                               WGL HOLDINGS, INC.

"Corporation").

         SECOND: The purpose of the Corporation is to engage in any lawful act
or activity not required to be specifically stated in these Articles of
Incorporation ("Articles") for which corporations may be organized under the
laws of the Commonwealth of Virginia.

         THIRD:  (a) The aggregate number of shares which the Corporation is
authorized to issue and the par value per share are as follows:

<TABLE>
<CAPTION>
                CLASS       NUMBER OF SHARES          PAR VALUE
             ---------      ----------------        -----------
<S>                        <C>                     <C>

             Preferred         3,000,000            No Par Value
</TABLE>

                  (b) The Board of Directors of the Corporation shall have the
         authority to fix, in whole or in part, the preferences, limitations
         and relative rights, within the limits set by law, of (i) any class
         of shares before the issuance of any shares of that class, or (ii)
         one or more series within a class before the issuance of any shares
         of that series.

                  (c) The holders of common stock, to the exclusion of any
         other class of stock of the Corporation, have sole and full power to
         vote for the election of directors and for all other purposes without
         limitation except only (i) as otherwise expressly provided in the
         serial designation of any series of preferred stock, (ii) as
         otherwise expressly provided in these Articles or (iii) as otherwise
         expressly provided by the then existing laws of the Commonwealth of
         Virginia. In the election of directors and in all other matters as to
         which the shareholders shall be entitled to vote, the holders of
         common stock will be entitled to one vote for each share of common
         stock held by them. The outstanding shares of common stock, upon
         dissolution, liquidation or winding up of the Corporation, entitle
         their holders to share, pro rata, based on the number of shares
         owned, in the Corporation's assets remaining after payment or
         provisions for payment of all debts and liabilities of the
         Corporation, and after provisions for the outstanding shares of any
         class of stock or other security having senior liquidation rights to
         the common stock.

                  (d) No holder of shares of stock of any class of the
         Corporation will have any preemptive or preferential right of
         subscription to any shares of any class of stock of the Corporation,
         whether now or hereafter authorized, or to any obligations of the
         Corporation convertible into stock of the Corporation, issued or
         sold, nor any right of subscription to any thereof.

         FOURTH:  Subject to the rights of holders of any series of preferred
stock to elect directors under specified circumstances:

                  (a) The number of directors of the Corporation shall consist
        of one or more individuals as may be fixed from time to time by
        resolution of the Board of Directors of the Corporation.

                  (b) Any action required or permitted by these Articles of
        Incorporation to be taken by the Board of Directors may be taken by a
        duly authorized committee of the Board of Directors, except as
        otherwise required by law.

         FIFTH: No director or officer of the Corporation shall be liable to
the Corporation or its shareholders for any monetary damages for any action
taken or any failure to take any action as a director or officer; provided,
however, that nothing herein shall be deemed to eliminate or limit any
liability which may not be so eliminated or limited under the laws of the
Commonwealth of Virginia, as in effect at the effective date of these Articles
of Incorporation or as thereafter amended. No amendment, modification or
repeal of this ARTICLE FIFTH shall eliminate or limit the protection afforded
to a officer or director with respect to any act or omission occurring before
the effective date hereof.

         SIXTH: (a) The Corporation shall, to the maximum extent permitted by
applicable law, as from time to time in effect, indemnify any person who was,
is or is threatened to be named as a defendant or respondent in or otherwise
involved in any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative and whether formal or
informal, including without limitation any such action, suit or proceeding by
or in the right of the Corporation to procure a judgment in its favor (any
such action, suit or proceeding being herein called a "Proceeding"), because
he or she is or was a director or officer of the Corporation or because he or
she, while a director or officer of the Corporation, is or was serving at the
Corporation's request as a director, officer, partner, trustee, employee or
agent of another foreign or domestic corporation, partnership, joint venture,
trust, employee benefit plan or any other entity or enterprise, against any
and all judgments, settlements, penalties, fines, including any excise tax
assessed with respect to an employee benefit plan, and/or reasonable expenses
(including counsel fees) incurred with respect to a Proceeding or any appeal
therein.

                  (b) The Corporation shall pay any such expenses incurred by
        a director or officer, or former director or officer, of the
        Corporation in connection with any such Proceeding in advance of the
        final disposition thereof upon receipt of an undertaking by or on
        behalf of such person to repay such advances to the extent of the
        amount to which such person shall ultimately be determined not to be
        entitled and upon satisfaction of such other conditions as may be
        required by applicable law.

