                 BGE PRO FORMA FINANCIAL STATEMENTS - GENERATION
                                 ASSET TRANSFER

BACKGROUND

As previously reported in our March 17, 2000 Report on Form 8-K (incorporated by
reference in our 1999 Annual Report on Form 10-K),  we presented  1999 pro forma
financial  statements for Baltimore Gas and Electric Company (BGE), a subsidiary
of Constellation Energy Group, Inc.  (Constellation  Energy). As a result of the
deregulation of BGE's electric  generation,  we expect BGE to transfer,  at book
value,  certain generation assets and liabilities to Calvert Cliffs,  Inc. (CCI)
and  Constellation   Generation,   Inc.  (CGI),   nonregulated  subsidiaries  of
Constellation  Energy,  no earlier than July 1, 2000 and upon the receipt of all
regulatory approvals.  The pro forma financial statements and description of the
pro forma  adjustments  reflect  these  transfers  and other  financial  impacts
surrounding the deregulation of BGE's electric generation  business.  We discuss
the deregulation of BGE's electric generation business further in this Quarterly
Report  on Form  10-Q in the  Electric  Restructuring  section  of  Management's
Discussion and Analysis and in our 1999 Annual Report on Form 10-K.

Since our 1999 Annual Report on Form 10-K,  there have been new  developments in
the assumptions used in these pro forma financial  statements.  Accordingly,  we
are providing  revised pro forma  financial  statements to reflect certain known
changes in the  assumptions.  These changes  primarily  result from the Internal
Revenue  Service's (IRS)  determination  that the issuance of certain  unsecured
notes would not qualify as a tax-free transaction.  Based on this determination,
we have  reduced the level of  unsecured  promissory  notes that BGE expected to
transfer to our nonregulated subsidiaries from $1.1 billion, as disclosed in our
1999 Annual Report on Form 10-K, to  approximately  $426 million.  Also, we have
updated our  estimates of other amounts to be  transferred  based on more recent
information.

The transfer of BGE's  generating  assets to CCI and CGI continues to be subject
to various conditions,  including the receipt of satisfactory  federal and state
regulatory approvals.  Nuclear Regulatory Commission approval of the transfer of
the operating  licenses of Calvert  Cliffs Nuclear Power Plant Units 1 and 2 and
of the decommissioning trusts will be necessary. We have filed for a ruling from
the IRS that the  transfer  of the  generation  assets,  including  the  nuclear
decommissioning  trusts,  and the  assignment  of BGE tax  exempt  debt  and the
revised  issuance of unsecured  promissory  notes by CCI and CGI, can occur on a
tax free basis.  Approvals from the Federal Energy  Regulatory  Commission,  the
Maryland PSC (PSC), and the Pennsylvania  Public Utility Commission will also be
required in conjunction with these transactions. There can be no assurance as to
the receipt of these or any other  regulatory  approvals or the actual timing of
the asset transfer.

DESCRIPTION OF PRO FORMA FINANCIAL INFORMATION

The  following  consolidated  financial  statements  for BGE are filed with this
Exhibit:

o    Unaudited Condensed Pro Forma Balance Sheet At March 31, 2000, and
o    Unaudited  Condensed Pro Forma Income Statement for the Year Ended December
     31, 1999 (Revised) and for the Three Month Period Ended March 31, 2000.

The following major assumptions were made in preparing these pro forma financial
statements:

o    The  transfers  described  above were assumed to occur as of March 31, 2000
     for the purposes of the condensed pro forma balance sheet.
o    The transfers  described  above were assumed to occur as of January 1, 1999
     for the purposes of the revised  condensed  pro forma income  statement for
     the year ended December 31, 1999. The transfers were assumed to occur as of
     January  1,  2000  for the  purposes  of the  condensed  pro  forma  income
     statement for the three-month period ended March 31, 2000. However, weather
     conditions can have a great impact on our results for interim periods. This
     means that results for interim periods do not necessarily represent results
     to be expected for the year.
o    The  transfer  of the  generating  assets  and  decommissioning  trusts was
     assumed to occur at book value and on a non-taxable basis.
o    The provisions of the PSC's Restructuring Order are assumed to be effective
     as of the beginning of each period presented for the purposes of developing
     BGE's revenues and electric  purchased fuel and energy expenses included in
     the condensed pro forma income statements.
o    An  effective  tax rate of  approximately  35% was  utilized to develop the
     income tax effects of adjustments to the revised condensed pro forma income
     statement  for the year ended  December 31, 1999.  An effective tax rate of
     approximately  39.55% was utilized for the  three-month  period ended March
     31,  2000.  The  difference  in the  effective  tax rate  results  from the
     comprehensive changes in the state and local tax laws that began January 1,
     2000. We discuss these  comprehensive tax law changes in Note 4 of our 1999
     Annual Report on Form 10-K.

