ITEM 2

         Acquisition Transaction. On November 24, 1997, Continental Natural Gas,
Inc. (the "Registrant") entered into an Agreement and Plan of Merger (the
"Agreement") with Coda Energy, Inc. to acquire all of the issued and outstanding
equity interests of Taurus Energy Corp. ("Taurus"), a Texas corporation. A copy
of the Agreement is filed as Exhibit 2.1 to this Form 8-K. The Registrant closed
on its Agreement with Coda on November 25, 1997. The consideration paid to Coda
was the sum $42,000,000.00 which was negotiated in an arms length transaction.
There is no material relationship between Registrant (including its affiliates,
officers and directors) or Coda (including its affiliates, officers and
directors). The transaction was financed through an Amended and Restated Credit
Agreement (the "Loan Agreement") with ING Capital Corporation as described
below.

         In general, Taurus' activities consist of the purchase, gathering,
processing and sale of natural gas and natural gas liquids. The Registrant
intends to continue such activities under the name of Continental/Taurus Energy
Company L.P. ("Continental/Taurus L.P."). In connection with these activities,
the assets held by Taurus consisted, generally, of two separate processing
plants and related gathering systems located in North Central Texas - one system
is commonly known as the Hamlin processing plant and gathering system and the
other plant is commonly known as the Shackelford plant and gathering system. The
Shackelford gas gathering system consists of approximately 250 miles of low
pressure gathering lines and twenty-one compressor stations located in
Shackelford, Callahan, Stephens, and Throckmorton Counties, Texas. The
Shackelford gas processing plant is a 30 MMcf/D capacity refrigerated lean oil
absorption plant located near Putnam, Texas. The Hamlin gathering system
consists of approximately 500 miles of low pressure gathering lines and fourteen
compressor stations in Fisher, Stonewall, Jones, Haskell, King, Mitchell, Nolan,
Taylor, and Cottle Counties, Texas. The Hamlin gas processing plant is a 20
MMcf/D propane refrigeration plant (including an associated 10 MMcf/d cryogenic
turbo expander system) and is located near Hamlin, Texas. Together the
Shackelford and Hamlin plants are capable of extracting 290,000 gallons per day
of natural gas liquids.

         A majority of the natural gas processed at the Hamlin Plant and
approximately 80% of the natural gas processed at the Shackelford Plant are
dedicated to such plants under percentage of proceeds contracts. Under a
percentage of proceeds contract, the processor (in this case, Continental/Taurus
L.P.) pays each producer a percentage of the net sales price for: (i) natural
gas and (ii) natural gas liquids. In turn, the processor retains a percentage of
the net sales price for natural gas and natural gas liquids. From the
processor's share of proceeds, it is obligated to pay its operating costs for
its plants and gathering systems. Consequently, profitability of the Shackelford
and Hamlin plants and gathering systems will be determined in large part by the
operating efficiency which Continental/Taurus L.P. is able to achieve.


                                        2
<PAGE>   3

         The Registrant has not previously conducted operations in the area of
the Shackelford and Hamlin systems. The acquisition of Taurus is consistent with
the Registrant's strategy to expand into new operating areas.

         Audited financial statements for Taurus are, as yet, unavailable. The
Registrant will file an amendment to this Form 8-K to provide audited financials
as required by Item 7(a) and 7(b) of Form 8-K within sixty (60) days following
the date this Form 8-K is required to be filed.

         Loan Transaction. In connection with closing on the Agreement, the
Registrant entered into an Amended and Restated Loan Agreement with ING Capital
Corp. (the "Loan Agreement"). Under the terms of the Loan Agreement, the
Registrant's term loan facility was increased from forty million
($40,000,000.00) to seventy-five million dollars ($75,000,000.00), and the
Registrant's revolving credit facility remained at twenty-five million dollars
($25,000,000.00). In addition, the assets of Continental/Taurus L.P. were
mortgaged under the Loan Agreement. A copy of the Loan Agreement is filed as
Exhibit 10.1 to this Form 8-K. The Registrant closed on the Loan Agreement on
November 25, 1997, and borrowed the full amount ($75,000,000.00) of the term
loan facility. Proceeds of the term loan facility were used as follows: $42
million for purchase of Taurus; $30.25 million to refinance the Registrant's
existing term loan facility and outstanding amounts under Registrant's existing
revolving credit facility; and $2.74 million for general corporate purposes
(including working capital and expenses related to the Loan Agreement).

Interest rates under both the revolving facility and term facility are variable,
at the Registrant's election, at (i) up to 3/4 of a percent (depending on the
Registrant's financial performance) above the greater of (x) the arithmetic
average of the prime rates announced by Chase Manhattan Bank, City Bank, N.A.
and Morgan Guaranty Trust Company of New York or (y) the federal funds rate as
published by the Federal Reserve Bank of New York plus 1/2%; or (ii) 1.375% to
2.5%, depending upon the Registrant's financial performance above the London
Interbank Offered Rate (LIBOR). Principal repayments under the term facility
will begin on March 31, 1998. Maturity of the term loan facility was extended
from July 31, 2001 to December 31, 2002.



ITEM 5   OTHER EVENTS.

In connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995, the Registrant is hereby filing cautionary
statements identifying important factors that could cause the Registrant's
actual results to differ materially from those projected in forward looking
statements of the Registrant made by, or on behalf of, the Registrant.

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.

         (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,

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





                                       18
<PAGE>   19
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.

         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





                                       19
<PAGE>   20
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 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
Partnership and Agreement of Limited Partnership for Taurus L.P. shall be in
form and substance reasonably acceptable to CNG.

         satisfactory to CNG, to the effect that:

                          (A)     (1) Coda is a corporation duly incorporated,
                 validly existing and in good standing under the laws of the

                 duly authorized and validly issued, fully paid and
                 non-assessable and, to the knowledge of such counsel after due
                 investigation, have not been issued in violation of any

                 consist solely of the Partnership Interests; the Partnership

                 rights and there is no option, warrant, call, subscription or
                 other agreement relating to the Partnership Interests;

                 executed and delivered by Coda and, subject to due execution
                 by CNG and Acquisition "A," constitutes a legal, valid and
                 binding agreement of Coda and is enforceable against Coda (and
                 its successors and assigns) in accordance with its terms,
                 subject to appropriate exceptions for bankruptcy and

                 or violate any provisions of the charter or bylaws, as
                 amended, of Coda, or any statute, rule, or regulation
                 applicable to Coda or, to the knowledge of such counsel after

         satisfaction by Coda of any condition set forth herein, or to

         7.03    Limitation on Indemnity.

         (a)     Notwithstanding anything to the contrary contained in this
Agreement, for purposes of the indemnity of CNG, CHC, Acquisition "A" and
Acquisition "B" by Coda provided for in Section 7.01:  (i) the aggregate of all
Losses as hereinabove defined (other than Losses arising from a breach of the
representation in Section 2.01(q) (an "ENVIRONMENTAL LOSS")) (net of income tax
effects and net of any recoveries from third parties (including recoveries
under insurance policies) as described in Section 7.05) shall not exceed
$3,000,000; and (ii) the indemnity in Section 7.01 shall be subject to
deductibles for certain Losses (net of income tax effects and net of any
recoveries from third parties (including recoveries under insurance policies)
as described in Section 7.05) as set forth below.  Notwithstanding anything to
the contrary contained in this Agreement, for purposes of the indemnity of CNG,
CHC, Acquisition "A" and Acquisition "B" by Coda provided for in Section 7.01
with respect to any Environmental Loss: (x) the aggregate of all Environmental
Losses (net of income tax effects and net of any recoveries from third parties
(including recoveries under insurance policies) as described in Section 7.05)
shall not exceed $5,000,000; (y) the indemnity in Section 7.01 shall be subject
to deductibles for Environmental Losses arising from a breach of the
representation in Section 2.01(q) (net of income tax effects and net of any
recoveries from third parties (including recoveries under insurance policies)
as described in Section 7.05) as set forth below; and (z) Environmental Losses
shall not be recoverable from the breach of any other representation or
warranty contained in Section 2.01. The deductibles for those Losses other than
Environmental Losses (net of income tax effects and net of any recoveries from
third parties (including recoveries under insurance policies) as described in
Section 7.05) described in clause (ii) above shall be $100,000, in the
aggregate, for breach of each representation and warranty in Section 2.01 which
are to be construed, for purposes of such deductibles, as follows: (A) Sections
2.01(g), (i), (l) and (aa) shall each be construed as a single representation
and warranty, (B) Sections 2.01(h), (j) and (r) read together as if they were
one representation and warranty, (C) Sections 2.01(m), (u) and (cc) read
together as if they were one representation and warranty, and (D) all other
subsections of Section 2.01 read together as if they were one representation
and warranty.  The deductible for Environmental Losses (net of income tax
effects and net of any recoveries from third parties (including recoveries
under insurance policies) as described in Section 7.05) as described in clause
(y) above shall be $50,000 in the aggregate.  With respect to the deductibles
set forth in the immediately preceding sentence, Coda may not assert that any
single occurrence (or closely related set of occurrences) is subject to more
than one deductible.  Except as described on Schedule 7.03(a), Coda will not be
responsible for any indemnification in respect of any claim for a breach by
Coda or Holdings of any representation, warranty, covenant or agreement herein
that is known to CNG, CHC, Acquisition "A" and Acquisition "B" at the date of
this Agreement.  The limitations on indemnity contained in clauses (i) and (ii)
of this Section 7.03 shall not apply to breaches of the representation
contained in Section 2.01(k) and the agreement of Coda set forth in Section
5.11 (provided, however, any breach thereof may only relate to the tax period
ending on or prior to the Closing Date as set forth in Section 5.11).  The
indemnity provided in Section 7.01, as hereinabove limited, shall be the sole
remedy of CNG, CHC, Acquisition "A" and Acquisition "B" against Coda with
respect to any breach or inaccuracy of any representation or warranty of Coda
contained in Section 2.01 of this Agreement.

         (b)     Notwithstanding anything to the contrary contained in this
Agreement, for purposes of the indemnity of Coda by CNG, CHC, Acquisition "A"
and Acquisition "B" provided for in Section 7.02:  (i) the aggregate of all
Losses as hereinabove defined (net of income tax effects and net of any
recoveries from third parties (including recoveries under insurance policies)
as described in Section 7.02) shall not exceed $3,000,000; (ii) such indemnity
shall only be made once the aggregate of all Losses under Section 7.02 exceed
$300,000, (iii) the limits on indemnity contained in clauses (i) and (ii) of
this Section 7.03(b) shall not apply to the indemnity contained in Section
7.02(iii) and the agreement of CNG set forth in Section 5.11; and (iv) the
indemnity provided in Section 7.02, as hereinabove limited, shall be the sole
remedy of Coda (or its affiliates) against CNG, CHC, Acquisition "A" and
Acquisition "B" with respect to any breach or inaccuracy of any representation
or  warranty of CNG, CHC, Acquisition "A" and Acquisition "B" contained in
Section 3.01 of this Agreement.





                                       27
<PAGE>   28
         (c)     Notwithstanding anything to the contrary contained herein, the
indemnity and hold harmless obligations provided for in Sections 7.01 and 7.02
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
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





                                       28
<PAGE>   29
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.

         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).

8.       TERMINATION, AMENDMENT AND WAIVER

         8.01    Termination.  This Agreement may be terminated and the

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

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.

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.

         8.04    Waiver.  At any time prior to Closing, any party hereto may

of the other party hereto, (b) waive any inaccuracies in the representations

herein; provided that, any such 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

preparation and negotiation of this Agreement, and the fees and disbursements
of counsel, accountants and consultants employed by it in connection with the

         to apply thereto), and the length of the applicable Interest Period;
         and

                   (ii) be received by Agent not later than 10:00 a.m., New
         York, New York time, on (A) the day on which any such Base Rate Loans
         are to be made, or (B) the third Business Day preceding the day on
         which any such Eurodollar Loans are to be made.

Each such written request or confirmation must be made in the form and
substance of the "Borrowing Notice" attached hereto as Exhibit C-1, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Borrower as to the matters which are
required to be set out in such written confirmation. Upon receipt of any such
Borrowing Notice, Agent shall give each Revolving Credit Lender prompt notice
of the terms thereof. If all conditions precedent to such new Revolving Credit
Loans have been met, each Revolving Credit Lender will on the date requested
promptly remit to Agent's account in New York, New York the amount of such
Revolving Credit Lender's new Revolving Credit Loan in immediately available
funds, and upon receipt of such funds, unless to its actual knowledge any
conditions precedent to such Revolving Credit Loans have been neither met nor
waived as provided herein, Agent shall promptly make such Revolving Credit
Loans available to Borrower. Unless Agent shall have received prompt notice
from a Revolving Credit Lender that such Revolving Credit Lender will not make
available to Agent such Revolving Credit Lender's new Revolving Credit Loan,
Agent may in its discretion assume that such Revolving Credit Lender has made
such Revolving Credit Loan available to Agent in accordance with this section
and Agent may if it chooses, in reliance upon such assumption, make such
Revolving Credit Loan available to Borrower. If and to the extent such
Revolving Credit Lender shall not so make its new Revolving Credit Loan
available to Agent, such Revolving Credit Lender and Borrower severally agree
to pay or repay to Agent within three days after demand the amount of such
Revolving Credit Loan together with interest thereon, for each day from the
date such amount was made available to Borrower until the date such amount is
paid or repaid to Agent, with interest at (i) the Federal Funds Rate, if such


                                       19

<PAGE>   25



Revolving Credit Lender is making such payment and (ii) the interest rate
applicable at the time to the other new Revolving Credit Loans made on such
date, if Borrower is making such repayment. If neither such Revolving Credit
Lender nor Borrower pay or repay to Agent such amount within such three-day
period, Agent shall in addition to such amount be entitled to recover from such
Revolving Credit Lender and from Borrower, on demand, interest thereon at the
Default Rate, calculated from the date such amount was made available to
Borrower. The failure of any Revolving Credit Lender to make any new Revolving
Credit Loan to be made by it hereunder shall not relieve any other Revolving
Credit Lender of its obligation hereunder, if any, to make its new Revolving
Credit Loan, but no Revolving Credit Lender shall be responsible for the
failure of any other Revolving Credit Lender to make any new Revolving Credit
Loan to be made by such other Revolving Credit Lender.

