                           INFINITY INVESTORS LIMITED

                                  April 1, 2002

Edge Technology Group, Inc.

          Re:  Proposed conversion of Promissory Note held by Infinity Investors
               Limited ("IIL") in the principal amount of $219,000 (the "Note")
               issued by Edge Technology Group, Inc. ("Company") into 397,637
               shares of common stock, par value $0.01 (the "Shares") of the
               Company

Board of Directors:

     IIL proposes to convert its Note, the approximate outstanding principal and
interest of which is approximately $258,464.03, into 397,637 Shares (a rate of
$0.65 per share). Such Shares are being issued to and acquired by IIL under the
conditions and upon the representations contained in this letter agreement (the
"Letter Agreement").

     The Company hereby issues and delivers to IIL, and IIL hereby accepts from
the Company 397,637 Shares of the Company in consideration for the cancellation
of the Company's obligations under the Note, including its obligation to pay IIL
approximately $258,464.03 (all of the principal and interest owing thereunder).
ILL shall cancel and deliver the Note on the date that the stock certificates
representing the Shares have been issued to IIL.

     IIL hereby represents and warrant to the Company that:

     (a)  The Shares will be held by IIL subject to all applicable provisions of
          the federal and state securities laws and the rules and regulations of
          the Securities and Exchange Commission.

     (b)  IIL understands that ownership of the Shares involves substantial
          risk. IIL acknowledges that IIL has evaluated such risk and has
          determined that the Shares are a suitable investment. IIL considers
          itself sophisticated in financial and business matters and is capable
          of evaluating the merits and risks of an investment of this type and
          of protecting its own interests in connection with this transaction.

     (c)  IIL understands that the Shares shall bear a restrictive legend which
          prohibits the holder from freely transferring the Shares and that the
          Shares will only be transferable if an exemption from the securities
          laws is available for such transfer.

     (d)  IIL represents that it is an "accredited investor" as such term is
          defined in Rule 501(a) of the Act, because of Section (a)(8) which
          states that an "accredited

Representation Letter - Page 1

          investor" includes "an entity in which all of the equity owners are
          accredited investors."

     (e)  IIL understands that the Company is relying on the accuracy of the
          representations made herein and, but for the existence of this letter,
          the Company would not issue the Shares.

     (f)  IIL or its representatives have been provided access to business and
          financial information regarding the Company and have had the
          opportunity to discuss such information with its advisors to enable
          IIL to make an informed investment decision regarding the conversion
          of the Note into the Shares.

     Miscellaneous

     (a)  This Agreement shall be governed by and construed in accordance with
          the laws of the State of Texas.

     (b)  This Agreement represents the entire agreement between the parties
          with respect to the transaction described herein and, except as
          provided herein, supersedes all previous negotiations, commitments and
          writings with respect to such transaction.

     (c)  The Company's obligations and agreements contained herein are subject
          to the Company's receipt of the Waiver attached hereto as Exhibit A
                                                                    ---------
          executed by all parties thereto.

Surviving Corporation and otherwise to carry out the purposes of this Agreement,
in the name of Visionary or otherwise.

     1.06 Earnout Commissions.
          -------------------

          (a) In the event that the Surviving Corporation's "Gross Revenue" (as
     defined below) during the calendar year 2002 (the "Earnout Period") equals
     to or exceeds Visionary's Gross Revenue for calendar year 2001 as reflected
     in the audited financial statements previously delivered to Edge, then Edge
     shall make an earnout payment (i) in the amount of $250,000 to the
     Visionary Shareholders with (ii) an additional payment in the amount of
     $62,500 for each $250,000 of the Surviving Corporation's Gross Revenue in
     excess of Visionary's Gross Revenue for calendar year 2001, up to a total
     aggregate amount of earnout payments under (i) and (ii) above of no more
     than $500,000 (the "Earnout Commission") payable to the Visionary
     Shareholders as set forth below.

          (b) For purposes of this Agreement, the Surviving Corporation's "Gross
     Revenue" shall mean an amount equal to the audited gross revenue actually
     received by the Surviving Corporation during the Earnout Period, calculated
     in accordance with generally accepted accounting principles.

          (c) Edge shall pay to the Visionary Shareholders an amount in cash
     equal to the Earnout Commission due, if any, by the later of (i) sixty (60)
     days following the end of the Earnout Period or (ii) the final
     determination of the Surviving Corporation's Gross Revenue for the Earnout
     Period.

          (d) Edge and the Visionary Shareholders agree that any Earnout
     Commission will not constitute deferred payment for the Visionary Common
     Stock, but rather shall constitute contingent commissions payable to the
     Visionary Shareholders. Edge and the Visionary Shareholders will report
     such treatment (as ordinary income and ordinary deductions) consistently in
     all federal, state, and local income tax returns filed by any of them.

