officers or agents upon any notes, checks, drafts, money orders, or other
instruments of payment or Collateral that may come into the possession of the
Bank in full or part payment of any amounts owing to the Bank; granting to the

other encumbrances as may attach to the Collateral, may pay for required
insurance on the Collateral and may pay for the maintenance, appraisal or

         3.       COVENANTS. The Grantor further covenants that: (a) Until all
of the Obligations have been satisfied in full, the Grantor will not enter into
any agreement, including without limitation, license agreements, which are
inconsistent with the rights of the Bank under this Rider; and (b) If the
Grantor acquires rights to any new Trademarks, the provisions of this Rider
shall automatically apply thereto and the Grantor shall give the Bank prompt
written notice thereof along with an amended SCHEDULE A, PROVIDED, HOWEVER ,
that notwithstanding anything to the contrary contained in this Agreement, the
Grantor shall have the right to enter into agreements in the ordinary course of
business with respect to the Trademarks

         4.       EXCLUSIVE USE OF TRADEMARK. So long as this Rider is in effect
and so long as the Grantor has not received notice from the Bank that an Event
of Default has occurred under the Loan Documents and that the Bank has elected
to exercise its rights to assignment hereunder, the Grantor shall continue to
have the exclusive right to use the Trademarks and the Bank shall have no right
to use the Trademarks or issue any exclusive or non-exclusive license with
respect thereto, or assign, pledge or otherwise transfer title in the Trademarks
to anyone else. In addition, as long as this Rider is in effect, Bank agrees
that it shall not assign or otherwise transfer the Trademarks in a manner that
causes abandonment of the Trademarks.

         5.       NEGATIVE PLEDGE. The Grantor agrees not to sell, assign or
further encumber its rights and interest in the Trademarks, other than licensing
in the ordinary course of business of products subject to the Trademarks,
without prior written consent of the Bank.

         6.       REMEDIES UPON DEFAULT. (a) Anything herein contained to the
contrary notwithstanding, if and while the Grantor shall be in default hereunder
or an Event of Default exists under the Loan Documents, the Grantor hereby
covenants and agrees that the Bank, as the holder of a security interest under
the Uniform Commercial Code, as now or hereafter in effect in Pennsylvania, may
take such action permitted under the Loan Documents or permitted by law, in its
exclusive discretion, to foreclose upon the Trademarks covered hereby.

         (b)      For such purposes, and in the event of the Grantor's default
hereunder or an Event of Default under the Loan Documents and while such default
or Event of Default exists, the Grantor hereby authorizes and empowers the Bank
to make, constitute and appoint any officer or agent of the Bank as the Bank may
select, in its exclusive discretion, as the Grantor's true and lawful
attorney-in-fact, with the power to endorse the Grantor's name on all
applications, documents, papers and instruments necessary for the Bank to use
the Trademarks or to grant or issue any exclusive or non-exclusive license under
the Trademarks to anyone else, or necessary for the Bank to assign, pledge,
convey or otherwise transfer title in or dispose of the Trademarks to anyone
else. The Grantor hereby ratifies all that such attorney shall lawfully do or
cause to be done by virtue hereof, except for the gross negligence or willful
misconduct of such attorney. This power of attorney shall be irrevocable for the
life of this Rider and the Loan Documents, and until all the Obligations are
satisfied in full.

                                       2

         (c)      The Grantor expressly acknowledges that this Rider shall be
recorded with the Patent and Trademark Office in Washington, D.C.
Contemporaneously herewith, the Grantor shall also execute and deliver to the
Bank such documents as the Bank shall reasonably request to permanently assign
all rights in the Trademarks to the Bank, which documents shall be held by the
Bank until the occurrence of an Event of Default hereunder or under the Loan
Documents. If, and only ii; an Event of Default has occurred and the Borrower
fails to cure such Event of Default within twenty (20) business days after the
date of such occurrence, the Bank may, at its sole option, record such escrowed
documents with the Patent and Trademark Office.

       7.       PROSECUTION OF TRADEMARK APPLICATIONS. (a) Subject to the
terms of the Security Agreement, the Grantor shall have the duty to prosecute
diligently any trademark application with respect to the Trademarks pending as
of the date of this Rider or thereafter, until the Obligations shall have been
satisfied in full, to preserve and maintain all rights in the Trademarks, and
upon reasonable request of the Bank, the Grantor shall make federal application
on registrable but unregistered trademarks belonging to the Grantor. Any
reasonable expenses incurred in connection with such applications shall be borne
by the Grantor. Unless the Grantor discontinues the sale of the goods offered in
connection with a Trademark, the Grantor shall not abandon any Trademark without
the written consent of the Bank.

         (b)      The Grantor shall have the right to bring suit in its own name
to enforce the Trademarks, in which event the Bank may, if the Grantor deems it
necessary or after an Event of Default under the Loan Documents, be joined as a
nominal party to such suit if the Bank shall have been satisfied that it is not
thereby incurring any risk of liability because of such joinder. The Grantor
shall promptly, upon demand, reimburse and indemnify the Bank for all damages,
reasonable costs and reasonable expenses, including attorneys' fees, incurred by
the Bank in the fulfillment of the provisions of this paragraph.

       8.       SUBJECT TO SECURITY AGREEMENT. This Rider shall be subject to
the terms, provisions, and conditions set forth in the Security Agreement and
may not be modified without the written consent of the party against whom
enforcement is being sought.

       9.       INCONSISTENT WITH SECURITY AGREEMENT. All rights and remedies
herein granted to the Bank shall be in addition to any rights and remedies
granted to the Bank under the Loan Documents. In the event of an inconsistency
between this Rider and the Security Agreement, the language of the Security
Agreement shall control. The terms and conditions of the Security Agreement are
hereby incorporated herein by reference.

       10.      TERMINATION OF AGREEMENT. Upon payment and performance of all
Obligations under the Loan Documents, the Bank shall immediately execute and
deliver to the Grantor all documents, and take any and all actions, necessary to
terminate the Bank's security interest in the Trademarks.

       11.      FEES AND EXPENSES. Any and all reasonable fees, costs and
expenses, of whatever kind or nature, including the reasonable attorneys' fees
and legal expenses incurred by the Bank in connection with the preparation of
this Rider and all other documents relating hereto and the consummation of this

connection therewith) in public offices, and the payment or discharge of any

the Trademarks, in each case in accordance with the terms of this Rider, shall
be borne and paid by the Grantor on demand by the Bank and until so paid shall
be added to the principal amount of the Obligations to the Bank and shall bear
interest at the contract rate therefor,

       12.      ADDITIONAL REMEDIES. Upon the occurrence of an Event of
Default under the Loan Documents, the Bank may, without any obligation to do so,
complete any obligation of the Grantor hereunder, in the Grantor's name or in
the Bank's name, but at the Grantor's expense, and the Grantor hereby agrees to
