operate the Acquired Partnership Restricted Business and the Competitive Services customers
of the Acquired Partnership Restricted Business at the time of the consummation of such

10

 

acquisition shall no longer be UCH Customers for purposes of this Agreement, but rather

as, an “Acquiring Party”), the Acquiring Party shall notify in writing (x) the Partnership,
if the Acquiring Party is a UCH Entity or (y) UCH, if the Acquiring Party is a Partnership
Entity, of such acquisition. The Person that is so notified shall be referred to herein as
the “Offeree.” Such notice shall include an offer (the “Offer”) by the Acquiring Party to
sell the Acquired UCH Restricted Business or the Acquired Partnership Restricted Business,
as the case may be (the “Offered Assets”), to the Offeree, together with a proposed
definitive agreement to effectuate the purchase and sale of the Offered Assets (the
“Purchase Agreement”). The Offer shall set forth the Acquiring Party’s proposed terms
relating to the sale of the Offered Assets to the Offeree, including the purchase price, any
liabilities to be assumed by the Offeree as part of the Offer and the other terms of the
Offer; provided, that the representations and warranties regarding the Offered Assets and
the indemnification provision contained in the Purchase Agreement shall be substantially
consistent with the terms contained in the definitive purchase agreement pursuant to which
the Acquiring Party acquired the Offered Assets or the entity that owned the Offered Assets,
subject to such adjustments that the Acquiring Party reasonably determines are necessary to
reflect the differences in the transaction.

     (b) As soon as practicable after the Offer is made, the Acquiring Party will deliver to
the Offeree all information prepared by or on behalf of or in the possession of such
Acquiring Party relating to the Offered Assets and reasonably requested by the Offeree. As
soon as practicable, but in any event, within 60 days after receipt of the notification
called for in Section 2.4(a), the Offeree shall notify the Acquiring Party in writing that
either:

     (i) the Offeree (with the concurrence of the Conflicts Committee if the Offeree
is the Partnership) has elected not to purchase (or not to cause any of its
Subsidiaries to purchase) any of such Offered Assets; or

     (ii) the Offeree (with the concurrence of the Conflicts Committee if the
Offeree is the Partnership) has elected to purchase (or to cause any of its
Subsidiaries to purchase) all of such Offered Assets; provided, that if the Offeree
is the Partnership, and in the opinion of outside counsel to the Partnership

11

 

Entities, less than 90% of the gross income from the operations of such Offered
Assets consists of “qualifying income” under Section 7704 of the Code (such portion
of such Offered Assets that does not so qualify being referred to herein as the
“Non-Qualifying Business”), then the Partnership (with the concurrence of the
Conflicts Committee) may condition its obligation to purchase the Non-Qualifying
Business (but not the portion of the Offered Assets that do not constitute the
Non-Qualifying Business (the “Qualifying Business”)) on the conversion of the
agreements pursuant to which the Non-Qualifying Business provides Competitive
Services to its customers to agreements substantively similar to the Form
Compression Services Agreement from a federal income tax treatment perspective (from
the Partnership’s perspective) and otherwise having substantially the same economic
terms as the agreements being converted (the “Conversion Condition”); provided
further, that in such event, each of the UCH Entities and the Partnership Entities
shall use commercially reasonable efforts to satisfy the Conversion Condition as
soon as commercially practicable. If the Offeree elects to purchase the Offered
Assets, the following procedures shall be followed:

     A. After the receipt of the Offer by the Offeree, the Acquiring Party
and the Offeree shall negotiate in good faith the fair market value of the
Offered Assets that are subject to the Offer (including the specific fair
market value of any Offered Assets that constitute a Non-Qualifying
Business) and the other terms of the Offer on which the Offered Assets will
be sold to the Offeree. If the Acquiring Party and the Offeree agree (with
the concurrence of the Conflicts Committee) on the fair market value of the
Offered Assets that are subject to the Offer and the other terms of the
Offer during the 30-day period (the “Offer Period”) after receipt by the
Acquiring Party of the Offeree’s election to purchase (or to cause any
Subsidiary of the Offeree to purchase) the Offered Assets, the Offeree shall
purchase (or cause any of its Subsidiaries to purchase) and the Acquiring
Party shall sell the Offered Assets on such terms as soon as commercially
practicable after such agreement has been reached, which obligation may
require such parties to consummate the purchase and sale of the Qualifying
Business prior to satisfaction of the Conversion Condition.

     B. If the Acquiring Party and the Offeree are unable to agree on the
fair market value of the Offered Assets that are subject to the Offer or on
any other terms of the Offer during the Offer Period, the Acquiring Party
and the Offeree will engage an independent investment banking firm prior to
the end of the Offer Period to determine the fair market value of the
Offered Assets (including the specific fair market value of any Offered
Assets that constitute a Non-Qualifying Business) and/or the other terms
on which the Acquiring Party and the Offeree are unable to agree. In
determining the fair market value and other terms on which the Offered
Assets are to be sold, the investment banking firm will have access to the
proposed sale and purchase values and terms for the Offer submitted by

12

 

the Acquiring Party and the Offeree, respectively, and to all information
prepared by or on behalf of the Acquiring Party relating to the Offered
Assets and reasonably requested by the investment banking firm. In
determining the terms on which the Offered Assets are to be sold (other than
the fair market value of the Offered Assets), the investment banking firm
shall give substantial weight to the terms contained in the definitive
purchase agreement pursuant to which the Acquiring Party acquired the
Offered Assets or the entity that owned the Offered Assets. Such investment
banking firm will determine the fair market value of the Offered Assets
and/or the other terms on which the Acquiring Party and the Offeree are
unable to agree within 60 days of its engagement and furnish the Acquiring
Party and the Offeree its determination. The fees and expenses of the
investment banking firm will be divided equally between the Acquiring Party
and the Offeree. Upon receipt of such determination, the Offeree will have
the option, but not the obligation, to (with the concurrence of the
Conflicts Committee if the Offeree is the Partnership):

     1. purchase the Offered Assets on such terms as determined
above; or

     2. elect not to purchase such Offered Assets.

If the Offeree elects to so purchase the Offered Assets, the Offeree shall
purchase (or cause any of its Subsidiaries to purchase) and the Acquiring
Party shall sell the Offered Assets on such terms as soon as commercially
practicable after such agreement has been reached, which obligation may
require such parties to consummate the purchase and sale of the Qualifying
Business prior to satisfaction of the Conversion Condition.

     2.5 Scope of the Prohibition. Except as provided in this Article II, each of the Parties
shall be free to engage (whether directly or through the acquisition of or investment in equity or
debt interests in any Person) in any business activity whatsoever, including those that may be in
direct competition with any of the other Parties.

     2.6 New Customers. The Parties agree that any offer by any of the Parties hereto to provide
Competitive Services to New Customers in any state or territory of the United States shall be first
made on behalf of the Partnership Entities and shall include an offer to provide such Competitive
Services under an agreement substantially in the form of the Form Compression Services Agreement.
If the New Customer is unwilling to enter into an agreement with a Partnership Entity that is substantively similar to the
Form Compression Services Agreement from a federal income tax treatment perspective (from the Partnership’s perspective), a UCH
Entity may enter into an agreement to provide Competitive Services to such New Customer for its own account provided that any
agreement between such UCH Entity and such New Customer is not substantively similar to the Form Compression Services Agreement
from a federal income tax treatment perspective (from the Partnership’s perspective). If a New Customer enters into an agreement
with a member of the Partnership Group for Competitive Services, then such New

13

 

Customer will then constitute a
Partnership Customer for the purposes of this Agreement and if, in accordance with this Section
2.6, a New Customer enters into an agreement with a UCH Entity for Competitive Services, then such
New Customer will then constitute a UCH Customer for the purposes of this Agreement.

     2.7 Enforcement. Each Party agrees and acknowledges that the other Parties hereto do not have
an adequate remedy at law for the breach by such Party of the covenants and agreements set forth in
this Article II, and that any breach by such Party of the covenants and agreements set forth in
this Article II would result in irreparable harm to the other Parties hereto. Each Party further
agrees and acknowledges that the other Parties hereto may, in addition to the other remedies that
may be available to the other Parties hereto, file a suit in equity to enjoin such Party from such
breach, and consents to the issuance of injunctive relief under this Agreement.

     2.8 Termination. Unless this Agreement has otherwise terminated pursuant to Section 8.4, this
Article II shall terminate on the third anniversary of the Closing Date. In addition, unless this
Agreement has otherwise been terminated pursuant to Section 8.4 or this Article II has otherwise
been terminated pursuant to the first sentence of this Section 2.8, Sections 2.1, 2.2, 2.3, 2.4 and
2.6 shall terminate upon a Change of Control of UCH. Unless this Agreement has otherwise
terminated pursuant to Section 8.4 or this Article II has terminated pursuant to the first sentence
of this Section 2.8, and in the event that Sections 2.1, 2.2, 2.3, 2.4 and 2.6 terminate pursuant
to the immediately preceding sentence, without the prior written approval of the Conflicts
Committee, the UCH Entities shall be prohibited from providing (whether directly or through the
acquisition of or investment in equity or debt securities of any Person) Competitive Services to a
particular Partnership Customer at the particular Site at which the Partnership Group was providing
Competitive Services to such Partnership Customer on the date of the Change of Control of UCH.

ARTICLE III

SERVICES

     3.1 Provision, Allocation and Reimbursement for Services

     (a) Subject to Article V, the UCH Entities shall, upon the reasonable request of the
General Partner, provide the Partnership Group with all personnel and services
reasonably necessary to run the business of the Partnership Group, which services may
include, without limitation, those services set forth on Schedule 3.1(a)
(collectively, the “Services”). For the avoidance of doubt, the Services shall not include
the services described on Schedule 3.1(b). These Services shall be substantially
similar in nature to the services of such type previously provided by UCH in connection with
its management and operation of the Partnership Assets during the twelve (12) month period
prior to the Closing Date.

     (b) The UCH Entities shall provide the Services to the Partnership Group in a manner
that is in the good faith judgment of UCH commercially reasonable; provided,

14

 

that for so long as the UCH Entities exercise at least the same degree of care, skill and prudence in
providing the Services as customarily exercised by it for its own operation of the DCCSB,
then UCH will be deemed to have provided such Services in a commercially reasonable manner.
EXCEPT AS SET FORTH IN THE PRECEDING SENTENCE, THE UCH ENTITIES MAKE NO (AND HEREBY DISCLAIM
AND NEGATE ANY AND ALL) WARRANTIES OR REPRESENTATIONS WHATSOEVER, EXPRESS OR IMPLIED, WITH
RESPECT TO THE SERVICES. IN NO EVENT SHALL ANY UCH ENTITY OR ANY OF THEIR AFFILIATES BE
LIABLE TO ANY MEMBER OF THE PARTNERSHIP GROUP OR TO ANY OTHER PERSON FOR ANY EXEMPLARY,
PUNITIVE, INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR SPECIAL DAMAGES RESULTING FROM ANY ERROR
IN THE PERFORMANCE OF THE SERVICES, REGARDLESS OF WHETHER THE PERSON PROVIDING SUCH
SERVICES, ITS AFFILIATES, OR OTHERS MAY BE WHOLLY, CONCURRENTLY, PARTIALLY, OR SOLELY
NEGLIGENT OR OTHERWISE AT FAULT.

     (c) Any Direct Compression Equipment Costs and Expenses that are incurred by any UCH
Entity in connection with providing the Services shall be allocated to the Partnership at
the actual cost to the applicable UCH Entity providing such Services.

     (d) The General Partner shall be entitled to allocate to the Partnership any costs and
expenses (other than Direct Compression Equipment Costs and Expenses) incurred by any UCH
Entity in connection with providing the Services on any reasonable basis determined by the
General Partner. In the event that such Services are associated with UCH’s operation of
both of the businesses of the DCCSB and the Partnership Group, including, without
limitation, general and administrative functions, such reasonable basis may include, at the
election of the General Partner, allocating a portion of such costs and expenses incurred
during a particular period to the Partnership on a pro rata basis based on the Partnership
Group’s Percentage Interest.

     (e) Subject to Section 3.2, the Partnership Group hereby agrees to reimburse the UCH
Entities for all costs and expenses allocated to the Partnership Group in accordance with
the manners set forth in Sections 3.1(c) and (d).

     3.2 Limitations on Reimbursement.

     (a) Notwithstanding Section 3.1, the amount that the UCH Entities are entitled to
receive from the Partnership Group pursuant to Section 3.1 for selling, general and
administrative costs during any particular quarter during the Limit Period shall not exceed
$2.5 million (the “SG&A Limit”); provided, that with respect to the period commencing on the
Closing Date and ending on December 31, 2006, it means the product of $2.5 million
multiplied by a fraction of which the numerator is the number of days in such period and of
which the denominator is 92. The SG&A Limit shall be reduced by any selling, general and
administrative costs incurred directly by the Partnership Group during the applicable
period. In the event that during the Limit Period the Partnership Group makes any
acquisitions of assets or businesses or the business of the Partnership Group otherwise
expands after the Closing Date, then the Parties shall

15

 

negotiate in good faith any
appropriate increase in the SG&A Limit in order to account for any adjustments in the nature
and extent of the selling, general and administrative services provided by the UCH Entities
to the Partnership Group, with any such increase in the SG&A Limit subject to the approval
of the Conflicts Committee.

     (b) Notwithstanding Section 3.1, the amount that the UCH Entities are entitled to
receive from the Partnership Group pursuant to Section 3.1 for Cost of Sales during any
particular quarter during the Limit Period shall not exceed $16.95 times the Average
Horsepower of the Partnership Group during such quarter (the “Cost of Sales Limit”). The
Cost of Sales Limit shall be reduced by any Cost of Sales incurred directly by the
Partnership Group during the applicable period. In the event that during the Limit Period
the Partnership Group makes any acquisitions of assets or businesses or the business of the
Partnership Group otherwise expands after the Closing Date, then the Parties shall negotiate
in good faith any appropriate increase in the Cost of Sales Limit in order to account for
any adjustments in the Cost of Sales of the Partnership Group (on a per horsepower basis) as
a result of such acquisition or expansion, with any such increase in the Cost of Sales Limit
subject to the approval of the Conflicts Committee.

ARTICLE IV

COMPRESSION EQUIPMENT TRANSFERS

     4.1 Transfer Mechanics

     (a) In the event that UCH determines in good faith that there exists a need on the part
of the CCSB or on the part of the Partnership Group to transfer Compression Equipment
between the UCH Entities, on the one hand, and the Partnership Group, on the other hand, to
meet the compression services obligations of either of the CCSB or the Partnership Group,
such Compression Equipment shall be so transferred (or, to the extent provided in Section
4.2, leased), at the election of UCH, from a member of the UCH Entities to a member of the
Partnership Group, or from a member of the Partnership Group to a member of the UCH
Entities, as the case may be; provided, that all of the following conditions are satisfied
with respect to such transfer or lease (each such transfer or lease for the purposes of this
Article IV, unless set forth otherwise, a “transfer”) at the Effective Time (as defined
below) of such transfer:

     (i) Except as provided in Section 4.2 in respect of Compression Equipment that
is leased, such transfer will constitute a valid and absolute transfer (each such
transfer, as the case may be, constituting a “true sale” for bankruptcy law
purposes) of all right, title and interest of the Transferor in, to and under the
transferred Compression Equipment, free and clear of any Liens except for any Liens
created by the Transferee;

     (ii) Such transfer will not conflict with any of the terms and provisions of,
result in any breach of any of the terms and provisions of, or constitute (with or
without notice or lapse of time or both) a default under, the organizational
documents of the Transferor or the Transferee, or any material term of any
indenture, agreement, mortgage, deed of trust, derivative instrument or other

16

 

instrument to which the Transferor or Transferee or any of their respective
subsidiaries is a party or by which either of them is bound, or result in the
creation or imposition of any Lien upon any of their respective properties pursuant
to the terms of any such indenture, agreement, mortgage, deed of trust, derivative
instrument or other instrument, or violate any law or any order, rule, or regulation
applicable to the Transferor or Transferee or any of their respective subsidiaries
of any court or of any federal or state regulatory body, administrative agency, or
other governmental authority having jurisdiction over either of them or any of their
respective properties;

     (iii) Except as otherwise provided in this Article IV, such transfer will not
cause any member of the Partnership Group to suffer a loss of revenue under any
existing customer contract for Competitive Services or to incur any material
liabilities not reimbursed by the UCH Entities; and

     (iv) The Compression Equipment will be transferred in a condition appropriate
for the Transferee’s anticipated commercial use of such Compression Equipment;
provided, that such anticipated commercial use shall be consistent with such
equipment’s historical use; provided further, that (A) any repairs or modifications,
or any costs associated therewith, required to make such Compression Equipment
appropriate for the Transferee’s anticipated commercial use of such Compression
Equipment shall be the obligation of the Transferor and (B) the Transferee shall
have communicated its anticipated commercial use of such Compression Equipment to
the Transferor at least ten (10) Business Days prior to the anticipated date of such
transfer, failing which, the Transferor may transfer the Compression Equipment in
its then current condition.

In connection with each proposed transfer, each of the Transferee and the Transferor will
use their respective commercially reasonable efforts to cause the conditions set forth above
to be satisfied as of the Effective Time (as defined below).

     (b) All transfers of Compression Equipment pursuant to this Section 4.1 shall be deemed
to take place at 12:01 a.m. on the date of transfer (the “Effective Time”) and shall include
all of the following assets, rights and properties of the Transferor with respect to such
transferred Compression Equipment; provided, that with respect to
transfers that are effected under a lease pursuant to Section 4.2, the following
assets, rights and properties shall be so transferred to the extent provided for in, and not
inconsistent with, the relevant lease agreement, and except as provided below:

     (i) All Transferor-owned appliances, parts, instruments, machinery, accessories
and other equipment attached or installed thereto;

     (ii) The rights of the Transferor under all permits relating exclusively to
such Compression Equipment, to the extent that such permits are transferable and the
transfer of which is authorized or consented to by any third parties required to
make such transfer effective as to third parties;

17

 

     (iii) Except in the case of a lease, all warranties and guarantees, if any,
express or implied, existing for the benefit of the Transferor in connection with
such Compression Equipment to the extent assignable;

     (iv) Except in the case of a lease, any fuels, lubricants and maintenance
supplies exclusively related to such Compression Equipment;

     (v) Except in the case of a lease, all vendor information, catalogs, technical
information, specifications, designs, drawings and maintenance records related to
such Compression Equipment and to which the Transferor has ready access without
undue effort; and

     (vi) Except in the case of a lease, all rights, claims or choses in action of
the Transferor against any Person relating exclusively to such Compression
Equipment.

     (c) Except as provided in Section 4.2 in respect of Compression Equipment that is
leased, on the date of any transfer of Compression Equipment, the Transferor shall deliver
or cause to be delivered to the Transferee the following:

     (i) A general conveyance or bill of sale in the form of the Form Bill of Sale
transferring to Transferee, as of the Effective Time, good, marketable and
indefeasible title to all of the tangible personal property contemplated by Section
4.2(b) and included in the transferred Compression Equipment, free and clear of any
Liens, except for any Liens created by the Transferee;

     (ii) All appropriate documents for the assignment as of the Effective Time of
the Transferor’s rights under the permits referred to in Section 4.1(b)(ii),
together with all consents of third parties required to make such assignments
effective as to such third parties; and

     (iii) Such other instruments of transfer and assignment in respect of the
transferred Compression Equipment as the Transferee shall reasonably require and as
shall be consistent with the terms and provisions of this Agreement.

     4.2 Settlement; Appraised Value

     (a) Prior to the Effective Time of any transfer pursuant to Section 4.1, the
Partnership Group and UCH will determine the aggregate Appraised Value of the Compression
Equipment to be so transferred.

     (b) In consideration for such transfer, the Transferee, at its discretion (subject to
the provisos of Sections 4.2(b)(ii) and (ii) and subject to Sections 4.2(b) and (c)), shall
take any one or more of the following actions prior to or contemporaneously with the
Effective Time of such transfer:

     (i) Transfer Compression Equipment to the Transferor of equal or greater
Appraised Value than the Appraised Value of the Compression Equipment

18

 

to be transferred to the Transferee pursuant to Section 4.1 (provided, that if such
Compression Equipment is of greater Appraised Value than the Appraised Value of the
Compression Equipment to be transferred to the Transferee pursuant to Section 4.1,
such excess Appraised Value shall be deemed to be a transfer of Compression
Equipment with a value equal to such excess Appraised Value and Transferor shall be
required to take one or more of the actions contemplated by this Section 4.2(b) in
consideration for such excess Appraised Value) in accordance with this Article IV;

     (ii) Execute and deliver a lease agreement substantially in the form of the
Form Lease Agreement pursuant to which the Transferee agrees to lease from the
Transferor the Compression Equipment to be transferred to the Transferee pursuant to
Section 4.1, which lease agreement shall be counter-signed by the Transferor
(provided, however, that the ability of the Transferee to execute and deliver such a
lease may be limited in the sole discretion of UCH, to the extent that a UCH Entity
is the Transferor, or in the sole discretion of the Conflicts Committee, to the
extent that a member of the Partnership Group is the Transferor); or

     (iii) Deliver to the Transferor cash (or an obligation to make payment in cash
no later than the end of the fiscal quarter in which the transfer is effected) in
the amount of the aggregate Appraised Value of the Compression Equipment to be
transferred to the Transferee pursuant to Section 4.1 (provided, however, that the
ability of the Transferee to make such a payment may be limited in the sole
discretion of UCH, to the extent that a UCH Entity is the Transferor, or in the sole
discretion of the Conflicts Committee, to the extent that a member of the
Partnership Group is the Transferor).

     (c) In the event that the Transferee cannot through the use of its commercially
reasonable efforts provide adequate consideration to the Transferor for Compression
Equipment to be transferred in any of the manners set forth in Section 4.2(b), then no such
transfer pursuant to the terms of this Article IV shall occur.

