extent caused by Bank's gross negligence or willful misconduct.

          (c)     Borrower may request that Bank issue a Letter of Credit

Advance to Borrower of the equivalent of the amount thereof (plus cable charges)
in United States currency at the then prevailing rate of exchange in San
Francisco, California, for sales of that other currency for cable transfer to
the country of which it is the currency.

          (d)     Upon the issuance of any letter of credit payable in a
currency other than United States Dollars, Bank shall create a reserve (the
"Letter of Credit Reserve") under the Revolving Line for letters of credit
against fluctuations in currency exchange rates, in an amount equal to ten
percent (10%) of the face amount of such letter of credit. The amount of such
reserve may be amended by Bank from time to time to account fro fluctuations in
the exchange rate. The availability of funds under the Revolving Line shall be
reduced by the amount of such reserve for so long as such letter of credit
remains outstanding.

          2.1.3   FOREIGN EXCHANGE SUBLIMIT. If there is availability under the
Revolving Line and the Borrowing Base, then Borrower may enter in foreign
exchange forward contracts with the Bank under which Borrower commits to
purchase from or sell to Bank a set amount of foreign currency more than one
business day after the contract date (the "FX Forward Contract"). Bank shall
subtract 10% of each outstanding FX Forward Contract from the foreign exchange
sublimit, which sublimit is a maximum of $6,500,000.00 (the "FX Reserve"). The
total FX Forward Contracts at any one time may not exceed 10 times the amount of
the FX Reserve. Bank may terminate the FX Forward Contracts if an Event of
Default occurs.

          2.1.4   CASH MANAGEMENT SERVICES SUBLIMIT. Borrower may use up to
$6,500,000.00 for the Bank's Cash Management Services, which may include
merchant services, direct deposit of payroll, business credit card, and check
cashing services identified in the various cash management services agreements
related to such Cash Management Services (the "Cash Management Services"). Such
aggregate amounts utilized under the Cash Management Services Sublimit shall at
all times reduce the amount otherwise available for Credit Extensions under the
Revolving Line. Any amounts Bank pays on behalf of Borrower or any amounts that
are not paid by Borrower for any Cash Management Services will be treated as
Advances under the Revolving Line and will accrue interest at the interest rate
applicable to Advances.

     2.2  OVERADVANCES. If Borrower's Obligations under Section 2.1.1, 2.1.2,
2.1.3 and 2.1.4 exceed the lesser of either (i) the Revolving Line or (ii) the
Borrowing Base, Borrower must immediately pay in cash to Bank the excess.

     2.3  INTEREST RATE; PAYMENTS.

          (a)     INTEREST RATE. The principal amounts outstanding under the
Revolving Line shall accrue interest at a per annum rate equal to the aggregate
of the Prime Rate PLUS one percent (1.0%). After an Event of Default,
Obligations shall bear interest at three percent (3.0%) above the rate effective
immediately before the Event of Default. The applicable interest rate hereunder
shall increase or decrease when the Prime Rate changes. Interest is computed on
the basis of a 360 day year for the actual number of days elapsed.

          (b)     PAYMENTS. Interest is payable on the first of each month.
Payments received after 3:00 p.m. Eastern time are considered received at the
opening of business on the next Business Day. When a payment is due on

                                       -2-
<Page>

a day that is not a Business Day, the payment is due the next Business Day and
additional fees or interest, as applicable, shall continue to accrue.

          (c)     DEBIT OF ACCOUNTS. Bank may debit any of Borrower's deposit
accounts including Account Number _______________ for principal and interest
payments or any amounts Borrower owes Bank. Bank shall promptly notify Borrower
when it debits Borrower's accounts. These debits are not a set-off.

          (d)     REVOLVING LINE CLEAN-UP. Without notice or demand by Bank,
Borrower shall repay all Advances (not to include the face amount of any issued
but undrawn Letters of Credit) maintaining a zero dollar ($0.00) balance for a
period of forty-five (45) consecutive days during each calendar quarter during
the term hereof, and not request additional Advances during such forty-five (45)
day period.

     2.4  FEES. Borrower shall pay to Bank:

          (a)     FACILITY FEE. A fully earned, non-refundable facility fee of
     $38,000.00 due on the Closing Date; and

          (b)     LETTER OF CREDIT FEE. The Borrower shall pay the Bank's
     customary fees and expenses for the issuance of Letter of Credit,
     including, without limitation, a Letter of Credit Fee of one percent (1.0%)
     per annum of the face amount of each Letter of Credit issued, upon the
     issuance or renewal of such Letter of Credit by the Bank;

          (c)     UNUSED LINE FEE. In the event, in any calendar quarter, the
     average daily principal balance of the Revolving Line (including the face
     amount of issued but undrawn Letter of Credit) outstanding during the
     quarter is less than $15,000,000.00, Borrower shall pay Bank an unused line
     fee in an amount equal to 0.25% per annum on the difference between
     $15,000,000.00 and the average daily principal balance of the Revolving
     Credit (including the face amount of issued but undrawn Letters of Credit)
     outstanding during the quarter, which unused line fee shall be computed and
     paid quarterly, in arrears, on the first day of the following quarter.

4    CREATION OF SECURITY INTEREST

     4.1  GRANT OF SECURITY INTEREST. Borrower hereby grants Bank, to secure the
payment and performance in full of all of the Obligations and the performance of
each of Borrower's duties under the Loan Documents, a continuing security
interest in, and pledges and assigns to the Bank, the Collateral, wherever
located, whether now owned or hereafter acquired or arising, and all proceeds
and products thereof. Borrower warrants and represents that the security
interest granted herein shall be a first priority security interest in the
Collateral.

Except as noted on the Schedule, Borrower is not a party to, nor is bound by,
any material license or other agreement with respect to which the Borrower is
the licensee that prohibits or otherwise restricts Borrower from granting a
security interest in Borrower's interest in such license or agreement or any
other property. Without prior consent from Bank, Borrower shall not enter into,
or become bound by, any such license or agreement which is reasonably likely to
have a material impact on Borrower's business or financial condition. Borrower
shall take such steps as Bank requests to obtain the consent of, or waiver by,
any person whose consent or waiver is necessary for all such licenses or
contract rights to be deemed "Collateral" and for Bank to have a security
interest in it that might otherwise be restricted or prohibited by law or by the
terms of any such license or agreement, whether now existing or entered into in
the future.

If the Agreement is terminated, Bank's lien and security interest in the
Collateral shall continue until Borrower fully satisfies its Obligations. If
Borrower shall at any time, acquire a commercial tort claim, Borrower shall
promptly notify Bank in a writing signed by Borrower of the brief details
thereof and grant to Bank in such writing a security interest therein and in the
proceeds thereof, all upon the terms of this Agreement, with such writing to be
in form and substance satisfactory to Bank.

     4.2  AUTHORIZATION TO FILE FINANCING STATEMENTS. Borrower hereby authorizes
Bank to file financing statements, without notice to Borrower, with all
appropriate jurisdictions in order to perfect or protect Bank's interest or
rights hereunder, which financing statements may indicate the Collateral as
"all assets of the Debtor" or words of similar effect, or as being of an equal
or lesser scope, or with greater detail, all in Bank's discretion.

5    REPRESENTATIONS AND WARRANTIES

     Borrower represents and warrants as follows:

     5.1  DUE ORGANIZATION AND AUTHORIZATION. Borrower and each Subsidiary is
duly existing and in good standing in its state of formation and qualified and
licensed to do business in, and in good standing in, any state in which the
conduct of its business or its ownership of property requires that it be
qualified except where the failure to do so could not reasonably be expected to
cause a Material Adverse Change. The Borrower represents and warrants to the
Bank that: (a) the Borrower's exact legal name is that indicated on the
Perfection Certificate and on the signature page hereof; and (b) the Borrower is
an organization of the type, and is organized in the jurisdiction, set forth in
the Perfection Certificate; and (c) the Perfection Certificate accurately sets
forth the Borrower's organizational identification number

                                       -4-
<Page>

or accurately states that the Borrower has none; and (d) the Perfection
Certificate accurately sets forth the Borrower's place of business, or, if more
than one, its chief executive office as well as the Borrower's mailing address
if different, and (e) all other information set forth on the Perfection
Certificate pertaining to the Borrower is accurate and complete. If the Borrower
does not now have an organizational identification number, but later obtains
one, Borrower shall forthwith notify the Bank of such organizational
identification number.

     The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's organizational documents,
nor constitute an event of default under any material agreement by which
Borrower is bound. Borrower is not in default under any agreement to which or by
which it is bound in which the default could reasonably be expected to cause a
Material Adverse Change.

     5.2  COLLATERAL. Borrower has good title to the Collateral, free of Liens
except Permitted Liens. Borrower has no deposit account, other than the deposit
accounts with Bank and deposit accounts described in the Perfection Certificate
delivered to the Bank in connection herwith. The Accounts are bona fide,
existing obligations, and the service or property has been performed or
delivered to the account debtor or its agent for immediate shipment to and
unconditional acceptance by the account debtor. The Collateral is not in the
possession of any third party bailee (such as a warehouse). Except as hereafter
disclosed to the Bank in writing by Borrower, none of the components of the
Collateral shall be maintained at locations other than as provided in the
Perfection Certificate. In the event that Borrower, after the date hereof,
intends to store or otherwise deliver any portion of the Collateral to a bailee,
then Borrower will first receive the written consent of Bank and such bailee
must acknowledge in writing that the bailee is holding such Collateral for the
benefit of Bank. Borrower has no knowledge of any actual or imminent Insolvency
Proceeding of any account debtor whose accounts are an Eligible Account in any
Borrowing Base Certificate. All Inventory is in all material respects of good
and marketable quality, free from material defects. Borrower is the sole owner
of the Intellectual Property, except for non-exclusive licenses granted to its
customers in the ordinary course of business. Each Patent is valid and
enforceable and no part of the Intellectual Property has been judged invalid or
unenforceable, in whole or in part, and no claim has been made that any part of
the Intellectual Property violates the rights of any third party except to the
extent such claim could not reasonably be expected to cause a Material Adverse
Change.

