(collectively, the "Obligors") to the Lender (the "Security Agreement"), and (b)

         WHEREAS, the Borrower has failed to make the scheduled payment of

and the Parent Assignment (collectively, the "Loan Documents") from December 13,
2001 through June 13, 2002 (the "Forbearance Period") with respect to certain
existing and anticipated Events of Defaults; and

         WHEREAS, Lender is willing to grant such a forbearance and enter into
such amendment, but only upon the terms and conditions herein contained;

         NOW THEREFORE, the Obligors and the Lender hereby agree as follows:

         SECTION 1. Recitals. The Recitals are incorporated into this Agreement
by reference.

         SECTION 2. Forbearance. The Lender hereby agrees to forbear from
accelerating the indebtedness evidenced by the Note during the Forbearance
Period and to refrain during the Forbearance Period from taking any enforcement
actions against the Borrower, but only to the extent that the Events of Defaults
giving rise to such remedies relate to failure to make the principal and
interest payments due on December 13, 2001, January 13, 2002, February 13, 2002,
March 13, 2002, April 13, 2002 and May 13, 2002 under the Note (the
"Acknowledged Defaults").

         SECTION 3. Forbearance Fee. The Obligors hereby reaffirm their
obligation to jointly and severally agree to pay to Lender the sum of $39,536.71
as a Forbearance Fee (the "Forbearance Fee"), such Forbearance Fee to be due and
payable on June 13, 2002. The parties agree that the Forbearance Fee id the
Forbearance Fee described in Section 3 of that certain Forbearance Agreement and
First Amendment to Loan Documents among the parties hereto (the "Prior
Agreement") which was executed but as to which certain provisions relating to
Lender's forbearance failed to become effective as a result of the failure of
the Obligors to satisfy certain conditions precedent contained therein. The
Obligors agree that the Forbearance Fee was fully earned on the date of the
Prior Agreement and continues to be earned on the date hereof.

         SECTION 4. Effect of Waiver. Except as set forth expressly herein, all
terms of the Note and the other Loan Documents shall be and remain in full force
and effect, and shall constitute the legal, valid, binding and enforceable
obligations of the Obligors. The forbearance set forth in Section 2 hereof: (a)
shall relate only to the Acknowledged Events of Default, and (b) is subject to
the satisfaction of the conditions precedent set forth in Section 7 hereof. The
waiver hereby granted by the Lender shall not apply to any other past, present
or future noncompliance with any provision of the Note or any of the other Loan
Documents (including, without, limitation, any Event of Default occurring or in
existence after the end of the Forbearance Period, whether or not related to an
Acknowledged Event of Default), and all rights, powers and remedies of the
Lender are reserved with respect thereto).

         SECTION 5. No Novation or Mutual Departure. The Obligors expressly
acknowledge and agree that: (a) there has not been, and this Agreement does not
constitute or establish, a novation with respect to the Note or any of the Loan
Documents, or a mutual departure from the strict terms, provisions and
conditions thereof, other than as specifically specified in Section 2 hereof;
and (b) nothing in this Waiver shall affect or limit the Lender's right to
demand payment of liabilities owing from the Obligors under, or to demand strict
performance of the terms, provisions and conditions of, the other Loan Document,
to exercise any and all rights, powers and remedies under the Loan Documents or

                                       2
<PAGE>

at law or in equity, or to do any and all of the foregoing, immediately at any
time after (a) the occurrence of an Event of Default, other than arising from an
Acknowledged Event of Default during the Forbearance Period or (b) the
occurrence of any Event of Default after the Forbearance Period.

         SECTION 6. Amended and Restated Note. The Obligors are
contemporaneously herewith executing and delivering to the Lender that certain
Amended and Restated Secured Promissory Note (the "Restated Note") in form and
substance as attached hereto as Exhibit A. Lender shall hold the Restated Note
in escrow and the Restated Note shall not be effective until June 13, 2002;
provided however that the parties agree that Lender shall only release the
Restated Note from escrow on June 13, 2002 if (a) the conditions precedent set
forth in Section 7 hereof are satisfied, and (b) no Event of Default other than
the Acknowledged Defaults shall have occurred during the Forbearance Period.

in its entirety effective as of May 10, 2002.

         SECTION 7. Conditions to Effectiveness. This Agreement is effective
when duly executed by all parties, but Section 2 of this Agreement shall become
effective when all of the following conditions have been satisfied, provided
however, that if all such conditions are not satisfied on or before May 13,
2002, Section 2 shall be of no force or effect:

              (a) the Lender shall have received the Restated Note, duly
executed by the Borrower;

              (b) the Lender shall have received counterparts of this Agreement
executed by the Obligors and the Lender;

              (c) the Lender shall have received true, correct and complete
(including all attachments) file-stamped copies of each of the financing

financing statement shall be preceded by a cover sheet indicating the
jurisdiction in which such statement was filed and date such statement was
filed;

              (d) the Lender shall have received the Consent and Acknowledgement
of Shaar Fund, Ltd. in form and substance as set forth in Exhibit B; and

constitute an Event of Default under the Note or any of the other Loan Documents
but for the giving of notice or the passage of time, or both (other than the
Acknowledged Defaults"), and the execution, delivery and performance of this
Agreement shall not cause or constitute any such default or any such Event of
Default under any of the Loan Documents, as amended hereby.

         SECTION 9. References to and Effect on the Facility Documents.

              (a) Upon the effectiveness of the Restated Note, on and after the
date hereof, each reference in the Loan Documents to "the Note," or words of
like import shall mean and be a reference to the Restated Note.

              (b) Except as specifically amended herein, the Loan Documents and
the Warrant Documents remain in full force and effect and are hereby ratified
and confirmed. Without limiting the generality of the foregoing, (i) the
Guaranty does and shall continue to secure the payment of all of Borrower's
obligations under to Lender, whether primary or secondary, direct, absolute or
contingent, sole, joint and/or several, heretofore, now or hereafter acquired or

<PAGE>

              (c) The execution, delivery and effectiveness of this Agreement
shall not, except as expressly provided herein, operate as a waiver of any
right, power or remedy of the Lender under any of the Loan Documents or under
any of the Warrant Documents, nor constitute a waiver of any provision of any of
the foregoing.

         SECTION 10. Acknowledgment of Outstanding Loans. The Obligors hereby
acknowledge, certify and agree that: the obligations of the Obligors to repay
