                   HARKEN ENERGY CORPORATION AND SUBSIDIARIES
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                             JUNE 30, 1997 AND 1998
                                   (Unaudited)

(1)  MANAGEMENT'S REPRESENTATIONS

     In the opinion of Harken Energy Corporation ("Harken"), the accompanying
unaudited consolidated condensed financial statements contain all adjustments
necessary to present fairly its financial position as of December 31, 1997 and
June 30, 1998 and the results of its operations and changes in its cash flows
for all periods presented as of June 30, 1997 and 1998. These adjustments
represent normal recurring items.

     The accompanying unaudited condensed financial statements have been
prepared pursuant to the rules and regulations of the Securities and Exchange
Commission ("SEC"). Certain information and note disclosures normally included
in annual financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to these rules and
regulations, although Harken believes that the disclosures made are adequate to
make the information presented not misleading. It is suggested that these
condensed financial statements be read in conjunction with the financial
statements and the notes thereto included in Harken's Form 10-K for the year
ended December 31, 1997.

     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 reported
period. Actual results could differ from these estimates.

     The results of operations for the six month period ended June 30, 1998 are
not necessarily indicative of the results to be expected for the full year.

(2)  ACQUISITIONS

     On August 29, 1997, Harken, along with Harken Exploration Company, a
wholly-owned subsidiary, purchased working interests in oil and gas properties
located in the panhandle region of Texas (the "Cal-T Properties"). The purchase
price of approximately $3,416,000 consisted primarily of 565,000 shares of
Harken common stock.

     On May 19, 1998, Harken, along with Harken Exploration Company, a
wholly-owned subsidiary, purchased working interests in oil and gas properties
located in southern Louisiana (the "Bargo Properties") from St. Martinville
Partners, Ltd. and Bargo Energy Company (collectively "the Sellers"). The
purchase price consisted of 2,716,483 shares of Harken common stock, having an
approximate value of $16,250,000, which were issuable at closing. According to
the Asset Purchase and Sale Agreement, additional consideration having a value
of $4,000,000 less certain adjustments, is payable by Harken to the Sellers if
the Sellers are able to obtain new or renewal leases for certain of the Bargo
Properties. Such adjustments may include unresolved title issues on certain
leases and an allowance of up to a maximum of $750,000 for environmental and
regulatory compliance. The additional consideration is to be paid 120 days after
closing and is payable at Harken's option in the form of additional shares of
Harken common stock or cash. See Note 11--Related Party Transactions for a
discussion of the relationship between Harken and the Sellers.

(3)  MARKETABLE SECURITIES

     Included within cash and temporary investments and cash in segregated
accounts at December 31, 1997 and June 30, 1998 are certain investments in
marketable debt securities having maturities of sixty days or less. Harken
management determines the appropriate classification of such debt securities at
the time of purchase and reevaluates such designation as of each balance sheet
date. Such debt securities are classified as held-to-maturity as Harken has the
positive intent and ability to hold the securities to maturity. Held-to-maturity
securities are stated at amortized cost, adjusted for amortization of premiums
and accretion of discounts to maturity. Such amortization is included in
interest and other income. Harken holds no securities which are classified as
available-for-sale or trading.

     The following is a summary of held-to-maturity securities:




                                                               December 31,           June 30,

(5)  COLOMBIAN OPERATIONS

     Harken's Colombian operations are conducted through Harken de Colombia,
Ltd., a wholly-owned subsidiary of Harken, which held six exclusive Colombian
Association Contracts with Empresa Colombiana de Petroleos ("Ecopetrol") as of
June 30, 1998. These Association Contracts include the Alcaravan Contract,
awarded in 1992, the Bocachico Contract, awarded in 1994, the Cambulos Contract,
awarded in 1995, the Bolivar Contract, awarded in 1996, the Miradores Contract,
awarded in December 1997, and the Los Olmos Contract, awarded in March 1998. The
Alcaravan and Miradores Contracts currently cover a combined area of
approximately 242,000 acres in the Llanos Basin of Eastern Colombia. The
Bocachico and Cambulos Contracts cover a combined area of approximately 492,000
acres in the Middle Magdalena Valley of Central Colombia and the Bolivar
Contract covers an area of approximately 250,000 acres in the Northern Middle
Magdalena Valley of Central Colombia. The Los Olmos Contract covers
approximately 374,000 acres in the Lower Magdalena Valley of Northern Colombia.
Terms of each of the Association Contracts commit Harken to perform certain
activities in accordance with a prescribed timetable. As of August 1, 1998,
Harken was in compliance with the requirements of each of the Association
Contracts, as amended.

     Under the terms of the Association Contracts, if, during the first six
years of each contract, Harken discovers one or more fields of producing oil or
gas in quantities that are economically exploitable and Ecopetrol agrees that
such field is economically exploitable (a "commercial discovery"), the term of
that contract will be extended for a period of 22 years from the date of such
commercial discovery. Upon discovery of a field capable of commercial
production, and upon commencement of production from that commercial field,
Ecopetrol will begin to reimburse Harken for 50% of Harken's successful well
costs expended up to the point of declaration of a commercial discovery plus,
in the case of the Cambulos, Bolivar, Miradores and Los Olmos Contracts, 50% of
all seismic and dry well costs incurred prior to the point of declaration of a
commercial discovery. Production from a commercial discovery will be allocated
as follows: Ecopetrol, on behalf of the Colombian government, will receive a
20% royalty interest in all production, and all production (after royalty
payments) will be allocated 50% to Ecopetrol and 50% to Harken until cumulative
production from all fields (or the particular productive field under certain of
the Association Contracts) in the Association Contract acreage reaches 60
million barrels of oil. As cumulative production increases in excess of 60
million barrels of oil, Ecopetrol's share of production will increase
progressively (to a maximum of 75% under certain of the Association Contracts)
with a corresponding decrease in Harken's share of production. After a
declaration of a commercial discovery, Harken and Ecopetrol will be responsible
for all future development costs and operating expenses in direct proportion to
their interest in production. For any fields that are not declared by Ecopetrol
to be a commercial discovery, Harken would retain the rights to all production
after royalty.                

     Harken has entered into certain development finance and operating
agreements with outside parties whereby such parties have received a beneficial
interest in certain of Harken's Colombian operations. For further discussion,
see Note 6 -- Development Finance and Operating Agreements.


(6)  DEVELOPMENT FINANCE AND OPERATING AGREEMENTS

     Rio Negro Development Finance Agreement -- In October 1995, Harken entered
into a Development Finance Agreement (the "Rio Negro Development Finance
Agreement") with Arbco Associates L.P., Offense Group Associates L.P., Kayne
Anderson Nontraditional Investments L.P. and Opportunity Associates L.P.
(collectively, the "Rio Negro Investors"), pursuant to which the Rio Negro
Investors 


                                       10
   11

provided $3,500,000 to Harken to finance drilling on the Rio Negro prospect in
the Bocachico Contract area in exchange for the right to receive future payments
from Harken equal to 40% of the net profits that Harken de Colombia, Ltd. may
derive from the sale of oil and gas produced from the Rio Negro prospect (the
"Rio Negro Participation").

