<PAGE>
                                                                               6

         principal amount to the principal amount of the Transfer Restricted
         Securities surrendered by such Holder.

         The Company and the Guarantor shall use their reasonable best efforts
to complete the Exchange Offer as provided above and shall comply with the
applicable requirements of the Securities Act, the Exchange Act and other
applicable laws and regulations in connection with the Exchange Offer. The

         (b) If (i) because of any change in law or applicable interpretations

Offer as contemplated by Section 2(a) hereof, or (ii) for any other reason the

(iii) within 30 days after consummation of the Exchange Offer, any Initial
Purchaser so requests with respect to Securities not eligible to be exchanged
for Exchange Securities in the Exchange Offer and held by it following the
consummation of the Exchange Offer, or (vi) any applicable law or
interpretations do not permit any Holder to participate in the Exchange Offer,
or any Holder that participates in the Exchange Offer does not receive freely

either case, requests within 30 days after consummation of the Exchange Offer,
the Company and the Guarantor shall use their reasonable best efforts to file as
promptly as practicable (but in no event more than 45 days after so required or
requested pursuant to this Section 2 or 90 days after the Closing Date,
whichever is later) with the SEC (the "Shelf Filing Date"), and thereafter shall
use their reasonable best efforts to cause to be declared effective, a Shelf
Registration Statement on an appropriate form under the Securities Act relating
to the offer and sale of the Transfer Restricted Securities by the Holders
thereof from time to time in accordance with the methods of distribution set
forth in such Shelf Registration Statement.

         In the event that the Company and the Guarantor are required to file a
Shelf Registration Statement pursuant to clause (iii) of the preceding sentence,
the Company and the Guarantor shall use their reasonable best efforts to file
and have declared effective by the SEC both an Exchange Offer Registration
Statement pursuant to Section 2(a) with respect to all Transfer Restricted
Securities and a Shelf Registration Statement (which may be a combined
Registration Statement with the Exchange Offer Registration Statement) with
respect to offers and sales of Transfer Restricted Securities held by the
Initial Purchasers after completion of the Exchange Offer.

<PAGE>
                                                                               7

         The Company and the Guarantor agree to use their reasonable best
efforts to keep the Shelf Registration Statement continuously effective until
the expiration of the period referred to in Rule 144(k) under the Securities Act
with respect to the Transfer Restricted Securities or such shorter period that
will terminate when all the Transfer Restricted Securities covered by the Shelf
Registration Statement have been sold pursuant to the Shelf Registration
Statement (the "Shelf Effectiveness Period"). The Company and the Guarantor
further agree to supplement or amend the Shelf Registration Statement and the
related Prospectus if required by the rules, regulations or instructions
applicable to the registration form used by the Company for such Shelf
Registration Statement or by the Securities Act or by any other rules and
regulations thereunder for shelf registration or if reasonably requested by a
Holder of Transfer Restricted Securities with respect to information relating to
such Holder, and to use their reasonable best efforts to cause any such
amendment to become effective and such Shelf Registration Statement and
Prospectus to become usable as soon as thereafter practicable. The Company and
the Guarantor agree to furnish to the Holders of Transfer Restricted Securities
copies of any such supplement or amendment promptly after its being used or
filed with the SEC.

         (c) The Company and the Guarantor shall pay all Registration Expenses
in connection with the registration pursuant to Section 2(a) and Section 2(b)
hereof. Each Holder shall pay all underwriting discounts and commissions and
transfer taxes, if any, relating to the sale or disposition of such Holder's
Transfer Restricted Securities pursuant to the Shelf Registration Statement.

         (d) An Exchange Offer Registration Statement pursuant to Section 2(a)
hereof or a Shelf Registration Statement pursuant to Section 2(b) hereof will
not be deemed to have become effective unless it has been declared effective by
the SEC.

         In the event that (i) the Exchange Offer Registration Statement is not
filed with the SEC on or prior to 90 days after the Closing Date or the Shelf
Registration Statement is not filed with the SEC on or before the Shelf Filing
Date, (ii) the Exchange Offer Registration Statement is not declared effective
within 180 days after the Closing Date, or the Shelf Registration Statement is
not declared effective within 90 days after the Shelf Filing Date, (iii) the
Exchange Offer is not consummated on or prior to 220 days after the Closing
Date, or (iv) the Shelf Registration Statement is filed and declared effective
by the date required but shall thereafter cease to be effective (at any time
that the Company and the Guarantor are obligated to maintain the effectiveness
thereof) or the Prospectus contained therein ceases to be usable and such
failure to remain effective or be usable exists for more than 30 days (whether
or not successive) within any 12-month period (each such event referred to in
clauses (i) through (iv), a "Registration Default"), the Company or the
Guarantor, as applicable, will be obligated to pay additional cash interest to
each Holder of Transfer Restricted Securities, during the period of one or more
such Registration Defaults, in an amount equal to 0.25% per annum of the
principal amount of Transfer Restricted Securities held by such Holder during
the first 90 day period following such registration default, increasing by an
additional 0.25% per annum during each subsequent 90 day period up to a maximum
of 0.50% per annum, until (i) the applicable Registration Statement is filed,
(ii) the Exchange Offer Registration Statement or the Shelf Registration
Statement, as the case may be, is declared effective, (iii) the

<PAGE>
                                                                               8

Registered Exchange Offer is consummated, or (iv) the Shelf Registration
Statement again becomes effective, as the case may be. Following the cure of all
Registration Defaults, the accrual of additional interest will cease. The
Company shall notify the Trustee immediately upon the happening of each and
every Registration Default. The Company or the Guarantor, as applicable, shall
pay the additional interest due on the Transfer Restricted Securities by
depositing with the Trustee, in trust, for the benefit of the Holders thereof,
on the next interest payment date specified by the Indenture and the Securities,
sums sufficient to pay the additional interest then due. The additional interest
due shall be payable on each interest payment date specified by the Indenture
and the Securities to the record holder entitled to receive the interest payment
to be made on such date. Each obligation to pay additional interest shall be
deemed to accrue from and including the date of the applicable Registration
Default.

         (e) Without limiting the remedies available to the Initial Purchasers
and the Holders, the Company and the Guarantor acknowledge that any failure by
the Company or the Guarantor to comply with their obligations under Section 2(a)
and Section 2(b) hereof may result in material irreparable injury to the Initial
Purchasers or the Holders for which there is no adequate remedy at law, that it
will not be possible to measure damages for such injuries precisely and that, in
the event of any such failure, the Initial Purchasers or any Holder may obtain
such relief as may be required to specifically enforce the Company's and the
Guarantor's obligations under Section 2(a) and Section 2(b) hereof.

         3. Registration Procedures. In connection with their obligations
pursuant to Section 2(a) and Section 2(b) hereof, the Company and the Guarantor
shall as expeditiously as possible:

         (a) prepare and file with the SEC a Registration Statement on the
appropriate form under the Securities Act, which form (x) shall be selected by

Holders thereof and (z) shall comply as to form in all material respects with

to cause such Registration Statement to become effective and remain effective
for the applicable period in accordance with Section 2 hereof;

         (b) prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such

preliminary Prospectus, and any amendment or supplement thereto, as such person
shall reasonably request, in order to facilitate the sale or other disposition
of the Transfer Restricted Securities thereunder; and the Company and the
Guarantor consent to the use of such Prospectus and any amendment or supplement
thereto in accordance with applicable law by each of the selling Holders of
Transfer Restricted Securities and any such Underwriters in connection with the
offering and sale of the Transfer Restricted Securities covered by and in the
manner described in such Prospectus or any amendment or supplement thereto in
accordance with applicable law;

         (d) use their reasonable best efforts to register or qualify, to the
extent required, the Transfer Restricted Securities under all applicable state
securities or blue sky laws of such United States jurisdictions as any Holder of
Transfer Restricted Securities covered by a Registration Statement shall
reasonably request in writing by the time the applicable Registration Statement
is declared effective by the SEC; cooperate with the Holders in connection with
any filings required to be made with the National Association of Securities
Dealers, Inc.; and do any and all other acts and things that may be reasonably
necessary or advisable to enable each Holder to complete the disposition in each
such jurisdiction of the Transfer Restricted Securities owned by such Holder;
provided that neither the Company nor the Guarantor shall be required to (i)
qualify as a foreign corporation or other entity or as a dealer in securities in
any such jurisdiction where it would not otherwise be required to so qualify,
(ii) file any general consent to service of process in any such jurisdiction or
(iii) subject itself to taxation in any such jurisdiction if it is not so
subject;

         (e) in the case of a Shelf Registration, notify each Holder of Transfer
Restricted Securities, counsel for such Holders and counsel for the Initial
Purchasers promptly and, if requested by any such Holder or counsel, confirm
such advice in writing (i) when a Registration Statement has become effective
and when any post-effective amendment thereto has been filed and becomes
effective, (ii) of any request by the SEC or any state securities authority for
amendments and supplements to a Registration Statement and Prospectus or for
additional information after the Registration Statement has become effective,
(iii) of the issuance by the SEC or any state securities authority of any stop
order suspending the effectiveness of a Registration Statement or the initiation
of any proceedings for that purpose, (iv) if, between the effective date of a
Registration Statement and the closing of any sale of Transfer Restricted
Securities covered thereby, the representations and warranties of the Company or
the Guarantor contained in any underwriting agreement, securities sales
agreement or other similar agreement, if any, relating to an offering of such
Transfer Restricted Securities cease to be true and correct in all material
respects or if the Company or the Guarantor receives any notification with
respect to the suspension of the qualification of the Transfer Restricted
Securities for sale in any jurisdiction or the initiation of any proceeding for
such purpose, (v) of the happening of any event during the period a Shelf
Registration Statement is effective that makes any statement made in such
Registration Statement or the related Prospectus untrue in any material respect
or that requires the making of any changes in such Registration Statement or
Prospectus in order to make the statements therein not misleading and (vi) of
any determination by the Company or the Guarantor that a post-effective
amendment to a Registration Statement would be appropriate;

<PAGE>
                                                                              10

reasonably request at least one Business Day prior to the closing of any sale of
Transfer Restricted Securities;

         (i) in the case of a Shelf Registration, upon the occurrence of any
event contemplated by Section 3(e)(v) hereof, use their reasonable best efforts
to prepare and file with the SEC a supplement or post-effective amendment to a
Registration Statement or the related Prospectus or any document incorporated
therein by reference or file any other required document so that, as thereafter
delivered to purchasers of the Transfer Restricted Securities, such Prospectus
will not contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; and the Company and
the Guarantor shall notify the Holders of Transfer Restricted Securities to
suspend use of the Prospectus as promptly as practicable after the occurrence of
such an event, and such Holders hereby agree to suspend use of the Prospectus
until the Company and the Guarantor have amended or supplemented the Prospectus
to correct such misstatement or omission;

         (j) a reasonable time prior to the filing of any Registration
Statement, any Prospectus, any amendment to a Registration Statement or
amendment or supplement to a Prospectus or of any document that is to be
incorporated by reference into a Registration Statement or a Prospectus after
initial filing of a Registration Statement, provide copies of such document to
the Initial Purchasers and their counsel (and, in the case of a Shelf
Registration Statement, to the Holders of Transfer Restricted Securities and
their counsel) and make such of the representatives of the Company and the
Guarantor as shall be reasonably requested by the Initial Purchasers or their
counsel (and, in the case of a Shelf Registration Statement, the Holders of
Transfer Restricted Securities or their counsel) available for discussion of
such document; and the Company and the Guarantor shall not, at any time after
initial filing of a Registration Statement, file any Prospectus, any amendment
of or supplement to a Registration Statement or a Prospectus, or any document
that is to be incorporated by reference into a Registration Statement or a
Prospectus, of which the Initial Purchasers and their counsel (and, in the case
of a Shelf

                                                                              11

Registration Statement, the Holders of Transfer Restricted Securities and their
counsel) shall not have previously been advised and furnished a copy or to which
the Initial Purchasers or their counsel (and, in the case of a Shelf
Registration Statement, the Holders or their counsel) shall reasonably object;

         (k) obtain a CUSIP number for all Exchange Securities or Transfer
Restricted Securities, as the case may be, not later than the effective date of
a Registration Statement;

         (l) to the extent required, cause the Indenture to be qualified under
the Trust Indenture Act in connection with the registration of the Exchange
Securities or Transfer Restricted Securities, as the case may be; cooperate with
the Trustee and the Holders to effect such changes to the Indenture as may be
required for the Indenture to be so qualified in accordance with the terms of
the Trust Indenture Act; and execute, and use their reasonable best efforts to
cause the Trustee to execute, all documents as may be required to effect such
changes and all other forms and documents required to be filed with the SEC to
enable the Indenture to be so qualified in a timely manner;

         (m) in the case of a Shelf Registration, make available for inspection
by a representative of the Holders of the Transfer Restricted Securities (an
"Inspector"), any Underwriter participating in any disposition pursuant to such
Shelf Registration Statement, and attorneys and accountants designated by the
Holders, at reasonable times and in a reasonable manner, all pertinent financial
and other records, documents and properties of the Company and the Guarantor,
and cause the respective officers, directors and employees of the Company and
the Guarantor to supply all information reasonably requested by any such
Inspector, Underwriter, attorney or accountant in connection with a Shelf
Registration Statement, in each case, as shall be reasonably necessary to enable
such persons to conduct a reasonable investigation within the meaning of Section
11 of the Securities Act; provided that if any such information is identified by
the Company or the Guarantor as being confidential or proprietary, each Person
receiving such information shall take such actions as are reasonably necessary
(including execution of a confidentiality agreement reasonably satisfactory to
the Company and the Guarantor) to protect the confidentiality of such
information to the extent such action is otherwise not inconsistent with, an
impairment of or in derogation of the rights and interests of any Inspector,
Holder or Underwriter;

         (n) if reasonably requested by any Holder of Transfer Restricted
Securities covered by a Registration Statement, promptly incorporate in a
Prospectus supplement or post-effective amendment such information with respect
to such Holder as such Holder reasonably requests to be included therein and
make all required filings of such Prospectus supplement or such post-effective
amendment as soon as the Company has received notification of the matters to be
incorporated in such filing; and

         (o) in the case of a Shelf Registration, enter into such customary
agreements and take all such other actions in connection therewith (including
those requested by the Holders of a majority in principal amount of the Transfer
Restricted Securities being sold) in order to expedite or facilitate the
disposition of such Transfer Restricted

<PAGE>
                                                                              12

Securities including, but not limited to, an Underwritten Offering and in such
connection, (i) to the extent possible, make such representations and warranties
to the Holders and any Underwriters of such Transfer Restricted Securities with
respect to the business of the Company and its subsidiaries, the Registration
Statement, Prospectus and documents incorporated by reference or deemed
incorporated by reference, if any, in each case, in form, substance and scope as
are customarily made by issuers to underwriters in underwritten offerings and
confirm the same if and when requested, (ii) obtain opinions of counsel to the
Company and the Guarantor (which counsel and opinions, in form, scope and
substance, shall be reasonably satisfactory to the Holders and such Underwriters
and their respective counsel) addressed to each selling Holder and Underwriter
of Transfer Restricted Securities, covering the matters customarily covered in
opinions requested in underwritten offerings, (iii) obtain "comfort" letters
from the independent certified public accountants of the Company and the
Guarantor (and, if necessary, any other certified public accountant of any
subsidiary of the Company or the Guarantor, or of any business acquired by the
Company or the Guarantor for which financial statements and financial data are
or are required to be included in the Registration Statement) addressed to each
selling Holder and Underwriter of Transfer Restricted Securities, such letters
to be in customary form and covering matters of the type customarily covered in
"comfort" letters in connection with underwritten offerings and (iv) deliver
such documents and certificates as may be reasonably requested by the Holders of
a majority in principal amount of the Transfer Restricted Securities being sold
or the Underwriters, and which are customarily delivered in underwritten
offerings, to evidence the continued validity of the representations and
warranties of the Company and the Guarantor made pursuant to clause (i) above
and to evidence compliance with any customary conditions contained in an
underwriting agreement.

