SUMMARY TERM SHEET

This Summary Term Sheet highlights certain information concerning this Offer. To understand the Offer (as defined below) fully and for a more complete discussion of the terms and conditions of this Offer, you should read carefully this entire Offer to Purchase and the related Letter of Transmittal.

What is the Offer?

Western Asset Investment Grade Defined Opportunity Trust Inc. is offering to purchase up to 100% of its outstanding Shares, or 10,848,022 Shares, for cash at a price per share equal to 100% of the per share net asset value as of the close of the regular trading session (normally 5:00 p.m. New York City time) on the New York Stock Exchange (“NYSE”) on October 1, 2024 (or if the Offer is extended, on the next trading day after the day to which the Offer is extended), upon specified terms and subject to conditions as set forth in the Offer documents. Following the Offer, if less than $50 million of net assets remain in the Fund, the Offer will be cancelled and the Fund will liquidate on or about December 2, 2024.

Are there conditions to the Offer?

The Offer is subject to certain conditions as described in Section 13 of this Offer to Purchase. Additionally, following the Offer, if less than $50 million of net assets remain in the Fund, the Offer will be cancelled and the Fund will liquidate on or about December 2, 2024.

When will the Offer expire, and may the Offer be extended?

The Offer will expire at 5:00 p.m., New York City time, on October 1, 2024, unless extended. The Fund may extend the period of time the Offer will be open by issuing a press release or making some other public announcement by no later than the next business day after the Offer otherwise would have expired. See Section 1 of this Offer to Purchase.

What is the net asset value per Fund Share as of a recent date?

As of August 12, 2024, the net asset value per share was $17.75. See Section 7 of this Offer to Purchase for additional information regarding net asset values and market prices. As of August 12, 2024, there were 10,848,022 Shares issued and outstanding. During the pendency of the Offer, current net asset value quotations can be obtained from the Information Agent by calling toll free at (866) 461-7052 between 9:00 a.m. and 9:00 p.m., New York City time, Monday through Friday. You may also call the Fund’s toll free number at (888) 777-0102.

Will the net asset value be higher or lower on the date that the price to be paid for tendered Shares is to be determined?

No one can accurately predict the net asset value at a future date, but you should realize that net asset value on the date the purchase price for tendered Shares is to be determined may be higher or lower than the net asset value on August 12, 2024.

How do I tender my Shares?

If your Shares are registered in your name, you should obtain the tender offer materials, including this Offer to Purchase and the related Letter of Transmittal, read them, and if you should decide to tender, complete a Letter of Transmittal and submit any other documents required by the Letter of Transmittal. These materials must be received by the Depositary in proper form before 5:00 p.m., New York City time, on October 1, 2024 (unless the Offer has been extended by the Fund, in which case the new deadline will be as stated in the public announcement of the extension). If your Shares are held by a broker, dealer, commercial bank, trust company or other nominee (e.g., in “street name”), you should contact that firm to obtain the package of information necessary to make your decision, and you can only tender your Shares by directing that firm to complete, compile and deliver the necessary documents for submission to the Depositary by 5:00 p.m., New York City time, on October 1, 2024 (or if the Offer is extended, the expiration date as extended). If you are an institution participating in the book-entry transfer facility, you must tender your Shares according to the procedure for book-entry transfer. See Section 3 of this Offer to Purchase.

4

Is there any cost to me to tender?

No fees or commission will be payable to the Fund in connection with the Offer. However, brokers, dealers or other persons may charge stockholders a fee for soliciting tenders for Shares pursuant to this Offer. See the Letter of Transmittal.

May I withdraw my Shares after I have tendered them and, if so, by when?

Yes, you may withdraw your Shares at any time prior to 5:00 p.m., New York City time on October 1, 2024 (or if the Offer is extended, at any time prior to 5:00 p.m., New York City time, on the new expiration date). Withdrawn Shares may be re-tendered by following the tender procedures before the Offer expires (including any extension period). See Section 4 of this Offer to Purchase.

How do I withdraw previously tendered Shares?

A notice of withdrawal of tendered Shares must be timely received by the Depositary, and must specify the name of the Stockholder who tendered the shares, the number of Shares being withdrawn (which must be all of the Shares tendered) and, with respect to share certificates representing tendered Shares that have been delivered or otherwise identified to the Depositary, the name of the registered owner of such Shares if different from the person who tendered the Shares. See Section 4 of this Offer to Purchase.

May I place any condition on my tender of Shares?

No.

Is there a limit on the number of Shares I may tender?

No. Following the Offer, if less than $50 million of net assets remain in the Fund, the Offer will be cancelled and the Fund will liquidate on or about December 2, 2024.

Must I tender all of my Shares for repurchase?

No. You may tender for repurchase all or part of the Shares you own.

If I decline to tender, how will the tender offer affect the Shares I hold?

Your percentage ownership interest in the Fund will increase after completion of the tender offer.

How will the Fund pay for the Offer?

It is anticipated that the Fund will increase its use of leverage, sell certain portfolio securities and/or use cash on hand to finance the Offer.

If Shares I tender are accepted by the Fund, when will payment be made?

Payment for tendered Shares, if accepted, will be made promptly after the termination date of the Offer.

Is my sale of Shares in the Offer a taxable transaction for U.S. federal income tax purposes?

For most Stockholders, yes. The sale of Shares pursuant to the Offer by a U.S. Stockholder (as defined in Section 8), other than one who is tax-exempt, will be a taxable transaction for U.S. federal income tax purposes, either as a sale or exchange, or, under certain circumstances, as a distribution with respect to such Shares. An applicable

5

withholding agent may withhold U.S. federal income taxes equal to 30% of the gross proceeds payable to a Non-U.S. Stockholder (as defined in Section 8) unless the agent determines that such Non-U.S. Stockholder is eligible for a reduced rate of withholding pursuant to a treaty or that an exemption from withholding is applicable because the gross proceeds are effectively connected with the Non-U.S. Stockholder’s conduct of a trade or business within the U.S. (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Stockholder). See Section 8 of this Offer to Purchase for a more detailed discussion of certain U.S. federal income tax consequences of the Offer. Stockholders are advised to consult their own tax advisors.

Is the Fund required to complete the Offer and purchase all Shares tendered up to the maximum of 10,848,022 Shares?

Under most circumstances, yes. There are certain circumstances, however, in which the Fund will not be required to purchase any Shares tendered as described in Section 13 of this Offer to Purchase.

Is there any reason Shares tendered will not be accepted?

In addition to those circumstances described in Section 13 of this Offer to Purchase in which the Fund is not required to accept tendered Shares, the Fund has reserved the right to reject any and all tenders determined by it not to be in appropriate form. For example, tenders will be rejected if the tender does not include the original signature(s) or the original of any required signature guarantee(s).

How will tendered Shares be accepted for payment?

Properly tendered Shares, up to the number tendered for, will be accepted for payment by a determination of the Fund followed by notice of acceptance to the Depositary, which thereafter will make payment as directed by the Fund with funds to be deposited with it by the Fund. See Section 2 of this Offer to Purchase.

What action need I take if I decide not to tender my Shares?

None.

What is the purpose of the Offer?

