         2.2. CONDITIONAL ASSIGNMENT. In addition to, and not by way of

during such continuance or (ii) immediately and automatically (without notice or
action of any kind by the Agent) upon an Event of Default for which acceleration

disposition of or foreclosure upon the Collateral pursuant to the Security
Agreement and applicable law (including the transfer or other disposition of the
Collateral by the Assignor to the Agent or its nominee in lieu of foreclosure).

         2.3. SUPPLEMENTAL TO SECURITY AGREEMENT. Pursuant to the Security
Agreement the Assignor has granted to the Agent, for the benefit of the Banks
and the Agent, a continuing security interest in and lien on the Collateral
(including the Pledged Trademarks). The Security Agreement, and all rights and
interests of the Agent in and to the Collateral (including the Pledged
Trademarks) thereunder, are hereby ratified and confirmed in all respects. In no
event shall this Trademark Agreement, the grant, assignment, transfer and
conveyance of the Pledged Trademarks hereunder, or the recordation of this
Trademark Agreement (or any document hereunder) with the PTO, adversely affect

interest of the Agent in the Collateral (including the Pledged Trademarks)

and perfection of such security interest under the Uniform Commercial Code
(including the security interest in the Pledged Marks), or any present or future

connection with the Security Agreement, this Trademark Agreement or the Uniform
Commercial Code. Any and all rights and interests of the Agent in and to the
Pledged Trademarks (and any and all obligations of the Assignor with respect to
the Pledged Trademarks) provided herein, or arising hereunder or in connection
herewith, shall only supplement and be cumulative and in addition to the rights
and interests of the Agent (and the obligations of the Assignor) in, to or with
respect to the Collateral (including the Pledged Trademarks) provided in or
arising under or in connection with the Security Agreement and shall not be in
derogation thereof.

                       6. AFTER-ACQUIRED TRADEMARKS, ETC.
                          ------------------------------

         6.1. AFTER-ACQUIRED TRADEMARKS. If, before the Obligations shall have

or evidence the Agent's interest therein.

         6.2. AMENDMENT TO SCHEDULE. The Assignor authorizes the Agent to modify

each of the Agent and the Banks harmless from any and all costs, damages,
liabilities and expenses that may be incurred by the Agent or any Bank in

and the duty to bring suit or other action in the Assignor's own name to
maintain and enforce the Trademarks, the Trademark Registrations and the
Trademark Rights. The Assignor may require the Agent to join in such suit or
action as necessary to assure the Assignor's ability to bring and maintain any
such suit or action in any proper forum if (but only if) the Agent is completely
satisfied that such joinder will not subject the Agent or any Bank to any risk
of liability. The Assignor shall promptly, upon demand, reimburse and indemnify

the Agent pursuant to this ss.7.3.

         7.4. PROTECTION OF TRADEMARKS, ETC. In general, the Assignor shall take
any and all such actions (including institution and maintenance of suits,
proceedings or actions) as may be necessary or appropriate to properly maintain,
protect, preserve, care for and enforce the Pledged Trademarks. The Assignor

thereof, the Assignor will notify the Agent in writing of the institution of, or
any final adverse determination in, any proceeding in the PTO or any similar
office or agency of the United States or any foreign country, or any court,
regarding the validity of any of the Trademarks or Trademark Registrations or
the Assignor's rights, title or interests in and to the Pledged Trademarks, and
of any event that does or reasonably could materially adversely affect the value
of any of the Pledged Trademarks, the ability of the Assignor or the Agent to
dispose of any of the Pledged Trademarks or the rights and remedies of the Agent
in relation thereto (including but not limited to the levy of any legal process
against any of the Pledged Trademarks).

Documents, those allowed by law and the rights and remedies of a secured party
under the Uniform Commercial Code as enacted in the Commonwealth of

may immediately, without demand of performance and without other notice (except

hereby expressly waived, sell or license at public or private sale or otherwise
realize upon the whole or from time to time any part of the Pledged Trademarks,

<PAGE>
                                       9


or any interest that the Assignor may have therein, and after deducting from the
proceeds of sale or other disposition of the Pledged Trademarks all expenses
incurred by the Agent in attempting to enforce this Trademark Agreement
(including all reasonable expenses for broker's fees and legal services), shall
apply the residue of such proceeds toward the payment of the Obligations as set
forth in or by reference in the Security Agreement. Notice of any sale, license
or other disposition of the Pledged Trademarks shall be given to the Assignor at
least fifteen (15) days before the time that any intended public sale or other
public disposition of the Pledged Trademarks is to be made or after which any
private sale or other private disposition of the Pledged Trademarks may be made,
which the Assignor hereby agrees shall be reasonable notice of such public or
private sale or other disposition. At any such sale or other disposition, the
Agent may, to the extent permitted under applicable law, purchase or license the
whole or any part of the Pledged Trademarks or interests therein sold, licensed
or otherwise disposed of.

