material respects as of the Closing Date.  Subject to the provisions of Section
17 hereof, the representations and warranties of Seller contained in this
Section 7 shall survive the Closing for a period of ninety (90) days; provided,
however, that any claim hereunder based upon such representations and
warranties must be made within such ninety (90) day period.

     Section 8.     Representations and Warranties by Purchaser. Purchaser
represents and warrants as follows:

     (a)  Purchaser is an Illinois corporation, validly existing and in good
standing under the laws of the jurisdiction in which it was formed, and has the
full power, authority and legal right to engage in the transactions
contemplated by, and perform and observe the terms and conditions of this
Agreement.

     (b)  This Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by all necessary action on the part of
Purchaser and, upon the assumption that this Agreement constitutes a valid and
binding obligation of Seller, this Agreement constitutes a legal, valid and
binding obligation of Purchaser, enforceable against Purchaser in accordance
with its terms, except as such enforcement may be limited by bankruptcy,
insolvency, reorganization, moratorium and other similar laws affecting the
enforcement of creditors' rights generally, and by general principles of
equity.

     (c)  The execution and delivery of this Agreement and the consummation of
the transactions contemplated hereby do not and will not (i) violate or
conflict with the organizational documents of Purchaser, (ii) violate or
conflict with any Law or any governmental regulation or permit applicable to
Purchaser, (iii) result in a breach of, or constitute a default under, any of
the provisions of any contract or other instrument to which Purchaser is a
party or by which it is bound, which breach or default would prevent or
materially interfere with Purchaser's performance hereunder, (iv) result in the
creation or imposition of any lien, charge or encumbrance pursuant to the terms
of any such contract or other instrument which lien, charge or encumbrance
would prevent or materially interfere with Purchaser's performance hereunder or
(v) to the best of Purchaser's knowledge, violate, conflict with or constitute
a "prohibited transaction" under Section 406 of the Employee Retirement Income
Security Act of 1974, Section 4975 of the Internal Revenue Code of 1986, as
amended, or under any comparable provision of the Internal Revenue Code of
1986, as amended.

     (d)  The execution and delivery of this Agreement by Purchaser do not, and
the performance of this Agreement by Purchaser will not, require the consent or
approval of any public authority.

     (e)  There are no legal actions, suits, arbitrations, or other legal,
administrative or other governmental proceedings pending or, to the knowledge
of Purchaser, threatened against Purchaser that might question the validity of
this Agreement or the consummation of the transactions contemplated hereby.
<PAGE>
     (f)  Purchaser is a principal with respect to the proposed transaction
relating to the Loan, and is not acting as an agent for an undisclosed
unaffiliated principal.

     (g)  The obligations of Purchaser hereunder are not contingent upon
Purchaser's procuring financing to provide funds to pay the Purchase Price to
Seller, and Purchaser has (or will, as of the Closing Date, have) available
funds to enable it to consummate the purchase and sale described herein.

     (h)  Purchaser is not acting on behalf of the Borrower or any of the
Guarantors.

     (i)  Purchaser is a sophisticated buyer with respect to the Loan, has
adequate information concerning the business and financial condition of
Borrower to make an informed decision regarding the purchase of the Loan and
has independently and without reliance upon Seller, and based on such
information as Purchaser has deemed appropriate, made its own analysis and
decision to enter into this Agreement.

     (j)  Without implying that the Loan constitutes a "security" within the
meaning of any applicable securities laws, Purchaser is not purchasing the Loan
with a view to resale or distribution in a manner that would violate applicable
securities laws.

     All warranties and representations of Purchaser in this Section 8 are true
and correct in all material respects as of the date hereof, and shall continue
to be true and correct in all material respects as of the Closing Date.
Subject to the provisions of Section 17 hereof, the representations and
warranties of Purchaser contained in Sections 8(f), 8(i) and 8(j) shall survive
the Closing.  Subject to the provisions of Section 17 hereof, the remaining
representations and warranties of Purchaser contained in this Section 17 shall
survive the Closing for a period of ninety (90) days; provided, however, that
any claim hereunder based upon such representations and warranties must be made
within such ninety (90) day period.

     Section 9.     Covenants of Seller.  (a) Seller shall not, between the
date hereof and the Closing Date, take any affirmative action, or expressly
consent to any action, which would adversely affect the priority of the lien of
the Mortgage.