         In the case of a Shelf Registration Statement, the Company may require
each Holder of Transfer Restricted Securities to furnish to the Company such
information regarding such Holder and the proposed disposition by such Holder of
such Transfer Restricted Securities as the Company and the Guarantor may from
time to time reasonably request in writing.

         In the case of a Shelf Registration Statement, each Holder of Transfer
Restricted Securities agrees that, upon receipt of any notice from the Company
and the Guarantor of the happening of any event of the kind described in Section
3(e)(iii) or 3(e)(v) hereof, such Holder will forthwith discontinue disposition
of Transfer Restricted Securities pursuant to a Registration Statement until
such Holder's receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 3(i) hereof and, if so directed by the Company and the
Guarantor, such Holder will deliver to the Company and the Guarantor all copies
in its possession, other than permanent file copies then in such Holder's
possession, of the Prospectus covering such Transfer Restricted Securities that
is current at the time of receipt of such notice.

         If the Company and the Guarantor shall give any such notice to suspend
the disposition of Transfer Restricted Securities pursuant to a Registration
Statement, the Company and the Guarantor shall extend the period during which
the Registration Statement shall be maintained effective pursuant to this
Agreement by the number of

<PAGE>
                                                                              13

days during the period from and including the date of the giving of such notice
to and including the date when the Holders shall have received copies of the
supplemented or amended Prospectus necessary to resume such dispositions. The
Company and the Guarantor may give any such notice only twice during any 365-day
period and any such suspensions shall not exceed 30 days for each suspension and
there shall not be more than two suspensions in effect during any 365-day
period.

         The Holders of Transfer Restricted Securities covered by a Shelf
Registration Statement who desire to do so may sell such Transfer Restricted
Securities in an Underwritten Offering. In any such Underwritten Offering, the
investment banker or investment bankers and manager or managers (the
"Underwriters") that will administer the offering will be selected by the
Majority Holders of the Transfer Restricted Securities included in such
offering.

         4. Participation of Broker-Dealers in Exchange Offer. (a) The Staff of
the SEC has taken the position that any broker-dealer that receives Exchange
Securities for its own account in the Exchange Offer in exchange for Securities
that were acquired by such broker-dealer as a result of market-making or other
trading activities (a "Participating Broker-Dealer") may be deemed to be an
"underwriter" within the meaning of the Securities Act and must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such Exchange Securities.

         The Company and the Guarantor understand that it is the Staff's
position that if the Prospectus contained in the Exchange Offer Registration
Statement includes a plan of distribution containing a statement to the above
effect and the means by which Participating Broker-Dealers may resell the
Exchange Securities, without naming the Participating Broker-Dealers or
specifying the amount of Exchange Securities owned by them, such Prospectus may
be delivered by Participating Broker-Dealers to satisfy their prospectus
delivery obligation under the Securities Act in connection with resales of
Exchange Securities for their own accounts, so long as the Prospectus otherwise
meets the requirements of the Securities Act.

<PAGE>
                                                                              14

         (a) In light of the above, and notwithstanding the other provisions of
this Agreement, the Company and the Guarantor agree to use their reasonable best
efforts to keep the Exchange Offer Registration Statement remain effective and
to amend or supplement the Prospectus contained therein, as would otherwise be
contemplated by Section 3(i), for a period of up to 180 days after the last
Exchange Date (as such period may be extended pursuant to the penultimate
paragraph of Section 3 of this Agreement), if requested by the Initial
Purchasers or by one or more Participating Broker-Dealers, in order to expedite
or facilitate the disposition of any Exchange Securities by Participating
Broker-Dealers consistent with the positions of the Staff recited in Section
4(a) above. The Company and the Guarantor further agree that Participating
Broker-Dealers shall be authorized to deliver such Prospectus during such period
in connection with the resales contemplated by this Section 4.

         (b) The Initial Purchasers shall have no liability to the Company, the
Guarantor or any Holder with respect to any request that they may make pursuant
to Section 4(b) above.

         5. Indemnification and Contribution. (a) The Company and the Guarantor,
jointly and severally, agree to indemnify and hold harmless each Initial
Purchaser and each Holder, their respective affiliates, directors and officers
and each Person, if any, who controls any Initial Purchaser or any Holder within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act, from and against any and all losses, claims, damages and liabilities
(including, without limitation, reasonable legal fees and other expenses
incurred in connection with any suit, action or proceeding or any claim
asserted, as such fees and expenses are incurred), joint or several, that arise
out of, or are based upon, any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement or any Prospectus or any
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, except
insofar as such losses, claims, damages or liabilities arise out of, or are
based upon, any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with any information furnished
to the Company in writing through the Representatives or any selling Holder
expressly for use therein. In connection with any Underwritten Offering
permitted by Section 3, the Company and the Guarantor, jointly and severally,
will also indemnify the Underwriters, if any, selling brokers, dealers and
similar securities industry professionals participating in the distribution,
their respective affiliates and each Person who controls such Persons (within
the meaning of the Securities Act and the Exchange Act) to the same extent as
provided above with respect to the indemnification of the Holders, if requested
in connection with any Registration Statement.

         (b) Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Guarantor, the Initial Purchasers and the other
selling Holders, their respective affiliates, the directors of the Company and
the Guarantor, each officer of the Company and the Guarantor who signed the
Registration Statement and each Person, if any, who controls the Company, the
Guarantor, any Initial Purchaser and any other selling Holder within the meaning
of Section 15 of the Securities Act or

<PAGE>
                                                                              15

Section 20 of the Exchange Act to the same extent as the indemnity set forth in
paragraph (a) above, but only with respect to any losses, claims, damages or
liabilities that arise out of, or are based upon, any untrue statement or
omission or alleged untrue statement or omission made in reliance upon and in
conformity with any information furnished to the Company in writing by such
Holder expressly for use in any Registration Statement and any Prospectus.

         (c) If any suit, action, proceeding (including any governmental or
regulatory investigation), claim or demand shall be brought or asserted against
any Person in respect of which indemnification may be sought pursuant to either
paragraph (a) or (b) above, such Person (the "Indemnified Person") shall
promptly notify the Person against whom such indemnification may be sought (the
"Indemnifying Person") in writing; provided that the failure to notify the
Indemnifying Person shall not relieve it from any liability that it may have
under this Section 5 except to the extent that it has been materially prejudiced
(through the forfeiture of substantive rights or defenses) by such failure; and
provided, further, that the failure to notify the Indemnifying Person shall not
relieve it from any liability that it may have to an Indemnified Person
otherwise than under this Section 5. If any such proceeding shall be brought or
asserted against an Indemnified Person and it shall have notified the
Indemnifying Person thereof, the Indemnifying Person shall retain counsel
reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others entitled to indemnification pursuant to this Section 5
that the Indemnifying Person may designate in such proceeding and shall pay the
fees and expenses of such counsel related to such proceeding, as incurred. In
any such proceeding, any Indemnified Person shall have the right to retain its
own counsel, but the fees and expenses of such counsel shall be at the expense
of such Indemnified Person unless (i) the Indemnifying Person and the
Indemnified Person shall have mutually agreed to the contrary; (ii) the
Indemnifying Person has failed within a reasonable time to retain counsel
reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person
shall have reasonably concluded that there may be legal defenses available to it
that are different from or in addition to those available to the Indemnifying
Person; or (iv) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It is
understood and agreed that the Indemnifying Person shall not, in connection with
any proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred. Any such separate firm (x) for any Initial
Purchaser, its affiliates, directors and officers and any control Persons of
such Initial Purchaser shall be designated in writing by the Representatives,
(y) for any Holder, its affiliates, directors and officers and any control
Persons of such Holder shall be designated in writing by the Majority Holders
and (z) in all other cases shall be designated in writing by the Company. The
Indemnifying Person shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the Indemnifying Person agrees to
indemnify each Indemnified Person from and against any loss or liability by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an Indemnified Person

<PAGE>
                                                                              16

shall have requested that an Indemnifying Person reimburse the Indemnified
Person for fees and expenses of counsel as contemplated by this paragraph, the
Indemnifying Person shall be liable for any settlement of any proceeding
effected without its written consent if (i) such settlement is entered into more
than 30 days after receipt by the Indemnifying Person of such request and (ii)
the Indemnifying Person shall not have reimbursed the Indemnified Person in
accordance with such request prior to the date of such settlement. No
Indemnifying Person shall, without the written consent of the Indemnified
Person, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a party and
indemnification could have been sought hereunder by such Indemnified Person,
unless such settlement (A) includes an unconditional release of such Indemnified
Person, in form and substance reasonably satisfactory to such Indemnified
Person, from all liability on claims that are the subject matter of such
proceeding and (B) does not include any statement as to or any admission of
fault, culpability or a failure to act by or on behalf of any Indemnified
Person.

         (d) If the indemnification provided for in paragraphs (a) and (b) above
is unavailable to an Indemnified Person or insufficient in respect of any
losses, claims, damages or liabilities referred to therein, then each
Indemnifying Person under such paragraph, in lieu of indemnifying such
Indemnified Person thereunder, shall contribute to the amount paid or payable by
such Indemnified Person as a result of such losses, claims, damages or
liabilities (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Guarantor from the offering of the
Securities and the Exchange Securities, on the one hand, and by the Holders from
receiving Securities or Exchange Securities registered under the Securities Act,
on the other hand, or (ii) if the allocation provided by clause (i) is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) but also the relative fault
of the Company and the Guarantor on the one hand and the Holders on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative fault of the Company and the Guarantor on the one
hand and the Holders on the other shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company and the Guarantor or by the Holders and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

         (e) The Company, the Guarantor and the Holders agree that it would not
be just and equitable if contribution pursuant to this Section 5 were determined
by pro rata allocation (even if the Holders were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above. The amount paid or
payable by an Indemnified Person as a result of the losses, claims, damages and
liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses incurred
by such Indemnified Person in connection with any such action or claim.
Notwithstanding the provisions of this Section 5, in no event shall a Holder be
required to contribute any amount in excess of the amount by which the total
price at which the Securities or Exchange Securities sold by such Holder exceeds
the

<PAGE>
                                                                              17

amount of any damages that such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No Person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any Person who was not guilty of such fraudulent misrepresentation.

         (f) The remedies provided for in this Section 5 are not exclusive and
shall not limit any rights or remedies that may otherwise be available to any
Indemnified Person at law or in equity.

         (g) The indemnity and contribution provisions contained in this Section
5 shall remain operative and in full force and effect regardless of (i) any
termination of this Agreement, (ii) any investigation made by or on behalf of
the Initial Purchasers or any Holder, their respective affiliates or any Person
controlling any Initial Purchaser or any Holder, or by or on behalf of the
Company or the Guarantor, their respective affiliates or the officers or
directors of or any Person controlling the Company or the Guarantor, (iii)
acceptance of any of the Exchange Securities and (iv) any sale of Transfer
Restricted Securities pursuant to a Shelf Registration Statement.

         6. General.

         (a) No Inconsistent Agreements. The Company and the Guarantor
represent, warrant and agree that (i) the rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of any other outstanding securities issued or
guaranteed by the Company or the Guarantor under any other agreement and (ii)
neither the Company nor the Guarantor has entered into, or on or after the date
of this Agreement will enter into, any agreement that is inconsistent with the
rights granted to the Holders of Transfer Restricted Securities in this
Agreement or otherwise conflicts with the provisions hereof.

         (b) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
given unless the Company and the Guarantor have obtained the written consent of
Holders of at least a majority in aggregate principal amount of the outstanding
Transfer Restricted Securities affected by such amendment, modification,
supplement, waiver or consent; provided that no amendment, modification,
supplement, waiver or consent to any departure from the provisions of Section 5
hereof shall be effective as against any Holder of Transfer Restricted
Securities unless consented to in writing by such Holder. Any amendments,
modifications, supplements, waivers or consents pursuant to this Section 6(b)
shall be by a writing executed by each of the parties hereto.

         (c) Notices. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telecopier, or any courier guaranteeing overnight delivery (i)
if to a Holder, at the most current address given by such Holder to the Company
by means of a notice given in accordance with the provisions of this Section
6(c), which address initially is, with

<PAGE>
                                                                              18

respect to the Initial Purchasers, the address set forth in the Purchase
Agreement; (ii) if to the Company and the Guarantor, initially at the Company's
address set forth in the Purchase Agreement and thereafter at such other
address, notice of which is given in accordance with the provisions of this
Section 6(c); and (iii) to such other persons at their respective addresses as
provided in the Purchase Agreement and thereafter at such other address, notice
of which is given in accordance with the provisions of this Section 6(c). All
such notices and communications shall be deemed to have been duly given: at the
time delivered by hand, if personally delivered; five Business Days after being
deposited in the mail, postage prepaid, if mailed; when receipt is acknowledged,
if telecopied; and on the next Business Day if timely delivered to an air
courier guaranteeing overnight delivery. Copies of all such notices, demands or
other communications shall be concurrently delivered by the Person giving the
same to the Trustee, at the address specified in the Indenture.

         (d) Successors and Assigns. This Agreement shall inure to the benefit
of and be binding upon the successors, assigns and transferees of each of the
parties, including, without limitation and without the need for an express
assignment, subsequent Holders; provided that nothing herein shall be deemed to
permit any assignment, transfer or other disposition of Transfer Restricted
Securities in violation of the terms of the Purchase Agreement or the Indenture.
If any transferee of any Holder shall acquire Transfer Restricted Securities in
any manner, whether by operation of law or otherwise, such Transfer Restricted
Securities shall be held subject to all the terms of this Agreement, and by
taking and holding such Transfer Restricted Securities such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof. The Initial Purchasers (in their capacity as
Initial Purchasers) shall have no liability or obligation to the Company or the
Guarantor with respect to any failure by a Holder to comply with, or any breach
by any Holder of, any of the obligations of such Holder under this Agreement.

         (e) Purchases and Sales of Securities. The Company and the Guarantor
shall not, and shall use their reasonable best efforts to cause their affiliates
(as defined in Rule 405 under the Securities Act) not to, purchase and then
resell or otherwise transfer any Transfer Restricted Securities.

         (f) Third Party Beneficiaries. Each Holder shall be a third party
beneficiary to the agreements made hereunder between the Company and the
Guarantor, on the one hand, and the Initial Purchasers, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
other Holders hereunder.

         (g) Counterparts. This Agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

<PAGE>
                                                                              19

         (h) Headings. The headings in this Agreement are for convenience of
reference only, are not a part of this Agreement and shall not limit or
otherwise affect the meaning hereof.

         (i) Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

         (j) Miscellaneous. This Agreement contains the entire agreement between
the parties relating to the subject matter hereof and supersedes all oral
statements and prior writings with respect thereto. If any term, provision,
covenant or restriction contained in this Agreement is held by a court of
competent jurisdiction to be invalid, void or unenforceable or against public
policy, the remainder of the terms, provisions, covenants and restrictions
contained herein shall remain in full force and effect and shall in no way be
affected, impaired or invalidated. The Company, the Guarantor and the Initial
Purchasers shall endeavor in good faith negotiations to replace the invalid,
void or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the invalid, void or unenforceable
provisions.

         and the Intermediate Parent has a Bond Rating in effect, in which case,

         the nearest 1/16 of 1% or, if there is no nearest 1/16 of 1%, rounded

         Prime Rate in effect on such day and (b) the Effective Federal Funds

         of such change in the Prime Rate or the Effective Federal Funds Rate,
         respectively.