     (d) Notwithstanding Section 4.2(b), if the Transferor is a member of the Partnership
Group, the Transferee shall not be entitled to take the actions contemplated by Section
4.2(b)(ii) if such action would cause the Partnership to be treated as an association
taxable as a corporation or otherwise to be taxed as an entity for federal income tax
purposes. In such event, if compliance by UCH with Sections 4.2(i) or (iii) is not
commercially practicable, the Partnership and UCH shall negotiate in good faith to reach
agreement on another manner in which to reimburse the Partnership for such Compression
Equipment; provided, that the final terms of such reimbursement shall be approved by the
Conflicts Committee.

19

 

     4.3 Appraisal. UCH shall, at its sole cost and expense, cause an Appraisal of all Compression
Equipment then owned by the CCSB and the Partnership Group to be conducted and prepared (i) no
later than the end of the fiscal quarter in which the second anniversary of the Closing Date occurs
and (ii) no less frequently than every two years thereafter.

     4.4 Like-Kind Exchange Treatment. Each Party agrees to cooperate to the extent reasonably
necessary to allow the other, if the other so desires, to treat the transactions contemplated by
Section 4.1(b) as a like-kind exchange under Section 1031 of the Code, and relevant Treasury
regulations and/or under relevant state law provisions, if any. Any Party seeking such treatment
acknowledges that it has consulted or will consult with independent tax counsel regarding the
applicability and benefits/detriments of such treatment and in no way has relied upon any
representations of the other party regarding the same.

     4.5 Other Sales Permitted. Nothing otherwise set forth in this Article IV shall be deemed to
preclude any of the UCH Entities and any member of the Partnership Group from negotiating or
consummating at any time the purchase and sale of newly fabricated Compression Equipment, existing
Compression Equipment or all or any part of the DCCSB; provided, however, that such negotiations or
purchase and sale shall be conducted pursuant to the terms and procedures then mutually agreed upon
by UCH and the General Partner or the Conflicts Committee, as applicable.

     4.6 Termination. Unless this Agreement has otherwise terminated pursuant to Section 8.4, this
Article IV shall terminate on the first to occur of the following: (i) the third anniversary of
the Closing Date and (iii) a Change of Control of UCH.

     4.7 Proration of Ad Valorem Taxes. Ad valorem taxes relating to the ownership of Compression
Equipment transferred pursuant to Section 4.1 shall be prorated on a daily basis between the UCH
Entities and the Partnership Group with the UCH Entities and the Partnership Group responsible for
the prorated
portion of such taxes for the period of their respective ownership of such transferred
Compression Equipment. As between the UCH Entities and the Partnership Group, the party that
receives the ad valorem tax billing (the “Billed Party”) shall provide a copy of such billing to
the other party together with a calculation of the prorated ad valorem taxes owed by each party.
The party that did not receive the ad valorem tax billing shall pay its prorated portion of the ad
valorem taxes to the Billed Party prior to the due date of such taxes and the Billed Party shall be
responsible for the timely payment of the ad valorem taxes to the taxing authorities.

ARTICLE V

NEWLY FABRICATED COMPRESSION EQUIPMENT PURCHASES

     The Parties hereby acknowledge that none of the UCH Entities is under any obligation to offer
or sell to any member of the Partnership Group newly fabricated Compression Equipment and no member
of the Partnership Group is under any obligation to purchase from any of the UCH Entities newly
fabricated Compression Equipment; provided, that in the event that the General Partner and UCH
mutually agree to enter into, or cause their respective Affiliates to

20

 

enter into, a purchase and
sale agreement for the purchase and sale of newly fabricated Compression Equipment, (i) such
purchase and sale shall be subject to the standard terms and conditions then utilized by the UCH
Entities for purchases and sales of newly fabricated Compression Equipment and (ii) any member of
the Partnership Group shall be permitted to purchase such Compression Equipment for a price that is
not more than the Fabricated Cost of such Compression Equipment plus the Fixed Margin Amount.

ARTICLE VII

INDEMNIFICATION

     7.1 Environmental Indemnification.

     (a) Subject to Section 7.3, UCH shall indemnify, defend and hold harmless the
Partnership Group from and against any environmental claims, losses and expenses (including,
without limitation, court costs and reasonable attorney’s and expert’s fees) of

22

 

any and
every kind or character, known or unknown, fixed or contingent, suffered or incurred by the
Partnership Group by reason of or arising out of:

     (i) any violation of Environmental Laws associated with the ownership or
operation of the Partnership Assets; or

     (ii) any event or condition associated with ownership or operation of the
Partnership Assets (including, without limitation, the presence of Hazardous
Substances on, under, about or migrating to or from the Partnership Assets or the
disposal or release of Hazardous Substances generated by operation of the
Partnership Assets) including, without limitation, (A) the cost and expense of any
investigation, assessment, evaluation, monitoring, containment, cleanup, repair,
restoration, remediation, or other corrective action required or necessary under
Environmental Laws or to satisfy any applicable Voluntary Cleanup Program, (B) the
cost or expense of the preparation and implementation of any closure, remedial,
corrective action or other plans required or necessary under Environmental Laws or
to satisfy any applicable Voluntary Cleanup Program and (C) the cost and expense for any environmental pre-trial, trial, or appellate
legal or litigation support work; provided, in the case of clauses (A) and (B) such
cost and expense shall not included the costs of and associated with project
management and soil and ground water monitoring;

but only to the extent that such violation complained of under Section 7.1(a)(i) or such
events or conditions included under Section 7.1(a)(ii) occurred before the Closing Date
(collectively, “Covered Environmental Losses”).

     (b) The Partnership Group shall indemnify, defend and hold harmless UCH and its
Affiliates from and against any Covered Environmental Losses suffered or incurred by UCH and
its Affiliates relating to the Partnership Assets occurring on or after the Closing Date,
except to the extent that the Partnership Group is indemnified with respect to any of such
Covered Environmental Losses under Section 7.1(a), and unless such indemnification would not
be permitted under the Partnership Agreement by reason of one of the provisos contained in
Section 7.7(a) of the Partnership Agreement.

     (c) Except for claims for Covered Environmental Losses made before the third
anniversary of the Closing Date, which shall not terminate, all indemnification obligations
in this Section 7.1 shall terminate on the third anniversary of the Closing Date.

     7.2 Additional Indemnification.

     (a) In addition to and not in limitation of the indemnification provided under Section
7.1(a), subject to Section 7.3 and except as otherwise set forth in any Exhibit hereto, UCH
shall indemnify, defend and hold harmless the Partnership Group from and against any claims,
losses and expenses (including, without limitation, court costs and reasonable attorney’s
and expert’s fees) of any and every kind or character, known or

23

 

unknown, fixed or
contingent, suffered or incurred by the Partnership Group (“Other Losses”) by reason of or
arising out of:

     (i) failure to convey good and defensible title to the Partnership Assets to
one or more members of the Partnership Group, and such failure render the
Partnership Group unable to use or operate the Partnership Assets in substantially
the same manner as they were operated by the UCH Entities immediately prior to the
Closing Date;

     (ii) events and conditions associated with the Retained Assets whether
occurring before or after the Closing Date; and

     (iii) all federal, state and local income tax liabilities attributable to the
operation of the Partnership Assets prior to the Closing Date, including any such
income tax liabilities of UCH that may result from the consummation of the formation
transactions for the Partnership Entities;

provided, however, that in the case of clauses (i) and (ii) above, such indemnification
obligations shall terminate on the third anniversary of the Closing Date; and that in the
case of clause (iii) above, such indemnification obligations shall survive until sixty (60)
days after the termination of any applicable statute of limitations.

     (b) In addition to and not in limitation of the indemnification provided under Section
7.1(b) and the Partnership Agreement and except as otherwise set forth in any Exhibit
hereto, the Partnership Group shall indemnify, defend and hold harmless UCH and its
Affiliates from and against any claims, losses and expenses (including, without limitation,
court costs and reasonable attorney’s and expert’s fees) of any and every kind or character,
known or unknown, fixed or contingent, suffered or incurred by UCH and its Affiliates by
reason of or arising out of events and conditions associated with the operation of the
Partnership Assets and occurring on or after the Closing Date unless such indemnification
would not be permitted under the Partnership Agreement by reason of one of the provisos
contained in Section 7.7(a) of the Partnership Agreement.

7.3 Limitations Regarding Indemnification. The aggregate liability of UCH under
Section 7.1(a) shall not exceed $5.0 million.

     (b) No claims may be made against UCH for indemnification pursuant to Sections 7.1(a)
or 7.2(a) unless the aggregate dollar amount of the Losses suffered or incurred by the
Partnership Group or the Partnership Indemnitees exceed $250,000, after such time UCH shall
be liable for the full amount of such claims, subject to the limitations of Section 7.3(a).

     (c) Notwithstanding anything herein to the contrary, in no event shall UCH have any
indemnification obligations under Section 7.1(a) for claims made as a result of additions to
or modifications of Environmental Laws promulgated after the Closing Date.

     7.4 Indemnification Procedures

24

 

     (a) The Indemnified Party agrees that promptly after it becomes aware of facts giving
rise to a claim for indemnification under this Article VII, it will provide notice thereof
in writing to the Indemnifying Party, specifying the nature of and specific basis for such
claim; provided, however, that the Indemnified Party shall not submit claims more frequently
than once a calendar quarter (or twice in the case of the last calendar quarter prior to the
expiration of the applicable indemnity coverage under this Agreement).

     (b) The Indemnifying Party shall have the right to control all aspects of the defense
of (and any counterclaims with respect to) any claims brought against the Indemnified Party
that are covered by the indemnification under this Article VII, including, without
limitation, the selection of counsel, determination of whether to appeal any decision of any
court and the settling of any such matter or any issues relating thereto; provided, however,
that no such settlement shall be entered into without the consent of the Indemnified Party
(with the concurrence of the Conflicts Committee in the case of the Partnership Group)
unless it includes a full release of the Indemnified Party
from such matter or issues, as the case may be, and does not include the admission of
fault, culpability or a failure to act, by or on behalf of such Indemnified Party.

     (c) The Indemnified Party agrees to cooperate fully with the Indemnifying Party, with
respect to all aspects of the defense of any claims covered by the indemnification under
this Article VII, including, without limitation, the prompt furnishing to the Indemnifying
Party of any correspondence or other notice relating thereto that the Indemnified Party may
receive, permitting the name of the Indemnified Party to be utilized in connection with such
defense, the making available to the Indemnifying Party of any files, records or other
information of the Indemnified Party that the Indemnifying Party considers relevant to such
defense and the making available to the Indemnifying Party, at no cost to the Indemnifying
Party, of any employees of the Indemnified Party; provided, however, that in connection
therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact
thereof on the operations of the Indemnified Party and further agrees to endeavor to
maintain the confidentiality of all files, records and other information furnished by the
Indemnified Party pursuant to this Section 7.4. In no event shall the obligation of the
Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately
preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire
and pay for counsel in connection with the defense of any claims covered by the
indemnification set forth in this Article VII; provided, however, that the Indemnified Party
may, at its own option, cost and expense, hire and pay for counsel in connection with any
such defense. The Indemnifying Party agrees to keep any such counsel hired by the
Indemnified Party informed as to the status of any such defense, but the Indemnifying Party
shall have the right to retain sole control over such defense.

     (d) In determining the amount of any loss, cost, damage or expense for which the
Indemnified Party is entitled to indemnification under this Agreement, the gross amount of
the indemnification will be reduced by (i) any insurance proceeds realized by the
Indemnified Party and (ii) all amounts recovered by the Indemnified Party under contractual
indemnities from third Persons. The Partnership hereby agrees to use

25

 

commercially
reasonable efforts to realize any applicable insurance proceeds or amounts recoverable under
such contractual indemnities.

     (e) The date on which the Indemnifying Party receives notification of a claim for
indemnification shall determine whether such claim is timely made.

Exhibit B

GAS COMPRESSOR EQUIPMENT MASTER RENTAL AGREEMENT

     This Gas Compressor Equipment Master Rental Agreement with all Schedule(s),
hereinafter referred to as the (“Agreement”), is made between
                 
(“Lessor”) and
                 
(“Lessee”).

Lessor and Lessee Agree as follows:

1. Lease. Subject to and on the terms and conditions herein set forth in Article IV of the Omnibus
Agreement among Universal Compression Holdings, Inc., Universal Compression, Inc., UCO GP, LLC, UCO
General Partner, LP, Universal Compression Partners, L.P., UCLP OLP GP LLC and UC Operating
Partnership (the “Omnibus Agreement”) and herein, Lessor hereby agrees to lease to Lessee, and
Lessee hereby agrees to lease from Lessor, the personal property described as the “Equipment” on
the respective Equipment Lease schedule(s) executed by Lessee and Lessor from time to time
hereunder upon agreement of Lessor and Lessee. Each Schedule shall, upon execution, be deemed to
incorporate all of the provisions of this Agreement except as otherwise set forth therein.

2. Term and Rent. Except as otherwise provided herein, this Agreement shall terminate on the later
to occur of (i) termination of the Omnibus Agreement and (ii) termination of the last existing
Schedule issued hereunder. Each Schedule shall set forth the term of the lease (“Minimum Term”)
and the number and amount of rental payments for the Equipment listed thereon, which Lessee shall
pay as set forth. If Lessee fails to pay any rental or other sum when due, Lessee also shall pay
to Lessor interest thereon from the due date thereof to the date of payment at a rate equal to the
lesser of 18% per annum or the maximum rate permitted by applicable law (“Applicable Rate”). All
payments by Lessee hereunder shall be payable at the office of Lessor set forth below, or at such
other place as Lessor from time to time may designate in writing. It is the intent of the parties
that each Schedule shall have a Minimum Term that is no greater than a whole or fractional month
less than 75% of the useful life of the Equipment subject to said Schedule. Notwithstanding
anything in this Agreement to the contrary, a Schedule may be terminated prior to the expiration of
its Minimum Term upon the purchase and sale or exchange between Lessor and Lessee of the Equipment
subject to said Schedule in accordance with the term of the Omnibus Agreement.

3. Taxes. Lessee agrees to reimburse, promptly when due, all license fees and assessments and all
sales, use, property, excise and other taxes or charges (including any interest and penalties), now
or hereafter imposed by any governmental body or agency upon the Equipment or the purchase,
ownership, possession, leasing, operation, use, or disposition thereof hereunder, or the rentals or
other payments hereunder (excluding taxes on or measured by the net income of Lessor) and prepare
and file promptly with the appropriate offices any and all tax and other similar returns required
to be filed with respect thereto (sending copies thereof to Lessor) or, if requested by Lessor,
notify Lessor of such requirement and furnish Lessor with all information required by Lessor so
that it may effect such filing.

4. Inspection and Acceptance. Within 48 hours after delivery of the Equipment to be leased to
Lessee under each Schedule, Lessee shall inspect the Equipment. Unless within said 48 hour period
Lessee notifies Lessor in writing to the contrary stating the details of any defects, Lessee shall
be conclusively presumed to have accepted the Equipment in its then condition. If within said 48
hour period Lessee notifies Lessor in writing of the unacceptability of the Equipment, Lessor’s
obligations to lease the Equipment shall cease forthwith. Upon acceptance of delivery, Lessee
assumes the care, custody, supervision and control of the Equipment and of any and all persons or
property in the vicinity of the Equipment during the time of delivery, operation and return.
Lessee acknowledges that all Equipment rented hereunder and specified in the Schedule(s) is of the
size, design and capacity selected for the operating conditions furnished to Lessor by Lessee and
is suitable for Lessee’s purposes. Lessee acknowledges that that Lessor is not the manufacturer or
supplier of the Equipment and any quotations or recommendations made by Lessor are based on
information supplied by Lessee and the manufacturer or supplier of the Equipment.

5. Freight. Lessee agrees to bear all of the cost of connecting the Equipment and of disconnecting
the Equipment prior to returning the Equipment to Lessor. Except as otherwise provided in the
Schedule, all costs of transporting the Equipment from Lessor’s yard to Lessee’s Site described on
the Schedule and of transporting the Equipment from such Site back to Lessor’s yard will be at the
expense of Lessee.
Houston 3001865v.3

6. Insurance. Lessee shall, at Lessee’s sole cost and expense, maintain insurance or
Lessor-approved self-insurance in such amounts, against such risks (including, without limitation,
all risk and public liability insurance with respect to the Equipment), with such carriers and in
such form as shall be satisfactory to Lessor naming Lessee as an insured and Lessor as an
additional insured. Lessee shall provide Lessor with evidence of such insurance. The policies for
such insurance shall provide that Lessor receive thirty (30) days notice of any termination,
cancellation or alteration of the terms of such insurance, shall provide that the coverage afforded
to Lessor shall not be rescinded, impaired or invalidated by any act or neglect of lessee and shall
provide for waiver of subrogation and contribution by Lessee and Lessee’s insured against Lessor
and Lessor’s employees and agents.

GAS COMPRESSOR EQUIPMENT MASTER RENTAL AGREEMENT

7. Use / Lessee’s Responsibilities. Lessee agrees to use the Equipment in a careful and prudent
manner with competent agents, employees or subcontractors only for the compression of gas in
accordance with the specifications of the manufacturer of the Equipment. Lessee agrees to pay for
damages to the Equipment resulting from free water, excessive condensate or foreign solids, or
impurities contained in the gas stream. Lessee further agrees to pay for all damages to the
Equipment resulting from abusive use, failure to maintain the Equipment in accordance with this
agreement or from any negligence on the part of Lessee, its agents, employees or subcontractors.

     In addition to any Lessee obligations contained elsewhere in this Agreement and within any
Schedules hereto, Lessee agrees to and shall:

     a. Provide Lessor with authorized ingress and egress to and from the site designated in the
Schedule for installation of the Equipment (the “Site”). Should Lessor be denied access to the
Site for any reason not reasonably within Lessor’s control, any time lost by Lessor shall be paid
for by Lessee at the applicable rate. Recognizing that Lessee has superior knowledge of the Site
and access routes to the Site, Lessee must advise Lessor of any conditions or obstructions which
Lessor might encounter while en route to the Site. Lessee agrees to maintain the road and Site in
such a condition that will allow free access and movement to and from the Site in an ordinarily
equipped highway type vehicle. If because of an attribute of Lessee’s operations, Lessor is
required to use any specialized transportation equipment, cranes or other services and supplies,
Lessee shall furnish the same at its expense and without cost to Lessor;

     b. Prepare a sound location at the Site adequate in size and capable of properly supporting
the Equipment; and

     c. Immediately mitigate and repair any stoppage, malfunction or leaks of oil or coolant from
the Equipment.

8. No Maintenance / Bare Rental. Lessee acknowledges that Lessor is providing the Equipment as a
“bare rental” and, therefore, Lessor will have no maintenance or inspection obligations with
respect to the Equipment.

9. Inspection. Lessor shall have the right at all reasonable times to enter upon the premises
where the Equipment may be located for the purpose of inspecting it or observing its use.

10. Title; Personal Property; Encumbrances; Location. Lessee covenants that:

     a. The Equipment is and shall remain personal property and shall not be attached to or become
part of any realty;

     b. The Equipment will be installed and used at the location specified in the Schedule
pertaining thereto and that it shall not be removed therefrom without the permission of Lessor;

     c. That Lessee will not, except as expressly authorized in this Agreement, sell, secrete,
mortgage, assign, transfer, lease, sublet, loan part with possession of, or encumber the Equipment
or permit any liens or charges to become effective thereon or permit or attempt to do any of the
acts aforesaid. Lessee agrees, at Lessee’s own expense, to take such action as may be necessary to
remove any such encumbrance, lien or charge and to prevent any third party from acquiring any other
interest in the Equipment (including, without limitation, by reason of such Equipment being deemed
to be a fixture or a part of any realty); and

     d. Lessee will not change or remove any insignia, serial number or lettering of the Equipment.

11. Licenses, Permits and Compliance. Lessee, at its sole expense, shall;

     a. Comply with all applicable rules and regulations of any Federal, Provincial, State, County,
City, local, municipal or regulatory agency (hereinafter referred to as “Governing Bodies”)
relating to the construction or operation of the Equipment in the Location, or environmental
requirements associated therewith (including but not limited to air emission, noise and
environmental discharges); and

     b. Obtain and maintain throughout the Minimum Term, or any extension thereof, any and all
licenses and/or permit fees assessed as a result of this Agreement or against said Equipment.
Lessee further agrees to defend, protect, indemnify and hold harmless Lessor from any and all
liability associated with its failure to comply with the foregoing provision.

12. Waste Disposal. Lessee bears responsibility for disposal of liquids, solid, and hazardous waste
discharged by the Equipment at the location in accordance with federal, state and local
environmental rules and regulations.

