                        ---------------------------------------------
Company hereby makes the following representations and warranties to the
Purchaser:

                  (a)   Organization and Qualification. The Company is a
                        ------------------------------
corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware with the requisite corporate power and authority
to own and use its properties and assets and to carry on its business as
currently conducted. The Company is duly qualified to conduct business and is in
good standing as a foreign corporation or other entity in each jurisdiction in
which the nature of the business conducted or property owned by it makes such
qualification necessary.

                  (b)   Authorization. The Company has the requisite corporate
                        -------------
power and authority to enter into and to consummate the transactions
contemplated by this Agreement and otherwise to carry out its obligations
thereunder. The execution and delivery of this Agreement by the Company and the
consummation of the transaction contemplated hereby have been duly authorized by
all necessary action on the part of the Company and no further action is
required by the Company or its shareholders for the Company to execute and
consummate this Agreement and the transactions contemplated hereby. This
Agreement has been duly executed by the Company and, when delivered in
accordance with the terms hereof, and assuming the valid execution hereof by the
Purchaser, will constitute the valid and binding obligation of the Company
enforceable against the Company in accordance with its terms, except (a) as such
enforceability may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting creditors' rights generally, (b) as enforceability of any
indemnification and contribution provisions may be limited under the federal and
state securities laws and public policy, and (c) that the remedy of specific
performance and injunctive and other forms of equitable relief may be subject to
equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought.

                  (c)   No Conflicts. The execution, delivery and performance of
                        ------------
this Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby does not and will not: (i) conflict with or
violate any provision of the Company's certificate of incorporation or bylaws
(each as amended through the date hereof), or (ii) conflict with, or constitute
a default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment or
acceleration (with or without notice, lapse of time or both) of, any material
agreement or indebtedness to which the Company is a party or by which any
material property or asset of the Company is bound or affected, or (iii) result
in a violation of any law, rule, regulation, order, judgment, decree or other
restriction of any court, governmental authority or stock market to which the
Company or the Common Stock is subject.

<PAGE>

                  (d)   Issuance of the Shares. The Shares are duly authorized
                        ----------------------
and, when issued and paid for in accordance with the terms hereof, will be
legally issued, fully paid and nonassessable, free and clear of all liens and
encumbrances (other than any that are the result of any action or inaction of
the Purchasers). On the Closing Date the Company shall have secured the listing
of the Shares on the Nasdaq National Market (subject to official notice of
issuance).

                  (e)   Registration Statement. The Registration Statement is
                        ----------------------
effective and the Company has not received notice that the Commission has issued
or intends to issue a stop order with respect to the Registration Statement or
that the Commission otherwise has suspended or withdrawn the effectiveness of
the Registration Statement, either temporarily or permanently, or intends or has
threatened in writing to do so. The Registration Statement (including the
information or documents incorporated by reference therein), as of the time it
was declared effective, and any amendments or supplements thereto, each as of
the time of filing, did not contain any untrue statement of material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading. The Shares are registered under the Securities Act of 1933
(the "Securities Act"), as amended, by the Registration Statement.

                  (f)   Listing and Maintenance Requirements. The Company has
                        ------------------------------------
not, in the twelve months preceding the Execution Date, received notice from the
Nasdaq National Market to the effect that the Company is not in compliance with
the listing or maintenance requirements thereof. The Company is, and has no
reason to believe that it will not in the foreseeable future continue to be, in
compliance with the listing and maintenance requirements for continued trading
of the Common Stock on the Nasdaq National Market (except as a result of a
decline in the market price of the Common Stock) and currently meets the
standard prescribed therein with regard to net tangible assets.

                  (g)   Certain Fees. No fees or commissions will be payable by
                        ------------
the Company to any broker, financial advisor or consultant, finder, placement
agent, investment banker, bank or other Person with respect to the transactions
contemplated by this Agreement. The Purchaser will have no obligation with
respect to any fees incurred by the Company or any other Person (other than the
Purchaser, if the Purchaser has agreed in writing to pay such fees) or with
respect to any claims made by or on behalf of other Persons for fees of a type
contemplated in this Section that may be due in connection with the transactions
contemplated by this Agreement. The Company will indemnify and hold harmless the
Purchaser, its employees, officers, directors, agents,

<PAGE>

partners, and affiliates, from and against all claims, losses, damages, costs
(including the costs of preparation and reasonable attorney's fees) and expenses
suffered in respect of any such claimed or existing fees incurred by the Company
or any other Person, as such fees and expenses are incurred. "Person" means any
court or other federal, state, local or other governmental authority or other
individual or corporation, partnership, trust, incorporated or unincorporated
association, joint venture, limited liability company, joint stock company,
government (or an agency or subdivision thereof) or other entity of any kind.

                  (h)   Disclosure. Neither the Company nor any other Person
                        ----------
acting on its behalf has provided the Purchaser or their agents or counsel with
any information that constitutes or may, in the Company's opinion, constitute
material non-public information.

