enforcement, including attorney's fees and out-of-pocket expenses and all other
expenses and liabilities resulting therefrom, shall be borne solely by Borrower
whether the same are incurred by the Lenders or Borrower.

8.4. Verification of Accounts. Whether or not an Event of Default has

remove from Borrower's premises all of the foregoing and keep and retain the
same in Lenders' possession until the Loans and other Obligations secured hereby
shall have been fully paid and discharged and the Lenders have no further
obligation under the Agreement. The provisions of this Section shall not be
deemed to diminish or contravene the security interest of the Lenders in the
Borrower's General Intangibles or in the property, materials, and interests

withdraw shares in the Mutual Fund Account to the extent needed to meet
Borrower's good faith and reasonable projections of its short term requirements
for working capital. Lenders shall give their consent to the issuer of the
Mutual Fund Account, and/or its transfer agent, for withdrawals permitted

Default hereunder, notwithstanding the effect of such possession, collection,
settlement, compromise or sale upon the business of Borrower. Said waiver shall
include all causes of action and claims which may result from the exercise of
the power of attorney conferred upon Lenders in Section 8.9. The failure at any
time or times hereafter to require strict performance by Borrower of any of the
provisions, warranties, terms and conditions contained in this Agreement or any
other agreement, document or instrument now or hereafter executed by Borrower,

Inventory and to make the same available to the Lenders at a place to be
designated by the Lenders which is reasonably convenient to both parties. Unless
the Collateral is perishable or threatens to decline speedily in value, or is of
a style customarily sold on a recognized market, the Lenders will give Borrower

disposition thereof is to be made. The requirement of reasonable notice shall be

evidence of Debt held by the Lenders, and each and every remedy shall be
cumulative and shall be in addition to every other remedy given hereunder or now
or hereafter existing in law or in equity.

Exercise or omission to exercise any right of the Lenders shall not affect any
subsequent right of the Lenders to exercise the same.

Borrower waives, to the fullest extent permitted under applicable law,
notice prior to Lenders' taking possession or control of any of the Collateral
or any bond or security that might be required by any court prior to allowing
Lenders to exercise any of Lenders' remedies, including, without limitation, the
issuance of an immediate writ of possession.

Borrower agrees that the Lenders may apply the net proceeds received from
the Collateral toward satisfaction of the Obligations, and the manner, extent

Obligations, and the other obligations and liabilities of the Borrower to the
Lenders shall be distributed as required by Applicable Laws.

10.3. Right of Set-Off. Upon the occurrence and during the continuance of
any Event of Default, Lenders may, and are hereby authorized by Borrower, at any
time and from time to time, to the fullest extent permitted by Applicable Laws,
and without advance notice to Borrower (any such notice being expressly waived
by Borrower), set-off and apply any and all deposits (general or special, time
or demand, provisional or final) at any time held and any other indebtedness at
any time owing by Lenders to, or for the credit or the account of, Borrower
against any or all of the Loans and Obligations and other liabilities and
obligations of Borrower now or hereafter existing whether or not such
obligations have matured and irrespective of whether Lenders have exercised any
other rights that they have or may have with respect to such Loans and
Obligations and other liabilities and obligations, including, without
limitation, any acceleration rights. The aforesaid right of set-off may be
exercised by Lenders against Borrower or against any trustee in bankruptcy,
debtor in possession, assignee for the benefit of the creditors, receiver, or
execution, judgment or attachment creditor of Borrower, notwithstanding the fact
that such right of set-off shall not have been exercised by Lenders prior to the
making, filing or issuance, or service upon Lenders of, or of notice of, any
such petition; assignment for the benefit of creditors; appointment or
application for the appointment of a receiver; or issuance of execution,
subpoena, order or warrant. Lenders agree to notify Borrower after any such
set-off and application, provided that the failure to give such notice shall not
affect the validity of such set-off and application. The rights of Lenders under
this Section are in addition to the other rights and remedies (including,
without limitation, other rights of setoff) which Lenders may have.

