office, to record the Deed.  Seller and Purchaser shall each pay their
respective attorneys' fees.

5.   CONDITION OF TITLE.

     5.1.  If, prior to "Closing" (as hereinafter defined), a date-down to the
Title Commitment or the Updated Survey discloses any new Unpermitted Exception,
Seller shall have thirty (30) days from the date of the date-down to the Title
Commitment or the Updated Survey, as applicable, at Seller's expense, to (i)
bond over, cure and/or have any Unpermitted Exceptions which, in the aggregate,
do not exceed $250,000.00 (a "Minor Unpermitted Exception"), removed from the
Title Commitment or to have the Title Insurer commit to insure against loss or
damage that may be occasioned by such Unpermitted Exceptions, or (ii) have the
right, but not the obligation, to bond over, cure and/or have any Unpermitted
Exceptions which, in the aggregate, equal or exceed $250,000.00, removed from
the Title Commitment or to have the Title Insurer commit to insure against loss
or damage that may be occasioned by such Unpermitted Exceptions.  In such
event, the time of Closing shall be delayed, if necessary, to give effect to
said aforementioned time periods.  If Seller fails to cure or have said
Unpermitted Exception removed or have the Title Insurer commit to insure as
specified above within said thirty (30) day period or if Seller elects not to
exercise its rights under  (ii)  in the preceding sentence, Purchaser may
terminate this Agreement upon notice to Seller within five (5) days after the
expiration of said thirty (30) day period; provided, however, and
notwithstanding anything contained herein to the contrary, if the Unpermitted
Exception which gives rise to Purchaser's right to terminate was recorded
against the Property as a result of the affirmative, willful action of Seller
(and not by any unrelated third party) or if Seller is able to bond over, cure
or remove a Minor Unpermitted Exception for a cost not to exceed $250,000 or
the Title Insurer is willing to insure over a Minor Unpermitted Exception for a
cost not to exceed $250,000 in accordance with the terms hereof and Seller
fails to expend said funds in either case, then Purchaser shall have the
additional rights contained in Paragraph 11 hereof.  Absent notice from
Purchaser to Seller in accordance with the preceding sentence, Purchaser shall
be deemed to have elected to take title subject to said Unpermitted Exception.
If Purchaser terminates this Agreement in accordance with the terms of this
Paragraph 5.1, this Agreement shall become null and void without further action
of the parties and all Earnest Money theretofore deposited into the escrow by
Purchaser together with any interest accrued thereon, shall be returned to
Purchaser, and neither party shall have any further liability to the other,
except for Purchaser's obligation to indemnify Seller and restore the Property,
as more fully set forth in Paragraph 7.
<PAGE>
     5.2.  Seller agrees to convey fee simple title to the Property to
Purchaser by a Deed C (the "Deed") in recordable form subject only to the
Permitted Exceptions and any Unpermitted Exceptions waived by Purchaser.

6.   CONDEMNATION, EMINENT DOMAIN, DAMAGE AND CASUALTY.

     6.1.  Except as provided in the indemnity provisions contained in
Paragraph 7.1 of this Agreement, Seller shall bear all risk of loss with
respect to the Property up to the earlier of the dates upon which either
possession or title is transferred to Purchaser in accordance with this
Agreement.  Notwithstanding the foregoing, in the event of damage to the
Property by fire or other casualty prior to the Closing Date, repair of which
would cost less than or equal to $100,000.00 (as determined by Seller in good
faith) Purchaser shall not have the right to terminate its obligations under
this Agreement by reason thereof, but Seller shall have the right to elect to
either repair and restore the Property (in which case the Closing Date shall be
extended until completion of such restoration) or to assign and transfer to
Purchaser on the Closing Date all of Seller's right, title and interest in and
to all insurance proceeds paid or payable to Seller on account of such fire or
casualty.  Seller shall promptly notify Purchaser in writing of any such fire
or other casualty and Seller's determination of the cost to repair the damage
caused thereby.  In the event of damage to the Property by fire or other
casualty prior to the Closing Date, repair of which would cost in excess of
$100,000.00 (as determined by Seller in good faith), then this Agreement may be
terminated at the option of Purchaser, which option shall be exercised, if at
all, by Purchaser's written notice thereof to Seller within ten (10) business
days after Purchaser receives written notice of such fire or other casualty and
Seller's determination of the amount of such damages, or prior to expiration of
the Due Diligence Period, whichever is later and upon the exercise of such
option by Purchaser this Agreement shall become null and void, the Earnest
Money deposited by Purchaser shall be returned to Purchaser together with
interest thereon, and neither party shall have any further liability or
obligations hereunder.  In the event that Purchaser does not exercise the
option set forth in the preceding sentence, the Closing shall take place on the
Closing Date and Seller shall assign and transfer to Purchaser on the Closing
Date all of Seller's right, title and interest in and to all insurance proceeds
paid or payable to Seller on account of the fire or casualty, and Purchaser
shall receive a credit against the Purchase Price equal to the amount of any
applicable deductible.

     6.2.  If between the date of this Agreement and the Closing Date, any
condemnation or eminent domain proceedings are initiated which might result in
the taking of any part of the Property or the taking or closing of any right of
access to the Property, Seller shall immediately notify Purchaser of such
occurrence.  In the event that the taking of any part of the Property shall, in
Purchaser's reasonable opinion: (i) materially impair access to the Property;
(ii) cause any material non-compliance with any applicable law, ordinance, rule
or regulation of any federal, state or local authority or governmental agencies
having jurisdiction over the Property or any portion thereof; or (iii)
materially and adversely impair the use of the Property as it is currently
being operated (hereinafter collectively referred to as a "Material Event"),
Purchaser may:
<PAGE>
          6.2.1.  terminate this Agreement by written notice to Seller, in
which event the Earnest Money deposited by Purchaser, together with interest
thereon, shall be returned to Purchaser and all rights and obligations of the
parties hereunder with respect to the closing of this transaction will cease;
or

          6.2.2.  proceed with the Closing, in which event Seller shall assign
to Purchaser all of Seller's right, title and interest in and to any award made
in connection with such condemnation or eminent domain proceedings.

