                  WHEREAS, the Company intends to sell, in an offering exempt

                  WHEREAS, the Offering commenced on July 17, 2001 and will
terminate at 5:00 p.m., Eastern Standard Time, on August 15, 2001 (the
"Termination Date") (unless such Termination Date is extended as described in
Section 1.03 hereof); and

                  WHEREAS, the Company desires to sell to Purchaser, and
Purchaser desires to subscribe to purchase, that number of shares of Common

The shares of Common Stock being subscribed for by Purchaser hereunder are

hereunder are hereinafter referred to as the "Warrant Shares".

                  NOW, THEREFORE, in consideration of the mutual covenants and
agreements set forth in this Agreement, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                                    ARTICLE I

escrow agent (the "Escrow Agent"). Pursuant to the Escrow Agreement, the
Purchase Price received from Purchaser, and the purchase price received from any
other purchaser in the Offering, shall be deposited, pending the Closing or

Offering for a period of up to 15 days from and after August 15, 2001 (whereupon

to the Company the Purchase Price and the Company will deliver to Purchaser a
certificate or certificates representing the number of Warrants purchased by
Purchaser (the "Warrant Certificates"). At or promptly after the Closing, the
Company will deliver to Purchaser a certificate or certificates representing the
Common Shares purchased by Purchaser (the "Share Certificates"). The terms of
this Agreement shall be the same as the terms of any other Subscription
Agreements entered into and delivered by other purchasers in connection with the
Offering. The Company may terminate the Offering prior to the Termination Date
upon written notice to the Escrow Agent and Purchaser. If the Company terminates

Purchaser without interest, deduction, penalty or expense.

                  1.04   Restrictive Legend. Each Share Certificate and each
Warrant Certificate issued by the Company will bear a legend in the following
terms:

         THEREFROM."

All of the restrictions imposed by this Section 1.04 upon the transferability of

certificate evidencing such Common Share, Warrant or Warrant Share not bearing

evidencing such Common Share, Warrant or Warrant Share; provided that the
Company may require an opinion of counsel reasonably satisfactory to it to the
effect that no legend is required under the Securities Act and applicable state
securities laws or foreign securities laws.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

                  The Company hereby represents and warrants to Purchaser as
follows:

                  2.01     Organization and Qualification. Each of the Company
and its Subsidiaries is a corporation duly incorporated, validly existing and in
good standing under the Laws of its jurisdiction of incorporation, and has all
requisite corporate power and authority to conduct its business as and to the
extent now conducted and to own, use and lease its Assets and Properties, except
for such failures to be in good standing or to have such power and authority
which, individually or in the aggregate, are not having a Material Adverse
Effect on the Company and its Subsidiaries taken as a whole. Each of the Company
and its Subsidiaries is duly qualified, licensed or admitted to do business and
is in good standing in each jurisdiction in which the ownership, use or leasing
of its Assets and Properties, or the conduct or nature of its business, makes
such qualification, licensing or admission necessary, except for such failures
to be so qualified, licensed or admitted and in good standing which,
individually or in the aggregate, are not having a Material Adverse Effect on
the Company and its Subsidiaries taken as a whole. Except for interests in the
Subsidiaries of the Company and as disclosed in the Company SEC Reports (as
defined below) filed prior to the date of this Agreement, the Company does not
directly or indirectly own any equity or similar interest in, or any interest
convertible into or exchangeable or exercisable for, any equity or similar
interest in, any corporation, partnership, joint venture or other business
association or entity. The Company has previously delivered to Purchaser correct
and complete copies of the certificate or articles of incorporation and bylaws
(or other comparable charter documents) of the Company and each of its material
Subsidiaries.

                  2.02     Authority. The Company has the requisite corporate
power and authority to execute and deliver this Agreement and to perform its
obligations hereunder and to consummate the transactions contemplated hereby.
The execution, delivery and performance by the Company of this Agreement and the
consummation by the Company of the transactions contemplated hereby have been
duly and validly approved by the Board of Directors of the Company. No other
corporate proceedings on the part of the Company or its stockholders are
necessary to authorize the execution, delivery and performance by the Company of
this Agreement and the consummation by the Company of the transactions
contemplated hereby. This Agreement has been duly and validly executed and
delivered by the Company and constitutes the valid and binding obligation of the
Company enforceable against the Company in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar Laws affecting the enforcement of creditors' rights
generally and by general equitable principles (regardless of whether such
enforceability is considered in a proceeding in equity or at Law). The Common
Shares, when issued in accordance with this Agreement, and the Warrant Shares,
when issued upon exercise of the Warrants, will be duly authorized, validly
issued, fully paid and non-assessable.

