                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)



NOTE 1 BASIS OF FINANCIAL STATEMENTS

  The accompanying consolidated financial statements of United Meridian
Corporation (UMC or the Company) included herein have been prepared, without
audit, pursuant to the rules and regulations of the Securities and Exchange
Commission (SEC).  Although certain information normally included in financial
statements prepared in accordance with generally accepted accounting principles
has been condensed or omitted, UMC believes that the disclosures are adequate to
make the information presented not misleading.  The financial statements should
be read in conjunction with the consolidated financial statements and notes
thereto for the year ended December 31, 1996.

  The financial statements reflect all normal recurring adjustments that, in the
opinion of management, are necessary for a fair presentation.

NOTE 2 ACQUISITIONS AND DISPOSITIONS

  As part of its on-going operations, the Company continually sells producing
and undeveloped reserves and related assets. Certain transactions occurring in
the periods presented are discussed below.

  During the three months ended March 31, 1997, the Company sold various non-
strategic North American properties for total proceeds of $3,314,000 resulting
in pre-tax gains of $827,000.

  In late 1995, the Company agreed to assign to Yukong Limited a portion of its
interests in Blocks CI-01 and CI-02 in Cote d'Ivoire and Blocks B, C and D in
Equatorial Guinea.  Mobil Equatorial Guinea, Inc. (Mobil) subsequently exercised
its preferential right to purchase the interest in Block B in lieu of the
proposed assignment to Yukong Limited.  Under the agreements, the Company
received $5,441,000 in cash in the first quarter of 1996 resulting in a pre-tax
gain of $4,764,000.

  During the first quarter of 1996, the Company sold various other non-strategic
North American properties for total proceeds of $2,079,000, resulting in pre-tax
gains of $761,000.

NOTE 3 FINANCIAL INSTRUMENTS

  The Company has, from time to time, entered into hedging transactions to
reduce its exposure to both crude oil and natural gas price reductions and
increases in interest rates.

  The Company hedged a portion of its oil production with collar agreements in
the first three months of 1997, resulting in a $364,000 downward adjustment to
oil revenues.  Details of contracts in place at March 31, 1997 are described
below.

  At March 31, 1997, the Company had oil collar contracts on 200,000 barrels of
oil per month for April 1997 through June 1997 with a "floor" price of $21.00
and an average "cap" price of $24.69.  UMC's current hedging agreements are
settled on a monthly basis.  All of UMC's current contracts specify the third-
party index to be the New York Mercantile Exchange (NYMEX) futures contract
prices for the applicable commodity, matching the appropriate basis risk.  There
was no deferred hedge gain or loss for crude oil at March 31, 1997.

  Effective January 18, 1994, UMC entered into five-year fixed LIBOR interest
rate swap contracts that provide for fixed interest rates to be realized on
notional amounts of $30,000,000 in 1994 and $45,000,000 from 1995 through 1998.
The agreement includes varying annual fixed interest rates ranging from 3.66% in
1994 to 6.40% in 1998, plus interest rate margins.  Due to the November 1996
pay-down of  amounts outstanding under the Credit Facility, the Company did not
have notional amounts of floating rate debt totaling $45,000,00 and therefore
could no longer apply hedge accounting.  As such, 

                                      -6-
<PAGE>
 
a gain of $486,000 was recorded as other income during the first quarter of
1997.

NOTE 4 BANK FACILITY

  During March 1997, the Company completed negotiations to expand the Credit
Facility to $300,000,000 with an initial borrowing base of $275,000,000.  The
new facility was expanded to include the Company's international assets.  At
March 31, 1997, there were no outstanding borrowings.

NOTE 5 IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARD

  The Financial Accounting Standards Board (FASB) recently issued Statement of
Financial Accounting Standard (SFAS) No. 128, "Earnings per Share" superseding
Accounting Principles Board (APB) No. 15.  The main goals of the FASB were to
harmonize the earnings per share calculation in the United States with those
common in other countries and with International Standard No. 33 and to address
criticism that APB No. 15 contained unnecessarily complex and arbitrary
provisions.  Although SFAS No. 128 cannot be adopted until December 15, 1997,
pro forma disclosures are allowed to minimize the impact of year-end adoption.
Therefore, the following pro forma information is presented:
 
                                            For the three months ended March 31,

     Diluted EPS, as restated                  $ .17                    $ .10
                                            ============            ============

  As mandated by SFAS No. 128, basic earnings per common share is computed by
dividing net income by the weighted average number of shares of common stock
outstanding during the year.  Diluted earnings per common share is determined
on the assumption that outstanding stock options have been converted using the
average price for the quarter.

