  THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M, NEW YORK CITY TIME ON JULY 12,
1996 UNLESS EXTENDED.
 
  Coda Energy, Inc., a Delaware corporation ("Coda;" and, together with the
guarantor subsidiaries, Diamond Energy Operating Company, Taurus Energy Corp.
and Electra Resources, Inc., the "Company"), is hereby offering (the "Exchange
Offer"), upon the terms and subject to the conditions set forth in this
Prospectus and the accompanying Letter of Transmittal (the "Letter of
Transmittal"), to exchange $1,000 principal amount of its 10 1/2% Series B
Senior Subordinated Notes due 2006 (the "Exchange Notes"), which exchange has
been registered under the Securities Act of 1933, as amended (the "Securities
Act"), pursuant to a registration statement of which this Prospectus is a part
(the "Registration Statement"), for each $1,000 principal amount of its
outstanding 10 1/2% Series A Senior Subordinated Notes due 2006 (the "Private
Notes"), of which $110,000,000 in aggregate principal amount was issued on
March 18, 1996 and is outstanding as of the date hereof. The form and terms of
the Exchange Notes are the same as the form and terms of the Private Notes
(which they replace) except that (i) the Exchange Notes will bear a Series B
designation, (ii) the Exchange Notes will have been registered under the
Securities Act, and, therefore, the Exchange Notes will not bear legends
restricting the transfer thereof and (iii) holders of the Exchange Notes will
not be entitled to certain rights of holders of the Private Notes under the
Registration Rights Agreement (as defined herein), which rights will terminate
upon the consummation of the Exchange Offer. The Exchange Notes will evidence
the same indebtedness as the Private Notes (which they replace) and will be
entitled to the benefits of an indenture dated as of March 18, 1996 governing
the Private Notes and the Exchange Notes (the "Indenture"). The Private Notes
and the Exchange Notes are referred to herein collectively as the "Notes." See
"The Exchange Offer" and "Description of Exchange Notes."
 
  The Exchange Notes will bear interest at the same rate and on the same terms
as the Private Notes. Consequently, the Exchange Notes will bear interest at
the rate of 10 1/2% per annum and the interest thereon will be payable
semiannually in arrears on April 1 and October 1 of each year, commencing
October 1, 1996. The Exchange Notes will bear interest from and including the
date of issuance of the Private Notes (March 18, 1996). Holders whose Private
Notes are accepted for exchange will be deemed to have waived the right to
receive any interest accrued on the Private Notes.
 
  The Exchange Notes will be general unsecured obligations of Coda and will be
subordinated in right of payment to all Senior Debt (as defined in the
Indenture) of Coda (which includes all indebtedness under the Credit Agreement
(as defined herein)) and will rank senior in right of payment to all future
subordinated indebtedness of Coda. As of March 31, 1996, Coda had $81.8
million in Senior Debt. Coda currently has no indebtedness that is junior to
the Notes. See "Description of Exchange Notes--Subordination" and "Description
of Other Indebtedness."
 
  Coda's payment obligations under the Exchange Notes will be jointly and
severally guaranteed on a senior subordinated basis (the "Subsidiary
Guarantees") by all of Coda's current and future Restricted Subsidiaries (as
defined in the Indenture; collectively, the "Guarantors"). The Subsidiary
Guarantees will be subordinated to the guarantees of Senior Debt issued by the
Guarantors under the Credit Agreement and to other guarantees of Senior Debt
issued in the future. See "Description of Exchange Notes--Subsidiary
Guarantees."
 
  The Exchange Notes will be redeemable at the option of Coda, in whole or in
part, at any time on or after April 1, 2001, at the redemption prices set
forth herein, together with accrued and unpaid interest thereon to the date of
redemption. Notwithstanding the foregoing, before March 12, 1999, Coda may, on
any one or more occasions, redeem up to $27.5 million in aggregate principal
amount of Notes at a redemption price of 110.5% of the principal amount
thereof plus accrued and unpaid interest thereon to the redemption date, with
the net proceeds of an offering of common equity of Coda; provided that at
least $82.5 million in aggregate principal amount of Notes must remain
outstanding immediately after the occurrence of such redemption; and provided,
further, that any such redemption shall occur within 75 days of the date of
the closing of such offering of common equity of Coda. See "Description of
Exchange Notes."
 
  Upon the occurrence of a Change of Control (as defined herein), each holder
of Exchange Notes may require Coda to repurchase all or a portion of such
holder's Exchange Notes at a repurchase price equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest thereon to the date
of repurchase. See "Description of Exchange Notes--Repurchase of the Option of
Holders--Change of Control."
 
  The Company will accept for exchange any and all validly tendered Private
Notes not withdrawn prior to 5:00 p.m., New York City time, on July 12, 1996,
unless the Exchange Offer is extended by the Company in its sole discretion
(the "Expiration Date"). Tenders of Private Notes may be withdrawn at any time
prior to the Expiration Date. Private Notes may be tendered only in integral
multiples of $1,000. The Exchange Offer is subject to certain customary
conditions. See "The Exchange Offer--Conditions."

  Based on an interpretation by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that the Exchange Notes issued pursuant to the
Exchange Offer in exchange for Private Notes may be offered for resale, resold
and otherwise transferred by a holder thereof (other than (i) a broker-dealer
who purchases such Exchange Notes directly from the Company to resell pursuant
to Rule 144A or any other available exemption under the Securities Act or (ii)
a person that 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 the holder
is acquiring the Exchange Notes in the ordinary course of its business and is
not participating, and had no arrangement or understanding with any person to
participate, in the distribution of the Exchange Notes. Holders of Private
Notes wishing to accept the Exchange Offer must represent to the Company, as
required by the Registration Rights Agreement, that such conditions have been
met. Each broker-dealer that receives Exchange Notes for its own account in
exchange for Private Notes, where such Private 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. The Company believes that none of the
registered holders of the Private Notes is an affiliate (as such term is
defined in Rule 405 under the Securities Act) of the Company.
 
  Prior to the Exchange Offer, there has been no public market for the Private
Notes. The Company does not intend to list the Exchange Notes on any securities
exchange or to seek approval for quotation through any automated quotation
system. There can be no assurance that an active market for the Exchange Notes
will develop. To the extent that a market for the Notes does develop, the
market value of the Notes will depend on market conditions (such as yields on
alternative investments), general economic conditions, the Company's financial
condition and certain other factors. Such conditions might cause the Notes, to
the extent that they are traded, to trade at a significant discount from face
value. See "Risk Factors--Absence of Public Market for the 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 Private Notes where such Private Notes
were acquired by such broker-dealer as a result of market-making activities or
other trading activities. The Company has agreed to make this Prospectus (as it
may be amended or supplemented) available to any broker-dealer for use in
connection with any such resale for a period of one year after the effective
date of the Registration Statement of which this Prospectus forms a part. See
"Plan of Distribution."
 
  The Company will not receive any proceeds from, and has agreed to bear the
expenses of, the Exchange Offer. No underwriter is being used in connection
with this Exchange Offer. See "The Exchange Offer--Resale of the Exchange
Notes."
 
  THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT
SURRENDERS FOR EXCHANGE FROM, HOLDERS OF PRIVATE 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.
 
  NO PERSON IS AUTHORIZED IN CONNECTION WITH THE EXCHANGE OFFER TO GIVE ANY
INFORMATION OR TO MAKE ANY REPRESENTATION NOT CONTAINED IN THIS PROSPECTUS OR
THE ACCOMPANYING LETTER OF TRANSMITTAL, AND, IF GIVEN OR MADE, SUCH INFORMATION
OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED BY THE
COMPANY. NEITHER THE DELIVERY OF THIS PROSPECTUS OR THE ACCOMPANYING LETTER OF
TRANSMITTAL, NOR ANY EXCHANGE MADE HEREUNDER SHALL UNDER ANY CIRCUMSTANCES
CREATE ANY IMPLICATION THAT THE INFORMATION CONTAINED HEREIN IS CORRECT AS OF
ANY DATE SUBSEQUENT TO THE DATE HEREOF.

IN CONNECTION THEREWITH. THIS IS IN ADDITION TO THE OBLIGATION OF DEALERS TO
DELIVER A PROSPECTUS WHEN ACTING AS UNDERWRITERS AND WITH RESPECT TO THEIR
UNSOLD ALLOTMENTS OR SUBSCRIPTIONS.
 
  The Exchange Notes will be available initially only in book-entry form. The
Company expects that the Exchange Notes issued pursuant to the Exchange Offer
will be issued in the form of one permanent global certificate in definitive,
fully-registered form ("Global Note") that will be deposited with, or on
behalf of, the Depository Trust Company ("DTC" or the "Depositary") and
registered in its name or in the name of Cede & Co., as its nominee.
Beneficial interests in the Global Note representing the Exchange Notes will
be shown on, and transfers thereof will be effected only through, records
maintained by the Depositary and its participants. After the initial issuance
of such Global Note, Exchange Notes in certificated form will be issued in
exchange for the Global Note only in accordance with the terms and conditions
set forth in the Indenture. See "The Exchange Offer--Book-Entry Transfer" and

                                    SUMMARY
 
  The following summary is qualified in its entirety by the detailed
information, financial statements and other data appearing elsewhere in this
Prospectus. The pro forma financial data presented give effect as of January 1,
1995, to (i) the Snyder Acquisition (as defined below), (ii) the Merger (as
defined below) and (iii) the offering of the Private Notes and the application
of the estimated net proceeds therefrom. Certain oil and gas terms used in this
Prospectus are defined in the "Glossary" included herein. Certain terms used in
connection with the Notes are defined under the caption "Description of
Exchange Notes--Certain Definitions."
 
                                  THE COMPANY
 
  The Company is an independent energy company that is principally engaged in
the acquisition and exploitation of producing oil and natural gas properties.
The Company also owns and operates natural gas processing and liquids
extraction facilities and natural gas gathering systems. The Company seeks to
acquire oil and natural gas properties whose predominant economic value is
attributable to proved producing reserves and to enhance that value through
control of operations, reduction of costs and property development. The
Company's producing properties are concentrated in the mid-continent region of
the United States. At December 31, 1995, the Company had proved reserves of
42.6 Mmbbls of oil and 37.1 Bcf of natural gas, aggregating 48.8 Mmboe. Company
operated properties accounted for approximately 94% of its 1995 production of
3.9 Mmboe.
 
  As a result of the Company's successful acquisition and exploitation
activities, the Company has shown significant growth in reserves, production
and earnings before interest, income taxes, depletion, depreciation and
amortization ("EBITDA") over the last five years. From 1991 through 1995, the
Company achieved an average annual reserve replacement of 480% at an average
cost of $3.67 per Boe. To achieve these results, management estimates that the
Company evaluated, over the last five years, in excess of 1,400 acquisition
opportunities with an aggregate market value estimated by management to exceed
$15 billion. Over the same period, management estimates that the Company made
approximately 280 offers totaling more than $3 billion and successfully closed
in excess of 50 transactions having an aggregate purchase price of $172.2
million. This strategy enabled the Company to increase average net daily
production from 3,329 Boe in 1991 to 10,688 Boe in 1995, representing a
compound annual growth rate of 34%. Similarly, EBITDA increased at a 46%
compound annual growth rate from $8.2 million in 1991 to $37.3 million in 1995.

Properties."

                                    STRATEGY
 
  The Company's strategy is to increase oil and natural gas reserves,
production and cash flow by selectively acquiring and exploiting oil and
natural gas properties, especially those properties with enhanced recovery and
other lower risk development potential. In order to implement its strategy, the
Company principally seeks to acquire oil and natural gas properties with the
following characteristics:
 
  .  Geographic Focus--The Company has focused its acquisition activities in
     the mid-continent region of the United States. This region includes oil
     and natural gas basins with geological and production characteristics
     potentially responsive to the Company's exploitation and development
     techniques. Management believes that it has considerable experience in,
     and knowledge of, this region. The Company presently has four core
     operating areas: west Texas, north Texas, west central Oklahoma and
     southwestern Kansas. The geographic proximity of the Company's various
     properties allows the Company to minimize the number of operations and
     field production offices that it must maintain and the number of
     supervisory personnel that it must employ.
 
  .  Proved Developed Reserves--The Company prefers to acquire properties
     where the majority of the reserves are proved developed reserves
     producing from relatively shallow horizons. Management believes these
     properties generally present lower geologic and mechanical risks for
     drilling, recompleting and operating activities. Substantially all of
     the Company's wells are under 10,000 feet deep.
 
  .  Operated, High Working Interest Properties--The Company prefers to
     operate the properties it acquires and to own the majority working
     interest in those properties. This allows the Company greater control
     over (i) timing and plans for future development, (ii) drilling,
     completing and lifting costs and (iii) marketing of production. At
     December 31, 1995, the Company operated 2,052 of the 2,190 gross
     producing and active water injection wells in which it owned an
     interest, and its weighted average working interest in its properties
     was approximately 82%.
 
  .  Exploitation Potential--The Company seeks to increase production and
     recoverable reserves through exploitation efforts on the properties it
     acquires. Exploitation efforts include workovers and/or recompletions of
     existing wells; the initiation of, or improvements to, secondary
     recovery projects, particularly the use of waterflooding; and the
     drilling of lower risk development and/or infill wells. The Company
     believes that it has been able to enhance the value and to extend the
     economic life of many of the properties that it has acquired by
     utilizing techniques such as these.
 
  .  Cost Reduction Potential--The Company seeks to acquire properties where
     significant economic value can be created by lowering operating costs.
     The Company believes that it has been able to lower the lifting costs on
     certain properties it has acquired in comparison to the costs incurred
     by the major oil companies and larger independents that previously
     operated the properties. These savings were achieved through reductions
     in labor, electricity, materials and other costs.
 
  .  Price Improvement Potential--Whenever possible, the Company attempts to
     negotiate more favorable marketing agreements than those in place under
     prior owners. After the Company has begun its exploitation activities on
     its properties, it may attempt to negotiate more favorable prices as the
     volumes of oil increase. Certain of the Company's oil purchasers have
     paid and are currently paying a premium over posted prices and have
     eliminated certain quality and marketing deductions for a portion of the
     Company's oil production due to the Company's control over a significant
     volume of oil production in its core geographic areas.
 
                                       5
<PAGE>
 
 
  The Company believes that future acquisitions, like its past acquisitions,
will come from several categories of sellers including: (i) major oil
companies; (ii) companies that are consolidating operations to achieve cost
savings; (iii) companies and individuals owning interests in wells in which the
Company owns a substantial working interest; and (iv) companies with limited
capital resources.
 
  The success of the Company's strategy depends upon a number of factors
outside of the Company's control, including the availability of attractive
acquisition opportunities. In recent years, major oil companies have been
divesting many of their higher cost domestic oil and natural gas properties. In
addition, the oil and natural gas industry continues to consolidate as smaller
independents exit the business. The Company believes these trends will
continue. By increasing production and lowering operating costs, the Company
believes that it can increase economic value and cash flow as well as extend
the productive lives of these properties. However, there can be no assurance
that the Company will be able to successfully implement its operating strategy.
See "Risk Factors--Acquisition Risks; Depletion of Reserves" and "Business--
Exploitation and Development Activities."
 
                    RECENT ACQUISITION OF CERTAIN PROPERTIES
 
  On October 6, 1995, the Company acquired 63 producing oil and natural gas
properties and related assets (the "Snyder Acquisition") from Snyder Oil
Corporation ("Snyder"). The majority of these properties are located in the
Permian Basin in west Texas. The total purchase price of these properties was
$17.1 million in cash, of which $16.0 million was financed with borrowings
under the Company's then-existing credit agreement. Total proved reserves of
these properties were estimated as of October 1, 1995, to be 4.3 Mmbbls of oil
and 6.8 Bcf of natural gas. The Company believes that these properties present
exploitation opportunities, including opportunities to implement cost-cutting
strategies and initiate or improve secondary recovery operations and lower risk
development drilling activities. Additionally, the Snyder Acquisition
complements the Company's core operating areas within the mid-continent region
of the United States. See Pro Forma Condensed Financial Statements.
 
                                     TAURUS
 
  Through its Taurus Energy Corp. ("Taurus") subsidiary, the Company also owns
and operates three gas processing and liquid extraction facilities and
approximately 700 miles of gas gathering systems, primarily located in west
central Texas. Taurus was acquired by the Company in April 1994. The Company's
gas gathering and processing revenues, from Taurus and its predecessor, have
grown from $5.2 million in 1991 to $35.6 million in 1995, and EBITDA has
increased from $50,000 to $3.4 million over the same period. Taurus represented
approximately nine percent of the Company's consolidated 1995 EBITDA of
approximately $37.3 million. The Company intends to study alternatives for
maximizing the value of its investment in Taurus. These alternatives could
include a sale of Taurus, whether by merger, sale of all or substantially all
of the assets of Taurus or sale of all of the capital stock of Taurus.

                                   THE MERGER
 
  On February 16, 1996, pursuant to an Agreement and Plan of Merger dated as of
October 30, 1995 (as amended, the "Merger Agreement"), by and among Coda, Joint
Energy Development Investments Limited Partnership ("JEDI"), which is an
affiliate of Enron Capital & Trade Resources Corp. ("ECT"), and Coda
Acquisition, Inc. ("CAI"), which was a subsidiary of JEDI, JEDI acquired Coda
through a merger (the "Merger") at a price of $7.75 per share in cash (for an
aggregate purchase price of approximately $176.2 million). Concurrently with
the execution of the Merger Agreement, JEDI and CAI entered into certain
agreements with members of the Company's management (the "Management Group").
Following consummation of the Merger, the Management Group owns approximately
5% of Coda's common stock on a fully-diluted basis. JEDI owns the remaining
95%. JEDI was formed as a limited partnership between California Public
Employees' Retirement System ("CalPERS") and an affiliate of ECT, with the ECT
affiliate designated as the general partner. The purpose of the partnership is
to invest in a diversified portfolio of energy related assets. See "The
Merger."

                                  serving as the Exchange Agent in connection
                                  with the Exchange Offer.
 
                               THE EXCHANGE NOTES
 
  The Exchange Offer applies to $110,000,000 aggregate principal amount of the
Private Notes. The form and terms of the Exchange Notes are the same as the
form and terms of the Private Notes except that (i) the Exchange Notes will
bear the Series B designation, (ii) the Exchange Notes will have been
registered under the Securities Act and, therefore, the Exchange Notes will not
bear legends restricting the transfer thereof and (iii) holders of the Exchange
Notes will not be entitled to certain rights of holders of the Private Notes
under the Registration Rights Agreement, which rights will terminate upon
consummation of the Exchange Offer. The Exchange Notes will evidence the same
indebtedness as the Private Notes (which they replace) and will be issued
under, and be entitled to the benefits of, the Indenture. For further
information and for definitions of certain capitalized terms used below, see
"Description of Exchange Notes."
 
ISSUER..........................  Coda Energy, Inc.
 
SECURITIES OFFERED..............  $110 million principal amount of 10 1/2% Se-
                                  ries B Senior Subordinated Notes due 2006.

                                  annual rate of 10 1/2% and will be payable in
                                  cash semiannually in arrears on April 1 and
                                  October 1 of each year, commencing October 1,
                                  1996. See "The Exchange Offer--Interest on
                                  the Exchange Notes."
 
RANKING.........................  The Exchange Notes will be general, unsecured
                                  obligations of Coda, will be subordinated in
                                  right of payment to all Senior Debt of Coda,
                                  and will be senior in right of payment to all
                                  future subordinated debt of Coda. The claims
                                  of the holders of the Exchange Notes will be
                                  subordinated to Senior Debt, which, as of
                                  March 31, 1996, was $81.8 million. On May 1,
                                  1996, the Company redeemed all its outstand-
                                  ing 12% Senior Subordinated Debentures due
                                  2000, which resulted in a reduction in Senior
                                  Debt of approximately $1.2 million. See "Cap-
                                  italization."

                                  Coda's current subsidiaries and future Re-
                                  stricted Subsidiaries. The Subsidiary Guaran-

                                  in the name of a nominee of the Depositary.

                                  resenting the Exchange Notes will be shown

                                  only through, records maintained by the De-
                                  positary and its participants. Except as de-
                                  scribed herein, Exchange Notes in certifi-
                                  cated form will not be issued in exchange for

                                  nants that, among other things, limit the
                                  ability of Coda and its Restricted Subsidiar-
                                  ies to incur additional indebtedness and is-

                                  nants."
 
MANDATORY REDEMPTION............  None.
 
OPTIONAL REDEMPTION.............  Except as described below, the Notes are not
                                  redeemable at Coda's option prior to April 1,
                                  2001. After April 1, 2001, the Notes will be
                                  subject to redemption at the option of Coda,
                                  in whole or in part, at the redemption prices
                                  set forth herein, plus accrued and unpaid in-
                                  terest thereon to the applicable redemption
                                  date.
 
                                  In addition, until March 12, 1999, up to
                                  $27.5 million in aggregate principal amount
                                  of Notes will be redeemable at the option of
                                  Coda on any one or more occasions from the
                                  net proceeds of an offering of common equity
                                  of Coda, at a price of 110.5% of the aggre-
                                  gate principal amount of the Notes, together
                                  with accrued and unpaid interest thereon to
                                  the date of the redemption; provided, howev-
                                  er, that at least $82.5 million in aggregate
                                  principal amount of Notes must remain out-
                                  standing immediately after the occurrence of
                                  such redemption; provided, further, that any
                                  such redemption shall occur within 75

                                  days of the date of the closing of such of-
                                  fering of common equity. See "Description of
                                  Exchange Notes--Optional Redemption."
 
CHANGE OF CONTROL...............  In the event of a Change of Control, holders
                                  of the Notes will have the right to require
                                  Coda to repurchase their Notes, in whole or
                                  in part, at a price in cash equal to 101% of
                                  the aggregate principal amount thereof, plus
                                  accrued and unpaid interest thereon to the
                                  date of repurchase. The Indenture will re-
                                  quire that, prior to such a repurchase but in
                                  any event within 90 days of such Change of
                                  Control, Coda must either repay all Senior
                                  Debt or obtain any required consent to such
                                  repurchase. The degree to which the Company
                                  is leveraged at the time of a Change of Con-
                                  trol could prevent it from repaying outstand-
                                  ing Senior Debt (or otherwise obtaining the
                                  consent of holders of Senior Debt to make a
                                  Change of Control Offer) which would prohibit
                                  Coda from repurchasing Notes tendered to it
                                  upon such Change of Control. In such case,
                                  Coda's failure to purchase the Notes would
                                  constitute an Event of Default under the In-
                                  denture. In such circumstances, the subordi-
                                  nation provisions in the Indenture would
                                  likely restrict payments to the Holders of
                                  Notes by either Coda or the Guarantors. Coda
                                  is not required to make a Change of Control
                                  Offer if a third party makes a Change of Con-
                                  trol Offer in compliance with the Indenture
                                  and purchases all Notes validly tendered and
                                  not withdrawn under such Change of Control
                                  Offer. See "Description of Exchange Notes--
                                  Repurchase at the Option of Holders--Change
                                  of Control."
 
                                  RISK FACTORS
 
  Prior to making an investment decision, holders of the Private Notes should
consider all of the information set forth in this Prospectus and should
evaluate the considerations set forth in "Risk Factors" beginning on page 18
hereof.

                         SUMMARY FINANCIAL INFORMATION
 
  The following table sets forth certain historical and pro forma operating
and financial data of the Company. See "Selected Historical and Pro Forma
Financial Data" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations." The historical data should be read in
conjunction with the Historical Financial Statements and the notes thereto
included elsewhere in this Prospectus. The Company acquired significant
producing oil and natural gas properties in all the periods presented which
affect the comparability of the historical financial and operating data for
the periods presented. As a result of the Merger, JEDI acquired Coda effective
February 16, 1996. The Merger has been accounted for using the purchase method
of accounting. As such, JEDI's cost of acquiring Coda has been allocated to
the assets and liabilities acquired based on estimated fair values. As a
result, the Company's financial position and operating results subsequent to
the date of the Merger reflect a new basis of accounting and are not
comparable to prior periods. The pro forma information should be read in
conjunction with the Pro Forma Condensed Financial Statements and notes
thereto included elsewhere in this Prospectus. Neither the historical results
nor the pro forma results are necessarily indicative of the Company's future
operations or financial results.

- --------
 (1) Reflects the pro forma effect of the Snyder Acquisition, the Merger, the
     sale of the Private Notes and the application of the proceeds thereof to
     retire the JEDI Debt and pay down a portion of the outstanding borrowings
     under the Credit Agreement. See the Company's Pro Forma Condensed
     Financial Statements, included elsewhere in this Prospectus, for a
     discussion of the preparation of this data. The pro forma combined results
     of operations exclude a charge of approximately $53.3 million (net of
     related deferred taxes of $30.0 million) representing the adjustment of
     the carrying value of proved oil and gas properties pursuant to the full
     cost method of accounting. Such adjustment has been included in the
     historical results of operations of the Company in the period the Merger
     was consummated. Pro forma net cash provided by operating activities was
     obtained by adjusting the historical amount for the pro forma changes in
     oil and natural gas sales, oil and natural gas production expenses,
     general and administrative expenses and interest expense. The exchange of
     the Exchange Notes for the Private Notes would have no effect on the pro
     forma information. See also "Use of Proceeds" and "Capitalization."
 (2) The Company ceased its third party natural gas marketing operations in
     1992. The Company acquired Taurus in April 1994.
 (3) Total costs and expenses for the periods ended February 16, 1996 and March
     31, 1996 include approximately $3.2 million of stock option compensation
     expense and $83.3 million for the writedown of oil and gas properties,
     respectively.
 (4) For purposes of computing the ratio of earnings to fixed charges, earnings
     consist of income before income taxes plus fixed charges. Fixed charges
     consist of interest expense. For the periods ended December 31, 1992,
     February 16, 1996 and March 31, 1996, earnings were inadequate to cover
     fixed charges by approximately $1.1 million, $1.8 million and $83.1
     million, respectively. Pro forma earnings for the year ended December 31,
     1995 and three months ended March 31, 1996, would have been inadequate to
     cover fixed charges by approximately $7.1 million and $283,000,
     respectively.
 (5) In addition to cash flows provided by operating activities, the Company
     also has significant cash flows which are provided by or used in investing
     and financing activities. See "Management's Discussion and Analysis of
     Financial Condition and Results of Operations--Liquidity and Capital
     Resources," "--Effects of the Merger, the Sale of the Private Notes and
     the Exchange Offer--Credit Agreement" and the Historical Financial
     Statements of the Company.
 (6) EBITDA is calculated as operating income before interest, income taxes,
     depletion, depreciation and amortization. EBITDA is not a measure of cash
     flow as determined by generally accepted accounting principles ("GAAP").
     The Company has included information concerning EBITDA because EBITDA is a
     measure used by certain investors in determining the Company's historical
     ability to service its indebtedness. EBITDA should not be considered as an
     alternative to, or more meaningful than, net income or cash flows as
     determined in accordance with GAAP as an indicator of the Company's
     operating performance or liquidity. Debt/EBITDA is calculated only for the
     historical annual periods. EBITDA for the period ended February 16, 1996
     is net of approximately $3.2 million of stock option compensation expense
     which is a non-cash charge.
 (7) Production costs in 1992 were relatively high because two of the Company's
     waterflood operations and the costs associated therewith commenced in 1992
     but the anticipated response of increased oil production did not commence
     to any material degree until 1993.
 (8) In 1994, the Company acquired Diamond Energy Operating Company and a
     related company which have since merged ("Diamond") in a transaction
     accounted for as a pooling of interests. Reserve data was prepared by the
     Company's independent consulting engineers except that such estimates
     related to the reserves of Diamond as of December 31, 1991, 1992 and 1993
     were prepared by Diamond's in-house engineers.
 (9) The annual reserve replacement ratio is calculated by dividing total
     reserve additions (purchases of reserves, extensions and revisions) on a
     Boe basis for the year by actual production on a Boe basis for such year
     with the acquisition of Diamond treated as a purchase instead of a
     pooling.
(10) The estimated reserve life is calculated by dividing the proved reserves
     on a Boe basis by the forecasted production on a Boe basis for the 12
     months following the date indicated (both as estimated by the Company's
     independent consulting engineers as of December 31 of each year).
(11) Discounted at an annual rate of 10%. See "Glossary" included elsewhere in
     this Prospectus for the definition of "present value of estimated future
     net revenues." The Company believes that the present value of estimated
     future net revenues before income taxes, while not in accordance with
     generally accepted accounting principles, is an important financial
     measure used by investors in independent oil and natural gas producers for
     evaluating the relative significance of oil and natural gas properties and
     acquisitions. The present value of estimated future net revenues should
     not be construed as an alternative to the Standardized Measure, as
     determined in accordance with generally accepted accounting principles.
(12) Represents after tax present value of estimated future net revenues.

                                 RISK FACTORS
 
  Prior to making an investment decision, prospective investors should
consider fully, together with the other information contained in this
Prospectus, the following factors. This Prospectus contains forward looking
statements of the Company. The Company wishes to caution prospective investors
that the following important factors could affect the Company's actual results
in the future.
 
TENDERING PRIVATE NOTES
 
  Exchange Notes will be issued in exchange for Private Notes only after
timely receipt by the Exchange Agent of such Private Notes, a properly
completed and duly executed Letter of Transmittal and all other required
documentation. Therefore, holders of Private Notes desiring to tender such
Private Notes in exchange for Exchange Notes should allow sufficient time to
ensure timely delivery. Neither the Exchange Agent nor the Company is under
any duty to give notification of defects or irregularities with respect to
tenders of Private Notes for exchange. In addition, any holder of Private
Notes who tenders in the Exchange Offer for the purpose of participating in a
distribution of the Exchange Notes will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. Each broker-dealer that receives
Exchange Notes for its own account in exchange for Private Notes, where such
Private Notes were acquired by such broker-dealer as a result of market-making
activities or any other trading activities, must acknowledge that it will
deliver a prospectus in connection with any resale of such Exchange Notes. See
"The Exchange Offer."
 
CONSEQUENCES OF NOT EXCHANGING PRIVATE NOTES
 
  Private Notes that are not exchanged for Exchange Notes pursuant to the
Exchange Offer will continue to be deemed restricted securities under the
Securities Act and subject to the restrictions on transfer of such Private
Notes a set forth in the legend thereon. Accordingly, the Private Notes may
not be offered or sold, unless registered under the Securities Act or sold
pursuant to an exemption from, or in a transaction not subject to, the
Securities Act and applicable state securities laws. Furthermore, any and all
registration rights under the Registration Rights Agreement held by holders of
Private Notes eligible to participate in the Exchange Offer will be
extinguished as a result of the completion of the Exchange Offer. To the
extent that Private Notes are tendered and accepted in the Exchange Offer, the
trading market for untendered and tendered but unaccepted Private Notes could
be adversely affected due to the limited amount, or "float," of the Private
Notes that are expected to remain outstanding following the Exchange Offer.
Generally, a lower "float" of a security could result in less demand to
purchase such security and could, therefore, result in lower prices for such
security. For the same reason, to the extent that a large amount of Private
Notes are not tendered or are tendered and not accepted in the Exchange Offer,
the trading market for the Exchange Notes could be adversely affected. See
"The Exchange Offer--Consequences of Not Exchanging Private Notes."
 
LEVERAGE
 
  The Company incurred substantial indebtedness in connection with the Merger
and as a result, the Company is highly leveraged. As of March 31, 1996, the
Company had total indebtedness of approximately $191.8 million and
stockholders' equity (including preferred stock) of approximately $60.5
million. Also, after giving pro forma effect to the Merger and the related
financing transactions, including the sale of the Private Notes, the Company's
earnings would have been insufficient to cover its fixed charges by
approximately $7.1 million for 1995. Pro forma interest expense for 1995 would
have been approximately $18.6 million. The Company intends to incur additional
indebtedness in the future as it executes its acquisition and exploitation
strategy. See "--Ability to Obtain Capital to Finance Acquisitions,"
"Capitalization" and Pro Forma Condensed Financial Statements.
 
                                      18
<PAGE>
 
  The Company's ability to make scheduled payments of principal of, or to pay
interest on, or to refinance its indebtedness (including the Notes) depends on
its future performance, which, to a certain extent, is subject to general
economic, financial, competitive, legislative, regulatory and other factors
beyond its control, as well as to the prevailing market prices for oil and
natural gas. There can be no assurance that the Company's business will
generate sufficient cash flow from operations or that future bank credit will
be available in an amount sufficient to enable the Company to service its
indebtedness, including the Notes, or make necessary capital expenditures. In
addition, the Company anticipates that it is likely to find it necessary to
refinance a portion of the principal amount of the Notes at or prior to their
maturity. However, there can be no assurance that the Company will be able to
obtain financing to complete a refinancing of the Notes. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."
 
  The degree to which the Company is leveraged as a result of the sale of the
Private Notes could have important consequences to holders of the Notes,
including, but not limited to, the following: (i) a substantial portion of the
Company's cash flow from operations will be required to be dedicated to debt
service and will not be available for other purposes; (ii) the Company's
ability to obtain additional financing in the future could be limited; (iii)
certain of the Company's borrowings are at variable rates of interest, which
could result in higher interest expense in the event of increases in interest
rates; and (iv) the Company will be subject to a variety of restrictive
covenants and the failure of the Company to comply with such covenants could
result in events of default which, if not cured or waived, could have a
material adverse effect on the Company and its ability to make payments of
principal of, and interest on, the Notes. See "Description of Exchange Notes"
and "Description of Other Indebtedness."
 
ACQUISITION RISKS; DEPLETION OF RESERVES
 
  The Company's strategy is to increase oil and natural gas reserves and cash
flow by selectively acquiring and exploiting producing oil and natural gas
properties, primarily in the mid-continent region of the United States, rather
than engaging in exploratory drilling. The Company's business strategy assumes
that major integrated oil companies and independent oil companies will
continue to divest many of their domestic oil and natural gas properties.
There can be no assurance, however, that such divestitures will continue or
that the Company will be able to acquire such properties at acceptable prices
or develop additional reserves in the future. If such acquisition
opportunities should cease to exist, the Company may be required to alter its
business strategy.
 
  Although the Company performs a review of the properties proposed to be
acquired, such reviews are subject to uncertainties. It is not feasible to
review in detail every individual property involved in each acquisition.
Ordinarily, the Company will focus its review efforts on the higher-valued
properties. However, even a detailed review of all properties and records may
not necessarily reveal existing or potential problems; nor will it permit the
Company to become sufficiently familiar with the properties to assess fully
their deficiencies and capabilities. Inspections are not routinely performed
on every well, and many potential problems, for example, mechanical integrity
of equipment and environmental conditions that may require significant
remedial expenditures, are not necessarily detectable even when an inspection
is undertaken. See "Business--Strategy."
 
  Producing oil and natural gas reservoirs are, in general, characterized by
declining production rates. The decline rate varies depending upon reservoir
characteristics and other factors. The Company's future oil and natural gas
reserves and production, and, therefore, cash flow and income, are highly
dependent upon the Company's level of success in exploiting its current
reserves and acquiring or finding additional reserves. Without reserve
additions in excess of production through acquisition or exploitation and
development activities, the Company's reserves and production will decline
over the long term. There can be no assurance that the Company will be able to
find and develop or acquire additional reserves to replace its current and
future production.

ABILITY TO OBTAIN CAPITAL TO FINANCE ACQUISITIONS
 
  The Company's strategy of acquiring producing oil and natural gas properties
is dependent upon its ability to obtain financing for any such acquisitions.
The Company expects to utilize its Credit Agreement (the "Credit Agreement")
with NationsBank of Texas, N.A. ("NationsBank"), individually and as agent,
and certain other financial institutions as lenders, to borrow 60% to 100% of
the funds required on any given transaction. The Credit Agreement limits the
amounts the Company may borrow thereunder to amounts, determined by the
lenders in their sole discretion, based upon projected net revenues from the
Company's oil and natural gas properties and gas gathering and processing
assets and restricts the amounts the Company may borrow under other credit
facilities. The lenders can adjust the borrowings permitted to be outstanding
under the Credit Agreement semiannually. The lenders require that outstanding
borrowings in excess of the borrowing limit be repaid ratably over a period no
longer than six months. No assurances can be given that the Company will be
able to make any such mandatory principal payments required by the lenders.
 
  Any future acquisition by the Company requiring bank financing in excess of
the amount then available under the Credit Agreement will depend upon the
lenders' evaluations of the properties proposed to be acquired. For a
description of the Credit Agreement and its principal terms and conditions,
see "Description of Other Indebtedness."
 
