in this Agreement are defined in Schedule B; and references to a “Schedule” or an “Exhibit” are, unless otherwise specified, to a Schedule or an Exhibit attached to this Agreement. 

Section 2. SALE AND PURCHASE OF NOTES. 

Subject to the terms and conditions of this Agreement, the Company will issue and sell to each Purchaser and each Purchaser will purchase

Purchasers’ obligations hereunder are several and not joint obligations and no Purchaser shall have any liability to any Person for the performance or non-performance of any obligation by any other Purchaser hereunder. 

Section 3. CLOSING. 

The sale and purchase of the Notes to be purchased by each Purchaser shall occur at the offices of Baker Botts L.L.P., 910 Louisiana Street, Houston,
Texas 77002, at 10:00 a.m., Central time, at a closing (the “Closing”) on December 22, 2011 or on such other Business Day thereafter on or prior to December 31, 2011 as may be agreed upon by the Company and the Purchasers. At
the Closing the Company will deliver to each Purchaser the Notes to be purchased by such Purchaser in the form of a single Note (or such greater number of Notes in denominations of at least $100,000 as such Purchaser may request) dated the date of
the Closing and registered in such Purchaser’s name (or in the name of its nominee), against delivery by such Purchaser to the Company or its order of immediately available funds in the amount of the purchase price therefor by wire transfer of
immediately available funds for the account of the Company to account number 183555 at Regions Bank, 1900 5th Avenue North, Birmingham, Alabama 35203. If at the Closing the Company shall fail to tender such Notes to any Purchaser as provided above

been fulfilled to such Purchaser’s satisfaction, such Purchaser shall, at its election, be relieved of all further obligations under this Agreement, without thereby waiving any rights such

was not in effect on the date hereof. If requested by such Purchaser, such Purchaser shall have received an Officer’s Certificate certifying as to such matters of fact as such Purchaser may reasonably specify to enable such Purchaser to

jurisdiction in which such qualification is required by law, other than those jurisdictions as to which the failure to be so qualified or in good standing could not, individually or in the aggregate, reasonably be


  
 - 3 -








 
expected to have a Material Adverse Effect. The Company has the corporate power and authority to own or hold under lease the properties it purports to own or hold under lease, to transact the
business it transacts and proposes to transact, to execute and deliver this Agreement and the Notes and to perform the provisions hereof and thereof. 
 Section 5.2 Authorization, Etc. This Agreement and the Notes have been duly authorized by all necessary corporate action on the part of the Company, and this Agreement constitutes, and upon
execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by (i) applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors’ rights generally and (ii) general principles of equity (regardless of whether such enforceability is considered in a
proceeding in equity or at law). 
 Section 5.3 Disclosure. This Agreement, the Notes and the documents,
certificates or other writings delivered to the Purchasers by or on behalf of the Company in connection with the transactions contemplated hereby and identified in Schedule 5.3, and the financial statements listed in Schedule 5.5
(this Agreement, the Notes and such documents, certificates or other writings and such financial statements delivered to each Purchaser being referred to, collectively, as the “Disclosure Documents”), taken as a whole, do not
contain any untrue statement of a material fact or omit to state any material fact (other than general economic and geo-political conditions) necessary to make the statements therein not misleading in light of the circumstances under which they were
made. Except as disclosed in the Disclosure Documents, since September 30, 2011, there has been no change in the financial condition, operations, business, properties or prospects of the Company or any Subsidiary except changes that
individually or in the aggregate could not reasonably be expected to have a Material Adverse Effect. There is no fact (other than general economic and geo-political conditions) known to the Company that could reasonably be expected to have a
Material Adverse Effect that has not been set forth herein or in the Disclosure Documents. 
 Section 5.4 Subsidiaries;
Affiliates. Schedule 5.4 contains (except as noted therein) complete and correct lists (i) of the Company’s Affiliates and (ii) of the Company’s directors and senior officers. The Company has no Subsidiaries.

 Section 5.5 Financial Statements; Material Liabilities. The Company has delivered to each Purchaser copies of the
financial statements of the Company listed on Schedule 5.5. All of said financial statements (including in each case the related schedules and notes) fairly present in all material respects the financial position of the Company as of the
respective dates specified in such Schedule and the results of its operations and cash flows for the respective periods so specified and have been prepared in accordance with GAAP consistently applied throughout the periods involved except as set
forth in the notes thereto (subject, in the case of any interim financial statements, to normal year-end adjustments). The Company does not have any Material liabilities that are not disclosed on such financial statements or otherwise disclosed in
the Disclosure Documents. 
 Section 5.6 Compliance with Laws, Other Instruments, Etc. The execution, delivery and
performance by the Company of this Agreement and the Notes will not 

  
 - 4 -








 
(i) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien in respect of any property of the Company under, any indenture, mortgage, deed
of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other agreement or instrument to which the Company is bound or by which the Company or any of its properties may be bound or subject, (ii) conflict with
or result in a breach of any of the terms, conditions or provisions of any order, judgment, decree, or ruling of any court, arbitrator or Governmental Authority applicable to the Company or (iii) violate any provision of any statute or other
rule or regulation of any Governmental Authority applicable to the Company. 
 Section 5.7 Governmental Authorizations,
Etc. No consent, approval or authorization of, or registration, filing or declaration with, any Governmental Authority is required in connection with the execution, delivery or performance by the Company of this Agreement or the Notes other than
the approval of the Alabama Public Service Commission which, pursuant to an order dated October 4, 2011 (Informal Docket U-5036), has already been obtained and is in full force and effect. 