                            9. COLLATERAL PROTECTION.
                               ---------------------

         If the Assignor shall fail to do any act that it has covenanted to do
hereunder in the time prescribed herein, or if any representation or warranty of
the Assignor shall be breached, the Agent, in its own name or that of the
Assignor (in the sole discretion of the Agent), may (but shall not be obligated
to) do such act or remedy such breach (or cause such act to be done or such
breach to be remedied), and the Assignor agrees promptly to reimburse the Agent
for any cost or expense incurred by the Agent in so doing.

                             10. POWER OF ATTORNEY.
                                 -----------------

         If any Event of Default shall have occurred and be continuing, the
Assignor does hereby make, constitute and appoint the Agent (and any officer or
agent of the Agent as the Agent may select in its exclusive discretion) as the
Assignor's true and lawful attorney-in-fact, with full power of substitution and
with the power to endorse the Assignor's name on all applications, documents,
papers and instruments necessary for the Agent to use the Pledged Trademarks, or
to grant or issue any exclusive or nonexclusive license of any of the Pledged
Trademarks to any third person, or to take any and all actions necessary for the
Agent to assign, pledge, convey or otherwise transfer title in or dispose of any
of the Pledged Trademarks or any interest of the Assignor therein to any third
person, and, in general, to execute and deliver any instruments or documents and
do all other acts that the Assignor is obligated to execute and do hereunder.
The Assignor hereby ratifies all that such attorney shall lawfully do or cause
to be done by virtue hereof and releases each of the Agent and the Banks from
any claims, liabilities, causes of action or demands arising out of or in
connection with any action taken or omitted to be taken by the Agent under this
power of attorney (except for the Agent's gross negligence or willful
misconduct). This power of attorney is coupled with an interest and shall be
irrevocable for the duration of this Trademark Agreement.

                                --------------------

         This Trademark Agreement is subject to modification only by a writing
signed by the Agent (with the consent of the Majority Banks) and the Assignor,
except as provided in ss.6.2. The Agent shall not be deemed to have waived any
right hereunder unless such waiver shall be in writing and signed by the Agent
and the Majority Banks. A waiver on any one occasion shall not be construed as a
bar to or waiver of any right on any future occasion.

                   19. GOVERNING LAW; CONSENT TO JURISDICTION.
                       --------------------------------------

         THIS TRADEMARK AGREEMENT IS INTENDED TO TAKE EFFECT AS A SEALED
INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE COMMONWEALTH OF MASSACHUSETTS. The Assignor agrees that any suit for the
enforcement of this Trademark Agreement may be brought in the courts of the
Commonwealth of Massachusetts or any federal court sitting therein and consents
to the non-exclusive jurisdiction of such court and to service of process in any
such suit being made upon the Assignor by mail at the address specified by
reference in ss.17 hereof. The Assignor hereby waives any objection that it may
now or hereafter have to the venue of any such suit or any such court or that
such suit is brought in an inconvenient court.

                            20. WAIVER OF JURY TRIAL.
                                --------------------

         THE ASSIGNOR WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY
ACTION OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS TRADEMARK
AGREEMENT, ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH
RIGHTS OR OBLIGATIONS. Except as prohibited by law, the Assignor waives any
right which it may have to claim or recover in any litigation referred to in the
preceding sentence any special, exemplary, punitive or consequential damages or
any damages other than, or in addition to, actual damages. The Assignor (a)
certifies that neither the Agent or any Bank nor any representative, agent or
attorney of the Agent or any Bank has represented, expressly or otherwise, that
the Agent or any Bank would not, in the event of litigation, seek to enforce the
foregoing waivers, and (b) acknowledges that, in entering into the Credit
Agreement and the other Loan Documents to which the Agent or any Bank is a
party, the Agent and the Banks are relying upon, among other things, the waivers
and certifications contained in this ss.20.

                               21. MISCELLANEOUS.
                                   -------------