     In March 1997, Harken and the Rio Negro Investors entered into a Conversion
Agreement whereby Harken purchased 75% of the Rio Negro Participation in
exchange for 900,000 restricted shares of Harken common stock. From the
remaining 25% of the Rio Negro Participation retained, the Rio Negro Investors
have the right to receive 10% of the net profits that Harken de Colombia, Ltd.
may derive from the sale of oil and gas produced from the Rio Negro prospect.

     Palo Blanco Development Finance Agreements -- In June 1996, Harken, along
with Harken de Colombia, Ltd., entered into separate Development Finance
Agreements with two investors. Under the terms of the agreements, the two
investors provided an aggregate of $2,500,000 to finance the drilling of a well
on the Palo Blanco prospect in the Alcaravan Association Contract area. In
return for the $2,500,000, the investors were initially granted a beneficial
interest in 40% of the net profits from the Palo Blanco prospect which might
have been received by Harken de Colombia, Ltd. In 1996, the investors exercised
their rights under the agreement to convert one-half of their beneficial
interest into 599,988 shares of restricted Harken common stock. During the first
quarter of 1997, the investors exercised their right to convert the remaining
portion of their beneficial interest into an additional 599,988 shares of
restricted Harken common stock.

     Rochester Agreement -- Harken de Colombia, Ltd. has entered into an
operating agreement (the "Rochester Agreement") with Rochester Energy
Corporation ("Rochester", a Canadian corporation) pursuant to which Rochester
has paid 33 1/3% of the aggregate costs of the Estero #1 well and related
production facilities on the Palo Blanco prospect, 25% of the aggregate costs
related to the Estero #3 well, and 25% of the aggregate costs of the initial
well drilled on the Anteojos prospect, the Canacabare #1, all of which are
located within the Alcaravan Contract area, along with 25% of the aggregate
costs related to the Miradores Association Contract. In exchange, Rochester
acquired a beneficial interest equal to 25% of the interest held by Harken de
Colombia, Ltd. in the Palo Blanco and Anteojos prospect operations.

     Parkcrest Financing Agreement -- Harken de Colombia, Ltd. has entered into
a financing agreement (the "Parkcrest Financing Agreement") with Parkcrest
Explorations, Ltd. ("Parkcrest", a Canadian corporation) pursuant to which
Parkcrest has paid 33 1/3% of the aggregate costs of the Estero #1 well and
related production facilities on the Palo Blanco prospect, 33 1/3% of the
aggregate costs of the initial well to be drilled on the Anteojos prospect, the
Canacabare #1, and 25% of the aggregate costs related to the Estero #3 well, all
of which are located within the Alcaravan Contract area. In addition, Parkcrest
will pay 33 1/3% of the aggregate costs of the initial well to be drilled under
the Miradores Association Contract. Parkcrest is also responsible for their
contracted percentage share of costs related to seismic on the Alcaravan and
Miradores Contract areas. In exchange, Parkcrest, upon its full performance,
will acquire a beneficial interest equal to 25% of the interest held by Harken
de Colombia, Ltd. in these prospects.

     In April 1998, Harken and Parkcrest entered into a Loan and Security
Agreement (the "Parkcrest Loan Agreement") whereby Harken agreed to provide up
to $2,600,000 to Parkcrest to be used as needed by Parkcrest to finance its
share of costs under the Parkcrest Financing Agreement. Under the terms of the
Parkcrest Loan Agreement, any outstanding loans bear interest at 6% per annum in
addition to a monthly management fee payable to Harken of $37,500 per month. Any
outstanding balance pursuant to the Parkcrest Loan Agreement is due and payable
by Parkcrest on November 30, 1998 and is secured by 50% of Parkcrest's
beneficial interest in the Palo Blanco prospect. As of June 30, 1998, Parkcrest
had borrowed 

                                       11
   12

approximately $2,130,000 pursuant to the Parkcrest Loan Agreement, and such
amount is included in accounts and notes receivable in the accompanying balance
sheet.

     EnCap Development Finance Agreement -- In October 1997, Harken entered into
a Development Finance Agreement (the "EnCap Development Finance Agreement") with
EnCap Energy Capital Fund III, L.P., EnCap Energy Capital Fund III-B, L.P., BOCP
Energy Partners, L.P. and Energy Capital Investment Company PLC (collectively
the "EnCap Investors"), pursuant to which the EnCap Investors provided $25
million (the "Payment Amount"), less a 2% investment banking fee, to Harken to
finance the planned drilling of the initial wells on three unexplored oil and
gas prospects in the Middle Magdalena Basin of Colombia. As part of the
transaction, Harken issued 150,000 shares of Harken common stock to the EnCap
Investors. The three well exploratory program contemplates the drilling of one
prospect on Harken's Bocachico Contract area and the drilling of two prospects
on Harken's Cambulos Contract area, including the Islero #1 well which is
scheduled to be spudded in August 1998. In exchange, the EnCap Investors
received the right to receive future payments from Harken equal to 5% of the net
profits that Harken de Colombia, Ltd. may derive from the sale of oil and gas
produced from each of the three prospects if the planned drilling on the
prospect is successful (the "EnCap Participation"). Pursuant to the EnCap
Development Finance Agreement, Harken is obligated to drill each of the three
wells prior to October 2000.

     Pursuant to the EnCap Development Finance Agreement, the EnCap Investors
have the right, for a period of two years beginning in October 1998, to convert
all or part of the EnCap Participation into shares of Harken common stock. The
number of shares of Harken common stock to be issued upon conversion of the
EnCap Participation will be equal to the quotient of (i) the Payment Amount
(less any distributions made in respect of the EnCap Participation) plus an
amount equal to 15% interest per annum on the net Payment Amount compounded
monthly (the "Invested Amount"), divided by (ii) the market price of Harken
common stock at the time of conversion. During the same two year period, Harken
also has the right to convert the EnCap Participation into shares of Harken
common stock with the number of shares of Harken common stock to be issued to be
equal to the quotient of (i) the Payment Amount (less any distribution made in
respect of the EnCap Participation) plus an amount equal to 25% interest per
annum on the net Payment Amount compounded monthly, divided by (ii) the market
price of Harken common stock at the time of conversion. Harken can also elect to
pay cash upon any conversion of the EnCap Participation in lieu of issuing
Harken common stock. The EnCap Development Finance Agreement also provides for
additional shares of Harken common stock to be issued by Harken in the event of
a conversion to the extent that the EnCap Investors do not, under certain
circumstances, realize the Invested Amount from the sale of shares of Harken
common stock issued at the conversion. See Note 11 -- Related Party Transactions
for a discussion of the relationship between Harken and the EnCap Investors.

