Term Note(s) are referred to collectively herein as the "Notes"). The term "Loan
Documents" and all other capitalized terms used herein and not defined herein
have the meanings given to them in the Loan Agreement;

         WHEREAS, the Borrower owns, directly or indirectly, all or
substantially all of the equity interest in Guarantor and the Guarantor is

Agreement of even date herewith executed by Guarantor, reference to which is
made for the rights of the Agent for the ratable benefit of the Lenders to

renewals, extensions, forbearances, releases of collateral or other
relinquishments of rights as Lender may deem advisable.

Lenders of the Loan Agreement, and for other good and valuable consideration,

irrevocably guarantees, for the ratable benefit of Lenders and for the ratable
benefit of each and every present and future holder or holders of the Notes (all
herein called the "Lender"), the full and prompt payment to the Lender at
maturity (whether at the stated maturities thereof, or by acceleration or
otherwise) of the present or future indebtedness of the Borrower evidenced by
the Loan Agreement and the Notes, together with all other present or future
obligations and liabilities of the Borrower under and pursuant to the Loan
Documents as the same or any thereof may from time to time be amended, restated
and modified (all of which indebtedness, obligations and liabilities being
herein called the "Indebtedness Hereby Guaranteed") and the full and prompt
performance and observance by the Borrower of all of the warranties, covenants
and agreements provided by the Loan Documents to be performed and observed by
the Borrower (herein called the "Obligations"); and to this end the Guarantor
covenants and agrees to take all such actions necessary to enable the Borrower
to observe and perform and to refrain from taking any action which would prevent
the Borrower from observing and performing each and every Obligation.

         2. CONTINUING GUARANTY. This Guaranty shall be a continuing guaranty,
shall be binding upon the Guarantor, its successors and assigns, and shall
remain in full force and effect, and shall not be discharged, impaired or
affected by (a) the existence or continuance of any obligation on the part of
the Borrower on or with respect to the Indebtedness Hereby Guaranteed, or any
Obligation under the Loan Documents; (b) the power or authority (or any lack
thereof) of the Borrower to issue the Notes or to execute, acknowledge or
deliver any other Loan Document; (c) the validity or invalidity of the Notes or
any other Loan Document; (d) any defense whatsoever that the Borrower may or
might have to the payment of the Indebtedness Hereby Guaranteed or to the
performance or observance of any of the terms, provisions, covenants and
agreements contained in the Notes or other Loan Documents; (e) any limitation or
exculpation of liability on the part of the Borrower; (f) the dissolution of the
Borrower; (g) the transfer by the Borrower of all or any part of the property
referred to in the Loan Documents to any other corporation, person or entity;
(h) any sale, pledge, surrender, indulgence, alteration, substitution, exchange,
change in, additions to, renewals of, extension, modification or other
disposition of any of the Indebtedness Hereby Guaranteed, or any of the
Obligations, all of which the Lender is hereby expressly authorized to make from
time to time without notice to the Guarantor, or to anyone; (i) the acceptance
by the Lender of any security for, or other guarantors upon, all or any part of
the Indebtedness Hereby Guaranteed or Obligations; (j) any failure, neglect or
omission on the part of the Lender to realize or protect any of the Indebtedness
Hereby Guaranteed or any collateral or security therefor, or to exercise any
lien upon or right or appropriation of any moneys, credits or property of the
Borrower toward the liquidation of the Indebtedness Hereby Guaranteed or any
application of payments or credits thereon; (k) any right, claim or offset which
Guarantor may have against the Borrower; or (l) any defense (other than the
payment of the Indebtedness Hereby Guaranteed and performance of the
Obligations, in accordance with its terms) that the Guarantor may or might have
to its respective undertakings, liabilities and obligations hereunder, each and
every such defense being hereby waived by the Guarantor; it being understood and
agreed that this Guaranty, and the undertakings, liabilities and obligations of
the Guarantor hereunder shall not be affected, discharged, impaired or varied by
any act, omission or circumstance whatsoever (whether or not specifically
enumerated above) except the due and punctual payment of the Indebtedness Hereby
Guaranteed and performance of



                                       2
<PAGE>

the Obligations, and then only to the extent thereof; or (m) any understanding
or agreement that any other person, firm or corporation was or is to execute
this Guaranty or the Notes or any of the Loan Documents.

