                          WASHINGTON GAS LIGHT COMPANY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

NOTE 1--GENERAL

         ACCOUNTING MATTERS

         These  notes  are an  integral  part of the  accompanying  consolidated
financial  statements of Washington Gas Light Company  (Washington  Gas Light or
the Company) and its subsidiaries. In the opinion of Washington Gas Light, these
financial statements, including the notes hereto, reflect all adjustments (which
include only normal recurring adjustments) necessary for a fair statement of the
results for the periods  presented.  These financial  statements  should be read
together with  Washington  Gas Light's Annual Report on Form 10-K for the fiscal
year ended September 30, 1999.  Certain  amounts in the financial  statements of
prior years have been reclassified to conform to the presentation of the current
year.

         Due to the seasonal  nature of  Washington  Gas Light's  business,  the
results of operations  shown do not indicate the expected results for the fiscal
year ended September 30, 2000.

         USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

         In accordance with generally accepted accounting principles, management
makes estimates and  assumptions  regarding:  1) reported  amounts of assets and
liabilities;  2) disclosure of contingent  assets and liabilities at the date of
the  financial  statements;  and 3) reported  amounts of revenues  and  expenses
during the reporting period. Actual results could differ from those estimates.

NOTE 2--RESTRUCTURING AND RELATED ORGANIZATIONAL CHANGES

         CORPORATE STRUCTURE

         At its March 3, 2000,  Annual Meeting of  Shareholders,  Washington Gas
Light's shareholders voted to form a holding company known as WGL Holdings, Inc.
(WGL Holdings). Under the new structure,  Washington Gas Light, as the regulated
utility,  and the subsidiaries it currently holds, will each operate as separate
subsidiaries  of WGL Holdings,  Inc. WGL Holdings and  Washington  Gas Light are
taking the necessary steps to have the new structure in place this summer. These
steps include approval by the State  Corporation  Commission of Virginia (SCC of
VA) and the approval of an  application  that has been filed with the Securities
and Exchange Commission.

         Upon the effective date of the reorganization,  certificates previously
representing  shares of  Washington  Gas Light common  stock will  automatically
represent  the same  number  of  shares of WGL  Holdings  common  stock and will
entitle  the  holder  to  receive  a  certificate  of WGL  Holdings.  After  the
reorganization,  all serial  preferred stock of Washington Gas Light will remain
issued and outstanding as shares of Washington Gas Light serial preferred stock.
The  dividend  rate for the  preferred  stock  will  not be  changed  and  those
dividends will continue to be paid by Washington Gas Light.

                                      - 7 -



         All outstanding  indebtedness  and other  obligations of Washington Gas
Light  will  remain  as   obligations   of   Washington   Gas  Light  after  the
reorganization.  Immediately after the consummation of the merger, WGL Holdings,
Inc. will have no  outstanding  securities  other than common  stock,  but could
issue  other  securities  in  the  future.   Holders  of  Washington  Gas  Light
medium-term notes will continue as security holders of Washington Gas Light.

         SUBSIDIARY MERGERS

         Shenandoah Gas  Company--On  September 29, 1999, the Company's Board of
         -----------------------
Directors  authorized a merger of a Company  subsidiary,  Shenandoah Gas Company
(Shenandoah),  into  Washington Gas Light to form a single  corporation  for the
regulated  distribution  of natural  gas. On December  22,  1999,  the SCC of VA
issued an order that approved the merger  request,  but required that Shenandoah
continue to operate as a division  with  separate  accounting  records until the
Company files, and the SCC of VA approves,  a plan for the merger of the tariffs
for  Washington  Gas Light and  Shenandoah.  In the  interim,  the Company  must
continue  to  fulfill  longstanding   regulatory   reporting   requirements  for
Washington Gas Light and Shenandoah as separate entities.

         Certificates  of  Merger  were  issued  by  the  District  of  Columbia
Department of Consumer and Regulatory Affairs,  effective March 22, 2000, and by
the SCC of VA,  effective  April 1, 2000.  Shenandoah was merged into Washington
Gas Light effective April 1, 2000.

         Virginia Intrastate Pipeline  Company--Effective  December 28, 1999, an
         -------------------------------------
inactive Company  subsidiary,  Virginia  Intrastate Pipeline Company (VIPCo) was
merged into  Washington Gas Light.  VIPCo was originally  organized to construct
and operate a natural gas  pipeline.  Construction  of the proposed  project was
subsequently cancelled and, as a result, VIPCo has been inactive for a number of
years. VIPCo was inactive at the time of the merger.

         NEW SUBSIDIARY

         In January 2000, the Company  established WG Maritime Plaza I, Inc. (WG
Maritime),  to hold  Washington  Gas  Light's  interest  in a venture  formed to
develop a 12-acre parcel of land in Southeast Washington,  D.C. that the Company
has owned since 1888. In May 1999, the Company announced its intention to pursue
commercial  development of this site in partnership  with a national  developer.
The  Company is  proposing  to lease the site to the  venture  under a long-term
ground  lease and to receive a carried  interest.  The Company  will not play an
active role in any  development  or  management  activities.  The Company is not
contributing  any  capital to this  venture.  WG  Maritime  is a  subsidiary  of
Washington  Gas Resources,  Corp.,  a wholly owned  subsidiary of Washington Gas
Light that serves as the parent  company for most of the  Company's  non-utility
subsidiaries.  No expenditures  were made by WG Maritime through March 31, 2000,
and future expenditures by WG Maritime are not expected to be material.

         DISPOSITION OF WEST VIRGINIA ASSETS

         In  November  1998,  Shenandoah  entered  into  an  agreement  to  sell
virtually all of its natural gas utility  assets  located in West  Virginia.  At
that time, the Company recorded an estimated  pre-tax loss of $3.3 million ($2.1
million  after-tax).  When the sale was consummated on July 1, 1999, the Company
reduced  the  pre-tax  loss by $0.4  million  for a net  pre-tax  loss  from the
transaction of $2.9 million, or $1.9 million after-tax.

         The  new  owner  is  serving  Shenandoah's  former  3,800  natural  gas
customers in Martinsburg and Berkeley County, West Virginia. To ensure continued
natural gas service in the Eastern

                                      - 8 -



Panhandle  of West  Virginia,  the  Shenandoah  division  provides  natural  gas
transportation service to the new owner. Shenandoah continues to provide natural
gas service to more than 11,000 customers in the northern  Shenandoah  Valley of
Virginia.

NOTE 3--LONG-TERM DEBT

         UNSECURED MEDIUM-TERM NOTES

         The Company issues  unsecured  Medium Term Notes (MTNs) whose terms are
individually set as to interest rate, maturity and any call or put option. These
notes can have maturity dates of one or more years from date of issuance.