     5.3  LITIGATION. Except as shown in the Schedule, there are no actions or
proceedings pending or, to the knowledge of Borrower's Responsible Officers or
legal counsel, threatened by or against Borrower or any Subsidiary in which an
adverse decision could reasonably be expected to cause a Material Adverse
Change.

     5.4  NO MATERIAL DEVIATION IN FINANCIAL STATEMENTS. All consolidated
financial statements for Borrower and any Subsidiary delivered to Bank fairly
present in all material respects Borrower's consolidated financial condition and
Borrower's consolidated results of operations. There has not been any material
deterioration in Borrower's consolidated financial condition since the date of
the most recent financial statements submitted to Bank.

     5.5  SOLVENCY. Borrower is able to pay its debts (including trade debts) as
they mature.

     5.6  REGULATORY COMPLIANCE. Borrower is not an "investment company" or a
company "controlled" by an "investment company" under the Investment Company
Act. Borrower is not engaged as one of its important activities in extending
credit for margin stock (under Regulations T and U of the Federal Reserve Board
of Governors). To Borrower's knowledge, Borrwer has complied in all material
respects with the Federal Fair Labor Standards Act. To Borrower's knowledge,
Borrower has not violated any laws, ordinances or rules, the violation of which
could reasonably be expected to cause a Material Adverse Change. None of
Borrower's or any Subsidiary's properties or assets has been used by Borrower or
any Subsidiary or, to the best of Borrower's knowledge, by previous Persons, in
disposing, producing, storing, treating, or transporting any hazardous substance
other than legally. Borrower and each Subsidiary has timely filed all required
tax returns and paid, or made adequate provision to pay, all material taxes,
except those being contested in good faith with adequate reserves under GAAP.
Borrower and each Subsidiary has obtained all consents, approvals and
authorizations of, made all declarations or filings with, and given all notices
to, all government authorities that are necessary to continue its business as
currently conducted except where the failure to make such declarations, notices
or filings would not reasonably be expected to cause a Material Advserse Change.

other equity securities except for Permitted Investments.

     5.8  FULL DISCLOSURE. No written representation, warranty or other
statement of Borrower in any certificate or written statement given to Bank
taken together with all such written certificates and written statements given
to Bank contains any untrue statement of a material fact or omits to state a
material fact necessary to make the statements contained in the certificates or
statements not misleading (it being recognized by Bank that the projections and
forecasts provided by Borrower in good faith and based upon reasonable

periods covered by such projections and forecasts may differ from the projected

Engage in or permit any of its Subsidiaries to engage in any business other than
the businesses currently engaged in by Borrower or reasonably related thereto,
or have a material change in its ownership or management. Borrower shall not,
without at least fifteen(15) days prior written notice to Bank: (i) relocate its

its jurisdiction or organization, or (iii) change its organizational structure
or type, or (iv) change its legal name, or (v) change any organizational number
(if any) assigned by its jurisdiction of organization.

     7.3  MERGERS OR ACQUISITIONS. Merge or consolidate, or permit any of its
Subsidiaries to merge or consolidate, with any other Person, or acquire, or

capital stock or property of another Person; provided, however, Subsidiaries may
merge together or into Borrower.

     7.4  INDEBTEDNESS. Create, incur, assume, or be liable for any
Indebtedness, or permit any Subsidiary to do so, other than Permitted

any Person, or make any Investment in any Person, other than Permitted
Investments, or permit any of its Subsidiaries to do so; or (ii) pay any
dividends or make any distribution or payment or redeem, retire or purchase any
capital stock.

     7.7  TRANSACTIONS WITH AFFILIATES. Directly or indirectly enter into or
permit to exist any material transaction with any Affiliate of Borrower, except
for transactions that are in the ordinary course of Borrower's business,

                                       -8-
<Page>

upon fair and reasonable terms that are no less favorable to Borrower than would
be obtained in an arm's length transaction with a non-affiliated Person.

     7.8  SUBORDINATED DEBT. Make or permit any payment on any Subordinated
Debt, except pursuant to the terms of the Subordinated Debt, or amend any
material provision in any document relating to the Subordinated Debt, without
Bank's prior written consent. Borrower and Bank hereby acknowledge and agree
that the Obligations are and shall at all times constitute "Designated Senior
Indebtedness" of Borrower with respect to each of its subordinated creditors,
including, without limitation, those subordinated creditors party to a certain
Indenture dated March 15, 2000 (the "Indenture"). Borrower hereby represents,
warrants and certifies that it has, on or about November 25, 2002, delivered to
the Trustee under the Indenture a notice in accordance with the terms of the
Indenture to confirm that the Obligations constitute Designated Senior
Indebtedness. Borrower hereby agrees that it will not materially modify any of
the terms and conditions of the Indenture without Bank's prior written consent
in each instance. Borrower shall not make any payments of any kind (including,
without limitation, pursuant to Section 13.1 of the Indenture) to, or for the
benefit of, any of the subordinated debt holders or the Trustee under the
Indenture without Bank's prior written consent in each instance; provided,
however, prior to the occurrence of an Event of Default, Borrower may make
regularly scheduled payments of interest in accordance with the terms of the
Indenture. Notwithstanding the foregoing or the terms of such Subordinated Debt,
Borrower shall be permitted to prepay principal amounts outstanding under
Subordinated Debt solely with the cash proceeds raised from the issuance of
equity in Borrower after the date hereof, provided that at the time of such
payment there is no Event of Default then existing or an event existing that
with the giving of notice or the lapse of time, or both, will be an Event of
Default, or no Event of Default would exist immediately after the making of such
payment.

     7.9  COMPLIANCE. Become an "investment company" or a company, controlled by
an "investment company", under the Investment Company Act of 1940 or undertake
as one of its important activities extending credit to purchase or carry margin
stock, or use the proceeds of any Credit Extension for that purpose; fail to
meet the minimum funding requirements of ERISA, permit a Reportable Event or
Prohibited Transaction, as defined in ERISA, to occur; fail to comply with the
Federal Fair Labor Standards Act or violate any other law or regulation, if the
violation could reasonably be expected to have a material adverse effect on
Borrower's business or operations or would reasonably be expected to cause a
Material Adverse Change, or permit any of its Subsidiaries to do so.

8.   EVENTS OF DEFAULT

     Any one of the following is an Event of Default:

     8.1  PAYMENT DEFAULT. Borrower fails to pay any of the Obligations within
three (3) days after their due date. During such three (3) day period the
failure to cure the default shall not constitute an Event of Default (but no
Credit Extension shall be made during such period);

     8.2  COVENANT DEFAULT. Borrower fails or neglects to perform any obligation
in Section 6 or violates any covenant in Section 7 or fails or neglects to
perform, keep, or observe any other material term, provision, condition,

present or future agreement between Borrower and Bank and so to any default
under such other material term, provision, condition, covenant or agreement that
can be cured, has failed to cure the default within ten (10) days after the
occurrence thereof; provided, however, that if the default cannot by its nature
be cured within the ten (10) day period or cannot after diligent attempts by
Borrower be cured within such ten (10) day period, and such default is likely to
be cured within a reasonable time, then Borrower shall have an additional period
(which shall not in any case exceed thirty (30) days) to attempt to cure such
default, and within such reasonable time period the failure to cure the default
shall not be deemed an Event of Default (but no Credit Extensions shall be made
during such cure period). Grace periods provided under this section shall not
apply, among other things, to financial covenants or any other covenants that
are required to be satisfied, completed or tested by a date certain.

     8.3  MATERIAL ADVERSE CHANGE.  A Material Adverse Change occurs;

                                       -9-
<Page>

     8.4  ATTACHMENT. (i) Any material portion of Borrower's assets is attached,
seized, levied on, or comes into possession of a trustee or receiver and the

process upon the Borrower seeking to attach, by trustee or similar process, any
funds of the Borrower on deposit with the Bank, or any entity under control of
Bank (including a subsidiary); (iii) Borrower is enjoined, restrained, or
prevented by court order from conducting a material part of its business; (iv) a

assets; or (v) a notice of lein, levy, or assessment is filed against any of
Borrower's assets by any government agency and not paid within ten (10) days
after Borrower receives notice. These are not Events of Default if stayed or if
a bond is posted pending contest by Borrower (but no Credit Extentions shall be
made during the cure period);

     8.5  INSOLVENCY. (i) Borrower becomes insolvent; (ii) Borrower begins an
Insolvency Proceeding; or (iii) an Insolvency Proceeding is begun against
Borrower and not dismissed or stayed within thirty (30) days (but no Credit
Extensions shall be made before any Insolvency proceeding is dismissed);

     8.6  OTHER AGREEMENTS. If there is a default in any agreement to which
Borrower is a party with a third party or parties resulting in a right by such
third party or parties, whether or not exercised, to accelerate the maturity of
any Indedtness in an amount in excess of $250,000.00 or that could result in a
material Adverse Change;

     8.7  JUDGEMENTS. If a judgment or judgments for the payment of money in an
amount, individually or in the aggregate, of at least Two Hundred Thousand
Dollars ($200,000) shall be rendered against Borrower and shall remain

Extensions will be made prior to the satisfaction or stay of such judgment);

     8.8  MISREPRESENTATIONS. If Borrower or any Person acting for Borrower

any reason to be full force; or (ii) any Guarantor does not perform any
obligation under any guaranty of the Obligations; or (iii) any material
misrepresentation or material misstatement exists now or later in any warranty
or representation in any guaranty of the Obligations or in any certificate
delivered to Bank in connection with the guaranty; or (iv) any circumstance
described in section 7, or Sections 8.4, 8.5 or 8.7 occurs to any Guarantor, or
(v) the liquidation, winding up, termination of existence, or insolvency of any
Guarantor.

