Treasury Series and Money Market Series are both series of Dryden Government Securities Trust (Government Securities Trust). A shareholder meeting for Treasury Series is scheduled for March 19, 2004. Only shareholders of Treasury Series will vote on the acquisition of Treasury Series' assets by Money Market Series. This package contains information about the proposal and includes materials you will need to vote. The Board of Trustees of Government Securities Trust has reviewed the proposal and recommended that it be presented to shareholders of Treasury Series for their consideration. Although the Trustees have determined that the proposal is in the best interests of shareholders, the final decision is up to you. If approved, the proposed transaction would give you the opportunity to participate in a fund with similar investment policies. In addition, approval of the proposed transaction will reduce the amount of an expected increase in the expenses borne by shareholders of Treasury Series caused by the large-scale redemption of shares of Treasury Series held by Wachovia Securities LLC (Wachovia) for brokerage customers. To help you understand the proposal, we are including a "Q and A" section that answers common questions about the proposed transaction. The accompanying proxy statement and prospectus includes a detailed description of the proposal. Please read the enclosed materials carefully and cast your vote. Remember, your vote is extremely important, no matter how large or small your holdings. By voting now, you can help avoid additional costs that would be incurred with follow-up letters and calls. To vote, you may use any of the following methods: - BY MAIL. Please complete, date and sign your proxy card and mail it in the enclosed postage paid envelope. Votes must be received prior to March 19, 2004. - BY INTERNET. Have your proxy card available. Go to the web site: www.proxyvote.com. Enter your 12-digit control number from your proxy card.

Rice PRESIDENT <Page> IMPORTANT INFORMATION TO HELP YOU UNDERSTAND AND VOTE ON THE PROPOSAL Please read the enclosed proxy statement and prospectus for a complete description of the proposal. As a quick reference, the following provides a brief overview of the proposal. Q&A: QUESTIONS AND ANSWERS WHAT PROPOSAL AM I BEING ASKED TO VOTE ON? Shareholders of Treasury Series are being asked to approve a transaction between Treasury Series and Money Market Series. When we refer to the "transaction," we mean the transfer of all of the assets of Treasury Series to, and the assumption of all of its liabilities by, Money Market Series, in exchange for shares of Money Market Series, and the subsequent cancellation of shares of Treasury Series. WHAT IS THE REASON FOR THIS TRANSACTION? Historically, most assets invested in Treasury Series and some assets invested in Money Market Series were "sweep" cash assets maintained in customer brokerage accounts offered by Prudential Securities Incorporated (PSI). Last year, PSI was effectively acquired by Wachovia Securities LLC (Wachovia), and PSI became a division of Wachovia. Effective as of November 10, 2003, Wachovia decided that it would no longer offer Treasury Series and Money Market Series as investment options for sweep cash assets maintained in former PSI customer brokerage accounts, and instead sweep assets would be deposited into bank accounts offered through Wachovia. Pursuant to this process, all new cash assets that are deposited into Wachovia brokerage accounts will be deposited into the bank accounts. Existing cash assets maintained in the brokerage accounts that are presently invested in Treasury Series and Money Market Series will be transferred and deposited in the bank accounts in a gradual process over the next several months, as Wachovia brokerage customers redeem Treasury Series and Money Market Series shares. Because the majority of the assets invested in Treasury Series are sweep assets, the decision by Wachovia to discontinue offering Treasury Series as an investment option is expected to result in a significant increase in the expenses of Treasury Series, due to the anticipated decrease in the assets of Treasury Series. The decision by Wachovia to discontinue offering Money Market Series as an investment option is also expected to result in an increase in the expenses of Money Market Series; however, because the amount of sweep assets invested in Money Market Series relative to total assets is considerably smaller than the amount of sweep assets invested in Treasury Series, the increase in operating expenses resulting from the redemption of sweep assets from Money Market Series is not expected to be as great as the increase in operating expenses resulting from the redemption of sweep assets from Treasury Series. If approved, the transaction will reduce the amount of the anticipated increase in fund expenses resulting from Wachovia's discontinuance of its offering of Treasury Series as a sweep option, but even if the transaction is approved, the expenses borne by the remaining shareholders of Treasury Series as shareholders of Money Market Series will still be higher than current fund expense levels. DO TREASURY SERIES AND MONEY MARKET SERIES HAVE SIMILAR INVESTMENT POLICIES? Yes. The investment objectives and policies of Treasury Series and Money Market Series (each, a Series) are similar. Both Treasury Series and Money Market Series are money market funds. Money market funds hold high-quality short-term debt obligations. The investment objectives of Treasury Series and Money Market Series are substantially identical. The investment objective of Treasury Series is high current income consistent with the preservation of principal and liquidity. The investment objective of Money Market Series is high current income, preservation of capital and maintenance of liquidity. To achieve its objective, Treasury Series invests exclusively in U.S. Treasury obligations that mature in 13 months or less. To achieve its objective, Money Market Series invests, under normal circumstances, at least 80% of its investable assets in U.S. Government securities. <Page> After the proposed transaction is consummated, it is expected that the combined fund will be managed according to the investment objective and policies of Money Market Series. WHO ARE THE MANAGERS FOR THESE SERIES? Prudential Investments LLC (PI) currently provides investment advisory services for each of the Series. Prudential Investment Management, Inc. (PIM) is the subadviser for each Series. PIM is an affiliate of PI. The Money Markets Team of PIM, headed by Joseph Tully, is responsible for overseeing the day-to-day management of each Series. HOW DO THE EXPENSE STRUCTURES OF THE SERIES COMPARE? Treasury Series has two classes of stock outstanding: Class A shares and Class Z shares (Treasury Series is also authorized to issue Class S shares, but no Class S shares are outstanding). Money Market Series has two classes of stock outstanding: Class A shares and Class Z shares. The following table compares the expenses incurred by Class A shares and Class Z shares of stock for each of the two Series.

