letters of credit during 1998 was $8,250,000 with $8,000,000 remaining
outstanding as of December 31, 1998.
 
CNG Retail has obtained a letter of credit in the amount of $250,000 in favor of
Columbia Gas of Pennsylvania to participate in that company's pilot program. The
letter of credit is in effect through September 1999.
 
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).

(3)  In January 1998, the Parent Company purchased 4,558,500 shares at a cost of
     $252,427,000, or $55.375 a share, in a private transaction to satisfy the

     subordinated debentures. Of these shares, 1,638,185 were issued on
     conversion. The remaining 2,920,315 shares were sold in two underwritten
     offerings in February and March, 1998. Also during 1998, the Parent Company

ITEM 9.  WHOLESALE GENERATORS AND FOREIGN UTILITY COMPANIES
 
Part I. Information concerning the interests held by system companies in exempt
        wholesale generators or foreign utility companies:
 
1. Information concerning the interests held by system companies in exempt
wholesale generators follows.
 
On November 20, 1998, CNG Power, a wholly owned subsidiary of the Company, sold
its 34% limited partnership interest in Lakewood Cogeneration, L.P. (Lakewood
Partnership) to Hydra-Co Enterprises, Inc. for $16.5 million. On the same date,
CNG Power Services, a wholly owned subsidiary of the Company, sold all of the
outstanding capital stock of CNG Lakewood to HCE Lakewood, Inc. for $.5 million.
CNG Lakewood, a former wholly owned subsidiary of CNG Power Services, owned a 1%
general partnership interest in the Lakewood Partnership. As of December 31,
1998, the Company had no investment remaining in the Lakewood Partnership nor
did the Company have any other investments in exempt wholesale generators.
 
2. Information concerning the interests held by system companies in a foreign
utility company (FUCO) follows.
 
(a) Latin America Fund
 
CNG International holds a 16.5% limited partnership interest in The Latin
America Energy and Electricity Fund I, L.P. (Latin America Fund), a Cayman
Islands exempted limited partnership, and an 8.29% general partnership interest
in FondElec General Partner, L.P. (FondElec). FondElec holds a 1% general
partnership interest in the Latin America Fund. CNG International obtains an
indirect ownership interest, equal to its percentage ownership interest in the
partnership, in each of the Latin America Fund's investments. Until Mid-1998,
the Latin America Fund's business was limited to investing in FUCOs in Latin
America. The Latin America Fund had investments in three FUCOs and a foreign
pipeline as of December 31, 1998.
 
The name and business address of the Latin America Fund are as follows:
 
        The Latin America Energy and Electricity Fund I, L.P.
        Stamford Harbor Park, 333 Ludlow Street, Stamford, CT 06902
 
(b) At December 31, 1998, CNG International's investment in the Latin America
Fund totaled $9,158,000. CNG International's total commitment for investment in
the Latin America Fund is $10,000,000. The balance will fund additional
investments and operating costs. There have been no transfers of assets from a
CNG affiliate to any FUCO in which the Latin America Fund has an interest.
 
(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 $2,847,538 for the year ended
December 31, 1998.
 
(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 other interests held by system companies in FUCOs
follows.
 
(a) Argentine FUCOs
 
In December 1997, CNG International acquired ownership interests in two gas
utility holding companies, Sodigas Pampeana S.A. and Sodigas Sur S.A., and in an
electric utility holding company, Buenos Aires Energy Company (BAECO), from CEI
Citicorp Holdings S.A. in Argentina. In March 1998, CNG International purchased
additional interests in Sodigas Pampeana, S.A., Sodigas Sur S.A. and BAECO
bringing the Company's ownership interests in these entities to 21.55%, 21.55%,
and 25%, respectively. 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.

ITEM 9.  WHOLESALE GENERATORS AND FOREIGN UTILITY COMPANIES (Concluded)
 
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 358,000 customers in Argentina to the south of Buenos Aires.
Camuzzi Pampeana and Camuzzi del Sur own, in the aggregate, approximately 5,400
miles of natural gas pipelines and 19,000 miles of natural gas distribution
mains and networks. Camuzzi Pampeana and Camuzzi del Sur together sell
approximately 235 Bcf of natural gas per year.
 
EDEA serves approximately 400,000 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.

ITEM 10.  (Continued)
 
                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders of
Consolidated Natural Gas Company
 
In our opinion, the consolidating financial statements of Consolidated Natural
Gas Company listed in the accompanying index on page 23 together with the Notes
thereto incorporated by reference to Exhibit 99 to the Company's Annual Report
on Form 10-K for the year ended December 31, 1998 present fairly, in all
material respects, the consolidated financial position of Consolidated Natural
Gas Company and its subsidiaries at December 31, 1998, 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 106 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 106 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.

* During April 1998, management approved a plan to discontinue the Company's
  wholesale trading and marketing of natural gas and electricity, including
  integrated energy management. The results of operations of these activities
  are classified as "Discontinued Operations" in the Consolidating Income
  Statement. Cash flows in connection with operating and investing activities
  for discontinued operations are reported separately in the Consolidating
  Statement of Cash Flows. On July 31, 1998, the Parent Company sold all of the
  common stock of CNG Energy Services. Prior to the sale, CNG Energy Services
  transferred all of the common stock of its subsidiaries to the Parent Company
  through a liquidating distribution. Subsequent to the distribution, each of
  the subsidiaries became a direct subsidiary of the Parent Company.

  Statement. The remaining net liabilities associated with discontinued
  operations at December 31, 1998 are classified on one line item, Other current
  liabilities, in the Consolidating Balance Sheet. Cash flows in connection with
  operating and investing activities for discontinued operations are reported
  separately in the Consolidating Statement of Cash Flows.

shall be limited to the purposes stated in the notice.

4.       QUORUM AND VOTING AT MEETINGS

         4.01 The holders of a majority of the stock issued and outstanding and
entitled to vote, present in person or represented by proxy, shall 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-laws. If, however,

the stockholders entitled to vote, present in person or represented by proxy,
shall have the power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall be present or
represented. At such adjourned meeting at which a quorum shall be present or
represented, any business may be transacted which might have been transacted at
the meeting as originally notified.

         4.02 When a quorum is present at any meeting, the vote of the holders
of a majority of the stock having voting power, present in person or represented
by proxy, shall decide any question brought before such meeting, unless the
question is one upon which a different vote is required by express provision of
a statute or the charter or these by-laws, in which case such express provision
shall control the decision of such question.

         4.03 At any meeting of stockholders, every stockholder having the right
to vote shall be entitled to vote in person or by proxy appointed by an
instrument in writing subscribed by such stockholder or authorized agent and
bearing a date not more than eleven months prior to said meeting, unless such

         4.04 In all elections of directors each stockholder may cast one vote
for each share of stock having voting power owned by such stockholder for as
many persons as there are directors to be elected, or such stockholder may
cumulate such votes and give one candidate as many votes as the number of
directors to be elected multiplied by the number of such shares of stock, or
such votes may be distributed on the same principle among as many candidates for
director as such stockholder may desire.

         4.05 The person presiding at any meeting of stockholders may appoint

specify the purpose thereof.

plan), where such service was specifically requested by the Corporation in

participation in outside positions (such service hereinafter being referred to

fines, and amounts paid in settlement ("Loss") actually and reasonably incurred

the Corporation to provide broader indemnification rights than said Law
permitted the Corporation to provide prior to such amendment). The Corporation
shall indemnify any person seeking indemnity in connection with any Proceeding
(or part thereof) initiated by such person only if such Proceeding (or part
thereof) initiated by such person was authorized by the Board of Directors of
the Corporation. With respect to any Loss arising from Outside Service, the
Corporation shall provide such indemnification only in and to the extent that
(a) such other company, partnership, joint venture, trust, association, or
enterprise is not legally permitted or financially able to provide such
indemnification, and (b) such Loss is not paid pursuant to any insurance policy
other than any insurance policy maintained by the Corporation.

         15.02 The right to be indemnified pursuant hereto shall include the
right to be paid by the Corporation for expenses, including attorney's fees,
incurred in defending any such Proceeding in advance of its final disposition;
provided, however, that the payment of such expenses in advance of the final
disposition of such Proceeding shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such director, officer,
fiduciary, or other representative, in which such director, officer, fiduciary,
or other representatives agrees to repay all amounts so advanced if it should be
determined ultimately that such director, officer, fiduciary, or other
representative is not entitled to be indemnified under applicable law.

         15.03 The right to be indemnified or to the reimbursement or
advancement of expenses pursuant hereto shall in no way be exclusive of any
other rights of indemnification or advancement to which any such director or
officer, fiduciary, or other representative 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, fiduciary, or other representative and shall inure to the
benefit of the heirs, executors, and administrators of such person.

         15.04 Any person who is serving or has served as a director, officer,
or fiduciary of (a) another corporation of which a majority of the shares
entitled to vote in the election of its directors is held by the Corporation at

have entered into an Agreement dated December 31, 1994 for the allocation of
current federal income taxes; and

         WHEREAS, Parent and its subsidiaries (hereinafter collectively referred
to as the "Companies") are desirous of amending the agreement for the purpose of
giving recognition to ownership changes of certain subsidiaries within the
consolidated group as a result of the partial liquidation and sale of the stock
of one of the subsidiaries and a change in the name of one of the subsidiaries.

