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

     Debtor hereby represents,  warrants and covenants with and to Secured Party
the following  (all of such  representations,  warranties  and  covenants  being
continuing so long as any of the Obligations are outstanding):

     (a) Debtor shall pay and perform all of the Obligations  according to their
terms.

     (b) All of the existing  Collateral  is valid and  subsisting in full force
and effect,  and Debtor owns the sole,  full and clear  title  thereto,  and the
right  and power to grant  the  security  interest  and  conditional  assignment
granted  hereunder.  Debtor  shall,  at Debtor's  expense,  perform all acts and
execute all  documents  necessary  to maintain the  existence of the  Collateral
consisting of registered Trademarks as registered trademarks and to maintain the
existence of all of the Collateral as valid and subsisting,  including,  without
limitation,  the  filing  of  any  renewal  affidavits  and  applications.   The
Collateral  is  not  subject  to  any  liens,  claims,  mortgages,  assignments,
licenses,  security interests or encumbrances of any nature whatsoever,  except:
(i)  the  security  interests  granted  hereunder  and  pursuant  to the  Credit
Agreement, (ii) the security interests permitted under the Credit Agreement, and
(iii) the licenses permitted under Section 3(e) below.

     (c) Debtor  shall not assign,  sell,  mortgage,  lease,  transfer,  pledge,
hypothecate,  grant a  security  interest  in or lien upon,  encumber,  grant an
exclusive or  non-exclusive  license  relating to the  Collateral,  or otherwise
dispose of any of the Collateral, in each case without the prior written consent
of Secured Party,  which consent shall not be unreasonably  withheld,  except as
otherwise permitted herein or in the Credit Agreement. Nothing in this Agreement
shall be deemed a consent by Secured  Party to any such  action,  except as such
action is expressly permitted hereunder.

     (d) Debtor  shall,  at  Debtor's  expense,  promptly  perform  all acts and
execute  all  documents  requested  at any time by  Secured  Party to  evidence,
perfect,  maintain,  record or enforce the security  interest in and conditional
assignment  of the  Collateral  granted  hereunder or to  otherwise  further the
provisions of this Agreement.  Debtor hereby authorizes Secured Party to execute
and file one or more financing statements (or similar documents) with respect to
the  Collateral,  signed only by Secured  Party or as  otherwise  determined  by
Secured Party. Debtor further authorizes Secured Party to have this Agreement or
any other similar security  agreement filed with the Commissioner of Patents and
Trademarks or any other appropriate federal, state or government office.

     (e) As of the date hereof, Debtor does not have any Trademarks  registered,
or subject to pending  applications,  in the United  States Patent and Trademark
Office or any similar office or agency in the United States,  any State thereof,
any  political  subdivision  thereof or in any other  country,  other than those
described  in Exhibit A hereto and has not granted  any  licenses  with  respect
thereto other than as set forth in Exhibit B hereto.

     (f) Debtor  shall,  concurrently  with the  execution  and delivery of this
Agreement,  execute and deliver to Secured Party five (5) originals of a Special
Power of Attorney in the form of Exhibit C annexed hereto for the implementation
of the  assignment,  sale or other  disposition  of the  Collateral

                                      -3-
<PAGE>

pursuant  to Secured  Party's  exercise  of the rights and  remedies  granted to
Secured Party  hereunder  following the occurrence and during the continuance of
an Event of Default.

     (g)  Secured  Party may,  in its  discretion,  pay any amount or do any act
which Debtor fails to pay or do as required hereunder or as requested by Secured
Party to preserve, defend, protect, maintain, record or enforce the Obligations,
the  Collateral,  or the security  interest and conditional  assignment  granted
hereunder,  including,  but not limited to, all filing or recording fees,  court
costs, collection charges,  attorneys' fees and legal expenses.  Debtor shall be
liable to Secured Party for any such  payment,  which payment shall be deemed an
advance by Secured  Party to Debtor,  shall be payable on demand  together  with
interest at the rate then  applicable to the Obligations set forth in the Credit
Agreement and shall be part of the Obligations secured hereby.

     (h)   Contemporaneously   with  the  filing  of  any  application  for  the
registration  of a Trademark with the United States Patent and Trademark  Office
or any  similar  office or agency in the United  States,  the Debtor  shall give
Secured Party written notice of such action.  If, after the date hereof,  Debtor
shall (i) obtain any  registered  trademark or tradename,  or apply for any such
registration in the United States Patent and Trademark  Office or in any similar
office  or  agency in the  United  States,  any  State  thereof,  any  political
subdivision  thereof or in any other  country,  or (ii)  become the owner of any
trademark  registrations or applications for trademark  registration used in the
United  States or any State  thereof,  political  subdivision  thereof or in any
other  country,  the  provisions of Section 1 hereof shall  automatically  apply
thereto.  Upon the request of Secured Party,  Debtor shall promptly  execute and
deliver  to  Secured  Party any and all  assignments,  agreements,  instruments,
documents and such other papers as may be requested by Secured Party to evidence
the security  interest in and conditional  assignment of such Trademark in favor
of Secured Party.

