in connection with performance guarantees related to erosion and sediment
control. The balance remaining outstanding at December 31, 1997 was $53,000,
which is the approximate maximum amount outstanding during the year. Virginia
Natural Gas also guarantees a worker's compensation self-insured surety bond in
favor of the Commonwealth of Virginia in the amount of $750,000.
 
CNG Transmission has obtained several letters of credit to provide security to
the Commonwealth of Pennsylvania for the company's obligation to plug and
reclaim gas wells as part of the process of abandonment of such property.
One-half of the cost of one letter of credit on which CNG Transmission has
liability, having a face amount of $3,000,000, is shared by two nonaffiliated
pipeline companies. The maximum balance on CNG Transmission's portion of all
letters of credit during 1997 was $8,250,000, with $8,000,000 remaining
outstanding as of December 31, 1997.
 
CNG Energy Services has obtained a letter of credit in favor of TransCanada
Pipeline to secure the payment of demand charges for pipeline capacity under
contract until 2005. The original amount of the letter of credit was $4,414,900,
but was reduced on November 11, 1997 to $3,611,395.
 
CNG Retail has obtained a letter of credit in the amount of $120,000 in favor of
Columbia Gas of Pennsylvania to participate in that company's pilot program. The
term of the letter of credit is from November 1, 1997 to October 31, 1998.
 
The Company has issued guarantees to the states of Pennsylvania, Virginia and
West Virginia to maintain worker's compensation self-insured status for CNG
Transmission, Virginia Natural Gas and Hope Gas. Self-insured status means that
the subsidiary pays the worker's compensation claims directly instead of paying
into the state maintained fund. In recent years these states have revised their
worker's compensation programs and now require parent company guarantees--in
addition to surety bonds--for subsidiary companies to maintain self-insured
status.
 
All of the above transactions are exempt pursuant to Rule 45(b)(6).

(c) The Latin America Fund is an equity investment fund and as such has a
capital structure consisting of equity funds contributed by its partners.
Accordingly, there is no meaningful debt to equity ratio for the Latin America
Fund. The Latin America Fund had a net loss of $14,941 for the year ended
December 31, 1997.
 
(d) There are no service, sales or construction contracts between the Latin
America Fund, or any FUCOs in which the Latin America Fund has an interest, and
a CNG system company.
 
3. Information concerning the interests held by system companies in a FUCO
follows.
 
(a) Argentine FUCOs
 
In December 1997, CNG International acquired 12.5% ownership interests in two
gas utility holding companies, Sodigas Pampeana S.A. and Sodigas Sur S.A., and a
20% ownership interest in an electric utility holding company, Buenos Aires
Energy Company (BAECO), from CEI Citicorp Holdings S.A. in Argentina. The gas
utility holding companies have ownership interests in two gas distribution
companies, Camuzzi Gas Pampeana S.A. (Camuzzi Pampeana) and Camuzzi Gas del Sur
S.A. (Camuzzi del Sur), and BAECO has an ownership interest in an electric
distribution company, Empresa Distribuidora de Energia Atlantica S.A. (EDEA).
Camuzzi Pampeana, Camuzzi del Sur and EDEA are FUCOs.
 
Camuzzi Pampeana serves approximately 770,000 customers in Buenos Aires province
(but not in the city of Buenos Aires itself). Camuzzi del Sur serves
approximately 354,000 customers in Argentina to the south of Buenos Aires.
Camuzzi Pampeana and Camuzzi del Sur own, in the aggregate, approximately 3,600
miles of natural gas pipelines, 14,500 miles of natural gas distribution mains
and networks, and 540,000 service line connections. Camuzzi Pampeana and Camuzzi
del Sur together sell approximately 335 Bcf of natural gas per year.
 
EDEA serves approximately 398,000 electric customers in the province of Buenos
Aires, delivering about 1,800 gigawatt-hours a year. EDEA's electrical
distribution network consists of approximately 5,900 miles of high-, medium-,
and low-tension power lines with approximately 3,000 supporting substations
which transform energy to lower tensions for connection to many of EDEA's
customers.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Consolidated Natural Gas Company
 
In our opinion, the financial statements listed in the accompanying index on
page 24 present fairly, in all material respects, the consolidated financial
position of Consolidated Natural Gas Company and its subsidiaries at December
31, 1997, and the results of their operations and their cash flows for the year
then ended, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audit. We conducted our audit of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.
 
Our audit was made for the purpose of forming an opinion on the consolidated
financial statements taken as a whole. The consolidating information on pages 26
through 82 is presented for purposes of complying with the requirements of the
Public Utility Holding Company Act of 1935 rather than to present financial
position, results of operations, and cash flows of the individual companies.
Accordingly, we do not express an opinion on the financial position, results of
operations and cash flows of the individual companies. However, the
consolidating information on pages 26 through 82 has been subjected to the
auditing procedures applied in the audit of the consolidated financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the consolidated financial statements taken as a whole.

            except when the stockholder attends for the express purpose of
            objecting, at the beginning of the meeting, to the transaction of
            any business because the meeting is not lawfully called or convened.

     2.5    Adjourned Meetings. When a meeting is adjourned to another time or

<PAGE>   11



            alphabetical order, and showing the address of each stockholder and
            the number of shares registered in the name of each stockholder.
            Such list shall be open to the examination of any stockholder, for
            any purpose germane to the meeting, during ordinary business hours,
            for a period of at least ten days prior to the meeting, either at a
            place within the city where the meeting is to be held, which place
            shall be specified in the notice of the meeting, or, if not so
            specified, at the place where the meeting is to be held. The list

            stockholder who is present.

     2.7    Quorum. Except as otherwise required by statute, the presence at any
            meeting, in person or by proxy, of the holders of record of a
            majority of the shares then issued and outstanding and entitled to
            vote shall be necessary and sufficient to constitute a quorum for
            the transaction of business. In the absence of a quorum, the
            stockholders entitled to vote, present in person or by proxy, may
            adjourn the meeting from time to time until a quorum is present.

     2.8    Proxies. Each stockholder entitled to vote at a meeting of
            stockholders or to express consent or dissent to corporate action in
            writing without a meeting may authorize



<PAGE>   12



            another person or persons to act for him by proxy, but no such proxy
            shall be voted or acted upon after three years from its date, unless
            the proxy provides for a longer period. A duly executed proxy shall
            be irrevocable if it states that it is irrevocable and if, and only
            as long as, it is coupled with an interest sufficient in law to
            support an irrevocable power.

     2.9    Voting Rights. Except as otherwise provided by statute or by the
            Certificate of Incorporation, and subject to the provisions of
            Paragraph 7.5 of these Bylaws, each stockholder shall at every

            stockholders at which a quorum is present.

     2.11   Elections of Directors. Elections of directors need not be by
            written ballot.

     2.12   Consent of Stockholders in Lieu of Meeting. Any action required or
            permitted to be taken at any annual or special meeting of
            stockholders may be taken without a meeting, 



<PAGE>   13



            without prior notice and without a vote, if consent in writing,
            setting forth the action so taken, is signed by the holders of
            outstanding stock having not less than the minimum number of votes
            that would be necessary to authorize or take such action at a
            meeting at which all shares entitled to vote thereon were present
            and voted.

            Directors shall be held without notice immediately after, and at the

            Delaware, as shall be determined by the

            majority of the directors present at the time and place of any
            meeting may adjourn such meeting from time to time until a quorum be
            present.

                stockholders, (ii) for acts or omissions not in good faith or
                which involves intentional misconduct or a knowing violation of

                Law, or (iv) for any transaction from which the director derived
                an improper personal benefit.

            (b) To the full extent permitted by law, 



<PAGE>   17



                all directors of the Corporation shall be afforded any exemption
                from liability or limitation of liability permitted by any

                Corporation Law of the State of Delaware.

            (c) Any repeal or modification of either or both of the foregoing
                paragraphs by the stockholders of the Corporation shall not

                liability or other right of a director of the Corporation with

            President and the Board of Directors, whenever requested, an account
            of all his transactions as Treasurer and of the financial condition
            of the Corporation. He shall, in general, perform all duties and
            have all powers incident to the office of Treasurer and shall
            perform such other duties and have such other powers as may from
            time to time be assigned to him by these Bylaws, by the Board of
            Directors or by the President. The Assistant Treasurers, in the
            order determined by the Board, shall, in the absence of the
            Treasurer, perform the duties and exercise the powers of the
            Treasurer. Any Assistant Treasurer shall perform such other duties
            and have such other powers as the Board may prescribe.

     6.1    Execution of Instruments Generally. All documents, instruments or
            writings of any nature shall be signed, executed, verified,

            endorsements, and all evidence of indebtedness of the Corporation
            whatsoever, shall be signed by such officer or officers or such

            of Directors from time to time may determine. Endorsements for
            deposit to the credit of the Corporation in any of its duly
            authorized depositories shall be made in such manner as the Board of
            Directors from time to time may determine.

     6.3    Proxies. Proxies to vote with respect to shares of stock of other
            corporations owned by or standing in the name of the Corporation may
            be executed and delivered from time to time on behalf of the

            Corporation by the President or a Vice President, and by the

            Assistant Secretary of the Corporation



<PAGE>   24



            certifying the number of shares owned by him in the Corporation. Any
            or all of the signatures on the certificate may be by a facsimile.
            In case any officer who has signed or whose facsimile signature has
            been placed upon a certificate shall have ceased to be such officer
            before such certificate is issued, it may be issued by the
            Corporation with the same effect as if he were such officer at the
            date of issue.

     7.2    Transfer of Stock. Shares of stock of the Corporation shall only be
            transferred on the books of the Corporation by the holder of record
            thereof or by his attorney duly authorized in writing, upon
            surrender to the Corporation of the certificates for such shares
            endorsed by the appropriate person or persons, with such evidence of
            the authenticity of such endorsement, transfer, authorization and
            other matters as the Corporation may reasonably require, and
            accompanied by all necessary stock transfer tax stamps. In that
            event it shall be the duty of the Corporation to issue a new
            certificate to the person entitled thereto, cancel the old
            certificate, and record the transaction on its books.

     7.3    Rights of Corporation with Respect to Registered Owners. Prior to
            the surrender to the Corporation of the certificates for shares of
            stock with a request to record the



<PAGE>   25



            transfer of such shares, the Corporation may treat the registered
            owner as the person entitled to receive dividends, to vote, to
            receive notifications, and otherwise to exercise all the rights and
            powers of an owner.

     7.4    Transfer Agents and Registrars. The Board of Directors may make such
            rules and regulations as it may deem expedient concerning the
            issuance and transfer of certificates for shares of the stock of the
            Corporation and may appoint transfer agents or registrars or both,
            and may require all certificates of stock to bear the signature of
            either or both. Nothing herein shall be construed to prohibit the
            Corporation from acting as its own transfer agent at any of its
            offices.

     7.5    Record Dates. In order that the Corporation may determine the
            stockholders entitled to notice of or to vote at any meeting of
            stockholders or any adjournment thereof, or to express consent to
            corporate action in writing without a meeting, or entitled to
            receive payment of any dividend or other distribution or allotment
            of any rights, or entitled to exercise any rights in respect of any
            change, conversion or exchange of stock or for the purpose of any
            other lawful action, the Board of Directors may fix, in advance, a
            record date, which shall not be more than sixty nor less than ten
            days before the date of such meeting, nor more than sixty days prior
            to any other



<PAGE>   26



            action. If no record date is fixed, the record date for determining
            stockholders entitled to notice of or to vote at a meeting of
            stockholders shall be at the close of business on the day next
            preceding the day on which notice is given, or, if notice is waived,
            at the close of business on the day next preceding the day on which
            the meeting is held. If no record date is fixed, the record date for
            determining stockholders entitled to express consent to corporate
            action in writing without a meeting, when no prior action by the
            Board of Directors is necessary, shall be the day on which the first
            written consent is expressed. The record date for determining
            stockholders for any other purpose shall be at the close of business
            on the day on which the Board of Directors adopts the resolution
            relating thereto. A determination of stockholders of record entitled
            to notice of or to vote at a meeting of stockholders shall apply to
            any adjournment of the meeting; provided, however, that the Board of
            Directors may fix a new record date for the adjourned meeting.

     7.6    Lost, Destroyed and Stolen Certificates. Where the owner of a
            certificate for shares claims that such certificate has been lost,
            destroyed or wrongfully taken, the Corporation shall issue a new
            certificate in place of the original



<PAGE>   27



            certificate if the owner (a) so requests before the Corporation has
            notice that the shares have been acquired by a bona fide purchaser;
            (b) files with the Corporation a sufficient indemnity bond; and (c)
            satisfies such other reasonable requirements, including evidence of
            such loss, destruction, or wrongful taking, as may be imposed by the
            Corporation.


     8.     DIVIDENDS

     8.1    Sources of Dividends. The directors of the Corporation, subject to
            any restrictions contained in the statutes and Certificate of
            Incorporation, may declare and pay dividends upon the shares of the
            capital stock of the Corporation either (a) out of its surplus as
            defined and computed in accordance with the General Corporation Law
            of Delaware, as amended from time to time, or (b) in case there
            shall be no such surplus, out of its net profits for the fiscal year
            in which the dividend is declared and/or preceding fiscal year.

     8.2    Reserves. Before the payment of any dividend, the directors of the
            Corporation may set apart out of any of the funds of the Corporation
            available for dividends a reserve or reserves for any proper
            purpose, and the directors may abolish any such reserve in the
            manner in which it was created.


<PAGE>   28



     8.3    Reliance on Corporate Records. A director shall be fully protected
            in relying in good faith upon the books of account of the
            Corporation or statements prepared by any of its officials or by
            independent public accountants as to the value and amount of the
            assets, liabilities and net profits of the Corporation, or any other
            facts pertinent to the existence and amount of surplus or other
            funds from which dividends might properly be declared and paid, or
            with which the Corporation's stock might properly be redeemed or
            purchased.

     8.4    Manner of Payment. Dividends may be paid in cash, in property, or in
            shares of the capital stock of the Corporation at par.


     9.     GENERAL PROVISIONS

     9.1    Waiver of Notice. Whenever notice is required to be given under any
            provision of the statutes or of the Certificate of Incorporation or
            Bylaws, a written waiver thereof, signed by the person entitled to
            notice, whether before or after the time stated therein, shall be
            deemed equivalent to notice. Attendance of a person at a meeting
            shall constitute a waiver of notice of that meeting, except where
            the person attends a meeting for the express purpose of objecting,
            at the beginning



<PAGE>   29



            of the meeting, to the transaction of any business because the
            meeting was not lawfully called or convened.

     9.2    Seal. The corporate seal, subject to alteration by the Board of
            Directors, shall be in the form of a circle and shall bear the name
            of the Corporation and the year of its incorporation and shall
            indicate its formation under the laws of the State of Delaware. Such
            seal may be used by causing it or a facsimile thereof to be
            impressed or affixed or in any other manner reproduced.

     9.3    Fiscal Year. The fiscal year shall be the calendar year except as
            otherwise provided by the Board of Directors.

     9.4    Indemnification.

            (a) The Corporation shall indemnify any person who was or is a party
                or is threatened to be made a party to any threatened, pending
                or completed action, suit or proceeding, whether civil,
                criminal, administrative or investigative (other than an action
                by or in the right of the Corporation) by reason of the fact
                that he is or was a director, officer, employee or agent of the
                Corporation, or is or was serving at the written request of the
                Corporation as a director, officer, employee or agent of another
                corporation, partnership, joint venture, trust or other
                enterprise, against expenses (including attorneys' fees),
                judgments, fines and amounts paid in settlement actually


<PAGE>   30



                and reasonably incurred by him in connection with such action,
                suit or proceeding if he acted in good faith and in a manner he
                reasonably believed to be in or not opposed to the best
                interests of the Corporation, and, with respect to any criminal
                action or proceeding, had no reasonable cause to believe his
                conduct was unlawful. The termination of any action, suit or
                proceeding by judgment, order, settlement, conviction, or upon a
                plea of nolo contendere or its equivalent, shall not, of itself,
                create a presumption that the person did not act in good faith
                and in a manner which he reasonably believed to be in or not
                opposed to the best interests of the Corporation, and, with
                respect to any criminal action or proceeding, had reasonable
                cause to believe that his conduct was unlawful.