Each Series has experienced substantially similar performance over the past five years. The table below compares the annual returns of the Class A shares of each Series over the past five calendar years: <Table> <Caption> CALENDAR YEAR SERIES ANNUAL RETURNS - ------------- ------------- -------------- 2002 Treasury 1.25% Money Market 1.13% 2001 Treasury 3.57% Money Market 3.58% 2000 Treasury 5.38% Money Market 5.53% 1999 Treasury 4.25% Money Market 4.36% 1998 Treasury 4.61% Money Market 4.82% </Table> <Page> For more performance information, please see pages 11 and 12 of the proxy statement and prospectus. IS THE TRANSACTION A TAXABLE EVENT FOR FEDERAL INCOME TAX PURPOSES? We expect that the exchange of shares pursuant to the transaction will not result in taxable gain or loss for U.S. federal income tax purposes. For more information, see the proxy statement and prospectus. WHAT WILL BE THE ANTICIPATED SIZE OF MONEY MARKET SERIES AFTER THE TRANSACTION? If the proposal is approved, based on information available as of November 30, 2003, Money Market Series is anticipated to have approximately $441 million in assets, which includes the anticipated redemption of customer brokerage "sweep" assets by Wachovia. HOW WILL YOU DETERMINE THE NUMBER OF SHARES OF MONEY MARKET SERIES THAT I WILL RECEIVE? As of the close of business of the New York Stock Exchange on the date the transaction is consummated, shareholders will receive the number of full and fractional Class A and Class Z shares of Money Market Series that is equal in value to the net asset value of their Class A or Class Z shares of Treasury Series, as applicable, on that date. The transaction is anticipated to occur as soon as practicable following shareholder approval. WHAT IF THERE ARE NOT ENOUGH VOTES TO REACH QUORUM BY THE SCHEDULED SHAREHOLDER MEETING DATE? If we do not receive sufficient votes to hold the Meeting, we or Georgeson Shareholder Communications Inc., a proxy solicitation firm, may contact you by mail or telephone to encourage you to vote. Shareholders should review the proxy materials and cast their vote to avoid additional mailings or telephone calls. If there are not sufficient votes to approve the proposal by the time of the Meeting (March 19, 2004), the Meeting may be adjourned to permit further solicitation of proxy votes. HAS THE BOARD OF TRUSTEES APPROVED THE PROPOSAL? Yes. The Board of Trustees of Government Securities Trust has approved the proposal and recommends that you vote for the proposal. WHAT HAPPENS IF THE PROPOSAL IS NOT APPROVED? If shareholders of Treasury Series do not approve the proposal, or if the transaction is not completed, they will continue to be shareholders of Treasury Series and the Board of Trustees will consider other possible courses of action, including resubmitting the proposal to shareholders, or liquidating Treasury Series. HOW MANY VOTES AM I ENTITLED TO CAST? As a shareholder, you are entitled to one vote for each share you own of Treasury Series on the record date. The record date is December 19, 2003. HOW DO I VOTE MY SHARES? You can vote your shares by completing and signing the enclosed proxy card, and mailing it in the enclosed postage paid envelope.

