         THIS ADDENDUM TO PURCHASE AGREEMENT (the "Addendum") is entered into as
of the 19th day of  September,  2001,  by and between  OPEN PLAN  SYSTEMS,  INC.
("Seller") and ENA DRIVE, L.L.C. ("Purchaser").


                              W I T N E S S E T H:
                              - - - - - - - - - -

         WHEREAS,  Seller  and  Purchaser  entered  into that  certain  Purchase
Agreement,  with an Effective Date as of August 21, 2001 (the "Agreement"),  for
the purchase and sale of the property described therein (the "Property"); and

         WHEREAS,  pursuant  to  Section  10 of  the  Agreement,  the  Agreement
provides  for a Closing  within 35 days of the  Effective  Date,  which  date of
Closing is September 25, 2001 (the "Closing Date"); and

         WHEREAS, the Study Period and all Study Period Extensions under Section
16 of the  Agreement  have expired and  Purchaser has not exercised its right to
terminate the Agreement thereunder; and

         WHEREAS,  in order to fund the Net Purchase Price through  financing to
be obtained  from  Michigan  National  Bank,  the  Purchaser  has  requested  an
extension of the Closing Date; and

         WHEREAS,  the  Seller  desires to grant such  request  pursuant  to the
following terms and conditions.

         NOW, THEREFORE,  for good and valuable  consideration,  the receipt and
sufficiency  of which are  hereby  acknowledged,  the  parties  hereto  agree as
follows:

         1.   The foregoing recitals are hereby incorporated herein.

         2.   All defined  terms  hereunder  shall have the same  meaning as set
forth in the Agreement unless otherwise defined herein.

         3.   Purchaser hereby acknowledges and agrees that (i) the Study Period
and all Study Period Extensions have expired,  (ii) all necessary due diligence,
inspections,  reviews and evaluations of the Property and the  transaction  have
been  performed  and  Purchaser  is  satisfied  with  the  results  of such  due
diligence,  inspections,  reviews and  evaluations,  and (iii) Purchaser has not
exercised its right to terminate  the Agreement  pursuant to Section 16 thereof,
and any right to terminate under Section 16 has lapsed.




         4.   Notwithstanding   anything  contained  in  the  Agreement  to  the
contrary,  the  Closing  Date shall be October 5, 2001 or such  earlier  date as
shall be mutually agreeable to the parties hereto. TIME IS OF THE ESSENCE.

         5.   Notwithstanding  Seller's  agreement  to extend the Closing  Date,
Purchaser  acknowledges  and agrees that its ability to obtain financing for the
purchase  of the  Property  is not,  and shall  not be or  become,  a  condition
precedent to Closing.

         6.   Seller  and  Purchaser  agree  that  the  form of  Assignment  and
Assumption Agreement attached hereto as Exhibit A is satisfactory to the parties
in all  respects,  and that except for  completion of the exhibits and execution
and delivery by the parties  thereto,  the attached  Assignment  and  Assumption
Agreement  otherwise  satisfies the requirements of Section 11(A)(3) and Section
17(A)(4)  of the  Agreement.  The parties  acknowledge  that  Purchaser  has not
received   satisfactory   environmental   indemnification  from  Contractor  (as
contemplated   by  Section  20  of  the   Agreement)   and  therefore   Seller's
indemnification  in Section  20 shall  remain in effect in  accordance  with the
terms thereof.

         7.   The  parties  hereby  ratify  and  agree  that the  Agreement,  as
modified by this Addendum, is in full force and effect. All terms and conditions
of the Agreement not amended by this Addendum shall remain in effect.

         8.   This  Addendum  may be executed  in two (2) or more  counterparts,
each of which shall be deemed an original  hereof,  but all of which,  together,
shall constitute a single agreement.

         IN WITNESS WHEREOF, Seller and Purchaser have executed this Addendum as
of the date and year set forth above.
