1. BASIS OF PRESENTATION
 
     The 1993 Annual Report on Form 10-K for El Paso Natural Gas Company and
subsidiaries includes a summary of significant accounting policies and should be
read in conjunction with this Form 10-Q. As used herein, "Company" refers to El
Paso Natural Gas Company and its subsidiaries and "EPG" refers to El Paso
Natural Gas Company, unless the context otherwise requires. The financial
statements for the periods presented are unaudited, condensed and do not contain
all of the information required by generally accepted accounting principles to
be included in a full set of financial statements. In the opinion of management,
all material adjustments necessary to present fairly the results of operations
for such periods have been included. All such adjustments are of a normal
recurring nature. Results of operations for any interim period are not
necessarily indicative of the results of operations for the entire year.
Financial statements for previous periods include certain reclassifications
which were made to conform to current presentation. Such reclassifications have
no effect on reported net income or stockholders' equity.
 
2. ACQUISITION
 
     On June 1, 1993, the Company acquired from a wholly owned subsidiary of
Enron Corp., that subsidiary's 50 percent interest in Mojave Pipeline Company
("MPC"), a general partnership, for approximately $40 million in cash,
representing the approximate book value of the investment. The acquisition,
which was funded by internally generated cash flow, gives the Company 100
percent ownership of MPC. The acquisition was accounted for using the purchase
method.
 
     The operating results of MPC for the six months ended June 30, 1994 and the
two months ended June 30, 1993, are included in the Consolidated Statement of
Income. The income effect of the Company's previously owned 50 percent equity
interest in MPC for the first four months of 1993 is included in other-net in
the Consolidated Statement of Income.
 
     The following pro forma summary presents the consolidated results of
operations of the Company as if the acquisition had occurred as of January 1,
1993. This pro forma has been prepared for comparative purposes only and does
not purport to be indicative of what may have resulted had the acquisition
occurred as of that date or of results which may occur in the future.

3. RATES AND REGULATORY MATTERS
 
     On January 14, 1994, EPG filed an application with the Federal Energy
Regulatory Commission ("FERC") seeking an order which would terminate, effective
January 1, 1996, certificates applicable to certain gathering and production
area facilities owned by EPG on the basis that such facilities are not subject
to FERC jurisdiction. EPG intends, effective January 1, 1996, to transfer all of
its nonjurisdictional gathering and production area facilities to a wholly owned
subsidiary of EPG, El Paso Field Services Company. The facilities to be
transferred consist of approximately 6,700 miles of various sized pipelines,
compressors with a combined horsepower of 40,600 and various treating and
processing plants.
 
     Several producers and other shippers filed protests and requests for a
formal hearing of the January 14, 1994 application. The primary issues raised in
the protests focus on the extent of competition in EPG's producing basins and
the proper functionalization of its facilities. In response to the producer and
shipper

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
protests, EPG made a filing on March 15, 1994 asserting that the protests raise
issues already settled under EPG's 1993 settlement agreement.
 
     On May 25, 1994, FERC issued a series of orders which clarified their
policy regarding the regulation of gathering facilities. These orders approved
the requests of various pipelines to terminate certificates applicable to
certain of their respective gathering facilities. Although FERC has stated it
will evaluate all applications on a case by case basis, management believes
EPG's January 14, 1994 application will be approved.
 
     EPG's 1993 settlement agreement provided, in part, for the accelerated
recovery of a substantial portion of EPG's investment in its underground storage
facility. The amount to be recovered was approximately $56.7 million plus
interest accruing beginning February 1, 1993 at the FERC allowed rate, which
approximates the prime rate. On March 25, 1994, EPG received a final FERC letter
order approving the recovery of $56.7 million of underground storage facility
costs. This is being recovered by a demand charge mechanism over the period from
October 1, 1993 through December 31, 1996. The amount recovered through June 30,
1994 was $26 million. The outstanding balance at June 30, 1994 and December 31,
1993 was $30 million and $37 million, respectively, of which $12 million is
reflected in the current portion of other regulatory assets for both periods and
$18 million and $25 million, respectively, is included in other regulatory
assets in the Consolidated Balance Sheet.
 
     MPC filed a service and rate design restructuring plan on November 3, 1992,
in compliance with FERC's industry-wide restructuring directives. On March 2,
1993, FERC issued an order essentially approving MPC's compliance filing,
subject to changes, which were made in an amended restructuring plan on March
29, 1993.
 
     Several of MPC's customers filed protests and requests for rehearing of the
March 2, 1993 FERC order. The rehearing requests were denied, and FERC approved
the amended restructuring plan on July 9, 1993, with an effective date of August
1, 1993. On October 15, 1993, FERC issued an order which denied requests for
rehearing of the July 9, 1993 order. Several of MPC's customers have filed
petitions with the United States Court of Appeals for the District of Columbia
Circuit ("Court of Appeals") for review of the March 2, 1993, July 9, 1993 and
October 15, 1993 orders. These petitions are currently pending. The primary
issues on appeal pertain to FERC's requirement that MPC's rates for firm
transportation service be based upon Straight Fixed Variable ("SFV") rate design
rather than Modified Fixed Variable ("MFV") rate design. The application of SFV
rates requires MPC's existing firm shippers to pay a higher proportion of their
total transportation rate in the reservation component of the rate. Such
shippers have contended that FERC's application of SFV rate design to MPC
unlawfully abrogates the rate provisions of MPC's service agreements and
constitutes an unlawful rate increase. Management believes the Court of Appeals
will uphold SFV rates as applied to MPC.
 
     EPG has made buy-out and buy-down payments and recoupable prepayments to
resolve past and future take-or-pay exposure, to terminate and reform gas
purchase contracts, to amend pricing and take provisions of gas purchase
contracts and to settle related litigation. EPG is collecting its buy-out and
buy-down costs under FERC cost recovery procedures. Under FERC procedures,
take-or-pay cost recovery filings may be challenged by pipeline customers on
prudence and certain other grounds.
 
     Several customers claimed that EPG sought to recover an excessive amount
for the value of certain production properties which were transferred to a
producer as part of a 1989 take-or-pay settlement. On March 8, 1993, an initial
decision from the presiding Administrative Law Judge ("ALJ") was rendered which
required EPG to refund to its customers the costs found to be ineligible for
take-or-pay recovery. On June 16, 1994, FERC affirmed the ALJ's initial
decision. As a result, EPG will be required to refund approximately $40 million,
inclusive of interest, to its customers during the third quarter of 1994. EPG
has established reserves for this refund. On July 18, 1994, EPG filed for
rehearing of the June 16, 1994 order.

4. LEGAL PROCEEDINGS
 
     In El Paso Natural Gas Company and Meridian Oil Gathering Inc. v. Amoco
Production Company, filed in Delaware Chancery Court on May 8, 1991, Amoco
Production Company ("Amoco") alleged breaches by EPG and a then affiliated
company, Meridian Oil Gathering Inc. ("MOGI"), of certain gas purchase,
gathering and transportation agreements pertaining to natural gas produced by
Amoco in the San Juan Basin. Amoco alleged breach of "favored nations"
contractual provisions regarding services to be performed by EPG, including
those relating to transportation capacity and rates and sought a court order
requiring specific performance by EPG and MOGI with respect to future
transportation services and an award of monetary damages of an undetermined
amount for alleged past breaches of contract. On March 4, 1992, the Court issued
a Memorandum Opinion which, among other things, denied Amoco's motion for
partial summary judgment and concluded that the Amoco contracts at issue do not
contain the general "favored nations" rights claimed by Amoco. The Court further
concluded that EPG's and MOGI's motions for summary judgment, seeking dismissal
of Amoco's counterclaim against MOGI, should be granted. Conoco Inc. ("Conoco")
asserted claims similar to Amoco's original claims, involving lesser quantities
of gas, in a separate Delaware Chancery Court proceeding filed on December 30,
1991, Conoco Inc. v. El Paso Natural Gas Company. In August 1992, the Amoco and
Conoco cases were consolidated, MOGI was dismissed as a party, and Amoco and
Conoco filed amended pleadings to restate their claims in light of the court's
March 4, 1992 ruling. EPG and Conoco concluded a settlement agreement which
resulted in dismissal of the Conoco claims. Trial of the Amoco claims concluded
on July 15, 1993, and post-trial briefing and oral arguments concluded in early
November, 1993. On March 29, 1994, the Court rendered a decision in favor of
Amoco. As a result of the Court's decision, EPG will be required to refund to
Amoco amounts which at June 30, 1994 were approximately $15 million, plus
interest of $4 million. In connection with the Amoco decision, EPG recorded a
litigation special charge of approximately $19 million in the first quarter of
1994. Additional briefs have been submitted to the court on the issue of
damages, and EPG is awaiting a final order from the trial court. EPG intends to
appeal the Court's decision.
 
     TransAmerican Natural Gas Corporation ("TransAmerican") has filed a
complaint in a Texas state court against various parties, including EPG,
alleging fraud, tortious interference with contractual relationships, economic
duress, civil conspiracy and violation of state antitrust laws. The complaint,
as amended, seeks unspecified actual and exemplary damages. EPG is actively
defending the matter and has initiated collateral proceedings challenging both
the validity of TransAmerican's claims and the jurisdiction of the forum in
which they were filed. No discovery has been commenced pending resolution of
these threshold issues. Based on information available at this time, management
believes that the claims made by TransAmerican have no factual or legal basis
and that the ultimate resolution of this matter will not have a materially
adverse effect on the Company's financial condition.
 
     EPG and FERC Enforcement Section, Office of the General Counsel
("Enforcement"), entered into a settlement agreement resolving all issues in
Enforcement's investigation of EPG's installation of certain delivery taps.
Enforcement asserted that EPG commenced installation of the delivery taps prior
to receiving clearances from the appropriate State Historic Preservation Office
and the United States Fish and Wildlife Service. FERC approved the settlement
agreement on May 13, 1994. In accordance with the agreement, EPG paid total
civil penalties of $160,000 in the second quarter of 1994.
 
     The Company is a named defendant in numerous lawsuits and a named party in
numerous governmental proceedings arising in the ordinary course of business.
While the outcome of such lawsuits or other proceedings against the Company
cannot be predicted with certainty, management does not expect these matters to
have a materially adverse effect on the Company's financial condition.

5. ENVIRONMENTAL
 
     Accruals for environmental compliance costs are established when
environmental assessments and/or remediation are probable and when costs can be
reasonably estimated. As of June 30, 1994, EPG had a reserve of $38 million for
the following environmental contingencies with income statement impact:
 
     1 -- EPG has been conducting remediation of polychlorinated biphenyl
     ("PCB") contamination at certain of its facilities. The majority of the
     required PCB remediation has been completed. Future PCB remediation costs
     are estimated to range between $8 million and $15 million over the next
     four years.
 
     2 -- EPG executed an Administrative Order on Consent with the United States
     Environmental Protection Agency ("EPA") on June 25, 1993 to conduct a
     Remedial Investigation/Feasibility Study ("RI/FS") for a Burlington
     Industries, Inc. ("BI") site located in Statesville, North Carolina, that
     has been identified for cleanup. BI and EPG have entered into an agreement
     to jointly fund the RI/FS for the site. EPG's share of the potential
     remediation costs is estimated to be between $17 million and $20 million
     over a 30 year period.
 
     3 -- On November 2, 1993, in accordance with an EPA order, EPG and Atlantic
     Richfield Company ("ARCO") submitted work plans for remediation of the
     subsurface at the Prewitt Refinery in McKinley County, New Mexico. EPG and
     ARCO have a cost sharing agreement to each pay one-half of any remediation
     costs at this site. EPG's share of the remediation costs is estimated to be
     between $10 million and $20 million over a 30 year period.
 
     4 -- On December 21, 1993, EPA issued EPG a Notice of Liability for the
     Colorado School of Mines Research Institute ("CSMRI") site in Golden,
     Colorado. EPA has determined that the volume of hazardous substances sent
     to the site by EPG represent approximately 2.4% of the total volumes sent
     by all the potentially responsible parties. Based on this percentage, EPG's
     share of the potential remediation costs is estimated to be less than
     $500,000.
 
     5 -- EPG is involved in other environmental assessment and remediation
     activities which include two Comprehensive Environmental Response,
     Compensation and Liability Act of 1980 ("CERCLA") sites (Fountain Inn,
     South Carolina and Odessa, Texas) and one state Superfund site (Etowah,
     Tennessee). EPG has entered into a de minimis administrative order on
     consent with EPA for EPG's share of the environmental remediation costs
     associated with the CERCLA site in Odessa, Texas. In accordance with the
     order, EPG will pay total costs of approximately $32,000. Management
     believes the amount reserved as of June 30, 1994 is sufficient to cover
     these and other small environmental assessments and remediation activities.
 
EPG also has potential expenditures of a capital nature for the following
environmental projects:
 
     1 -- EPG has analyzed the Clean Air Act Amendments of 1990 ("CAAA"), and
     believes that these rules will impact the Company's operations primarily in
     the following areas: (i) potential required reductions in the emissions of
     nitrogen oxides ("NOx") in non-attainment areas; (ii) the requirement for
     air emissions permitting of existing facilities; and (iii) enhanced
     monitoring of air emissions. The Company anticipates capitalizing the
     equipment costs associated with complying with CAAA and estimates that
     approximately $5 million to $27 million will be spent during the 1995
     through 1997 time frame. However, EPA's proposed enhanced monitoring rules,
     when finalized, could potentially impose greater costs to the Company.
 
     2 -- EPG has been conducting remediation of mercury contamination at
     certain facilities and is replacing mercury containing meters with dry flow
     devices. The remaining remediation costs are estimated to be between $8
     million and $13 million. The mercury remediation project is expected to be
     completed by January 1, 1996. EPG will close and retire about 2,500 earthen
     siphon/dehydration pits in the San Juan Basin as recently required by
     certain environmental regulations. EPG estimates costs of approximately
 
                                        7

                          EL PASO NATURAL GAS COMPANY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     $4 million to $10 million to retire these pits. The project is expected to
     be completed by January 1, 1996. The mercury remediation and pit closure
     costs, which are associated with the retirement of equipment, will be
     recorded as adjustments to accumulated depreciation, as permitted by
     regulatory accounting.
 
     The State of Tennessee has asserted a claim that EPG is a liable party
under state environmental laws for clean up costs associated with a site in
Elizabethton, Tennessee. The State and EPA are in the preliminary stages of
investigating the nature and extent of contamination, as well as identifying
other potentially responsible parties. Since testing is in the initial stages,
EPG is unable to estimate its potential share of any remediation costs.
 
     It is possible that new information or future developments could require
the Company to reassess its potential exposure related to environmental matters.
As such information or developments occur, related accrual amounts will be
adjusted accordingly.
 
6. POSTEMPLOYMENT BENEFITS
 
     Effective January 1, 1994, the Company adopted Statement of Financial
Accounting Standards ("SFAS") No. 112, which requires companies to account for
benefits to former or inactive employees after employment but before retirement
(referred to in SFAS No. 112 as "postemployment benefits"). As of June 30, 1994,
the Company's liability for postemployment benefit costs was approximately $8
million. Management expects to seek recovery of these costs through rates and
has recorded a regulatory asset equal to the liability.
 
7. PROPERTY, PLANT AND EQUIPMENT
 
   Property, plant and equipment at June 30, 1994 and December 31, 1993
consisted of the following:

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
FINANCIAL CONDITION AND LIQUIDITY
 
     Net cash provided by operating activities was $119 million for the six
months ended June 30, 1994 compared with $150 million for the same period of
1993. The decrease from the previous period was primarily due to higher tax
payments and lower accruals for regulatory issues offset by net insurance claims
received, collections of EPG's investment in its underground storage facility
and timing of working capital receipts and disbursements.
 
  Acquisition
 
     On June 1, 1993, the Company acquired from a wholly owned subsidiary of
Enron Corp., that subsidiary's 50 percent interest in MPC, a general
partnership, for approximately $40 million in cash, representing the approximate
book value of the investment. The acquisition, which was funded by internally
generated cash flow, gives the Company 100 percent ownership of MPC. The
acquisition was accounted for using the purchase method.
 
     The operating results of MPC for the six months ended June 30, 1994, and
the two months ended June 30, 1993, are included in the Consolidated Statement
of Income. The income effect of the Company's previously owned 50 percent equity
interest in MPC for the first four months of 1993 is included in other-net in
the Consolidated Statement of Income.
 
     The following pro forma summary presents the consolidated results of
operations of the Company as if the acquisition had occurred as of January 1,
1993. This pro forma has been prepared for comparative purposes only and does
not purport to be indicative of what may have resulted had the acquisition
occurred as of that date or of results which may occur in the future.

  Rates and Regulatory Matters
 
     On January 14, 1994, EPG filed an application with FERC seeking an order
which would terminate, effective January 1, 1996, certificates applicable to
certain gathering and production area facilities owned by EPG on the basis that
such facilities are not subject to FERC jurisdiction. EPG intends, effective
January 1, 1996, to transfer all of its nonjurisdictional gathering and
production area facilities to a wholly owned subsidiary of EPG, El Paso Field
Services Company. The facilities to be transferred consist of approximately
6,700 miles of various sized pipelines, compressors with a combined horsepower
of 40,600 and various treating and processing plants.
 
     Several producers and other shippers filed protests and requests for a
formal hearing of the January 14, 1994 application. The primary issues raised in
the protests focus on the extent of competition in EPG's producing basins and
the proper functionalization of its facilities. In response to the producer and
shipper protests, EPG made a filing on March 15, 1994 asserting that the
protests raise issues already settled under EPG's 1993 settlement agreement.
 
     On May 25, 1994, FERC issued a series of orders which clarified their
policy regarding the regulation of gathering facilities. These orders approved
the requests of various pipelines to terminate certificates applicable to
certain of their respective gathering facilities. Although FERC has stated it
will evaluate all applications on a case by case basis, management believes
EPG's January 14, 1994 application will be approved.
 
     EPG's 1993 settlement agreement provided, in part, for the accelerated
recovery of a substantial portion of EPG's investment in its underground storage
facility. The amount to be recovered was approximately $56.7 million plus
interest accruing beginning February 1, 1993 at the FERC allowed rate, which
approximates the prime rate. On March 25, 1994, EPG received a final FERC letter
order approving the recovery of $56.7 million of underground storage facility
costs. This is being recovered by a demand charge mechanism
 
                                        9
<PAGE>   11
 
over the period from October 1, 1993 through December 31, 1996. The amount
recovered through June 30, 1994 was $26 million. The outstanding balance at June
30, 1994 and December 31, 1993 was $30 million and $37 million, respectively, of
which $12 million is reflected in the current portion of other regulatory assets
for both periods and $18 million and $25 million, respectively, is included in
other regulatory assets in the Consolidated Balance Sheet.
 