         NOW, THEREFORE, the Companies, for the mutual benefit and valuable
considerations, do hereby covenant and agree with one another that, pursuant to
paragraph IV of the Agreement, it shall be amended as follows:

         First:   CNG Main Pass Gas Gathering Corporation and CNG Oil Gathering
                  Corporation, both incorporated in the State of Delaware on
                  July 21, 1995, CNG Products and Services, Inc., incorporated
                  in the state of Delaware on August 28, 1995, CNG Retail
                  Services Corporation, incorporated in the state of Delaware on
                  January 30, 1997, CNG Power Company, incorporated in the state
                  of Delaware on October 26, 1981, CNG Storage Services Company,
                  incorporated in the state of Delaware on July 19, 1977, all
                  wholly-owned subsidiaries of CNG Energy Services Corporation,
                  became wholly-owned subsidiaries of the Parent as a result of
                  a liquidation distribution made on July 30, 1998.

         Second:  CNG Storage Services Company was renamed as CNG Field Services
                  Company on September 28, 1998.

         Third:   The stock of CNG Energy Services Corporation, formerly a
                  wholly-owned subsidiary of the Parent, was sold to Sempra
                  Energy Trading Corporation, an outside party, effective July
                  1, 1998. As a result of this transaction, CNG Energy Services
                  Corporation is no longer a party to the Agreement, effective
                  as of that date.

Accountants


TO THE PARTNERS OF
IROQUOIS GAS TRANSMISSION SYSTEM, L.P.:

In our opinion, the accompanying consolidated balance sheets and related
consolidated statements of income, changes in partners' equity and of cash flows
present fairly, in all material respects, the financial position of Iroquois Gas
Transmission System, L.P. and its subsidiaries at December 31, 1998 and 1997,
and the results of their operations and their cash flows for each of the years
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 audits. We conducted our audits 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 audits provide a reasonable basis for the opinion expressed
above.

Iroquois Gas Transmission System

<PAGE>   7



                              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, NY to South Commack, Long Island, NY. 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.

     Subsequent to December 31, 1998, Alenco Iroquois Pipeline, Inc. sold its
interest in the Company to TCPL Northeast Ltd. 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%), TCPL Northeast Ltd. (6.0%), JMC-Iroquois, Inc. (4.93%), TEN Transmission
Company (4.87%), NJNR Pipeline Company (2.8%), and LILCO Energy Systems, Inc.
(1.0%). Iroquois Pipeline Operating Company, a wholly-owned subsidiary of
Iroquois, 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 $40.0 million and $55.0 million were made during 1998 and 1997, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
- --------------------------------------------------------------------------------
BASIS OF PRESENTATION

The consolidated 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 of Iroquois.
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 $27.4 million in 1998, consisting primarily of
low risk mutual funds, are carried at cost, which approximates market. At
December 31, 1998 and 1997, $11.0 million and $10.6 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
was depreciated over 25 years on a straight-line basis as a result of the rate
case settlement. Effective August 31, 1998 the depreciation rate was changed to
2.77% (36 years average life) in accordance with the FERC rate order issued July
29, 1998. The general plant is depreciated on a straight-line basis over five
years.

CONSTRUCTION WORK IN PROGRESS

At December 31, 1998, construction work in progress included on-going minor
capital projects. At December 31, 1997, construction work in progress included
construction costs relating to the Athens Compressor Station, which was placed
into service in November 1998.

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.


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, 1998, Iroquois was party to interest rate swap
transactions for aggregate notional principal amounts of $537.6 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 for Expansion Loan No. 2 expired November 2, 1998 at
which time the interest rate became 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 ($39.2) million
and ($29.1) million at December 31, 1998 and 1997, 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, 1998 the largest
single swap agreement subject to exposure was $13.1 million.

At December 31, 1998, the outstanding principal was $340.7 million on the base
loan, $12.9 million on Expansion Loan Agreement No. 1 and $11.7 million on
Expansion Loan No. 2 for total long-term debt of $365.4 million. The combined
schedule of repayments is as follows (in millions):

<TABLE>
<CAPTION>
     Year           Scheduled Repayment
     ----           -------------------
<S>                     <C>  
     1999                 $28.7
     2000                 $28.8
     2001                 $26.7
     2002                 $26.7
     2003                 $26.7
  Thereafter             $227.8
</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, 1998, the Company
had an outstanding letter of credit in the amount of $30.1 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 lendor's 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 1999. 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, 1998, Iroquois was providing multi-year firm reserved
transportation service to 34 shippers of 987.5 MDth/d of natural gas which
breaks down as follows:

<TABLE>
<CAPTION>

            Total                             987.5
</TABLE>

The long-term firm service gas transportation contracts expire between October
31, 2011 and August 1, 2018.

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 ("ALJ") to issue a decision in this proceeding by December 31, 1997.
Pursuant to that Suspension Order, the Presiding ALJ conducted a hearing on all
issues raised by Iroquois' filing, which was concluded on August 28, 1997.

     Following the December 31, 1997 issuance of the Initial Decision by the
Presiding ALJ, on January 30, 1998, Iroquois filed its brief on exceptions
vigorously opposing certain aspects of the Initial Decision. Briefs opposing
exceptions were filed by Iroquois and the other participants on February 27,
1998. On July 29, 1998, the Commission issued its "Order Affirming in Part and
Reversing in Part Initial Decision" ("July 29 Order"), which modified
significant portions of the Initial Decision. That July 29 Order provided, in
part, for a reduction in the depreciation rate from 4% to 2.77%; a reduction in
Iroquois' equity ratio from 35% to 31.85%; a reduction in the rate of return on
equity from the then-effective 15% to 12.38%; and the elimination of certain
discounts provided under certain long-term contracts. The net result of the
Commission's order was to reduce, prospectively, Iroquois' 100% load-factor
interzone rate (the rate charged for transportation along the entire length of
the Iroquois pipeline) from $0.65(1) per dth to $0.47(1) per dth. Iroquois' 
filing, in compliance with the July 29 Order, was accepted and the lower rates
became effective on August 31, 1998. In addition, on August 28, 1998 Iroquois
filed a request for rehearing of the July 29 Order, which (as well as a request
filed by other parties to the proceeding) is still pending.

     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 ALJ 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. Following oral argument on May 14, 1998, the
court on July 21, 1998 issued a decision reversing the Commission's December 20
and March 3 Orders and remanded the matter to the agency for further
proceedings. The court subsequently denied rehearing of its opinion on November
13, 1998 and issued its mandate. Iroquois had filed on August 13, 1998 to begin
recovering those legal defense costs; this filing was rejected by the Commission
on August 31 as premature. Iroquois subsequently (on January 14, 1999) filed a
motion with the Commission asking that the agency take action on the court's
remand of the issue; that motion is pending.

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, 1998, and 1997, Iroquois made payments of $0.9
million and $1.0 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):

<TABLE>

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, 1998 and 1997, the effective tax rate differs
from the Federal statutory rate due principally to the impact of state taxes.

9. RETIREMENT BENEFIT PLANS:
- --------------------------------------------------------------------------------
During 1997, the Company established a noncontributory 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 and 1998, the Company also adopted excess benefit plans (EBPs)
that provide retirement benefits to executive officers and other key management
staff. The EBPs recognize 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 EBPs are 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 consolidated balance sheets (thousands of dollars):

     The assumptions used in determining the pension obligation at December 31,
1998 and 1997 were:

Expected long-term rate of return                N/A
</TABLE>

The Company offers a defined contribution retirement plan with a 401(k)
provision to its employees working over 1,000 hours, with over one year of
service. The employees' contributions are matched, dollar for dollar, by
Iroquois, up to 5% of base pay. These costs are recognized on a monthly basis
and funding is made on a pay-as-you-go basis. The Company's matching
contributions to the 401(k) plan during 1998 and 1997 were $236.5 thousand and
$191.1 thousand, respectively. Iroquois does not provide post-retirement health
or life insurance benefits.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Partners of
The Latin America Energy and Electricity Fund I, L.P.:

We have audited the accompanying statements of assets, liabilities and partners'
capital, including the schedules of investments, of The Latin America Energy and
Electricity Fund I, L.P. (a Cayman Islands exempted limited partnership) as of
December 31, 1998 and 1997, and the related statements of operations, changes in
partners' capital and cash flows for the years then ended. These financial
statements are the responsibility of the Fund'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.

As explained in Note 2, the financial statements include securities valued at
$50,126,986 (96 percent of net assets) and $41,920,297 (97 percent of net
assets) as of December 31, 1998 and 1997, 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, 1998 and 1997, and the results of
its operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                          THE LATIN AMERICA ENERGY AND

                            ELECTRICITY FUND I, L.P.


                          NOTES TO FINANCIAL STATEMENTS

                           DECEMBER 31, 1998 AND 1997



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.

Cash and Cash Equivalents
- -------------------------

The Partnership considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.

<PAGE>   8
                                      -2-



Investment Risks
- ----------------

A significant portion of the Partnership's assets are invested in nonmarketable
securities. Because of the absence of any liquid trading market for these
investments, the Partnership may take longer to liquidate these positions than
would be the case for marketable securities. These securities may be resold in
privately negotiated or public sale transactions, and the prices realized on
such sales could be less than those originally paid by the Fund. Further,
companies whose securities are not marketable may not be subject to the
disclosure and other investor-protection requirements applicable to companies
whose securities are publicly traded. The value of nonmarketable securities,
totaling $50,126,986 (96 percent of net assets) and $41,920,297 (97 percent of
net assets) at December 31, 1998 and 1997, respectively, 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.

Additionally, a significant portion of the net assets of the Partnership is
invested in companies whose principal operations are located outside the United
States, including South and Central America. Such investments are subject to the
risks associated with, among other factors, the economic and political
environments of those countries, which can change rapidly and have a significant
impact on the ability of the Partnership to realize the value of its
investments.

Investment Valuation
- --------------------

Unquoted securities are stated at their estimated fair value at December 31,
1998 and 1997, as determined by the Fund Manager.