     (b)  Seller shall not, between the date hereof and the Closing Date,

          (i)  materially modify, waive or amend the terms of any of the Loan
Documents;

          (ii) foreclose or accept a deed-in-lieu of foreclosure with respect
to the Loan;

          (iii)     grant any consents contemplated in the Loan Documents
without Purchaser's consent, which shall not be unreasonably, withheld,
conditioned or delayed (if Purchaser shall fail to respond to Seller's request
for such a consent for a period of three (3) Business Days, such failure to
respond shall be deemed to constitute Purchaser's consent to such matter);
<PAGE>
          (iv) compromise or settle claims of any kind with respect to the
Loan;

          (v)  sell or enter into an agreement to sell all or any portion of
the Loan or interest therein;

          (vi) release any Borrower or Guarantor or any portion of the
Property; or

          (vii)     increase the principal amount outstanding under any of the
Notes or increase the amount of the debt secured by any of the Mortgages;
provided, however, that Seller may make any advances which it may be required
to make under the Loan Documents and, at Seller's option, Seller may make
advances after obtaining Purchaser's prior written approval (which shall not be
unreasonably withheld, delayed or conditioned and which shall be deemed given
if Purchaser fails to respond to Seller within 24 hours of any written request
for approval) to pay costs and expenses incurred to protect and preserve the
Property and its rights and security under the Loan Documents, including,
without limitation, (A) taxes, charges or assessments that may be imposed by
law upon the Property, (B) premiums on insurance policies covering the
Property, (C) expenses incurred in upholding the lien or enforceability of a
Mortgage or any other Loan Document, (D) utilities, security and maintenance
costs with respect to the Property and (E) any other amount, cost or expense
which Seller is permitted or required to expend pursuant to the Loan Documents
or as otherwise may be required under the Loan Documents or pursuant to
requirements of Law.  Seller shall provide Purchaser with notice of any such
advances made after the date hereof.

     (c)  Between the date hereof and the Closing Date, Seller shall continue
to service the Loan, the Borrower and any Guarantor in accordance with its
prior practices and as it would in the ordinary course of its business.

     (d)  From and after the Closing Date, if Seller shall receive any payment
from a Borrower, any Guarantor or other party on account of an obligation or
liability arising under the Loan Documents which prior to the Closing Date
would have inured to Seller's benefit, then Seller shall accept such payment on
behalf of Purchaser and, subject to the provisions of Section 17 hereof, shall
promptly remit same to Purchaser.

     (e)  From and after the Closing Date, Seller shall cooperate with
Purchaser in connection with the delivery of notices to Borrowers and
Guarantors and the substitution of Purchaser in any ongoing litigation to
collect the Loan or to enforce the Loan Documents, including, without
limitation, providing such documentation, witnesses and information which
Seller possesses and which may be reasonably requested by Purchaser; provided,
however, that Seller shall not be required to incur any cost or expense in
connection therewith for which Purchaser shall not agree to indemnify Seller.

     (f)  Seller shall use its best efforts to obtain and deliver to Purchaser
prior to the Closing (i) the Borrower Estoppel, and (ii) an estoppel
certificate from the holder of the Prior Mortgage certifying as to the amount
of the unpaid principal balance of the Prior Mortgage Loan and that no defaults
<PAGE>
exist under the Prior Mortgage Loan; provided, however, that Seller shall not
be obligated to incur any material cost or expense in connection therewith.

     Section 10.    Covenants of Purchaser.  From and after the date hereof
until the Closing Date, (i) Purchaser shall not contact the Borrower or any
Guarantor regarding the Loan or the Property, (ii) Purchaser shall not take any
action with respect to the Borrower or any Guarantor, the Loan or the Loan
Documents which would have the effect of impairing or diminishing the value
thereof or the priority of the Mortgage, and (iii) Purchaser shall deliver to
Seller copies of all notices given or received by Purchaser in connection with
the Loan.

