the registration requirements of United States federal and state securities laws
and that the Seller and the Company are relying upon the truth and accuracy of,

transferred unless (A) subsequently registered thereunder or (B) such Buyer
shall have delivered to the Company an opinion of counsel, in a generally
acceptable form, to the effect that such securities to be sold, assigned or
transferred may be sold, assigned or transferred pursuant to an exemption from
such registration requirements; (ii) any sale of such securities made in
reliance on Rule 144 under the Act (or a successor or rule thereto) ("RULE 144")
may be made only in accordance with the terms of Rule 144; (iii) except as set
forth in Section 6.3 hereof, neither the Company nor any other person is under
any obligation to register such securities under the Act or any state securities
laws or to comply with the terms and conditions of any exemption thereunder; and

The Company may place stop transfer instructions against the certificates for
the Shares.

parties, the indemnifying party shall be entitled to assume control of the
defense of such action or claim with counsel reasonably satisfactory to the
indemnified party; PROVIDED, HOWEVER, that: (a) the indemnified party shall be
entitled to participate in the defense of such claim and to employ counsel at
its own expense to assist in the handling of such claim; (b) the indemnifying
party shall not consent to the entry of any judgment or enter into any
settlement that does not include as an unconditional term thereof the giving by
each claimant or plaintiff to the indemnified party a release from all liability
in respect of such claim if, pursuant to or as a result of such consent or
settlement, injunctive or other equitable relief would be imposed against the
indemnified party or such judgment or settlement would materially interfere with
the business, operations or assets of the indemnified party; and (c) if the
indemnifying party does not assume control of the defense of such claim in
accordance with the foregoing provisions within 15 days after receipt of notice
of the claim, the indemnified party shall have the right to defend such claim in
good faith in such manner as it may deem appropriate at the reasonable cost and
expense of the indemnifying party, and the indemnifying party will promptly
reimburse the indemnified party for such cost and expense.

         Section 5.3 LIMITATIONS ON RIGHTS TO INDEMNIFICATION. The obligations
to indemnify pursuant to this Article V are subject to the following
limitations:

                  (a) A party seeking indemnification hereunder shall not be
entitled to recover for Buyer Damages or Seller/Company Damages, as the case may
be, incurred by it unless a claim for such Buyer Damages or Seller/Company
Damages, as the case may be, has been asserted by prompt written notice,
specifying the details of the alleged claim, and delivered to the indemnifying
parties.

                  (b) The indemnification obligation of an indemnifying party in
this Article V shall not be affected by the failure of the indemnified party to
give notice in accordance herewith unless the indemnifying party is actually
prejudiced thereby, in which case the indemnifying party's liability shall be
reduced by and to the extent of any actual prejudice.

                  (c) Notwithstanding anything else to the contrary in this
Section, the parties acknowledge and agree that: (i) the indemnification
provisions in this Article V are the

                                       14
<PAGE>

exclusive remedy for the (1) Buyers for any breach of representations,
warranties and/or covenants by the Seller or the Company in this Agreement,
except in the case of intentional fraud and (2) Seller and the Company for any
breach of representations, warranties and/or covenants by either Buyer in this
Agreement, except in the case of intentional fraud; and (ii) the Seller and/or
the Company, in the aggregate, shall not be liable to the indemnified parties
for Buyer Damages to the extent such Damages exceed the Purchase Price paid to
the Seller pursuant to SECTION 2.2, other than in the case of intentional fraud
(which shall not be subject to any such limit).

                  (d) Notwithstanding anything else to the contrary in this
Agreement, no claim by an indemnified party for indemnification hereunder may be
made unless and until such time as all claims for indemnification hereunder by
such party shall exceed $50,000, after which the total amount of all claims,
including such $50,000, shall be recoverable.

                  (e) The aggregate amount of Buyer Damages recoverable by the
Buyers shall not exceed the lesser of (x) the direct Buyer Damages actually
incurred by the Buyers and (y) any diminution in the fair value of the Shares
resulting from breach(es) hereunder; provided that such later resulting fair
value of the Shares shall be determined by an independent third-party approved
by the Company and the Buyers.

                  (f) The Buyers hereby acknowledge and agree that their only
recourse for any breaches of the representations and warranties contained in
Section 3.2 hereof shall be against the Seller (and not the Company).

         Section 5.4 SURVIVAL. All covenants and agreements of each party set
forth herein requiring performance after the Closing shall survive the Closing
and shall remain in effect in accordance with their respective terms until
performed or waived. Further, all representations and warranties contained in
this Agreement (including the Disclosure Schedule) and the Buyers' right to
indemnification hereunder, shall survive the Closing and shall remain in effect
for a period of fifteen (15) months after the Closing Date, and not thereafter;
PROVIDED, HOWEVER, claims under SECTION 3.2 shall survive for the shorter of (i)
the period of time that the applicable statute of limitations relating to any
claim or cause of action resulting from the breach of the representation or
warranty contained in such Section applies or (ii) two (2) years, except, in any
case, with respect to intentional fraud.