                  SECTION 1.3. Accounting Terms. All accounting terms not
specifically defined herein shall be construed in accordance with GAAP either
(a) consistent with those principles applied in the preparation of the financial
statements referred to in Section 4.1(e) or (b) not so materially inconsistent
with such principles that a covenant contained in Section 5.1 or 5.2 would be
calculated or construed in a materially different manner or with materially
different results than if such covenant were calculated or construed in
accordance with clause (a) of this Section 1.3. "Include", "includes" and
"including" shall be deemed to be followed by "without limitation" whether or
not they are in fact followed by such words or words of like import. References

modified or supplemented from time to time in accordance with the terms hereof
and thereof.

                  SECTION 1.4. References. The words "hereof", "herein" and
"hereunder" and words of similar import when used in this Agreement shall refer

                                   ARTICLE II

                        AMOUNTS AND TERMS OF THE ADVANCES

                  SECTION 2.1. The Revolving Credit Advances. Each Lender
severally agrees, on the terms and conditions hereinafter set forth, to make
revolving credit advances ("Revolving Credit Advances") to the Borrowers or any
one or more of them from time to time on any Business Day during the period from
the date hereof to and including the Termination Date in an aggregate amount not
to result in such Lender's Revolving Credit Exposure exceeding such Lender's
Commitment; provided that the aggregate principal amount of the Lenders'
Revolving Credit Exposures (other than Revolving Credit Exposures of Objecting
Lenders) outstanding shall not at any time exceed the aggregate amount of the
Commitments. Each Borrowing shall be in an aggregate amount of $5,000,000 in the
case of a Borrowing comprised of Base Rate Advances and $20,000,000 in the case
of a Borrowing comprised of Eurodollar Rate Advances, or, in each case, an
integral multiple of $1,000,000 in excess thereof (or, in the case of a
Borrowing of Base Rate Advances, the aggregate unused Commitments, if less, or
an aggregate amount that is required to finance the reimbursement of an LC
Disbursement as contemplated by Section 2.24) and shall consist of Revolving
Credit Advances of the same Type made on the same day by the Lenders ratably
according to their respective Commitments. Within the limits of each Lender's

                                       15
<PAGE>

Commitment, any Borrower may make more than one Borrowing on any Business Day
and may borrow, repay pursuant to Section 2.10 or prepay pursuant to Section
2.15, and reborrow under this Section 2.1.

                  SECTION 2.2. Making the Revolving Credit Advances. (a) Each
Borrowing of Revolving Credit Advances shall be made on notice by the Company on
its own behalf or the Company on behalf of another Borrower, to the
Administrative Agent (a "Notice of Borrowing") received by the Administrative
Agent, (i) in the case of a proposed Borrowing comprised of Base Rate Advances,
not later than 10:00 A.M. (New York City time) on the Business Day of such
proposed Borrowing and (ii) in the case of a proposed Borrowing comprised of
Eurodollar Rate Advances, not later than 12:00 noon (New York City time) on the
third Business Day prior to the date of such proposed Borrowing. Each Notice of
Borrowing shall be by telecopy or telephone (and if by telephone, confirmed
promptly by telecopier), in substantially the form of Exhibit B, specifying
therein the requested (A) Borrower, (B) date of such Borrowing, (C) Type of
Revolving Credit Advances comprising such Borrowing, (D) aggregate amount of
such Borrowing, and (E) in the case of a Borrowing comprised of Eurodollar Rate
Advances, the initial Interest Period for each such Advance. Each Lender shall,
before 1:00 P.M. (New York City time) on the date of such Borrowing, make
available to the Administrative Agent at its address at 270 Park Avenue, New
York, New York, 10017, Reference: El Paso Corporation, or at such other address
designated by notice from the Administrative Agent to the Lenders pursuant to
Section 9.2, in same day funds, such Lender's ratable portion of such Borrowing.
Immediately after the Administrative Agent's receipt of such funds and upon
fulfillment of the applicable conditions set forth in Article III, the
Administrative Agent will make such funds available to the applicable Borrower
at JPMorgan Chase Bank, 270 Park Avenue, New York, New York, 10017, Account No.
323291503, Reference: El Paso Corporation, or at such other account of the
applicable Borrower maintained by the Administrative Agent (or any successor
Administrative Agent) designated by the applicable Borrower and agreed to by the
Administrative Agent (or such successor Administrative Agent), in same day
funds.

                  (b) Each Notice of Borrowing shall be irrevocable and binding
on the applicable Borrower. In the case of any Borrowing which the related
Notice of Borrowing specified is to be comprised of Eurodollar Rate Advances, if
such Advances are not made as a result of any failure to fulfill on or before
the date specified for such Borrowing the applicable conditions set forth in
Article III, the applicable Borrower shall indemnify each Lender against any
loss, cost or expense incurred by such Lender as a result of such failure,
including, any loss, cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund the
Advance to be made by such Lender as part of such Borrowing.

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

                  (d) The failure of any Lender to make the Advance to be made
by it as part of any Borrowing shall not relieve any other Lender of its
obligation, if any, hereunder to make its Advance on

                                       16
<PAGE>

the date of such Borrowing, but no Lender shall be responsible for the failure
of any other Lender to make the Advance to be made by such other Lender on the
date of any Borrowing.

                  SECTION 2.3. Evidence of Debt. (a) Each Lender shall
maintain in accordance with its usual practice an account or accounts evidencing
indebtedness of each Borrower to such Lender resulting from each Revolving
Credit Advance of such Lender to such Borrower from time to time, including the
amounts of principal and interest payable and paid to such Lender from time to
time in respect of such Revolving Credit Advance.

                  (b) The Administrative Agent shall maintain the Register
pursuant to Section 9.7(c), and a subaccount therein for each Lender, in which
shall be recorded (i) the amount of each Revolving Credit Advance made
hereunder, the Type thereof and each Interest Period applicable thereto, (ii)
the amount of any principal or interest due and payable or to become due and
payable from each Borrower on account of such Revolving Credit Advance to each
Lender hereunder and (iii) both the amount of any sum received by the
Administrative Agent hereunder from each Borrower and each Lender's share
thereof.

                  (c) The entries made in the Register and the accounts of each
Lender maintained pursuant to Section 2.3(a) shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations of each Borrower therein recorded; provided, however, that the
failure of any Lender or the Administrative Agent to maintain the Register or
any such account, or any error therein, shall not in any manner affect the
obligation of each Borrower to repay (with applicable interest) the Revolving
Credit Advances made to each such Borrower by such Lender in accordance with the
terms of this Agreement.

                  (d) Each Borrower agrees that, upon the request to the
Administrative Agent by any Lender, such Borrower will execute and deliver to
such Lender a promissory note of such Borrower evidencing the Revolving Credit
Advances of such Lender to such Borrower, substantially in the form of Exhibit A
with appropriate insertions as to date and principal amount (a "Note").

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

                  SECTION 2.5. Procedure for CAF Advance Borrowings. (a) A
Borrower, or the Company on behalf of a Borrower, shall request CAF Advances by
delivering a CAF Advance Request to the CAF Advance Agent, not later than 12:00
Noon (New York City time) four Business Days prior to the date of the proposed
Borrowing (in the case of a LIBO Rate CAF Advance Request), and not later than
10:00 A.M. (New York City time) one Business Day prior to the date of the
proposed Borrowing (in the case of a Fixed Rate CAF Advance Request). Each CAF
Advance Request may solicit bids for CAF Advances in an aggregate principal
amount of $10,000,000 or an integral multiple of $1,000,000 in excess thereof
and having not more than five alternative maturity dates. The maturity date for
each CAF

                                       17
<PAGE>

Advance shall be not less than 7 days nor more than 360 days after the date of
the Borrowing therefor (and in any event shall be not later than the Stated
Termination Date); provided that each LIBO Rate CAF Advance shall mature one,
two, three or six months or, if available, nine or twelve months after the date
of the Borrowing therefor. The CAF Advance Agent shall notify each CAF Advance
Lender promptly by telecopy of the contents of each CAF Advance Request received
by the CAF Advance Agent.

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

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

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

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

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

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

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

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

                                       18
<PAGE>

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

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

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

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

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

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

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

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

                                       19
<PAGE>

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

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

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

                  (i) A CAF Advance Request may request offers for CAF Advances
to be made on not more than one Borrowing Date and to mature on not more than
five CAF Advance Maturity Dates. No CAF Advance Request may be submitted earlier
than five Business Days after submission of any other CAF Advance Request.

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

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

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

                  SECTION 2.7. Evidence of Debt. Each Lender shall maintain in
accordance with its usual practice appropriate records evidencing indebtedness
of each Borrower to such Lender resulting

                                       20
<PAGE>

from each CAF Advance of such Lender to such Borrower from time to time,
including the amounts of principal and interest payable and paid to such Lender
from time to time in respect of such CAF Advance. The Administrative Agent shall
maintain the Register pursuant to Section 9.7(c) and a record therein for each
Lender, in which shall be recorded (i) the amount of each CAF Advance made by
such Lender to each Borrower, the CAF Advance Maturity Date thereof, the
interest rate applicable thereto and each CAF Advance Interest Payment Date
applicable thereto, and (ii) the amount of any sum received by the
Administrative Agent hereunder from a Borrower on account of such CAF Advance.
The entries made in the Register and the records of each Lender maintained
pursuant to this Section 2.7 shall, to the extent permitted by applicable law,
be prima facie evidence of the existence and amounts of the obligations of each
Borrower therein recorded; provided, however, that the failure of any Lender or
the Administrative Agent to maintain the Register or any such record, or any
error therein, shall not in any manner affect the obligation of each Borrower to
repay (with applicable interest) the CAF Advances made by such Lender in
accordance with the terms of this Agreement.

                  SECTION 2.8. Fees. (a) The Company agrees to pay (i) to
the Administrative Agent for the account of each Lender a facility fee for the
period from and including the Facility Fee Commencement Date until the
Commitment of such Lender has been terminated; provided that, if such Lender
continues to have any Revolving Credit Exposure after its Commitment terminates,
then such facility fee shall continue to accrue on the daily amount of such
Lender's Revolving Credit Exposure from and including the date on which its
Commitment terminates to but excluding the date on which such Lender ceases to
have any Revolving Credit Exposure, computed at a variable rate per annum on the
average daily amount of the greater of (x) the Commitment of such Lender and (y)
the outstanding principal amount of such Lender's Revolving Credit Exposure
during the period for which payment is made, which rate will vary according to
the S&P Bond Rating for the Company and the Moody's Bond Rating for the Company
as set forth in the table below in the column entitled "Facility Fee Rate", (ii)
to the Administrative Agent for the account of each Lender a participation fee
with respect to its participations in Letters of Credit, at a variable rate per
annum (which rate will vary according to the S&P Bond Rating for the Company and
the Moody's Bond Rate for the Company as set forth in the table below in the
column entitled "Participation Fee Rate") on the average daily amount of such
Lender's LC Exposure (excluding any portion thereof attributable to unreimbursed
LC Disbursements) for the period from and including the Facility Fee
Commencement Date to but excluding the later of the date on which such Lender's
Commitment terminates and the date on which such Lender ceases to have any LC
Exposure and (iii) to each applicable Issuing Bank a fronting fee, which shall
accrue at the rate of 0.125 % per annum on the average daily amount of the LC
Exposure attributable to Letters of Credit issued by such Issuing Bank
(excluding any portion thereof attributable to unreimbursed LC Disbursements)
for the period from and including the Facility Fee Commencement Date to but
excluding the later of the date of termination of the Commitments and the date
on which there ceases to be any LC Exposure attributable to Letters of Credit
issued by such Issuing Bank, as well as each applicable Issuing Bank's standard
fees with respect to the issuance, amendment, renewal or extension of any Letter
of Credit issued by it or processing of drawings thereunder. The fees referred
to in clauses (i) and (ii) of the preceding sentence shall be based on the
following table:

provided that (i) if the Bond Ratings of the Company do not fall within the same
Level, the rate applicable to such day will be the percentage opposite the Bond
Rating that is at the higher Level (Level I being the highest and Level VI being
the lowest), (ii) in the event a Bond Rating for the Company is not available
from one of the Rating Agencies, the rate shall be based on the Bond Rating of
the other Rating Agency, and (iii) in the event a Bond Rating for the Company is
available from none of the Rating Agencies, the rate will be the percentage
opposite Level VI. Such facility fees, participation fees and fronting fees
shall be payable quarterly in arrears on the last day of each March, June,
September and December and on the Termination Date or such earlier date on which
the Commitments shall terminate as provided herein, and, if the Lender is an
Objecting Lender, on the Commitment Expiration Date applicable to such Lender
and on the Termination Date (or if the Lender is an Objecting Lender, the
Commitment Expiration Date applicable to such Lender) or such earlier date on
which the Advances are repaid in full, commencing on the first of such dates to
occur after the date hereof. Any other fees payable to an Issuing Bank pursuant
to this paragraph shall be payable within 10 days after demand.

                  (b) The Company agrees to pay to J.P. Morgan Securities Inc.
(fka Chase Securities Inc.), the Administrative Agent and the CAF Advance Agent
the fees set forth in the letter, dated as of July 5, 2000 from Chase Securities
Inc. and The Chase Manhattan Bank (now known as JPMorgan) to the Company.

                  SECTION 2.9. Reduction of the Commitments. The Company shall
have the right, upon at least three Business Days' notice to the Administrative
Agent, to terminate in whole or reduce ratably in part the unused portions of
the respective Commitments of the Lenders, provided that each partial reduction
shall be in the aggregate amount of $10,000,000 or any whole multiple of
$1,000,000 in excess thereof.

                  SECTION 2.10. Repayment of Advances. The Borrowers shall repay
to each Lender on the Termination Date the aggregate principal amount of the
Advances then owing to such Lender; provided that the Revolving Credit Advances
made by Objecting Lenders shall be repaid as provided in Section 2.23.

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

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

                           (ii) Eurodollar Rate Advances. During such periods as
         such Advance is a Eurodollar Rate Advance, at a rate per annum equal at
         all times during each Interest Period for such Advance to the sum of
         the Eurodollar Rate for such Interest Period plus the Applicable
         Eurodollar Rate Margin for such Borrower in effect from time to time,
         payable on the last day of

                                       22
<PAGE>

         each such Interest Period and, if any such Interest Period has a
         duration of more than three months, on each day which occurs during
         such Interest Period every three months from the first day of such
         Interest Period, and on the date such Advance shall be Converted or due
         (whether at stated maturity, by acceleration or otherwise).

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

                  SECTION 2.12. Additional Interest on Eurodollar Rate Advances.
If any Lender shall determine in good faith that reserves under regulations of
the Board of Governors of the Federal Reserve System are required to be
maintained by it in respect of, or a portion of its costs of maintaining
reserves under such regulations is properly attributable to, one or more of its
Eurodollar Rate Advances, the applicable Borrower shall pay to such Lender
additional interest on the unpaid principal amount of each such Eurodollar Rate
Advance to it (other than any such additional interest accruing to a particular
Lender in respect of periods prior to the 30th day preceding the date notice of
such interest is given by such Lender as provided in this Section 2.12), payable
on the same day or days on which interest is payable on such Advance, at an
interest rate per annum equal at all times during each Interest Period for such
Advance to the excess of (i) the rate obtained by dividing the Eurodollar Rate
for such Interest Period by a percentage equal to 100% minus the Eurodollar
Reserve Percentage, if any, for such Lender for such Interest Period over (ii)
the Eurodollar Rate for such Interest Period. The amount of such additional
interest (if any) shall be determined by each Lender, and such Lender shall
furnish written notice of the amount of such additional interest to the Company
and the Administrative Agent, which notice shall be conclusive and binding for
all purposes, absent manifest error.

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

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

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

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

                                       23
<PAGE>

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

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

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

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

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

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

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

                  (g) If any Reference Lender shall for any reason no longer
have a Commitment or any Revolving Credit Advances, such Reference Lender shall
thereupon cease to be a Reference Lender, and if, as a result, there shall only
be one Reference Lender remaining, the Administrative Agent (after consultation
with the Company and the Lenders) shall, by notice to the Company and the
Lenders, designate another Lender as a Reference Lender so that there shall at
all times be at least two Reference Lenders.