     Section 11.    Adjustments.  The following (each an "Adjustment") shall be
apportioned at the Closing as of the close of business on the day immediately
preceding the Closing Date:

          (a)  Accrued Interest as of the close of business on the day
immediately preceding the Closing Date shall be calculated and shall constitute
an Adjustment due Seller; and

          (b)  The following advances shall be calculated and shall constitute
an Adjustment due Seller:

               (i)  Any advances which Seller may have made in accordance with
its obligations under the Loan Documents or pursuant to any requirement of any
applicable Laws; or

               (ii) Any advances which Seller may have elected to make to pay
costs and expenses incurred to protect and preserve the Property and its rights
and security under the Loan Documents from and after the Pricing Date through
the close of business on the day immediately preceding the Closing Date,
including, without limitation, (A) taxes, charges or assessments that may be
imposed by law upon the Property, (B) premiums on insurance policies covering
the Property, (C) expenses incurred in upholding the lien or enforceability of
a Mortgage or any other Loan Document, (D) utilities, security and maintenance
costs with respect to the Property, and (E) any other amount, cost or expense
which Seller is permitted or required to expend pursuant to the Loan Documents.

          (c)  Contingent Interest based on the income or cash flow of the
Borrower for the year in which the Closing shall occur shall be prorated on a
per diem basis based on the Contingent Interest paid by the Borrower during the
immediately preceding year, and Seller's pro rata share of such Contingent
Interest shall constitute an Adjustment due Seller.  Such proration shall be
final and shall not be recalculated when the actual Contingent Interest for
such year shall be ascertained.

     Section 12.    Condemnation and Destruction. (a)  If, prior to the Closing
Date, all or any significant portion (as defined in this Section) of the
Property is taken by eminent domain (or, if prior to the Closing Date, any
eminent domain proceeding with respect to any significant portion of the
Property has been commenced or Seller has received written notice threatening
to commence any such eminent domain proceeding), Seller shall notify Purchaser
<PAGE>
thereof promptly after obtaining knowledge thereof and either Purchaser or
Seller shall have the right to terminate this Agreement, which termination
shall be effected by giving notice to the other not later than ten (10) days
after the giving of Seller's notice. For the purposes hereof, a "significant
portion" of the Property shall mean such a portion of the Property as shall
have a value, as reasonably determined by Seller, in excess of ten (10%)
percent of the Purchase Price.  If either party elects to terminate this
Agreement as aforesaid, the provisions of Section 16(b) shall apply.  If
neither Seller nor Purchaser elects to terminate this Agreement as aforesaid,
or if an "insignificant portion" (i.e., anything other than a significant
portion) of the Property is taken by eminent domain (or becomes the subject of
a pending taking), there shall be no abatement of the Purchase Price and Seller
shall assign to Purchaser (without recourse) at the Closing the rights of
Seller to the awards theretofore received, if any, for the taking, and
Purchaser shall be entitled to all rights of Seller under the Loan Documents,
if any, to receive and keep all awards for the taking of the Property or such
portion thereof.

     (b)  If, prior to the Closing Date, a material part (as defined in this
Section) of the Property is destroyed or damaged by fire or other casualty,
Seller shall promptly notify Purchaser thereof and either Purchaser or Seller
shall have the right to terminate this Agreement, which termination shall be
effected by giving notice to the other not later than ten (10) days after the
giving of Seller's notice.  For the purposes hereof, a "material part" of the
Property shall mean a part of the Property as shall have a value, as reasonably
determined by Seller, in excess of ten (10%) percent of the Purchase Price.  If
either party elects to terminate this Agreement as aforesaid, the provisions of
Section 16(b) shall apply.  If neither Seller nor Purchaser elects to terminate
this Agreement as aforesaid, or if there is damage to or destruction of an
"immaterial part" (i.e., anything other than a material part) of the Property
by fire or other casualty, there shall be no abatement of the Purchase Price
and Seller shall assign to Purchaser (without recourse) at the Closing the
rights of Seller to any insurance proceeds theretofore received, if any, with
respect to such damage or destruction, and Purchaser shall be entitled to all
rights of Seller under the Loan Documents, if any, to receive and keep any
insurance proceeds payable upon the occurrence of any such casualty.

     Section 13.    Time of the Essence.  Purchaser and Seller acknowledge and
agree that each and every one of the dates, time periods and time limitations
set forth in this Agreement shall be of the essence of this Agreement as
against Purchaser and Seller.

     Section 14.    Title Examination, Diligence Fees.  All premiums and fees
for title examination and title insurance or any other report, study, survey or
diligence research obtained by Purchaser, if any, and all related charges in
connection therewith shall be paid prior to or at the Closing by Purchaser.