13. Events of Default; Remedies; Expenses. In the event that:

     a. Lessee shall default in the payment of any installment of rent or other sum payable under
this Agreement or default in the observance or performance of any other covenant or agreement in
this Agreement and the failure to cure said default within ten (10) days after notice by Lessor; or

     b. Lessee shall dissolve, or become insolvent (however evidenced) or bankrupt, commit any
act of bankruptcy, make an assignment for the benefit of creditors, suspend the transaction of its
usual business or consent to the appointment of a trustee or receiver, or a trustee or a receiver
shall be appointed for Lessee or for a

Page 2 of 9

 

Exhibit B

GAS COMPRESSOR EQUIPMENT MASTER RENTAL AGREEMENT

substantial part of its property, or bankruptcy, reorganization, insolvency, or similar
proceedings shall be instituted by or against Lessee; or

     c. an order, judgment, or decree shall be entered against Lessee by a court of competent
jurisdiction and such order, judgment or decree shall continue unpaid or unsatisfied and in effect
for any period of sixty (60) consecutive days without a stay of execution, or any execution or writ
or process shall be issues in connection with any action or proceeding against Lessee or its
property whereby the Equipment or any substantial part of Lessee’s property may be taken or
restrained; or

     d. any indebtedness of Lessee for borrowed money shall become due and payable by acceleration
of maturity thereof;

     e. Lessor shall in good faith believe that the prospect of payment or performance by Lessee is
impaired, then and in any such event, Lessor may, by written notice to Lessee:

     (1) Immediately terminate this Agreement as to any or all Schedules, at its option, and
Lessee’s rights thereunder; and/or

     (2) Declare immediately due, and payable all rental installments and other sums hereunder
forthwith due and payable whereupon the same shall forthwith become due and payable as liquidated
damages and not as a penalty; and/or

     (3) Proceed by appropriate court action or actions either at law or in equity, to enforce
performance by Lessee of the applicable covenants of this Agreement or to recover damages for the
breach thereof; and/or

     (4) Without necessity of process or other legal action, enter onto the premises of Lessee or
such other premises as the Equipment may then be located and stop the operation of the Equipment
and/or take possession of the Equipment, disconnecting and separating the Equipment from any other
property and using all force necessary or permitted by applicable law, without Lessor incurring any
liability to Lessee or any other person arising out of the taking of any such action. Lessee
agrees to and shall indemnify and hold harmless Lessor from any and all claims, losses, damages,
causes of action, suits and liabilities of any kind arising in favor of Lessee, or any interest
owner that Lessee represents or serves as operator and arising out of or in connection with the
stopping of the operation of the Equipment and/or the removal of the Equipment as aforesaid,
whether same result from the forfeiture of any oil, gas or mineral lease, damage to a producing
reservoir or lease operations, lost production or other event or condition. In addition, Lessee
shall continue to be liable for all other indemnities under this Agreement and for all legal fees
and other costs and expenses resulting from the foregoing defaults or the exercise of Lessor’s
remedies. Lessor shall be entitled to take or retain, by way of offset against any or all amounts
due and owing under this Agreement, any assets, tangible or intangible, of Lessee which may then be
in the possession of Lessor, its correspondents or agents, wheresoever situated.

14. Holding Over. Unless a party gives the other party thirty (30) days advance written notice of
termination prior to the expiration of the Minimum Term specified in a Schedule, that Schedule will
continue to bind the parties on a month-to-month basis as to the Equipment, subject thereafter to
termination by either party with thirty (30) days advance written notice.. Notwithstanding the
foregoing, after the expiration of the Minimum Term, Lessor may modify the rental fees and other
charges assessed under this Agreement.

15. Indemnity of Lessor.

     a. Lessee is responsible and liable for loss of or damage to Equipment arising between the
time of delivery and redelivery of the Equipment and Lessee shall protect, defend, indemnify and
hold Lessor harmless from and against any such loss or damage, however arising, including but not
limited to, improper operation, improper maintenance (unless Lessor performs maintenance),
negligent acts of Lessee, compression of dirty or wet gas, fire, freezing, theft, windstorm,
hailstorm, flood, riot, insurrection or explosion, except to the extent such loss or damage arises
directly as a result of the negligence of Lessor.

     b. Lessee shall protect, defend, indemnify and hold Lessor harmless from and against any loss,
damage, liability, suit, expense, cost or claim, however occurring as the result of loss of or
damage to property (other than the Equipment), arising between the time of delivery and redelivery
of the Equipment, whether such property is owned by Lessee or third party, and for injury to or
death of persons, whether Lessee or its employees or third parties.

16. Savings Clause. The parties agree that the indemnities in this Agreement are limited to the
extent necessary to comply with applicable state or federal law and that this Agreement shall be
deemed to be amended to comply with those laws to the extent their requirements are at variance
with any indemnification provisions set forth in this Agreement.

17. Limitation of Liability. In no event shall Lessor, its agents and employees (for purposes of
this Paragraph 17, such persons shall collectively be referred to as “Lessor”) be liable to Lessee,
for any general, compensatory, special indirect, incidental or consequential damages related to or
in connection with the use and

Page 3 of 9

 

Exhibit B

GAS COMPRESSOR EQUIPMENT MASTER RENTAL AGREEMENT

operation of the Equipment and/or the performance of this Agreement, including but not limited to
any injury, loss or damage to any property, any loss of profits or business opportunity, and any
loss of use of the Equipment, irrespective of the reason or cause of such damages, whether any of
such damages occur during or after the period of this Agreement, or that the claim for such damages
is based on warranty, contract, tort or other theory of any nature whatsoever.

18. Assignment By Lessor. Lessor may assign its rights and delegate its duties under this
Agreement. Lessor covenants to Lessee that Lessor is empowered to execute this Agreement.
Conditioned upon Lessee’s performing the conditions hereof, Lessee shall peaceably and quietly
hold, possess and use the Equipment during the Minimum Term and any extensions thereof without
hindrance. If Lessor assigns the rents reserved herein or all or any of Lessor’s rights hereunder,
such assignee’s rights shall be independent of any claim of Lessee against Lessor. Lessee on
receiving notice of any such assignment shall abide thereby and make payment as may therein be
directed. Following such assignment, the term “Lessor’ shall be deemed to include or refer to
Lessor’s assignee, except such assignee’s rights shall be independent of any claim of Lessee
against Lessor as hereinabove provided.

19. Assignment and Subleasing by Lessee. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS PARAGRAPH
19, LESSEE SHALL NOT, WITHOUT THE PRIOR CONSENT OF LESSOR, ASSIGN, TRANSFER OR ENCUMBER ITS RIGHTS,
INTERESTS OR OBLIGATIONS UNDER THIS AGREEMENT. ANY ATTEMPTED ASSIGNMENT, TRANSFER OR ENCUMBRANCE
BY LESSEE OF ITS RIGHTS, INTERESTS OR OBLIGATIONS UNDER THIS AGREEMENT SHALL BE NULL AND VOID. So
long as no material event of default shall have occurred and be continuing, Lessee may, without the
consent of Lessor, sublease one or more of the Equipment to any third party (each third part a
“User” and each such lease a “User Lease”), provided that all of the following requirements shall
be satisfied with respect to each such User Lease entered into pursuant to this Paragraph 19:

     a. the Equipment is and will remain physically located within the United States;

     b. such User Lease shall be in writing, shall identify the Equipment by unit number, engine,
frame and number of cylinders and shall expressly prohibit any further sublease or transfer by User
of any rights or interests in the Equipment without Lessee’s permission;

     c. such User Lease shall prohibit the User from making any alterations or modifications to the
Compressors that would violate the provisions of Paragraph 23 of this Agreement; and

     d. such User Lease shall require the User (and/or Lessee) (i) to maintain the Equipment in
accordance with Paragraph 7 and the relevant Schedule and (ii) to engage in activities with the
Equipment in a manner consistent with the Equipment’s intended purpose and in accordance with the
Equipment’s specifications.

     No such subleasing by Lessee will reduce or affect any of the obligations of Lessee hereunder
or the rights of Lessor under this Agreement, and all of the obligations of Lessee hereunder shall
be and remain primary and shall continue in full force and effect as the obligations of a principal
and not of a guarantor or surety.

20. No Lessor Equipment Warranties. LESSOR LEASES THE EQUIPMENT TO LESSEE AS-IS AND EXPRESSLY
DISCLAIMS AND MAKES NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE CONDITION, DESIGN, QUALITY,
CAPACITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF, OR ANY OTHER MATTER, CONCERNING
THE EQUIPMENT. LESSEE HEREBY WAIVES ANY CLAIM (INCLUDING ANY CLAIM BASED ON STRICT OR ABSOLUTE
LIABILITY IN TORT) IT MAY HAVE AGAINST LESSOR FOR ANY LOSS, DAMAGE (INCLUDING INCIDENTAL OR
CONSEQUENTIAL DAMAGE) OR EXPENSES CAUSED BY OR RELATING TO THE EQUIPMENT.

21. Enforceability. If any part hereof is contrary to, prohibited by or deemed invalid under
applicable laws or regulations of any jurisdiction, such provision shall be inapplicable and deemed
omitted but shall not invalidate the remaining provisions hereof.

22. No Conditional Sale. It is the intention of the parties hereto to hereby create a lease on the
Equipment described herein, and not a conditional sale. To provide solely for the eventuality that
a court might hold this to be a conditional sale, Lessor hereby retains a purchase money security
interest to secure payment of the sales price of the Equipment as determined by such court, and
Lessee grants to Lessor all rights given to a secured party under the Uniform Commercial Code in
addition to Lessor’s other rights hereunder. It is the intention of the parties that the Equipment
shall be deemed personal property and that it not be deemed a fixture, even though it may be
attached in some manner to realty. To provide solely for the eventuality that a court might also
hold the Equipment to be a fixture, the parties state for the purpose of complying with the legal
requirements for a financing statement that collateral is or includes fixtures and the Equipment is
affixed or is to be affixed to the lands described in the Schedule(s).

23. Alterations.

     a. Except as required or permitted by this Agreement, and subject to this Paragraph 23, Lessee
shall not modify or alter the Equipment without the prior approval of Lessor.

Page 4 of 9

 

Exhibit B

GAS COMPRESSOR EQUIPMENT MASTER RENTAL AGREEMENT

     b. Lessee may make any optional renovation, improvement, addition, or alteration to the
Equipment (“Optional Alteration”) provided that such Optional Alteration does not impair the value,
use or remaining useful life of such Equipment. In the event an Optional Alteration is readily
removable without impairing the value, use or remaining useful life of the Equipment, and is not a
part or appliance which replaces any part or appliance originally incorporated or installed in or
attached to such Equipment on the effective date of the relevant Schedule, Lessee may (or, if
requested by Lessor shall) remove such Optional Alteration whereupon such Optional Alteration will
remain the property of Lessee. To the extent such Optional Alteration is not readily removable
without impairing the value, use or remaining useful life of the Equipment to which such Optional
Alteration has been made, or is a part or appliance which replaces any part or appliance originally
incorporated or installed in or attached to such Equipment on the effective date of the relevant
Schedule, such Optional Alteration shall, without further act, immediately be and become the
property of, and title shall vest in, Lessor, free and clear of all liens and shall be subject to
the terms of this Agreement. Any parts installed or replacements made by Lessee upon the Equipment
pursuant to its obligation to maintain and keep the Equipments in the condition required pursuant
to the terms of this Agreement shall be considered accessions to such Equipment and ownership
thereof shall be immediately vested in Lessor.

24. Miscellaneous.

     a. No covenant or condition of this Agreement can be waived or changed except by the written
consent of both parties. Forbearance or indulgence by Lessor in any regard whatsoever shall not
constitute a waiver or change of the covenant or condition to be performed by Lessee to which the
same may apply, and until complete performance by Lessee of said covenant or condition, Lessor
shall be entitled to invoke any remedy available to Lessor under this Agreement or by law or equity
despite said forbearance or indulgence. Waiver of any defaults shall not waive any other default.

     b. Service of all notices under this Agreement shall be sufficient if mailed to the party
involved at its respective address set forth below, or at such address as such party may provide in
writing. Any such notices mailed to such address shall be effective when deposited in the United
States mail, duly addressed and with postage prepaid.

     c. “Lessor” and “Lessee” as used in this Agreement shall include the heirs, executors,
administrators, successors, sub-lessees and/or assigns of such parties.

     d. If more than one Lessee executes this Agreement, their obligations under this Agreement
shall be joint and several.

     e. Lessee will, if requested by Lessor, join with Lessor in executing one or more financing
statements, as may be desired by Lessor, in form satisfactory to Lessor.

     f. In case of conflict between provisions found in this Agreement and those listed in the
Schedule(s) hereto, the provisions on the Schedule(s) shall prevail.

     g. The law governing this Agreement shall be that of the State of Texas in force at the date
of this Agreement, excepting any conflict of laws provisions that provide for the application of
the laws of another jurisdiction.

     h. Lessor and Lessee agree that venue of any lawsuit arising from or in connection with the
terms of this Agreement shall be in Houston, Harris County, Texas.

     i. This Agreement contains the full agreement between the parties. No representation or
promise has been made by either party to the other as an inducement to enter into this Agreement.
Lessor does not in any way or for any purpose become partner of Lessee, or a joint venture, or a
member of a joint enterprise with Lessee.

     j. Lessee hereby waives its right to receive a copy of any financing statement or financing
change statement registered by Lessor in connection with this Agreement.

     k. Lessor and Lessee hereby agree that no rights or remedies referred to in Article
2A of the Uniform Commercial Code shall be conferred upon either Lessor or Lessee unless expressly
granted in this Agreement..

     l. If Lessee at any time shall fail to pay any sum which Lessee is required by this Agreement
to pay or shall fail to do or perform any other act Lessee is required by this Agreement to do or
perform, Lessor at its option may pay such sum or do or perform such act (or have it performed by a
third party), and Lessee shall reimburse Lessor on demand for the amount of such payment and for
the cost and expenses which may be incurred by Lessor for such acts or performance, together with
interest thereon at the Applicable Rate from the date of demand until paid.

     m. This Agreement is based on the applicable laws existing at the time of its execution. Any
changes, including changes in governmental enforcement practices, revisions or new applicable laws,
including without limitation those related to taxes, permits, fees and duties, that have the effect
of increasing Lessor’s burden, including but not limited to cost, time-consumption and risk
exposure, shall entitle Lessor to fair and equitable Agreement modifications, which modifications
the parties agree to work toward in good faith and in a timely

Section 2.06(c), as of the effective date of such increase, payable to the order of such Lender in
a principal amount equal to its Revolving Commitment or Term Commitment as in effect on such date,
and otherwise duly completed. In the event that any Lender’s Revolving Commitment or Term
Commitment increases or decreases for any reason (whether pursuant to Section 2.06, Section
12.04(c) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date
of such increase or decrease, a new Note payable to the order of such Lender in a principal amount
equal to its Revolving Commitment or Term Commitment after giving effect to such increase or
decrease, and otherwise duly completed. The date, amount, Type, interest rate and, if applicable,
Interest Period of each Loan made by each Lender and all payments made on account of the principal
thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer,
may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or
on any separate record maintained by such Lender. Failure to make any such notation or to attach a
schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such
Loans or affect the validity of such transfer by any Lender of its Note.

     Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by
telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 p.m., Eastern time, three
(3) Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing,
not later than 12:00 p.m., Eastern time, on the date of the proposed Borrowing; provided
that no such notice shall be required for any deemed request of an ABR Borrowing to finance the
reimbursement of an LC Disbursement

-24-

 

as provided in Section 2.07(d). Each such
telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery,
telecopy or email to the Administrative Agent of a written Borrowing Request in substantially the
form of Exhibit B and signed by the Borrower. Each such telephonic and written Borrowing
Request shall specify the following information in compliance with Section 2.02:

               (i) the aggregate amount of the requested Borrowing;

               (ii) the date of such Borrowing, which shall be a Business Day;

               (iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

               (iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable
thereto, which shall be a period contemplated by the definition of the term “Interest Period”;

               (v) if a Revolving Borrowing is requested, the amount of the current total Revolving Credit
Exposures (without regard to the requested Revolving Borrowing) and the pro forma total Revolving
Credit Exposures (giving effect to the requested Revolving Borrowing); and

               (vi) the location and number of the Borrower’s account to which funds are to be disbursed,
which shall comply with the requirements of Section 2.05.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an
ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar
Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s
duration. Each Borrowing Request shall constitute a representation that the amount of the
requested Borrowing shall not cause (y) the total Revolving Credit Exposures to exceed the
Aggregate Revolving Commitments or (z) the total Term Credit Exposures to exceed the Aggregate Term
Commitments, as applicable.

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the
Administrative Agent shall advise each Lender of the details thereof and of the amount of such
Lender’s Loan to be made as part of the requested Borrowing.

     Section 2.04 Interest Elections.

          (a) Conversion and Continuance. Each Borrowing initially shall be of the Type
specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request. Thereafter, the Borrower
may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the
case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this
Section 2.04. The Borrower may elect different options with respect to different portions of the
affected Borrowing, in which case each such portion shall be allocated ratably
among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each
such portion shall be considered a separate Borrowing.

-25-

 

          (b) Interest Election Requests. To make an election pursuant to this Section 2.04,
the Borrower shall notify the Administrative Agent of such election by telephone by the time that a
Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing
of the Type resulting from such election to be made on the effective date of such election. Each
such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by
hand delivery or telecopy to the Administrative Agent of a written Interest Election Request in
substantially the form of Exhibit C and signed by the Borrower.

          (c) Information in Interest Election Requests. Each telephonic and written Interest
Election Request shall specify the following information in compliance with Section 2.02:

               (i) the Borrowing to which such Interest Election Request applies and, if different options
are being elected with respect to different portions thereof, the portions thereof to be allocated
to each resulting Borrowing (in which case the information to be specified pursuant to Section
2.04(c)(iii) and (iv) shall be specified for each resulting Borrowing);

               (ii) the effective date of the election made pursuant to such Interest Election Request, which
shall be a Business Day;

               (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

               (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period contemplated by
the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an
Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one
month’s duration.

          (d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an
Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof
and of such Lender’s portion of each resulting Borrowing.

          (e) Effect of Failure to Deliver Timely Interest Election Request and Event of
Default. If the Borrower fails to deliver a timely Interest Election Request with respect to a
Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such
Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be
converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing: (i) no outstanding Borrowing may be converted to or
continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion
of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be
ineffective) and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR
Borrowing at the end of the Interest Period applicable thereto.

     Section 2.05 Funding of Borrowings.

          (a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder
on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., Eastern
time, to the account of the Administrative Agent most recently designated by it for such purpose by
notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by
promptly crediting the amounts so received, in like funds, to an account of the Borrower designated
by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to
finance the reimbursement of an LC Disbursement as provided in Section 2.07(d) shall be remitted by
the Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any
Lender to obtain the funds for its Loan in any particular place or manner or to constitute a
representation by any Lender that it has obtained or will obtain the funds for its Loan in any
particular place or manner.

          (b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have
received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not
make available to the Administrative Agent such Lender’s share of such Borrowing, the
Administrative Agent may assume that such Lender has made such share available on such date in
accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the
Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the
applicable Borrowing available to the Administrative Agent, then the applicable Lender and the
Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding
amount with interest thereon, for each day from and including the date such amount is made
available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i)
in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined
by the Administrative Agent in accordance with banking industry rules on interbank compensation or
(ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays
such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan
included in such Borrowing.

     Section 2.06 Termination, Reduction and Increase of Aggregate Commitments.

          (a) Scheduled Termination of Commitments.

               (i) Unless previously terminated, the Revolving Commitments shall terminate on the Revolving
Credit Maturity Date. If at any time the Aggregate Revolving Commitments is terminated or reduced
to zero, then the Revolving Commitments shall terminate on the effective date of such termination
or reduction.

               (ii) Unless previously terminated, the Term Commitments shall terminate on the Term Loan
Funding Date.

          (b) Optional Termination and Reduction of Aggregate Credit Amounts.

               (i) The Borrower may at any time terminate, or from time to time reduce, the Aggregate
Revolving Commitments; provided that (A) each reduction of the Aggregate Revolving
Commitments shall be in an amount that is an integral multiple of $500,000 and not less than
$1,000,000 and (B) the Borrower shall not terminate or reduce the

-27-

 

Aggregate Revolving Commitments
if, after giving effect to any concurrent prepayment of the Loans in accordance with Section
3.04(c), the total Revolving Credit Exposures would exceed the Aggregate Revolving Commitments.

               (ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce
the Aggregate Revolving Commitments under Section 2.06(b)(i) at least three (3) Business Days prior
to the effective date of such termination or reduction, specifying such election and the effective
date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section
2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Revolving
Commitments shall be permanent and may not be reinstated except pursuant to Section 2.06(c). Each
reduction of the Aggregate Revolving Commitments shall be made ratably among the Revolving Lenders
in accordance with each Revolving Lender’s Applicable Percentage.

          (c) Optional Increase in Aggregate Commitments.

               (i) Subject to the conditions set forth in Section 2.06(c)(ii), the Borrower may increase the
Aggregate Revolving Commitments and/or the Aggregate Term Commitments then in effect with the prior
consent of the Administrative Agent by increasing the Revolving Commitment and/or Term Commitment
of a Lender or by causing a Person that at such time is not a Lender to become a Lender (an
“Additional Lender”).

               (ii) Any increase in the Aggregate Revolving Commitments and/or the Aggregate Term Commitments
shall be subject to the following additional conditions:

                    (A) such increase shall not be less than $25,000,000 and shall be in a whole multiple of
$5,000,000 in excess thereof unless the Administrative Agent otherwise consents, and no such
increase shall be permitted if after giving effect thereto the cumulative increases of the
Aggregate Commitments pursuant to this Section 2.06(c) would exceed $225,000,000;

                    (B) no Default shall have occurred and be continuing at the effective date of such increase;

                    (C) on the effective date of such increase, no Eurodollar Borrowings shall be outstanding or
if any Eurodollar Borrowings are outstanding, then the effective date of such increase shall be the
last day of the Interest Period in respect of such Eurodollar Borrowings unless the Borrower pays
compensation required by Section 5.02;

                    (D) no Lender’s Revolving Commitment and/or Term Commitment may be increased without the
consent of such Lender;

                    (E) if the Borrower elects to increase the Aggregate Revolving Commitments by increasing the
Revolving Commitment of a Revolving Lender, the Borrower and such Lender shall execute and deliver
to the Administrative Agent a certificate substantially in the form of Exhibit G-1 (a
“Commitment Increase Certificate”), and, if requested, the Borrower shall deliver a new
Note payable to the order of such Revolving Lender in a principal

-28-

 

amount equal to its Revolving
Commitment after giving effect to such increase, and otherwise duly completed; and

                    (F) If the Borrower elects to increase the Aggregate Revolving Commitments by causing an
Additional Lender to become a party to this Agreement, then the Borrower and such Additional Lender
shall execute and deliver to the Administrative Agent a certificate substantially in the form of
Exhibit G-2 (an “Additional Lender Certificate”), together with an Administrative
Questionnaire, and, if requested, the Borrower shall deliver a Note payable to the order of such
Additional Lender in a principal amount equal to its Revolving Commitment, and otherwise duly
completed.