Section 5.8 Litigation; Observance of Agreements, Statutes and Orders. (a) Other than as set forth in the Disclosure
Documents, there are no actions, suits, investigations or proceedings pending or, to the knowledge of the Company, threatened against or affecting the Company or any property of the Company in any court or before any arbitrator of any kind or before
or by any Governmental Authority that, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect. 
 (b) The Company is not (i) in default under any term of any agreement or instrument to which it is a party or by which it is bound, (ii) in violation of any order, judgment, decree or ruling of
any court, arbitrator or Governmental Authority or (iii) other than as set forth in the Disclosure Documents, in violation of any applicable law, ordinance, rule or regulation of any Governmental Authority (including without limitation
Environmental Laws, the USA PATRIOT Act or any of the other laws and regulations that are referred in Section 5.16), which default or violation, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect.

 Section 5.9 Taxes. The Company has filed all tax returns that are required to have been filed in any
jurisdiction, and has paid all taxes shown to be due and payable on such returns and all other taxes and assessments levied upon it or its properties, assets, income or franchises, to the extent such taxes and assessments have become due and payable
and before they have become delinquent, except for any taxes and assessments (i) the amount of which is not individually or in the aggregate Material or (ii) the amount, applicability or validity of which is currently being contested in
good faith by appropriate proceedings and with respect to which the Company has established adequate reserves in accordance with GAAP. The Company knows of no basis for any other tax or assessment that could reasonably be expected to have a Material
Adverse Effect. The charges, accruals and reserves on the books of the Company in respect of U.S. federal, state or other taxes for all fiscal periods are adequate. The U.S. federal income tax liabilities of the Company have been finally determined
(whether by reason of completed audits or the statute of limitations having run) for all fiscal years up to and including the fiscal year ended December 31, 2007.

 Section 5.10 Title to Property; Leases. The Company has good and sufficient
title to its properties that individually or in the aggregate are Material, including all such properties reflected in the most recent audited balance sheet referred to in Section 5.5 or purported to have been acquired by the Company after said
date (except as sold or otherwise disposed of in the ordinary course of business), in each case free and clear of Liens prohibited by this Agreement. All leases that individually or in the aggregate are Material are valid and subsisting and are in
full force and effect in all material respects. 
 Section 5.11 Licenses, Permits, Etc.The Company owns or possesses
all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that individually or in the aggregate are Material, without known conflict with the rights of
others. 
 (b) To the knowledge of the Company, no product or service of the Company infringes in any material respect any
license, permit, franchise, authorization, patent, copyright, proprietary software, service mark, trademark, trade name or other right owned by any other Person. 
 (c) To the knowledge of the Company, there is no Material violation by any Person of any right of the Company with respect to any patent, copyright, proprietary software, service mark, trademark, trade
name or other right owned or used by the Company. 
 Section 5.12 Compliance with ERISA. (a) The Company and
each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. In
the past six years, neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in section 3
of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any Lien on any of the
rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to section 430(k) of the Code or to any such penalty or excise tax provisions under the Code or Federal law or
section 4068 of ERISA or by the granting of a security interest in connection with the amendment of a Plan, other than such liabilities or Liens as would not be individually or in the aggregate Material. 

(b) The funding target attainment percentage for each of the Plans that is a defined benefit pension plan subject to the minimum funding
standards of section 430 of the Code (as determined for such Plan’s most recently ended plan year on the basis of actuarial assumptions specified for funding purposes under section 430 of the Code) is not less than 80%. For purposes of the
foregoing, the term “funding target attainment percentage” has the meaning specified in section 430(d) of the Code, without regard to any election to maintain funding balances under section 430(f) of the Code. 

(c) The Company and its ERISA Affiliates have not incurred withdrawal liabilities (and are not subject to contingent withdrawal
liabilities) under section 4201 or 4204 of ERISA in respect of Multiemployer Plans that individually or in the aggregate are Material.

 (d) The expected postretirement benefit obligation (determined as of the last day of the
Company’s most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement ASC No. 715, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the

principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if
any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal
amount of any Note. 
 Section 8.6 Purchase of Notes. The Company will not and will not permit any Affiliate to
purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the Notes in accordance with the terms of this Agreement and the Notes or (b) pursuant to an
offer to purchase made by the Company or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each holder with sufficient information to enable it to make an
informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 50.1% of the principal amount of the Notes then outstanding accept such offer, the Company shall promptly notify the
remaining holders of such fact and the expiration date for the acceptance by holders of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 10 Business Days from its receipt of such
notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate pursuant to any payment, prepayment or purchase of Notes pursuant to any provision of this Agreement and no Notes may be issued in
substitution or exchange for any such Notes.