     Section 15.    Broker.  (a) Seller represents and warrants to Purchaser
that it has not hired, retained or dealt with any broker or finder in
connection with the negotiation, execution or delivery of this Agreement or the
transactions contemplated hereby, except Meenan, McDevitt & Company and Creamer
Realty Consultants.  Seller will indemnify Purchaser against all Losses arising
out of any claim that the aforesaid representation and warranty is untrue.
<PAGE>
     (b)  Purchaser represents and warrants to Seller that it has not hired,
retained or dealt with any broker or finder in connection with the negotiation,
execution or delivery of this Agreement or the transactions contemplated
hereby.  Purchaser will indemnity Seller against all Losses arising out of any
claim that the aforesaid representation and warranty is untrue.

     (c)  The provisions of this Section shall survive the Closing and any
termination of this Agreement.

     Section 16.    Remedies.  (a) If Purchaser shall default under this
Agreement, the parties hereto agree that the damages that Seller shall sustain
as a result thereof shall be substantial but shall be difficult to ascertain.
Notwithstanding anything contained herein to the contrary, the parties hereto
therefore agree that if, subject to the conditions contained herein, Purchaser
fails to perform all of the terms, covenants, conditions and agreements to be
performed by it hereunder whether at or prior to the Closing, Seller may retain
the Deposit as and for liquidated damages, and thereafter neither Seller nor
Purchaser shall have any further liability or obligation hereunder, except for
such liabilities or obligations which are specifically stated herein to survive
the termination of this Agreement.

     (b)  If on the Closing Date Seller shall be unable to perform its
obligations or to satisfy any condition applicable to Seller hereunder in
accordance with the provisions of this Agreement or title to the Property shall
not be in accordance with this Agreement and this Agreement shall be terminated
in accordance with its terms as a result thereof, the sole liability of Seller
shall be to direct Escrow Agent to return the Deposit to Purchaser, and, upon
such return, this Agreement shall be deemed terminated and neither Seller nor
Purchaser shall have any further liability or obligation hereunder, except for
such liabilities or obligations as are specifically stated to survive the
termination of this Agreement.

     (c)  Notwithstanding anything contained herein to the contrary, if Seller
shall intentionally default in the performance of its obligation to transfer
the Property hereunder, Purchaser shall be entitled to sue for specific
performance of this Agreement.  Purchaser shall not have any right to sue for
or to collect damages, including, without limitation, punitive damages, from
Seller based upon any such intentional default by Seller.

     (d)  If, pursuant to the terms, conditions and provisions hereof,
Purchaser or Seller is not obligated to purchase and close with respect to the
Loan, then upon Purchaser's or Seller's notice to the other with respect
thereto terminating this Agreement, Seller and Purchaser shall direct Escrow
Agent to disburse the Deposit to Purchaser and, upon such return, this
Agreement shall be deemed terminated and neither Seller nor Purchaser shall
have any further liability or obligation hereunder, except for such liabilities
or obligations as are specifically stated to survive the termination of this
Agreement.
<PAGE>
     Section 17.    Indemnification.

     (a)  Subject to the limitations set forth in this Section 17, from and
after the Closing, Seller shall save, defend and indemnify the Purchaser
Indemnified Persons against and hold them harmless from any and all Losses (but
not exceeding aggregate Losses in excess of $100,000) imposed upon or incurred
by Purchaser Indemnified Persons, directly or indirectly, arising out of the
untruthfulness, inaccuracy or breach of any representation or warranty of
Seller contained in this Agreement or the breach of any agreement or covenant
of Seller contained in this Agreement, excluding any such Losses which shall
have been caused by the intentional misconduct of the Purchaser Indemnified
Persons.

     (b)  Subject to the limitations set forth in this Section 17, from and
after the Closing, Purchaser shall save, defend and indemnify the Seller
Indemnified Persons against and hold them harmless from any and all Losses
imposed upon or incurred by any Seller Indemnified Persons, directly or
indirectly, arising out of (i) the untruthfulness, inaccuracy or breach of any
representation or warranty of Purchaser contained in this Agreement; (ii) the
breach of any agreement or covenant of Purchaser contained in this Agreement;
(iii) Purchaser's failure to perform any of Sellers' obligations under the Loan
Documents which first arise or accrue from and after the Closing; or (iv) the
ownership of the Loan or the Loan Documents by Purchaser after the Closing
Date, excluding any such Losses which shall have been caused by the intentional
misconduct of the Seller Indemnified Persons.  With the exception of (i) Losses
which shall have been caused by the intentional misconduct of the Seller
Indemnified Persons, or (ii) Losses for which Seller is required to indemnify
any Purchaser Indemnified Person pursuant to this Section 17, Purchaser hereby
releases and forever discharges the Seller Indemnified Persons from all
damages, losses, liabilities, obligations, penalties, claims, litigations,
demands, defenses, judgments, suits, proceedings, costs, disbursements or
expenses of any kind or nature sustained, suffered or incurred by any Purchaser
Indemnified Person in connection with or related to the Loan or the Loan
Documents.

