Prospectus

                            CALLON PETROLEUM COMPANY

OFFER TO EXCHANGE ITS 10.125% SERIES B SENIOR SUBORDINATED NOTES DUE 2002 THAT
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 FOR ANY AND ALL OF ITS
OUTSTANDING 10.125% SERIES A SENIOR SUBORDINATED NOTES DUE 2002

          The Exchange Offer and Withdrawal Rights will expire at 5:00
             P.M., New York City time, on November 10, 1997, unless
                        extended (the "Expiration Date")
    
      Callon Petroleum Company, a Delaware corporation (the "Company" or
"Callon"), hereby offers, upon the terms and subject to the conditions set forth
in this Prospectus (as the same may be amended or supplemented from time to
time, the "Prospectus") and in the accompanying Letter of Transmittal (which
together constitute the "Exchange Offer"), to exchange up to $36,000,000
aggregate principal amount of its 10.125% Series B Senior Subordinated Notes due
2002 (the "Exchange Notes") that have been registered under the Securities Act
of 1933, as amended (the "Securities Act"), pursuant to a Registration Statement
(as defined) of which this Prospectus constitutes a part, for a like principal
amount of its outstanding 10.125% Series A Senior Subordinated Notes due 2002
(the "Outstanding Notes" and, together with the Exchange Notes, the "Notes"), of
which $36,000,000 aggregate principal amount is outstanding.

      The terms of the Exchange Notes are identical in all material respects to
the terms of the Outstanding Notes, except that (i) the Exchange Notes have been
registered under the Securities Act and therefore will not be subject to certain
restrictions on transfer applicable to the Outstanding Notes and generally will
not be entitled to registration rights, and (ii) the Exchange Notes will not
provide for any increase in the interest rate thereon related to such
registration rights. In that regard, the Outstanding Notes provide that if an
(i) exchange offer registration statement or resale shelf registration statement
is not filed by October 1, 1997 or (ii) exchange offer registration statement is
not declared effective by November 15, 1997, Special Interest (as defined) will
accrue and be payable semi-annually until such time as an exchange offer
registration statement is filed or becomes effective, as the case may be. In
addition, (i) if an exchange offer is not consummated or a resale shelf
registration statement is not declared effective by December 31, 1997 or (ii) if
either the exchange offer registration statement or the resale shelf
registration statement has been declared effective and such registration
statement ceases to be effective or usable (subject to certain exceptions),
Special Interest will accrue and be payable quarterly until such time as an
exchange offer is consummated or a resale shelf registration statement is
declared effective, as the case may be. See "Description of the Exchange Notes"
and "Description of the Outstanding Notes." The Exchange Notes are being offered
for exchange in order to satisfy certain obligations of the Company under the
Registration Agreement dated July 31, 1997 (the "Registration Agreement")
between the Company and the Initial Purchaser (as defined) of the Outstanding
Notes. The Exchange Notes will be issued under the same Indenture (as defined)
as the Outstanding Notes. In the event that the Exchange Offer is consummated,
any Outstanding Notes that remain outstanding after consummation of the Exchange
Offer and the Exchange Notes issued in the Exchange Offer will vote together as
a single class for purposes of determining whether holders of the requisite
percentage in outstanding principal amount of Notes have taken certain actions
or exercised certain rights under the Indenture.

      The Exchange Notes will be general, unsecured obligations of the Company,
subordinated in right of payment to all existing and any future Senior
Indebtedness (as defined) of the Company. The Exchange Notes will rank pari
passu with existing and any future senior subordinated indebtedness and senior
to any future subordinated indebtedness of the Company. See "Description of the
Exchange Notes -- Subordination of the Exchange Notes." The Indenture permits
the Company and its Restricted Subsidiaries (as defined) to incur additional
Indebtedness (as defined) under certain circumstances. See 
<PAGE>
"Use of Proceeds," "Description of Outstanding Securities and Debt Instruments"
and "Description of the Exchange Notes."

      Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Notes received in exchange for Outstanding Notes where
such Outstanding Notes were acquired by such broker-dealer as a result of market
making activities or other trading activities. The Company has agreed that,
starting on the Expiration Date (as defined) and ending on the close of business
on the forty-fifth day following the Expiration Date, it will make this
Prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."

SEE "RISK FACTORS" BEGINNING ON PAGE 18 FOR A DISCUSSION OF CERTAIN FACTORS THAT
SHOULD BE CONSIDERED IN CONNECTION WITH THE EXCHANGE OFFER.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
   
                The date of this Prospectus is October 10, 1997.
    
                                       2

      The Company is making the Exchange Offer in reliance on the position of
the staff of the Division of Corporation Finance of the Securities and Exchange
Commission (the "Commission") as set forth in certain interpretive letters
addressed to third parties in other transactions. However, the Company has not
sought its own interpretive letter and there can be no assurance that the staff
of the Division of Corporation Finance of the Commission would make a similar
determination with respect to the Exchange Offer as it has in such interpretive
letters to third parties. Based on these interpretations by the staff of the
Division of Corporation Finance, and subject to the two immediately following
sentences, the Company believes that the Exchange Notes issued pursuant to this
Exchange Offer in exchange for the Outstanding Notes may be offered for resale,
resold and otherwise transferred by a holder thereof (other than a holder who is
a broker-dealer) without further compliance with the registration and prospectus
delivery requirements of the Securities Act, provided that such Exchange Notes
are acquired in the ordinary course of such holder's business and that such
holder is not participating, and has no arrangement or understanding with any
person to participate, in a distribution (within the meaning of the Securities
Act) of such Exchange Notes. However, any holder of the Outstanding Notes who is
an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act or who intends to participate in the Exchange Offer for the
purpose of distributing Exchange Notes, or any broker-dealer who purchased
Outstanding Notes from the Company to resell pursuant to Rule 144A under the
Securities Act ("Rule 144A") or any other available exemption under the
Securities Act, (a) will not be able to rely on the interpretations of the staff
of the Division of Corporation Finance of the Commission set forth in the above
mentioned interpretive letters, (b) will not be permitted or entitled to tender
such Outstanding Notes in the Exchange Offer and (c) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale or other transfer of such Outstanding Notes unless such
sale is made pursuant to an exemption from such requirements. Each broker-dealer
that receives Exchange Notes for its own account in exchange for Outstanding
Notes, where such Outstanding Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must acknowledge
that it will deliver a prospectus in connection with any resale of such Exchange
Notes. See "Plan of Distribution." In the event that applicable interpretations
by the staff of the Division of Corporation Finance of the Commission change or
otherwise do not permit resales of the Exchange Notes without compliance with
the registration and prospectus delivery requirements of the Securities Act,
holders of Exchange Notes who transfer Exchange Notes in violation of the
prospectus delivery provisions of the Securities Act or without an exemption
from registration thereunder may incur liability thereunder.

      Each holder of Outstanding Notes who wishes to exchange Outstanding Notes
for Exchange Notes in the Exchange Offer will be required to represent that (i)
it is not an "affiliate" of the Company, (ii) any Exchange Notes to be received
by it are being acquired in the ordinary course of its business, (iii) it has no
arrangement or understanding with any person to participate in a distribution
(within the meaning of the Securities Act) of such Exchange Notes, and (iv) if
such holder is not a broker-dealer, such holder is not engaged in, and does not
intend to engage in, a distribution (within the meaning of the Securities Act)
of such Exchange Notes. Each broker-dealer that receives Exchange Notes for its
own account pursuant to the Exchange Offer must acknowledge that it acquired the
Outstanding Notes for its own account as the result of market-making activities
or other trading activities and must agree that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale of
such Exchange Notes. The Letter of Transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. Based on the
position taken by the staff of the Division of Corporation Finance of the
Commission in the interpretive letters referred to above, the Company believes
that broker-dealers who acquired Outstanding Notes for their own accounts as a
result of market-making activities or other trading activities ("Participating
Broker-Dealers") may fulfill the prospectus delivery requirements with respect
to the Exchange Notes received upon exchange of such Outstanding Notes (other
than Outstanding Notes that represent an unsold allotment from the original sale
of the Outstanding Notes) with a prospectus meeting the requirements of the
Securities Act, which may be the prospectus prepared for an exchange offer so
long as it contains a 

                                       3
<PAGE>
description of the plan of distribution with respect to the resale of such
Exchange Notes. Accordingly, this Prospectus, as it may be amended or
supplemented from time to time, may be used by a Participating Broker-Dealer
during the period referred to below in connection with resales of Exchange Notes
received in exchange for Outstanding Notes, where such Outstanding Notes were
acquired by such Participating Broker-Dealer for its own account as a result of
market-making or other trading activities. Subject to certain provisions set
forth in the Registration Agreement, the Company has agreed that this
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Participating Broker-Dealer in connection with resales of such Exchange
Notes for a period ending forty-five days after the consummation of the Exchange
Offer or, if earlier, when all such Exchange Notes have been disposed of by such
Participating Broker-Dealer. See "Plan of Distribution." Any Participating
Broker-Dealer who is an "affiliate" of the Company may not rely on such
interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale of
Exchange Notes. See "The Exchange Offer -- Resales of Exchange Notes."

      In that regard, each Participating Broker-Dealer who surrenders
Outstanding Notes pursuant to the Exchange Offer will be deemed to have agreed,
by execution of the Letter of Transmittal, that, upon receipt of notice from the
Company of the occurrence of any event or the discovery of any fact which makes
any statement contained in the Prospectus untrue in any material respect or
which causes this Prospectus to omit to state a material fact necessary in order
to make the statements contained herein, in light of the circumstances under
which they were made, not misleading or of the occurrence of certain other
events specified in the Registration Agreement, such Participating Broker-Dealer
will suspend the sale of Exchange Notes pursuant to this Prospectus until the
Company has amended or supplemented this Prospectus to correct such misstatement
or omission and has furnished copies of the amended or supplemented Prospectus
to each such Participating Broker-Dealer or the Company has give notice that the
sale of Exchange Notes may be resumed, as the case may be. If the Company gives
such notice to suspend the sale of the Exchange Notes, it shall extend the
forty-five day period referred to above during which Participating
Broker-Dealers are entitled to use this Prospectus in connection with the resale
of Exchange Notes by the number of days during the period from and including the
date of the giving of such notice to and including the date when Participating
Broker-Dealers shall have received copies of the amended or supplemented
Prospectus necessary to permit resales of the Exchange Notes or to and including
the date on which the Company has given notice that the sale of Exchange Notes
may be resumed, as the case may be.

      Prior to the Exchange Offer, there has been only a limited secondary
market and no public market for the Outstanding Notes. The Exchange Notes will
be a new issue of securities for which there is currently no market.
Accordingly, there can be no assurance as to the development or liquidity of any
market for the Exchange Notes. Although the Initial Purchaser has informed the
Company that it currently intends to make a market in the Exchange Notes, it is
not obligated to do so, and any such market making may be discontinued at any
time without notice. Accordingly, there can be no assurance as to the
development or liquidity of any market for the Exchange Notes. The Company
currently does not intend to apply for listing of the Exchange Notes on any
securities exchange or for quotation through the National Association of
Securities Dealers Automated Quotation System.

      Any Outstanding Notes not tendered and accepted in the Exchange Offer will
remain outstanding and will be entitled to all the same rights and will be
subject to the same limitations applicable thereto under the Indenture (except
for those rights that terminate upon the consummation of the Exchange Offer).
Following consummation of the Exchange Offer, the holders of Outstanding Notes
will continue to be subject to the existing restrictions upon transfer thereof
and the Company will have no further obligation to such holders (other than the
Initial Purchaser or under certain limited circumstances relating to holders who
are not eligible to participate in the Exchange Offer) to provide the
registration under the Securities Act of the Outstanding Notes held by them. If
Outstanding Notes are tendered and accepted in the 

                                       4
<PAGE>
Exchange Offer, the market for untendered Outstanding Notes is likely to
diminish; accordingly, holders who do not tender their Outstanding Notes may
encounter difficulties in selling such notes following the Exchange Offer. See
"Risk Factors -- Consequences of a Failure to Exchange Outstanding Notes."

      THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OUTSTANDING NOTES ARE URGED TO READ THIS PROSPECTUS AND
THE RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO TENDER
THEIR OUTSTANDING NOTES PURSUANT TO THE EXCHANGE OFFER.
   
      Outstanding Notes may be tendered for exchange on or prior to 5:00 p.m.,
New York City time, on November 10, 1997 ("Expiration Date"), unless the
Exchange Offer is extended by the Company (in which case the term "Expiration
Date" shall mean the latest date and time to which the Exchange Offer is
extended). Tenders of Outstanding Notes may be withdrawn at any time on or prior
to the Expiration Date. The Exchange Offer is not conditioned upon any minimum
principal amount of Outstanding Notes being tendered for exchange. However, the
Exchange Offer is subject to certain events and conditions and to the terms and
provisions of the Registration Agreement. See "The Exchange Offer -- Conditions
to the Exchange Offer." Outstanding Notes may be tendered in whole or in part in
a principal amount of $1,000 and integral multiples thereof. The Company has
agreed to pay all expenses of the Exchange Offer. Each Exchange Note will bear
interest from the most recent date to which interest has been paid or duly
provided for on the Outstanding Note surrendered in exchange for such Exchange
Note or, if no such interest has been paid or duly provided for on such
Outstanding Note, from July 31, 1997. Holders of the Outstanding Notes whose
Outstanding Notes are accepted for exchange will not receive accrued interest on
such Outstanding Notes for any period from and after the last interest payment
date to which interest has been paid or duly provided for on such Outstanding
Notes prior to the original issue date of the Exchange Notes or, if no such
interest has been paid or duly provided for, will not receive any accrued
interest on such Outstanding Notes, and will be deemed to have waived the right
to receive any interest on such Outstanding Notes accrued from and after such
interest payment date or, if no such interest has been paid or duly provided
for, from and after July 31, 1997. This Prospectus, together with the Letter of
Transmittal, is being sent to all registered holders of the Outstanding Notes as
of October 9, 1997.
    
      The Company will not receive any cash proceeds from the issuance of the
Exchange Notes offered hereby. See "Use of Proceeds." No dealer-manager is being
used in connection with this Exchange Offer. See "Plan of Distribution."
Solicitation of tenders of Outstanding Notes may be made in person or by mail,
telephone or telegram, by directors, officers and regular employees of the
Company. Such persons will receive no additional compensation for any
solicitation activities. The Company may employ third-party agents to solicit
tenders of Outstanding Notes, for which services such agents would be paid their
usual and customary fee.

OTHER THAN THE SECURITIES TO WHICH IT RELATES OR AN OFFER TO ANY PERSON IN ANY

      The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and the Consolidated
Financial Statements, and the notes thereto appearing elsewhere in this
Prospectus. Prospective purchasers should carefully consider the information set
forth in "Risk Factors" in evaluating the Exchange Offer. Unless the context
otherwise requires, all references in this Prospectus to "Callon" or the
"Company" are to Callon Petroleum Company and its subsidiaries. Certain terms
relating to the oil and gas industry are defined in "Glossary".

                                   THE COMPANY

      Callon Petroleum Company and its predecessors have been engaged in the
acquisition, development, exploration and production of oil and gas since 1950.
The Company's properties are geographically concentrated in Louisiana, Alabama
and offshore Gulf of Mexico. Callon also manages properties for certain
institutional investors. Callon was formed in 1994 through the consolidation of
a publicly traded limited partnership, a joint venture with a consortium of
European entities and an independent energy company owned by certain members of
current management. As of December 31, 1996, the Company had estimated net
proved reserves of 73.3 Bcfe with a PV-10 Value of $160.2 million, representing
increases of 26% and 151% respectively, from December 31, 1995.

      The Company's objective is to enhance stockholder value through sustained
growth in its reserve base, production levels and resulting cash flows from
operations. Over the past two and one-half years, the Company has increasingly
supplemented the acquisition of producing properties with the acquisition of
acreage with development and exploratory drilling opportunities to further
increase potential recoverable reserves. Since 1995, the Company has generated
47 prospects on 217,000 gross acres. In evaluating drilling opportunities,
Callon performs extensive geological and geophysical studies using computer
aided exploration techniques ("CAEX"), including, where appropriate, the
acquisition of 3-D seismic or high-resolution 2-D seismic data to facilitate
these efforts.

      EXPLORATION AND DEVELOPMENT OPERATIONS. The Company's exploratory and
development operations are concentrated in three areas in the Gulf of Mexico:
(i) the state waters of Alabama and the federal outer continental shelf ("OCS")
in the Gulf of Mexico where the Company explores for shallow gas deposits
("Shallow Gas focus area"); (ii) the Breton Sound area located primarily in the
shallow state waters of Louisiana, where the Company explores for hydrocarbon
deposits at total well depths of between 8,000 to 14,000 feet ("Breton Sound
focus area"); and (iii) other regions of the OCS, where the Company explores for
hydrocarbon deposits at total well depths of between 9,000 and 18,000 feet
("Deep OCS focus area"). Wells drilled in the Shallow Gas focus area are
characterized by relatively low exploration and development costs, high initial
production rates and short reserve lives. Wells drilled in the Breton Sound
focus area and Deep OCS focus area are more expensive to drill and complete and
have greater risks, but seek larger oil and gas deposits with longer reserve
lives.

      In 1995 and 1996, the Company acquired an extensive infrastructure of
production platforms, gathering systems and pipelines in its Shallow Gas focus
area and, during 1996, completed four proprietary high resolution 2-D seismic
surveys over an eight block area. Based on these surveys, in October and
November of 1996, the Company drilled two gross (1.52 net) successful
development wells and one gross (1.0 net) successful exploratory well in this
area. These wells were placed on production by the end of December 1996 and,
coupled with the replacement of compression equipment at the related production
facilities, the Company's average daily oil and gas production increased to 43.5
MMcfe/d during the first half of 1997, representing a 67% increase over 1996
average daily production rates. During the first six months of 1997, the Company
drilled one additional successful development well (1.0 net), one unsuccessful
development well for a net cost of $1.2 million, and performed one major
recompletion in its Shallow Gas focus area. Production from the new well
commenced in July 1997 and the recompletion is currently producing 6.3 MMcf/d
(3.6 MMcf/d net to the Company). The Company's capital budget for the last six
months of 1997 includes the drilling of five gross (2.7 net) exploratory wells
in its Shallow Gas focus area, for an aggregate net cost to drill and complete
of approximately $10.0 million.

                                       7
<PAGE>
      In its Breton Sound focus area, the Company owns and operates several old
prolific fields. In November 1996, the Company completed a 36 square-mile 3-D
seismic survey on its Main Pass 35 Field and adjoining acreage which resulted in
the identification of one development and seven exploratory drilling prospects.
Based upon this new data, the Company acquired an additional 5,170 gross acres,
which increased its holdings in the Breton Sound focus area to almost 10,000
gross acres. In July 1997, the Company entered into a joint venture agreement
with Burlington Resources Oil & Gas Company to drill these prospects. The
Company will operate these prospects and has retained an approximate 42.4%
working interest. In addition, the Company acquired a 100% working interest in a
development prospect on an adjacent block. The Company's capital budget for the
last six months of 1997 in the Breton Sound focus area includes the drilling of
two gross (1.45 net) development and one gross (0.45 net) exploratory wells for
an aggregate net cost to Callon to drill and complete of approximately $8.2
million.

      In 1996, the Company joined with Murphy Exploration and Production, Inc.
("Murphy") to acquire 18 federal blocks in the Deep OCS focus area and in 1997
joined with Murphy and another oil company to acquire an additional 13 blocks,
four of which are located in the Shallow Gas focus area. The Company owns a 25%
working interest in 23 of these blocks and a 20% working interest in the
remaining eight. Murphy operates these properties. To date Callon has
participated with Murphy in the drilling of four gross (1.0 net) unsuccessful
exploratory wells at a total cost of $6.1 million, net to the Company. The
Company's capital budget for the last six months of 1997 includes the drilling
of one gross (0.2 net) Deep OCS focus area exploratory prospect at a net cost to
Callon to drill and complete of approximately $2.9 million.

      In total, the Company's current capital budget includes the drilling of
two gross (1.5 net) development wells and seven gross (3.3 net) exploratory
wells during the last six months of 1997 at an estimated net cost to the Company
to drill and complete of approximately $21.2 million. These drilling operations
will be financed from cash flows from operations, the net proceeds of the
offering of the Outstanding Notes and borrowings under the Company's credit
facility with a commercial bank ("Credit Facility"). See "Use of Proceeds."

      PRODUCING PROPERTY ACQUISITIONS. Over the past eight years, the Company
has increased its reserves through the acquisition of producing properties that
are geologically complex, have (or are analogous to fields with) an established
production history from stacked pay zones and are candidates for additional
exploitation. The Company focuses on reducing operating costs and implementing
production enhancements through the application of technologically advanced
production and recompletion techniques. Between 1989 and December 31, 1996,
Callon acquired producing properties in 21 negotiated transactions, on behalf of
itself and, in certain cases, its primary institutional investor, for an
aggregate net purchase price of approximately $206 million and, during that
period, the Company had an average Reserve Replacement Cost of $0.84 per Mcfe.

      ELF ACQUISITION. In June 1997, the Company purchased from Elf Exploration,
Inc. ("Elf Exploration") an 18.8% working interest in the Mobile Area Block 864
Unit for approximately $11.8 million. The transaction also included Elf
Exploration's 17.5% working interest in Mobile Area Blocks 863 and 907 and a 35%
working interest in Mobile Area Block 908. The Mobile Area Block 864 Unit,
operated by Chevron, is located in the Company's Shallow Gas focus area about 12
miles south-southwest of the Company's North Dauphin Island Field and is
currently producing 26 MMcf/d through the unit's facilities from sub-sea depths
of 2,400 feet and 2,700 feet. The Company believes exploratory drilling
opportunities exist on the three blocks. See the Company's MAB 864 Acquisition
Financial Statements for further information regarding the acquisition from Elf
Exploration.

      TECHNOLOGICAL EXPERTISE. Through its acquisition program, the Company has
assembled an operational and technical database in certain geographical areas at
a low cost to the Company. The relationship with its institutional investors has
allowed the Company to pursue larger acquisitions, while the cost sharing
arrangements and ongoing management fees have enabled the Company to enhance the
rate of return on its properties and to maintain a larger, more experienced team
of technical and operating personnel than otherwise would be feasible for a
company of its size.

                                       Each broker-dealer that receives Exchange
                                       Notes for its own account in exchange for
                                       Outstanding Notes, where such Outstanding
                                       Notes were acquired by such broker-dealer
                                       as a result of market making activities
                                       or other trading activities, may
                                       participate in the Exchange Offer but may
                                       be deemed an "underwriter" under the
                                       Securities Act and, therefore, must
                                       acknowledge in the Letter of Transmittal
                                       that it will deliver a prospectus in
                                       connection with any resale of such
                                       Exchange Notes. The Company has
                                       undertaken, for a period of forty-five
                                       days from the consummation of the
                                       Exchange Offer, to maintain the
                                       effectiveness of this Prospectus for use
                                       in satisfaction of such persons'
                                       obligations to deliver a prospectus. The
                                       Letter of Transmittal states that by so
                                       acknowledging and by delivering a
                                       prospectus, a broker-dealer will not be
                                       deemed to admit that it is an
                                       "underwriter" within the meaning of the
                                       Securities Act. See "The Exchange Offer
                                       -- Resales of Exchange Notes."

SPECIAL PROCEDURES FOR 
BENEFICIAL OWNERS...................   Any beneficial owner whose Outstanding
                                       Notes are registered in the name of a
                                       broker, dealer, commercial bank, trust
                                       company or other nominee and who wishes
                                       to tender such Outstanding Notes in the

                                       beneficial owner's behalf. If such
                                       beneficial owner wishes to tender on its
                                       own behalf, such owner must, prior to

                                       indebtedness if the ratio of the
                                       Company's consolidated Indebtedness for
                                       Money Borrowed (as defined) to
                                       Consolidated EBITDA (as defined) would
                                       exceed 10.0:1 or if the ratio of
                                       Consolidated EBITDA to Consolidated
                                       Interest Expense (as defined) would be
                                       less than 1.1:1. The Indenture will also
                                       prohibit restrictions on the payments of

(1)   The Company succeeded to the business and properties of Callon Petroleum
      Operating Company ("Callon Petroleum Operating"), Callon Consolidated
      Partners, L.P. ("CCP") and CN Resources ("CN") on September 16, 1994 (the
      "Consolidation"). Historical information about the Company prior to
      September 16, 1994 includes the financial and operating information of the
      predecessors of the Company, other than the interest in CN not owned by
      Callon Petroleum Operating, combined as entities under common control in a
      manner similar to a pooling of interests. See "The Company."

(2)   EBITDA is earnings before interest, taxes, depreciation, depletion and
      amortization. EBITDA is presented because it is a widely accepted
      financial indication of a company's ability to service and incur debt.
      EBITDA should not be considered as an alternative to earnings (loss) as an
      indicator of the Company's operating performance or to cash flow as a
      measure of liquidity.

(3)   For purpose of computing this ratio, "earnings" represent income (loss)
      before income taxes and extraordinary item plus fixed charges. "Fixed
      charges" consist of interest expense on all indebtedness and that portion
      of rental expense considered to be representative of the interest factor
      therein. As a result of the loss incurred for the year ended December 31,
      1994 earnings did not cover fixed charges by $313,000.

(1)   The Company succeeded to the business and properties of its predecessor
      entities on September 16, 1994 pursuant to the Consolidation. Historical
      data about the Company prior to September 16, 1994 includes the operating
      data of the Company's predecessors, other than the interest in CN not
      owned by Callon Petroleum Operating, combined as entities under common
      control, in a manner similar to a pooling of interests. See "The Company."

(2)   Future net cash flows attributable to the Company's estimated proved
      reserves and the present value of such cash flows were based on an average
      gas price of $3.88 per Mcf and an average oil price of $23.58 per Bbl at
      December 31, 1996. The average price received for production in 1996 was
      $2.63 per Mcf for gas and $20.55 per Bbl for oil, without the effects of
      hedging.

      THIS PROSPECTUS INCLUDES "FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING
OF SECTION 27A OF THE SECURITIES ACT AND SECTION 21E OF THE EXCHANGE ACT. ALL
STATEMENTS OTHER THAN STATEMENTS OF HISTORICAL FACTS INCLUDED IN THIS
PROSPECTUS, INCLUDING WITHOUT LIMITATION, STATEMENTS UNDER "PROSPECTUS SUMMARY",
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS" AND "BUSINESS AND PROPERTIES" REGARDING THE COMPANY'S FINANCIAL
POSITION, ESTIMATED RESERVE QUANTITIES AND NET PRESENT VALUES OF RESERVES,
BUSINESS STRATEGY, PLANS AND OBJECTIVES OF MANAGEMENT OF THE COMPANY FOR FUTURE
OPERATIONS AND COVENANT COMPLIANCE, ARE FORWARD-LOOKING STATEMENTS. ALTHOUGH THE
COMPANY BELIEVES THAT THE ASSUMPTIONS UPON WHICH SUCH FORWARD-LOOKING STATEMENTS
ARE BASED ARE REASONABLE, IT CAN GIVE NO ASSURANCES THAT SUCH ASSUMPTIONS 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 AND ELSEWHERE IN THIS PROSPECTUS. 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. PROSPECTIVE
PURCHASERS OF THE NOTES OFFERED HEREBY SHOULD CAREFULLY CONSIDER, TOGETHER WITH
OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING FACTORS THAT AFFECT THE
COMPANY.

SIGNIFICANT LEVERAGE AND DEBT SERVICE

      As of June 30, 1997, as adjusted to give effect to the sale of the Notes
and the application of the net proceeds therefrom, the Company's total long-term
debt would have been approximately $60.3 million. See "Capitalization" and "Use
of Proceeds." The Company's level of indebtedness will have several important
effects on its future operations, including (i) a substantial portion of the
Company's cash flow from operations must be dedicated to the payment of interest
on its indebtedness and will not be available for other purposes, (ii) covenants
contained in the Company's debt obligations will require the Company to meet
certain financial tests, and other restrictions will limit its ability to borrow
additional funds or to dispose of assets and may affect the Company's
flexibility in planning for, and reacting to, changes in its business, including
possible acquisition activities and (iii) the Company's ability to obtain
financing in the future for working capital, capital expenditures, acquisitions,
general corporate purposes or other purposes may be impaired. The Company's
ability to meet its debt service obligations and to reduce its total
indebtedness will be dependent upon the Company's future performance, which will
be subject to general economic conditions and to financial, business and other
factors affecting the operations of the Company, many of which are beyond its
control.

SUBORDINATION

      The Outstanding Notes are and the Exchange Notes will be subordinated in
right of payment to all existing and future Senior Indebtedness of the Company
and will rank PARI PASSU with the Company's existing and future senior
subordinated indebtedness, including the Existing Notes. In the event of
bankruptcy, liquidation or reorganization of the Company, the assets of the
Company will be available to pay obligations on the Notes only after all Senior
Indebtedness has been paid in full, and there may not be sufficient assets
remaining to pay amounts due on any or all of the Notes outstanding. The Notes
are also structurally subordinated to the obligations of the Company's
subsidiaries. As of June 30, 1997, on a pro forma basis giving effect to the
issuance of the Notes, the Company had outstanding $100,000 of Senior
Indebtedness, $36.0 million of Notes and $24.2 million of Existing Notes, and
the total amount of liabilities of the Company's subsidiaries as of June 30,
1997 was $13.9 million, excluding guarantees of Senior Indebtedness. The
Existing Notes rank PARI PASSU with the Outstanding Notes and will rank PARI
PASSU with the Exchange Notes. Additional Senior Indebtedness may be incurred by
the Company from time to time, subject to certain restrictions, and the
Company's subsidiaries may incur obligations which 

                                       18
<PAGE>
are structurally senior to the Notes. See "Description of the Exchange Notes --
Subordination of the Exchange Notes."

CONSEQUENCES OF A FAILURE TO EXCHANGE OUTSTANDING NOTES

      The Outstanding Notes have not been registered under the Securities Act or
any state securities laws and therefore may not be offered, sold or otherwise
transferred except in compliance with the registration requirements of the
Securities Act and any other applicable securities laws, or pursuant to an
exemption therefrom or in a transaction not subject thereto, and in each case in
compliance with certain other conditions and restrictions, including the
Company's and the Trustee's right in certain cases to require the delivery of
opinions of counsel, certifications and other information prior to any such
transfer. Outstanding Notes that remain outstanding after the consummation of
the Exchange Offer will continue to bear a legend reflecting such restrictions
on transfer. In addition, upon consummation of the Exchange Offer, holders of
Outstanding Notes that remain outstanding will not be entitled to any rights to
have such Outstanding Notes registered under the Securities Act or to any
similar rights under the Registration Agreement (subject to certain limited
exceptions). The Company currently intends to register under the Securities Act
Outstanding Notes that remain outstanding after consummation of the Exchange
Offer only if such Outstanding Notes are held by the Initial Purchaser and
persons ineligible to participate in the Exchange Offer. If Outstanding Notes
are tendered and accepted in the Exchange Offer, the market for untendered
Outstanding Notes is likely to diminish; accordingly, holders who do not tender
their Outstanding Notes may encounter difficulties in selling such notes
following the Exchange Offer.

      The Exchange Notes and any Outstanding Notes that remain outstanding after
consummation of the Exchange Offer will constitute a single series of debt
securities under the Indenture and, accordingly, will vote together as a single
class for purposes of determining whether holders of the requisite percentage in
outstanding principal amount thereof have taken certain actions or exercised
certain rights under the Indenture. See "Description of the Exchange Notes."

      The Indenture provides that if (i) an exchange offer registration
statement or resale shelf registration statement is not filed by October 1, 1997
or (ii) an exchange offer registration statement is not declared effective by
November 15, 1997, Special Interest will accrue and be payable quarterly until
such time as a registration statement is filed or becomes effective, as the case
may be. In addition, if (i) an exchange offer is not consummated or a resale
shelf registration statement is not declared effective by December 31, 1997 or
(ii) either the exchange offer registration statement or the resale shelf
registration statement has been declared effective and such registration
statement ceases to be effective or usable (subject to certain exceptions),
Special Interest will accrue and be payable quarterly until such time as an
exchange offer is consummated or a resale shelf registration statement is
declared effective, as the case may be. Following consummation of the Exchange
Offer neither the Outstanding Notes nor the Exchange Notes will be entitled to
any increase in the interest rate thereon. See "Description of the Outstanding
Notes" and "Description of the Exchange Notes."

LACK OF PUBLIC MARKET

      The Outstanding Notes were issued to, and the Company believes are
currently owned by, a relatively small number of beneficial owners. The
Outstanding Notes have not been registered under the Securities Act and will be
subject to restrictions on transferability to the extent that they are not
exchanged for Exchange Notes. See "-- Consequences of a Failure to Exchange
Outstanding Notes."

      Although the Exchange Notes will generally be permitted to be resold or
otherwise transferred by the holders (who are not affiliates of the Company)
without compliance with the registration and prospectus delivery requirements
under the Securities Act, they will constitute a new issue of securities

                                       19
<PAGE>
with no established trading market. See "The Exchange Offer -- Resales of
Exchange Notes." The Company has been advised by the Initial Purchaser that the
Initial Purchaser presently intends to make a market in the Exchange Notes.
However, the Initial Purchaser is not obligated to do so and any market making
activity with respect to the Exchange Notes may be discontinued at any time
without notice. In addition, such market making activity will be subject to the
limits imposed by the Securities Act and the Exchange Act and may be limited
during the Exchange Offer. If the Exchange Notes are traded after their initial
issuance, they may trade at a discount from their initial offering price,
depending upon prevailing interest rates, the market for similar securities and
other factors including general economic conditions and the financial condition
of the Company. The Company does not intend to apply for a listing or quotation
of the Exchange Notes on any securities exchange or stock market. Accordingly,
there can be no assurance as to the development or liquidity of any market for
the Exchange Notes.

      The liquidity of, and trading market for, the Notes also may be adversely
affected by general declines in the market for similar securities. Such a
decline may adversely affect such liquidity and trading markets independent of
the financial performance of, and prospects for, the Company.

      Notwithstanding the registration of the Exchange Notes in the Exchange
Offer, holders who are "affiliates" (as defined under Rule 405 of the Securities
Act) of the Company may publicly offer for sale or resell the Exchange Notes
only in compliance with the provisions of Rule 144 under the Securities Act. See
"The Exchange Offer -- Resales of Exchange Notes."

      Each broker-dealer that receives Exchange Notes for its own account in
exchange for Outstanding Notes, where such Outstanding Notes were acquired by
such broker-dealer as a result of market making activities or other trading
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. See "The Exchange Offer -- Resales of
Exchange Notes."

EXCHANGE OFFER PROCEDURES

      Issuance of the Exchange Notes in exchange for the Outstanding Notes
pursuant to the Exchange Offer will be made only after timely receipt by the
Company of such Outstanding Notes, a properly completed and duly executed Letter
of Transmittal and all other required documents. Therefore, holders of the
Outstanding Notes desiring to tender such Outstanding Notes in exchange for
Exchange Notes should allow sufficient time to ensure timely delivery. The
Company is under no duty to give notification of defects or irregularities with
respect to tenders of Outstanding Notes for exchange.

VOLATILITY OF OIL AND GAS PRICES; MARKETABILITY OF PRODUCTION

      The Company's revenues, profitability and future growth and the carrying
value of its oil and gas properties are substantially dependent on prevailing
prices of oil and gas. The Company's ability to maintain or increase its
borrowing capacity and to obtain additional capital on attractive terms is also
substantially dependent upon 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 regulation, 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.

                                       20
<PAGE>
      The Company's estimated proved reserves, future net cash flows
attributable to the Company's estimated net proved reserves and the present
value of such cash flows were based on an average gas price of $3.88 per Mcf and
an average oil price of $23.58 per Bbl at December 31, 1996. The average price
received for production in 1996 was $2.63 per Mcf for gas and $20.55 per Bbl for
oil, without the effects of hedging.

      Volatile oil and gas prices make it difficult to estimate the value of
producing properties for acquisition and often cause disruption in the market
for oil and gas producing properties, as buyers and sellers have difficulty
agreeing on such value. Price volatility also makes it difficult to budget for
and project the return on acquisitions and development and exploitation
projects.

      In addition, the marketability of the Company's production depends upon
the availability and capacity of gas gathering systems, pipelines and processing
facilities. Federal and state regulation of oil and gas production and
transportation, general economic conditions and changes in supply and demand all
could adversely affect the Company's ability to produce and market its oil and
natural gas. If market factors were to change dramatically, the financial impact
on the Company could be substantial. The availability of markets and the
volatility of product prices are beyond the control of the Company and represent
a significant risk.

RISKS OF EXPLORATION AND DEVELOPMENT

      The major focus of the Company's operations over the next two years is
expected to be the exploration for and development of oil and gas properties,
primarily in federal and state waters in the Gulf of Mexico. Exploration and
drilling activities are generally considered to be of a higher risk than
acquisitions of producing oil and gas properties. Additionally, the Company's
wells in its Deep OCS focus area seek to discover deposits of gas at deep
formations, and have more risk than wells seeking to develop hydrocarbons from
shallow formations. No assurances can be made that the Company will discover oil
and gas in commercial quantities in its exploration and development operations.
Expenditure of a material amount of funds in exploration for oil and gas without
discovery of commercial quantities of reserves will have a material adverse
effect upon the Company.

OPERATING HAZARDS, OFFSHORE OPERATIONS AND UNINSURED RISKS

      Callon's operations are subject to risks inherent in the oil and gas
industry, such as blowouts, cratering, explosions, uncontrollable flows of oil,
gas or well fluids, fires, pollution and other environmental risks. These risks
could result in substantial losses to the Company due to injury and loss of
life, severe damage to and destruction of property and equipment, pollution and
other environmental damage and suspension of operations. Moreover, a substantial
portion of the Company's operations are offshore and therefore are subject to a
variety of operating risks peculiar to the marine environment, such as
hurricanes or other adverse weather conditions, to more extensive governmental
regulation, including regulations that may, in certain circumstances, impose
strict liability for pollution damage, and to interruption or termination of
operations by governmental authorities based on environmental or other
considerations.