     MPC filed a service and rate design restructuring plan on November 3, 1992,
in compliance with FERC's industry-wide restructuring directives. On March 2,
1993, FERC issued an order essentially approving MPC's compliance filing,
subject to changes, which were made in an amended restructuring plan on March
29, 1993.
 
     Several of MPC's customers filed protests and requests for rehearing of the
March 2, 1993 FERC order. The rehearing requests were denied, and FERC approved
the amended restructuring plan on July 9, 1993, with an effective date of August
1, 1993. On October 15, 1993, FERC issued an order which denied requests for
rehearing of the July 9, 1993 order. Several of MPC's customers have filed
petitions with the Court of Appeals for review of the March 2, 1993, July 9,
1993 and October 15, 1993 orders. These petitions are currently pending. The
primary issues on appeal pertain to FERC's requirement that MPC's rates for firm
transportation service be based upon SFV rate design rather than MFV rate
design. The application of SFV rates requires MPC's existing firm shippers to
pay a higher proportion of their total transportation rate in the reservation
component of the rate. Such shippers have contended that FERC's application of
SFV rate design to MPC unlawfully abrogates the rate provisions of MPC's service
agreements and constitutes an unlawful rate increase. Management believes the
Court of Appeals will uphold SFV rates as applied to MPC.
 
     EPG has made buy-out and buy-down payments and recoupable prepayments to
resolve past and future take-or-pay exposure, to terminate and reform gas
purchase contracts, to amend pricing and take provisions of gas purchase
contracts and to settle related litigation. EPG is collecting its buy-out and
buy-down costs under FERC cost recovery procedures. Under FERC procedures,
take-or-pay cost recovery filings may be challenged by pipeline customers on
prudence and certain other grounds.
 
     Several customers claimed that EPG sought to recover an excessive amount
for the value of certain production properties which were transferred to a
producer as part of a 1989 take-or-pay settlement. On March 8, 1993, an initial
decision from the presiding ALJ was rendered which required EPG to refund to its
customers the costs found to be ineligible for take-or-pay recovery. On June 16,
1994, FERC affirmed the ALJ's initial decision. As a result, EPG will be
required to refund approximately $40 million, inclusive of interest, to its
customers during the third quarter of 1994. EPG has established reserves for
this refund. On July 18, 1994, EPG filed for rehearing of the June 16, 1994
order.
 
  Gathering and Processing Agreement
 
     On June 27, 1994, EPG and Meridian Oil Production Inc. ("Meridian") entered
into an agreement concerning production from Meridian conventional gas wells
located on 1.5 million acres in the San Juan Basin. Under the terms of the
agreement, which is retroactive to January 1, 1994, Meridian's gas is committed
to flow exclusively through EPG's gathering and processing facilities through
February 29, 2000.
 
  Environmental
 
     Accruals for environmental compliance costs are established when
environmental assessments and/or remediation are probable, and when costs can be
reasonably estimated. As of June 30, 1994, EPG had a reserve of $38 million for
the following environmental contingencies with income statement impact:
 
     1 -- EPG has been conducting remediation of PCB contamination at certain of
     its facilities. The majority of the required PCB remediation has been
     completed. Future PCB remediation costs are estimated to range between $8
     million and $15 million over the next four years.
 
     2 -- EPG executed an Administrative Order on Consent with EPA on June 25,
     1993 to conduct a RI/FS for a BI site located in Statesville, North
     Carolina, that has been identified for cleanup. BI and EPG have entered
     into an agreement to jointly fund the RI/FS for the site. EPG's share of
     the potential remediation costs is estimated to be between $17 million and
     $20 million over a 30 year period.
 
                                       10
<PAGE>   12
 
     3 -- On November 2, 1993, in accordance with an EPA order, EPG and ARCO
     submitted work plans for remediation of the subsurface at the Prewitt
     Refinery in McKinley County, New Mexico. EPG and ARCO have a cost sharing
     agreement to each pay one-half of any remediation costs at this site. EPG's
     share of the remediation costs is estimated to be between $10 million and
     $20 million over a 30 year period.
 
     4 -- On December 21, 1993, EPA issued EPG a Notice of Liability for the
     CSMRI site in Golden, Colorado. EPA has determined that the volume of
     hazardous substances sent to the site by EPG represent approximately 2.4%
     of the total volumes sent by all the potentially responsible parties. Based
     on this percentage, EPG's share of the potential remediation costs is
     estimated to be less than $500,000.
 
     5 -- EPG is involved in other environmental assessment and remediation
     activities which include two CERCLA sites (Fountain Inn, South Carolina and
     Odessa, Texas) and one state Superfund site (Etowah, Tennessee). EPG has
     entered into a de minimis administrative order on consent with EPA for
     EPG's share of the environmental remediation costs associated with the
     CERCLA site in Odessa, Texas. In accordance with the order, EPG will pay
     total costs of approximately $32,000. Management believes the amount
     reserved as of June 30, 1994 is sufficient to cover these and other small
     environmental assessments and remediation activities.
 
EPG also has potential expenditures, of a capital nature, for the following
environmental projects:
 
     1 -- EPG has analyzed CAAA, and believes that these rules will impact the
     Company's operations primarily in the following areas: (i) potential
     required reductions in the emissions of NOx in non-attainment areas; (ii)
     the requirement for air emissions permitting of existing facilities; and
     (iii) enhanced monitoring of air emissions. The Company anticipates
     capitalizing the equipment costs associated with complying with CAAA and
     estimates that approximately $5 million to $27 million will be spent during
     the 1995 through 1997 time frame. However, EPA's proposed enhanced
     monitoring rules, when finalized, could potentially impose greater costs to
     the Company.
 
     2 -- EPG has been conducting remediation of mercury contamination at
     certain facilities and is replacing mercury containing meters with dry flow
     devices. The remaining remediation costs are estimated to be between $8
     million and $13 million. The mercury remediation project is expected to be
     completed by January 1, 1996. EPG will close and retire about 2,500 earthen
     siphon/dehydration pits in the San Juan Basin as recently required by
     certain environmental regulations. EPG estimates costs of approximately $4
     million to $10 million to retire these pits. The project is expected to be
     completed by January 1, 1996. The mercury remediation and pit closure
     costs, which are associated with the retirement of equipment, will be
     recorded as adjustments to accumulated depreciation, as permitted by
     regulatory accounting.
 
     The State of Tennessee has asserted a claim that EPG is a liable party
under state environmental laws for clean up costs associated with a site in
Elizabethton, Tennessee. The State and EPA are in the preliminary stages of
investigating the nature and extent of contamination, as well as identifying
other potentially responsible parties. Since testing is in the initial stages,
EPG is unable to estimate its potential share of any remediation costs.
 
     It is possible that new information or future developments could require
the Company to reassess its potential exposure related to environmental matters.
As such information or developments occur, related accrual amounts will be
adjusted accordingly.
 
  Other
 
     On August 10, 1994, EPG established with a group of banks a revolving
credit facility of $400 million which expires in five years. This credit
facility replaced an existing $300 million revolving credit facility.
 
     In January 1993, EPG experienced flood damage to its pipeline system in the
Gila, Arizona area due to heavy rain. Since that time, EPG has been incurring
costs for repairs and expects these costs to be reimbursed through its property
insurance policies. As of June 30, 1994, EPG has received approximately $10
million of insurance reimbursements and expects to be reimbursed for the
remaining costs once all repairs have been completed.

     EPG's largest single contract for interstate capacity to California is its
1,450 million cubic feet per day ("MMcf/d")contract with Southern California Gas
Company ("SoCal"), which has a primary term ending August 31, 2006. Pursuant to
this contract, SoCal has exercised its option to relinquish 300 MMcf/d of
capacity during the first quarter of 1996. EPG is working to offset this future
reduction in capacity commitments through new contracts with various natural gas
users.

     On July 15, 1994, the Board of Directors declared a quarterly dividend of
$0.3025 per share on EPG's common stock, payable on October 3, 1994, to
shareholders of record on September 9, 1994.
 
CAPITAL EXPENDITURES
 
     The Company's planned capital expenditures for 1994 of $210 million are
primarily for maintenance of business, system expansion and system enhancement.
Capital expenditures for the six months ended June 30, 1994 were $41 million
compared to $54 million for the same period of 1993.
 
     On July 7, 1992, EPG filed an application with FERC, which was amended on
November 27, 1992, to expand the delivery capacity of its system in the vicinity
of Yuma, Arizona and, through an extension of its system south to San Luis Rio
Colorado, Sonora, Mexico. The proposed expansion would provide shippers the
opportunity to deliver natural gas to Mexican markets in northern Baja
California via new pipeline capacity of 348 MMcf/d. The project cost was
approximately $71 million. On June 22, 1994, EPG withdrew the July 7, 1992
application, citing delays in the conversion to natural gas and expansion of the
existing Benito Juarez Power Plant in Rosarito, Baja California Norte, Mexico.
In withdrawing the pending application, EPG emphasized that it is not abandoning
the project. At such time as the Comision Federal de Electricidad, the Mexican
government-owned utility, proceeds with its plans for the Benito Juarez Power
Plant, EPG may refile its application.
 
     EPG is a member of a five-company consortium that plans to build the
proposed Samalayuca II Power Plant near Ciudad Juarez, Mexico. On December 17,
1992, an award for construction was granted to the consortium by the Comision
Federal de Electricidad. On March 16, 1993, EPG filed an application with FERC
to expand its system in order to provide natural gas service to the proposed
Samalayuca II Power Plant and to an existing power plant in the same location.
The proposed expansion would provide an additional 300 MMcf/d of capacity at a
cost of approximately $57 million. On November 29, 1993, FERC issued an order
which approved the proposed border crossing facility south of Clint, Texas that
would connect EPG's facilities with facilities in Mexico. FERC deferred action
on the remainder of the March 16, 1993 filing until EPG demonstrates that it has
long-term executed contracts or binding precedent agreements for a substantial
amount of the firm capacity of the proposed facilities.
 
     On December 29, 1993, Pacific Gas & Electric Company ("PG&E"), the
California Public Utilities Commission ("CPUC") and SoCal jointly filed a motion
with FERC seeking clarification or rehearing of the November 29, 1993 FERC order
on the Samalayuca II Power Plant project discussed above.
 
     On April 1, 1994, EPG filed an application with FERC for a certificate of
public convenience and necessity to build a 98 mile pipeline to parallel and
loop its existing Havasu Crossover Line. The proposed pipeline would allow for
the transfer of 468 MMcf/d of San Juan Basin gas to EPG's south system and would
enhance EPG's overall system flexibility to meet market demands. The project is
expected to cost approximately $62 million. At the request of several of EPG's
customers, FERC held a technical conference on August 11, 1994 with respect to
the April 1, 1994 application.
 
                                       12
<PAGE>   14
 
     On June 1, 1994, EPG filed an application with FERC for a certificate of
public convenience and necessity to expand its existing system in the San Juan
Basin by approximately 300 MMcf/d at a cost of about $26 million. The proposed
expansion would accommodate increased volumes and provide markets with enhanced
access to San Juan Basin gas supplies. FERC held a technical conference to
address the June 1, 1994 application on August 11, 1994.
 
     The Company plans to construct a new cryogenic natural gas liquids
extraction plant in the San Juan Basin. The plant will process 400 MMcf/d and
will increase the Company's processing capability in the San Juan Basin to 950
MMcf/d. The project is expected to cost approximately $75 million and is
anticipated to be in service by the second quarter of 1996.
 
     On March 17, 1993, MPC filed an application, which was amended on November
8, 1993 and April 18, 1994, for a certificate of public convenience and
necessity to build and operate a 475 MMcf/d expansion of its existing system.
The proposed expansion will extend from MPC's existing east lateral, located
near Bakersfield, California, approximately 352 miles northward to the vicinity
of Sacramento and the Bay Area near San Francisco. The expansion will also
include 56 miles of looping of the existing pipeline along with 207 miles of
laterals. The estimated cost of the entire expansion is approximately $500
million. MPC expects to receive its FERC certificate in 1994. Receipt of an
acceptable FERC certificate within this time frame would allow the expansion to
be put into service by mid-1996.
 
     On December 16, 1993, FERC held a public conference to examine a
jurisdictional question raised by CPUC and PG&E regarding MPC's proposed
expansion. The primary issue was whether FERC or CPUC should have jurisdiction
over the expansion. Written comments were filed by interested parties on January
10, 1994. On February 15, 1994, FERC issued an order determining that it has
exclusive jurisdiction over MPC and its proposed expansion. On March 17, 1994,
CPUC, PG&E and other parties filed for rehearing or clarification of FERC's
February 15, 1994 order.
 
     The capital projects discussed above are expected to be financed through
internally generated funds and short-term and long-term borrowings.
 
RESULTS OF OPERATIONS
 
  Second Quarter 1994 Compared to Second Quarter 1993
 
     Operating revenues for the second quarter ended June 30, 1994 were $10
million lower than for the same period of 1993. New system rates that became
effective January 1, 1994 resulted in lower reservation and lower transportation
revenues which decreased operating revenues by $15 million and $5 million,
respectively. Lower gas sales volumes, gas sales rates and the 1993 sale of gas
in storage decreased operating revenues by $9 million, $4 million and $3
million, respectively. The decrease due to the 1993 sale of gas in storage was
offset in operating charges. Lower accruals for regulatory issues, higher
production area rates and the consolidation of MPC offset the decrease in
operating revenues by $15 million, $6 million and $5 million, respectively.
 
     Operating charges were $12 million lower for the second quarter ended June
30, 1994 than for the same period of 1993. Lower gas sales volumes and the 1993
sale of gas in storage contributed $9 million and $3 million, respectively, to
the decrease in operating charges. The decrease due to the 1993 sale of gas in
storage was offset in operating revenues. Operation and maintenance expense
decreased $3 million due primarily to lower stock related costs and adjustments
to the take-or-pay undercollections accrual. Offsetting the decrease were
additional operation and maintenance costs due to the consolidation of MPC.
 
     EPG's mainline throughput for the quarter ended June 30, 1994 was 313
billion cubic feet ("Bcf") compared to 290 Bcf for the same period of 1993.
Deliveries to the California market increased in the 1994 period due to an
increase in utility electric generation demand, which resulted from a decrease
in the availability of hydroelectric power. Field transportation volumes of 118
Bcf for the second quarter ended June 30, 1994 were relatively unchanged
compared to the second quarter ended June 30, 1993 volumes of 119 Bcf.
 
                                       13
<PAGE>   15
 
     Other-net was $5 million higher for the quarter ended June 30, 1994 than
for the same period of 1993. Contributing to the 1994 increase were lower
accruals for environmental cleanup issues, a note receivable write-off in 1993
and a loss on the disposition of property in 1993. Lower allowance for funds
used during construction ("AFUDC") offset the increase in other-net by $2
million.
 
  Six Months Ended 1994 Compared to Six Months Ended 1993
 
     Operating revenues for the six months ended June 30, 1994 were $1 million
higher than for the same period of 1993. The consolidation of MPC, lower
accruals for regulatory issues and higher production area rates contributed $16
million, $25 million and $9 million, respectively, to the increase in operating
revenues. New system rates that became effective January 1, 1994 resulted in
lower reservation and lower transportation revenues that offset the increase in
operating revenues by $14 million and $18 million, respectively. Additionally,
lower gas sales volumes, lower transportation volumes and the 1993 sale of gas
in storage contributed $9 million, $2 million and $3 million, respectively, to
the decrease in operating revenues. The decrease due to the 1993 sale of gas in
storage was offset in operating charges.
 
     Operating charges were $14 million higher for the six months ended June 30,
1994 than for the same period of 1993. The increase in operating charges was due
to a litigation special charge of $15 million in connection with the Amoco
decision. Higher average cost of gas contributed $17 million to the increase. In
addition, depreciation expense increased by $3 million, primarily due to the
consolidation of MPC. Lower gas sales volumes and the 1993 sale of gas in
storage offset the increase in operating charges by $8 million and $3 million,
respectively. The decrease due to the 1993 sale of gas in storage was offset in
operating revenues. Additionally, operation and maintenance expense decreased $7
million primarily due to lower stock related costs, lower take-or-pay absorption
expense, lower Gas Research Institute expense and adjustments to the take-or-pay
undercollections accrual. The consolidation of MPC partially offset the decrease
in operation and maintenance expense.
 
     EPG's mainline throughput for the six months ended June 30, 1994 was 626
Bcf compared to 654 Bcf for the same period of 1993. Deliveries to the
California market decreased due to higher storage withdrawals and increased
competition partially offset by an increase in utility electric generation
demand, which resulted from a decrease in the availability of hydroelectric
power. The decrease was also offset by increased deliveries to off-system
markets. Field transportation volumes of 237 Bcf for the six months ended June
30, 1994 were relatively unchanged compared to 234 Bcf for the same period ended
June 30, 1993.
 
     Interest and debt expense for the six months ended June 30, 1994 was $4
million higher than for the same period of 1993 due primarily to the
consolidation of MPC.
 
     Other-net was $9 million higher for the six months ended June 30, 1994 than
for the same period of 1993. Contributing to the 1994 increase were $14 million
related to the recovery of EPG's investment in its underground storage facility
and lower accruals for environmental cleanup issues. The increase was offset by
interest expense related to the special charge for litigation in connection with
the Amoco decision of approximately $4 million and a reduction in partnership
earnings due to the consolidation of MPC. Additionally, a decrease in AFUDC
offset the increase in other-net by $3 million.

     Effective January 1, 1994, the Company adopted SFAS No. 112, which requires
companies to account for postemployment benefits. As of June 30, 1994, the
Company's liability for postemployment benefit costs was approximately $8
million. Management expects to seek recovery of these costs through rates and
has recorded a regulatory asset equal to the liability.

        Continuous Odd-Lot Stock Sales Program
 
        EPG has made available a Continuous Odd-Lot Stock Sales Program
        ("Program") in which shareholders of EPG owning beneficially fewer than
        100 shares of EPG's common stock ("Odd-lot Holders") are offered a
        convenient method of disposing of all their shares without incurring the
        customary brokerage costs associated with the sale of an odd-lot. Only
        Odd-lot Holders are eligible to participate in the Program. The Program
        is strictly voluntary and no Odd-lot Holder is obligated to sell
        pursuant to the Program. A brochure and related materials describing the
        Program were sent to Odd-lot Holders in February 1994. The Program
        currently does not have a termination date, but EPG may suspend the
        Program at any time. Inquiries regarding the Program should be directed
        to The First National Bank of Boston, the agent for the Program, at
        1-800-736-3001.