NOTE 6 SUPPLEMENTAL GUARANTOR INFORMATION

  In connection with the sale by UMC of the 10-3/8% Senior Subordinated Notes
(Notes) in October 1995, UMC Petroleum Corporation (Petroleum), wholly-owned and
the Company's only direct subsidiary, has unconditionally guaranteed the full
and prompt performance of the Company's obligations under the Notes and related
indenture, including the payment of principal, premium (if any) and interest.
Other than intercompany arrangements and transactions, the consolidated
financial statements of Petroleum are equivalent in all material respects to
those of the Company and therefore the separate consolidated financial
statements of Petroleum are not material to investors and have not been included
herein.  However, in an effort to provide meaningful financial data relating to
the guarantor (i.e., Petroleum on an unconsolidated basis) of the Notes, the
following condensed consolidating financial information has been provided
following the policies set forth below:

     (1)  Investments in subsidiaries are accounted for by the Company on the
          cost basis. Earnings of subsidiaries are therefore not reflected in
          the related investment accounts.

     (2)  Certain reclassifications were made to conform all of the financial
          information to the financial presentation on a consolidated basis. The
          principal eliminating entries eliminate investments in subsidiaries
          and intercompany balances.

THREE MONTHS ENDED MARCH 31, 1997 COMPARED WITH THE THREE MONTHS ENDED 
MARCH 31, 1996.

  Oil and gas revenues for the three months ended March 31, 1997 were $63.5
million, or 36.9% greater than oil and gas revenues of $46.4 million for the
three months ended March 31, 1996.  The increase in oil and gas revenues is
primarily due to increased oil production volumes in West Africa and
improvements in oil and natural gas prices.  The average sales price after
hedging for natural gas increased to $2.47 per Mcf, or 15.4%, in the first
quarter of 1997 as compared to the same period of 1996.  The impact of hedging
on natural gas prices received and natural gas revenues for 1996 was a decrease
of $0.11 per MCF and $1.5 million, respectively.  Natural gas production for the
three months ended March 31, 1997 was 13,175 MMCF, a decrease of 5.9% as
compared to the first quarter of 1996 volumes due primarily to reduced
production from the Gulf of Mexico.  Oil production increased 83.4%, or 754 MBO,
in the first three months of 1997 as compared to the same period in 1996 due
primarily to increased oil production in Cote d'Ivoire and commencement of
production in Equatorial Guinea in August 1996.  The average sales price after
hedging for oil increased to $18.62, or 2.6%, in the three months ended 
March 31, 1997 as compared to the prior year period. The impact of hedging on
oil prices received and oil revenues for the first quarter of 1997 was a
decrease of $0.22 per barrel and $0.4 million, respectively.

  During the three months ended March 31, 1997, the Company sold various non-
strategic North American properties for total cash proceeds of $3.3 million,
resulting in pre-tax gains of $0.8 million.  The first quarter of 1996 gains on
sales of assets resulted primarily from a pre-tax gain of $4.8 million on cash
proceeds of $5.4 million related to the purchase by Mobil of a 10% interest in
Equatorial Guinea Block B.  In addition, the Company sold various non-strategic
North American properties for total cash proceeds of $2.1 million, resulting in
$0.7 million of pre-tax gains.

  Production costs, including ad valorem and production taxes, increased to
$13.2 million, or 3.1%, in the first three months of 1997 as compared to $12.8
million in the comparable period of 1996, primarily due to commencement of
production in Equatorial Guinea in August 1996.  However, on a cost per barrel
of oil equivalent (BOE) basis, production costs in the first quarter of 1997
decreased $0.55 per BOE (13.9%) when compared to the first quarter of 1996.