     On April 3, 2000,  Washington  Gas Light  issued  $8,500,000  of MTNs at an
interest rate of 7.5 percent. The notes mature on April 1, 2030, but the holders
have the option to put these notes to the Company  over the 30-day  period prior
to April 1, 2010.

         On April 6, 2000, the Company issued  $4,000,000 of MTNs at an interest
rate of 7.5 percent, with a maturity date of April 6, 2010.

         INTEREST RATE HEDGES AND DEBT ISSUANCES

         At March 31, 2000,  the Company had no interest  rate hedge  agreements
outstanding in connection with planned issuances of MTNs.  However, at March 31,
1999, the Company had one interest rate hedge agreement outstanding. The Company
accounts for its hedging  agreements as hedges of  anticipated  transactions  in
accordance with Statement of Financial  Accounting  Standards No. 80, Accounting
for Futures Contracts.

         During  October  1998,  the Company  issued $25 million of 10-year MTNs
with a coupon rate of 5.49  percent.  During June 1998,  in order to lock in the
Treasury  yield for this  issuance,  the Company  entered into an agreement that
reflected a forward sale of $24.9  million of 10-year U.S.  Treasury  notes at a
fixed price. The Company unwound its hedge position concurrent with the issuance
of the  above-mentioned  $25 million of MTNs.  The $2.1 million that the Company
paid  associated  with the  settlement  of this hedge  agreement was recorded to
unamortized  debt issuance costs in October 1998 and is being amortized over the
life of the MTNs. The effective cost of the debt was 6.74 percent.

         During  September  1998, in order to lock in the Treasury  yield for an
anticipated $39 million MTN issuance  related to the refunding of $39 million of
8-3/4 percent First  Mortgage  Bonds in July 1999,  the Company  entered into an
agreement  that  reflected  the  forward  sale of $40  million of  10-year  U.S.
Treasury notes at a fixed price to be paid on July 1, 1999. The Company  unwound
its hedge position  concurrent with the issuance of $50 million of MTNs in early
July 1999. The Company  received $2.0 million  associated with the settlement of
this hedge  agreement,  which it  recorded as a reduction  to  unamortized  debt
issuance  costs.  This benefit is being amortized over the life of the MTNs. The
effective cost of the debt was 6.31 percent.

NOTE 4--COMMON STOCK, PREFERRED STOCK AND EARNINGS PER SHARE

         SALE OF COMMON STOCK

         On November 12, 1998, the Company  publicly  offered two million shares
of common stock at $25.0625 per share.  On November 18, 1998,  the  underwriters
involved in the  offering  exercised  their  option to  purchase  an  additional
300,000  shares  from the Company at the same price per share.  Net  proceeds of
$55.7  million  were used for  general  corporate  purposes,  including  capital
expenditures.

         EARNINGS PER SHARE

         Basic  earnings  per share (EPS) is  computed  by  dividing  net income
applicable  to common  stock by the  weighted-average  number  of common  shares
outstanding  during the reported  period.  Diluted EPS assumes the conversion of
convertible  preferred  stock and the  issuance  of common  shares  pursuant  to
stock-based  compensation  plans at the beginning of the applicable  period. The
following  tables  show the  computation  of basic and diluted EPS for the three
months and six months ended March 31, 2000 and 1999.

NOTE 5--STOCK-BASED COMPENSATION

         The Company  periodically  provides  compensation in the form of common
stock to key employees and Company directors. The stock-based compensation plans
are  designed  to  promote  the  Company's   long-term  success  by  attracting,
recruiting and retaining key employees, and giving certain employees and Company
directors an ownership  interest in Washington  Gas Light,  thereby  promoting a
closer  identity  of  interests  between  those  individuals  and the  Company's
stockholders. The following sections describe stock awarded under these plans.

         STOCK GRANTS TO DIRECTORS

         Non-employee  directors  receive a portion of their annual retainer fee
in the form of common stock through the Directors' Stock  Compensation  Plan. On
January  3,  2000,  a total of 5,600  shares of  common  stock  was  granted  to
directors from the Company's  treasury stock. The fair value of the common stock
on the grant date was $26.25 per share.


NOTE 6--ENVIRONMENTAL MATTERS

         The Company has identified up to ten sites where  Washington Gas Light,
its  subsidiaries,  or their  predecessors  may have operated  manufactured  gas
plants (MGP).  The Company last used any such plant in 1984. In connection  with
these  operations,  the  Company is aware that  certain  by-products  of the gas
manufacturing  process  are  present  at or near  some  former  sites and may be
present at others.

         At one of the former MGP sites,  studies  show the presence of coal tar
under the site and an adjoining  property.  The Company's risk assessment  study
performed on the site shows that there is no  unacceptable  risk to human health
or the  environment.  The Company  has taken  steps to control  the  movement of
contaminants  into an adjacent river by installing a water treatment system that
removes and treats  contaminated  groundwater at the site. The Company  received
approval from governmental authorities for a comprehensive remedial plan for the
majority of the site that will allow  commercial  development  of the  Company's
property.  The  Company  has  signed a  development  agreement  with a  national
developer  to  enter a  ground  lease  and  obtain  a  carried  interest  in the
commercial  development.  Financing  for the project is  pending.  Approval of a
remedial  plan for the  remainder  of the site,  which  consists of an adjoining
property owned by a separate entity, is expected soon.

         At another former MGP site, a local government has notified the Company
about the  detection of a substance in an adjacent  river that may be related to
this  site.  This  same  local  government  owned and  operated  the MGP for the
majority  of the  life of the  plant.  The  local  government  sold the  MGP  to

                                        - 12 -


a company,  which was subsequently merged into Washington Gas Light.  Washington
Gas Light retired the MGP many years ago. In addition, the Company is aware that
the local government has had communications about this  condition  with  federal
environmental  authorities.   At  this  time,  the  extent  and  nature  of  the
contamination  and the  Company's  related  obligation,  if any,  to  perform or
contribute  to  remediation  cannot  be  determined.   The  Company  is  holding
discussions  with the local  government and may participate in studies to assess
the  extent  and nature of  contamination,  as well as the need for  appropriate
remediation.

         See Note 9 to the Consolidated  Financial  Statements in the Washington
Gas Light  Company 1999 Annual Report on Form 10-K for a discussion of the other
eight sites.


NOTE 7--COMMITMENTS AND AND CONTINGENCIES

         MARYLAND REGULATORY MATTERS

         On January 6, 2000, the Company announced that it filed with the Public
Service  Commission  of Maryland (PSC of MD or the  Commission) a  non-unanimous
settlement  agreement that would,  if approved by the  Commission,  freeze basic
delivery  rates at the  present  levels and  insulate  Maryland  customers  from
potential  rate increases over the next five years.  The only  adjustments  that
could occur would be for material changes in costs due to extraordinary  events,
such as tax rate changes or new  regulatory  requirements.  The  agreement  also
included  the  potential  to reduce  customers'  bills and  increase  returns to
shareholders through the use of an earnings-sharing  mechanism. In addition, the
agreement  included a provision for  residential  heating  customers  that would
reduce fluctuations in customers' bills due to the effects of weather deviations
from normal levels.

