The Fund is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, and is duly qualified as a foreign corporation and is in good standing in each 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 would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Fund 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 the Financing Agreements and to perform the provisions hereof and thereof. The Fund is a non-diversified, closed-end management investment company as such term is used in the 1940 Act.

Section 5.2. Authorization, Etc. The Financing Agreements have been duly authorized by all necessary corporate action on the part of the Fund, and the Financing Agreements (other than the Notes) constitute, and upon execution and delivery thereof each Note will constitute, a legal, valid and binding obligation of the Fund enforceable against the Fund 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. The Fund, through its agent, Xxxxxx Xxxxxxx & Co. LLC, has delivered to each Purchaser a copy of the Memorandum relating to the transactions contemplated hereby.

The Fund does not have any Material liabilities that are not disclosed on such financial statements or otherwise disclosed in the Disclosure Documents or identified in Schedule 5.15.

Section 5.6. Compliance with Laws, Other Instruments, Etc. The execution, delivery and performance by the Fund of the Financing Agreements will not (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 Fund under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, corporate charter or by-laws, or any other Material agreement or instrument to which the Fund is bound or by which the Fund or any of its properties may be bound or affected, except for (A) the Lien in favor of the Note Agent contemplated hereby and, (B) with respect to the Custody Agreement, the Control Agreement and the Intercreditor Agreement, the Liens created or contemplated thereby constituting Permitted Liens described in clauses (ii) and (iv) of the definition of “Permitted Liens”, (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 Fund or (iii) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Fund, including, without limitation, the Securities Act and the 1940 Act, except where such contravention, conflict, breach, or violation would not reasonably be likely to have a Material Adverse Effect.

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 Fund of the Financing Agreements, except such as has been made or obtained or with respect to which the failure to make or obtain would not reasonably be likely to have a Material Adverse Effect.

Section 5.8. Litigation; Observance of Statutes and Orders. (a) There are no actions, suits, investigations or proceedings pending or, to the knowledge of the Fund, threatened against or affecting the Fund or any property of the Fund in any court or before any arbitrator of any kind or before or by any Governmental Authority that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect.

-7-


ClearBridge Energy MLP Opportunity Fund Inc.		Note Purchase Agreement

(b) The Fund is not in default under any order, judgment, decree or ruling of any court, arbitrator or Governmental Authority and is not in violation of any applicable law, ordinance, rule or regulation (including without limitation Environmental Laws or the USA Patriot Act) of any Governmental Authority, which default or violation, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect.

Section 5.9. Taxes. The Fund has filed all income 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 payable by them, to the extent such taxes and assessments have become due and payable and before they have become delinquent, except for (i) the failure to file any such tax returns or the nonpayment of any such taxes and assessments which would not individually or in the aggregate be reasonably expected to have a Material Adverse Effect or (ii) the nonpayment of any such taxes or assessments, the amount, applicability or validity of which is currently being contested in good faith by appropriate proceedings and with respect to which the Fund has established adequate reserves in accordance with GAAP. The Federal income tax liability of the Fund has 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 November 30, 2012.

Section 5.10. Title to Property; Leases. (a) The Issuer has good and marketable title to all properties, assets and rights, except where failure to have such title would not reasonably be expected to have a Material Adverse Effect. The Fund neither owns nor leases any real property. As of the date hereof, none of the Fund’s property is subject to any Lien, other than Permitted Liens.

(b) The Security Agreement creates a first priority Lien upon the Collateral (subject to Permitted Liens described in clauses (iii) through (v) of the definition thereof and pari passu with Xxxxx described as pari passu in clause (ii) thereof) and the Fund has not assigned, pledged, sold or otherwise conveyed any interest in the Collateral which remains in effect on the date of Closing to any Person other than pursuant to (i) the Security Agreement, (ii) any security agreement executed pursuant to the Bank Facility (and subject to intercreditor arrangements with the Note Agent) and (iii) any Permitted Lien.

Section 5.11. Licenses, Permits, Etc. The Fund owns or possesses all licenses, permits, franchises, authorizations, patents, copyrights, proprietary software, service marks, trademarks and trade names, or rights thereto, that are Material, without known conflict with the rights of others, except for those conflicts that, individually or in the aggregate, would not have a Material Adverse Effect.

Section 5.12. Compliance with ERISA. Neither the Fund nor any ERISA Affiliate maintains, contributes to or is obligated to maintain or contribute to, or has, at any time in the past six years, maintained, contributed to or been obligated to maintain or contribute to, any employee benefit plan which is subject to Title I or Title IV of ERISA or Section 4975 of the Code.

-8-


ClearBridge Energy MLP Opportunity Fund Inc.		Note Purchase Agreement

section 3(14) of ERISA) or a “disqualified person” (as defined in Section 4975 of the Code) with respect to any such plan.

Section 5.13. Private Offering by the Fund. Neither the Fund nor anyone acting on its behalf has offered the Notes or any similar securities for sale to, or solicited any offer to buy any of the same from, or otherwise approached or negotiated in respect thereof with, more than 80 Persons, all of which were Institutional Investors, including the Purchasers, each of which has been offered the Notes or similar securities at a private sale for investment. Neither the Fund nor anyone acting on its behalf has taken, or will take, any action that would subject the issuance or sale of the Notes to the registration requirements of Section 5 of the Securities Act or to the registration requirements of any securities or blue sky laws of any applicable jurisdiction.

Section 5.14. Use of Proceeds; Margin Regulations. The Fund will apply the proceeds of the sale of the Notes as permitted under the 1940 Act including for the refinancing of existing Indebtedness, making new portfolio investments and for general corporate purposes.

The Fund will give each holder of the Notes written notice of each optional prepayment under this Section 8.2.1 not less than 12 days (or 7 days in the case of any notice of prepayment in connection with a prepayment to cure any default under Sections 9.7(a) or 9.7(b), or both) and not more than 75 days prior to the date fixed for such prepayment.

Section 8.5. Purchase of Notes. The Fund 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 Fund or an Affiliate pro rata to the holders of all of the Notes at the time outstanding upon the same terms and conditions with respect to the Notes. 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 20 Business Days. If the holders of more than 50% of the principal amount of the Notes, then outstanding accept such offer, the Fund 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 Fund 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 8.6. Make-Whole Amount. “Make-Whole Amount” means (except as specified in Sections 8.2.2 and 8.2.4) with respect to any Note, an amount equal to the excess, if any, of the Discounted Value of the Remaining

-20-


ClearBridge Energy MLP Opportunity Fund Inc.		Note Purchase Agreement

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 8.2.1 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, .50% (50 basis points) over the yield to maturity implied by (i) the yields 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 having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of interpolation), the Treasury Constant Maturity Series 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 U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

In the case of each determination under clause (i) or clause (ii), as the case may be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between (1) the applicable U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable U.S. Treasury security with the maturity 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.

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest one-twelfth year) 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 (calculated to the nearest one-twelfth year) that will elapse

-21-


ClearBridge Energy MLP Opportunity Fund Inc.		Note Purchase Agreement

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 such Note, 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 8.2.1 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 8.2.1 or has become or is declared to be immediately due and payable pursuant to Section 12.1, as the context requires.