      The Company maintains insurance of various types to cover its operations,
including maritime, employer's liability and comprehensive general liability.
Amounts in excess of base coverages are provided by primary and excess umbrella
liability policies with maximum limits of $50 million. In addition, the Company
maintains operator's extra expense coverage, which provides coverage for the
control of wells drilled and/or producing and redrilling expenses and pollution
coverage for wells out of control.

                                       21
<PAGE>
      No assurances can be given that Callon will be able to maintain adequate
insurance in the future at rates the Company considers reasonable. The
occurrence of a significant event not fully insured or indemnified against could
materially and adversely affect the Company's financial condition and results of
operations.

ESTIMATES OF OIL AND GAS RESERVES

      This Prospectus contains estimates of oil and gas reserves, and the future
net cash flows attributable to those reserves, prepared by Huddleston & Co.,
Inc., independent petroleum and geological engineers (the "Reserve Engineers")
and by the Company's reserve engineers. There are numerous uncertainties
inherent in estimating quantities of proved reserves and cash flows attributable
to such reserves, including factors beyond the control of the Company and the
Reserve Engineers. Reserve engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
manner. The accuracy of an estimate of quantities of reserves, or of cash flows
attributable to such reserves, is a function of the available data, assumptions
regarding future oil and gas prices and expenditures for future development and
exploitation activities, and of engineering and geological interpretation and
judgment. Additionally, reserves and future cash flows may be subject to
material downward or upward revisions, based upon production history,
development and exploitation activities and prices of oil and gas. Actual future
production, revenue, taxes, development expenditures, operating expenses,
quantities of recoverable reserves and the value of cash flows from such
reserves may vary significantly from the assumptions and estimates set forth
herein. In addition, reserve engineers may make different estimates of reserves
and cash flows based on the same available data. In calculating reserves on a
Mcfe basis, oil was converted to gas equivalent at the ratio of six Mcf of gas
to one Bbl of oil. While this ratio approximates the energy equivalency of gas
to oil on a Btu basis, it may not represent the relative prices received by the
Company on the sale of its oil and gas production.

      The estimated quantities of proved reserves and the discounted present
value of future net cash flows attributable to estimated proved reserves set
forth in this Prospectus were prepared by the Reserve Engineers in accordance
with the rules of the Commission, and are not intended to represent the fair
market value of such reserves.

ABILITY TO REPLACE RESERVES

      The Company's future success depends upon its ability to find, develop and
acquire additional oil and gas reserves that are economically recoverable. As is
generally the case in the Gulf Coast region, many of the Company's producing
properties are characterized by a high initial production rate, followed by a
steep decline in production. As a result, the Company must locate and develop or
acquire new oil and gas reserves to replace those being depleted by production.
Without successful exploration or acquisition activities, the Company's reserves
and revenues will decline rapidly. No assurances can be given that the Company
will be able to find and develop or acquire additional reserves at an acceptable
cost.

      The exploration for oil and gas requires the expenditure of substantial
amounts of capital, and there can be no assurances that commercial quantities of
oil or gas will be discovered as a result of such activities. The Company's
current capital budget includes drilling two gross (1.5 net) development wells
and seven gross (3.3 net) exploratory wells during the last six months of 1997.
The estimated cost, net to the Company, to drill and complete these wells is
approximately $21.2 million with dry hole costs of approximately $10.3 million.
The drilling of several unsuccessful wells in this area could have a material
adverse effect on the Company and its ability to repay the Notes. In addition,
the successful acquisition of producing properties requires an assessment of
recoverable reserves, future oil and gas prices and operating costs, potential
environmental and other liabilities and other factors. Such assessments are
necessarily inexact and their accuracy inherently uncertain. In addition, no
assurances can be given that 

                                       22
<PAGE>
the Company's exploitation and development activities will result in any
increases in reserves. The Company's operations may be curtailed, delayed or
canceled as a result of lack of adequate capital and other factors, such as
title problems, weather, compliance with governmental regulations or price
controls, mechanical difficulties or shortages or delays in the delivery of
equipment. In addition, the costs of exploration and development may materially
exceed initial estimates.

SUBSTANTIAL CAPITAL REQUIREMENTS

      The Company makes, and will continue to make, substantial capital
expenditures for the exploitation, exploration, acquisition and production of
oil and gas reserves. Historically, the Company has financed these expenditures
primarily with cash generated by operations, proceeds from bank borrowings and
issuance of debt and equity securities. The Company's total capital expenditure
budget for the last half of 1997 is approximately $25 million and for 1998 will
range from approximately $49 million to $74 million depending on the success of
the Company's drilling activities. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Capital Expenditures." The
Company makes unsolicited offers for the acquisition of oil and gas properties
in the normal course of business. In the event that any such offers are
accepted, the amount or composition of the Company's capital expenditure budget
could be revised significantly.

      The Company believes that it will have sufficient cash provided by
operating activities, the proceeds from the offering of the Outstanding Notes
and borrowings under its Credit Facility to fund such planned capital
expenditures. If revenues or the Company's borrowing base decrease as a result
of lower oil and gas prices, operating difficulties or declines in reserves, the
Company may have limited ability to expend the capital necessary to undertake or
complete future drilling programs. There can be no assurance that additional
debt or equity financing or cash generated by operations will be available to
meet these requirements. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."

HEDGING OF PRODUCTION

      Part of the Company's business strategy is to reduce its exposure to the
volatility of oil and gas prices by hedging a portion of its production. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." In a typical hedge
transaction, the Company will have the right to receive from the counterparty to
the hedge, the excess of the fixed price specified in the hedge over a floating
price based on a market index, multiplied by the quantity hedged. If the
floating price exceeds the fixed price, the Company is required to pay the
counterparty this difference multiplied by the quantity hedged. The Company is
required to pay the difference between the floating price and the fixed price
(when the floating price exceeds the fixed price) regardless of whether the
Company has sufficient production to cover the quantities specified in the
hedge. Significant reductions in production at times when the floating price
exceeds the fixed price could require the Company to make payments under the
hedge agreements even though such payments are not offset by sales of
production. Hedging will also prevent the Company from receiving the full
advantage of increases in oil or gas prices above the fixed amount specified in
the hedge. Approximately 27% of the Company's estimated oil production for the
last six months of 1997 is hedged at a New York Mercantile Exchange ("NYMEX")
floor price of $18.00 per Bbl and a ceiling price of $24.00 per Bbl (NYMEX). In
addition, from July 1997 through March 1998, the Company has hedged 30% of its
estimated natural gas equivalent production at an average floor price of $2.00
per MMBtu (NYMEX) and an average ceiling price of $2.66 per MMBtu (NYMEX).

                                       23
<PAGE>
COMPETITION

      The Company operates in the highly competitive areas of oil and gas
exploration, development and production. The availability of funds and
information relating to a property, the standards established by the Company for
the minimum projected return on investment, the availability of alternate fuel
sources and the intermediate transportation of gas are factors which affect the
Company's ability to compete in the marketplace. The Company's competitors
include major integrated oil companies, substantial independent energy
companies, affiliates of major interstate and intrastate pipelines and national
and local gas gatherers, many of which possess greater financial and other
resources than the Company. See "Business and Properties -- Competition,
Markets and Regulation."

ENVIRONMENTAL AND OTHER REGULATIONS

      The Company's operations are subject to numerous laws and regulations
governing the discharge of materials into the environment or otherwise relating
to environmental protection. These laws and regulations may require the
acquisition of a permit before drilling commences, restrict the types,
quantities and concentration of various substances that can be released into the
environment in connection with drilling and production activities, limit or
prohibit drilling activities on certain lands lying within wilderness, wetlands
and other protected areas, require remedial measures to mitigate pollution from
former operations such as plugging abandoned wells, and impose substantial
liabilities for pollution resulting from the Company's operations. Moreover, the
recent trend toward stricter standards in environmental legislation and
regulation is likely to continue. If such stricter legislation were to be
enacted or regulations adopted, it could have a significant impact on the
operating costs of the Company, as well as the oil and gas industry in general.
Management believes that the Company is in substantial compliance with current
applicable environmental laws and regulations and that continued compliance with
existing requirements will not have a material adverse impact on the Company.

      The Company's operations could result in liability for personal injuries,
property damage, oil spills, discharge of hazardous materials, remediation and
clean-up costs and other environmental damages. Moreover, the Company could be
liable for environmental damages caused by previous property owners. As a
result, substantial liabilities to third parties or governmental entities may be
incurred, the payment of which could have a material adverse effect on the
Company's financial condition and results of operations. The Company maintains
insurance coverage for its operations, including limited coverage for sudden
environmental damages, but does not believe that insurance coverage for
environmental damages that occur over time is available at a reasonable cost.
Moreover, the Company does not believe that insurance coverage for the full
potential liability that could be caused by sudden environmental damages is
available at a reasonable cost. Accordingly, the Company may be subject to
liability or may lose the privilege to continue exploration or production
activities upon substantial portions of its properties in the event of certain
environmental damages. See "Business and Properties -- Environmental
Regulations."

CONTROL OF THE COMPANY, STOCKHOLDERS' AGREEMENT

      John S. Callon, Fred L. Callon and members of their families
(collectively, the "Callon Family") and NOCO Enterprises, L.P., a limited
partnership owned by a consortium of European institutional investors ("NOCO"),
who collectively and beneficially own over 60% of the outstanding Common Stock
have entered into a stockholders' agreement (the "Stockholders' Agreement")
pursuant to which members of the Callon Family and NOCO agree (i) to vote for
two directors nominated by each party; (ii) not to support certain changes in
control without the consent of the other party; and (iii) not to sell Common
Stock without first offering it to the other party, except in limited
circumstances. As a result of the Stockholders' Agreement, it is expected that
the members of the Callon Family and NOCO will be able to control the election
of at least four directors of the Company. NOCO has informed the Company that it
intends to transfer 1,839,386 of the Common Shares owned by it to Fred. Olsen
Energy AS ("FOE").

                                       24
<PAGE>
Upon such transfer, the Common Shares owned by FOE will continue to be subject
to the Stockholders' Agreement. See "Principal Stockholders -- Stockholders'
Agreement."

                                   THE COMPANY

      The Company was formed under Delaware law in 1994 to succeed to the
business and properties of Callon Petroleum Operating, an independent energy
company owned by members of the Callon Family, Callon Consolidated Partners,
L.P., a publicly traded limited partnership ("CCP"), and CN Resources, a joint
venture engaged in the oil and gas business ("CN").

      The predecessors of Callon Petroleum Operating were formed in 1950 by John
S. Callon. Since that time and until September 16, 1994, Callon Petroleum
Operating or its predecessors were actively engaged in the oil and gas business.
CCP was a publicly traded limited partnership formed in 1987 by the
consolidation of oil and gas limited partnerships formed by Callon Petroleum
Operating. Callon Petroleum Operating was the sole general partner of CCP. CN
was a general partnership formed in April 1992 of which Callon Petroleum
Operating and NOCO were the only partners.

      Effective September 16, 1994, pursuant to the Consolidation, CCP was
merged into the Company and the Company acquired all of the capital stock of
Callon Petroleum Operating, as well as the partnership interest in CN formerly
owned by NOCO ("NOCO Interest"). As a result, the Company has acquired the
properties and liabilities of CCP, Callon Petroleum Operating and CN. Because
all of the parties to the Consolidation (other than CN) were under common
control, the financial statements and operating data of the Company include the
financial statements and operating data of CCP and Callon Petroleum Operating,
including Callon Petroleum Operating's ownership interest in CN, which were
combined in a manner similar to a pooling of interests. The acquisition of the
NOCO Interest was recorded as a purchase effective as of the date of the
Consolidation (September 16, 1994). Amounts related to the Company's acquisition
of the NOCO Interest, therefore, are included from the date of the purchase for
the periods presented in the Consolidated Financial Statements.

      The Company's principal executive office is located at 200 North Canal
Street, Natchez, Mississippi 39120, and its telephone number is (601) 442-1601.

                               THE EXCHANGE OFFER

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

      In connection with the sale of the Outstanding Notes, the Company entered
into the Registration Agreement with the Initial Purchaser, pursuant to which
the Company agreed to file and to use its best efforts to cause to become
effective with the Commission a registration statement with respect (subject to
certain exceptions) to the exchange of the Outstanding Notes for debt securities
with terms identical in all material respects to the terms of the Outstanding
Notes. A copy of the Registration Agreement has been filed as an Exhibit to the
Registration Statement of which this Prospectus is a part.

      The Exchange Offer is being made to satisfy the contractual obligations of
the Company under the Registration Agreement. The form and terms of the Exchange
Notes are the same as the form and terms of the Outstanding Notes except that:
(i) the Exchange Notes have been registered under the Securities Act and
therefore will not be subject to certain restrictions on transfer applicable to
the Outstanding Notes and will not be entitled to resale registration under the
Registration Agreement, although the Registration Agreement does provide for
prospectus delivery procedures to assist resales of Exchange Notes, and (ii) the
Exchange Notes will not provide for any increase in the interest rate thereon.
In that regard, the Outstanding Notes provide that if (i) an exchange offer
registration statement or resale shelf registration statement is not filed by
October 1, 1997 or (ii) an exchange offer registration statement is not declared
effective by November 15, 1997, Special Interest will accrue and be payable
quarterly until such time as a registration statement is filed or becomes
effective, as the case may be. In addition, if (i) an exchange offer is not
consummated or a resale shelf registration statement is not declared effective
by December 31, 1997 or (ii) either the exchange offer registration statement or
the resale shelf registration statement has been declared effective and such
registration statement ceases to be effective or usable (subject to certain
exceptions), Special Interest will accrue and be payable quarterly until such
time as an exchange offer is consummated or a resale shelf registration
statement is declared effective, as the case may be. See "Description of the
Exchange Notes" and "Description of the Outstanding Notes."

      The Exchange Offer is not being made to, nor will the Company accept
tenders for exchange from, holders of Outstanding Notes in any jurisdiction in
which the Exchange Offer or the acceptance thereof would not be in compliance
with the securities or blue sky laws of such jurisdiction. Unless the context
requires otherwise, the term "holder" with respect to the Exchange Offer means
any person in whose name the Outstanding Notes are registered on the books of
the Company or any other person who has obtained a properly completed bond power
from the registered holder, or any person whose Outstanding Notes are held of
record by The Depository Trust Company who desires to deliver such Outstanding
Notes by book-entry transfer at The Depository Trust Company.

TERMS OF THE EXCHANGE

      The Company hereby offers, upon the terms and subject to the conditions
set forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange up to $36,000,000 aggregate principal amount of Exchange Notes for a
like aggregate principal amount of Outstanding Notes properly tendered on or
prior to the Expiration Date and not properly withdrawn in accordance with the
procedures described below. The Company will issue, promptly after the
Expiration Date, an aggregate principal amount of up to $36,000,000 of Exchange
Notes in exchange for a like principal amount of Outstanding Notes tendered and
accepted in connection with the Exchange Offer. Holders may tender their
Outstanding Notes in whole or in part in a principal amount of $1,000 and
integral multiples thereof.

      The Exchange Offer is not conditioned upon any minimum number of
Outstanding Notes being tendered. As of the date of this Prospectus $36,000,000
aggregate principal amount of the Outstanding Notes is outstanding.

                                       26
<PAGE>
      Holders of Outstanding Notes do not have any appraisal or dissenters'
rights in connection with the Exchange Offer. Outstanding Notes that are not
tendered for or are tendered but not accepted in connection with the Exchange
Offer will remain outstanding and be entitled to the benefits of the Indenture,
but will not be entitled to any further registration rights under the
Registration Agreement, except under limited circumstances. See "Risk Factors --
Consequences of a Failure to Exchange Outstanding Notes".

      If any tendered Outstanding Notes are not accepted for exchange because of
an invalid tender, or upon the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Outstanding Notes will
be returned, without expense, to the tendering holder thereof promptly after the
Expiration Date.

      Holders who tender Outstanding Notes in connection with the Exchange Offer
will not be required to pay brokerage commissions or fees or, subject to the
instructions in the Letter of Transmittal, transfer taxes with respect to the
exchange of Outstanding Notes in connection with the Exchange Offer. The Company
will pay all charges and expenses, other than certain applicable taxes described
below, in connection with the Exchange Offer. See "-- Fees and Expenses."

NEITHER THE BOARD OF DIRECTORS OF THE COMPANY NOR THE COMPANY MAKES ANY RECOMME
NDATION TO HOLDERS OF OUTSTANDI NG NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM
TENDERING ALL OR ANY PORTION OF THEIR OUTSTANDI NG NOTES PURSUANT TO THE
EXCHANGE OFFER. IN ADDITION, NO ONE HAS BEEN AUTHORIZE D TO MAKE ANY SUCH
RECOMME NDATION. HOLDERS OF OUTSTANDING NOTES MUST MAKE THEIR OWN DECISION
WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER AND, IF SO, THE AGGREGAT E
AMOUNT OF OUTSTANDI NG NOTES TO TENDER AFTER READING THIS PROSPECTU S AND THE
LETTER OF TRANSMITT AL AND CONSULTING WITH THEIR ADVISERS, IF ANY, BASED ON
THEIR OWN FINANCIAL POSITION AND REQUIREMENTS.

EXPIRATION DATE; EXTENSIONS; AMENDMENTS
   
      The term "Expiration Date" means 5:00 p.m., New York City time, on 
November 10, 1997 unless the Exchange Offer is extended by the Company (in which
case the term "Expiration Date" shall mean the latest date and time to which the
Exchange Offer is extended).
    
      The Company expressly reserves the right in its sole and absolute
discretion, subject to applicable law, at any time and from time to time, (i) to
delay the acceptance of the Outstanding Notes for exchange, (ii) to terminate
the Exchange Offer (whether or not any Outstanding Notes have theretofore been
accepted for exchange) if any of the events or conditions referred to under "--
Conditions to the Exchange Offer" have occurred or exist or have not been
satisfied, (iii) to extend the Expiration Date of the Exchange Offer and retain
all Outstanding Notes tendered pursuant to the Exchange Offer, subject, however,
to the right of holders of Outstanding Notes to withdraw their tendered
Outstanding Notes as described under "-- Withdrawal Rights," and (iv) to waive
any condition or otherwise amend the terms of the Exchange Offer in any respect.
If the Exchange Offer is amended in a manner determined by the Company to
constitute a material change, or if the Company waives a material condition of
the Exchange Offer, the Company will promptly disclose such amendment by means
of a prospectus supplement that will be distributed to the registered holders of
the Outstanding Notes, and the Company will extend the Exchange Offer to the
extent required by Rule 14e-1 under the Exchange Act.

      Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent and by
making a public announcement thereof, and

                                       27
<PAGE>
such announcement in the case of an extension will be made no later than 9:00
a.m., New York City time, on the next business day after the previously
scheduled Expiration Date. Without limiting the manner in which the Company may
choose to make any public announcement and subject to applicable law, the
Company shall have no obligation to publish, advertise or otherwise communicate
any such public announcement other than by issuing a release to an appropriate
news agency.

ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF EXCHANGE NOTES

      Upon the terms and subject to the conditions of the Exchange Offer, the
Company will exchange, and will issue to the Exchange Agent, Exchange Notes for
Outstanding Notes validly tendered and not withdrawn (pursuant to the withdrawal
rights described under "-- Withdrawal Rights") promptly after the Expiration
Date.

      In all cases, delivery of Exchange Notes in exchange for Outstanding Notes
tendered and accepted for exchange pursuant to the Exchange Offer will be made
only after timely receipt by the Exchange Agent of (i) Outstanding Notes or a
book-entry confirmation of a book-entry transfer of Outstanding Notes into the
Exchange Agent's account at the DTC, (ii) the Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, and (iii) any other documents required by the Letter of
Transmittal.

      The term "book-entry confirmation" means a timely confirmation of a
book-entry transfer of Outstanding Notes into the Exchange Agent's account at
DTC.

      Subject to the terms and conditions of the Exchange Offer, the Company
will be deemed to have accepted for exchange, and thereby exchanged, Outstanding
Notes validly tendered and not withdrawn as, if and when the Company gives oral
or written notice to the Exchange Agent of the Company's acceptance of such
Outstanding Notes for exchange pursuant to the Exchange Offer. The Exchange
Agent will act as agent for the Company for the purpose of receiving tenders of
Outstanding Notes, Letters of Transmittal and related documents, and as agent
for tendering holders for the purpose of receiving Outstanding Notes, Letters of
Transmittal and related documents and transmitting Exchange Notes to validly
tendering holders. Such exchange will be made promptly after the Expiration
Date. If for any reason whatsoever, acceptance for exchange or the exchange of
any Outstanding Notes tendered pursuant to the Exchange Offer is delayed
(whether before or after the Company's acceptance for exchange of Outstanding
Notes) or the Company extends the Exchange Offer or is unable to accept for
exchange or exchange Outstanding Notes tendered pursuant to the Exchange Offer,
then, without prejudice to the Company's rights set forth herein, the Exchange
Agent may, nevertheless, on behalf of the Company and subject to Rule 14e-1(c)
under the Exchange Act, retain tendered Outstanding Notes and such Outstanding
Notes may not be withdrawn except to the extent tendering holders are entitled
to withdrawal rights as described under "-- Withdrawal Rights."

      Pursuant to the Letter of Transmittal, a holder of Outstanding Notes will
warrant and agree in the Letter of Transmittal that it has full power and
authority to tender, exchange, sell, assign and transfer Outstanding Notes, that
the Company will acquire good, marketable and unencumbered title to the tendered
Outstanding Notes, free and clear of all liens, restrictions, charges and
encumbrance s, and the Outstanding Notes tendered for exchange are not subject
to any adverse claims or proxies. The holder also will warrant and agree that it
will, upon request, execute and deliver any additional documents deemed by the
Company or the Exchange Agent to be necessary or desirable to complete the
exchange, sale, assignment, and transfer of the Outstanding Notes tendered
pursuant to the Exchange Offer.

PROCEDURES FOR TENDERING OUTSTANDING NOTES

      VALID TENDER

      Except as set forth below, in order for Outstanding Notes to be validly
tendered pursuant to the Exchange Offer, the Exchange Agent must receive, at of
its address set forth under "--Exchange Agent," a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees and any other required documents (collectively, the "Letter
of Transmittal") and either (i) tendered Outstanding Notes, or (ii) Outstanding
Notes tendered pursuant to the procedures for book-entry transfer set forth
below and a book-entry confirmation, in each case on or prior to the Expiration
Date, or (iii) Outstanding Notes tendered in accordance with the guaranteed
delivery procedures set forth below.

      If less than all of the Outstanding Notes are tendered, a tendering holder
should fill in the amount of Outstanding Notes being tendered in the appropriate
box on the Letter of Transmittal. The entire amount of Outstanding Notes
delivered to the Exchange Agent will be deemed to have been tendered unless
otherwise indicated.

      THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER,
AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL, RETURN RECEIPT REQUESTED,
PROPERLY INSURED, OR AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

      BOOK ENTRY TRANSFER

      The Exchange Agent will establish an account with respect to the
Outstanding Notes at DTC for purposes of the Exchange Offer within two business
days after the date of this Prospectus. Any financial institution that is a
participant in DTC's book-entry transfer facility system may make a book-entry
delivery of the Outstanding Notes by causing DTC to transfer such Outstanding
Notes into the Exchange Agent's account at DTC in accordance with DTC's
procedures for transfers. However, although delivery of Outstanding Notes may be
effected through book-entry transfer into the Exchange Agent's account at DTC,
the Letter of Transmittal must in any case be delivered to and received by the
Exchange Agent at the Exchange Agent's address set forth under "-- Exchange
Agent" on or prior to the Expiration Date, or the guaranteed delivery procedure
set forth below must be complied with.
   
      DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT. THE LETTER OF TRANSMITTAL MUST BE
RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO November 10, 1997.
    
      SIGNATURE GUARANTEES

      Certificates for the Outstanding Notes need not be endorsed and signature
guarantees on the Letter of Transmittal are unnecessary unless (a) a certificate
for the Outstanding Notes is registered in a name other than that of the person
surrendering the certificate or (b) such registered holder completes the box
entitled "Special Issuance Instructions" or "Special Delivery Instructions" in
the Letter of Transmittal. In the case of (a) or (b) above, such certificates
for Outstanding Notes must be duly endorsed or accompanied by a properly
executed bond power, with the endorsement or signature on the bond power and on
the Letter of Transmittal guaranteed by a firm or other entity identified in
Rule 17Ad-15 under the Exchange 

                                       29
<PAGE>
Act as an "eligible guarantor" institution, including (as such terms are defined
therein): (i) a bank; (ii) a broker, dealer, municipal securities broker or
dealer or government securities broker or dealer; (iii) a credit union; (iv) a
national securities exchange, registered securities association or clearing
agency; or (v) a savings association that is a participant in a Securities
Transfer Association (an "Eligible Institution"), unless surrendered on behalf
of such Eligible Institution. See Instruction 1 to the Letter of Transmittal.

GUARANTEED DELIVERY

      If a holder desires to tender Outstanding Notes pursuant to the Exchange
Offer and the certificates for such Outstanding Notes are not immediately
available or time will not permit the Letter of Transmittal to reach the
Exchange Agent on or before the Expiration Date, or the procedures for
book-entry transfer cannot be completed on a timely basis, such Outstanding
Notes may nevertheless be tendered, provided that all of the following
guaranteed delivery procedures are complied with:


            (i) such tenders are made by or through an Eligible Institution;

            (ii) a properly completed and duly executed Notice of Guaranteed
      Delivery, substantially in the form accompanying the Letter of
      Transmittal, is received by the Exchange Agent, as provided below, on or
      prior to Expiration Date; and

            (iii) the certificates (or a book-entry confirmation) representing
      all tendered Outstanding Notes, in proper form for transfer, together with
      a properly completed and duly executed Letter of Transmittal, are received
      by the Exchange Agent within five New York Stock Exchange trading days
      after the date of execution of such Notice of Guaranteed Delivery.

      The Notice of Guaranteed Delivery may be delivered by hand, or transmitted
by facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in such notice.

      Notwithstanding any other provision hereof, the delivery of Exchange Notes
in exchange for Outstanding Notes tendered and accepted for exchange pursuant to
the Exchange Offer will in all cases be made only after timely receipt by the
Exchange Agent of Outstanding Notes, or of a book-entry confirmation with
respect to such Outstanding Notes, and a properly completed and duly executed
Letter of Transmittal (or facsimile thereof). Accordingly, the delivery of
Exchange Notes might not be made to all tendering holders at the same time, and
will depend upon when Outstanding Notes, book-entry confirmations with respect
to Outstanding Notes and other required documents are received by the Exchange
Agent.

      The Company's acceptance for exchange of Outstanding Notes tendered
pursuant to any of the procedures described above will constitute a binding
agreement between the tendering holder and the Company upon the terms and
subject to the conditions of the Exchange Offer.

DETERMINATION OF VALIDITY

      All questions as to the form of documents, validity, eligibility
(including time of receipt) and acceptance for exchange of any tendered
Outstanding Notes will be determined by the Company, in its sole discretion,
whose determination shall be final and binding on all parties. The Company
reserves the absolute right, in its sole and absolute discretion, to reject any
and all tenders determined by it not to be in proper form or the acceptance of
which, or exchange for, may, in the view of counsel to the Company, be unlawful.
The Company also reserves the absolute right, subject to applicable law, to
waive any of the conditions of the Exchange Offer as set forth under "--
Conditions to the Exchange Offer" or any 

                                       30
<PAGE>
condition or irregularity in any tender of Outstanding Notes of any particular
holder whether or not similar conditions or irregularities are waived in the
case of other holders.

      The Company's interpretation of the terms and conditions of the Exchange
Offer (including the Letter of Transmittal and the instructions thereto) will be
final and binding. No tender of Outstanding Notes will be deemed to have been
validly made until all irregularities with respect to such tender have been
cured or waived. Neither the Company, any affiliates or assigns of the Company,
the Exchange Agent nor any other person shall be under any duty to give any
notification of any irregularities in tenders or incur any liability for failure
to give any such notification.

      If any Letter of Transmittal, endorsement, bond power, power of attorney,
or any other document required by the Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in- fact, officer of a
corporation or other person acting in a fiduciary or representative capacity
such person should so indicate when signing, and unless waived by the Company,
proper evidence satisfactory to the Company, in its sole discretion, of such
person's authority to so act must be submitted.

      A beneficial owner of Outstanding Notes that are held by or registered in
the name of a broker, dealer, commercial bank, trust company or other nominee or
custodian is urged to contact such entity promptly if such beneficial holder
wishes to participate in the Exchange Offer.

RESALES OF EXCHANGE NOTES

      The Company is making the Exchange Offer in reliance on a position of the
staff of the Division of Corporation Finance of the Commission as set forth in
certain interpretive letters addressed to third parties in other transactions.
However, the Company has not sought its own interpretive letter and there can be
no assurance that the staff of the Division of Corporation Finance of the
Commission would make a determination with respect to the Exchange Offer similar
to that made in such interpretive letters to third parties. Based on these
interpretations by the staff of the Division of Corporation Finance, and subject
to the two immediately following sentences, the Company believes that Exchange
Notes issued pursuant to this Exchange Offer in exchange for Outstanding Notes
may be offered for resale, resold and otherwise transferred by a holder thereof
(other than a holder who is a broker-dealer) without further compliance with the
registration and prospectus delivery requirements of the Securities Act,
provided that such Exchange Notes are acquired in the ordinary course of such
holder's business and that such holder is not participating, and has no
arrangement or understanding with any person to participate, in a distribution
(within the meaning of the Securities Act) of such Exchange Notes. However, any
holder of Outstanding Notes who is an "affiliate" of the Company or who intends
to participate in the Exchange Offer for the purpose of distributing Exchange
Notes, or any broker-dealer who purchased Outstanding Notes from the Company to
resell pursuant to Rule 144A or any other available exemption under the
Securities Act, (a) will not be able to rely on the interpretations of the staff
of the Division of Corporation Finance of the Commission set forth in the
above-mentioned interpretive letters, (b) will not be permitted or entitled to
tender such Outstanding Notes in the Exchange Offer and (c) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale or other transfer of such Outstanding Notes unless such
sale is made pursuant to an exemption from such requirements. In addition, as
described below, if any broker-dealer holds Outstanding Notes acquired for its
own account as a result of market- making or other trading activities and
exchanges such Outstanding Notes for Exchange Notes, then such broker-dealer
must deliver a prospectus meeting the requirements of the Securities Act in
connection with any resales of such Exchange Notes. In the event that applicable
interpretations by the staff of the Division of Corporation Finance change or
otherwise do not permit resales of the Exchange Notes without compliance with
the registration and prospectus delivery requirements of the Securities Act,
holders of Exchange Notes who transfer Exchange Notes in violation of the
prospectus delivery

                                       31
<PAGE>
requirements of the Securities Act or without an exemption from registration
thereunder may incur liability thereunder.

      Each holder of Outstanding Notes who wishes to exchange Outstanding Notes
for Exchange Notes in the Exchange Offer will be required to represent that (i)
it is not an affiliate of the Company, (ii) any Exchange Notes to be received by
it are being acquired in the ordinary course of its business, (iii) it has no
arrangement or understanding with any person to participate in a distribution
(within the meaning of the Securities Act) of such Exchange Notes, and (iv) if
such holder is not a broker-dealer, such holder is not engaged in, and does not
intend to engage in, a distribution (within the meaning of the Securities Act)
of such Exchange Notes. Each broker-dealer that receives Exchange Notes for its
own account pursuant to the Exchange Offer must acknowledge that it acquired the
Outstanding Notes for its own account as the result of market-making activities
or other trading activities and must agree that it will deliver a prospectus
meeting the requirements of the Securities Act in connection with any resale of
such Exchange Notes. The Letter of Transmittal states that by so acknowledgin g
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. Based on the
position taken by the staff of the Division of Corporation Finance of the
Commission in the interpretive letters referred to above, the Company believes
that broker-dealers who acquired Outstanding Notes for their own accounts as a
result of market-making activities or other trading activities (Participating
Broker- Dealers) may fulfill their prospectus delivery requirements with respect
to the Exchange Notes received upon exchange of such Outstanding Notes (other
than Outstanding Notes that represent an unsold allotment from the original sale
of the Outstanding Notes) with a prospectus meeting the requirements of the
Securities Act, which may be the prospectus prepared for an exchange offer so
long as it contains a description of the plan of distribution with respect to
the resale of such Exchange Notes. Accordingly, this Prospectus, as it may be
amended or supplemented from time to time, may be used by a Participating
Broker-Dealer during the period referred to below in connection with resales of
Exchange Notes received in exchange for Outstanding Notes where such Outstanding
Notes were acquired by such Participating Broker-Dealer for its own account as a
result of market-making or other trading activities. Subject to certain
provisions set forth in the Registration Agreement, the Company has agreed that
this Prospectus, as it may be amended or supplemented from time to time, may be
used by a Participating Broker-Dealer in connection with resales of such
Exchange Notes for a period ending forty-five days after the consummation of the
Exchange Offer or, if earlier, when all such Exchange Notes have been disposed
of by such Participating Broker- Dealer. See "Plan of Distribution." Any
Participating Broker-Dealer who is an "affiliate" of the Company may not rely on
such interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.

      In that regard, each Participating Broker-Dealer who surrenders
Outstanding Notes pursuant to the Exchange Offer will be deemed to have agreed,
by execution of the Letter of Transmittal, that, upon receipt of notice from the
Company of the occurrence of any event or the discovery of any fact which makes
any statement contained in this Prospectus untrue in any material respect or
which causes this Prospectus to omit to state a material fact necessary in order
to make the statements herein, in light of the circumstances under which they
were made, not misleading or of the occurrence of certain other events specified
in the Registration Agreement, such Participating Broker-Dealer will suspend the
sale of Exchange Notes pursuant to this Prospectus until the Company has amended
or supplemented this Prospectus to correct such misstatement or omission and has
furnished copies of the amended or supplemented Prospectus to such Participating
Broker-Dealer or the Company has given notice that the sale of the Exchange
Notes may be resumed, as the case may be. If the Company gives such notice to
suspend the sale of the Exchange Notes, it shall extend the forty-five day
period referred to above during which Participating Broker- Dealers are entitled
to use this Prospectus in connection with the resale of Exchange Notes by the
number of days during the period from and including the date of the giving of
such notice to and including the date when Participating Broker- Dealers shall
have received copies of the

                                       32
<PAGE>
amended or supplemented Prospectus necessary to permit resales of the Exchange
Notes or to and including the date on which the Company has given notice that
the sale of Exchange Notes may be resumed, as the case may be.

WITHDRAWAL RIGHTS

      Except as otherwise provided herein, tenders of Outstanding Notes may be
withdrawn at any time on or prior to the Expiration Date.

      In order for a withdrawal to be effective, a written, telegraphic, telex
or facsimile transmission of such notice of withdrawal must be timely received
by the Exchange Agent at its address set forth under "-- Exchange Agent" on or
prior to the Expiration Date. Any such notice of withdrawal must specify the
name of the person who tendered the Outstanding Notes to be withdrawn, the
aggregate principal amount of Outstanding Notes to be withdrawn, and (if
certificates for such Outstanding Notes have been tendered) the name of the
registered holder of the Outstanding Notes as set forth on the Outstanding
Notes, if different from that of the person who tendered such Outstanding Notes.
If Outstanding Notes have been delivered or otherwise identified to the Exchange
Agent, then prior to the physical release of such Outstanding Notes, the
tendering holder must submit the serial numbers shown on the particular
Outstanding Notes to be withdrawn and the signature on the notice of withdrawal
must be guaranteed by an Eligible Institution, except in the case of Outstanding
Notes tendered for the account of an Eligible Institution. If Outstanding Notes
have been tendered pursuant to the procedures for book-entry transfer set forth
in "-- Procedures for Tendering Outstanding Notes," the notice of withdrawal
must specify the name and number of the account at DTC to be credited with the
withdrawal of Outstanding Notes, in which case a notice of withdrawal will be
effective if delivered to the Exchange Agent by written, telegraphic, telex or
facsimile transmission. Withdrawals of tenders of Outstanding Notes may not be
rescinded. Outstanding Notes properly withdrawn will not be deemed validly
tendered for purposes of the Exchange Offer, but may be retendered at any
subsequent time on or prior to the Expiration Date by following any of the
procedures described above under "-- Procedures for Tendering Outstanding
Notes."

      All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all parties.
Neither the Company, any affiliates or assigns of the Company, the Exchange
Agent nor any other person shall be under any duty to give any notification of
any irregularities in any notice of withdrawal or incur any liability for
failure to give any such notification. Any Outstanding Notes which have been
tendered but which are withdrawn will be returned to the holder thereof promptly
after withdrawal.

INTEREST ON THE EXCHANGE NOTES

      Each Exchange Note will bear interest at the rate of 10.125% per annum
from the most recent date to which interest has been paid or duly provided for
on the Outstanding Note surrendered in exchange for such Exchange Note or, if no
interest has been paid or duly provided for on such Outstanding Note, from July
31, 1997 (the date of original issuance of such Outstanding Notes). Interest on
the Exchange Notes will be payable quarterly on September 15, December 15, March
15 and June 15 of each year, commencing on the first such date following the
original issuance date of the Exchange Notes.

      Holders of Outstanding Notes whose Outstanding Notes are accepted for
exchange will not receive accrued interest on such Outstanding Notes for any
period from and after the last interest payment date to which interest has been
paid or duly provided for on such Outstanding Notes prior to the original issue
date of the Exchange Notes or, if no such interest has been paid or duly
provided for, will not receive any accrued interest on such Outstanding Notes,
and will be deemed to have waived the right to receive any

                                       33
<PAGE>
interest on such Outstanding Notes accrued from and after such interest payment
date or, if no such interest has been paid or duly provided for, from and after
July 31, 1997.

