INDEPENDENT AUDITORS' REPORT


To the Trustee and Participants of the System Thrift Plan of Consolidated
  Natural Gas Company and its Participating Subsidiaries for Employees who are
  not Represented by a Recognized Union

We have audited the accompanying statement of net assets available for benefits
of the System Thrift Plan of Consolidated Natural Gas Company and its
Participating Subsidiaries for Employees who are not Represented by a Recognized
Union (the Plan) as of June 30, 2000 and the related statement of changes in net
assets available for benefits for the year ended June 30, 2000. These financial
statements are the responsibility of the Plan's management. Our responsibility
is to express an opinion on these financial statements based on our audit. The
financial statements of the Plan as of June 30, 1999 were audited by other
auditors whose report, dated April 7, 2000 expressed an unqualified opinion on
those statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of June 30, 2000,
and the changes in net assets available for benefits for the year ended June 30,
2000 in conformity with accounting principles generally accepted in the United
States of America.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules listed in the
Table of Contents are presented for the purpose of additional analysis and are
not a required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. These schedules are the responsibility of the Plan's management. Such
schedules have been subjected to the auditing procedures applied in our audit of
the basic 2000 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

SYSTEM THRIFT PLAN OF CONSOLIDATED NATURAL GAS COMPANY
AND ITS PARTICIPATING SUBSIDIARIES FOR EMPLOYEES WHO ARE
NOT REPRESENTED BY A RECOGNIZED UNION
NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------


1.     DESCRIPTION OF PLAN

         The following description of the System Thrift Plan of Consolidated
         Natural Gas Company and its Participating Subsidiaries for Employees
         who are not Represented by a Recognized Union (the Plan) provides only
         general information. Participants should refer to the Plan document for
         a more complete description of the Plan's provisions.

       a.     GENERAL - The Plan is a defined contribution plan. The
              -------
              participants in the plan are eligible employees of Consolidated
              Natural Gas Company (the Company or CNG) and its Participating
              Subsidiaries (the Employers). The Plan is subject to the
              provisions of the Employee Retirement Income Security Act of 1974
              (ERISA).

              Employee and employer contributions are made pursuant to the terms
              of the plan and are held in funds administered by the Trustees
              under two declarations of trust, i.e., the Long-Term Thrift Trust
              and the Short-Term Thrift Trust (the Trusts).

              The Trusts are maintained in accordance with the Plan's provision
              to provide for the custody and investment of employee and employer
              contributions. They are administered by individual trustees (the
              Trustee) who are appointed by and serve at the pleasure of the
              Company for a term of three years. The Trustees are employed by
              and are officers of various subsidiaries of the Company and serve
              without compensation from the Plan or Trusts. Custody of Plan
              assets resides with Mellon Bank, N.A. who also serves as the
              Plan's Trustee.

       b.     CONTRIBUTIONS - Under the Plan, participants may contribute not
              -------------
              less than 2% and not more than 16% (15% for participants with
              thirty or more years of service) of their earnings each pay
              period, in increments of 1%. If the participant elects that his
              employer make pretax contributions on his behalf, such
              contributions cannot exceed 10%, in increments of 1%, of his
              earnings each pay period subject to applicable Internal Revenue
              Code (IRC) limitations.

       c.     PARTICIPANT ACCOUNTS - Each participant's account includes the
              --------------------
              effect of the participant's contributions and withdrawals, as
              applicable, and allocations of the Company's contributions, Plan
              earnings, and administrative expenses. Allocations are based on
              participant earnings or account balances, as defined. Forfeited
              balances of terminated participants' non-vested accounts are used
              to reduce future employer contributions. The benefit to which a
              participant is entitled is the benefit that can be provided from
              the participant's account.

              Retired participants may elect to receive an amount equal to their
              vested Long-Term Thrift Trust account balance either in a lump sum
              or in installments. For terminations other than retirements,
              participants can only receive their vested Long-Term Thrift Trust

                                      -6-

              account balance as a lump sum distribution. Upon termination and
              retirement, participants can only receive their Short-Term Thrift
              Trust account balance as a lump sum distribution.

       d.     PARTICIPANTS - Each employee is eligible to participate in the
              ------------
              Plan on an entirely voluntary basis. Participation by an employee
              becomes effective immediately upon completion and delivery to the
              Employer (or the Company) of an authorization form furnished by
              the Employer.

       e.     VESTING - Participants immediately vest in their contributions and
              -------
              earnings thereon. Participants vest in the Employer's matching
              contribution and related earnings based upon years of continuous
              service and are fully vested after five years of credited service.
              The Employer's matching contribution is based upon the
              participant's contribution rate and length of service.

       f.     INVESTMENT OPTIONS - Upon enrollment in the Plan, a participant
              ------------------
              may direct contributions in any option (except the loan fund) in
              1% increments totaling to 100%. Investment options are valued
              daily. Changes in investment options may be made at any time and
              become effective with the subsequent pay period. Participants can
              make unlimited transfers among existing funds. The Plan provides
              for employee and employer contributions to be invested in the
              following:

    Short-Term Thrift Trust
    -----------------------

              (1) Interest in CNG Master Trust:

                  CNG Short Term Money Market Fund - The Money Market Fund
                  invests primarily in U.S. Treasury Bills, U.S. Treasury Notes,
                  corporate notes, commercial paper, floating rate notes and

                  Dominion Resources, Inc. (Dominion) Stock Fund - All
                  investments are in Dominion common stock or cash equivalent
                  investments for partial shares. The fund became effective as

                  other investment options. Dividends on Company common stock
                  held in the CNG Stock Fund were invested in additional units
                  of the CNG Stock Fund and credited to participants' accounts.
                  The fund ceased operations as of February 1, 2000.

                                      -7-

                  annuity contracts with one or more insurance companies and
                  other short term fixed income securities. Investments under
                  the contracts mature at various intervals. The interest rates,
                  credited daily to participants' accounts, represent a
                  composite of the income earned under the contracts with the
                  insurance companies and the revenue earned from short-term
                  fixed income securities.

                  Diversified Equity Fund - The fund invests primarily in the
                  common stocks of large U.S. companies.

                  mortgage and other asset-backed securities and money market
                  investments.

              (4) Common/Collective Trusts:

                  The Conservative Balanced Fund, The Moderate Balanced Fund and
                  the Growth Balanced Fund - These funds are common/collective
                  trusts and each is designed to accomplish a specific
                  investment objective. As such, each fund has a different
                  diversified mix of stock, bond and short-term fixed income
                  investments.

       g.     PARTICIPANT LOANS - Participants are eligible to secure loans
              -----------------
              against their plan account and repay the amount over a one to
              five-year period. The maximum loan amount is the lesser of:

              .  3 months base pay or

              .  50% of the vested account balance or

              .  $50,000 (reduced by the maximum outstanding loan balance
                 during the prior 12 months).

              Loan transactions are treated as a transfer between the respective
              investment fund and the loan fund. The loans bear fixed interest
              at a rate commensurate with local prevailing rates at the time the
              loan is issued as determined by the Trustees.

                                      -8-
<PAGE>

              Participants make repayments to the Plan on a monthly basis. Loan
              repayments, including interest, are deposited in the participant's
              account and invested in accordance with the participants' then
              current investment elections. Defaults result in a
              reclassification of the remaining loan balances as taxable
              distributions to the participants.

       h.     PAYMENTS OF BENEFITS - Distributions from the Plan are recorded on
              --------------------
              the valuation date when a participant's valid withdrawal request
              is processed by the recordkeeper. On termination of service, a
              participant may elect to receive either a lump sum amount equal to
              the value of the participant's vested interest in his or her
              account, or defer the payment to a future time no later than the
              year in which the participant attains age 70 1/2.

2.     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       a.     VALUATION OF INVESTMENTS:
              ------------------------

              (1) Dominion Stock Fund - Investments in Dominion common stock are
              stated at fair value based on the closing sales price reported on
              the New York Stock Exchange on the last business day of the plan
              year.

              (2) Investment in Consolidated Natural Gas Master Trust - The fair
              value of the Plan's interest in the Master Trust is based on the
              beginning of the year value of the Plan's interest in the Master
              Trust plus actual contributions and allocated investment income
              less actual distributions and allocated administrative expenses.
              Quoted market prices are used to value investments in the Master
              Trust, with the exception of the trust's investment in the Fixed
              Investment Stable Value Fund.

              Investments in the Fixed Investment Stable Value Fund are stated
              at contract value, which approximates market value. Contract value
              represents contributions and income earned in the fund, less
              withdrawals. The fair market value of the contracts approximates
              the contract value.

              The CNG Stock Fund was stated at market value. Company common
              stock was purchased for participants on the open market, directly
              from the Company, and in certain circumstances, as shares or
              fractional shares from terminating employees' Plan and Employee
              Stock Ownership Plan accounts and other stockholders. Such shares
              or fractional shares were allocated among the accounts of
              participants directing the Trustees to purchase Company common
              stock.

              (3) Mutual Funds - Investments in mutual funds are valued at
              quoted market prices, which represent the net asset values of
              shares held by the Plan at year-end.

              (4) Common/Collective Trusts - Investments in common/collective
              trust funds (funds) are stated at estimated fair values, which
              have been determined based on the unit values of the funds. Unit
              values are determined by the bank (or trust company) sponsoring
              such funds by dividing the fund's net assets by its units
              outstanding at the valuation dates.

                                      -9-
<PAGE>

       b.     INVESTMENT INCOME - Dividend income is recognized on the
              -----------------
              ex-dividend date. Dividends received on all shares of company
              stock are reinvested in additional shares of Dominion common stock
              (previously in shares of CNG common stock).

              Diversified Equity Fund units of the Long-Term Thrift Trust are
              prorated to participants based on the unit value calculated at the
              end of each day.

              Realized gains and losses on the sale of investments are
              determined using the average cost method.

              Net investment income from mutual fund holdings includes dividend
              income and realized and unrealized appreciation/depreciation.

       c.     EXPENSES - The Plan's expenses are accrued as incurred and paid
              --------
              by the Plan, as provided by the Plan document.

       d.     USE OF ESTIMATES - The preparation of financial statements in
              ----------------
              conformity with accounting principles generally accepted in the
              United States of America, requires management to make estimates
              and assumptions that affect the reported amounts of net assets
              available for benefits, and changes therein. Actual results could
              differ from those estimates.

       e.     RECLASSIFICATIONS - The Plan has adopted SOP 99-3 "Accounting and
              -----------------
              Reporting of Certain Defined Contribution Benefit Plan Investments
              and Other Disclosure Matters". As a result, reclassifications have
              been made to eliminate the by-fund disclosure as previously
              required.

       f.     CONCENTRATION OF INVESTMENTS - Included in the Plan's net assets
              ----------------------------
              available for benefits at June 30, 2000, are investments in
              Dominion common stock amounting to approximately $101 million
              whose value could be subject to change based upon market
              conditions.

3.     INVESTMENTS

       The following presents investments that represent 5% or more of the
       Plan's net assets available for benefits:

    During July 1, 1999 through June 30, 2000, the Plan's investments (including
    gains and losses

                                     -10-

                              ===========

4.   PLAN TERMINATION

         Although it has not expressed any intention to do so, the Company has
         the right under the Plan to discontinue its contributions at any time
         and to terminate the Plan subject to the provisions set forth in ERISA.
         In the event of any termination of the Plan, or upon complete or
         partial discontinuance of contributions, the accounts of each affected
         participant shall become fully vested.

5.   PLAN INTEREST IN CONSOLIDATED NATURAL GAS MASTER TRUST

         A portion of the Plan's investments are in a Master Trust which was
         established for the investment of assets of the Plan and the thrift
         plans of other subsidiaries of the Company. The assets of the Master
         Trust are held by Mellon Bank, N.A., as Trustee of the fund. Each
         participating thrift plan has an undivided interest in the Master
         Trust. The assets and income, including net appreciation (depreciation)
         in fair value of plan assets, are allocated to the participating plans
         based on each plan's proportionate share of the units of participation
         held in the fund each month. As of June 30, 2000 and 1999, the Plan's
         interest in the net assets of the Master Trust was approximately 55%
         and 72%, respectively, with varying interests in each of the funds.