                  (c) The Corporation, by resolution of the Board of
        Directors, may extend the benefits of this Article SIXTH to current
        and/or former employees, agents and other representatives of the
        Corporation (each person entitled to benefits under this Article SIXTH
        being hereinafter sometimes called an "Indemnified Person").

                  (d) All rights to indemnification and to the advancement of
        expenses granted under or pursuant to this Article SIXTH shall be
        deemed to arise out of a contract between the Corporation and each
        person who is an Indemnified Person at any time while this Article
        SIXTH is in effect and may be evidenced by a separate contract between
        the Corporation and each Indemnified Person; and such rights shall be
        effective in respect of all Proceedings commenced after the effective
        date of these Articles of Incorporation, whether arising from acts or
        omissions occurring before or after such date. No amendment,
        modification or repeal of this Article SIXTH shall affect any rights
        or obligations theretofore existing.

                  (e) The Corporation may purchase and maintain insurance on
        behalf of, or insure or cause to be insured, any person who is an
        Indemnified Person against any liability asserted against or incurred
        by him or her in any capacity in respect of which he or she is an
        Indemnified Person, or arising out of his or her status in such
        capacity, whether or not the Corporation would have the power to
        indemnify him or her against such liability under this Article SIXTH.
        As used in this Section "insurance" includes retrospectively rated and
        self-insured programs; provided, however that no such program shall
        provide coverage for directors and officers which is prohibited by
        applicable law. The Corporation's indemnity of any person who is an
        Indemnified Person shall be reduced by any amounts such person may
        collect with respect to such liability (1) under any policy of
        insurance purchased and maintained on his or her behalf by the
        Corporation or (2) from any other entity or enterprise served by such
        person.

                  (f) The rights to indemnification and to the advancement of
        expenses and all other benefits provided by, or granted pursuant to,
        this Article SIXTH shall continue as to a person who

                                    - 2 -

<PAGE>   3

        has ceased to serve in the capacity in respect of which such person
        was an Indemnified Person and shall inure to the benefit of the heirs,
        executors and administrators of such person.

                  (g) The indemnification and advancement of expenses provided
         by, or granted pursuant to, this Article SIXTH shall not be deemed
         exclusive of any other rights to which any Indemnified Person may be
         entitled under any statute or court order or any Bylaw, agreement,
         vote of shareholders or disinterested directors or otherwise.

                  (h) The Board of Directors shall have the power and
         authority to make, alter, amend and repeal such procedural rules and
         regulations relating to indemnification and the advancement of
         expenses as it, in its discretion, may deem necessary or expedient in
         order to carry out the purposes of this Article SIXTH, such rules and
         regulations, if any, to be set forth in the Bylaws of the Corporation
         or in a resolution of the Board of Directors.

                  2.         A "person" includes any individual, firm,

                  3. "Voting Stock" includes those issued and outstanding
        shares of the stock of the Corporation entitled to vote generally in
        the election of Directors but shall not include any shares which may

                  4. "Affiliate" or "associate" shall have the respective
         meanings ascribed to such terms in Rule 12b-2 of the General Rules
         and Regulations under the Securities Exchange Act of 1934, as
         amended.

                           b.       have (i) the right to acquire Voting Stock
                  (whether such right may be exercised immediately or only

                  arrangement, or understanding or upon the exercise of
                  conversion rights, exchange rights, warrants, or options, or
                  (ii) the right to vote Voting Stock pursuant to any

         the Corporation or any Subsidiary) who or which:

                           a.       is the beneficial owner, directly or

                  date in question was the beneficial owner, directly or
                  indirectly, of more than 10% of the Voting Stock; or

                  date in question beneficially owned by any Interested
                  Shareholder, if such assignment or succession shall have
                  occurred in the course of a transaction or series of
                  transactions not involving a public offering within the
                  meaning of the Securities Act of 1933, as amended.

                  7.       A "Subsidiary" is any corporation of which a
         majority of any class of equity security is owned, directly or
         indirectly, by the Corporation, provided that, for purposes of the
         definition of Interested Shareholder set forth in B-6 above, the term
         "Subsidiary" shall mean only a corporation of which a majority of
         each class of equity security is owned, directly or indirectly, by
         the Corporation.

