thereunder, and any applicable state securities laws.

(b) The Seller agrees that each certificate representing any shares of QSR acquired by Seller under this Agreement, and under the Note, will bear on its face a legend in substantially the following form: These securities have not been registered under the Securities Act of 1933 or qualified under any state securities laws. They may not be sold or transferred in the absence of an effective registration statement under that Act or qualification under applicable state securities laws without an opinion of counsel satisfactory to the Company that such registration and qualification are not required. (c) Upon the request of Purchaser, at Closing, a Subscription Agreement shall be executed in counterpart copy by QSR and David Robertson, being the party receiving the QSR Shares.

All expenses relating to such registration allocable to the QSR Shares issued pursuant to this Agreement will be borne by Purchaser. (e) Certain shares of QSR stock are issued under the following agreements, as consideration under such agreements, and as consideration for the extension of the closing under such agreements: (i) Purchase and Sale Agreement dated February 5, 1997, by and between D & R Petroleum, Inc., Black Gold Production Services, Inc., and David R. Robertson, as Seller, and Corrida Resources, Inc., as Buyer, covering various oil and gas rights located in the States of Louisiana, Mississippi, and Texas; and (ii) Purchase and Sale Agreement dated February 5, 1997, by and between Robertson's Oil & Gas, Inc., Pelican Oil Field Services, Inc., and Allen K. Robertson, as Seller, and Corrida Resources, Inc., as Buyer, covering various oil and gas rights located in the States of Louisiana, Mississippi, and Texas. Such agreements are hereinafter referred to as the "Prior Agreements." Such shares of QSR received by the seller's under such Prior Agreements, when sold in compliance with all other restrictions contained in such agreements, may be sold through the public market only on the basis of 10,000 shares in the aggregate being sold within every ninety-day period. Any sales through the public market of any such shares of QSR which exceed 10,000 shares within a ninety day period shall be deemed void. PURCHASE AND SALE AGREEMENT - PAGE 13 14 Simultaneous with the execution of this Agreement, Purchaser is entering a purchase and sale agreement with D & R Petroleum, Inc., and David Robertson, by which document Purchaser is to acquire the rights and interests of such sellers in the Leases, Wells, Equipment and Contracts. Certain shares of stock of QSR will be issued pursuant to the terms of such agreement. Such agreement shall hereinafter be referred to as the "Simultaneous Agreement." The QSR shares to be issued under this Agreement and under the Simultaneous Agreement shall be subject to the same restrictions, above described, governing the shares to be issued under the Prior Agreements, being that, when sold in compliance of all other restrictions contained in such agreements, such shares may be sold through the public market only on the basis of 10,000 shares [inclusive of all shares issued under the Prior Agreements, the Simultaneous Agreement, and this Agreement] in the aggregate being sold within every ninety-day period. Any sales through the public market of any such shares of QSR which exceed 10,000 shares within a ninety day period shall be deemed void. QSR shall have full right and authority to refuse any requested transfer of the certificates of such shares, to the extent the transfers exceed 10,000 shares within a particular ninety day period. The first ninety day period will commence upon the first day that any of said shares become free trading in the public market. 18. Confidentiality. Prior to Closing, the Seller shall be furnishing to Purchaser various information relating to Seller and the Property, and Seller's business activities, assets, finances, costs, revenues, rights, obligations, liabilities, and strategies. In consideration of the Seller furnishing this information to Purchaser, Purchaser agrees that prior to Closing (a) that such information is confidential and/or proprietary to Seller, and such information shall be entitled to and shall receive treatment as such by Purchaser; (b) Purchaser shall use its best efforts, and will advise all of its employees, representatives, agents, and advisors who have access to such information, to use their best efforts to hold in confidence, not to disclose to others, and not to use (except in respect of the transaction contemplated by this Agreement) any such information; and (c) if Closing does not occur, all such information, unless otherwise specified in writing, shall remain the property of Seller, and shall be returned to Seller together with any copies made thereof. Prior to Closing, Purchaser shall provide such information only to its employees, representatives, agents, and advisors who have need to know such information in connection with this Agreement. 19. Overriding Royalty Reservation. Seller reserves and excepts from the purchase and sale contemplated by this Agreement, as an overriding royalty interest, certain of Seller's revenue share in and to the Leases. Purchaser shall be entitled to an NRI interest in and to such Leases which is seventy percent (70%) times the leasehold interest in and to each such Leases acquired by Purchaser from Seller under this Agreement. Any revenue share in and to each such Leases owned by Seller in excess of the revenue share to which Purchaser is entitled under this Agreement is reserved by Seller as an overriding royalty interest. 20. Reversionary Interest. Upon the occurrence of "payout," as such term is hereinafter defined, there shall revert and revest in Seller an undivided one-half (50%) of all of the right, title and interest conveyed to Purchaser by Seller under and pursuant to the terms of this Agreement. The term "payout" as used herein shall mean that point in time when the proceeds received by Purchaser for the revenue share acquired by Purchaser under and pursuant to this Agreement of all of the oil and gas produced, saved and sold from the Wells, and from wells which may be hereafter drilled on the Leases, or on lands pooled with the Leases, equals the sum of the following: (i) the sum of One Hundred Eighty-one Thousand Two Hundred Fifty Dollars ($181,250), and (ii) all of the costs and expenses incurred by Purchaser during the payout period for the drilling, completing, recompleting, equipping, reworking, or plugging and abandoning, of any wells located on the Leases or on lands pooled therewith, including any wells used for salt water disposal and wells used for injection and pressure maintenance, and (iii) all of the costs and expenses incurred by Purchaser during