          (e) As promptly as practicable, but in no event later than thirty (30)
     days after the end of the Earnout Period, Edge shall deliver to the
     Visionary Shareholders a preliminary calculation of the Surviving
     Corporation's Gross Revenue for the Earnout Period.

          (f) Notwithstanding the foregoing, Edge shall be entitled to deduct
     from Earnout Commission due under the provisions of this Section 1.06, all
     amounts resulting from any and all claims, demands, actions, causes of
     action, losses, costs, damages, liabilities and expenses relating to or
     arising out of the Brower Matter, as defined below.

          (c) Peter Gurian shall act as the representative of the Visionary
     Shareholders for purposes of Sections 6.02 and 6.03 of this Agreement (the
     "Claims Representative"), and is duly authorized to be such Claims
     Representative and may bind the Visionary Shareholders. Promptly after the
     receipt by Edge of notice or discovery of any claim, damage or legal action
     or proceeding giving rise to indemnification rights under this Section
     6.02, Edge will give the Claims Representative written notice of such
     claim, damage, legal action or proceeding (for purposes of this Section
     6.02, a "Claim") in accordance with Section 6.02 of this Agreement. Within
     seven days of delivery of such written notice, the Claims Representative
     may, with Edge's written consent, which shall not be unreasonably withheld,
     at the expense of the Visionary Shareholders, elect to take all necessary
     steps properly to contest any Claim involving third parties or to prosecute
     or defend such Claim to conclusion or settlement. If the Claims
     Representative makes the foregoing election, then the Claims Representative
     will take all necessary steps to contest any such Claim or to prosecute or
     defend such Claim to conclusion or settlement, and will notify Edge of the
     progress of any such Claim, will permit Edge, at its expense, to
     participate in such prosecution or defense (provided; however, that if a
                                                 --------  -------
     conflict of interest exists which would make it inappropriate, in the
     reasonable opinion of Edge, for the same counsel to represent both Edge and
     the Visionary Shareholders in the resolution of such Claim, then Edge may
     retain separate counsel, the fees and expenses of which shall not be borne
     by Edge but shall instead be borne by the Visionary Shareholders) and will
     provide Edge with reasonable access to all relevant information and
     documents relating to the Claim and the Claims Representative's prosecution
     or defense thereof. If the Claims Representative does not make such
     election, then Edge shall be free to handle the prosecution or defense of
     any such Claim, will take all necessary steps to contest any such Claim
     involving third parties or to prosecute or defend such Claim to conclusion
     or settlement, will notify the Claims Representative of the progress of any
     such Claim, and will permit the Claims Representative, at the expense of
     the Visionary Shareholders (which expense shall be paid for from sources
     other than the Withheld Merger Consideration), to participate in such
     prosecution or defense and will provide the Claims Representative with
     reasonable access to all relevant information and documents relating to the
     Claim and Edge's prosecution or defense thereof. In either case, the party
     not in control of a Claim will fully cooperate, and will cause its counsel,
     if any, to fully cooperate, with the other party in the conduct of the
     prosecution or defense of such Claim. Neither party will compromise or

     6.03 Edge Agreement to Indemnify.
          ---------------------------

          (a) Edge Indemnity. Subject to the limitations set forth in Section
              --------------
     6.03(b), Edge will indemnify and hold harmless the Visionary Shareholders
     (hereinafter in this Section 6.03 referred to individually as an "Edge
                                                                       ----
     Indemnified Person" and collectively as "Edge Indemnified Persons") from
     ------------------                       ------------------------
     and against any and all claims, demands, actions, causes of action, losses,
     costs, damages, liabilities and expenses including, without limitation,
     reasonable legal fees, net of any recoveries under insurance policies or
     tax savings known to any Visionary Shareholder at the time of making of
     claim hereunder, arising out of any misrepresentation or breach of or
     default in connection with any of the representations, warranties and
     covenants given or made by Edge in this Agreement or any certificate,
     document or instrument delivered by or on behalf of Edge pursuant hereto
     (hereafter in this Section 6.03 referred to as "Visionary Damages").
                                                     -----------------

          (b) Edge Indemnification Limitations. The indemnification provided for
              --------------------------------
     in Section 6.02(b) will not apply unless and until the aggregate Visionary
     Damages for which one or more Edge Indemnified Persons seeks
     indemnification under Section 6.03(a) exceeds $10,000 in which event the
     indemnification provided for in Section 6.03(a) will include all Visionary
     Damages in excess of such sum. The provisions of this Section 6.03 shall be
     the sole remedy against Edge for breach of Article IV.

