                                   BACKGROUND

setting forth the preferences, rights and restrictions applicable to the Series

      WHEREAS, each of the LLR Purchase Agreement, the certificates representing
the Warrants (the "Warrant Certificates"), the certificates representing the
Anti-Dilution Warrants (the "Anti-Dilution Warrant Certificates"), the Series B
Designation, the Series C Designation, and the other Transaction Agreements (as
such term is defined in the LLR Purchase Agreement) grant various rights to the
Sellers, including, but not limited to, preemptive, registration and
anti-dilution rights, all of which rights are referred to collectively in this
Agreement as the "LLR Rights";

      WHEREAS, since September 1, 2000, the Sellers have purchased an additional
39,600 shares of the Common Stock in the open market (the "Additional Common
Shares," and together with the Initial Common Shares, the "Common Shares");

      WHEREAS, the Company wishes to purchase from the Sellers, on the terms and

(d) the Anti-Dilution Warrants; (e) the Exchange Rights; and (f) the LLR Rights

      WHEREAS, the Sellers wish to sell to the Company the LLR Interests on the
terms and subject to the conditions set forth in this Agreement;

      WHEREAS, the Company anticipates that it will effect a firm-commitment
underwritten public offering of shares of the Common Stock with aggregate
proceeds of at least $20 million (the "Public Offering") or will otherwise
consummate a sale of its equity securities (other than in connection with the
exercise of any warrants, options or other subscription or purchase rights or
pursuant to the exercise of any conversion or exchange rights outstanding as of
the date hereof) with aggregate proceeds of at least $18 million (an "Offering")
and that it will use a portion of the proceeds of the Public Offering or an
Offering to pay the purchase price for the LLR Interests.

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
and agreements contained in this Agreement, and intending to be legally bound
hereby, the parties agree as follows:

                                   ARTICLE I
                SALE AND PURCHASE OF SHARES AND WARRANTS; CLOSING

      1.1 Sale and Purchase of LLR Interests.

            (a) Upon the terms and subject to the conditions of this Agreement,
on the Closing Date (as hereinafter defined), the Sellers shall sell and deliver
to the Company and the Company shall purchase and take from the Sellers, the
following: (i) the Common Shares less the Retained Shares (as defined below);
(ii) the Series B Preferred Shares; (iii) the Warrants; (iv) the Anti-Dilution
Warrants; (v) the Exchange Rights; and (vi) the LLR Rights (except to the extent
set forth in Section 1.3 hereof). "Retained Shares" means a number of shares of
Common Stock equal to the quotient of $2,000,000 divided by (i) the offering
price per share of the Common Stock sold in the Public Offering, if the Closing
is in connection with a Public Offering, or (ii) the Average Closing Price of
the Common Stock if the Closing is in connection with an Offering. The "Average
Closing Price" of the Common Stock shall mean as follows: (a) if traded through
the NASDAQ National Market, the average of the closing prices of the Common
Stock over the 20 trading day period ending the trading day immediately prior to
the Closing Date; (b) if not traded through the NASDAQ National Market, but
traded on a securities exchange, the average of the closing prices of the Common
Stock over the 20 day trading period ending the trading day immediately prior to
the Closing Date; and (c) if neither (a) nor (b) is the case, but Common Stock
is traded over-the-counter, the value shall be deemed to be the average of the
closing bid or sale prices (whichever is applicable) over the 20 trading day
period ending the trading day immediately prior to the Closing Date. The Sellers
shall retain the Retained Shares out of their Common Shares.

                                      -2-

immediately prior to the Closing, stock certificates representing the Retained

Warrants, the Anti-Dilution Warrants, or the certificates representing the
Common Shares or the Series B Preferred Shares shall be lost, stolen or
destroyed, the Sellers shall deliver to the Company an affidavit of that fact
and an undertaking of indemnity by the Sellers claiming such Warrants,
Anti-Dilution Warrants, or certificates representing the Common Shares or the
Series B Preferred Shares to be lost, stolen or destroyed.