     6.3. Purchaser shall then notify Seller, within ten (10) business days
after Purchaser's receipt of Seller's notice or prior to expiration of the Due
Diligence Period, whichever is later, whether Purchaser elects to exercise its
rights under Paragraph 6.2.1 or Paragraph 6.2.2.  Closing shall be delayed, if
necessary, until Purchaser makes such election.  If Purchaser fails to make an
election within such ten (10) business day period, Purchaser shall be deemed to
have elected to exercise its rights under Paragraph 6.2.2.  If between the date
of this Agreement and the Closing Date, any condemnation or eminent domain
proceedings are initiated which do not constitute a Material Event, Purchaser
shall be required to proceed with the Closing, in which event Seller shall
assign to Purchaser all of Seller's right, title and interest in and to any
award made in connection with such condemnation or eminent domain proceedings.

7.   INSPECTION AND AS-IS CONDITION.

     7.1.  During the period commencing on May 5, 1997 and ending at 5:00 p.m.

contractors and surveyors retained by Purchaser may enter upon the Property, at
any reasonable time and upon reasonable prior notice to Seller, to inspect the
Property, including a review of leases located at the Property, and to conduct
and prepare such studies, tests and surveys as Purchaser may deem reasonably
necessary and appropriate.  In connection with Purchaser's review of the

copies of leases affecting the Property, the most recent tax and insurance

under this Paragraph 7.1 by Purchaser shall be at Purchaser's sole cost and
expense and Purchaser shall restore the Property to the condition existing
prior to the performance of such tests or investigations by or on behalf of
Purchaser.  Purchaser shall defend, indemnify and hold Seller and any
affiliate, parent of Seller, and all shareholders, employees, officers and
directors of Seller or Seller's affiliate or parent (hereinafter collectively
referred to as "Affiliate of Seller") harmless from any and all liability, cost
and expense (including without limitation, reasonable attorney's fees, court
costs and costs of appeal) suffered or incurred by Seller or Affiliates of
Seller for injury to persons or property caused by Purchaser's investigations
and inspection of the Property.  Purchaser shall undertake its obligation to
defend set forth in the preceding sentence using attorneys selected by
Purchaser who are reasonably acceptable to Seller.
<PAGE>
     Prior to commencing any such tests, studies and investigations, Purchaser
shall furnish to Seller a certificate of insurance evidencing comprehensive
general public liability insurance insuring the person, firm or entity
performing such tests, studies and investigations and listing Seller and
Purchaser as additional insureds thereunder.

investigations performed or information received pursuant to this Paragraph
7.1, or if Purchaser, in its sole discretion, elects not to purchase the
Property for any reason whatsoever, Purchaser shall have the right to terminate
this Agreement by giving written notice of such termination to Seller at any
time prior to the expiration of the Inspection Period.  If written notice is
not received by Seller pursuant to this Paragraph 7.1 prior to the expiration
of the Inspection Period, then the right of Purchaser to terminate this
Agreement pursuant to this Paragraph 7.1 shall be waived.  If Purchaser
terminates this Agreement by written notice to Seller prior to the expiration
of the Inspection Period: (i) Purchaser shall promptly deliver to Seller copies
of all studies, reports and other investigations obtained by Purchaser in
connection with its due diligence during the Inspection Period; and (ii) the
Earnest Money deposited by Purchaser shall be immediately paid to Purchaser,
together with any interest earned thereon, and neither Purchaser nor Seller
shall have any right, obligation or liability under this Agreement, except for
Purchaser's obligation to indemnify Seller and restore the Property, as more
fully set forth in this Paragraph 7.1.  Notwithstanding anything contained
herein to the contrary, the terms of this Paragraph 7.1, shall survive the
Closing and the delivery of the Deed and  termination of this Agreement.

     7.2.  Seller makes no representations or warranties relating to the
condition of the Property or the Personal Property.  Purchaser acknowledges and

12.  PRORATIONS.

     12.1.     The items described in this Paragraph shall be prorated between
the parties on a per diem basis (on the basis of actual calendar days in the
relevant calendar year) so that credits and charges preceding or on 11:59 P.M.
on day proceeding the Closing Date shall be allocated to Seller and credits and
charges for the period after 11:59 P.M. on the day proceeding the Closing Date
and all days thereafter shall be allocated to Purchaser.  As of December 1,
1997, Seller and Purchaser shall jointly prepare a final proration statement in
accordance with the provisions of this Paragraph 12 and a final adjusting
payment shall then be made, as provided in Paragraph 12.3 hereof.

          12.1.1.  Real estate taxes (on the basis of allowable discounts for
early payments), general and special assessments and the like ("Taxes") for the
tax period of the Closing Date, as such Taxes may be increased or decreased
after the Closing, shall be prorated as of the Closing Date based on the most
recent ascertainable amount as part of the proration of "Maintenance Expenses"
(hereinafter defined) in Paragraph 12.1.3.  

          12.1.2.   Minimum rent (exclusive of delinquent or unpaid rents, but
including prepaid rents) paid under the Leases shall be prorated as of the
Closing Date.  Percentage Rent, if any, shall be prorated in connection with
the final adjustment set forth in Paragraph 12.3 herein.