                    (G) If the Borrower elects to increase the Aggregate Term Commitments, the Borrower and each
Term Loan Lender shall execute and deliver to the Administrative Agent a Term Loan Assumption
Agreement and such other documentation as the Administrative Agent shall reasonably specify to
evidence the Term Commitment of such Term Loan Lender. Each Term Loan Assumption Agreement shall
specify the Term Commitments, the Applicable Margins, the Term Loan Funding Date, and the Term Loan
Maturity Date and other terms of the Term Loans to be made thereunder; provided, that no
Term Loans shall be made unless (y) the conditions set forth in Section 6.03 shall be satisfied and
(z) the other closing certificates and documentation as required by the relevant Term Loan
Assumption Agreement shall be delivered. The Administrative Agent shall promptly notify each Term
Loan Lender as to the effectiveness of each Term Loan Assumption Agreement.

               (iii) Subject to acceptance and recording thereof pursuant to Section 2.06(c)(iv), from and
after the effective date specified in the Commitment Increase Certificate or the Additional Lender
Certificate (or if any Eurodollar Borrowings are outstanding, then the last day of the Interest
Period in respect of such Eurodollar Borrowings, unless the Borrower has paid compensation required
by Section 5.02): (A) the amount of the Aggregate Revolving Commitments and/or Aggregate Term
Commitments shall be increased as set forth therein, and (B) in the case of an Additional Lender
Certificate, any Additional Lender party thereto shall be a party to this Agreement and the other
Loan Documents and have the rights and obligations of a Lender under this Agreement and the other
Loan Documents. In addition in connection with an increase of the Aggregate Revolving Commitments,
the Lender or the Additional Lender, as applicable, shall purchase a pro rata portion of the
outstanding Revolving Loans (and participation interests in Letters of Credit) of each of the other
Revolving Lenders (and such Lenders hereby agree to sell and to take all such further action to
effectuate such sale) such that each Revolving Lender (including any Additional Lender, if
applicable) shall hold its Applicable Percentage of the outstanding Revolving Loans (and
participation interests) after giving effect to the increase in the Aggregate Revolving
Commitments.

               (iv) Upon its receipt of a duly completed Commitment Increase Certificate or an Additional
Lender Certificate, executed by the Borrower and the Lender or the
Borrower and the Additional Lender party thereto, as applicable, the Administrative
Questionnaire referred to in Section 2.06(c)(ii), if applicable, the written consent of the
Administrative Agent to such increase required by Section 2.06(c)(i), and such documents and
opinions reasonably requested by the Administrative Agent, the Administrative Agent shall accept
such Commitment Increase Certificate or Additional Lender Certificate and record the

-29-

 

information
contained therein in the Register required to be maintained by the Administrative Agent pursuant to
Section 12.04(c). No increase in the Aggregate Revolving Commitments and/or the Aggregate Term
Commitments shall be effective for purposes of this Agreement unless it has been recorded in the
Register as provided in this Section 2.06(c)(iv).

     Section 2.07 Letters of Credit.

     (a) During the period from and including the Effective Date to, but excluding, the 30th day
prior to the Revolving Credit Maturity Date, the Issuing Banks, as issuing bank for the Lenders,
agree to extend credit for the account of the Borrower at any time and from time to time by
issuing, renewing, extending or reissuing Letters of Credit; provided however, the
LC Exposure at any one time outstanding shall not exceed $20,000,000. The Revolving Lenders shall
participate in such Letters of Credit according to their respective Applicable Percentage. Each of
the Letters of Credit shall (1) be issued by the Issuing Banks on a sight basis only, (2) contain
such terms and provisions as are reasonably required by the Issuing Banks, (3) be for the account
of the Borrower and (4) expire not later than (A) 30 days before the Revolving Credit Maturity
Date, with respect to commercial letters of credit, and (B) 10 days before the Revolving Credit
Maturity Date, with respect to standby letters of credit. The Borrower may request that one or
more Letters of Credit be issued in an Offshore Currency denomination as part of the LC Exposure.
The aggregate US Dollar Equivalent of all Offshore Currency Letters of Credit, as of the issuance
date of any such Offshore Currency Letter of Credit, shall not exceed $20,000,000. No Issuing Bank
shall be obligated to issue an Offshore Currency Letter of Credit if such Issuing Bank has
determined, in its sole discretion, that it is unable to fund obligations in the requested Offshore
Currency; provided, however, the Administrative Agent shall use its best efforts to
locate suitable issuers if no Issuing Banks are able to fund obligations in the requested Offshore
Currency. From and after the Effective Date, the Existing Letters of Credit shall be deemed to be
Letters of Credit issued pursuant to this Section 2.07.

Notwithstanding anything to the contrary contained in this Agreement, including, without
limitation, this Section 2.07, the expiration date of one or more Letters of Credit may extend
beyond the Revolving Credit Maturity Date; provided, however, it is hereby
expressly agreed and understood that:

     (i) the aggregate face amount of all such Letters of Credit shall not at any time exceed
$10,000,000;

     (ii) the expiration dates of such Letters of Credit shall not extend more than three (3) years
beyond the Revolving Credit Maturity Date;

     (iii) the Borrower shall, not later than five (5) Business Days prior to the Revolving Credit
Maturity Date, deposit in an account with the Administrative Agent, in the name of the
Administrative Agent for the benefit of the Administrative Agent and the Issuing Banks, an amount
in cash equal to the aggregate face amount of all such Letters of Credit as of such date;
provided that for all Offshore Currency Letters of Credit, the Borrower shall deposit an
amount in cash equal to 110% of the aggregate face amount of all such Offshore Currency Letters of
Credit and will have a continuing obligation to maintain in such account at least an amount in cash
equal to 110% of the aggregate face amount of all such Offshore Currency Letters of Credit

-30-

 

based on
the then US Dollar Equivalent, and the Administrative Agent shall have exclusive dominion and
control (including the exclusive right of withdrawal) over such account;

     (iv) if the Issuing Banks make any disbursement in connection with a Letter of Credit after
the Revolving Credit Maturity Date, such disbursement shall be an advance on behalf of the Borrower
under this Agreement and shall be reimbursed to the Issuing Banks either (A) by the Administrative
Agent applying amounts in the cash collateral account referred to in clause (iii) above until
reimbursed in full, or (B) by the Borrower pursuant to Section 2.07(d) (except that the Borrower
shall not have the right to request that the Lenders make, and the Lenders shall not have any
obligation to make, a Loan under this Agreement after the Revolving Credit Maturity Date to fund
any such disbursement); and

     (v) all such disbursements referred to in clause (iv) of this paragraph shall be secured only
by the cash collateral referred to in clause (iii) of this paragraph and the Borrower hereby
grants, and by each deposit of such cash collateral with the Administrative Agent grants, to the
Administrative Agent a first-priority security interest in all such cash collateral, without any
further action on the part of the Issuing Banks, the Borrower, the Administrative Agent, any Lender
or any other Person now or hereafter party hereto (other than any action the Administrative Agent
reasonably deems necessary to perfect such security interest, which action the Borrower hereby
authorizes the Administrative Agent to take), until same are reimbursed in full.

If, on the later of the Revolving Credit Maturity Date or the Term Loan Maturity Date (A) the
Revolving Commitments have been terminated, (B) the Loans, all interest thereon and all other
amounts payable by the Borrower hereunder or in connection herewith (other than the LC Exposure in
connection with any Letter of Credit having an expiration date extending beyond the Revolving
Credit Maturity Date as permitted by Section 2.07(a)) have been paid in full, and (C) the
conditions set forth in clause (iii) above have been fully satisfied, then from and after such date
the following provisions of this Agreement shall not be operative: Sections 8.01 (other than
Section 8.01(a), which shall remain operative), 8.02 (except as the same may affect a Letter of
Credit), 8.03(b), 8.04, 8.05, 8.07, 8.08, 9.01, 9.02 (except for cash collateral securing Letters
of Credit), 9.03, 9.04, 9.05, 9.06, 9.08, 9.09, 9.10, 9.11, 9.12, 9.13, 9.14 and 9.15.

          (b) If, after payment in full of all Indebtedness of the Borrower under the Loan Documents
(including without limitation, reimbursement obligations with respect to Letters of Credit) and the
expiration or cancellation of all outstanding Letters of Credit, there remains any amount on
deposit in the cash collateral account referred to in clause (iii) above, the Administrative Agent
shall, within three (3) Business Days after all such Indebtedness is paid in
full and all outstanding Letters of Credit have expired or been cancelled, return such amount
to the Borrower.

          (c) Participations. In consideration and in furtherance of the foregoing, each
Revolving Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent,
for the account of the Issuing Bank, such Revolving Lender’s Applicable Percentage of each LC
Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as
provided in Section 2.07(d), or of any reimbursement payment required to be refunded to the
Borrower for any reason. Each Revolving Lender acknowledges and agrees that

-31-

 

its obligation to
acquire participations pursuant to this Section 2.07(c) 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, the reduction or termination of the Revolving Commitments, and that each such payment
shall be made without any offset, abatement, withholding or reduction whatsoever.

          (d) Reimbursement and Prepayment.

               (i) In connection with any Letter of Credit, the Borrower may make funds available for
disbursement by the Issuing Bank in connection with such Letter of Credit. In such cases, the
Issuing Bank shall use such funds which the Borrower has made available to fund such Letter of
Credit. In addition, the Borrower may give written instructions to the Issuing Bank and the
Administrative Agent to make a Loan under this Agreement to fund any Letters of Credit which may be
drawn. In all such cases, the Borrower shall give the appropriate notices required under this
Agreement for an ABR Loan or a Eurodollar Loan. If a disbursement by the Issuing Bank is made
under any Letter of Credit, in cases in which the Borrower has not either provided its own funds to
fund a draw on a Letter of Credit or given the Administrative Agent prior notice for a Loan under
this Agreement, then the Borrower shall pay to the Administrative Agent within two (2) Business
Days after notice of any such disbursement is received by the Borrower, the amount and, in the case
of any Offshore Currency Letters of Credit, the US Dollar Equivalent determined on the date of such
disbursement, of each such disbursement made by the Issuing Bank under the Letter of Credit (if
such payment is not sooner effected as may be required under this Section 2.07(d) or under other
provisions of the Letter of Credit), together with interest on the amount disbursed from and
including the date of disbursement until payment in full of such disbursed amount at a varying rate
per annum equal to (i) the then applicable interest rate for ABR Loans through the second Business
Day after notice of such disbursement is received by the Borrower and (ii) thereafter, the
Post-Default Rate for ABR Loans (but in no event to exceed the Highest Lawful Rate) for the period
from and including the third Business Day following the date of such disbursement to and including
the date of repayment in full of such disbursed amount. The obligations of the Borrower under this
Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable
and shall be paid or performed strictly in accordance with the terms of this Agreement under all
circumstances whatsoever, including, without limitation, but only to the fullest extent permitted
by applicable law, the following circumstances: (A) any lack of validity or enforceability of this
Agreement, any Letter of Credit or any of the Security Instruments; (B) any amendment or waiver of
(including any default), or any consent to departure from this Agreement (except to the extent
permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments;
(C) the existence of any claim, set-off, defense or other rights which the Borrower may have
at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of
Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), the
Issuing Bank, the Administrative Agent, any Lender or any other Person, whether in connection with
this Agreement, any Letter of Credit, the Security Instruments, the Transactions or any unrelated
transaction; (D) any statement, certificate, draft, notice or any other document presented under
any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect
or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (E)
payment by the Issuing Bank under any Letter of Credit against

-32-

 

presentation of a draft or
certificate which appears on its face to comply, but does not comply, with the terms of such Letter
of Credit; and (F) any other circumstance or happening whatsoever, whether or not similar to any of
the foregoing.

Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for
payment or performance that results from the gross negligence or willful misconduct of the Issuing
Bank or its officers, employees, agents or representatives, except where the Borrower or any
Restricted Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment
made by the Issuing Bank in connection with such gross negligence or willful misconduct, except for
reasonable costs and expenses associated with such recovery.

               (ii) In the event of the occurrence of any Event of Default, a payment or prepayment pursuant
to Section 3.04(c) or the maturity of the Notes, whether by acceleration or otherwise, an amount
equal to the LC Exposure, except for all Offshore Currency Letters of Credit which shall equal an
amount equal to 110% of the aggregate face amount of all such Offshore Currency Letters of Credit
based on the then US Dollar Equivalent, shall be deemed to be forthwith due and owing by the
Borrower to the Issuing Bank, the Administrative Agent and the Lenders as of the date of any such
occurrence; and the Borrower’s obligation to pay such amount shall be absolute and unconditional,
without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down
all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent
permitted by applicable law, shall not be subject to any defense or be affected by a right of
set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such
beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any
reason whatsoever. The Borrower will have a continuing obligation to maintain in such account at
least an amount in cash equal to 110% of the aggregate face amount of all such Offshore Currency
Letters of Credit based on the then US Dollar Equivalent. Such payments shall be held by the
Issuing Bank on behalf of the Lenders as cash collateral securing the LC Exposure in an account or
accounts at their principal office; and the Borrower hereby grants to, and by its deposit with the
Administrative Agent grants to, the Administrative Agent a security interest in such cash
collateral. In the event of any such payment by the Borrower of amounts contingently owing under
outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment
complying with the terms of such Letters of Credit are not made prior to the respective expiration
dates thereof, the Administrative Agent agrees, if no Event of Default has occurred and is
continuing or if no other amounts are outstanding under this Agreement, the Notes or the Security
Instruments, to remit to the Borrower (i) amounts for which the contingent obligations evidenced by
the Letters of Credit have ceased and (ii) amounts on deposit as cash collateral for Letters of
Credit.

               (iii) Each Revolving Lender severally and unconditionally agrees that it shall promptly
reimburse the Issuing Bank in dollars an amount equal to such Revolving Lender’s participation in
any Letter of Credit as provided in Section 2.07(a) of any disbursement made by the Issuing Bank
under any Letter of Credit that is not reimbursed according to this Section 2.07 (other than with
respect to disbursements described in the second paragraph of Section 2.07(d)(i)) and such
obligation to reimburse 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 Aggregate Revolving Commitments,
and that each such payment shall be made without

-33-

 

any offset, abatement, withholding or reduction
whatsoever. If the Borrower fails to make such payment when due, the Administrative Agent shall
notify each Revolving Lender of the applicable disbursement, the payment then due from the Borrower
in respect thereof and such Revolving Lender’s Applicable Percentage thereof. Promptly following
receipt of such notice, each Revolving Lender shall pay to the Administrative Agent its Applicable
Percentage of the payment then due from the Borrower, in the same manner as provided in Section
2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to
the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the
Issuing Bank the amounts so received by it from the Revolving 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 Issuing Bank or, to the extent that
Revolving Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then
to such Revolving Lenders and the Issuing Bank as their interests may appear. Any payment made by
a Revolving Lender pursuant to this paragraph to reimburse the Issuing Bank for any disbursement
shall constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such
disbursement.

               (iv) If no Event of Default has occurred and is continuing, and subject to availability under
the Revolving Commitments (after reduction for the LC Exposure), to the extent the Borrower has not
reimbursed the Issuing Bank for any drawn upon Letter of Credit within one (1) Business Day after
notice of such disbursement has been received by the Borrower, the amount of such Letter of Credit
reimbursement obligation shall automatically be funded by the Lenders as a Loan hereunder and used
to pay such Letter of Credit reimbursement obligation in the percentages referenced in clause (iii)
above. If an Event of Default has occurred and is continuing, or if the funding of such Letter of
Credit reimbursement obligation as a Loan would cause the aggregate amount of all Loans outstanding
to exceed the Revolving Commitments (after reduction for the LC Exposure), such Letter of Credit
reimbursement obligation shall not be funded as a Loan, but instead shall accrue interest as
provided in Section 2.07(d)(i) and be subject to reimbursement under Section 2.07(d)(iii).

          (e) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by
written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the
successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement
of the 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
3.05(a). From and after the effective date of any such replacement, (i) the successor Issuing Bank
shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to
Letters of Credit to be issued thereafter and (ii) references herein
to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous
Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require.
After the replacement of the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party
hereto and shall continue to have all the rights and obligations of the 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.

principal amount and accrued and unpaid interest under the Revolving Loans.

          (b) Term Loans. On the Term Loan Maturity Date, the Borrower shall pay to the
Administrative Agent, for the account of each Term Loan Lender, the outstanding aggregate principal

          (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear
interest at the LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable
Margin, but in no event to exceed the Highest Lawful Rate.

          (c) Post-Default Rate. Notwithstanding the foregoing, the Borrower will pay to the
Administrative Agent, for the account of each Lender, interest at the applicable Post-Default Rate
on any principal amount of any Loan made by such Lender, and (to the fullest extent permitted by
law) on any other amount payable by the Borrower hereunder, under any Loan Document or under any
Note held by such Lender to or for account of such Lender, for the period commencing on the date of
an Event of Default until the same is paid in full or all Events of Default are cured or waived.

          (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears
on each Interest Payment Date for such Loan; provided that (i) interest accrued pursuant to
Section 3.02(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any
Loan (other than an optional prepayment of an ABR Loan prior to the Revolving Credit Maturity Date
or Term Loan Maturity Date, as applicable), accrued interest on the principal amount repaid or
prepaid shall be payable on the date of such repayment or prepayment and
(iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current

the Term Loan Maturity Date.

          (e) Interest Rate Computations. All interest with respect to Eurodollar Loans
hereunder shall be computed on the basis of a year of 360 days, unless such computation would
exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of
365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of
days elapsed (including the first day but excluding the last day). All interest with respect to

-35-

 

ABR Loans hereunder shall be computed on the basis of a year of 365 days (or 366 days in a leap
year), and in each case shall be payable for the actual number of days elapsed (including the first
day but excluding the last day). The applicable Base Rate, LIBO Rate or LIBO shall be determined
by the Administrative Agent, and such determination shall be conclusive absent manifest error, and
be binding upon the parties hereto.

     Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

          (a) the Administrative Agent determines (which determination shall be conclusive absent
manifest error) that adequate and reasonable means do not exist for ascertaining the LIBO Rate or
the LIBO for such Interest Period; or

          (b) the Administrative Agent is advised by the Majority Lenders that the LIBO Rate or LIBO, as
applicable, for such Interest Period will not adequately and fairly reflect the cost to such
Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent
notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer
exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective and (ii) if any
Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR
Borrowing.

     Section 3.04 Prepayments.

          (a) Optional Prepayments. The Borrower shall have the right at any time and from time
to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with
Section 3.04(b).

          (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the
Administrative Agent by telephone (confirmed by telecopy) of any prepayment hereunder (i) in
the case of prepayment of a Eurodollar Borrowing, not later than 12:00 p.m., Eastern time,
three (3) Business Days before the date of prepayment, or (ii) in the case of prepayment of an ABR
Borrowing, not later than 12:00 p.m., Eastern time, on the date of prepayment. Each such notice
shall be irrevocable and shall specify the prepayment date and the principal amount of each
Borrowing or portion thereof to be prepaid (which shall be in integral multiples of $100,000 for
ABR Borrowings or the remaining aggregate principal balance outstanding on the applicable Notes for
ABR Borrowings and in an amount equal to all of the Eurodollar Borrowings for the Interest Period
prepaid for Eurodollar Borrowings). Promptly following receipt of any such notice relating to a
Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial
prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance
of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall
be applied ratably to the Loans included in the

-36-

 

prepaid Borrowing. Prepayments shall be
accompanied by accrued interest to the extent required by Section 3.02.

          (c) Mandatory Prepayments.

               (i) If, after giving effect to any termination or reduction of the Aggregate Revolving
Commitments pursuant to Section 2.06(b), the total Revolving Credit Exposure exceeds the Aggregate
Revolving Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such
termination or reduction in an aggregate principal amount equal to such excess, and (B) if any
excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the
Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash
collateral as provided in Section 2.07(d)(ii).

               (ii) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first,
ratably to any ABR Borrowings then outstanding, and, second, to any Eurodollar Borrowings then
outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar
Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of
days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing
with the most number of days remaining in the Interest Period applicable thereto.

               (iii) Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to
the extent required by Section 3.02. Any prepayments on the Term Loans may not be reborrowed.

          (d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04
shall be without premium or penalty, except as required under Section 5.02.

     Section 3.05 Fees.

          (a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the
account of each Revolving Lender a commitment fee, which shall accrue at the Applicable Margin (the
“Commitment Fee”) on the average daily amount of the unused amount (after deducting any LC
Exposure) of the Revolving Commitment of such Lender during the
period from and including the Effective Date to but excluding the Revolving Credit Maturity
Date. Accrued Commitment Fees shall be payable in arrears on the last day of March, June,
September and December of each year and on the Revolving Credit Maturity Date, commencing on the
first such date to occur after the date hereof. All Commitment Fees shall be computed on the basis
of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case
interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and
shall be payable for the actual number of days elapsed (including the first day but excluding the
last day).

          (b) Letter of Credit Fees. The Borrower agrees to pay (i) to the Administrative Agent
for the account of each Lender a participation fee with respect to its participations in Letters of
Credit, which shall accrue at the same Applicable Margin used to determine the interest rate
applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding
any portion thereof attributable to unreimbursed LC

-37-

 

Disbursements and including the US Dollar
Equivalent of the face amount of the outstanding Offshore Currency Letter of Credit) during the
period from and including the date of this Agreement to but excluding the later of the date on
which such Lender’s Revolving Commitment terminates and the date on which such Lender ceases to
have any LC Exposure, (ii) to the 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 (excluding any portion thereof
attributable to unreimbursed LC Disbursements) during the period from and including the date of
this Agreement to but excluding the later of the date of termination of the Aggregate Revolving
Commitments and the date on which there ceases to be any LC Exposure and (iii) to the Issuing Bank,
for its own account, its standard fees with respect to the issuance, amendment, renewal or
extension of any Letter of Credit or processing of drawings thereunder. Participation fees and
fronting fees accrued through and including the last day of March, June, September and December of
each year shall be payable on the third Business Day following such last day, commencing on the
first such date to occur after the date of this Agreement; provided that all such fees
shall be payable on the Revolving Credit Maturity Date and any such fees accruing after the
Revolving Credit Maturity Date shall be payable on demand. Any other fees payable to the Issuing
Bank pursuant to this Section 3.05(a) shall be payable within 10 days after demand. All
participation fees and fronting fees shall be computed on the basis of a year of 360 days, unless
such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on
the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual
number of days elapsed (including the first day but excluding the last day).

