fee, brokerage commission or similar payment.


                                     III.

               REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

          Each Purchaser, severally and not jointly, represents and warrants to
the Company and to the other Purchasers as follows:

          SECTION 3.01.  Authorization.  The execution, delivery and performance
                         -------------
by such Purchaser of this Agreement, and the purchase and receipt by such
Purchaser of the Securities being acquired by it hereunder, have been duly
authorized by all requisite action on the part of such Purchaser, and will not
(x) violate any provision of law, any order of any court or other agency of
government, the charter or other governing documents of such Purchaser, or any
provision of any indenture, agreement or other instrument by which such
Purchaser or any of such Purchaser's properties or assets are bound; (y)
conflict with, result in a breach of or constitute (with due notice or lapse of
time or both) a default under any such indenture,

                                       3
<PAGE>

agreement or other instrument; or (z) result in any Claim upon any of the
properties or assets of such Purchaser.

          SECTION 3.02.  Validity.  This Agreement has been duly executed and
                         --------
delivered by such Purchaser and constitutes the legal, valid and binding
obligation of such Purchaser, enforceable against such Purchaser in accordance
with its terms.

          SECTION 3.03.  Investment Representations.  For purposes of this
                         --------------------------
Section 3.03, the term "such Purchaser" shall be deemed to include such
Purchaser and its partners, in the case of a Purchaser that is a limited
partnership that has been formed solely for the purpose of purchasing the
Securities.

          (a)  Such Purchaser is acquiring the Securities being purchased by
such Purchaser hereunder for such Purchaser's own account, for investment, and
not with a view toward the resale or distribution thereof.

          (b)  Such Purchaser understands that he, she or it, as the case may
be, must bear the economic risk of such Purchaser's investment for an indefinite
period of time because the Securities are not registered under the Securities
Act of 1933, as amended (the "Securities Act"), or any applicable state
securities laws, and may not be resold unless subsequently registered under the
Securities Act and such other laws or unless an exemption from such registration
is available. Such Purchaser also understands that, except as provided in the
Registration Rights Agreement (the "Registration Rights Agreement"), dated as of
July 22, 1999, among the Company and the other parties signatory thereto, it is
not contemplated that any registration will be made under the Securities Act or
that the Company will take steps which will make the provisions of Rule 144
under the Securities Act available to permit resale of the Securities. Such
Purchaser agrees not to pledge, transfer, convey or otherwise dispose of any of
the Securities (including any shares of Common Stock into which the Securities
are convertible), except in a transaction that (A) is permitted under the
Stockholders Agreement and (B) is the subject of either (i) an effective
registration statement under the Securities Act and any applicable state
securities laws, or (ii) an applicable exemption from the Securities Act and any
applicable state securities laws as confirmed, if reasonably requested by the
Company, by an opinion of counsel to the effect that such registration is not
required (which opinion and counsel shall be reasonably satisfactory to the
Company), it being intended that the agreements with respect to the Securities
contained in this sentence shall be construed consistently with the provisions
relating to the same subject matter contained in the Registration Rights
Agreement (provided that the provisions of the Registration Rights Agreement
shall govern in the event of any conflict with the terms of this sentence).

          (c)  Such Purchaser has the ability to bear the economic risks of the
investment in the Securities being purchased hereunder for an indefinite period
of time.  Such Purchaser further acknowledges that he, she or it, as the case
may be, has had the opportunity to ask questions of, and receive answers from,
officers of the Company with respect to the business and financial condition of
the Company and the terms and conditions of the offering of the Securities and
to obtain additional information necessary to verify such information or can
acquire it without unreasonable effort or expense.

                                       4
<PAGE>

          (d)  Such Purchaser has such knowledge and experience in financial and
business matters that such Purchaser is capable of evaluating the merits and
risks of its investment in the Securities.  Such Purchaser further represents
that he, she or it, as the case may be, is an "accredited investor" as such term
is defined in Rule 501 of Regulation D under the Securities Act with respect to
its purchase of the Securities.

          (e)  If such Purchaser is a limited partnership or limited liability
company, such Purchaser represents that it has been organized and is existing as
a limited partnership or limited liability company under the laws of its
jurisdiction of organization.

          SECTION 3.04.  Governmental Approvals.  No registration or filing
                         ----------------------
with, or consent or approval of, or other action by, any Federal, state or other
governmental agency or instrumentality is or will be necessary by any Purchaser
for the valid execution, delivery and performance of this Agreement.

          SECTION 3.05.  Brokers.  All negotiations relative to this Agreement
                         -------
and the transactions contemplated hereby have been carried on by such Purchaser
without the intervention of any person on behalf of such Purchaser in such
manner as to give rise to any valid claim by such person against the Company or
the other Purchasers for a finder's fee, brokerage commission or similar
payment.


                                      IV.

                                   COVENANTS

          SECTION 4.01.  Conduct of the Company's Business.  The Company agrees
                         ---------------------------------
that, between the date hereof and the Closing Date, it shall not (i) issue,
sell, pledge or dispose of, or agree to issue, sell, pledge or dispose of, any
shares of, or securities convertible or exchangeable for, or any options,
warrants or rights of any kind to acquire any shares of, its capital stock of
any class, except as provided herein; (ii) acquire (by merger, consolidation or
acquisition of stock or assets) any corporation, partnership or other business
organization or division thereof (except an existing wholly-owned subsidiary) or
any material amount of assets; (iii) incur or guarantee any indebtedness for
borrowed money or refinance any such indebtedness or issue or sell any debt
securities; (iv) enter into or modify any material contract, lease, agreement or
commitment, or permit or perform any act that would cause a material breach of
any such contract, lease, agreement or commitment; (v) make any loans, advances
or capital contributions to or investments in, any other person; or (vi) violate
or fail to perform in any material respect any obligation imposed upon the
Company or any of its subsidiaries by any applicable laws, orders, decrees,
ordinances, government rules or regulations.

          SECTION 4.02.  Further Assurances.  Subject to the terms and
                         ------------------
conditions herein provided, each of the parties hereto agrees to use its
reasonable best efforts to take, or cause to be taken, all action and to do, or
cause to be done, all things necessary, proper or advisable to consummate and
make effective as promptly as practicable the transactions contemplated by this

                                       5
<PAGE>

Agreement, including, without limitation, using all reasonable efforts to obtain
all necessary waivers, consents and approvals and to effect all necessary
registrations and filings.  Without limiting the foregoing, between the date
hereof and the Closing Date the Company shall take such actions as may be
necessary to increase its authorized but unissued capital stock to allow it to
issue the Warrant.


                                      V.

                             CONDITIONS PRECEDENT
