Item 2. Acquisition or Disposition of Assets
- --------------------------------------------

     On August 12, 1999,  Registrant  completed the  acquisition of three office
buildings  (the  "Acquired  Buildings")  in the State of Indiana.  The  Acquired
Buildings  contain  an  aggregate  of  approximately  95,836  square  feet.  The
aggregate  purchase price for the Acquired  Buildings was $7,944,000,  which was
paid by assuming  approximately  $5,255,000  of existing  debt (the  "Debt") and
$116,400 of related escrow balances on the properties and issuing  approximately
541,600 shares of  Registrant's  common stock at the rate of $4.75 per share. In
conjunction  with the  assumption  of the  Debt,  Registrant  also  assumed  the
obligations and liabilities of the original guarantors of the Debt.

     The Acquired  Buildings were purchased from Sheridan Realty Partners,  L.P.
("Sheridan"), a Delaware limited partnership. The purchase price of the Acquired
Buildings was determined through negotiations between Registrant and Sheridan.

     As  required  pursuant  to the  terms of the  Purchase  And Sale  Agreement
between  Registrant and Sheridan  regarding the acquisition by Registrant of the
Acquired  Buildings,  Registrant has appointed  William T. Atkins and Charles K.
Knight to Registrant's Board Of Directors.

     Mr.  Atkins is the  President  and a 16.5% owner of Sheridan  Realty  Corp.
("Sheridan Realty"),  which is the general partner of Sheridan.  Sheridan Realty
holds a 1%  interest  in Sheridan  as the  general  partner,  and an  additional
3.1335% interest as a limited partner. In connection with the acquisition of the
Acquired Buildings,  Mr. Atkins received  approximately  33,000 of the shares of
common  stock paid by  Registrant  as a portion of the purchase  price.  A trust
company for which Mr. Atkins  serves as a director  serves as trustee for trusts
that received an aggregate of approximately  76,900  additional shares of common
stock.  Mr.  Atkins has no  beneficial  interest in any shares held by the trust
company.  Mr.  Knight did not receive any shares of common  stock as a result of
the acquisition.

     Registrant has hired Sheridan Development,  LLC ("Sheridan Development") to
manage the Acquired  Buildings for a one-year  term  commencing on July 1, 1999.
During that term,  Sheridan  Development is  responsible  for all aspects of the
management and operation of the Acquired  Buildings and coordinating the leasing
of the Acquired  Buildings.  In exchange,  Registrant  will pay a management fee
equal to 5% of the  gross  monthly  rental  income  received  from the  Acquired
Buildings.  Mr. Atkins is the co- manager,  President and a 25.05% owner and Mr.
Knight is a Vice President and 9.9% owner of Sheridan Development.

     Other than as described in this Item 2, there are no material relationships
between Sheridan and any of Registrant,  Registrant's  directors or officers, or
associates of Registrant's directors or officers.

              NOTES TO PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 1 - BASIS OF PRESENTATION

     The accompanying  unaudited pro forma consolidated financial statements are
     presented to reflect the  acquisition of the Keystone  Office  Buildings by
     AmeriVest.

     The accompanying pro forma consolidated  balance sheet as of March 31, 1999
     has been prepared to give effect to the  acquisition of the Keystone Office
     Buildings  as  if  the   acquisition   occurred  on  March  31,  1999.  The
     accompanying pro forma  consolidated  statements of operations  combine the
     historical  operations  of  AmeriVest  for the three months ended March 31,
     1999 and the year ended December 31, 1998 with the  historical  real estate
     operating  revenues and expenses of the Keystone  Office  Buildings for the
     three  months  ended March 31, 1999 and the year ended  December  31, 1998,
     respectfully,  and are presented as if the  acquisition had occurred at the
     beginning of each of the periods presented.

NOTE 2 - PRO FORMA ADJUSTMENTS

     The  unaudited  pro forma  consolidated  financial  statements  reflect the
     following pro forma adjustments:

     a)   Purchase price of Keystone Office Buildings.

     b)   Increase in mortgage  loan related to debt  assumed by  AmeriVest  for
          acquisition of Keystone Office Buildings,  $4,730,000 with interest at
          8% and $525,000 with interest at 8.63%.

     c)   Issuance of 541,593 shares of common stock, valued at $4.75 per share,
          as partial consideration for acquisition of Keystone Office Buildings.

     d)   Cash paid for additional costs of acquisition.

     e)   Capital improvement reserve.

     f)   Real estate taxes.

     g)   Depreciation  expense on Keystone Office Buildings to be recognized by
          AmeriVest.

     h)   Interest  expense to be  recognized  by AmeriVest  related to mortgage
          debt  assumed in  conjunction  with the  acquisition  of the  Keystone
          Office Buildings.

NOTES 3 - (LOSS) INCOME PER SHARE

     Pro forma  (loss)  income per common  share for the months  ended March 31,
     1999 and the year ended December 31, 1998 is computed based on the weighted
     average number of common shares  outstanding  during the periods,  assuming
     that the 541,593 shares issued in conjunction  with the  acquisition of the
     Keystone  Office  Buildings  were  issued at the  beginning  of each of the
     periods.
