ITEM 1.  CHANGES IN CONTROL OF THE REGISTRANT

         On November 26, 1997, Belco Oil & Gas Corp., a Nevada corporation
("Belco"), completed the merger (the "Merger") of its subsidiary Belco
Acquisition Sub, Inc., a Delaware corporation ("Belco Sub"), with and into Coda
Energy, Inc., a Delaware corporation ("Coda"), and Belco is now the beneficial
owner of 100% of the voting securities of Coda.

         The Merger was effected pursuant to the terms of an Agreement and Plan
of Merger, dated as of October 31, 1997, by and among Belco, Belco Sub and Coda
(the "Merger Agreement").  In connection with the Merger, Belco paid an
aggregate of approximately $191 million in cash ($149 million plus a $42
million adjustment for proceeds from the Taurus disposition described below)
and issued warrants to purchase 1,666,667 shares of common stock, par value
$0.01 per share, of Belco (the "Belco Common Stock") to the holders of the
outstanding common stock, preferred stock and options to purchase common stock
of Coda.  The warrants are exercisable for a period of two years commencing on
November 26, 1998 at an exercise price of $27.50 per share.  The warrant
exercise price and the number of shares of Belco Common Stock that may be
issued pursuant to the exercise of the warrants will be adjusted to prevent
dilution in the event of stock splits, stock dividends and certain other events
affecting the capital structure of Belco.

         The holders of Coda's common stock, preferred stock and options to
acquire Coda common stock who received consideration from Belco pursuant to the
Merger consisted of Joint Energy Development Investments Limited Partnership, a
Delaware limited partnership ("JEDI"), and members of Coda's management.  The
consideration paid and issued by Belco in connection with the Merger was
determined by arms' length negotiations among Belco, Coda and certain
stockholders of Coda, including JEDI (the holder of 95% of the Coda common
stock, on a fully diluted basis, and 100% of the Coda preferred stock
outstanding immediately prior to the Merger).  JEDI is a limited partnership
whose general partner is an affiliate of Enron Capital & Trade Resources Corp.,
a subsidiary of Enron Corp. ("Enron").  Mr. Robert A. Belfer, the Chairman of
the Board and Chief Executive Officer of Belco and the beneficial owner of
approximately  39%  of the outstanding Belco Common Stock, is also a director
and the beneficial owner of approximately 2.36% of the common stock of Enron
(assuming full conversion into shares of common stock of Enron of Preferred
Convertible  Stock of Enron held by Mr. Belfer, family members and related
trusts and including shares of common stock in which Mr. Belfer disclaims
beneficial interest).

         On November 25, 1997 (prior to the Merger), Coda disposed of Taurus
Energy Corp., a Texas corporation ("Taurus Corp."), which was a subsidiary of
Coda, to unrelated third parties for $42 million in cash, which is described in
Item 2 below.  Concurrently with the Merger, Belco contributed $23 million to
Coda that Coda utilized, together with the funds from the Taurus disposition,
to repay all of the debt outstanding under Coda's revolving credit facility
(approximately $65 million in principal amount), plus accrued interest thereon,
at the time of the Merger, and such credit facility was thereafter terminated.
Belco funded the cash portion of the Merger consideration and the cash
contribution to Coda through cash on hand and borrowings under Belco's $150
million revolving credit facility with a group of banks for which The Chase
Manhattan Bank acts as Administrative Agent.

         As a result of the Merger, Coda will be required to make an offer to
purchase all of the $110 million in principal amount of its 10 1/2% Senior
Subordinated Notes, Series B, due 2006 (the "Coda Notes") currently outstanding
at a price equal to 101% of the principal amount of the Coda Notes plus accrued
and unpaid interest thereon.  Notice of such offer is required to be made
within 30 days following the closing of the Merger and such offer is required
to remain open for a period of between 30 and 60 days.

ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         On November 25, 1997 Coda completed the disposition (the
"Disposition") of Taurus Corp., which was a wholly owned subsidiary of Coda, to
Continental Natural Gas, Inc., an Oklahoma corporation ("CNG") and certain of
its affiliates.  The assets of Taurus Corp. consisted primarily of two natural
gas processing facilities and approximately 700 miles of related gathering
pipelines located in West Texas.

         The Disposition was effected pursuant to the terms of an Agreement and
Plan of Merger dated as of November 24, 1997, by and among Coda, Taurus
Holdings Corp., CNG, Continental/Taurus Holdings Company, L.L.C.,
Continental/Taurus Acquisition Corp. and Continental Holdings Company.  CNG and
its affiliates paid Coda an aggregate of $42 million in cash for Taurus Corp.

