ITEM 1.  BUSINESS

GENERAL

      Tejas Gas Corporation ("Tejas") is a major intrastate natural gas pipeline
company engaged in the business of purchasing, gathering, processing, treating,
storing, transporting and marketing natural gas. Tejas' operations are situated
primarily in the major gas producing areas in Oklahoma, South Texas, East Texas
and the Texas and Louisiana Gulf Coast regions, with additional facilities
located in West Virginia. Tejas is a holding company that conducts operations
through four principal second tier subsidiaries, Tejas Gas Corp. ("Tejas Gas"),
Acadian Gas Corporation ("Acadian"), Tejas Natural Gas Company ("TNGC") and,
since June 1996, Transok, Inc. ("Transok"). Tejas-Acadian Holding Company
("TAHC"), a wholly owned first tier subsidiary of Tejas, was organized in
December 1994 and owns the capital stock of each of Tejas Gas, Acadian and TNGC.
Tejas Transok Holding Company ("TTHC"), a wholly owned first tier subsidiary of
Tejas, was organized in May 1996 and owns the capital stock of Transok (see
"SIGNIFICANT ACQUISITION IN 1996" as described in this Item 1.). Tejas Coral
Holding Company ("TCHC"), formerly Tejas Alliance Holding Company, a wholly
owned first tier subsidiary of Tejas, was organized in July 1995 to hold an
interest in Coral Energy, L.P. ("Coral", formerly Coral Energy Resources, L.P.)
an energy marketing joint venture with Shell Oil Company ("Shell"). Unless the
context indicates otherwise, the term "Tejas" includes TAHC, TCHC and TTHC and
their respective subsidiaries.

      Tejas, a Delaware corporation, was organized on September 16, 1988 by
Hamilton Oil Corporation ("HOC") for the purpose of holding the capital stock of
Tejas Gas, which had been an indirect, wholly owned subsidiary of HOC or its
predecessor since 1979. Tejas Gas has been engaged in natural gas pipeline
operations and related activities since its inception in 1967. On July 1, 1988,
Tejas Gas purchased all of the outstanding capital stock of Gulf Energy Holding,
Inc. another company engaged through subsidiaries in natural gas pipeline
operations, principally in Texas. On December 27, 1988, Tejas' capital stock was
distributed to the stockholders of HOC in the form of a spin-off. On December
28, 1990, Tejas purchased through a wholly owned subsidiary, Acadian, all of the
capital stock of several corporations comprising the Acadian Gas Group, a group
of companies engaged in natural gas pipeline operations, principally in
Louisiana. On September 15, 1993, Tejas, through a wholly owned subsidiary,
TNGC, acquired from Exxon Corporation ("Exxon") substantially all of Exxon's
Texas and Louisiana intrastate natural gas pipeline operations as well as a
significant natural gas storage facility. Tejas, through subsidiaries of TCHC,
holds a one-half interest in Coral, an energy marketing venture between Tejas
and Shell which commenced operations in November 1995. Coral is a Delaware
limited partnership formed in September 1995 to market natural gas and power for
Tejas and Shell. Prior to January 1997, Coral was owned one-third by
subsidiaries of Tejas and two-thirds by subsidiaries of Shell. Effective January
1997, Tejas purchased from Shell an additional 16 2/3% interest in Coral thereby
increasing its ownership to 50%. Shell Canada Limited of Calgary, Alberta may
acquire an equity interest in Coral in a transaction expected to close in early
1997. This should enhance Coral's ability to expand its operations into Canada.

      On June 6, 1996, Tejas, through a newly formed wholly owned subsidiary,
TTHC, acquired from Central and South West Corporation ("CSW") Transok's
intrastate natural gas pipeline operations in Oklahoma, Texas and Louisiana and
a natural gas processing plant and storage facility, both located in Oklahoma.
In connection with the acquisition, Tejas entered into agreements to lease and
operate Transok's seven remaining natural gas processing plants in Oklahoma. See
"SIGNIFICANT ACQUISITION IN 1996" as described in this Item 1.

                                        2
<PAGE>
      Tejas is one of the largest independent intrastate gatherers and
transporters of natural gas volumes through company-owned pipelines in the
United States. During 1996, Tejas had an average throughput of 4.3 billion cubic
feet ("Bcf") of natural gas per day through its natural gas sales,
transportation and processing activities. In 1996, Tejas' core business of
purchasing, storing, selling, gathering and transporting natural gas through its
pipeline systems accounted for approximately 95% of its throughput and 82% of
gross profit, with the balance attributable to natural gas processing, treating
and off-system marketing.

      The executive offices of Tejas are at 1301 McKinney, Suite 700, Houston,
Texas 77010, and its telephone number is (713) 658-0509.

SIGNIFICANT ACQUISITION IN 1996

      On June 6, 1996, Tejas acquired Transok (the "Transok acquisition") from
CSW through a merger of a recently formed wholly owned subsidiary of Tejas into
Transok. Immediately prior to the acquisition, CSW sold seven natural gas
processing plants (the "Transok Plants") to a third party lessor (the "Lessor"),
which in turn leased these facilities (the "Lease") to a subsidiary of Tejas
(the "Lessee").

      Transok operates intrastate natural gas pipeline systems in Oklahoma,
Louisiana and Texas and is one of the largest processors of natural gas in
Oklahoma. At the time of the acquisition, Transok's operations included: (i)
approximately 7,000 miles of gathering and transmission pipelines in Oklahoma,
Louisiana and Texas with 2.3 Bcf of natural gas per day of pipeline capacity;
(ii) eight natural gas processing plants, of which seven are being leased to a
subsidiary of Tejas, with total processing capacity of 564 million cubic feet
("MMcf") per day of natural gas; (iii) a 26 Bcf capacity natural gas reservoir
storage facility with 300 MMcf per day of withdrawal and 200 MMcf per day of
injection capacity; and (iv) 1.4 trillion cubic feet of connected third-party
natural gas reserves. As described below, Tejas subsequently sold approximately
2,100 miles of gathering and transmission lines and a processing plant acquired
in the Transok acquisition.

      The total purchase price received by CSW at closing was $690 million in
cash, of which $565 million was paid by Tejas and $125 million was paid by the
Lessor to acquire the Transok Plants. In addition, as part of the transaction,
Transok retained $200 million of long-term debt. To finance the cash
requirements for the Transok acquisition, Tejas borrowed (i) $178 million under
its existing credit facilities and (ii) $387 million, net of a $38 million
voluntary prepayment, under a new $425 million credit agreement (the "Transok
Credit Facility"). The outstanding balance under the Transok Credit Facility was
reduced to approximately $196 million by year-end 1996 primarily due to the
application of proceeds received by Tejas subsequent to the Transok acquisition
from the sale of common stock (see Note 12 of "Notes to Consolidated Financial
Statements") and the sale of certain non-strategic assets (see Note 3 of "Notes
to Consolidated Financial Statements"). Prior to year-end, the Transok Credit
Facility was amended (the "Amended Transok Credit Facility"). The principal
changes included extending the maturity date from December 31, 1997 to December
31, 2004, lowering the interest rate margins over the London Interbank Offered
Rate ("LIBOR"), subject to a minimum margin for a limited period of time, and
setting the commitment amount at $275 million. The Amended Transok Credit
Facility bears interest, at Tejas' option, based upon either the prime rate or
LIBOR. Depending upon Transok's funded debt to capitalization ratio, the margins
over LIBOR that Transok must pay vary from a minimum of 0.5% to a maximum of
1.25%. Based upon the December 31, 1996 outstanding balance of approximately
$196 million, the Amended Transok Credit Facility had available borrowings of
approximately $79 million and bore interest, at Tejas' option, of prime or LIBOR
plus 1.0%. Under the terms of the Amended Transok Credit Facility, after two
years, the revolver will, unless extended at the option of the lenders, convert
into a six year reducing revolver. Unless extended, commitment reductions of
approximately $8.6 million per quarter will begin March 31, 1999 with the final
remaining commitment reduction to occur on December 31, 2004.

                                        3
<PAGE>
Nevertheless, based upon the current terms of the Amended Transok Credit
Facility and the outstanding principal balance thereunder at December 31, 1996,
no principal payments are required until 2001.

      In connection with the acquisition of Transok, CSW sold seven natural gas
processing plants to the Lessor for $125 million. Tejas, through a wholly owned
subsidiary, leased the Transok Plants from the Lessor for a five-year term with
lease payments adjusted quarterly based upon the Lessor's financing costs. Tejas
has entered into interest rate derivative agreements in a notional amount of
$125 million to hedge the effects of such adjustments on the required minimum
lease payments. In addition, under the Lease, the Lessee has the option to
extend the term of the Lease for up to two additional two year periods, subject
to approval by the Lessor, and to purchase all of the Transok Plants at any time
for $125 million. If by the end of the Lease term the Lessee has not exercised
its option to purchase all of the Transok Plants, it is obligated to pay the
Lessor a termination fee of approximately $106 million. However, the Lease
contains a provision that reduces the termination fee to the extent the proceeds
from the Lessor's subsequent sale of the Transok Plants exceed $19 million. The
Lease also provides the Lessee the option to purchase, at any time during the
Lease term, one or more of the Transok Plants for an aggregate amount not
exceeding $31 million, with corresponding reductions to the $106 million
termination fee and the $19 million threshold amount.

      The acquisition of Transok was accounted for as a purchase and the
purchase price was allocated to the acquired assets and liabilities based upon
the estimated fair value of such assets and liabilities as of June 6, 1996. The
Lease is for a five-year term and is accounted for as an operating lease. The
allocation of the purchase price is preliminary, as valuation and other studies
have not been finalized. It is not expected that the final allocation of the
purchase price will produce materially different results from those presented
herein. The results of operations for the assets acquired or leased as a result
of the Transok acquisition are included in the accompanying financial statements
for the period subsequent to June 6, 1996.

      During the last quarter of 1996, Tejas completed sales of three
non-strategic assets: a transmission and gathering system located in Northern
Louisiana, a processing plant and its related gathering system in North Central
Oklahoma and an interest in a partnership which owned and operated oil and gas
wells in Western Oklahoma. These transactions, none of which resulted in a gain
or loss, generated cash proceeds of approximately $110 million, most of which
were used to reduce the commitment level and repay indebtedness under the
Transok Credit Facility.

      Tejas' natural gas pipelines consist of main lines, lateral lines and
gathering lines which are located within the states of Texas, Oklahoma and
Louisiana, including offshore state waters in Texas. Tejas' pipeline operations
involve gathering and purchasing natural gas from producers and suppliers and
transporting and reselling, through Coral, such natural gas to electric utility
companies, local distribution companies, industrial customers, affiliates of
other pipeline companies, and gas marketing companies as well as transporting
and gathering natural gas for others on a fee basis. Tejas' natural gas pipeline
operations also include natural gas compression and dehydration. Natural gas is
received at numerous interconnections with natural gas producers' facilities and
from third-party pipelines and delivered to customers' facilities and markets in
other areas.

      Tejas' natural gas pipeline systems are substantially all located on
properties owned by others. Tejas has obtained easements or rights-of-way for
its natural gas pipeline systems which generally provide for perpetual
possession and use. In certain instances, periodic payments are required to be
made. Where believed required, permits and licenses have been obtained for
natural gas pipeline systems crossing or adjacent to public properties.
Certain easements have been acquired through eminent domain proceedings.

      Tejas' pipelines in Texas extend from South Texas near the Mexican border
along the Texas Gulf Coast to the Louisiana border and north from near Houston
to the East Texas producing areas. In addition, Tejas has a system that
traverses the West Texas producing areas and extends north to the Oklahoma
border and a system in the Fort Worth Basin. Tejas' Texas facilities consist of
gathering and transmission pipeline ranging in size from 2 to 36 inches in
diameter. The Texas facilities include three joint venture systems in South
Texas, a partnership system along the Texas Gulf Coast which is operated by
Tejas and a 508 mile leased system in East Texas. The Oklahoma system consists
of 2 to 30 inch diameter gathering and transmission lines extending throughout
the state excluding the panhandle area and provides Tejas access to an abundant
supply of natural gas reserves. Among other producing regions in Oklahoma,
portions of the Oklahoma system are directly located in the Anadarko and Arkoma
Basins. Tejas also has access to the Hugoton, Permian and San Juan Basins
through interconnections with other pipeline systems. The Louisiana systems
consist of 2 to 26 inch diameter gathering and transmission lines and lesser
diameter

lateral lines in North and South Louisiana. For a pictorial presentation of the
pipeline systems described above see the map included on page 5 of this Item 1.

NATURAL GAS TRANSPORTATION

      Tejas' business includes transporting natural gas through its pipelines
for others on a fee basis. Tejas receives natural gas from producers, other
pipelines or shippers through system interconnects and redelivers the natural
gas at other points. Transportation agreements provide Tejas with a fee per unit
of volume transported. During 1996 and 1995, Tejas delivered an average of 2,049
MMcf and 1,469 MMcf per day, respectively, under transportation agreements. The
increase in volumes during 1996 is primarily the result of the Transok
acquisition.

NATURAL GAS STORAGE FACILITIES

      The following table summarizes Tejas' natural gas storage operations for
1996.

(1)   Storage facility is leased to Tejas.

      Tejas purchased the West Clear Lake Storage Facility ("WCLSF") from Exxon
in September 1993. This storage facility, strategically located near the
Houston Ship Channel, is one of the largest natural gas storage reservoirs in
Texas. Exclusive of $22.5 million of cushion gas expenditures, Tejas' cumulative
WCLSF capital expenditures of $18.1 million (primarily for the addition of
electrical compressors) have increased the availability of natural gas and the
operational flexibility of the WCLSF by increasing injection rates from 80 MMcf
per day to 240 MMcf per day and the withdrawal rates from 220 MMcf per day to
550 MMcf per day. This permits Tejas to sell approximately 25 Bcf of additional
natural gas volumes annually out of the storage facility and to provide
additional volumes to accommodate the seasonal needs of customers. Further
development of the WCLSF is possible and Tejas will continue to monitor and
review the economic benefit of such development.

      Tejas owns, as a result of the Transok acquisition, a storage facility in
Oklahoma ("Greasy Creek"). This facility enables Transok to meet demands for
natural gas during periods of peak delivery without incurring peak demand
charges from suppliers of natural gas and provides Transok flexibility in
managing its gas inventory. Tejas is currently in the process of enhancing the
withdrawal and injection capacities of this facility.

                                      8
<PAGE>
      In late 1992, Tejas began operation of a leased salt dome ("Grand Bayou")
natural gas storage facility near Napoleonville, Louisiana. The storage facility
is designed to support the supply swing requirements relating to significant
business with electric utility companies and natural gas distribution companies
resulting from contracts entered into with such companies as well as other new
business that may develop in the future. The facility site was obtained under a
10-year lease, under which Tejas has an option to extend the lease term for an
additional 10 years. An affiliate of the lessor has contractual rights to 10% of
the facility's storage and withdrawal capacity. Another company purchased a 25%
interest in the storage project and contributed a proportionate amount of the
construction costs, in order to obtain greater delivery flexibility for its peak
winter requirements. Its rights to total withdrawal capacity is reduced to
approximately 5% during Tejas' peak summer demand period.

      The operation of Tejas' natural gas storage facilities is an integral part
of Tejas' business. Tejas typically hedges all or a portion of its natural gas
volumes held in storage utilizing the futures, swaps and options markets.
Natural gas volumes held in storage enable Tejas to respond quickly to changing
market conditions and to take advantage of seasonal price variations and peak
demand periods. This storage capacity creates an opportunity for Tejas to
purchase natural gas at times of lower demand when prices are typically lower
and to make sales during periods of peak demand when prices are typically
higher. To accomplish this strategy, Tejas may purchase gas for injection into
storage, either currently or in future periods, and simultaneously sell
equivalent volumes of gas for delivery in other periods.

NATURAL GAS SALES AND MARKETING

      Through Coral, Tejas sells natural gas to electric utilities, local
distribution companies, industrial end-users, marketing affiliates of other
pipeline companies and gas marketing companies. Tejas' electric utility and
industrial customers normally consume the natural gas in their own operations
while local distribution companies, pipeline affiliated customers, and gas
marketing customers generally resell the natural gas. Tejas' natural gas sales
are made pursuant to both long-term contracts which range in term from one to 20
1/2 years and short-term agreements which generally range from one month to one
year in duration. An interest in Tejas' long-term sales contracts has been
contributed to Coral. For further discussion of Coral see "GENERAL" in this Item
1. and Note 8 of "Notes to Consolidated Financial Statements."

      Coral conducts natural gas marketing activities for Tejas and Shell. In
addition, Coral has received regulatory approval to market electricity in
wholesale markets and commenced such activities in the third quarter of 1996.
Coral initially began marketing 3.7 Bcf per day of Tejas and Shell natural gas
volumes. As of December 31, 1996, sales of natural gas were in excess of 6.1 Bcf
per day. Tejas provides Coral access to Tejas' natural gas pipelines which have
interconnects with other pipelines serving the U.S. and access to gas supplies
from Tejas' storage facilities and gathering and transmission systems located in
Texas, Oklahoma and Louisiana. Shell dedicates approximately 2 Bcf per day of
gross natural gas production and approximately 5.5 trillion cubic feet of
natural gas reserves. Tejas has committed to Coral substantially all of its
natural gas supply, and Shell has committed to Coral substantially all of its
gas production in the United States (excluding Alaska and Hawaii). Coral was
initially staffed with employees from Tejas and Shell. In addition, Tejas
provides intrastate marketing expertise, and Shell provides interstate marketing
expertise, as well as treasury and administrative support services. Coral has
also entered into a contractual arrangement with Bankers Trust to assist in
providing a variety of specially tailored risk management services.

      Tejas and Shell have each contributed cash and economic interests in
natural gas sales contracts to Coral for their respective interests. Each
partner has received equity credit for long-term natural gas contract
commitments to the partnership. If actual volumes and margins from these
contracts fail to meet

                                        9
<PAGE>
targeted contract levels, the responsible partner is subject to make-up
payments. If Coral is unable to take all of the natural gas tendered for
delivery by the parties, Coral is obligated to pay for such natural gas at the
price that would have otherwise been applicable, mitigated by the amount
obtained from any sales of such natural gas to third parties.

LONG-TERM SALES AGREEMENTS

      The majority of Tejas' long-term sales agreements provide for minimum
annual volumes to be delivered at market prices, determined monthly, plus a
predetermined margin. A small portion of Tejas' long-term sales are also made
under contracts whereby natural gas produced from a designated geographical
area, and which Tejas elects to purchase, is sold at a fixed price.
Substantially all of Tejas' long-term sales are made to electric utility
companies, local natural gas distribution companies and industrial customers.
The margins available to Tejas from such sales are greater than those currently
available under short-term contracts because of the additional services provided
by Tejas in connection with such sales. These services include aggregation of
supplies, assurance of supplies and the dedication of such Tejas facilities as
are necessary to provide for large swings in the volumes delivered to the
customers as the customers' requirements vary from season to season or from day
to day. Long-term sales contracts comprised approximately 43% and 42% of total
system sales volumes in 1996 and 1995, respectively. As these long-term
contracts expire, the percentage of volumes sold by Tejas under such contracts
will decrease unless Tejas can negotiate renewals or extensions thereof or
obtain new long-term contracts to replace the volumes sold thereunder. There can
be no assurance that Tejas will be able to replace the revenues lost under such
long-term contracts with equally profitable transportation or sales
opportunities.

SHORT-TERM SALES CONTRACTS

      Short-term sales agreements generally provide for delivery of negotiated
volumes for a 30-day period at prevailing market prices. Customers for
short-term sales agreements are principally industrial companies, marketing
affiliates of other pipeline companies, and gas marketing companies, but may
also include local distribution companies and electric utilities. Profit margins
for such sales are currently much lower than those made under long-term sales
contracts and vary from month to month since they are affected by competition
for natural gas markets at the time of sale as well as the cost of natural gas
supplies. The cost of supplies will vary depending upon competition for such
supplies and the services provided by Tejas to producers, including gathering of
the natural gas from the producers' wells, compression and dehydration. Tejas
delivered from its systems approximately 57% and 58% under short-term sales
agreements during 1996 and 1995, respectively.

SEASONAL VARIATIONS

      Tejas' natural gas sales are affected by seasonal changes in demand for
natural gas because of weather. Tejas has its greatest demands during the winter
heating season and the summer air conditioning season as greater volumes,
revenues and earnings from operations are usually experienced during those
periods of the year. Variations in extremes of weather from year to year have in
the past resulted in significant variations in Tejas' natural gas throughput,
revenues and earnings for those years.

PRINCIPAL CUSTOMERS

      Sales to Coral represented 38% and 10% of Tejas' revenues in 1996 and
1995, respectively. No single customer accounted for 10% or more of Tejas'
revenues in 1994.

                                      10
<PAGE>
NATURAL GAS SUPPLIES

      Tejas purchases natural gas from a variety of suppliers, ranging from
small independent producers to major oil and gas companies and marketing
affiliates of other pipeline companies, under approximately 4,124 long-term and
short-term natural gas purchase contracts. Tejas does not own any natural gas
reserves.

      Natural gas supplies connected to Tejas' pipeline systems in Texas are
concentrated in South Texas, offshore Texas, the onshore Gulf Coast Region of
Texas, the Fort Worth Basin, and in various producing areas in Central and East
Texas. Supplies are also obtained from other producing areas through
interconnections with third-party pipelines.

      South Texas is an area in which active drilling and completion of natural
gas wells have continued over the past several years and in which production
levels have, therefore, remained generally constant. Tejas believes active
drilling in this area will continue because of its geological nature and
relatively high rate of successful well completions.

      Tejas has access to major producing areas and reserves located in the
South Texas, offshore Texas, onshore Gulf Coast and East Texas areas. Tejas'
pipeline systems are connected to the King Ranch production via the King Ranch
Gas Processing Plant tailgate, with further access to additional third-party
production from the McAllen Ranch area. Tejas also expects to benefit from
access to reserves and production of natural gas from the Wilcox Trend in Webb,
Zapata, Starr and Hidalgo Counties.

      The Fort Worth Basin supply is more limited than that of South Texas and
the connected producing wells are subject to greater production rate declines.
While supplies have been relatively stable over the past several years because
of new supplies made available, the maintenance or increase of the supply levels
will be highly dependent upon new drilling in the area.

      The East Texas systems have direct connections to numerous natural gas
wells for a majority of their supplies, but a portion of their supplies are
obtained from other sources in the Carthage area through third-party pipelines.
The ability of these systems to maintain or increase the amount of their
supplies is largely dependent upon Tejas' ability to maintain or increase its
sales volumes to customers at market prices which will allow Tejas to be
competitive in bidding for available supplies.

      The Transok acquisition provides Tejas with a long-lived source of
dedicated natural gas in the Hugoton and Anadarko Basins located in Oklahoma, as
well as access to natural gas produced in the Permian Basin in West Texas and
the Arkoma Basin located in East Oklahoma and Arkansas. These basins are new
supply regions for Tejas. In the last two years, Transok has connected, through
various projects, over 400 MMcf per day in new natural gas well production to
its pipelines. The majority of this new natural gas has come from existing
drilling areas in North Louisiana and West Oklahoma and a new natural gas field
in Stephens County, Oklahoma.

      Additional supplies are purchased principally under short-term contracts
from producers in Southern and offshore Louisiana and offshore Texas through
direct pipeline connections or through interconnections with a number of
third-party pipelines. Tejas also has a direct connection with the Henry Hub, a
major natural gas receipt and delivery point in Southern Louisiana from which
supplies may be obtained from numerous sources. Currently, as well as during the
last several years, natural gas supplies available for purchase on a short-term
basis have been relatively stable and abundant. Tejas foresees no significant
reduction in the availability of such supplies in the near term. However, if
quantities of supplies should diminish in the future, Tejas believes that it can
successfully compete for available supplies because a significant portion of
Tejas' sales will be made under long-term sales contracts which provide for
sales

                                       11
<PAGE>
volumes at market-related prices plus a predetermined margin. This will allow
Tejas to offer suppliers competitive prices as well as a reasonably continuous
market for their supplies.

      During 1996, Tejas purchased approximately 52% of its natural gas supplies
under month-to-month purchase contracts. The remaining 48% of its supplies were
obtained from wells which are directly connected to Tejas' systems and which
Tejas considers to be long-term supplies either because of a lack of competing
pipelines being reasonably accessible to such wells or because of contractual
long-term dedications of the wells' production to Tejas' systems. These supplies
are subject to decline through natural depletion of the wells. The maintenance
or increase in the amount of such long-term supplies will depend upon the
drilling and completion of new natural gas wells and upon Tejas' ability to
successfully compete for such newly developed supplies.

      Purchases of natural gas from Tejas' five largest suppliers accounted for
approximately 32% of its total purchased volume during 1996 and approximately
34% of its total purchased volume during 1995. The largest single supplier
accounted for approximately 12% and 19% of such total volume for 1996 and 1995,
respectively.

      In addition to Tejas' long-term natural gas purchase contract commitments
(at prices approximately equal to prevailing market prices) for volumes covering
approximately 48% of Tejas' 1996 requirements, Tejas has short-term contract
commitments which do not obligate it to purchase fixed quantities of natural gas
and such contracts are effectively terminable by either the buyer or the seller
on relatively short notice (generally 30 to 90 days). However, Tejas is party to
some older, longer-term natural gas purchase contracts under which it is
required, under certain circumstances, to purchase, or to pay for if not taken,
certain minimum volumes of natural gas at set prices (so-called "take-or-pay"
contracts). Possible take-or-pay claims may continue to accrue under such older
contracts until their expiration or renegotiation. Most of these take-or-pay
contracts will expire within the next three years. Payments, if any, made under
these take-or-pay provisions for natural gas not actually taken are sometimes
subject to being recouped out of takes of natural gas in future periods in
accordance with the terms of the contracts. In certain instances, Tejas has
similar take-or-pay provisions in sales contracts with its customers.

      Tejas Gas is a defendant in one pending take-or-pay lawsuit for which
alleged damages in excess of $36 million are claimed against Tejas Gas. See
"ITEM 3. LEGAL PROCEEDINGS" herein. Certain other producers have made claims
against Tejas Gas pursuant to take-or-pay provisions. Tejas estimates that such
claims are not material. Management believes that Tejas has adequate defenses or
recourse to third parties relating to such lawsuit and claims, and does not
believe that these matters will have a material adverse effect on Tejas'
financial condition. However, the ultimate outcome of the lawsuit and such
claims is uncertain at the present time.

      period subsequent to the Transok acquisition while capacity is based upon
      the whole year of operations.
(4)   Operated under guaranteed return contracts.

      Tejas' natural gas processing operations consist of extracting natural gas
liquids (ethane, propane, butanes and heavier products, collectively, "NGLs")
from natural gas supplied by producers and other pipeline companies, either
through Tejas-owned pipelines or directly from other companies' pipelines. After
processing, the residue natural gas is returned to the pipelines. The NGLs
extracted are transported to third-party fractionation facilities where the
products are separated and then generally sold to wholesalers.

      The processing contracts for some of Tejas' natural gas processing plant
operations provide that Tejas receive certain minimum revenues for processing.
The processing contracts for Tejas' other plants generally provide that Tejas
receive all or a portion of the NGLs extracted as its fee for processing, and
the profitability of such plants depends directly upon the volumes and sales
prices of NGLs extracted, the volumes and prices of natural gas consumed in the
processing and the volume of natural gas supplies available for processing.

NATURAL GAS TREATING

      Natural gas treating operations involve removing hydrogen sulfide and
carbon dioxide from natural gas to make it marketable. These services are
normally conducted under long-term contracts for a fee per unit of natural gas
volume treated. Tejas owns and operates two natural gas treating plants in Texas
which have an aggregate treating capacity of approximately 100 MMcf of natural
gas per day. During 1996 and 1995, these plants treated an average of 44 MMcf
and 43 MMcf per day, respectively.

                                       13
<PAGE>
COMPETITION

      Significant competition exists for Tejas in purchasing, marketing,
transporting, gathering, processing and treating of natural gas in many of its
geographic areas of operations. The ability to offer competitive prices,
reasonable assurances of a continuous market and a favorable performance history
with producers are the principal factors in being competitive for supplies.
Additionally, the extent of direct connections between the producers' wells or
gathering facilities and Tejas' gathering or transmission lines and the
connection of Tejas' lines to substantial direct consumers are important
competitive factors. Successful competition for markets depends primarily upon
the ability to deliver natural gas supplies to customers at competitive prices
and in such quantities as the customer may need from time to time as well as
having a record of reliability in performing the required services.

      Currently, a significant portion of Tejas' volumes of natural gas
purchased and resold are under short-term contracts which are subject to
renegotiation of prices and volumes, usually on a monthly basis. Although this
affords Tejas greater flexibility in responding to changing market conditions,
supplies and markets under such contracts are not assured. In addition, excess
supplies in relation to demand causes competition for available markets. Tejas
has numerous competitors in its geographic area of operations, many of which are
larger interstate pipeline companies with more extensive pipeline networks and
greater capital resources. Accordingly, for Tejas to remain competitive it must
continually meet or exceed such competitors' ability to offer reliable services
and competitive pricing. Tejas also faces varying degrees of competition from
the use of alternative energy sources, such as electricity, coal and oil.


EMPLOYEES

      As of December 31, 1996, Tejas had 818 employees which includes 418
employees added as a result of the Transok acquisition. None of Tejas' employees
are represented by a union. Management believes that Tejas' relations with its
employees are satisfactory.

REGULATORY MATTERS

      Tejas' facilities and operations are subject to regulation by various
governmental agencies at both the federal and state level. Tejas' intrastate
operations in Texas are subject to state regulations issued by the Railroad
Commission of Texas under the Cox Act, the Gas Utilities Regulatory Act and the
Natural Resources Code. The Railroad Commission of Texas regulates intrastate
pipeline companies as to rates, services and safety. Tejas' Louisiana operations
are subject to state regulations issued by the Louisiana Public Service
Commission and the Louisiana Department of Natural Resources. The Louisiana
Public Service Commission regulates Tejas' city gate sales. Within the Louisiana
Department of Natural Resources, the Office of Conservation has the authority to
regulate all pipeline interconnections, transportation and construction or
abandonment of facilities, and the Office of Pipeline Safety monitors the
implementation of U.S. Department of Transportation and Louisiana pipeline
safety regulations. Tejas' Oklahoma operations are subject to rules and
regulations issued by the Oklahoma Corporation Commission. The Conservation
Division within the Oklahoma Corporation Commission has the authority to
regulate the conservation of natural gas, the prevention of pollution in
connection with the transportation, processing and storage of natural gas, and
to prohibit discrimination with respect to commercial terms in connection with
the purchase, transportation and gathering of natural gas. The Oklahoma
Corporation Commission also regulates pipeline safety and the construction and
abandonment of pipeline interconnections and other facilities.

                                       14
<PAGE>
      At the federal level, Tejas is subject to regulations of the Federal
Energy Regulatory Commission (the "FERC") under the Natural Gas Policy Act of
1978 and regulations implementing the Federal Natural Gas Pipeline Safety Act of
1968, which concerns pipeline safety. With respect to interstate pipeline
operations, the FERC has promulgated a series of orders that have led to the
restructuring of pipeline services and to the requirements that all interstate
pipelines provide "open access" service to anyone so requesting. While the
detailed "open access" regulations do not apply to intrastate pipelines such as
those of Tejas, the FERC does require that intrastate pipelines which provide
certain interstate services pursuant to Section 311 of the Natural Gas Policy
Act do so on an open and nondiscriminatory basis and make certain filings and
reports in compliance with the regulations. These "open access" regulations are
designed to encourage the transportation of gas on a nondiscriminatory basis to
increase the competitiveness and flexibility of natural gas markets. Several of
Tejas' pipelines are providing Section 311 service and compliance with the FERC
regulations has posed no significant problem. The rates for the pipelines
providing Section 311 service in Texas are reviewed and approved by the Texas
Railroad Commission. The rates for two of the pipelines providing Section 311
service in Louisiana are reviewed and approved by the Louisiana Public Service
Commission, and the maximum rates for a third pipeline and the storage facility
in Louisiana are submitted to the FERC for review and approval. For the two
pipelines and a storage facility in Oklahoma which provide Section 311 service,
maximum rates are submitted to the FERC for review and approval. Tejas has
pipelines which qualify to provide the means to purchase natural gas supplies
from interstate sources for redelivery and sale to intrastate markets without
regulation by the FERC. In addition to the above regulations, the natural gas
industry has historically been subject to numerous other forms of federal and
state regulation, and the effect of future regulations upon Tejas cannot be
predicted.

      The operations of Tejas are subject to various federal, state and local
environmental laws which can increase the costs of planning, designing,
installing and operating its facilities. In most instances, the regulatory
requirements relate to water and air pollution control measures. Operations in
Texas are subject to the Texas Clean Air Act as administered by the Texas
Natural Resources Conservation Commission, which Act restricts emissions from
wells, pipelines, compressors, processing plants and treating plants.
Furthermore, the Railroad Commission of Texas has the authority to issue permits
and regulations necessary to prevent environmental pollution by pipeline
operations. The Louisiana operations are subject to regulation by the Louisiana
Conservation Commission and other state agencies. The Oklahoma operations are
subject to regulation by the Department of Environmental Quality and other state
agencies. The operations of Tejas are also subject to regulation on the federal
level by the Federal Environmental Protection Agency. Tejas is also subject to
other federal, state and local laws covering the handling or discharging into
the environment of materials used by Tejas, or otherwise relating to protection
of the environment, safety and health. The exact nature of environmental issues
which Tejas and its subsidiaries may encounter in the future cannot be
predicted. Additional environmental liabilities may result in the future as more
stringent environmental laws and regulations are implemented. The nature of
Tejas' business requires Tejas to monitor its compliance with environmental laws
and regulations and assess the likelihood of Tejas incurring environmental
liabilities, including liabilities associated with remediation. At present, no
estimate of any such liability, or range of liability amounts, can be made.
There can be no assurance that the amount of any such liabilities would not be
material.