          12.1.3.   Certain of the Leases provide for reimbursement to lessor
of maintenance and operation charges, Taxes, insurance and other expenses
(herein collectively referred to as "Maintenance Expenses").  Some Leases
provide for a determination of the tenant's share of Maintenance Expenses on an
annual basis but provide that an estimated amount thereof (either in the
aggregate or for specified components thereof) shall be paid by tenant to
lessor monthly during the course of the year with a final adjustment to be made
after the close of the year when such costs and expenses have been finally
determined.  Seller and Purchaser have agreed as follows with respect to
Maintenance Expenses:

         (i)   Except as hereinafter provided, Seller shall be responsible for
the payment of all Maintenance Expenses attributable to periods of time prior
to the Closing Date (without taking into account "stops" for base years in the
Leases) and Seller shall be entitled to receive and retain all reimbursements
thereof collected from tenants on account thereof with respect to the period
through the Closing Date (taking into account "stops" for base years in the
Leases); and Purchaser shall be responsible for the payment of all Maintenance
Expenses attributable to periods of time from and after the Closing Date
(without taking into account "stops" for base years in the Leases) and
Purchaser shall be entitled to receive and retain from the tenants all
reimbursements thereof collected from tenants on account thereof with respect
to the Closing Date and thereafter (taking into account "stops" for base years
in the Leases).  Purchaser shall be entitled to a credit against the Purchase
Price for sums that are due (or accrued) and unpaid as of the Closing Date
under any Service Contracts which have been assigned to Purchaser, and Seller
shall be entitled to a credit to the extent that sums have been paid under any
Service Contracts which have been assigned to Purchaser for services to be
performed or goods to be delivered after the Closing Date.
<PAGE>
        (ii)   As a part of the final proration referred to in Section 12.3
hereof all Maintenance Expenses received from Tenants for the period of time
prior to the Closing Date shall be delivered to Seller.

         12.1.4.    To the extent not covered by Paragraph 12.1.3, utility and
fuel charges, including, without limitation, charges for water, electricity,
gas, gasoline, steam, oil and telephones used in connection with the heating,
cooling, lighting, maintenance and operation of the Property and any personal
property included therein or used in connection therewith shall be prorated as
of the Closing Date.  Seller shall obtain readings of all utility meters no
earlier than 30 days prior to the Closing Date.  As a part of the final
proration referred to in Section 12.3 hereof, prorations under this Section
12.1.4 shall be based upon the actual bills received for the month of Closing.

         12.1.5.    To the extent not covered by Paragraph 12.1.3 annual fees
for the permits and licenses shall be prorated as of the Closing Date.

         12.1.6.    Personal property taxes, if any, for any personal property
transferred to Purchaser shall be prorated as of the Closing Date.

         12.1.7.    Purchaser shall use reasonable, good faith efforts in
collecting from the tenants any under-payments for Maintenance Expenses for
1996 and 1997; provided, however, Purchaser shall have no obligation to enter
into litigation to collect such Maintenance Expenses for 1996 and 1997.

     12.2.     The following amounts, if any (the "Adjustments"), without
duplication, shall be made:

         12.2.1.    All security deposits held by Seller as of the Closing Date
shall be paid to Purchaser at the Closing.

         12.2.2.    All other reasonable expenses normal to the operation and
maintenance of the Property which require payments either in advance or in
arrears for periods which begin prior to the Closing Date or end thereafter
shall be apportioned between Seller and Purchaser as of 11:59 P.M. on the day
preceding the Closing Date.  

         12.2.3.    Purchaser shall receive at Closing a credit equal to the
amount of any unsatisfied obligations for "Tenant Improvement and Leasing
Commissions" of Seller for the Frontier Lease (as hereinafter defined) set
forth in Exhibit O.  Purchaser agrees to assume the payment of the remaining
"Tenant Improvement and Leasing Commissions" as shown on Exhibit O (without a
credit from Seller) and to the extent Seller pays any amounts toward the
remaining "Tenant Improvement and Leasing Commissions" obligation prior to
Closing then Seller shall receive a credit from Purchaser therefor.  Seller
shall receive a credit, if any, as provided in Paragraph 32.  Purchaser shall
assume at Closing all third party construction contracts for the performance of
tenant improvement work and leasing commission agreements in connection with
those leases (i) for which Seller is giving to Purchaser a credit as set forth
on Exhibit O, (ii) for which Purchaser is assuming the obligations without a
credit set forth on Exhibit O and (iii) for which Purchaser is assuming the
obligations pursuant to Paragraph 32 herein.
<PAGE>
     12.3.     In connection with the Prorations and the Adjustments herein and
as provided, there shall be prepared the following statements, schedules and
certificate:

         12.3.1.    Seller shall prepare or cause to be prepared statements in
reasonable detail showing separately each item prorated or adjusted pursuant to
this Agreement and a detailed reconciliation showing separately each item
prorated or adjusted pursuant to this Agreement and a detailed reconciliation
of the Prorations and Adjustments, such statements to be delivered at least
three (3) business days prior to the Closing and adjusted as necessary at the
Closing.  The parties shall mutually agree after review thereof by Purchaser
that said closing statement accurately reflects the method of proration set
forth in this Agreement.  