 Section 8.7 Make-Whole Amount. 

“Make-Whole Amount” means, with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of
the Remaining Scheduled Payments with respect to the Called Principal of such Note over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole
Amount, the following terms have the following meanings: 
 “Called Principal” means, with respect to any Note,
the principal of such Note that is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires. 

“Discounted Value” means, with respect to the Called Principal of any Note, the amount obtained by discounting all
Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor
(applied on the same periodic basis as that on which interest on the Notes is payable) equal to the Reinvestment Yield with respect to such Called Principal. 
 “Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the yield(s) reported as of 10:00 a.m. (New York City time) on
the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most
recently issued actively traded on-the-run U.S. Treasury securities (“Reported”) having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury
securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial
practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life
and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. 

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then
“Reinvestment Yield” means, with respect to the Called Principal of any Note, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields, reported, for the latest day for which such yields have been so
reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term
equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by
interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and
less 

  
 - 18 -








 
than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable Note. 

“Remaining Average Life” means, with respect to any Called Principal, the number of years obtained by dividing
(i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the
basis of a 360-day year composed of twelve 30-day months, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. 

“Remaining Scheduled Payments” means, with respect to the Called Principal of any Note, all payments of such Called
Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date, provided that if such Settlement Date is not a
date on which interest payments are due to be made under the terms of the Notes, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on
such Settlement Date pursuant to Section 8.5 or Section 12.1. 
 “Settlement Date” means, with
respect to the Called Principal of any Note, the date on which such Called Principal is to be prepaid pursuant to Section 8.2 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.

referred to in Section 5.16, except in any instances in which any requirement of law or order, writ, injunction or decree is being contested in good faith by appropriate proceedings diligently conducted, and will obtain and maintain in effect
all licenses, certificates, permits, franchises and other governmental authorizations necessary to the ownership of their respective properties or to the conduct of their respective businesses, in each case to the extent necessary to ensure that
non-compliance with such laws, ordinances or governmental rules or regulations or failures to obtain or maintain in effect such licenses, certificates, permits, franchises and other governmental authorizations could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. 
 Section 9.2 Insurance. The Company will, and
will cause each of its Subsidiaries to, maintain, with financially sound and reputable insurers, insurance with respect to their respective properties and businesses against such casualties and contingencies, of such types, on such terms and in such

situated.

required to be filed in any jurisdiction and to pay and discharge all taxes shown to be due and payable on such returns and all other taxes, assessments, governmental charges, or levies imposed on them or any of their properties, assets, income or
franchises, to the extent the same have become due and payable and before they have become delinquent and all claims for which sums have become due and payable that have or might become a Lien on properties or assets of the Company or any
Subsidiary, provided that neither the Company nor any Subsidiary need pay any such tax, assessment, charge, levy or claim if (i) the amount, applicability or validity thereof is contested by the Company or such Subsidiary on a timely
basis in good faith and in appropriate proceedings, and the Company or a Subsidiary has established adequate reserves therefor in accordance with GAAP on the books of the Company or such Subsidiary or (ii) the nonpayment of all such taxes,
assessments, charges, levies and claims in the aggregate could not reasonably be expected to have a Material Adverse Effect. 

Section 9.5 Corporate Existence, Etc. Subject to Section 10.2, the Company will at all times preserve and keep its
corporate existence in full force and effect. Subject to Sections 10.2 and 10.6, the Company will at all times preserve and keep in full force and effect the corporate existence of each of its Subsidiaries (unless merged into the Company or a
Wholly-Owned Subsidiary) and all rights and franchises of the Company and its Subsidiaries unless, in the good faith judgment of the Company, the termination of or failure to preserve and keep in full force and effect such corporate existence, right
or franchise could not, individually or in the aggregate, have a Material Adverse Effect. 
 Section 9.6 Books and
Records. The Company will, and will cause each of its Subsidiaries to, maintain proper books of record and account in conformity with GAAP and all applicable requirements of any Governmental Authority having legal or regulatory jurisdiction over
the Company or such Subsidiary, as the case may be. 
 Section 9.7 Priority of Obligations. The Company will ensure
that its payment obligations under this Agreement and the Notes will at all times rank at least pari passu, without preference or priority, with all other senior unsecured Indebtedness of the Company.

in compliance in all material respects with the applicable provisions of ERISA, the Code and other federal or state law, (ii) cause each Plan that is qualified under Section 401(a) of the Code to maintain such qualification and

required contributions to any Plan subject to Section 412, Section 430 or Section 431 of the Code, except, in each such instance in clause (i), (ii) or (iii) where
the failure to do so would not reasonably be expected to have a Material Adverse Effect. 
 Section 9.9 Investments.
The Company will, and will cause each of its Subsidiaries to, make Investments solely in Persons and/or property which are used or useful in the same or similar line of business as the Company and its Subsidiaries are engaged in as of the date of