     European Development Finance Agreements -- In December 1997, Harken entered
into a Development Finance Agreement and other related agreements (the "European
Development Finance Agreement") whereby Sidro S.A., Lambertine Holdings, Ltd.
and Rauscher Pierce and Clark (collectively the "European Investors") purchased
all of the outstanding common stock of Harken Capital Corporation, ("HCC", a
newly-formed U.S. corporation) for $7 million. Pursuant to the European
Development Finance Agreement, HCC then provided the $7 million to Harken in
January 1998 to finance a portion of the cost of the three-well exploratory
program discussed above pursuant to the EnCap Development Finance Agreement. In
exchange, HCC received the right to receive future payments from Harken equal to
1.4% of the net profits that Harken de Colombia, Ltd. may derive from the sale
of oil and gas produced from each of the three prospects if the planned drilling
on the prospect is successful. Beginning in December 1998, the European
Investors have the right to convert their shares of HCC into shares of Harken
common stock with terms substantially identical to the EnCap Development Finance
Agreement. As part of the transaction, Harken 

                                       12
   13

issued 42,000 shares of Harken common stock to the European Investors and paid a
cash fee of $175,000 to one of the European Investors.

     In March 1998, Harken received directly an additional $3 million pursuant
to a Development Finance Agreement with Faisal Finance ("Faisal"), which
contains terms substantially identical to the EnCap Development Finance
Agreement, including conversion provisions which begin in March 1999. In
exchange, Faisal received the right to receive future payments from Harken equal
to 0.6% of the net profits that Harken de Colombia, Ltd. may derive from the
sale of oil and gas produced from each of the three prospects discussed above
pursuant to the EnCap Development Finance Agreement if the planned drilling on
the prospect is successful. As part of this transaction, Harken issued 18,000
shares of Harken common stock and paid a cash fee of $75,000 to a financial
advisor.


(7)  EUROPEAN CONVERTIBLE NOTES PAYABLE

     6 1/2% European Notes -- On July 30, 1996, Harken issued to qualified
purchasers a total of $40 million in 6 1/2% Senior Convertible Notes (the 
"6 1/2% European Notes") which were to mature on July 30, 2000. In connection 
with the sale and issuance of the 6 1/2% European Notes, Harken paid
approximately $3,142,000 from the 6 1/2% European Note proceeds for commissions
and issuance costs. Interest incurred on these notes was payable semi-annually
in January and July of each year to maturity or until the 6 1/2% European Notes
were converted. Such 6 1/2% European Notes were convertible at any time by the
holders into shares of Harken common stock at a conversion price of $2.50 per
share ("the 6 1/2% European Note Conversion Price"). The 6 1/2% European Notes
were also convertible by Harken into shares of Harken common stock after one
year following issuance, if for any period of thirty consecutive days commencing
on or after November 28, 1996, the closing price of Harken common stock for each
trading day during such period shall have equaled or exceeded 135% of the 6 1/2%
European Note Conversion Price (or $3.375 per share of Harken common stock).

     During the last half of 1996, holders of 6 1/2% European Notes totaling
$1,400,000 exercised their conversion option and such holders were issued
560,000 shares of Harken common stock. In February 1997, Harken gave notice as
required under the Trust Indenture that it had met the market price criteria
necessary to call for mandatory conversion of the 6 1/2% European Notes and on
June 2, 1997 formally called the 6 1/2% European Notes for conversion on July
31, 1997. During the first six months of 1997, holders of 6 1/2% European Notes
totaling $19,300,000 exercised their conversion option and such holders were
issued 7,720,000 shares of Harken common stock. On July 31, 1997, Harken
converted the remaining 6 1/2% European Notes into 7,720,000 shares of Harken
common stock.

     5 1/2% European Notes -- On June 11, 1997, Harken issued to qualified
purchasers a total of $70 million in 5 1/2% Senior Convertible Notes ( the 
"5 1/2% European Notes") which were to mature on June 10, 2002. In connection 
with the sale and issuance of the 5 1/2% European Notes, Harken paid
approximately $5,174,000 from the 5 1/2% European Note proceeds for commissions
and issuance costs. Interest incurred on these notes was payable semi-annually
in June and December of each year to maturity or until the 5 1/2% European Notes
are converted. Such 5 1/2% European Notes were convertible into shares of Harken
common stock at an initial conversion price of $5.00 per share, subject to
adjustment in certain circumstances ("the 5 1/2% European Note Conversion
Price"). The Trust Indenture provided for a five percent premium on the number
of shares of Harken common stock issuable on conversion that was paid to holders
converting the 5 1/2% European Notes prior to December 11, 1997. The 5 1/2%
European Notes were also convertible by Harken into shares of Harken common
stock after one year following issuance, if for any period of thirty 

                                       13
   14

consecutive days commencing on or after June 11, 1997, the average of the
closing prices of Harken common stock for each trading day during such thirty
day period shall have equaled or exceeded 130% of the 5 1/2% European Note
Conversion Price (or $6.50 per share of Harken common stock). In October 1997,
Harken met the market price criteria necessary to call for mandatory conversion
of the 5 1/2% European Notes any time on or after June 11, 1998, and provided
notice to the holders as required under the Trust Indenture. In May 1998, Harken
formally called the 5 1/2% European Notes which remain outstanding for
conversion on June 12, 1998. As of December 31, 1997, holders of 5 1/2% European
Notes totaling $30,120,000 exercised their conversion option and such holders
were issued 6,325,200 shares of Harken common stock. During the first six months
of 1998, additional holders of 5 1/2% European Notes totaling $610,000 have
exercised their conversion option and such holders were issued an additional
122,000 shares of Harken common stock. On June 12, 1998, Harken converted the
remaining 5 1/2% European Notes into 7,854,000 shares of Harken common stock.

     Upon closing, all proceeds from the sale of the 6 1/2% European Notes and 
5 1/2% European Notes issuances were each initially paid to a Trustee under the
terms of a Trust Indenture covering each issue and held in separate interest
bearing Trust accounts (the "Segregated Accounts") to be maintained for Harken's
benefit, until the Trustee is presented with evidence of sufficient asset value,
as defined in the Trust Indenture, held by Harken to permit an advance of a
portion of the proceeds. Until all of the 5 1/2% European Notes were converted,
Harken was to maintain an Asset Value Coverage Ratio as defined in the Trust
Indenture. Upon the June 1998 conversion of the 5 1/2% European Notes which
remained outstanding, Harken transferred the approximately $38.6 million
remaining in the Segregated Accounts to its main operating account.

     All Segregated Account cash related to the 5 1/2% European Notes is
reflected as a current asset at December 31, 1997 as all such cash was available
according to the Trust Indenture. The initial cash proceeds from the issuance of
the 5 1/2% European Notes are not included in the Statement of Cash Flows
because the proceeds are not considered to be cash equivalents due to the
Segregated Account requirement of these notes. Transfers of proceeds from the
Segregated Accounts are included in cash flows from financing activities in the
accompanying consolidated statements of cash flows.

     5% European Notes - On May 26, 1998, Harken issued to qualified purchasers
a total of $85 million in 5% Senior Convertible Notes (the "5% European Notes")
which mature on May 26, 2003. In connection with the sale and issuance of the 5%
European Notes, Harken paid approximately $4,256,000 from the 5% European Notes
proceeds for commissions and issuance costs. Interest incurred on these notes is
payable semi-annually in May and November of each year to maturity or until the
5% European Notes are converted. Such 5% European Notes are convertible into
shares of Harken common stock at an initial conversion price of $6.50 per share,
subject to adjustment in certain circumstances ("the 5% European Note Conversion
Price"). The Trust Indenture provides for a three percent premium on the number
of shares of Harken common stock issuable on conversion to holders of the 5%
European Notes who convert prior to November 25, 1998. The 5% European Notes are
also convertible by Harken into shares of Harken common stock after May 26,
1999, if for any period of thirty consecutive days commencing on or after May
26, 1998, the average of the closing prices of Harken common stock for each
trading day during such thirty-day period shall have equaled or exceeded 125% of
the 5% European Note Conversion Price (or $8.125 per share of Harken common
stock). The 5% European Notes may be redeemed for cash, at Harken's option, at
par, in whole or in part, at any time after May 26, 2002, upon not less than 30
days notice to the holders. In addition, beginning November 26, 2002, Harken may
redeem up to 50% of the 5% European Notes in exchange for shares of Harken
common stock at a defined conversion price based on an average market price 

                                       14
   15

of Harken common stock. Beginning May 26, 2003, Harken may similarly redeem all
remaining 5% European Notes. The 5% European Notes are listed on the Luxembourg
Stock Exchange.

         Commissions and issuance costs associated with the European Notes are
deferred and are included in Other Assets and are amortized to interest expense
over the period until conversion or maturity of the European Notes. As European
Notes are converted to Harken common stock, a pro-rata portion of these deferred
costs are charged to Additional Paid-In Capital.

Agreements with two investors. In 1996, the investors exercised their rights
under the agreement to convert one-half of their beneficial interest into

common stock. See Note 6 -- Development Finance and Operating Agreements.

     Rio Negro Development Finance Agreement -- In March 1997, Harken and the
Rio Negro Investors entered into a Conversion Agreement whereby Harken purchased
75% of the Participation relating to the Rio Negro Development Finance Agreement
for 900,000 restricted shares of Harken common stock. These shares were issued
in April 1997. See Note 6 -- Development Finance and Operating Agreements for
further discussion.

     EnCap Development Finance Agreement -- In October 1997, Harken and the
EnCap Investors entered into a Development Finance Agreement under which the
EnCap Investors funded approximately $25 million to finance the drilling of
three wells in the Middle Magdalena Basin of Colombia. Pursuant to the EnCap
Development Finance Agreement, both Harken and the EnCap Investors have the
right under certain circumstances to convert all or part of the EnCap
Participation into shares of Harken common stock. Harken also issued 150,000
shares of Harken common stock to the EnCap Investors. See Note 6 -- Development
Finance and Operating Agreements for further discussion of the EnCap Development
Finance Agreement and Note 11 -- Related Party Transactions for further
discussion of the EnCap Investors.

     European Development Finance Agreements -- In December 1997, Harken, HCC
and the European Investors entered into a Development Finance Agreement under
which HCC funded $7 million in January 1998 to finance the drilling of three
wells in the Middle Magdalena Basin of Colombia. Pursuant to the European
Development Finance Agreement, both Harken and HCC have the right under certain
circumstances to convert some or all of the shares of HCC common stock into
shares of Harken common stock. In addition, Harken issued 42,000 shares of
Harken common stock to the European Investors. In March 1998, Harken entered
into an additional Development Finance Agreement with Faisal, which also

                                       16
   17

contained terms whereby both Harken and Faisal have the right under certain
circumstances to convert part of the Participation into shares of Harken common
stock. In addition, Harken issued 18,000 shares of Harken common stock to a
financial advisor in connection with the Development Finance Agreement with
Faisal. See Note 6 -- Development Finance and Operating Agreements for further
discussion.

     Series F Preferred Stock -- On April 9, 1998, Harken entered into a
Securities Purchase Agreement with RGC International Investors, LDC ("RGC"),
pursuant to which Harken issued to RGC 15,000 shares of its Series F Convertible
Preferred Stock (the "Series F Preferred") in exchange for $15,000,000. The
Series F Preferred is convertible into shares of Harken common stock at a
conversion price based upon the market price of Harken common stock at the time
of conversion. The number of shares of Harken common stock issuable upon
conversion of the Series F Preferred will also include a premium amount equal to
an increase calculated on the face value of the Series F Preferred at 5% per
annum. The Series F Preferred does not pay dividends.

     During the first six months following the issuance of the Series F
Preferred, RGC can elect to convert the shares of the Series F Preferred into
Harken common stock on any day that the closing sales price of the Harken common
stock on the American Stock Exchange is equal to or greater than 115% of the
"Market Price." The Market Price is equal to the lower of (a) the average of the
closing bid prices of Harken common stock for any five consecutive trading days
during the 22 trading days ending one trading day prior to the conversion date,
or (b) the low closing bid price of Harken common stock over the five trading
days ending one trading day prior to the conversion date.

     During the first nine months following the issuance of the Series F
Preferred, the conversion price will be equal to 103% of the Market Price on the
conversion date. On January 9, 1999, the conversion price will be fixed at 90%
of the average of the closing bid prices of Harken common stock for the previous
22 trading days. Beginning February 9, 1999, the conversion price will be fixed
at 90% of the average of the closing bid prices of Harken common stock for the
previous 22 trading days if it would result in a lower conversion price than
that calculated on January 9, 1999. Any shares of Series F Preferred outstanding
on April 9, 1999, will automatically be converted into shares of Harken common
stock at the then applicable conversion price.

     Harken has the option to redeem for cash any shares of Series F Preferred
presented for conversion if (a) prior to January 9, 1999, the closing price of
Harken common stock on the conversion date is less than $4.80, or (b) on or
after January 9, 1999, the then applicable conversion price is less than $4.80,
for an amount equal to the number of shares of Harken common stock that would
otherwise be issuable upon conversion multiplied by the closing price of Harken
common stock on the conversion date.

     At each election to convert shares of Series F Preferred into Harken common
stock, RGC will have the option to purchase from Harken for cash additional
shares of Harken common stock equal to the number of shares issued on such
conversion (less any shares issued in respect of the premium amount) at a
purchase price equal to the then applicable conversion price.

     Stockholder Rights Plan -- In April 1998, Harken adopted a rights agreement
(the "Rights Agreement") whereby a dividend of one preferred share purchase
right (a "Right") was paid for each outstanding share of Harken common stock.
The Rights will be exercisable only if a person acquires beneficial ownership of
15 percent or more of Harken common stock (an "Acquiring Person"), or commences
a tender offer which would result in beneficial ownership of 15 percent or more
of such stock. When they become exercisable, each Right entitles the registered
holder to purchase from Harken one one-

                                       17
   18

thousandth of one share of Series E Junior Participating Preferred Stock
("Series E Preferred Stock"), at a price of $35.00 per one one-thousandth of a
share of Series E Preferred Stock, subject to adjustment under certain
circumstances.

     Upon the occurrence of certain events specified in the Rights Agreement,
each holder of a Right (other than an Acquiring Person) will have the right to
purchase, at the Right's then current exercise price, shares of Harken common
stock having a value of twice the Right's exercise price. In addition, if, after
a person becomes an Acquiring Person, Harken is involved in a merger or other
business combination transaction with another person in which Harken is not the
surviving corporation, or under certain other circumstances, each Right will
entitle its holder to purchase, at the Right's then current exercise price,
shares of common stock of the other person having a value of twice the Right's
exercise price.

     Unless redeemed by Harken earlier, the Rights will expire on April 6, 2008.
Harken will generally be entitled to redeem the Rights in whole, but not in
part, at $.01 per Right, subject to adjustment. No Rights were exercisable under
the Rights Agreement at June 30, 1998.

     The terms of the Rights generally may be amended by Harken without the
approval of the holders of the Rights prior to the public announcement by Harken
or an Acquiring Person that a person has become an Acquiring Person.


(9)  PER SHARE DATA

     Basic earnings per common share was computed by dividing net income
attributed to common stock by the weighted average number of shares of Harken
common stock outstanding during the year. Diluted earnings per common share was
determined by including the effect of outstanding options and warrants using
the treasury stock method to the extent that the average share price exceeds
the exercise price. The impact of certain unconverted European Convertible
Notes was not included for the periods ended June 30, 1997 or 1998 as their
effect would have been antidilutive. The impact of unconverted Series F
Preferred Stock was not included for the periods ended June 30, 1998 as their
effect would have been antidilutive. Harken has adopted Statement of Financial
Accounting Standards No. 128, "Earnings per Share", effective December 15,
1997, and as a result has restated 1997 weighted average shares outstanding
calculations, although there was no impact on prior year income per share
amounts. A reconciliation of the calculations of diluted earnings per common
share is as follows:

(10) INCOME TAXES

     At June 30, 1998, Harken had available for federal income tax reporting
purposes, net operating loss (NOL) carryforward for regular tax purposes of
approximately $60,000,000 which expires in 1998 through 2012, alternative
minimum tax NOL carryforward of approximately $51,000,000 which expires in 1998
through 2011, investment tax credit carryforward of approximately $842,000 which
expires in 1998 through 2002, statutory depletion carryforward of approximately
$2,400,000 which does not have an expiration date, and a net capital loss
carryforward of approximately $12,400,000 which expires in 2007 through 2011.
Approximately $16,000,000 of the net operating loss carryforward has been
acquired with the purchase of subsidiaries and must be used to offset future
income from profitable operations within those subsidiaries.

     Total deferred tax liabilities, relating primarily to property and
equipment, as of June 30, 1998 were approximately $680,000. Total deferred tax
assets, primarily related to the net operating loss carryforward, were
approximately $20,538,000 at June 30, 1998. The total net deferred tax asset is
offset by the valuation allowance of approximately $19,858,000 at June 30, 1998.


(11) RELATED PARTY TRANSACTIONS

     In June 1997, Harken added to its Board of Directors a new director who is
also a managing director of EnCap Investments L.C. ("EnCap"). EnCap has
historically provided financial consulting and investment banking services to
Harken. In connection with the June 1997 placement of the 5 1/2% European Notes,
EnCap received as a financial consulting fee, $466,667 in cash, and a warrant to
purchase 50,000 shares of Harken common stock at any time after December 11,
1997 and on or before December 11, 1999 at an exercise price of $5.00 per share.
As described in Note 6 -- Development Finance and Operating Agreements, in
October 1997, Harken entered into a Development Finance Agreement with the EnCap

                                       19
   20

Investors. EnCap serves as the general partner of three of the EnCap Investors
and the new Harken director serves as a director of the fourth EnCap Investor.
In connection with the EnCap Development Finance Agreement, EnCap received an
investment banking fee of $500,000. As described in Note 2--Acquisitions, in May
1998 Harken acquired the Bargo Properties from St. Martinville Partners, Ltd.
and Bargo Energy Company, which are affiliates of Encap.

     During 1997 and 1998, Harken made short-term loans totaling $355,000 to
certain members of Harken's Board of Directors and Management. Such notes
receivable are reflected in Harken's consolidated balance sheet at December 31,
1997 and June 30, 1998 as Related Party Notes Receivable.


(12) COMMITMENTS AND CONTINGENCIES

     Harken has accrued approximately $1,887,000 at June 30, 1998 relating to
operational or regulatory contingent liabilities related to Harken's domestic
operations. Harken and its subsidiaries currently are involved in various
lawsuits and other contingencies, including the guarantee of certain lease
obligations of a former subsidiary, which in management's opinion, will not
result in significant loss exposure to Harken.

     The exploration, development and production of oil and gas are subject to
various Navajo, federal and state laws and regulations designed to protect the
environment. Compliance with these regulations is part of Harken's day-to-day
operating procedures. Infrequently, accidental discharge of such materials as
oil, natural gas or drilling fluids can occur and such accidents can require
material expenditures to correct. Harken maintains levels of insurance customary
in the industry to limit its financial exposure. Management is unaware of any
material capital expenditures required for environmental control during the next
fiscal year.

OVERVIEW

     Harken reported net income for the six months ended June 30, 1998 of
$328,000 compared to a net income of $114,000 for the prior year period. Total
revenues increased from approximately $8.28 million during the six months ended
June 30, 1997 to approximately $9.26 million for the same period in 1998, due to
increased interest income as a result of net proceeds received from the issuance
of the 5 1/2% European Notes, the 5% European Notes and from three Development
Finance Agreements. Gross profit from both domestic and Colombia oil and gas
operations before depreciation and amortization, general and administrative and
interest expenses totaled approximately $2.6 million during the six months ended
June 30, 1998 compared to approximately $4.3 million for the prior year period.

     Internationally, during the second quarter of 1998, Harken reflected its
initial revenues from its Colombia operations, consisting of oil revenues from
Harken's Bolivar and Bocachico Contract Areas. During March 1998, Harken signed
an additional Association Contract in Colombia with Ecopetrol, bringing the
total number of Association Contracts to six and increasing the total number of
acres currently operated in Colombia by Harken to approximately 1,358,000.
Harken has continued its Colombian exploration efforts during the first part of
1998 with the drilling of the Estero #3 and Canacabare #1 wells on the Alcaravan
Contract area, the Catalina #1 and Olivo #1 wells on the Bolivar Contract area,
and the drilling of the Torcaz #5 well on the Bocachico Contract area.