VOLATILITY OF OIL, NATURAL GAS AND NATURAL GAS LIQUIDS PRICES
 
  The Company's financial results are significantly impacted by the price
received for the Company's oil, natural gas and natural gas liquids
production. Historically, the markets for oil, natural gas and natural gas
liquids have been volatile and are likely to continue to be volatile in the
future. Prices for oil, natural gas and natural gas liquids are subject to
wide fluctuation in response to market uncertainty, changes in supply and
demand and a variety of additional factors, all of which are beyond the
control of the Company. These factors include domestic and foreign political
conditions, the overall level of supply of and demand for oil, natural gas and
natural gas liquids, the price of imports of oil and natural gas, weather
conditions, the price and availability of alternative fuels and overall
economic conditions. The Company's future financial condition and results of
operations will be dependent, in part, upon the prices received for the
Company's oil and natural gas production, as well as the costs of acquiring,
finding, developing and producing reserves. If oil and natural gas prices fall
materially below their current levels, the availability of funds and the
Company's ability to repay outstanding amounts under its Credit Agreement and
the Notes could be materially adversely affected. See "--Ability to Obtain
Capital" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
RELIANCE ON ESTIMATES OF PROVED RESERVES AND FUTURE NET REVENUES
 
  There are numerous uncertainties in estimating quantities of proved reserves
and in projecting future rates of production and the timing of development
expenditures, including many factors beyond the control of the Company. The
reserve data set forth in this Prospectus are only estimates. Reserve
estimates are imprecise and may be expected to change as additional
information becomes available. Furthermore, estimates of oil and gas reserves,
of necessity, are projections based on engineering data, and there are
uncertainties inherent in the interpretation of such data as well as the
projection of future rates of production and the timing of development
expenditures. Reserve engineering is a subjective process of estimating
underground accumulations of oil and natural gas that cannot be exactly
measured, and the accuracy of any reserve estimate is a function of the
quality of available data and of engineering and geological interpretation and
judgment. Accordingly, estimates of the economically recoverable quantities of
oil and natural gas attributable to any particular group of properties,
classifications of such reserves based on risk of recovery and estimates of
the future net cash flows expected therefrom prepared by different engineers
or by the same engineers at different
 
                                      20
<PAGE>
 
times may vary substantially. There also can be no assurance that the reserves
set forth herein will ultimately be produced or that the proved undeveloped
reserves will be developed within the periods anticipated. It is likely that
variances from the estimates will be material. In addition, the estimates of
future net revenues from proved reserves of the Company and the present value
thereof are based upon certain assumptions about future production levels,
prices and costs that may not be correct. The Company emphasizes with respect
to the estimates prepared by independent petroleum engineers that the
discounted future net cash flows should not be construed as representative of
the fair market value of the proved oil and natural gas properties belonging
to the Company, since discounted future net cash flows are based upon
projected cash flows which do not provide for changes in oil and natural gas
prices or for escalation of expenses and capital costs. The meaningfulness of
such estimates is highly dependent upon the accuracy of the assumptions upon
which they were based. Actual results are likely to differ materially from the
results estimated. Prospective investors in the Exchange Notes are cautioned
not to place undue reliance on the reserve data included in this Prospectus.
 
DRILLING AND OPERATIONAL RISKS
 
  The Company's oil and natural gas business is also subject to all of the
operating risks associated with the drilling for and production and secondary
recovery of oil and natural gas, including, but not limited to, uncontrollable
flows of oil, natural gas, brine or well fluids (including fluids used in
waterflood activities) into the environment (including groundwater
contamination), fires, explosions, pollution and other risks, any of which
could result in substantial losses to the Company. The natural gas gathering
and processing business is also subject to certain of these risks, including
fires, explosions and environmental contamination. Although the Company
carries insurance at levels which it believes are consistent with industry
practices, it is not fully insured against all risks. Losses and liabilities
arising from uninsured and underinsured events could have a material adverse
effect on the financial condition and operations of the Company. See
"Business--Exploitation and Development Activities."
 
  There are certain risks associated with secondary recovery operations,
especially the use of waterflooding techniques, and drilling activities in
general. Waterflooding involves significant capital expenditures and
uncertainty as to the total amount of secondary reserves that can be
recovered. In waterflood operations, there is generally a delay between the
initiation of water injection into a formation containing hydrocarbons and any
increase in production that may result. The unit production costs per Boe of
waterflood projects are generally higher during the initial phases of such
projects due to the purchase of injection water and related costs, as well as
during the later stages of the life of the project. The degree of success, if
any, of any secondary recovery program depends on a large number of factors,
including the porosity of the formation, the technique used and the location
of injector wells. Drilling activities carry the risk that no commercial
production will be obtained. The cost of drilling, completing and operating
wells is often uncertain, and drilling operations may be curtailed, delayed or
canceled as a result of many factors.
 
SUBORDINATION OF THE NOTES AND GUARANTEES
 
  The Notes and Guarantees will be subordinated in right of payment to all
existing and future Senior Debt of the Company, which includes all
indebtedness under the Credit Agreement. As of March 31, 1996, the Company had
$81.8 million in Senior Debt and $35.0 million available for borrowing under
the Credit Agreement. In the event of a liquidation, dissolution,
reorganization, bankruptcy or any similar proceeding regarding the Company,
the assets of the Company will be available to pay obligations on the Notes
only after Senior Debt of the Company has been paid in full. Accordingly,
there may not be sufficient funds remaining to pay amounts due on all or any
of the Notes. See "Description of Exchange Notes--Subordination."
 
                                      21
<PAGE>
 
  The Company's oil and natural gas properties will not serve as collateral
under the Credit Agreement unless certain events occur. The Company will
provide the lenders with first lien deeds of trust on substantially all of the
Company's oil and natural gas properties. The lenders have agreed, however,
that the mortgages will not be effective and the lenders will not file the
deeds of trust on the oil and natural gas assets unless (i) 80% of any
outstanding borrowings in excess of the borrowing limit is not repaid within a
90 day period, (ii) cash collateral securing a hedging transaction exceeds 20%
of the borrowing limit or (iii) an event of default or a material adverse
event, as defined in the Credit Agreement, occurs.
 
  In addition to being subordinated to all existing and future Senior Debt of
the Company, the Notes and Guarantees will not be secured by any of the
Company's assets.
 
GOVERNMENT LAWS AND REGULATIONS
 
  The Company's operations are affected from time to time in varying degrees by
political developments and federal and state laws and regulations. In
particular, oil and natural gas production, operations and economics are or
have been affected by price controls, taxes and other laws relating to the oil
and natural gas industry, by changes in such laws and by changes in
administrative regulations. The Company cannot predict how existing laws and
regulations may be interpreted by enforcement agencies or court rulings,
whether additional laws and regulations will be adopted, or the effect such
changes may have on its business or financial condition. See "Business--
Regulation."
 
ENVIRONMENTAL REGULATIONS
 
  The Company's operations are subject to complex and constantly changing
environmental laws and regulations adopted by federal, state and local
governmental authorities. The Company believes that compliance with such laws
has had no material adverse effect upon the Company's operations to date, and
that the cost of such compliance has not been material. Nevertheless, the
discharge of oil, natural gas or other pollutants into the air, soil or water
may give rise to liabilities on the part of the Company to the government and
third parties and may require the Company to incur costs of remediation.
Additionally, since a significant portion of the Company's reserves are
dependent upon waterflood operations, any change in produced water disposal
requirements or injection well permitting could have a material adverse effect
on the financial conditions and operations of the Company. Moreover, from time
to time the Company has agreed to indemnify both sellers of producing
properties from whom the Company acquires reserves and purchasers of properties
from the Company against certain liabilities for environmental claims
associated with the properties being purchased or sold by the Company. No
assurance can be given that existing environmental laws or regulations, as
currently interpreted or reinterpreted in the future, or future laws or
regulations, will not materially adversely affect the Company's operations and
financial condition or that material indemnity claims will not arise against
the Company with respect to properties acquired or sold by the Company. See
"Business--Environmental Matters."
 
USE AND RISKS OF HEDGING TRANSACTIONS
 
  The Company has in the past and may in the future enter into oil and natural
gas hedging transactions. While intended to reduce the effects of volatility of
the price of oil and natural gas, such transactions may limit potential gains
by the Company if oil and natural gas prices were to rise substantially over
the price established by the hedge. If the Company is required to maintain cash
collateral on hedging transactions which exceeds 20% of the Company's borrowing
limit under its Credit Agreement, the Company may be required by the lenders to
pledge substantially all of its oil and natural gas properties as collateral
under the Credit Agreement. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Results of Operations" and Note
7 of Notes to Consolidated Financial Statements.
 
                                       22
<PAGE>
 
CONFLICTS OF INTEREST
 
  Enron Corp. ("Enron") is the parent of ECT and accordingly may be deemed to
control indirectly both JEDI and the Company. Enron and certain of its
subsidiaries and other affiliates collectively participate in nearly all
phases of the oil and natural gas industry and are, therefore, competitors of
the Company. In addition, ECT and JEDI have provided, and may in the future
provide, and ECT Securities Corp. has assisted, and may in the future assist,
in arranging, financing to non-affiliated participants in the oil and natural
gas industry who are or may become competitors of the Company.
 
  ECT, the Company, JEDI and the Management Group have entered into a Business
Opportunity Agreement (the "Business Opportunity Agreement") that is intended
to make clear that Enron and its affiliates have no duty to make business
opportunities available to the Company in most circumstances. The Business
Opportunity Agreement also provides that ECT and its affiliates may pursue
certain business opportunities to the exclusion of the Company. Accordingly,
the Business Opportunity Agreement may limit the business opportunities
available to the Company. In addition, pursuant to the Business Opportunity
Agreement there may be circumstances in which the Company will be required to
offer business opportunities to certain affiliates of Enron. If an Enron
affiliate is offered such an opportunity and decides to pursue it, the Company
may be unable to pursue it.
 
  In addition, the Company has in the past marketed a material portion of its
crude oil and natural gas production through certain Enron trading
subsidiaries and will likely continue to do so in the future. During 1994 and
1995, sales of oil and natural gas to EOTT Energy Operating Limited
Partnership (a subsidiary of Enron) accounted for 22% and 18%, respectively,
of the Company's consolidated revenues. The Indenture will not prohibit the
Company from conducting business with Enron and its subsidiaries and
affiliates, but will provide that certain requirements must be satisfied in
order for the Company to transact such business. See "Description of Exchange
Notes--Certain Covenants" and "Certain Transactions."
 
COMPETITION
 
  The Company encounters substantial competition in acquiring properties,
marketing oil and natural gas and securing trained personnel. Many competitors
have financial resources, staffs and facilities which substantially exceed
those of the Company. See "Business--Markets and Competition."
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company believes that its operations are dependent to a significant
extent upon its senior management. The loss of the services of a significant
number of these key personnel could have a material adverse effect upon the
Company. The Credit Agreement contains a covenant that requires the continued
employment of certain members of management and requires that certain officers
of the Company maintain specified levels of equity ownership in the Company.
See "Management."
 
PAYMENT UPON A CHANGE OF CONTROL
 
  Upon the occurrence of a Change of Control, each holder of the Notes may
require the Company to repurchase all or a portion of such holder's Notes at
101% of the principal amount of the Notes, together with accrued and unpaid
interest and Liquidated Damages, if any, to the date of repurchase. The
Indenture will require that prior to such a repurchase, the Company must
either repay all outstanding Senior Debt or obtain any required consents to
such repurchase. Further, under the Credit Agreement, an event of default is
deemed to occur if (i) JEDI, Enron, CalPERS or any wholly owned subsidiary of
either Enron or CalPERS ceases to own greater than 50% of every class of
issued and outstanding capital stock of the Company (on either an undiluted or
fully diluted basis), (ii) JEDI, Enron, CalPERS or any wholly owned subsidiary
of either Enron or CalPERS ceases to own a majority of the outstanding capital
stock of the Company (on either an undiluted or fully diluted basis) having
ordinary
 
                                      23
<PAGE>
 
voting rights for the election of directors or (iii) certain officers cease to
serve in their current positions. In such circumstances, the lenders could
require the repayment of the borrowings under the Credit Agreement. Thus, if a
Change of Control were to occur, the Company may not have the financial
resources to repay all of the Senior Debt, the Notes and the other
indebtedness that would become payable upon the occurrence of such Change of
Control. See "Description of Exchange Notes--Repurchase at the Option of
Holders--Change of Control."
 
FRAUDULENT CONVEYANCE
 
  Management of the Company believes that the indebtedness represented by the
Notes and the Guarantees was incurred for proper purposes and in good faith,
and that, based on present forecasts, asset valuations and other financial
information, after the consummation of the sale of the Private Notes and the
Exchange Offer, the Company will be solvent, will have sufficient capital for
carrying on its business and will be able to pay its debts as they mature.
See, however, "--Leverage." Notwithstanding management's belief, however, if a
court of competent jurisdiction in a suit by an unpaid creditor or a
representative of creditors (such as a trustee in bankruptcy or a debtor-in-
possession) were to find that, at the time of the incurrence of such
indebtedness, the Company or any of the Guarantors were insolvent, were
rendered insolvent by reason of such incurrence, were engaged in a business or
transaction for which its remaining assets constituted unreasonably small
capital, intended to incur, or believed that it would incur, debts beyond its
ability to pay such debts as they matured, or intended to hinder, delay or
defraud its creditors, and that the indebtedness was incurred for less than
reasonably equivalent value, then such court could, among other things, (i)
void all or a portion of the Company's or the Guarantors' obligations to the
holders of the Notes, the effect of which would be that the holders of the
Notes may not be repaid in full and/or (ii) subordinate the Company's or the
Guarantors' obligations to the holders of the Notes to other existing and
future indebtedness of the Company to a greater extent than would otherwise be
the case, the effect of which would be to entitle such other creditors to be
paid in full before any payment could be made on the Notes or the Guarantees.
 
LACK OF PUBLIC MARKET FOR THE NOTES; RESTRICTIONS ON RESALES
 
  As of the date of this Prospectus, the only registered holder of the Private
Notes is Cede & Co., as nominee of DTC. The Company believes that, as of the
date of this Prospectus, such holder is not an "affiliate" (as such term is
defined in Rule 405 under the Securities Act) of the Company. Prior to the
offering of the Private Notes, there had been no existing trading market for
the Notes, and there can be no assurance regarding the future development of a
market for the Notes, or the ability of holders of the Notes to sell their
Notes or the price at which such holders may be able to sell their Notes. If
such a market were to develop, the Notes could trade at prices that may be
higher or lower than the initial offering price of the Private Notes depending
on many factors, including prevailing interest rates, the Company's operating
results and the market for similar securities. The Initial Purchasers (other
than ECT Securities Corp.) have advised the Company that they currently intend
to make a market in the Notes. The Purchasers are not obligated to do so,
however, and any market-making with respect to the Notes may be interrupted or
discontinued at any time without notice. In addition, such market making
activity may be limited during the Exchange Offer and the pendency of the
Shelf Registration Statement (as defined in the Registration Rights
Agreement), if any. There can be no assurance as to the liquidity of any
trading market for the Notes or that an active public market for the Notes
will develop. The Private Notes are eligible for trading in the Private
Offerings, Resales and Trading through Automatic Linkages (PORTAL) Market. The
Company does not intend to apply for listing or quotation of the Notes on any
securities exchange or stock market.

                              THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
  The Private Notes were sold by the Company on March 18, 1996 (the "Closing
Date") to the Initial Purchasers pursuant to the Purchase Agreement. The
Initial Purchasers subsequently sold the Private Notes to (i) "qualified
institutional buyers" ("QIBs"), as defined in Rule 144A under the Securities
Act ("Rule 144A"), in reliance on Rule 144A and (ii) a limited number of
institutional "accredited investors" ("Accredited Institutions"), as defined
in Rule 501(a)(1), (2), (3) or (7) under the Securities Act. As a condition to
the sale of the Private Notes, the Company and the Initial Purchasers entered
into the Registration Rights Agreement on March 18, 1996. Pursuant to the
Registration Rights Agreement, the Company agreed that it would (i) file with
the Commission a Registration Statement under the Securities Act with respect
to the Exchange Notes within 30 days after the Closing Date and (ii) use its
best efforts to cause such Registration Statement to become effective under
the Securities Act within 90 days after the Closing Date. A copy of the
Registration Rights Agreement has been filed as an exhibit to the Registration
Statement. The Registration Statement is intended to satisfy certain of the
Company's obligations under the Registration Rights Agreement and the Purchase
Agreement.
 
RESALE OF THE EXCHANGE NOTES
 
  With respect to the Exchange Notes, based upon an interpretation by the
staff of the Commission set forth in certain no-action letters issued to third
parties, the Company believes that a holder (other than (i) a broker-dealer
who purchases such Exchange Notes directly from the Company to resell pursuant
to Rule 144A or any other available exemption under the Securities Act or (ii)
any such holder that is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act) who exchanges Private Notes for Exchange
Notes in the ordinary course of business and who is not participating, does
not intend to participate, and has no arrangement with any person to
participate, in a distribution of the Exchange Notes, will be allowed to
resell Exchange Notes to the public without further registration under the
Securities Act and without delivering to the purchasers of the Exchange Notes
a prospectus that satisfies the requirements of Section 10 of the Securities
Act. However, if any holder acquires Exchange Notes in the Exchange Offer for
the purpose of distributing or participating in the distribution of the
Exchange Notes or is a broker-dealer, such holder cannot rely on the position
of the staff of the Commission enumerated in certain no-action letters issued
to third parties and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction,
unless an exemption from registration is otherwise available. Each broker-
dealer that receives Exchange Notes for its own account in exchange for
Private Notes, where such Private 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. 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 Private Notes where such Private Notes were acquired by such
broker-dealer as a result of market-making or other trading activities.
Pursuant to the Registration Rights Agreement, the Company has agreed to make
this Prospectus, as it may be amended or supplemented from time to time,
available to broker-dealers for use in connection with any resale for a period
of one year after the date the Registration Statement is declared effective.
See "Plan of Distribution."
 
TERMS OF THE EXCHANGE OFFER
 
  Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Private
Notes validly tendered and not withdrawn prior to the Expiration Date. The
Company will issue $1,000 principal amount of Exchange Notes in
 
                                      25
<PAGE>
 
exchange for each $1,000 principal amount of outstanding Private Notes
surrendered pursuant to the Exchange Offer. Private Notes may be tendered only
in integral multiples of $1,000.
 
  The form and terms of the Exchange Notes are the same as the form and terms
of the Private Notes except that (i) the Exchange Notes will bear a Series B
designation, (ii) the Exchange Notes will have been registered under the
Securities Act and, therefore, the Exchange Notes will not bear legends
restricting the transfer thereof and (iii) holders of the Exchange Notes will
not be entitled to certain rights of holders of the Private Notes under the
Registration Rights Agreement, which rights will terminate upon consummation
of the Exchange Offer. The Exchange Notes will evidence the same indebtedness
as the Private Notes (which they replace) and will be issued under, and be
entitled to the benefits of, the Indenture, which also authorized the issuance
of the Private Notes, such that both series of Notes will be treated as a
single class of debt securities under the Indenture.
 
  As of the date of this Prospectus, $110,000,000 in aggregate principal
amount of the Private Notes are outstanding and registered in the name of Cede
& Co., as nominee for DTC. Only a registered holder of the Private Notes (or
such holder's legal representative or attorney-in-fact) as reflected on the
records of the Trustee under the Indenture may participate in the Exchange
Offer. There will be no fixed record date for determining registered holders
of the Private Notes entitled to participate in the Exchange Offer.
 
  Holders of the Private Notes do not have any appraisal or dissenters' rights
under the Indenture in connection with the Exchange Offer. The Company intends
to conduct the Exchange Offer in accordance with the provisions of the
Registration Rights Agreement and the applicable requirements of the
Securities Act, the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and the rules and regulations of the Commission thereunder.
 
  The Company shall be deemed to have accepted validly tendered Private Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
of Private Notes for the purposes of receiving the Exchange Notes from the
Company.
 
  Holders who tender Private Notes in 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 Private
Notes pursuant to 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."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
  The term "Expiration Date" shall mean 5:00 p.m., New York City time on July
12, 1996, unless the Company, in its sole discretion, extends the Exchange
Offer, in which case the term "Expiration Date" shall mean the latest date and
time to which the Exchange Offer is extended.
 
  In order to extend the Exchange Offer, the Company will (i) notify the
Exchange Agent of any extension by oral or written notice, (ii) mail to the
registered holders an announcement thereof and (iii) issue a press release or
other public announcement which shall include disclosure of the approximate
number of Private Notes deposited to date, each prior to 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 a
public announcement of any delay, extension, amendment or termination of the
Exchange Offer, the Company shall have no obligation to publish, advertise, or
otherwise communicate any such public announcement, other than by making a
timely release to an appropriate news agency.
 
                                      26
<PAGE>
 
  The Company reserves the right, in its sole discretion, (i) to delay
accepting any Private Notes, (ii) to extend the Exchange Offer or (iii) if any
conditions set forth below under "--Conditions" shall not have been satisfied,
to terminate the Exchange Offer by giving oral or written notice of such
delay, extension or termination to the Exchange Agent. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly
as practicable by oral or written notice thereof to the registered holders. If
the Exchange Offer is amended in a manner determined by the Company to
constitute a material change, the Company will promptly disclose such
amendment by means of a prospectus supplement that will be distributed to the
registered holders of the Private Notes, and the Company will extend the
Exchange Offer for a period of five to ten business days, depending upon the
significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such five to ten
business day period.
 
INTEREST ON THE EXCHANGE NOTES
 
  The Exchange Notes will bear interest at a rate equal to 10 1/2% per annum.
Interest on the Exchange Notes will be payable semiannually in arrears on each
April 1 and October 1, commencing October 1, 1996. Holders of Exchange Notes
will receive interest on October 1, 1996 from and including the date of
initial issuance of the Exchange Notes, plus an amount equal to the accrued
interest on the Private Notes from the date of initial delivery to the date of
exchange thereof for Exchange Notes. Holders of Private Notes that are
accepted for exchange will be deemed to have waived the right to receive any
interest accrued on the Private Notes.
 
PROCEDURES FOR TENDERING
 
  Only a registered holder of Private Notes may tender such Private Notes in
the Exchange Offer. To tender in the Exchange Offer, a holder of Private Notes
must complete, sign and date the Letter of Transmittal, or a facsimile
thereof, have the signatures thereon guaranteed if required by the Letter of
Transmittal, and mail or otherwise deliver such Letter of Transmittal or such
facsimile to the Exchange Agent at the address set forth below under "--
Exchange Agent" for receipt prior to the Expiration Date. In addition, either
(i) certificates for such Private Notes must be received by the Exchange Agent
along with the Letter of Transmittal, (ii) a timely confirmation of a book-
entry transfer (a "Book-Entry Confirmation") of such Private Notes, if such
procedure is available, into the Exchange Agent's account at the Depositary
pursuant to the procedure for book-entry transfer described below, must be
received by the Exchange Agent prior to the Expiration Date or (iii) the
holder must comply with the guaranteed delivery procedures described below.
 
  The tender by a holder that is not withdrawn prior to the Expiration Date
will constitute an agreement between such holder and the Company in accordance
with the terms and subject to the conditions set forth herein and in the
Letter of Transmittal.
 
  THE METHOD OF DELIVERY OF PRIVATE NOTES AND THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK
OF THE HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE
AN OVERNIGHT OR HAND DELIVERY SERVICE, PROPERLY INSURED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR PRIVATE NOTES SHOULD
BE SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
  Any beneficial owner(s) of the Private Notes whose Private Notes are
registered in the name of a broker, dealer, commercial bank, trust company or
other nominee and who wishes to tender should contact the registered holder
promptly and instruct such registered holder to tender on such beneficial
 
                                      27
<PAGE>
 
owner's behalf. If such beneficial owner wishes to tender on such owner's own
behalf, such owner must, prior to completing and executing the Letter of
Transmittal and delivering such owner's Private Notes, either make appropriate
arrangements to register ownership of the Private Notes in such owner's name
or obtain a properly completed bond power from the registered holder. The
transfer of registered ownership may take considerable time.
 
  Signatures on a Letter of Transmittal or a notice of withdrawal described
below (see "--Withdrawal of Tenders"), as the case may be, must be guaranteed
by an Eligible Institution (as defined below) unless the Private Notes
tendered pursuant thereto are tendered (i) by a registered holder who has not
completed the box titled "Special Delivery Instructions" on the Letter of
Transmittal or (ii) for the account of an Eligible Institution. In the event
that signatures on a Letter of Transmittal or a notice of withdrawal, as the
case may be, are required to be guaranteed, such guarantee must be made by a
member firm of a registered national securities exchange or of the National
Association of Securities Dealers, Inc., a commercial bank or trust company
having an office or correspondent in the United States or an "eligible
guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange
Act which is a member of one of the recognized signature guarantee programs
identified in the Letter of Transmittal (an "Eligible Institution").
 
  If the Letter of Transmittal is signed by a person other than the registered
holder of any Private Notes listed therein, such Private Notes must be
endorsed or accompanied by a properly completed bond power, signed by such
registered holder as such registered holder's name appears on such Private
Notes.
 
  If the Letter of Transmittal or any Private Notes 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, evidence satisfactory to the Company of their authority to so act
must be submitted with the Letter of Transmittal.
 
  The Exchange Agent and the Depositary have confirmed that any financial
institution that is a participant in the Depositary's system may utilize the
Depositary's Automated Tender Offer Program to tender Private Notes.
 
  All questions as to the validity, form, eligibility (including time of
receipt), acceptance and withdrawal of tendered Private 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 Private Notes not properly tendered or any Private 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 defects,
irregularities or conditions of tender as to particular Private Notes. The
Company's interpretation of the terms and conditions of the Exchange Offer
(including the instructions in the Letter of Transmittal) will be final and
binding on all parties. Unless waived, any defects or irregularities in
connection with tenders of Private Notes must be cured within such time as the
Company shall determine. Although the Company intends to notify holders of
defects or irregularities with respect to tenders of Private Notes, neither
the Company, the Exchange Agent nor any other person shall incur any liability
for failure to give such notification. Tenders of Private Notes will not be
deemed to have been made until such defects or irregularities have been cured
or waived.
 
  While the Company has no present plan to acquire any Private Notes that are
not tendered in the Exchange Offer or to file a registration statement to
permit resales of any Private Notes that are not tendered pursuant to the
Exchange Offer, the Company reserves the right in its sole discretion to
purchase or make offers for any Private Notes that remain outstanding
subsequent to the Expiration Date or, as set forth below under "--Conditions,"
to terminate the Exchange Offer and, to the extent permitted by applicable
law, purchase Private Notes in the open market, in privately negotiated
 
                                      28
<PAGE>
 
transactions or otherwise. The terms of any such purchases or offers could
differ from the terms of the Exchange Offer.
 
  By tendering, each holder of Private Notes will represent to the Company
that, among other things, (i) Exchange Notes to be acquired by such holder of
Private Notes in connection with the Exchange Offer are being acquired by such
holder in the ordinary course of business of such holder, (ii) such holder has
no arrangement or understanding with any person to participate in the
distribution of the Exchange Notes, (iii) such holder acknowledges and agrees
that any person who is a broker-dealer registered under the Exchange Act or is
participating in the Exchange Offer for the purposes of distributing the
Exchange Notes must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction of the Exchange Notes acquired by such person and cannot rely on
the position of the staff of the Commission set forth in certain no-action
letters, (iv) such holder understands that a secondary resale transaction
described in clause (iii) above and any resales of Exchange Notes obtained by
such holder in exchange for Private Notes acquired by such holder directly
from the Company should be covered by an effective registration statement
containing the selling securityholder information required by Item 507 or Item
508, as applicable, of Regulation S-K of the Commission and (v) such holder is
not an "affiliate," as defined in Rule 405 under the Securities Act, of the
Company. If the holder is a broker-dealer that will receive Exchange Notes for
such holder's own account in exchange for Private Notes that were acquired as
a result of market-making activities or other trading activities, such holder
will be required to acknowledge in the Letter of Transmittal that such holder
will deliver a prospectus in connection with any resale of such Exchange
Notes; however, by so acknowledging and by delivering a prospectus, such
holder will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
RETURN OF PRIVATE NOTES
 
  If any tendered Private Notes are not accepted for any reason set forth in
the terms and conditions of the Exchange Offer or if Private Notes are
withdrawn or are submitted for a greater principal amount than the holders
desire to exchange, such unaccepted, withdrawn or non-exchanged Private Notes
will be returned without expense to the tendering holder thereof (or, in the
case of Private Notes tendered by book-entry transfer into the Exchange
Agent's account at the Depositary pursuant to the book-entry transfer
procedures described below, such Private Notes will be credited to an account
maintained with the Depositary) as promptly as practicable.
 
BOOK-ENTRY TRANSFER
 
  The Exchange Agent will make a request to establish an account with respect
to the Private Notes at the Depositary for purposes of the Exchange Offer
within two business days after the date of this Prospectus, and any financial
institution that is a participant in the Depositary's systems may make book-
entry delivery of Private Notes by causing the Depositary to transfer such
Private Notes into the Exchange Agent's account at the Depositary in
accordance with the Depositary's procedures for transfer. However, although
delivery of Private Notes may be effected through book-entry transfer at the
Depositary, the Letter of Transmittal or facsimile thereof, with any required
signature guarantees and any other required documents, must, in any case, be
transmitted to and received by the Exchange Agent at the address set forth
below under "--Exchange Agent" on or prior to the Expiration Date or pursuant
to the guaranteed delivery procedures described below.
 
GUARANTEED DELIVERY PROCEDURES
 
  Holders who wish to tender their Private Notes and (i) whose Private Notes
are not immediately available or (ii) who cannot deliver their Private Notes,
the Letter of Transmittal or any other required documents to the Exchange
Agent prior to the Expiration Date, may effect a tender if:
 
                                      29
<PAGE>
 
    (a) The tender is made through an Eligible Institution;
 
    (b) Prior to the Expiration Date, the Exchange Agent receives from such
  Eligible Institution a properly completed and duly executed Notice of
  Guaranteed Delivery substantially in the form provided by the Company (by
  facsimile transmission, mail or hand delivery) setting forth the name and
  address of the holder, the certificate number(s) of such Private Notes and
  the principal amount of Private Notes tendered, stating that the tender is
  being made thereby and guaranteeing that, within five New York Stock
  Exchange trading days after the Expiration Date, the Letter of Transmittal
  (or a facsimile thereof), together with the certificate(s) representing the
  Private Notes in proper form for transfer or a Book-Entry Confirmation, as
  the case may be, and any other documents required by the Letter of
  Transmittal, will be deposited by the Eligible Institution with the
  Exchange Agent; and
 
    (c) Such properly executed Letter of Transmittal (or facsimile thereof),
  as well as the certificate(s) representing all tendered Private Notes in
  proper form for transfer and all other documents required by the Letter of
  Transmittal are received by the Exchange Agent within five New York Stock
  Exchange trading days after the Expiration Date.
 
  Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Private Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
  Except as otherwise provided herein, tenders of Private Notes may be
withdrawn at any time prior to the Expiration Date.
 
  To withdraw a tender of Private Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to the Expiration Date. Any such
notice of withdrawal must (i) specify the name of the person having deposited
the Private Notes to be withdrawn (the "Depositor"), (ii) identify the Private
Notes to be withdrawn (including the certificate number or numbers and
principal amount of such Private Notes) and (iii) be signed by the holder in
the same manner as the original signature on the Letter of Transmittal by
which such Private Notes were tendered (including any required signature
guarantees). All questions as to the validity, form and eligibility (including
time of receipt) of such notices will be determined by the Company in its sole
discretion, whose determination shall be final and binding on all parties. Any
Private Notes so withdrawn will be deemed not to have been validly tendered
for purposes of the Exchange Offer and no Exchange Notes will be issued with
respect thereto unless the Private Notes so withdrawn are validly retendered.
Properly withdrawn Private Notes may be retendered by following one of the
procedures described above under "The Exchange Offer--Procedures for
Tendering" at any time prior to the Expiration Date.
 
CONDITIONS
 
  Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or exchange the Exchange Notes for, any
Private Notes, and may terminate the Exchange Offer as provided herein before
the acceptance of such Private Notes, if the Exchange Offer violates
applicable law, rules or regulations or an applicable interpretation of the
staff of the Commission.
 
  If the Company determines in its sole discretion that any of these
conditions are not satisfied, the Company may (i) refuse to accept any Private
Notes and return all tendered Private Notes to the tendering holders, (ii)
extend the Exchange Offer and retain all Private Notes tendered prior to the
expiration of the Exchange Offer, subject, however, to the rights of holders
to withdraw such Private Notes (see "--Withdrawal of Tenders") or (iii) waive
such unsatisfied conditions with respect to the
 
                                      30
<PAGE>
 
Exchange Offer and accept all properly tendered Private Notes that have not
been withdrawn. If such waiver 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 Private
Notes, and the Company will extend the Exchange Offer for a period of five to
ten business days, depending upon the significance of the waiver and the
manner of disclosure to the registered holders, if the Exchange Offer would
otherwise expire during such five to ten business day period.
 
TERMINATION OF CERTAIN RIGHTS
 
  All rights under the Registration Rights Agreement (including registration
rights) of holders of the Private Notes eligible to participate in the
Exchange Offer will terminate upon consummation of the Exchange Offer except
with respect to the Company's continuing obligations (i) to indemnify such
holders (including any broker-dealers) and certain parties related to such
holders against certain liabilities (including liabilities under the
Securities Act), (ii) to provide, upon the request of any holder of a
transfer-restricted Private Note, the information required by Rule 144A(d)(4)
under the Securities Act in order to permit resales of such Private Notes
pursuant to Rule 144A, (iii) to use its best efforts to keep the Registration
Statement effective to the extent necessary to ensure that it is available for
resales of transfer-restricted Private Notes by broker-dealers for a period of
up to one year from the date the Registration Statement is declared effective
and (iv) to provide copies of the latest version of the Prospectus to broker-
dealers upon their request for a period of up to one year from the date the
Registration Statement is declared effective.
 
ADDITIONAL INTEREST
 
  In the event of a Registration Default (as defined in the Registration
Rights Agreement), the Company is required to pay as liquidated damages,
Additional Interest (as defined in the Registration Rights Agreement) to each
holder of Transfer Restricted Securities (as defined below), during the first
90-day period immediately following the occurrence of such Registration
Default in an amount equal to $0.05 per week per $1,000 principal amount of
Private Notes constituting Transfer Restricted Securities held by such holder.
Transfer Restricted Securities shall mean each Private Note until (i) the date
on which such Private Note has been exchanged for an Exchange Note in the
Exchange Offer and is entitled to be resold to the public by the holder
thereof without complying with the prospectus delivery requirements of the
Securities Act, (ii) the date on which such Private Note has been effectively
registered under the Securities Act and disposed of in accordance with the
Shelf Registration Statement (as defined in the Registration Rights Agreement)
and (iii) the date on which such Private Note is distributed to the public
pursuant to Rule 144(k) under the Securities Act or by a broker-dealer
pursuant to the "Plan of Distribution" set forth in this Prospectus (including
delivery of this Prospectus). The amount of the Additional Interest will
increase by an additional $0.05 per week per $1,000 principal amount of
Private Notes constituting Transfer Restricted Securities for each subsequent
90-day period until all Registration Defaults have been cured, up to a maximum
Additional Interest of $0.50 per week per $1,000 principal amount of Private
Notes constituting Transfer Restricted Securities. Following the cure of all
Registration Defaults, the payment of Additional Interest will cease. The
filing and effectiveness of the Registration Statement of which this
Prospectus is a part and the consummation of the Exchange Offer will eliminate
all rights of the holders of Private Notes eligible to participate in the
Exchange Offer to receive damages that would have been payable if such actions
had not occurred.

FEES AND EXPENSES
 
  The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone or in person by officers and regular
employees of the Company and its affiliates.
 
  The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers or others
soliciting acceptances of the Exchange Offer. The Company, however, will 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 cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company and are estimated in the aggregate to be approximately
$70,000. Such expenses include registration fees, fees and expenses of the
Exchange Agent and the Trustee, accounting and legal fees and printing costs,
among others.
 
  The Company will pay all transfer taxes, if any, applicable to the exchange
of Private Notes pursuant to the Exchange Offer. If, however, a transfer tax
is imposed for any reason other than the exchange of the Private Notes
pursuant to 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.
 
CONSEQUENCES OF NOT EXCHANGING PRIVATE NOTES
 
  Participation in the Exchange Offer is voluntary. Holders of the Private
Notes are urged to consult their financial and tax advisors in making their
own decisions on what action to take.
 
  Private Notes that are not exchanged for Exchange Notes pursuant to the
Exchange Offer will continue to be deemed restricted securities under the
Securities Act and subject to the restrictions on transfer of such Private
Notes as set forth in the legend thereon. Accordingly, the Private Notes may
not be offered or sold, unless registered under the Securities Act or sold
pursuant to an exemption from, or in a transaction not subject to, the
Securities Act and applicable state securities laws. Furthermore, any and all
registration rights under the Registration Rights Agreement held by holders of
Private Notes eligible to participate in the Exchange Offer will be
extinguished as a result of the completion of the Exchange Offer. See "Risk
Factors--Consequences of Not Exchanging Private Notes."
 
ACCOUNTING TREATMENT
 
  For accounting purposes, the Company will recognize no gain or loss as a
result of the Exchange Offer. The expenses of the Exchange Offer will be
amortized over the term of the Exchange Notes.

                                  THE MERGER
 
  On October 31, 1995, the Company announced that it had entered into an
Agreement and Plan of Merger dated as of October 30, 1995, by and among Coda,
JEDI and CAI, whereby JEDI would acquire in the Merger all outstanding shares
of common stock, par value $0.02 per share, of Coda (the "Common Stock").
Concurrently with the execution of the Merger Agreement, JEDI and CAI entered
into certain agreements with the Management Group providing for a continuing
role of management in the Company after the Merger. The per share purchase
price for the Common Stock was $7.75 in cash (for an aggregate purchase price
of approximately $176.2 million). The Merger was completed on February 16,
1996.
 
  JEDI was formed as a limited partnership between CalPERS and an affiliate of
ECT, with the ECT affiliate designated as the general partner. The purpose of
the partnership is to invest in a diversified portfolio of energy related
assets.
 
  The Management Group entered into written agreements with JEDI and CAI
concerning their employment with and/or equity participation in the Company.
The Management Group holds an aggregate of approximately 1.5% of the Company's
common stock (approximately 5% on a fully diluted basis, including options
granted to such persons). See "Executive Compensation and Other Information."
 
  The sources and uses of funds related to financing the Merger were as

                                USE OF PROCEEDS
 
  The net proceeds of the sale of the Private Notes were approximately $107.25
million and $100 million of such proceeds were used to repay all of the
principal amount of the indebtedness owed to JEDI (the "JEDI Debt") incurred
by CAI in connection with the Merger and assumed by the Company upon the
Company's merger with CAI. The JEDI Debt bore interest at the rate of U.S.
Treasury instruments with a maturity closest to the maturity date of the JEDI
Debt plus 6.25% per annum; however, during the first six months, the Company
could choose an interest rate option which provided for interest at the rate
of LIBOR plus 4.25% per annum. The JEDI Debt had a maturity date of February
16, 2003. See "The Merger" and "Certain Transactions."
 