The purpose of the Meeting is described in the accompanying Notice of Special Meeting of Shareholders (Notice). The solicitation is made primarily by the mailing of the Notice, this Proxy Statement and the accompanying proxy card on or about February , 2004. Supplementary solicitations may be made by mail, telephone, facsimile, electronic means or by personal interview by representatives of Treasury Series. In addition, Georgeson Shareholder Communications Inc., a proxy solicitation firm, may be retained to solicit shareholders on behalf of Treasury Series. The costs of retaining Georgeson Shareholder Communications Inc. and the expenses in connection with preparing this Proxy Statement and its enclosures will be borne pro rata by each Series. The anticipated cost of the solicitation, including the expenses incurred in connection with preparing this Proxy Statement and its enclosures, is approximately $ . Even if you sign and return the enclosed proxy card, you may revoke your proxy at any time prior to its use by written notification received by Treasury Series, by submitting a later-dated proxy card, or by attending the Meeting and voting in person. All proxy cards solicited by the Board of Trustees that are properly completed and received by Treasury Series prior to the Meeting, and that are not revoked, will be voted at the Meeting. Shares represented by proxies will be voted in accordance with the instructions you provide. If no instruction is made on a properly completed proxy card, it will be voted FOR the proposal. If a proxy that is properly signed and returned is accompanied by instructions to withhold authority to vote (an abstention) or represents a broker "non-vote" (that is, a proxy from a broker or nominee indicating that they have not received instructions from the beneficial owner or other person entitled to vote shares on this matter for which the broker or nominee does not have discretionary power), the shares represented thereby will be considered present for purposes of determining the existence of a quorum for the transaction of business but, because the proposal requires approval by a majority of the outstanding voting securities (as defined by the Investment Company Act of 1940, as amended) of Treasury Series, will have the effect of a vote AGAINST the proposal. Treasury Series also may arrange to have votes recorded by telephone. If Treasury Series takes votes by telephone, it will use procedures designed to authenticate shareholders' identities, to allow shareholders to authorize the voting of their shares in accordance with their instructions, and to confirm that their 3 <Page> instructions have been properly recorded. Proxies given by telephone may be revoked at any time before they are voted in the same manner that proxies voted by mail may be revoked. Shareholders may also cast their vote via the internet. The internet voting procedures have been designed to authenticate shareholders' identities, to allow shareholders to authorize the voting of their shares in accordance with their instructions, and to confirm that shareholders' instructions have been recorded properly. We have been advised that the internet voting procedures are consistent with the requirements of applicable law. Shareholders voting via the internet should understand that there may be costs associated with electronic access, such as usage charges from an Internet access provider and telephone companies, that must be borne by the shareholder. To vote via the Internet, shareholders should have their proxy card available and go to the web site: www.proxyvote.com and enter the 12-digit control number appearing on the proxy card. Shareholders should then follow the instructions found on the web site. Proxies given by internet may be revoked at any time before they are voted in the same manner that proxies voted by mail may be revoked. If a quorum is not present at the Meeting, or if a quorum is present at the Meeting but sufficient votes to approve the proposal are not received, or if other matters arise requiring shareholder attention, the persons named as proxy agents may propose one or more adjournments of the Meeting to permit the further solicitation of proxies. The presence in person or by proxy of 40% or more of the shares entitled to vote on matters for Treasury Series constitutes a quorum for Treasury Series. An adjournment of the Meeting will require the affirmative vote of a majority of shares of Treasury Series present in person at the Meeting or represented by proxy. When voting on a proposed adjournment, the persons named as proxy agents will vote FOR the proposed adjournment all shares that they are entitled to vote with respect to the proposal, unless directed to vote AGAINST the proposal, in which case such shares will be voted against the proposed adjournment. Shares represented by abstentions or broker "non-votes" will not be voted for or against an adjournment. Because an adjournment requires an affirmative vote of a majority of shares present, abstentions and broker "non-votes" will have the effect of a vote against adjournment. A shareholder vote may be taken on the proposal described in this Proxy Statement or on any other business properly presented at the Meeting prior to adjournment if sufficient votes have been received. Shareholders of record at the close of business on December 19, 2003 (the Record Date) of Treasury Series will be entitled to vote at the Meeting. Each such shareholder will be entitled to one vote for each share of Treasury Series held on that date (fractional shares will be entitled to a proportionate fractional vote). On the Record Date, there were shares issued and outstanding, including Class A shares and Class Z shares of Treasury Series. The following shareholders held 5% or more of any class of shares of Treasury Series on December 19, 2003: <Table> <Caption> NAME ADDRESS CLASS SHARES/% ---- ------- -------- ---------------- James W Gill Jr and P O Box 1331 A 39,565/8.1% Joanne G Gill JT WROS Keystone Heights FL 32656 Wilson C Swigart, 1860 Saddle Hill Rd S A 56,937/11.6% Stephen B Swigart & Dunedin FL 34698 Betty C Hornbrook CO-TTEES M J Swigart Trust UA DTD 06/28/85 Wachovia Securities 4 Salt Meadow Court A 33,655/6.9% Vera Esposito Bayport NY 11705 IRA DTD 09/09/86 Prudential Trust Company 216 Windsor Dr A 52,354/10.7% C/F The IRA Of Gerald G Martin Warner Robins GA 31088 </Table> 4 <Page> <Table> <Caption> NAME ADDRESS CLASS SHARES/% ---- ------- -------- ---------------- Gail D Sturgeon Trust 5657 Colton Blvd A 65,034/13.2% Gail D Sturgeon TTEE Oakland CA 94611 DTD 09/18/90 Prudential Trust Company Attn: PMFS Coordinator Z 7,535,219/99.9% FBO