                                   ARTICLE II

                       AMOUNTS AND TERMS OF THE ADVANCES

                 SECTION 2.1  The Revolving Credit Advances.  Each Lender
severally agrees, on the terms and conditions hereinafter set forth, to make
revolving credit advances ("Revolving Credit Advances") to the Borrowers or any
one or more of them from time to time on any Business Day during the period
from the date hereof to and including the Termination Date in an aggregate
amount not to exceed at any time outstanding the amount of such Lender's
Commitment; provided that the aggregate amount of the Advances outstanding
shall not at any time exceed the aggregate amount of the Commitments.  Each
Borrowing shall be in an aggregate amount of $5,000,000 in the case of a
Borrowing comprised of Base Rate Advances and $20,000,000 in the case of a
Borrowing comprised of Eurodollar Rate Advances, or, in each case, an integral
multiple of $1,000,000 in excess thereof (or, in the case of a Borrowing of
Base Rate Advances, the aggregate unused Commitments, if less) and shall
consist of Revolving Credit Advances of the same Type made on the same day by
the Lenders ratably according to their respective Commitments.  Within the
limits of each Lender's Commitment, any Borrower may make more than one
Borrowing on any Business Day and may borrow, repay pursuant to Section 2.10 or
prepay pursuant to Section 2.15, and reborrow under this Section 2.1.

                 SECTION 2.2  Revolving Credit Notes.  The Revolving Credit
Advances to each Borrower made by each Lender shall be evidenced by a
promissory note of such Borrower, substantially in the form of Exhibit A, with
appropriate insertions as to maker, payee, date and principal amount (a
"Revolving Credit Note"), payable to the order of such Lender and in a
principal amount equal to the lesser of (a) the amount of the initial
Commitment of such Lender and (b) the aggregate unpaid principal amount of all
Revolving Credit Advances made to such Borrower by such Lender.  Each Lender is
hereby authorized to, and prior to any transfer thereof shall, record the date,
Type and amount of each Revolving Credit Advance made by such Lender, each
continuation thereof, each conversion of all or a portion thereof to another
Type, the date and amount of each payment or prepayment of principal thereof
and, in the case of Eurodollar Rate Advances, the length of each Interest
Period with respect thereto, on the schedule annexed to and constituting a part
of its Revolving Credit Note, and any such recordation shall constitute prima
facie evidence of the accuracy of the information so recorded; provided,
however, that the failure to make any such recordation shall not affect the
obligations of such Borrower hereunder or any Revolving Credit Note.  Each
Revolving Credit Note shall (i) be dated (A) in the case of the Company, the
Closing Date or (B) in each other case, the date the applicable Subsidiary
Borrower became a Borrower hereunder, (ii) be stated to mature on the
Termination Date and (iii) provide for the payment of interest in accordance
with this Agreement.

                 SECTION 2.3  Making the Revolving Credit Advances.  (a)  Each
Borrowing of Revolving Credit Advances shall be made on notice by the Company
to the Administrative Agent (a "Notice of Borrowing") received by the
Administrative Agent, (i) in the case of a proposed Borrowing comprised of Base
Rate Advances, not later than 10:00 A.M. (New York City time) on the Business
Day of such proposed Borrowing and (ii) in the case of a proposed Borrowing
comprised of Eurodollar Rate Advances, not later than 12:00 noon (New York City
time) on the third Business Day prior to the date of such proposed Borrowing.
Each Notice of Borrowing shall be by telecopy or telephone (and if by
telephone, confirmed promptly by telecopier), in substantially the form of
Exhibit B hereto, specifying therein the requested (A) Borrower, (B) date of
such Borrowing, (C) Type of Revolving Credit Advances comprising such
Borrowing, (D) aggregate amount of such Borrowing, and (E) in the case of a
Borrowing comprised of Eurodollar Rate Advances, the initial Interest Period
for each such Advance.  Each Lender shall, before 1:00 P.M. (New York City
time) on the date of such Borrowing, make available to the Administrative Agent
at its address at 270 Park Avenue, New York, New York, 10017, Reference:  El
Paso Natural Gas Company, or at such other address designated by notice from
the Administrative Agent to the Lenders pursuant to Section 9.2, in same day
funds, such Lender's ratable portion of such Borrowing.  Immediately after the
Administrative Agent's receipt of such funds and upon fulfillment of the
applicable conditions set forth in Article III, the Administrative Agent will
make such funds available to the applicable Borrower at Chemical, 270 Park
Avenue, New York, New York, 10017, Account No. 323291503, Reference:  El Paso
Natural Gas Company, or at such other account of the applicable Borrower
maintained by the Administrative Agent (or any successor Administrative Agent)
designated by the applicable Borrower and agreed to by the Administrative Agent
(or such successor Administrative Agent), in same day funds.

                 (b)  Each Notice of Borrowing shall be irrevocable and binding
on the applicable Borrower.  In the case of any Borrowing which the related
Notice of Borrowing specified is to be comprised of Eurodollar Rate Advances,
if such Advances are not made as a result of any failure to fulfill on or
before the date specified for such Borrowing the applicable conditions set
forth in Article III, the applicable Borrower shall indemnify each Lender
against any loss, cost or expense incurred by such Lender as a result of such
failure, including, without limitation, any loss, cost or expense incurred by
reason of the liquidation or reemployment of deposits or other funds acquired
by such Lender to fund the Advance to be made by such Lender as part of such
Borrowing.

                 (c)  Unless the Administrative Agent shall have received
notice from a Lender prior to the date of any Borrowing that such Lender will
not make available to the Administrative Agent such Lender's ratable portion of
such Borrowing, the Administrative Agent may assume that such Lender has made
such
<PAGE>   21
                                                                              17



portion available to the Administrative Agent on the date of such Borrowing in
accordance with subsection (a) of this Section 2.2 and the Administrative Agent
may, in reliance upon such assumption, make available to the applicable
Borrower on such date a corresponding amount.  If and to the extent such Lender
shall not have so made such ratable portion available to the Administrative
Agent, such Lender and the applicable Borrower severally agree to repay to the
Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the applicable Borrower until the date such amount is repaid to the
Administrative Agent, at the Effective Federal Funds Rate for such day.  If
such Lender shall repay to the Administrative Agent such corresponding amount,
such amount so repaid shall constitute such Lender's Advance to the applicable
Borrower as part of such Borrowing for purposes of this Agreement.

                 (d)  The failure of any Lender to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Advance on the date of such
Borrowing, but no Lender shall be responsible for the failure of any other
Lender to make the Advance to be made by such other Lender on the date of any
Borrowing.

                 SECTION 2.4  CAF Advances.  Subject to the terms and
conditions of this Agreement, the Borrowers or any one or more of them may
borrow CAF Advances from time to time during the CAF Advance Availability
Period on any Business Day.  The Company shall, in consultation with the CAF
Advance Agent, designate Lenders from time to time as CAF Advance Lenders by
written notice to the CAF Advance Agent.  The CAF Advance Agent shall transmit
each such notice of designation promptly to each designated CAF Advance Lender.
CAF Advances shall be borrowed in amounts such that the aggregate amount of
Advances outstanding at any time shall not exceed the aggregate amount of the
Commitments at such time.  Any CAF Advance Lender may make CAF Advances in
amounts which, individually and together with the aggregate amount of other
Advances of such CAF Advance Lender, exceed such CAF Advance Lender's
Commitment, and such CAF Advance Lender's CAF Advances shall not be deemed to
utilize such CAF Advance Lender's Commitment.  Within the limits and on the
conditions hereinafter set forth with respect to CAF Advances, the Borrowers
from time to time may borrow, repay and reborrow CAF Advances.

                 SECTION 2.5  Procedure for CAF Advance Borrowings.  (a)  A
Borrower shall request CAF Advances by delivering a CAF Advance Request to the
CAF Advance Agent, not later than 12:00 Noon (New York City time) four Business
Days prior to the date of the proposed Borrowing (in the case of a LIBO Rate
CAF Advance Request), and not later than 10:00 A.M. (New York City time) one
Business Day prior to the date of the proposed Borrowing (in the case of a
Fixed Rate CAF Advance Request).  Each CAF Advance Request may solicit bids for

                                                                              18



principal amount of $10,000,000 or an integral multiple of $1,000,000 in excess
thereof and having not more than three alternative maturity dates.  The
maturity date for each CAF Advance shall be not less than 14 days nor more than
180 days after the date of the Borrowing therefor (and in any event shall be
not later than the Stated Termination Date); provided that each LIBO Rate CAF
Advance shall mature one, two, three or six months after the date of the
Borrowing therefor.  The CAF Advance Agent shall notify each CAF Advance Lender
promptly by telecopy of the contents of each CAF Advance Request received by
the CAF Advance Agent.

                 (b)  In the case of a LIBO Rate CAF Advance Request, upon
receipt of notice from the CAF Advance Agent of the contents of such CAF
Advance Request, each CAF Advance Lender may elect, in its sole discretion, to
offer irrevocably to make one or more CAF Advances at the Applicable LIBO Rate
plus (or minus) a margin determined by such CAF Advance Lender in its sole
discretion for each such CAF Advance.  Any such irrevocable offer shall be made
by delivering a CAF Advance Offer to the CAF Advance Agent, before 10:30 A.M.
(New York City time) on the day that is three Business Days before the date of
the proposed Borrowing, setting forth:

                      (i)   the maximum amount of CAF Advances for each
         maturity date and the aggregate maximum amount of CAF Advances for all
         maturity dates which such CAF Advance Lender would be willing to make
         (which amounts may, subject to Section 2.4, exceed such CAF Advance
         Lender's Commitment); and

                      (ii)  the margin above or below the Applicable LIBO Rate
         at which such CAF Advance Lender is willing to make each such CAF
         Advance.

The CAF Advance Agent shall advise the Company before 11:00 A.M. (New York City
time) on the date which is three Business Days before the proposed date of the
Borrowing of the contents of each such CAF Advance Offer received by it.  If
the CAF Advance Agent, in its capacity as a CAF Advance Lender, shall elect, in
its sole discretion, to make any such CAF Advance Offer, it shall advise the
Company of the contents of its CAF Advance Offer before 10:15 A.M. (New York
City time) on the date which is three Business Days before the proposed date of
the Borrowing.

                 (c)  In the case of a Fixed Rate CAF Advance Request, upon
receipt of notice from the CAF Advance Agent of the contents of such CAF
Advance Request, each CAF Advance Lender may elect, in its sole discretion, to
offer irrevocably to make one or more CAF Advances at a rate of interest
determined by such CAF Advance Lender in its sole discretion for each such CAF
Advance.  Any such irrevocable offer shall be made by delivering a CAF Advance
Offer to the CAF Advance Agent before 9:30 A.M. (New York City time) on the
proposed date of the Borrowing, setting forth:
<PAGE>   23
                                                                              19




                      (i)   the maximum amount of CAF Advances for each
         maturity date, and the aggregate maximum amount for all maturity
         dates, which such CAF Advance Lender would be willing to make (which
         amounts may, subject to Section 2.4, exceed such CAF Advance Lender's
         Commitment); and

                      (ii)  the rate of interest at which such CAF Advance
         Lender is willing to make each such CAF Advance.

The CAF Advance Agent shall advise the Company before 10:00 A.M. (New York City
time) on the proposed date of the Borrowing of the contents of each such CAF
Advance Offer received by it.  If the CAF Advance Agent, in its capacity as a
CAF Advance Lender, shall elect, in its sole discretion, to make any such CAF
Advance Offer, it shall advise the Company of the contents of its CAF Advance
Offer before 9:15 A.M. (New York City time) on the proposed date of the
Borrowing.

                 (d)  Before 11:30 A.M. (New York City time) three Business
Days before the proposed date of the Borrowing (in the case of CAF Advances
requested by a LIBO Rate CAF Advance Request) and before 10:30 A.M. (New York
City time) on the proposed date of the Borrowing (in the case of CAF Advances
requested by a Fixed Rate CAF Advance Request), the Company, in its absolute
discretion, shall:

                      (i)   cancel such CAF Advance Request by giving the CAF 
         Advance Agent telephone notice to that effect, or

                      (ii)  by giving telephone notice to the CAF Advance Agent
         (immediately confirmed by delivery to the CAF Advance Agent of a CAF
         Advance Confirmation in writing or by telecopy) (A) subject to the
         provisions of Section 2.5(e), accept one or more of the offers made by
         any CAF Advance Lender or CAF Advance Lenders pursuant to Section
         2.5(b) or Section 2.5(c), as the case may be, of the amount of CAF
         Advances for each relevant maturity date and (B) reject any remaining
         offers made by CAF Advance Lenders pursuant to Section 2.5(b) or
         Section 2.5(c), as the case may be.

                 (e)  The Company's acceptance of CAF Advances in response to
any CAF Advance Request shall be subject to the following limitations:

                      (i)   the amount of CAF Advances accepted for each
         maturity date specified by any CAF Advance Lender in its CAF Advance
         Offer shall not exceed the maximum amount for such maturity date
         specified in such CAF Advance Offer;

                      (ii)  the aggregate amount of CAF Advances accepted for
         all maturity dates specified by any CAF Advance Lender in its CAF
         Advance Offer shall not exceed the aggregate maximum amount specified
         in such CAF Advance Offer for all such maturity dates;
<PAGE>   24
                                                                              20




                    (iii)   the Company may not accept offers for CAF Advances
         for any maturity date in an aggregate principal amount in excess of
         the maximum principal amount requested in the related CAF Advance
         Request; and

                      (iv)  if the Company accepts any of such offers, it must
         accept offers based solely upon pricing for such relevant maturity
         date and upon no other criteria whatsoever and if two or more CAF
         Advance Lenders submit offers for any maturity date at identical
         pricing and the Company accepts any of such offers but does not wish
         to (or by reason of the limitations set forth in Section 2.4 or in
         Section 2.5(e)(iii), cannot) borrow the total amount offered by such
         CAF Advance Lenders with such identical pricing, the Company shall
         accept offers from all of such CAF Advance Lenders in amounts
         allocated among them pro rata according to the amounts offered by such
         CAF Advance Lenders (or as nearly pro rata as shall be practicable
         after giving effect to the requirement that CAF Advances made by a CAF
         Advance Lender on a date of the Borrowing for each relevant maturity
         date shall be in a principal amount of $5,000,000 or an integral
         multiple of $1,000,000 in excess thereof; provided that if the number
         of CAF Advance Lenders that submit offers for any maturity date at
         identical pricing is such that, after the Company accepts such offers
         pro rata in accordance with the foregoing, the CAF Advance to be made
         by such CAF Advance Lenders would be less than $5,000,000 principal
         amount, the number of such CAF Advance Lenders shall be reduced by the
         CAF Advance Agent by lot until the CAF Advances to be made by such
         remaining CAF Advance Lenders would be in a principal amount of
         $5,000,000 or an integral multiple of $1,000,000 in excess thereof).

                 (f)  If the Company notifies the CAF Advance Agent that a CAF
Advance Request is cancelled pursuant to Section 2.5(d)(i), the CAF Advance
Agent shall give prompt telephone notice thereof to the CAF Advance Lenders.

                 (g)  If the Company accepts pursuant to Section 2.5(d)(ii) one
or more of the offers made by any CAF Advance Lender or CAF Advance Lenders,
the CAF Advance Agent promptly shall notify each CAF Advance Lender which has
made such a CAF Advance Offer of (i) the aggregate amount of such CAF Advances
to be made on such Borrowing Date for each maturity date and (ii) the
acceptance or rejection of any offers to make such CAF Advances made by such
CAF Advance Lender.  Before 1:00 P.M. (New York City time) on the date of the
Borrowing specified in the applicable CAF Advance Request, each CAF Advance
Lender whose CAF Advance Offer has been accepted shall make available to the
Administrative Agent at its office set forth in Section 9.2 the amount of CAF
Advances to be made by such CAF Advance Lender, in same day funds.  The
Administrative Agent will make such funds available to the applicable Borrower
as soon as practicable on such date at the Administrative Agent's aforesaid
address.  As

                                                                              21



soon as practicable after each Borrowing Date, the CAF Advance Agent shall
notify each Lender of the aggregate amount of CAF Advances advanced on such
Borrowing Date and the respective maturity dates thereof.

                 (h)  The failure of any CAF Advance Lender to make the CAF
Advance to be made by it as part of any Borrowing shall not relieve any other
Lender of its obligation, if any, hereunder to make its CAF Advance on the date
of such Borrowing, but no CAF Lender shall be responsible for the failure of
any other CAF Advance Lender to make the CAF Advance to be made by such CAF
Advance Lender on the date of any Borrowing.

                 SECTION 2.6  CAF Advance Payments.  (a)  The applicable
Borrower shall repay to the Administrative Agent, for the account of each CAF
Advance Lender which has made a CAF Advance to it, on the applicable CAF
Advance Maturity Date the then unpaid principal amount of such CAF Advance.
The Borrowers shall not have the right to prepay any principal amount of any
CAF Advance.

                 (b)  The applicable Borrower shall pay interest on the unpaid
principal amount of each CAF Advance to it from the date of the Borrowing to
the applicable CAF Advance Maturity Date at the rate of interest specified in
the CAF Advance Offer accepted by the applicable Borrower in connection with
such CAF Advance (calculated on the basis of a 360-day year for actual days
elapsed), payable on each applicable CAF Advance Interest Payment Date.

                 (c)  If all or a portion of the principal amount of any CAF
Advance shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), such overdue principal amount shall, without
limiting any rights of any Lender under this Agreement, bear interest from the
date on which such payment was due at a rate per annum which is 1% above the
rate which would otherwise be applicable pursuant to the CAF Advance Note
evidencing such CAF Advance until the stated maturity date of such CAF Advance,
and for each day thereafter at a rate per annum which is 2% above the Base
Rate, in each case until paid in full (as well after as before judgment).
Interest accruing pursuant to this paragraph (c) shall be payable from time to
time on demand.