            (b) The Corporation shall indemnify any person who was or is a party
                or is threatened to be made a party to any threatened, pending
                or completed action or suit by or in the right of the
                Corporation to procure a judgment in its favor by reason of the
                fact that he is or was a director, officer, employee or agent of
                the Corporation, or is or was serving at the written request of
                the Corporation as a director, officer, employee or agent of
                another corporation, partnership, joint venture, trust or other
                enterprise, against expenses (including



<PAGE>   31



                attorneys' fees) actually and reasonably incurred by him in
                connection with the defense or settlement of such action or suit
                if he acted in good faith and in a manner he reasonably believed
                to be in or not opposed to the best interests of the Corporation
                and except that no indemnification shall be made in respect of
                any claim, issue or matter as to which such person shall have
                been adjudged to be liable to the Corporation unless and only to
                the extent that the court of Chancery of the State of Delaware
                or the court in which such action or suit was brought shall
                determine upon application that, despite the adjudication of
                liability but in view of all the circumstances of the case, such
                person is fairly and reasonably entitled to indemnity for such
                expenses which the Court of Chancery of the State of Delaware or
                such other court shall deem proper.

            (c) To the extent that a director, officer, employee or agent of the
                Corporation has been successful on the merits or otherwise in
                defense of any action, suit or proceeding referred to in
                subparagraphs (a) and (b) of this Paragraph 9.4, or in defense
                of any claim, issue or matter therein, he shall be indemnified
                against expenses (including attorneys' fees) actually and
                reasonably incurred by him in connection therewith.

            (d) Any indemnification under subparagraphs (a) and (b) of this
                Paragraph 9.4 (unless ordered by a court) shall be



<PAGE>   32



                made by the Corporation only as authorized in the specific case
                upon a determination that indemnification of the director,
                officer, employee or agent is proper in the circumstances
                because he has met the applicable standard of conduct set forth
                therein. 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, suit or proceeding, or (2)
                if such a quorum is not obtainable, or, even if obtainable a
                quorum of disinterested directors so directs, by independent
                legal counsel in a written opinion, or (3) by the stockholders.

            (e) Expenses incurred in defending a civil or criminal action, suit
                or proceeding may be paid by the Corporation in advance of the
                final disposition of such action, suit or proceeding upon the
                receipt of an undertaking by or on behalf of the director,
                officer, employee or agent to repay such amount if it shall
                ultimately be determined that he is not entitled to be
                indemnified by the Corporation as authorized in this Paragraph
                9.4.

            (f) The indemnification and advancement of expenses provided by or
                granted pursuant to the other subparagraphs of this Paragraph
                9.4 shall not be deemed exclusive of any other rights to which
                those seeking indemnification or advancement of



<PAGE>   33



                expenses may be entitled under any statute, by-law, agreement,
                vote of stockholders or disinterested directors or otherwise,
                both as to action in his official capacity and as to action in
                another capacity while holding such office.

            (g) By action of its Board of Directors, notwithstanding any
                interest of the directors in the action, the Corporation may
                purchase and maintain insurance, in such amounts as of the Board
                of Directors deems appropriate, on behalf of any person who is
                or was a director, officer, employee or agent of the
                Corporation, or is or was serving at the written request of the
                Corporation as a director, officer, employee or agent of another
                corporation, partnership, joint venture, trust or other
                enterprise, against any liability asserted against him and
                incurred by him in any such capacity, or arising out of his
                status as such, whether or not the Corporation would have the
                power or would be required to indemnify him against such
                liability under the provisions of this Paragraph 9.4 of the
                General Corporation Law of the State of Delaware.

            (h) The indemnification and advancement of expenses provided by, or
                granted pursuant to, this Paragraph shall, unless otherwise
                provided when authorized or ratified, continue as to a person
                who has ceased to be a director, officer, employee or agent and
                shall inure to the benefit of the heirs, executors and 
                administrators of such a person.

constitute a quorum at all meetings of stockholders for the transaction of
business, except as otherwise provided by statute or the charter or these by

director, officer, employee, or agent of the Company, and is threatened to be or
is made a party to any threatened, pending, or completed action, suit, or
proceeding, whether civil, criminal, administrative, or investigative (other
than an action by or in the right of the Company) by reason of the fact that he
is or was a director, officer, employee, or agent of the Company, or is or was
serving at the request of the Company as a director, officer, employee, or agent
of another corporation, partnership, joint venture, trust, or other enterprise,
shall be indemnified against expenses (including attorneys' fees), judgments,
fines, and amounts paid in settlement actually and reasonably incurred by him in
connection with any such action, suit, or proceeding if he acted in good faith
and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to



<PAGE>   64



any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit, or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his conduct
was unlawful.

         16.02    Each person who at any time, is, or shall have been, a
director, officer, employee, or agent of the Company, and is threatened to be or
is made a party to any threatened, pending, or completed action or suit by or in
the right of the Company to procure a judgment in its favor by reason of the
fact that he is or was a director, officer, employee, or agent of the Company,
or is or was serving at the request of the Company as a director, officer,
employee, or agent of another corporation, partnership, joint venture, trust, or
other enterprise shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the Company
and except that no indemnification shall be made in respect of any claim, issue,
or matter as to which such person shall have been adjudged to be liable for
negligence or misconduct in the performance of his duty to the Company unless
and only to



<PAGE>   65



the extent that the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the court shall deem proper.

         16.03    To the extent that a director, officer, employee, or agent of
the Company has been successful on the merits or otherwise in defense of any
action, suit, or proceeding referred to in sections 15.01 and 15.02, or in
defense of any claim, issue, or matter therein, he shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection therewith.

         16.04    Any indemnification under sections 15.01 and 15.02 (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 circumstances because he has met
the applicable standard of conduct set forth in sections 15.01 and 15.02. Such
determination shall be made (1) by the board by a majority vote of a quorum
consisting of directors who were not parties to such action, suit, or
proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable a
quorum of disinterested directors so directs, by independent legal counsel in a
written opinion, or (3) by the stockholders.

         16.05    Expenses incurred in defending a civil or criminal action,
suit, or proceeding may be paid by the Company in advance of the final
disposition of such action, suit, or proceeding as


<PAGE>   66



authorized by the board in the specific case upon receipt of an undertaking by
or on behalf of the director, officer, employee, or agent to repay such amount
unless it shall ultimately be determined that he is entitled to be indemnified
by the Company as authorized in these bylaws.

         16.06    The rights of indemnification provided in this article shall
in no way be exclusive of any other rights or indemnification to which any such
director, officer, employee, or agent may be entitled, under any bylaw,
agreement, vote of stockholders or disinterested directors, or otherwise, both
as to action in his official capacity and as to action in another capacity while
holding such office, and shall continue as to a person who has ceased to be a
director, officer, employee, or agent and shall inure to the benefit of the
heirs, executors and administrators of such person.

         16.07    The Company shall have power to purchase and maintain
insurance on behalf of any person who is or was a director, officer, employee,
or agent of the Company, or is or was serving at the request of the Company as a
director, officer, employee, or agent of another corporation, partnership, joint
venture, trust, or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the Company would have the power to indemnify him against such
liability under the provisions of this article.

         17.01    The shares of the Company shall be represented by numbered

president or a vice president and the secretary, an assistant secretary, the
treasurer, or assistant treasurer. The seal of the Company or a facsimile
thereof may be affixed to each certificate.

         17.02    The signatures of the officers of the Company upon a
certificate of stock may be facsimiles.

         17.03    In the event an officer who has signed or whose facsimile
signature has been placed upon a certificate shall have ceased to be such
officer before such certificate shall have been issued, the certificate may be
issued with the same effect as if he were such officer at the date of the
certificate's issue.


         18.      TRANSFERS OF STOCK

         18.01    Upon surrender to the Company or the transfer agent of a
certificate of stock, duly endorsed or accompanied by sufficient evidence of
succession, assignment, or authority to transfer, a new certificate shall be
issued to the person entitled thereto. The old certificate shall be canceled,
and the transaction shall be recorded on the books of the Company.


         19.      LOST OR DESTROYED CERTIFICATES

         19.01    The board may direct a new certificate to be issued in place
of any certificate theretofore issued by the Company and alleged to have been
lost or destroyed. Upon authorizing such issue of a new certificate, the board
may prescribe such terms and conditions as it deems expedient to protect the
Company.

         21.      REGISTERED STOCKHOLDERS

         21.01    The Company shall be entitled to treat the holder of record
of any share of stock as the holder in fact thereof and, accordingly, shall not
be bound to recognize any equitable or other claim to or interest in such share
on the part of any other person, whether or not the Company shall have express
or other notice thereof, except as otherwise provided by the laws of West
Virginia.


         22.      DIVIDENDS

REPORT OF INDEPENDENT ACCOUNTANTS

To the Partners of
Iroquois Gas Transmission System, L.P.:

We have audited the accompanying consolidated balance sheets of Iroquois Gas
Transmission System, L.P. and Subsidiaries as of December 31, 1997 and 1996, and
the related consolidated statements of income, changes in partners' equity and
cash flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. 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 audits provide a reasonable basis for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Iroquois Gas Transmission System, L.P. and Subsidiaries as of December 31, 1997
and 1996, and the consolidated results of their operations and their cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1. DESCRIPTION OF PARTNERSHIP:

Iroquois Gas Transmission System, L.P., ("Iroquois" or "Company") is a Delaware
limited partnership formed for the purpose of constructing, owning and operating
a natural gas transmission pipeline from the Canada-United States border near
Waddington, N.Y., to South Commack, Long Island, N.Y. In accordance with the
limited partnership agreement, the Partnership shall continue in existence until
October 31, 2089, and from year to year thereafter, until the Partners elect to
dissolve the Partnership and terminate the limited partnership agreement.

     The Partners consist of TransCanada Iroquois Ltd. (29.0%), North East
Transmission Co. (19.4%), CNG Iroquois, Inc. (16.0%), ANR Iroquois, Inc. (9.4%),
ANR New England Pipeline Co. (6.6%), ALENCO Iroquois Pipelines, Inc. (6.0%),
JMC-Iroquois, Inc. (4.93%), TEN Transmission Company (4.87%), NJNR Pipeline
Company (2.8%), and LILCO Energy Systems, Inc. (1.0%). In April 1996, Housatonic
Corporation and the New York Power Authority sold their partnership interest to
North East Transmission Co., TEN Transmission Company and JMC-Iroquois, Inc.,
whose interests were increased by 8%, 2.47% and 2.13%, respectively. In July
1996, ANR Iroquois, Inc. acquired all of the capital stock of Tennessee/New
England Pipeline Company and changed the acquired company's name to ANR New
England Pipeline Company. CNG Iroquois, Inc. purchased 50% of the partnership
interest held by ANR New England Pipeline Company, thereby increasing its
partnership share by 6.6% to 16%. In total, ANR's partnership share has also
increased to 16%. The Iroquois Pipeline Operating Company, a wholly-owned
subsidiary, is the administrative operator of the pipeline.

     Income and expenses are allocated to the Partners and credited to their
respective equity accounts in accordance with the partnership agreements and
their respective percentage interests.

     Distributions to Partners are made concurrently to all Partners in
proportion to their respective partnership interests. Total cash distributions
of $55.0 million and $40.0 million were made during 1997 and 1996, respectively.


2. SUMMARY OF SIGNIFICANT
   ACCOUNTING POLICIES:

BASIS OF PRESENTATION

The financial statements of the Company are prepared in accordance with
generally accepted accounting principles and with accounting for regulated
public utilities prescribed by the Federal Energy Regulatory Commission
("FERC"). Generally accepted accounting principles for regulated entities allow
the Company to give accounting recognition to the actions of regulatory
authorities in accordance with the provisions of Statement of Financial
Accounting Standards ("SFAS") No. 71, "Accounting for the Effects of Certain
Types of Regulation." In accordance with SFAS No. 71, the Company has deferred
recognition of costs (a regulatory asset) or has recognized obligations (a
regulatory liability) if it is probable that such costs will be recovered or
obligation relieved in the future through the rate-making process.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and
Iroquois Pipeline Operating Company, a wholly-owned subsidiary. Intercompany
transactions have been eliminated in consolidation.

CASH AND TEMPORARY CASH INVESTMENTS

Iroquois considers all highly liquid temporary cash investments purchased with
an original maturity date of three months or less to be cash equivalents. Cash
and temporary cash investments of $26.4 million, consisting primarily of low
risk mutual funds, are carried at cost, which approximates market. At December
31, 1997 and 1996, $10.6 million and $11.0 million, respectively, of cash and
temporary cash investments were held to satisfy the terms of the Loan Agreement
(refer to Note 3).

NATURAL GAS PLANT IN SERVICE

Natural gas plant in service is carried at original cost. The majority of the
natural gas plant in service is categorized as natural gas transmission plant
which was depreciated over 20 years on a straight line basis from the in-service
date through January 31, 1995. Commencing February 1, 1995, transmission plant
is depreciated over 25 years on a straight-line basis as a result of the rate
case settlement. The general plant is depreciated on a straight-line basis over
various useful lives averaging five years.

CONSTRUCTION WORK IN PROGRESS

At December 31, 1997, construction work in progress included preliminary
construction costs relating to the proposed Athens compressor station and
on-going minor capital projects.

ALLOWANCE FOR FUNDS
USED DURING CONSTRUCTION

The allowance for funds used during construction ("AFUDC") represents the cost
of funds used to finance natural gas transmission plant under construction. The
AFUDC rate includes a component for borrowed funds as well as equity. The AFUDC
is capitalized as an element of natural gas plant in service.

PROVISION FOR TAXES

The payment of income taxes is the responsibility of the Partners and such taxes
are not normally reflected in the financial statements of partnerships.
Iroquois' approved rates, however, include an allowance for taxes (calculated as
if it were a corporation) and the FERC requires Iroquois to record such taxes in
the Partnership records to reflect the taxes payable by the Partners as a result
of Iroquois' operations. These taxes are recorded without regard as to whether
each Partner can utilize its share of the Iroquois tax deductions. Iroquois'
rate base, for rate-making purposes, is reduced by the amount equivalent to
accumulated deferred income taxes in calculating the required return.

     Effective January 1, 1993, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 109, "Accounting for Income Taxes." Under SFAS
No. 109, deferred taxes are provided based upon, among other factors, enacted
tax rates which would apply in the period that the taxes become payable, and by
adjusting deferred tax assets or liabilities for known changes in future tax
rates. SFAS No. 109 requires recognition of a deferred income tax liability for
the equity component of AFUDC.

ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

RECLASSIFICATIONS

Certain prior year amounts have been reclassified to conform with current year
classifications.

3. FINANCING:

On June 11, 1991, Iroquois entered into a loan agreement which provided a loan
facility totaling $522.6 million to be amortized over a 14-year period
commencing November 1, 1992.

     On August 30, 1992, the total amount of the loan became non-recourse to the
Partners. However, the Partners' equity interest remained pledged until December
7, 1993, at which time the required conditions were met and the liens were
extinguished.

     During 1993, Iroquois entered into Expansion Loan Agreement No. 1 in the
amount of $17.6 million to construct the Wright Compressor Station. The
expansion loan conditions are substantially the same as those of the base loan
and are non-recourse with respect to the Partners. The loan will mature in
November 2007.

     During 1995, Iroquois entered into Expansion Loan Agreement No. 2 in the
amount of $13.4 million to finance the Croghan Compressor Station. This loan is
subject to similar provisions as the above noted loans. The loan will mature in
November 2008.

     As of December 31, 1997, Iroquois was party to interest rate swap
transactions for aggregate notional principal amounts of $550.7 million. The
interest rate swaps relating to the original loan and Expansion Loan No. 1 are
$537.6 million which are being amortized over 14 years in accordance with the
principal repayment schedule provided in the Loan Agreement. The interest rate
and margin over the term of the swaps average 7.615% and 1.159%, respectively.
The interest rate swap relating to Expansion Loan No. 2 is $13.2 million with an
average interest rate and margin of 6.0% and 1.066%, respectively. The interest
rate swap for Expansion Loan No. 2 expires November 2, 1998 at which time the
interest rate, unless a new interest rate swap is undertaken, will be based upon
daily LIBOR plus an average margin of 1.153% over the term of the loan. The
Original Loan Agreement requires that at least 50% of the original debt is
hedged by interest rate swaps. The fair value of interest rate swaps is the
estimated amount that Iroquois would receive or pay to terminate the swap
agreements at the reporting date, taking into account current interest rates and
current credit worthiness of the swap counterparties. The fair value of the
interest rate swaps were ($29.1) million and ($23.1) million at December 31,
1997 and 1996, respectively.

     Iroquois is subject to risk from non-performance of the counterparties of
the swap agreements. In the event of non-performance, the Company would be
required to pay interest subject to the original terms of the loan agreement.
This risk is substantially mitigated by the fact that the counterparties are
large, highly-rated financial institutions. At December 31, 1997 the largest
single swap agreement subject to exposure was $10.7 million.