Investment Transactions
- -----------------------

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

During 1998, the Partnership realized a net gain from the partial sale of
Ontario-Quinta which had a cost basis of approximately $2,516,000. This sale
generated net proceeds of approximately $3,573,000 and a net realized gain of
approximately $1,057,000.

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 statements of assets, liabilities
and partners' capital and totaled $382,953 as of December 31, 1997. No such
costs are capitalized as of December 31, 1998. 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.


<PAGE>   9
                                      -3-



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
- ---------------------

Capital contributions were $60,303,030 and $44,403,057 at December 31, 1998 and
1997, respectively, net of capital drawn for unconsummated investments
subsequently returned and capital drawn by the admission of additional limited
partners and reimbursed to the original limited partners. Total capital
commitments of the partners were fully drawn in the amount of $60,303,030.

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.

During 1998, the distributions to General Partner and Limited Partners
represented distributions of earnings on investments as well as a return of
invested capital and proceeds from the partial sale of an asset. During 1997,
the distributions to the 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 

<PAGE>   10
                                      -4-




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.

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, 1998 and 1997, 96% and 97%
of the Fund's net assets, respectively, were invested in such securities.

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. Under the terms of the Shareholders Agreement of
Ontario-Quinta, in August of 1999, Ontario-Quinta will liquidate itself and
distribute the pro rata holdings of Luz del Sur and TechnoSur to each
Ontario-Quinta shareholder.

In January 1998, the Fund sold 43% of its investment in Ontario-Quinta for
$3,573,005, or $1.68 per share. At December 31, 1998, the asset was valued at
the underlying publicly traded pro rata market value of Luz del Sur and
TechnoSur, an aggregate of $2,672,086 or $0.93 per Ontario-Quinta share. In
1997, the investment was valued at the January 1998 sales price of $1.68 per
share.

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, 1998 and 1997, the
investment was valued at cost. The valuations were based on, among other
factors, the consideration that the shares are not publicly traded, transactions
that have occurred between other shareholders have been consummated at prices
above the current cost for the Fund, and no other matters have come to the
attention of the Fund Manager 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 e Luz
Cataguazes-Leopoldina ("Cataguazes"), a Brazilian energy and utility company.
The Fund paid $20,860,036 for preferred and common shares and capitalized
$440,577 of costs involved in consummating the investment. During 1998, the Fund
invested an additional $1,986,101 to purchase 1,092,500,000 preferred shares.
The investment was carried at cost at December 31, 1998 and 1997. The average
cost per share of the investment is $2.68 (per 1,000 shares) and the Fund's
investment represents approximately 5.99% of the common voting shares of
Cataguazes and 7.37% of the preferred nonvoting shares as of December 31, 1998.
At the time of this investment, the Fund and an affiliated 


<PAGE>   11
                                      -5-



fund entered into a Shareholders Agreement with the other main shareholders of
Cataguazes, whereby the Fund may unilaterally exercise a significant number of
control provisions over the affairs of Cataguazes; in addition, the Fund and the
affiliated fund nominated a Director to the Board.

Although Cataguazes is publicly traded on Brazilian stock exchanges, it is
traded infrequently. As such, based on the significance of the holdings of the
Fund, the investment is currently considered nonmarketable. The determination to
value the investment at cost was based on, among other factors, the
consideration that the shares are infrequently traded and that the public market
price, in any event, does not represent a price at which the control provisions
exercised by the Fund would be valued; no transactions have occurred between
other shareholders; the Fund Manager's belief that the present value of the
investment is significantly in excess of cost; and no other matters have come to
the attention of the Fund Manager that would create a better estimate of current
value than the original cost. In its calculation of the present value, the Fund
Manager considered, among many factors, the financial results of Cataguazes for
the year ended December 31, 1998, the January 1999 devaluation of the Brazilian
Real, continued high interest rates in Brazil, an increase in Brazilian
inflation as a result of the devaluation, a potential slowdown in the growth
rate of electricity sales, and the future prospects of Cataguazes, including the
expected evolution of electricity tariffs in response to recent events.

Transredes S.A.
- ---------------

In two transactions in July 1998 and December 1998, the Fund purchased 302,736
common shares of Transredes S.A. ("Transredes") for $11,948,502, including
capitalized expenses of $943,501, or a total cost of $39.47 per share.
Transredes is a Bolivian pipeline and petroleum products transportation company
which was privatized in May 1997 at a price of $52.00 per share. As of December
31, 1998, the investment was carried at cost. The investment represents
approximately 3% of the outstanding common shares.

<PAGE>   12
                                      -6-



Transredes is currently owned by Bolivian pension funds, current and former
workers, Enron Corp. and Shell Oil Company. The shares are not listed on any
exchange, although listing is anticipated within the next few years. The 1998
valuation was based on, among other factors, the consideration that the shares
are not publicly traded, few transactions have occurred among other shareholders
and no other matters have come to the attention of the Fund Manager that would
create a better estimate of current value than the original cost.

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, 1998 and 1997, the balance
outstanding under this note was $223,878 and $246,716, 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, 1998 and 1997, advisory fees of $125,000
have been paid to the Regional Advisor and are included in administrative
expenses in the statements of operations. The Advisory Agreement was terminated
as of January 1, 1999.

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 advisory agreement at the end of the third quarter of 1997. For the
year ended December 31, 1997, financial advisory fees of $113,068 were recorded
in the statements of operations. For the year ended December 31, 1998, no
financial advisory fees were incurred by the Fund.

                                      -7-



Technical Advisor
- -----------------

The Fund has entered into a technical advisory agreement with a limited partner

- -------------------

In 1998 and 1997, the Fund Manager incurred certain administrative costs on
behalf of the Fund. At December 31, 1998 and 1997, amounts remaining to be
reimbursed to the Fund Manager were $237,367 and $134,447, respectively.

           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 August 31, 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.

                           Having concluded the five-year mandatory investment
                           plan and other investments made in order to adapt the
                           safety and reliability of the system to international
                           standards, the Subsidiary Company has conducted a
                           review of the useful lives based upon the inventory
                           as of December 31, 1997. To such effects, independent
                           technical experts were hired in order to evaluate the
                           condition of the assets used in the provision of gas
                           distribution services. The impact of the extension of
                           the useful life upon the net profit for the 1998
                           fiscal year amounts to approximately Ps. 2.1 million.

                           The Subsidiary Company defers the net costs derived
                           from the financing with third party capitals of

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

                  g.       Intangible assets

                           This caption includes the acquisition of software and
                           expenses in relation to the programs for the issuance
                           of the Notes by Sodigas Sur S.A. and its Subsidiary
                           Company, to be amortized over a five-year period.

                           Intangible assets added 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.

                  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.

                  i.       Profit/(loss) accounts

                           Profit/(loss) for the year is disclosed at historical
                           values, except for the charges for assets consumed
                           (fixed asset depreciation and intangible asset
                           amortization), which were determined according to the
                           values of such assets.

                  j.       Accounting recognition of income

                           The income stemming from gas distribution activities
                           is recognized when the service is rendered and
                           charged to the "Unbilled gas consumption" account.

                  k.       Statement of Cash Flows

                           The Consolidated Statement of Cash Flows is presented
                           using the Indirect Method of Alternative D of
                           Technical Resolution No. 9 of the Argentine
                           Federation of Professional Councils of Economic
                           Sciences, considering Cash and Banks and Short-Term
                           Investments as funds.

                  l.       Accounting estimates

                           The preparation of these financial statements as of a
                           specified date requires that the Subsidiary Company's
                           management performs estimates and assessments that
                           affect the amount of the recorded assets and
                           liabilities and the contingent assets and liabilities
                           disclosed as of the date of these financial
                           statements, as well as the income and expenses
                           recorded during the fiscal year. The Subsidiary
                           Company's management makes estimates so as to
                           calculate, among other things, the income tax charge,
                           the unbilled gas consumptions, the discounts to be
                           made to users and the provisions for contingencies,
                           as of a certain date. The actual future results may
                           differ from the estimates and assessments made as of
                           the date of the financial statements.

NOTE 7:           ISSUANCE OF NOTES BY THE SUBSIDIARY COMPANY

                  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).

                  issuance of Notes are the following:

                           person, unless the Notes are equally and ratably
                           secured by such liens, except for:

                  case may be, of the property subject to such agreement.

                  corresponding mainly to the attachments levied by several
                  municipalities in connection with the lawsuits related to

                  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 Company completed the transfer of
                  all the vehicles.

NOTE 10:          LEGAL AND TAX MATTERS

                  a.       Income tax

                  On January 30, 1998 and May 28, 1998, the Subsidiary Company
                  amended the tax returns, paying the difference generated by
                  the deduction of the tax on assets and amending the
                  depreciation of fixed assets received free of charge as a
                  consequence of the new tax determination of the amounts
                  corresponding to networks added by the Company as of June
                  1995, by application of the ENARGAS's Resolutions governing
                  the transfer of networks funded, in whole or in part, by third
                  parties.

                  On June 22, 1998, the Argentine Tax Authority ("AFIP") gave
                  notice of the adjustments proposed by the inspections which
                  amount to Ps. 1,282,185 for the deduction of the tax on assets
                  applicable in 1993 and 1994, and to Ps. 11,759,623
                  corresponding to computation differences originated in the
                  treatment as non-assessable income granted by the Subsidiary
                  Company to the networks received free of charge during 1993,
                  1994 and 1995, which was answered on July 14, 1998.

                  Furthermore, on August 23, 1998, a copy of the amended tax
                  returns requested by the Division Determinacion de Oficio of
                  the AFIP was attached to the answer.