                 SECTION 2.7  CAF Advance Notes.  The CAF Advances made by each
CAF Advance Lender to each Borrower shall be evidenced by a promissory note of
such Borrower, substantially in the form of Exhibit C with appropriate
insertions (a "CAF Advance Note"), payable to the order of such CAF Advance
Lender and representing the obligation of such Borrower to pay the unpaid
principal amount of all CAF Advances made to it by such CAF Advance Lender,
with interest on the unpaid principal amount from time to time outstanding of
each CAF Advance evidenced thereby as prescribed in Section 2.6(b).  Each CAF
Advance Lender is hereby authorized to, and prior to any transfer thereof
shall, record the date and

                                                                              22



amount of each CAF Advance made to it by such CAF Advance Lender, the maturity
date thereof, the date and amount of each payment of principal thereof and the
interest rate with respect thereto on the schedule attached to and constituting
part of its CAF Advance Note, and any such recordation shall constitute prima
facie evidence of the accuracy of the information so recorded; provided,
however, that the failure to make any such recordation shall not affect the
obligations of such Borrower hereunder or under any CAF Advance Note.  Each CAF
Advance Note shall be dated (a) in the case of the Company, the Closing Date or
(b) in each other case, the date the applicable Subsidiary Borrower became a
Borrower hereunder, and each CAF Advance evidenced thereby shall bear interest
for the period from and including the Borrowing Date of such CAF Advance on the
unpaid principal amount thereof from time to time outstanding at the applicable
rate per annum determined as provided in, and such interest shall be payable as
specified in, Section 2.6(b).

                 SECTION 2.8  Fees.  (a)  The Company agrees to pay to the
Administrative Agent for the account of each Lender a facility fee for the
period from and including the date hereof to the Termination Date, computed at
a variable rate on the average daily amount of the Commitment of such Lender
during the period for which payment is made, which rate will vary according to
the S&P Bond Rating and the Moody's Bond Rating as follows:

provided that if the ratings of such rating agencies do not fall within the
same Level, the rate applicable to such day will be the lower facility fee rate
and provided, further, that in the event a rating is not available from either
rating agency, such rating agency will be deemed to have assigned its lowest
rating.  Such facility fees shall be payable quarterly in arrears on the last
day of each March, June, September and December and on the Termination Date or
such earlier date on which the Commitments shall terminate as provided herein,
commencing on the first of such dates to occur after the date hereof.

                 (b)      The Company agrees to pay to the Administrative Agent
and the CAF Advance Agent the fees set forth in the fee letter, dated June 28,
1994, from Chemical to the Company.

                 SECTION 2.9  Reduction of the Commitments.  The Company shall
have the right, upon at least three Business Days' notice to the Administrative
Agent, to terminate in whole or reduce ratably in part the unused portions of
the respective Commitments of the Lenders, provided that each partial reduction
shall be in
<PAGE>   27
                                                                              23



the aggregate amount of $10,000,000 or any whole multiple of $1,000,000 in
excess thereof.

                 SECTION 2.10  Repayment.  The Borrowers shall repay to each
Lender on the Termination Date the aggregate principal amount of the Advances
then owing to such Lender.

                 SECTION 2.11  Interest on Revolving Credit Advances.  (a)
Ordinary Interest.  The Borrowers shall pay interest on the unpaid principal
amount of each Revolving Credit Advance owing to each Lender from the date of
such Advance until such principal amount is due (whether at stated maturity, by
acceleration or otherwise), at the following rates:

                      (i)   Base Rate Advances.  During such periods as such
         Advance is a Base Rate Advance, a rate per annum equal at all times to
         the Base Rate in effect from time to time, payable quarterly in
         arrears on the last day of each March, June, September and December
         during such periods and on the date such Base Rate Advance shall be
         Converted or due (whether at stated maturity, by acceleration or
         otherwise).

                      (ii)  Eurodollar Rate Advances.  During such periods as
         such Advance is a Eurodollar Rate Advance, at a rate per annum equal
         at all times during each Interest Period for such Advance to the sum
         of the Eurodollar Rate for such Interest Period plus the Eurodollar
         Rate Margin in effect from time to time, payable on the last day of
         each such Interest Period and, if any such Interest Period has a
         duration of more than three months, on each day which occurs during
         such Interest Period every three months from the first day of such
         Interest Period.

                 (b)  Default Interest.  The applicable Borrower shall pay
interest on the unpaid principal amount of each Revolving Credit Advance to it
that is not paid when due (whether at stated maturity, by acceleration or
otherwise) from the date on which such amount is due until such amount is paid
in full, payable on demand, at a rate per annum equal at all times (i) from
such due date to the last day of the then existing Interest Period in the case
of each Eurodollar Rate Advance, to 1% per annum above the interest rate per
annum required to be paid on such Advance immediately prior to the date on
which such amount became due, and (ii) from and after the last day of the then
existing Interest Period, and at all times in the case of any Base Rate
Advance, to 1% per annum above the Base Rate in effect from time to time.

                 SECTION 2.12  Additional Interest on Eurodollar Rate Advances.
If any Lender shall determine in good faith that reserves under regulations of
the Board of Governors of the Federal Reserve System are required to be
maintained by it in respect of, or a portion of its costs of maintaining
reserves under such regulations is properly attributable to, one or more
<PAGE>   28
                                                                              24



of its Eurodollar Rate Advances, the applicable Borrower shall pay to such
Lender additional interest on the unpaid principal amount of each such
Eurodollar Rate Advance to it (other than any such additional interest accruing
to a particular Lender in respect of periods prior to the 30th day preceding
the date notice of such interest is given by such Lender as provided in this
Section 2.12), payable on the same day or days on which interest is payable on
such Advance, at an interest rate per annum equal at all times during each
Interest Period for such Advance to the excess of (i) the rate obtained by
dividing the Eurodollar Rate for such Interest Period by a percentage equal to
100% minus the Eurodollar Reserve Percentage, if any, for such Lender for such
Interest Period over (ii) the Eurodollar Rate for such Interest Period.  The
amount of such additional interest (if any) shall be determined by each Lender,
and such Lender shall furnish written notice of the amount of such additional
interest to the Company and the Administrative Agent, which notice shall be
conclusive and binding for all purposes, absent manifest error.

                 SECTION 2.13  Interest Rate Determination.  (a)  Each
Reference Lender agrees to furnish to the Administrative Agent timely
information for the purpose of determining the Eurodollar Rate.  If any one or
more of the Reference Lenders shall not furnish such timely information to the
Administrative Agent for the purpose of determining any such interest rate, the
Administrative Agent shall determine such interest rate on the basis of timely
information furnished by the remaining Reference Lenders.

                 (b)  The Administrative Agent shall give prompt notice to the
Company and the Lenders of the applicable interest rate determined by the
Administrative Agent for purposes of Section 2.11(a)(i) or (ii), and the
applicable rate, if any, furnished by each Reference Lender for the purpose of
determining the applicable interest rate under Section 2.11(a)(ii).

                 (c)  If fewer than two Reference Lenders furnish timely
information to the Administrative Agent for determining the Eurodollar Rate for
any Eurodollar Rate Advances,

                      (i)   the Administrative Agent shall give the Company and
         each Lender prompt notice thereof by telephone (confirmed in writing)
         that the interest rate cannot be determined for such Eurodollar Rate
         Advances,

                      (ii)  each such Advance will automatically, on the last
         day of the then existing Interest Period therefor, Convert into a Base
         Rate Advance (or if such Advance is then a Base Rate Advance, will
         continue as a Base Rate Advance), and

                    (iii)   the obligations of the Lenders to make, or to
Convert Advances into, Eurodollar Rate Advances shall be
<PAGE>   29
                                                                              25



         suspended until the Administrative Agent shall notify the Company and
         the Lenders that the circumstances causing such suspension no longer
         exist.

                 (d)  If, with respect to any Eurodollar Rate Advances, the
Majority Lenders determine and give notice to the Administrative Agent that, as
a result of conditions in or generally affecting the London interbank
eurodollar market, the rates of interest determined on the basis of the
Eurodollar Rate for any Interest Period for such Advances will not adequately
reflect the cost to such Majority Lenders of making, funding or maintaining
their respective Eurodollar Rate Advances for such Interest Period, the
Administrative Agent shall forthwith so notify the Company and the Lenders,
whereupon,

                      (i)   each such Advance will automatically, on the last
         day of the then existing Interest Period therefor, Convert into a Base
         Rate Advance, and

                      (ii)  the obligation of the Lenders to make, or to
         Convert Advances into, Eurodollar Rate Advances shall be suspended
         until the Administrative Agent shall notify the Company and the
         Lenders that the circumstances causing such suspension no longer
         exist.

                 (e)  If the applicable Borrower shall fail to select the
duration of any Interest Period for any Eurodollar Rate Advances in accordance
with the provisions contained in the definition of "Interest Period" in Section
1.1, the Administrative Agent will forthwith so notify the applicable Borrower
and the Lenders and such Advances will automatically, on the last day of the
then existing Interest Period therefor, Convert into Base Rate Advances.

                 (f)  On the date on which the aggregate unpaid principal
amount of Eurodollar Rate Advances comprising any Borrowing shall be reduced,
by payment or prepayment or otherwise, to less than $10,000,000, such
Eurodollar Rate Advances shall automatically Convert into Base Rate Advances,
and on and after such date the right of the applicable Borrower to Convert such
Advances into Eurodollar Rate Advances shall terminate; provided, however, that
if and so long as each such Eurodollar Rate Advance shall have the same
Interest Period as Eurodollar Rate Advances comprising another Borrowing or
other Borrowings, and the aggregate unpaid principal amount of all such
Eurodollar Rate Advances shall equal or exceed $20,000,000, the applicable
Borrower shall have the right to continue all such Advances as, or to Convert
all such Advances into Eurodollar Rate Advances having the same Interest
Period.

                 (g)  If any Reference Lender shall for any reason no longer
have a Commitment or any Revolving Credit Advances, such Reference Lender shall
thereupon cease to be a Reference Lender, and if, as a result, there shall only
be one Reference Lender
<PAGE>   30
                                                                              26



remaining, the Administrative Agent (after consultation with the Company and
the Lenders) shall, by notice to the Company and the Lenders, designate another
Lender as a Reference Lender so that there shall at all times be at least two
Reference Lenders.

                 SECTION 2.14  Voluntary Conversion of Advances.  Any Borrower
may on any Business Day, upon notice given to the Administrative Agent, not
later than 10:00 A.M. (New York City time) on the Business Day of the proposed
Conversion of Eurodollar Rate Advances to Base Rate Advances and not later than
12:00 noon (New York City time) on the third Business Day prior to the date of
the proposed Conversion in the case of a Conversion of Base Rate Advances to
Eurodollar Rate Advances, and subject to the provisions of Sections 2.13, 2.16
and 2.18, Convert all Advances of one Type comprising the same Borrowing into
Advances of another Type; provided, however, that any Conversion of any
Eurodollar Rate Advances into Base Rate Advances made on any day other than the
last day of an Interest Period for such Eurodollar Rate Advances shall be
subject to the provisions of Section 9.4(b).  Each such notice of a Conversion
shall, within the restrictions specified above, specify (a) the date of such
Conversion, (b) the Advances to be Converted, and (c) if such Conversion is
into Eurodollar Rate Advances, the duration of the Interest Period for each
such Advance.

                 SECTION 2.15  Prepayments.  Any Borrower may upon (a) in the
case of Eurodollar Rate Advances, at least two Business Days' notice and (b) in
the case of Base Rate Advances, telephonic notice not later than 12:00 noon
(New York City time) on the date of prepayment, to the Administrative Agent
which specifies the proposed date and aggregate principal amount of the
prepayment and the Type of Advances to be prepaid, and if such notice is given
such Borrower shall, prepay the outstanding principal amounts of the Advances
comprising the same Borrowing in whole or ratably in part, together with
accrued interest to the date of such prepayment on the amount prepaid;
provided, however, that (i) each partial prepayment shall be in an aggregate
principal amount not less than $10,000,000 or an integral multiple of
$1,000,000 in excess thereof and (ii) in the event of any such prepayment of
Eurodollar Rate Advances on any day other than the last day of an Interest
Period for such Eurodollar Rate Advances, such Borrower shall be obligated to
reimburse the Lenders in respect thereof pursuant to, and to the extent
required by, Section 9.4(b); provided, further, however, that such Borrower
will use its best efforts to give notice to the Administrative Agent of the
proposed prepayment of Base Rate Advances on the Business Day prior to the date
of such proposed prepayment.

                 SECTION 2.16  Increased Costs.  (a)  If, due to either (i) the
introduction after the date of this Agreement of or any change after the date
of this Agreement (including any change by way of imposition or increase of
reserve requirements or assessments other than those referred to in the
definition of
<PAGE>   31
                                                                              27



"Eurodollar Reserve Percentage," "C/D Reserve Percentage" or "C/D Assessment
Rate" contained in Section 1.1) in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request issued or made
after the date of this Agreement from or by any central bank or other
governmental authority (whether or not having the force of law), in each case
above other than those referred to in Section 2.17, there shall be any increase
in the cost to any Lender of agreeing to make, fund or maintain, or of making,
funding or maintaining, Eurodollar Rate Advances funded in the interbank
Eurodollar market, then the Borrowers shall from time to time, upon demand by
such Lender (with a copy of such demand to the Administrative Agent), pay to
the Administrative Agent for the account of such Lender additional amounts
sufficient to reimburse such Lender for all such increased costs (except those
costs incurred more than 60 days prior to the date of such demand; for the
purposes hereof any cost or expense allocable to a period prior to the
publication or effective date of such an introduction, change, guideline or
request shall be deemed to be incurred on the later of such publication or
effective date).  Each Lender agrees to use its best efforts promptly to notify
the Company of any event referred to in clause (i) or (ii) above, provided that
the failure to give such notice shall not affect the rights of any Lender under
this Section 2.16(a) (except as otherwise expressly provided above in this
Section 2.16(a)).  A certificate as to the amount of such increased cost,
submitted to the Company and the Administrative Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error.  After one or
more Lenders have notified the Company of any increased costs pursuant to this
Section 2.16, the Company may specify by notice to the Administrative Agent and
the affected Lenders that, after the date of such notice whenever the election
of Eurodollar Rate Advances by the applicable Borrower for an Interest Period
or portion thereof would give rise to such increased costs, such election shall
not apply to the Revolving Credit Advances of such Lenders during such Interest
Period or portion thereof, and, in lieu thereof, such Revolving Credit Advances
shall during such Interest Period or portion thereof be Base Rate Advances.
Each Lender agrees to use its best efforts (including, without limitation, a
reasonable effort to change its lending office or to transfer its affected
Advances to an affiliate of such Lender) to avoid, or minimize the amount of,
any demand for payment from the Borrowers under this Section 2.16.

                 (b)  In the event that any Lender shall change its lending
office and such change results (at the time of such change) in increased costs
to such Lender, the Borrowers shall not be liable to such Lender for such
increased costs incurred by such Lender to the extent, but only to the extent,
that such increased costs shall exceed the increased costs which such Lender
would have incurred if the lending office of such Lender had not been so
changed, but, subject to subsection (a) above and to Section 2.18, nothing
herein shall require any Lender to change its lending office for any reason.
<PAGE>   32
                                                                              28




                 SECTION 2.17  Increased Capital.  If either (a) the
introduction of or any change in or in the interpretation of any law or
regulation or (b) compliance by any Lender with any guideline or request from
any central bank or other governmental authority (whether or not having the
force of law) affects or would affect the amount of capital required or
expected to be maintained by such Lender or any corporation controlling such
Lender and such Lender determines that the amount of such capital is increased
by or based upon the existence of such Lender's commitment to lend hereunder
and other commitments of this type, then, within ten days after demand, and
delivery to the Company of the certificate referred to in the last sentence of
this Section 2.17 by such Lender (with a copy of such demand to the
Administrative Agent), the applicable Borrowers shall pay to the Administrative
Agent for the account of such Lender, from time to time as specified by such
Lender, additional amounts sufficient to compensate such Lender or such
corporation in the light of such circumstances, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence
of such Lender's commitment to lend hereunder (except any such increase in
capital incurred more than, or compensation attributable to the period before,
90 days prior to the date of such demand; for the purposes hereof any increase
in capital allocable to, or compensation attributable to, a period prior to the
publication or effective date of such an introduction, change, guideline or
request shall be deemed to be incurred on the later of such publication or
effective date).  Each Lender agrees to use its best efforts promptly to notify
the Company of any event referred to in clause (a) or (b) above, provided that
the failure to give such notice shall not affect the rights of any Lender under
this Section 2.17 (except as otherwise expressly provided above in this Section
2.17).  A certificate in reasonable detail as to the basis for, and the amount
of, such compensation submitted to the Company by such Lender shall, in the
absence of manifest error, be conclusive and binding for all purposes.

                 SECTION 2.18  Illegality.  Notwithstanding any other provision
of this Agreement, if the introduction of or any change in or in the
interpretation of any law or regulation shall make it unlawful, or any central
bank or other governmental authority shall assert that it is unlawful, for any
Lender or its lending office to perform its obligations hereunder to make
Eurodollar Rate Advances or to continue to fund or maintain such Advances
hereunder, such Lender may, by notice to the Company and the Administrative
Agent, suspend the right of the Borrowers to elect Eurodollar Rate Advances
from such Lender and, if necessary in the reasonable opinion of such Lender to
comply with such law or regulation, Convert all such Eurodollar Rate Advances
of such Lender to Base Rate Advances at the latest time permitted by the
applicable law or regulation, and such suspension and, if applicable, such
Conversion shall continue until such Lender notifies the Company and the
Administrative Agent that the circumstances making it unlawful for such Lender
to perform such
<PAGE>   33
                                                                              29



obligations no longer exist (which such Lender shall promptly do when such
circumstances no longer exist).  So long as the obligation of any Lender to
make Eurodollar Rate Advances has been suspended under this Section 2.18, all
Notices of Borrowing specifying Advances of such Type shall be deemed, as to
such Lender, to be requests for Base Rate Advances.  Each Lender agrees to use
its best efforts (including, without limitation, a reasonable effort to change
its lending office or to transfer its affected Advances to an affiliate) to
avoid any such illegality.