If any other Event of Default has occurred and is continuing, any holder or holders of more than 50.1% in principal amount of the Notes at the time outstanding may at any time at its or their option, by notice or notices to the Company, declare all
the Notes then outstanding to be immediately due and payable. 
 (c) If any Event of Default described in Section 11(a) or
(b) has occurred and is continuing, any holder or holders of Notes at the time outstanding affected by such Event of Default may at any time, at its or their option, by notice or notices to the Company, declare all the Notes held by it or them
to be immediately due and payable. 
 Upon any Notes becoming due and payable under this Section 12.1, whether
automatically or by declaration, such Notes will forthwith mature and the entire unpaid principal amount of such Notes, plus (x) all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default
Rate) and (y) the Make-Whole Amount determined in respect of such principal amount (to the full extent permitted by applicable law), shall all be immediately due and payable, in each and every case without presentment, demand, protest or
further notice, all of which are hereby waived. The Company acknowledges, and the parties hereto agree, that each holder of a Note has the right to maintain its investment in the Notes free from repayment by the Company (except as herein
specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the Notes are prepaid or are accelerated as a result of an Event of Default, is intended to provide compensation for the
deprivation of such right under such circumstances. 
 Section 12.2 Other Remedies. If any Default or Event of
Default has occurred and is continuing, and irrespective of whether any Notes have become or have been declared immediately due and payable under Section 12.1, the holder of any Note at the time outstanding may proceed to protect and enforce
the rights of such holder by an action at law, suit in equity or other appropriate proceeding, whether for the specific performance of any agreement contained herein or in any Note, or for an injunction against a violation of any of the terms hereof
or thereof, or in aid of the exercise of any power granted hereby or thereby or by law or otherwise. 
 Section 12.3
Rescission. At any time after any Notes have been declared due and payable pursuant to Section 12.1(b) or (c), the holders of not less than 50.1% in principal amount of the Notes then outstanding, by written notice to the Company, may
rescind and annul any such declaration and its consequences if (a) the Company has paid all overdue interest on the Notes, all principal of and Make-Whole Amount, if any, on any Notes that are due and payable and are unpaid other than by reason
of such declaration, and all interest on such overdue principal and Make-Whole Amount, if any, and (to the extent permitted by applicable law) any overdue interest in respect of the Notes, at the Default Rate, (b) neither the Company nor any
other 

  
 - 28 -








 
Person shall have paid any amounts which have become due solely by reason of such declaration, (c) all Events of Default and Defaults, other than non-payment of amounts that have become due
solely by reason of such declaration, have been cured or have been waived pursuant to Section 17, and (d) no judgment or decree has been entered for the payment of any monies due pursuant hereto or to the Notes. No rescission and annulment
under this Section 12.3 will extend to or affect any subsequent Event of Default or Default or impair any right consequent thereon. 
 Section 12.4 No Waivers or Election of Remedies, Expenses, Etc. No course of dealing and no delay on the part of any holder of any Note in exercising any right, power or remedy shall operate
as a waiver thereof or otherwise prejudice such holder’s rights, powers or remedies. No right, power or remedy conferred by this Agreement or by any Note upon any holder thereof shall be exclusive of any other right, power or remedy referred to
herein or therein or now or hereafter available at law, in equity, by statute or otherwise. Without limiting the obligations of the Company under Section 15, the Company will pay to the holder of each Note on demand such further amount as shall
be sufficient to cover all costs and expenses of such holder incurred in any enforcement or collection under this Section 12, including, without limitation, reasonable attorneys’ fees, expenses and disbursements. 

Section 13. REGISTRATION; EXCHANGE; SUBSTITUTION OF NOTES.

 Section 13.1 Registration of Notes. The Company shall keep at its principal executive office a register for
the registration and registration of transfers of Notes. The name and address of each holder of one or more Notes, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. If any
holder of one or more Notes is a nominee, then the name and address of the beneficial owner of such Note or Notes shall also be registered in such register as an owner and holder thereof. Prior to due presentment for registration of transfer, the
Person(s) in whose name any Note(s) shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary. The Company shall give to
any holder of a Note that is an Institutional Investor promptly upon request therefor, a complete and correct copy of the names and addresses of all registered holders of Notes.

the designated officer (all as specified in Section 18(iii)), for registration of transfer or exchange (and in the case of a surrender for registration of transfer accompanied by a written instrument of transfer duly executed by the registered
holder of such Note or such holder’s attorney duly authorized in writing and accompanied by the relevant name, address and other information for notices of each transferee of such Note or part thereof), within ten Business Days thereafter, the
Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of
the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Note shall be dated and bear interest from the date to which interest
shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect
of any such transfer of Notes. Notes shall not be