     At December 31, 1997, the outstanding principal was $367.9 million on the
base loan, $13.9 million on Expansion Loan Agreement No. 1 and $12.3 million on
Expansion Loan No. 2 for total long-term debt of $394.1 million. The combined
schedule of repayments is as follows (in millions):

<TABLE>
<CAPTION>
         Year             Scheduled Repayment
         ----             ------------------- 
         <S>                    <C>
         1998                   $ 28.7
         1999                   $ 28.7
         2000                   $ 28.8
         2001                   $ 26.7
         2002                   $ 26.7
         Thereafter             $254.4
</TABLE>


The loan agreements are collateralized by all the assets of the Partnership and
subject Iroquois to certain restrictions and covenants related to, among other
things, indebtedness, investments, certain expenditures, financial ratios, and
limitations on distributions to Partners. At December 31, 1997, the Company had
an outstanding letter of credit in the amount of $31.3 million, which is
guaranteed by the Partners.

     The Company has an unsecured line of credit which permits borrowings up to
a maximum of $10 million at a rate equal to the lower of the lenders' alternate
base rate or one, two or three month LIBOR plus 3/8% per annum. This facility is
reviewed on an annual basis with the current agreement expiring in May 1998. The
line of credit contains a subjective acceleration clause as its most restrictive
covenant.

4. CONCENTRATIONS OF CREDIT RISK:

Iroquois' cash and temporary cash investments and trade accounts receivable
represent concentrations of credit risk. Management believes that the credit
risk associated with cash and temporary cash investments is mitigated by its
practice of limiting its investments to low risk mutual funds, rated Aaa by
Moody's Investor Services and AAA by Standard and Poor's, and its cash deposits
to large, highly-rated financial institutions. Management also believes that the
credit risk associated with trade accounts receivable is mitigated by the
restrictive terms of the FERC gas tariff which requires customers to pay for
service within 20 days after the end of the month of service delivery.

5. GAS TRANSPORTATION CONTRACTS:

As of December 31, 1997, Iroquois was providing multi-year firm reserved
transportation service to 32 shippers of 876.8 MMcf/d of natural gas which
breaks down as follows:

<TABLE>
<CAPTION>

         16-20                            302.2
                                          -----
         Total                            876.8
                                          =====
</TABLE>


The long-term firm service gas transportation contracts expire between 
November 1, 2011 and October 1, 2014.

6. COMMITMENTS AND CONTINGENCIES:

REGULATORY PROCEEDINGS

On November 29, 1996, Iroquois submitted a general rate change application to
the Federal Energy Regulatory Commission ("FERC" or "Commission") in Docket No.
RP97-126-000. That rate change application represented a reduction in Iroquois'
test-period revenues of approximately $4.6 million compared to Iroquois'
then-effective rates. In an order issued on December 31, 1996 ("Suspension
Order"), the Commission accepted and suspended the rates, permitted them to
become effective (with one exception noted below) on January 1, 1997, and
established a hearing. The order also required the Presiding Administrative Law
Judge to issue a decision in this proceeding by December 31, 1997. Pursuant to
that Suspension Order, the Presiding Administrative Law Judge conducted a
hearing on all issues raised by Iroquois' filing, which was concluded on August
28, 1997.

     Following the submission of initial, reply and supplemental briefs, the
Presiding Administrative Law Judge issued his Initial Decision on December 31,
1997. While the Presiding Administrative Law Judge ruled in Iroquois' favor on
certain issues, on others (such as reducing the depreciation rate from 4% to
2.77%; reducing Iroquois' equity ratio from 35% to



<PAGE>   9


27%; and reducing the authorized rate of return from the currently effective 15%
to 10.97%) he ruled against Iroquois. That Initial Decision, if adopted by the
Commission without changes, would result in an additional significant reduction
in Iroquois' revenues on a prospective basis. Iroquois filed a brief on
exceptions vigorously opposing certain aspects of the Administrative Law Judge's
findings on January 30, 1998; briefs opposing exceptions were submitted to the
Commission on February 27, 1998. The Commission's order establishing Iroquois'
future rates is not expected to be issued until mid-to-late 1998. Iroquois'
existing rates will continue to apply until such time.

     The Suspension Order granted summary disposition on one issue: as a result
of the Commission's December 20 Opinion in Docket No. RP94-72 (discussed below),
Iroquois was ordered to remove approximately $11.7 million in plant and
associated costs from its proposed rate base. This results in an additional
reduction in Iroquois' test-period revenues of approximately $2.0 million from
those set forth in the filing. On January 15, 1997, Iroquois submitted its
filing in compliance with the Suspension Order. This compliance filing was
accepted by the Commission on February 12, 1997. Iroquois also sought rehearing
(on January 30, 1997) of the Suspension Order; this was denied by the Commission
by an order issued August 5, 1997. On September 3, 1997, Iroquois filed a
Petition for Review of the Commission's Suspension and August 5 Orders in the
United States Court of Appeals for the District of Columbia Circuit, docketed as
D.C. Cir. No. 97-1533, which was consolidated with D.C. Cir. No. 97-1276
(discussed below).

     The Commission, on June 19, 1995, approved a Stipulation and Consent
Agreement in Iroquois' prior rate proceeding in Docket No. RP94-72, which
resolved all issues except for the accounting and recovery of legal defense
costs incurred in connection with certain criminal and civil investigations into
the initial construction of the Iroquois facility. A hearing was held on this
reserved issue on April 5, 1995. On July 19, 1995, the Presiding Administrative
Law Judge issued an Initial Decision which would have permitted Iroquois to
capitalize those legal defense costs and recover $4.1 million (the dollar amount
of such costs which Iroquois filed to recover in Docket No. RP94-72) from its
customers. Various participants, including the Commission Staff, filed
exceptions to the Initial Decision with the Commission (which were opposed by
Iroquois on September 7, 1995). On December 20, 1996, the Commission issued an
order reversing the Initial Decision and disallowing recovery of the legal
defense costs at issue. Iroquois filed a request for rehearing of the
Commission's December 20 Order on January 21, 1997. By Order issued March 3,
1997, the Commission denied rehearing. Iroquois filed a petition for review of
the December 20 and March 3 Orders in the United States Court of Appeals for the
District of Columbia Circuit on April 18, 1997 in D.C. Cir. No. 97-1276.
Iroquois submitted its initial brief in that case (and the consolidated D.C.
Cir. No. 97-1533) on January 7, 1998; briefs of the Commission and intervenors
supporting the Commission were filed in February 1998, and Iroquois' reply brief
was filed on March 9, 1998. Oral argument will be held on May 14, 1998, with the
court's decision being issued sometime thereafter.

LEGAL PROCEEDINGS-OTHER

Iroquois is party to various other legal actions incident to its business;
however, management believes that no material losses will result from such
proceedings.

LEASES

Iroquois leases its office space under operating lease arrangements. The leases
expire at various dates through 2003 and are renewable at Iroquois' option.
Iroquois also leases a right-of-way easement on Long Island, New York, from the
Long Island Lighting Company ("LILCO"), a general partner, which requires annual
payments escalating 5% a year over the 39-year term of the lease. In addition,
Iroquois leases various equipment under non-cancelable operating leases. During
the years ended December 31, 1997, and 1996, Iroquois made payments of $1.0
million and $0.9 million respectively, under operating leases which were
recorded as rental expense. Future minimum rental payments under operating lease
arrangements are as follows (millions of dollars):

7. INCOME TAXES:

Deferred income taxes which are the result of operations will become the
obligation of the Partners when the temporary differences related to those items
reverse. The Company recognizes a decrease in the Amounts Equivalent to Deferred
Income Taxes account for these amounts and records a corresponding increase to
Partners' equity. Deferred income taxes with respect to the equity component of
AFUDC remain on the accounts of the Partnership until the related deferred
regulatory asset is recognized.

     Total income tax expense includes the following components (thousands of
dollars):

For the years ended December 31, 1997 and 1996, the effective tax rate differs
from the Federal statutory rate due principally to the impact of state taxes,
and the prior year non-deductible portion of the provision for the Federal
investigations.

9. RETIREMENT BENEFIT PLANS:

During 1997, the Company established a non-contributory retirement plan ("Plan")
covering substantially all employees. Pension benefits are based on years of
credited service and employees' career earnings, as defined in the Plan. The
Company's funding policy is to contribute, annually, an amount at least equal to
that which will satisfy the minimum funding requirements of the Employee
Retirement Income Security Act plus such additional amounts, if any, as the
Company may determine to be appropriate from time to time.

     During 1997, the Company also adopted an excess benefit plan (EBP) that
provides retirement benefits to executive officers and other key management
staff. The EBP recognizes total compensation and service that would otherwise be
disregarded due to Internal Revenue Code limitations on compensation in
determining benefits under the regular retirement plan. The EBP is not funded
and benefits are paid when due from general corporate assets.

     The following table represents the two plans' combined funded status and
amounts included in the balance sheet at December 31, 1997 (thousands of
dollars):

                    Report of Independent Public Accountants




To the Partners of
Lakewood Cogeneration, L.P.:

We have audited the accompanying balance sheets of Lakewood Cogeneration, L.P.
(a Delaware Limited Partnership) as of December 31, 1997 and 1996, and the
related statements of income, changes in partners' equity and cash flows for the
years then ended. These financial statements are the responsibility of the
Partnership's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Lakewood Cogeneration, L.P.
as of December 31, 1997 and 1996, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.

LAKEWOOD COGENERATION, L.P.

NOTES TO THE FINANCIAL STATEMENTS
YEARS ENDED DECEMBER 31, 1997 AND 1996
- --------------------------------------------------------------------------------


1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

General - Lakewood Cogeneration, L.P. (the Partnership) was formed to develop,
construct, own and operate a 237 megawatt power production facility (the
Facility) located in Lakewood, New Jersey. The Facility generates electric power
for sale to General Public Utilities (GPU), formerly Jersey Central Power &
Light, primarily by burning natural gas with oil as a backup fuel. Although
originally a Qualifying Facility under Federal laws, in September 1993 the
Federal Energy Regulatory Commission approved the Partnership's application for
Exempt Wholesale Generator (EWG) status. Commercial operations commenced in
November 1994.



Ownership interests of the partners are:


General Partners
- ----------------

HCE Lakewood, Inc. (HCE)                        1%
CNG Lakewood, Inc. (CNG)                        1%

Limited Partners
- ----------------

Hydra-Co Enterprises, Inc. (HYDRA-CO)           44%
CNG Power Company (CNG Power)                   34%
TPC Lakewood, Inc. (TPC)                        20%


HCE is a wholly owned affiliate of HYDRA-CO, which is a wholly owned subsidiary
of CMS Generation Co. (CMS). CNG is a wholly owned subsidiary of CNG Power,
which is a wholly owned subsidiary of CNG Energy Services Corporation (ESC).
Profits, losses and cash distributions are allocated among the partners in
proportion to their respective ownership interest.

Basis of Presentation - The financial statements are prepared in conformity with
generally accepted accounting principles and include the use of management
estimates.

Cash Equivalents - The Partnership considers all highly liquid investments
purchased within three months of their maturity to be cash equivalents.

Restricted Cash - Restricted cash represents amounts consisting primarily of
disbursement, major maintenance, and debt service, bank litigation, and
punchlist and warranty funds which are restricted as to their use.

Plant and Equipment - Plant and equipment are stated at cost. Depreciation is
generally provided over estimated useful lives ranging from three to thirty
years. The composite depreciation rate for the Facility in 1997 and 1996 was
3.3%.

Inventories - Fuel inventories are stated at cost using the first in first out
method.

Deferred Charges - Costs associated with the formation of the Partnership
aggregating approximately $5,419,000 were deferred and are being amortized using
the straight-line method over a five-year period commencing with the commercial
operation of the Facility. Amortization expense of such costs amounted to
approximately $1,084,000 and $1,108,000 in 1997 and 1996, respectively.

Costs incurred in negotiating and securing the construction and term financing
amounted to $4,103,000. These costs 


                                       6
<PAGE>   8

have been deferred and are being amortized using the effective interest method
over the term of the related debt. Amortization of such costs amounted to
approximately $383,000 and $294,000 in 1997 and 1996, respectively.

Income Taxes - The Partnership has no liability for income taxes. Income is
taxed to the partners based on their allocated share of taxable income (loss).
Therefore, no provision or liability for income taxes has been included in the
accompanying financial statements.

Fair Value of Financial Instruments - The carrying amount of cash, cash
equivalents and restricted cash approximates fair value because of the short
maturities of these instruments. The Partnership's notes payable and
short-term debt approximate fair value because their interest rates are based
upon variable reference rates. The fair value of the Partnership's interest
rate swaps (used for hedging purposes) is the estimated amount the Partnership
would have to pay to terminate the swap agreements, taking into account current
interest rates and the current creditworthiness of the swap counterparties. The
estimated termination cost associated with the interest rate swaps at December
31, 1997 and 1996 is approximately $3,347,000 and $511,000, respectively.

Reclassifications - Certain reclassifications have been made to prior years'
statements to conform with the 1997 presentation.


2. LONG-TERM DEBT

A consortium of banks had made available for construction Tranche A and Tranche
B Bank Loans in the amount of $136,000,000 and $51,000,000, respectively. Total
Tranche A Bank Loans in the amount of $136,000,000 were converted into the
Continuing Bank Term Loans (the Term Loan(s)) on June 8, 1995 (the Conversion
Date). Tranche B Loans were unused. In order to convert the construction loans
to term loans, each of the partners contributed cash or converted their then
outstanding subordinated loans to equity. The Term Loans are being repaid in
semi-annual installments over a fourteen year period which commenced June 30,
1995. The Partnership may select the interest rate for the Term Loans from three
alternatives: a Base Rate option, a CD Rate option and a LIBOR Rate option. Each
of these rates is equivalent to the corresponding Mellon Bank interest rate
option plus a credit spread which varies depending on the type of Term Loan, and
the interest period and option chosen. As of December 31, 1997 and 1996, 
$123,760,000 and $128,520,000, respectively, was outstanding under the Term 
Loans.

The Partnership also has a $2,000,000 Working Capital Loan available. The
Partnership pays a standby fee on the average daily unused portion of the
Working Capital Loan. Fees totaled $8,600 and $7,700 in 1997 and 1996,
respectively. This loan commitment matures on the fifth anniversary of the
Conversion Date with one year extensions through the final maturity date of the
Term Loans.

The Partnership has agreed to pay an Administrative Agent's Fee to Mellon of
$75,000 per year. The Partnership paid fees of $75,000 in 1997 and 1996,
respectively.

The Partnership has obtained a $75,000,000 institutional loan from John Hancock
Mutual Life Insurance Company (the Institutional Loan). Outstanding balances as
of December 31, 1997 and 1996 were $73,125,001 and S73,875,001, respectively.
The Institutional Loan is being repaid in semi-annual installments over an
eighteen and one-half year period which began June 30, 1995 and bears a fixed
interest rate of 10.66 percent.


                                       7
<PAGE>   9

Obligations under the Term Loans and Institutional Loan mature as follows:



Year                  Term Loans                 Institutional Loan
1998                $  6,120,000                   $   750,000
1999                   6,800,000                       750,000
2000                   7,480,000                       750,000
2001                   8,840,000                       750,000
2002                  10,200,000                       750,000
Thereafter            84,320,000                    69,375,001
                    ------------                   -----------
Total               $123,760,000                   $73,125,001


The Partnership has entered into interest rate swap agreements to reduce the
impact of changes in interest rates on the Term Loans. At December 31, 1997 and
1996, the Partnership had two interest rate swap agreements outstanding with
total notional principal amounts of $113,750,000 and $120,000,000, respectively.
Those agreements effectively change the Partnership's interest rate exposure on
a portion of the Term Loans through 2008 to an average all-in borrowing cost of
6.68 percent. The Partnership is exposed to credit loss in the event of
nonperformance by the other parties to the interest rate swap agreements.
However, the Partnership does not anticipate nonperformance by the
counterparties who are affiliated with Mellon Bank and ABN-AMRO.


3. RELATED PARTY TRANSACTIONS

The Partnership has entered into an Operation and Maintenance Agreement (the
O&M Agreement) with CMS Generation Operating Company II, Lakewood Division
(CMSG II), a wholly-owned subsidiary of HYDRA-CO. The O&M Agreement expires on
the twenty-first anniversary of the commercial operations date and may be
renewed annually thereafter. Under the terms of the O&M Agreement, CMSG II is
reimbursed for all direct costs incurred, receives an overhead fee of $200,000
and a base fee of $60 per hour multiplied by the number of hours the Facility is
actually dispatched. CMSG II can also earn a bonus if certain performance
factors are achieved. Fees and bonuses earned by CMSG II were $461,000 and
$473,000 in 1997 and 1996, respectively. CMSG II was also reimbursed for direct
costs incurred on behalf of the Partnership of $3,675,000 and $3,663,000 in
1997 and 1996, respectively.