         On April 28, 2000,  the hearing  examiner  assigned to this  proceeding
issued a "Proposed Order of Hearing Examiner"  (Proposed Order) which recommends
that the PSC of MD reject the proposed settlement.  This recommendation is based
upon the hearing  examiner's  conclusion that the settlement does not adequately
address historical  disproportionate rates of return among classes of customers.
The  Proposed  Order will become a final Order of the PSC of MD on May 30, 2000,
unless either a party to the  proceeding  files an appeal with the Commission or
the Commission modifies or reverses the Proposed Order. At the present time, the
Company intends to file an appeal with the Commission.


         DISTRICT OF COLUMBIA REGULATORY MATTERS

         On February 17, 2000, the District of Columbia's Office of the People's
Counsel  (OPC)  filed a  complaint  with the Public  Service  Commission  of the
District of Columbia (PSC of DC) requesting an investigation  into the rates and
charges of  Washington  Gas Light.  The  complaint  alleges  that: 1) the actual
return on equity earned by  Washington  Gas Light is  significantly  higher than
authorized  by the PSC of DC;  and 2) the  return on  equity  that the PSC of DC
authorizes  Washington  Gas Light to earn is higher than is  appropriate,  given
current economic conditions.

         On February 28, 2000, Washington Gas Light submitted an "Answer" to the
PSC of DC requesting  the dismissal of the OPC complaint  chiefly on the grounds
that the OPC's analysis of the Company's  rates was  substantively  flawed.  The
Company  is in the  process of  responding  to  questions  made by the PSC of DC
Staff.  The  Company  is unable to  predict  when or how the PSC of DC will take
action on the complaint filed by OPC.

         Furthermore,  on May 12, 2000, OPC filed a motion  requesting  leave to
reply to  Washington  Gas Light's  Answer and a reply to the  Company's  Answer,
asserting that  Washington Gas Light's Answer

                                        - 13 -



failed to demonstrate  that  a rate investigation is unnecessary and once  again
is asking the PSC of DC to open an  investigation.  The Company  has  10 days to
file a reply.

NOTE 8--OPERATING SEGMENT REPORTING

         The Company reports four operating  segments:  1) regulated utility; 2)
energy  marketing;   3)  heating,   ventilating  and  air  conditioning   (HVAC)
activities; and 4) customer financing.

         With nearly 95 percent of the Company's  assets,  the regulated utility
segment is the Company's core business.  The regulated  utility segment provides
regulated  gas  distribution  services  (including  the purchase and delivery of
natural  gas,  meter  reading,   responding  to  customer  inquiries,  and  bill
preparation),  to  customers  in  metropolitan  Washington,  D.C.  and  parts of
Maryland and Virginia.  The energy marketing  segment sells natural gas directly
to  customers,  both  inside  and  outside  the  Company's  traditional  service
territory,  in competition  with  unregulated  gas  marketers.  The HVAC segment
designs,  renovates  and  services  mechanical  heating,   ventilating  and  air
conditioning  systems for commercial  and  residential  customers.  The customer
financing  segment  provides  financing  for  consumer  purchases of natural gas
appliances  and  energy-related  equipment.  Operating  segment  information  is
presented in the following table.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

         Certain  matters  discussed  in  this  report,   excluding   historical
information,  include  forward-looking  statements.  Words,  including,  but not
limited  to,  "estimates,"  "expects,"   "anticipates,"  "intends,"  "believes,"
"plans," and variations of these words, identify forward-looking statements that
involve  uncertainties  and risks.  These statements are necessarily  based upon
various assumptions with respect to the future, including:

       1) economic, competitive, political and regulatory conditions and
          developments;

       2) capital and energy commodity market conditions;

       3) changes in relevant laws and regulations, including tax, environmental
          and employment laws and regulations;

       4) weather conditions;

       5) legislative, regulatory and judicial mandates and decisions;

       6) timing and success of business and product development efforts;

       7) technological improvements;

       8) the pace of deregulation efforts and the availability of other
          competitive alternatives; and

       9) other uncertainties.

         Such   uncertainties  are  difficult  to  predict  accurately  and  are
generally  beyond the Company's direct control.  Accordingly,  while it believes
that  the  assumptions  are  reasonable,  the  Company  cannot  ensure  that all
expectations and objectives will be realized.  Readers are urged to use care and
consider  the risks,  uncertainties  and other  factors  that  could  affect the
Company's  business as  described  in this  Quarterly  Report on Form 10-Q.  All
forward-looking  statements made in this Quarterly Report on Form 10-Q rely upon
the safe harbor  protections  provided under the Private  Securities  Litigation
Reform Act of 1995.

         This  Management's  Discussion and Analysis of Financial  Condition and
Results  of  Operations  should  be  read  in  conjunction  with  the  Company's
Consolidated Financial Statements and Notes thereto.

RESULTS OF OPERATIONS

         THREE MONTHS ENDED MARCH 31, 2000 VS. MARCH 31, 1999

         EARNINGS
         --------

         For the quarter ended March 31, 2000,  net income  applicable to common
stock totaled  $64.9  million,  or $0.4 million  higher than the results for the
same period last year.  Basic and diluted  earnings per average  common share in
the current  quarter were $1.40 and $1.39,  respectively,  compared to basic and
diluted  earnings  per share of $1.39 for the same  quarter in

                                        - 16 -


fiscal  year 1999.  Results  for  the  quarter ended March 31, 2000,  included a
nonrecurring gain of $0.02 per average common share associated  with  the  sales
of two minor non-utility investments.

         There were 7.9 percent  fewer  degree  days during the current  quarter
compared  with the same  quarter  last year.  However,  the  Company was able to
increase its basic  earnings per share because of a 2.9 percent  increase in its
customer  base, a 7.6 percent  reduction in utility  operation  and  maintenance
expenses  and  continued   profitable  growth  by  its   energy-related   retail
activities.

         Reductions  in utility  operation  and  maintenance  expenses  enhanced
earnings per average  common share by $0.05 over the same quarter last year.  In
total,  utility operation and maintenance expenses fell by $3.9 million to $47.2
million,  primarily  due to the absence of expenses in the current  quarter from
the Company's former West Virginia operations,  reductions in bad debt expenses,
and the postponement of some operating activities from the current quarter until
later  in  the  fiscal  year.  A  $1.6  million  increase  in  depreciation  and
amortization  expenses,  resulting  primarily  from  the  completion  of  a  new
enterprise-wide  software  system  during the second  half of fiscal  year 1999,
reduced earnings by $0.02 per average common share.