         The following table presents the value of the undivided investments
         (and related investment income) in the Master Trust.

       a)    The Fixed Investment Stable Value Fund holds investments in an
           interest bearing cash fund and in fully benefit-responsive insurance
           investment contracts and separate investment accounts. Insurance
           contracts and accounts are included in the financial statements at
           contract value as reported by the various insurance companies.
           Contract value represents contributions made under the contract, plus
           earnings, less participant withdrawals and administrative expenses.
           Participants may ordinarily direct the withdrawal or transfer of all
           or a portion of their investment in this fund at contract value.

           There are no reserves against contract values for credit risks of the
           contract issuers or otherwise. The average yield and crediting
           interest rates for the years ended June 30, 2000 and 1999 were
           approximately 6.55% and 6.5%, respectively.

       b)  The CNG Stock Fund was replaced by the Dominion Stock Fund on
           February 1, 2000. The Dominion Stock Fund is not a part of the CNG
           Master Trust.

6.   TAX STATUS

       The Plan is a qualified employees' profit sharing trust under Sections
       401(a) and 401(k) of the IRC and, as such, is exempt from federal income
       taxes under Section 501(a). Pursuant to Section 402(a) of the IRC, a
       participant is not taxed on the income and pretax contributions allocated
       to the participant's account until such time as the participant or the
       participant's beneficiaries receive distributions from the Plan.

       The Plan obtained its latest determination letter on May 9, 1996, in
       which the Internal Revenue Service stated that the Plan, as amended
       through July 2, 1995, was in compliance with the applicable requirements
       of the Internal Revenue Code. The Plan has been amended since receiving
       the determination letter. However, the Plan administrator and the Plan's
       tax counsel believe that the Plan is currently designed and is currently
       operating in compliance with the applicable requirements of the Internal
       Revenue Code.

7.   MERGER OF CNG AND DOMINION

       On February 12, 1999, CNG and Dominion announced that a definitive merger
       agreement was approved by the Boards of Directors of both companies. On
       May 11, 1999, CNG announced that its Board had unanimously approved an
       amended and restated Agreement and Plan of Merger. The shareholders of
       both the CNG and Dominion and all applicable state regulatory commissions
       and federal regulatory agencies approved the merger.

       The merger agreement called for a two-step merger process. The first
       step, the First Merger, allowed shareholders of Dominion common stock to
       elect to exchange their shares for cash, new Dominion shares or a
       combination of cash and shares. The second step, the Second Merger,
       allowed shareholders of CNG common stock to elect to exchange their old
       shares for cash or new Dominion shares (at a prescribed formula) or a
       combination of cash and shares.

       As directed by the Trustee, Mellon Bank solicited elections from
       participants with respect to shares of stock allocated to their accounts.
       Effective with the completion of the merger, units of participation in
       the CNG Stock Fund were converted to cash and shares of Dominion common
       stock based upon participants' elections (subject to the terms of the
       merger agreement). The fund was renamed the Dominion Stock Fund.

       The merger was finalized on January 28, 2000 and results were posted to
       participants' accounts on February 14, 2000.

INDEPENDENT AUDITORS' REPORT


To the Trustee and Participants of the Thrift Plan of CNG Transmission
  Corporation and Hope Gas Inc. for Employees Represented by the United Gas
  Workers Union, Local 69 - Division II, SEIU, AFL-CIO.

We have audited the accompanying statement of net assets available for benefits
of the Thrift Plan of CNG Transmission Corporation and Hope Gas Inc. for
Employees Represented by the United Gas Workers Union, Local 69 - Division II,
SEIU, AFL-CIO (the Plan) as of June 30, 2000 and the related statement of
changes in net assets available for benefits for the year ended June 30, 2000.
These financial statements are the responsibility of the Plan's management. Our
responsibility is to express an opinion on these financial statements based on
our audit. The financial statements of the Plan as of June 30, 1999 were audited
by other auditors whose report, dated April 7, 2000 expressed an unqualified
opinion on those statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of June 30, 2000,
and the changes in net assets available for benefits for the year ended June 30,
2000 in conformity with accounting principles generally accepted in the United
States of America.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules listed in the
Table of Contents are presented for the purpose of additional analysis and are
not a required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. These schedules are the responsibility of the Plan's management. Such
schedules have been subjected to the auditing procedures applied in our audit of
the basic 2000 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

THRIFT PLAN OF CNG TRANSMISSION CORPORATION AND
HOPE GAS, INC. FOR EMPLOYEES REPRESENTED BY THE UNITED
GAS WORKERS UNION, LOCAL NO. 69 - DIVISION II, SEIU, AFL-CIO


NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

1.  DESCRIPTION OF PLAN

         The following description of the Thrift Plan of CNG Transmission
         Corporation and Hope Gas, Inc. for Employees Represented by the United
         Gas Workers Union, Local Number 69- Division II, SEIU, AFL-CIO.
         Participants should refer to the Plan document for a more complete
         description of the Plan's provisions.

         (a) GENERAL - The Plan is a defined contribution plan. The participants
             -------
         in the plan are union eligible employees of CNG Transmission
         Corporation and Hope Gas, Inc. (the Employers) which are wholly owned
         subsidiaries of Consolidated Natural Gas Company (the Company or CNG).
         The Plan is subject to the provisions of the Employee Retirement Income
         Security Act of 1974 (ERISA).

         Employee and employer contributions are made pursuant to the terms of
         the plan and are held in funds administered by the Trustees under two
         declarations of trust, i.e., the Long-Term Thrift Trust and the
         Short-Term Thrift Trust (the Trusts).

         The Trusts are maintained in accordance with the Plan's provision to
         provide for the custody and investment of employee and employer
         contributions. They are administered by individual trustees (the
         "Trustee") who are appointed by and serve at the pleasure of the
         Company for a term of three years. The Trustees are employed by and are
         officers of various subsidiaries of the Company and serve without
         compensation from the Plan or Trusts. Custody of Plan assets resides
         with Mellon Bank, N.A. who also serves as the Plan's Trustee.

         (b) CONTRIBUTIONS - Under the Plan, participants may contribute not
             -------------
         less than 2% and not more than 16% (15% for participants with thirty or
         more years of service) of their earnings each pay period, in increments
         of 1%. If the participant elects that his employer make pretax
         contributions on his behalf, such contributions cannot exceed 10%, in
         increments of 1%, of his earnings each pay period subject to applicable
         Internal Revenue Code (IRC) limitations.

         (c) PARTICIPANT ACCOUNTS - Each participant's account includes the
             --------------------
         effect of the participant's contributions and withdrawals, as
         applicable, and allocations of the Company's contributions, Plan
         earnings, and administrative expenses. Allocations are based on
         participant earnings or account balances, as defined. Forfeited
         balances of terminated participants' non-vested accounts are used to
         reduce future employer contributions. The benefit to which a
         participant is entitled is the benefit that can be provided from the
         participant's account.

         Retired participants may elect to receive an amount equal to their
         vested Long-Term Thrift Trust account balance either in a lump sum or
         in installments. For terminations other than retirements, participants
         can only receive their vested Long-Term Thrift Trust account balance as
         a lump sum distribution. Upon termination and retirement, participants
         can only receive their Short-Term Thrift Trust account balance as a
         lump sum distribution.

         (d) PARTICIPANTS - Each employee is eligible to participate in the Plan
             ------------
         on an entirely voluntary

                                       6
<PAGE>

         basis. Participation by an employee becomes effective immediately upon
         completion and delivery to the Employer (or the Company) of an
         authorization form furnished by the Employer.

         (e) VESTING - Participants immediately vest in their contributions and
             -------
         earnings thereon. Participants vest in the Employer's matching
         contribution and related earnings based upon years of continuous
         service and are fully vested after five years of credited service. The
         Employer's matching contribution is based upon the participant's
         contribution rate and length of service.

         (f) INVESTMENT OPTIONS - Upon enrollment in the Plan, a participant may
             ------------------
         direct contributions in any option (except the loan fund) in 1%
         increments totaling to 100%. Investment options are valued daily.
         Changes in investment options may be made at any time and become
         effective with the subsequent pay period. Participants can make
         unlimited transfers among existing funds. The Plan provides for
         employee and employer contributions to be invested in the following:

         Short-Term Thrift Trust
         -----------------------

           (1)   Interest in CNG Master Trust:


                 CNG Short Term Money Market Fund - The Money Market Fund
                 invests primarily in U.S. Treasury Bills, U.S. Treasury Notes,
                 corporate notes, commercial paper, floating rate notes and
                 repurchase agreements.

         Long-Term Thrift Trust
         ----------------------

           (1)   Common Stock:


                 Dominion Resources, Inc. (Dominion) Stock Fund - All
                 investments are in Dominion common stock or cash equivalent
                 investments for partial shares. The fund became effective as of
                 February 1, 2000.

           (2)   Interest in CNG Master Trust:


                 CNG Stock Fund - The fund invested primarily in shares of CNG
                 common stock. Participants purchased units of participation in
                 the CNG Stock Fund continuously or from funds transferred from
                 other investment options. Dividends on Company common stock
                 held in the CNG Stock Fund were invested in additional units of
                 the CNG Stock Fund and credited to participants' accounts. The
                 fund ceased operations as of February 1, 2000.

                 Fixed Investment Stable Value Fund - The fund invests in group
                 annuity contracts with one or more insurance companies and
                 other short term fixed income securities. Investments under the
                 contracts mature at various intervals. The interest rates,
                 credited daily to participants' accounts, represent a composite
                 of the income earned under the contracts with the insurance
                 companies and the revenue earned from short-term fixed income
                 securities.

                 companies outside the U.S.

                 The Intermediate Bond Fund - The fund invests primarily in
                 fixed income securities of various maturities such as
                 obligations of the U.S. Government, corporate debt securities,
                 mortgage and other asset-backed securities and money market
                 investments.

           (4)   Common/Collective Trusts:


                 The Conservative Balanced Fund, The Moderate Balanced Fund and
                 the Growth Balanced Fund - These funds are common/collective
                 trusts and each is designed to accomplish a specific investment
                 objective. As such, each fund has a different diversified mix
                 of stock, bond and short-term fixed income investments.

(g) PARTICIPANT LOANS - Participants are eligible to secure loans against their
    -----------------
plan account and repay the amount over a one to five-year period. The maximum
loan amount is the lesser of:

       .  3 months base pay or
       .  50% of the vested account balance or
       .  $50,000 (reduced by the maximum outstanding loan balance during the
          prior 12 months).

Loan transactions are treated as a transfer between the respective investment
fund and the loan fund. The loans bear fixed interest at a rate commensurate
with local prevailing rates at the time the loan is issued as determined by the
Trustees.

Participants make repayments to the Plan on a monthly basis. Loan repayments,
including interest, are deposited in the participant's account and invested in
accordance with the participants then current investment elections. Defaults
result in a reclassification of the remaining loan balances as taxable
distributions to the participants.

(h) PAYMENTS OF BENEFITS - Distributions from the Plan are recorded on the
    --------------------
valuation date when a participant's valid withdrawal request is processed by the
recordkeeper. On termination of service, a participant may elect to receive
either a lump sum amount equal to the value of the participant's vested interest
in his or her account, or defer the payment to a future time no later than the
year in which the participant attains age 70 1/2.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       a.  VALUATION OF INVESTMENTS:
           ------------------------

           (1) Dominion Stock Fund - Investments in Dominion common stock are
           stated at fair value based on the closing sales price reported on the
           New York Stock Exchange on the last business day of the plan year.

           (2) Investment in Consolidated Natural Gas Master Trust - The fair
           value of the Plan's interest in the Master Trust is based on the
           beginning of the year value of the Plan's interest in the Master
           Trust plus actual contributions and allocated investment income less
           actual distributions and allocated administrative expenses. Quoted
           market prices are used to value investments in the Master Trust, with
           the exception of the trust's investment in the Fixed Investment
           Stable Value Fund.

