filings by the Company with the Securities and Exchange Commission after the

SECTION  4. REPRESENTATIONS AND WARRANTIES OF THE INVESTOR

         The Investor hereby represents and warrants for itself, and not for any
other Investor that:

         4.1      AUTHORIZATION

         All corporate or other similar action, if any, required on the part of
the Investor for the authorization, execution and delivery of this Agreement and
the other agreements and transactions contemplated herein, and the performance
of all of the Investor's obligations hereunder and thereunder have been taken,
and this Agreement constitutes, and when executed and delivered by the Investor
the other agreements contemplated herein to which the Investor is a party will
constitute, valid and legally binding obligations of the Investor, enforceable
in accordance with their respective terms, except as to the effect, if any, of
(a) applicable bankruptcy and other similar laws affecting the rights of
creditors generally, (b) rules of law governing specific performance, injunctive
relief and other equitable remedies, and (c) the enforceability of provisions
requiring indemnification in connection with the offering, sale or issuance of
securities. The Investor has full power and authority to execute, deliver and
perform its obligations under this Agreement and such other agreements and to
own the Common Stock to be received by the Investor hereunder (collectively, the
"Securities").

         4.2      PURCHASE ENTIRELY FOR OWN ACCOUNT

         This Agreement is made with the Investor in reliance upon the
Investor's representation to the Company, which by the Investor's execution of
this Agreement

STOCK PURCHASE AGREEMENT                                              PAGE 4



the Investor hereby confirms, that the Securities will be acquired for
investment for the Investor's own account, and not with a view to the
distribution of any part thereof, and that the Investor has no present
intention of selling, granting any participation in, or otherwise
distributing the same in a manner contrary to the Securities Act of 1933, as
amended (the "Act"), or applicable state securities laws.

         4.3      DISCLOSURE OF INFORMATION; DUE DILIGENCE

         The Investor has received and reviewed a copy of each SEC Document. The
Investor represents and acknowledges that it has been solely responsible for its
own "due diligence" investigation of the Company and of the management and
business of the Company, for its own analysis of the merits and risks of this
investment, and for its own analysis of the fairness and desirability of the
terms of the investment; that in taking any action or performing any role
relative to the arranging of the proposed investment, the Investor has acted
solely in its own interests.

         4.4      INVESTMENT EXPERIENCE; ACCREDITED INVESTOR STATUS

         The Investor is an investor in securities of the type of the Common
Stock and acknowledges that the Securities are a speculative risk. The Investor
is able to fend for itself in the transactions contemplated by this Agreement,
can bear the economic risk of its investment (including possible complete loss
of such investment) for an indefinite period of time and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits and risks of the investment in the Securities. The Investor represents it
has not been organized for the purpose of acquiring the Securities. The Investor
understands that the Securities have not been registered under the Act, or under
the securities laws of any jurisdiction, by reason of reliance upon certain
exemptions, and that the reliance of the Company on such exemptions is
predicated upon the accuracy of the Investor's representations and warranties in
this Section 4. The Investor is familiar with Regulation D promulgated under the
Act and is an "accredited investor" as defined in Rule 501(a) of such Regulation
D.

         4.5      RESTRICTED SECURITIES

         The Investor understands that the Securities are characterized as
"restricted securities" under the federal 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 such securities may be
resold without registration under the Act only in certain limited circumstances
and in accordance with the terms and conditions set forth in the legend
described in Section 4.6 below. In this connection, the Investor represents that
it is familiar with Rule 144 promulgated under the Act, as

STOCK PURCHASE AGREEMENT                                              PAGE 5



currently in effect, and understands the resale limitations imposed thereby
and by the Act.

         4.6      LEGEND

         It is understood that the certificates evidencing the Securities may
bear the following or a similar legend:

         THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR APPLICABLE
         STATE LAW, AND NO INTEREST THEREIN MAY BE SOLD, DISTRIBUTED, ASSIGNED,
         OFFERED, PLEDGED OR OTHERWISE TRANSFERRED UNLESS (i) THERE IS AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND APPLICABLE STATE
         SECURITIES LAWS COVERING ANY SUCH TRANSACTION INVOLVING SAID
         SECURITIES, (ii) THIS CORPORATION RECEIVES AN OPINION OF LEGAL COUNSEL
         FOR THE HOLDER OF THESE SECURITIES SATISFACTORY TO THIS CORPORATION
         STATING THAT SUCH TRANSACTION IS EXEMPT FROM REGISTRATION, OR (iii)
         THIS CORPORATION OTHERWISE SATISFIES ITSELF THAT SUCH TRANSACTION IS
         EXEMPT FROM REGISTRATION.

