                                  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. Reasonable assurances/verification that prior to consummation of a
     transaction, both businesses shall have been conducted in all aspects in
     the ordinary course and consistent with past practices consistently
     applied.

          c. Shareholder Agreements between DPAC and Development Capital
     Ventures, LP, HillStreet Fund, L.P., William Roberts and Steve Runkel
     committing to vote for and cooperate in the closing of the transaction.

          d. DPAC and QuaTech shall have received all permits, authorizations,
     regulatory approvals and third party consents legally required for the
     consummation of the transactions, and all applicable legal requirements
     shall have been satisfied.

          e. The Board of Directors and shareholders of QuaTech, and the Board
     of Directors and shareholders of DPAC, shall have approved the Definitive
     Agreement in accordance with applicable law.

          f. Each party will be responsible for its own legal, accounting, and
     transaction costs.

          g. DPAC will form a subsidiary to merge with QuaTech, and the
     transaction will be structured as a tax-free reorganization pursuant to
     Internal Revenue Code Section 368, and, if practicable and consistent with
     reorganization treatment under Section 368, QuaTech's corporate existence
     will be preserved in the merger.

     working capital balances as of closing which will be determined by the
     parties, (iii) QuaTech shall have paid and discharged its mezzanine loan at
     Closing out of available transaction funds of the combined company, (iv)
     holders of QuaTech warrants shall have agreed to convert such warrants into
     common stock of DPAC upon consummation of the merger as if such warrants
     were converted to common stock of QuaTech immediately prior to the Closing,
     (v) the holder of QuaTech's preferred stock shall have agreed to convert
     such preferred stock into common stock of DPAC upon consummation of the
     merger as if such shares of preferred stock were converted into common
     stock of QuaTech immediately prior to the Closing, (vi) each of the parties
     shall have obtained all necessary consents, and (vii) neither of the
     parties shall have suffered a material adverse change in its financial
     condition or business prospects.

          i. As of the Closing, the board of directors of DPAC shall consist of
     seven individuals including, William Roberts, Steve Runkel, Kim Early and
     four independent directors. As of the Closing, Steve Runkel shall be
     employed as the CEO of DPAC, and Kim Early shall continue as a full-time
     employee of DPAC and shall be the Chairman of the Board and a director of
     DPAC. Kim Early's responsibilities shall be finding, planning and, if
     approved by DPAC's Board of Directors, executing DPAC's future acquisitions
     of complementary product lines and businesses, and he shall report to the
     Board of Directors of DPAC.

     Roberts, as QuaTech shareholders receiving shares of DPAC common stock
     (which may be deemed to hold control shares) in connection with the
     transactions contemplated by the Definitive Agreement that provides such
     QuaTech shareholders certain customary demand rights related to the resale
     of such shares.

5.   Confidentiality. Other than planned public announcements subject to Section
     6, with respect to information concerning or relevant to the other party
     and its business and the transaction contemplated herein, including the
     identities of the parties and the fact that the parties are in
     negotiations, each party agrees on behalf of itself that it will hold such
     information in strict confidence and will not disclose any of such
     information other than to its own directors, officers, employees, agents
     and representatives who need to know such information for the purpose of
     evaluating the transaction, who shall be informed by the party of the
     confidential nature of such information and be directed by and agree with
     the party to treat such information confidentially. Provided, however, that
     this paragraph does not apply to the use or disclosure of information which
     (a) was known to the receiving party before receipt thereof from the
     disclosing party; (b) is learned by the receiving party not from the
     disclosing party or its representatives but from another person entitled to

6.   Public Announcement. Any announcement of the transactions contemplated
     hereby by either party must be approved in writing as to content and timing
     in advance by the other party; provided, however, either party may make any
     announcements as required by law.

7.   Exclusive Negotiations. Each party, by execution of this letter, agrees and
     commits that neither party, nor any affiliate, employee, director,
     principal or representative thereof will negotiate, solicit, seek, retain,
     consider, accept or enter into any commitment to consider or accept, nor
     will they assent to, any offer from any party other than the other party
     hereto or its affiliates with respect to any transaction having the effect
     of transferring control of the party, or the goodwill or (other than in the
     ordinary course of business) assets or any portion of such party, to any
     party other than the other party hereto or the shareholders of that party.
     The obligations set forth in this paragraph shall be in full force and

8.   Unique Agreement. The parties agree that the provisions of Sections 5, 6,
     and 7 of this letter grant rights to QuaTech and DPAC which are of a unique
     and special nature. The parties further agree that any violation by QuaTech
     of Sections 5, 6 or 7 or by DPAC of Sections 5, 6, or 7 of this letter will
     result in immediate and irreparable harm to DPAC on one hand or QuaTech on
     the other hand and that in the event of any actual or threatened breach or
     violation of any of said provisions, the non-breaching party will be
     entitled as a matter of right to an injunction or a decree of specific
     performance from any equity court of competent jurisdiction. The breaching
     party hereby waives the right to assert the defense that such breach or
     violation can be compensated adequately with damages in an action at law.
     Nothing in this letter will be construed as prohibiting the non-breaching
     party from pursuing, or limiting the availability of, any other remedies at
     law or in equity available to it for such breach or violation or threatened
     breach or violation.

                                       4