                  Said amendments were not considered by the AFIP at the time of
                  serving the notice.

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

                  On January 15, 1999, an order from the Division Determinacion
                  de Oficio (Official Assessment Division) was received,
                  requesting the Division Fiscalizadora Externa II (External
                  Control Division II) to attach within a 30-business day term,
                  a technical report as regards the different aspects included
                  in the Subsidiary Company's answer. As of the date hereof, the
                  Subsidiary Company is preparing the answer to the requirement
                  made by the Division Fiscalizadora Externa II.

                  In the opinion of the Subsidiary Company and its legal
                  counsel, the filing of the amended tax returns applying the
                  criteria of the ENARGAS for tax purposes, and the inclusion of
                  the adjusted amounts in the Installment Payment System
                  (Regimen de Facilidades de Pago) would settle the matter,
                  since the interests of the Tax Authority would be satisfied,
                  and therefore any attempt by it to re-open the case would not
                  be successful.

                  b.       Municipal taxes

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

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

                  Point 6.1 of the License reads as follows: "while the licensee
                  is in charge of the service, the licensee 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 the use of subjacent rights upon the Company, the licensee
                  Company may pass through such additional cost to consumers
                  residing within the jurisdiction in which such tax is
                  applicable, and the Regulatory Entity shall act in accordance
                  with the procedures described in point 9.6.2, without any
                  right of claim against the Company or Gas del Estado".

                  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 Ps. 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 Subsidiary Company finally filed an appeal before
                  the Argentine Supreme Court of Justice requesting that the
                  appeal dismissed by the trial court be sustained, which motion
                  is currently pending resolution. The National Supreme Court
                  requested the main file from Viedma, thus admitting it is
                  dealing with the appeal for nullification. The judicial
                  deposits made during the year 1996 for an aggregate amount of
                  Ps. 263,362, are maintained plus Ps. 62,720 in respect of
                  interest and legal costs. The Subsidiary Company has set up a
                  provision for the aggregate amount claimed.

                  In addition, the Municipality has brought an action against
                  Camuzzi Gas del Sur S.A. for Ps. 148,148 in respect of
                  principal corresponding to the payment of the tax on subsoil
                  rights due for the year 1995.

                  The Subsidiary Company has contested the proceeding. The
                  Municipality has answered the plea. Judgment was pronounced
                  against the Subsidiary Company which has therefore filed an
                  appeal; the appeal was sustained and the Subsidiary Company
                  submitted the briefs of the case. The Court of Appeals
                  confirmed the first instance judgment and the Subsidiary
                  Company filed an appeal for nullification. The Supreme Court
                  of Justice of the Province sustained such appeal only as far
                  as it relates to a motion based on the jurisdiction of the
                  court.

                  In connection with the other prejudices caused by the
                  judgement of the Court, Camuzzi Gas del Sur S.A. filed an
                  extraordinary motion with the Federal courts against such
                  decision.

                  The Licensee set up a provision of Ps. 95,545, which is
                  included under the item "Provisions".

                  Municipality of Neuquen: The amount claimed totals Ps. 66,524,
                  not including penalties and other expenses. The Municipality
                  appealed the decision of the Court of Appeals, on the grounds
                  of lack of jurisdiction of the provincial court


<PAGE>   18


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

                  to hear the case. The lack of jurisdiction 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 judgment. The Court of Appeals
                  rejected the motion filed by the Subsidiary Company and a
                  motion for lack of jurisdiction was filed with the Supreme
                  Court of Justice of the Province, and was rejected. The
                  plaintiff filed a table describing the debt service, including
                  payment of principal, interest and court fees, for an amount
                  of Ps. 150,746. The plaintiff's counsel continues taking the
                  steps to judicially collect the debt.

                  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 made a new claim for the period
                  April 1996 - May 1997 for an amount of Ps. 97,421, without
                  including interest and penalties. The claim was answered by
                  means of a letter document whereby the Subsidiary Company was
                  required to abandon the claim for payment under the warning of
                  having the subsidies suspended. As of December 31, 1998, Ps.
                  99,774 have been deposited with the court. The Municipality
                  decided to suspend any further proceeding until the Supreme
                  Court of Justice of the Province decides the case of the
                  Licensee Company against said Municipality in connection with
                  taxes imposed on the occupancy of public places. The
                  Subsidiary Company has set up a provision for the aggregate
                  amount claimed, and included it in the "Provisions" caption.

                  Municipality of Comodoro Rivadavia: The Municipality has
                  claimed against Camuzzi Gas del Sur S.A. the payment of taxes
                  on rights to public space which amount to a principal amount
                  of Ps. 56,032. The claim is currently pending with the
                  Administrative Court upon discharge filed by the Subsidiary
                  Company.

                  Municipality of Zapala: the amount claimed totals a principal
                  amount of Ps. 816,073 corresponding to the periods between
                  1993, 1994, 1995 and January to November 1996. The Subsidiary
                  Company has filed a motion for reconsidering such claim.

                  Municipality of Villa Regina: the amount claimed totals the
                  principal amount Ps. 1,939,343, not including penalties and
                  other expenses; the Subsidiary Company has filed the relevant
                  administrative answer.

                  Municipality of Cutral-Co: the Municipality filed a claim for
                  the payment of Ps. 133,992, in respect of taxes on rights to
                  public space as from January 1993 through October 1996, net of
                  interest and legal costs. Camuzzi Gas del Sur S.A. contested
                  the proceeding. The judgment entered by the first instance
                  court rejected the motions and the Company appealed such
                  judgment and submitted the briefs of the case. The judgment
                  entered by the Court of Appeals confirmed the previous
                  judgment, and, consequently, an extraordinary motion has been
                  filed. The Subsidiary Company set up a provision of Ps.
                  71,296, which is included in the "Provisions" caption.

                  Municipality of Piedra del Aguila: the amount claimed totals
                  Ps. 1,900. The Subsidiary Company filed a motion for
                  reconsidering such claim.

                  In the opinion of the Subsidiary Company, 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.

                  c.       Gross sales tax

                  c.1      Camuzzi Gas del Sur S.A. has received several claims
                           from some provincial tax authorities regarding the
                           taxability of income deriving from subsidies, in
                           connection with Gross Income Tax. As of December 31,
                           1998, the maximum estimated principal amount of gross
                           income tax, would total approximately Ps. 10.4
                           million, assuming that all the provinces involved
                           decide to make a claim.

                           In the opinion of the Subsidiary Company and its
                           legal counsels, there are no grounds for this claim
                           as the subsidy is not subject to provincial taxes
                           since it was granted by the National Government.

                           The following claims have been received up to the
                           date hereof in connection with this item:

                           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

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                           from 1993, 1994, 1995 through March, 1996, claiming
                           differences in favor of the State amounting to Ps.
                           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 Ps. 28,892, for the period January-March
                           1993. As of the date hereof, the amount claimed was
                           deposited with the Court.

                           The Subsidiary Company is currently preparing the
                           initial brief in order to file it with the courts.

                           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 Ps. 962,748, in respect
                           of principal, of which approximately Ps. 596,000
                           correspond to Gross Income tax on subsidies for the
                           period from 1993 to June 1996. Furthermore, the
                           Ministry of Economy and Public Works and Services
                           rejected the appeal against the Resolution issued 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, which was rejected. The Subsidiary Company
                           filed a claim as regards the Gross Income Tax on
                           subsidies, for the period from January 1993 to June
                           1996 for the amount of Ps. 897,608, of which Ps.
                           595,919 correspond to the tax amount and Ps. 301,689,
                           to interest thereon, in order to file such claim the
                           amounts claimed were paid, with the aim to obtain the
                           reimbursement thereof.

                           Province of Santa Cruz: The final inspection report
                           has been submitted assessing Ps. 1,209,457 for gross
                           income tax on subsidies, not including interest and
                           penalties.

                           On September 25, 1998, an appeal to reconsider the
                           judgement was filed to oppose Regulation No. 860/98
                           whereby the settlement carried out by the inspection
                           was approved.

                           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
                           Ps. 1,078,484, not including interests and penalties.
                           The Subsidiary Company has duly filed the applicable
                           answer.

                           Province of Rio Negro: Camuzzi Gas del Sur filed an
                           answer to a notice for the beginning of summary
                           proceeding made by the General Revenue Board of the
                           Province of Rio Negro, questioning the gross sales
                           tax returns for the years 1993 to 1995 through August
                           1996, claiming differences in favor of the Tax
                           Authority amounting to Ps. 2,691,781, of which
                           approximately Ps. 1,091,000 correspond to the claim
                           related to the tax on income deriving from subsidies,
                           not including interest or penalties.

                           As regards the period from January 1993 to February
                           1996, a tax collection proceeding was filed against
                           the Subsidiary Company for Ps. 3,250,539 for the
                           principal outstanding, which includes the tax owed
                           due to a difference in the tax basis described in
                           item c.2. The licensee answered the complaint
                           mentioning the State as a third party to the
                           proceeding, but this was rejected by the court of
                           first instance. The Subsidiary Company filed an
                           appeal with the same court requesting the revocation
                           of such resolution. The judge of first instance
                           issued a judgment favorable to the Revenue Board and
                           levied an attachment of up to Ps. 4,509,392, in
                           relation to the claim for gross income tax on
                           subsidies and the difference in the tax base
                           described in item c.2. as well as interest and court
                           fees. In return the Subsidiary filed an appeal with
                           the Court of Appeals, which appeal was rejected. In
                           return, the Subsidiary Company filed an appeal for
                           nullification before the Supreme Court of the
                           Province. The Province has withdrawn from the
                           attachment the amount in respect of principal, in
                           spite of the express opposition by the Subsidiary
                           Company. Subsequently, the Court denied the appeal
                           for nullification and so the Licensee filed an appeal
                           for the rejection of the nullification before the
                           Supreme Court of the Province of Rio Negro.