           Investments in the Fixed Investment Stable Value Fund are stated at
           contract value, which approximates market value. Contract value
           represents contributions and income earned in the fund, less
           withdrawals. The fair market value of the contracts approximates the
           contract value.

           The CNG Stock Fund was stated at market value. Company common stock
           was purchased for participants on the open market, directly from the
           Company, and in certain circumstances, as shares or fractional shares
           from terminating employees' Plan and Employee Stock Ownership Plan
           accounts and other stockholders. Such shares or fractional shares
           were allocated among the accounts of participants directing the
           Trustees to purchase Company common stock.

           (3) Mutual Funds - Investments in mutual funds are valued at quoted
           market prices, which represent the net asset values of shares held by
           the Plan at year-end.

           (4) Common/Collective Trusts - Investments in common/collective trust
           funds (funds) are stated at estimated fair values, which have been
           determined based on the unit values of the funds. Unit values are
           determined by the bank (or trust company) sponsoring such funds by
           dividing the fund's net assets by its units outstanding at the
           valuation dates.

         b. INVESTMENT INCOME - Dividend income is recognized on the ex-dividend
         date. Dividends received on all shares of company stock are reinvested
         in additional shares of Dominion common stock (previously in shares of
         CNG common stock).

         Diversified Equity Fund units of the Long-Term Thrift Trust are
         prorated to participants based on the unit value calculated at the end
         of each day.

         Realized gains and losses on the sale of investments are determined
         using the average cost method.

         Net investment income from mutual fund holdings includes dividend
         income and realized and unrealized appreciation/depreciation.

         c. EXPENSES - The Plan's  expenses are accrued as incurred and paid by
            --------
         the Plan, as provided by the Plan document.

         d. USE OF ESTIMATES - The preparation of financial statements in
            ----------------
         conformity with accounting principles generally accepted in the United
         States of America, requires management to make estimates and
         assumptions that affect the reported amounts of net assets available
         for benefits, and

                                       9
<PAGE>

         changes therein. Actual results could differ from those estimates.

         e. RECLASSIFICATIONS - The Plan has adopted SOP 99-3 "Accounting and
            -----------------
         Reporting of Certain Defined Contribution Benefit Plan Investments and
         Other Disclosure Matters". As a result, reclassifications have been
         made to eliminate the by-fund disclosure as previously required.
         f. CONCENTRATION OF INVESTMENTS - Included in the Plan's net assets
            ----------------------------
         available for benefits at June 30, 2000, are investments in Dominion
         common stock amounting to approximately $74 million whose value could
         be subject to change based upon market conditions.

3.  INVESTMENTS

The following presents investments that represent 5% or more of the Plan's net
assets available for benefits:

                                                      June 30,
                                              2000                1999

    CNG Common Stock                               -           101,452,721


    During July 1, 1999 through June 30, 2000, the Plan's investments (including
    gains and losses on investments bought and sold, as well as held during the
    year) appreciated in value by $15,587,490 as follows:

4.  PLAN TERMINATION

      Although it has not expressed any intention to do so, the Company has the
      right under the Plan to discontinue its contributions at any time and to
      terminate the Plan subject to the provisions set forth in ERISA. In the
      event of any termination of the Plan, or upon complete or partial
      discontinuance of contributions, the accounts of each affected participant
      shall become fully vested.

5.  PLAN INTEREST IN CONSOLIDATED NATURAL GAS MASTER TRUST

      A portion of the Plan's investments are in a Master Trust which was
      established for the investment of assets of the Plan and the thrift plans
      of other subsidiaries of the Company. The assets of the Master Trust are
      held by Mellon Bank, N.A., as Trustee of the fund. Each participating
      thrift plan has an undivided interest in the Master Trust. The assets and
      income, including net appreciation (depreciation) in fair value of plan
      assets, are allocated to the participating plans based on each plan's
      proportionate share of the units of participation held in the fund each
      month. As of June 30, 2000 and 1999, the Plan's interest in the net assets
      of the Master Trust was approximately 15% and 1%, respectively, with
      varying interests in each of the funds.

      The following table presents the value of the undivided investments (and
      related investment income) in the Master Trust.

                                                             June 30,

         a) The Fixed Investment Stable Value Fund holds investments in an
         interest bearing cash fund and in fully benefit-responsive insurance
         investment contracts and separate investment accounts. Insurance
         contracts and accounts are included in the financial statement at
         contract value as reported by the various insurance companies. Contract
         value represents contributions made under the contract, plus earnings,
         less participant withdrawals and administrative expenses. Participants
         may ordinarily direct the withdrawal or transfer of all or a portion of
         their investment in this fund at contract value.

         There are no reserves against contract values for credit risks of the
         contract issuers or otherwise. The average yield and crediting interest
         rates for the years ended June 30, 2000 and 1999 were approximately
         6.55% and 6.5%, respectively.

                                       11
<PAGE>

         b)  The CNG Stock Fund was replaced by the Dominion Stock Fund on
             February 1, 2000. The Dominion Stock Fund is not a part of the CNG
             Master Trust.

6.  TAX STATUS

         The Plan is a qualified employees' profit sharing trust under Sections
         401(a) and 401(k) of the IRC and, as such, is exempt from federal
         income taxes under Section 501(a). Pursuant to Section 402(a) of the
         IRC, a participant is not taxed on the income and pretax contributions
         allocated to the participant's account until such time as the
         participant or the participant's beneficiaries receive distributions
         from the Plan.

         The Plan obtained its latest determination letter on November 7, 1995,
         in which the Internal Revenue Service stated that the Plan, as amended
         through December 20, 1994 was in compliance with the applicable
         requirements of the Internal Revenue Code. The Plan has been amended
         since receiving the determination letter. However, the Plan
         administrator and the Plan's tax counsel believe that the Plan is
         currently designed and is currently operating in compliance with the
         applicable requirements of the Internal Revenue Code.

7.  MERGER OF CNG AND DOMINION

         On February 12, 1999, CNG and Dominion announced that a definitive
         merger agreement was approved by the Boards of Directors of both
         companies. On May 11, 1999, CNG announced that its Board had
         unanimously approved an amended and restated Agreement and Plan of
         Merger. The shareholders of both the CNG and Dominion and all
         applicable state regulatory commissions and federal regulatory agencies
         approved the merger.

         The merger agreement called for a two-step merger process. The first
         step, the First Merger, allowed shareholders of Dominion common stock
         to elect to exchange their shares for cash, new Dominion shares or a
         combination of cash and shares. The second step, the Second Merger,
         allowed shareholders of CNG common stock to elect to exchange their old
         shares for cash or new Dominion shares (at a prescribed formula) or a
         combination of cash and shares.

         As directed by the Trustee, Mellon Bank solicited elections from
         participants with respect to shares of stock allocated to their
         accounts. Effective with the completion of the merger, units of
         participation in the CNG Stock Fund were converted to cash and shares
         of Dominion common stock based upon participants' elections (subject to
         the terms of the merger agreement). The fund was renamed the Dominion
         Stock Fund.

         The merger was finalized on January 28, 2000 and results were posted to
         participants' accounts on February 14, 2000.

INDEPENDENT AUDITORS' REPORT

To the Trustee and Participants of the
  Thrift Plan of East Ohio Gas Company for Employees
  Represented by the Natural Gas Workers Union, Local 555, SEIU, AFL-CIO

We have audited the accompanying statement of net assets available for benefits
of the Thrift Plan of East Ohio Gas Company for Employees Represented by the
Natural Gas Workers Union, Local 555, SEIU, AFL-CIO (the Plan) as of June 30,
2000 and the related statement of changes in net assets available for benefits
for the year ended June 30, 2000.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to express an
opinion on these financial statements based on our audit. The financial
statements of the Plan as of June 30, 1999 were audited by other auditors whose
report, dated April 7, 2000 expressed an unqualified opinion on those
statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of June 30, 2000,
and the changes in net assets available for benefits for the year ended June 30,
2000 in conformity with accounting principles generally accepted in the United
States of America.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules listed in the
Table of Contents are presented for the purpose of additional analysis and are
not a required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974.  These schedules are the responsibility of the Plan's management.  Such
schedules have been subjected to the auditing procedures applied in our audit of
the basic 2000 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

THRIFT PLAN OF THE EAST OHIO GAS COMPANY
FOR EMPLOYEES REPRESENTED BY THE NATURAL GAS
WORKERS UNION, LOCAL 555, SEIU, AFL-CIO

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

1.  DESCRIPTION OF PLAN

          The following description of the Thrift Plan of the East Ohio Gas
          Company for Employees Represented by the Natural Gas Workers Union,
          Local 555, SEIU, AFL-CIO (the Plan) provides only general information.
          Participants should refer to the Plan document for a more complete
          description of the Plan's provisions.

          a. GENERAL - The Plan is a defined contribution plan. The participants
             -------
          in the Plan are union- eligible employees of East Ohio Gas Company
          (the Employer). The East Ohio Gas Company is a wholly-owned subsidiary
          of Consolidated Natural Gas Company (the Company or CNG). Each
          employee is eligible to participate in the plan on an entirely
          voluntary basis. Participation by an employee becomes effective
          immediately upon completion and delivery to the employer of an
          authorized form furnished by the employer. The Plan is subject to the
          provisions of the Employee Retirement Income Security Act of 1974
          (ERISA).

          Employee and employer contributions are made pursuant to the terms of
          the plan and are held in funds administered by the Trustees under two
          declarations of trust, i.e., the Long-Term Thrift Trust and the Short-
          Term Thrift Trust (the Trusts).

          The Trusts are maintained in accordance with the Plan's provision to
          provide for the custody and investment of employee and employer
          contributions. They are administered by individual trustees (the
          Trustee) who are appointed by and serve at the pleasure of the Company
          for a term of three years. The Trustees are employed by and are
          officers of various subsidiaries of the Company and serve without
          compensation from the Plan or Trusts. Custody of Plan assets resides
          with Mellon Bank, N.A. who also serves as the Plan's Trustee.

          b. CONTRIBUTIONS - Under the Plan, participants may contribute not
             -------------
          less than 2% and not more than 16% (15% for participants with thirty
          or more years of service) of their earnings each pay period, in
          increments of 1%. If the participant elects that his employer make
          pretax contributions on his behalf, such contributions cannot exceed
          10%, in increments of 1%, of his earnings each pay period subject to
          applicable Internal Revenue Code (IRC) limitations.

          c. PARTICIPANT ACCOUNTS - Each participant's account includes the
             --------------------
          effect of the participant's contributions and withdrawals, as
          applicable, and allocations of the Company's contributions, Plan
          earnings, and administrative expenses. Allocations are based on
          participant earnings or account balances, as defined. Forfeited
          balances of terminated participants' non-vested accounts are used to
          reduce future employer contributions. The benefit to which a
          participant is entitled is the benefit that can be provided from the
          participant's account.

          Retired participants may elect to receive an amount equal to their
          vested Long-Term Thrift Trust account balance either in a lump sum or
          in installments. For terminations other than retirements, participants
          can only receive their vested Long-Term Thrift Trust account balance
          as a lump sum distribution. Upon termination and retirement,
          participants can only receive their Short-Term Thrift

                                       6
<PAGE>

          Trust account balance as a lump sum distribution.

          d. PARTICIPANTS - Each employee is eligible to participate in the Plan
             ------------
          on an entirely voluntary basis. Participation by an employee becomes
          effective immediately upon completion and delivery to the Employer (or
          the Company) of an authorization form furnished by the Employer.

          e. VESTING - Participants immediately vest in their contributions and
             -------
          earnings thereon. Participants vest in the Employer's matching
          contribution and related earnings based upon years of continuous
          service and are fully vested after five years of credited service. The
          Employer's matching contribution is based upon the participant's
          contribution rate and length of service.

          f. INVESTMENT OPTIONS - Upon enrollment in the Plan, a participant may
             ------------------
          direct contributions in any option (except the loan fund) in 1%
          increments totaling to 100%. Investment options are valued daily.
          Changes in investment options may be made at any time and become
          effective with the subsequent pay period. Participants can make
          unlimited transfers among existing funds. The Plan provides for
          employee and employer contributions to be invested in the following:

          Short-Term Thrift Trust
          -----------------------

          (1) Interest in CNG Master Trust:


               CNG Short Term Money Market Fund - The Money Market Fund invests
               primarily in U.S. Treasury Bills, U.S. Treasury Notes, corporate
               notes, commercial paper, floating rate notes and repurchase
               agreements.