                 SECTION 2.19  Payments and Computations.  (a)  The Borrowers
shall make each payment hereunder (including, without limitation, under Section
2.8, 2.10 or 2.11) and under the Notes, whether the amount so paid is owing to
any or all of the Lenders or to the Administrative Agent, not later than 12:00
noon (New York City time) without setoff, counterclaim, or any other deduction
whatsoever, on the day when due in Dollars to the Administrative Agent at its
address at 270 Park Avenue, New York, New York 10017, Reference: El Paso
Natural Gas Company, or at such other location designated by notice to the
Company from the Administrative Agent and agreed to by the Company, in same day
funds.  The Administrative Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal or interest or
facility fees ratably (other than amounts payable pursuant to Section 2.12,
2.16, 2.17, 2.18 or 2.20) according to the respective amounts of such
principal, interest or facility fees then due and owing to the Lenders, and
like funds relating to the payment of any other amount payable to any Lender to
such Lender, in each case to be applied in accordance with the terms of this
Agreement.  Upon its acceptance of an Assignment and Acceptance and recording
of the information contained therein in the Register pursuant to Section
9.7(d), from and after the effective date specified in such Assignment and
Acceptance, the Administrative Agent shall make all payments hereunder and
under the Notes in respect of the interest assigned thereby to the Lender
assignee thereunder, and the parties to such Assignment and Acceptance shall
make all appropriate adjustments in such payments for periods prior to such
effective date directly between themselves.

                 (b)  All computations of interest based on the Base Rate and
of facility fees shall be made by the Administrative Agent on the basis of a
year of 365 or 366 days, as the case may be, and all computations of interest
based on the Eurodollar Rate or the Effective Federal Funds Rate shall be made
by the Administrative Agent, and all computations of interest pursuant to
Section 2.12 shall be made by each Lender with respect to its own Advances, on
the basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period
for which such interest or fees are payable.  Each determination by the
Administrative Agent (or, in the case of Section 2.12, 2.16, 2.17, 2.18 or
2.20, by each Lender with respect to its own Advances) of an interest rate or
an increased cost or increased

                                                                              30



capital or of illegality hereunder shall be conclusive and binding for all
purposes if made reasonably and in good faith.

                 (c)  Whenever any payment hereunder or under the Notes shall
be stated to be due on a day other than a Business Day, such payment shall be
made on the next succeeding Business Day, and such extension of time shall in
such case be included in the computation of payment of interest; provided,
however, if such extension would cause payment of interest on or principal of
Eurodollar Rate Advances to be made in the next following calendar month, such
payment shall be made on the next preceding Business Day.

                 (d)  Unless the Administrative Agent shall have received
notice from the Company or any other applicable Borrower prior to the date on
which any payment is due to the Lenders hereunder that the applicable Borrower
will not make such payment in full, the Administrative Agent may assume that
the applicable Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender.  If and to the extent the applicable
Borrower shall not have so made such payment in full to the Administrative
Agent, each Lender shall repay to the Administrative Agent forthwith on demand
such amount distributed to such Lender together with interest thereon, for each
day from the date such amount is distributed to such Lender until the date such
Lender repays such amount to the Administrative Agent, at a rate equal to the
Effective Federal Funds Rate for such day.

                 SECTION 2.20  Taxes.  (a)  Any and all payments by the
Borrowers hereunder or under the Notes to each Indemnified Party shall be made,
in accordance with Section 2.19, free and clear of and without deduction for
any and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding, all taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, imposed by the jurisdiction under the laws of which such
Indemnified Party is organized, domiciled, resident or doing business, or any
political subdivision thereof or by any jurisdiction in which such Indemnified
Party holds any interest in connection with this Agreement or any Note
(including, without limitation, in the case of each Lender, the jurisdiction of
such Lender's lending office) or any political subdivision thereof, other than
by any jurisdiction with which the Indemnified Party's connection arises solely
from having executed, delivered or performed obligations or received a payment
under, or enforced, this Agreement or any Note (all such non-excluded taxes,
levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").  If any Borrower shall be required by law
to deduct any Taxes from or in respect of any sum payable hereunder or under
any Note to any Indemnified Party, (i) the sum payable
<PAGE>   35
                                                                              31



shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.20) such Indemnified Party receives an amount equal to the sum
it would have received had no such deductions been made, (ii) such Borrower
shall make or cause to be made such deductions and (iii) such Borrower shall
pay or cause to be paid the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law, provided that
the Borrowers shall not be required to pay any additional amount (and shall be
relieved of any liability with respect thereto) pursuant to this subsection (a)
to any Indemnified Party that either (A) on the date such Lender became an
Indemnified Party hereunder, (y) was not entitled to submit a U.S. Internal
Revenue Service form 1001 (relating to such Indemnified Party, and entitling it
to a complete exemption from United States withholding taxes on all amounts to
be received by such Indemnified Party pursuant to this Agreement) and a U.S.
Internal Revenue Service form 4224 (relating to all amounts to be received by
such Indemnified Party pursuant to this Agreement) and (z) was not a United
States person (as such term is defined in Section 7701(a)(30) of the Internal
Revenue Code) or (B) has failed to submit any form or certificate that it was
required to file or provide pursuant to subsection (d) of this Section 2.20 and
is entitled to file or give, as applicable, under applicable law, provided,
further, that should an Indemnified Party become subject to Taxes because of
its failure to deliver a form required hereunder, the Borrowers shall take such
steps as such Indemnified Party shall reasonably request to assist such
Indemnified Party to recover such Taxes, and provided further that each
Indemnified Party, with respect to itself, agrees to indemnify and hold
harmless the Borrowers from any taxes, penalties, interest and other expenses,
costs and losses incurred or payable by the Borrowers as a result of the
failure of any of the Borrowers to comply with its obligations under clause
(ii) or (iii) above in reliance on any form or certificate provided to it by
such Indemnified Party pursuant to this Section 2.20.  If any Indemnified Party
receives a net credit or refund in respect of such Taxes or amounts so paid by
the Borrowers, it shall promptly notify the Company of such net credit or
refund and shall promptly pay such net credit or refund to the applicable
Borrower, provided that the applicable Borrower agrees to return such net
credit or refund if the Indemnified Party to which such net credit or refund is
applicable is required to repay it.

                 (b)  In addition, each Borrower agrees to pay any present or
future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies which arise from any payment made by such Borrower
hereunder or under the Notes or from the execution, delivery or performance of,
or otherwise with respect to, this Agreement or the Notes (hereinafter referred
to as "Other Taxes").
<PAGE>   36
                                                                              32



                 (c)  Each Borrower will indemnify each Indemnified Party and
the Administrative Agent for the full amount of Taxes or Other Taxes
(including, without limitation, any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this Section 2.20) paid by such
Indemnified Party and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto except as a result of the
gross negligence (which shall in any event include the failure of such
Indemnified Party to provide to the Borrowers any form or certificate that it
was required to provide pursuant to subsection (d) below) or willful misconduct
of such Indemnified Party, whether or not such Taxes or Other Taxes were
correctly or legally asserted.  This indemnification shall be made within 30
days from the date such Indemnified Party makes written demand therefor.

                 (d)      On or prior to the date on which each Indemnified
Party organized under the laws of a jurisdiction outside the United States
becomes an Indemnified Party hereunder, such Indemnified Party shall provide
the Company with U.S. Internal Revenue Service form 1001 or 4224, as
appropriate, or any successor form prescribed by the U.S. Internal Revenue
Service, certifying that such Indemnified Party is fully exempt from United
States withholding taxes with respect to all payments to be made to such
Indemnified Party hereunder, or other documents satisfactory to the Company
indicating that all payments to be made to such Indemnified Party hereunder are
fully exempt from such taxes.  Thereafter and from time to time (but only so
long as such Indemnified Party remains lawfully able to do so), each such
Indemnified Party shall submit to the Company such additional duly completed
and signed copies of one or the other of such Forms (or such successor Forms as
shall be adopted from time to time by the relevant United States taxing
authorities) as may be (i) notified by any Borrower to such Indemnified Party
and (ii) required under then-current United States law or regulations to avoid
United States withholding taxes on payments in respect of all amounts to be
received by such Indemnified Party pursuant to this Agreement or the Notes.
Upon the request of any Borrower from time to time, each Indemnified Party that
is a United States person (as such term is defined in Section 7701(a)(30) of
the Internal Revenue Code) shall submit to the Company a certificate to the
effect that it is such a United States person.  If any Indemnified Party
determines, as a result of any change in applicable law, regulation or treaty,
or in any official application or interpretation thereof, that it is unable to
submit to the Company any form or certificate that such Indemnified Party is
obligated to submit pursuant to this subsection (d), or that such Indemnified
Party is required to withdraw or cancel any such form or certificate previously
submitted, such Indemnified Party shall promptly notify the Company of such
fact.

                 (e)      Any Indemnified Party claiming any additional amounts
payable pursuant to this Section 2.20 shall use its best efforts (consistent
with its internal policy and legal and
<PAGE>   37
                                                                              33



regulatory restrictions) to change the jurisdiction of its lending office if
the making of such a change would avoid the need for, or reduce the amount of,
any such additional amounts which may thereafter accrue and would not, in the
reasonable judgment of such Indemnified Party, be otherwise disadvantageous to
such Indemnified Party.

               (f)      Without prejudice to the survival of any other
agreement of the Borrowers hereunder, the agreements and obligations of the
Borrowers and each Indemnified Party contained in this Section 2.20 shall
survive the payment in full of principal and interest hereunder and under the
Notes.

               (g)  Any other provision of this Agreement to the contrary
notwithstanding, any amounts which are payable by any Borrower under this
Section 2.20 shall not be payable under Section 2.16.

                 SECTION 2.21  Sharing of Payments, Etc.  If any Lender shall
obtain any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) on account of the Advances made by it (other
than pursuant to Section 2.12, 2.16, 2.17, 2.18 or 2.20) in excess of its
ratable share of payments on account of the Advances obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the Advances made by them as shall be necessary to cause such
purchasing Lender to share the excess payment ratably with each of them,
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each
Lender shall be rescinded and each Lender shall repay to the purchasing Lender
the purchase price to the extent of such recovery together with an amount equal
to such Lender's ratable share (according to the proportion of (a) the amount
of such Lender's required repayment to (b) the total amount so recovered from
the purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered.  Each Borrower
agrees that any Lender so purchasing a participation from another Lender
pursuant to this Section may, to the fullest extent permitted by law, exercise
all its rights of payment (including the right of set-off) with respect to such
participation as fully as if such Lender were the direct creditor of such
Borrower in the amount of such participation.

                 SECTION 2.22  Use of Proceeds.  Proceeds of the Advances may
be used for general corporate purposes of the Company and its Subsidiaries,
including, without limitation, for acquisitions and for payment of commercial
paper issued by the Company and to refinance the loans under the Company's
Revolving Credit Agreement, dated as of February 11, 1992.

as soon as the Administrative Agent determines that all of the conditions to
effectiveness of this Agreement specified in this Section 3.1 shall have been
fulfilled on or before September 30, 1994, the Administrative Agent shall
furnish written notice to the Company and the Lenders to the effect that it has
so determined, and such notice by the Administrative Agent shall constitute
conclusive evidence that this Agreement shall have become effective for all
purposes.

                 SECTION 3.2  Conditions Precedent to Initial Advances to Any

                 SECTION 3.3  Conditions Precedent to Each Borrowing.  The
obligation of each Lender to make an Advance (including the initial Advance) on
the occasion of any Borrowing shall be subject to the conditions precedent that
on the date of such Borrowing this Agreement shall have become effective
pursuant to Section 3.1 and, before and immediately after giving effect to such
Borrowing and to the application of the proceeds therefrom, the following
statements shall be true and correct, and the giving by the Company of the
applicable Notice of Borrowing and the acceptance by the applicable Borrower of
the proceeds of such Borrowing shall constitute its representation and warranty
that on and as of the date of such Borrowing, before and immediately after
giving effect thereto and to the application of the proceeds therefrom, the
following statements are true and correct:

                 (a)      Each representation and warranty contained in Section

         would constitute an Event of Default but for the requirement that
         notice be given or time elapse or both.

                         REPRESENTATIONS AND WARRANTIES

                 SECTION 4.1  Representations and Warranties of the Borrowers.
Each Borrower represents and warrants as follows:

                 (a)      The Company is a corporation duly incorporated,
         validly existing and in good standing under the laws of the State of
         Delaware.  Each Principal Subsidiary is duly incorporated, validly
         existing and in good standing in the jurisdiction of its
         incorporation.  The Company and each Principal Subsidiary possess all
         corporate powers and all other authorizations and licenses necessary
         to engage in its

                                                                              37



         business and operations as now conducted, the failure to obtain or
         maintain which would have a Material Adverse Effect.

                 (b)  The execution, delivery and performance by each Borrower
         of this Agreement, each Joinder Agreement, if any, to which it is a
         party and its Notes (as applicable) are within such Borrower's
         corporate powers, have been duly authorized by all necessary corporate
         action, and do not contravene (i) such Borrower's charter or by-laws
         or (ii) law or any contractual restriction binding on or affecting
         such Borrower.

                 (c)      No authorization or approval or other action by, and
         no notice to or filing with, any governmental authority or regulatory
         body is required for the due execution, delivery and performance by
         such Borrower of this Agreement, each Joinder Agreement, if any, to
         which it is a party or its Notes (as applicable), except filings
         necessary to comply with laws, rules, regulations and orders required
         in the ordinary course to comply with ongoing obligations of such
         Borrower under Section 5.1(a) and (b).

                 (d)      This Agreement constitutes, and its Notes and each
         Joinder Agreement, if any, to which it is a party (as applicable) when
         delivered hereunder shall constitute, the legal, valid and binding
         obligations of each Borrower enforceable against such Borrower in
         accordance with their respective terms, except as may be limited by
         any applicable bankruptcy, insolvency, reorganization, moratorium or
         similar laws affecting creditors' rights generally or by general
         principles of equity.

                 (e)      The consolidated balance sheet of the Company and its
         consolidated Subsidiaries as at December 31, 1993, and the related
         consolidated statements of income and cash flows of the Company and
         its consolidated Subsidiaries for the fiscal year then ended, reported
         on by Coopers & Lybrand, independent public accountants, copies of
         which have been furnished to the Administrative Agent and the Lenders
         prior to the date hereof, fairly present the consolidated financial
         condition of the Company and its consolidated Subsidiaries as at such
         date and the consolidated results of the operations of the Company and
         its consolidated Subsidiaries for the period ended on such date, all
         in accordance with generally accepted accounting principles
         consistently applied, and since December 31, 1993, there has been no
         material adverse change in such condition or operations.  The
         unaudited consolidated balance sheet of the Company and its
         consolidated Subsidiaries as of March 31, 1994, and the related
         consolidated statements of income and cash flows of the Company and
         its consolidated Subsidiaries for the three months then ended,
         certified by the chief financial officer of the Company, copies of
         which have been

                                                                              38



         furnished to the Administrative Agent and the Lenders prior to the
         date hereof, fairly present the consolidated results of operations of
         the Company and its consolidated Subsidiaries for the three months
         then ended, all in accordance with generally accepted accounting
         principles consistently applied and subject to normal year-end audit
         adjustments.

                 (f)      There is no action, suit or proceeding pending, or to
         the knowledge of any Borrower threatened, against or involving the
         Company or any Principal Subsidiary in any court, or before any
         arbitrator of any kind, or before or by any governmental body, which
         in the reasonable judgment of the Company (taking into account the
         exhaustion of all appeals) would have a Material Adverse Effect, or
         which purports to affect the legality, validity, binding effect or

         filed all tax returns required to be filed, and have duly paid and
         discharged all taxes, assessments and governmental charges upon it or
         against its properties now due and payable, the failure to pay which
         would have a Material Adverse Effect, unless and to the extent only
         that the same are being contested in good faith and by appropriate
         proceedings by the Company or the appropriate Subsidiary.

                 (h)      The Company and each Principal Subsidiary have good
         title to their respective properties and assets, free and clear of all
         mortgages, liens and encumbrances, except for mortgages, liens and
         encumbrances (including covenants, restrictions, rights, easements and
         minor irregularities in title) which do not materially interfere with
         the business or operations of the Company or such Subsidiary as
         presently conducted or which are permitted by Section 5.2(a), and
         except that no representation or warranty is being made with respect
         to Margin Stock.

                 (i)      No Termination Event has occurred or is reasonably
         expected to occur with respect to any Plan which, with the giving of
         notice or lapse of time, or both, would constitute an Event of Default
         under Section 7.1(g).

               (j)        Each Plan has complied with the applicable provisions
         of ERISA and the Code where the failure to so comply would reasonably
         be expected to result in an aggregate liability that would exceed 10%

         Plan as at such date and the results of operations of such Plan for
         the plan year ended on such date.

                 (l)      Neither the Company nor any ERISA Affiliate has
         incurred, or is reasonably expected to incur, any Withdrawal Liability
         to any Multiemployer Plan which, when aggregated with all other
         amounts required to be paid to Multiemployer Plans in connection with
         Withdrawal Liability (as of the date of determination), would exceed
         10% of the Net Worth of the Company.

                 (m)      Neither the Company nor any ERISA Affiliate has
         received any notification that any Multiemployer Plan is in
         reorganization, insolvent or has been terminated, within the meaning
         of Title IV of ERISA, and no Multiemployer Plan is reasonably expected
         to be in reorganization, insolvent or to be terminated within the
         meaning of Title IV of ERISA the effect of which reorganization,
         insolvency or termination would be the occurrence of an Event of
         Default under Section 7.1(i).

                 (n)      The Borrowers are not engaged in the business of
         extending credit for the purpose of purchasing or carrying Margin
         Stock, and no proceeds of any Advance will be used to extend credit to
         others (other than to any Subsidiary of the Company) for the purpose
         of purchasing or carrying Margin Stock.

         controlled by an "investment company" within the meaning of the
         Investment Company Act of 1940, as amended.

                 (p)      No Borrower is a "holding company" or a "subsidiary
         company" of a "holding company" within the meaning of the Public
         Utility Holding Company Act of 1935, as amended.

All representations and warranties made by the Borrowers herein or made in any
certificate delivered pursuant hereto shall survive the making of the Advances

                                   ARTICLE VI

                                   GUARANTEES

                 SECTION 6.1  Guarantees.  (a)  The Company hereby
unconditionally and irrevocably guarantees to the Administrative Agent, for the
ratable benefit of the Lenders and their respective successors, indorsees,
transferees and assigns, the prompt and complete payment by each Borrowing
Subsidiary when due (whether at the stated maturity, by acceleration or
otherwise) of the Obligations owing by each Borrowing Subsidiary.

                 (b)  Subject to the provisions of Section 6.1(c), each
Borrowing Subsidiary hereby, jointly and severally, unconditionally and
irrevocably guarantees to the Administrative Agent, for the ratable benefit of
the Lenders and their respective successors, indorsees, transferees and
assigns, the prompt and complete payment by the Company when due (whether at
the stated maturity, by acceleration or otherwise) of the Obligations owing by
the Company.