         CNG and its affiliates are unrelated parties to Coda and its
affiliates.  The consideration paid by CNG and its affiliates to Coda was
determined by arm's length negotiations between Coda and CNG.

         As a result of the Disposition, the guarantee of the Coda Notes by
Taurus Corp. was terminated.

          NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

BASIS OF PRESENTATION

   The unaudited pro forma condensed statements of operations are based on the
audited statements of Coda for the 319- day period ended December 31, 1996 and
on the unaudited statements of Coda for the 47-day period ended February 16,
1996 and the nine months ended September 30, 1997.  The pro forma information
adjusts the Company's historical results of operations for the sale of Taurus
based upon the adjustments and assumptions described below.

   The pro forma balance sheets are based on Coda's unaudited balance sheet as
of September 30, 1997 and upon the adjustments and assumptions described below.

PRO FORMA ADJUSTMENTS

   The accompanying unaudited pro forma condensed statements of operations have
been prepared as if the sale of Taurus occurred on January 1, 1996 and reflects
the following adjustments:

   (a)   To eliminate the effects of Taurus' operations, net of any
         intercompany allocations which would continue.

   (b)   To record operating activities related to assets retained by the
         Company.

   (c)   To adjust interest expense for the savings resulting from the use of
         proceeds from the sale of Taurus ($42.0 million) to reduce debt
         outstanding under the Company's credit facility.  The interest rate
         used was the Company's historical rate.

   (d)   To adjust the provision for income taxes for the change in financial
         taxable income resulting from adjustments (a), (b) and (c).

   The accompanying unaudited pro forma balance sheet has been prepared as if
the sale of Taurus occurred on September 30, 1997 and reflects the following
adjustments:

   (e)   To record the sale of Taurus for $42.0 million and adjustments to the
         sales price for the (i)  pro forma working capital adjustment of
         $135,000 payable by Coda,  (ii) pro forma development capital
         expenditure adjustment of $290,000 payable by the purchaser, (iii)
         elimination of Taurus' negative cash position of approximately $1.9
         million, and (iv)  the pro forma net book value of certain immaterial
         assets transferred between Coda and Taurus resulting in an increase in
         the purchase price of $309,000.  The sale of Taurus results in a gain
         to Coda of $16.1 million.

   (f)   To record the deferred tax provision related to the gain on sale of
         Taurus.

lawsuits, claims, proceedings or investigations pending or, to the knowledge of
Coda, threatened, relating to the ownership, use, maintenance, operation of, or
conduct of business related to, any Taurus Site or assets of Taurus. For
purposes of this Agreement, "ENVIRONMENTAL LAWS" means any applicable federal,
state, or local laws, rules or regulations, common law or strict liability
provisions, and any judicial or administrative interpretations thereof,
including any judicial or administrative orders or judgments, relating to
health, safety, industrial hygiene, pollution or environmental matters in
effect as of the execution date of this Agreement.

         (r)     Undisclosed Liabilities. To the knowledge of Coda, Taurus does

interests and encumbrances, except as set forth in the Financial Statements.

back-in interests. To the knowledge of Coda, (i) Taurus' easements and

easements necessary for the operation of Taurus' business consistent with past

Taurus' business include all of the rights necessary for the use, operation and

Way material to the operation of Taurus' business.

gas gathering systems and other material improvements, fixtures and equipment
owned in whole or part by Taurus that are necessary to conduct normal
operations have been maintained in a condition adequate to conduct normal

pending or, to the knowledge of Coda, threatened criminal or civil, arising out
of any violation of, any national, state, local or other law, ordinance,
regulation, writ, injunction, order or decree, restrictive covenant, deed,
leases or restrictions relating to the Taurus Properties or the operations or
conduct of Taurus' business, except where any such violation, singly or in the
aggregate, would not have a Material Adverse Effect. To the knowledge of Coda,
no event has occurred that has resulted or would reasonably be expected to
result in a claim by, or which may entitle any officer, director, employee or
agent of Taurus to indemnification under the provisions of the Articles of
Incorporation or Bylaws (each as amended) of Taurus, any agreement of or with
Taurus, or applicable Texas law.

evidences of indebtedness for borrowed money or other instrument to which

bound, or (iii) any judgment, order, writ, injunction, or decree, of any court,
arbitrator, agency, official, authority, or other governmental body, except

