     2. BUYER'S REPRESENTATIONS AND WARRANTEES.
        --------------------------------------

         Each Buyer represents and warrants with respect to only itself that:

         a.  Investment Purpose.  Such Buyer (i) is acquiring the Debentures
             ------------------
     and, (ii) upon conversion of the Debentures will acquire the Conversion
     Shares then issuable, for its own account for investment only and not with
     a view towards, or for resale in connection with, the public sale or
     distribution thereof, except pursuant to sales registered or exempted under
     the 1933 Act; provided, however, that by making the representations herein,
     such Buyer does not agree to hold any Debentures or Conversion Shares for
     any minimum or other specific term and reserves the right to dispose of
     Debentures or Conversion Shares at any time in accordance with or pursuant
     to a registration statement or an exemption under the 1933 Act.

         b.  Accredited Investor/Tax Status.  Such Buyer is an "accredited
             ------------------------------
     investor" as that term is defined in Rule 501(a)(3) of Regulation D
     ("Regulation D") as promulgated by the United States Securities and
     Exchange Commission (the "SEC").  The Buyer is not subject to U.S.
     withholding tax or other similar state tax.

         c.  Reliance on Exemptions.  Such Buyer understands that the Debentures
             ----------------------
     and Conversion Shares are being offered and sold to it in reliance on
     specific exemptions from the registration requirements of United States
     federal and state securities laws and that the Company is relying in part
     upon the truth and accuracy of, and such Buyer's compliance with, the
     representations, warranties, agreements, acknowledgments and understandings
     of such Buyer set forth herein in order to determine the availability of
     such exemptions and the eligibility of such Buyer to acquire such
     securities.

         d.  Information.  Such Buyer and its advisors, if any, have been
             -----------
     furnished with all appropriate materials relating to the business, finances
     and operations of the

                                       2
<PAGE>

     Company and materials relating to the offer and sale of the Debentures and
     Conversion Shares which have been requested by such Buyer. Such Buyer and
     its advisors, if any, have been afforded the opportunity to ask questions
     of the Company. Neither such inquiries nor any other due diligence
     investigations conducted by such Buyer or its advisors, if any, or its
     representatives shall modify, amend or affect such Buyer's right to rely on
     the Company's representations and warranties contained in Section 3 below.
     Such Buyer understands that its investment in the Debentures and the
     Conversion Shares involves a high degree of risk. Such Buyer has sought
     such accounting, legal and tax advice as it has considered necessary to
     make an informed investment decision with respect to its acquisition of the
     Debentures and the Conversion Shares.

         e.  No Governmental Review.  Such Buyer understands that no United
             ----------------------
     States federal or state agency or any other government or governmental
     agency has passed on or made any recommendation or endorsement of the
     Debentures, the Conversion Shares, or the fairness or suitability of the
     investment in the Debentures and the Conversion Shares, nor have such
     authorities passed upon or endorsed the merits of the offering of the
     Debentures, and the Conversion Shares.

         f.  Transfer or Resale.  Such Buyer understands that except as
             ------------------
     provided in the Registration Rights Agreement: (i) the Debentures and the
     Conversion Shares have not been and are not being registered under the 1933
     Act or any state securities laws, and may not be offered for sale, sold,
     assigned or transferred unless such sale, assignment, or transfer is
     approved (unless to an affiliate or successor entity) by the Company and
     (a)  subsequently registered thereunder, (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, or (c) such Buyer provides the Company with
     reasonable assurance that such securities can be sold, assigned or
     transferred pursuant to Rule 144 promulgated under the 1933 Act (or a
     successor rule thereto); (ii) any sale of such securities made in reliance
     on Rule 144 promulgated under the 1933 Act (or a successor rule thereto)
     ("Rule 144") may be made only in accordance with the terms of Rule 144 and
     further, if Rule 144 is not applicable, any resale of such securities under
     circumstances in which the seller (or the person through whom the sale is
     made) may be deemed to be an underwriter (as that term is defined in the
     1933 Act) may require compliance with some other exemption under the 1933
     Act or the rules and regulations of the SEC thereunder; and (iii) neither
     the Company nor any other person is under any obligation to register such
     securities under the 1933 Act or any state securities laws or to comply
     with the terms and conditions of any exemption thereunder.

         g.  Legends.  Such Buyer understands that the certificates or other
             -------
     instruments representing the Debentures, until such time as the sale of the
     Conversion Shares have been registered under the 1933 Act as contemplated
     by the Registration Rights Agreement, the stock certificates representing
     the Conversion Shares shall bear a restrictive legend in substantially the
     following form (and a stop transfer order may be placed against transfer of
     such stock certificates):

                                       3
<PAGE>

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
     APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN
     ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE,
     SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE
     REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE
     SECURITIES LAWS, OR AN OPINION OF COUNSEL, IN A GENERALLY
     ACCEPTABLE FORM, THAT REGISTRATION IS NOT REQUIRED UNDER
     SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD
     PURSUANT TO RULE 144 UNDER SAID ACT.

