                  (iii)   license   agreements   (to  the  extent  such  license
         agreements  may be  assigned  without  violating  the terms of any such
         license agreement) with respect to any of the Patents or the Trademarks
         or any other  patent,  trademark,  service mark or any  application  or
         registration  thereof  or any other  trade name or  tradestyle  between
         Mortgagor  and any other  party,  whether  Mortgagor  is a licensor  or
         licensee  under  any  such  license   agreement,   including,   without
         limitation, the licenses listed on Exhibit C attached hereto and hereby
         made  a part  hereof  (all  of the  foregoing  license  agreements  and
         Mortgagor's  rights  thereunder  are  referred to  collectively  as the
         "Licenses"); and

                  (iv) the goodwill of Mortgagor's  business  connected with and
         symbolized by the Trademarks.

         3. Warranties and Representations. Except as disclosed in Exhibits A, B
and C hereto, Mortgagor warrants and represents to Mortgagee that:

                  (i) no Patent,  Trademark or License has been adjudged invalid
         or  unenforceable  nor has any such  Patent,  Trademark or License been
         canceled,  in  whole or in part and each  such  Patent,  Trademark  and
         License is presently subsisting;

                  (ii)  each  Patent,  Trademark  and  License  Material  to the
         Mortgagor's business is valid and enforceable;

                                Exhibit 10.38 - 2




                  (iii)  Mortgagor is the sole and exclusive owner of the entire
         and unencumbered right, title and interest as they may appear in and to
         each  Patent,  Trademark  and  License,  free and  clear of any  liens,
         charges and encumbrances,  including without limitation licenses,  shop
         rights and covenants by Mortgagor not to sue third persons;

                  (iv) Mortgagor has adopted, used and is currently using all of
         the Trademarks;

                  (v) Mortgagor has no notice of any suits or actions  commenced
         or threatened  with  reference to the Patents,  Trademarks or Licenses;
         and

                  (vi)  Mortgagor  has the  unqualified  right  to  execute  and
         deliver this Mortgage and perform its terms.

         4. Restrictions on Future  Agreements.  Mortgagor agrees that until all
Obligations shall have been satisfied in full and the Loan Agreements shall have
been  terminated,  Mortgagor  shall not,  without the prior  written  consent of
Mortgagee,  sell or assign its interest  in, or grant any license or  sublicense
under the Patents,  Trademarks  or Licenses,  or enter into any other  agreement
with  respect to the Patents,  Trademarks  or Licenses,  and  Mortgagor  further
agrees  that it shall not take any  action or permit  any  action to be taken by
others subject to its control,  including licensees,  or fail to take any action
which would affect the  validity of the rights  transferred  to Mortgagee  under
this Mortgage.

         5. New Patents,  Trademarks,  and Licenses.  Mortgagor  represents  and
warrants that the Patents,  Trademarks and Licenses  listed on Exhibits A, B and
C,  respectively,  constitute all of the Patents,  Trademarks,  and Licenses now
owned by Mortgagor. If, before all Obligations shall have been satisfied in full
or before the Loan Agreements have been  terminated,  Mortgagor shall (i) become
aware of any existing Patents, Trademarks or Licenses of which Mortgagor has not
previously  informed  Mortgagee,  (ii)  obtain  rights  to  any  new  patentable
inventions,  Patents,  Trademarks or Licenses,  or (iii) become  entitled to the
benefit of any Patents, Trademarks or Licenses which benefit is not in existence
on the date hereof,  the provisions of this Mortgage  above shall  automatically
apply  thereto and  Mortgagor  shall give to  Mortgagee  prompt  written  notice
thereof.  Mortgagor  hereby  authorizes  Mortgagee  to modify  this  Mortgage by
amending  Exhibits  A, B and C, as  applicable,  to  include  any such  Patents,
Trademarks and Licenses.

         6.  Royalties;  Terms.  The term of the mortgages  granted herein shall
extend  until  the  earlier  of (i) the  expiration  of  each of the  respective
Patents,  Trademarks and Licenses  assigned  hereunder,  and (ii) the payment in
full of all Obligations and the  termination of the Loan  Agreements.  Mortgagor
agrees that upon the occurrence of an Event of Default,  the use by Mortgagee of
all Patents,  Trademarks and Licenses  shall be worldwide,  except as limited by
their terms,  and without any liability  for royalties or other related  charges
from Mortgagee to Mortgagor.