         (b) Requesting the Term Loans. Before the Term Loans are made,
Borrower must give Agent a written request therefor in the form and substance
of the "Request for Term Loans" attached hereto as Exhibit C-2, duly completed.
If all conditions precedent to such Term Loans have been met, each Term Lender
will on the date requested promptly remit to Agent's account in New York, New
York the amount of such Term Lender's Term Loan in immediately available funds,
and upon receipt of such funds, unless to its actual knowledge any conditions
precedent to such Term Loans have been neither met nor waived as provided
herein, Agent shall promptly make such Term Loans available to Borrower. The
Request for Term Loans shall be irrevocable and binding on Borrower. Unless
Agent shall have received prompt notice from a Term Lender that such Term
Lender will not make available to Agent such Term Lender's new Term Loan, Agent
may in its discretion assume that such Term Lender has made such Term Loan
available to Agent in accordance with this section and Agent may if it chooses,
in reliance upon such assumption, make such Term Loan available to Borrower. If
and to the extent such Term Lender shall not so make its new Term Loan
available to Agent, such Term Lender and Borrower severally agree to pay or
repay to Agent within three days after demand the amount of such Term Loan
together with interest thereon, for each day from the date such amount was made
available to Borrower until the date such amount is paid or repaid to Agent,
with interest at (i) the Federal Funds Rate, if such Term Lender is making such
payment and (ii) the interest rate applicable at the time to the other new Term
Loans made on such date, if Borrower is making such repayment. If neither such
Term Lender nor Borrower pay or repay to Agent such amount within such
three-day period, Agent shall in addition to such amount be entitled to recover
from such Term Lender and from Borrower, on demand, interest thereon at the
Default Rate, calculated from the date such amount was made available to
Borrower. The failure of any Term Lender to make any new Term Loan to be made
by it hereunder shall not relieve any other Term Lender of its obligation
hereunder, if any, to make its new Term Loan, but no Term Lender shall be
responsible for the failure of any other Term Lender to make any new Term Loan
to be made by such other Term Lender.

         (c) Loans Refinancing Existing Indebtedness under Original Agreement.
The Term Loan to refinance loans under the Original Agreement shall be a
Eurodollar Loan with an Interest Period of 36 days.


                                       20

         Section 2.3. Continuations and Conversions of Existing Loans. Borrower
may make the following elections with respect to Loans from time to time
outstanding: to convert Base Rate Loans to Eurodollar Loans, to convert
Eurodollar Loans to Base Rate Loans on the last day of the Interest Period
applicable thereto, or to continue Eurodollar Loans beyond the expiration of
such Interest Period by designating a new Interest Period to take effect at the
time of such expiration. In making such elections, Borrower may combine
existing Loans made pursuant to separate Borrowings into one new Borrowing or
divide existing Loans made pursuant to one Borrowing into separate new
Borrowings. To make any such election, Borrower must give to Agent written
notice (or telephonic notice promptly confirmed in writing) of any such
conversion or continuation of existing Loans, with a separate notice given for
each new Borrowing. Each such notice constitutes a "Continuation/Conversion
Notice" hereunder and must:

                  (a)  specify the existing Loans which are to be continued or 
         converted;

                  (b) specify (i) the aggregate amount of any Borrowing of Base
         Rate Loans into which such existing Loans are to be continued or
         converted and the date on which such continuation or conversion is to
         occur, or (ii) the aggregate amount of any Borrowing of Eurodollar
         Loans into which such existing Loans are to be continued or converted,
         the date on which such continuation or conversion is to occur (which
         shall be the first day of the Interest Period which is to apply to
         such Eurodollar Loans), and the length of the applicable Interest
         Period; and

                  (c) be received by Agent not later than 10:00 a.m., New York,
         New York time, on (i) the day on which any such continuation or
         conversion to Base Rate Loans is to occur, or (ii) the third Business
         Day preceding the day on which any such continuation or conversion to
         Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and
substance of the "Continuation/Conversion Notice" attached hereto as Exhibit C,
duly completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Borrower as to the matters which are
required to be set out in such written confirmation. Upon receipt of any such
Borrowing Notice, Agent shall give each Lender prompt notice of the terms
thereof. Each Borrowing Notice shall be irrevocable and binding on Borrower.
During the continuance of any Default, Borrower may not make any election to
convert existing Loans into Eurodollar Loans or continue existing Loans as
Eurodollar Loans. If (due to the existence of a Default or for any other
reason) Borrower fails to timely and properly give any notice of continuation
or conversion with respect to a Borrowing of existing Eurodollar Loans at least
three days prior to the end of the Interest Period applicable thereto, such
Eurodollar Loans shall automatically be converted into Base Rate Loans at the
end of such Interest Period. No new funds shall be repaid by Borrower or
advanced by any Lender in connection with any continuation or conversion of
existing Loans pursuant to this section, and no such continuation or conversion
shall be deemed to be a new advance of funds for any purpose; such
continuations and conversions merely constitute a change in the interest rate
applicable to already outstanding Loans.

         Section 2.4. Use of Proceeds. Borrower shall use all Term Loans to
refinance the existing indebtedness under the Original Agreement and for
general other general business purposes, and $41,580,000 of the proceeds of the
Term Loans will be contributed by Borrower as capital to C/T Holdings, and then
contributed by C/T Holdings as capital to C/T Acquisition, and $420,000 of the
proceeds of the Term Loans will be contributed by Borrower as capital to CHC,
to finance the acquisition of the partnership interests in Taurus LP pursuant
to the Acquisition Documents. Borrower shall use all Revolving Credit Loans to
finance capital expenditures, to refinance Matured LC Obligations, and to
provide working capital for its operations and for other general business
purposes. Borrower shall use all Letters of Credit for its general business
purposes. In no event shall the funds from any Loan or any Letter of Credit be
used directly or indirectly by any Person for personal, family, household or
agricultural purposes or for the purpose, whether immediate, incidental or
ultimate, of purchasing, acquiring or carrying any "margin stock" or any
"margin securities" (as such terms are defined respectively in Regulation U and
Regulation G promulgated by the Board of Governors of the Federal Reserve
System) or to extend credit to others directly or indirectly for the purpose of
purchasing or carrying any such margin stock or margin securities. Borrower
represents and warrants that Borrower is not engaged principally, or as one of
Borrower's important activities, in the business of extending credit to others
for the purpose of purchasing or carrying such margin stock or margin
securities.

         Section 2.5.  Fees.

         (a) Revolving Credit Commitment Fee. In consideration of each
Revolving Credit Lender's commitment to make Revolving Credit Loans, Borrower
will pay to Agent for the account of each Revolving Credit Lender a commitment
fee determined on a daily basis by applying a rate of three-eighths percent
(0.375%) per annum to such Revolving Credit Lender's Revolving Credit
Percentage Share of the unused portion of the Revolving Credit Maximum Loan
Amount on each day during the Revolving Credit Commitment Period, determined
for each such day by deducting from the amount of the Revolving Credit Maximum
Loan Amount at the end of such day the Revolving Credit Facility Usage. This
commitment fee shall be due and payable in arrears on the last day of each
March, June, September and December and at the end of the Revolving Credit
Commitment Period.

         (b) Agent's Fees. In addition to all other amounts due to Agent under
the Loan Documents, Borrower will pay fees to Agent as described in a letter
agreement of even date herewith between Agent and Borrower.

         Section 2.6.  Optional Prepayments.  Borrower may, upon five Business 
Days' notice to Agent (who shall upon receipt of such notice promptly notify
each Lender), from time to time and without premium or penalty prepay the Notes
(and, so long as no Default has occurred and is continuing, Borrower may
designate such prepayment to be applied to the Revolving Credit Notes or the
Term Notes), in whole or in part, so long as the aggregate amounts of all
partial prepayments of principal on the Notes equals $100,000 or any higher
integral multiple of $100,000, so long as Borrower does not prepay any
Eurodollar Loan, and so long as Borrower does not make any prepayments which
would reduce the unpaid principal


                                       22

<PAGE>   28



balance of the Loans to less than $100,000 without first either (a) terminating
this Agreement or (b) providing assurance satisfactory to Agent in its
discretion that Lenders' legal rights under the Loan Documents are in no way
affected by such reduction. Each partial prepayment of the principal of the
Term Notes shall be applied to the regular installments of principal due
thereunder in the inverse order of their maturities. Each prepayment of
principal under this section shall be accompanied by all interest then accrued
and unpaid on the principal so prepaid. Any principal or interest prepaid
pursuant to this section shall be in addition to, and not in lieu of, all
payments otherwise required to be paid under the Loan Documents at the time of
such prepayment.

         Section 2.7.  Mandatory Prepayment of Revolving Credit Loans and Term 
Loans; Payment of Term Loans.

         (a) Mandatory Prepayment of Revolving Credit Loans. If at any time the
Revolving Credit Facility Usage is in excess of the Borrowing Base (such excess
being herein called a "Borrowing Base Deficiency"), Borrower shall, within
fifteen days after Agent gives notice of such fact to Borrower prepay the
principal of the Revolving Credit Loans in an aggregate amount at least equal
to such Borrowing Base Deficiency (or, if the Revolving Credit Loans have been
paid in full, deliver LC Collateral to LC Issuer as required under Section
2.15(a)). Each prepayment of principal under this subsection shall be
accompanied by all interest then accrued and unpaid on the principal so
prepaid. Any principal or interest prepaid pursuant to this subsection shall be
in addition to, and not in lieu of, all payments otherwise required to be paid
under the Loan Documents at the time of such prepayment.

         (b) Mandatory Prepayment of Term Loans. Following the one-year
anniversary hereof, Borrower shall prepay the principal of the Term Loans on
the forty-fifth day of each Fiscal Quarter, commencing February 15, 1999 in an
amount equal to thirty-five percent (35%) of Borrower's Consolidated Gross
Operating Cash Flow for the preceding Fiscal Quarter, to be applied to the
regular installments of principal due thereunder in the inverse order of their
maturities. As used herein, "Consolidated Gross Operating Cash Flow" means, for
any Fiscal Quarter, Borrower's Consolidated net cash provided by operating
activities (excluding changes in operating assets and liabilities) as reported
on Borrower's quarterly statement of cash flows for such Fiscal Quarter
delivered pursuant to Section 6.2(b), minus (i) capital expenditures pursuant
to and as set forth in the most recent budget delivered pursuant to Section
6.2(d), and (ii) scheduled Term Loan principal payments during such Fiscal
Quarter. In no event shall net cash provided or used by investing activities or
financing activities be included in the determination of Consolidated Gross
Operating Cash Flow.

         (c) Repayment of Term Loans. Borrower shall repay the principal of the
Term Loans in installments on the last day of each March, June, September and
December, commencing March 31, 1998, with the final installment being due and
payable on or before December 31, 2002. Each such installment shall be the
lesser of (i) the remaining outstanding principal of the Term Loans on such
date or (ii) the following amounts:

provided, that in the event the principal amount advanced on the Term Loans is
less than $75,000,000, then each amount set forth above shall be reduced by
multiplying such amount by the original principal amount of the Term Loans
divided by $75,000,000. In any event all unpaid principal and interest on the
Term Notes shall be due and payable in full on the final maturity of December
31, 2002.

         Section 2.8.  Initial Borrowing Base.  During the period from the date 
hereof to the first redetermination date the Borrowing Base shall be
$25,000,000.

         Section 2.9.  Subsequent Determinations of Borrowing Base. Promptly
after receiving any Borrowing Notice, Revolving Credit Lenders shall, based
upon the most recent Borrowing Base Report delivered to Agent and each
Revolving Credit Lender pursuant to Section 6.2(e) hereof or in connection with
such Borrowing Notice, and such other information, reports and data available
to Revolving Credit Lenders at the time in question, redetermine the Borrowing
Base to remain in effect until the next such redetermination. The amount so
redetermined shall be equal to eighty percent (80%) of Eligible Receivables. In
the event Agent and each Revolving Credit Lender have not received an
appropriately completed Borrowing Base Report (with all attachments) within the
time period specified therein, Revolving Credit Lenders shall have no
obligation to redetermine the Borrowing Base or to make any additional
Revolving Credit Loans until such time as Revolving Credit Lenders shall have
received such information.

         Section 2.10. Letters of Credit. Subject to the terms and conditions
hereof, Borrower may during the Revolving Credit Commitment Period request LC
Issuer to issue one or more Letters of Credit, provided that, after taking such
Letter of Credit into account:



                                       24

<PAGE>   30

                  (a) the Revolving Credit Facility Usage does not exceed the
         Borrowing Base at such time; and

                  (b) the aggregate amount of LC Obligations at such time does
         not exceed $18,000,000; and

                  (c) the expiration date of such Letter of Credit is prior to
         the end of the Revolving Credit Commitment Period; and

                  (d) such Letter of Credit is to be used for general business
         purposes of Borrower;

                  (e) such Letter of Credit is not directly or indirectly used
         to assure payment of or otherwise support any Indebtedness of any
         Person other than Indebtedness of any Restricted Person;

                  (f) the issuance of such Letter of Credit will be in
         compliance with all applicable governmental restrictions, policies,
         and guidelines and will not subject LC Issuer to any cost which is
         note reimbursable under Article III;

                  (g) the form and terms of such Letter of Credit are
         acceptable to LC Issuer in its sole and absolute discretion; and

                  (h) all other conditions in this Agreement to the issuance of
         such Letter of Credit have been satisfied.

LC Issuer will honor any such request if the foregoing conditions (a) through
(h) (in the following Section 2.11 called the "LC Conditions") have been met as
of the date of issuance of such Letter of Credit. LC Issuer may choose to honor
any such request for any other Letter of Credit but has no obligation to do so
and may refuse to issue any other requested Letter of Credit for any reason
which LC Issuer in its sole discretion deems relevant.

         Section 2.11. Requesting Letters of Credit. Borrower must make written
application for any Letter of Credit at least one Business Day before the date
on which Borrower desires for LC Issuer to issue such Letter of Credit. By
making any such written application Borrower shall be deemed to have
represented and warranted that the LC Conditions described in Section 2.10 will
be met as of the date of issuance of such Letter of Credit. Each such written
application for a Letter of Credit must be made in writing in the form and
substance of Exhibit G, the terms and provisions of which are hereby
incorporated herein by reference (or in such other form as may mutually be
agreed upon by LC Issuer and Borrower). Two Business Days after the LC
Conditions for a Letter of Credit have been met as described in Section 2.10
(or if LC Issuer otherwise desires to issue such Letter of Credit), LC Issuer
will issue such Letter of Credit at LC Issuer's office in New York, New York.
If any provisions of any LC Application conflict with any provisions of this
Agreement, the provisions of this Agreement shall govern and control.