9    BANK'S RIGHTS AND REMEDIES

     9.1  RIGHTS AND REMEDIES. When an Event of Default occurs and continues
Bank may, without notice or demand, do any or all of the following:

          (a)     Declare all Obligations immediately due and payable (but if an
Event of default described in Section 8.5 occurs all Obligations are immediately
due and payable without any action by Bank);

          (b)     Stop advancing money or extending credit for Borrower's
benefit under this Agreement or under any other agreement between Borrower and
Bank;

          (c)     Settle or adjust disputes and claims directly with account
debtors for amounts, on terms and in any order that Bank considers advisable in
its commercially reasonable judgment and notify any Person owing Borrower money
of Bank's security interest in such funds and verify the amount of such account.
Borrower shall collect all payments in trust for Bank and, if requested by Bank,
immediately deliver the payments to Bank in the form received from the account
debtor, with proper endorsements for deposit;

          (d)     Make any payments and do any acts it considers necessary or
reasonable in its commercially reasonable judgment to protect its security
interest in the Collateral. Borrower shall assemble the Collateral if Bank

                                      -10-
<Page>

requests and make it available as Bank designates. Bank may enter premises where
the Collateral is located, take and maintain possession of any part of the
Collateral, and pay, purchase, contest, or compromise any Lien which appears to
be prior or superior to its security interest and pay all expenses incurred.
Borrower grants Bank a license to enter and occupy any of its premises, without
charge, to exercise any of Bank's rights or remedies;

          (e)     Apply to the Obligations any (i) balances and deposits of
Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or
the account of Borrower;

          (f)     Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell the Collateral. Bank is hereby
granted a non-exclusive, royalty-free license or other right to use, without
charge, Borrower's labels, patents, copyrights, mask works, rights of use of any
name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any similar property as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section, borrower's
rights under all licenses and all franchise agreements inure to Bank's benefit;

          (g)     Bank may place a "hold" on any account maintained with Bank
and/or deliver a notice of exclusive control, any entitlement order, or other
directions or instructions pursuant to any control agreement or similar
agreements providing control of any Collateral; and

          (h)     Dispose of the Collateral according to the Code.

     9.2  POWER OF ATTORNEY. Borrower hereby irrevocably appoints Bank as its
lawful attorney-in-fact, to be effective upon the occurrence and during the
continuance of an Event of Default, to: (i) endorse Borrower's name on any
checks or other forms of payment or security; (ii) sign Borrower's name on any
invoice or bill of lading for any Account or drafts against account debtors;
(iii) settle and adjust disputes and claims about the Accounts directly with
account debtors, for amounts and on terms Bank determines reasonable; (iv) make,
settle, and adjust all claims under Borrower's insurance policies; and (v)
transfer the Collateral into the name of Bank or a third party as the Code
permits. Borrower hereby appoints Bank as its lawful attorney-in-fact to sign
Borrower's name on any documents reasonably necessary to perfect or continue the
perfection of any security interest regardless of whether an Event of Default
has occurred until all obligations have been satisfied in full and Bank is under
no further obligation to make Credit Extensions hereunder. Bank's foregoing
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
coupled with an interest, are irrevocable until all Obligations have been fully
repaid and performed and Bank's obligation to provide Credit Extensions
terminates.

     9.3  ACCOUNT NOTIFICATION/COLLECTION. In the event that an Event of Default
occurs and is continuing, Bank may notify any Person owing Borrower money of
Bank's security interest in the funds and verify and /or collect the amount of
the Account. After the occurrence of an Event of Default, any amounts received
by Borrower shall be held in trust by Borrower for Bank, and, if requested by
Bank, Borrower shall immediately deliver such receipts to Bank in the form
received from the account debtor, with proper endorsements for deposit.

     9.4  BANK EXPENSES. Any amounts paid by Bank as provided herein are Bank
Expenses and are immediately due and payable, and shall bear interest at the
then applicable rate and be secured by the Collateral. No payments by Bank shall
be deemed an agreement to make similar payments in the future or Bank's waiver
of any Event of Default.

     9.5  BANK'S LIABILITY FOR COLLATERAL. So long as the Bank complies with
reasonable banking practices regarding the safekeeping of collateral, the Bank
shall not be liable or responsible for: (a) the safekeeping of the Collateral;
(b) any loss or damage to the Collateral; (c) any diminution in the value of the
Collateral; or (d) any act or default of any carrier, warehouseman, bailer, or
other person. Except as described above, Borrower bears all risk of loss, damage
or destruction of the Collateral.

     9.6  REMEDIES CUMULATIVE. Bank's rights and remedies under this Agreement,
the Loan Documents, and all other agreements are cumulative. Bank has all rights
and remedies provided under the Code, by law, or in equity.

                                      -11-
<Page>

Bank's exercise of one right or remedy is not an election, and Bank's waiver of
any Event of Default is not a continuing waiver. Bank's delay is not a waiver,
election, or acquiescence. No waiver hereunder shall be effective unless signed
by Bank and then is only effective for the specific instance and purpose for
which it was given.

     9.7  DEMAND WAIVER. Borrower waives demand, notice of default or dishonor,
notice of payment and nonpayment; notice of any default, nonpayment at maturity,
release, compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

11.  CHOICE OF LAW, VENUE AND JURY TRAIL WAIVER

     Massachusetts's law governs the Loan Documents without regard to principles
of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in Massachusetts; provided, however, that if for
any reason Bank cannot avail itself of such courts in the Commonwealth of
Massachusetts, Borrower accepts jurisdiction of the courts and venue in Santa
Clara County, California. NOTWITHSTANDING THE FOREGOING, THE BANK SHALL HAVE
THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWER OR ITS PROPERTY
IN THE COURTS OF ANY OTHER JURISDICTION WHICH THE BANK DEEMS NECESSARY OR
APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE THE
BANK'S RIGHTS AGAINST THE BORROWER OR ITS PROPERTY.

     BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR
CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS
OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND
ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER
INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

attorneys' fees and expenses), except for losses caused by Bank's gross
negligence or willful misconduct.

     12.3 RIGHT OF SET-OFF. Borrower and any guarantor hereby grant to Bank, a
lien, security interest and right of setoff as security for all Obligations to
Bank, whether now existing or hereafter arising upon and against all deposits,
credits, collateral and property, now or hereafter in the possession, custody,
safekeeping or control of Bank or any entity under the control of the Bank
(including a Bank subsidiary) or in transit to any of them. At any time after
the occurrence and during the continuance of an Event of Default, without demand
or notice, Bank may set off the same or any part thereof and apply the same to
any liability or obligation of Borrower and any guarantor even though unmatured
and regardless of the adequacy of any other collateral securing the Obligations.
ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH
RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO

severable from every other provision in determining the enforceability of any

understandings, representations, warranties, and negotiations between the
parties about the subject matter of this Agreement and the Loan Documents merge
into this Agreement and the Loan Documents.

     12.7 COUNTERPARTS. This Agreement may be executed in any number of
counterparts and by different parties on separate counterparts, each of which,
when executed and delivered, are an original, and all taken together, constitute
one Agreement.

     12.8 SURVIVAL. All covenants, representations and warranties made in this
Agreement continue in full force while any Obligations remain outstanding. The
obligation of Borrower in Section 12.2 to indemnify Bank shall survive until the
statute of limitations with respect to such claim or cause of action shall have
run.

     12.9 CONFIDENTIALITY. In handling any confidential information, Bank shall
exercise the same degree of care that it exercises for its own proprietary
information, but disclosure of information may be made: (i) to Bank's
subsidiaries or affiliates in connection with their business with Borrower; (ii)
to prospective transferees or purchasers of any interest in the Credit
Extensions (provided, however, Bank shall use commercially reasonable efforts in
obtaining such prospective transferee's or purchaser's agreement to the terms of
this provision); (iii) as required by law, regulation, subpoena, or other order,
(iv) as required in connection with Bank's examination or audit; and (v) as Bank

domain or in Bank's possession when disclosed to Bank, or becomes part of the
public domain after disclosure to Bank; or (b) is disclosed to Bank by a third
party, if Bank does not know that the third party is prohibited from disclosing
the information.

SECOND SUPPLEMENTAL INDENTURE dated as of December 10,
2003 (this “Supplemental Indenture”) among PLAINS ALL AMERICAN PIPELINE, L.P.,
a Delaware limited partnership (the “Partnership”), PAA FINANCE CORP., a wholly
owned subsidiary of the Partnership and a Delaware corporation (“PAA Finance”
and, together with the Partnership, the “Issuers”), and the subsidiary
guarantors signatory hereto (the “Subsidiary Guarantors”), and WACHOVIA BANK,
NATIONAL ASSOCIATION, as trustee (the “Trustee”).