                                Exhibit 10.38 - 3




         7. Grant of License to Mortgagor.  Unless and until an Event of Default
shall have  occurred,  Mortgagee  hereby grants back to Mortgagor the exclusive,
nontransferable  right and license to use the Trademarks in the ordinary  course
of its business, to exercise Mortgagee's rights under the Licenses, and to make,
have made, use and sell the inventions  disclosed and claimed in the Patents for
Mortgagor's own benefit and account and for none other.  Mortgagor agrees not to
sell or assign its  interest  in, or grant any  sublicense  under,  the  license
granted to Mortgagor in this  Section 7,  without the prior  written  consent of
Mortgagee.  From and after the  occurrence  of an Event of Default,  Mortgagor's
license with respect to the Patents,  Trademarks  and Licenses set forth in this
Section 7 shall  terminate  upon receipt by Mortgagor of written  notice of such
termination  from Mortgagee,  and Mortgagee shall have, in addition to all other
rights and  remedies  given it by this  Mortgage,  those  allowed by law and the
rights and  remedies of a secured  party under the  Uniform  Commercial  Code as
enacted in Illinois.

         8. Mortgagee's Right to Inspect. Mortgagee shall have the right, at any
time and from time to time during normal  business hours and prior to payment in
full of all  Obligations  and  termination  of the Loan  Agreements,  to inspect
Mortgagor's  premises and to examine Mortgagor's books,  records and operations,
including,  without limitation,  Mortgagor's quality control processes. Upon the
occurrence  of an  Event of  Default,  Mortgagor  agrees  that  Mortgagee,  or a
conservator  appointed  by  Mortgagee,  shall have the right to  establish  such
additional  product quality controls as Mortgagee,  or said conservator,  in its
sole  judgment,  may deem  necessary  to assure  maintenance  of the  quality of
products sold by Mortgagor under the Trademarks.  The foregoing notwithstanding,
unless and until an Event of Default shall have  occurred,  Mortgagee  agrees to
hold confidential and not disclose or use any information  regarding any Patent,
Trademark or License  unless such  disclosure is required by  applicable  law or
court order.  This  obligation  shall survive the termination of this Agreement,
the  release  of the  mortgage  herein  and such  reassignment  of the  Patents,
Trademarks or Licenses,  as  applicable,  unless such  termination  is due to an
Event of Default.

         9. Release of Mortgage.  This Mortgage is made for collateral  purposes
only.  Upon  payment  in full of all  Obligations  and  termination  of the Loan
Agreements,  Mortgagee  shall  execute  and  deliver  to  Mortgagor  all  deeds,
assignments and other instruments,  and shall take such other actions, as may be
necessary  or  proper  to  re-vest  in  Mortgagor  full  title  to the  Patents,
Trademarks and Licenses,  subject to any disposition thereof which may have been
made by Mortgagee pursuant to the Loan Agreements.

         10. Expenses.  All expenses incurred in connection with the performance
of any of the agreements set forth herein shall be borne by Mortgagor. All fees,
costs and  expenses,  of  whatever  kind or  nature,  including  attorneys'  and
paralegals'  fees and legal  expenses,  incurred by Mortgagee in connection with
the filing or  recording of any  documents  (including  all taxes in  connection
therewith)  in public  offices,  the payment or discharge of any taxes,  counsel
fees, maintenance fees, encumbrances or otherwise in protecting,  maintaining or
preserving the Patents,  Trademarks and Licenses, or in defending or prosecuting
any actions or proceedings arising out of or related to the Patents,  Trademarks
and Licenses, shall be borne by and paid by Mortgagor on demand by Mortgagee and
until so paid  shall be added to the  principal  amount of

                                Exhibit 10.38 - 4




the Obligations and shall bear interest at the rate for Revolving Loans.

         11. Duties of Mortgagor.  Subject to  Mortgagor's  reasonable  business
judgement and in the ordinary  course of Mortgagor's  business,  Mortgagor shall
have the duty (i) to file and  prosecute  diligently  any patent,  trademark  or
service mark  applications  pending as of the date hereof or hereafter until all
Obligations  shall  have  been  paid in full and the Loan  Agreements  have been
terminated, (ii) to make application on unpatented but patentable inventions and
on trademarks  and service  marks,  (iii) to preserve and maintain all rights in
the  Patents,  Trademarks  and  Licenses,  and (iv) to ensure that the  Patents,
Trademarks  and Licenses are and remain  enforceable.  Any expenses  incurred in
connection with Mortgagor's  obligations under this Section 11 shall be borne by
Mortgagor.  Mortgagor shall not abandon any right to file a patent, trademark or
service mark  application,  or abandon any pending  patent  application,  or any
other Patent, Trademark or License without the consent of Mortgagee.