The legend set forth above shall be removed and the Company shall issue a
certificate without such legend to the holder of the Debentures and the
Conversion Shares, upon which it is stamped, if, unless otherwise required by
applicable securities laws, (i) the sale of the Conversion Shares is registered
under the 1933 Act, (ii) in connection with a sale transaction, such holder
provides the Company with an opinion of counsel, reasonably satisfactory to the
Company, to the effect that a public sale, assignment or transfer of the
Debentures and the Conversion Shares may be made without registration under the
1933 Act, or (iii) such holder provides the Company with reasonable assurances
that the Debentures or the Conversion Shares can be sold pursuant to Rule 144
without any restriction as to the number of securities acquired as of a
particular date that can then be immediately sold.

     In addition to the foregoing, to the extent that the Holder receives a
certificate for Conversion Shares that does not contain the foregoing legend,
such holder understands that, (A) the Conversion Shares may be sold only by
means of a current prospectus or pursuant to an applicable exemption from
registration under the 1933 Act, (B) in connection with a prospectus sale, such
holder is required to deliver to the purchaser a current prospectus at the time
of resale of the Conversion Shares and (C) in that event, such holder is
responsible for determining that any such prospectus is current at the time of
resale. The Company undertakes to promptly notify the Holder in writing in the
event that facts and circumstances cause the prospectus to no longer be current
and shall indemnify and hold the Holder harmless from any costs, losses, or
damages, including reasonable attorney's fees that the Holder may suffer by
reason of the Company failing to provide such prompt notice. Holder hereby
indemnifies and holds the Company harmless from any costs, losses or damages,
including reasonable attorneys' fees, that the Company may suffer by reason of
holder's failure to comply with the provisions of this paragraph.

     governmental assessments and charges that are material in amount, shown or
     determined to be due on such returns, reports and declarations, except
     those being contested in good faith and has set aside on its books

<PAGE>

     Affiliates of the Company, including the Company's officers and directors,

     of the Company's Common Stock or hold a "put equivalent position" with
     respect to the Common Stock (as defined in Rule 16a-1 under the 1934 Act).
     Notwithstanding anything contained to the contrary in this section, in the
     event that the Company enters into a private placement transaction (other
     than in connection with employee benefit plans, employee or consultant
     compensation, or in connection with mergers and acquisitions) which permits
     the investors rights to engage in short sales of Common Stock, the
     restrictions contained in this section shall be automatically modified to
     permit the Buyer to engage in short sales of Common Stock substantially to
     the extent permitted by the Company with respect to such private placement
     investors.

     5.  TRANSFER AGENT INSTRUCTIONS.
         ---------------------------

          The Company shall issue irrevocable instructions to its transfer agent
to issue certificates, registered in the name of the Buyer or its respective
nominee(s), for the Conversion Shares in such amounts as specified from time to
time by the Buyer to the Company upon conversion of the Debentures (the
"Irrevocable Transfer Agent Instructions").  Prior to registration of the
Conversion Shares under the 1933 Act, all such certificates shall bear the
restrictive legend specified in Section 2(g) of this Agreement.  The Company
warrants that no instruction other than the Irrevocable Transfer Agent
Instructions referred to in this Section 5, and stop transfer instructions to
give effect to Section 2(f) hereof (in the case of the Conversion Shares, prior
to registration of such shares under the 1933 Act) will be given by the Company
to its transfer agent and that the Conversion Shares shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement or the Registration Rights Agreement.  Nothing in
this Section 5 shall affect in any way the Buyer's obligations and agreement to
comply with all applicable securities laws upon resale of the Debentures or the
Conversion Shares.  If the Buyer provides the Company with an opinion of
counsel, reasonably satisfactory in form, and substance to the Company, that
registration of a resale by the Buyer of any of the Debentures or the Conversion
Shares is not required under the 1933 Act, the Company shall permit the
transfer, and, in the case of the Conversion Shares, promptly instruct its
transfer agent to issue one or more certificates in such name and in such
denominations as specified by the Buyer.  The Company acknowledges that a breach
by it of its obligations hereunder will cause irreparable harm to the Buyer by
vitiating the intent and purpose of the transaction contemplated hereby.
Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Section 5 will be inadequate and agrees, in the event of
a breach or threatened breach by the Company of the provisions of this Section
5, that the Buyer shall be entitled, in addition to all other available
remedies, to an injunction

                                       13
<PAGE>

the necessity of showing economic loss and without any bond or other security
being required.

     action for which indemnification hereunder is sought), and including
     reasonable attorneys' fees and disbursements (the "Indemnified
     Liabilities"), incurred by the Indemnitees or any of them as a result of,
     or arising out of, or relating to (a) any misrepresentation or breach of
     any representation or warranty made by the Company in this Agreement, the
     Debentures or the Registration Rights Agreement or any other certificate,
     instrument or document contemplated hereby or thereby, (b) any breach of

     breach by that Buyer of (a) any misrepresentation or breach of any
     representation or warranty made by the Buyer in this Agreement, the
     Debentures or the Registration Rights Agreement or any other certificate,