The Partnership has entered into a Fuel Management Agreement (the FMA) with
ESC, to develop, implement and administer a comprehensive fuel supply and
transportation strategy. The FMA terminates December 31, 2001 and will be
automatically renewed for additional one-year terms unless terminated by either
party. ESC was reimbursed for fees and direct costs incurred on behalf of the
Partnership of $14,367,000 and $13,109,000 in 1997 and 1996, respectively.

<PAGE>   10

the Warranty Period, as defined. Total project management fees charged by LPMI
for project management services in 1997 and 1996 were $12,000 and $156,000,
respectively, and are included as a component of property, plant and equipment.

Under the terms of the Partnership Agreement and the loan agreements, certain
construction cost underruns have been paid to the general partners. As of
December 31, 1997 and 1996, $15,574,000 and $15,258,000, respectively, have been
paid to the partners for these cost underruns, including $316,000 and $2,000,000
during 1997 and 1996, respectively. These cost underrun distributions were
capitalized in the accompanying financial statements.


4. COMMITMENTS AND CONTINGENCIES

Electricity from the Facility is sold under a 20-year Power Purchase Agreement
(the PPA) whereby GPU will purchase the contract capacity, as defined, at
specified rates under a dispatchable arrangement. The PPA expires twenty years
from November 8, 1994 and may be extended for successive periods of five years.
The Facility also generates steam for sale to three customers under a 5-year
agreement commencing in 1996.

The Partnership entered into an Amended and Restated Performance Construction
Contract (the EPC Contract) with CRS Sirrine Engineers, Inc. (CRSS) for a total
contract price of $151,900,000. In accordance with the EPC Contract, the
Partnership withheld 10% of the amounts payable to CRSS as retainage until
Substantial Completion, as defined, was achieved. The EPC Contract called for
the Facility to be substantially complete by September 1, 1994 at which time
certain performance tests were required to be met. The EPC Contract also
provided for CRSS to pay certain liquidated damages to the extent that these
performance tests or certain other milestones were not met by September 1, 1994.

In February 1995, CRSS and the Partnership entered into a Settlement Agreement
whereby the date of Substantial Completion was designated November 9, 1994.
Furthermore, the balance of retainage held prior to the Settlement Agreement
($15,445,000) was reduced by $5,200,000 in full satisfaction of liquidated
damages. This amount has been recorded as a reduction to property, plant and
equipment in the accompanying balance sheets. The Settlement Agreement also
allowed the Partnership to hold from retainage, otherwise due and payable, an
amount of $3,000,000 as security for the performance of final punchlist items
and an amount of $2,000,000 in an interest bearing escrow account for a
specified amount of time as security for potential warranty claims. The
remaining retainage of $5,245,000 due to CRSS was paid in March 1995. CRSS has
indemnified the Partnership against any liabilities or costs incurred as a
result of any disputes between CRSS and its subcontractors and unconditionally
guaranteed the performance of warranty obligations of CRSS. At the Final
Completion Date (November 20, 1995), it was determined that punchlist items
valuing $511,688 remained to be completed. As such $1,488,312 plus $28,500 of
accrued interest was returned to CRSS. This escrow account was closed during
1996. At December 31, 1997 and 1996, $64,508 and $112,121 of retainage remains
due and payable to CRSS.

The Partnership entered into various agreements with New Jersey Natural Gas
Company (NJNG), whereby NJNG constructed natural gas pipelines interconnecting
the Facility with two interstate pipeline systems; the Partnership purchased
these pipeline assets for $6,850,000 which is included as a component of
property, plant and equipment. The Partnership pays NJNG an annual charge of
$2,616,000 in capacity reservation charges. This agreement expires in April 2014
and provides for early termination payments to NJNG under certain circumstances.
NJNG also has the right to repurchase the assets at the termination of the
agreement.

Currently the Facility has two steam customers. Each agreement has an initial
term of five years and can be automatically extended annually with agreement of
both parties for up to twenty years. The Partnership was required to construct
the steam distribution system to deliver steam to the customers and is included
as a component of property, plant, and equipment in the accompanying balance
sheets.

                                       9

Pursuant to an amended Agreement of Grant and Reservation with the Lakewood
Township Municipal Utilities Authority (LTMUA), the Partnership has agreed to
construct and maintain certain water facilities whose title will transfer to
LTMUA upon their completion. In addition, the Partnership has agreed to make
non-refundable contributions to LTMUA toward the construction, permitting, and
operation of wells needed to provide water to the Facility.

In October 1995, the Partnership entered into a Long Term Maintenance Agreement
with ABB Power Generation, Inc. (ABB) for its two combustion turbines. The
contract value of $16,051,000 is to be paid over a 61 month period. Contract
payments of $3,380,000 and $2,880,000 were paid to ABB in 1997 and 1996,
respectively.

The Partnership has entered into an Environmental Preservation Trust Fund
Agreement with the Township of Lakewood (the Township). On the financial closing
date, the Partnership paid the Township $2,000,000 for the creation of an
Environmental Preservation Trust Fund (the Fund) in order to insure that the
Partnership will promptly respond to cure any Facility related environmental
impacts. The Township has the right to receive all interest earned on amounts
invested in the Fund which terminates after twenty years when the $2,000,000
principal will be returned to the Partnership. This amount has been reflected as
a receivable from the Township in the accompanying balance sheets.

The Partnership has also entered into a Host Benefits Agreement with the
Township to make minimum annual payments in the amount of $600,000 or the
actual amount of real estate taxes assessed on the Facility, whichever is
greater. In September 1994, the Township assessed the Facility approximately 
$1,900,000 in annual property taxes, a level which the Partnership appealed. In
August 1996, a settlement agreement was reached providing for annual property
taxes of approximately $1,200,000. Cash payments in excess of the $1,200,000
made from 1994 though 1996 are to be credited against future payments through
1998. As of December 31, 1997 and 1996, the outstanding settlement amount which
the Partnership can deduct from future tax payments is approximately $801,000
and $1,900,000, respectively, and is reflected as prepaid expenses in the
accompanying balance sheet. In 1996, this settlement reduced administrative and
general expenses in the accompanying statement of income by $930,000.

In accordance with an agreement between the Partnership and the Ocean County
Prosecutor in Toms River, New Jersey, the Partnership has agreed to cooperate
with any ongoing investigation into certain activities surrounding the
development of the Facility and to perform community service in exchange for
acceptance by the Prosecutor's office of no admission of guilt by the
Partnership and certain of its affiliates. This agreement expired in August
1997.

Until the completion of all construction and warranty phases, the Partnership is
required to maintain a Punchlist and Warranty Escrow. Funds may be withdrawn to
pay construction costs with prior approval of both Mellon Bank and its
Independent Engineers. The excess funds of the Punchlist and Warranty Escrow not
used for construction items will be distributed to the partners as either a
management fee or a return of capital. As of December 31, 1997 the account has
been closed. As of December 31, 1996, the balance in the Punchlist and Warranty
Escrow was $361,232.

opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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 audits provide a reasonable basis for our opinion.

As explained in Note 2, the financial statements include securities valued at
$41,920,297 (97 percent of net assets) and $19,673,684 (94 percent of net
assets) as of December 31, 1997 and 1996, respectively, whose values have been
estimated by the Fund Manager in the absence of readily ascertainable market
values. However, because of the inherent uncertainty of valuation, those
estimated values may differ significantly from the values that would have been
used had a ready market for the securities existed, and the differences could be
material.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the Latin America Energy and
Electricity Fund I, L.P. as of December 31, 1997 and 1996, and the results of
its operations and its cash flows for the years then ended, in conformity with
accounting principles generally accepted in the United States.

                          THE LATIN AMERICA ENERGY AND
                            ELECTRICITY FUND I, L.P.


                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1997 AND 1996



1.  ORGANIZATION

The Latin America Energy and Electricity Fund I, L.P. (the "Fund"), a Cayman
Islands exempted limited partnership, was formed on July 17, 1995, and commenced
operations on October 31, 1995, pursuant to an amended and restated partnership
agreement (the "Partnership Agreement") as of that date. The Fund was organized
to invest in companies whose primary business is generating, transmitting and
distributing electric power in Latin or South America. The General Partner of
the Fund is FondElec General Partner, L.P. (the "General Partner"), a Cayman
Islands exempted limited partnership. The Fund shall terminate on October 31,
2003. Its term may be extended for an additional period of up to two years by
the General Partner with the approval of the investment committee, or it may be
terminated earlier under certain circumstances, as described in the Partnership
Agreement. The Fund is managed by FondElec Group, Inc. (the "Fund Manager").

The General Partner of the Fund, subject to certain conditions, has the power to
carry out any and all of the objectives and purposes of the Fund. The General
Partner must receive approval from the investment committee (consisting of
representatives of the strategic limited partners of the Fund) prior to taking
certain investment and administrative actions for the Fund.

2.  SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Investment Valuation

Unquoted securities are stated at their estimated fair value at December 31,
1997 and 1996, as determined by the Fund Manager.

Investment Transactions

The cost of securities sold is determined on the first-in, first-out basis.



<PAGE>   9
                                      -2-


Deferred Investment Costs

Expenses incurred in connection with the due diligence investigations of
potential investments and related costs incurred are capitalized and are
included in other assets on the accompanying balance sheets. Such costs are
either added to the cost of the investment when consummated or expensed when the
decision is made not to pursue the opportunity any further.

Foreign Currency Transactions

The functional currency of the Fund is the U.S. dollar. Assets and liabilities
denominated in foreign currencies, if any, are translated into U.S. dollar
equivalents using the prevailing year-end spot exchange rate with the resulting
gains and losses included in net unrealized gain on investment.

Organization Costs

Costs incurred in the organization of the Fund totaling $600,000 have been
capitalized and are being amortized on a straight-line basis over a period of
five years.

Income Taxes

No provision is made for United States federal income or excise taxes as the
Fund is organized in the Cayman Islands and does not operate in the United
States. Presently, there is no direct taxation in the Cayman Islands. As such,
interest, distributions and gains received by the Fund are free of all Cayman
Islands taxes.

3.  PARTNERS' CAPITAL

Capital Contributions

Cumulative capital contributions were $63,715,187 and $24,117,894 at December
31, 1997 and 1996, respectively. However, there was a $15,900,000 return of
capital for an unconsummated investment during 1997. Total capital commitments
of the partners were $60,303,030. The balance is payable upon call by the
General Partner. The Partnership Agreement provides each limited partner the
option not to participate in any specific investment. In such case, the required
contributions of the other limited partners for such investment shall be
proportionally increased.

Distributions

Distributions shall be made to the partners in proportion to the allocation of
investment proceeds no more than 60 days after the end of the fiscal quarter in
which such investment proceeds were received by the Fund.

On May 30, 1996, the Fund distributed $2,431 and $240,742 to the General Partner
and to the Limited Partners, respectively. The distribution was comprised of
interest income and dividends received from the Fund's investment in
Ontario-Quinta A.V.V. ("Ontario-Quinta") (Note 4).


<PAGE>   10
                                      -3-


During 1997, the distributions to General Partner and Limited Partners
represented distributions of earnings on investments, in accordance with the
Partnership Agreement, as well as a return of capital for an unconsummated
investment.

Allocations of Proceeds

Pursuant to the terms of the Partnership Agreement, investment proceeds (as
defined in the Partnership Agreement) as to each investment are allocated
proportionately among the partners participating in such investment. Such
proceeds are further allocated between each limited partner and the General
Partner as follows:

       a.  The amount necessary to return the limited partner's required
           contribution in such investment and to return any realized or
           unrealized losses that partner has incurred on other investments will
           be allocated to the limited partner.

       b.  Any investment proceeds in excess of the amount in a. above will be
           allocated to the limited partner to provide a preferred return at the
           rate of 9% per annum on net cash investment made in such investment
           or any unpaid preferred return on other investments.

       c.  Any remaining investment proceeds will be allocated to the General
           Partner until the General Partner receives 25% of the amount
           allocated in b.

       d.  Any remaining investment proceeds will be allocated 80% to the
           limited partner and 20% to the General Partner.

The Partnership Agreement provides for a final allocation at the termination of
the Fund related to all investments of each limited partner. To the extent that
the final allocation to any limited partner exceeds the amounts previously
allocated, the General Partner shall, subject to certain limitations, refund
such amount to the Fund for distribution to the limited partner.

Profits and losses shall be allocated so that the capital account of each
partner is as equal as possible to the distribution that would be made if the
Fund were dissolved immediately after making such allocation.

Withdrawal and Admission of Partners

A limited partner shall not have the right to withdraw any of his capital from
the Fund except with the prior written consent of the General Partner. The
General Partner may, at its sole and absolute discretion, admit new limited
partners to the Fund before October 31, 1996. If admitted to the Fund prior to
October 31, 1996, a new limited partner shall remit to the Fund its initial
capital contribution, together with an additional amount (the "Subsequent
Admission Payment") computed from the date the Fund received each contribution,
until the date such payment is remitted to the Fund at an annual rate of 10%.
Any new limited partner admitted to the Fund after October 31, 1996 may only
participate and invest in investments made prior to admission with the approval
of the investment committee.


<PAGE>   11
                                      -4-


In October 1996, a new limited partner was admitted to the Fund under the
circumstances of the Partnership Agreement described above, participating and
investing in investments made since inception. The new limited partner paid
approximately $3,600,000 to the Fund, representing approximately $3,400,000 of
capital contributions (inclusive of incremental organizational costs and
management fees in accordance with the Partnership Agreement totaling $250,000)
and a Subsequent Admission Payment of approximately $200,000. The payment made
to the Fund by the new limited partner as well as the payments made by the Fund
pursuant to the Partnership Agreement to the initial limited partners are
included in contributions and distributions, respectively, in the statements of
changes in partners' capital.

4.  INVESTMENTS

The Fund is permitted to invest in privately placed securities. These securities
may be resold in transactions exempt, under certain conditions, from U.S. or
local security registration. However, prompt sale of such securities at an
acceptable price may be difficult. As of December 31, 1997 and 1996, 97% and 94%
of the Fund's net assets were invested in such securities, respectively.

Ontario-Quinta A.V.V.

The investment in Ontario-Quinta represents an equity interest in a holding
company which controls Luz del Sur, a Peruvian utility company that was
privatized in 1994 and went public in 1996, and TechnoSur, a services company
that was spun out of Luz del Sur and is publicly traded. The investment was
purchased on December 29, 1995. At December 31, 1996, the Fund valued the
investment based upon, among other factors, the prospects of the company, the
underlying market value of the shares of Luz del Sur and TechnoSur, comparable
utility companies and utility holding companies and the liquidity of the
investment. At December 31, 1997, the asset was valued at the underlying pro
rata market value of Luz del Sur and TechnoSur, and the sale of a portion of the
Ontario-Quinta investment subsequent to year-end.

Entre Rios S.A.

In May 1996, the Fund invested in Entre Rios, the private holding company of
Empresa Distribuidora de Entre Rios S.A. ("EDEER"). EDEER is a distributor and
transmitter of electric power in Argentina. At December 31, 1997 and 1996, the
investment was valued at cost based on, among other factors, the consideration
that the shares are not publicly traded, no further transactions have occurred
between the entities and other outside parties and no other matters have come to
the attention of management that would create a better estimate of current value
than the original cost.

Cataguazes-Leopoldina

On October 2, 1997, the Fund invested in Companhia Forca Luz,
Cataguazes-Leopoldina, a Brazilian Energy and Utility company. The Fund paid
$20,860,021 for the shares and capitalized $440,577 of costs involved in
researching and consummating the investment. Although the company is publicly
traded on Brazilian stock exchanges, it is not traded actively. As such, the
investment is currently considered nonmarketable by the Fund, and is carried at
cost at December 31, 1997.

5.  RELATED-PARTY TRANSACTIONS

Note Receivable

During 1995, the Fund received a note from the Fund Manager for $250,000. The
note is payable any time without penalty or upon termination of the management
agreement between the Fund and the Fund Manager. The note bears interest at the
rate of the three-month LIBOR. At December 31, 1997 and 1996, the balance
outstanding under this note was $246,716 and $250,000, respectively.

Management Fee

Effective October 31, 1995, the Fund Manager receives 1.25% of the Fund's
committed capital payable quarterly in advance as a basic management fee. For
the years ended December 31, 1997 and 1996, basic management fees of $741,856
and $774,621 respectively, have been recorded in the statements of operations.

