Exhibit 3

PRE-TENDER AGREEMENT

January 18, 2004

Dear Sir:

Re: Offer by Hawker Resources Inc. (“Hawker”) to Purchase all of the Zorin Shares

Reference is made to the Pre-Acquisition Agreement dated January 18, 2004 (the “Pre-Acquisition Agreement”) between Hawker and Zorin Exploration Ltd. pursuant to which Hawker has agreed to make an offer to purchase all of the issued and outstanding Zorin Shares for an ascribed price of $0.40 per Zorin Share to be comprised of, subject to proration and at the election of each depositing Zorin shareholder, either:

(i) $0.40 cash, subject to the Maximum Cash Consideration; or

(ii) that fraction of a fully paid and non-assessable Hawker Common Share as is equal to the Exchange Ratio, subject to the Maximum Share Consideration,

and provided further that in the event the Hawker Average Price is less than $4.75, Hawker shall have the right, but not the obligation, to terminate the Pre-Acquisition Agreement. The Offer price is based on a total of 18,558,000 Zorin Shares being outstanding at the Expiry Time and, to the extent the actual number of Zorin Shares outstanding at such time exceeds 18,558,000, the Offer price shall be reduced proportionately. Unless otherwise defined herein, all capitalized terms referred to herein shall have the meanings attributed thereto in the Pre-Acquisition Agreement.

We understand that you (the “Selling Shareholder”) or your affiliates beneficially own, directly or indirectly, or exercise control or direction over, the number of Zorin Shares set forth in your acceptance at the end of this letter agreement.

This letter agreement sets out the terms and conditions upon which the Selling Shareholder has agreed, among other things, to support the Offer and to deposit under the Offer, or cause to be deposited under the Offer, all of the Zorin Shares held by the Selling Shareholder that are, or will be, beneficially owned or controlled by the Selling Shareholder.

2. Covenants of Selling Shareholder

By the acceptance of this letter agreement, the Selling Shareholder hereby agrees from the date hereof until the earlier of the termination of this letter agreement and the Take-up Date:

(a) not to sell, assign, convey, encumber or otherwise dispose of or relinquish or modify its right to vote any of the Zorin Shares owned by such Selling Shareholder and not to permit any affiliate of such Selling Shareholder to sell,

-2-

assign, convey, encumber or otherwise dispose of or relinquish or modify its right to vote any of the Zorin Shares owned by it (other than to Hawker);

(b) unconditionally and irrevocably to accept and to cause any affiliate of such Selling Shareholder to unconditionally and irrevocably accept the Offer made by Hawker by depositing the Zorin Shares presently owned or hereafter acquired (including any Zorin Shares hereafter acquired pursuant to the exercise of any options to purchase Zorin Shares) by such Selling Shareholder or affiliate not later than 28 days prior to the Initial Expiry Time in the case of Zorin Shares registered in the name of such Selling Shareholder or affiliate, or not later than 3 business days prior to the Initial Expiry Time in the case of Zorin Shares held by a nominee on behalf of such Selling Shareholder or affiliate, and in any event in accordance with the terms and conditions of the Offer;

(c) that they will not exercise any Zorin Options or any Zorin Warrants and that they agree to elect that, in lieu of exercising their Zorin Options, Zorin will pay the positive difference, if any, that results from subtracting from the ascribed purchase price for the Zorin Shares under the Offer the exercise price of their Zorin Options, immediately after the Take-up Date in exchange for the termination of their Zorin Options and Zorin Warrants immediately prior to the Take-up Date;

(d) that all loans made by Zorin to the Selling Shareholder shall be repaid in full on the Take-up Date and that all outstanding amounts shall be netted against any amounts due from Hawker under the Offer to the Selling Shareholder;

(e) not to exercise any statutory or other rights of withdrawal with respect to any Zorin Shares owned by such Selling Shareholder or any affiliate of such Selling Shareholder once deposited pursuant to the Offer unless this letter agreement is terminated prior to Hawker taking up the Zorin Shares under the Offer or if Hawker does not pay for such shares within the period provided for under the Pre-Acquisition Agreement;

(f) not to exercise any shareholder rights or remedies available at common law or pursuant to the Business Corporations Act (Alberta) or applicable securities legislation to delay, hinder, upset or challenge the Offer;

(g) subject to paragraph 5 hereof and except to the extent permitted hereunder, not to take any action, directly or indirectly, which may reasonably be expected to adversely affect the successful completion of the Offer or the purchase of any Zorin Shares under the Offer;

(h) to immediately cease and cause to be terminated any existing solicitation, initiation, encouragement, activity, discussion or negotiation with any parties (other than Hawker) with respect to any Take-over Proposal; and

-3-

(i) not to, directly or indirectly, make, solicit, initiate or encourage (including by way of furnishing information) or participate in or take any other action to facilitate any inquiries or the making of any proposal which constitutes or may reasonably be expected to lead to a Take-over Proposal from any person, or engage in any discussion, negotiation or inquiries relating thereto.

3. Covenants of Hawker

Provided the Pre-Acquisition has not been terminated and that Zorin is not materially in default thereunder:

(a) Hawker shall make the Offer in accordance with the terms and conditions of the Pre-Acquisition Agreement and shall comply with the terms and conditions of Sections 2.1, 9.2, 12.4 and 12.5 thereof in respect of the Offer; and

(b) Hawker shall, subject to the satisfaction or waiver of the conditions set forth in the Offer, take up and pay for all Zorin Shares owned by the Selling Shareholder or any affiliate of the Selling Shareholder deposited pursuant to the Offer, all in accordance with the terms and conditions of the Offer and the provisions of the Pre-Acquisition Agreement.