      Transok leases all of the pipeline facilities of Palo Duro Pipeline
Company (Palo Duro) in Texas. The Palo Duro pipeline system provides
transportation service both in intrastate commerce and under Section 311 of the
Natural Gas Policy Act. On April 29, 1994, Transok filed an Application for
Review of Reasonableness of Transportation Rate for the Palo Duro system with
the Texas Railroad Commission proposing a maximum rate of $0.20 per million
British thermal units ("MMBtu") (plus taxes) plus the shipper's pro rata share
of compressor fuel and lost and unaccounted for volumes. The matter is still
pending before the Texas Railroad Commission and the ultimate outcome of this
filing is unknown at this time.

      On November 1, 1995, Transok filed a rate case with the FERC in Docket No.
PR96-2 for approval of maximum cost of service rates for Section 311
transportation on the Transok pipeline system exclusive of acquisitions after
1990 (the "Traditional System"). Transok requested approval of maximum rates of
$2.736 per MMBtu and $0.1751 per MMBtu for firm reservation and firm usage
charges, respectively, $0.265 per MMBtu for interruptible plus the shipper's pro
rata share of compressor fuel and 0.5% of the volumes transported as an
allowance for lost and unaccounted for natural gas. Transok also informed the
FERC in the case that it was ceasing to offer new firm transportation service
and was seeking approval of the above firm rates only for the purpose of
collecting the rates contained in firm transportation contracts still in effect
as of November 1, 1995. Transok is pursuing a settlement of the matter with the
FERC staff and the intervenors in the proceedings.

      Transok's Greasy Creek Storage Facility, located on the Traditional
System, is currently approved by the FERC to charge market based rates for up to
4.0 Bcf of the facility's capacity. The rates are effective for an indefinite
time period, subject to Transok informing the FERC if it becomes affiliated with
a local distribution company outside of the State of Oklahoma. The FERC is
reviewing a Section 311 rate filing for market based rates for the Grand Bayou
Storage Facility located in Louisiana.

      On May 1, 1996, Transok filed a rate case with the FERC in Docket No.
PR96-7 for approval of cost of service rates for Section 311 transportation on
the Anadarko System. Transok requested approval of maximum rates of $0.2541 per
MMBtu for interruptible plus the shipper's pro rata share of compressor fuel and
0.5% of the volumes transported as an allowance for lost and unaccounted for
natural gas. Transok is pursuing a settlement of the matter with the FERC staff
and the intervenors in the proceedings.

ITEM 2. PROPERTIES

      A description of Tejas' properties is included under "ITEM 1. BUSINESS"
above and is incorporated herein by reference. Substantially all of Tejas' net
assets reside at the subsidiary level. The obligations under the Amended Transok
Credit Facility and the assumed $200 million of Medium Term Notes ("MTN's") are
secured by certain intercompany notes, by the capital stock of all of Transok's
subsidiaries and certain partnership interests held by Transok, and are
guaranteed by such subsidiaries. The obligations under the TAHC and TNGC
revolving credit agreements are secured by the capital stock, partnership
interests and various intercompany notes of all material subsidiaries and
partnerships of TAHC (excluding the capital stock of Acadian, but including the
capital stock and partnership interests of the material operating subsidiaries
and partnerships of Acadian) and are guaranteed by such subsidiaries and
partnerships. The notes payable related to Lewis and Pleasants Counties' bonds
are secured by bank letters of credit which in turn are secured by mortgages on
two natural gas processing plants located in West Virginia.

ITEM 3. LEGAL PROCEEDINGS

THE LONG TRUST LITIGATION

      Tejas is a defendant or party in various lawsuits that have risen in the
ordinary course of Tejas' business. In particular, a subsidiary of Tejas is a
defendant in THE LONG TRUSTS V. TEJAS GAS CORP. ET. AL., 123rd Judicial District
Court, Panola County, Texas, filed March 1, 1989, in which plaintiffs assert
claims and allege damages for breach of contract and failure to take-or-pay for
natural gas pursuant to three natural gas purchase contracts. Plaintiffs allege
that, in addition to failing to take-or-pay for gas, Tejas breached (a) one of
the contracts by failing to take a minimum quantity of gas and to install and
maintain pipeline facilities sufficient to permit Tejas to meet its quantity
purchase obligations, and (b) all three contracts by

                                       16
<PAGE>
failing to take gas in quantities sufficient to enable plaintiffs to produce
ratably with other producers in a common reservoir. In plaintiffs' Sixth Amended
Original Petition filed June 6, 1995, the plaintiffs are seeking take-or-pay
damages for the ten year period 1984-1994 in excess of $36 million, plus
pre-judgment interest, post-judgment interest, attorneys' fees and court costs
and other unspecified actual damages. In connection with their depositions in
this matter, certain expert witnesses retained by The Long Trusts have presented
damage models purporting to show approximately $60 million in take-or-pay
damages and $70 million for failure to take The Long Trusts' gas ratably.
Management disputes The Long Trusts' claims and believes that The Long Trusts'
damage models are seriously flawed. On January 6, 1993, the court entered an
interlocutory summary judgment order granting in part and denying in part
plaintiffs' motions for summary judgment. The court found, among other things,
as a matter of law that (a) Tejas breached the minimum take obligations under
one of the contracts, (b) Tejas is not entitled to any credits or offsets for
natural gas purchased by third parties, and (c) the "availability" of natural
gas for take-or-pay purposes is established by the delivery capacity testing
procedures in the contracts. Damages, if any, have not been determined. The
effect of this order on Tejas' case is unclear and Tejas has sought
clarification and rehearing, but intends nevertheless to defend its position
aggressively.

      Because of the relationship between The Long Trusts contracts and certain
contracts between Tejas and Valero Transmission Company ("VTC"), and in order to
resolve existing and potential claims and disputes, Tejas, VTC and Valero
Transmission, L.P. ("VTLP") entered into an agreement, pursuant to which, among
other things, Tejas, VTC and VTLP would cooperate in the conduct of The Long
Trusts litigation, and VTC and VTLP would bear a substantial portion of the
costs of any appeal and of the amount of any nonappealable final judgment
rendered against Tejas. On April 15, 1994, the plaintiffs named VTC and VTLP
(collectively "Valero") as additional defendants to the lawsuit, alleging that
Valero intentionally and maliciously interfered with the plaintiffs' contracts
with Tejas. In its Sixth Amended Original Petition, plaintiffs are seeking
damages against Valero in an amount in excess of $36 million, and plaintiffs
added a conspiracy claim against Tejas alleging that Tejas conspired with Valero
in interfering with the contracts. Plaintiffs also have added a claim for
exemplary damages treble the amount of the actual damages, if any, found by the
court for the interference and conspiracy claims. Plaintiffs assert that Tejas
should be jointly liable with Valero for the damages plaintiffs have asserted
against Valero. Although Tejas has not obtained a formal opinion, based on
discussions with outside counsel and an internal examination of this lawsuit,
management believes that it has adequate defenses or recourse to third parties
relating to such lawsuit and does not believe this matter will have a material
adverse effect on Tejas' financial condition.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      There were no matters submitted to a vote of security holders during the
fourth quarter of 1996.

      On March 17, 1997, the last reported sales price for the Common Stock, as
reported on the NYSE Composite Tape, was $44 7/8 per share. On March 17, 1997,
there were 914 stockholders of record of the Common Stock.

      On July 19, 1995, Tejas' Board of Directors authorized a stock dividend of
one-tenth of one share of Common Stock for each share of Common Stock
outstanding payable to stockholders of record on July 27, 1995. On April 11,
1996, Tejas' Board of Directors authorized a three-for-two stock split effected
in the form of a stock dividend, effective May 13, 1996 for stockholders of
record as of April 26, 1996. Stock prices used in this Item 5. have been
adjusted to give retroactive effect to the 1995 stock dividend and the 1996
three-for-two stock split for periods prior to April, 1996. Such adjusted prices
may not reflect prices which may actually have occurred had such transactions
been in effect during the periods presented.

      On July 22, 1996, Tejas sold 3,075,000 shares of its Common Stock in an
underwritten public offering. Net proceeds to Tejas from the sale of the Common
Stock, approximately $103 million, were used to reduce indebtedness under the
Transok Credit Facility (see Note 12 of "Notes to Consolidated Financial
Statements").

      No cash dividends have been paid on the Common Stock by Tejas since its
shares were publicly distributed, and Tejas does not currently intend to pay
cash dividends on its Common Stock. Such policy will be reviewed by the Board of
Directors of Tejas from time to time in light of, among other things, Tejas'
earnings and financial position, capital requirements and limitations imposed by
its credit facilities. The terms of Tejas' outstanding 9.96% Cumulative
Preferred Stock (the "9.96% Preferred Stock") and 5 1/4% Convertible Preferred
Stock (the "5 1/4% Preferred Stock") restrict the distributions Tejas may make
if there is any arrearage in the dividends thereon. Tejas' credit facilities
restrict the distributions it may receive from its subsidiaries, as more fully
described in Note 5 of "Notes to Consolidated Financial Statements" and "ITEM 7.
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

      The following is a discussion of Tejas' financial condition, results of
operations, capital resources and liquidity. This discussion and analysis should
be read in conjunction with the Consolidated Financial Statements of Tejas and
the notes thereto included in "Item 8. Financial Statements and Supplementary
Data" of this report.

      On June 6, 1996, Tejas acquired pipeline assets and related facilities and
leased seven natural gas processing plants as a result of the acquisition of
Transok, Inc., as more fully discussed herein under "Capital Resources,
Liquidity, and Outlook." The results of operations for the assets acquired or
leased (hereafter referred to as the "Transok Operations") are included herein
for the period subsequent to June 6, 1996. Earnings per common share have been
adjusted to give retroactive effect to a stock dividend of one-tenth of one
share of Common Stock on each share of Common Stock outstanding paid to
stockholders of record in July 1995 and a three-for-two stock split implemented
in April 1996, as if the stock dividend and stock split had occurred at the
beginning of each period presented.

RESULTS OF OPERATIONS

                    YEAR ENDED DECEMBER 31, 1996 VERSUS 1995

      Tejas' net earnings increased to $43.5 million during 1996 from $32.9
million during 1995. Net earnings applicable to common stockholders increased
$10.6 million to $35.1 million during 1996 compared to $24.5 million in 1995.
Net earnings per common share were $1.87 during 1996, an increase of 33% from
$1.41 during 1995. As more fully discussed below, Tejas' growth in net earnings
for the year ended December 31, 1996 was the result of several factors, the most
significant of which was the inclusion of the Transok Operations. Net earnings
applicable to common stock and earnings per share results include a provision
for dividends on Tejas' 9.96% Preferred Stock and Tejas' 5 1/4% Preferred Stock.

REVENUES

      Revenues increased by $1.1 billion to $2.1 billion during 1996. This
increase in revenues resulted primarily from increases in natural gas sales
prices and increases in systems sales throughput due to weather-related demands
and the inclusion of the Transok Operations. Revenues attributable to the
Transok Operations for the period subsequent to June 6, 1996, accounted for
approximately 38% of the total increase.

NATURAL GAS SYSTEMS

      Sales, storage, gathering and transportation of natural gas through its
owned and/or operated natural gas pipeline systems and storage facilities is
Tejas' core business. Volumes related to these systems increased 32% to 4.1 Bcf
per day during 1996 from 3.1 Bcf per day in 1995, of which approximately .8 Bcf
per day was attributable to the Transok Operations and approximately .2 Bcf was
attributable to increased sales from Tejas' pre-existing operations. The
increase in systems volumes contributed to a corresponding increase in gross
profit (revenue less cost of sales) of $50 million to $206.3 million during 1996
when compared to gross profit of $156.3 million generated in 1995. The majority
of the $50 million increase in gross profit was a result of the Transok
Operations.

                                       20
<PAGE>

NATURAL GAS PROCESSING/TREATING/OFF-SYSTEM MARKETING

      Gross profit from Tejas' natural gas processing, treating and off-system
marketing was $44.8 million during 1996, compared to $10.3 million in 1995. The
$34.5 million increase in gross profit from these activities occurred mainly due
to the inclusion of the Transok Operations.

ENERGY MARKETING PARTNERSHIP - CORAL ENERGY, L.P.

      In November 1995, Coral, an energy marketing joint venture between Tejas
and Shell, began operations. During 1996, Coral's total sales volumes of 4.6 Bcf
of natural gas per day contributed approximately $8.4 million to Tejas' pre-tax
earnings, which is included in Equity Earnings of Unconsolidated Entities,
compared to 1995's two month sales volumes of .6 Bcf of natural gas per day and
pre-tax earnings of $.7 million, respectively.

OPERATING EXPENSES/DEPRECIATION/GENERAL AND ADMINISTRATIVE EXPENSES

      Operating expenses, depreciation, and general and administrative expenses
increased by $53.1 million during 1996. Of this $53.1 million increase, $48.4
million related to the Transok Operations. The remainder of the increase was
attributable to increases in ad valorem taxes, repair and maintenance expense
mainly related to the WCLSF and the employee incentive plan which rewards
certain of Tejas' employees with bonuses when the company achieves certain
annual financial growth targets.

OTHER INCOME (EXPENSE)

      Interest Expense increased by $18 million during 1996. The increase
relates to borrowings used to finance the Transok acquisition. Expenses related
to minority interests increased $4.5 million as a result of $3.7 million in
distributions on preferred membership units of a subsidiary issued in December
1995 and $.8 million of minority interest expense recognized for Transok's
majority owned subsidiaries.

INCOME TAXES

      Income tax expense increased by $6.6 million in 1996 over 1995 due
primarily to increased pre-tax earnings and state income tax related to the
Transok Operations.

                    YEAR ENDED DECEMBER 31, 1995 VERSUS 1994

      Tejas' net earnings increased to $32.9 million for the year ended December
31, 1995, compared to $30.5 million for the year ended December 31, 1994, an 8%
increase. Net earnings applicable to common stock for the year ended December
31, 1995, were $24.5 million, up from $22.2 million in 1994. Earnings per common
share increased to $1.41 for the 1995 annual period as compared to $1.25 for the
1994 annual period, an increase of 13%. Net earnings applicable to common stock
and per share results for 1995 and 1994 are after provisions for $8.4 million in
dividends on Tejas' 9.96% Preferred Stock issued in February 1993 and Tejas' 5
1/4% Preferred Stock issued in November 1993.

NATURAL GAS SYSTEMS

      Sales, storage and transportation of natural gas through its owned and/or
operated natural gas pipeline systems and gas storage facilities is Tejas' core
business. Volumes related to those activities accounted for 97% of total systems
throughput and 95%, or $158.3 million, of gross profit during 1995 as compared
to 97% of total throughput and 95%, or $150.1 million, of gross profit in 1994.
Improved sales

                                       21
<PAGE>
volumes, a $4.5 million gain associated with a long-term gas sales contract, and
gas purchase and sales activity supported by Tejas' WCLSF were partially offset
by lower transportation volumes. (For further discussion of WCLSF, see "Storage
Facilities," included in Item 1. herein.) Transportation volumes were impacted
by the expiration of two low margin transportation contracts and a reduction in
volumes nominated under a third low margin contract. In addition, transportation
volumes were negatively impacted by warmer than normal weather in Tejas' market
area during the first half of 1995.

      Revenues for Tejas' natural gas systems increased to $1,012.5 million in
1995 as compared to $999.3 million for 1994, an increase of $13.2 million. This
increase resulted from increased system sales volumes which were partially
offset by lower average sales prices and decreased transport volumes.

NATURAL GAS PROCESSING/OFF-SYSTEM MARKETING

      Natural gas processing and off-system marketing activities contributed
approximately 2.4% and 0.3%, respectively, to total 1995 throughput and 4.8% and
0.1%, respectively, to gross profit. Gross profit from these two components of
Tejas' operations increased to $8.2 million in 1995 as compared to $8 million in
1994 as a result of lower fuel and shrinkage costs for natural gas processing.

      Revenues for natural gas processing and off-system marketing decreased to
$31.1 million in 1995 as compared to $32.6 million in 1994, as a result of
decreased throughput and production by suppliers.

OPERATING EXPENSES/DEPRECIATION/GENERAL AND ADMINISTRATIVE EXPENSES

      Operating expenses, depreciation, and general and administrative expenses
increased by $4 million during 1995 over 1994. Reduced operating expenses and
depreciation as a result of a small, non-strategic system in Louisiana disposed
of during the second quarter of 1995, was partially offset by increased ad
valorem taxes along with the depreciation on the fixed assets of a small
gathering and marketing company acquired in February 1995 and other capital
expenditures.

OTHER INCOME (EXPENSE)

      Equity in earnings (loss) of unconsolidated entities decreased by $1.2
million in 1995 over 1994 reflecting Tejas' share of losses in Evangeline Gas
Pipeline Company, L.P. ("Evangeline") and decreased earnings of Gulf Coast
Natural Gas Company ("GCN"). The decreased earnings from GCN and Tejas'
increased share of the losses incurred by Evangeline was partially offset by the
two months of earnings of Coral. Earnings in GCN were lower primarily due to
lower margins on sales of natural gas volumes. In 1995, Tejas' interests in
Evangeline bore 100% of all losses compared to 45% in 1994.

      A gain of approximately $1.6 million, net of certain reserves, was
recognized by Tejas during the second quarter of 1995, on the sale of a small,
non-strategic gathering system located offshore Louisiana.

      Interest expense increased by $1.5 million in 1995 as compared to 1994
primarily due to a slightly higher effective rate of interest and an increase in
the average outstanding debt balance.

INCOME TAXES

      Income tax expense increased $1.4 million in 1995 over 1994 due to
increased pre-tax earnings.

CAPITAL RESOURCES, LIQUIDITY AND OUTLOOK

CASH FLOWS FROM OPERATING ACTIVITIES

      For the year ended December 31, 1996, net cash provided by operating
activities totaled $95.1 million as compared to $61.3 million for the same
period in 1995. This $33.8 million increase in net cash provided by operations
is due primarily to a $36.3 million increase in net earnings adjusted for
depreciation and amortization and other non-cash items. Excluding net changes in
the components of working capital, Tejas' operating activities generated $112.7
million in cash during 1996 as compared to $76.4 million during 1995 mainly due
to the addition of the Transok Operations.

CASH FLOWS FROM INVESTING ACTIVITIES

      Net cash used in investing activities totaled $514.4 million. Capital
expenditures for 1996 totaled approximately $620.4 million which included $568.5
million for the Transok acquisition, $32.3 million for an expansion project in
Oklahoma and $7.8 million to increase the operational capacity of the WCLSF.
Cash flows used in acquisitions and capital expenditures were offset by the sale
of three non-strategic assets which generated cash proceeds of approximately
$110 million.

CASH FLOWS FROM FINANCING ACTIVITIES

      Net cash provided by financing activities totaled $434.7 million which was
comprised primarily of proceeds from the July 1996 public offering of common
stock and borrowings related to the Transok acquisition. Net proceeds from the
common stock offering and the sale of three non-strategic Transok assets were
primarily used to reduce the Transok acquisition debt (see "LIQUIDITY" below).

LIQUIDITY

      Tejas' net cash from operating activities increased to $95.1 million at
December 31, 1996, a change of $33.8 million from $61.3 million reported at
December 31, 1995. This improvement was due mainly to increases in net earnings,
depreciation and amortization, and deferred income taxes. Working capital stood
at $28.7 million at year-end 1996, compared to $40.6 million at year-end 1995.
This $11.9 million decrease in working capital is principally due to increased
accrued liabilities associated with the Transok acquisition.

      At December 31, 1996, Tejas' long-term debt with banks totaled $639.6
million, consisting of $443.8 million borrowed under its $480 million revolving
credit facilities established for its subsidiaries TAHC and TNGC, and
approximately $196 million borrowed under the $275 million Amended Transok
Credit Facility. In addition, Tejas has $200 million of long-term debt that was
retained by Transok as part of the Transok acquisition, and $8.2 million in
notes payable, net of $2 million in current maturities, related to Industrial
Development Refunding Revenue Bonds issued by Lewis and Pleasants Counties, West
Virginia.

      To finance the cash requirements for the Transok acquisition, Tejas
borrowed (i) $178 million under its existing credit facilities and (ii) $387
million, net of a $38 million voluntary prepayment, under the $425 million
Transok Credit Facility. The outstanding balance under the Transok Credit
Facility was reduced to approximately $196 million by year-end 1996 primarily
due to the application of proceeds received by Tejas subsequent to the Transok
acquisition from the sale of common stock (see Note 12 of "Notes to Consolidated
Financial Statements") and the sale of certain non-strategic assets (see Note 3
of "Notes to Consolidated Financial Statements"). Prior to year-end, the Transok
Credit Facility was amended. The principal changes to the credit facility
included extending the maturity date from

                                       23
<PAGE>
December 31, 1997 to December 31, 2004, lowering the interest rate margins over
LIBOR, subject to a minimum margin for a limited period of time, and setting the
commitment amount at $275 million. The Amended Transok Credit Facility bears
interest, at Tejas' option, based upon either prime rate or LIBOR. Depending
upon Transok's funded debt to capitalization ratio, the margins over LIBOR that
Transok must pay vary from a minimum of 0.5% to a maximum of 1.25%. Based upon
the December 31, 1996 outstanding balance of approximately $196 million, the
Amended Transok Credit Facility had available borrowings of approximately $79
million and bore interest at Tejas' option, of prime or LIBOR plus 1.0%. Under
the terms of the Amended Transok Credit Facility, after two years the revolver
will, unless extended at the option of the lenders, convert into a six year
reducing revolver. Unless extended, commitment reductions of approximately $8.6
million per quarter will begin March 31, 1999 with the final remaining
commitment reduction to occur on December 31, 2004. Nevertheless, based upon the
current terms of the Amended Transok Credit Facility and the outstanding
principal balance thereunder at December 31, 1996, no principal payments are
required until the year 2001.

      Effective January 12, 1995, Tejas amended its credit facilities to roll-up
a majority of the existing bank debt of its three principal operating
subsidiaries into a single, $455 million, eight-year, revolving credit facility
at a newly formed subsidiary, TAHC. One of the subsidiaries, TNGC, retained a
$25 million working capital facility with terms and conditions substantially
similar to the rolled-up facility. The two facilities combined provide TAHC and
its subsidiaries with $480 million in borrowing capacity. Both the TAHC and TNGC
credit facilities (the "Credit Agreements") bear interest at Tejas' option,
based on either prime rate or LIBOR. The margins over LIBOR that TAHC and TNGC
must pay vary, depending on TAHC's funded debt to capitalization ratio, from a
minimum of 0.5% to a maximum of 1.25%. Based upon borrowings at December 31,
1996, of $443.8 million, and after considering restrictions to provide for a $10
million letter of credit and borrowings under its money market credit lines
(offset by cash available pursuant to the terms of such money market credit
lines), approximately $26.2 million of additional borrowings were available
under these amended facilities. Additionally, at year-end, based upon TAHC's
funded debt to capitalization ratio test, both the TAHC and TNGC credit
facilities bore interest at Tejas' option, of prime or LIBOR plus 0.75%. Under
the terms of the Credit Agreements, after two years the revolving credit
facilities will convert into six-year reducing revolving credit agreements
unless extended at the option of the lenders. During the fourth quarter of 1996
the lenders under the Credit Agreements agreed to extend by one year both the
maturity date and the period in which commitment reductions commence. As such,
commitment reductions aggregating $15 million per quarter are scheduled to begin
March 31, 1999 with the final remaining commitment reduction to occur on
December 31, 2004. Based upon the current terms of the Credit Agreements and the
outstanding principal balances thereunder at December 31, 1996, no principal
payments are required until the year 1999.

      The obligations under the Amended Transok Credit Facility are secured by
certain intercompany notes, the capital stock of all of Transok's subsidiaries
and certain partnership interests held by Transok, and are guaranteed by such
subsidiaries. The obligations under the Credit Agreements are secured by the
capital stock, partnership interests and various intercompany notes of all
material subsidiaries and partnerships of TAHC (excluding the capital stock of
Acadian, but including the capital stock and partnership interests of the
material operating subsidiaries and partnerships of Acadian) and are guaranteed
by such subsidiaries and partnerships. The notes payable related to the Lewis
and Pleasants Counties' bonds are secured by bank letters of credit which in
turn are secured by mortgages on two natural gas processing plants located in
West Virginia. The notes are also subject to certain covenants and require that
Tejas' subsidiaries, TAHC and Gulf Energy Gathering & Processing Corporation,
maintain certain financial standards. All of Tejas' credit facilities are
subject to certain covenants, including the maintenance of certain financial
ratios, with which Tejas expects to be able to comply in the ordinary course of
business.

      Although TAHC, TNGC and Transok have additional borrowing capacity
available under the Credit Agreements and the Amended Transok Credit Facility,
the amount of loans, advances and dividends that 

                                       24
<PAGE>
may be made to Tejas from TAHC, TNGC and Transok under the Credit Agreements and
the Amended Transok Credit Facility is subject to certain limitations. At
year-end 1996, the permitted amount of such payments was $204.1 million. Such
limitations as herein described are not expected to have any material effect on
the ability of Tejas to meet its cash obligations. Tejas' liquidity is
ultimately dependent on cash generated by operations, and Tejas believes its
earnings from operations will generate sufficient cash to fund expansion
projects, make required debt payments and meet anticipated dividend requirements
of the 9.96% Preferred Stock and 5 1/4% Preferred Stock in the foreseeable
future.

      Tejas has uncommitted money market credit lines which allow Tejas to
borrow up to $50 million for periods of up to two months. Any such borrowings
are unsecured and may be extended for additional periods if agreed to by the
lenders. At December 31, 1996, Tejas had no borrowings outstanding under such
lines. Tejas has agreed to maintain funds including, but not limited to,
availability under the Credit Agreements and the Amended Transok Credit Facility
sufficient to repay borrowings under the money market credit lines.

      On December 29, 1995, a subsidiary of Tejas, Tejas-Magnolia Energy, L.L.C.
("Tejas-Magnolia"), issued preferred equity interests to a third party in return
for a capital investment of $55 million. Tejas- Magnolia is required to make
preferred distributions to the third party which constitute a return on capital
(at an effective fixed after tax cost to Tejas of 4.2%) and return of capital
over an eight-year term. Annual distributions (including returns on and of
capital) of approximately $8.7 million are payable from 1996 through 2001 and
approximately $9.5 million in each of 2002 and 2003, and approximately $2.3
million in 2004. In connection with the issuance of the preferred equity
interests in Tejas-Magnolia, another subsidiary of Tejas has contributed a
portion of the proceeds from sales under certain long-term natural gas sales
contracts to Tejas-Magnolia in exchange for common equity interests in
Tejas-Magnolia. This ongoing contribution supports the preferred distribution
obligations of Tejas-Magnolia during the eight-year term.

      As part of the Transok acquisition in June 1996 and the acquisition of
pipeline and related facilities from Exxon in September 1993, Tejas entered into
separate five-year operating leases with third parties for seven natural gas
processing plants ("Plant Lease") and a pipeline system ("System Lease"),
respectively. Lease payments under the two leases are adjusted quarterly based
upon the respective lessor's financing costs. However, Tejas has entered into
interest rate derivative agreements in a notional amount of $269.5 million to
fully hedge the effects of such adjustments on the required minimum lease
payments. The Plant Lease expires June 6, 2001 unless extended by mutual consent
of the lessor and lessee for up to two additional two-year periods. The System
Lease currently expires on September 14, 1998. Upon expiration of the leases,
Tejas, at its option, may either purchase the leased properties or pay a
termination fee of $106 million under the Plant Lease and $122.8 million under
the System Lease.

      Tejas' WCLSF requires the maintenance of cushion gas in order to sustain
anticipated operational requirements. Such cushion gas requirements have been
satisfied by a combination of natural gas purchased by Tejas and third party
natural gas stored in the facility. At December 31, 1996, Tejas had purchased
approximately 10.4 Bcf of cushion gas. In late 1994, Tejas entered into an
agreement with a third party whereby the third party agreed to purchase up to 35
Bcf of natural gas at a cost not to exceed $65 million and to store such gas in
the WCLSF. Such agreement was scheduled to expire in September 2000, however, as
described below, the agreement was recently amended and extended. In order to
secure Tejas' ability to purchase the gas from the third party, the agreement
provides for the payment by Tejas of a reservation fee to the third party which
is adjusted quarterly based upon the third party's financing costs. On certain
option dates, Tejas may elect to purchase specified volumes of the third party's
natural gas based upon market prices. Should Tejas decline to purchase the
natural gas, the third party may instruct Tejas to sell such volumes on the
third party's behalf. In such case, it will be necessary for Tejas to obtain
cushion gas through other means in order to meet the anticipated operational
requirements of the WCLSF. At December 31, 1996, the third party had 18.5 Bcf of
natural gas in storage at the WCLSF, which such party

                                       25
<PAGE>
purchased for $33.1 million. Based upon the volumes and rates in effect, Tejas
paid a reservation fee of approximately $1.1 million to the third party during
1996. Tejas owns, as a result of the Transok acquisition, the 26 Bcf capacity
Greasy Creek Storage Facility in Oklahoma. The Greasy Creek Storage Facility
requires the maintenance of cushion gas in order to sustain operational
requirements. Such gas is currently purchased from various suppliers.

      Effective January 16, 1997, the third party agreement described above was
amended and extended. The principal modifications to the agreement included the
extension of the contract expiration date to December 31, 2002 and, at Tejas'
option, an increase in the maximum volume of natural gas that may be stored in
Tejas' facilities, including the Greasy Creek Storage Facility, to 70 Bcf.

RISK MANAGEMENT ACTIVITIES

      In order to hedge the interest rate risks associated with Tejas' financing
activities (including operating lease obligations), Tejas frequently enters into
interest rate derivative agreements with financial institutions. While the
interest rate derivatives eliminate the risks associated with increases in the
floating interest rates of Tejas' obligations, the derivatives also eliminate
the opportunities associated with reductions in such floating interest rates.
Payments received or made by Tejas under such interest rate derivatives are
recorded as reductions to or increases in interest expense or rent expense, as
applicable, over the life of the interest rate derivative instrument. As of
December 31, 1996, Tejas had a total notional amount of $700 million of interest
rate derivatives for hedging purposes with a maximum weighted average fixed rate
of 6.2% excluding Tejas' average borrowing cost over LIBOR. The weighted average
life of the interest rate derivative hedging transactions is approximately 4.9
years.

      Tejas uses derivative financial instruments (primarily futures, swaps and
other contracts) as an extension of its commercial natural gas purchases and
sales and to hedge price exposure, including location and pricing basis, of its
storage and exchange gas inventories, commitments, and certain anticipated
transactions. While the derivative financial instruments are intended to reduce
the risks associated with unfavorable changes in such prices, the derivative
financial instruments also reduce the opportunities associated with favorable
changes in market prices. Any increases or decreases in the market value of such
derivative transactions are deferred and accounted for as part of the
transactions or activities being hedged. Tejas' interest rate and other
derivative agreements are with established exchanges, energy companies, and
major financial institutions, and Tejas believes that its counterparties will be
able to satisfy their contractual obligations. Coral engages in similar
derivatives transactions for its own account. Transok has historically entered
into anticipatory hedges for gas storage and gas processing. The methodology
used could result in Transok's having open positions in anticipation of future
requirements. See Notes 5 and 7 of "Notes to Consolidated Financial Statements"
for additional information with respect to Tejas' derivative transactions.

GROWTH STRATEGY

      In the normal course of business, Tejas regularly reviews opportunities
for the possible acquisition of additional natural gas pipelines and companies
that own natural gas pipelines. When potential acquisition opportunities are
deemed to be consistent with Tejas' growth strategy, bids or offers in amounts
and with terms acceptable to Tejas may be submitted. It is uncertain whether any
such bids or offers which may be submitted by Tejas would be acceptable to the
sellers of such acquisition targets. In the event of a future significant
acquisition, Tejas will likely require additional financing in connection
therewith.

OUTLOOK

      Tejas' 1996 results of operations were favorable when compared to 1995.
Tejas believes there are more opportunities available for future growth and
continued expansion of operations. The Transok 

                                       26
<PAGE>
acquisition provided Tejas with the opportunity to increase the sale of natural
gas to certain new markets in Oklahoma and to increase the flow of natural gas,
within the state, West to East. Proposed rules and regulations in Oklahoma may
open significant additional industrial end-user and city gate markets to
competition. These proposals, if passed or adopted, would present Transok with
opportunities to compete for supply arrangements with customers not previously
available to Transok. At the same time, these proposals and competitive bidding
procedures that are being implemented by electric utilities expose Transok to
the risk that other pipeline and marketing companies will seek to compete for
Transok's existing supply and transportation arrangements with utilities, such
as Public Service Company of Oklahoma ("PSO"). Although Transok presently
transports substantially all of the natural gas requirements for PSO's gas-fired
power stations in Oklahoma, competitors will begin transportation of natural gas
for PSO in 1998. While no prediction can be made as to the continuation of the
favorable impact of Coral on Tejas' prospects, Tejas believes that over the next
several years Coral should be in a position to take advantage of the unutilized
capacity in Tejas' major long-distance transmission lines. In addition, the
large number of interconnects between Tejas' pipelines and other intrastate and
interstate pipelines have the potential to become important supply points for
Coral. The capital invested by Tejas at the WCLSF since September 1993 has
increased the availability of natural gas and the operational flexibility of the
WCLSF. This flexibility permits Tejas to sell approximately 25 Bcf of additional
natural gas volumes annually out of this storage facility and to provide
additional daily storage injection and withdrawal capabilities to accommodate
the seasonal needs of customers. Further development of the WCLSF is possible
and Tejas will continue to monitor and review the economic benefit of such
development. There can be no assurance that market conditions, including the
average cost of natural gas held in storage, will always be conducive to
maintaining the current level of profitability. Tejas has historically shown the
ability to adapt to changing operational requirements and capitalize on new
market opportunities. Although the foregoing factors present Tejas with
opportunities to grow and expand, there can be no assurance that such factors
will result in future growth and expansion of Tejas' operations, revenues or
earnings.