         The Company's  major  non-utility  operations  earned $0.09 per average
common share in the quarter ended March 31, 2000,  compared to $0.04 in the same
quarter of last year. The increase was primarily attributable to improvements by
the unregulated  energy marketing  segment and the heating,  ventilating and air
conditioning  (HVAC) segment,  as well as the $0.02  nonrecurring  gain from the
sale of minor non-utility investments.

         NET REVENUES
         ------------

         Net  revenues for the quarter  ended March 31, 2000,  decreased by $4.9
million  (2.7  percent)  from the same  period  last year to $176.6  million and
reduced  earnings per average common share by $0.06 from the quarter ended March
31, 1999. As shown in the following  table, a 3.3 percent increase in the number
of customers served by the Company's continuing operations,  partially offset by
7.9 percent  warmer  weather,  resulted in a 1.3 percent  increase in firm therm
deliveries by the Company's  continuing  operations.  Nonetheless,  net revenues
decreased  primarily because of the absence of approximately $2.0 million of net
revenues in the current quarter from the West Virginia operations that were sold
in  July  1999,  as  well as a 19.1  percent  decline  in  therm  deliveries  to
interruptible  customers  served  by the  Company's  continuing  operations.  In
addition,  on a per therm basis, net revenues earned by the Company on wholesale
gas  deliveries  to the new  owner  of the  West  Virginia  utility  assets  are
significantly lower than those earned on direct sales and deliveries to the West
Virginia  customers  during  fiscal  year  1999,  reflecting  a  lower  cost  of
delivering  gas on a  wholesale  basis.  The lower  price  per  therm  earned on
deliveries  to the  wholesale  provider of the  Company's  former West  Virginia
customers  reduced the Company's net revenues by  approximately  $2 million from
the quarter ended March 31, 1999.

        Gas Delivered to Firm Customers

         The level of gas  delivered to firm  customers  is highly  sensitive to
weather  variability,  because a large  portion of the  Company's  deliveries of
natural gas is used for space heating.  The Company's  rates are based on normal
weather  and none of the  tariffs  for the  jurisdictions  in which the  Company
operates  currently  have a provision for weather  normalization.  However,  the
Company  does  have   declining   block  rates  in  its  Maryland  and  Virginia
jurisdictions that reduce the impact that deviations from normal weather have on
net revenues.  See the discussion below under "Regulatory  Matters" with respect
to proposed  tariff  changes in Maryland  that  include a weather  normalization
provision.

         During the three  months ended March 31,  2000,  firm therm  deliveries
rose by 826,000  therms or 0.2 percent  over the same  quarter  last year.  This
increase  primarily reflects a 3.3 percent rise in the number of customer meters
from  continuing  operations,  partially  offset by the  absence  of sales  this
quarter  to  nearly  3,800  customers  of the  Company's  former  West  Virginia
operations.  Firm therm deliveries were also adversely affected by a 7.9 percent
decrease  in heating  degree days from last

                                        - 18 -


year.  Weather for the three months ended March 31, 2000, was 8.5 percent warmer
than normal,  while weather for the same period last year was 1.2 percent warmer
than normal.

         As an  increasing  number of  customers  choose to buy the  natural gas
commodity from third-party  suppliers,  the volume of firm therm deliveries from
continuing  operations  to customers who purchase both the natural gas commodity
and delivery service as a "bundled"  service from Washington Gas Light decreased
from 437.7  million  therms in the three  months  ended  March 31, 1999 to 368.7
million therms during the current  quarter,  or a decline of 15.8 percent.  This
decrease  was more than  offset as the volume of firm gas  delivered  for others
from the Company's continuing  operations rose from 87.1 million therms to 163.0
million therms, an 87.1 percent increase.  On a per unit basis, the net revenues
that  Washington Gas Light earns from  delivering gas for others are the same as
it earns from bundled gas sales in which customers purchase both the natural gas
commodity and the associated delivery service from the Company.  Therefore,  the
Company  does not  experience  any loss of  margins  when  customers  choose  to
purchase their gas from a third-party supplier.

         Gas Delivered to Interruptible Customers

         Deliveries to  interruptible  customers  during the quarter ended March
31, 2000,  decreased by 24.7 million therms or 21.4 percent from the same period
last year, primarily because of decreased demand by interruptible  customers and
the absence of interruptible  gas deliveries during the current quarter from the
Company's former West Virginia  operations.  The effect on net income of changes
in  delivered  volumes and prices to the  interruptible  class is  minimized  by
margin-sharing arrangements embedded in the Company's interruptible rate design.
Under these  arrangements,  the Company applies a majority of the margins earned
on interruptible  gas sales and deliveries to firm customers' rates. This occurs
once the Company reaches a  pre-established  gross margin threshold or occurs in
exchange  for  shifting  many of the fixed costs of  providing  service from the
interruptible to the firm class.



         Gas Delivered for Electric Generation

         The Company sells and/or delivers gas to two companies that use natural
gas to fuel their  electric  generation  facilities  in Maryland.  Deliveries to
these  customers in the current  quarter  increased by 11.3 million therms (69.4
percent)  over the same  period  last year.  The  Company  shares a  significant
majority of the margins earned from gas deliveries to these  customers with firm
customers.  Therefore,  changes in the volume of interruptible gas deliveries do
not have a material effect on either net revenues or net income.

         OTHER UTILITY OPERATING EXPENSES
         --------------------------------

         Operation and maintenance expenses for the three months ended March 31,
2000,  declined by $3.9 million (7.6 percent) from the prior year's levels. This
reduction  improved  earnings  per average  common  share by $0.05 over the same
quarter of last year. The results for the quarter ended March 31, 1999, included
$2.6 million of operation and  maintenance  expenses  from the Company's  former
West Virginia operations.  Other key factors that contributed to the variance in
operation  and  maintenance  expenses  for this quarter  compared  with the same
quarter last year include:

                                         - 19 -


        o    a $2.3 million reduction in pension and postretirement  medical and
             life insurance benefits, a quarterly  reduction that is expected to
             continue through the remainder of fiscal year 2000;

        o    a $1.8 million reduction in bad debt expense,  which  resulted from
             the Company's continuing  improvements to its collection practices;
             and

        o    a $1.9  million  increase in labor  expense  over the same  quarter
             last year,  primarily  reflecting  increases in employee wages  and
             incentives,  partially  offset  by a 4.1 percent  reduction  in the
             number of utility employees.

         The current  quarter  reflects  the absence of some  expenses  that are
likely to be delayed  until  subsequent  quarters  of the current  fiscal  year.
Although  operation  and  maintenance  expenses for  subsequent  quarters of the
current fiscal year are likely to be higher than the quarter just completed, the
Company  anticipates that such expenses for all of fiscal year 2000 will be less
than the level incurred for all of fiscal year 1999.