  The remaining net proceeds of approximately $7.25 million, together with
available corporate cash of $2.75 million, were used to repay indebtedness
outstanding under the Credit Agreement (which had an outstanding balance of
approximately $122.0 million at December 31, 1995 and approximately $80.0
million at March 31, 1996). The indebtedness under the Credit Agreement was
incurred primarily in connection with acquisitions of producing properties and
for other general corporate purposes. After application of such net proceeds
of the sale of the Private Notes, approximately $35.0 million is available as
of March 31, 1996 for reborrowing under the Credit Agreement to be used for
general corporate purposes, which may include acquiring producing oil and
natural gas properties or companies owning the same. The Company has no
current understandings or agreements in respect of any pending material
acquisition. See "Description of Other Indebtedness--Credit Agreement" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

               SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA
 
  The following table sets forth for the period indicated selected historical
and pro forma financial data for the Company. The selected historical
financial data as of and for each of the years in the five-year period ended
December 31, 1995, have been derived from the historical financial statements
of the Company, which were audited by Ernst & Young LLP, independent auditors.
The selected historical financial data as of and for the periods ended March
31, 1995, February 16, 1996 and March 31, 1996 have been derived from the
unaudited consolidated financial statements of the Company included elsewhere
herein. The Company acquired significant producing oil and natural gas
properties in all the periods presented which affect the comparability of the
historical financial and operating data for the periods presented. As a result
of the Merger, JEDI acquired Coda effective February 16, 1996. The Merger has
been accounted for using the purchase method of accounting. As such, JEDI's
cost of acquiring Coda has been allocated to the assets and liabilities
acquired based on estimated fair values. As a result, the Company's financial
position and operating results subsequent to the date of the Merger reflect a
new basis of accounting and are not comparable to prior periods. The pro forma
condensed financial data presented in the table below are derived from the Pro
Forma Condensed Financial Statements included elsewhere in this Prospectus.
 
  The information below should be read in conjunction with "Management's
Discussion and Analysis of Financial Condition and Results of Operations," the
Historical Financial Statements of the Company and the notes thereto, as well
as the Pro Forma Condensed Financial Statements and the notes thereto included
elsewhere in this Prospectus.

 (1) Reflects the pro forma effect of the Snyder Acquisition, the Merger, the
     sale of the Private Notes and the application of the proceeds thereof to
     retire the JEDI Debt and pay down a portion of the outstanding borrowings
     under the Credit Agreement. See the Company's Pro Forma Condensed
     Financial Statements, included elsewhere in this Prospectus, for a
     discussion of the preparation of this data. The pro forma combined
     results of operations exclude a charge of approximately $53.3 million
     (net of related deferred taxes of $30.0 million) representing the
     adjustment of the carrying value of proved oil and gas properties
     pursuant to the full cost method of accounting. Such adjustment has been
     included in the historical results of operations of the Company in the
     period the Merger was consummated. Pro forma net cash provided by
     operating activities was obtained by adjusting the historical amount for
     the pro forma changes in oil and natural gas sales, oil and natural gas
     production expenses, general and administrative expenses and interest
     expense. The exchange of the Exchange Notes for the Private Notes would
     have no effect on the pro forma information. See also "Use of Proceeds"
     and "Capitalization."
 (2) The Company ceased its third party natural gas marketing operations in
     1992. The Company acquired Taurus in April 1994.
 (3) Total costs and expenses for the periods ended February 16, 1996 and
     March 31, 1996 include approximately $3.2 million of stock option
     compensation expense and $83.3 million for the writedown of oil and gas
     properties, respectively.
 (4) For purposes of computing the ratio of earnings to fixed charges,
     earnings consist of income before income taxes plus fixed charges. Fixed
     charges consist of interest expense. For the periods ended December 31,
     1992, February 16, 1996 and March 31, 1996, earnings were inadequate to
     cover fixed charges by approximately $1.1 million, $1.8 million and $83.1
     million, respectively. Pro forma earnings for the year ended December 31,
     1995 and three months ended March 31, 1996, would have been inadequate to
     cover fixed charges by approximately $7.1 million and $283,000,
     respectively.
 (5) In addition to cash flows provided by operating activities, the Company
     also has significant cash flows which are provided by or used in
     investing and financing activities. See "Management's Discussion and
     Analysis of Financial Condition and Results of Operations--Liquidity and
     Capital Resources," "--Effects of the Merger, the Sale of the Private
     Notes and the Exchange Offer--Credit Agreement" and the Historical
     Financial Statements of the Company.
 (6) EBITDA is calculated as operating income before interest, income taxes,
     depletion, depreciation and amortization. EBITDA is not a measure of cash
     flow as determined by generally accepted accounting principles ("GAAP").
     The Company has included information concerning EBITDA because EBITDA is
     a measure used by certain investors in determining the Company's
     historical ability to service its indebtedness. EBITDA should not be
     considered as an alternative to, or more meaningful than, net income or
     cash flows as determined in accordance with GAAP as an indicator of the
     Company's operating performance or liquidity. Debt/EBITDA is calculated
     only for the historical annual periods. EBITDA for the period ended
     February 16, 1996 is net of approximately $3.2 million of stock option
     compensation expense which is a non-cash charge.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
GENERAL
 
  The Company is an independent energy company principally engaged in the
acquisition and exploitation of producing oil and natural gas properties. The
Company also owns and operates natural gas processing and liquids extraction
facilities and natural gas gathering systems. The Company seeks to acquire
properties whose predominant economic value is attributable to proved
producing reserves and to enhance that value through control of operations,
reduction of costs, and property development.
 
  The Company's principal strategy is to increase oil and natural gas
reserves, production and cash flow by selectively acquiring and exploiting
producing oil and natural gas properties, especially those properties with
enhanced recovery and other lower risk development potential. The Company's
exploitation efforts include, where appropriate, the drilling of lower risk
development wells, the initiation of secondary recovery projects, the
renegotiation of marketing agreements and the reduction of drilling,
completion and lifting costs. Cost savings may be principally achieved through
reductions in field staff and the more effective utilization of field
facilities and equipment by virtue of geographic concentration. The success of
the Company's strategy is dependent upon a number of factors, some of which
are beyond its control. See "Risk Factors."
 
  As a result of the Company's successful acquisition and exploitation
activities, the Company has shown significant growth in reserves, production
and EBITDA over the last five years. From January 1, 1991 to December 31,
1995, the Company completed acquisitions with an aggregate purchase price of
$172.2 million and estimated reserves at the date of acquisition of 47.1 Mmboe
(treating the acquisition of Diamond for this purpose as a purchase). The
Company's producing properties are concentrated onshore in the mid-continent
region of the United States. At December 31, 1995, the Company had proved
reserves of 42.6 Mmbbls of oil and 37.1 Bcf of natural gas, aggregating 48.8
Mmboe. The Company has two principal operating sources of cash: (i) net oil
and natural gas sales from its oil and natural gas properties and (ii) net
margins earned from gas gathering and processing operations.
 
  The Company expects to continue its efforts to acquire additional oil and
natural gas properties. Future acquisitions, if any, would necessitate, in
most cases, borrowing additional funds under the Credit Agreement. The ability
to borrow such funds is dependent upon the Company's borrowing base under the
Credit Agreement.
 
  On February 16, 1996, the Company completed the Merger. The Merger has been
accounted for using the purchase method of accounting. As such, JEDI's cost of
acquiring Coda has been allocated to the assets and liabilities acquired using
estimated fair values. As a result, the Company's financial position and
operating results subsequent to the date of the Merger reflect a new basis of
accounting and are not comparable to prior periods. The immediately following
sections, "--Results of Operations" and "--Liquidity and Capital Resources,"
discuss the Company's historical financial position and operating results. For
a discussion of the expected impact of the Merger and the sale of the Private
Notes on the Company's financial position and results of operations see "--
Effects of the Merger, the Sale of the Private Notes and the Exchange Offer."

 COMPARISON OF THE THREE MONTHS ENDED MARCH 31, 1995 AND 1996
 
  The unaudited pro forma combined information was prepared as if the Merger
and the issuance of $110.0 million of Notes had occurred on January 1, 1995.
The unaudited pro forma information was prepared by combining the two 1996
periods and giving effect to adjustments affecting (i) depletion, depreciation
and amortization, (ii) interest expense, (iii) income taxes and (iv) certain
other costs resulting from the Merger as more fully outlined in the Notes to
Pro Forma Condensed Financial Statements contained elsewhere in this
Prospectus. The comparisons below compare the unaudited pro forma combined
information to historical information for 1995.
 
  Oil and natural gas sales for the three months ended March 31, 1996
increased 14% to approximately $17.0 million from approximately $14.9 million
in the comparable period in 1995 primarily due to an 8% increase in oil
production and an increase of $1.22 per barrel and $0.26 per Mcf in the
average sales price of oil and natural gas, respectively. The increase in
production is a result of the acquisition of producing oil and natural gas
properties in the fourth quarter of 1995, the Company's development drilling
program and favorable responses from certain of the Company's waterflood
units. This increase was partially offset by a 15% decrease in natural gas
production (due primarily to sales of properties). During the three months
ended March 31, 1996, 89% of oil and natural gas sales was attributable to oil
production. Oil and natural gas prices remain unpredictable. See "--Changes in
Prices and Hedging Activities" below.
 
                                      39
<PAGE>
 
  Gas gathering and processing revenues for the three months ended March 31,
1996 increased 28% to approximately $10.1 million from approximately $7.9
million in the comparable period in 1995 primarily due to a 45% and a 23%
increase in the average sales price for natural gas and natural gas liquids,
respectively. This increase was partially offset by a decrease in natural gas
liquids volumes.
 
  Gas gathering and processing expenses for the three months ended March 31,
1996 increased 26% to approximately $8.5 million from approximately $6.7
million in the comparable period in 1995 primarily due to an increase in the
purchase price paid to producers. Gas gathering and processing expenses
usually fluctuate in direct proportion to gas gathering and processing
revenues.
 
  Oil and natural gas production expenses (including production taxes) for the
three months ended March 31, 1996 increased 14% to approximately $7.5 million
from approximately $6.6 million for the same period in 1995 reflecting the
effects of production from the properties acquired during the fourth quarter
of 1995 and from new wells drilled. Oil and natural gas production expenses
for the three months ended March 31, 1996 were $7.46 per Boe and are expected
to remain near this level for the remainder of the year.
 
  Pro forma depletion, depreciation and amortization expense for the three
months ended March 31, 1996 increased 42% to approximately $6.9 million from
approximately $4.9 million for the historical period in 1995 reflecting the
increase in the carrying value of the Company's assets as a result of the
Merger and an increase in oil production from acquisitions during the fourth
quarter of 1995 and property development. Oil and natural gas depletion,
depreciation and amortization expense increased from $4.33 per Boe for the
three months ended March 31, 1995, to $5.94 per Boe on a pro forma basis for
the three months ended March 31, 1996. The Company anticipates that the
depletion, depreciation and amortization rate per Boe will be approximately
$5.94 for 1996 absent significant additional acquisitions.
 
  General and administrative expenses for the three months ended March 31,
1996 were essentially unchanged from 1995. This is primarily due to increased
overhead charges billed to working interest owners on the properties acquired
in 1995 being largely offset by additional employees needed as a result of
acquisitions of oil and natural gas properties. The Company expects base
general and administrative expenses, net of overhead recoveries, to remain
near this level, absent significant additional acquisitions.
 
  Pro forma interest expense for the three months ended March 31, 1996
increased 108% to approximately $4.3 million from approximately $2.1 million
for the historical period in 1995 primarily due to increases in outstanding
debt levels as a result of the Merger which reduced the Company's bank debt,
but added $110.0 million of subordinated debt bearing interest at 10 1/2% per
annum. Also contributing to the increase were amounts borrowed during 1995 to
fund development drilling and property acquisitions.
 
  The historical results of operations for the period ended February 16, 1996
include approximately $3.2 million of stock option compensation expense as a
result of the replacement of certain outstanding options and warrants with new
options subject to a lower exercise price.
 
  The historical results for the period ended March 31, 1996 includes a
writedown of oil and natural gas properties of approximately $83.3 million to
the full cost pool ceiling based on product prices at the date of the Merger.
The allocation of JEDI's purchase price to the assets and liabilities of Coda
resulted in a significant increase in the carrying value of the Company's oil
and gas properties. Under the full cost method of accounting, the carrying
value of oil and gas properties (net of related deferred taxes) is generally
not permitted to exceed the sum of the present value (10% discount rate) of
estimated future net cash flows (after tax) from proved reserves, based on
current prices and costs, plus the lower of cost or estimated fair value of
unproved properties (the "cost center ceiling"). Based upon the allocation of
 
                                      40
<PAGE>
 
JEDI's purchase price and estimated proved reserves and product prices in
effect at the date of the Merger, the purchase price allocated to oil and gas
properties was in excess of the cost center ceiling by approximately $83.3
million ($53.3 million net of related deferred taxes). The resulting writedown
is a non-cash charge and has been included in the results of operations for
the period ended March 31, 1996.
 
  The pro forma net loss for the three months ended March 31, 1996 was
approximately $279,000 compared to net income of approximately $1.3 million
for the historical period in 1995. This decrease resulted primarily from
increases in depletion, depreciation and amortization and interest expense as
a result of the Merger partially offset by an increase in oil production and
higher oil prices.
 
 COMPARISON OF THE YEARS ENDED DECEMBER 31, 1994 AND 1995
 
  Oil and natural gas sales for the year ended December 31, 1995 increased 20%
to approximately $61.0 million from approximately $50.7 million in 1994
primarily due to a 19% increase in oil production and an increase of $1.22 per
barrel in the average sales price for oil. The increase in production was a
result of the acquisition of producing oil and natural gas properties during
the fourth quarters of 1994 and 1995, the Company's development drilling
program and favorable responses from certain of the Company's waterflood
units. This increase was partially offset by an 11% decrease in natural gas
production (due primarily to sales of properties) and a decrease in the
average sales price for natural gas of $0.17 per Mcf. During the year ended
December 31, 1995, 89% of oil and natural gas sales was attributable to oil
production. Oil and natural gas prices remain unpredictable. See "--Changes in
Prices and Hedging Activities."
 
  As a result of the acquisition of Taurus on April 29, 1994, gas gathering
and processing revenues, expenses and gross profit increased significantly for
the year ended December 31, 1995, compared to 1994. The year ended December
31, 1994 only includes eight months of Taurus' operations. Contributing to the
increases in revenues and expenses was the acquisition in January 1995 of the
remaining ownership interest in one of Taurus' gas plants and associated
facilities for $6.5 million. The levels of revenues and expenses attributed to
Taurus' operations are largely dependent on natural gas and natural gas
liquids prices and plant throughput volumes and, therefore, may fluctuate
significantly.
 
  Oil and natural gas production expenses (including production taxes) for the
year ended December 31, 1995 increased 25% to approximately $27.1 million from
approximately $21.6 million for 1994, reflecting the effects of the increased
production from the properties acquired in 1994 and from new wells drilled.
Oil and natural gas production expenses for the year ended December 31, 1995
were $6.95 per Boe. Absent additional significant acquisitions, the Company
expects production expenses to be between $7.00 and $7.50 per Boe in 1996.
 
  Depletion, depreciation and amortization expense for the year ended December
31, 1995 increased 20% to approximately $19.7 million from approximately $16.4
million for 1994, reflecting the increase in oil production from acquisitions
in 1994, property development and the acquisition of Taurus in April 1994. The
increase attributable to Taurus was approximately $1.2 million. Oil and
natural gas depletion, depreciation and amortization expense increased to
$4.33 per Boe for the year ended December 31, 1995 from $4.27 per Boe for
1994. The increase reflects the relatively higher purchase price of the
reserves related to the properties acquired during 1994.
 
  General and administrative expenses for the year ended December 31, 1995
decreased to approximately $2.9 million from approximately $3.1 million for
1994. This decrease was primarily due to increased overhead charges billed to
working interest owners on the properties acquired during the fourth quarters
of 1994 and 1995, being partially offset by additional employees needed as a
result of acquisitions of oil and natural gas properties and the acquisition
of Taurus.
 
                                      41
<PAGE>
 
  Interest expense for the year ended December 31, 1995 increased 64% to
approximately $8.7 million from approximately $5.3 million for 1994, primarily
due to increases in outstanding debt levels used to fund development drilling,
oil and natural gas property acquisitions and the acquisition of Taurus and
related assets, and higher market interest rates in 1995.
 
  Business combination expenses of $1.8 million in 1994 were related to the
acquisition of Diamond pursuant to a merger. The merger with Diamond was
accounted for as a pooling of interests and accordingly the transaction costs
were expensed when incurred.
 
  Net income for the year ended December 31, 1995 increased to approximately
$5.8 million from approximately $3.3 million for 1994, primarily due to (i) an
increase in oil production from the Company's waterflood units, the Company's
development drilling program and the oil and natural gas property acquisitions
during the fourth quarters of 1994 and 1995, (ii) an increase in the average
sales price of oil by $1.22 per barrel and (iii) the lack of business
combination expenses in 1995.
 
 COMPARISON OF THE YEARS ENDED DECEMBER 31, 1993 AND 1994
 
  Oil and natural gas sales for the year ended December 31, 1994 increased 30%
to approximately $50.7 million from approximately $38.9 million in 1993
primarily due to an increase in oil and natural gas production of 50% and 6%,
respectively, as a result of the acquisition of producing oil and natural gas
properties in the third quarter of 1993, the Company's development drilling
program and the favorable response of Diamond's waterflood units, partially
offset by a decrease in oil prices. During the year ended December 31, 1994,
83% of oil and natural gas sales was attributable to oil production.
 
  On April 29, 1994, the Company acquired 100% of the issued and outstanding
common stock of Taurus, a privately held Texas corporation, in exchange for
1.5 million shares of the Company's Common Stock, valued at approximately $7.3
million, and approximately $3.3 million cash. The Company assumed existing
Taurus debt of approximately $9.8 million. Taurus owns and operates three gas
processing and liquids extraction facilities and approximately 700 miles of
gas gathering systems located primarily in west central Texas.
 
  As a result of this acquisition, gas gathering and processing revenues,
expenses and gross profit increased significantly for the year ended December
31, 1994, which reflects eight months of activity for Taurus. In January 1995,
Taurus purchased for $6.5 million the remaining interest in one of the plants
that it operates. The level of revenues and expenses for Taurus is largely
dependent on natural gas and natural gas liquids prices and plant throughput
volumes and, therefore, may fluctuate significantly.
 
  Other income for the year ended December 31, 1994 increased to approximately
$822,000 from approximately $441,000 for 1993, due primarily to the receipt in
1994 of $107,000 of interest income attributable to the receipt in December
1993 of previously suspended oil and natural gas sales proceeds and to the
receipt of $117,000 related to the settlement of claims which arose in
connection with an unsuccessful acquisition effort in a prior year. Also
contributing to the increase was an increase in rental income from the
Company's office building.
 
  Oil and natural gas production expenses (including production taxes) for the
year ended December 31, 1994 increased 23% to approximately $21.6 million from
approximately $17.6 million for 1993, reflecting the effects of increased
production from the properties acquired in the third quarter of 1993 and from
new wells drilled. Oil and natural gas production expenses per Boe decreased
in 1994 to $6.22 per Boe from $6.90 per Boe in 1993, reflecting the effect of
the relatively lower lifting cost related to the properties acquired in the
third quarter of 1993 and the effect of increased production response from the
Diamond waterflood units.
 
                                      42
<PAGE>
 
  Depletion, depreciation and amortization expense for the year ended December
31, 1994 increased 52% to approximately $16.4 million from approximately $10.8
million for 1993, reflecting the increases in production from the acquisitions
in the third quarter of 1993 and the acquisition of Taurus in April 1994. The
increase attributable to Taurus was approximately $1.4 million. Oil and
natural gas depletion, depreciation and amortization expense increased from
$4.15 per Boe for the year ended December 31, 1993, to $4.27 per Boe for 1994.
The increase reflects the relatively higher purchase price of the reserves
related to the properties acquired during the third quarter of 1993.
 
  General and administrative expenses for the year ended December 31, 1994
increased to approximately $3.1 million from approximately $2.6 million for
1993. This increase was primarily due to additional employees needed as a
result of the 1993 acquisitions and the acquisition of Taurus, partially
offset by increased overhead charges billed to working interest owners on the
properties acquired during 1993. The increase attributable to Taurus was
approximately $483,000.
 
  Interest expense for the year ended December 31, 1994 increased 10% to
approximately $5.3 million from approximately $4.8 million for 1993, primarily
as a result of increases in outstanding debt levels used to fund development
drilling, property acquisitions and the acquisition of Taurus, partially
offset by lower market interest rates in the first half of 1994.
 
  In connection with the merger with Diamond, the Company incurred
approximately $1.8 million of legal, accounting, printing and other costs
related to the combination of the previously separate entities. Included in
these expenses is the writeoff of approximately $316,000 of Diamond's deferred
financing costs. Under pooling of interests accounting, these costs were
expensed in September 1994. Furthermore, certain of these expenses are neither
deductible nor amortizable for income tax purposes, resulting in a higher than
expected effective tax rate.
 
  Net income for the year ended December 31, 1994 increased to approximately
$3.3 million from approximately $2.3 million for 1993, primarily due to an
increase in oil and natural gas production from Diamond's waterflood units,
the Company's development drilling program and the acquisitions in the third
quarter of 1993, partially offset by a $1.02 per barrel decrease in average
oil prices and $1.8 million in business combination expenses.
 
 CHANGES IN PRICES AND HEDGING ACTIVITIES
 
  Annual average oil and natural gas prices have fluctuated significantly over
the past three years. The Company's weighted average oil price per Bbl during
1995 and at December 31, 1995 was $17.08 and $18.31, respectively. For the
three months ended March 31, 1996, the Company averaged $1.33 per barrel less
(including an oil hedging price decrease of $0.32 per barrel) and $0.65 per
Mcf less for its oil and natural gas sales, respectively, than the average
NYMEX prices for the same period. For the year ended December 31, 1995, the
Company averaged $1.32 per Bbl less (including an oil hedging price increase
of $0.09 per barrel) and $0.13 per Mcf less for its oil and natural gas sales,
respectively, than the average NYMEX prices for the same period. The Company's
weighted average price per Bbl during 1994 and at December 31, 1994, was
$15.86 and $16.24, respectively. For the year ended December 31, 1994, the
Company averaged $1.33 per Bbl and $0.20 per Mcf, respectively, less for its
oil and natural gas sales than the average NYMEX prices for the same period.
 
  Pursuant to the loan agreements with Diamond's former primary lender,
Diamond entered into an agreement with a refining and marketing company to
sell a fixed number of barrels attributable to its share of production of
liquid hydrocarbons from certain formerly secured properties at a price of
$15.25 per barrel. The effect of this contract was to lower the Company's 1995
and first quarter of 1996 oil revenue by approximately $1.0 million ($0.32 per
barrel) and $123,000 ($0.15 per barrel), respectively. The remaining
commitment under this agreement at December 31, 1995, was 47,000 barrels. The
Company fulfilled this commitment during the first quarter of 1996.

  In an effort to reduce the effects of the volatility of the price of oil and
natural gas on the Company's operations, management has adopted a policy of
hedging oil and natural gas prices through the use of commodity futures,
options, and swap agreements whenever market prices are in excess of the
prices anticipated in the Company's operating budget and profit plan. While
the use of these hedging arrangements limits the downside risk of adverse
price movements, it may also limit future gains from favorable movements. All
hedging is accomplished pursuant to exchange-traded contracts or master swap
agreements based upon standard forms. The Company addresses market risk by
selecting instruments whose value fluctuations correlate strongly with the
underlying commodity being hedged. Credit risk related to hedging activities,
which is minimal, is managed by requiring minimum credit standards for
counterparties, periodic settlements and mark-to-market valuations. The
Company has not historically been required to provide any significant amount
of collateral in connection with its hedging activities. The following table
sets forth the barrels and weighted average NYMEX prices hedged under various
swap agreements entered into as of March 31, 1996.

</TABLE>
 
  As of March 31, 1996, the Company had open positions for sold call options
covering 25,000 Bbls of oil per month at an option price of $18.30 per Bbl for
the period April 1996 to August 1996, increasing to $20.00 per Bbl for the
period from September 1996 to August 1997. Under the standard form swap
agreements in use by the Company, the Company has a potential liability when
the NYMEX price exceeds the swap price. The total potential liability is equal
to the difference between the swap price and the NYMEX price for the
production month hedged multiplied by the number of barrels swapped. To the
extent this total liability exceeds the credit limit established by the
counterparty, the Company may be required to utilize cash to fund a margin
account. The Company has not historically had to fund a margin account.
 
  During the years ended December 31, 1993 and 1994, the Company's oil and
natural gas sales were reduced by $289,000 and $5,000, respectively as a
result of hedging transactions. During the year ended December 31, 1995, the
Company's oil sales were increased by $298,000, representing an average price
increase of $0.09 per barrel of oil, as a result of hedging transactions.
During the periods ended February 16, 1996 and March 31, 1996, the Company's
oil revenues were decreased by $14,000 and $250,000, respectively, as a result
of hedging transactions. See Note 7 of the Notes to the Company's Historical
Financial Statements for a further discussion of the Company's hedging
activities.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  At March 31, 1996, the Company had cash and cash equivalents aggregating
approximately $3.5 million and working capital of approximately $9.4 million.
Cash provided by operating activities for the three months ended March 31,
1996 decreased to approximately $4.6 million compared to $5.1 million for the
comparable period in 1995 due primarily to an increase in interest expense
partially offset by an increase in oil production and an oil price increase.
Excluding the impact of the Merger, cash flows used in investing activities
decreased from $11.6 million for the three months ended March 31, 1995 to $2.2
million for the comparable period in 1996, as a result of a higher level of
additions to property and equipment in 1995. Investing activities in 1996 also
include the impact of the purchase of Coda by JEDI. Cash flows provided by
financing activities increased to $176.6 million for the three months ended
March 31, 1996 from $3.1 million for the comparable period in 1995, primarily
due to financing transactions related to the Merger. See "Effects of the
Merger, the Sale of the Private Notes and the Exchange Offer--The Merger"
below.
 
                                      44
<PAGE>
 
  At December 31, 1995, the Company had cash and cash equivalents aggregating
approximately $4.6 million and working capital of approximately $8.3 million.
Cash provided by operating activities for the year ended December 31, 1995
increased to approximately $24.3 million compared to $23.0 million for 1994,
due primarily to an increase in oil production and an oil price increase. Cash
flows used in investing activities decreased from $56.8 million for the year
ended December 31, 1994 to $43.0 million in 1995. This decrease was a result
of the sale of assets in 1995 for almost $5.7 million and a slight decrease in
the total spending on oil and natural gas properties in 1995, partially offset
by the acquisition by Taurus of an additional interest in one of its plants
for $6.5 million. Cash flows provided by financing activities decreased to
$16.9 million for the year ended December 31, 1995 from $36.2 million for
1994, primarily due to a decrease in net borrowings under the Company's then-
existing credit agreement. As a result of the Merger, the Company's financial
position and results of operations reflect a new basis of accounting and are
not comparable to prior periods. The following section discusses the expected
impact of the Merger, the sale of the Private Notes and the Exchange Offer on
the Company's financial position and results of operations.
 
EFFECTS OF THE MERGER, THE SALE OF THE PRIVATE NOTES AND THE EXCHANGE OFFER
 
 THE MERGER
 
  On February 16, 1996, the Company completed the Merger. The Merger has been
accounted for using the purchase method of accounting. As such, JEDI's cost of
acquiring Coda has been allocated to the assets and liabilities acquired using
estimated fair values. As a result, the Company's financial position and
operating results subsequent to the date of the Merger reflect a new basis of
accounting and are not comparable to prior periods. Concurrently with the
execution of the Merger Agreement, JEDI and CAI entered into certain
agreements with the Management Group providing for a continuing role of
management in the Company after the Merger. The sources and uses of funds
related to financing the Merger were as follows:

  The Company incurred substantial indebtedness in connection with the Merger
and is highly leveraged. As of March 31, 1996, the Company had total
indebtedness of approximately $191.8 million and stockholders' equity
(including Preferred Stock) of approximately $60.5 million. After giving pro
forma effect to the Merger and the related financing transactions, including
the sale of the Private
 
                                      45
<PAGE>
 
Notes and the Exchange Offer, and the Snyder Acquisition, the Company's
earnings would have been insufficient to cover its fixed charges by
approximately $7.1 million for 1995. Pro forma interest expense for 1995 would
have been approximately $18.6 million. Pro forma cash flow from operations
(assuming that the additional interest was paid in cash) would have been
approximately $17.1 million. Based upon the Company's current level of
operations and anticipated growth, management of the Company believes that
available cash, together with available borrowings under the Credit Agreement,
will be adequate to meet the Company's budgeted requirements for capital
expenditures and scheduled payments of principal of, and interest on, its
indebtedness, including the Notes. There can be no assurance that such
anticipated growth will be realized, that the Company's business will generate
sufficient cash flow from operations or that future borrowings will be
available in an amount sufficient to enable the Company to service its
indebtedness, including the Notes, or make necessary capital expenditures. In
addition, the Company anticipates that it is likely to find it necessary to
refinance a portion of the principal amount of the Notes at or prior to their
maturity. However, there can be no assurance that the Company will be able to
obtain financing to complete a refinancing of the Notes. See "Risk Factors--
Leverage."
 
  The Company has planned development and exploitation activities for all of
its major operating areas. The Company has budgeted capital spending of
approximately $18 million in 1996, but is not contractually committed to
expend these funds. During the first three months of 1996, the Company
incurred approximately $1.9 million of these costs. In addition, the Company
is continuing to evaluate oil and natural gas properties for future
acquisitions. Historically, the Company has used the public equity market (i)
to raise cash to fund acquisitions or repay indebtedness incurred for
acquisitions and (ii) as a medium of exchange for other companies' capital
stock or assets in connection with acquisitions. As a result of being 95%
owned by JEDI (on a fully diluted basis), the Company does not expect to
utilize the public equity market to finance acquisitions in the near term.
Accordingly, any material expenditures in connection with acquisitions would
require borrowing under the Credit Agreement or from other sources. There can
be no assurance that such funds will be available to the Company. Furthermore,
the Company's ability to borrow in the future is subject to restrictions
imposed by the Credit Agreement and the Indenture as more fully described
below. See "Description of Other Indebtedness" and "Description of Exchange
Notes--Certain Covenants--Incurrence of Indebtedness and Issuance of Preferred
Stock."
 
 CREDIT AGREEMENT
 
  In connection with the Merger, the Company entered into the Credit Agreement
to replace a prior credit facility. The borrowing base under the Credit
Agreement currently is $115.0 million. As of March 31, 1996, approximately
$35.0 million was available for borrowing under the Credit Agreement. The
borrowing base is scheduled to be redetermined on July 1, 1996; however, the
Credit Agreement allows the lenders to redetermine the borrowing base upon the
occurrence of either of the following events: (i) the sale of all, or
substantially all, of the assets or common stock of Taurus or (ii) the
issuance of public subordinated debt in an amount greater than $100.0 million.
The lenders under the Credit Agreement have agreed to waive their right to
redetermine the borrowing base with respect to the issuance of the Notes. As a
result of the sale of the Private Notes, ECT Securities Corp., an affiliate of
ECT, refunded to the Company $2.0 million in fees paid by the Company to ECT
Securities Corp. for arranging the JEDI Debt. These additional funds, together
with other available cash of $550,000 and the remaining net proceeds of the
sale of the Private Notes were used to repay approximately $10.0 million of
the indebtedness outstanding under the Credit Agreement.
 
  The Credit Agreement is unsecured. The Company has provided the bank lenders
with first lien deeds of trust on its oil and natural gas assets that will not
become effective, and that the lenders have agreed to not file, unless: (i)
80% of any outstanding borrowings in excess of the borrowing limit are not
repaid within a 90 day period, (ii) cash collateral securing a hedging
transaction exceeds 20% of
 
                                      46
<PAGE>
 
the borrowing limit or (iii) an event of default or a material adverse event,
as defined in the Credit Agreement, occurs.
 
  The Credit Agreement contains various restrictive covenants, including
limitations on the granting of liens, restrictions on the issuance of
additional debt, restrictions on investments, a requirement to maintain
positive working capital, and restrictions on dividends and stock repurchases.
The Credit Agreement also contains requirements that JEDI, Enron, CalPERS or
any wholly owned subsidiary of either Enron or CalPERS must continue to own a
majority of the outstanding equity of the Company and must have the ability to
elect the majority of the Board of Directors and that certain members of
management maintain specified levels of equity ownership in the Company and
continue their employment with the Company.
 
  So long as no default (as defined in the Credit Agreement) is continuing,
the Company has the option of having all or any portion of the amount borrowed
under the Credit Agreement be the subject of one of the following interest
rates: (i) NationsBank's prime rate, (ii) the CD Rate plus 1 1/4% to 1 5/8%
based upon the ratio of outstanding debt to the available borrowing base and
(iii) LIBOR plus 1 1/4% to 1 5/8% based upon the ratio of outstanding debt to
the available borrowing base. The Company must also pay a commitment fee of
between 0.375% to 0.425% on the unused portion of the borrowing base facility.
 
 JEDI DEBT
 
  The principal amount of JEDI Debt outstanding after the Merger was $100.0
million. A portion of the net proceeds of the sale of the Private Notes was
used to repay the JEDI Debt. The Company also paid approximately $823,000 of
accrued interest thereon. See "Use of Proceeds."
 
 10 1/2% SENIOR SUBORDINATED NOTES
 
  On March 18, 1996, the Company completed the sale of $110 million principal
amount of Notes. The proceeds of the Notes were used to fully repay the JEDI
Debt assumed in the Merger and to partially repay bank debt. The Notes bear
interest at an annual rate of 10 1/2% payable semiannually in arrears on April
1 and October 1 of each year. The Notes are general, unsecured obligations of
the Company, are subordinated in right of payment to all Senior Debt (as
defined in the Indenture governing the Notes) of Coda, and are senior in right
of payment to all future subordinated debt of the Company. The claims of the
holders of the Notes will be subordinated to Senior Debt, which, as of March
31, 1996, was $81.8 million.
 
  Coda's payment obligations under the Notes are fully, unconditionally and
jointly and severally guaranteed on a senior subordinated basis by all of
Coda's current subsidiaries and future Restricted Subsidiaries (as defined in
the Indenture). Such guarantees are subordinated to the guarantees of Senior
Debt issued by the Guarantors under the Credit Agreement and to other
guarantees of Senior Debt issued in the future.
 
  The Notes were issued pursuant to an Indenture, which contains certain
covenants that, among other things, limit the ability of Coda and its
Restricted Subsidiaries to incur additional indebtedness and issue
Disqualified Stock (as defined in the Indenture), pay dividends, make
distributions, make investments, make certain other restricted payments, enter
into certain transactions with affiliates, dispose of certain assets, incur
liens securing pari passu or subordinated indebtedness of Coda and engage in
mergers and consolidations.
 
  The Notes are not redeemable at Coda's option prior to April 1, 2001. After
April 1, 2001, the Notes will be subject to redemption at the option of Coda,
in whole or in part, at the redemption prices set forth in the Indenture, plus
accrued and unpaid interest thereon to the applicable redemption date.
 
                                      47
<PAGE>
 
  In addition, until March 12, 1999, up to $27.5 million in aggregate
principal amount of Notes is redeemable, at the option of Coda on any one or
more occasions from the net proceeds of an offering of common equity of Coda,
at a price of 110.5% of the aggregate principal amount of the Notes, together
with accrued and unpaid interest thereon to the date of the redemption;
provided, however, that at least $82.5 million in aggregate principal amount
of Notes must remain outstanding immediately after the occurrence of such
redemption; provided, further, that any such redemption shall occur within 75
days of the date of the closing of such offering of common equity.
 
  In the event of a Change of Control (as defined in the Indenture), holders
of the Notes will have the right to require Coda to repurchase their Notes, in
whole or in part, at a price in cash equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest thereon to the date of
repurchase. The Indenture requires that, prior to such a repurchase but in any
event within 90 days of such Change of Control, Coda must either repay all
Senior Debt or obtain any required consent to such repurchase of Notes.
 
 OTHER LONG-TERM DEBT
 
  The Company's 12% Senior Subordinated Debentures due 2000 (the "Debentures")
bear interest at 12% per annum, payable semiannually. At March 31, 1996,
approximately $1.2 million in aggregate principal amount of the Debentures was
outstanding. On March 28, 1996, the Company gave notice of redemption, prior
to maturity, to each of the record holders of the outstanding Debentures. The
outstanding Debentures were redeemed on May 1, 1996 at a redemption price of
100.0% of the principal amount of the Debentures plus accrued and unpaid
interest thereon. On May 1, 1996, the Company deposited with the trustee of
the Debentures funds sufficient to so redeem the Debentures, and thereafter
interest on the Debentures ceased to accrue.
 
 15% CUMULATIVE PREFERRED STOCK
 
  The Company's Certificate of Incorporation authorizes the issuance of up to
40,000 shares of Preferred Stock. In conjunction with the Merger, the Company
issued 20,000 shares of Preferred Stock to JEDI for $20.0 million in cash.
Additional shares of Preferred Stock in excess of 20,000 shares may be issued
only for the purpose of paying dividends on the issued and outstanding
Preferred Stock. The holders of each share of Preferred Stock are entitled to
receive, when and as declared by the Board of Directors, cumulative
preferential dividends at the rate of $150.00 per share per annum, payable in
equal semi-annual installments. Dividend payments will be made in cash or
through the issuance of additional shares of Preferred Stock. The payment of
Preferred Stock dividends in cash is restricted by the Credit Agreement and
the Indenture.
 