     (c)  Each party's right of indemnification hereunder shall be that party's
sole contractual remedy with respect to any claims arising out of or in any way
related to the matters covered by this Agreement from and after the Closing and
shall be in lieu of any other remedy it may otherwise have at law, in equity or
otherwise.

     (d)  The obligations and liabilities of an Indemnifying Person with
respect to Losses resulting from the assertion of liability by third parties
(each, a "Third Party Claim") shall be subject to the following terms and
conditions:

          (i)  The Indemnified Persons shall give prompt written notice (each,
a "Notice of Claim") to the Indemnifying Person of any Third Party Claim which
might give rise to any Loss by the Indemnified Persons, stating the nature and
basis of said Third Party Claim, and the amount thereof to the extent known.
Each Notice of Claim shall be accompanied by copies of all relevant
documentation with respect to such Third Party Claim, including, without
limitation, any summons, complaint or other pleading which may have been served
or written demand or other document or instrument.
<PAGE>
          (ii) If the Indemnifying Person shall acknowledge in writing its
obligation to indemnify the Indemnified Persons, subject to the terms and
conditions of this Agreement, against such Third Party Claim, then the
Indemnifying Person shall have the right to assume the defense of such Third
Party Claim at its own expense and by its own counsel (reasonably satisfactory
to the Indemnified Persons).

          (iii)     If the Indemnifying Person shall assume the defense of a
Third Party Claim in accordance with this Agreement, the Indemnifying Person
shall not be responsible for any legal or other defense costs subsequently
incurred by the Indemnified Persons in connection with the defense thereof.  If
the Indemnifying Person does not exercise its right to assume the defense of
such a Third Party Claim, then the Indemnified Persons may assume such defense
and the costs, expenses and reasonable attorneys' fees incurred by them shall
continue to constitute Losses hereunder.

          (iv) Anything contained herein to the contrary notwithstanding,
neither the Indemnifying Person nor the Indemnified Persons shall admit any
liability with respect to, or settle, compromise or discharge, any Third Party
Claim without the written consent of the other, which consent shall not be
unreasonably withheld.  In addition, each of the Indemnifying Person and the
Indemnified Persons shall cooperate and act in a reasonable and good faith
manner to minimize Losses relating to any Third Party Claim.

     (e)  The provisions of this Section 17 shall survive the Closing.

address or addresses shall only be effective upon receipt.

     Section 19.    Miscellaneous Provision.  (a) The acceptance of the Closing
Documents referenced in Section 6 by Purchaser and Seller shall be deemed an
acknowledgment by Purchaser and Seller that the other has fully complied with
all of its obligations hereunder and that such party is discharged there from
and that such party shall have no further obligation or liability with respect
to any of the agreements made by it in this Agreement, except for those
provisions of this Agreement which expressly provide that any such obligation
of such obligation of such party shall survive the Closing.

     (b)  Each of Seller and Purchaser agrees that it will continue to be bound
by the terms, covenants and conditions of that certain Confidentiality
Agreement, dated as of October 4, 1996 the terms of which shall continue in
full force and effect during the effectiveness of this Agreement and subsequent
to any Closing hereunder or the termination hereof.  Seller agrees to treat the
terms and provisions of this Agreement, as they relate to the Purchase Price
paid by Purchaser and to any other economic terms of this Agreement, as
confidential, and will not disclose any of such terms to any third party,
including but not limited to the Borrower, but excluding Seller's officers,
employees, advisors, attorneys and consultants who have a need to know the same
<PAGE>
in connection with the performance of Seller's obligations under this
Agreement, except to the extent that such disclosure is compelled pursuant to
any judicial order or is required to be disclosed pursuant to any law or
regulation applicable to Seller. The terms of this Section 19(b) shall continue
in full force and effect during the effectiveness of this Agreement and
subsequent to any Closing hereunder or the termination hereof.