         Depreciation and amortization  increased by $1.6 million (11.1 percent)
in  the  current  quarter  because  of the  Company's  increased  investment  in
property, plant and equipment.  This caused earnings per average common share to
fall by $0.02 when  compared  to the same  quarter  last year.  Included in this
increase  is $1.0  million  of  amortization  related  to the  completion  of an
enterprise-wide  software  system in the second half of fiscal year 1999.  Going
forward, the quarterly amortization  associated with this system should continue
to approximate this amount.

         Utility income taxes decreased by $1.7 million,  primarily due to a 4.7
percent decline in pre-tax utility  operating  income this quarter.  For utility
operations,  the  effective  income tax rates were 36.8  percent  for the second
fiscal quarters of both 2000 and 1999.


         NON-UTILITY RESULTS
         -------------------

         The Company has three primary unregulated operating segments: 1) energy
marketing;  2)  HVAC;  and  3)  customer  financing.   The  results  from  those
operations, plus the impact of other incidental unregulated activities increased
net operating income (after income taxes,  but before interest  expense) by $2.3
million from the same period last year to $4.3  million in the current  quarter.
After  applicable  interest  expense,  earnings per average common share derived
from non-utility  activities were $0.09 in the current  quarter,  an increase of
$0.05 over the same quarter  last year.  The  increase in  non-utility  earnings
includes  a  nonrecurring  gain  of  $0.02  per  average  common  share  from  a
subsidiary's sales of certain venture funds and a preferred stock interest.  The
following  table  compares  the  financial  results,  after  taxes and  interest
expense,  from non-utility  activities for the quarters ended March 31, 2000 and
1999.

         Energy Marketing

         The Company's retail energy marketing subsidiary, Washington Gas Energy
Services  (WGEServices),  sells  natural  gas in  competition  with  unregulated
marketers and unregulated  subsidiaries of other utility companies.  WGEServices
continued to expand rapidly as the subsidiary sold 18.4 billion cubic feet (bcf)
of gas in the current quarter, an increase of 20.3 percent from 15.3 bcf sold in
the second quarter of fiscal year 1999. During the quarters ended March 31, 2000
and 1999,  respectively,  22.7 percent and 20.2 percent of these sales were made
to customers outside of the service territory of the regulated utility. Revenues
increased  from  $44.7  million in the  quarter  ended  March 31,  1999 to $63.3
million in the quarter  ended March 31,  2000, a 41.5  percent  increase.  These
improvements  were  due  primarily  to the  continuing  growth  of  WGEServices'
customer  base and an increase in the  proportion of customers who are billed on
the basis of their monthly usage, as contrasted with a fixed monthly bill.

         The results produced by the energy marketing segment during the current
quarter  are not  necessarily  representative  of the  results  that  should  be
expected for the entire fiscal year due to seasonal  usage  differences  and the
level of  customer  acquisition  costs  that may be  incurred  as this  business
segment grows. Furthermore,  WGEServices expects to begin selling electricity in
the state of Maryland in the near future, representing another factor that could
increase  expenses  as  customers  are added and  cause the  currently  reported
results to be lower in the near future.


         HVAC

         The HVAC segment designs,  renovates and services  mechanical  heating,
ventilating  and  air  conditioning   systems  for  commercial  and  residential
customers.  Revenues  derived  from the  Company's  commercial  HVAC  activities
increased from $8.8 million in the quarter ended March 31, 1999 to $12.0 million
in the quarter  ended March 31, 2000,  while income from those  operations  rose
from  $340,000 to  $962,000,  respectively.  The  improvement  by the  Company's
commercial HVAC segment resulted from an increase in the number of installations
being undertaken at customers' facilities.

         The  results  for HVAC  also  include  a  $227,000  net  loss  from the
Company's  investment in Primary  Investors,  LLC (Primary),  a residential  and
light commercial HVAC entity in which the

                                        - 21 -


Company acquired a 50 percent interest in August 1999. The Company believes that
the net loss at Primary  results from the incurrence of start-up costs necessary
to integrate companies that are being acquired.  To  date,  seven companies have
been  purchased  by Primary with annualized revenues estimated  at $30  million.
Based on the timing of the acquisitions and the incurrence of integration costs,
Washington Gas  Light anticipates  that it may incur a negligible net  loss from
Primary in fiscal year 2000.

         Customer Financing

         The  customer   financing  segment  provides   financing  for  consumer
purchases of natural gas appliances  and  energy-related  equipment.  Net income
from customer  financing fell $7,000 in the current quarter to $336,000 due to a
lower volume of  contracts  sold by the Company to banks,  combined  with higher
interest rates charged by these banks.

         Sales of Non-Utility Assets

         During  the  quarter  ended  March  31,  2000,  a  non-utility  Company
subsidiary  sold a fully  reserved  preferred  stock  investment  and recorded a
pre-tax  book gain of  $300,000.  In addition,  the same  subsidiary  recorded a
pre-tax  gain of $46,000  from a fully  reserved  venture  fund.  For income tax
purposes,  the sale of the preferred stock investment resulted in a capital loss
transaction for which the Company will realize the tax benefit through a capital
loss  carryback.  In total,  the Company  recorded a $917,000  after-tax gain on
these  transactions,  which  includes  the  tax  benefit  of  the  capital  loss
carryback.

         The  increase in interest on long-term  debt of $333,000 was  primarily
due to a $3.4  million  increase  in the  balance  of  debt  funding  of an HVAC
construction  project for a government agency in Maryland.  The interest expense
relating to this debt is partially  offset by income accrued on the construction
project that is recorded in "Other  Income  (Expenses)--Net."  This  increase in
long-term  debt interest was partially  offset by a $3.5 million  decline in the
average balance of First Mortgage Bonds and Medium-Term Notes (MTNs), as well as
a decrease of 0.16 percentage points in the weighted-average  cost of such debt.
The  embedded  cost of long-term  debt  outstanding  at March 31, 2000,  was 6.8
percent.

         The $1.5 million  increase in interest on short-term  debt was due to a
$95.8  million  rise in the average  short-term  debt balance and an increase of
0.92 percentage  points in the  weighted-average  cost of such debt. The average
balance of short-term debt outstanding  increased during the quarter

                                        - 22 -


ended March 31, 2000, primarily due to: 1) the issuance of common stock and MTNs
early in fiscal year 1999,  of which a  portion  of the  proceeds  were  used to
reduce short-term  debt;  and 2)  increased  short-term  debt  issuances in  the
current quarter due to a higher  volume and cost of storage gas purchases in the
quarter ended March 31, 2000, compared with the same quarter last year.

         Other interest expense  increased  $257,000 due primarily to a decrease
in the accrual for allowance  for funds used during  construction  (AFUDC).  The
decreased  accrual for AFUDC reflects a decline in construction work in progress
due primarily to the completion of the  enterprise-wide  software  system during
the second half of fiscal year 1999, partially offset by the effect of increased
interest  rates during the second quarter of 2000 compared with the same quarter
last year.