          (c) Administrative Agent Fees. The Borrower agrees to pay to the Administrative
Agent, for its own account, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Administrative Agent.

          (d) Other Fees. The Borrower shall pay to the Administrative Agent for its own
account such other fees as are set forth in the Fee Letter on the dates specified therein to the
extent not paid prior to the Effective Date.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs

     Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

          (a) Payments by the Borrower. The Borrower shall make each payment required to be
made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or
of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00
p.m., Eastern time, on the date when due, in immediately available funds, without defense,
deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall
not be refundable under any circumstances. Any amounts received after such time on any date may,
in the discretion of the Administrative Agent, be deemed to have been received on the next
succeeding Business Day for purposes of calculating interest thereon. All such payments shall be
made to the Administrative Agent as specified in Section 12.01, except payments to be made directly
to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01,
Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled
thereto. The Administrative Agent shall distribute any such

-38-

 

payments received by it for the
account of any other Person to the appropriate recipient promptly following receipt thereof. If
any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall
be extended to the next succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments hereunder shall
be made in dollars.

          (b) Application of Insufficient Payments. If at any time insufficient funds are
received by and available to the Administrative Agent to pay fully all amounts of principal,
unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of interest and fees then due to such parties and
(ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder,
ratably among the parties entitled thereto in accordance with the amounts of principal and
unreimbursed LC Disbursements then due to such parties.

          (c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of
set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on
any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment
of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements
and accrued interest thereon than the proportion received by any other Lender, then the Lender
receiving such greater proportion shall purchase (for cash at face value) participations in the
Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the
benefit of all such payments shall be shared by the Lenders ratably in accordance with the
aggregate amount of principal of and accrued interest on their respective Loans and participations
in LC Disbursements; provided that (i) if any such participations are purchased and all or
any portion of the payment giving rise thereto is recovered, such participations shall be rescinded
and the purchase price restored to the extent of such recovery, without interest and (ii) the
provisions of this Section 4.01(c) shall not be construed to apply to
any payment made by the Borrower pursuant to and in accordance with the express terms of this
Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans or participations in LC Disbursements to any assignee or
participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the
provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and
agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against the Borrower rights of
set-off and counterclaim with respect to such participation as fully as if such Lender were a
direct creditor of the Borrower in the amount of such participation.

     Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date
on which any payment is due to the Administrative Agent for the account of the Lenders or the
Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that
the Borrower has made such payment on such date in accordance herewith and may, in reliance upon
such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due.
In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the
Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith
on demand the amount so distributed to such Lender or Issuing Bank with interest

-39-

 

thereon, for each
day from and including the date such amount is distributed to it to but excluding the date of
payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate
determined by the Administrative Agent in accordance with banking industry rules on interbank
compensation.

     Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section
2.05(b), Section 2.07(c), Section 2.07(d) or Section 4.02 then the Administrative Agent may, in its
discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received
by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations
under such Sections until all such unsatisfied obligations are fully paid.

     Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in
favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s or each
Guarantor’s interest in and to production and all proceeds attributable thereto which may be
produced from or allocated to the Property. The Security Instruments further provide in general
for the application of such proceeds to the satisfaction of the Indebtedness and other obligations
described therein and secured thereby. Notwithstanding the assignment contained in such Security
Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the
Lenders agree that they will neither notify the purchaser or purchasers of such production nor take
any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders,
but the Lenders will instead permit such proceeds to be paid to the Borrower and its Subsidiaries
and (b) the Lenders hereby authorize the Administrative Agent to
take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such
Subsidiaries.

ARTICLE V

Increased Costs; Break Funding Payments; Taxes; Illegality

     Section 5.01 Increased Costs.

          (a) Eurodollar Changes in Law. If any Change in Law shall:

               (i) impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of, or credit extended by, any
Lender (except any such reserve requirement reflected in the LIBO Rate); or

               (ii) impose on any Lender or the London interbank market any other condition affecting this
Agreement or Eurodollar Loans made by such Lender;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or
maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to
reduce the amount of any sum received or receivable by such Lender (whether of principal, interest
or otherwise), then the Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

          (b) Capital Requirements. If any Lender or the Issuing Bank determines that
any Change in Law regarding capital requirements has or would have the effect of reducing the

-40-

 

rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the
Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or
participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the
Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the
Issuing Bank’s holding company could have achieved but for such Change in Law (taking into
consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the
Issuing Bank’s holding company with respect to capital adequacy), then from time to time the
Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or
amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s
holding company for any such reduction suffered.

          (c) Certificates. A certificate of a Lender or the Issuing Bank setting
forth in reasonable detail the amount or amounts necessary to compensate such Lender or the Issuing
Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be
delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such
certificate within thirty (30) days after receipt thereof.

          (d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the
part of any Lender or the Issuing Bank to demand compensation pursuant to this Section
5.01 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such
compensation.

     Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last
day of an Interest Period applicable thereto (including as a result of an Event of Default), (b)
the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest
Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar
Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any
Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of
a request by the Borrower pursuant to Section 5.04(b), then, in any such event, the Borrower shall
compensate each Lender for the loss, cost and expense attributable to such event. In the case of a
Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount
determined by such Lender to be the excess, if any, of (i) the amount of interest which would have
accrued on the principal amount of such Loan had such event not occurred, at the LIBO Rate that
would have been applicable to such Loan, for the period from the date of such event to the last day
of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or
continue, for the period that would have been the Interest Period for such Loan), over (ii) the
amount of interest which would accrue on such principal amount for such period at the interest rate
which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits
of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to
receive pursuant to this Section 5.02 shall be delivered to the Borrower and shall be conclusive
absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such
certificate within ten (10) days after receipt thereof.

-41-

 

     Section 5.03 Taxes.

          (a) Payments Free of Taxes. Any and all payments by or on account of any
obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of
and without deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that after making all
required deductions (including deductions applicable to additional sums payable under this Section
5.03(a)), the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, (ii) the Borrower or such
Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full
amount deducted to the relevant Governmental Authority in accordance with applicable law.

          (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to
the relevant Governmental Authority in accordance with applicable law.

          (c) Indemnification by the Borrower. The Borrower shall indemnify the
Administrative Agent, each Lender and the Issuing Bank, within ten (10) days after written
demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the
Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to
any payment by or on account of any obligation of the Borrower hereunder (including Indemnified
Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section
5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect
thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or
asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a
Lender or the Issuing Bank as to the amount of such payment or liability under this Section 5.03
shall be delivered to the Borrower and shall be conclusive absent manifest error.

          (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the
Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt
issued by such Governmental Authority evidencing such payment, a copy of the return reporting such
payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

          (e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption
from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is
located, or any treaty to which such jurisdiction is a party, with respect to payments under this
Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such properly completed
and executed documentation prescribed by applicable law or reasonably requested by the Borrower as
will permit such payments to be made without withholding or at a reduced rate.

          (f) Tax Refunds. If the Administrative Agent or a Lender determines, in its sole
discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been

-42-

 

indemnified by the Borrower or with respect to which the Borrower has paid additional amounts
pursuant to this Section 5.03, it shall pay over such refund to the Borrower (but only to the
extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section
5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket
expenses of the Administrative Agent or such Lender and without interest (other than any interest
paid by the relevant Governmental Authority with respect to such refund); provided, that
the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the
amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) to the Administrative Agent or such Lender in the event the
Administrative Agent or such Lender is required to repay such refund to such Governmental
Authority. This Section 5.03 shall not be construed to require the Administrative Agent or any
Lender to make available its tax returns (or any other information relating to its taxes which it
deems confidential) to the Borrower or any other Person.

     Section 5.04 Mitigation Obligations; Replacement of Lenders.

          (a) Designation of Different Lending Office. If any Lender requests compensation
under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or
any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender
shall use reasonable efforts to designate a different lending office for funding or booking its
Loans hereunder or to assign its rights and obligations hereunder to another of its offices,
branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i)
would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may
be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and
would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all
reasonable costs and expenses incurred by any Lender in connection with any such designation or
assignment.

          (b) Replacement of Lenders. If any Lender requests compensation under Section 5.01,
or if the Borrower is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 5.03, or if any Lender defaults in its
obligation to fund Loans hereunder, then the Borrower may, at its sole expense and effort, upon
notice to such Lender and the Administrative Agent, require such Lender to assign and delegate,
without recourse (in accordance with and subject to the restrictions contained in Section
12.04(c)), all its interests, rights and obligations under this Agreement to an assignee that shall
assume such obligations (which assignee may be another Lender, if a Lender accepts such
assignment); provided that (i) the Borrower 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 Loans 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 Borrower (in the case of all other amounts) and (iii) in the case of any
such assignment resulting from a claim for compensation under Section 5.01 or payments required to
be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation
or payments. A Lender shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the
Borrower to require such assignment and delegation cease to apply.

-43-

 

     Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for
any Lender or its Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall
promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to
make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as
such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which
would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so
requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender
then outstanding shall be automatically converted into ABR
Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans
are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be
applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

represents and warrants with respect to itself, as applicable, to the Administrative Agent, the
Issuing Bank and the Lenders (each representation and warranty herein is given as of

-47-

 

the Effective
Date and shall be deemed repeated and reaffirmed on the dates of each Borrowing and issuance,
renewal, extension or reissuance of a Letter of Credit as provided in Section 6.02):

     Section 7.01 Legal Existence. With respect to itself and each of its Material Domestic Subsidiaries: (a) is a legal entity
duly organized, legally existing and in good standing (if applicable) under the laws of the

requisite power, and has all material governmental licenses, authorizations, consents and approvals
necessary to own its assets and carry on its business as now being or as proposed to be conducted;
and (c) is qualified to do business in all jurisdictions in which the nature of the business
conducted by it makes such qualification necessary and where failure so to qualify would result in
a Material Adverse Effect.

     Section 7.02 Financial Condition. There has been no change or event having a Material Adverse Effect from the financial condition
of UCLP and its Consolidated Subsidiaries set forth on the pro forma balance sheet dated as of June
30, 2006 in the S-1.

     Section 7.03 Litigation. Except as disclosed to the Lenders in Schedule 7.03 hereto, at the Effective Date there
is no litigation, legal, administrative or arbitral proceeding, investigation or other action of
any nature pending or, to its knowledge threatened against or affecting it or any of its
Subsidiaries which involves the possibility of any judgment or liability against it or any of its
Subsidiaries which would reasonably be expected to have a Material Adverse Effect.

     Section 7.04 No Breach. Neither the execution and delivery of the Loan Documents, nor compliance with the terms and
provisions hereof will conflict with or result in a breach of, or require any consent which has not
been obtained as of the Effective Date under, the respective charter or by-laws of it or any of its
Restricted Subsidiaries, or any Governmental Requirement or any agreement or instrument to which it
or any of its Restricted Subsidiaries is a party or by which it is bound or to which it or its
Properties are subject, or constitute a default under any such agreement or instrument, or result
in the creation or imposition of any Lien upon any of the revenues or assets of it or any of its
Restricted Subsidiaries pursuant to the terms of any such agreement or instrument other than the
Liens created by the Loan Documents.

     Section 7.05 Authority. It and each of its Restricted Subsidiaries have all necessary power and authority to execute,
deliver and perform its obligations under the Loan Documents to which it is a party; and the
execution, delivery and performance by it and each Restricted Subsidiary of the Loan Documents to
which it is a party, have been duly authorized by all necessary action on its part; and the Loan
Documents constitute the legal, valid and binding obligations of it and each of its Restricted
Subsidiaries, enforceable in accordance with their terms, except to the extent that the
enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws generally affecting creditors’ rights and by equitable principles
(regardless of whether enforcement is sought in equity or at law).

     Section 7.06 Approvals. No authorizations, approvals or consents of, and no filings or registrations with, any
Governmental Authority are necessary for the execution, delivery or performance by it or any of its
Restricted Subsidiaries of the Loan Documents or for the validity

-48-

 

or enforceability thereof, except
for the recording and filing of the Security Instruments as required by this Agreement.

     Section 7.07 Use of Loans and Letters of Credit.

          (a) Revolving Loans and Letters of Credit. The Borrower will use the proceeds of the
Loans and Letters of Credit for acquisitions permitted hereunder, to repay debt which is assumed in
connection with such acquisitions, to pay distributions, for working capital, and other general
corporate purposes not in contravention of any Governmental Requirement or of any Loan Document.

          (b) Term Loans. The Borrower will use the proceeds of the Term Loans for acquisitions
permitted hereunder, to repay debt which is assumed in connection with such acquisitions, to pay
distributions, for working capital, and other general corporate purposes not in contravention of
any Governmental Requirement or of any Loan Document.

          (c) Margin Stock. The Borrower is not engaged principally, or as one of its important
activities, in the business of extending credit for the purpose, whether immediate, incidental or
ultimate, of buying or carrying margin stock (within the meaning of Regulation T, U or X of the
Board of Governors of the Federal Reserve System) and no part of the proceeds of any Loan hereunder
will be used to buy or carry any margin stock.

     Section 7.08 ERISA . No ERISA Event has occurred or is reasonably expected to occur that, when taken together
with all other such ERISA Events for which liability is reasonably expected to occur, could
reasonably be expected to result in a Material Adverse Effect. The present value of all
accumulated benefit obligations under each Plan (based on the assumptions used for purposes of
Statement of Financial Accounting Standards No. 87) did not, as of the date of the most recent
financial statements reflecting such amounts, exceed by more than $100,000 the fair market value of
the assets of such Plan, and the present value of all accumulated benefit obligations of all
underfunded Plans (based on the assumptions used for purposes of Statement of Financial Accounting
Standards No. 87) did not, as of the date of the most recent financial statements reflecting such
amounts, exceed by more than $100,000 the fair market value of the assets of all such underfunded
Plans.

     Section 7.09 Taxes. Except as set out in Schedule 7.09, it and its Domestic Subsidiaries have filed all
United States Federal income tax returns and all other tax returns which are required to be filed
by them and have paid all taxes due pursuant to such returns or pursuant to any assessment received
by it or any of its Domestic Subsidiaries, except where the failure to file such tax returns and
pay such taxes would not result in a liability in excess of $5,000,000 in the aggregate. The
charges, accruals and reserves on the books of it and its Domestic Subsidiaries in respect of taxes
and other governmental charges are, in the opinion of it, adequate. No tax lien has been filed and, to
the knowledge of it, no claim is being asserted with respect to any such tax, fee or other charge
which would result in a liability in excess of $5,000,000 in the aggregate.

-49-

 

     Section 7.10 Titles, Etc.

     (a) Except as set out in Schedule 7.10, it and its Restricted Subsidiaries have good
and marketable title to their material Properties, (i) except in cases where the failure to have
said good and marketable title would not result in a Material Adverse Effect and (ii) free and
clear of all Liens, except Liens permitted by Section 9.02.

     (b) All leases and agreements necessary for the conduct of the business of it and its
Restricted Subsidiaries are valid and subsisting, in full force and effect and there exists no
default or event or circumstance which with the giving of notice or the passage of time or both
would give rise to a default under any such lease or agreement and which default, event or
circumstance would result in a Material Adverse Effect.

     Section 7.11 No Material Misstatements. No written information, statement, exhibit, certificate, document or report furnished to the
Administrative Agent and the Lenders (or any of them) by it or any of its Restricted Subsidiaries
in connection with the negotiation of this Agreement, including the Information Memorandum, or
delivered hereunder (as modified or supplemented by other information so furnished) contains any
material misstatement of fact or omits to state a material fact necessary to make the statements
contained therein not materially misleading in the light of the circumstances in which made and
with respect to it and its Restricted Subsidiaries taken as a whole. To its knowledge, there is no
fact peculiar to it or any of its Restricted Subsidiaries which has a Material Adverse Effect and
which has not been set forth in this Agreement or the other documents, certificates and statements
furnished to the Administrative Agent by or on behalf of it or any of its Restricted Subsidiaries
or otherwise prior to, or on, the Effective Date in connection with the Transactions contemplated
hereby.

     Section 7.12 Investment Company Act. Neither UCLP nor any of its Subsidiaries is an “investment company” or a company “controlled” by
an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

     Section 7.13 Subsidiaries. Except as set out in Schedule 7.13, as of the Effective Date, UCLP has no Subsidiaries.

     Section 7.14 Location of Business and Offices. The Borrower’s principal place of business and chief executive office is located at the

     Section 7.15 Defaults. Neither it nor any of its Restricted Subsidiaries is in material default nor has any event or

notice, or both, would constitute a material default under any material agreement or instrument to
which it or any of its Restricted Subsidiaries is a party or by which it or any of its Restricted
Subsidiaries is bound, which default would result in a Material Adverse Effect. No Default
hereunder has occurred and is continuing.

     Section 7.16 Environmental Matters. Except (a) as provided in a notice to all Lenders or (b) as would not have a Material Adverse
Effect:

-50-

 

     (i) Neither any Property of it or any of its Subsidiaries nor the operations conducted thereon
violate any order or requirement of any court or Governmental Authority or any Environmental Laws;

     (ii) Without limitation of clause (i) above, no Property of it or any of its Subsidiaries nor
the operations currently conducted thereon or, to the best knowledge of it, by any prior owner or
operator of such Property or operation, are in violation of or subject to any existing, pending or
threatened action, suit, investigation, inquiry or proceeding by or before any court or
Governmental Authority or to any remedial obligations under Environmental Laws;

     (iii) All notices, permits, licenses or similar authorizations, if any, required to be
obtained or filed in connection with the operation or use of any and all Property of it and each of
its Subsidiaries, including without limitation, past or present treatment, storage, disposal or
release of a hazardous substance or solid waste into the environment, have been duly obtained or
filed, and it and each of its Subsidiaries are in compliance with the terms and conditions of all
such notices, permits, licenses and similar authorizations;

     (iv) All hazardous substances, solid waste, and oil and gas exploration and production wastes,
if any, generated at any and all Property of it or any of its Subsidiaries have in the past been
transported, treated and disposed of in accordance with Environmental Laws and so as not to pose an
imminent and substantial endangerment to public health or welfare or the environment, and, to the
best knowledge of it, all such transport carriers and treatment and disposal facilities have been
and are operating in compliance with Environmental Laws and so as not to pose an imminent and
substantial endangerment to public health or welfare or the environment, and are not the subject of
any existing, pending or threatened action, investigation or inquiry by any Governmental Authority
in connection with any Environmental Laws;

     (v) It has taken all steps reasonably necessary to determine and has determined that no
hazardous substances, solid waste, or oil and gas exploration and production wastes, have been
disposed of or otherwise released and there has been no threatened release of any hazardous
substances on or to any Property of it or any of its Subsidiaries except in compliance with
Environmental Laws and so as not to pose an imminent and substantial endangerment to public health
or welfare or the environment;

     (vi) To the extent applicable, all Property of it and each of its Subsidiaries currently
satisfies all design, operation, and equipment requirements imposed by the OPA or scheduled as of
the Effective Date to be imposed by OPA during the term of this Agreement, and it does not have any
reason to believe that such Property, to the extent subject to OPA, will not be able to maintain
compliance with the OPA requirements during the term of this Agreement; and

     (vii) Neither it nor any of its Subsidiaries has any known contingent liability in connection
with any release or threatened release of any oil, hazardous substance or solid waste into the
environment.

     Section 7.17 Compliance with the Law. Neither it nor any of its Subsidiaries has violated any Governmental Requirement or failed to
obtain any license, permit, franchise or other governmental authorization necessary for the
ownership of any of its Properties or the

-51-

 

conduct of its business, which violation or failure would
(in the event such violation or failure were asserted by any Person through appropriate action)
result in a Material Adverse Effect.

     Section 7.18 Insurance. The notice provided to all Lenders contains an accurate description of all material policies of
fire, liability, workmen’s compensation and other forms of insurance owned or held by UCLP and each
Material Domestic Subsidiary and Material Foreign Subsidiary. All such policies are in full force
and effect, all premiums with respect thereto covering all periods up to and including the
Effective Date have been paid, and no notice of cancellation or termination has been received with
respect to any such policy. Such policies are sufficient for compliance with all requirements of
law and of all agreements to which UCLP or any Material Domestic Subsidiary is a party; are valid,
outstanding and enforceable policies; provide adequate insurance coverage in at least such amounts
and against at least such risks (but including in any event public liability) as are usually
insured against in the same general area by companies engaged in the same or a similar business for
the assets and operations of UCLP and each Material Domestic Subsidiary; will remain in full force
and effect through the respective dates set forth in the binders for said insurance without the
payment of additional premiums; and will not in any way be affected by, or terminate or lapse by
reason of, the Transactions contemplated by this Agreement. Neither UCLP nor any Material Domestic
Subsidiary has been refused any insurance with respect to its assets or operations, nor has its
coverage been limited below usual and customary policy limits, by an insurance carrier to which it
has applied for any such insurance or with which it has carried insurance during the last three
years.

     Section 7.19 Hedging Agreements. Schedule 7.19 sets out, as of the Effective Date, a true and complete list of all
Hedging Agreements (including commodity price swap agreements, forward agreements or contracts of
sale which provide for prepayment for deferred shipment or delivery of oil, gas or other
commodities) of it and each of its Restricted Subsidiaries, the material terms thereof (including
the type, term, effective date, termination date and notional amounts or volumes), the net mark-
to-market value thereof, all credit support agreements relating thereto (including any margin
required or supplied), and the counter party to each such agreement.

