         provisions of SCHEDULE 2.3(B). For each product of inventory, (i) if
         the amount on hand on the Closing Date is greater than the amount of
         the inventory set forth on SCHEDULE 2.3(B), then the difference shall
         result in an increase in the Consideration by the value of such amount,
         and (ii) if the amount on hand on the Closing Date is less than the
         amount set forth on SCHEDULE 2.3(B), then the difference shall result
         in a reduction of the Consideration by the value of such amount.

                  (c) DISPOSITION OF ASSETS. The Consideration shall be reduced
         by an amount equal to any cash or the value of other consideration
         received or to be received by Chevron (unless such other consideration
         is included in the Contributed Businesses or the

                                       15

         Contributed West Texas LPG Pipeline Business) as a result of any
         dispositions of any of the properties or assets that comprise the
         Contributed Businesses or the Contributed West Texas LPG Pipeline
         Business during the period commencing on the date hereof and continuing
         through and including the Closing Date, except for (i) sales of
         inventory, (ii) sales or other dispositions of any of the assets and
         properties that comprise the Contributed Businesses or the Contributed
         West Texas LPG Pipeline Business to the extent subsequently replaced
         with assets or properties of equivalent value prior to the Closing Date
         and (iii) minor sales or dispositions of assets or properties
         comprising the Contributed Businesses or the Contributed West Texas LPG
         Pipeline Business that do not exceed $25,000 individually or $500,000
         in the aggregate.

                  (d) CASUALTY LOSSES. The Consideration shall be (i) reduced by
         the amount of any Casualty Loss that occurs with respect to the
         Contributed Businesses or the Contributed West Texas LPG Pipeline
         Business after the date hereof and prior to the Closing Date, and (ii)
         increased by the amount of any Casualty Loss with respect to the NGC
         Facilities that occurs after the date hereof and prior to the Closing
         Date MULTIPLIED by a fraction (the "CHEVRON CASUALTY LOSS RATIO"), the
         (A) numerator of which is 28 and (B) the denominator of which is 72;
         provided, however, that to the extent that any Casualty Loss occurs,
         the Closing contemplated shall not be affected subject to the
         respective rights of Chevron and NGC under SECTION 12.2(A) and SECTION
         12.3(A), respectively, unless the amount of the Casualty Loss or
         Losses, along with other losses resulting from breaches of
         representations and warranties, causes an aggregate adverse effect on
         either NGC or the Contributed Businesses in an amount in excess of $25
         million.

                  (e) RETAINED ASSETS. The Consideration shall be reduced by the
         Minimum Value or Agreed Value (as applicable) of any Retained Asset
         pursuant to SECTION 2.4.

                  (f) NGBU STORED GAS. The Consideration shall be increased by
         the fair market value of the aggregate amount of natural gas maintained
         by the NGBU in storage as of the Closing date as determined in
         accordance with SCHEDULE 2.3(F).

                  (g) NUG CONTRACT ADJUSTMENTS. The amount of the Newco Note has
         been computed based on an assumed value for the Included NUG Contracts
         (the "NUG VALUE") of $38 million. This value was computed based on such
         contracts being marked to market employing fair market values as of
         April 26, 1996, as more particularly set forth in SCHEDULE 2.3(G). The
         NUG Value shall be recomputed as of the Closing Date, in accordance
         with the terms set forth in such schedule, and the Consideration shall
         be (i) increased by any amount by which the NUG Value as of the Closing
         exceeds $38 million, and (ii) decreased by any amount by which $38
         million exceeds the NUG Value as of the Closing.

                  (h) POST JUNE 1ST ADDITIONAL ADJUSTMENTS. In the event the
         Closing Date occurs after June 1, 1996, the following additional
         adjustments to Consideration shall be made. The Consideration shall

                  (i) be REDUCED by:

                                       16

                  (A) the Net Operating Cash Flow from the Contributed Warren
         Business during the period commencing on June 1, 1996 and continuing
         through and including the Closing Date (the "ADJUSTMENT PERIOD"),
         adjusted to give effect to the Ancillary Agreements relating to the
         Contributed Warren Business during the Adjustment Period, as if each of
         such Ancillary Agreements were in effect as of June 1, 1996; as used
         herein the term "NET OPERATING CASH FLOW" shall mean an amount equal to
         net income (after taxes and excluding out of period items exceeding
         $250,000 individually related to pre-June 1, 1996 operations,) PLUS the
         amount of depreciation and amortization and any write-downs of assets
         for accounting purposes, but only to the extent that such write-downs
         have an earnings but not a cash effect; in the calculation of the Net
         Operating Cash Flow, there shall be no deductions for the severance
         costs which the Chevron Group is required to bear pursuant to the
         provisions of ARTICLE 8 hereof.

                  (B) an amount equal to $952,865 per month to reflect an agreed
         adjustment to the Consideration for the cash flow from the Non Warren
         Businesses for the Adjustment Period (proportionately reduced for each
         portion of a month if the Closing does not occur on the first day of a
         month), and

         (ii) be INCREASED by

                  (A) any amount reflected in net income related to (x) a
         Casualty Loss with respect to the Contributed Warren Business covered
         by paragraph (d) above or (y) a disposition covered by paragraph (c)
         above,

                  (B) the amount of capital expenditures on the Contributed
         Warren Businesses reasonably made by Chevron in accordance with SECTION
         10.7 hereof during the Adjustment Period,

                  (C) interest at the rate of 6% per annum during the Adjustment
         Period on the sum of the Assumed Indebtedness and the Newco Note, as
         adjusted to take into account the Estimated Consideration Adjustment,
         and

                  (D) an amount equal to $580,482.16 times the number of record
         dates for the payment of dividends on NGC Corporation Stock after June
         1, 1996 through the date of Closing.

         Five (5) calendar days prior to the Closing Date, Chevron shall deliver
to NGC (after consultation with NGC) an estimate available at such time (the
"ESTIMATED CONSIDERATION ADJUSTMENT"), which estimate shall be used to determine
the consideration due to Chevron under SECTIONS 2.1(B) AND 2.1(C). If the
Estimated Consideration Adjustment results in an aggregate increase in the
Consideration due to Chevron, then at Closing the amount of the Estimated
Consideration Adjustment shall be added to the outstanding principal balance of
the Newco Note. If the Estimated Consideration Adjustment results in an
aggregate decrease in the Consideration due Chevron of $138.4 million or less,
then at Closing the principal amount of the Newco Note shall be reduced by an
amount equal to the Estimated Consideration Adjustment. If the Estimated
Consideration Adjustment results in an aggregate decrease in the Consideration
due

                                       17

Chevron that is equal to or greater than $138.4 million, then the Newco Note
shall be canceled and the remainder, if any, of the Estimated Consideration
Adjustment shall be applied to reduce the outstanding principal balance of the
Assumed Indebtedness.

         Following the Closing, further Consideration Adjustments shall be made
as required pursuant to SECTIONS 15.3, 15.4, 15.5 AND 15.6.

         2.4 ADJUSTMENTS FOR RETAINED ASSETS. If for any good and sufficient
reason, including Preferential Rights, Requisite Regulatory Approvals, or the
discovery of a sale or other transfer prior to the date of this Agreement,
either party determines, in good faith, that a Contributing Party is unable (or
in the case of contracts, that it is impractical) to transfer to Newco an asset
or property included in the Contributed Businesses or the Contributed West Texas
LPG Pipeline Business or is unable to transfer to Newco such asset or property
without a significant loss of use thereof by the Surviving Corporation, such
party shall promptly communicate such fact to the other party and consult with
such party concerning such impediment. If Chevron and NGC are unable to agree on
a solution to overcome such impediment (which could include alternative means of
transferring value effectively), the Contributing Party shall retain such asset
or property (whether one or more, the "RETAINED ASSET") and the net value which
cannot be effectively transferred. In such case, Chevron and NGC shall endeavor
in good faith to determine the fair value of the Retained Asset (net of the
economic value which has been transferred) for purposes of the Estimated
Consideration Adjustment. If the parties agree on such fair value (the "AGREED
VALUE"), they shall document their agreement in writing, which shall provide,
among other things, the Agreed Value the parties ascribed to the Retained Asset.
The Agreed Value set forth in such written agreement shall be final and binding
on the parties. If Chevron and NGC are unable to agree on the fair value of the
Retained Asset, then not less than five (5) Business Days prior to the Closing
Date, Chevron shall provide NGC with a document providing a reasonable estimate
of the fair value of the Retained Asset (the "MINIMUM VALUE") and the basis for
determining such value. The parties acknowledge and agree that the Minimum Value
shall be binding on the parties hereto for the purpose of Closing, but shall be
subject to adjustment after Closing as provided by SECTION 15.5. To the extent
that a Contributing Party does not transfer a Retained Asset pursuant to this
SECTION 2.4, the Closing contemplated hereby shall not be affected, subject to
NGC's rights under SECTION 12.3(A) in the event that NGC's reasonable estimate
of the fair value of the Retained Asset, along with other losses and costs
resulting from breaches of representations and warranties by Chevron, exceed $25
million in the aggregate. The parties hereto acknowledge that the Minimum Value
shall not be binding on NGC in determining a reasonable estimate of the fair
value of the Retained Asset for the purposes of the immediately preceding
sentence.

standing in each jurisdiction in which the nature of the business transacted by

amendments thereto, and all such documents are now in effect and are complete

conducted on the date of this Agreement, except where the failure to have such

                  (a) NGC has furnished Chevron with a true and complete copy of
         the NGC SEC Documents. The NGC SEC Documents are all the documents
         (other than preliminary material) that Trident Holding and NGC have
         been required to file with the SEC since January 1, 1995. As of its
         filing date (and, with respect to any registration statement, the date
         on which it or any post-effective amendment was declared effective),
         each NGC SEC Document was in compliance, in all material respects, with
         the applicable requirements of the Securities Act and the Exchange Act,
         contained no untrue statement of a material fact and did not omit any
         statement of a material fact required to be stated therein or necessary
         to make the statements therein, in light of the circumstances under
         which they were made, not misleading. The financial statements of NGC,
         Clearinghouse, Trident NGL, Inc., and Trident Holding included in the
         NGC SEC Documents complied, at the time of filing with the SEC (and,
         with respect to any

                                       23

         registration statement, at the time it was declared effective), as to
         form, in all material respects, with applicable accounting requirements
         and the published rules and regulations of the SEC with respect
         thereto, were prepared in accordance with generally accepted accounting
         principles applied on a consistent basis during the periods involved
         (subject, in the case of unaudited statements, to the omission of
         certain footnotes) and fairly present, in all material respects
         (subject, in the case of the unaudited statements, to normal, recurring
         year-end audit adjustments) the consolidated financial position of NGC,
         Clearinghouse, Trident NGL, Inc. and Trident Holding, as applicable, as
         of the dates thereof and the consolidated results of their operations
         for the periods presented. Except as set forth on SCHEDULE 4.24, since
         December 31, 1995, there has not been any change in the business,
         assets, financial condition or results of operation of NGC or any of
         its Subsidiaries, which in any case would, either individually or in
         the aggregate, reasonably be expected to have a Material Adverse Effect
         on NGC or on the ability of the Surviving Corporation to perform its
         obligations under the Ancillary Agreements, other than changes
         resulting from industry-wide conditions or general economic conditions
         affecting the industry in which NGC carries on its business.

                  (b) NGC has made available to Chevron true and complete copies
         of all internal audit reports that have been issued by NGC or any of
         its predecessors or Subsidiaries or Significant Affiliates during the

         associated with or otherwise covering the NGC Assets have or had any
         material weaknesses or its or their accounting records contained or
         could contain any material errors. NGC's public accountants have not
         issued any audit reports or other reports on internal controls which
         indicate that the internal controls associated with or otherwise
         covering any of the NGC Assets have or had any material weaknesses or
         that the accounting records associated with or otherwise covering any
         of the NGC Assets contained or could contain any material errors.

Material Adverse Effect on NGC or (b) judgments, decrees, injunctions, rules or
orders of any Governmental Entity or arbitrator outstanding against NGC or any

NGC or on the ability of the Surviving Corporation to perform its obligations
under the Ancillary Agreements. Except (x) as disclosed

                              ENVIRONMENTAL MATTERS

         6.1 CHEVRON'S ENVIRONMENTAL INDEMNITY.

                  (a) Subject to the limitations set forth in ARTICLE 14,
         Chevron agrees to and shall indemnify and hold the NGC Indemnitees
         harmless against and from any and all Losses from:

                           (i) the Release of Hazardous Materials in, on, at, or
                  from the Chevron Facilities occurring prior to the Closing
                  Date in violation of any Environmental and Safety Law;

                           (ii) liability to third parties as a result of
                  Releases of Hazardous Materials in, on, at, or from the
                  Chevron Facilities occurring prior to the Closing Date;

                           (iii) the designation of the Surviving Corporation
                  under CERCLA or any analogous state statute as a potentially
                  responsible party for, or any private party action relating
                  to, onsite or offsite disposal of Hazardous Materials, to the
                  extent such substances were generated at or disposed on the
                  Chevron Facilities prior to the Closing Date;

                           (iv) fines or penalties for which the Surviving
                  Corporation may become liable with respect to any violation of
                  Environmental and Safety Laws at a Chevron Facility occurring
                  prior to the Closing Date;

                           (v) a failure of a Contributing Party to operate a
                  Chevron Facility as of the Closing Date in substantial
                  compliance with (i) all applicable Environmental and Safety
                  Laws, (ii) all terms and conditions of Environmental Permits,
                  and (iii) all environmental orders and consent agreements in
                  effect and applicable to the Chevron Facility;

                           (vi) the failure of a Contributing Party or an
                  operator of a Chevron Facility to have all the Environmental
                  Permits required by Environmental and Safety Laws to operate
                  the Chevron Facilities as they are being operated as of the
                  Closing Date; and

                           (vii) environmental conditions that exist on the
                  Chevron Facilities as of the Closing Date that would, solely
                  with the lapse of time or the giving of notice or both,
                  subject the Surviving Corporation to any responsibility for
                  any current remediation obligations under any applicable
                  Environmental and Safety Laws.

                  (b) Subject to the provisions of SECTION 6.4 below, in the
         event that the Surviving Corporation (or any Affiliate) sells,
         transfers or otherwise conveys any of the assets or properties
         comprising the Contributed Businesses to a party that is not an

                                       39

         Affiliate of the Surviving Corporation (the "PURCHASER"), then the
         Surviving Corporation shall be entitled to indemnification pursuant to
         the indemnity obligations set forth in paragraph (a) of this SECTION
         6.1 for Losses that result from an indemnity covering environmental
         matters granted by the Surviving Corporation (or any Affiliate) to the
         Purchaser in connection with the transfer of such asset or property to
         the Purchaser, but only (x) with respect to claims asserted by such
         Purchaser relating to or during the period of the Purchaser's ownership
         and (y) to the extent that the Surviving Corporation would have been
         entitled to such indemnification had it (instead of the Purchaser) been
         the owner and asserted such claim for indemnification against Chevron
         pursuant to SECTION 6.1(A) hereof; provided, however, that any claims
         by the Surviving Corporation for indemnification under this paragraph
         (b) shall be subject, along with any other Discrete Claims made under
         SECTION 6.1(A) or ARTICLE 14, to the limitations set forth in SECTION
         14.4; and provided further, that in no event shall this SECTION 6.1(B)
         be construed to provide any Purchaser with any indemnification rights
         hereunder from either Chevron or the Surviving Corporation, nor shall
         Chevron or the Surviving Corporation be in any way liable or otherwise
         obligated to any Purchaser under this SECTION 6.1.


         6.2      SURVIVING CORPORATION'S ENVIRONMENTAL INDEMNITY.

                  (a) Subject to the limitations set forth in ARTICLE 14, NGC,
         for and on behalf of the Surviving Corporation, agrees that the
         Surviving Corporation shall indemnify and hold the Chevron Indemnitees
         harmless against and from any and all Losses from:

                           (i) the Release of Hazardous Materials in, on, at, or
                  from the NGC Facilities or Former NGC Facilities occurring
                  prior to the Closing Date in violation of any Environmental
                  and Safety Law;

                           (ii) liability to third parties as a result of
                  Releases of Hazardous Materials in, on, at, or from the NGC
                  Facilities or Former NGC Facilities occurring prior to the
                  Closing Date;

                           (iii) the designation of the Surviving Corporation
                  under CERCLA or any analogous state statute as a potentially
                  responsible party for, or any private party action relating
                  to, onsite or offsite disposal of Hazardous Materials, to the
                  extent such substances were generated at or disposed on the
                  NGC Facilities or Former NGC Facilities prior to the Closing
                  Date;

                           (iv) fines or penalties for which the Surviving
                  Corporation may become liable with respect to any violation of
                  Environmental and Safety Laws at an NGC Facility occurring
                  prior to the Closing Date;

                           (v) a failure of NGC or any of its Subsidiaries or
                  Equity Affiliates to operate an NGC Facility as of the Closing
                  Date in substantial compliance with (i) all applicable
                  Environmental and Safety Laws, (ii) all terms and conditions
                  of Environmental Permits, and (iii) all environmental orders
                  and consent agreements in effect and applicable to the NGC
                  Facility;

                                       40

                           (vi) the failure of NGC or any of its Subsidiaries or
                  Equity Affiliates or an operator of an NGC Facility to have
                  all the Environmental Permits required by Environmental and
                  Safety Laws to operate the NGC Facilities as they are being
                  operated as of the Closing Date; and

                           (vii) environmental conditions that exist on the NGC
                  Facilities or Former NGC Facilities as of the Closing Date
                  that would, solely with the lapse of time or the giving of
                  notice or both, subject the Surviving Corporation to any
                  responsibility for any current remediation obligations under
                  any applicable Environmental and Safety Laws.