          Long-Term Thrift Trust
          ----------------------

          (1) Common Stock:

               Dominion Resources, Inc. (Dominion) Stock Fund - All investments
               are in Dominion common stock or cash equivalent investments for
               partial shares. The fund became effective as of February 1, 2000.

          (2) Interest in CNG Master Trust:

               CNG Stock Fund - The fund invested primarily in shares of CNG
               common stock. Participants purchased units of participation in
               the CNG Stock Fund continuously or from funds transferred from
               other investment options. Dividends on Company common stock held
               in the CNG Stock Fund were invested in additional units of the
               CNG Stock Fund and credited to participants' accounts. The fund
               ceased operations as of February 1, 2000.

               Fixed Investment Stable Value Fund - The fund invests in group
               annuity contracts with one or more insurance companies and other
               short term fixed income securities. Investments under the
               contracts mature at various intervals. The interest rates,
               credited daily to participants' accounts, represent a composite
               of the income earned under the contracts with the insurance
               companies and the revenue earned from short-term fixed income
               securities.

                                       7
<PAGE>

               Diversified Equity Fund - The fund invests primarily in the
               common stocks of large U.S. companies.

               (3)  Mutual Funds:

               The Masterworks S&P 500 Index Fund - The fund invests
               proportionately in all or nearly all of the stocks that are
               included in the Standard & Poor's 500 Stock Index.

               The Small Stock Fund - The fund invests in stocks of small to
               mid-sized U.S. companies.

               The International Equity Fund - The fund invests in stocks of
               companies outside the U.S.

               The Intermediate Bond Fund - The fund invests primarily in fixed
               income securities of various maturities such as obligations of
               the U.S. Government, corporate debt securities, mortgage and
               other asset-backed securities and money market investments.

               (4)  Common/Collective Trusts:

               The Conservative Balanced Fund, The Moderate Balanced Fund and
               the Growth Balanced Fund - These funds are common/collective
               trusts and each is designed to accomplish a specific investment
               objective. As such, each fund has a different diversified mix of
               stock, bond and short-term fixed income investments.

     g.   PARTICIPANT LOANS - Participants are eligible to secure loans against
          -----------------
     their plan account and repay the amount over a one to five-year period. The
     maximum loan amount is the lesser of:

          .  3 months base pay or 50% of the vested account balance or

          .  $50,000 (reduced by the maximum outstanding loan balance during the
             prior 12 months).

          Loan transactions are treated as a transfer between the respective
          investment fund and the loan fund. The loans bear fixed interest at a
          rate commensurate with local prevailing rates at the time the loan is
          issued as determined by the Trustees.

          Participants make repayments to the Plan on a monthly basis. Loan
          repayments, including interest, are deposited in the participant's
          account and invested in accordance with the participants' then current
          investment elections. Defaults result in a reclassification of the
          remaining loan balances as taxable distributions to the participants.

     h.   PAYMENTS OF BENEFITS - Distributions from the Plan are recorded on the
          --------------------
     valuation date when a participant's valid withdrawal request is processed
     by the recordkeeper. On termination of service, a participant may elect to
     receive either a lump sum amount equal to the value of the participant's
     vested interest in his or her account, or defer the payment to a future
     time no later than the year in which the participant attains age 70 1/2.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a.  VALUATION OF INVESTMENTS:
         ------------------------

          (1)  Dominion Stock Fund - Investments in Dominion common stock are
               stated at fair value based on the closing sales price reported on
               the New York Stock Exchange on the last business day of the plan
               year.

          (2)  Investment in Consolidated Natural Gas Master Trust - The fair
               value of the Plan's interest in the Master Trust is based on the
               beginning of the year value of the Plan's interest in the Master
               Trust plus actual contributions and allocated investment income
               less actual distributions and allocated administrative expenses.
               Quoted market prices are used to value investments in the Master
               Trust, with the exception of the trust's investment in the Fixed
               Investment Stable Value Fund.

               Investments in the Fixed Investment Stable Value Fund are stated
               at contract value, which approximates market value. Contract
               value represents contributions and income earned in the fund,
               less withdrawals. The fair market value of the contracts
               approximates the contract value.

               The CNG Stock Fund was stated at market value. Company common
               stock was purchased for participants on the open market, directly
               from the Company, and in certain circumstances, as shares or
               fractional shares from terminating employees' Plan and Employee
               Stock Ownership Plan accounts and other stockholders. Such shares
               or fractional shares were allocated among the accounts of
               participants directing the Trustees to purchase Company common
               stock.

          (3)  Mutual Funds - Investments in mutual funds are valued at quoted
               market prices, which represent the net asset values of shares
               held by the Plan at year-end.

          (4)  Common/Collective Trusts - Investments in common/collective trust
               funds (funds) are stated at estimated fair values, which have
               been determined based on the unit values of the funds. Unit
               values are determined by the bank (or trust company) sponsoring
               such funds by dividing the fund's net assets by its units
               outstanding at the valuation dates.

          b.   INVESTMENT INCOME - Dividend income is recognized on the ex-
               -----------------
          dividend date. Dividends received on all shares of company stock are
          reinvested in additional shares of Dominion common stock (previously
          in shares of CNG common stock).

          Diversified Equity Fund units of the Long-Term Thrift Trust are
          prorated to participants based on the unit value calculated at the end
          of each day.

          Realized gains and losses on the sale of investments are determined
          using the average cost method.

          Net investment income from mutual fund holdings includes dividend
          income and realized and unrealized appreciation/depreciation.

          c.   EXPENSES - The Plan's expenses are accrued as incurred and paid
               --------
          by the Plan, as provided by the Plan document.

          d.   USE OF ESTIMATES - The preparation of financial statements in
               ----------------
          conformity with accounting principles generally accepted in the United
          States of America, requires management to make estimates and
          assumptions that affect the reported amounts of net assets available
          for benefits, and changes therein. Actual results could differ from
          those estimates.

          e.   RECLASSIFICATIONS - The Plan has adopted SOP 99-3 "Accounting and
               -----------------
          Reporting of Certain Defined Contribution Benefit Plan Investments and
          Other Disclosure Matters". As a result, reclassifications have been
          made to eliminate the by-fund disclosure as previously required.

          f.   CONCENTRATION OF INVESTMENTS - Included in the Plan's net assets
               ----------------------------
          available for benefits at June 30, 2000, are investments in Dominion
          common stock amounting to approximately $55 million whose value could
          be subject to change based upon market conditions.

3. INVESTMENTS

     The following presents investments that represent 5% or more of the Plan's
           net assets available for benefits:

                                                          June 30,

     During July 1, 1999 through June 30, 2000, the Plan's investments
          (including gains and losses on investments bought and sold, as well as
          held during the year) appreciated in value by $16,115,208 as follows:

4. PLAN TERMINATION

     Although it has not expressed any intention to do so, the Company has the
     right under the Plan to discontinue its contributions at any time and to
     terminate the Plan subject to the provisions set forth in ERISA.  In the
     event of any termination of the Plan, or upon complete or partial
     discontinuance of contributions, the accounts of each affected participant
     shall become fully vested.

5. PLAN INTEREST IN CONSOLIDATED NATURAL GAS MASTER TRUST

     A portion of the Plan's investments are in a Master Trust which was
     established for the investment of assets of the Plan and the thrift plans
     of other subsidiaries of the Company.  The assets of the Master Trust are
     held by Mellon Bank, N.A., as Trustee of the fund. Each participating
     thrift plan has an undivided interest in the Master Trust.  The assets and
     income, including net appreciation (depreciation) in fair value of plan
     assets, are allocated to the participating plans based on each plan's
     proportionate share of the units of participation held in the fund each
     month.  As of June 30, 2000 and 1999, the Plan's interest in the net assets
     of the Master Trust was approximately 19% and 27%, respectively, with
     varying interests in each of the funds.

     The following table presents the value of the undivided investments (and
          related investment income) in the Master Trust.

                                                               June 30,

                                                   ============    ============


     (a) The Fixed Investment Stable Value Fund holds investments in an interest
         bearing cash fund and in fully benefit-responsive insurance investment
         contracts and separate investment accounts. Insurance contracts and
         accounts are included in the financial statement at contract value as
         reported by the various insurance companies. Contract value represents
         contributions made under the contract, plus earnings, less participant
         withdrawals and administrative expenses. Participants may ordinarily
         direct the withdrawal or transfer of all or a portion of their
         investment in this fund at contract value.

         There are no reserves against contract values for credit risks of the
         contract issuers or otherwise. The average yield and crediting interest
         rates for the years ended June 30, 2000 and 1999 were approximately
         6.55% and 6.5%, respectively.

     (b) The CNG Stock Fund was replaced by the Dominion Stock Fund on February
         1, 2000.  The Dominion Stock Fund is not a part of the CNG Master
         Trust.

6. TAX STATUS

     The Plan is a qualified employees' profit sharing trust under Sections
     401(a) and 401(k) of the IRC and, as such, is exempt from federal income
     taxes under Section 501(a).  Pursuant to Section 402(a) of the IRC, a
     participant is not taxed on the income and pretax contributions allocated
     to the participant's account until such time as the participant or the
     participant's beneficiaries receive distributions from the Plan.

     The Plan obtained its latest determination letter on November 1, 1995, in
     which the Internal Revenue Service stated that the Plan, as amended through
     December 22, 1994 was in compliance with the applicable requirements of the
     Internal Revenue Code.  The Plan has been amended since receiving the
     determination letter.  However, the Plan administrator and the Plan's tax
     counsel believe that the Plan is currently designed and is currently
     operating in compliance with the applicable requirements of the Internal
     Revenue Code.

7. MERGER OF CNG AND DOMINION

     On February 12, 1999, CNG and Dominion announced that a definitive merger
     agreement was approved by the Boards of Directors of both companies.  On
     May 11, 1999, CNG announced that its Board had unanimously approved an
     amended and restated Agreement and Plan of Merger.  The shareholders of
     both the CNG and Dominion and all applicable state regulatory commissions
     and federal regulatory agencies approved the merger.

     The merger agreement called for a two-step merger process.  The first step,
     the First Merger, allowed shareholders of Dominion common stock to elect to
     exchange their shares for cash, new Dominion shares or a combination of
     cash and shares.  The second step, the Second Merger, allowed shareholders
     of CNG common stock to elect to exchange their old shares for cash or new
     Dominion shares (at a prescribed formula) or a combination of cash and
     shares.

     As directed by the Trustee, Mellon Bank solicited elections from
     participants with respect to shares of stock allocated to their accounts.
     Effective with the completion of the merger, units of participation in the
     CNG Stock Fund were converted to cash and shares of Dominion common stock
     based upon participants' elections (subject to the terms of the merger
     agreement).  The fund was renamed the Dominion Stock Fund.

     The merger was finalized on January 28, 2000 and results were posted to
     participants' accounts on February 14, 2000.