         (cc)    Filings. Taurus has filed all reports required to be filed by
it with any regulatory authority to which it must report, except where such
failure, singly or in the aggregate, would not have a Material Adverse Effect,
and such filed reports have been true and correct in all material respects and
been completed in each case in accordance with applicable regulations and
requirements. None of the information supplied by Taurus for inclusion, or

written notice to CNG, and CNG shall give prompt written notice to Coda, prior
to Closing, of (i) the occurrence or non-occurrence prior to Closing of any

contained in this Agreement to be materially untrue or inaccurate, and (ii) any
failure of Coda or CNG, as the case may be, to materially comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied
by it hereunder. Coda shall give prompt written notice to CNG, and CNG shall

any third party (including any governmental agency) alleging that the consent
of such third party is or may be required in connection with the transactions
contemplated by this Agreement. After the date of this Agreement and up to
Closing, promptly after any party hereto becomes aware of any event which
changes in any material respect any representation or warranty made by such
party in this Agreement or any statement made in any schedule hereto or in any
supplemental schedule, such party shall deliver to the other parties a
supplement to the appropriate schedule (or, if no appropriate schedule exists,
a new schedule).

         5.03    Further Action; Further Assurances. Upon the terms and subject
to the conditions hereof, Coda and CNG shall each use all reasonable efforts to

counsel or by any listing or similar agreement with a securities exchange or
quotation system. Any press release or other public statement shall be mutually
agreed upon by CNG and Coda in advance of its release.

         5.05    Transfers of Certain Assets.

which are mutually acceptable to Coda and CNG.

         (b)     Upon transfer of the Excluded Taurus Assets to Coda or Coda's
nominee, all liabilities (whether arising before or after the date of transfer)
associated with the Excluded Taurus Assets shall be assumed by Coda.

         (c)     The net book value of the assets transferred pursuant to
Section 5.05(a)(i) and (a)(ii), adjusted for depreciation and capital
expenditures to the effective date of transfer, shall be applied to reduce and
increase, respectively, the outstanding balance of the long term debt due Coda
from Taurus (the "INTERCOMPANY PAYABLE").  Immediately prior to Closing, Coda
shall make a contribution to the equity of Taurus in an amount equal to the
outstanding balance of the Intercompany Payable.

         (d)     Notwithstanding anything to the contrary contained in this
Agreement, the representations and warranties set forth in Section 2.01 and the

Additional Taurus Assets for the period of time owned by Coda.

         5.06    Accounting Services. At the request of CNG, through January
31, 1998, Coda shall continue to perform, for Taurus' account, all gas
accounting services necessary or required by Taurus in connection with its
operations in the ordinary course of business, and CNG shall be responsible for
providing all data to Coda necessary or required in connection with the
performance of such services; provided that, Coda shall have no liability to
CNG, Taurus or any other party resulting from or arising out of the performance
or nonperformance of such services, except that Coda shall be liable to CNG or
Taurus resulting from or arising out of Coda's gross negligence or willful
misconduct. As compensation for such services, CNG shall pay or cause to be
paid to Coda a fee of $40,000, paid contemporaneously with the payment of the
Working Capital (as defined herein) adjustment described in Section 5.09(b).

         5.07    Files. Subject to fulfillment of any obligations arising under

Coda shall transfer or cause to be transferred to CNG any files, books, records
or other documents relating to Taurus' business which are possessed by Coda and
not already in the possession of CNG.  Coda may make and retain copies of any
of such files, books, records and documents, and CNG shall maintain or cause to
be maintained the originals or photocopies thereof within its possession and
control for a period of six years after Closing. Coda and Joint Energy
Development Investments Limited Partnership, a Delaware limited partnership
("JEDI"), shall be afforded reasonable access by CNG to such files, books,
records or other documents of Taurus.