         6.3 FURTHER LIMITATION ON RECOVERY FOR LOSSES. Chevron and NGC agree
that no Losses suffered by the Surviving Corporation as a result of Releases
from and after the Closing Date shall be the subject of any payments to or from
Chevron under the provisions of ARTICLE 14.

         6.4 PREVIOUSLY GRANTED INDEMNITIES. The parties hereby agree that the
transactions contemplated hereby, including, without limitation, the
contribution of the assets comprising the Contributed Businesses to Newco or the
Merger, shall not terminate or otherwise affect any indemnity granted prior to
the date hereof by NGC or any Affiliate thereof or any predecessor thereto in
favor of any Contributing Party or of any Contributing Party in favor of NGC or
any Affiliate thereof or any predecessor thereto covering environmental losses
or claims relating to any asset or property comprising a part of the Contributed
Businesses or the NGC Assets (as the case may be), notwithstanding the fact that
such indemnity by its terms would otherwise terminate upon the contribution of
such asset to Newco or the Merger.

         6.5 SURVIVAL. Notwithstanding any other provisions of this Agreement,
the indemnities set forth in SECTIONS 6.1 and 6.2 shall survive for a period
commencing on the Closing Date and continuing through and including August 30,
2001, and shall terminate at the expiration of such period, except in the case
of (i) Third Party Claims or Use Claims for which a notice complying with the
terms of SECTION 14.5(A) and SECTION 14.7, respectively, and covering a Discrete
Claim that has previously occurred is received on or prior to August 30, 2001 or
(ii) Environmental Remediation Claims for which a notice complying with the
terms of SECTION 14.6(A) and covering a Discrete Claim that has previously
occurred is received on or prior to August 30, 2001.

                                      TAXES

         7.1      TAX FILINGS AND REPRESENTATIONS.

                  (a) The parties believe that (i) the contribution of
         Contributed Businesses and the Contributed West Texas LPG Pipeline
         Business by the Chevron Group to Newco will be treated as a transaction
         described in Section 351 of the Code and Chevron will be afforded
         nonrecognition treatment, in part, under such section, and (ii) the
         Merger will constitute a "reorganization" within the meaning of Section
         368(a)(1)(A) of the Code, with the result, in part, of affording
         nonrecognition treatment to NGC and its

                                       41

         stockholders with respect to the transfers and exchanges occurring in
         the Merger. Each party agrees that it will file its Tax Returns
         consistent with these tax consequences and the allocation contemplated
         by SECTION 7.2(D).

                  (b) NGC represents that it has no present plan or intention
         for the Surviving Corporation (a) to enter into a transaction or series
         of transactions that would terminate the existence of Surviving
         Corporation, (b) or its Subsidiaries to dispose of the assets and
         properties comprising the Contributed Businesses and the Contributed
         West Texas LPG Pipeline Business, other than dispositions in the
         ordinary course of business operations (including dispositions to
         rationalize the various operations acquired by Newco), and dispositions
         to members of the Surviving Corporation Group or to partnerships
         wholly-owned by such members and/or Chevron (or its Affiliates), or (c)
         to redeem or otherwise reacquire any stock or indebtedness to be issued
         in the Combination (other than with respect to Surviving Corporation
         Stock acquired from employees not referred to in SECTION 12.2(D)
         through the NGC Plans and Savings Plan or the exercise of rights to pay
         or call indebtedness as allowed by its terms).

         7.2 TAX RESPONSIBILITIES. Chevron will be responsible for and shall pay
any and all Chevron Taxes. Chevron represents that each transferor of a part of
the Contributed Businesses and the Contributed West Texas LPG Pipeline Business
is a member of the Chevron Group. Surviving Corporation shall be responsible for
and shall pay any and all Surviving Corporation Taxes. Chevron shall have no
liability whatsoever with regard to Surviving Corporation Taxes or NGC
Stockholder Taxes, except as otherwise provided in SECTION 7.6. Surviving
Corporation and the NGC stockholders shall have no liability whatsoever with
regard to Chevron Taxes, except as otherwise provided in SECTION 7.6.

                  (a) The term "CHEVRON TAXES" or "CHEVRON TAX" shall mean any
         and all Taxes imposed upon, paid, payable, or required to be collected
         by any or all of Chevron and the Chevron Group for any and all taxable
         years or periods. The term "CHEVRON TAXES" or "CHEVRON TAX" also
         includes any ad valorem Tax imposed upon assets held by Chevron or the
         Chevron Group and those Taxes identified as such in clause (iii) of
         SECTION 7.2(D). Newco and its Subsidiaries, if any, shall be treated as
         members of the Chevron Group through the Closing Date.

                  (b) The term "SURVIVING CORPORATION TAXES" or "SURVIVING
         CORPORATION TAX" shall mean (i) assuming the Merger is effected, any
         and all Taxes imposed upon, paid, payable or required to be collected
         by any or all of NGC, the NGC Group, Clearinghouse, Trident NGL, Inc.
         and Trident Holding for any and all taxable years or periods ending on
         or before the Closing Date ("NGC TAXES") and (ii) for any and all
         taxable years or other periods beginning on or after the Closing Date,
         any and all Taxes imposed upon, paid, payable or required to be
         collected by Surviving Corporation and the Surviving Corporation Group
         and those Taxes identified as such in clause (iii) of SECTION 7.2(D).
         The term "SURVIVING CORPORATION TAXES" or "SURVIVING CORPORATION TAX"
         also includes any ad valorem Tax imposed upon assets held by NGC or
         Surviving Corporation, respectively.


                                       42

                  (c) The term "NGC STOCKHOLDER TAXES" or "NGC STOCKHOLDER TAX"
         shall mean any and all taxes paid, payable or required to be collected
         by any and all of the NGC Stockholders. The term "NGC STOCKHOLDERS"
         shall mean any and all of the stockholders of NGC or Surviving
         Corporation, other than Chevron.

                  (d)      For purposes of this SECTION 7.2:

                           (i) In the case of any Tax attributable to a taxable
                  year or other period that includes or ends on the Closing
                  Date, such Tax shall be allocated between the portion of such
                  taxable year or other period ending on the Closing Date and
                  the portion beginning after the Closing Date by allocating all
                  items of income, loss, deduction, credit, payroll, premium,
                  capital, gross receipts, sales, and the like between the
                  portion ending on and the portion beginning after the Closing
                  Date based on an interim closing of the books as of 11:59 p.m.
                  on the Closing Date. The parties hereto agree that on the
                  Closing Date they shall not cause Newco or its Subsidiaries to
                  participate in any transaction outside of the ordinary course
                  of business, other than the transactions contemplated by this
                  Agreement.

                           (ii) Provided, however, that if any such item cannot
                  reasonably be determined on the basis of an interim closing of
                  the books, and except to the extent otherwise required by
                  applicable law, then such item shall be allocated based on the
                  number of days in the period ending on the Closing Date and
                  the number of days in the period beginning after the Closing
                  Date.

                           (iii) Notwithstanding anything to the contrary in
                  this SECTION 7.2, Chevron shall be responsible for all
                  transfer Taxes and other Taxes relating to the contribution of
                  the Contributed Businesses and the Contributed West Texas LPG
                  Pipeline Business to Newco (which Taxes shall be "CHEVRON
                  TAXES"), and the Surviving Corporation shall be responsible
                  for all transfer Taxes and other Taxes relating to the Merger
                  (which Taxes shall be "SURVIVING CORPORATION TAXES").

                           (iv) Notwithstanding anything to the contrary in this
                  SECTION 7.2, any ad valorem Tax relating to any asset
                  comprising a part of the Contributed Businesses or the
                  Contributed West Texas LPG Pipeline Business that is
                  attributable to a tax period that includes the Closing Date
                  shall be allocated as a Chevron Tax or a Surviving Corporation
                  Tax based on the number of days that each such party owned
                  such asset during such period.

                           (v) Notwithstanding anything to the contrary in this
                  SECTION 7.2, all Taxes imposed upon, paid, payable, or
                  required to be collected by Newco or its Subsidiaries while it
                  is a member of the Chevron Group, including any consolidated
                  or combined liabilities of the Chevron Group (including,
                  without limitation, Tax liabilities incurred by reason of
                  Treasury Regulations ss.1.1502-6) shall be considered Chevron
                  Taxes.

                  (e) Subject to the provisions of SECTIONS 7.1 (A) and 7.3
         hereof, (i) Chevron shall be responsible, at its sole cost and expense,
         for the preparation, maintenance and

                                       43

         filing of all tax returns, information returns, reports, statements,
         and related documents (hereinafter collectively referred to as "TAX
         RETURNS") relating to Chevron Taxes, and (ii) Surviving Corporation or
         NGC shall be responsible, at its sole cost and expense, for the
         preparation and filing of all Tax Returns relating to Surviving
         Corporation Taxes or NGC Taxes. All Tax Returns required to be filed by
         Chevron ("CHEVRON RETURNS") have been or will be filed at the times and
         in the manner prescribed by law. All Tax Returns required to be filed
         by Surviving Corporation or NGC ("SURVIVING CORPORATION RETURNS") have
         been or will be filed by Surviving Corporation or NGC at the times and
         in the manner prescribed by law.

         7.3 RECORDS AND ASSISTANCE. Subject to the reimbursement of reasonable
out-of-pocket expenses, the parties hereto will provide each other such records
and assistance as may reasonably be requested by any of them in connection with
the preparation of any Tax Return, and audit or other examination by any taxing
authority, and any judicial and administrative proceedings relating to liability
for Taxes (including, without limitation, any additions to or refunds of Taxes).
Surviving Corporation shall retain all records delivered to it by Chevron in the
Combination relating to Chevron Taxes for the longer of (i) six (6) years after
the September 15 following the end of the taxable year to which the Tax Audit
with respect to Chevron Taxes relates or (ii) upon notice from Chevron, with
respect to any Tax Audit, that the statute of limitations has been extended
beyond six (6) years after the September 15 following the end of the taxable
year to which the Tax Audit with respect to Chevron Taxes relates, until the end
of such extension period. Chevron shall reimburse Surviving Corporation for any
reasonable out-of-pocket expenses incurred by it with respect to such record
retention to the extent of the excess, if any, of the expenses attributable to
the period described in SECTION 7.3(II), over the expenses attributable to the
period described in SECTION 7.3(I). Surviving Corporation shall secure the same
access to records and assistance and the same record retention described in the
immediately preceding sentence in the event that Surviving Corporation disposes
of any of the Contributed Businesses or the Contributed West Texas LPG Pipeline
Business. All information provided pursuant to this ARTICLE 7 shall be held in
confidence and shall not be disclosed to persons other than requesting parties
hereto for any reason whatsoever, except to the extent that such disclosure is
required in order to effect the intent of this ARTICLE 7 or such disclosure is
required by law.

         7.4 TAX SHARING AGREEMENTS. This Agreement supersedes and terminates
any and all other tax sharing, tax allocation, and other similar agreements,
policies, and arrangements previously in effect with respect to (i) all or any
of Newco or its Subsidiaries, on the one hand, and (ii) any or all of the other
members of the Chevron Group, on the other hand. Except as expressly provided in
this Agreement, neither Newco nor its Subsidiaries shall have any obligation,
directly or indirectly, to make any payment to or on behalf of any other member
of the Chevron Group in respect of any Tax or refund of Tax for any taxable
year.

         7.5 TAX AUDITS. With respect to the taxable years of Chevron, NGC,
Newco, or Surviving Corporation not yet audited by, currently under audit by, or
under protest or appeal with, any taxing authority:

                  (a) Subject to SECTION 7.5(D), Chevron, at its sole cost and
         expense, shall control the conduct of all stages of any audit or other
         judicial or administrative

                                       44

         proceeding (collectively referred to as a "TAX AUDIT") with respect to
         Chevron Taxes. Surviving Corporation, at its sole cost and expense,
         shall control the conduct of all Tax Audits with respect to Surviving
         Corporation Taxes.

                  (b) Chevron shall give prompt notice to Surviving Corporation
         of any Tax adjustment proposed in writing pursuant to any Tax Audit
         controlled by Chevron (i) that may be borne by the Surviving
         Corporation (or any of its Subsidiaries) or have an adverse effect on
         either of the Contributed Businesses or the Contributed West Texas LPG
         Pipeline Business or (ii) that could give rise to an indemnification
         under SECTION 7.6(A). Upon Surviving Corporation's reasonable request,
         Chevron shall discuss with Surviving Corporation and Surviving
         Corporation's counsel the position that Chevron intends to take
         regarding any issue concerning such Tax Audit, and shall afford
         Surviving Corporation and its counsel a reasonable opportunity to
         participate, at Surviving Corporation's sole cost and expense, in the
         conduct of that portion of any such Tax Audit relating to such claim
         (including, without limitation, participation in conferences and
         subsequent non-judicial proceedings with the taxing authority and
         submission of pertinent materials in support of Chevron's position).

                  (c) Surviving Corporation shall give prompt notice to Chevron
         of any Tax adjustment proposed in writing pursuant to any Tax Audit
         controlled by Surviving Corporation (i) that could give rise to a claim
         against Chevron under this Agreement or (ii) that could give rise to an
         indemnification under SECTION 7.6(B). Upon Chevron's reasonable
         request, Surviving Corporation shall discuss with Chevron and Chevron's
         counsel the position that Surviving Corporation intends to take
         regarding any issue concerning such Tax Audit, and shall afford Chevron
         and its counsel a reasonable opportunity to participate, at Chevron's
         sole cost and expense, in the conduct of that portion of any such Tax
         Audit relating to such claim (including, without limitation,
         participation in conferences and subsequent non-judicial proceedings
         with the taxing authority and submission of pertinent materials in
         support of Surviving Corporation's position).

                  (d) In the case of a Tax Audit that Chevron believes could
         give rise to an indemnity under clause (iii) of SECTION 7.6(B) (and so
         much of clause (iv) as relates thereto), Chevron shall give prompt
         notice to Surviving Corporation in writing as soon as reasonably
         possible after initial discussions with or receipt of a written
         communication from any representative of a taxing authority regarding
         any issues that could give rise to a claim for such indemnity (the
         "AUDIT ISSUES"). Chevron shall at all times take positions in the Tax
         Audit, with respect to the Audit Issues, consistent with those advanced
         by Surviving Corporation in writing and shall afford Surviving
         Corporation and its counsel a reasonable opportunity to participate, at
         Surviving Corporation's sole cost and expense, in the conduct of that
         portion of any Tax Audit relating to such claim (including, without
         limitation, participation in conferences and subsequent non-judicial
         proceedings with the taxing authority and submission of pertinent
         materials in support of Chevron's position). Chevron shall appeal (to
         the extent legally allowable) all decisions inconsistent with the
         positions advanced by Surviving Corporation with respect to such Audit
         Issues that could result in indemnification under SECTION 7.6(B)(III),
         unless otherwise agreed by Chevron and Surviving Corporation. If
         Surviving Corporation believes a decision of a court of

                                       45

         law with respect to such Audit Issues should be appealed, but Chevron
         disagrees, Surviving Corporation shall reimburse Chevron for all costs
         and expenses related to the Audit Issues of any such appeal.

         7.6      TAX INDEMNITY.

                  (a) With the exception of increases in Chevron Taxes described
         in clause (ii) of SECTION 7.6(B) hereof, Chevron shall indemnify,
         protect, save, and keep harmless Surviving Corporation and its
         Subsidiaries and their respective officers, directors, employees,
         agents and Affiliates from and against (i) any and all Chevron Taxes
         directly incurred by any of them in connection therewith, and (ii) any
         and all Surviving Corporation Taxes payable for taxable periods
         beginning on or after the Closing Date, but only to the extent (if any)
         of the amount of any such Surviving Corporation Tax that is caused by
         or arises from a breach or other violation of, or inaccuracy or
         incompleteness of, any of the covenants, warranties, or representations
         of Chevron set forth in the last sentence of SECTION 7.1(A) AND IN
         SECTION 7.2 hereof, and (iii) all reasonable costs and expenses
         (including, without limitation, court costs and professional fees)
         incurred by Surviving Corporation (or its Subsidiaries) in connection
         with an indemnity provided in this SECTION 7.6(A).

                  (b) With the exception of increases in Surviving Corporation
         Taxes described in clause (ii) of SECTION 7.6(A) hereof, Surviving
         Corporation shall indemnify, protect, save, and keep harmless Chevron
         and its Subsidiaries and their respective officers, directors,
         employees, agents and Affiliates from and against (i) any and all
         Surviving Corporation Taxes directly incurred by any of them, (ii) any
         and all Chevron Taxes payable for taxable periods ending on or after
         the Closing Date, but only to the extent (if any) of the amount of any
         such Chevron Tax that is caused by or arising from a breach or other
         violation of, or inaccuracy or incompleteness of, any of the covenants,
         warranties, or representations of NGC set forth in the last sentence of
         SECTION 7.1(A) AND IN SECTION 7.2 hereof, (iii) provided that SECTION
         7.5(D) has been complied with, any and all Chevron Taxes payable for
         the taxable period that includes the Closing Date that is caused by or
         arises from the inaccuracy of any of the representations of NGC set
         forth in SECTION 7.1(B) hereof; and (iv) all reasonable costs and
         expenditures (including, without limitation, court costs and
         professional fees) incurred by Chevron (or its Subsidiaries) in
         connection with any indemnity provided in this SECTION 7.6(B).