                  8.       A "Continuing Director" is any member of the Board
         of Directors of the Corporation (the Board) who is unaffiliated with
         the Interested Shareholder and was a member of the Board immediately
         prior to the time that the Interested Shareholder became an
         Interested Shareholder, and any successor of a Continuing Director
         who is unaffiliated with the Interested Shareholder and is
         recommended to succeed a Continuing Director by a majority of
         Continuing Directors then on the Board.

                  9.       "Fair Market Value" means:

                           a.       in the case of stock, the highest closing
                  price during the 30-day period immediately preceding the
                  date in question of a share of such stock on the Composite
                  Tape for New York Stock Exchange Listed Stock; or, if such
                  stock is not quoted on the Composite Tape, on the New York
                  Stock Exchange; or, if such stock is not listed on such
                  exchange, on the principal securities exchange registered
                  under the Securities Exchange Act of 1934, as amended, on
                  which such stock is listed; or, if such stock is not listed
                  on any such exchange, the highest closing-bid quotation with
                  respect to a share of such stock during the 30-day period
                  preceding the date in any system then in use; or, if no such
                  quotation for a share of such stock is available, a fair
                  price as determined by the Board in good faith; and

                           b.       the case of property other than cash or
                  stock, the fair market value of such property on the date in
                  question as determined by the Board in good faith.

                  10.      If the Corporation survives in any Business
         Combination, the phrase "consideration other than cash to be
         received" as used in Paragraph E shall include shares of Common Stock
         of the Corporation and/or the shares of any other class of stock of
         the Corporation entitled to vote generally in election of Directors.

         C.       POWERS OF THE BOARD OF DIRECTORS. The Board shall have the
power to determine, after reasonable inquiry, (1) whether a person is an
Interested Shareholder, (2) the number of shares of Voting Stock beneficially
owned by any person, (3) whether a person is an affiliate or associate of
another, and (4) whether the assets which are the subject of any Business
Combination have, or the consideration to be received for the issuance or
transfer of securities by the Corporation or any Subsidiary in any Business
Combination has, an aggregate Fair Market Value of $1,000,000 or more.

         D.       REQUIRED SHAREHOLDER APPROVAL OF A BUSINESS COMBINATION. In
addition to any affirmative vote required by law or other provision of these
Articles, the consummation of any Business Combination shall require the
affirmative vote of the holders of at least 80% of the shares of the
outstanding Voting Stock, voting together as a single class. For purposes of
this Article SEVENTH, each share of the Voting Stock shall have the number of
votes granted to it pursuant to Article THIRD, paragraph (c) of these
Articles. Such vote shall be taken at a duly called Annual Meeting or Special
Meeting of Shareholders. Such affirmative vote shall be required
notwithstanding the fact that no vote may be required by law or that a lesser
percentage may be specified by law, an agreement with any national securities
exchange, or otherwise.

         E.       WHEN VOTE SPECIFIED IN PARAGRAPH D IS NOT REQUIRED.  The
provisions of Paragraph D shall not be applicable to any Business Combination,
and such Business Combination shall require only such affirmative vote as is
required by law or other provision of these Articles, if:

                  1.       the Business Combination shall have been approved
         by a majority of the Continuing Directors; or

                  2.       the following Minimum Price Condition and Specified
         Conditions have been met:

                           a.       As to the Minimum Price Condition, the
                  following standards of fairness must be met:

                                    (1) COMMON STOCK. As of the date of the
                           consummation of the Business Combination, the
                           aggregate amount of the cash and the Fair Market
                           Value of consideration other than cash to be
                           received per share by holders of the Corporation's
                           Common Stock upon the consummation of such Business
                           Combination shall be at least equal to the highest
                           of:

                                            (a) the highest per-share price
                                    (including any brokerage commissions,
                                    transfer taxes, and soliciting dealers'
                                    fees) paid by the Interested Shareholder

the Board of Directors, in order to make a determination of shareholders
entitled to notice of or to vote at any meeting, or to receive payment of any
dividends or for any other proper purpose, may fix in advance a date, but not
more than seventy days in advance, as a record date for such determination,
and in such case only shareholders of record on the date so fixed shall be
entitled to notice of, and to vote at, such meeting, or to receive payment of
such dividend, or to exercise such other rights, as the case may be,
notwithstanding any transfer of stock on the books of the Company after such
date. If the Board of Directors does not fix a record date as aforesaid, such
date shall be as provided by law.