 

W I T N E S S E T H:

 

WHEREAS, the Issuers have heretofore entered into an
Indenture, dated as of September 25, 2002 (the “Original Indenture”), with
Wachovia Bank, National Association, as trustee;

 

WHEREAS, the Original Indenture, as supplemented by
this Supplemental Indenture, is herein called the “Indenture”;

 

WHEREAS, under the Original Indenture, a new series of
Debt Securities may at any time be established by the Boards of Directors of
the Managing General Partner and PAA Finance in accordance with the provisions
of the Original Indenture and the form and terms of such series may be
established by a supplemental Indenture executed by the Issuers and the
Trustee;

 

WHEREAS, also under the Original Indenture, guarantors
with respect to a series of Debt Securities may be added as parties to the Indenture
by a supplemental Indenture executed by themselves, the Issuer and the Trustee;

 

WHEREAS, the Issuers propose to create under the
Indenture a new series of Debt Securities, such series to be guaranteed by the
Subsidiary Guarantors;

 

WHEREAS, additional Debt Securities of other series
hereafter established, except as may be limited in the Original Indenture as at
the time supplemented and modified, may be issued from time to time pursuant to
the Original Indenture as at the time supplemented and modified; and

 

WHEREAS, all conditions necessary to authorize the
execution and delivery of this Supplemental Indenture and to make it a valid
and binding obligation of the Issuers and the Subsidiary Guarantors have been
done or performed.

 

NOW, THEREFORE, in consideration of the agreements and
obligations set forth herein and for other good and valuable consideration, the
sufficiency of which is hereby acknowledged, the parties hereto hereby agree as
follows:

 

ARTICLE I

 

Section 1.01.               Establishment.  (a) There is hereby established a new
series of Debt Securities to be issued under the Indenture, to be designated as
the Issuers’ 55/8% Senior Notes due 2013
(the “Notes”).  As provided in Article
II hereof, the Notes shall be issued as either Series A Notes or Series B
Notes, and any Notes may have such additional designation.

 

 

(b)                                 There
are to be authenticated and delivered $250,000,000 principal amount of
Series A Notes on the Issue Date, and from time to time thereafter there
may be authenticated and delivered an unlimited principal amount of Additional
Notes.  Further, from time to time after
the Issue Date, Series B Notes may be authenticated and delivered in a
principal amount equal to the principal amount of the Series A Notes exchanged
therefor pursuant to an Exchange Offer.

 

(c)                                  The
Notes shall be issued initially in the form of one or more Global Securities in
substantially the form set out in Exhibit A hereto.  The Depositary with respect to the Notes
shall be The Depository Trust Company.

 

(d)                                 Each
Note shall be dated the date of authentication thereof and shall bear interest
from the date of original issuance thereof or from the most recent date to
which interest has been paid or duly provided for.

 

(e)                                  If
and to the extent that the provisions of the Original Indenture are duplicative
of, or in contradiction with, the provisions of this Supplemental Indenture,
the provisions of this Supplemental Indenture shall govern.

 

ARTICLE II

DEFINITIONS AND INCORPORATION BY REFERENCE

 

Section 2.01.               Definitions.  All capitalized terms used herein and not

Original Indenture.  The following are
additional definitions used in this Supplemental Indenture:

 

“Additional Interest” means all additional interest
owing on the Notes pursuant to a registration default under an Exchange and
Registration Rights Agreement.

 

“Affiliate”  of any specified Person means any other
Person directly or indirectly controlling or controlled by or under direct or
indirect common control with such specified Person. For purposes of this
definition, “control,” as used with respect to any Person, shall mean the
possession directly or indirectly of the power to direct or cause the direction
of the management or policies of such Person, whether through the ownership of
voting securities, by agreement or otherwise; and the terms “controlling,”
“controlled by” and “under common control with” shall have correlative
meanings.

 

“Attributable Indebtedness,” when used with respect to
any Sale-leaseback Transaction, means, as at the time of determination, the
present value (discounted at the rate set forth or implicit in the terms of the
lease included in such transaction) of the total obligations of the lessee for
rental payments (other than amounts required to be paid on account of property
taxes, maintenance, repairs, insurance, assessments, utilities, operating and
labor costs and other items that do not constitute payments for property
rights) during the remaining term of the lease included in such Sale-leaseback
Transaction (including any period for which such lease has been extended).  In the case of any lease that is
terminable by the lessee upon the payment of a penalty or other termination
payment, such amount shall be the lesser of the amount determined assuming
termination upon the first date such lease may be terminated (in which case the
amount shall also 

 

E-2

 

include the amount
of the penalty or termination payment, but no rent shall be considered as
required to be paid under such lease subsequent to the first date upon which it
may be so terminated) or the amount determined assuming no such termination.

 

“Capital Interests” means any and all shares,
interests, participations, rights or other equivalents (however designated) of
capital stock, including, without limitation, with respect to partnerships,
partnership interests (whether general or limited) and any other interest or

profits and losses of, or distributions of assets of, such Person.

 

“Consolidated Net Tangible Assets” means, at any date
of determination, the total amount of assets after deducting therefrom: (1) all
current liabilities (excluding (a) any current liabilities that by their terms
are extendible or renewable at the option of the obligor thereon to a time more
than 12 months after the time as of which the amount thereof is being computed;
and (b) current maturities of long-term debt); and (2) the amount, net of any
applicable reserves, of all goodwill, trade names, trademarks, patents and
other like intangible assets, all as set forth on the consolidated balance
sheet of the Partnership for its most recently completed fiscal quarter,
prepared in accordance with GAAP.

 

“Debt” means any obligation
created or assumed by any Person for the repayment of money borrowed, any
purchase money obligation created or assumed by such Person, and any guarantee
of the foregoing.

 

“Exchange and Registration Rights Agreement” means
(a) the Registration Rights Agreement among the Partnership, PAA Finance,
the Subsidiary Guarantors and the Initial Purchasers dated the Issue Date
relating to the Series A Notes issued on such date and (b) any similar
agreement that the Issuers may enter into in relation to any other Series A
Notes, in each case as such agreement may be amended or modified from time to
time.

 

“Exchange Offer” means the offer by the Issuers to the
Holders of all outstanding Transfer Restricted Securities to exchange all such
outstanding Transfer Restricted Securities held by such Holders for Series B
Notes, in an aggregate principal amount equal to the aggregate principal amount
of the Transfer Restricted Securities tendered in such exchange offer by such
Holders.

 

“Funded Debt” means all Debt maturing one year or more
from the date of the creation thereof, all Debt directly or indirectly
renewable or extendible, at the option of the debtor, by its terms or by the
terms of any instrument or agreement relating thereto, to a date one year or
more from the date of the creation thereof, and all Debt under a revolving
credit or similar agreement obligating the lender or lenders to extend credit
over a period of one year or more.

 

“Guarantee” means a guarantee of the Notes given by a
Subsidiary Guarantor pursuant to the Indenture, including all obligations under
Article IX hereof.

 

“guarantee”  means a guarantee (other than by
endorsement of negotiable instruments for collection in the ordinary course of
business), direct or indirect, in any manner (including, without limitation, by
way of a pledge of assets, or through letters of credit or reimbursement,
“claw-back,”

 

E-3

 

“make-well,” or
“keep-well” agreements in respect thereof), of all or any part of the payment
of any Debt.  The term “guarantee” used
as a verb has a corresponding meaning.

 

“Initial Purchasers” means UBS Securities LLC and the
other initial purchasers party to the initial Exchange and Registration Rights
Agreement.

 

“Issue Date” means, with respect to the Notes, the
date on which the Notes are initially issued.

Section 1.01(a) hereof, and includes both the Series A Notes and the
Series B Notes.

 

“Obligations”  means any principal, interest, liquidated
damages, penalties, fees, indemnifications, reimbursement obligations, damages

right of payment to the Notes.

ARTICLE III

THE NOTES

 

Section 3.01.               Form.  The Notes shall be issued initially in the
form of one or more Global Securities as Series A Notes, and the Series A Notes
and Trustee’s certificate of authentication shall be substantially in the form
of Exhibit A hereto, the terms of which are incorporated in and made a part of
this Supplemental Indenture, and the Issuers and the Trustee, by their
execution and delivery of this Supplemental Indenture, expressly agree to such
terms and provisions and to be bound thereby. 
The Series A Notes constituting Transfer Restricted Securities will be
resold initially only to (a) Qualified Institutional Buyers (as such term is
defined in Section 144A of the Securities Act) (“QIBs”) in reliance on Rule
144A of the Securities Act (“Rule 144A”) and (b) Persons other than U.S.
Persons (as defined under Regulation S under the Securities Act (“Regulation
S”)) (“U.S. Persons”) in reliance on Regulation S.  Thereafter, the Series A Notes may be transferred to, among
others, QIBs, purchasers in reliance upon Regulation S and institutional
“accredited investors” (as defined in subparagraph (a)(1), (2), (3) or (7) of
Rule 501 of the Securities Act (“IAIs”)) in accordance with the procedures set
forth in Rule 501 of the Securities Act, provided that any Series A Notes
constituting Transfer Restricted Securities that are transferred to IAIs who
are not QIBs shall be issued only in definitive form.  Pursuant to the terms of an Exchange and Registration Rights
Agreement, upon consummation of the Exchange Offer contemplated thereby, the
Series A Notes constituting Transfer Restricted Securities will be exchanged by
the Holders for Series B Notes to be issued by the Issuers in accordance with
Section 3.03 hereof.  The Series B Notes
shall be issued initially in the form of one or more Global Securities, and the
Series B Notes and the Trustee’s certificate of authentication shall be
substantially in the form of Exhibit A hereto.

 

Section 3.02.               Issuance
of Additional Notes.  The Issuers
may, from time to time, issue an unlimited amount of additional Series A Notes
(“Additional Notes”) under the Indenture, which shall be issued in the same
form as the Series A Notes issued on the Issue Date and which shall have
identical terms as the Series A Notes issued on the Issue Date other than with
respect to the issue date, issue price and date of first payment of
interest.  The Series A Notes
issued on the Issue Date shall be limited in aggregate principal amount to
$250,000,000.  The Series A Notes issued
on the Issue Date and any Additional Notes subsequently issued, together with
any Series B Notes issued in exchange therefor pursuant to an Exchange Offer,
shall be treated as a single series for all purposes under the Indenture, including
waivers, amendments, redemptions and offers to purchase.  If the Issuers issue additional
Series A Notes prior to the completion of an Exchange Offer, the period of
the resale restrictions applicable to any Series A Notes previously
offered and sold in reliance on Rule 144A will be automatically extended to the
last day of the period of any resale restrictions imposed on any such
additional Series A Notes.