                  (c) Any payments required to be made pursuant to this SECTION
         7.6 (a "TAX INDEMNITY PAYMENT") shall be made, whether or not the
         amount is contested under SECTION 7.6(D), on the latest of (i) twenty
         (20) Business Days after written demand by the indemnified party, which
         written demand shall include a statement (the "INDEMNITY STATEMENT")
         setting forth in reasonable detail the good faith computations of the
         indemnification hereunder and the procedure for contesting the amount
         (including the timing of the written notice thereof) set forth in
         SECTION 7.6(D) hereof, (ii) five (5) Business Days before the last day
         prescribed by law on which the payment of the indemnified Tax in
         question may be made to the relevant taxing authority without the
         imposition of any penalty, interest, addition to Tax, or other late
         charge by the taxing authority, or (iii) in the case of an Indemnity
         Payment under clause (iii) of SECTION 7.6(B)

                                       46

         or clause (iv) of SECTION 7.6(B) to the extent it relates to an
         Indemnity Payment under such clause (iii), the later of ten days after
         (A) if Chevron and the Surviving Corporation agree that a Tax Indemnity
         Payment is required under SECTION 7.6(B)(III), the date judgment by a
         Circuit Court of Appeals or the Supreme Court of the United States
         becomes final and unappealable, or (B) otherwise, after the decision of
         the Arbitrator pursuant to the procedures in SECTION 7.6(D) as to
         whether an Indemnity Payment is required pursuant to Section
         7.6(b)(iii).

                  (d) Chevron or Surviving Corporation may contest the amount of
         any Tax Indemnity Payment set forth on an Indemnity Statement within
         120 Business Days of the receipt of the Tax Indemnity Statement by
         written notice; PROVIDED, HOWEVER, to the extent that any Tax Indemnity
         Payment set forth on an Indemnity Statement relates to SECTION
         7.6(B)(III) or SECTION 7.6(B)(IV) (as it relates to an Indemnity
         Payment under SECTION 7.6(B)(III), such 120 day period for contesting
         an amount on a Tax Indemnity Statement shall begin on the later of the
         date of a final settlement with the U.S. Government or the date
         judgment by a trial court, a Circuit Court of Appeals or the Supreme
         Court of the United States becomes final and unappealable, unless
         otherwise agreed by Chevron and Surviving Corporation. If Surviving
         Corporation or Chevron contests such amount during the 120 day period,
         Chevron and Surviving Corporation, at their joint expense, shall select
         and engage an independent nationally-recognized public accounting or
         law firm (an "ARBITRATOR") (which shall in no event be the auditors for
         or representatives of either Chevron or Surviving Corporation at the
         time of selection) to redetermine the amount of the Chevron Tax or
         Surviving Corporation Tax so contested, which redetermination shall be
         binding and conclusive. If Chevron and Surviving Corporation cannot
         agree on one (1) jointly chosen Arbitrator, then each shall select one
         (1) Arbitrator at its own cost and expense. Such two (2) Arbitrators
         selected by Chevron and Surviving Corporation shall then select a third
         Arbitrator (other than themselves) to redetermine the amount of the
         Chevron Tax or Surviving Corporation Tax so contested, which
         redetermination shall be binding and conclusive. If such Arbitrator
         redetermines that the amount of the Tax Indemnity Payment is less than
         the amount shown in the Indemnity Statement so contested, then (i) the
         indemnified party shall refund such difference (together with any
         interest on such difference that the indemnified party has collected
         from the indemnifying party) to the indemnifying party within fifteen
         (15) days after the indemnified party has received written notice of
         the amount determined by said Arbitrator or (ii) in the case of a Tax
         Indemnity Payment required under SECTION 7.6(B)(III), Surviving
         Corporation shall pay Chevron the lesser of (A) the amount shown on the
         Indemnity Statement with respect to such Tax Indemnity Payment or (b)
         the amount determined by the Arbitrator.

                  (e) If any amount payable pursuant to this SECTION 7.6 is not
         paid when due, then such amount shall bear interest at the lesser of
         (i) the highest lawful rate for the period of time that the amount
         remains unpaid, or (ii) the rate of interest accruing under Section
         6621(a)(2) of the Code for the period of time that the amount remains
         unpaid.

                  (f) Any Tax Indemnity Payment required to be made pursuant to
         this SECTION 7.6, other than Tax Indemnity Payments required to be made
         pursuant to SECTION 7.6(B)(III), shall be increased or reduced, as
         appropriate, to take into account the tax

                                       47

         consequences to the payee, if any, of (i) such Tax Indemnity Payment to
         the indemnified party and (ii) expenditures made by the indemnified
         party that are being reimbursed by such Tax Indemnity Payment.

                  (g) Any Tax Indemnity Payment required to be made pursuant to
         SECTION 7.6(B)(III) at the time stated in SECTION 7.6(C)(III) shall be
         increased by an amount of interest at Chevron's effective borrowing
         rate as in effect from time-to-time from the date on which Chevron
         actually paid the Tax for which the Tax Indemnity Payment is made until
         the date when payment is due pursuant to SECTION 7.6(C)(III).

         7.7 SURVIVAL. Notwithstanding any other provisions of this Agreement,
all of the warranties, representations, covenants and agreements set forth in
this ARTICLE 7 with respect to each Tax liability and any and all Tax Returns,
audits, examinations, and proceedings relating thereto shall survive the Closing
for a period ending 90 days after the latest of (i) the lapse of the applicable
period for assessment, imposition, or refund of Tax (as the same may be
extended) with respect thereto, (ii) receipt of the notice described in SECTIONS
7.5(B)(II) or 7.5(C)(II) hereof, (iii) the lapse of the applicable period for
assessment, imposition or refund of Tax (as the same may be extended) relating
to the taxable year or period in which any Tax savings are actually realized
pursuant to SECTION 7.6(F) or (iv) the determination by the Arbitrator referred
to in SECTION 7.6(D). This SECTION 7.7 shall not prejudice the survival of any
other warranty, representation or covenant under this Agreement.

         7.8      INDEMNITY FOR NGC TAX LOSSES.

                  (a) Surviving Corporation shall pay to Chevron the amount of
         any NGC Tax Loss (an "NGC TAX LOSS PAYMENT"). The term "NGC Tax Loss"
         shall mean the "Unadjusted NGC Tax Loss" (defined in SECTION 7.8(B))
         adjusted as provided in SECTION 7.8(C).

                  (b) The term "Unadjusted NGC Tax Loss" shall mean the excess,
         if any, of (i) any and all NGC Taxes paid by Surviving Corporation on
         or after the Closing Date (other than (x) Taxes paid with final returns
         or statements for taxable periods ending in or after 1995 that are
         filed after the Closing Date (other than amended returns or amended
         statements) or (y) Taxes for tax periods ending on or after the Closing
         Date) ("RELEVANT NGC TAXES"), over (ii) the present value (as of the
         date of the payment of the Relevant NGC Taxes) of the tax savings or
         refunds, if any, reasonably expected to the Surviving Corporation as a
         result of the payment of the Relevant NGC Taxes or the adjustments
         resulting in such Relevant NGC Taxes, in either case, for any taxable
         period of NGC (or its Subsidiaries) or Surviving Corporation (or its
         Subsidiaries). This present value shall be computed using NGC's
         effective borrowing rate as in effect from time-to-time. Surviving
         Corporation shall prepare and provide to Chevron a schedule setting
         forth the amount of the expected Tax savings or refunds and shall
         update such schedule no less often than once each calendar year.

                  (c) The Unadjusted NGC Tax Loss shall be adjusted in the
         following manner to compute the NGC Tax Loss. The Unadjusted NGC Tax
         Loss shall be reduced (but not below zero) by up to $7.5 million (as
         agreed by the Parties), (which after such

                                       48

         reduction shall be referred to as the "GROSS TAX LOSS"). For purposes
         hereof, an NGC Tax Loss will have occurred at each time that the amount
         of the Gross Tax Loss increases, for example, without limitation, upon
         a decrease in the present value of the reasonably expected Tax savings
         or refunds taken into account in the previous determination of the
         Gross Tax Loss as a result of the reasonable expectation of either a
         delay in achieving or a failure to achieve such Tax savings or refunds.
         The amount of the NGC Tax Loss incurred at each such time shall be the
         product of the increase in the Gross Tax Loss at such time and the
         fraction described in SECTION 14.1(D)(II) as in effect at such time.
         Notwithstanding the foregoing, if the amount of Relevant NGC Tax paid
         to a taxing authority for a particular taxable period is less than
         $100,000, the Relevant NGC Tax shall be considered to be $0.00.

                  (d) The NGC Tax Loss Payment shall be made within thirty (30)
         days after the latest of (i) the settlement with the taxing authority
         of the claim for NGC Taxes, (ii) the expiration of the period for
         appeal of a final adjudication of the claim for NGC Taxes, (iii) the
         rendering of a determination by the Arbitrator of the amount of the NGC
         Tax Loss, or (iv) the expiration of the period for Surviving
         Corporation to give notice that it contests the amount of the NGC Tax
         Loss Payment requested by Chevron in an NGC Tax Loss Indemnity
         Statement. (The occurrence of an event described in SECTION 7.8(D)(I)
         OR (II) shall be referred to in this SECTION 7.8 as a "FINAL
         DETERMINATION"). If an NGC Tax Loss Payment is not made when due, then
         the amount thereof shall bear interest for the period of time that the
         amount remains unpaid at the lesser of (i) the highest lawful rate, or
         (ii) the rate of interest accruing under Section 6621(a)(2) of the
         Code. Any NGC Tax Loss Payment shall be increased by an amount of
         interest at Chevron's effective borrowing rate as in effect from
         time-to-time from the date on which Surviving Corporation makes the
         payment of the Relevant NGC Tax for which such NGC Tax Loss Payment is
         made, until the date the related NGC Tax Loss Payment is due.

                  (e) Surviving Corporation shall give prompt notice to Chevron
         of any Tax adjustment proposed in writing pursuant to any Tax Audit
         controlled by Surviving Corporation which adjustment could reasonably
         be expected to give rise to an NGC Tax Loss Payment under SECTION
         7.8(A) and prompt notice of the Final Determination of such Tax Audit
         (the "FINAL DETERMINATION NOTICE"). The Final Determination Notice
         shall set forth (i) in reasonable detail Surviving Corporation's good
         faith computation of the amount of any NGC Tax Loss Payment required
         under SECTION 7.8(A), (ii) the procedure (as described in SECTION
         7.8(F) below) Chevron must follow to respond, and (iii) a reference to
         SECTION 7.8 of this Agreement.

                  (f) Within one hundred twenty (120) days of the Final
         Determination Notice, Chevron shall notify Surviving Corporation in a
         written notice setting forth in reasonable detail Chevron's good faith
         computations of the amount of any NGC Tax Loss Payment required under
         SECTION 7.8(A), the basis of Chevron's request for such payment, and
         the procedure (as described in SECTION 7.8(G) below) by which Surviving
         Corporation may contest the amount (including the timing of the written
         notice of contest).


                                       49

                  (g) Within one hundred twenty (120) days of the receipt of the
         notice given in SECTION 7.8(F), Surviving Corporation may contest by
         written notice to Chevron the amount of the NGC Tax Loss Payment
         proposed by Chevron. After the notice in this SECTION 7.8(G) has been
         given, Chevron and Surviving Corporation, at their joint expense, shall
         select one (1) Arbitrator (as defined in SECTION 7.6(D)). If, within
         thirty (30) days after the notice in this SECTION 7.8(G) has been
         given, Chevron and Surviving Corporation cannot agree on one (1)
         jointly chosen Arbitrator, then each shall select one (1) Arbitrator at
         its own cost and expense. Such two (2) Arbitrators selected by Chevron
         and Surviving Corporation shall then select a third Arbitrator (other
         than themselves) to redetermine the amount of the NGC Tax Loss Payment
         so contested, which redetermination shall be binding and conclusive. If
         such third Arbitrator redetermines that the amount of the NGC Tax Loss
         Payment is less than the amount shown in the notice of Chevron so
         contested, the amount of the NGC Tax Loss Payment shall be such
         redetermined amount. If such Arbitrator determines that the amount of
         the NGC Tax Loss Payment was equal to or higher than the amount shown
         in the notice of Chevron, the payment in such notice shall be the NGC
         Tax Loss Payment.

                  (h) Notwithstanding any other provisions of this Agreement,
         all of Surviving Corporation's and Chevron's obligations under this
         Agreement relating to the making of NGC Tax Loss Payments or Refund
         Payments and any and all Tax Returns, audits, examinations, and
         proceedings relating thereto shall survive the Closing for a period
         ending ninety (90) days after the latest of (i) the lapse of the
         applicable period for assessment, imposition, or refund of Tax (as the
         same may be extended) with respect thereto, (ii) receipt of the notice
         described in SECTION 7.8(E) hereof or the Refund Payment Notice, (iii)
         the lapse of the applicable period for assessment, imposition or refund
         of Tax (as the same may be extended) relating to the taxable year or
         period in which any Tax savings are actually realized pursuant to
         SECTION 7.8(B) or SECTION 7.8(I), or (iv) the determination of the
         Arbitrator referred to in SECTION 7.8(G). This SECTION 7.8(H) shall not
         prejudice the survival of any warranty, representation or covenant
         under this Agreement.

                  (i) If the amount of the Gross Tax Loss decreases as the
         result of an increase in the present value of the reasonably expected
         Tax savings or refunds taken into account in the previous determination
         of the Gross Tax Loss as a result of the reasonable expectation of
         either an acceleration in achieving Tax Savings or refunds or the
         ability to achieve Tax Savings or refunds not previously expected, then
         Chevron shall pay to Surviving Corporation an amount equal to the
         product of the decrease in the Gross Tax Loss at such time and the
         fraction described in SECTION 14.1(D)(II) as in effect at such time,
         but in no event shall such payment (herein referred to as the "Refund
         Payment") be in excess of the amount of NGC Tax Loss Payments
         previously made to Chevron by Surviving Corporation. Any Refund Payment
         shall be increased by an amount of interest at Chevron's effective
         borrowing rate as in effect from time-to-time from the date on which
         the Refund Payment Notice is received by Chevron until the date the
         Refund Payment is due. Upon such a decrease in the Gross Tax Loss,
         Surviving Corporation shall give Chevron prompt notice of the decrease
         in the Gross Tax Loss and a request for a Refund Payment (the "Refund
         Payment Notice"). The Refund Payment Notice shall set forth (i) in
         reasonable detail Surviving Corporation's good faith computation of

                                       50

         the amount of the Refund Payment required under this paragraph, (ii)
         the procedure (as described below) Chevron must follow to respond, and
         (iii) a reference to SECTION 7.8 of this Agreement. Within one hundred
         twenty (120) days of the receipt of the Refund Payment Notice, Chevron
         may contest by written notice to Surviving Corporation the amount of
         the requested Refund Payment, in which event Chevron and Surviving
         Corporation shall follow the arbitration procedures set forth in
         SECTION 7.8(G). If the Arbitrator redetermines that the amount of the
         Refund Payment is less than the amount shown in the notice of Surviving
         Corporation so contested, the amount of the Refund Payment shall be
         such redetermined amount. If such Arbitrator determines that the amount
         of the Refund Payment was equal to or higher than the amount shown on
         the Refund Payment Notice, the payment requested in such notice shall
         be the Refund Payment. The Refund Payment shall be made within thirty
         (30) days after the latest of (i) the settlement with the taxing
         authority of the claim for NGC Taxes, (ii) the expiration of the period
         for appeal of a final adjudication of the claim for NGC Taxes, (iii)
         the rendering of a determination by the Arbitrator as to the amount of
         the relevant Refund Payment or (iv) the expiration of the period for
         Chevron to give notice that it contests the amount of a Refund Payment
         requested by Surviving Corporation in a Refund Payment Notice. If the
         Refund Payment is not paid when due, then it shall bear interest for
         the period that the amount remains unpaid at the rate described in the
         penultimate sentence of SECTION 7.8(D).

                  (j) Notwithstanding any other provisions of this Agreement,
         the provisions of this SECTION 7.8 shall apply exclusively to issues
         regarding NGC Tax Loss Payments pursuant to SECTION 7.8(A) or Refund
         Payments pursuant to SECTION 7.8(I).


                                    ARTICLE 8

                         EMPLOYEES AND BENEFITS MATTERS

         8.1      REPRESENTATIONS AND WARRANTIES OF NGC.

                  (a) EMPLOYEE BENEFIT PLANS. SCHEDULE 8.1(A) to this Agreement
         includes a correct and complete list of all pension and welfare plans
         as defined in Sections 3(1) and 3(2) of ERISA and all other employee
         benefit agreements or arrangements, including but not limited to
         deferred compensation plans, incentive plans, bonus plans or
         arrangements, savings plans, stock option plans, stock purchase plans,
         golden parachute agreements, severance pay plans, cafeteria plans,
         employee assistance programs, employment contracts and other similar
         plans, agreements and arrangements that are currently in effect, or
         have been approved before the date of this Agreement but are not yet
         effective, for the benefit of directors, officers, employees or former
         employees (or their beneficiaries) of NGC or any of its Subsidiaries.
         NGC has delivered or made available to Chevron, as to each plan,
         agreement or arrangement, as applicable, a true and correct copy of (i)
         the plan, agreement or arrangement, (ii) the trust, group annuity
         contract or other document that provides the funding for the plan,
         agreement or arrangement, if any, (iii) the three most recent annual
         Form 990 and 1041 reports, if any, (iv) the Form 5500 returns that have
         been prepared and filed for each fiscal year of the plan beginning in
         or

                                       51

         after 1991, if any, (v) the most recent actuarial report or valuation
         statement, if any, (vi) the most current summary plan description,
         booklet, or other descriptive written materials, if any, and each
         summary of material modifications prepared after the last summary plan
         description, (vii) the most recent IRS determination letter, if any,
         and all rulings or determinations requested from the IRS after the date
         of any exemption letter, if any, and (viii) all other correspondence
         from the IRS or the Department of Labor that relates to one or more of
         the plans, agreements or arrangements which could reasonably be
         expected to result in the disqualification of a plan for tax purposes
         under Section 401(a) of the Code or a liability which would have a
         Material Adverse Effect on NGC.