         5.08    Cooperation in Post-Closing Matters. Coda and CNG shall each
cooperate with the other in connection with the defense by either of any suit,
action, claim or proceeding, or in connection with any audit or request for
information by any taxing authority, arising out of the conduct of Taurus'
business prior to or after the Closing. Such cooperation shall include, at the
expense of the requesting party, supplying such factual and technical
information as one party shall possess and another party may reasonably require
in connection with any such defense, audit or request for information or to
respond to discovery proceedings in any such suit, action, claim or proceeding,
and providing access to books and records as the requesting party may
reasonably require. No party, however, shall be required to so cooperate if
such cooperation would prejudice the rights of the party called upon to provide
the information.  Reimbursement of expenses hereunder shall be limited to
reasonable and necessary out-of-pocket charges and expenses, including wages
and salaries. Without limitation of the foregoing, each party





                                      -19-
<PAGE>   19
shall give the other party all reasonable cooperation to conduct an audit of
Taurus for the purpose of preparing financial statements required in connection
with any filing made by such party with the Securities and Exchange Commission,
annual reports to shareholders or similar reports which require audited
financial statements.

         5.09    Post Closing Adjustment.

         (a)     Development Capital Expenditures. For purposes of this
Agreement, the term "DEVELOPMENT CAPITAL EXPENDITURE" shall mean any capital
expenditure for gas processing plant and gathering system expansions,
extensions, enlargements, improvements or construction, including but not
limited to expenditures associated with the connection of additional supplies
of natural gas to any gathering system, but excluding expenditures associated
with maintenance, replacement or repair and related expenditures.
Notwithstanding anything to the contrary contained in this Agreement, CNG and
Acquisition "A" shall be jointly and severally liable to Coda and shall
reimburse Coda for all Development Capital Expenditures actually paid by or for
the account of Taurus after June 30, 1997 and prior to November 30, 1997,
excluding therefrom any Development Capital Expenditures (i) in excess of the
amount stated in Section 4.01(e)(iv) that are not expressly consented to by
CNG, which consent shall not be unreasonably withheld, and (ii) associated with
the Excluded Taurus Assets (the total sum of such Development Capital
Expenditures to be reimbursed to Coda is hereinafter referred to as the
"REIMBURSED CAPITAL EXPENDITURES"). As soon as practicable after the Closing
Date, Coda shall prepare and submit to CNG a statement describing and
calculating the Reimbursed Capital Expenditures. The Reimbursed Capital
Expenditures shall be reimbursed to Coda in immediately available funds
simultaneously with the payment due on the Working Capital adjustment described
in Section 5.09(b) below.

         (b)     Working Capital Adjustment. For purposes of this Agreement,
"CLOSING WORKING CAPITAL" means the Working Capital of Taurus as of November
30, 1997; "WORKING CAPITAL" means (i) current assets, determined on a basis
consistent with the Taurus Interim Financial Statements and in accordance with
GAAP, minus (ii) current liabilities, determined on a basis consistent with the
Taurus Interim Financial Statements and in accordance with GAAP (excluding all
Development Capital Expenditures, other than Development Capital Expenditures
associated with the Excluded Taurus Assets). As soon as practicable, but in no
event not later than January 29, 1998, CNG shall cause to be prepared a
calculation of the Closing Working Capital and deliver such calculation to Coda
for review. Coda shall notify CNG within ten (10) business days of receipt
thereof whether it agrees with such calculation and, if not, shall specify in
reasonable detail the points of disagreement. If any such disagreement cannot
be resolved within ten (10) business days thereafter, Coda and CNG shall
mutually agree upon a reputable firm of independent public accountants which
has not performed any services since January 1, 1997 for Coda, Taurus, or CNG
or its affiliates to resolve all points of disagreement with respect to the
Closing Working Capital. The fees of such third party accounting firm shall be
borne one-half by Coda and one-half by CNG, and all determinations made by such
firm shall be final, conclusive, and binding with respect to the calculation of
the Closing Working Capital. If the Closing Working Capital position is less
than zero, the amount by which it is less shall be paid promptly by Coda to CNG
in immediately available funds; if such Closing Working Capital position is
greater than zero, the amount by which it is greater shall be paid promptly by
CNG to Coda in immediately available funds.

         5.10    Schedules. Disclosure of any fact or item in this Agreement or
in any schedule hereto referenced to a particular section or paragraph in this
Agreement (i) shall, should the existence of the fact or item or its contents
be relevant to any other section or paragraph herein, be deemed to be disclosed
with respect to all such other sections or paragraphs of this Agreement,
whether or not an explicit cross-reference appears; and, (ii) shall not be
deemed an admission, representation or warranty as to the materiality of such
fact or item.





