RECITALS WHEREAS, TRI and its affiliates have spent significant time and resources in developing a project to explore for oil and gas in a designated area within LaSalle County Texas ("Davidson Project"), as more fully detailed in the annexed Exhibit 1 hereto; and WHEREAS, TRI desires to obtain funding for Bellows Well #1 within the Davidson Project, and Enficon is desirous of funding Bellows Well #1 and gaining an economic interest in Bellows Well #1. NOW, THEREFORE, TRI, TIC and Enficon agree as follows: 1. The Parties. TRI is the general partner of TexTerra Exploration Partners, L.P., a Delaware limited partnership ("TexTerra") formed by TRI to work on the Davidson Project. Enficon will gain an economic interest within TexTerra as a limited partner of TexTerra and will have the economic interest limited to Bellows Well #1 within TexTerra as specified in Section 3 below. TRI shall have the full authority of a general partner under the Delaware Limited Partnership Act to make decisions and take actions on behalf of TexTerra. 2. Contributions of the Parties. (a) The January 10, 2006 agreement ("Davidson Agreement") is attached hereto as Exhibit 1, and is incorporated herein by reference. (b) TRI will provide operational and professional support to TexTerra, and will cause TIC to perform the STeP(TM) process for certain mapping and analysis of satellite and geological data in furtherance of the Davidson Agreement for the Bellows Well #1 ("the "Bellows Well #1") (as such term is defined herein). Enficon will reimburse TRI for 80% (eighty percent) of the budgeted costs for the Bellows Well #1, presently estimated as $1,133,720 for the estimated amount of such 80% in the budget for Bellows Well #1 reflected in the approval for expenditure ("AFE") (See Exhibit 2); and for the expenditures for professional fees including TexTerra'a oil and gas consultant, legal costs, title review fees, the costs of TIC's STeP (TM) studies, and additional cash calls made by TRI as general partner to cover the direct costs from third parties directly related to the Bellows Well #1 including, but not limited to, those arising out of changes to the drilling plan and those to the AFE. (c) TRI will, on behalf of TexTerra, monitor the performance of work on, and, if successful, the operation of the Bellows Well #1 and shall utilize such services of third party advisors, including engineering, accounting and legal, as TRI deems reasonable and necessary. TRI will maintain updated technical and financial analysis for the Bellows Well #1, negotiate with the potential parties interested in farmin interest(s) as to Bellows Well #1, negotiate, if appropriate in TRI's judgment, with third-party financing sources and take such other actions as it deems advisable in protecting the interests of TexTerra in Bellows Well #1. (d) Enficon shall, on or before February 3, 2006, deposit $1,133,720 ("Davidson Escrow Amount") into the escrow account of the Law Offices of Dan Brecher, as required pursuant to the Davidson Agreement ("Davidson Escrow Agreement") to fund the initial estimated costs of the Bellows Well #1 described in section 2 (b) above, and in accordance with the Davidson Agreement and the related "AFE," as such term is defined in the Davidson Agreement. To the extent that TRI or a related party has already funded a portion of the Davidson Escrow Amount, Enficon shall at the written direction of TRI (accompanied by a notarized letter from the escrow agent acknowledging the receipt of an amount equal to such portion of the Davidson Escrow Amount from TIC, TRI or other related party), pay such portion of the Davidson Escrow Amount to TIC, provided that $283,430 is deposited by TIC into the HSBC account established for TexTerra for TRI's 20% portion of TexTerra'a payment of the initial estimated Bellows Well #1 budget of $1,417,150. Enficon, or a designee thereof, shall be a required signator on such TexTerra account holding the remaining portion of the Davidson Escrow Amount. (e) If, for any reason, additional funding is required for the Bellows Well #1 beyond the initial $1,417,150 estimated budget for the Bellows Well #1 or costs provided for herein, TRI and Enficon shall be responsible for such additional costs in the ratio of 20% to 80%, respectively. Enficon shall not have responsibility for, nor any interest in, any other well or other asset or revenue in TexTerra, other than the Bellows Well #1. (f) If Enficon fails to timely pay the amount set forth in Section 3 (d) when due, TIC and its affiliates shall have the right, but not the obligation, to deem the convertible debentures of CompuPrint ("CPPT") issued to Enficon reduced by the unpaid amount of the Section 2(d) amount, plus interest and costs, and to deem the remaining Enficon convertible debentures converted into CPPT stock at the greater of $1 per share or the average closing asked price for CPPT stock in the OTC Bulletin Board market for the day preceding the default, the day of the default and the day following the default by Enficon. Enficon represents that it has not assigned or transferred to anyone else any of the CPPT debentures issued to Enficon. 3. Economic Interest of Enficon and TRI. (a) Enficon's interest in TexTerra in relation to the Bellows Well # 1 is and shall be limited to the right to 65% of the Net Revenue Interest in Bellows Well # 1 received by TexTerra after the Overriding Royalty specified in Section 3 (b) below, and TRI shall receive the remaining 35% portion of the Net Revenue Interest received by TexTerra in relation to the Bellows Well #1. (b) For purposes hereof, the overriding royalty interest to be paid to TIC ("Overriding Royalty") shall be calculated as 5% (five percent) of 8/8ths of the working interest in the Bellows Well #1, and of such other revenue to TexTerra, if any, as may result. (c) All other interests in any other wells or projects of TexTerra shall be deemed "Non-Participating Projects" and "Non-Participating Farmout Interests" in and to which Enficon shall have no interest or rights.