         SECTION 9. NOTICE OF BUSINESS. At any meeting of the shareholders,
only such business shall be conducted as shall have been brought before the

giving of the notice as provided for in this Section 9, who shall be entitled
to vote at such meeting and who complies with the following procedures:

                 REQUIREMENT OF TIMELY NOTICE. For business to be properly
         brought before a meeting of shareholders by a shareholder, the

         however, if no notice is given and no public announcement is made to
         the shareholders regarding the date of the meeting at least 75 days
         prior to the meeting, the shareholder's notice shall be valid if

         executive office of the Company not less than fifteen (15) days
         following the day on which the notice or public announcement of the

         the provisions of these Bylaws, and if he or she should so determine,
         he or she shall so declare to the meeting and any such business not

         a shareholder shall also comply with all applicable requirements of
         the Securities Exchange Act of 1934, as amended, and the rules and
         regulations thereunder with respect to the matters set forth in this
         Section 9.

                  EFFECTIVE DATE OF SHAREHOLDER BUSINESS. Notwithstanding
         anything in these Bylaws to the contrary, no business brought before
         a meeting of the shareholders by a shareholder shall become effective
         until the final termination of any proceeding which may have been
         commenced in any court of competent jurisdiction for an adjudication
         of any legal issues incident to determining the validity of such
         business and the procedure pursuant to which it was brought before
         the shareholders, unless and until such court shall have determined
         that such proceedings are not being pursued expeditiously and in good
         faith.

         nominated in accordance with the procedures set forth in this section

         court of competent jurisdiction for an adjudication of any legal
         issues incident to determining the procedure pursuant to which the
         nomination of such director was brought before the shareholders,
         unless and until such court shall have determined that such
         proceedings are not being pursued expeditiously and in good faith.

         SECTION 3.        VACANCIES.   If a vacancy occurs on the board of
directors, including a vacancy resulting from an increase in the number of
directors:

         (a)      the shareholders may fill the vacancy;

         (b)      the board of directors may fill the vacancy; or

         (c) if the directors remaining in office constitute fewer than a

majority of directors remaining in office.

         A vacancy that will occur at a specific later date, by reason of a
resignation effective at a later date, may be filled before the vacancy occurs
but the new director may not take office until the vacancy occurs.

         A director elected to fill a vacancy shall be elected for the
unexpired term of his or her predecessor in office. A director filling a
position resulting from an increase in the number of directors shall hold

Directors in the management of the business and affairs of the Company.

         The Board of Directors may appoint other committees, standing or
special, from time to time, from among their own number, or otherwise, and
confer powers on such committees, and revoke such powers and terminate the
existence of such committees at its pleasure.

         A majority of the members of any such committee shall constitute a
quorum for the purpose of fixing the time and place of its meetings, unless
the Board shall otherwise provide. All action taken by any such committee
shall be reported to the Board at its meeting next succeeding such action.

         SECTION 6. COMPENSATION OF DIRECTORS. The Board of Directors shall

the Board of Directors and shall consist of a Chairman of the Board, a

other officers as the Board from time to time shall elect, with such duties as
the Board shall deem necessary to conduct the business of the Company. Any
officer may hold two or more offices (including those of the Chairman of the
Board and President) except that the offices of President and Secretary may
not be held by the same person. The Chairman of the Board shall be a director;

Board present, in terms of service on the Board, shall serve as Chairman pro
tem of the meeting.

         SECTION 4. SALARIES.  The salaries of all executive officers of the
Company shall be determined and fixed by the Board of Directors, or pursuant

                                  ARTICLE IV

                  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         SECTION 1. Any indemnification (unless ordered by a court) shall be
made by the Company only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstance because the person was not finally adjudged in
any threatened, pending or completed action, suit or proceeding (an "Action")
to have knowingly violated criminal law or was not liable for willful
misconduct in the performance of the person's duty to the Company. In the case
of any director, such determination shall be made: (1) by the Board of
Directors by a majority vote of a quorum consisting of directors who were not
parties to such Action; or (2) if such a quorum is not obtainable, by majority
vote of a committee duly designated by the Board of Directors (in which
designation directors who are parties may participate) consisting solely of
two or more directors not at the time parties to the proceeding; or (3) by
special legal counsel selected by the Board of Directors or its committee in
the manner prescribed by clause (1) or (2) of this paragraph, or if such a
quorum is not obtainable and such a committee cannot be designated, by
majority vote of the Board of Directors, in which selection directors who are
parties may participate; or (4) by vote of the shareholders, in which vote
shares owned by or voted under the control of directors, officers and
employees who are at the time parties to the Action may not be voted. In the
case of any officer, employee, or agent other than a director, such
determination may be made (i) by the Board of Directors or a committee
thereof; (ii) by the Chairman of the Board of the Company or, if the Chairman
is a party to such Action, the President of the Company, or (iii) such other
officer of the Company, not a party to such Action, as such person specified
in clause (i) or (ii) of this paragraph may designate. Authorization of
indemnification and evaluation as to reasonableness of expenses shall be made
in the same manner as the determination that indemnification is permissible,
except that if the determination is made by special legal counsel,
authorization of indemnification and evaluation as to reasonableness of
expenses shall be made by those entitled hereunder to select such legal
counsel.