(all as specified in Section 18(iii)) of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note (which evidence shall be, in the case of an Institutional Investor, notice from such
Institutional Investor of such ownership and such loss, theft, destruction or mutilation), and 
 (a) in the case of loss, theft
or destruction, of indemnity reasonably satisfactory to it (provided that if the holder of such Note is, or is a nominee for, an original Purchaser or another holder of a Note with a minimum net worth of at least $100,000,000 or a Qualified
Institutional Buyer, such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or 
 (b) in
the case of mutilation, upon surrender and cancellation thereof, 
 within ten Business Days thereafter, the Company at its own expense shall
execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note
if no interest shall have been paid thereon.

and interest becoming due and payable on the Notes shall be made in New York, New York at the principal office of JPMorgan Chase Bank, N.A. in such jurisdiction. The Company may at any time, by notice to each holder of a Note, change the place of
payment of the Notes so long as such place of payment shall be either the principal office of the Company in such jurisdiction or the principal office of a bank or trust company in such jurisdiction. 

Section 14.2 Home Office Payment. So long as any Purchaser or its nominee shall be the holder of any Note, and notwithstanding
anything contained in Section 14.1 or in such Note to the contrary, the Company will pay all sums becoming due on such Note for principal, Make-Whole Amount, if any, interest and all other amounts becoming due hereunder by the method and at the
address specified for such purpose below such Purchaser’s name in Schedule A, or by such other method or at such other address as such Purchaser shall have from time to time specified to the Company in writing for such purpose,
without the presentation or surrender of such Note or the making of any notation thereon, except that upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, such Purchaser
shall surrender such Note for cancellation, reasonably promptly after any such request, to the Company at its principal executive office or at the place of payment most recently designated by the Company pursuant to Section 14.1. Prior to any
sale or other disposition of any Note held by a Purchaser or its nominee, such Purchaser will, at its election, 

  
 - 30 -








 
either endorse thereon the amount of principal paid thereon and the last date to which interest has been paid thereon or surrender such Note to the Company in exchange for a new Note or Notes
pursuant to Section 13.2. The Company will afford the benefits of this Section 14.2 to any Institutional Investor that is the direct or indirect transferee of any Note purchased by a Purchaser under this Agreement and that has made the
same agreement relating to such Note as the Purchasers have made in this Section 14.2. 
 Section 15. EXPENSES,
ETC. 
 Section 15.1 Transaction Expenses. Whether or not the transactions contemplated hereby are
consummated, the Company will pay all costs and expenses (including reasonable attorneys’ fees of a special counsel and, if reasonably required by the Required Holders, local or other counsel) incurred by the Purchasers and each other holder of
a Note in connection with such transactions and in connection with any amendments, waivers or consents under or in respect of this Agreement or the Notes (whether or not such amendment, waiver or consent becomes effective), including, without
limitation: (a) the costs and expenses incurred in enforcing or defending (or determining whether or how to enforce or defend) any rights under this Agreement or the Notes or in responding to any subpoena or other legal process or informal

Agreement and all related documents and financial information with the SVO, provided, that such costs and expenses under this clause (c) shall not exceed $3,500.

Agreement or the Notes, and the termination of this Agreement. 
 Section 16. SURVIVAL OF
REPRESENTATIONS AND WARRANTIES; ENTIRE AGREEMENT. 

All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the Notes, the purchase
or transfer by any Purchaser of any Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent holder of a Note, regardless of any investigation made at any time by or on behalf of such
Purchaser or any other holder of a Note. All statements contained in any certificate or other instrument delivered by or on behalf of the Company pursuant to this Agreement shall be deemed representations and warranties of the Company under this
Agreement. Subject to the preceding sentence, this Agreement and the Notes embody the entire agreement and understanding between each Purchaser and the Company and supersede all prior agreements and understandings relating to the subject matter
hereof. 
 Section 17. AMENDMENT AND WAIVER. 

Section 17.1 Requirements. This Agreement and the Notes may be amended, and the observance of any term hereof or of the Notes may
be waived (either retroactively or 

  
 - 31 -








 
prospectively), only with the written consent of the Company and the Required Holders, except that: 
 (a) no amendment or waiver of any of the provisions of Section 1, 2, 3, 4, 5, 6 or 21 hereof, or any defined term (as it is used therein), will be effective as to any Purchaser unless consented to by
such Purchaser in writing; and 
 (b) no such amendment or waiver may, without the written consent of the holder of each Note at
the time outstanding, (i) subject to the provisions of Section 12 relating to acceleration or rescission, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of
computation of (x) interest on the Notes or (y) the Make-Whole Amount, (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any amendment or waiver, or (iii) amend any of
Sections 8, 11(a), 11(b), 12, 17 or 20. 
 Section 17.2 Solicitation of Holders of Notes. 