The Offer is intended to provide Stockholders with an alternative source of liquidity for their Shares and, potentially, to reduce the discount to net asset value at which the Shares trade. In approving the Offer, the Board considered a number of factors, including: the economic condition of the investment markets; that the Offer could provide liquidity for Stockholders; that the Offer could enable Stockholders to tender a portion of their Shares at a price that is greater than what they could realize in the secondary market at that time; that the Offer may assist in narrowing the discount to net asset value at which the Shares trade; and that the Investment Manager recommended the Offer to the Board. The Board also considered the potential impact of the Offer on the Fund’s ability to implement its investment strategies, and achieve its investment objective. After considering the totality of the factors listed in this paragraph and other factors, none of which standing on its own was dispositive, the Board determined to authorize this Offer. There is no guarantee that the Offer will be accretive to the Fund’s net asset value.

Please bear in mind that none of the Fund, its Board of Directors, the Investment Manager or the Subadvisers makes any recommendation as to whether or not you should tender your Shares. Stockholders are urged to consult their own investment and tax advisors and make their own decisions whether to tender any Shares and, if so, how many Shares to tender. The Fund has been advised that no director or officer of the Fund intends to tender Shares.

6

How do I obtain additional information?

Questions and requests for assistance should be directed to the Information Agent for the Offer, toll free at (866) 461-7052. Requests for additional copies of the Offer to Purchase, the Letter of Transmittal and all other tender offer documents should also be directed to the Information Agent for the Offer. If you do not hold certificates for your Shares or if you are not the record holder of your Shares, you should obtain this information and the documents from your broker, dealer, commercial bank, trust company or other nominee, as appropriate.

TO THE STOCKHOLDERS OF SHARES OF COMMON STOCK OF WESTERN ASSET INVESTMENT

GRADE DEFINED OPPORTUNITY TRUST INC.

INTRODUCTION

Western Asset Investment Grade Defined Opportunity Trust Inc. (the “Fund”), a Maryland corporation registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a closed-end, non-diversified management investment company, hereby offers to purchase up to 100% of the Fund’s outstanding shares of common stock or 10,848,022 shares in the aggregate (the “Offer Amount”) of its common stock, par value $0.001 per share (the “Shares”), at a price (the “Purchase Price”) per Share, net to the seller in cash, equal to 100% of the net asset value in U.S. Dollars (“NAV”) per Share as of the close of regular trading session on the NYSE on October 1, 2024, or, if the Offer is extended, on the next trading day after the day to which the Offer is extended, upon the terms and subject to the conditions set forth in this Offer to Purchase and in the related Letter of Transmittal (which together constitute the “Offer”). The depositary for the Offer is Computershare Inc. and its wholly owned subsidiary, Computershare Trust Company, N.A. (the “Depositary”). The Fund has mailed materials for the Offer to record holders on or about September 3, 2024.

THIS OFFER IS BEING EXTENDED TO ALL STOCKHOLDERS OF THE FUND AND IS NOT CONDITIONED ON ANY MINIMUM NUMBER OF SHARES BEING TENDERED, BUT IS SUBJECT TO OTHER CONDITIONS AS OUTLINED HEREIN AND IN THE LETTER OF TRANSMITTAL. SEE SECTION 13 OF THIS OFFER TO PURCHASE.

NONE OF THE FUND, ITS BOARD OF DIRECTORS, FRANKLIN TEMPLETON FUND ADVISER, LLC (FORMERLY KNOWN AS LEGG MASON PARTNERS FUND ADVISOR, LLC) (THE “INVESTMENT MANAGER”), WESTERN ASSET MANAGEMENT COMPANY, LLC, WESTERN ASSET MANAGEMENT COMPANY PTE. LTD., WESTERN ASSET MANAGEMENT COMPANY LTD AND WESTERN ASSET MANAGEMENT COMPANY LIMITED (THE “SUBADVISERS”), MAKES ANY RECOMMENDATION AS TO WHETHER TO TENDER OR NOT TO TENDER SHARES IN THE OFFER. NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR TO MAKE ANY REPRESENTATIONS IN CONNECTION WITH THE OFFER OTHER THAN THOSE CONTAINED HEREIN AND IN THE LETTER OF TRANSMITTAL, AND IF GIVEN OR MADE, SUCH INFORMATION OR REPRESENTATIONS MAY NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED BY THE FUND. THE FUND HAS BEEN ADVISED THAT NO DIRECTOR OR OFFICER OF THE FUND INTENDS TO TENDER ANY SHARES PURSUANT TO THE OFFER.

THIS TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED ON THE FAIRNESS OR MERITS OF SUCH TRANSACTION OR ON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

BECAUSE THIS OFFER IS LIMITED AS TO THE NUMBER OF SHARES ELIGIBLE TO PARTICIPATE, NOT ALL SHARES TENDERED FOR PURCHASE BY STOCKHOLDERS MAY BE ACCEPTED FOR PURCHASE BY THE FUND. THIS MAY OCCUR, FOR EXAMPLE, WHEN ONE OR MORE LARGE INVESTORS SEEK TO TENDER A SIGNIFICANT NUMBER OF SHARES OR WHEN A LARGE NUMBER OF INVESTORS TENDER THEIR SHARES IN THIS OFFER.

As of August 12, 2024, there were 10,848,022 Shares issued and outstanding, and the NAV was $17.75 per Share. The Fund does not expect that the number of Shares issued and outstanding will be materially different on the Termination Date (as defined below). Stockholders may contact Georgeson LLC, the Fund’s Information Agent, toll free at (866) 461-7052 or contact the Fund directly at its toll free number, (888) 777-0102, to obtain the estimated current NAV for the Shares.

Any Shares acquired by the Fund pursuant to the Offer will become authorized but unissued shares and will be available for issuance by the Fund without further Stockholder action (except as required by applicable law). Tendering Stockholders may be obligated to pay brokerage fees or commissions or, subject to Instruction 6 of the Letter of Transmittal, transfer taxes on the purchase of Shares by the Fund. Stockholders may also be subject to other transaction costs, as described in Section 1.

1. Terms of the Offer; Termination Date

Upon the terms and subject to the conditions set forth in the Offer, the Fund will accept for payment, and pay for, up to 100% of the Fund’s outstanding Shares, or 10,848,022 Shares in the aggregate, validly tendered on or prior to 5:00 p.m., New York City time, on October 1, 2024, or if the Offer is extended, on the next trading day after the day to which the Offer is extended (the “Termination Date”) and not properly withdrawn as permitted by Section 4.

If the number of Shares properly tendered and not properly withdrawn prior to the Termination Date is less than or equal to the Offer Amount, the Fund will, upon the terms and conditions of the Offer, purchase all Shares so tendered Except as described herein, withdrawal rights expire on the Termination Date. If Shares duly tendered by or on behalf of a Stockholder include Shares held pursuant to the Fund’s dividend reinvestment plan, the proration will be applied first with respect to other Shares tendered and only thereafter, if and as necessary, with respect to Shares held pursuant to that plan. The Fund does not contemplate extending the Offer. Following the Offer, if less than $50 million of net assets remain in the Fund, the Offer will be cancelled and the Fund will liquidate on or about December 2, 2024.

Stockholders should consider the relative costs of tendering Shares pursuant to the Offer and selling Shares at the market price with the associated transaction costs.

The Fund expressly reserves the right, in its sole discretion, at any time or from time to time, to extend the period of time during which the Offer is open by giving oral or written notice of such extension to the Depositary. Any such extension will also be publicly announced by press release issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Termination Date. If the Fund makes a material change in the terms of the Offer or the information concerning the Offer, or if it waives a material condition of the Offer, the Fund will extend the Offer to the extent required by rules promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These rules require that the minimum period during which the Offer must remain open following material changes in the terms of the offer or information concerning the offer (other than a change in price or a change in percentage of securities sought) will depend on the facts and circumstances, including the relative materiality of such terms or information. During the extension, all Shares properly tendered and not properly withdrawn previously will remain subject to the Offer, subject to the right of a tendering Stockholder to withdraw his or her Shares.