      In the last quarter of 1996, Tejas completed sales of three non-strategic
assets: a transmission and gathering system located in North Louisiana, a
processing plant and its related gathering system in North Central Oklahoma and
an interest in a partnership which owned and operated oil and gas wells in West
Oklahoma. The majority of the proceeds from these transactions were used to
reduce the commitment level and repay indebtedness under the Transok Credit
Facility. Tejas has refinanced the borrowings under the Transok Credit Facility
(which was to mature on December 31, 1997) with interest rates and payment terms
favorable to Tejas (when compared to the terms of the original Transok Credit
Facility). Because of the many opportunities Tejas believes are available for
future growth and continued expansion of operations, Tejas anticipates using
substantially all of its available cash in 1997 and 1998 for capital
expenditures and acquisitions. To enhance throughput on Transok's pipeline
system, Tejas began construction of a 24-inch pipeline project, which includes
eight additional compressors. Capital expenditures for 1997, including the
Transok expansion project, are anticipated to be approximately $180 million, of
which Tejas has committed contractual obligations of approximately $50 million.
Actual capital expenditures may vary from budgeted amounts due to many factors.

      The statements included in this Report on Form 10-K regarding future

changes in laws and regulations to which Tejas is subject, the cost and effects
of legal and administrative claims and proceedings against Tejas or its
subsidiaries or which may be brought against Tejas or its subsidiaries,
conditions in the capital markets utilized by Tejas to access capital to finance
operations, Tejas' ability to develop expanded markets and product offerings as
well as maintain existing markets, energy prices, competition from other
pipelines and alternate fuels, the general level of natural gas 

                                       27

and petroleum product demand and weather conditions, among other things, and
other risks and uncertainties described in this Report on Form 10-K and in
Tejas' other filings with the Securities and Exchange Commission. Further,
natural gas prices, which directly impact transportation and gathering and
processing throughput and operating profits, may fluctuate in unpredictable
ways. Should one or more of these risks or uncertainties materialize, or should
underlying assumptions prove incorrect, actual results may vary materially from
those indicated.

      Tejas management knows of no trends or uncertainties that will impair
Tejas' ability to comply with its debt covenants or pay the dividends on the
9.96% Preferred Stock and 5 1/4% Preferred Stock.

INDEPENDENT AUDITORS' REPORT

The Board of Directors of
      Tejas Gas Corporation:

      We have audited the accompanying consolidated balance sheets of Tejas Gas
Corporation and its subsidiaries ("Tejas") as of December 31, 1996 and 1995, and
the related consolidated statements of earnings, stockholders' equity and cash
flows for each of the three years in the period ended December 31, 1996. Our
audits also included the financial statement schedule listed in the Index at
Item 8. These financial statements and the financial statement schedule are the
responsibility of Tejas' management. Our responsibility is to express an opinion
on the financial statements and the financial statement schedule based on our
audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Tejas as of December 31, 1996
and 1995, and the results of its operations and its cash flows for each of the
three years in the period ended December 31, 1996 in conformity with generally
accepted accounting principles. Also, in our opinion, the financial statement
schedule, when considered in relation to the basic consolidated financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              FOR THE YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

1.  ORGANIZATION

      Tejas Gas Corporation ("Tejas") was organized in 1988 by Hamilton Oil
Corporation ("HOC") for the purpose of holding the capital stock of Tejas Gas
Corp. ("Tejas Gas"). Tejas Gas was incorporated in 1967 and had been an indirect
wholly owned subsidiary of HOC since 1979. On December 27, 1988, Tejas' stock
was distributed to the stockholders of HOC in the form of a spin-off and Tejas
became an independent, publicly traded company. Unless the context indicates
otherwise, the term "Tejas" includes Tejas Gas Corporation and its subsidiaries.

      Tejas is a major intrastate natural gas pipeline company engaged in the
business of purchasing, gathering, processing, treating, storing, transporting
and marketing natural gas. Tejas' operations are situated primarily in the major
gas producing areas in Oklahoma, South Texas, East Texas and the Texas and
Louisiana Gulf Coast regions, with additional facilities located in West
Virginia. Tejas is a holding company that conducts operations through four
principal second tier subsidiaries, Tejas Gas, Acadian Gas Corporation
("Acadian"), Tejas Natural Gas Company ("TNGC") and, since June 1996, Transok,
Inc. ("Transok"). Tejas-Acadian Holding Company ("TAHC"), a wholly owned first
tier subsidiary of Tejas, was organized in December 1994 and owns the capital
stock of each of Tejas Gas, Acadian and TNGC. Tejas Transok Holding Company
("TTHC"), a wholly owned first tier subsidiary of Tejas, was organized in May
1996 and owns the capital stock of Transok (see "ACQUISITION" as described in
Note 3). Tejas Coral Holding Company ("TCHC"), formerly Tejas Alliance Holding
Company, a wholly owned first tier subsidiary of Tejas, was organized in July
1995 to hold an interest in Coral Energy, L.P. ("Coral", formerly Coral Energy
Resources, L.P.) an energy marketing joint venture with Shell Oil Company
("Shell").

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      BASIS OF PRESENTATION - The accompanying consolidated financial statements
include the accounts of Tejas and its majority and wholly owned subsidiaries.
Investments in companies in which Tejas' ownership interest ranges from 20 to 50
percent and Tejas exercises influence over operating and financial policies are
accounted for using the equity method. Other investments are accounted for using
the cost method. All significant intercompany balances and transactions have
been eliminated in consolidation. In connection with the preparation of these
financial statements, management was required to make estimates and assumptions
that effect the reported amount of assets, liabilities, revenues, expenses and
disclosure of contingent liabilities. Actual results could differ from such
estimates.

      Certain amounts in the consolidated financial statements for periods prior
to 1996 have been reclassified to conform to the current presentation.

      CASH AND CASH EQUIVALENTS - Cash and cash equivalents consist of all cash
balances and highly liquid investments which have an original maturity at
purchase of three months or less.

      EXCHANGE GAS - Exchange gas volumes receivable are valued at the lower of
cost or market at the end of each period. Exchange gas volumes payable are
recorded at market value at the end of each period.

      STORAGE GAS INVENTORY - Storage gas inventory is valued at the lower of
cost or market at the end of each period. Natural gas is removed from inventory
at weighted average cost.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

      DERIVATIVES - Realized gains and losses on hedges of existing assets or
liabilities are deferred and are ultimately recognized in income as part of the
carrying amounts of the related assets or liabilities. Gains and losses related
to qualifying hedges of firm commitments or anticipated transactions also are
deferred and are recognized in income or as adjustments of carrying amounts when
the hedged transaction occurs.

      PROPERTY, PLANT AND EQUIPMENT - Property, plant and equipment is stated at
cost. Additions, improvements and major renewals are capitalized. Maintenance,
repairs and minor renewals are expensed as incurred.

      The cost of property sold or retired is credited to the asset account, and
the related depreciation is charged to the accumulated depreciation account.
Profit or loss resulting from the sale or retirement is included in earnings.

      Depreciation of property, plant and equipment is provided on a
straight-line basis over the estimated useful lives of the assets as follows:

           ----------------------------------------------------------
            Buildings ..............................   25 years
            Natural gas systems, storage facilities,
               processing plants and treating plants   10 - 46 years
            Other equipment ........................   4 - 15 years
           ----------------------------------------------------------

      Effective July 1, 1996, Tejas reevaluated the estimated useful lives of
its operating assets to better reflect the economic lives for which these assets
will remain in service. The effect of the change in lives, the majority of which
occurred as a result of an increase in the lives for natural gas transmission
lines, resulted in an increase in net income available to common stockholders of
approximately $1.1 million or $.06 per share for the year ended December 31,
1996.

      On January 1, 1996, Tejas implemented Statement of Financial Accounting
Standards ("SFAS") No. 121 ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF. SFAS No. 121 requires that
long-lived assets and certain identifiable intangibles to be held and used by an
entity be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable. Certain
long-lived assets and certain identifiable intangibles to be disposed of must be
reported at the lower of carrying amount or fair value less cost to sell. The
implementation of SFAS No. 121 had no impact on Tejas' financial statements.

      CAPITALIZED INTEREST - Interest on funds used to finance construction of
assets is capitalized and amortized over the productive lives of the related
assets. All other interest is charged to expense as incurred. During 1996 and
1994 Tejas capitalized interest of $1.1 million and $.4 million respectively. No
interest was capitalized in 1995.

      GOODWILL - The excess of the acquisition costs over the fair value of
purchased assets, arising from the acquisition of Tejas Gas by HOC in 1978, is
recorded as goodwill and is being amortized $467,000 annually on a straight-line
basis over 40 years. At December 31, 1996 and 1995, the accumulated amortization
of goodwill was $8.9 million and $8.4 million, respectively. Tejas periodically
reviews the carrying value of goodwill in relation to the current and expected
operating results of Tejas Gas in order to assess whether there has been a
permanent impairment of goodwill.

                              TEJAS GAS CORPORATION

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

      MINORITY INTERESTS - Minority interests consist of preferred membership
units of a subsidiary of $45.3 million (see Note 10) and minority interests of
$9.3 million in Tejas' majority owned subsidiaries.

      REVENUES - Customers are invoiced and the related revenue is recorded as
natural gas deliveries are made.

      INCOME TAXES - Tejas accounts for income taxes in accordance with SFAS No.
109. Deferred income taxes are recorded for the effects of temporary differences
between financial and taxable income.

      EARNINGS PER COMMON SHARE - Earnings per common share are based upon the
weighted average number of shares of Common Stock and common stock equivalents,
if dilutive, outstanding during the year. Common stock equivalents consist of
shares issued assuming all stock options are exercised using the treasury stock
method. The difference between earnings per common share on a primary and a
fully diluted basis is not significant.

      Earnings per common and common equivalent share amounts and average shares
entering into such computation for 1996 and prior periods have been restated to
reflect the three-for-two stock split of Tejas' common stock effected in the
form of a stock dividend authorized in March 1993, the stock dividend of
one-tenth of one share of Common Stock for each share of Common Stock
outstanding authorized in July 1995 and the three-for-two stock split of common
stock effected in the form of a stock dividend authorized in April 1996.

      STOCK BASED COMPENSATION - In October 1995, the Financial Accounting
Standards Board ("FASB") issued SFAS No. 123 ACCOUNTING FOR STOCK BASED
COMPENSATION. SFAS No. 123 defines a fair value method of accounting for
employee stock options and similar equity instruments. This statement is
effective for fiscal years beginning after December 15, 1995. As allowed by SFAS
No. 123, Tejas will continue to measure compensation cost for its plans using
the intrinsic value method of accounting prescribed by Accounting Principles
Board Opinion No. 25 ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES with a pro forma
disclosure of any difference between compensation cost determined by using the
intrinsic value method and the related cost measured by using the fair value
method (see Note 12).

3.  ACQUISITION

TRANSOK, INC.

      On June 6, 1996, Tejas, through its recently formed wholly owned
subsidiary, TTHC, acquired Transok (the "Transok acquisition") from Central and
South West Corporation ("CSW"). Immediately prior to the acquisition, CSW sold
seven natural gas processing plants (the "Transok Plants") to an unrelated third
party lessor (the "Lessor"), which in turn leased these facilities (the "Lease")
to a subsidiary of Tejas (the "Lessee").

      Transok operates intrastate natural gas pipeline systems in Texas,
Oklahoma, and Louisiana and is one of the largest processors of natural gas in
Oklahoma. At the time of the acquisition, Transok's operations included: (i)
approximately 7,000 miles of gathering and transmission pipelines in Texas,
Oklahoma and Louisiana with 2.3 billion cubic feet ("Bcf") of natural gas per
day of pipeline capacity; (ii) eight natural gas processing plants, of which
seven are being leased to a subsidiary of Tejas, with total

                                       37
<PAGE>
                              TEJAS GAS CORPORATION

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

processing capacity of 564 million cubic feet ("MMcf") per day of natural gas;
(iii) a 26 Bcf capacity natural gas reservoir storage facility with 300 MMcf per
day of withdrawal and 200 MMcf per day of injection capacity; and (iv) 1.4
trillion cubic feet of connected third-party natural gas reserves. As described
below, Tejas subsequently sold approximately 2,100 miles of gathering and
transmission lines and a processing plant acquired in the Transok acquisition.

      The total purchase price received by CSW at closing was $690 million in
cash, of which $565 million was paid by Tejas and $125 million was paid by the
Lessor to acquire the Transok Plants. In addition, as part of the transaction,
Transok retained $200 million of long-term debt. To finance the cash
requirements for the Transok acquisition, Tejas borrowed (i) $178 million under
its existing credit facilities and (ii) $387 million, net of a $38 million
voluntary prepayment, under a new $425 million credit agreement (the "Transok
Credit Facility") (see Note 5).

      In connection with the acquisition of Transok, CSW sold seven natural gas
processing plants to the Lessor for $125 million. Tejas, through a wholly owned
subsidiary, leased the Transok Plants from the Lessor for a five-year term with
lease payments adjusted quarterly based upon the Lessor's financing costs. Tejas
has entered into interest rate derivative agreements in a notional amount of
$125 million to hedge the effects of such adjustments on the required minimum
lease payments. In addition, under the Lease, the Lessee has the option to
extend the term of the Lease for up to two additional two year periods, subject
to approval by the Lessor, and to purchase all of the Transok Plants at any time
for $125 million. If by the end of the Lease term, the Lessee has not exercised
its option to purchase the Transok Plants, it is obligated to pay the Lessor a
termination fee of approximately $106 million. However, the Lease contains a
provision that reduces the termination fee to the extent the proceeds from the
Lessor's subsequent sale of the Transok Plants exceed $19 million. The Lease
also provides the Lessee the option to purchase, at any time during the Lease
term, one or more of the Transok Plants for an aggregate amount not exceeding
$31 million, with corresponding reductions to the $106 million termination fee
and the $19 million threshold amount.

      The acquisition of Transok was accounted for as a purchase and the
purchase price was allocated to the acquired assets and liabilities based upon
the estimated fair value of such assets and liabilities as of June 6, 1996. The
Lease is for a five-year term and is accounted for as an operating lease. The
allocation of the purchase price is preliminary, as valuation and other studies
have not been finalized. It is not expected that the final allocation of the
purchase price will produce materially different results from those presented
herein. The results of operations for the assets acquired or leased as a result
of the Transok acquisition are included in the accompanying financial statements
for the period subsequent to June 6, 1996.

      During the last quarter of 1996, Tejas completed the sales of three
non-strategic assets: a transmission and gathering system located in Northern
Louisiana, a processing plant and its related gathering system in North Central
Oklahoma and an interest in a partnership which owned and operated oil and
natural gas wells in Western Oklahoma. These transactions, none of which
resulted in a gain or loss, generated cash proceeds of approximately $110
million, most of which was used to reduce the commitment level and repay
indebtedness under the Transok Credit Facility.

      The unaudited pro forma condensed statements of earnings which follow
represent consolidated results of operations as if the Transok acquisition had
been consummated at the beginning of each year presented. Pro forma adjustments
have been made to the historical amounts for the entities and operations

                                       38

acquired for operating expenses, depreciation and amortization, general and
administrative expenses, interest expense and related tax effects. Such amounts
do not include the pro forma effects of the issuance of common stock (see Note
12), which were integral to Tejas' financial condition prior to and after the
Transok acquisition.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

TAHC AND TNGC FACILITIES

      Effective January 12, 1995, Tejas amended its credit facilities to roll-up
a majority of the existing bank debt of its three principal operating
subsidiaries into a single, $455 million, eight-year, revolving credit facility
at a newly formed subsidiary, TAHC. One of the subsidiaries, TNGC, retained a
$25 million working capital facility with terms and conditions substantially
similar to the rolled-up facility. The two facilities combined (the "Credit
Agreements") provide TAHC and its subsidiaries with $480 million in borrowing
capacity. The Credit Agreements bear interest at Tejas' option, based on either
the prime rate or LIBOR. The margins over LIBOR that TAHC and TNGC must pay
vary, depending on TAHC's funded debt to capitalization ratio, from a minimum of
0.5% to a maximum of 1.25%. Based on borrowings at December 31, 1996, of $443.8
million, and after considering restrictions to provide for a $10 million letter
of credit and borrowings under its money market credit lines (offset by cash
available pursuant to the terms of such money market credit lines),
approximately $26.2 million of additional borrowings were available under these
amended facilities. Additionally, at year-end, based upon TAHC's funded debt to
capitalization ratio, the Credit Agreements bore interest, at Tejas' option, of
prime or LIBOR plus 0.75%. Under the terms of the Credit Agreements, after two
years, the revolving credit facilities will convert into six-year reducing
revolvers unless extended at the option of the lenders. During the fourth
quarter of 1996 the lenders under the Credit Agreements agreed to extend by one
year both the maturity date and the period in which commitment reductions
commence. As such, commitment reductions of $15 million per quarter are
scheduled to begin March 31, 1999 with the final remaining commitment reduction
to occur on December 31, 2004. Based upon the current terms of the Credit
Agreements and the outstanding principal balances thereunder at December 31,
1996, no principal payments are required until the year 1999.

TRANSOK FACILITY

      In connection with the Transok acquisition, Tejas initially borrowed $387
million, net of a voluntary prepayment, under the Transok Credit Facility and
assumed $200 million of Transok medium term notes ("MTN's"). Additional funds of
$178 million were borrowed under the TAHC Credit Facility (see "TAHC and TNGC
Facilities" above). The outstanding balance under the Transok Credit Facility
was reduced to approximately $196 million by year-end 1996 primarily due to the
application of proceeds received by Tejas subsequent to the Transok acquisition
from the sale of common stock and the sale of certain non-strategic assets.
During the fourth quarter of 1996, the Transok Credit Facility was amended (the
"Amended Transok Credit Facility"). The principal changes included extending the
maturity date from December 31, 1997 to December 31, 2004, lowering the interest
rate margins over LIBOR, subject to a minimum margin for a limited period of
time, and setting the commitment amount at $275 million. The Amended Transok
Credit Facility bears interest, at Tejas' option, based upon either the prime
rate or LIBOR. Depending upon Transok's funded debt to capitalization ratio, the
margins over LIBOR that Transok must pay vary from a minimum of 0.5% to a
maximum of 1.25%. Based upon the December 31, 1996 outstanding balance of
approximately $196 million, the Amended Transok Credit Facility had available
borrowings of approximately $79 million and bore interest rates, at Tejas'
option, of prime or LIBOR plus 1.0%. Under the terms of the Amended Transok
Credit Facility, after two years, the revolver will, unless extended at the
option of the lenders, convert into a six year reducing revolver. Commitment
reductions of approximately $8.6 million per quarter are currently scheduled to
begin March 31, 1999 with the final remaining commitment reduction to occur on
December 31, 2004. Nevertheless, based upon the current terms of the Amended
Transok Credit Facility and the outstanding principal balance thereunder at
December 31, 1996, no principal payments are required until the year 2001.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

MEDIUM TERM NOTES

      In connection with the Transok acquisition, Tejas assumed $200 million in
MTN's. The MTN's bear interest at fixed rates which, on a weighted average
basis, currently approximates 7.7%. The maturity dates of the MTN's vary with
the longest dated MTN's due to mature in 2023 with interest rates ranging from
6.60% to 8.96%.

      The MTN's are secured by certain intercompany notes, by the capital stock
of all of Transok's subsidiaries and certain partnership interests held by
Transok, and are guaranteed by such subsidiaries.

INDUSTRIAL DEVELOPMENT BONDS

      In 1990, a Tejas subsidiary issued two notes in the aggregate amount of
approximately $11.2 million related to the issuance of Industrial Development
Refunding Revenue Bonds ("IDRRBs") by Lewis and Pleasants Counties, West
Virginia, and called for redemption of previously outstanding notes and related
Industrial Development Revenue Bonds ("IDRBs") of those counties in the
aggregate amount of approximately $11.2 million. As of December 31, 1996
approximately $10.2 million of notes and IDRRBs were outstanding with a weighted
average interest rate of 8.7%, including bank fees. Such notes require annual
principal payments of $2 million in each of the years 1997 through 2000, $1.6
million in 2001 and $.6 million in 2002. The notes are secured by bank letters
of credit which in turn are secured by mortgages on two natural gas processing
plants located in West Virginia. The notes are also subject to certain covenants
and require that Tejas' subsidiaries, TAHC and Gulf Energy Gathering &
Processing Corporation, maintain certain financial standards.

MONEY MARKET CREDIT LINES

      Tejas has uncommitted money market credit lines which allow Tejas to
borrow up to $50 million for periods of up to two months. Any such borrowings
are unsecured and may be extended for additional periods if agreed to by the
lenders. At December 31, 1996, Tejas had no outstanding borrowings under the
money market credit lines. Tejas has agreed to maintain funds, including, but
not limited to, availability under the Credit Agreements and the Amended Transok
Credit Facility, sufficient to repay borrowings under the money market credit
lines and accordingly, any outstanding balances are classified as long-term
debt.

INTEREST RATE DERIVATIVES

      Tejas has entered into various interest rate derivative agreements as a
means of hedging interest exposure on its floating rate debt and operating lease
obligations. At December 31, 1996 Tejas had interest rate derivative agreements
in a notional amount of $700 million (see Note 7). Of this amount, $455.5
million hedges a like amount of Tejas' debt to a maximum effective interest rate
of 6.4%. Of the $455.5 million, $50 million of the agreements expire in 1997,
$5.5 million expire in 1998, $75 million expire in 1999, and the remaining $325
million expire at various times no later than 2006. See Note 14 for information
concerning interest rate derivative agreements used to hedge floating operating
lease obligations. Although Tejas does not presently anticipate terminating any
of these agreements prior to their respective expiration dates, it monitors its
options available under prevailing market conditions.

      Additionally, in 1996, Tejas entered into interest rate derivative
agreements in a notional amount of $175 million. These agreements will convert a
like amount of Tejas' debt and/or operating lease obligations to an effective
interest rate of 6.7%. Of this amount, $150 million of the agreements became
effective in January 1997 and expire in January 2002. The remaining $25 million
become effective in January 1999 and expire in December 2001.

RESTRICTIVE COVENANTS

      Under the terms of the Credit Agreements, and the Amended Transok Credit
Facility, TAHC and Transok are required to maintain certain financial ratios.
The Credit Agreements and the Amended Transok Credit Facility each contain,
among other things, limitations related to the transfer of funds between TAHC
and its subsidiaries and Transok and its subsidiaries, the transfer of funds
between TAHC and Tejas and Transok and Tejas, and the sale of assets in excess
of specified amounts. The obligations under the Credit Agreements are secured by
the capital stock, partnership interests and various intercompany notes of all
material TAHC subsidiaries and partnerships (excluding the capital stock of
Acadian, but including the capital stock and partnership interests of the
material operating subsidiaries and partnerships of Acadian) and are guaranteed
by such subsidiaries and partnerships. The obligations under the Amended Transok
Credit Facility and the MTN's are secured by certain intercompany notes, and by

the capital stock of all of Transok's subsidiaries and certain partnership
interests held by Transok, and are guaranteed by such subsidiaries.

      The amount of loans, advances and dividends that may be made to Tejas from
TAHC, TNGC and Transok under the Credit Agreements and the Amended Transok
Credit Facility is subject to certain limitations. At December 31, 1996, the
permitted amounts of such payments were $204.1 million. In general, such
payments may be adjusted by (i) a percentage of consolidated quarterly net
earnings or losses of TAHC, TNGC and Transok, (ii) certain investments, and
(iii) any cumulative aggregate payments.

      The MTN's are subject to certain covenants with which Tejas expects to be
able to comply in the ordinary course of business.

      Deferred income taxes typically reflect (a) the net tax effects of
temporary differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes, and
(b) alternative minimum tax, net operating loss and tax credit carryforwards.
Significant components of Tejas' net deferred income tax liability are as

      At December 31, 1996 and 1995, $2.1 million and $2 million, respectively,
of deferred income tax assets were classified as current assets on the
Consolidated Balance Sheets. Included in "Other" above for 1996 is $9.8 million
of deferred tax assets related to accrued liabilities not deductible in the
current year. No valuation allowances were required for deferred income tax
assets at either December 31, 1996 or 1995.

      Tejas made income tax payments in 1996, 1995 and 1994 of $10.4 million,
$7.4 million and $5.1 million, respectively. As of December 31, 1996, Tejas had
income tax receivable of $6.2 million included in "Prepaids and other current
assets" included in current assets on the consolidated balance sheet.

7.  FINANCIAL INSTRUMENTS

      The estimated fair value amounts of Tejas' financial instruments have been
determined by Tejas using available market data and valuation methodologies.
Fair value represents the amount at which the instruments could be exchanged in
a current transaction between willing parties. Judgement is necessarily required
in interpreting market data and the use of different market assumptions or
estimation methodologies may affect the estimated fair value amounts.

- --------------------------------------------------------------------------------------
</TABLE>

LONG-TERM DEBT

      Tejas' revolving credit agreements and money market credit lines bear
floating interest rates at current market levels and therefore carrying values
in the financial statements approximate fair value. The estimated values of the
industrial development bonds and the MTN's are based upon interest rates at
December 31, 1996 for new issues with maturities which approximate the original
life of the existing bonds.

INTEREST RATE DERIVATIVE AGREEMENTS

      At December 31, 1996 and 1995, Tejas had entered into interest rate
derivative agreements, with a notional amount of $700 million and $325 million,
respectively, as a means of hedging floating interest rate exposure related to
its revolving credit facilities and operating lease obligations ($269.5 million
in 1996 and $144.5 in 1995). The fair value of interest rate derivative
agreements is based upon approximated termination values obtained from third
parties. The negative fair value at December 31, 1996 is the estimated amount
Tejas would pay if it canceled the contracts or transferred them to other
parties.

COMMODITY FUTURES AND SWAPS

      Tejas uses derivative financial instruments (primarily futures, swaps and
other contracts) as an extension of its commercial natural gas purchases and
sales and to hedge price exposure, including location

                                       45

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)


and pricing basis, of its storage and exchange gas inventories, commitments, and
certain anticipated transactions. At December 31, 1996 Tejas had a realized but
unrecognized loss of $5.2 million and an unrealized loss of $2.8 million on
futures contracts. At year-end, open swap contracts where Tejas pays one price
basis in exchange for another covered a notional volume of 169.5 Bcf and extend
into December 1998. The fair value of these swap contracts at December 31, 1996
was $1.2 million payable to Tejas based upon estimated termination values. The
realized but unrecognized futures loss of $5.2 million, unrealized futures loss
of $2.8 million and unrealized swaps gain of $1.2 million have been incurred in
conjunction with Tejas' storage arbitrage program or anticipated sales or
purchases of natural gas and either have been offset or will be offset by
transactions involving the physical delivery of natural gas.

CREDIT RISK

      While notional contract amounts are used to express the magnitude of
interest rate derivative or commodity swap agreements, the amounts potentially
subject to credit risk, in the event of nonperformance by third parties, are
substantially smaller. Tejas does not anticipate any material impact to its
results of operations as a result of nonperformance by third parties as these
agreements are with established exchanges, energy companies, and major financial
institutions. Under certain circumstances, commodity swap agreements may require
the parties to post letters of credit issued by financial institutions
acceptable to the counterparty to satisfy margin requirements.

8.  UNCONSOLIDATED ENTITIES

      Tejas owns an interest in several unconsolidated entities the summary of
which is as follows:

CORAL ENTITIES

      Tejas, through subsidiaries of TCHC, holds one-half interest in Coral, an
energy marketing venture between Tejas and Shell which commenced operations in
November 1995. Coral is a Delaware limited partnership formed in September 1995
to market natural gas and power for Tejas and Shell. Prior to January 1997,
Coral was owned one-third by subsidiaries of Tejas and two-thirds by
subsidiaries of Shell. Effective January 1997, Tejas purchased from Shell an
additional 162/3% interest in Coral thereby increasing its ownership to 50%.
Shell Canada Limited of Calgary, Alberta may acquire an equity interest in Coral

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

in a transaction expected to close in early 1997. This should enhance Coral's
ability to expand its operations into Canada.

      Through Coral, Tejas sells natural gas to electric utilities, local
distribution companies, industrial end-users, marketing affiliates of other
pipeline companies and gas marketing companies. Tejas' electric utility and
industrial customers normally consume the natural gas in their own operations
while local distribution companies, pipeline affiliated customers, and gas
marketing customers generally resell the natural gas. Tejas' natural gas sales
are made pursuant to both long-term contracts which range in term from one to 20
1/2 years and short-term agreements which generally range from one month to one
year in duration. An interest in Tejas' long-term sales contracts, has been
contributed to Coral.

      Coral conducts natural gas marketing activities for Tejas and Shell. In
addition, Coral has received regulatory approval to market electricity in
wholesale markets and commenced such activities in the third quarter of 1996.
Coral initially began marketing 3.7 Bcf per day of Tejas and Shell natural gas
volumes. As of December 31, 1996, sales of natural gas were in excess of 6.1 Bcf
per day. Tejas provides Coral access to Tejas' natural gas pipelines which have
interconnects with other pipelines serving the U.S. and access to gas supplies
from Tejas' storage facilities and gathering and transmission systems located in
Texas, Oklahoma and Louisiana. Shell dedicates approximately 2 Bcf per day of
gross natural gas production and approximately 5.5 trillion cubic feet of
natural gas reserves. Tejas has committed to Coral substantially all of its
natural gas supply, and Shell has committed to Coral substantially all of its
natural gas production in the United States (excluding Alaska and Hawaii). Coral
was initially staffed with employees from Tejas and Shell. In addition, Tejas
provides intrastate marketing expertise, and Shell provides interstate marketing
expertise, as well as treasury and administrative support services. Coral has
also entered into a contractual arrangement with Bankers Trust to assist in
providing a variety of specially tailored risk management services.

      Tejas and Shell have each contributed cash and economic interests in
natural gas sales contracts to Coral for their respective interests. Each
partner has received equity credit for natural gas contract commitments to the
partnership. If actual volumes and margins from these contracts fail to meet
targeted contract levels, the responsible partner is subject to make-up
payments. If Coral is unable to take all of the natural gas tendered for
delivery by the partners, Coral is obligated to pay for such natural gas at the
price that would have otherwise been applicable, mitigated by the amount
obtained from any sales of such natural gas to third parties.

EVANGELINE ENTITIES

      In December 1991, Tejas and other parties formed Evangeline Gas Pipeline
Company, L.P., a limited partnership ("Evangeline") and Evangeline Gas Corp.
("EGC"). Tejas owns a 45% limited partnership interest in Evangeline and 45% of
the common stock of EGC. EGC is the general partner of Evangeline and owns a 10%
general partnership interest.

      Although the December 1991 projections for Evangeline anticipated losses
during the first four years of operations, at no time during the anticipated
20-year life of Evangeline did the projected cumulative losses exceed the agreed
Tejas sharing levels. By agreement, Tejas did not initially bear any losses in
the Evangeline entities until cumulative losses totaled $7.7 million. After the
$7.7 million threshold was reached, Tejas' interests in the Evangeline entities
bore 45% of all losses until cumulative losses totaled $9.7 million, and bears
100% of all losses until cumulative losses total $19.2 million. Evangeline is
not permitted to make distributions to its partners until its debt is
extinguished. At December 31, 1996 and 1995, cumulative losses of the Evangeline
entities totaled $12.5 million and $11.2 million, respectively. While Tejas has
incurred losses during 1996 and 1995 from Evangeline, Evangeline's cash flow
from operating activities during that time period has been sufficient to service
debt and meet other cash requirements.

GULF COAST NATURAL GAS COMPANY

      In January 1992, Tejas and another company formed a general partnership,
Gulf Coast Natural Gas Company ("GCN") which is engaged in the natural gas
pipeline business. Tejas purchased a 50% capital

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

interest in the partnership over a 12-month period at a total cost of $19.4
million. Tejas invested $.3 million in GCN for its share of capital expenditures
in 1996 and $.1 million in 1995.

      By agreement, Tejas receives 70% of the cash operating income of GCN until
December 31, 1998 and 50% thereafter. Depreciation expense is shared evenly for
substantially all of the assets.

DOWNTOWN PLAZA II

      Transok Properties, Inc. holds a 50% undivided interest in the Downtown
Plaza II partnership. This partnership owns a twenty-eight story office building
in Tulsa, Oklahoma. Transok occupies approximately one-half of the building.
Downtown Plaza II generates cash flow from two major lessees including Transok.
Transok recognized $.3 million in equity earnings during 1996.

SUMMARIZED FINANCIAL INFORMATION

      Combined summarized financial information for all Tejas' unconsolidated
entities as of and for the years ended December 31, 1996 and 1995 is presented

10. PREFERRED MEMBERSHIP UNITS OF A SUBSIDIARY COMPANY

      On December 29, 1995, a subsidiary of Tejas, Tejas-Magnolia Energy, L.L.C.
("Tejas-Magnolia"), issued preferred equity interests to a third party in return
for a capital investment of $55 million. Tejas- Magnolia is required to make
preferred distributions to the third party which constitute a return on capital
(at an effective fixed after tax cost to Tejas of 4.2%) and return of capital
over an eight-year term. Annual distributions including returns on and of
capital of approximately $8.7 million are payable from 1997 through 2001 and
approximately $9.5 million in each of 2002 and 2003 and approximately $2.3
million in 2004. In connection with the issuance of the preferred equity
interests in Tejas-Magnolia, another subsidiary of Tejas has contributed a
portion of the proceeds from sales under certain long-term natural gas sales
contracts to Tejas-Magnolia in exchange for common equity interests in
Tejas-Magnolia. This ongoing contribution supports the preferred distribution
obligations of Tejas-Magnolia during the eight-year term. Required return of
capital for 1997 of $5.4 million is classified as current maturities of
long-term obligations.


11. PREFERRED STOCK

      At December 31, 1996 and 1995, Tejas had authorized 6,000,000 shares of $1
par value preferred stock. The preferred stock may be issued in one or more
series and the Board of Directors will determine the specific terms and
conditions of each series in the event such shares are issued.

      In February 1993, Tejas completed the sale of 2,000,000 depositary shares,
each such depositary share representing one-tenth of a share of Tejas' 9.96%
Cumulative Preferred Stock (the "9.96% Preferred 

                                       50

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Stock"). Net proceeds from the sale of the 9.96% Preferred Stock totaled $48.2
million with $48 million initially used to repay indebtedness under a
subsidiary's $120 million reducing revolving credit facility which existed at
such time. Dividends on the 9.96% Preferred Stock are cumulative from the date
of original issuance and are payable quarterly, commencing May 1, 1993, in an
amount equal to $2.49 per annum per depositary share. The 9.96% Preferred Stock
is redeemable at Tejas' option at any time after February 1, 1998 at a
redemption price equal to $250 per share.