                  2.03     Capital Stock. (a) The authorized capital stock of
the Company consists solely of 100,000,000 shares of Common Stock and 5,000,000

outstanding (excluding 39,891 shares held in treasury), (ii) 2,683,938 shares

Except as set forth in Section 2.03(a) of the Company Disclosure Schedule, since
such date, there has been no change in the number of issued and outstanding
shares of Common Stock. As of the date hereof, no shares of Preferred Stock are
issued and outstanding. All of the issued and outstanding shares of Common Stock
and all shares of Common Stock reserved for issuance will be, upon issuance in
accordance with the terms specified in the instruments or agreements pursuant to
which they are issuable, duly authorized, validly issued, fully paid and
nonassessable. Except pursuant to this Agreement, pursuant to other Subscription
Agreements entered into in connection with the Offering, as disclosed in the
Company SEC Reports (as defined below) filed prior to the date of this Agreement
or as set forth in Section 2.03(a) of the Company Disclosure Schedule, there are

Disclosure Schedule, there are no (i) outstanding Options obligating the Company
or any of its Subsidiaries to issue or sell any shares of capital stock of any
Subsidiary of the Company or to grant, extend or enter into any such Option or

or arrangements in favor of any person other than the Company or a Subsidiary
wholly owned, directly or indirectly, by the Company with respect to the voting
of or the right to participate in dividends or other earnings on any capital
stock of any Subsidiary of the Company.

                  (c)      There are no outstanding contractual obligations of
the Company or any Subsidiary of the Company to repurchase, redeem or otherwise
acquire any shares of Common Stock or any capital stock of any Subsidiary of the
Company or to provide funds to, or make any investment (in the form of a loan,
capital contribution or otherwise) in, any Subsidiary of the Company or any
other person.

and delivery by the Company of this Agreement, and the performance by the
Company of its obligations hereunder and the consummation of the transactions
contemplated hereby, will not:

                   REPRESENTATIONS AND WARRANTIES OF PURCHASER

                  Purchaser hereby represents and warrants to the Company as to
himself or itself as follows:

                  3.01     Organization. To the extent Purchaser is an entity,

consummation by Purchaser of the transactions contemplated hereby, have been
duly and validly approved by Purchaser, no other action on the part of Purchaser
or its equityholders being necessary for Purchaser to execute, deliver and
perform its obligations hereunder. This Agreement has been duly and validly
executed and delivered by Purchaser and constitutes a legal, valid and binding
obligation of Purchaser enforceable against Purchaser in accordance with its
terms, except as enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium or other similar Laws affecting the enforcement of
creditors' rights generally and by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at Law).

                  3.03     No Conflicts; Approvals and Consents. (a) The
execution and delivery of this Agreement by Purchaser does not, and the
performance by Purchaser of its obligations hereunder and the consummation of
the transactions contemplated hereby will not:

                  (i)      if Purchaser is an entity, conflict with or result in
a violation or breach of any of the terms, conditions or provisions of the
certificate of incorporation, by-laws, limited liability agreement or trust
agreement (or other comparable corporate charter document) of Purchaser;

                  (ii)     conflict  with or result in a violation  or
breach of any term or provision of any Law or Order applicable to Purchaser or
any of its Assets and Properties; or

                  (iii)    (A) conflict with or result in a violation or breach
of, (B) constitute (with or without notice or lapse of time or both) a default
under, (C) require Purchaser to obtain any consent, approval or action of, make
any filing with or give any notice to any Person as a result or under the terms
of, or (D) result in the creation or imposition of any Lien upon Purchaser or
any of its Assets or Properties under, any contract or License to which
Purchaser is a party or by which any of its Assets and Properties is bound.

                  (b) no consent, approval or action of, filing with or notice
to any Governmental or Regulatory Authority on the part of Purchaser is required
in connection with the execution, delivery and performance of Purchaser's
obligations hereunder or the consummation of the transactions contemplated
hereby.