INDEPENDENT AUDITORS' REPORT

To the Trustee and Participants of the
  Thrift Plan of East Ohio Gas Company for Employees
  Represented by the Natural Gas Workers Union, Local 555, SEIU, AFL-CIO

We have audited the accompanying statement of net assets available for benefits
of the Thrift Plan of East Ohio Gas Company for Employees Represented by the
Natural Gas Workers Union, Local 555, SEIU, AFL-CIO (the Plan) as of June 30,
2000 and the related statement of changes in net assets available for benefits
for the year ended June 30, 2000.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to express an
opinion on these financial statements based on our audit. The financial
statements of the Plan as of June 30, 1999 were audited by other auditors whose
report, dated April 7, 2000 expressed an unqualified opinion on those
statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of June 30, 2000,
and the changes in net assets available for benefits for the year ended June 30,
2000 in conformity with accounting principles generally accepted in the United
States of America.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules listed in the
Table of Contents are presented for the purpose of additional analysis and are
not a required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974.  These schedules are the responsibility of the Plan's management.  Such
schedules have been subjected to the auditing procedures applied in our audit of
the basic 2000 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

THRIFT PLAN OF THE PEOPLES NATURAL GAS COMPANY
FOR EMPLOYEES REPRESENTED BY UNITED GAS WORKERS UNION,
LOCAL 69 - DIVISION I, SEIU, AFL-CIO

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

1. DESCRIPTION OF PLAN

     The following description of the Thrift Plan of the Peoples Natural Gas
     Company (CNG) for Employees Represented by the United Gas Workers Union,
     Local No. 69 - Division 1, SEIU, AFL-CIO (the Plan) provides only general
     information.  Participants should refer to the Plan document for a more
     complete description of the Plan's provisions.

      a.  GENERAL - The Plan is a defined contribution plan.  The participants
          -------
      in the plan are union-eligible employees of Peoples Natural Gas Company
      (the Employer).  The Employer is a wholly-owned subsidiary of Consolidated
      Natural Gas Company (the Company or CNG).  Each employee is eligible to
      participate in the Plan on a voluntary basis.  Participation by an
      employee becomes effective immediately upon completion and delivery to the
      employer of an authorized form furnished by the employer.  The Plan is
      subject to the provisions of the Employee Retirement Income Security Act
      of 1974 (ERISA).

      Employee and employer contributions are made pursuant to the terms of the
      plan and are held in funds administered by the Trustees under two
      declarations of trust, i.e., the Long-Term Thrift Trust and the Short-Term
      Thrift Trust (the "Trusts").

      The Trusts are maintained in accordance with the Plan's provision to
      provide for the custody and investment of employee and employer
      contributions.  They are administered by individual trustees (the
      "Trustee") who are appointed by and serve at the pleasure of the Company
      for a term of three years.  The Trustees are employed by and are officers
      of various subsidiaries of the Company and serve without compensation from
      the Plan or Trusts.  Custody of Plan assets resides with Mellon Bank, N.A.
      who also serves as the Plan's Trustee.

      b.  CONTRIBUTIONS - Under the Plan, participants may contribute not less
          -------------
      than 2% and not more than 16% (15% for participants with thirty or more
      years of service) of their earnings each pay period, in increments of 1%.
      If the participant elects that his employer make pretax contributions on
      his behalf, such contributions cannot exceed 10%, in increments of 1%, of
      his earnings each pay period subject to applicable Internal Revenue Code
      (IRC) limitations.

      c. PARTICIPANT ACCOUNTS - Each participant's account includes the effect
         --------------------
      of the participant's contributions and withdrawals, as applicable, and
      allocations of the Company's contributions, Plan earnings, and
      administrative expenses.  Allocations are based on participant earnings or
      account balances, as defined.  Forfeited balances of terminated
      participants' non-vested accounts are used to reduce future employer
      contributions.  The benefit to which a participant is entitled is the
      benefit that can be provided from the participant's account.

      Retired participants may elect to receive an amount equal to their vested
      Long-Term Thrift Trust account balance either in a lump sum or in
      installments.  For terminations other than retirements, participants can
      only receive their vested Long-Term Thrift Trust account balance as a lump
      sum distribution.  Upon termination and retirement, participants can only
      receive their Short-Term Thrift

                                       6
<PAGE>

      Trust account balance as a lump sum distribution.

      d.  PARTICIPANTS - Each employee is eligible to participate in the Plan on
          ------------
      an entirely voluntary basis.  Participation by an employee becomes
      effective immediately upon completion and delivery to the Employer (or the
      Company) of an authorization form furnished by the Employer.

      e.  VESTING - Participants immediately vest in their contributions and
          -------
      earnings thereon.  Participants vest in the Employer's matching
      contribution and related earnings based upon years of continuous service
      and are fully vested after five years of credited service.  The Employer's
      matching contribution is based upon the participant's contribution rate
      and length of service.

      f.  INVESTMENT OPTIONS - Upon enrollment in the Plan, a participant may
          ------------------
      direct contributions in any option (except the loan fund) in 1% increments
      totaling to 100%.  Investment options are valued daily.  Changes in
      investment options may be made at any time and become effective with the
      subsequent pay period.  Participants can make unlimited transfers among
      existing funds.  The Plan provides for employee and employer contributions
      to be invested in the following:

     Short-Term Thrift Trust
     -----------------------

      (1) Interest in CNG Master Trust:

            CNG Short Term Money Market Fund - The Money Market Fund invests
            primarily in U.S. Treasury Bills, U.S. Treasury Notes, corporate
            notes, commercial paper, floating rate notes and repurchase
            agreements.

     Long-Term Thrift Trust
     ----------------------

      (1) Common Stock:

            Dominion Resources, Inc. (Dominion) Stock Fund - All investments are
            in Dominion common stock or cash equivalent investments for partial
            shares. The fund became effective as of February 1, 2000.

      (2) Interest in CNG Master Trust:

            CNG Stock Fund - The fund invested primarily in shares of CNG common
            stock. Participants purchased units of participation in the CNG
            Stock Fund continuously or from funds transferred from other
            investment options. Dividends on Company common stock held in the
            CNG Stock Fund were invested in additional units of the CNG Stock
            Fund and credited to participants' accounts. The fund ceased
            operations as of February 1, 2000.

            Fixed Investment Stable Value Fund - The fund invests in group
            annuity contracts with one or more insurance companies and other
            short term fixed income securities. Investments under the contracts
            mature at various intervals. The interest rates, credited daily to
            participants' accounts, represent a composite of the income earned
            under the contracts with the insurance companies and the revenue
            earned from short-term fixed income securities.

                                       7
<PAGE>

          Diversified Equity Fund - The fund invests primarily in the common
          stocks of large U.S. companies.

     (3) Mutual Funds:

          The Masterworks S&P 500 Index Fund - The fund invests proportionately
          in all or nearly all of the stocks that are included in the Standard &
          Poor's 500 Stock Index.

          The Small Stock Fund - The fund invests in stocks of small to mid-
          sized U.S. companies.

          The International Equity Fund - The fund invests in stocks of
          companies outside the U.S.

          The Intermediate Bond Fund - The fund invests primarily in fixed
          income securities of various maturities such as obligations of the
          U.S. Government, corporate debt securities, mortgage and other asset-
          backed securities and money market investments.

     (4) Common/Collective Trusts:

          The Conservative Balanced Fund, The Moderate Balanced Fund and The
          Growth Balanced Fund - These funds are common/collective trusts and
          each is designed to accomplish a specific investment objective. As
          such, each fund has a different diversified mix of stock, bond and
          short-term fixed income investments.

     g.  PARTICIPANT LOANS - Participants are eligible to secure loans against
         -----------------
      their plan account and repay the amount over a one to five-year period.
      The maximum loan amount is the lesser of;

     .  3 months base pay or
     .  50% of the vested account balance or
     .  $50,000 (reduced by the maximum outstanding loan balance during the
        prior 12 months).

     Loan transactions are treated as a transfer between the respective
     investment fund and the loan fund. The loans bear fixed interest at a rate
     commensurate with local prevailing rates at the time the loan is issued as
     determined by the Trustees.

     Participants make repayments to the Plan on a monthly basis. Loan
     repayments, including interest, are deposited in the participant's account
     and invested in accordance with the participants then current investment
     elections. Defaults result in a reclassification of the remaining loan
     balances as taxable distributions to the participants.

     h.  PAYMENTS OF BENEFITS - Distributions from the Plan are recorded on the
          ---------------------
     valuation date when a participant's valid withdrawal request is processed
     by the recordkeeper. On termination of service, a participant may elect to
     receive either a lump sum amount equal to the value of the participant's
     vested interest in his or her account, or defer the payment to a future
     time no later than the year in which the participant attains age 70 1/2.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     a.  VALUATION OF INVESTMENTS:
         ------------------------

          (1) Dominion Stock Fund - Investments in Dominion common stock are
          stated at fair value based on the closing sales price reported on the
          New York Stock Exchange on the last business day of the plan year.

          (2) Investment in Consolidated Natural Gas Master Trust - The fair
          value of the Plan's interest in the Master Trust is based on the
          beginning of the year value of the Plan's interest in the Master Trust
          plus actual contributions and allocated investment income less actual
          distributions and allocated administrative expenses. Quoted market
          prices are used to value investments in the Master Trust, with the
          exception of the trust's investment in the Fixed Investment Stable
          Value Fund.

          Investments in the Fixed Investment Stable Value Fund are stated at
          contract value, which approximates market value. Contract value
          represents contributions and income earned in the fund, less
          withdrawals. The fair market value of the contracts approximates the
          contract value.

          The CNG Stock Fund was stated at market value. Company common stock
          was purchased for participants on the open market, directly from the
          Company, and in certain circumstances, as shares or fractional shares
          from terminating employees' Plan and Employee Stock Ownership Plan
          accounts and other stockholders. Such shares or fractional shares were
          allocated among the accounts of participants directing the Trustees to
          purchase Company common stock.

          (3) Mutual Funds - Investments in mutual funds are valued at quoted
          market prices, which represent the net asset values of shares held by
          the Plan at year-end.

          (4) Common/Collective Trusts - Investments in common/collective trust
          funds (funds) are stated at estimated fair values, which have been
          determined based on the unit values of the funds. Unit values are
          determined by the bank (or trust company) sponsoring such funds by
          dividing the fund's net assets by its units outstanding at the
          valuation dates.

     b.  INVESTMENT INCOME - Dividend income is recognized on the ex-dividend
         -----------------
     date. Dividends received on all shares of company stock are reinvested in
     additional shares of Dominion common stock (previously in shares of CNG
     common stock).

     Diversified Equity Fund units of the Long-Term Thrift Trust are prorated
     to participants based on the unit value calculated at the end of each day.

     Realized gains and losses on the sale of investments are determined using
     the average cost method.

     Net investment income from mutual fund holdings includes dividend income
     and realized and unrealized appreciation/depreciation.

     c.  EXPENSES - The Plan's expenses are accrued as incurred and paid by the
         --------
      Plan, as provided by

                                       9
<PAGE>

     the Plan document.

     d.  USE OF ESTIMATES - The preparation of financial statements in
         ----------------
     conformity with accounting principles generally accepted in the United
     States of America, requires management to make estimates and assumptions
     that affect the reported amounts of net assets available for benefits, and
     changes therein. Actual results could differ from those estimates.

     e.  RECLASSIFICATIONS - The Plan has adopted SOP 99-3 "Accounting and
         -----------------
     Reporting of Certain Defined Contribution Benefit Plan Investments and
     Other Disclosure Matters". As a result, reclassifications have been made to
     eliminate the by-fund disclosure as previously required.

     f.  CONCENTRATION OF INVESTMENTS - Included in the Plan's net assets
         ----------------------------
     available for benefits at June 30, 2000, are investments in Dominion common
     stock amounting to approximately $39 million whose value could be subject
     to change based upon market conditions.

3. INVESTMENTS

     The following presents investments that represent 5% or more of the Plan's
     net assets available for benefits:

                                                    June 30,
                                              2000            1999

  Diversified Equity Fund                 $ 4,946,279    $         -
  Fixed Investment Stable Fund             41,646,597     11,454,579
  Dominion Common Stock                    38,989,453              -
  CNG Stock Fund                                    -     60,807,890


 During July 1, 1999 through June 30, 2000, the Plan's investments (including
 gains and losses on investments bought and sold, as well as held during the
 year) appreciated in value by $9,066,445 as follows:

  Investments at Fair Value:
  --------------------------

  Mutual Funds                                          $8,922,620
  Common/Collective Trust                                   32,312
  Common Stock                                             111,513
                                                        ----------

                                                        $9,066,445
                                                        ==========

4. PLAN TERMINATION


   Although it has not expressed any intention to do so, the Company has the
   right under the Plan to discontinue its contributions at any time and to
   terminate the Plan subject to the provisions set forth in ERISA. In the event
   of any termination of the Plan, or upon complete or partial discontinuance of
   contributions, the accounts of each affected participant shall become fully
   vested.