  The Company's Certificate of Incorporation requires that the Company redeem
all the issued and outstanding shares of Preferred Stock at a redemption price
of $1,000 per share, plus all accrued and unpaid dividends (including
undeclared dividends) to the date of redemption, if the Company has sufficient
funds legally available for such redemption and if such redemption would not
violate or conflict with any loan agreement, credit agreement, note agreement,
indenture or other agreement relating to indebtedness to which the Company is
a party, on or before the fifth business day after the earliest to occur of
the following: (i) the closing of the sale by the Company of Taurus and (ii) a
Trigger Event, as such term is defined in the Stockholders Agreement. The
Preferred Stock may be redeemed by the Company at its option, as a whole or in
part, to the extent the Company shall have funds legally available for such
redemption, at any time or from time to time at a redemption price of $1,000
per share, plus all accrued and unpaid dividends (including undeclared
dividends) to the date of redemption. Such redemption, whether required or
optional, is restricted by the Credit Agreement and the Indenture.

<PAGE>
 
 ENRON
 
  Enron is the parent of ECT and accordingly may be deemed to control
indirectly both JEDI and the Company. Enron and certain of its subsidiaries
and other affiliates collectively participate in nearly all phases of the oil
and natural gas industry and are, therefore, competitors of the Company. In
addition, ECT and JEDI have provided, and may in the future provide, and ECT
Securities Corp. has assisted, and may in the future assist, in arranging
financing to non-affiliated participants in the oil and natural gas industry
who are or may become competitors of the Company. Because of these various
conflicting interests, ECT, the Company, JEDI and the Management Group have
entered into the Business Opportunity Agreement which is intended to make it
clear that Enron and its affiliates have no duty to make business
opportunities available to the Company in most circumstances. The Business
Opportunity Agreement also provides that ECT and its affiliates may pursue
certain business opportunities to the exclusion of the Company. The Business
Opportunity Agreement may limit the business opportunities available to the
Company. In addition, pursuant to the Business Opportunity Agreement there may
be circumstances in which the Company will offer business opportunities to
certain affiliates of Enron. If an Enron affiliate is offered such an
opportunity and decides to pursue it, the Company may be unable to pursue it.
 
 RESULTS OF OPERATIONS
 
  As a result of the Merger, the Company has significantly more debt
outstanding at a higher weighted average interest rate than before the Merger.
On a pro forma basis reflecting the effects of the Snyder Acquisition, the
Merger and the sale of the Private Notes, as if such transactions had occurred
on January 1, 1995, pro forma depletion, depreciation and amortization
increased by $8.8 million, pro forma interest expense increased by $9.9
million and pro forma general and administrative expenses decreased by
$921,000, compared to the actual amounts reported for 1995. Pro forma EBITDA
would have increased to $40.0 million from $37.3 million on a historical
basis. Pro forma net loss for 1995 would have been $4.5 million compared to
historical net income of $5.8 million. The pro forma combined results of
operations exclude a charge of approximately $53.3 million (net of related
deferred taxes of $30.0 million) representing the adjustment of the carrying
value of proved oil and gas properties pursuant to the full cost method of
accounting. Such adjustment has been included in the results of operations of
the Company in the period the Merger was consummated.
 
  Based on the allocation of purchase price, the Company expects oil and
natural gas property depletion, depreciation and amortization to be
approximately $5.94 per Bbl in 1996. Absent significant changes in the
Company's operations or interest rates, general and administrative expenses
are expected to be approximately $3 million in 1996 and interest expense for
1996 should be approximately $17 million. Absent significant increases in
prices or increases in production through development or acquisition
activities, the Company will continue to incur net losses. In addition, the
Company will be incurring a 15% cumulative dividend on $20.0 million of
Preferred Stock (payable in cash or shares of Preferred Stock) issued to JEDI
in connection with the Merger. See Pro Forma Condensed Financial Statements
included elsewhere in this Prospectus.
 
  The Company estimates that it has approximately $15.4 million in available
net operating loss carryforwards ("NOLs"). While the Merger will result in a
change in control pursuant to (S)382 of the Internal Revenue Code, the Company
does not expect such change to have any significant impact on its ability to
utilize its NOLs.

                                   BUSINESS
 
GENERAL
 
  The Company is an independent energy company that is principally engaged in
the acquisition and exploitation of oil and natural gas properties. The
Company also owns and operates natural gas processing and liquids extraction
facilities and natural gas gathering systems. The Company seeks to acquire oil
and natural gas properties whose predominant economic value is attributable to
proved producing reserves and to enhance that value through control of
operations, reduction of costs and property development. The Company's
producing properties are concentrated in the mid-continent region of the
United States. At December 31, 1995, the Company had proved reserves of 42.6
Mmbbls of oil and 37.1 Bcf of natural gas, aggregating 48.8 Mmboe. Company
operated properties accounted for approximately 94% of its 1995 production of
3.9 Mmboe.
 
  As a result of the Company's successful acquisition and exploitation
activities, the Company has shown significant growth in reserves, production
and EBITDA over the last five years. From 1991 through 1995, the Company
achieved an average annual reserve replacement of 480% at an average cost of
$3.67 per Boe (with the acquisition of Diamond treated as a purchase instead
of a pooling). To achieve these results, management estimates that the Company
evaluated, over the last five years, in excess of 1,400 acquisition
opportunities with an aggregate market value estimated by management to exceed
$15 billion. Over the same period (with the acquisition of Diamond treated as
a purchase instead of a pooling), management estimates that the Company made
approximately 280 offers totaling more than $3 billion and successfully closed
in excess of 50 transactions having an aggregate purchase price of $172.2
million. This strategy enabled the Company to increase average net daily
production from 3,329 Boe in 1991 to 10,688 Boe in 1995, representing a
compound annual growth rate of 34%. Similarly, EBITDA increased at a 46%
compound annual growth rate from $8.2 million in 1991 to $37.3 million in
1995.
 
STRATEGY
 
  The Company's strategy is to increase oil and natural gas reserves,
production and cash flow by selectively acquiring and exploiting oil and
natural gas properties, especially those properties with enhanced recovery and
other lower risk development potential. In order to implement its strategy,
the Company principally seeks to acquire oil and natural gas properties with
the following characteristics:
 
  .  Geographic Focus--The Company has focused its acquisition activities in
     the mid-continent region of the United States. This region includes oil
     and natural gas basins with geological and production characteristics
     potentially responsive to the Company's exploitation and development
     techniques. Management believes that it has considerable experience in,
     and knowledge of, this region. The Company presently has four core
     operating areas: west Texas, north Texas, west central Oklahoma and
     southwestern Kansas. The geographic proximity of the Company's various
     properties allows the Company to minimize the number of operations and
     field production offices that it must maintain and the number of
     supervisory personnel that it must employ.
 
  .  Proved Developed Reserves--The Company prefers to acquire properties
     where the majority of the reserves are proved developed reserves
     producing from relatively shallow horizons. Management believes these
     properties generally present lower geologic and mechanical risks for
     drilling, recompleting and operating activities. Substantially all of
     the Company's wells are under 10,000 feet deep.
 
  .  Operated, High Working Interest Properties--The Company prefers to
     operate the properties it acquires and to own the majority working
     interest in those properties. This allows the Company greater control
     over (i) timing and plans for future development, (ii) drilling,
     completing and lifting costs and (iii) marketing of production. At
     December 31, 1995, the
 
                                      50
<PAGE>
 
     Company operated approximately 2,052 of the 2,190 gross producing and
     active water injection wells in which it owned an interest, and its
     weighted average working interest in its properties was approximately
     82%.
 
  .  Exploitation Potential--The Company seeks to increase production and
     recoverable reserves through exploitation efforts on the properties it
     acquires. Exploitation efforts include workovers and/or recompletions of
     existing wells; the initiation of, or improvements to, secondary
     recovery projects, particularly the use of waterflooding; and the
     drilling of lower risk development and/or infill wells. The Company
     believes that it has been able to enhance the value and to extend the
     economic life of many of the properties that it has acquired by
     utilizing techniques such as these.
 
  .  Cost Reduction Potential--The Company seeks to acquire properties where
     significant economic value can be created by lowering operating costs.
     The Company believes that it has been able to lower the lifting costs on
     certain properties it has acquired in comparison to the costs incurred
     by the major oil companies and larger independents that previously
     operated the properties. These savings were achieved through reductions
     in labor, electricity, materials and other costs.
 
  .  Price Improvement Potential--Whenever possible, the Company attempts to
     negotiate more favorable marketing agreements than those in place under
     prior owners. After the Company has begun its exploitation activities on
     its properties, it may attempt to negotiate more favorable prices as the
     volumes of oil increase. Certain of the Company's oil purchasers have
     paid and are currently paying a premium over posted prices and have
     eliminated certain quality and marketing deductions for a portion of the
     Company's oil production due to the Company's control over a significant
     volume of oil production in its core geographic areas.
 
  The Company believes that future acquisitions, like its past acquisitions,
will come from several categories of sellers including : (i) major oil
companies; (ii) companies that are consolidating operations to achieve cost
savings; (iii) companies and individuals owning interests in wells in which
the Company owns a substantial working interest; and (iv) companies with
limited capital resources.
 
  The success of the Company's strategy depends upon a number of factors
outside of the Company's control, including the availability of attractive
acquisition opportunities. In recent years, major oil companies have been
divesting many of their higher cost domestic oil and natural gas properties.
In addition, the oil and natural gas industry continues to consolidate as
smaller independents exit the business. The Company believes these trends will
continue. By increasing production and lowering operating costs, the Company
believes that it can increase economic value and cash flow as well as extend
the productive lives of these properties. See "--Exploitation and Development
Activities" and "Risk Factors--Acquisition Risks; Depletion of Reserves."
 
ACQUISITION AND EXPLOITATION OF PRINCIPAL PROPERTIES
 
 GENERAL
 
  Management estimates that the Company evaluated, over the last five years,
in excess of 1,400 acquisition opportunities with an aggregate market value
estimated by management to exceed $15 billion. Over the same period (with the
acquisition of Diamond treated as a purchase instead of a pooling), management
estimates that the Company made approximately 280 offers totaling more than $3
billion and successfully closed in excess of 50 transactions having an
aggregate purchase price of $172.2 million. Management estimates that in 1995,
the Company evaluated more than $4.5 billion of acquisition opportunities,
offered to purchase more than $1.2 billion of such opportunities and closed
transactions worth $25.4 million. The Company generally prefers to focus on
larger acquisitions. It is management's opinion that operating larger
properties will allow even greater cost savings due to economies of scale, as
well as higher prices for oil and natural gas due to the concentration of
production in a given geographic area.

 HISTORICAL ACQUISITIONS
 
  Since 1991, the Company has been actively engaged in the acquisition of
producing oil and natural gas properties located primarily in north Texas, the
Permian Basin in west Texas, west central Oklahoma and southwestern Kansas.
These acquisitions have permitted the Company to develop concentrated
ownership positions in certain producing fields, building on the Company's
knowledge of the reservoir characteristics in these areas and enhancing the
Company's ability to operate these properties more efficiently than prior
owners.
 
  1991 Acquisitions. During 1991, the Company consummated three major
purchases in north Texas and the Permian Basin in west Texas, which
established those areas as core operating areas for the Company. In March
1991, the Company paid approximately $2.9 million to acquire an existing
waterflood project located in the Wichita County Regular Field of the West
Burkburnett Area of north Texas. In May 1991, the Company paid approximately
$2.7 million to acquire 16 producing wells in the McElroy Field located in
Upton County in west Texas. The Company subsequently initiated a waterflood
project on this lease. In July 1991, the Company paid $10.5 million to acquire
an existing waterflood project and a natural gas processing plant and
gathering facility located in Wichita and Wilberger Counties in north Texas
(the "Electra Properties").
 
  1992 Acquisitions. The December 1992 purchase of producing oil and natural
gas properties located in the Permian Basin in west Texas and in north Texas
furthered the Company's objective of acquiring proved reserves in concentrated
geographic locations in which the Company was familiar with the geology and
other reservoir characteristics. These properties already were operating on
waterflood recovery. In the first of these acquisitions, the Company paid an
aggregate of approximately $17.2 million to acquire interests in 13 producing
oil and natural gas properties located in the Permian Basin of west Texas and
Lea County, New Mexico. One of these properties, the Shafter Lake Unit, is a
12,720 acre San Andres formation waterflood project. In the second
acquisition, the Company paid approximately $4.1 million to acquire working
interests in an existing waterflood project plus ancillary assets located in
Wichita, Wilberger and Hardeman Counties in north Texas. These properties are
adjacent to the Company's Electra Properties, which were acquired in 1991.
 
  1993 Acquisitions. In 1993, the Company concluded two significant
acquisitions. The first acquisition created the Company's core operating area
in southwestern Kansas. These properties were acquired from Mobil Oil
Corporation for approximately $15.8 million. The second acquisition, MJM
 
                                      52
<PAGE>
 
Oil & Gas, Inc. ("MJM"), added properties in the Company's core operating
areas of north Texas, the Permian Basin of west Texas and west central
Oklahoma.
 
  1994 Acquisitions. The most significant acquisition of oil and natural gas
properties during 1994 was the Company's acquisition of Diamond, whose
properties are principally concentrated in west central Oklahoma.
Substantially all of Diamond's properties are waterflood recovery projects
which were initiated and developed by Diamond. This acquisition also brought
to the Company additional management with experience in waterflood recovery
projects. The Company also completed two acquisitions of properties located in
west Texas in December 1994, as well as several other smaller acquisitions.
The Company paid an aggregate of $73.1 million in connection with its
acquisitions during 1994 (including $21.4 million of the Company's Common
Stock issued in connection with the Diamond merger).
 
  1995 Acquisitions. On October 6, 1995, the Company acquired 63 producing oil
and natural gas properties and related assets from Snyder. The majority of
these properties are located in the Permian Basin in west Texas. The total
purchase price of these properties was $17.1 million in cash, of which $16.0
million was financed with borrowings under the Company's then-existing credit
agreement. The Company believes that these properties present exploitation
opportunities, including opportunities to implement cost-cutting strategies
and initiate or improve secondary recovery operations and lower risk
development drilling activities. The Snyder Acquisition complements the
Company's core operating areas within the mid-continent region of the United
States. In addition to the Snyder Acquisition, the Company completed several
other smaller acquisitions during 1995. The aggregate purchase price of the
Company's acquisitions during 1995 was $25.4 million.
 
  The Company does not have a specific acquisition budget since the timing and
size of acquisitions are difficult to forecast. The Company is constantly
reviewing acquisition possibilities and anticipates acquisitions in 1996 and
thereafter. The Company may expand its geographic core areas if it identifies
properties that complement its current activities and that it believes will
likely be responsive to the Company's exploitation strategy. At the present
time, the Company has no binding agreements with respect to any significant
acquisitions.
 
EXPLOITATION AND DEVELOPMENT ACTIVITIES
 
 GENERAL
 
  The Company concentrates on exploiting proved producing properties,
including those with development potential, through workovers, behind the pipe
recompletions, secondary recovery operations, the drilling of development
wells or infill wells and other exploitation techniques. The Company has
conducted or intends to conduct significant secondary recovery/infill drilling
programs on many of the properties it has acquired.
 
  Secondary recovery projects have represented the Company's primary
development focus over the past four years. Generally, "secondary recovery"
refers to methods of oil extraction in which fluid or gas (usually water,
natural gas or CO/2/) is injected into a formation through input (injector)
wells, and oil is removed from surrounding wells. "Waterflooding" is one
proven method of secondary recovery in which water is injected into an oil
reservoir for the purpose of forcing the oil out of the reservoir rock and
into the bore of a producing well. Waterflood projects are engineered to suit
the type of reservoir, depth and condition of the field. The Company has
considerable experience with and actively employs waterflood techniques in
many of its fields in order to stimulate production.
 
  The Company also seeks to exploit its properties through cost reduction
measures, including the reduction of labor, electrical and materials costs. It
seeks to take advantage of volume discounts in the purchase of equipment and
supplies and more effectively utilize field facilities and equipment by virtue
 
                                      53
<PAGE>
 
of its geographical concentration. The Company attempts to negotiate more
favorable marketing agreements upon completion of an acquisition, particularly
for oil production. Certain oil purchasers have paid in the past and are
currently paying a premium over posted prices and have eliminated certain
quality and marketing deductions for a portion of the Company's oil production
due to the Company's control over a significant volume of oil production in
its core geographic areas.
 
  The Company makes only limited investments in exploratory drilling.
 
 EXPLOITATION RESULTS
 
  The properties presented in this table represent the ten largest properties
in which the Company had an ownership position as of January 1, 1995, based
upon the present value of estimated future net revenues at December 31, 1995.
These ten properties represent 65% of the present value of estimated future
net revenues at December 31, 1995, as estimated by the Company's independent
engineers, and are among the Company's most successful projects to date. The
present value of estimated future net revenues at December 31, 1995 and the
financial data presented provide an indication of the results of the Company's
exploitation strategy to date; however, certain of the properties acquired by
the Company have not been as successful as those described below and there can
be no assurance that the results presented below will be indicative of the
Company's future exploitation activities. The present value of future net
revenues shown below has been computed on the same basis as the Standardized
Measure, but without deducting income taxes, which is not in accordance with
generally accepted accounting principles. The amounts cannot be computed on an
after tax basis because the tax attributes of the Company's net operating loss
carryforwards cannot be allocated to specific properties. The Company believes
the present value of future net revenues is an important financial measure for
evaluating the relative significance of oil and natural gas properties, but it
should not be construed as an alternative to the Standardized Measure.

  Andrews Wolfcamp Field. On January 1, 1993, as part of a larger acquisition,
the Company took over operations of three leases in the Andrews Wolfcamp
Field. These leases produce primarily from the Wolfcamp and Pennsylvanian
formations at an average depth of 9,000 feet and are located in Andrews
County, Texas. The Company recognized the waterflood potential of this field
and thus began acquiring offset leases. In July 1994, the Company purchased a
100% working interest in three adjacent properties with five active wells. In
December 1994, the Company purchased 100% working interests in two additional
leases and a 93.8% working interest in a third lease. The Company purchased
several additional minor leases in 1995. The Company produced an average of
475 Bbls and 1,196 Mcf per day from 36 wells on these leases in December 1995.
The Company has begun the process of unitizing the field and under the
proposed plan of participation, the Company will have a 96.4% working interest
in the unit. The Company anticipates initiating waterflood activities in the
third quarter of 1996. Remaining proved reserves, net to the Company's
interest, were estimated by the Company's independent engineers to be 7,551
Mbbls and 2,107 Mmcf at December 31, 1995.
 
  Oakdale Red Fork Unit. Recognizing that the Oakdale Red Fork Field located
in Woods County, Oklahoma was an excellent candidate for secondary recovery,
the Company began acquiring leases in 1991. At that time, cumulative
production from the field was a total of 4.9 Mmbbls of oil from the Red Fork
Formation at an average depth of 5,800 feet. In April 1991, even though a
prior attempt by another party to unitize the field had failed, the Company
was able to effect unitization and assume operational control of the unit. The
unit was producing 30 Bbls per day when the Company installed a waterflood
project in 1991. Average daily oil and natural gas production in December 1995
was 1,471 Bbls per day. The Company increased its ownership in the unit to an
89% working interest through acquisitions in December 1994 and February 1995.
Remaining proved reserves, net to the Company's interest, were estimated by
the Company's independent engineers to be 4,246 Mbbls and 659 Mmcf at December
31, 1995.
 
  Shafter Lake San Andres Unit. On January 1, 1993, the Company became the
operator of the Shafter Lake San Andres Unit in Andrews County, Texas by
acquiring a 49% working interest in the unit from the prior operator. At that
time, this 12,720 acre unit was producing 743 Bbls per day from the
Grayburg/San Andres formation at an average depth of 4,500 feet. The Company
has since acquired an additional 14% working interest in this property through
eleven different acquisitions. In 1993, the Company expanded an east-west line
drive waterflood pattern by converting eight wells to water injection. The
Company continued expanding this pattern in 1994 and 1995 by drilling 21
additional producing wells and converting nine existing wells to water
injection. In December 1995, average daily production was 1,071 Bbls from 111
producing wells and 36 water injection wells. The Company has identified 58
additional drilling locations. Remaining proved reserves, net to the Company's
interest, were estimated by the Company's independent engineers to be 4,871
Mbbls and 1,407 Mmcf at December 31, 1995.
 
  Calumet Cottage Grove Unit. The Company recognized the secondary recovery
potential of this field, located in Canadian County, Oklahoma, in 1991. The
Company made approximately 100 separate acquisitions of leases prior to
forming the unit. During the unitization of this 11,440 acre unit, the Company
solicited approvals from 801 working interest and royalty interest owners. The
acquisition and unitization process took over 18 months to complete before the
unit was finally formed in May 1992. Average daily oil production increased
from 229 Bbls to over 3,300 Bbls within 26 months of initiating water
injection and in December 1995 was 2,986 Bbls. Remaining proved reserves, net
to the Company's 43.8% working interest, were estimated by the Company's
independent engineers to be 2,511 Mbbls at December 31, 1995.
 
  Chadbourne Ranch. The Company obtained 14 leases in the West Fort Chadbourne
Field located in Coke and Runnels Counties, Texas in September 1993 as part of
the acquisition of MJM. The Company has also leased 240 offsetting acres.
While there are multiple pay zones in this field,
 
                                      55
<PAGE>
 
the production is primarily from the Odom formation at a depth of
approximately 5,500 feet. The Company has drilled 18 wells in this field. In
December 1995, the average daily production was 632 Bbls and 1,670 Mcf from 39
wells. The Company has produced, net to its interest, 559 Mbbls and 1,379 Mmcf
since acquisition. The Company has identified four additional drilling
locations. Remaining proved reserves, net to the Company's interest, were
estimated by the Company's independent engineers to be 1,089 Mbbls and 3,151
Mmcf at December 31, 1995.
 
  McElroy. On July 1, 1991, the Company acquired a 100% working interest in
the Hardwicke University Section 48 lease in Upton County, Texas. The lease is
on the eastern flank of the McElroy Field and produces from the Grayburg/San
Andres formation from an average depth of 3,600 feet. Cumulative primary
production from this 160 acre lease is over 3.0 Mmbbls of primary oil. In
October 1992, the Company initiated a waterflood program by drilling six
injection wells and one producing well and converting one existing well to
injection. In September 1993, the Company acquired a 100% working interest in
four offsetting leases totaling 240 acres. Response from the waterflood has
not met the initial projections of the Company's engineers and as a result,
the expansion of waterflood operations on these leases will not occur until
performance on the existing waterflood improves. Average production in the
field in December 1995 was 112 Bbls and 143 Mcf per day. Remaining proved
reserves, net to the Company's interest, were estimated by the Company's
independent engineers to be 1,755 Mbbls and 754 Mmcf at December 31, 1995.
 
  S.M.A. Unit "B". In March 1991, the Company acquired the S.M.A. Unit "B"
along with six smaller leases in the Wichita County Regular Field in Wichita
County, Texas. Initially, the Company acquired only an 89% working interest in
the S.M.A. Unit "B." Later in 1991, the Company purchased the remaining 11%
working interest. At the time of acquisition, there were 37 producing wells
and 24 water injection wells producing 165 Bbls per day from an average depth
of 1,750 feet. The Company has since implemented a five spot waterflood
pattern by drilling 60 producing wells and 46 water injection wells and
converting 15 wells to water injection. Average daily production in December
1995 was 475 Bbls from 94 producing wells and 77 water injection wells. The
Company has identified 14 additional drilling locations. Remaining proved
reserves, net to the Company's interest, were estimated by the Company's
independent engineers to be 1,597 Mbbls at December 31, 1995. The Company is
planning to install a pilot test of an enhanced recovery process on this
property in 1996.
 
  Cutter South Mississippian Unit. In June 1993, the Company acquired nine
leases and assumed operations of 11 producing wells in the Cutter South Field
in Stevens County, Kansas. Average daily production was 80 Bbls when the
Company took over operation of these leases. Production is from the Chester
formation at an average depth of 6,000 feet, which lies below the Hugoton Gas
Field. While performing its evaluation prior to acquisition, the Company
recognized that these properties could be successfully exploited by secondary
recovery. The Company acquired three additional edge leases in this field in
1994 and 1995. On June 1, 1995, the Company was able to complete the
unitization of the field. The injection of water into the producing formation
began in November 1995. Ultimately, the Company plans to have 14 water
injection wells in the unit. The Company's working interest in the unit is
93.5% and average daily production was 82 Bbls in December 1995. Remaining
proved reserves, net to the Company's interest, were estimated by the
Company's independent engineers to be 793 Mbbls and 110 Mmcf at December 31,
1995.
 
  B.A. Bywaters. The Company acquired a 100% working interest in the B.A.
Bywaters lease on July 1, 1991. This lease is in the Wichita County Special
Field in Wichita County, Texas and produces from multiple Pennsylvanian sands
ranging from 300 to 2,000 feet. There were 26 wells producing 85 Bbls per day
when the Company took over operations in July 1991. The Company has since
drilled 33 producing wells and 29 injector wells and converted seven wells to
water injection. Production from 55 wells in December 1995 averaged 372 Bbls
per day. The Company has identified four additional drilling locations.
Remaining proved reserves, net to the Company's interest, were estimated by
the Company's independent engineers to be 1,101 Mbbls and 104 Mmcf at December
31, 1995.
 
                                      56

  L.K. Johnson. The Company acquired a 50% working interest in, and the
operations of, the L.K. Johnson lease in Foard County, Texas as part of the
MJM acquisition in September 1993. The Company has since acquired an
additional 1.5% working interest in the lease. In September 1993, production
from 18 wells averaged 163 Bbls per day from five productive horizons ranging
in depth from 2,400 to 4,000 feet. The Company has since drilled eight
additional producing wells. A pilot waterflood project began in February 1996
in the Cisco "K" field on this lease. Average daily production was 160 Bbls
and 309 Mcf in December 1995. The Company has identified 14 additional
drilling locations. Remaining proved reserves, net to the Company's interest,
were estimated by the Company's independent engineers to be 763 Mbbls and
1,104 Mmcf at December 31, 1995.
 
MARKETING
 
  With the exception of the Taurus operations (see "--Gas Plants and Gathering
Systems Operations" below), the Company does not refine or process any of the
oil and natural gas it produces. The Company's oil and natural gas production
is sold to various purchasers typically in the areas where the oil or natural
gas is produced. The Company is currently able to sell, under contract or in
the spot market, all of the oil and most of the natural gas it is capable of
producing at current market prices. Substantially all of the Company's oil and
natural gas is sold under short term contracts or contracts providing for
periodic adjustments or in the spot market; therefore, its revenue streams are
highly sensitive to changes in current market prices. Certain of the Company's
oil purchasers have paid in the past and are currently paying a premium over
posted prices and have eliminated certain quality and marketing deductions for
a portion of the Company's oil production due to the Company's control over a
significant volume of oil production in its core geographic areas. The
Company's principal market for natural gas is pipeline companies as opposed to
end users.
 
  In an effort to reduce the effects of the volatility of the price of crude
oil and natural gas on the Company's operations, management has adopted a
policy of hedging oil and gas prices whenever market prices are in excess of
the prices anticipated in the Company's operating budget and profit plan
through the use of commodity futures, options and swap agreements. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Changes in Prices and Hedging Activities" and Note 7 of Notes to
the Company's Historical Financial Statements.
 
  During the year ended December 31, 1994, sales of oil and natural gas to
Amoco Production Company and EOTT Energy Operating Limited Partnership, a
subsidiary of Enron ("EOTT"), accounted for 13% and 22%, respectively, of the
Company's consolidated revenues. During the year ended December 31, 1995,
sales of oil and natural gas to Amoco Production Company and EOTT accounted
for 10% and 18%, respectively, of the Company's consolidated revenues. EOTT is
a subsidiary of Enron and an affiliate of the Company, ECT and ECT Securities,
Inc. See "Certain Transactions." Management believes that in the event these
purchasers were to discontinue their purchases, the Company could quickly
locate other buyers and, therefore, the loss of these purchasers would not
have a material impact on the Company's financial condition or results of
operations. However, short term disruptions could occur while the Company
sought alternative buyers.
 
OIL AND NATURAL GAS RESERVES
 
  The following tables summarize certain information regarding the Company's
estimated proved oil and natural gas reserves as of December 31, 1993, 1994
and 1995. Such estimated reserves, as set forth herein and in Note 10 of Notes
to Consolidated Financial Statements, are based upon reports prepared by Lee
Keeling and Associates, Inc., independent consulting petroleum engineers. A
summary of the December 31, 1995 report is included in this Prospectus as
Annex A. Reserve estimates as of December 31, 1993 for Diamond were prepared
by Diamond's in-house engineers. All such reserves are located in the United
States. All reserves are evaluated at contract temperature and pressure which
can affect the measurement of natural gas reserves. For further information,

  (1) The number of gross wells is the total number of wells in which the
      Company owns a fractional working interest. The number of net wells is
      the sum of the fractional working interests owned by the Company in
      gross wells.
 
  For purposes of the table above, an "exploratory well" is a well drilled to
find and produce oil or natural gas in an unproved area, to find a reservoir
in a field previously found to be productive of oil or gas in another
reservoir or to extend a known reservoir. A "development well" is a well
drilled within the proven boundaries of an oil or natural gas reservoir with
the intention of completing the
 
                                      59

stratigraphic horizon known to be productive. A "dry well" is an exploratory
or development well found to be incapable of producing either oil or gas in
sufficient quantities to justify completion as an oil or natural gas well.
 
DEVELOPED AND UNDEVELOPED ACREAGE
 
  The following table sets forth the approximate gross acres and net acres of
productive properties in which the Company owned a leasehold interest as of
December 31, 1995. Gross acres refers to the total acres in which the Company
has a working interest, and net acres refers to the fractional working
interests owned by or attributable to the Company multiplied by the gross
acres in which the Company has a working interest. Developed acreage is that
acreage spaced or assignable to productive wells. Undeveloped acreage is
considered to be that acreage on which wells have not been drilled or
completed to a point that would permit the production of commercial quantities
of oil and natural gas regardless of whether or not such acreage contains
proved reserves. At December 31, 1995, the Company had no significant amount
of undeveloped acreage.

natural gas leases, rather than mineral or fee interests.
 
GAS PLANTS AND GATHERING SYSTEM OPERATIONS
 
  On April 29, 1994, the Company acquired by merger all of the issued and
outstanding common stock of Taurus, in exchange for 1.5 million shares of
Coda's Common Stock, valued at approximately $7.3 million, and approximately
$3.3 million in cash. The Company assumed existing Taurus indebtedness of
approximately $9.8 million. Taurus owns and operates three natural gas
processing facilities and approximately 700 miles of natural gas gathering
systems, primarily located in west central Texas. Taurus represented
approximately nine percent of the Company's consolidated 1995 EBITDA of
approximately $37.3 million.
 
  In July 1994, Taurus acquired ownership of the Shackelford gas processing
plant and gathering system ("Shackelford"). Taurus had previously been
operating the Shackelford system and plant under operating leases. Shackelford
consists of approximately 250 miles of pipeline located in Shackelford,
Callahan, Stephens and Throckmorton Counties, Texas. The plant is a 30,000 Mcf
per day capacity refrigerated lean oil absorption plant located near Putnam,
Texas. The steel gathering lines range in size from 3 inches to 10 inches in
diameter. There are over 100 purchase, check and sales meters. The system
utilizes 20 compressors with over 4,500 total horsepower.
 
  In January 1995, Taurus acquired the remaining 42% interest in the Hamlin
gas processing plant and gathering system ("Hamlin"). The Hamlin gathering
system consists of about 450 miles of low pressure gathering lines and twelve
compressor stations in Fisher, Cottle, Taylor, Stonewall, Jones, Haskell, King
and Knox Counties, Texas. The Hamlin plant utilizes a cryogenic process and
has a processing capacity of 20,000 Mcf per day. Gas supply to the system
consists almost entirely of high BTU casinghead gas. The Hamlin plant produces
a demethanized stream which is delivered into a products pipeline.

  The Merger Agreement originally required as a condition to JEDI's
consummation of the Merger that the Company sell Taurus on terms acceptable to
JEDI. However, negotiations with prospective purchasers for Taurus failed to
progress beyond preliminary stages and by December 1995, the Company's
management and JEDI had concluded a timely sale of Taurus upon terms
satisfactory to JEDI was not feasible or likely. Subsequently, the Merger
Agreement was amended to remove this condition. The Company intends to study
alternatives for maximizing the value of its investment in Taurus. These
alternatives could include a sale of Taurus, whether by merger, sale of all or
substantially all of the assets of Taurus or sale of all of the capital stock
of Taurus.
 
  Sales and markets. Taurus' two largest plants and gathering systems,
Shackelford and Hamlin, account for the majority of Taurus' revenue.
 
  Taurus sells its residue gas from Shackelford to a variety of large natural
gas purchasers under short-term contracts at market sensitive prices. Residue
gas from Shackelford can be delivered into either one of two major pipeline
systems. These connections provide significant marketing flexibility by giving
access to major marketing hubs in east Texas, west Texas and the Gulf Coast.
Major natural gas consuming markets in California, the Midwest, the Northeast
and along the Texas Gulf Coast can be accessed through these market hubs.
Generally, residue gas is sold under short-term contracts either at the
tailgate of the Shackelford Plant or out of the intrastate pipeline.
 
  The Shackelford Plant produces a demethanized stream which is delivered into
a products pipeline. Ethane, normal butane and natural gasoline components of
the product stream are generally sold as they enter the pipeline. The
remaining components of the product stream are then sold under short term
agreements to various customers at a central marketing point in Mont Belvieu,
Texas. A transportation and fractionation fee is paid on all gallons not sold
to the pipeline owner.
 
  Residue gas from Hamlin can be delivered into either the Palo Duro Pipeline
or the Lone Star Gas pipeline. These connections afford Taurus the opportunity
to offer residue gas from both Hamlin and Shackelford as a package which
increases the marketing flexibility and leverage of both plants. Since
assuming operation of Hamlin, Taurus has sold all residue gas under short term
contracts at market sensitive prices to a variety of large purchasers.
 
  The Hamlin Plant produces a demethanized stream which is delivered into a
products pipeline. All of Hamlin's liquids production is being sold under
agreements that provide for market index prices less a transportation and
fractionation fee.
 
  Purchases. Taurus purchases gas for Shackelford from approximately 250 wells
in Shackelford, Callahan, Stephens and Throckmorton Counties, Texas. The
majority of the production connected to the gathering system is low volume
casinghead gas. The system is operated at low pressure with lateral line
pressures ranging from 15 to 150 psi. The mainline pressure averages about 300
psi.
 
                                      61
<PAGE>
 
  Taurus utilizes two base forms of gas purchase agreements: percentage of
proceeds and fixed price. Percentage contracts provide that the seller is
allocated its proportionate share of residue gas sales and natural gas liquids
production. Fixed price contracts, which generally provide for acreage
dedications, are for primary terms of up to 20 years with annual renewals
thereafter. The purchase price to be paid is stated in the contract and is
subject to annual price redetermination if certain specific conditions are met.
 
  The natural gas connected to Shackelford is purchased under both percentage
and fixed price contracts. The majority of the natural gas connected to Hamlin
is being purchased utilizing percentage of proceeds contracts. There are about
200 natural gas purchase agreements covering over 450 wells connected to
Hamlin. Less than two percent of Taurus' purchases are from the Company's
wells.
 
MARKETS AND COMPETITION
 
  The oil and natural gas industry is highly competitive. Competitors include
major oil companies, other independent oil and natural gas concerns, and
individual producers and operators, many of which have financial resources,
staffs and facilities substantially greater than those of the Company. In
addition, the Company encounters substantial competition in acquiring oil and
natural gas properties, marketing oil and natural gas and securing trained
personnel. When possible, the Company tries to avoid open competitive bidding
for acquisition opportunities. The principal means of competition with respect
to the sale of oil and natural gas production are product availability and
price. While it is not possible for the Company to state accurately its
position in the oil and natural gas industry, the Company believes that it
represents a minor competitive factor.
 
  The market for oil, natural gas and natural gas liquids produced by the
Company depends on factors beyond its control, including domestic and foreign
political conditions, the overall level of supply of and demand for oil,
natural gas and natural gas liquids, the price of imports of oil and natural
gas, weather conditions, the price and availability of alternative fuels, the
proximity and capacity of natural gas pipelines and other transportation
facilities and overall economic conditions. The oil and natural gas industry as
a whole also competes with other industries in supplying the energy and fuel
requirements of industrial, commercial and individual consumers.
 
REGULATION
 
  The Company's operations are affected in various degrees by political
developments, federal and state laws and regulations. In particular, oil and
natural gas production operations and economics are affected by price controls,
tax and other laws relating to the petroleum industry, by changes in such laws
and by changes in administrative regulations and the interpretation and
application of such rules and regulations.
 
  Sales of oil and natural gas liquids by the Company are not regulated and are
made at market prices. The price the Company receives from the sale of these
products is affected by the cost of transporting the products to market.
Effective as of January 1, 1995, the Federal Energy Regulatory Commission
implemented regulations establishing an indexing system for transportation
rates for oil pipelines, which, generally, would index such rates to inflation,
subject to certain conditions and limitations. These regulations could increase
the cost of transporting oil and natural gas liquids by pipeline, although the
most recent adjustment generally decreased rates. These regulations are subject
to pending petitions for judicial review. The Company is not able to predict
with certainty what effect, if any, these regulations will have on it, but,
other factors being equal, the regulations may, over time, tend to increase
transportation costs or reduce wellhead prices for oil and natural gas liquids.