CONDITIONS TO THE EXCHANGE OFFER

      Notwithstanding any other provisions of the Exchange Offer, or any
extension of the Exchange Offer, the Company will not be required to accept for
exchange, or to exchange, any Outstanding Notes for any Exchange Notes, and, as
described below, may terminate the Exchange Offer (whether or not any
Outstanding Notes have theretofore been accepted for exchange), or may waive any
conditions to or amend the Exchange Offer, if any of the following conditions
have occurred or exist or have not been satisfied:

            (a) the Exchange Offer, or the making of any exchange pursuant to
      the Exchange Offer, violates applicable law or any applicable
      interpretation of the staff of the Commission; or

            (b) any action or proceeding shall have been instituted or
      threatened in any court or by or before any governmental agency or body
      with respect to the Exchange Offer; or

            (c) any law, statute, rule or regulation shall have been adopted or
      enacted prohibiting or limiting the Exchange Offer; or

            (d) a banking moratorium shall have been declared by United States
      federal, New York or Texas state authorities; or

            (e) trading on the New York Stock Exchange or generally in the
      United States over-the-counter market shall have been suspended by order
      of the Commission or any other governmental authority; or

            (f) such other conditions reasonably acceptable to the Initial
      Purchaser which, in the Company's judgment, would reasonaly be expected to
      impair the ability of the Company to proceed with the Exchange Offer.

      If the Company determines in its sole and absolute discretion that any of
the foregoing events or conditions has occurred or exists or has not been
satisfied, the Company may, subject to applicable law and the provisions of the
Registration Agreement, terminate the Exchange Offer (whether or not any
Outstanding Notes have theretofore been accepted for exchange) or may waive any
such condition or otherwise amend the terms of the Exchange Offer in any
respect. If such waiver or amendment constitutes a material change to the
Exchange Offer, the Company will promptly disclose such waiver by means of a
prospectus supplement that will be distributed to the registered holders of the
Outstanding Notes, and the Company will extend the Exchange Offer to the extent
required by Rule 14e-1 under the Exchange Act.

EXCHANGE AGENT

      American Stock Transfer & Trust Company has been appointed as Exchange
Agent for the Exchange Offer. Delivery of the Letter of Transmittal and any
other required documents, questions, requests for assistance, and requests for
additional copies of this Prospectus or of the Letter of Transmittal should be
directed to the Exchange Agent as follows:

                                       34
<PAGE>
                     American Stock Transfer & Trust Company
                                 40 Wall Street
                               New York, New York
                            718-921-8206 (Telephone)
                            718-921-8336 (Facsimile)

      Delivery to other than the above address or facsimile number will not
constitute a valid delivery.

FEES AND EXPENSES

      The Company has agreed to pay the Exchange Agent reasonable and customary
fees for its services and will reimburse it for its reasonable out-of-pocket
expenses in connection therewith. The Company will also pay brokerage houses and
other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus and related documents
to the beneficial owners of Outstanding Notes, and in handling or tendering for
their customers.

      Holders who tender their Outstanding Notes for exchange will not be
obligated to pay any transfer taxes in connection therewith. If, however,
Exchange Notes are to be delivered to, or are to be issued in the name of, any
person other than the registered holder of the Outstanding Notes tendered, or if
a transfer tax is imposed for any reason other than the exchange of Outstanding
Notes in connection with the Exchange Offer, then the amount of any such
transfer taxes (whether imposed on the registered holder or any other persons)
will be payable by the tendering holder. If satisfactory evidence of payment of
such taxes or exemption therefrom is not submitted with the Letter of
Transmittal, the amount of such transfer taxes will be billed directly to such
tendering holder.

      The Company will not make any payment to brokers, dealers or others
soliciting acceptances of the Exchange Offer.

                                 USE OF PROCEEDS

      The net proceeds to the Company from the sale of the Outstanding Notes was
$34.8 million. The Company used $18.5 million of the net proceeds of the
offering of the Outstanding Notes to repay borrowings under the Credit Facility.
Approximately $11.8 million of such borrowings under the Credit Facility were
incurred to finance the acquisition from Elf Exploration of a working interest
in Mobile Area Block 864 Unit in June 1997. The Company intends to use the
remaining net proceeds together with internally generated cash flows and
borrowings under its Credit Facility, to fund its capital expenditure budget for
the last six months of 1997 estimated to be approximately $25 million. See
"Management 's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." Pending the use of funds to pay
capital expenditures, the Company will invest in short-term investments. As of
June 30, 1997, $18.6 million was outstanding under the Credit Facility with a
weighted average interest rate of 6.70%.

      The Exchange Offer is intended to satisfy certain of the Company's
obligations under the Registration Agreement. The Company will not receive any
cash proceeds from the issuance of the Exchange Notes in the Exchange Offer. In
consideration for issuing the Exchange Notes as contemplated in this Prospectus,
the Company will receive Outstanding Notes in like principal amount. The form
and terms of the Exchange Notes are identical in all material respects to the
form and terms of the Outstanding Notes, except certain transfer restrictions
and registration rights relating to the Outstanding Notes and except for certain
interest provisions relating to such registration rights. See "Description of
the Exchange Notes." The Outstanding Notes surrendered in exchange for the
Exchange Notes will be retired and 

                                       35
<PAGE>
canceled and cannot be reissued. Accordingly, issuance of the Exchange Notes
will not result in any increase in the outstanding debt of the Company.

                                 CAPITALIZATION

      The following table sets forth the capitalization of the Company as of
June 30, 1997 and as adjusted to give effect to the issuance and sale of the
Notes and the application of the net proceeds therefrom as described in "Use of
Proceeds." This table should be read in conjunction with the Company's
Consolidated Financial Statements, including the notes thereto, and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" found elsewhere in this Prospectus. Issuance of the Exchange Notes
will not affect the Company's consolidated capitalization.

                                                          JUNE 30, 1997

                             SELECTED FINANCIAL DATA

      The following table sets forth, as of the dates and for the periods
indicated, selected financial information for the Company. The financial data
for each of the five years in the period ended December 31, 1996 have been
derived from the audited Consolidated Financial Statements of the Company for

(1)   The Company succeeded to the business and properties of Callon Petroleum
      Operating, CCP and CN on September 16, 1994 pursuant to the Consolidation.
      Historical information about the Company prior to September 16, 1994
      includes the financial and operating information of the predecessors of
      the Company, other than the interest in CN not owned by Callon Petroleum
      Operating, combined as entities under common control in a manner similar
      to a pooling of interests. See "The Company."
(2)   EBITA is earnings before interest, taxes, depreciation, depletion and
      amortization. EBITDA is presented because it is a widely accepted
      financial indication of a company's ability to service and incur debt.
      EBITDA should not be considered as an alternative to earnings (loss) as an
      indicator of the Company's operating performance or to cash flow as a
      measure of liquidity.
(3)   For purpose of computing this ratio, "earnings" represent income (loss)
      before income taxes and extraordinary item plus fixed charges. "Fixed
      charges" consist of interest expense on all indebtedness and that portion
      of rental expense considered to be representative of the interest factor
      therein. As a result of the loss incurred for the year ended December 31,
      1994, earnings did not cover fixed charges by $313,000.

           MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS

GENERAL

      The Company's revenues, profitability and future growth and the carrying
value of its oil and gas properties are substantially dependent on prevailing
prices of oil and gas. The Company's ability to maintain or increase its
borrowing capacity and to obtain additional capital on attractive terms is also
substantially dependent upon oil and gas prices. Prices for oil and gas are
subject to large fluctuation 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 regulation, 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.

      Volatile oil and gas prices make it difficult to estimate the value of
producing properties for acquisition and often cause disruption in the market
for oil and gas producing properties, as buyers and sellers have difficulty
agreeing on such value. Price volatility also makes it difficult to budget for
and project the return on acquisitions and development and exploitation
projects.

      The Company uses the full cost method of accounting for the Company's
investment in oil and gas properties. Under the full cost method of accounting,
all costs of acquisition, exploration and development of oil and gas reserves
are capitalized into a "full cost pool." Oil and gas properties in the pool,
plus estimated future expenditures to develop proved reserves and future
abandonment, site remediation and dismantlement costs, are depleted and charged
to operations using the unit of production method based on the ratio of current
production to total estimated proved recoverable oil and gas reserves. To the
extent that such capitalized costs (net of depreciation, depletion and
amortization) exceed the discounted future net cash flows on an after-tax basis
of estimated proved oil and gas reserves, such excess costs are charged to
operations. Once incurred, the write-down of oil and gas properties is not
reversible at a later date even if oil or natural gas prices increase.

      SIX MONTHS ENDED JUNE 30, 1997 COMPARED WITH SIX MONTHS ENDED JUNE 30,
      1996

      For the six months ended June 30, 1997, total oil and gas revenues
increased by $8.6 million, or 70%, to $20.8 million when compared to $12.2
million for the same period in 1996.

      For the six months ending June 30, 1997, oil production and oil revenues
decreased to 237 MBbls and $4.6 million, respectively. For the comparable period
in 1996, oil production was 302 MBbls while revenues totaled $5.5 million. Oil
prices during the first six months of 1997 averaged $19.36, compared to $18.12
for the same period in 1996. Although prices were higher, the loss of production
from properties which were sold and a production decline in other non-core
properties caused the overall decline in oil revenues.

                                       40
<PAGE>
      Natural gas production and revenue for the six-month period ending June
30, 1997 were 6.4 Bcf and $16.3 million, respectively, increasing from 2.9 Bcf
and gas revenues of $6.8 million in the first six months of 1996. The average
sales price for natural gas in the first six months in 1997 was $2.52 per Mcf, a
$0.19 per Mcf increase over the same period in 1996. The combination of
increased prices and production volumes generated the 140% increase in total gas
revenues.

      Lease operating expenses, excluding severance taxes, for the first half of
1997 increased by 26% to $3.4 million from $2.7 million for the 1996 comparable
period. This increase is primarily the result of expenses associated with
producing properties acquired in the first quarter. Severance taxes decreased by
22% to $0.7 million during the first six months of 1997 from $0.9 million for
the same period in 1996 as a result of production declines attributable to the
Company's onshore properties and property sales.

      Depreciation, depletion and amortization for the first six months of 1997
was $7.6 million, or $0.96 per Mcfe. For the same period in 1996, the total was
$4.8 million or $1.03 per Mcfe.

      During the first six months of 1997, general and administrative expenses
increased by 40% to $2.4 million compared to $1.7 million for the six-month
period in 1996. Increased executive compensation, travel and transportation
expenses and the loss of management fees, as a result of property sales,
combined to produce this overall increase.

      Interest expense during the first half of 1997 was $210,000 compared to
$48,000 for the first half of 1996 as a result of the increase in the Company's
long-term debt.

      YEAR ENDED DECEMBER 31, 1996 COMPARED WITH THE YEAR ENDED DECEMBER 31,
      1995

      Oil and gas sales increased $2.6 million, or 11%, during 1996 to $25.8
million compared to $23.2 million in 1995. While oil and gas production volumes
for 1996 were lower than those reported in 1995, substantial price increases for
both oil and gas more than offset the loss in revenues. The average sales price
per barrel sold in 1996 increased to $18.27, compared to $16.68 for 1995. The
average sales price per Mcf of gas sold increased from $1.96 in 1995 to $2.40 in
1996.

      Oil production for 1996 decreased slightly to 585,000 Bbls from the
594,000 Bbls produced in 1995. This reduction was primarily attributable to the
implementation of the required environmental protection program (zero discharge)
at the Black Bay Complex, the Company's largest single oil producing prospect.
During this process, several producing wells were shut-in while various new
equipment was installed. In addition, several wells were temporarily shut-in
while repairs were conducted on the service lines. Therefore, average daily
production for 1996 dropped to 1,599 Bbls/d compared to 1,629 Bbls/d in 1995.

      Gas production for 1996 was 6.3 Bcf, a decrease from the 6.7 Bcf reported
in 1995. This reduction was primarily attributable to the loss of production
from the North Dauphin Island Field where problems with excess water content in
the gas sales stream were encountered early in the year requiring the
installation of a dehydrator and removal of water from the lines. Extraneous
water production from the #2A well led to the shut-in of the well and the
natural decline of the reservoir pressure. Also during the year, this field
incurred a lower production rate due to compressor inefficiencies which led to a
compressor restaging program that was completed in late September.

      Lease operating expenses, including severance taxes, increased from $6.7
million in 1995 to $7.6 million in 1996. A large portion of this increase,
$600,000, is attributable to normal expenses associated

                                       41
<PAGE>
with new property additions. Other expenses included the installation of a
dehydrator and the workover expenses at the North Dauphin Island Field.

      Depreciation, depletion and amortization expense for 1996 was $9.8 million
compared to $10.4 million for 1995. When compared on a per unit-of-production
basis, the expense incurred was $1.01 per Mcfe produced for each of the two
years.

      General and administrative expenses declined from $3.9 million for 1995 to
$3.5 million for 1996, as a result of the Company's continued efforts to improve
operational efficiencies.

      Interest expense decreased from $1.8 million in 1995 to $313,000 in 1996.
This expense reduction corresponds with the smaller average monthly outstanding
balance on the long-term debt of the Company for 1995 when compared to 1996.
During the fourth quarter of 1995, the Company used $21.5 million of the
proceeds from the sale of preferred stock to reduce its long-term debt. During
the course of 1996, additional funds advanced under the Company's line of credit
were repaid in November when the Company issued $24.2 million of its Existing
Notes. The average outstanding balance in long-term debt during 1996 was $5.3
million.

      The recorded income tax expense for 1996 was $50,000. The computed
provision for income taxes at the Company's expected statutory rate was $1.9
million, which was primarily offset by a reduction in the deferred tax asset
valuation allowance as a result of the Company's ability to utilize its net
operating losses and depletion carryovers.

      YEAR ENDED DECEMBER 31, 1995 COMPARED WITH THE YEAR ENDED DECEMBER 31,
      1994

      Oil and gas sales increased $9.3 million, or 66%, during 1995 to $23.2
million compared with $13.9 million in 1994. This increase is partially
attributable to the Company's purchase in September 1994 of NOCO's interest in
CN pursuant to the Consolidation as well as the acquisition of certain
properties from W&T Offshore, Inc. ("1994 Properties"). The Company's purchase
of the Escambia Minerals properties in June 1995 also contributed $1.9 million
to the increase in oil and gas sales.

      Oil production attributable to the NOCO Interest, the Escambia Minerals
properties and the 1994 Properties substantially outweighed normal production
declines in previously existing properties, as oil production for 1995 increased
to 594 MBbls from the 1994 level of 364 MBbls. The average price per barrel sold
also increased by $1.05 in 1995 compared to 1994 prices, resulting in a total
$4.3 million increase in oil revenues.

      Total gas production increased 2.6 Bcf to 6.7 Bcf in 1995 from 4.1 Bcf in
1994. A substantial portion of this increase in production was attributable to
the Company's acquisition of the North Dauphin Island Field. Gas production from
the North Dauphin Island Field increased from 2.5 Bcf in 1994 to 5.1 Bcf in 1995
and added $5.0 million in revenues in 1995 compared with 1994. Although spot
market gas prices declined in 1995, gas price hedges limited the effect of the
decline to $0.04 per Mcf.

      Lease operating expenses, including production taxes, increased 67% during
1995 to $6.7 million, compared to $4.0 million for 1994. This increase was
largely attributable to the corresponding increase in oil and gas production
caused by the Company's acquisition of the NOCO Interest, the Escambia Minerals
properties and the 1994 Properties. The Company's purchase of the NOCO Interest
in September 1994 resulted in an increase in combined lease operating expenses
attributable to the North Dauphin Island Field and the Black Bay Complex from
$1.5 million in 1994 to $3.6 million in 1995. Lease operating expenses on a Mcfe
basis increased by less than 2% to $0.66 for 1995 compared to $0.65 for 1994.

                                       42
<PAGE>
      Total depreciation, depletion and amortization expense was $10.4 million
for 1995, compared to $6.0 million for 1994. This increase reflects additional
production and reserves resulting from the purchase of the NOCO Interest, the
Escambia Minerals properties and the 1994 Properties.

      General and administrative expenses were $3.9 million for 1995, compared
to $3.7 million in 1994. The increase was primarily attributable to the
Company's expanding operations.

      The Company had a zero effective tax rate for 1995, compared to an
effective rate of (63)% in 1994. The 1995 rate was primarily due to a reduction
in the deferred tax asset valuation allowance of $551,000. The valuation
allowance was reduced during 1995 due to a reduction in the gross deferred tax
asset. This valuation allowance represents the portion of federal net operating
loss carry forward and other temporary differences which the Company believes
will not be utilized.

LIQUIDITY AND CAPITAL RESOURCES

    CAPITAL SOURCES

      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. Cash provided from operations during 1996 totaled $15.8
million. During 1996, the Company borrowed $12.9 million from financial
institutions and repaid such borrowing with the proceeds from the sale of $24.2
million of Existing Notes during November, 1996. At December 31, 1996, the
Company had working capital in the amount of $4.9 million. Net cash provided by
operating activities for the six months ending June 30, 1997 totaled $17.2
million. During the first half of 1997, a total of $36.2 million was paid for
capital expenditures and $1.4 million was paid as dividends to the preferred
stockholders. The balance of the cash flow was retained for future operating
expenses and potential drilling and acquisition opportunities.

      Effective October 31, 1996, the Company entered into a new Credit Facility
with Chase Manhattan Bank. Borrowings under the Credit Facility are secured by
mortgages covering substantially all of the Company's producing oil and gas
properties. The Credit Facility provides for borrowings of a maximum of the
lesser of $50 million or a borrowing base ("Borrowing Base") of $30 million
which is adjusted periodically on the basis of a discounted present value of
future net cash flows attributable to the Company's proved producing oil and gas
reserves. Pursuant to the Credit Facility, depending upon the percentage of the
unused portion of the Borrowing Base, the interest rate is equal to either the
lender's prime rate or the lender's prime rate plus 0.50%. The Company, at its
option, may fix the interest rate on all or a portion of the outstanding
principal balance at either 1.00% or 1.375% above a defined "Eurodollar" rate,
depending upon the percentage of the unused portion of the Borrowing Base, for
periods of up to six months. The weighted average interest rate for the total
debt outstanding at December 31, 1996 was 8.25%. Under the Credit Facility, a
commitment fee of .25% or .375% per annum on the unused portion of the Borrowing
Base (depending upon the percentage of the unused portion of the Borrowing Base)
is payable quarterly. The Company may borrow, pay, reborrow and repay under the
Credit Facility until October 31, 2000, on which date, the Company must repay in
full all amounts then outstanding. At June 30, 1997, the unpaid balance due on
this Credit Facility was $18.6 million.

      On November 27, 1996, the Company issued $24.2 million of Existing Notes.
The Company used the proceeds to pay down the Credit Facility and for other
corporate purposes. Interest on the Existing Notes is payable quarterly and
began on March 15, 1997. The Existing Notes are redeemable at the option of the
Company, in whole or in part, on or after December 15, 1997, at 100% of the
principal amount thereof, plus accrued interest to the redemption date. The
Existing Notes are general unsecured obligations of the Company, subordinated in
right of payment to all existing and future indebtedness of the Company and rank
PARI PASSU with the Notes. The Credit Facility and the indentures for the
Existing

                                       43
<PAGE>
Notes contain, and the indenture for the Notes will contain, various covenants
including restrictions on additional indebtedness and payment of cash dividends
as well as maintenance of certain financial ratios.

      The Company periodically uses derivative financial instruments to manage
oil and gas price risk. Settlements of gains and losses on commodity price swap
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, and are reported as a component of oil and gas revenues.
Gains or losses attributable to the termination of a swap contract are deferred
and recognized in revenue when the oil and gas is sold. From October 1, 1996 to
March 31, 1997, the Company had in effect hedges of gas equivalent to
approximately 16% of its production at a floor price per MMBtu of $1.75 (NYMEX)
and a ceiling price per MMBtu of $ 2.20 (NYMEX). In addition, the Company was
party to hedges in effect from October 1, 1996 through December 31, 1996
representing approximately 81% of its oil production at a floor price per Bbl of
$17.25 (NYMEX) and a ceiling price per Bbl of $19.59 (NYMEX). During the third
quarter of 1996, the Company terminated hedges attributable to its fourth
quarter 1996 production at a profit, which had the effect of increasing fourth
quarter oil and gas revenues by $180,000. The Company is currently a party to
hedges that will be in effect for the last six months of 1997 representing
approximately 27% of its estimated oil production, at a floor price of $18.00
per Bbl (NYMEX) and a ceiling price per Bbl of $24.00 (NYMEX). In addition, from
July 1997 through March 1998, the Company has hedged 30% of its estimated
natural gas equivalent production at an average floor price of $2.00 per MMBtu
(NYMEX) and an average ceiling price of $2.66 per MMBtu (NYMEX).

CAPITAL EXPENDITURES

      Capital expenditures for 1996 totaled $36.1 million which included $19.2
million of lease acquisitions, $2.7 million for the acquisition of producing
properties and equipment and $14.2 million for property development and drilling
activities on its properties. During the first half of 1997, capital
expenditures were $36.2 million. Of such amount, approximately $12.0 million was
expended on drilling and exploration activities and $22.0 million on
acquisitions of producing properties, undeveloped mineral interests and seismic
information attributable to future drilling sites.

      The Company has recently shifted the focus of its reserve growth strategy
from the acquisition and exploitation of oil and gas properties to exploration
and development drilling. For the second half of 1997, the Company expects to
concentrate its exploration and development drilling in the Shallow Gas focus
area and the Breton Sound focus area. The Company has identified two gross (1.5
net) development and seven gross (3.3 net) exploratory drilling locations for
drilling in the second half of 1997, and the Company's capital budget includes
$21.2 million to drill and complete these wells. The Company's capital budget
for the remainder of 1997 will depend upon the success of its exploration and
development drilling. If the Company's exploration drilling operations are
successful, it may require additional capital to develop discoveries during late
1997 and thereafter. If the Company's initial drilling operations are not
successful, the Company may redeploy its remaining capital budget to other
activities. See "Risk Factors - Substantial Capital Requirements."

ACCOUNTING POLICIES

      On October 23, 1995, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 123 ("FAS 123"), "Accounting for
Stock-Based Compensation," effective for the Company at December 31, 1996. Under
FAS 123 companies can either record expenses based on the fair value of
stock-based compensation upon issuance or elect to remain under the current "APB
Opinion No. 25" method, whereby no compensation cost is recognized upon grant,
and make disclosures as if FAS 123 had been applied. The Company will continue
to account for its stock-based compensation plans under APB Opinion No. 25.

                                       44
<PAGE>
      In January 1996, the Company adopted the provisions of the Financial
Accounting Standards Board Statement No. 121 ("FAS 121"), "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of."
FAS 121 requires the Company to review its oil and gas properties whenever
events or changes in circumstances indicate that the carrying amount of such
assets may not be recoverable, and recognize a loss if such recoverable amounts
are less than the carrying amount. There have been no impairment losses
recognized as of June 30, 1997, but any future losses would be included in
depletion, depreciation, amortization and impairment in future accounting
periods.

      In February 1997, the Financial Accounting Standards Board issued
Statement No. 128 ("FAS 128"), "Earnings Per Share", which simplifies the
computation of earnings per share. FAS 128 is effective for financial statements
issued for periods ending after December 15, 1997 and requires restatement for
all prior period earnings per share data presented. The Company is currently
complying with FAS 128.

      Also in early 1997, the Financial Accounting Standards Board issued
Statement No. 129 ("FAS 129"), "Disclosure of Information about Capital
Structure" effective for financial statements issued for periods ending after
December 15, 1997. The Company believes it is in compliance with the provisions
of this statement.

      In June 1997, the Financial Accounting Standard Board issued Statement No.
130 ("FAS 130"), "Reporting Comprehensive Income". FAS 130 establishes standards
for reporting and display of comprehensive income and its components in a full
set of general purpose financial statements. FAS 130 is effective for fiscal
years ending after December 15, 1997. The Company intends to comply with the
provisions of FAS 130.

                             BUSINESS AND PROPERTIES

      Callon Petroleum Company and its predecessors have been engaged in the
acquisition, development, exploration and production of oil and gas since 1950.
The Company's properties are geographically concentrated in Louisiana, Alabama
and offshore Gulf of Mexico. Callon also manages properties for certain
institutional investors. Callon was formed in 1994 through the consolidation of
a publicly traded limited partnership, a joint venture with a consortium of
European entities and an independent energy company owned by certain members of
current management. As of December 31, 1996, the Company had estimated net
proved reserves of 73.3 Bcfe with a PV-10 Value of $160.2 million, representing
increases of 26% and 151% respectively, from December 31, 1995.

      The Company's objective is to enhance stockholder value through sustained
growth in its reserve base, production levels and resulting cash flows from
operations. Over the past two and one-half years, the Company has increasingly
supplemented the acquisition of producing properties with the acquisition of
acreage with development and exploratory drilling opportunities to further
increase potential recoverable reserves. Since 1995, the Company has generated
47 prospects on 217,000 gross acres. In evaluating drilling opportunities,
Callon performs extensive geological and geophysical studies using CAEX,
including, where appropriate, the acquisition of 3-D seismic or high-resolution
2-D seismic data to facilitate these efforts.

EXPLORATION AND DEVELOPMENT OPERATIONS

      The Company's exploratory and development operations are concentrated in
three areas in the Gulf of Mexico: (i) the state waters of Alabama and the
federal outer continental shelf ("OCS") in the Gulf of Mexico where the Company
explores for shallow gas deposits ("Shallow Gas focus area"); (ii) the Breton
Sound area located primarily in the shallow state waters of Louisiana, where the
Company explores for hydrocarbon deposits at total well depths of between 8,000
to 14,000 feet ("Breton Sound focus area"); 

                                       45
<PAGE>
and (iii) other regions of the OCS, where the Company explores for hydrocarbon
deposits at total well depths of between 9,000 and 18,000 feet ("Deep OCS focus
area"). Wells drilled in the Shallow Gas focus area are characterized by
relatively low exploration and development costs, high initial production rates
and short reserve lives. Wells drilled in the Breton Sound focus area and Deep
OCS focus area are more expensive to drill and complete and have greater risks,
but seek larger oil and gas deposits with longer reserve lives.

      In 1995 and 1996, the Company acquired an extensive infrastructure of
production platforms, gathering systems and pipelines in its Shallow Gas focus
area and, during 1996, completed four proprietary high resolution 2-D seismic
surveys over an eight block area. Based on these surveys, in October and
November of 1996, the Company drilled two gross (1.52 net) successful
development wells and one gross (1.0 net) successful exploratory well in this
area. These wells were placed on production by the end of December 1996 and,
coupled with the replacement of compression equipment at the related production
facilities, the Company's average daily oil and gas production increased to 43.5
MMcfe/d during the first half of 1997, representing a 67% increase over 1996
average daily production rates. During the first six months of 1997, the Company
drilled one additional successful development well (1.0 net), one unsuccessful
development well for a net cost of $1.2 million, and performed one major
recompletion in its Shallow Gas focus area. Production from the new well
commenced in July 1997 and the recompletion is currently producing 6.3 MMcf/d
(3.6 MMcf/d net to the Company). The Company's capital budget for the last six
months of 1997 includes the drilling of five gross (2.7 net) exploratory wells
in its Shallow Gas focus area, for an aggregate net cost to drill and complete
of approximately $10.0 million.

      In its Breton Sound focus area, the Company owns and operates several old
prolific fields. In November 1996, the Company completed a 36 square-mile 3-D
seismic survey on its Main Pass 35 Field and adjoining acreage which resulted in
the identification of one development and seven exploratory drilling prospects.
Based upon this new data, the Company acquired an additional 5,170 gross acres,
which increased its holdings in the Breton Sound focus area to almost 10,000
gross acres. In July 1997, the Company entered into a joint venture agreement
with Burlington Resources Oil & Gas Company to drill these prospects. The
Company will operate these prospects and has retained an approximate 42.4%
working interest. In addition, the Company acquired a 100% working interest in a
development prospect on an adjacent block. The Company's capital budget for the
last six months of 1997 in the Breton Sound focus area includes the drilling of
two gross (1.45 net) development and one gross (0.45 net) exploratory wells for
an aggregate net cost to Callon to drill and complete of approximately $8.2
million.

      In 1996, the Company joined with Murphy Exploration and Production, Inc.
to acquire 18 federal blocks in the Deep OCS focus area and in 1997 joined with
Murphy and another oil company to acquire an additional 13 blocks, four of which
are located in the Shallow Gas focus area. The Company owns a 25% working
interest in 23 of these blocks and a 20% working interest in the remaining
eight. Murphy operates these properties. To date Callon has participated with
Murphy in the drilling of four gross (1.0 net) unsuccessful exploratory wells at
a total cost of $6.1 million, net to the Company. The Company's capital budget
for the last six months of 1997 includes the drilling of one gross (0.2 net)
Deep OCS focus area exploratory prospect at a net cost to Callon to drill and
complete of approximately $2.9 million.

      In total, the Company's current capital budget includes the drilling of
two gross (1.5 net) development wells and seven gross (3.3 net) exploratory
wells during the last six months of 1997 at an estimated net cost to the Company
to drill and complete of approximately $21.2 million. These drilling operations
will be financed from cash flows from operations, the net proceeds of the
offering of the Outstanding Notes and borrowings under the Company's Credit
Facility. See "Use of Proceeds."

PRODUCING PROPERTY ACQUISITIONS

      Over the past eight years, the Company has increased its reserves through
the acquisition of producing properties that are geologically complex, have (or
are analogous to fields with) an established production history from stacked pay
zones and are candidates for additional exploitation. The Company focuses on
reducing operating costs and implementing production enhancements through the
application of technologically advanced production and recompletion techniques.
Between 1989 and December 31, 1996, Callon acquired producing properties in 21
negotiated transactions, on behalf of itself and, in certain cases, its primary
institutional investor, for an aggregate net purchase price of approximately
$206 million and, during that period, the Company had an average Reserve
Replacement Cost of $0.84 per Mcfe.

ELF ACQUISITION

      In June 1997, the Company purchased from Elf Exploration, Inc. an 18.8%
working interest in the Mobile Area Block 864 Unit for approximately $11.8
million. The transaction also included Elf Exploration's 17.5% working interest
in Mobile Area Blocks 863 and 907 and a 35% working interest in Mobile Area
Block 908. The Mobile Area Block 864 Unit, operated by Chevron, is located in
the Company's Shallow Gas focus area about 12 miles south- southwest of the
Company's North Dauphin Island Field and is currently producing 26 MMcf/d
through the unit's facilities from sub-sea depths of 2,400 feet and 2,700 feet.
The Company believes exploratory drilling opportunities exist on the three
blocks. See the Company's MAB 864 Acquisition Financial Statements for further
information regarding the acquisition from Elf Exploration.

TECHNOLOGICAL EXPERTISE

      Through its acquisition program, the Company has assembled an operational
and technical database in certain geographical areas at a low cost to the
Company. The relationship with its institutional investors has allowed the
Company to pursue larger acquisitions, while the cost sharing arrangements and
ongoing management fees have enabled the Company to enhance the rate of return
on its properties and to maintain a larger, more experienced team of technical
and operating personnel than otherwise would be feasible for a company of its
size.

(1)   Future net cash flows attributable to the Company's estimated proved
      reserves and the present value of such cash flows were based on an average
      gas price of $3.88 per Mcf and an average oil price of $23.58 per Bbl at
      December 31, 1996. The average price received for production in 1996 was
      $2.63 per Mcf for gas and $20.55 per Bbl for oil, without the effects of
      hedging.

      MAIN PASS 163 AREA

      In two separate transactions during 1996, Callon acquired a 100% working
interest in Chandeleur Block 41 and Main Pass Blocks 159, 160, 161 and 163
located in its Shallow Gas focus area. The acquisition initially included five
wells producing 4 MMcf/d, as well as production facilities at Main Pass 163
capable of handling 90 MMcf/d.

      Based upon interpretation of seismic data acquired and processed by
Callon, an exploratory well was drilled on Main Pass Block 163 during the fourth
quarter of 1996. For the six months ending June 30, 1997, the well produced an
average of 13.5 MMcf/d. A development well was also drilled during the fourth
quarter of 1996 on Main Pass Block 161 and produced an average of 1.2 MMcf/d
during the first half of 1997. During the second quarter of 1997, the Company
drilled a successful well on Chandeleur Block 41 and production commenced in
July 1997. Total production from the Main Pass 163 Area averaged approximately
17.7 MMcf/d for the first six months in 1997.

      The Main Pass 163 Area wells produce from Shallow Miocene reservoirs at
approximate depths of 3,300 feet. Proved reserves at year-end 1996 attributable
to this area were 20.2 Bcf, representing 34.7% of the Company's total PV- 10
Value.

      CHANDELEUR BLOCK 40

      The Company and an institutional investor purchased a 33.3% working (27.8%
net revenue) interest in Chandeleur Block 40 in 1994 located in the Shallow Gas
focus area. On December 29, 1995, Callon acquired an additional 66.7% working
(55.5% net revenue) interest in the Chandeleur Block 40 for $9 million and
subsequently sold a 22.2% working interest in the field to an industry partner
for $3 million. The Company currently holds a combined 52.3% working (43.6% net
revenue) interest in this 

                                       48
<PAGE>
property. The field's remaining proved reserves are estimated to be 16.8 Bcf of
natural gas (net to the Company) as of December 31, 1996.

      When the Company assumed operations of the field, two wells were producing
5.5 MMcf/d of natural gas from the 3,800 foot sand. In February 1996, the
Company shut-in one well and successfully reworked the other and increased
average field production to 12 MMcf/d of natural gas.

      During the fourth quarter of 1996, the Company drilled a development well
in the field. For the six months ending June 30, 1997, the well was producing an
average of 21.5 MMcf/d. The well resulted in a field extension which added 6 Bcf
in estimated net proved reserves to the Company as of December 31, 1996. Total
field production averaged approximately 29.4 MMcf/d during the first half of
1997.

      BIG ESCAMBIA CREEK

      On June 29, 1995, the Company purchased an average working interest of
6.0% (6.6% net revenue interest), subject to a 10% reduction after payout, in
nine wells and a 2.9% average royalty interest in another six wells. The gross
average daily production for these wells during June 1997 was 3 MBbls of
condensate, 1.4 MBbls of natural gas liquids, 7.7 MMcf of residue natural gas
and 339 long tons of sulphur. These wells are producing from the Smackover
formation at depths ranging from 15,100 to 15,600 feet. Production in this field
has been partially curtailed due to low treatment plant capacity and, as a
result, no significant field production decline occurred during the past several
years.

      BLACK BAY COMPLEX

      The Company-operated Black Bay Complex (the "Complex") is located in
shallow waters off the Louisiana coast in the Breton Sound focus area. It
consists of eight fields, 90 producing wells and approximately 30,000 acres of
oil and gas leases, all of which are held by production. The Company owns an
average 15.4% working (11.6% net revenue) interest in the Complex and an
institutional investor, whose properties are managed by the Company, owns a
32.6% working interest. For the six months ending June 30, 1997, the Complex was
producing an average of 4,461 Bbls/d and cumulative production had reached 242
MMBbls of oil and 217 Bcf of natural gas.

      The discovery well in the Complex was completed in 1949. Forty-five
different sandstone formations and 137 separate reservoirs ranging in depth from
6,200 to 9,600 feet have been identified within the Complex. The Company assumed
operations of the Complex in August 1992, and since that time the Company has
successfully drilled seven development wells, including a horizontal well, and
implemented fourteen recompletions, seven of which employed a new stimulation
technology.

      NORTH DAUPHIN ISLAND FIELD

      The Company owns a 94.4% working (72.6% net revenue) interest in the North
Dauphin Island Field located in shallow Alabama state waters in the Company's
Shallow Gas focus area. The field was discovered in April 1990, and the wells
produce from a Shallow Miocene reservoir at approximately 1,800 feet. For the
six months ending June 30, 1997, there were three producing gas wells, two of
which were drilled horizontally, with average gross production of 6.7 MMcf per
day.

      The Company also owns a production platform, including compressors and
dehydration facilities, an associated gathering system and a 12-inch, 12-mile
pipeline ("North Dauphin Island Platform"). This pipeline runs to existing
onshore connections with the pipeline systems of Koch Gateway Pipeline Company,
Transcontinental Gas Pipe Line Corporation and Florida Gas Transmission Company.
The Company gathers its production and gas production from other producers
connected to its system, and delivers the gas to the major pipeline connections.
The current throughput capacity of the gathering

                                       49
<PAGE>
facility is in excess of 100 MMcf/d and with additional compression, the
throughput capacity can be increased to 130 MMcf/d. The ownership of the North
Dauphin Island Platform and associated pipeline provides the Company with a
significant strategic advantage in the North Dauphin Island area.

      In 1995, the Company signed an agreement with a subsidiary of a major oil
company providing for natural gas gathering services through the North Dauphin
Island Platform to onshore pipeline connections. The agreement further provides
for the subsidiary to purchase firm capacity commitments from the Company for
natural gas deliveries through the North Dauphin Island Platform for 15 years,
which commenced in April 1996, to gather up to 100 MMcf/d of the subsidiary's
natural gas production. Firm capacity reservations will average over $1.0
million per year through the term of the contract. Additional revenues may be
received depending upon the actual throughput used by the subsidiary.

EXPLORATION AND DEVELOPMENT PROJECTS

      Over the last two years, the Company shifted the focus of its operations
from the acquisition and exploitation of oil and gas properties to exploratory
and developmental drilling. The Company's exploration and development activity
is focused primarily in three areas in the Gulf of Mexico: the Shallow Gas focus
area, the Breton Sound focus area and the Company's Deep OCS focus area.

