or properties is bound by or subject to) any written or oral, express or

     2.27.  Customer Relations.
            ------------------

     The Company has received no customer complaints concerning its products,
nor has it had its products returned by a purchaser thereof or had any claims

has caused or could reasonably be expected to cause, individually or in the
aggregate, a Material Adverse Effect.

3.   Representations and Warranties of the Investor.
     ----------------------------------------------

     The Investor hereby represents and warrants to the Company that:

     3.1.   Authorization.
            -------------

     Subject to the approval of the Investor's Board of Directors, the Investor
has full power and authority to enter into this Agreement and the Investor
Rights Agreement, and, upon such approval, each such agreement will constitute
the Investor's valid and legally binding obligation, 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, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief or other equitable
remedies, and (iii) to the extent the

                                       20
<PAGE>

indemnification provisions contained in the Investor Rights Agreement may be
limited by applicable federal or state securities laws.

     3.2.   Purchase Entirely for Own Account.
            ---------------------------------

     The Purchased Shares will be acquired for investment for the Investor'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 Investor has no present intention of
selling, granting any participation in or otherwise distributing any of the
Purchased Shares.

     3.3.   Disclosure of Information.
            -------------------------

     The Investor 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 the business, properties, prospects and financial condition
of the Company; provided, however, that this Section 3.3 does not limit or
                --------  -------
modify in any way the representations and warranties of the Company contained in
this Agreement, the Investor Rights Agreement or in any other agreement or
document delivered by the Company pursuant hereto or thereto or the right of the
Investor to rely thereon.

     3.4.   Restricted Securities.
            ---------------------

     The Investor acknowledges that the Purchased Shares are "restricted
securities" under the Securities Act and state securities laws inasmuch as they
are being acquired from the Company in a transaction not involving a public
offering and that under such laws and applicable regulations promulgated
pursuant thereto, the Purchased Shares may be resold without registration under
the Act only in certain limited circumstances. In the absence of an effective
registration statement covering the Purchased Shares (or the Conversion Shares)
or an exemption from registration under the Act, the Purchased Shares (and the
Conversion Shares) must be held indefinitely. 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 acknowledges
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

                                       21
<PAGE>

Shares. The Investor is an "Accredited Investor" as that term is defined in
Section 501(a) of Regulation D, promulgated under the Securities Act.

     3.5.   Legends.
            -------

     The Investor acknowledges that the certificates evidencing the Purchased
Shares and the Conversion Shares will bear the following legends:

            "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
            REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
            (THE "ACT"), OR UNDER 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
            APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
            REGISTRATION OR EXEMPTION THEREFROM."

The legend set forth 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 1933 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.

4.   Conditions of Investor's Obligations at Closing.

     The obligations of the Investor to consummate the transactions contemplated

is to be made by a person entitled to indemnification hereunder, the person

of such lawsuit or other legal action in accordance with this Section 6.2, the
Indemnified Party may, at its own cost and expense, participate in the
investigation, trial and defense of such Third-Party Claim. If the Indemnifying
Party fails to assume the defense of such Third-Party Claim in accordance with
this Section within 30 calendar days after receipt of the Claim Notice, the
Indemnified Party against which such Third-Party Claim has been asserted shall
(upon delivering notice to such effect to the Indemnifying Party) have the right
to undertake, at the Indemnifying Party's cost, risk and expense, the defense,
compromise and settlement of such Third-Party Claim on behalf of and for the
account of the Indemnifying Party; provided that such Third-Party Claim shall
not be compromised or settled without the written consent of the Indemnifying
Party, which consent shall not be unreasonably withheld. In the event the
Indemnifying Party assumes the defense of the claim, the Indemnifying Party
shall keep the Indemnified Party reasonably informed of the progress of such
defense, compromise or settlement, and in the event the Indemnified Party
assumes the defense of the claim, the Indemnified Party shall keep the
Indemnifying Party reasonably informed of the progress of any such defense,
compromise or settlement. The Indemnifying Party shall be liable for any
settlement of any Third-Party Claim effected pursuant to and in accordance with
this Section 6 and for any final judgment (subject to any right of appeal), and
the Indemnifying Party agrees to indemnify and hold harmless each Indemnified
Party from and against any and all Losses incurred by the Indemnified Party by
reason of such settlement or judgment.