                  SECTION 2.14. Voluntary Conversion of Advances. Any Borrower
may on any Business Day, upon notice given to the Administrative Agent, not
later than 10:00 A.M. (New York City time) on the Business Day of the proposed
Conversion of Eurodollar Rate Advances to Base Rate Advances and not later than
12:00 noon (New York City time) on the third Business Day prior to the date of
the proposed Conversion in the case of a Conversion of Base Rate Advances to
Eurodollar Rate

                                       24
<PAGE>

Advances, and subject to the provisions of Sections 2.13, 2.16 and 2.18, Convert
all Advances of one Type comprising the same Borrowing into Advances of another
Type; provided, however, that any Conversion of any Eurodollar Rate Advances
into Base Rate Advances made on any day other than the last day of an Interest
Period for such Eurodollar Rate Advances shall be subject to the provisions of
Section 9.4(b); and provided, further, that no Revolving Credit Advance may be
converted into a Eurodollar Rate Advance after the date that is one month prior
to (a) in the case of a Revolving Credit Advance made by an Objecting Lender,
such Objecting Lender's Commitment Expiration Date, and (b) in the case of all
Revolving Credit Advances, the Termination Date and provided, still further,
that no Revolving Credit Advance may be converted into a Eurodollar Rate Advance
if an Event of Default has occurred and is continuing. Each such notice of a
Conversion shall, within the restrictions specified above, specify (a) the date
of such Conversion, (b) the Advances to be Converted, and (c) if such Conversion
is into Eurodollar Rate Advances, the duration of the Interest Period for each
such Advance.

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

                  (b) Mandatory Prepayments. If, at any time and from time to
time, the aggregate principal amount of Advances (other than Advances of
Objecting Lenders) then outstanding exceeds the Commitments of all the Lenders
after giving effect to any reduction of the Commitments pursuant to Section 2.9,
the Borrowers shall immediately prepay the Revolving Credit Advances of Lenders
(other than Objecting Lenders) (to the extent there are such outstanding
Revolving Credit Advances) by an amount equal to such excess.

                  SECTION 2.16. Increased Costs. (a) If, due to either (i)
the introduction after the date of this Agreement of or any change after the
date of this Agreement (including any change by way of imposition or increase of
reserve requirements or assessments other than those referred to in the
definition of "Eurodollar Reserve Percentage" contained in Section 1.1) in or in
the interpretation of any law or regulation or (ii) the compliance with any
guideline or request issued or made after the date of this Agreement from or by
any central bank or other governmental authority (whether or not having the
force of law), in each case above other than those referred to in Section 2.17,
there shall be any increase in the cost to any Lender of agreeing to make, fund
or maintain, or of making, funding or maintaining, Eurodollar Rate Advances
funded in the interbank Eurodollar market or of maintaining its LC Exposure, or
to any Issuing Bank of agreeing to issue or maintain Letters of Credit
hereunder, then the Borrowers shall from time to time, upon demand by such
Lender or Issuing Bank, as applicable (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender or Issuing Bank, as applicable, additional amounts sufficient to
reimburse such Lender or Issuing Bank, as applicable, for all such increased
costs (except those costs incurred more than 60 days prior to the date of such
demand; for the purposes hereof any cost or expense allocable to a period prior
to the publication or

                                       25
<PAGE>

effective date of such an introduction, change, guideline or request shall be
deemed to be incurred on the later of such publication or effective date). Each
Lender or Issuing Bank, as applicable, agrees to use its best efforts promptly
to notify the Company of any event referred to in clause (i) or (ii) above,
provided that the failure to give such notice shall not affect the rights of any
Lender or Issuing Bank, as applicable, under this Section 2.16(a) (except as
otherwise expressly provided above in this Section 2.16(a)). A certificate as to
the amount of such increased cost, submitted to the Company and the
Administrative Agent by such Lender or Issuing Bank, as applicable, shall be
conclusive and binding for all purposes, absent manifest error. After one or
more Lenders have notified the Company of any increased costs pursuant to this
Section 2.16, the Company may specify by notice to the Administrative Agent and
the affected Lenders that, after the date of such notice whenever the election
of Eurodollar Rate Advances by the applicable Borrower for an Interest Period or
portion thereof would give rise to such increased costs, such election shall not
apply to the Revolving Credit Advances of such Lenders during such Interest
Period or portion thereof, and, in lieu thereof, such Revolving Credit Advances
shall during such Interest Period or portion thereof be Base Rate Advances. Each
Lender and Issuing Bank agrees to use its best efforts (including a reasonable
effort to change its lending office or the office from which the Issuing Bank
issues or maintains Letters of Credit hereunder, as applicable, or to transfer
its affected Advances or Letters of Credit to an affiliate of such Lender or
Issuing Bank, as applicable ) to avoid, or minimize the amount of, any demand
for payment from the Borrowers under this Section 2.16.

                  (b) In the event that any Lender shall change its lending
office, or any Issuing Bank shall change the office from which it issues or
maintains Letters of Credit hereunder, and such change results (at the time of
such change) in increased costs to such Lender or Issuing Bank, as applicable,
the Borrowers shall not be liable to such Lender or Issuing Bank, as applicable,
for such increased costs incurred by such Lender or Issuing Bank, as applicable,
to the extent, but only to the extent, that such increased costs shall exceed
the increased costs which such Lender or Issuing Bank, as applicable, would have
incurred if the lending office of such Lender, or the office from which such
Issuing Bank issues or maintains Letters of Credit hereunder, as applicable, had
not been so changed, but, subject to subsection (a) above and to Section 2.18,
nothing herein shall require any Lender or Issuing Bank, as applicable, to
change its lending office, or the office from which such Issuing Bank issues or
maintains Letters of Credit hereunder, as applicable, for any reason.

                  SECTION 2.17. Increased Capital. If either (a) the
introduction of or any change in or in the interpretation of any law or
regulation or (b) compliance by any Lender or Issuing Bank, as applicable, with
any guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by such Lender or Issuing Bank, as
applicable, or any corporation controlling such Lender or Issuing Bank, as
applicable, and such Lender or Issuing Bank, as applicable, determines that the
amount of such capital is increased by or based upon the existence of such
Lender's commitment to lend hereunder or such Issuing Bank's commitment to issue
Letters of Credit hereunder, as applicable, and other commitments of such type,
then, within ten days after demand, and delivery to the Company of the
certificate referred to in the last sentence of this Section 2.17 by such Lender
or Issuing Bank, as applicable (with a copy of such demand to the Administrative
Agent), the applicable Borrowers shall pay to the Administrative Agent for the
account of such Lender or Issuing Bank, as applicable, from time to time as
specified by such Lender or Issuing Bank, as applicable, additional amounts
sufficient to compensate such Lender or Issuing Bank, as applicable, or such
corporation in the light of such circumstances, to the extent that such Lender
or Issuing Bank, as applicable, reasonably determines such increase in capital
to be allocable to the existence of such Lender's commitment to lend hereunder
or such Issuing Bank's commitment to issue Letters of Credit hereunder, as
applicable (except any such increase in capital incurred more than, or
compensation attributable to the period before, 90 days prior to the date of
such demand; for the purposes hereof any increase in capital allocable to, or
compensation attributable to, a period prior to the publication or effective
date of such an introduction, change, guideline or request

                                       26
<PAGE>

shall be deemed to be incurred on the later of such publication or effective
date). Each Lender and Issuing Bank agrees to use its best efforts promptly to
notify the Company of any event referred to in clause (a) or (b) above, provided
that the failure to give such notice shall not affect the rights of any Lender
or Issuing Bank under this Section 2.17 (except as otherwise expressly provided
above in this Section 2.17). A certificate in reasonable detail as to the basis
for, and the amount of, such compensation submitted to the Company by such
Lender or Issuing Bank, as applicable, shall, in the absence of manifest error,
be conclusive and binding for all purposes.

                  SECTION 2.18. Illegality. Notwithstanding any other provision
of this Agreement, if the introduction of or any change in or in the
interpretation of any law or regulation shall make it unlawful, or any central
bank or other governmental authority shall assert that it is unlawful, for any
Lender or its lending office to perform its obligations hereunder to make
Eurodollar Rate Advances or to continue to fund or maintain such Advances
hereunder, such Lender may, by notice to the Company and the Administrative
Agent, suspend the right of the Borrowers to elect Eurodollar Rate Advances from
such Lender and, if necessary in the reasonable opinion of such Lender to comply
with such law or regulation, Convert all such Eurodollar Rate Advances of such
Lender to Base Rate Advances at the latest time permitted by the applicable law
or regulation, and such suspension and, if applicable, such Conversion shall
continue until such Lender notifies the Company and the Administrative Agent
that the circumstances making it unlawful for such Lender to perform such
obligations no longer exist (which such Lender shall promptly do when such
circumstances no longer exist). So long as the obligation of any Lender to make
Eurodollar Rate Advances has been suspended under this Section 2.18, all Notices
of Borrowing specifying Advances of such Type shall be deemed, as to such
Lender, to be requests for Base Rate Advances. Each Lender agrees to use its
best efforts (including a reasonable effort to change its lending office or to
transfer its affected Advances to an affiliate) to avoid any such illegality.

                  SECTION 2.19. Pro Rata Treatment, Payments and Computations.
(a) Each Borrowing by any Borrower in respect of Revolving Credit Advances
(subject to the provisions of Section 2.24(e)) shall be made pro rata according
to the respective Commitment Percentages of the Lenders. The Borrowers shall
make each payment hereunder (including under Section 2.6, 2.8, 2.10 or 2.11, and
reimbursement of LC Disbursements) and under the Notes, whether the amount so
paid is owing to any or all of the Lenders or to the Administrative Agent, not
later than 12:00 noon (New York City time) without setoff, counterclaim, or any
other deduction whatsoever, on the day when due in Dollars to the Administrative
Agent at its address at 270 Park Avenue, New York, New York 10017, Reference: El
Paso Corporation, or at such other location designated by notice to the Company
from the Administrative Agent and agreed to by the Company, in same day funds.
The Administrative Agent will promptly thereafter cause to be distributed like
funds relating to the payment of principal or interest or facility fees, or
reimbursements of LC Disbursements, ratably (other than amounts payable pursuant
to Section 2.12, 2.16, 2.17, 2.18 or 2.20) according to the respective amounts
of such principal, interest or facility fees, or reimbursements of LC
Disbursements, then due and owing to the Lenders, and like funds relating to the
payment of any other amount payable to any Lender to such Lender, in each case
to be applied in accordance with the terms of this Agreement. Upon its
acceptance of an Assignment and Acceptance and recording of the information
contained therein in the Register pursuant to Section 9.7(d), from and after the
effective date specified in such Assignment and Acceptance, the Administrative
Agent shall make all payments hereunder and under the Notes in respect of the
interest assigned thereby to the Lender assignee thereunder, and the parties to
such Assignment and Acceptance shall make all appropriate adjustments in such
payments for periods prior to such effective date directly between themselves.

                  (b) All computations of interest based on the Prime Rate and
of fees referred to in clauses (i), (ii) and (iii) of Section 2.8(a) shall be
made by the Administrative Agent on the basis of a year of 365 or 366 days, as
the case may be, and all computations of interest based on the Eurodollar Rate
or the Effective Federal Funds Rate shall be made by the Administrative Agent,
and all computations of

                                       27
<PAGE>

interest pursuant to Section 2.12 shall be made by each Lender with respect to
its own Advances, on the basis of a year of 360 days, in each case for the
actual number of days (including the first day but excluding the last day)
occurring in the period for which such interest or fees are payable. Each
determination by the Administrative Agent (or, in the case of Section 2.12,
2.16, 2.17, 2.18 or 2.20, by each Lender with respect to its own Advances or
each Issuing Bank with respect to its Letters of Credit, as applicable) of an
interest rate or an increased cost or increased capital or of illegality
hereunder shall be conclusive and binding for all purposes if made reasonably
and in good faith.

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

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

                  SECTION 2.20. Taxes. (a) Any and all payments by the
Borrowers hereunder or under the Notes to each Indemnified Party shall be made,
in accordance with Section 2.19, free and clear of and without deduction for any
and all present or future taxes, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto, excluding all taxes,
levies, imposts, deductions, charges or withholdings, and all liabilities with
respect thereto, imposed by the jurisdiction under the laws of which such
Indemnified Party is organized, domiciled, resident or doing business, or any
political subdivision thereof or by any jurisdiction in which such Indemnified
Party holds any interest in connection with this Agreement or any Note
(including in the case of each Lender or Issuing Bank, the jurisdiction of such
Lender's lending office or the office from which such Issuing Bank issues or
maintains its Letters of Credit, as applicable) or any political subdivision
thereof, other than by any jurisdiction with which the Indemnified Party's
connection arises solely from having executed, delivered or performed
obligations or received a payment under, or enforced, this Agreement or any Note
(all such non-excluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as "Taxes"). If any Borrower shall
be required by law to deduct any Taxes from or in respect of any sum payable
hereunder or under any Note to any Indemnified Party, (i) the sum payable shall
be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.20) such Indemnified Party receives an amount equal to the sum it would have
received had no such deductions been made, (ii) such Borrower shall make or
cause to be made such deductions and (iii) such Borrower shall pay or cause to
be paid the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law, provided that the Borrowers shall
not be required to pay any additional amount (and shall be relieved of any
liability with respect thereto) pursuant to this subsection (a) to any
Indemnified Party that either (A) on the date such Lender or Issuing Bank became
an Indemnified Party hereunder, (I) was not entitled to submit a U.S. Internal
Revenue Service form 1001 (relating to such Indemnified Party, and entitling it
to a

                                       28
<PAGE>

complete exemption from United States withholding taxes on all amounts to be
received by such Indemnified Party pursuant to this Agreement) and a U.S.
Internal Revenue Service form 4224 (relating to all amounts to be received by
such Indemnified Party pursuant to this Agreement) and (II) was not a United
States person (as such term is defined in Section 7701(a)(30) of the Internal
Revenue Code) or (B) has failed to submit any form or certificate that it was
required to file or provide pursuant to subsection (d) of this Section 2.20 and
is entitled to file or give, as applicable, under applicable law, provided,
further, that should an Indemnified Party become subject to Taxes because of its
failure to deliver a form required hereunder, the Borrowers shall take such
steps as such Indemnified Party shall reasonably request to assist such
Indemnified Party to recover such Taxes, and provided, further, that each
Indemnified Party, with respect to itself, agrees to indemnify and hold harmless
the Borrowers from any taxes, penalties, interest and other expenses, costs and
losses incurred or payable by the Borrowers as a result of the failure of any of
the Borrowers to comply with its obligations under clause (ii) or (iii) above in
reliance on any form or certificate provided to it by such Indemnified Party
pursuant to this Section 2.20. If any Indemnified Party receives a net credit or
refund in respect of such Taxes or amounts so paid by the Borrowers, it shall
promptly notify the Company of such net credit or refund and shall promptly pay
such net credit or refund to the applicable Borrower, provided that the
applicable Borrower agrees to return such net credit or refund if the
Indemnified Party to which such net credit or refund is applicable is required
to repay it.

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

                  (c) Each Borrower will indemnify each Indemnified Party and
the Administrative Agent for the full amount of Taxes or Other Taxes (including
any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under
this Section 2.20) paid by such Indemnified Party and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto
except as a result of the gross negligence (which shall in any event include the
failure of such Indemnified Party to provide to the Borrowers any form or
certificate that it was required to provide pursuant to subsection (d) below) or
willful misconduct of such Indemnified Party, whether or not such Taxes or Other
Taxes were correctly or legally asserted. This indemnification shall be made
within 30 days from the date such Indemnified Party makes written demand
therefor.

