Suite 1000, Bankers Hall West 888 - 3rd Street, S.W. Calgary, Alberta T2P 5L5 RE: Letter of Intent - Proposed Take-over Bid for the shares of Energy One Resource Services Inc. Gentlemen: Let this Letter of Intent serve to: (a) express the intentions of Cal Alta Auto Glass, Inc., a Nevada corporation (the "Buyer") to purchase (the "Acquisition") all of the issued and outstanding capital stock (the "Shares") of Energy One Resource Services Inc., an Alberta corporation (the "Company") from the Company's stockholders (the "Sellers"); and (b) supersede and replace all prior understandings and discussions that we have had regarding the transactions and matters set forth below. We understand that all of the Company's issued and outstanding capital stock consists of the following common stock and all said stock is held by stockholders who have given you their assurance that they seek to enter into the transaction contemplated by the Acquisition. As presently contemplated, we anticipate that a closing (the "Closing") of the Acquisition transaction contemplated in the definitive agreements for the purchase of the Shares (the "Definitive Agreements") shall occur on or before 2:00 P.M. (Calgary, Alberta time), September 7, 2007, at which time the Definitive Agreements will be executed. In executing this Letter of Intent, the Buyer acknowledges and confirms its intentions expressed herein with respect to the proposed transaction, but (except for the provisions of Paragraphs numbered 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 16 hereof which are intended to be legally binding and enforceable) this Letter of Intent is not intended to constitute a binding contract or to create any legal obligations or rights of any party or non-party within any jurisdiction. The parties hereto further acknowledge and confirm that they seek to complete the contemplated Acquisition under Section 368 of the Internal Revenue Code of 1986, as amended and part 14 of and pursuant to the Securities Act (Alberta) and all other applicable securities laws in Alberta. Further, and prior to the close of the Acquisition, the parties acknowledge and agree that the Buyer shall have the right, at its sole discretion, to divest or make arrangements for the divestiture, in whole or in part, of the Company's assets and business operations on such terms as the Buyer may determine with the consent of the Company (the "Divestiture"). Buyer shall, however, reasonably consult with and advise the Company of any determinations that it makes with respect to the terms, timing, and arrangements in connection with any Divestiture. In the event the parties fail to execute the Definitive Agreements by 2:00 P.M., (Calgary, Alberta time), September 7, 2007 (the "Closing"), regardless of the cause or reason, then this Letter of Intent (except for Paragraphs 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 16) shall terminate automatically and become null and void and of no force or effect as to its intent without liability on the part of any party (or parties), and without further action by the parties or any one of them. At present, on the basis of the information made available to us, we believe that an agreement can be reached upon the following general terms and conditions. 1. Delivery of Shares at Closing by Sellers At Closing (as set forth in Paragraph 6 below), the Company shall cause each of the Sellers to deliver to Buyer all of the Shares of the Company owned and held by the Sellers. All said Shares shall be delivered free of any rights, claims, interests, charges (both legal and equitable) and encumbrances of any third party (including any that may be asserted under any marital or community property laws) ("Encumbrances"). The Company shall, upon request of the Buyer, provide the Buyer with an opinion of its legal counsel that the Shares are and will be at Closing, free of all said Encumbrances. (a) No later than ten (10) days prior to Closing, the Company and each Seller shall confirm the total number of Shares of the Company that are and will be outstanding at Closing and provide the Buyer with instructions for the number of shares of the Buyer's common stock that are to be issued to each of the Sellers in payment of the pro rata Purchase Price to each Seller. 2. Consideration for Shares At Closing and subject to Paragraph 2 of this Letter of Intent, Buyer shall pay such number of shares of Buyer's common stock (the "Purchase Price") as the parties may determine for all of the issued and outstanding Shares of the Company with the amount of the Purchase Price to be paid to each Seller to be determined by the proportion of the number of Shares sold by each Seller divided by the total number of Shares of the Company then outstanding. The parties acknowledge that the number of shares shall be further negotiated. 3. Conditions to Buyer's Obligations to Closing The obligations of the Buyer to consummate the Acquisition is subject to the following conditions: (a) completion of Buyer's Due Diligence, satisfactory to Buyer (in its sole and absolute discretion) including, but not limited to, any pending or threatened litigation or government inquiry or proceeding which could lead to or result in actions to enjoin, challenge, require the payment of damages in connection with the Acquisition, or otherwise result in additional burdens upon the Buyer as a result of the Acquisition; (b) completion of negotiations and execution of the Definitive Agreements and any and all collateral agreements and third party consents prior to September 7, 2007, with representations and warranties, affirmative and negative covenants customary in transactions of this type; (c) a formal take-over bid circular filed and prepared in accordance with applicable securities legislation in Alberta; (d) receipt by Buyer of approval by all state and federal (and also provincial) securities regulatory bodies), as may be needed; (e) the receipt by Buyer of any consents deemed by Buyer as needed or necessary to consummate the Acquisition, unless Buyer waives its right to require any said consents; (f) completion of negotiations and execution of any other agreements with one or more Company officers and employees on terms deemed satisfactory to Buyer; (g) approval of the Acquisition and all transactions contemplated or required to effect the Acquisition, by the Board of Directors of both Buyer and Company (and by the Shareholders of the Company after the Company's Annual General and Special Meeting of its Shareholders to occur on or before August 30, 2007); (h) at Closing, the Company's net working capital (defined as total current assets minus total current liabilities) shall be not less than such amount as the Buyer determines, in the exercise of its reasonable discretion is necessary to ensure that the Company can meet its financial obligations without difficulties; (i) at Closing, the Company's equity (as reflected on its balance sheet of June 30, 2007 and at closing), shall be not less than such amount as the Buyer determines, in the exercise of its reasonable discretion, is necessary to ensure hat the company can meet its financial obligations without difficulties. 4.