Subject to the terms and conditions of the Offer, the Fund will pay the consideration offered or return the tendered securities promptly after the termination or withdrawal of the Offer in accordance with the terms as set forth in Section 2 below. Any extension, delay or termination will be followed as promptly as practicable by public announcement thereof, such announcement, in the case of an extension, to be issued no later than 9:00 a.m., New York City time, on the next business day after the previously scheduled Termination Date.

2. Acceptance for Payment and Payment for Shares

Upon the terms and subject to the conditions of the Offer, the Fund will accept for payment, and will pay for, Shares validly tendered on or before the Termination Date, and not properly withdrawn in accordance with Section 4 promptly after the Termination Date. In all cases, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depositary of certificates for such Shares (unless such Shares are held in uncertificated form), a properly completed and duly executed Letter of Transmittal (or facsimile thereof), and any other documents required by the Letter of Transmittal. The Fund expressly reserves the right, in its sole discretion, to delay the acceptance for payment of, or payment for, Shares, in whole or in part, in order to comply with any applicable law.

For purposes of the Offer, the Fund will be deemed to have accepted for payment Shares validly tendered and not properly withdrawn as, if and when the Fund gives oral or written notice to the Depositary of its acceptance for payment of such Shares pursuant to the Offer. Payment for Shares accepted for payment pursuant to the Offer will be made by deposit of the aggregate purchase price therefor with the Depositary, which will act as agent for the tendering Stockholders for purpose of receiving payments from the Fund and transmitting such payments to the tendering Stockholders. Under no circumstances will interest on the purchase price for Shares be paid, regardless of any delay in making such payment.

9

In the event of proration, the Fund will determine the proration factor and pay for those tendered Shares accepted for payment as soon as practicable after the Termination Date. However, the Fund expects that it will not be able to announce the final results of any proration or commence payment for any Shares purchased pursuant to the Offer until at least three business days after the Termination Date.

If any tendered Shares are not accepted for payment pursuant to the terms and conditions of the Offer for any reason, or are not paid because of an invalid tender, or if certificates are submitted for more Shares than are tendered (i) Shares delivered pursuant to the Book-Entry Delivery Procedure (as defined in Section 3 below) will be credited to the appropriate account maintained within the appropriate Book-Entry Transfer Facility and (ii) uncertificated Shares held by the Fund’s transfer agent pursuant to the Fund’s dividend reinvestment plan will be returned to the dividend reinvestment plan account maintained by the transfer agent.

If the Fund is delayed in its acceptance for payment of, or in its payment for, Shares, or is unable to accept for payment or pay for Shares pursuant to the Offer for any reason, then, without prejudice to the Fund’s rights under this Offer, the Depositary may, on behalf of the Fund, retain tendered Shares, and such Shares may not be withdrawn, unless and except to the extent tendering Stockholders are entitled to withdrawal rights as described in Section 4 of this Offer to Purchase.

The purchase price of the Shares will equal 100% of their NAV as of the close of regular trading session on the NYSE on October 1, 2024, or if the Offer is extended, on the next trading day after the day to which the Offer is extended (the “Pricing Date”). Tendering Stockholders may be required to pay brokerage commissions or fees. Under the circumstances set forth in Instruction 6 of the Letter of Transmittal, Stockholders may be obligated to pay transfer taxes on the purchase of Shares by the Fund.

The Fund normally calculates the NAV of its Shares daily at the close of the regular trading session (normally 5:00 p.m. New York City time) of the NYSE. On August 12, 2024, the NAV was $17.75 per Share. The Shares are listed on the NYSE. On August 12, 2024, the last sales price at the close of regular trading on the NYSE was $17.49 per Share, representing a 1.46% discount from NAV. The NAV of the Fund’s Shares will be available daily until the Termination Date, by calling the Fund’s Information Agent, toll free at (866) 461-7052 or through the Fund’s toll free number at (888) 777-0102.

3. Procedure for Tendering Shares

Stockholders having Shares that are registered in the name of a broker, dealer, commercial bank, trust company or other nominee should contact such firm if they desire to tender their Shares. For a Stockholder validly to tender Shares pursuant to the Offer, (i) a properly completed and duly executed Letter of Transmittal, together with any required signature guarantees, or in the case of a book-entry transfer, an Agent’s Message, and any other documents required by the Letter of Transmittal, must be transmitted to and received by the Depositary at one of its addresses set forth on the last page of this Offer to Purchase, and (ii) either the certificate for Shares must be transmitted to and received by the Depositary at one of its addresses set forth on the last page of this Offer to Purchase or the tendering Stockholder must comply with the Book-Entry Delivery Procedure set forth in this Section 3, in all cases prior to the Termination Date.

The Fund’s transfer agent holds Shares in uncertificated form for certain Stockholders pursuant to the Fund’s dividend reinvestment plan. Stockholders may tender such uncertificated Shares by completing the appropriate section of the Letter of Transmittal.

Signatures on Letters of Transmittal must be guaranteed by a firm which is a broker, dealer, commercial bank, credit union, savings association or other entity and which is a member in good standing of a stock transfer association’s approved medallion program (such as STAMP, SEMP or MSP) (each, an “Eligible Institution”) unless (i) the Letter of Transmittal is signed by the registered holder of the Shares tendered, including those Stockholders who are participants in a Book-Entry Transfer Facility and whose name appears on a security position listing as the owner of the Shares, but excluding those registered Stockholders who have completed either the “Special Transfer Instruction” box or the “Special Mailing Instruction” box on the Letter of Transmittal, or (ii) such Shares are tendered for the account of an Eligible Institution. In all other cases, all signatures on the Letter of Transmittal must be guaranteed by an Eligible Institution. See Instruction 5 of the Letter of Transmittal for further information.

10

Backup Federal Income Tax Withholding. Payments made pursuant to the Offer may be subject to information reporting. Backup withholding tax (at a rate of 24%) will generally be imposed on the gross proceeds paid to a tendering U.S. Stockholder (as defined in Section 8) unless (i) the U.S. Stockholder provides such U.S. Stockholder’s taxpayer identification number (employer identification number or social security number) to the applicable withholding agent, certifies as to no loss of exemption from backup withholding and complies with applicable requirements of the backup withholding rules, or (ii) such U.S. Stockholder is otherwise exempt from backup withholding. Therefore, each tendering U.S. Stockholder should complete and sign the Internal Revenue Service (“IRS”) Form W-9 included as part of the Letter of Transmittal so as to provide the information and certification necessary to avoid backup withholding, unless such U.S. Stockholder otherwise establishes to the satisfaction of the applicable withholding agent that such U.S. Stockholder is not subject to backup withholding. Certain U.S. Stockholders (including, among others, most corporations) are not subject to these backup withholding requirements. In addition, Non-U.S. Stockholders (as defined in Section 8) are not subject to these backup withholding requirements. In order for a Non-U.S. Stockholder to establish that it is not subject to backup withholding requirements, such Non-U.S. Stockholder must submit an applicable IRS Form W-8 (generally, an IRS Form W-8BEN, W-8BEN-E or W-8ECI). Such forms can be obtained from the Depositary. Backup withholding is not an additional tax and any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a stockholder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

For a discussion of certain federal income tax consequences to tendering Stockholders, see Section 8.