                           Thereafter, on November 12, 1998, the General Revenue
                           Board of the Province of Rio Negro notified the
                           Subsidiary Company as regards Resolution No. 093/98,
                           establishing a fine of Ps. 2,060,205, as a penalty
                           for the non-payment of the Gross Income Tax on
                           subsidies and the method for calculating the tax
                           basis. The Subsidiary Company filed on appeal for
                           reconsideration which was rejected on February 16,
                           1999. On March 4, 1999, the Subsidiary Company filed
                           an administrative appeal against such resolution.

                           On November 17, 1998, the General Revenue Board of
                           the Province of Rio Negro notified the Subsidiary
                           Company of Resolution No. 090/98, claiming an amount
                           of Ps. 890, 997 in respect of Income Tax on subsidies

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

                           for the period from September 1996 to December 1997
                           and for the tax basis for the period from September
                           1996 to December 1996, plus a fine of Ps. 1,251,580,
                           for the non-payment of such items; thereafter, the
                           Company filed a reconsideration.

                           For the periods March 1996 to June 1996 and July 1996
                           to August 1996, the Subsidiary Company also filed
                           reconsiderations against the resolutions of the
                           General Revenue Board of the Province of Rio Negro.
                           On January 6, 1999, the Subsidiary Company was
                           notified of resolution 1355/98, rejecting the
                           reconsideration filed against Resolution No. 007/98,
                           setting forth an amount due of Ps. 313,916, in
                           respect of basis on the Gross Income Tax on subsidies
                           and calculation of the tax basis of the period from
                           March to June 1996, of which approximately Ps.
                           116,000 correspond to the claim for Gross Income Tax
                           on subsidies. Furthermore, the Subsidiary Company was
                           notified of Resolution No. 1356/98, of the same tenor
                           of the previous one, for Ps. 317,660, for the period
                           from July to August 1996, of which approximately Ps.
                           152,000 correspond to the claim for Gross Income Tax
                           on subsidies; the Subsidiary Company filed
                           administrative appeals.

                  c.2      Camuzzi Gas del Sur S.A. received several tax
                           assessments issued by the tax authorities of the
                           Province of Buenos Aires and the Province of Rio
                           Negro related to differences in the determination of
                           the tax base of Gross Income Tax. Such difference
                           arises mainly from the fact that the tax authorities
                           claim that the tax basis on which the tax rate is
                           applied for computing gross sales taxes on gas sales
                           includes all revenue obtained whereas the Subsidiary
                           Company's position, since the beginning of
                           operations, has been that the tax base is the
                           difference between the gas selling and purchasing
                           prices.

                           Below, there is a description of the situation with
                           each of the provinces involved:

                           Province of Buenos Aires: The Province of Buenos
                           Aires Revenue Board (the "DPRPBA") made assessments
                           questioning the Company's Gross Sales Tax returns,
                           and claiming Ps. 27,027 and Ps. 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.

                           On November 25, 1996, the General Revenue Board
                           issued a Final Opinion stating that, in its opinion,
                           Camuzzi Gas del Sur S.A. must pay gross sales tax on
                           its total sales and not on the distribution margin.
                           On December 13, 1996, the General Revenue Board
                           further explained some points of the opinion
                           indicating that, according to such body's
                           interpretation, 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 in 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 No. 11,808. (Official Gazette July 10, 1996).

                           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 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 No. 24,076.

                           Through Resolution No. 544 dated November 17, 1997
                           and pursuant to the regulatory framework of the
                           activity, the ENARGAS 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, which is
                           immaterial, related to the effect on the sales to
                           subdistributors and CNG stations is still pending.

                           Therefore, and as mentioned before, because a "change
                           in 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 del Sur S.A. accounted
                           for the amounts recognized as tax payable, together
                           with the

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                           payments made for the tax base 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.

                           At December 31, 1998, the receivable to be recovered
                           (which includes the amounts accrued during the first
                           semester of 1998) amounts to Ps. 108,201, of which,
                           Ps. 24,191 were recorded under "Other Current
                           Accounts Receivable" and Ps. 84,010 under "Other
                           Non-Current Accounts Receivable".

                           Province of Rio Negro: Provincial Law No. 3069,
                           promulgated by Decree No. 2198/96 dated December 30,
                           1996, amended the Tax Code by abrogating item (d) of
                           section 12 of Law No. 1301; according to the
                           interpretation of the Subsidiary Company and its
                           legal counsels, the tax base of the tax was formed by
                           the difference between the purchasing and selling
                           prices. Consequently, on April 14, 1998, the
                           Subsidiary Company paid Ps. 682,364 in respect of the
                           tax difference derived from the change in the tax
                           base for the January 1997 - February 1998 period.

                           Therefore, and as a "change in the tax rules"
                           generates a right for the Subsidiary 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 del Sur S.A. accounted
                           for the amounts recognized as a tax increase for the
                           period from January 1997 to February 1998, as well as
                           the tax increase accrued thereafter, considering the
                           tax base 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.

                           As of December 31, 1998, the receivables to be
                           recovered amount to Ps. 819,588, and has been
                           recorded under "Other Non-current Accounts
                           Receivable".

                           Furthermore, as mentioned in item c.1., the
                           provincial tax authority claimed Ps. 2,691,781,
                           including the Gross Revenue Tax on Subsidies, and
                           differences in the tax basis. The amount claimed for
                           differences in the tax basis totals approximately Ps.
                           1,601,000 and corresponds to the period from January
                           1993 through August 1996, which is prior to the
                           amendment of the Tax Code.

                           As mentioned in item c.1., the amounts related to
                           this claim are subject to an attachment levied by the
                           Provincial Revenue Board.

                           As regards the periods from March 1996 to June 1996
                           and July 1996 to August 1996, the amounts of the
                           claims as regards Gross Income Tax on tax basis are
                           approximately Ps. 198,000 and Ps. 165,000,
                           respectively, and the comments included in item c.1
                           for these periods are applicable hereto.

                           The same comments included in item c.1 are applicable
                           for the period from September 1996 to December 1997,
                           the amount of the claim as regards the tax basis
                           being estimated at Ps. 241,000 only for the period
                           from September 1996 to December 1996 (see first and
                           second paragraphs of this note).

                           In order to pass through this higher cost and
                           according to the legitimate right of the Subsidiary
                           Company, measures are being taken before the
                           Regulatory Authority to apply the relevant tariff
                           adjustment.

                           In the opinion of the Subsidiary Company and its
                           legal counsels, an adverse decision in relation to
                           the passing-through of such higher costs due to Gross
                           Revenue Tax is considered not probable. .

                  c.3      The Subsidiary Company accepted the claim of the
                           Province of Tierra del Fuego as regards differences
                           in the determination of the tax basis corresponding
                           to the tax on sales to industrial users ("0" rate),
                           entailing the payment of the Ps. 864,213, as regards
                           tax plus Ps. 233,543 in respect of interest,
                           totalling Ps. 1,097,756.

                           The Subsidiary Company set up a provision of Ps.
                           1,087,472 which includes all principal and interest
                           accrued as of December 31, 1998.

                  d.       Stamp tax

                           Regards stamp tax the situation is as follows:

                  d.1      Province of Rio Negro: The Subsidiary Company 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.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                  d.2      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,
                           Antartida and South Atlantic Islands, claiming the
                           assessment of stamp tax under a Decree of the
                           Executive Power, amounting to Ps. 140,000, not
                           including interest or penalties.

                  d.3      Province of Neuquen:

                           d.3.1    The Revenue Board of the Province of Neuquen
                                    submitted a liquidation of the Stamp Tax on
                                    the gas purchase agreements entered into
                                    together with Camuzzi Gas Pampeana S.A., for
                                    an amount of Ps. 1,656,205. Subsequently,
                                    the Revenue Board of the Province of Neuquen
                                    notified an amended amount of the
                                    computation performed by the supervisors for
                                    the amount of Ps. 10,400,134. The notice was
                                    answered and the resolution was interrupted
                                    on account of the moratorium decrees.
                                    Subsequently, notes were filed with the
                                    Argentine Ministry of Economy requesting an
                                    opinion from the Minister. The province
                                    issued a Special Decree No. 3534 for the
                                    regulated companies to avail themselves of
                                    the moratorium; the time to do so expired on
                                    November 6, 1998, and was renewed until
                                    January 11, 1999.

                                    As of December 31, 1998, the Subsidiary
                                    Company recorded an allowance of Ps. 597,548
                                    in this respect.

                                    On January 7, 1999, the ENARGAS submitted a
                                    report to the Argentine Ministry of Economy,
                                    expressing that "the taxes claimed by
                                    Neuquen, shall unfailingly lead to in a
                                    tariff increase, with a serious damage for
                                    the users". The expiration occurred on
                                    January 11, 1999 has not been renewed. The
                                    Licensee Company is waiting for an opinion
                                    from the Ministry of Economy as regards this
                                    issue.

                           d.3.2    Additionally, the Revenue Board has made an
                                    assessment for a total amount of Ps.
                                    1,827,518 of stamp tax on the transfer of
                                    assets affected to the service. This claim
                                    was filed jointly against Gas del Estado and
                                    the Subsidiary Company. Camuzzi Gas del Sur
                                    S.A. has filed the applicable answer.