         3. NO OBLIGATION TO PROCEED AGAINST BORROWER. The Lender shall have the
exclusive right to determine how, when and what application of payments and
credits, if any, shall be made on the Indebtedness Hereby Guaranteed or the
Obligations, or any part thereof; and in order to hold the Guarantor liable
hereunder there shall be no obligation on the part of the Lender, or anyone, at
any time, to proceed against the Borrower, its properties or estates, or any one
of them, or to proceed against any other guarantors, or to resort to any
collateral, security, property, liens, or other rights or remedies whatsoever.

         4. BANKRUPTCY OF GUARANTOR. The bankruptcy of Guarantor shall not
terminate this Guaranty, whether or not a claim against the estate of such
bankrupt Guarantor is made, and shall not terminate this Guaranty as to the
estate of the bankrupt Guarantor.

         5. NO OBLIGATION TO PROCEED AGAINST ANY GUARANTOR. The Lender shall
have the right to enforce this Guaranty against Guarantor for and to the full
amount of the Indebtedness Hereby Guaranteed, with or without enforcing or
attempting to enforce the Loan Documents against Borrower or any other guaranty
against any other guarantor, or any security for the obligation of any of them,
and whether or not proceedings or steps are pending or have been taken or have
been concluded to enforce or otherwise realize upon the obligation or security
of the Borrower or any other guarantor, or any of them; and the payment of any
amount or amounts by Guarantor, pursuant to its obligations hereunder, shall not
in any way entitle such Guarantor, either at law, in equity, or otherwise, to
any right, title, or interest (whether by way of subrogation or otherwise) in
and to any of the Indebtedness Hereby Guaranteed, or any principal or interest
payments theretofore, then, or thereafter at any time made by the Borrower or
any other guarantor, or any of them, on the Indebtedness Hereby Guaranteed, or
made by anyone on behalf of the Borrower, or in and to any security therefor,
unless and until the full amount of the Indebtedness Hereby Guaranteed has been
fully paid.

         6. TIME OF ESSENCE. Time is of the essence of this Guaranty and of the
performance of each term, covenant and provision hereof.

         7. WAIVER OF NOTICE. All diligence in collection or protection, and all
presentment, demand, protest and/or notice of dishonor, protest, and of default
and of non-payment and of the creation and existence of any and all of the
Indebtedness Hereby Guaranteed or of performance or non-performance of any
Obligation, and of any security and collateral therefor, and of the acceptance
of this Guaranty, and of any and all extensions of credit and indulgence
hereunder, are expressly waived by the Guarantor.

         8. TRANSFER OF DEBT BY LENDER. The Lender may, without any notice
whatsoever to anyone, sell, assign, or transfer all or any part of the
Indebtedness Hereby Guaranteed, or grant participations in the Indebtedness
Hereby Guaranteed, and in any and every such event, each and every immediate and
successive assignee, transferee, holder of or participant in all or any part of
the Indebtedness Hereby Guaranteed shall have the right to enforce this Guaranty
by suit or otherwise, for the benefit of such assignee, transferee, holder or


                                       3
<PAGE>

participant, as fully as if such assignee, transferee, holder or participant
were herein by name specifically given such rights, powers, and benefits.

         9. SUCCESSORS AND ASSIGNS. This Guaranty, and each and every part
hereof, shall be binding upon the Guarantor, successors and assigns of
Guarantor, and shall inure to the pro rata benefit of each and every future
holder of the Notes or any interest in the Indebtedness Hereby Guaranteed
pursuant to the terms of the Loan Agreement.

         10. DELIVERY OF NOTE. The delivery of the Notes or any other promissory
note evidencing the Indebtedness Hereby Guaranteed for value to any person
shall, without more, constitute conclusive evidence of the acceptance hereof,
and of the reliance hereon by each and every from time to time holder of the
Note or any interest in the Indebtedness Hereby Guaranteed.

         11. MASCULINE, FEMININE, PLURAL. As used herein, the masculine gender
shall include the feminine, and the singular case shall include the plural and
the plural the singular, wherever the same may be applicable.

         12. BANKRUPTCY OF BORROWER. Notwithstanding any modification,
discharge, or extension of the Indebtedness Hereby Guaranteed or any amendment,
modification, stay or cure of the Lender's rights under the Notes, or other Loan
Documents which may occur in any bankruptcy or reorganization case or proceeding
affecting the Borrower, whether permanent or temporary, and whether or not
assented to by the Lender, the Guarantor hereby agrees that it shall be
obligated hereunder to pay the Indebtedness Hereby Guaranteed and discharge the
other Obligations in accordance with the terms of the Notes, and other Loan
Documents and the terms of this Guaranty as in effect on the date hereof.