         Section 2.12.  Reimbursement and Participations.

         (a) Reimbursement by Borrower. Each Matured LC Obligation shall
constitute a loan by LC Issuer to Borrower. Borrower promises to pay to LC
Issuer, or to LC Issuer's order, on demand, the full amount of each Matured LC
Obligation, unless funded under Section 2.12(b) hereof, together with interest
thereon at the Default Rate.

         (b) Revolving Credit Loans Upon Letter of Credit Drawings. If the
beneficiary of any Letter of Credit makes a draft or other demand for payment
thereunder, then Borrower shall be deemed to have requested Revolving Credit
Lenders to make Revolving Credit Loans to Borrower on the date such draft or
demand is to be paid in the amount of such draft or demand. If all conditions
precedent to such Revolving Credit Loans shall be satisfied as of the date on
which such Revolving Credit Loans are to be made, Revolving Credit Lenders
shall make such Revolving Credit Loans pursuant to Section 2.1(a) concurrently
with LC Issuer's payment of such draft or demand, and such Revolving Credit
Loans shall be immediately used by LC Issuer to repay the amount of the
resulting Matured LC Obligation. For the purposes of the first sentence of
Section 2.1 the amount of such Revolving Credit Loans shall be considered but
the amount of the Matured LC Obligation to be concurrently paid by such
Revolving Credit Loans shall not be considered.

         (c) Participation by Revolving Credit Lenders. LC Issuer irrevocably
agrees to grant and hereby grants to each Revolving Credit Lender, and -- to
induce LC Issuer to issue Letters of Credit hereunder -- each Revolving Credit
Lender irrevocably agrees to accept and purchase and hereby accepts and
purchases from LC Issuer, on the terms and conditions hereinafter stated and
for such Revolving Credit Lender's own account and risk an undivided interest
equal to such Revolving Credit Lender's Revolving Credit Lender's Revolving
Credit Percentage Share of LC Issuer's obligations and rights under each Letter
of Credit issued hereunder and the amount of each Matured LC Obligation paid by
LC Issuer thereunder. Each Revolving Credit Lender unconditionally and
irrevocably agrees with LC Issuer that, if a Matured LC Obligation is paid
under any Letter of Credit for which LC Issuer is not reimbursed in full by
Borrower in accordance with the terms of this Agreement and the related LC
Application (including any reimbursement by means of concurrent Revolving
Credit Loans or by the application of LC Collateral), such Revolving Credit
Lender shall (in all circumstances and without set-off or counterclaim) pay to
LC Issuer on demand, in immediately available funds at LC Issuer's address for
notices hereunder, such Revolving Credit Lender's Revolving Credit Percentage
Share of such Matured LC Obligation (or any portion thereof which has not been
reimbursed by Borrower). Each Revolving Credit Lender's obligation to pay LC
Issuer pursuant to the terms of this subsection is irrevocable and
unconditional. If any amount required to be paid by any Revolving Credit Lender
to LC Issuer pursuant to this subsection is paid by such Revolving Credit
Lender to LC Issuer within three Business Days after the date such payment


                                       26

<PAGE>   32



is due, LC Issuer shall in addition to such amount be entitled to recover from
such Revolving Credit Lender, on demand, interest thereon calculated from such
due date at the Federal Funds Rate. If any amount required to be paid by any
Revolving Credit Lender to LC Issuer pursuant to this subsection is not paid by
such Revolving Credit Lender to LC Issuer within three Business Days after the
date such payment is due, LC Issuer shall in addition to such amount be
entitled to recover from such Revolving Credit Lender, on demand, interest
thereon calculated from such due date at the Default Rate.

         (d) Distributions to Participants. Whenever LC Issuer has in
accordance with this section received from any Revolving Credit Lender payment
of such Revolving Credit Lender's Revolving Credit Percentage Share of any
Matured LC Obligation, if LC Issuer thereafter receives any payment of such
Matured LC Obligation or any payment of interest thereon (whether directly from
Borrower or by application of LC Collateral or otherwise, and excluding only
interest for any period prior to LC Issuer's demand that such Revolving Credit
Lender make such payment of its Revolving Credit Percentage Share), LC Issuer
will distribute to such Revolving Credit Lender its Revolving Credit Percentage
Share of the amounts so received by LC Issuer; provided, however, that if any
such payment received by LC Issuer must thereafter be returned by LC Issuer,
such Revolving Credit Lender shall return to LC Issuer the portion thereof
which LC Issuer has previously distributed to it.

         (e) Calculations. A written advice setting forth in reasonable detail
the amounts owing under this section, submitted by LC Issuer to Borrower or any
Revolving Credit Lender from time to time, shall be conclusive, absent
demonstrable error, as to the amounts thereof.

         Section 2.13. Letter of Credit Fees. In consideration of LC Issuer's
issuance of any Letter of Credit, Borrower agrees to pay to Agent, for the
account of all Revolving Credit Lenders in accordance with their respective
Revolving Credit Percentage Shares, a letter of credit issuance fee at a rate
equal to the lesser of (a) one and one-half percent (1.5%) per annum and (b)
the Eurodollar Rate Margin per annum; provided that such fee shall not be less
than $500. Each such fee will be calculated based on the term and face amount
of such Letter of Credit and the above applicable rate and will be payable
quarterly in arrears. In addition, Borrower will pay to LC Issuer a minimum
administrative issuance fee of $100 for each Letter of Credit and an
administrative drawing fee of $300 upon any drawing under a Letter of Credit.

         Section 2.14.  No Duty to Inquire.

         (a) Drafts and Demands. LC Issuer is authorized and instructed to
accept and pay drafts and demands for payment under any Letter of Credit
without requiring, and without responsibility for, any determination as to the
existence of any event giving rise to said draft, either at the time of
acceptance of payment or thereafter. LC Issuer is under no duty to determine
the proper identity of anyone presenting such a draft or making such a demand
(whether by tested telex or otherwise) as the officer, representative or agent
of any beneficiary under any Letter of Credit, and payment by LC Issuer to any
such beneficiary when requested by any such purported officer, representative
or agent is hereby authorized and approved. Borrower agrees to hold LC Issuer
and each other Bank Party harmless and indemnified against any liability or
claim in connection with or arising out of the subject matter of this section,
WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN
ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR
OMISSION OF ANY KIND BY ANY


                                       27

<PAGE>   33



BANK PARTY, provided only that no Bank Party shall be entitled to
indemnification for that portion, if any, of any liability or claim which is
proximately caused by its own individual gross negligence or willful
misconduct.

         (b) Extension of Maturity. If the maturity of any Letter of Credit is
extended by its terms or by Law or governmental action, if any extension of the
maturity or time for presentation of drafts or any other modification of the
terms of any Letter of Credit is made at the request of any Restricted Person,
or if the amount of any Letter of Credit is increased at the request of any
Restricted Person, this Agreement shall be binding upon all Restricted Persons
with respect to such Letter of Credit as so extended, increased or otherwise
modified, with respect to drafts and property covered thereby, and with respect
to any action taken by LC Issuer, LC Issuer's correspondents, or any Bank Party
in accordance with such extension, increase or other modification.

         (c) Transferees of Letters of Credit. If any Letter of Credit provides
that it is transferable, LC Issuer shall have no duty to determine the proper
identity of anyone appearing as transferee of such Letter of Credit, nor shall
LC Issuer be charged with responsibility of any nature or character for the
validity or correctness of any transfer or successive transfers, and payment by
LC Issuer to any purported transferee or transferees as determined by LC Issuer
is hereby authorized and approved, and Borrower further agrees to hold LC
Issuer and each other Bank Party harmless and indemnified against any liability
or claim in connection with or arising out of the foregoing, WHICH INDEMNITY
SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY
EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY
KIND BY ANY BANK PARTY, provided only that no Bank Party shall be entitled to
indemnification for that portion, if any, of any liability or claim which is
proximately caused by its own individual gross negligence or willful
misconduct.

         Section 2.15.  LC Collateral.

         (a) LC Obligations in Excess of Borrowing Base. If, after the making
of all mandatory prepayments required under Section 2.7(a), the outstanding LC
Obligations will exceed the Borrowing Base, then in addition to prepayment of
the entire principal balance of the Revolving Credit Loans Borrower will
immediately pay to LC Issuer an amount equal to such excess. LC Issuer will
hold such amount as security for the remaining LC Obligations (all such amounts
held as security for LC Obligations being herein collectively called "LC
Collateral") until such LC Obligations become Matured LC Obligations, at which
time such LC Collateral may be applied to such Matured LC Obligations. So long
as no Default has occurred and is continuing, if such LC Obligations shall
expire or otherwise terminate without a drawing or other demand for payment, or
if the Borrowing Base shall increase such that the Borrowing Base exceeds the
Revolving Credit Facility Usage, LC Collateral in an amount equal to such
expired or terminated and undrawn LC Obligation shall be returned to Borrower.
Neither this subsection nor the following subsection shall, however, limit or
impair any rights which LC Issuer may have under any other document or
agreement relating to any Letter of


                                       28

<PAGE>   34



Credit or LC Obligation, including any LC Application, or any rights which any
Bank Party may have to otherwise apply any payments by Borrower and any LC
Collateral under Section 3.1.

         (b) Acceleration of LC Obligations. If the Obligations or any part
thereof become immediately due and payable pursuant to Section 8.1 then, all LC
Obligations shall become immediately due and payable without regard to whether
or not actual drawings or payments on the Letters of Credit have occurred, and
Borrower shall be obligated to pay to LC Issuer immediately an amount equal to
the aggregate LC Obligations which are then outstanding. All amounts so paid
shall first be applied to Matured LC Obligations and then held by LC Issuer as
LC Collateral until such LC Obligations become Matured LC Obligations, at which
time such LC Collateral shall be applied to such Matured LC Obligations.

         (c) Investment of LC Collateral. Pending application thereof, all LC
Collateral shall be invested by LC Issuer in such investments as LC Issuer may
choose in its sole discretion. All interest on such investments shall be
reinvested or applied to Matured LC Obligations. When all Obligations have been
satisfied in full, including all LC Obligations, all Letters of Credit have
expired or been terminated, and all of Borrower's reimbursement obligations in
connection therewith have been satisfied in full, LC Issuer shall release any
remaining LC Collateral. Borrower hereby assigns and grants to LC Issuer a
continuing security interest in all LC Collateral paid by it to LC Issuer, all
investments purchased with such LC Collateral, and all proceeds thereof to
secure its Matured LC Obligations and its Obligations under this Agreement, the
Note, and the other Loan Documents, and Borrower agrees that such LC Collateral
and investments shall be subject to all of the terms and conditions of the
Security Documents. Borrower further agrees that LC Issuer shall have all of
the rights and remedies of a secured party under the Uniform Commercial Code as
adopted in the State of New York with respect to such security interest and
that an Event of Default under this Agreement shall constitute a default for
purposes of such security interest.

         (d) Payment of LC Collateral. When Borrower is required to provide LC
Collateral for any reason and fails to do so on the day when required, LC
Issuer may without notice to Borrower or any other Restricted Person provide
such LC Collateral (whether by application of proceeds of other Collateral, by
transfers from other accounts maintained with LC Issuer, or otherwise) using
any available funds of Borrower or any other Person also liable to make such
payments. Any such amounts which are required to be provided as LC Collateral
and which are not provided on the date required shall, for purposes of each
Security Document, be considered past due Obligations owing hereunder, and LC
Issuer is hereby authorized to exercise its respective rights under each
Security Document to obtain such amounts.

         Section 2.16. Hedging Agreement Indemnity. From time to time ING
Capital may provide an indemnity or other credit support on behalf of
Restricted Persons to AIG Trading Corporation, whereby ING Capital agrees to
pay the obligations of such Restricted Person arising from time to time under a
Hedging Agreement (a "Hedging Agreement Indemnity"). In consideration thereof,
Borrower hereby promises and agrees to pay to ING Capital each amount which ING
Capital is called upon to pay on behalf of or for the benefit of such



                                       29

<PAGE>   35



Restricted Person under a Hedging Agreement Indemnity. Borrower shall pay each
such amount, immediately upon demand, in legal tender of the United States in
same day funds. Such promise and agreement of Borrower is irrevocable and
unconditional. ING Capital is authorized and instructed to pay all demands for
payment under any such Hedging Agreement Indemnity after exercising reasonable
care to determine whether such demand or the amount thereof is correct.
Borrower hereby promises to pay to ING Capital, on demand, interest at the
Default Rate on any amount payable by Borrower under this section from the date
such amounts become due until they are paid. Borrower may enter into a separate
Reimbursement Agreement governing such promise and agreement of Borrower to pay
to ING Capital each amount which ING Capital is called upon to pay on behalf of
or for the benefit of such Restricted Person under a Hedging Agreement
Indemnity. Notwithstanding the existence of any such separate Reimbursement
Agreement, the obligation of Borrower described in this section shall be an
"Obligation" arising under this Agreement and shall be secured by and entitled
to the benefit of all Security Documents, whether or not the Security Documents
specifically describe such separate Reimbursement Agreement or the obligations
of Borrower under this section. Each payment under a Hedging Agreement
Indemnity (whether in response to a demand for payment or otherwise) shall
constitute a loan by ING Capital and shall be secured by and entitled to all
benefits under the Security Documents.

                       ARTICLE III - Payments to Lenders

         Section 3.1. General Procedures. Borrower will make each payment which
it owes under the Loan Documents to Agent for the account of the Bank Party to
whom such payment is owed. Each such payment must be received by Agent not
later than 11:00 a.m., New York, New York time, on the date such payment
becomes due and payable, in lawful money of the United States of America,
without set-off, deduction or counterclaim, and in immediately available funds.
Any payment received by Agent after such time will be deemed to have been made
on the next following Business Day. Should any such payment become due and
payable on a day other than a Business Day, the maturity of such payment shall
be extended to the next succeeding Business Day, and, in the case of a payment
of principal or past due interest, interest shall accrue and be payable thereon
for the period of such extension as provided in the Loan Document under which
such payment is due. Each payment under a Loan Document shall be due and
payable at the place provided therein and, if no specific place of payment is
provided, shall be due and payable at the place of payment of Agent's Note.
When Agent collects or receives money on account of the Obligations, Agent
shall distribute all money so collected or received, and each Bank Party shall
apply all such money so distributed, as follows:

                  (a) first, for the payment of all Obligations of any kind
         which are then due (and if such money is insufficient to pay all such
         Obligations, first to any reimbursements due Agent under Section 6.9
         or 10.4 and then to the partial payment of all other Obligations then
         due in proportion to the amounts thereof, or as Bank Parties shall
         otherwise agree);



                                       30

<PAGE>   36




                  (b) then for the prepayment of amounts owing under the Loan
         Documents (other than principal on the Notes) if so specified by
         Borrower;

                  (c) then for the prepayment of principal on the Notes (either
         the Term Notes, the Revolver Notes, or all, as specified by Borrower),
         together with accrued and unpaid interest on the principal so prepaid;
         and

                  (d) last, for the payment or prepayment of any other
         Obligations.