Regional Advisor

In 1996, the Fund entered into an advisory agreement with FondElec America
Latina, Inc. (the "Regional Advisor"), an affiliate of the Fund Manager. The
advisory agreement provides that the Fund shall pay the Regional Advisor
$125,000 per annum plus reasonable out-of-pocket costs for a period of three
years. For the years ended December 31, 1997 and 1996, advisory fees of $125,000
have been paid to the Regional Advisor and are included in administrative
expenses in the statements of operations.

Financial Advisor

The Fund entered into a financial advisory agreement with an affiliate of a
limited partner pursuant to which the financial advisor shall advise the Fund of
financing options for each of the Fund's investments. The financial advisory
agreement provided that the Fund shall annually pay the financial advisor .25%
of the Fund's committed capital quarterly in advance. The Fund terminated the
financial advisor agreement at the end of the third quarter of 1997, and the
Fund Manager entered into a new agreement with the Financial Advisor on revised
terms. Such new agreement will not be paid for by the Partnership. For the years
ended December 31, 1997 and 1996, financial advisory fees of $113,068 and
$154,799, respectively, have been recorded in the statements of operations.

Technical Advisor

The Fund has entered into a technical advisory agreement with a limited partner
pursuant to which the technical advisor shall assist the Fund in evaluating
proposed investments. The technical advisory agreement provides that the Fund
shall annually pay the technical advisor reasonable employee overhead and
out-of-pocket expenses. There were no technical advisory fees incurred for the
years ended December 31, 1997 and 1996.

Due to Fund Manager

                  The financial information at December 31, 1996, has been
                  reclassified, for comparative purpose, in order to be

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)



                  d.       Receivables to be recovered from users

                           Such receivables arise from agreements entered into
                           with Provinces, Municipalities and other entities,
                           and are to be recovered from users currently
                           incorporated to the network and those to be
                           incorporated in the future to the networks installed
                           under the terms of those agreements, and are agreed
                           upon in cubic meters of gas. Said receivables have
                           been valued at the average tariff of the distributed
                           gas.

                  e.       Inventories

                           These have been valued at their replacement cost at
                           the end of the year; the values thereof do not exceed
                           their recoverable value.

                  f.       Fixed assets

                           The fixed assets transferred by Gas del Estado at the
                           beginning of operations of Camuzzi Gas del Sur S.A.
                           on December 28, 1992, have been valued in an overall
                           manner, according to the Contract for the Transfer of
                           the Company's shares of Gas del Estado. This value
                           has been restated in current Pesos at August 31,
                           1995.

                           The aforementioned value was recalculated for each
                           individual fixed asset, based on the inventory and
                           valuation carried out during the fiscal year ended
                           December 31, 1993 by independent consultants.

                           Additions carried out after such date and up to
                           August 31, 1995, were valued at their acquisition
                           cost, restated in current Pesos at such date. As from
                           September 1, 1995, additions have been valued at
                           their acquisition cost in current Pesos of the
                           corresponding period.

                           Up to September 30, 1995, additions of gas
                           distribution networks made free of charge were
                           recorded at their replacement cost at the time of the
                           transfer under the item "Other Income".

                           According to resolutions of the CNV adopted in the
                           meetings held on July 28 and August 16, 1995, the gas
                           distribution networks transferred after September 30,
                           1995, by users free of charge or partially funded by
                           third parties, shall be recorded at the lower of
                           their construction cost or the cost fixed for
                           transfer, or the cost of their value to the business.

                           In the case that the value of the asset added exceeds
                           the value of the consideration assumed by the
                           Licensee, or if such consideration does not exist
                           (free of charge), a cross-entry shall be recorded in
                           an adjustment account, which is shown deducted from
                           the Fixed Assets, whose depreciation criteria is
                           equivalent to that of the asset added.

                           The obligation to partially or totally compensate
                           third parties is recorded as a liability of the
                           Company.

                           The values thus determined are disclosed net of the
                           corresponding accumulated depreciation, calculated
                           using the straight-line method, based on the
                           estimated useful lives of the assets.

                           The value of the Fixed Assets, taken as a whole, does
                           not exceed their recoverable value.

                           out after September 1, 1995 are disclosed at their
                           acquisition cost in current Pesos of the
                           corresponding period, in both cases net of their
                           corresponding cumulative amortization, calculated
                           according to the straight-line method.

                  h.       Shareholders' equity

                           The Capital Stock has been stated at its nominal
                           value. The Capital Stock Adjustment represents the
                           difference between the nominal value of the capital
                           stock and its value adjusted, based on the
                           fluctuation in the general wholesale price index up
                           to August 31, 1995.

                           Changes in net worth prior to August 31, 1995 are
                           restated as of that date, while subsequent changes
                           are stated in the currency value of the corresponding
                           period.

NOTE 7:           ISSUANCE OF NOTES BY THE SUBSIDIARY

                  On December 11, 1996, together with Camuzzi Gas Pampeana S.A.,
                  Camuzzi Gas del Sur S.A. issued Notes not convertible into
                  shares under a Medium-Term-Note Program which was approved by
                  Certificate No. 136 of the CNV dated December 6, 1996.

                  Such issue was approved by the Board of Directors of the
                  Licensee on November 12, 1996; the main purpose of this issue
                  was to provide Camuzzi Gas del Sur S.A. with an important flow
                  of funds in order to (i) refinance Series B Notes for an
                  amount of U.S.$90,000,000 co-issued between Camuzzi Gas
                  Pampeana S.A. and Camuzzi Gas del Sur S.A. under a short- and
                  medium-term note program created by the shareholders at the
                  Shareholders' Meeting dated October 25, 1993; (ii) develop its
                  investment plans; (iii) pay up working capital and (iv)
                  refinance other liabilities.

                  The conditions for the issuance are as follows:

                  o Aggregate principal amount: U.S.$130,000,000
                  o Percentage corresponding to Camuzzi Gas del Sur S.A.: 38.89%
                  o Interest rate: 9 1/4%, payable semiannually in arrears.
                  o Price: 99.80%
                  o Maturity of principal: December 15, 2001.

                  The aforementioned program was created under a joint issuance
                  with Camuzzi Gas Pampeana S.A., and the two companies will be
                  jointly and severally liable for the payment of interest and
                  principal.

                  On May 9, 1997, the issued Notes were registered before the
                  United States Securities and Exchange Commission (SEC).

                           the existence of, any Lien upon its property, assets
                           or revenues, whether now owned or hereinafter
                           acquired, securing any indebtedness of any other
                           person, unless the Notes are equally and ratably
                           secured by such liens, except for:

                           (i)      Liens existing on the Issue Date of the

                                    the case may be, in conformity with
                                    Argentine professional accounting standards;

                                    preventing the forfeiture or sale of the
                                    property or assets subject to any such lien,

                           (vii)    Any liens imposed by operation of mandatory
                                    provisions of applicable law that do not
                                    materially affect the shareholders' equity
                                    Issuer's ability to perform its respective
                                    obligations under the Notes or Indenture;

                                    provided that (A) such extension, renewal or
                                    replacement does not extend to any property
                                    other than that originally subject to the
                                    liens being extended, renewed or replaced

                  Ratio: Neither of the Issuers shall permit the ratio of its
                  Net Worth to its Consolidated Indebtedness to be less than 1
                  to 1.

         (c)      Restrictions on Sale and Lease-Back Agreement: Neither of the
                  Issuers shall, nor shall either of the Issuers permit any
                  Subsidiary to, enter into any Sale and Lease-Back Agreement
                  with respect to any property unless (i) such agreement
                  involves a lease for a term of no more than three years by the
                  end of which it is intended that the use of such property by
                  the lessee shall be discontinued, (ii) such agreement is
                  between the Issuers, or between either or both of the Issuers
                  and a Subsidiary, or between Subsidiaries, (iii) the Issuers
                  or any Subsidiary would not be entitled to incur indebtedness
                  secured by a mortgage on the property involved in such
                  agreement at least equal in amount to the Attributable Debt
                  with respect to such Sale and Lease-Back Agreement, without
                  equally and ratably securing the Notes, (iv) the proceeds of
                  such agreement are at least equal to the fair market value
                  thereof (as determined in good faith by the Board of Directors
                  of each of the Issuers) and the Issuers apply an amount equal
                  to the greater of the net proceeds of such sale or the
                  Attributable Debt with respect to such Sale and Lease-Back
                  Agreement within 180 days of such sale to either (or a

                  or both of the Issuers or a Subsidiary (other than debt that
                  is subordinated to the Notes or debt to either or both of the
                  Issuers or a Subsidiary) that matures more than 12 months
                  after the creation of such debt or (B) the purchase,
                  construction or development of other comparable property, or
                  (v) such agreement is entered into within 120 days after the
                  initial acquisition by such Issuer or the Subsidiary, as the
                  case may be, of the property subject to such agreement.

         (d)      Merger, Consolidation or Sale of Assets: Neither of the

                  substantially all of its assets, whether by one transaction or
                  a series of transactions, to any person, (a) unless, in the
                  case of any such merger or consolidation, (i) such Issuer is
                  the successor person and (ii) any Noteholder who elects to be
                  guaranteed or repaid upon such merger or consolidation

                  of the Issuers, or (b) unless, in the case of any such other
                  transaction, (i) immediately after giving effect to such
                  transaction or series of transactions, no Event of Default or
                  event which, after the giving of notice or the lapse of time
                  or both, would constitute an Event of Default, will have
                  occurred and be continuing, (ii) the successor person is a
                  corporation that will expressly assume the obligations of such
                  Issuer under the Notes and the Indenture, and (iii) such
                  Issuer shall have delivered to the Trustee an officer's

                  conditions precedent therein relating to such transaction have

                  other conveyance or disposition of all or substantially all of
                  such Issuer's assets, the successor person will succeed to and
                  become substituted for the Issuer or both Issuers, as the case
                  may be, and may exercise every right and power of such Issuer
                  with the same effect as if it had been named in the Notes and
                  the Indenture and, thereafter, such Issuer will be released
                  from its liability as obligor on the Debt Securities and under
                  the Indenture.

NOTE 8:           RESTRICTIONS ON THE SUBSIDIARY'S ASSETS

                  Pursuant to the provisions of the terms and conditions for the
                  privatization of the natural gas distribution service, Camuzzi
                  Gas del Sur S.A. must obtain ENARGAS' prior consent, without
                  which the License may be revoked, to sell, assign, encumber or
                  dispose of assets essential for the service.

NOTE 9:           RECORDABLE ASSETS

                  As regards the real estate transferred under the Transfer
                  Contract, the Subsidiary Company has effected the
                  corresponding deeds with the Argentine General Notary Public,
                  and only isolated and irrelevant cases are pending.

                  Additionally, the Subsidiary completed the transfer of all the
                  vehicles.

NOTE 10:TAXES PAYABLE BY THE SUBSIDIARY

                  During the fiscal year ended December 31, 1995, the Licensee
                  availed itself of the installment payment plan established by
                  Decrees 314/95 and 316/95. The total amount refinanced is
                  Pesos 797,773, payable in equal monthly installments, the last
                  one falling due on May 16, 1999.

                  On January 30, 1998 the Subsidiary Company amended the Income
                  Tax Returns for the years 1993, 1994, 1995 and 1996 for a
                  total amount of Pesos 975,228. These amended tax returns are
                  attributable to the new tax determination related to the
                  amounts of the networks added by Camuzzi Gas del Sur S.A. up
                  to June 1995, by application of ENARGAS's Resolutions No. 269
                  and 389 dated February 8 and October 23, 1996.

NOTE 11:          GROSS SALES TAX OF THE SUBSIDIARY COMPANY

                  The Subsidiary Company received several tax assessments issued
                  by the provincial tax authorities, which are as follows:

                  PROVINCE OF BUENOS AIRES: The Province of Buenos Aires Revenue
                  Board (DPRPBA) made assessments questioning the Subsidiary
                  Company's Gross Sales Tax returns, and claiming Pesos 27,027
                  and Pesos 16,003 for the periods from December 1992 through
                  February 1995, and from March 1995 to June 1996, respectively,
                  not including fines and accessory charges. This difference
                  arises mainly from the fact that the Tax Authority claims that
                  the tax base on which the tax rate should be applied for
                  computing gross sales taxes on gas sales should include all
                  revenue obtained, as gas prices are no longer regulated by the
                  State after the privatization; therefore, the tax base is no
                  longer regulated by the provisions of Section 141, Subsection
                  (a) of the Tax Code.

                  The Subsidiary Company's position since the beginning of
                  operations is that the tax basis is the difference between the
                  selling and the purchasing price, based on the following:

                  (i)      The criterion used by the Subsidiary Company is based
                           on the fact that it has acted in compliance with the
                           provisions of Section 10, Subsection (a) of
                           decree-law 9006/78 compiled in 1985 restated text
                           -currently Section 141, Subsection (a) of the Fiscal
                           Code-, pursuant to the confirmation sent to Gas del
                           Estado S.E. by the Ministry of Economy and Public
                           Works and Services of the Province of Buenos Aires
                           through a notice dated February 27, 1986; such
                           provisions are deemed applicable since Camuzzi Gas
                           del Sur S.A. has taken over the activities of the
                           state company.

                  (ii)     The auditors hired by the Privatization Committee
                           concluded in their report to the Ministry of Economy
                           and Public Works and Services of the Argentine
                           Republic, that this tax should be calculated
                           according to the difference between the selling and
                           purchasing prices of gas sales, in order to comply
                           with the provisions of Law 24,076, regulating the gas
                           industry and the Distribution License.

                  (iii)    The documentation mentioned in (i) and (ii) was made
                           available to investors by the Government at the time
                           of the privatization of Gas del Estado S.E., in order
                           to provide them with all the information that could
                           affect their business and, accordingly, their bidding
                           prices in any manner whatsoever.

                  On May 26, 1996, the Licensee filed a motion to reconsider the
                  resolution of the Revenue Board of the Province of Buenos
                  Aires since it believed that it had acted, as stated before,
                  in compliance with the provisions of tax regulations. The
                  Company has cited the enforceability of the above-mentioned
                  regulation as the basis for its appeal for reversal.

                   SODIGAS SUR S.A. AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  On November 25, 1996, the General Revenue Board issued a Final
                  Opinion stating that, in its opinion, the Company must pay
                  gross sales tax on its total sales and not on its distribution
                  margin. On December 13, 1996, the General Revenue Board
                  further explained some points of the opinion indicating that,
                  according to such body is in representation, the change on the
                  tax criterion had derived from the fact that as from the
                  takeover of the natural gas distribution service by the
                  Licensees, the regulations set forth under the Fiscal Code
                  (Section 136, Subsection (e) and Section 141, Subsection (a))
                  are not valid, since the Government, upon withdrawing from the
                  business, no longer regulates the official selling prices.

                  Even though the Subsidiary Company's legal counsel considered
                  that the Company's defense was based on solid grounds, the
                  Final Opinion issued by the General Revenue Board
                  significantly changed the situation in that it explicitly
                  clarifies the tax criterion approved by the Province of Buenos
                  Aires and the change on the tax burden of the Licensee.
                  Therefore, because the Company is not legally required to
                  participate in a long judicial proceeding, the results of
                  which cannot be assured in spite of its sound defense, on
                  December 19, 1996, the Company availed itself of the Debt
                  Consolidation System pursuant to the provisions of the
                  provincial law 11,808. (Official Gazette, July 10, 1996).

                  The said regulations allow for the payment of the existing
                  debts corresponding to the period from December 29, 1992 to
                  January 31, 1996 in up to 48 installments, with a 1% monthly
                  interest on balances due for the extension granted. In
                  addition, default interest was reduced to 0.5% per month and
                  the penalties and fines were fully waived. Such regulations
                  further provide for an installment payment system for the
                  period between February 1, 1996 and August 31, 1996, and
                  allows for the settlement of all payments for the period
                  between September 1, 1996 and October 31, 1996, by means of
                  amended tax returns. The total balance included within these
                  Debt Consolidation Regulations amounted to Pesos 65,751 and
                  was accounted for by Camuzzi Gas del Sur S.A. under the "Taxes
                  Payable" caption.

                  Thus, as is evident from the above-mentioned conditions, the
                  Opinion of the General Revenue Board has modified the tax
                  system through the implementation of a new criterion which has
                  altered the Licensees tax burden generating a cost fluctuation
                  due to a "tax change", which was considered as a non-recurring
                  tariff adjustment by point 9.6.2. of the Distribution License
                  and by law 24,076.