ENVIRONMENTAL MATTERS
 
  Operations of the Company are subject to numerous and constantly changing
federal, state and local 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 certain
permits, restrict or prohibit the types, quantities and concentration of
substances that can be released into the environment in connection with
drilling and production, restrict or prohibit drilling activities that could
impact wetlands, endangered or threatened species or other protected natural
resources and impose substantial liabilities for pollution resulting from the
Company's operations. Such laws and regulations may substantially increase the
cost of exploring for, developing or producing oil and natural gas and may
prevent or delay the commencement or continuation of a given project. In the
opinion of the Company's management, the Company is in substantial compliance
with current applicable environmental laws and regulations, and the cost of
compliance with such laws and regulations has not been material and is not
expected to be material during the next fiscal year. However, changes in
existing environmental laws and regulations or in interpretations thereof could
have a significant impact on the operating costs of the Company, as well as the
oil and natural gas industry in general. For instance, legislation has been
proposed in Congress from time to time that would reclassify certain oil and
natural gas production wastes as "hazardous wastes," which reclassification
would make exploration and production wastes subject to much more stringent
handling, disposal and clean-up requirements. State initiatives to further
regulate the disposal of oil and natural gas wastes and naturally occurring
radioactive materials are also pending in certain states, including Texas, and
these various initiatives could have a similar impact on the Company.
 
  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 that are considered to have contributed to the release of a "hazardous
substance" into the environment. These persons include the owner or operator of
the disposal site or site where the release occurred and companies that
disposed or arranged for the disposal of the hazardous substances found at the
site. Persons who are or were responsible for releases of hazardous substances
under CERCLA may be subject to joint and several liability for the costs of
cleaning up the hazardous substances that have been released into the
environment and for damages to natural resources, and it is not uncommon for
neighboring landowners and other third parties to file claims for personal
injury and property damage allegedly caused by the hazardous substances
released into the environment. The Company is able to control directly the
operation of only those wells with respect to which it acts as operator.
Notwithstanding the Company's lack of control over wells operated by others,
the failure of the operator to comply with applicable environmental regulations
may, in certain circumstances, be attributed to the Company. The Company has no
material commitments for capital expenditures to comply with existing
environmental requirements.
 
EMPLOYEES
 
  As of March 31, 1996, the Company's staff consisted of 156 full-time
employees, of whom 67 were administrative personnel, 60 were field and service-
related personnel, and 29 were personnel whose duties related to Taurus. The
Company also engages independent consulting petroleum engineers, environmental
professionals, geologists, landmen, accountants and attorneys on a fee basis.
 
LEGAL PROCEEDINGS
 
  The Company is a defendant or codefendant in minor lawsuits that have arisen
in the ordinary course of business. The Company does not expect any of these to
have a material adverse effect on the Company's consolidated financial
position.

(1) Values are calculated by subtracting the exercise price per share from the
    market value per share of the Company's Common Stock at fiscal year end,
    multiplied by the number of shares of Common Stock underlying the "in-the-
    money" options, and assumes a fair market value at fiscal year end of
    $7.4375 per share (the closing price of the Company's Common Stock on
    December 29, 1995).
 
DIRECTORS' COMPENSATION
 
  Following completion of the Merger, members of the Company's Board of
Directors will not receive compensation for any services provided in their
capacities as directors, other than the reimbursement of reasonable expenses
incurred in attending meetings of the Board of Directors.
 
  Prior to completion of the Merger, the directors were compensated pursuant
to the terms of the Compensation Plan for Directors adopted during 1990 (the
"Plan"), which applied equally to non-employee directors and directors who
were also employees of the Company. The Plan provided a quarterly director's
fee of $3,000, half in cash and half in Common Stock (at the average market
price for the quarter), plus the one time grant to each director of a warrant
to purchase up to 100,000 shares of Common Stock, at an exercise price equal
to the greater of $3.00 per share or the closing trade price on the date of
the grant. Pursuant to the Merger, each of the outstanding warrants
(irrespective of whether or not such warrant was currently exercisable) was
canceled in exchange for either (i) the cash payment of the "in-the-money"
position of the warrant or (ii) equity positions with the Company following
the Merger.
 
  Pursuant to the Plan, the cash portion of the director's compensation was
paid monthly in the month earned. The stock portion of the director's
compensation was paid quarterly, at the beginning of the quarter immediately
following the quarter in which the compensation was earned. The Plan was
amended on September 27, 1995 to provide that, effective July 1, 1995, all of
the compensation was to be paid in cash. During 1995, each director, except
for Mr. Henderson, was paid $9,000 in cash and 703 shares of Common Stock
under the Plan. Mr. Henderson was paid $8,000 in cash and 261 shares of Common
Stock under the Plan. Additionally, Messrs. Earl Ellis, David Keener and
Worthy Warnack received $20,000, $15,000 and $15,000, respectively, for their
service on the Board of Directors' Special Committee which was formed in April
1995.
 
EMPLOYMENT AGREEMENTS
 
  Messrs. Douglas H. Miller, Jarl P. Johnson, Grant W. Henderson, Randell A.
Bodenhamer, J. William Freeman and J.W. Spencer, III, have entered into
employment agreements (the "Employment Agreements") with the Company which
became effective on February 16, 1996. The Employment Agreements are for a
period of five years from February 16, 1996 (three years in the case of
Messrs. Johnson and Spencer) and provide for the payment of base salaries,
together with other benefits generally available to employees of the Company,
and positions with the Company as set forth below:

</TABLE>
 
  Each of these persons would receive his salary for the remaining term of his
Employment Agreement if the Company were to terminate his Employment Agreement
other than for cause. The Employment Agreements provide that the employees
agree not to compete with the Company for a period of six months after their
voluntary termination or termination for cause; in the case of Mr. Miller, the
covenant not to compete is for a period of two years, except that the
noncompetition period is one year in the event of incapacity, involuntary
termination other than for cause or his resignation due to a breach by the
Company of Mr. Miller's Employment Agreement.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Board of Directors had a Compensation Committee consisting of Walter
Hailey and Frank Horlock. This committee did not meet in 1995.
 
                             CERTAIN TRANSACTIONS
 
CERTAIN INDEBTEDNESS
 
  In connection with the acquisition of Taurus, Mr. Lohman made a loan to the
Company for the sum of $1.0 million in exchange for a subordinated promissory
note from the Company having a term of three years, payable in three equal
annual installments of principal plus accrued interest calculated at the rate
of 7% per annum. Such amount represented the highest outstanding balance owed
by the Company to Mr. Lohman in 1995. On December 31, 1995, the principal
balance remaining on the promissory note was $666,667. On February 16, 1996,
the Company repaid Mr. Lohman the aggregate amount of principal and interest
owed by the Company to Mr. Lohman.
 
  Douglas H. Miller, Chairman of the Board and Chief Executive Officer of the
Company, was indebted to the Company in an aggregate amount of $83,589 as of
June 30, 1995. Such amount represented the highest outstanding balance owed by
Mr. Miller to the Company in 1995. The indebtedness consisted of three
promissory notes, dated as of May 31, 1992, October 1, 1994, and May 31, 1995,
in the original principal amounts of $19,022, $19,250 and $69,526,
respectively. The October 1, 1994 note bore interest at 3.75%, and the
remaining two notes bore interest at the prime rate charged by NationsBank
plus one percent. Except for the promissory note in the original principal
amount of $19,250, the proceeds from which were used to purchase Common Stock
under the Company's 1994 Employee Stock Purchase Plan, all indebtedness
represented Mr. Miller's miscellaneous personal expenses. On February 20,
1996, Mr. Miller repaid the Company an aggregate amount of $90,105
representing all indebtedness owed by Mr. Miller to the Company.
 
  In May 1995, Jarl P. Johnson, Vice Chairman of the Board and President of
Diamond, repaid Diamond the sum of $236,194, representing full payment of
indebtedness evidenced by a promissory note, payable on demand, bearing
interest at the rate of 10% per annum. Such amount represented the highest
outstanding balance owed by Mr. Johnson to the Company in 1995. The
indebtedness was
 
                                      70
<PAGE>
 
secured by a pledge of certain shares of Common Stock owned by Mr. Johnson.
The indebtedness arose in June 1990, prior to the Company's acquisition of
Diamond, when Mr. Johnson and certain other Diamond shareholders obtained
certain properties of Diamond Energy Operating Company in exchange for notes.
The properties were then contributed to Diamond A Inc. in exchange for shares
of Diamond A Inc., which shares were in turn pledged to secure the notes.
 
SUBSCRIPTION AGREEMENT
 
  CAI entered into a Subscription Agreement dated as of October 30, 1995, as
amended by Amendment No. 1 to Subscription Agreement dated as of January 10,
1996, with members of the Management Group (as amended, the "Subscription
Agreement") which provided for the acquisition by such persons of CAI common
stock and the grant to them of nonqualified stock options to purchase shares
of post-Merger common stock (the "Replacement Options") of Coda. Under the
Subscription Agreement, each member of the Management Group who acquired CAI
common stock paid $100 per share for shares thereof, which is the same price
per share paid by JEDI for the remaining shares of CAI common stock. Under the
Subscription Agreement, the Management Group acquired CAI common stock
immediately prior to the effective time of the Merger in exchange for varying
combinations of (i) proceeds from limited recourse promissory notes payable to
CAI in the aggregate principal amount of $937,300 (the "Promissory Notes"),
(ii) Common Stock, which was valued for this purpose at $7.75 per share, and
(iii) cash. The CAI common stock so acquired was not registered under the
Securities Act or any state securities laws and does not have the benefit of
any registration rights, but is subject to the Stockholders Agreement
described below. See "--Stockholders Agreement." By virtue of the Merger, each
share of CAI common stock was converted into one share of Coda common stock.
 
  The Subscription Agreement provided that the Specified Options (representing
certain options to purchase Common Stock held by certain members of the
Management Group) and Specified Warrants (representing certain warrants to
purchase Common Stock held by certain members of the Management Group) would
not be exercised prior to the effective time of the Merger and would, as of
the effective time, be canceled without exercise and without payment of
consideration. Concurrently, the Management Group entered into Nonstatutory
Stock Option Agreements governing the Replacement Options that provided for
the right for a period of 10 years from and after the effective time of the
Merger to purchase shares of post-Merger Coda common stock for $0.01 per
share. However, the Replacement Options may only be exercised while the holder
remains an employee of the Company and for a limited period of time
thereafter. The number of shares of Coda common stock underlying the
Replacement Options each member of the Management Group received is based on
the amount of cash the holder would have received if his Specified Options or
Specified Warrants had been converted into cash in the Merger on the same
basis as other outstanding options and warrants to purchase Common Stock were
converted, divided by the $100 per share purchase price paid by JEDI and the
other Management Group members for their shares of CAI common stock. Thus, if
the Replacement Options are exercised, the holders will have effectively paid
the same purchase price per share as JEDI and the Management Group paid for
their shares of common stock of Coda.
 
  The Promissory Notes will be due on February 16, 2001, bear interest at the
mid-term applicable federal rate (annual compounding) for the month February
1996 (5.61%), are secured by the Company common stock purchased with the
proceeds thereof and certain rights of the maker under the Stockholders
Agreement described below, and provide that in no event will an individual
maker's liability thereunder for any deficiency on his respective Promissory
Note (after the sale and disposition of all collateral securing same) exceed
35% of the original principal balance of the Promissory Note.

STOCKHOLDERS AGREEMENT
 
  CAI, JEDI and the Management Group entered into a Stockholders Agreement
dated as of October 30, 1995, as amended by Amendment No. 1 to Stockholders
Agreement dated as of January 10, 1996 (as amended, the "Stockholders
Agreement"), which provides generally that all parties, including JEDI and the
Management Group, (i) have rights of first refusal to acquire additional shares
of common stock of Coda that may be issued by Coda and (ii) are restricted from
transferring their Coda common stock. Coda has a right to match any third party
offer to purchase shares of Coda common stock from any stockholder, and, in the
event that Coda does not purchase those shares, the other stockholders may have
a right to include a pro rata portion of their Coda common stock in the
transaction. The Stockholders Agreement provides that, if the employment of a
member of the Management Group terminates for any reason (including death or
disability) other than his voluntary termination (except upon retirement at age
65 or older or the expiration of the term of any employment agreement he has
with Coda) or his termination by Coda for cause, then Coda shall have a right
to purchase such member's shares of Coda common stock at a purchase price to be
determined from time to time by Coda pursuant to a formula that values the
shares on the basis of a comparison of the discretionary cash flow and EBITDA
(as defined therein) of the Company and a group of peer companies. The
Stockholders Agreement also provides that, if the employment of a member of the
Management Group terminates for any reason other than voluntary termination or
termination of such member for cause, then such member shall have the right to
require Coda to purchase such member's shares of Coda common stock based on the
previously described formula. The purchase price under the formula will vary
depending on the financial performance of the Company and the group of peer
companies. The Stockholders Agreement provides that each member of the
Management Group shall have the right (the "Special Management Rights") to
receive from JEDI, upon the occurrence of certain events (generally an initial
public offering, a business combination with another person or the liquidation
of Coda) (each, a "Trigger Event"), an amount, which is payable in cash or
additional shares of Coda common stock depending upon the cause of the Trigger
Event, designed to result in the Management Group receiving in connection with
the Trigger Event one-third of the proceeds, attributable to the shares of Coda
common stock purchased by JEDI, above the amount of proceeds necessary for JEDI
to achieve an internal annual rate of return on that investment of 15%. The
individual member's interest in such Special Management Rights is proportional
to such member's ownership of the fully diluted common stock of Coda. The
Stockholders Agreement also provides that if the employment of a member of the
Management Group terminates, his Special Management Rights shall terminate and,
if the termination is other than a voluntary termination or a termination for
cause, he may be entitled to receive an amount based on the discretionary cash
flow and EBITDA formula discussed above. The Stockholders Agreement further
provides that, after the effective time of the Merger, Coda will establish an
employee benefit plan for the benefit of its employees who are not members of
the Management Group and will contribute to the plan 1,900 shares of Coda
common stock. Furthermore, pursuant to the Stockholders Agreement, 4% of the
Special Management Rights will be allocated thereto.
 
  The Stockholders Agreement will terminate and no party thereto will have any
further obligations or rights thereunder upon the earliest to occur of (i) the
termination of the Merger Agreement in accordance with its terms, (ii) October
30, 2005, (iii) the date on which an initial public offering of Coda common
stock or any business transaction involving Coda whereby Coda common stock
becomes a publicly traded security is consummated, (iv) the date of the
dissolution, liquidation or winding-up of Coda and (v) the date of the delivery
to Coda of a written termination notice executed by certain parties to the
Stockholders Agreement.

ENRON
 
  Enron is the parent of ECT and accordingly may be deemed to control
indirectly both JEDI and the Company. Enron and certain of its subsidiaries and
other affiliates collectively participate in nearly all phases of the oil and
natural gas industry and are, therefore, competitors of the Company. In
addition, ECT and JEDI have provided, and may in the future provide, and ECT
Securities Corp. has assisted, and may in the future assist, in arranging,
financing to non-affiliated participants in the oil and natural gas industry
who are or may become competitors of the Company. Because of these various
conflicting interests, ECT, the Company, JEDI and the Management Group have
entered into the Business Opportunity Agreement which is intended to make it
clear that Enron and its affiliates have no duty to make business opportunities
available to the Company in most circumstances. The Business Opportunity
Agreement also provides that ECT and its affiliates may pursue certain business
opportunities to the exclusion of the Company. The Business Opportunity
Agreement may limit the business opportunities available to the Company. In
addition, pursuant to the Business Opportunity Agreement there may be
circumstances in which the Company will offer business opportunities to certain
affiliates of Enron. If an Enron affiliate is offered such an opportunity and
decides to pursue it, the Company may be unable to pursue it. See "Offer and
Resale" for a discussion of ECT Securities, Inc.'s involvement in the Offering.
 
  During the fiscal year ended December 31, 1995, EOTT made payments to the
Company aggregating approximately $17.7 million for oil purchases. See
"Business--Marketing." Furthermore, during the fiscal year ended December 31,
1995, Enron Industrial Natural Gas Company, an indirect subsidiary of Enron and
an affiliate of JEDI, made payments aggregating approximately $1.8 million for
purchases of natural gas from Taurus.

                         DESCRIPTION OF EXCHANGE NOTES
 
GENERAL
 
  The Exchange Notes will be issued pursuant to an Indenture (the "Indenture")
among the Company, the initial Guarantors and Texas Commerce Bank National
Association, as trustee (the "Trustee"). The Exchange Notes will evidence the
same indebtedness as the Private Notes (which they replace) and will be issued
under, and be entitled to the benefits of, the Indenture. The form and terms
of the Exchange Notes are the same as the form and terms of the Private Notes
except that (i) the Exchange Notes will bear the Series B designation, (ii)
the Exchange Notes will have been registered under the Securities Act and,
therefore, the Exchange Notes will not bear legends restricting the transfer
thereof and (iii) holders of the Exchange Notes will not be entitled to
certain rights of holders of the Private Notes under the Registration Rights
Agreement, which rights will terminate upon consummation of the Exchange
Offer. The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act of 1939
(the "Trust Indenture Act"). The Notes are subject to all such terms, and
Holders of Notes are referred to the Indenture and the Trust Indenture Act for
a statement thereof. The following summary of certain provisions of the
Indenture does not purport to be complete and is qualified in its entirety by
reference to the Indenture, including the definitions therein of certain terms
used below. The definitions of certain terms used in the following summary are
set forth below under "--Certain Definitions."
 
  The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to Senior Debt. See "Risk Factors--
Subordination." The Notes will be guaranteed on a senior subordinated basis by
all of the Company's current Subsidiaries and future Restricted Subsidiaries.
The obligation of the Restricted Subsidiaries under such guarantees will be
general unsecured obligations of such Restricted Subsidiaries and will be
subordinated in right of payment to all obligations of such Restricted
Subsidiaries in respect of Senior Debt. See "--Subsidiary Guarantees" and
"Risk Factors--Subordination."
 
  While Coda itself owns and operates a significant portion of the Company's
consolidated assets, Coda currently depends to a large degree on cash flow
generated by Diamond, and to a lesser degree on cash flow generated by Taurus.
Electra does not currently hold or operate any assets. All of Coda's current
subsidiaries are guarantors of the Notes and are not obligors on any
indebtedness for borrowed money (excluding intercompany indebtedness and as
guarantors under the Credit Agreement). There are no contractual restrictions
on the ability to pay dividends or make any other distributions of funds by
the Guarantors to Coda. The corporation laws of each of the states under which
the Guarantors are chartered contain certain restrictions on the ability of
corporations to pay dividends or make other distributions to holders of such
corporation's capital stock.
 
  As of the date of the Indenture, all of the Company's Subsidiaries will be
Restricted Subsidiaries. However, under certain circumstances, the Company
will be able to designate current or future Subsidiaries as Unrestricted
Subsidiaries. Unrestricted Subsidiaries will not be subject to many of the
restrictive covenants set forth in the Indenture.
 
  For purposes of this section, the term "Company" means Coda Energy, Inc. and
the term "Taurus" has the meaning given under the caption "--Certain
Definitions."
 
SUBORDINATION
 
  The payment of principal of, premium, if any, and interest and Liquidated
Damages, if any, on the Notes and any other payment obligations of the Company
in respect of the Notes (including any obligation to repurchase the Notes)
will be subordinated in certain circumstances in right of payment, as set
forth in the Indenture, to the prior payment in full of all Senior Debt,
whether outstanding on the date of the Indenture or thereafter incurred.
 
                                      74

  Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, or
in an assignment for the benefit of creditors or any marshalling of the
Company's assets and liabilities, the holders of Senior Debt will be entitled
to receive payment in full of all Obligations due in respect of such Senior
Debt (including interest after the commencement of any such proceeding at the
rate specified in the applicable Senior Debt) before the Holders of Notes will
be entitled to receive any payment with respect to the Notes, and until all
Obligations with respect to Senior Debt are paid in full, any distribution to
which the Holders of Notes would be entitled shall be made to the holders of
Senior Debt (except that Holders of Notes may receive securities that are
subordinated at least to the same extent as the Notes to Senior Debt and any
securities issued in exchange for Senior Debt (provided that receipt of such
securities will not cause the Notes to be treated in any case or proceeding or
similar event described in this paragraph in the same class of claims as
Senior Debt or any class of claims pari passu with Senior Debt for any payment
or distribution) and payments made from the trust described under "--Legal
Defeasance and Covenant Defeasance").
 
  The Company also may not make any payment upon or in respect of the Notes
(except in such subordinated securities or from the trust described under "--
Legal Defeasance and Covenant Defeasance") if (i) a default in the payment of
the principal of, premium, if any, or interest on Designated Senior Debt
occurs and is continuing beyond any applicable period of grace or (ii) any
other default occurs and is continuing with respect to Designated Senior Debt
that permits, or with the giving of notice or passage of time or both (unless
cured or waived) will permit, holders of the Designated Senior Debt as to
which such default relates to accelerate its maturity and the Trustee receives
a notice of such default (a "Payment Blockage Notice") from the Company or the
holders of any Designated Senior Debt. Payments on the Notes shall be resumed
(a) in the case of a payment default, upon the date on which such default is
cured or waived and (b) in case of a nonpayment default, the earlier of the
date on which such nonpayment default is cured or waived or 179 days after the
date on which the applicable Payment Blockage Notice is received, unless the
maturity of any Designated Senior Debt has been accelerated. No new period of
payment blockage may be commenced unless and until (i) 360 days have elapsed
since the date of commencement of the payment blockage period resulting from
the immediately prior Payment Blockage Notice and (ii) all scheduled payments
of principal, premium, if any, and interest on the Notes that have come due
have been paid in full in cash. No nonpayment default that existed or was
continuing on the date of delivery of any Payment Blockage Notice to the
Trustee shall be, or be made, the basis for a subsequent Payment Blockage
Notice.
 
  The Indenture will further require that the Company promptly notify holders
of Senior Debt if payment of the Notes is accelerated because of an Event of
Default.
 
  As a result of the subordination provisions described above, in the event of
a liquidation or insolvency of the Company, Holders of Notes may recover less
ratably than creditors of the Company who are holders of Senior Debt. On a pro
forma basis, after giving effect to the Merger and the sale of the Private
Notes and the application of the proceeds therefrom, the principal amount of
Senior Debt outstanding at December 31, 1995 would have been approximately
$86.9 million, which includes $85.3 million of borrowings under the Credit
Agreement. See "Description of Other Debt." The Indenture will limit, subject
to certain financial tests, the amount of additional Indebtedness, including
Senior Debt, that the Company and its Restricted Subsidiaries can incur. See
"--Certain Covenants--Incurrence of Indebtedness and Issuance of Preferred
Stock."
 
SUBSIDIARY GUARANTEES
 
  The Company's payment obligations under the Notes will be jointly and
severally and unconditionally guaranteed (the "Subsidiary Guarantees") by the
Guarantors. The Subsidiary
 
                                      75
<PAGE>
 
Guarantee of each Guarantor will be subordinated (to the same extent and in the
same manner as the Notes are subordinated to the Senior Debt) to the prior
payment in full of all Senior Debt of such Guarantor, which, on a pro forma
basis, after giving effect to the Merger and the sale of the Private Notes and
the application of proceeds therefrom, would have been approximately $86.9
million as of December 31, 1995. The obligations of each Guarantor under its
Subsidiary Guarantee will be limited so as not to constitute a fraudulent
conveyance under applicable law. See, however, "Risk Factors--Fraudulent
Conveyances."
 
  The Indenture will provide that no Guarantor may consolidate with or merge
with or into (whether or not such Guarantor is the surviving Person), another
corporation, Person or entity whether or not affiliated with such Guarantor
unless (i) subject to the provisions of the following paragraph, the Person
formed by or surviving any such consolidation or merger (if other than such
Guarantor) assumes all the obligations of such Guarantor, pursuant to a
supplemental indenture in form and substance reasonably satisfactory to the
Trustee in respect of the Notes, the Indenture and such Guarantor's Subsidiary
Guarantee; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; and (iii) such transaction does not violate any of
the covenants described under the heading "--Certain Covenants."
 
  The Indenture will provide that in the event of a sale or other disposition
of all or substantially all of the assets of any Guarantor to a third party or
an Unrestricted Subsidiary in a transaction that does not violate any of the
covenants in the Indenture, by way of merger, consolidation or otherwise, or a
sale or other disposition of all of the capital stock of any Guarantor, then
such Guarantor (in the event of a sale or other disposition, by way of such a
merger, consolidation or otherwise, of all of the capital stock of such
Guarantor) or the corporation acquiring the property (in the event of a sale or
other disposition of all of the assets of such Guarantor) will be released from
and relieved of any obligations under its Subsidiary Guarantee; provided that
the Net Proceeds of such sale or other disposition are applied in accordance
with the covenant described under the caption "--Repurchase at the Option of
Holders--Asset Sales."
 
  Any Guarantor that is designated an Unrestricted Subsidiary in accordance
with the terms of the Indenture shall be released from and relieved of its
obligations under its Subsidiary Guarantee and any Unrestricted Subsidiary that
ceases to be an Unrestricted Subsidiary will be required to execute a
Subsidiary Guarantee in accordance with the terms of the Indenture.
 
PRINCIPAL, MATURITY AND INTEREST
 
  The Notes will be limited in aggregate principal amount to $110.0 million and
will mature on April 1, 2006. Interest on the Notes will accrue at the rate of
10 1/2% per annum and will be payable semiannually in arrears on April 1 and
October 1, commencing on October 1, 1996, to Holders of record on the
immediately preceding March 15 and September 15. Interest on the Notes will
accrue from the most recent date on which interest has been paid or, if no
interest has been paid, from the date of original issuance of the Exchange
Notes, plus an amount equal to the accrued interest on the Private Notes from
the date of initial delivery to the date of exchange thereof for the Exchange
Notes. Interest will be computed on the basis of a 360-day year comprised of
twelve 30-day months. Principal, premium, if any, interest and Liquidated
Damages, if any, on the Notes will be payable at the office or agency of the
Company maintained for such purpose within the City and State of New York or,
at the option of the Company, payment of interest and Liquidated Damages, if
any, may be made by check mailed to the Holders of the Notes at their
respective addresses set forth in the register of Holders of Notes; provided
that all payments with respect to Notes having an aggregate principal amount of
$5.0 million or more the Holders of which have given wire transfer instructions
to the Company at least ten business days prior to the applicable payment date
will be required to be made by wire transfer of immediately available funds to
the accounts specified by the Holders thereof. Until otherwise designated by
the Company, the Company's office or agency in New York will be the office of
the
 
                                       76
<PAGE>
 
Trustee maintained for such purpose. The Exchange Notes will be issued in
registered form, without coupons, and in denominations of $1,000 and integral
multiples of $1,000 in excess thereof.
 
OPTIONAL REDEMPTION
 
  The Notes will not be redeemable at the Company's option prior to April 1,
2001, except as provided below. Thereafter, the Notes will be subject to
redemption at the option of the Company, in whole or in part, upon not less
than 30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest and Liquidated Damages, if any, thereon to the applicable redemption
date, if redeemed during the twelve-month period beginning on April 1 of the
years indicated below:
 
<TABLE>
<CAPTION>
      YEAR                                                            PERCENTAGE
      ----                                                            ----------
      <S>                                                             <C>

      2002...........................................................  102.625%
      2003 and thereafter............................................      100%
</TABLE>
 
  Notwithstanding the foregoing, before March 12, 1999, the Company may, on any
one or more occasions, redeem up to $27.5 million in aggregate principal amount
of Notes at a redemption price of 110.5% of the principal amount thereof plus
accrued and unpaid interest and Liquidated Damages, if any, thereon to the
redemption date, with the net proceeds of an offering of common equity of the
Company; provided that at least $82.5 million in aggregate principal amount of
Notes must remain outstanding immediately after the occurrence of such
redemption; and provided, further, that any such redemption shall occur within
75 days of the date of the closing of such offering of common equity of the
Company.
 
SELECTION AND NOTICE
 
  If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which
the Notes are listed, or, if the Notes are not so listed, on a pro rata basis,
by lot or by such method as the Trustee shall deem fair and appropriate;
provided that no Notes of $1,000 or less shall be redeemed in part. Notices of
redemption shall be mailed by first class mail at least 30 but not more than 60
days before the redemption date to each Holder of Notes to be redeemed at its
registered address. If any Note is to be redeemed in part only, the notice of
redemption that relates to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the Holder thereof
upon cancellation of the original Note. On and after the redemption date,
interest ceases to accrue on Notes or portions of them called for redemption.
 
MANDATORY REDEMPTION
 
  Except as set forth below under "--Repurchase at the Option of Holders," the
Company is not required to make mandatory redemption or sinking fund payments
with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
 Change of Control
 
  Upon the occurrence of a Change of Control (as defined below under "--Certain
Definitions"), each Holder of Notes will have the right to require the Company
to repurchase all or any part (equal to $1,000 or an integral multiple thereof)
of such Holder's Notes pursuant to the offer described below (the "Change of
Control Offer") at an offer price in cash equal to 101% of the aggregate
principal amount thereof plus accrued and unpaid interest and Liquidated
Damages, if any, thereon to the date
 
                                       77
<PAGE>
 
of purchase (the "Change of Control Payment"). Within 30 days following any
Change of Control, the Company will mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase Notes pursuant to the procedures required by the Indenture and
described in such notice. The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of the Notes as a result of a Change of Control.
 
  On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating
the aggregate principal amount of Notes or portions thereof being purchased by
the Company. The Paying Agent will promptly mail to each Holder of Notes so
tendered the Change of Control Payment for such Notes, and the Trustee will
promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of
the Notes surrendered, if any; provided that each such new Note will be in a
principal amount of $1,000 or an integral multiple thereof. The Indenture will
provide that, prior to complying with the provisions of this covenant, but in
any event within 90 days following a Change of Control, the Company will either
repay all outstanding Senior Debt or obtain the requisite consents, if any,
under all agreements governing outstanding Senior Debt to permit the repurchase
of Notes required by this covenant. The degree to which the Company is
leveraged upon a Change of Control could prevent it from repaying outstanding
Senior Debt (or obtaining the consent of the senior lenders to a repurchase of
Notes) and from repurchasing Exchange Notes tendered to it upon such Change of
Control. The Company will publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment
Date.
 
  Holders of not less than a majority in aggregate principal amount of Notes
then outstanding may waive these Change of Control repurchase requirements. The
Change of Control provisions described above will be applicable whether or not
any other provisions of the Indenture are applicable. Except as described above
with respect to a Change of Control, the Indenture does not contain provisions
that permit the Holders of the Notes to require that the Company repurchase or
redeem the Notes in the event of a takeover, recapitalization or similar
transaction.
 
  The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set
forth in the Indenture applicable to a Change of Control Offer made by the
Company and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer.
 
  The definition of Change of Control encompasses a transaction which is
approved by the Company's Board of Directors. The definition also includes a
phrase relating to the sale, lease, transfer, conveyance or other disposition
of "all or substantially all" of the assets of the Company and its Subsidiaries
taken as a whole. Although there is a developing body of case law interpreting
the phrase "substantially all," there is no precise established definition of
the phrase under applicable law. Accordingly, the ability of a Holder of Notes
to require the Company to repurchase such Notes as a result of a sale, lease,
transfer, conveyance or other disposition of less than all of the assets of the
Company and its Subsidiaries taken as a whole to another Person or group may be
uncertain.
 
  The Credit Agreement currently prohibits the Company from purchasing any
Notes, and also provides that certain change of control events with respect to
the Company would constitute a default thereunder. Any future credit agreements
or other agreements relating to Senior Indebtedness to which the Company
becomes a party may contain similar restrictions and provisions. In the event a
Change
 
                                       78
<PAGE>
 
of Control occurs at a time when the Company is prohibited from purchasing
Notes, the Company could seek the consent of its lenders to the purchase of
Notes or could attempt to refinance the borrowings that contain such
prohibition. If the Company does not obtain such a consent or repay such
borrowings, the Company will remain prohibited from purchasing Notes. In such
case, the Company's failure to purchase tendered Notes would constitute an
Event of Default under the Indenture. In such circumstances, the subordination
provisions in the Indenture would likely restrict payments to the Holders of
Notes by either Coda or the Guarantors.
 
  The existence of a Holder's right to require the Company to repurchase such
Holder's Notes upon the occurrence of a Change of Control may deter a third
party from seeking to acquire the Company in a transaction that would
constitute a Change of Control.
 
 Asset Sales
 
  The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, engage in an Asset Sale unless (i) the
Company (or the Restricted Subsidiary, as the case may be) receives
consideration at the time of such Asset Sale at least equal to the fair market
value (as determined by a resolution of the Board of Directors set forth in an
Officers' Certificate delivered to the Trustee, which determination shall be
conclusive evidence of compliance with this provision) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 85% of the
consideration therefor received by the Company or such Restricted Subsidiary is
in the form of cash or Cash Equivalents; provided that the amount of (x) any
liabilities (as shown on the Company's or such Restricted Subsidiary's most
recent balance sheet), of the Company or any Restricted Subsidiary (other than
contingent liabilities and liabilities that are by their terms subordinated to
the Notes or any guarantee thereof) that are assumed by the transferee of any
such assets pursuant to a customary novation agreement that releases the
Company or such Restricted Subsidiary from further liability and (y) any Liquid
Securities received by the Company or any such Restricted Subsidiary from such
transferee that are converted by the Company or such Restricted Subsidiary into
cash within 180 days of closing such Asset Sale, shall be deemed to be cash for
purposes of this provision (to the extent of the cash received).
 
  Within 270 days after the receipt of any Net Proceeds from an Asset Sale, the
Company may apply such Net Proceeds, at its option, (a) to reduce Senior Debt,
(b) to acquire a controlling interest in another Oil and Gas Business, to make
a Permitted Business Investment, to make capital expenditures in respect of the
Company's or its Restricted Subsidiaries' Oil and Gas Business, or to purchase
long-term assets that are used or useful in the Oil and Gas Business or (c) in
the case of any Net Proceeds derived from an Asset Sale in respect of Taurus,
to redeem JEDI Preferred Stock. Pending the final application of any such Net
Proceeds, the Company may temporarily reduce Senior Debt that is revolving debt
or otherwise invest such Net Proceeds in any manner that is not prohibited by
the Indenture. Any Net Proceeds from Asset Sales that are not applied or
invested as provided in the first sentence of this paragraph will (after the
expiration of the periods specified in this paragraph) be deemed to constitute
"Excess Proceeds."
 
  When the aggregate amount of Excess Proceeds exceeds $10.0 million, the
Company will be required to make an offer to all Holders of Notes and, to the
extent required by the terms thereof, to all holders or lenders of Pari Passu
Indebtedness (an "Asset Sale Offer") to purchase the maximum principal amount
of Notes and any such Pari Passu Indebtedness to which the Asset Sale Offer
applies that may be purchased out of the Excess Proceeds, at an offer price in
cash in an amount equal to 100% of the principal amount thereof plus accrued
and unpaid interest and Liquidated Damages, if any, thereon to the date of
purchase, in accordance with the procedures set forth in the Indenture or the
agreements governing the Pari Passu Indebtedness, as applicable. To the extent
that the aggregate amount of Notes tendered or Pari Passu Indebtedness tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company
may use any remaining Excess Proceeds for
 
                                       79
<PAGE>
 
general corporate purposes. If the aggregate principal amount of Notes
surrendered by Holders thereof and Pari Passu Indebtedness surrendered by
holders or lenders thereof, collectively, exceeds the amount of Excess
Proceeds, the Trustee shall select the Notes and Pari Passu Indebtedness to be
purchased on a pro rata basis, based on the aggregate principal amount (or
accreted value, as applicable) thereof surrendered in such Asset Sale Offer.
Upon completion of such Asset Sale Offer, the amount of Excess Proceeds shall
be reset at zero.
 
  The Credit Agreement may prohibit the Company from purchasing any Notes and
also provides that certain change of control events with respect to the Company
would constitute a default thereunder. Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control
or Asset Sale Offer occurs at a time when the Company is prohibited from
purchasing Notes, the Company could seek the consent of its lenders to the
purchase of or could attempt to refinance the borrowings that contain such
prohibition. If the Company does not obtain such a consent or repay such
borrowings, the Company may remain prohibited from purchasing Notes. In such
case, the Company's failure to purchase tendered Notes would constitute an
Event of Default under the Indenture which would, in turn, constitute a default
under the Credit Agreement. In such circumstances, the subordination provisions
in the Indenture would likely restrict payments to the Holders of Notes.
 
CERTAIN COVENANTS
 
 Restricted Payments
 
  The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay
any dividend or make any other payment or distribution on account of the
Company's Equity Interests (including, without limitation, any payment in
connection with any merger or consolidation involving the Company) or to the
direct or indirect holders of the Company's Equity Interests in their capacity
as such (other than dividends or distributions payable in Equity Interests
(other than Disqualified Stock) of the Company); (ii) purchase, redeem or
otherwise acquire or retire for value any Equity Interests of the Company or
any direct or indirect parent or other Affiliate of the Company that is not a
Subsidiary of the Company; (iii) make any principal payment on, or purchase,
redeem, defease or otherwise acquire or retire for value any Indebtedness that
is subordinated to the Notes, except at final maturity; or (iv) make any
Restricted Investment (all such payments and other actions set forth in clauses
(i) through (iv) above being collectively referred to as "Restricted
Payments"), unless, at the time of and after giving effect to such Restricted
Payment:
 
    (a) no Default or Event of Default shall have occurred and be continuing
  or would occur as a consequence thereof; and
 
    (b) the Company would, at the time of such Restricted Payment and after
  giving pro forma effect thereto as if such Restricted Payment had been made
  at the beginning of the applicable four-quarter period, have been permitted
  to incur at least $1.00 of additional Indebtedness pursuant to the Fixed
  Charge Coverage Ratio test set forth in the first paragraph of the covenant
  described below under the caption "--Incurrence of Indebtedness and
  Issuance of Preferred Stock"; and
 
    (c) such Restricted Payment, together with the aggregate of all other
  Restricted Payments made by the Company and its Restricted Subsidiaries
  after the date of the Indenture (excluding Restricted Payments permitted by
  clauses (2), (3), (5), (6) and (7) of the next succeeding paragraph), is
  less than the sum of (i) 50% of the Consolidated Net Income of the Company
  for the period (taken as one accounting period) from the beginning of the
  first fiscal quarter commencing after the date of the Indenture to the end
  of the Company's most recently ended fiscal quarter for which internal
  financial statements are available at the time of such Restricted
 
                                       80
<PAGE>
 
  Payment (or, if such Consolidated Net Income for such period is a deficit,
  less 100% of such deficit), plus (ii) 100% of the aggregate net cash
  proceeds received by the Company from the issue or sale since the date of
  the Indenture of Equity Interests of the Company (other than the JEDI
  Preferred Stock) or of debt securities of the Company that have been
  converted into or exchanged for such Equity Interests (other than Equity
  Interests (or convertible debt securities) sold to a Subsidiary of the
  Company and other than Disqualified Stock or debt securities that have been
  converted into Disqualified Stock), plus (iii) to the extent that any
  Restricted Investment that was made after the date of the Indenture is sold
  for cash or otherwise liquidated or repaid for cash, the lesser of (A) the
  net proceeds of such sale, liquidation or repayment and (B) the initial
  amount of such Restricted Investment, plus (iv) 50% of any dividends
  received by the Company or a Wholly Owned Restricted Subsidiary after the
  date of the Indenture from an Unrestricted Subsidiary of the Company.
 