Pru-DC Trust Accounts 30 Scranton Office Park Moosic PA 18507 American Life & Accident Attn: Dinwiddie Lampton Jr AX 13,906,942/16.0% Insurance Co Of Kentucky 3 Riverfront Plaza Louisville KY 40202 Hardscuffle Inc Attn: Dinwiddie Lampton Jr AX 5,964,547/6.8% 3 Riverfront Plaza Louisville KY 40202 </Table> The following shareholders held 5% or more of any class of shares of Money Market Series on December 19, 2003: <Table> <Caption> NAME ADDRESS CLASS SHARES/% ---- ------- -------- ----------------- Pru Defined Contribution Svs Attn: PMFS Coordinator Direct 63,525,156/15.8% FBO Pru-Non-Trust Accounts 30 Scranton Office Park Moosic PA 18507 Prudential Trust Company Attn: PMFS Coordinator Direct 147,681,983/36.6% FB Pru-DC Trust Accounts 30 Scranton Office Park Moosic PA 18507 Pru Defined Contribution Svs Attn: PMFS Coordinator A 8,039,421/27.0% FBO Pru-Non-Trust Accounts 30 Scranton Office Park Moosic PA 18507 Prudential Trust Company Attn: PMFS Coordinator A 14,253,848/47.9% FBO Pru-DC Trust Accounts 30 Scranton Office Park Moosic PA 18507 Mr Paul Rossi 454 Hasbrouck Blvd B 74,314/13.3% Oradell NJ 07649 Delaware Charter T/F PO Box 691 B 36,340/6.5% Mr Michael S Lebowitz PS Plan Carmel CA 93921 DTD 09/27/83 Robert Wilson 130-15 224 St B 47,787/8.6% Laurelton NY 11413 Pru Defined Contributions Svcs Attn: PMFS Coordinator Z 8,632,176/39.3% FBO Pro-Non-Trust Accounts 30 Scranton Office Park Moosic PA 18507 Prudential Trust Company Attn: PMFS Coordinator Z 13,313,684/60.1% FB Pru-DC Trust Accounts 30 Scranton Office Park Moosic PA 18507 </Table> As of December 19, 2003, the Trustees and officers of Treasury Series and Money Market Series owned, in the aggregate, less than 1% of each class of each Series' total outstanding shares. 5 <Page> VOTE REQUIRED APPROVAL OF THE TRANSACTION REQUIRES THE AFFIRMATIVE VOTE OF A MAJORITY OF THE OUTSTANDING VOTING SECURITIES OF TREASURY SERIES, WHICH MEANS THE LESSER OF (I) 67% OF SUCH SHARES PRESENT AT THE MEETING IF THE OWNERS OF MORE THAN 50% OF THE SHARES OF TREASURY SERIES THEN OUTSTANDING ARE PRESENT IN PERSON OR BY PROXY, OR (II) MORE THAN 50% OF THE OUTSTANDING SHARES OF TREASURY SERIES, WITHOUT REGARD TO CLASS. APPROVAL OF THE TRANSACTION SYNOPSIS The following is a summary of information contained elsewhere in this Proxy Statement, the Plan (the form of which is attached as Attachment A), and in the Prospectuses and Statements of Additional Information, as supplemented to date, of Treasury Series and Money Market Series which are incorporated into this Proxy Statement by this reference, and is qualified in its entirety by reference to these documents. Shareholders should read this Proxy Statement and the Prospectuses and Statements of Additional Information, as supplemented to date, of both Series for more complete information. Under the Plan, Treasury Series will transfer all of its assets to, and all of its liabilities will be assumed by, Money Market Series, a mutual fund also managed by Prudential Investments LLC (PI), in exchange for shares of Money Market Series. The outstanding shares of Treasury Series will be cancelled and current shareholders of Treasury Series will become shareholders of Money Market Series. INVESTMENT OBJECTIVES AND POLICIES Treasury Series and Money Market Series each have similar investment objectives and policies. The investment objective of Treasury Series is high current income consistent with the preservation of principal and liquidity. The investment objective of Money Market Series is high current income, preservation of capital and maintenance of liquidity. Treasury Series seeks to achieve its investment objective by investing exclusively in U.S. Treasury obligations that mature in 13 months or less. Money Market Series seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its investable assets (net assets plus any borrowings for investment purposes) in U.S. Government securities, including repurchase agreements with respect to such securities. The principal type of security in which both Treasury Series and Money Market Series invest are short-term money market instruments. While Treasury Series may only invest in U.S. Treasury obligations that mature in 13 months or less, Money Market Series may also invest in debt obligations issued or guaranteed by the U.S. Government or its agencies or instrumentalities. Both Treasury Series and Money Market Series may also invest in floating rate debt securities, variable rate debt securities, as well as when-issued and delayed delivery securities. In addition, Money Market Series may also invest in asset-backed securities and liquidity puts and calls. After the transaction is completed it is expected that the combined fund will be managed according to the investment objective and policies of Money Market Series. The benchmark index for both Treasury Series and Money Market Series is the iMoneyNet Money Fund Report Average, which for Treasury Series is an average based upon the average yield of all mutual funds in the iMoneyNet MFR Average/U.S. Treasury retail fund category, and for Money Market Series is an average based upon the average yield of all mutual funds in the iMoneyNet MFR Average/All Taxable money market fund category. Treasury Series and Money Market Series are each managed by Prudential Investments LLC (PI). The address of PI is Gateway Center Three, 100 Mulberry Street, 14th Floor, Newark, New Jersey 07102-4077. PI and its predecessors have served as manager or administrator to investment companies since 1987. As of 6 <Page> September 30, 2003, PI served as manager to all of the JennisonDryden and Strategic Partners Mutual Funds, and as manager or administrator to closed-end investment companies, with aggregate assets of approximately $ billion. Treasury Series and Money Market Series typically distribute all or substantially all of their ordinary income and net realized capital gains annually. INVESTMENT ADVISORY SERVICES Under a management agreement with Government Securities Trust, PI currently provides investment advisory services for Treasury Series and Money Market Series. Each Series has the same subadviser, Prudential Investment Management, Inc. (PIM). The PIM Fixed Income Group, headed by Joseph Tully, manages the portfolios of Treasury Series and Money Market Series. For more information about the subadvisers or portfolio managers, see the Prospectuses of the relevant Series. The other service providers to the Series are not expected to change as a result of the proposed transaction. EXPENSE STRUCTURES Government Securities Trust, on behalf of Treasury Series and Money Market Series pays monthly management fees to PI for managing each Series. PI, in