 

Section 3.03.               Transfer
of Transfer Restricted Securities.

 

(a)                                  When
Notes are presented to the Registrar with the request to register the transfer
of such Notes or exchange such Notes for an equal principal amount of Notes of
other authorized denominations, the Registrar shall register the transfer or
make the exchange in

 

E-8

 

accordance with
Article II of the Original Indenture. 
In addition, in the case of Series A Notes that are Transfer Restricted
Securities, such request to register the transfer or make the exchange shall be
accompanied by the following additional information and documents, as
applicable, upon which the Registrar may conclusively rely:

 

(1)                                  if
such Transfer Restricted Securities are being delivered to the Registrar by a
Holder for registration in the name of such Holder, without transfer, a
certification from such Holder to that effect in substantially the form of
Exhibit C hereto; or

 

(2)                                  if
such Transfer Restricted Securities are being transferred (i) to a QIB in
accordance with Rule 144A under the Securities Act or (ii) pursuant to an
exemption from registration in accordance with Rule 144 under the Securities
Act (and based upon an opinion of counsel if the Issuers or the Trustee so
requests) or (iii) pursuant to an effective registration statement under the
Securities Act, a certification to that effect from such Holder in
substantially the form of Exhibit C hereto; or

 

(3)                                  if
such Transfer Restricted Securities are being transferred to an IAI within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act pursuant to
a private placement exemption from the registration requirements of the
Securities Act (and based upon an opinion of counsel if the Issuers or the
Trustee so requests), a certification to that effect from such Holder in
substantially the form of Exhibit C hereto and a certification from the
applicable transferee in substantially the form of Exhibit D hereto; or

 

(4)                                  if
such Transfer Restricted Securities are being transferred to Persons other than
U.S. Persons in reliance on Regulation S, a certification to that effect from
such Holder in substantially the form of Exhibit E hereto; or

 

(5)                                  if
such Transfer Restricted Securities are being transferred in reliance on
another exemption from the registration requirements of the Securities Act (and
based upon an opinion of counsel if the Issuers or the Trustee so requests), a
certification to that effect from such Holder in substantially the form of
Exhibit C hereto.

 

(b)                                 Upon
any sale or transfer of a Transfer Restricted Security (including any Transfer
Restricted Security represented by a Global Security) pursuant to Rule 144
under the Securities Act or an effective registration statement under the
Securities Act:

 

(1)                                  in
the case of any Transfer Restricted Security that is in the form of a
definitive Note, the Registrar shall permit the Holder thereof to exchange such
Transfer Restricted Security for a definitive Note that does not bear the
legend set forth in Section 3.04(a) below and rescind any restriction on the
transfer of such Transfer Restricted Security; and

 

(2)                                  in
the case of any Transfer Restricted Security represented by a Global Security,
such Transfer Restricted Security shall not be required to bear the legend set
forth in Section 3.04(a) below if all other interests in such Global Security
have been or are

 

E-9

 

concurrently being sold
or transferred pursuant to Rule 144 under the Securities Act or pursuant to an
effective registration statement under the Securities Act.

 

Notwithstanding the foregoing, upon consummation of an Exchange Offer,
the Issuers shall issue and, upon receipt of an authentication order in
accordance with Section 2.05 of the Original Indenture, the Trustee shall
authenticate Series B Notes in exchange for Series A Notes accepted for
exchange in the Exchange Offer, which Series B Notes shall not bear the legend
set forth in Section 3.04(a) below, and the Registrar shall rescind any
restriction on the transfer of such Notes, in each case unless the Holder of
such Series A Notes is either (A) a Person participating in the distribution of
the Series A Notes or (B) a Person who is an affiliate (as defined in Rule 144
under the Securities Act) of the Issuers. 
The Issuers shall identify to the Trustee such Holders of the Notes in a
written certification signed by an officer of each Issuer and, absent
certification from the Issuers to such effect, the Trustee shall assume that
there are no such Holders.

 

(c)                                  Upon
any sale or transfer of a Transfer Restricted Security (including any Transfer
Restricted Security represented by a Global Security) initially resold to
Persons other than U.S. Persons in reliance upon Regulation S pursuant to (i)
Regulation S following 40 consecutive days beginning on and including the later
of the day on which such Transfer Restricted Security was offered to Persons
other than “distributors” (as such term is defined in Regulation S) and the
date of the closing of the original offering, or (ii) an effective registration
statement under the Securities Act, the Registrar shall permit the Holder
thereof to exchange such Transfer Restricted Security for a definitive Note
that does not bear the legend set forth in Section 3.04(b) below and rescind
any restriction on the transfer of such Transfer Restricted Security.

 

Section 3.04.               Restrictive
Legends.

Person (other than Debt Securities), without in any such case making effective
provision whereby all of the Notes shall

 

E-12

 

be secured equally and
ratably with, or prior to, such Debt so long as such Debt shall be so secured.
This restriction shall not apply to:

 

(a)                                  Permitted
Liens;

 

(b)                                 any
Lien upon any property or assets created at the time of acquisition of such
property or assets by an Issuer or any Restricted Subsidiary or within one year
after such time to secure all or a portion of the purchase price for such
property or assets or Debt incurred to finance such purchase price, whether
such Debt was incurred prior to, at the time of or within one year after the
date of such acquisition;

 

(c)                                  any
Lien upon any property or assets to secure all or part of the cost of

incurred prior to, at the time of, or within one year after completion of such
construction, development, repair or improvements or the commencement of full
operations thereof (whichever is later), to provide funds for any such purpose;

 

(d)                                 any
Lien upon any property or assets existing thereon at the time of the
acquisition thereof by an Issuer or any Restricted Subsidiary (whether or not
the obligations secured thereby are assumed by an Issuer or any Restricted
Subsidiary); provided, however, that such Lien only encumbers the property or
assets so acquired;

 

(e)                                  any
Lien upon any property or assets of a Person existing thereon at the time such
Person becomes a Restricted Subsidiary by acquisition, merger or otherwise;
provided, however, that such Lien only encumbers the property or assets of such
Person at the time such Person becomes a Restricted Subsidiary;

 

(f)                                    any
Lien upon any property or assets of an Issuer or any Restricted Subsidiary in

on December 10, 2003;

 

(g)                                 Liens
imposed by law or order as a result of any proceeding before any court or
regulatory body that is being contested in good faith, and Liens which secure a
judgment or other court-ordered award or settlement as to which an Issuer or
the applicable Restricted Subsidiary, as the case may be, has not exhausted its
appellate rights;

 

(h)                                 any
extension, renewal, refinancing, refunding or replacement (or successive
extensions, renewals, refinancing, refunding or replacements) of Liens, in
whole or in part, referred to in clauses (a) through (h), inclusive, of this
Section 5.02; provided, however, that any such extension, renewal, refinancing,
refunding or replacement Lien shall be limited to the property or assets
covered by the Lien extended, renewed, refinanced, refunded or replaced and
that the obligations secured by any such extension, renewal, refinancing,
refunding or replacement Lien shall be in an amount not greater than the amount
of the obligations secured by the Lien extended, renewed, refinanced, refunded
or replaced and any expenses of the Issuers and the Restricted Subsidiaries
(including any premium) incurred in connection with such extension, renewal,
refinancing, refunding or replacement; or

 

E-13

 

(i)                                     any
Lien resulting from the deposit of moneys or evidence of indebtedness in trust
for the purpose of defeasing Debt of an Issuer or any Restricted Subsidiary.

 

Notwithstanding the foregoing provisions of this
Section 5.02, the Issuers may, and may permit any Restricted Subsidiary to,
create, assume, incur or suffer to exist any Lien upon any Principal Property
or Capital Interests of a Restricted Subsidiary to secure Debt of an Issuer or
any Person (other than Debt Securities) that is not excepted by clauses (a)
through (i), inclusive, of this Section 5.02 without securing the Notes,
provided that the aggregate principal amount of all Debt then outstanding
secured by such Lien and all other Liens not excepted by clauses (a) through
(i), inclusive, of this Section 5.02, together with all Attributable
Indebtedness from Sale-leaseback Transactions (excluding Sale-leaseback
Transactions permitted by clauses (a) through (d), inclusive, of Section 5.03),
does not exceed 10% of Consolidated Net Tangible Assets.

 

Section 5.03.               Restriction
of Sale-Leaseback Transaction.  The
Issuers will not, and will not permit any Subsidiary of the Partnership to,
engage in a Sale-Leaseback Transaction, unless:

 

(a)                                  such
Sale-Leaseback Transaction occurs within one year from the date of completion
of the acquisition of the Principal Property subject thereto or the date of the
completion of construction, development or substantial repair or improvement,
or commencement of full operations on such Principal Property, whichever is
later;

 

(b)                                 the
Sale-Leaseback Transaction involves a lease for a period, including renewals,
of not more than three years;

 

(c)                                  the
Attributable Indebtedness from that Sale-Leaseback Transaction is an amount
equal to or less than the amount the Issuers or such Subsidiary would be
allowed to incur as Debt secured by a Lien on the Principal Property subject
thereto without equally and ratably securing the Notes under Section 5.02; or

 

(d)                                 the
Issuers or such Subsidiary, within a one-year period after such Sale-Leaseback
Transaction, applies or causes to be applied an amount not less than the net
sale proceeds from such Sale-Leaseback Transaction to (A) the prepayment,
repayment, redemption, reduction or retirement of any Pari Passu Debt of an
Issuer or any Subsidiary of the Partnership, or (B) the expenditure or
expenditures for Principal Property used or to be used in the ordinary course
of business of the Partnership or its Subsidiaries.

