conducted and as presently proposed to be conducted, without any conflict with
or infringement of the rights of others. A complete list of all the Company's
Proprietary Assets is set forth on Schedule 3.9(a) to this Agreement. To the

judgment, decree or order of any court or administrative agency, or any other
restriction that would interfere with the use of his or her best efforts to
carry out his or her duties for the Company or to promote the interests of the
Company or that would conflict with the Company's business as proposed to be
conducted. The carrying on of the Company's business by the employees and
contractors of the Company and the conduct of the Company business as presently
proposed, will not, to the best of the Company's Knowledge, conflict with or
result in a breach of the terms, conditions or provisions of, or constitute a
default under, any contract, covenant or instrument under which any of such
employees or contractors or the Company is now obligated. The Company does not

INVESTOR. The Investor hereby represents and warrants to, and agree with, the
Company that:


                  4.1 Authorization. This Agreement constitutes the Investor's
valid and legally binding obligation, enforceable in accordance with its terms
except as may be limited by (i) applicable bankruptcy, insolvency,
reorganization or other laws of general application relating to or affecting the
enforcement of creditors' rights generally and (ii) the effect of rules of law
governing the availability of equitable remedies. The Investor represents that
it has full power and authority to enter into this Agreement and the Related
Agreements.

                  4.2 Purchase for Own Account. The Purchased Shares to be
purchased by the Investor hereunder will be acquired for investment for the
Investor's own account, not as a nominee or agent, and not with a view to the
public resale or distribution thereof within the meaning of the Act, and the
Investor has no present intention of selling, granting any participation in, or
otherwise distributing the same. The Investor also represents that it has not
been formed for the specific purpose of acquiring the Purchased Shares.


                                       13

<PAGE>




                  4.3 Disclosure of Information. The Investor has received or
has had full access to all the information it considers necessary or appropriate
to make an informed investment decision with respect to the Purchased Shares to
be purchased by the Investor under this Agreement. The Investor further has had
an opportunity to ask questions and receive answers from the Company regarding
the terms and conditions of the offering of the Purchased Shares and to obtain
additional information (to the extent the Company possessed such information or
could acquire it without unreasonable effort or expense) necessary to verify any
information furnished to the Investor or to which the Investor had access. The
foregoing, however, does not in any way limit or modify the representations and
warranties made by the Company in Section 3.

                  4.4 Accredited Investor Status. The Investor is an "accredited
investor" within the meaning of Regulation D promulgated under the Act.

                  4.5 Investment Experience. The Investor understands that the
acquisition of the Purchased Shares involves substantial risk. The Investor: (i)
has experience as 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 acquisition of the Purchased Shares and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits and risks of this acquisition of the Purchased Shares and protecting its
own interests in connection with this acquisition and/or (ii) has a preexisting
personal or business relationship with the Company and certain of its officers,
directors or controlling persons of a nature and duration that enables the
Investor to be aware of the character, business acumen and financial
circumstances of such persons.

                  4.6 Restricted Securities. The Investor understands that the
Purchased Shares are characterized as "restricted securities" under the Act
inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under the Act and applicable rules and
regulations thereunder such securities may be resold without registration under
the Act only in certain limited circumstances. In this connection, the Investor
represents that it is familiar with Rule 144 of the rules and regulations
promulgated under the Act ("Rule 144"), as presently in effect, and understands
the resale limitations imposed thereby and by the Act. The Investor understands
that the Company is under no obligation to register any of the securities sold
hereunder except as provided in the Investor Rights Agreement. The Investor
understands that no public market now exists for any of the Purchased Shares and
that it is uncertain whether a public market will ever exist for the Purchased
Shares or the Conversion Shares.

                  4.7 Further Limitations on Disposition. Without in any way
limiting the representations set forth above, the Investor further agrees not to
make any disposition of all or any portion of the Purchased Shares or the
Conversion Shares unless and until:

                           (a) there is then in effect a registration statement
under the 1933 Act covering such proposed disposition and such disposition is
made in accordance with such registration statement; or


                                       14

<PAGE>



                           (b) (i) the Investor shall have notified the Company
of the proposed disposition and shall have furnished the Company with a
statement of the circumstances surrounding the proposed disposition, and (ii)
the Investor shall have furnished the Company, at the expense of the Investor or
its transferees, with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such securities
under the Act.

                  Notwithstanding the provisions of paragraphs (a) and (b)
above, no such registration statement or opinion of counsel shall be required:
(i) for any transfer of any Purchased Shares or Conversion Shares in compliance
with Rule 144 or Rule 144A; or (ii) for any transfer of any Purchased Shares or
Conversion Shares by the Investor to (A) a partner or member of such Investor,
(B) a retired partner of such Investor who retires after the date hereof, or (C)
the estate of any such partner or member; provided that in each of the foregoing
cases the transferee agrees in writing to be subject to the terms of this
Section 4 (other than Section 4.4) to the same extent as if the transferee were
an original Investor hereunder.

                  4.8 Legends. It is understood that the certificates evidencing
the Purchased Shares and the Conversion Shares will bear the legends set forth
below:

                           (a) THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN

THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS
ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS
PERMITTED UNDER THE ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD
OF TIME. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN
FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED
TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE
SECURITIES LAWS.

                           (b) Any legend required by state securities laws,
including a legend substantially in the form of the following:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE:  (1) ARE
         CONVERTIBLE INTO SHARES OF COMMON STOCK OF THE COMPANY AT
         THE OPTION OF THE HOLDER AT ANY TIME PRIOR TO AUTOMATIC
         CONVERSION THEREOF; AND (2) AUTOMATICALLY CONVERT INTO
         COMMON STOCK OF THE COMPANY IN THE EVENT OF A PUBLIC
         OFFERING MEETING CERTAIN REQUIREMENTS OR UPON CERTAIN
         CONSENTS OF THE HOLDERS OF THE COMPANY'S PREFERRED STOCK
         ALL PURSUANT TO AND UPON THE TERMS AND CONDITIONS SPECIFIED
         IN THE COMPANY'S CERTIFICATE OF DESIGNATION.  A COPY OF SUCH

<PAGE>





         The legend set forth in (a) above shall be removed by the Company from
any certificate evidencing Purchased Shares or Conversion Shares upon delivery
to the Company of an opinion by counsel, reasonably satisfactory to the Company,
that a registration statement under the Act is at that time in effect with
respect to the legended security or that such security can be freely transferred
in a public sale without such a registration statement being in effect and that
such transfer will not jeopardize the exemption or exemptions from registration
pursuant to which the Company issued the Purchased Shares or Conversion Shares.