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

                                       29
<PAGE>

official application or interpretation thereof, that it is unable to submit to
the Company any form or certificate that such Indemnified Party is obligated to
submit pursuant to this subsection (d), or that such Indemnified Party is
required to withdraw or cancel any such form or certificate previously
submitted, such Indemnified Party shall promptly notify the Company of such
fact.

                  (e) Any Indemnified Party claiming any additional amounts
payable pursuant to this Section 2.20 shall use its best efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its lending office or the office from which it issues or
maintains its Letters of Credit, as applicable, if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
which may thereafter accrue and would not, in the reasonable judgment of such
Indemnified Party, be otherwise disadvantageous to such Indemnified Party.

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

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

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

                  SECTION 2.22. Use of Proceeds. Proceeds of the Advances and
Letters of Credit may be used for general business purposes of the Borrowers and
their respective Subsidiaries, including for acquisitions and for payment of
commercial paper issued by the Borrowers, and to refinance any Indebtedness of
the Borrowers and their respective Subsidiaries (whether in connection with any
acquisition or otherwise) and to reimburse LC Disbursements.

                  SECTION 2.23. Extension of Stated Termination Date. (a)
Not less than 45 days and not more than 60 days prior to the Stated Termination
Date then in effect, provided that no Event of Default shall have occurred and
be continuing, the Company may request an extension of such Stated Termination
Date by submitting to the Administrative Agent an Extension Request containing
the information in respect of such extension specified in Exhibit M, which the
Administrative Agent shall promptly furnish to each Lender and each Issuing
Bank. Each Lender and each Issuing Bank shall, not less than 30 days and not
more than 60 days prior to the Stated Termination Date then in effect, notify
the

                                       30
<PAGE>

Company and the Administrative Agent of its election to extend or not extend the
Stated Termination Date as requested in such Extension Request. Notwithstanding
any provision of this Agreement to the contrary, any notice by any Lender or
Issuing Bank, as applicable, of its willingness to extend the Stated Termination
Date shall be revocable by such Lender or Issuing Bank, as applicable, in its
sole and absolute discretion at any time prior to the date which is 30 days
prior to the Stated Termination Date then in effect. If the Required Lenders
shall approve in writing the extension of the Stated Termination Date requested
in such Extension Request, the Stated Termination Date shall automatically and
without any further action by any Person be extended for the period specified in
such Extension Request; provided that (i) each extension pursuant to this
Section 2.23 shall be for a maximum of three years, (ii) the Commitment of any
Lender that does not consent in writing, or which revokes, in accordance with
the provisions of this Section 2.23, its consent to such extension not less than
30 days and not more than 60 days prior to the Stated Termination Date then in
effect and has not thereafter reinstated its consent (an "Objecting Lender")
shall, unless earlier terminated in accordance with this Agreement, expire on
the Stated Termination Date in effect on the date of such Extension Request
(such Stated Termination Date, if any, being referred to as the "Commitment
Expiration Date" with respect to such Objecting Lender) and (iii) if an Issuing
Bank shall not have consented to such extension, such Issuing Bank shall be
replaced in accordance with Section 2.24(i). If, not less than 30 days and not
more than 60 days prior to the Stated Termination Date then in effect, the
Required Lenders shall not approve in writing the extension of the Stated
Termination Date requested in an Extension Request, the Stated Termination Date
shall not be extended pursuant to such Extension Request. The Administrative
Agent shall promptly notify (y) the Lenders and each Issuing Bank and the
Company of any extension of the Stated Termination Date pursuant to this Section
2.23 and (z) the Company and the Lenders of any Lender which becomes an
Objecting Lender and of the failure by an Issuing Bank to consent to any
Extension Request.

                  (b) Revolving Credit Advances or participations in LC
Disbursements owing to any Objecting Lender on the Commitment Expiration Date
with respect to such Lender shall be repaid in full on or before such Commitment
Expiration Date.

                  (c) The Borrowers shall have the right, so long as no Event of
Default has occurred and is then continuing, upon giving notice to the
Administrative Agent and the Objecting Lenders in accordance with Section 2.15,
to prepay in full the Revolving Credit Advances and participations in LC
Disbursements of the Objecting Lenders, together with accrued interest thereon,
any amounts payable pursuant to Sections 2.11, 2.12, 2.16, 2.17, 2.18, 2.20 and
9.4(b) and any accrued and unpaid facility fee or other amounts payable to the
Objecting Lenders hereunder and/or, upon giving not less than three Business
Days' notice to the Objecting Lenders and the Administrative Agent, to cancel
the whole or part of the Commitments of the Objecting Lenders.

                  (d) Notwithstanding the foregoing, if any Lender becomes an
Objecting Lender, the Borrower may, at its own expense and in its sole
discretion and prior to the then Stated Termination Date, require such Lender to
transfer or assign, in whole or in part, without recourse (in accordance with
Section 9.7), all or part of its interests, rights and obligations under this
Agreement to an Eligible Assignee (provided that the Borrower, with the full
cooperation of such Lender, can identify an Eligible Assignee that is ready,
willing and able to be an assignee with respect thereto) which shall assume such
assigned obligations (which assignee may be another Lender, if such assignee
Lender accepts such assignment); provided that (A) the assignee or the Borrower,
as the case may be, shall have paid to such Lender in immediately available
funds the principal of and interest accrued to the date of such payment on the
Advances made by it hereunder and all other amounts owed to it hereunder,
including any amounts owing pursuant to Section 9.4(b) and any amounts that
would be owing under said Section if such Advances were prepaid on the date of
such assignment, and (B) such assignment does not conflict with any law, rule or
regulation or order of any governmental authority. Any assignee which becomes a

                                       31
<PAGE>

Lender as a result of such an assignment made pursuant to this paragraph (d)
shall be deemed to have consented to the applicable Extension Request and,
therefore, shall not be an Objecting Lender.

                  SECTION 2.24. Letters of Credit. (a) General. Subject to the
terms and conditions set forth herein, each Borrower may request the issuance of
Letters of Credit for its own account, in a form reasonably acceptable to the
Administrative Agent and the applicable Issuing Bank, at any time and from time
to time on any Business Day during the period from the date hereof to and
including the Termination Date. In the event of any inconsistency between the
terms and conditions of this Agreement and the terms and conditions of any form
of letter of credit application or other agreement submitted by the Borrower to,
or entered into by the Borrower with, the applicable Issuing Bank relating to
any Letter of Credit, the terms and conditions of this Agreement shall control.

                  (b) Notice of Issuance, Amendment, Renewal, Extension; Certain
Conditions. To request the issuance of a Letter of Credit (or the amendment,
renewal or extension of an outstanding Letter of Credit), a Borrower shall hand
deliver or telecopy (or transmit by electronic communication, if arrangements
for doing so have been approved by the applicable Issuing Bank) to the
applicable Issuing Bank and the Administrative Agent (reasonably in advance of
the requested date of issuance, amendment, renewal or extension) a notice
requesting the issuance of a Letter of Credit, or identifying the Letter of
Credit to be amended, renewed or extended, and specifying the date of issuance,
amendment, renewal or extension (which shall be a Business Day), the date on
which such Letter of Credit is to expire (which shall comply with paragraph (c)
of this Section), the amount of such Letter of Credit, the name and address of
the beneficiary thereof and such other information as shall be necessary to
prepare, amend, renew or extend such Letter of Credit. If requested by the
applicable Issuing Bank, the Borrower also shall submit a letter of credit
application on the applicable Issuing Bank's standard form in connection with
any request for a Letter of Credit, with such modifications thereto as agreed
between such Borrower and the applicable Issuing Bank. A Letter of Credit shall
be issued, amended, renewed or extended only if (and upon issuance, amendment,
renewal or extension of each Letter of Credit the Borrower shall be deemed to
represent and warrant that), after giving effect to such issuance, amendment,
renewal or extension (i) the LC Exposure shall not exceed $500,000,000 and (ii)
the sum of the total Revolving Credit Exposures shall not exceed the total
Commitments. Each Issuing Bank will send to the Company and the Administrative
Agent immediately upon issuance of any Letter of Credit, an amendment thereto,
or any renewal or extension thereof, a true and complete copy of such Letter of
Credit, amendment, renewal or extension. Within ten (10) days after the
beginning of each month, the Administrative Agent shall give each Lender written
notice of all Letters of Credit issued, amended, increased or extended during
the preceding month; provided that the failure of the Administrative Agent to so
notify each Lender shall not limit or impair the Obligations of the Borrowers
with respect thereto or the participation of any Lender in such Letter of Credit
as created in clause (d) below.

                  (c) Expiration Date. Each Letter of Credit shall expire at or
prior to the close of business on the earlier of (i) the date one year after the
date of the issuance of such Letter of Credit (or, in the case of any renewal or
extension thereof, one year after such renewal or extension) and (ii) the date
that is five Business Days prior to the Stated Termination Date.

                  (d) Participations. By the issuance of a Letter of Credit (or
an amendment to a Letter of Credit increasing the amount thereof) and without
any further action on the part of the applicable Issuing Bank or the Lenders,
the applicable Issuing Bank hereby grants to each Lender, and each Lender hereby
acquires from the applicable Issuing Bank, a participation in such Letter of
Credit equal to such Lender's Commitment Percentage of the aggregate amount
available to be drawn under such Letter of Credit. In consideration and in
furtherance of the foregoing, each Lender hereby absolutely and unconditionally
agrees to pay to the Administrative Agent, for the account of the applicable
Issuing Bank, such Lender's Commitment Percentage of each LC Disbursement made
by the applicable Issuing Bank and not

                                       32
<PAGE>

reimbursed by the Borrowers on the date due as provided in paragraph (e) of this
Section, or of any reimbursement payment required to be refunded to any Borrower
for any reason. Each Lender acknowledges and agrees that its obligation to
acquire participations pursuant to this paragraph in respect of Letters of
Credit is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including any amendment, renewal or extension of any
Letter of Credit or the occurrence and continuance of a Default or reduction or
termination of the Commitments, and that each such payment shall be made without
any offset, abatement, withholding or reduction whatsoever.

                  (e) Reimbursement. If the applicable Issuing Bank shall make
any LC Disbursement in respect of a Letter of Credit, the Borrower for whose
account such Letter of Credit was issued shall reimburse such LC Disbursement by
paying to the Administrative Agent an amount equal to such LC Disbursement not
later than 12:00 noon, New York City time, on the date that such LC Disbursement
is made, if such Borrower shall have received notice of such LC Disbursement
prior to 10:00 a.m., New York City time, on such date, or, if such notice has
not been received by such Borrower prior to such time on such date, then not
later than 12:00 noon, New York City time, on (i) the Business Day that such
Borrower receives such notice, if such notice is received prior to 10:00 a.m.,
New York City time, on the day of receipt, or (ii) the Business Day immediately
following the day that such Borrower receives such notice, if such notice is not
received prior to such time on the day of receipt; provided that such Borrower
may, subject to the conditions to borrowing set forth herein, request in
accordance with Section 2.2 that such payment be financed with a Base Rate
Advance in an equivalent amount and, to the extent so financed, such Borrower's
obligation to make such payment shall be discharged and replaced by the
resulting Base Rate Advance. If a Borrower fails to make such payment when due,
the Administrative Agent shall notify each Lender of the applicable LC
Disbursement, the payment then due from such Borrower in respect thereof and
such Lender's Commitment Percentage thereof. Promptly following receipt of such
notice, each Lender shall pay to the Administrative Agent its Commitment
Percentage of the payment then due from the applicable Borrower, in the same
manner as provided in Section 2.19 with respect to Advances made by such Lender
(and Section 2.19 shall apply, mutatis mutandis, to the payment obligations of
the Lenders), and the Administrative Agent shall promptly pay to the applicable
Issuing Bank the amounts so received by it from the Lenders. Promptly following
receipt by the Administrative Agent of any payment from the Borrower pursuant to
this paragraph, the Administrative Agent shall distribute such payment to the
applicable Issuing Bank or, to the extent that Lenders have made payments
pursuant to this paragraph to reimburse the applicable Issuing Bank, then to
such Lenders and the applicable Issuing Bank as their interests may appear. Any
payment made by a Lender pursuant to this paragraph to reimburse the applicable
Issuing Bank for any LC Disbursement (other than the funding of Base Rate
Advance as contemplated above) shall not constitute an Advance and shall not
relieve the Borrower of its obligation to reimburse such LC Disbursement.

                  (f) Obligations Absolute. Each Borrower's obligation to
reimburse LC Disbursements as provided in paragraph (e) of this Section shall be
absolute, unconditional and irrevocable, and shall be performed strictly in
accordance with the terms of this Agreement under any and all circumstances
whatsoever and irrespective of (i) any lack of validity or enforceability of any
Letter of Credit or this Agreement, or any term or provision therein, (ii) any
draft or other document presented under a Letter of Credit proving to be forged,
fraudulent or invalid in any respect or any statement therein being untrue or
inaccurate in any respect, (iii) payment by the applicable Issuing Bank under a
Letter of Credit against presentation of a draft or other document that does not
comply with the terms of such Letter of Credit, or (iv) any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that
might, but for the provisions of this Section, constitute a legal or equitable
discharge of, or provide a right of setoff against, a Borrower's obligations
hereunder. Neither the Administrative Agent, the Lenders nor any Issuing Bank,
nor any of their Related Parties, shall have any liability or responsibility by
reason of or in connection with the issuance or transfer of any Letter of Credit
or any payment or failure to make any payment thereunder (irrespective of any of
the circumstances referred to in the preceding sentence),

                                       33
<PAGE>

or any error, omission, interruption, loss or delay in transmission or delivery
of any draft, notice or other communication under or relating to any Letter of
Credit (including any document required to make a drawing thereunder), any error
in interpretation of technical terms or any consequence arising from causes
beyond the control of the applicable Issuing Bank; provided that the foregoing
shall not be construed to excuse the applicable Issuing Bank from liability to a
Borrower to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by the applicable Borrower
to the extent permitted by applicable law) suffered by a Borrower that are
caused by the applicable Issuing Bank's failure to exercise care when
determining whether drafts and other documents presented under a Letter of
Credit issued by it comply with the terms thereof. The parties hereto expressly
agree that, in the absence of gross negligence or willful misconduct on the part
of the applicable Issuing Bank (as finally determined by a court of competent
jurisdiction), the applicable Issuing Bank shall be deemed to have exercised
care in each such determination. In furtherance of the foregoing and without
limiting the generality thereof, the parties agree that, with respect to
documents presented which appear on their face to be in substantial compliance
with the terms of a Letter of Credit, the applicable Issuing Bank may, in its
sole discretion, either accept and make payment upon such documents without
responsibility for further investigation, regardless of any notice or
information to the contrary, or refuse to accept and make payment upon such
documents if such documents are not in strict compliance with the terms of such
Letter of Credit.

                  (g) Disbursement Procedures. The applicable Issuing Bank
shall, promptly following its receipt thereof, examine all documents purporting
to represent a demand for payment under a Letter of Credit issued by it. The
applicable Issuing Bank shall promptly notify the Administrative Agent and the
Borrower for whose account the relevant Letter of Credit was issued by telephone
(confirmed by telecopy) of such demand for payment and whether the applicable
Issuing Bank has made or will make an LC Disbursement thereunder; provided that
any failure to give or delay in giving such notice shall not relieve such
Borrower of its obligation to reimburse the applicable Issuing Bank and the
Lenders with respect to any such LC Disbursement.

                  (h) Interim Interest. If the applicable Issuing Bank shall
make any LC Disbursement, then, unless the Borrower for whose account the
relevant Letter of Credit was issued shall reimburse such LC Disbursement in
full on the date such LC Disbursement is made, the unpaid amount thereof shall
bear interest, for each day from and including the date such LC Disbursement is
made to but excluding the date that such Borrower reimburses such LC
Disbursement, at the rate per annum then applicable to Base Rate Advances;
provided that, if such Borrower fails to reimburse such LC Disbursement when due
pursuant to paragraph (e) of this Section, then Section 2.11(b) shall apply.
Interest accrued pursuant to this paragraph shall be for the account of the
applicable Issuing Bank, except that interest accrued on and after the date of
payment by any Lender pursuant to paragraph (e) of this Section to reimburse the
applicable Issuing Bank shall be for the account of such Lender to the extent of
such payment.