(a) Solicitation. The Company will provide each holder of a Note with sufficient information, sufficiently far in advance of the
date a decision is required, to enable such holder to make an informed and considered decision with respect to any proposed amendment, waiver or consent in respect of any of the provisions hereof or of the Notes. The Company will deliver executed or
true and correct copies of each amendment, waiver or consent effected pursuant to the provisions of this Section 17 to each holder of outstanding Notes promptly following the date on which it is executed and delivered by, or receives the
consent or approval of, the requisite holders of Notes. 
 (b) Payment. The Company will not directly or indirectly pay or
cause to be paid any remuneration, whether by way of supplemental or additional interest, fee or otherwise, or grant any security or provide other credit support, to any holder of a Note as consideration for or as an inducement to the entering into
by any such holder of any waiver or amendment of any of the terms and provisions hereof or any Note unless such remuneration is concurrently paid, or security is concurrently granted or other credit support concurrently provided, on the same terms,
ratably to each holder of a Note then outstanding even if such holder did not consent to such waiver or amendment. 
 (c)
Consent in Contemplation of Transfer. Any consent made pursuant to this Section 17 by a holder of Notes that has transferred or has agreed to transfer its Notes to the Company, any Subsidiary or any Affiliate of the Company pursuant to
Section 8.6 and has provided or has agreed to provide such written consent as a condition to such transfer shall be void and of no force or effect except solely as to such holder, and any amendments effected or waivers granted or to be effected
or granted that would not have been or would not be so effected or granted but for such consent (and the consents of all other holders of Notes that were acquired under the same or similar conditions) shall be void and of no force and effect except
solely as to such holder. 
 Section 17.3 Binding Effect, Etc. Any amendment or waiver consented to as
provided in this Section 17 applies equally to all holders of Notes and is binding upon them and upon each 

  
 - 32 -








 
future holder of any Note and upon the Company without regard to whether such Note has been marked to indicate such amendment or waiver. No such amendment or waiver will extend to or affect any
obligation, covenant, agreement, Default or Event of Default not expressly amended or waived or impair any right consequent thereon. No course of dealing between the Company and the holder of any Note nor any delay in exercising any rights hereunder
or under any Note shall operate as a waiver of any rights of any holder of such Note. 
 Section 17.4 Notes Held by
Company, Etc. Solely for the purpose of determining whether the holders of the requisite percentage of the aggregate principal amount of Notes then outstanding approved or consented to any amendment, waiver or consent to be given under this
Agreement or the Notes, or have directed the taking of any action provided herein or in the Notes to be taken upon the direction of the holders of a specified percentage of the aggregate principal amount of Notes then outstanding, Notes directly or
indirectly owned by the Company or any of its Affiliates shall be deemed not to be outstanding. 
 Section 18. NOTICES.

 All notices and communications provided for hereunder shall be in writing and sent (a) by telecopy if the sender on
the same day sends a confirming copy of such notice by an internationally recognized overnight delivery service (charges prepaid), or (b) by registered or certified mail with return receipt requested (postage prepaid), or (c) by an
internationally recognized overnight delivery service (with charges prepaid). Any such notice must be sent: 

(i) if to any Purchaser or its nominee, to such Purchaser or nominee at the address specified for such communications in
Schedule A, or at such other address as such Purchaser or nominee shall have specified to the Company in writing, 
 (ii) if to any other holder of any Note, to such holder at such address as such other holder shall have specified to the Company in writing, or 

(iii) if to the Company, to the Company at its address set forth on its signature page hereto to the attention of the
Treasurer, or at such other address as the Company shall have specified to the holder of each Note in writing. 
 Notices under this
Section 18 will be deemed given only when actually received. 
 Section 19. REPRODUCTION OF
DOCUMENTS. 
 This Agreement and all documents relating thereto, including, without limitation,
(a) consents, waivers and modifications that may hereafter be executed, (b) documents received by any party at the Closing (except the Notes themselves), and (c) financial statements, certificates and other information previously or
hereafter furnished to any party, may be reproduced by such party by any photographic, photostatic, electronic, digital, or other similar process and such party may destroy any original document so reproduced. The Company and each Purchaser agree
and stipulate that, to the extent permitted by applicable law, any such reproduction shall be admissible in evidence as the original itself in any judicial or administrative proceeding (whether or not the original is in existence and whether or not
such reproduction was made by any party to this Agreement in the regular course of business) and any enlargement, 

  
 - 33 -








 
facsimile or further reproduction of such reproduction shall likewise be admissible in evidence. This Section 19 shall not prohibit the Company, any Purchaser or any other holder of Notes
from contesting any such reproduction to the same extent that it could contest the original, or from introducing evidence to demonstrate the inaccuracy of any such reproduction. 
 Section 20. CONFIDENTIAL INFORMATION. 