                           d.3.3    Finally, the Province of Neuquen's Revenue
                                    Board has served notice to the Subsidiary
                                    Company claiming a principal amount of
                                    approximately Ps. 0.7 million. This amount
                                    corresponds to the stamp tax derived from
                                    the transport agreements entered into with
                                    Transportadora de Gas del Sur S.A., before
                                    take over when Gas del Estado S.E. was the
                                    only shareholder of the Company. The Company
                                    notified its position to Gas del Estado S.E.

                                    Camuzzi Gas del Sur S.A. believes that these
                                    agreements were not subject to provincial
                                    stamp tax due to the fact that the parties
                                    who entered into said agreements were
                                    Argentine state-owned companies, owing to
                                    the fact that the State is exempted from
                                    such tax. Even though such agreements were
                                    subject to stamp tax, the Company considers
                                    that Gas del Estado S.E. would be the party
                                    liable for the payment of this tax, in
                                    accordance with the provisions of the
                                    Transfer Agreement.

                                    In the opinion of the Subsidiary Company and
                                    its legal counsels, except for what is
                                    mentioned in item d.3.1, an unfavorable
                                    resolution with respect to such claims is
                                    not considered probable.

                  e.       Safety and health tax

                           The Municipality of Rio Colorado claimed the payment
                           of Ps. 132,225 as Safety and Health Tax, not
                           including interest and court fees. The Subsidiary
                           Company answered the claim from the Municipality.
                           Subsequently, a judgment was entered into admitting
                           the claim of the Municipality. Finally, on December
                           22, 1998, an Agreement was entered into with the
                           Municipality for an amount of Ps. 75,515, which was
                           paid fully in December 1998.

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

                  f.       Regulatory aspects

                           On March 24, 1998, the ENARGAS, through resolution
                           588/98, requested Camuzzi Gas del Sur S.A. to
                           reimburse approximately Ps. 4.5 million to the users
                           as regards "non-compliance with the gas quality set
                           forth by the License and Resolution 113/94, in the
                           terms of Chapter X of the License", for the period
                           from January 1996 to March 1997. The term and the
                           proceedings used by the Regulatory Authority for the
                           determination of the amount were objected by the
                           Subsidiary Company with the Secretariat of Energy.

                           Furthermore, on January 7, 1999, the Secretariat of
                           Energy issued a preliminary technical judgement,
                           whereby it construes that the requirements of the
                           ENARGAS are to be applied for the period from
                           September 1996 to March 1997. In accordance with the
                           foregoing, the Subsidiary Company made a provision of
                           approximately Ps. 0.9 million, calculated in
                           accordance with the methodology set forth in such
                           preliminary judgement.

                           As of the date hereof, the issue of the definitive
                           judgment by such entity is pending.

                           In the opinion of the Subsidiary Company and its
                           legal counsel the allowance made is sufficient to
                           cover such claim.

                  g.       Others

                           g.1      On August 8, 1998, the Ministry of Economy
                                    and Public Works and Services filed a claim
                                    for Ps. 656,485 for differences in the
                                    collection of overdue bills; Camuzzi Gas del
                                    Sur S.A. was in charge of managing their
                                    collection for the account of Gas del Estado
                                    S.E., pursuant to Schedule XXI of the Share
                                    Transfer Agreement.

                                    The Subsidiary Company duly set up an
                                    allowance to meet the claim for Ps. 175,000,
                                    which is considered sufficient.

NOTE 11:          SUBSIDIARY'S ESSENTIAL ASSETS INVENTORY

                  In compliance with ENARGAS' Resolution No. 60, the Subsidiary
                  Company made an inventory of the assets essential for the
                  service as of December 31, 1997. Such inventory was certified
                  by an independent expert specialized in that field on October
                  26, 1998.

                  As a result of said work, differences were detected between
                  the accounting inventory and the physical one, which reduce
                  the assets previously recorded in an amount of approximately
                  Ps. 5.5 million.

                  Due to the fact that the Subsidiary Company carries a
                  voluntary reserve consisting of earnings from gas distribution
                  networks financed by third parties and transferred free of
                  charge, the Subsidiary Company adjusted the aforementioned
                  differences against the voluntary reserve.

NOTE 12:          CONSTRUCTION FUNDED BY THIRD PARTIES

                  Constructions funded by third parties, incorporated into the
                  Subsidiary Company's network during the fiscal years ended
                  December 31, 1998 and 1997, were the following:

                  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.

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

                  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, as regards networks
                  transferred without monetary consideration, during the 1996
                  fiscal year, the Subsidiary Company recorded a liability in an
                  amount estimated as the payment price in cubic meters of gas,
                  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. 587, dated March 16, 1998, whereby it established the
                  consideration to be given to the users in accordance with the
                  methodological guidelines included therein.

                  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 appealed by the
                  Subsidiary Company on the grounds that it affects its
                  legitimate rights. However, the Subsidiary Company made an
                  analysis to determine the amount to be discounted in
                  compliance with such order. As a result of such work, it was
                  established that in the event that the existing users and the
                  potential users to be included in the assets transferred to
                  the Subsidiary Company without monetary compensation are
                  entitled to the discounts set forth in the ENARGAS'
                  resolutions, the increase in the liabilities would amount to a
                  maximum of Ps. 7.6 million.

                  In addition, it should be noted that such liability may be
                  substantially lesser due to the fact that as of the date of
                  the financial statements the number of users entitled to such
                  discount cannot be determined, and so the liability shall be
                  acknowledge to the extent that the amount to be paid to users
                  is agreed with them.

                  Considering that the Subsidiary Company accountably keeps a
                  voluntary reserve which includes the new undertakings financed
                  by third party users and transferred free of charge, such
                  adjustment, if applicable, will be accounted as a withdrawal
                  from such reserve, in which case, the final balance thereof
                  would amount approximately to Ps. 13.5 million.

                  As regards the networks transferred for a valuable
                  consideration, the liability shall also be acknowledged to the
                  extent that the amount to be paid to users is agreed with
                  them.

NOTE 13:          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 sub-area; such values will be
                  applicable during the 1998-2002 five-year period.

                  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.

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

                  During 1997, 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
                  1997 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 Cordilleran
                  subarea with a K factor related to support works in the
                  respective pipeline.

                  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 14:          INFORMATION SYSTEMS ADAPTATION PROCESS (UNAUDITED)

                  The Subsidiary Company began a process to update its
                  information systems and related technologies, which has been
                  given priority by the Board of Directors. The methodology of
                  work adopted allocates to different engagement teams the
                  finding of a solution for the administrative, invoicing, human
                  resources, hardware and software systems.

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

              For the Fiscal Years Ended December 31, 1998 and 1997


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,
                  1998 and 1997, 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 Company.

                  Non-monetary items included in the Financial Statements at
                  December 31, 1998 and 1997, have been restated in current
                  Pesos up to August 31, 1995. No adjustments have been applied
                  since such date.

                  The information at December 31, 1997, has been reclassified,
                  for comparative purposes, to be consistent with that of the
                  current year.

                  The December 31, 1998 financial statements of the Subsidiary
                  Company, Camuzzi Gas Pampeana S.A., which cover the same
                  period 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 Company 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, 1998 and 1997, are as follows:

                  a.       Local currency assets and liabilities
                           -------------------------------------

                           The local currency assets and liabilities have been
                           stated at their face value at the balance sheet date,
                           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.

                  c.       Current investments
                           -------------------

                           These are the following:

                           -        Shares and participation in investment funds

                           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 year; the value thereof does not
                           exceed their recoverable value.

                  f.       Other assets
                           ------------

                           This item includes a fixed-term deposit with
                           Mercobank S.A. maturing on 2001, as well as Class C

                           the Financial Statements. Such assets were valued at
                           their estimated recovery value.

                  g.       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 August 31, 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
                           Subsidiary 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.

                           Having concluded the five-year mandatory investment
                           plan and other investments made in order to adapt the
                           safety and reliability of the system to international
                           standards, the Subsidiary Company has conducted a
                           review of the useful lives based upon the inventory
                           as of December 31, 1997. To such effects, independent
                           technical experts were hired in order to evaluate the
                           condition of the assets used in the provision of gas
                           distribution services. The impact of the extension of
                           the useful life upon the net profit for the 1998
                           fiscal year amounts to approximately Ps. 2.3 million.

                           The Subsidiary Company defers the net costs derived
                           from the financing with third party capitals of
                           construction works which extends in time until they
                           are in start-up conditions. The amount capitalized in
                           fixed assets amounted to Ps. 633,608 during the
                           fiscal year ended December 31, 1998.

                           The preparation of these financial statements as of a
                           specified date requires that the Subsidiary Company's
                           management performs estimates and assessments that
                           affect the amount of the recorded assets and

                           disclosed as of the date of these financial
                           statements, as well as the income and expenses
                           recorded during the fiscal year. The Subsidiary
                           Company's management makes estimates so as to
                           calculate, among other things, the income tax charge,
                           the unbilled gas consumptions, the discounts to be
                           made to users and the provisions for contingencies,
                           as of a certain date. The actual future results may
                           differ from the estimates and assessments made as of
                           the date of the financial statements.

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

                  (1)      On March 26, 1998, Loma Negra C.I.A.S.A. sold its
                           interest in Sodigas Pampeana S.A.

                  (2)      Central Piedrabuena S.A. made payments under protest
                           for approximately Ps. 2.0 million and additionally,
                           it has not recorded approximately Ps. 1.9 million,
                           which was originated by differences in the
                           construction of gas purchase agreement currently in
                           force. As of the date hereof, the dispute has been
                           submitted to arbitration by the Regulatory Authority.
                           Furthermore, the payment condition currently in force
                           is pending approval by the Board of Directors. In the
                           opinion of the Subsidiary Company and its legal
                           counsel, an adverse decision in relation to the
                           aforementioned dispute is considered not probable.

