collectively referred to herein as the "Focus Parties"), RONALD GOLDBERG
("Goldberg"), PHILIP LEAVITT ("Leavitt"), SHERWIN GEITNER ("Geitner"), CARY
MAIMON ("Maimon") and MELVYN COHEN ("Cohen") (Goldberg, Leavitt, Geitner, Maimon
and Cohen individually a "CWI Stockholder" and collectively referred to herein
as the "CWI Stockholders"):


                                   WITNESSETH:

shareholders of Cellular Wholesalers, Inc. ("CWI") and, along with CWI, entered

July 23, 1999 with Focus and Merger Sub (the "Merger Agreement")(capitalized
terms not otherwise defined herein shall have the same meaning as in the Merger
Agreement); and

     WHEREAS, the parties to this Agreement desire to provide for the
contribution from Goldberg, Leavitt and Geitner (collectively, the "Contributing
CWI Stockholders") of certain Base Shares to the capital of Focus and to provide
for the closing of the escrow that was established pursuant to Section 1.8 of

pay Focus any other amounts based on the Closing Date Equity pursuant to Section
1.8 of the Merger Agreement, and the Principal CWI Stockholders shall not
receive any Additional Consideration pursuant to Section 1.7 of the Merger
Agreement, irrespective of the Closing Date Equity and the $500,000 reduction in

<PAGE>   3


whatsoever, known or unknown ("Focus Claim" or "Focus Claims"), which Focus or
Merger Sub now has, owns or holds, or may claim to have, own or hold, against
each or any of the CWI Releasees with respect to (i) the fairness of the
purchase price paid for CWI's assets under the Merger Agreement or this
Agreement and (ii) any of the representations or warranties made by CWI or any
of the CWI Stockholders in Sections 4.1(f) or 4.1(h) of the Merger Agreement or
any other provisions of the Merger Agreement that specifically relate to CWI's
stockholders equity, liquidity, profitability or financial condition or
prospects as of the Closing Date; provided, however, that such release shall not
extend to any other representations, warranties or covenants made by CWI or any

claims, liabilities, obligations, promises, agreements, controversies, damages,
costs, losses, debts and expenses (including, but not necessarily limited to,
reasonable attorney's fees and costs actually incurred), of any nature
whatsoever, known or unknown ("CWI Claim" or "CWI Claims"), which any of the CWI
Stockholders now has, owns, or holds, or may claim to have, own or hold, against
each or any of the Focus Releasees with respect to (i) the value of the common
stock of Focus or (ii) any of the representations or warranties made by Focus

     5.3 EFFECT OF RELEASE. Each of the parties to this Agreement acknowledges
that such party may hereafter discover claims or facts in addition to or
different from those which such party now knows or believes to be true with
respect to the matters released herein, but that it is the intention of each of
the parties to this Agreement to fully, finally, and forever settle and release

have existed. In furtherance of such intention, the releases set forth in this

<PAGE>   4


complete releases regardless of the existence or discovery of any such
additional or different claims or facts.

          5.4 NO ASSIGNMENT OF CLAIMS. Each of the parties to this Agreement
represents that such party has not heretofore assigned or transferred, or
purported to assign or transfer, to any person or entity, any CWI Claim or Focus
Claim, as applicable, or any portion thereof or interest therein.

     6. COVENANT NOT TO SUE BY THE FOCUS PARTIES. Each of the Focus Parties
hereby agrees not to sue any CWI Releasee(s) relating to any causes of action
that might be alleged to exist at the present time under California Civil Code
Sections 3439 through 3439.12, inclusive, or any state laws similar thereto. All
parties to this Agreement agree that the following facts are true, and that the
provisions of this Section 6 shall permanently survive the Closing, and, to the
extent allowed by law, be binding upon all of the parties and their successors
in interest:

          (a) No transfer at any time under the Merger Agreement or any other
agreement to any of the CWI Stockholders by any of the Focus Parties of any
assets, including, but without limitation, money or tangible or intangible
personal property, was made by the transferor without the transferor having
received full or reasonably equivalent value in exchange or in consideration for
said transfer.

          (b) Any and all transfers to any of the CWI Stockholders by any of the
Focus Parties of any assets, including, but without limitation, money or
tangible or intangible personal property, were received by the transferees
thereof, including any of the CWI Releasees, in good faith and for a reasonably
equivalent value.

     The covenant not to sue and agreed statement of facts contained in this
Section 6 shall in no way limit the rights of the Focus Parties to seek or
obtain indemnification pursuant to Article VIII of the Merger Agreement for the
breach by CWI or any of the CWI Stockholders of any representation, warranty or
covenant contained in the Merger Agreement (except as otherwise specifically
limited by Section 5.1 of this Agreement).

     7. INDEMNIFICATION OF THE CWI RELEASEES BY THE FOCUS PARTIES. The Focus
Parties hereby agree to indemnify, save, defend and hold harmless each of the
CWI Releasees from and against any cost or expense (including reasonable
attorneys fees and costs) in defending against any suit or other claim brought
by any creditor of Focus or Merger Sub that alleges that the transactions
consummated pursuant to the Merger Agreement and/or this Agreement constituted a
fraudulent conveyance as against such creditor; provided, however, that the
foregoing indemnification shall not extend to any settlements of the foregoing
claims or judgments entered against any of the CWI


                                      -4-
<PAGE>   5


Releasees based on the foregoing claims, which shall be the sole responsibility
of the CWI Releasees. A claim for indemnification hereunder (an "Indemnification
Claim") shall be made by the CWI Releasees by delivery of a written notice to
the Focus Parties requesting indemnification and specifying the basis on which
indemnification is sought in reasonable detail (and shall include relevant
documentation related to the Indemnification Claim), and such other information
as the CWI Releasees shall have concerning such claim.

     Should any claim be made or any suit or proceeding instituted by a third
party against any of the CWI Releasees which would be a matter for which the CWI
Releasees would be entitled to indemnification under this Section 7 (a "Third
Party Claim"), the obligations and liabilities of the parties hereunder with
respect to such Third Party Claim shall be subject to the following terms and
conditions:

          7.1 The CWI Releasees shall give the Focus Parties written notice of
any Third Party Claim promptly (and in no event later than 10 days) after
receipt by the CWI Releasees of notice thereof, and the Focus Parties will
undertake control of the defense thereof at the Focus Parties' cost and expense
by counsel of their own choosing reasonably acceptable to the CWI Releasees. The
CWI Releasees may participate in the defense through their own counsel at their
own expense. If the Focus Parties fail or refuse to undertake the defense of
such Third Party Claim within 15 days after written notice of such claim has
been delivered to the Focus Parties by the CWI Releasees, the CWI Releasees
shall have the right to undertake the defense of such Third Party Claim with
counsel of their own choosing. Failure of the CWI Releasees to furnish written
notice to the Focus Parties of a Third Party Claim shall not release Focus
Parties from the Focus Parties's obligations hereunder, except to the extent the
Focus Parties are prejudiced by such failure.

          7.2 The CWI Releasees and the Focus Parties shall cooperate with each
other in all reasonable respects in connection with the defense of any Third
Party Claim, including making available records relating to such claim and
furnishing employees of the CWI Releasees as may be reasonably necessary for the
preparation of the defense of any such Third Party Claim or for testimony as
witnesses in any proceeding relating to such claim. The CWI Releasees may settle
any Third Party Claim without the consent of Focus Parties, provided that such
settlement does not require any payment by or impose any obligation upon the
Focus Parties. The Focus Parties shall not settle any Third Party Claim without
the consent of the CWI Releasees unless they undertake payment responsibility
for such claim.