                  (i) Replacement of an Issuing Bank. Any Issuing Bank may be
replaced at any time (i) in the circumstances provided for in Section 2.23 and
Section 2.25 and (ii) otherwise, by written agreement among the Borrower, the
Administrative Agent, the replaced Issuing Bank and any successor Issuing Bank.
The Administrative Agent shall notify the Lenders of any additional Issuing Bank
and of any such replacement of any Issuing Bank. At the time any such
replacement shall become effective, the Borrower shall pay all unpaid fees
accrued for the account of the replaced Issuing Bank pursuant to Section
2.8(a)(iii). From and after the effective date the agreement of any Lender to be
an additional Issuing Bank and of any such replacement Issuing Bank, (i) such
additional Issuing Bank or successor Issuing Bank, as applicable, shall have all
the rights and obligations of an Issuing Bank under this Agreement with respect
to Letters of Credit to be issued by it thereafter and (ii) references herein to
the term "Issuing Bank" shall be deemed to include such successor Issuing Bank
or such additional Issuing Bank, as applicable, and all other or previous
Issuing Banks, as the context shall require. After the

                                       34
<PAGE>

replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain
a party hereto and shall continue to have all the rights and obligations of an
Issuing Bank under this Agreement with respect to Letters of Credit issued by it
prior to such replacement, but shall not be required to issue additional Letters
of Credit.

                  (j) Cash Collateralization. If any Event of Default shall
occur and be continuing, on the Business Day that the Borrower for whose account
the relevant Letter of Credit was issued receives notice from the Administrative
Agent or the Required Lenders (or, if the maturity of the Advances has been
accelerated, Lenders with LC Exposure representing greater than 66-2/3% of the
total LC Exposure) demanding the deposit of cash collateral pursuant to this
paragraph, such Borrower shall deposit in an account with the Administrative
Agent, in the name of the Administrative Agent and for the benefit of the
Lenders, an amount in cash equal to the LC Exposure as of such date plus any
accrued and unpaid interest thereon; provided that the obligation to deposit
such cash collateral shall become effective immediately, and such deposit shall
become immediately due and payable, without demand or other notice of any kind,
upon the occurrence of any Event of Default with respect to such Borrower
described in clauses (e) (ii) or (e) (iii) of Section 7.1. Such deposit shall be
held by the Administrative Agent in an interest bearing or investment account
(subject to investment as provided herein) as collateral for the payment and
performance of the obligations of such Borrower under this Agreement. The
Administrative Agent shall have exclusive dominion and control, including the
exclusive right of withdrawal, over such account. Investments of amounts on
deposit in such account shall be made at the option and sole discretion of the
Administrative Agent and at such Borrower's risk and expense. Interest, or
profits, if any, on any such investments, shall accumulate in such account.
Moneys in such account shall be applied by the Administrative Agent to reimburse
the Issuing Bank for LC Disbursements for which it has not been reimbursed and,
to the extent not so applied, shall be held for the satisfaction of the
reimbursement obligations of the Borrower for the LC Exposure at such time or,
if the maturity of the Advances has been accelerated (but subject to the consent
of Lenders with LC Exposure representing greater than 66-2/3% of the total LC
Exposure), be applied to satisfy other obligations of the Borrowers under this
Agreement. If a Borrower is required to provide an amount of cash collateral
hereunder as a result of the occurrence of an Event of Default, such amount (to
the extent not applied as aforesaid) shall be returned to such Borrower within
three Business Days after all Events of Default have been cured or waived.

                  SECTION 2.25. Replacement of Lenders, Issuing Banks, Etc. If
any Lender or any Issuing Bank requests compensation under Sections 2.12, 2.16
or 2.17 or if any Borrower is required to pay any additional amount to any
Lender or any Issuing Bank or any Governmental Authority for the account of any
Lender or any Issuing Bank pursuant to Section 2.20, or if any Lender suspends
the right of any Borrower to elect Eurodollar Rate Advances from such Lender
pursuant to Section 2.18, or if any Lender defaults in its obligation to fund
Advances hereunder, or any Issuing Bank defaults in its obligation to issue
Letters of Credit hereunder, then the Company may, at its sole expense and
effort, upon notice to such Lender or such Issuing Bank, as applicable, and the
Administrative Agent, in the case of an Issuing Bank, replace such Issuing Bank
in accordance with Section 2.24(i), or in the case of a Lender, require such
Lender to assign and delegate, without recourse (in accordance with and subject
to the restrictions contained in Section 9.7), all its interests, rights and
obligations under this Agreement (other than any outstanding CAF Advances held
by it) to an assignee that shall assume such obligations (which assignee may be
another Lender, if a Lender accepts such assignment); provided that (i) the
Company shall have received the prior written consent of the Administrative
Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall
have received payment of an amount equal to the outstanding principal of its
Advances (other than CAF Advances) and participations in LC Disbursements,
accrued interest thereon, accrued fees and all other amounts payable to it
hereunder, from the assignee (to the extent of such outstanding principal and
accrued interest and fees) or the Borrowers (in the case of all other amounts)
and (iii) in the case of any such assignment resulting from a claim for
compensation under Sections 2.12 , 2.16 or 2.17 or payments required to be made
pursuant to Section

                                       35

2.20, such assignment will result in a reduction in such compensation or
payments. A Lender or an Issuing Bank, as applicable, shall not be required to
make any such assignment and delegation if, prior thereto, as a result of a
waiver by such Lender or Issuing Bank, as applicable, or otherwise, the
circumstances entitling the Company to require such assignment and delegation
cease to apply.

         judgment of the Company be expected to result in a Material Adverse
         Effect.

         appropriate proceedings by the Company or the appropriate Subsidiary.

                  (i) The Company and each Principal Subsidiary have good title

         except that no representation or warranty is being made with respect to
         Margin Stock.

                  (j) No Termination Event has occurred or is reasonably
         expected to occur with respect to any Plan which, with the giving of

         under Section 7.1(g).

                  (k) Each Plan has complied with the applicable provisions of

         Multiemployer Plan which, when aggregated with all other amounts
         required to be paid to Multiemployer Plans in connection with
         Withdrawal Liability (as of the date of determination), would exceed
         10% of the Net Worth of the Company.

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

presentation required in Form 10-Q and 10-K, as appropriate, under the
Securities Exchange Act of 1934, as amended.

                  SECTION 5.4. Restrictions on Material Subsidiaries. The
Company will not, and will not permit any Material Subsidiary, to enter into any
agreement or understanding pursuant to which (a) any non-equity interest claim
the Company may have against any Material Subsidiary would be subordinate in any
manner to the payment of any other obligation of such Material Subsidiary (other
than waivers or subordination of subrogation, contribution or similar rights
under Guaranties and similar agreements) or (b) by its terms limits or restricts
the ability of such Material Subsidiary to make funds available to the Company
(whether by dividend or other distribution, by replacement of any inter-company
advance or otherwise) if, in any such case referred to in this Section 5.4,
there is, at the time any such agreement is entered into, a reasonable
likelihood that all such agreements and understandings, considered together,
would materially and adversely affect the ability of the Company to meet its
obligations as they become due.

                                   ARTICLE VI

                                   GUARANTEES

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

                  (b) Anything in this Article VI to the contrary
notwithstanding, the maximum liability of each Borrower (other than a Borrower
which is guaranteeing the Obligations of its Subsidiaries) under this Article VI
shall in no event exceed the amount which can be guaranteed by such Borrowing
Subsidiary under applicable federal and state laws relating to the insolvency of
debtors.

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

                  (d) No payment or payments made by any Borrower or any other
Person or received or collected by the Administrative Agent or any Lender from
any Borrower or any other Person by virtue of any action or proceeding or any
set-off or appropriation or application, at any time or from time to time, in
reduction of or in payment of the Obligations shall be deemed to modify, reduce,
release or otherwise affect the liability of the Borrowers under this Article VI
which shall, notwithstanding any such payment or payments, continue until the
Obligations are paid in full and the Commitments are terminated.

                  (e) Each Borrower agrees that whenever, at any time, or from
time to time, it shall make any payment to the Administrative Agent or any
Lender on account of its liability under this Article VI, it will notify the
Administrative Agent in writing that such payment is made under this Article VI
for such purpose.

                  SECTION 6.2. No Subrogation. Notwithstanding any payment or
payments made by any Borrower under this Article VI or any set-off or
application of funds of such Borrower by the Administrative Agent or any Lender,
such Borrower shall not be entitled to be subrogated to any of the

                                       47
<PAGE>

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

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

                  SECTION 6.4. Guarantee Absolute and Unconditional. Each
Borrower waives any and all notice of the creation, renewal, extension or
accrual of any of the Obligations and notice of or proof of reliance by the
Administrative Agent or any Lender upon this Agreement or acceptance of this
Agreement; the Obligations, and any of them, shall conclusively be deemed to
have been created, contracted or incurred, or renewed, extended, amended or
waived, in reliance upon this Agreement; and all dealings between any Borrower,
on the one hand, and the Administrative Agent and the Lenders, on the other,
shall likewise be conclusively presumed to have been had or consummated in
reliance upon this Agreement. Each Borrower waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon the
other Borrowers with respect to the Obligations. The guarantee contained in this
Article VI shall be construed as a continuing, absolute and unconditional
guarantee of payment without regard to (a) the validity, regularity or
enforceability of this Agreement, any Note, any of the Obligations or any other
collateral security therefor or guarantee or right of offset with respect
thereto at any time or from time to time held by the Administrative Agent or any
Lender, (b) any defense,

                                       48
<PAGE>

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

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

                                  ARTICLE VII

                                EVENTS OF DEFAULT

                  SECTION 7.1. Event of Default. If any of the following events
("Events of Default") shall occur and be continuing:

                  (a) Any Borrower shall fail to pay any installment of
         principal of any of its Advances or Notes or any reimbursement
         obligations in respect of any LC Disbursements when due, or any
         interest on any of its Advances or Notes or any other amount payable by
         it hereunder within five Business Days after the same shall be due; or

                  (b) Any representation or warranty made or deemed made by any
         Borrower herein or by any Borrower (or any of its officers) in
         connection with this Agreement shall prove to have been incorrect in
         any material respect when made or deemed made; or

                  (c) Any Borrower shall fail to perform or observe any other
         term, covenant or agreement contained in this Agreement on its part to
         be performed or observed and any such failure shall remain unremedied
         for 30 days after written notice thereof shall have been given to such

                                       49
<PAGE>

         Borrower by the Administrative Agent or by any Lender with a copy to
         the Administrative Agent; or

                  (d) The Company or any Principal Subsidiary shall fail to pay
         any Debt or Guaranty (excluding Debt incurred pursuant hereto) of the
         Company or such Principal Subsidiary in an aggregate principal amount
         of $200,000,000 or more, at such time, or any installment of principal
         thereof or interest or premium thereon, when due (whether by scheduled
         maturity, required prepayment, acceleration, demand or otherwise) and
         such failure shall continue after the applicable grace period, if any,
         specified in the agreement or instrument relating to such Debt or
         Guaranty; or any other default under any agreement or instrument
         relating to any such Debt, or any other event, shall occur and shall
         continue after the applicable grace period, if any, specified in such
         agreement or instrument, if the effect of such default or event is to
         accelerate the maturity of such Debt; or any such Debt shall be
         required to be prepaid (other than by a regularly scheduled required
         prepayment), prior to the stated maturity thereof, as a result of
         either (i) any default under any agreement or instrument relating to
         any such Debt or (ii) the occurrence of any other event (other than an
         issuance, sale or other disposition of stock or other assets, or an
         incurrence or issuance of Indebtedness or other obligations, giving
         rise to a repayment or prepayment obligation in respect of such Debt)
         the effect of which would otherwise be to accelerate the maturity of
         such Debt; provided that, notwithstanding any provision contained in
         this subsection (d) to the contrary, to the extent that pursuant to the
         terms of any agreement or instrument relating to any Debt or Guaranty
         referred to in this subsection (d) (or in the case of any such
         Guaranty, relating to any obligations Guaranteed thereby), any sale,
         pledge or disposal of Margin Stock, or utilization of the proceeds of
         such sale, pledge or disposal, would result in a breach of any covenant
         contained therein or otherwise give rise to a default or event of
         default thereunder and/or acceleration of the maturity of the Debt or
         obligations extended pursuant thereto, or payment pursuant to any
         Guaranty, and as a result of such terms or of such sale, pledge,
         disposal, utilization, breach, default, event of default or
         acceleration or nonpayment under such Guaranty, or the provisions
         thereof relating thereto, this Agreement or any Advance hereunder would
         otherwise be subject to the margin requirements or any other
         restriction under Regulation U issued by the Board of Governors of the
         Federal Reserve System, then such breach, default, event of default or
         acceleration, or nonpayment under any Guaranty, shall not constitute a
         default or Event of Default under this subsection (d); or

                  (e) (i) The Company or any Principal Subsidiary shall (A)
         generally not pay its debts as such debts become due; or (B) admit in
         writing its inability to pay its debts generally; or (C) make a general
         assignment for the benefit of creditors; or (ii) any proceeding shall
         be instituted or consented to by the Company or any Principal
         Subsidiary seeking to adjudicate it a bankrupt or insolvent, or seeking
         liquidation, winding up, reorganization, arrangement, adjustment,
         protection, relief, or composition of it or its debts under any law
         relating to bankruptcy, insolvency or reorganization or relief of
         debtors, or seeking the entry of an order for relief or the appointment
         of a receiver, trustee, or other similar official for it or for any
         substantial part of its property; or (iii) any such proceeding shall
         have been instituted against the Company or any Principal Subsidiary
         and either such proceeding shall not be stayed or dismissed for 60
         consecutive days or any of the actions referred to above sought in such
         proceeding (including the entry of an order for relief against it or
         the appointment of a receiver, trustee, custodian or other similar
         official for it or any substantial part of its property) shall occur;
         or (iv) the Company or any Principal Subsidiary shall take any
         corporate action to authorize any of the actions set forth above in
         this subsection (e); or

                  (f) Any judgment or order of any court for the payment of
         money in excess of $100,000,000 shall be rendered against the Company
         or any Principal Subsidiary and either

                                       50
<PAGE>

         (i) enforcement proceedings shall have been commenced and are
         continuing or have been completed by any creditor upon such judgment or
         order (other than any enforcement proceedings consisting of the mere
         obtaining and filing of a judgment lien or obtaining of a garnishment
         or similar order so long as no foreclosure, levy or similar process in
         respect of such lien, or payment over in respect of such garnishment or
         similar order, has commenced and is continuing or has been completed)
         or (ii) there shall be any period of 30 consecutive days during which a
         stay of execution or of enforcement proceedings (other than those
         referred to in the parenthesis in clause (i) above) in respect of such
         judgment or order, by reason of a pending appeal, bonding or otherwise,
         shall not be in effect; or

                  (g) (i) Any Termination Event with respect to a Plan shall
         have occurred and, 30 days after notice thereof shall have been given
         to the Company by the Administrative Agent, such Termination Event
         shall still exist; or (ii) the Company or any ERISA Affiliate shall
         have been notified by the sponsor of a Multiemployer Plan that it has
         incurred Withdrawal Liability to such Multiemployer Plan; or (iii) the
         Company or any ERISA Affiliate shall have been notified by the sponsor
         of a Multiemployer Plan that such Multiemployer Plan is in
         reorganization, or is insolvent or is being terminated, within the
         meaning of Title IV of ERISA; or (iv) any Person shall engage in a
         "prohibited transaction" (as defined in Section 406 of ERISA or Section
         4975 of the Code) involving any Plan; and in each case in clauses (i)
         through (iv) above, such event or condition, together with all other
         such events or conditions, if any, would result in an aggregate
         liability of the Company or any ERISA Affiliate that would exceed 10%
         of Net Worth; or