      SHALLOW GAS FOCUS AREA

      The Company's Shallow Gas focus area is located in the OCS offshore blocks
of Chandeleur, Main Pass and Viosca Knoll, as well as in the state waters of
Alabama. Wells drilled in the Shallow Gas focus area are characterized by
relatively low exploration and development costs, high initial production rates
and short reserve lives.

      The Company entered this area in 1993 with the purchase of North Dauphin
Island Field and has used state-of- the-art reservoir engineering and seismic
technology to develop proprietary processes which the Company believes provides
it with a competitive advantage in exploiting shallow (1,800 to 6,000 feet)
reservoirs.

      Through a series of acquisitions in 1995, 1996 and early 1997, Callon
acquired and now owns a concentrated leasehold position of 34,200 net acres in
eight contiguous blocks within its Shallow Gas focus area on which it has 10
producing wells. These blocks include Main Pass Blocks 159, 160, 161, 163, 164
and 165, and Chandeleur Blocks 40 and 41. Callon owns a 100% working interest in
five of the blocks and an average 61% working interest in the remaining three.
Callon now owns a 100% working interest in the production facilities at Main
Pass Block 163, a 52% interest in the production facilities at Chandeleur Block
40 and an approximate 66% interest in the production facilities at Main Pass
Block 165. This acreage position and infrastructure provide the potential for
increasing production, lowering operating costs and increasing reserves through
further drilling.

      During the third quarter of 1996, Callon completed the acquisition and
processing of more than 1,000 miles of seismic data over its eight blocks and
based upon interpretation of this data, identified eight potential drilling
locations.

      During October and November 1996, three Shallow Gas prospects were
successfully drilled and completed. The first prospect was drilled on Main Pass
Block 163 from a surface location adjacent to the Company's production facility
and encountered 54 feet of net pay in a new natural gas reservoir at a depth of
approximately 3,300 feet. During the first six months of 1997, the well averaged
13.5 MMcf/d. Callon has a 100% working (83% net revenue) interest in the well
which has added 11.2 MMcf/d net to production levels for the first half of 1997.

                                       50
<PAGE>
      At Chandeleur Block 40, the Company's #A-3 well encountered 44 feet of net
pay at a depth of approximately 3,855 feet. New compressor equipment was
installed on the Chandeleur Block 40 platform which enabled it to achieve
maximum production levels for the new well. The #A-3 well produced at an average
rate of 21.5 MMcf/d during the first six months of 1997, giving Chandeleur Block
40 average total natural gas production of 29.4 MMcf/d during such period. This
estimated 21.5 MMcf/d increase in production added 9.4 MMcf/d net to the
Company's 52.3% working (43.6% net revenue) interest.

      The third well was a sidetracked development well at Main Pass Block 161.
The well was drilled, completed and commenced production during February 1997
after compression facilities were upgraded. Callon has a 100% working (77.8% net
revenue) interest in the well which added 1.3 MMcf/d net to its existing
production.

      As a result primarily of the first two wells, Callon's average daily
production increased to 43.5 MMcfe/d during the first half of 1997, a 67%
increase from average 1996 production rates.

      During the first six months of 1997, the Company drilled one additional
successful development well (1.0 net), one unsuccessful development well for a
net cost of $1.2 million, and performed one major recompletion in its Shallow
Gas focus area. Production from the new well commenced in July 1997 and the
recompletion is currently producing 6.3 MMcf/d (3.6 MMcf/d net to the Company).
The Company's capital budget for the last six months of 1997 includes the
drilling of five gross (2.7 net) exploratory wells in its Shallow Gas focus
area, for an aggregate net cost to drill and complete of approximately $10.0
million. See "Risk Factors -- Substantial Capital Requirements."

      BRETON SOUND FOCUS AREA

      The Company's Breton Sound area is located in shallow state waters off the
Louisiana coast at the mouth of the Mississippi River. Callon owns interests in
and operates several large old prolific fields there. The fields have produced
from 165 separate reservoirs ranging in depth from 6,000 to 9,600 feet. The
Company's focus has been on the exploitation of the known producing horizons and
now is directed toward deeper potential prospects.

      The Black Bay Complex was discovered in 1949 and since that time has
produced 242 MMBbls of oil and 217 Bcf of natural gas from 45 sandstone
formations and 137 reservoirs. It consists of eight fields with 90 wells
producing 4,500 barrels of oil per day and 30,000 acres of oil and gas leases
held by production. Callon holds an average 15.4% working (11.6% net revenue)
interest in the Complex and manages a 32.6% working interest for an
institutional investor. Since assuming operations of the Complex in 1992, the
Company has substantially reduced operating costs, successfully drilled six
development wells, including one horizontally, and implemented 14 recompletions.
Callon has an inventory of over 32 identified development locations and
recompletion candidates at Black Bay and is evaluating the use of 3-D seismic to
identify additional reserves.

      Since its discovery in 1951, production from the Main Pass Block 35 Field,
located in Louisiana state waters, has totaled 66.5 MMBbls of oil and 76.5 Bcf
of natural gas from 28 reservoirs ranging in depth from 6,000 to 9,000 feet. In
November 1996, the Company received a new 36 square-mile 3-D seismic survey
covering its Main Pass 32/35 area. Callon identified eight prospects both under
and outside of its then existing 4,467 acre Main Pass 32 lease, based upon the
new seismic, and in December 1996, the Company acquired six contiguous tracts
covering an additional 5,170 acres at a total cost of $3.1 million. In July
1997, the Company entered into a joint venture agreement with Burlington
Resources Oil & Gas Company to drill these prospects. The Company will operate
these prospects and has retained an approximate 42.4% working interest.
Additionally, through a farmout agreement, the Company acquired a 100% working
interest in a development prospect on adjacent Main Pass Block 31. The Company's
capital budget in the last six months of 1997 in the Breton Sound focus area
includes the drilling of two 

                                       51
<PAGE>
(1.45 net) development and one gross (0.45 net) exploratory wells for an
aggregate net cost to Callon to drill and complete of approximately $8.2
million. See "Risk Factors -- Substantial Capital Requirements." The Company
anticipates drilling activities to begin in this area in the third quarter of
1997.

      DEEP OCS FOCUS AREA

      In addition to prospects in its Shallow Gas and Breton Sound focus areas,
the Company has developed an inventory of exploratory prospects in the Gulf of
Mexico OCS area where the Company explores for reserves at depths in excess of
10,000 feet. Wells drilled to these objectives are characterized by high risks,
higher drilling and completion costs and are subject to delays in commencing
sales of oil and gas, as production platforms and transportation facilities are
built. Targeted deposits of oil and gas in this focus area are significantly
larger than in the Shallow Gas focus area and have longer reserve lives.

      In April 1996, the Company entered into a joint bidding agreement with
Murphy Oil Corporation to acquire and develop oil and gas leases in federal
waters in the Gulf of Mexico where Murphy has operated successfully for many
years. The focus of the bidding agreement was participation in a diversified
group of high-quality 3-D seismic prospects with large reserve potential. At OCS
lease sale #157 in April 1996, Callon was the high bidder, with Murphy, on 13
federal offshore blocks and was awarded 12. The Company's successful bids
totaled $22.4 million encompassing 61,000 acres offshore Louisiana. The leases
are owned 25% by Callon and 75% by Murphy. The blocks include six in the West
Cameron South Addition, two in Mississippi Canyon and one block each in Eugene
Island, South Marsh Island, Vermilion and Main Pass East Addition.

      In September 1996, Callon again joined with Murphy and was high bidder on
six offshore Texas tracts at OCS lease sale #161. Callon participated in high
bids totaling $7.6 million for the six blocks, encompassing 35,000 acres. The
blocks include two in the High Island East Addition South Extension, one in the
High Island South Addition, and three in Garden Banks. The Company owns a 25%
working interest.

      In March 1997, Callon joined with Murphy and another oil company and were
high bidders on 14 blocks at OCS lease sale #166. All but one were awarded by
the MMS and Callon owns a 20% working interest in eight of the blocks and a 25%
working interest in five. The blocks cover 75,000 acres and are a mix of low,
moderate and high-risk prospects. Four of the blocks are in the Company's
Shallow Gas focus area and the balance are in the Deep OCS focus area. The
Company now owns a 25% interest in 23 blocks and a 20% interest in eight for a
total of 31 blocks.

      The Company's first four gross (1.0 net) exploratory wells drilled with
Murphy have been unsuccessful. The test well at West Cameron 603 was drilled to
a total depth of 15,200 feet and was abandoned. The Company is evaluating future
plans for the block. In February 1997, the Company drilled the first well at
Main Pass Block 247 which was plugged and abandoned. A second test well at Main
Pass 247 is scheduled for 1998. West Cameron 578/579 and Eugene Island 29 were
both dry and abandoned and a second well on Eugene Island 29 is scheduled for
1998. The Company's capital expenditure budget for the last six months of 1997
includes the drilling of one gross (0.25 net) exploratory well for a cost to
drill and complete of approximately $2.9 million.

(1)   Future net cash flows attributable to the Company's estimated proved
      reserves and the present value of such cash flows were based on an average
      gas price of $3.88 per Mcf and an average oil price of $23.58 per Bbl at
      December 31, 1996. The average price received for production in 1996 was
      $2.63 per Mcf for gas and $20.55 per Bbl for oil, without the effects of
      hedging.

      The Reserve Engineers prepared the estimates of proved reserves of the
Company and the future net cash flows (and present value thereof) attributable
to such proved reserves. Reserves were estimated using oil and gas prices and
production and development costs in effect on December 31 of each such year,
without escalation, and were otherwise prepared in accordance with the SEC
regulations regarding disclosure of oil and gas reserve information.

      There are numerous uncertainties inherent in estimating quantities of
proved reserves, including many factors beyond the control of the Company and
the Reserve Engineers. The reserve data set forth in this Prospectus represent
only estimates. Reserve engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
manner, and the accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment. As
a result, estimates by different engineers often vary, sometimes significantly.
In addition, physical factors, such as the results of drilling, testing and
production subsequent to the date of an estimate, as well as economic factors,
such as an increase or decrease in product prices that renders production of
such reserves more or less economic, may justify revision of such estimates.
Accordingly, reserve estimates are different from the quantities of oil and gas
that are ultimately recovered. See "Risk Factors -- Estimates of Oil and Gas
Reserves."

(1)   Drilling results prior to September 16, 1994 represent the combined
      drilling results of the Company's predecessors.

      The Company owned working and royalty interests in approximately 894 gross
(35.9 net) producing oil and 316 gross (21.2 net) producing gas wells as of
December 31, 1996. A well is categorized as an oil well or a gas well based upon
the ratio of oil to gas reserves on a Mcfe basis. However substantially all of
the Company's wells produce both oil and gas.

      As of December 31, 1996, the Company owned various royalty and overriding
royalty interests in 1,366 net developed acres and 6,953 undeveloped acres. In
addition, the Company owned 5,464 developed and 134,536 undeveloped mineral
acres.

MAJOR CUSTOMERS

      For the year ended December 31, 1996, Northridge Energy Marketing Company,
Williams Energy Services, Inc. and Sonat Gas Marketing Co. L.P. purchased 21%,
27% and 14%, respectively, of the Company's crude oil and natural gas
production. Northridge purchased crude oil production from the Black Bay
Complex, Williams Energy Services, Inc. purchased natural gas from the North
Dauphin Island Field, and Sonat Gas purchased natural gas from Callon owned
interests in federal OCS leases, Chandeleur Block 40, Main Pass 163 and Main
Pass 164/165. Because of the nature of oil and gas operations and the marketing
of production, the Company believes that the loss of these customers would not
have a material adverse impact on the Company's ability to sell its products.

TITLE TO PROPERTIES

      Callon believes that it has satisfactory title to the Company's oil and
gas properties in accordance with standards generally accepted in the oil and
gas industry, subject to the mortgages under the Credit Facility and such
exceptions which, in the opinion of the Company, are not so material as to
detract substantially from the use or value of such properties. In addition to
the mortgages, the Company's properties are typically subject, in one degree or
another, to one or more of the following: royalties and other burdens and
obligations, express or implied, under oil and gas leases; overriding royalties
and other burdens created by the Company or its predecessors in title; a variety
of contractual obligations (including, in some cases, development obligations)
arising under operating agreements, farmout agreements, production sales
contracts and other agreements that may affect the properties or their titles;
back-ins and reversionary interests arising under purchase agreements and
leasehold assignments; liens that arise in the normal course of operations, such
as those for unpaid taxes, statutory liens securing obligations to unpaid
suppliers and contractors and contractual liens under operating agreements;
pooling, unitization and communitization agreements, declarations and orders;
and easements, restrictions, rights-of-way and other matters that commonly
affect oil and gas producing property. To the extent that such burdens and
obligations affect the Company's rights to production revenues, they have been
taken into account in 

                                       55
<PAGE>
calculating the Company's net revenue interests and in estimating the size and
value of the Company's reserves. Callon believes that the burdens and
obligations affecting the Company's properties are conventional in the industry
for properties of the kind owned by the Company.

OTHER PROPERTIES

      The Company's headquarters are located in Natchez, Mississippi, in
approximately 51,500 square feet of owned space. The Company also maintains
field offices in the area of the major fields in which Callon operates
properties or has a significant interest, which are owned or leased.

EMPLOYEES

      The Company had 142 employees as of June 30, 1997, none of whom are
currently represented by a union. The Company considers itself to have good
relations with its employees. The Company employs ten petroleum engineers and
four petroleum geoscientists.

LITIGATION

      The Company is a defendant in various legal proceedings and claims which
arise in the ordinary course of Callon's business. Callon does not believe the
ultimate resolution of such actions will have a material effect on the Company's
financial position or results of operations.

COMPETITION, MARKETS AND REGULATIONS

      COMPETITION

      The oil and gas industry is highly competitive in all of its phases.
Callon encounters competition from other oil and gas companies in all areas of
the Company's operations, including the acquisition of reserves and producing
properties and the marketing of oil and gas. Many of these companies possess
greater financial and other resources than the Company. Competition for
producing properties is affected by the amount of funds available to the
Company, information about a producing property available to the Company and any
standards established by the Company for the minimum projected return on
investment. Because gathering systems and related facilities are the only
practical method for the intermediate transportation of gas, competition for gas
delivery is presented by other pipelines and gas gathering systems. Competition
may also be presented by alternate fuel sources.

      MARKETS

      Callon's ability to market oil and gas from the Company's wells depends
upon numerous factors beyond the Company's control, including the extent of
domestic production and imports of oil and gas, the proximity of the gas
production to gas pipelines, the availability of capacity in such pipelines, the
demand for oil and gas by utilities and other end users, the availability of
alternate fuel sources, the effects of inclement weather, state and federal
regulation of oil and gas production and federal regulation of gas sold or
transported in interstate commerce. No assurances can be given that Callon will
be able to market all of the oil or gas produced by the Company or that
favorable prices can be obtained for the oil and gas Callon produces.

      The supply of gas capable of being produced has exceeded demand in recent
years, as a result of decreased demand for gas in response to economic factors,
conservation, lower prices for alternate energy sources and other factors. As a
result of this excess supply of gas, gas producers have experienced increased
competitive pressure and lower prices. Substantially all of the gas produced by
the Company is sold at market responsive prices.

                                       56
<PAGE>
      In view of the many uncertainties affecting the supply of and demand for
oil, gas and refined petroleum products, the Company is unable to predict future
oil and gas prices and demand or the overall effect such prices and demand will
have on the Company. Callon does not believe that the loss of any of the
Company's oil purchasers would have a material adverse effect on the Company's
operations. Additionally, since substantially all of the Company's gas sales are
on the spot market, the loss of one or more gas purchasers should not materially
and adversely affect the Company's financial condition. The marketing of oil and
gas by Callon can be affected by a number of factors which are beyond the
Company's control, the exact effects of which cannot be accurately predicted.

      FEDERAL REGULATIONS

      SALES OF GAS. Effective January 1, 1993, the Natural Gas Wellhead
Decontrol Act deregulated prices for all "first sales" of gas. Thus, all sales
of gas by the Company may be made at market prices, subject to applicable
contract provisions.

      TRANSPORTATION OF GAS. The Company's sales of natural gas are affected by
the availability, terms and cost of transportation. The rates, terms and
conditions applicable to the interstate transportation of gas by pipelines are
regulated by the Federal Energy Regulatory Commission ("FERC") under the Natural
Gas Act ("NGA"), as well as under section 311 of the Natural Gas Policy Act
("NGPA"). Since 1985, the FERC has implemented regulations intended to increase
competition within the gas industry by making gas transportation more accessible
to gas buyers and sellers on an open-access, non-discriminatory basis.

      Most recently, in Order No. 636, et seq., the FERC promulgated an
extensive set of new regulations requiring all interstate pipelines to
"restructure" their services. The most significant provisions of Order No. 636
require that interstate pipelines provide firm and interruptible transportation
solely on an "unbundled" basis, separate from their sales service, and convert
each pipeline's bundled firm city-gate sales service into unbundled firm
transportation service and require that pipelines provide firm and interruptible
transportation service on a basis that is equal in quality for all gas supplies,
whether purchased from the pipeline or elsewhere. The order also recognized that
the elimination of city-gate sales service and the implementation of unbundled
transportation service would result in considerable costs being incurred by the
pipelines. Therefore, Order No. 636 provided mechanisms for the recovery by
pipelines from present, former and future customers of certain types of
"transition" costs likely to occur due to these new regulations.

      In subsequent orders, the FERC and the appellate court have substantially
upheld the requirements imposed by Order No. 636, although numerous court
appeals in which parties have sought review of separate FERC orders implementing
Order No. 636 on individual pipeline systems are still pending. In many
instances, the result of Order No. 636 and related initiatives has been to
substantially reduce or eliminate the interstate pipelines' traditional role as
wholesalers of natural gas in favor of providing only storage and transportation
services.

      The FERC has announced several important transportation-related policy
statements and proposed rule changes, including a statement of policy and
request for comments concerning alternatives to its traditional cost-of-service
ratemaking methodology to establish the rates interstate pipelines may charge
for their services. A number of pipelines have obtained FERC authorization to
charge negotiated rates as one such alternative. While the changes being
considered would affect the Company only indirectly, they are intended to
further enhance competition in natural gas markets. The Company cannot predict
what further action the FERC will take on these matters; however, the Company
does not believe that it will be affected by any action taken materially
differently than other natural gas producers.

                                       57
<PAGE>
      SALES AND TRANSPORTATION OF OIL. Sales of oil and condensate can be made
by the Company at market prices not subject at this time to price controls. The
price that the Company receives from the sale of these products will be affected
by the cost of transporting the products to market. As required by the Energy
Policy Act of 1992, the FERC has revised its regulations governing the rates
that may be charged by oil pipelines. The new rules, which were effective
January 1, 1995, provide a simplified, generally applicable method of regulating
such rates by use of an indexing system for setting transportation rate
ceilings. In certain circumstances, the new rules permit oil pipelines to
establish rates using traditional cost of service and other methods of rate
making. The effect that these new rules may have on the cost of moving the
Company's products to market cannot yet be determined.

      LEGISLATIVE PROPOSALS. In the past, Congress has been very active in the
area of gas regulation. There are legislative proposals pending in the state
legislatures of various states, which, if enacted, could significantly affect
the petroleum industry. At the present time it is impossible to predict what
proposals, if any, might actually be enacted by Congress or the various state
legislatures and what effect, if any, such proposals might have on the Company's
operations.

      FEDERAL, STATE OR INDIAN LEASES. In the event the Company conducts
operations on federal, state or Indian oil and gas leases, such operations must
comply with numerous regulatory restrictions, including various
nondiscrimination statutes, and certain of such operations must be conducted
pursuant to certain on-site security regulations and other appropriate permits
issued by the Bureau of Land Management ("BLM") or, in the case of the Company's
OCS leases in federal waters, Minerals Management Service ("MMS") or other
appropriate federal or state agencies. The Company's OCS leases in federal
waters are administered by the MMS and require compliance with detailed MMS
regulations and orders. The MMS has promulgated regulations implementing
restrictions on various production-related activities, including restricting the
flaring or venting of natural gas. In addition, the MMS has proposed to amend
its regulations to prohibit the flaring of liquid hydrocarbons and oil without
prior authorization. Under certain circumstances, the MMS may require any
Company operations on federal leases to be suspended or terminated. Any such
suspension or termination could materially and adversely affect the Company's
financial condition and operations. The MMS proposes to amend its regulations
governing the calculation of royalties and the valuation of crude oil produced
from federal leases. Among other matters, this proposed rule would amend the
valuation procedure for the sale of federal royalty oil. The Company cannot
predict what action the MMS will take on this matter, nor can it predict at this
stage of the proceeding how the Company might be affected by this proposed
amendment to the MMS' royalty regulations.

      The Mineral Leasing Act of 1920 (the "Mineral Act") prohibits direct or
indirect ownership of any interest in federal onshore oil and gas leases by a
foreign citizen of a country that denies "similar or like privileges" to
citizens of the United States. Such restrictions on citizens of a
"non-reciprocal" country include ownership or holding or controlling stock in a
corporation that holds a federal onshore oil and gas lease. If this restriction
is violated, the corporation's lease can be canceled in a proceeding instituted
by the United States Attorney General. Although the regulations of the BLM
(which administers the Mineral Act) provide for agency designations of
non-reciprocal countries, there are presently no such designations in effect.
The Company owns interests in numerous federal onshore oil and gas leases. It is
possible that the Common Stock will be acquired by citizens of foreign
countries, which at some time in the future might be determined to be
non-reciprocal under the Mineral Act.

      STATE REGULATIONS

      Most states regulate the production and sale of oil and gas, including
requirements for obtaining drilling permits, the method of developing new
fields, the spacing and operation of wells and the prevention of waste of oil
and gas resources. The rate of production may be regulated and the maximum

                                       58
<PAGE>
daily production allowable from both oil and gas wells may be established on a
market demand or conservation basis or both.

      The Company owns certain natural gas pipeline facilities that it believes
meet the traditional tests the FERC has used to establish a pipeline's status as
a gatherer not subject to FERC jurisdiction under the NGA. State regulation of
gathering facilities generally includes various safety, environmental, and in
some circumstances, nondiscriminatory take requirements, but does not generally
entail rate regulation. Natural gas gathering may receive greater regulatory
scrutiny at both state and federal levels in the post-Order No. 636 environment.

      The Company may enter into agreements relating to the construction or
operation of a pipeline system for the transportation of gas. To the extent that
such gas is produced, transported and consumed wholly within one state, such
operations may, in certain instances, be subject to the jurisdiction of such
state's administrative authority charged with the responsibility of regulating
intrastate pipelines. In such event, the rates which the Company could charge
for gas, the transportation of gas, and the construction and operation of such
pipeline would be subject to the rules and regulations governing such matters,
if any, of such administrative authority.

ENVIRONMENTAL REGULATIONS

      GENERAL. The Company's activities are subject to existing federal, state
and local laws and regulations governing environmental quality and pollution
control. Activities of the Company with respect to gas facilities, including the
operation and construction of pipelines, plants and other facilities for
transporting, processing, treating or storing gas and other products, are also
subject to stringent environmental regulation by state and federal authorities
including the Environmental Protection Agency ("EPA"). Risks are inherent in oil
and gas exploration and production operations, and no assurance can be given
that significant costs and liabilities will not be incurred in connection with
environmental compliance issues; nevertheless, the Company believes that, absent
the occurrence of an extraordinary event such as those noted under "Risk
Factors," compliance with existing federal, state and local laws, rules and
regulations regulating the release of materials into the environment or
otherwise relating to the protection of the environment will not have a material
adverse effect upon the capital expenditures, earnings or the competitive
position of the Company or its operations. The Company cannot predict what
effect future regulation or legislation, enforcement policies issued thereunder,
and claims for damages to property, employees, other persons and the environment
resulting from the Company's operations could have on its activities.

      SOLID AND HAZARDOUS WASTE. The Company currently owns or leases, and has
in the past owned or leased, numerous properties that for many years have been
used for the exploration and production of oil and gas. Although the Company
believes it has utilized operating and waste disposal practices that were
standard in the industry at the time, hydrocarbons or other solid wastes may
have been disposed or released on or under the properties owned or leased by the
Company or on or under locations where such wastes have been taken for disposal.
In addition, many of these properties have been owned or operated by third
parties. The Company had no control over such parties' treatment of hydrocarbons
or other solid wastes and the manner in which such substances may have been
disposed or released. State and federal laws applicable to oil and gas wastes
and properties have gradually become stricter over time. Under these new laws,
the Company could be required to remove or remediate previously disposed wastes
(including wastes disposed or released by prior owners or operators) or property
contamination (including groundwater contamination by prior owners or operators)
or to perform remedial plugging operations to prevent future contamination.

      The Company generates wastes, including hazardous wastes, that are subject
to the federal Resource Conservation and Recovery Act ("RCRA") and comparable
state statutes. The EPA and various 

                                       59
<PAGE>
state agencies have limited the approved methods of disposal for certain
hazardous and nonhazardous wastes. Furthermore, it is possible that certain
wastes generated by the Company's oil and gas operations that are currently
exempt from treatment as "hazardous wastes" may in the future be designated as
"hazardous wastes" under RCRA or other applicable statutes, and therefore be
subject to more rigorous and costly operating and disposal requirements.

      SUPERFUND. The Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA"), also known as the "Superfund" law, imposes liability,
without regard to fault or the legality of the original conduct, on certain
classes of persons with respect to the release of a "hazardous substance" into
the environment. These persons include the owner and operator of a disposal site
where a release occurred and any company that disposed or arranged for the
disposal of the hazardous substance released at the site. CERCLA also authorizes
the EPA and, in some cases, third parties, to take actions in response to
threats to the public health or the environment and to seek to recover from the
responsible classes of persons the costs of such action. In the course of its
operations, the Company has generated and will generate wastes that may fall
within CERCLA's definition of "hazardous substances." The Company may also be an
owner of sites on which "hazardous substances" have been released. The Company
may be responsible under CERCLA for all or part of the costs to clean up sites
at which such wastes have been disposed.

      OIL POLLUTION ACT. The Oil Pollution Act of 1990 (the "OPA") and
regulations thereunder impose a variety of regulations on "responsible parties"
related to the prevention of oil spills and liability for damages resulting from
such spills in United States waters. A "responsible party" includes the owner or
operator of an onshore facility, vessel or pipeline, or the lessee or permittee
of the area in which an offshore facility is located. The OPA assigns liability
to each responsible party for oil removal costs and a variety of public and
private damages. While liability limits apply in some circumstances, a party
cannot take advantage of liability limits if the spill was caused by gross
negligence or willful misconduct or resulted from violation of a federal safety,
construction or operating regulation. If the party fails to report a spill or to
cooperate fully in the cleanup, liability limits also do not apply. Few defenses
exist to the liability imposed by the OPA. The failure to comply with OPA
requirements may subject a responsible party to civil or even criminal
liability.

      The OPA also imposes ongoing requirements on a responsible party,
including proof of financial responsibility to cover at least some costs in a
potential spill. Certain amendments to the OPA that were enacted in 1996 require
owners and operators of offshore facilities that have a worst case oil spill
potential of more than 1,000 barrels to demonstrate financial responsibility in
amounts ranging from $10 million in specified state waters to $35 million in
federal OCS waters, with higher amounts, up to $150 million in certain limited
circumstances, where the MMS believes such a level is justified by the risks
posed by the quantity or quality of oil that is handled by the facility. On
March 25, 1997, the MMS promulgated a proposed rule implementing these OPA
financial responsibility requirements. The Company believes that it currently
has established adequate proof of financial responsibility for its offshore
facilities. However, the Company cannot predict whether the financial
responsibility requirements under the OPA amendments or the proposed rule will
result in the imposition of substantial additional annual costs to the Company
in the future or otherwise materially adversely affect the Company. The impact
of the financial responsibility requirements is not expected to be any more
burdensome to the Company than it will be to other similarly or less capitalized
owners or operators in the Gulf of Mexico.

      PROHIBITION ON DISCHARGES OF PRODUCED WATER. In connection with its
offshore exploration and production operations offshore Louisiana, the Company
is subject to a state-wide prohibition, effective July 1, 1997, against the
discharge of produced water into state coastal waters. However, the Company has
received an extension of time for complying with this prohibition until
September 30, 1998 for its facilities at Chandeleur Block 25 and Main Pass Block
35, and until October 31, 1998 for its facilities at 

                                       60

Black Bay Complex. The Company believes that it will be in compliance with the
prohibition prior to expiration of the applicable deadlines.

      AIR EMISSIONS. The operations of the Company are subject to local, state
and federal laws and regulations for the control of emissions from sources of
air pollution. Administrative enforcement actions for failure to comply strictly
with air regulations or permits may result in the payment of civil penalties
and, in extreme cases, the shutdown of air emission sources.

      OSHA AND OTHER REGULATIONS. The Company is subject to the requirements of
the federal Occupational Safety and Health Act ("OSHA") and comparable state
statutes. The OSHA hazard communication standard, the EPA community
right-to-know regulations under Title III of CERCLA and similar state statutes
require the Company to organize and/or disclose information about hazardous
materials used or produced in the Company's operations. The Company believes
that it is in substantial compliance with these applicable requirements.

      EMPLOYMENT AGREEMENTS, TERMINATION OF EMPLOYMENT AND CHANGE-IN-CONTROL
      ARRANGEMENTS

      Fred L. Callon entered into an employment agreement with the Company
effective September 1, 1996 with a term ending December 31, 2000. Pursuant to
this agreement, Fred L. Callon will receive an annual base salary of not less
than $200,000 per annum, subject to increase by the Board of Directors or
Compensation Committee from time to time. The employment agreement provides that
he will be entitled to participate in any incentive compensation program
established by the Company for its executive officers. Fred L. Callon also will
receive life insurance, participate in the group medical and disability
insurance of the Company and receive a monthly automobile allowance under the
agreement as well as fuel, oil, maintenance and insurance costs for an
automobile. The agreement will be terminated prior to its term by his death or
disability or for cause. If the agreement is terminated because of death or
disability, the compensation payments continue for the term of the agreement,
reduced by the amount of disability insurance paid. If the agreement is
terminated for cause, the Company is not required to make additional payments.
"Cause" is defined generally as any of the following, as determined by a
majority vote of the Board of Directors: intentional or continual neglect of
duties, conviction of a felony, or failure or refusal to perform duties in
accordance with the employment agreement.

      The employment agreement further provides that he may terminate the
agreement for "good reason," which is defined generally as (a) failure to
re-elect him to his office, (b) significant change in his duties, (c) reduction
or failure to provide typical increases in his salary following a change in
control of the Company, (d) his relocation to an office outside the Natchez,
Mississippi area, (e) breach of the agreement by the Company, or (f) failure to
maintain his level of participation in the compensation and benefit plans of the
Company. If Fred L. Callon terminates his employment for good reason after a
change in control, he is entitled to a lump sum payment of three times his
targeted annual compensation for that year. The lump sum payment will be reduced
to the maximum amount permitted under the Internal Revenue Code of 1986, as
amended (the "Code"), that does not constitute a parachute payment unless he
elects to receive the full amount, in which case the Company would be liable for
the resulting federal excise tax. The Code defines a parachute payment as any
severance payment the aggregate present value 

                                       66
<PAGE>
of which is in excess of three times the employee's average annual compensation
over the past five years. If the termination for good reason occurs otherwise
than following a change in control, he is entitled to severance pay in the
amount that would have been paid under the employment agreement had it not been
terminated. Pursuant to the agreement, a "change in control" occurs, if: (i) any
person or group of persons acting in concert (within the meaning of Section
13(d) of the Exchange Act) shall have become the beneficial owner of a majority
of the outstanding common stock of the Company (other than pursuant to the
Stockholders' Agreement), (ii) the stockholders of the Company cause a change in
a majority of the members of the board within a twelve-month period, or (iii)
the Company or its stockholders enter into an agreement to dispose of all or
substantially all of the assets or outstanding capital stock of the Company.

      Dennis W. Christian and John S. Weatherly entered into employment
agreements with the Company effective September 1, 1996 and ending December 31,
2000. The agreements provide that Mr. Christian and Mr. Weatherly will receive
an annual base salary of at least $175,000 and $165,000, respectively, and that
they are entitled to participate in any incentive compensation program
established by the Company for its executive officers. Each agreement terminates
upon death or disability or for cause. If either agreement is terminated because
of death or disability, compensation payments continue for a period of two years
from the date of termination, reduced by the amount of disability insurance
paid. If either agreement is terminated for cause, the Company is not required
to make any additional payments. "Cause" is defined generally as any of the
following, as determined by a majority vote of the Board of Directors:
intentional or continual neglect of duties, conviction of a felony, or failure
or refusal to perform duties in accordance with the employment agreement.

      On June 19, 1996, the Company entered into a consulting agreement with
John S. Callon which became effective January 2, 1997, the day he retired as
Chief Executive Officer of the Company. Pursuant to the agreement, John S.
Callon is to provide consulting services to the Company on matters pertaining to
corporate or financial strategy, investor relations and public/private financing
opportunities for no more than 20 hours per month, ten months a year. The
agreement remains in effect from the effective date until December 31, 2001,
subject to renewal for succeeding five years periods unless earlier terminated.
As compensation for his services under the agreement, John S. Callon will be
paid a fee ("Consultation Fee") of not less than $190,000 per year increased
annually based upon the change in the Consumer Price Index, as adjusted for
inflation. In addition, he will remain eligible to participate in the Company's
major medical and disability coverage, and will be entitled to participate in
all other employee benefit plans (other than a cash bonus program) provided to
full-time executives of the Company. As an inducement for entering into the
agreement, John S. Callon was granted 25,000 shares of Common Stock, 20% of
which vests on each of the first five anniversaries of the effective date of the
agreement.

      Upon termination of the agreement other than for cause, John S. Callon or
his spouse shall be entitled to receive a termination payment equal to the
Consultation Fee, as adjusted for inflation, to be paid annually until the later
of the death of John S. Callon (if applicable) or his spouse. In lieu of the
termination payment, John S. Callon or his spouse may elect to receive, subject
to the approval of the Board of Directors a lump sum payment of $1.5 million. In
addition, if the agreement terminates due to the Company's breach, John S.
Callon and his spouse shall be entitled to liquidated damages. The Company may
terminate the agreement for cause. "Cause" is defined generally in the agreement
as willful misconduct or intentional and continual neglect of duties which has
materially and adversely affected the Company.

      Pursuant to the 1996 Plan and the 1994 Plan (as defined below), in the
case of a merger or consolidation where the Company is not the surviving entity,
or if the Company is about to sell or otherwise dispose of substantially all of
its assets while unvested options remain outstanding, the Compensation Committee
or other plan administrator may, in its discretion and without stockholder
approval, declare some or all options exercisable in full before or
simultaneously with such merger, consolidation or sale of assets without regard
for prescribed waiting periods. Alternatively, the

                                       67
<PAGE>
Compensation Committee or other plan administrator may cancel all outstanding
options provided option holders are given notice and a period of 30 days prior
to the merger, consolidation or sale to exercise the options in full.

      INCENTIVE PLANS

      The Company currently maintains two stock options plans for employees
pursuant to which options may be granted for the purchase of Common Stock: the
1994 Callon Petroleum Company Stock Incentive Plan (the "1994 Plan") and the
1996 Callon Petroleum Company Stock Incentive Plan (the "1996 Plan"). The
Company in the past has used and will continue to use, stock options and
performance share grants to attract and retain key employees in the belief that
employee stock ownership and stock related compensation devices encourage a
community of interest between employees and stockholders. No additional awards
may be granted under the 1994 Plan. As of June 30, 1997, there were 145,000
shares available for grant under the 1996 Plan.

      1994 PLAN. The 1994 Plan was adopted on June 30, 1994. Pursuant to the
1994 Plan, 600,000 shares of Common Stock were reserved for issuance upon the
exercise of options or as performance shares. The 1994 Plan is administered by
the Compensation Committee of the Board of Directors. Members of the
Compensation Committee currently are Messrs. Stanger, Wallace, B. F. Weatherly
and Wilson.

      No stock options were granted under the 1994 Plan during 1995 and 1996,
other than automatic grants to non-employee directors.

      1996 PLAN. On September 26, 1996, the Board of Directors of the Company
approved and adopted the 1996 Plan and the Plan was approved by the stockholders
of the Company at the 1997 annual meeting. Individual awards under the 1996 Plan
may take the form of one or more of (i) incentive stock options; (ii)
non-qualified stock options; or (iii) performance shares.

      The 1996 Plan is administered by a plan administrator which may be either
(i) the Board of Directors of the Company; (ii) any duly constituted committee
of the Board of Directors consisting of at least two non-employee directors; or
(iii) any other duly constituted committee of the Board of Directors. The plan
administrator will select the officers, key employees and consultants who will
receive awards and the terms and conditions of those awards. The maximum number
of shares of Common Stock that may be subject to outstanding awards may not
exceed 300,000. Shares of Common Stock tendered as payment for shares issued
upon exercise of an option or which are attributable to awards which have
expired, terminated or been canceled or forfeited are available for issuance or
use in connection with future awards.

      The option price of any incentive stock option shall be 100% of the fair
market value of a share of Common Stock on the date the incentive option is
granted. Any incentive option must be exercised within ten years of the date of
grant. Unless otherwise determined by the plan administrator, the option price
of any non-qualified stock option shall be 100% of the fair market value of a
share of Common Stock on the date the option is granted. Vesting of stock
options and performance shares, and the term of any non-qualified stock option
or performance share award is determined by the plan administrator.

      The 1996 Plan provides that each director that is not an employee of the
Company shall, on the date on which he or she is initially elected or appointed
a director of the Company, be granted a stock option to purchase 5,000 shares of
Common Stock for the fair market price on the date of grant and for a term of
ten years. After each subsequent annual meeting of stockholders at which such
person continues to serve as a director, he or she will automatically be granted
a stock option to purchase an additional 5,000 shares of Common Stock for the
fair market price on the date of such grant and for a term of ten years.