         SIX MONTHS ENDED MARCH 31, 2000 VS. MARCH 31, 1999

         EARNINGS
         --------

         For the six months  ended  March 31,  2000,  net income  applicable  to
common stock was $104.4  million,  or $15.3 million  higher than the results for
the same period last year.  Basic and diluted  earnings per average common share
in the current six-month period were $2.25 and $2.24, respectively,  compared to
basic and diluted earnings per share of $1.95 for the same period in fiscal year
1999.  Results for the six months ended March 31, 2000,  included a nonrecurring
gain of $0.02  per  average  common  share  associated  with the  sales of minor
non-utility  investments.  Results  for the six  months  ended  March 31,  1999,
included a $2.1 million ($0.05 per average common share)  nonrecurring  net loss
from the  agreement  to sell  the West   Virginia  natural  gas utility  assets.
Additional  shares  outstanding in the current  six-month period caused earnings
per average common share to be $0.04 lower than last year.

         There were 2.9 percent  fewer degree days during the first half of this
fiscal year,  compared  with the same period last year.  However the Company was
able to increase its basic  earnings per average  common share  because of a 2.9
percent increase in its customer base, a 14.8 percent reduction in operation and
maintenance  expenses  and  continued  profitable  growth by its  energy-related
retail activities.

         Net utility revenues increased $1.7 million, or 0.6 percent, reflecting
a 3.5 percent  increase  in firm therm  deliveries  due to 2.9 percent  customer
growth,  partially offset by weather that was 2.9 percent warmer than last year.
In addition,  utility operation and maintenance expenses decreased $15.5 million
or 14.8 percent in the current  six-month period and enhanced earnings per share
by $0.21 over the same period last year. Net utility  revenues and operation and
maintenance  expenses for 1999 include results from a utility  subsidiary's West
Virginia operations that were subsequently sold in July 1999.

         The Company's three major non-utility  operations contributed $0.10 per
average  common share, a $0.06  improvement  over the six months ended March 31,
1999. The increase was primarily attributable to improvements by the unregulated
energy marketing and HVAC segments.

         NET REVENUES

         Net revenues for the six months ended March 31, 2000, increased by $1.7
million  (0.6  percent)  from the same  period  last year to $310.5  million and
caused  earnings  per average  common share to rise by $0.02 over the six months
ended March 31, 1999. As shown in the following table, a 3.3 percent increase in
the number of customers served by the Company's continuing operations, partially
offset by 2.9 percent warmer weather, resulted in a 4.7 percent

                                        - 23 -


increase in firm therm  deliveries by the Company's continuing operations. These
improvements  more  than  offset  the  $3.2  million  of net  revenues  from the
Company's former West Virginia operations  that were included in the results for
the  six months  ended  March  31,  1999.  However, on a per  therm  basis,  net
revenues earned by the Company on  wholesale  gas  deliveries  to the new  owner
of the West  Virginia utility assets are  significantly lower than those  earned
on direct sales and deliveries to the West Virginia customers during fiscal year
1999,  reflecting a  lower cost of  delivering  gas  on a wholesale  basis.  The
lower price per  therm earned on  deliveries to the  wholesale  provider of  the
Company's  former West Virginia  customers  reduced the  Company's  net revenues
by  approximately  $3 million from the six months ended March 31, 1999.

         Gas Delivered to Firm Customers

         During the six months ended March 31, 2000, firm therm  deliveries rose
by 29.9 million  therms or 3.5 percent  over the same  period  last year.  This
increase  primarily reflects a 3.3 percent rise in the

                                        - 24 -


number of  customer  meters from continuing operations,  partially offset by the
absence  of  sales  this  fiscal  period  to   nearly  3,800  customers  of  the
Company's former  West Virginia operations that  were  sold in July  1999.  Firm
therm  deliveries  were  also adversely  affected by  a 2.9 percent  decrease in
heating  degree days from last year.  Weather for the six months ended March 31,
2000,  was 7.3 percent  warmer than normal,  while weather for  the same  period
last year was 5.1 percent warmer than normal.

         The volume of firm  therm  deliveries  from  continuing  operations  to
customers who purchase  "bundled"  service from  Washington Gas Light  decreased
from  728.2  million  therms in the six  months  ended  March 31,  1999 to 652.9
million  therms  during  the  current  six-month  period,  or a decline  of 10.3
percent.  This decrease was more than offset as the volume of firm gas delivered
for others from the  Company's  continuing  operations  rose from 117.2  million
therms to 232.3 million therms, a 98.3 percent increase.


         Gas Delivered to Interruptible Customers

         Deliveries to interruptible customers during the six months ended March
31, 2000,  decreased by 31.2 million therms or 15.2 percent from the same period
last year,  because of decreased demand by interruptible  customers coupled with
the 2.9 percent  decrease in heating  degree days, as well as the absence of 5.8
million therm sales and  deliveries  associated  with the Company's  former West
Virginia  operations which were included in the results for the six months ended
March 31, 1999. As previously described in this report, the effect on net income
of  changes in gas  deliveries  to  interruptible  customers  is minimal  due to
margin-sharing arrangements in each of the Company's jurisdictions.


         Gas Delivered for Electric Generation

         Volumes  delivered  for electric  generation  in the current  six-month
period increased by 23.6 million therms (79.4 percent) over the same period last
year,  primarily due to decreased usage by these customers during the first half
of fiscal year 2000 compared with the same period last year.  Margins  earned on
such deliveries are being shared with firm customers as described  previously in
this report.


         OTHER OPERATING EXPENSES

         During the six months ended March 31, 2000,  operation and  maintenance
expenses  declined  $15.5 million (14.8  percent) from the prior year's  levels.
This reduction improved earnings per average common share by $0.21 over the same
six-month period last year. The results for the six months ended March 31, 1999,
included  $4.1  million of  operation  and  maintenance  expenses  from the West
Virginia  operations  that  were  sold in July  1999.  Other  key  factors  that
contributed to the variance in operation and maintenance  expenses for the first
six months of fiscal year 2000  compared with the same period for the prior year
include:

       o a $5.3 million reduction in pension and postretirement medical and life
         insurance benefits;

       o a $4.0 million decrease in construction and technical support services;

       o a  $4.0  million  reduction  in  advertising, corporate  relations  and
         miscellaneous  customer  service expenses; and

                                        - 25 -



       o a $2.0 million  reduction in  bad  debt  expense   resulting  from  the
         previously discussed improvement to the Company's collection practices.

         These  reductions were partially  offset by a $2.0 million net increase
in labor and benefit  expenses.  This increase  reflects an increase in employee
wages and  incentives,  partially  offset by the 4.1  percent  reduction  in the
number of utility employees.