      In November 1993, Tejas completed the sale of 1,300,000 depositary shares,
each such depositary share representing one-fifth of a share of Tejas' 5 1/4%
Convertible Preferred Stock (the "5 1/4% Preferred Stock"). Net proceeds from
the sale of the 5 1/4% Preferred Stock totaled $62.8 million and were used to
repay substantially all of a $65 million term loan incurred in conjunction with
the properties purchased from Exxon Corporation. Dividends on the 5 1/4%
Preferred Stock are cumulative from the date of original issuance and are
payable quarterly, commencing February 1, 1994, in an amount equal to $2.625 per
annum per depositary share. Each share of 5 1/4% Preferred Stock is convertible,
in whole or in part, at any time, at the option of the holders thereof, into
shares of Common Stock at a conversion price of $42.4243 per share of Common
Stock (equivalent to a conversion rate of 1.1786 shares of Common Stock for each
depositary share). The 5 1/4% Preferred Stock is redeemable, at Tejas' option
(i) at any time after November 10, 2003, at a redemption price of $250 per
share, or (ii) at any time between November 10, 1996 and November 10, 2003 at
redemption prices which range from $259.19 to $251.31 per share.

      Both the 9.96% Preferred Stock and the 5 1/4% Preferred Stock rank, as to
dividends and liquidation, prior to Tejas' Common Stock. If the equivalent of
six quarterly dividends payable on either the 9.96% Preferred Stock or the 5
1/4% Preferred Stock is in arrears, then the number of directors of Tejas will
be increased by two and the holders of the classes of preferred stock with
dividends in arrears will be entitled to elect the two additional directors
until all dividends in arrears have been paid or declared and set apart for
payment. No arrearages currently exist.

12. COMMON STOCK

      On November 11, 1994, Tejas adopted a stockholders rights plan and
declared a dividend of one right (a "Right") for each share of Tejas' Common
Stock, par value $.25 per share (the "Common Stock"), outstanding as of the
close of business on November 22, 1994. The Rights, which under certain
circumstances entitle their holders to purchase one one-hundredth of a share of
Series C Junior Participating Preferred Stock, par value $1.00 per share, for an
exercise price of $200, will expire on November 11, 2004.

      The Rights are not exercisable until the earlier to occur of (i) 10 days
following the first date of public announcement that a person or group of
affiliated persons (an "Acquiring Person") has acquired beneficial ownership of
15% or more of the outstanding shares of Common Stock or such earlier date as a
majority of the Board of Directors shall become aware of the existence of an
Acquiring Person (the "Stock Acquisition Date") or (ii) 10 business days (or
such later date as may be determined by action of the Board of Directors prior
to such time as any person or group of affiliated persons becomes an Acquiring
Person) following the commencement of, or announcement of an intention to make a
tender offer or exchange offer, the consummation of which would result in the
beneficial ownership by a person or group of 15% or more of the outstanding
shares of Common Stock.

                                       51
<PAGE>
                             TEJAS GAS CORPORATION

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

      In the event that any person becomes an Acquiring Person, each holder of a
Right, other than Rights beneficially owned by the Acquiring Person (which will
thereupon become void), will thereafter have the right to receive upon exercise
of a Right at the then current exercise price of the Right, that number of
shares of Common Stock having a market value of two times the exercise price of
the Right. In the event that, after a person or group has become an Acquiring
Person, Tejas is acquired in a merger or other business combination transaction
or 50% or more of its consolidated assets or earning power are sold, each holder
of a Right other than Rights beneficially owned by an Acquiring Person (which
will have become void) will thereafter have the right to receive, upon the
exercise of the Right at the then current exercise price of the Right, that
number of shares of Common Stock of the person with whom Tejas has engaged in
the foregoing transaction which number of shares at the time of such transaction
will have a market value of two times the exercise price of the Right.

      At any time until ten days following the Stock Acquisition Date (subject
to extension by the Board of Directors), Tejas may redeem the Rights in whole,
but not in part, at a price of $.01 per Right.

      On April 11, 1996, the Tejas Board of Directors authorized a three-for-two
split of the Common Stock of Tejas effected in the form of a stock dividend
payable to stockholders of record as of April 26, 1996. All references to shares
issued and outstanding, average shares outstanding and earnings per share
included in the financial statements and accompanying notes and schedules have
been restated to give effect to the stock split. As a result of the stock split,
5,801,500 shares (net of 269 fractional shares repurchased) of Common Stock were
added to the 11,603,263 common shares outstanding at December 31, 1995. The par
value of the additional shares, approximately $1.5 million, has been transferred
from retained earnings to Common Stock. As a result of the stock split, the
conversion price of Tejas' 5 1/4% Convertible Preferred Stock was adjusted from
$63.6364 to $42.4243 (equivalent to an adjustment in the conversion rate from
 .7857 to 1.1786 shares of Common Stock for each depositary share representing a
one-fifth interest in a share of the 5 1/4% Convertible Preferred Stock). The
adjustment to the conversion price (and conversion rate) was effective as of
April 27, 1996. Additionally, options to purchase Common Stock under Tejas'
Stock Option Plans as well as option prices were adjusted as a result of the
Common Stock split.

      On July 19, 1995, Tejas' Board of Directors authorized a stock dividend of
one-tenth of one share of Common Stock for each share of Common Stock
outstanding payable to stockholders of record on July 27, 1995. All references
to average shares outstanding and earnings per share included in the financial
statements and accompanying notes for periods prior to the stock dividend have
been restated to give retroactive effect to the stock dividend. As a result of
the stock dividend, 1,052,908 shares (net of 422 fractional shares repurchased)
of Common Stock were added to the 10,533,303 common shares outstanding at June
30, 1995. The fair value of the additional shares at the declaration date, $52.8
million, was transferred from retained earnings to Common Stock and capital
surplus in the amount of $.3 million and $52.5 million, respectively. As a
result of the stock dividend, the conversion price of Tejas' 5 1/4% Preferred
Stock was adjusted from $70 to $63.6364 (equivalent to an adjustment in the
conversion rate from .7143 to .7857 shares of Common Stock for each depositary
share representing a one-fifth interest in a share of the 5 1/4% Preferred
Stock). The adjustment to the conversion price (and conversion rate) was
effective as of July 28, 1995. Additionally, options to purchase Common Stock
under Tejas' Stock Option Plans as well as option prices were adjusted as a
result of the Common Stock dividend.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

      On July 22, 1996, Tejas sold 3,075,000 shares of its Common Stock in an
underwritten public offering. Net proceeds to Tejas from the sale of the Common
Stock, approximately $102.8 million, were used to reduce indebtedness under the
$425 million Transok Credit Facility.

      In 1995, Tejas adopted the Director Stock Award Plan which was approved by
the stockholders at the annual meeting of stockholders on May 9, 1996. The
Director Stock Award Plan provides for the award of up to 45,000 shares of
Common Stock to nonemployee directors. Under the Director Stock Award Plan,
nonemployee directors are awarded newly issued shares of Common Stock on July 19
of each year equal to (i) $10,000 divided by (ii) the fair market value
(determined in accordance with such plan) per share of Common Stock on such date
(with cash in lieu of fractional shares). In addition, nonemployee directors
are entitled to elect to receive shares of Common Stock in lieu of their cash
annual retainer (currently $10,000).

      In 1988, Tejas adopted the Executive Officers Stock Option Plan (the
"Tejas Plan"), which provided for the granting of options for 1,651,652 shares
of Common Stock. During 1992, Tejas amended the Tejas Plan to include key
employees other than executive officers and to increase the number of shares
available for grant under the Tejas Plan by an additional 1,312,318 shares.
During 1996, options to purchase 441,551 shares of Common Stock were granted
under the Tejas Plan to executive officers and key employees at option prices
ranging from $30.83 to $39.22 per share. In 1992, Tejas implemented the Director
Stock Option Plan (the "Director Plan"), which provided for the granting of
options for 371,250 shares of Common Stock to directors of Tejas. Options to
purchase 37,125 shares of Common Stock were granted in 1996 under the Director
Plan at an option price of $36.67 per share. Since inception, no stock options
have been granted at below market prices at the date of the grant.

      The following table summarizes the status of outstanding stock options:

STOCK OPTION PLANS

      At December 31, 1996, Tejas had two stock-based deferred compensation
plans which are described below. Tejas applies Accounting Principles Board
("APB") Opinion 25 and related interpretations in

accounting for its plans. Accordingly, no compensation cost has been recognized
for its fixed stock option plans. Had compensation cost for Tejas' two
stock-based compensation plans been determined based on the fair value at the
grant dates for awards under those plans, consistent with the method of SFAS No.

      Under the 1992 Tejas Plan as amended ("Employee Plan"), Tejas may grant
options to its executive officers and key employees for up to approximately 3
million shares of Common Stock. Under the 1992 Director Stock Option Plan as
amended ("Director Plan"), Tejas may grant options to its outside directors for
up to 371,250 shares of Common Stock. Under both plans, the exercise price of
each option equals the fair market price of Tejas' Common Stock on the date of
grant. Options granted under the Employee Plan expire seven years after the date
of grant and may be granted at any time determined by the Stock Option
Committee. The Employee Plan options are exercisable at times fixed by the Stock
Option Committee. Options granted under the Director Plan expire seven years
after the date of grant and are granted annually on the first business day
following Tejas' Annual Meeting of Stockholders. Options granted under the
Director Plan become exercisable, on a cumulative basis, in five equal
installments, with the first installment becoming exercisable six months after
the date of the grant and the remaining four installments becoming exercisable
annually commencing on the first anniversary of the date of the grant.

      The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option-pricing model with the following weighted-average
assumptions for grants in 1995 and 1996, respectively: no dividend yield for all
years, expected volatility of 26 and 25 percent, risk-free interest rates of 6.9
and 5.7 percent for the Employee Plan options and 6.3 and 6.7 percent for the
Director Plan options; and expected lives of 6.6 and 6.9 years for the Employee
Plan options and 7 and 7 years for the Director Plan options.

13. COMMITMENTS AND CONTINGENCIES

THE LONG TRUST LITIGATION

      Tejas is a defendant or party in various lawsuits that have risen in the
ordinary course of Tejas' business. In particular, a subsidiary of Tejas is a
defendant in THE LONG TRUSTS V. TEJAS GAS CORP. ET. AL., 123rd Judicial District
Court, Panola County, Texas, filed March 1, 1989, in which plaintiffs assert
claims and allege damages for breach of contract and failure to take-or-pay for
natural gas pursuant to three natural gas purchase contracts. Plaintiffs allege
that, in addition to failing to take-or-pay for gas, Tejas breached (a) one of
the contracts by failing to take a minimum quantity of gas and to install and
maintain pipeline facilities sufficient to permit Tejas to meet its quantity
purchase obligations, and (b) all three contracts by failing to take gas in
quantities sufficient to enable plaintiffs to produce ratably with other
producers in a

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

common reservoir. In plaintiffs' Sixth Amended Original Petition filed June 6,
1995, the plaintiffs are seeking take-or-pay damages for the ten year period
1984-1994 in excess of $36 million, plus pre-judgment interest, post-judgment
interest, attorneys' fees and court costs and other unspecified actual damages.
In connection with their depositions in this matter, certain expert witnesses
retained by The Long Trusts have presented damage models purporting to show
approximately $60 million in take-or-pay damages and $70 million for failure to
take The Long Trusts' gas ratably. Management disputes The Long Trusts' claims
and believes that The Long Trusts' damage models are seriously flawed. On
January 6, 1993, the court entered an interlocutory summary judgment order
granting in part and denying in part plaintiffs' motions for summary judgment.
The court found, among other things, as a matter of law that (a) Tejas breached
the minimum take obligations under one of the contracts, (b) Tejas is not
entitled to any credits or offsets for natural gas purchased by third parties,
and (c) the "availability" of natural gas for take-or-pay purposes is
established by the delivery capacity testing procedures in the contracts.
Damages, if any, have not been determined. The effect of this order on Tejas'
case is unclear and Tejas has sought clarification and rehearing, but intends
nevertheless to defend its position aggressively.

      Because of the relationship between The Long Trusts contracts and certain
contracts between Tejas and Valero Transmission Company ("VTC"), and in order to
resolve existing and potential claims and disputes, Tejas, VTC and Valero
Transmission, L.P. ("VTLP") entered into an agreement, pursuant to which, among
other things, Tejas, VTC and VTLP would cooperate in the conduct of The Long
Trusts litigation, and VTC and VTLP would bear a substantial portion of the
costs of any appeal and of the amount of any nonappealable final judgment
rendered against Tejas. On April 15, 1994, the plaintiffs named VTC and VTLP
(collectively "Valero") as additional defendants to the lawsuit, alleging that
Valero intentionally and maliciously interfered with the plaintiffs' contracts
with Tejas. In its Sixth Amended Original Petition, plaintiffs are seeking
damages against Valero in an amount in excess of $36 million, and plaintiffs
added a conspiracy claim against Tejas alleging that Tejas conspired with Valero
in interfering with the contracts. Plaintiffs also have added a claim for
exemplary damages treble the amount of the actual damages, if any, found by the
court for the interference and conspiracy claims. Plaintiffs assert that Tejas
should be jointly liable with Valero for the damages plaintiffs have asserted
against Valero. Although Tejas has not obtained a formal opinion, based on
discussions with outside counsel and an internal examination of this lawsuit,
management believes that it has adequate defenses or recourse to third parties
relating to such lawsuit and does not believe this matter will have a material
adverse effect on Tejas' financial condition.

OTHER

      Tejas is also a party to various other claims and other pending and
possible legal actions arising in the ordinary course of business. There is
considerable uncertainty inherent in any litigation or governmental proceeding
and the evaluation of individual matters is necessarily dependent on the
historical experience of Tejas and others in similar circumstances and the stage
of the litigation or proceeding. Tejas believes that an adequate provision has
been made for probable losses. In cases where losses are possible but not
probable, it is Tejas' belief that their ultimate resolution will not have a
materially adverse effect on Tejas' consolidated financial position or the
results of its consolidated operations.

      Tejas has committed contractual obligations of approximately $50 million
for capital expenditures to be incurred in 1997.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

      In conjunction with the acquisition of the Acadian Gas Group on December
28, 1990, Acadian is committed to pay contingent deferred payments based upon
certain future natural gas sales volumes and profit margins, if achieved. Such
payments in any one year are not expected to exceed 2% of the cash purchase
price of the Acadian Gas Group and cumulative deferred payments are limited to a
maximum of $25 million, of which $5.3 million had been paid or accrued as of
December 31, 1996. Such payments expire if unearned not later than December 31,
2003. Tejas has guaranteed the performance of the deferred payment agreement. As
such payments are accrued, the cost is included in property, plant and equipment
and amortized over the remaining estimated lives thereof.

      Tejas' West Clear Lake Storage Facility ("WCLSF") requires the maintenance
of cushion gas in order to sustain anticipated operational requirements. Such
cushion gas requirements have been satisfied by a combination of natural gas
purchased by Tejas and third party natural gas stored in the facility. At
December 31, 1996, Tejas had purchased approximately 10.4 Bcf of cushion gas. In
late 1994, Tejas entered into an agreement with a third party whereby the third
party agreed to purchase up to 35 Bcf of natural gas at a cost not to exceed $65
million and to store such gas in the WCLSF. The agreement with the third party
was scheduled to expire in September 2000. Effective January 16, 1997, the third
party agreement described above was amended and extended. The principal
modifications to the agreement included the extension of the contract expiration
date to December 31, 2002 and, at Tejas' option, an increase in the maximum
volume of natural gas that may be stored in Tejas' facilities, including the
Greasy Creek Storage Facility, to 70 Bcf. In order to secure Tejas' ability to
purchase the natural gas from the third party, the agreement provides for the
payment by Tejas of a reservation fee to the third party which is adjusted
quarterly based upon the third party's financing costs. On certain option dates,
Tejas may elect to purchase specified volumes of the third party's gas based
upon market prices. Should Tejas decline to purchase the natural gas, the third
party may instruct Tejas to sell such volumes on the third party's behalf. In
such case, it will be necessary for Tejas to obtain cushion gas through other
means in order to meet the anticipated operational requirements of the WCLSF. At
December 31, 1996 and 1995, the third party had 18.5 Bcf of natural gas in
storage at the WCLSF, which such party purchased for $33.1 million. Based upon
the volumes and rates in effect Tejas paid a reservation fee of approximately
$1.1 million, $1.9 million and $1.6 million to the third party during 1996, 1995
and 1994, respectively.

    Tejas bears the cost of physical loss, if any, incurred during storage.
Management estimates that physical losses will not be significant and has
insured against physical losses due to catastrophic events.


14. LEASES

      Tejas leases certain property, facilities and equipment under various
operating leases. During 1993, Tejas entered into a five-year operating lease
("Leased System") with an unrelated third party and Tejas is committed to pay a
termination fee of $122.8 million in the event Tejas elects not to exercise its
purchase option for the Leased System in 1998. Lease payments under the lease
for the Leased System are adjusted quarterly based upon the Lessor's financing
costs, and Tejas has entered into interest rate derivative agreements in a
notional amount of $144.5 million to fully hedge the effects of such adjustments
on the required minimum lease payments. Such interest rate derivative agreements
expire in 1998 and effectively fix Tejas' minimum lease payments for the Leased
System, excluding the termination fee, at $8.7 million per anum.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

      Immediately prior to the Transok acquisition, CSW sold seven natural gas
processing plants (the "Transok Plants") to a third party lessor (the "Lessor"),
which in turn leased these facilities to Tejas. The Lessor is leasing the
Transok Plants to Tejas for a five-year term with lease payments adjusted
quarterly based upon the Lessor's financing costs. Tejas has entered into
interest rate derivative agreements in a notional amount of $125 million to
hedge the effects of such adjustments on the required minimum lease payments.
Under the Lease, the Lessee has the option to extend the term of the Lease for
up to two additional two year periods, subject to approval by the Lessor, and to
purchase all of the Transok Plants at any time for $125 million. If by the end
of the Lease term, the Lessee has not exercised its option to purchase all of
the Transok Plants, it is obligated to pay the Lessor a termination fee of
approximately $106 million. However, the Lease contains a provision which
reduces the termination fee to the extent the proceeds from the Lessor's
subsequent sale of the Transok Plants exceed $19 million. The Lease also
provides the Lessee the option to purchase, at any time during the Lease term,
one or more of the Transok Plants for an aggregate amount not exceeding $31
million, with corresponding reductions to the $106 million termination fee and
the $19 million threshold amount.

      During 1993, Transok entered into a long-term operating lease arrangement
to lease all the pipeline facilities of Palo Duro Pipeline Company. The
agreement, which includes provisions to purchase the leased pipeline assets,
provides for an initial term of five years with several options to extend the
lease for up to an additional seventeen years.

      Future minimum lease payments under all leases, excluding the termination
fees, as of December 31, 1996 are:

      In 1996, 1995 and 1994, stock options exercised were paid for in part by
the tendering of shares previously held by the party exercising the stock
options. The value of tendered shares received and an equivalent value for
shares issued are regarded as non-cash transactions for cash flow purposes.
Accordingly, Tejas' Consolidated Statements of Cash Flows include only actual
cash received as a result of the exercise of stock options.


16. SEGMENT INFORMATION AND MAJOR CUSTOMERS

      Tejas predominantly operates in one industry segment, natural gas pipeline
operations.

      Sales to Coral accounted for approximately 38% and 10% of Tejas' total
revenues during 1996 and 1995, respectively. No single customer accounted for
10% or more of total revenues in 1994.

      Tejas' natural gas pipeline operations have a concentration of customers
in the electric and natural gas utility industries, principally in Oklahoma,
Texas and Louisiana. This concentration of customers in a regional geographic
area may impact Tejas' overall exposure to credit risk, either positively or
negatively, in that the customers may be similarly affected by changes in
economic or other conditions. Historically, Tejas has not incurred any
significant credit losses related to receivables from its customers. Receivables
are generally not collateralized.

17. EMPLOYEE BENEFITS

      Effective January 1, 1989, Tejas adopted a noncontributory, defined
benefit pension plan. This plan covers all employees.

      Under the plan, pension benefits are based on years of service and the
employee's average monthly compensation. Tejas funds pension expense as accrued,
subject to the minimum requirements of the Employee Retirement Income Security
Act of 1974, the Omnibus Budget Reconciliation Act of 1987 and the tax
deductibility of such contributions.

      The components of pension expense are as follows:

June 6, 1996, Tejas entered into a promissory note payable to Transok, Inc. in
an original principal amount of $10 million. Prior to year-end, the principal
amount of this note was increased to $100 million. At December 31, 1996, the
balance under this promissory note including accrued interest was approximately
$43 thousand.

3.  MONEY MARKET CREDIT LINES

    Tejas has uncommitted money market credit lines which allow Tejas to borrow
up to $50 million for periods of up to two months. Any such borrowings are
unsecured and may be extended for additional periods if agreed to by the
lenders. At December 31, 1996, Tejas had no outstanding borrowings under the
money market credit lines. Tejas has agreed to maintain funds, including, but
not limited to, availability under the Credit Agreements and the Amended Transok
Credit Facility, sufficient to repay borrowings under the money market credit
lines and accordingly, any outstanding balances are classified as long-term
debt.

4.  GUARANTEES

      Tejas has guaranteed the performance of Acadian Gas Corporation under a
deferred payment agreement related to the acquisition of the Acadian Gas Group.
Tejas has also guaranteed the performance of Tejas Natural Gas Company ("TNGC")
under certain provisions of a five-year operating lease of a pipeline system and
has guaranteed the performance of TNGC and its subsidiaries' obligations under
certain purchase and transportation agreements.

<PAGE>
Participation Agreement is $125,000,000 (the "Prior Indebtedness") as shown on
SCHEDULE 2.2 hereto, and Lessee represents for itself and each Participant
represents and warrants for itself, that its outstanding Funded Amounts, if any,
under the Participation Agreement as of the Amendment Effective Date are as set
forth in the second column of SCHEDULE 2.2 hereto. Participants hereby sell,
assign, transfer and convey, and Participants (including, without limitation,
those Participants not previously a party to the Participation Agreement) hereby
purchase and accept so much of the Prior Indebtedness and all of the rights,
titles, benefits, interests, privileges, claims, liens, security interests, and
obligations existing and to exist (collectively the "INTERESTS") such that each
Participants' Commitment Percentage of the outstanding Funded Amounts and
Commitments under the Participation Agreement as amended and restated by this
Agreement shall be as set forth in SCHEDULE 2.2 hereto as of the Amendment
Effective Date. The foregoing assignment, transfer and conveyance are without
recourse to the Participants and without any warranties whatsoever as to title,
enforceability, collectibility, documentation or freedom from liens or
encumbrances, in whole or in part, other than the warranty by each Participant
that it has not sold, transferred, conveyed or encumbered such Interests. If as
a result thereof, a Participant's Commitment Percentage of the outstanding
Funded Amounts under the Participation Agreement as amended by this Amendment is
less than its outstanding Funded Amounts under the Participation Agreement on
the Amendment Effective Date, the difference set forth in the last column of
SCHEDULE 2.2 hereto shall be remitted to such Participant by the Administrative
Agent upon receipt of funds from the other Participants shown in the last column
of SCHEDULE 2.2 on the Amendment Effective Date. Each Participant so acquiring a
part of such outstanding loans and letter of credit reimbursement obligations
assumes its Commitment Percentage of the outstanding Funded Amounts,
Commitments, rights, titles, interests, privileges, claims, liens, security
interests, benefits and obligations under the Operative Documents. Participants
are proportionately released from the obligations assumed by Participants so
acquiring such obligations and, to that extent, the Participants so released
shall have no further obligation under the Participation Agreement, as amended
and restated hereby. The Borrower hereby represents and warrants that it has no
defenses, offsets or counterclaims to the Prior Indebtedness or its obligations
or rights under the Participation Agreement or the Operative Documents,
including, without limitation, the Interests being assigned pursuant to this
SECTION F. Each Participant confirms that it has received a copy of the Bank/CSW
Agreement and represents, warrants and agrees that it has acquired its Interests
subject in all respects to the terms and provisions of the Bank/CSW Agreement.
Any Funded Amounts outstanding under the Participation Agreement on the
Amendment Effective Date bearing interest at a Eurodollar Interest Rate shall be
deemed continued as a Funded Amount under this Amendment at such Eurodollar
Interest Rate and for the Interest Period with respect thereto under the
Participation Agreement.

        G.     MISCELLANEOUS PROVISIONS.

               1. COUNTERPARTS. This Amendment may be executed in any
number of counterparts, each of which shall be deemed an original of this
Amendment and all of which will constitute but one and the same agreement.

      SECTION 2.1 COMMITMENTS.  Subject to the terms and conditions of this
Agreement, each Lender severally and for itself alone agrees to make extensions
of credit pursuant to the Commitments as described in this ARTICLE II.

      SECTION 2.1.1 LOAN COMMITMENT. From time to time on any Business Day
occurring prior to the Commitment Termination Date each Lender will make loans
(relative to such Lender, its "LOANS") to the Borrower equal to such Lender's
Percentage of the aggregate amount of Loans requested by the Borrower to be made
on such day. No Lender shall be permitted or required to make any Loan if, after
giving effect thereto, the aggregate outstanding principal amount of all Loans
(i) of all Lenders would exceed the Loan Commitment Amount or (ii) of such
Lender would exceed such Lender's Percentage of the Loan Commitment Amount or
such Lender's Designated Maximum Commitment. On the terms and subject to the
conditions hereof, the Borrower may from time to time borrow, prepay, repay and
reborrow Loans.

      SECTION 2.1.2 LETTER OF CREDIT COMMITMENT. From time to time on any
Business Day occurring at least six (6) Business Days prior to the Commitment
Termination Date then in effect, the Issuing Bank will issue, and each Lender
will participate in, standby letters of credit (herein individually referred to
as a "LETTER OF CREDIT" and collectively referred to as "LETTERS OF CREDIT") for
the account of the Borrower, and in the name of the Borrower or any Subsidiary
of the Borrower, in a principal amount equal to such Lender's Percentage of the
face amount of all Letters of Credit requested by the Borrower to be issued on
such day. Neither the Issuing Bank nor any Lender shall be permitted or required
to issue or participate in any Letter of Credit if, after giving effect thereto,
(i) the aggregate of all Letter of Credit Liabilities outstanding on such date
under and in connection with all Letters of Credit of all Lenders would 

                                      24
<PAGE>
exceed the Letter of Credit Commitment Amount or (ii) the Percentage of such
Lender in all Letter of Credit Liabilities outstanding on such date would exceed
such Lender's Percentage of the Letter of Credit Commitment Amount. Anything
herein contained to the contrary notwithstanding, BMO's obligations and
commitments to issue Letters of Credit hereunder shall cease immediately and
automatically and without further action of any kind if BMO ceases to be the
Administrative Agent hereunder. On the terms and subject to the conditions
hereof, the Borrower may from time to time request, reimburse and request new
Letters of Credit.

      SECTION 2.1.3 LENDERS NOT PERMITTED OR REQUIRED TO MAKE BORROWINGS
AVAILABLE. No Lender shall be permitted or required to make any Loan or
participate in (and the Issuing Bank shall have no obligation to issue) any
Letter of Credit, if, after giving effect thereto and to all other Borrowings
and conversions and continuations to be made on such date, (a) the Aggregate
Revolving Outstandings of all Lenders would exceed the Commitment Amount or (b)
the sum of the aggregate outstanding principal amount of all Loans of such
Lender PLUS the aggregate of such Lender's Percentage of all Letter of Credit
Liabilities would exceed the lesser of (i) such Lender's Percentage of the
Commitment Amount and (ii) such Lender's Designated Maximum Commitment.

      SECTION 2.2 DOMESTIC LOANS AND EURODOLLAR LOANS. Subject to the terms and
conditions set forth in ARTICLE VI, each Loan shall be either a Eurodollar Loan
or a Domestic Loan as the Borrower may request, it being understood that Loans
made to the Borrower on any date may be either Eurodollar Loans or Domestic
Loans or a combination thereof. As to any Eurodollar Loan, each Lender may, if
it so elects, fulfill its commitment to make such Eurodollar Loan by causing a
Lending Installation to make such Eurodollar Loan; PROVIDED, HOWEVER, that in
such event the obligation of the Borrower to repay such Eurodollar Loan
nevertheless shall be to such Lender and shall be deemed to be held by such
Lender for the account of such Lending Installation.

      SECTION 2.3 BORROWING PROCEDURES. The Borrower shall give the
Administrative Agent prior written or telegraphic notice (in substantially the
form of EXHIBIT 2.3 hereto) of each proposed Borrowing or continuation, and as
to whether such Borrowing or continuation is to be of Domestic Loans, Eurodollar
Loans or Letters of Credit, as follows:

      SECTION 2.3.1 DOMESTIC LOANS. The Administrative Agent shall receive
written or telegraphic notice from the Borrower on or before 11:00 a.m. Chicago
time at least one (1) Domestic Business Day prior to the date requested for each
proposed Borrowing of a Domestic Loan of the date of such Borrowing and amount
of such Borrowing (which shall be in a minimum amount of $1,000,000 or in the
unused amount of the Loan Commitment), and the Administrative Agent shall advise
each Lender thereof promptly thereafter. Not later than 10:00 a.m., Chicago
time, on the date specified in such notice for such Borrowing, each Lender shall
provide to the Administrative Agent at the Payment Office, same day or
immediately available funds covering such Lender's Percentage of the requested
Domestic Loan. Upon fulfillment of the applicable conditions set forth in
ARTICLE XI with respect to such Domestic Loan, the Administrative Agent shall
make available to the Borrower the proceeds of each 

                                      25
<PAGE>
Domestic Loan (to the extent received from the Lenders) by wire transfer of such
proceeds to such account(s) as the Borrower shall have specified in the
Borrowing Request.

      SECTION 2.3.2  EURODOLLAR LOANS. The Administrative Agent shall receive
written or telegraphic notice from the Borrower on or before 11:00 a.m. Chicago
time, (i) at least three (3) Eurodollar Business Days prior to the date
requested for each proposed Borrowing or continuation of a Eurodollar Loan
having an initial one (1), two (2), three (3) or six (6) month Eurodollar
Interest Period and (ii) at least four (4) Eurodollar Business Days prior to the
date requested for each proposed Borrowing or continuation of a Eurodollar Loan
having an initial twelve (12) month Eurodollar Interest Period, of the date of
such Borrowing or continuation, as the case may be, the amount of such Borrowing
or continuation, as the case may be (which shall be in a minimum amount of
$5,000,000 or in the unused amount of the applicable Commitment), and the
duration of the initial Eurodollar Interest Period with respect thereto, and the
Administrative Agent shall advise each Lender thereof promptly thereafter. Not
later than 10:00 a.m., Chicago time, on the date specified in such notice for
such Borrowing, each Lender shall provide to the Administrative Agent at the
Payment Office, same day or immediately available funds covering such Lender's
Percentage of the requested Eurodollar Loan. Upon fulfillment of the applicable
conditions set forth in ARTICLE XI with respect to such Eurodollar Loan, the
Administrative Agent shall make available to the Borrower the proceeds of each
Eurodollar Loan (to the extent received from the Lenders) by wire transfer of
such proceeds to such account(s) as the Borrower shall have specified in the
Borrowing Request.

      SECTION 2.3.3 LETTERS OF CREDIT. The Administrative Agent shall receive
written or telegraphic notice from the Borrower on or before 11:00 a.m. Chicago
time at least three (3) Domestic Business Days prior to the proposed issuance
date of a Letter of Credit, and the Administrative Agent shall advise the
Issuing Bank and each Lender thereof promptly thereafter. Each Borrowing Request
for the issuance of a Letter of Credit shall be accompanied by an Issuance
Request, substantially in the form of EXHIBIT 2.3.3A, with appropriate
insertions, setting forth in detail the proposed terms of such requested Letter
of Credit, including, without limitation, the proposed date of issuance, amount,
beneficiary, expiry date and documents to be required upon presentation, if any
(such terms regarding documents required upon presentation to be satisfactory in
form and substance to the Issuing Bank). Each Letter of Credit shall have a
fixed expiration date occurring not later than one (1) year after the date of
issuance thereof (and in no event later than five (5) Business Days prior to the
earlier of (a) the Commitment Termination Date in effect at the time of issuance
thereof and (b) the next scheduled Election Effective Date, if any, in effect at
the time of issuance thereof), may, by its terms, be renewable annually for
additional one-year periods (but in no event later than five (5) Business Days
prior to the earlier of (a) the Commitment Termination Date in effect at the
time of renewal thereof and (b) the next scheduled Election Effective Date, if
any, in effect at the time of renewal thereof) unless notice of non-renewal is
received by the beneficiary thereof in accordance with the terms of such Letter
of Credit, and shall provide that demands for payment thereunder be made at
least three (3) Domestic Business Days prior to the proposed date of payment;
PROVIDED, HOWEVER, that for all purposes of this Agreement (other than the
condition requiring delivery of a Borrowing Request and an Issuance Request and
except that customary renewal fees, rather than issuance fees, of the Issuing
Bank shall be payable with respect to such renewals) 

                                      26
<PAGE>
the renewal of a Letter of Credit shall be considered an issuance thereof and
the Borrower shall be required to comply with all the provisions of this
Agreement with respect to any such renewal to the same extent as if a new Letter
of Credit was being issued on such renewal date. Upon fulfillment of the
applicable conditions set forth in ARTICLE XI and subject to the terms hereof,
the Issuing Bank shall issue such Letter of Credit to the requested beneficiary
no later than the close of business on the date of such proposed issuance. Each
Lender shall, upon the issuance of each Letter of Credit and without further
action, hold a participation therein and each Lender hereby irrevocably and
unconditionally purchases a participation in each such Letter of Credit in an
amount equal to such Lender's Percentage of the face amount of such Letter of
Credit. Each Lender shall, to the extent of its Percentage, be responsible for
reimbursing promptly (and in any event within one Business Day), without setoff,
deduction or counterclaim, the Issuing Bank for Reimbursement Obligations which
have not been reimbursed by the Borrower in accordance with SECTION 2.4.2.

      SECTION 2.4 LETTER OF CREDIT PROCEDURES.