the payout period for operations conducted on the Wells, or on any other wells located on the Leases or on lands pooled therewith, and (iv) all ad valorem, property, production, severance, excise and similar taxes and assessments based on or measured by Purchaser's ownership of the Property, or Purchaser's share of Production from the Property or receipt of proceeds therefrom, which have become due and payable during the payout period, including any portion which may be prorated to the payout period, and (v) all losses, damages and expenses sustained by Purchaser arising out of, or resulting from, PURCHASE AND SALE AGREEMENT - PAGE 14 15 the ownership of the rights and interests to have been conveyed to Purchaser under this Agreement, to the extend same are not paid by Seller under the indemnitee, or other provisions of this Agreement. The interests herein reserved shall automatically revert and revest into Seller upon the occurrence of payout. Notwithstanding, to reflect the occurrence of payout of record in the Parish in which the leased premises are located, upon the occurrence of payout Purchaser agrees to execute and deliver to Seller an assignment in recordable form which shall reassign and reconvey to Seller the interests having reverted to Seller under the terms of this Agreement. The interests which shall have reverted to Seller under and pursuant to the terms of this Agreement shall be governed by, and subject to, the terms and provisions of the current operating agreement covering the Leases and Wells. 21. Preferential Right to Purchase. Should Seller hereafter desire to sell all or any part of the reversionary interest herein reserved by Seller, whether before or after the time of reversion, Seller shall promptly give written notice to the Purchaser, with full information on its proposed disposition, which shall include the name and address of the prospective purchaser (who must be ready, willing and able to purchase), the purchase price, a legal description sufficient to identify the interest and property to be sold, and all other terms of the offer. Purchaser shall then have an optional prior right, for a period of thirty (30) days after the notice is delivered, to purchase for the stated consideration on the same terms and conditions the interest which the Seller proposes to sell. 22. Area of Non-Competition. Seller agrees not to compete with Purchaser in an area which shall be the leasehold premises of the Leases. In this regard, Seller agrees that Seller, its employees, agents, servants, or companies controlled by Seller, in common control with Seller, or with whom Seller is affiliated, shall not acquire, for so long as a Lease is held in force and effect by its terms, and for a period of three years thereafter, any oil and gas leases, any mineral interest, royalty interest, overriding royalty interest, or any farmout agreement, or other agreement permitting the right to explore for and produce oil and/or gas, which cover any lands within the restricted area. 23. Area of Mutual Interest. The Parties agree that an area which shall extend outward from the boundaries of each of the Leases for a distance of 5,280 feet shall be an area of mutual interest between the Parties for a period of seven years from the date of Closing under this Agreement. If any Party should hereafter during the period of mutual interest acquire any oil and gas leases, any mineral interest, royalty interest, overriding royalty interest, or any farmout agreement, or other agreement permitting the right to explore for and produce oil and/or gas, covering any lands within the area of mutual interest, then the acquiring Party shall notify the non-acquiring Party, and shall deliver to the non-acquiring Party (i) copies of the documents by which the acquiring Party acquired the particular interest, and copies of all title information in the possession or control of the acquiring party relating to the particular interest, and (ii) copies of checks or other documents evidencing the actual costs to third parties incurred by the acquiring Party in its acquisition of the particular interest. For a period of thirty days following the receipt of such information the non-acquiring Party shall have the option to acquire an undivided fifty percent (50%) of the particular interest for which the non-acquiring Party has received notice. If the non-acquiring Party shall timely give such notice, closing shall thereafter occur within ten days in the office of the acquiring Party, or at such other location to which the Parties may mutually agreed. At closing the acquiring Party shall deliver to the non-acquiring Party an assignment, deed or other appropriate conveyance, properly executed in recordable form, conveying an undivided one-half of the particular interest, and the non-acquiring Party shall deliver to the acquiring Party one-half of the actual costs to third parties incurred by the acquiring Party in the acquisition of the particular interest. The failure of the non-acquiring Party to respond within the thirty day period shall be deemed an election by the non-acquiring Party not to acquire any share of the particular interest having been acquired by the acquiring Party. 24. Miscellaneous. (a) If any term or provision of this Agreement is held to be illegal, invalid, or unenforceable, the legality, validity, and enforceability of the remaining terms and provisions of this Agreement shall not be affected thereby, and in lieu of each such illegal, invalid, or unenforceable term or provision, there shall be added automatically to this Agreement a legal, valid, and enforceable term or provision as similar as possible to the term or provision declared illegal, invalid, or unenforceable; PURCHASE AND SALE AGREEMENT - PAGE 15 16 (b) Either Seller or Purchaser shall have the right to waive any requirement contained in this Agreement, which is intended for the waiving Party's benefit, but except as otherwise specifically provided herein, such waiver shall be effective only if in writing and executed by the Party for whose benefit such requirement is intended; provided however, that any such waiver shall not be construed as a waiver of any other benefit accruing to the waiving Party hereunder; (c) The captions used in connection with this Agreement are for convenience only and shall not be deemed to expand or limit the meaning of the language of this Agreement; (d) Words of any gender used in this Agreement shall be held and construed to include any other gender, and words in the singular shall be held to include the plural, unless the context otherwise requires; (e) Seller agrees that, on or before the Closing, it will not carry on any negotiations with any third party, for the sale or transfer of the Property, without the prior written consent of Purchaser.