<PAGE>

                  3.04     Legal Proceedings. There are no Actions or
Proceedings pending or, to the knowledge of Purchaser, threatened against,
relating to or affecting Purchaser or any of its Assets and Properties which
could reasonably be expected to result in the issuance of an Order restraining,
enjoining or otherwise prohibiting or making illegal the consummation of any of
the transactions contemplated by this Agreement.

                  3.05     Purchase of Shares. (a) Purchaser acknowledges that
this Agreement is made with Purchaser in reliance upon Purchaser's
representation to the Company, which by Purchaser's execution of this Agreement
Purchaser hereby confirms, that the Common Shares and the Warrants (and any
Warrant Shares issued upon exercise of the Warrants) are being acquired by
Purchaser and will be acquired for investment for Purchaser's own account, not
as a nominee or agent, and not with a view to the resale or distribution of any
part thereof, and that Purchaser has no present intention of selling, granting
any participation in, or otherwise distributing the same; provided, however,
that by making the representations herein, Purchaser does not agree to hold the
Common Shares, Warrants or any Warrant Shares for any minimum or other specific
term and reserves the right to dispose of the Common Shares, the Warrants and
Warrant Shares at any time in accordance with or pursuant to a registration
statement or an exemption under the Securities Act and in accordance with the
applicable provisions of the Registration Rights Agreement and the Warrants. By
executing this Agreement, Purchaser further represents that it does not
presently have any contract, undertaking, agreement or arrangement with any
Person to sell, transfer or grant participations to such Person or to any third
Person, with respect to any of the Common Shares, Warrants or Warrant Shares.
Purchaser represents that either (i) Purchaser has not been formed for the
specific purpose of acquiring the Common Shares, Warrants or Warrant Shares or
(ii) if Purchaser has been formed for the specific purpose of acquiring the
Common Shares, Warrants or Warrant Shares, each Person that has an interest in
Purchaser is an "accredited investor" within the meaning of Rule 501 under the
Securities Act.

                  (b)      Purchaser has had an opportunity to discuss the
Company's business, management, financial affairs and the terms and conditions
of the sale of the Common Shares and Warrants pursuant to this Agreement with
the Company's management. Purchaser acknowledges receipt from the Company of
copies of the Company SEC Reports and such other information about the Company
as Purchaser or its advisors, if any, have requested. Purchaser understands that
such discussions, as well as the Company SEC Reports and other information
requested by Purchaser or its advisors, if any, and received from the Company,
were intended to describe the aspects of the Company's business which it
believes to be material.

                  (c)      Purchaser understands that none of the Common Shares,
Warrants or Warrant Shares have been, and none of them will be, registered under
the Securities Act, by reason of a specific exemption from the registration
provisions of the Securities Act which depends upon, among other things, the
bona fide nature of the investment intent and the accuracy of Purchaser's
representations and warranties as expressed in this Article III. Purchaser
understands that the Common Shares, Warrants or Warrant Shares are "restricted
securities" under applicable United States federal and state securities laws and
that, pursuant to these laws, Purchaser must hold the Common Shares, Warrants or
Warrant Shares indefinitely unless they are registered with the SEC, or an
exemption from such registration and qualification requirements is available.
Purchaser acknowledges that the Company has no obligation to register or qualify
the Common Shares, Warrants or Warrant Shares for resale except as expressly
provided under the Registration Rights Agreement. Purchaser further acknowledges
that if an exemption from registration or qualification is available, it may be
conditioned on various requirements including, but not limited to, the time and
manner of sale, the holding period for the Common Shares, Warrants or Warrant
Shares, and on requirements relating to the Company which are outside of
Purchaser's control, and which the Company is under no obligation and may not be
able to satisfy.

<PAGE>

                  (d)      Purchaser has such knowledge and experience in
financial and business matters that Purchaser is capable of evaluating the
merits and risks of the transactions contemplated hereby, including the purchase
of the Common Shares, Warrants and the Warrant Shares.

                  (e)      Purchaser is able to bear the economic risk of
acquiring Common Shares, Warrants and the Warrant Shares and to hold the Common
Shares, Warrants and Warrant Shares acquired by Purchaser pursuant to this
Agreement for an indefinite period of time.

                  3.06     Accredited Investor Status. Purchaser is an
"accredited investor" within the meaning of Rule 501 under the Securities Act
and represents that the Accredited Investor Certification executed by Purchaser,
the form of which is attached as Exhibit C to this Agreement, is true, correct
and complete.
