Re:  Settlement Agreement and Release of All Claims

Dear Bill:

     This letter confirms the settlement terms that you and I have negotiated
regarding any and all disputes relating to your employment with Onesoft Corp,
(Onesoft), formerly Global Exchange, Incorporated, which shall be deemed for
purposes of this Settlement Agreement and Release of All Claims to include and
any of its current or former divisions, affiliates, subsidiaries and related
entities, and its and their respective current or former officers, directors,
employees, agents, successors and assigns, including specifically and without
limitation, Mr. William L. Robertson, (the "Company"). As more fully set forth
below, the Company shall provide you with settlement pay in exchange for certain
agreements by you.

     1.   Settlement Pay. Commencing on the fifteenth of the month after ONESOFT
          ---------------
receives a copy of this Agreement executed by you (the "Effective Date"), the
Company will provide you with the following Settlement Pay:

     (i)  Settlement Pay in the gross amount of $80,000.00 (less state, federal
          and other employment related deductions) shall be in sixteen (16)
          equal installments of $5,000 (less deductions) pursuant to a monthly
          schedule to be determined by the Company, provided, however, that the
          Company shall make such installment payments in at least sixteen (16)
          of the twenty (20) months that follow payment of the first installment
          and shall have paid the full amount of Settlement Pay ($80,000 less
          deductions) within twenty (20) months of the date it pays the first
          installment. The first and second installments shall be paid to the
          law firm of Mason, Ketterman, & Morgan. All subsequent installments
          shall be paid directly to you. The first installment shall be paid on
          the seventeenth day of July, 1997. In any subsequent month in which
          ONESOFT elects to make a payment, it shall pay the installment by the
          fifteenth day of the month.

     (ii) ONESOFT agrees to make an additional payment of $30,000 to you within
          sixty (60) days of any initial public offering or acquisition of
          ONESOFT. For the purposes of this Section 1(ii), an acquisition shall
          be defined as the acquisition of fifty-one percent or more of the
          Company by a third party entity.

     You acknowledge and agree that the Settlement Pay provided herein is not
otherwise due or owing to you under any Company employment agreement (oral or
written) or Company policy or practice, nor is this Settlement Pay intended to,
and shall not, constitute a severance plan, and shall confer no benefit on
anyone other than the parties hereto. You further acknowledge that except for
the specific financial consideration set forth in this Agreement, you have
<PAGE>

been paid and provided all wages, commissions, bonuses, vacation pay, holiday
pay and any other form of compensation or benefit that may be due to you now or
which would have become due in the future in connection with your employment
with or separation of employment from the Company.

     2.   Confidentiality: You hereby agree and acknowledge the following:
          ---------------

     (i)  that you have returned to the Company all of its documents (and any
     copies thereof) and property, and that you otherwise shall abide by any and
     all common law and/or statutory obligations relating to the protection and
     non- disclosure of the Company's trade secrets and/or confidential and
     proprietary documents and information;

     (ii) that all information relating in any way to the subject matter of this
     Agreement, including the terms, amounts and fact of this Agreement, shall
     be held confidential by you and shall not be publicized or disclosed to any
     person (other than an immediate family member, legal counsel or financial
     advisor, provided that any such individual to whom disclosure is made
     agrees to be bound by these confidentiality obligations), business entity
     or government agency (except as mandated by state or federal law).

     3.   No Disparagement. You hereby agree that you will not make any
          ----------------
statements that are professionally or personally disparaging about, or adverse
to, the interests of the Company including, but not limited to, any statements
that disparage any person, product, service, finances, financial condition,
capability or any other aspect of the business of the Company, or engage in any
conduct which is intended to harm professionally or personally the reputation of
the Company.

     ONESOFT hereby agrees that the Officers, Directors, and Employees of the
Company will not make any statements that are professionally or personally
disparaging about, or adverse to your interests, including, but not limited to
any statements that disparage you personally or professionally. Nor shall the
Officers, Directors, or Employees of the Company engage in any conduct which is
intended to harm your reputation, professionally or personally.

     4.   Release of Claims: You hereby agree and acknowledge that by signing
          ------------------
this letter and accepting the offer of Settlement Pay provided for in Section 1
and other good and valuable consideration provided for in this letter, you are
waiving your right to assert against the Company any form of legal claim of any
kind whatsoever from the beginning of time through the Effective Date of this
Agreement. Your waiver and release herein is intended to bar any form of legal
claim, charge, complaint or any other form of action (jointly referred to as
"Claims") against the Company seeking any form of relief, including, without
limitation, equitable relief (whether declaratory, injunctive or otherwise), the
recovery of any damages or any other form of monetary recovery whatsoever
(including, without limitation, back pay, front pay, compensatory damages,
emotional distress damages, punitive damages, attorneys fees and any other
costs) against the Company, from the beginning of time through the Effective
Date.

     Without limiting the foregoing general waiver and release, you specifically
waive and release the Company from any Claim arising from or related to your
employment relationship with the Company, the offer thereof or the termination
thereof, including, without limitation:
