         operations, borrowings from financial institutions and the sale of debt
         and equity securities. At June 30, 2003, the Company had $5.0 million
         of availability under its Credit Facility with Wachovia Bank, National
         Association, as Administrative Agent (the "Credit Facility"). The
         Credit Facility matures June 30, 2004 and accordingly, the balance
         outstanding under the Credit Facility on June 30, 2003 of $70 million
         is classified as a current liability on the Company's Consolidated
         Balance Sheet as of June 30, 2003. The Company plans to enter into
         negotiations to secure a new Credit Facility. The Company also is
         reviewing financing alternatives that address the maturity of all its
         debt.

         Non-discretionary capital expenditures planned for the second half of
         2003 include the development of the Medusa and Habanero deepwater
         discoveries, currently scheduled to begin production in October 2003.
         The Company anticipates that cash flow generated during 2003 and the
         current availability under the Credit Facility will provide necessary
         capital to complete the development of these discoveries and fund other
         discretionary projects. The Company is also considering alternate
         funding for the costs associated with development of the deepwater
         discoveries.

         The Company anticipates that the cash flow from these discoveries and
         borrowing capacity provided by the associated proved producing reserves
         being integrated into the borrowing base of the Company's Credit
         Facility will provide funds for future exploration and development
         activities.

         Beginning in October 2002, the Company received a series of inquiries
         from the SEC regarding its Annual Report on Form 10-K for the year
         ended December 31, 2001 requesting supplemental information concerning
         operations in the Gulf of Mexico. The comment letters requested

                                       6


         information about the procedures used to classify the deepwater
         reserves as proved and requested that the financials be restated to
         reflect the removal of the reserves attributable to the Boomslang
         discovery as proved for all prior periods during which such reserves
         were reported as proved. The Company has reviewed the SEC comments with
         its independent petroleum reserve engineers, Huddleston & Co., Inc. of
         Houston, Texas. Both Huddleston & Co. and Callon believe that such
         deepwater reserves are properly classified as proved. Discussions with
         the SEC are ongoing at this time.

         ACCOUNTING PRONOUNCEMENTS

         In June 2001, the Financial Accounting Standards Board ("FASB") issued
         Statement of Financial Accounting Standards No. 143, Accounting for
         Asset Retirement Obligations, ("SFAS 143") effective for fiscal years
         beginning after June 15, 2002. As more fully discussed in Note 2 to the
         consolidated financial statements included in Callon's 2002 Annual
         Report, SFAS 143 essentially requires entities to record the fair value
         of a liability for legal obligations associated with the retirement of
         tangible long-lived assets and the associated asset retirement costs.
         Callon adopted the statement on January 1, 2003 resulting in a
         cumulative effect of accounting change of $181,000, net of tax. See
         Note 6.

         In December 2002, the FASB issued SFAS No. 148, Accounting for
         Stock-Based Compensation-Transition and Disclosure - an amendment of
         FASB Statement No. 123 ("SFAS 148"). This statement provides
         alternative methods of transition for a voluntary change to the fair
         value based method of accounting for stock-based employee compensation,
         along with the requirement of disclosure in both annual and interim
         financial statements about the method of accounting for stock-based
         compensation and the effect on reported results. See Note 7.

         In January 2003, the FASB issued Interpretation No. 46, "Consolidation
         of Variable Interest Entities, an Interpretation of Accounting Research
         Bulletin (ARB) 51" ("FIN 46"). FIN 46 addresses consolidation by
         business enterprises of variable interest entities ("VIEs"). The
         primary objective of FIN 46 is to provide guidance on the
         identification of, and financial reporting for, entities over which
         control is achieved through means other than voting rights; such
         entities are known as VIEs. This guidance applies immediately to VIEs
         created after January 31, 2003, and July 1, 2003 for VIEs existing
         prior to February 1, 2003. The Company believes there will be no impact
         on the financial statements as a result of the adoption of FIN 46.

2.       PER SHARE AMOUNTS

         Basic earnings or loss per common share were computed by dividing net
         income or loss by the weighted average number of shares of common stock
         outstanding during the period. Diluted earnings or loss per common
         share were determined on a weighted average basis using common shares
         issued and outstanding adjusted for the effect of common stock
         equivalents computed using the treasury stock method and the effect of
         the convertible preferred stock (if dilutive). The conversion of the
         preferred stock was not included in the calculation for the three-month
         and six-month periods ended June 30, 2003 and 2002 due to the
         antidilutive effect on income or loss per share.

3.       DERIVATIVES

         The Company periodically uses derivative financial instruments to
         manage oil and gas price risk. Settlements of gains and losses on
         commodity price contracts are generally based upon the difference
         between the contract price or prices specified in the derivative
         instrument and a NYMEX price or other cash or futures index price.

         In 2003 and 2002, the Company purchased and sold various derivatives
         including put options and call options and elected not to designate
         these derivative financial instruments as accounting hedges and
         accordingly, accounted for these contracts under mark-to-market
         accounting. In the second quarter of 2003 and 2002, the Company
         recognized charges to expense of $171,023 and $381,950, respectively,
         to record changes in fair value of these contracts. Year-to-date losses
         were $479,869 and $769,950, respectively, through June 30, 2003 and
         2002. There were no derivatives of this type remaining at June 30,
         2003.

         During 2002, the Company entered into no-cost natural gas collar
         contracts in effect for February 2003 through October 2003. Remaining
         open collar contracts at June 30, 2003 are for volumes of 250,000 Mcf
         per month from July through October, with an average ceiling price of
         $4.76 and a floor price of $3.50. These contracts are accounted for as
         cash flow hedges under SFAS 133. The Company recognized a loss of
         $770,900 and $2,613,250 in oil and gas sales related to the maturity of
         such collars in the three-month and six-month periods ended June 30,
         2003, respectively. The fair value of remaining collar contracts at
         June 30, 2003 is recorded in the balance sheet as a current liability
         of $852,650.


                                       8



         During 2003, the Company entered into additional no-cost natural gas
         collar contracts in effect for May 2003 through October 2003. These
         agreements were for volumes of 200,000 Mcf per month with a ceiling
         price of $5.80 and a floor price of $5.00. The company elected not to
         designate these derivative financial instruments as accounting hedges
         and accordingly, accounted for these contracts under mark-to-market
         accounting. For the three-month and six-month periods ended June 30,
         2003, the Company recognized a loss of approximately $224,000 and
         $53,600, respectively, to record the change in the fair value of these
         contracts. The fair value of these collar contracts at June 30, 2003
         was a current liability of $53,600.

         In 2001, the Company entered into derivative contracts for 2002
         production with Enron North America Corp. ("Enron"). In the fourth
         quarter of 2001, the Company charged to expense (non-cash) $9.2 million
         representing the fair market value of these derivatives as of September
         30, 2001. As the contracts matured, the Company recorded non-cash
         revenue each month. For the three-month and six-month periods ended
         June 30, 2002, the Company recorded approximately $2.3 million and $5.3
         million, respectively, as non-cash oil and gas revenues. Also, in the
         second quarter of 2002, the Company completed the sale of its claims
         against Enron for $2.5 million and reported a pre-tax gain of that
         amount.

         Borrowings outstanding at June 30, 2003 under the Credit Facility
         totaled $70.0 million with $5.0 million of borrowings available. The
         borrowing base under the Credit Facility, which is re-determined
         periodically, is based on an amount established by the bank group after
         its evaluation of our proved oil and gas reserve values. The Credit
         Facility has a maturity date of June 30, 2004 and has been reclassified
         as a current liability.

6.       ASSET RETIREMENT OBLIGATIONS

         As discussed in Note 1, the Company adopted SFAS 143 on January 1,
         2003. The impact of adopting the statement resulted in a gain of
         $181,000, net of tax, which is reported as a cumulative effect of
         change in accounting principle.

         Approximately $30.3 million was recorded as the present value of asset
         retirement obligations on January 1, 2003 with the adoption of SFAS 143
         related to the Company's oil and gas properties. Changes to the present
         value of the asset retirement obligations due to the passage of time
         are recorded as accretion expense in the Consolidated Statements of
         Operations.

         Assets, primarily U.S. Government securities, of approximately $7.0
         million at June 30, 2003, are recorded as restricted investments. These
         assets are held in abandonment trusts dedicated to pay future
         abandonment costs of oil and gas properties in which the Company has
         sold a net profits interest. If there is any excess of trust assets
         over abandonment costs, the excess will be distributed to the net
         profits interest owners.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS

FORWARD-LOOKING STATEMENTS

This report includes "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. All statements other than statements of historical facts included in
this report, including statements regarding the Company's financial position,
adequacy of resources, estimated reserve quantities, business strategies, plans,
objectives and expectations for future operations and covenant compliance, are
forward-looking statements. The Company can give no assurances that the
assumptions upon which such forward-looking statements are based will prove to
have been correct. Important factors that could cause actual results to differ
materially from the Company's expectations ("Cautionary Statements") are
disclosed below, in the section entitled "Risk Factors" included in the
Company's Annual Report on Form 10-K for the Company's most recent fiscal year,
elsewhere in this report and from time to time in other filings made by the
Company with the Securities and Exchange Commission. All subsequent written and
oral forward-looking statements attributable to the Company or persons acting on
its behalf are expressly qualified by the Cautionary Statements.

GENERAL

The Company's revenues, profitability, future growth and the carrying value of
its oil and gas properties are substantially dependent on prevailing prices of
oil and gas and its ability to find, develop and acquire additional oil and gas
reserves that are economically recoverable and its ability to develop existing
proved undeveloped reserves. The Company's ability to maintain or increase its
borrowing capacity and to obtain additional capital on attractive terms is also
influenced by oil and gas prices. Prices for oil and gas are subject to large
fluctuations in response to relatively minor changes in the supply of and demand
for oil and gas, market uncertainty and a variety of additional factors beyond
the control of the Company. These factors include weather conditions in the
United States, the condition of the United States economy, the actions of the
Organization of Petroleum Exporting Countries, governmental regulations,
political stability in the Middle East and elsewhere, the foreign supply of oil
and gas, the price of foreign imports and the availability of alternate fuel
sources. Any substantial and extended decline in the price of oil or gas would
have an adverse effect on the Company's carrying value of its proved reserves,
borrowing capacity, revenues, profitability and cash flows from operations. The
Company uses derivative financial instruments for price protection purposes on a
limited amount of its future production but does not use derivative financial
instruments for trading purposes.

The following discussion is intended to assist in an understanding of the
Company's historical financial positions and results of operations. The
Company's historical financial statements and notes thereto included elsewhere
in this quarterly report contain detailed information that should be referred to
in conjunction with the following discussion.

LIQUIDITY AND CAPITAL RESOURCES

The Company's primary sources of capital are its cash flows from operations,
borrowings from financial institutions and the sale of debt and equity
securities. At June 30, 2003, the Company had $5.0 million of availability under
its Credit Facility. Net cash and cash equivalents during the six months ended

                                       13


June 30, 2003 decreased by $0.9 million and cash provided by operating
activities totaled $23.9 million. Net capital expenditures for the period
totaled $24.7 million.

In 2002, the lenders under the Company's Credit Facility agreed to increase
availability under the revolving borrowing base from $50 million to $75 million.
The Credit Facility matures June 30, 2004 and accordingly, the balance
outstanding under the Credit Facility on June 30, 2003 of $70 million is
classified as a current liability on the Company's Consolidated Balance Sheet as
of June 30, 2003. The Company plans to enter into negotiations to secure a new
Credit Facility. The Company also is reviewing financing alternatives that
address the maturity of all its debt.

Non-discretionary capital expenditures planned for the second half of 2003
include the development of the Medusa and Habanero deepwater discoveries,
currently scheduled to begin production in October 2003. The Company anticipates
that cash flow generated during 2003 and the current availability under the
Credit Facility will provide necessary capital to complete the development of
these discoveries and fund other discretionary projects. The Company is also
considering alternate funding for the costs associated with development of the
deepwater discoveries.

The Company anticipates that the cash flow from these discoveries and borrowing
capacity provided by the associated proved producing reserves being integrated
into the borrowing base of the Company's Credit Facility will provide funds for
future exploration and development activities.

The completion of the Company's deepwater discoveries requires the construction
of expensive production facilities and pipelines, including the transportation,
installation and hookup of production facilities and the use of sub sea
completion techniques. The Company cannot estimate the timing of the
construction and hookup of these facilities with certainty. The operators
completing these discoveries will possibly face inclement weather and other
unfavorable environmental conditions, delays in fabrication and delivery of
necessary equipment, and other unforeseen circumstances that may delay
completion of these properties. Long-term delays in the completion of these
deepwater projects that prevent the commencement of production from such
discoveries could have a material adverse effect on the Company's financial
position and result of operations. Such a delay may require the Company to
reduce future anticipated capital expenditures or seek additional sources of
liquidity to finance capital expenditures, which may not be available.

Beginning in October 2002, the Company received a series of inquiries from the
SEC regarding its Annual Report on Form 10-K for the year ended December 31,
2001 requesting supplemental information concerning operations in the Gulf of
Mexico. The comment letters requested information about the procedures used to
classify the deepwater reserves as proved and requested that the financials be
restated to reflect the removal of the reserves attributable to the Boomslang
discovery as proved for all prior periods during which such reserves were
reported as proved. The Company has reviewed the SEC comments with its
independent petroleum reserve engineers, Huddleston & Co., Inc. of Houston,
Texas. Both Huddleston & Co. and Callon believe that such deepwater reserves are
properly classified as proved. Discussions with the SEC are ongoing at this
time.

CAPITAL EXPENDITURES

Capital expenditures for exploration and development costs related to oil and
gas properties totaled approximately $24.7 million in the first six months of
2003. The Company incurred approximately $13.3 million in the Gulf of Mexico
Deepwater Area primarily for development costs at the Company's Habanero and
Medusa discoveries. Interest of approximately $2.5 million and general and
administrative costs allocable directly to exploration and development projects
of approximately $4.4 million were capitalized for the first six months of 2003.
The Gulf of Mexico Shelf Area expenditures account for the remainder of the
total capital expended and were primarily associated with the Ship Shoal Blocks
28/35 development.

For the remainder of the year, the Company will continue evaluating property
acquisitions and drilling opportunities. The Company has forecast up to $31
million in capital expenditures for the remainder of 2003. The major portion of
the capital expenditure budget will be used for development of the Company's
Medusa and Habanero discoveries and the drilling of three deepwater prospects of
which two are located in the Medusa area. Discretionary projects of
approximately $5 million may be added based on liquidity and other
considerations.

COMPARISON OF RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 2003 AND
THE THREE MONTHS ENDED JUNE 30, 2002.

Oil and Gas Production and Revenues

Total oil and gas revenues increased 20% from $15.3 million in the second
quarter of 2002 to $18.4 million in the second quarter of 2003. Oil and gas
prices were substantially higher when compared to the same period in 2002 and
accounted for the increase in revenue. Oil and gas revenues for the second
quarter of 2002 included $2.3 million related to the Enron derivatives referred
to in Note 3 to the Consolidated Financial Statements.

Total production for the second quarter of 2003 decreased by 12% versus the
second quarter of 2002.

Gas production during the second quarter of 2003 totaled 3.2 Bcf and generated
$17.2 million in revenues compared to 3.6 Bcf and $13.9 million in revenues
during the same period in 2002. The average gas prices for the second quarter of
2003 averaged $5.44 per Mcf compared to $3.25 per Mcf for the same period last
year. The decrease in production in the second quarter of 2003 compared to the
second quarter of 2002 was due primarily to the sale of the North and Northwest
Dauphin Island fields in the fourth quarter of 2002 and normal and expected
declines in production from older properties.

Oil production during the second quarter of 2003 totaled 46,000 barrels and
generated $1.2 million in revenues compared to 60,000 barrels and $1.4 million
in revenues for the same period in 2002. Average oil prices received in the
second quarter of 2003 were $26.59 per barrel compared to $23.41 per barrel in
2002. The decrease in production in the second quarter of 2003 compared to the
second quarter of 2002 was due primarily to downtime for maintenance to the
facility and equipment at the Big Escambia Creek Field operated by ExxonMobil
Corporation and normal and expected declines in production from older
properties.

Lease Operating Expenses

Lease operating expenses, for the three-month period ending June 30, 2003
decreased to $2.5 million compared to $2.8 million for the same period in 2002.
The 10% decrease was due primarily to the sale of the North and Northwest
Dauphin Island fields in the fourth quarter of 2002.

Depreciation, Depletion and Amortization

Depreciation, depletion and amortization for the three months ending June 30,
2003 and 2002 were $7.0 million and $6.5 million, respectively. The 7% increase
was due primarily to the downward reserve revisions at Boomslang at the end of
2002. This decrease in estimated proved reserves, over which depletable costs
are amortized, increased the per unit depletion rate.

Accretion Expense

Accretion expense of $727,000 represents accretion for Callon's asset retirement
obligations for the second quarter of 2003.

                                       17



General and Administrative

General and administrative expenses, net of amounts capitalized, increased
slightly to $1.4 million from $1.3 million for the three-month periods ended
June 30, 2003 and June 30, 2002, respectively. The 8% increase was primarily due
to legal fees and directors' and officers' insurance expense.

Interest Expense

Interest expense increased by 26% to $7.5 million during the three months ended
June 30, 2003 from $5.9 million during the three months ended June 30, 2002.
This is a result of higher debt levels.

COMPARISON OF RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2003 AND
THE SIX MONTHS ENDED JUNE 30, 2002.

Oil and Gas Production and Revenues

Total oil and gas revenues increased 50% from $26.4 million in the first half of
2002 to $39.7 million in the first half of 2003. Oil and gas prices were
substantially higher when compared to the same period in 2002 and accounted for
the increase in revenue. Oil and gas revenues for the first half of 2002
included $5.3 million related to the Enron derivatives referred to in Note 3 to
the Consolidated Financial Statements.