            (c) At the Closing, the Company will deliver to the Sellers the
Purchase Price, by wire transfer of immediately available funds in U.S. dollars,
to a bank in the United States specified by the Sellers for the account of the
Sellers.

            (d) If the Closing does not occur on or prior to January 31, 2005,
this Agreement shall terminate and the parties hereto shall have no obligations
with respect to this Agreement.

      1.3 Transaction Agreements. Notwithstanding anything herein to the
contrary, the Sellers shall be entitled to the rights and subject to the
obligations set forth in Sections 2.4, 2.5, 2.7, and 2.13 of that certain
Registration Rights Agreement, dated as of September 1, 2000, by and among the
Company and the Sellers (the "Registration Rights Agreement"), so long as the

willful misconduct perpetrated against the Company by Sellers. The foregoing

indemnification obligation that the Company has to Seth J. Lehr and John L.
Gavin as a result of being or having been members of the Board of Directors of

or at such other address as the intended recipient previously shall have
designated by written notice to the other parties. Notice by courier mail shall
be effective on the date it is officially recorded as delivered to the intended
recipient by return receipt or equivalent. All notices and other communications
required or contemplated by this Agreement delivered in person or sent by
facsimile shall be deemed to have been delivered to and received by the
addressee and shall be effective on the date of personal delivery or at the time
of confirmation, respectively. Notice not given in writing shall be effective
only if acknowledged in writing by a duly authorized representative of the party
to whom it was given.

      8.6 Integration. This Agreement (including any Exhibits and Schedules
hereto) and other documents delivered pursuant hereto constitute the entire
understanding of the parties with respect to the subjects hereof and thereof.
There are no restrictions, agreements, promises, warranties, covenants or
undertakings other than those expressly set forth herein or therein with respect
to any matter.

      8.7 Waivers. No failure or delay on the part of either party in the
exercise of any power, right or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any such power, right or
privilege preclude other or further exercise thereof or of any other right,
power or privilege. All rights and remedies existing under this Agreement are
cumulative to, and not exclusive of, any rights or remedies otherwise available.

      8.8 Governing Law. This Agreement shall be exclusively governed by,
construed in accordance with, and interpreted according to the substantive law
of the State of Delaware without giving effect to the principles of conflict of
laws.

      8.9 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
together shall constitute one and the same instrument. A facsimile transmission
of an original signature shall be deemed to be an original signature.

      8.10 Cooperation. The parties hereto shall each perform such acts, execute
and deliver such instruments and documents and do all such other things as may
be reasonably necessary to accomplish the transactions contemplated in this
Agreement.

      8.11 Section Headings and Captions. Section headings and captions used in
this Agreement are provided for convenience only and shall not affect this
Agreement's meaning or interpretation.

      8.12 Delivery by Facsimile. This Agreement, the agreements and instruments
referred to herein, and each other agreement or instrument entered into in
connection herewith or therewith or contemplated hereby or thereby, and any
amendments hereto or thereto, to the extent signed and delivered by means of a
facsimile machine, shall be treated in all manner and respects as an original
agreement or instrument and shall be considered to have the same binding legal
effect as if it were the original signed version thereof delivered in person. At
the request of any party hereto or to any such agreement or instrument, each
other party hereto or thereto shall reexecute original forms thereof and deliver
them to all other parties. No party hereto or to any such agreement or
instrument shall raise the use of a facsimile machine to deliver a signature or

                                      -10-

the fact that any signature or agreement or instrument was transmitted or
communicated through the use of a facsimile machine as a defense to the
formation or enforceability of a contract and each such party forever waives any
such defense.

      8.13 Interpretation of Agreement. The parties hereto acknowledge and agree
that this Agreement has been negotiated at arm's-length and among parties
equally sophisticated and knowledgeable in the matters dealt with in this
Agreement. Accordingly, any rule of law or legal decision that would require
interpretation of any ambiguities in this Agreement against the party that has
drafted it is not applicable and is waived. The provisions of this Agreement
shall be interpreted in a reasonable manner to effect the intent of the parties
as set forth in this Agreement.