                                       68
<PAGE>
      In the event of a termination of employment, outstanding options and
performance shares may be subject to forfeiture and/or time limitations. Stock
options and performance shares are evidenced by written agreements, the terms
and provisions of which may differ. No stock option is transferable other than
by will or by the laws of descent or distribution.

      The 1996 Plan may be amended by the Board of Directors without the consent
of the stockholders except that any amendment, thought effective when made, will
be subject to stockholder approval if required by any federal or state law or
regulation or by the rules of any stock exchange or automated quotation system
on which the Common Stock may then be listed or quoted. In addition, no
amendment can impair the rights of a holder of an outstanding award under the
Plan without such holder's consent.

      1997 EMPLOYEE STOCK PURCHASE PLAN. The 1997 Employee Stock Purchase Plan
(the "1997 Purchase Plan") was authorized by the Board of Directors on September
26, 1996 and approved by the stockholders of the Company at the 1997 annual
meeting. The 1997 Purchase Plan is intended to provide eligible employees of the
Company and its participating affiliates with the continuing opportunity to
acquire a propriety interest in the Company through participation in a
payroll-deduction based employee stock purchase plan designed to operate in
compliance with Section 423 of the Code.

      An aggregate of 250,000 shares of Common Stock have been reserved for
issuance over the ten-year term of the 1997 Purchase Plan. This share reserve is
drawn from either newly-issued shares of Common Stock or shares of Common Stock
repurchased by the Company, including shares repurchased on the open market.

      The 1997 Purchase Plan is administered by the Compensation Committee of
the Company's Board of Directors or such other duly constituted committee of the
Company's Board of Directors (the "1997 Plan Administrator"). The 1997 Purchase
Plan is implemented in a series of successive offering periods, each with a
maximum duration (not to exceed twenty-four (24) months) designated by the 1997
Plan Administrator prior to the start date. The initial offering period began on
September 1, 1997 and will continues through June 30, 1999. The next offering
period will start on the first business day in July 1999 and terminate on the
last business day in June 2001. Any subsequent offering periods will begin as
designated by the 1997 Plan Administrator.

      Each offering period is comprised of a series of successive semi-annual
purchase periods. Generally, purchase periods run from the first business day in
January to the last business day in June each year and from the first business
day in July each year to the last business day in December in each year. Shares
of Common Stock will be purchased on behalf of participants on the last day of
each such semi-annual period.

      Any individual who is employed on a basis under which he or she is
regularly expected to work for more than 20 hours per week for more than five
months per calendar year in the employ of the Company or any participating
parent or subsidiary corporation (including any corporation which subsequently
becomes such at any time during the term of the 1997 Purchase Plan) is eligible
to participate in the 1997 Purchase Plan.

      Each participant may authorize periodic payroll deductions in any multiple
of 1% (up to a maximum of 15%) of his or her base salary each offering period to
be applied to the acquisition of Common Stock on each semi-annual purchase date.
On each semi-annual purchase date (the last business day in June and December of
each year), the payroll deductions of each participant is automatically applied
to the purchase of whole shares of Common Stock at the purchase price in effect
for the participant for that purchase date.

                                       69
<PAGE>
      The purchase price per share at which Common Stock is purchased on the
participant's behalf on each purchase date within the offering period is equal
to eighty-five percent (85%) of the lower of (i) the fair market value per share
of Common Stock on the participant's entry date into that offering period or
(ii) the fair market value per share of Common Stock on that purchase date. The
fair market value per share of Common Stock on any relevant date will be the
closing selling price per share on such date on the Nasdaq NMS.

      The 1997 Purchase Plan imposes certain limitations upon a participant's
rights to acquire Common Stock, including the following limiations:

            (i) No purchase right may be granted to any individual who owns
      stock (including stock purchasable under any outstanding purchase rights)
      possessing 5% or more of the total combined voting power or value of all
      classes of stock of the Company of any of its affiliates.

            (ii) No purchase right granted to a participant may permit such
      individual to purchase Common Stock at a rate greater than $25,000 worth
      of such Common Stock (valued at the time such purchase right is granted)
      for each calendar year the purchase right remains outstanding at any time.

            (iii) No participant may purchase more than 1,000 shares of Common
      Stock on any semi-annual purchase date.

      The purchase right immediately terminates upon the participant's
termination of employment or loss of eligible employee status or upon his or her
affirmative withdrawal from the offering period. The payroll deductions
collected for the purchase period in which the purchase right terminates will be
refunded.

      No participant has any stockholder rights with respect to the shares of
Common Stock covered by his or her purchase right until the shares are actually
purchased on the participant's behalf.

      The 1997 Purchase Plan terminates upon the earliest to occur of (i) the
last business day in June 2007, (ii) the date on which all available shares are
issued or (iii) the date on which all outstanding purchase rights are exercised
in connection with an acquisition of the Company.

      The Board may at any time alter, suspend or discontinue the 1997 Purchase
Plan as of the close of any purchase period. However, the Board may not, without
stockholder approval, materially increase the number of shares issuable under
the 1997 Purchase Plan, and certain other amendments may require stockholder
approval pursuant to applicable laws or regulations.

      Common Stock at the date of grant was $12.00. Options are not exercisable
      prior to six months from the date of grant and, unless a shorter period is
      provided by the 1996 Plan or the plan administrator, are for a term of ten
      years, subject to vesting as provided by the plan administrator. Further,
      options are subject to forfeiture and/or time limitations in the event of
      a termination of employment. The 1996 Plan was approved by the Company's
      stockholders at the 1997 annual meeting. No stock appreciation rights have

      provided in accordance with rules of the Commission and do not represent
      the Company's estimate or projection of the future Common Stock price.
      Actual gains, if any, on stock option exercises are dependent on the

transaction which would result in certain changes of control or fundamental
changes without the prior written consent of the other party. The Callon Family
and NOCO own an aggregate of more than 60% of the Company's outstanding Common
Stock.

      REGISTRATION RIGHTS. The Callon Family (including John S. Callon and Fred
L. Callon) is party to a Registration Rights Agreement dated September 16, 1994
(the "Registration Rights Agreement"), pursuant to which they are entitled to
require the Company to register Common Stock owned by them with the Commission
for sale to the public in a firm commitment public offering and generally to
include shares owned by them in registration statements filed by the Company.
NOCO and the Company have entered into a similar agreement.

      WILCOX ENERGY. Prior to the consummation of the Consolidation, Callon
Petroleum Operating distributed the capital stock of its wholly owned
subsidiary, Wilcox Energy Company ("Wilcox"), to its stockholders (i.e., the
Callon Family, including John S. Callon and Fred L. Callon). The business of
Wilcox is the drilling of shallow exploratory wells in the Wilcox Trend, and
Callon Petroleum Operating did not believe that Wilcox would fit within the
Company's business strategy.

      NOTE TO AFFILIATE. Prior to the Consolidation, CN from time to time loaned
money to NOCO on a short-term basis, at approximately the interest rate earned
by CN on short-term cash investments. In 1993, $4.0 million was borrowed. On
December 31, 1993, $1.0 million was outstanding at an interest rate of 4.0%. In
1994, the outstanding loan balance of $1.0 million was repaid prior to the
Consolidation.

      FEES TO NOCO. Prior to the Consolidation, the partnership agreement of CN
provided that CN would reimburse Callon Petroleum Operating and NOCO at cost for
overhead and executive and other personnel services for operations of CN. During
1993, CN paid Callon Petroleum Operating $1.4 million and paid NOCO $320,000 as
such reimbursement. NOCO Management, Ltd., the general partner of NOCO Holdings,
L.P. (the sole limited partner of NOCO) and whose members include John C.
Wallace, Richard O. Wilson and B. F. Weatherly, directors of the Company,
received $190,200 in 1993 of such amounts in fees for services provided to CN by
its members, including Mr. Wallace and B.F. Weatherly. In turn, Mr. Wallace
received $13,500 of such amounts in 1993, and B.F. Weatherly received $67,500 of
such amounts in 1993 from NOCO Management, Ltd. for such services. In 1994, the
Company reimbursed NOCO $131,000 for costs and expenses incurred by NOCO in the
Consolidation. No overhead payments have been made following the effective date
of the Consolidation.

      interests in NOCO and NOCO Holdings, L.P. As a result of their positions
      with NOCO Management, Ltd., Messrs. Wallace, Meade, Weatherly and Wilson
      may be deemed to share the power to vote and dispose of such Common Stock

      terms of the Stockholders' Agreement, NOCO has the right of first refusal
      to acquire shares of Common Stock proposed to be sold by members of the
      Callon Family under certain circumstances and all parties to the
      Stockholders' Agreement have agreed to support two directors nominated by
      the Callon Family and two directors nominated by NOCO. NOCO disclaims
      beneficial ownership of the shares owned by members of the Callon Family.
      Because of the Stockholders' Agreement, NOCO and members of the Callon
      Family may be deemed to be a "group" for purposes of beneficial ownership
      under SEC regulations. If such a group were deemed to exist, it would
      beneficially own over 60% of the Common Stock. NOCO has informed the
      Company that it intends to transfer 1,839,386 of the Common Shares owned
      by it to Fred. Olsen Energy AS ("FOE"). Upon such transfer, the Common
      Shares owned by FOE will continue to be subject to the Stockholders'
      Agreement. See "Principal Stockholders -- Stockholders' Agreement."

(13)  Includes 563,000 shares issuable upon conversion of 247,690 shares of
      Series A Preferred Stock.

STOCKHOLDERS' AGREEMENT

      Pursuant to the Stockholders' Agreement among the Callon Family and NOCO
dated September 16, 1994, the Callon Family and NOCO each elect two directors to
the Company's Board of Directors. Specifically, the Stockholders' Agreement
provides that the Callon Family and NOCO shall use their best efforts, including
voting the shares of Common Stock which they own, to cause the Company's Board
of Directors to be composed of at least four members, two of such members to be
selected by the Callon Family and two of such members to be selected by NOCO.
The Stockholders' Agreement also contains restrictions on transfer of shares of
Common Stock owned by the Callon Family and NOCO and prohibits the Callon Family
and NOCO from taking certain actions which would result in certain changes of
control or fundamental changes, without the consent of the other party. See
"Management -- Certain Transactions."

      As a result of the Stockholders' Agreement, the Callon Family, on the one
hand, and the Callon Family and NOCO on the other, may be deemed to form a
"group" for purposes of beneficial ownership under Commission regulations. The
Callon Family disclaims beneficial ownership of the Common Stock owned by NOCO.
In addition, each Callon Family stockholder disclaims beneficial ownership of
all shares of Common Stock owned by the other Callon Family stockholders and the
existence of a group comprised of the Callon Family stockholders. If NOCO and
the Callon Family were deemed to be a group, it would beneficially own more than
60% of the outstanding Common Stock.

                        DESCRIPTION OF THE EXCHANGE NOTES

      The Exchange Notes are to be issued under the Indenture, dated as of July
31, 1997, between the Company and American Stock Transfer & Trust Company, as
trustee (the "Trustee"). The Exchange Notes will be issued under the same
Indenture as the Outstanding Notes and the Outstanding Notes and the Exchange
Notes will constitute a single series of debt securities under the Indenture. If
the Exchange Offer is consummated, any Outstanding Notes that remain outstanding
after consummation of the Exchange Offer and the Exchange Notes issued in the
Exchange Offer will vote together as a single class for purposes of determining
whether holders of the requisite percentage in outstanding principal of Notes
(as defined herein) have taken certain actions or exercised certain rights under
the Indenture.

     The following summary of certain provisions of the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the provisions of the Indenture (including the definition of
certain terms in the Indenture), the form of which is available upon request to
the Company at the address set forth under "Available Information." Wherever
particular provisions and definitions of the Indenture are referred to, such
provisions and definitions are incorporated by reference as part of the
statements made, and the statements are qualified in their entirety by such
reference. As used in this "Description of the Exchange Notes," the term
"Company" refers only to Callon Petroleum Company. The Outstanding Notes and
Exchange Notes are sometimes referred to herein as the "Notes." Article and
Section references are to Articles and Sections of the Indenture.

      GENERAL. The Exchange Notes will be limited to $36.0 million aggregate
principal amount. The Exchange Notes will be issued in global or registered form
only, without coupons, in denominations of $1,000 and any integral multiple
thereof. Interest on the Exchange Notes will accrue from July 31, 1997 or from
the most recent interest payment date to which interest has been paid, and will
be payable quarterly on the 15th day of each March, June, September and December
in each year, commencing December 15, 1997, at 10.125%. Interest will be payable
to the person in whose name the Exchange Note is registered at the close of
business on the first day of March, June, September and December, as the case
may be, immediately preceding such interest payment date. The Exchange Notes
will mature on September 15, 2002, unless redeemed earlier at the option of the
Company as set forth below. The Company is not required to make mandatory
redemption or sinking fund payments with respect to the Exchange Notes.

      Principal, premium, if any, and interest will be payable at an office or
agency to be maintained by the Company in New York City, except that, at the
option of the Company for the Exchange Notes that are not in book entry form,
interest may be paid by check mailed to the person entitled thereto. The
Exchange Notes may be presented for registration of transfer or exchange at an
office or agency to be maintained by the Company in New York City. The Exchange
Notes will be exchangeable without service charge but the Company may require
payment to cover taxes or other government charges. Except under the conditions
described in "Certain Covenants -- Liens" below, the Exchange Notes will not
be secured by the assets of the Company or any of its Subsidiaries or Affiliates
or otherwise. All indebtedness of the Company under the Credit Facility (which
constitutes Senior Indebtedness) is secured by substantially all of the
producing oil and gas assets of the Company and its Subsidiaries. In addition,
the rights of the Company to participate in any distribution of assets of any
Subsidiary upon its liquidation or reorganization or otherwise (and thus the
ability of the Holders of the Exchange Notes to benefit indirectly from such
distribution) are subject to the prior claims of creditors of the Subsidiary.

      BOOK ENTRY EXCHANGE NOTES

      The Outstanding Notes have been and the Exchange Notes will initially be
issued in the form of one or more Global Exchange Notes (as defined in the
Indenture) held in book-entry form. The Exchange Notes will be deposited with
the Trustee as custodian for the Depository, and the Depository or its nominee
will initially be the sole registered holder of the Exchange Notes for all
purposes under the 

                                       77
<PAGE>
Indenture. Except as set forth below, a Global Exchange Note exchanged may not
be transferred except as a whole by the Depository to a nominee of the
Depository or by a nominee of the Depository to the Depository.

      Upon the issuance of a Global Exchange Note, the Depository or its nominee
will credit, on its internal system, the accounts of persons holding through it
with the respective principal amounts of the individual beneficial interests
represented by such Global Exchange Note exchanged in the Exchange Offer.
Ownership of beneficial interests in a Global Exchange Note will be limited to
persons that have accounts with the Depository ("participants") or persons that
may hold interests through participants. Ownership of beneficial interests by
participants in a Global Exchange Note will be shown on, and the transfer of
that ownership interest will be effected only through, records maintained by the
Depository or its nominee for such Global Exchange Note. Ownership of beneficial
interests in such Global Exchange Note by persons that hold through participants
will be shown on, and the transfer of that ownership interest within such
participant will be effected only through, records maintained by such
participant. The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to transfer beneficial interests in
a Global Exchange Note.

      Payment of principal of, premium, if any, on and interest on Exchange
Notes represented by any such Global Exchange Note will be made to the
Depository or its nominee, as the case may be, as the sole registered owner and
the sole holder of the Exchange Notes represented thereby for all purposes under
the Indenture. None of the Company, the Trustee, and agent of the Company or the
Initial Purchaser will have any responsibility or liability for any aspect of
the Depository's reports relating to or payments made on account of beneficial
ownership interests in a Global Exchange Note representing any Exchange Notes or
for maintaining, supervising or reviewing any of the Depository's records
relating to such beneficial ownership interests.

      The Company has been advised by the Depository that upon receipt of any
payment of principal of, premium, if any, on or interest on, any Global Exchange
Note, the Depository will immediately credit, on its book entry registration and
transfer system, the accounts of participants with payments in amounts
proportionate to their respective beneficial interests in the principal or face
amount of such Global Exchange Note, as shown on the records of the Depository.
The Company expects that payments by participants to owners of beneficial
interests in a Global Exchange Note held through such participants will be
governed by standing instructions and customary practices as is now the case
with securities held for customer accounts registered in "street name" and will
be the sole responsibility of such participants.

      So long as the Depository or its nominee, is the registered owner or
holder of such Global Exchange Note, the Depository or such nominee, as the case
may be, will be considered the sole owner or holder of the Exchange Notes
represented by such Global Exchange Note for the purposes of receiving payment
on such Exchange Notes, receiving notices and for all other purposes under the
Indenture and the Exchange Notes. Beneficial interests in the Exchange Notes
represented by such Global Exchange Note will be evidenced only by, and
transfers thereof will be effected only through, records maintained by the
Depository and its participants. Except as provided above, owners of beneficial
interests in a Global Exchange Note will not be entitled to and will not be
considered the holders of such Global Exchange Note for any purposes under the
Indenture. Accordingly, each person owning a beneficial interest in a Global
Exchange Note must rely on the procedures of the Depository and, if such person
is not a participant, on the procedures of the participant through which such
person owns its interest, to exercise any rights of a holder under the
Indenture. The Company understands that under existing industry practices, in
the event that the Company requests any action of holders or that an owner of a
beneficial interest in a Global Exchange Note desires to give or take action
that a holder is entitled to give or take under the Indenture, the Depository
would authorize the participants holding the relevant beneficial interest to
give or take such action, and such participants would authorize beneficial
owners through such 

                                       78
<PAGE>
participants to give or take such action or would otherwise act upon the
instructions of beneficial owners owning through them.

      The Depository has advised the Company that it will take any action
permitted to be taken by a Holder of Exchange Notes (including the presentation
of Exchange Notes for exchange as described below) only at the direction of one
or more participants to whose account with the Depository interests in the
Global Exchange Note are credited and only in respect of such portion of the
aggregate principal amount of the Exchange Notes as to which such participant or
participants has or have given such direction.

      The Depository has advised the Company that the Depository is a
limited-purpose trust company organized under the Banking Law of the State of
New York, a "banking organization" within the meaning of New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code and a "clearing agency"
registered under the Exchange Act. The Depository was created to hold the
securities of its participants and to facilitate the clearance and settlement of
securities transactions among its participants in such securities through
electronic book entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depository's participants include securities brokers and dealers (including the
Initial Purchasers), banks, trust companies, clearing corporations and certain
other organizations some of whom (and/or their representatives) own the
Depository. Access to the Depository's book entry system is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly.

CERTIFICATED EXCHANGE NOTES

      The Exchange Notes represented by a Global Exchange Note are exchangeable
for certificated Exchange Notes only if (i) the Depository notifies the Company
that it is unwilling or unable to continue as a depository for such Global
Exchange Note or if at any time the Depository ceases to be a clearing agency
registered under the Exchange Act, and a successor depository is not appointed
by the Company within 90 days, (ii) the Company executes and delivers to the
Trustee a notice that such Global Exchange Note shall be so transferable,
registrable and exchangeable, and such transfer shall be registrable or (iii)
there shall have occurred and be continuing an Event of Default or an event
which, with the giving of notice or lapse of time or both, would constitute an
Event of Default with respect to the Exchange Notes represented by such Global
Exchange Note. Any Global Exchange Note that is exchangeable for certificated
Exchange Notes pursuant to the preceding sentence will be transferred to, and
registered and exchanged for, certificated Exchange Notes in authorized
denominations and registered in such names as the Depository or its nominee
holding such Global Exchange Note may direct. Subject to the foregoing, a Global
Exchange Note is not exchangeable, except for a Global Exchange Note of like
denomination to be registered in the name of the Depository or its nominee. In
the event that a Global Exchange Note becomes exchangeable for certificated
Exchange Notes, (i) certificated Exchange Notes will be issued only in fully
registered form in denominations of $1,000 or integral multiples thereof, (ii)
payment of principal, any repurchase price, and interest on the certificated
Exchange Notes will be payable, and the transfer of the certificated Exchange
Notes will be registrable, at the office or agency of the Company maintained for
such purposes, and (iii) no service charge will be made for any issuance of the
certificated Exchange Notes, although the Company may require payment of a sum
sufficient to cover any tax or governmental charge imposed in connection
therewith.

SUBORDINATION OF THE EXCHANGE NOTES

      The payment of the principal of, and premium, if any, and interest on the
Exchange Notes will be subordinated in right of payment, as set forth in Article
Thirteen of the Indenture, to the prior payment in 

                                       79
<PAGE>
full of Senior Indebtedness, which will include borrowings under the Credit
Facility, whether outstanding on the date of the Indenture or thereafter
incurred. In the event of any insolvency or bankruptcy case or proceeding, or
any receivership, liquidation, reorganization or other similar case or
proceeding in connection therewith, relating to the Company or to its creditors,
as such, or to its assets, or any liquidation, dissolution or other winding-up
of the Company, whether voluntary or involuntary and whether or not including
insolvency or bankruptcy, or any assignment for the benefit of creditors or
other marshalling of assets or liabilities of the Company (provided that this
provision will not require the repayment of all Senior Indebtedness in full in
connection with the consolidation or merger of the Company or its liquidation or
dissolution following the conveyance, transfer, lease or other disposition of
all or substantially all the properties and assets of the Company and its
Restricted Subsidiaries on a consolidated basis upon the terms and conditions
described under the "Consolidation, Merger and Sale of Assets" covenant
described below as a prerequisite to any payments being made to Holders of
Notes), the holders of Senior Indebtedness will first be entitled to receive
payment in full of all amounts due on or in respect of all Senior Indebtedness,
or provision must be made for such payment, before the Holders of Notes will be
entitled to receive any direct or indirect payment or distribution of any kind
or character (other than any payment or distribution in the form of Permitted
Junior Securities) on account of principal of (or premium, if any, on) or
interest on the Notes or on account of the purchase or redemption or other
acquisition of the Notes (including pursuant to an optional redemption or a
Redemption Event). In the event that, notwithstanding the foregoing, the Trustee
or the Holder of any Note receives any payment or distribution of properties or
assets of the Company of any kind or character, whether in cash, property or
securities, by set-off or otherwise, in respect of principal of (or premium, if
any, on) or interest on the Notes before all Senior Indebtedness is paid or
provided for in full, then the Trustee or the Holders of Notes receiving any
such payment or distribution (other than a payment or distribution in the form
of Permitted Junior Securities) will be required to pay or deliver such payment
or distribution forthwith to the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee, agent or other Person making payment or
distribution of properties of assets of the Company for application to the
payment of all Senior Indebtedness remaining unpaid, to the extent necessary to
pay all Senior Indebtedness in full.

      The Company also may not make any payment or distribution of any
properties or assets of the Company of any kind or character (other than
Permitted Junior Securities) on account of principal of (or premium, if any, on)
or interest on the Notes or on account of the purchase or redemption or other
acquisition of Notes upon the occurrence of a Payment Event of Default with
respect to any Specified Senior Indebtedness and receipt by the Trustee of
written notice thereof until such Payment Event of Default shall have been cured
or waived or shall have ceased to exist or such Specified Senior Indebtedness
shall have been paid in full or otherwise discharged, after which the Company
shall resume making any and all required payments in respect of the Notes,
including any missed payments.

      The Company also may not make any payment or distribution of any
properties or assets of the Company of any kind or character (other than
Permitted Junior Securities) on account of any principal of (or premium, if any,
on) or interest on the Notes or on account of the purchase or redemption or
other acquisition of Notes for the period specified below ("Payment Blockage
Period") upon the occurrence of a Non-payment Event of Default with respect to
any Specified Senior Indebtedness and receipt by the Trustee and the Company of
written notice thereof from one or more of the holders of such Specified Senior
Indebtedness (or their representative). The Payment Blockage Period will
commence upon the earlier of the dates of receipt by the Trustee or the Company
of such notice from one or more of the holders of such Specified Senior
Indebtedness (or their representative) and shall end on the earliest of (i) 179
days thereafter, (ii) the date, as set forth in a written notice from the
holders of the Specified Senior Indebtedness (or their representative) to the
Company or the Trustee, on which such Non-payment Event of Default is cured,
waived in writing or ceases to exist or such Specified Senior Indebtedness is
discharged or (iii) the date on which such Payment Blockage Period shall have
been terminated by written notice to the Company or the Trustee from one or more
of such holders (or their representative) initiating

                                       80
<PAGE>
such Payment Blockage Period, after which the Company will resume (unless
otherwise prohibited pursuant to the immediately preceding paragraph) making any
and all required payments in respect of the Notes, including any missed
payments. In any event, not more than one Payment Blockage Period may be
commenced during any period of 360 consecutive days. No Non-payment Event of
Default that existed or was continuing on the date of delivery of any Payment
Blockage Notice to the Trustee can be made the basis for a subsequent Payment
Blockage Notice. In the event that, notwithstanding the foregoing, the Company
makes any payment to the Trustee or the Holder of any Exchange Note prohibited
by the subordination provision of the Indenture, then such payment will be
required to be paid over and delivered forthwith to the Company.

      If the Company fails to make any payment on the Notes when due or within
any applicable grace period, whether or not on account of the payment blockage
provision described above, such failure would constitute an Event of Default
under the Indenture and would enable the Holders of the Notes to accelerate the
maturity thereof. See " -- Events of Default and Remedies."

      As a result of such subordination provisions described above, in the event
of a distribution of assets upon the liquidation, receivership, reorganization
or insolvency of the Company, creditors of the Company who are holders of Senior
Indebtedness may recover more, ratably, than the Holders of the Notes, and
assets which would otherwise be available to pay obligations in respect of the
Notes will be available only after all Senior Indebtedness has been paid in
full, and there may not be sufficient assets remaining to pay amounts due on any
or all of the Exchange Notes.

      The subordination provisions described above will cease to be applicable
to the Exchange Notes upon any Legal Defeasance or Covenant Defeasance of the
Exchange Notes as described under "-- Legal Defeasance and Covenant
Defeasance."

      Senior Indebtedness may also be issued and incurred in the future, subject
only to certain limitations contained in the covenant described under "Certain
Covenants -- Limitation on Indebtedness for Money Borrowed." The Exchange
Notes will also be structurally subordinated to all liabilities of the Company's
Subsidiaries.

CERTAIN COVENANTS

      RESTRICTIONS ON DIVIDENDS, REDEMPTIONS AND OTHER PAYMENTS

      (a) The Indenture provides that the Company shall not, either directly or
indirectly through any Restricted Subsidiary, (i) declare or pay any dividend,
either in cash or property, on any shares of its capital stock (except dividends
or other distributions payable solely in shares of capital stock of the
Company), (ii) purchase, redeem or retire any shares of its capital stock or any
warrants, rights or options to purchase or acquire any shares of its capital
stock or (iii) make any other payment or distribution in respect of the
Company's capital stock (such dividends, purchases, redemptions, retirements,
payments and distributions being herein collectively called "Restricted
Payments") if, after giving effect thereto,

            (1) an Event of Default would have occurred; or

            (2) (A) the sum of (i) such Restricted Payments plus (ii) the
      aggregate amount of all Restricted Payments made during the period after
      the date of the Indenture would exceed (B) the sum of (i) $5 million plus
      (ii) 25% of the Company's Consolidated Net Income subsequent to March 31,
      1997 (with 100% reduction for a loss).

      (b) Notwithstanding paragraph (a) above, the Company may take the
following actions so long as no Event of Default shall have occurred and be
continuing:

                                       81
<PAGE>
            (1) the payment of dividends on any of the shares of the Series A
      Preferred Stock of the Company outstanding on the date of this Indenture;

            (2) the payment of any dividend on any other Capital Stock of the
      Company or any Restricted Subsidiary within 60 days after the date of
      declaration thereof, if at such declaration date such declaration complied
      with the provisions of paragraph (a) above (and such payment shall be
      deemed to have been paid on such date of declaration for purposes of any
      calculation required by the provisions of paragraph (a) above); and

            (3) the repurchase, redemption or other acquisition or retirement of
      any shares of (A) the Series A Preferred Stock of the Company outstanding
      on the date of this Indenture and (B) any class of capital stock of the
      Company or any Restricted Subsidiary, in exchange for, or out of the
      aggregate net cash proceeds of a substantially concurrent issue and sale
      (other than to a Restricted Subsidiary) of shares of common stock of the
      Company.

The actions described in clauses (1), (2) and (3) of this paragraph (b) shall be
Restricted Payments that shall be permitted to be taken in accordance with this
covenant and shall not reduce the amount that would otherwise be available for
Restricted Payments under clause (2) of paragraph (a). For purposes of this
covenant, the amount of any Restricted Payment payable in property shall be
deemed to be the fair market value of such property as determined by the Board
of Directors of the Company. (Section 1006)

      LIMITATION ON INDEBTEDNESS FOR BORROWED MONEY

      The Indenture provides that the Company will not, and will not permit any
Restricted Subsidiary to, create, incur, assume, guarantee or become liable
("incur") with respect to any Indebtedness for Money Borrowed, including
Acquired Indebtedness but excluding Permitted Indebtedness, if, immediately
after giving effect to any such creation, incurrence, assumption or guarantee
(including giving effect to the retirement of any existing Indebtedness for
Money Borrowed from the proceeds of such additional Indebtedness for Money
Borrowed):

            (1) The ratio of (a) the aggregate amount of the outstanding
      Indebtedness for Money Borrowed of the Company and its Restricted
      Subsidiaries as of the end of the immediately preceding fiscal quarter of
      the Company, as determined on a consolidated basis in accordance with
      GAAP, to (b) the Consolidated EBITDA for the immediately preceding four
      fiscal quarters of the Company, would exceed 10.0 to 1.0; or

            (2) The Interest Coverage Ratio would have been at least 2.4 to 1.0.

Further, the Indenture will provide that the Company will not permit any
Restricted Subsidiary to incur any Indebtedness for Money Borrowed (except to
the Company or another Restricted Subsidiary) that is expressly subordinate in
right of payment to any other Indebtedness for Money Borrowed of such Restricted
Subsidiary. (Section 1007)

      LIENS

      The Indenture provides that the Company will not, and will not permit any
Restricted Subsidiary to, directly or indirectly, create, incur, assume or
suffer to exist any Lien of any kind, except for Permitted Liens, upon any of
their respective assets or properties, whether now owned or acquired after the
date of the Indenture, or any income or profits therefrom to secure any Pari
Passu Indebtedness or Subordinated Indebtedness, unless prior to or
contemporaneously therewith the Notes are directly secured equally and ratably,
provided that (1) if such secured indebtedness is Pari Passu Indebtedness, the
Lien

                                       82
<PAGE>
securing such Pari Passu Indebtedness shall be subordinate and junior to, or
PARI PASSU with, the Lien securing the Notes and (2) if such secured
indebtedness is Subordinated Indebtedness, the Lien securing such Subordinated
Indebtedness shall be subordinate and junior to the Lien securing the Notes at
least to the same extent as such Subordinated Indebtedness is subordinated to
the Notes. The foregoing covenant will not apply to any Lien securing Acquired
Indebtedness, provided that any such Lien extends only to the properties or
assets that were subject to such Lien prior to the related acquisition by the
Company or such Restricted Subsidiary and was not created, incurred or assumed
in contemplation of such transaction. (Section 1008)

      LIMITATION ON RANKING OF FUTURE INDEBTEDNESS

      The Indenture provides that the Company will not incur or permit to remain
outstanding any Indebtedness for Money Borrowed (including Acquired Indebtedness
and Permitted Indebtedness) which is expressly subordinate in right of payment
to any Senior Indebtedness, other than Subordinated Indebtedness or Pari Passu
Indebtedness. For purposes of this covenant, the incurrence of Senior
Indebtedness which is unsecured shall not, because of its unsecured status, be
deemed to be subordinate in right of payment to any Senior Indebtedness which is
secured. (Section 1013)

      LIMITATIONS ON RESTRICTED SUBSIDIARY DIVIDENDS

      The Indenture provides that the Company shall not and shall not permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise cause to
become effective any encumbrance or restriction of any kind on the ability of
any Restricted Subsidiary to (a) pay dividends in cash or make any other
distribution on its capital stock to the Company or any other Restricted
Subsidiary, (b) pay any indebtedness owed to the Company or any other Restricted
Subsidiary, (c) make loans, advances, or capital contributions to the Company or
any other Restricted Subsidiary, or (d) transfer any of its properties or assets
to the Company or another Restricted Subsidiary, except in each instance (i) as
set forth in the instrument evidencing or the agreement governing Acquired
Indebtedness of any acquired Person which becomes a Restricted Subsidiary,
provided, that any restriction or encumbrance under such instrument or agreement
existed at the time of acquisition, was not put in place in anticipation of such
acquisition, and is not applicable to any Person, other than the Person or
property or assets of the Person so acquired; (ii) customary provisions of any
lease or license of the Company or any Restricted Subsidiary relating to the
property covered thereby and entered into in the ordinary course of business;
(iii) any encumbrance or restriction arising under applicable law; (iv) any
encumbrance or restriction arising under the Indenture, the Credit Facility, or
other indebtedness or other agreements existing on the date of original issuance
of the Notes; (v) any restrictions with respect to a Restricted Subsidiary
imposed pursuant to an agreement that has been entered into for the sale or
disposition of the stock, business, assets or properties of such Restricted
Subsidiary; (vi) any encumbrance or restriction arising under the terms of
purchase money obligations, but only to the extent such purchase money
obligations restrict or prohibit the transfer of the property so acquired; (vii)
any encumbrance or restriction arising under customary non-assignment provisions
in installment purchase contracts; (viii) any encumbrance or restriction on the
ability of any Restricted Subsidiary to transfer any of its property acquired
after the date of the Indenture to the Company or any other Restricted
Subsidiary that is required by a lender to, or purchaser of any indebtedness of,
such Restricted Subsidiary in connection with a financing of the acquisition of
such property (including with respect to the purchase of asset portfolios and
pursuant to the underwriting or origination of mortgage loans) by such
Restricted Subsidiary; and (ix) any encumbrance or restriction pursuant to any
agreement that extends, refinances, renews or replaces any agreement described
in the foregoing clauses (i) through (viii), and except with respect to clause
(d) only, restrictions in the form of Liens which are not prohibited as
described in the "Liens" covenant and which contain customary limitations on the
transfer of collateral. (Section 1014)

                                       83
<PAGE>
      LIMITATION ON TRANSACTIONS WITH AFFILIATES

      The Indenture provides that the Company shall not, and shall not permit
any of its Restricted Subsidiaries to, enter into any transaction (or series of
related transactions), including, without limitation, the sale, purchase, lease,
or exchange of any property or the rendering of any service (a "Transaction"),
involving payments in excess of $50,000, with any Affiliate of the Company
(other than the Company or a Restricted Subsidiary), on terms and conditions
less favorable to the Company or such Restricted Subsidiary, as the case may be,
than would be available at such time in a comparable Transaction in arm's length
dealings with an unrelated Person as determined by the Board of Directors, such
approval to be evidenced by a Board Resolution.