                  (h) Upon completion of, and pursuant to, a transaction, or a
         series of transactions (which may include prior acquisitions of capital
         stock of the Company in the open market or otherwise), involving a
         tender offer (i) a "person" (within the meaning of Section 13(d) of the
         Securities Exchange Act of 1934) other than the Company or a Subsidiary
         of the Company or any employee benefit plan maintained for employees of
         the Company and/or any of its Subsidiaries or the trustee therefor,
         shall have acquired direct or indirect ownership of and paid for in
         excess of 50% of the outstanding capital stock of the Company entitled
         to vote in elections for directors of the Company and (ii) at any time
         before the later of (A) six months after the completion of such tender
         offer and (B) the next annual meeting of the shareholders of the
         Company following the completion of such tender offer more than half of
         the directors of the Company consists of individuals who (1) were not
         directors before the completion of such tender offer and (2) were not
         appointed, elected or nominated by the Board of Directors in office
         prior to the completion of such tender offer (other than any such
         appointment, election or nomination required or agreed to in connection
         with, or as a result of, the completion of such tender offer); or

                  (i) Any event of default shall occur under any agreement or
         instrument relating to or evidencing any Debt now or hereafter existing
         of the Company or any Principal Subsidiary as the result of any change
         of control of the Company; or

                  (j) Any of the Guarantees contained in Article VI shall cease,
         for any reason, to be in full force and effect or any Borrower shall so
         assert; provided that if, within one Business Day after any Borrower
         receives notice from the Administrative Agent or otherwise becomes
         aware that such Guarantee is not in full force and effect, the Company
         delivers written notice to the Administrative Agent that the applicable
         Borrower intends to deliver a valid and effective Guarantee, or to
         reinstate such Guarantee, as soon as possible, then an Event of Default
         shall not exist pursuant this Section 7.1(j) unless the Company shall
         fail to deliver or reinstate or cause to be delivered or reinstated a
         Guarantee of the applicable Borrower having the same economic effect as
         the Guarantee set forth in Article VI within four Business Days after
         the delivery of such written notice of intent;

                                       51
<PAGE>

then, and in any such event, the Administrative Agent shall at the request, or
may with the consent, of the Majority Lenders, by notice to the Company, (i)
declare the obligation of each Lender to make Advances to be terminated,
whereupon the same shall forthwith terminate, and (ii) declare the Advances and
the Notes, all interest thereon and all other amounts payable under this
Agreement to be forthwith due and payable, whereupon the Advances and the Notes,
all such interest and all such amounts shall become and be forthwith due and
payable, without presentment, demand, protest or further notice of any kind, all
of which are hereby expressly waived by the Borrowers; provided, however, that
if an Event of Default under subsection (e) of this Section 7.1 (except under
clause (i)(A) thereof) shall occur, (A) the obligation of each Lender to make
Advances shall automatically be terminated and (B) the Advances and the Notes,
all interest thereon and all other amounts payable under this Agreement shall
automatically become and be forthwith due and payable, without presentment,
demand, protest or any notice of any kind, all of which are hereby expressly
waived by the Borrowers.

                                  ARTICLE VIII

               THE ADMINISTRATIVE AGENT AND THE CAF ADVANCE AGENT

                  SECTION 8.1. Authorization and Action. Each Lender and Issuing
Bank hereby appoints and authorizes the Administrative Agent and the CAF Advance
Agent to take such action as agent on its behalf and to exercise such powers
under this Agreement as are delegated to the Administrative Agent and the CAF
Advance Agent by the terms hereof, together with such powers as are reasonably
incidental thereto. As to any matters not expressly provided for by this
Agreement (including enforcement of this Agreement or collection of the Notes),
the Administrative Agent and the CAF Advance Agent shall not be required to
exercise any discretion or take any action, but shall be required to act or to
refrain from acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Majority Lenders, and such
instructions shall be binding upon all Lenders and all holders of Notes;
provided, however, that the Administrative Agent and the CAF Advance Agent shall
not be required to take any action which exposes the Administrative Agent or the
CAF Advance Agent to personal liability or which is contrary to this Agreement
or applicable law. The Administrative Agent and the CAF Advance Agent agree to
give to each Lender and Issuing Bank prompt notice of each notice given to it by
any Borrower pursuant to the terms of this Agreement.

                  SECTION 8.2. Administrative Agent's and CAF Advance Agent's
Reliance, Etc. None of the Administrative Agent, the CAF Advance Agent or any of
its respective directors, officers, agents or employees shall be liable for any
action taken or omitted to be taken by it or them under or in connection with
this Agreement, except for its or their own gross negligence or willful
misconduct. Without limitation of the generality of the foregoing, the
Administrative Agent and the CAF Advance Agent: (i) may treat the payee of any
Note as the holder thereof until the Administrative Agent receives and accepts
an Assignment and Acceptance entered into by the Lender which is the payee of
such Note, as assignor, and an Eligible Assignee, as assignee, as provided in
Section 9.7; (ii) may consult with legal counsel (including counsel for the
Company), independent public accountants and other experts selected by it and
shall not be liable for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such counsel, accountants or experts; (iii)

representations (whether written or oral) made in or in connection with this

performance or observance of any of the terms, covenants or conditions of this
Agreement on the part of the Borrowers or to inspect the property (including the

Agreement or any other instrument or document furnished pursuant hereto; and

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

                  SECTION 8.4. Lender Credit Decision. Each Lender and Issuing
Bank acknowledges that it has, independently and without reliance upon the
Administrative Agent, the CAF Advance Agent or any other Lender and based on the
financial statements referred to in Section 4.1 and such other documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender and Issuing Bank also
acknowledges that it will, independently and without reliance upon the
Administrative Agent, the CAF Advance Agent or any other Lender and based on
such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement.

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

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

                                       53
<PAGE>

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

                  SECTION 8.7. Syndication Agent; Co-Documentation Agents. None
of the Lenders identified on the cover page or signature pages or in the
preamble of this Agreement as a "syndication agent" or "co-documentation agent"
shall have any right, power, obligation, liability, responsibility or duty under
this Agreement other than those applicable to all Lenders as such. Without
limiting the foregoing, none of the Lenders so identified as a "syndication
agent" or "co-documentation agent" shall have or be deemed to have any fiduciary
relationship with any Lender. Each Lender acknowledges that it has not relied,
and will not rely, on any of the Lenders so identified in deciding to enter into
this Agreement or in taking or not taking action hereunder.

                                   ARTICLE IX

                                  MISCELLANEOUS

                  SECTION 9.1. Amendments, Etc. An amendment or waiver of any
provision of this Agreement or the Notes, or a consent to any departure by any
Borrower therefrom, shall be effective against the Lenders and all holders of
the Notes if, but only if, it shall be in writing and signed or consented to in
writing by the Majority Lenders, and then such a waiver or consent shall be
effective only in the specific instance and for the specific purpose for which
given; provided, however, that no such amendment, waiver or consent shall,
unless in writing and signed by all the Lenders, be effective to: (a) waive any
of the conditions specified in Article III, (b) except as contemplated by
Sections 2.4, 2.5, 2.23, 2.24(b) and 2.25, increase or extend the Commitments of

Agent and the CAF Advance Agent in addition to the Lenders required hereinabove
to take such action, affect the rights or duties of the Administrative Agent or
the CAF Advance Agent under this Agreement or any Note; provided, still further,
that the guarantee of a Borrower under Article VI shall be released
automatically upon (i) the sale by the Company of such Borrower, provided that
such sale is permitted

                                       54
<PAGE>

under this Agreement, or (ii) such Borrower ceasing to be a Borrower (it being
understood that the Company and EPNGC shall never cease to be a Borrower
hereunder).

                  SECTION 9.2. Notices, Etc. Except as otherwise provided in
Section 2.2(a), 2.5(d) or 2.15(b), all notices and other communications provided

connection with this Agreement. All such notices and communications shall, if so
mailed, telecopied or otherwise transmitted, be effective when received, if
mailed, or when the appropriate answerback or other evidence of receipt is
given, if telecopied or otherwise transmitted, respectively. A notice received
by the Administrative Agent, the CAF Advance Agent, an Issuing Bank or a Lender
by telephone pursuant to Section 2.2(a), 2.5(d) or 2.15(a) shall be effective if
the Administrative Agent, Issuing Bank or Lender believes in good faith that it

pursuant thereto, notwithstanding the absence of written confirmation or any
contradictory provision thereof. Notices and other communications to the Lenders
or any Issuing Bank hereunder may be delivered or furnished by email
communications pursuant to procedures approved by the Administrative Agent;
provided that the forgoing shall not apply to notices pursuant to Article II
unless otherwise agreed by the Administrative Agent and the applicable Lender or
Issuing Bank. The Administrative Agent or any Borrower each may, in its
discretion, agree to accept notices and other communications to it hereunder by
email communications pursuant to procedures approved by it; provided that
approval of such procedures may be limited to particular notices or
communications.

                  SECTION 9.3. No Waiver; Remedies. No failure on the part of
any Lender, any Issuing Bank, the Administrative Agent or the CAF Advance Agent
to exercise, and no delay in exercising, any right hereunder or under any Note
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right hereunder or under any Note preclude any other or further exercise
thereof or the exercise of any other right. The remedies herein provided are
cumulative and not exclusive of any remedies provided by law.

                  SECTION 9.4. Costs and Expenses; Indemnity. (a) Each
Borrower agrees to pay on demand (to the extent not reimbursed by any other
Borrower) (i) all reasonable fees and out-of-pocket expenses of counsel for the
Administrative Agent in connection with the preparation, execution and delivery
of this Agreement, the Notes and the other documents to be delivered hereunder
and the fulfillment or attempted fulfillment of conditions precedent hereunder,
(ii) all reasonable costs and expenses incurred by the Administrative Agent and
its Affiliates in initially syndicating all or any portion of the Commitments

of Credit and the other documents to be delivered hereunder and thereunder,

                                       55
<PAGE>

including the reasonable fees and out-of-pocket expenses of counsel and all such
out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of this Agreement or the Letters of Credit, and (iv) all
reasonable out-of-pocket expenses incurred by an Issuing Bank in connection with
the issuance, amendment, renewal or extension of any Letter of Credit.

                  (b) If any payment of principal of, or Conversion of, any
Eurodollar Rate Advance or CAF Advance is made by any Borrower to or for the
account of a Lender on any day other than the last day of the Interest Period
for such Advance, as a result of a prepayment pursuant to Section 2.15 or a
Conversion pursuant to Section 2.13(f) or Section 2.14 or due to acceleration of
the maturity of the Advances and the Notes pursuant to Section 7.1 or due to any
other reason attributable to such Borrower, or if any Borrower shall fail to
make a borrowing of Eurodollar Rate Advances or CAF Advances after such Borrower
has given a notice requesting the same in accordance with the provisions of this
Agreement, such Borrower shall, upon demand by such Lender (with a copy of such
demand to the Administrative Agent), pay to the Administrative Agent for the
account of such Lender any amounts required to compensate such Lender for any
additional losses, costs or expenses which it may reasonably incur as a result
of such payment, Conversion or failure to borrow, including any loss (excluding
loss of anticipated profits), cost or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by any Lender to
fund or maintain such Advance.

                  (c) Each Borrower agrees to indemnify and hold harmless the
Administrative Agent, the CAF Advance Agent, each Issuing Bank and each Lender
(to the extent not reimbursed by any other Borrower) from and against any and
all claims, damages, liabilities and expenses (including fees and disbursements
of counsel) which may be incurred by or asserted against the Administrative
Agent, the CAF Advance Agent, such Issuing Bank or such Lender in connection
with or arising out of any investigation, litigation, or proceeding (whether or
not the Administrative Agent, the CAF Advance Agent, such Issuing Bank or such
Lender is party thereto) related to any acquisition or proposed acquisition by
the Company, or by any Subsidiary of the Company, of all or any portion of the
stock or substantially all the assets of any Person or any use or proposed use
of the Advances by any Borrower (excluding any claims, damages, liabilities or
expenses incurred by reason of the gross negligence or willful misconduct of the
party to be indemnified or its employees or agents, or by reason of any use or
disclosure of information relating to any such acquisition or use or proposed
use of the proceeds by the party to be indemnified or its employees or agents).

                  SECTION 9.5. Right of Set-Off. Upon the declaration of the
Advances and the Notes as due and payable pursuant to the provisions of Section
7.1, each Lender is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender to or for the credit or the
account of the applicable Borrower against any and all of the obligations of
such Borrower now or hereafter existing under this Agreement and the Notes of
such Borrower held by such Lender, irrespective of whether or not such Lender
shall have made any demand under this Agreement or such Notes and although such
obligations may be unmatured. Each Lender agrees promptly to notify the Company
after any such set-off and application made by such Lender, provided that the
failure to give such notice shall not affect the validity of such set-off and
application. The rights of each Lender under this Section 9.5 are in addition to
other rights and remedies (including other rights of set-off) which such Lender
may have.

                  SECTION 9.6. Binding Effect. This Agreement shall become
effective in accordance with the provisions of Section 3.1, and thereafter shall
be binding upon and inure to the benefit of the Borrowers, the Administrative
Agent, the CAF Advance Agent, each Issuing Bank and each Lender and their
respective successors and assigns (including any Affiliate of an Issuing Bank
that issues any Letter of Credit), except that no Borrower shall have the right
to assign its rights or obligations hereunder or any

                                       56
<PAGE>

interest herein in a transaction not permitted by Section 5.2(e) without the
prior written consent of all of the Lenders.

                  SECTION 9.7. Assignments and Participations. (a) Each
Lender may assign to one or more banks or other financial institutions all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment, the Advances owing to it and the Notes held by it);
provided, however, that (i) each such assignment shall be of a constant, and not
a varying, percentage of all such Lender's rights and obligations under this
Agreement, (ii) the amount of the Commitment of the assigning Lender being
assigned to an assignee pursuant to each such assignment (determined as of the
date of the Assignment and Acceptance with respect to such assignment) shall in
no event be less than $15,000,000 (or, if less, the entire Commitment of the
assigning Lender) and shall be an integral multiple of $1,000,000, (iii) each
such assignment shall be to an Eligible Assignee, and (iv) the parties to each
such assignment shall execute and deliver to the Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance, together
with any Notes subject to such assignment and a processing and recordation fee
of $2,500, and shall send to the Company an executed counterpart of such
Assignment and Acceptance. Upon such execution, delivery, acceptance and
recording, from and after the effective date specified in each Assignment and
Acceptance, (A) the assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, have the rights and obligations of a Lender
hereunder and (B) the assigning Lender thereunder shall, to the extent that
rights and obligations hereunder have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights and be released from its
obligations under this Agreement (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under this Agreement, such Lender shall cease to be a party
hereto).

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

                  (c) The Administrative Agent shall maintain at its address
referred to in Section 9.2 a copy of each Assignment and Acceptance delivered to
and accepted by it and a register (which register may be in electronic form) for
the recordation of the names and addresses of the Lenders and the Commitment of,
and principal amount of the Advances and LC Disbursements owing to, each Lender
from time to time (the "Register"). The entries in the Register shall be
conclusive and binding for all purposes, absent manifest error, and each
Borrower, the Administrative Agent, the CAF Advance Agent, each Issuing Bank and
the Lenders may treat each Person whose name is recorded in the Register as a
Lender hereunder for all purposes of this Agreement. The Register shall be
available for inspection by any Borrower, any Issuing Bank or any Lender at any
reasonable time and from time to time upon reasonable prior notice. Upon the
acceptance of any Assignment and Acceptance for recordation in the Register,
Schedule I hereto shall be deemed to be amended to reflect the revised
Commitments of the Lenders parties to such Assignment and Acceptance and if any
new assignee under this Section 9.7 shall not be a Lender at the time of the
assignment it also shall deliver to the Administrative Agent an Administrative
Questionnaire.