     Section 7.20 Restriction on Liens. Except as set out in Schedule 7.20, neither it nor any of its Restricted Subsidiaries is
a party to any agreement or arrangement (other than this Agreement and the Security Instruments),
or subject to any order, judgment, writ or decree, which either restricts or purports to restrict
its ability to grant Liens pursuant to this Agreement and the Security Instruments to other Persons
on or in respect of its material Properties.

or to correct any omissions in the Security Instruments, or to state more fully the security
obligations set out herein or in any of the Security Instruments, or to perfect, protect or

     (a) Guarantees and Collateral. UCLP shall and it shall cause the Borrower and each
Guarantor to grant a Lien pursuant to the Security Instruments on substantially all of its
Properties located in the United States now owned or at any time hereafter acquired by it, the
Borrower or a Guarantor, including, without limitation, all Equipment, Accounts, Chattel Paper,
Documents, General Intangibles, Instruments, and Inventory; provided that the foregoing
shall not require the creation or perfection of pledges of, security interests in or mortgages on,
with respect to (A) any real property that has a value of less than $7,500,000, (B) any Property as
provided on Schedule 8.07 or (C) any Property that in the judgment of the Administrative

Property would be excessive in view of the benefits to be obtained by the Lenders therefrom,
provided further that UCLP, the Borrower and any Guarantor will have ninety (90)
days to perfect Liens on Property acquired in an acquisition. UCLP shall, and it shall promptly
cause the GP and each Significant Domestic Subsidiary now existing or hereafter formed or acquired
to, guarantee the Indebtedness pursuant to the execution and delivery of the Guaranty Agreement or
a supplement thereto. UCLP shall cause to be pledged by the appropriate Person (i) all of the
Equity Interests of each Domestic Subsidiary (including, without limitation, to the extent
certificated, delivery of original stock certificates or other certificates evidencing the capital
stock of such entity, together with an appropriate undated stock power for each certificate duly
executed in blank by the registered owner thereof), (ii) 65% of the capital stock of each first
tier Foreign Subsidiary (including, without limitation, to the extent certificated, delivery of
original stock certificates or other certificates evidencing the capital stock of such Domestic
Subsidiary or 65% of the capital stock of such Foreign Subsidiary, together with an appropriate
undated stock power for each certificate duly executed in blank by the registered owner thereof)
and (iii) and execute and deliver such other additional documents and certificates as shall
reasonably be requested by the Administrative Agent. If there are no adverse tax consequences to
UCLP, to UCLP’s partners or to any of its Restricted Subsidiaries, the Collateral described above
(and subject to the same limitations set forth above) will include Property located in
jurisdictions outside the United States, Foreign Subsidiaries will be included as Guarantors, and
all of the Equity Interest of Foreign Subsidiaries will be pledged.

Collateral that is sold, leased, assigned, conveyed, transferred or otherwise disposed of in
compliance with Sections 9.06, 9.08 and 9.11; provided that so long as the lien in favor of
the Administrative Agent continues in the proceeds of such sale, lease, assignment, conveyance,
transfer or other disposal of such Collateral, or to the extent such Collateral is sold, leased,
assigned, conveyed, transferred or otherwise disposed of to the Borrower or any Guarantor, such
lien continues in such Collateral. All Collateral shall be released upon either the Borrower’s or
UCLP’s Index Debt receiving (i) an investment grade rating from Moody’s or S&P and a rating no
lower than one notch below investment grade from the other agency and (ii) a stable outlook or
better from both Moody’s and S&P.

of, and the accrued interest on, the Loans and all other amounts payable by the Borrower hereunder
and under the Notes (including without limitation the payment of cash collateral to secure the LC
Exposure as provided in Section 2.07(d)(ii)) to be forthwith due and payable, whereupon such

to accelerate, notice of acceleration or other formalities of any kind, all of which are hereby
expressly waived by the Borrower.

     (b) In the case of the occurrence of an Event of Default referred to in clauses (f) or (g) of
Section 10.01, the Aggregate Commitments shall be automatically canceled and the principal amount

ARTICLE XI

The Agents

     Section 11.01 Appointment; Powers. Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as
its agent and authorizes the Administrative Agent to take such actions on its behalf and to
exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other
Loan Documents, together with such actions and powers as are reasonably incidental thereto.

     Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set
forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the
Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of
whether a Default has occurred and is continuing (the use of the term “agent” herein and in the
other Loan Documents with reference to the Administrative Agent is not intended to connote any
fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable
law; rather, such term is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship between independent contracting parties), (b) the
Administrative Agent shall have no duty to take any discretionary action or exercise any
discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth
herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for
the failure to disclose, any information relating to UCLP or any of its Subsidiaries that is
communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates
in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default
unless and until written notice thereof is given to the Administrative Agent by the Borrower or a
Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any
statement, warranty or representation made in or in connection with this Agreement or any other
Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder
or under any other Loan Document or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set forth herein or in
any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this
Agreement, any other Loan Document or any other agreement, instrument or document, (v) the
satisfaction of any condition set forth in ARTICLE VI or elsewhere herein, other than to confirm
receipt of items expressly required to be delivered to the Administrative Agent or as to those
conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the

-66-

 

existence, value, perfection or priority of any collateral security or the financial or other
condition of UCLP and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by
UCLP, the Borrower or any other Person (other than itself) to perform any of its obligations
hereunder or under any other Loan Document or the performance or observance of any covenants,
agreements or other terms or conditions set forth herein or therein. For purposes of determining
compliance with the conditions specified in ARTICLE VI, each Lender shall be deemed to have
consented to, approved or accepted or to be satisfied with, each document or other matter required
thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the
Administrative Agent shall have received written notice from such Lender prior to the proposed
closing date specifying its objection thereto.

     Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no duty to take any discretionary action or exercise any
discretionary powers, except discretionary rights and powers expressly contemplated hereby or by
the other Loan Documents that the Administrative Agent is required to exercise in writing as
directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be
necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative
Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan
Documents unless it shall (a) receive written instructions from the Majority Lenders or the
Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary
under the circumstances as provided in Section 12.02) specifying the action to be taken and (b) be
indemnified to its satisfaction by the Lenders against any and all liability and expenses which may
be incurred by it by reason of taking or continuing to take any such action. The instructions as
aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall
be binding on all of the Lenders. If a Default has occurred and is continuing, then the
Administrative Agent shall take such action with respect to such Default as shall be directed by
the requisite Lenders in the written instructions (with indemnities) described in this Section
11.03, provided that, unless and until the Administrative Agent shall have received such
directions, the Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default as it shall deem advisable in the
best interests of the Lenders. In no event, however, shall the Administrative Agent be required to
take any action which exposes the Administrative Agent to personal liability or which is contrary
to this Agreement, the Loan Documents or applicable law. If a Default has occurred
and is continuing, neither the Syndication Agent nor the Co-Documentation Agents shall have any
obligation to perform any act in respect thereof. The Administrative Agent shall not be liable for
any action taken or not taken by it with the consent or at the request of the Majority Lenders or
the Lenders (or such other number or percentage of the Lenders as shall be necessary under the
circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be
liable for any action taken or not taken by it hereunder or under any other Loan Document or under
any other document or instrument referred to or provided for herein or therein or in connection
herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or
willful misconduct.

     Section 11.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for
relying upon, any notice, request, certificate, consent, statement, instrument, document or other
writing believed by it to be genuine and to have been signed or sent by the proper Person. The
Administrative Agent also may rely

-67-

 

upon any statement made to it orally or by telephone and
believed by it to be made by the proper Person, and shall not incur any liability for relying
thereon and each of UCLP, the Borrower, the Lenders and the Issuing Bank hereby waives the right to
dispute the Administrative Agent’s record of such statement, except in the case of gross negligence
or willful misconduct by the Administrative Agent. The Administrative Agent may consult with legal
counsel (who may be counsel for UCLP or the Borrower), independent accountants and other experts
selected by it, and shall not be liable for any action taken or not taken by it in accordance with
the advice of any such counsel, accountants or experts. The Administrative Agent may deem and
treat the payee of any Note as the holder thereof for all purposes hereof unless and until a
written notice of the assignment or transfer thereof permitted hereunder shall have been filed with
the Administrative Agent.

     Section 11.05 Subagents. The Administrative Agent may perform any and all its duties and exercise its rights and powers
by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative
Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers
through their respective Related Parties. The exculpatory provisions of the preceding Sections of
this ARTICLE XI shall apply to any such sub-agent and to the Related Parties of the Administrative
Agent and any such sub-agent, and shall apply to their respective activities in connection with the
syndication of the credit facilities provided for herein as well as activities as Administrative
Agent.

     Section 11.06 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in
this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, the
Issuing Bank and the Borrower, and the Administrative Agent 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, in consultation with the Borrower, to appoint a successor. If no successor
shall have been so appointed by the Majority Lenders and shall have accepted such appointment
within 30 days after the retiring Agent gives notice of its resignation or
removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders and the
Issuing Bank, appoint a successor Agent. Upon the acceptance of its appointment as Agent hereunder
by a successor, such successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its
duties and obligations hereunder. The fees payable by UCLP and the Borrower to a successor Agent
shall be the same as those payable to its predecessor unless otherwise agreed between UCLP or the
Borrower and such successor. After the Agent’s resignation hereunder, the provisions of this
ARTICLE XI and Section 12.03 shall continue in effect for the benefit of such retiring Agent, its
sub-agents and their respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while it was acting as Agent.

     Section 11.07 Agents as Lenders. Each bank serving as an Agent hereunder shall have the same rights and powers in its capacity as
a Lender as any other Lender and may exercise the same as though it were not an Agent, and such
bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of
business with UCLP or any Subsidiary or other Affiliate thereof as if it were not an Agent
hereunder.

-68-

 

     Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative
Agent, any other Agent or any other Lender and based on such documents and information as it has
deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each
other Loan Document to which it is a party. Each Lender also acknowledges that it will,
independently and without reliance upon the Administrative Agent, any other Agent or any other
Lender and based on such documents and information as it shall from time to time deem appropriate,
continue to make its own decisions in taking or not taking action under or based upon this
Agreement, any other Loan Document, any related agreement or any document furnished hereunder or
thereunder. The Agents shall not be required to keep themselves informed as to the performance or
observance by UCLP or any of its Subsidiaries of this Agreement, the Loan Documents or any other
document referred to or provided for herein or to inspect the Properties or books of UCLP or its
Subsidiaries. Except for notices, reports and other documents and information expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or the Joint Lead
Arrangers shall have any duty or responsibility to provide any Lender with any credit or other
information concerning the affairs, financial condition or business of UCLP or the Borrower (or any
of their Affiliates) which may come into the possession of such Agent or any of its Affiliates. In
this regard, each Lender acknowledges that Vinson & Elkins L.L.P. is acting in this transaction as
special counsel to the Administrative Agent only, except to the extent otherwise expressly stated
in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal
counsel to the extent that it deems necessary in connection with the Loan Documents and the matters
contemplated therein.

     Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial proceeding relative to UCLP
or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any
Loan shall then be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall
be entitled and empowered, by intervention in such proceeding or otherwise:

          (a) to file and prove a claim for the whole amount of the principal and interest owing and
unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file
such other documents as may be necessary or advisable in order to have the claims of the Lenders
and the Administrative Agent (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Lenders and the Administrative Agent and their respective agents
and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03)
allowed in such judicial proceeding; and

          (b) to collect and receive any monies or other property payable or deliverable on any such
claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Lender to make such payments to the
Administrative Agent and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the
reasonable compensation, expenses, disbursements and advances of the Administrative Agent

-69-

 

and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement,
adjustment or composition affecting the Indebtedness or the rights of any Lender or to authorize
the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

     Section 11.10 Authority of Administrative Agent to Release Collateral and Liens. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any
collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents.
Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver
to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens,
termination statements, assignments or other documents reasonably requested by the Borrower in
connection with any sale or other disposition of Property to the extent such sale or other
disposition is permitted by the terms of Section 9.11 or is otherwise authorized by the terms of
the Loan Documents.

     Section 11.11 The Joint Lead Arrangers, the Syndication Agent and the Co-Documentation
Agents. The Joint Lead Arrangers, the Syndication Agent and the Co-Documentation Agents shall have no
duties, responsibilities or liabilities under this Agreement and the other Loan Documents other
than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

ARTICLE XII

Miscellaneous

     Section 12.01 Notices. All notices and other communications provided for herein and in the other Loan Documents
(including, without limitation, any modifications of, or waivers or consents under, this Agreement
or the other Loan Documents) shall be given or made by telex, telecopy, courier, U.S. Mail or in
writing and telexed, telecopied, mailed or delivered to the intended recipient at the “Address for
Notices” specified below its name on the signature pages hereof or in the other Loan Documents,
except that for notices and other communications to the Administrative Agent other than payment of
money, the Borrower need only send such notices and communications to the Administrative Agent care
of the Houston address of Wachovia; or, as to any party, at such other address as shall be
designated by such party in a notice to each other party. Except as otherwise provided in this
Agreement or in the other Loan Documents, all such communications shall be deemed to have been duly
given when transmitted, if transmitted before 1:00 p.m. local time on a Business Day (otherwise on
the next succeeding Business Day) by telex or telecopier and evidence or confirmation of receipt is
obtained, or personally delivered or, in the case of a mailed notice, three (3) Business Days after
the date deposited in the mails, postage prepaid, in each case given or addressed as aforesaid.

     Section 12.02 Waivers; Amendments.

          (a) No failure on the part of the Administrative Agent, any other Agent, the Issuing Bank or
any Lender to exercise and no delay in exercising, and no course of
dealing with 

-70-

 

respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right,
power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall
any single or partial exercise of any right, power or privilege under any of the Loan Documents
preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. The rights and remedies of the Administrative Agent, any other Agent, the Issuing Bank
and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive
of any rights or remedies that they would otherwise have. No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by UCLP or the Borrower therefrom
shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then
such waiver or consent shall be effective only in the specific instance and for the purpose for
which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of
a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the
Administrative Agent, any other Agent, any Lender or the Issuing Bank may have had notice or
knowledge of such Default at the time.

          (b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any
provision thereof may be amended, modified or waived except with the Borrower’s and the Majority
Lenders’ prior written consent or by the Borrower and the Administrative Agent’s consent with the
consent of the Majority Lenders; provided that (i) no amendment, modification or waiver
that forgives or reduces the principal amount of any Indebtedness or Letter of Credit reimbursement
obligation outstanding under this Agreement, releases all or substantially all of the Collateral
(excluding sales of Properties permitted hereunder) or the Guarantors, affects Sections 4.01,
10.02(c), 12.02 or 12.04 or permits an Interest Period with a duration in excess of six months or
modifies the definition of “Majority Lenders” shall be effective without consent of all
Lenders; (ii) no amendment, modification or waiver which extends any scheduled payment date or the
final maturity of the Term Loans, reduces the interest rate applicable to the Term Loans or the
fees payable to the Term Loan Lenders or extends the time for payment of such interest or fees
shall be effective without the consent of all the Term Loan Lenders (in lieu of the consent of the
Majority Lenders); (iii) no amendment, modification or waiver which extends any scheduled payment
date or the Revolving Credit Maturity Date, reduces the interest rate applicable to the Revolving
Loans or the fees payable to the Revolving Lenders or extends the time for payment of such interest
or fees shall be effective without the consent of all the Revolving Lenders (in lieu of the consent
of the Majority Lenders); (iv) no amendment, modification or waiver which increases the Revolving
Commitment or the Term Commitment of any Lender shall be effective without the consent of such
Lender; and (v) no amendment, modification or waiver which modifies the rights, duties or
obligations of the Administrative Agent shall be effective without the consent of the
Administrative Agent.

     Section 12.03 Expenses, Indemnity; Damage Waiver.

     (a) The Borrower agrees:

     (i) whether or not the Transactions hereby contemplated are consummated, to pay all reasonable
expenses of the Administrative Agent in the administration (both before and after the execution
hereof and including advice of counsel as to the rights and duties of the Administrative Agent and
the Lenders with respect thereto) of, and in connection with the negotiation,

-71-

 

syndication,
investigation, preparation, execution and delivery of, recording or filing of, preservation of
rights under, enforcement of, and refinancing, renegotiation or restructuring of, the Loan
Documents and any amendment, waiver or consent, whether or not effective, relating thereto
(including, without limitation, travel, photocopy, mailing, courier, telephone and other similar
expenses of the Administrative Agent, ongoing Collateral monitoring and protection, Collateral
releases and workout matters, the cost of environmental audits, surveys and appraisals, the
reasonable fees and disbursements of counsel and other outside consultants for the Administrative
Agent and, in the case of enforcement, the reasonable fees and disbursements of counsel for the
Administrative Agent and any of the Lenders); and promptly reimburse the Administrative Agent for
all amounts expended, advanced or incurred by the Administrative Agent or the Lenders to satisfy
any obligation of the Borrower under this Agreement or any Security Instrument, including without
limitation, all costs and expenses of foreclosure;

     (ii) to indemnify the Administrative Agent and each Lender and each Lender
Affiliate and each of their officers, directors, employees, representatives, Administrative Agent,
attorneys, accountants, investment advisors, agents, trustees and experts (“Indemnified
Parties”) from, hold each of them harmless against and promptly upon demand pay or reimburse
each of them for, the Indemnity Matters which may be incurred by or asserted against or involve any
of them (whether or not any of them is designated a party thereto) as a result of, arising out of
or in any way related to (a) any actual or proposed use by the Borrower of the proceeds of any of
the Loans or Letters of Credit, (b) the execution, delivery and performance of the Loan Documents,
(c) the operations of the business of UCLP, the Borrower and its Subsidiaries, (d) the failure of
UCLP, the Borrower or any Subsidiary to comply with the terms of any Security Instrument or this
Agreement, or with any Governmental Requirement, (e) any inaccuracy of any representation or any
breach of any warranty of UCLP or the Borrower set forth in any of the Loan Documents, (f) the
issuance, execution and delivery or transfer of or payment or failure to pay under any Letter of
Credit, (g) the payment of a drawing under any Letter of Credit notwithstanding the non-compliance,
non-delivery or other improper presentation of the manually executed draft(s) and certification(s),
(h) any assertion that the Lenders were not entitled to receive the proceeds received pursuant to
the Security Instruments or (i) any other aspect of the Loan Documents, including, without
limitation, the reasonable fees and disbursements of counsel and all other expenses incurred in
connection with investigating, defending or preparing to defend any such action, suit, proceeding
(including any investigations, litigation or inquiries) or claim and including all Indemnity
Matters arising by reason of the ordinary negligence of any Indemnified Party, but excluding all
Indemnity Matters arising solely by reason of claims between the Lenders or any Lender and the
Administrative Agent or a Lender’s shareholders against the Administrative Agent or Lender or by
reason of the gross negligence or willful misconduct on the part of such Indemnified Party;
and

     (iii) to indemnify and hold harmless from time to time the Indemnified Parties
from and against any and all losses, claims, cost recovery actions,

-72-

 

administrative orders or
proceedings, damages and liabilities to which any such Person may become subject (a) under any
Environmental Law applicable to UCLP, the Borrower or any Subsidiary or any of their Properties,
including without limitation, the treatment or disposal of hazardous substances on any of their
Properties, (b) as a result of the breach or non-compliance by UCLP, the Borrower or any Subsidiary
with any Environmental Law applicable to UCLP, the Borrower or any Subsidiary, (c) due to past
ownership by UCLP, the Borrower or any Subsidiary of any of their Properties or past activity on
any of their Properties which, though lawful and fully permissible at the time, could result in
present liability, (d) the presence, use, release, storage, treatment or disposal of hazardous
substances on or at any of the Properties owned or operated by UCLP, the Borrower or any
Subsidiary, or (e) any other environmental, health or safety condition in connection with the Loan
 Documents; provided, however, no indemnity shall be afforded under this
Section 12.03(a)(iii) in respect of any Property for any occurrence arising from
the acts or omissions of any Indemnified Party after the date which UCLP, the Borrower or any
Subsidiary is divested of ownership of such Property (whether by foreclosure or deed in lieu of
foreclosure, as mortgagee-in-possession or otherwise).

     (b) To the extent that the Borrower fails to pay any amount required to be paid by it to any
Agent, any Joint Lead Arranger or the Issuing Bank under Section 12.03(a), but without affecting
such payment obligations of the Borrower, each Revolving Lender severally agrees to pay to such
Agent, Joint Lead Arranger or the Issuing Bank, as the case may be, such Revolving Lender’s
Applicable Percentage (determined as of the time that the applicable unreimbursed expense or
indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense
or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred
by or asserted against such Agent, Joint Lead Arranger or the Issuing Bank in its capacity as such.

     (c) No Indemnified Party may settle any claim to be indemnified without the consent of the
indemnitor, such consent not to be unreasonably withheld; provided, that the indemnitor may
not reasonably withhold consent to any settlement that an Indemnified Party proposes, if the
indemnitor does not have the financial ability to pay all its obligations outstanding and asserted
against the indemnitor at that time, including the maximum potential claims against the Indemnified
Party to be indemnified pursuant to this Section 12.03.

     (d) In the case of any indemnification hereunder, the Administrative Agent or Lender, as
appropriate shall give notice to the Borrower of any such claim or demand being made against the
Indemnified Party and the Borrower shall have the non-exclusive right to join in the defense
against any such claim or demand provided that if the Borrower provides a defense, the
Indemnified Party shall bear its own cost of defense unless there is a conflict between the
Borrower and such Indemnified Party.

     (e) The foregoing indemnities shall extend to the Indemnified Parties
notwithstanding the sole or concurrent negligence of every kind or character whatsoever, whether
active or passive, whether an affirmative act or an 

-73-

 

omission, including without limitation, all
types of negligent conduct identified in the restatement (second) of torts of one or more of the
Indemnified Parties or by reason of strict liability imposed without fault on any one or more of
the Indemnified Parties. To the extent that an Indemnified Party is found to have committed an act
of gross negligence or willful misconduct, this contractual obligation of indemnification shall
continue but shall only extend to the portion of the claim that is deemed to have occurred by
reason of events other than the gross negligence or willful misconduct of the Indemnified
Party.

     (f) The Borrower’s obligations under this Section 12.03 shall be its joint and several
obligations and shall survive any termination of this Agreement and the payment of the Notes and
shall continue thereafter in full force and effect.

     (g) The Borrower shall pay any amounts due under this Section 12.03 within thirty (30) days of
the receipt by the Borrower of notice of the amount due.

     Section 12.04 Successors and Assigns.

     (a) This Agreement shall be binding upon and inure to the benefit of the parties hereto and
their respective successors and permitted assigns.