         12.3.2.    Purchaser, in cooperation with Seller, shall prepare, not
later than December 1, 1997, a final proration statement presenting correctly
the Prorations and Adjustments in accordance with the terms of this Agreement
and a statement of "Post-Closing Receipts" (hereinafter defined).   Upon
issuance of such proration statement the parties shall make a proration payment
as appropriate (including, without limitation, a settlement of Post-Closing
Receipts).  For purposes of preparation of the foregoing statements and at all
reasonable times thereafter, the parties agree to allow the other party and the
other party's accountants and representatives, to examine so much of the books
and records in the possession and control of the other party as relate to such
statements and final reconciliations with tenants on Maintenance Expenses and
other charges at the place or places where they are then regularly maintained.

     12.4.     All sums paid following the Closing Date by any tenant of the
Property who is indebted to Seller for rent, additional rent or any other sum
due under its Lease for any period prior to and including the Closing Date,
after receipt by Purchaser of all then currently due amounts by said tenant and
any reasonable actual out-of-pocket collection costs of Purchaser shall be
deemed a "Post-Closing Receipt" until such time as all such indebtedness to
Seller is paid in full.  Within ten (10) days following each receipt by
Purchaser of a Post-Closing Receipt (other than with respect to a Maintenance
Expense received from a Tenant which will be adjusted as provided in Paragraphs
12.1 and 12.3), Purchaser shall pay such Post-Closing Receipt to Seller.
Purchaser shall use reasonable efforts to collect all amounts which, upon
collection, would constitute Post-Closing Receipts hereunder, but Purchaser
shall not be required to institute legal action on account thereof nor to
engage attorneys or other professionals in such efforts.  If by November 15,
1997 Purchaser has not collected all amounts due Seller and shall not have
commenced litigation to collect such Post-Closing Receipts, Seller, after
notice to Purchaser, may, at Seller's expense, commence litigation to collect
such unpaid arrearage; provided, however, that Seller shall have no right to
commence any proceeding to evict the tenant or recover possession of any
tenant's space or interfere with the tenant's or Purchaser's ability (other
than financial impact resulting from such litigation) to conduct business or
take any action which would limit Purchaser's rights to pursue any remedy
Purchaser may have for a default under any Lease.  Purchaser may, by written
notice to Seller within twenty (20) days of receipt of Seller's notice,
<PAGE>
restrict Seller from collecting such unpaid arrearage, but only if Purchaser
first pays Seller such unpaid arrearage, in exchange for Seller's assignment to
Purchaser of all of Seller's rights and causes of action with respect thereto.
Purchaser shall cooperate fully with Seller, at no expense to Purchaser, in
this regard and shall execute such instruments, if any, as Seller may require
in order for Seller to commence and prosecute any such litigation.

     12.5.     Paragraph 12 of this Agreement shall survive the Closing and the
delivery and recording of the Deed until December 31, 1997.  

13.  RECORDING.  Neither this Agreement nor a memorandum thereof shall be
recorded and the act of recording by Purchaser shall be an act of default
hereunder by Purchaser and subject to the provisions of Paragraph 10 hereof.

14.  ASSIGNMENT.  The Purchaser shall not have the right to assign its interest
in this Agreement without the prior written consent of the Seller.
Notwithstanding the foregoing, Purchaser may assign its interest in this
Agreement without the consent of Seller to any entity affiliated with
Purchaser, or the principals of Purchaser, or to any fund sponsored by
Purchaser or its affiliate, provided that the assignee assumes the obligations
of Purchaser hereunder.  If any assignee of Purchaser under this Agreement
petitions or applies for relief in bankruptcy or Assignee is adjudicated as a
bankrupt or insolvent, or Assignee files any petition, application for relief
or answer-seeking or acquiescing in any reorganization, arrangement,
composition, readjustment, liquidation, dissolution or similar relief for
itself under any present or future federal, state or other statute, law, code
or regulation relating to bankruptcy, insolvency, or other relief for debtors
(collectively, a "Bankruptcy Filing") on or before the Closing Date, said
Bankruptcy Filing shall be a default under this Agreement and Purchaser shall
indemnify Seller for all costs, attorney's fees and expenses of Seller
resulting from Seller's efforts to obtain the Earnest Money as liquidated
damages and to clear title to the Property from any encumbrance resulting from
the Bankruptcy Filing.

15.  BROKER.  The parties hereto represent and warrant that no broker
commission or finder fee is due and payable in connection with this transaction
other than to Insignia Mortgage & Investment Company ("Insignia") (to be paid
by Seller).  Seller's commission to Insignia shall only be payable out of the
proceeds of the sale of the Property in the event the transaction set forth
herein closes.  Purchaser and Seller shall indemnify, defend and hold the other
party hereto harmless from any claim whatsoever (including without limitation,
reasonable attorney's fees, court costs and costs of appeal) from anyone
claiming by or through the indemnifying party any fee, commission or
compensation on account of this Agreement, its negotiation or the sale hereby
contemplated other than to Insignia.  The indemnifying party shall undertake
its obligations set forth in this Paragraph 15 using attorneys selected by the
indemnifying party and reasonably acceptable to the indemnified party.  The
provisions of this Paragraph 15 will survive the Closing and delivery of the
Deed.
<PAGE>
16.  REPRESENTATIONS, WARRANTIES AND COVENANTS.