 

Notwithstanding the
foregoing provisions of this Section 5.03, the Issuers may, and may permit any
Subsidiary of the Partnership to, effect any Sale-Leaseback Transaction that is
not excepted by clauses (a) through (d), inclusive, of this Section 5.03,
provided that the Attributable Indebtedness from such Sale-leaseback
Transaction, together with the aggregate principal amount of then outstanding
Debt (other than Debt Securities) secured by Liens upon Principal Property not
excepted by clauses (a) through (i), inclusive, of Section 5.02, does not
exceed 10% of Consolidated Net Tangible Assets.

(a)                                  Whether
or not the Partnership is then subject to the reporting requirements of Section
13 or 15(d) of the Exchange Act, the Partnership shall electronically file with
the Commission, so long as the Notes are Outstanding, the annual, quarterly and
other periodic reports that the Partnership is required to file (or would
otherwise be required to file) with the Commission pursuant to Sections 13 and
15(d) of the Exchange Act, and such documents shall be filed with the
Commission on or prior to the respective dates (the “Required Filing Dates”) by
which the Partnership is required to file (or would otherwise be required to
file) such documents, unless, in each case, such filings are not then permitted
by the Commission.

 

(b)                                 If
such filings are not then permitted by the Commission, or such filings are not
generally available on the Internet free of charge, the Issuers shall provide
the Trustee with, and the Trustee will mail to any Holder of Notes requesting
in writing to the Trustee copies of, such annual, quarterly and other periodic
reports specified in Sections 13 and 15(d) of the Exchange Act within 15 days
after the respective Required Filing Dates.

 

(c)                                  In
addition, the Issuers shall furnish to the Holders of Notes and to prospective
investors, upon the requests of Holders of Notes, any information required to
be delivered pursuant to Rule 144A(d)(4) under the Securities Act, so long as
the Notes are not freely transferable under the Securities Act.

 

(d)                                 The
Partnership shall provide the Trustee with a sufficient number of copies of all
reports and other documents and information that the Trustee may be required to
deliver to Holders of Notes under clause (b) of this Section 5.04.

 

(e)                                  Delivery
of such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute
constructive notice of any information contained therein or determinable from
information contained therein, including the Partnership’s compliance with any
of its covenants hereunder (as to which the Trustee is entitled to rely
exclusively on Officers’ Certificates).

 

Section 5.05.               Additional
Subsidiary Guarantees.  If any Subsidiary (or its successor) of the
Partnership that is not then a Subsidiary Guarantor guarantees Debt of either
of the Issuers or any other Subsidiary of the Partnership, in either case after
the Issue Date, then such Subsidiary (or successor) shall execute and deliver a
supplemental Indenture providing for the guarantee of the payment of the Notes
pursuant to Article IX hereof.

 

ARTICLE VI

SUCCESSORS

 

With respect to the
Notes, the provisions of this Article VI shall preempt the provisions of
Article X of the Original Indenture in their entirety.

 

Section 6.01.               Consolidation
and Mergers of the Issuers.  Neither
Issuer shall consolidate or amalgamate with or merge with or into any Person,
or sell, convey, transfer, lease or otherwise dispose of all or substantially
all its assets to any Person, whether in a single transaction or

 

E-15

 

a series of related
transactions, except (1) in accordance with the provisions of the Partnership
Agreement, and (2) unless: (a) either (i) such Issuer shall be the surviving
Person in the case of a merger or (ii) the resulting, surviving or transferee
Person if other than such Issuer (the “Successor Company”) shall be a
partnership, limited liability company or corporation organized and existing
under the laws of the United States, any state thereof or the District of
Columbia (provided that PAA Finance may not merge, amalgamate or consolidate
with or into another Person other than a corporation satisfying such
requirement for so long as the Partnership is not a corporation) and the
Successor Company shall expressly assume, by an indenture supplemental hereto,
executed and delivered to the Trustee, in form reasonably satisfactory to the
Trustee, the due and punctual payment of the principal of, premium, if any, and
interest (including Additional Interest, if any) on all of the Notes, and the
due and punctual performance or observance of all the other obligations under
the Indenture to be performed or observed by such Issuer; (b) immediately
after giving effect to such transaction or series of transactions, no Default
or Event of Default would occur or be continuing; (c) if the Issuer is not the
continuing Person, then each Subsidiary Guarantor, unless it has become the
Successor Company, shall confirm that its Guarantee shall continue to apply to
the obligations under the Notes and the Indenture; and (d) such Issuer shall
have delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, amalgamation, merger, sale,
conveyance, transfer, lease or other disposition and such supplemental
Indenture (if any) comply with this Section 6.01 and any other applicable
provisions of the Indenture.

 

Section 6.02.               Rights
and Duties of Successor.  In case of
any consolidation, amalgamation or merger where an Issuer is not the continuing
Person, or disposition of all or substantially all of the assets of an Issuer
in accordance with Section 6.01, the Successor Company shall succeed to and be
substituted for such Issuer with the same effect as if it had been named herein
as the respective party to the Indenture, and the predecessor entity shall be
released from all liabilities and obligations under the Indenture and the
Notes, except that no such release will occur in the case of a lease of all or
substantially all of an Issuer’s assets. 
In case of any such consolidation, amalgamation, merger, sale,
conveyance, transfer, lease or other disposition, such changes in phraseology
and form (but not in substance) may be made in the Notes thereafter to be
issued as may be appropriate.

 

Section 6.03.               Supplemental
Indenture.  Section 9.01 of the
Original Indenture is hereby amended, with respect to the Notes, by adding the
words “or a Subsidiary Guarantor’s” immediately after the word “Issuer’s” in
Section 9.01(c).

 

ARTICLE VII

DEFAULTS AND REMEDIES

 

Section 7.01.               Events
of Default.  With respect to the
Notes, the provisions of this Section 7.01 shall preempt the provisions of the
first and final paragraphs of Section 6.01 of the Original Indenture in their
entirety.

 

(a)                                  An
“Event of Default” occurs if:

 

(i)                                     the
Issuers default for 60 days in the payment
when due of interest on, or Additional Interest with respect to, the Notes;

 

E-16

 

(ii)                                  the
Issuers default in the payment when due of principal of or premium, if any, on
the Notes at maturity, upon redemption or otherwise;

 

(iii)                               failure
by an Issuer or any Subsidiary Guarantor for 30 days after receipt of notice by
the Issuers from the Trustee or to the Issuers and the Trustee by the Holders
of at least 25% in principal amount of the Notes then Outstanding to comply with any other term, covenant or warranty in the
Indenture or the Notes (provided that notice need not be given, and an
Event of Default shall occur, 30 days after any breach of the provisions
of Section 6.01 hereof);

 

(iv)                              default under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Debt of an Issuer or any of the Partnership’s Subsidiaries (or the payment of which is
guaranteed by the Partnership or any
of its Subsidiaries), whether such Debt or guarantee now exists or is created
after the Issue Date, if that default (A) is caused by a failure to pay
principal of or premium, if any, or interest on such Debt prior to the expiration of the grace period
provided in such Debt (a ”Payment Default”) or (B) results in the
acceleration of the maturity of such Debt to a date prior to its original
stated maturity, and, in each case described in clause (A) or (B), the
principal amount of any such Debt, together
with the principal amount of any other such Debt under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$25.0 million or more; provided, further,
that if any such default is cured or waived or any such acceleration rescinded,
or such Debt is repaid, within a period of 30 days from the continuation of
such default beyond the applicable grace period or the occurrence of such
acceleration, as the case may be, such Event of Default and any consequential
acceleration of the Notes shall be automatically rescinded, so long as such
rescission does not conflict with any judgment or decree;

 

(v)                                 except
as permitted by the Indenture, any Guarantee shall cease for any reason to be
in full force and effect (except as otherwise provided in the Indenture) or is
declared null and void in a judicial proceeding or any Subsidiary Guarantor, or
any Person acting on behalf of any Subsidiary Guarantor, shall deny or
disaffirm its obligations under the Indenture or its Guarantee;

 

(vi)                              an
Issuer or any Subsidiary Guarantor pursuant to or within the meaning of any
Bankruptcy Law:

 

(A)                              commences
a voluntary case,

 

(B)                                consents
to the entry of an order for relief against it in an involuntary case,

to the appointment of a custodian of it or for all or substantially all of its
property,

 

(D)                               makes
a general assignment for the benefit of its creditors, or

 

E-17

 

(E)                                 generally
is not paying its debts as they become due; or

 

(vii)                           a court of competent jurisdiction enters an order
or decree under any Bankruptcy Law that:

 

(A)                              is
for relief against an Issuer or any Subsidiary Guarantor in an involuntary
case;

 

(B)                                appoints
a custodian of an Issuer or any Subsidiary Guarantor or for all or
substantially all of the property of an Issuer or any Subsidiary Guarantor; or

 

(C)                                orders
the liquidation of an Issuer or any Subsidiary Guarantor;

 

and the order or decree remains unstayed and in effect
for 60 consecutive days.

 

(b)                                 In the case of an Event of Default arising from
Section 7.01(a)(vi) or 7.01(a)(vii) hereof involving an Issuer (and, for the
avoidance of debt, excluding any such Event of Default that involves only one
or more Subsidiary Guarantors), the principal amount of all Outstanding Notes
and interest thereon shall become due and payable immediately without further
action or notice. If any other Event of Default occurs and is continuing, the
Trustee or the Holders of at least 25% in principal amount of the then
Outstanding Notes may declare the principal amount of all the Notes and
interest thereon to be due and payable immediately by a notice in writing to
the Issuers (and to the Trustee if given by the Holders) and upon any such
declaration such principal amount and interest thereon shall be due and payable
immediately.