          (c) Process. Promptly after the receipt by any Visionary Shareholder
              -------
     of notice or discovery of any claim, damage or legal action or proceeding
     giving rise to indemnification rights under this Section 6.03, such
     Visionary Shareholder will give Edge written notice of such claim, damage,
     legal action or proceeding (for purposes of this Section 6.03, a "Claim")
     in accordance with this Section 6.03. Within seven days of delivery of such
     written notice, Edge may, with such Visionary Shareholder's written
     consent, which shall not be unreasonably withheld, at the expense of Edge,
     elect to take all necessary steps properly to contest any Claim involving
     third parties or to prosecute or defend such Claim to conclusion or
     settlement. If Edge makes the foregoing election, then Edge will take all
     necessary steps to contest any such Claim or to prosecute or defend such
     Claim to conclusion or settlement, and will notify such Visionary
     Shareholder of the progress of any such Claim, will permit such Visionary
     Shareholder, at its expense, to participate in such prosecution or defense
     (PROVIDED, HOWEVER, that if a conflict of interest exists which would make
     it inappropriate, in the reasonable opinion of such Visionary Shareholder,
     for the same counsel to represent both such Visionary Shareholder and Edge
     in the resolution of such Claim, then such Visionary Shareholder may retain
     separate counsel, and the fees and expenses of one such counsel for all
     applicable Visionary Shareholders shall be borne by Edge rather than by any
     such Visionary Shareholder) and will provide such Visionary Shareholder
     with reasonable access to all relevant information and documents relating
     to the Claim and Edge's prosecution or defense thereof. If Edge does not
     make such election, then such Visionary Shareholder

AGREEMENT AND PLAN OF MERGER - Page 30

<PAGE>

     shall be free to handle the prosecution or defense of any such Claim, will
     take all necessary steps to contest any such Claim involving third parties
     or to prosecute or defend such Claim to conclusion or settlement, will
     notify Edge of the progress of any such Claim, and will permit Edge, at the
     expense of Edge, to participate in such prosecution or defense and will
     provide Edge with reasonable access to all relevant information and
     documents relating to the Claim and such Visionary Shareholder's
     prosecution or defense thereof. In either case, the party not in control of
     a Claim will fully cooperate with, and will cause its counsel, if any, to
     fully cooperate with, the other party in the conduct of the prosecution or
     defense of such Claim. Neither party will compromise or settle any such
     Claim without the written consent of either such Visionary Shareholder (if
     Edge defends the Claim) or Edge (if such Visionary Shareholder defends the
     Claim), such consent not to be unreasonably withheld. Notwithstanding the
     foregoing provisions of this Section 6.03(c), if two or more Visionary
     Shareholders deliver, whether separately or together, a Claim to Edge
     arising from or relating to the same or a reasonably similar matter, then
     the Claims Representative shall act on behalf of each such Visionary
     Shareholder bringing such a Claim for purposes of this Section 6.03.

                                  MISCELLANEOUS

     7.01 Governing Law; Specific Performance; Dispute Resolution. The laws of
          -------------------------------------------------------
the State of Texas (without regard to its choice of law principles that might
apply the law of another jurisdiction) will govern the validity of this
Agreement, the construction of its terms, and the interpretation and enforcement
of the rights and duties of the parties. Notwithstanding any other provision of
this Agreement, it is understood and agreed that the remedy of indemnity
payments and other remedies at law would be inadequate in the case of any breach
of the covenants contained herein and each party agrees that any other party
shall be entitled to equitable relief, including the remedy of specific
performance, without posting of bond or other security, with respect to any
breach or attempted breach of such covenants. Any dispute hereunder ("Dispute")
                                                                      -------
shall be settled by

AGREEMENT AND PLAN OF MERGER - Page 34

<PAGE>

arbitration in Dallas, Texas and, except as herein specifically stated, in
accordance with the commercial arbitration rules of the American Arbitration
Association ("AAA Rules") then in effect. However, in all events, these
              ---------
arbitration provisions shall govern over any conflicting rules that may now or
hereafter be contained in the AAA Rules. Any judgment upon the award rendered by
the arbitrator may be entered in any court having jurisdiction over the subject
matter thereof. The arbitrator shall have the authority to grant any equitable
and legal remedies that would be available in any judicial proceeding instituted
to resolve a Dispute.

          (a) Compensation of Arbitrator. Any such arbitration will be conducted
              --------------------------
     before a single arbitrator who will be compensated for his or her services
     at a rate to be determined by the parties or by the American Arbitration
     Association, but based upon a reasonable hourly or daily consulting rate
     for the arbitrator if the parties are not able to agree upon his or her
     rate of compensation.