     In the Alcaravan Contract area, Harken's operations have been affected by
the rainy season in the Llanos Basin, which will delay the completion and
testing of the recently drilled Canacabare #1 well until the fourth quarter of
1998. Despite weather conditions, Harken is now planning to begin in August 1998
the construction of the Phase I Pipeline connecting the Estero wells to the
closest existing pipeline. Harken also expects to initiate a long-term
production test of the Estero wells in August 1998, with an initial trucking
rate of 500 barrels of oil per day, which is expected to increase to 1,000
barrels of oil per day within thirty to sixty days. Construction and initial
operations of the Phase I Pipeline, pending weather conditions, are scheduled
to be completed in late 1998.

     An independent reservoir engineering firm estimates the Olivo #1 and the
Catalina #1 are each capable of producing at rates in excess of 20,000 barrels
of oil per day with larger production equipment. Harken anticipates initiating a
long-term production test by trucking from the Catalina #1 and Olivo #1 wells in
August 1998. Harken intends to submit its application to Ecopetrol for
commerciality of its Catalina, Olivo, Estero and Torcaz wells later in 1998 or
early 1999. In the Cambulos Contract area, Harken anticipates drilling its
first well 

                                       21
   22

on the Cambulos acreage, on the Emerald Mountain feature, in August 1998.
Harken plans to continue its Colombian exploration program during 1998,
expecting to spud seven additional exploratory wells in the Bolivar and Cambulos
Contract areas as well as certain pipeline and facility installation efforts,
including planned construction during the year of a Bolivar Association Contract
area pipeline and facility project to be completed and operational during the 
first half of 1999. The completion of this Bolivar pipeline and facility
project is expected to allow the initial transport of a maximum of 30,000 gross
barrels of oil and 150 million gross cubic feet of gas per day.

For the quarter ended June 30, 1998 compared with the corresponding prior
period.

DOMESTIC OPERATIONS

     Harken's domestic operations consist primarily of the operations in the
Four Corners area of Utah, Arizona and New Mexico, primarily on the Navajo
Indian Reservation, onshore South Texas, the Western and Panhandle regions of
Texas, the Magnolia region of Arkansas and the Carlsbad region of New Mexico,
and beginning in May 1998, the onshore region of southern Louisiana.

     Gross oil revenues decreased 32% to $1,346,000 during the second quarter of
1998 compared to $1,975,000 during the second quarter of 1997 primarily due to
the sharp decline in oil prices, which averaged $5.93 less per barrel during the
second quarter of 1998 compared to the prior year period. With the May 1998
acquisition of the Bargo Properties, Harken should begin to reflect production
volumes slightly higher than volumes produced in 1997. During the first half of
the third quarter of 1998, prices have continued to remain lower than prices
received during 1997.

     Gross gas revenues increased only slightly to $1,051,000 for the three
months ended June 30, 1998 compared to $1,037,000 for the prior year period,
with the increased production resulting from the acquisition of the Cal-T
Properties in August 1997 approximately offsetting the normal declines of
Harken's other domestic gas production. The slight increase in gas revenues was
also caused by the increase in average gas prices received during the second
quarter of 1998, as Harken received an overall average price of $2.19 per mcf of
gas production during the second quarter of 1997 compared to $2.24 per mcf
received during the second quarter of 1998.

                                       23
   24

     Oil and gas operating expenses consist of lease operating expenses and gas
plant expenses, along with a number of production and reserve based taxes,
including severance taxes, property taxes, Utah conservation taxes and Navajo
severance and possessory interest taxes. The increase in oil and gas operating
expenses compared to the prior year is primarily a result of the above mentioned
acquisitions of the Cal-T and Bargo Properties.

COLOMBIAN OPERATIONS

     In April 1998, Harken initiated trucking operations from its Torcaz #2 and
Torcaz #3 wells on the Bocachico Contract area. In addition, Harken sold
production which was generated during the drilling of the Catalina #1 and Olivo
#1 wells on the Bolivar Contract area. All sales volumes were transported using
trucking operations from the wellsite.

     Harken's Colombian oil revenues are expected to increase throughout the
remainder of 1998, particularly as production tests commence for the Catalina #1
and Olivo #1 wells beginning in August 1998. In addition, long-term production
tests of the Estero wells are also expected to begin in August 1998.

INTEREST AND OTHER INCOME

     Interest and other income increased significantly during the second quarter
of 1998 compared to the prior year period due to interest earned by Harken on
its invested funds, including the net proceeds from the June 1997 issuance of
$70 million of 5 1/2% European Notes, the May 1998 issuance of $85 million of 5%
European Notes and from proceeds from the EnCap Development Finance Agreement
and the European Development Finance Agreements. Harken generated approximately
$2.1 million of interest income during the second quarter of 1998, compared to
approximately $854,000 of interest income during the prior year period. Harken's
cash balances, which include investments in short-term marketable debt
securities, are expected to decrease in the second half of 1998 as such funds
are used to support Harken's capital expenditure plans, however, interest income
is expected to continue to be higher than the corresponding period of 1997.

OTHER COSTS AND EXPENSES

     General and administrative expenses increased 51% from $1,166,000 for the
second quarter of 1997 to $1,766,000 for the second quarter of 1998, related to
Harken's increased executive, corporate and administrative personnel costs
associated with Harken's expanding overall operations. In addition, Harken has
increased its corporate office space to accommodate the growth in personnel.

     Depreciation and amortization expense increased slightly during the second
quarter of 1998 compared to the prior year period due to the production from
Harken's Colombian operations. Depreciation and amortization on oil and gas
properties is calculated on a unit of production basis in accordance with the
full cost method of accounting for oil and gas properties. In addition, Harken's
depreciation on other property has increased as a result of Harken's expanding
operations.

     Interest expense and other decreased during the second quarter of 1998
compared to the prior year period despite the June 1997 issuance of the 5 1/2%
European Notes and the May 1998 issuance of the 5% European Notes due to the
increase in the amounts of interest capitalized to Harken's Colombian
exploration activity.

   25

For the six months ended June 30, 1998 compared with the corresponding prior
period.

     Gross oil revenues decreased 34% to $2,725,000 during the first six months
of 1998 compared to $4,135,000 during the first six months of 1997 primarily due
to the sharp decline in oil prices, which averaged $6.51 less per barrel during
the first six months of 1998 compared to the prior year period. During the first
half of the third quarter of 1998, prices have continued to remain lower than
prices received during 1997.

     Gross gas revenues decreased 4% to $2,240,000 for the six months ended June
30, 1998 compared to $2,344,000 for the prior year period, the increased
production resulting from the acquisition of the Cal-T Properties in August
1997. The decrease in gas revenues was partly caused by the decrease in average
gas prices received during the first six months of 1998, as Harken received an
overall average price of $2.70 per mcf of gas production during the first six
months of 1997 compared to $2.31 per mcf received during the first six months of
1998. Harken also reflected decreased gas production from certain of its Texas
Panhandle properties during the first quarter of 1998 as many of the properties
experienced numerous temporary operational curtailments.