                  (b) Except as set forth on SCHEDULE 8.1(B), every employee
         welfare benefit plan and every employee pension benefit plan as defined
         in Sections 3(1) and 3(2) of ERISA listed on SCHEDULE 8.1(A) (i) is in
         substantial compliance with all material requirements of Parts 1 and 6
         of Subtitle B of Title I of ERISA; (ii) has had the appropriate Form
         5500 filed, timely, for each year of its existence, if required; (iii)
         has not engaged in any prohibited transaction described in Sections 406
         or 407 of ERISA or Section 4975 of the Code unless it was exempt under
         Section 408 of ERISA or Section 4975 of the Code, as applicable; (iv)
         has at all times complied with the bonding requirements of Section 412
         of ERISA; (v) has no issue pending (other than the payment of benefits
         in the normal course) nor any issue resolved adversely to NGC or any of
         its Subsidiaries that may subject NGC or any of its Subsidiaries in the
         future to the payment of a penalty, interest or tax and (vi) can be
         unilaterally terminated or amended on no more than 90 days' notice;
         except, in each such case, where it would not, either individually or
         in the aggregate, reasonably be expected to have a Material Adverse
         Effect on NGC. All voluntary employee benefit associations maintained
         or contributed to by NGC or any of its Subsidiaries have been submitted
         to and approved by the IRS as exempt from federal income tax under
         Section 501(c)(9) of the Code. Except as set forth in SCHEDULE 8.1(B),
         neither NGC nor any of its Subsidiaries provides employee
         post-retirement medical or health coverage or contributes to or
         maintains any employee welfare benefit plan that provides for health
         benefit coverage following termination of employment except as is
         required by Part 6 of Subtitle B of Title I of ERISA or Section 4980B
         of the Code. Except as set forth on SCHEDULE 8.1(B), all employee
         pension benefit plans as defined in Section 3(2) of ERISA listed on
         SCHEDULE 8.1(A) which are intended to qualify under Section 401(a) of
         the Code have been submitted to and approved as qualifying under
         Section 401(a) of the Code by the IRS or the applicable remedial
         amendment period will not have ended prior to the Closing Date; and to
         the knowledge of NGC, no facts have occurred that if known by the IRS
         could cause disqualification of those plans. All employee pension
         benefit plans listed on SCHEDULE 8.1(A) to which Section 412 of the
         Code is applicable have fully complied with the funding requirements of
         that Section and there is no accumulated funding deficiency as defined
         in Section 302(a)(2) of ERISA (whether or not waived) in any one or
         more of those plans. All premiums (and any interest, charges and
         penalties for late payment of premiums) due the PBGC with respect to
         each employee pension benefit plan listed on SCHEDULE 8.1(A) for which
         premiums are required have been paid when due. No employee pension
         benefit plan, whether or not listed on SCHEDULE 8.1(A), has been, or is
         reasonably expected to be, terminated under circumstances that could
         result in a liability by NGC or any of its Subsidiaries to the PBGC
         that would reasonably be expected to have a Material Adverse

                                       52

         Effect on NGC. There have been no "reportable events" (as defined in
         Section 4043(b) of ERISA and the regulations under that Section) with
         respect to any employee pension benefit plan subject to Title IV of
         ERISA listed on SCHEDULE 8.1(A). Except as set forth on SCHEDULE
         8.1(B), neither NGC nor any of its Subsidiaries (i) has ceased
         operations at a facility so as to become subject to the provisions of
         Section 4062(e) of ERISA, withdrawn as a substantial employer so as to
         become subject to the provisions of Section 4063 of ERISA or ceased
         making contributions on or before the Closing Date to any employee
         pension benefit plan subject to ERISA to which either NGC or any of its
         Subsidiaries made contributions at any time during the six years before
         the Closing Date or (ii) has made a complete or partial withdrawal from
         a multiemployer plan (as defined in Section 3(37) of ERISA) so as to
         incur withdrawal liability as defined in Section 4201 of ERISA. Either
         the applicable plan document or SCHEDULE 8.1(B) contains a complete and
         accurate statement of all actuarial assumptions applied to determine
         the present value of accrued benefits under all employee benefit plans
         subject to actuarial assumptions. All amounts owed under the deferred
         compensation arrangements described in SCHEDULE 8.1(A) are included as
         liabilities in the financial statements included in the NGC SEC
         Documents. Neither NGC nor any of its Subsidiaries has incurred a
         liability for any excise tax (whether or not yet assessed by the IRS)
         under Section 4971, 4972, 4975, 4976, 4978B, 4979, 4979A or 4980B of
         the Code that would reasonably be expected to have a Material Adverse
         Effect on NGC.

                  (c) LABOR MATTERS. Except as set forth on SCHEDULE 8.1(C), (i)
         there are no agreements existing between any member of the NGC Group
         and any labor union or association representing any employees of the
         NGC Group; (ii) there is no material work stoppage against the NGC
         Group with respect to its business or operations pending or, to the
         knowledge of NGC, threatened and (iii) there is no material labor
         dispute, arbitration, lawsuit or administrative proceeding threatened
         relating to labor matters with respect to the business or operations of
         NGC or affect the ability of the Surviving Corporation to perform its
         obligations under the Ancillary Agreements.

         8.2      REPRESENTATIONS AND WARRANTIES OF CHEVRON.

                  (a) EMPLOYEES AND EMPLOYEE BENEFIT PLANS. Prior to the Closing
         Date, Chevron will provide any notification or notice required to be
         given to any employee of a member of the Chevron Group pursuant to the
         provisions of the Worker Adjustment and Retraining Notification Act
         (the "WARN ACT") in connection with or arising out of the contribution
         of the Contributed Businesses and the Contributed West Texas LPG
         Pipeline Business to Newco. With respect to any "employee benefit plan"
         within the meaning of Section 3(3) of ERISA, which is sponsored,
         maintained or contributed to, or has been sponsored, maintained or
         contributed to within six years prior to the Closing Date, by Chevron
         or any corporation, trade, business or entity under common control with
         Chevron, within the meaning of Section 414(b), (c) or (m) of the Code
         or Section 4001 of the ERISA ("COMMONLY CONTROLLED ENTITY"), (1) no
         withdrawal liability, within the meaning of Section 4201 of ERISA, has
         been incurred, which withdrawal liability has not been satisfied and
         could give rise to a Lien on any of the assets or properties that
         comprise the Contributed Businesses or the Contributed West Texas LPG
         Pipeline Business, (2) no liability to the PBGC has been incurred by
         Chevron or any Commonly

                                       53

         Controlled Entity, which liability has not been satisfied and could
         give rise to a Lien on the Contributed Businesses, (3) no accumulated
         funding deficiency, whether or not waived, within the meaning of
         Section 302 of ERISA or Section 412 of the Code has been incurred and
         (4) all contributions (including installments) to such plan required by
         Section 302 of the ERISA and Section 412 of the Code have been timely
         made. As of the Closing Date, the Affected Employees will have a fully
         vested interest in their accrued benefits under all plans maintained by
         the Chevron Group that are intended to be qualified under Section
         401(a) of the Code and in which Prospective Employees participate.

                  (b) LABOR MATTERS. There are no agreements existing between
         any member of the Chevron Group and any labor union or association
         representing any of the employees of the Warren Petroleum Company, the
         employees of the NGBU or any other employee of the Chevron Group who
         operates, is employed in connection with, or otherwise supports the
         Contributed Businesses or the Contributed West Texas LPG Pipeline
         Business. There is no material work stoppage against the Chevron Group
         with respect to the business or operations of the Contributed
         Businesses or the Contributed West Texas LPG Pipeline Business pending
         or, to the knowledge of Chevron, threatened. There is no material labor
         dispute, arbitration, lawsuit or administrative proceeding threatened
         relating to labor matters with respect to the business or operations of
         the Contributed Businesses or the Contributed West Texas LPG Pipeline
         Business.

         8.3 CONDUCT OF NGC PRIOR TO CLOSING RELATING TO EMPLOYEE BENEFIT PLANS.
During the period from the date of this Agreement through the earlier to occur
of the Effective Time or the Termination Date, except in the ordinary course
consistent with prior practices or as disclosed in NGC's proxy statement
relating to its 1996 annual meeting, NGC shall not, and shall not permit any
Subsidiary of NGC to, adopt or amend (other than amendments that reduce the
amounts payable by NGC or its Subsidiaries or amendments required by law to
preserve the qualified status of a plan or a contract) any collective bargaining
agreement or employee benefit plan or enter into any employment or severance
arrangement with any Person (including, without limitation, contracts with
management of NGC or its Subsidiaries that might require that payments be made
upon the consummation of the transactions contemplated hereby) or amend any
existing contracts to increase any amounts payable thereunder or benefits
provided thereunder. Neither NGC nor any of its Subsidiaries nor any plan listed
on SCHEDULE 8.1(A) will (a) engage in any nonexempt "prohibited transaction" (as
defined in Section 406 of ERISA and Section 4975(c) of the Code) that would
reasonably be expected to have a Material Adverse Effect on NGC, (b) incur any
"accumulated funding deficiency" (as defined in Section 302 of ERISA) whether or
not waived, (c) terminate any plan in a manner that could result in the
imposition of a lien on any property of NGC or any of its Subsidiaries pursuant
to Section 4068 of ERISA or (d) take any action that (1) could adversely affect
the qualification under the Code of any plan or its compliance with the
applicable requirements of ERISA or that might result in any "reportable event"
(as defined in Section 4043(b) of ERISA) and (2) would reasonably be expected to
have a Material Adverse Effect on NGC.


                                       54

         8.4      OFFERS OF EMPLOYMENT.

                  (a) The NGC Group and the Chevron Group shall jointly select
         the Prospective Employees who shall receive offers of employment with
         the Surviving Corporation and its Subsidiaries (the "NEWCO GROUP") and
         the employees of the NGC Group who shall remain employed by the Newco
         Group. The term "PROSPECTIVE EMPLOYEES" shall mean the employees of the
         Chevron Group who operate, are employed in connection with, or
         otherwise are associated with the Contributed Businesses.

                  (b) The NGC Group shall make offers of employment with the
         Newco Group contingent and effective upon Closing to those employees of
         the Chevron Group that are selected from among the Prospective
         Employees. Such employment offers shall be on terms and conditions to
         be determined by the NGC Group, but not inconsistent with the
         provisions of this ARTICLE 8. The NGC Group's offers of employment to
         the selected Prospective Employees shall be made in writing.

                  Those employees of the Chevron Group who accept the NGC
         Group's employment offers and become employees actively at work with
         the Newco Group as of Closing (or at any time within 30 days thereafter
         or, if later, the day after the last day of a Family and Medical Leave
         Act leave that started on or before the Closing) are the "AFFECTED
         EMPLOYEES," and the first date an Affected Employee is actively at work
         with the Newco Group on or after Closing is that Affected Employee's
         "EMPLOYMENT DATE." The employees who operate, are employed in
         connection with, or otherwise are associated with the Contributed
         Businesses and who do not become Affected Employees are the "REMAINING
         EMPLOYEES."

                  Nothing in this Agreement shall affect the Newco Group's right
         to change the terms and conditions of employment or terminate the
         employment of any Affected Employee on or after his or her Employment
         Date, with or without cause, provided that the Newco Group shall comply
         with (i) the terms of SECTION 8.7(A) below and (ii) the service
         recognition provisions of this ARTICLE 8.

                  Any Prospective Employee selected by the NGC Group who was not
         actively at work at Closing shall continue to be the responsibility of
         the Chevron Group after such date and shall not become an employee of
         the Newco Group until such Employee's Employment Date. The Newco Group
         shall have no obligation under this Agreement to employ any Prospective
         Employee who has accepted its employment offer but is not actively at
         work with the Newco Group at Closing or within the later of 30 days
         after Closing or the day after the last day of a Family and Medical
         Leave Act leave that started on or before the Closing.

                  (c) Chevron shall pay the relocation costs incurred in
         connection with the first relocation by any Affected Employee who is
         required to relocate as a condition to his or her employment offer with
         the Newco Group made pursuant to paragraph (b) of this SECTION 8.4.


                                       55

         8.5      DEFINED BENEFIT PENSION PLANS.

                  The Chevron Corporation Retirement Plan and related excess
         benefit plan (the "CHEVRON PENSION PLAN") shall retain the liability
         for the Affected Employees' pension benefits accrued before their
         Employment Dates, shall fully vest as of the Closing Date the Affected
         Employees who are participants in the Chevron Pension Plan, and shall
         permit distributions to any Affected Employee who is eligible to elect
         an immediate distribution as of his or her Employment Date based upon
         his or her service and accrued benefit as of such Employment Date.
         Chevron shall cause the Chevron Pension Plan to recognize the Affected
         Employees' service with the Newco Group on and after their Employment
         Dates and before a distribution is received from the Chevron Pension
         Plan for purposes of determining eligibility to receive a benefit
         (including, without limitation, eligibility to receive subsidized early
         retirement benefits, Social Security supplements and ancillary
         benefits), but not for the purpose of accruing additional benefits.

         8.6      QUALIFIED DEFINED CONTRIBUTION PLANS.

                  (a) The Chevron Corporation Profit Sharing/Savings Plan shall
         fully vest as of the Closing Date the account balances of the Affected
         Employees who are participants in such plan, and Chevron shall take
         such actions, if any, as may be necessary to provide for the
         distribution to or on behalf of the Affected Employees of their vested
         account balances. To the extent permitted by applicable law, Affected
         Employees with loans outstanding under the Profit Sharing/Savings Plan
         as of the Closing may directly rollover any such loan to the NGC Profit
         Sharing/401(k) Savings Plan provided the loan has not been accelerated
         at the time of the rollover. Chevron shall use its best efforts to (i)
         permit each prospective Affected Employee to elect prior to the Closing
         Date (with such election to be contingent upon the Closing and such
         individual actually becoming an Affected Employee) a direct rollover of
         his or her rolloverable Chevron Corporation Profit Sharing/Savings Plan
         account balance to the NGC Profit Sharing/401(k) Savings Plan and (ii)
         cause the Chevron Corporation Profit Sharing/Savings Plan to deliver to
         the NGC Profit Sharing/401(k) Savings Plan on the Closing Date (or as
         soon thereafter as reasonably practicable) the promissory notes and
         other loan documentation, if any, of the Affected Employees who have
         elected such a direct rollover in accordance with the procedures
         prescribed by Chevron.

                  (b) The NGC Profit Sharing/401(k) Savings Plan shall accept
         the direct rollover as provided in Code section 401(a)(31) of electing
         Affected Employees' benefits in cash and, if applicable, promissory
         notes that are not accelerated from the Chevron Corporation Profit
         Sharing/Savings Plan and the Chevron Corporation Retirement Plan.

         8.7      SEVERANCE PLANS.

                  (a) If, within twelve months after his or her Employment Date,
         any of the Affected Employees is terminated by the Newco Group for
         reasons other than cause, or is required to transfer to a job location
         that is more than fifty (50) miles from his or her current job location
         (other than a transfer that was a condition of the original employment
         offer with the Newco Group) or to take a reduction in base rate of pay,
         but refuses such

                                       56

         transfer or reduction and terminates his or her employment with the
         Newco Group within 10 days of notice of such transfer or reduction,
         then the Newco Group shall (i) pay the Affected Employee one-half of a
         month of his or her base rate of pay for each completed or partial year
         of service with the Chevron Group and the Newco Group, subject to a
         minimum of two (2) months and a maximum of 12 months of such pay; and
         (ii) provide for the continuation of the Newco Group's active employee
         medical coverage for three months after termination of employment with
         the same employee contribution amounts that apply to the Newco Group's
         similarly situated active employees. Service used for this purpose
         shall be the service recognized by the Newco Group pursuant to SECTION
         8.12 below.

                  (b) NGC and the Newco Group shall pay and be responsible for
         any and all severance costs and expenses incurred by NGC or the Newco
         Group and the Chevron Group shall pay and be responsible for any and
         all severance costs and expenses incurred by any member of the Chevron
         Group with respect to any of the Prospective Employees (including the
         relocation costs described in SECTION 8.4(C)). If the aggregate amount
         of severance costs and expenses paid and to be paid by NGC and the
         Newco Group as a result of actions taken to give effect to the
         transactions contemplated by this Agreement (excluding the amount paid
         and to be paid pursuant to SECTION 8.7(A)), with respect to
         terminations that occur during the period beginning on January 21,
         1996, and ending on the date that is 90 calendar days after the
         Effective Time is less than $8,400,000, then, within 30 calendar days
         after the end of such period, the Surviving Corporation shall pay an
         amount to Chevron equal to the sum of $8,400,000, less such severance
         costs and expenses; provided, however, that the amount of such payment
         shall not exceed the aggregate amount of severance costs and expenses
         paid and to be paid during such period by the Chevron Group with
         respect to the Prospective Employees who are terminated by the Chevron
         Group during such period.

         8.8 VACATION PAY. Due to differences between Newco's vacation policies
relating to salaried employees and hourly employees, Chevron and NGC agree that
the parties shall take the following actions relating to accrued and unused
vacation time of the Affected Employees. As of the Closing, Chevron shall pay
all Affected Employees who are classified as salaried employees under Newco's
system of classification for their unused and accrued vacation. The Newco Group
shall give all such Affected Employees the right to take a vacation before
December 31, 1996, representing a pro rata amount of vacation earned under the
Newco Group vacation policy, and calculated by dividing the number of full
calendar months remaining in 1996 after the Closing by twelve and multiplying
the result by the number of weeks of vacation to which the Affected Employee
normally would be entitled under the Newco Group's vacation policy. With respect
to Affected Employees who are classified as hourly employees under Newco's
system of classification, the Newco Group shall assume responsibility for such
Affected Employees' accrued vacation as of their respective Employment Dates,
and such Affected Employees' vacation entitlements based on their respective
service after such Employment Dates shall be determined with reference to
Newco's vacation policy.