      SECTION 2.4.1 LETTER OF CREDIT OPERATIONS. The Issuing Bank shall,
promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment by a beneficiary under a Letter of Credit to
ascertain that the same appear on their face to be in conformity with the terms
and conditions of such Letter of Credit. If, after examination, the Issuing Bank
shall have determined that a demand for payment under such Letter of Credit does
not conform to the terms and conditions of such Letter of Credit, then the
Issuing Bank shall, as soon as reasonably practicable, give notice to such
beneficiary to the effect that such demand for payment was not in accordance
with the terms and conditions of such Letter of Credit, stating the reasons
therefor. Thereupon, such beneficiary may attempt to correct any such
non-conforming demand for payment under such Letter of Credit if, and to the
extent that, such beneficiary is entitled (without regard to the provisions of
this sentence) and able to do so. The Lenders hereby expressly agree to accept
as correct and conclusive, in the absence of gross negligence or willful
misconduct, any determination by the Issuing Bank that any demand for payment
under a Letter of Credit complies, or does not comply, with the terms and
conditions of such Letter of Credit.

      After determining that a demand for payment under such Letter of Credit
conforms to the terms and conditions thereof, the Issuing Bank shall promptly
notify the Lenders by telecopy of the same.

      SECTION 2.4.2 BORROWER'S AGREEMENT TO REPAY LETTER OF CREDIT DRAWINGS. The
Borrower hereby agrees to reimburse the Issuing Bank, forthwith, for each
payment or disbursement made by the Issuing Bank to settle its obligations under
any draft drawn under any Letter of Credit, with interest on the amount so paid
or disbursed by the Issuing Bank from and including the date of payment or
disbursement to, but not including, the date the Issuing Bank is reimbursed
therefor or the Lenders are deemed to have made a Loan in respect thereof
pursuant to the following proviso, as the case may be, at the rate set forth in
SECTION 4.1.1(A) (any and all obligations of the Borrower to reimburse the
Issuing Bank hereunder with respect to each payment or disbursement made by the
Issuing Bank under a Letter of Credit being herein 

                                      27
<PAGE>
referred to as a "REIMBURSEMENT OBLIGATION" and collectively as "REIMBURSEMENT
OBLIGATIONS"); PROVIDED, HOWEVER, that if any such payment or disbursement shall
not be reimbursed to the Issuing Bank after any grace period for the payment
thereof as provided in SECTION 12.1.1 herein and if the Commitment Termination
Date shall not have occurred, then the Reimbursement Obligation in respect
thereof shall automatically, without notice from or to the Borrower and without
any further authorization from the Borrower (and whether or not the amount
thereof satisfies the conditions of SECTION 2.3.1 and whether or not the
conditions of ARTICLE XI are satisfied), be deemed to be a Loan, made by each of
the Lenders to the Borrower in their respective Percentages of the Issuing
Bank's payments or disbursements bearing interest determined pursuant to SECTION
4.1.1(A) and the related Letter of Credit Liability shall be deemed paid
simultaneously with such funding of the deemed Loan; PROVIDED FURTHER, HOWEVER,
that if any such payment or disbursement shall not be reimbursed to the Issuing
Bank and a Loan shall not be deemed to have been made notwithstanding the
preceding proviso due to failure to meet the applicable conditions in ARTICLE
XI, then the Reimbursement Obligation in respect thereof shall be due and
payable, with interest accruing thereon at the rate set forth in SECTION
4.1.2(C), if applicable.

      Any action taken by the Issuing Bank, any Lender, the Administrative
Agent, the Documentation Agent or the Collateral Agent in connection with any
Letter of Credit or any draft thereon or demand for payment thereunder shall, if
in good faith and in conformity with all laws, regulations or customs applicable
thereto, be binding upon the Borrower and its Subsidiaries and shall not place
the Issuing Bank, any Lender, the Administrative Agent, the Collateral Agent or
the Documentation Agent under any resulting liability to the Borrower or any of
its Subsidiaries. Without limiting the generality of the foregoing, the Borrower
and its Subsidiaries assume all risks of the acts or omissions of any
beneficiary or transferee of each Letter of Credit and neither the Issuing Bank,
the Lenders, the Administrative Agent, the Collateral Agent nor the
Documentation Agent nor any of their respective officers, directors or agents
shall be liable or responsible for (i) the use which may be made of any Letters
of Credit or any acts or omissions of any beneficiary or transferee in
connection therewith, (ii) the validity or genuineness of any document specified
in, or demand for payment under, any Letter of Credit, or any endorsements
thereon, even if such document or demand should prove to be in any or all
respects invalid, fraudulent or forged (and the Issuing Bank may accept
documents and demands that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary), (iii) failure of any draft to bear any reference
or adequate reference to a Letter of Credit, or failure of any Person to note
the amount of any draft on the reverse side of a Letter of Credit, (iv) errors,
omissions, interruptions or delays in transmission or delivery of any message by
mail, cable, telegram, telecopier, wireless or otherwise, (v) errors in
translation or errors in interpretation of technical terms or (vi) any error,
neglect, default, suspension or insolvency of any of the Issuing Bank's
correspondents. Notwithstanding the foregoing, the Borrower shall not be
obligated to reimburse the Issuing Bank for any wrongful payment or disbursement
made by the Issuing Bank under any Letter of Credit as a result of acts or
omissions constituting gross negligence or willful misconduct on the part of the
Issuing Bank or any of its officers, directors, employees or agents.

                                      28
<PAGE>
      THE BORROWER WILL ON DEMAND INDEMNIFY AND KEEP THE ISSUING BANK AND EACH
LENDER HARMLESS FROM AND AGAINST ALL LIABILITIES, LOSSES, DAMAGES, CLAIMS,
COSTS, DEMANDS AND ACTIONS WHICH THE ISSUING BANK OR SUCH LENDER MAY SUFFER OR
INCUR IN CONNECTION WITH ANY LETTER OF CREDIT OR ANY PAYMENT THEREUNDER, EXCEPT
TO THE EXTENT DUE TO THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE ISSUING
BANK OR SUCH LENDER OR RESULTING FROM THE ISSUING BANK'S OR SUCH LENDER'S OWN
UNEXCUSED BREACH OF ANY MATERIAL PROVISION OF ANY LOAN DOCUMENT, PROVIDED THAT
IT IS THE INTENTION OF THE PARTIES HERETO FOR THE ISSUING BANK AND EACH LENDER
TO BE INDEMNIFIED IN THE CASE OF SIMPLE NEGLIGENCE, INCLUDING THEIR OWN
NEGLIGENCE. The obligations of the Borrower under this SECTION 2.4.2 shall not
be impaired by (i) any waiver or time granted to or by the Issuing Bank, any
Lender, the Documentation Agent, the Administrative Agent or the Collateral
Agent, (ii) any release or dealings with any rights or security of the Issuing
Bank, any Lender, the Documentation Agent, the Administrative Agent or the
Collateral Agent (including, without limitation, under any of the Security
Documents or any of the Guaranties), (iii) any invalidity of any Letter of
Credit or (iv) any other circumstances (other than an express release in writing
by the relevant beneficiaries) which might impair such obligations. Anything in
this SECTION 2.4.2 to the contrary notwithstanding, the Borrower does not hereby
waive its right to pursue an action against the Issuing Bank or any Lender for
willful misconduct or gross negligence by the Issuing Bank, such Lender or any
of their officers, employees or agents in connection with a Letter of Credit or
any payment thereunder.

      SECTION 2.4.3 LENDERS' AGREEMENT TO REPAY LETTER OF CREDIT DRAWINGS. Any
action taken by the Issuing Bank, any Lender, the Administrative Agent, the
Documentation Agent or the Collateral Agent in connection with any Letter of
Credit or any draft thereon or demand for payment thereunder shall, if in good
faith and in conformity with all laws, regulations or customs applicable
thereto, be binding upon the Lenders and shall not place the Issuing Bank, any
Lender, the Administrative Agent, the Collateral Agent or the Documentation
Agent under any resulting liability to any of the other Lenders. Without
limiting the generality of the foregoing, the Lenders assume all risks of the
acts or omissions of each beneficiary or transferee of each Letter of Credit and
neither the Issuing Bank nor any of its officers, directors, employees, or
agents shall be liable or responsible for (i) the use which may be made of any
Letters of Credit or any acts or omissions of any beneficiary or transferee in
connection therewith, (ii) the validity or genuineness of any document specified
in, or demand for payment under, any Letter of Credit, or any endorsements
thereon, even if such document or demand should prove to be in any or all
respects invalid, fraudulent or forged (and the Issuing Bank may accept
documents and demands that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary), (iii) failure of any draft to bear any reference
or adequate reference to a Letter of Credit, or failure of any Person to note
the amount of any draft on the reverse side of a Letter of Credit, (iv) errors,
omissions, interruptions or delays in transmission or delivery of any message by
mail, cable, telegram, telecopier, wireless or otherwise, (v) errors in
translation or errors in interpretation of technical terms or (vi) any error,
neglect, default, suspension or insolvency of any of the Issuing Bank's
correspondents. Notwithstanding the foregoing, no Lender shall be obligated to
reimburse the Issuing Bank for any wrongful payment or disbursement made by the
Issuing Bank 

                                      29
<PAGE>
under any Letter of Credit as a result of acts or omissions constituting gross
negligence or willful misconduct on the part of the Issuing Bank or any of its
officers, employees or agents.

      SECTION 2.4.4 PROCEDURES FOR DEPOSITING CASH COLLATERAL. Any cash
collateral amounts received by the Collateral Agent pursuant to SECTION 5.7 or
12.3 shall be retained by the Collateral Agent for the benefit of the Lenders as
collateral security for, and the Borrower hereby grants to the Collateral Agent
a security interest in, such cash collateral, the Permitted Cash Collateral
Investments and the proceeds of any thereof to secure, first, the payment of the
Obligations of the Borrower under and in connection with the Letters of Credit
and then the other Obligations of the Borrower under and in connection with this
Agreement and the other Loan Documents. If, and to the extent that (i) all
Obligations of the Borrower in connection with all outstanding Letters of Credit
and all other Obligations have been fully paid and satisfied, and (ii) the
Commitments have terminated, the Collateral Agent shall pay to the Borrower,
upon the Borrower's request therefor, all amounts previously paid by the
Borrower pursuant to SECTION 5.7 or 12.3, plus any interest earned thereon, and
not theretofore applied by the Collateral Agent to reduce amounts payable by the
Borrower to the Issuing Bank and the Lenders under or in connection with the
Letters of Credit or other Obligations. All amounts on deposit pursuant to this
SECTION 2.4.4 shall, until their application to any Obligation or their return
to the Borrower, as the case may be, at the Borrower's written request, be
invested in Permitted Cash Collateral Investments designated by the Borrower,
which Permitted Cash Collateral Investments shall be held by the Collateral
Agent as additional collateral security for the repayment of the Borrower's
Obligations under and in connection with the Letters of Credit and all other
Obligations. Any losses, net of earnings, and reasonable fees and expenses of
such Permitted Cash Collateral Investments shall be charged against the
principal amount invested. The Collateral Agent and the Lenders shall not be
liable for any loss resulting from any Permitted Cash Collateral Investment made
by it at the Borrower's request. The Collateral Agent is not obligated hereby,
or by any other Loan Document, to make or maintain any Permitted Cash Collateral
Investment, except upon written request by the Borrower.

      SECTION 2.5 [INTENTIONALLY OMITTED]

      SECTION 2.6 INCREASED CAPITAL COSTS. If any Regulatory Change imposes,
modifies, or deems applicable any capital adequacy, capital maintenance, or
similar requirement (including a request or requirement which affects the manner
in which any Lender or the Issuing Bank allocates capital resources to its
commitments, including its Commitments hereunder) and as a result thereof, in
the opinion of such Lender or the Issuing Bank, the rate of return on such
Lender's or the Issuing Bank's capital as a consequence of its Commitments, the
Loans made by such Lender or its issuance of or participation in the Letters of
Credit is reduced to a level below that which such Lender or the Issuing Bank
could have achieved but for such circumstances, then and in each such case upon
notice from time to time by such Lender or the Issuing Bank to the Borrower, the
Borrower shall pay (without duplication of costs paid pursuant to SECTIONS 4.9
and 4.12) to such Lender or the Issuing Bank such additional amount or amounts
as shall compensate such Lender or the Issuing Bank for such reduction in rate
of return. Each Lender and the Issuing Bank, upon determining in good faith that
any additional amounts are 

                                      30
<PAGE>
payable pursuant to this SECTION 2.6, will give prompt written notice thereof to
the Borrower with a copy to the Administrative Agent, PROVIDED that the failure
to give any such notice shall not release or diminish the Borrower's obligations
to pay additional amounts pursuant to this SECTION 2.6; PROVIDED FURTHER,
HOWEVER, that the Borrower shall not be obligated to pay additional amounts
attributable to such reduction under this SECTION 2.6 in respect of time periods
more than 180 days prior to the date of such notice. A statement of any Lender
or the Issuing Bank as to any such additional amount or amounts (including
calculations thereof in reasonable detail) shall be rebuttable presumptive
evidence of such cost and amount. In determining such amount, any Lender and the
Issuing Bank may use any method of averaging and attribution that it (in its
sole and absolute discretion) shall deem applicable.

      SECTION 2.7 EXTENSION OF SCHEDULED COMMITMENT TERMINATION DATE, INITIAL
COMMITMENT AMORTIZATION DATE AND REVOLVING COMMITMENTS.

            (a)   Subject to the other provisions of this Agreement, the
                  Commitments of the Lenders shall be effective for an initial
                  period from the Effective Date to the original Scheduled
                  Commitment Termination Date; PROVIDED that the Revolving
                  Commitments of the Lenders, and concomitantly the Initial
                  Commitment Amortization Date and the Scheduled Commitment
                  Termination Date, may be extended for successive one-year
                  periods expiring, in the case of the Revolving Commitments and
                  the Scheduled Commitment Termination Date, on the date which
                  is one year from the then Scheduled Commitment Termination
                  Date, and in the case of the Initial Commitment Amortization
                  Date, on the date which is one year from the then scheduled
                  Initial Commitment Amortization Date, in accordance with the
                  terms of this SECTION 2.7. If the Borrower shall request in an
                  Annual Certificate of Extension delivered to the
                  Administrative Agent not more than one hundred twenty (120)
                  nor less than sixty (60) days prior to an Anniversary Date,
                  that the Revolving Commitments of the Lenders be extended for
                  one year from the then Scheduled Commitment Termination Date
                  and that the Initial Commitment Amortization Date be extended
                  for one year from the then scheduled Initial Commitment
                  Amortization Date, then the Administrative Agent shall
                  promptly notify each Lender of such request and each Lender
                  shall notify the Administrative Agent, not fewer than thirty
                  (30) days prior to such Anniversary Date, whether, in the
                  exercise of its sole discretion, it will extend the Scheduled
                  Commitment Termination Date and the Initial Commitment
                  Amortization Date and, in the event such Lender is a Reduced
                  Declining Lender such notice will specify a proposed Total
                  Committed Amount and its proposed Designated Maximum
                  Commitment. Any Lender which shall not timely notify the
                  Administrative Agent whether it will extend the Scheduled
                  Commitment Termination Date and the Initial Commitment
                  Amortization Date shall be deemed to not have agreed to extend
                  the Scheduled Commitment Termination Date and the 

                                      31
<PAGE>
                  Initial Commitment Amortization Date. No Lender shall have any
                  obligation whatsoever to extend the Scheduled Commitment
                  Termination Date or the Initial Commitment Amortization Date.
                  Any agreement to extend the Scheduled Commitment Termination
                  Date and the Initial Commitment Amortization Date shall be
                  irrevocable, except as provided in SECTION 2.7(C).

            (b)   If all the Lenders notify the Administrative Agent pursuant to
                  CLAUSE (A) of this SECTION 2.7 of their agreement to extend
                  the Scheduled Commitment Termination Date and the Initial
                  Commitment Amortization Date (each Lender agreeing to extend
                  the Scheduled Commitment Termination Date and the Initial
                  Commitment Amortization Date herein called an "ACCEPTING
                  LENDER"), then the Administrative Agent shall so notify each
                  Lender and the Borrower, and such extension shall be effective
                  without other or further action by any party hereto for such
                  additional one-year period.

            (c)   If any one or more of the Lenders shall notify or be deemed to
                  have notified the Administrative Agent pursuant to CLAUSE (A)
                  of this SECTION 2.7 that it will not extend the then Scheduled
                  Commitment Termination Date and the then scheduled Initial
                  Commitment Amortization Date at the then current Total

                                  ARTICLE III

                PROVISIONS RELATING TO THE NOTES AND REPAYMENT

      SECTION 3.1 THE NOTES. Each Lender's Loans under the Revolving Commitment
shall be evidenced by a Note of the Borrower substantially in the form set forth
in EXHIBIT 3.1 (such Note herein called the "NOTE") with appropriate insertions,
and dated the Initial Borrowing Date (or such other date prior thereto as shall
be satisfactory to the Co-Agents), payable to the order of such Lender in a
maximum principal amount equal to such Lender's Percentage of the Original Total
Committed Amount. The date and amount of each Loan made by such Lender and of
each repayment of principal thereon received by such Lender shall be recorded by
such Lender in its records or, at its option, on the schedule attached to the
Note issued to such Lender. The aggregate unpaid principal amount so recorded
shall be rebuttable presumptive evidence of the principal amount owing and
unpaid on such Note. The failure to so record any such amount or any error in so
recording any such amount shall not, however, limit or otherwise affect the
obligations of the Borrower hereunder or under any Note to repay the principal
amount of the Loans together with all interest accruing thereon.

      SECTION 3.2 REPAYMENTS. The Borrower shall repay in full the unpaid
principal amount of each Loan upon the Stated Maturity Date.

      SECTION 3.3 DUE DATE EXTENSION. If any payment of principal of, or
interest on, any Eurodollar Loan shall fall due on a day which is not a
Eurodollar Business Day, or if any pay ment of principal of or interest on any
Domestic Loan or any payment of any fee provided for herein or any other amount
due hereunder shall fall due on a day which is not a Domestic Business Day, then
such due date shall be extended to the next succeeding Eurodollar Business Day
or Domestic Business Day, as the case may be (unless, with respect to a payment
relating to a Eurodollar Loan, such due date would fall in another calendar
month, in which event payment shall be made on the next preceding Eurodollar
Business Day) and additional interest and fees shall accrue and be payable for
the period of such extension.

                                  ARTICLE IV

                          INTEREST, FEES AND SPECIAL

outstanding on the Loans and any unpaid Reimbursement Obligations with respect
to the Letters of Credit shall bear interest at a fluctuating rate per annum
equal to:

                  time to time in effect, PLUS the Applicable Margin for Loans

                  from time to time in effect.

      SECTION 4.1.2 INTEREST AFTER MATURITY. After the date any principal amount
of any Loan is due and payable (whether on the Stated Maturity Date, upon
acceleration or otherwise) and after any other monetary Obligation with respect
to Letters of Credit of the Borrower hereunder shall have become due and
payable, and after any applicable grace periods have lapsed, until paid, such
due and payable amounts and Obligations shall bear interest, but only to the
extent permitted by applicable law, at a fluctuating rate per annum equal to:

                  Interest Period of one (1) day, one (1) week, or one (1) month
                  (as the Administrative Agent shall select in the exercise of
                  its sole discretion) determined as at 9:00 a.m., Chicago time,
                  on the Eurodollar Business Day next succeeding that on which
                  the Administrative Agent became aware of such default, all of
                  the foregoing as determined by the Administrative Agent;
                  PROVIDED that so long as the principal amount or any part
                  thereof of any such Eurodollar Loan remains unpaid, the rate
                  herein provided for shall be recalculated on the same basis as
                  aforesaid on the last day of each period for which such rate
                  has been determined as aforesaid. If on any occasion any of
                  the Reference Lenders is unable, or for any reason fails, so
                  to notify the Administrative Agent by 10:00 a.m., Chicago time

                  determined on the basis of the quotations furnished by the
                  other Reference Lenders to the Administrative Agent at or
                  prior to said 10:00 a.m.; and

            (c)   as to any other unpaid monetary Obligations with respect to
                  Letters of Credit, the sum of the Applicable Default Margin,
                  PLUS the Applicable Margin for Loans with respect to Domestic
                  Loans from time to time in effect, PLUS the Alternate Base
                  Rate from time to time in effect.

      SECTION 4.2 NOTICE OF EURODOLLAR INTEREST RATE; DETERMINATION CONCLUSIVE.
The Eurodollar Interest Rate with respect to each Eurodollar Interest Period
shall be determined by the Administrative Agent as provided in the definition of
Eurodollar Interest Rate in SECTION 1.1, and notice thereof shall be given
promptly by the Administrative Agent to the Borrower and the Lenders. Each
determination of the Eurodollar Interest Rate by the Administrative Agent shall
be conclusive and binding upon the parties hereto, in the absence of
demonstrable error. At the request in writing of the Borrower, however, the
Administrative Agent shall deliver to the Borrower a statement showing in
reasonable detail the computations used by the Administrative Agent in
determining the Eurodollar Interest Rate.

      SECTION 4.3 EURODOLLAR INTEREST PERIODS.  Subject to the provisions of
SECTION 4.1.2(B) and subject to the requirements of the definition of Eurodollar
Interest Period, the Borrower may elect to continue a Eurodollar Loan from one
Eurodollar Interest Period into the subsequent Eurodollar Interest Period, in
the notice required by SECTION 2.3.2 above. If no such election is made and such
Eurodollar Loan is not repaid, the Borrower shall be deemed to have elected a
one (1) month Eurodollar Interest Period.

      SECTION 4.4 COMMITMENT FEE; OTHER FEES.

            (a)   The Borrower agrees to pay to the Administrative Agent for the
                  account of each Lender, for the period commencing on the
                  Effective Date, and continuing through the Commitment
                  Termination Date, a commitment fee at a rate PER ANNUM equal
                  to the Commitment Fee Rate on such Lender's Percentage of the
                  sum of the average daily unused portion of the Commitment
                  Amount (it being understood that, with respect to any Lender,
                  the principal amount of its Loans and the outstanding
                  principal amount of its Percentage of Letter of Credit
                  Liabilities shall be considered utilizations of the Commitment
                  Amount). Such commitment fees shall be payable by the Borrower
                  in arrears on the last Business Day of March, June, September
                  and December of each year, the first such payment to be made
                  on December 31, 1996 for the period then ending for which no
                  fees shall theretofore have been paid, and on the Commitment
                  Termination Date.

                                      40
<PAGE>
            (b)   The Borrower agrees to pay to the Administrative Agent for the
                  account of each Lender a restructuring fee pursuant to that
                  certain fee letter agreement dated the date hereof between the
                  Borrower and the Administrative Agent.

      SECTION 4.5 LETTER OF CREDIT FEES. (a) The Borrower agrees to pay to the
Administrative Agent for the account of each Lender with respect to each Letter
of Credit issued hereunder, for the period from and including the date of
issuance of such Letter of Credit to (but not including) the date on which such
Letter of Credit expires, a letter of credit fee at a rate PER ANNUM equal to
the Applicable Margin for Letters of Credit on such Lender's Percentage of the
face amount of such Letter of Credit. Such letter of credit fees shall be
payable by the Borrower in arrears on the last Business Day of March, June,
September and December of each year, the first such payment to be made on the
last day of the first calendar quarter for which a Letter of Credit is first
outstanding hereunder for which no fees shall theretofore have been paid, and on
the date such Letter of Credit expires.

      (b) The Borrower agrees to pay to the Issuing Bank an issuance fee and a
renewal fee for each Letter of Credit issued hereunder, payable at the time of
issuance or renewal of such Letter of Credit, as the case may be, and
negotiation fees on each sight draft drawn under a Letter of Credit and
amendment fees in respect of the amendment of each Letter of Credit, payable on
demand, such issuance fees, renewal fees, negotiation fees and amendment fees to
be in amounts mutually agreed by the Borrower and the Issuing Bank.

      SECTION 4.6 PAYMENT OF INTEREST; CALCULATION OF INTEREST AND FEES.
Interest accrued on each Note prior to maturity (whether by acceleration or
otherwise) shall be payable:

            (a)   on Eurodollar Loans, on the last day of each applicable
                  Eurodollar Interest Period and, if such Eurodollar Interest
                  Period shall exceed three (3) months, on the day of each third
                  month during such Eurodollar Interest Period which is
                  numerically equivalent to the Eurodollar Period Commencement
                  Date for such Eurodollar Interest Period or if there exists no
                  numerically corresponding day in such month, on the last
                  Eurodollar Business Day of such month (each such date herein
                  called a "EURODOLLAR INTEREST PAYMENT DATE");

            (b)   on Domestic Loans, in arrears, on the last Business Day of
                  each March, June, September, and December of each year,
                  commencing with the first quarterly period during which
                  Domestic Loans are outstanding hereunder for which no interest
                  shall theretofore have been paid;

and at the Stated Maturity Date for each Loan. After maturity (whether by
acceleration or otherwise), interest shall be payable on demand. All interest
on Domestic Loans and all commitment and letter of credit fees due under this
Agreement shall be calculated on the basis of the actual number of days elapsed
in a year consisting of 365 days (or 366 days in a leap year, as 

                                      41
<PAGE>
applicable). All interest on the Eurodollar Loans shall be calculated on the
basis of the actual number of days elapsed in a year consisting of 360 days.
Where interest is calculated on the basis of the Alternate Base Rate, such rate
shall change simultaneously with each change in the Alternate Base Rate.

      SECTION 4.7 EURODOLLAR DEPOSITS UNAVAILABLE OR EURODOLLAR INTEREST RATE
UNASCERTAINABLE. In the event that, prior to any Eurodollar Period Commencement
Date in respect of any Eurodollar Loans, the Administrative Agent shall have
determined (which determination shall be conclusive and binding on all parties
hereto) that Dollar deposits of the relevant amount and for the relevant
Eurodollar Interest Period for such Eurodollar Loans are not available to the
Lenders in the interbank Eurodollar market or that, by reason of circumstances
affecting the interbank Eurodollar market, adequate and reasonable means do not
exist for ascertaining the Eurodollar Interest Rate applicable to such
Eurodollar Interest Period or the Required Lenders advise the Administrative
Agent that the Eurodollar Interest Rate as determined by the Administrative
Agent will not adequately and fairly reflect the cost to such Required Lenders
of maintaining or funding Eurodollar Loans for the relevant Eurodollar Interest
Period, the Administrative Agent shall promptly give notice of such
determination to the Borrower and the Lenders and (i) the Borrower's request for
a proposed Eurodollar Loan shall be deemed a request for a Domestic Loan, (ii)
any outstanding Eurodollar Loans (unless the Administrative Agent subsequent to
such determination of unavailability shall determine that such Dollar deposits
are again available) shall be converted, without any notice to or from the
Borrower, into Domestic Loans on the last day of the then current Eurodollar
Interest Period for any outstanding Eurodollar Loan, and (iii) the obligation of
the Lenders to make or maintain Eurodollar Loans shall forthwith terminate,
provided that if circumstances subsequently change so that the Lenders shall not
continue to be so affected, the Lenders shall by notice to the Borrower
reinstate their obligations to make, convert, maintain or continue Domestic
Loans as, or into, Eurodollar Loans.

      SECTION 4.8 CHANGES IN LAW RENDERING EURODOLLAR LENDING UNLAWFUL. In the
event that any change in (including the adoption of any new) applicable Laws or
regulations, or in the interpretation or application thereof by any governmental
or other regulatory authority charged with the administration thereof, should
make it unlawful for any Lender to make, continue or maintain any Loan as, or to
convert any Loan to, a Eurodollar Loan, the Commitment of such Lender to make,
continue and maintain any Loan as, and to convert any Loan to, a Eurodollar Loan
shall, upon the happening of such event, forthwith terminate and such Lender
shall, by written notice to the Borrower, declare that such Commitment has so
terminated; and if any such change or adoption shall make it unlawful for such
Lender to maintain any Eurodollar Loan made by it hereunder, such Lender shall,
upon the happening of such event, notify the Borrower thereof in writing stating
the reasons therefor, and the Borrower shall, at the maturity thereof (or such
earlier date as may be required by the relevant law, regulation, interpretation
or application), repay such Eurodollar Loan with respect to such Lender in full.
Upon the happening of any such event, such Eurodollar Loan shall automatically
convert to a Domestic Loan at the end of the current Eurodollar Interest Period
with respect thereto (or such earlier date as may be required by the relevant
law, regulation, interpretation 

                                      42
<PAGE>
or application) provided that if circumstances subsequently change so that such
Lender shall not continue to be so affected, such Lender shall by notice to the
Borrower reinstate its obligations to make, convert, maintain or continue Loans
as, or into, Eurodollar Loans.

      SECTION 4.9 SPECIAL FEES IN RESPECT OF RESERVE REQUIREMENTS. With respect
to Eurodollar Loans, the Borrower agrees to pay to each Lender on appropriate
Eurodollar Interest Payment Dates, as additional interest, such amounts as will
compensate such Lender for any cost to such Lender, from time to time, of any
reserve, special deposit, special assessment or similar capital requirements
against assets of, deposits with or for the account of, or credit extended by,
such Lender which are imposed on, or deemed applicable by, such Lender, from
time to time, under or pursuant to (i) any Law, treaty, regulation or directive
now or hereafter in effect (including, without limitation, Regulation D of the
Board of Governors of the Federal Reserve System but excluding any reserve
requirement included in the definition of Eurodollar Interest Rate in SECTION
1.1,) (ii) any interpretation or application thereof by any governmental
authority, agency or instrumentality charged with the administration thereof or
by any court, central bank or other fiscal, monetary or other authority having
jurisdiction over the Eurodollar Loans or the office of such Lender where its
Eurodollar Loans are lodged, or (iii) any requirement imposed or requested by
any court, governmental authority, agency or instrumentality or central bank,
fiscal, monetary or other authority, whether or not having the force of law. A
certificate as to the amount of any such cost or any change therein (including
calculations, in reasonable detail, showing how such Lender computed such cost
or change) shall be promptly furnished by such Lender to the Borrower and, in
the absence of manifest error, shall be rebuttable presumptive evidence of such
cost or change. The Borrower will not be responsible for paying any amounts
pursuant to this SECTION 4.9 accruing prior to 180 days prior to the receipt by
the Borrower of the certificate referred to in the preceding sentence. Within
fifteen (15) days after such certificate is furnished to the Borrower, the
Borrower will pay directly to such Lender such additional amount or amounts as
will compensate such Lender for such cost or change.

      SECTION 4.10 TAXES. All payments by the Borrower of principal of, and
interest on, the Loans and all other amounts payable hereunder shall be made
free and clear of and without deduction for any present or future income,
excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or
other charges of any nature whatsoever imposed by any taxing authority, but
excluding franchise taxes and taxes imposed on or measured by any Lender's net
income or receipts imposed on such Lender as a result of a present or former
connection between the government or taxing authority imposing such tax and such
Lender or any political subdivision or taxing authority thereof or therein
(other than a connection arising solely from such Lender having executed,
delivered or performed its obligations or received a payment under, or enforced
this Agreement or the Notes) (such non-excluded taxes, fees, duties,
withholdings, charges and other items being called "TAXES"). In the event that
any withholding or deduction from any payment to be made by the Borrower
hereunder is required in respect of any Taxes pursuant to any applicable law,
rule or regulation, or if any Taxes are directly asserted against the
Administrative Agent or any Lender with respect to any payment received by the
Administrative Agent or such Lender hereunder, the Administrative Agent or such

                                      43
<PAGE>
Lender, as the case may be, shall promptly notify the Borrower thereof, and the
Borrower will promptly pay to the Administrative Agent for its or such Lender's
account such additional amount or amounts as is necessary in order that the net
amount received by the Administrative Agent and each Lender after any
withholding or deduction and the payment of such Taxes (including any Taxes on
such additional amount) shall equal the amount such person would have received
had not such withholding or deduction been required or such Taxes been asserted.

      If the Borrower fails to pay any Taxes when due to the appropriate taxing
authority, the Borrower shall indemnify the Lenders for any incremental Taxes,
interest or penalties that may become payable by any Lender as a result of any
such failure. For purposes of this SECTION 4.10, a distribution hereunder by the
Administrative Agent or any Lender to or for the account of any Lender shall be
deemed a payment by the Borrower.

      Upon the request of the Borrower or the Administrative Agent, each Lender
that is organized under the laws of a jurisdiction other than the United States
shall, prior to the due date of any payments in respect of the Borrowings,
execute and deliver to the Borrower and the Administrative Agent, on or about
January 15 of each calendar year, one or more (as the Borrower or the
Administrative Agent may reasonably request) United States Internal Revenue
Service Forms 4224 or Forms 1001 or such other forms or documents (or successor
forms or documents), appropriately completed, as may be applicable to establish
the extent, if any, to which a payment to such Lender is exempt from withholding
or deduction of Taxes.

      SECTION 4.11 REASONABLE EFFORTS. Each Lender agrees that it will use all
reasonable efforts in order to avoid or to minimize, as the case may be, the
payment by the Borrower of any additional amounts under SECTION 4.9, SECTION
4.10 or SECTION 4.12 or the subjecting of any payment by the Borrower to any
withholding tax, and that it will, as promptly as practicable, notify the
Borrower of the existence of any event which will require the payment by the
Borrower of any such additional amounts or the subjecting of any payment by the
Borrower to any withholding tax; PROVIDED, HOWEVER, that the foregoing shall not
in any way affect the rights of any Lender or the obligations of the Borrower
under said Sections, and PROVIDED FURTHER that no Lender shall be obligated to
make its Eurodollar Loans hereunder at any office located in the United States
of America, and PROVIDED FURTHER that no Lender shall be required to use any
such efforts that are disadvantageous to such Lender in the sole opinion of such
Lender.