     (c)  On or prior to the Closing Date, Purchaser shall not have the right
to assign its rights hereunder, in whole or in part, without the prior written
consent of Seller.  Any assignment on or prior to the Closing Date without such
prior written consent shall be deemed null and void.  Notwithstanding the
foregoing, Purchaser may assign this Agreement on or prior to the Closing Date
to an affiliate (as defined in the Securities Act of 1933) and to any lender
providing financing to Purchaser or such affiliate to consummate the
transactions contemplated herein; provided, however, that if any such
assignment shall occur or if Purchaser shall assign its rights hereunder after
the Closing Date, Purchaser shall remain liable for all obligations of
Purchaser under this Agreement.  Subject to and without limiting the preceding
two sentences, this Agreement shall be binding upon and inure to the benefit of
the parties hereto and their respective successors and assigns.

     (d)  This Agreement does not constitute an offer to sell and shall not
bind the parties hereto unless and until each elects to be bound hereby by
executing and delivering to the other an executed original counterpart hereof.

     (e)  If any term or provision of this Agreement or the application thereof
to any persons or circumstances shall, to any extent, be invalid or
unenforceable, the remainder of this Agreement or the application of such term
or provision to persons or circumstances other than those as to which it is
held invalid or unenforceable shall not be affected thereby, and each term and
provision of this Agreement shall be valid and enforceable to the fullest
extent permitted by law.

     (f)  This Agreement, together with the Escrow Agreement and the Schedules
and Exhibits hereto and thereto, constitute the entire agreement of the parties
regarding the subject matter of this Agreement and the Escrow Agreement, and
all prior or contemporaneous agreements, understandings, representations and
statements, oral or written, are hereby merged herein.

     (g)  The parties agree to mutually execute and deliver to each other, at,
and, from time to time after, the Closing, such other and further documents as
may be reasonably required by counsel for the parties to carry into effect the
purposes and intents of this Agreement, provided such documents do not impose
any material obligations upon any party hereunder except as set forth in this
Agreement.

     (h)  This Agreement may not be modified, amended, altered or supplemented
except by written agreement executed and delivered by Purchaser and Seller.
This Agreement may be executed in any number of counterparts and by different
parties hereto in separate counterparts, each of which when so executed shall
be deemed to be an original, and all of which when so executed shall be deemed
to be an original, and all of which taken together shall constitute one and the
<PAGE>
same agreement. Delivery of an executed counterpart of a signature page to this
Agreement by telecopier shall be effective as delivery of a manually executed
counterpart of this Agreement.  Any delivery of a counterpart signature by
telecopier shall, however, be promptly followed by delivery of a manually
executed counterpart.

     (i)  This Agreement shall be governed by and construed in accordance with
the laws of the State of Illinois applicable to agreements made and to be
performed wholly within such State.

     (j)  All Schedules and Exhibits referred to in this Agreement are
incorporated herein and made a part hereof as fully as if set forth herein.

     (k)  The failure of any party hereto to enforce at any time any of the
provisions of this Agreement shall in no way be construed as a waiver of any of
such provisions, or the right of any party thereafter to enforce each and every
such provision.  No waiver of any breach of this Agreement shall be held to be
a waiver of any other or subsequent breach.

     (l)  Each party to this Agreement shall bear the costs of its own
attorneys' fees and expenses in the preparation, negotiation and execution of
this Agreement.  Purchaser shall pay any transfer, conveyance, real property
transfer or gains, mortgage or mortgage recording, sales, use, value added,
stock or note transfer and stamp taxes, any recording, registration or other
similar taxes, expenses or fees and any penalties, interest and fees thereon,
imposed by any taxing authority, recording officer or register, or other
governmental authority in connection with the transactions contemplated herein.

     (m)  The Article and Section headings used herein are for reference
purposes only and do not control or affect the meaning or interpretation of any
term or provision hereof.  All references in this Agreement to Sections,
paragraphs, Exhibits and Schedules are to the Sections and paragraphs hereof
and the Exhibits and Schedules annexed hereto.

     (n)  The representations, warranties and agreements of the parties
contained herein are intended solely for the benefit of the parties to whom
such representation, warranties or agreements are made and their permitted
assigns, shall confer no rights hereunder, whether legal or equitable, in any
other party, and no other party shall be entitled to rely thereon.

     (o)  Seller and Purchaser each hereby irrevocably submits to the
jurisdiction of any State or Federal court sitting in the County of Cook and
State of Illinois over any action or proceeding arising out of or relating to