          (b) Selection of Arbitrator. The American Arbitration Association will
              -----------------------
     have the authority to select an arbitrator from a list of arbitrators who
     are lawyers familiar with Texas contract law and experienced in mergers and
     acquisitions; provided, however, that such lawyers cannot work for a firm
     then performing services for either party, that each party will have the
     opportunity to make such reasonable objection to any of the arbitrators
     listed as such party may wish and that the American Arbitration Association
     will select the arbitrator from the list of arbitrators as to whom neither
     party makes any such objection. If the foregoing procedure is not followed,
     each party will choose one person from the list of arbitrators provided by
     the American Arbitration Association (provided that such person does not
     have a conflict of interest), and the two persons so selected will select
     from the list provided by the American Arbitration Association the person
     who will act as the arbitrator.

          (c) Payment of Costs. Edge and the Visionary Shareholders will each
              ----------------
     pay 50% of the initial compensation to be paid to the arbitrator in any
     such arbitration and 50% of the costs of transcripts and other normal and
     regular expenses of the arbitration proceedings; provided, however, that
     the prevailing party in any arbitration will be entitled to an award of
     attorneys' fees and costs, and all costs of arbitration, including those
     provided for above, will be paid by the non-prevailing party, and the
     arbitrator will be authorized to make such determinations.

          (d) Burden of Proof. For any Dispute submitted to arbitration, the
              ---------------
     burden of proof will be as it would be if the claim were litigated in a
     Texas judicial proceeding.

          (e) Award. Upon the conclusion of any arbitration proceedings
              -----
     hereunder, the arbitrator will render findings of fact and conclusions of
     law and a written opinion setting forth the basis and reasons for any
     decision reached and will deliver such documents to each party to this
     Agreement along with a signed copy of the award.

          (f) Terms of Arbitration. The arbitrator chosen in accordance with
              --------------------
     these provisions will not have the power to alter, amend or otherwise
     affect the terms of these arbitration provisions or the provisions of this
     Agreement.

          (g) Exclusive Remedy. Except as specifically otherwise provided in
              ----------------
     this Agreement, arbitration will be the sole and exclusive remedy of the
     parties for any Dispute arising out of this Agreement.

     7.02 Assignment; Binding Upon Successors and Assigns. No party may assign

any of its rights or obligations hereunder without the prior written consent of
the other party. This Agreement will be binding upon and inure to the benefit of
the parties and their respective successors and permitted assigns.

     7.03 Severability. If any provision of this Agreement, or the application
          ------------
thereof, is for any reason held to any extent to be invalid or unenforceable,
then the remainder of this Agreement and application of such provision to other
persons or circumstances will be interpreted so as reasonably to effect the
intent of the parties. The parties further agree to replace such unenforceable
provision of this Agreement with valid and enforceable provisions that will
achieve, to the extent possible, the economic, business and other purposes of
the invalid or unenforceable provisions.

     7.04 Counterparts. This Agreement may be executed in counterparts, each of
          ------------
which will be an original as regards any party whose signature appears thereon
and all of which together will constitute one and the same instrument. This
Agreement will become binding when one or more counterparts hereof, individually
or taken together, bear the signatures of all parties reflected hereon as
signatories. This Agreement may be executed by facsimile signature.

     7.05 Other Remedies. Except as otherwise provided herein, any and all
          --------------
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy will not preclude the exercise of any other.

     7.06 Amendment and Waivers. Any term or provision of this Agreement may be
          ---------------------
amended, and the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof or default in the performance hereof will
not be deemed to constitute a waiver of any other default of any succeeding
breach or default. This Agreement may be amended by the parties at any time.

     7.07 No Waiver. The failure of any party to enforce any of the provisions
          ---------
hereof will not be construed to be a waiver of the right of such party
thereafter to enforce such provisions. The waiver by any party of the right to
enforce any of the provisions hereof on any occasion will not be construed to be
a waiver of the right of such party to enforce such provisions on any other
occasion.

     7.08 Expenses. Unless otherwise provided in the Agreement, each party will
          --------
bear its respective expenses and fees of its own accountants, attorneys,
investment bankers and other professionals incurred with respect to this
Agreement and the transactions contemplated hereby; provided, however, that
Visionary will not incur, in connection with the Merger and the related
transactions contemplated hereby, expenses for fees and expenses of lawyers,
accountants and

other professionals in excess of $24,000 for the period of time from the
December 31,2001 until the Closing Date, unless any such fees or expenses are
paid by the Visionary Shareholders on or before the Closing Date.

     necessary to effect the terms and conditions of this Agreement, or as

               (iv)  Is being or has therefore been disclosed pursuant to a
                     valid court order after a reasonable attempt has been made

                     compiler.