Withholding for Non-U.S. Stockholders. The tax treatment of a Stockholder’s receipt of cash pursuant to the Offer depends upon facts which may be unique as to each Stockholder. Therefore, even if a Non-U.S. Stockholder has provided the required certification to avoid backup withholding, an applicable withholding agent may withhold U.S. federal income tax equal to 30% of the gross proceeds payable to a Non-U.S. Stockholder unless the agent determines that a reduced rate of withholding is available pursuant to a tax treaty or that an exemption from withholding is applicable because such gross proceeds are effectively connected with the Non-U.S. Stockholder’s conduct of a trade or business within the U.S. (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Stockholder). In order to obtain a reduced rate of withholding pursuant to a tax treaty, a Non-U.S. Stockholder must deliver a properly completed and executed IRS Form W-8BEN (for individuals) or Form W-8BEN-E (for entities). In order to obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the U.S. (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Stockholder), a Non-U.S. Stockholder must deliver a properly completed and executed IRS Form W-8ECI. A withholding agent may determine a Stockholder’s status as a Non-U.S. Stockholder and eligibility for a reduced rate of, or exemption from, withholding by reference to any outstanding certificates or statements concerning eligibility for a reduced rate of, or exemption from, withholding (e.g., IRS Forms W-8BEN, W-8BEN-E or W-8ECI) unless facts and circumstances indicate that such reliance is not warranted. A Non-U.S. Stockholder may be eligible to obtain a refund of all or a portion of any tax withheld if such Non-U.S. Stockholder satisfies certain requirements or is otherwise able to establish that no tax or a reduced amount of tax is due (See Section 8). Backup withholding generally will not apply to amounts subject to the 30% or a treaty-reduced rate of withholding. Non-U.S. Stockholders are urged to consult their own tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the refund procedure.

In addition, a Non-U.S. Stockholder (other than an individual) may be subject to a 30% withholding tax under Sections 1471 through 1474 of the Internal Revenue Code of 1986, as amended (the “Code”), commonly referred to as “FATCA,” unless such Non-U.S. Stockholder establishes an exemption from such withholding tax under FATCA, typically on IRS Form W-8BEN-E. In such case, any withholding under FATCA may be credited against, and therefore reduce, any 30% or treaty-reduced rate of withholding as discussed above.

All questions as to the validity, form, eligibility (including time of receipt), payment and acceptance for payment of any tender of Shares will be determined by the Fund in its sole discretion, which determination shall be final and binding. The Fund reserves the absolute right to reject any and all tenders of Shares it determines not to be in proper form or the acceptance for payment of which may, in the opinion of its counsel, be unlawful. The Fund also reserves the absolute right to waive any of the conditions of the Offer or any defect or irregularity in the tender of any

11

Shares. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived. None of the Fund, the Investment Manager, the Subadvisers, the Information Agent, the Depositary or any other person shall be under any duty to give notification of any defects or irregularities in tenders, nor shall any of the foregoing incur any liability for failure to give any such notification. The Fund’s interpretation of the terms and conditions of the Offer (including the Letter of Transmittal and instructions thereto) will be final and binding.

Payment for Shares tendered and accepted for payment pursuant to the Offer will be made, in all cases, only after timely receipt of (i) certificates for such Shares by the Depositary or book-entry confirmation of delivery of such Shares to the account of the Depositary, (ii) a properly completed and duly executed Letter of Transmittal (or facsimile thereof) for such Shares, and (iii) any other documents required by the Letter of Transmittal. The tender of Shares pursuant to any of the procedures described in this Section 3 will constitute an agreement between the tendering Stockholder and the Fund upon the terms and subject to the conditions of the Offer.

The method of delivery of all required documents is at the election and risk of each tendering Stockholder. If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended.

Book-Entry Delivery Procedure

The Depositary will establish accounts with respect to the Shares at the Depository Trust Company (the “Book-Entry Transfer Facility”) for purposes of the Offer promptly after the date of this Offer. Any financial institution that is a participant in any of the Book-Entry Transfer Facility’s systems may make delivery of tendered Shares by (i) causing such Book-Entry Transfer Facility to transfer such Shares into the Depositary’s account in accordance with such Book-Entry Transfer Facility’s procedure for such transfer and (ii) causing a confirmation of receipt of such delivery to be received by the Depositary (the “Book-Entry Delivery Procedure”). The Book-Entry Transfer Facility may charge the account of such financial institution for tendering Shares on behalf of Stockholders. Notwithstanding that delivery of Shares may be properly effected in accordance with this Book-Entry Delivery Procedure, the Letter of Transmittal, with signature guarantee, or an Agent’s Message, and all other documents required by the Letter of Transmittal must be transmitted to and received by the Depositary at the appropriate address set forth on the last page of this Offer before the Termination Date. Delivery of documents to a Book-Entry Transfer Facility in accordance with such Book-Entry Transfer Facility’s procedures does not constitute delivery to the Depositary for purposes of this Offer.

The confirmation of a book-entry transfer of Shares into the Depositary’s account at the Book-Entry Transfer Facility described above is referred to herein as a “book-entry confirmation.”

The term “Agent’s Message” means a message transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a book-entry confirmation, stating that the Book-Entry Transfer Facility has received an express acknowledgment from the participant tendering Shares through the Book-Entry Transfer Facility that the participant has received and agrees to be bound by the terms of the Letter of Transmittal and that the Fund may enforce that agreement against that participant.

4. Rights of Withdrawal

Tenders of Shares made pursuant to the Offer may be withdrawn at any time prior to the Termination Date (October 1, 2024), unless extended.

To be effective, a written notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the last page of this Offer to Purchase. Any notice of withdrawal must specify the name of the person who executed the particular Letter of Transmittal, the number of Shares to be withdrawn, and the names in which the Shares to be withdrawn are registered. Any signature on the notice of withdrawal must be guaranteed by an Eligible Institution. If certificates have been delivered to the Depositary, the name of the registered holder and the serial numbers of the particular certificates evidencing the Shares withdrawn must be furnished to the Depositary. If Shares have been delivered pursuant to the Book-Entry Delivery Procedure set forth in Section 3 of this Offer to Purchase, any notice of withdrawal must specify the name and number of the account at the Book-Entry Transfer Facility to be credited with the withdrawn Shares (which must be the same name, number, and Book-Entry Transfer Facility from which the Shares were tendered), and must comply with the procedures of the Book-Entry Transfer Facility.

12

All questions as to the form and validity, including time of receipt, of any notice of withdrawal will be determined by the Fund, in its sole discretion, which determination shall be final and binding. None of the Fund, the Investment Manager, the Subadvisers, the Information Agent, the Depositary or any other person shall be under any duty to give notification of any defects or irregularities in any notice of withdrawal nor shall any of the foregoing incur any liability for failure to give such notification. Any Shares properly withdrawn will be deemed not to have been validly tendered for purposes of the Offer. However, withdrawn Shares may be re-tendered by following the procedures described in Section 3 of this Offer to Purchase at any time prior to the Termination Date.

If the Fund is delayed in its acceptance for payment of Shares, or it is unable to accept for payment Shares tendered pursuant to the Offer, for any reason, then, without prejudice to the Fund’s rights under this Offer, the Depositary may, on behalf of the Fund, retain tendered Shares, and such Shares may not be withdrawn except to the extent that tendering Stockholders are entitled to withdrawal rights as set forth in this Section 4.