      SECTION 4.12 INCREASED COSTS. If (i) Regulation D of the Board of
Governors of the Federal Reserve System, or (ii) after the date hereof, the
adoption of any applicable Law or treaty or any change in any applicable Law or
treaty or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or any
office of such Lender designated from time to time by such Lender as the office
which shall be making or maintaining the Eurodollar Loans of such Lender
hereunder or through which such Lender will be determining its Eurodollar
Interest Rate (herein called a "EURODOLLAR OFFICE"))

                                      44
<PAGE>
with any request or directive (whether or not having the force of law) of any
such authority, central bank or comparable agency:

            (a)   shall subject any Lender (or any Eurodollar Office of such
                  Lender) to any tax, levy, impost, fee, duty, assessment or
                  other charge with respect to its Eurodollar Loans, its Notes
                  or its obligation to make Eurodollar Loans, or shall change
                  the basis of taxation of payments to any Lender of the
                  principal of or interest on its Eurodollar Loans or any other
                  amounts due under this Agreement in respect of its Eurodollar
                  Loans or its obligation to make Eurodollar Loans (except for
                  changes in the rate of tax imposed on or measured by the
                  overall net income or receipts of such Lender or its
                  Eurodollar Office imposed by the jurisdiction in which such
                  Lender's principal office or its Eurodollar Office is
                  located); or

            (b)   shall impose, modify or deem applicable any reserve
                  (including, without limitation, any reserve imposed by the
                  Board of Governors of the Federal Reserve System, but
                  excluding any reserve included in the determination of the
                  Eurodollar Interest Rate pursuant to SECTION 1.1), special
                  deposit, special assessment or similar capital requirement
                  against assets of, deposits with or for the account of, or
                  credit extended by, any Lender (or any Eurodollar Office of
                  such Lender); or

            (c)   shall impose on any Lender (or its Eurodollar Office) any
                  other condition affecting this Agreement, its Eurodollar
                  Loans, its Notes or its obligation to make Eurodollar Loans,

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D referred to above, to impose a cost on) such Lender (or any
Eurodollar Office of such Lender) of making or maintaining any Eurodollar Loan,
or to reduce the amount of any sum received or receivable by such Lender (or any
Eurodollar Office of such Lender) under this Agreement or under its Notes with
respect thereto, then within fifteen (15) days after demand by such Lender
(which demand shall be accompanied by a certificate setting forth the basis of
such demand and including calculations in reasonable detail), the Borrower shall
pay directly to such Lender such additional amount or amounts as will compensate
such Lender for such costs or expenses. The Borrower will not be responsible for
paying any amounts pursuant to this SECTION 4.12 accruing prior to 180 days
prior to the receipt by the Borrower of the certificate referred to in the
preceding sentence. Any certificate as to any such cost or expense submitted by
such Lender to the Borrower shall be rebuttable presumptive evidence of such
cost or expense. In determining such amount, any Lender may use any method of
averaging and attribution that it (in its sole and absolute discretion) shall
deem applicable.

      SECTION 4.13 DISCRETION OF THE LENDERS AS TO MANNER OF FUNDING.
Notwithstanding any provision of this Agreement to the contrary, each Lender
shall be entitled to fund and maintain its funding of all or any part of its
Loans in any manner it sees fit, it being

                                      45
<PAGE>
understood, however, that for the purposes of this Agreement all determinations
hereunder shall be made as if such Lender had actually funded and maintained
each Eurodollar Loan during each Eurodollar Interest Period for such Eurodollar
Loan through the purchase of deposits having a maturity corresponding to such
Eurodollar Interest Period and bearing an interest rate equal to the Eurodollar
Interest Rate for such Eurodollar Interest Period. It is understood by the
parties hereto that this SECTION 4.13 is not intended to, nor shall it be
construed so as to, relieve any Lender of any obligation to make a Loan
hereunder pursuant to the other provisions of this Agreement.

      SECTION 4.14 EURODOLLAR LOAN-RELATED INDEMNIFICATION PROVISIONS. UPON
DEMAND BY ANY LENDER, THE BORROWER SHALL INDEMNIFY SUCH LENDER AGAINST ANY
ACTUAL LOSS OR EXPENSE WHICH SUCH LENDER MAY SUSTAIN OR INCUR (BUT NOT ANY
PENALTY OR PREMIUM), AS A CONSEQUENCE OF (I) THE BORROWER'S FAILURE TO MAKE A
PRINCIPAL OR INTEREST PAYMENT WITH RESPECT TO ANY EURODOLLAR LOANS ON THE DUE
DATE THEREOF, (II) ANY PAYMENT, PREPAYMENT (MANDATORY OR OPTIONAL) OR CONVERSION
OF EURODOLLAR LOANS BY THE BORROWER ON ANY DATE OTHER THAN ON THE LAST DAY OF
ANY RELEVANT EURODOLLAR INTEREST PERIOD, (III) ANY FAILURE BY THE BORROWER TO
BORROW, CONTINUE, CONVERT INTO OR PREPAY A EURODOLLAR LOAN ON THE DATE FOR SUCH
BORROWING, CONTINUATION, CONVERSION OR PREPAYMENT SPECIFIED IN THE RELEVANT
BORROWING REQUEST, OR NOTICE OF CONVERSION, CONTINUATION OR PREPAYMENT MADE BY
THE BORROWER TO THE ADMINISTRATIVE AGENT, (IV) ANY CONVERSION ON ANY DATE OTHER
THAN ON THE LAST DAY OF ANY RELEVANT EURODOLLAR INTEREST PERIOD BY REASON OF THE
OPERATION OF SECTION 4.7 OR 4.8, OR (V) SUCH LENDER'S BEING A DECLINING LENDER
OR REDUCED DECLINING LENDER AS PROVIDED IN SECTION 2.7(C) OR SUCH LENDER BEING
REPLACED PURSUANT TO SECTION 4.15, INCLUDING IN ALL INSTANCES, BUT NOT LIMITED
TO, ANY LOSS OR EXPENSE SUSTAINED OR INCURRED IN LIQUIDATING OR EMPLOYING
DEPOSITS FROM THIRD PARTIES ACQUIRED TO EFFECT, FUND OR MAINTAIN SUCH EURODOLLAR
LOANS OR ANY PART THEREOF. A certificate from a Lender as to the amount of any
such loss or expense to such Lender, specifying the basis upon which such loss
or expense is computed (and including calculations in reasonable detail), shall,
in the absence of manifest error, be rebuttable presumptive evidence of such
loss or expense. Within fifteen (15) days after such certificate is furnished to
the Borrower, the Borrower will pay directly to such Lender such additional
amount or amounts as will compensate such Lender for such loss or expense.

      SECTION 4.15 REPLACEMENT OF LENDER ON ACCOUNT OF INCREASED COSTS,
EURODOLLAR LENDING UNLAWFUL, RESERVE REQUIREMENTS, TAXES, CERTAIN DISSENTS, ETC.
If any Lender is owed increased costs under SECTION 2.6 above, if any Lender
shall claim the inability to make or maintain Eurodollar Loans pursuant to
SECTION 4.8 above, if any Lender is owed any cost or expense pursuant to SECTION
4.9 or 4.12 above, if any payment to any Lender by the Borrower is subject to
any withholding tax pursuant to SECTION 4.10, or if any Lender does not agree to
an amendment, modification, waiver or consent, the Borrower shall have the
right, if no Event of Default or Unmatured Event of Default then exists, to
replace such Lender with another bank or financial institution PROVIDED that (i)
if it is not a Lender or an affiliate thereof, such bank or financial
institution shall be reasonably acceptable to the Agents and the Issuing Bank
and (ii) such bank or financial institution shall unconditionally offer in
writing (with a copy to the Administrative Agent and the Documentation Agent) to
purchase, in accordance with SECTION 

                                      46
<PAGE>
14.6 hereof and Section 7.5(i) of the Participation Agreement, all of such
Lender's rights and obligations under this Agreement and the Notes and the
appropriate PRO RATA share of such Lender's A-Notes, Lessor's A-Invested Amount,
B-Notes, and Lessor's B-Invested Amount, without recourse or expense to, or
warranty by, such Lender being replaced for a purchase price equal to the
aggregate outstanding principal amount of the Note payable to such Lender PLUS
such Lender's Percentage of any outstanding Reimbursement Obligation, PLUS any
accrued but unpaid interest on such Note and such Reimbursement Obligations PLUS
the principal and stated amount of such A-Notes, Lessor's A-Invested Amount,
B-Notes, and Lessor's B-Invested Amount, PLUS any accrued but unpaid Fixed Rent,
PLUS accrued but unpaid fees in respect of such Lender's Borrowings and
Percentage of the Commitments hereunder to the date of such purchase on a date
therein specified. If such Lender accepts such purchase offer and such purchase
is consummated, the Borrower shall be obligated to pay, simultaneously with such
purchase and sale, the increased costs, amounts, expenses and taxes under
SECTIONS 2.6, 4.8, 4.9, 4.10, and 4.12 above, all breakage fees payable under
SECTION 4.14 and all other costs, fees and expenses payable to such Lender
hereunder and under the Operative Documents and under the Operative Loan
Documents (as defined in the Operative Documents), to the date of such purchase
as well as all other Obligations due and payable to or for the benefit of such
Lender; PROVIDED, that (x) if such Lender accepts such an offer and such bank or
financial institution fails to purchase such rights and obligations on such
specified date in accordance with the terms of such offer, the Borrower shall
continue to be obligated to pay the increased costs, amounts, expenses and taxes
under SECTIONS 2.6, 4.8, 4.9, 4.10 and 4.12 above to such Lender and (y) if such
Lender fails to accept such purchase offer, the Borrower shall not be obligated
to pay such Lender such increased costs pursuant to SECTIONS 2.6, 4.8, 4.9, 4.10
and 4.12 above from and after the date of such purchase offer.

      SECTION 4.16 MAXIMUM INTEREST. It is the intention of the parties hereto
to conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the obligations of the Borrower to each Lender under
this Agreement shall be subject to the limitation that payments of interest
shall not be required to the extent that receipt thereof would be contrary to
provisions of law applicable to such Lender limiting rates of interest which may
be charged or collected by such Lender. Accordingly, if the transactions
contemplated hereby would be usurious under applicable law (including the
Federal and state laws of the United States of America, or of any other
jurisdiction whose laws may be mandatorily applicable) with respect to a Lender
then, in that event, notwithstanding anything to the contrary in this Agreement,
it is agreed as follows:

            (a)   the provisions of this SECTION 4.16 shall govern and control;

            (b)   the aggregate of all consideration which constitutes interest
                  under applicable law that is contracted for, charged or
                  received under this Agreement, or under any of the other
                  aforesaid agreements or otherwise in connection with this
                  Agreement by such Lender shall under no circumstances exceed
                  the maximum amount of interest allowed by applicable law (such
                  maximum lawful interest rate, if any, with respect 

                                      47
<PAGE>
                  to such Lender herein called the "HIGHEST LAWFUL RATE"), and
                  any excess shall be credited to the Borrower by such Lender
                  (or, if such consideration shall have been paid in full, such
                  excess refunded to the Borrower);

            (c)   all sums paid, or agreed to be paid, to such Lender for the
                  use, forbearance and detention of the indebtedness of the
                  Borrower to such Lender hereunder shall, to the extent
                  permitted by applicable law, be amortized, prorated, allocated
                  and spread throughout the full term of such indebtedness until
                  payment in full so that the actual rate of interest is uniform
                  throughout the full term thereof; and

            (d)   if at any time the interest provided pursuant to SECTION 4.1
                  together with any other fees payable pursuant to this
                  Agreement and deemed interest under applicable law, exceeds
                  that amount which would have accrued at the Highest Lawful
                  Rate, the amount of interest and any such fees to accrue to
                  such Lender pursuant to this Agreement shall be limited, not
                  withstanding anything to the contrary in this Agreement to
                  that amount which would have accrued at the Highest Lawful
                  Rate, but any subsequent reductions, as applicable, shall not
                  reduce the interest to accrue to such Lender pursuant to this
                  Agreement below the Highest Lawful Rate until the total amount
                  of interest accrued pursuant to this Agreement and such fees
                  deemed to be interest equals the amount of interest which
                  would have accrued to such Lender if a varying rate per annum
                  equal to the interest provided pursuant to SECTION 4.1 had at
                  all times been in ef fect, PLUS the amount of fees which would
                  have been received but for the effect of this SECTION 4.16.

For purposes of Article 5069-1.04, Vernon's Texas Civil Statutes, as amended, to
the extent, if any, applicable to a Lender, the Borrower agrees that the Highest
Lawful Rate shall be the "indicated (weekly) rate ceiling" as defined in said
Article, provided that such Lender may also rely, to the extent permitted by
applicable laws, on alternative maximum rates of interest under other laws
applicable to such Lender if greater.

      Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15 (which regulates certain
revolving credit loan accounts and revolving tri-party accounts) shall not apply
to this Agreement or the Notes.

                        OF THE COMMITMENTS; PREPAYMENTS

      SECTION 5.1 VOLUNTARY REDUCTION OR TERMINATION OF THE COMMITMENTS. The
Borrower may from time to time on at least three (3) Business Days' prior
written or telegraphic notice received by the Administrative Agent (which shall
promptly advise each Lender thereof) permanently reduce the Commitment Amount or
the Letter of Credit Commitment Amount (such reduction to be made PRO RATA among
the Lenders according to their respective Percentages) but only upon repayment
of the amount, if any, by which the aggregate outstandings under such facility
exceeds the then reduced Commitment Amount in accordance with SECTION 5.7;
PROVIDED, HOWEVER, that (i) if as a result thereof, the Borrower shall prepay
Eurodollar Loans on any day other than the last day of the relevant Eurodollar
Interest Period for such Eurodollar Loans then it shall also pay any loss or
expense pursuant to SECTION 4.14 and (ii) any permanent reduction shall be in a
minimum principal amount of $5,000,000 and in integral multiples of $100,000.
The Borrower may at any time on like notice, terminate all of the Commitments
upon payment in full of the Notes, all other Obligations with respect to the
Loans and all Letter of Credit Liabilities (including, without limitation, all
increased costs pursuant to SECTION 2.6, breakage fees pursuant to SECTION 4.14
and all other fees, costs and expenses) owing under this Agreement.
Additionally, any election by the Borrower to reduce the Total Committed Amount
pursuant to SECTION 2.7(C)(I), (II) or (III) shall be deemed to be a permanent
reduction of the Total Committed Amount and the Commitment Amount (such
reduction to be made among the Accepting Lenders and the Reduced Declining
Lenders according to such SECTION 2.7(C)(I), (II) or (III), as the case may be).

      SECTION 5.2 VOLUNTARY PREPAYMENTS. The Borrower may from time to time,
upon at least one (1) Business Day for Domestic Loans and three (3) Business
Days for Eurodollar Loans prior written or telegraphic notice received by the
Administrative Agent (which shall promptly advise each Lender thereof), prepay
the Loans in whole or in part, without premium or penalty; PROVIDED, HOWEVER,
that the Borrower may only prepay Eurodollar Loans in whole or in part on the
last day of the relevant Eurodollar Interest Period for such Eurodollar Loan
UNLESS the Borrower pays all losses and expenses pursuant to SECTION 4.14 and
PROVIDED FURTHER after giving effect to such prepayment, the outstanding
Eurodollar Loans, if any, having a Eurodollar Interest Period ending on the same
date, if any, shall be in a minimum principal amount of $5,000,000. Any
voluntary partial prepayment shall be in a minimum principal amount of
$1,000,000 and in integral multiples of $100,000. Any voluntary prepayment of
principal of the Loans shall include accrued interest to the date of prepayment
on the principal amount being prepaid.

      SECTION 5.3 MANDATORY SCHEDULED REDUCTIONS OF THE COMMITMENT AMOUNT. On
the last Business Day of each calendar quarter, commencing on the Initial
Commitment Amortization Date and continuing until the Commitment Termination
Date, the Commitment Amount shall, without any further action, automatically and
permanently be reduced by

                                      49

$8,593,750, provided, however, that on the Commitment Termination Date, the
Commitment Amount shall be zero.

      SECTION 5.5 MANDATORY PREPAYMENTS AND REDUCTION OF COMMITMENT AMOUNT ON
ACCOUNT OF ASSET TRANSFERS.

            (i)   If, at any time and from time to time after the date hereof,
                  the Borrower or any of its Subsidiaries shall Transfer any
                  Asset as permitted by SECTION 9.3.8(II), the Commitment Amount
                  shall be automatically and permanently reduced (1) on the
                  earlier to occur of (A) five (5) Business Days after the date
                  of receipt by the Borrower or any Subsidiary of the Borrower
                  of the consideration on account of such Transfer (other than a
                  Transfer pursuant to the exercise of an Option to Purchase)
                  and (B) the date which is 15 days after the date of such
                  Transfer and (2) on the earlier to occur of (A) five (5)
                  Business Days after the date of receipt by the Borrower or any
                  Subsidiary of the Borrower of the consideration due on account
                  of any such Transfer made pursuant to the exercise of an
                  Option to Purchase or (B) the date which is 25 days after the
                  date of any such Transfer made pursuant to the exercise of an
                  Option to Purchase. Such mandatory reduction of the Commitment
                  Amount shall be in an amount equal to the Net Proceeds
                  received or to be received from such Transfer or, if such
                  Transfer is to an Affiliate of the transferor, the higher of
                  (x) the Fair Market Value of the Asset so transferred and (y)
                  the Net Proceeds received or to be received.

            (ii)  On each date when a reduction in the Commitment Amount
                  pursuant to this SECTION 5.5 is effective, the Borrower shall
                  make any and all prepayments required by SECTION 5.7.

<PAGE>
principal amount of the Loans and all other Obligations shall automatically be
and become immediately due and payable, all without notice or demand of any
kind; and, in the case of any other Event of Default, the Administrative Agent
may (and, upon written request of the Required Lenders, shall) declare the
Commitments of the Lenders hereunder (if not theretofore terminated) to be
terminated and/or declare all or any portion of the outstanding principal amount
of the Loans and other Obligations to be due and payable, whereupon the

immediately terminate and/or, as the case may be, the full unpaid amount of such
Loans and other Obligations which shall be so declared due and payable shall be
and become immediately due and payable, all without notice of any kind. The
Administrative Agent shall promptly advise the Borrower and each Lender of any
such declaration, but failure to do so shall not impair the effect of such
declaration. Notwithstanding the foregoing, the effect as an Event of Default of
any event described in SECTION 12.1.1, or SECTION 12.1.4 with respect to the
Borrower, may be waived by the written concurrence of the holders of one hundred
percent (100%) of the aggregate unpaid principal amount of the Borrowings and
the effect as an Event of Default of any other event described in SECTION 12.1
may be waived by the written concurrence of the Required Lenders.

      SECTION 12.3 CASH COLLATERALIZATION OF LETTERS OF CREDIT UPON EVENT OF
DEFAULT. Upon the occurrence of an Event of Default, an amount equal to the
amount of the then contingent liability of the Issuing Bank (and the other
Lenders) under each outstanding Letter of Credit shall, at the option of the
Majority Lenders and without demand upon or notice to the Borrower, be deemed
(as between the Borrower, Issuing Bank and the Lenders) to have been paid or
disbursed by the Issuing Bank (and the other Lenders) under such Letter of
Credit (notwithstanding that such amount may not in fact have been so paid or
disbursed), and the Borrower shall be obligated forthwith, upon demand or notice
to the Borrower, to reimburse the Lenders for, by depositing with the Collateral
Agent, which amount may be invested as provided in SECTION 2.4.4, the amount
deemed to have been so paid or disbursed. Any amounts so received by the
Collateral Agent pursuant to the provisions of the preceding sentence shall be
held as collateral security as provided in SECTION 2.4.4 until such time as such
Event of Default is waived or remedied, at which time, if no other Event of
Default shall then exist, any such cash collateral and any interest thereon not
theretofore applied to reduce amounts payable by the Borrower to the Issuing
Bank under such Letter of Credit and not required to remain on deposit as a
result of SECTION 5.7 shall be returned promptly to the Borrower.

                                 ARTICLE XIII

        THE ADMINISTRATIVE AGENT, DOCUMENTATION AGENT AND ISSUING BANK

      SECTION 13.1AUTHORIZATION. Each Lender and the holder of each Note
authorizes each of the Administrative Agent, the Documentation Agent and the
Issuing Bank to act on behalf of such Lender or holder to the extent provided
herein or in any document or instrument delivered hereunder or in connection
herewith, and to take such other action as may be reasonably incidental thereto.
The Lenders hereby further authorize the Collateral Agent to release any
Collateral constituting any interest in a Guarantor or a Subsidiary owning an
interest 

                                       86
<PAGE>
in any Guarantor in connection with a disposition of a minority interest in such

      SECTION 13.2 POWER. Each of the Administrative Agent and the Documentation
Agent shall have and may exercise such powers under this Agreement and the other
Loan Documents as are specifically delegated to the Administrative Agent and the
Documentation Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. The Administrative Agent and the Documentation
Agent and the Issuing Bank shall not have any implied duties or any obligation
to take any action under this Agreement except any action specifically provided
by this Agreement to be taken by the Administrative Agent or the Documentation
Agent or the Issuing Bank, as the case may be.

      SECTION 13.3 INDEMNIFICATION OF THE ADMINISTRATIVE AGENT, THE

hereby indemnify each of the Administrative Agent, the Documentation Agent and
the Issuing Bank (to the extent not reimbursed by the Borrower or the
Guarantors) ratably according to the Lenders' respective Percentages from and
against any and all claims, liabilities, obligations, losses, damages,
penalties, costs, expenses and disbursements of any kind or nature whatsoever
which may be paid by, imposed on, incurred by, or asserted against any of the
Administrative Agent, the Documentation Agent or the Issuing Bank in any way
relating to or arising out of this Agreement, any Note, any Loan Document, any
Letter of Credit, or any other document executed in connection herewith or any
action taken or omitted by any of the Administrative Agent, the Documentation
Agent or the Issuing Bank under this Agreement, any Note, any other Loan
Document or any other document executed in connection herewith or therewith,
PROVIDED that no Lender shall be liable for any portion of such claims,
liabilities, obligations, losses, damages, penalties, costs, expenses and
disbursements resulting from such Administrative Agent's, Documentation Agent's
or Issuing Bank's gross negligence or wilful misconduct. Without limiting the
generality of the foregoing, each Lender agrees to reimburse each of the
Administrative Agent, the Documentation Agent and the Issuing Bank promptly upon
demand for its ratable share of any out-of-pocket expenses (including reasonable
counsel fees) incurred by any of the Administrative Agent, the Documentation
Agent or the Issuing Bank under, or in the enforcement of, or for legal advice
in respect of rights or responsibilities under, this Agreement, any Note, any
other Loan Document or any other document executed in connection herewith or
therewith to the extent that the Administrative Agent, the Documentation Agent
and the Issuing Bank are not reimbursed for such expenses by the Borrower or any
Guarantor PROVIDED that no Lender shall be liable for any such expenses
resulting from the Administrative Agent's, the Documentation Agent's or the
Issuing Bank's gross negligence or wilful misconduct. If any indemnity furnished
to any of the Administrative Agent, the Documentation Agent or the Issuing Bank
for any purpose shall, in the opinion of such Administrative Agent, such
Documentation Agent or such Issuing Bank, be insufficient or become impaired,
such Administrative Agent, Documentation Agent or such Issuing Bank may call for
additional indemnity and not commence or cease to do the acts indemnified
against until such additional indemnity is furnished.

      SECTION 13.4 ACTION ON INSTRUCTIONS OF THE REQUIRED LENDERS. As to any
matters not expressly provided for by this Agreement (including, without
limitation, enforcement or collection of the Notes), neither the Administrative
Agent, the Documentation Agent nor the Issuing Bank shall be required to
exercise any discretion or take any action, but the Administrative Agent, the
Documentation Agent and the Issuing Bank 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 Required Lenders, and such instructions
shall be binding upon the Lenders (including, without limitation, all subsequent
holders of the Notes); PROVIDED, HOWEVER, that neither the Administrative Agent,
the Documentation Agent the Issuing Bank shall be required to take any action
which exposes the Administrative Agent, the Documentation Agent or the Issuing
Bank to personal liability or which is contrary to this Agreement, any Loan
Document or applicable law; PROVIDED, FURTHER, HOWEVER, that neither the
Administrative Agent, the Documentation Agent nor the Issuing Bank shall be
required to do any act hereunder or under any Loan Document or any other
document or instrument delivered hereunder or in connection herewith or take any
action toward the execution or enforcement of the agency hereby created, or to
prosecute or defend any suit in respect of this Agreement, any Loan Document,
any Letter of Credit or the Notes or any collateral security, unless the
Administrative Agent, the Documentation Agent and the Issuing Bank are fully and
specifically indemnified to their satisfaction by the Lenders against any and
all claims, liabilities, obligations, losses, damages, penalties, costs,
disbursements and expenses of any kind or nature whatsoever relating to or
arising out of such action (other than any portions of such claims, liabilities,
obligations, losses, damages, penalties, costs, disbursements and expenses
resulting from such Administrative Agent's, Documentation Agent's or Issuing
Bank's gross negligence or wilful misconduct). The relationship between the
Administrative Agent, the Documentation Agent and the Issuing Bank on the one
hand and the Lenders on the other hand is and shall be that of agent and
principal only and nothing herein contained shall be construed to constitute the
Administrative Agent, the Documentation Agent or the Issuing Bank a trustee for
any holder of a Note or of a participation therein or in a Letter of Credit nor
to impose on the Administrative Agent, the Documentation Agent or the Issuing
Bank duties and obligations other than those expressly provided for herein.

      SECTION 13.5 EXCULPATION.  Neither the Administrative Agent nor the
Documentation Agent nor any of their respective directors, officers, employees

Loan Document or any other instrument or document delivered hereunder or in
connection herewith, (ii) be responsible for the validity, genuineness,
perfection, effectiveness, enforceability, existence, value or enforcement of
any guaranty or collateral security, (iii) be under any duty to inquire into or
pass upon any of the foregoing matters, or to make any inquiry concerning the
performance by the Borrower or any other Obligor of its obligations, or (iv) in
any event, be liable as such for any action taken or omitted by it or them,
except for its or their own gross negligence or willful misconduct. The agency
hereby created shall in no way impair or affect any of the rights and powers of,
or impose any duties or obligations upon, the Administrative Agent and the
Documentation Agent in their individual capacity.

                                       88

      SECTION 13.6 EMPLOYMENT OF COUNSEL, ETC. The Administrative Agent, the
Documentation Agent and the Issuing Bank may execute any of their respective
duties under this Agreement, any Loan Document and any instrument, agreement or
document executed, issued or delivered pursuant hereto or thereto or in
connection herewith or therewith, by or through employees, agents,
correspondents, confirming banks, and attorneys-in-fact and shall not be
answerable to the Lenders for the default or misconduct of any such employee,
agent, correspondents, confirming banks, or attorney-in-fact selected by it with
reasonable care. The Administrative Agent, the Documentation Agent and the
Issuing Bank shall be entitled to rely on advice of counsel (including counsel
who are the employees of the Administrative Agent, the Documentation Agent and
the Issuing Bank) selected by such Administrative Agent or such Documentation
Agent or such Issuing Bank concerning all matters pertaining to the agency
hereby created and its duties to the Lenders under this Agreement, any Loan
Document and any instrument, agreement or document executed, issued or delivered
pursuant hereto or thereto or in connection herewith or therewith.

      SECTION 13.7 RELIANCE ON DOCUMENTS. Each of the Administrative Agent, the
Documentation Agent and the Issuing Bank shall be entitled to rely upon any
notice, consent, waiver, amendment, certificate, affidavit, letter, telegram,
statement, paper or document believed by it to be genuine and correct and to
have been signed or sent by the proper Person or Persons.

      SECTION 13.8 CREDIT INVESTIGATION. Each Lender acknowledges that it has
made such inquiries and taken such care on its own behalf (including, without
limitation, that it had this Agreement, the form of its Note and the Guaranties,
the Security Documents and such other documents or matters as it deemed
appropriate relating hereto and thereto reviewed by its own legal counsel as it
deemed appropriate, and it is satisfied with the form of this Agreement, its
Note and the Security Documents) as would have been the case had the Commitments
hereunder been granted and the Borrowings made and the Letters of Credit issued
directly by such Lender to the Borrower without the intervention of the
Collateral Agent, the Administrative Agent, the Documentation Agent, the Issuing
Bank or any other Lender. Each Lender agrees and acknowledges that neither the
Administrative Agent nor the Documentation Agent nor the Issuing Bank make any
representations or warranties about the creditworthiness of the Borrower, any
Subsidiary, any Guarantor, the Parent Company, the Holding Company or any other
party to this Agreement or with respect to the legality, validity, sufficiency
or enforceability of this Agreement, any Note, any other Loan Document or the
existence or value of any collateral security therefor.

      SECTION 13.9 RESIGNATION. Any of the Administrative Agent, the Issuing
Bank, and the Documentation Agent may resign as such at any time upon at least
thirty (30) days prior notice to the Borrower and the Lenders. In the event of
any such resignation of the Administrative Agent, the Borrower, with the consent
of the Documentation Agent, shall as promptly as practicable appoint a successor
agent to the Administrative Agent, which shall be the Documentation Agent. In
the event no such successor is appointed, the Required Lenders shall as promptly
as practicable appoint a successor agent to such resigning Administrative 

                                       89
<PAGE>
Agent. In the event no such successor is so appointed within thirty (30) days of
any such notice, any Lender may apply to a court of competent jurisdiction for
the appointment of a successor agent hereunder to such resigning Administrative
Agent. After any retiring Administrative Agent's or Documentation Agent's
resignation hereunder as the Administrative Agent or the Documentation Agent or
the Issuing Bank, the provisions of (i) this ARTICLE XIII shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was the
Administrative Agent or Documentation Agent or the Issuing Bank, as the case may
be, under this Agreement; (ii) SECTION 14.8 shall continue to inure to its
benefit; and ARTICLE II shall continue to inure to the benefit of the Issuing
Bank.

Loan Document, be defined or made (as the case may be) in accordance with
generally accepted accounting principles ("GAAP") applied (in the case of

faith negotiations for an agreement to revise such financial covenants or the
definitions of "LEVERAGE RATIO" or "CONSOLIDATED STOCKHOLDERS' EQUITY" or

      SECTION 14.6 SALES AND TRANSFERS, ETC., OF BORROWINGS AND NOTES;
PARTICIPATIONS IN BORROWINGS AND NOTES.

            (a)   Any Lender may at any time sell to one or more banks or other
                  entities (other than a direct competitor of the Borrower or
                  any of its Subsidiaries or a person engaged as one of its
                  principal activities in the Hydrocarbons transportation,
                  marketing or storage business ("PARTICIPANTS")) participating
                  interests in any Borrowing owing to such Lender, any Note held
                  by such Lender, any Commitment of such Lender or any other
                  interest of such Lender hereunder, PROVIDED that no Lender may
                  sell any participating interests in any such Borrowing, Note,
                  Commitment or other interest hereunder without also selling to
                  such Participant the appropriate PRO RATA share of such
                  Borrowings, Notes, Commitments and other interests hereunder
                  and the appropriate PRO RATA share of the A-Notes, the
                  Lessor's A-Invested Amount, the B-Notes and the Lessor's
                  B-Invested Amount under the Operative Documents and the
                  Operative Loan Documents (as defined in the Operative
                  Documents), and PROVIDED FURTHER that no Lender shall
                  transfer, grant or assign any participation under which the
                  participant shall have rights to approve any amendment to or
                  waiver of this Agreement except to the extent such amendment
                  or waiver would (i) increase the amount of such Lender's
                  Commitment, (ii) reduce the principal of, or interest on, any
                  of such Lender's Borrowings, or any fees payable to such
                  Lender hereunder, (iii) postpone any date fixed for any

                                       92
<PAGE>
                  scheduled payment of principal of, or interest on, any of such
                  Lender's Borrowings, or any fees or other amounts payable to
                  such Lender hereunder or (iv) release all or substantially all
                  collateral security for any Obligation (including, without
                  limitation, any Guaranty), except as otherwise specifically
                  provided in any Loan Document. In the event of any such sale
                  by a Lender of participating interests to a Participant, such
                  Lender's obligations under this Agreement to the other parties
                  to this Agreement shall remain unchanged, such Lender shall
                  remain solely responsible for the performance thereof, such
                  Lender shall remain the holder of any such Note for all
                  purposes under this Agreement and the Borrower, the
                  Administrative Agent and the Documentation Agent shall
                  continue to deal solely and directly with such Lender in
                  connection with such Lender's rights and obligations under
                  this Agreement. The Borrower agrees that if amounts
                  outstanding under this Agreement and the Notes are due and
                  unpaid, or shall have been declared or shall have become due
                  and payable upon the occurrence of an Event of Default, each
                  Participant shall be deemed to have the right of setoff in
                  respect of its participating interest in amounts owing under
                  this Agreement and any Note to the same extent as if the
                  amount of its participating interest were owing directly to it
                  as a Lender under this Agreement or any Note; PROVIDED that
                  such right of setoff shall be subject to the obligation of
                  such Participant to share with the Lenders, and the Lenders
                  agree to share with such Participant, as provided in SECTION
                  7.2. The Borrower also agrees that each Participant shall be
                  entitled to the benefits of SECTIONS 2.6, 4.9, 4.12 and 4.14
                  with respect to its participation in the Commitments and the
                  Borrowings outstanding from time to time; PROVIDED that no
                  Participant shall be entitled to receive any greater amount
                  pursuant to such Sections than the transferor Lender would
                  have been entitled to receive in respect of
                  the amount of the participation transferred by such transferor
                  Lender to such Participant had no such transfer occurred.