  The foregoing provisions will not prohibit (1) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (2) the redemption, repurchase, retirement or other acquisition of
any Equity Interests of the Company in exchange for, or out of the proceeds of,
the substantially concurrent sale (other than to a Subsidiary of the Company)
of other Equity Interests of the Company (other than any Disqualified Stock);
provided that the amount of any such net cash proceeds that are utilized for
any such redemption, repurchase, retirement or other acquisition shall be
excluded from clause (c)(ii) of the preceding paragraph; (3) the defeasance,
redemption or repurchase of subordinated Indebtedness with the net cash
proceeds from an incurrence of Permitted Refinancing Debt or the substantially
concurrent sale (other than to a Subsidiary of the Company) of Equity Interests
of the Company (other than Disqualified Stock); provided that the amount of any
such net cash proceeds that are utilized for any such redemption, repurchase,
retirement or other acquisition shall be excluded from clause (c)(ii) of the
preceding paragraph; (4) the repurchase, redemption or other acquisition or
retirement for value of any Equity Interests of the Company or any Restricted
Subsidiary of the Company held by any of the Company's (or any of its
Subsidiaries') employees pursuant to any management equity subscription
agreement or stock option agreement in effect as of the date of the Indenture;
provided that the aggregate price paid for all such repurchased, redeemed,
acquired or retired Equity Interests shall not exceed $1.5 million in any
twelve-month period (plus the aggregate cash proceeds received by the Company
during such twelve-month period from any issuance of Equity Interests by the
Company to any Principal and to employees of the Company and its Subsidiaries);
and provided further that no Default or Event of Default shall have occurred
and be continuing immediately after such transaction; (5) the redemption of the
JEDI Preferred Stock, at a redemption price equal to the liquidation preference
thereof plus accrued dividends thereon to the date of redemption, in each case
calculated in accordance with the provisions thereof as the same are in effect
on the date of the Indenture, with the net proceeds from the sale of the Equity
Interests in or all or substantially all of the assets of Taurus in accordance
with the covenant described under the caption "--Repurchase at the Option of
Holders--Asset Sales"; (6) repurchases of Equity Interests deemed to occur upon
exercise of stock options if such Equity Interests represent a portion of the
exercise price of such options; (7) the repayment of all amounts due in respect
of the JEDI Debt; and (8) other Restricted Payments in an aggregate amount not
to exceed $5.0 million.
 
  The amount of all Restricted Payments (other than cash) shall be the fair
market value (as determined by a resolution of the Board of Directors set forth
in an Officers' Certificate delivered to the Trustee, which determination shall
be conclusive evidence of compliance with this provision) on the date of the
Restricted Payment of the asset(s) proposed to be transferred by the Company or
the applicable Restricted Subsidiary, as the case may be, pursuant to the
Restricted Payment. Not later than five days after the date of making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "Restricted
Payments" were computed.
 
                                       81
<PAGE>
 
  The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default; provided
that in no event shall the properties currently operated by Diamond be
transferred to or held by an Unrestricted Subsidiary. For purposes of making
such determination, all outstanding Investments by the Company and its
Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary
so designated will be deemed to be Restricted Payments at the time of such
designation and will reduce the amount available for Restricted Payments under
clause (c) of the first paragraph of this covenant and/or the applicable
provisions of the second paragraph of this covenant, as appropriate. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the greatest of (x) the net book value of such Investments at the time
of such designation, (y) the fair market value of such Investments at the time
of such designation and (z) the original fair market value of such Investments
at the time they were made. Such designation will only be permitted if such
Restricted Payment would be permitted at such time and if such Restricted
Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.
 
 Incurrence of Indebtedness and Issuance of Disqualified Stock
 
  The Indenture will provide that the Company will not, and will not permit any
of its Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or
otherwise, with respect to (collectively, "incur") any Indebtedness (including
Acquired Debt) and that the Company will not issue any Disqualified Stock and
will not permit any of its Subsidiaries to issue any shares of preferred stock;
provided, however, that the Company may incur Indebtedness (including Acquired
Debt) or issue shares of Disqualified Stock if:
 
    (i) the Fixed Charge Coverage Ratio for the Company's most recently ended
  four full fiscal quarters for which internal financial statements are
  available immediately preceding the date on which such additional
  Indebtedness is incurred or such Disqualified Stock is issued would have
  been at least 2.5 to 1, determined on a pro forma basis as set forth in the
  definition of Fixed Charge Coverage Ratio; and
 
    (ii) no Default or Event of Default shall have occurred and be continuing
  at the time such additional Indebtedness is incurred or such Disqualified
  Stock is issued or would occur as a consequence of the incurrence of the
  additional Indebtedness or the issuance of the Disqualified Stock.
 
  Notwithstanding the foregoing, the Indenture will not prohibit any of the
following (collectively, "Permitted Indebtedness"): (a) the Indebtedness
evidenced by the Notes; (b) the incurrence by the Company of Indebtedness
pursuant to Credit Facilities, so long as the aggregate principal amount of all
Indebtedness outstanding under all Credit Facilities does not, at any one time,
exceed the Borrowing Base, provided that if the Company incurs any Indebtedness
pursuant to this clause (b) that would cause the total principal amount of
Indebtedness under this clause (b) to exceed an amount equal to $150.0 million
(less the aggregate amount of all Net Proceeds of Asset Sales including,
without limitation, an Asset Sale involving Taurus, applied to reduce Senior
Debt pursuant to clause (a) of the second paragraph of the covenant described
under the caption "--Repurchase at the Option of Holders--Asset Sales"), the
Fixed Charge Coverage Ratio for the Company's most recently ended four full
fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is
incurred would have been at least 2.0 to 1, determined on a pro forma basis as
set forth in the definition of Fixed Charge Coverage Ratio; (c) the guarantee
by the Guarantors of any Indebtedness that is permitted by the Indenture to be
incurred by the Company; (d) Existing Indebtedness; (e) intercompany
Indebtedness between or among the Company and any of its Wholly Owned
Restricted Subsidiaries; provided, however, that (i) if the Company is the
obligor on such Indebtedness, such Indebtedness is expressly subordinate to the
payment in full of all Obligations with respect to the Notes and (ii)(A) any
subsequent issuance or transfer of Equity Interests that results in any such
Indebtedness being held by a Person other than the Company or a Wholly Owned
Restricted Subsidiary and (B) any sale or other transfer of any such
Indebtedness to a
 
                                       82
<PAGE>
 
Person that is not either the Company or a Wholly Owned Restricted Subsidiary
shall be deemed, in each case, to constitute an incurrence of such Indebtedness
by the Company or such Restricted Subsidiary, as the case may be; (f)
Indebtedness in connection with one or more standby letters of credit,
Guarantees, performance bonds or other reimbursement obligations, in each case,
issued in the ordinary course of business and not in connection with the
borrowing of money or the obtaining of advances or credit (other than advances
or credit on open account, includible in current liabilities, for goods and
services in the ordinary course of business and on terms and conditions which
are customary in the Oil and Gas Business, and other than the extension of
credit represented by such letter of credit, Guarantee or performance bond
itself), not to exceed in the aggregate at any given time 5% of Total Assets;
(g) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness in connection with the acquisition of assets or a new Subsidiary;
provided that such Indebtedness was incurred by the prior owner of such assets
or such Subsidiary prior to such acquisition by the Company or one of its
Restricted Subsidiaries and was not incurred in connection with, or in
contemplation of, such acquisition by the Company or one of its Restricted
Subsidiaries; and provided further that (i) the Fixed Charge Coverage Ratio for
the Company's most recently ended four full fiscal quarters for which internal
financial statements are available immediately preceding the date on which such
additional Indebtedness is incurred would have been at least 2.5 to 1,
determined on a pro forma basis as set forth in the definition of Fixed Charge
Coverage Ratio and (ii) no Default or Event of Default shall have occurred and
be continuing at the time such additional Indebtedness is incurred or would
occur as a consequence of the incurrence of such additional Indebtedness; (h)
Indebtedness under Interest Rate Hedging Agreements entered into for the
purpose of limiting interest rate risks, provided that the obligations under
such agreements are related to payment obligations on Indebtedness otherwise
permitted by the terms of this covenant and that the aggregate notional
principal amount of such agreements does not exceed the principal amount of the
Indebtedness to which such agreements relate; (i) Indebtedness under Oil and
Gas Hedging Contracts, provided that such contracts were entered into in the
ordinary course of business for the purpose of limiting risks that arise in the
ordinary course of business of the Company and its Subsidiaries; (j) the
incurrence by the Company of Indebtedness not otherwise permitted to be
incurred pursuant to this paragraph, provided that the aggregate principal
amount (or accreted value, as applicable) of all Indebtedness incurred pursuant
to this clause (j), together with all Permitted Refinancing Debt incurred
pursuant to clause (k) of this paragraph in respect of Indebtedness previously
incurred pursuant to this clause (j), does not exceed $15.0 million at any one
time outstanding; (k) Permitted Refinancing Debt incurred in exchange for, or
the net proceeds of which are used to refinance, extend, renew, replace,
defease or refund, Indebtedness that was permitted by the Indenture to be
incurred (including Indebtedness previously incurred pursuant to this clause
(k)); (l) accounts payable or other obligations of the Company or any
Subsidiary to trade creditors created or assumed by the Company or such
Subsidiary in the ordinary course of business in connection with the obtaining
of goods or services; (m) Indebtedness consisting of obligations in respect of
purchase price adjustments, guarantees or indemnities in connection with the
acquisition or disposition of assets; (n) the incurrence by the Company's
Unrestricted Subsidiaries of Non-Recourse Debt, provided, however, that if any
such Indebtedness ceases to be Non-Recourse Debt of an Unrestricted Subsidiary,
such event shall be deemed to constitute an incurrence of Indebtedness by a
Restricted Subsidiary of the Company; and (o) production imbalances that do
not, at any one time outstanding, exceed two percent of the Total Assets of the
Company.
 
 No Senior Subordinated Debt
 
  The Indenture will provide that (i) the Company will not incur, create,
issue, assume, guarantee or otherwise become liable for any Indebtedness that
is subordinate or junior in right of payment to any Senior Debt and senior in
any respect in right of payment to the Notes and (ii) no Guarantor will
directly or indirectly incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of
payment to any Guarantees issued in respect of Senior Debt
 
                                       83
<PAGE>
 
and senior in any respect in right of payment to the Subsidiary Guarantees,
provided, however, that the foregoing limitations will not apply to
distinctions between categories of Indebtedness that exist by reason of any
Liens arising or created in respect of some but not all such Indebtedness.
 
 Liens
 
  The Indenture will provide that the Company will not, and will not permit any
of its Subsidiaries to, create, incur, assume or otherwise cause or suffer to
exist or become effective any Lien securing Indebtedness of any kind (other
than Permitted Liens) upon any of its property or assets, now owned or
hereafter acquired.
 
 Sale and Leaseback Transactions
 
  The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, enter into any sale and leaseback
transaction; provided that the Company may enter into a sale and leaseback
transaction if (i) the Company could have (a) incurred Indebtedness in an
amount equal to the Attributable Debt relating to such sale and leaseback
transaction pursuant to the test set forth in the first paragraph of the
covenant described above under the caption "--Incurrence of Additional
Indebtedness and Issuance of Disqualified Stock" and (b) incurred a Lien to
secure such Indebtedness pursuant to the covenant described above under the
caption "--Liens," (ii) the gross cash proceeds of such sale and leaseback
transaction are at least equal to the fair market value (as determined in good
faith by a resolution the Board of Directors set forth in an Officers'
Certificate delivered to the Trustee, which determination shall be conclusive
evidence of compliance with this provision) of the property that is the subject
of such sale and leaseback transaction and (iii) the transfer of assets in such
sale and leaseback transaction is permitted by, and the Company applies the net
proceeds of such transaction in compliance with, the covenant described above
under the caption "--Repurchase at the Option of Holders--Asset Sales."
 
 Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries
 
  The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to (i)(x) pay dividends or make any
other distributions to the Company or any of its Restricted Subsidiaries (1) on
its Capital Stock or (2) with respect to any other interest or participation
in, or measured by, its profits, or (y) pay any indebtedness owed to the
Company or any of its Restricted Subsidiaries, (ii) make loans or advances to
the Company or any of its Restricted Subsidiaries or (iii) transfer any of its
properties or assets to the Company or any of its Restricted Subsidiaries,
except for such encumbrances or restrictions existing under or by reason of (a)
the Credit Agreement as in effect as of the date of the Indenture, and any
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings thereof or any other Credit Facility,
provided that such amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements, refinancings or other Credit
Facilities are no more restrictive with respect to such dividend and other
payment restrictions than those contained in the Credit Agreement as in effect
on the date of the Indenture, (b) the Indenture and the Notes, (c) applicable
law, (d) any instrument governing Indebtedness or Capital Stock of a Person
acquired by the Company or any of its Restricted Subsidiaries as in effect at
the time of such acquisition (except, in the case of Indebtedness, to the
extent such Indebtedness was incurred in connection with or in contemplation of
such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person and
its Subsidiaries, or the property or assets of the Person and its Subsidiaries,
so acquired, provided that, in the case of Indebtedness, such Indebtedness was
permitted by the terms of the Indenture to be incurred, (e) by reason of
customary non-assignment provisions in leases entered into in the ordinary
course of business and consistent with past practices,
 
                                       84
<PAGE>
 
(f) purchase money obligations for property acquired in the ordinary course of
business that impose restrictions of the nature described in clause (iii) above
on the property so acquired, or (g) Permitted Refinancing Debt, provided that
the restrictions contained in the agreements governing such Permitted
Refinancing Debt are no more restrictive than those contained in the agreements
governing the Indebtedness being refinanced.
 
 Merger, Consolidation, or Sale of Assets
 
  The Indenture will provide that the Company may not consolidate or merge with
or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially
all of its properties or assets, in one or more related transactions, to
another Person and the Company may not permit any of its Restricted
Subsidiaries to enter into any such transaction or series of transactions if
such transaction or series of transactions would, in the aggregate, result in a
sale, assignment, transfer, lease, conveyance, or other disposition of all or
substantially all of the properties or assets of the Company to another Person
unless (i) the Company is the surviving corporation or the Person formed by or
surviving any such consolidation or merger (if other than the Company) or to
which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made is a corporation organized or existing under the laws of
the United States, any state thereof or the District of Columbia; (ii) the
Person formed by or surviving any such consolidation or merger (if other than
the Company) or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made assumes all the obligations of the
Company under the Notes and the Indenture pursuant to a supplemental indenture
in a form reasonably satisfactory to the Trustee; (iii) immediately before and
after giving effect to such transaction no Default or Event of Default exists;
and (iv) except in the case of a merger of the Company with or into a Wholly
Owned Subsidiary of the Company, the Company or the Person formed by or
surviving any such consolidation or merger (if other than the Company), or to
which such sale, assignment, transfer, lease, conveyance or other disposition
shall have been made (A) will have Total Assets immediately after the
transaction equal to or greater than the Total Assets of the Company
immediately preceding the transaction and (B) will, at the time of such
transaction and after giving pro forma effect thereto as if such transaction
had occurred at the beginning of the applicable four-quarter period, be
permitted to incur at least $1.00 of additional Indebtedness pursuant to the
test set forth in the first paragraph of the covenant described above under the
caption "--Incurrence of Indebtedness and Issuance of Preferred Stock."
 
 Transactions with Affiliates
 
  The Indenture will provide that the Company will not, and will not permit any
of its Restricted Subsidiaries to, make any payment to, or sell, lease,
transfer or otherwise dispose of any of its properties or assets to, or
purchase any property or assets from, or enter into or make or amend any
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any of its Affiliates (each of the foregoing, an "Affiliate
Transaction"), unless (i) such Affiliate Transaction is on terms that are no
less favorable to the Company or the relevant Restricted Subsidiary than those
that would have been obtained in a comparable transaction by the Company or
such Restricted Subsidiary with an unrelated Person and (ii) the Company
delivers to the Trustee (a) with respect to any Affiliate Transaction or series
of related Affiliate Transactions involving aggregate consideration in excess
of $1.0 million, a resolution of the Board of Directors set forth in an
Officers' Certificate certifying that such Affiliate Transaction complies with
clause (i) above and that such Affiliate Transaction has been approved by a
majority of the members of the Board of Directors who are disinterested with
respect to such Affiliate Transaction, which resolution shall be conclusive
evidence of compliance with this provision, and (b) with respect to any
Affiliate Transaction or series of related Affiliate Transactions involving
aggregate consideration in excess of $5.0 million, an opinion as to the
fairness to the Holders of such Affiliate Transaction from a financial point of
view issued by an accounting, appraisal, engineering or investment banking firm
of national standing; provided that the following shall not be
 
                                       85
<PAGE>
 
deemed Affiliate Transactions: (1) any sale of hydrocarbons or other mineral
products or the entering into or performance of Oil and Gas Hedging Contracts,
gas gathering, transportation or processing contracts or oil or natural gas
marketing or exchange contracts, in each case, in the ordinary course of
business, so long as the terms of any such transaction are approved by a
majority of the members of the Board of Directors who are disinterested with
respect to such transaction as being the most favorable of at least (x) two
bids, quotes or proposals, at least one of which is from a Person that is not
an Affiliate of the Company (in the event that the Company determines in good
faith that it is able to obtain only two bids, quotes or proposals with respect
to such transaction) or (y) three bids, quotes or proposals, at least two of
which are from Persons that are not Affiliates of the Company (in all other
circumstances), (2) the repayment of all amounts due in respect of the JEDI
Debt, (3) the sale to an Affiliate of the Company of Equity Interests in the
Company that do not constitute Disqualified Stock, (4) transactions
contemplated by any employment agreement or other compensation plan or
arrangement entered into by the Company or any of its Restricted Subsidiaries
in the ordinary course of business and consistent with the past practice of the
Company or such Restricted Subsidiary, including those described in this
Prospectus under the caption "Executive Compensation and Other Information--
Employment Agreements," (5) transactions between or among the Company and/or
its Restricted Subsidiaries, (6) Restricted Payments and Permitted Investments
that are permitted by the provisions of the Indenture described above under the
caption "--Restricted Payments," (7) the transactions described in this
Prospectus under the caption "Certain Transactions" and (8) the payment of
dividends on, or the redemption of, the JEDI Preferred Stock, in either case,
to the extent otherwise permitted by the Indenture.
 
 Additional Subsidiary Guarantees
 
  The Indenture will provide that if the Company or any of its Subsidiaries
shall acquire or create another Subsidiary after the date of the Indenture,
then such newly acquired or created Subsidiary will be required to execute a
Subsidiary Guarantee and deliver an opinion of counsel, in accordance with the
terms of the Indenture, provided that the foregoing requirement shall not apply
to any newly acquired or created Subsidiary that has been properly designated
as an Unrestricted Subsidiary in accordance with the Indenture for so long as
it continues to constitute an Unrestricted Subsidiary.
 
 Business Activities
 
  The Company and the Guarantors will not, and will not permit any Restricted
Subsidiary to, engage in any material respect in any business other than the
Oil and Gas Business.
 
 Reports
 
  Pursuant to Section 15(d) of the Exchange Act, upon effectiveness of the
Registration Statement, the Company and the Guarantors will be required to file
with the Commission reports on Form 10-K, Form 10-Q and Form 8-K for the
remainder of 1996, at a minimum. In addition, the Company and the Guarantors
have covenanted to file with the Commission, to the extent such filings are
accepted by the Commission and whether or not the Company has a class of
securities registered under the Exchange Act, the annual reports, quarterly
reports and other documents that the Company and the Guarantors would be
required to file if the Company were subject to Section 13 or 15 of the
Exchange Act, in each case on or before the dates on which such reports and
other documents would have been required to have been filed with the Commission
if the Company had been subject to Section 13 or 15 of the Exchange Act
beginning with the Company's fiscal quarter ended March 31, 1996. The Company
will also be required (a) to file with the Trustee (with exhibits), and provide
to each Holder of Notes (without exhibits), without cost to such Holder, copies
of such reports and documents within 15 days after the date on which the
Company files such reports and documents with the Commission or the date on
which the Company would be required to file such reports and documents if the
Company were so required and (b) if filing such reports and documents with the
Commission is not accepted by
 
                                       86
<PAGE>
 
the Commission or is prohibited under the Exchange Act, to supply at the
Company's cost copies of such reports and documents (including any exhibits
thereto) to any Holder of Notes promptly upon written request. In addition, the
Company and the Guarantors have agreed that, for so long as any Notes remain
outstanding, they will furnish to the Holders and to prospective investors,
upon their request, the information required to be delivered pursuant to Rule
144A(d)(4) under the Securities Act.
 
EVENTS OF DEFAULT AND REMEDIES
 
  The Indenture will provide that each of the following constitutes an Event of
Default: (i) default for 30 days in the payment when due of interest on the
Notes (whether or not prohibited by the subordination provisions of the
Indenture); (ii) default in payment when due of the principal of or premium, if
any, on the Notes (whether or not prohibited by the subordination provisions of
the Indenture); (iii) failure by the Company for 30 days after notice from the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding to comply with the provisions described under the
captions "--Repurchase at the Option of Holders--Change of Control," "--
Repurchase at the Option of Holders--Asset Sales," "--Certain Covenants--
Restricted Payments," "--Certain Covenants--Incurrence of Indebtedness and
Issuance of Preferred Stock" or "--Certain Covenants--Merger, Consolidation, or
Sale of Assets"; (iv) failure by the Company for 60 days after notice from the
Trustee or the Holders of at least 25% in aggregate principal amount of the
Notes then outstanding to comply with any of its other agreements in the
Indenture or the Notes; (v) except as permitted by the Indenture, any
Subsidiary Guarantee of a Significant Subsidiary shall be held in any judicial
proceeding to be unenforceable or invalid or shall cease for any reason to be
in full force and effect or any Guarantor that is a Significant Subsidiary, or
any Person acting on behalf of any such Guarantor, shall deny or disaffirm its
obligations under its Subsidiary Guarantee; (vi) default under any mortgage,
indenture or instrument under which there may be issued or by which there may
be secured or evidenced any Indebtedness for money borrowed by the Company or
any of its Restricted Subsidiaries (or the payment of which is guaranteed by
the Company or any of its Restricted Subsidiaries) whether such Indebtedness or
Guarantee now exists, or is created after the date of the Indenture, which
default (a) is caused by a failure to pay principal of or premium, if any, or
interest on such Indebtedness prior to the expiration of the grace period
provided in such Indebtedness on the date of such default (a "Payment Default")
or (b) results in the acceleration of such Indebtedness prior to its express
maturity and, in each case, the principal amount of any such Indebtedness,
together with the principal amount of any other such Indebtedness under which
there is then existing a Payment Default or the maturity of which has been so
accelerated, aggregates $10.0 million or more; (vii) failure by the Company or
any of its Restricted Subsidiaries to pay final, non-appealable judgments
aggregating in excess of $5.0 million, which judgments remain unpaid or
undischarged for a period of 60 days; and (viii) certain events of bankruptcy
or insolvency with respect to the Company or any of its Restricted Subsidiaries
that constitute a Significant Subsidiary or any group of Restricted
Subsidiaries that, taken together, would constitute a Significant Subsidiary.
 
  If any Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the then outstanding Notes may declare
all the Notes to be due and payable immediately. Notwithstanding the foregoing,
in the case of an Event of Default arising from certain events of bankruptcy or
insolvency, with respect to the Company, any Restricted Subsidiary that
constitutes a Significant Subsidiary or any group of Restricted Subsidiaries
that, taken together, would constitute a Significant Subsidiary, all
outstanding Notes will become due and payable without further action or notice.
Holders of the Notes may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a
majority in principal amount of the then outstanding Notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
Holders of the Notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal or
interest) if it determines that withholding notice is in their interest.
 
                                       87
<PAGE>
 
  In the case of any Event of Default occurring by reason of any willful action
(or inaction) taken (or not taken) by or on behalf of the Company with the
intention of avoiding payment of the premium that the Company would have had to
pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to
April 1, 2001 by reason of any willful action (or inaction) taken (or not
taken) by or on behalf of the Company with the intention of avoiding the
prohibition on redemption of the Notes prior to April 1, 2001, then the premium
specified in the Indenture shall also become immediately due and payable to the
extent permitted by law upon the acceleration of the Notes.
 
  The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest, premium or Liquidated Damages, if any, on, or the principal of, the
Notes.
 
  The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required, within
five business days of becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
  No director, officer, employee, incorporator or stockholder of the Company,
as such, shall have any liability for any obligations of the Company under the
Notes or the Indenture or for any claim based on, in respect of, or by reason
of, such obligations or their creation. Each Holder of Notes, by accepting a
Note, waives and releases all such liability. The waiver and release are part
of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.
 
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
  The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance") except for (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, interest and
Liquidated Damages, if any, on such Notes when such payments are due from the
trust referred to below, (ii) the Company's obligations with respect to the
Notes concerning issuing temporary Notes, registration of Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for
payment and money for security payments held in trust, (iii) the rights,
powers, trusts, duties and immunities of the Trustee, and the Company's
obligations in connection therewith 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 ("Covenant Defeasance") and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events) described under "Events of
Default" 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 or the Guarantors must irrevocably deposit with the Trustee, in trust,
for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable
Government Securities, 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, premium, if any, interest and
Liquidated Damages, if any, on the outstanding Notes on the stated maturity or
on the applicable redemption date, as the case may be,
 
                                       88
<PAGE>
 
and the Company or the Guarantors must specify whether the Notes are being
defeased to maturity or to a particular redemption date; (ii) in the case of
Legal Defeasance, the Company or the Guarantors shall have delivered to the
Trustee an opinion of counsel in the United States reasonably acceptable to the
Trustee confirming that (A) the Company or the Guarantors has received from, or
there has been published by, the Internal Revenue Service a ruling or (B) since
the date of the Indenture, there has been a change in the applicable federal
income tax law, in either case to the effect that, and based thereon such
opinion of counsel shall confirm 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 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 had not occurred; (iii) in the case of
Covenant Defeasance, the Company or the Guarantors shall have delivered to the
Trustee an opinion of counsel in the United States reasonably acceptable to the
Trustee confirming that the Holders of the outstanding Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such
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 Covenant Defeasance had not occurred; (iv) no Default or Event of
Default shall have occurred and be continuing on the date of such deposit
(other than a Default or Event of Default resulting from the borrowing of funds
to be applied to such deposit) or insofar as Events of Default from bankruptcy
or insolvency events are concerned, at any time in the period ending on the
91st day after the date of deposit; (v) such Legal Defeasance or Covenant
Defeasance will not result in a breach or violation of, or constitute a default
under any material agreement or instrument (other than the Indenture) to which
the Company or any of its Restricted Subsidiaries is a party or by which the
Company or any of its Restricted Subsidiaries is bound; (vi) the Company or the
Guarantors must have delivered to the Trustee an opinion of counsel to the
effect that after the 91st day following the deposit, the trust funds will not
be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally; (vii) the
Company or the Guarantors must deliver to the Trustee an Officers' Certificate
stating that the deposit was not made by the Company or the Guarantors, as
applicable, with the intent of preferring the Holders of Notes over the other
creditors of the Company or the Guarantors, as applicable, with the intent of
defeating, hindering, delaying or defrauding creditors of the Company or the
Guarantors, as applicable, or others; and (viii) the Company must deliver to
the Trustee an Officers' Certificate and an opinion of counsel, each stating
that all conditions precedent provided for relating to the Legal Defeasance or
the Covenant Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
  A Holder may transfer or exchange Notes in accordance with the Indenture. The
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.
The Company is not required to transfer or exchange any Note selected for
redemption. Also, the Company is not required to transfer or exchange any Note
for a period of 15 days before a selection of Notes to be redeemed.
 
  The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
  Except as provided in the next two succeeding paragraphs, the Indenture or
the Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Notes), and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a tender
offer or exchange offer for Notes).
 
                                       89

  Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of Notes whose Holders must consent to an amendment,
supplement or waiver, (ii) reduce the principal of or change the fixed maturity
of any Note or alter the provisions with respect to the redemption of the Notes
(other than provisions relating to the covenants described above under the
caption "--Repurchase at the Option of Holders"), (iii) reduce the rate of or
change the time for payment of interest or Liquidated Damages on any Note, (iv)
waive a Default or Event of Default in the payment of principal of or premium,
if any, or interest or Liquidated Damages, if any, on the Notes (except a
rescission of acceleration of the Notes by the Holders of at least a majority
in aggregate principal amount of the Notes and a waiver of the payment default
that resulted from such acceleration), (v) make any Note payable in money other
than that stated in the Notes, (vi) make any change in the provisions of the
Indenture relating to waivers of past Defaults or the rights of Holders of
Notes to receive payments of principal of or premium, if any, or interest or
Liquidated Damages, if any, on the Notes, (vii) waive a redemption payment with
respect to any Note (other than a payment required by one of the covenants
described above under the caption "--Repurchase at the Option of Holders") or
(viii) make any change in the foregoing amendment and waiver provisions.
Without the consent of at least 66 2/3% in aggregate principal amount of the
Notes then outstanding (including consents obtained in connection with a
purchase of, or tender offer or exchange offer for, Notes), no waiver or
amendment to the Indenture may make any change in the provisions described
above under the captions "--Repurchase at the Option of Holders--Change of
Control" and "--Repurchase at the Option of Holders--Assets Sales" that
adversely affect the rights of any Holder of Notes. In addition, any amendment
to the provisions of Article 10 of the Indenture (which relate to
subordination) will require the consent of the Holders of at least 66 2/3% in
aggregate principal amount of the Notes then outstanding if such amendment
would adversely affect the rights of Holders of Notes.
 
  Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture or the Notes
to cure any ambiguity, defect or inconsistency, to provide for uncertificated
Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company's obligations to Holders of Notes in the case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the Holders of Notes or that does not adversely affect
the legal rights under the Indenture of any such Holder, or to comply with
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the Trust Indenture Act.
 
CONCERNING THE TRUSTEE
 
  The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any
such claim as security or otherwise. The Trustee will be permitted to engage in
other transactions; however, if it acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue or resign. The Trustee is a lender to the Company under the Credit
Agreement and is an affiliate of Chemical Securities Inc. See "Description of
Other Indebtedness--Credit Agreement" and "Offer and Resale."
 
  The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the
conduct of his own affairs. Subject to such provisions, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request of any Holder of Notes, unless such Holder shall have offered to
the Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

BOOK-ENTRY, DELIVERY AND FORM
 
  The Notes to be issued as set forth herein will initially be issued in the
form of one or more permanent global certificates in definitive, fully-
registered form ("Global Note"). Each Global Note will be deposited on the date
of the closing of the exchange of the Private Notes for the Exchange Notes
offered hereby (the "Closing Date") with, or on behalf of, DTC and registered
in the name of Cede & Co., as nominee of the Depositary (such nominee being
referred to herein as the "Global Note Holder").
 
  The Depositary is a limited-purpose trust company that was created to hold
securities for its participating organizations (collectively, the
"Participants" or the "Depositary's Participants") and to facilitate the
clearance and settlement of transactions in such securities between
Participants through electronic book-entry changes in accounts of its
Participants. The Depositary's Participants include securities brokers and
dealers (including the Initial Purchasers), banks and trust companies, clearing
corporations and certain other organizations. Access to the Depositary's system
is also available to other entities such as banks, brokers, dealers and trust
companies (collectively, the "Indirect Participants" or the "Depositary's
Indirect Participants") that clear through or maintain a custodial relationship
with a Participant, either directly or indirectly. Persons who are not
Participants may beneficially own securities held by or on behalf of the
Depositary only thorough the Depositary's Participants or the Depositary's
Indirect Participants.
 
  The Company expects that pursuant to procedures established by the Depositary
(i) upon deposit of the Global Note, the Depositary will credit the accounts of
Participants designated by the Initial Purchasers with portions of the
principal amount of the Global Note and (ii) ownership of the Notes evidenced
by the Global Note will be shown on, and the transfer of ownership thereof will
be effected only through, records maintained by the Depositary (with respect to
the interests of the Depositary's Participants), the Depositary's Participants
and the Depositary's Indirect Participants. Prospective purchasers are advised
that the laws of some states require that certain persons take physical
delivery in definitive form of securities that they own. Consequently, the
ability to transfer Notes evidenced by the Global Note will be limited to such
extent.
 
  So long as the Global Note Holder is the registered owner of any Notes, the
Global Note Holder will be considered the sole Holder under the Indenture of
any Notes evidenced by the Global Note. Beneficial owners of Notes evidenced by
the Global Note will not be considered the owners or Holders thereof under the
Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any
aspect of the records of the Depositary or for maintaining, supervising or
reviewing any records of the Depositary relating to the Notes.
 
  Payments in respect of the principal of, premium, if any, and interest on any
Notes registered in the name of the Global Note Holder on the applicable record
date will be payable by the Trustee to or at the direction of the Global Note
Holder in its capacity as the registered Holder under the Indenture. Under the
terms of the Indenture, the Company and the Trustee may treat the persons in
whose names Notes, including the Global Note, are registered as the owners
thereof for the purpose of receiving such payments. Consequently, neither the
Company nor the Trustee has or will have any responsibility or liability for
the payment of such amounts to beneficial owners of Notes. The Company
believes, however, that it is currently the policy of the Depositary to
immediately credit the accounts of the relevant Participants with such
payments, in amounts proportionate to their respective holdings of beneficial
interests in the relevant security as shown on the records of the Depositary.
Payments by the Depositary's Participants and the Depositary's Indirect
Participants to the beneficial owners of Notes will be governed by standing
instructions and customary practice and will be the responsibility of the
Depositary's Participants or the Depositary's Indirect Participants.
 
                                       91
<PAGE>
 
  DTC has advised the Company that neither DTC nor Cede & Co. will consent or
vote with respect to the Notes. Under its usual procedures, DTC mails an
omnibus proxy to the issuer as soon as possible after the record date. The
omnibus proxy assigns Cede & Co.'s consenting or voting rights to those
Participants to whose accounts the Notes are credited on the record date
(identified in a listing attached to the omnibus proxy).
 
  DTC may discontinue providing its services as securities depository with
respect to the Notes at any time. Neither the Company, the Trustee nor any
registrar or paying agent will have any responsibility for the performance by
DTC or its Participants or Indirect Participants of their respective
obligations under the rules and procedures governing their operations. The
information in this section concerning DTC and DTC's book-entry system has been
obtained from sources that the Company believes to be reliable, but the Company
takes no responsibility for the accuracy thereof.
 
 Certificated Securities
 
  Subject to certain conditions, any person having a beneficial interest in the
Global Note may, upon request to the Trustee, exchange such beneficial interest
for Notes in the form of Certificated Securities. Upon any such issuance, the
Trustee is required to register such Certificated Securities in the name of,
and cause the same to be delivered to, such person or persons (or the nominee
of any thereof). In addition, if (i) the Depositary notifies the Company that
the Depositary is no longer willing or able to act as a depositary and the
Company is unable to locate a qualified successor within 90 days or (ii) the
Company, at its option, notifies the Trustee in writing that it elects to cause
the issuance of Notes in the form of Certificated Securities under the
Indenture, then, upon surrender by the Global Note Holder of its Global Note,
Notes in such form will be issued to each person that the Global Note Holder
and the Depositary identify as being the beneficial owner of the related Notes.
 
  Neither the Company nor the Trustee will be liable for any delay by the
Global Note Holder or the Depositary in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from the Global Note Holder or the
Depositary for all purposes.
 
 Same-Day Settlement and Payment
 
  The Indenture will require that payments in respect of the Notes represented
by the Global Note (including principal, premium, if any, and interest) be made
by wire transfer of immediately available funds to the accounts specified by
the Global Note Holder. With respect to Certificated Securities, the Company
will make all payments of principal, premium, if any, and interest, by wire
transfer of immediately available funds to the accounts specified by the
Holders thereof that hold at least $5.0 million in aggregate principal amount
of the Notes or, if no such account is specified or if a Holder holds less than
$5.0 million in aggregate principal amount of the Notes, by mailing a check to
each such Holder's registered address. The Notes represented by the Global Note
are expected to be eligible to trade in the Depositary's Same-Day Funds
Settlement System, and any permitted secondary market trading activity in such
Notes will, therefore, be required by the Depositary to be settled in
immediately available funds.

preferred stock subsequent to the commencement of the period for which the
Fixed Charge Coverage Ratio is being calculated but prior to the date on which

CREDIT AGREEMENT
 
  On February 14, 1996, the Company entered into the Credit Agreement with
NationsBank, as lender and as agent, and additional lenders named therein. The
Credit Agreement is guaranteed by all of the Company's subsidiaries and
provides for a revolving credit facility in the amount of $250.0 million. The
current borrowing base is $115.0 million and is subject to redetermination: (i)
semi-annually, (ii) upon the sale of Taurus and (iii) upon issuance of public
subordinated debt in an amount greater than $100.0 million. The lenders under
the Credit Agreement have agreed to waive their right to redetermine the
borrowing base with respect to the issuance of the Notes. At March 31, 1996,
$80.0 million was outstanding under the Credit Agreement and $35.0 million was
available for borrowing thereunder. See "Use of Proceeds."
 