5. Source and Amount of Funds; Effect of the Offer

The actual cost of the Offer to the Fund cannot be determined at this time because the number of Shares to be purchased will depend on the number tendered, and the price will be based on the NAV per Share on the Pricing Date (October 1, 2024, unless extended). If the NAV per Share on the Pricing Date were the same as the NAV per Share on August 12, 2024, and if Stockholders tender 100% of the Fund’s outstanding Shares pursuant to the Offer, the estimated payment by the Fund to the Stockholders would be approximately $192,552,390. However, if, following the Offer, less than $50 million of net assets remain in the Fund, the Offer will be cancelled and the Fund will liquidate on or about December 2, 2024.

The monies to be used by the Fund to purchase Shares pursuant to the Offer will be obtained from an increase in the Fund’s use of leverage, cash and/or from sales of securities in the Fund’s investment portfolio.

The Offer may have certain adverse consequences for tendering and non-tendering Stockholders.

Effect on NAV and Consideration Received by Tendering Stockholders. If the Fund were required to sell a substantial amount of portfolio securities to raise cash to finance the Offer, the market prices of portfolio securities being sold and/or the Fund’s remaining portfolio securities may decline and hence the Fund’s NAV may decline. If any such decline occurs in the value of portfolio securities, the Fund cannot predict what its magnitude might be or whether such a decline would be temporary or continue to or beyond the Termination Date (October 1, 2024). Because the price per Share to be paid in the Offer will be dependent upon the NAV per Share as determined on the Termination Date, if such a decline continued up to the Termination Date (October 1, 2024, unless extended), the consideration received by tendering Stockholders would be reduced. In addition, the sale of portfolio securities will cause the Fund to incur increased brokerage and related transaction expenses, and the Fund may receive proceeds from the sale of portfolio securities that are less than their valuations by the Fund. Accordingly, obtaining the cash to consummate the Offer may result in a decrease in the Fund’s NAV per Share, thereby reducing the amount of proceeds received by tendering Stockholders and the NAV per Share for non-tendering Stockholders.

The Fund will likely sell portfolio securities during the pendency of the Offer to raise cash for the purchase of Shares. Thus, during the pendency of the Offer, and possibly for a short time thereafter, the Fund will likely hold a greater than normal percentage of its net assets in cash and cash equivalents. The Fund will pay for tendered Shares it accepts for payment reasonably promptly after the Termination Date of this Offer. Because the Fund will not know the number of Shares tendered until the Termination Date, the Fund will not know until the Termination Date the amount of cash required to pay for such Shares. If on or prior to the Termination Date, the Fund does not have, or believes it is unlikely to have, sufficient cash to pay for all Shares tendered, it may extend the Offer to allow additional time to sell portfolio securities and raise sufficient cash.

Recognition of Capital Gains and Ordinary Income by the Fund. As noted, the Fund will likely be required to sell portfolio securities to finance the Offer. If the Fund’s tax basis for the securities sold is less than the sale proceeds, the Fund will recognize capital gains. The Fund would expect to declare and distribute any such gains to Stockholders of record (reduced by net capital losses realized during the fiscal year, if any, and any net capital loss carryforwards). In addition, some of the distributed gains may be realized on securities held for one year or less, which would generate income taxable to the non-tendering Stockholders at ordinary income rates. This recognition and distribution of gains, if any, would have certain negative consequences; first, Stockholders at the time of a declaration of distributions would be required to pay taxes on a greater amount of distributions than otherwise would be the case;

13

second, to raise cash to make the distributions, the Fund might need to sell additional portfolio securities thereby possibly being forced to realize and recognize additional capital gains. It is impossible to predict what the amount of unrealized gains or losses would be in the Fund’s portfolio at the time that the Fund is required to liquidate portfolio securities (and hence the amount of capital gains or losses that would be realized and recognized). As of August 12, 2024, there was net unrealized depreciation on a book basis of approximately $3,981,278 in the Fund’s portfolio as a whole. Additionally, as of August 12, 2024, the Fund had estimated net capital loss carryforwards, not subject to expiration, of $6,913,046 available for tax purposes to offset any future capital gains realized by the Fund. Depending on a number of factors, including the participation level of the Offer (which will not be known prior to the termination date of the Offer), the Offer may result in an ownership change of the Fund for U.S. federal income tax purposes. If there is an ownership change of the Fund, the Fund’s ability to use its net capital loss carryforwards would be subject to an annual limitation based on the value of the Fund’s equity at the time of the ownership change.

Higher Expense Ratio and Less Investment Flexibility. If the Fund purchases a substantial number of Shares pursuant to the Offer, the net assets of the Fund (that is, its total assets less its liabilities) will be reduced accordingly. The reduced net assets of the Fund as a result of the Offer will result in a higher expense ratio for the Fund and possibly in less investment flexibility for the Fund, depending on the number of Shares repurchased.

6. Purpose of the Offer; Plans or Proposals of the Fund

The Board of Directors of the Fund has authorized a tender offer to purchase for cash up to 100% of the Fund’s outstanding Shares, or up to 10,848,022 Shares, for cash at a price per share equal to 100% of the per share net asset value as of the close of regular trading on the New York Stock Exchange (“NYSE”) on October 1, 2024 (or if the Offer is extended, on the next trading day after the day to which the Offer is extended), upon specified terms and subject to conditions as set forth in the Offer documents.

The purpose of this Offer is to provide liquidity to Stockholders. The Offer may reduce any market price discount from the NAV of the Shares, but there can be no assurance that this Offer will result in such a reduction. The market price of the Shares will also be determined by, among other things, the relative demand for and supply of the Shares in the market, the Fund’s investment performance, the Fund’s dividends and yield, investor perception of the Fund’s overall attractiveness as an investment as compared with other investment alternatives, and current market events. Following the Offer, if less than $50 million of net assets remain in the Fund, the Offer will be cancelled and the Fund will liquidate on or about December 2, 2024.

The purchase of Shares pursuant to the Offer will have the effect of increasing the proportionate interest in the Fund of Stockholders that do not tender Shares. Stockholders that retain their Shares may be subject to increased risks due to a reduction in the Fund’s aggregate assets resulting from payment for the Shares tendered. These risks include the potential for greater volatility in our NAV due to possible decreased diversification. However, the Fund believes that this result is unlikely given the nature of the Fund’s investment program. A reduction in the aggregate assets of the Fund may result in Stockholders that do not tender Shares bearing higher costs to the extent that certain expenses borne by the Fund are relatively stable and may not decrease if assets decline.

Any Shares acquired by the Fund pursuant to the Offer will become authorized but unissued Shares and will be available for issuance by the Fund without further Stockholder action (except as required by applicable law or the rules of national securities exchanges on which the Shares are listed).

Except as set forth above, as referred to in connection with the Fund’s Dividend Reinvestment Plan, the Fund does not have any present plans or proposals and is not engaged in any negotiations that relate to or would result in: (a) other than in connection with transactions in the ordinary course of the Fund’s operations and for purposes of funding the Offer, any purchase, sale or transfer of a material amount of assets of the Fund or any of its subsidiaries; (b) any material change in the Fund’s present dividend policy, or indebtedness or capitalization of the Fund; (c) changes to the present Board of Directors or management of the Fund, including changes to the number or the term of members of the Board of Directors, the filling of any existing vacancies on the Board of Directors or changes to any material term of the employment contract of any executive officer; (d) any other material change in the Fund’s corporate structure or business, including any plans or proposals to make any changes in the Fund’s investment policy for which a vote would be required by Section 13 of the 1940 Act; (e) any class of equity securities of the Fund being delisted from a national securities exchange or ceasing to be authorized to be quoted in an automated quotations system operated by a national securities association; (f) any class of equity securities of the Fund becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; (g) the suspension of the Fund’s

14

obligation to file reports pursuant to Section 15(d) of the Exchange Act; (h) the acquisition by any person of additional securities of the Fund, or the disposition of securities of the Fund; or (i) any changes in the Fund’s Articles of Incorporation, By-Laws or other governing instruments or other actions that could impede the acquisition of control of the Fund. Following the completion of the Offer, the Board of Directors reserves the right to consider whether a merger or reorganization of the Fund, other extraordinary transaction or restructuring of the Fund’s outstanding senior securities, or any other plans noted above, would be appropriate. No other tender offers are presently contemplated, but the Board of Directors reserves the right to conduct tender offers in the future.