     16.1.  Any reference herein to Seller's knowledge or notice of any matter
or thing shall only mean such knowledge or notice that has actually been
received by Tom Molina, the asset manager of the Property (the "Seller's
Representative") and any representation or warranty of the Seller is based upon
those matters of which the Seller's Representative has actual knowledge.  Any
knowledge or notice given, had or received by any of Seller's agents, servants
or employees shall not be imputed to Seller, the general partner or limited
partners of Seller, the subpartners of the general partner or limited partners
of Seller or Seller's Representative.  A copy of Paragraph 16.2 shall be
delivered to the on-site management of the Property within two (2) days after
the execution by Seller of this Agreement, with a request to advise Tom Molina
within five (5) business days after receipt by the on-site manager as to the
accuracy and truthfulness of the representations and warranties. If the on-site
manager indicates that any of the representations or warranties were incorrect,
Seller shall notify Purchaser as to the response of the on-site manager by ten
(10) business days after the execution by Seller.  If the on-site manager
responds that any of the representations or warranties were incorrect then the
terms of Paragraph 16.5 herein shall apply.  If Seller fails to so notify
Purchaser, Purchaser shall be entitled to conclude that the on-site manager
reviewed the representations and warranties and that they are correct.

     16.2.  Seller's Representations and Warranties.  Subject to the
limitations set forth in Paragraph 16.1, Seller hereby represents and warrants
to Purchaser, which representations, warranties and covenants are made to
Seller's knowledge and which shall be deemed repeated and made as of the
Closing Date and survive the Closing for a period of the earlier of (i) six (6)
months after the Closing Date and (ii) December 31, 1997 (i.e., the claiming
party shall have no right to make any claims against the other party for a
breach of a representation or warranty after the earlier of the preceding
dates), as follows:

         (a)   Seller is duly organized and legally existing and in good
standing as a limited partnership under the laws of Illinois.  Seller is
registered as a foreign limited partnership under the laws of Michigan.  The
execution and delivery of, and performance under, this Agreement are within
Seller's powers and have been duly authorized by all requisite partnership
action.  The person executing this Agreement on behalf of Seller has the
authority to do so.  This Agreement constitutes the legal, valid and binding
obligation of Seller enforceable in accordance with its terms, subject to
equitable principles and laws applicable generally to creditor's rights.
Performance of this Agreement will not result in any breach of, or constitute
any default under, or result in the imposition of a lien or encumbrance on the
Property under, any agreement or other instrument to which Seller is a party or
by which Seller or the Property might be bound.  To Seller's knowledge, there
is no other person or entity who has an ownership interest in the Property or
whose consent is required in connection with Seller's performance of its
obligations hereunder which consent has not been obtained.
<PAGE>
         (b)   There is no pending or threatened litigation or administrative
proceedings which would adversely affect the ability of Seller to perform any
of its obligations hereunder.  No consent or approval of any person or entity
or of any governmental authority is required with respect to the execution and
delivery of this Agreement by Seller or the consummation by Seller of the
transactions contemplated hereby or the performance by Seller of its
obligations hereunder.

         (c)   There are no parties in possession of any of the Property other
than tenants pursuant to the Rent Roll listed on Exhibit M hereto.

         (d)   There is no pending or threatened condemnation or similar
proceeding affecting any of the Property or interest therein.

         (e)   There is no proceeding or threatened action or proceeding which
could result in a modification or termination of the present zoning of the
Property.

         (f)   There is no action, suit or proceeding pending or threatened
against or affecting Seller in any court, before any arbitrator or before or by
any Governmental Authority which (a) could adversely affect title to the
Property or any part thereof or the use of the Property by Purchaser or
otherwise affect the Property in any way, (b) in any manner raises any question
affecting the validity or enforceability of this Agreement or any other
agreement or instrument to which Seller is a party or by which it is bound and
that is or is to be used in connection with, or is contemplated by, this
Agreement, or (c) could materially and adversely affect the business, financial
position or results of operations of Seller or the Property.

         (g)   Except as shown on the Rent Roll attached hereto as Exhibit M or
the Tenant Leases delivered by Seller to Purchaser in connection with
Purchaser's review pursuant to Section 7.1, (i) neither Seller nor the tenant
is in default any of the Tenant Leases; (ii) each tenant has accepted the
premises covered by its Tenant Lease and is in possession of such premises in
accordance with its Lease, and (iii) no tenant or any other person or entity
has any interest in the Property, or right or option to acquire any interest in
the Property, other than the leasehold possessory interest set forth in the
respective tenants' Tenant Leases.  No tenant has given written notice to
Seller of its intention to institute litigation with respect to any Tenant
Lease or terminating its tenancy.

         (h)   No brokerage commissions or compensation of any kind shall be
due in connection with the Tenant Leases or any extensions or renewals thereof

management, service, supply, maintenance and other contracts and agreements
(other than Tenant Leases) in effect which affect the Property or are otherwise
related to the construction, ownership, operation, occupancy or maintenance
thereof (collectively, the "Service Contracts").  

         (j)   Exhibit B attached hereto is a list of all the personal property
owned by Seller and used or useful in connection with the maintenance, repair
or operation of the Property.
<PAGE>
         (k)   All insurance policies maintained by or on behalf of Seller
pertaining to any of the Property or the operation thereof are valid and in
full force and effect and Seller has complied with all requirements or
recommendations of the insurance carriers of such policies.  Seller has
received no notice from any insurance company or rating organization to the
effect that the physical condition of the Property would prevent obtaining new
insurance policies at present rates.

         (l)   There are no property interests, buildings, structures or other
improvements or personal property located on the Property that are owned by
Seller which are necessary for the operation of the Property that are not being
conveyed pursuant to this Agreement.

     16.3.  Purchaser's Representations.  As of the date of this Agreement,
Purchaser represents to Seller that:

         (a)   Purchaser is duly organized and legally existing as a limited
partnership under the laws of Delaware.  The execution and delivery of, and
performance under, this Agreement are within Purchaser's powers and have been
duly authorized by all requisite corporate action.  The person executing this
Agreement on behalf of Purchaser has the authority to do so.  This Agreement
constitutes the legal, valid and binding obligation of Purchaser enforceable in
accordance with its terms.  Performance of this Agreement will not result in
any breach of, or constitute any default under, any material agreement or other
instrument to which Purchaser is a party or by which Purchaser or the Property
might be bound.

