         favor of a third  party  which would  prevent  SELLER from  selling the
         PROPERTY to  PURCHASER  or which  would bind  PURCHASER  following  the
         Closing. At Closing, SELLER shall deliver a release of the Option.

         B.       NO  ADDITIONAL   REPRESENTATIONS   OR  WARRANTIES  OF  SELLER.
PURCHASER  ACKNOWLEDGES AND AGREES THAT,  EXCEPT AS EXPRESSLY  SPECIFIED IN THIS
AGREEMENT,  ITS EXHIBITS, AND OTHER CLOSING DOCUMENTS EXECUTED BY SELLER. SELLER
HAS NOT MADE, AND SELLER HEREBY  SPECIFICALLY  DISCLAIMS,  ANY REPRESENTATION OR
WARRANTY  OF ANY KIND,  ORAL OR  WRITTEN,  EXPRESS  OR  IMPLIED,  OR  ARISING BY
OPERATION OF LAW,  WITH RESPECT TO THE PROPERTY  INCLUDING,  BUT NOT LIMITED TO,
ANY WARRANTIES OR REPRESENTATIONS AS TO HABITABILITY,  MERCHANTABILITY,  FITNESS
FOR  A  PARTICULAR  PURPOSE,  TITLE,  ZONING,  TAX  CONSEQUENCES,   PHYSICAL  OR
ENVIRONMENTAL  CONDITION,  UTILITIES,  VALUATION,  GOVERNMENTAL  APPROVALS,  THE
COMPLIANCE OF THE PROPERTY WITH GOVERNMENTAL  LAWS, OR ANY OTHER MATTER OR THING
REGARDING THE PROPERTY. PURCHASER AGREES TO ACCEPT THE PROPERTY AND ACKNOWLEDGES
THAT THE SALE OF THE  PROPERTY AS PROVIDED FOR HEREIN IS MADE BY SELLER ON AN AS
IS, WHERE IS, AND WITH ALL FAULTS BASIS.  PURCHASER IS AN EXPERIENCED  PURCHASER
OF  PROPERTIES  SUCH AS THE  PROPERTY  AND  PURCHASER  HAS  MADE  OR  WILL  MAKE
PURCHASER'S OWN  INDEPENDENT  INVESTIGATION  OF THE PROPERTY.  THE PROVISIONS OF
THIS PARAGRAPH SHALL SURVIVE THE CLOSING HEREUNDER.

         C.       PURCHASER'S  Representations and Warranties.  To induce SELLER
to enter into this  Agreement and to sell the PROPERTY,  PURCHASER  hereby makes
the following  representations  and warranties as of the Effective Date each and
all of which shall be true,  correct and complete in all material respects as of
the Closing Date (which representations and warranties shall survive Closing for
a period of 2 years).

                  1) Authority.  PURCHASER  (i) is a duly  organized and validly
         existing  limited  liability  company  under  the laws of the  State of
         Michigan  and (ii) has the  power  and  authority  (A) to  execute  and
         deliver this  Agreement and all other  documents and  instruments to be
         executed  and  delivered  by it  hereunder,  and  (B)  to  perform  its
         obligations  hereunder and under such other documents and  instruments.
         All necessary  actions have been taken by the members and/or manager of
         PURCHASER to confer upon the persons  executing  this Agreement and all
         documents and instruments that are  contemplated  hereby on PURCHASER'S
         behalf the power and authority to do so.

                  2)  Compliance  with  Laws.  Neither  the  execution  of  this
         Agreement nor the consummation of the transaction  contemplated  hereby
         will  constitute or result in a violation or breach by PURCHASER of any
         judgment,  order, writ,  injunction or decree issued against or imposed
         upon it, or will result in a violation of any applicable statute,  law,
         ordinance, rule or regulation.  There is no action, suit, proceeding or
         investigation



                                       8


         pending  or,  to  PURCHASER'S  knowledge,  overtly  threatened  against
         PURCHASER  that would  prevent  the  transaction  contemplated  by this
         Agreement  or that  questions  the  validity or  enforceability  of the
         transaction contemplated by this Agreement or any action taken pursuant
         hereto.   No  approval,   consent,   order  or  authorization   of,  or
         designation, registration or filing (other than for recording purposes)
         with any  governmental  authority  is required in  connection  with the
         execution and delivery of this  Agreement,  the compliance by PURCHASER
         with the  provisions  hereof and the  consummation  of the  transaction
         contemplated hereby.