         It is the intention of the Company that the indemnification set forth
in this Section of Article IV, shall be applied to no less extent than the
maximum indemnification permitted by law. In the event that any right to
indemnification or other right hereunder may be deemed to be

                                    - 7 -

<PAGE>   8

unenforceable or invalid, in whole or in part, such unenforceability or
invalidity shall not affect any other right hereunder, or any right to the
extent that is not deemed to be unenforceable. The indemnification provided
herein shall be in addition to, and not exclusive of, any other rights to
which those indemnified may be entitled under the articles of incorporation,
any Bylaw, agreement, vote of shareholders, or otherwise, and shall continue
as to a person who has ceased to be a director, officer, employee, or agent
and inure to the benefit of such person's heirs, executors, and
administrators.

                                  ARTICLE V

                             CHECKS, NOTES, ETC.

         SECTION 1. All checks and drafts on the Company's bank accounts and
all bills of exchange and promissory notes, and all acceptances, obligations
and other instruments for the payment of money, shall be signed by such
officer or officers, agent or agents, as shall be thereunto authorized from
time to time by the Board of Directors.

         SECTION 2. Shares of stock and other interests in other corporations
or associations shall be voted by such officer or officers as the Board of
Directors may designate.

         SECTION 3. Except as the Board of Directors shall otherwise provide,
all contracts expressly approved by the Board shall be signed on behalf of the
Company by the Chairman of the Board, the President, or a Vice President.

                                  ARTICLE VI

                                CAPITAL STOCK.

         SECTION 1. CERTIFICATE FOR SHARES. The interest of each shareholder
of the Company shall be evidenced by a certificate or certificates for shares
of stock in such form as required by law and as the Board of Directors may
from time to time prescribe. The certificates of stock shall be signed by the
President or a Vice President and the Secretary or an Assistant Secretary and
sealed with the seal of the Company. Such seal may be a facsimile.

         Where any such certificate is countersigned by a transfer agent other
than the Company, or an employee of the Company, or is countersigned by a
transfer clerk and is registered by a registrar, the signatures of the
President or Vice President and the Secretary or Assistant Secretary may be
facsimiles.

         In case any officer who has signed, or whose facsimile signature has
been placed upon such certificate, shall have ceased to be such officer before
such certificate is issued, it may nevertheless be issued by the Company with
the same effect as if such officer had not ceased to hold such office at the
date of its issue.

         SECTION 2. TRANSFER OF SHARES. The shares of stock of the Company
shall be transferable on the books of the Company by the holders thereof in
person or by duly authorized attorney, upon surrender and cancellation of
certificates for a like number of shares, with duly executed assignment and
power of transfer endorsed thereon or attached thereto, and with such proof of
the authenticity of the signatures as the Company or its agents may reasonably
require.

<PAGE>   9

         SECTION 3. LOST, STOLEN OR DESTROYED CERTIFICATES. No certificate of
stock claimed to have been lost, destroyed or stolen shall be replaced by the
Company with a new certificate of stock until the holder thereof has produced
evidence of such loss, destruction or theft, and has furnished indemnification
to the Company and its agents to such extent and in such manner as the proper
officers or the Board of Directors may from time to time prescribe.

                                 ARTICLE VII

         SECTION 1. RECORDS.  The Company shall keep such books and records as

         SECTION 2. INSPECTION.  Shareholders of the Company shall have the
right to inspect the books and records of the Company as provided by the law
of the state of Virginia.

                                  ARTICLE X

                                 AMENDMENTS.

         The Board of Directors may amend or repeal the Company's Bylaws
except to the extent that (i) The Company's articles of incorporation or
Virginia state law reserves this power to the stockholders, or (ii) the
shareholders in adopting or amending particular bylaws provide expressly that
the board of directors may not amend or repeal that bylaw. The Company's