         (b)   There is no pending or, to Purchaser's knowledge, threatened
litigation or administrative proceedings which would adversely affect the
ability of Purchaser to perform any of its obligations hereunder.  No consent
or approval of any person or entity or of any governmental authority is
required with respect to the execution and delivery of this Agreement by
Purchaser or the consummation by Purchaser of the transactions contemplated
hereby or the performance by Purchaser of its obligations hereunder.

     16.4.     Seller's Covenants.  Seller hereby covenants and agrees with
Purchaser that, after the date of this Agreement, and prior to Closing (or any
earlier termination of this Agreement pursuant to its terms):

         (a)   Seller will cause the Property to be maintained and operated in
a good and workmanlike manner and in accordance with all applicable laws,
Seller will not use or occupy, or allow the use or occupancy of, the Property
in any manner which violates any applicable laws.  Seller will continue to
maintain and operate the Property as a first class office building in
accordance with the practices of a prudent real estate operator and shall
continue to offer services and amenities in accordance with past practices,
subject to the restrictions contained in this Agreement.

         (b)   Seller will not remove or cause or permit to be removed any
equipment, fixtures or personal property forming part of the Property unless
the same is replaced, prior to Closing, with similar items of at least equal
suitability, quality and value, free and clear of any liens or security
interests.
<PAGE>
         (c)   Seller will pay all premiums on, and will not cancel or
voluntarily allow to expire, any of Seller's insurance policies with respect to
any of the Property unless such policy is replaced, without any lapse of
coverage, by another policy or policies providing coverage at least as
extensive as the policy or policies being replaced.

         (d)   Seller will not seek any zoning changes without Purchaser's
prior written consent.

         (e)   Seller will maintain its books of account and records in the
usual, regular and ordinary manner, in accordance with sound accounting
principles applied on a basis consistent with the basis used in keeping its
books in prior years.
         (f)   Seller will not, without the prior written consent of Purchaser,
enter into any new employment, management, service, maintenance or union
agreements relating to the Property or modify, renew or extend any contracts,
unless such new agreements and such contracts, as renewed or extended, will be
cancelable by Purchaser on not more than thirty (30) days prior notice without
any costs for such cancellation.

     16.5.     If at any time after the execution of this Agreement, either
Purchaser or Seller become aware of information (a "Change") which makes a
representation and warranty contained in this Agreement untrue in any material
respect without regard to limitation based upon personal knowledge, said party
shall promptly disclose said information to the other party hereto.  Provided
the party making the representation or warranty did not take any deliberate
actions to cause the representation or warranty in question to become untrue in
any material respect and did not intentionally make a material false
representation or warranty, said party shall not be in default under this
Agreement and the sole remedy of the other party shall be to terminate this
Agreement, in which case Purchaser will receive a refund of the Earnest Money
with any accrued interest thereon and neither party will have any further
liability under this Agreement except to the extent it specifically survives
the termination hereof.  Purchaser, provided that it notifies Seller within ten
(10) days after receiving notice from Seller of a Change, may elect to close
subject to such Change and then both parties hereto will be deemed to have
waived their right to terminate this Agreement with respect to such Change.
Notwithstanding anything contained herein to the contrary, if the status of any
of the tenancies changes as a result of the actions of a tenant from the date
of the rent roll attached hereto and the date of the rent roll delivered at
Closing, provided the change in status is not caused by a breach of Seller's
covenants contained in Paragraph 16.4, then Purchaser shall not have the right
to terminate this Agreement or make any claim for a breach of a representation
or warranty hereunder involving the rent roll or tenancies thereunder.
Purchaser and Seller are prohibited from making any claims against the other
party hereto after the Closing with respect to any breaches of the other
party's representations and warranties contained in this Agreement that the
claiming party has actual knowledge of prior to the Closing.
<PAGE>
17.  LIMITATION OF LIABILITY.  

     17.1. Neither Seller, nor any Affiliate of Seller, nor any of their
respective beneficiaries, shareholders, partners, officers, directors, agents
or employees, heirs, successors or assigns shall have any personal liability of
any kind or nature for or by reason of any matter or thing whatsoever under, in
connection with, arising out of or in any way related to this Agreement and the
transactions contemplated herein, and Purchaser hereby waives for itself and
anyone who may claim by, through or under Purchaser any and all rights to sue
or recover on account of any such alleged personal liability.

     17.2.     Notwithstanding anything contained herein to the contrary,
Purchaser hereby agrees that the maximum aggregate liability of Seller for

punitive damages), in connection with, arising out of or in any way related to
a breach by Seller under this Agreement or any document or conveyance agreement
in connection with the transaction set forth herein after the Closing shall be
$400,000.00.  