turn, pays out of its management fee a fee to PIM for providing advisory services to the Series. Government Securities Trust, on behalf of Treasury Series, has agreed to pay PI a management fee at an annual rate of .40 of 1% of average daily net assets. Government Securities Trust, on behalf of Money Market Series, has agreed to pay PI a management fee at an annual rate of .40 of 1% of average daily net assets up to $1 billion; .375 of 1% on assets between $1 billion and $1.5 billion and .35 of 1% on assets in excess of $1.5 billion. For the fiscal year ended November 30, 2003, Treasury Series and Money Market Series each paid PI a management fee of .40 of 1% of average daily net assets. The management fee paid by Money Market Series is not expected to change if the transaction is approved by shareholders. The management fee paid by each Series covers PI's oversight of each Series' investment portfolios. PI also administers each Series' corporate affairs and, in connection therewith, furnishes Government Securities Trust and its Series with office facilities, together with those ordinary clerical and bookkeeping services that are not furnished by Government Securities Trust's custodian or transfer and dividend disbursing agent. Officers and employees of PI serve as officers and Trustees of Government Securities Trust without compensation. PURCHASES, REDEMPTIONS, EXCHANGES AND DISTRIBUTIONS Each Series currently has the same policies with respect to purchasing shares, redeeming or exchanging shares, and distributions. For more information regarding the Series' policies, see "Purchases, Redemptions, Exchanges and Distributions" below. TAX CONSIDERATIONS For federal income tax purposes, in the opinion of counsel, no gain or loss will be recognized by the shareholders of Treasury Series as a result of the transaction. For a more detailed discussion of the federal income tax consequences, see "U.S. Federal Income Tax Considerations" below. APPRAISAL RIGHTS Shareholders of Treasury Series do not have appraisal rights under Massachusetts law in connection with the transaction. Shareholders of Treasury Series may, however, redeem their shares at net asset value prior to the date of the proposed transaction. 7 <Page> POTENTIAL BENEFITS FROM TRANSACTION Overall, the proposed transaction would provide shareholders of Treasury Series with the following potential benefits: - investment in a fund with an investment objective and policies similar to the investment objectives and policies of Treasury Series; and - a reduction in the amount of the anticipated increase in expenses that will be borne by remaining Treasury Series shareholders following the redemption of sweep assets from Treasury Series by Wachovia Securities LLC (Wachovia Securities) during 2004. THE BOARD OF TRUSTEES OF GOVERNMENT SECURITIES TRUST BELIEVES THAT THE TRANSACTION WILL BENEFIT SHAREHOLDERS OF TREASURY SERIES, AND RECOMMENDS THAT SHAREHOLDERS VOTE IN FAVOR OF THE TRANSACTION. THE PROPOSED TRANSACTION Shareholders of Treasury Series will be asked at the Meeting to vote upon and approve the Plan under which Treasury Series will transfer all of its assets to, and all of its liabilities will be assumed by, Money Market Series, whereupon Money Market Series will be the surviving mutual fund. Each whole and fractional share of each class of Treasury Series will be exchanged for whole and fractional shares of equal net asset value of the same class of Money Market Series, and outstanding shares of Treasury Series will be cancelled, on or about the Effective Time. Approval of the transaction will be determined by approval of the shareholders of Treasury Series. No vote by shareholders of Money Market Series is required. The Plan provides that it is a condition to complete the transaction that Government Securities Trust will have received an opinion of counsel to the effect that the transaction will not result in any taxable gain or loss for U.S. federal income tax purposes to Treasury Series or Money Market Series or to the shareholders of any of the Series. SERIES OPERATING EXPENSES Each Series pays a management fee to PI for managing its investments and business affairs which is calculated and paid to PI every month. Government Securities Trust, on behalf of Treasury Series, has agreed to pay PI a management fee at an annual rate of .40 of 1% of average daily net assets. Government Securities Trust, on behalf of Money Market Series, has agreed to pay PI a management fee at an annual rate of .40 of 1% of average daily net assets up to $1 billion; .375 of 1% on assets between $1 billion and $1.5 billion and ..35 of 1% on assets in excess of $1.5 billion. For the fiscal year ended November 30, 2003, Treasury Series and Money Market Series each paid PI a management fee of .40 of 1% of average daily net assets. The management fee paid by Money Market Series is not expected to change if the transaction is approved by shareholders. In addition to the management fee, each Series incurs other expenses for services such as maintaining shareholder records and furnishing shareholder statements and financial reports. For the fiscal year ended November 30, 2003, Treasury Series' annualized total operating expense ratio for Class A shares was 0.63%, and for Class Z shares was 0.50%. For the fiscal year ended November 30, 2003, Money Market Series' annualized total operating expense ratios for Class A shares was 0.77%, and for Class Z shares was 0.64%. If shareholders of Treasury Series approve the transaction, Money Market Series' expense structure will apply. However, as further discussed below, due to the anticipated redemption of all sweep assets from Treasury Series and Money Market Series by Wachovia Securities, it is expected that the annualized total operating expense ratios for each share class of Treasury Series and each share class of Money Market Series will significantly increase from current levels, even if shareholders of Treasury Series approve the proposed transaction. If shareholders of Treasury Series approve the transaction, it is expected that the shareholders of Treasury Series will experience a lesser expense increase than would otherwise occur as a result of the redemptions by Wachovia. 8 <Page> See "-- Operating Expense Tables" below for estimates of expenses if the transaction is approved. SHAREHOLDER FEES The following table shows the shareholder fees that are imposed on new purchases or redemptions of shares of Money Market Series that are the same as the shareholder fees imposed on new purchases of Treasury Series. These fees will not be imposed on new shares of Money Market Series that are acquired pursuant to the transaction.