      The provisions of the immediately preceding paragraph will not apply to:
(1) Restricted Payments otherwise permitted pursuant to the covenant described
under " -- Restrictions on Dividends, Redemptions and Other Payments"; (2) fees
and compensation (including amounts paid pursuant to employee benefit plans)
paid to, and indemnity provided on behalf of, officers, directors, employees or
consultants of the Company or any Restricted Subsidiary, as determined by the
Board of Directors or the senior management thereof in the exercise of their
reasonable business judgment; or (3) payments for goods and services purchased
in the ordinary course of business on an arm's length basis. (Section 1015)

      REPORTS

      So long as the Company is a reporting company under the Exchange Act, the
Company will furnish to Holders of the Exchange Notes annual reports of the
Company containing audited consolidated financial statements and interim reports
with unaudited consolidated summary financial data on a quarterly basis. If the
Company ceases to be a reporting company under the Exchange Act, the Company
will furnish to Holders of the Exchange Notes annual audited consolidated
financial statements and quarterly unaudited consolidated summary financial
statements. (Section 704)

EVENTS OF DEFAULT AND REMEDIES

      An Event of Default will include: (i) failure to pay the principal of or
premium, if any, on the Notes when due at Stated Maturity, upon redemption or
upon acceleration, as provided in the Indenture, whether or not prohibited by
the subordination provisions of the Indenture, (ii) failure to pay any interest
on the Notes for 30 days, whether or not prohibited by the subordination
provisions of the Indenture, (iii) failure to give the Company Notice as
described under "-- Repurchase at Option of Holders in Certain Circumstances,"
(iv) failure to perform, or a breach of, any other covenant or agreement set
forth in the Indenture for 30 days after receipt of written notice from the
Trustee or Holders of at least 25% in aggregate principal amount of the
outstanding Notes specifying the default and requiring the Company to remedy
such default, (v) default in the payment at Stated Maturity of Indebtedness for
Money Borrowed of the Company or any Restricted Subsidiary having an outstanding
principal amount due at Stated Maturity greater than $2.5 million and such
default having continued for a period of 30 days beyond any applicable grace
period, (vi) an event of default as defined in any mortgage, indenture or
instrument of the Company or any Restricted Subsidiary shall have happened and
resulted in acceleration of Indebtedness for Money Borrowed which, together with
the principal amount of any other Indebtedness for Money Borrowed so
accelerated, exceeds $2.5 million or more at any time, and such default shall
not be cured or waived and such acceleration shall not have been rescinded or
annulled within a period of 30 days from the occurrence of such acceleration,
(vii) certain events of insolvency, receivership or reorganization of the
Company or any Material Subsidiary and (viii) entry of a final judgment, decree
or order against the Company or any Material Subsidiary for the payment of money
in excess of $2.5 million and such judgment, decree or order continues
unsatisfied for 30 days without a stay of execution. (Section 501)

                                       84
<PAGE>
      If any Event of Default (other than as specified in clause (vii) above)
occurs and is continuing, the Trustee, by written notice to the Company, or the
Holders of at least 25% in aggregate principal amount of the Notes then
outstanding, by notice to the Trustee and the Company, may, and the Trustee upon
the request of the Holders of not less than 25% in aggregate principal amount of
the Notes then outstanding shall, declare the principal of, premium, if any, and
accrued interest on all of the Notes due and payable immediately, upon which
declaration all amounts payable in respect of the Notes shall be immediately due
and payable. If an Event of Default specified in clause (vii) above occurs and
is continuing, then the principal of, premium, if any, and accrued interest on
all of the Notes then outstanding shall automatically become and be immediately
due and payable without any declaration, notice or other act on the part of the
Trustee or any Holder of Notes. (Section 502)

      After a declaration of acceleration under the Indenture, but before a
judgment or decree for payment of the money due has been obtained by the
Trustee, the Holders of a majority in aggregate principal amount of the
outstanding Notes, by written notice to the Company and the Trustee, may rescind
such declaration if (a) the Company has paid or deposited with the Trustee a sum
sufficient to pay (i) all sums paid or advanced by the Trustee under the
Indenture and the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agents and counsel, (ii) all overdue interest on all Notes,
(iii) the principal of (and premium, if any, on) any Notes which have become due
otherwise than by such declaration of acceleration and interest thereon at the
rate borne by the Notes, and (iv) to the extent that payment of such interest is
lawful, interest upon overdue interest and overdue principal at the rate borne
by the Notes (without duplication of any amount paid or deposited pursuant to
clause (ii) or (iii) ); (b) the rescission would not conflict with any judgment
or decree of a court of competent jurisdiction; and (c) all Events of Default,
other than the nonpayment of principal of (and premium, if any, on) or interest
on the Notes that has become due solely by such declaration of acceleration,
have been cured or waived. (Section 502)

      No Holder of any of the Exchange Notes will have any right to institute
any proceeding with respect to the Indenture or any remedy thereunder, unless
such Holder has notified the Trustee of a continuing Event of Default and the
Holders of at least 25% in aggregate principal amount of the outstanding Notes
have made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as Trustee under the Notes and the Indenture, the
Trustee has failed to institute such proceeding within 60 days after receipt of
such notice and the Trustee, within such 60-day period, has not received
directions inconsistent with such written request by Holders of a majority in
aggregate principal amount of the outstanding Exchange Notes. Such limitations
will not apply, however, to a suit instituted by a Holder of a Note for the
enforcement of the payment of the principal of (or premium, if any, on) or
interest on such Exchange Note on or after the respective due dates expressed in
such Exchange Note. (Section 507 and 508)

      During the existence of an Event of Default, the Trustee will be required
to exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent person would
exercise under the circumstances in the conduct of such person's own affairs.
Subject to the provisions of the Indenture relating to the duties of the Trustee
in case an Event of Default shall occur and be continuing, the Trustee will not
be under any obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders of Notes unless such
Holders shall have offered to the Trustee reasonable security or indemnity.
Subject to certain provisions concerning the rights of the Trustee, the Holders
of a majority in aggregate principal amount of the outstanding Notes will have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee, or exercising any trust or power conferred
on the Trustee under the Indenture. (Sections 512, 601 and 603)

                                       85
<PAGE>
      The Holders of not less than a majority in aggregate principal amount of
the Notes then outstanding may on behalf of the Holders of all of the Notes
waive any existing Default or Event of Default and its consequences, except in
respect of the payment of the principal of (or premium, if any, on) or interest
on any Note or in respect of a provision of the Indenture which cannot be
modified or amended without the consent of the Holder of each Note affected
thereby as described below under " -- Modification and Waiver." (Section 513)

      If a Default or an Event of Default occurs and is continuing and is known
to the Trustee, the Trustee shall mail to each Holder of Notes notice of the
Default or Event of Default within 90 days after the occurrence thereof. Except
in the case of a Default or an Event of Default in payment of principal of (or
premium, if any, on) or interest on any Notes, the Trustee may withhold the
notice to the Holders of Notes if the Trustee determines in good faith that
withholding the notice is in the interest of such Holders. (Section 602)

      The Company is required to deliver to the Trustee annual and quarterly
statements regarding compliance with the Indenture, and the Company will also be
required, upon becoming aware of any Default or Event of Default, to deliver to
the Trustee a statement specifying such Default or Event of Default. (Section
1011)

REPURCHASE AT OPTION OF HOLDERS IN CERTAIN CIRCUMSTANCES

      If Senior Indebtedness of the Company and its Restricted Subsidiaries is
not less than the greater of (i) $50 million and (ii) 45% of Total Consolidated
Assets for at least 30 consecutive days during any consecutive 12 month period
after August 1, 1997 (a "Repurchase Event"), each Holder of Notes shall have the
right, at the Holder's option, to require the Company to repurchase all of such
Holder's Notes, or any portion of the principal amount thereof that is equal to
$1,000 or an integral multiple of $1,000 in excess thereof, on the date (the
"Repurchase Date") that is 45 days after the date of the Company Notice (as
defined), at a price equal to (i) if the Repurchase Event occurs on or prior to
July 31, 2000, 104% of the principal amount, (ii) if the Repurchase Event occurs
after July 31, 2000 and on or prior to July 31, 2001, 102% and (ii) if the
Repurchase Event occurs thereafter, 100% of the principal of the principal
amount of the Notes to be repurchased, together with interest accrued to the
Repurchase Date (the "Repurchase Price").

      Within 30 days after the occurrence of a Repurchase Event, the Company is
obligated to give to all Holders of the Notes notice, as provided in the
Indenture (the "Company Notice"), of the occurrence of such Repurchase Event and
of the repurchase right arising as a result thereof, or, at the request of the
Company on or before the 15th day after such occurrence, the Trustee shall give
the Company Notice. The Company must also deliver a copy of the Company Notice
to the Trustee and to the office of each Paying Agent. To exercise the
repurchase right, a Holder of Notes must deliver written notice to the Trustee
or any Paying Agent of the Holder's exercise of such right, together with the
Notes with respect to which the right is being exercised, in accordance with the
procedures set forth in the Indenture.

      Any repurchase in connection with a Repurchase Event could, depending on
the circumstances and absent a waiver from the holders of Senior Indebtedness,
be blocked by the subordination provisions of the Debentures. See "--
Subordination of the Exchange Notes." Failure by the Company to repurchase the
Notes when required may result in an Event of Default with respect to the Notes
whether or not such repurchase is permitted by the subordination provisions. See
"-- Events of Default and Remedies."

      Rule 13e-4 under the Exchange Act requires the dissemination of certain
information to security holders in the event of an issuer tender offer and may
apply in the event that the repurchase option 

                                       86
<PAGE>
becomes available to Holders of the Notes. The Company will comply with this
rule to the extent applicable at that time.

      The foregoing provisions would not necessarily afford Holders of the
Exchange Notes protection in the event of highly leveraged or other transactions
involving the Company that may adversely affect Holders.

REDEMPTION AT OPTION OF THE COMPANY

      The Exchange Notes will not be redeemable at the Company's option prior to
September 15, 2000. Thereafter, the Exchange Notes will be subject to redemption
at the option of the Company, in whole or in part, upon not less than 30 or more
than 60 days' notice mailed to the registered Holders thereof, at the redemption
prices (expressed as percentages of principal amount) set forth below plus
accrued and unpaid interest to the applicable redemption date, if redeemed
during the twelve-month period beginning on September 15 of the years indicated
below:

      The redemption price will be paid with interest accrued to the date fixed
for redemption. If the Company elects to redeem less than all of the Notes, the
Trustee will select which Notes to redeem by lot or such other method as it
shall deem fair and appropriate, including the selection for redemption of a
portion of the principal amount of any Note but not less than $1,000. On and
after the redemption date, interest will cease to accrue on the Exchange Notes
or portions thereof called for redemption. (Article Eleven)

MODIFICATION AND WAIVER

      With certain limited exceptions which permit modifications of the
Indenture by the Company and the Trustee only, the Indenture may be modified by
the Company with the consent of Holders of not less than a majority in aggregate
principal amount of outstanding Notes; provided however, that no such changes
shall without the consent of the Holder of each Note affected thereby (i) change
the maturity date of the principal of, or the due date of any installment of
interest on, any Note, (ii) reduce the principal of, or the rate of interest on,
any Note, (iii) change the place of payment or the currency in which any portion
of the principal of, or interest on, any Note is payable, (iv) impair the right
to institute suit for the enforcement of any such payment, (v) reduce the
above-stated percentage of Holders of the outstanding Notes necessary to modify
the Indenture, (vi) modify the foregoing requirements or reduce the percentage
of outstanding Notes necessary to waive any past default or certain covenants or
(vii) reduce the relative ranking of the Notes. (Section 902)

      The Holders of a majority in aggregate principal amount of outstanding
Notes may waive compliance by the Company with certain covenants, most of which
are described above under " -- Certain Covenants." (Section 1012)

CONSOLIDATION, MERGER AND SALE OF ASSETS

      The Company may not consolidate with, merge with, or transfer all or
substantially all of its assets to another entity where the Company is not the
surviving corporation unless (i) such other entity assumes the Company's
obligations under the Indenture, (ii) such other entity shall be a Person
organized and 

                                       87
<PAGE>
existing under the laws of the United States of America, any state thereof or
the District of Columbia, and (iii) after giving effect thereto, no event shall
have occurred and be continuing which, after notice or lapse of time, would
become an Event of Default. (Section 801)

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

      The Company may, at its option and at any time, elect to have all of the
obligations of the Company discharged with respect to the outstanding Notes
("Legal Defeasance"). Such Legal Defeasance means that the Company shall be
deemed to have paid and discharged the entire indebtedness represented by the
outstanding Notes and to have been discharged from all their other obligations
with respect to such Notes, except for (i) the rights of Holders of outstanding
Notes to receive payment in respect of the principal of and premium, if any, and
interest on such Notes when such payments are due, (ii) the Company's
obligations to replace any temporary Notes, register the transfer or exchange of
any Notes, replace mutilated, destroyed, lost or stolen Notes and maintain an
office or agency for payments in respect of the Notes, (iii) the rights, powers,
trusts, duties and immunities of the Trustee, and (iv) the Legal Defeasance
provisions of the Indenture. In addition, the Company may, at its option and at
any time, elect to have the obligations of the Company released with respect to
certain covenants that are described in the Indenture, some of which are
described under " -- Certain Covenants" above, and thereafter any omission to
comply with such obligations shall not constitute a Default or an Event of
Default with respect to the Notes ("Covenant Defeasance"). In the event Covenant
Defeasance occurs, certain events (not including nonpayment, bankruptcy,
insolvency and reorganization events) described under " -- Events of Default and
Remedies" will no longer constitute an Event of Default with respect to the
Notes. In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the Notes, cash in United States dollars, Government
Obligations (as defined in the Indenture), or a combination thereof, in such
amounts as will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of (and premium, if any,
on) and interest on the outstanding Notes to redemption or maturity; (ii) the
Company shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of the outstanding Notes will not recognize income, gain or
loss for federal income tax purposes as a result of such Legal Defeasance or
Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if
such Legal Defeasance or Covenant Defeasance had not occurred (in the case of
Legal Defeasance, such opinion must refer to and be based upon a published
ruling of the Internal Revenue Service or a change in applicable federal income
tax laws); (iii) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit or insofar as clause (vi) under the first
paragraph under " -- Events of Default and Remedies" is concerned, at any time
during the period ending on the 91st day after the date of deposit; (iv) such
Legal Defeasance or Covenant Defeasance shall not cause the Trustee to have a
conflicting interest under the Indenture or the Trust Indenture Act of 1939 with
respect to any securities of the Company; (v) such Legal Defeasance or Covenant
Defeasance shall not result in a breach or violation of, or constitute a default
under, any other material agreement or instrument to which the Company is a
party or by which it is bound; and (vi) the Company shall have delivered to the
Trustee an Officers' Certificate and an Opinion of Counsel, which, taken
together, state that all conditions precedent under the Indenture to either
Legal Defeasance or Covenant Defeasance, as the case may be, have been complied
with. (Article Twelve)

SATISFACTION AND DISCHARGE OF INDENTURE

      The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights of registration of transfer or exchange of the
Notes, as expressly provided for in the Indenture) as to all outstanding Notes
when (i) either (a) all the Notes theretofore authenticated and delivered
(except lost, stolen or destroyed Notes which have been replaced or

                                       88
<PAGE>
paid and Notes for whose payment money or Government Obligations have
theretofore been deposited in trust or segregated and held in trust by the
Company and thereafter repaid to the Company or discharged from such trust) have
been delivered to the Trustee for cancellation or (b) all Notes not theretofore
delivered to the Trustee for cancellation have become due and payable or will
become due and payable at their Stated Maturity within one year, or are to be
called for redemption within one year under arrangements satisfactory to the
Trustee for the serving of notice of redemption by the Trustee in the name, and
at the expense, of the Company, and the Company has irrevocably deposited or
caused to be deposited with the Trustee funds in an amount sufficient to pay and
discharge the entire indebtedness on the Notes not theretofore delivered to the
Trustee for cancellation, for principal of (and premium, if any, on) and
interest on the Notes to the date of deposit (in the case of Notes which have
become due and payable) or to the Stated Maturity or redemption date, as the
case may be, together with instructions from the Company irrevocably directing
the Trustee to apply such funds to the payment thereof at maturity or
redemption, as the case may be; (ii) the Company has paid all other sums then
due and payable under the Indenture by the Company; and (iii) the Company has
delivered to the Trustee an Officers' Certificate and an Opinion of Counsel,
which, taken together, state that all conditions precedent under the Indenture
relating to the satisfaction and discharge of the Indenture have been complied
with. (Sections 401 and 402)

GOVERNING LAW

      The Indenture and the Exchange Notes will be governed and construed in
accordance with the laws of the State of New York. (Section 113)

THE TRUSTEE

      American Stock Transfer & Trust Company is the Trustee under the

of the Trustee by the Company under certain circumstances. (Section 607)

      The Indenture (including the provisions of the Trust Indenture Act of 1939
incorporated by reference therein) will contain limitations on the rights of the
Trustee thereunder, should it become a creditor of the Company, to obtain
payment of claims in certain cases or to realize on certain property received by
it in respect of any such claims, as security or otherwise. The Trustee is
permitted to engage in other transactions; PROVIDED, HOWEVER, if it acquires any
conflicting interest (as defined in the Trust Indenture Act of 1939) it must
eliminate such conflict or resign. (Sections 613 and 614)

                     DESCRIPTION OF THE OUTSTANDING NOTES

      The terms of the Outstanding Notes are identical in all material respects
to the Exchange Notes, except that the Outstanding Notes have not been
registered under the Securities Act, are subject to certain restrictions on
transfer and are entitled to certain registration rights under the Registration
Agreement (which rights terminate upon the consummation of the Exchange Offer,
except under limited circumstances). The Exchange Notes will not provide for any
increase in the interest rate thereon. In that regard, the Outstanding Notes
provide that if an (i) exchange offer registration statement or resale shelf
registration statement is not filed by October 1, 1997 or (ii) exchange offer
registration statement is not declared effective by November 15, 1997, Special
Interest will accrue and be payable quarterly until such time as an exchange
offer registration statement is filed or becomes effective, as the case may be.
In addition, (i) if an exchange offer is not consummated or a resale shelf
registration statement is not declared effective by December 31, 1997 or (ii) if
either the exchange offer registration statement or the resale shelf
registration statement has been declared effective and such registration
statement ceases to be effective or usable (subject to certain exceptions) in
connection with resale of Exchange Notes or Outstanding Notes during periods
specified in the Registration Agreement, Special Interest will accrue and be
payable quarterly until such time as an exchange offer is consummated or a
resale shelf registration statement is declared effective, as the case may be,
or until the exchange offer registration statement or resale registration
statement may again be used. Special Interest will accrue at a rate of 0.5% per
annum during the 90-day period immediately following the occurrence of any
failure to comply with the requirements set forth above and shall increase by
0.25% per annum at the end of each subsequent 90-day period, but in no event
shall such rate exceed 1.50% per annum. The Exchange Notes are not entitled to
any such Special Interest. In addition, the Outstanding Notes and the Exchange
Notes will constitute a single series of debt securities under the Indenture.
See "Description of the Exchange Notes."

                   CERTAIN FEDERAL INCOME TAX CONSEQUENCES

      The following summary describes certain United States Federal income tax
consequences generally applicable to a holder that exchanges Outstanding Notes
for Exchange Notes in the Exchange Offer. This discussion is based on the
Internal Revenue Code of 1986, as amended to the date hereof (the "Code"),
existing and proposed Treasury regulations, and judicial and administrative
determinations, all of which are subject to change at any time, possibly on a
retroactive basis. It relates only to persons who hold their Outstanding Notes,
and will hold Exchange Notes exchanged therefor, as "capital assets" within the
meaning of Section 1221 of the Code. It does not discuss state, local or foreign
tax consequences, nor, except as otherwise noted, does it discuss tax
consequences to categories of holders that are subject to special rules, such as
foreign persons, tax-exempt organizations, insurance companies, banks and
dealers in stocks and securities. Tax consequences may vary depending on the
particular status of an investor. No rulings will be sought from the Internal
Revenue Service ("IRS") with respect to the Federal income tax consequences of
the Exchange Offer.

      THIS SECTION DOES NOT PURPORT TO DEAL WITH ALL ASPECTS OF FEDERAL INCOME
TAXATION THAT MAY BE RELEVANT TO AN INVESTOR'S DECISION TO PARTICIPATE IN THE
EXCHANGE OFFER. EACH INVESTOR SHOULD CONSULT WITH ITS OWN TAX ADVISOR CONCERNING
THE APPLICATION OF THE FEDERAL INCOME TAX LAWS AND OTHER TAX LAWS TO ITS
PARTICULAR SITUATION BEFORE DETERMINING WHETHER TO EXCHANGE ITS OUTSTANDING
NOTES FOR EXCHANGE NOTES.

THE EXCHANGE OFFER

      Under recently-issued Treasury regulations, the exchange of Outstanding
Notes for Exchange Notes pursuant to the Exchange Offer should not constitute a
significant modification of the terms of the Outstanding Notes and, accordingly,
such exchange should be treated as a "nonevent" for Federal income

                                       96
<PAGE>
tax purposes. Therefore, such exchange should have no Federal income tax
consequences to holders of Outstanding Notes who participate in the exchange,
and each such holder would continue to be required to include interest on the
Exchange Notes in its gross income in accordance with its method of accounting
for Federal income tax purposes.

TREATMENT OF INTEREST

      In general, interest on an Outstanding Note or Exchange Note will be
taxable to a beneficial owner who or which is (i) a citizen or resident of the
United States, (ii) a corporation created or organized under the laws of the
United States or any State thereof (including the District of Columbia) or (iii)
a person otherwise subject to United States Federal income taxation on its
worldwide income (a "U.S. Holder") as ordinary income at the time it is received
or accrued, depending on the U.S. Holder's method of accounting for tax
purposes.

      Under the tax rules relating to original issue discount, holders of debt
instruments issued at a discount that exceeds a nominal amount may be required
to recognize taxable interest income prior to the receipt or accrual of stated
interest. The Outstanding Notes were treated by the Company as issued without
taxable original issue discount. In the case of a debt instrument issued that
provides for contingent payments, Treasury Regulations provide that such
payments will not be taken into account in computing original issue discount if
there is a remote likelihood that the payments will occur. Had the Company
failed to effect the Exchange Offer on a timely basis, special interest (the
"Special Interest") would have accrued on the Outstanding Notes. Because the
Company determined that, when the Outstanding Notes were issued, there was only
a remote possibility that events would occur which would cause the Special
Interest to accrue on the Outstanding Notes, the Company determined that the
Special Interest should not be taken into account in concluding that the
Outstanding Notes were issued without original issue discount. The IRS could
disagree with this determination. Each U.S. Holder should consult his own tax
advisor with respect to the possible accrual of original issue discount on the
Outstanding Notes.

OPTIONAL REDEMPTION OR REPURCHASE

      The Outstanding Notes and the Exchange Notes are subject to (i) redemption
at the option of the Company, on or after September 15, 2000, at predetermined
redemption prices plus any accrued and unpaid interest, and (ii) repurchase at
the option of each Holder thereof upon the circumstances described under
"Description of the Exchange Notes -- Mandatory Redemption at the Option of
the Holders" at predetermined redemption prices plus any accrued and unpaid
interest. See "Description of the Exchange Notes." Upon the optional redemption
or repurchase of an Outstanding Note or an Exchange Note, it is expected that
the amount received by a Holder in excess of the Holder's adjusted tax basis in
the Outstanding Note or Exchange Note will be taxable as capital gain, if the
Outstanding Note or the Exchange Note is held as a capital asset (except to the
extent that such amount received is attributable to accrued but unpaid interest
or market discount, which will be treated as ordinary income).

PAYMENTS OF PRINCIPAL; DISPOSITIONS

      Upon the sale, exchange, redemption, retirement at maturity or other
disposition of an Outstanding Note or an Exchange Note, a U.S. Holder will
generally recognize taxable gain or loss equal to the difference between the sum
of cash plus the fair market value of all other property received on such
disposition (except to the extent such cash or property is attributable to
accrued but unpaid interest or market discount, which will be taxable as
ordinary income) and such U.S. Holder's adjusted tax basis in the Outstanding
Note or the Exchange Note. A U.S. Holder's adjusted tax basis in an Outstanding
Note or an Exchange Note generally will equal the cost of the Outstanding Note
or the Exchange Note to such U.S. Holder (increased for accrued original issue
discount, if any), less any principal payment received by such U.S. Holder. Gain
or loss realized by a U.S. Holder on the sale, redemption or other disposition
of an 

                                       97
<PAGE>
Outstanding Note or an Exchange Note generally will be long-term capital gain or
loss if, at the time of the disposition, the Outstanding Note or the Exchange
Note has been held for more than 18 months. Beginning after December 31, 2000, 
special capital gain rates may apply if the Outstanding Note or Exchange Note
has been held for more than five years.

AMORTIZABLE BOND PREMIUM

      If a U.S. Holder pays an amount (exclusive of accrued and unpaid interest
through the acquisition date) in excess of the Outstanding Note's or the
Exchange Note's stated redemption price at maturity at the time of its
acquisition ("Bond Premium"), the U.S. Holder will not be required to include
original issue discount, if any, in his income and may elect to amortize Bond
Premium. If Bond Premium is amortized, the amount of interest that must be
included in the U.S. Holder's income from each period ending on an interest
payment date or stated maturity, as the case may be, will be reduced by the
portion of the Bond Premium allocable to such period based on the Outstanding
Note's or the Exchange Note's yield to maturity and the U.S. Holder's adjusted
basis in the Outstanding Notes or the Exchange Notes will be reduced
accordingly. This election applies to all notes acquired by the U.S. Holder
during the year of election and thereafter.

MARKET DISCOUNT

      A U.S. Holder, other than an initial holder, will be treated as holding an
Outstanding Note or an Exchange Note at a market discount (a "Market Discount
Note") if the amount for which such U.S. Holder purchased the Outstanding Note
or the Exchange Note is less than the Outstanding Note's or the Exchange Note's,
respectively, stated redemption price at maturity, or, in the case of an
Outstanding Note issued with original issue discount, the "revised issue price,"
as defined in Section 1278 of the Code, subject in both cases to a de minimis
rule. An initial holder of an Outstanding Note will be treated as holding a
Market Discount Note if the initial holder purchased such Outstanding Note for
less than its issue price.

      In general, any partial payment of principal on, or gain recognized on the
maturity, optional redemption or repurchase, or disposition of, a Market
Discount Note will be treated as ordinary interest income to the extent of
accrued market discount on such Market Discount Note. Alternatively, a U.S.
Holder of a Market Discount Note may elect to include market discount in income
currently over the life of the Market Discount Note. Such an election applies to
all debt instruments with market discount acquired by the electing U.S. Holder
on or after the first day of the first taxable year to which the election
applies and may not be revoked without the consent of the IRS.

      Market discount accrues on a straight-line basis, unless the U.S. Holder
elects to accrue such discount on a constant yield to maturity basis. Such an
election is applicable only to the Market Discount Note with respect to which it
is made and is irrevocable. A U.S. Holder of a Market Discount Note that does
not elect to include market discount in income currently generally will be
required to defer deductions for interest on borrowings allocable to such Market
Discount Note, in an amount not exceeding the accrued market discount on such
Market Discount Note, until the maturity or disposition of such Market Discount
Note. If such Market Discount Note is disposed of in a non-taxable transaction
(other than a nonrecognition transaction described in Section 1276(c) of the
Code) accrued market discount will be includable as ordinary income to the U.S.
Holder as if such U.S. Holder had sold the Market Discount Note at its then fair
market value.

BACKUP WITHHOLDING

      Under the Code, a holder of an Outstanding Note or Exchange Note may be
subject, under certain circumstances, to "backup withholding" at a 31% rate with
respect to payments in respect of interest thereon or the gross proceeds from
the disposition thereof. This withholding generally applies only if the holder
(i) fails to furnish his or her social security or other taxpayer identification
number ("TIN") after request therefor, (ii) furnishes an incorrect TIN, (iii) is
notified by the IRS that he or she has failed to report properly payments of
interest and dividends and the IRS has notified the Company that he or she is

                                       98
<PAGE>
subject to backup withholding, or (iv) fails, under certain circumstances, to
provide a certified statement, signed under penalty of perjury, that the TIN
provided is his or her correct number and that he or she is not subject to
backup withholding. Any amount withheld from a payment to a holder under the
backup withholding rules is allowable as a credit against such holder's Federal
income tax liability, provided that the required information is furnished to the
IRS. Corporations, Non-U.S. Holders and certain other entities described in the
Code and Treasury regulations are generally exempt from such withholding if
their exempt status is properly established.

           DESCRIPTION OF OUTSTANDING SECURITIES AND DEBT INSTRUMENTS

COMMON STOCK

      The Company is authorized by its Charter to issue up to 20,000,000 shares
of Common Stock, $0.01 par value. As of June 30, 1997, 5,996,171 shares of
Common Stock were issued and outstanding.

      Holders of Common Stock are entitled to one vote per share in the election
of directors and on all other matters submitted to a vote of stockholders. Such
holders do not have the right to cumulate their votes in the election of
directors. Holders of Common Stock have no redemption or conversion rights and
no preemptive or other rights to subscribe for securities of the Company. In the
event of a liquidation, dissolution or winding up of the Company, holders of
Common Stock are entitled to share equally and ratably in all of the assets
remaining, if any, after satisfaction of all debts and liabilities of the
Company, and of the preferential rights of any series of preferred stock then
outstanding. The outstanding shares of Common Stock are validly issued, fully
paid and nonassessable. Holders of Common Stock are entitled to receive
dividends when, as and if declared by the Board of Directors out of funds
legally available therefor. American Stock Transfer & Trust Company is transfer
agent and registrar for the Common Stock.

PREFERRED STOCK

      The Company is authorized by its Charter to issue 2,500,000 shares of
preferred stock, $0.01 par value per share. The Board of Directors has the
authority to divide the preferred stock into one or more series and to fix and
determine the relative rights and preferences of the shares of each such series,
including dividend rates, terms of redemption, sinking funds, the amount payable
in the event of voluntary liquidation, dissolution or winding up of the affairs
of the Company, conversions rights and voting powers. The Company has authorized
the issuance of the Convertible Exchangeable Preferred Stock, Series A,
consisting of up to 1,380,000 shares of preferred stock ("Series A Preferred
Stock").

      SERIES A PREFERRED STOCK

      In November 1995, the Company issued and sold 1,315,500 shares of its
Series A Preferred Stock. The following description of the Series A Preferred
Stock is qualified in its entirety by the Certificate of Designations dated
November 22, 1995, a copy of which is filed as an exhibit to the Company's Form
10-K for fiscal year ended December 31, 1995.

      DIVIDEND RIGHTS. Holders of the Series A Preferred Stock are entitled to
an annual cash dividend of $2.125 per share, payable quarterly. If dividends are
not paid in full on all outstanding shares of the Series A Preferred Stock and
any other security ranking on parity with the Series A Preferred Stock,
dividends declared on the Series A Preferred Stock and such other parity stock
are paid pro rata. Unless full cumulative dividends on all outstanding shares of
Series A Preferred Stock have been paid, no dividends (other than in Common
Stock or other stock ranking junior to the Series A Preferred Stock) may be
paid, or any other distributions made, on the Common Stock or on any other stock
of the Company ranking junior to the Series A Preferred Stock, nor may any
Common Stock or any other stock of the Company ranking junior to or on a parity
with the Series A Preferred Stock be redeemed, purchased or

                                       99
<PAGE>
otherwise acquired for any consideration by the Company (except by conversion
into or exchange for stock of the Company ranking junior to the Series A
Preferred Stock).

      CONVERSION. The Series A Preferred Stock is convertible at any time prior
to being called for redemption into Common Stock at a rate of approximately
2.273 shares of Common Stock for each share of Series A Preferred Stock, subject
to adjustment for certain antidilutive events. The Company from time to time may
reduce the conversion price by any amount for a period of at least 20 days if
the Board of Directors determines that such reduction is in the best interests
of the Company. In the event of certain changes in control or fundamental
changes, holders of Series A Preferred Stock have the right to convert all of
their Series A Preferred Stock into Common Stock at a rate equal to the average
of the last reported sales prices of the Common Stock for the five business days
ending on the last business day preceding the date of the change in control or
fundamental change. The Company or its successor may elect to distribute cash to
such holders in lieu of Common Stock at an equal value.

      EXCHANGE. The Series A Preferred Stock may be exchanged at the option of
the Company for Convertible Debentures beginning on January 15, 1998 at the rate
of $25 principal amount of Convertible Debentures for each share of Preferred
Stock, provided that all accrued and unpaid dividends have been paid and certain
other conditions are met.
See "-- Convertible Debentures," below.

      REDEMPTION. On or after December 31, 1998 the Company may from time to
time redeem the Series A Preferred Stock at an initial redemption price of
$26.488. On December 31 of each year thereafter and until December 31, 2005, the
redemption price decreases. On December 31, 2005 and thereafter, the redemption
price shall remain at $25.

      VOTING RIGHTS. The holders of Series A Preferred Stock have no voting
rights, except as otherwise provided by law. However, if dividend payments are
in arrears in an amount equal to or exceeding six quarterly dividends, the
number of directors of the Company will be increased by two and the holders of
the Series A Preferred Stock (voting separately as a class) will be entitled to
elect the additional two directors until all dividends have been paid. In
addition, the Company may not create, issue or increase the authorized number of
shares of any class or series of stock ranking senior to the Series A Preferred
Stock or alter, change or repeal any of the powers, rights or preferences of the
holders of the Series A Preferred Stock as to adversely affect such powers,
rights or preferences.

CONVERTIBLE DEBENTURES

      The Company may, at its option, exchange its Convertible Debentures for
its Series A Preferred Stock. If issued, the Convertible Debentures will be
issued under an indenture between the Company and Bank One, Columbus, NA, as
trustee, a copy of which is filed as an exhibit to the Company's Form 10-K for
fiscal year 1996. The statements below are summaries of certain provisions of
such indenture and the Convertible Debentures, do not purport to be complete and
are qualified in their entirety by such reference.

      GENERAL. The Convertible Debentures will be unsecured, subordinated
obligations of the Company, limited in aggregate principal amount to the
aggregate liquidation preference of the Series A Preferred Stock and will mature
on December 31, 2010. The Company will pay interest on the Convertible
Debentures semiannually following the issue thereof at the rate of 8.5% per
annum. The Convertible Debentures are to be issued in fully registered form,
without coupons, in denominations of $25 or any integral multiple thereof.

      CONVERSION. The Convertible Debentures will be convertible at any time
after issue and prior to being called for redemption into Common Stock at the
conversion rate in effect on the Series A Preferred Stock at the date of
exchange, subject to adjustment for certain antidilutive events. The Company
from 

                                      100
<PAGE>
time to time may reduce the conversion price in order that certain stock-related
distributions which may be made by the Company to its shareholders will not be
taxable. Each holder of a Convertible Debenture will be entitled to conversion
rights identical in substance to the rights applicable to holders of Series A
Preferred Stock in the event of a change in control or fundamental change.

      SUBORDINATION Payment of principal of (and premium, if any) and interest
on the Convertible Debentures will be subordinated and junior in right of
payment to the prior payment in full of all senior indebtedness of the Company,
including the Notes. During the continuation of any default in the payment of
principal, interest or premium on any senior indebtedness, no payment with
respect to the principal, interest or premium (if any) on the Convertible
Debentures may be made until such default on the senior indebtedness shall have
been cured or waived or shall have ceased to exist.

      REDEMPTION On or after December 31, 1998, the Convertible Debentures may
be redeemed at the option of the Company at a redemption price (expressed as
percentages of principal amount) of 105.95%. On December 31 of each year
thereafter and until December 31, 2005, the redemption price decreases. On
December 31, 2005 and thereafter, the redemption price shall remain at 100.00%.

      EVENTS OF DEFAULT. Upon an Event of Default, the Trustee or the holders of
at least 25% in aggregate principal amount of the outstanding Convertible
Debentures may accelerate the maturity of all Convertible Debentures, subject to
certain conditions. An Event of Default is defined in the indenture generally as
(i) failure to pay principal or premium, if any, on any Convertible Debenture
when due at maturity, upon redemption or otherwise; (ii) failure to pay an
interest on any Convertible Debenture when due and continuing for 30 days; (iii)
breach of such indenture or Convertible Debentures by the Company; (iv) certain
events in bankruptcy, insolvency or reorganization; (v) default on indebtedness
(other than non-recourse indebtedness) resulting in more than $7,500,000
becoming due and payable prior to its maturity; or (vi) a judgment or decree
entered against the Company involving a liability of $7,500,000 or more.

CREDIT FACILITY

      Effective October 31, 1996, the Company amended and restated its Credit
Facility which is secured by mortgages covering substantially all of the
Company's producing oil and gas properties. The Credit Facility provides for
borrowings of a maximum of the lesser of $50 million and a Borrowing Base of $30
million which is adjusted periodically on the basis of a discounted present
value attributable to the Company's proven producing oil and gas reserves.
Pursuant to the Credit Facility, depending upon the percentage of the unused
portion of the Borrowing Base, the interest rate is equal to either Prime or
Prime plus 0.50%. Prime is the prime commercial lending rate announced from time
to time by the lender. The Company, at its option, may fix the interest rate on
all or a portion of the outstanding principal balance at either 1.00% or 1.375%
above an agreement-defined "Eurodollar" rate, depending upon the percentage of
the unused portion of the Borrowing Base, for periods of up to six months. The
weighted average interest rate for the total debt outstanding at June 30, 1997
was 6.70%. Under the Credit Facility, a commitment fee of .25% or .375% per
annum on the unused portion of the Borrowing Base (depending upon the percentage
of the unused portion of the Borrowing Base) is payable quarterly. The Company
may borrow, pay, reborrow and repay under the Credit Facility until October 31,
2000, on which date the Company must repay in full all amounts then outstanding.

      Borrowings under the Credit Facility are guaranteed by certain of the
Company's subsidiaries. The Credit Facility has certain customary covenants
including, but not limited to, covenants with respect to the following matters:
(i) limitation on restricted payments, distributions and investments; (ii)
limitations on guarantees and indebtedness; (iii) limitation on prepayments of
subordinated indebtedness; (iv) limitation on prepayments of additional
indebtedness; (v) limitation on mergers and issuances of securities; (vi)
limitation on sales of property; (vii) limitation on transactions with
affiliates; (viii) limitation on 

                                      101
<PAGE>
derivative contracts; (ix) limitation on acquisitions, new businesses and margin
stock; and (x) limitation with respect to certain prohibited types of contracts
and multi-employer ERISA plans. The Company is also required to maintain certain
financial ratios and conditions, including without limitation an EBITDA to debt
service coverage ratio, a net worth requirement and a funded debt to
capitalization ratio.

      EXISTING NOTES

      On November 24, 1996, the Company sold $24,150,000 aggregate principal
amount of 10% Senior Subordinated Notes due December 15, 2001 (the "Existing
Notes"). The following description of the Existing Notes is qualified in its
entirety by reference to the indenture for the Existing Notes ("Existing
Indenture"), a form of which is available upon request of the Company.
Capitalized terms have the meanings assigned to them in the Existing Indenture.

      Payments of principal, interest and premium, if any, under the Existing
Notes are subordinate to all existing and future Senior Indebtedness of the
Company and PARI PASSU with the Notes.

      The Existing Notes are not entitled to the benefit of mandatory sinking
fund payments. The Existing Notes are subject to redemption at any time on or
after December 15, 1997, at the option of the Company, at par plus accrued and
unpaid interest to the date fixed for redemption.

      The Existing Notes contain covenants substantially identical to the Notes.
See "Description of the Exchange Notes - Certain Covenants."

                              PLAN OF DISTRIBUTION

      Based on interpretations of the staff of the Division of Corporation
Finance of the Commission set forth in no- action letters issued to third
parties, the Company believes that, except as described below, Exchange Notes
issued pursuant to the Exchange Offer may be offered for resale, resold and
otherwise transferred by respective holders thereof (other than a holder who is
a broker-dealer) without further compliance with the registration and prospectus
delivery requirements of the Securities Act, provided that (i) such Exchange
Notes are acquired in the ordinary course of such holder's business and (ii)
such holder is not participating, and has no arrangement or understanding with
any person to participate in a distribution of the Exchange Notes. A holder of
Outstanding Notes that is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act or who intends to participate in the Exchange
Offer for the purpose of distributing Exchange Notes, or that is a broker-dealer
that purchased Outstanding Notes from the Company to resell pursuant to an
exemption from registration (a) cannot rely on such interpretations by the staff
of the Division of Corporation Finance of the Commission, (b) will not be
permitted or entitled to tender such Outstanding Notes in the Exchange Offer and
(c) must comply with the registration and prospectus delivery requirements of
the Securities Act in connection with any sale or transfer of such Outstanding
Notes. Any holder who tenders Outstanding Notes in the Exchange Offer with the
intention or for the purpose of participating in a distribution of the Exchange
Notes cannot rely on such interpretation by the staff of the Commission and must
comply with the registration and prospectus delivery requirements of the
Securities Act in connection with a secondary resale transaction. Unless an
exemption from registration is otherwise available, any such resale transaction
should be covered by an effective registration statement containing selling
security holders information required by Item 507 of Regulation S-K under the
Securities Act. To date, the staff of the Commission has taken the position that
a broker-dealer that has acquired securities in exchange for securities that
were acquired by such broker-dealer as a result of market making activities or
other trading activities (a "Participating Broker-Dealer") may fulfill its
prospectus delivery requirements with the prospectus contained in an exchange
offer registration statement.