     (i) Debtor has not abandoned any of the  Trademarks  and Debtor will not do
any act, nor omit to do any act,  whereby the Trademarks  may become  abandoned,
invalidated,  unenforceable,  voided,  or voidable.  Debtor shall notify Secured
Party  immediately  if it  knows or has  reason  to know of any  reason  why any
application,  registration,  or  recording  with respect to the  Trademarks  may
become abandoned, canceled, invalidated, voided, or voidable.

     (j) Debtor shall render any assistance, as Secured Party shall determine is
necessary,  to Secured Party in any  proceeding  before the United States Patent
and  Trademark  Office,  any federal or state  court,  or any similar  office or
agency in the  United  States,  any State  thereof,  any  political  subdivision
thereof or in any other country,  to maintain such  application and registration
of the Trademarks as Debtor's  exclusive property and to protect Secured Party's
interest therein, including, without limitation,  filing of renewals, affidavits
of  use,  affidavits  of  incontestability  and  opposition,  interference,  and
cancellation proceedings.

     (k) To Debtor's actual knowledge,  no material infringement or unauthorized
use presently is being made of any of the Trademarks that would adversely affect
in any material  respect the fair market value of the Collateral or the benefits
of this Agreement granted to Secured Party, including,  without limitation,  the
validity,  priority or perfection of the security interest granted herein or the
remedies of Secured Party hereunder.  Debtor shall promptly notify Secured Party
if Debtor (or any  affiliate  or

                                      -4-
<PAGE>


subsidiary  thereof) learns of any use by any person of any term or design which
infringes on any Trademark or is likely to cause  confusion  with any Trademark.
If requested by Secured  Party,  Debtor,  at Debtor's  expense,  shall join with
Secured Party in such action as Secured Party,  in Secured  Party's  discretion,
may deem advisable for the protection of Secured Party's  interest in and to the
Trademarks.

     (l) Debtor assumes all responsibility and liability arising from its use of
the Trademarks  (and.  prior to the  occurrence  and  continuance of an Event of
Default,  the  use of  the  Trademarks  by  its  licensees)  and  Debtor  hereby
indemnifies  and holds Secured Party harmless from and against any claim,  suit,
loss, damage, or expense (including  attorneys' fees and legal expenses) arising
out of any alleged  defect in any  product  manufactured,  promoted,  or sold by
Debtor (or any affiliate or subsidiary thereof) in connection with any Trademark
or out of the  manufacture,  promotion,  labeling,  sale or advertisement of any
such product by Debtor (or any affiliate or subsidiary  thereof).  The foregoing
indemnity shall survive the payment of the Obligations,  the termination of this
Agreement and the termination or non-renewal of the Credit Agreement.

     (m) Debtor shall  promptly pay Secured  Party for any and all  expenditures
made by Secured Party  pursuant to the  provisions of this  Agreement or for the
defense,  protection or enforcement of the Obligations,  the Collateral,  or the
security interests and conditional assignment granted hereunder,  including, but
not limited to, all filing or recording fees, court costs,  collection  charges,
travel expenses, and attorneys' fees and legal expenses. Such expenditures shall
be payable on demand,  together with interest at the rate then applicable to the
Obligations  set  forth  in the  Credit  Agreements  and  shall  be  part of the
Obligations secured hereby.

     3A. CERTAIN RESPONSIBILITIES OF THE SECURED PARTY
         ---------------------------------------------

     (a)  Except  in its  capacity  as a lender  or an  administrative  agent or
otherwise as a financial  institution  with respect to a financing  transaction,
Secured Party shall not apply for the  registration of or cause the filing of an
application for the  registration of, a trade name,  trademark,  or service mark
which is identical to or confusingly similar to the Trademarks.

     (b) Prior to the time that  Secured  Party has  asserted  its rights  under
Section 5 hereof, if in Debtor's  reasonable  opinion Secured Party's management
of the  Trademarks  has  brought  or has  the  reasonable  likelihood  to  bring
discredit to Debtor or to the Trademarks ("Incorrect Management"),  Debtor shall
have the unilateral right to notify Secured Party in writing to cease and desist
any such use and/or control over the use of the Trademarks,  and within the time
specified  (which time shall be  reasonable,  allowing  for  reasonable  time to
discuss and cure any  Incorrect  Management,  and, if  incurable,  allowing  for
reasonable   time  to  prepare   and/or  file  any  necessary  and   appropriate
documentation) to reassign the Trademark(s) in question to Debtor along with any
licenses granted by Secured Party with respect  thereto.  It is hereby agreed by
Debtor that if this Agreement  were  performed as written,  there would exist no
Incorrect  Management  and that no action (or  inaction)  would need to occur in
order to avoid Incorrect Management.