                                      -20-
<PAGE>   20
         5.11    Tax Matters. Coda will be responsible for any payment of, or
receive any benefit from, federal income taxes resulting from Taurus'
operations prior to Closing. Coda will be responsible for the payment of Texas
franchise taxes owed by Taurus or Coda with respect to Taurus' normal business
operations prior to Closing. CNG shall be responsible for the payment of Texas
franchise taxes, if any, owed by Holdings. CNG shall be responsible for any
Texas franchise taxes which are imposed on Taurus solely as a result of the
transactions contemplated by this Agreement or operations of Taurus subsequent
to Closing. Coda shall be responsible for any tax imposed under any other state
(excluding Texas franchise tax) and federal laws to which Coda, Taurus and/or
Holdings are subject as a result of any "gain" realized (or deemed to be
realized under the Code and corresponding provisions of state law as if Coda
had sold the Taurus Shares to Acquisition "B" in a stock sale subject to a
Section 338(h)(10) election under the Code). CNG shall be responsible for any
additional federal or state income, franchise, sales, excise or similar taxes
which Coda, Taurus or Holdings are required to pay in excess of the amounts
contemplated in the immediately preceding sentence solely as a result of the
structure of this transaction. Except as contemplated in this Section 5.11, all
remaining taxes shall be discharged by the party incurring such tax.

         5.12    Taurus Personnel. In the event CNG notifies Coda in writing at
least one business day prior to Closing that the employment of any Taurus
Dallas office employee will not be continued after Closing, Coda shall cause
Taurus to notify such individual of the termination of their employment
effective as of Closing. Coda shall, at its own cost and expense, pay severance
benefits to eligible individuals in accordance with Exhibit 1 hereto.

         5.13    Non-Competition. Coda agrees that until the second anniversary
of the Closing Date, neither it nor any of its subsidiaries shall engage or
agree to engage, either directly or indirectly, as a principal or for its own
account or solely or jointly with others, or as stockholders owning more than
ten percent (10%) in any corporation or joint stock association, in any
business that gathers, transports or processes natural gas within a thirty (30)
mile radius of the processing plants currently owned by Taurus (excluding the
Excluded Taurus Assets and excluding any gathering, transportation or
processing lines and equipment acquired in connection with any acquisition of
oil or gas properties by Coda or its subsidiaries).

         If any provision contained in this Section 5.13 shall for any reason
be held invalid, illegal or unenforceable in any respect, such invalidity,
illegality of unenforceability shall not affect any other provisions of this
Section, but this Section shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein. It is the intention of
the parties that if any of the restrictions or covenants contained herein is
held to cover a geographic area or to be for a length of time which is not
permitted by applicable law, or in any way construed to be too broad or to any
extent invalid, such provision shall not be construed to be null, void and of
no effect, but to the extent such provision would be valid or enforceable under
applicable law, a court of competent jurisdiction shall construe and interpret
or reform this Section to provide for a covenant having the maximum enforceable
geographic area, time period and other provisions (not greater than those
contained herein) as shall be valid and enforceable under such applicable law.
Coda acknowledges that CNG would be irreparably harmed by any breach of this
Section and that there would be no adequate remedy at law or in damages to
compensate CNG for any such breach. Coda agrees that CNG shall be entitled to
injunctive relief requiring specific performance by Coda of this Section, and
Coda consents to the entry thereof.

         5.14    No Negotiation. Until Closing or such time, if any, as this
Agreement is terminated pursuant to Section 8 hereof, Coda, Taurus and their
respective officers, directors, employees and agents will not, directly or
indirectly, solicit, initiate, or encourage any inquiries or proposals from,
discuss or negotiate with, provide any non-public information to, or consider
the merits of any unsolicited inquiries or proposals from any person (other
than CNG) relating to any transaction involving the sale of the





                                      -21-
<PAGE>   21
business or all or substantially all of the assets of Taurus or any of the
capital stock of Taurus, or any merger, consolidation, business combination or
similar transaction involving Taurus.

         5.15    CNG and Coda to Cause Performance. CNG agrees to take all
action necessary to cause CHC, Acquisition "A" and Acquisition "B" to perform
all of their respective agreements, covenants and obligations under this
Agreement and to consummate the transactions contemplated by this Agreement on
the terms and conditions set forth in this Agreement. CNG shall be liable for
any breach of any representation, warranty, covenant or agreement of CHC,
Acquisition "A" and Acquisition "B" and for any breach of this covenant. Coda
agrees to take all action necessary to cause Holdings to perform all of
Holdings' agreements, covenants and obligations under this Agreement and to
consummate the transaction contemplated by this Agreement on the terms and
conditions set forth in this Agreement. Coda shall be liable for any breach of
any representation, warranty, covenant and agreement of Taurus (provided that
Coda shall not be liable for post-Closing covenants and agreements of Taurus)
and Holdings and for any breach of this covenant.

