("Purus") is pleased to confirm its commitment to make funds available to provide additional debt financing to Casa Solaz, Inc., a Nevada corporation (the "Company"), in the amount of $2,200,000 on the same terms as the existing loan between the parties. Purus is prepared to make this commitment in reliance on the agreement of the Company's holders of capital stock to exchange their shares for Purus common stock (the "Acquisition") subject to the terms and conditions contained herein and in the attached Summary of Proposed Terms and Conditions (the "Term Sheet"). (This letter and the Term Sheet are sometimes collectively referred to herein as the "Letter"). Any capitalized term used and not otherwise defined herein shall have the meaning ascribed to such term in the Term Sheet. The commitment of Purus hereunder is based upon the financial and other information regarding the Company and its subsidiaries provided to Purus and is subject to the various conditions precedent described in the Term Sheet and to the usual reservations, among others, that there shall not have occurred after the date of such information, in the sole opinion of Purus, either any material adverse change in the business, assets, liabilities (actual or contingent), operations, conditions (financial or otherwise) or prospects of the Company and its subsidiaries taken as a whole, or any changes in governmental regulations, monetary policy or market conditions. If the continuing review by Purus of the Company discloses information relating to conditions or events not previously disclosed to Purus or relating to new information or additional developments concerning conditions or events previously disclosed to Purus that Purus in its sole discretion believes may have a material adverse effect on the condition (financial or otherwise), assets, properties, business operations or prospects of the Company and its subsidiaries taken as a whole, Purus, may, in its sole discretion, decline to provide the Financing or complete the Acquisition. The Company hereby represents, warrants and covenants to Purus that (i) all information, which has been, or is hereafter, made available to Purus by the Company or any of its representatives in connection with the transactions contemplated hereby ("Information"), is, and will be, complete and correct in all material respects and does not, and will not, contain any untrue statement of a material fact or omit to state a fact necessary to make the statements contained therein not misleading and (ii) all financial projections concerning the Company that have been, or are hereafter, made available to Purus by the Company or any of its representatives (the "Projections") have been, or will be, prepared in good faith based upon reasonable assumptions. The Company also agrees to furnish Purus with such information and Projections as it may reasonably request and to supplement the Information and the Projections from time to time, through and including the closing date of the Acquisition (the "Closing Date"), so that the representation and warranty set forth in the preceding sentence is correct on the Closing Date. Each of the parties hereto agree that the other party shall (i) have no liability (whether direct or indirect, in contract or tort or otherwise) to security holders or creditors arising out of, related to, or resulting from, the transactions contemplated herein, except to the extent that such liability is found by a judgment of a court of competent jurisdiction to have resulted from gross negligence or willful misconduct or (ii) be responsible or liable for any consequential damages that may be alleged as a result of this Letter. The provisions of the immediately preceding paragraph shall remain in full force and effect regardless of whether definitive documentation for the Financing and Acquisition shall be completed, executed and delivered, and notwithstanding the termination of this Letter or the commitment of Purus hereunder. Please note that, except with respect to the provisions of the preceding two paragraphs, the commitment proposed herein does not constitute a binding obligation of either the Company or Purus, nor does it define all of the terms and conditions of the Financing and Acquisition, but is a framework upon which the documentation for the proposed transactions would be structured, and is a basis for further discussion and negotiation of the terms as may be appropriate. Among other things, the Acquisition would be subject to all of the Conditions Precedent to Closing set forth in the Term Sheet, and those matters which are not covered by or made clear in this Letter are subject to the mutual agreement of the parties. This Letter (i) shall be governed by, and construed in accordance with, the laws of the State of California, without regard to any choice-of-law principles thereof, (ii) may be executed in counterparts, which, taken together, shall constitute an original, (iii) shall be amended or modified only in a writing executed by the parties hereto, (iv) shall not be assigned or transferred by the Company (whether by operation of law or otherwise) without the prior written consent of Purus, and (v) supersedes and replaces any and all proposals or commitment letters previously delivered by Purus to the Company. In addition, no party has been authorized by Purus to make any oral or written statements inconsistent with this Letter. The commitment proposed herein will be available for acceptance until 5:00 p.m. (Pacific Daylight Savings time) on April 17, 1998, unless further extended in writing by Purus. We are delighted to have this opportunity to work with you. If the terms of the Letter meet with your approval, please indicate your acceptance by signing and dating the enclosed copy of this Letter, and then returning the same to the undersigned.