                  3) Conflict With Other Instruments and Agreements. Neither the
         execution  of this  Agreement  by  PURCHASER  nor the  consummation  by
         PURCHASER  of the  transaction  contemplated  hereby will (i)  conflict
         with,  or  result  in  a  breach  of,  any  provision  of   PURCHASER'S
         organizational  documents, or (ii) conflict with, result in a breach of
         any term of, or in the  termination  of, or  accelerate  or permit  the
         acceleration  of performance  required by the terms of, or give rise to
         any rights of  termination  or  cancellation  under,  any instrument or
         agreement to which PURCHASER is a party, or by which it may be bound.

         13.      PURCHASER  DEPOSIT.  Within three (3) business  days after the
Effective  Date,  PURCHASER  shall deliver to the Title Insurer a deposit in the
sum of $100,000 (the "Deposit")showing PURCHASER'S good faith which will be held
in escrow by the Title Insurer.  If PURCHASER  terminates this Agreement  within
the Study Period or the Study Period  Extension,  as provided herein,  or if the
terms of purchase are subject to any  contingencies as specified,  which are not
satisfied  (or waived) by the date of Closing or such  earlier date as set forth
in this Agreement,  the deposit shall be refunded to PURCHASER.  In the event of
default by  PURCHASER,  the  deposit  shall be  forfeited  and paid to SELLER as
liquidated damages for such default as SELLER'S sole and exclusive remedy.

         14.      COVENANTS.

         A.       Condition of the PROPERTY.  SELLER, at SELLER'S expense, shall
maintain the PROPERTY in the same  condition as on the  Effective  Date,  normal
wear and tear excepted.

         B.       Operation  Until  Closing.  Between the Effective Date and the
Closing Date, SELLER shall:

                  1) Not  transfer,  convey,  hypothecate,  knowingly  create  a
         security  interest in or lien upon, or otherwise  dispose of any of the
         PROPERTY;

                  2) Comply with all  applicable  federal,  state and  municipal
         laws, ordinances, and regulations relating to the PROPERTY;

                  3) Promptly give written notice to PURCHASER of the occurrence
         of any event materially  affecting the substance of the representations
         and warranties made hereunder; and



                                       9


         C.       The Construction Contract.  Between the Effective Date and the
Closing, SELLER shall not modify the Construction Contract in any manner.

         15.      ENVIRONMENTAL.  Within the Study Period,  SELLER shall provide
PURCHASER  with a written  update of the  existing  Phase I  Environmental  Site
Assessment  (certified to PURCHASER) from an environmental company acceptable to
PURCHASER which shall conclude that the  environmental  company has no reason to
believe that the PROPERTY is a facility as defined by MNREPA,  the cost of which
shall  be  shared  equally  by  SELLER  and  PURCHASER.  PURCHASER  agrees  that
Engineering & Environmental  Service Group, Inc. is an acceptable  environmental
consulting company.

         16.      STUDY PERIOD.  SELLER and PURCHASER hereby acknowledge that as
of the Effective Date,  PURCHASER has not yet had an opportunity to complete its
required due  diligence and fully review and evaluate  this  transaction.  For a
period of  twenty  one (21)  days  following  the  Effective  Date  (the  "Study
Period"),  PURCHASER  shall  have the right to enter  upon the  PROPERTY  and to
perform, at its expense, boring tests, engineering, topographic,  environmental,
survey and  marketing  tests or any other  studies,  tests and due  diligence as
PURCHASER elects,  including,  without limitation,  the following: (i) review of
title work, Permitted Exceptions,  the PROPERTY, legal description,  ingress and
egress,  all recorded  easements  and  restrictions  and the ALTA  survey;  (ii)
inspection of the PROPERTY,  (iii)  confirming  that all necessary site plan and
other land use approvals have been issued by all  governmental  entities  having
jurisdiction over the PROPERTY and that the PROPERTY is appropriately  zoned for
PURCHASER'S  intended use, (iv) the Phase I Environmental  Site Assessment;  and
(v) any wetlands permits  applicable to the PROPERTY.  Notwithstanding  anything
contained in this Section 16 to the contrary, PURCHASER shall have at least five
(5) business days to review the title commitment, the ALTA survey, and the Phase
I  Environmental  Site  Assessment,  and the parties agree that the Study Period
shall be  extended,  as  necessary  (the  "Study  Period  Extension")  to permit
PURCHASER the full 5 business days to review and evaluate such  information that
is required to be provided during the Study Period.