                 (c)  Anything in this Article VI to the contrary
notwithstanding, the maximum liability of each Borrowing Subsidiary under this
Article VI shall in no event exceed the amount which can be guaranteed by such
Borrowing Subsidiary under applicable federal and state laws relating to the
insolvency of debtors.

                 (d)  Each Borrowing Subsidiary agrees that the Obligations
owing by the Company may at any time and from time to time exceed the amount of
the liability of such Borrowing Subsidiary under this Article VI without
impairing the guarantee of such Borrowing Subsidiary under this Article VI or
affecting the rights and remedies of the Administrative Agent or any Lender
under this Article VI.

                 (e)      No payment or payments made by any Borrower or any
other Person or received or collected by the Administrative Agent or any Lender
from any Borrower or any other Person by virtue of any action or proceeding or

reduce, release or otherwise affect the liability of the Borrowers under this
Article VI which shall, notwithstanding any such payment or payments, continue
until the Obligations are paid in full and the Commitments are terminated.

                 (f)      Each Borrower agrees that whenever, at any time, or

                 SECTION 6.2  No Subrogation.  (a)  Notwithstanding anything to
the contrary contained herein, the Company hereby irrevocably waives all rights
which may have arisen in connection with this Agreement to be subrogated to any
of the rights (whether contractual, under the Bankruptcy Code, including
Section 509 thereof, under common law or otherwise) of any Lender against any
Borrowing Subsidiary or against any collateral security or guarantee or right
of offset held by such Lender for the payment of the Obligations.  The Company
hereby further irrevocably waives all contractual, common law, statutory or
other rights of reimbursement, contribution, exoneration or indemnity (or any
similar right) from or against each Borrowing Subsidiary or any other Person
which may have arisen in connection with this Agreement.  So long as the
Obligations remain outstanding, if any amount shall be paid by or on behalf of
any Borrowing Subsidiary to the Company on account of any of the rights waived
in this Section, such amount shall be held by the Company in trust, segregated
from other funds of the Company, and shall, forthwith upon receipt by the
Company, be turned over to the Administrative Agent in the exact form received
by the Company (duly indorsed by the Company to the Administrative Agent, if
required), to be applied against the Obligations, whether matured or unmatured,
in such order as the Administrative Agent may determine.  The provisions of
this Section shall survive the termination of this Agreement and the payment in
full of the Obligations and the termination of the Commitments.

                 (b)      Notwithstanding any payment or payments made by any
Borrowing Subsidiary under this Article VI or any set- off or application of
funds of such Borrowing Subsidiary by the Administrative Agent or any Lender,
such Borrowing Subsidiary shall not be entitled to be subrogated to any of the
rights of the Administrative Agent or any Lender against the Company or against
any collateral security or guarantee or right of offset held by the
Administrative Agent or any Lender for the payment of the Obligations, nor
shall such Borrowing Subsidiary seek or be entitled to seek any contribution or
reimbursement from the Company in respect of payments made by such Borrowing
Subsidiary hereunder, until all amounts owing to the Administrative Agent and
the Lenders by the Company on account of the Obligations are paid in full and
the Commitments are terminated.  If any amount shall be paid to any Borrowing
Subsidiary on account of such subrogation rights at any time when all of the
Obligations shall not have been paid in full, such amount shall be held by such
Borrowing Subsidiary in trust for the Administrative Agent and the Lenders,
segregated from other funds of such Borrowing Subsidiary, and shall, forthwith
upon receipt by such Borrowing Subsidiary, be turned over to the Administrative
Agent in the exact form received by such Borrowing Subsidiary (duly indorsed by
such Borrowing Subsidiary to the Administrative Agent, if required), to be
applied against the Obligations, whether matured or unmatured, in such order as
the Administrative Agent may determine.

                 SECTION 6.3  Amendments, etc. with respect to the Obligations;
Waiver of Rights.  Each Borrower shall remain obligated under this Article VI
notwithstanding that, without any reservation of rights against such Borrower,
and without notice to or further assent by such Borrower, any demand for
payment of any of the Obligations made by the Administrative Agent or any
Lender may be rescinded by the Administrative Agent or such Lender, and any of
the Obligations continued, and the Obligations, or the liability of any other
party upon or for any part thereof, or any collateral security or guarantee
therefor or right of offset with respect thereto, may, from time to time, in
whole or in part, be renewed, extended, amended, modified, accelerated,
compromised, waived, surrendered or released by the Administrative Agent or any
Lender, and this Agreement, any Notes and any other documents executed and
delivered in connection herewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Administrative Agent (or the Majority
Lenders, as the case may be) may deem advisable from time to time, and any
collateral security, guarantee or right of offset at any time held by the
Administrative Agent or any Lender for the payment of the Obligations may be
sold, exchanged, waived, surrendered or released.  Neither the Administrative
Agent nor any Lender shall have any obligation to protect, secure, perfect or
insure any Lien at any time held by it as security for the Obligations or for
this Agreement or any property subject thereto.  When making any demand
hereunder against any Borrower, the Administrative Agent or any Lender may, but
shall be under no obligation to, make a similar demand on the applicable
Borrowing Subsidiaries or any other guarantor, and any failure by the
Administrative Agent or any Lender to make any such demand or to collect any
payments from the other Borrowers or any such other guarantor or any release of
the other Borrowers or such other guarantor shall not relieve such Borrower of
its obligations or liabilities hereunder, and shall not impair or affect the
rights and remedies, express or implied, or as a matter of law, of the
Administrative Agent or any Lender against such Borrower For the purposes
hereof "demand" shall include the commencement and continuance of any legal
proceedings.

                 SECTION 6.4  Guarantee Absolute and Unconditional.  Each
Borrower waives any and all notice of the creation, renewal, extension or
accrual of any of the Obligations and notice of or proof of reliance by the
Administrative Agent or any Lender upon this Agreement or acceptance of this
Agreement; the Obligations, and any of them, shall conclusively be deemed to
have been created, contracted or incurred, or renewed, extended, amended or
waived, in reliance upon this Agreement; and all dealings between any Borrowing
Subsidiary or the Company, on the one hand, and the Administrative Agent and
the Lenders, on the other, shall likewise be conclusively presumed to have been
had or consummated in reliance upon this Agreement.  Each Borrower waives
diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon the Borrowing Subsidiaries or the Company (as applicable)
with respect to the Obligations.  The guarantee

                                                                              50



contained in this Article VI shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity,
regularity or enforceability of this Agreement, any Note, any of the
Obligations or any other collateral security therefor or guarantee or right of
offset with respect thereto at any time or from time to time held by the
Administrative Agent or any Lender, (b) any defense, set-off or counterclaim
(other than a defense of payment or performance) which may at any time be
available to or be asserted by any Borrower against the Administrative Agent or
any Lender, or (c) any other circumstance whatsoever (with or without notice to
or knowledge of any Borrower) which constitutes, or might be construed to
constitute, an equitable or legal discharge of any Borrower for the
Obligations, or of the Borrowers under this Agreement, in bankruptcy or in any
other instance.  When pursuing its rights and remedies hereunder against any
Borrower, the Administrative Agent and any Lender may, but shall be under no
obligation to, pursue such rights and remedies as it may have against any other
Borrower or any other Person or against any collateral security or guarantee
for the Obligations or any right of offset with respect thereto, and any
failure by the Administrative Agent or any Lender to pursue such other rights
or remedies or to collect any payments from other Borrowers or any such other
Person or to realize upon any such collateral security or guarantee or to
exercise any such right of offset, or any release of any other Borrower or any
such other Person or of any such collateral security, guarantee or right of
offset, shall not relieve any Borrower of any liability hereunder, and shall
not impair or affect the rights and remedies, whether express, implied or
available as a matter of law, of the Administrative Agent or any Lender against
such Borrower.  The guarantees contained in this Article VI shall remain in
full force and effect and be binding in accordance with and to the extent of
its terms upon each Borrower and its successors and assigns thereof, and shall
inure to the benefit of the Administrative Agent and the Lenders, and their
respective successors, indorsees, transferees and assigns, until all the
Obligations and the obligations of the Borrower under this Agreement shall have
been satisfied by payment in full and the Commitments shall be terminated,
notwithstanding that from time to time during the term of this Agreement the
Borrowers may be free from any Obligations.

                 SECTION 6.5  Reinstatement.  The provisions of this Article VI
shall continue to be effective, or be reinstated, as the case may be, if at any
time payment, or any part thereof, of any of the Obligations is rescinded or
must otherwise be restored or returned by the Administrative Agent or any
Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of any Borrower or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, any
Borrower or any substantial part of its property, or otherwise, all as though
such payments had not been made.

                 (j)      The guarantees contained in Article VI shall cease,
         for any reason, to be in full force and effect or any Borrower shall
         so assert;

then, and in any such event, the Administrative Agent shall at the request, or
may with the consent, of the Majority Lenders, by notice to the Company, (i)
declare the obligation of each Lender to make Advances to be terminated,
whereupon the same shall forthwith terminate, and (ii) declare the Notes, all

demand, protest or further notice of any kind, all of which are hereby
expressly waived by the Borrowers; provided, however, that if an Event of
Default under subsection (e) of this Section 7.1 (except under clause (i)(A)

                                  ARTICLE VIII

               THE ADMINISTRATIVE AGENT AND THE CAF ADVANCE AGENT

                 SECTION 8.1  Authorization and Action.  Each Lender hereby
appoints and authorizes the Administrative Agent and the CAF Advance Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent and the CAF Advance
Agent by the terms hereof, together with such powers as are reasonably
incidental thereto.  As to any matters not expressly provided for by this
Agreement (including, without limitation, enforcement of this Agreement or
collection of the Notes), the Administrative Agent and the CAF Advance Agent
shall not be required to exercise any discretion or take any action, but shall
be required to act or to refrain from acting (and shall be fully protected in
so acting or refraining from acting) upon the instructions of the Majority
Lenders, and such instructions shall be binding upon all Lenders and all
holders of Notes; provided, however, that the Administrative Agent and the CAF
Advance Agent shall not be required to take any action which exposes the
Administrative Agent or the CAF Advance Agent to personal liability or which is
contrary to this Agreement or applicable law.  The Administrative Agent and the
CAF Advance Agent agree to give to each Lender prompt notice of each notice
given to it by any Borrower pursuant to the terms of this Agreement.

                                                                              55




                 SECTION 8.2  Administrative Agent's and CAF Advance Agent's
Reliance, Etc.  None of the Administrative Agent, the CAF Advance Agent or any
of its respective directors, officers, agents or employees shall be liable for
any action taken or omitted to be taken by it or them under or in connection
with this Agreement, except for its or their own gross negligence or willful
misconduct.  Without limitation of the generality of the foregoing, the
Administrative Agent and the CAF Advance Agent:  (i) may treat the payee of any
Note as the holder thereof until the Administrative Agent receives and accepts
an Assignment and Acceptance entered into by the Lender which is the payee of
such Note, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 9.7; (ii) may consult with legal counsel (including counsel for the
Company), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith
by it in accordance with the advice of such counsel, accountants or experts;
(iii) makes no warranty or representation to any Lender and shall not be
responsible to any Lender for any statements, warranties or representations

observance of any of the terms, covenants or conditions of this Agreement on
the part of the Borrowers or to inspect the property (including the books and
records) of the Borrowers; (v) shall not be responsible to any Lender for the
due execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto; and (vi) shall incur no liability under or in respect of this Agreement
by acting upon any notice, consent, certificate or other instrument or writing
(which may be by telegram, telecopier, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

                 SECTION 8.3  Chemical and Affiliates.  With respect to its
Commitment, the Advances made by it and the Note issued to it, Chemical shall
have the same rights and powers under this Agreement as any other Lender and
may exercise the same as though it were not the Administrative Agent or the CAF
Advance Agent; and the term "Lender" or "Lenders" shall, unless otherwise
expressly indicated, include Chemical in its individual capacity. Chemical and
its affiliates may accept deposits from, lend money to, act as trustee under
indentures of, and generally engage in any kind of business with, the Company,
any of its Subsidiaries and any Person who may do business with or own
securities of the Company or any of its Subsidiaries, all as if Chemical were
not the Administrative Agent or the CAF Advance Agent and without any duty to
account therefor to the other Lenders.

                 SECTION 8.4  Lender Credit Decision.  Each Lender acknowledges
that it has, independently and without reliance upon the Administrative Agent,
the CAF Advance Agent or any other Lender and based on the financial statements
referred to in
<PAGE>   60
                                                                              56



Section 4.1 and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement.  Each Lender also acknowledges that it will, independently and
without reliance upon the Administrative Agent, the CAF Advance Agent or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

                 SECTION 8.5  Indemnification.  The Lenders agree to indemnify
the Administrative Agent and the CAF Advance Agent (to the extent not
reimbursed by the Borrowers), ratably according to the respective principal
amounts of the Notes then held by each of them (or if no Notes are at the time
outstanding or if any Notes are held by Persons which are not Lenders, ratably
according to the respective amounts of their aggregate Commitments), from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by, or asserted against the
Administrative Agent or the CAF Advance Agent in any way relating to or arising
out of this Agreement or any action taken or omitted by the Administrative
Agent or the CAF Advance Agent under this Agreement, provided that no Lender
shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting from the Administrative Agent's or the CAF Advance Agent's gross
negligence or willful misconduct.  Without limitation of the foregoing, each
Lender agrees to reimburse the Administrative Agent and the CAF Advance Agent
promptly upon demand for its ratable share of any out-of-pocket expenses
(including reasonable counsel fees) incurred by the Administrative Agent or the
CAF Advance Agent in connection with the preparation, execution, delivery,
administration, modification, amendment or enforcement (whether through
negotiations, legal proceedings, in bankruptcy or insolvency proceedings, or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, to the extent that the Administrative Agent or the CAF Advance
Agent is not reimbursed for such expenses by the Borrowers.

                 SECTION 8.6  Successor Administrative Agent and CAF Advance
Agent.  The Administrative Agent and the CAF Advance Agent may resign at any
time by giving written notice thereof to the Lenders and the Company and may be
removed at any time with or without cause by the Majority Lenders.  Upon any
such resignation or removal, the Majority Lenders shall have the right to
appoint a successor Administrative Agent or the CAF Advance Agent.  If no
successor Administrative Agent or CAF Advance Agent shall have been so
appointed by the Majority Lenders, and shall have accepted such appointment,
within 30 days after the retiring Administrative Agent's or the CAF Advance
Agent giving of notice of resignation or the Majority Lenders' removal of the
retiring Administrative Agent or CAF Advance Agent, then such retiring
<PAGE>   61
                                                                              57



Administrative Agent or CAF Advance Agent may, on behalf of the Lenders,
appoint a successor Administrative Agent or CAF Advance Agent, which shall be a
Lender and a commercial bank organized, or authorized to conduct a banking
business, under the laws of the United States of America or of any State
thereof and having a combined capital and surplus of at least $500,000,000.
Upon the acceptance of any appointment as Administrative Agent or CAF Advance
Agent hereunder by a successor Administrative Agent or CAF Advance Agent, such
successor Administrative Agent or CAF Advance Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent or CAF Advance Agent, and the retiring
Administrative Agent or CAF Advance Agent shall be discharged from its duties
and obligations under this Agreement.  After any retiring Administrative
Agent's or CAF Advance Agent's resignation or removal hereunder as
Administrative Agent or CAF Advance Agent, the provisions of this Article VII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Administrative Agent or CAF Advance Agent under this Agreement.


                                   ARTICLE IX

                 SECTION 9.1  Amendments, Etc.  An amendment or waiver of any
provision of this Agreement or the Notes, or a consent to any departure by any
Borrower therefrom, shall be effective against the Lenders and all holders of
the Notes if, but only if, it shall be in writing and signed by the Majority
Lenders, and then such a waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however, that no such amendment, waiver or consent shall, unless in writing and
signed by all the Lenders, be effective to:  (a) waive any of the conditions
specified in Article III, (b) increase the Commitments of the Lenders or
subject the Lenders to any additional obligations, (c) reduce the principal of,
or interest on, the Notes or any facility fees hereunder, (d) postpone any date

Agreement, (f) amend this Section 9.1 or (g) amend, waive or consent to any
departure of any provision in Article VI; provided, further, that no amendment,
waiver or consent shall, unless in writing and signed by the Administrative

to take such action, affect the rights or duties of the Administrative Agent or
the CAF Advance Agent under this Agreement or any Note.

good faith that it was given by an authorized representative of the applicable
Borrower and acts pursuant thereto, notwithstanding the absence of written
confirmation or any contradictory provision thereof.

                 SECTION 9.3  No Waiver; Remedies.  No failure on the part of
any Lender, the Administrative Agent or the CAF Advance Agent to exercise, and
no delay in exercising, any right hereunder or under any Note shall operate as
a waiver thereof; nor shall any single or partial exercise of any right
hereunder or under any Note preclude any other or further exercise thereof or

and not exclusive of any remedies provided by law.

                 SECTION 9.4  Costs and Expenses; Indemnity.  (a)  Each

out-of-pocket costs and expenses, if any, incurred by the Administrative Agent,
the CAF Advance Agent and the Lenders in connection with the enforcement
(whether through negotiations, legal proceedings in bankruptcy or insolvency

to be delivered hereunder and thereunder, including the reasonable fees and
out-of-pocket expenses of counsel.

                 (b)      If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance or CAF Advance is made by any Borrower to or for the
account of a Lender on any day other than the last day of the Interest Period
for such Advance, as a result of a prepayment pursuant to Section 2.15 or a
Conversion pursuant to Section 2.13(f) or Section 2.14 or due to acceleration
of the maturity of the Notes pursuant to Section 7.1 or due to any other reason
attributable to such Borrower, such Borrower shall, upon demand by such Lender
(with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender any amounts required to
compensate such Lender for any additional losses, costs or expenses which it
may reasonably incur as a result of such payment or Conversion, including,
without limitation, any loss (excluding loss of anticipated profits), cost or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by any Lender to fund or maintain such Advance.