         8.9 MEDICAL AND DENTAL PLANS. Each Affected Employee shall be eligible
to enroll in a medical and dental plan of the Newco Group as of his or her
Employment Date. If such Affected Employee was enrolled in the corresponding
plan of the Chevron Group immediately

                                       57

before his or her Employment Date, the Surviving Corporation shall cause the
Newco Group's medical and dental plans to waive any preexisting condition
limitations and to recognize each such Affected Employee's expenditures under
the corresponding Chevron medical, mental health, substance abuse and dental
plans (and those of his or her dependents who were covered under such plans) for
the calendar year in which the Employment Date occurs toward any applicable
deductible and annual out-of-pocket limit for such calendar year.

         8.10     POST-RETIREMENT WELFARE BENEFITS.

                  The Chevron Group shall be responsible for all post-retirement
medical, dental, life insurance coverage and all other benefits for the
Remaining Employees. The Chevron Group also shall make available its
post-retirement medical, dental and life insurance benefit coverage to any
Affected Employee who as of his or her Employment Date is eligible to receive
and enroll in such Chevron post-retirement welfare benefit coverage (the
"ELIGIBLE AFFECTED EMPLOYEES"). The Eligible Affected Employees shall be treated
in the same manner as other similarly situated employees of the Chevron Group
who retired as of the applicable Employment Date (and shall be subject to the
rights of the Chevron Group to amend or terminate such coverage with respect to
such employees).

         8.11     THE NEWCO GROUP'S LIFE INSURANCE COVERAGE.

                  NGC agrees that as of an Affected Employee's Employment Date,
the Affected Employee may elect the Newco Group's supplemental life insurance
coverage on his or her life and dependent life insurance coverage without
evidence of insurability; provided, however, that supplemental life insurance
coverage with respect to an Affected Employee's spouse shall be made available
without evidence of insurability up to a maximum amount equal to the greater of
(a) $50,000 or (b) the level of insurance coverage in effect with respect to
such spouse under the corresponding plan of the Chevron Group immediately prior
to such Employment Date.

         8.12 THE NEWCO GROUP'S OTHER EMPLOYEE BENEFITS; SERVICE RECOGNITION.

                  Except as otherwise specifically provided in this ARTICLE 8,
NGC agrees that as of their respective Employment Dates, the Affected Employees
will be eligible to participate in the employee benefit plans and programs of
the Newco Group that are maintained as of the Closing Date and are generally
applicable to employees of the Newco Group, and each Affected Employee's years
of service for eligibility and vesting (but not benefit accrual) purposes
recognized under the benefit plans and programs maintained by the Chevron Group
for the period preceding such Affected Employee's Employment Date shall be
recognized for such purposes under any comparable benefit plan or program
maintained by the Newco Group as of the Closing Date. If any employee benefit
plan or program established by the Newco Group after the Closing Date will
recognize service with the NGC Group for eligibility, vesting, benefit
eligibility or benefit accrual purposes, then such plan or program shall
likewise recognize for such purpose(s) the service with the Chevron Group for
each similarly situated Affected Employee.

                  (c) At Closing, Chevron will provide to the Surviving
         Corporation a list of all Affected Employees' service in a form that
         shall be sufficient to permit the Newco Group to fulfill its
         obligations under SECTION 8.12.

                  (d) If any of the arrangements described in this ARTICLE 8 are
         determined by the IRS or other applicable governmental authority, or by

         the Surviving Corporation shall modify such arrangements to as closely
         as possible retain the intent and economic benefits and burdens of the
         parties as reflected herein in a manner which is not prohibited by law.

                  (e) In the event that the Newco Group knowingly hires any
         Remaining Employee within six months after Closing, the Newco Group
         will notify Chevron of such event as soon as possible after the hire
         date.

         8.14 WARN ACT COMPLIANCE. Chevron shall provide to NGC and the
Surviving Corporation such information relating to any terminations by the
Chevron Group of employees made in respect of the Contributed Businesses or the
Contributed West Texas LPG Pipeline Business (other than Affected Employees) as
is necessary for the Surviving Corporation to comply with the provisions of the
WARN Act.

         8.15 SURVIVAL. Notwithstanding any other provisions of this Agreement,

complaint under applicable state or federal law, and all covenants and
agreements set forth in this ARTICLE 8 shall survive the Closing indefinitely.
This SECTION 8.15 shall not prejudice the survival of any other warranty,

         Surviving Corporation and its Subsidiaries or for the Surviving
         Corporation and its Significant Subsidiaries to own their respective
         assets and to operate their respective businesses, including, without
         limitation, the Contributed Businesses.

                  (f) The NGC Stockholder Approval shall have been obtained.

         12.2 CONDITIONS TO THE OBLIGATIONS OF CHEVRON REGARDING THE
COMBINATION. The obligation of Chevron to effect the Combination shall be
subject to the prior satisfaction of the following conditions (each of which may
be waived by Chevron in its sole discretion):

                  (a) The representations and warranties of NGC contained in
         this Agreement shall have been true and correct on the date of this
         Agreement and at and on the Closing Date as though such representations
         and warranties were made at and on such date, other than such breaches
         of such representations and warranties which in the aggregate would not
         reasonably be expected to have a Material Adverse Effect on NGC in an
         aggregate amount exceeding $25 million (including, without duplication,
         the effect of any Casualty Loss suffered by NGC); provided, however,
         that in evaluating whether there has been a breach of any
         representation or warranty for the purposes of this SECTION 12.2(A),
         any provision of the applicable representation or warranty limiting it
         to matters within the "knowledge" or "best knowledge" of a party or
         having a Material Adverse Effect or otherwise containing a limitation
         or exception relating to materiality shall be disregarded

                                       66

         and shall not be taken into account in determining the existence or
         magnitude of such a breach.

                  (b) NGC shall have performed and complied in all material
         respects with all agreements, obligations and conditions required by
         this Agreement to be performed or complied with by it on or prior to
         the Closing Date.

                  (c) Chevron shall have received an opinion of Akin, Gump,
         Strauss, Hauer & Feld, L.L.P., counsel for NGC, in substantially the
         form of EXHIBIT 12.2(C).

                  (d) Chevron shall have received tax representations in
         substantially the form attached hereto as EXHIBIT 12.2(D) from British
         Gas, NOVA and C. L. Watson and Steve Bergstrom so that, upon
         consummation of the Combination, not less than 80% of the aggregate
         issued and outstanding shares of Surviving Corporation Common Stock are
         covered by such tax representations (assuming that all of Chevron's
         shares of Surviving Corporation Common Stock are covered by such tax
         representation).

                  (e) Each Ancillary Agreement to which NGC or any of its
         Subsidiaries or Affiliates is a party shall have been executed and
         delivered by NGC and such Subsidiaries and Affiliates (as applicable).

         12.3 CONDITIONS TO THE OBLIGATIONS OF NGC REGARDING THE COMBINATION.
The obligations of NGC to effect the Combination shall be subject to the prior
satisfaction of the following conditions (each of which may be waived by NGC in
its sole discretion):

                  (a) The representations and warranties of Chevron contained in
         this Agreement shall have been true and correct on the date of this
         Agreement and at and on the Closing Date as though such representations
         and warranties were made at and on such date, other than such breaches
         of such representations and warranties which in the aggregate would not
         reasonably be expected to have a Material Adverse Effect on or with
         respect to the Contributed Businesses and the Contributed West Texas
         LPG Pipeline Business, taken as a whole, in an aggregate amount
         exceeding $25 million (including, without duplication, the effect of
         any Casualty Loss suffered by Chevron and the fair value of any
         Retained Assets, as described in SECTION 2.4); provided, however, that
         in evaluating whether there has been a breach of any representation or
         warranty for the purposes of this SECTION 12.3(A), any provision of the
         applicable representation or warranty limiting it to matters within the
         "knowledge" or "best knowledge" of a party having a Material Adverse
         Effect or otherwise containing a limitation or exception relating to
         materiality shall be disregarded and shall not be taken into account in
         determining the existence or magnitude of such a breach.

                  (b) Chevron shall have performed and complied in all material
         respects with all agreements, obligations and conditions required by
         this Agreement to be performed or complied with by it on or prior to
         the Closing Date.

                  (c) NGC shall have received an opinion of Pillsbury Madison &
         Sutro LLP, counsel for Chevron, in substantially the form of EXHIBIT
         12.3(C).

                                                        67

                  (d) Chevron and Newco shall have each executed and delivered
         the Contribution and Assumption Agreement.

                  (e) Chevron shall have received all of the material consents
         from third parties listed on SCHEDULE 12.3(E) hereto, in form and
         substance reasonably satisfactory to NGC, prior to or on the Closing
         Date.

                  (f) Chevron shall have caused each officer of Newco to resign
         effective as of the Effective Time, unless any such officer is named in
         SCHEDULE 2.2(E), in which case such officer shall remain as an officer
         of the Surviving Corporation and shall serve until his successor is
         duly elected and qualified.

                  (g) NGC shall have received tax representations in
         substantially the form attached hereto as EXHIBIT 12.3(G)(I) from
         Chevron, and shall have received the Code Section 1445 Affidavit
         attached hereto as EXHIBIT 12.3(G)(II) from Chevron.

                  (h) Each Ancillary Agreement to which Chevron or any of its
         Subsidiaries or Affiliates is a party shall have been executed and
         delivered by Chevron and such Subsidiaries and Affiliates (as
         applicable).


                                   ARTICLE 13

                                   TERMINATION

         13.1 TERMINATION. This Agreement may be terminated, with the effect set
forth in SECTION 13.3, at any time before the Effective Time:

                  (a) by written consent of Chevron and NGC, which termination
         shall be approved by the board of directors of NGC and Chevron,
         respectively;

                  (b) by either NGC or Chevron, if the Effective Time shall not
         have occurred by 5:00 P.M., Houston, Texas time, on September 30, 1996,
         PROVIDED, HOWEVER, that the right to terminate this Agreement under
         this SECTION 13.1(B) shall not be available to any party whose failure
         to fulfill any covenant under SECTION 9.3 under this Agreement has been
         the cause of or resulted in the failure of the Combination to occur on
         or before such date;

                  (c) by either NGC or Chevron, if a Governmental Entity shall
         have issued an order, decree, or ruling or taken any other action, in
         each case having the effect of permanently restraining, enjoining or
         otherwise prohibiting the Combination;

                  (d) by NGC, upon a breach of any representation, warranty or
         covenant (other than SECTION 10.3) on the part of Chevron set forth in
         this Agreement, or if any representation or warranty of Chevron shall
         have become untrue, in either case, such that the conditions set forth
         in SECTIONS 12.1 OR 12.3 would not be satisfied (a "TERMINATING CHEVRON
         BREACH"), provided, that if such Terminating Chevron Breach is cured by

                                       68

         Chevron within 30 calendar days after notice thereof through the
         continuous exercise of its reasonable best efforts, then NGC may not
         terminate this Agreement under this SECTION 13.1(D);

                  (e) by Chevron, upon a breach of any representation, warranty
         or covenant (other than SECTION 11.8) on the part of NGC set forth in
         this Agreement, or if any representation or warranty of NGC shall have
         become untrue, in either case, such that the conditions set forth in
         SECTIONS 12.1 OR 12.2 would not be satisfied (a "TERMINATING NGC
         BREACH"), provided, that if such Terminating NGC Breach is cured by NGC
         within 30 calendar days after notice thereof through the continuous
         exercise of its reasonable best efforts, then Chevron may not terminate
         this Agreement under this SECTION 13.1(E);

                  (f)      by NGC, if Chevron is in breach of SECTION 10.3; or

                  (g)      by Chevron, if NGC is in breach of SECTION 11.8.

Termination of this Agreement pursuant to this SECTION 13.1 shall be effected by
written notice by the party terminating the Agreement to the other party setting
forth the basis for such termination. The date such notice is received shall be
deemed the "TERMINATION DATE."

         13.2     TERMINATION DUE TO TITLE MATTERS.

                  (a) During the period prior to and including June 15, 1996,
         each party may, to the extent it deems appropriate, conduct, at its
         sole cost, such additional title examination or investigation as it may
         choose to conduct with respect to the Facilities of the other party to
         determine if the representations set forth in SECTIONS 4.16 and 5.18
         (as applicable) are true and correct. Each party shall confine its
         title examination and investigation of the other party's Facilities to
         public records, the files and records of the other party and abstracts
         and other title information in the possession of or prepared by third
         parties in the business of investigating or examining title. In
         connection with such examination and investigation, each of NGC and
         Chevron shall make available to the other party all title opinions,
         supplemental title opinions and other title information in their
         possession relating to the NGC Facilities and the Chevron Facilities
         (the "FACILITIES"), as applicable. During the course of each party's
         investigation, each party shall confer with the other party concerning
         any Defects or potential Defects identified during such investigation.
         At the close of business on June 15, 1996, each party shall cease its
         title investigation and examination and shall prepare a schedule (a
         "DEFECT SCHEDULE") setting forth in reasonable detail each Defect in
         title to the other party's Facilities that were identified as a result
         of the first party's examination or otherwise. A party's Defect
         Schedule shall be delivered to the other party by no later than the
         close of business on June 21, 1996. In the event that a party does not
         provide a Defect Schedule to the other party on or before June 21,
         1996, then such party has no right to terminate this Agreement pursuant
         to paragraph (b) below and such party shall be precluded from counting
         any Defect detected, discovered or otherwise brought to such party's
         attention towards the $25 million Material Adverse Effect threshold set
         forth in SECTION 12.2(A) and SECTION 12.3(A), as applicable; provided,
         however, that the failure

                                       69

         to so provide a Defect Schedule shall in no way prejudice any rights
         that either party might have under ARTICLE 14 after the Closing Date.

                  (b) If either party reasonably believes that the defects
         identified in its Defect Schedule would cause a diminution in the value
         of the other party's Facilities of $10 million or more (in the
         aggregate), then the first party shall set forth in its Defect Schedule
         such party's best estimate of the diminution in value in the applicable
         Facility caused by each Defect and the aggregate diminution in value of
         the applicable Facilities caused by all of the Defects listed in the
         schedule. After receipt of the Defect Schedule, the parties shall
         confer and may mutually agree for the second party to take such actions
         as the first party deems reasonably necessary to cure any such Defects,
         including, in the case of Chevron, retaining such asset and its value
         as a Retained Asset pursuant to SECTION 2.4 hereof. In the event the
         parties are unable to so agree, then the first party may terminate this
         Agreement without liability to either party.

                  (c) If a party provides the other party with a Defect Schedule
         but does not believe that the Defects listed thereon would cause a
         diminution in the value of the other party's Facilities of $10 million
         or more (in the aggregate), then the first party shall not be entitled
         to terminate this Agreement as a result of such Defects but shall be
         entitled to (i) count any Defect listed on such schedule, along with
         other losses for breaches of representations, warranties, covenants and
         agreements, towards the $25 million Material Adverse Effect threshold
         set forth in SECTION 12.2(A) and SECTION 12.3(A) and (ii) assert a
         claim for indemnification relating to each such Defect pursuant to
         ARTICLE 14, but only to the extent that such Defect results in a Loss
         pursuant to SECTION 14.1(C).

                  (d) Each party's rights under this Section shall be in
         addition to, and not in limitation of, any rights of access or
         inspection which such party may otherwise have under this Agreement.

         13.3     EFFECT OF TERMINATION.

                  (a) If this Agreement is terminated by either Chevron or NGC
         as provided in SECTION 13.1(A), 13.1(B), 13.1(C), or 13.2 of this
         Agreement, then this Agreement shall become void and there shall be no
         liability or obligation with respect to the terminated provisions of
         this Agreement on the part of Chevron or NGC, or their respective
         officers or directors; provided, however, that in the event that this
         Agreement is terminated pursuant to SECTION 13.1(B), then the terms of
         SECTION 13.3(D) shall survive the termination of this Agreement in
         accordance with its terms.

                  (b) If this Agreement is terminated by NGC pursuant to SECTION
         13.1(F), then Chevron shall pay to NGC, on the first Business Day
         following such termination, the amount of $30 million by wire transfer
         of immediately available funds to an account designated by NGC, as
         liquidated damages, but not as a penalty. NGC agrees that said cash
         payment shall be its sole and total damages and relief hereunder in the
         event of such a breach. The parties to this Agreement acknowledge and
         agree that NGC's actual damages, in the event of a termination pursuant
         to SECTION 13.1(F), would be difficult to ascertain because of the
         uncertainties of estimating the value of NGC's expenses and

                                       70


         management time in pursuing the Combination and its lost opportunity
         costs. Because of this uncertainty and the differences of opinion with
         relating thereto, NGC agrees that such amount is reasonable as
         liquidated damages; provided, however, that in no event shall Chevron
         be obligated to pay NGC $30 million in liquidated damages under this
         SECTION 13.3(B) if NGC, at the time it terminated this Agreement, could
         not satisfy the conditions set forth in SECTIONS 12.2(A) and 12.2(B).

                  (c) If this Agreement is terminated by Chevron pursuant to
         SECTION 13.1(G), then NGC shall pay to Chevron, on the first Business
         Day following such termination, the amount of $30 million by wire
         transfer of immediately available funds to an account designated by
         Chevron, as liquidated damages, but not as a penalty. Chevron agrees
         that said cash payment shall be its sole and total damages and relief
         hereunder in the event of such a breach. The parties to this Agreement
         acknowledge and agree that Chevron's actual damages, in the event of a
         termination pursuant to SECTION 13.1(G), would be difficult to
         ascertain because of the uncertainties of estimating the value of
         Chevron's expenses and management time in pursuing the Combination and
         its lost opportunity costs. Because of this uncertainty and the
         differences of opinion with relating thereto, Chevron agrees that such
         amount is reasonable as liquidated damages; provided, however, that in
         no event shall NGC be obligated to pay Chevron $30 million in
         liquidated damages under this SECTION 13.3(C) if Chevron, at the time
         it terminated this Agreement, could not satisfy the conditions set
         forth in SECTIONS 12.3(A) and 12.3(B).

