       RE:    PROPOSED ACQUISITION OF ZIM TECHNOLOGIES INTERNATIONAL, INC.
              ("ZTI") BY PRIVATE CAPITAL INVESTORS, INC. ("PCI")

Dear Dr. Cowpland:

         This letter confirms the understanding of ZTI and PCI with respect to
the proposed acquisition of ZTI by PCI (the "Acquisition").

         This letter contains only a general summary of the terms of the
Acquisition and certain related transactions, and, except as provided in
Sections 7, 8, 9 and 10 below, is not intended as a binding agreement or an
agreement to agree. The definitive terms of the Acquisition and the related
transactions will be contained in a formal and binding acquisition agreement
(the "Acquisition Agreement") which will contain representations, warranties,
covenants, indemnifications and other provisions which are acceptable to the
parties in their sole discretion.

         1.       TERMS OF ACQUISITION.

                  PCI will acquire ZTI by purchase of all of the issued and
outstanding shares of ZTI, pursuant to which the shareholders of ZTI will
exchange their shares in ZTI for shares in PCI. The Acquisition is intended to
qualify as a tax-free transaction under Canadian law. The total issued and
outstanding shares of PCI following the Acquisition will consist of 38,386,376
shares, with 32,850,921 common shares to be held by the current ZTI
shareholders, approximately 4,000,000 common and special shares to be held by
the Investors (as defined below) and 1,535,455 common shares to be held by the
current PCI shareholders. All outstanding options to purchase shares of the
common stock of ZTI held by officers, directors, employees and consultants of
ZTI shall be exchanged for options to purchase an equal number of shares of the
common stock of PCI. The exercise price of the options will remain at the
current exercise price of CDN 1.00 per share.

         2.       STRUCTURE OF ACQUISITION AND RELATED TRANSACTIONS.

                  The parties anticipate the Acquisition and related
         transactions will involve the following principal steps:

                  (a) STOCK SPLIT. PCI will effect a stock split (the "Stock
         Split"), so that PCI will have 1,535,455 common shares. At the
         effective date of the Continuance, PCI's current shareholders will hold
         these shares in the amounts set forth on Appendix A to this letter.

                  (b) ESTABLISHMENT OF SECONDARY MARKET IN PCI SHARES. PCI will
         contact one or more market makers to establish a secondary market for
         the shares of PCI, provided that ZTI has first approved such market
         makers. One of these market makers will submit information regarding
         PCI on Form 211 to NASDAQ to permit trading of the shares of PCI
         through the OTC Bulletin Board. At the present time, a portion of the
         PCI shares held by the current PCI shareholders may be resold to the
         public under Rule 144 under the Securities Act of 1933, as amended (the
         "Securities Act"). It is anticipated that the current shareholders of
         PCI will sell a portion of these shares to the public in order to
         initiate public trading in the shares of PCI, subject to the
         limitations set forth in Section 3(a).

                  (c) PURCHASE OF SHARES IN ZTI BY INVESTORS. A group of
         Canadian investors (the "Investors") will purchase up to CDN4,000,000
         of the common and special shares of ZTI. Each special share will
         convert into one common share of ZTI under certain conditions. As part
         of the purchase, ZTI will agree that the Investors will receive
         registration rights from PCI as part of the Acquisition. The sale of
         the shares will be an exempt transaction under Section 72(1)(d) and (p)
         of the SECURITIES ACT (Ontario).

                  (d) CHANGE OF PCI'S NAME. PCI will change its name to one
         selected by ZTI. PCI will use its best efforts to complete the name
         change as soon as possible, but in no event later than the closing of
         the Acquisition.

                  (e) DUE DILIGENCE INVESTIGATIONS. The parties will undertake
         due diligence investigations of each other.

                  (f) NEGOTIATION AND EXECUTION OF DEFINITIVE ACQUISITION
         AGREEMENT. After the completion of due diligence investigations, the
         parties will negotiate and execute the definitive Acquisition
         Agreement.

                  (g) PREPARATION OF REGISTRATION STATEMENTS. PCI will prepare
         registration statements to be filed with the Securities and Exchange
         Commission (the "SEC") with respect to the transactions contemplated by
         this letter. PCI will file these registration statements with the SEC

         after the execution of the definitive Acquisition Agreement. The
         purpose of the registration statements will be:

                  (i)      to register the distribution of the PCI shares
                           currently held by Global Intermatch Corp. ("Global")
                           to Global's shareholders (the "Spinoff");

                  (ii)     to register the shares in PCI which will be deemed to
                           be issued to the shareholders of PCI as a result of
                           the continuance of PCI (the "Continuance") under the
                           Canadian Business Corporation Act ("CBCA"); and

                  (iii)    to register the issuance of the shares of PCI to be
                           issued to the current shareholders of ZTI and the
                           Investors pursuant to the Acquisition. PCI will file
                           a similar document with the Ontario Securities
                           Commission ("OSC") as its preliminary prospectus
                           qualifying the conversion of the ZTI special shares
                           into common shares.

                  (h) SPINOFF OF PCI SHARES BY GLOBAL. Global will distribute
         89,000 of its PCI shares to its shareholders. PCI will register the
         distribution of the shares by Global under the Securities Act on Form
         SB-2 to be filed with the SEC.

                  (i) CONTINUANCE. Prior to the consummation of the Acquisition,
         PCI will file articles of continuance under the CBCA. As part of the
         Continuance, PCI will change its name to one selected by ZTI. PCI will
         register the Continuance under the Securities Act or Form S-4 to be
         filed with the SEC.

                  (j) ACQUISITION OF ZTI. After the Continuance of PCI under the
         CBCA, PCI will acquire all of the outstanding shares of ZTI in a share
         exchange pursuant to an offer to acquire all shares of ZTI (a "takeover
         bid" under the CBCA). PCI will register the issuance of its shares to
         the ZTI shareholders under the Securities Act on Form S-4 to be filed
         with the SEC.

                  (k) AMEX LISTING. After a sufficient number of PCI shares are
         resold in the public market, PCI will seek to have its outstanding
         shares listed on AMEX.

         3.       ADDITIONAL AGREEMENTS.

                  (a) LOCK-UP AGREEMENTS WITH CERTAIN PCI SHAREHOLDERS. The
         Acquisition Agreement will provide that the shares of PCI held by
         Stuart Cooper, Cooper Family Holdings, Pasadena Investments, Ltd.,
         Thornhill Consulting, Ltd. and Global will be subject to the following
         resale restrictions:

                  (i)      Except as provided below, the shares may not be
                           resold, without the consent of ZTI, until three
                           months after the listing of PCI's shares on the AMEX.
                           Notwithstanding the foregoing: (i) Global may donate
                           up to 90,000 of its PCI shares to one or more

                           89,000 shares of PCI pursuant to the Spinoff; and (v)
                           Cooper Family Holdings or its beneficiaries may sell
                           up to 10,000 of its PCI shares into the public
                           market.

                  (ii)     After the listing of PCI's shares, each shareholder
                           may resell four percent (4%) of their shares each
                           month, with such restrictions expiring two (2) years
                           after the listing of PCI's shares.

                  (iii)    The foregoing limitations are in addition to any
                           restrictions imposed under Canadian law.

                  (b) REGISTRATION RIGHTS. The Acquisition Agreement will grant

Securities Act following the consummation of the Acquisition. The grant of the
registration rights will be subject to customary terms and conditions.