                  (i)   SEC Reports; Financial Statements. The Company has filed
                        ---------------------------------
all reports required to be filed by it under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), for the twelve months preceding the date
hereof (collectively, "SEC Reports") on a timely basis or has received a valid
extension of such time of filing and has filed any such SEC Reports prior to the
expiration of any such extension. As of their respective dates, the SEC Reports
complied in all material respects with the requirements of the Securities Act
and the Exchange Act and the rules and regulations of the Commission promulgated
thereunder, and none of the SEC Reports, when filed, contained any untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Reports comply in all material
respects with applicable accounting requirements and the rules and regulations
of the Commission with respect thereto as in effect at the time of filing. Such
financial statements have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved,
except as may be otherwise specified in such financial statements or the notes
thereto, and fairly present in all material respects the financial position of
the Company and its consolidated subsidiaries as of and for the dates thereof
and the results of operations and cash flows for the periods then ended,
subject, in the case of unaudited statements, to normal year-end audit
adjustments.

                  4.    Representations and Warranties of the Purchaser. The
                        -----------------------------------------------

insolvency, reorganization or similar laws affecting creditors' rights
generally, (b) as enforceability of any indemnification and contribution
provisions may be limited under the federal and state securities laws and public
policy, and (c) that the remedy of specific performance and injunctive and other
forms of equitable relief may be subject to equitable defenses and to the

                        ------------
this Agreement by the Purchaser and the consummation by the Purchaser of the
transactions contemplated hereby does not and will not (i) conflict with or
violate any provision of the Purchaser's certificate of incorporation or bylaws
(each as amended through the date hereof), or (ii) conflict with, or constitute
a default (or an event which with notice or lapse of time or both would become a
default) under, or give to others any rights of termination, amendment or
acceleration (with or without notice, lapse of time or both) of, any material
agreement or indebtedness to which the Purchaser is a party or by which any
material property or asset of the Purchaser is bound or affected, or (iii)

Purchaser is subject.

                        -------------------
each of its affiliates and other Persons acting on behalf of the Company not to
divulge to the Purchaser any information that it believes to be material
non-public information unless the Purchaser has agreed in writing to receive
such information prior to such divulgence. Neither the Company nor the Purchaser

other disposition) any of its or its affiliates' equity or equity equivalent
securities (including the issuance of any debt or other instrument at any time
over the life thereof convertible into or exchangeable for Common Stock).

         If to the Purchaser:   To the address set forth under the Purchaser's

                  (d)   Governing Law. All questions concerning the
                        -------------
construction, validity, enforcement and interpretation of this Agreement will be
governed by and construed and enforced in accordance with the internal laws of
the State of New York, without regard to the principles of conflict of laws
thereof. Each party agrees that all legal proceedings concerning the
interpretations, enforcement and defense of the transactions contemplated by
this Agreement (whether brought against a party hereto or its respective
affiliates, directors, officers, shareholders, employees or agents) will be
exclusively commenced in the state and federal courts sitting in the City of New
York, Borough of Manhattan. Each party hereto hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in the City of
New York, Borough of Manhattan for the adjudication of any dispute hereunder or
in connection herewith or with any transaction contemplated hereby or discussed
herein (including with respect to the enforcement of this Agreement), and hereby
irrevocably waives, and agrees not to assert in any suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of any such
court or that such courts are an improper or inconvenient forum. Each party
hereto hereby irrevocably waives personal service of process and consents to
process being served in any such suit, action or proceeding by mailing a copy
thereof via registered or certified mail or overnight delivery (with evidence of
delivery) to such party at the address in effect for notices to it under this
Agreement and agrees that such service will constitute good and sufficient
service of process and notice thereof. Nothing contained

<PAGE>

herein will be deemed to limit in any way any right to serve process in any
manner permitted by law. Each party hereto hereby irrevocably waives, to the
fullest extent permitted by applicable law, any and all right to trial by jury
in any legal proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby. If either party shall commence an action or
proceeding to enforce any provisions of this Agreement, then the prevailing
party in such action or proceeding will be reimbursed by the other party for its
reasonable attorneys fees and other reasonable costs and expenses incurred with
the investigation, preparation and prosecution of such action or proceeding.

                  (e)   Certain Remedies. In addition to being entitled to
                        ----------------
exercise all rights provided herein or granted by law, including recovery of
damages, the Purchaser and the Company will each be entitled to specific
performance of the others obligations under this Agreement. In furtherance
thereof, the parties agree that monetary damages may not be adequate
compensation for any loss incurred by reason of any such breach and hereby
agrees to waive in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate.

                  (f)   Execution. This Agreement may be executed in two or more
                        ---------
counterparts, all of which when taken together shall be considered one and the
same agreement and shall become effective when counterparts have been signed by
each party and delivered to the other party, it being understood that both
parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission, such signature shall create a valid and
binding obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

         IN WITNESS WHEREOF, the parties hereto have caused this Purchase
Agreement to be duly executed as of the date first indicated above.