For the purposes of this Section 20, “Confidential Information” means information delivered to any Purchaser by or on
behalf of the Company or any Subsidiary in connection with the transactions contemplated by or otherwise pursuant to this Agreement that is proprietary in nature and that was clearly marked or labeled or otherwise adequately identified when received
by such Purchaser as being confidential information of the Company or such Subsidiary, provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such
disclosure, (b) subsequently becomes publicly known through no act or omission by such Purchaser or any Person acting on such Purchaser’s behalf, (c) otherwise becomes known to such Purchaser other than through disclosure by the
Company or any Subsidiary or (d) constitutes financial statements delivered to such Purchaser under Section 7.1 that are otherwise publicly available. Each Purchaser will maintain the confidentiality of such Confidential Information in
accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its
directors, officers, employees, agents, attorneys, trustees and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by its Notes), (ii) its auditors, financial advisors and other
professional advisors who agree to hold confidential the Confidential Information substantially in accordance with the terms of this Section 20, (iii) any other holder of any Note, (iv) any Institutional Investor to which it sells or
offers to sell such Note or any part thereof or any participation therein (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (v) any Person from
which it offers to purchase any Security of the Company (if such Person has agreed in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 20), (vi) any federal or state regulatory
authority having jurisdiction over such Purchaser, (vii) the NAIC or the SVO or, in each case, any similar organization, or any nationally recognized rating agency that requires access to information about such Purchaser’s investment
portfolio, or (viii) any other Person to which such delivery or disclosure may be necessary or appropriate (w) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (x) in response to any subpoena
or other legal process, (y) in connection with any litigation to which such Purchaser is a party or (z) if an Event of Default has occurred and is continuing, to the extent such Purchaser may reasonably determine such delivery and
disclosure to be necessary or appropriate in the enforcement or for the protection of the rights and remedies under such Purchaser’s Notes and this Agreement. Each holder of a Note, by its acceptance of a Note, will be deemed to have agreed to
be bound by and to be entitled to the benefits of this Section 20 as though it were a party to this Agreement. On reasonable request by the Company in connection with the delivery to any holder of a Note of information required to be delivered
to such holder under this Agreement or requested by such holder (other than a holder that is a party to this Agreement or its nominee), such holder will enter into an agreement with the Company embodying the provisions of this Section 20.


  
 - 34 -








 In the event that as a condition to receiving access to information relating to the Company
or its Subsidiaries in connection with the transactions contemplated by or otherwise pursuant to this Agreement, any Purchaser is required to agree to a confidentiality undertaking (whether through Intralinks or otherwise) which is different from
the terms of this Section 20, the terms of this Section 20 shall, as between such Purchaser and the Company, supersede the terms of any such other confidentiality undertaking. 
 Section 21. SUBSTITUTION OF PURCHASER. 
 Each Purchaser shall have the right to substitute any one of its Affiliates as the purchaser of the Notes that it has agreed to purchase hereunder, by written notice to the Company, which notice shall be
signed by both such Purchaser and such Affiliate, shall contain such Affiliate’s agreement to be bound by this Agreement and shall contain a confirmation by such Affiliate of the accuracy with respect to it of the representations set forth in
Section 6. Upon receipt of such notice, any reference to such Purchaser in this Agreement (other than in this Section 21), shall be deemed to refer to such Affiliate in lieu of such original Purchaser. In the event that such Affiliate is
so substituted as a Purchaser hereunder and such Affiliate thereafter transfers to such original Purchaser all of the Notes then held by such Affiliate, upon receipt by the Company of notice of such transfer, any reference to such Affiliate as a
“Purchaser” in this Agreement (other than in this Section 21), shall no longer be deemed to refer to such Affiliate, but shall refer to such original Purchaser, and such original Purchaser shall again have all the rights of an
original holder of the Notes under this Agreement. 
 Section 22. MISCELLANEOUS. 

Section 22.1 Successors and Assigns. All covenants and other agreements contained in this Agreement by or on behalf of any of
the parties hereto bind and inure to the benefit of their respective successors and assigns (including, without limitation, any subsequent holder of a Note) whether so expressed or not. 

Section 22.2 Payments Due on Non-Business Days. Anything in this Agreement or the Notes to the contrary notwithstanding (but
without limiting the requirement in Section 8.5 that the notice of any optional prepayment specify a Business Day as the date fixed for such prepayment), any payment of principal of or Make-Whole Amount or interest on any Note that is due on a
date other than a Business Day shall be made on the next succeeding Business Day without including the additional days elapsed in the computation of the interest payable on such next succeeding Business Day; provided that if the maturity date
of any Note is a date other than a Business Day, the payment otherwise due on such maturity date shall be made on the next succeeding Business Day and shall include the additional days elapsed in the computation of interest payable on such next
succeeding Business Day. 
 Section 22.3 Accounting Terms. (a) All accounting terms used herein which are not expressly
defined in this Agreement have the meanings respectively given to them in accordance with GAAP. Except as otherwise specifically provided herein, (i) all computations made pursuant to this Agreement shall be made in accordance with GAAP, and
(ii) all financial statements shall be prepared in accordance with GAAP. For purposes of determining compliance with the financial covenants contained in this Agreement, any election by the