                  (d) If within six (6) months following the Termination Date,
         either Chevron or NGC (an "ACTING PARTY") signs a definitive agreement
         concerning, or issues a public announcement contemplating consummation
         of, an Alternative Transaction or a Significant Disposition with any
         Person or Affiliate of such Person who, prior to the Termination Date,
         has made or caused to be made a proposal to such Acting Party
         communicating price terms for an Alternative Transaction or a
         Significant Disposition, then the Acting Party shall pay to the other
         party, on the first Business Day following such action, the amount of
         $30 million in liquidated damages by wire transfer of immediately
         available funds to an account designated by the other party; provided,
         however, that in no event shall the Acting Party be obligated to pay
         $30 million in liquidated damages under this SECTION 13.3(D) if this
         Agreement was terminated by the Acting Party as a result of a failure
         by the other party to satisfy any of the conditions set forth in
         SECTION 12.2 and 12.3, as applicable.

                  (e) The parties hereto acknowledge and agree that (i) in no
         event shall more than $30 million in liquidated damages be paid under
         the provisions of paragraphs (b), (c) or (d) above and (ii) in the
         event that either party pays or is obligated to pay $30 million in
         liquidated damages under such sections, each party hereto shall
         thereafter be free to effect an Alternative Transaction or Significant
         Disposition at any time without recourse by any other party.

                  (f) No termination of this Agreement pursuant to SECTIONS
         13.1(D) OR 13.1(E) shall relieve any party hereto of any liability for
         any breach or default by such party hereunder and the parties shall
         have such rights, if any, against each other in respect of any breach
         or default as may exist at law or in equity.

                                       71

                  (g) The termination of this Agreement shall not relieve any
         party of its obligation to pay costs and expenses as provided under
         SECTION 9.4 or its obligations under this SECTION 13.3 of this
         Agreement.


                                   ARTICLE 14

                                 INDEMNIFICATION

         14.1     GENERAL PROVISIONS.

                  (a) This ARTICLE 14 reflects the parties' agreement to limit
         potential recoveries from and after the Closing for breaches of
         representations or warranties, or express indemnities made in this
         Agreement. Nothing in this Article restricts any party from enforcing
         other covenants or other agreements made in this Agreement.

                  (b) The parties hereto agree that the sole recourse, from and
         after the Closing for breach of a representation or warranty made in
         this Agreement shall be indemnities for Loss or Losses, or Net Loss or
         Losses, as provided for in this ARTICLE 14, except as otherwise
         provided in ARTICLE 7 hereof.

                  (c) As used in this Agreement, "LOSS" or "LOSSES" shall mean
         with respect to a specific Discrete Claim (and regardless of whether
         one or more of the following pertain to a particular matter), (A) in
         the case of a Third-Party Claim (hereinafter defined), the sum of all
         actual and reasonable out-of-pocket costs and expenses incurred in
         connection with the investigation and defense thereof, any judgments,
         fines or amounts paid in settlement thereof, and additional losses,
         costs or expenses reasonably incurred to comply with any settlement,
         judgment or order imposed thereby, or otherwise resulting from such
         Third Party Claim which has been finally adjudicated or settled, (B) in
         the case of an Environmental Remediation Claim (hereinafter defined),
         all actual out-of-pocket expenses incurred in connection with the
         clean-up or remediation of the affected property in accordance with the
         terms of the Clean-up Plan but, in all cases, subject to the
         limitations set forth in SECTION 14.6(G), and (C) in the case of any
         complete or partial absence or loss (or impairment) of use of any
         property or asset which is the subject of a representation or warranty
         in this Agreement and which absence or loss (or impairment) of use
         results from or relates to a breach of such representation or warranty,
         an amount equal to the lesser of the damages proximately caused by such
         partial or complete absence or loss (or impairment) of use or the
         necessary replacement cost of such asset. A Loss suffered by an Equity
         Affiliate of a Person shall be deemed suffered by that Person to the
         extent of that Person's equity ownership of the Equity Affiliate.

                  (d) As used in this Agreement, the term "NET LOSSES" shall be
         equal to the product of (i) the cumulative amount of all Losses
         incurred, suffered or paid by the Surviving Corporation under SECTIONS
         6.2 AND 14.3 as of a particular date, MULTIPLIED by (ii) the Chevron
         Casualty Loss Ratio; provided, however, that at such time as the
         aggregate number of shares of Surviving Corporation Common Stock and
         Series A Participating Preferred Stock beneficially owned by the
         Contributing Parties represents

                                       72

         less than 25% of the aggregate number of shares of Surviving
         Corporation Common Stock and Series A Participating Preferred Stock (on
         a fully diluted basis), thereafter the ratio used to calculate Net
         Losses shall be equal to a fraction, (A) the numerator of which is the
         aggregate number of shares of Surviving Corporation Common Stock and
         Series A Participating Preferred Stock beneficially owned by the
         Contributing Parties on the Closing Date or as of the date on which the
         notice covering such claim is provided to the Surviving Corporation,
         whichever is less, and (B) the denominator of which is the aggregate
         number of shares of Surviving Corporation Common Stock and Series A
         Participating Preferred Stock, on a fully diluted basis, on such date,
         LESS the number of shares included in the numerator.

                  (e) For the purposes of this Agreement, the term "DISCRETE
         CLAIM" shall mean any (i) (x) discrete or single occurrence, site
         specific condition, act or other event, whether a breach of a Contract,
         a Release of Hazardous Materials, a violation of an Environmental and
         Safety Law or otherwise, that causes a Loss specified in SECTION
         14.1(C)(A)-(C) and (y) without limiting the scope of clause (x) above,
         in the case of an Environmental Remediation Claim, one or more Releases
         of the same or substantially the same Hazardous Material, from or at
         the same location regardless of whether such Releases resulted from the
         same event or from multiple events over time.

                  (f) Except as provided in ARTICLES 7 and 8, all
         representations and warranties shall survive for a two year period
         following the Closing Date and shall terminate at the expiration of
         such period except with respect to Discrete Claims for which a valid
         notice has been given prior to the expiration of such two year period.
         In order for a notice to be considered "valid" for the purposes of the
         preceding sentence, such notice shall conform in all material respects
         with the applicable requirements set forth in this Agreement,
         including, without limitation, SECTION 14.5(A) (in the case of a notice
         covering a Third-Party Claim), SECTION 14.6(A) (in the case of a notice
         covering an Environmental Remediation Claim) and SECTION 14.7 (in the
         case of a notice covering a Use Claim).

                  (g) Except with respect to matters which are assumed by an
         Indemnifying Party pursuant to the provisions of SECTIONS 14.5 or 14.6
         (and with respect to a matter to which ARTICLE 7 applies), the
         Indemnifying Party shall in no event be obligated to make any payments
         to the Indemnified Party with respect to a Loss or Net Loss (as the
         case may be) resulting from a Discrete Claim covered by a notice
         provided within the survival period of the applicable representation,
         warranty, covenant or agreement unless and until an invoice or
         statement describing in reasonable detail the costs incurred in respect
         of such Loss or Net Loss has been provided by the Indemnified Party to
         the Indemnifying Party. The contents of, and time frames prescribed
         for, the payment of such statements or invoices are governed by
         SECTIONS 14.5(A), 14.6(A) and 14.7 hereof; provided, however, that the
         date on which the Indemnifying Party provides the Indemnified Party
         with such invoice or statement shall not have any effect on the
         survival of the indemnities set forth herein but shall only govern the
         date on which the Indemnified Party is entitled to payment for any Net
         Loss or Losses covered by such indemnities.

         14.2 INDEMNIFICATION BY CHEVRON. Subject to the limitations in SECTION
16.1 and SECTION 14.4 and the other provisions of this ARTICLE 14, Chevron
agrees to defend, indemnify and hold harmless the Surviving Corporation and its
Subsidiaries and Affiliates and their respective officers, directors, employees,
agents and Affiliates (the "NGC INDEMNITEES") against any and all Losses
suffered, incurred or paid by any of them caused by or arising from a breach of
any representation, warranty, covenant or agreement made by Chevron and
contained in this Agreement; provided, however, that in evaluating whether there
has been a breach of a representation, warranty, covenant or agreement (each, a
"REPRESENTATION") to which the indemnification obligations contained in this
section are applicable, any provision of the applicable Representation limiting
it to matters within the "knowledge" or "best knowledge" of a party or matters
having a Material Adverse Effect shall be disregarded, it being intended that
the limitations on the rights of the parties contained in SECTION 14.4 below
shall determine whether a matter constitutes a breach of the applicable
Representation which is properly a subject of indemnification under this ARTICLE
14. This SECTION 14.2 shall not apply to a breach by Chevron of any
representations and warranties regarding matters specifically covered by ARTICLE
7.

         14.3 INDEMNIFICATION BY NGC. Subject to the limitations in SECTION 16.1
and SECTION 14.4 and the other provisions of this ARTICLE 14, NGC agrees to
defend, indemnify and hold harmless Chevron and its Subsidiaries and Affiliates
(other than Newco or, upon consummation of the Merger, the Surviving
Corporation, and their respective officers, directors, employees, agents and
Affiliates (the "CHEVRON INDEMNITEES") against any and all Losses suffered,
incurred or paid by any of them or the Surviving Corporation caused by or
arising from a breach of any representation, warranty, covenant or agreement
contained in this Agreement; provided, however, that in evaluating whether there
has been a breach of a Representation to which the indemnification obligations
contained in this section are applicable, any provision of the applicable
Representation limiting it to within the "knowledge" or "best knowledge" of a
party or matters having a Material Adverse Effect shall be disregarded, it being
intended that the limitations on the rights of the parties contained in SECTION
14.4 below shall determine whether a matter constitutes a breach of the
applicable Representation which is properly a subject of indemnification under
this ARTICLE 14. This SECTION 14.3 shall not apply to a breach by NGC of any
representations and warranties regarding matters specifically covered by ARTICLE
7.

         14.4 LIMITATION OF LIABILITY. Except for the indemnities provided in
ARTICLE 7 of this Agreement:

                  (a) Chevron shall not be obligated to indemnify the NGC
         Indemnitees unless and until the cumulative amount of all Losses
         incurred, suffered or paid by all of the NGC Indemnitees under SECTION
         6.1 AND 14.2 exceeds $10 million in the aggregate or unless the
         cumulative amount of (i) all Losses actually incurred, suffered or paid
         by all of the Chevron Indemnities hereunder and (ii) all Net Losses
         indirectly suffered by the Chevron Indemnities resulting from Losses
         suffered by the Surviving Corporation under SECTIONS 6.2, AND 14.3
         exceeds $10 million in the aggregate, whereupon the NGC Indemnitees
         shall be entitled to indemnification hereunder for the full amount of
         all such Losses and shall thereafter be entitled to indemnification of
         Losses as such Losses are incurred (subject to paragraph (c) below).

                                       74

                  (b) The Surviving Corporation shall not be obligated to
         indemnify the Chevron Indemnitees under SECTIONS 6.2, AND 14.3 and
         unless and until the cumulative amount of (i) all Losses actually
         incurred, suffered or paid by all of the Chevron Indemnitees hereunder
         and (ii) all Net Losses indirectly suffered by the Chevron Indemnitees
         resulting from Losses suffered by the Surviving Corporation under
         SECTIONS 6.2 AND 14.3 exceeds $10 million in the aggregate, or unless
         the cumulative amount of all Losses actually incurred, suffered or paid
         by the NGC Indemnities under SECTIONS 6.1 AND 14.2 exceeds $10 million,
         whereupon the Chevron Indemnitees shall be entitled to indemnification
         hereunder for the full amount of all such Losses and Net Losses and
         shall thereafter be entitled to indemnification of Losses and Net
         Losses thereafter as such Losses and Net Losses are incurred (subject
         to paragraph (c) below). In computing the amount of any Net Loss
         arising from any Environmental Remediation Claim, there shall be
         deducted from the amount of the applicable Loss relating to the assets
         described in SCHEDULE 14.4 hereto, an amount up to the amount set forth
         in such Schedule relating to such asset to take into account the
         accruals for environmental purposes previously taken by NGC with
         respect to such assets.

                  (c) Neither Chevron nor the Surviving Corporation shall be
         obligated to indemnify the NGC Indemnitees or the Chevron Indemnitees,
         respectively, under SECTIONS 6.1, 6.2, 14.2 AND 14.3, as applicable,
         for a particular Discrete Claim unless the collective Losses incurred,
         suffered or paid by the NGC Indemnitees or the Chevron Indemnitees, as
         applicable, with respect to such claim exceeds $200,000. If the amount
         of collective Losses incurred, suffered or paid in connection with such
         Discrete Claim is less than $200,000, such Losses shall not be counted
         in calculating the aggregate amount of all Losses for purposes of
         sub-paragraphs (a) and (b) above.

         14.5 INDEMNIFICATION PROCEDURES: THIRD PARTY CLAIMS. A party claiming
indemnification under this Agreement (the "INDEMNIFIED PARTY") as a result of a
liability owed by a party hereto to a third party or a claim otherwise advanced
by a third party against a party hereto, either actual or asserted by the third
party, including any claims brought under ARTICLES 6, 8 AND 14 (but specifically
excepting any claim brought under ARTICLE 7) (each, a "THIRD-PARTY CLAIM")
against the Indemnified Party shall follow the following procedures to assert
and resolve such claims for indemnification:

                  (a) An Indemnified Party claiming indemnification under this
         Agreement as a result of a Third-Party Claim shall (i) notify the Party
         from whom indemnification is sought (the "INDEMNIFYING PARTY") of any
         Third-Party Claim or Claims asserted against the Indemnified Party
         which could give rise to a right of indemnification under this
         Agreement and (ii) transmit to the Indemnifying Party a written notice
         ("CLAIM NOTICE") describing in reasonable detail the nature of the
         Third Party Claim, a copy of all papers served with respect to such
         Third-Party Claim (if any), an estimate of the amount of damages
         attributable to the Third-Party Claim and the basis of the Indemnified
         Party's request for indemnification under this Agreement.

         Within sixty (60) days after receipt of any Claim Notice (the "ELECTION
PERIOD"), the Indemnifying Party shall notify the Indemnified Party (i) whether
the Indemnifying Party disputes its potential liability to the Indemnified Party
under this ARTICLE 14 with respect to such

                                       75

Third-Party Claim and (ii) whether the Indemnifying Party desires to defend the
Indemnified Party against such Third-Party Claim.

                  (b) If the Indemnifying Party notifies the Indemnified Party
         within the Election Period that the Indemnifying Party does not dispute
         its potential liability to the Indemnified Party under this SECTION
         14.5(B) and that the Indemnifying Party elects to assume the defense of
         the Third-Party Claim, then the Indemnifying Party shall have the right
         to defend, at its sole cost and expense, such Third-Party Claim by all
         appropriate proceedings, which proceedings shall be prosecuted
         diligently by the Indemnifying Party to a final conclusion or settled
         at the discretion of the Indemnifying Party in accordance with this
         SECTION 14.5(B). The Indemnifying Party shall have full control of such
         defense and proceedings; provided, however, that the Indemnifying Party
         may not settle a Third-Party Claim (unless the settlement contains a
         full and complete release of the Indemnified Party) without the written
         consent of the Indemnified Party, which consent shall not be
         unreasonably withheld. The Indemnified Party is hereby authorized, at
         the sole cost and expense of the Indemnifying Party (but only if the
         Indemnified Party is actually entitled to indemnification hereunder or
         if the Indemnifying Party assumes the defense with respect to the
         Third-Party Claim), to file, during the Election Period, any motion,
         answer or other pleadings which the Indemnified Party shall deem
         necessary or appropriate to protect its interests or those of the
         Indemnifying Party and which are not prejudicial to the Indemnifying
         Party (it being understood and agreed that if an Indemnified Party
         takes any such action which is prejudicial and conclusively causes a
         final adjudication which is adverse to the Indemnifying Party, the
         Indemnifying Party shall be relieved of its obligations hereunder with
         respect to such Third-Party Claim). If requested by the Indemnifying
         Party, the Indemnified Party agrees, at the sole cost and expense of
         the Indemnifying Party, to cooperate with the Indemnifying Party and
         its counsel in contesting any Third-Party Claim which the Indemnifying
         Party elects to contest, including, without limitation, the making of
         any related counterclaim against the Person asserting the Third-Party
         Claim or any cross-complaint against any Person. The Indemnified Party
         may participate in, but not control, any defense or settlement of any
         Third-Party Claim controlled by the Indemnifying Party pursuant to this
         SECTION 14.5(B) and shall bear its own costs and expenses with respect
         to such participation.