5. PLAN INTEREST IN CONSOLIDATED NATURAL GAS MASTER TRUST

   A portion of the Plan's investments are in a Master Trust which was
   established for the investment of assets of the Plan and the thrift plans of
   other subsidiaries of the Company. The assets of the Master Trust are held by
   Mellon Bank, N.A., as Trustee of the fund. Each participating thrift plan has
   an undivided

                                       10
<PAGE>

  interest in the Master Trust. The assets and income, including net
  appreciation (depreciation) in fair value of plan assets, are allocated to the
  participating plans based on each plan's proportionate share of the units of
  participation held in the fund each month. As of June 30, 2000 and 1999, the
  Plan's interest in the net assets of the Master Trust was approximately 8.6%
  and .50%, respectively, with varying interests in each of the Funds.

  The following table presents the value of the undivided investments (and
  related investment income) in the Master Trust.

     a)   The Fixed Investment Stable Value Fund holds investments in an
          interest bearing cash fund and in fully benefit-responsive insurance
          investment contracts and separate investment accounts. Insurance
          contracts and accounts are included in the financial statement at
          contract value as reported by the various insurance companies.
          Contract value represents contributions made under the contract, plus
          earnings, less participant withdrawals and administrative expenses.
          Participants may ordinarily direct the withdrawal or transfer of all
          or a portion of their investment in this fund at contract value.

          There are no reserves against contract values for credit risks of the
          contract issuers or otherwise. The average yield and crediting
          interest rates for the years ended June 30, 2000 and 1999 were
          approximately 6.55% and 6.5%, respectively.

     b)   The CNG Stock Fund was replaced by the Dominion Stock Fund on
          February 1, 2000.  The Dominion Stock Fund is not a part of the CNG
          Master Trust.

6. TAX STATUS

     The Plan is a qualified employees' profit sharing trust under Sections
     401(a) and 401(k) of the IRC and, as such, is exempt from federal income
     taxes under Section 501(a).  Pursuant to Section 402(a) of the IRC, a
     participant is not taxed on the income and pretax contributions allocated
     to the participant's account until such time as the participant or the
     participant's beneficiaries receive distributions from the Plan.

     The Plan obtained its latest determination letter on November 8, 1995, in
     which the Internal Revenue

                                       11
<PAGE>

     Service stated that the Plan, as amended through December 27, 1994, was in
     compliance with the applicable requirements of the Internal Revenue Code.
     The Plan has been amended since receiving the determination letter.
     However, the Plan administrator and the Plan's tax counsel believe that the
     Plan is currently designed and is currently operating in compliance with
     the applicable requirements of the Internal Revenue Code.

7.  MERGER OF CNG AND DOMINION

     On February 12, 1999, CNG and Dominion announced that a definitive merger
     agreement was approved by the Boards of Directors of both companies.  On
     May 11, 1999, CNG announced that its Board had unanimously approved an
     amended and restated Agreement and Plan of Merger.  The shareholders of
     both the CNG and Dominion and all applicable state regulatory commissions
     and federal regulatory agencies approved the merger.

     The merger agreement called for a two-step merger process.  The first step,
     the First Merger, allowed shareholders of Dominion common stock to elect to
     exchange their shares for cash, new Dominion shares or a combination of
     cash and shares.  The second step, the Second Merger, allowed shareholders
     of CNG common stock to elect to exchange their old shares for cash or new
     Dominion shares (at a prescribed formula) or a combination of cash and
     shares.

     As directed by the Trustee, Mellon Bank solicited elections from
     participants with respect to shares of stock allocated to their accounts.
     Effective with the completion of the merger, units of participation in the
     CNG Stock Fund were converted to cash and shares of Dominion common stock
     based upon participants' elections (subject to the terms of the merger
     agreement).  The fund was renamed the Dominion Stock Fund.

     The merger was finalized on January 28, 2000 and results were posted to
     participants' accounts on February 14, 2000.

INDEPENDENT AUDITORS' REPORT

To the Trustee and Participants of the
  Virginia Natural Gas, Inc. Employee Savings Plan

We have audited the accompanying statement of net assets available for benefits
of the Virginia Natural Gas, Inc. Employee Savings Plan (the Plan) as of June
30, 2000 and the related statement of changes in net assets available for
benefits for the year ended June 30, 2000. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audit. The financial
statements of the Plan as of June 30, 1999 were audited by other auditors whose
report, dated April 7, 2000 expressed an unqualified opinion on those
statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of June 30, 2000,
and the changes in net assets available for benefits for the year ended June 30,
2000 in conformity with accounting principles generally accepted in the United
States of America.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.

The supplemental schedules listed in the Table of Contents are presented for the
purpose of additional analysis and are not a required part of the basic
financial statements, but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974. These schedules are the
responsibility of the Plan's management. Such schedules have been subjected to
the auditing procedures applied in our audit of the basic 2000 financial
statements and, in our opinion, are fairly stated in all material respects when
considered in relation to the basic financial statements taken as a whole.

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

1.  DESCRIPTION OF PLAN

      The following description of the Virginia Natural Gas, Inc. Employee
      Savings Plan (the Plan) provides only general information.  Participants
      should refer to the Plan document for a more complete description of the
      Plan's provisions.

      a.  GENERAL - The Plan is a defined contribution plan and is the successor
          -------
      to the Virginia Power Employee Savings Plan, which was sponsored by
      Virginia Electric and Power Company (a subsidiary of Dominion Resources,
      Inc. (Dominion). The Employer (Virginia Natural Gas, Inc.) is a wholly
      owned subsidiary of Consolidated Natural Gas Company (the Company or CNG).
      The Plan is subject to the provisions of the Employee Retirement Income
      Security Act of 1974 (ERISA).

      Employee and employer contributions are made pursuant to the terms of the
      plan and are held in funds administered by the Trustees under two
      declarations of trust, i.e., the Long-Term Thrift Trust and the Short-Term
      Thrift Trust (the Trusts). Prior to July 1, 1999, funds were held under
      one declaration of trust - the Alternate Thrift Trust.

      The Trusts are maintained in accordance with the Plan's provision to
      provide for the custody and investment of employee and employer
      contributions. They are administered by individual trustees (the
      "Trustees") who are appointed by and serve at the pleasure of the Company
      for a term of three years. The Trustees are employed by and are officers
      of various subsidiaries of the Company and serve without compensation from
      the Plan or Trusts. Custody of Plan assets resides with Mellon Bank, N.A.
      who also serves as the Plan's Trustee.

      b.  CONTRIBUTIONS - Under the Plan, participants may contribute not less
          -------------
      than 2% and not more than 16% of their earnings each pay period, in
      increments of 1%. If the participant elects that his/her employer make
      pretax contributions on his/her behalf, such contributions cannot exceed
      10%, in increments of 1%, of his/her earnings each pay period subject to
      applicable Internal Revenue Code (IRC) limitations.

      c.  PARTICIPANT ACCOUNTS - Each participant's account includes the effect
          --------------------
      of the participant's contributions and withdrawals, as applicable, and
      allocations of the Company's contributions, Plan earnings, and
      administrative expenses. Allocations are based on participant earnings or
      account balances, as defined. Forfeited balances of terminated
      participants' non-vested accounts are used to reduce future employer
      contributions. The benefit to which a participant is entitled is the
      benefit that can be provided from the participant's account.

      Retired participants may elect to receive an amount equal to their vested
      Long-Term Thrift Trust account balance either in a lump sum or in
      installments. For terminations other than retirements, participants can
      only receive their vested Long-Term Thrift Trust account balance as a lump
      sum distribution. Upon termination and retirement, participants can only
      receive their Short-Term Thrift Trust account balance as a lump sum
      distribution.

      d.  PARTICIPANTS - Participation in the Plan is entirely voluntary.  The
          ------------
      participants in the plan are

                                       6
<PAGE>

     salaried and non-union hourly employees of the Employer who elected to
     continue participation in this plan after June 30, 1991.

     e.  VESTING - Participants immediately vest in their contributions and
         -------
     earnings thereon.  Participants vest in the Employer's matching
     contribution and related earnings based upon years of continuous service
     and are fully vested after five years of credited service.  The Employer's
     matching contribution is based upon the participant's contribution rate.

     f.  INVESTMENT OPTIONS - Upon enrollment in the Plan, a participant may
         ------------------
     direct contributions in any option (except the loan fund) in 1% increments
     totaling to 100%.  Investment options are valued daily.  Changes in
     investment options may be made at any time and become effective with the
     subsequent pay period.  Participants can make unlimited transfers among
     existing funds.  Prior to July 1, 1999, participant contributions could be
     invested in Company common stock or the General Investments Fund.
     Effective July 1, 1999, the Plan provides for employee contributions to be
     invested in the following:

     Short-Term Thrift Trust
     -----------------------

       (1) Interest in CNG Master Trust:

           CNG Short Term Money Market Fund - The Money Market Fund invests
           primarily in U.S. Treasury Bills, U.S. Treasury Notes, corporate
           notes, commercial paper, floating rate notes and repurchase
           agreements.

     Long-Term Thrift Trust
     ----------------------

       (1) Common Stock:

           Dominion Resources, Inc. (Dominion) Stock Fund - All investments are
           in Dominion common stock or cash equivalent investments for partial
           shares. The fund became effective as of February 1, 2000.

       (2) Interest in CNG Master Trust:

           CNG Stock Fund - The fund invested primarily in shares of CNG common
           stock. Participants purchased units of participation in the CNG Stock
           Fund continuously or from funds transferred from other investment
           options. Dividends on Company common stock held in the CNG Stock Fund
           were invested in additional units of the CNG Stock Fund and credited
           to participants' accounts. The fund ceased operations as of February
           1, 2000.

           Fixed Investment Stable Value Fund - The fund invests in group
           annuity contracts with one or more insurance companies and other
           short term fixed income securities. Investments under the contracts
           mature at various intervals. The interest rates, credited daily to
           participants' accounts, represent a composite of the income earned
           under the contracts with the insurance companies and the revenue
           earned from short-term fixed income securities.

                                       7
<PAGE>

         Diversified Equity Fund - The fund invests primarily in the common
         stocks of large U.S. companies.

         (3)  Mutual Funds:

         The Masterworks S&P 500 Index Fund - The fund invests proportionately
         in all or nearly all of the stocks that are included in the Standard &
         Poor's 500 Stock Index.

         The Small Stock Fund - The fund invests in stocks of small to mid-sized
         U.S. companies.

         The International Equity Fund - The fund invests in stocks of companies
         outside the U.S.

         The Intermediate Bond Fund - The fund invests primarily in fixed income
         securities of various maturities such as obligations of the U.S.
         Government, corporate debt securities, mortgage and other asset-backed
         securities and money market investments.

     (4) Common/Collective Trusts:

         The Conservative Balanced Fund, The Moderate Balanced Fund and The
         Growth Balanced Fund - These funds are common/collective trusts and
         each is designed to accomplish a specific investment objective.  As
         such, each fund has a different diversified mix of stock, bond and
         short-term fixed income investments.

     g.  PAYMENTS OF BENEFITS - Distributions from the Plan are recorded on the
         --------------------
     valuation date when a participant's valid withdrawal request is processed
     by the recordkeeper.  On termination of service, a participant may elect to
     receive either a lump sum amount equal to the value of the participant's
     vested interest in his or her account, or defer the payment to a future
     time no later than the year in which the participant attains age 70 1/2.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

       a.  VALUATION OF INVESTMENTS:
           ------------------------

             (1)  Dominion Stock Fund - Investments in Dominion common stock are
                  stated at fair value based on the closing sales price reported
                  on the New York Stock Exchange on the last business day of the
                  plan year.

             (2)  Investment in Consolidated Natural Gas Master Trust - The fair
                  value of the Plan's interest in the Master Trust is based on
                  the beginning of the year value of the Plan's interest in the
                  Master Trust plus actual contributions and allocated
                  investment income less actual distributions and allocated
                  administrative expenses. Quoted market prices are used to
                  value investments in the Master Trust, with the exception of
                  the trust's investment in the Fixed Investment Stable Value
                  Fund.