  
 - 35 -








 
Company to measure any financial liability using fair value (as permitted by Accounting Standard Codification Topic No. 825-10-25 – Fair Value Option or any similar accounting standard)
shall be disregarded and such determination shall be made as if such election had not been made. 
 (b) If at any time any change
in GAAP would affect the computation of any financial ratio or requirement set forth herein, and either the Company or the Required Holders shall so request, the Company and the Purchasers shall negotiate in good faith to amend such ratio or
requirement to preserve the original intent thereof in light of such change in GAAP (subject to the approval of the Required Holders); provided that, until so amended, (i) such ratio or requirement shall continue to be computed in
accordance with GAAP prior to such change therein and (ii) the Company shall provide to the Purchasers financial statements and other documents required under this Agreement or as reasonably requested hereunder setting forth a reconciliation
between calculations of such ratio or requirement made before and after giving effect to such change in GAAP. 
 (c)
Notwithstanding the above, the parties hereto acknowledge and agree that all calculations of the financial covenant set forth in Section 10.10 shall be made on a Pro Forma Basis with respect to any Disposition (other than any Permitted
Transfer), Acquisition or incurrence of Indebtedness occurring during the applicable period. 
 (d) If at any time, as a result
of any change in generally accepted auditing standards, it becomes customary or acceptable with respect to the audits of the financial statements of entities in the same or similar line of business as the Company for there to be qualifications or
exceptions as to the scope of the audits of such entities, and if either the Company or any Purchaser shall so request, the Purchasers and the Company shall negotiate in good faith to amend the requirements of Section 7.1 with respect to the
scope of the audit of the financial statements of the Company and the form and substance of the opinion of the independent certified public accountant with respect thereto so as to provide for an audit and opinion to be prepared in light of such
changes to generally accepted auditing standards, subject to the approval of the Purchasers. 
 Section 22.4
Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall (to the full extent permitted by law) not invalidate or render unenforceable such provision in any other jurisdiction. 

Section 22.5 Construction, Etc. Each covenant contained herein shall be construed (absent express provision to the contrary)
as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to
action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. 

  
 - 36 -








 For the avoidance of doubt, all Schedules and Exhibits attached to this Agreement shall be
deemed to be a part hereof. 
 Section 22.6 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original but all of which together shall constitute one instrument. Each counterpart may consist of a number of copies hereof, each signed by less than all, but together signed by all, of the parties hereto.

 Section 22.7 Governing Law. This Agreement shall be construed and enforced in accordance with, and the rights of
the parties shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a jurisdiction other than such State. 

Section 22.8 Jurisdiction and Process; Waiver of Jury Trial. (a) The Company and each Purchaser irrevocably submit to
the exclusive jurisdiction of any New York State or federal court sitting in the Borough of Manhattan, The City of New York (the “New York Court”), over any suit, action or proceeding arising out of or relating to this Agreement or
the Notes. To the fullest extent permitted by applicable law, the Company and each Purchaser irrevocably waive and agree not to assert, by way of motion, as a defense or otherwise, any claim that it is not subject to the jurisdiction of any such
court, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in
an inconvenient forum; provided that such waiver and agreement shall not preclude the Company or any Purchaser from seeking the removal of such suit, action or proceeding from state court to federal court. The foregoing notwithstanding, if
the New York Court does not accept jurisdiction, the suit, action, or proceeding may be brought in another forum. 
 (b) Nothing
in this Section 22.8 shall limit any right that the holders of any of the Notes may have to bring proceedings against the Company to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 

(c) The parties hereto hereby waive trial by jury in any action brought on or with respect to this Agreement, the Notes or any other
document executed in connection herewith or therewith. 
 Section 22.9 Publication. (a) Neither the Company nor
any of its Subsidiaries or Affiliates shall use the name or logo “AIG”, “AMG”, “AIG Asset Management Group”, “AIG Asset Management (U.S.), LLC”, “CAF”, “AIG Commercial Equipment Finance,
Inc.”, “AIG Commercial Asset Finance”, “AIG Commercial Equipment Finance, Inc. d/b/a AIG Commercial Asset Finance” or any derivative of the foregoing in any press release or similar public disclosure (including in any
marketing material) without the prior written approval of AIG Asset Management (U.S.), LLC; provided, however, that the Company and its Subsidiaries and Affiliates may reference the names listed above in any filing required to be made
pursuant to applicable securities laws to the extent required by such laws. 

  
 - 37 -








 (b) The Company agrees that AIG Asset Management (U.S.), LLC and/or AIG Commercial Equipment
Finance, Inc. d/b/a AIG Commercial Asset Finance may (i) refer to its role in originating the purchase of the Notes from the Company, as well as the identity of the Company, the aggregate principal amount of the Notes and issue date of the
Notes, on its internet site or in marketing materials, press releases, published “tombstone” announcements or any other print or electronic medium and (ii) display the Company’s corporate logo in conjunction with any such
reference.