                  Clarifying notes:
                  -----------------

                  (a)      The Subsidiary Company, together with Camuzzi Gas del
                           Sur S.A. has a dispute with Camuzzi Argentina S.A.,
                           as regards the ownership of the invoicing and
                           collection system (AG system) and others. As of the
                           date hereof, the parties are negotiating in order to
                           resolve the dispute. The parties have agreed that if
                           they cannot solve the dispute, the same shall be
                           submitted to arbitration by an independent expert.

                  (b)      Camuzzi Gas Pampeana S.A. has not recognized higher
                           costs claimed by Camuzzi Argentina S.A. in relation
                           to the work inspection services for the gas pipeline
                           of the coast for Ps. 840,809. The Subsidiary Company
                           understands that such costs are not applicable since
                           they are not considered in the respective agreement.
                           As of the date hereof, the Companies are negotiating
                           in order to resolve the dispute. In the opinion of
                           the Subsidiary Company and its legal counsel, an
                           adverse decision in relation to the aforementioned
                           dispute is considered not probable.



NOTE 6:           MANDATORY INVESTMENTS OF THE SUBSIDIARY COMPANY

                  Subsidiary Company, Camuzzi Gas Pampeana S.A., must undertake
                  a five-year plan from 1993 to 1997, which includes investments

                  corrosion, communications equipment and SCADA (centralized
                  telemeasurement and control equipment system).

                  The amounts of the investments, as set by the License for each
                  year, are the following:

                  Furthermore, 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.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  Subsidiary Company received a payment in cash of Ps. 133,570,
                  while for the remaining Ps. 517,455 a fixed-term deposit
                  maturing on May 14, 2001 was made.

                  For the balance of preferred liabilities for deposits not
                  assumed by Mercobank S.A., Camuzzi Gas Pampeana S.A. received
                  Ps. 861,401 in Series C Certificates of the trust created by
                  Mercobank S.A., of which Promotora Fiduciaria S.A. is a
                  trustee; such amount equals to 40% of the aggregate amount due
                  from Banco Credito Provincial S.A.

                  On August 25, 1998, Mercobank S.A. capitalized 22.53% of the
                  values expressed as Series C Certificates in shares.

                  In that sense, 194,076 ordinary shares, NV Ps. 1 (Peso One)
                  each, have been subscribed. Consequently, as of December 31,
                  1998, the amount of the shares and Series C Certificates total
                  Ps. 840,126 and Ps 667,325, respectively.

                  The Subsidiary Company set up an allowance of Ps. 516,000,
                  which represents the portion of uncertain recovery of the
                  value of the Series C Certificates received by Camuzzi Gas
                  Pampeana S.A. Regarding the shares held by the Subsidiary
                  Company, as mentioned in Note 2.f., the same were valued at
                  their estimated recovery value, and, consequently, an
                  allowance for depreciation amounting to Ps. 291,434 has been
                  set up.

                  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.

                  Furthermore, on February 3, 1997, by means of Resolution No.
                  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 resulted 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 Resolution No. 587, dated March
                  16, 1998, whereby it established the consideration to be
                  granted to the clients, in accordance with the methodological
                  guidelines included therein.

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

                  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 Subsidiary Company on the grounds that it affects its
                  legitimate rights. However, the Subsidiary Company made an
                  analysis to determine the amount to be discounted in
                  compliance with such order. As a result of such work, it was
                  established that in the event that the existing users and the
                  potential users to be included in the assets transferred
                  without monetary compensation to the Subsidiary Company are
                  entitled to the discounts set forth in the ENARGAS'
                  resolutions, the increase in the liabilities would amount to a
                  maximum of Ps. 1.7 million. In addition, it should be noted
                  that such liability may be substantially lesser due to the
                  fact that as of the date of the financial statements the
                  number of users entitled to such discount cannot be
                  determined, and so the liability shall be acknowledged to the
                  extent that the amount to be paid to users is agreed.

                  Considering that the Subsidiary Company accountably keeps a
                  voluntary reserve which includes the undertakings financed by
                  third parties users and transferred free of charge, the
                  above-mentioned adjustment, if any, shall be accounted as a
                  withdrawal of said reserve, in which case the final balance of
                  the same would amount approximately to Ps. 42.8 million.

                  As regards the networks transferred without monetary
                  compensation, the liability shall also be acknowledged to the
                  extent that the amount to be paid to users.

NOTE 12:          LEGAL AND TAX MATTERS OF THE SUBSIDIARY COMPANY

                  a.       Income tax
                           ----------

                  On January 30, 1998 and May 28, 1998, the Subsidiary Company
                  amended its tax returns by changing the depreciation of the
                  fixed assets received free of charge, as a consequence of the
                  new tax determination corresponding to the amounts of the
                  networks added by the Licensee up to June 1995, by application
                  of the ENARGAS' Resolutions governing the transfer of networks
                  funded, in whole or in part, by third parties; and fully paid
                  the difference originated in the deduction of the tax on
                  assets.

                  On June 22, 1998, the Argentine Tax Authority ("AFIP") gave
                  notice of the adjustments proposed by the inspections which
                  amount to Ps. 2,609,982 for the deduction of the tax on assets
                  applicable in 1993 and 1994, and to Ps. 22,654,073
                  corresponding to computation differences originated in the
                  treatment as non-assessable income granted by Camuzzi Gas
                  Pampeana to the networks received free of charge, which was
                  answered by the Company on July 14, 1998.

                  Furthermore, on August 23, 1998, a copy of the amended tax
                  returns requested by the Division Determinacion de Oficio of
                  the AFIP was attached to the answer.

                  Said amendments were not considered by the AFIP at the time of
                  serving the notice.

                  On January 15, 1999, an order from the Division Determinacion
                  de Oficio (Official Assessment Division) was received,
                  requesting the Division Fiscalizadora Externa II (External
                  Control Division II) to attach within a 30-business day term,
                  a technical report as regards the different aspects included
                  in the Subsidiary Company's answer. As of the date hereof, the
                  Company is preparing the answer to the requirement made by the
                  Division Fiscalizadora Externa II.

                  In the opinion of the Subsidiary Company and its legal
                  counsel, the filing of the amended tax returns applying the
                  criteria of the ENARGAS for tax purposes, and the inclusion of
                  the adjusted amounts in the Installment Payment System
                  (Regimen de Facilidades de Pago) would settle the matter,
                  since interests of the tax authority would be satisfied, and
                  therefore any attempt by it to re-open the case would not be
                  successful.

                  b.       Gross sales tax - Province of Buenos Aires
                           ------------------------------------------

<PAGE>   21

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


                  The Province of Buenos Aires Revenue Board (the "DPRPBA") made
                  assessments questioning the Subsidiary Company's Gross Sales
                  Tax returns, and claiming Ps. 8,853,585 and Ps. 7,386,021 for
                  the periods from December 1992 through February 1995, and from
                  March 1995 to June 1996, respectively, not including fines and
                  accessory charges. Such 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.

                  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.

                  Even though the Subsidiary Company's legal counsel considered
                  that the Subsidiary Company's defense was based on solid
                  grounds, the Final Opinion issued by the General Revenue Board
                  significantly changes 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 Subsidiary 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, and because its property would be subject to
                  attachment during the course of such proceeding, on December
                  19, 1996, the Subsidiary Company availed itself of the Debt
                  Consolidation Regulations pursuant to the provisions of the
                  provincial law 11,808. (Official Gazette July 10, 1996).

                  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 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.

                  Through Resolution No. 544 dated November 17, 1997 and
                  pursuant to the regulatory framework of the activity, the
                  ENARGAS 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.

                  Therefore, and as mentioned before, because a "change of tax
                  rules" generates a right for the Subsidiary 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.

                  At December 31, 1998, the receivable to be recovered (which
                  includes accrued interest) amounts to Ps. 29,912,729, of
                  which, Ps. 4,509,822 were recorded under "Other Current
                  Accounts Receivable" and Ps. 25,402,907 under "Other
                  Non-Current Accounts Receivable".

                  c.       Municipal taxes on use of easements
                           -----------------------------------

                  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 Company 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

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                  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.

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

                  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 Ps. 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 Ps. 69,078, without interest and
                  penalties.

                  The Lower Court sustained the complaint and rejected the
                  defenses filed by the Company. Camuzzi Gas Pampeana S.A.
                  appealed to the Court of Appeals, which upheld the decision. A
                  Provincial Extraordinary Motion was filed.

                  The Supreme Court of the Province rejected our Provincial
                  extraordinary motion. An extraordinary motion was filed with
                  the Federal courts against such decision. The Supreme Court of
                  the Province rejected the Extraordinary Remedy filed by the
                  Subsidiary Company and this Company further submitted a Claim
                  for Reconsideration to the Supreme Court of the Argentine
                  Republic, which was rejected.

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

                  In addition, the Municipality has filed a new claim for an
                  amount of Ps. 506,225.77 for the periods from January 1993 to
                  December 1994 and July 1995 to December 1995, inclusive,
                  therefore the Subsidiary Company filed a response and set up
                  an allowance of Ps. 380,000, included under the item
                  "Provisions". Subsequently, the Municipality reduced the
                  amount of its claim to Ps. 372,674, which was paid under
                  formal protest and with the right to exercise the
                  corresponding judicial actions. Furthermore, it was agreed
                  that the Municipality shall invest the aggregate amount paid
                  in gas networks for the city and said works are currently
                  being carried out.

                  Together with our external counsels, we have been evaluating
                  the possibility of instituting an independent action seeking
                  the declaration of unconstitutionality of the rules taxing the
                  occupancy of public places in relation to gas installations,
                  and a request for an injunctive relief until the matter is
                  settled.