     (b) Neither UCLP nor the Borrower may assign its rights or obligations hereunder or under the
Notes or any Letters of Credit without the prior consent of all of the Lenders and the
Administrative Agent.

     (c) Any Lender may assign to one or more assignees, all or a portion of its rights and
obligations under this Agreement pursuant to an Assignment and Assumption substantially in the form
of Exhibit E upon the written consent (which consent shall not be unreasonably withheld) of
(A) with respect to the Revolving Credit Facility only, the Administrative Agent, provided
that no such consent shall be required for an assignment to an assignee that is an Affiliate (as
defined in clause (a) of the definition of “Affiliate”) of such Revolving Lender, or
a Revolving Lender immediately prior to giving effect to such assignment, (B) with respect to the
Term Loan Credit Facility only, the Administrative Agent, provided that no such consent
shall be required for an assignment to an assignee that is an Affiliate (as defined in clause (a)
of the definition of “Affiliate”) of such Revolving Lender
or a Revolving Lender
immediately prior to giving effect to such assignment, (C) the Issuing Banks (with respect to the
Revolving Credit Facility only), (D) with respect to the Revolving Credit Facility only, the
Borrower, provided that no such consent shall be required for an assignment to an assignee
that is an Affiliate (as defined in clause (a) of the definition of “Affiliate”) of such Term Loan
Lender, a Related Fund or a Term Loan Lender immediately prior to giving effect to such assignment,
or if an Event of Default has occurred and is continuing, any other assignee and (E) with respect
to the Term Loan Credit Facility only, the Borrower, provided that no such consent shall be
required for an assignment to an assignee that is an Affiliate (as defined in clause (a) of the
definition of “Affiliate”) of such Term Loan Lender, a Related Fund or a Term Loan Lender
immediately prior to giving effect to such assignment; provided, however, that (i)
any such assignment shall be in the amount of at least $5,000,000 with respect to the Revolving
Credit Facility and at least $1,000,000 with respect to the Term Loan Facility or such lesser
amount to

-74-

 

which such Borrower has consented, with Related Funds treated as one assignee for
purposes of determining compliance with such minimum assignment amount; (ii) the assignee or
assignor shall pay to the Administrative Agent a processing and recordation fee of $3,500 for each
assignment; provided that only $3,500 shall be payable in connection with simultaneous
assignments to or by two or more Related Funds; (iii) any assignee shall not be a competitor of
UCLP or any of its Subsidiaries in any of the lines of business permitted under Section 9.05; and
(iv) notwithstanding anything to the contrary contained in this Agreement, if such assignment is
made at a time when an Event of Default has occurred and is continuing, the Borrower shall have the
right to withhold all Taxes required by law to be withheld from payments made hereunder, and shall
pay such Taxes to the relevant taxing authority or other Governmental Authority in accordance with
applicable law. Any such assignment will become effective upon the execution
and delivery to the Administrative Agent of the Assignment and Assumption and the consent, if
required above, of the Administrative Agent, the Issuing Banks and, unless an Event of Default has
occurred and is continuing, the Borrower. Promptly after receipt of an executed Assignment and
Assumption, the Administrative Agent shall send to the Borrower a copy of such executed Assignment
and Assumption. Upon receipt of such executed Assignment and Assumption, the Borrower, will, at
its own expense, execute and deliver new Notes to the assignor and/or assignee, as appropriate, in
accordance with their respective interests as they appear. Upon the effectiveness of any
assignment pursuant to this Section 12.04(c), the assignee will become a “Lender,” if not already a
“Lender,” for all purposes of this Agreement and the Security Instruments. The assignor shall be
relieved of its obligations hereunder to the extent of such assignment (and if the assigning Lender
no longer holds any rights or obligations under this Agreement, such assigning Lender shall cease
to be a “Lender” hereunder except that its rights under Sections 5.01, 5.02, 5.03 and 12.03 shall
not be affected). The Administrative Agent, acting as an agent of the Borrower, shall maintain at
one of its offices a copy of each Assignment and Assumption delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the principal amount of the Loans and LC
Exposure owing to, each Lender pursuant to the terms hereof from time to time (the
“Register”). No assignment shall be effective for purposes of this Agreement unless it has
been recorded in the Register.

     (d) Each Lender may transfer, grant or assign participations in all or any part of such
Lender’s interests hereunder pursuant to this Section 12.04(d) to any Person that satisfies the
requirements of Section 12.04(c)(iii), provided that: (i) such Lender shall remain a
“Lender” for all purposes of this Agreement and the transferee of such participation shall not
constitute a “Lender” hereunder; and (ii) no participant under any such participation shall have
rights to approve any amendment to or waiver of any of the Loan Documents; provided that
such participation agreement may provide that such Lender will not, without the consent of the
participant, agree to any amendment, modification or waiver described in clauses (i), (ii) or (iii)
of the proviso to Section 12.02(b) that affects such participant, and all amounts payable by the
Borrower hereunder shall be determined as if such Lender had not sold such participation,
provided that such participant shall be entitled to receive additional amounts under
ARTICLE V on the same basis as if it were a Lender and be indemnified under Section 12.03 as if it
were a Lender. In addition, each agreement creating any participation must include an agreement by
the participant to be bound by the provisions of Section 12.11.

     (e) The Lenders may furnish any information concerning the Borrower in the possession of the
Lenders from time to time to assignees and participants (including prospective

-75-

 

assignees and
participants); provided that, such Persons agree to be bound by the provisions of Section
12.11.

     (f) Notwithstanding anything in this Section 12.04 to the contrary, any Lender may at any time
pledge or assign a security interest in all or any portion of its rights under this Agreement to
secure obligations of such Lender, including, without limitation, any pledge or assignment to
secure obligations to a Federal Reserve Bank; provided that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder or substitute any
such pledgee or assignee for such Lender as a party hereto.

     (g) Notwithstanding any other provisions of this Section 12.04, no transfer or assignment of
the interests or obligations of any Lender or any grant of participations therein shall be
permitted if such transfer, assignment or grant would require the Borrower to file a registration
statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

     Section 12.05 Survival; Revival; Reinstatement.

          (a) All covenants, agreements, representations and warranties made by the Borrower herein and
in the certificates or other instruments delivered in connection with or pursuant to this Agreement
or any other Loan Document shall be considered to have been relied upon by the other parties hereto
and shall survive the execution and delivery of this Agreement and the making of any Loans and
issuance of any Letters of Credit, regardless of any investigation made by any such other party or
on its behalf and notwithstanding that the Administrative Agent, any other Agent, the Issuing Bank
or any Lender may have had notice or knowledge of any Default or incorrect representation or
warranty at the time any credit is extended hereunder, and shall continue in full force and effect
as long as the principal of or any accrued interest on any Loan or any fee or any other amount
payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and
so long as the Aggregate Commitments have not expired or terminated. The provisions of ARTICLE V,
ARTICLE XI and Section 12.03 shall survive and remain in full force and effect regardless of the
consummation of the Transactions contemplated hereby, the repayment of the Loans, the expiration or
termination of the Letters of Credit and the Aggregate Commitments or the termination of this
Agreement, any other Loan Document or any provision hereof or thereof.

          (b) To the extent that any payments on the Indebtedness or proceeds of any collateral are
subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be
repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law,
common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived
and continue as if such payment or proceeds had not been received and the Administrative Agent’s
and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and
each Loan Document shall continue in full force and effect. In such event, each Loan Document
shall be automatically reinstated and UCLP and the Borrower shall take such action as may be
reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

-76-

 

     Section 12.06 Counterparts; Integration; Effectiveness.

          (a) This Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of which when taken
together shall constitute one and the same instrument.

          (b) This Agreement, the other Loan Documents and any separate letter agreements
with respect to fees payable to the Administrative Agent embody the entire agreement and understanding among the parties relating to the subject
matter hereof and thereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof and thereof. This Agreement and the other Loan
Documents represent the final agreement among the parties hereto and thereto and may not be
contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties.
There are no unwritten oral agreements between the parties.

          (c) Except as provided in Section 6.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent shall have
received counterparts hereof which, when taken together, bear the signatures of each of the other
parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto
and their respective successors and assigns. Delivery of an executed counterpart of a signature
page of this Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

     Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such invalidity, illegality or unenforceability without affecting the validity, legality and
enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular
provision in a particular jurisdiction shall not invalidate such provision in any other
jurisdiction.

          Section 12.08 Right of Setoff. The Borrower agrees that, in addition to (and without limitation of) any right of set-off,
bankers’ lien or counterclaim a Lender may otherwise have, each Lender shall have the right and be
entitled (after consultation with the Administrative Agent), at its option, to offset balances held
by it or by any of its Affiliates for account of the Borrower at any of its offices, in dollars or
in any other currency, against any principal of or interest on any of such Lender’s Loans, or any
other amount payable to such Lender hereunder, which is not paid when due (including applicable
grace periods) (regardless of whether such balances are then due to the Borrower), in which case it
shall promptly notify the Borrower and the Administrative Agent thereof, provided that such
Lender’s failure to give such notice shall not affect the validity thereof. Notwithstanding
anything to the contrary contained in this Agreement, the Lenders hereby agree that they shall not
set off any funds in any lock boxes whatsoever in connection with this Agreement, except for such
lock boxes which may be established in connection with this Agreement.

     Section 12.09 Governing Law; Jurisdiction; Consent to Service of
Process.

     (a) This Agreement and the Notes shall be governed by, and construed in
accordance with, the laws of the State of Texas except to the extent that United States federal law
permits any Lender to charge interest at the rate allowed by the laws of the state where such Lender is located. Ch. 346 of the Texas
Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party
accounts) shall not apply to this Agreement or the Notes.

     (b) Any legal action or proceeding with respect to the Loan Documents shall be
brought in the courts of the State of Texas or of the United States of America for the Southern
District of Texas, and, by execution and delivery of this Agreement, each of UCLP and the Borrower
hereby accepts for itself and (to the extent permitted by law) in respect of its Property,
generally and unconditionally, the jurisdiction of the aforesaid courts. Each of UCLP and the
Borrower hereby irrevocably waives any objection, including, without limitation, any objection to
the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter
have to the bringing of any such action or proceeding in such respective jurisdictions. This
submission to jurisdiction is non-exclusive and does not preclude the Administrative Agent or any
Lender from obtaining jurisdiction over UCLP or the Borrower in any court otherwise having
jurisdiction.

     (c) Each of UCLP and the Borrower irrevocably consents to the service of process
of any of the aforementioned courts in any such action or proceeding by the mailing of copies
thereof by registered or certified mail, postage prepaid, to UCLP and the Borrower at its address
located on the signature page hereto or as updated from time to time, such service to become
effective thirty (30) days after such mailing. 

     (d) Nothing herein shall affect the right of the Administrative Agent or any
Lender or any holder of a Note to serve process in any other manner permitted by law or to commence
legal proceedings or otherwise proceed against UCLP or the Borrower in any other jurisdiction.

     (e) Each of UCLP, the Borrower and each Lender hereby (i) irrevocably and
unconditionally waive, to the fullest extent permitted by law, trial by jury in any legal action or
proceeding relating to this Agreement or any other Loan Document and for any counterclaim therein;
(ii) irrevocably waive, to the maximum extent not prohibited by law, any right it may have
to claim or recover in any such litigation any special, exemplary, punitive or consequential
damages, or damages other than, or in addition to, actual damages; (iii) certify that no
party hereto nor any representative of the Administrative Agent or counsel for any party hereto has
represented, expressly or otherwise, or implied that such party would not, in the event of
litigation, seek to enforce the foregoing waivers, and (iv) acknowledge that it has been
induced to enter into this 

-78-

 

Agreement, the other Loan Documents and the transactions contemplated
hereby and thereby by, among other things, the mutual waivers and certifications contained in this
Section 12.09.

     Section 12.10 Headings. Article and Section headings and the Table of Contents used herein are for convenience of
reference only, are not part of this Agreement and shall not affect the construction of, or be
taken into consideration in interpreting, this Agreement.

     Section 12.11 Confidentiality. For the purposes of this Section 12.11, “Confidential Information” means information
about UCLP or the Borrower furnished by UCLP or the Borrower or their Affiliates (collectively, the
“Disclosing Parties”) to the Administrative Agent or any of the Lenders, including, but not
limited to, any actual or pending agreement, business plans, budgets, projections, ecological data
and accounting records, financial statements, or other financial data of any kind, any title
documents, reports or other information relating to matters of title, any projects or plans,
whether actual or prospective, and any other documents or items embodying any such Confidential
Information; provided that such term does not include information that (a) was publicly
known or otherwise known prior to the time of such disclosure, (b) subsequently becomes publicly
known through no act or omission by the Administrative Agent or the Lenders or any Person acting on
behalf thereof, (c) otherwise becomes known to the Administrative Agent or Lenders other than
through disclosure by the Disclosing Parties or a party known to be subject to a confidentiality
agreement or (d) constitutes financial statements delivered to the Administrative Agent and the
Lenders under Section 8.01(a) that are otherwise publicly available. The Administrative Agent and
the Lenders will maintain the confidentiality of such Confidential Information delivered to (i)
such Person, provided that each such Person (a “Restricted Person”) may deliver or
disclose Confidential Information to such Restricted Person’s directors, officers, employees,
agents, attorneys investment advisors, trustees and Affiliates, who agree to hold confidential the
Confidential Information substantially in accordance with the terms of this Section 12.11, (ii)
such Restricted Person’s financial advisors and other professional advisors who agree to hold
confidential the Confidential Information substantially in accordance with the terms of this
Section 12.11, (iii) any other Lender, (iv) any pledgee referred to in Section 12.04, any potential
assignee or any assignee to which such Restricted Person sells or offers to sell its Note or any
part thereof or any participation potential participation therein (if such Person has agreed in
writing prior to its receipt of such Confidential Information to be bound by the provisions of this
Section 12.11), (v) any Person from which such Restricted Person offers to purchase any security of
the Borrower (if such Person has agreed in writing prior to its receipt of such Confidential
Information to be bound by the provisions of this Section 12.11), (vi) any Governmental Authority
having jurisdiction or any self-regulatory body claiming to have authority over such Restricted
Person, (vii) the National Association of Insurance Commissioners or any similar organization, or
any nationally recognized rating agency that requires access to information about such Restricted
Person’s investment portfolio, or (viii) any other Person to which such delivery or disclosure may
be necessary or appropriate (A) to effect compliance with any Governmental Requirement applicable
to such Restricted Person, (B) in response to any subpoena or other legal process, (C) in
connection with any litigation to which such Restricted Person is a party or (D) if an Event of
Default has occurred and is continuing, to the extent such Restricted Person may reasonably
determine such delivery and disclosure to be necessary or appropriate in the enforcement or for the
protection of its rights and remedies under the Notes and this Agreement. Each Lender, by

-79-

 

its acceptance of a Note or a participation agreement, will be deemed to have agreed to be bound by and
to be entitled to the benefits of this Section 12.11 as though it were a party to this Agreement.
On reasonable request by UCLP or
the Borrower in connection with the delivery to any Lender of information required to be delivered
to such Lender under this Agreement or requested by such Lender (other than a Lender that is a
party to this Agreement or its nominee), such Lender will enter into an agreement with UCLP or the
Borrower embodying the provisions of this Section 12.11. UCLP and the Borrower waive (on their own
behalf and on behalf of their Subsidiaries) any and all other rights they (or their Subsidiaries)
may have to confidentiality as against the Administrative Agent and the Lenders arising by or under
any contract, agreement, statute or law except as expressly stated in this Section 12.11.

     Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall 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 (including the laws of the United States of America and the
State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender
notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding
anything to the contrary in any of the Loan Documents or any agreement entered into in connection
with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration
which constitutes interest under law applicable to any Lender that is contracted for, taken,
reserved, charged or received by such Lender under any of the Loan Documents or agreements or
otherwise in connection with the Notes shall under no circumstances exceed the maximum amount
allowed by such applicable law, and any excess shall be canceled automatically and if theretofore
paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the
extent that the principal amount of the Indebtedness shall have been or would thereby be paid in
full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the
Notes is accelerated by reason of an election of the holder thereof resulting from any Event of
Default under this Agreement or otherwise, or in the event of any required or permitted prepayment,
then such consideration that constitutes interest under law applicable to any Lender may never
include more than the maximum amount allowed by such applicable law, and excess interest, if any,
provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of
the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such
Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of
the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the
Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention
of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be
amortized, prorated, allocated and spread throughout the stated term of the Loans evidenced by the
Notes until payment in full so that the rate or amount of interest on account of any Loans
hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and
from time to time (i) the amount of interest payable to any Lender on any date shall be computed at
the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (ii) in
respect of any subsequent interest computation period the amount of interest otherwise payable to
such Lender would be less than the amount of interest payable to such Lender computed at the
Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender
in respect of such subsequent interest computation period shall continue to be computed at the
Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such
Lender shall equal the total amount of interest which would have been

-80-

 

payable to such Lender if the total amount of interest had been computed without giving effect to
this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code is relevant for the
purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to
determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in
effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower’s obligations
hereunder.

     Section 12.13 Exculpation Provisions. Each of the parties hereto specifically agrees that it has a duty to read this Agreement and
the other Loan Documents and agrees that it is charged with notice and knowledge of the terms of
this Agreement and the other Loan Documents; that it has in fact read this Agreement and is fully
informed and has full notice and knowledge of the terms, conditions and effects of this Agreement;
that it has been represented by independent legal counsel of its choice throughout the negotiations
preceding its execution of this Agreement and the other Loan Documents; and has received the advice
of its attorney in entering into this Agreement and the other Loan Documents; and that it
recognizes that certain of the terms of this Agreement and the other Loan Documents result in one
party assuming the liability inherent in some aspects of the transaction and relieving the other
party of its responsibility for such liability. Each party hereto agrees and covenants that it
will not contest the validity or enforceability of any exculpatory provision of this Agreement and
the other Loan Documents on the basis that the party had no notice or knowledge of such provision
or that the provision is not “conspicuous.”

     Section 12.14 Collateral Matters; Hedging Agreements. Notwithstanding anything to the contrary contained herein, the terms and provisions of this
Agreement shall not apply to any Hedging Agreements, except to the extent necessary for all Hedging
Agreements with Lenders and/or their Lender Affiliate to be secured by the Security Instruments on
a pari passu basis with other Indebtedness and for the proceeds from the Security Instruments to be
applied as set forth in Section 10.02(c) hereof. No Lender or any Lender Affiliate shall have any
voting rights under any Loan Document as a result of the existence of obligations owed to it under
any such Hedging Agreements.

     Section 12.15 No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the
Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the
benefit of the Borrower, and no other Person (including, without limitation, any Subsidiary of the
Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights,
claims, remedies or privileges hereunder or under any other Loan Document against the
Administrative Agent, any other Agent, the Issuing Bank or any Lender for any reason whatsoever.
There are no third party beneficiaries.

     Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies UCLP and the Borrower that pursuant to the requirements of the USA
Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “USA Patriot
Act”), it is required to obtain, verify and record information that identifies UCLP and its
Subsidiaries, which information includes the

-81-

 

name and address of UCLP and such Subsidiaries and
other information that will allow such Lender to identify UCLP and such Subsidiaries in accordance
with the USA Patriot Act.

     Section 12.17 No General Partner’s Liability. The Lenders agree that no claim arising against either UCLP, the Borrower or any Restricted
Subsidiary under any Loan Document shall be asserted against the General Partner (in its individual
capacity) and no judgment, order or execution entered in any suit, action or proceeding, whether
legal or equitable, on this Agreement or any of the other Loan Documents shall be obtained or
enforced against the General Partner (in its individual capacity) or its assets for the purpose of
obtaining satisfaction and payment of the Indebtedness or any claims arising under this Agreement
or any other Loan Document, any right to proceed against the General Partner individually or its
respective assets being hereby expressly waived by the Lenders. Nothing in this Section 12.17,
however, shall be construed so as to prevent the Administrative Agent or any Lender from commencing
any action, suit or proceeding with respect to or causing legal papers to be served upon the
General Partner for the purpose of (i) obtaining jurisdiction over UCLP, the Borrower or any
Restricted Subsidiary or (ii) obtaining judgment, order or execution against the General Partner
arising out of any fraud or intentional misrepresentation by the General Partner in connection with
the Loan Documents or of recovery of moneys received by the General Partner in violation of the
terms of this Agreement.

          (a) Each of the Guarantors hereby jointly and severally, unconditionally and irrevocably,
guarantees to the Guaranteed Creditors and each of their respective permitted successors,
indorsees, transferees and assigns, the prompt and complete payment in cash and performance by the
Borrower when due (whether at the stated maturity, by acceleration or otherwise) of the Borrower
Obligations. This is a guarantee of payment and not collection and the liability of each Guarantor
is primary and not secondary.

          (b) Anything herein or in any other Guaranteed Document to the contrary notwithstanding, the
maximum liability of each Guarantor hereunder and under the other Guaranteed Documents shall in no
event exceed the amount which can be guaranteed by such Guarantor under applicable federal and
state laws relating to the insolvency of debtors (after giving effect to the right of contribution
established in Section 2.02).

          (c) Each Guarantor agrees that the Borrower Obligations may at any time and from time to time
exceed the amount of the liability of such Guarantor hereunder without impairing the guarantee
contained in this ARTICLE II or affecting the rights and remedies of any Guaranteed Creditor
hereunder.

          (d) Each Guarantor agrees that if the maturity of the Borrower Obligations is accelerated by

secured by cash collateral as permitted in Section 2.07(a)(iii) of the Credit Agreement) and all of
the Aggregate Commitments are terminated, notwithstanding that from time to time during the term of
the Credit Agreement, no Borrower Obligations may be outstanding.

Exhibit F-2
— 3

 

 

          (e) No payment made by any Guarantor, any other guarantor or any other Person or received or
collected by any Guaranteed Creditor from any Guarantor, any other guarantor 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 Borrower Obligations shall be deemed to
modify, reduce, release or otherwise affect the liability of any Guarantor hereunder which shall,
notwithstanding any such payment (other than any payment made by such Guarantor in respect of the
Borrower Obligations or any payment received or collected from such Guarantor in respect of the
Borrower Obligations), remain liable for the Borrower Obligations up to the maximum liability of
such Guarantor hereunder until the Borrower Obligations are paid in full in cash, no Letter of
Credit is outstanding (except for Letters of Credit secured by cash collateral as permitted in
Section 2.07(a)(iii) of the Credit Agreement) and all of the Aggregate Commitments are terminated.