     Oil and gas operating expenses consist of lease operating expenses and gas
plant expenses, along with a number of production and reserve based taxes,
including severance taxes, property taxes, Utah conservation taxes and Navajo
severance and possessory interest taxes. The increase in oil and gas operating
expenses compared to the prior year is primarily a result of the above mentioned
acquisition of the Cal-T and Bargo Properties.

COLOMBIAN OPERATIONS

     Harken initiated trucking operations for a ninety day production test from
its Bocachico Contract operations during the second quarter of 1998, and also
began sales of trucked volumes produced during the drilling of the Catalina #1
and Olivo #1 wells on the Bolivar Contract area. Harken expects to initiate
trucking of long-term test production from its Bolivar and Alcaravan Contract
operations in August 1998. In addition, 1998 production operations could further
increase if the current and planned drilling activities in Colombia are
successful. Harken reflected no oil and gas revenues or operating expenses from
its Colombian operations during the first quarter of 1998.

INTEREST AND OTHER INCOME

     Interest and other income increased significantly during the first six
months of 1998 compared to the prior year period due to interest earned by
Harken on its invested funds, including the net proceeds from the June 1997
issuance of $70 million of 5 1/2% European Notes, and the May 1998 issuance of
$85 million of 5% European Notes, and from proceeds from the EnCap Development
Finance Agreement and the European Development Finance Agreements. Harken
generated approximately $3.8 million of interest income during the first six
months of 1998, compared to approximately $1.4 million of interest income during
the prior year period. Harken's cash balances, which include investments in
short-term marketable debt securities, are expected to decrease in the second
half of 1998 as such funds are used to support Harken's capital expenditure
plans, however, interest income is expected to continue to be higher than the
corresponding period of 1997.

                                       25
   26

OTHER COSTS AND EXPENSES

     General and administrative expenses increased 41% from $2,500,000 for the
first six months of 1997 to $3,524,000 for the first six months of 1998, related
to Harken's increased executive, corporate and administrative personnel costs
associated with Harken's expanding overall operations. In addition, Harken has
increased its corporate office space to accommodate the growth in personnel.

     Depreciation and amortization expense increased slightly during the first
six months of 1998 compared to the prior year period consistent with the
increased equivalent barrel production levels during the period. Depreciation
and amortization on oil and gas properties is calculated on a unit of production
basis in accordance with the full cost method of accounting for oil and gas
properties. In addition, Harken's depreciation on other property has increased
as a result of Harken's expanding operations.

     Interest expense and other decreased significantly during the first six
months of 1998 compared to the prior year period despite the June 1997 issuance
of the 5 1/2% European Notes and the May 1998 issuance of the 5% European Notes
due to the increase in the amounts of interest capitalized to Harken's Colombian
exploration activity.


                         LIQUIDITY AND CAPITAL RESOURCES

     Harken's working capital at June 30, 1998 was approximately $178.8 million,
versus approximately $110.6 million at December 31, 1997. The increase in cash
and working capital resulted primarily from approximately $81.8 million of net
proceeds from the 5% European Notes issued in May 1998 and from the receipt of
approximately $9.8 million pursuant to Development Finance Agreements. In
addition, Harken's operations provided approximately $2.4 million of cash flow
during the first six months of 1998. Such activity was sufficient to fund
capital expenditures of approximately $46 million during the first six months of
1998. 

     Harken's primary need for capital is to fund the planned exploration and
development efforts in Colombia. In 1997, Harken's capital expenditures totaled
approximately $37 million, including $30 million related to exploration and
development in Colombia. Harken anticipates that its 1998 Colombian capital
expenditures will total approximately $112 million. Harken believes that it will
have sufficient cash resources to fund all of its planned capital expenditures
for 1998. In addition, Harken intends to continue to pursue domestic acquisition
opportunities during 1998. Harken intends to fund such acquisitions, if any are
consummated, through a combination of cash on hand, issuances of debt or equity
securities.

     Harken anticipates that full development of its Colombian reserves will
take several years and will also require extensive production facilities,
transportation pipelines and development activity which will require significant
additional capital expenditures. The ultimate amount of such expenditures cannot
be presently predicted. As a result of its recent successes in Colombia from its
exploratory drilling program, Harken's current business plan includes estimated
total capital expenditures in Colombia for the years 1998 through 2001 that
approximate $1 billion. Harken estimates that approximately 75 to 80% of
external funds applicable to these capital expenditures will be provided from
non-recourse project finance and other similar forms of debt which can be
identified to specific development projects. Harken anticipates it would put
this type of debt facility in place after establishing ongoing production rates
from its recently announced discoveries. There can be no assurances, however,
that Harken will have adequate funds available to it to fund all of its
Colombian activities.

     Terms of each of the Association Contracts entered into between Harken de
Colombia, Ltd. and Ecopetrol commit Harken to perform certain activities in
accordance with a prescribed timetable. Failure by Harken to perform these
activities as required could result in Harken losing its rights under the
particular Association Contract, which could potentially have a material adverse
effect on Harken's business.

     Harken's domestic operating strategy includes efforts to acquire additional
oil and gas reserves through drilling activities in North America and through
acquisitions. Harken plans to continue development of proved undeveloped
reserves on its North American properties in addition to a continual workover
program on producing properties. Harken expects such drilling and workover costs
to total approximately $4 million in 1998. The targeted results of these efforts
are to maintain North American production levels during 1998.

     On May 26, 1998, Harken issued a total of $85 million in 5% Senior
Convertible Notes (the "European Notes") which mature on May 26, 2003. In
connection with the sale and issuance of the 5% European Notes, Harken paid
approximately $4,256,000 from the 5% European Notes proceeds for commission and
issuance costs. Interest incurred on these notes is payable semi-annually in May
and November of each year to maturity or until the 5% European Notes are
converted. Such European Notes are convertible into shares of Harken common
stock at a conversion price of $6.50 per share, subject to adjustment in certain
circumstances. Harken also has the right to require conversion of the 5%
European Notes into shares of Harken common stock at any time on or after May
26, 1999, if for any period of thirty consecutive days commencing on or after
May 26, 1998, the average of the closing prices of Harken common stock for each
trading day during such thirty-day period shall have equaled or exceeded 125% of
the 5% European Note Conversion Price (or $8.125 per share of Harken common
stock).

     All proceeds from the sale of previous European Notes issuances were
initially paid to a Trustee pursuant to a Trust Indenture and held in Segregated
Accounts to be maintained for Harken's benefit. In order for any of the proceeds
to be released from the Segregated Accounts, Harken was required to demonstrate
that an Asset Value Coverage Ratio (as defined in the Trust Indenture) test
would continue to be met after such release of funds. At June 30, 1998, all
proceeds held in the Segregated Accounts had been released following the
conversion of these European Notes into shares of Harken common stock. There is
no Segregated Account requirement related to the proceeds from the 5% European
Notes. For a detailed discussion of the 5% European Notes see "Notes to
Consolidated Financial Statements, Note 7 -- European Convertible Notes
Payable."