                  (c) (i) If the Indemnifying Party fails to notify the
         Indemnified Party within the Election Period that the Indemnifying
         Party elects to defend the Indemnified Party pursuant to SECTION
         14.5(B), (ii) if the Indemnifying Party elects to defend the
         Indemnified Party pursuant to SECTION 14.5(B) but fails to diligently
         and promptly prosecute or settle the Third-Party Claim, or (iii) if the
         Indemnified Party shall have reasonably concluded that there is a
         conflict of interest between the Indemnifying Party and Indemnified
         Party such that joint representation in the conduct of the defense or
         settlement of such Third-Party Claim is inappropriate, then the
         Indemnified Party shall have the right to defend, at the sole cost and
         expense of the Indemnifying Party, the Third-Party Claim by all
         appropriate proceedings, which proceedings shall be promptly and
         vigorously prosecuted by the Indemnified Party to a final conclusion or
         settled. The Indemnified Party shall have full control of such defense
         and proceedings; provided, however, that the Indemnified Party may not
         enter into, without the Indemnifying Party's consent, which shall not
         be unreasonably withheld, any compromise or settlement of such

                                       76

         Third-Party Claim. Notwithstanding the foregoing, if the Indemnifying
         Party has delivered a written notice to the Indemnified Party to the
         effect that the Indemnifying Party disputes its potential liability to
         the Indemnified Party under this ARTICLE 14 and if such dispute is
         resolved in favor of the Indemnifying Party by final, nonappealable
         order of a court of competent jurisdiction, the Indemnifying Party
         shall not be required to bear the costs and expenses of the Indemnified
         Party's defense pursuant to this SECTION 14.5 or of the Indemnifying
         Party's participation therein at the Indemnified Party's request and
         the Indemnified Party shall reimburse the Indemnifying Party in full
         for all costs and expenses of such litigation. The Indemnifying Party
         may participate in, but not control, any defense or settlement
         controlled by the Indemnified Party pursuant to this SECTION 14.5, and
         the Indemnifying Party shall bear its own costs and expenses with
         respect to such participation.

                  (d) Payments of all amounts owing by the Indemnifying Party
         with respect to a Third-Party Claim shall be made within thirty (30)
         days after the latest of (i) the settlement of the Third-Party Claim,
         (ii) the expiration of the period for appeal of a final adjudication of
         such Third-Party Claim or (iii) the expiration of the period for appeal
         of a final adjudication of the Indemnifying Party's liability to the
         Indemnified Party under this Agreement.

         14.6 INDEMNIFICATION PROCEDURES: ENVIRONMENTAL REMEDIATION CLAIMS. An
Indemnified Party claiming indemnification under this Agreement for costs and
expenses necessary to take corrective action to remediate the assets comprising
the Chevron Facilities or the NGC Facilities or Former NGC Facilities, as
applicable, resulting from the indemnities provided in ARTICLE 6 (an
"ENVIRONMENTAL REMEDIATION CLAIM") shall follow the following procedures to
assert and resolve such claims for indemnification:

                  (a) An Indemnified Party claiming indemnification under this
         Agreement as a result of a Environmental Remediation Claim shall (i)
         notify the Indemnifying Party of such Environmental Remediation Claim
         or Claims which could give rise to a right of indemnification under
         this Agreement and (ii) transmit to the Indemnifying Party a written
         plan ("CLEAN-UP PLAN") describing in reasonable detail (i) the nature
         of the Environmental Remediation Claim, (ii) the scope and nature of
         remedial and clean-up operations proposed to be undertaken by the
         Indemnified Party to correct the Environmental Remediation Claim and
         (iii) an estimate of the amount of damages attributable to the
         Environmental Remediation Claim that are covered by ARTICLE 6 and the
         basis of the Indemnified Party's request for indemnification under this
         Agreement.

                           Within sixty (60) days after receipt of any Clean-up
         Plan (the "ENVIRONMENTAL ELECTION PERIOD"), the Indemnifying Party
         shall notify the Indemnified Party (i) whether the Indemnifying Party
         disputes its potential liability to the Indemnified Party under this
         SECTION 14.6 with respect to such Environmental Remediation Claim and
         (ii) whether the Indemnifying Party (A) accepts the Clean-up Plan or
         (B) desires to take corrective measures, at its sole cost and expense,
         to remediate the property associated with the Environmental Remediation
         Claim.

                                       77


            (b) In the event that the Indemnifying Party notifies the
         Indemnified Party within the Environmental Election Period that the
         Indemnifying Party does not dispute its potential liability to the
         Indemnified Party under this ARTICLE 14 and that the Indemnifying Party
         accepts the Indemnified Party's Clean-up Plan, then the Indemnified
         Party shall have the right to proceed in remediating the property or
         properties subject to the Environmental Remediation Claims in
         accordance with the Clean-up Plan; provided, however, that the
         Indemnified Party shall use its best efforts to conduct such remedial
         and clean-up operations in conformity with the Clean-up Plan.

                  (c) In the event that the Indemnifying Party fails to notify
         the Indemnified Party within the Environmental Election Period
         regarding the Clean-up Plan, then the Indemnifying Party shall be
         deemed to have conclusively approved the Clean-up Plan and the costs
         associated with implementing such plan and the Indemnified Party shall
         have the right to proceed in remediating the property or properties
         subject to the Environmental Remediation Claims in accordance with the
         Clean-up Plan; provided, however, that the Indemnified Party shall use
         its best efforts to conduct such remedial and clean-up operations in
         conformity with the Clean-up Plan.

                  (d) Subject to the limitations set forth in SECTION 14.4, the
         Indemnified Party shall invoice the Indemnifying Party as soon as
         practicable following the end of a calendar month for any and all
         out-of-pocket costs and expenses incurred by the Indemnified Party in
         implementing its Clean-up Plan during such month and the Indemnifying
         Party shall promptly reimburse the Indemnified Party for any and all
         such costs and expenses immediately after receipt of such invoice.

                  (e) In the event that the Indemnifying Party notifies the
         Indemnified Party within the Environmental Election Period that the
         Indemnifying Party does not dispute its potential liability to the
         Indemnified Party under this ARTICLE 14 but desires to take corrective
         action itself to remediate the property subject to the Environmental
         Remediation Claim, then the Indemnifying Party shall have the right to
         assume operations for the remediation of the property and shall take
         any and all corrective measures, at its sole cost and expense, to
         remediate such property and the Indemnified Party shall provide the
         Indemnifying Party at the sole cost, risk and expense of the
         Indemnifying Party (to the extent necessary) with reasonable access to
         such property necessary to take any and all appropriate actions and
         measures to remediate such property in accordance with this SECTION
         14.6; provided, however, that in the event that the Indemnifying Party
         rejects the Clean-up Plan and undertakes to remediate such property,
         then the Indemnifying Party shall indemnify and hold harmless the
         Indemnified Party for any and all Losses suffered, incurred or paid by
         the Indemnified Party arising out of any acts or omissions by the
         Indemnifying Party in remediating such property pursuant to this
         SECTION 14.6(E), including, without limitation, any failure to fully
         remediate the condition that was the subject of the Clean-up Plan; and
         provided further, that the Indemnified Party shall have the right to
         monitor the progress of the clean-up of the affected property by the
         Indemnifying Party and shall have access to all personnel of the
         Indemnifying Party (whether employees, agents or otherwise), records,
         plans and other information concerning the clean-up of the affected
         property that the Indemnified Party deems necessary and advisable under
         the circumstances. If requested by the Indemnifying

                                       78

         Party, the Indemnified Party agrees, at the sole cost and expense of
         the Indemnifying Party, to cooperate with the Indemnifying Party and
         its experts and agents in conducting any remedial operations on the
         property subject to the Environmental Remediation Claim.

                  (f) Regardless of whether the Indemnified Party or the
         Indemnifying Party cleans-up the property that is subject to an
         Environmental Remediation Claim, each party recognizes and acknowledges
         that it should use its reasonable best efforts to cooperate with the
         other party to implement the Clean-up Plan or to otherwise conduct the
         clean-up operations.

                  (g) Regardless of whether the Indemnified Party or the
         Indemnifying Party cleans up the property that is subject to the
         Environmental Remediation Claim, the Indemnifying Party shall only be
         responsible for Losses or costs of clean-up or remediation that are (i)
         required to bring such property (as such property is used on the
         Closing Date) in compliance with the minimum standards imposed by the
         Environmental and Safety Laws in effect on the Closing Date or (ii)
         Losses arising from acts or omissions of the Indemnifying Party under
         paragraph (e) above. NGC agrees, as a predecessor in interest to the
         Surviving Corporation, that the Surviving Corporation shall use
         commercially reasonable efforts to complete all Clean-up Plans by the
         seventh anniversary of the Closing Date, except to the extent that such
         efforts are not in accordance with good and prudent industry standards
         or would cause the Surviving Corporation to breach any of its
         representations, warranties, covenants or agreements under this
         Agreement.

                  (h) In the event that the Surviving Corporation is expecting
         to conduct a Clean-up Plan as of August 30, 2003, then the Surviving
         Corporation shall, as soon as practicable after August 30, 2001, but in
         any event within 90 calendar days prior to August 30, 2003, provide
         Chevron with a schedule (the "ENVIRONMENTAL SCHEDULE") setting forth in
         reasonable detail (i) each Clean-up Plan that it expects to still be
         conducting on such date by the Surviving Corporation, (ii) an estimate
         of the amount of time that will be required to complete each such
         Clean-up Plan, (iii) what measures, if any, could be undertaken by the
         Surviving Corporation to expedite any of such Clean-up Plans, even if
         such measures are not the most economical or cost efficient measures
         that can be employed to clean-up or remediate the affected property
         ("ADDITIONAL MEASURES") and (iv) a reasonable estimate of the
         additional costs that would be associated with implementing such
         Additional Measures. In order to expedite any Clean-up Plan, Chevron
         may request in writing not later than 30 days prior to August 30, 2003,
         (i) that the Surviving Corporation modify such Clean-up Plan by
         implementing such Additional Measures which are reasonable and
         appropriate under the circumstances and the Surviving Corporation shall
         use commercially reasonable efforts to implement such Additional
         Measures (and the implementation of such measures shall not diminish in
         any respect Chevron's indemnification obligations hereunder) or (ii) to
         assume clean-up obligations with respect to an affected property
         covered by such Clean-up Plan (subject to the provisions of SECTION
         14.6(E) above) and, in such event, Chevron may implement such
         Additional Measures (at Chevron's sole cost and expense) as Chevron
         deems appropriate under the circumstances. In no event shall any
         Additional Measures be undertaken by Chevron or the Surviving
         Corporation, if such Additional Measures would

                                       79

         not be as effective in cleaning up or remediating the affected property
         or would expose their employees or other agents or contractors to
         increased risk. This paragraph (h) shall in no way diminish Chevron's
         indemnification obligations under this SECTION 14.6 but shall only
         provide Chevron with certain limited rights with respect to clean-up
         operations and remediations being conducted after August 30, 2003 which
         are covered by the indemnity of this ARTICLE 14.

                  (i) All other environmental claims with regard to the Chevron
         Facilities or NGC Facilities or Former NGC Facilities that do not
         involve corrective or remedial operations shall be addressed under
         SECTION 14.5 or SECTION 14.7, as applicable.

         14.7 INDEMNIFICATION PROCEDURES: ABSENCE, LOSS OR IMPAIRMENT OF USE OF
PROPERTY. An Indemnified Party claiming indemnification under this Agreement for
Losses resulting from a complete or partial absence or loss (or impairment of
use) of any property or asset ("USE CLAIMS"), shall transmit to the Indemnifying
Party a written notice (the "USE NOTICE") describing in reasonable detail the
nature of the Use Claim, a non-binding estimate of the Loss attributable to such
Use Claim and the basis of the Indemnified Party's request for indemnification
under this Agreement. If the Indemnifying Party does not notify the Indemnified
Party within sixty (60) days from its receipt of the Use Notice that the
Indemnifying Party disputes such Use Claim, the Use Claim specified by the
Indemnified Party in the Indemnity Notice shall be deemed to be an admission of
liability of the Indemnifying Party hereunder in at least the amount specified
in the Indemnity Notice. If the Indemnifying Party has timely disputed the
validity or amount of such Use Claim, as provided above, then the parties shall
attempt to resolve through any manner that they deem reasonable under the
circumstances, failing which the Indemnified Party may institute appropriate
legal action. Payments of all amounts owing by the Indemnifying Party with
respect to any Use Claim shall be made within thirty (30) days after the later
of (i) the expiration of the sixty-day (60-day) Indemnity Notice period or (ii)
the expiration of the period for appeal of a final adjudication of the
Indemnifying Party's liability to the Indemnified Party under this Agreement.

                                   ARTICLE 15

                              POST-CLOSING MATTERS

         15.1 CORPORATE NAMES. NGC expressly acknowledges and agrees that the
name "Chevron," and any derivation thereof shall not constitute a Contributed
Asset and shall remain the exclusive property of Chevron. Neither NGC nor any
Affiliate of NGC shall, in any way, infringe upon Chevron's use or rights to
such name (and any derivation thereof). Within six months after Closing, NGC
shall remove all trademarks and tradenames containing the name Chevron or the
Chevron logo from any of the assets or properties comprising the Contributed
Businesses. Chevron expressly acknowledges and agrees that the name "Warren
Petroleum Company" and any derivation thereof constitutes a part of Contributed
Businesses and shall become the exclusive property of the Surviving Corporation
upon consummation of the transactions contemplated hereby. Neither Chevron nor
any Affiliate of Chevron (except Newco or the Surviving Corporation or its
Subsidiaries) shall, in any way, infringe upon Surviving Corporation's use or
rights to such name (and any derivation thereof).


                                       80

         15.2 OPTIONS. NGC and the Surviving Corporation shall, in accordance
with the procedures set forth in Paragraph IX(d) of the NGC Corporation EEP,
Section 13 of the NGC Option Plan and Section 3(a) of the Warrant, cause the
number and class of shares of NGC Corporation Stock covered by each Option
outstanding as of the Effective Time to be amended so that immediately after the
Effective Time such Option shall cover the same number and class of shares of
Surviving Corporation Common Stock to which the holder of such Option would have
been entitled pursuant to the terms of this Agreement if, immediately prior to
the Effective Time, such holder had been the holder of record of the number of
shares of NGC Corporation Stock then covered by such Option.

         15.3     DEFINITIVE CONSIDERATION ADJUSTMENT.

                  (a) As promptly as practicable but in no event later than 90
         calendar days after the Closing Date, Chevron shall deliver to
         Surviving Corporation (after consultation with Surviving Corporation),
         a schedule (the "PRELIMINARY ADJUSTMENT SCHEDULE") setting forth in
         reasonable detail the calculation of the actual Consideration
         Adjustments contemplated by paragraphs (a) through (h) of SECTION 2.3,
         but shall use the actual values and quantities on the Closing Date for
         the calculations to be made at Closing pursuant to the applicable
         provisions of SECTION 2.3 and shall use the same procedures included in
         SECTION 2.3(H) for the calculation relating to the Contributed Warren
         Business provided in such section. In the event NGC and Chevron shall
         have reached agreement as to the Agreed Value of a Retained Asset for
         which a Minimum Value was used for purposes of SECTION 2.4 or pursuant
         to the provisions of SECTION 15.4, then such adjustments shall also be
         made in the Preliminary Adjustment Schedule.

                  (b) The Preliminary Adjustment Schedule shall be subject to
         review by Surviving Corporation. In reviewing the Preliminary
         Adjustment Schedule, Surviving Corporation shall have the right to
         communicate with, and to review the work papers, schedules, memoranda
         and other documents prepared or reviewed by Chevron during the
         preparation of the Preliminary Adjustment Schedule (including, without
         limitation, the income statements used to derive net income and
         depreciation and amortization included therein) and thereafter shall
         have access to all relevant employees of Chevron and to all relevant
         books and records, all to the extent reasonably required by Surviving
         Corporation in order to complete its review of the Preliminary
         Adjustment Schedule. Within 60 calendar days after its receipt of the
         Preliminary Adjustment Schedule, Surviving Corporation shall advise
         Chevron whether, based on such review, it has any exceptions to the
         Preliminary Adjustment Schedule. Unless Surviving Corporation shall
         deliver to Chevron within such 30 calendar day period a letter
         specifying in reasonable detail any such exceptions, the Preliminary
         Adjustment Schedule shall be conclusive and binding on Chevron and the
         Surviving Corporation. If Surviving Corporation shall submit a letter
         detailing any exceptions to the Preliminary Exception Schedule, then
         the Surviving Corporation and Chevron shall mutually agree on which
         exceptions shall result in adjustments to the Preliminary Consideration
         Adjustment. The "DEFINITIVE CONSIDERATION ADJUSTMENT" shall mean the
         Preliminary Consideration Adjustment, with any adjustment required by
         the immediately preceding sentence.


                                       81

                           (c)(i) If the Definitive Consideration Adjustment is
                  greater than the Estimated Consideration Adjustment, Chevron
                  shall pay the Surviving Corporation the difference, together
                  with interest thereon at a rate of 6% per annum during the
                  period commencing on the Closing Date and continuing through
                  and including the day preceding the payment date.

                           (ii) If the Definitive Consideration Adjustment is
                  less than the Estimated Consideration Adjustment, the
                  Surviving Corporation shall pay Chevron the difference,
                  together with interest thereon at a rate of 6% per annum
                  during the period commencing on the Closing Date and
                  continuing through and
                  including the day preceding the payment date.

                           (iii) Any payment required by paragraph (a) or (b) of
                  this SECTION 15.3 shall be made on the third Business Day
                  after the Definitive Consideration Adjustment is determined
                  via wire transfer to an account designated by the party to
                  whom the payment is owed. Such account shall be designated by
                  such party on the date the Definitive Consideration Adjustment
                  is made.

         15.4 TRANSFERS OF RETAINED ASSETS DURING THE INTERIM PERIOD. During the
         period commencing on the Closing Date and continuing through and
         including the first anniversary thereof (the "INTERIM PERIOD"), Chevron
         shall use its best efforts to transfer to the Surviving Corporation any
         Retained Asset or reasonably equivalent economic value therefor that is
         reasonably acceptable to the Surviving Corporation. In the event that
         Chevron is able to transfer the Retained Asset to the Surviving
         Corporation during the Interim Period, the Surviving Corporation shall
         make a cash payment to Chevron equal to (i) the sum of the Minimum
         Value or Agreed Value (as the case may be) of the Retained Asset plus
         interest thereon at a rate of 6% per annum from the Closing Date
         through and including the date on which the Retained Asset is
         transferred to the Surviving Corporation, LESS (ii) any net operating
         cash flow attributable to such Retained Asset during such period. Any
         payment made by the Surviving Corporation pursuant to this SECTION 15.4
         shall be made on the third Business Day after the Retained Asset is
         transferred to the Surviving Corporation and shall be made to a bank
         account designated by Chevron in writing no later than the date on
         which such asset is transferred.