Leases, La Salle County, Texas Gentlemen: This letter agreement ("Farmout Agreement"), when signed by you in the space provided below, will constitute an agreement between Davidson Energy, L.L.C. ("Davidson"), Johnson Children's Trust No. 1 ("Trust") and TexTerra Exploration Partners LP ("TTEP") regarding the development of the Richard Bellows et ux. 1280-acre oil and gas lease dated April 27, 2005, recorded at Volume 451, Page 422, Official Public Records, La Salle County, Texas, covering two 640 acre tracts in Survey 158, H. & G.N.R.R. Co., A-1076, Patent No. 508, Vol. 14, and in Survey 157, H. & G.N.R.R. Co., A-276, La Salle County, Texas (the "Bellows Lease"). The Bellows Lease was assigned by the original lessees, Darrel Canion and Marian Canion, to Davidson and Trust subject to a reserved overriding royalty interest equal to the difference between 25% net revenue interest and existing landowner royalties. The Bellows Lease does not cover 100% of the mineral fee estate and three (3) additional leases have been negotiated with the remaining mineral fee owners, being Main Plaza Corporation, Jarret B. Meuth and William R. Meuth, Jr. (collectively, the "Mineral Owner Leases"). The Bellows Lease and the Mineral Owner Leases are collectively referred to as the "Leases". Davidson shall bear the initial acquisition costs of the Mineral Owner Leases at its sole expense, not subject to reimbursement. 1. Interests to be Purchased/Purchase Price. Subject to the conditions set forth herein, Davidson and Trust shall assign to TTEP a 70% (Seventy Percent) working interest (the "TTEP Initial Well Interest") in and to the Railroad Commission spacing unit ("Spacing Unit") surrounding the initial well (the "Initial Well") to be drilled on the Leases. The Initial Well is to be drilled to an approximate depth of 7,500 feet subsurface pursuant to the AFE (as defined below) and the JOA (as defined below). The purchase price for the TTEP Initial Well Interest shall be (i) TTEP's agreement to pay 100% (One Hundred Percent) of the actual costs up to the dollar limit ("Dollar Limit") stated in the Approval for Expenditure ("AFE") for drilling, testing, stimulating, completing and equipping (including tie in to sales lines) the Initial Well as a producing well through the tanks (if an oil well) or through the pipeline connection (if a gas well), as specified in the AFE, unless the election is made to plug and abandon the Initial Well, in which case the purchase price for the TTEP Initial Well Interest shall be the actual costs of drilling, testing, and plugging the Initial Well, plus any costs related to surface restoration surrounding the Initial Well which is required by the Bellows Lease. Any additional costs over the Dollar Limit shall be paid 70% (Seventy Percent) by TTEP and 30% (Thirty Percent) by Davidson. The remaining 30% (Thirty Percent) working interest in the Spacing Unit shall be retained by Davidson and Trust. The net revenue interest ("NRI") which shall be attributable to holders of all of the working interest shall be not less than 75% (Seventy Five Percent). All reasonable efforts will be made to spud the Initial Well by January 31, 2006, subject to drilling rig and other long lead time items' availability. The parties agree that the drilling operations shall be conducted on the Initial Well by Alamo Operating Company, L.C. ("Alamo Operating") subject to the terms of a separate agreement with Alamo Operating for such services. 2. Escrow; Use of Funds. (a) Within one (1) business day after the satisfaction of the conditions stated in paragraph 7 below, TTEP shall deposit in cash by wire transfer to Dan Brecher, Attorney at Law ("TTEP's Agent") a sum equal to the costs of drilling to completion the Initial Well, as reflected by the AFE approved by the parties: Law Offices of Dan Brecher Citibank, 90 Park Avenue New York NY 10016 Account number 95050499 ABA No.: 021000089 TTEP's Agent (as instructed by TTEP) shall immediately thereupon distribute the funds necessary to satisfy Alamo Operating's funding requirements for drilling the Initial Well, including immediate deposit with Alamo Operating of all dry hole costs required by Alamo Operating and any other advance deposits required by Alamo Operating under the terms of its operating contract. (b) Additional funds may be cash called as necessary, subject to the agreements between the parties, including the separate agreement with Alamo Operating. (c) In the event that the Initial Well is plugged and abandoned as a dry hole prior to a completion attempt, then TTEP's Agent and, if applicable, Alamo Operating shall refund to TTEP, 100% (One Hundred Percent) of all cash remaining after payment of the approved costs of drilling, plugging and abandoning the well bore and restoring the surface of the Initial Well Spacing Unit. (d) The funds deposited by TTEP shall be used solely for the purposes set forth in the AFE agreed by the parties, which shall include road work, site preparation, drilling of a water well and drilling, completing and equipping (or plugging and surface restoration, if applicable) on the Leases. Davidson and Trust may suggest the use of their affiliates to perform needed services at competitive rates, but neither party shall be bound to utilize such services of the affiliates. 