         NOW, THEREFORE, based on these premises, and in consideration of the
mutual promises, representations and warranties, covenants and conditions
contained herein and other good and valuable consideration, the receipt and
adequacy of which is hereby acknowledged, and intending to be legally bound, the
parties hereto hereby agree as follows:

         1. Definitions. Capitalized terms used herein, and not otherwise
defined herein, shall have the meanings assigned to them in the Loan Agreement.

         2. Acknowledgment of Obligations.

              (a) Each Borrower acknowledges and agrees that, (i) as of the
Effective Date, such Borrower is unconditionally liable to the Lender on a joint
and several basis under the Loan Agreement and each of the Other Documents, for
the payment of the principal amount of the Loans (as described in clause (ii)
hereof), plus all accrued and unpaid interest through the Effective Date, plus
all expenses incurred by the Lender through the Effective Date, including,
without limitation reasonable attorneys' fees and expenses, and that, as of the

credits, claims or rights of setoff or recoupment with respect to the such
obligations, and (ii) as of December 12, 2002, the aggregate outstanding
principal balance of (A) the Revolving Credit Loans is $7,500,000, (B) the
Equipment Loans is $96,666.66, (C) Term Loan A is $2,151,111.12 and (D) Term

agrees that the Loan Agreement and the Other Documents remain in full force and
effect.

         3. Acknowledgment of Occurrence of Events of Default; Forbearance.

              (a) The Borrowers acknowledge and agree that certain Events of
Default have occurred and are continuing under the Loan Agreement and that, as a
consequence, the Lender has the right to immediately exercise its rights and
remedies under and in accordance with the Loan Agreement and the Other
Documents. Each Borrower acknowledges and agrees that the agreement to forbear
by the Lender hereunder shall not be construed as a waiver or release of any of
the Specified Events of Default (as defined below) or any other Events of
Default under the Loan Agreement or the Other Documents which may exist on the
date hereof or arise hereafter, and all rights and remedies available to the
Lender under the Loan Agreement and the Other Documents, at law or in equity,
are hereby preserved. The term "Specified Events of Default" means,
collectively, the Events of Default which have occurred prior to the Effective
Date as specified on Schedule A attached hereto and made a part hereof.



                                       2
<PAGE>

              (b) Subject to the terms and conditions hereof, on the Effective
Date and continuing to, but not including, the Termination Date (as defined
below) (the "Forbearance Period"), the Lender shall forbear from exercising its
rights and remedies with respect to the Specified Events of Default. The
Termination Date shall mean the earlier of (a) the date that is sixty (60) days
after the Effective Date, and (b) the date of the occurrence of any Event of
Default (other than the Specified Events of Default) including without
limitation any violation of or noncompliance with the terms and conditions of
this Agreement.

         4. Release. Each Borrower hereby releases, waives and forever
relinquishes all claims, demands, obligations, liabilities and causes of action
of whatever kind or nature, whether known or unknown, including, without
limitation, any so-called "lender liability" claims or defenses which it has,
may have, or might assert now or in the future against the Lender and/or its
participants, officers, directors, employees, agents, attorneys, accountants,
consultants, successors and assigns (individually, a "Releasee" and
collectively, the "Releasees"), directly or indirectly, arising out of, based
upon, or in any manner connected with (i) any transaction, event, circumstance,
action, failure to act or occurrence of any sort or type, whether known or
unknown, which occurred, existed, or was taken or permitted prior to the
execution of this Agreement with respect the Liabilities, the Loan Agreement,
the Other Documents or the administration thereof or the obligations created
thereby; (ii) any discussions, commitments, negotiations, conversations or
communications prior to the execution of this Agreement with respect to the
refinancing, restructuring or collection of any of the Liabilities; or (iii) any
thing or matter related to any of the foregoing prior to the execution of this
Agreement. The inclusion of this paragraph in this Agreement, and the execution
of this Agreement by the Lender, does not constitute an acknowledgment or
admission by the Lender of liability for any matter, or a precedent upon which
any liability may be asserted. If any Borrower asserts or commences any claim,
counter-claim, demand, obligation, liability or cause of action in derogation of
the foregoing release or challenges the enforceability of the foregoing release
(in each case, a "Violation"), then the Borrowers jointly and severally agree to
pay, in addition to such other damages as any Releasee may sustain as a result
of such Violation, all attorneys' fees and costs incurred by such Releasee as a
result of such Violation.

         5. Amendments and Modifications.

<PAGE>

                  "'Applicable Margin' shall mean, for (a) Revolving Credit

         Loan A, a percentage equal to 1.25% and (c) Term Loan B, a percentage
         equal to 2.50%."

                  (ii) The Borrower confirms that pursuant to the Loan

         amount equal to Eight Million Five Hundred Thousand Dollars
         ($8,500,000)."

                  (ii) Notwithstanding anything to the contrary contained in the

                  days past the original invoice date or (B) 90 days past the
original due date,
may constitute Eligible Accounts if such Accounts otherwise satisfy the criteria
for Eligible Accounts contained in the Loan Agreement, and (ii) the Borrowers
and Lender agree that, for purposes of the 25% test for cross-aging Accounts
contained in the proviso of clause (iv), Accounts will be cross-aged on a
consolidated basis rather than on an individual Borrower basis (and such
cross-aging shall be based on Accounts aged past the lesser of (A) 120 days from
the original invoice date or (B) 90 days from the original due date).

              (c) Section 12 of the Loan Agreement is amended by adding a new

         Five Hundred Thousand Dollars ($3,500,000) and not more than Four
         Million Five Hundred Thousand Dollars ($4,500,000), which shall
         utilized by Borrowers to repay in full Term Loan B (together with

the Other Documents, and to pay or reimburse the Lender for all reasonable

liens, security interests or other encumbrances other than Permitted Liens. Each
Borrower acknowledges and agrees that nothing herein contained in any way
impairs the Lender's existing rights and priority in the Collateral.

the pendency of this Agreement, all statutes of limitation and similar laws,
rules and equitable theories with respect to the time in which the Lender may
bring any claim or action against any of the Borrowers shall be tolled and that

INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA
WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAW.

              (g) This Agreement may be executed in any number of counterparts,
each of which when so executed and delivered shall be deemed an original, but
all of which counterparts together shall constitute but one and the same
instrument. Execution and delivery by facsimile shall bind each of the parties.

of the Borrowers and the Lender and their respective successors and assigns,
except that no Borrower may assign or transfer its rights or obligations
hereunder without the prior written consent of the Lender.

              (i) Any provision hereof that is prohibited or unenforceable in
any jurisdiction shall be, as to such jurisdiction, ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

              (j) No rights are intended to be created hereunder for the benefit
of any third party donee, creditor or incidental beneficiary.

              (k) The headings of any section or paragraph of this Agreement are