                                       8
<PAGE>

              Investments in the Fixed Investment Stable Value Fund are stated
              at contract value, which approximates market value. Contract value
              represents contributions and income earned in the fund, less
              withdrawals. The fair market value of the contracts approximates
              the contract value.

              The CNG Stock Fund was stated at market value. Company common
              stock was purchased for participants on the open market, directly
              from the Company and, in certain circumstances, as shares or
              fractional shares from terminating employees' Plan and Employee
              Stock Ownership Plan accounts and other stockholders. Such shares
              or fractional shares were allocated among the accounts of
              participants directing the Trustees to purchase Company common
              stock.

         (3)  Mutual Funds - Investments in mutual funds are valued at quoted
              market prices, which represent the net asset values of shares held
              by the Plan at year-end.

         (4)  Common/Collective Trusts - Investments in common/collective trust
              funds (funds) are stated at estimated fair values, which have been
              determined based on the unit values of the funds. Unit values are
              determined by the bank (or trust company) sponsoring such funds by
              dividing the fund's net assets by its units outstanding at the
              valuation dates.

         b.   INVESTMENT INCOME - Dividend income is recognized on the ex-
              -----------------
         dividend date. Dividends received on all shares of company stock are
         reinvested in additional shares of Dominion common stock (previously in
         shares of CNG common stock).

         Diversified Equity Fund units of the Long-Term Thrift Trust are
         prorated to participants based on the unit value calculated at the end
         of each day.

         Realized gains and losses on the sale of investments are determined
         using the average cost method.

         Net investment income from mutual fund holdings includes dividend
         income and realized and unrealized appreciation/depreciation.

         c.   EXPENSES - The Plan's expenses are accrued as incurred and paid by
              --------
         the Plan, as provided by the Plan document.

         d.   USE OF ESTIMATES - The preparation of financial statements in
              ----------------
         conformity with accounting principles generally accepted in the United
         States of America, requires management to make estimates and
         assumptions that affect the reported amounts of net assets available
         for benefits, and changes therein. Actual results could differ from
         those estimates.

         e.   RECLASSIFICATIONS - The Plan has adopted SOP 99-3 "Accounting and
              -----------------
         Reporting of Certain Defined Contribution Benefit Plan Investments and
         Other Disclosure Matters". As a result, reclassifications have been
         made to eliminate the by-fund disclosure as previously required.

         f.   CONCENTRATION OF INVESTMENTS - Included in the Plan's net assets
              ----------------------------
         available for benefits at June 30, 2000, are investments in Dominion
         common stock amounting to approximately $1.8 million whose value could
         be subject to change based upon market conditions.

  3.  INVESTMENTS

The following presents investments that represent 5% or more of the Plan's net
assets available for benefits:

During July 1, 1999 through June 30, 2000, the Plan's investments (including
gains and losses on investments bought and sold, as well as held during the
year) appreciated in value by $67,889 as follows:

4.  PLAN TERMINATION

       Although it has not expressed any intention to do so, the Company has the
       right under the Plan to discontinue its contributions at any time and to
       terminate the Plan subject to the provisions set forth in ERISA. In the
       event of any termination of the Plan, or upon complete or partial
       discontinuance of contributions, the accounts of each affected
       participant shall become fully vested.

5.  PLAN INTEREST IN CONSOLIDATED NATURAL GAS MASTER TRUST

       A portion of the Plan's investments are in a Master Trust which was
       established for the investment of assets of the Plan and the thrift plans
       of other subsidiaries of the Company. The assets of the Master Trust are
       held by Mellon Bank, N.A., as Trustee of the fund. Each participating
       thrift plan has an undivided interest in the Master Trust. The assets and
       income, including net appreciation (depreciation) in fair value of plan
       assets, are allocated to the participating plans based on each plan's
       proportionate share of the units of participation held in the fund each
       month. As of June 30, 2000 and 1999, the Plan's interest in the net
       assets of the Master Trust was approximately .4% and 0%, respectively,
       with varying interests in each of the funds.

                                                   ============   ============

      a)   The Fixed Investment Stable Value Fund holds investments in an
           interest bearing cash fund and in fully benefit-responsive insurance
           investment contracts and separate investment accounts. Insurance
           contracts and accounts are included in the financial statement at
           contract value as reported by the various insurance companies.
           Contract value represents contributions made under the contract, plus
           earnings, less participant withdrawals and administrative expenses.
           Participants may ordinarily direct the withdrawal or transfer of all
           or a portion of their investment in this fund at contract value.

           There are no reserves against contract values for credit risks of the
           contract issuers or otherwise. The average yield and crediting
           interest rates for the years ended June 30, 2000 and 1999 were
           approximately 6.55% and 6.5%, respectively.

      b)   The CNG Stock Fund was replaced by the Dominion Stock Fund on
           February 1, 2000. The Dominion Stock Fund is not a part of the CNG
           Master Trust.

6.  TAX STATUS

      The Plan is a qualified employees' profit sharing trust under Sections
      401(a) and 401(k) of the IRC and, as such, is exempt from federal income
      taxes under Section 501(a). Pursuant to Section 402(a) of the IRC, a
      participant is not taxed on the income and pretax contributions allocated
      to the participant's account until such time as the participant or the
      participant's beneficiaries receive distributions from the Plan.

      The Plan obtained its latest determination letter on October 18, 1995, in
      which the Internal Revenue Service stated that the Plan, as amended
      through December 22, 1994, was in compliance with the applicable
      requirements of the Internal Revenue Code. The Plan has been amended since
      receiving the determination letter. However, the Plan administrator and
      the Plan's tax counsel believe that the

                                      11
<PAGE>

     Plan is currently designed and is currently operating in compliance with
     the applicable requirements of the Internal Revenue Code.

7.  MERGER OF CNG AND DOMINION

     On February 12, 1999, CNG and Dominion announced that a definitive merger
     agreement was approved by the Boards of Directors of both companies.  On
     May 11, 1999, CNG announced that its Board had unanimously approved an
     amended and restated Agreement and Plan of Merger.  The shareholders of
     both the CNG and Dominion and all applicable state regulatory commissions
     and federal regulatory agencies approved the merger.

     The merger agreement called for a two-step merger process.  The first step,
     the First Merger, allowed shareholders of Dominion common stock to elect to
     exchange their shares for cash, new Dominion shares or a combination of
     cash and shares.  The second step, the Second Merger, allowed shareholders
     of CNG common stock to elect to exchange their old shares for cash or new
     Dominion shares (at a prescribed formula) or a combination of cash and
     shares.

     As directed by the Trustee, Mellon Bank solicited elections from
     participants with respect to shares of stock allocated to their accounts.
     Effective with the completion of the merger, units of participation in the
     CNG Stock Fund were converted to cash and shares of Dominion common stock
     based upon participants' elections (subject to the terms of the merger
     agreement).  The fund was renamed the Dominion Stock Fund.

     The merger was finalized on January 28, 2000 and results were posted to
     participants' accounts on February 14, 2000.
8.  SUBSEQUENT EVENT

     On October 6, 2000, Virginia Natural Gas, Inc. was sold by Consolidated
     Natural Gas Company (and its successor Dominion Resources, Inc.) to AGL
     Resources, Inc. (AGL).  Effective with the sale of VNG stock to AGL, all
     assets in the Plan were transferred to AGL's thrift 401(k) plan.

INDEPENDENT AUDITORS' REPORT

To the Trustee and Participants of the
  Virginia Natural Gas, Inc. Hourly Savings Plan

We have audited the accompanying statement of net assets available for benefits
of the Virginia Natural Gas, Inc. Hourly Savings Plan (the Plan) as of June 30,
2000 and the related statement of changes in net assets available for benefits
for the year ended June 30, 2000.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to express an
opinion on these financial statements based on our audit.  The financial
statements of the Plan as of June 30, 1999 were audited by other auditors whose
report, dated April 7, 2000 expressed an unqualified opinion on those
statements.

We conducted our audit in accordance with auditing standards generally accepted
in the United States of America.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation.  We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the net assets available for benefits of the Plan as of June 30, 2000,
and the changes in net assets available for benefits for the year ended June 30,
2000 in conformity with accounting principles generally accepted in the United
States of America.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole.  The supplemental schedules listed in the
Table of Contents are presented for the purpose of additional analysis and are
not a required part of the basic financial statements, but are supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974.  These schedules are the responsibility of the Plan's management. Such
schedules have been subjected to the auditing procedures applied in our audit of
the basic 2000 financial statements and, in our opinion, are fairly stated in
all material respects when considered in relation to the basic financial
statements taken as a whole.

VIRGINIA NATURAL GAS, INC.
HOURLY SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS
--------------------------------------------------------------------------------

1.  DESCRIPTION OF PLAN

     The following description of the Virginia Natural Gas, Inc. Hourly Savings
     Plan (the Plan) provides only general information. Participants should
     refer to the Plan document for a more complete description of the Plan's
     provisions.

     a.  GENERAL - The Plan is a defined contribution plan and is the successor
         -------
     to the Virginia Power Hourly Employee Savings Plan, which was sponsored by
     Virginia Electric and Power Company (a subsidiary of Dominion Resources,
     Inc. (DRI). The employer is a wholly owned subsidiary of Consolidated
     Natural Gas Company (the Company or CNG). The Plan is subject to the
     provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

     Employee and employer contributions are made pursuant to the terms of the
     plan and are held in funds administered by the Trustees under two
     declarations of trust, i.e., the Long-Term Thrift Trust and the Short-Term
     Thrift Trust (the Trusts).

     The Trusts are maintained in accordance with the Plan's provision to
     provide for the custody and investment of employee and employer
     contributions. They are administered by individual trustees (the Trustee)
     who are appointed by and serve at the pleasure of the Company for a term of
     three years. The Trustees are employed by and are officers of various
     subsidiaries of the Company and serve without compensation from the Plan or
     Trusts. Custody of Plan assets resides with Mellon Bank, N.A. who also
     serves as the Plan's Trustee.

     b.  CONTRIBUTIONS - Under the Plan, participants may contribute not less
         -------------
     than 2% and not more than 16% (15% for participants with thirty or more
     years of service) of their earnings each pay period, in increments of 1%.
     If the participant elects that his employer make pretax contributions on
     his behalf, such contributions cannot exceed 10%, in increments of 1%, of
     his earnings each pay period subject to applicable Internal Revenue Code
     (IRC) limitations.

     c.  PARTICIPANT ACCOUNTS - Each participant's account includes the effect
         --------------------
     of the participant's contributions and withdrawals, as applicable, and
     allocations of the Company's contributions, Plan earnings, and
     administrative expenses.  Allocations are based on participant earnings or
     account balances, as defined.  Forfeited balances of terminated
     participants' non-vested accounts are used to reduce future employer
     contributions.  The benefit to which a participant is entitled is the
     benefit that can be provided from the participant's account.

     Retired participants may elect to receive an amount equal to their vested
     Long-Term Thrift Trust account balance either in a lump sum or in
     installments. For terminations other than retirements, participants can
     only receive their vested Long-Term Thrift Trust account balance as a lump
     sum distribution. Upon termination and retirement, participants can only
     receive their Short-Term Thrift Trust account balance as a lump sum
     distribution.

                                       6
<PAGE>

     d.  PARTICIPANTS - Each employee is eligible to participate in the Plan on
         ------------
     an entirely voluntary basis.  The participants in the Plan are union-
     eligible hourly employees of Virginia Natural Gas, Inc. (the Employer).
     Participation by an employee becomes effective immediately upon completion
     and delivery to the Employer (or the Company) of an authorization form
     furnished by the Employer.

     e.  VESTING - Participants immediately vest in their contributions and
         -------
     earnings thereon.  Participants vest in the Employer's matching
     contribution and related earnings based upon years of continuous service
     and are fully vested after five years of credited service.  The Employer's
     matching contribution is based upon the participant's contribution rate and
     length of service.

     f.  INVESTMENT OPTIONS - Upon enrollment in the Plan, a participant may
         ------------------
     direct contributions in any option (except the loan fund) in 1% increments
     totaling to 100%.  Investment options are valued daily.  Changes in
     investment options may be made at any time and become effective with the
     subsequent pay period.  Participants can make unlimited transfers among
     existing funds.  Prior to July 1, 1999, participants could invest in 1)
     Company common stock, 2) General Investments Fund, 3) Conservative Balanced
     Fund, 4) Moderate Balanced Fund and/or 5) Growth Balanced Fund.  Effective
     July 1, 1999, the Plan provides for employee and employer contributions to
     be invested in the following:

     Short-Term Thrift Trust
     -----------------------

     (1)  Interest in CNG Master Trust:

         CNG Short Term Money Market Fund - The Money Market Fund invests
         primarily in U.S. Treasury Bills, U.S. Treasury Notes, corporate notes,
         commercial paper, floating rate notes and repurchase agreements.