  The Credit Agreement is unsecured. The Company has provided the lenders with
first lien deeds of trust on its oil and natural gas assets which will not
become effective, and the lenders have agreed not to file, unless (i) 80% of
any outstanding borrowings in excess of the borrowing limit is not repaid
within a 90 day period, (ii) cash collateral securing a hedge transaction
exceeds 20% of the borrowing limit or (iii) an event of default or a material
adverse event, as defined in the Credit Agreement, occurs.
 
  So long as no default (as defined in the Credit Agreement) is continuing, the
Company has the option of having all or any portion of the amount borrowed
under the Credit Agreement be the subject of one of the following interest
rates: (i) NationsBank's prime rate, (ii) the CD Rate plus 1 1/4% to 1 5/8%
based upon the ratio of outstanding debt to the available borrowing base and
(iii) LIBOR plus 1 1/4% to 1 5/8% based upon the ratio of outstanding debt to
the available borrowing base. The Company must also pay a commitment fee of
between 0.375% to 0.425% on the unused portion of the credit facility. The
Credit Agreement contains various restrictive covenants, including limitations
on the granting of liens, restrictions on the issuance of additional debt,
restrictions on investments, a requirement to maintain positive working
capital, and restrictions on dividends and stock repurchases. The Credit
Agreement also contains requirements that JEDI, Enron, CalPERS or any wholly
owned subsidiary of either Enron or CalPERS must continue to own a majority of
the outstanding equity of the Company and must have the ability to elect the
majority of the Board of Directors and that certain members of management
maintain specified levels of equity ownership in the Company and continue their
employment with the Company. The Credit Agreement matures on February 16, 2001.

                     DESCRIPTION OF CAPITAL STOCK OF CODA
 
COMMON STOCK
 
  The authorized common stock of Coda aggregates 1,000,000 shares, par value
$0.01 per share. As of May 1, 1996, 913,611 shares of common stock were
outstanding. The holders of shares of common stock possess full voting power
for the election of directors and for all other purposes, each holder of
common stock being entitled to one vote for each share of common stock held of
record by such holder. The shares of common stock do not have cumulative
voting rights. Holders of a majority of the shares of common stock represented
at a meeting at which a quorum is present may currently approve most actions
submitted to the stockholders except for certain corporate actions (e.g.,
mergers, sale of assets and charter amendments), which require the approval of
holders of a majority of the total outstanding shares of common stock. Coda
has never paid dividends on its common stock.
 
  Subject to the rights of holders of any outstanding shares of Preferred
Stock, dividends may be paid on the common stock as and when declared by
Coda's Board of Directors out of any funds of Coda legally available for the
payment thereof. Holders of common stock have no subscription, redemption,
sinking fund, conversion or preemptive rights, except for certain put and call
rights described in "Certain Transactions." The outstanding shares of common
stock are fully paid and nonassessable. After payment is made in full to the
holders of any outstanding shares of Preferred Stock in the event of any
liquidation, dissolution or winding up of the affairs of Coda, the remaining
assets and funds of Coda will be distributed to the holders of common stock
according to their respective shares. The common stock is held by 16 holders
of record. There is no established trading market for the common stock.
 
PREFERRED STOCK
 
  Under Coda's Restated Certificate of Incorporation, the Board of Directors
is authorized to issue up to 40,000 shares of preferred stock, par value $0.01
per share. All 40,000 shares of preferred stock are designated as "15%
Cumulative Preferred Stock." The holders of each share of Preferred Stock are
entitled to receive, when and as declared by the Board of Directors,
cumulative preferential dividends, at the rate of $150.00 per share per annum.
There are currently 20,000 shares of Preferred Stock issued and outstanding.
Shares of Preferred Stock in excess of such 20,000 shares shall be issuable
only for the purpose of paying dividends on the Preferred Stock.
 
  As long as any shares of Preferred Stock are outstanding, no dividends
whatsoever, whether paid in cash, stock or otherwise (except for dividends
paid in shares of common stock, either in the form of a stock split or stock
dividend), may be paid or declared, nor may any distribution be made, on any
common stock to the holders of such stock, unless certain conditions are met.
 
  Coda's Restated Certificate of Incorporation requires that Coda redeem all
the issued and outstanding shares of Preferred Stock at a redemption price of
$1,000 per share, plus all accrued and unpaid dividends (including undeclared
dividends) to the date of redemption, if Coda has sufficient funds legally
available for such redemption and if such redemption would not violate or
conflict with any loan agreement, credit agreement, note agreement, indenture
or other agreement relating to indebtedness to which Coda is a party, on or
before the fifth business day after the earliest to occur of the following:
(i) the closing of the sale by Coda of Taurus and (ii) a Trigger Event, as
such term is defined in the Stockholders Agreement. The Preferred Stock may be
redeemed by Coda at its option, as a whole or in part, to the extent Coda
shall have funds legally available for such redemption, at any time or from
time to time at a redemption price of $1,000 per share, plus all accrued and
unpaid dividends (including undeclared dividends) to the date of redemption.
Such redemption, whether required or optional, is restricted by the Credit
Agreement and the Indenture.
 
 
                                      105
<PAGE>
 
  Upon the complete liquidation, dissolution, or winding up of Coda, whether
voluntarily or involuntarily, the holders of Preferred Stock shall be
entitled, after payment or provision for payment of the debts and other
liabilities of Coda but before any distribution is made to the holders of any
common stock, to be paid $1,000 per share plus all accrued and unpaid
dividends (including undeclared dividends), and shall not be entitled to any
further payment.
 
  Except as otherwise provided herein or required by law, the holders of
shares of Preferred Stock shall not be entitled to vote on any matters to be
voted on by the stockholders of Coda; provided, however, that so long as any
shares of the Preferred Stock are outstanding, Coda shall not, without the
written consent or the affirmative vote of holders of at least a majority of
the total number of shares of Preferred Stock then outstanding and voting as a
class, (i) amend its Certificate of Incorporation or Bylaws or (ii) authorize
the merger (whether or not Coda is a surviving corporation in such merger) of
Coda, in each case, if such amendment or merger would alter, change or abolish
the powers, preference or rights of the Preferred Stock so as to affect the
holders of the Preferred Stock adversely.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
  In the opinion of Haynes and Boone, LLP, counsel to the Company, the
following discussion describes the material federal income tax consequences
expected to result to holders whose Private Notes are exchanged for Exchange
Notes in the Exchange Offer. Such opinion is based upon current provisions of
the Internal Revenue Code of 1986, as amended (the "Code"), applicable
Treasury regulations, judicial authority and administrative rulings and
practice. There can be no assurance that the Internal Revenue Service (the
"Service") will not take a contrary view, and no ruling from the Service has
been or will be sought with respect to the Exchange Offer. Legislative,
judicial or administrative changes or interpretations may be forthcoming that
could alter or modify the statements and conclusions set forth herein. Any
such changes or interpretations may or may not be retroactive and could affect
the tax consequences to holders. Certain holders (including insurance
companies, tax-exempt organizations, financial institutions, broker-dealers,
foreign corporations and persons who are not citizens or residents of the
United States) may be subject to special rules not discussed below. EACH
HOLDER OF PRIVATE NOTES SHOULD CONSULT ITS OWN TAX ADVISOR AS TO THE
PARTICULAR TAX CONSEQUENCES OF EXCHANGING PRIVATE NOTES FOR EXCHANGE NOTES,
INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN LAWS.
 
  The exchange of Private Notes for Exchange Notes will be treated as a "non-
event" for federal income tax purposes because the Exchange Notes will not be
considered to differ materially in kind or extent from the Private Notes. As a
result, no material federal income tax consequences will result to holders
exchanging Private Notes for Exchange Notes.
 
                             PLAN OF DISTRIBUTION
 
  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. This Prospectus, as it may
be amended or supplemented from time to time, may be used by a broker-dealer
in connection with the resales of Exchange Notes received in exchange for
Private Notes where such Private Notes were acquired as a result of market-
making activities or other trading activities. The Company has agreed that for
a period of up to one year after the effective date of the Registration
Statement, it will make this Prospectus, as amended or supplemented, available
to any broker-dealer that requests such document in the Letter of Transmittal
for use in connection with any such resale.
 
 
                                      106
<PAGE>
 
  The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers or any other persons. 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 on 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, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.
 
  The Company has agreed to pay all expenses incident to the Company's
performance of, or compliance with, the Registration Rights Agreement and will
indemnify the holders of Private Notes (including any broker-dealers), and
certain parties related to such holders, against certain liabilities,
including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
  Certain legal matters related to the Exchange Notes offered hereby are being
passed upon for the Company by Mr. Joe Callaway, Vice President and General
Counsel of the Company, and by Haynes and Boone, LLP, Dallas, Texas. Mr.
Callaway currently holds 475 shares, and options to purchase 475 shares, of
Coda common stock.

                                   GLOSSARY
 
  The terms defined in this glossary are used throughout this Prospectus.
 
  "AVERAGE NYMEX PRICE." The average of the NYMEX closing prices for the near
month.
 
  BBL. One stock tank barrel, or 42 U.S. gallons liquid volume, used herein in
reference to crude oil or other liquid hydrocarbons.
 
  BCF. One billion cubic feet of natural gas.
 
  "BEHIND THE PIPE." Hydrocarbons in a potentially producing horizon
penetrated by a well bore the production of which has been postponed pending
the production of hydrocarbons from another formation penetrated by the well
bore. These hydrocarbons are classified as proved but non-producing reserves.
 
  BOE. Barrels of oil equivalent (converting six Mcf of natural gas to one Bbl
of oil).
 
  "DEVELOPMENT WELL." A well drilled within the proven boundaries of an oil or
natural gas reservoir with the intention of completing the stratigraphic
horizon known to be productive.
 
  "GROSS WELLS." The total number of wells in which a working interest is
owned.
 
  "INFILL WELL." A well drilled between known producing wells to better
exploit the reservoir.
 
  MBBLS. One thousand barrels of crude oil or other liquid hydrocarbons.
 
  MBOE. One thousand barrels of oil equivalent.
 
  MMBTU. One million British thermal units.
 
  MCF. One thousand cubic feet of natural gas.
 
  M GALLONS. One thousand U.S. gallons liquid volume, used herein in reference
to natural gas liquids.
 
  MMBBLS. One million barrels of crude oil or other liquid hydrocarbons.
 
  MMBOE. One million barrels of oil equivalent.

  NYMEX. New York Mercantile Exchange.
 
  "PRESENT VALUE OF ESTIMATED FUTURE NET REVENUES." The present value of
estimated future net revenues is an estimate of future net revenues from a
property at its acquisition date, at December 31, 1995, or as otherwise
indicated, after deducting production and ad valorem taxes, future capital
costs and operating expenses, but before deducting federal income taxes. The
future net revenues have been discounted at an annual rate of 10% to determine
their "present value." The present value is shown to indicate the effect of
time on the value of the revenue stream and should not be construed as being
the fair market value of the properties. Estimates have been made using
constant oil and natural gas prices and operating costs at the acquisition
date, at December 31, 1995, or as otherwise indicated. The Company believes
that the present value of estimated future net revenues before
 
                                      109
<PAGE>
 
income taxes, while not in accordance with generally accepted accounting
principles, is an important financial measure used by investors in independent
oil and natural gas producers for evaluating the relative significance of oil
and natural gas properties and acquisitions. The present value of estimated
future net revenues should not be construed as an alternative to the
Standardized Measure, as determined in accordance with generally accepted
accounting principles.
 
  "PRODUCING WELL," "PRODUCTION WELL" OR "PRODUCTIVE WELL." A well that is
producing oil or natural gas or that is capable of production.
 
  "PROVED DEVELOPED RESERVES." Proved developed reserves are those quantities
of crude oil, natural gas and natural gas liquids that, upon analysis of
geological and engineering data, are expected with reasonable certainty to be
recoverable in the future from known oil and natural gas reservoirs under
existing economic and operating conditions. This classification includes: (a)
proved developed producing reserves, which are those expected to be recovered
from currently producing zones under continuation of present operating
methods; and (b) proved developed non-producing reserves, which consist of (i)
reserves from wells that have been completed and tested but are not yet
producing due to lack of market or minor completion problems that are expected
to be corrected, and (ii) reserves currently behind the pipe in existing wells
which are expected to be productive due to both the well log characteristics
and analogous production in the immediate vicinity of the well.
 
  "PROVED RESERVES." The estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions.
 
  "PROVED UNDEVELOPED RESERVES." Proved reserves that may be expected to be
recovered from existing wells that will require a relatively major expenditure
to develop or from undrilled acreage adjacent to productive units that are
reasonably certain of production when drilled.
 
  "ROYALTY INTEREST." An interest in an oil and natural gas property entitling
the owner to a share of oil and natural gas production free of costs of
production.
 
  "STANDARDIZED MEASURE." The standardized measure of discounted net cash
flows related to the Company's proved oil, natural gas and natural gas liquids
reserves net of future production and development costs and future income
taxes calculated in accordance with generally accepted accounting principles.
The calculation is based on a valuation of proved reserves using discounted
cash flows based on year-end prices, costs and economic conditions and a 10%
discount rate.
 
  "WORKING INTEREST." The operating interest that gives the owner the right to
drill, produce and conduct operating activities on the property and to a share
of production, subject to all royalties, overriding royalties and other
burdens and to all costs of exploration, development and operations and all
risks in connection therewith.

                      CODA ENERGY, INC. AND SUBSIDIARIES
 
                   PRO FORMA CONDENSED FINANCIAL STATEMENTS
 
  The accompanying unaudited pro forma condensed statements of operations of
Coda Energy, Inc. (the "Company") for the year ended December 31, 1995 and the
three months ended March 31, 1996, have been prepared as if the acquisition of
the Snyder Properties, the Merger, the sale of the Private Notes and the
Exchange Offer (each as more fully described in the notes to pro forma
condensed financial statements) had occurred on January 1, 1995. Because the
Exchange Notes are being issued under the same financial terms and conditions
as the Private Notes, the Exchange Offer has no impact on the pro forma data.
 
  The historical financial information for the Company was obtained from the
historical consolidated financial statements of the Company contained
elsewhere in this document. The historical financial information of the Snyder
Properties was obtained from internal reports prepared by the seller and is
unaudited. The unaudited pro forma condensed financial statements do not
purport to represent the results of operations which would have occurred had
such transactions been consummated on the dates indicated or the results of
operation for any future date or period. These unaudited pro forma condensed
financial statements should be read in conjunction with the historical
financial statements of the Company.

NOTE A--PRO FORMA ADJUSTMENTS FOR THE MERGER, THE SALE OF THE PRIVATE NOTES
AND THE EXCHANGE OFFER
 
  On February 16, 1996, pursuant to an Agreement and Plan of Merger dated as
of October 30, 1995 (as subsequently amended, the "Merger Agreement") by and
among Coda Energy, Inc. ("Coda"), Joint Energy Development Investments Limited
Partnership ("JEDI"), an affiliate of Enron Capital & Trade Resources Corp.,
and Coda Acquisition, Inc. ("Purchaser"), a subsidiary of JEDI, JEDI acquired
Coda through a merger (the "Merger") at a price of $7.75 per share in cash.
 
  The sources and uses of funds related to the Merger are as follows (in
millions):

                                                                         ======
</TABLE>
 
  Concurrently with the execution of the Merger Agreement, JEDI and Purchaser
entered into certain agreements with members of management of the Company
concerning their employment with and/or equity participation in the Company
after the Merger.
 
  The Merger has been accounted for using the purchase method of accounting.
As such, JEDI's cost of acquiring Coda has been allocated to the assets and
liabilities acquired based on estimated fair values. As a result, the
Company's financial position and operating results subsequent to the date of
the Merger reflect a new basis of accounting and are not comparable to prior
periods.
 
  Following the Merger, the Company issued $110 million principal amount of
Senior Subordinated Notes due 2006 and used $100 million of the proceeds
therefrom to repay all of the subordinated debt owed to JEDI. The remaining
net proceeds together with the reimbursements described below and other
available cash were used to repay approximately $10.0 million in debt
outstanding under the Credit Agreement. ECT Securities Corp. refunded to the
Company $2.0 million in fees paid in connection with the issuance of the JEDI
debt. Further, the Purchasers of the Private Notes reimbursed the Company for
costs and expenses in the amount of $550,000.
 
  The Company is offering to exchange the Exchange Notes for the Private
Notes. The Private Notes were sold in transactions exempt from registration
under the Securities Act on March 18, 1996. The Exchange Offer is intended to
satisfy certain of the Company's obligations under the Registration Rights
Agreement and Purchase Agreement. Because the Exchange Notes are being issued
under the same financial terms and conditions as the Private Notes, the
Exchange Offer has no impact on the pro forma data.

  The accompanying unaudited pro forma condensed statement of operations has
been prepared as if the Merger, the sale of the Private Notes and the Exchange
Offer had occurred on January 1, 1995 and reflects the following adjustments:
 
    (1) To adjust depletion, depreciation, and amortization to reflect JEDI's
  purchase price allocated to property and equipment.
 
    (2) To adjust interest expense to give effect to the net reduction of
  approximately $36.8 million under the Company's credit facility and
  repayment of the note payable to an officer of the Company, partially
  offset by an increase in the interest rate on borrowings under the new
  credit facility of .25%.
 
    (3) To record interest on the Notes at an interest rate of 10 1/2%.
 
    (4) To eliminate stock option compensation expense resulting from the
  Merger.
 
    (5) To eliminate the writedown of oil and gas properties resulting from
  the Merger.
 
    (6) To adjust the provision for income taxes for the change in financial
  taxable income resulting from adjustments (1), (2), (3), (4) and (5).
 
    (7) To record the cumulative dividend requirements of the redeemable
  preferred stock issued to JEDI.
 
NOTE B--PRO FORMA ADJUSTMENTS FOR THE ACQUISITION OF THE SNYDER PROPERTIES
 
  In October 1995, the Company acquired interests in 63 producing oil and gas
properties located in west Texas from Snyder Oil Company (the "Snyder
Properties"). The aggregate purchase price was $17.1 million in cash, of which
$16.0 million was financed by borrowings under the Company's then-existing
credit agreement. The acquisition was accounted for by the purchase method of
accounting. Prior to the acquisition, the Snyder Properties were included in
the consolidated financial statements of the seller and were not accounted for
as a separate entity.
 
  The accompanying unaudited pro forma condensed statement of operations has
been prepared as if the acquisition of the Snyder Properties occurred on
January 1, 1995 and reflects the following adjustments:
 
    (8) To reclassify fees from overhead charges billed to working interest
  owners, which are classified as a reduction of general and administrative
  expenses in the Company's consolidated statements of operations.
 
    (9) To adjust depletion, depreciation and amortization to reflect the
  effect of the acquisition of the Snyder Properties. Depletion, depreciation
  and amortization of oil and gas properties is computed using the unit-of-
  production method.
 
    (10) To adjust interest expense for the estimated amounts the Company
  would have incurred on the incremental borrowings pursuant to the Company's
  credit facility used to acquire the Snyder Properties. The interest rate
  used was based on the interest rate options provided for in the Company's
  credit facility in effect at the time.
 
    (11) To adjust the provision for income taxes for the change in financial
  taxable income resulting from inclusion of the historical results of the
  Snyder Properties and adjustments (9) and (10).

1. THE MERGER
 
  On February 16, 1996, pursuant to an Agreement and Plan of Merger dated as
of October 30, 1995 (as amended, the "Merger Agreement"), by and among Coda
Energy, Inc. ("Coda" or together with its subsidiaries the "Company"), Joint
Energy Development Investments Limited Partnership ("JEDI"), which is an
affiliate of Enron Capital & Trade Resources Corp. ("ECT"), and Coda
Acquisition, Inc. ("CAI"), which was a subsidiary of JEDI, JEDI acquired Coda
through a merger (the "Merger") at a price of $7.75 per share in cash (for an
aggregate purchase price of approximately $176.2 million). Concurrently with
the execution of the Merger Agreement, JEDI and CAI entered into certain
agreements with members of the Company's management (the "Management Group"),
providing for a continuing role of management in the Company after the Merger.
Following consummation of the Merger, the Management Group owns approximately
5% of Coda's common stock on a fully-diluted basis. JEDI owns the remaining
95%.
 
  The sources and uses of funds related to financing the Merger were as
follows:

     (1) Represents indebtedness incurred by CAI and assumed by Coda to
         fund a portion of the consideration paid in the Merger.
 
  The Merger has been accounted for using the purchase method of accounting.
As such, JEDI's cost of acquiring Coda has been allocated to the assets and
liabilities acquired based on estimated fair values. As a result, the
Company's financial position and operating results subsequent to the date of
the Merger reflect a new basis of accounting and are not comparable to prior
periods.
 
  The allocation of JEDI's purchase price to the assets and liabilities of
Coda resulted in a significant increase in the carrying value of the Company's
oil and gas properties. Under the full cost method of accounting, the carrying
value of oil and gas properties (net of related deferred taxes) is generally
not permitted to exceed the sum of the present value (10% discount rate) of
estimated future net cash flows (after tax) from proved reserves, based on
current prices and costs, plus the lower of cost or estimated fair value of
unproved properties (the "cost center ceiling"). Based upon the allocation of
JEDI's purchase price and estimated proved reserves and product prices in
effect at the date of the

                      CODA ENERGY, INC. AND SUBSIDIARIES
 
       NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
Merger, the purchase price allocated to oil and gas properties was in excess
of the cost center ceiling by approximately $83.3 million ($53.3 million net
of related deferred taxes). The resulting writedown is a non-cash charge and
has been included in the results of operations for the period ended March 31,
1996.
 
2. ACCOUNTING AND REPORTING POLICIES
 
  The consolidated financial statements include the accounts of Coda Energy,
Inc., its majority-owned subsidiaries and its pro rata share of the assets,
liabilities and operations of oil and gas partnerships and joint ventures. All
significant intercompany balances and transactions have been eliminated in
consolidation. Certain reclassifications have been made to prior years'
amounts to conform to the current year presentation.
 
  The accompanying consolidated financial statements, which should be read in
conjunction with the audited consolidated financial statements for the year
ended December 31, 1995, reflect all adjustments (consisting only of normal
recurring accruals) which are, in the opinion of management, necessary to
present fairly the financial position as of March 31, 1996, and the results of
operations and cash flows for the periods ended March 31, 1995, February 16,
1996 and March 31, 1996. The results for the period ended March 31, 1996, are
not necessarily indicative of results for a full year.
 
  Fees from overhead charges billed to working interest owners, including the
Company, of $1.2 million, $848,000 and $808,000 for the periods ended March
31, 1995, February 16, 1996 and March 31, 1996, respectively, have been
classified as a reduction of general and administrative expenses in the
accompanying consolidated statements of operations.
 
3. CREDIT AGREEMENT
 
  On February 14, 1996, the Company entered into a credit agreement with
NationsBank of Texas, N.A. ("NationsBank"), as lender and as agent, and
additional lenders named therein (the "Credit Agreement"). The Credit
Agreement is guaranteed by all of the Company's subsidiaries and provides for
a revolving credit facility in an amount up to $250.0 million. The current
borrowing base is $115.0 million and is subject to redetermination: (i)
semiannually, (ii) upon the sale of Taurus and (iii) upon issuance of public
subordinated debt in an amount greater than $100.0 million. The lenders under
the Credit Agreement have agreed to waive their right to redetermine the
borrowing base with respect to the issuance of the Notes. At March 31, 1996,
$80.0 million was outstanding under the Credit Agreement and $35.0 million was
available for borrowing thereunder.
 
  The Credit Agreement is unsecured. The Company has provided the lenders with
first lien deeds of trust on its oil and natural gas assets which will not
become effective, and the lenders have agreed not to file, unless (i) 80% of
any outstanding borrowings in excess of the borrowing base is not repaid
within a 90 day period, (ii) cash collateral securing a hedge transaction
exceeds 20% of the borrowing base or (iii) an event of default or a material
adverse event, as defined in the Credit Agreement, occurs.
 
  So long as no default (as defined in the Credit Agreement) is continuing,
the Company has the option of having all or any portion of the amount borrowed
under the Credit Agreement be the subject of one of the following interest
rates: (i) NationsBank's prime rate, (ii) the CD Rate plus 1 1/4% to 1 5/8%
based upon the ratio of outstanding debt to the available borrowing base and
(iii) LIBOR plus 1 1/4% to 1 5/8% based upon the ratio of outstanding debt to
the available borrowing base. The Company must also pay a commitment fee of
between 0.375% to 0.425% on the unused portion of the credit facility.

                      CODA ENERGY, INC. AND SUBSIDIARIES
 
       NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
The Credit Agreement contains various restrictive covenants, including
limitations on the granting of liens, restrictions on the issuance of
additional debt, restrictions on investments, a requirement to maintain
positive working capital, and restrictions on dividends and stock repurchases.
The Credit Agreement also contains requirements that JEDI, Enron, or certain
affiliates of JEDI must continue to own a majority of the outstanding equity
of the Company and must have the ability to elect the majority of the Board of
Directors and that certain members of management maintain specified levels of
equity ownership in the Company and continue their employment with the
Company. The Credit Agreement matures on February 16, 2001.
 
4. LONG-TERM DEBT
 
  The Company's 12% Senior Subordinated Debentures due 2000 (the "Debentures")
bear interest at 12% per annum, payable semiannually. At March 31, 1996,
approximately $1.2 million in aggregate principal amount of the Debentures was
outstanding. On March 28, 1996, the Company gave notice of redemption, prior
to maturity, to each of the record holders of the outstanding Debentures. The
outstanding Debentures were redeemed on May 1, 1996 at a redemption price of
100.0% of the principal amount of the Debentures plus accrued and unpaid
interest thereon. On May 1, 1996, the Company deposited with the trustee of
the Debentures funds sufficient to so redeem the Debentures, and thereafter
interest on the Debentures ceased to accrue.
 
5. 10 1/2% SENIOR SUBORDINATED NOTES
 
  On March 18, 1996, the Company completed the sale of $110 million principal
amount of 10 1/2% Senior Subordinated Notes due 2006 (the "Notes"). The
proceeds of the Notes were used to fully repay the JEDI debt assumed in the
Merger and to partially repay bank debt. The Notes bear interest at an annual
rate of 10 1/2% payable semiannually in arrears on April 1 and October 1 of
each year. The Notes are general, unsecured obligations of the Company, are
subordinated in right of payment to all Senior Debt (as defined in the
Indenture governing the Notes) of Coda, and are senior in right of payment to
all future subordinated debt of the Company. The claims of the holders of the
Notes will be subordinated to Senior Debt, which, as of March 31, 1996, was
$81.8 million.
 
  The Notes were issued pursuant to an Indenture, which contains certain
covenants that, among other things, limit the ability of Coda and its
Restricted Subsidiaries to incur additional indebtedness and issue
Disqualified Stock, pay dividends, make distributions, make investments, make
certain other restricted payments, enter into certain transactions with
affiliates, dispose of certain assets, incur liens securing pari passu or
subordinated indebtedness of Coda and engage in mergers and consolidations.
 
  The Notes are not redeemable at Coda's option prior to April 1, 2001. After
April 1, 2001, the Notes will be subject to redemption at the option of Coda,
in whole or in part, at the redemption prices set forth in the Indenture, plus
accrued and unpaid interest thereon to the applicable redemption date. In
addition, until March 12, 1999, up to $27.5 million in aggregate principal
amount of Notes are redeemable, at the option of Coda on any one or more
occasions from the net proceeds of an offering of common equity of Coda, at a
price of 110.5% of the aggregate principal amount of the Notes, together with
accrued and unpaid interest thereon to the date of the redemption; provided,
however, that at least $82.5 million in aggregate principal amount of Notes
must remain outstanding immediately after the occurrence of such redemption;
provided, further, that any such redemption shall occur within 75 days of the
date of the closing of such offering of common equity.
 
  In the event of a Change of Control (as defined in the Indenture), holders
of the Notes will have the right to require Coda to repurchase their Notes, in
whole or in part, at a price in cash equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest thereon to the date of
 
                                     F-14

       NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
repurchase. The Indenture requires that, prior to such a repurchase but in any
event within 90 days of such Change of Control, Coda must either repay all
Senior Debt or obtain any required consent to such repurchase.
   
  Coda's payment obligations under the Notes are fully, unconditionally and
jointly and severally guaranteed on a senior subordinated basis by all of
Coda's current subsidiaries and future Restricted Subsidiaries (as defined in
the Indenture). Such guarantees are subordinated to the guarantees of Senior
Debt issued by the Guarantors under the Credit Agreement and to other
guarantees of Senior Debt issued in the future.     
   
  The combined condensed financial information of the Company's current
subsidiaries, the Guarantors, is as follows:

6. PREFERRED STOCK
 
  Under Coda's Restated Certificate of Incorporation, the Board of Directors
is authorized to issue up to 40,000 shares of preferred stock, par value $0.01
per share. All 40,000 shares of preferred stock are designated as "15%
Cumulative Preferred Stock." The holders of each share of Preferred Stock are
entitled to receive, when and as declared by the Board of Directors,
cumulative preferential dividends, at the rate of $150.00 per share per annum.
There are currently 20,000 shares of Preferred Stock issued and outstanding.
Shares of Preferred Stock in excess of such 20,000 shares shall be issuable
only for the purpose of paying dividends on the Preferred Stock.
 
  As long as any shares of Preferred Stock are outstanding, no dividends
whatsoever, whether paid in cash, stock or otherwise (except for dividends
paid in shares of common stock, either in the form of a stock split or stock
dividend), may be paid or declared, nor may any distribution be made, on any
common stock to the holders of such stock, unless certain conditions are met.
 
  Coda's Restated Certificate of Incorporation requires that Coda redeem all
the issued and outstanding shares of Preferred Stock at a redemption price of
$1,000 per share, plus all accrued and unpaid dividends (including undeclared
dividends) to the date of redemption, if Coda has sufficient funds legally
available for such redemption and if such redemption would not violate or
conflict with any loan agreement, credit agreement, note agreement, indenture
or other agreement relating to indebtedness to which Coda is a party, on or
before the fifth business day after the earliest to occur of the following:
(i) the closing of the sale by Coda of Taurus Energy Corp. and (ii) a Trigger
Event, as such term is defined in the Stockholders Agreement. The Preferred
Stock may be redeemed by Coda at its option, as a whole or in part, to the
extent Coda shall have funds legally available for such redemption, at any
time or from time to time at a redemption price of $1,000 per share, plus all
accrued and unpaid dividends (including undeclared dividends) to the date of
redemption. Such redemption, whether required or optional, is restricted by
the Credit Agreement and the Indenture.
 
  Upon the complete liquidation, dissolution, or winding up of Coda, whether
voluntarily or involuntarily, the holders of Preferred Stock shall be
entitled, after payment or provision for payment of the debts and other
liabilities of Coda but before any distribution is made to the holders of any
common stock, to be paid $1,000 per share plus all accrued and unpaid
dividends (including undeclared dividends), and shall not be entitled to any
further payment.
 
  Except as otherwise provided herein or required by law, the holders of
shares of Preferred Stock are not be entitled to vote on any matters to be
voted on by the stockholders of Coda; provided, however, that so long as any
shares of the Preferred Stock are outstanding, Coda shall not, without the
written consent or the affirmative vote of holders of at least a majority of
the total number of shares
of Preferred Stock then outstanding and voting as a class, (i) amend its
Certificate of Incorporation or Bylaws or (ii) authorize the merger (whether
or not Coda is a surviving corporation in such merger) of Coda, in each case,
if such amendment or merger would alter, change or abolish the powers,
preference or rights of the Preferred Stock so as to affect the holders of the
Preferred Stock adversely.
 
7. COMMON STOCK
 
  At December 31, 1995, the Company had 40.0 million shares of $.02 par value
common stock authorized with 22.1 million shares issued and outstanding. At
March 31, 1996, the Company had 1.0 million shares of $.01 par value common
stock authorized with 14,000 shares issued to management subject to put and
call rights and 900,000 issued to JEDI for a total of 914,000 shares issued

8. RELATED PARTY TRANSACTIONS
 
 SUBSCRIPTION AGREEMENT
 
  CAI entered into a Subscription Agreement dated as of October 30, 1995, as
amended by Amendment No. 1 to Subscription Agreement dated as of January 10,
1996, with members of the Management Group (as amended, the "Subscription
Agreement") which provided for the acquisition by such persons of CAI common
stock and the grant to them of nonqualified stock options to purchase shares
of post-Merger common stock (the "Replacement Options") of Coda. Under the
Subscription Agreement, each member of the Management Group who acquired CAI
common stock paid $100 per share for shares thereof, which is the same price
per share paid by JEDI for the remaining shares of CAI common stock. Under the
Subscription Agreement, the Management Group acquired CAI common stock
immediately prior to the effective time of the Merger in exchange for varying
combinations of (i) proceeds from limited recourse promissory notes payable to
CAI in the aggregate principal amount of $937,300 (the "Promissory Notes"),
(ii) Coda common stock, which was valued for this purpose at $7.75 per share,
and (iii) cash. The CAI common stock so acquired was not registered under the
Securities Act or any state securities laws and does not have the benefit of
any registration rights, but is subject to the Stockholders Agreement
described below. By virtue of the Merger, each share of CAI common stock was
converted into one share of Coda common stock.
 
  The Subscription Agreement provided that the Specified Options (representing
certain options to purchase Common Stock held by certain members of the
Management Group) and Specified Warrants (representing certain warrants to
purchase Common Stock held by certain members of the Management Group) would
not be exercised prior to the effective time of the Merger and would, as of
the effective time, be canceled without exercise and without payment of
consideration. Concurrently, the Management Group entered into Nonstatutory
Stock Option Agreements governing the Replacement Options that provided for
the right for a period of 10 years from and after the effective time of the
Merger to purchase shares of post-Merger Coda common stock for $0.01 per
share. However, the Replacement Options may only be exercised while the holder
remains an employee of the Company and for a limited period of time
thereafter. The number of shares of Coda common stock underlying the
Replacement Options each member of the Management Group received is based on
the amount of cash the holder would have received if his Specified Options or
Specified Warrants had been converted into cash in the Merger on the same
basis as other outstanding options and warrants to purchase Common Stock were
converted, divided by the $100 per share purchase price paid by JEDI and the
other Management Group members for their shares of CAI common stock. Thus, if
the Replacement Options are exercised, the holders will have effectively paid
the same purchase price per share as JEDI and the Management Group paid for
their shares of common stock of Coda.
 
  In connection with the issuance of the Replacement Options, the Company
recognized stock option compensation expense of approximately $3.2 million
representing the total amount of cash the holders of the Specified Options and
Specified Warrants would have received if such options and warrants had been
converted to cash in the Merger.
 
  The Promissory Notes will be due on February 16, 2001, bear interest at
5.61%, are secured by the Company common stock purchased with the proceeds
thereof and certain rights of the maker under the Stockholders Agreement
described below, and provide that in no event will an individual maker's
liability thereunder for any deficiency on his respective Promissory Note
(after the sale and disposition of all collateral securing same) exceed 35% of
the original principal balance of the Promissory Note.

 STOCKHOLDERS AGREEMENT
 
  CAI, JEDI and the Management Group entered into a Stockholders Agreement
dated as of October 30, 1995, as amended by Amendment No. l to Stockholders
Agreement dated as of January 10, 1996 (as amended, the "Stockholders
Agreement"), which provides generally that all parties, including JEDI and the
Management Group, (i) have rights of first refusal to acquire additional
shares of common stock of Coda that may be issued by Coda and (ii) are
restricted from transferring their Coda common stock. Coda has a right to
match any third party offer to purchase shares of Coda common stock from any
stockholder, and, in the event that Coda does not purchase those shares, the
other stockholders may have a right to include a pro rata portion of their
Coda common stock in the transaction. The Stockholders Agreement provides
that, if the employment of a member of the Management Group terminates for any
reason (including death or disability) other than his voluntary termination
(except upon retirement at age 65 or older or the expiration of the term of
any employment agreement he has with Coda) or his termination by Coda for
cause, then Coda shall have a right to purchase such member's shares of Coda
common stock at a purchase price to be determined from time to time by Coda
pursuant to a formula that values the shares on the basis of a comparison of
the discretionary cash flow and EBITDA (as defined therein) of the Company and
a group of peer companies. The Stockholders Agreement also provides that, if
the employment of a member of the Management Group terminates for any reason
other than voluntary termination or termination of such member for cause, then
such member shall have the right to require Coda to purchase such member's
shares of Coda common stock based on the previously described formula. The
purchase price under the formula will vary depending on the financial
performance of the Company and the group of peer companies. The Stockholders
Agreement provides that each member of the Management Group shall have the
right (the "Special Management Rights") to receive from JEDI, upon the
occurrence of certain events (generally an initial public offering, a business
combination with another person or the liquidation of Coda) (each, a "Trigger
Event"), an amount, which is payable in cash or additional shares of Coda
common stock depending upon the cause of the Trigger Event, designed to result
in the Management Group receiving in connection with the Trigger Event one-
third of the proceeds, attributable to the shares of Coda common stock
purchased by JEDI, above the amount of proceeds necessary for JEDI to achieve
an internal annual rate of return on that investment of 15%. The individual
member's interest in such Special Management Rights is proportional to such
member's ownership of the fully diluted common stock of Coda. The Stockholders
Agreement also provides that if the employment of a member of the Management
Group terminates, his Special Management Rights shall terminate and, if the
termination is other than a voluntary termination or a termination for cause,
he may be entitled to receive an amount based on the discretionary cash flow
and EBITDA formula discussed above. The Stockholders Agreement further
provides that, after the effective time of the Merger, Coda will establish an
employee benefit plan for the benefit of its employees who are not
members of the Management Group and will contribute to the plan 1,900 shares
of Coda common stock. Furthermore, pursuant to the Stockholders Agreement, 4%
of the Special Management Rights will be allocated thereto.
 