 

ARTICLE VIII

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

 

Section 8.01.               Option
to Effect Legal Defeasance or Covenant Defeasance.  The Issuers may, at the option of the Boards
of Directors evidenced by a Board Resolution set forth in an Officers’
Certificate, at any time, elect to have either Section 8.02 or 8.03 hereof be
applied to all outstanding Notes and Guarantees upon compliance with the
conditions set forth below in this Article VIII.

 

Section 8.02.               Legal
Defeasance and Discharge.  Upon the
Issuers’ exercise under Section 8.01 hereof of the option applicable to
this Section 8.02, each of the Issuers and the Subsidiary Guarantors shall,
subject to the satisfaction of the conditions set forth in Section 8.04 hereof,
be deemed to have been discharged from its obligations with respect to all
outstanding Notes and Guarantees on the date the conditions set forth below are
satisfied (hereinafter, “Legal Defeasance”). 
For this purpose, Legal Defeasance means that each of the Issuers shall
be deemed to have paid and discharged the entire Debt represented by the
outstanding Notes, which shall thereafter be deemed to be “Outstanding” only
for the purposes of Section 8.05 hereof and the other Sections of the
Indenture referred to in (a) and (b) below, and to have satisfied all its other
obligations under such Notes and the Indenture, and each of the Subsidiary
Guarantors shall be deemed to have discharged its obligations under its
Guarantee (and the Trustee, on demand of and at the expense of

 

E-18

 

the Issuers, shall
execute proper instruments acknowledging the same), except for the following
provisions which shall survive until otherwise terminated or discharged
hereunder:

 

(a)                                  the
rights of Holders of Outstanding Notes to receive solely from the trust fund
described in Section 8.04 hereof, and as more fully set forth in such
Section, payments in respect of the principal of, premium on, if any, interest
and Additional Interest, if any, on such Notes when such payments are due (but not the Change of Control Payment or the
payment pursuant to an Asset Sale Offer),

 

(b)                                 the
Issuers’ obligations with respect to such Notes under Sections 2.07, 2.08, 2.09
and 4.02 of the Original Indenture,

 

(c)                                  the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the
Issuers’ obligations in connection therewith,

 

(d)                                 this
Article VIII, and

 

(e)                                  the
Issuers’ rights of optional redemption under Section 4.01 hereof.

 

Subject to compliance with this Article VIII, the Issuers may
exercise their option under this Section 8.02 notwithstanding the prior
exercise of their option under Section 8.03 hereof.

 

Section 8.03.               Covenant
Defeasance.  Upon the Issuers’ exercise
under Section 8.01 hereof of the option applicable to this Section 8.03, each
of the Issuers shall, subject to the satisfaction of the conditions set forth
in Section 8.04 hereof, be released from its obligations under the covenants
contained in Sections 5.02, 5.03, 5.04 and 5.05 hereof with respect to the
Outstanding Notes on and after the date the conditions set forth in Section
8.04 are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall
thereafter be deemed not “Outstanding” for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
“Outstanding” for all other purposes hereunder (it being understood that such
Notes shall not be deemed outstanding for accounting purposes).  For this purpose, Covenant Defeasance means
that, with respect to the Outstanding Notes, the Issuers may omit to comply
with and shall have no liability in respect of any term, condition or
limitation set forth in any such covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such covenant or by reason of
any reference in any such covenant to any other provision herein or in any
other document and such omission to comply shall not constitute a Default or an
Event of Default under Section 7.01 hereof, but, except as specified above, the
remainder of the Indenture, the Guarantees and such Notes shall be unaffected
thereby.

 

Section 8.04.               Conditions
to Legal or Covenant Defeasance. 
The following shall be the conditions to the application of either
Section 8.02 or 8.03 hereof to the Outstanding Notes:

 

In order to exercise either Legal Defeasance or
Covenant Defeasance:

 

(a)                                  the
Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in Dollars, U.S. Government Obligations, or a
combination thereof, in such amounts as shall be sufficient, in the written
opinion of a nationally recognized firm of

 

E-19

 

independent public
accountants, to pay the principal of, premium on, if any, interest and
Additional Interest, if any, on the Outstanding Notes at the Stated Maturity
thereof or on the applicable redemption date, as the case may be, and the
Issuers must specify whether the Notes are being defeased to maturity or to a
particular redemption date;

 

(b)                                 in
the case of an election under Section 8.02 hereof, the Issuers shall have
delivered to the Trustee an Opinion of Counsel confirming that (i) the
Issuers have received from, or there has been published by, the Internal
Revenue Service a ruling or (ii) since the date of the Indenture, there has
been a change in the applicable federal income tax law, in either case to the
effect that, and based thereon such Opinion of Counsel shall confirm that, the
Holders of the Outstanding Notes shall not recognize income, gain or loss for
federal income tax purposes as a result of such Legal Defeasance and shall be
subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such Legal Defeasance had not
occurred;

 

(c)                                  in
the case of an election under Section 8.03 hereof, the Issuers shall have
delivered to the Trustee an Opinion of Counsel confirming that the Holders of
the Outstanding Notes shall not recognize income, gain or loss for federal
income tax purposes as a result of such Covenant Defeasance and shall be
subject to federal income tax on the same amounts, in the same manner and at
the same times as would have been the case if such Covenant Defeasance had not
occurred;

 

(d)                                 no
Default or Event of Default shall have occurred and be continuing either
(i) on the date of such deposit (other than a Default or Event of Default
resulting from the incurrence of Debt all or a portion of the proceeds of which
shall be applied to such deposit) or (ii) insofar as Section 7.01(a)(vi)
or 7.01(a)(vii) hereof is concerned, at any time in the period ending on the
91st day after the date of deposit;

 

(e)                                  such
Legal Defeasance or Covenant Defeasance shall not result in a breach or
violation of, or constitute a default under, any agreement or instrument (other
than the Notes and the Indenture) to which the Partnership or any of its Subsidiaries
is a party or by which the Partnership or any of its Subsidiaries is bound;

 

(f)                                    the
Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect
that after the 91st day following the deposit, the trust funds shall not be subject
to the effect of any applicable bankruptcy, insolvency, reorganization or
similar laws affecting creditors’ rights generally;

 

(g)                                 the
Issuers shall have delivered to the Trustee an Officers’ Certificate stating
that the deposit was not made by the Issuers with the intent of preferring the
Holders over any other creditors of the Issuers or with the intent of
defeating, hindering, delaying or defrauding any other creditors of the
Issuers; and

 

(h)                                 the
Issuers shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent provided for or
relating to the Legal Defeasance or the Covenant Defeasance have been complied
with.

 

E-20

 

Section 8.05.               Deposited
Money and U.S. Government Obligations to be Held in Trust; Other Miscellaneous
Provisions.  Subject to
Section 8.06 hereof, all money and U.S. Government Obligations (including
the proceeds thereof) deposited with the Trustee (or other qualifying trustee,
collectively for purposes of this Section 8.05, the “Trustee”) pursuant to
Section 8.04 hereof in respect of the outstanding Notes shall be held in
trust and applied by the Trustee, in accordance with the provisions of such
Notes and the Indenture, to the payment, either directly or through any paying
agent (including an Issuer acting as paying agent) as the Trustee may
determine, to the Holders of such Notes of all sums due and to become due
thereon in respect of principal, premium on, if any, interest and Additional
Interest, if any, but such money need not be segregated from other funds except
to the extent required by law.

 

The Issuers shall pay and
indemnify the Trustee against any tax, fee or other charge imposed on or
assessed against the cash or U.S. Government Obligations deposited pursuant to
Section 8.04 hereof or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the
account of the Holders of the Outstanding Notes.

 

Anything in this
Article VIII to the contrary notwithstanding, the Trustee shall deliver or
pay to the Issuers from time to time upon the written request of the Issuers
any money or U.S. Government Obligations held by it as provided in
Section 8.04 hereof which, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under
Section 8.04(a) hereof), are in excess of the amount thereof that would
then be required to be deposited to effect an equivalent Legal Defeasance or
Covenant Defeasance.

 

Section 8.06.               Repayment
to Issuers.  Any money deposited
with the Trustee or any paying agent, or then held by the Issuers, in trust for
the payment of the principal of, premium on, if any, interest or Additional
Interest, if any, on any Note and remaining unclaimed for two years after such
principal, premium, if any, interest or Additional Interest, if any, has become
due and payable shall be paid to the Issuers on their written request or (if
then held by the Issuers) shall be discharged from such trust; and the Holder
of such Note shall thereafter, as an unsecured creditor, look only to the
Issuers for payment thereof, and all liability of the Trustee or such paying
agent with respect to such trust money, and all liability of the Issuers as
trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such paying agent, before being required to make any such repayment,
may at the expense of the Issuers cause to be published once, in the New York
Times and The Wall Street Journal (national edition), notice that such money
remains unclaimed and that, after a date specified therein, which shall not be
less than 30 days from the date of such notification or publication, any
unclaimed balance of such money then remaining shall be repaid to the Issuers.

 

Section 8.07.               Reinstatement.  If the Trustee or paying agent is unable to
apply any Dollars or U.S. Government Obligations in accordance with
Section 8.02 or 8.03 hereof, as the case may be, by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, then the Issuers’ obligations under the
Indenture and the Notes and the Subsidiary Guarantors’ obligations under the
Guarantees shall be revived and reinstated as though no deposit had occurred
pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or
paying agent is permitted to apply all such money in accordance with
Section 8.02 or 8.03 hereof, as the case may be; provided, however,
that, if the Issuers make any

 

E-21

 

payment of principal of,
premium on, if any, interest or Additional Interest, if any, on any Note
following the reinstatement of their obligations, the Issuers shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or paying agent.