                  In order to pass through this higher cost, pursuant to the
                  lawful right to which the Company is entitled, on December 20,
                  1996, Camuzzi Gas del Sur S.A. initiated formal proceedings by
                  filing a claim with ENARGAS to obtain the application of the
                  corresponding tariff adjustment. The claim for passing the tax
                  through to the tariffs was also filed before the Ministry of
                  Economy and Public Works and Services. In addition, the
                  Company, if deemed necessary shall exercise its right to
                  appeal to the Argentine Supreme Court of Justice, on the
                  grounds of a federal question regarding the indemnity rights
                  to which the Licensee is duly entitled.

                  Additionally, ENARGAS requested the opinion of the Revenue
                  Board of the Province of Buenos Aires. This Board ratified the
                  opinions mentioned above and requested some written
                  clarifications from the Ministry of Economy and Public Works
                  and Services, which had expressed its opinion through the
                  General Legal Affairs Board's opinion dated March 6, 1997 and
                  clarifying decision dated May 8, 1997, which confirmed the
                  Licensee's criterion. The answer to the aforementioned written
                  clarification dated July 18, 1997 ratified the previous
                  opinions.

                  Therefore, and as mentioned before, because a "change in tax
                  rules" generates a right for the Licensee to pass this change
                  on to the tariffs as envisaged in paragraph 9.6.2. of the
                  Distribution License and in Law No. 24,076, Camuzzi Gas del
                  Sur S.A. accounted for the amounts recognized as tax payable,
                  together with the payments made for the taxable basis of all
                  income from gas sales, with a balancing entry in the form of a
                  receivable to be collected from the users in future billings.

                  Through Resolution No. 544 dated November 17, 1997 and
                  pursuant to the regulatory framework of the activity, the
                  ENARGAS has authorized the pass-through to the tariffs of the
                  effects caused by the legal changes in the payment of the tax
                  in accordance with the methodology defined by that Regulatory
                  Authority in its note No. 108 dated January 12, 1998; the
                  decision on the pass-through to the tariffs related to the
                  effect on the sales to subdistributors and GNC stations is
                  still pending.

                  At December 31, 1997, the receivable to be recovered amounts
                  to Pesos 114,043 and has been recorded under "Other Current
                  Receivables" for the amount of Pesos 4,140 and under "Other
                  Non-Current Receivables" for the amount of Pesos 109,903.

                  PROVINCE OF CHUBUT: The Subsidiary Company filed a motion with
                  the General Revenue Board of the Province of Chubut to review
                  the case, answering a notice which questioned the Gross Sales
                  Tax Returns for the years 1993, 1994, 1995 through March,
                  1996, claiming differences in favor of the State amounting to
                  Pesos 1,775,289, without including interest or penalties.

                  In addition, the Subsidiary Company requested the annulment of
                  the service of a claim, for differences in the determination
                  of the gross sales tax returns amounting to Pesos 28,892, for
                  the period January-March 1993. As of the date hereof, the
                  amount claimed was deposited with the Court.

                   SODIGAS SUR S.A. AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  PROVINCE OF TIERRA DEL FUEGO: The Subsidiary Company was
                  served a notice by the Provincial General Revenue Board
                  rejecting the remedy for reconsideration filed, and requesting
                  the payment of Pesos 962,748 in respect of principal, not
                  including interest and penalties for the difference in the
                  gross income tax corresponding to the period from 1993 to June
                  1996. In addition, the Ministry of Economy and Public Works
                  and Services has rejected the appeal against the Resolution by
                  the General Revenue Board, so the Subsidiary Company can file
                  a claim in this connection in the future. On December 5, 1997,
                  the Subsidiary Company filed a motion before the governor of
                  the Province of Tierra del Fuego.

                  During the fiscal year, Camuzzi Gas del Sur S.A. set up a
                  provision of Pesos 761,023 as principal and interest which is
                  included in the caption "Provisions".

                  PROVINCE OF RIO NEGRO: The Subsidiary Company filed an answer
                  to the notice for the beginning of Summary Proceedings made by
                  the General Revenue Board of the Province of Rio Negro,
                  questioning the Gross Sales Tax Returns for the years 1993,
                  1994, 1995 through February, 1996, and subsequent notices for
                  the period March-August 1996, claiming differences in favor of
                  the State amounting to Pesos 2,711,583, not including interest
                  or penalties.

                  As regards the amount due mentioned in the first paragraph, a
                  court action was filed against the Licensee Company compelling
                  it to pay Pesos 2,080,007 for the principal with respect to
                  the difference in the gross income tax but for the period 1993
                  up to February 1996. The Subsidiary Company contested the
                  proceeding.

                  The Municipality rejected the motions and upon a judgment
                  pronounced against the Company, the Company filed an appeal to
                  that judgment. The remedy was sustained and the Company
                  submitted the briefs of the case.

                  PROVINCE OF NEUQUEN: The General Revenue Board of the Province
                  of Neuquen filed a record to settle accounts claiming
                  differences in favor of the government for Pesos 1,078,484,
                  not including interest and penalties. The Subsidiary Company
                  has duly filed the applicable answer.

                  In the opinion of the Subsidiary Company and its legal
                  advisors, an adverse decision in relation to the claims of the
                  Provinces of Chubut, Rio Negro, and Neuquen, is considered not
                  probable.

NOTE 12:          STAMP TAX OF THE SUBSIDIARY

                  Regards stamp tax, the situation is as follows:

                  PROVINCE OF RIO NEGRO: Camuzzi Gas del Sur S.A. filed a
                  motion, within such jurisdiction, asking for a preliminary
                  injunction with the Federal Judge in response to the
                  assessment of stamp tax under a Decree of the Executive Power,
                  whose amount has yet to be determined.

                  PROVINCE OF TIERRA DEL FUEGO: The Subsidiary Company filed an
                  answer to the Previous Notice made by the Revenue Board of the
                  Province of Tierra del Fuego, the Antarctic and South Atlantic
                  Islands, claiming the assessment of the stamp tax under a
                  Decree of the Executive Power, amounting to Pesos 140,000, not
                  including interest or penalties.

                  PROVINCE OF NEUQUEN: The General Revenue Board of that
                  province submitted an account claiming a difference favorable
                  to the Provincial Government for Pesos 1,656,205, not
                  including interests and penalties. Notice and decision on the
                  matter are expected so as to file the applicable answer.

                  Additionally, the General Revenue Board has made assessments
                  for a total of Pesos 1,827,518 on account of stamp tax on the
                  transfer of assets affected to the service. This claim was
                  filed jointly by Gas del Estado and the Subsidiary Company.
                  The Company has filed the applicable answer.

                  In the opinion of the Subsidiary Company and its legal
                  advisors, an adverse decision in relation to the
                  aforementioned claims is considered not probable.

NOTE 13: MUNICIPAL TAXES ON USE OF EASEMENTS BY THE SUBSIDIARY

                  Municipalities usually include a tax on easements in their tax
                  rules. Such rules are in conflict with federal regulations.

                  The distribution license grants the right to easements free of
                  charge to the Licensee and establishes that, if the
                  Municipalities levy any tax which is later ratified by a
                  court, the Subsidiary is authorized to pass through such cost
                  increase to the consumers.

                  Point 6.1 of the Distribution License reads as follows: "while
                  the Licensee is in charge of the service, it shall have the
                  right to use free of charge any street, avenue, square,
                  bridge, road and any other public place, including the
                  subjacent and air spaces, necessary for the installation of
                  facilities for the licensed service, including communication
                  lines and interconnections with

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  third parties". "However, if any definitive sentence by a
                  court admits the validity of the provincial or municipal
                  rules, which levy a tax on such easement or use upon the
                  Licensee, the Licensee may pass through such additional cost
                  to the consumers residing within the jurisdiction in which
                  such tax is applicable, according to ENARGAS' procedures
                  provided for in point 9.6.2, without any right of claim
                  against the Licensee or Gas del Estado".

                  Furthermore, pursuant to National Budget Law No. 24,624/95
                  corresponding to the 1996 year, in order to enjoy the
                  subsidies described therein, municipal taxes on easements must
                  be repealed as from January 1, 1996.

                  Currently, the following are the most relevant disputes in
                  relation to taxes on rights to subjacent space (subsoil):

                  MUNICIPALITY OF VIEDMA, PROVINCE OF RIO NEGRO: This
                  municipality brought an action against the Licensee for the
                  payment of the tax on subsoil rights totalling Pesos 246,400,
                  not including penalties and other expenses. The decision of
                  the Court of Appeals confirmed the judgement of first instance
                  for which an appeal for nullification was filed; this remedy
                  was rejected by the Supreme Court of the Province of Rio
                  Negro. An extraordinary remedy was further filed and denied as
                  well; the Company finally filed an appeal before the Argentine
                  Supreme Court of Justice requesting that the appeal dismissed
                  by the trial court be sustained. The judicial deposits made
                  during the year 1996 for an aggregate amount of Pesos 263,352,
                  are maintained plus Pesos 62,720 in respect of interest and
                  legal costs. Camuzzi Gas del Sur S.A. has set up a provision
                  for the aggregate amount claimed.

                  In addition, the Municipality has brought an action against
                  the Subsidiary Company for Pesos 148,148 in respect of
                  principal corresponding to the payment of the tax on subsoil
                  rights due for the year 1995. Camuzzi Gas del Sur S.A. has
                  contested the proceeding. The Municipality has contested the
                  motions and the entering of a judgment is expected. Judgment
                  was pronounced against the Camuzzi Gas del Sur S.A., which has
                  therefore filed an appeal; the appeal was sustained and the
                  Subsidiary Company has submitted the briefs of the case.
                  Expecting the Municipality to comply with its procedural
                  duties, the Court of Appeals interrupted the period to enter
                  judgment. The Subsidiary Company has made a provision of Pesos
                  95,545, which is included under the item "Provisions".

                  MUNICIPALITY OF NEUQUEN, PROVINCE OF NEUQUEN: The amount
                  claimed totals Pesos 66,524, not including penalties and other
                  accessories. The Municipality appealed the decision of the
                  Court of Appeals, on the grounds of lack of jurisdiction of
                  the provincial court to hear the case. The decision of the
                  court of Appeals was declared valid and the Supreme Court
                  dismissed the Camuzzi Gas del Sur S.A.'s claim of lack of
                  jurisdiction and ordered that the case be sent to the Court of
                  Appeal for judgement on the substance of the case. The Court
                  of Appeals rejected the motion filed by the Company and a
                  motion for lack of jurisdiction was filed with the Supreme
                  Court of Justice of the Province, and was rejected.

                  The Subsidiary Company is analyzing the possibility of filing
                  an independent action requesting the unconstitutionality of
                  the rules under which the occupation of public spaces by gas
                  installations is taxed, and also an injunction until the
                  matter under consideration is settled.

                  In addition, the Municipality lodged a new claim for the
                  period April 1996 - May 1997 for an amount of Pesos 97,421,
                  without including interest and penalties.

                  The claim was contested by means of a certified letter whereby
                  the Subsidiary Company was required to abandon the claim for
                  payment under the warning of having the subsidies suspended.
                  The Subsidiary Company has set up a provision of Pesos 49,892,
                  which is included in the "Provisions" caption.

                  MUNICIPALITY OF COMODORO RIVADAVIA: The Municipality claimed
                  from Camuzzi Gas del Sur S.A. the payment of taxes on rights
                  to public space which amount to Pesos 56,032, corresponding to
                  the first half of 1996. The claim is currently pending with
                  the Administrative Court upon discharge filed by the
                  Subsidiary Company

                  MUNICIPALITY OF ZAPALA: the principal amount claimed totals
                  Pesos 816,073 corresponding to the 1993, 1994, 1995 periods,
                  and January to November 1996.

                  The Subsidiary Company has filed a motion for reconsidering
                  such claim.

                  MUNICIPALITY OF VILLA REGINA: the amount claimed totals Pesos
                  1,939,343, not including penalties and accessory charges; the
                  Subsidiary Company has filed the relevant administrative
                  answer.

                  MUNICIPALITY OF CUTRAL-CO: the Municipality filed a claim for
                  the payment of Pesos 133,992, in respect of taxes on rights to
                  public space as from January 1993 through October 1996, net of
                  interest and legal costs. The Subsidiary Company contested the
                  proceeding. The judgment entered by the first instance court
                  rejected the motions and the Subsidiary Company appealed such
                  judgment and submitted the briefs of the case. The Subsidiary
                  Company has set up a provision of Pesos 71,296, which is
                  included in the "Provisions" caption.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  In the opinion of the Subsidiary Company and based on
                  judgmental elements obtained during the fiscal year, except
                  for the lawsuits with the Municipalities of Viedma, Cutral Co
                  and Neuquen, for which provisions were set up, an adverse
                  decision in relation to the aforementioned claims is
                  considered not probable.

NOTE 14: CONSTRUCTION FUNDED BY THIRD PARTIES

                  Construction funded by third parties, incorporated into the
                  Subsidiary Company's network during the fiscal years ended
                  December 31, 1997 and 1996, was the following:

</TABLE>



                  On February 8, 1996, ENARGAS issued Resolution No. 269/96,
                  which sets forth that regarding constructions fully or
                  partially funded by third party users, such users should
                  receive a discount based on the difference between the value
                  of the construction and the amount actually discounted for, if
                  any.

                  By means of ENARGAS' Resolution No. 389, dated October 23,
                  1996, the Regulatory Authority established the amounts to be
                  recognized to the users mentioned above, according to the
                  business value determined by such entity.

                  In compliance with this resolution, during the 1996 fiscal
                  year, the Subsidiary Company recorded a liability in an amount
                  estimated as the payment price in cubic meters of gas valued
                  according to the effective tariff rate charged to users, which
                  was debited from a reserve set up in previous fiscal years for
                  this purpose. In the case of those projects in which the
                  payments made by the Licensee differed from those set forth by
                  the Regulatory Authority, the liability corresponding to such
                  difference was accounted for. Both liabilities were valued at
                  current tariffs.

                  Furthermore, on February 3, 1997, by means of Resolution 422
                  the Regulatory Authority set the charges that the Gas
                  Distribution Companies shall have to recognize to third party
                  users financing network extension works; such amount results
                  from the business value set forth by ENARGAS. This Resolution
                  was only applicable to the works transferred to the Licensee
                  Companies during the year 1996.

                  As regards works to be financed by future customers, which may
                  be commenced and transferred to the network of the licensees
                  during the 1997 fiscal year, the Regulatory Authority issued
                  Rule No. 1877, dated May 23, 1997, whereby it established
                  provisionally a minimum bonus equivalent to 80% of the value
                  set forth in Exhibit I of ENARGAS' Resolution No. 422, in
                  accordance with the methodological guidelines included therein
                  and notwithstanding the further analysis to be made by the
                  Regulatory Authority, because it is the competent authority
                  regarding these matters.

                  As of the date hereof, the Subsidiary Company is taking the
                  necessary steps to implement the reimbursement of the cubic
                  meters duly suggested by the ENARGAS.

                  Subsequently, the ENARGAS, through Order No. 4,688 dated
                  December 30, 1997, modified the criterion previously
                  established by its Resolutions No. 389/96 and 422/96 and Order
                  No. 1877/96, in connection with the obligation of the
                  Distribution Service Licensees to grant provisions to third
                  party users who totally or partially paid undertakings related
                  to new networks or extensions thereof.

                  This amendment consists, basically, in the replacement of the
                  obligation of such users to file the documentation evidencing
                  their contribution, as called for by the above-mentioned
                  resolutions, by the execution of an affidavit in relation
                  thereof.

                  The above-mentioned order of ENARGAS has been challenged by
                  the Subsidiary Company on the grounds that it affects its
                  legitimate rights.

NOTE 15: FIVE-YEAR TARIFF REVIEW

                  On June 30, 1997, the Ente Nacional Regulador del Gas issued
                  Resolution No. 468 whereby it approved the five-year tariff
                  review and established new values for the K and X factors
                  corresponding to each tariff subsector; such values will be
                  applicable during the 1998-2002 five-year period.

                   SODIGAS SUR S.A. AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  Within the existing tariff scheme, the incorporation of these
                  two factors (Factor K of Investment and X of Efficiency) has
                  been contemplated; such factors will be added and subtracted
                  respectively from the distribution margin and, therefore, will
                  affect the final tariff for the next five-year period.

                  During the year, Camuzzi Gas del Sur S.A. submitted investment
                  projects for the determination of the K factor, which, once
                  reviewed by the ENARGAS, were approved at the end of October
                  for the Buenos Aires Sur, Tierra del Fuego, and Santa Cruz
                  subareas. Likewise, and due to the particularities of the
                  area, it has been decided the creation of the Cordillerana
                  subarea with a K factor related to support works in the
                  respective pipeline.