  The Stockholders Agreement will terminate and no party thereto will have any
further obligations or rights thereunder upon the earliest to occur of (i) the
termination of the Merger Agreement in accordance with its terms, (ii) October
30, 2005, (iii) the date on which an initial public offering of Coda common
stock or any business transaction involving Coda whereby Coda common stock
becomes a publicly traded security is consummated, (iv) the date of the
dissolution, liquidation or winding-up of Coda and (v) the date of the
delivery to Coda of a written termination notice executed by certain parties
to the Stockholders Agreement.

 ENRON
 
  Enron Corp. ("Enron") is the parent of ECT and accordingly may be deemed to
control indirectly both JEDI and the Company. Enron and certain of its
subsidiaries and other affiliates collectively participate in nearly all
phases of the oil and natural gas industry and are, therefore, competitors of
the Company. In addition, ECT and JEDI have provided, and may in the future
provide, and ECT Securities Corp. has assisted, and may in the future assist,
in arranging, financing to non-affiliated participants in the oil and natural
gas industry who are or may become competitors of the Company. Because of
these various conflicting interests, ECT, the Company, JEDI and the Management
Group have entered into the Business Opportunity Agreement which is intended
to make it clear that Enron and its affiliates have no duty to make business
opportunities available to the Company in most circumstances. The Business
Opportunity Agreement also provides that ECT and its affiliates may pursue
certain business opportunities to the exclusion of the Company. The Business
Opportunity Agreement may limit the business opportunities available to the
Company. In addition, pursuant to the Business Opportunity Agreement there may
be circumstances in which the Company will offer business opportunities to
certain affiliates of Enron. If an Enron affiliate is offered such an
opportunity and decides to pursue it, the Company may be unable to pursue it.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Coda Energy, Inc.
 
  We have audited the accompanying consolidated balance sheets of Coda Energy,
Inc., and subsidiaries (the "Company") as of December 31, 1994 and 1995, and
the related consolidated statements of operations, cash flows, and
stockholders' equity for each of the three years in the period ended December
31, 1995. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Coda Energy, Inc., and subsidiaries at December 31, 1994 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1995, in conformity with
generally accepted accounting principles.

                      CODA ENERGY, INC. AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1995
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING AND REPORTING POLICIES
 
  PRINCIPLES OF CONSOLIDATION AND BASIS OF FINANCIAL STATEMENT PRESENTATION--
The consolidated financial statements include the accounts of Coda Energy,
Inc. ("Coda"), its majority owned subsidiaries, and its pro rata share of the
assets, liabilities, and operations of oil and gas limited partnerships and
joint ventures (the "Company"). See Note 2. All significant intercompany
balances and transactions have been eliminated in consolidation. Certain
reclassifications have been made to amounts reported in prior years to conform
with the current presentation.
 
  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 these estimates.
 
  CASH AND CASH EQUIVALENTS--Cash and cash equivalents include commercial
paper or deposits with major financial institutions with maturities of three
months or less when purchased.
 
  ACCOUNTS RECEIVABLE--Substantially all of the Company's accounts receivable
arise from sales of oil, natural gas, or natural gas liquids or from
participants in oil and gas wells for which the Company serves as the
operator. Generally, operators of oil and gas properties have the right to
offset future revenues against unpaid charges related to operated wells. Oil
and gas sales are generally unsecured. Most of the Company's receivables are
from a broad and diverse group of oil and gas companies and, accordingly, do
not represent a significant credit risk. Credit losses are provided for in the
financial statements and have been within management's expectations. The
allowance for doubtful accounts receivable aggregated $185,000 and $158,000 at
December 31, 1994 and 1995, respectively.
 
  OIL AND GAS PROPERTIES--Oil and gas properties are recorded at cost using
the full cost method of accounting, as prescribed by the Securities and
Exchange Commission (the "SEC"). Under the full cost method, all costs
associated with the acquisition, exploration, or development of oil and gas
properties are capitalized as part of the full cost pool. Sales, dispositions,
and other oil and gas property retirements are accounted for as adjustments to
the full cost pool, with no recognition of gain or loss unless such
disposition would significantly alter the amortization rate. Under rules of
the SEC for the full-cost method of accounting, the net carrying value of oil
and gas properties is limited to the sum of the present value (10% discount
rate) of estimated future net cash flows from proved reserves, based on
period-end prices and costs, plus the lower of cost or estimated fair value of
unproved properties.
 
  Depletion, depreciation, and amortization of evaluated oil and gas
properties are provided using the unit-of-production method based on total
proved reserves, as determined by independent petroleum reservoir engineers.
 
  GAS PLANTS AND GATHERING SYSTEMS--Gas plants and gathering systems are
recorded at cost and depreciated on a straight-line basis over their estimated
useful lives of 15 years.
 
  OVERHEAD REIMBURSEMENT FEES--Fees from overhead charges billed to working
interest owners, including the Company, of $2,999,000, $3,372,000, and
$5,571,000 for the years ended December 31, 1993, 1994, and 1995,
respectively, have been classified as a reduction of general and
administrative expenses in the accompanying consolidated statements of
operations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                               DECEMBER 31, 1995
 
  OIL AND GAS FINANCIAL INSTRUMENTS--The Company enters into swap agreements
to reduce the effects of the volatility of the price of crude oil and natural
gas on the Company's operations. These agreements involve the receipt of fixed
price amounts in exchange for variable payments based on NYMEX prices and
specific volumes. The differential to be paid or received is accrued in the
month of the related production and recognized as a component of oil and gas
revenues.
 
  The Company also sells call options on crude oil. The strike price of these
agreements exceeds current market prices at the time they are entered into.
Option premiums received, which have not been material, are deferred. If the
applicable market price exceeds the strike price and option premium, the
differential is accrued and recognized as a reduction of oil revenues in the
month of the related production. Any remaining deferred option premiums are
recognized at the end of the option period.
 
  The fair values of the swap agreements and sold call options are not
included in the financial statements.
 
  INCOME TAXES--The Company has adopted the Financial Accounting Standards
Board's Statement No. 109, "Accounting for Income Taxes" ("FAS 109"), which
requires the use of the liability method in accounting for income taxes.
 
  QUASI-REORGANIZATION--In 1989, the Company, with the approval of the Board
of Directors, implemented a quasi-reorganization and adjusted its assets and
liabilities to fair value at June 30, 1989; eliminated accumulated depletion,
depreciation, and amortization existing on all properties at June 30, 1989,
against the respective asset accounts; and transferred the accumulated deficit
at June 30, 1989, of $39,663,000 and the cost of canceled treasury stock of
$1,809,000 to additional paid-in capital.
 
  NEW ACCOUNTING PRONOUNCEMENTS--In the first quarter of 1996, the Company
will adopt the Financial Accounting Standards Board ("FASB") Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed of" ("FAS 121"). Adoption of this statement will not
have a material effect on the Company's financial statements.
 
  In October 1995, the FASB issued its statement No. 123, "Accounting for
Stock Based Compensation" ("FAS 123") which establishes an alternative method
of accounting for stock based compensation to the method set forth in
Accounting Principles Board Opinion No. 25 ("APB 25"). FAS 123 encourages, but
does not require, adoption of a fair value based method of accounting for
stock options and similar equity instruments granted to employees. The Company
will continue to account for such grants under the provisions of APB 25 and
will adopt the disclosure provisions of FAS 123 in the first quarter of 1996.
Accordingly, adoption of FAS 123 will not effect the Company's financial
statements.
 
2. MERGER WITH DIAMOND
 
  On September 30, 1994, pursuant to an Agreement and Plan of Merger (the
"Merger Agreement"), the Company acquired all of the issued and outstanding
stock of Diamond Energy Operating Company and Diamond A Inc. ("DEOC" and
"Diamond A," respectively, and collectively, "Diamond"), and two newly formed,
wholly owned subsidiaries of the Company merged into DEOC and Diamond A. The
Company issued an aggregate of 3,647,715 shares of the Company's common stock
to the Diamond stockholders. Contemporaneously with the merger, Diamond
acquired the

                               DECEMBER 31, 1995
overriding royalty and reversionary interests owned by Diamond's primary
lender in certain of Diamond's oil and gas properties for $9.0 million cash.
Coda provided the funds necessary to complete such acquisition and repay $18.5
million of existing Diamond indebtedness. If the price of oil received from
the Diamond properties averages more than $17.65 per barrel for the 48-month
period ending September 30, 1998, Diamond's former lender will be paid an
additional $1.0 million. In addition, other reversionary interests in oil and
gas properties in which Diamond owns an interest were purchased from certain
employees and former employees of, and consultants to, DEOC and from a
financial advisor to Diamond for 634,519 shares of the Company's common stock
and approximately $39,000 in cash.
 
  The merger with Diamond has been accounted for as a pooling of interests.
Accordingly, the merger of the equity interests has been given retroactive
effect in these financial statements for periods prior to the merger to
represent the combined financial statements of the previously separate
entities. The acquisitions of the reversionary interests were accounted for as
purchases effective September 30, 1994.
 
  Separate and combined results of Coda and Diamond for periods prior to the
merger are as follows (in thousands):

  In connection with the merger, the Company incurred approximately $1.8
million of legal, accounting, printing, and other costs related to the
combination of the previously separate entities. Under pooling of interests
accounting, these costs were expensed in September 1994.
 
  Amounts due from stockholders shown in the accompanying balance sheets are
primarily related to the sale by DEOC of its oil and gas properties to its
stockholders in July 1990 in exchange for a note receivable. The note bears
interest at 10% and is due on demand. Interest is added to the principal
balance as accrued. The note is secured by certain of the shares of Coda
common stock which the former Diamond stockholders received in the merger.
 
3. ACQUISITIONS
 
  The Company is continually acquiring oil and gas properties. The significant
transactions that have occurred since January 1, 1993, are discussed below.
 
  In July 1993, the Company acquired interests in 71 producing oil and gas
properties effective June 1, 1993, located primarily in the Morrow and Chester
formations in southwest Kansas (the "Kansas Properties"), from affiliates of
Mobil Oil Corp. The total purchase price for the Kansas Properties was
$15,800,000, all of which was funded pursuant to the Company's credit
agreement.
 
  In September 1993, the Company purchased all of the issued and outstanding
shares of MJM Oil & Gas, Inc. ("MJM"). The total purchase price was
$5,650,000, all of which was funded from the net

proceeds of a public offering of common stock (Note 5). The acquisition was
accounted for as a purchase. As a result of the acquisition of MJM, the
Company acquired 147 producing oil and gas properties, located primarily in
north and west Texas and western Oklahoma, at a cost of approximately $19.9
million, including the assumption of approximately $11.7 million of MJM
indebtedness.
 
  On April 29, 1994, Coda acquired 100% of the issued and outstanding common
stock of Taurus Energy Corporation ("Taurus"), a privately held Texas
corporation, in exchange for 1,500,000 shares of the Company's common stock,
valued at approximately $7.3 million, and $3.25 million cash. The Company
assumed existing Taurus indebtedness of approximately $9.75 million. The cash
portion of the purchase price was funded, and the assumed debt was refinanced,
under the Company's existing credit agreement. Taurus operates three natural
gas processing facilities and owns interests in approximately 700 miles of
natural gas gathering systems located primarily in west central Texas.
 
  Contemporaneously with the consummation of the acquisition of Taurus, the
president and former principal stockholder of Taurus loaned the Company $1.0
million in exchange for a subordinated promissory note from the Company having
a term of three years, payable in three equal annual installments of principal
plus accrued interest calculated at the rate of 7% per annum.
 
  In July 1994, Taurus acquired ownership of the Shackelford gas gathering
system and processing plant. Taurus had previously been operating the system
and plant under operating leases. Taurus paid $3.8 million for the system and
plant, which was funded under the Company's existing credit agreement. In
related transactions, Taurus entered into an agreement to sell 10,000 MMBTU
per day to the former owner of Shackelford for a period of 48 months.
Simultaneously, Taurus entered into a gas purchase agreement with an unrelated
third party for similar quantities over the same term. Pricing under both the
gas sales agreement and the gas purchase agreement is structured to allow
Taurus to earn a margin on all volumes sold during the term of the agreements.
In January 1995, Taurus acquired the remaining ownership interest in one of
Taurus' gas plants and related facilities for $6.5 million which was financed
under the Company's credit facility.
 
  In December 1994, in two separate transactions, the Company acquired
interests in 31 producing oil and gas properties in west Texas from two major
oil companies. The acquisition prices were $13.3 million and $10.0 million,
respectively, all of which was financed under the Company's credit facility.
The acquisitions were accounted for as a purchase. The properties acquired for
$13.3 million are referred to herein as the Major Oil Company Properties.
 
  In October 1995, Coda acquired from Snyder Oil Company interests in 63
producing oil and gas properties located in west Texas (the "Snyder
Properties"). The aggregate purchase price was $17.1 million in cash, of which
$16.0 million was financed by borrowings under the Company's existing credit
facility. The acquisition was accounted for by the purchase method of
accounting.
 
  The following pro forma data present the consolidated results of operations
of the Company for the years ended December 31, 1994 and 1995, as if the
acquisitions of Taurus, the Major Oil Company Properties, and the Snyder
Properties had occurred on January 1, 1994. The pro forma results of
operations are presented for comparative purposes only and are not necessarily
indicative of the results that would have been obtained had such acquisitions
been consummated as presented. The following data reflect pro forma
adjustments for depletion, depreciation, and amortization related to the
acquired oil and gas properties, gas plants, and gathering systems;

  NATIONSBANK CREDIT AGREEMENTS--Until the merger with JEDI on February 16,
1996 (Note 9), the Company had a credit agreement (the "Credit Agreement")
with NationsBank of Texas, N.A. ("NationsBank") and three additional
participant banks. The Credit Agreement as last amended through August 1995
had a notional amount of $250.0 million, subject to borrowing base
limitations, based on the value of the Company's oil and gas properties and
its gas gathering and processing assets, as determined by the lenders from
time to time. Under the Credit Agreement, the Company was required to pay a
facility fee equal to one-quarter of one percent on any accepted increase in
the borrowing base in excess of the previously determined borrowing base and a
commitment fee of three-eighths of one percent on the unused portion of the
borrowing base. The maturity date of the Credit Agreement was May 31, 1999.
 
  The Credit Agreement provided that the interest rate on borrowings will
range from NationsBank's prime rate to LIBOR plus between 1% and 1 3/8% based
on the ratio of outstanding debt to the available borrowing base. The weighted
average interest rate on borrowings outstanding under the Credit Agreement was
7.72% and 7.29% at December 31, 1994 and 1995, respectively.
 
  There were no scheduled principal payments due on the Credit Agreement until
maturity. At December 31, 1995, the borrowing base was $125.0 million and
approximately $3.0 million was available for borrowing. A borrowing base
deficiency is created in the event that the outstanding loan balances exceed
the borrowing base, as determined by the lenders in their sole discretion.
Upon such event, the borrowing base deficiency must be repaid by mandatory
reductions of the loan balances over a period of not more than six months. The
Company did not anticipate a borrowing base

deficiency, and, accordingly, the current portion of long-term debt at
December 31, 1995, does not include any amount related to the Credit
Agreement.
 
  Borrowings under the Credit Agreement were unsecured. The Credit Agreement
contained various restrictive covenants, including limitations on the granting
of liens, restrictions on the issuance of additional debt, requirements to
maintain net worth of at least $46.5 million and to maintain positive working
capital, as defined, and prohibited the payment of dividends on Coda's capital
stock.
 
  NOTE PAYABLE TO NATIONSBANK--In December 1992, the Company purchased a
building in Dallas, Texas, containing approximately 65,000 square feet of
office space to serve as its corporate headquarters. The Company currently
occupies approximately two-thirds of the office space and has made the balance
available for lease. The purchase price was $950,000, of which $850,000 was
financed by NationsBank pursuant to a promissory note requiring monthly
principal and interest payments, with the remaining unpaid balance due
December 31, 1995. The promissory note bears interest at prime plus 1%. The
remainder of the purchase price was financed by the seller and is evidenced by
a second lien promissory note requiring quarterly interest payments. In
February 1995, NationsBank agreed to amend the note payable to reduce the
interest rate to NationsBank's prime rate and to extend the maturity date to
January 2, 1998.
 
  SENIOR SUBORDINATED DEBENTURES--The Company's 12% Senior Subordinated
Debentures (the "Debentures") are presented net of unamortized issuance
discount of $189,000 and $165,000 at December 31, 1994 and 1995, respectively.
The effective interest rate on the Debentures is 16.61%. The remaining
outstanding Debentures are due in 2000.

5. COMMON STOCK
 
  COMMON STOCK--On September 30, 1994, the Company's stockholders approved an
amendment to the Company's Certificate of Incorporation increasing the number
of authorized shares of common stock from 30 million shares to 40 million
shares.
 
  In September 1993, the Company sold 6,788,750 shares of common stock
pursuant to a public offering. The net proceeds of approximately $36.1 million
to the Company were used to purchase the capital stock of MJM (Note 3), to
repay certain MJM indebtedness (approximately $900,000), and to repay amounts
under the Company's Credit Agreement.
 
  In December 1993, the Board of Directors authorized the repurchase of up to
3,000,000 shares of the Company's common stock, from time to time and
whenever, in the opinion of the Company's

management, market conditions make such repurchase a prudent use of Company
funds. In January 1994, the Company received written approval for such
repurchases from NationsBank provided that the amount paid does not exceed
$5,000,000 in the aggregate. No shares had been repurchased as of December 31,
1993. During the year ended December 31, 1994 and 1995, the Company
repurchased and canceled 136,500 and 371,000 shares of common stock,
respectively, in open market transactions at a cost of approximately $648,000
and $2.1 million, respectively.
 
  STOCK OPTIONS AND WARRANTS--The Company has three stock option plans
providing for the granting of stock options to officers and key employees.
Compensation expense is not recognized at the time options are granted because
the option price per share represents the market value of the share at the
date of grant.
 
  The 1986 Non-Qualified Stock Option Plan provides that options may be
granted, from time to time, to key employees and directors to purchase a
maximum of 180,000 shares of common stock. The 1989 Incentive Stock Option
Plan provides that options may be granted, from time to time, to key employees
to purchase a maximum of 750,000 shares of common stock. The 1993 Incentive
Stock Option Plan permits the granting of options to purchase up to 1,500,000
shares of common stock.

  At December 31, 1995, Coda has net operating loss carryforwards ("NOLs") for
income tax purposes that expire beginning in 1998. Utilization of the NOLs is
severely restricted because of a change in ownership, as defined by the Tax
Reform Act of 1986, of Coda, which occurred in March 1990. Coda estimates that
approximately $15.4 million of the NOLs is available to offset future taxable
income without limitation, while the remainder will become available in the
future at the rate of approximately $921,000 per year through 2004. Coda also
has available statutory depletion carryforwards of approximately $1,000,000.
For financial reporting purposes, a valuation allowance has been recognized to
offset the deferred tax assets related to carryforwards prior to Coda's quasi-
reorganization. The Company anticipates that the merger described in Note 9
will not have a material effect on its ability to utilize the remaining NOLs.

whose predominant economic value is attributable to proved producing reserves
and to enhance that value through control of operations, reduction of costs,
and property development. The Company's producing properties are concentrated
in the mid-continent region of the United States. Through a subsidiary,
Taurus, the Company also operates natural gas processing and liquid extraction
facilities and natural gas gathering systems.

  All of the Company's oil and gas revenues are from proved developed
properties located in the United States.
 
  The Company has capitalized internal costs of $658,000, $712,000, and
$748,000 for the years ended December 31, 1993, 1994, and 1995, respectively.
Such capitalized costs include salaries and related benefits of individuals
directly involved in the Company's acquisition, exploration, and development
activities based on the percentage of their time devoted to such activities.
 
  During the year ended December 31, 1993, sales of oil and gas to two
purchasers accounted for 21% and 22% of consolidated gross revenues. During
the year ended December 31, 1994, sales of oil and gas to two purchasers
accounted for 13% and 22% of consolidated gross revenues. During the year
ended December 31, 1995, sales of oil and gas to two purchasers accounted for
10% and 18% of consolidated gross revenues. Management believes that the loss
of these purchasers would not have a material impact on the Company's
consolidated financial condition or results of operations.

  During the fourth quarter of 1993, the Company received a payment of oil and
gas revenues relating to a recalculation of interests owned in certain of the
Company's properties for the period from 1985 through 1993. Oil and gas sales
increased by $343,000 as a result.
 
 OIL AND GAS HEDGING ACTIVITIES AND COMMITMENTS
 
  In an effort to reduce the effects of the volatility of the price of crude
oil and natural gas on the Company's operations, management has adopted a
policy of hedging oil and gas prices whenever such prices are in excess of the
prices anticipated in the Company's operating budget and profit plan through
the use of commodity futures, options, and swap agreements. The Company does
not hold or issue financial instruments for trading purposes. Hedging
transactions require the approval of the Board of Directors.
 
  While the use of these hedging arrangements limits the downside risk of
adverse price movements, it may also limit future gains from favorable
movements. All hedging is accomplished pursuant to exchange-traded contracts
or master swap agreements based upon standard forms. The Company addresses
market risk by selecting instruments whose value fluctuations correlate
strongly with the underlying commodity being hedged. Credit risk related to
hedging activities, which is minimal, is managed by requiring minimum credit
standards for counterparties, periodic settlements, and marked to market
valuations. The Company has not historically been required to provide any
significant amount of collateral relating to its hedging activities.
 
  At December 31, 1995, the Company had entered into various swap agreements
to fix selling prices for crude oil at a weighted average NYMEX price of
$18.79 and $19.02 per barrel for 740,000 and 375,000 barrels during 1996 and
1997, respectively. While these contracts have no carrying value, their fair
value (the estimated amount that would have been received upon termination of
the swaps at December 31, 1995) was approximately $900,000.
 
  The Company has also sold call options covering 25,000 Bbls of oil per month
at an option price of $18.30 per Bbl for the period October 1995 to August
1996, and at an option price of $20.00 per barrel for the period September
1996 to August 1997. While these call options have no carrying value, their
fair value (the estimated amount that would have been paid by the Company upon
termination of the call options at December 31, 1995) was approximately
$230,000.
 
  During the years ended December 31, 1993, 1994, and 1995, oil and gas sales
were reduced by $289,000 and $5,000, and increased by $298,000, respectively,
as a result of hedging transactions.
 
  Pursuant to the loan agreements with Diamond's former lender, Diamond
entered into an agreement with a refining and marketing company to sell a
fixed number of barrels attributable to its share of production of liquid
hydrocarbons from certain secured properties at a price of $15.25 per Bbl.
Under the purchase and sale agreement, the remaining commitment was
approximately 47,000 Bbls at December 31, 1995. The Company expects to fulfill
this commitment during the first quarter of 1996.
 
8. COMMITMENTS AND CONTINGENCIES
 
  The Company does not believe that future costs related to site restoration,
dismantlement, and abandonment costs, net of estimated salvage values, will
have a significant effect on its results of

operations or financial position because the salvage value of equipment and
related facilities should approximate or exceed any future expenditures for
restoration, dismantlement, or abandonment. The Company has not incurred any
net expenditures for costs of this nature during the last three years.
 
  The Company is a defendant or co-defendant in minor lawsuits that have
arisen in the ordinary course of business. In the lawsuits, management
believes, based in part on advice from legal counsel, that the Company has
meritorious defense against the claims asserted. Management believes that the
ultimate resolution of the lawsuits and claims will not have a material
adverse effect on the Company's results of operations or financial position.
 
9. AGREEMENT AND PLAN OF MERGER
 
  On February 16, 1996, pursuant to an Agreement and Plan of Merger dated as
of October 30, 1995 (as amended, the "Merger Agreement") by and among Coda,
Joint Energy Development Investments Limited Partnership ("JEDI"), an
affiliate of Enron Capital & Trade Resources Corp., and Coda Acquisition, Inc.
("Purchaser"), a subsidiary of JEDI, JEDI acquired Coda through a merger (the
"Merger") at a price of $7.75 per share in cash. Concurrently with the
execution of the Merger Agreement, JEDI and Purchaser entered into certain
agreements with certain members of the Company's management concerning their
employment with and/or equity participation in the Company after the Merger.
 
  The sources and uses of funds related to the Merger were as follows (in
millions):

</TABLE>
 
  The Merger has been accounted for using the purchase method of accounting.
As such, JEDI's cost of acquiring Coda has been allocated to the assets and
liabilities acquired based on estimated fair values. As a result, the
Company's financial position and operating results subsequent to February 16,
1996 will reflect a new basis of accounting and are not comparable to prior
periods.
 
10. 10 1/2% SENIOR SUBORDINATED NOTES
 
  On March 18, 1996, the Company completed the sale of $110 million principal
amount of 10 1/2% Senior Subordinated Notes due 2006 (the "Notes"). The
proceeds of the Notes were used to fully repay the JEDI Debt assumed in the
Merger and to partially repay bank debt. The Notes bear interest at an annual
rate of 10 1/2% payable semiannually in arrears on April 1 and October 1 of
each year. The Notes are general, unsecured obligations of the Company, are
subordinated in right of payment to all Senior Debt (as defined in the
Indenture governing the Notes) of Coda, and are senior in right of payment to
all future subordinated debt of the Company. The claims of the holders of the
Notes will be subordinated to Senior Debt, which, as of March 31, 1996, was
$81.8 million.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                               DECEMBER 31, 1995
 
  The Notes were issued pursuant to an Indenture, which contains certain
covenants that, among other things, limit the ability of Coda and its
Restricted Subsidiaries (as defined in the Indenture) to incur additional
indebtedness and issue Disqualified Stock, pay dividends, make distributions,
make investments, make certain other restricted payments, enter into certain
transactions with affiliates, dispose of certain assets, incur liens securing
pari passu or subordinated indebtedness of Coda and engage in mergers and
consolidations.
 
  The Notes are not redeemable at Coda's option prior to April 1, 2001. After
April 1, 2001, the Notes will be subject to redemption at the option of Coda,
in whole or in part, at the redemption prices set forth in the Indenture, plus
accrued and unpaid interest thereon to the applicable redemption date. In
addition, until March 12, 1999, up to $27.5 million in aggregate principal
amount of Notes are redeemable, at the option of Coda on any one or more
occasions from the net proceeds of an offering of common equity of Coda, at a
price of 110.5% of the aggregate principal amount of the Notes, together with
accrued and unpaid interest thereon to the date of the redemption; provided,
however, that at least $82.5 million in aggregate principal amount of Notes
must remain outstanding immediately after the occurrence of such redemption;
provided, further, that any such redemption shall occur within 75 days of the
date of the closing of such offering of common equity.
 
  In the event of a Change of Control (as defined in the Indenture), holders
of the Notes will have the right to require Coda to repurchase their Notes, in
whole or in part, at a price in cash equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest thereon to the date of
repurchase. The Indenture requires that, prior to such a repurchase but in any
event within 90 days of such Change of Control, Coda must either repay all
Senior Debt or obtain any required consent to such repurchase.
 
  Coda's payment obligations under the Notes are fully, unconditionally and
jointly and severally guaranteed on a senior subordinated basis by all of
Coda's current subsidiaries and future Restricted Subsidiaries. Such
guarantees are subordinated to the guarantees of Senior Debt issued by the
Guarantors under the Credit Agreement and to other guarantees of Senior Debt
issued in the future.
 
  The combined condensed financial information of the Company's current
subsidiaries, the Guarantors, is as follows:

11. SUPPLEMENTAL OIL AND GAS RESERVE AND STANDARDIZED MEASURE INFORMATION
(UNAUDITED)
 
  The Company retains independent engineering firms to provide annual year-end
estimates of the Company's future net recoverable oil, gas, and natural gas
liquids reserves. Estimated proved net recoverable reserves as shown below
include only those quantities that can be expected to be commercially
recoverable at prices and costs in effect at the balance sheet dates under
existing regulatory practices and with conventional equipment and operating
methods. Proved developed reserves represent only those reserves expected to
be recovered through existing wells. Proved undeveloped reserves include those
reserves expected to be recovered from new wells on undrilled acreage or from
existing wells on which a relatively major expenditure is required for
recompletion.
 
  Reserve estimates are imprecise and may be expected to change as additional
information becomes available. Furthermore, estimates of oil and gas reserves,
of necessity, are projections based on engineering data, and there are
uncertainties inherent in the interpretation of such data as well as the
projection of future rates of production and the timing of development
expenditures. Reserve engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
way, and the accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment.
Accordingly, there can be no assurance that the reserves set forth herein will
ultimately be produced nor can there be assurance that the proved undeveloped
reserves will be developed within the periods anticipated. The Company
emphasizes with respect to the estimates prepared by independent petroleum
engineers that the discounted future net cash inflows should not be construed
as representative of the fair market value of the proved oil and gas
properties belonging to the Company, since discounted future net cash inflows
are based upon projected cash inflows which do not provide for changes in oil
and gas prices nor for escalation of expenses and capital costs. The
meaningfulness of such estimates is highly dependent upon the accuracy of the
assumptions upon which they were based.

  The following is a summary of a standardized measure of discounted net cash
flows related to the Company's proved oil, gas, and natural gas liquids
reserves. The information presented is based on a valuation of proved reserves
using discounted cash flows based on year-end prices, costs, and economic
conditions and a 10% discount rate. The additions to proved reserves from new
discoveries and extensions could vary significantly from year to year;
additionally, the impact of changes to reflect current prices and costs of
reserves proved in prior years could also be significant. Accordingly, the
information presented below should not be viewed as an estimate of the fair
value of the Company's oil and gas properties, nor should it be considered
indicative of any trends.

  During recent years, there have been significant fluctuations in the prices
paid for crude oil in the world markets. This situation has had a
destabilizing effect on crude oil's posted prices in the United States,
including the posted prices paid by purchasers of the Company's crude oil. The
weighted average prices of oil and gas at December 31, 1994 and 1995, used in
the above table, were $16.24 and $18.31 per Bbl, respectively, and $1.45 and
$2.19 per Mcf, respectively.

This report is based on assumptions provided by Coda Energy, Inc. Oil and gas 
prices and expenses used in this appraisal were held constant throughout the 
anticipated life of the properties.

Future net revenue is the amount, exclusive of state and federal income taxes, 
which will accrue to the appraised interests from continued operation of the 
properties to depletion.  It should not be construed as a fair market or trading
value.  No provision has been made for the cost of plugging and abandoning the 
properties nor for the value of salvable equipment.

No attempt has been made to quantify or otherwise account for any accumulative 
gas production imbalances that may exist.  Neither has an attempt been made to 
determine whether the wells and facilities are in compliance with various 
governmental regulations, nor have costs been included in the event they are 
not.

This report consists of two volumes.  Volume I includes summary forecasts of 
annual gross and net production, severance and ad valorem taxes, operating 
income and net revenue, and present worth determinations at various discount 
rates by reserve type.  The company totals are summarized in Schedule No. 1. 
Schedule No. 2 is a one-line summary of the individual properties arranged 
alphabetically.  Schedule No. 3 is a sequential listing of the individual 
properties based on discounted future net revenue.  Volume II contains 
determination of future net revenue for the individual properties.


CLASSIFICATION OF RESERVES
- --------------------------

Reserves attributed to the appraised leases have been classified "proved 
producing," "proved non-producing," proved behind-pipe," "proved 
undeveloped," "probable," and "possible."

Proved producing reserves are those expected to be recovered from currently 
- -------------------------
producing zones under continuation of present operating methods.

Proved non-producing reserves are those attributable to wells which have been 
- -----------------------------
drilled, but for various reasons, cannot be classified as producing.  This 
category may also contain reserves attributable to developed waterflood units 
for which no response has been experienced.

Proved behind-pipe reserves are those currently behind the pipe in existing 
- ---------------------------
wells which are considered proved by virtue of successful testing or production 
in offsetting wells.

Proved undeveloped reserves are those attributable to wells to be drilled at 
- ---------------------------
locations which can be considered proved by virtue of favorable structural 
position and which can be anticipated with a high degree of certainty.

                                      A-2
<PAGE>
 
Proved undeveloped reserves also include those attributable to undeveloped 
- ---------------------------
repressuring or pressure maintenance projects in zones whose reserves are 
considered proved by virtue of successful pilot projects or successful projects 
which involve those zones in the vicinity. Projects to which this category of 
reserves has been assigned are either in the process of formation or can be 
expected with a high degree of certainty to be formed in the near future.

Probable reserves are those anticipated from zones in existing wells or from 
- -----------------
wells to be drilled at locations that cannot be considered proved for lack of 
actual physical testing, production in the area and/or limited geologic control.
These can be either primary or secondary reserves.

Possible reserves are those based on criteria similar to those discussed under 
- -----------------
probable reserves but which must be considered more speculative. These also can 
be either primary or secondary reserves.

ESTIMATION OF RESERVES
- ----------------------

The majority of the appraised wells have been producing for a considerable 
length of time. Reserves attributable to wells with well-defined production 
trends and/or well-defined cumulative recovery-pressure relationships were based
upon extrapolation of these trends or relationships to economic limits and/or 
abandonment pressures.

Reserves anticipated from new wells were based upon volumetric calculations or 
analogy with similar properties which are producing from the same horizons in 
the respective areas. Structural position, net pay thickness, well productivity,
gas/oil ratios, water production, pressures, and other pertinent factors were 
considered in the estimations of these reserves.

Reserves assigned to behind-pipe zones have been estimated based on volumetric 
calculation and/or analogy with other wells in the area producing from the same 
horizon.

Primary reserves attributable to undeveloped locations have been based on 
analogy with offsetting wells.

Undeveloped secondary reserves, attributable to additional development of 
existing waterflood projects, have been based on analogy with the respective 
projects or other secondary projects in the area with similar characteristics.

The proved reserves included in this report conform to the applicable definition
promulgated by the Securities and Exchange Commission.

FUTURE NET REVENUE
- ------------------

Oil Income
- ----------

Income from the sale of oil was established using the December 31, 1995, posted 
West Texas Intermediate price of $18.00 per barrel. A comparison was made 
between the West Texas Intermediate price during 1995 and the prices actually 
received for each lease during the same time period. A difference between West 
Texas Intermediate and actual pricing was determined and this adjustment was 
applied to the December 31, 1995, West Texas Intermediate posting on a lease 
basis.

For leases with known contracts or fixed prices, that price was used instead of 
the relationship to West Texas Intermediate posting. All prices were held 
constant throughout the life of each lease. Provisions were made for state 
severance and ad valorem taxes where applicable.

Gas Income
- ----------

Income from the sale of gas from each lease was based on the December 31, 1995 
Henry Hub price of $2.26 per MCF. A comparison was made between the Henry Hub 
price during 1995 and the price actually received for each lease during the 
same time period. A difference between Henry Hub and actual pricing was 
determined and this adjustment was applied to the December 31, 1995 Henry Hub 
price on a lease basis.

For leases with known contracts or fixed prices, that price was used instead of 
the relationship to the Henry Hub price. All prices were held constant 
throughout the life of each lease. Adjustments were made for state severance and
ad valorem taxes where applicable.

Operating Expenses
- ------------------

Operating expenses were based upon actual operating costs charged by the 
respective operators as supplied by the staff of Coda Energy, Inc., or were 
based upon the actual experience of the operators in the respective areas. For 
leases operated by Coda Energy, Inc., monthly lease operating expenses do not 
include overhead charges. All expenses have been held constant throughout the 
life of each lease.

GENERAL
- -------

Information upon which this appraisal has been based was furnished by the staff 
of Coda Energy, Inc. or was obtained by us from outside sources. This 
information is assumed to be correct. No attempt has been made to verify title 
or ownership of the appraised properties.

Leases were not inspected by a representative of this firm, nor were the wells 
tested under our supervision; however, the performance of the majority of the 
wells was discussed with employees of Coda Energy, Inc.

This report has been prepared utilizing methods and procedures regularly used by
petroleum engineers to estimate oil and gas reserves for properties of this type
and character.  The recovery of oil and gas reserves and projection of producing
rates are dependent upon many variable factors.  These include, among others, 
prudent operation, compression of gas when needed, market demand, installation 
of lifting equipment and remedial work when required.  The reserves included in 
this report have been based upon the assumption that the wells will continue to 
be operated in a prudent manner under the same conditions existing at the 
present time.  Actual production results and future well data may yield 
additional facts, not presently available to us, which will require an 
adjustment to our estimates.

The reserves included in this report are estimates only and should not be 
construed as being exact quantities.  They may or may not be actually recovered,
and, if recovered, the revenues therefrom and the actual costs related thereto 
could be more or less than the estimated amounts.  As in all aspects of oil and 
gas evaluation, therefore are uncertainties inherent in the interpretation of 
engineering data and, therefore, our conclusions necessarily represent only 
informed professional judgments.

You should be aware that state regulatory authorities could, in the future, 
change the allocation of reserves allowed to be produced from a particular well 
in any reservoir, thereby altering the material premise upon which our reserve 
estimate may be based.

The projection of cash flow has been made assuming constant prices.  There is 
no assurance that prices will not vary.  For this reason and those listed in 
the previous paragraph, the future net cash from the sale of production from the
appraised properties may vary from the estimates contained in this report.

The information developed during the course of this investigation, basic data, 
maps and worksheets showing recovery determinations are available for inspection
in our office.

We appreciate this opportunity to be of service to you.

                                       Very truly yours,