                                      -5-
<PAGE>

     (c) At such time as Borrower  shall have  indefeasibly  paid in full all of
the Obligations,  this Agreement shall terminate and Secured Party shall execute
and deliver to Debtor all deeds,  assignments  and other  instruments  as may be
necessary or proper to re-vest in Debtor the full title to the Trademarks.

     4. EVENTS OF DEFAULT
        -----------------

     All Obligations shall become immediately due and payable, without notice or
demand,  at the option of Secured  Party,  upon the  occurrence  of any Event of
Default,  as such term is  defined in the  Credit  Agreement  (each an "Event of
Default" hereunder).

     5. RIGHTS AND REMEDIES
        -------------------

     At any time an Event of Default  exists or has occurred and is  continuing,
in addition to all other rights and remedies of Secured Party,  whether provided
under this Agreement, the Credit Agreement, the other Loan Documents, applicable
law or otherwise,  Secured  Party shall have the  following  rights and remedies
which may be exercised  without  notice to, or consent by, Debtor except as such
notice or consent is expressly provided for hereunder:

     (a) Secured  Party may require  that  neither  Debtor nor any  affiliate or
subsidiary of Debtor make any use of the Trademarks or any marks similar thereto
for any purpose whatsoever. Secured Party may make use of any Trademarks for the
sale of goods,  completion  of  work-in-process  or  rendering  of  services  in
connection with enforcing any other security  interest  granted to Secured Party
by Debtor or any  subsidiary  or affiliate of Debtor or for such other reason as
Secured Party may determine.

     (b)  Secured  Party may grant such  license  or  licenses  relating  to the
Collateral for such term or terms, on such  conditions,  and in such manner,  as
Secured Party shall in its discretion deem appropriate. Such license or licenses
may be general,  special or  otherwise,  and may be granted on an  exclusive  or
non-exclusive  basis throughout all or any part of the United States of America,
its territories and possessions, and all foreign countries.

     (c) Secured Party may assign,  sell or otherwise  dispose of the Collateral
or any part thereof,  either with or without special  conditions or stipulations
except  that if notice  to  Debtor of  intended  disposition  of  Collateral  is
required by law, the giving of five (5) days prior  written  notice to Debtor of
any proposed  disposition  shall be deemed  reasonable notice thereof and Debtor
waives any other notice with respect thereto. Secured Party shall have the power
to buy the Collateral or any part thereof, and Secured Party shall also have the
power to execute  assurances and perform all other acts which Secured Party may,
in its discretion, deem appropriate or proper to complete such assignment, sale,
or disposition. In any such event, Debtor shall be liable for any deficiency.

     (d) In addition to the  foregoing,  in order to implement  the  assignment,
sale,  or other  disposition  of any of the  Collateral  pursuant  to the  terms
hereof,  Secured  Party may at any time execute and deliver on behalf of Debtor,
pursuant to the authority granted in the Powers of Attorney described in Section
3(f) hereof,  one or more  instruments  of assignment of the  Trademarks (or any
application,  registration, or recording relating thereto), in form suitable for
filing, recording, or registration. Debtor agrees to pay

                                      -6-
<PAGE>

Secured  Party  on  demand  all  costs  incurred  in any  such  transfer  of the
Collateral,  including, but not limited to, any taxes, fees, and attorneys' fees
and legal  expenses.  Debtor  agrees that  Secured  Party has no  obligation  to
preserve rights to the Trademarks against any other parties.

     (e) Secured Party may first apply the proceeds  actually  received from any
such license,  assignment, sale or other disposition of any of the Collateral to
the costs and expenses thereof, including,  without limitation,  attorneys' fees
and all legal, travel and other expenses which may be incurred by Secured Party.
Thereafter,  Secured  Party  may  apply any  remaining  proceeds  to such of the
Obligations  as Secured  Party may in its  discretion  determine.  Debtor  shall
remain liable to Secured Party for any of the Obligations remaining unpaid after
the  application of such proceeds,  and Debtor shall pay Secured Party on demand
any such unpaid  amount,  together with interest at the rate then  applicable to
the Obligations set forth in the Credit Agreement.

     (f) Debtor shall supply to Secured  Party or to Secured  Party's  designee,
Debtor's  knowledge and expertise  relating to the  manufacture  and sale of the
products and services  bearing the  Trademarks  and Debtor's  customer lists and
other records  relating to the  Trademarks and the  distribution  thereof at any
time an Event of Default exists and is continuing.