12.3. Legal Counsel. Borrower acknowledges and agrees that legal counsel
to Lenders does not represent Borrower as Borrower's attorney, that Borrower has
retained (or has had an opportunity to retain) counsel of its own choice and has
not and will not rely upon any advice from Lenders' counsel. In no event shall
Borrower's reimbursement of expenses pursuant to this Agreement (even if
effected by payment directly by Borrower to Lenders' counsel) be deemed to
establish any attorney-client relationship between Borrower and Lenders'
counsel.

12.4. Intentionally deleted.

12.5. No Waiver. No waiver of any Event of Default hereunder, and no
waiver of any default or Event of Default under any other Loan Document shall
extend to or shall affect any subsequent or other then existing default or shall
impair any rights, remedies or powers of Lenders. No delay or omission of
Lenders or any subsequent holder of the Notes to exercise any right, remedy,
power or privilege hereunder after the occurrence of such default or Event of
Default shall be construed as a waiver of any such default, or acquiescence
therein.

12.6. Headings. Except for the definitions set forth in Section 1, the
headings of the articles, sections, paragraphs and subdivisions of this
Agreement are for convenience of reference only, are not to be considered a part
hereof, and shall not limit or otherwise affect any of the terms hereof.

12.7. No Usury. In no event shall the amount of interest due or payable on
the Loans under this Agreement or the Notes exceed the Maximum Rate and in the
event any such payment is inadvertently paid by the Borrower or inadvertently
received by the Lenders, then such excess sum shall be credited as payment of
principal, unless the Borrower elects to have such excess sum refunded to the
Borrower forthwith. It is the express intent of the parties that the Borrower
not pay and the Lenders not receive, directly or indirectly, interest in excess
of that which may be legally paid by the Borrower under Applicable Law.

12.8. Marshaling of Assets; Payments Set Aside. Lenders shall be under no
obligation to marshal any assets or securities in favor of Borrower or any
Guarantor or any other Person or against or in payment of any or all of the
Obligations. To the extent that sum credited against the Obligations is
subsequently invalidated, declared to be fraudulent or preferential, set aside
or required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then to the
extent of such recovery, the Obligations or part thereof originally intended to
be satisfied, and, to the extent permitted under applicable law, all Liens,
rights and remedies therefor, shall be revived and continued in full force and
effect as if such payment had not been made or such enforcement or setoff had
not occurred.

12.9. Survival of Covenants. All covenants, agreements, representations
and warranties made herein and in certificates or reports delivered pursuant
hereto shall be deemed to have been material and relied on by Lenders,
notwithstanding any investigation made by or on behalf of Lenders, and shall
survive the execution and delivery to Lenders of any Note or Loan Document.

12.10. Addresses. Any notice or demand which by any provision of this
Agreement is required or provided to be given shall be deemed to have been
sufficiently given or served for all purposes by (i) being delivered in person
to the party to whom the notice or demand is directed, (ii) by being sent as
certified or registered mail, postage prepaid, return receipt requested, or
(iii) if sent by Federal Express or overnight United States Mail or other
national overnight carrier, in each event to the following address: If to
Borrower, ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; or if any other address
shall at any time be designated by Borrower in writing to the holders of record
of the Note at the time of such designation to such other address; and if to
Lenders, to Agent Lender at c/o The Retirement Systems of Alabama, ▇▇▇ ▇▇▇▇▇
▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇, Attn: ▇▇▇▇▇▇
▇▇▇▇▇▇▇, Esq., Director of Fixed Income and ▇▇. ▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Assistant
Director of Fixed Income; or if any other address shall at any time be
designated in writing to Borrower, to such other address. Notwithstanding the
foregoing, no notice shall be effective as to Lenders until actually received by
Lenders. Any written notice that is not sent in conformity with

the provisions hereof shall nevertheless be effective on the date that such
notice is actually received by the noticed party.