                  Municipality of Saladillo, Province of Buenos Aires: The
                  principal amount claimed totals Ps. 55,542.

                  The claim was submitted and is pending consideration by the
                  administrative court with an answer filed by Camuzzi Gas
                  Pampeana S.A. The municipality has notified the Subsidiary
                  Company that the claim for the collection of such tax has been
                  dismissed.

                  Municipality of Realico, Province of La Pampa: The principal
                  amount claimed totals Ps. 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 Ps. 6,300. The Subsidiary
                  Company has filed a remedy for reconsideration.

                  Municipality of Las Flores, Province of Buenos Aires: The
                  principal amount claimed totals Ps. 20,083 and Ps. 10,000 as
                  interest and court fees. Upon the executive demand, the
                  Subsidiary Company answered by filing objections to the
                  action.

                  The Subsidiary Company has set up an allowance of Ps. 15,000,
                  which is included under the item "Provisions".

                  In the opinion of the Subsidiary Company, and except for the
                  lawsuit with the Municipality of Santa Rosa and Las Flores,
                  for which provisions have been set up, an adverse decision in
                  relation to the aforementioned claims is considered not
                  probable.

                           ---------

                  d.1.     The Revenue Board of the Province of Neuquen notified
                           Camuzzi Gas del Sur S.A. in relation to the contracts
                           for the purchase of gas entered into jointly with the
                           Subsidiary Company, an amended amount of Ps.

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

                           10,400,134 involving the liquidation performed by the
                           supervisors. Subsequently, the notice was answered
                           and the resolution was interrupted on account of the
                           moratorium decrees. Subsequently, notes were filed
                           with the Argentine Ministry of Economy requesting an
                           opinion from the Minister in connection therewith.
                           The province issued Special Decree No. 3534 for the
                           regulated companies to avail themselves of the
                           moratorium, the limit to do so expired on November 6,
                           1998, and was renewed until January 11, 1999.

                           As of December 31, 1998, the Subsidiary Company
                           recorded an allowance of Ps. 1,536,551 in this
                           respect.

                           On January 7, 1999, the ENARGAS submitted a report to
                           the Argentine Ministry of Economy, expressing that
                           "the taxes claimed by Neuquen, will unfailingly lead
                           to a tariff increase with a serious damage for the
                           users".

                           The expiration of the time limit occurred on January
                           11, 1999 has not been renewed. The Licensee Company
                           is waiting for an opinion from the Ministry of
                           Economy as regards this issue.

                  d.2      The Province of Neuquen's Revenue Board has served a
                           notice to the Subsidiary Company claiming a principal
                           amount of approximately Ps. 6.2 million. This amount
                           corresponds to the stamp tax derived from the
                           transport agreements entered into with Transportadora
                           de Gas del Sur S.A., before take-over, when Gas del
                           Estado S.E. was the only shareholder of the
                           Subsidiary Company. The Subsidiary Company notified
                           its position to Gas del Estado.

                           The Subsidiary Company believes that these agreements
                           were not subject to provincial stamp tax due to the
                           fact that the parties who entered into said
                           agreements were Argentine state-owned companies, and
                           are therefore exempt from such tax. Although such
                           agreements were subject to stamp tax, the company
                           considers that Gas del Estado S.E. would be the party
                           liable for the payment of this tax, in accordance
                           with the provisions of the Transfer Agreement.

                           In the opinion of the Subsidiary Company and its
                           legal counsels, except for what is mentioned in item
                           d.1., an unfavorable resolution with respect to such
                           claims is considered not probable.

         e.       Others
                  ------

                  On August 8, 1998, the Ministry of Economy and Public Works
                  and Services filed a claim for Ps. 656,485 for differences in
                  the collection of overdue bills; Camuzzi Gas Pampeana was in
                  charge of their collection for the account of Gas del Estado
                  S.E, pursuant to Schedule XXI of the Share Transfer Agreement.

                  The Subsidiary Company duly set up an allowance to meet the
                  claim for Ps. 220,000, which amount is considered sufficient.

NOTE 13:          SUBSIDIARY COMPANY'S ESSENTIAL ASSETS INVENTORY

                  In compliance with ENARGAS' Resolution No. 60, the Subsidiary
                  Company made an inventory of the assets essential for the
                  service as of December 31, 1997, which was certified on
                  October 26, 1998 by an independent expert specialized in that
                  field.

                  As a result of said work, differences were detected between
                  the accounting inventory and the physical one, which reduce
                  the assets timely recorded in an amount of approximately Ps.
                  12.8 million.

                  Due to the fact that the Subsidiary Company maintains a
                  voluntary reserve account consisting of earnings derived from
                  financial undertakings by third parties users and transferred
                  free of charge, the Company adjusted the aforementioned
                  differences against the voluntary reserve.

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 sub-area 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.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


                  During the year 1997, 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 1997 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:          SUBSIDIARY COMPANY'S SALES OF LIQUIDS

                  As required by ENARGAS through its note No. 3299 dated October
                  26, 1994, the Subsidiary Company's sales of extracted liquids
                  and their respective costs for the fiscal year ended December
                  31, 1998 are disclosed below:


                                                                 (Pesos)

                       Direct costs of sales                     13,472,821



NOTE 16:          INFORMATION SYSTEMS ADAPTATION PROCESS (UNAUDITED)

                  The Subsidiary Company began a process to update its
                  information systems and related technologies, which has been
                  given priority by the Board of Directors. The methodology of
                  work adopted allocates to different engagement teams the
                  finding of a solution for the administrative, invoicing, human
                  resources, hardware and software systems.

                           S.A. for the rendering of public utility services has
                           been determined considering the purchase price paid

                           AND ITS SUBSIDIARY COMPANY
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 20:          RESTRICTION ON FUNDS

                  The Argentine Central Bank (the "BCRA") resolved, under
                  Resolution No. 365 dated August 20, 1997, the complete
                  suspension of the transactions of Banco Credito Provincial
                  S.A., except for those transactions related to the Central
                  Bank derived from monetary regulation and/or exchange
                  transactions; transactions related to purchase and credit
                  cards existing at that 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 pension and survivors'
                  benefits with funds provided by the National Administration of
                  Social Security.

                  In addition, on December 18, 1997, the BCRA through Resolution
                  No. 741 authorized the group of mayor depositors of Banco
                  Credito Provincial S.A., to integrate a retail commercial bank
                  named Mercobank S.A., created pursuant to the provisions of
                  section 7 of the Financial Institutions Law. Furthermore,
                  B.C.R.A. Resolution No. 742 resolved that the privileged
                  assets and liabilities of the Banco Credito Provincial S.A.
                  should be excluded.

                  Furthermore, the exclusion of privileged liabilities was
                  effected for a maximum total amount equivalent to the assets
                  excluded, and the transfer of these assets and liabilities to
                  Mercobank S.A. was authorized, as well as the subscription of
                  the capital stock by the major depositors for an amount of up
                  to Pesos 28,000,000.

                  Mercobank S.A. acknowledged EDEA S.A. deposits for Pesos
                  1,435,528 equivalent to 60% of the total amount owed by Banco
                  Credito Provincial, and EDEA, as major depositor, instructed
                  the institution about the application of these deposits for an
                  amount of up to Pesos 717,764 earmarked for the subscription
                  of 717,764 ordinary shares, with a face value of Pesos 1 each,
                  as irrevocable capital contribution.

                  In exchange for the difference in this connection, on May 19,
                  1998 the company received from Mercobank S.A. a certificate
                  covering a time deposit and on June 3, 1998 it collected the
                  coupon No. 1 plus interest accrued for Pesos 147,560. The
                  remaining coupon of Pesos 574,351 will mature on May 14, 2001
                  and the monthly collection of interest thereon was arranged.

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 20:          (Continued)

                  In exchange for the balance of privileged liabilities for
                  deposits not assumed by Mercobank S.A., EDEA S.A. would
                  receive Pesos 957,017 in Class C Participation Certificates of
                  the trust set up by Mercobank S.A., of which Promotora
                  Fiduciaria S.A. is the trustee; those certificates are
                  equivalent to 40% of the total amount owed by Banco Credito
                  Provincial S.A.

                  On August 25, 1998, Mercobank S.A. subscribed 215,620 ordinary
                  shares, with a face value of Pesos 1 each, through the
                  capitalization of Pesos 215,620 of the amount of the Class C
                  Participation Certificates of the trust mentioned in the
                  preceding paragraph. In view of this, the balance of those
                  certificates totals Pesos 741,397. The controlled company
                  decided to set up an allowance of Pesos 593,118, which
                  represents the portion of doubtful recovery of the value of
                  the class C certificates received by the Company.

                  At December 31, 1998, the Extraordinary net income/(loss)
                  caption includes the increase of Pesos 236,485 in the
                  aforementioned allowance during this year, net of differences
                  acknowledged by Mercobank S.A. for the deposits in checking
                  account and savings account timely effected by Banco Credito
                  Provincial S.A. and the allowance of Pesos 323,808 for the
                  valuation of Mercobank S.A.'s treasury stock at the estimated
                  recoverable value.

NOTE 22:          RECOVERY OF BAD DEBT ALLOWANCE, AGOSBA AND MUNICIPALITY OF

                  During this year, and based on the negotiation conducted by
                  EDEA S.A., the debt agreements involving AGOSBA and the
                  Municipality of General Alvarado transferred by ESEBA have
                  been refinanced. This refinancing led to a recovery of the bad
                  debt allowance estimated at the takeover date. This recovery
                  amounts to Pesos 551,000 and Pesos 2,300,000, respectively,
                  under the guarantees received and the concrete possibilities