All payments applied to principal or interest on any Note shall be applied
first to any interest then due and payable, then to principal then due and
payable, and last to any prepayment of principal and interest in compliance
with Sections 2.6 and 2.7. All distributions of amounts described in any of
subsections (b), (c) or (d) above shall be made by Agent pro rata to each Bank
Party then owed Obligations described in such subsection in proportion to all
amounts owed to all Bank Parties which are described in such subsection;
provided that if any Lender then owes payments to LC Issuer for the purchase of
a participation under Section 2.12(c) hereof, any amounts otherwise
distributable under this section to such Lender shall be deemed to belong to LC
Issuer, to the extent of such unpaid payments, and Agent shall apply such
amounts to make such unpaid payments rather than distribute such amounts to
such Lender.

         Section 3.2. Capital Reimbursement. If either (a) the introduction or
implementation of or the compliance with or any change in or in the
interpretation of any Law, or (b) the introduction or implementation of or the
compliance with any request, directive or guideline from any central bank or
other governmental authority (whether or not having the force of Law) affects
or would affect the amount of capital required or expected to be maintained by
any Bank Party or any corporation controlling any Bank Party, then, upon demand
by such Bank Party, Borrower will pay to Agent for the benefit of such Bank
Party, from time to time as specified by such Bank Party, such additional
amount or amounts which such Bank Party shall determine to be appropriate to
compensate such Bank Party or any corporation controlling such Bank Party in
light of such circumstances, to the extent that such Bank Party reasonably
determines that the amount of any such capital would be increased or the rate
of return on any such capital would be reduced by or in whole or in part based
on the existence of the face amount of such Bank Party's Loans, Letters of
Credit, participations in Letters of Credit or commitments under this
Agreement.

         Section 3.3. Increased Cost of Eurodollar Loans or Letters of Credit.
If after the date hereof any applicable Law (whether now in effect or
hereinafter enacted or promulgated, including Regulation D) or any
interpretation or administration thereof by any governmental authority charged
with the interpretation or administration thereof (whether or not having the
force of Law):

                  (a) shall change the basis of taxation of payments to any
         Bank Party of any principal, interest, or other amounts attributable
         to any Eurodollar Loan or Letter of Credit or otherwise due under this
         Agreement in respect of any Eurodollar Loan or Letter of Credit (other
         than taxes imposed on the overall net income of such Bank Party 


                                       31

<PAGE>   37



         or any lending office of such Bank Party by any jurisdiction in which
         such Bank Party or any such lending office is located); or

                  (b) shall change, impose, modify, apply or deem applicable
         any reserve, special deposit or similar requirements in respect of any
         Eurodollar Loan or any Letter of Credit (excluding those for which
         such Bank Party is fully compensated pursuant to adjustments made in
         the definition of Eurodollar Rate) or against assets of, deposits with
         or for the account of, or credit extended by, such Bank Party; or

                  (c) shall impose on any Bank Party or the interbank
         eurocurrency deposit market any other condition affecting any
         Eurodollar Loan or Letter of Credit, the result of which is to
         increase the cost to any Bank Party of funding or maintaining any
         Eurodollar Loan or of issuing any Letter of Credit or to reduce the
         amount of any sum receivable by any Bank Party in respect of any
         Eurodollar Loan or Letter of Credit by an amount deemed by such Bank
         Party to be material,

then such Bank Party shall promptly notify Agent and Borrower in writing of the
happening of such event and of the amount required to compensate such Bank
Party for such event (on an after-tax basis, taking into account any taxes on
such compensation), whereupon (i) Borrower shall pay such amount to Agent for
the account of such Bank Party and (ii) Borrower may elect, by giving to Agent
and such Bank Party not less than three Business Days' notice, to convert all
(but not less than all) of any such Eurodollar Loans into Base Rate Loans.
Notwithstanding anything herein to the contrary, Borrower shall not be required
to reimburse any such Bank Party for any such increased costs incurred more
than 90 days prior to such Bank Party's notice thereof.

         Section 3.4. Availability. If (a) any change in applicable Laws, or in
the interpretation or administration thereof of or in any jurisdiction
whatsoever, domestic or foreign, shall make it unlawful or impracticable for
any Bank Party to fund or maintain Eurodollar Loans or to issue or participate
in Letters of Credit, or shall materially restrict the authority of any Bank
Party to purchase or take offshore deposits of dollars (i.e., "eurodollars"),
or (b) any Bank Party determines that matching deposits appropriate to fund or
maintain any Eurodollar Loan are not available to it, or (c) any Bank Party
determines that the formula for calculating the Eurodollar Rate does not fairly
reflect the cost to such Bank Party of making or maintaining loans based on
such rate, then, upon notice by such Bank Party to Borrower and Agent,
Borrower's right to elect Eurodollar Loans from such Bank Party (or, if
applicable, to obtain Letters of Credit) shall be suspended to the extent and
for the duration of such illegality, impracticability or restriction and all
Eurodollar Loans of such Bank Party which are then outstanding or are then the
subject of any Borrowing Notice and which cannot lawfully or practicably be
maintained or funded shall immediately become or remain, or shall be funded as,
Base Rate Loans of such Bank Party. Borrower agrees to indemnify each Bank
Party and hold it harmless against all costs, expenses, claims, penalties,
liabilities and damages which may result from any such change in Law,
interpretation or administration. Such indemnification shall be on an after-tax
basis, taking into account any taxes imposed on the amounts paid as indemnity.



                                       32

<PAGE>   38

         Section 3.5. Funding Losses. In addition to its other obligations
hereunder, Borrower will indemnify each Bank Party against, and reimburse each
Bank Party on demand for, any loss or expense incurred or sustained by such
Bank Party (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by a Bank Party to fund or
maintain Eurodollar Loans), as a result of (a) any payment or prepayment
(whether authorized or required hereunder or otherwise) of all or a portion of
a Eurodollar Loan on a day other than the day on which the applicable Interest
Period ends, (b) any payment or prepayment, whether required hereunder or
otherwise, of a Loan made after the delivery, but before the effective date, of
a Continuation/Conversion Notice, if such payment or prepayment prevents such
Continuation/Conversion Notice from becoming fully effective, (c) the failure
of any Loan to be made or of any Continuation/Conversion Notice to become
effective due to any condition precedent not being satisfied or due to any
other action or inaction of any Restricted Person, or (d) any conversion
(whether authorized or required hereunder or otherwise) of all or any portion
of any Eurodollar Loan into a Base Rate Loan or into a different Eurodollar
Loan on a day other than the day on which the applicable Interest Period ends.
Such indemnification shall be on an after-tax basis, taking into account any
taxes imposed on the amounts paid as indemnity.

         Section 3.6.  Reimbursable Taxes.  Borrower covenants and agrees that:

                  (a) Borrower will indemnify each Bank Party against and
         reimburse each Bank Party for all present and future income, stamp and
         other taxes, levies, costs and charges whatsoever imposed, assessed,
         levied or collected on or in respect of this Agreement or any
         Eurodollar Loans or Letters of Credit (whether or not legally or
         correctly imposed, assessed, levied or collected), excluding, however,
         any taxes imposed on or measured by the overall net income of Agent or
         such Bank Party or any lending office of such Bank Party by any
         jurisdiction in which such Bank Party or any such lending office is
         located (all such non-excluded taxes, levies, costs and charges being
         collectively called "Reimbursable Taxes" in this section). Such
         indemnification shall be on an after-tax basis, taking into account
         any taxes imposed on the amounts paid as indemnity.

                  (b) All payments on account of the principal of, and interest
         on, each Bank Party's Loans and Note, and all other amounts payable by
         Borrower to any Bank Party hereunder, shall be made in full without
         set-off or counterclaim and shall be made free and clear of and
         without deductions or withholdings of any nature by reason of any
         Reimbursable Taxes, all of which will be for the account of Borrower.
         In the event of Borrower being compelled by Law to make any such
         deduction or withholding from any payment to any Bank Party, Borrower
         shall pay on the due date of such payment, by way of additional
         interest, such additional amounts as are needed to cause the amount
         receivable by such Bank Party after such deduction or withholding to
         equal the amount which would have been receivable in the absence of
         such deduction or withholding. If Borrower should make any deduction
         or withholding as aforesaid, Borrower shall within 60 days thereafter
         forward to such Bank Party an official receipt or other official
         document evidencing payment of such deduction or withholding.



                                       33

<PAGE>   39




                  (c) If Borrower is ever required to pay any Reimbursable Tax
         with respect to any Eurodollar Loan, Borrower may elect, by giving to
         Agent and such Bank Party not less than three Business Days' notice,
         to convert all (but not less than all) of any such Eurodollar Loan
         into a Base Rate Loan, but such election shall not diminish Borrower's
         obligation to pay all Reimbursable Taxes.

                  (d) Notwithstanding the foregoing provisions of this section,
         Borrower shall be entitled, to the extent it is required to do so by
         Law, to deduct or withhold (and not to make any indemnification or
         reimbursement for) income or other similar taxes imposed by the United
         States of America (other than any portion thereof attributable to a
         change in federal income tax Laws effected after the date hereof) from
         interest, fees or other amounts payable hereunder for the account of
         any Bank Party, other than a Bank Party (i) who is a U.S. person for
         Federal income tax purposes or (ii) who has the Prescribed Forms on
         file with Agent (with copies provided to Borrower) for the applicable
         year to the extent deduction or withholding of such taxes is not
         required as a result of the filing of such Prescribed Forms, provided
         that if Borrower shall so deduct or withhold any such taxes, it shall
         provide a statement to Agent and such Bank Party, setting forth the
         amount of such taxes so deducted or withheld, the applicable rate and
         any other information or documentation which such Bank Party may
         reasonably request for assisting such Bank Party to obtain any
         allowable credits or deductions for the taxes so deducted or withheld
         in the jurisdiction or jurisdictions in which such Bank Party is
         subject to tax. As used in this section, "Prescribed Forms" means such
         duly executed forms or statements, and in such number of copies, which
         may, from time to time, be prescribed by Law and which, pursuant to
         applicable provisions of (x) an income tax treaty between the United
         States and the country of residence of the Bank Party providing the
         forms or statements, (y) the Internal Revenue Code of 1986, as amended
         from time to time, or (z) any applicable rules or regulations
         thereunder, permit Borrower to make payments hereunder for the account
         of such Bank Party free of such deduction or withholding of income or
         similar taxes.

         Section 3.7. Change of Applicable Lending Office. Each Bank Party
agrees that, upon the occurrence of any event giving rise to the operation of
Sections 3.2 through 3.6 with respect to such Bank Party, it will, if requested
by Borrower, use reasonable efforts (subject to overall policy considerations
of such Bank Party) to designate another Lending Office, provided that such
designation is made on such terms that such Bank Party and its Lending Office
suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise to the operation of any such
section. Nothing in this section shall affect or postpone any of the
obligations of Borrower or the rights of any Bank Party provided in Sections
3.2 through 3.6.

         Section 3.8. Replacement of Lenders. If any Bank Party seeks
reimbursement for increased costs under Sections 3.2 through 3.6, then within
ninety days thereafter -- provided no Event of Default then exists -- Borrower
shall have the right (unless such Bank Party withdraws its request for
additional compensation) to replace such Bank Party by requiring such Bank
Party to assign its Loans and Notes and its commitments hereunder to an
Eligible 


                                       34

<PAGE>   40



Transferee reasonably acceptable to Agent and to Borrower, provided
that: (i) all Obligations of Borrower owing to such Bank Party being replaced
(including such increased costs, but excluding principal and accrued interest
on the Notes being assigned) shall be paid in full to such Bank Party
concurrently with such assignment, and (ii) the replacement Eligible Transferee
shall purchase the Note being assigned by paying to such Bank Party a price
equal to the principal amount thereof plus accrued and unpaid interest thereon.
In connection with any such assignment Borrower, Agent, such Bank Party and the
replacement Eligible Transferee shall otherwise comply with Section 10.5.
Notwithstanding the foregoing rights of Borrower under this section, however,
Borrower may not replace any Bank Party which seeks reimbursement for increased
costs under Section 3.2 through 3.6 unless Borrower is at the same time
replacing all Bank Parties which are then seeking such compensation.

                  ARTICLE IV - Conditions Precedent to Lending

         Section 4.1. Documents to be Delivered. No Lender has any obligation
to make its first Loan, and LC Issuer has no obligation to issue the first
Letter of Credit unless Agent shall have received all of the following, at
Agent's office in New York, New York, duly executed and delivered and in form,
substance and date satisfactory to Agent:

                  (a) This Agreement and any other documents that Lenders are
         to execute in connection herewith.

                  (b)  Each Note.

                  (c) Each Security Document listed in the Security Schedule
         (other than those specified "to be delivered post-merger").

                  (d) Certain certificates of Borrower including:

                           (i) An "Omnibus Certificate" of the Vice President -
                  Controller and the Secretary or Assistant Secretary of
                  Borrower, which shall contain the names and signatures of the

                  (e) The making of such Loan or the issuance of such Letter of
         Credit shall not be prohibited by any Law and shall not subject any

                   ARTICLE V - Representations and Warranties

         To confirm each Bank Party's understanding concerning Borrower's and
its Subsidiaries' businesses, properties and obligations and to induce each
Bank Party to enter into this Agreement and to extend credit hereunder,
Borrower represents and warrants to each Bank Party that:

         Section 5.1.  No Default.  No Restricted Person is in default in the 
performance of any of the covenants and agreements contained in any Loan
Document. No event has occurred and is continuing which constitutes a Default.

         Section 5.2. Organization and Good Standing. Borrower and each of its
Subsidiaries is duly organized, validly existing and in good standing under the
Laws of its jurisdiction of organization, having all powers required to carry
on its business and enter into and carry out the transactions contemplated
hereby. Each Restricted Person is duly qualified, in good 


                                       38

<PAGE>   44



standing, and authorized to do business in all other jurisdictions within the
United States wherein the character of the properties owned or held by it or
the nature of the business transacted by it makes such qualification necessary.
Each Restricted Person has taken all actions and procedures customarily taken
in order to enter, for the purpose of conducting business or owning property,
each jurisdiction outside the United States wherein the character of the
properties owned or held by it or the nature of the business transacted by it
makes such actions and procedures desirable.