         Guarantor understands and acknowledges that by virtue of this Guaranty
it has specifically assumed any and all risks of a bankruptcy or reorganization
case or proceeding affecting the Borrower; and, as an example and not by way of
limitation, a subsequent modification of the Notes in any reorganization case
concerning the Borrower shall not affect the obligation of the Guarantor to pay
the indebtedness evidenced by the Note and all other Indebtedness Hereby
Guaranteed in accordance with its original terms.

         13. RETURN OF PAYMENT. Guarantor hereby agrees that if at any time all
or any part of any payment theretofore applied by Lender to any Indebtedness
Hereby Guaranteed is rescinded or returned by Lender for any reason whatsoever
(including, without limitation, the insolvency, bankruptcy, liquidation or
reorganization of any party), the Indebtedness Hereby Guaranteed shall, for the
purposes of this Guaranty, be deemed to have continued in existence to the
extent of such payment, notwithstanding such application by Lender, and this
Guaranty shall continue to be effective or be reinstated, as the case may be, as
to the Indebtedness Hereby Guaranteed, all as though such application by Lender
had not been made.

         14. COSTS AND EXPENSES. In addition to all other amounts payable by
Guarantor hereunder, Guarantor hereby agrees to pay to Lender upon demand any
and all costs and expenses, including court costs and reasonable attorney's fees
which the Lender may incur (a) in enforcing the obligations of the Guarantor
hereunder; or (b) in preparing to collect or



                                       4
<PAGE>

enforce the Indebtedness Hereby Guaranteed and the Obligations or in collecting
or enforcing the same, in each case whether or not suit or action is filed.

         15. PARTIAL INVALIDITY. If any term of this Guaranty, or the
application thereof to a person or circumstance, shall to any extent be declared
invalid or unenforceable, the remainder of this Guaranty, or the application of
such term, to persons or circumstances other than those to which it is invalid
or unenforceable shall not be affected thereby and each term of this Guaranty
shall remain valid and enforceable to the fullest extent permitted by applicable
law. Notwithstanding anything in this Guaranty to the contrary, the right to
recover against the Guarantor under this Guaranty shall not exceed $1 less than
the amount which would render any of the Guarantor's obligations under this
Guaranty void or voidable under applicable law, including fraudulent conveyance
law.

         16. ASSIGNMENT OF GUARANTY. Lender may without prior notice assign this
Guaranty in whole or in part but shall notify Guarantor after such assignment.

         17. SETOFF. In addition to all liens upon, and rights of setoff against
the moneys, securities, or other property of Guarantor given to Lender by law,
Lender shall have a lien upon and a right of setoff against all moneys,
securities, and other property of Guarantor now or hereafter in the possession
of or on deposit with Lender, whether held in a general or special account or
deposit, or for safekeeping or otherwise; and every such lien and right of
setoff may be exercised so long as there is any Existing Default under the Loan
Agreement without demand upon or notice to Guarantor. No lien or right of setoff
shall be deemed to have been waived by any act or conduct on the part of Lender,
or by any neglect to exercise such right of setoff or to enforce such lien, or
by any delay in so doing, and every right of setoff and lien shall continue in
full force and effect until such right of setoff or lien is specifically waived
or released by an instrument in writing executed by Lender.

         18. SUBORDINATION OF DEBT OF BORROWER. Any indebtedness of Borrower now
or hereafter held by Guarantor, whether secured or unsecured, and if secured,
the security for same, is hereby subordinated to the indebtedness of Borrower to
Lender; and, so long as there is any Existing Default under the Loan Agreement,
such indebtedness of Borrower to Guarantor shall be collected, enforced, and
received by Guarantor as trustee for Lenders and be paid over to Lenders on
account of the indebtedness of Borrower to Lenders but without reducing or
affecting in any manner the liability of Guarantor under the other provisions of
this Guaranty.

         19. AUTHORIZATION OF BORROWER'S DEBT. It is not necessary for Lender to
inquire into the authority or powers of Borrower or the officers, directors,
partners, or agents acting or purporting to act on Borrower's behalf, and any
indebtedness made or created in reliance upon the professed exercise of such
powers shall be guaranteed hereunder.