         5.16    Merger. Immediately prior to Closing Coda shall have caused
Taurus Corp. to merge into and with Taurus L.P. pursuant to the terms of an
Agreement of Merger reasonably acceptable to CNG. The Certificate of Limited

                 executed and delivered by Coda and, subject to due execution

shall terminate on the second anniversary of the Closing Date; provided,
however, that the obligations under Sections 7.01 and 7.02 shall not terminate
with respect to any item as to which the person entitled to indemnification
shall have, before the expiration of such applicable period, delivered notice
pursuant to Section 7.04; and provided, further, that the indemnity for taxes
due or payable shall not terminate until the expiration of the applicable
statute of limitations.

         7.04    Notice and Opportunity to Defend.

         (a)     If any of the persons entitled to indemnification hereunder
(the "INDEMNITEE") receives notice of any claim or commencement of any action
or proceeding (an "ASSERTED LIABILITY") with respect to which another party
(the "INDEMNITOR") is or may be obligated to provide indemnification pursuant
to Sections 7.01 or 7.02 hereof, the Indemnitee shall promptly notify the
Indemnitor, describing the Asserted Liability in reasonable detail and
indicating the amount (which may be estimated) of the loss, expense, damage,
liability, or obligation that has been or may be asserted by the Indemnitee
against the Indemnitor; provided, however, that the failure to give such notice
shall not result in a loss of the Indemnitee's right to indemnification under
this Article 7 unless and to the extent such failure materially prejudices the
Indemnitor's ability to defend against the Asserted Liability.

         (b)     No settlement or compromise of an Asserted Liability may be
made by the Indemnitee without the written consent of the Indemnitor. No
settlement or compromise of an Asserted Liability may be made by Indemnitor
without the written consent of Indemnitee unless such settlement includes as an





                                      -29-
<PAGE>   29
unconditional term thereof, a full release of all Indemnitees by the claimant
or plaintiff from all liability with respect to the Asserted Liability.

         (c)     If the Indemnitor so elects, the Indemnitor, at the
Indemnitor's expense, shall assume the defense of the Asserted Liability and
shall have the right to settle or compromise the same, except that if the
Indemnitee's counsel reasonably objects to such assumption on the ground that
there may be legal defenses available to the Indemnitee that are different from
or in addition to those available to the Indemnitor, then the Indemnitee shall
have the right to employ separate counsel approved by the Indemnitor. In order
to assume such defense, the Indemnitor must notify the Indemnitee in writing of
its election to do so within ten (10) business days of receipt of notice of the
Asserted Liability from the Indemnitee; in the event the Indemnitor does not so
notify the Indemnitee within such ten (10) business day period, the Indemnitor
shall be deemed to have elected to not assume such defense.

         (d)     If the Indemnitor assumes the defense of the Asserted
Liability, the Indemnitor shall not be liable for the fees and expenses of the
Indemnitee's counsel incurred thereafter in connection with the Asserted
Liability. As to those Asserted Liabilities with respect to which the
Indemnitor does not elect to assume control or defense (i) the Indemnitee shall
afford the Indemnitor an opportunity to participate in such defense, at the
Indemnitor's own cost and expense and (ii) the Indemnitor agrees to reasonably
cooperate in such defense.

         (e)     In no event shall the Indemnitor be liable for the fees and
expenses of more than one counsel for any, some or all Indemnitees in any one
action or separate but similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, unless in the
reasonable opinion of such counsel, there is, under applicable standards of
professional conduct, a conflict on any significant issue between the positions
of any two Indemnitees.