                                      102
<PAGE>
      Each holder of Outstanding Notes who wishes to exchange its Outstanding
Notes for Exchange Notes in the Exchange Offer will be required to make certain
representations to the Company set forth in "The Exchange Offer -- Procedures
for Tendering."

      Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Notes. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of Exchange Notes received in exchange for Outstanding Notes where
such Outstanding Notes were acquired as a result of market-making activities or
other trading activities. The Company has agreed that, starting on the
Expiration Date and ending on the close of business on the forty-fifth day after
the Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale.

      The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through brokers or dealers who may
receive compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit from any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that by acknowledging that it will deliver
and by delivering a prospectus meeting the requirements of the Securities Act, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

      For a period of forty-five days after the Expiration Date, the Company
will promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to indemnify the holders of
the Outstanding Notes (including any broker-dealers) against certain
liabilities, including liabilities under the Securities Act.

                                  LEGAL MATTERS

      The validity of the Exchange Notes will be passed upon by Butler & Binion,
L.L.P., Houston, Texas.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of Callon Petroleum Company:

      We have audited the accompanying consolidated balance sheets of Callon
Petroleum Company (a Delaware corporation) and subsidiaries as of December 31,
1996 and 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended December 31, 1996. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Callon Petroleum Company and
subsidiaries, as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

partnership between CPOC and NOCO Enterprises, L. P. ("NOCO"), a limited
partnership owned by private investors (CPOC, CCP and CN are referred to
collectively as the "Constituent Entities"). The combination of the businesses
and properties of the Constituent Entities with the Company was effected in
three simultaneous transactions on September 16, 1994 (collectively, the
"Consolidation"):

            (i) CCP was merged (the "Merger") into the Company and each unit of
      limited partner interest in CCP ("Units") was converted into the right to
      receive one-third of a share of Common Stock of the Company ("Common
      Stock"). Subject to compliance with certain requirements, any holder of
      less than 100 Units could elect to receive, in lieu of shares of Common
      Stock, $4.50 in cash per Unit owned. CCP unitholders received 1,877,493
      shares of Common Stock of the Company.

            (ii) Holders of capital stock of CPOC exchanged such capital stock
      for an aggregate of 1,892,278 shares of Common Stock of the Company,
      resulting in CPOC becoming a wholly owned subsidiary of the Company (the
      "Share Exchange").

            (iii) NOCO exchanged its partner interest for 1,984,758 shares of
      Common Stock of the Company, resulting in CN becoming directly and
      indirectly wholly owned by the Company (the "CN Exchange"). See Note 4.

As a result of the Consolidation, all of the businesses and properties of the
Constituent Entities are owned (directly or indirectly) by the Company, and the
former stockholders of CPOC, partners of CCP and NOCO have become stockholders
of the Company. Certain registration rights were granted to the holders of the
capital stock of CPOC and NOCO. See Note 7.

The Company and its predecessors have been engaged in the acquisition,
development and exploration of crude oil and natural gas since 1950. The
Company's properties are geographically concentrated in Louisiana, Alabama and
offshore Gulf of Mexico.


BASIS OF PRESENTATION

The accompanying Consolidated Financial Statements of the Company reflect the
combination of CPOC, CCP, and CPOC's interest in CN as a reorganization of
entities under common control (accounted for similar to a "pooling of
interest"). NOCO's interest in CN was recorded as a purchase effective at the
date of the Consolidation (September 16, 1994), thus amounts related to the CN
Exchange are included from the date of the purchase for the periods presented in
the Consolidated Financial Statements. CPOC made no direct investment in CN,
therefore the inclusion of 100% of the assets and liabilities of CN in the
Consolidated Balance Sheet, as of the purchase date, are attributable to NOCO's
interest in CN. Because 

                                      F-7
<PAGE>
no revenues or expenses, as of the date of the Consolidation, were attributable
to CPOC's interest in CN until NOCO had received a preferential return on its
investment, all of the revenues and expenses of CN through September 16, 1994,
are also attributable to NOCO. See Note 4 for pro forma information.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION AND REPORTING

The Consolidated Financial Statements include the accounts of the Company, and
its subsidiary, CPOC. CPOC also has subsidiaries which are Callon Offshore
Production, Inc., Mississippi Marketing, Inc. and Callon Exploration Company.
All intercompany accounts and transactions have been eliminated. Certain prior
year amounts have been reclassified to conform to presentation in the current
year.

USE OF ESTIMATES

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

ACCOUNTING PRONOUNCEMENTS

In March 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121 ("FAS 121"), "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of".
FAS 121 was adopted by the Company on January 1, 1996. The effect of adopting
FAS 121 was not material to the Company's financial position or results of
operations.

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123 ("FAS 123"), "Accounting for Stock-Based
Compensation", effective for the Company at December 31, 1996. Under FAS 123,
companies can either record expenses based on the fair value of stock-based
compensation upon issuance or elect to remain under the current "APB Opinion No.
25" method, whereby no compensation cost is recognized upon grant, and make
disclosures as if FAS 123 had been applied. The Company will continue to account
for its stock-based compensation plans under APB Opinion No. 25. See Note 10.

In June 1997, the Financial Accounting Standard Board issued Statement No. 130
("FAS 130"), "Reporting Comprehensive Income". FAS 130 establishes standards for
reporting and display of comprehensive income and its components in a full set
of general purpose financial statements. FAS 130 is effective for fiscal years
ending after December 15, 1997. The Company intends to comply with the
provisions of FAS 130.

PROPERTY AND EQUIPMENT

The Company follows the full cost method of accounting for oil and gas
properties whereby all costs incurred in connection with the acquisition,
exploration and development of oil and gas reserves, including certain overhead
costs, are capitalized. Such amounts include the cost of drilling and equipping
productive wells, dry hole costs, lease acquisition costs, delay rentals,
interest capitalized on unevaluated leases and other costs related to
exploration and development activities. Payroll and general and administrative
costs include salaries and related fringe benefits paid to employees directly
engaged in the acquisition, exploration and/or development of oil and gas
properties as well as other directly identifiable general and administrative
costs associated with such activities. Costs associated with unevaluated
properties are excluded from amortization. Unevaluated property costs are
transferred to evaluated 

                                      F-8
<PAGE>
property costs at such time as wells are completed on the properties, the
properties are sold or management determines these costs have been impaired.

Costs of properties, including future development and net future site
restoration, dismantlement and abandonment costs, which have proved reserves and
those which have been determined to be worthless, are depleted using the
unit-of-production method based on proved reserves. If the total capitalized
costs of oil and gas properties, net of amortization, exceed the sum of (1) the
estimated future net revenues from proved reserves at current prices and
discounted at 10% and (2) the cost of unevaluated properties (the full cost
ceiling amount), then such excess is charged to expense during the period in
which the excess occurs.

Upon the acquisition or discovery of oil and gas properties, management
estimates the future net costs to be incurred to dismantle, abandon and restore
the property using geological, engineering and regulatory data available. Such
cost estimates are periodically updated for changes in conditions and
requirements. Such estimated amounts are considered as part of the full cost
pool subject to amortization upon acquisition or discovery. Such costs are
capitalized as oil and gas properties as the actual restoration, dismantlement
and abandonment activities take place. As of June 30, 1997, December 31, 1996
and 1995, estimated future site restoration, dismantlement and abandonment
costs, net of related salvage value and amounts funded by abandonment trusts
(see Notes 7 and 9), were not material.

Depreciation of other property and equipment is provided using the straight-line
method over estimated lives of three to twenty years. Depreciation of the
pipeline facilities is provided using the straight-line method over a 27 year
estimated life.

NATURAL GAS IMBALANCES

The Company follows an entitlement method of accounting for its proportionate
share of gas production on a well by well basis, recording a receivable to the
extent that a well is in an "undertake" position and conversely recording a
liability to the extent that a well is in an "overtake" position.

DERIVATIVES

The Company uses derivative financial instruments (see Note 6) for price
protection purposes on a limited amount of its future production, and does not
use them for trading purposes. Such derivatives are accounted for on an accrual
basis and amounts paid or received under the agreements are recognized as oil
and gas sales in the period in which they accrue.

RESERVE FOR DOUBTFUL ACCOUNTS

The balance in the reserve for doubtful accounts included in accounts receivable
is $374,000, $393,000 and $481,000 at June 30, 1997, December 31, 1996 and 1995
respectively. Net charge offs were $88,000 and $181,000 in 1996 and 1994 and net
recoveries were $2,000 in 1995. There were no provisions to expense in the three
year period ended December 31, 1996 or the six months ended June 30, 1997. Net
charge offs were $2,000 and $88,000 for the six months ended June 30, 1997 and
1996, respectively.

STATEMENTS OF CASH FLOWS

For purposes of the Consolidated Statements of Cash Flows, the Company considers
all highly liquid investments purchased with an original maturity of three
months or less to be cash equivalents.

The Company paid no federal income taxes for the three years ended December 31,
1996. During the years ended December 31, 1996, 1995 and 1994, the Company made
cash payments of $250,807, $1,910,000 and $377,000, respectively, for interest
charged on its indebtedness, and $1,337,000 for the six months ended June 30,
1997.

                                      F-9
<PAGE>
PER SHARE AMOUNTS

Per share amounts are calculated on a weighted average basis in accordance with
the common shares issued in the Consolidation described in Note 1, adjusted for
the effect of stock options considered common stock equivalents computed using
the treasury stock method.

Fully diluted earnings per share for the six months ended June 30, 1997 was
calculated assuming the conversion of the Company's preferred stock into common
stock. The preferred stock was not included in prior calculations due to their
antidilutive effect on fully diluted earnings per share.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128 ("FAS 128"), "Earnings Per Share", which simplifies the computation of
earnings per share. FAS 128 is effective for financial statements issued for
periods ending after December 15, 1997 and requires restatement for all prior
period earnings per share data presented. Accordingly, basic earnings per share
and diluted earnings per share calculated in accordance with FAS 128 were $0.58
and $0.52 per share, respectively, for the first six months of 1997 and $0.15
and $0.15 per share, respectively, for the first six months of 1996.

Also in early 1997, the Financial Accounting Standards Board issued Statement
No. 129 ("FAS 129"). "Disclosure of Information about Capital Structure"
effective for financial statements issued for periods ending after December 15,
1997. The Company believes it is in compliance with the provisions of this
statement.

FAIR VALUE OF  FINANCIAL INSTRUMENTS

Fair value of cash, cash equivalents, accounts receivable, accounts payable and
long-term debt approximate book value at June 30, 1997 and December 31, 1996.
Fair value of long-term debt (specifically the 10% senior subordinated notes) is
based on quoted market value.

3.  INCOME TAXES

The Company follows the asset and liability method of accounting for deferred
income taxes prescribed by Financial Accounting Standards Board Statement No.
109 ("FAS 109") "Accounting for Income Taxes". The statement provides for the
recognition of a deferred tax asset for deductible temporary timing differences,
capital and operating loss carryforwards, statutory depletion carryforward and
tax credit carryforwards, net of a "valuation allowance". The valuation
allowance is provided for that portion of the asset, for which it is deemed more
likely than not, that it will not be realized. Accordingly, the Company has
recorded a deferred tax asset at December 31, 1996, 1995 and 1994 as follows:

<PAGE>
At December 31, 1996, the Company had, for tax reporting purposes, operating
loss carryforwards ("NOL") of $9.8 million which expire in 2000 through 2011.
Approximately $4.7 million of such carryovers are subject to limitations on
utilization as a result of ownership changes which occurred in CPOC's common
stock prior to the Consolidation and ownership changes as a result of the
Consolidation. Additionally, the Company had available for tax reporting
purposes $11.7 million in statutory depletion deductions which can be carried
forward for an indefinite period.

The provision for income taxes at the Company's effective tax rate differed from
the provision for income taxes at the statutory rate as follows:

4.  ACQUISITIONS

On September 14, 1994, (with an effective date of September 16, 1994) the
unitholders of CCP, stockholders of CPOC, and the partners of CN completed the
Consolidation as described in Note 1. Net assets purchased (excluding cash of
$3,989,000) was $13,847,000 of which oil and gas property, including pipeline
facilities, and debt amounted to $24,506,000 and $11,436,000, respectively. Such
amounts represent non-cash transactions and therefore are not included in the
Consolidated Statements of Cash Flows.

On December 29, 1995, CPOC purchased a 66.67% working interest in Chandeleur
Block 40 (the "CB 40 Acquisition") from Amerada Hess Corporation and, in a
simultaneous transaction under a pre-existing agreement, sold one-third of the
acquired interest to an industry partner. The Company's net purchase price of $6
million was funded from existing cash on hand.

The following information represents unaudited pro forma results of the Company
for the years ended December 31, 1995 and 1994 and includes both the purchase of
CN and the CB 40 Acquisition, presented as if the purchase of CN had occurred at
the beginning of 1994 and the CB 40 Acquisition presented as if it had occurred
at the beginning of 1995 and 1994.

addition to the shares of the Company issued in the CN Exchange.

The Company, together with an industry partner, was the high bidder on 12
offshore tracts at the Outer Continental Shelf ("OCS") Lease Sale #157, held
April 24, 1996 in New Orleans, Louisiana, and conducted by the U. S. Department
of the Interior through its Minerals Management Service ("MMS"). The Company
holds a 25% working interest in the leases and its share of the total lease
costs was approximately $11.4 million.

On September 25, 1996, the Company and the same industry partner submitted bids
and were awarded six additional offshore leases at the OCS Lease Sale #161, held
in New Orleans, Louisiana by the MMS. The Company's share of the costs was $3.8
million.
The Company owns a 25% working interest in the leases.

On June 26, 1997 the Company purchased an 18.8% working interest in Mobile Area
Blocks 863 and 907 and a 35% working interest in Mobile Area Block 908 from Elf
Exploration, Inc. The Company's net purchase price of approximately $11.8
million was funded from the Company's credit facility.

5.  LONG-TERM DEBT

Long-term Debt consisted of the following at:

Effective October 31, 1996, the Company entered into a new Credit Facility with
Chase Manhattan Bank. Borrowings under the Credit Facility are secured by
mortgages covering substantially all of the Company's producing oil and gas
properties. The Credit Facility provides for borrowings of a maximum of the
lesser of $50 million or a $30 million borrowing base ("Borrowing Base") which
is adjusted periodically on the basis of a discounted present value of future
net cash flows attributable to the Company's proved producing oil and gas
reserves. Pursuant to the Credit Facility, depending upon the percentage of the
unused portion of the Borrowing Base, the interest rate is equal to either the
lender's prime rate or the lender's prime rate plus 0.50%. The Company, at its
option, may fix the interest rate on all or a portion of the outstanding
principal balance at either 1.00% or 1.375% above a defined "Eurodollar" rate,
depending upon the percentage of the unused portion of the Borrowing Base, for
periods of up to six months. The weighted average interest rate for the total
debt outstanding at June 30, 1997 and December 31, 1996 was 6.70% and 8.25%,
respectively. Under the Credit Facility, a commitment fee of .25% or .375% per
annum on the unused portion of the Borrowing Base (depending upon the percentage
of the unused portion of the Borrowing Base) is payable quarterly. The Company
may borrow, pay, reborrow and repay under the Credit Facility until October 31,
2000, on which date, the Company must repay in full all amounts then
outstanding.

On November 27, 1996, the Company issued $24,150,000 of 10% Senior Subordinated
Notes that will mature December 15, 2001. The Company used the proceeds to
reduce borrowings under the Credit Facility and for other corporate purposes.
Interest is payable quarterly beginning March 15, 1997. The notes are redeemable
at the option of the Company, in whole or in part, on or after December 15,
1997, at 

                                      F-12
<PAGE>
100% of the principal amount thereof, plus accrued interest to the redemption
date. The notes are general unsecured obligations of the Company, subordinated
in right of payment to all existing and future indebtedness of the Company.

On July 31, 1997 the Company issued $36,000,000 of 10.125% Senior Subordinated
Notes due 2002. Interest is payable quarterly beginning September 15, 1997. The
Senior Subordinated Notes were offered pursuant to a Rule 144A transaction or an
applicable exemption from registration requirements. The net proceeds to the
Company, after costs of the transaction, were used to repay the outstanding
balance on Callon's Credit Facility and will fund a portion of the remaining
capital expenditure budget.

The Credit Facility and the subordinated debt contain various covenants
including restrictions on additional indebtedness and payment of cash dividends
as well as maintenance of certain financial ratios. This Company is in
compliance with these covenants at June 30, 1997.

6.  HEDGING CONTRACTS

The Company hedges with third parties certain of its crude oil and natural gas
production in various swap agreement contracts. The contracts are tied to
published market prices for crude oil and natural gas and are settled monthly
based on the differences between contract prices and the average defined market
price for that month applied to the related contract volume. The Company had no
open forward sales position related to this type of contract as of December 31,
1996 and June 30, 1997.

As of June 30, 1997, the Company entered into an agreement with third parties
whereby the Company purchased a put option guaranteeing the Company $1.80 per
MMBtu for gas volumes of 500,000 MMBtu per month from May 1997 through September
1997. Also, at June 30, 1997 the Company had outstanding a call option for
250,000 Mcf per month from December 1997 through February 1998 at $3.00 per Mcf.

As of December 31, 1996, the Company has open collar contracts with third
parties whereby minimum floor prices and maximum ceiling prices are contracted
and applied to related contract volumes. These agreements in effect for 1997 are
for average oil volumes of 15,000 barrels per month at (on average) a ceiling
price of $23.33 and floor of $18.00 and for average gas volumes of 583,000 Mcf
per month in the first quarter of 1997 at (on average) a ceiling price of $3.36
and floor of $2.88. As of June 30, 1997, oil contracts averaged volumes of
10,000 barrels per month at (on average) a ceiling of $24.00 and a floor of
$18.00 through 1997. Gas contracts included gas volumes of 34,444 Mcf per month
at (on average) a ceiling price of $2.66 and a floor of $2.00 through March
1998.

During 1994, the Company recognized revenue under swap agreements of $1,227,000
and $1,724,000 on Historical and Pro forma basis respectively, and $2,466,000
for the twelve months ended December 31, 1995. The Company recognized a
reduction in revenue of $2,757,195 for the year ended December 31, 1996 under
all contracts. During the first six months of 1997, the Company recognized an
increase in revenues of $451,675 for all contracts.

The calculation of the fair market value of the outstanding contracts as of
December 31, 1996 indicates a $308,400 market value benefit to the Company based
on market prices at that date. As of June 30, 1997 the calculation of the fair
market value of the outstanding contracts indicates a $60,169 market value
benefit to the Company based on market prices at that date.

7.  COMMITMENTS AND CONTINGENCIES

As described in Note 9, abandonment trusts (the "Trusts") have been established
for future abandonment obligations of those oil and gas properties of the
Company burdened by a net profits interest. The management of the Company
believes the Trusts will be sufficient to offset those future abandonment
liabilities; however, the Company is responsible for any abandonment expenses in
excess of the Trusts' balances. As of December 31, 1996, total estimated site
restoration, dismantlement and abandonment 

                                      F-13
<PAGE>
costs were approximately $23,000,000, net of expected salvage value.
Substantially all such costs are expected to be funded through the Trusts'
funds, all of which will be accessible to the Company when abandonment work
begins. In addition as a working interest owner and/or operator of oil and gas
properties, the Company is responsible for the cost of abandonment of such
properties. See Note 2.

Also, as part of the Consolidation, the Company entered into Registration Rights
Agreements whereby the former stockholders of CPOC and NOCO are entitled to
require the Company to register Common Stock of the Company owned by them with
the Securities and Exchange Commission for sale to the public in a firm
commitment public offering and generally to include shares owned by them, at no
cost, in registration statements filed by the Company. Costs of the offering
will not include discounts and commissions, which will be paid by the respective
sellers of the Common Stock.

Depreciation, depletion and amortization per unit-of-production (equivalent
barrel of oil) amounted to $5.87, $5.95, and $5.80 for the years ended December
31, 1996, 1995 and 1994, respectively, and $5.66 and $6.02 for the six months
ended June 30, 1997 and 1996, respectively.

9.  NET PROFITS INTEREST

Since 1989, the Constituent Entities have entered into separate agreements to
purchase certain oil and gas properties with gross contract acquisition price of
$170,000,000 ($150,000,000 net as of closing dates) 

                                      F-14
<PAGE>
and, in simultaneous transactions, entered into agreements to sell overriding
royalty interests ("ORRI") in the acquired properties. These ORRI are in the
form of net profits interests ("NPI") equal to a significant percentage of the
excess of gross proceeds over production costs, as defined, from the acquired
oil and gas properties. A net deficit incurred in any month can be carried
forward to subsequent months until such deficit is fully recovered. The Company
has the right to abandon the purchased oil and gas properties if it deems the
properties to be uneconomical.

The Company has, pursuant to the purchase agreements, created abandonment trusts
whereby funds are provided out of gross production proceeds from the properties
for the estimated amount of future abandonment obligations related to the
working interests owned by the Company. The Trusts are administered by unrelated
third party trustees for the benefit of the Company's working interest in each
property. The Trust agreements limit their funds to be disbursed for the
satisfaction of abandonment obligations. Any funds remaining in the Trusts after
all restoration, dismantlement and abandonment obligations have been met will be
distributed to the owners of the properties in the same ratio as contributions
to the Trusts. The Trusts' assets are excluded from the Consolidated Balance
Sheets of the Company because the Company does not control the Trusts. Estimated
future revenues and costs associated with the NPI and the Trusts are also
excluded from the oil and gas reserve disclosures at Note 12. As of June 30,
1997, December 31, 1996 and 1995 the Trusts' assets (all cash and investments)
totaled $18,200,000, $18,200,000 and $16,100,000, respectively, all of which
will be available to the Company to pay its portion, as working interest owner,
of the restoration, dismantlement and abandonment costs discussed at Note 7.

At the time of acquisition of properties by the Company, the property owners
estimated the future costs to be incurred for site restoration, dismantlement
and abandonment, net of salvage value. A portion of the amounts necessary to pay
such estimated costs was deposited in the Trusts upon acquisition of the
properties, and the remainder is deposited from time to time out of the proceeds
from production. The determination of the amount deposited upon the acquisition
of the properties and the amount to be deposited as proceeds from production was
based on numerous factors, including the estimated reserves of the properties.
The amounts deposited in the Trusts upon acquisition of the properties were
capitalized by the Company as oil and gas properties.

As operator, the Company receives all of the revenues and incurs all of the
production costs for the purchased oil and gas properties but retains only that
portion applicable to its net ownership share. As a result, the payables and
receivables associated with operating the properties included in the Company's
Consolidated Balance Sheets include both the Company's and all other outside
owners' shares. However, revenues and production costs associated with the
acquired properties reflected in the accompanying Consolidated Statements of
Operations represent only the Company's share, after reduction for the NPI. At
June 30, 1997, December 31, 1996 and 1995 the amounts payable to the NPI owners
included in the accounts payable in the accompanying Consolidated Balance Sheets
were approximately $3,900,000, $5,400,000 and $2,800,000, respectively.

10.  EMPLOYEE BENEFIT PLANS

The Company has adopted a series of incentive compensation plans designed to
align the interest of the executives and employees with those of its
stockholders. The following is a brief description of each plan:

- -     The Savings and Protection Plan provides employees with the option to
defer receipt of a portion of their compensation and the Company may, at its
discretion, match a portion of the employee's deferral with cash and Company
Common Stock. The Company may also elect, at its discretion, to contribute a
non-matching amount in cash and Company Common Stock to employees. The amounts
held under the Savings and Protection Plan are invested in various funds
maintained by a third party in accordance with the directions of each employee.
An employee is fully vested immediately upon participation in the Savings and
Protection Plan. The total amounts contributed by the Company, including the
value of the 

                                      F-15
<PAGE>
common stock contributed, were $241,000, $176,000 and $154,000 in the years
1996, 1995 and 1994, respectively.

- -     The 1994 Stock Incentive Plan (the "1994 Plan") provides for 600,000
shares of Common Stock to be reserved for issuance pursuant to such plan. Under
the 1994 Plan the Company may grant both stock options qualifying under Section
422 of the Internal Revenue Code and options that are not qualified as incentive
stock options, as well as performance shares. No options will be granted at an
exercise price of less than fair market value of the Common Stock on the date of
grant. A total of 500,000 options are outstanding and all such options could be
exercised as of December 31, 1996. These options have an expiration date 10
years from date of grant.

- -     On August 23, 1996, the Board of Directors of the Company approved and
adopted the Callon Petroleum Company 1996 Stock Incentive Plan (the "1996
Plan"). The 1996 Plan provides for the same types of awards as the 1994 Plan and
is limited to a maximum of 900,000 shares of common stock that may be subject to
outstanding awards. The Company granted stock options to purchase an aggregate
530,000 shares of Common Stock under the plan, subject to stockholder approval
of the 1996 Plan. All of such options were granted at an exercise price of $12
per share, the fair market value of the Common Stock on the date of grant. Terms
of the plan for 450,000 options provide that 20% of the options become
exercisable on January 1 of each succeeding year, beginning January 1, 1997.
Non-employee director options aggregating 80,000 shares vest 25% at each
succeeding annual meeting of directors following each annual stockholders'
meeting, beginning in 1997. Unvested options are subject to forfeiture upon
certain termination of employment events and expire 10 years from date of grant.

The Company accounts for the options issued pursuant to the stock incentive
plans under APB Opinion No. 25, under which no compensation cost has been
recognized (see Note 2). Had compensation cost for these plans been determined
consistent with FAS 123, the Company's net income and earnings per common share
would have been reduced to the following pro forma amounts:

                                                 YEAR ENDED DECEMBER 31,

Because the Statement 123 method of accounting has not been applied to options
granted prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

A summary of the status of the Company's two stock option plans at December 31,
1996, 1995 and 1994 and changes during the years then ended is presented in the

The Company also awarded 225,000 performance shares under the 1996 Plan to the
Company's Executive officers on August 23, 1996. All of the performance shares
granted will vest in whole on January 1, 2001, and will be subject to forfeiture
upon certain termination of employment events. Approximately $208,000 of
compensation cost was charged to expense in 1996 related to the performance
shares granted.

The Company has no other formal benefit plans.

11.  PREFERRED STOCK

In November 1995, the Company sold 1,315,500 shares of $2.125 Convertible
Exchangeable Preferred Stock, Series A (the "Preferred Stock"). Annual dividends
are $2.125 per share and are cumulative. The net proceeds of the $.01 par value
stock after underwriters discount and expense was $30,899,000. Each share has a
liquidation preference of $25.00, plus accrued and unpaid dividends. Dividends
on the Preferred Stock are cumulative from the date of issuance and are payable
quarterly, commencing January 15, 1996. The Preferred Stock is convertible at
any time, at the option of the holders thereof, unless previously redeemed, into
shares of Common Stock of the Company at an initial conversion price of $11 per
share of Common Stock, subject to adjustments under certain conditions.

The Preferred Stock is redeemable at any time on or after December 31, 1998, in
whole or in part at the option of the Company at a redemption price of $26.488
per share beginning at December 31, 1998 and at premiums declining to the $25.00
liquidation preference by the year 2005 and thereafter, plus accrued and 

                                      F-17
<PAGE>
unpaid dividends. The Preferred Stock is also exchangeable, in whole, but not in
part, at the option of the Company on or after January 15, 1998 for the
Company's 8.5% Convertible Subordinated Debentures due 2010 (the "Debentures")
at a rate of $25.00 principal amount of Debentures for each share of Preferred
Stock. The Debentures will be convertible into Common Stock of the Company on
the same terms as the Preferred Stock and will pay interest semi-annually.

The Company used approximately $21.5 million of the net proceeds from the sale
of the Preferred Stock to repay outstanding indebtedness under its primary
credit facility (See Note 5), which indebtedness was incurred to finance certain
acquisitions of properties. The Company is using the excess of the net proceeds
from the sale of the Preferred Stock over the amount used to repay indebtedness,
together with internally generated cash flows to acquire, develop and explore
oil and gas properties.

12.  SUPPLEMENTAL OIL AND GAS RESERVE DATA (UNAUDITED)

The Company's proved oil and gas reserves at December 31, 1996, 1995 and 1994
have been estimated by independent petroleum consultants in accordance with
guidelines established by the Securities and Exchange Commission ("SEC").
Accordingly, the following reserve estimates are based upon existing economic
and operating conditions.

There are numerous uncertainties inherent in establishing quantities of proved
reserves. The following reserve data represent estimates only and should not be
construed as being exact. In addition, the present values should not be
construed as the current market value of the Company's oil and gas properties or
the cost that would be incurred to obtain equivalent reserves.

ESTIMATED RESERVES

Changes in the estimated net quantities of crude oil and natural gas reserves,
all of which are located onshore and offshore in the continental United States,
are as follows:

STANDARDIZED MEASURE

The following tables present the Company's standardized measure of discounted
future net cash flows and changes therein relating to proved oil and gas
reserves and were computed using reserve valuations based on regulations
prescribed by the SEC. These regulations provide that the oil, condensate and
gas price structure utilized to project future net cash flows reflects current
prices at each date presented and have been escalated only when known and
determinable price changes are provided by contract and law. Future production,
development and net abandonment costs are based on current costs without
escalation. In 1995 and 1994, no future income taxes were provided on the future
net inflows as tax credits (including carryovers) and other permanent
differences were expected to be higher than the estimated future income taxes
calculated using the appropriate statutory rates. The resulting net future cash
flows have been discounted to their present values based on a 10% annual
discount factor.

            NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

1.    BASIS OF PRESENTATION

      On June 26, 1997, Callon Petroleum Operating Company, a wholly owned
subsidiary of Callon Petroleum Company (the "Company"), purchased an 18.8%
working interest in the Mobile Area Block 864 Unit from Elf Exploration, Inc.
(the "MAB 864 Acquisition"). The Company's net purchase price of $11.8 million
was funded from the credit facility of the Company.

      The accompanying Pro Forma Consolidated Statements of Operations of the
Company for the year ended December 31, 1996 and the six months ended June 30,
1997 give effect to the purchase of the MAB 864 Acquisition as if the
transaction occurred at the beginning of each of the periods presented.

      The Pro Forma Consolidated Statements of Operations are based on the
assumptions set forth in the Notes to such statements. Such pro forma
information should be read in conjunction with the related financial information
of the Company and is not necessarily indicative of the results which would
actually have occurred had the transaction been in effect on the date or for the
period indicated or which may occur in the future.

2.    PRO FORMA ADJUSTMENTS

      Pro Forma entries necessary to adjust the historical financial statements
of the Company are as follows:

      (a)   To reflect the purchase of the MAB 864 Acquisition and the related
            results of operations as described in Note 1.

      (b)   Reflects an increase of interest expense related to the purchase of
            the MAB 864 Acquisition as if the transaction had occurred at the
            beginning of the periods for the year ended December 31, 1996 and
            for the six months ended June 30, 1997. The interest rate used was
            8.25%. A one-eighth change in this estimated rate would affect
            interest expense by $17,200 and $3,900 for the year ended December
            31, 1996 and the six months ended June 30, 1997, respectively.

      (c)   To record a provision for Federal income taxes at a corporate
            statutory rate of 35% on pro forma income as a result of the
            acquisition.

      (d)   To adjust  depletion  for the combined full cost pool based on the 
            purchase of the MAB 864 Acquisition as described in Note 1.

                         Report of Independent Auditors

Stockholders and Board of Directors
Callon Petroleum Company

We have audited the accompanying statement of revenues and direct operating
expenses of the working interest in Mobile Area Block 864 Unit (the "Property")
acquired by Callon Petroleum Operating Company (the "Company"), a wholly owned
subsidiary of Callon Petroleum Company, from Elf Exploration, Inc. (see Note 1
to the accompanying statement) for the year ended December 31, 1996. This
statement is the responsibility of the Company's management. Our responsibility
is to express an opinion on this statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the statement of revenues and direct operating expenses
is free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the statement of revenues and
direct operating expenses. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall statement presentation. We believe that our audit
provides a reasonable basis for our opinion.

The accompanying statement of revenues and direct operating expenses was
prepared for the purpose of complying with the rules and regulations of the
Securities and Exchange Commission and is not intended to be a complete
presentation of revenues and expenses of the Property.

In our opinion, the statement of revenues and direct operating expenses referred
to above presents fairly, in all material respects, the revenues and direct
operating expenses of the Property for the year ended December 31, 1996, in
conformity with generally accepted accounting principles.

1. BASIS OF PRESENTATION

Callon Petroleum Operating Company (the "Company"), a wholly owned subsidiary of
Callon Petroleum Company, acquired a working interest in Mobile Area Block 864
Unit (the "Property") from Elf Exploration, Inc. (the "Seller"). The closing
date of the acquisition was June 26, 1997, and the net purchase price was $11.8
million.

The accompanying statement of revenues and direct operating expenses, which is
prepared on the accrual basis of accounting, relates only to the working
interest in the producing oil and gas property acquired and may not be
representative of future operations. The statement includes revenues and direct
operating expenses, including production and ad valorem taxes, for the entire
period presented. The statement does not include federal and state income taxes,
interest, depletion, depreciation and amortization, or general and
administrative expenses because such amounts would not be indicative of those
expenses which would be incurred by the Company. Presentation of complete
historical financial statements for the year ended December 31, 1996 and the six
months ended June 30, 1997 is not practicable because the Property was not
accounted for as a separate entity; therefore, such statements are not
available.

Revenues in the accompanying statement of revenues and direct operating expenses
are recognized on the entitlement method.

The preparation of the statement of revenues and direct operating expenses in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported in the statement
and accompanying notes. Actual results could differ from those estimates.

The unaudited statement of revenues and direct operating expenses for the
six-month period ended June 30, 1997, in the opinion of management, was prepared
on a basis consistent with the audited statement of revenues and direct
operating expenses and includes all adjustments necessary to present fairly the
results of the period.

2. SUPPLEMENTAL INFORMATION ON OIL AND GAS RESERVES (UNAUDITED)

There are numerous uncertainties inherent in estimating quantities of proved
reserves and in projecting the future rates of production and timing of
development expenditures. Therefore, actual production, revenues, and
development and operating expenses may not occur as estimated. The reserve data
are estimates only, are subject to many uncertainties, and are based on data
gained from production histories and on assumptions as to geologic formations
and other matters. Actual quantities may differ materially from the amounts
estimated.

The following reserve data, prepared by the Company, represents estimates of
proved natural gas reserves of the Property, which is located in the United
States. There are no oil reserves associated with the Property.

The estimated standardized measure of discounted future net cash flows relating
to proved reserves of the Property at December 31, 1996 is shown below and
should not be construed as the current market value. No deductions were made for
general overhead, depletion, depreciation and amortization, debt service, or any
indirect costs. Since the Property is not a separate tax-paying entity, the
standardized measure of discounted future net cash flows for the Property is
presented before deduction of income taxes.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Section 145 of the Delaware General Corporation Law ("Delaware Law")
permits, subject to certain conditions, a corporation to indemnify its
directors, officers, employees and agents against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such director, officer, employee or agent in connection with
threatened, pending or completed actions, suits and proceeding (other than
actions by or in the right of the corporation) in or to which any of such
persons is a party or is threatened to be made a party.

      Article 12 of the Company's Amended and Restated Certificate of
Incorporation and Article VI, Section 2 of the Company's Third Amended and
Restated Bylaws provide that Callon may indemnify its directors, officers,
employees and agents to the fullest extent permitted by Delaware Law.

      The Company currently maintains a policy insuring, subject to certain
exceptions, its directors and officers and the directors and officers of its
subsidiaries against liabilities that may be incurred by such persons acting in
such capacities.

      Pursuant to indemnification agreements, the Company has agreed to
indemnify its directors and certain officers against all costs, charges and
expenses incurred by reason of being a director or officer of the Company,
provided that indemnification is not prohibited in whole or in part under
applicable law.

registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

                            EXCHANGE AGENT AGREEMENT

                                 October 9, 1997

American Stock Transfer & Trust Company, New York
40 Wall Street
New York, New York

Ladies and Gentlemen:

      Callon Petroleum Company (the "Issuer") proposes to make an offer (the
"Exchange Offer") to exchange its outstanding 10.125% Series A Senior
Subordinated Notes due 2002 (the "Old Notes"), of which an aggregate of
$36,000,000 in principal amount is outstanding as of the date hereof, for an
equal principal amount of newly issued 10.125% Series B Senior Subordinated
Notes due 2002 (the "New Notes") which have been registered under the Securities
Act of 1933, as amended (the "Securities Act"). The Old Notes and New Notes are
collectively referred to herein as the "Notes." The terms and conditions of the
Exchange Offer as currently contemplated are set forth in a prospectus, dated
October 10, 1997 (the "Prospectus"), proposed to be distributed to all record
holders of the Old Notes and beneficial interests therein. Terms used and not
defined herein have the meanings set forth in the Prospectus or the Letter of
Transmittal (except that the term "Old Notes" shall include beneficial interests
therein, held by or through participants in The Depository Trust Company (the
"Book-Entry Transfer Facility") (Book-Entry Interests") and Old Notes held in
definitive registered form ("Definitive Registered Notes")).