            (b)   Any Lender may at any time sell to any Lender or any affiliate
                  thereof, and, with the consent of the Administrative Agent and
                  the Issuing Bank and the Borrower (which shall not be
                  unreasonably withheld or delayed), to one or more banks or
                  financial institutions ("PURCHASING LENDERS") all or any part
                  of its rights and obligations under this Agreement, the Notes
                  and the other Loan Documents, pursuant to an Assignment and
                  Acceptance in the form attached as EXHIBIT 14.6 hereto,
                  executed by such Purchasing Lender, such transferor Lender
                  (and, in the case of a Purchasing Lender which is not then a
                  Lender or an affiliate thereof, consented to by the Borrower
                  and the Administrative Agent and the Issuing Bank) and the
                  Administrative Agent and delivered to the Administrative
                  Agent; PROVIDED that each such sale to a Purchasing Lender
                  shall be in an amount of $5,000,000 or more; and PROVIDED,
                  FURTHER, that 

                                       93
<PAGE>
                  no Lender may sell any Loans to a Purchasing Lender without
                  also selling to such Purchasing Lender the appropriate PRO
                  RATA share of its Borrowings and participations in Letters of
                  Credit hereunder, and its Commitments hereunder and the
                  appropriate PRO RATA share of the A-Notes, the Lessor's
                  A-Invested Amount, the B-Notes and the Lessor's B-Invested
                  Amount under the Operative Documents and the Operative Loan
                  Documents (as defined in the Operative Documents). Upon such
                  execution, delivery and acceptance, from and after the
                  Transfer Effective Date determined pursuant to such Assignment
                  and Acceptance (x) the Purchasing Lender thereunder shall be a
                  party hereto and, to the extent provided in such Assignment
                  and Acceptance, have the rights and obligations of a Lender
                  hereunder and under the other Loan Documents with a Commitment
                  as set forth therein and (y) the transferor Lender thereunder
                  shall, to the extent provided in such Assignment and
                  Acceptance be released from its obligations under this
                  Agreement and under the other Loan Documents (and, in the case
                  of an Assignment and Acceptance covering all or the remaining
                  portion of a transferor Lender's rights and obligations under
                  this Agreement and under the other Loan Documents, such
                  transferor Lender shall cease to be a party hereto). Such
                  Assignment and Acceptance shall be deemed to amend this
                  Agreement to the extent, and only to the extent, necessary to
                  reflect the addition of such Purchasing Lender and the
                  resulting adjustment of Commitments and Percentages arising
                  from the purchase by such Purchasing Lender of all or a
                  portion of the rights and obligations of such transferor
                  Lender under this Agreement, the Notes and the other Loan
                  Documents. On or prior to the Transfer Effective Date
                  determined pursuant to such Assignment and Acceptance, the
                  Borrower at its own expense, shall execute and deliver to the
                  Administrative Agent in exchange for any surrendered Note, a
                  new Note to the order of such Purchasing Lender in an amount
                  equal to the Commitments assumed by it pursuant to such
                  Assignment and Acceptance, and, if the transferor Lender has
                  retained a Commitment or Borrowing hereunder, a new Note to
                  the order of the transferor Lender in an amount equal to the
                  Commitments or Borrowings retained by it hereunder. Such new
                  Notes shall be dated the Initial Borrowing Date and shall
                  otherwise be in the form of the Notes replaced thereby. The
                  Notes surrendered by the transferor Lender shall be returned
                  by the Administrative Agent to the Borrower marked
                  "cancelled."

            (c)   Upon its receipt of an Assignment and Acceptance executed by a
                  transferor Lender and a Purchasing Lender (and, in the case of
                  a Purchasing Lender that is not then a Lender or an affiliate
                  thereof, consented to by the Borrower, the Administrative
                  Agent and the Issuing Bank (if the consent of the Borrower and
                  the Administrative Agent and the Issuing Bank is required))
                  and the Administrative Agent, together with

<PAGE>
                  payment to the Administrative Agent hereunder of a
                  registration and processing fee of $2,500 and to the
                  Administrative Agent (as defined in the Participation
                  Agreement) the registration and processing fee referred to in
                  Section 6.3 of the Participation Agreement (provided, a Lender
                  being replaced pursuant to SECTION 4.15 shall have no
                  obligation to pay such registration and processing fees), the
                  Administrative Agent shall (i) promptly accept such Assignment
                  and Acceptance and (ii) on the Transfer Effective Date
                  determined pursuant thereto give notice of such acceptance and
                  recordation to the Lenders and the Borrower.

            (d)   The provisions of the foregoing CLAUSES (B) and (C) shall not
                  apply to or restrict, or require the consent of or any notice
                  to any Person to effectuate, the pledge or assignment by any
                  Lender of its rights under this Agreement and its Notes to any
                  Federal Reserve Bank.

            (e)   If, pursuant to this SECTION 14.6 any interest in this
                  Agreement or any Note is transferred to any transferee (a
                  "TRANSFEREE") which is organized under the laws of any
                  jurisdiction other than the United States or any State
                  thereof, the transferor Lender shall cause such Transferee,
                  concurrently with the effectiveness of such transfer, (i) to
                  represent to the transferor Lender (for the benefit of the
                  transferor Lender, the Administrative Agent, the Issuing Bank,
                  the Documentation Agent and the Borrower) that under
                  applicable law and treaties no taxes will be required to be
                  withheld by the Administrative Agent, the Borrower or the
                  transferor Lender with respect to any payments to be made to
                  such Transferee in respect of the Loans or Letters of Credit,
                  (ii) to furnish to the transferor Lender (and, in the case of
                  any Purchasing Lender, the Administrative Agent, the Issuing

                  Internal Revenue Service Form 4224 or U.S. Internal Revenue
                  Service Form 1001 (wherein such Transferee claims entitlement
                  to complete exemption from U.S. federal withholding tax on all
                  interest payments hereunder) and (iii) to agree (for the
                  benefit of the transferor Lender, the Administrative Agent,
                  the Issuing Bank, the Documentation Agent and the Borrower) to
                  provide the transferor Lender (and, in the case of any
                  Purchasing Lender, the Administrative Agent, the Issuing Bank,
                  the Documentation Agent and the Borrower) a new Form 4224 or
                  Form 1001 upon the expiration or obsolescence of any
                  previously delivered form and comparable statements in
                  accordance with applicable U.S. laws and regulations and
                  amendments duly executed and completed by such Transferee, and
                  to comply from time to time with all applicable U.S. laws and
                  regulations with regard to such withholding tax exemption.

            (f)   On the Effective Date, the aggregate principal balance of the
                  obligations outstanding under the Original Credit Agreement is
                  $195,780,000 (the

                  Agreement as of the Effective Date are as set forth in the
                  second column of SCHEDULE II. Lenders hereby sell, assign,

                  recourse to the Lenders and without any warranties whatsoever
                  as to title, enforceability, collectibility, documentation or
                  freedom from liens or encumbrances, in whole or in part, other
                  than the warranty by each Lender that it has not sold,
                  transferred, conveyed or encumbered such Interests. If as a
                  result thereof, a Lender's Percentage of the outstanding
                  Borrowings under this Agreement is less than its outstanding
                  loans and letter of credit reimbursement obligations under the
                  Original Credit Agreement on the Effective Date, the
                  difference set forth in the last column of SCHEDULE II shall
                  be remitted to such Lender by the Administrative Agent upon
                  receipt of funds from the other Lenders shown in the last
                  column of SCHEDULE II on the Effective Date. Each Lender so
                  acquiring a part of such outstanding loans and letter of
                  credit reimbursement obligations assumes its Percentage of the
                  outstanding Borrowings, Commitments, rights, titles,
                  interests, privileges, claims, liens, security interests,
                  benefits and obligations under this Agreement and the Security
                  Documents. Lenders are proportionately released from the
                  obligations assumed by Lenders so acquiring such obligations
                  and, to that extent, the Lenders so released shall have no
                  further obligation under the Original Credit Agreement, as
                  amended and restated hereby. The Borrower hereby represents
                  and warrants that it has no defenses, offsets or counterclaims
                  to the Prior Indebtedness or its obligations or rights under
                  the Original Credit Agreement, this Agreement or the Security
                  Documents, including, without limitation, the Interests being
                  assigned pursuant to this SECTION 14.6(F). Any Loans
                  outstanding under the Original Credit Agreement on the
                  Effective Date bearing interest at a Eurodollar Interest Rate
                  (as defined in the Original Credit Agreement) shall be deemed
                  continued as a Loan under this Agreement at such Eurodollar
                  Interest Rate and for the Interest Period with respect thereto
                  under the Original Credit Agreement.

      SECTION 14.7 PAYMENT OF COSTS, EXPENSES AND TAXES. The Borrower agrees to
pay on demand all out-of-pocket costs and expenses of the Administrative Agent,
the Collateral Agent, the Issuing Bank and the Documentation Agent (including,
without limitation, the reasonable fees and out-of-pocket expenses of Messrs.
Mayer, Brown & Platt, and any and all other special counsel for the Agents, and
of local counsel, if any, who may be retained by said special counsel) in
connection with (i) the preparation, negotiation, execution, delivery,
syndication and administration of this Agreement, the Notes, the Guaranties, the
Security Documents, and all other instruments or documents provided for herein
or delivered or to be delivered hereunder or in connection herewith, (ii) the
preparation, negotiation, execution and delivery of any and all amendments,
supplements, renewals, restatements, rearrangements, extensions, substitutions,
or modifications to this Agreement, the Notes, the Guaranties, the Security
Documents, and all other instruments or documents provided for herein or
delivered or to be delivered hereunder or in connection herewith except for
those (excluding the preparation of new Notes) incurred in connection with
SECTION 14.6 unless such sale, assignment, or transfer under SECTION 14.6
results from the exercise of Borrower's rights under SECTION 4.15, and (iii) the
enforcement by the Lenders, the Administrative Agent, the Issuing Bank, the
Collateral Agent and the Documentation Agent of, or the protection of rights
under, this Agreement, the Notes, the Guaranties, the Security Documents, any
such other instruments or documents or any collateral security. The
Administrative Agent, the Collateral Agent, each Lender, the Issuing Bank and
the Documentation Agent agree to the extent feasible, and to the extent a
conflict of interest does not exist in the reasonable opinion of the
Administrative Agent, any Lender, the Collateral Agent, the Issuing Bank, the
Documentation Agent or their counsel, to use the same single counsel (i.e. one
law firm) in connection with the foregoing, to the extent they seek
reimbursement for the expenses thereof from the Borrower. Such requests for
payment shall be accompanied by invoices containing reasonable details. Each
Lender agrees to reimburse each of the Administrative Agent, the Collateral
Agent, the Issuing Bank and the Documentation Agent on demand for such Lender's
PRO RATA share (based upon its respective Percentage) of any such costs or
expenses not paid by the Borrower. In addition, the Borrower agrees to pay, and
to save the Administrative Agent, the Collateral Agent and the Documentation
Agent and the Lenders harmless from all liability for, any stamp or other taxes
which may be payable in connection with the execution or delivery of this
Agreement, the Borrowings hereunder, or the issuance of the Notes, the Letters
of Credit, or of any other instruments or documents provided for herein or
delivered or to be delivered hereunder or in connection herewith. All
obligations provided for in this SECTION 14.7, in the last paragraph of SECTION
2.4.2 and in SECTION 2.6, SECTION 4.9, SECTION 4.10, SECTION 4.12, SECTION 4.14
and SECTION 14.8 shall survive any termination of this Agreement. The
representations and warranties made by the Borrower in this Agreement and in
each other Loan Document shall survive the execution and delivery of this
Agreement and each such other Loan Document.

INDEMNIFIED PARTIES (OTHER THAN EXPENSES OF THE TYPE FOR WHICH THE BORROWER

DIRECTORS, OFFICERS, AGENTS OR EMPLOYEES OR RESULTED FROM SUCH INDEMNIFIED
PARTY'S OWN UNEXCUSED BREACH OF ANY MATERIAL PROVISION OF ANY LOAN DOCUMENT),

INVESTIGATION, LITIGATION OR OTHER PROCEEDING. ALL OBLIGATIONS PROVIDED FOR IN
THIS SECTION 14.8 SHALL SURVIVE ANY TERMINATION OF THIS AGREEMENT, THE PAYMENT
OF THE OBLIGATIONS AND THE ASSIGNMENT OF THE NOTES.

      SECTION 14.9 SUBSIDIARY REFERENCES. The provisions of this Agreement
relating to Subsidiaries shall apply only during such times as the Borrower has

reasonable efforts not to disclose without the prior written consent of the
Borrower (other than to its employees, affiliates, auditors or counsel or to any
other party hereto) any information with respect to the Borrower, any of its

               (As Amended and Restated Effective January 1, 1997)

SECTION 1.  ESTABLISHMENT AND PURPOSE

        1.1 ESTABLISHMENT. Tejas Gas Corporation, a Delaware corporation (the
"Company"), previously established a nonqualified stock option plan for
executive officers of the Company and its subsidiaries, known as the Tejas Gas
Corporation Executive Officers Stock Option Plan, which was amended and restated
effective July 21, 1992 and renamed as the "Tejas Gas Corporation Employee Stock
Option Plan," and was subsequently amended by Amendment dated December 9, 1995
(as so amended, the "Prior Plan") and by further amendment adopted on December
13-14,1996. Effective January 1, 1997, the Prior Plan was amended and restated
in the form of the Plan as set forth herein (the "Plan"). The revisions made by
this amendment and restatement of the Plan shall apply both to outstanding
Options and to Options granted on or after January 1, 1997, except that the
amendments to Section 13.3 below shall apply only to Options granted on or after
January 1, 1997 unless the Optionees holding Options outstanding prior to that
date expressly consent to the amendment of their outstanding Options to reflect
such amendments.

        1.2 PURPOSE. The principal purpose of this Plan is to attract, retain
and motivate executive officers and other employees of the Company and its
subsidiaries and to encourage stock ownership by such employees by providing
them with a means to acquire a proprietary interest or to increase their
proprietary interest in the Company.

SECTION 2.  DEFINITIONS

        selling price per share of the Stock on such national securities
        exchange on the date immediately preceding the date of exercise, as
        reported in THE WALL STREET JOURNAL or, if there shall have been no such
        sale so reported on that date, on the last preceding date on which such
        a sale was so reported, or (ii) if the Stock is not so listed, the
        closing selling price (or, if not so reported, the mean between the
        closing bid and asked price) on the date immediately preceding the date
        of exercise, or, if there are no quotations available for such date, on
        the last preceding date on which such quotations shall be available, as
        reported by the Nasdaq Stock Market, or, if not reported by the Nasdaq

                                        2
<PAGE>
SECTION 3.  ELIGIBILITY AND PARTICIPATION

        3.1 ELIGIBILITY AND PARTICIPATION. The Committee shall determine, within
the limits of the express provisions of the Plan, the Eligible Employees to
whom, and the time or times at which, Options shall be granted under the Plan.
In the event that the Committee designates an Eligible Employee of a Subsidiary
of which less than 50% of the voting power of the capital stock entitled to vote
generally in the election of directors is owned by the Company to receive an
Option grant, management will advise the Committee of the tax consequences to
the Company of any such grant.

SECTION 4.  STOCK SUBJECT TO THE PLAN

        4.1 NUMBER. Subject to Sections 4.2 and 4.3, the total number of shares
of Stock that may be optioned under the Plan consists of shares subject to
outstanding options under the Prior Plan at December 31, 1996, shares reserved
under the Prior Plan at December 31, 1996 and not subject to outstanding
options, and, subject to stockholder approval at the 1997 Annual Meeting, an
additional 950,000 shares. These shares may consist, in whole or in part, of
authorized but unissued Stock or treasury Stock, not reserved for any other
purpose.

        4.2 RESTORATION OF UNPURCHASED STOCK AND STOCK WITHHELD FOR TAX
WITHHOLDING. If an Option expires, is cancelled or terminates for any reason
during the term of this Plan and prior to the exercise thereof in full, the
shares of Stock subject to such Option shall again be available for the grant of
Options thereafter. Any shares of Stock withheld to satisfy tax withholding
requirements under Section 14.1 shall again be available for the grant of
Options thereafter.

        4.3 ADJUSTMENT IN SHARES. Subject to the provisions of Section 13
hereof, in the event of any subdivision or consolidation of outstanding shares
of Stock or declaration of a dividend payable in shares of Stock or capital
reorganization or reclassification or other transaction involving an increase or
reduction in the number of outstanding shares of Stock, then (i) the number of
shares of Stock reserved under this Plan, (ii) the number of shares of Stock
issuable pursuant to each Option under this Plan granted before such
transaction, and (iii) the per share Option Price of previously awarded Options
under this Plan shall be proportionately adjusted to reflect such transaction.
Such adjustment to the number of shares of Stock shall reflect the proportional
adjustment to the number of shares of Stock (or such other capital stock as may
be issued in a reclassification) that a stockholder who owned an equivalent
number of shares immediately before the happening of any of the events described
in the preceding sentence would have owned or been entitled to receive after the
happening of any of such events, and the adjustment to the Option Price of a
previously awarded Option shall be determined by dividing the number of shares
of Stock (or other capital stock) subject to the Option after the adjustment by
the aggregate Option Price for all shares that were subject to the Option
immediately prior to the transaction. Except as otherwise provided in Section
13.1 or 13.2, in the event of any consolidation or merger of the Company with
another corporation or entity or the adoption by the Company of a plan of
exchange affecting the Stock or any distribution to holders of Stock of
securities or property (other than cash dividends or 

                                        3
<PAGE>
dividends payable in Stock), the Committee shall make such adjustments as it may
deem equitable, including adjustments to avoid fractional shares, to give proper
effect to such event; provided that such adjustments shall only be such as are
necessary to maintain the proportionate interest of the Optionees and preserve,
without exceeding, the value of the Options under this Plan. In the event of a
corporate merger, consolidation, acquisition of property or stock, separation,
reorganization or liquidation, the Committee shall be authorized to issue or
assume Options, regardless of whether in a transaction to which Section 424(a)
of the Code applies, by means of substitution of new Options for previously
issued Options or an assumption of previously issued Options.

SECTION 5.  DURATION OF PLAN

        5.1 DURATION OF THE PLAN. The Plan shall remain in effect until all
Stock subject to it shall have been purchased pursuant to the exercise of
Options.

SECTION 6.  OPTIONS

        6.1 GRANT OF OPTIONS. Subject to the provisions of Section 4.1, Options
may be granted to Eligible Employees at any time and from time to time as shall
be determined by the Committee. The Committee shall have complete discretion in
determining the number of Options granted to each Optionee, the number of shares
of Stock subject to such Options, and the Option Price to be paid by the
Optionee with respect to such shares; PROVIDED, HOWEVER, that (a) no Optionee
may be granted, during any calendar year, Options for more than 200,000 shares
of Stock, subject to adjustment in like manner as adjustments to the number of
shares of Stock provided in Section 4.3 hereof, and (b) no Option shall have an
Option Price that is less than the Fair Market Value of the Stock on the date of
grant. In making such determinations, the Committee may take into account the
nature of services rendered by such individuals, their present and potential
contributions to the Company and such other factors as the Committee in its sole
discretion shall deem relevant.

        6.2 OPTION AGREEMENT. As determined by the Committee on the date of
grant, each Option shall be evidenced by a Stock Option agreement ("Option
Agreement") that shall, among other things, specify the Option Price, the
duration of the Option, and the number of shares of Stock to which the Option
pertains. Each Option granted under the Plan on or after January 1, 1997 shall
expire as of the date prescribed in the Option Agreement (which date shall be no
later than ten years after the date of the Option grant), subject to earlier
expiration under the provisions of Section 8. Each Option granted under the Plan
prior to January 1, 1997 shall expire as of the date prescribed in the Option
Agreement (which date shall be no later than seven years after the date of the
Option grant), subject to earlier expiration under the provisions of Section 8.

        6.3 EXERCISE. Except as otherwise provided herein, an Option, after the
grant thereof, shall be exercisable by the Optionee at such rate and times as
may be fixed by the Committee at the time the Option is granted; PROVIDED,
HOWEVER, that an Optionee may exercise any Option in full,

                                        4
<PAGE>
whether or not it is then exercisable, upon the occurrence of such circumstance
or event which, in the sole discretion of the Committee, merits special
consideration.

        6.4 PAYMENT. The Option Price upon exercise of any Option shall be
payable to the Company in full either (i) in cash or its equivalent, (ii) by
tendering shares of previously acquired Stock having a Fair Market Value on the
date of exercise equal to the total Option Price, (iii) upon approval by the
Committee, by surrendering all or part of that or any other Option, valued at
Fair Market Value on the date of exercise, or (iv) by any combination thereof.
The proceeds from such payment shall be added to the general funds of the
Company and shall be used for its corporate purposes.

        6.5 CANCELLATION OF PREVIOUSLY GRANTED OPTIONS. In the event the Fair
Market Value of the Stock is ever less than the Option Price of any outstanding
Option, the Committee has the authority to cancel such Option and issue in its
place a new substitute Option for the same number of shares at a new Option
Price and subject to the terms of the Plan. The granting of a substitute Option
shall be deemed a new Option.

SECTION 7. WRITTEN NOTICE, ISSUANCE OF STOCK CERTIFICATES, STOCKHOLDER
           PRIVILEGES, PARTIAL EXERCISE, AND REGISTRATION.

        7.1 WRITTEN NOTICE. An Optionee wishing to exercise an Option shall give
written notice to the Company, in the form and manner prescribed by the
Committee, indicating the number of shares with respect to which such Option is
to be exercised. Full payment for the shares exercised pursuant to an Option
must accompany the written notice.

        7.2 ISSUANCE OF STOCK CERTIFICATES. As soon as practicable after the
receipt of written notice and payment, the Company shall, without Stock issue or
transfer taxes to the Optionee or to any other person entitled to exercise an
Option pursuant to the Plan, deliver to the Optionee or such other person a
certificate or certificates for the requisite number of shares of Stock.

        7.3 PRIVILEGES OF A STOCKHOLDER. An Optionee or any other person
entitled to exercise an Option under this Plan shall have no rights as a
stockholder with respect to any Stock covered by the Option until the date of
issuance of a certificate for such Stock.

        7.4 PARTIAL EXERCISE. An Option may be exercised as to any lesser number
of shares than the full amount for which it could be exercised. Such a partial
exercise of an Option shall not affect the right to exercise the Option from
time to time in accordance with this Plan as to the remaining shares subject to
the Option.

        7.5 REGISTRATION. The Company shall endeavor, but shall not be
obligated, to register the Stock to be issued upon exercise of all Options under
the Securities Act of 1933, as amended, as well as any applicable state
statutes. In the event that Stock to be issued upon exercise of an 

                                        5
<PAGE>
Option is not so registered, the Company may, as a condition precedent to the
exercise of such Option, require from the Optionee or any transferee under
Section 9.2 (or, in the event of the death of the Optionee or such transferee,
his legal heirs, legatees or distributees) such written representations and
agreements as, in the opinion of counsel for the Company, may be necessary to
ensure that such exercise and subsequent disposition will not involve a
violation of the Securities Act of 1933, as amended, or any other applicable
federal or state statute as then in effect.

SECTION 8.  TERMINATION OF SERVICE

        8.1 DEATH. If an Optionee's service to the Company and its Subsidiaries
terminates by reason of death, the Option shall be exercisable only to the
extent exercisable as of the date of such Optionee's death, unless the Committee
(either prior to or after such Optionee's death) provides that such Option will
become immediately exercisable in full. Such Option shall expire twelve (12)
months after the date of such Optionee's death, or on its stated expiration
date, whichever period is shorter. The Committee may extend the exercise period
beyond twelve (12) months as it deems appropriate (either prior to or after such
Optionee's death), but in no event shall the exercise period exceed the
expiration date of the Option. Options which were not exercisable as of the date
of such termination of service shall be forfeited and no longer subject to any
right to exercise, unless otherwise provided by the Committee.

        8.2 DISABILITY. If an Optionee's service to the Company and its
Subsidiaries terminates by reason of disability (as defined under the federal
Social Security Act of 1935, as amended), the Option shall be exercisable only
to the extent exercisable as of the date of such termination of service and
shall expire three (3) months after the date of such termination, or on its
stated expiration date, whichever period is shorter. Options which were not
exercisable as of the date of such termination of service shall be forfeited and
no longer subject to any right to exercise.

        8.3 RETIREMENT OR INVOLUNTARY TERMINATION. In the event the service of
an Optionee is terminated by reason of normal or early retirement (as defined
under the Company's tax-qualified retirement plan or, where pertinent, any
Subsidiary's retirement plan) or the Employer (whether the Company or a
Subsidiary) shall terminate the Optionee's employment for any reason other than
for "Cause," as defined below ("Involuntary Termination Not For Cause"), the
Option shall be exercisable only to the extent exercisable as of the date of
such retirement or termination and shall expire on the date thirty (30) calendar
days after the date of such retirement or termination, or on its stated
expiration date, whichever shall first occur. Except as otherwise provided
herein, Options which were not exercisable as of the date of such termination of
service shall be forfeited and no longer subject to any right to exercise.
"Cause" shall mean any of the following: (a) conviction of the Optionee by a
court of competent jurisdiction of any felony; (b) the Optionee's knowing
failure or refusal to follow reasonable instructions of the Board or reasonable
policies, standards and regulations of the Company or its Subsidiaries, unless
the Optionee reasonably believed in good faith that such failure or refusal was
in the best interests of the Company; (c) the Optionee's continued failure or
refusal to faithfully and diligently perform the usual, customary duties of his

                                        6
<PAGE>
employment with the Company or Subsidiary; (d) the Optionee's continually
conducting himself in an unprofessional, unethical, immoral or fraudulent
manner; or (e) the Optionee's conduct discredits the Company or Subsidiary or is
detrimental to the reputation, character and standing of the Company or
Subsidiary; provided that, if "cause" is defined in any employment agreement
between the Optionee and the Company or Subsidiary in effect at the time of the
Optionee's termination of employment, "cause" shall have the meaning given such
term in such employment agreement and the foregoing clauses (a) through (e)
shall not apply. "Cause" shall not be deemed to occur by reason of conduct
described in clause (b), (c), (d) or (e) of the preceding sentence unless such
conduct continues for 30 days after the Company has provided written notice to
the Optionee of the conduct that constitutes "Cause."

        8.4 OTHER TERMINATION. If an Optionee's service shall terminate for any
reason other than death, disability, retirement or Involuntary Termination Not
For Cause, any Options which are unexercised as of the date of such termination
shall be forfeited and no longer subject to any right to exercise.

SECTION 9.  RIGHTS OF OPTIONEES

        9.1 EMPLOYMENT. Nothing in this Plan shall interfere with or limit in
any way the right of the Company or any Subsidiary to terminate any Optionee's
service at any time, nor confer upon any Eligible Employee any right to continue
in the employ of the Company or any Subsidiary.

        9.2 TRANSFERABILITY. Except as otherwise provided herein, no Option
granted under this Plan shall be assignable or otherwise transferable by the
Optionee (or his or her authorized legal representative) during the Optionee's
lifetime and, after the death of the Optionee, other than by will or the laws of
descent and distribution; and any attempted assignment or transfer in violation
of this Section 9.2 shall be null and void. Upon the Optionee's death, the
personal representative or other person entitled to succeed to the rights of the
Optionee (the "Successor Optionee") may exercise such rights. A Successor
Optionee must furnish proof satisfactory to the Company of his or her right to
exercise the Option under the Optionee's will or under the applicable laws of
descent and distribution.

            Subject to approval by the Committee in its sole discretion, all or
a portion of the Options granted to an Optionee under the Plan may be
transferable by the Optionee to, to the extent and only to the extent specified
in such approval, (i) the children or grandchildren of the Optionee
("Immediate Family Members"), (ii) a trust or trusts for the exclusive benefit
of such Immediate Family Members ("Immediate Family Member Trusts"), or (iii) a
partnership or partnerships in which such Immediate Family Members have at least
99% of the equity, profit and loss interests ("Immediate Family Member
Partnerships"); provided that the Option Agreement pursuant to which such
Options are granted (or an amendment thereto) must expressly provide for
transferability in a manner consistent with this Section. Subsequent transfers
of transferred Options shall be prohibited except by will or the laws of descent
and distribution, unless such transfers are made to

                                        7
<PAGE>
the original Optionee or a person to whom the original Optionee could have made
a transfer in the manner described herein. No transfer shall be effective unless
and until written notice of such transfer is provided to the Company, in the
form and manner prescribed by the Company. Following transfer, any such Options
shall continue to be subject to the same terms and conditions as were applicable
immediately prior to transfer, and, except as otherwise provided herein, the
term "Optionee" shall be deemed to refer to the transferee. The events of
termination of service in Section 8 shall continue to be applied with respect to
the original Optionee, following which the Options shall be exercisable by the
transferee only to the extent and for the periods specified in Section 8.

SECTION 10.  LEAVE OF ABSENCE

        10.1 LEAVE OF ABSENCE. For Plan purposes a leave of absence, duly
authorized by the Company or any Subsidiary, shall not be deemed a termination
of employment. However, under no circumstances may an Optionee exercise an
Option during any leave of absence, unless authorized by the Committee.

SECTION 11.  ADMINISTRATION

        11.1 ADMINISTRATION. The Committee shall be responsible for the
administration of the Plan. The Committee, by majority action thereof, is
authorized to interpret the Plan, to prescribe, amend, and rescind rules and
regulations relating to the Plan, provide for conditions and assurances deemed
necessary or advisable to protect the interests of the Company and to make all
other determinations necessary or advisable for the administration of the Plan,
but only to the extent not contrary to the express provisions of the Plan. The
determinations of the Committee, interpretations, or other actions made or taken
pursuant to the provisions of the Plan shall be final and shall be binding and
conclusive for all purposes and upon all persons.


SECTION 12.  AMENDMENT, MODIFICATION, AND TERMINATION OF THE PLAN

        12.1 AMENDMENT, MODIFICATION, AND TERMINATION OF THE PLAN. The Board may
at any time terminate, and from time to time may amend or modify the Plan;
PROVIDED, HOWEVER, that no amendment, modification, or termination of the Plan
shall in any manner adversely affect any Option granted under the Plan prior to
such amendment, modification or termination without the consent of the Optionee.

<PAGE>
SECTION 13.  MERGER, CONSOLIDATION OR CHANGE IN CONTROL

        13.1 COMPANY SURVIVING CORPORATION. Subject to any required action by
the stockholders of the Company, if the Company shall be the surviving
corporation in any merger, consolidation or reorganization in which holders of
shares of Stock receive other securities in exchange for their Stock, any Option
granted hereunder shall pertain to and apply to the securities to which a holder
of the number of shares of Stock subject to the Option would have been entitled.

        13.2 COMPANY NOT SURVIVING CORPORATION. If the Company is merged,
consolidated with, or otherwise reorganized with or into another corporation and
the Company is not the surviving corporation, then (i) the Board of Directors of
the Company or the Board of Directors of any corporation assuming the
obligations of the Company under the Plan shall, as to the unexercised portion
of any Option, make appropriate provision for the protection of such Option by
the substitution on an equitable basis of appropriate securities of the Company,
or of the merged, consolidated or otherwise reorganized corporation, which will
be issuable in respect of the unexercised portion of the Option, or (ii)
immediately prior to such merger, consolidation or other reorganization the
unexercised portion of the Option, whether or not exercisable, shall immediately
be exercisable.

        13.3 CHANGE IN CONTROL. If any person, firm or corporation (other than
Frederic C. Hamilton, Charles C. Gates or Jay Precourt or any affiliate (either
directly or through one or more intermediaries) of any of them) shall become the
record or beneficial owner of securities of the Company entitling the owner
thereof to vote more than 50% of all of the votes which may be cast with respect
to matters submitted to a vote of the holders of the Stock, or if all or
substantially all of the assets of the Company are acquired by any person, or if
the Company adopts a plan of liquidation, then all outstanding Options shall
become immediately vested and exercisable, whether or not vested and exercisable
prior thereto.

SECTION 14.  TAX WITHHOLDING

        14.1 TAX WITHHOLDING. If the Company or a Subsidiary shall be required
to withhold any amounts by reason of any federal, state or local tax rules or
regulations in respect of the payment of cash or the issuance of Stock pursuant
to the exercise of an Option, the Company or such Subsidiary shall be entitled
to deduct and withhold such amounts from any cash payments to be made to the
Optionee or from any shares which would otherwise be delivered to the Optionee
upon exercise (which shares shall be valued at Fair Market Value as of the date
of payment of the Option Price by the Optionee). In any event, the Optionee
shall make available to the Company or such Subsidiary, promptly when requested
by the Company or such Subsidiary, sufficient funds to meet the requirements of
such withholding, and the Company or such Subsidiary shall be entitled to take
and authorize such steps as it may deem advisable in order to have such funds
made available to the Company or such Subsidiary out of any funds or property
due or to become due to the Optionee.

                                        9

SECTION 15.  INDEMNIFICATION

        15.1 INDEMNIFICATION. Each person who is or shall have been a member of
the Committee or of the Board shall be indemnified and held harmless by the
Company against and from any loss, cost, liability, or expense that may be
imposed upon or reasonably incurred by him in connection with or resulting from
any claim, action, suit, or proceeding to which he may be a party or in which he
may be involved by reason of any action taken or failure to act under the Plan
and against and from any and all amounts paid by him in settlement thereof, with
the Company's approval, or paid by him in satisfaction of a judgment in any such
action, suit, or proceeding against him, provided he shall give the Company an
opportunity, at its own expense, to handle and defend the same before he
undertakes to handle and defend it on his own behalf. The foregoing right of
indemnification shall not be exclusive of, and is in addition to, any other
rights of indemnification to which any person may be entitled under the
Company's certificate of incorporation or bylaws, as a matter of law, or
otherwise, or any power that the Company may have to indemnify them or hold them
harmless.

SECTION 16.  REQUIREMENTS OF LAW

        16.1 REQUIREMENTS OF LAW. The granting of Options and the issuance of
shares of Stock upon the exercise of an Option shall be subject to all
applicable laws, rules, and regulations, and to such approvals by any
governmental agencies or national securities exchanges as may be required.

        16.2 GOVERNING LAW. The Plan, and all agreements hereunder, shall be
construed in accordance with and governed by the laws of the State of Delaware.

SECTION 17.  EFFECTIVE DATE

        17.1 EFFECTIVE DATE. The Plan was originally adopted effective September
1, 1988 and was approved by a subsidiary of Hamilton Oil Corporation as the sole
stockholder of the Company. The Prior Plan was approved at the 1993 annual
meeting of the stockholders and was amended by the Board in 1995. The Plan, as
amended and restated effective January 1, 1997, shall be effective upon
stockholder approval of the amended and restated Plan at the 1997 annual meeting
of the stockholders. If the amended and restated Plan is not approved at the
1997 annual meeting of the stockholders, then any Options granted hereunder
shall be subject to the terms and conditions of the Prior Plan.