         7.05    Insurance, Etc. Following Closing, CNG, CHC, Acquisition "A"
and Acquisition "B" shall use or cause to be used commercially reasonable
efforts, and shall cause Taurus to use commercially reasonable efforts, to (i)
file (or cause to be filed) claims under all insurance policies held by Taurus
immediately prior to the Closing Date that may be recoverable in respect of any
indemnified Losses thereunder, (ii) pursue all claims for indemnification,
contribution or other recoveries (whether for breach of contract or otherwise)
under agreements with third parties, and (iii) pursue all rights for
contribution or other recoveries against third parties afforded under
applicable law (including, but not limited to, remedies afforded under CERCLA);
provided, however, CNG, CHC, Acquisition "A" and Acquisition "B" shall not be
obligated to make out-of-pocket payments on any Loss pending resolution of any
claims for indemnity, contribution or other recoveries against third parties,
it being agreed that Coda shall make such payment and CNG, CHC, Acquisition "A"
and Acquisition "B" shall cause Taurus, Acquisition "A" or Acquisition "B" to
reimburse Coda for any indemnity payment made by it that is later recovered
from a third party. Coda (through counsel retained by Coda at Coda's expense)
shall be afforded the opportunity to consult with such insurer(s) and any
settlement with any insurer in respect of any indemnified Losses may only be
made with the consent of Coda. CNG, Acquisition "A" and Acquisition "B" shall
cause Taurus to maintain in full force and effect all existing policies of
insurance coverages currently in effect in accordance with the custom of
similarly situated companies in the same industry. In the event CNG, CHC,
Acquisition "A" or Acquisition "B" determine to cancel or not renew any of such
insurance policies pursuant to the foregoing sentence, CNG shall give Coda
written notice the earlier of twenty (20) days prior to the effective date of
such cancellation or expiration or five (5) days after receipt of a written
notice of cancellation. Coda shall be afforded the opportunity to renew any
such policy at its own cost. CNG, CHC, Acquisition "A" and Acquisition "B"
shall cooperate, and shall cause Taurus to cooperate, with Coda in respect of
the renewal or extension of such insurance or in securing a replacement policy
therefor.





                                      -30-
<PAGE>   30
         No right of subrogation shall accrue hereunder to any insurer or other
party. There shall be no third party beneficiaries of any provision of this
Section 7.06 (other than the Indemnitee under Section 7.01).

Closing Date:

         (a)     By mutual written consent of Coda and CNG;

         (b)     By Coda or CNG, if Closing has not occurred by November 25,
1997, so long as the failure to consummate the transaction contemplated by this
Agreement does not result from a breach of this Agreement by the party seeking
termination of this Agreement;

         (c)     By Coda or CNG, if a court of competent jurisdiction or
governmental, regulatory or administrative agency or commission shall have
issued an order, decree or ruling or taken any other action, in each case
permanently restraining, enjoining or otherwise prohibiting the transactions
contemplated by this Agreement;

         (d)     By CNG, if Coda breaches in any material respect any of its
agreements or covenants contained herein, and such breach is not waived or
cured within ten (10) days after written notice from CNG; provided that, if
such agreement or covenant cannot reasonably be cured within ten (10) days
after written notice, then an additional reasonable period of time shall be
permitted, not to exceed twenty (20) days, provided the breaching party is
continually and diligently pursuing such cure.

         (e)     By Coda, if CNG, CHC, Acquisition "A" or Acquisition "B"
breaches in any material respect any of its agreements or covenants contained
herein, and such breach is not waived or cured within ten (10) days after
written notice from Coda; provided that, if such agreement or covenant cannot
reasonably be cured within ten (10) days after written notice, then an
additional reasonable period of time shall be permitted, not to exceed twenty
(20) days, provided the breaching party is continually and diligently pursuing
such cure.

         (f)     By CNG, if there shall have occurred, after the execution and
delivery of this Agreement and prior to November 24, 1997, a casualty loss in
respect of the property, plant or equipment of Taurus in excess of $250,000.

         8.02    Effect of Termination. In the event of the termination of this
Agreement pursuant to Sections 8.01, this Agreement shall forthwith become void
and there shall be no liability on the part of any party hereto except (i) as
set forth in Sections 8.05 and 9.01 hereof, and (ii) nothing herein shall
relieve any party from liability for any willful breach hereof and for any
breach giving rise to a termination under Sections 8.01(d) or (e).

writing, signed by the parties hereto.

the other party hereto, (b) waive any inaccuracies in the representations and
warranties contained herein or in any document delivered pursuant hereto and

extension or waiver shall be valid and enforceable only if set forth in an
instrument in writing signed by the party to be bound thereby.

         8.05    Fees and Expenses. Except as otherwise expressly provided in
this Agreement, each party hereto agrees to pay, without right of reimbursement
from the other party, the costs incurred by it incident to the performance of
its obligations hereunder, whether or not the transactions contemplated hereby
shall be consummated, including, without limitation, those incident to the
preparation and negotiation of this Agreement, and the fees and disbursements
of counsel, accountants and consultants employed by it in connection with the
transactions contemplated hereby.