12.11. The Lenders' principal place of business is located in Montgomery
County in the State of Alabama, and the Borrower acknowledges that the Loans are
payable to the Lenders at their offices in Montgomery, Alabama and the Borrower
agrees that this Agreement shall be held by Lenders at such principal place of
business, and the location for payment of the Loans and the holding of this
Agreement by Lenders thereat shall constitute sufficient minimum contacts of
Borrower with Montgomery County and the State of Alabama for the purpose of
conferring jurisdiction upon the federal and state courts presiding in such
county and state. Borrower consents that any legal action or proceeding arising
hereunder may be brought in the Circuit Court of the State of Alabama,
▇▇▇▇▇▇▇▇▇▇ County, Alabama or the United States District Court for the Middle
District of Alabama and assents and submits to the personal jurisdiction of any
such court in any action or proceeding involving this Agreement, the Loans or
any Loan Documents. Nothing herein shall limit the jurisdiction of any other
court.

12.12. Continuing Obligation; Benefits. This Agreement, and each and every
provision hereof, is a continuing obligation and shall (i) be binding upon the
Borrower and the Lenders, their successors and assigns, and (ii) inure to the
benefit of and be enforceable by the Borrower and Lenders and their successors
and assigns; provided, that the Borrower may not assign all or any part of this
Agreement without the prior written consent of Lenders, which consent may be
granted or withheld in the sole discretion of Lenders.

12.13. Controlling Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of Alabama; provided, however, that if
any of the Collateral shall be located in any jurisdiction other than Alabama,
the laws of such jurisdiction shall govern the method, manner and procedure for
foreclosure of Lenders' lien upon such Collateral and the enforcement of
Lenders' other remedies in respect of such Collateral to the extent that the
laws of such jurisdiction are different from or inconsistent with the laws of
Alabama.

12.14. Standard of Review. Any document, writing or instrument required or
permitted to be delivered to Lenders under this Agreement shall be deemed
satisfactory only if approved by Lenders in the exercise of its sole discretion,
and any act or approval permitted to be done by Lenders under this Agreement
shall be in Lenders' sole discretion. Where in this Agreement reference is made
to Lenders' "discretion", or "sole discretion", said reference shall mean that
with respect to the matter so designated, Lenders shall have the absolute right
to make decision with respect thereto and shall not be subject to any standard
of good faith, fair dealing, reasonableness, or any other standard implied by
any court or imposed by law, it being the intention of the parties that the
decision of the Lenders with respect to said matter shall be absolutely final
and binding.

12.15. Participation. Borrower acknowledges that Lenders may, at their
option, sell participation interests in the Loans to participating lenders,
provided that, Borrower, shall not be

required to pay any fees or expenses directly related to the selling of such
participation interests. The amounts of any such participations shall be
determined solely by the Lenders. Borrower agrees with each present and future
participant in the Loans, the names and addresses of which will be furnished to
Borrower, that if an Event of Default should occur, each present and future
participant shall have all of the rights and remedies of Lenders with respect to
any deposit due from any participant to Borrower. The execution by a participant
of a participation agreement with Lenders, and the execution by Borrower of this
Agreement, regardless of the order of execution, shall evidence an agreement
between Borrower and said participant in accordance with the terms of this
Section.

12.16. Miscellaneous. This Agreement and the instruments and agreements
referred to herein or called for hereby supersede and incorporate all
representations, promises, and statements, oral or written, made by the Lenders
in connection with the Loans. This Agreement may not be varied, altered, or
amended except by a written instrument executed by an authorized officer of the
Lenders. This Agreement may be executed in any number of counterparts, each of
which, when executed and delivered, shall be an original, but such counterparts
shall together constitute one and the same instrument. Any provision in this
Agreement which may be unenforceable or invalid under any law shall be
ineffective to the extent of such unenforceability or invalidity without
affecting the enforceability or validity of any other provisions hereof.