                  Simultaneously, the ENARGAS defined an efficiency factor (X)
                  of 4.6 % for Camuzzi Gas del Sur S.A. as from January 1, 1998,
                  which considers the improvements to be achieved in that
                  respect in the next five-year period, thus maintaining the
                  fair and reasonable profitability set forth by the Gas Law.

NOTE 16: EXTRAORDINARY LOSS

                  This item reflects the cost of the gas lost in the old network
                  of the General Mosconi neighborhood, in the city of Comodoro
                  Rivadavia, as of December 31, 1996.

                  This network was built by a local company with low quality
                  materials and without complying with the construction
                  standards in force for the construction of gas distribution
                  networks, resulting in several accidents. As a consequence of
                  this, a contract was entered into between the Municipality of
                  Comodoro Rivadavia, the above-mentioned company, and Camuzzi
                  Gas del Sur S.A., to renew the deteriorated network. As part
                  of this agreement, the customers would connect their inner
                  piping system to the new network.

                  Once the new network was built, the customers delayed their
                  connection citing economic difficulties. This situation led to
                  new negotiations with the Municipality, ENARGAS, the
                  construction company, and the customers who caused delays in
                  the discontinuance of the old network.

                  During the 1996 fiscal year, the operation of the damaged
                  network was discontinued, and gas is being supplied by the new
                  network for the benefit and safety of customers of the
                  above-mentioned neighborhood.

                  Furthermore, on December 31, 1996 the remainder balance
                  corresponding to claims arising from the collections of bills
                  due rendered by Camuzzi Gas del Sur S.A. as required by Gas
                  del Estado S.E. has been accounted for, pursuant to the
                  Transfer Contract Schedule XXI, net of the effect of such
                  items on the income tax.

                SODIGAS PAMPEANA S.A. AND ITS SUBSIDIARY COMPANY
                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
              For the fiscal years ended December 31, 1997 and 1996


NOTE 1:           FINANCIAL STATEMENT PRESENTATION

                  As required by General Resolution No. 290/97 of the Comision
                  Nacional de Valores (the "CNV"), which establishes that
                  consolidated financial statements must be submitted following
                  the procedure outlined in Technical Resolution No. 4 of the
                  Argentine Federation of Professional Councils of Economic
                  Sciences, the Balance Sheets of the Company at December 31,
                  1997 and 1996, and the Statements of Income and Cash Flows for
                  the fiscal years then ended have been consolidated on a
                  line-by-line basis with the financial statements of the
                  subsidiary.

                  Non-monetary items included in the Financial Statements at
                  December 31, 1997 and 1996, have been restated in current
                  Pesos up to August 31, 1995. No adjustments have been applied
                  since such date.

                  The information at December 31, 1996, has been reclassified,
                  for comparative purposes, to be consistent with that of the
                  current fiscal year.

                  The December 31, 1997 financial statements of the Subsidiary,
                  Camuzzi Gas Pampeana S.A., which cover the same fiscal year as
                  that of its Controlling Company, Sodigas Pampeana S.A., have
                  been used in order to determine the equity value and carry out
                  the consolidation.

NOTE 2:           VALUATION CRITERIA

                  The financial statements of the subsidiary have been prepared
                  based on criteria consistent with those applied for preparing
                  the financial statements of Sodigas Pampeana S.A.

                  In addition, the principal valuation and disclosure criteria
                  used for the preparation of the consolidated financial
                  statements at December 31, 1997 and 1996, are as follows:

                           The local currency assets and liabilities have been

                           including accrued interest.

                           The implicit cost of financing contained in the
                           monetary assets and liabilities has not been
                           segregated as it is not deemed significant.

                  b.       Foreign currency assets and liabilities

                           Foreign currency assets and liabilities were
                           translated at the exchange rate prevailing on the
                           balance sheet date, including accrued interest.

                           of the fiscal year.

                  d.       Other assets to be recovered from customers

                           These assets stem from agreements signed by Camuzzi
                           Gas Pampeana S.A. with provinces, municipalities and
                           other entities, to be recovered from customers who
                           are currently connected, or will be connected in the
                           future, to the network pursuant to the agreements.
                           These were agreed upon in cubic meters of gas and
                           have been valued at the average tariff for gas
                           distributed.

                  e.       Inventories

                           These have been valued at their replacement cost at
                           the end of the fiscal year; the value thereof does
                           not exceed their recoverable value.

                  f.       Fixed assets

                           The fixed assets transferred by Gas del Estado at the
                           beginning of the operations of Camuzzi Gas Pampeana
                           S.A. have been valued in an overall manner, according
                           to the contract for the transfer of the Company's
                           shares by Gas del Estado. This value has been
                           restated in current Pesos as at August 31, 1995.

                           The aforementioned value was recalculated for each
                           individual fixed asset, based on the stocktaking and
                           valuation carried out during the fiscal year ended
                           December 31, 1993 by independent consultants.

                           Additions carried out after such date and up to
                           August 31, 1995, were valued at their acquisition
                           cost, restated in current Pesos at such date. As from
                           September 1, 1995, additions have been valued at
                           their acquisition cost in current Pesos of the
                           corresponding period.

                           Up to September 30, 1995, additions of gas
                           distribution networks in favor of the Licensee
                           Company made free of charge, were recorded at their
                           replacement cost at the time of the transfer under
                           the item "Other Income".

                           According to resolutions of the CNV adopted in the
                           meetings held on July 28 and August 16, 1995, the gas
                           distribution networks transferred free of charge or
                           partially funded by third parties after September 30,
                           1995, shall be recorded at the lower of their
                           construction cost or the cost set for the transfer
                           and their value to the business.

                           In the case that the value of the asset added exceeds
                           the value of the consideration assumed by the
                           Licensee, or if such consideration does not exist
                           (free of charge), a cross-entry shall be recorded in
                           an adjustment account, which is shown deducted from
                           the Fixed Assets, whose depreciation criteria is
                           equivalent to that of the asset added.

                           The obligation to partially or totally compensate
                           third parties is recorded as a liability of the
                           Company.

                           The values thus determined are disclosed net of the
                           corresponding accumulated depreciation, calculated
                           using the straight-line method, based on the
                           estimated useful lives of the assets.

                           The value of the Fixed Assets, taken as a whole, does
                           not exceed their recoverable value.

                  g.       Intangible assets

                           This caption includes the purchase of computer
                           software and expenses in relation to the programs for

                           and its subsidiary, to be amortized over a five-year
                           period.

                           Additions of Intangible Assets made up to August 31,
                           1995 are recorded at their acquisition cost restated
                           in current Pesos at such date, while additions
                           carried out after September 1, 1995 are disclosed at
                           their acquisition cost in current Pesos of the
                           corresponding period, in both cases net of their
                           corresponding cumulative amortization, calculated
                           according to the straight-line method.

                  The Licensee has fulfilled in due time and manner the
                  mandatory investments for 1993, 1994, and 1996, and was
                  notified of such fulfillment by ENARGAS following an operating
                  audit of such investments. As a consequence of the differences
                  in criteria regarding the investments corresponding to the
                  year 1995, the Regulatory Authority has determined the
                  creation of a guarantee deposit by Camuzzi Pampeana S.A. for
                  an amount of U.S.$216,400 until the situation is settled.
                  Mandatory investments for the year 1997 are under examination
                  by the Regulatory Authority.

NOTE 7:           ISSUANCE OF NOTES BY THE SUBSIDIARY

                  On December 11, 1996, together with Camuzzi Gas del Sur S.A.,
                  Camuzzi Gas Pampeana S.A. issued jointly and severally Notes
                  not convertible into shares under a Medium-Term-Note Program
                  which was approved by Resolution No. 136 of the CNV dated
                  December 6, 1996.

                  Such issue was approved by the Board of Directors of the
                  Licensee on November 12, 1996; the main purpose of this issue
                  was to provide Camuzzi Gas Pampeana S.A. with an important
                  availability of funds in order to (i) refinance Series B of
                  the Notes in an aggregate principal amount of U.S.$90,000,000
                  issued jointly and severally with Camuzzi Gas del Sur S.A.
                  under the Notes Program approved by the Company's
                  Shareholders' Meeting dated October 25, 1993; (ii) develop its
                  investment plans; (iii) pay up working capital and (iv)
                  refinance other liabilities.

                  The conditions for the issuance are as follows:

                  . Aggregate principal amount: U.S.$130,000,000
                  . Percentage corresponding to Camuzzi Gas Pampeana S.A.:
                    61.11%

                  . Price: 99.80 %.
                  . Maturity of principal: December 15, 2001.

                  The aforementioned program was created under a joint issuance
                  with Camuzzi Gas del Sur S.A., and the two companies will be
                  jointly and severally liable for the payment of interest and
                  principal.

                  On May 9, 1997, the issued Notes were registered before the
                  United States Securities and Exchange Commission (SEC).

                  The main restrictions under the offering circular for the
                  issuance of Notes are the following:

                  (a)      Limitations on Liens: neither of the Issuers shall,
                           nor shall either of the Issuers permit any of their

                           or revenues, whether now owned or hereafter acquired,
                           securing any indebtedness of any person, unless the
                           Notes are equally and ratably secured by such Liens,
                           except for:

                           (i)      Liens existing on the Issue Date of the
                                    Notes:

                                    charges not yet due or which are being

                                    proceedings; provided that adequate reserves
                                    with respect thereto are maintained on the
                                    books of such Issuer or such Subsidiary, as
                                    the case may be, in conformity with
                                    Argentine professional accounting standards;

                  with respect to any property unless (i) such agreement
                  involves a lease for a term of no more than three years by the
                  end of which it is intended that the use of such property by
                  the lessee shall be discontinued, (ii) such agreement is
                  between the Issuers, or between either or both of the Issuers
                  and a Subsidiary, or between Subsidiaries, (iii) the Issuers
                  or any Subsidiary would not be entitled to incur indebtedness
                  secured by a mortgage on the property involved in such
                  agreement at least equal in amount to the Attributable Debt
                  with respect to such Sale and Lease-Back Agreement, without
                  equally and ratably securing the Notes, (iv) the proceeds of
                  such agreement are at least equal to the fair market value
                  thereof (as determined in good faith by the Board of Directors
                  of each of the Issuers) and the Issuers apply an amount equal
                  to the greater of the net proceeds of such sale or the
                  Attributable Debt with respect to such Sale and Lease-Back
                  Agreement within 180 days of such sale to either (or a
                  combination of) (A) the amortization (other than any mandatory
                  amortization, mandatory prepayment or sinking fund payment or
                  by payment at maturity) of debt for borrowed money of either
                  or both of the Issuers or a Subsidiary (other than debt that
                  is subordinated to the Notes or debt to either or both of the
                  Issuers or a Subsidiary) that matures more than 12 months
                  after the creation of such debt or (B) the purchase,
                  construction or development of other comparable property, or
                  (v) such agreement is entered into within 120 days after the
                  initial acquisition by such Issuer or the Subsidiary, as the
                  case may be, of the property subject to such agreement.

         (d)      Merger, Consolidation or Sale of Assets: Neither of the
                  Issuers will merge into or consolidate with any person or
                  sell, lease, transfer or otherwise convey or dispose of all or
                  substantially all of its assets, whether by one transaction or
                  a series of transactions, to any person, (a) unless, in the
                  case of any such merger or consolidation, (i) such Issuer is
                  the successor person and (ii) any Noteholder who elects to be
                  guaranteed or repaid upon such merger or consolidation
                  pursuant to Argentine law is so guaranteed or repaid by either
                  of the Issuers, or (b) unless, in the case of any such other
                  transaction, (i) immediately after giving effect to such
                  transaction or series of transactions, no Event of Default or
                  event which, after the giving of notice or the lapse of time
                  or both, would constitute an Event of Default, will have
                  occurred and be continuing, (ii) the successor person is a
                  company that will expressly assume the obligations of such
                  Issuer under the Notes and the Indenture, and (iii) such
                  Issuer shall have delivered to the Trustee an officer's
                  certificate and an opinion of counsel stating that such
                  merger, consolidation, sale, lease, transfer or other
                  conveyance or disposition complies with the Notes and that all
                  conditions precedent therein relating to such transaction have
                  been met. Upon the occurrence of any such merger,
                  consolidation, sale, lease, transfer or other conveyance or
                  disposition of all or substantially all of such Issuer's
                  assets, the successor person will succeed to and become
                  substituted for the Issuer or both Issuers, as the case may
                  be, and may exercise every right and power of such Issuer

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  with the same effect as if it had been named in the Notes and
                  the Indenture and, thereafter, such Issuer will be released
                  from its liability as obligor on the Debt Securities and under
                  the Indenture.

NOTE 8:           RESTRICTIONS ON THE SUBSIDIARY'S ASSETS

                  (a) Assets essential for the service

                  Pursuant to the provisions of the terms and conditions for the
                  privatization of the natural gas distribution service, the
                  Subsidiary Company must obtain ENARGAS' prior consent, without
                  which the License may be revoked, to sell, assign, encumber or
                  dispose of assets essential for the service.

                  (b) Restriction on funds

                  The Central Bank of the Argentine Republic (the "Central
                  Bank"), through Resolution No. 365 dated August 20, 1997,
                  resolved the full suspension of the transactions of Banco
                  Credito Provincial S.A., except for those transactions related
                  to the Central Bank derived from monetary and/or exchange
                  regulation transactions; transactions related to purchase and
                  credit cards existing as at such date; credit collection
                  transactions, mere custody administrative transactions or
                  those related to the compliance with labor, social security or
                  fiscal obligations; and the payment of pensions with funds
                  provided for by the National Administration of Social
                  Security.

                  In addition, on December 18, 1997, the Central Bank through
                  Resolution No. 741 authorized the group of major depositors of
                  Banco Credito Provincial S.A. to create a retail commercial
                  bank called Mercobank S.A., pursuant to the provisions of
                  section 7 of the Argentine Financial Institutions Law.

                  As of December 31, 1997, the funds deposited by the Subsidiary
                  Company in that institution amounted to Pesos 2,149,768. Such
                  funds are composed of Pesos 1,380,551 for retained collections
                  and Pesos 769,217 for fixed-term deposits, and have been
                  accounted for under "Other Receivables" classified as Current
                  and Non-Current, in accordance with the time when that the
                  Company considers it will collect such amount. The Company
                  expects to collect approximately 30% in cash, 40% in shares of
                  the new bank, and the remainder in Class C Bonds representing
                  the credit portfolio of Banco de Credito Provincial S.A.

                  The Company has decided to set up an allowance for Pesos
                  480,000 to be cross-entered under Extraordinary Loss. This
                  allowance represents the portion of uncertain recovery of the
                  value of the Class C Bonds, that the Company expects to
                  receive in the future.

NOTE 9:           RECORDABLE ASSETS

                  As regards the recordable real estate transferred under the
                  Transfer Contract, the Subsidiary Company has effected the
                  corresponding deeds with the Argentine General Notary Public,
                  and only isolated and irrelevant cases are pending.

                  Additionally, the Subsidiary completed the transfer of all the
                  vehicles.

NOTE 10: GROSS SALES TAX - PROVINCE OF BUENOS AIRES

                  The Province of Buenos Aires Revenue Board (DPRPBA) made
                  assessments questioning the Subsidiary Company's Gross Sales
                  Tax returns, and claiming Pesos 8,852,795 and Pesos 7,386,016
                  for the periods from December 1992 through February 1995, and
                  from March 1995 to June 1996, respectively, not including
                  fines and accessory charges. This difference arises mainly
                  from the fact that the Tax Authority claims that the tax base
                  on which the tax rate should be applied for computing gross
                  sales taxes on gas sales should include all revenue obtained,
                  as gas prices are no longer regulated by the State after the
                  privatization; therefore, the tax base is no longer regulated
                  by the provisions of Section 141, Subsection (a) of the Tax
                  Code.

                SODIGAS PAMPEANA S.A. AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  The Company's position since the beginning of operations is
                  that the tax basis is the difference between the selling and
                  the purchasing price, based on the following:

                  (i)      The criterion used by the Subsidiary Company is based
                           on the fact that it has acted in compliance with the
                           provisions of Section 10, Subsection (a) of
                           decree-law 9006/78 compiled in 1985 -currently
                           Section 141, Subsection (a) of the Fiscal Code-,
                           pursuant to the confirmation sent to Gas del Estado
                           S.E. by the Ministry of Economy and Public Works and
                           Services of the Province of Buenos Aires through a
                           note dated February 27, 1986, whose provisions are
                           deemed applicable since Camuzzi Gas Pampeana has
                           taken over the activities of such state company.