THE PRO FORMA FEES AND EXPENSES SHOWN IN THE FOLLOWING TABLES ASSUME THAT SHAREHOLDERS OF TREASURY SERIES APPROVE THE TRANSACTION. THE PRO FORMA FEES AND EXPENSES SHOWN IN THE FOLLOWING TABLES DO NOT REFLECT THE IMPACT OF THE ANTICIPATED REDEMPTION OF SWEEP ASSETS BY WACHOVIA SECURITIES. IF THE PRO FORMA FEES AND EXPENSES SHOWN IN THE FOLLOWING TABLES REFLECTED THE IMPACT OF THE REDEMPTION OF SWEEP ASSETS BY WACHOVIA SECURITIES, THE PRO FORMA FEES AND EXPENSES WOULD BE HIGHER. SEE "ANTICIPATED IMPACT OF THE WACHOVIA REDEMPTIONS" BELOW FOR ADDITIONAL INFORMATION. 9 <Page> Series operating expenses are paid out of each Series' assets. Expenses are factored into each Series' share price or dividends and are not charged directly to shareholder accounts. The following figures are based on historical expenses of Treasury Series and Money Market Series as of November 30, 2003.

These examples illustrate the effect of expenses, but are not meant to suggest actual or expected expenses, which may vary. The assumed return of 5% is not a prediction of, and does not represent, actual or expected performance of either Series. 10 <Page> PRO FORMA CAPITALIZATION The following table shows the capitalization of Treasury Series and Money Market Series as of November 30, 2003 and the pro forma Combined Money Market Series capitalization as if the transaction had occurred on that date. <Table> <Caption> PRO FORMA COMBINED TREASURY SERIES MONEY MARKET SERIES MONEY MARKET SERIES --------------- ------------------- ------------------- Net Assets (000s) Class A.................................. $343,477 $504,806 $504,806 Class Z.................................. $ 5,846 $ 22,486 $ 22,486 Net Asset Value Per Share Class A.................................. $ 1.00 $ 1.00 $ 1.00 Class Z.................................. $ 1.00 $ 1.00 $ 1.00 Shares Outstanding (000s) Class A.................................. 343,477 504,806 504,806 Class Z.................................. 5,846 22,486 22,486 </Table> ANTICIPATED IMPACT OF THE WACHOVIA REDEMPTIONS Currently, approximately 82% of the assets invested in Treasury Series are "sweep" assets invested by brokerage customers of Wachovia Securities through their brokerage accounts. "Sweep" assets represent cash balances held in customer brokerage accounts that are "swept" out of each customer's brokerage account and invested in a designated investment option. Historically, Treasury Series was one of the designated investment options available to brokerage customers for investment of their sweep assets. Effective as of November 10, 2003, Wachovia Securities discontinued offering Treasury Series and Money Market Series as available investment options for the investment of sweep assets by their brokerage customers. Instead, Wachovia Securities has elected to direct all sweep assets into bank accounts offered through Wachovia. Due to Wachovia's decision to discontinue Treasury Series and Money Market Series as investment options, it is expected that by early 2004, virtually all sweep assets which are currently invested in each Series will have been redeemed. Because sweep assets comprise the majority of the overall assets of Treasury Series, it is anticipated that the operating expenses of Treasury Series after all sweep assets are redeemed will be significantly higher than the current operating expenses of Treasury Series. Although Wachovia Securities has also discontinued Money Market Series as an available investment option for the investment of sweep assets by their brokerage customers, because the amount of sweep assets invested in Money Market Series relative to total assets (currently, approximately 29%) is considerably smaller than the amount of sweep assets invested in Treasury Series, the increase in operating expenses resulting from the redemption of sweep assets from Money Market Series is not expected to be as great as the increase in operating expenses resulting from the redemption of sweep assets from Treasury Series. The proposed transaction WILL NOT RESULT IN A REDUCTION OF CURRENT EXPENSES FOR SHAREHOLDERS OF TREASURY SERIES, because the expected expense increase resulting from the Wachovia redemptions is expected to be greater than the expected expense reduction derived from combining the assets of Treasury Series and Money Market Series. However, because the proposed transaction, if approved, will combine the remaining non-sweep assets of Treasury Series and Money Market Series, it is expected that shareholders of Treasury Series will experience a lesser expense increase than would otherwise result from the Wachovia redemptions. Due to the impact of the Wachovia redemptions, it is expected that by early 2004, virtually all Wachovia sweep assets will have been redeemed, and the operating expenses borne by shareholders of Treasury Series will increase, even if the proposed transaction is approved. 