                                   ARTICLE VI
                                  MISCELLANEOUS

         Section 6.1 BOARD RIGHTS. Subject to any reasonably required
restrictions on the use or disclosure of confidential information with respect
to corporate opportunities or otherwise, for a period of one year from the date
hereof (the "INITIAL BOARD RIGHT PERIOD"), the Company shall permit the Buyers,
and the Buyers shall have the right, to have one representative of the Buyers
attend and observe all meetings of the Company's Board of Directors (the "BOARD
RIGHTS"). Such representative will have no voting rights or other
responsibilities or rights related to the management or oversight of the
Company, but shall receive the same notice of meetings of the Company's Board of
Directors as required by the Company bylaws or as is otherwise provided to the
Company's Board of Directors by the Company. The parties hereby agree to discuss
in

                                       15
<PAGE>

good faith prior to the end of the Initial Board Right Period (i) the business
collaboration achievements of the Company and the Buyers, and (ii) the extension
of the Board Rights provided to the Buyers under this Section 6.1 for an
additional period beyond the Initial Board Right Period.

         Section 6.2 INFORMATION RIGHTS. For so long as the Buyers shall hold
any of the Shares, or until the Company effects an initial public offering of
its Common Stock (an "IPO"), the Buyers shall have the right to receive, and the
Company shall provide to the Buyers, (i) unaudited monthly and quarterly
financial statements (including, without limitation, income statements, balance
sheets, and cash flow statements) and management commentary within thirty (30)
days of the close of each respective month and forty five (45) days after the
end of each quarter, (ii) audited financial statements (including, without
limitation, income statements, balance sheets, and cash flow statements) within
ninety (90) days of the close of the fiscal year, and (iii) annual budgets.
After an IPO, the Buyers shall be entitled to receive such information as is
made available by the Company to the public.

         Section 6.3 REGISTRATION RIGHTS. In the event that the Company shall
effect a registration of any of its Common Stock on behalf of the Seller for the
resale of such Common Stock to the public, other than a registration in
connection with the IPO, including a registration pursuant to the terms of any
over-allotment or "green shoe" option, subject to the restrictions set forth
below, the Buyers shall be entitled to include the Shares, proportionally with
any shares of Common Stock being registered on behalf of the Seller, in any such
registration statement proposed to be filed by the Company with the Securities
and Exchange Commission. If the managing underwriter advises the Company that
inclusion of the Seller's shares or the Buyer's Shares proposed to be included
in such registration would interfere with the successful marketing (including
pricing) of the offering, then the number of shares proposed to be included in
such offering shall be included in the following order:

                  (a) first, any securities held by the parties to the Company
Stockholder's Agreement, except the Seller or David Peterson, whether Common
Stock, Preferred Stock or Common Stock issued or to be issued upon the
conversion of Preferred Stock or convertible notes into Common Stock;

                  (b) second, the Buyers' Shares and Seller's shares; and

                  (c) third, all other selling shareholders' shares which have
registrations rights or are otherwise being registered.

         Section 6.4 THIRD-PARTY SALE RIGHTS. In the event the Seller ceases to
be the majority shareholder of the Company (or would cease to be the majority
shareholder of the Company as a result of any sale or other transfer of Seller's
Common Stock or other equity interests in the Company), or after the earlier of
(a) the consummation of an IPO, or (b) August __, 2005, if the Seller proposes
to sell or otherwise transfer Common Stock or other equity interests in the
Company held by such Seller to any third party in a private transaction, the
Seller shall provide the Buyers with (i) notice of such intention to sell or
transfer such interests in the Company, and shall negotiate with the Buyers with
respect to Buyers' desire, if any, to purchase such Common Stock or other equity
interests in the Company from the Seller, and (ii) the right, at the Buyers'

                                       16
<PAGE>

election, to sell a proportionate amount of Buyers' Shares on the same terms
offered to the Seller by any proposed third-party transferee. In the event that
(i) any proposed third-party transferee refuses to purchase such proportionate
number of the Shares from the Buyers, and (ii) the Seller sells any of his
shares to such third-party transferee, then the Seller shall purchase such
proportionate number of the Shares from the Buyers on the same terms offered to
the Seller by the Third-party transferee. The provisions of this Section 6.4
shall not in any way prevent the Seller from selling his shares to a third party
subject to the notice requirements contained herein.

         Section 6.5 PROHIBITION AGAINST TRANSFER TO AN INDUSTRY PARTICIPANT
PRIOR TO IPO. The Buyers covenant and agree that prior to an IPO they shall not
sell, transfer, gift, pledge, assign, distribute, encumber, hypothecate,
mortgage or grant a security interest or lien or other disposition, to any
natural person, corporation, limited partnership, general partnership, limited
liability company or partnership, joint stock company, joint venture,
association, company, trust, bank, trust company, land trust, business trust or
other organization, whether or not legal entities or governments or agencies or
other administrative or regulatory thereof that is engaged in the business in
which the Company and/or its subsidiaries or affiliates are engaged in as of the
later of the date hereof or the date the Company delivers either quarterly or
annual financial statements pursuant to Section 6.2 hereof (an "Industry
Participant").

         Section 6.6 LOCK-UP REQUIRED BY UNDERWRITERS IN IPO. The Buyers agree
that they will execute any "Lock-Up" Agreement required by the managing
underwriters in the IPO which lock-up will be the same as required of the
Seller.

         Section 6.7 NOTICES. All notices, requests, demands and other
communications provided for hereunder shall be in writing and directed to each
applicable party at the address set forth hereafter or at such other address as
to which such party may inform the other parties in writing in compliance with