 

ARTICLE IX

SUBSIDIARY GUARANTEES

 

Section 9.01.               Subsidiary
Guarantees.  (a)  Each Subsidiary Guarantor hereby jointly and
severally unconditionally and irrevocably guarantees on a senior basis to each
Holder and to the Trustee and its successors and assigns (i) the full and
punctual payment of principal, premium, if any, interest, and Additional
Interest, if any, with respect to, the Notes when due, whether at maturity, by
acceleration, by redemption or otherwise, and all other monetary obligations of
the Issuers under the Indenture (including obligations to the Trustee) and the
Notes and (ii) the full and punctual performance within applicable grace
periods of all other obligations of the Issuers under the Indenture and the
Notes (all the foregoing being hereinafter collectively called the “Note
Obligations”).  Each Subsidiary
Guarantor further agrees that the Note Obligations may be extended or renewed,
in whole or in part, without notice or further assent from each such Subsidiary
Guarantor, and that each such Subsidiary Guarantor shall remain bound under
this Article IX notwithstanding any extension or renewal of any Note
Obligation.

 

(b)                                 Each
Subsidiary Guarantor waives presentation to, demand of, payment from and
protest to the Issuers of any of the Note Obligations and also waives notice of
protest for nonpayment.  Each Subsidiary
Guarantor waives notice of any Default or Event of Default under the Notes or
the Note Obligations.  The obligations
of each Subsidiary Guarantor hereunder shall not be affected by (i) the
failure of any Holder or the Trustee to assert any claim or demand or to
enforce any right or remedy against the Issuers or any other Person under the
Indenture, the Notes or any other agreement or otherwise; (ii) any
extension or renewal of any thereof; (iii) any rescission, waiver,
amendment or modification of any of the terms or provisions of the Indenture,
the Notes or any other agreement; (iv) the release of any security held by
any Holder or the Trustee for the Note Obligations or any of them; (v) the
failure of any Holder or Trustee to exercise any right or remedy against any
other guarantor of the Note Obligations; or (vi) any change in the
ownership of such Subsidiary Guarantor, except as provided in Section 9.02
hereof.

 

(c)                                  Each
Subsidiary Guarantor further agrees that its Guarantee herein constitutes a
guarantee of payment, performance and compliance when due (and not a guarantee
of collection) and waives any right to require that any resort be had by any
Holder or the Trustee to any security held for payment of the Note Obligations.

 

(d)                                 The
obligations of each Subsidiary Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason other than
indefeasible payment in full of the Note Obligations, including any claim of waiver,
release, surrender, alteration or compromise, and shall not be subject to any
defense of setoff, counterclaim, recoupment or termination whatsoever or by
reason of the invalidity, illegality or unenforceability of the Note
Obligations or otherwise.  Without
limiting the generality of the foregoing, the obligations of each Subsidiary
Guarantor herein shall not be discharged or impaired or otherwise affected by
the failure of any Holder or the Trustee to assert any claim or demand or to
enforce any remedy under the

 

E-22

 

Indenture, the
Notes or any other agreement, by any waiver or modification of any thereof, by
any default, failure or delay, willful or otherwise, in the performance of the
obligations, or by any other act or thing or omission or delay to do any other
act or thing which may or might in any manner or to any extent vary the risk of
any Subsidiary Guarantor or would otherwise operate as a discharge of any
Subsidiary Guarantor as a matter of law or equity.

 

(e)                                  Each
Subsidiary Guarantor further agrees that its Guarantee herein shall continue to
be effective or be reinstated, as the case may be, if at any time payment, or
any part thereof, of principal, premium, if any, interest or Additional Interest,
if any, with respect to any Note Obligation is rescinded or must otherwise be
restored by any Holder or the Trustee upon the bankruptcy or reorganization of
either of the Issuers or otherwise.

 

(f)                                    In
furtherance of the foregoing and not in limitation of any other right which any
Holder or the Trustee has at law or in equity against any Subsidiary Guarantor
by virtue hereof, upon the failure of the Issuers to pay the principal,
premium, if any, interest or Additional Interest, if any, with respect to any
Note Obligation when and as the same shall become due, whether at maturity, by
acceleration, by redemption or otherwise, or to perform or comply with any
other Note Obligation, each Subsidiary Guarantor hereby promises to and shall
forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an
amount equal to the sum of (i) the unpaid principal amount of such Note
Obligations, (ii) accrued and unpaid interest on such Note Obligations
(but only to the extent not prohibited by law) and (iii) all other
monetary Note Obligations of the Issuers to the Holders and the Trustee.

 

(g)                                 Each
Subsidiary Guarantor agrees that it shall not be entitled to any right of
subrogation in relation to the Holders in respect of any Note Obligations
guaranteed hereby until payment in full of all Note Obligations.  Each Subsidiary Guarantor further agrees
that, as between it, on the one hand, and the Holders and the Trustee, on the
other hand, (i) the maturity of the Note Obligations guaranteed hereby may
be accelerated as provided in Article VII hereof for the purposes of any
Subsidiary Guarantor’s Guarantee herein, notwithstanding any stay, injunction
or other prohibition preventing such acceleration in respect of the Note
Obligations guaranteed hereby, and (ii) in the event of any declaration of
acceleration of such obligations as provided in Article VII hereof, such
Note Obligations (whether or not due and payable) shall forthwith become due
and payable by such Subsidiary Guarantor for the purposes of this Section 9.01.

 

(h)                                 Each
Subsidiary Guarantor also agrees to pay any and all costs and expenses
(including reasonable attorneys’ fees) incurred by the Trustee or any Holder in
enforcing any rights under this Section 9.01.

 

Section 9.02.               Limitation
on Liability.  Any term or provision
of the Indenture to the contrary notwithstanding, the maximum, aggregate amount
of the Note Obligations guaranteed hereunder by any Subsidiary Guarantor shall
not exceed the maximum amount that, after giving effect to all other contingent
and fixed liabilities of such Subsidiary Guarantor and to any collections from
or payments made by or on behalf of any other Subsidiary Guarantor in respect
of its obligations under its Guarantee, can be hereby guaranteed without
rendering the Indenture, as it relates to any Subsidiary Guarantor, voidable
under applicable law relating to fraudulent conveyance or fraudulent transfer.

Section 9.03.               Successors
and Assigns.  This Article IX
shall be binding upon each Subsidiary Guarantor and, except as provided in
Section 9.07, its successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any
transfer or assignment of rights by any Holder or the Trustee, the rights and
privileges conferred upon that party in the Indenture and in the Notes shall
automatically extend to and be vested in such transferee or assignee, all
subject to the terms and conditions of the Indenture.

 

Section 9.04.               No
Waiver.  Neither a failure nor a
delay on the part of either the Trustee or the Holders in exercising any right,
power or privilege under this Article IX shall operate as a waiver
thereof, nor shall a single or partial exercise thereof preclude any other or
further exercise of any right, power or privilege.  The rights, remedies and benefits of the Trustee and the Holders
herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article IX at
law, in equity, by statute or otherwise.

 

Section 9.05.               Modification.  No modification, amendment or waiver of any
provision of this Article IX, nor the consent to any departure by any
Subsidiary Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice to or demand on any
Subsidiary Guarantor in any case shall entitle such Subsidiary Guarantor to any
other or further notice or demand in the same, similar or other circumstances.

 

Section 9.06.               Execution
of Supplemental Indenture for Future Subsidiary Guarantors.  Each Subsidiary which is required to become
a Subsidiary Guarantor pursuant to Section 5.05 hereof shall promptly
execute and deliver to the Trustee a supplemental Indenture in substantially
the form of Exhibit B hereto pursuant to which such Subsidiary shall
become a Subsidiary Guarantor under this Article IX and shall guarantee the
Note Obligations.  Concurrently with the
execution and delivery of such supplemental Indenture, the Issuers shall
deliver to the Trustee an Opinion of Counsel to the effect that such
supplemental Indenture has been duly authorized, executed and delivered by such
Subsidiary and that, subject to the application of bankruptcy, insolvency,
moratorium, fraudulent conveyance or transfer and other similar laws relating
to creditors’ rights generally and to the principles of equity, whether
considered in a proceeding at law or in equity, the Guarantee of such
Subsidiary Guarantor is a legal, valid and binding obligation of such
Subsidiary Guarantor, enforceable against such Subsidiary Guarantor in
accordance with its terms.

 

Section 9.07.               Release
of Guarantee.  Provided that no
Default shall have occurred and shall be continuing under the Indenture, the
Guarantee of a Subsidiary Guarantor under this Article IX shall terminate and
be of no further force and effect, and such Subsidiary Guarantor shall be
released from the Indenture and all Note Obligations, upon the following
events:

 

(a)                                  upon
any sale or other disposition of all or substantially all of the assets of such
Subsidiary Guarantor (including by way of merger, consolidation or otherwise)
to any Person that is not an Affiliate of either of the Issuers (provided such
sale or other disposition is not prohibited by the Indenture);

 

E-24

 

(b)                                 upon
any sale or other disposition of all of the Equity Interests of a Subsidiary
Guarantor, to any Person that is not an Affiliate of either of the Issuers; or

 

(c)                                  following
delivery of a written notice of such release or discharge from the Guarantee by
the Issuers to the Trustee, upon the release or discharge of all guarantees by
such Subsidiary Guarantor of any Debt of the Issuers and any Subsidiary of the
Partnership (other than Debt Securities issued on or after the Issue Date).
