Investors 4 (the "Partnership"),  the subject company, at a purchase price equal
to $250 per Unit,  less the amount of any  distributions  declared  or made with

reduction for  distributions  made or declared prior to the Expiration Date. Any
distributions  made or declared after the  Expiration  Date, by the terms of the
Offer  and as set forth in the  Letter  of  Transmittal,  would be  assigned  by
tendering Unit holders to the  Purchasers.  MacKenzie  Patterson  Fuller,  LP is
named as a bidder herein because it is deemed to control the Purchasers,  but is
otherwise not participating in the offer described in this schedule.

      In  the  event  of  a  price   reduction   resulting  from  a  Partnership
distribution  declared  or made after the Offer  Date and before the  Expiration
Date, as described above, the Purchasers will file an amendment to this Schedule
TO  reflecting  such  reduction and will,  to the extent  necessary,  extend the
Expiration  Date to assure there is a minimum ten business day period  following
the amendment before the Offer expires.

      Tender of Units will  include  the tender of any and all  securities  into
which the Units may be converted and any securities  distributed with respect to
the Units from and after the Offer Date.

Units as of DECEMBER 31, 2006,  according to its Annual  Report on Form 10-K for
the fiscal year ending  December 31, 2006. The  Purchasers and their  affiliates
currently  beneficially  own 6 Units,  or 0.01% of the  outstanding  Units.  The
12,000  Units  subject to the Offer  constitute  20% of the  outstanding  Units.