         Section 5.3. Authorization. Each Restricted Person has duly taken all
action necessary to authorize the execution and delivery by it of the Loan
Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder. Borrower is duly authorized to borrow funds hereunder.

         Section 5.4. No Conflicts or Consents. The execution and delivery by
the various Restricted Persons of the Loan Documents to which each is a party,
the performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (i) conflict with any provision of (1) any Law, (2) the
organizational documents of any Restricted Person, or (3) any agreement,
judgment, license, order or permit applicable to or binding upon any Restricted
Person, (ii) result in the acceleration of any Indebtedness owed by any
Restricted Person, or (iii) result in or require the creation of any Lien upon
any assets or properties of any Restricted Person except as expressly
contemplated in the Loan Documents. Except as expressly contemplated in the
Loan Documents no consent, approval, authorization or order of, and no notice
to or filing with, any Tribunal or third party is required in connection with
the execution, delivery or performance by any Restricted Person of any Loan
Document or to consummate any transactions contemplated by the Loan Documents.

         Section 5.5. Enforceable Obligations.  This Agreement is, and the other
Loan Documents when duly executed and delivered will be, legal, valid and
binding obligations of each Restricted Person which is a party hereto or
thereto, enforceable in accordance with their terms except as such enforcement
may be limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.

         Section 5.6. Initial Financial Statements. Borrower has heretofore
delivered to each Bank Party true, correct and complete copies of the Initial
Financial Statements. The Initial Financial Statements fairly present
Borrower's Consolidated financial position at the respective dates thereof and
the Consolidated results of Borrower's operations and Borrower's Consolidated
cash flows for the respective periods thereof. Since the date of the annual
Initial Financial Statements no Material Adverse Change has occurred, except as
reflected in the quarterly Initial Financial Statements or in the Disclosure
Schedule. All Initial Financial Statements were prepared in accordance with
GAAP.

         Section 5.7. Other Obligations and Restrictions. Neither Borrower nor
any of its Subsidiaries has any outstanding Liabilities of any kind (including
contingent obligations, tax assessments, and unusual forward or long-term
commitments) which is, in the aggregate, 


                                       39

financial condition and not shown in the Initial Financial Statements or
disclosed in the Disclosure Schedule or a Disclosure Report. Except as shown in
the Initial Financial Statements or disclosed in the Disclosure Schedule or a
Disclosure Report, neither Borrower nor any of its Subsidiaries is subject to
or restricted by any franchise, contract, deed, charter restriction, or other
instrument or restriction which could cause a Material Adverse Change.

         Section 5.8. Full Disclosure. No certificate, statement or other
information delivered herewith or heretofore by Borrower or any of its
Subsidiaries to any Bank Party in connection with the negotiation of this
Agreement or in connection with any transaction contemplated hereby contains
any untrue statement of a material fact or omits to state any material fact
known to Borrower or any of its Subsidiaries (other than industry-wide risks
normally associated with the types of businesses conducted by Borrower and its
Subsidiaries) necessary to make the statements contained herein or therein not
misleading as of the date made or deemed made. There is no fact known to
Borrower or any of its Subsidiaries (other than industry-wide risks normally
associated with the types of businesses conducted by Borrower and its
Subsidiaries) that has not been disclosed to each Bank Party in writing which
could cause a Material Adverse Change. There are no statements or conclusions
in any Engineering Report which are based upon or include misleading
information or fail to take into account material information regarding the
matters reported therein, it being understood that each Engineering Report is
necessarily based upon professional opinions, estimates and projections and
that Borrower does not warrant that such opinions, estimates and projections
will ultimately prove to have been accurate. Borrower has heretofore delivered
to each Bank Party true, correct and complete copies of the Initial Engineering
Report.

         Section 5.9. Litigation. Except as disclosed in the Initial Financial
Statements or in the Disclosure Schedule: (i) there are no actions, suits or
legal, equitable, arbitrative or administrative proceedings pending, or to the
knowledge of Borrower or any of its Subsidiaries threatened, against Borrower
or any of its Subsidiaries before any Tribunal which could cause a Material
Adverse Change, and (ii) there are no outstanding judgments, injunctions, 
writs, rulings or orders by any such Tribunal against Borrower or any of its
Subsidiaries, or any of their stockholders, partners, directors or officers,
which could cause a Material Adverse Change.

         Section 5.10. Labor Disputes and Acts of God. Except as disclosed in
the Disclosure Schedule or a Disclosure Report, neither the business nor the
properties of Borrower or any of its Subsidiaries has been affected by any
fire, explosion, accident, strike, lockout or other labor dispute, drought,
storm, hail, earthquake, embargo, act of God or of the public enemy or other
casualty (whether or not covered by insurance), which could cause a Material
Adverse Change.

         Section 5.11. ERISA Plans and Liabilities. All currently existing
ERISA Plans are listed in the Disclosure Schedule or a Disclosure Report.
Except as disclosed in the Initial Financial Statements or in the Disclosure
Schedule or a Disclosure Report, no Termination Event has occurred with respect
to any ERISA Plan and all ERISA Affiliates are in compliance 


                                      40
<PAGE>   46
with ERISA in all material respects. No ERISA Affiliate is required to
contribute to, or has any other absolute or contingent liability in respect of,
any "multiemployer plan" as defined in Section 4001 of ERISA. Except as set
forth in the Disclosure Schedule or a Disclosure Report: (i) no "accumulated
funding deficiency" (as defined in Section 412(a) of the Internal Revenue Code
of 1986, as amended) exists with respect to any ERISA Plan, whether or not
waived by the Secretary of the Treasury or his delegate, and (ii) the current
value of each ERISA Plan's benefits does not exceed the current value of such
ERISA Plan's assets available for the payment of such benefits by more than
$500,000.

         Section 5.12. Environmental and Other Laws. As used in this section:
"CERCLA" means the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, "CERCLIS" means the Comprehensive
Environmental Response, Compensation and Liability Information System List of
the Environmental Protection Agency, and "Release" has the meaning given such
term in 42 U.S.C. Section 9601(22). Except as set forth in the Disclosure
Schedule or a Disclosure Report:

         (a) Borrower and each of its Subsidiaries are conducting their
businesses in material compliance with all applicable Laws, including
Environmental Laws, and have all permits, licenses and authorizations required

permits, licenses and authorizations, and are also in compliance with all other
limitations, restrictions, conditions, standards, prohibitions, requirements,
obligations, schedules and timetables contained in any applicable Environmental
Law or in any regulation, code, plan, order, decree, judgment, injunction,
notice or demand letter issued, entered, promulgated or approved thereunder,
except to the extent failure to comply in either such case could not cause a
Material Adverse Change.

         (b) No notice, notification, demand, request for information,
citation, summons or order has been issued, no complaint has been filed, no
penalty has been assessed, and no investigation or review is pending (or, to
the best knowledge of Borrower and its Subsidiaries, threatened) by any 
Tribunal  or any other Person with respect to (i) any alleged generation,
treatment, storage, recycling, transportation, disposal, or Release of any
Hazardous Materials, either by Borrower or any of its Subsidiaries or on any
property owned by Borrower or any of its Subsidiaries, (ii) any material
remedial action which might be needed to respond to any such alleged
generation, treatment, storage, recycling, transportation, disposal, or
Release, or (iii) any alleged failure by Borrower or any of its Subsidiaries to
have any permit, license or authorization required in connection with the
conduct of its business or with respect to any such generation, treatment,
storage, recycling, transportation, disposal, or Release.

Hazardous Materials.

Hazardous Materials, other than as a generator, on any properties now or
previously owned or leased by Borrower

<PAGE>   47

or any of its Subsidiaries to an extent that such handling has caused, or could
cause, a Material Adverse Change; and

         (i)      to the best knowledge of Borrower after due inquiry, no PCBs
                  are or have been present at any properties now or previously
                  owned or leased by Borrower or any of its Subsidiaries to an
                  extent that such PCBs have caused, or could cause, a material
                  liability to Borrower or any of its Subsidiaries;

         (ii)     to the best knowledge of Borrower after due inquiry, no
                  asbestos is or has been present at any properties now or
                  previously owned or leased by Borrower or any of its
                  Subsidiaries to an extent that such asbestos has caused, or
                  could cause, a material liability to Borrower or any of its
                  Subsidiaries;

         (iii)    to the best knowledge of Borrower after due inquiry, there
                  are no underground storage tanks for Hazardous Materials,
                  active or abandoned, at any properties now or previously
                  owned or leased by Borrower or any of its Subsidiaries that
                  have caused, or could cause, a material liability to Borrower
                  or any of its Subsidiaries;

         (iv)     to the best knowledge of Borrower after due inquiry, no
                  Hazardous Materials have been Released, in a reportable
                  quantity, where such a quantity has been established by
                  statute, ordinance, rule, regulation or order, at, on or
                  under any properties now or previously owned or leased by
                  Borrower or any of its Subsidiaries to an extent that such

                  Borrower or any of its Subsidiaries to an extent that such
                  release has caused, or could cause, a Material Adverse
                  Change.

         In determining whether a representation or warranty contained in the
         foregoing clauses (i) through (v) is "false or incorrect in any
         material respect" on any date on or as of which made (including the
         date as of which such representation or warranty is initially made or
         may thereafter be restated) for purposes of Section 8.1(f) hereof,
         such representation and warranty shall be read solely for such purpose
         and no other, as if the qualification "to the best knowledge of
         Borrower after due inquiry" was deleted.

         (e) Neither Borrower nor any of its Subsidiaries has transported or
arranged for the transportation of any Hazardous Material to any location which

of federal, state or local enforcement actions or other investigations which
may lead to claims against Borrower or any of its Subsidiaries for clean-up
costs, remedial work, 


                                       42

no property now or previously owned or leased by Borrower or any of its

Laws on any of the real properties or properties owned or leased by Borrower or
any of its Subsidiaries, and no government actions have been taken (or, to the
best knowledge of Borrower and its Subsidiaries are in process) which could
subject any of such properties to such Liens; nor would Borrower or any of its

         contract or other instrument to which any of them is a party or by
         which any of them or any of their properties is bound, if such
         acceleration or default could cause a Material Adverse Change,

take all necessary or appropriate steps to remedy promptly any such Material
Adverse Change, Default, acceleration, default or Termination Event, to protect
against any such adverse claim, to defend any such suit or proceeding, and to

keep or cause to be kept insured by financially sound and reputable insurers

any Liens or other rights in Collateral securing any Obligations.

         Section 6.17. Bank Accounts; Offset. To secure the repayment of the
Obligations Borrower hereby grants to each Bank Party a security interest, a

deliver such a guaranty prior to the making of any Loan hereunder. Borrower
will cause each of its Subsidiaries to deliver to Agent, simultaneously with
its delivery of such a guaranty, written evidence satisfactory to Agent and its
counsel that such Subsidiary has taken all corporate or partnership action 
necessary to duly approve and authorize its execution, delivery and performance
of such guaranty and any other documents which it is required to execute.

         Section 6.19. Assignment of Proceeds. Notwithstanding that, by the

assigning to Agent and Lenders all of the "Production Proceeds" and
"Transportation, Separation and Processing Proceeds" (as defined therein and
collectively referred to in this section as "Proceeds") accruing to the
Collateral covered thereby, so long as no Default has occurred Restricted
Persons may continue to receive all such Proceeds, subject, however, to the
Liens created under the Security Documents, which Liens are hereby affirmed and
ratified. Upon the occurrence of a Default, Agent and Lenders may exercise all
rights and remedies granted under the Security Documents, including the right
to obtain possession of all Proceeds then held by Restricted Persons or to
receive directly from the purchasers, shippers or other payors, as the case may
be, all other Proceeds. In no case shall any failure, whether purposed or
inadvertent, by Agent or Lenders to collect directly any such Proceeds
constitute in any way a waiver, 


                                       51

<PAGE>   57
remission or release of any of their rights under the Security Documents, nor
shall any release of any Proceeds by Agent or Lenders to Restricted Persons
constitute a waiver, remission, or release of any other Proceeds or of any
rights of Agent or Lenders to collect other Proceeds thereafter.

         (d) as to property which is Collateral, any Liens expressly permitted
to encumber such Collateral under any Security Document covering such

         Section 7.3.  Hedging Contracts.  No Restricted Person will be a party 
to or in any manner be liable on any Hedging Contract, except:

         (a) contracts entered into with the purpose and effect of fixing
prices on Natural Gas or Natural Gas liquids expected to be bought or sold by
Restricted Persons, provided that at all times: (1) no such contract fixes a
price for a term of more than twenty-four (24) months; (2) the aggregate
monthly production of Natural Gas liquids covered by all such Hedging Contracts
(determined, in the case of contracts that are not settled on a monthly basis,
by a monthly proration acceptable to Agent) for any single month does not in
the aggregate exceed eighty percent (80%) of the aggregate Projected Natural
Gas Liquid Production of Restricted Persons anticipated to be sold in the 
ordinary course of their businesses for such month, (3) the aggregate monthly
volumes of Natural Gas covered by all such Hedging Contracts (determined, in

proration acceptable to Agent) for any single month does not in the aggregate
exceed eighty percent (80%) of the aggregate Projected Natural Gas Purchases of
Restricted Persons anticipated to be purchased in the ordinary course of their
businesses for such month, (4) no such contract entered into after the date
hereof requires any Restricted Person to put up money, assets, or other
security, other than letters of credit (and such contracts, in the aggregate,
do not require Restricted Persons to put up letters of credit in an aggregate
amount in excess of $1,000,000), against the event of its nonperformance prior
to actual default by such Restricted Person in performing its obligations
thereunder; (5) each such contract is with a counterparty or has a guarantor of
the obligation of the counterparty who (unless such counterparty is a Bank
Party, AIG Trading Corporation or one of their respective Affiliates) at the
time the contract is made has long-term obligations rated AA or Aa2 or better,
respectively, by either Rating Agency, or is an Approved Counterparty, and (6)
Restricted Persons shall not enter into 



                                       53

<PAGE>   59
any such contracts for the purpose of speculative investment. As used in this
subsection, the term "Projected Natural Gas Liquid Production" means the
projected production of Natural Gas liquids (measured by volume unit or BTU
equivalent, not sales price) for the term of the contracts or a particular
month, as applicable, from the interests in the Plants owned by Restricted
Persons, as such production is projected in the most recent Engineering Reports
delivered pursuant to Section 6.2(c), after deducting projected production from
any interests sold or under contract for sale that had been included in such
reports and after adding projected production from any interests that had not
been reflected in such reports but that are reflected in a separate or
supplemental reports meeting the requirements of such Section 6.2(c) hereof and
otherwise are satisfactory to Agent, and the term "Projected Natural Gas
Purchases" means the projected purchases of Natural Gas (measured by volume
unit or BTU equivalent, not sales price) for the term of the contracts or a
particular month, as applicable, as such purchases are projected in the most
recent Engineering Reports delivered pursuant to Section 6.2(c), after
deducting projected purchases from any interests sold or under contract for
sale that had been included in such reports and after adding projected
purchases from any interests that had not been reflected in such reports but
that are reflected in a separate or supplemental reports meeting the
requirements of such Section 6.2(c) hereof and otherwise are satisfactory to
Agent.