11 <Page> The table below illustrates the expected impact on the operating expenses of Class A shares of Treasury Series resulting from the Wachovia redemptions if the transaction is approved: <Table> <Caption> ANTICIPATED TREASURY SERIES OPERATING ANTICIPATED MONEY EXPENSES AFTER MARKET SERIES REMOVAL OF "SWEEP" OPERATING EXPENSES BENEFIT IN EXPENSES TO CURRENT TREASURY ASSETS (DOES NOT AFTER REMOVAL OF TREASURY SERIES SERIES OPERATING REFLECT IMPACT OF CHANGE IN EXPENSES TO "SWEEP" ASSETS AND SHAREHOLDERS IF EXPENSES (AS OF CONSUMMATION OF TREASURY SERIES CONSUMMATION OF TRANSACTION IS OCT. 31, 2003) TRANSACTION) SHAREHOLDERS TRANSACTION CONSUMMATED - --------------------- -------------------- --------------------- -------------------- ---------------------- 0.61% 0.91% +0.30% 0.85% -0.06% </Table> The table below illustrates the expected impact on the operating expenses of Class A shares of Money Market Series resulting from the Wachovia redemptions if the transaction is approved: <Table> <Caption> ANTICIPATED MONEY MARKET SERIES ANTICIPATED MONEY OPERATING EXPENSES MARKET SERIES AFTER REMOVAL OF OPERATING EXPENSES BENEFIT IN EXPENSES TO "SWEEP" ASSETS (DOES AFTER REMOVAL OF MONEY MARKET SERIES NOT REFLECT IMPACT OF "SWEEP" ASSETS AND SHAREHOLDERS IF CONSUMMATION OF CONSUMMATION OF TRANSACTION IF TRANSACTION) TRANSACTION CONSUMMATED - ---------------------- -------------------- ---------------------- 0.87% 0.85% -0.02% </Table> PERFORMANCE COMPARISONS OF THE SERIES The following tables compare each Series' average annual total returns and annual returns for the periods set forth below.

The following information compares the investment objectives and policies of the Series. INVESTMENT OBJECTIVES Treasury Series' investment objective is high current income consistent with the preservation of principal and liquidity. Money Market Series' investment objective is high current income, preservation of capital and maintenance of liquidity. The investment objective of each Series is a fundamental policy. This means that the objective cannot be changed without the approval of shareholders of the relevant Series. There can be no assurance that either Series achieve its objective. With the exception of fundamental policies, investment policies (other than specified investment restrictions) of the Series can be changed without shareholder approval. PRINCIPAL INVESTMENT STRATEGIES Both Treasury Series and Money Market Series are money market funds with substantially identical investment objectives, and they seek to achieve their investment objectives through similar, but not identical investment strategies. Treasury Series seeks to achieve its investment objective by investing exclusively in U.S. Treasury obligations that mature in 13 months or less. Money Market Series seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its investable assets in short-term money market instruments issued or guaranteed by the U.S. government or its agencies or instrumentalities. Each of the Series may also use certain investment strategies to increase the Series' returns or protect its assets. Treasury Series may invest in floating rate debt securities and variable rate debt securities, as well as when-issued and delayed delivery securities. Money Market Series may invest in asset-backed securities, floating rate debt securities, variable rate debt securities, when-issued and delayed delivery securities and liquidity puts and calls. COMPARISON OF OTHER POLICIES OF THE SERIES INVESTMENT RESTRICTIONS Treasury Series and Money Market Series have substantially similar fundamental investment restrictions. COMPARISON OF PRINCIPAL RISK FACTORS Both Series are money market funds, which are intended to provide investors with a lower risk, highly liquid investment option. Although each Series attempts to maintain a net asset value of $1 per share, there can be no guarantee that either Series will always be able to do so. It is possible that a shareholder investing in either Series could lose money. The money market securities in which Treasury Series invests are generally subject to the risk that the obligations could lose value if interest rates rise or there is a lack of investor confidence in the borrower. In addition, certain securities in which Treasury Series may invest may be subject to the risk that the issuer may be unable to make principal and interest payments when they are due. The money market securities in which Money Market Series may invest are also subject to the risk that the obligations could lose value if interest rates rise or there is a lack of investor confidence in the borrower. In addition, certain securities in which Money Market Series may invest may be subject to the risk that the issuer may be unable to make principal and interest payments when they are due. 14 <Page> As described above, each Fund has similar investment objectives, policies and permissible investments. Like any mutual fund, an investment in either Treasury Series or Money Market Series could lose value. For a more complete discussion of the risks associated with any of these Series, please refer to the "Risk/Return Summary" or the section entitled "Investment Risks" in each Series' Prospectus. OPERATIONS OF MONEY MARKET SERIES FOLLOWING THE TRANSACTION Neither PI nor PIM expects Money Market Series to revise its investment policies as a result of the transaction. Neither PI nor PIM anticipate any significant changes to Money Market Series' management or general investment approach. The agents that provide Money Market Series with services, such as its Custodian and Transfer Agent, which also provide these services to Treasury Series, are