                 (c)      Each Borrower agrees to indemnify and hold harmless
the Administrative Agent, the CAF Advance Agent and each Lender (to the extent
not reimbursed by any other Borrower) from and against any and all claims,
damages, liabilities and expenses (including, without limitation, fees and
disbursements of counsel) which may be incurred by or asserted against the
Administrative Agent, the CAF Advance Agent or such Lender in connection with
or arising out of any investigation, litigation, or proceeding (whether or not
the Administrative Agent, the CAF Advance Agent or such Lender is party
thereto) related to any acquisition or proposed acquisition by the Company, or
by any Subsidiary of the Company, of all or any portion of the stock or
substantially all the assets of any Person or any use or proposed use of the
Advances by any Borrower (excluding any claims, damages, liabilities or
expenses incurred by reason of the gross negligence or willful misconduct of
the party to be indemnified or its employees or agents, or by reason of any use
or disclosure of information relating to any such acquisition or use or
proposed use of the proceeds by the party to be indemnified or its employees or
agents).

Notes as due and payable pursuant to the provisions of Section 7.1, each Lender
is hereby authorized at any time and from time to time, to the fullest extent

indebtedness at any time owing by such Lender to or for the
<PAGE>   64
                                                                              60



credit or the account of the applicable Borrower against any and all of the
obligations of such Borrower now or hereafter existing under this Agreement and
the Notes of such Borrower held by such Lender, irrespective of whether or not
such Lender shall have made any demand under this Agreement or such Notes and
although such obligations may be unmatured.  Each Lender agrees promptly to
notify the Company after any such set-off and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of
such set-off and application.  The rights of each Lender under this Section 9.5
are in addition to other rights and remedies (including, without limitation,
other rights of set-off) which such Lender may have.

                 SECTION 9.6  Binding Effect.  This Agreement shall become
effective in accordance with the provisions of Section 3.1, and thereafter
shall be binding upon and inure to the benefit of the Borrowers, the
Administrative Agent, the CAF Advance Agent and each Lender and their
respective successors and assigns, except that no Borrower shall have the right
to assign its rights hereunder or any interest herein without the prior written
consent of all of the Lenders.

                 SECTION 9.7  Assignments and Participations.  (a)  Each Lender
may assign to one or more banks or other financial institutions all or a
portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitment, the Advances owing to it and
the Notes held by it); provided, however, that (i) each such assignment shall
be of a constant, and not a varying, percentage of all rights and obligations
under this Agreement, (ii) the amount of the Commitment of the assigning Lender
being assigned pursuant to each such assignment (determined as of the date of
the Assignment and Acceptance with respect to such assignment) shall in no
event be less than $15,000,000 (or, if less, the entire Commitment of the
assigning Lender) and shall be an integral multiple of $1,000,000, (iii) each
such assignment shall be to an Eligible Assignee, and (iv) the parties to each
such assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance,
together with any Notes subject to such assignment and a processing and
recordation fee of $2,500, and shall send to the Company an executed
counterpart of such Assignment and Acceptance.  Upon such execution, delivery,
acceptance and recording, from and after the effective date specified in each
Assignment and Acceptance, (A) the assignee thereunder shall be a party hereto
and, to the extent that rights and obligations hereunder have been assigned to
it pursuant to such Assignment and Acceptance, have the rights and obligations
of a Lender hereunder and (B) the assigning Lender thereunder shall, to the
extent that rights and obligations hereunder have been assigned by it pursuant
to such Assignment and Acceptance, relinquish its rights and be released from
its obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's
rights and
<PAGE>   65
                                                                              61



obligations under this Agreement, such Lender shall cease to be a party
hereto).

                 (b)      By executing and delivering an Assignment and
Acceptance, each Lender assignor thereunder and the assignee thereunder confirm
to and agree with each other and the other parties hereto as follows:  (i)
other than as provided in such Assignment and Acceptance, such assigning Lender
makes no representation or warranty and assumes no responsibility with respect
to any statements, warranties or representations made in or in connection with
this Agreement or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other instrument or
document furnished pursuant hereto; (ii) such assigning Lender makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of each Borrower or the performance or observance by each
Borrower of any of its obligations under this Agreement or any other instrument
or document furnished pursuant hereto; (iii) such assignee confirms that it has
received a copy of this Agreement, together with copies of the financial
statements referred to in Section 4.1 and such other documents and information
as it has deemed appropriate to make its own credit analysis and decision to
enter into such Assignment and Acceptance; (iv) such assignee will,
independently and without reliance upon the Administrative Agent, the CAF
Advance Agent, such assigning Lender or any other Lender and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement; (v) such assignee confirms that it is an Eligible Assignee; (vi)
such assignee appoints and authorizes the Administrative Agent and the CAF
Advance Agent to take such action as agent on its behalf and to exercise such
powers under this Agreement as are delegated to the Administrative Agent and
the CAF Advance Agent by the terms hereof, together with such powers as are
reasonably incidental thereto; and (vii) such assignee agrees that it will
perform in accordance with their terms all of the obligations which by the
terms of this Agreement are required to be performed by it as a Lender.

                 (c)      The Administrative Agent shall maintain at its
address referred to in Section 9.2 a copy of each Assignment and Acceptance
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lenders and the Commitment of, and principal amount of the
Advances owing to, each Lender from time to time (the "Register").  The entries
in the Register shall be conclusive and binding for all purposes, absent
manifest error, and each Borrower, the Administrative Agent, the CAF Advance
Agent and the Lenders may treat each Person whose name is recorded in the
Register as a Lender hereunder for all purposes of this Agreement.  The
Register shall be available for inspection by any Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.  Upon the
acceptance of any Assignment and Acceptance for
<PAGE>   66
                                                                              62



recordation in the Register, Schedule I hereto shall be deemed to be amended to
reflect the revised Commitments of the Lenders parties to such Assignment and
Acceptance as well as administrative information with respect to any new Lender
as such information is recorded in the Register.

                 (d)      Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and as assignee representing that it is an
Eligible Assignee, together with any Notes subject to such assignment, the
Administrative Agent shall, if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit G hereto, (i) accept such
Assignment and Acceptance, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Company; within five
Business Days after its receipt of such notice and its receipt of an executed
counterpart of such Assignment and Acceptance, the Borrowers, at their own
expense, shall execute and deliver to the Administrative Agent in exchange for
the surrendered Notes new Notes to the order of such Eligible Assignee in an
amount equal to the Commitment assumed by it pursuant to such Assignment and
Acceptance and, if the assigning Lender has retained a Commitment hereunder,
new Notes to the order of the assigning Lender in an amount equal to the
Commitment retained by it hereunder.  Such new Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Notes, shall be dated (A) in the case of Notes made by the Company, the Closing
Date and (B) in the case of Notes made by a Borrowing Subsidiary, the date such
Borrowing Subsidiary executes and delivers its Joinder Agreement, and shall
otherwise be in substantially the form of Exhibits A and C hereto.

                 (e)      Each Lender may sell participations to one or more
banks or other entities in or to all or a portion of its rights and obligations
under this Agreement (including, without limitation, all or a portion of its
Commitment, and the Advances owing to it and the Notes held by it); provided,
however, that (i) such Lender's obligations under this Agreement (including,
without limitation, its Commitment to the Borrowers hereunder) shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, (iii) such Lender shall
remain the holder of any such Notes for all purposes of this Agreement, (iv)
the Borrowers, the Administrative Agent, the CAF Advance Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement, (v)
such Lender shall continue to be able to agree to any modification or amendment
of this Agreement or any waiver hereunder without the consent, approval or vote
of any such participant or group of participants, other than modifications,
amendments and waivers which (A) postpone any date fixed for any payment of, or
reduce any payment of, principal of or interest on such Lender's Notes or any
facility fees payable under this Agreement, or (B) increase the amount of
<PAGE>   67
                                                                              63



such Lender's Commitment in a manner which would have the effect of increasing
the amount of a participant's participation, or (C) reduce the interest rate
payable under this Agreement and such Lender's Notes, or (D) consent to the
assignment or the transfer by any Borrower of any of its rights and obligations
under the Agreement, and (vi) except as contemplated by the immediately
preceding clause (v), no participant shall be deemed to be or to have any of
the rights or obligations of a "Lender" hereunder.

                 (f)      Any Lender may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.7, disclose to the assignee or participant or proposed assignee or
participant, any information relating to the Borrowers furnished to such Lender
by or on behalf of the Borrowers; provided that, prior to any such disclosure,
the assignee or participant or proposed assignee or participant shall agree in
writing for the benefit of the Borrowers to preserve the confidentiality of any
confidential information relating to the Borrowers received by it from such
Lender in a manner consistent with Section 9.8.

                 (g)      Anything in this Agreement to the contrary
notwithstanding, any Lender may at any time create a security interest in all
or any portion of its rights under this Agreement (including, without
limitation, the Advances owing to it) and the Notes issued to it hereunder in
favor of any Federal Reserve Bank in accordance with Regulation A of the Board
of Governors of the Federal Reserve System (or any successor regulation) and
the applicable operating circular of such Federal Reserve Bank.

                 SECTION 9.8  Confidentiality.  Each Lender, the Administrative
Agent and the CAF Advance Agent (each, a "Party") agrees that it will use its
best efforts not to disclose, without the prior consent of the Company (other
than to its, or its Affiliate's, employees, auditors, accountants, counsel or
other representatives, whether existing at the date of this Agreement or any
subsequent time), any information with respect to the Borrowers which is
furnished pursuant to this Agreement, provided that any Party may disclose any
such information (i) as has become generally available to the public, (ii) as
may be required or appropriate in any report, statement or testimony submitted
to any municipal, state or Federal regulatory body having or claiming to have
jurisdiction over such party or to the Board of Governors of the Federal
Reserve System or the Federal Deposit Insurance Corporation or similar
organizations (whether in the United States or elsewhere) or their successors,
(iii) as may be required or appropriate in response to any summons or subpoena
or in connection with any litigation or regulatory proceeding, (iv) in order to
comply with any law, order, regulation or ruling applicable to such party, or
(v) to any prospective assignee or participant in connection with any
contemplated assignment of any rights or obligations hereunder, or any sale of
any participation therein, by such Party pursuant to Section 9.7, if such
prospective assignee or participant, as the case may be, executes

an agreement with the Company containing provisions substantially similar to
those contained in this Section 9.8; provided, however, that the Company
acknowledges that the Administrative Agent has disclosed and may continue to
disclose such information as the Administrative Agent in its sole discretion
determines is appropriate to the Lenders from time to time.

                 SECTION 9.9  Consent to Jurisdiction.  (a)  Each Borrower
hereby irrevocably submits to the jurisdiction of any New York State or Federal
court sitting in New York City and any appellate court from any thereof in any
action or proceeding by the Administrative Agent, the CAF Advance Agent, any
Lender or the holder of any Note in respect of, but only in respect of, any
claims or causes of action arising out of or relating to this Agreement or the
Notes (such claims and causes of action, collectively, being "Permitted
Claims"), and each Borrower hereby irrevocably agrees that all Permitted Claims
may be heard and determined in such New York State court or in such Federal
court.  Each Borrower hereby irrevocably waives, to the fullest extent it may
effectively do so, the defense of an inconvenient forum to the maintenance of
such action or proceeding in any aforementioned court in respect of Permitted
Claims.  Each Borrower hereby irrevocably appoints CT Corporation System (the
"Process Agent"), with an office on the date hereof at 1633 Broadway, New York,
New York 10019, as its agent to receive on behalf of such Borrower and its
property service of copies of the summons and complaint and any other process
which may be served by the Administrative Agent, any Lender or the holder of
any Note in any such action or proceeding in any aforementioned court in
respect of Permitted Claims.  Such service may be made by delivering a copy of
such process to the Company by courier and by certified mail (return receipt
requested), fees and postage prepaid, both (i) in care of the Process Agent at
the Process Agent's above address and (ii) at the Company's address specified
pursuant to Section 9.2, and each Borrower hereby irrevocably authorizes and
directs the Process Agent to accept such service on its behalf.  Each Borrower
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by law.

                 (b)      Nothing in this Section 9.9 (i) shall affect the
right of any Lender, the holder of any Note or the Administrative Agent or the
CAF Advance Agent to serve legal process in any other manner permitted by law
or affect any right otherwise existing of any Lender, the holder of any Note or
the Administrative Agent or the CAF Advance Agent to bring any action or
proceeding against any Borrower or its property in the courts of other
jurisdictions or (ii) shall be deemed to be a general consent to jurisdiction
in any particular court or a general waiver of any defense or a consent to
jurisdiction of the courts expressly referred to in subsection (a) above in any
action or proceeding in respect of any claim or cause of action other than
Permitted Claims.

                 SECTION 9.10  GOVERNING LAW.  THIS AGREEMENT AND THE NOTES
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE
OF NEW YORK.

                 SECTION 9.11  Rate of Interest.  It is the intention of the
parties hereto that each Lender shall each conform strictly to usury laws
applicable to it.  Accordingly, if the transactions contemplated hereby would
be usurious as to any Lender under laws applicable to it, then, in that event,
notwithstanding anything to the contrary in this Agreement or in the Notes to
the order of such Lender, it is agreed as follows:  (a) the aggregate of all
consideration which constitutes interest under law applicable to such Lender
that is contracted for, taken, reserved, charged or received by such Lender
hereunder, or under such Notes or otherwise, shall under no circumstances
exceed the maximum amount allowed by such applicable law, and any excess shall
be credited by such Lender on the principal amount of the sums owed to such
Lender (or, if all amounts owing to such Lender shall have been paid in full,
refunded by such Lender to the applicable Borrower); or (b) in the event that a
prepayment of any Advances owed to any Lender is required, then such
consideration that constitutes interest under law applicable to such Lender may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for shall be cancelled automatically by such
Lender as of the date of such prepayment and, if theretofore paid, shall be
credited by such Lender on the principal amount of such prepayment obligation
(or, if the principal amount of such prepayment obligation shall have been paid
in full, refunded by such Lender to the applicable Borrower).  To the extent
that Article 5069-1.04 of the Texas Revised Civil Statutes is relevant to any
Lender for the purpose of determining the maximum amount of interest allowed by
applicable law, such Lender hereby elects to determine the applicable rate
ceiling under such Article by the indicated (weekly) rate ceiling from time to
time in effect, subject to such Lender's right subsequently to change such
method in accordance with applicable law.  In no event, however, shall Article
5069, Chapter 15, of the Texas Revised Civil Statutes apply to this Agreement
or the Notes or the transactions contemplated hereby.

                 SECTION 9.12  Execution in Counterparts.  This Agreement may
be executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.  Delivery to the Administrative Agent of a counterpart executed by a
Lender shall constitute delivery of such counterpart to all of the Lenders.
This Agreement may be delivered by facsimile transmission of the relevant
signature pages hereof.

                 IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be executed by their respective officers thereunto duly
authorized, as of the date first above written.

         FOR VALUE RECEIVED, the undersigned, ___________________, a ________
corporation (the "Borrower"), hereby unconditionally promises to pay to the
order of                  (the "Lender") at the office of Chemical Bank,
located at 270 Park Avenue, New York, New York 10017, in lawful money of the
United States of America and in same day funds, on the Termination Date the
principal amount of (a)                  DOLLARS ($          ), or, if less,
(b) the aggregate unpaid principal amount of all Revolving Credit Advances made
by the Lender to the Borrower pursuant to subsection 2.1 of the Credit
Agreement, as hereinafter defined.  The Borrower further agrees to pay interest
in like money at such office on the unpaid principal amount hereof from time to

payment or prepayment of principal thereof, each continuation thereof, each
conversion of all or a portion thereof to another Type and, in the case of
Eurodollar Rate Advances, the length of each Interest Period with respect
thereto.  Each such endorsement shall constitute prima facie evidence of the
accuracy of the information endorsed.  The failure to make any such endorsement
shall not affect the obligations of the Borrower in respect of such Revolving
Credit Advance.

         This Note (a) is one of the Revolving Credit Notes referred to in the
Revolving Credit and Competitive Advance Facility Agreement, dated as of August
10, 1994 (as amended, supplemented or otherwise modified from time to time, the

         FOR VALUE RECEIVED, the undersigned,                           , 
a ________ corporation (the "Borrower"), hereby unconditionally promises 
to pay to the order of             (the "Lender") at the office of Chemical Bank

hereinafter defined.  The principal amount of each CAF Advance evidenced hereby
shall be payable on the maturity date therefor set forth on the schedule
attached hereto and made a part hereof or on a continuation of such schedule
which shall be attached hereto and made a part hereof (the "Grid").  The
Borrower further agrees to pay interest in like money at such office on the
unpaid principal amount of each CAF Advance evidenced hereby, at the rate per

endorsement shall not affect the obligations of the Borrower in respect of such
CAF Advance.

         This Note is one of the CAF Advance Notes referred to in the Revolving
Credit and Competitive Advance Facility Agreement, dated as of August 10, 1994

                           ASSIGNMENT AND ACCEPTANCE

                           Dated _____________, 19__

                 1.       The Assignor hereby sells and assigns to the
Assignee, and the Assignee hereby purchases and assumes from the Assignor, that

specified on Schedule 1 of all outstanding rights and obligations under the

exchange such Notes for new Notes payable to the order of the Assignee in an
amount equal to the Commitment assumed by the Assignee pursuant hereto or new
Notes payable to the order of the Assignee in an amount equal to the

Commitment assumed by the Assignee pursuant hereto and the Assignor in an

referred to in Section 4.1 thereof and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into this Assignment and Acceptance; (ii) agrees that it will, independently
and without reliance upon the Administrative Agent, the Assignor or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under the Credit Agreement; (iii) confirms that it is an Eligible
Assignee; (iv) appoints and authorizes the Administrative Agent and CAF Advance
Agent to take such action as agent on its behalf and to exercise such powers
under the Credit Agreement as are delegated to the Administrative Agent and CAF
Advance Agent by the terms thereof, together with such powers as are reasonably
incidental thereto; (v) agrees that it will perform in accordance with their
terms all of the obligations which by the terms of the Credit Agreement are
required to be performed by it as a Lender; (and) (vi) specifies as its address
for notices the address set forth beneath its name on the signature pages
hereof (and (vii) attaches the forms prescribed by the Internal Revenue Service
of the United States certifying as to the Assignee's status for purposes of
determining exemption from United States withholding taxes with respect to all
payments to be made to the Assignee under the Credit Agreement and the Notes or
such other documents as are necessary to indicate that all such payments are
subject to such rates at a rate reduced by an applicable tax treaty)*.

                 4.       Following the execution of this Assignment and
Acceptance by the Assignor and the Assignee, it will be delivered to the
Administrative Agent for acceptance and recording by the Administrative Agent.
The effective date of this Assignment and Acceptance shall be the date of
acceptance thereof by the Administrative Agent, unless otherwise specified on
Schedule 1 hereto (the "Effective Date").