12.17. General Waivers. To the fullest extent permitted by Applicable Law,
Borrower waives (i) presentment, demand and protest and notice of presentment,
protest, default, nonpayment, maturity, release, compromise, settlement,
extension or renewal of any or all commercial paper, accounts, contract rights,
documents, instruments, chattel paper and guaranties at any time held by Lenders
on which Borrower may in any way be liable; (ii) notice prior to Lenders' taking
possession or control of any of the Collateral or any bond or security which
might be required by any court prior to allowing Lenders to exercise any of
Lenders' remedies, including the issuance of an immediate writ of possession;
(iii) the benefit of all valuation, appraisement and exemption laws; (iv) any
right Borrower may have upon payment in full of the Obligations to require
Lenders to terminate their security interest in the Collateral until the
execution by Borrower of an agreement indemnifying Lenders from any loss or
damage Lenders may incur as the result of dishonored checks or other items of
payment received by Lenders from Borrower or any Account Debtor and applied to
the Obligations; and (v) notice of Lenders' acceptance hereof or of any Loan
Document.

12.18. Maximum Interest. Regardless of any provision contained in this
Agreement or any of the Loan Documents, in no event shall the aggregate of all
amounts that are contracted for, charged or collected pursuant to the terms of
this Agreement, the Notes or any of the Loan Documents, and that are deemed
interest under Applicable Law, exceed the Maximum Rate. No provision of this
Agreement or in any of the Loan Documents or the exercise by Lenders of any
right hereunder or under any Loan Document or the prepayment by Borrower of any
of the Obligations or the occurrence of any contingency whatsoever, shall
entitle Lenders to charge or receive, or to require Borrower to pay, interest or
any amounts deemed interest by Applicable Law (such amounts being referred to
herein collectively as "Interest") in excess of the Maximum Rate, and all
provisions hereof or in any Loan Document which may purport to require Borrower
to pay Interest exceeding

the Maximum Rate shall be without binding force or effect to the extent only of
the excess of Interest over such Maximum Rate. Any Interest charged or received
in excess of the Maximum Rate ("Excess"), shall be conclusively presumed to be
the result of an accident and bona fide error, and shall, to the extent received
by Lenders, at the option of Lenders, promptly either be applied to reduce the
principal amount of the Obligations or returned to Borrower. The right to
accelerate the maturity of any of the Obligations does not include the right to
accelerate unaccrued interest, and no such interest will be collected by
Lenders. All monies paid to Lenders hereunder or under any of the Loan Documents
shall be subject to any rebate of unearned interest as and to the extent
required by Applicable Law. By the execution of this Agreement, Borrower
covenants that (i) the credit or return of any Excess shall constitute the
acceptance by Borrower of such Excess, and (ii) Borrower shall not seek or
pursue any other remedy, legal or equitable, against Lenders, based in whole or
in part upon contracting for, charging or receiving any Interest in excess of
the Maximum Rate.

12.19. Cross-Default and Cross-Collateralization. All Loans are
cross-defaulted and cross-collateralized in all respects.

12.20. Agent Lender. The Lenders have selected The Teachers' Retirement
System of Alabama as its agent with respect to the Loans for the purposes set
forth herein and for any other such purposes as may be determined by the Lenders
from time to time.

12.21. Waiver of Right to Trial by Jury. Borrower and Lenders hereby waive
any right to trial by jury on any claim, counterclaim, setoff, demand, action or
cause of action (a) arising out of or in any way pertaining or relating to this
Agreement, the Notes, the Loan Documents, or any other instrument, document or
agreement executed or delivered in connection with this agreement or (b) in any
way connected with or pertaining or related to or incidental to any dealings of
the parties hereto with respect to this agreement, the Notes, the Loan
Documents, or any other instrument, document or agreement executed or delivered
in connection herewith or in connection with the transactions related thereto or
contemplated thereby or the exercise of any party's rights and remedies
thereunder, in all of the foregoing cases whether now existing or hereafter
arising, and whether sounding in contract, tort or otherwise. Borrower and
Lenders agree that any or all of them may file a copy of this paragraph with any
court as written evidence of the knowing, voluntary and bargained agreement
between the parties irrevocably to waive trial by jury, and that any dispute or
controversy whatsoever between them shall instead be tried in a court of
competent jurisdiction by a judge sitting without a jury.