     Interest payments related to the 5% European Notes will be funded from cash
flow from operations or existing cash balances.

     In October 1997, December 1997, and March 1998, Harken entered into
separate Development Finance Agreements with institutional investors
(collectively the "Institutional Investors"), pursuant to which the
Institutional Investors provided approximately $34.5 million (the "Payment
Amount") of net proceeds to Harken to finance the drilling of the initial wells
on three unexplored oil and gas prospects in the Middle Magdalena Basin of
Colombia. Approximately $24.5 million of net proceeds was received in October
1997 and approximately $10 million of net proceeds was received during the first
quarter of 1998. In exchange, the Institutional Investors obtained the right to
receive future payments from Harken equal to 7% of the net profits that Harken
de Colombia, Ltd. may derive from the sale of oil and gas produced from each of
the three prospects if the planned drilling on the prospect is successful (the
"Institutional Participation"). Pursuant to the Development Finance Agreements,
Harken is obligated to drill each of the three wells prior to October 2000.

     Pursuant to the Development Finance Agreements, the Institutional Investors
have the right, for a period of two years beginning in October 1998, to convert
all or part of the Institutional Participation into shares of Harken common
stock. The number of shares of Harken common stock to be issued upon conversion
of the Institutional Participation will be equal to the quotient of (i) the
Payment Amount (less any distributions made in respect of the Institutional
Participation) plus an amount equal to 15% interest per annum on the net Payment
Amount compounded monthly (the "Invested Amount"), divided by (ii) the market
price of the Harken common stock at the time of conversion. During the same two
year period, Harken also has the right to convert the Institutional
Participation into shares of Harken common stock with the number of shares of
Harken common stock to be issued to be equal to the quotient of (i) the Payment
Amount (less any distribution made in respect of the Institutional
Participation) plus an amount equal to 25% interest per annum on the net Payment
Amount compounded monthly, divided by (ii) the market price of Harken common
stock at the time of conversion. Harken can also elect to pay cash upon any
conversion of the Institutional Participation in lieu of issuing Harken common
stock. The Development Finance Agreements also provide for additional shares of
Harken common stock to be issued by Harken in the event of a conversion to the
extent that the Institutional Investors do not, under certain circumstances,
realize the Invested Amount from the sale of shares of Harken common stock
issued at the conversion.

     At the present time, it is not known whether the Institutional Investors or
Harken will exercise their rights to convert the Institutional Interest into
Harken common stock, nor can Harken determine the number of shares of Harken
common stock which would be required to be issued in the event that Harken or
the Institutional Investors elect to convert the Institutional Participation
into shares of Harken common stock.

     On April 9, 1998, Harken entered into a Securities Purchase Agreement with
RGC International Investors, LDC ("RGC"), pursuant to which Harken issued to RGC
15,000 shares of its Series F Convertible Preferred Stock (the "Series F
Preferred") in exchange for $15,000,000. The Series F Preferred is convertible
into shares of Harken common stock at a conversion price based upon the market
price of Harken common stock at the time of conversion. The number of shares of
Harken common stock issuable upon conversion of the Series F Preferred will also
include a premium amount equal to an increase calculated on the face value of
the Series F Preferred at 5% per annum. The Series F Preferred does not pay
dividends.

     Harken has the option to redeem for cash any shares of Series F Preferred
presented for conversion if (a) prior to January 9, 1999, the closing price of
Harken common stock on the conversion date is less than $4.80, or (b) on or
after January 9, 1999, the then applicable conversion price is less than $4.80,
for an amount equal to the number of shares of Harken common stock that would
otherwise be issuable upon conversion multiplied by the closing price of Harken
common stock on the conversion date.

     At each election to convert shares of Series F Preferred into Harken common
stock, RGC will have the option to purchase from Harken for cash additional
shares of Harken common stock equal to the number of shares issued on such
conversion (less any shares issued in respect of the premium amount) at a
purchase price equal to the then applicable conversion price. For a detailed
discussion of the Series F Preferred see "Notes to Consolidated Financial
Statements, Note 8--Stockholders' Equity".

     The exploration, development and production of oil and gas are subject to
various Colombian, Navajo, federal, state and local laws and regulations
designed to protect the environment. Compliance with these regulations is part
of Harken's day-to-day operating procedures. Accidental discharge of such
materials as oil, natural gas or drilling fluids can occur and such accidents
can require material expenditures to correct. Harken maintains levels of
insurance customary in the industry to limit its financial exposure. Management

                                       28

is unaware of any material capital expenditures required for environmental
control during the next fiscal year.

     Harken has accrued approximately $1.9 million at June 30, 1998 relating to
operational or regulatory contingent liabilities related to Harken's domestic
operations. Harken and its subsidiaries currently are involved in various
lawsuits and other contingencies, which in management's opinion, will not result
in significant loss exposure to Harken.

                           PART II - OTHER INFORMATION

Item 1.  Legal Proceedings.

         In September 1997, Harken Exploration Company, a wholly-owned
         subsidiary of Harken, was served with a lawsuit filed in Amarillo,
         Texas in Federal District Court for the Northern District of Texas
         styled D. E. Rice and Karen Rice, as Trustees for the Rice Family
         Living Trust vs. Harken Exploration Company. The Rice Family Living
         Trust ("Rice") is a surface land owner in Hutchinson County, Texas.
         Rice has alleged that oil and saltwater spills from Harken Exploration
         Company's equipment and wells have polluted and otherwise damaged its
         property. Rice is seeking payment of costs to prevent, minimize and
         mitigate the alleged oil pollution, costs to restore and repair the
         land and vegetation, costs to decontaminate the ground and surface
         water, interest, attorneys' fees, and punitive damages. Furthermore,
         Rice has requested that Harken Exploration Company be enjoined from
         producing any oil or gas from its lands. Rice has alleged that
         remediation of all of the pollution on its land will cost approximately
         $40,000,000. Harken believes that this lawsuit is wholly without merit.
         Harken has filed a Motion to Dismiss for Failure to State a Claim and
         has asserted numerous other defenses, all of which Harken believes are
         meritorious. Harken intends to defend itself vigorously.

         Harken and its subsidiaries currently are involved in various other
         lawsuits and other contingencies, which in management's opinion, will
         not have a material adverse effect on Harken's financial position.

Item 2.  Changes in Securities.

         In April 1998, Harken adopted a Stockholder Rights Plan. For further
         discussion, see Harken's Current Report on Form 8-K dated April 6,
         1998.

Item 3.  Default Upon Senior Securities.

         Not applicable.

Item 4.  Submission of Matters to a Vote of Securities Holders.

         On June 11, 1998, Harken held its Annual Meeting of Stockholders. At