NONE OF THE FUND, ITS BOARD OF DIRECTORS, THE INVESTMENT MANAGER OR THE SUBADVISERS MAKES ANY RECOMMENDATION TO ANY STOCKHOLDER AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ANY OF SUCH STOCKHOLDER’S SHARES, AND NONE OF SUCH PERSONS HAS AUTHORIZED ANY PERSON TO MAKE ANY SUCH RECOMMENDATION. STOCKHOLDERS ARE URGED TO EVALUATE CAREFULLY ALL INFORMATION IN THE OFFER, CONSULT THEIR OWN INVESTMENT AND TAX ADVISORS AND MAKE THEIR OWN DECISIONS WHETHER TO TENDER SHARES.

7. NAV and Market Price Range of Shares; Dividends

The Shares are traded on the NYSE. The following table sets forth for the fiscal quarters indicated the NAV (as of the last day of each of such fiscal quarters) and the high and low NYSE Market Price per Share:

As of the close of business on August 12, 2024, the Fund’s NAV per Share was $17.75. The tender of Shares, unless and until such tendered Shares are accepted for purchase, will not affect the record ownership of any such tendered Shares for purposes of entitlement to any dividends payable by the Fund.

8. Federal Income Tax Consequences of the Offer

The following discussion describes certain U.S. federal income tax consequences to U.S. Stockholders and Non-U.S. Stockholders (each as defined below and collectively, for purposes of this discussion, “Stockholders”) of the exchange of Shares for cash pursuant to the Offer. This summary deals only with Shares held as capital assets (generally, property held for investment) and does not deal with all tax consequences that may be relevant to Stockholders in light of their particular circumstances or to Stockholders subject to special tax rules (including, without limitation, partnerships or other pass-through entities (and investors therein), regulated investment companies, real estate investment trusts, dealers in securities or currencies, traders in securities that elect to mark their holdings to market, financial institutions, tax-exempt organizations, insurance companies, U.S. expatriates, certain former long-term residents of the U.S., persons liable for alternative minimum tax, persons holding Shares as a part of a hedging, conversion or constructive sale transaction or a straddle, U.S. Stockholders whose functional currency is not the U.S. dollar, or persons who acquired their Shares as compensation or pursuant to employee stock options or employee benefit plans). Furthermore, the discussion below is based upon the Code, U.S. Treasury regulations, administrative rulings and pronouncements and judicial decisions, as of the date hereof, all of which may be repealed, revoked or modified, possibly with retroactive effect, so as to result in U.S. federal income tax consequences different from those discussed below. This summary does not address all aspects of U.S. federal income taxes and does not address any United States tax considerations (e.g., estate or gift tax) other than United States federal income tax considerations, the consequences of any alternative minimum tax, the Medicare

15

contribution tax on net investment income, special tax accounting rules that apply to certain accrual basis taxpayers under Section 451(b) of the Code or any foreign, state, local or other tax considerations that may be relevant to Stockholders in light of their particular circumstances. Stockholders should consult their own tax advisors concerning the U.S. federal income tax consequences of participating in the Offer in light of their particular situations as well as any consequences arising under other U.S. federal laws or the laws of any other taxing jurisdiction.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Shares, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership or a partner of a partnership holding Shares, you should consult your tax advisors.

As used herein, a “U.S. Stockholder” means a beneficial owner of Shares that is, for U.S. federal income tax purposes, (i) an individual who is a citizen or resident of the U.S., (ii) a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the U.S. or any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (iv) a trust if it (x) is subject to the primary supervision of a court within the U.S. and one or more U.S. persons have the authority to control all substantial decisions of the trust or (y) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person. A “Non-U.S. Stockholder” is a beneficial owner of Shares that is neither a U.S. Stockholder nor a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes).

Stockholders who do not participate in the Offer will not incur any U.S. federal income tax as a result of the exchange of Shares for cash by other Stockholders pursuant to the Offer.

U.S. Stockholders. An exchange of Shares for cash in the Offer will be a taxable transaction for U.S. federal income tax purposes. As a consequence of the exchange, a tendering U.S. Stockholder will, depending on such U.S. Stockholder’s particular circumstances, be treated either as recognizing gain or loss from the sale or exchange of the Shares or as receiving a distribution from the Fund. Under Section 302(b) of the Code, an exchange of Shares for cash pursuant to the Offer generally will be treated as a sale or exchange for U.S. federal income tax purposes if the exchange: (a) results in a complete termination of the U.S. Stockholder’s interest in the Fund, (b) results in a substantially disproportionate redemption with respect to the U.S. Stockholder or (c) is not essentially equivalent to a dividend with respect to the U.S. Stockholder. In determining whether any of these tests has been met, Shares actually owned, as well as Shares considered to be owned by the U.S. Stockholder by reason of certain constructive ownership rules set forth in Section 318 of the Code, generally must be taken into account.

The sale of Shares pursuant to the Offer will result in a “complete termination” of a U.S. Stockholder’s interest in the Fund if either (i) all Shares actually and constructively owned by the U.S. Stockholder are exchanged for cash pursuant to the Offer or (ii) all Shares actually owned by the U.S. Stockholder are exchanged for cash pursuant to the Offer and the U.S. Stockholder is eligible to waive, and effectively waives, the attribution of all stock in the Fund constructively owned by the U.S. Stockholder in accordance with the procedures described in Section 302(c)(2) of the Code.

The sale of Shares pursuant to the Offer generally will result in a “substantially disproportionate” redemption with respect to a U.S. Stockholder if (i) the percentage of the Fund’s then outstanding Shares actually and constructively owned by the U.S. Stockholder immediately after the sale (treating all Shares purchased by the Fund pursuant to the Offer as not outstanding) is less than 80% of the percentage of the Fund’s then outstanding Shares actually and constructively owned by the U.S. Stockholder determined immediately before the sale (treating all Shares purchased by the Fund pursuant to the Offer as outstanding) and (ii) immediately following the sale the U.S. Stockholder actually and constructively owns less than 50% of the total outstanding Shares.

The sale of Shares pursuant to the Offer generally will be treated as “not essentially equivalent to a dividend” with respect to a U.S. Stockholder if it results in a “meaningful reduction” in the U.S. Stockholder’s proportionate interest in the Fund’s stock. Generally, even a small reduction in the percentage ownership interest of a stockholder in a publicly held corporation (such as the Fund) whose relative stock interest is minimal and who exercises no control over the corporation’s business should constitute a meaningful reduction.

16

Proration may affect whether the sale of Shares pursuant to the Offer will meet any of the three tests under Section 302(b) of the Code described above. Contemporaneous dispositions or acquisitions of Shares by a U.S. Stockholder or related individuals or entities may also be deemed to be part of a single integrated transaction and may be taken into account in determining whether any of the three tests under Section 302(b) of the Code have been satisfied.