         (b) contracts entered into by a Restricted Person with the purpose and
effect of fixing interest rates on a principal amount of indebtedness of such
Restricted Person that is accruing interest at a variable rate, provided that
(1) the aggregate notional amount of such contracts never exceeds seventy-five
percent (75%) of the anticipated outstanding principal balance of the
indebtedness to be hedged by such contracts or an average of such principal
balances calculated using a generally accepted method of matching interest swap
contracts to declining principal balances, (2) the floating rate index of each
such contract generally matches the index used to determine the floating rates
of interest on the corresponding indebtedness to be hedged by such contract,
and (3) each such contract is with a counterparty or has a guarantor of the
obligation of the counterparty who (unless such counterparty is a Bank Party or
one of its Affiliates) at the time the contract is made has long-term
obligations rated AA or Aa2 or better, respectively, by either Rating Agency.

         Section 7.4. Limitation on Mergers, Issuances of Securities. Except as
expressly provided in this subsection no Restricted Person will merge or
consolidate with or into any other business entity. Any Subsidiary of Borrower
that is a Guarantor may, however, be merged into or consolidated with (i)
another Guarantor, or (ii) Borrower, so long as Borrower is the surviving
business entity. Borrower will not issue any securities other than shares of
its common stock and any options or warrants giving the holders thereof only
the right to acquire such shares. No Subsidiary of Borrower will issue any
additional shares of its capital stock or other securities or any options,
warrants or other rights to acquire such additional shares or other securities
except to Borrower and only to the extent not otherwise forbidden under the
terms hereof. No Subsidiary of Borrower which is a partnership will allow any
diminution of Borrower's interest (direct or indirect) therein.

         (a) equipment which is worthless or obsolete or which is replaced by
equipment of equal suitability and value.

         (b) inventory which is sold in the ordinary course of business on
ordinary trade terms.

Neither Borrower nor any of Borrower's Subsidiaries will sell, transfer or
otherwise dispose of capital stock of any of Borrower's Subsidiaries except
that any Subsidiary of Borrower may sell or issue its own capital stock to the
extent not otherwise prohibited hereunder. No Restricted Person will discount,
sell, pledge or assign any notes payable to it, accounts receivable or future
income except to the extent expressly permitted under the Loan Documents.

         Section 7.6. Limitation on Dividends and Redemptions. No Restricted
Person will declare or pay any dividends on, or make any other distribution in
respect of, any class of its capital stock or any partnership or other interest
in it, nor will any Restricted Person directly or indirectly make any capital
contribution to or purchase, redeem, acquire or retire any shares of the
capital stock of or partnership interests in any Person (whether such interests
are now or hereafter issued, outstanding or created), or cause or permit any
reduction or retirement of the capital stock of any Restricted Person, except
as expressly provided in this section. Such dividends, distributions,
contributions, purchases, redemptions, acquisitions, retirements or reductions
may be made by Borrower and the Guarantors (i) without limitation to Borrower;
(ii) to Guarantors which are Subsidiaries of Borrower, to the extent permitted
under the investment restrictions of Section 7.7; (iii) during Fiscal Year 1997
only, to pay the owners of Borrower's preferred stock a 7% dividend, provided,
the aggregate amount of such preferred stock dividend shall not exceed $140,000
in any Fiscal Quarter; (iv) after the one-year anniversary hereof and so long
as no Default has occurred and is continuing, to other Persons, to the extent 
that the aggregate value of all such dividends, distributions, contributions,
purchases, redemptions, acquisitions, retirements and reductions made in any
Fiscal Year does not exceed ten percent (10%) of Borrower's Consolidated Net
Income for the period commencing with such one-year anniversary (including any
dividends under any preferred stock issued by Borrower).

         Section 7.7. Limitation on Investments and New Businesses; Limitation

owned or hereafter formed or acquired with the consent of Majority Lenders)
that are Guarantors, or (iv) make any significant acquisitions or investments
in any properties other than gas gathering and transportation pipelines and gas


                                       55

operated in a normal and prudent manner, (ii) loans to Borrower or to any
Guarantor, and (iii) loans to employees of any Restricted Person, so long as

         Section 7.9. Transactions with Affiliates. Neither Borrower nor any of
its Subsidiaries will engage in any material transaction with any of its
Affiliates on terms which are less favorable to it than those which would have
been obtainable at the time in arm's-length dealing with Persons other than
such Affiliates, provided that such restriction shall not apply to transactions
among Restricted Persons.

         Section 7.10. Certain Contracts; Amendments; Multiemployer ERISA

ability of any Subsidiary of Borrower to: (i) pay dividends or make other
distributions to Borrower, (ii) to redeem equity interests held in it by
Borrower, (iii) to repay loans and other indebtedness owing by it to Borrower,
or (iv) to transfer any of its assets to Borrower. No Restricted Person will
enter into any "take-or-pay" contract or other contract or arrangement for the
purchase of goods or services which obligates it to pay for such goods or
service regardless of whether they are delivered or furnished to it. No
Restricted Person will amend or permit any amendment to any contract or lease
which releases, qualifies, limits, makes contingent or otherwise detrimentally
affects the rights and benefits of Agent or any Lender under or acquired 
pursuant to any Security Documents. No ERISA Affiliate will incur any
obligation to contribute to any "multiemployer plan" as defined in Section 4001
of ERISA.

issued hereunder to secure payables) shall be included as current liabilities,

Borrower's Consolidated current liabilities will be calculated without
including any payments of principal on the Term Notes which are required to be
repaid within one year from the time of calculation.

Income (if positive) for each Fiscal Quarter from and after September 30, 1997
to and including the date of determination thereof, computed on a cumulative
basis for such period plus (iii) seventy-five percent (75%) of the net proceeds

Loan Document at any time ceases to be valid, binding and enforceable as
warranted in Section 5.5 for any reason other than its release or subordination
by Agent;

         (g) Borrower or any of its Subsidiaries fails to duly observe, perform

<PAGE>   65
thereupon be immediately due and payable, without demand, presentment, notice
of demand or of dishonor and nonpayment, protest, notice of protest, notice of
intention to accelerate, declaration or notice of acceleration, or any other
notice or declaration of any kind, all of which are hereby expressly waived by
Borrower and each Restricted Person who at any time ratifies or approves this

each Bank Party may protect and enforce its rights under the Loan Documents by
any appropriate proceedings, including proceedings for specific performance of
any covenant or agreement contained in any Loan Document, and each Bank Party
may enforce the payment of any Obligations due it or enforce any other legal or
equitable right which it may have. All rights, remedies and powers conferred
upon Bank Parties under the Loan Documents shall be deemed cumulative and not
exclusive of any other rights, remedies or powers available under the Loan
Documents or at Law or in equity.

                               ARTICLE IX - Agent

         Section 9.1. Appointment and Authority. Each Bank Party hereby
irrevocably authorizes Agent, and Agent hereby undertakes, to receive payments
of principal, interest and other amounts due hereunder as specified herein and
to take all other actions and to exercise such powers under the Loan Documents
as are specifically delegated to Agent by the terms hereof or thereof, together
with all other powers reasonably incidental thereto. The relationship of Agent
to the other Bank Parties is only that of one commercial lender acting as
administrative agent for others, and nothing in the Loan Documents shall be
construed to constitute Agent a trustee or other fiduciary for any holder of
any of the Notes or of any participation therein nor to impose on Agent duties
and obligations other than those expressly provided for in the Loan Documents.
With respect to any matters not expressly provided for in the Loan Documents
and any matters which the Loan Documents place within the discretion
of Agent, Agent shall not be required to exercise any discretion or take any
action, and it may request instructions from Lenders with respect to any such
matter, in which case it shall be required to act or to refrain from acting
(and shall be fully protected and free from liability to all Lenders in so
acting or refraining from acting) upon the instructions of Majority Lenders
(including itself), provided, however, that Agent shall not be required to take
any action which exposes it to a risk of personal liability that it considers
unreasonable or which is contrary to the Loan Documents or to applicable Law.

         Section 9.2. Exculpation, Agent's Reliance, Etc. Neither Agent nor any
of its directors, officers, agents, attorneys, or employees shall be liable for
any action taken or omitted to be taken by any of them under or in connection
with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that
each shall be liable for its own gross negligence or willful misconduct.
Without limiting the generality of the foregoing, Agent (a) may treat the payee
of any Note as the holder thereof until Agent receives written notice of the
assignment or transfer thereof in accordance with this Agreement, signed by
such payee and in form satisfactory to Agent; (b) may consult with legal
counsel (including counsel for Borrower), independent public accountants and
other experts selected by it and shall not be 


                                       60

<PAGE>   66
liable for any action taken or omitted to be taken by it in accordance with the
advice of such counsel, accountants or experts; (c) makes no warranty or
representation to any other Bank Party and shall not be responsible to any
other Bank Party for any statements, warranties or representations made in or
in connection with the Loan Documents; (d) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms,
covenants or conditions of the Loan Documents on the part of any Restricted
Person or to inspect the property (including the books and records) of Borrower
or any of its Subsidiaries; (e) shall not be responsible to any other Bank
Party for the due execution, legality, validity, enforceability, genuineness,
sufficiency or value of any Loan Document or any instrument or document
furnished in connection therewith; (f) may rely upon the representations and
warranties of each Restricted Person and the Lenders in exercising its powers
hereunder; (g) shall incur no liability under or in respect of the Loan
Documents by acting upon any notice, consent, certificate or other instrument
or writing (including any telecopy, telegram, cable or telex) believed by it to
be genuine and signed or sent by the proper Person or Persons; and (h) shall
not be obligated to initiate or conduct any litigation or collection
proceedings.

         Section 9.3. Credit Decisions; Limited Scope of Agent's Duties. Each
Bank Party acknowledges that it has, independently and without reliance upon
any other Bank Party, made its own analysis of Borrower and the transactions
contemplated hereby and its own independent decision to enter into this
Agreement and the other Loan Documents. Each Bank Party also acknowledges that
it will, independently and without reliance upon any other Bank Party and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
the Loan Documents. Except for notices, reports and other documents and
information expressly required to be furnished to another Bank Party by Agent
hereunder, Agent shall have no duty or responsibility to provide any other Bank
Party with any credit or other information concerning the affairs, financial
condition or businesses of the Company or any of its Subsidiaries (or any of
their Affiliates) which may come into the possession of Agent or any of
its Affiliates. Agent shall not be required to keep itself informed as to the
performance or observance by Restricted Persons of this Agreement or any other
Loan Document or other document referred to or provided for herein or to
inspect the properties or books of Borrower or any of its Subsidiaries, and
shall not be deemed to have knowledge or notice of the occurrence of a Default
(other than the non-payment of any obligation to the extent the same is
required to be paid to Agent for the account of LC Issuer or Lenders) unless it
has received notice from another Bank Party or Borrower specifying such Default
and stating that such notice is a "Notice of Default". In the event Agent
receives such a notice of the occurrence of a Default (or upon the occurrence
of any such non-payment), Agent shall give prompt notice thereof to each Bank
Party and shall take such action with respect to such Default as shall be
directed by Majority Lenders, provided that Agent may, but shall not be
obligated to, take such action, or refrain from taking such action, with
respect to such Default as Agent may deem advisable in the best interest of
Bank Parties.

         Section 9.4. Indemnification. Each Lender agrees to indemnify Agent
(to the extent not reimbursed by Borrower within ten (10) days after demand)
from and against such Lender's Percentage Share of any and all liabilities,
obligations, claims, losses, damages, 


                                       61

<PAGE>   67
penalties, fines, actions, judgments, suits, settlements, costs, expenses or
disbursements (including reasonable fees of attorneys, accountants, experts and
advisors) of any kind or nature whatsoever (in this section collectively called
"liabilities and costs") which to any extent (in whole or in part) may be
imposed on, incurred by, or asserted against Agent growing out of, resulting
from or in any other way associated with any of the Collateral, the Loan
Documents and the transactions and events at any time associated therewith or
contemplated therein (including any enforcement of the Loan Documents, any
violation or noncompliance with any Environmental Laws by any Person, or any
liabilities or duties of any Person with respect to Hazardous Materials found
in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY
CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT,

provided only that no Lender shall be obligated under this section to indemnify
Agent for that portion, if any, of any liabilities and costs which is
proximately caused by Agent's own individual gross negligence or willful
misconduct. Cumulative of the foregoing, each Lender agrees to reimburse Agent
promptly upon demand for such Lender's Percentage Share of any costs and
expenses to be paid to Agent by Borrower under Section 10.4(a) to the extent
that Agent is not timely reimbursed for such expenses by Borrower as provided
in such section. As used in this section the term "Agent" shall refer not only
to the Person designated as such in Section 1.1 but also to each director,
officer, agent, attorney, employee, representative and Affiliate of such
Person.

         Section 9.5. Rights as Lender. In its capacity as a Lender, Agent
shall have the same rights and obligations as any Lender and may exercise such
rights as though it were not Agent. Agent may accept deposits from, lend money
to, act as Trustee under indentures of, and generally engage in any kind of
business with Borrower, any of its Subsidiaries, or any of their respective
Affiliates, all as if it were not Agent hereunder and without any duty to
account therefor to any other Lender.