         20. GOVERNING LAW; NO THIRD PARTY RIGHTS. This Guaranty is to be
governed by and construed and interpreted in accordance with the internal Laws
of the State of Illinois applicable to contracts made and to be performed wholly
within such state, without regard to choice or conflicts of law principles. This
Guaranty is solely for the benefit of the Guarantor and Agent and the Lenders
and their respective successors and assigns pursuant to the



                                       5
<PAGE>

terms of the Loan Agreement, and no other person has any right, benefit,
priority or interest under, or because of the existence of, this Guaranty.

         21. WAIVER OF DEFENSES. Guarantor does hereby expressly waive any and
all rights, remedies, benefits, or defenses which might otherwise be available
to a guarantor or surety under the laws of the State of Illinois, and any
defense based upon a claim that Lender's demands or claims against the
undersigned are not compensable because the fair market value of the security
for the Indebtedness Hereby Guaranteed, in its state of completion as of the
date of such demands or claims, was at least equal to the Indebtedness Hereby
Guaranteed.

         22. INCONSISTENCY. To the extent the provisions of this Guaranty
conflict with the provisions of the Loan Agreement, the Loan Agreement shall
govern.

         23. HEADINGS. The headings of this Guaranty are inserted for
convenience of reference only and shall not be applied in construing the
provisions of this Guaranty.

         24. JOINT AND SEVERAL. The agreements, obligations, warranties and
representations or Guarantor hereunder are joint and several if Guarantor is
more than one person or entity, and are independent of the obligations of
Borrower.

         25. CUMULATIVE REMEDIES. The rights and remedies herein provided are
cumulative and may be exercised singly or concurrently, and are not exclusive of
any rights or remedies provided by law.

         26. CHOICE OF FORUM. SUBJECT ONLY TO THE EXCEPTION IN THE NEXT
SENTENCE, GUARANTOR AND AGENT HEREBY AGREE TO THE EXCLUSIVE JURISDICTION OF THE
FEDERAL COURT OF THE NORTHERN DISTRICT OF ILLINOIS AND THE STATE COURTS OF
ILLINOIS LOCATED IN COOK COUNTY AND WAIVES ANY OBJECTION BASED ON VENUE OR FORUM

CONDUCT OF ANY OF THEM IN CONNECTION WITH THIS GUARANTY OR OTHERWISE SHALL BE
HEARD ONLY IN THE COURTS DESCRIBED ABOVE. NOTWITHSTANDING THE FOREGOING: (1)
AGENT SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST GUARANTOR
OR ITS PROPERTY IN ANY COURTS OF ANY OTHER JURISDICTION DEEMED NECESSARY OR

THE COURTS DESCRIBED IN THE IMMEDIATELY PRECEDING SENTENCE MAY HAVE TO BE HEARD
BY A COURT LOCATED OUTSIDE THOSE JURISDICTIONS.

         27. WAIVER OF JURY TRIAL. GUARANTOR AND AGENT HEREBY WAIVE ANY RIGHT TO
TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER
THIS GUARANTY OR ANY OTHER LOAN DOCUMENT, OR (2) IN ANY WAY CONNECTED WITH OR
RELATED OR



                                       6

INCIDENTAL TO THE DEALINGS OF THE GUARANTOR AND AGENT OR EITHER OF THEM IN
RESPECT OF THIS GUARANTY OR ANY OTHER LOAN DOCUMENT, OR THE TRANSACTIONS RELATED

OR A COPY OF THIS GUARANTY WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF
THE GUARANTOR OR AGENT TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

         28. SERVICE OF PROCESS. GUARANTOR HEREBY WAIVES PERSONAL SERVICE OF ANY

MADE BY REGISTERED MAIL (RETURN RECEIPT REQUESTED) DIRECTED TO GUARANTOR AT ITS
ADDRESS SET FORTH ON THE SIGNATURE PAGE HERETO, AND SERVICE SO MADE SHALL BE

IN THE U.S. MAILS; OR AT AGENT'S OPTION, BY SERVICE UPON CT CORPORATION, WHICH
GUARANTOR IRREVOCABLY APPOINTS AS GUARANTOR'S AGENT FOR THE PURPOSE OF ACCEPTING
SERVICE OF PROCESS WITHIN THE STATE OF ILLINOIS. AGENT SHALL PROMPTLY FORWARD BY
REGISTERED MAIL ANY PROCESS SO SERVED UPON SAID AGENT TO GUARANTOR AT ITS
ADDRESS ON THE SIGNATURE PAGES HERETO. NOTHING IN THIS SECTION SHALL AFFECT THE
RIGHT OF AGENT TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

         IN WITNESS WHEREOF, the Guarantor has signed and sealed this Guaranty
on the day and year first written above.