If any of the above three tests under Section 302(b) of the Code for sale or exchange treatment is met, a U.S. Stockholder will recognize gain or loss equal to the difference between the price paid by the Fund for the Shares purchased in the Offer and the U.S. Stockholder’s adjusted basis in such Shares. The gain or loss will generally be capital gain or loss. Such capital gain or loss will generally be long-term capital gain or loss if the Shares have been held for more than one year or short-term capital gain or loss if the Shares have been held for one year or less. However, any loss realized by a U.S. Stockholder on the sale of Shares held by the U.S. Stockholder for six months or less will be treated as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the U.S. Stockholder with respect to such Shares. The maximum tax rate applicable to capital gains recognized by individuals and other non-corporate taxpayers is (i) the same as the applicable ordinary income rate for short-term capital gains or (ii) 20% for long-term capital gains. The deductibility of capital losses is subject to limitations. Generally, gain or loss must be determined separately for each block of Shares (generally, Shares acquired by a U.S. Stockholder at the same cost in a single transaction) the Fund purchases in the Offer. Any loss realized by a U.S. Stockholder on the sale of Shares pursuant to the Offer will be disallowed to the extent the U.S. Stockholder acquires (including pursuant to the Fund’s dividend reinvestment plan), or enters into a contract or option to acquire, shares that are substantially identical to such Shares within 30 days before or after the sale. In such a case, the basis of the replacement shares will be adjusted to reflect the disallowed loss.

In addition, under U.S. Treasury regulations directed at tax shelter activity, if a U.S. Stockholder recognizes a loss with respect to the Shares of $2 million or more for an individual U.S. Stockholder or $10 million or more for a corporate U.S. Stockholder, the U.S. Stockholder must file with the IRS a disclosure statement on IRS Form 8886. Direct holders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, stockholders of a regulated investment company, such as the Fund, are not excepted. Future guidance may extend the current exception from this reporting requirement to stockholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. U.S. Stockholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

If a U.S. Stockholder’s sale of Shares pursuant to the Offer does not meet any of the above three tests under Section 302(b) of the Code for sale or exchange treatment, amounts received by the U.S. Stockholder pursuant to the Offer will be treated as a distribution with respect to the Shares that are sold and will generally be taxable to the U.S. Stockholder as ordinary dividend income to the extent of such U.S. Stockholder’s allocable share of the Fund’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). The Fund does not expect any such dividend income to be eligible for the dividends received deduction allowed to U.S. corporations or for the reduced U.S. federal income tax rates that are currently imposed on certain “qualified dividend income” received by non-corporate U.S. Stockholders. To the extent that amounts received by a U.S. Stockholder pursuant to the Offer exceed such U.S. Stockholder’s allocable share of the Fund’s current and accumulated earnings and profits, the excess will first be treated as a non-taxable return of capital, causing a reduction in the adjusted basis of the Shares that are sold, and any amounts in excess of the adjusted basis will constitute capital gain (as described above). Any remaining adjusted basis in the Shares sold to the Fund by a U.S. Stockholder will be transferred to any remaining Shares held by such U.S. Stockholder.

Non-U.S. Stockholders. The U.S. federal income taxation of a Non-U.S. Stockholder with respect to an exchange of Shares for cash pursuant to the Offer will depend on the tax characterization of the transaction, determined in the same manner as discussed above for U.S. Stockholders. Generally, if the exchange is treated as a sale or exchange under Section 302(b) of the Code, any gain realized by a Non-U.S. Stockholder will not be subject to U.S. federal income tax unless (i) such gain is effectively connected with a trade or business carried on in the U.S. by such Non-U.S. Stockholder (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Stockholder) or (ii) the Non-U.S. Stockholder is an individual who is physically present in the U.S. for 183 days or more during the taxable year of the exchange and certain other conditions are met. A Non-U.S. Stockholder described in clause (i) above will generally be subject to U.S. federal

17

income tax on the gain derived from the exchange in the same manner as if the Non-U.S. Stockholder were a U.S. Stockholder. A Non-U.S. Stockholder that is a corporation may be subject to an additional “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) with respect to any effectively connected earnings and profits attributable to such gain (subject to certain adjustments). An individual Non-U.S. Stockholder described in clause (ii) above will generally be subject to U.S. federal income tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on the gain derived from the exchange, which may be offset by certain U.S. source capital losses, even though the Non-U.S. Stockholder is not considered a resident of the U.S.

If, however, a Non-U.S. Stockholder’s exchange of Shares for cash pursuant to the Offer does not satisfy any of the above three tests under Section 302(b) of the Code for sale or exchange treatment, amounts received by such Non-U.S. Stockholder pursuant to the Offer will be treated as a distribution with respect to the Shares that are exchanged. The treatment for U.S. federal income tax purposes of such distribution as a dividend, return of capital, or as gain from the sale of Shares will be determined in the same manner described above for U.S. Stockholders. In general, and subject to any statutory exemption (for example, the exemption for any “capital gain dividend,” “interest-related dividend,” or “short-term capital gain dividend”) and the discussion below of effectively connected dividends, any amount that constitutes a dividend for U.S. federal income tax purposes will be subject to U.S. withholding tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty). The tax treatment of a Stockholder’s receipt of cash pursuant to the Offer depends upon facts which may be unique as to each Stockholder. Therefore, because an applicable withholding agent may not be able to determine if a particular Non-U.S. Stockholder qualifies for sale or exchange treatment under Section 302(b) of the Code, such agent may withhold U.S. federal income tax equal to 30% of the gross proceeds payable to such Non-U.S. Stockholder unless the agent determines that a reduced rate of withholding is available pursuant to a tax treaty or that an exemption from withholding is applicable because such gross proceeds are effectively connected with the Non-U.S. Stockholder’s conduct of a trade or business within the U.S. (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Stockholder). In order to obtain a reduced rate of withholding pursuant to a tax treaty, a Non-U.S. Stockholder must deliver a properly completed and executed IRS Form W-8BEN (for individuals) or Form W-8BEN-E (for entities). In order to obtain an exemption from withholding on the grounds that the gross proceeds paid pursuant to the Offer are effectively connected with the conduct of a trade or business within the U.S. (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Stockholder), a Non-U.S. Stockholder must deliver a properly completed and executed IRS Form W-8ECI. Any such effectively connected amounts will generally be subject to U.S. federal income tax (and possibly branch profits tax) in the same manner as effectively connected gains as described above. A Non-

U.S. Stockholder may be eligible to obtain a refund of all or a portion of any tax withheld if such Non-U.S. Stockholder meets one of the Section 302(b) tests described above or is otherwise able to establish that no tax or a reduced amount of tax is due. Backup withholding generally will not apply to amounts subject to the 30% or a treaty-reduced rate of withholding. Non-U.S. Stockholders are urged to consult their own tax advisors regarding the application of U.S. federal income tax withholding, including eligibility for a withholding tax reduction or exemption, and the refund procedure.

Under Sections 1471 through 1474 of the Code, commonly referred to as “FATCA,” and administrative guidance, a U.S. federal withholding tax of 30% generally will be imposed on dividends that are paid to “foreign financial institutions” and “non-financial foreign entities” (as specifically defined under these rules and whether such institutions or entities hold Shares as beneficial owners or intermediaries), unless specified requirements are met. Because, as discussed above, a withholding agent may treat amounts paid to Non-U.S. Stockholders in the Offer as dividends for U.S. federal income tax purposes, such amounts may also be subject to withholding under FATCA if such requirements are not met. In such case, any withholding under FATCA may be credited against, and therefore reduce, any 30% or treaty-reduced rate of withholding as discussed above.