         Section 9.6. Sharing of Set-Offs and Other Payments. Each Bank Party
agrees that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against Borrower
or otherwise, obtain payment of a portion of the aggregate Obligations owed to
it which, taking into account all distributions made by Agent under Section
3.1, causes such Bank Party to have received more than it would have received
had such payment been received by Agent and distributed pursuant to Section
3.1, then (a) it shall be deemed to have simultaneously purchased and shall be
obligated to purchase interests in the Obligations as necessary to cause all
Bank Parties to share all payments as provided for in Section 3.1, and (b) such
other adjustments shall be made from time to time as shall be equitable to
ensure that Agent and all Lenders share all payments of Obligations as provided
in Section 3.1; provided, however, that nothing herein contained shall in any
way affect the right 


                                       62

<PAGE>   68
of any Bank Party to obtain payment (whether by exercise of rights of banker's
lien, set-off or counterclaim or otherwise) of indebtedness other than the
Obligations. Borrower expressly consents to the foregoing arrangements and
agrees that any holder of any such interest or other participation in the
Obligations, whether or not acquired pursuant to the foregoing arrangements,
may to the fullest extent permitted by Law exercise any and all rights of
banker's lien, set-off, or counterclaim as fully as if such holder were a
holder of the Obligations in the amount of such interest or other
participation. If all or any part of any funds transferred pursuant to this
section is thereafter recovered from the seller under this section which
received the same, the purchase provided for in this section shall be deemed to
have been rescinded to the extent of such recovery, together with interest, if
any, if interest is required pursuant to Tribunal order to be paid on account
of the possession of such funds prior to such recovery.

         Section 9.7. Investments. Whenever Agent in good faith determines that
it is uncertain about how to distribute to Lenders any funds which it has
received, or whenever Agent in good faith determines that there is any dispute
among Lenders about how such funds should be distributed, Agent may choose to
defer distribution of the funds which are the subject of such uncertainty or
dispute. If Agent in good faith believes that the uncertainty or dispute will
not be promptly resolved, or if Agent is otherwise required to invest funds
pending distribution to Lenders, Agent shall invest such funds pending
distribution; all interest on any such investment shall be distributed upon the
distribution of such investment and in the same proportion and to the same
Persons as such investment.

         Section 9.8. Benefit of Article IX. The provisions of this Article
(other than the following Section 9.9) are intended solely for the benefit of
Bank Parties, and no Restricted Person shall be entitled to rely on any such
provision or assert any such provision in a claim or defense against any Bank 
Party. Bank Parties may waive or amend such provisions as they desire without
any notice to or consent of Borrower or any Restricted Person.

         Section 9.9. Resignation. Agent may resign at any time by giving
written notice thereof to Lenders and Borrower. Each such notice shall set
forth the date of such resignation. Upon any such resignation Majority Lenders
shall have the right to appoint a successor Agent. A successor must be
appointed for any retiring Agent, and such Agent's resignation shall become
effective when such successor accepts such appointment. If, within thirty days
after the date of the retiring Agent's resignation, no successor Agent has been
appointed and has accepted such appointment, then the retiring Agent may
appoint a successor Agent, which shall be a commercial bank organized or
licensed to conduct a banking or trust business under the Laws of the United
States of America or of any state thereof. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, the retiring Agent shall
be discharged from its duties and obligations under this Agreement and the
other Loan Documents. After any retiring Agent's resignation hereunder the
provisions of this Article IX shall continue to inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent under the Loan
Documents.

                           ARTICLE X - Miscellaneous

         Section 10.1.  Waivers and Amendments; Acknowledgments.

         (a) Waivers and Amendments. No failure or delay (whether by course of
conduct or otherwise) by any Bank Party in exercising any right, power or
remedy which such Bank Party may have under any of the Loan Documents shall
operate as a waiver thereof or of any other right, power or remedy, nor shall
any single or partial exercise by any Bank Party of any such right, power or
remedy preclude any other or further exercise thereof or of any other right,
power or remedy. No waiver of any provision of any Loan Document and no consent
to any departure therefrom shall ever be effective unless it is in writing and
signed as provided below in this section, and then such waiver or consent shall
be effective only in the specific instances and for the purposes for which
given and to the extent specified in such writing. No notice to or demand on
any Restricted Person shall in any case of itself entitle any Restricted Person
to any other or further notice or demand in similar or other circumstances.
This Agreement and the other Loan Documents set forth the entire understanding
between the parties hereto with respect to the transactions contemplated herein
and therein and supersede all prior discussions and understandings with respect
to the subject matter hereof and thereof, and no waiver, consent, release,
modification or amendment of or supplement to this Agreement or the other Loan
Documents shall be valid or effective against any party hereto unless the same
is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if
such party is Agent or LC Issuer, by such party, and (iii) if such party is a
Lender, by such Lender or by Agent on behalf of Lenders with the written
consent of Majority Lenders (which consent has already been given as to the
termination of the Loan Documents as provided in Section 10.9). Notwithstanding
the foregoing or anything to the contrary herein, Agent shall not, without the
prior consent of each individual Lender, execute and deliver on behalf of such
Lender any waiver or amendment which would: (1) waive any of the conditions
specified in Article IV (provided that Agent may in its discretion withdraw any 
request it has made under Section 4.3(e)), (2) increase the Revolving Credit
Maximum Loan Amount of any Revolving Credit Lender or subject any Lender to any
additional obligations, (3) reduce any fees payable to such Lender hereunder,
or the principal of, or interest on, such Lender's Note, (4) postpone any date
fixed for any payment of any such fees, principal or interest, (5) amend the
definition herein of "Eligible Accounts" or the "advance rate" related thereto
as set forth in Section 2.9 hereof, (6) amend the definition herein of
"Majority Lenders" or otherwise change the aggregate amount of Percentage
Shares which is required for Agent, Lenders or any of them to take any
particular action under the Loan Documents, or (7) release Borrower from its
obligation to pay such Lender's Note or any Guarantor from its guaranty of such
payment.

         (b) Acknowledgments and Admissions. Borrower hereby represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in
the negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement
and the other Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by Agent or any Lender,
whether written, oral or implicit, other than as expressly set out in this
Agreement or in another Loan Document delivered on or after the date hereof,
(iii) there are no 


                                       64

<PAGE>   70
representations, warranties, covenants, undertakings or agreements by any Bank
Party as to the Loan Documents except as expressly set out in this Agreement or
in another Loan Document delivered on or after the date hereof, (iv) no Bank
Party has any fiduciary obligation toward Borrower with respect to any Loan
Document or the transactions contemplated thereby, (v) the relationship
pursuant to the Loan Documents between Borrower and the other Restricted
Persons, on one hand, and each Bank Party, on the other hand, is and shall be
solely that of debtor and creditor, respectively, (vi) no partnership or joint
venture exists with respect to the Loan Documents between any Restricted Person
and any Bank Party, (vii) Agent is not Borrower's Agent, but Agent for Lenders,
(viii) should an Event of Default or Default occur or exist, each Bank Party
will determine in its sole discretion and for its own reasons what remedies and
actions it will or will not exercise or take at that time, (ix) without
limiting any of the foregoing, Borrower is not relying upon any representation
or covenant by any Bank Party, or any representative thereof, and no such
representation or covenant has been made, that any Bank Party will, at the time
of an Event of Default or Default, or at any other time, waive, negotiate,
discuss, or take or refrain from taking any action permitted under the Loan
Documents with respect to any such Event of Default or Default or any other
provision of the Loan Documents, and (x) all Bank Parties have relied upon the
truthfulness of the acknowledgments in this section in deciding to execute and
deliver this Agreement and to become obligated hereunder.

         (c) Representation by Lenders. Each Lender hereby represents that it
will acquire its Note for its own account in the ordinary course of its
commercial lending business; however, the disposition of such Lender's property
shall at all times be and remain within its control and, subject to Section
10.5, such Lender may sell or otherwise transfer its Note, any participation
interest or other interest in its Note, or any of its other rights and
obligations under the Loan Documents.

         (d) Joint Acknowledgment. THIS WRITTEN AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         Section 10.2. Survival of Agreements; Cumulative Nature. All of
Restricted Persons' various representations, warranties, covenants and
agreements in the Transaction Documents shall survive the execution and
delivery of this Agreement and the other Loan Documents and the performance
hereof and thereof, including the making or granting of the Loans and the
delivery of the Notes and the other Loan Documents, and shall further survive
until all of the Obligations are paid in full to each Bank Party and all of
Bank Parties' obligations to Restricted Persons are terminated. All statements
and agreements contained in any certificate or other instrument delivered by
Borrower or any of its Subsidiaries to any Bank Party under any Loan Document
shall be deemed representations and warranties by Borrower or 


                                       65

<PAGE>   71
agreements and covenants of Borrower under this Agreement. The representations,
warranties, indemnities, and covenants made by Restricted Persons in the Loan
Documents, and the rights, powers, and privileges granted to Bank Parties in
the Loan Documents, are cumulative, and, except for expressly specified waivers
and consents, no Loan Document shall be construed in the context of another to
diminish, nullify, or otherwise reduce the benefit to any Bank Party of any
such representation, warranty, indemnity, covenant, right, power or privilege.
In particular and without limitation, no exception set out in this Agreement to
any representation, warranty, indemnity, or covenant herein contained shall
apply to any similar representation, warranty, indemnity, or covenant contained
in any other Loan Document, and each such similar representation, warranty,
indemnity, or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various Loan Documents.

         Section 10.3. Notices. All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Agent may give telephonic notices to the other Bank Parties), and shall be
deemed sufficiently given or furnished if delivered by personal delivery, by
telecopy, by delivery service with proof of delivery, or by registered or
certified United States mail, postage prepaid, to Borrower and Restricted
Persons at the address of Borrower specified on the signature pages hereto and
to each Bank Party at its address specified on the signature pages hereto
(unless changed by similar notice in writing given by the particular Person
whose address is to be changed). Any such notice or communication shall be
deemed to have been given (a) in the case of personal delivery or delivery
service, as of the date of first attempted delivery during normal business
hours at the address provided herein, (b) in the case of telecopy, upon
receipt, or (c) in the case of registered or certified United States mail,
three days after deposit in the mail; provided, however, that no Borrowing 
Notice or Continuation/Conversion Notice shall become effective until actually
received by Agent.

         Section 10.4.  Payment of Expenses; Indemnity.

         (a) Payment of Expenses. Whether or not the transactions contemplated
by this Agreement are consummated, Borrower will promptly (and in any event,
within 30 days after any invoice or other statement or notice) pay: (i) all
transfer, stamp, mortgage (except as may be prohibited by Law), documentary or
other similar taxes, assessments or charges levied by any governmental or
revenue authority in respect of this Agreement or any of the other Loan
Documents or any other document referred to herein or therein, (ii) all
reasonable costs and expenses incurred by or on behalf of Agent (including fees
of attorneys, accountants, engineers and other experts and advisors, travel
costs and miscellaneous expenses) in connection with (1) the negotiation,
preparation, execution and delivery of the Loan Documents, and any and all
consents, waivers or other documents or instruments relating thereto, (2) the
filing, recording, refiling and re-recording of any Loan Documents and any
other documents or instruments or further assurances required to be filed or
recorded or refiled or re-recorded by the terms of any Loan Document, (3) the
borrowings hereunder and other action reasonably required in the course of
administration hereof, or (4) monitoring or confirming (or preparation or
negotiation 


                                       66

<PAGE>   72
of any document related to) Borrower's compliance with any covenants or
conditions contained in this Agreement or in any Loan Document, and (iii) all
reasonable costs and expenses incurred by or on behalf of any Bank Party
(including fees of attorneys, accountants, engineers and other experts and
advisors) in connection with the defense or, upon the occurrence of a Default,
enforcement of any of the Loan Documents or the defense of any Bank Party's
exercise of its rights thereunder. In addition to the foregoing, until and all
Obligations have been paid in full, Borrower will also pay or reimburse Agent
for all reasonable out-of-pocket costs and expenses of Agent or its agents or
employees in connection with the continuing administration of the Loans and the
related due diligence of Agent, including travel and miscellaneous expenses and
fees and expenses of Agent's outside counsel, reserve engineers and consultants
engaged in connection with the Loan Documents.

         (b) Indemnity. Borrower agrees to indemnify each Bank Party, upon
demand, from and against any and all liabilities, obligations, claims, losses,
damages, penalties, fines, actions, judgments, suits, settlements, costs,
expenses or disbursements (including reasonable fees of attorneys, accountants,
engineers and other experts and advisors) of any kind or nature whatsoever (in
this section collectively called "liabilities and costs") which to any extent
(in whole or in part) may be imposed on, incurred by, or asserted against such
Bank Party growing out of, resulting from or in any other way associated with
any of the Collateral, the Loan Documents and the transactions and events at
any time associated therewith or contemplated therein (including any
enforcement or defense of the Loan Documents, any violation or noncompliance
with any Environmental Laws by any Person, or any liabilities or duties of any
Person with respect to Hazardous Materials found in or released into the
environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY
CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY BANK PARTY,

provided only that no Bank Party shall be entitled under this section to
receive indemnification for that portion, if any, of any liabilities and costs
which is proximately caused by its own individual gross negligence or willful
misconduct. As used in this section the term "Bank Parties" shall refer not
only to the Persons designated as such in Section 1.1 but also to each
director, officer, agent, attorney, employee, representative and Affiliate of
such Persons.

         Section 10.5. Joint and Several Liability; Parties in Interest;
Assignments. All Obligations which are incurred by two or more Restricted
Persons shall be their joint and several obligations and liabilities. All
grants, covenants and agreements contained in the Loan Documents shall bind and
inure to the benefit of the parties thereto and their respective successors and
assigns; provided, however, that no Restricted Person may assign or transfer
any of its rights or delegate any of its duties or obligations under any Loan
Document without the prior consent of Majority Lenders. Neither Borrower nor
any Affiliates of Borrower shall 


                                       67

<PAGE>   73
directly or indirectly purchase or otherwise retire any Obligations owed to any
Lender nor will any Lender accept any offer to do so, unless each Lender shall
have received substantially the same offer with respect to the same Percentage
Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower
at any time purchases some but less than all of the Obligations owed to all
Bank Parties, such purchaser shall not be entitled to any rights of any Bank
Party under the Loan Documents unless and until Borrower or its Affiliates have
purchased all of the Obligations.