          Any test, examinations or inspections of the PROPERTY by PURCHASER and
all costs and expenses in connection with PURCHASER'S inspection of the PROPERTY
shall be at the sole cost of  PURCHASER  (except as  otherwise  provided in this
Agreement).  Upon  completion  of any  such  inspection,  examination,  or test,
PURCHASER shall restore any damage to the PROPERTY caused by Buyer's inspection.
PURCHASER  hereby  indemnifies  and holds SELLER harmless from all loss, cost or
expense,  including,  but not  limited  to,  attorneys'  fees  and  court  costs
resulting from PURCHASER'S inspections in connection with the PROPERTY. If prior
to the expiration of the Study Period or the Study Period  Extension,  PURCHASER
determines,  in its  sole  and  absolute  discretion,  and for any or no  reason
whatsoever,  that  PURCHASER  does not desire to  purchase  the  PROPERTY,  then
PURCHASER  shall have the right to give  written  notice to SELLER  electing  to
terminate this  Agreement,  provided such notice is delivered to SELLER prior to
5:00 p.m. EST of the last day of the Study Period or the Study Period Extension,
whichever is later. In the event such notice of termination is delivered,  then,
the Title Insurer will deliver to PURCHASER  the Deposit,  and the parties shall
be released from all further obligations each to the other under this Agreement.
In the event that the PURCHASER  does not terminate  this Agreement as set forth
in this Section 16, then the  contingency  set forth in this Section 16 shall be
deemed satisfied or waived by PURCHASER.



                                       10


         17.      ADDITIONAL CONDITIONS PRECEDENT.

         A.       Conditions for the Protection of PURCHASER. Provided PURCHASER
does not terminate this Agreement in accordance with Section 16 hereof, it shall
be an additional  condition precedent to PURCHASER'S  obligation to purchase the
PROPERTY  and to perform  its other  obligations  hereunder  that the  following
conditions shall have been satisfied at or before Closing.

                  1) Prior to Closing,  the condition of the improvements  shall
         not have changed in any material respect from the condition  thereof as
         of the Effective Date, normal wear and tear excepted.

                  2) SELLER  shall have  delivered to the Title  Insurer,  on or
         before the Closing Date, all of the documents required under Section 11
         hereof.

                  3) All  of the  covenants,  representations,  warranties,  and
         agreements of SELLER set forth in this Agreement shall be true, correct
         and complete in all material respects as of the Closing Date.

                  4) The  Contractor  shall  have  executed  an  Assignment  and
         Assumption  Agreement in form and content  satisfactory to PURCHASER in
         its sole and absolute  discretion,  substantially in the form attached,
         including  estoppel  certificate,  verification  of  the  balance  due,
         absence of any defaults thereunder, and its willingness to complete the
         Construction Contract within an acceptable time frame.

                  5) SELLER shall have  obtained a  satisfactory  release of all
         obligations,  penalties,  and  requirements  under the Bonds originally
         utilized by SELLER to finance the PROPERTY.

         B.       PURCHASER'S Right to Terminate.  If any condition above is not
satisfied  as of the  Closing  Date,  PURCHASER  shall  have the  option  to (i)
terminate its  obligation  to purchase the PROPERTY,  in which event the Deposit
shall be  returned  to  PURCHASER,  and  neither  party  shall have any  further
liability  or  obligation  hereunder;  or (ii)  extend the time for Closing by a
period not in excess of thirty (30) days to permit  SELLER to fully  satisfy any
unsatisfied  condition.  If PURCHASER extends the conditions for thirty days and
the conditions are still not satisfied by the end of such period, this Agreement
shall  terminate,  the Deposit  shall be returned to  PURCHASER  and the parties
shall have no further liabilities or obligations under this Agreement.