  General and administrative expenses for the three months ended March 31, 1997
were $2.5 million compared to $3.4 million in the three months ended 
March 31, 1996.  This decrease was primarily due to certain non-cash benefits
accrual reductions in the first quarter of 1997. General and administrative
expenses per BOE of production decreased from $1.05 per BOE in the first quarter
of 1996 to $0.66 per BOE in the comparable period of 1997.

  Exploration, dry hole and lease impairment expenses for the first quarter of
1997 totaled $12.7 million as compared to $4.5 million in the first quarter of
1996.  This increase of $8.2 million was primarily due to increased dry hole
costs experienced in Equatorial Guinea Block D and Cote d'Ivoire Block CI-12.
In addition, the Company had increased geological and geophysical costs in the
1997 period as compared to the 1996 period reflecting a higher level of
exploration activity in Cote d'Ivoire, Equatorial Guinea and North America.

  Depreciation, depletion and amortization (DD&A) expense for the three months
ended March 31, 1997 of $21.1 million increased 6.6% from $19.8 million for the
comparable 1996 period.  This increase is primarily attributable to increased
production levels in Cote d'Ivoire and Equatorial Guinea.  The rate per BOE of
oil and gas DD&A decreased 9.8% from $6.00 per BOE in the first quarter of 1996
to $5.41 per BOE in the 1997 comparable period.  This decrease is primarily due
to a change in the Company's production mix (lower Gulf of Mexico production
with historically high DD&A rates, offset by increased West African production
with lower DD&A rates).

  Interest and debt expense for the three months ended March 31, 1997 was $4.7
million, including non-cash amortization of debt issue costs totaling $0.3
million, compared to $5.5 million in the three months ended March 31, 1996.  The
decrease in interest expense is primarily due to the reduced debt levels in 1997
as a result of debt payments in late 1996 with the proceeds of the November 1996
equity offering.

  An income tax provision of $5.5 million (of which $1.3 million is a current
provision and $4.2 million is a deferred provision) was recognized for the three
months ended 1997, compared to a provision of $2.6 million (of which $0.1
million was a current provision and $2.5 million was a deferred provision) for
the comparable 1996 period.  Significantly impacting first quarter 1997 current
taxes is a $1.2 million non-cash provision representing current taxes incurred
in Cote d'Ivoire which, under the terms of the production sharing contract, will
be paid by the Ivorian government from their production proceeds.  Consistent
with Statement of Financial Accounting Standards (SFAS) 109, Accounting for
Income Taxes, the deferred income tax provision or benefit was derived primarily
from changes in deferred income tax assets and 

                                      -12-
<PAGE>
 
liabilities recorded on the balance sheet.

  The Company reported net income of $6.2 million, or $0.17 per share, for the
first quarter of 1997 compared to a net income of $3.7 million, or $0.10 per
share, for the first quarter of 1996.

CAPITAL RESOURCES AND LIQUIDITY

  The Company has historically funded its operations, acquisitions, exploration
and development expenditures from cash flows from operating activities, bank
borrowings, sales of common and preferred stock, issuance of senior subordinated
notes, sales of non-strategic oil and natural gas properties, sales of partial
interests in exploration concessions and project finance borrowings.

  The primary sources of cash for the Company during the three months ended
March 31, 1997, included proceeds from funds generated from operations, proceeds
from asset sales and exercise of stock options.  In the comparable period of
1996, the primary sources of cash included funds generated from operations,
proceeds from asset sales and bank borrowings.  Primary cash uses for the
quarters ended March 31, 1997 and 1996 included capital expenditures (including
exploration expenses) which totaled $49.0 million and $29.4 million,
respectively.  In addition, during the three months ended March 31, 1997, cash
uses include $2.2 million of debt issue costs as a result of the new Credit
Facility discussed below.

  Discretionary cash flow, a measure of performance for exploration and
production companies, is derived by adjusting net income to eliminate the
effects of exploration expenses, including dry hole costs and impairments, DD&A,
deferred income tax, gain (loss) on sale of assets and non-cash amortization of
debt issue costs.  The effects of working capital changes are not taken into
account.  This measure reflects an amount that is available for capital
expenditures, debt repayment or dividend payments.  The company generated
discretionary cash flow for the three months ended March 31, 1997 and 1996 of
approximately $43.8 million and $25.3 million, respectively.  The 73% increase
in discretionary cash flow in the 1997 period as compared to the 1996 period is
primarily due to increased oil production in Cote d'Ivoire and Equatorial Guinea
and the overall improvements in oil and natural gas prices.