     17.3.     Except for Purchaser's obligation to deposit the Earnest Money
and indemnify Seller pursuant to the terms of this Agreement, neither
Purchaser, nor any Affiliate of Purchaser, nor any of their respective
beneficiaries, shareholders, partners, officers, directors, agents or
employees, heirs, successors or assigns shall have any personal liability of
any kind or nature for or by reason of any matter or thing whatsoever under, in
connection with, arising out of or in any way related to this Agreement and the
transactions contemplated herein, and Seller hereby waives for itself and
anyone who may claim by, through or under Seller any and all rights to sue or

32.  NEW LEASES.  On or before five (5) business days prior to the expiration
of the Inspection Period, Seller may execute any new lease or modify or renew
any existing lease affecting the Property without Purchaser's consent, provided
the terms of such new lease or modification or extension to existing lease are
commercially reasonable.  Seller shall deliver a copy of any such new lease or
existing lease modification or renewal (together with an estimation of the "New
Lease Costs" (as hereinafter defined)), as applicable, to Purchaser within
three (3) business days of execution by the new tenant or existing tenant, as
applicable, but in any event on or before four (4) business days prior to the
expiration of the Inspection Period.  In the event Purchaser disapproves of
such new lease or existing lease modification or renewal, within three (3)
business days of the receipt of such new lease or existing lease modification
or renewal, Purchaser shall either (i) terminate this Agreement in accordance
with Paragraph 7 hereof or (ii) direct Seller to not execute such new lease or
existing lease modification or renewal and waive Purchaser's right to terminate
this Agreement in accordance with Paragraph 7.  In the event that Purchaser
does not terminate this Agreement as aforesaid, Purchaser shall be responsible
for the costs of all tenant improvements, leasing costs and commissions and
reasonable attorney's fees associated with the negotiation and execution of any
such new lease or existing lease modification or renewal ("New Lease Costs").
Seller shall receive a credit at Closing for any New Lease Cost incurred by
Seller prior to Closing.
<PAGE>
     After the date five (5) business days prior to the expiration of the
Inspection Period, Seller shall not execute any new lease or existing lease
modification or renewal affecting the Property without Purchaser's prior
written consent, which shall not be unreasonably withheld.  Purchaser's consent
shall be deemed given if Purchaser has not responded to the contrary within
five (5) business days after Seller's written request and Purchaser's receipt
of such new lease or existing lease modification or renewal (together with an
estimation of the New Lease Costs).  If approved by Purchaser, a complete copy
of any such new lease or existing lease modification or renewal shall be
delivered to Purchaser within ten (10) days of the full execution thereof.  All
New Lease Costs shall be paid by Purchaser and Seller shall receive a credit at
Closing for any New Lease Costs incurred by Seller prior to Closing.

     Purchaser acknowledges that there currently exists the unsatisfied tenant
improvement obligations and leasing commissions set forth on Exhibit O attached
hereto.  With respect to all tenant improvements and leasing commission
obligations set forth on Exhibit O, Purchaser shall assume the obligations for
the payment thereof and credit Seller at Closing for any amounts paid toward
the aforesaid tenant improvements or leasing commission obligations set forth
on Exhibit O, except for the payment of the tenant improvements and leasing
commissions for the Frontier Lease (defined below).  In the event the current
leases for the Property include unsatisfied tenant improvement obligations or
leasing commissions not listed on Exhibit O, Seller shall be solely responsible
for such tenant improvement obligations and leasing commissions.

the Inspection Period for a term until March 31, 2004 and with minimum
effective base rent as follows:  $17.75 per square foot the first lease year,
increased by $.25 per square foot each subsequent lease year.  In the event
that (a) Seller and Frontier do not execute the Frontier Lease prior to the end
of the Inspection Period and (b) Purchaser does not terminate this Agreement
pursuant to Paragraph 7.1, Purchaser will not be entitled to terminate this
Agreement by reason of the failure of Seller and Frontier to execute the
Frontier Lease.  Seller shall not be liable under the Agreement if Seller and
Frontier do not execute and deliver the Frontier Lease.  Seller shall pay the
New Lease Costs (including free rent credits) for the Frontier Lease, for which
Seller shall not be entitled to a credit at Closing.  To the extent the New
Lease Costs for the Frontier Lease have not been paid as of the Closing Date,
Seller will provide Purchaser with a credit at the Closing for such unpaid New
Lease Costs of the Frontier Lease.

33.  TENANT CERTIFICATE CONDITION TO CLOSING.  

     33.1.     The following terms have been defined as follows for convenience
of reference:

          (i)  "Tenant Certificate" means a certificate, commonly known as an
estoppel certificate, signed by a tenant with respect to its Lease, either in
the form set forth on Exhibit L hereto or on such other form as is
substantially consistent with the requirements of the tenant's lease for such
certificates;
<PAGE>
          (ii) "Seller Tenant Certificate" means a Tenant Certificate signed by
the Seller with respect to a particular Lease for which the Tenant in question
has failed to execute and deliver a Tenant Certificate, in which case the
Seller Tenant Certificate shall be in the form of Exhibit L; provided further
that a Seller Tenant Certificate shall in all cases be limited to Seller's
knowledge as defined in Paragraph 16.1 hereof;

          (iii)     "Qualification" means any assertion in a Tenant Certificate
(whether in the form of Exhibit L or otherwise) of (i) a claim, counterclaim,
offset or defense against the landlord, (ii) a default on the part of the
landlord, (iii) unpaid credits, allowances or other sums due from the landlord
prior to the date of the estoppel (other than disclosed in Paragraph 12.1
herein or pursuant to a new lease pursuant to Paragraph 32 herein), (iv) an
unfulfilled construction or other obligation on the part of the landlord prior
to the date of estoppel (other than disclosed in Paragraph 12.1 herein or
pursuant to a new lease pursuant to Paragraph 32 herein), or (v) information
which is contrary (in an adverse respect to the landlord) (x) to the
information contained in the rent roll attached hereto as Exhibit M, or (y) the
information pertaining to tenant allowances and concessions and leasing
commissions contained in Paragraph 12.1;

          (iii)     "Unacceptable Qualification" means any Qualification other
than the following:

               (a)  a Qualification which is expressly disclosed on the rent
roll attached hereto as Exhibit M or a Qualification relating to non-payment of
April, 1997 or May, 1997 rent, provided the same is not as a result of a
default by Landlord;

               (b)  a Qualification which is specifically and clearly disclosed
in the Lease of the Tenant in question which was delivered or made available to
Purchaser prior to the expiration of the Inspection Period;

               (c)  a Qualification expressly disclosed in this Agreement or
the Exhibits hereto; or

               (d)  a disclosure by a Tenant of physical defects to the portion
of the Property generally known as the common area.