         (b) No Lender shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person other than an Eligible Transferee, and then only if the agreement
between such Lender and such participant at all times provides: (i) that such
participation exists only as a result of the agreement between such participant
and such Lender and that such transfer does not give such participant any right
to vote as a Lender or any other direct claims or rights against any Person
other than such Lender, (ii) that such participant is not entitled to payment
from any Restricted Person under Sections 3.2 through 3.6 of amounts in excess
of those payable to such Lender under such sections (determined without regard
to the sale of such participation), (iii) that (unless Agent and Borrower
otherwise consent) such participant has an identical percentage interest
(through such participation) in both the Term Loans and the Revolving Credit
Loans, and (iv) unless such participant is an Affiliate of such Lender, that
such participant shall not be entitled to require such Lender to take any
action under any Loan Document or to obtain the consent of such participant
prior to taking any action under any Loan Document, except for actions which
would require the consent of all Lenders under the last sentence of subsection
(a) of Section 10.1. No Lender selling such a participation shall, as between
the other parties hereto and such Lender, be relieved of any of its obligations
hereunder as a result of the sale of such participation. Each Lender which 
sells any such participation to any Person (other than an Affiliate of such 
Lender) shall give prompt notice thereof to Agent and Borrower.

         (c) Except for sales of participations under the immediately preceding
subsection (b), no Lender shall make any assignment or transfer of any kind of
its commitments or any of its rights under its Loans or under the Loan
Documents, except for assignments to an Eligible Transferee, and then only if
such assignment is made in accordance with the following requirements:

                  (i) Each such assignment shall apply to all Obligations owing
         to the assignor Lender hereunder and to the unused portion of the
         assignor Lender's commitments, so that after such assignment is made
         the assignor Lender shall have a fixed (and not a varying) Percentage
         Share in its Loans and Notes, have an identical Percentage Share in
         both the Term Loans and the Revolving Credit Loans (unless Agent and
         Borrower otherwise consent), and be committed to make that Percentage
         Share of all future Loans, the assignee shall have a fixed Percentage
         Share in such Loans and Notes, have an identical Percentage Share in
         both the Term Loans and the Revolving Credit Loans (unless Agent and
         Borrower otherwise consent), and be committed to make that Percentage
         Share of all future Loans, and the individual Percentage Share of the
         Revolving Credit 


                                       68

<PAGE>   74
         Maximum Loan Amount of each of the assignor and assignee shall equal
         or exceed $5,000,000 (unless such assignor Lender is assigning one
         hundred percent (100%) of its Percentage Share).

                  (ii) The parties to each such assignment shall execute and
         deliver to Agent, for its acceptance and recording in the "Register"
         (as defined below in this section), an Assignment and Assumption
         Agreement substantially in the form of Exhibit J, appropriately
         completed, together with the Note subject to such assignment and, as
         to any such assignment after the Syndication Date, and shall pay a
         processing fee to Agent of $2,500. Upon such execution, delivery, and
         payment and upon the satisfaction of the conditions set out in such
         Assignment and Assumption Agreement, then (i) Borrower shall issue new
         Notes to such assignor and assignee upon return of the old Notes to
         Borrower, and (ii) as of the "Settlement Date" specified in such
         Assignment and Assumption Agreement the assignee thereunder shall be a
         party hereto and a Lender hereunder and Agent shall thereupon deliver
         to Borrower and each Lender a schedule showing the revised Percentage
         Shares of such assignor Lender and such assignee Lender and the
         Percentage Shares of all other Lenders.

                  (iii) Each assignee Lender which is not a United States
         person (as such term is defined in Section 7701(a)(30) of the Internal
         Revenue Code of 1986, as amended) for Federal income tax purposes,
         shall (to the extent it has not already done so) provide Agent and
         Borrower with the "Prescribed Forms" referred to in Section 3.6(d).

         (d) Nothing contained in this section shall prevent or prohibit any
Lender from assigning or pledging all or any portion of its Loans and Note to
any Federal Reserve Bank as collateral security pursuant to Regulation A of the 
Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank; provided that no such assignment or pledge
shall relieve such Lender from its obligations hereunder.

         (e) By executing and delivering an Assignment and Assumption
Agreement, each assignee Lender thereunder will be confirming to and agreeing
with Borrower, Agents and each other Lender hereunder that such assignee
understands and agrees to the terms of the Loan Documents, including Article IX
hereof.

         (f) Agent shall maintain a copy of each Assignment and Assumption
Agreement and a register for the recordation of the names and addresses of
Lenders and the Percentage Shares of, and principal amount of the Loans owing
to, each Lender from time to time (in this section called the "Register"). The
entries in the Register shall be conclusive, in the absence of manifest error,
and Borrower and each Bank Party may treat each Person whose name is recorded
in the Register as a Lender hereunder for all purposes. The Register shall be
available for inspection by Borrower or any Bank Party at any reasonable time
and from time to time upon reasonable prior notice.

         Section 10.6. Confidentiality. Each Bank Party agrees that it will
take all reasonable steps to keep confidential any proprietary information
given to it by Borrower or any of its 


                                       69

<PAGE>   75
Subsidiaries, provided, however, that this restriction shall not apply to
information which (i) has at the time in question entered the public domain,
(ii) is required to be disclosed by Law (whether valid or invalid) of any
Tribunal, (iii) is disclosed to any Bank Party's Affiliates, auditors,
attorneys, or agents, (iv) is furnished to any other Bank Party or to any
purchaser or prospective purchaser of participations or other interests in any
Loan or Loan Document, provided each such purchaser or prospective purchaser
first agrees to hold such information in confidence on the terms provided in
this section), or (v) is disclosed in the course of enforcing its rights and
remedies during the existence of an Event of Default.

         Section 10.7. Governing Law; Submission to Process. EXCEPT TO THE
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN
DOCUMENT, THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE
UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED IN 
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK AND THE LAWS
OF THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF

prepare and execute all necessary instruments to reflect and effect such
termination of the Loan Documents. Agent is hereby authorized to execute all
such instruments on behalf of all Lenders, without the joinder of or further
action by any Lender.

         Section 10.10. Severability. If any term or provision of any Loan

ENFORCE THE FOREGOING WAIVERS, AND (C) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO
ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND
CERTIFICATIONS CONTAINED IN THIS SECTION. AS USED IN THIS SECTION, "SPECIAL

and the lenders named therein (as heretofore amended, the "Original

Agreement and Borrower's and its Subsidiaries' obligations and indebtedness
thereunder, and to induce each Bank Party to enter into this Agreement and to
extend credit hereunder, Borrower represents and warrants to each Bank Party
that the Original Agreement and each "Loan Document" (as defined therein) has
been duly authorized, executed and delivered and is a legal, valid and binding
obligation of each Restricted Person which is a party hereto or thereto,
enforceable in accordance with its terms, except as such enforcement may be
limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights. In furtherance of the
foregoing, BORROWER HEREBY WAIVES IN ALL RESPECTS ANY AND ALL DEFENSES,
SETOFFS, DEDUCTIONS AND COUNTERCLAIMS WHICH MAY EXIST AS OF THE DATE HEREOF
WHICH ANY RESTRICTED PERSON MAY HAVE TO THE PERFORMANCE OF THE OBLIGATIONS AND
PAYMENT OF THE INDEBTEDNESS DESCRIBED THEREIN, including any defense based upon
the invalidity, deficiency, illegality, or unenforceability of the Original 
Agreement, any "Note" or any "Loan Document" (as defined therein), in whole or
in part, including any defense based upon any claim of usury, any bar by any
Law or any statute of limitations or other law of recovery on any of the
obligations or indebtedness described therein, or any defense or excuse for
failure to perform on account of force majeure, act of God, casualty,
impossibility, impracticability, or other defense or excuse whatsoever.

         recovery of approximately $1,500,000-$3,000,000 relating to processing

$25,000,000                   New York, New York              November 25, 1997

         FOR VALUE RECEIVED, the undersigned, Continental Natural Gas, Inc., an
Oklahoma corporation (herein called "Borrower"), hereby promises to pay to the
order of ING (U.S.) CAPITAL CORPORATION (herein called "Revolving Credit
Lender"), the principal sum of Twenty-Five Million Dollars ($25,000,000), or,
if greater or less, the aggregate unpaid principal amount of the Revolving
Credit Loans made under this Revolving Credit Note by Revolving Credit Lender
to Borrower pursuant to the terms of the Credit Agreement (as hereinafter
defined), together with interest on the unpaid principal balance thereof as
hereinafter set forth, both principal and interest payable as herein provided
in lawful money of the United States of America at the offices of the Agent
under the Credit Agreement, 135 East 57th Street, New York, New York or at such
other place within New York County, New York, as from time to time may be
designated by the holder of this Revolving Credit Note.

         This Revolving Credit Note (a) is issued and delivered under that
certain Credit Agreement of even date herewith among Borrower, ING (U.S.)
Capital Corporation, as Agent, and the lenders (including Revolving Credit
Lender) referred to therein (herein, as from time to time supplemented, amended
or restated, called the "Credit Agreement"), and is a "Revolving Credit Note"
as defined therein, (b) is subject to the terms and provisions of the Credit
Agreement, which contains provisions for payments and prepayments hereunder and
acceleration of the maturity hereof upon the happening of certain stated
events, and (c) is secured by and entitled to the benefits of certain Security
Documents (as identified and defined in the Credit Agreement). Payments on this
Revolving Credit Note shall be made and applied as provided herein and in the
Credit Agreement. Reference is hereby made to the Credit Agreement for a
description of certain rights, limitations of rights, obligations and duties of
the parties hereto and for the meanings assigned to terms used and not defined
herein and to the Security Documents for a description of the nature and extent
of the security thereby provided and the rights of the parties thereto.

         For the purposes of this Revolving Credit Note, the following terms
have the meanings assigned to them below:

                  "Base Rate Payment Date" means (i) the last day of each
         March, June, September and December, beginning December 31, 1997, and
         (ii) any day on which past due interest or principal is owed hereunder
         and is unpaid. If the terms hereof or of the Credit Agreement provide
         that payments of interest or principal hereon shall be deferred from
         one Base Rate Payment Date to another day, such other day shall also
         be a Base Rate Payment Date.


                                       1

<PAGE>   88
                  "Eurodollar Rate Payment Date" means, with respect to any
         Eurodollar Loan: (i) the day on which the related Interest Period ends
         (and, if such Interest Period is three months or longer, the
         three-month anniversary of the first day of such Interest Period), and
         (ii) any day on which past due interest or past due principal is owed
         hereunder with respect to such Eurodollar Loan and is unpaid. If the
         terms hereof or of the Credit Agreement provide that payments of
         interest or principal with respect to such Eurodollar Loan shall be
         deferred from one Eurodollar Rate Payment Date to another day, such
         other day shall also be a Eurodollar Rate Payment Date.

         The principal amount of this Note, together with all interest accrued
hereon, shall be due and payable in full on the Revolving Credit Commitment
Termination Date.

         So long as no Default has occurred and is continuing, the Base Rate
Loans from time to time outstanding shall bear interest on each day outstanding
at the Base Rate in effect on such day. On each Base Rate Payment Date Borrower
shall pay to the holder hereof all unpaid interest which has accrued on the
Base Rate Loans to but not including such Base Rate Payment Date. So long as no
Default has occurred and is continuing, each Eurodollar Loan shall bear
interest on each day during the related Interest Period at the related
Eurodollar Rate in effect on such day. On each Eurodollar Rate Payment Date
relating to such Eurodollar Loan, Borrower shall pay to the holder hereof all
unpaid interest which has accrued on such Eurodollar Loan to but not including
such Eurodollar Rate Payment Date. Upon the occurrence and during the
continuance of a Default, the Base Rate Loans and the Eurodollar Loans shall
bear interest on each day outstanding at the Default Rate in effect on such
day, and such interest shall be due and payable daily as it accrues.
Notwithstanding the foregoing provisions of this paragraph: (a) this Revolving
Credit Note shall never bear interest in excess of the Highest Lawful Rate, and
(b) if at any time the rate at which interest is payable on this Revolving
Credit Note is limited by the Highest Lawful Rate (by the foregoing clause (a)
or by reference to the Highest Lawful Rate in the definitions of Base Rate,
Eurodollar Rate, and Default Rate), this Revolving Credit Note shall bear
interest at the Highest Lawful Rate and shall continue to bear interest at the
Highest Lawful Rate until such time as the total amount of interest accrued
hereon equals (but does not exceed) the total amount of interest which would
have accrued hereon had there been no Highest Lawful Rate applicable hereto.

         Notwithstanding the foregoing paragraph and all other provisions of
this Revolving Credit Note, in no event shall the interest payable hereon,
whether before or after maturity, exceed the maximum interest which, under
applicable Law, may be charged on this Revolving Credit Note, and this
Revolving Credit Note is expressly made subject to the provisions of the Credit
Agreement which more fully set out the limitations on how interest accrues
hereon.

         If this Revolving Credit Note is placed in the hands of an attorney
for collection after default, or if all or any part of the indebtedness
represented hereby is proved, established or collected in any court or in any
bankruptcy, receivership, debtor relief, probate or other court proceedings,
Borrower and all endorsers, sureties and guarantors of this Revolving Credit
Note jointly and severally agree to pay reasonable attorneys' fees and
collection costs to the holder hereof in addition to the principal and interest
payable hereunder.

Credit Note hereby severally waive demand, presentment, notice of demand and of
dishonor and nonpayment of this Revolving Credit Note, protest, notice of
protest, notice of intention to accelerate the maturity of this Revolving
Credit Note, declaration or notice of acceleration of the maturity of this
Revolving Credit Note, diligence in collecting, the bringing of any suit

HERETO SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAW), EXCEPT TO THE EXTENT THE SAME ARE GOVERNED
BY APPLICABLE FEDERAL LAW.

or novate) those certain Revolving Credit Notes dated February 28, 1997 made by
Borrower in the aggregate original principal amount of $25,000,000, each of
which is now payable to the order of ING (U.S.) Capital Corporation, as

could cause the Company's actual results to differ materially from those
contemplated contemplated in any forward-looking statements include, among
others, the following:

o    Increased competition in the natural gas marketing industries, including
     effects of: decreasing margins as a result of competitive pressures;
     industry restructuring initiatives; transmission system operation and/or
     administration initiatives; recovery of investments made under traditional
     regulation; nature of competitors entering the industry; and new pricing
     structures.

     physical energy and financial trading activities including, but not limited
     to, price, basis, credit, liquidity, volatility, capacity, transmission,
     currency, interest rate and warranty risks;

o    Risks associated with price risk management strategies intended to
     mitigate exposure to adverse movement in the prices of natural gas on both
     a global and regional basis;

o    Economic conditions including inflation rates and monetary fluctuations;

o    Trade, monetary , fiscal, taxation, and environmental policies of
     government, agencies and similar organizations in geographic areas where

     development or operation of the project;

o    Legal and regulatory delays and other unforeseeable obstacles associated
     with mergers, acquisitions and investments in joint ventures;
