         THIS AGREEMENT is entered into as of the date stated below by and among
Xarc Corporation, a Kansas corporation ("Xarc"), Donald I. Wallace, owner of all
of the outstanding shares of Xarc ("Shareholder"), and World Wireless
Communications, Inc., a Nevada corporation ("WWC").

         The parties hereto agree as follows:

A.       FACTS AND OBJECTIVES

         WWC desires to acquire from Shareholder all of the outstanding shares
of Xarc in exchange for certain shares of WWC, and Shareholder desires to
exchange all the shares of Xarc owned by him for shares of stock of WWC,
according to the terms herein.

B.       TERMS AND CONDITIONS

         1. Plan of Reorganization. Shareholder is the owner of all of the
issued and outstanding stock of Xarc, which consists of 1000 shares of common
stock at a stated par value of one dollar per share (the "Xarc Shares"). It is
the intention of the parties hereto that all of the issued and outstanding
capital stock of Xarc will be acquired by WWC in exchange solely for 10,000
shares of the common stock of WWC (the "WWC Shares").

         2. Exchange and Delivery of Shares. WWC and Shareholder agree that the
Xarc Shares will be exchanged with WWC for the WWC Shares. On the closing date,
Wallace will deliver a stock certificate or certificates for all of the
outstanding stock of Xarc, duly endorsed by Wallace so as to make WWC the sole
owner of the Xarc Shares, free and clear of all liens, claims and encumbrances;
WWC shall deliver a certificates of stock totaling 10,000 shares to Shareholder
according to the following schedule:

         Upon closing:                                           2,000 shares
         Within 30 days of closing                               3,000 shares
         By March 31, 1998                                       5,000 shares

The parties may agree to escrow certificates representing such shares as are not
conveyed at the time of closing.

The certificates delivered to Shareholder pursuant to this Agreement shall bear
a legend in substantially the following form (to which terms Shareholder
agrees):

            "The shares of stock represented by this certificate have not been
            registered under the Securities Act of 1933, as amended, or under
            the securities laws of any state. The shares of stock have been
            acquired for investment and may not be sold, offered for sale or
            transferred in the absence of an effective registration under the
            Securities Act of 1933, as amended, and any applicable state
            securities laws, or an opinion of counsel satisfactory in form and
            substance to counsel for World Wireless Communications, Inc. that
            the transaction shall not result in a violation of federal or state
            securities laws."

         3. Representations and Warranties of Shareholder. Shareholder and Xarc
represent and warrant as follows:

            a. That Shareholder is, and will be as of the closing date, the sole
         owner of all of the outstanding shares of Xarc, which shares are and
         will be free from any claims, liens, or other encumbrances, and
         Shareholder has the unqualified right to transfer said shares.
         Shareholder will cooperate with WWC in all steps necessary to assure
         that Xarc satisfies or has satisfied all "good standing" requirements
         of the State of Kansas.

            B. That the Xarc Shares constitute validly issued shares of Xarc,
         fully paid and nonassessable.




            c. That Shareholder has disclosed to WWC all information and
         documents concerning or affecting Xarc's qualifications in the state of
         its incorporation and has further provided to WWC all financial
         statements or balance sheets of Xarc, which statements or balance
         sheets accurately represent the financial condition of Xarc as of the
         date of said statements; there has been no material change in the
         financial condition of Xarc since the date of said statements; there
         are no substantial liabilities, either fixed or contingent not
         reflected in such financial statements other than contracts or
         obligations in the usual course of business; and no such contracts or
         obligations in the usual course of business are liens or other
         liabilities which, if disclosed, would alter substantially the
         financial condition of Xarc as reflected in such financial statements.

            d. That neither Xarc nor Shareholder is involved in any pending
         litigation or governmental investigation or proceeding, and no threats
         or claims of litigation or governmental investigation have been 
         asserted against Xarc, except as set forth at Exhibit A hereto (if
         applicable).

            e. That Shareholder has been supplied with this Agreement and that
         he is familiar with and understands its contents.

            f. That, in determining to acquire the WWC Shares and to enter into
         this transaction, Shareholder has been provided, has obtained and has,
         with due diligence, considered all documents, financial statements,
         disclosures and all other information necessary to Shareholder's
         evaluation of WWC and has relied solely on his own analysis of
         information obtained from WWC and the advice of Shareholder's legal
         counsel and accountants or other financial advisors with respect to the
         tax and other consequences involved in purchasing WWC Shares.

            g. That Shareholder understands and acknowledges that Shareholder's
         rights to and acquisition of the WWC Shares will be governed by the
         terms and conditions of the Agreement.

            h. That the WWC Shares being acquired will be acquired for
         Shareholder's own account without a view to public distribution or
         resale and that Shareholder has no contract, undertaking, agreement, or
         arrangement to sell or otherwise transfer or dispose of any WWC
         Shares or any portion thereof to any person;

            i. That Shareholder (i) can bear the economic risk of the purchase
         and acqusition of WWC Shares, including the loss of the Xarc shares, as
         his entire investment, (ii) has such knowledge and experience in
         business and financial matters as to be capable of evaluating the
         merits and risks of an investment in WWC Shares, (iii) understands that
         there is no guarantee that the actual performance of WWC under any
         circumstances will match and projections which may have been made, and
         that such actual performance may differ substantially from what is
         represented in any such projections.

            j. That Shareholder understands that the WWC Shares have not been
         registered under the 1933 Act or the securities laws of any state and
         are subject to substantial restrictions on transfer as described in the
         Agreement.

            k. That Shareholder agrees that he will not sell or otherwise
         transfer ownership or dispose of any WWC Shares or any portion thereof
         unless (i) such WWC Shares are registered under the 1933 Act and any
         applicable state securities laws or Shareholder obtains an opinion of
         counsel which is satisfactory to WWC that such WWC Shares may be sold
         in reliance on an exemption from such registration requirements, and
         (ii) the transfer is otherwise made in accordance with this Agreement.

            l. That Shareholder understands that (i) WWC has no obligation or
         intention to register any WWC Shares for resale or transfer under the
         1933 Act or any state securities laws or to take any action (including
         the filing of reports or the publication of information as required by
         Rule 144 under the 1933 Act) which would make available any exemption
         from the registration requirements of any such laws and (ii)
         Shareholder therefore may be precluded from selling or otherwise
         transferring ownership of or disposing of any WWC Shares or any portion
         thereof for an indefinite period of time or at any particular time.

            m. That Shareholder has been encouraged to rely upon the advice of
         Shareholder's legal counsel and accountants or other financial advisors
         with respect to the tax and other considerations relating to the
         purchase of WWC Shares and has been offered, during the course of
         discussions concerning the acquisition of WWC Shares, the opportunity
         to ask such questions and inspect such documents (including the books
         and records and financial statements) concerning WWC and its business
         and affairs as Shareholder has requested so as to understand more fully

         Shareholder's net worth and current needs.

            o. That Shareholder understands that no federal or state agency
         including the Securities and Exchange Commission or the securities
         commission or authorities of any state has approved or disapproved the
         WWC Shares, passed upon or endorsed the merits of the Offering, or made
         any finding or determination as to the fairness of the WWC Shares for
         public investment.

            p. That Shareholder understands that the WWC Shares are being
         offered and sold in reliance on specific exemptions from the
         registration requirements of federal and state laws and that WWC is
         relying upon the truth and accuracy of the representations, warranties,
