            hereby represents and warrants to the Company that:

            4.1   AUTHORIZATION. The Purchaser has full power and authority to
enter into this Agreement and this Agreement constitutes a valid and legally
binding obligation of the Purchaser, enforceable in accordance with its terms
except (i) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium, and other laws of general application affecting enforcement of
creditors' rights generally, and (ii) as limited by laws relating to the
availability of specific performance, injunctive relief or other equitable
remedies.

            4.2   PURCHASE ENTIRELY FOR OWN ACCOUNT. The Shares to be received
by the Purchaser and the Conversion Shares (collectively, the "SECURITIES") will
be acquired for investment for the Purchaser's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and the Purchaser has no present intention of selling, granting any
participation in or otherwise distributing the same except in compliance with
applicable federal and state securities laws. The Purchaser further represents
that the Purchaser does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer or grant participations to such
person or to any third person, with respect to any of

<PAGE>

                                                               EXECUTION VERSION

the Securities other than with respect to potential future distributions of the
Securities to its partners in compliance with applicable federal and state
securities laws.

            4.3   DISCLOSURE OF INFORMATION. The Purchaser has conducted its own
due diligence review of the Company and received copies or originals of all
documents it has requested from the Company. Notwithstanding the foregoing, this
representation shall not in any way be deemed to prohibit, limit, restrict or
otherwise impact the Purchaser's rights to indemnification, and/or to any other
rights or remedies available at law or equity, from the Company and its
affiliates in the event of a breach by the Company of any representation,
warranty, covenant or other term hereof or of any Related Recapitalization
Document.

            4.4   INVESTMENT EXPERIENCE. The Purchaser is an investor in
securities of companies in the development stage and acknowledges that it is
able to fend for itself, can bear the economic risk of its investment, including
a total loss, and has such knowledge and experience in financial or business
matters that it is capable of evaluating the merits and risks of the investment
in the Securities. The Purchaser also represents that it has not been organized
for the purpose of acquiring the Securities.

            4.5   ACCREDITED INVESTOR. The Purchaser is an "ACCREDITED INVESTOR"
within the meaning of Rule 501 of Regulation D promulgated under the Securities
Act.

            4.6   RESTRICTED SECURITIES. The Purchaser understands that the
issuance of the Securities has not been, and will not be, registered under the
Securities Act, by reason of a specific exemption from the registration
provisions of the Securities Act which depends upon, among other things, the
bona fide nature of the investment intent and the accuracy of the Purchaser's
representations as expressed herein. The Purchaser understands that the
Securities are characterized as "RESTRICTED SECURITIES" under applicable U.S.
federal and state securities laws and that, pursuant to these laws, Purchaser
must hold the Securities indefinitely unless subsequently registered for resale
with the Securities and Exchange Commission and qualified by state authorities,
or an exemption from such registration and qualification requirements is
available. Other than the registration rights set forth in the Convertible
Preferred Stock Term Sheet and the covenant set forth in Section 5.1 hereof, the
Purchaser acknowledges that the Company has no obligation to register or qualify
the Securities for resale.

            4.7   LEGENDS. It is understood that the certificates evidencing the
Securities may bear one or all of the following legends (or substantially
similar legends):

                  (a)   "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). THEY MAY NOT BE SOLD, OFFERED
FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION
STATEMENT AS TO SUCH SECURITIES UNDER THE ACT OR UNLESS SUCH TRANSACTION IS IN
COMPLIANCE WITH APPLICABLE FEDERAL AND STATE SECURITIES LAWS."

                  (b)   Any legend required by the laws of any state or foreign
jurisdiction, to the extent such laws are applicable to the shares represented
by the certificate so legended.

                  (c)   Any legend required by the Related Recapitalization

      5.    MISCELLANEOUS.

            5.1   REGISTRATION RIGHTS. The Company and the Purchaser agree that
they will each use their respective best efforts to promptly enter into an
Investors' Rights Agreement providing for the registration rights on the terms
set forth in the Convertible Preferred Stock Term Sheet at a mutually agreed
upon time in the future, which in any event shall be no later than ten business
days following the request by the Purchaser.

            5.2   TAX TREATMENT OF SHARES AND WARRANT. Each of the Company and
the Purchaser covenant that, if the Purchaser determines in its sole discretion
that doing so is appropriate, they will, as a result of arm's length bargaining,
agree on the fair market value of the Shares being issued in the Closing (if
issued apart from the Warrant), and the fair market value of the Warrant (if
issued apart from such Shares). The Company and the Purchaser further agree that
all tax filings and records relating to or including this Agreement, the Shares
and/or or the Warrant shall be prepared on the basis of, and consistently
reflect, the agreed fair market values determined in accordance with this
Section 5.2, and the Company shall instruct its accountants and other
tax-preparation professionals to prepare all tax filings and returns on such
basis.

            5.3   NO IMPAIRMENT. The Company shall not, by amendment of its
certificate of incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities, or any other
voluntary action, omission, or agreement, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed by the Company
under and/or in connection with this Agreement, but shall at all times in good
faith use best efforts to assist in carrying out of all the provisions of and/or
relating to this Agreement and in taking all such action as may be necessary or
appropriate to protect each Purchaser's rights, preferences and privileges under
and/or in connection with this Agreement against impairment.

            5.4   COUNTERPARTS. This Agreement may be executed in counterparts,
each of which when so executed and delivered will constitute a complete and
original instrument but all of which together will constitute one and the same
agreement, and it will not be necessary when making proof of this Agreement or
any counterpart thereof to account for any counterpart other than the
counterpart of the party against whom enforcement is sought.

            5.5   GOVERNING LAW. This Agreement will be governed by and
construed in accordance with the laws of the State of Delaware, without regard

personal jurisdiction and venue of such courts for the purposes thereof and
hereby irrevocably and unconditionally waives any claim (by way of motion, as a