         15.5     FINAL ADJUSTMENT FOR RETAINED ASSETS.

                  (a) If NGC and Chevron shall have disagreed as to the fair
         value of a Retained Asset pursuant to SECTION 2.4 and such asset was
         not transferred during the Interim Period or the value of such asset
         was not resolved pursuant to SECTION 15.3, then within five Business
         Days after the first anniversary of the Closing Date, the Surviving
         Corporation shall refer the matter for resolution by an investment
         banking firm without a conflict of interest (the "INDEPENDENT VALUE
         EXPERT") to be selected by Lehman Brothers and Goldman Sachs (the
         "VALUE EXPERTS") in accordance with the provisions of this SECTION
         15.5, by giving notice to Chevron of its election to do so. If the
         Surviving Corporation fails to provide Chevron with proper notice under
         this SECTION 15.5, then the Minimum Value shall be conclusively deemed
         to be the fair value of the Retained Asset and shall be final and
         binding on the parties.

                                                        82

<PAGE>




                  (b) Within ten Business Days after referring a matter to the
         Value Experts in accordance with paragraph (a) of this SECTION 15.5,
         the Value Experts shall select the Independent Value Expert. Within
         five Business Days thereafter, each party shall deliver to the other
         party and to the Independent Value Expert a notice setting forth in
         reasonable detail the fair value such party ascribes to each Retained
         Asset and the basis of such valuation (the "DECISION NOTICE"). Within
         five Business Days after receiving the Decision Notices, the
         Independent Value Expert shall choose the fair value of the Retained
         Asset as set forth in one party's Decision Notice and shall be in no
         way empowered to choose a different value. The Independent Value Expert
         shall adopt the Decision Notice that, in the best judgment of such
         Independent Value Expert, is the closer of the two Decision Notices to
         the fair value of the Retained Asset. In making such determination the
         Independent Value Expert shall apply the valuation principles utilized
         by the parties in connection with the transactions contemplated by this
         Agreement.

                  (c) The decision of the Independent Value Expert shall be in
         writing and shall be final and binding upon the parties, and may be
         entered in any court of competent jurisdiction upon the application of
         either party. If applicable, the expenses of the Independent Value
         Expert shall be borne by the party whose Decision Notice is not chosen.
         Each party shall bear the costs of its own counsel, witnesses (if any)
         and employees.

                  (d)(i) If the Minimum Value is less than the value chosen by
         the Independent Expert with respect to such Retained Asset (the
         "DEFINITIVE VALUE"), Chevron shall pay the Surviving Corporation the
         difference, together with interest thereon at a rate of 6% per annum
         during the period commencing on the Closing Date and continuing through
         and including the day preceding the payment date.

                  (ii) If the Minimum Value is greater than the Definitive
         Value, the Surviving Corporation shall pay Chevron the difference,
         together with interest thereon at a rate of 6% per annum during the
         period commencing on the Closing Date and continuing through and
         including the day preceding the payment date.

                  (iii) Any payment required by this SECTION 15.5 shall be made
         on the third Business Day after the Definitive Value is determined via
         wire transfer to an account designated by the party to whom the payment
         is owed. Such account shall be designated by such party on the date the
         Definitive Value is established.

         15.6     ADJUSTMENT REGARDING LONDON OPERATIONS.

                  (a) Chevron agrees, as a contingent reduction to the
         Consideration due to Chevron hereunder, that if the London Earnings for
         the 1997, 1998 and 1999 calendar years (the "OPERATIVE YEARS"), shall
         equal at least a total of $54 million, as reflected in the calculations
         contained in a notice sent by Surviving Corporation to Chevron (the
         "LONDON NOTICE"), Chevron shall pay to Surviving Corporation, as an
         additional adjustment to the Consideration payable hereunder, the sum
         of $33 million plus an amount equal to interest on such sum from the
         Closing Date to the date of payment at

                                       83

         a rate of 6% per annum, compounded semi-annually. If the London
         Earnings for the Operative Years are less than $30 million, there shall
         be no payment under this section. If the London Earnings for the
         Operative Years are more than $30 million but less than $54 million (as
         reflected in the London Notice), Chevron shall pay to Surviving
         Corporation an amount determined by multiplying $33 million by a
         fraction, the numerator of which shall be the total London Earnings for
         the Operative Years in excess of $30 million and the denominator of
         which shall be $24 million, plus an amount equal to interest on such
         sum from the Closing Date to the date of payment at a rate of 6% per
         annum, compounded semi-annually. As used herein, the term "London
         Earnings" shall mean the amounts contributed to NGC's net income from
         the London Operations determined on a basis consistent with generally
         accepted accounting principles (including reductions for the effect of
         any appropriate income taxes); provided, however, that such earnings
         shall exclude all earnings (a) derived from or attributable to the
         presently existing contracts comprising a part of the Contributed
         Warren Business, (b) attributable to any interest in Accord in addition
         to NGC's present 49% interest therein, (c) attributable to
         contributions made by NGC to Accord or NGC International (other than
         the return of earnings distributed after the Closing by Accord or NGC
         International to NGC plus an amount equal to interest thereon at 6% per
         annum from the time of such distribution to the time of such return)
         and (d) derived from or attributable to any project, whether an
         acquisition of properties or a project requiring capital expenditures,
         which is financed with funds other than internal cash of Accord, NGC
         International and their respective Subsidiaries (i) to the extent the
         amount so financed exceeds 50% of the total cost of such project (in
         which case, London Earnings shall be adjusted by the decreasing the
         earnings derived from such project by multiplying such earnings by a
         fraction, the numerator of which shall be 50 and the denominator of
         which shall be the percentage to which such project has been financed),
         or (ii) if there are guarantees given or collateral supplied in
         connection with such financing by parties other than Accord, NGC
         International and their respective subsidiaries. In addition, earnings
         from acquisitions or capital investments shall constitute London
         Earnings only to the extent such expenditures are made to facilitate
         the application and leverage of NGC's core competencies and sources of
         competitive advantage related to marketing and trading energy commodity
         products and services. For purposes of this provision, NGC's
         international investment philosophy generally will be to minimize its
         equity participation and capital projects consistent with establishing
         a sufficient position to optimize its trading and marketing businesses.
         Chevron shall have a period of 90 days after any such London Notice to
         audit the calculation of the adjustments contemplated hereunder. The
         payment of the amounts due with respect to the London Notice shall be
         made within 15 days after the expiration of such ninety day period.

                  (b) If Chevron does not agree with the computation of payment
         due regarding London Earnings, it shall promptly provide notice to a
         Surviving Corporation, and in any event prior to the expiration of such
         90 days period set forth in paragraph (a) above. The Parties shall
         thereafter negotiate in a good faith attempt to resolve their
         differences. If the Parties are unable to resolve such differences,
         either Party may elect to refer the matter for resolution by an
         Arbitrator, who shall be a partner reasonably acceptable to each Party
         of a nationally recognized accounting firm without a conflict of
         interest. If the Parties are unable to agree on an Arbitrator under the
         provisions of the preceding

                                       84

         sentence within 90 additional days after the expiration of such 90 day
         period, either Party may file an action in a court of law seeking
         judicial resolution of such dispute.

         15.7     INSURANCE.

                           (a) Chevron, Newco and NGC acknowledge that Chevron
                  Corporation has maintained worldwide programs of property and
                  liability insurance coverage for itself and its Affiliates,
                  including with respect to the Contributed Businesses and the
                  Contributed West Texas LPG Pipeline Business. Such programs
                  have been designed to achieve a cost-effective, coordinated
                  risk-management package for the entire corporate group. All of
                  the insurance policies through which such worldwide programs
                  of coverage are presently or have previously been provided are
                  herein called the "CHEVRON CORPORATION POLICIES."

                           (b) It is the understanding and intention of Chevron,
                  Newco and NGC that subject to SECTION 15.7(D) below:

                           (i) from and after the Closing, no insurance coverage
                  shall be provided under the Chevron Corporation Policies
                  relating to the Contributed Businesses and the Contributed
                  West Texas LPG Pipeline Business; and

                                    (ii) from and after the Closing, no claims
                           regarding any matter whatsoever, whether or not
                           arising from events occurring prior to the Closing,
                           shall be made against or with respect to the Chevron
                           Corporation Policies by the Surviving Corporation.

                           (c) Subject to SECTION 15.7(D) below, Newco, NGC and
                  the Surviving Corporation, on behalf of itself, its successors
                  and assigns, hereby releases, to the extent permitted by
                  applicable law, Chevron and its Affiliates from any claim made
                  after the Closing against or with respect to any of the
                  Chevron Corporation Policies by or through Newco, NGC or the
                  Surviving Corporation. Such release shall cover, without
                  limitation, any claim by an insurer for reinsurance,
                  retrospective premium payment or prospective premium increases
                  attributable to any such claim.

                           (d) Nothing contained in the foregoing provision of
                  this SECTION 15.7 shall in any way limit, impair or constitute
                  a release or discharge of any right of Surviving Corporation
                  or obligation of Chevron with respect to any representation,
                  warranty, covenant, agreement, indemnity or other obligation
                  of Chevron contained in this Agreement (regardless of whether
                  the same was, is or may be covered by any insurance described
                  herein), all of which rights and obligations shall continue in
                  full force and effect notwithstanding any other provision of
                  this SECTION 15.7.

                           (e) To the best of Chevron's knowledge, neither
                  Chevron nor any prior owner of Warren Petroleum Company, or
                  any of the assets comprising Warren

                                       85


                  Petroleum Company, has purchased Third Party Insurance
                  Policies specifically covering Warren Petroleum Company or
                  certain of the assets that comprise Warren Petroleum Company.
                  In the event that Chevron locates or otherwise identifies any
                  such Third Party Insurance Policies, Chevron shall promptly
                  notify the Surviving Corporation and shall use all
                  commercially reasonable efforts to provide the Surviving
                  Corporation with any benefits that Chevron may have under such
                  insurance policies; provided, however, that Surviving
                  Corporation shall reimburse Chevron for any out-of-pocket
                  costs incurred by Chevron in assisting the Surviving
                  Corporation in deriving any such benefits; and provided
                  further, that in no event shall Chevron be obligated to
                  provide the Surviving Corporation with any such benefits in
                  the event that such insurance policies cover assets other than
                  the Contributed Warren Business or could be included in a
                  comprehensive settlement that is being contemplated by Chevron
                  as of the date hereof.

         15.8 INDEMNIFICATION PRINCIPLES. NGC acknowledges that upon
consummation of the Combination the Surviving Corporation will assume certain
indemnification obligations to Chevron hereunder as the successor in interest to
NGC after the Combination and that such obligations have been negotiated on the
Surviving Corporation's behalf by NGC to provide recourse to Chevron for
breaches of representations, warranties and agreements of NGC in lieu of Chevron
having such recourse against the stockholders of NGC as of immediately prior to
the Closing. Newco, NGC and Chevron agree (i) that the principles of reciprocal
indemnification under this Agreement are fair to the stockholders of NGC and to
Chevron, and, will be fair, upon consummation of the Combination to the
stockholders of the Surviving Corporation and (ii) that the Surviving
Corporation should be charged to administer such indemnities impartially.
Accordingly NGC and Newco, on their own behalf and as predecessors in interest
to the Surviving Corporation, agree with Chevron that, from and after the
Closing, the Surviving Corporation shall exercise stewardship of its assets and
affairs without regard to the existence, nature or extent of any indemnity to or
from Chevron arising under this Agreement, and in this regard, the Surviving
Corporation will assume a duty to Chevron that is equal to the duty it owes to
its stockholders as a whole; provided however, that the Surviving Corporation
may make claims against Chevron to the extent permitted under this Agreement.
The Surviving Corporation shall make and keep good records of potential claims
for indemnification to or from Chevron, and provide Chevron with access thereto
at all times. Newco and NGC, on their own behalf and as predecessors in interest
to the Surviving Corporation, further agree with Chevron that neither Newco or
NGC nor the Surviving Corporation (upon consummation of the Combination) will
induce or persuade a third party or Governmental Entity to bring, or disclose or
notify or otherwise bring to the attention of a third party or Governmental
Entity, any claim that any such third party or Governmental Entity may have
against the Surviving Corporation if such claim would be subject to
indemnification by Chevron under this Agreement or the Contribution and
Assumption Agreement, except in instances where contractual obligations or
duties or applicable law require or obligate the Surviving Corporation to make
such disclosure or notification, or, if the Board of Directors of the Surviving
Corporation determines in good faith, for reasons unrelated to the provisions of
this Agreement, that it would be in the best interest of the Surviving
Corporation to do so.

         15.9 ASSUMPTION OF SENIOR NOTES. As promptly as practicable after the
consummation of the Combination, the Surviving Corporation shall take any and
all actions necessary to assume

                                       86

(a) the 6-3/4% Senior Notes of NGC due December 15, 2005, and (b) all
obligations under the Credit Agreement dated as of March 14, 1995 by and among
NGC, The First National Bank of Chicago, individually and as agent, and the
institutions which are parties thereto.

         15.10 REGISTRATION OF CERTAIN SECURITIES. If the issuance of the shares
of Newco Common Stock issued to the PEP Individuals in connection with the
Merger is not registered under the Securities Act pursuant to the registration
statement including the Definitive Information Statement/Prospectus, as soon as
practicable after the Effective Time the Surviving Corporation shall file a
registration statement on the appropriate form to register such shares for
resale under the Securities Act and shall make such other state blue sky filings
as are necessary to register such shares, in each case in accordance with the
Registration Rights Agreement, dated as of October 21, 1994, among NGC (as
successor to Trident Holding), British Gas, NOVA and the PEP Individuals.

                               GENERAL PROVISIONS

         16.1 EFFECT OF DUE DILIGENCE. No investigation by any party to this
Agreement into the business, operations and condition of any other party shall
diminish in any way the effect of any representations or warranties made by such
other party in this Agreement or shall relieve such other party of any of its
obligations under this Agreement. Notwithstanding the foregoing, neither Chevron
nor NGC shall be deemed to be in breach of its representations and warranties
contained herein if and to the extent that the other had actual knowledge on the
date hereof that any such representation or warranty was inaccurate; provided,
however, that such knowledge shall have no effect on any indemnification
obligation hereunder (other than for indemnification for the breach of such
representation or warranty) in the absence of fraud or bad faith. The parties
agree that any item specifically disclosed on any schedule to this Agreement
shall be deemed to be disclosed for all purposes of this Agreement,
notwithstanding the fact that such item was not disclosed on any other schedule
to this Agreement.

         16.2 SUCCESSORS AND ASSIGNS. This Agreement will inure to the benefit
of and be binding upon the parties to this Agreement and their respective
successors and assigns, and no other Person will have any obligations hereunder;

obligations hereunder without the prior written consent of all other parties
hereto.

                        NGC CORPORATION AND CHEVRON SIGN
                          DEFINITIVE MERGER AGREEMENTS

         HOUSTON (May 23, 1996) -- NGC Corporation and Chevron have signed
definitive agreements related to the proposed merger announced by both companies
in January. The merger will combine all of NGC with most of Chevron's Natural
Gas Business Unit and Tulsa-based Warren Petroleum. The new company, which will
retain the NGC name, will be the largest natural gas and natural gas liquids
marketer in North America. The merger is expected to close in the third quarter
of 1996.
         NGC Chairman and Chief Executive Officer Chuck Watson said, "With the
signing of the merger agreement, we have made substantial progress toward
expanding our Energy Store into a superstore that will be North America's
largest multi-commodity resource of energy products and services."
         Chevron Chairman Ken Derr said, "Signing these agreements completes our
negotiations on the proposal we announced in January, and we look forward to
implementing the merger of our midstream operations into an important
growth-oriented business with both U.S. and international opportunities."

                                       -2-

         Chevron will receive approximately 38.6 million new shares of common
stock and approximately 7.8 million shares of participating preferred stock in
the new company, plus approximately $300 million in cash and notes. After the
merger, Chevron and NGC's two current major shareholders, British Gas and NOVA,
would each own approximately 25 percent of the common stock in NGC.
         Upon the merger, Chevron's Warren Petroleum and Natural Gas Business
Unit will be merged with NGC's midstream and energy marketing operations. The
natural gas division of NGC will retain the Natural Gas Clearinghouse name,
while NGC's liquids assets, currently operated under the name Trident NGL, Inc.,
will operate under the name Warren Petroleum. NGC will market virtually all of
Chevron's North American production of natural gas, natural gas liquids and
electricity and will supply natural gas, natural gas liquids and/or electricity
to Chevron's refineries, chemical plants and corporate facilities in North
America.
         The merger is conditioned upon necessary regulatory and other
approvals.
         NGC and Chevron will continue discussions on two separate proposals
that could enhance the merger -- one for creating an integrated Canadian energy
products business; another for managing a major Chevron gas processing facility
in Venice, La.
         NGC Corporation (NYSE:NGL) is a leading gatherer, processor,
transporter and marketer of energy products and services in North America and
the United Kingdom. Through its "Energy Store," NGC offers a multi-commodity
energy-product-and-services resource that provides natural gas, natural gas
liquids, electricity and crude oil. NGC through its affiliates markets an
average of 7 billion cubic feet per day of natural gas sales volumes throughout
North America and the United Kingdom.
         San Francisco-based Chevron Corporation is the sixth largest oil
company (by revenues) in the world and is the largest marketer of refined
petroleum products in the United States; the third largest producer of natural
gas; and, through Warren, a leading processor and marketer of natural gas
liquids in North America.