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

                  (e) Each Lender may sell participations to one or more banks
or other entities in or to all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment, and the Advances
owing to it and the Notes held by it); provided, however, that (i) such Lender's
obligations under this Agreement (including its Commitment to the Borrowers
hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Notes for all purposes of
this Agreement, (iv) the Borrowers, the Administrative Agent, the CAF Advance
Agent, each Issuing Bank and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, (v) such Lender shall continue to be able to
agree to any modification or amendment of this Agreement or any waiver hereunder
without the consent, approval or vote of any such participant or group of
participants, other than modifications, amendments and waivers which (A)
postpone any date fixed for any payment of, or reduce any payment of, principal
of or interest on such Lender's Advances or Notes or any facility fees payable
under this Agreement, or (B) increase the amount of such Lender's Commitment in
a manner which would have the effect of increasing the amount of a participant's
participation, or (C) reduce the interest rate payable under this Agreement and
such Lender's Notes, or (D) consent to the assignment or the transfer by any
Borrower of any of its rights and obligations under the Agreement, and (vi)
except as contemplated by the immediately preceding clause (v), no participant
shall be deemed to be or to have any of the rights or obligations of a "Lender"
hereunder.

<PAGE>

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

                  (g) Anything in this Agreement to the contrary
notwithstanding, any Lender may at any time create a security interest in all or
any portion of its rights under this Agreement (including the Advances owing to
it) and the Notes issued to it hereunder in favor of any Federal Reserve Bank in
accordance with Regulation A of the Board of Governors of the Federal Reserve
System (or any successor regulation) and the applicable operating circular of
such Federal Reserve Bank.

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

                  SECTION 9.9. Consent to Jurisdiction. (a) Each Borrower
hereby irrevocably submits to the jurisdiction of any New York State or Federal
court sitting in New York City and any appellate court from any thereof in any
action or proceeding by the Administrative Agent, the CAF Advance Agent, any
Lender, any Issuing Bank or the holder of any Note in respect of, but only in
respect of, any claims or causes of action arising out of or relating to this
Agreement or the Notes (such claims and causes of action, collectively, being
"Permitted Claims"), and each Borrower hereby irrevocably agrees that all
Permitted Claims may be heard and determined in such New York State court or in
such Federal court. Each Borrower hereby irrevocably waives, to the fullest
extent it may effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any aforementioned court in respect
of Permitted Claims. Each Borrower hereby irrevocably appoints CT Corporation
System (the "Process Agent"), with an office on the date hereof at 111 Eighth
Avenue, 13th Floor, New York, New York 10011, as its agent to receive on behalf
of such Borrower and its property service of copies of the summons and complaint
and any other process which may be served by the Administrative Agent, any
Lender or the holder of any Note in any such action or proceeding in any
aforementioned court in respect of Permitted Claims. Such service may be made by
delivering a copy of such process to the Company by courier and by certified

to Section 9.2, and each Borrower hereby irrevocably authorizes and directs the
Process Agent to accept such service on its behalf. Each Borrower agrees that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.

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

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

                  SECTION 9.11. Rate of Interest. It is the intention of the
parties hereto that each Lender shall each conform strictly to usury laws
applicable to it. Accordingly, if the transactions contemplated hereby would be
usurious as to any Lender under laws applicable to it, then, in that event,
notwithstanding anything to the contrary in this Agreement or in the Notes to
the order of such Lender, it is agreed as follows: (a) the aggregate of all
consideration which constitutes interest under law applicable to such Lender
that is contracted for, taken, reserved, charged or received by such Lender
hereunder, or under such Notes or otherwise, shall under no circumstances exceed
the maximum amount allowed by such applicable law, and any excess shall be
credited by such Lender on the principal amount of the sums owed to such Lender
(or, if all amounts owing to such Lender shall have been paid in full, refunded
by such Lender to the applicable Borrower); or (b) in the event that a
prepayment of any Advances owed to any Lender is required, then such
consideration that constitutes interest under law applicable to such Lender may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for shall be cancelled automatically by such
Lender as of the date of such prepayment and, if theretofore paid, shall be
credited by such Lender on the principal amount of such prepayment obligation
(or, if the principal amount of such prepayment obligation shall have been paid
in full, refunded by such Lender to the applicable Borrower). To the extent that
Article 5069-1.0001 of the Texas Revised Civil Statutes is relevant to any
Lender for the purpose of determining the maximum amount of interest allowed by
applicable law, such Lender hereby elects to determine the applicable rate
ceiling under such Article by the indicated (weekly) rate ceiling from time to
time in effect, subject to such Lender's right subsequently to change such
method in accordance with applicable law. In no event, however, shall Chapter
346 of the Texas Finance Code apply to this Agreement or the Notes or the
transactions contemplated hereby.

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

                  SECTION 9.13. Continuing Effect. The Original Agreement, as
amended and restated hereby, continues in full force and effect as so amended
and restated.

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

                             Re: El Paso Corporation

Ladies and Gentlemen:

                  This opinion is furnished to you pursuant to Section
3.2(b)(iii) of the Amended and Restated $1,000,000,000 3-Year Revolving Credit
and Competitive Advance Facility Agreement, dated as of June 27, 2002 (the
"Credit Agreement"), among El Paso Corporation (the "Company"), El Paso Natural
Gas Company ("EPNGC"), Tennessee Gas Pipeline Company ("Tennessee"), El Paso CGP
Company ("CGP") (CGP, together with the Company, EPNGC and Tennessee, the
"Borrowers"), the banks and other financial institutions from time to time party
thereto (each a "Lender", and together the "Lenders"), JPMorgan Chase Bank, as
Administrative Agent (in such capacity, the "Administrative Agent"), as CAF
Advance Agent (in such capacity, the "CAF Advance Agent") for the Lenders, and
as Issuing Bank, Citibank and ABN AMRO Bank N.V., as Co-Documentation Agents (in
such capacity, the "Co-Documentation Agents") , and Bank of America, N.A., as
Syndication Agent (in such capacity, the "Syndication Agent"). Unless the
context otherwise requires, all capitalized terms used herein without definition
shall have the meanings ascribed to them in the Credit Agreement.

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

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

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

                  (3) the other documents furnished by the Borrowers pursuant to
Sections 3.1 and 3.2 of the Credit Agreement.

                  I, or attorneys over whom I exercise supervision, have also
examined the originals, or copies certified to our satisfaction, of the
agreements, instruments and other documents, and all of the orders, writs,
judgments, awards, injunctions and decrees, which affect or purport to affect
the Borrowers' ability to perform their respective obligations under the Credit
Agreement or the Notes (collectively referred to herein as the "Documents"). In
addition, I, or attorneys over whom I exercise supervision, have examined the
originals, or copies certified to our satisfaction, of such other corporate
records of the Borrowers, certificates of public officials and of officers of
the Borrowers, and agreements, instruments

                                      G-1
<PAGE>

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

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

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

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

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

                  2. The execution, delivery and performance by each Borrower of
         the Documents to which it is a party are within such Borrower's
         corporate powers and have been duly authorized by all necessary
         corporate action in respect of or by such Borrower, and do not
         contravene (i) such Borrower's charter or by-laws, each as amended to
         date, (ii) any federal law, rule or regulation applicable to such
         Borrower (excluding provisions of federal law expressly referred to in
         and covered by the opinion of Jones, Day, Reavis & Pogue delivered to
         you in connection with the transactions contemplated hereby) or any
         provision of the General Corporation Law of the State of Delaware
         applicable to such Borrower, or (iii) any contractual restriction
         binding on or affecting such Borrower. The Documents to which it is a
         party have been duly executed and delivered on behalf of each Borrower.

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

                  4. To the best of my knowledge, there is no action, suit or
         proceeding pending or overtly threatened against or involving the
         Company or any of the Principal Subsidiaries which, in my reasonable
         judgment (taking into account the exhaustion of all appeals), would
         have a material adverse effect upon the consolidated financial
         condition of the Company and its

                                      G-2
<PAGE>

         consolidated Subsidiaries taken as a whole, or which purports to affect
         the legality, validity, binding effect or enforceability of any
         Document.

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

                                                     Very truly yours,

                  Re:   Amended and Restated $1,000,000,000 3-Year Revolving
                        Credit and Competitive Advance Facility Agreement
                        dated as of June 27, 2002

Dear Ladies and Gentlemen:

                  We have acted as special New York counsel for El Paso
Corporation, a Delaware corporation (the "Company"), El Paso Natural Gas
Company, a Delaware corporation ("EPNGC") and Tennessee Gas Pipeline Company, a
Delaware corporation ("Tennessee"), El Paso CGP Company ("CGP") (CGP together
with the Company, EPNGC and Tennessee, the "Borrowers"), in connection with the
Amended and Restated $1,000,000,000 3-Year Revolving Credit and Competitive
Advance Facility Agreement, dated as of June 27, 2002 (the "Financing
Agreement"), among the Company, EPNGC, Tennessee, CGP, the banks and other
financial institutions from time to time party thereto (each a "Lender", and
together the "Lenders"), JPMorgan Chase Bank, as administrative agent (in such
capacity, the "Administrative Agent"), as CAF Advance Agent (in such capacity,
the "CAF Advance Agent") for the Lenders, and as Issuing Bank, Citibank, N.A.
and ABN AMRO Bank N.V., as Co-Documentation Agents (in such capacity, the
Co-Documentation Agents"), and Bank of America, N.A., as Syndication Agent (in
such capacity, the "Syndication Agent"). This opinion is delivered to you
pursuant to Section 3.2(b)(iv) of the Financing Agreement. Capitalized terms
used herein and not otherwise defined have the meanings assigned such terms in
the Financing Agreement. With your permission, all assumptions and statements of
reliance herein have been made without any independent investigation or
verification on our part except to the extent otherwise expressly stated, and we
express no opinion with respect to the subject matter or accuracy of the
assumptions or items upon which we have relied.

                  In connection with the opinions expressed herein, we have
examined such documents, records and matters of law as we have deemed necessary
for the purposes of this opinion. We have examined, among other documents, the
following:

                  (a) An executed copy of the Financing Agreement; and

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

The documents referred to in items (a) and (b) above are referred to herein
collectively as the "Documents."

                                      H-1
<PAGE>

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

                  To the extent it may be relevant to the opinions expressed
herein, we have assumed that the parties to the Documents have the power to
enter into and perform such documents and to consummate the transactions
contemplated thereby and that such documents have been duly authorized, executed
and delivered by, and, except as set forth in paragraph (b) with respect to the
Borrowers, constitute legal, valid and binding obligations of, such parties.

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

                  (a) The execution and delivery to the Administrative Agent,
the CAF Advance Agent, the Co-Documentation Agents, the Syndication Agent, the
Issuing Bank and the Lenders by each Borrower of the Documents to which it is a
party and the performance by each Borrower of its obligations thereunder (i) do
not require under present law any filing or registration by such Borrower with,
or approval or consent to such Borrower of, any governmental agency or authority
of the State of New York that has not been made or obtained except those
required in the ordinary course of business in connection with the performance
by such Borrower of its obligations under certain covenants and warranties
contained in the Documents to which it is a party and (ii) do not violate any
present law, or present regulation of any governmental agency or authority, of
the State of New York applicable to such Borrower or its property.

                  (b) The Documents to which it is a party constitute legal,
valid and binding obligations of each Borrower enforceable against such Borrower
in accordance with their respective terms.

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

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

         (A)      We express no opinion as to:

                  (i) the validity, binding effect or enforceability (a) of any
         provision of the Documents relating to indemnification, contribution or
         exculpation in connection with violations of any securities laws or
         statutory duties or public policy, or in connection with willful,
         reckless or criminal acts or gross negligence of the indemnified or
         exculpated party or the party receiving contribution; or (b) of any
         provision of any of the Documents relating to exculpation of any party

                                      H-2
<PAGE>

         in connection with its own negligence that a court would determine in
         the circumstances under applicable law to be unfair or insufficiently
         explicit;

                  (ii) the validity, binding effect or enforceability of (a) any
         purported waiver, release, variation, disclaimer, consent or other
         agreement to similar effect (all of the foregoing, collectively, a
         "Waiver") by the Borrowers under the Documents to the extent limited by
         provisions of applicable law (including judicial decisions), or to the
         extent that such a Waiver applies to a right, claim, duty, defense or
         ground for discharge otherwise existing or occurring as a matter of law
         (including judicial decisions), except to the extent that such a Waiver
         is effective under and is not prohibited by or void or invalid under
         provisions of applicable law (including judicial decisions), (b) any
         provision of any Document relating to choice of governing law to the
         extent that the validity, binding effect or enforceability of any such
         provision is to be determined by any court other than a court of the
         State of New York or (c) any provision of any Document relating to
         forum selection to the extent the forum is a federal court;

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

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

                  (v) any approval, consent or authorization of the Federal
         Energy Regulatory Commission or any other United States federal agency
         or authority needed in connection with the execution, delivery and
         performance by any Borrower of the Documents to which it is a party,
         the consummation of the transactions contemplated thereby and
         compliance with the terms and conditions thereof.

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

         (C) Our opinions as to enforceability are subject to the effect of
generally applicable rules of law that:

                  (i) limit the availability of a remedy under certain
         circumstances when another remedy has been elected; and

                                      H-3
<PAGE>

                  (ii) may, where less than all of a contract may be
         unenforceable, limit the enforceability of the balance of the contract
         to circumstances in which the unenforceable portion is not an essential
         part of the agreed exchange; and

                  (iii) govern and afford judicial discretion regarding the
         determination of damages and entitlement to attorneys' fees and other
         costs.

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

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

                  The opinions expressed herein are limited to the federal laws
of the United States of America (in the case of the matters covered in paragraph
(c) above) and the laws of the State of New York, as currently in effect, except
that we express no opinion with respect to laws, rules or regulations of the
State of New York, or of any governmental agency or authority thereof,
applicable to companies engaged in the gathering, processing, transmission,
distribution or marketing of natural gas or other hydrocarbon derivatives or
power generation or the generation, transmission, distribution or marketing of
electricity, or as to filings, registrations, approvals or consents under or by
such laws, rules or regulations.

                  We express no opinion as to the compliance or noncompliance,
or the effect of the compliance or noncompliance, of each of the addressees with
any state or federal laws or regulations applicable to each of them by reason of
their status as or affiliation with a federally insured depository institution.

                  The opinions expressed herein are solely for the benefit of
the Administrative Agent, CAF Advance Agent, the Issuing Bank, the
Co-Documentation Agents, the Syndication Agent and the Lenders and may not be
relied on in any manner or for any purpose by any other person or entity.

                     FORM OF OPINION OF [ASSOCIATE GENERAL]
                         [SENIOR] COUNSEL OF THE COMPANY

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

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

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

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

         the Syndication Agent and the Lenders by the Company and the Borrowing
         Subsidiary of the Joinder Agreement and by the Borrowing Subsidiary of
         the Notes made by it and the performance by the Borrowing Subsidiary of
         its obligations as a "Borrower" under the Credit Agreement and the
         Notes made by it (i) do not require under present law any filing or
         registration by the Company or the Borrowing Subsidiary with, or
         approval or consent to the Company or the Borrowing Subsidiary of, any
         governmental agency or authority of the State of New York that has not
         been made or obtained, except those, if any, required in the ordinary
         course of business in connection with the performance by the Company or
         the Borrowing Subsidiary of their respective obligations under certain
         covenants and warranties contained in the Joinder Agreement, the Credit
         Agreement and the Notes and (ii) do not violate any present law, or
         present regulation of any governmental agency or authority, of the
         State of New York applicable to the Company or the Borrowing Subsidiary
         or its respective property.

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

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