The persons listed in the shareholder list provided by Entrenaut to CC (the "Entrenaut Shareholder List") are all of the shareholders of Entrenaut. Such persons are referred to herein as the "Acquired Company's Shareholders." Entrenaut is sometimes referred to herein as the "Acquired Company" because the transactions described below will result in the acquisition of all of the issued and outstanding stock of Entrenaut by CC. CC, the Acquired Company, and the Acquired Company's Shareholders are referred to collectively herein as the "Parties" and sometimes individually as a "Party." The Acquired Company's Shareholders may agree to be bound by the terms of this Agreement that are applicable to them by (i) signing a signature page or (ii) signing any other document or agreement that indicates an intention on the part of the signer to be bound by the terms of this Agreement and to approve the transactions provided for in this Agreement. Any Acquired Company's Shareholder may also indicate his, her or its intention to be bound by this Agreement by taking the actions of an Acquired Company's Shareholder as provided for herein, even if the Acquired Company Shareholder does not sign a signature page or undertaking to be bound by this Agreement.

RECITALS A. On December 8, 1999, CC and Entrenaut signed a letter of intent (the "Letter of Intent"). B. The Letter of Intent provides for CC (and its shareholders, as required) following the Closing (defined below) (a) to change the corporate name of CC to Entrenaut, Inc., a Minnesota corporation, (b) to elect a new board of directors selected by Entrenaut, (c) to acquire all of the issued and outstanding stock of Entrenaut in exchange for a number of shares of newly issued and restricted Series C Preferred Convertible Stock (the "Acquisition Stock") of CC that will be issued to the Acquired Company's Shareholders, at the rate of two (2) shares of acquisition stock for each one (1) share of Entrenaut Common stock, (d) to obtain and to accept the resignation of all existing CC officers and directors effective as of the Closing Date (defined below) (e) to complete any and all delinquent regulatory filings for CC (if any), and (f) to provide all requested due diligence materials to Entrenaut, including a representation stating that there is no outstanding or pending litigation against CC, that all regulatory filings have been made as required by applicable law, that CC is in good standing in various states and other matters reasonably required by the Acquired Company. The Acquisition Stock will be issued in exchange for all of the issued and outstanding stock of the Acquired Company (the "Acquired Company's Stock"). After such exchange, the Acquired Company will be a wholly owned subsidiary of CC. C. The Letter of Intent provides for the Acquired Company's Shareholders to transfer to CC, in exchange for the Acquisition Stock, all of the Acquired Company's Stock. D. The Parties wish to enter into this Agreement to definitively provide for several of the transactions that are contemplated in the Letter of Intent. When executed and delivered by the Parties as provided below, this Agreement will supersede and replace the Letter of Intent so far as the transactions provided for in this Agreement are concerned. Other provisions of the Letter of Intent, if any, that are not otherwise provided for in this Agreement, will survive execution of this Agreement by the Parties unless superseded by any other agreements of the Parties.

ARTICLE VII GENERAL PROVISIONS 7.1 COSTS AND FEES. If any Party breaches any term of this Agreement, the breaching Party agrees to pay the non-breaching Party all reasonable attorneys' fees, expert witness fees, investigation costs, costs of tests and analysis, travel and accommodation expenses, deposition and trial transcript costs, court costs and other costs and expenses incurred by the non-breaching Party in enforcing this Agreement or preparing for legal or other proceedings, at the trial or appellate level, whether or not such proceedings are instituted. If any legal or other proceedings are instituted, the Party prevailing in any such proceeding will be paid all of the aforementioned costs, expenses and fees by the other Party, and if any judgment is secured by such prevailing Party, all such costs, expenses, and fees will be included in such judgment, attorneys' fees to be set by the court and not by the jury. References in this paragraph to "legal proceedings" refer to litigation as well as arbitration proceedings and any other similar or related proceedings. 7.2 WAIVER. No delay by a Party in exercising any right or remedy will constitute a waiver of a Party's rights under this Agreement, and no waiver by any Party of the breach of any covenant of this Agreement by the other will be construed as a waiver of any preceding or succeeding breach of the same or any other covenant or condition of this Agreement. 7.3 INDEMNIFICATION. Each Party (the "Indemnifying Party") will protect, indemnify and hold harmless the other Party and its directors, officers, employees, agents, affiliates and representatives (each an "Indemnified Party") against any and all costs, expenses, damages (whether such damages are general, special, consequential, limited, direct or indirect or incidental), liabilities or losses, including attorneys' fees, caused by, for or on account of the Indemnifying Party's negligence, gross negligence or willful misconduct or failure to perform its obligations under this Agreement or the negligence, gross negligence or willful misconduct of the Indemnifying Party's directors, officers, employees, agents affiliates or representatives. (a) If an Indemnified Party intends to seek indemnification under this paragraph from any Indemnifying Party with respect to any action or claim, the Indemnified Party will give the Indemnifying Party notice of such claim or action upon the receipt of actual knowledge or information by the Indemnified Party of any possible claim or of the commencement of such claim or action, which period will in no event be later than the earlier of (i) fifteen business days prior to the last day of responding to such claim or action or (ii) one half of the period allowed for responding to such claim or action or, if no time period for responding exists, as soon as reasonably possible. The Indemnifying Party will have no liability under this paragraph for any claim or action for which such notice is not provided, unless the failure to give such notice does not prejudice the Indemnifying Party. (b) The Indemnifying Party will have the right to assume the defense of any such claim or action, at its sole cost and expense, with counsel designated by the Indemnifying Party and reasonably satisfactory to the Indemnified Party: provided, however, that if the defendants in any such action include both the Indemnified Party and the Indemnifying Party, and the Indemnified Party will have reasonably concluded that there may be legal defenses available to it which are different from or additional to those available to the Indemnifying party, the Indemnified Party will have the right to select separate counsel, at the Indemnifying Party's expense, to assert such legal defenses and to otherwise participate in the defense of such action on behalf of such Indemnified Party. (c) Should any Indemnified Party be entitled to indemnification under this Section as a result of a claim by a third party, and should the Indemnifying Party fail to assume the defense of such claim or action, the Indemnified Party may, at the expense of the Indemnifying Party, contest or, (with the prior consent of the Indemnifying Party, which consent will not be unreasonably withheld) settle such claim or action. Except to the extent expressly provided herein, no Indemnified Party will settle any claim or action with respect to which it has sought or intends to seek indemnification pursuant to this Section without the prior written consent of the Indemnifying Party, which consent will not be unreasonably withheld or delayed. (d) If an Indemnifying Party is obligated to indemnify and hold any Indemnified Party harmless under this Agreement, the amount owing to the Indemnified Party will be the amount of such Indemnified Party's actual out-of-pocket loss, net of any insurance or other recovery. (e) The duty to indemnify under this Agreement will continue in full force and effect for a period of two years with respect to any loss, liability, damage or other expense based on facts or conditions which occurred prior to such termination. 7.4 NOTICES.