  The company has used the Credit Facility to partially finance its
expenditures.  During March 1997, the Company completed negotiations to expand
the Credit Facility to $300 million from $200 million with an initial borrowing
base of $275 million.  As of March 31, 1997, the Company had no outstanding
loans thereunder and outstanding letters of credit of approximately $0.6
million.  Resulting liquidity (including cash) at March 31, 1997 was
approximately $338 million.  As of December 31, 1996, the borrowing base under
the Credit Facility was $200 million, and the Company had no outstanding loans
thereunder and outstanding letters of credit of approximately $0.6 million.
Resulting liquidity (including cash) exceeded $254 million.

  As part of its on-going operations, the Company periodically sells interests
in proved reserves and enhanced exploration prospects.  This practice continued
in the first quarters of 1997 and 1996, with net cash proceeds from sales of
assets of $3.3 million and $7.5 million, respectively.  During the three months
ended March 31, 1997, the cash proceeds were generated through the sale of
various non-strategic North American properties.  These proceeds were used to
redeploy capital to domestic and international opportunities which management
believes represent higher rates of return.

  The Company's capital expenditure budget for 1997 is expected to be
approximately $250 million, consisting of approximately $84 million for
exploration, approximately $159 million for development and approximately $7
million of other capital expenditures.  Primary areas of emphasis will be East
Texas, the Gulf of Mexico and Western Africa.  Based upon the results of
exploration activities during 1997, the operating capital budget could be
expanded by approximately $50 million for follow-up appraisal or development
expenditures.  Funding for capital expenditures is anticipated to come from
present cash on hand, discretionary cash flow and, if necessary, borrowings
under the credit facility.  In addition, the Company will evaluate its level of
capital spending throughout the year based upon drilling results, commodity
prices, cash flows from operations and property acquisitions.  Actual capital
spending may vary from the initial capital expenditure budget.

  Due to the aforementioned expanded credit facility and the equity offering
completed in November 1996, the Company's financial structure has been
significantly strengthened.  The Company's debt to total capitalization ratio
has decreased to 26.2% at March 31, 1997, from 26.7% at December 31, 1996.
Combined with cash flows from operating activities, the Company has the
financial strength, leverage and liquidity that will allow it to fund the 1997
capital 

                                      -13-
<PAGE>
 
expenditure program, including the international exploration and development
opportunities in Cote d'Ivoire and Equatorial Guinea, and continue to
selectively pursue strategic corporate and property acquisitions.

  The Company's interest coverage ratio (calculated as the ratio of income from
operations plus DD&A and exploration expense to interest plus capitalized
interest less non-cash amortization of debt issue costs) was 11.3 to 1 for the
first quarter of 1997, compared with 6.4 to 1 for the first quarter of 1996.

FOREIGN CURRENCY TRANSACTIONS

  The Company conducts a portion of its business in Canadian dollars.
Therefore, a portion of the Company's business is subject to fluctuations in
currency exchange rates.  In preparing the Company's financial statements, the
results of operations of the Canadian subsidiary are generally translated at the
average exchange rate for the year-to-date, and the subsidiary's assets and
liabilities are translated at the rate of exchange in effect on the balance
sheet date.

  The majority of revenues and expenditures for the Company's West African
operations are settled and all books and records are maintained in the U.S.
dollar.

CHANGES IN PRICES AND INFLATION

  The Company's revenues and the value of its oil and natural gas properties
have been, and will continue to be, effected by changes in oil and natural gas
prices.  The Company's ability to maintain its current borrowing capacity and to
obtain additional capital on attractive terms is also substantially dependent on
oil and natural gas prices.  Oil and natural gas prices are subject to
significant seasonal, market and other fluctuations that are beyond the
Company's ability to control or predict.  Although certain Company costs and
expenses are effected by the level of inflation, inflation did not have a
significant effect on the Company's results of operations for the first three
months of 1997 or 1996.