         4.7      RESIDENCY

         For purposes of the application of state securities laws, the Investor
represents that it is a resident of the state set forth opposite the Investor's

federal and state securities laws, which qualification or exemption the Company

conditions:

         6.1      REPRESENTATIONS AND WARRANTIES

         The representations and warranties of the Investor contained in Section

         (a)      Subject to Section 7(b) below, the Company shall file, with
respect to the shares of Common Stock purchased under this Agreement, a
registration statement on Form S-3 (or any successor form) on or before the
180th day after the Closing Date to register the Securities held by the Investor
under the Act. The Company shall use commercially reasonable efforts to have the
registration statement declared effective

STOCK PURCHASE AGREEMENT                                              PAGE 7



and to maintain the effectiveness of such registration statement (and
maintain the current status of the prospectus or prospectuses contained
therein) for at least 120 days.

         (b)      The Company shall not be obligated to effect any such
registration pursuant to Section 7(a):

                  (1)      if Form S-3 is not available for such offering by the
         Investor;

                  (2)      if the Company shall furnish to the Investor a
         certificate signed by the President or Chief Executive Officer of the
         Company stating that in the good faith judgment of the Board of
         Directors of the Company, it would be materially detrimental to the
         Company and its shareholders for such Form S-3 registration to be
         effected at such time, in which event the Company shall have the right
         to defer the filing of the Form S-3 registration statement for a period
         of not more than ninety (90) days after the expiration of the 180-day
         period set forth above; or

                  (3)      in any particular jurisdiction in which the Company
         would be required to qualify to do business or to execute a general
         consent to service of process in effecting such registration.

         (c)      The Company shall notify the Investor in writing at least
thirty (30) days prior to filing any registration statement under the Act for
purposes of effecting a public offering of securities of the Company (including,
but not limited to, registration statements relating to secondary offerings of
securities of the Company, but excluding registration statements relating to any
registration under Section 7(a) of this Agreement or to any employee benefit
plan or a corporate reorganization) and will afford the Investor an opportunity
to include in such registration statement all or any part of the Securities then
held by the Investor, subject to the provisions of Sections 7(d) and 7(e) below.
If the Investor wants to include in any such registration statement all or any
part of the Securities held by the Investor, the Investor shall within twenty
(20) days after receipt of the above-described notice from the Company, so
notify the Company in writing, and in such notice shall inform the Company of
the number of Securities the Investor wishes to include in such registration
statement.

         (d)      If a registration statement under which the Company gives
notice under Section 7(c) is for an underwritten offering, then the Company
shall so advise the Investor. In such event, the right of the Investor to
include any of the Investor's Securities in a registration pursuant to Section
7(c) shall be conditioned upon the Investor's participation in such underwriting
and the inclusion of the Investor's Securities in the underwriting on the same
terms and conditions as the other

STOCK PURCHASE AGREEMENT                                              PAGE 8



participants in such offering, including, without limitation, entering into
an underwriting agreement in customary form with the managing underwriter or
underwriters selected for such underwriting (including a market stand-off
agreement of up to 180 days if required by such underwriters).
Notwithstanding any other provision of this Agreement, if the managing
underwriter(s) determine(s) in good faith that marketing factors require a
limitation of the number of shares to be underwritten, then the managing
underwriter(s) may exclude shares from the registration and the underwriting,
and the number of shares that may be included in the registration and the
underwriting shall be allocated, FIRST, to the Company, SECOND, to each
holder of registration rights granted by the Company before the date of this
Agreement that contractually require the Company to include such holder's
shares on a priority basis, and THIRD, to the Investor and any other holder
of registration rights granted by the Company (excluding those covered
above), on a pro rata basis based on the total number of shares of Common
Stock then sought to be included by each in such offering. If the Investor
disapproves of the terms of any such underwriting, the Investor may elect to
withdraw therefrom by written notice to the Company and the underwriter(s),
delivered at least ten (10) business days prior to the effective date of the
registration statement. Any Securities excluded or withdrawn from such
underwriting shall be excluded and withdrawn from the registration.

         (e)      The Investor may not have any Securities registered pursuant
to any registration statement initiated pursuant to the Registration Rights
Agreement, dated as of June 9, 1999, among the Company, Strong River Investment
Inc., and Bay Harbor Investments, Inc.

SECTION 8. MISCELLANEOUS

         8.1      SURVIVAL OF WARRANTIES

         The warranties, representations and covenants contained in or made
pursuant to this Agreement shall survive the execution and delivery of this
Agreement and the Closing.

         8.2      SUCCESSORS AND ASSIGNS

         The terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective successors, assigns, heirs and legal
representatives of the parties. Nothing in this Agreement, express or implied,
is intended to confer upon any party other than the parties hereto and their
respective successors and assigns any rights, remedies, obligations or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement.