Backup Withholding. See Section 3 with respect to the application of backup withholding on payments made to Stockholders.

The tax discussion set forth above is included for general information only. Each Stockholder is urged to consult its own tax advisor to determine the particular tax consequences to it of the Offer, including the applicability and effect of state, local and foreign tax laws.

10. Certain Information Concerning the Fund, the Investment Manager and the Subadvisers

The Fund is a closed-end, non-diversified management investment company organized as a Maryland corporation. The Shares were first issued to the public on June 26, 2009. As a closed-ended investment company, the Fund differs from an open-end investment company (i.e., a mutual fund) in that it does not redeem its Shares at the election of a Stockholder and does not continuously offer its Shares for sale to the public. The Fund seeks to provide current income. As a secondary objective, the Fund seeks capital appreciation. Under normal market conditions, the Fund invests at least 80% of its net assets in investment grade corporate fixed income securities of varying maturities. The Fund may invest up to 20% of its net assets in corporate fixed income securities of below investment grade quality (commonly known as “high yield” or “junk” bonds) at the time of investment and other securities, including obligations of the U.S. government, its agencies or instrumentalities, common stocks, warrants and depositary receipts. For purposes of the 20% policy, while the Fund may invest up to 20% of its net assets in below investment grade securities, the Fund will, under normal market conditions, maintain a portfolio with an overall dollar-weighted average of investment grade credit quality. The principal executive offices and business address of the Fund are located at 620 Eighth Avenue, 47th Floor, New York, NY 10018. The Fund’s business telephone number is (888) 777-0102.

The Investment Manager is a wholly-owned subsidiary of Franklin Resources, Inc. The Investment Manager is a limited liability company organized under the laws of Delaware on April 6, 2006 and an investment adviser registered under the Investment Advisers Act of 1940 (“Advisers Act”). The Investment Manager has served as the investment manager since the commencement of operations. The principal business address of the Investment Manager is 280 Park Avenue, New York, NY 10017. The Fund is sub-advised by the Subadvisers, each an affiliate of the Investment Manager.

The Fund is subject to the information and reporting requirements of the 1940 Act and in accordance therewith is obligated to file reports and other information with the SEC relating to its business, financial condition and other matters. The Fund has also filed an Offer to Purchase on Schedule TO with the SEC. Such reports and other information should be available for inspection at the public reference room at the SEC’s office, 100 F Street, N.E., Room 1580, Washington, D.C. 20549. The Fund’s filings are also available to the public on the SEC’s internet site (http://www.sec.gov).

Neither the Fund nor, to the best of the Fund’s knowledge, any of the Fund’s officers or directors, any person controlling the Fund, or any executive officer or director of any corporation or other person ultimately in control of the Fund, has effected any transaction in Shares, except for dividend reinvestments, during the past 60 days.

Neither the Fund nor, to the best of the Fund’s knowledge, any of the Fund’s officers or directors is a party to any other contract, arrangement, understanding or relationship with any other person relating, directly or indirectly to the Offer with respect to any securities of the Fund, including, but not limited to, any contract, arrangement, understanding or relationship concerning the transfer or the voting of any such securities, joint ventures, loan or option arrangements, puts or calls, guarantees of loans, guarantees against loss or the giving or withholding of proxies, consents or authorizations.

Based upon information provided or available to the Fund, no director, officer or affiliate of the Fund intends to tender Shares pursuant to this Offer.

12. Certain Legal Matters; Regulatory Approvals

The Fund is not aware of any approval or other action by any government or governmental, administrative or regulatory authority or agency, domestic or foreign, that would be required for the acquisition or ownership of Shares by the Fund as contemplated herein. Should any such approval or other action be required, the Fund currently contemplates that such approval or other action will be sought. The Fund is unable to predict whether it may determine that it is required to delay the acceptance for payment of, or payment for, Shares tendered pursuant to the Offer pending the outcome of any such matter. There can be no assurance that any such approval or other action, if needed, would be obtained without substantial conditions or that the failure to obtain any such approval or other action might not result in adverse consequences to the Fund’s business. The Fund’s obligations under the Offer to accept for payment and pay for Shares are subject to certain conditions described in Section  13.

13. Certain Conditions to the Offer

Notwithstanding any other provision of the Offer, the Fund will not commence the Offer or accept tenders of the Fund’s Shares during any period when (a) such transactions, if consummated, would result in the delisting of the Fund’s Shares from the NYSE; or (b) there is any (i) legal or regulatory action or proceeding instituted or threatened challenging such transaction, (ii) suspension of or limitation on prices for trading securities generally on the NYSE or other national securities exchange(s), including the Nasdaq Stock Market and the NYSE American, or (iii) declaration of a banking moratorium by federal or state authorities or any suspension of payment by banks in the United States or New York State. The Fund will commence the Offer if it is delayed by the pendency of any of the above described events within 20 days of the termination of such delaying event, as determined by the Fund in its sole discretion.

The foregoing conditions are for the sole benefit of the Fund and may be asserted by the Fund regardless of the circumstances (including any action or inaction by the Fund) giving rise to any such conditions or may be waived by the Fund in whole or in part at any time and from time to time in its sole discretion. The failure by the Fund at any time to exercise any of the foregoing rights shall not be deemed a waiver of any such right and each such right shall be deemed an ongoing right which may be asserted at any time and from time to time. Any determination by the Fund concerning the events described in this Section shall be final and binding on all parties.

A public announcement shall be made of a material change in, or waiver of, such conditions, and the Offer may, in certain circumstances, be extended in connection with any such change or waiver.

If the Offer is suspended or postponed, the Fund will provide notice to Stockholders of such suspension or postponement.

14. Fees and Expenses

The Fund will not pay to any broker or dealer, commercial bank, trust company or other person any solicitation fee for any Shares purchased pursuant to the Offer. No such broker, dealer, commercial bank, trust company or other person has been authorized to act as agent of the Fund or the Depositary for purposes of the Offer.

The Fund has retained Computershare Inc. and its wholly owned subsidiary, Computershare Trust Company, N.A. to act as Depositary and Georgeson LLC to act as Information Agent. The Depositary and the Information Agent will receive reasonable and customary compensation for their services and will also be reimbursed for certain out-of-pocket expenses, and will be indemnified against certain liabilities by the Investment Manager or its affiliates.

15. Miscellaneous

The Offer is not being made to (nor will tenders be accepted from or on behalf of) holders of Shares in any jurisdiction in which the making of the Offer or the acceptance thereof would not be in compliance with the laws of such jurisdiction. The Fund may, in its sole discretion, take such action as it may deem necessary to make the Offer in any such jurisdiction.

The Fund is not aware of any jurisdiction in which the making of the Offer or the acceptance of Shares in connection therewith would not be in compliance with the laws of such jurisdiction. Consequently, the Offer is currently being made to all holders of Shares. However, the Fund reserves the right to exclude Stockholders in any jurisdiction in which it is asserted that the Offer cannot lawfully be made. So long as the Fund makes a good faith effort to comply with any state law deemed applicable to the Offer, the Fund believes that the exclusion of Stockholders residing in such jurisdiction is permitted under Rule 13e-4(f)(9) promulgated under the Exchange Act.

16. Contacting the Depositary and the Information Agent

The Letter of Transmittal, certificates for the Shares and any other required documents should be sent by each Stockholder of the Fund or his or her broker-dealer, commercial bank, trust company or other nominee to the Depositary as set forth below.