As approved by the
Board of Directors
of the Company on


Secretary

                                                                    EXHIBIT 10.3

                              TEJAS GAS CORPORATION

                           DIRECTOR STOCK OPTION PLAN

               (As Amended and Restated Effective January 1, 1997)

1.      ESTABLISHMENT AND PURPOSE

        Tejas Gas Corporation, a Delaware corporation (the "Company"),
previously established the Tejas Gas Corporation Director Stock Option Plan, a
nonqualified stock option plan for nonemployee directors of the Company,
effective March 13, 1992, as amended by the First Amendment thereto effective
March 13, 1992 and as subsequently amended by Amendment dated December 9, 1995
(the "Prior Plan"). Effective January 1, 1997, the Prior Plan was amended and
restated in the form of the Plan as set forth herein (the "Plan"). The revisions
made by this amendment and restatement of the Plan shall apply both to
outstanding options and options granted on or after January 1, 1997, except that
the amendments to the events triggering accelerated exercisability of the
options under Section 5.E below shall apply only to options granted on or after
January 1, 1997 unless the optionees holding options outstanding prior to that
date expressly consent to the amendment of their outstanding options to reflect
such amendments. The purpose of the Plan is to encourage ownership in the
Company by outside directors of the Company whose services are considered
essential to the Company's continued progress and thus to provide them with a
further incentive to continue to serve as directors of the Company. The Plan is
also intended to assist the Company through utilization of the incentives
provided by the Plan to attract and retain experienced and qualified candidates
to fill vacancies in the Board which may occur in the future.

2.      ADMINISTRATION

        The Plan will be administered by the Board of Directors (the "Board") of
the Company.

        Subject to the express provisions of the Plan, the Board will have
complete authority to interpret the Plan; to prescribe, amend, and rescind rules
and regulations relating to it; to determine the terms and provisions of the
respective option agreements in accordance with the provisions of the Plan; and
to make all other determinations necessary or advisable for the administration
of the Plan. The Board's determination on the matters referred to in this
Section 2 will be conclusive.

3.      PARTICIPATION IN THE PLAN

        The Chairman of the Board and Directors of the Company who are not
employees of the Company or any affiliate of the Company ("Eligible Directors")
shall be eligible to participate in

                                       -1-
<PAGE>
the Plan; provided that the recipient of an option must be serving as an
Eligible Director on the date the option is granted.

4.      STOCK SUBJECT TO THE PLAN

        The stock subject to the Plan shall consist of shares subject to
outstanding options under the Prior Plan at December 31, 1996, and shares
reserved under the Prior Plan at December 31, 1996 and not subject to
outstanding options ("Common Stock"). Such shares may, as the Board shall from
time to time determine, be either authorized and unissued shares of Common Stock
or issued shares of Common Stock which have been reacquired by the Company. If
any option granted under the Plan expires or terminates for any reason without
having been exercised in full, the shares subject to, but not delivered under,
such option may again become available for the grant of other options under the
Plan.

5.      STOCK OPTIONS

        Each option granted under this Plan shall be evidenced by a written
agreement in such form as the Company shall from time to time prescribe, which
agreements shall comply with and be subject to the following terms and
conditions:

        A. OPTION GRANT DATES. The first grant of options under this Plan
        occurred as of March 13, 1992 (the "1992 Options"). An initial grant of
        options under this Plan shall be made to each Eligible Director upon his
        initial appointment or election as an Eligible Director (the "Initial
        Options"). Options shall thereafter be granted annually to each Eligible
        Director automatically on the first business day following the Company's
        Annual Meeting of Stockholders ("Annual Grant Date"), beginning in 1992.

        B. NUMBER OF SHARES. Each Eligible Director serving on the Board at
        January 1, 1997 has been awarded an Initial Option to purchase 24,750
        shares of Common Stock. Any Eligible Director who first becomes a
        Director after January 1, 1997 shall receive an initial grant of Initial
        Options covering 24,750 shares on the first Annual Grant Date after
        first becoming a Director. Annual awards of options to purchase 2,475
        shares of Common Stock have been granted to each Eligible Director on
        the Annual Grant Date. Hereafter, annual awards of options to purchase
        2,475 shares of Common Stock shall be granted to each Eligible Director
        on the Annual Grant Date in each year after the year in which the
        Eligible Director is awarded Initial Options. The number of shares of
        Common Stock subject to the Initial Option and the annual awards has
        been adjusted to reflect stock splits and stock dividends prior to
        January 1, 1997.

        C. OPTION PRICE PER SHARE. The options granted prior to January 1, 1997
        are exercisable at the price established at the time of grant, adjusted
        to reflect stock splits and stock dividends prior to January 1, 1997.
        All other options granted hereunder shall be exercisable at a price per
        share equal to the "Fair Market Value" of the Common Stock

                                       -2-
<PAGE>
        on the date of the grant of the option. For all purposes of this Plan
        OTHER THAN the determination of the exercise price of an option, the
        'Fair Market Value' of a share on a particular date shall be deemed to
        be, (i) if the Common Stock is listed on a national securities exchange,
        the closing selling price per share of the Common Stock on such national
        securities exchange on the date immediately preceding the date of
        exercise, as reported in THE WALL STREET JOURNAL or, if there shall have
        been no such sale so reported on that date, on the last preceding date
        on which such a sale was so reported, or (ii) if the Common Stock is not
        so listed, the closing selling price (or, if not so reported, the mean
        between the closing bid and asked price) on the date immediately
        preceding the date of exercise, or, if there are no quotations available
        for such date, on the last preceding date on which such quotations shall
        be available, as reported by the Nasdaq Stock Market, or, if not
        reported by the Nasdaq Stock Market, by the National Quotation Bureau,
        Inc. For the purpose of determining the exercise price of an option
        granted hereunder, however, the Fair Market Value shall be deemed to be
        such closing selling price per share of the Common Stock as described
        above, but determined as of the date of grant of the Option.

        D. TRANSFERABILITY OF OPTIONS. Except as otherwise provided herein, no
        option granted under this Plan shall be assignable or otherwise
        transferable by the optionee (or his or her authorized legal
        representative) during the optionee's lifetime and, after the death of
        the optionee, other than by will or the laws of descent and
        distribution; and any attempted assignment or transfer in violation of
        this Section 5.D shall be null and void. Upon the optionee's death, the
        personal representative or other person entitled to succeed to the
        rights of the optionee (the "Successor Optionee") may exercise such
        rights. A Successor Optionee must furnish proof satisfactory to the
        Company of his or her right to exercise the option under the optionee's
        will or under the applicable laws of descent and distribution. Any
        option granted under the Plan by its terms may be transferable by the
        optionee to (i) the children or grandchildren of the optionee
        ("Immediate Family Members"), (ii) a trust or trusts for the exclusive
        benefit of such Immediate Family Members ("Immediate Family Member
        Trusts"), or (iii) a partnership or partnerships in which such Immediate
        Family Members have at least 99% of the equity, profit and loss
        interests ("Immediate Family Member Partnerships"); provided that the
        stock option agreement pursuant to which such options are granted (or an
        amendment thereto) must expressly provide for transferability in a
        manner consistent with this paragraph D. Subsequent transfers of
        transferred options shall be prohibited except by will or the laws of
        descent and distribution, unless such transfers are made to the original
        optionee or a person to whom the original optionee could have made a
        transfer in the manner described herein. No transfer shall be effective
        unless and until written notice of such transfer is provided to the
        Company at its corporate office. Following transfer, any such options
        shall continue to be subject to the same terms and conditions as were
        applicable immediately prior to transfer, and, except as otherwise
        provided herein, the term "optionee" shall be deemed to refer to the
        transferee. The events of termination of service on the Board in
        paragraphs F and G hereof shall continue to be applied with respect to
        the original optionee, following which the options shall be exercisable
        by the transferee only to the extent and for the periods specified in
        paragraphs F and G.

                                       -3-
<PAGE>
        E. EXERCISABILITY AND TERM OF OPTIONS. Except for the 1992 Options
        (which are fully vested), each option granted under this Plan shall
        become exercisable, on a cumulative basis, in five equal installments,
        with the first installment becoming exercisable six months after the
        date of grant, and the remaining four installments becoming exercisable
        annually commencing on the first anniversary of the date of grant. Each
        option granted under the Plan on or after January 1, 1997 shall expire
        ten years from the date of the grant and shall be subject to earlier
        expiration as herein provided. Each option granted prior to January 1,
        1997 shall expire seven years from the date of the grant and shall be
        subject to earlier expiration as herein provided. Notwithstanding the
        foregoing, if (a) the Company shall execute a definitive agreement to
        merge or consolidate with or into another corporation and the Company
        shall not be the surviving corporation in the merger (or shall become a
        subsidiary of any other corporation party to such agreement) and the
        stockholders of the Company shall have approved the terms of such
        agreement; (b) the Company shall enter into a definitive agreement to
        sell or otherwise dispose of all or substantially all of its assets to
        any person, firm or corporation, and the stockholders of the Company
        shall have approved the terms of such agreement; or (c) any person or
        group, other than Frederic C. Hamilton, Charles C. Gates or Jay Precourt
        (or any affiliate (either directly or through one or more
        intermediaries) of any of them) shall become the record or beneficial
        owner of securities of the Company entitling the owner thereof to vote
        more than 50% of all of the votes which may be cast with respect to
        matters submitted to a vote of the holders of the Common Stock, then, in
        any of such events described in clauses (a), (b) or (c) preceding, all
        outstanding options shall become immediately vested and exercisable,
        whether or not vested and exercisable prior thereto.

        F.     TERMINATION OF SERVICE.

               1. OPTIONS GRANTED PRIOR TO JANUARY 1, 1997. In the event of the
               termination of service on the Board by the holder of any option,
               other than by reason of retirement, total and permanent
               disability or death as set forth in paragraph G. hereof, the then
               outstanding options of such holder granted prior to January 1,
               1997 may be exercised only to the extent that they were
               exercisable on the date of such termination and shall expire on
               the date three months after such termination, or on their stated
               expiration date, whichever occurs first. For purposes of this
               Plan, the term "by reason of retirement" shall mean mandatory
               retirement pursuant to Board policy.

               2. OPTIONS GRANTED ON OR AFTER JANUARY 1, 1997. In the event of
               the termination of service on the Board by the holder of any
               option, other than (i) by reason of retirement (as defined
               above), (ii) by the Company for any reason other than for cause
               ("Involuntary Termination Not For Cause"), or (iii) by reason of
               total and permanent disability or death as set forth in paragraph
               G. hereof, any options of such holder granted on or after January
               1,

                                       -4-
<PAGE>
               1997 and unexercised as of the date of such termination shall be
               forfeited and no longer subject to any right to exercise.

        G.     RETIREMENT, INVOLUNTARY TERMINATION, DISABILITY OR DEATH.

               1 OPTIONS GRANTED PRIOR TO JANUARY 1, 1997. In the event of
               termination of service by reason of retirement (as defined above)
               or the total and permanent disability of the holder of any
               option, each of the then outstanding options of such holder
               granted prior to January 1, 1997 will continue to vest and become
               exercisable during such five year period according to the
               original vesting schedule set forth in the option agreement and
               the holder may exercise the vested installments at any time
               within five years after such retirement or disability but in no
               event after the stated expiration date of the term of the option.
               In the event of the death of the holder of any option, each of
               the then outstanding options of such holder granted prior to
               January 1, 1997 will immediately vest in full and become
               exercisable by the holder's legal representative at any time
               within a period of five years after death, but in no event shall
               the option be exercised (i) after the stated expiration date of
               the term of the option or (ii) less than six months after the
               option was granted. However, if the holder dies within five years
               following termination of service on the Board by reason of
               retirement or total and permanent disability, any option granted
               prior to January 1, 1997 shall only be exercisable for two years
               after the holder's death or five years after retirement or
               termination for total and permanent disability; whichever is
               longer, or until the stated expiration date of the term of the
               option, if earlier.

               2. OPTIONS GRANTED ON OR AFTER JANUARY 1, 1997. In the event of
               termination of service by reason of retirement (as defined above)
               or Involuntary Termination Not For Cause, each of the then
               outstanding options of such holder granted on or after January 1,
               1997 will be exercisable only to the extent exercisable as of the
               date of such retirement or termination and shall expire on the
               date thirty (30) calendar days after the date of such retirement
               or termination, or on its stated expiration date, whichever shall
               first occur. In the event of termination of service by reason of
               the total and permanent disability of the holder, each of the
               then outstanding options of such holder granted on or after
               January 1, 1997 will be exercisable only to the extent
               exercisable as of the date of such termination of service and
               shall expire on the date three months after the date of such
               termination, or on its stated expiration date, whichever shall
               first occur. In the event of the death of the holder of any
               option, each of the then outstanding options of such holder
               granted on or after January 1, 1997 shall be exercisable only to
               the extent exercisable as of the date of such holder's death and
               shall expire twelve months after the date of such holder's death,
               or on its stated expiration date, whichever period is shorter.

               H. EXERCISE OF OPTIONS. Options may be exercised only by written
               notice to the Company at its corporate office accompanied by
               payment of the full consideration for the shares as to which they
               are exercised, including any federal, state and/or local income
               tax withholding amount due in connection with the exercise. The
               purchase price, together with any income tax withholding amount
               due, is to be paid in full to the Company upon the exercise of
               the option (i) by cash including a personal check payable to the
               order of the Company, (ii) by delivering Common Stock previously
               held by the optionee for at least six months, valued at Fair
               Market Value as of the date of delivery, (iii) by surrendering
               all or part of that or any other option, valued at Fair Market
               Value as of the date of delivery, or (iv) by any combination
               thereof. Shares which otherwise would be delivered to the holder
               of an option upon exercise may, at the election of the optionee,
               be retained by the Company in payment of any federal, state,
               and/or local income tax withholding due in connection with the
               exercise, and shall be valued at Fair Market Value as of the date
               of payment of the option exercise price by the optionee;
               provided, however, that the payment of any amount of withholding
               tax by an optionee with shares of Common Stock (whether already
               owned by the optionee or retained by the Company from the number
               of shares otherwise deliverable to the optionee upon exercise)
               shall be subject to the restrictions set forth in the individual
               option agreements.

               I. NONSTATUTORY OPTIONS. All options granted hereunder shall be
               non-statutory options not intended to qualify under Section 422
               of the Internal Revenue Code of 1986, as amended (the "Code").

6.      ASSIGNMENT

        Except as provided in Section 5.D above, the rights and benefits of a
participant under this Plan may not be assigned and any attempted assignment of
such rights and benefits shall be null and void.

7.      LIMITATION OF RIGHTS

        A. NO RIGHT TO CONTINUE AS A DIRECTOR. Neither the Plan, nor the
        granting of an option nor any other action taken pursuant to the Plan,
        shall constitute or be evidence of any agreement or understanding,
        express or implied, that the Company will retain a Director for any
        period of time, or at any particular rate of compensation.

        B. NO STOCKHOLDER'S RIGHTS FOR OPTIONEES. An optionee or the optionee's
        representative shall have no rights as a stockholder with respect to the
        shares covered by the options until the date of the issuance to the
        optionee or the optionee's representative of a stock certificate
        therefore, and no adjustment will be made for dividends or other rights
        for which the record date is prior to the date such certificate is
        issued.

<PAGE>
8.      CHANGES IN PRESENT STOCK

        A. CORPORATE ACTS. The existence of outstanding options shall not affect
        in any manner the right or power of the Company or its stockholders to
        make or authorize any or all adjustments, recapitalizations,
        reorganizations or other changes in the capital stock of the Company or
        its business or any merger or consolidation of the Company, or any issue
        of bonds, debentures, preferred or prior preference stock (whether or
        not such issue is prior to, on a parity with or junior to the Common
        Stock) or the dissolution or liquidation of the Company, or any sale or
        transfer of all or any part of its assets or business, or any other
        corporate act or proceeding of any kind, whether or not of a character
        similar to that of the acts or proceedings enumerated above.

        B. ADJUSTMENTS. In the event of any subdivision or consolidation of
        outstanding shares of Common Stock or declaration of a dividend payable
        in shares of Common Stock or capital reorganization or reclassification
        or other transaction involving an increase or reduction in the number of
        outstanding shares of Common Stock, then (i) the number of shares of
        Common Stock reserved under this Plan, (ii) the number of shares of
        Common Stock issuable pursuant to each option under this Plan granted
        before such transaction, (iii) the number of shares of Common Stock
        issuable pursuant to each option under this Plan granted after such
        transaction, and (iv) the per share exercise price of previously awarded
        options under this Plan shall be proportionately adjusted to reflect
        such transaction. Such adjustment to the number of shares of Common
        Stock shall reflect the proportional adjustment to the number of shares
        of Common Stock (or such other capital stock as may be issued in a
        reclassification) that a stockholder who owned an equivalent number of
        shares immediately before the happening of any of the events described
        in the preceding sentence would have owned or been entitled to receive
        after the happening of any of such events, and the adjustment to the
        exercise price of a previously awarded option shall be determined by
        dividing the number of shares of Common Stock (or other capital stock)
        subject to the option after the adjustment by the aggregate exercise
        price for all shares that were subject to the option immediately prior
        to the transaction. In the event of any consolidation or merger of the
        Company with another corporation or entity or the adoption by the
        Company of a plan of exchange affecting the Common Stock or any
        distribution to holders of Common Stock of securities or property (other
        than cash dividends or dividends payable in Common Stock), the Board
        shall make such adjustments as it may deem equitable, including
        adjustments to avoid fractional shares, to give proper effect to such
        event; provided that such adjustments shall only be such as are
        necessary to maintain the proportionate interest of the optionees and
        preserve, without exceeding, the value of the options under this Plan.
        In the event of a corporate merger, consolidation, acquisition of
        property or stock, separation, reorganization or liquidation, the Board
        shall be authorized to issue or assume stock options, regardless of
        whether in a transaction to which Section 424(a) of the Code applies, by
        means of substitution of new options for previously issued options or an
        assumption of previously issued options.

9.      EFFECTIVE DATE AND DURATION OF THE PLAN

        The Prior Plan, as originally adopted effective March 13, 1992, was
approved at the 1992 annual meeting of the stockholders. The Plan, as amended
and restated effective January 1, 1997, shall be effective upon stockholder
approval of the amended and restated Plan at the 1997 annual meeting of the
stockholders. If the amended and restated Plan is not approved at the 1997
annual meeting of the stockholders, then any options granted hereunder shall be
subject to the terms and conditions of the Prior Plan. The Plan shall terminate
when all Common Stock subject to the Plan is subject to an option to purchase
(unless earlier discontinued by the Board) but such termination shall not affect
the rights of the holder of any option outstanding on such date of termination.
If, on a date on which options would normally be granted, there is not a
sufficient number of shares available to grant each person otherwise eligible to
receive an option on that date an option to purchase the full number of shares
to which he or she would normally be entitled, options shall be prorated among
optionees according to the number of shares available on such date of grant.
Such optionees shall be deemed to have received the full amount due to them on
such date of grant.

10.     AMENDMENT, MODIFICATION, AND TERMINATION OF THE PLAN

        The Board may at any time terminate, and from time to time may amend or
modify the Plan; PROVIDED, HOWEVER, that no amendment, modification or
termination of the Plan shall in any manner adversely affect any option granted
under the Plan prior to such amendment, modification or termination without the
consent of the optionee.

11.     REQUIREMENTS OF LAW

        The granting of options and the issuance of shares of Common Stock upon
the exercise of an option shall be subject to all applicable laws, rules and
regulations and to such approvals by any governmental agencies or national
securities exchanges as may be required.

12.     NOTICE

        Any written notice to the Company required by any of the provisions of
this Plan shall be addressed to the Secretary of the Company and shall become
effective when it is received.

As approved by the
Board of Directors

Secretary

                                                                   EXHIBIT 10.15

                              TEJAS GAS CORPORATION

                              ANNUAL INCENTIVE PLAN

1.      PURPOSE

        The Annual Incentive Plan (the "Plan") is designed to recognize,
motivate and reward exceptional accomplishment toward annual corporate
objectives; to attract and retain quality employees; and to be market
competitive.

2.      ELIGIBILITY

        All regular full-time and regular part-time employees ("Employees") of
Tejas Gas Corporation (the "Company") and its subsidiaries are eligible to
receive awards under the Plan.

3.      ADMINISTRATION

        As to Employees other than Designated Covered Employees (as defined in
Section 5 below), the Plan shall be administered by the Compensation Committee
of the Board of Directors of the Company (the "Committee"), which shall have the
sole discretion to interpret the Plan, approve preestablished objective
performance measures annually, determine the level to which the performance
measures were attained prior to any payment under the Plan, approve the amount
of awards made under the Plan, and determine who shall receive any payment under
the Plan. As to Designated Covered Employees, the Plan shall be administered by
the Subcommittee (as defined in Section 5 below), which shall have the sole
discretion to interpret the Plan, approve preestablished objective performance
measures annually, certify the level to which the performance measures were
attained prior to any payment under the Plan, approve the amount of awards made
under the Plan, and determine who shall receive any payment under the Plan. The
Committee may delegate authority to officers of the Company to approve the
amount of awards made under the Plan to Employees who are not Designated Covered
Employees. Except for the matters reserved for determination by the Subcommittee
(which are subject to Committee ratification), all decisions and determinations
of the Committee on all matters relating to the Plan shall be conclusive. All
decisions and determinations of the Subcommittee on all matters relating to
Designated Covered Employees under the Plan shall be conclusive upon
ratification by the Committee. Members of the Committee and the Subcommittee
shall not be liable for any action taken or decision made in good faith relating
to the Plan or any award thereunder. Except as provided in this section, only
the Committee shall determine which Employees (other than Designated Covered
Employees) shall receive an award under the Plan and make decisions concerning
the timing, value and amount of any award granted to Employees (other than
Designated Covered Employees) under the Plan. Except as provided in this
section, only the Subcommittee shall determine which Designated Covered
Employees shall receive an award under the Plan and make decisions concerning
the timing, value and amount of any award granted to Designated Covered
Employees under the Plan.

4.      INDIVIDUAL PERFORMANCE AWARD LEVELS

        Not later than 90 days (the "Establishment Date") after the commencement
of the Plan year (calendar year), individual award levels shall be established,
expressed as specified levels of (i)
<PAGE>
earnings per share before deduction of awards made under the Plan and related
income taxes ("EPS") and (ii) earnings before deduction of awards made under the
Plan, interest, income taxes, depreciation, amortization and, if and to the
extent determined by the Committee (as to Employees other than Designated
Covered Employees) or the Subcommittee (as to Designated Covered Employees),
other financing related expenses ("EBITDA"). Each performance measure will be
weighted as determined by the Committee (as to Employees other than Designated
Covered Employees) or the Subcommittee (as to Designated Covered Employees).
Generally, each performance measure reflects an increase in the Company's actual
performance from the previous Plan year. Three performance award levels will be
established based upon Company performance ("threshold," "target" and "stretch"
goals). Employees will be eligible to receive cash payments based upon a
percentage of base salary if the Company meets the "threshold" performance
levels, with payments increasing (as a percentage of base salary) if the
"threshold" performance level is exceeded or the "target" or "stretch"
performance levels are met or exceeded. For each Plan year, the Subcommittee
will determine which Designated Covered Employees will receive payments under
the Plan and will establish the performance award levels and the percentages of
salary for such individuals not later than the Establishment Date of such Plan
year. For each Plan year, the Committee will determine which Employees (other
than Designated Covered Employees) will receive payments under the Plan and will
establish the performance award levels and the percentages of salary for such
individuals not later than the Establishment Date of such Plan year. No Employee
may receive more than a maximum of $1.5 million under the Plan with respect to
attainment of performance levels during any Plan year.

        The establishment of an individual performance criteria for any Employee
shall not give any Employee the right to receive any payment under this Plan.

5.      PAYMENT OF AWARDS

        Prior to authorizing any payments to Designated Covered Employees under
the Plan, approved written minutes shall be recorded of the Subcommittee meeting
in which certification by the Subcommittee is made that the performance goals
and any other material terms of the Plan were satisfied. The "Subcommittee"
shall be a committee of the Board of Directors comprised of members of the
Committee, who qualify as "outside" Directors within the meaning of Section
162(m) of the Internal Revenue Code, as amended, and the regulations thereunder
("Section 162(m)").

        "Designated Covered Employees" shall be those one or more Employees who
are designated as such by the Subcommittee not later than the Establishment Date
of the Plan year. Generally, the Subcommittee will endeavor to designate as
"Designated Covered Employees" for a Plan year those Employees whose (i) awards
under the Plan (when combined with base salary and other non-performance based
compensation) may reasonably be foreseen to exceed the threshold for
nondeductibility by the Company under Section 162(m) and (ii) who would be
"covered employees" under Section 162(m). For Designated Covered Employees,
downward adjustment of the actual award level from the performance award level
may be made at the sole discretion of the Subcommittee. Discretionary upward
adjustment of the actual award level above the performance award level shall not
be allowed for Designated Covered Employees.

                                        2
<PAGE>
        For Employees other than Designated Covered Employees, actual individual
award levels may be adjusted upward or downward at the sole discretion of the
Committee based on an Employee's individual performance.

        Payments made under this Plan may be made in cash or common stock of the
Company (with an equivalent fair market value on the date of payment) as
determined by the Committee (as to Employees other than Designated Covered
Employees) and the Subcommittee (as to Designated Covered Employees). Cash
payments made under this Plan may be deferred by Employees according to the
terms of the Tejas Gas Corporation Thrift Benefit Restoration Plan and the Tejas
Gas Corporation Thrift Plan. The Committee (as to Employees other than
Designated Covered Employees) and the Subcommittee (as to Designated Covered
Employees) will determine the timing of payments under the Plan and may elect to
make payments over more than one calendar year. There will be no increase in the
amount of payment to Employees (other than Designated Covered Employees) as a
result of any award being paid in installments, except that the Committee (as to
Employees other than Designated Covered Employees) may, in its sole discretion,
increase such payments by an amount based on a rate of interest that the
Committee shall determine is reasonable or the actual rate of return of a
specific investment selected by the Committee. There will be no increase in the
amount of payment to Designated Covered Employees as a result of any award being
paid in installments, except that the Subcommittee may, in its sole discretion,
increase such payments by an amount based on a rate of interest that the
Subcommittee shall determine is reasonable or the actual rate of return of a
specific investment selected by the Subcommittee.

6.      UNFUNDED NATURE OF PLAN

        This Plan shall constitute an unfunded mechanism for the Company to pay
incentive compensation to Employees from its general assets. No fund or trust is
created with respect to the Plan, and no Employee shall have any security or
other interest in the assets of the Company.

7.      PROHIBITION AGAINST ASSIGNMENT OR ENCUMBRANCE

        No right, title, interest or benefit hereunder shall ever be liable for
or charged with any of the torts or obligations of an Employee, or be subject to
seizure by any creditor or an Employee or any person claiming under an Employee.
No Employee nor any person claiming under an Employee shall have the power to
sell, transfer, pledge, anticipate or dispose of any right, title, interest or
benefit hereunder in any manner until the same shall have been actually
distributed free and clear of the terms of the Plan.

8.      PLAN NOT AN EMPLOYMENT CONTRACT

        The Plan does not give any Employee the right to be continued in
employment, and all Employees remain subject to change of salary, transfer,
change of job, discipline, layoff, discharge or any other change of employment
status.

                                        3
<PAGE>
9.      SEVERABILITY

        In the event any provision of the Plan shall be held invalid or illegal
for any reason, any illegality or invalidity shall not affect the remaining
parts of the Plan, but the Plan shall be construed and enforced as if the
illegal or invalid provision had never been inserted, and the Company shall have
the privilege and opportunity to correct and remedy such questions of illegality
or invalidity by amendment as provided in the Plan.

10.     WITHHOLDING OF TAXES

        The Company shall have the right to deduct from any payment made under
the Plan any federal, state or local taxes required by law to be withheld with
respect to such awards.

11.     APPLICABLE LAW

        The Plan shall be governed and construed in accordance with the laws of
the State of Texas, except to the extent such laws are preempted by an
applicable federal law.

12.     EFFECTIVE DATE OF PLAN

        The Plan shall be considered effective as of January 1, 1997. If the
Plan is not approved by the stockholders, the Plan will be effective only as to
employees who are not "covered employees" under Section 162(m).

13.     AMENDMENT AND TERMINATION OF THE PLAN

        The Committee (as to Employees other than Designated Covered Employees)
and the Subcommittee (as to Designated Covered Employees) may modify or
terminate the Plan at any time without prior notice to or consent of Employees;
provided that, without the approval of the stockholders of the Company, no such
amendment shall be made that would change the class of Employees eligible to
receive awards under the Plan, base the award on a performance measure other
than EPS and EBITDA, or increase the maximum individual award payment under the
Plan.

      II. Reallocation of Commitments. On the Amendment Effective Date
(hereinafter defined), the aggregate principal balance of the obligations
outstanding under the Credit Agreement is $0 (the "Prior Indebtedness") as shown
on Schedule II hereto, and Borrower represents for itself, and each Lender
represents and warrants for itself, that the Borrower's outstanding loans and
letter of credit reimbursement obligations, if any, under the Credit Agreement
as of the Amendment Effective Date are $0. Lenders hereby sell, assign, transfer
and convey, and Lenders (including, without limitation, those Lenders not
previously a party to the Credit Agreement) hereby purchase and accept so much
of the Prior Indebtedness and all of the rights, titles, benefits, interests,
privileges, claims, liens, security interests, and obligations existing and to
exist (collectively the "Interests") such that each Lender's Percentage of the
outstanding Loans and Commitments under the Credit Agreement as amended by this
First Amendment shall be as set forth in Schedule II hereto as of the Amendment
Effective Date. The foregoing assignment, transfer and conveyance are without
recourse to the Lenders and without any warranties whatsoever as to title,
enforceability, collectibility, documentation or freedom from liens or
encumbrances, in whole or in part, other than the warranty by each Lender that
it has not sold, transferred, conveyed or encumbered such Interests. If as a
result thereof, a Lender's Percentage of the outstanding Borrowings under the
Credit Agreement as amended by this First Amendment is less than its outstanding
loans and letter of credit reimbursement obligations under the Credit Agreement
on the Amendment Effective Date, the difference set forth in the last column of
Schedule II shall be remitted to such Lender by the Administrative Agent upon
receipt of funds from the other Lenders shown in the last column of Schedule II
on the Amendment Effective Date. Each Lender so acquiring a part of such
outstanding loans and letter of credit reimbursement obligations assumes its
Percentage of the outstanding Borrowings, Commitments, rights, titles,
interests, privileges, claims, liens, security interests, benefits and
obligations under the Credit Agreement as amended by this First Amendment and
the Security Documents and the Intercreditor Agreement. Lenders are
proportionately released from the obligations assumed by Lenders so acquiring
such obligations and, to that extent, the Lenders so released shall have no
further obligation under the Credit Agreement as amended by this First Amendment
and the Intercreditor Agreement. The Borrower hereby represents and warrants
that it has no defenses, offsets or counterclaims to the Prior Indebtedness or
its obligations or rights under

                                      5
<PAGE>
the Credit Agreement, this First Amendment or the Security Documents, including,
without limitation, the Interests being assigned pursuant to this Section II.
Each Lender confirms that it has received a copy of the Bank/Exxon Agreement and
represents, warrants and agrees that it has acquired its Interests subject in
all respects to the terms and provisions of the Bank/Exxon Agreement. Any Loans
outstanding under the Credit Agreement on the Amendment Effective Date bearing
interest at a Eurodollar Interest Rate shall be deemed continued as a Loan under
the Credit Agreement as amended by this First Amendment at such Eurodollar
Interest Rate and for the Interest Period with respect thereto under the Credit
Agreement.

      III. Effectiveness. The effectiveness of this First Amendment is
conditioned upon (a) receipt by the Administrative Agent of the following, each
duly executed and each (except for the Notes of which only one original shall be
signed for each Lender) in sufficient number of signed counterparts to provide
one for each Co-Agent and each Lender (except for the Notes of which only one

      signatures and incumbency of officers of the Borrower and each Guarantor
      and a certified copy of the resolutions with respect to the transactions
      contemplated herein;

            (iii) (for delivery to the Borrower) those existing Notes of the
      Borrower in favor of those Lenders whose Original Designated Maximum
      Commitments have increased, decreased or terminated as shown on Schedule
      II, marked "exchanged" or, in the case of a financial institution that
      will no longer be a Lender, marked "cancelled";

            (iv) (for delivery to each Lender whose Original Designated Maximum
      Commitment has increased or decreased) new Notes, duly executed by the
      Borrower, substantially in the form of Exhibit A to the Credit Agreement,
      dated the Amendment Effective Date and with other appropriate insertions
      as to payee and principal amount, payable to the order of each such
      Lender, respectively, in a maximum principal amount equal to such Lender's
      Original Designated Maximum Commitment, as amended hereby; and

            (v) such other documents as any Co-Agent or any Lender may
      reasonably request;

and (b) satisfaction of the condition precedent that the purchase of and payment
for the A-Notes and the B-Notes so as to reallocate the commitments under the
Participation Agreement of the financial institutions party thereto shall have

            Eurodollar Interest Rate shall be determined on the basis of each
            quotation furnished by those of the Reference Lenders which so
            notify the Administrative Agent at or prior to said 11:00 a.m.

                  RSN - shall mean one or more revolving subordinated promissory

            determination thereof is to be made, (i) at a time when the Borrower

interests, privileges, claims, liens, security interests, and obligations
existing and to exist (collectively the "INTERESTS") such that each Lender's
Percentage of the outstanding Loans and Commitments under the Credit Agreement
as amended by this First Amendment shall be as set forth in SCHEDULE II hereto
as of the Amendment Effective Date. The foregoing assignment, transfer and
conveyance are without recourse to the Lenders and without any warranties
whatsoever as to title, enforceability, collectibility, documentation or freedom

benefits and obligations under the Credit Agreement as amended by this First

Credit Agreement as amended by this First Amendment and the Intercreditor
Agreement. The Borrower hereby represents and warrants that it has no defenses,
offsets or counterclaims to the Prior Indebtedness or its obligations or rights
under the Credit Agreement, this First Amendment or the Security Documents,
including, without limitation, the Interests being assigned pursuant to this
SECTION II. Each Lender confirms that it has received a copy of the Bank/Exxon
Agreement and represents, warrants and agrees that it has acquired its Interests
subject in all respects to the terms and provisions of the Bank/Exxon Agreement.

Loan under the Credit Agreement as amended by this First Amendment at such
Eurodollar Interest Rate and for the Interest Period with respect thereto under
the Credit Agreement.