9.       MISCELLANEOUS

         9.01    Survival of Representations, Warranties, Covenants and

Notwithstanding the second sentence of this Section 9.07, Coda may, prior to
the Closing Date, and without the consent of CNG, Acquisition "A" and/or CHC
(i) convey Taurus in its entirety to JEDI or its designee, (ii) assign all of
their rights, duties, obligations and liabilities under this Agreement to JEDI

the parties hereto agree to make such modifications to this Agreement as are
reasonable and necessary in respect of such assignment.

implied, is intended to or shall confer upon any other person (other than JEDI)
any right, benefit or remedy of any nature whatsoever under or by reason of

submits to the exclusive jurisdiction of such courts for the purpose of any
such suit, action or proceeding relating to this Agreement or any related
agreement or obligation.

         Each party hereto hereby irrevocably waives any objection that it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or any agreement or obligation
delivered in connection with this Agreement, brought in the courts of the State
of Texas, County of Dallas or the United States District Court for the Northern
District of Texas, and hereby further irrevocably waives any claim that any
such suit, action or proceeding brought in any such court has been brought in
an inconvenient forum.

         9.10    Governing Law. THIS AGREEMENT IS MADE PURSUANT TO, SHALL BE
CONSTRUED UNDER, AND SHALL BE CONCLUSIVELY DEEMED FOR ALL PURPOSES TO HAVE BEEN
EXECUTED AND DELIVERED UNDER, THE SUBSTANTIVE LAWS OF THE STATE OF TEXAS
WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICT OF LAWS. THE OBLIGATIONS AND
UNDERTAKINGS OF EACH OF THE PARTIES TO THIS AGREEMENT SHALL BE PERFORMABLE IN

         9.11    Counterparts. This Agreement may be executed in one or more
counterparts, each of which when executed shall be deemed to be an original but

         9.12    Arbitration. Any and all claims, demands, causes of action,
disputes, controversies and other matters in question arising out of or
relating to this Agreement (except disputes arising under Section 5.09(b) which
shall be resolved as set forth therein), the alleged breach thereof, or in any
way relating to the subject matter of this Agreement ("CLAIMS"), even though
some or all of such Claims allegedly are extracontractual in nature, whether
such Claims sound in contract, tort or otherwise, at law or in equity, under
state or federal law, whether provided by statute or the common law, for
damages or any other relief, shall be resolved and decided exclusively by
binding arbitration pursuant to the Federal Arbitration Act in accordance with
the Commercial Arbitration Rules then in effect with the American Arbitration
Association. The arbitration proceeding shall be conducted in Dallas, Texas.
The arbitration shall be before a panel of three arbitrators. Each party to
such dispute shall select one arbitrator and the two arbitrators selected by
the parties shall select the third arbitrator. The arbitrators are authorized
to issue subpoenas for depositions and other discovery mechanisms, as well as
trial subpoenas, in accordance with the Federal Rules of Civil Procedure.
Either party may initiate a proceeding in the appropriate United States
District Court to enforce this provision. This agreement to arbitrate shall be
enforceable in either federal or state court. Judgment upon any award rendered
in any such arbitration proceeding may be entered by any federal or state court
having jurisdiction.  The enforcement of this agreement to arbitrate and all
procedural aspects of this agreement to arbitrate, including the construction
and interpretation of this agreement to arbitrate, the scope of the arbitrable
issues, allegations of waiver, delay or defenses to arbitrability, and the
rules governing the conduct of the arbitration, shall be governed by and
construed pursuant to the Federal Arbitration Act. The arbitrators shall have
no authority to award punitive (including, without limitation, any exemplary
damages, treble damages or any other penalty or punitive type of damages),
consequential, incidental or indirect damages (in tort, contract or otherwise)
under any circumstances, the parties hereby waiving their right, if any, to
recover such damages in connection with any Claims. The arbitrators shall be
entitled to award costs of the arbitration and attorney's fees as they deem
appropriate. Prior to any person instituting a Claim under this Agreement, such
person shall provide to the other party hereto a written notice specifying the
nature and basis of the Claim. The persons who are the subject of any Claim
shall be given thirty (30) days to cure any breach before any Claim is filed.





                                      -34-
<PAGE>   34
It is further agreed that prior to such Claims being submitted to the
arbitrators on such Claims, the parties to the Claims shall attempt to resolve
such Claims through non-binding mediation of such Claims for a period not in
excess of 30 days commencing after assertion of a Claim.