         18.      TAX FREE EXCHANGE.

         A.       Section 1031 Exchange. PURCHASER'S acquisition of the PROPERTY
may be the  acquisition  of  replacement  PROPERTY in a  qualifying  exchange of
like-kind  PROPERTY or a reverse  exchange  under  Section  1031 of the Internal
Revenue Code, as amended and as further supplemented by Internal Revenue Service
Revenue Procedure 2000-37 (the  "Exchange")),



                                       11


pursuant  to   PURCHASER'S   separate   Exchange   Agreement  with  a  qualified
intermediary  (the  "Intermediary").  SELLER agrees to cooperate  with PURCHASER
(without  liability or cost to SELLER) in the  completion of the Exchange.  Such
cooperation  shall  include (i) the  assignment of this Contract by PURCHASER to
the Intermediary,  and the acknowledgment of such assignment by SELLER, (ii) the
acceptance of the Net Purchase Price from the  Intermediary,  (iii) the transfer
of the  Property  to an  "Exchange  Accommodation  Titleholder",  as  defined in
Revenue Procedure 2000-37, or assignee.  In consideration for the cooperation of
SELLER,  SELLER shall not be liable for any acts or  omissions  arising from its
relationship  with the  Intermediary.  Upon  receipt of title to the PROPERTY by
PURCHASER and payment of the consideration payable to SELLER or for its benefit,
under  this  Agreement,  SELLER  shall  not  have  any  further  obligations  or
responsibilities  under this paragraph and PURCHASER  agrees to fully  indemnify
SELLER from any resulting liability to third parties (including, but not limited
to, the  Intermediary)  which  indemnity  shall be effective  from and after the
Effective  Date,  shall not merge with the  conveyance of the PROPERTY and shall
survive the Closing of this transaction or the termination of this Agreement.

         B.       PURCHASER shall in all events be responsible for all costs and
expenses  related to the  Exchange  and shall fully  indemnify,  defend and hold
SELLER  harmless for, from and against any and all liability,  claims,  damages,
expenses  (including,  without  limitation,  reasonable  attorneys fees), taxes,
fees,  proceedings and causes of action of any kind or nature whatsoever arising
out of, connected with or in any manner related to the transaction  contemplated
by this  Agreement or such  Exchange that would not have been incurred by SELLER
if  the  transaction  did  not  involve  an  Exchange.  The  provisions  of  the
immediately  preceding sentence shall survive Closing or the termination of this
Agreement.  Any Exchange shall be consummated on behalf of PURCHASER through the
use of a  facilitator  or  intermediary,  and SELLER  shall not be  required  to
acquire title to any real PROPERTY in connection therewith.

         C.       Disclaimer.  PURCHASER HEREBY  ACKNOWLEDGES  THAT PURCHASER IS
AND  SHALL BE  SOLELY  RESPONSIBLE  FOR  COMPLIANCE  WITH ALL  LAWS,  RULES  AND
REGULATIONS  RELATED  TO THE  EXCHANGE.  FURTHER,  PURCHASER  ACKNOWLEDGES  THAT
NEITHER SELLER NOR ANY OF ITS AGENTS,  REPRESENTATIVES OR AFFILIATES HAS ADVISED
PURCHASER,  AND NO SUCH  PERSON OR ENTITY HAS ANY  OBLIGATION  OR DUTY TO ADVISE
PURCHASER,  WITH  RESPECT  TO  WHETHER  THE  TRANSACTION  CONTEMPLATED  BY  THIS
AGREEMENT  COMPLIES  WITH THE LAWS,  RULES  AND  REGULATIONS  APPLICABLE  TO THE
EXCHANGE.  FURTHER,  PURCHASER  REPRESENTS,  WARRANTS AND ACKNOWLEDGES TO SELLER
THAT IT HAS RELIED UPON ITS OWN TAX AND LEGAL COUNSEL IN DETERMINING  COMPLIANCE
WITH ALL LAWS, RULES AND REGULATIONS  APPLICABLE TO THE EXCHANGE. THE PROVISIONS
OF THIS SECTION SHALL SURVIVE THE CLOSING OR TERMINATION OF THIS AGREEMENT.

         19.      RISK OF LOSS.  If between the  Effective  Date and the Closing
Date, all or any part of the PROPERTY is damaged by fire or natural  elements or
other causes  beyond  SELLER'S  control  which  cannot be repaired  prior to the
Closing  Date,  or any part of the  PROPERTY  is taken  pursuant to any power of
eminent domain,  SELLER shall  immediately



                                       12


notify PURCHASER of such occurrence,  and PURCHASER may terminate this Agreement
by  written  notice to the  SELLER  within  fifteen  (15) days after the date of
notice of the damage or taking.  If PURCHASER  exercises  the right to terminate
this  Agreement  under this  Section  18, any  earnest  money  deposit  shall be
returned to PURCHASER  and this  Agreement  shall be null and void. If PURCHASER
does not elect to terminate this  Agreement,  there shall be no reduction of the
purchase price and at closing SELLER shall assign to PURCHASER all rights SELLER
may have with respect to any insurance proceeds or eminent domain award.