      The Issuer hereby appoints American Stock Transfer & Trust Company, New
York to act as exchange agent (the "Exchange Agent") in connection with the
Exchange Offer. References hereinafter to "you" shall refer to American Stock
Transfer & Trust Company, New York.

      The Exchange Offer is expected to be commenced by the Issuer on or about
October 10, 1997. The Letter of Transmittal accompanying the Prospectus is to be
used by the holders of the Old Notes to accept the Exchange Offer, and contains
certain instructions with respect to the delivery of Book-Entry Interests and
Definitive Registered Notes.

      The Exchange Offer shall expire at 5:00 p.m., New York City time,
November 10, 1997 or on such later date or time to which the Issuer may extend
the Exchange Offer (the "Expiration Date"). Subject to the terms and conditions
set forth in the Prospectus, the Issuer expressly reserves the right to extend
the Exchange Offer from time to time and may extend the Exchange Offer by giving
oral (confirmed in writing) or written notice to you before 9:00 a.m., New York
City time, on the business day following the previously scheduled Expiration
Date.

      The Issuer expressly reserves the right to amend or terminate the Exchange
Offer, and not to accept for exchange any Old Notes not theretofore accepted for
exchange, upon the occurrence of any of the conditions of the Exchange Offer
specified in the Prospectus under the section "The Exchange Offer -- Conditions
to the Exchange Offer." The Issuer will give oral (confirmed in writing) or
written notice of any amendment, termination or nonacceptance to you as promptly
as practicable.

      In carrying out your duties as Exchange Agent, you are to act in
accordance with the following instructions:
<PAGE>
      1. You will perform such duties and only such duties as are specifically
set forth in the section of the Prospectus captioned "The Exchange Offer," as
specifically set forth in the Letter of Transmittal, and as specifically set
forth herein and such duties which are necessarily incidental thereto; PROVIDED,
HOWEVER, that in no way will your general duty to act in good faith be
discharged by the foregoing.

      2. You will establish an account with respect to the Old Notes at the
Book-Entry Transfer Facility for purposes of the Exchange Offer within two
business days after the date of the Prospectus or, if you already have
established an account with the Book-Entry Transfer Facility suitable for the
Exchange Offer, you will identify such preexisting account to be used in the
Exchange Offer, and any financial institution that is a participant in the
Book-Entry Transfer Facility's systems may make book-entry delivery of the Old
Notes by causing the Book-Entry Transfer Facility to transfer such Old Notes
into your account in accordance with the Book-Entry Transfer Facility's
procedure for such transfer.

      3. You are to examine each of the Letters of Transmittal, each of the
certificates for Old Notes in the case of Definitive Registered Notes, or, in
the case of Book-Entry Interests, confirmation of book-entry transfer into your
account at the Book-Entry Transfer Facility via the Book-Entry Transfer
Facility's Automated Tender Offer Program and any accompanying Agent's Message
and any other documents delivered or mailed to you by or for holders of the Old
Notes to ascertain whether: (i) the Letters of Transmittal and any such other
documents are duly executed and properly completed in accordance with
instructions set forth therein and (ii) the Old Notes have otherwise been
properly tendered. In each case where the Letter of Transmittal or any other
document has been improperly completed or executed, any of the certificates for
Old Notes are not in proper form for transfer or some other irregularity in
connection with the acceptance of the Exchange Offer exists, you will endeavor
to inform the presenters of the need for fulfillment of all requirements and to
take any other action as may be necessary or advisable to cause such
irregularity to be corrected.

      4. With the approval of the Chief Financial Officer of the Company or the
Company Secretary (such approval, if given orally, to be confirmed in writing)
or any other party designated by such an officer in writing, you are authorized
to waive any irregularities in connection with any tender of Old Notes pursuant
to the Exchange Offer.

      5. Tenders of Old Notes may be made only as set forth in the section of
the Prospectus captioned "The Exchange Offer -- Procedures for Tendering
Outstanding Notes" or in the Letter of Transmittal, and Old Notes shall be
considered properly tendered to you only when tendered in accordance with the
procedures set forth therein.

      Notwithstanding the provisions of this Paragraph 5, Old Notes which the
Chief Financial Officer of the Company or the Company Secretary or any other
party designated by such an officer in writing shall approve as having been
properly tendered shall be considered to be properly tendered (such approval, if
given orally, shall be confirmed in writing).

      6. You shall advise the Company with respect to any Old Notes delivered
subsequent to the Expiration Date and accept its instructions with respect to
disposition of such Old Notes.

      7. You shall accept tenders:

                  a. in cases  where the Old Notes  are  registered  in two or
            more names only if signed by all named holders;

                                       2
<PAGE>
                  b. in cases where the signing person (as indicated on the
            Letter of Transmittal) is acting in a fiduciary or a representative
            capacity only when proper evidence of his or her authority to so act
            is submitted; and

                  c. from persons other than the registered holder of Old Notes
            provided that customary transfer requirements, including any
            applicable transfer taxes, are fulfilled.

      8. Upon satisfaction or waiver of all of the conditions to the Exchange
Offer, the Issuer will notify you (such notice if given orally, to be confirmed
in writing) of its acceptance, promptly after the Expiration Date, of all Old
Notes properly tendered; and you, on behalf of the Issuer, will exchange such
Old Notes for New Notes and cause such Old Notes to be canceled. Delivery of New
Notes will be made on behalf of the Issuer by you at the rate of $1,000
principal amount of New Notes for each $1,000 principal amount of the Old Notes
tendered promptly after notice (such notice if given orally, to be confirmed in
writing) of acceptance of said Old Notes by the Issuer; PROVIDED, HOWEVER, that
in all cases, Old Notes tendered pursuant to the Exchange Offer will be
exchanged only after timely receipt by you of properly endorsed Definitive
Registered Notes or confirmation of book-entry transfer into your account at the
Book-Entry Transfer Facility, or a properly completed and duly executed Letter
of Transmittal (or facsimile thereof) with any required signature guarantees (or
in lieu thereof an Agent's Message, where applicable) and any other required
document. You shall issue New Notes only in denominations of $1,000 or any
integral multiple thereof.

      9. Tenders pursuant to the Exchange Offer are irrevocable, except that,
subject to the terms and upon the conditions set forth in the Prospectus and the
Letter of Transmittal, Old Notes tendered pursuant to the Exchange Offer may be
withdrawn at any time prior to the Expiration Date.

      10. The Issuer shall not be required to exchange any Old Notes tendered if
any of the conditions set forth in the Exchange Offer are not met. Notice of any
decision by the Issuer not to exchange any Old Notes tendered shall be given
(such notice, if given orally, shall be confirmed in writing) by the Issuer to
you.

      11. If, pursuant to the Exchange Offer, the Issuer does not accept for
exchange all or part of the Old Notes tendered because of an invalid tender, the
occurrence of certain other events set forth in the Prospectus under the caption
"The Exchange Offer -- Conditions to the Exchange Offers" or otherwise, you
shall as soon as practicable after the expiration or termination of the Exchange
Offer effect the appropriate book-entry transfer of the unaccepted Old Notes,
and return any related required documents and the Letters of Transmittal
relating thereto that are in your possession, to the persons who deposited them.

      12. You are not authorized to pay or offer to pay any concessions,
commission or solicitation fees to any broker, dealer, bank or other persons or
to engage or utilize any person to solicit tenders.

      13. As Exchange Agent hereunder you:

      a. will be regarded as making no representations and having no
responsibilities as to the validity, sufficiency, value or genuineness of Old
Notes, and will not be required to and will make no representations as to the
validity, value or genuineness of the Exchange Offer; PROVIDED, HOWEVER, that in
no way will your general duty to act in good faith be discharged by the
foregoing;

      b. shall not be obligated to take any legal action hereunder which might
in your reasonable judgment involve any expense or liability, unless you shall
have been furnished with reasonable indemnity;

                                       3
<PAGE>
      c. shall not be liable to the Issuer for any action taken or omitted by
you, or any action suffered by you to be taken or omitted, without negligence,
misconduct or bad faith on your part, by reason of or as a result of the
administration of your duties hereunder in accordance with the terms and
conditions of this Agreement or by reason of your compliance with the
instructions set forth herein or with any written or oral instructions delivered
to you pursuant hereto, and may reasonably rely on and shall be protected in
acting in good faith in reliance upon any certificate, instrument, opinion,
notice, letter, facsimile or other document or security delivered to you and
reasonably believed by you to be genuine and to have been signed by the proper
party or parties;

      d. may reasonably act upon any tender, statement, request, comment,
agreement or other instrument whatsoever not only as to its due execution and
validity and the effectiveness of its provisions, but also as to the truth and
accuracy of any information contained therein, which you shall in good faith
reasonably believe to be genuine or to have been signed or represented by a
proper person or persons;

      e. may rely on and shall be  protected  in acting  upon  written or oral
instructions  from any  officer of the  Issuer  with  respect to the  Exchange
Offer;

      f. shall not advise any person tendering Old Notes pursuant to the
Exchange Offer as to the wisdom of making such tender or as to the market value
or decline or appreciation in market value of any Old Notes; and

      g. may consult with your counsel and the written opinion of such counsel
shall be full and complete authorization and protection in respect of any action
taken, suffered or omitted by you hereunder in good faith and in accordance with
such written opinion of such counsel.

      14. You shall take such action as may from time to time be requested by
the Issuer or its counsel (and such other action as you may reasonably deem
appropriate) to furnish copies of the Prospectus, Letter of Transmittal and the
Notice of Guaranteed Delivery or such other forms as may be approved from time
to time by the Issuer to all persons requesting such documents and to accept and
comply with telephone requests for information relating to the Exchange Offer,
provided that such information shall relate only to the procedures for accepting
(or withdrawing from) the Exchange Offer. The Issuer will furnish you with
copies of such documents at your request. All other requests for information
relating to the Exchange Offer shall be directed to:

      Callon Petroleum Company
      200 North Canal Street
      Natchez, Mississippi  39120

and such other person or persons as the Company may request, daily, and more
frequently if reasonably requested, up to and including the Expiration Date, as
to the principal amount of the Old Notes which have been tendered pursuant to
the Exchange Offer and the items received by you pursuant to this Agreement,
separately reporting and giving cumulative totals as to items properly received
and items improperly received. In addition, you will also inform, and cooperate
in making available to, the Issuer or any such other person or persons as the
Issuer requests from time to time prior to the Expiration Date of such other
information as they, it or he reasonably requests. Such cooperation shall
include, without limitation, the granting by you to the Issuer and such persons
as the Issuer may request of access to those persons on your staff who are
responsible for receiving tenders in order to ensure that immediately prior to
the Expiration Date, the Issuer shall have received information in sufficient
detail to enable it to decide whether to extend the Exchange Offer. You shall
prepare a list of persons who failed to tender or whose tenders were not
accepted and the aggregate principal amount of Old Notes not tendered or Old
Notes not accepted and deliver said list to the Issuer at least seven days prior
to the Expiration Date. You shall also prepare a final list of all persons whose
tenders were accepted, the aggregate principal amount of Old Notes tendered and
the aggregate principal amount of Old Notes accepted and deliver said list to
the Issuer.

      16. Letters of Transmittal and Notices of Guaranteed Delivery shall be
stamped by you as to the date and the time of receipt thereof and shall be
preserved by you for a period of time at least equal to the period of time you
preserve other records pertaining to the transfer of securities. You shall
dispose of unused Letters of Transmittal and other surplus materials by
returning them to the Issuer.

      17. For services rendered as Exchange Agent hereunder you shall be
entitled to a fee not in excess of $500.

      18. You hereby acknowledge receipt of the Prospectus and the Letter of
Transmittal attached hereto and further acknowledge that you have examined each
of them to the extent that they relate to your duties hereunder. Any
inconsistency between this Agreement, on the one hand, and the Prospectus and
the Letter of Transmittal (as they may be amended from time to time), on the
other hand, shall be resolved in favor of the latter two documents, except with
respect to the duties, liabilities and indemnification of you as Exchange Agent
which shall be controlled by this Agreement.

      19. The Issuer agrees to indemnify and hold you harmless in your capacity
as Exchange Agent hereunder against any liability, cost or expense, including
reasonable attorneys' fees, arising out or in connection with the acceptance or
administration of your duties hereunder, including, without limitation, in
connection with any act, omission, delay or refusal made by you in reasonable
reliance upon any signature, endorsement, assignment, certificate, order,
request, notice, instruction or other instrument or document reasonably believed
by you to be valid, genuine and sufficient and in accepting any tender or
effecting any transfer of Old Notes reasonably believed by you in good faith to
be authorized, and in delaying or refusing in good faith to accept any tenders
or effect any transfer of Old Notes; PROVIDED, HOWEVER, that the Issuer shall
not be liable for indemnification or otherwise for any loss, liability, cost or
expense to the extent arising out of your negligence, willful breach of this
Agreement, willful misconduct or bad faith. In no case shall the Issuer be
liable under this indemnity with respect to any claim against you unless the
Issuer shall be notified by you, by letter or cable or by facsimile confirmed by
letter, of the written assertion of a claim against you or of any other action
commenced against you, promptly after you shall have received any such written
assertion or commencement of action. The Issuer shall be entitled to participate
at its own expense in the defense of any such claim or other action, and, if the
Issuer so elects, the Issuer shall assume the defense of any suit brought to
enforce any such claim. In the event that the Issuer shall assume the defense of
any such suit, the Issuer shall not be liable for the fees and expenses of any
additional counsel thereafter retained by you so long as the Issuer shall retain
counsel 

                                       5
<PAGE>
reasonably satisfactory to you to defend such suit. You shall not compromise or
settle any such action or claim without the consent of the Issuer.

      20. This Agreement and your appointment as Exchange Agent hereunder shall
be construed and enforced in accordance with the laws of the State of New York
applicable to agreements made and to be performed entirely within such state,
and without regard to conflicts of law principles, and shall inure to the
benefit of, and the obligations created hereby shall be binding upon, the
successors and assigns of each of the parties hereto.

      21. This Agreement may be executed in two or more counterparts, each of
which shall be deemed to be an original and all of which taken together
constitute one and the same agreement.

      22. In case any provision of this Agreement shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

      23. This Agreement shall not be deemed or construed to be modified,
amended, rescinded, canceled or waived, in whole or in part, except by a written
instrument signed by a duly authorized representative of the party to be
charged. This Agreement may not be modified orally.

      The undersigned acknowledges that he or she has received and reviewed the
Prospectus, dated October 10, 1997 (the "Prospectus"), of Callon Petroleum
Company, a Delaware corporation (the "Company"), and this Letter of Transmittal
(the "Letter"), which together constitute the Company's offer (the "Exchange
Offer") to exchange, from the registered holders (the "Holders") thereof an
aggregate principal amount of up to $36,000,000 of the Company's 10.125% Series
B Senior Subordinated Notes due 2002 (the "New Notes"), which have been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
pursuant to a Registration Statement of which the Prospectus is part, for a like
principal amount of the issued and outstanding 10.125% Series A Senior
Subordinated Notes due 2002 (the "Old Notes") of the Company.

      For each Old Note accepted for exchange, the Holder of such Old Note will
receive a New Note having a principal amount equal to that of the surrendered
Old Note. Accordingly, registered Holders of New Notes on the relevant record
date for the first interest payment date following the consummation of the
Exchange Offer will receive interest accruing from the most recent date to which
interest has been paid on the Old Notes or, if no interest has been paid, from
July 31, 1997. Old Notes accepted for exchange will cease to accrue interest
from and after the date of consummation of the Exchange Offer. Holders whose Old
Notes are accepted for exchange will not receive any payment in respect of
accrued interest on such Old Notes otherwise payable on 
<PAGE>
any interest payment date the record date for which occurs on or after
consummation of the Exchange Offer.

      This Letter is to be completed by a Holder of Old Notes either if
certificates for such Old Notes are to be forwarded herewith or if a tender is
to be made by book-entry transfer to the account maintained by the Exchange
Agent at The Depository Trust Company (the "Book-Entry Transfer Facility")
pursuant to the procedures set forth in "The Exchange Offer -- Procedures for
Tendering Outstanding Notes -- Book-Entry Transfer" section of the Prospectus
and an Agent's Message is not delivered. Tenders by book-entry transfer may also
be made by delivering an Agent's Message in lieu of this Letter of Transmittal.
The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to and received by the Exchange Agent and forming a part of a
Book-Entry Confirmation (as defined below), which states that the Book-Entry
Transfer Facility has received an express acknowledgment from the tendering
Participant, which acknowledgment states that such Participant has received and
agrees to be bound by the Letter of Transmittal and that the Company may enforce
the Letter of Transmittal against such Participant. Holders of Old Notes whose
certificates are not immediately available, or who are unable to deliver their
certificates or confirmation of the book-entry tender of their Old Notes into
the Exchange Agent's account at the Book-Entry Transfer Facility (a "Book-Entry
Confirmation") and all other documents required by this Letter to the Exchange
Agent on or prior to the Expiration Date, must tender their Old Notes according
to the guaranteed delivery procedures set forth in "The Exchange Offer --
Procedures for Tendering Outstanding Notes -- Guaranteed Delivery" section of
the Prospectus. See Instruction 1. Delivery of documents to the Book-Entry
Transfer Facility does not constitute delivery to the Exchange Agent.

      The undersigned has completed the appropriate boxes below and signed this
Letter to indicate the action the undersigned desires to take with respect to
the Exchange Offer.

      The undersigned, by completing the box entitled "Description of 10.125%
Series A Senior Subordinated Notes due 2002" below and signing this Letter, will
be deemed to have tendered the Old Notes as set forth in such box below.

Ladies and Gentlemen:

      Upon the terms and subject to the conditions of the Exchange Offer, the
undersigned hereby tenders to the Company the aggregate principal amount of Old
Notes indicated below. Subject to, and effective upon, the acceptance for
exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns
and transfers to, or upon the order of, the Company all right, title and
interest in and to such Old Notes as are being tendered hereby. The undersigned
hereby irrevocably constitutes and appoints the Exchange Agent its agent and
attorney-in-fact (with full knowledge that the Exchange Agent also acts as the
agent of the Company) with respect to the tendered Old Notes with full power of
substitution to (i) deliver certificates for such Old Notes, or transfer
ownership of such Old Notes on the account books maintained by DTC, to the
Company and deliver all accompanying evidences of transfer and authenticity to,
or upon the order of, the Company and (ii) present such Old Notes for transfer
on the books of the Company and receive all benefits and otherwise exercise all
rights of beneficial ownership of such Old Notes, all in accordance with the
terms of the Exchange Offer. The power of attorney granted in this paragraph
shall be deemed irrevocable and coupled with an interest.

      The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Old Notes
tendered hereby and that the Company will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claim when the same are accepted by the Company. The
undersigned hereby further represents that any New Notes acquired in exchange
for Old Notes tendered hereby will have been acquired in the ordinary course of
business of the person receiving such New Notes, whether or not such person is
the undersigned, that neither the Holder of such Old Notes nor any such other
person has an arrangement or understanding with any person to participate in the
distribution of such New Notes and that neither the Holder of such Old Notes nor
any such other person is an "affiliate," as defined in Rule 405 under the
Securities Act of 1933, as amended (the "Securities Act"), of the Company.

      The undersigned also acknowledges that the Exchange Offer are being made
in reliance on interpretations by the staff of the Securities and Exchange
Commission (the "SEC"), as set forth in no-action letters issued to third
parties, that the New Notes issued pursuant to the Exchange Offer in exchange
for the Old Notes may be offered for resale, resold and otherwise transferred by
Holders thereof (other than any such Holder which is an "affiliate" of the
Company within the meaning of Rule 405 under the Securities Act), without
compliance with the registration and prospectus delivery provisions of the
Securities Act, provided that such New Notes are acquired in the ordinary course
of such Holders' business and such Holders have no arrangement with any person
to participate in a distribution of such New Notes. However, the SEC has not
considered the Exchange Offer in the context of a no-action letter and there can
be no assurance that the staff of the SEC would make a similar determination
with respect to the Exchange Offer as in other circumstances. If the undersigned
is not a broker-dealer, the undersigned represents that it is not engaged in,
and does not intend to engage in, a distribution of New Notes and has no
arrangement or understanding to participate in a distribution of New Notes. If
any Holder is an affiliate of the Company, is engaged in or intends to engage
in, or has any arrangement or understanding with any person to participate in, a
distribution of the New Notes to be acquired pursuant to the Exchange Offer,
such Holder (i) could not rely on the applicable interpretations of the staff of
the SEC and (ii) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction. If
the undersigned is a broker-dealer that will receive New Notes for its own
account pursuant to the Exchange Offer, it represents that the Old Notes to be
exchanged for the New Notes were acquired by it as a result of market-making
activities or other trading activities and acknowledges that it will deliver a
prospectus in connection with any resale of such New Notes; however, by so
acknowledging and by delivering a prospectus, the undersigned will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.

                                      -5-
<PAGE>
      The undersigned will, upon request, execute and deliver any additional
documents deemed by the Company to be necessary or desirable to complete the
sale, assignment and transfer of the Old Notes tendered hereby. All authority
conferred or agreed to be conferred in this Letter and every obligation of the
undersigned hereunder shall be binding upon the successors, assigns, heirs,
executors, administrators, trustees in bankruptcy and legal representatives of
the undersigned and shall not be affected by, and shall survive, the death or
incapacity of the undersigned. This tender may be withdrawn only in accordance
with the procedures set forth in "The Exchange Offer --Withdrawal Rights"
section of the Prospectus. Unless otherwise indicated herein in the box entitled
"Special Issuance Instructions" below, please issue the New Notes (and, if
applicable, substitute certificates representing Old Notes for any Old Notes not
exchanged) in the name of the undersigned or, in the case of a book-entry
delivery of Old Notes, please credit the account indicated above maintained at
the Book-Entry Transfer Facility. Similarly, unless otherwise indicated under
the box entitled "Special Delivery Instructions" below, please send the New
Notes (and, if applicable, substitute certificates representing Old Notes for
any Old Notes not exchanged) to the undersigned at the address(es) shown above
in the box entitled "Description of 10.125% Series A Senior Subordinated Notes
due 2002."

        FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

      1. DELIVERY OF THIS LETTER AND OLD NOTES, GUARANTEED DELIVERY PROCEDURES.
This Letter is to be completed by holders of Old Notes either if certificates
for such Old Notes are to be forwarded herewith or if tenders are to be made
pursuant to the procedures for delivery by book-entry transfer set forth in "The
Exchange Offer -- Procedures for Tendering Outstanding Notes -- Book Entry
Transfer" section of the Prospectus and an Agent's Message is not delivered.
Tenders by book-entry transfer may also be made by delivering an Agent's Message
in lieu of this Letter of Transmittal. The term "Agent's Message" means a
message, transmitted by the Book-Entry Transfer Facility to and received by the
Exchange Agent and forming a part of a Book-Entry Confirmation, which states
that the Book-Entry Transfer Facility has received an express acknowledgment
from the tendering Participant, which acknowledgment states that such
Participant has received and agrees to be bound by the Letter of Transmittal and
that the Company may enforce the Letter of Transmittal against such Participant.
Certificates for all physically tendered Old Notes, or Book-Entry Confirmation,
as the case may be, as well as a properly completed and duly executed Letter (or
facsimile hereof or Agent's Message in lieu thereof) and any other documents
required by this Letter, must be received by the Exchange Agent at the address
set forth herein on or prior to the Expiration Date, or the tendering holder
must comply with the guaranteed delivery procedures set forth below. Old Notes
tendered hereby must be in denominations of principal amount of $1,000 and any
integral multiple thereof.

      Holders whose certificates for Old Notes are not immediately available or
who cannot deliver their certificates and all other required documents to the
Exchange Agent on or prior to the Expiration Date, or who cannot complete the
procedure for book-entry transfer on a timely basis, may tender their Old Notes
pursuant to the guaranteed delivery procedures set forth in "The Exchange Offer
- -- Procedures for Tendering Outstanding Notes -- Guaranteed Delivery" section of
the Prospectus. Pursuant to such procedures, (i) such tender must be made
through an Eligible Institution; (ii) on or prior to 5:00 p.m., New York City
time, on the Expiration Date, the Exchange Agent must receive from such Eligible
Institution a properly completed and duly Notice of Guaranteed Delivery,
substantially in the form provided by the Company (by telegram, telex, facsimile
transmission, mail or hand delivery), setting forth the name and address of the
holder of Old Notes and the amount of Old Notes tendered stating that the tender
is being made thereby and guaranteeing that within five New York Stock Exchange
("NYSE") trading days after the date of execution of the Notice of Guaranteed
Delivery, the certificates for all physically tendered Old Notes, in proper form
for transfer, or a Book-Entry Confirmation, as the case may be, together with a
properly completed and duly executed Letter (or facsimile thereof or Agent's
Message in lieu thereof) with any required signature guarantees and any other
documents required by this Letter will be deposited by the Eligible Institution
with the Exchange Agent; and (iii) the certificates for all physically tendered
Old Notes, in proper form for transfer, or Book-Entry Confirmation, as the case
may be, together with a properly completed and duly executed Letter (or
facsimile thereof or Agent's Message in lieu thereof) with any required
signature guarantees and all other documents required by this Letter, are
deposited by the Eligible Institution within five NYSE trading days after the
date of execution of the Notice of Guaranteed Delivery.

      The method of delivery of this Letter, the Old Notes and all other
required documents is at the election and risk of the tendering Holders, but the
delivery will be deemed made only when actually received or confirmed by the
Exchange Agent. If Old Notes are sent by mail, it is suggested that the mailing
be registered mail, properly insured, with return receipt requested, and made
sufficiently in advance of the Expiration Date to permit delivery to the
Exchange Agent prior to 5:00 p.m., New York City time, on the Expiration Date.

                                      -8-
<PAGE>
      Only a Holder (as defined in the Prospectus) of Old Notes may tender such
Old Notes in the Exchange Offer. Any beneficial holder of Old Notes who is not
the registered holder and who wishes to tender should arrange with the
registered holder to execute and deliver this Letter of Transmittal on his
behalf or must, prior to completing and executing this Letter of Transmittal and
delivering his Old Notes, either make appropriate arrangements to register
ownership of the Old Notes in such holder's name or obtain a properly completed
bond power from the registered holder.

      All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Old Notes and withdrawal of tendered Old Notes
will be determined by the Company in its sole discretion, which determination
will be final and binding. The Company reserves the absolute right to reject any
and all Old Notes not properly tendered or any Old Notes the Company's
acceptance of which would, in the opinion of counsel for the Company, be
unlawful. The Company also reserves the right to waive any irregularities or
conditions of tender as to particular Old Notes. The Company's interpretation of
the terms and conditions of the Exchange Offer (including the instructions in
this Letter of Transmittal) shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of Old Notes
must be cured within such time as the Company shall determine. Neither the
Company, the Exchange Agent nor any other person shall be under any duty to give
notification of defects or irregularities with respect to tenders of Old Notes,
nor shall any of them incur any liability for failure to give such notification.
Tenders of Old Notes will not be deemed to have been made until such defects or
irregularities have been cured or waived. Any Old Notes received by the Exchange
Agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering Holders of Old Notes, unless otherwise provided in this
Letter of Transmittal, as soon as practicable following the Expiration Date. See
"The Exchange Offer" section of the Prospectus.

      2. PARTIAL TENDERS (NOT APPLICABLE TO NOTE HOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER). If less than all of the Old Notes evidenced by a submitted
certificate are to be tendered, the tendering Holder(s) should fill in the
aggregate principal amount of Old Notes to be tendered in the box above entitled
"Description of 10.125% Series A Senior Subordinated Notes due 2002 -- Principal
Amount Tendered." A reissued certificate representing the balance of nontendered
Old Notes will be sent to such tendering holder, unless otherwise provided in
the appropriate box of this Letter, promptly after the Expiration Date. All of
the Old Notes delivered to the Exchange Agent will be deemed to have been
tendered unless otherwise indicated.

      3. SIGNATURES ON THIS LETTER, BOND POWERS AND ENDORSEMENTS, GUARANTEE OF
SIGNATURES. If this Letter is signed by the Holder of the Old Notes tendered
hereby, the signature must correspond exactly with the name as written on the
face of the certificates or on a DTC security position listing without any
change whatsoever.

      If any tendered Old Notes are owned of record by two or more joint owners,
all of such owners must sign this Letter.

      If any tendered Old Notes are registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
copies of this letter as there are different registrations of certificates.

      When this Letter is signed by the registered holder or holders of the Old
Notes specified herein and tendered hereby, no endorsements of certificates or
separate bond powers are required. If, however, the New Notes are to be issued,
or any untendered Old Notes are to be reissued, to a person other than the
registered holder, then endorsements of any certificates transmitted hereby or
separate bond powers are required. Signatures on such certificate(s) must be
guaranteed by an Eligible Institution.

                                       -9-

      If this Letter is signed by a person other than the registered holder or
holders of any certificate(s) specified herein, such certificate(s) must be
endorsed accompanied by appropriate bond powers, in either case signed exactly
as the name or names of the registered holder or holders appear(s) on the
certificate(s) and signatures on such certificate(s) must be guaranteed by an
Eligible Institution.

      If this Letter or any certificates or bond powers are signed by trustees,
executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and, unless waived by the Company,
proper evidence satisfactory to the Company of their authority to so act must be
submitted.

      Endorsements on certificates for Old Notes or signatures on bond powers
required by this Instruction 3 must be guaranteed by a financial institution
(including most banks, savings and loan associations and brokerage houses) that
is a participant in the [Securities Transfer Agents Medallion Program, the New
York Stock Exchange Medallion Signature Program or the Stock Exchanges Medallion
Program] (each, an "Eligible Institution").

      Signatures on this Letter need not be guaranteed by an Eligible
Institution, provided the Old Notes are tendered: (i) by a registered holder of
Old Notes who has not completed the box entitled "Special Issuance Instructions"
or "Special Delivery Instructions" on this Letter, or (ii) for the account of an
Eligible Institution.

      4. SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering holders of Old
Notes should indicate in the applicable box the name and address to which New
Notes issued pursuant to the Exchange Offer and/or substitute certificates
evidencing Old Notes not exchanged are to be issued or sent, if different from
the name or address of the person signing this Letter. In the case of issuance
in a different name, the employer identification or social security number of
the person named must also be indicated. Note holders tendering Old Notes by
book-entry transfer may request that Old Notes not exchanged be credited to such
account maintained at the Book-Entry Transfer Facility as such noteholder may
designate hereon. If no such instructions are given, such Old Notes not
exchanged will be returned to the name and address of the person signing this
Letter.

      5. TRANSFER TAXES. The Company will pay all transfer taxes, if any,
applicable to the transfer of Old Notes to it or its order pursuant to the
Exchange Offer. If, however, New Notes and/or substitute Old Notes not exchanged
are to be delivered to, or are to be registered or issued in the name of, any
person other than the registered holder of the Old Notes tendered hereby, or if
tendered Old Notes are registered in the name of any person other than the
person signing this Letter, or if a transfer tax is imposed for any reason other
than the transfer of Old Notes to the Company or its order pursuant to the
Exchange Offer, the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted herewith, the amount of such transfer taxes will be billed to such
tendering holder and the Exchange Agent will retain possession of an amount of
New Notes with a face amount equal to the amount of such transfer taxes due by
such tendering holder pending receipt by the Exchange Agent of the amount of
such taxes.

      Except as provided in this Instruction 5, it will not be necessary for
transfer tax stamps to be affixed to the Old Notes specified in this Letter.

      6. WAIVER OF CONDITIONS. The Company reserves the absolute right to waive
satisfaction of any or all conditions enumerated in the Prospectus.

                                      -10-
<PAGE>
      7. NO CONDITIONAL TENDERS. No alternative, conditional, irregular or
contingent tenders will be accepted. All tendering holders of Old Notes, by
execution of this Letter or on Agent's Message in lieu thereof, shall waive any
right to receive notice of the acceptance of their Old Notes for exchange.

      Although the Company intends to notify holders of defects or
irregularities with respect to tenders of Old Notes, neither the Company, the
Exchange Agent nor any other person shall incur any liability for failure to
give any such notice.

      8. MUTILATED, LOST, STOLEN OR DESTROYED OLD NOTES. Any holder whose Old
Notes have been mutilated, lost, stolen or destroyed should contact the Exchange
Agent at the address indicated above for further instructions.

      9. WITHDRAWAL OF TENDERS. Tenders of Old Notes may be withdrawn at any
time prior to 5:00 p.m., New York City time, on the Expiration Date. For a
withdrawal of a tender of Old Notes to be effective, a written, telegraphic,
telex or facsimile transmission notice of withdrawal must be received by the
Exchange Agent at its address set forth above prior to 5:00 p.m., New York City
time, on the Expiration Date. Any such notice of withdrawal must (i) specify the
name of the person having deposited the Old Notes to be withdrawn (the
"Depositor"), (ii) identify the Old Notes to be withdrawn (including the
certificate number or numbers (where certificates for Old Notes have been
transmitted) and principal amount of such Old Notes), (iii) be signed by the
holder in the same manner as the original signature on this Letter (including
any required signature guarantees) or be accompanied by documents of transfer
sufficient to have the trustee under the Indenture register the transfer of such
Old Notes into the name of the person withdrawing the tender and (iv) specify
the name in which any such Old Notes are registered, if different from that of
the Depositor. All questions as to the validity, form and eligibility (including
time of receipt) of such notices will be determined by the Company, whose
determination shall be final and binding on all parties. Any Old Notes so
withdrawn will be deemed not to have been validly tendered for exchange for
purposes of the Exchange Offer. Any Old Notes that have been tendered for
exchange but which are not exchanged for any reason will be returned to the
holder thereof without cost to such holder as soon as practicable after
withdrawal, rejection of tender or termination of the Exchange Offer. Properly
withdrawn Old Notes may be retendered by following the procedures described
above at any time on or prior to 5:00 p.m., New York City time, on the
Expiration Date.

      10. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to
the procedure for tendering, as well as requests for additional copies of the
Prospectus, this Letter and other related documents may be directed to the
Exchange Agent, at the address and telephone number indicated above.

      11. IMPORTANT TAX INFORMATION. Under current federal income tax law, a
holder of New Notes is required to provide the Company (as payor) with such
holder's correct taxpayer identification number ("TIN") on Substitute Form W-9
or otherwise establish a basis for exemption from backup withholding to prevent
backup withholding on any New Notes delivered pursuant to the Exchange Offer and
any payments received in respect of the New Notes. If a holder of New Notes is
an individual, the TIN is such holder's social security number. If the Company
is not provided with the correct taxpayer identification number, a holder of New
Notes may be subject to a $50 penalty imposed by the Internal Revenue Service.
Accordingly, each prospective holder of New Notes to be issued pursuant to
Special Issuance Instructions should complete the attached Substitute Form W-9.
The Substitute Form W-9 need not be completed if the box entitled Special
Issuance Instructions has not been completed.

                                      -11-
<PAGE>
      Certain holders of New Notes (including, among others, all corporations
and certain foreign individuals) are not subject to these backup withholding and
reporting requirements. Exempt prospective holders of New Notes should indicate
their exempt status on Substitute Form W-9. A foreign individual may qualify as
an exempt recipient by submitting to the Company, through the Exchange Agent, a
properly completed Internal Revenue Service Form W-8 (which the Exchange Agent
will provide upon request) signed under penalty of perjury, attesting to the
holder's exempt status. See the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional
instructions.

      If backup withholding applies, the Company is required to withhold 31% of
any payment made to the holder of New Notes or other payee. Backup withholding
is not an additional federal income tax. Rather, the federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of tax withheld. If withholding results in an overpayment of taxes, a refund may
be obtained from the Internal Revenue Service. To prevent backup withholding on
any New Notes delivered pursuant to the Exchange Offer and any payments received
in respect of the New Notes, each prospective holder of New Notes to be issued
pursuant to Special Issuance Instructions should provide the Company, through
the Exchange Agent, with either: (i) such prospective holder's correct TIN by
completing the form below, certifying that the TIN provided on Substitute Form
W-9 is correct (or that such prospective holder is awaiting a TIN) and that (A)
such prospective holder has not been notified by the Internal Revenue Service
that he or she is subject to backup withholding as a result of a failure to
report all interest or dividends or (B) the Internal Revenue Service has
notified such prospective holder that he or she is no longer subject to backup
withholding; or (ii) an adequate basis for exemption.

      The prospective holder of New Notes to be issued pursuant to Special
Issuance Instructions is required to give the Exchange Agent the TIN (e.g.,
social security number or employer identification number) of the prospective
record owner of the New Notes. If the New Notes will be held in more than one
name or are not held in the name of the actual owner, consult the enclosed
Guidelines for Certification of Taxpayer Identification Number on Substitute
Form W-9 for additional guidance regarding which number to report.

      To prevent backup withholding, each tendering holder of Old Notes must
provide its correct TIN by completing the Substitute Form W-9 set forth below,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN) and that (i) the holder is exempt from backup withholding, or (ii) the
holder has not been notified by the Internal Revenue Service that such holder is
subject to backup withholding as a result of a failure to report all interest or
dividends or (iii) the Internal Revenue Service has notified the holder that
such holder is no longer subject to backup withholding. If the tendering holder
of Old Notes is a nonresident alien or foreign entity not subject to backup
withholding, such holder must give the Company a completed Form W-8, Certificate
of Foreign Status. These forms may be obtained from the Exchange Agent. If the
Old Notes are in more than one name or are not in the name of the actual owner,
such holder should consult the W-9 Guidelines for information on which TIN to
report. If such holder does not have a TIN, such holder should consult the W-9
Guidelines for instructions on applying for a TIN, check the box in Part 2 of
the Substitute Form W-9 and write "applied for" in lieu of its TIN. Note:
Checking this box and writing "applied for" on the form means that such holder
has already applied for a TIN or that such holder intends to apply for one in
the near future. If such holder does not provide its TIN to the Company within
60 days, backup withholding will begin and continue until such holder furnishes
its TIN to the Company.