                  (ii)     The auditors hired by the Privatization Committee
                           concluded in their report to the Ministry of Economy
                           and Public Works and Services of the Argentine
                           Republic, that this tax should be calculated on the
                           difference between the selling and purchasing prices
                           of gas sales, in order to comply with the provisions
                           of Law 24,076, regulating the gas industry and the
                           Distribution License.

                  (iii)    The documentation mentioned in (i) and (ii) was made
                           available to investors by the Government upon the
                           privatization of Gas del Estado S.E., in order to
                           provide them with all the information that could
                           affect their business and, accordingly, their bidding
                           prices in any manner whatsoever.

                  (iv)     In addition, aiming at making a fairer business
                           management by the Subsidiary Company, it informed the
                           DPRPBA at the time it took over the business, through
                           a notice received by such body on January 15, 1993,
                           that it would continue to pay such tax following Gas
                           del Estado's practice, because it is the latter's
                           surviving company.

                  On May 26, 1996, the Licensee filed a motion to reconsider
                  DPRPBA's resolution since it believed that it had acted, as
                  stated before, in compliance with the provisions of tax
                  regulations. The Company has cited the enforceability of the
                  above-referenced regulation as the basis for its motion to
                  reconsider.

                  On November 25, 1996, the General Revenue Board issued a final
                  Opinion stating that, in its opinion, Camuzzi Gas Pampeana
                  S.A. must pay gross sales tax on its total sales and not on
                  the margin of distribution. On December 13, 1996, the General
                  Revenue Board further explained some points of the opinion
                  indicating that, according to such body, the change of
                  criterion had derived from the fact that as from the takeover
                  of the natural gas distribution service by the Licensees, the
                  regulations set forth under the Fiscal Code (Section 136,
                  Subsection (e) and Section 141, Subsection (a)) are not valid,
                  since the Government, upon withdrawing from the business, no
                  longer regulates the official selling prices.

                  Additionally, during the months of October and November 1996,
                  some properties belonging to the Licensee and located
                  throughout the Province of Buenos Aires were attached for the
                  amount of Pesos 30,000,000, which sum includes principal,
                  interest and fines. After several claims by the Company, the
                  attachment was discharged on the condition that the Company
                  availed itself of the Debt Consolidation Regulations ("Regimen
                  de Consolidacion de Deudas") under Law 11,808 and provided
                  that in the event that the Company fails to avail itself to
                  such Regulations, such attachments could be levied again over
                  such assets or bank accounts, thus having an adverse effect on
                  the subsidiary Company.

                  Even though the Subsidiary Company's legal counsel considered
                  that the Company's defense was based on solid grounds, the
                  Final Opinion issued by the General Revenue Board
                  significantly changed the situation in that it explicitly
                  clarifies the tax criterion approved by the Province of Buenos
                  Aires and the change in the tax burden of the Licensee.
                  Therefore, because the Company was not legally required to
                  participate in a long judicial proceeding, the results of
                  which could not be assured in spite of its sound defense, and
                  because its property would be subject to attachment during the
                  course of such proceeding, on December 19, 1996, the Company
                  availed to the Debt Consolidation Regulations pursuant to the
                  provisions of the provincial law 11,808. (Official Gazette,
                  July 10, 1996).

                  The said regulations allowed for the payment of the existing
                  debts corresponding to the period from December 29, 1992 to
                  January 31, 1996 in up to 48 installments, with a 1% monthly
                  interest on balances due for the extension granted. In
                  addition, default interest was reduced to 0.5% per month, and
                  the penalties and fines were fully waived. Such regulations
                  further provide for an installment payment system for the
                  period between February 1, 1996 and August 31, 1996, and
                  allows for the settlement of all payments for the period
                  between September 1, 1996 and October 31, 1996, by means of
                  amended tax returns. The total balance included within these
                  Debt Consolidation Regulations amounted to Pesos 23,164,958
                  and was accounted for by Camuzzi Gas Pampeana S.A. under the
                  caption "Tax Payable".

                  Thus, as is evident from the above-mentioned conditions, the
                  Opinion of the General Revenue Board modified the tax system
                  through the implementation of a new criterion which altered
                  the Licensee's tax burden, generating a cost fluctuation due
                  to a "tax change" which was considered as a non-recurring
                  tariff adjustment by point 9.6.2. of the Distribution License
                  and by law 24,076.

                  In order to pass through this higher cost, pursuant to the
                  lawful right to which the Company is entitled, on December 20,
                  1996, Camuzzi Gas Pampeana S.A. initiated formal proceedings
                  by filing a claim with ENARGAS to obtain the application of
                  the corresponding tariff adjustment. The claim for passing the
                  tax through to the tariffs was also filed before the Ministry

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  of Economy and Public Works and Services. In addition, the
                  Company shall exercise its right to appeal to the Argentine
                  Supreme Court of Justice, if necessary, on the grounds of a
                  federal question regarding the indemnity rights to which the
                  Licensee is duly entitled.

                  Additionally, ENARGAS requested the opinion of the Revenue
                  Board of the Province of Buenos Aires, which ratified the
                  opinions mentioned above and requested some written
                  clarifications from the Ministry of Economy and Public Works
                  and Services, which had expressed its opinion through the
                  General Legal Affairs Board's opinion dated March 6, 1997 and
                  clarifying decision dated May 8, 1997, which confirmed the
                  Company's criterion. The answer to the aforementioned written
                  clarification dated July 18, 1997 ratified the previous
                  opinions.

                  Therefore, and as mentioned before, because a "change of tax
                  rules" generates a right for the Company to pass this change
                  on to the tariffs as envisaged in paragraph 9.6.2. of the
                  Distribution License and in Law No. 24,076, Camuzzi Gas
                  Pampeana S.A. accounted for the amounts recognized as tax
                  payable, together with the payments made for the taxable basis
                  of all income from gas sales, with a balancing entry in the
                  form of a receivable to be collected from the users in future
                  billings.

                  Through Resolution No. 544 dated November 17, 1997 and
                  pursuant to the regulatory framework of the activity, the
                  ENARGAS has authorized the pass-through to the tariffs of the
                  effects caused by the legal changes in the payment of the tax
                  in accordance with the methodology defined by that Regulatory
                  Authority in its note No. 108 dated January 12, 1998; the
                  decision on the pass-through the tariffs related to the effect
                  on sales to subdistributors and GNC stations is still pending,
                  and the amount totals Pesos 202,845.

                  At December 31, 1997, the receivable to be recovered amounts
                  to Pesos 28,848,605 and has been recorded under the caption
                  "Other Current Receivables" for the amount of Pesos 2,568,842
                  and in "Other Non-Current Receivables" for the amount of Pesos
                  26,279,763.

NOTE 11: TAXES PAYABLE BY THE SUBSIDIARY COMPANY

                  During the fiscal year ended December 31, 1995, Camuzzi Gas
                  Pampeana S.A. availed itself of the installment payment plan
                  established by Decrees 314/95 and 316/95. The total amount
                  refinanced is Pesos 1,389,277, payable in equal monthly
                  installments, the last one falling due on May 16, 1999.

                  On January 30, 1998 the Subsidiary Company corrected the
                  Affidavits of Income Taxes for the years 1993, 1994, 1995 and
                  1996 for a total amount of Pesos 1,590,639. These corrections
                  are attributable to the new tax determination related to the
                  amounts of the networks incorporated by the Camuzzi Gas
                  Pampeana S.A. up to June 1995, by application of ENARGAS's
                  Resolutions No. 268 and 356 dated February 8 and August 22,
                  1996.

NOTE 12: CONSTRUCTION FUNDED BY THIRD PARTIES

                  Subsidiary Company's network during the fiscal years ended

</TABLE>



                  On February 8, 1996, ENARGAS issued Resolution No. 268/96,
                  which sets forth that regarding construction fully or
                  partially financed by third party users, such users should
                  receive a discount based on the difference between the value
                  of the construction and the amount actually discounted, if
                  any.

                  By means of ENARGAS' Resolution No. 356, dated August 22,
                  1996, the Regulatory Authority established the amounts to be
                  recognized to the users mentioned above according to the
                  business value determined by such entity.

                  In compliance with this resolution, regarding networks
                  transferred free of charge, during the fiscal year 1996, the
                  Subsidiary Company recorded a liability in an amount estimated
                  as the payment price in m3 of gas which was debited from a
                  reserve set up in previous years for this purpose. In those
                  projects in which the payments made by the Licensee differed
                  from those set forth by the Regulatory Authority, the
                  liability corresponding to such difference was accounted for.
                  Both liabilities were valued at current tariffs.

                SODIGAS PAMPEANA S.A. AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  Furthermore, on February 3, 1997, by means of Resolution 422
                  the Regulatory Authority set the charges that the Gas
                  Distribution Companies shall have to pay to third party users
                  financing network extension works; such amount results from
                  the business value set forth by ENARGAS. This Resolution was
                  only applicable to works transferred to the Licensee Companies
                  in 1996.

                  As regards works to be financed by future clients, commenced
                  and transferred to the net worth of the Licensees in 1997, the
                  Regulatory Authority issued Rule No. 1,877, dated May 23,
                  1997, whereby it established provisionally a minimum discount
                  equivalent to the 80% of the value set in Exhibit I of
                  ENARGAS' Resolution No. 422, in accordance with the
                  methodological guidelines included therein, and
                  notwithstanding the further analysis to be made by the
                  Regulatory Authority, because it is the competent authority
                  regarding these matters.

                  As of the date hereof the Subsidiary Company has taken the
                  necessary steps to implement the reimbursement of the cubic
                  meters duly suggested by the ENARGAS.

                  Subsequently, the ENARGAS, through Order No. 4,688 dated
                  December 30, 1997, modified the criteria previously
                  established by its Resolutions No. 356/96 and 422/96 and Order
                  No. 1877/96, in connection with the obligation of the
                  Distribution Service Licensees to grant provisions to third
                  party users who totally or partially paid undertakings related
                  to new networks or extensions thereof.

                  This amendment consists, basically, in the replacement of the
                  obligation of such users to file the documentation evidencing
                  their contribution, as called for by the above-mentioned
                  resolutions, by the execution of an affidavit in relation
                  thereof.

                  The above-mentioned order of ENARGAS has been challenged by
                  the Company on the grounds that it affects its legitimate
                  rights.

NOTE 13: MUNICIPAL TAXES ON USE OF EASEMENTS BY THE SUBSIDIARY

                  Municipalities usually include a tax on easements in their tax
                  rules. Such rules are in conflict with federal regulations.

                  The Distribution license grants the right to easements free of
                  charge to the Licensee and establishes that, if the
                  municipalities levy any tax which is later ratified by a
                  court, the Subsidiary is authorized to pass through such cost
                  increase to the consumers.

                  Point 6.1 of the Distribution License reads as follows: "while
                  the Licensee is in charge of the service, it shall have the
                  right to use free of charge any street, avenue, square,
                  bridge, road and any other public place, including the
                  subjacent and air spaces, necessary for the installation of
                  facilities for the licensed service, including communication
                  lines and interconnections with third parties".

                  However, if any definitive sentence by a court admits the
                  validity of the provincial or municipal rules, which levy a
                  tax on such easement or use upon the Licensee, the Licensee
                  may pass through such additional cost to the consumers
                  residing within the jurisdiction in which such tax is
                  applicable, and the Regulatory Entity shall act in accordance
                  with the procedures provided for in point 9.6.2, without any
                  right of claim against the Licensee or Gas del Estado.

                  Furthermore, pursuant to National Budget Law No. 24,624/95
                  corresponding to the 1996 year, in order to enjoy the
                  subsidies described therein, municipal taxes on easements must
                  be repealed as from January 1, 1996.

                  Currently, the following are the most relevant disputes in
                  relation to taxes on rights to subjacent space (subsoil):

                  MUNICIPALITY OF ENSENADA, PROVINCE OF BUENOS AIRES: This
                  Municipality brought an action for the payment of the tax on
                  subsoil rights for Pesos 6,265,513, in respect of principal,
                  and obtained a favorable judgment by the Lower Court. The
                  Licensee filed an appeal with the Court of Appeals of La
                  Plata, which revoked the Lower Court's decision, and
                  acknowledged the national exemption granted to the Subsidiary
                  for the use of public spaces. The Court of Appeals of La Plata
                  rejected the extraordinary remedy filed by the Municipality of
                  Ensenada and, as a result of which, the Municipality submitted
                  a claim for Reconsideration to the Supreme Court of the
                  Argentine Republic, which was rejected on October 3, 1997,
                  thus, ending the controversy brought forward by the
                  Municipality.

                  MUNICIPALITY OF LA PLATA, PROVINCE OF BUENOS AIRES: On October
                  19, 1995, the licensee company was served an official
                  assessment from the Municipality of La Plata for the payment
                  of Pesos 2,730,141 not including penalties and other expenses.
                  The Subsidiary Company contested the claim before the
                  administrative authorities within the terms authorized by such
                  Municipality.

                  MUNICIPALITY OF SANTA ROSA, PROVINCE OF LA PAMPA: The amount
                  claimed totals approximately Pesos 69,078, without interest
                  and penalties.

                SODIGAS PAMPEANA S.A. AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  The Lower Court sustained the claim and rejected the
                  objections filed by the Company. Camuzzi Gas Pampeana S.A.
                  appealed to the Court of Appeals which also sustained the
                  decision.

                  The Licensee filed an appeal against the judgment and obtained
                  a favorable resolution from the competent court. Thereafter,
                  the appeal was rejected based on a motion to reverse the
                  judgment filed by the Municipality. The Supreme Court of the
                  Province rejected our Provincial extraordinary motion. An
                  extraordinary motion was filed with the Federal courts against
                  such decision, which proceedings will be held before the
                  Supreme Court of the Argentine Republic. The Supreme Court of
                  the Argentine Republic has rejected the Extraordinary Remedy
                  filed by the Subsidiary Company and this Company has further
                  submitted a Claim for Reconsideration to the Supreme Court of
                  the Argentine Republic, which claim was rejected.

                  The amount claimed has been deposited with the court. As of
                  the date hereof, the Subsidiary Company has set up an
                  allowance for the total amount claimed.

                  MUNICIPALITY OF SALADILLO, PROVINCE OF BUENOS AIRES: The
                  principal amount claimed totals Pesos 55,542.

                  The claim was submitted and is pending consideration by the
                  administrative court with an answer filed by Camuzzi Gas
                  Pampeana S.A.

                  MUNICIPALITY OF REALICO, PROVINCE OF LA PAMPA: The principal
                  amount claimed totals Pesos 4,137. The Licensee has answered
                  the complaint contesting the action. Thereafter, a judgment
                  rejecting our objections was entered.

                  MUNICIPALITY OF CORONEL SUAREZ, PROVINCE OF BUENOS AIRES: The
                  principal amount claimed totals Pesos 6,300. The Subsidiary
                  Company has filed a remedy for reconsideration.

                  MUNICIPALITY OF LAS FLORES, PROVINCE OF BUENOS AIRES: The
                  principal amount claimed totals Pesos 9,736. The Subsidiary
                  Company has filed a remedy for reconsideration which was
                  rejected by the Municipality.

                  In the opinion of the Licensee and based on judgmental
                  elements obtained during the year, and except for the lawsuits
                  with the Municipality of Santa Rosa, for which provisions have
                  been set up, an adverse decision in relation to the
                  aforementioned claims is considered not probable.

NOTE 14: FIVE-YEAR TARIFF REVIEW

                  On June 30, 1997, the Ente Nacional Regulador del Gas issued
                  Resolution No. 468 whereby it approved the five-year tariff
                  review and established new values for the factors K and X per
                  tariff subzone for the 1998-2002 five-year period.

                  Within the tariff scheme set forth in the Resolution, the
                  incorporation of these two factors (Factor K of Investment and
                  X of Efficiency) has been contemplated; such factors will be
                  added and subtracted respectively from the margin of
                  distribution and, therefore, will affect the final tariff for
                  the next five-year period.

                  During the year, the Subsidiary Company submitted investment
                  projects for the determination of the K factor, which, once
                  reviewed by the ENARGAS, were approved at the end of October
                  for the La Pampa Norte subarea, and which will be in force as
                  from the second semester of 1998.

                  Simultaneously, the ENARGAS defined an efficiency factor (X)
                  of 4.5% for the Subsidiary Company as from January 1, 1998,
                  which considers the improvements to be achieved in that
                  respect in the next five-year period.

NOTE 15: EXTRAORDINARY INCOME/LOSS

                  At December 31, 1996 the remainder balance corresponding to
                  claims arising from the collection of bills due rendered by
                  the Camuzzi Gas Pampeana S.A. as required by Gas del Estado
                  S.E. has been accounted for pursuant to the Transfer Contract
                  Schedule XXI, net of the effect of such items on the income
                  tax.