         The  operation and  maintenance  expenses  incurred  during the current
six-month  period  reflects the absence of some  expenses  that are likely to be
delayed  until  later  in  the  current  fiscal  year.  Although  operation  and
maintenance  expenses  are likely to increase  for the  remainder of the current
fiscal year, the Company  anticipates  that such expenses for all of fiscal year
2000 will be less than the level incurred for all of fiscal year 1999.

         Depreciation and amortization  increased by $3.3 million (11.4 percent)
in the current six-month period because of the Company's increased investment in
property,  plant and  equipment.  Included in this  increase is $2.1  million of
amortization  related  to the  new  enterprise-wide  software  system  that  was
completed in the second half of fiscal year 1999.  The increase in  depreciation
and  amortization  reduced  earnings per average common share for the six months
ended March 31, 2000, by $0.04 per share when compared to last year.

         Utility  income taxes  increased by $5.6  million,  primarily due to an
11.0  percent  increase  in pre-tax  utility  operating  income for the  current
six-month period.  For utility  operations,  the effective income tax rates were
36.9 percent for the first six months of both fiscal 2000 and 1999.


         NON-UTILITY OPERATING RESULTS
         -----------------------------

         During  the six months  ended  March 31,  2000,  the  results  from the
Company's unregulated energy marketing,  HVAC and customer financing activities,
plus the  impact  of  other  incidental  unregulated  activities  increased  net
operating  income  (after  income taxes,  but before  interest  expense) to $6.3
million  compared to net operating income of $2.1 million earned the same period
last year,  an increase of $4.2  million.  Earnings  per  average  common  share
derived from non-utility  activities were $0.13 in the current six-month period,
an  increase  of $0.09 over last year.  The  increase  in  non-utility  earnings
includes  a  nonrecurring  gain  of  $0.02  per  average  common  share  from  a
subsidiary's sales of certain venture funds and a preferred stock interest.  The
following  table  compares  the  financial  results,   after  income  taxes  and
associated  interest  expense,  from  non-utility  activities for the six months
ended March 31, 2000 and 1999.

         Energy Marketing

         WGEServices,   the  Company's  retail  energy   marketing   subsidiary,
continued to expand rapidly as the subsidiary sold 31.8 billion cubic feet (bcf)
of gas in the current  six-month  period,  an increase of 39.5 percent from 22.8
bcf sold in the first six months of year 1999. During the six months ended March
31, 2000 and 1999,  respectively,  23.5  percent and 21.9 percent of these sales
were  made to  customers  outside  of the  service  territory  of the  regulated
utility. Revenues increased from $67.9 million in the six months ended March 31,
1999 to $107.0  million in the six months  ended March 31,  2000, a 57.6 percent
increase.  Improvements  in  revenues  and net income  for the energy  marketing
segment were due primarily to the  continuing  growth of  WGEServices'  customer
base,  higher  natural gas prices and an increase in the proportion of customers
who are billed on the basis of their monthly  usage as  contrasted  with a fixed
monthly bill. In addition,  WGEServices'  net income has improved because of its
ability to take advantage of favorable  conditions in the natural gas market. As
previously  discussed,  the results produced by the energy marketing segment are
not necessarily representative of the results for the entire fiscal year because
of the  seasonal  nature of the  business and  WGEServices'  planned  entry into
Maryland's electric retail market.


         HVAC

         Revenues   derived  from  the  Company's   commercial  HVAC  activities
increased  from $15.7  million in the six months ended March 31, 1999,  to $22.4
million in the six months ended March 31, 2000,  a 42.7  percent  increase.  Net
income from those  operations  rose from  $524,000 to $1.8  million,  reflecting
increased revenues and the absence of start-up costs, which were incurred during
the first six months of fiscal year 1999.

         The results for the HVAC  segment also include a $327,000 net loss from
the Company's  investment in Primary,  reflecting  start-up  costs  necessary to
integrate companies that are being acquired.  To date, seven companies have been
purchased  by Primary with  annualized  revenues  estimated  at $30 million.  As
mentioned previously in this report, the Company anticipates that it may incur a
negligible net loss from Primary in fiscal year 2000.

         Customer Financing

         Net income from customer  financing  decreased $91,000 in the six-month
period due to a lower volume of contracts sold by the Company to banks, combined
with higher interest rates charged by these banks.

         Sale of Non-Utility Assets

         During the six months  ended  March 31,  2000,  a  non-utility  Company
subsidiary  sold a fully  reserved  preferred  stock  investment  and recorded a
pre-tax  book gain of  $300,000.  In addition,  the same  subsidiary  recorded a
pre-tax  gain of $411,000  from fully  reserved  venture  funds.  For income tax
purposes,  the sale of the preferred stock investment resulted in a capital loss
transaction for which the Company will realize the tax benefit through a capital
loss carryback.  In total, the Company  recorded a $1,154,000  after-tax gain on
these  transactions,  which  includes  the  tax  benefit  of  the  capital  loss
carryback.

         INTEREST EXPENSE
         ----------------

         Total  interest  expense  increased by $2.8 million (14.7 percent) from
the same period last year, reflecting the following changes:

         The increase in interest on short-term  debt of $2.4 million was due to
a $72.2 million rise in the average amount of short-term debt outstanding and an
increase of 0.68 percentage  points in the  weighted-average  cost of such debt.
The average  balance of short-term  debt  outstanding  increased  during the six
months ended March 31, 2000,  primarily  due to: 1) the issuance of common stock
and MTNs early in fiscal year 1999, of which a portion of the proceeds were used
to reduce  short-term debt; and 2) increased  short-term debt issuances due to a
higher  volume and cost of storage gas  purchases  in the six months ended March
31, 2000, compared with the same period last year.

         Other interest expense  increased  $385,000 due primarily to a decrease
in the accrual for AFUDC. The decreased  accrual for AFUDC reflects a decline in
construction   work  in  progress  due  primarily  to  the   completion  of  the
enterprise-wide  software  system  during the second  half of fiscal  year 1999,
partially offset by the effect of increased interest rates during the six months
ended March 31, 2000, compared with the same period last year.

LIQUIDITY AND CAPITAL RESOURCES

         SHORT-TERM CASH REQUIREMENTS AND RELATED FINANCING

         The  Company's  business  is highly  weather  sensitive  and  seasonal.
Approximately 75 percent of the Company's therm deliveries (excluding deliveries
for electric  generation)  occur in the first and second fiscal  quarters.  This
weather  sensitivity  causes short-term cash requirements to vary  significantly
during  the year.  Cash  requirements  peak in the fall and winter  months  when
accounts  receivable,  accrued utility revenues and storage gas are at, or near,
their  highest  levels.  After the  winter  heating  season,  these  assets  are
converted  into cash and are  generally  used to liquidate  short-term  debt and
acquire storage gas for the subsequent heating season.