3. Operations, Selection of Drillsite and Drilling Specifications. (a) Alamo Operating shall be the operator of record. Should Alamo Operating fail or refuse to serve as operator, Davidson, Trust and TTEP shall mutually agree upon an operator of record. All operations, including the Initial Well and future wells, will be subject to a Model Form Operating Agreement to be executed by the parties with appropriate COPAS exhibit and other exhibits naming Alamo Consulting as operator (the "JOA"). (b) TTEP, through its affiliate, Terra insight Corporation, shall select the location for the Initial Well and every subsequent well within the subject lease provided on average 3 out of 5 drilled oil or gas wells are productive. Alamo Operating shall communicate its proposed drilling procedures and techniques for the Initial Well to TTEP in advance and TTEP shall have the right to alter such procedures and techniques as it deems necessary to maximize the likelihood of drilling success. TTEP may, at its election and at its sole risk, maintain a drilling representative on the derrick floor or the Lease to monitor operations and to make elections, as appropriate. The parties agree that Alamo Operating or any successor operator shall be required to provide daily reports while undertaking well drilling, completion, or workover operations and weekly reports to the working interest holders regarding all other operations. 4. Assignment of the TTEP Lease Interest. The TTEP Initial Well Interest and the TTEP interest in the remaining acreage under the Leases shall, subject to the Leases, be considered to be earned at the later to occur of (a) deposit by TTEP with TTEP's Agent of the costs of drilling the Initial Well to (dry hole + contingency) completion as reflected in the approved AFE, or (b) the deposit by TTEP's Agent from the Escrow the Initial Well dry hole costs with Alamo Operating per Alamo Operating's requirements, at which time Davidson/Trust shall deliver a fully executed and recordable assignment covering the Leases which conveys to TTEP a Seventy Percent (70%) working interest in the Initial Well Spacing Unit and a Fifty Percent (50%) working interest in all other acreage covered by the Leases, subject to the adjustment of working interest between the parties described in paragraph 5 below should Davidson/Trust elect not to participate in a future well and to instead elect to be carried, as therein described. TTEP agrees that it will timely provide Davidson with sufficient Initial Well drillsite information in advance of this assignment obligation that will permit Davidson to survey the Initial Well Spacing Unit perimeter and to generate metes and bounds field notes for such Initial Well spacing unit which are to be attached to the assignment as a part of the legal description of the Leases. After the Initial Well is drilled and then either plugged and abandoned or completed as a producer, TTEP will have completed all earning obligations on the Lease. Each working interest owner shall have the right to separately market its proportionate share of production from the Initial Well. 5. Participation in Future Wells. (a) Davidson and Trust agree, that after the Initial Well, each party has the right but not the obligation to participate in future wells on the Lease, subject to the JOA, The extent of the participation by the participating party shall be 50% (Fifty Percent) working interest (unless Davidson/Trust elects to be carried as described in subparagraph 5(b) below). The contributing participation cost of each party shall be governed by the JOA. (b) In the event Davidson and the Trust together decide not to participate in a future well or wells on the Lease, Davidson/Trust shall promptly deliver a recordable assignment of their working interest in and to the Leases as to the spacing unit assigned to the proposed well, reserving therefrom only a back-in 10% (Ten Percent) working interest ("Backin Interest") which shall become effective if and when TTEP reaches cumulative payout on the Lease, according to the formula below. TTEP may assign its 100% (One Hundred Percent) working interest in the particular spacing unit at any time, subject to protection of the Backin Interest, and subject to the limitations upon assignment set forth in the particular Leases. (c) Payout shall be deemed to have occurred as of the first day of the month following the month in which the result of the following formula is equal to or greater than one: TTEP cumulative net production revenue (from Initial Well plus wells subject to Backin Interest) divided by TTEP cumulative cost (from Initial Well plus wells subject to Backin Interest) 6. Representations and Covenants by Davidson. (a) Davidson represents that neither it or its employees, executives or other affiliates hold any beneficial interest in the Leases except as specified herein. (b) In the event that the rig is not available to be delivered to the Initial Well site within existing terms of the Leases, Davidson covenants to obtain a written extension to the term of any Lease prior to its scheduled expiration. Such extension shall be obtained at no additional cost to TTEP. (c) Davidson covenants to promptly apply for permits for a water well and road work and to complete these projects in a prompt workman-like manner once the necessary permits are obtained. (d) Davidson covenants to advise TTEP of the available lease terms for offset leases on the play trend when that information becomes available. If negotiations for offset leases are initiated by Davidson, then Davidson agrees to attempt to obtain leases with minimum two year terms and net revenues of at least 80%, plus the ability to hold such leases, if any are secured, by commencement of drilling to a maximum depth of 8,000 feet.