Total production for the first half of 2003 decreased by 2% versus the first
half of 2002.

Gas production during the first half of 2003 totaled 6.6 Bcf and generated $37.1
million in revenues compared to 6.6 Bcf and $23.9 million in revenues during the
same period in 2002. Average gas prices received for the first half of 2003
averaged $5.62 per Mcf compared to $2.83 per Mcf during the same period last
year.

Oil production during the first half of 2003 totaled 91,000 barrels and
generated $2.6 million in revenues compared to 114,000 barrels and $2.4 million
in revenues for the same period in 2002. Average oil prices received in the
first half of 2003 were $28.93 per barrel compared to $21.16 per barrel in the
first half of 2002. The decrease in production was primarily due to downtime for
maintenance to the facility and equipment at the Big Escambia Creek Field
operated by ExxonMobil Corporation and normal and expected declines in
production from older properties.

Lease Operating Expenses

Lease operating expenses, for the six-month period ending June 30, 2003
decreased slightly by 1% to $5.3 million compared to $5.4 million for the same
period in 2002. The sale of North and Northwest Dauphin Island fields in the
fourth quarter of 2002 reduced lease operating expenses for this period.
However, this was offset by increased lease operating expenses for the Mobile
Block 864 area due to the implementation of the acceleration program in the
second quarter of 2002.

                                       18



Depreciation, Depletion and Amortization

Depreciation, depletion and amortization for the six months ending June 30, 2003
and 2002 were $14.4 million and $12.1 million, respectively. The 19% increase
was due primarily to the downward reserve revisions at Boomslang at the end of
2002. This decrease in estimated proved reserves, over which depletable costs
are amortized, increased the per unit depletion rate.

Accretion Expense

Accretion expense of $1.4 million represents accretion for Callon's asset
retirement obligations for the six-month period ended June 30, 2003.

General and Administrative

General and administrative expenses, net of amounts capitalized, increased by 8%
to $2.6 million during the six months ended June 30, 2003 from $2.4 million
during the six months ended June 30, 2002. The increase was primarily due to
legal fees and directors' and officers' insurance expense.

Interest Expense

Interest expense increased by 26% to $14.7 million during the six months ended
June 30, 2003 from $11.6 million during the six months ended June 30, 2002. This
is a result of higher debt levels.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's revenues are derived from the sale of its crude oil and natural
gas production. The prices for oil and gas remain extremely volatile and
sometimes experience large fluctuations as a result of relatively small changes
in supply, weather conditions, economic conditions and government actions. From
time to time, the Company enters into derivative financial instruments (forward
sales or swaps) to hedge oil and gas price risks for the production volumes to
which the hedge relates. The hedges reduce the Company's exposure on the hedged
volumes to decreases in commodity prices and limit the benefit the Company might
otherwise have received from any increases in commodity prices on the hedged
volumes. The Company from time to time has acquired puts which reduce the
Company's exposure to decreases in commodity prices while allowing realization
of the full benefit from any increases in commodity prices.

The Company also enters into price "collars" to reduce the risk of changes in
oil and gas prices. Under these arrangements, no payments are due by either
party so long as the market price is above the floor price set in the collar and
below the ceiling. If the price falls below the floor, the counter-party to the
collar pays the difference to the Company and if the price is above the ceiling,
the counter-party receives the difference from the Company.

The Company enters into these various agreements from time to time to reduce the
effects of volatile oil and gas prices and does not enter into hedge
transactions for speculative purposes. However, certain of the Company's
positions may not be designated as hedges for accounting purposes.

See Note 3 to the Consolidated Financial Statements for a description of the
Company's hedged position at June 30, 2003. There have been no significant
changes in market risks faced by the Company since the end of 2002.

                                       20



ITEM 4. CONTROLS AND PROCEDURES

     (a)  Evaluation of Disclosure Controls and Procedures. Based on their
evaluation as of the end of the period covered by this Quarterly Report on Form

"Exchange Act") are effective to ensure that information required to be
disclosed by the Company in reports that it files or submits under the Exchange
Act is recorded, processed, summarized and reported within the time periods
specified in the rules and forms of the Securities and Exchange Commission.

     (b)  Changes in Internal Controls. There were no significant changes in the
Company's internal controls or in other factors that could significantly affect
these controls subsequent to the date of their evaluation, including any
corrective actions with regard to significant deficiencies and material
weaknesses.