     Section 2.02 Right of Contribution. Each Guarantor hereby agrees that to the extent
that a Guarantor shall have paid more than its proportionate share of any payment made hereunder,
such Guarantor shall be entitled to seek and receive contribution from and against any other
Guarantor hereunder which has not paid its proportionate share of such payment. Each Guarantor’s
right of contribution shall be subject to the terms and conditions of Section 2.03. The provisions
of this Section 2.02 shall in no respect limit the obligations and liabilities of any Guarantor to
the Guaranteed Creditors, and each Guarantor shall remain liable to the Guaranteed Creditors for
the full amount guaranteed by such Guarantor hereunder.

     Section 2.03 No Subrogation. Notwithstanding any payment made by any Guarantor
hereunder or any set-off or application of funds of any Guarantor by any Guaranteed Creditor, no
Guarantor shall be entitled to be subrogated to any of the rights of any Guaranteed Creditor
against the Borrower or any other Guarantor or any collateral security or guarantee or right of
offset held by any Guaranteed Creditor for the payment of the Borrower Obligations, nor shall any
Guarantor seek or be entitled to seek any indemnity, exoneration, participation, contribution or
reimbursement from the Borrower or any other Guarantor in respect of payments made by such
Guarantor hereunder, until all amounts owing to the Guaranteed Creditors on account of the Borrower
Obligations are irrevocably and indefeasibly paid in full in cash, no Letter of Credit is
outstanding (except for Letters of Credit secured by cash collateral as permitted in Section
2.07(a)(iii) of the Credit Agreement) and all of the Aggregate Commitments are terminated. If any
amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of
the Borrower Obligations shall not have been irrevocably and indefeasibly paid in full in cash, any
Letter of Credit is outstanding (except for Letters of Credit secured by cash collateral as
permitted in Section 2.07(a)(iii) of the Credit Agreement) or any of the Aggregate Commitments are
in effect, such amount shall be held by such Guarantor in trust for the Guaranteed Creditors, and
shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent in the
exact form received by such Guarantor (duly indorsed by such Guarantor to the Administrative Agent,
if required), to be applied against the Borrower Obligations, whether matured or unmatured, in
accordance with Section 10.02(c) of the Credit Agreement.

     Section 2.04 Amendments, Etc. with respect to the Borrower Obligations. Each
Guarantor shall remain obligated hereunder, and such Guarantor’s obligations hereunder shall not be
released, discharged or otherwise affected, notwithstanding that, without any reservation

Creditor may be rescinded by such Guaranteed Creditor or otherwise and any of the Borrower
Obligations continued; (b) the Borrower Obligations, the liability of any other Person 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, or any indulgence or forbearance in
respect thereof granted by, any Guaranteed Creditor; (c) any Guaranteed Document may be amended,
modified, supplemented or terminated, in whole or in part, as the Guaranteed Creditors may deem
advisable from time to time; (d) any collateral security, guarantee or right of offset at any time
held by any Guaranteed Creditor for the payment of the Borrower Obligations may be sold, exchanged,
waived, surrendered or released; (e) any additional guarantors, makers or endorsers of the Borrower
Obligations may from time to time be obligated on the Borrower Obligations or any additional
security or collateral for the payment and performance of the Borrower Obligations may from time to
time secure the Borrower Obligations; and (f) any other event shall occur which constitutes a
defense or release of sureties generally. No Guaranteed Creditor shall have any obligation to
protect, secure, perfect or insure any Lien at any time held by it as security for the Borrower
Obligations or for the guarantee contained in this ARTICLE II or any Property subject thereto.

     Section 2.05 Waivers. Each Guarantor hereby waives any and all notice of the
creation, renewal, extension or accrual of any of the Borrower Obligations and notice of or proof
of reliance by any Guaranteed Creditor upon the guarantee contained in this ARTICLE II or

notice of creation of the Borrower Obligations or any extension of credit already or hereafter
contracted by or extended to the Borrower needs to be given to any Guarantor; and all dealings

the other hand, likewise shall be conclusively presumed to have been had or consummated in reliance
upon the guarantee contained in this ARTICLE II. Each Guarantor waives diligence, presentment,
protest, demand for payment and notice of default or nonpayment to or upon the Borrower or any of
the Guarantors with respect to the Borrower Obligations.

     Section 2.06 Guaranty Absolute and Unconditional.

          (a) Each Guarantor understands and agrees that the guarantee contained in this ARTICLE II is,
and shall be construed as, a continuing, completed, absolute and unconditional guarantee of
payment, and each Guarantor hereby waives any defense of a surety or guarantor or any other obligor
on any obligations arising in connection with or in respect of any of the following and hereby
agrees that its obligations hereunder shall not be discharged or otherwise affected as a result of,
any of the following:

     (i) the invalidity or unenforceability of any Guaranteed Document, any of the Borrower
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 any Guaranteed Creditor;

Exhibit F-2

of them or interest therein) in or as a result of such proceeding;

     (iv) any sale, lease or transfer of any or all of the assets of the Borrower or any
other Guarantor, or any changes in the shareholders of the Borrower or the Guarantor;

recognized and agreed by each of the Guarantors that it is not entering into this Agreement
in reliance on, or in contemplation of the benefits of, the validity, enforceability,
collectability or value of any of the Collateral for the Obligations;

     (vii) the absence of any attempt to collect the Obligations or any part of them from

make a similar demand on or otherwise pursue or exhaust such rights and remedies as it may have

guarantee for the Borrower Obligations or any right of offset with respect thereto, and any failure
by any Guaranteed Creditor to make any such demand, to pursue such other rights or remedies or to
collect any payments from the Borrower, any other Guarantor or any other Person or to realize upon
any such collateral security or guarantee or to exercise any such right of offset, or any release

to be a reference to such Guarantor’s knowledge.

Exhibit F-2
— 7

 

 

     Section 3.02 Benefit to the Guarantor. Each Borrower is a member of an affiliated
group of companies that includes each Guarantor and each Borrower and the other Guarantors are
engaged in related businesses. Each Guarantor (other than UCLP) is a Restricted Subsidiary of UCLP

convenient to the conduct, promotion and attainment of the business of such Guarantor and each
Borrower.

     Section 3.03 Solvency. Each Guarantor (a) is not insolvent as of the date hereof and
will not be rendered insolvent as a result of this Agreement (after giving effect to Section 2.02),

collateral as permitted in Section 2.07(a)(iii) of the Credit Agreement) and all of the Aggregate
Commitments shall have terminated:

     Section 4.01 Covenants in Credit Agreement. In the case of each Guarantor, such
Guarantor shall take, or shall refrain from taking, as the case may be, each action that is
necessary to be taken or not taken, as the case may be, so that no Default is caused by the failure
to take such action or to refrain from taking such action by such Guarantor or any of its
Restricted Subsidiaries.

ARTICLE V

     Section 5.01 Authority of Administrative Agent. Each Guarantor acknowledges that the
rights and responsibilities of the Administrative Agent under this Agreement with respect to any

Agent of any option, voting right, request, judgment or other right or remedy provided for herein
or resulting or arising out of this Agreement shall, as between the Administrative Agent and the
Guaranteed Creditors, be governed by the Credit Agreement and by such other agreements with respect
thereto as may exist from time to time among them, but, as between the Administrative Agent and the
Guarantors, the Administrative Agent shall be conclusively presumed to be acting as agent for the
Guaranteed Creditors with full and valid authority so to act or refrain from acting, and no
Guarantor shall be under any obligation, or entitlement, to make any inquiry respecting such
authority.

ARTICLE VI

Subordination of Indebtedness

     Section 6.01 Subordination of All Guarantor Claims. As used herein, the term
“Guarantor Claims” shall mean all debts and obligations of the Borrower or any other
Guarantor to any other Guarantor, whether such debts and obligations now exist or are hereafter
incurred or arise, or whether the obligation of the debtor thereon be direct, contingent, primary,
secondary, several, joint and several, or otherwise, and irrespective of whether such debts or
obligations be evidenced by note, contract, open account, or otherwise, and irrespective of the
Person or Persons in whose favor such debts or obligations may, at their inception, have been, or
may hereafter be created, or the manner in which they have been or may hereafter be acquired by.
After and during the continuation of an Event of Default, no Guarantor shall receive or collect,
directly or indirectly, from any obligor in respect thereof any amount upon the Guarantor Claims.

     Section 6.02 Claims in Bankruptcy. In the event of receivership, bankruptcy,
reorganization, arrangement, debtor’s relief, or other insolvency proceedings involving any
Guarantor, the Administrative Agent on behalf of the Administrative Agent and the Guaranteed
Creditors shall have the right to prove their claim in any proceeding, so as to establish their
rights hereunder and receive directly from the receiver, trustee or other court custodian,
dividends and payments which would otherwise be payable upon Guarantor Claims. Each Guarantor
hereby assigns such dividends and payments to the Administrative Agent for the benefit of the
Administrative Agent and the Guaranteed Creditors for application against the Borrower Obligations
as provided under Section 10.02(b) of the Credit Agreement. Should any Agent or Guaranteed
Creditor receive, for application upon the Obligations, any such dividend or payment which is
otherwise payable to any Guarantor, and which, as between such Guarantors, shall constitute a
credit upon the Guarantor Claims, then upon payment in full in cash of the Borrower Obligations,
the expiration of all Letters of Credit (except for Letters of Credit secured by cash collateral as
permitted in Section 2.07(a)(iii) of the Credit Agreement) and the termination of all of the
Aggregate Commitments, the intended recipient shall become subrogated to the rights of the
Administrative Agent and the Guaranteed Creditors to the extent that such payments to the
Administrative Agent and the Lenders on the Guarantor Claims have contributed toward the
liquidation of the Obligations, and such subrogation shall be with respect to that proportion of
the Obligations which would have been unpaid if the Administrative Agent and the Guaranteed
Creditors had not received dividends or payments upon the Guarantor Claims.

     Section 6.03 Payments Held in Trust. In the event that notwithstanding Section 6.01
and Section 6.02, any Guarantor should receive any funds, payments, claims or distributions which
is prohibited by such Sections, then it agrees: (a) to hold in trust for the Administrative Agent
and the Guaranteed Creditors an amount equal to the amount of all funds, payments, claims or
distributions so received, and (b) that it shall have absolutely no dominion over the amount of
such funds, payments, claims or distributions except to pay them promptly to the Administrative
Agent, for the benefit of the Guaranteed Creditors; and each Guarantor covenants promptly to pay
the same to the Administrative Agent.

     Section 6.04 Liens Subordinate. Each Guarantor agrees that, until the Borrower
Obligations are paid in full in cash, the expiration of all Letters of Credit (except for Letters
of Credit secured by cash collateral as permitted in Section 2.07(a)(iii) of the Credit Agreement)

Exhibit F-2
— 9

 

 

and the termination of all of the Aggregate Commitments, any Liens securing payment of the
Guarantor Claims shall be and remain inferior and subordinate to any Liens securing payment of the
Obligations, regardless of whether such encumbrances in favor of such Guarantor, the Administrative
Agent or any Guaranteed Creditor presently exist or are hereafter created or attach. Without the
prior written consent of the Administrative Agent, no Guarantor, during the period in which any of
the Borrower Obligations are outstanding or the Aggregate Commitments are in effect, shall (a)
exercise or enforce any creditor’s right it may have against any debtor in respect of the Guarantor
Claims, or (b) foreclose, repossess, sequester or otherwise take steps or institute any action or
proceeding (judicial or otherwise, including without limitation the commencement of or joinder in
any liquidation, bankruptcy, rearrangement, debtor’s relief or insolvency proceeding) to enforce
any Lien held by it.

     Section 6.05 Notation of Records. Upon the request of the Administrative Agent, all
promissory notes and all accounts receivable ledgers or other evidence of the Guarantor Claims
accepted by or held by any Guarantor shall contain a specific written notice thereon that the
indebtedness evidenced thereby is subordinated under the terms of this Agreement.

ARTICLE VII

Miscellaneous

     Section 7.01 Waiver. No failure on the part of the Administrative Agent or any
Guaranteed Creditor to exercise and no delay in exercising, and no course of dealing with respect
to, any right, power, privilege or remedy or any abandonment or discontinuance of steps to enforce
such right, power, privilege or remedy under this Agreement or any other Loan Document shall
operate as a waiver thereof, nor shall any single or partial exercise of any right, power,
privilege or remedy under this Agreement or any other Loan Document preclude or be construed as a
waiver of any other or further exercise thereof or the exercise of any other right, power,
privilege or remedy. The remedies provided herein are cumulative and not exclusive of any remedies
provided by law or equity.

     Section 7.02 Notices. All notices and other communications provided for herein shall
be given in the manner and subject to the terms of Section 12.01 of the Credit Agreement; provided
that any such notice, request or demand to or upon any Guarantor shall be addressed to such
Guarantor at its notice address set forth on Schedule 1.

     Section 7.03 Amendments in Writing. None of the terms or provisions of this Agreement
may be waived, amended, supplemented or otherwise modified except in accordance with Section 12.02
of the Credit Agreement.

     Section 7.04 Successors and Assigns. The provisions of this Agreement shall be
binding upon the Guarantors and their successors and assigns and shall inure to the benefit of the
Administrative Agent and the Guaranteed Creditors and their respective successors and assigns;
provided that except as set forth in Section 12.04 of the Credit Agreement, no Guarantor may
assign, transfer or delegate any of its rights or obligations under this Agreement without the
prior written consent of the Administrative Agent and the Lenders, and any such purported
assignment, transfer or delegation shall be null and void.

Exhibit F-2
— 10

 

 

     Section 7.05 Survival; Revival; Reinstatement.

          (a) All covenants, agreements, representations and warranties made by any Guarantor herein and
in the certificates or other instruments delivered in connection with or pursuant to this Agreement
or any other Loan Document to which it is a party shall be considered to have been relied upon by
the Administrative Agent, the other Agents, the Issuing Bank and the Lenders and shall survive the
execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of
Credit, regardless of any investigation made by any such other party or on its behalf and
notwithstanding that the Administrative Agent, the other Agents, the Issuing Bank or any Lender may
have had notice or knowledge of any Default or incorrect representation or warranty at the time any
credit is extended hereunder, and shall continue in full force and effect as long as the principal
of or any accrued interest on any Loan or any fee or any other amount payable under the Credit
Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the
Aggregate Commitments have not expired or terminated.

          (b) To the extent that any payments on the Guarantor Obligations are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor
in possession, receiver or other Person under any bankruptcy law, common law or equitable cause,
then to such extent, the Guarantor Obligations so satisfied shall be revived and continue as if
such payment or proceeds had not been received and the Administrative Agent’s and the Guaranteed
Creditors’ Liens, security interests, rights, powers and remedies under this Agreement and each
other Loan Document shall continue in full force and effect. In such event, each Loan Document
shall be automatically reinstated and the Borrower shall take such action as may be reasonably
requested by the Administrative Agent and the Guaranteed Creditors to effect such reinstatement.

     Section 7.06 Counterparts; Integration; Effectiveness.

          (a) This Agreement may be executed in counterparts (and by different parties hereto on
different counterparts), each of which shall constitute an original, but all of which when taken
together shall constitute a single contract.

          (b) This Agreement and the other Loan Documents embody the entire agreement and understanding
between the parties and supersede all other agreements and understandings between such parties
relating to the subject matter hereof and thereof. This Agreement and the Loan Documents represent
the final agreement between the parties and may not be contradicted by evidence of prior,
contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral
agreements between the parties.

          (c) This Agreement shall become effective when it shall have been executed by the
Administrative Agent and when the Administrative Agent shall have received counterparts hereof
which, when taken together, bear the signatures of each of the other parties hereto, and thereafter
shall be binding upon and inure to the benefit of the parties hereto, the Lenders and their
respective successors and assigns. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this
Agreement.

Exhibit F-2
— 11

 

 

     Section 7.07 Severability. Any provision of this Agreement or any other Loan Document
held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such invalidity, illegality or unenforceability without affecting the
validity, legality and enforceability of the remaining provisions hereof or thereof; and the
invalidity of a particular provision in a particular jurisdiction shall not invalidate such
provision in any other jurisdiction.

     Section 7.08 Set-Off. If an Event of Default shall have occurred and be continuing,
each Lender and each of its Affiliates 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 obligations (of whatsoever kind,
including, without limitations obligations under Hedging Agreements) at any time owing by such
Lender or Affiliate to or for the credit or the account of any Guarantor against any of and all the
obligations of the Guarantor owed to such Lender now or hereafter existing under this Agreement or
any other Loan Document, irrespective of whether or not such Lender shall have made any demand
under this Agreement or any other Loan Document and although such obligations may be unmatured.
The rights of each Lender under this Section 7.08 are in addition to other rights and remedies
(including other rights of setoff) which such Lender or its Affiliates may have. Notwithstanding
anything to the contrary contained in this Agreement, the Lenders hereby agree that they shall not
set off any funds in any lock boxes whatsoever in connection with this Agreement, except for such
lock boxes which may be established in connection with this Agreement.

     Section 7.09 Governing Law; Submission to Jurisdiction.

          (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF TEXAS.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
SHALL BE BROUGHT IN THE COURTS OF THE STATE OF TEXAS OR OF THE UNITED STATES OF AMERICA FOR THE
SOUTHERN DISTRICT OF TEXAS, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE PARTIES
HEREBY ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY,

VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO
JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER
ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

          (c) EACH GUARANTOR IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED
COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED
MAIL, POSTAGE PREPAID, TO SUCH GUARANTOR AT ITS ADDRESS

SET FORTH ON SCHEDULE 1 HERETO OR AS UPDATED FROM TIME TO TIME, SUCH SERVICE TO BECOME
EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING.

          (d) NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE ADMINISTRATIVE AGENT OR ANY LENDER OR ANY
HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL
PROCEEDINGS OR OTHERWISE PROCEED AGAINST THE GUARANTOR IN ANY OTHER JURISDICTION.

          (e) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY
SECURITY INSTRUMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM
EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY

ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OF THE ADMINISTRATIVE
AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH
PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv)
ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE SECURITY INSTRUMENTS AND
THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND

     Section 7.10 Headings. Article and Section headings and the Table of Contents used
herein are for convenience of reference only, are not part of this Agreement and shall not affect
the construction of, or be taken into consideration in interpreting, this Agreement.

     Section 7.11 Acknowledgments. Each Guarantor hereby acknowledges that:

          (a) it has been advised by counsel in the negotiation, execution and delivery of this
Agreement and the other Loan Documents to which it is a party;

          (b) neither the Administrative Agent nor any Guaranteed Creditor has any fiduciary
relationship with or duty to any Guarantor arising out of or in connection with this Agreement or
any of the other Loan Documents, and the relationship between the Guarantors, on the one hand, and
the Administrative Agent and Guaranteed Creditors, on the other hand, in connection herewith or
therewith is solely that of debtor and creditor; and

          (c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by
virtue of the transactions contemplated hereby among the Guaranteed Creditors or among the
Guarantors and the Guaranteed Creditors.

          (d) Each of the parties hereto specifically agrees that it has a duty to read this Agreement,
the Security Instruments and the other Loan Documents and agrees that it is charged with notice and
knowledge of the terms of this Agreement, the Security Instruments and the

Exhibit F-2
— 13

 

 

other Loan Documents; that it has in fact read this Agreement, the Security Instruments and
the other Loan Documents and is fully informed and has full notice and knowledge of the terms,
conditions and effects thereof; that it has been represented by independent legal counsel of its
choice throughout the negotiations preceding its execution of this Agreement and the Security
Instruments; and has received the advice of its attorney in entering into this Agreement and the
Security Instruments; and that it recognizes that certain of the terms of this Agreement and the
Security Instruments result in one party assuming the liability inherent in some aspects of the
transaction and relieving the other party of its responsibility for such liability. EACH PARTY
HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY
EXCULPATORY PROVISION OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS ON THE BASIS THAT THE PARTY
HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

     Section 7.12 Additional Guarantors. Each Significant Domestic Subsidiary of UCLP that
is required to become a party to this Agreement pursuant to Section 8.07 of the Credit Agreement
shall become an Guarantor for all purposes of this Agreement upon execution and delivery by such
Subsidiary of an Assumption Agreement in the form of Annex I hereto and shall thereafter
have the same rights, benefits and obligations as an Guarantor party hereto on the date hereof.

     Section 7.13 Acceptance. Each Guarantor hereby expressly waives notice of acceptance
of this Agreement, acceptance on the part of the Administrative Agent and the Guaranteed Creditors
being conclusively presumed by their request for this Agreement and delivery of the same to the
Administrative Agent

     Section 7.14 No General Partner’s Liability. The Lenders agree that no claim arising
against either the Borrower, UCLP or any Guarantor under this Agreement shall be asserted against
the General Partner (in its individual capacity) and no judgment, order or execution entered in any
suit, action or proceeding, whether legal or equitable, on this Agreement or any of the other Loan
Documents shall be obtained or enforced against the General Partner (in its individual capacity) or
its assets for the purpose of obtaining satisfaction and payment of the Indebtedness or any claims
arising under this Agreement or any other Loan Document, any right to proceed against the General
Partner individually or its respective assets being hereby expressly waived by the Lenders.
Nothing in this Section 7.14, however, shall be construed so as to prevent the Administrative Agent
or any Lender from commencing any action, suit or proceeding with respect to or causing legal
papers to be served upon the General Partner for the purpose of (i) obtaining jurisdiction over the
Borrower, UCLP or any other Guarantor or (ii) obtaining judgment, order or execution against the
General Partner arising out of any fraud or intentional misrepresentation by the General Partner in
connection with the Loan Documents or of recovery of moneys received by the General Partner in
violation of the terms of this Agreement.