These pro forma financial statements have been prepared for comparative purposes
only and do not  purport  to be  indicative  of the  results  of  operations  or
financial  condition  which would have actually  resulted if the transfer of the
generation  assets or other related  transactions  had been made on the dates or
for the periods presented, or which may result in the future. Further, these pro
forma financial statements have been prepared using information available at the
date  of  this  filing.  As a  result,  certain  amounts  indicated  herein  are
preliminary in nature and, therefore, are subject to change in the future.

DESCRIPTION OF PRO FORMA ADJUSTMENTS

The Unaudited Condensed Pro Forma Income Statements and Balance Sheet filed with
this Exhibit reflect the following adjustments:

Income Statements Adjustments

1.   The  expected  reduction  of BGE's  revenues  to  remove  $112  million  of
     interchange  and other wholesale sales for the year ended December 31, 1999
     ($23 million for the three-month  period ended March 31, 2000),  which will
     no longer be a part of its business once electric deregulation occurs.
2.   The adjustment of BGE's revenues to reflect the $54 million average, annual
     residential rate reduction provided for in the Restructuring  Order for the
     year ended December 31, 1999 ($13 million for the three-month  period ended
     March 31, 2000).
3.   The  anticipated  transfer to CCI of  approximately  $164  million of BGE's
     revenues that will fund nuclear  decommissioning and stranded costs for the
     year ended December 31, 1999 ($40 million for the three-month  period ended
     March 31, 2000).
4.   The reversal of BGE's actual  electric fuel and  purchased  energy costs of
     approximately  $487  million  for the year ended  December  31,  1999 ($119
     million  for  the  three-month  period  ended  March  31,  2000),  and  its
     replacement  with the estimated $1,187 million cost of power BGE would have
     purchased  from  CPS to meet its  system  sales  load  for the  year  ended
     December 31, 1999 ($267 million for the three-month  period ended March 31,
     2000) at standard  offer  service rates  provided for in the  Restructuring
     Order.
5.   The expected elimination of operation and maintenance expenses directly and
     indirectly relating to the generation function for the respective period.
6.   The anticipated  elimination of approximately $165 million of depreciation,
     amortization,   and  nuclear   decommissioning   expense  relating  to  the
     transferred  assets for the year ended December 31, 1999 ($42.5 million for
     the three-month period ended March 31, 2000).
7.   The  removal  from  results of the  nonrecurring  impact of $75  million of
     amortization  expense  relating to the $150  million  reduction of electric
     generation  plant that will  occur  prior to the  actual  generation  asset
     transfer  under the  terms of the  Restructuring  Order for the year  ended
     December 31, 1999 ($37.5 million for the three-month period ended March 31,
     2000).
8.   The estimated reduction to taxes other than income taxes resulting from the
     transfer of the generation function for the respective period.
9.   The reduction to other income associated with the elimination of the equity
     portion of the  allowance  for funds used during  construction  relating to
     generation  construction  projects,  equity in the  earnings of Safe Harbor
     Water   Power   Corporation,   and   after-tax   earnings  on  the  nuclear
     decommissioning trusts.
10.  The  reflection  in other income of  approximately  $26 million of interest
     income expected to be earned on the unsecured promissory notes described in
     this  Exhibit  for the year ended  December  31,  1999 ($7  million for the
     three-month period ended March 31, 2000).
11.  The reduction of fixed charges to approximate  interest expense expected to
     be avoided on the transferred tax-exempt debt.

     which are expected to be transferred  along with the associated  generation
     assets.
                                        3



Balance Sheet Adjustments

     generation asset transfer under the terms of the Restructuring Order.
7.   The   expected   reduction   to  current   liabilities   from   eliminating
     approximately  $4 million of accrued  interest  relating to the transferred
     tax-exempt debt described in this Exhibit.