         12.  Mortgagee's  Right to Sue.  After an Event of  Default,  Mortgagee
shall have the right, but shall in no way be obligated, to bring suit in its own
name to enforce the Patents,  Trademarks and Licenses,  and, if Mortgagee  shall
commence any such suit, Mortgagor shall, at the request of Mortgagee, do any and
all lawful acts and execute any and all proper  documents  required by Mortgagee
in aid of such enforcement and Mortgagor shall promptly, upon demand,  reimburse
and indemnify  Mortgagee for all costs and expenses incurred by Mortgagee in the
exercise of its rights under this Section 12.

         13. Waivers. No course of dealing between Mortgagor and Mortgagee,  nor
any failure to exercise, nor any delay in exercising,  on the part of Mortgagee,
any right,  power or  privilege  hereunder  or under the Loan  Agreements  shall
operate as a waiver  thereof;  nor shall any single or partial  exercise  of any
right, power or privilege  hereunder or thereunder preclude any other or further
exercise thereof or the exercise of any other right, power or privilege.

         14. Severability. The provisions of this Mortgage are severable, and if
any clause or provision shall be held invalid and  unenforceable  in whole or in
part in any jurisdiction,  then such invalidity or unenforceability shall affect
only such clause or provision, or part thereof, in such jurisdiction,  and shall
not in any manner affect such clause or provision in any other jurisdiction,  or
any other clause or provision of this Mortgage in any jurisdiction.

         15. Modification.  This Mortgage cannot be altered, amended or modified
in any way, except as specifically  provided in Section 5 hereof or by a writing
signed by the parties hereto.

         16. Cumulative Remedies; Power of Attorney;  Effect on Loan Agreements.
All of Mortgagee's  rights and remedies with respect to the Patents,  Trademarks
and Licenses,  whether  established hereby or by the Loan Agreements,  or by any
other  agreements or by law shall be cumulative and may be exercised  singularly
or concurrently. Mortgagor hereby authorizes Mortgagee upon the occurrence of an
Event of  Default,  to make,  constitute  and  appoint  any  officer or agent of
Mortgagee as Mortgagee may select,  in its sole discretion,  as Mortgagor's true
and lawful  attorney-in-fact,  with power to (i) endorse Mortgagor's name on all
applications,  documents,  papers and  instruments  necessary or  desirable  for
Mortgagee in the

                                Exhibit 10.38 - 5




use of the Patents, Trademarks and Licenses, or (ii) take any other actions with
respect to the Patents,  Trademarks and Licenses as Mortgagee deems to be in the
best  interest  of  Mortgagee,   or  (iii)  grant  or  issue  any  exclusive  or
non-exclusive  license under the Patents,  Trademarks or Licenses to anyone,  or
(iv) assign,  pledge,  convey or otherwise  transfer  title in or dispose of the
Patents,  Trademarks or Licenses to anyone.  Mortgagor  hereby ratifies all that
such attorney shall lawfully do or cause to be done by virtue hereof. This power
of attorney shall be irrevocable  until all Obligations  shall have been paid in
full and the Loan Agreements have been  terminated.  Mortgagor  acknowledges and
agrees that this  Mortgage  is not  intended to limit or restrict in any way the
rights  and  remedies  of  Mortgagee  under the Loan  Agreements  but  rather is
intended to facilitate the exercise of such rights and remedies. Mortgagee shall
have, in addition to all other rights and remedies given it by the terms of this
Mortgage and the Loan Agreements, all rights and remedies allowed by law and the
rights and  remedies of a secured  party under the  Uniform  Commercial  Code as
enacted in Illinois.

         17.  Binding  Effect;  Benefits.  This  Mortgage  shall be binding upon
Mortgagor  and its  respective  successors  and assigns,  and shall inure to the
benefit of Mortgagee, its successors, nominees and assigns.

         18.  Governing Law. This Mortgage shall be governed by and construed in
accordance with the internal laws of the State of Illinois.

         19. Headings.  Paragraph  headings used herein are for convenience only
and shall not modify the provisions which they precede.

         20. Further  Assurances.  Mortgagor  agrees to execute and deliver such
further agreements, instruments and documents, and to perform such further acts,
as Mortgagee  shall  reasonably  request from time to time in order to carry out
the purpose of this Mortgage and agreements set forth herein.

         21. Survival of Representations.  All representations and warranties of
Mortgagor contained in this Mortgage shall survive the execution and delivery of
this Mortgage and shall be remade on the date of each  borrowing  under the Loan
Agreements.
