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

     As previously  discussed in the 1999 Annual Report on Form 10-K (1999 10K),
and the March 31, 2000 Quarterly Report on Form 10-Q (2000 10Q) of Constellation
Energy Group, Inc. (Constellation Energy) and Baltimore Gas and Electric Company
(BGE),  BGE's electric  generation was subject to  deregulation  pursuant to the
Electric  Customer Choice and  Competition Act of 1999 (the "Act").  On June 30,
2000, BGE received the approval of the Nuclear  Regulatory  Commission (NRC) for
the transfer of its nuclear  generation  assets. The NRC's approval was the last
regulatory  approval  needed by BGE to  transfer  all of its  generation  assets
including the electric generating  facilities,  fuel inventories,  materials and
supplies,  and certain power purchase  contracts to unregulated  subsidiaries of
Constellation  Energy.  In addition  to the NRC's  approval,  BGE also  received
approval to transfer  its  generation  assets from the Maryland  Public  Service
Commission  (Maryland  PSC),  the Federal Energy  Regulatory  Commission and the
Pennsylvania  Public  Utility  Commission,  and obtained a private letter ruling
from the Internal Revenue Service that the transfers would be tax free.

         Consequently,  effective  July 1, 2000,  BGE  transferred  its  nuclear
generating  assets and its  nuclear  decommissioning  trust fund and  reserve to
Calvert Cliffs Nuclear Power Plant, Inc. (CCNPP),  a subsidiary of Constellation
Energy.  BGE transferred its fossil  generating assets and its partial ownership
interest in two coal plants and a hydroelectric plant located in Pennsylvania to
Constellation  Power  Source  Generation,  Inc.  (CPSG),  also a  subsidiary  of
Constellation  Energy.  In total,  these generating assets represent about 6,240
megawatts of generation  capacity with a total  estimated net book value at June
30, 2000 of  approximately  $2.4  billion.  The exact amount of the  transferred
assets  will be based on the actual net book value at June 30,  2000,  which has
not been determined at the date of this filing.

     As part of the  transfer of the electric  generating  business to CCNPP and
CPSG, BGE transferred  tax-exempt debt of approximately $47 million to CCNPP and
$231  million to CPSG  related to the  transferred  assets.  Additionally,  CPSG
issued  approximately  $366  million  in  unsecured  promissory  notes  to  BGE.
Repayments of the notes by CPSG will be used  exclusively to service the current
maturities of certain BGE long-term debt. BGE also transferred equity associated
with the generating  assets to these entities.  The fossil fuel and nuclear fuel
inventories, materials and supplies, and certain purchase power contracts of BGE
were also assumed by these entities.

         Attached as an exhibit is pro forma financial  statements for BGE and a
description of the pro forma  adjustments that reflect these transfers and other
financial  impacts  surrounding the  deregulation  of BGE's electric  generation
business. These pro forma financial statements and descriptions of the pro forma
adjustments  represent the latest  available  information as of the date of this
report.

ITEM 5. Other Events
--------------------

     On April 8, 1999 Maryland  enacted the Act.  Major  elements of the Act are
discussed in our June 30, 1999  Quarterly  Report on Form 10-Q.  On November 10,
1999,  the  Maryland  PSC  issued  an  order  that  resolved  the  major  issues
surrounding  electric  restructuring,  accelerated  the  timetable  for customer
choice  and  addressed  the  major  provisions  of the Act  (the  "Restructuring
Order").  The  Restructuring  Order also  resolved  the  electric  restructuring
proceeding  (transition costs,  customer price protections,  and unbundled rates
for electric services) and a petition filed by the Office of People's Counsel to
lower BGE's electric base rates. The major provisions of the Restructuring Order
are discussed in our 2000 10Q.

         In early  December  1999,  the  Mid-Atlantic  Power Supply  Association
(MAPSA),  Trigen-Baltimore  Energy Corporation and Sweetheart Cup Company,  Inc.
filed  appeals  of the  Restructuring  Order,  which  were  consolidated  in the
Baltimore City Circuit Court. MAPSA also filed a motion to delay  implementation
of the Restructuring  Order,  pending a decision on the merits of the appeals by
the court.  Both the Trigen and  Sweetheart Cup appeals have been dismissed with
prejudice.

         In April 2000,  the  Baltimore  City Circuit  Court  dismissed  MAPSA's
appeal and denied its motion for a delay of the  Restructuring  Order.  In June,
2000,  MAPSA filed another motion with the Baltimore City Circuit Court to delay
implementation  of certain  provisions of the  Restructuring  Order. The Circuit
Court also denied that motion.  MAPSA then filed a motion for injunctive  relief
with the Maryland Court of Special Appeals,  which denied the motion on June 30,
2000.  MAPSA then  filed a petition  for  certiorari  and motion for  injunctive
relief with the  Maryland  Court of Appeals,  which  granted  the  petition  and
ordered a delay of the Restructuring  Order on June 30, 2000. The Maryland Court
of Appeals has set a hearing on MAPSA's  motion for July 20, 2000.  BGE filed an
emergency  motion for  reconsideration,  which was supported by the Maryland PSC
and Office of People's Counsel. However, the Court of Appeals deferred action on
the motion until its July 20, 2000 hearing.

         The effect of the Court of Appeals stay of the  Restructuring  Order is
to delay the implementation of customer choice in BGE's service territory. While
we believe that MAPSA's case is without  merit,  no assurance can be given as to
the timing, or outcome,  of the case. At this time, we cannot predict the effect
that the delay of  implementation  of customer  choice or MAPSA's  appeal on the
merits of the Restructuring Order will have on Constellation  Energy or BGE, but
they could have a material  adverse effect on  Constellation  Energy's and BGE's
financial results.

         On July 6, 2000, MAPSA and Shell Energy LLC filed, in the Circuit Court
for  Baltimore  City,  a petition for review and an  injunction  of the Maryland
PSC's order approving the transfer of BGE's generation assets issued on June 19,
2000.  We believe  that this  petition  and request for  injunction  are without
merit.  However,  we cannot predict the timing, or outcome,  of this case, which
could  have a  material  adverse  effect  on  Constellation  Energy's  and BGE's
financial results.
