Exhibit 2.3 (on DPAC Letterhead) March 7, 2005 Mr. Steven D. Runkel Chief Executive Officer and President QuaTech, Inc. 5675 Hudson Industrial Parkway Hudson, Ohio 44236 Dear Steve: By way of this letter, DPAC Technologies Corp., a California corporation headquartered in Orange County, California ("DPAC") is expressing interest in acquiring all of the shares and options of QuaTech, Inc., an Ohio corporation headquartered in Hudson, Ohio ("QuaTech"). The parties anticipate that the proposed acquisition would close on or before July 15th, subject to the various approvals and other conditions described herein. The structure of the transaction will be based on advice from our respective financial advisors, attorneys and accountants but will have the effects set forth below. Both parties herein envision the transaction would be based on the following terms: 1. Acquisition. DPAC would acquire all QuaTech shares, warrants and options for an aggregate number of common shares of DPAC equal to one and one-half (1.5) times the sum of (a) the number of shares of Common Stock of DPAC outstanding at the effective time plus (b) a number of shares that would be issuable upon a "net exercise" of all in-the-money options and warrants of DPAC, based on a market price per DPAC common share at which any new equity financing, as required in Section 4h.(i) below, is obtained. Provided, however, shares issued or reserved and issuable in connection with borrowing or sales of New Securities as contemplated by Section 4h.(i) below, shall be eliminated from both party's outstanding or issuable shares before calculating the foregoing. 2. Due Diligence. Each party will complete a due diligence review within thirty (30) days after execution of this letter for the purpose of verifying each other's financial condition and prospects. Each party agrees for itself that it will schedule a due diligence review team to begin as soon as practicable after execution of this letter, and the party also will make its own books and records and facilities reasonably available to the other, and will make available upon reasonable notice its board members and executives as well as such data as is reasonably requested of them by the other party or its agents or representatives. 3. Preservation of Assets and Business. From the date of this letter until the completion of the due diligence review, set forth in Section 2 above, both DPAC and QuaTech will use reasonable efforts to preserve and maintain the assets and business of the Companies as presently conducted. DPAC will use best efforts to maintain its common shares' Nasdaq Small Cap listing. 4. Definitive Agreement. Concurrent with the due diligence, the Parties will prepare and negotiate an appropriate Agreement and Plan of Merger ("Definitive Agreement") between DPAC and QuaTech. The Definitive Agreement will provide that consummation of the transaction is subject to customary terms and conditions for such transactions and include provisions concerning the following matters: a. Representations, warranties, and covenants of the parties as are normal and appropriate for a transaction of the type contemplated herein with the representations, warranties and covenants expiring upon the closing (the "Closing") of the Definitive Agreement. b.