         At March 31, 2000,  the Company had notes  payable  outstanding,  which
consist of bank loans and  commercial  paper,  of $103.9  million as compared to
$113.1  million at  September  30,  1999.  The  decrease in notes  payable  from
September 1999 reflects the seasonality of the Company's cash requirements.


         LONG-TERM CASH REQUIREMENTS AND RELATED FINANCING

       To fund  construction  expenditures and other capital  requirements,  the
Company  draws upon both  internal and external  sources of cash.  The Company's
ability to generate  adequate cash internally  depends upon a number of factors,
including  the  timing and amount of rate  increases  received  and the level of
therm  deliveries.  The Company's  last  significant  base rate increase  became
effective in December 1994. The number of customer meters and the variability of
the  weather  from  normal  levels  significantly  affect  the  level of  therms
delivered.


         CASH FLOW FROM OPERATING ACTIVITIES

         Net cash provided by operating  activities  during the first six months
of fiscal year 2000 was $85.9 million  compared with $140.7  million  during the
same  period  last  year.  The $54.8  million  decline  in cash  from  operating
activities was primarily the result of:


         o higher funds used to support  accounts  receivable,  as a  result  of
           increased  customer  accounts  receivable associated with non-utility
           operations;

         o a decrease in the source of cash reflected in storage gas  primarily,
           as a result of an increase in the volume of gas stored and higher gas
           prices during the current period; and

         o a reduction in the seasonal over-recovery of purchased gas costs  due
           to customers  during the  six months ended  March  31, 2000, compared
           with the same period last year, primarily because a greater number of
           customers  are choosing  to  purchase  natural  gas from  third-party
           suppliers, rather than from the Company. As described previously, The
           Company does not experience any loss of margins when customers choose
           to purchase their gas from a third-party supplier.

         Partially offsetting these uses of cash was a $22.9 million increase in
net income, adjusted for non-cash items.

                                        - 29 -


         CASH FLOW FROM FINANCING ACTIVITIES

         During  the  first  six  months  of fiscal  year  2000,  there  were no
issuances  or  reacquisitions  of common  stock.  For the same period last year,
$55.7 million was raised  through the sale of 2.3 million shares of common stock
and an  additional  $5.5  million was raised from shares of common  stock issued
through  the  Dividend  Reinvestment  and  Common  Stock  Purchase  Plan and the
Employee Savings Plan.

         During the six months  ended March 31,  2000,  the Company  issued $1.7
million of long-term debt related to the funding of construction projects.

         CASH FLOW FROM INVESTING ACTIVITIES

         Capital  expenditures for the first six months of fiscal year 2000 were
$49.7 million,  on a budget of $125.3 million for fiscal year 2000,  compared to
capital  expenditures  of $75.3  million for the first six months of fiscal year
1999.  The decline was primarily  attributable  to a $11.9  million  decrease in
capital  expenditures  associated  with the Company's  enterprise-wide  software
system during the first six months of fiscal year 2000.

         SALES OF ACCOUNTS RECEIVABLE
         ----------------------------

         During the six months  ended March 31,  2000,  the Company  sold,  with
recourse,  $13.6 million of non-utility accounts  receivable,  compared to $15.5
million in the six months ended March 31, 1999.


OTHER FACTORS AFFECTING THE COMPANY

         CORPORATE STRUCTURE

         Changes in the Company corporate structure, including the establishment
of a holding  company,  are  discussed in Note 2 to the  Consolidated  Financial
Statements.

         ELECTRICITY SUPPLY AGREEMENT

         In  Maryland,  beginning  July 1,  2000,  retail  customers  of Potomac
Electric Power Company,  Baltimore Gas and Electric, Potomac Edison and Delmarva
Power and Light will be able to choose their supplier of electricity. Similar to
the gas  industry, customers of these utilities will have the option to continue
purchasing  their  electricity  "bundled" with the associated  distribution  and
transmission service  from their  current utility.  Customers may also choose to
purchase  electricity  from a  third-party  supplier  and to have their  current
electric utility deliver the energy.  Similar customer choice programs are being
considered  for  electric  customers  in the  Virginia  and District of Columbia
jurisdictions.

         The Company, through its energy marketing subsidiary WGEServices, plans
to begin  marketing  electricity to retail  electric  customers in Maryland this
summer and in other regions as electric customer choice programs are introduced.
On April 3, 2000,  WGEServices entered into a master purchase and sale agreement
with Southern  Company Energy  Marketing  L.P.  (Southern),  a wholesale  energy
marketer.  Under  the  agreement,  WGEServices  can  purchase  electric  energy,
capacity and certain  ancillary  services from Southern,  which WGEServices will
resell to retail electric customers in Maryland and in other regions as customer
choice programs are introduced.

         REGULATORY MATTERS

         Regulatory matters that may have an impact on the Company's  operations
are discussed in Note 7 to the Consolidated Financial Statements.

         YEAR 2000

         Washington Gas Light has continued to operate  successfully through the
turn of the century and during other key dates associated with the transition to
the year 2000.  The  Company  continues  to monitor  its  systems  for Year 2000
issues.

         The  following  table  reflects  the  amounts  charged to  expense  and
capitalized for the six months ended March 31, 2000, and the fiscal years ending
September 30, 1999, 1998 and 1997 for business-application  systems remediation,
embedded systems replacement, end-user applications remediation and replacement,
independent   verification   and  validation   costs  and  business   continuity
initiatives.

         The Company does not anticipate  incurring additional Year 2000-related
costs.

         LABOR MATTERS

         On April 6,  2000,  the  approximately  380  members  of the Office and
Professional  Employees  International  Union  Local 2  voted  to  ratify  a new
three-year labor contract with the Company. Key contract provisions include:

        o a lump sum contract  ratification bonus,  which was  paid on April 13,
          2000, of $1,200 per employee, for a total of $456,000;

        o a general wage increase of 1.5 percent, 1 percent and 2 percent in the
          first, second and third years of the contract, respectively;

        o an  increase  in the Company's matching  contribution  for  the 401(K)
          Savings Plan up to 2 percent in the first year and up to 2.25  percent
          in the second and third years;

        o an  income  security plan that  provides  up to 20 weeks  of  pay  for
          employees  who  may  be  affected  by  a  declaration  in  excess   in
          classification;

        o improved medical, vision and disability coverage; and

        o length of service-based performance bonuses for long-term employees.

         Currently,  negotiations  are  underway  with  the  Teamsters  Local 96
(Teamsters)  labor  union for a contract  that  expires on May 31,  2000,  which
covers 725 field employees,  or 40 percent of the Company's  utility  workforce,
excluding  employees of the  Shenandoah  division.  Later this year, the Company
will negotiate a second  contract with the Teamsters,  which covers 26 field and
office  employees,  or 63 percent of the Shenandoah  division  workforce,  which
expires on July 31, 2000.  Negotiations  will also be undertaken later this year

              higher  than  authorized  by the PSC of DC;  and 2) the  return on

              conditions.