     (g) Nothing  contained herein shall be construed as requiring Secured Party
to take any such action at any time. All of Secured Party's rights and remedies,
whether provided under this Agreement, the other Loan Documents, applicable law,
or  otherwise,  shall be  cumulative  and none is  exclusive.  Such  rights  and
remedies may be enforced alternatively, successively, or concurrently.

     (h) Except as set forth in this Agreement,  Secured Party shall not use the
Trademarks.

governed by the internal laws of the State of New York (without giving effect to
principles of conflicts of law).

     (b)  Debtor  and  Secured  Party  irrevocably  consent  and  submit  to the
non-exclusive  jurisdiction  of the  State  of New York  and the  United  States

therein  arising under this  Agreement or any of the other Loan  Documents or in
any way connected or related or incidental to the dealings of Debtor and Secured
Party  in  respect  of  this  Agreement  or  the  other  Loan  Documents  or the
transactions  related  hereto or thereto,  in each case  whether now existing or
thereafter  arising,  and whether in contract,  tort,  equity or otherwise,  and
agree that any dispute with  respect to any such matters  shall be heard only in
the courts  described  above  (except that Secured Party shall have the right to
bring any action or proceeding  against  Debtor or its property in the courts of
any

                                      -7-
<PAGE>

other  jurisdiction  which Secured Party deems necessary or appropriate in order
to realize on the  Collateral or to otherwise  enforce its rights against Debtor
or its property).

     (c) Debtor  hereby waives  personal  service of any and all process upon it
and  consents  that all such  service of process may be made by  certified  mail
(return receipt requested)  directed to its address set forth herein and service
so made shall be deemed to be completed  five (5) days after the same shall have
been so deposited in the U.S. mails,  or, at Secured Party's option,  by service
upon Debtor in any other  manner  provided  under the rules of any such  courts.
Within  thirty (30) days after such  service,  Debtor  shall appear in answer to
such  process,  failing which Debtor shall be deemed in default and judgment may
be entered by Secured Party against Debtor for the amount of the claim and other
relief requested.

     (d) DEBTOR AND THE SECURED PARTY MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY  WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM  BASED
HEREON,  ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER
LOAN DOCUMENTS  CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE
OF  CONDUCT,  COURSE OF  DEALINGS,  STATEMENTS  (WHETHER  VERBAL OR  WRITTEN) OR
ACTIONS OF ANY PARTY.  THIS WAIVER  CONSTITUTES  A MATERIAL  INDUCEMENT  FOR THE
SECURED  PARTY AND THE LENDER  PARTIES TO ACCEPT THIS  AGREEMENT  AND MAKE LOANS
PURSUANT TO THE TERMS OF THE CREDIT AGREEMENT.

     (e) Secured Party shall not have any liability to Debtor  (whether in tort,
contract, equity or otherwise) for losses suffered by Debtor in connection with,
arising  out of, or in any way  related  to the  transactions  or  relationships
contemplated  by this  Agreement,  or any act,  omission or event  occurring  in
connection  herewith,  unless it is  determined  by a final  and  non-appealable
judgment or court order binding on Secured Party that the losses were the result
of acts or omissions constituting gross negligence or willful misconduct. In any
such  litigation,  Secured  Party  shall  be  entitled  to  the  benefit  of the
rebuttable  presumption  that it acted in good  faith and with the  exercise  of
ordinary care in the  performance  by it of the terms of this  Agreement and the
other Loan Documents.

referred to herein or therein  shall be binding  upon Debtor and its  successors
and assigns and inure to the benefit of and be  enforceable by Secured Party and
its successors and assigns.

     (e)  If  any  provision  of  this  Agreement  is  held  to  be  invalid  or
unenforceable,  such  invalidity or  unenforceability  shall not invalidate this
Agreement as a whole, but this Agreement shall be construed as though it did not
contain the  particular  provision held to be invalid or  unenforceable  and the
rights and  obligations  of the parties  shall be construed and enforced only to
such extent as shall be permitted by applicable law.

     (f) Neither  this  Agreement  nor any  provision  hereof  shall be amended,
modified,  waived or  discharged  orally or by course of conduct,  but only by a
written  agreement  signed by an authorized  officer of Secured  Party.  Secured
Party shall not, by any act,  delay,  omission  or  otherwise  be deemed to have
expressly or impliedly  waived any of its rights,  powers and/or remedies unless
such waiver shall be in writing and signed by an  authorized  officer of Secured
Party. Any such waiver shall be enforceable only to the extent  specifically set
forth  therein.  A waiver by Secured Party of any right,  power and/or remedy on
any one occasion shall not be construed as a bar to or waiver of any such right,
power  and/or  remedy which  Secured  Party would  otherwise  have on any future
occasion, whether similar in kind or otherwise.