         20.      ENVIRONMENTAL INDEMNIFICATION.  It is hereby acknowledged that
PURCHASER shall not assume any  responsibility  or liability that may be imposed
upon SELLER by any state,  federal or local law,  rule,  regulation or ordinance
(including,   but  without  limitation,   any  requirement  to  report,  assess,
investigate,  abate and/or  remediate  the  PROPERTY)  resulting  from  SELLER'S
release of petroleum product or hazardous substance (as defined under CERCLA, 42
U.S.C.  ss.  9601 et seq.)  upon  the  PROPERTY  during  SELLER'S  ownership  or
operation of the PROPERTY,  and SELLER shall be responsible  for compliance with
any such  requirement,  if any. The SELLER  shall  indemnify  and hold  harmless
PURCHASER from any such claims, demands, penalties,  obligations and liabilities
(including, but without limitation,  PURCHASER'S reasonable attorneys' fees that
may be incurred in defense  thereof)  relating to or as a result of a release of
petroleum product or hazardous substance (as defined under CERCLA) of any nature
upon the PROPERTY  during  SELLER'S  ownership or operation of the PROPERTY,  as
well as such costs,  expenses,  or fees that may be  incurred if an  underground
storage tank ("UST"), or any portion of UST system is subsequently  located upon
the PROPERTY,  including,  but without limitation,  the expense of removing said
UST system and  closing  said UST system in  accordance  with  applicable  laws.
Provided PURCHASER  receives  satisfactory  indemnification  from Contractor (in
PURCHASER'S  sole and  absolute  discretion),  SELLER  shall  not be  liable  or
responsible  to PURCHASER for any acts or omissions of the  Contractor or any of
its  subcontractors  that may have  resulted  in the  release  or  discharge  of
petroleum  products or hazardous  substances on the PROPERTY  during or prior to
SELLER'S  ownership,  and PURCHASER  agrees to look solely to the Contractor and
its  subcontractors  for  any  loss,  cost  or  damage  arising  therefrom.  The
provisions of this Section 20 shall survive Closing.

         21.      FACILITY.  If  during  the Study  Period  or the Study  Period
Extension,  the  Phase  I  Environmental   Assessment,  or  site  investigation,
concludes that the PROPERTY is a facility, as defined by Section 20101.(1)(1) of
part 201 of the Michigan  Natural  Resources and  Environmental  Protection  Act
(hereinafter  referred to as "NREPA"),  1994, P.A. 451, as amended,  PURCHASER'S
obligation  to close  this  transaction  shall  be  expressly  conditioned  upon
PURCHASER'S, or its Assignee's, on or before the date of Closing, receipt (at no
cost or  expense  to  SELLER)  from  the  MDEQ  of all  approval  of a  Baseline
Environmental  Assessment to be submitted to the MDEQ pertaining to the PROPERTY
and the MDEQ's  determination  that  PURCHASER,  and/or its Assignee,  meets the
requirements  for an exemption from liability under Section 20126(1) of part 201
of NREPA;  and PURCHASER,  and/or its Assignee's,  receipt of a determination by
the MDEQ, the  sufficiency of same being in PURCHASER'S  sole  discretion,  that
PURCHASER'S  and/or  its  Assignee's,  proposed  use of the  PROPERTY  satisfies
PURCHASER'S,  and/or its Assignee's,  obligations under Section 20107(a) of Part
201 of NREPA. If the Phase I Environmental  Assessment and/or site investigation
concludes  that  the



                                       13


site is a facility, then the Closing Date for this transaction shall be extended
by sixty (60) days.  SELLER hereby grants to  PURCHASER'S  and/or its Assignee's
environmental  consultant  an easement  and license to come onto the PROPERTY to
conduct such investigation, including soil borings, as it determined necessary.

         22.      NOTICES.  Any  notices,  demands,  requests  or  communication

damages  (including,  but not limited to, attorneys' fees of counsel selected by
the indemnified party) resulting from the claims of any broker, finder, or other