     33.2.     If a Qualification is not an Unacceptable Qualification, it
shall not affect Purchaser's obligations to close hereunder or give rise to any
liability from Seller to Purchaser.

     33.3.     Seller shall promptly request a Tenant Certificate in the form
of Exhibit L from all tenants, and shall vigorously, in good faith, pursue the
collection of the same.  Seller shall deliver to Purchaser, upon Seller's
receipt thereof, all Tenant Certificates signed by tenants (whether in the form
of Exhibit L or otherwise).  Purchaser shall have the right to assist Seller in
obtaining the Tenant Certificates.
<PAGE>
     33.4.     It shall be a condition to Purchaser's obligations hereunder
(the "Estoppel Condition") that Seller deliver to Purchaser, at or prior to
5:00 p.m. Chicago time on June 13, 1997, either a Tenant Certificate or Seller
Certificate from (i) all tenants occupying 5000 square feet or more of the
gross leasable area of the Property and (ii) such additional tenants with
leases occupying an aggregate of eighty percent (80%) of the occupied leasable
area of the Property.  Seller shall be required to deliver to Purchaser all
Tenant Certificates received by Seller from the tenants at the Property.
Notwithstanding the foregoing to the contrary, Seller shall not have satisfied
the Estoppel Condition if any of the Tenant Certificates received by Seller,
disclose Unacceptable Qualifications other than Unacceptable Qualifications
with an "Estoppel Qualification Sum" (hereinafter defined) of less than $50,000
in the aggregate.  The "Estoppel Qualification Sum" shall mean the following:

          (i)  if the claim asserted arises out of a defect which can be cured,
with the expenditure of money on a one time basis, such as a physical defect,
then such sum shall be calculated by a reasonable estimate of the cost to
repair or remediate said defect;

          (ii) if the claim asserted affects a continuing obligation of a
tenant under the lease, such as the payment of rent, then the claim shall be
calculated by (a) determining the amount of the claim on a per annum basis, (b)
multiplying said amount by the number of years or partial years said claim
would affect the monetary obligations under the lease and (c) discounting said
product on a present value basis using a discount rate of 10% per annum; and

          (iii)     if the claim asserted is of a nature with which a monetary
value is not customarily associated, the parties agree to negotiate in good
faith to agree upon an appropriate monetary value for such claim. 

     If the Unacceptable Qualifications have an Estoppel Qualification Sum of
less than $50,000 in the aggregate, then Seller shall either (x) grant
Purchaser a credit at Closing for an amount equal to the Estoppel Qualification
Sum, or (y) cure all conditions giving rise to an Unacceptable Qualification on
or before the Closing.  The determination to perform the covenant contained in
subparagraphs (x) or (y) in the preceding sentence shall be made by Seller.
Provided Seller performs its covenant in this Paragraph 33.4, the disclosure of
Unacceptable Qualifications having an Estoppel Qualification Sum of less than
$50,000 in the aggregate shall not affect Purchaser's obligations to close
hereunder or give rise to any additional liability from Seller to Purchaser.

     33.5.     If Seller has not satisfied the Estoppel Condition on or before
5:00 p.m. Chicago time on June 13, 1997, then Purchaser shall have the right to
terminate this Agreement by delivering written notice to Seller on or before
5:00 p.m. Chicago time on June 16, 1997.  If Purchaser exercises its rights to
terminate in accordance with the terms of this Paragraph 33.5, this Agreement
shall be null and void without further action of the parties and all Earnest
Money theretofore deposited by Purchaser together with any interest accrued
thereon, shall be returned to Purchaser, and neither party shall have any
further liability to the other, except for Purchaser's obligation to indemnify
Seller and restore the Property, as more fully set forth in Paragraph 7 hereof.
<PAGE>
If Purchaser does not terminate this Agreement pursuant to the first sentence
of this Paragraph 33.5, the parties shall proceed to Closing and (i) Purchaser
shall receive a credit at Closing equal to the amount of the Estoppel
Qualification Sum of the Unacceptable Qualifications contained in the Tenant
Certificates, up to an aggregate amount of $50,000 or (ii) Seller shall cure
all conditions giving rise to an Unacceptable Qualification Sum up to an
aggregate amount of $50,000.  The determination to perform the covenant
contained in subparagraphs (i) or (ii) in the preceding sentence shall be made
by Seller.

     33.6.     Notwithstanding anything contained herein to the contrary, if
Seller does not satisfy the Estoppel Condition because the estoppel
qualification sum exceeds $50,000 and Purchaser has terminated the Agreement
pursuant to Paragraph 33.5, Seller shall have the right to vitiate Purchaser's
termination by written notice on or before 5:00 p.m. Chicago time on June 18,
1997 in which case the parties shall proceed to Closing and Seller shall either
(i) grant Purchaser at Closing for an amount to the Estoppel Qualification Sum
or (ii) cure all conditions giving rise to an Unacceptable Qualification on or
before the Closing.  The determination to perform the covenant contained in
subparagraphs (i) or (ii) in the preceding sentence shall be made by Seller.
<PAGE>
     IN WITNESS WHEREOF, the parties hereto have put their hand and seal as of
the date first set forth above.