                 5.       Upon such acceptance and recording by the
Administrative Agent, as of the Effective Date, (i) the Assignee shall be a
party to the Credit Agreement and, to the extent provided in this Assignment
and Acceptance, have the rights and obligations of Lender thereunder and (ii)

                        Re:  El Paso Natural Gas Company

Ladies and Gentlemen:

                 This opinion is furnished to you pursuant to Section 3.1(d) of
the Revolving Credit and Competitive Advance Facility Agreement, dated as of
August 10, 1994 (the "Credit Agreement"), among El Paso Natural Gas Company
(the "Borrower"), the banks and other financial institutions from time to time
party thereto (each a "Lender," and together the "Lenders"), and Chemical Bank,
as Administrative Agent (in such capacity, the "Administrative Agent") and as
CAF Advance Agent (in such capacity, the "CAF Advance Agent") for the Lenders.
Unless the context otherwise requires, all capitalized terms used herein
without definition shall have the meanings ascribed to them in the Credit
Agreement.

                I am [Associate] General Counsel of the Borrower, and I, or
attorneys over whom I exercise supervision, have acted as counsel for the
Borrower in connection with the preparation, execution and delivery of the
Credit Agreement.  In that connection, I or such attorneys have examined:

               (1)  the Credit Agreement, executed by the parties
       thereto;

               (2)  the Notes, executed by the Borrower; and

               (3)  the other documents furnished by the Borrower
       pursuant to Section 3.1 of the Credit Agreement.

                 I, or attorneys over whom I exercise supervision, have also
examined the originals, or copies certified to our satisfaction, of the
agreements, instruments and other documents, and all of the orders, writs,
judgments, awards, injunctions and decrees, which affect or purport to affect
the Borrower's ability to perform the Borrower's obligations under the Credit
Agreement or the Notes (collectively referred to herein as the "Documents").
In addition, I, or attorneys over whom I exercise supervision, have examined
the originals, or copies certified to
<PAGE>   94
                                                                             H-2

our satisfaction, of such other corporate records of the Borrower, certificates
of public officials and of officers of the Borrower, and agreements,
instruments and other documents, as I have deemed necessary as a basis for the
opinions hereinafter expressed.  In all such examinations, I, or attorneys over
whom I exercise supervision, have assumed the legal capacity of all natural
persons executing documents, the genuineness of all signatures on original or
certified, conformed or reproduction copies of documents of all parties (other
than, with respect to the Documents, the Borrower), the authenticity of
original and certified documents and the conformity to original or certified
copies of all copies submitted to such attorneys or me as conformed or
reproduction copies.  As to various questions of fact relevant to the opinions
expressed herein, I have relied upon, and assume the accuracy of,
representations and warranties contained in the Credit Agreement and
certificates and oral or written statements and other information of or from
public officials, officers and/or representatives of the Borrower and others.

                 I have assumed that the parties to the Documents other than
the Borrower have the power to enter into and perform such documents and that
such documents have been duly authorized, executed and delivered by, and
constitute legal, valid and binding obligations of, such parties.

                 The opinions expressed below are limited to the federal laws
of the United States and the laws of the State of Texas and, to the extent
relevant hereto, the General Corporation Law of the State of Delaware, as
currently in effect.  I assume no obligation to supplement this opinion if any
applicable laws change after the date hereof or if I become aware of any facts
that might change the opinions expressed herein after the date hereof.

                 Based on the foregoing and upon such investigation as we have
deemed necessary, and subject to the limitations, qualifications and
assumptions set forth herein, I am of the following opinion:

                 1.       The Borrower (i) is a corporation duly incorporated
         and existing in good standing under the laws of the State of Delaware,
         and (ii) possesses all the corporate powers and all other
         authorizations and licenses necessary to engage in its business and
         operations as now conducted, the failure to obtain or maintain which
         would have a Material Adverse Effect.

                 2.       The execution, delivery and performance by the
         Borrower of the Documents are within the Borrower's corporate powers
         and have been duly authorized by all necessary corporate action in
         respect of or by the Borrower, and do not contravene (i) the
         Borrower's charter or by-laws, each as amended to date, (ii) any Texas
         or federal law, rule or regulation applicable to the Borrower
         (excluding provisions of federal law expressly referred to in and
<PAGE>   95
                                                                             H-3

         covered by the opinion of Fried, Frank, Harris, Shriver & Jacobson
         delivered to you in connection with the transactions contemplated
         hereby), or (iii) any contractual restriction binding on or affecting
         the Borrower.  The Documents have been duly executed and delivered on
         behalf of the Borrower.

                 3.       No authorization or approval or other action by, and
         no notice to or filing with, any Texas or federal governmental
         authority or regulatory body (including, without limitation, the FERC)
         is required for the due execution, delivery and performance by the
         Borrower of the Documents, except those required in the ordinary
         course of business in connection with the performance by the Borrower
         of its obligations under certain covenants and warranties contained in
         the Documents.

                 4.       To the best of my knowledge, there is no action, suit
         or proceeding pending or overtly threatened against or involving the
         Borrower or any of the Principal Subsidiaries which, in my reasonable
         judgment (taking into account the exhaustion of all appeals), would
         have a material adverse effect upon the consolidated financial
         condition of the Borrower and its consolidated Subsidiaries taken as a
         whole, or which purports to affect the legality, validity, binding
         effect or enforceability of any Document.

                 These opinions are given as of the date hereof and are solely
for your benefit in connection with the transactions contemplated by the Credit
Agreement.  These opinions may not be relied upon by you for any other purpose
or relied upon by any other person for any purpose without my prior written
consent.


                                                            Very truly yours,

                FORM OF OPINION OF FRIED FRANK, HARRIS, SHRIVER
                  & JACOBSON, NEW YORK COUNSEL TO THE COMPANY




__________ __, 1994


To Each of the Lenders, the Administrative Agent
  and the CAF Advance Agent
  Referred to Below
c/o Chemical Bank
270 Park Avenue
New York, New York  10017

Ladies and Gentlemen:

                 We have acted as special New York counsel for El Paso Natural
Gas Company, a Delaware corporation (the "Borrower"), in connection with the
Revolving Credit and Competitive Advance Facility Agreement, dated as of August
10, 1994 (the "Credit Agreement"), among the Borrower, the banks and other
financial institutions from time to time party thereto (each a "Lender," and
together the "Lenders"), and Chemical Bank, as Administrative Agent (in such
capacity, the "Administrative Agent") and as CAF Advance Agent (in such
capacity, the "CAF Advance Agent") for the Lenders.  This opinion is delivered
to you pursuant to Section 3.1(e) of the Credit Agreement.  All capitalized
terms used herein that are defined in, or by reference in, the Credit Agreement
have the meanings assigned to such terms therein, or by reference therein,
unless otherwise defined herein.  With your permission, all assumptions and
statements of reliance herein have been made without any independent
investigation or verification on our part except to the extent otherwise
expressly stated, and we express no opinion with respect to the subject matter
or accuracy of such assumptions or items relied upon.

                 In connection with this opinion, we have (i) investigated such
questions of law, (ii) examined originals or certified, conformed or
reproduction copies of such documents, and (iii) received such information from
officers and representatives of the Borrower as we have deemed necessary or
appropriate for the purposes of this opinion.  We have examined, among other
documents, the following:

                 (a)      an executed copy of the Credit Agreement; and

                 (b)      an executed copy of each of the Notes.

The documents referred to in items (a) and (b) above are referred to herein
collectively as the "Documents."
<PAGE>   97
                                                                             I-2


                 In all such examinations, we have assumed the legal capacity
of all natural persons executing documents, the genuineness of all signatures
on original or certified, conformed or reproduction copies of documents of all
parties, the authenticity of original and certified documents and the
conformity to original or certified copies of all copies submitted to us as
conformed or reproduction copies.  As to various questions of fact relevant to
the opinions expressed herein, we have relied upon, and assume the accuracy of,
representations and warranties contained in the Documents and certificates and
oral or written statements and other information of or from representatives of
the Borrower and others.  With respect to the opinions expressed in paragraph
(a) below, our opinions are limited (x) to our actual knowledge of the
Borrower's specially regulated business activities and properties based solely
upon an officer's certificate in respect of such matters and without any
independent investigation or verification on our part and (y) to our review of
only those laws and regulations that, in our experience, are normally
applicable to transactions of the type contemplated by the Documents.

                 To the extent it may be relevant to the opinions expressed
herein, we have assumed that the parties to the Documents other than the
Borrower have the power to enter into and perform such documents and that such
documents have been duly authorized, executed and delivered by, and constitute
legal, valid and binding obligations of, such parties.

                 Based upon the foregoing, and subject to the limitations,
qualifications and assumptions set forth herein, we are of the opinion that:

                 (a)      The execution and delivery to the Administrative
         Agent, the CAF Advance Agent and the Lenders by the Borrower of the
         Documents and the performance by the Borrower of its obligations
         thereunder (i) do not require under present law, any filing or
         registration by the Borrower with, or approval or consent to the
         Borrower of, any governmental agency or authority of the State of New
         York, except those, if any, required in the ordinary course of
         business in connection with the performance by the Borrower of its
         obligations under certain covenants and warranties contained in the
         Documents and (ii) do not violate any present law, or present
         regulation of any governmental agency or authority, of the State of
         New York applicable to the Borrower or its property.

                 (b)      The Documents constitute the legal, valid and binding
         obligations of the Borrower enforceable against the Borrower in
         accordance with their respective terms.

                 (c)      The borrowings by the Borrower under the Credit
         Agreement and the applications of the proceeds thereof as provided in
         the Credit Agreement will not violate Regulation G, T, U or X of the
         Board of Governors of the Federal Reserve System.

                                                                             I-3


                 The opinions set forth above are subject to the following
qualifications:

                 (A)       We express no opinion as to:

                          (i)     the validity, binding effect or
                 enforceability (a) of any provision of the Documents relating
                 to indemnification, contribution or exculpation in connection
                 with violations of any securities laws or statutory duties or
                 public policy, or in connection with willful, reckless or
                 criminal acts or gross negligence of the indemnified or
                 exculpated party or the party receiving contribution; or (b)
                 of any provision of any of the Documents relating to
                 exculpation of any party in connection with its own negligence
                 that a court would determine in the circumstances under
                 applicable law to be unfair or insufficiently explicit;

                            (ii)  the validity, binding effect or
                 enforceability of (a) any purported waiver, release,
                 variation, disclaimer, consent or other agreement to similar
                 effect (all of the foregoing, collectively, a "Waiver") by the
                 Borrower under the Documents to the extent limited by
                 provisions of applicable law (including judicial decisions),
                 or to the extent that such a Waiver applies to a right, claim,

                 occurring as a matter of law (including judicial decisions),
                 except to the extent that such a Waiver is effective under and
                 is not prohibited by or void or invalid under provisions of
                 applicable law (including judicial decisions) or (b) any
                 provision of any Document relating to choice of governing law
                 to the extent that the validity, binding effect or
                 enforceability of any such provision is to be determined by
                 any court other than a court of the State of New York;

                           (iii)  the enforceability of any provision in the
                 Documents specifying that provisions thereof may be waived
                 only in writing, to the extent that an oral agreement or an
                 implied agreement by trade practice or course of conduct has
                 been created that modifies any provision of the Documents;

                            (iv)  the effect of any law of any jurisdiction
                 other than the State of New York wherein the Administrative
                 Agent, the CAF Advance Agent or any Lender may be located or
                 wherein enforcement of any document referred to above may be
                 sought that limits the rates of interest legally chargeable or
                 collectible; and

                             (v)  any approval, consent or authorization of the
                 FERC or any other United States federal agency or authority
                 needed in connection with the execution,

                 delivery and performance by the Borrower of the Documents, the
                 consummation of the transactions contemplated thereby and
                 compliance with the terms and conditions thereof.

                 (B)      Our opinions above are subject to (i) applicable
         bankruptcy, insolvency, reorganization, moratorium, fraudulent
         transfer or similar laws from time to time in effect affecting
         creditors' rights generally, (ii) general principles of equity
         (including, without limitation, standards of materiality, good faith,
         fair dealing and reasonableness), whether such principles are
         considered in a proceeding at law or in equity and (iii) the
         qualification that certain other provisions of the Documents may be
         unenforceable in whole or in part under the laws (including judicial
         decisions) of the State of New York or the United States of America,
         but the inclusion of such provisions does not affect the validity as
         against the Borrower of the Documents as a whole, and the Documents
         contain adequate provisions for enforcing payment of the obligations
         governed thereby, subject to the other qualifications contained in
         this letter.

                 (C)      For purposes of the opinions set forth in paragraph
         (c) above, we have assumed that (i) none of the Administrative Agent,
         the CAF Advance Agent or any of the Lenders has or will have the
         benefit of any agreement or arrangement (excluding the Documents)
         pursuant to which any Advances are directly or indirectly secured by
         Margin Stock, (ii) none of the Administrative Agent, the CAF Advance
         Agent, any of the Lenders or any of their respective affiliates has
         extended or will extend any other credit to the Borrower directly or
         indirectly secured by Margin Stock and (iii) none of the
         Administrative Agent, the CAF Advance Agent or any of the Lenders has
         relied or will rely upon any Margin Stock as collateral in extending
         or maintaining any Advances pursuant to the Credit Agreement.

                 (D)      For purposes of our opinions above, insofar as they
         relate to the Borrower, we have assumed that (i) the Borrower is a
         corporation validly existing in good standing in its jurisdiction of
         incorporation, has all requisite power and authority, and has obtained
         all requisite corporate, shareholder, third party and governmental
         authorizations, consents and approvals, and made all requisite filings
         and registrations, necessary to execute, deliver and perform the
         Documents (except to the extent noted in paragraph (a) above), and
         that such execution, delivery and performance will not violate or
         conflict with any law, rule, regulation, order, decree, judgment,
         instrument or agreement binding upon or applicable to the Borrower or
         its properties (except to the extent noted in paragraph (a) above),
         and (ii) the Documents have been duly executed and delivered by the
         Borrower.

                 The opinions expressed herein are limited to the federal laws

                         FORM OF OPINION OF (ASSOCIATE)
                         GENERAL COUNSEL OF THE COMPANY


                 (a)      Each of the Company and the Borrowing Subsidiary (i)
         is a corporation duly incorporated and existing in good standing under
         the laws of the jurisdiction of its organization, and (ii) possesses
         all the corporate powers and all other authorizations and licenses
         necessary to engage in its business and operations as now conducted,
         the failure to obtain or maintain which would have a Material Adverse
         Effect.

                 (b)      The execution and delivery by the Company and the
         Borrowing Subsidiary of the Joinder Agreement and by the Borrowing
         Subsidiary of the Notes made by it and the performance by the
         Borrowing Subsidiary of its obligations as a "Borrowing Subsidiary"
         under the Credit Agreement and the Notes made by it are within such
         corporation's corporate powers and have been duly authorized by all
         necessary corporate action in respect of or by each of the Company and
         the Borrowing Subsidiary (as applicable), and do not contravene (i)
         the Company's or the Borrowing Subsidiary's charter or by-laws, each
         as amended to date, (ii) any Texas or federal law, rule or regulation
         applicable to the Company or the Borrowing Subsidiary (excluding
         provisions of federal law expressly referred to in and covered by the
         opinion of (New York Counsel) delivered to you in connection with the
         transactions contemplated hereby), or (iii) any contractual
         restriction binding on or affecting the Company or the Borrowing
         Subsidiary.  The Joinder Agreement has been duly executed and
         delivered on behalf of the Company and the Borrowing Subsidiary and
         the Notes made by the Borrowing Subsidiary have been duly executed and
         delivered on behalf of the Borrowing Subsidiary.

                 (c)      No authorization or approval or other action by, and
         no notice to or filing with, any Texas or federal governmental
         authority or regulatory body (including, without limitation, the FERC)
         is required for the due execution and delivery by the Company or the
         Borrowing Subsidiary of the Joinder Agreement, the performance by the
         Borrowing Subsidiary of its obligations as a "Borrowing Subsidiary"
         under the Credit Agreement and by the execution, delivery and
         performance of the Notes made by the Borrowing Subsidiary, except
         those required in the ordinary course of business in connection with
         the performance by the Company or the Borrowing Subsidiary of its
         obligations under certain covenants and warranties contained in the
         Joinder Agreement, the Credit Agreement and the Notes.

                 (d)      To the best of my best knowledge, there is no action,
         suit or proceeding pending or overtly threatened against or involving
         the Company or any of the Principal Subsidiaries which, in my
         reasonable judgment (taking into account the exhaustion of all
         appeals), would have a material adverse effect upon the consolidated
         financial condition of the Company and its consolidated Subsidiaries
         taken as a whole, or which purports to affect the legality, validity,
         binding effect or enforceability of the Joinder Agreement, the Credit
         Agreement or the Notes.

                          FORM OF OPINION OF NEW YORK
                             COUNSEL TO THE COMPANY


                 (a)      The execution and delivery to the Administrative
         Agent, the CAF Advance Agent and the Lenders by the Company and the
         Borrowing Subsidiary of the Joinder Agreement and by the Borrowing
         Subsidiary of the Notes made by it and the performance by the
         Borrowing Subsidiary of its obligations as a "Borrowing Subsidiary"
         under the Credit Agreement and the Notes made by it (i) do not require
         under present law, any filing or registration by the Company or the
         Borrowing Subsidiary with, or approval or consent to the Company or
         the Borrowing Subsidiary of, any governmental agency or authority of
         the State of New York or the State of Delaware, except those, if any,
         required in the ordinary course of business in connection with the
         performance by the Company or the Borrowing Subsidiary of their
         respective obligations under certain covenants and warranties
         contained in the Joinder Agreement, the Credit Agreement and the
         Notes, (ii) do not violate any present law, or present regulation of
         any governmental agency or authority, of the State of New York

         Corporation Law of the State of Delaware, or present regulation of any
         governmental agency or authority, of the State of Delaware applicable

                 (b)      The Joinder Agreement, the Credit Agreement and the
         Notes (as applicable) constitute the legal, valid and binding
         obligations of each of the Company and the Borrowing Subsidiary
         enforceable against each of the Company and the Borrowing Subsidiary
         in accordance with their respective terms.

                 (c)      The borrowings by the Borrowing Subsidiary under the
         Credit Agreement and the applications of the proceeds thereof as
         provided in the Credit Agreement will not violate Regulation G, T, U
         or X of the Board of Governors of the Federal Reserve System.