     Long-Term Thrift Trust
     ----------------------

     (1)  Common Stock:

         Dominion Resources, Inc. (Dominion) Stock Fund - All investments are in
         Dominion common stock or cash equivalent investments for partial
         shares.  The fund became effective as of February 1, 2000.

     (2)  Interest in CNG Master Trust:

         CNG Stock Fund - The fund invested primarily in shares of CNG common
         stock.  Participants purchased units of participation in the CNG Stock
         Fund continuously or from funds transferred from other investment
         options.  Dividends on Company common stock held in the CNG Stock Fund
         were invested in additional units of the CNG Stock Fund and credited to
         participants' accounts.  The fund ceased operations as of February 1,
         2000.

         Fixed Investment Stable Value Fund - The fund invests in group annuity
         contracts with one or more insurance companies and other short term
         fixed income securities.  Investments under the contracts mature at
         various intervals.  The interest rates, credited daily to participants'
         accounts, represent a composite of the income earned

                                       7
<PAGE>

         under the contracts with the insurance companies and the revenue earned
         from short-term fixed income securities.

         Diversified Equity Fund - The fund invests primarily in the common
         stocks of large U.S. companies.

    (3)  Mutual Funds:

         The Masterworks S&P 500 Index Fund - The fund invests proportionately
         in all or nearly all of the stocks that are included in the Standard &
         Poor's 500 Stock Index.

         The Small Stock Fund - The fund invests in stocks of small to mid-sized
         U.S. companies.

         The International Equity Fund - The fund invests in stocks of companies
         outside the U.S.

         The Intermediate Bond Fund - The fund invests primarily in fixed income
         securities of various maturities such as obligations of the U.S.
         Government, corporate debt securities, mortgage and other asset-backed
         securities and money market investments.

    (4)  Common/Collective Trusts:

         The Conservative Balanced Fund, The Moderate Balanced Fund and the
         Growth Balanced Fund - These funds are common/collective trusts and
         each is designed to accomplish a specific investment objective.  As
         such, each fund has a different diversified mix of stock, bond and
         short-term fixed income investments.

   g. PARTICIPANT LOANS - Participants are eligible to secure loans against
      -----------------
   their plan account and repay the amount over a one to five-year period.
   The maximum loan amount is the lesser of:

     .    3 months base pay or
     .    50% of the vested account balance or
     .    $50,000 (reduced by the maximum outstanding loan balance during the
          prior 12 months).

     Loan transactions are treated as a transfer between the respective
     investment fund and the loan fund. The loans bear fixed interest at a rate
     commensurate with local prevailing rates at the time the loan is issued as
     determined by the Trustees.

     Participants make repayments to the Plan on a monthly basis. Loan
     repayments, including interest, are deposited in the participant's account
     and invested in accordance with the participant's then current investment
     elections. Defaults result in a reclassification of the remaining loan
     balances as taxable distributions to the participants.

   h.  PAYMENTS OF BENEFITS - Distributions from the Plan are recorded on the
       ---------------------
   valuation date when a participant's valid withdrawal request is processed by
   the recordkeeper. On termination of service, a participant may elect to
   receive either a lump sum amount equal to the value of the

                                       8
<PAGE>

     participant's vested interest in his or her account, or defer the payment
     to a future time no later than the year in which the participant attains
     age 70 1/2.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      a.  VALUATION OF INVESTMENTS:
          ------------------------
          (1)  Dominion Stock Fund - Investments in Dominion common stock are
          stated at fair value based on the closing sales price reported on the
          New York Stock Exchange on the last business day of the plan year.

          (2)  Investment in Consolidated Natural Gas Master Trust - The fair
          value of the Plan's interest in the Master Trust is based on the
          beginning of the year value of the Plan's interest in the Master Trust
          plus actual contributions and allocated investment income less actual
          distributions and allocated administrative expenses. Quoted market
          prices are used to value investments in the Master Trust, with the
          exception of the trust's investment in the Fixed Investment Stable
          Value Fund.

          Investments in the Fixed Investment Stable Value Fund are stated at
          contract value, which approximates market value. Contract value
          represents contributions and income earned in the fund, less
          withdrawals. The fair market value of the contracts approximates the
          contract value.

          The CNG Stock Fund was stated at market value. Company common stock
          was purchased for participants on the open market, directly from the
          Company, and in certain circumstances, as shares or fractional shares
          from terminating employees' Plan and Employee Stock Ownership Plan
          accounts and other stockholders. Such shares or fractional shares were
          allocated among the accounts of participants directing the Trustees to
          purchase Company common stock.

          (3)  Mutual Funds - Investments in mutual funds are valued at quoted
          market prices, which represent the net asset values of shares held by
          the Plan at year-end.

          (4)  Common/Collective Trusts - Investments in common/collective trust
          funds (funds) are stated at estimated fair values, which have been
          determined based on the unit values of the funds. Unit values are
          determined by the bank (or trust company) sponsoring such funds by
          dividing the fund's net assets by its units outstanding at the
          valuation dates.

      b.  INVESTMENT INCOME - Dividend income is recognized on the ex-dividend
          -----------------
      date. Dividends received on all shares of company stock are reinvested in
      additional shares of Dominion common stock (previously in shares of CNG
      common stock).

      Diversified Equity Fund units of the Long-Term Thrift Trust are prorated
      to participants based on the unit value calculated at the end of each day.

      Realized gains and losses on the sale of investments are determined using
      the average cost method.

      Net investment income from mutual fund holdings includes dividend income
      and realized and unrealized appreciation/depreciation.

      c.  EXPENSES - The Plan's expenses are accrued as incurred and paid by the
          --------
      Plan, as provided by the Plan document.

      d.  USE OF ESTIMATES - The preparation of financial statements in
          ----------------
      conformity with accounting principles generally accepted in the United
      States of America, requires management to make

                                       9
<PAGE>

      estimates and assumptions that affect the reported amounts of net assets
      available for benefits, and changes therein. Actual results could differ
      from those estimates.

      e.  RECLASSIFICATIONS - The Plan has adopted SOP 99-3 "Accounting and
          -----------------
      Reporting of Certain Defined Contribution Benefit Plan Investments and
      Other Disclosure Matters". As a result, reclassifications have been made
      to eliminate the by-fund disclosure as previously required.

      f.  CONCENTRATION OF INVESTMENTS - Included in the Plan's net assets
          ----------------------------
      available for benefits at June 30, 2000, are investments in Dominion
      common stock amounting to approximately $2.4 million whose value could be
      subject to change based upon market conditions.

3.  INVESTMENTS

The following presents investments that represent 5% or more of the Plan's net
assets available for benefits:

                                                             June 30,
                                                       2000           1999

     Fixed Investment Stable Fund                   1,141,485      1,057,924
     Dominion Common Stock                          2,400,357              -
     S&P 500 Index Fund                               437,098              -
     CNG Stock Fund                                         -      2,332,355


      During July 1, 1999 through June 30, 2000, the Plan's investments
      (including gains and losses on investments bought and sold, as well as
      held during the year) appreciated in value by $353,341 as follows:

4.  PLAN TERMINATION

      Although it has not expressed any intention to do so, the Company has the
      right under the Plan to discontinue its contributions at any time and to
      terminate the Plan subject to the provisions set forth in ERISA. In the
      event of any termination of the Plan, or upon complete or partial
      discontinuance of contributions, the accounts of each affected participant
      shall become fully vested.

5.  PLAN INTEREST IN CONSOLIDATED NATURAL GAS MASTER TRUST

      A portion of the Plan's investments are in a Master Trust which was
      established for the investment of assets of the Plan and the thrift plans
      of other subsidiaries of the Company. The assets of the Master Trust are
      held by Mellon Bank, N.A., as Trustee of the fund. Each participating
      thrift plan has an undivided interest in the Master Trust. The assets and
      income, including net appreciation (depreciation) in fair value of plan
      assets, are allocated to the participating plans based on each plan's
      proportionate share of the units of participation held in the fund each
      month. As of June 30, 2000 and 1999, the Plan's interest in the net assets
      of the Master Trust was approximately .2% and 0%, respectively, with
      varying interests in each of the funds.

     a)   The Fixed Investment Stable Value Fund holds investments in an
          interest bearing cash fund and in fully benefit-responsive insurance
          investment contracts and separate investment accounts. Insurance
          contracts and accounts are included in the financial statement at
          contract value as reported by the various insurance companies.
          Contract value represents contributions made under the contract, plus
          earnings, less participant withdrawals and administrative expenses.
          Participants may ordinarily direct the withdrawal or transfer of all
          or a portion of their investment in this fund at contract value.

          There are no reserves against contract values for credit risks of the
          contract issuers or otherwise. The average yield and crediting
          interest rates for the years ended June 30, 2000 and 1999 were
          approximately 6.55% and 6.5%, respectively.

      b)  The CNG Stock Fund was replaced by the Dominion Stock Fund on February
          1, 2000. The Dominion Stock Fund is not a part of the CNG Master
          Trust.

6.  TAX STATUS

      The Plan is a qualified employees' profit sharing trust under Sections
      401(a) and 401(k) of the IRC and, as such, is exempt from federal income
      taxes under Section 501(a). Pursuant to Section 402(a) of the IRC, a
      participant is not taxed on the income and pretax contributions allocated
      to the participant's account until such time as the participant or the
      participant's beneficiaries receive distributions from the Plan.

      The Plan obtained its latest determination letter on October 18, 1995 in
      which the Internal Revenue Service stated that the Plan, as amended
      through January 1, 1995 was in compliance with the applicable requirements
      of the Internal Revenue Code. The Plan has been amended since receiving
      the determination letter. However, the Plan administrator and the Plan's
      tax counsel believe that the Plan is currently designed and is currently
      operating in compliance with the applicable requirements of the Internal
      Revenue Code.

7.  MERGER OF CNG AND DOMINION

     On February 12, 1999, CNG and Dominion announced that a definitive merger
     agreement was approved by the Boards of Directors of both companies.  On
     May 11, 1999, CNG announced that its Board had unanimously approved an
     amended and restated Agreement and Plan of Merger.  The shareholders of
     both the CNG and Dominion and all applicable state regulatory commissions
     and federal regulatory agencies approved the merger.

     The merger agreement called for a two-step merger process.  The first step,
     the First Merger, allowed shareholders of Dominion common stock to elect to
     exchange their shares for cash, new Dominion shares or a combination of
     cash and shares.  The second step, the Second Merger, allowed shareholders
     of CNG common stock to elect to exchange their old shares for cash or new
     Dominion shares (at a prescribed formula) or a combination of cash and
     shares.

     As directed by the Trustee, Mellon Bank solicited elections from
     participants with respect to shares of stock allocated to their accounts.
     Effective with the completion of the merger, units of participation in the
     CNG Stock Fund were converted to cash and shares of Dominion common stock
     based upon participants' elections (subject to the terms of the merger
     agreement).  The fund was renamed the Dominion Stock Fund.

     The merger was finalized on January 28, 2000 and results were posted to
     participants' accounts on February 14, 2000.

8.  SUBSEQUENT EVENT

     On October 6, 2000, Virginia Natural Gas, Inc. was sold by Consolidated
     Natural Gas Company (and its successor Dominion Resources, Inc.) to AGL
     Resources, Inc. (AGL).  Effective with the sale of VNG stock to AGL, all
     assets in the Plan were transferred to AGL's thrift 401(k) plan.