not expected to change. All of the current investments of Treasury Series are permissible investments for Money Market Series. Nevertheless, PI may sell securities held by Treasury Series or PIM may sell securities held by Money Market Series between shareholder approval and the Effective Time of the transaction as may be necessary or desirable in the ongoing management of each Series and the adjustment of each Series' portfolio in anticipation of the merger. Transaction costs associated with such adjustments will be borne by the Series that incurred them. Transaction costs associated with such adjustments that occur after the Effective Time will be borne by Money Market Series. PURCHASES, REDEMPTIONS, EXCHANGES AND DISTRIBUTIONS PURCHASING SHARES The price to buy one share of a class of each Series is that class's net asset value, or NAV. Each Series offers Class A and Class Z shares. Shares in the Series are purchased at the next NAV calculated after your investment is received and accepted, plus any applicable sales charge. Each Series' NAV is normally calculated once each business day as of the close of regular trading on the New York Stock Exchange (usually, 4:00 p.m., New York time). Refer to each Series' Prospectus for more information regarding how to buy shares. REDEEMING SHARES Your shares will be sold at the next NAV determined after your order to sell is received. Refer to each Series' Prospectus for more information regarding how to sell shares. MINIMUM INVESTMENT REQUIREMENTS For each Series, the minimum initial investment amount is $1,000 for Class A shares. There is no minimum initial investment amount for Class Z shares, although Class Z shares are available only to a limited group of investors. Refer to each Series' Prospectus for more information regarding eligibility to purchase Class Z shares. PURCHASES AND REDEMPTIONS OF TREASURY SERIES At the close of business on November 19, 2003, Treasury Series closed to new accounts pending the transaction with Money Market Series. Shareholders of Treasury Series may redeem shares through the Effective Time of the transaction. If the transaction is approved, the purchase and redemption policies will be the same as the applicable policies of Money Market Series. 15 <Page> EXCHANGES OF SERIES SHARES The exchange privilege currently offered by Treasury Series is the same as for Money Market Series and is not expected to change after the transaction. Shareholders of the Series may exchange their shares for shares of any other JennisonDryden or Strategic Partners Mutual Funds. Refer to each Series' Prospectus for restrictions governing exchanges. DIVIDENDS AND OTHER DISTRIBUTIONS Both Series distribute substantially all of their net investment income and net capital gains to shareholders each year. Both Series declare dividends, if any, annually. At or before the Effective Time, Treasury Series shall declare additional dividends or other distributions in order to distribute substantially all of its investment income and realized capital gains for its taxable year ending upon completion of the transaction. THE PROPOSED TRANSACTION PLAN OF REORGANIZATION The Plan describes the terms and conditions under which the proposed transaction may be completed. Significant provisions of the Plan are summarized below; however, this summary is qualified in its entirety by reference to the Plan, the form of which is attached as Attachment A to this Proxy Statement. The Plan contemplates that Treasury Series will transfer all of its assets to, and all of its liabilities will be assumed by, Money Market Series at the Effective Time and Money Market Series will be the surviving Series. Each whole and fractional Class A share of Treasury Series will be exchanged for whole and fractional Class A shares of equal net asset value of Money Market Series. Each whole and fractional Class Z share of Treasury Series will be exchanged for whole and fractional Class Z shares of equal net asset value of Money Market Series. If requested, Money Market Series will issue certificates representing its shares, but only upon surrender of certificates for shares of Treasury Series. Immediately after the closing of the transaction, each former Treasury Series shareholder will own shares of Money Market Series equal to the aggregate net asset value of that shareholder's shares of Treasury Series immediately prior to the closing of the transaction. The net asset value per share of Money Market Series will not be affected by the transaction. Thus, the transaction will not result in a dilution of the pecuniary interests of shareholders of either Series. However, the transaction will reduce the percentage ownership of each Series' shareholders below such shareholder's current percentage of ownership in either Series. All assets, rights, privileges, powers and franchises of Treasury Series, and all debts due on whatever account to it, shall be taken and deemed to be transferred to and vested in Money Market Series without further act or deed, and all such assets, rights, privileges, powers and franchises, and all and every other interest of Treasury Series, shall be thereafter effectively the property of Money Market Series as they were of Treasury Series. Money Market Series generally will be responsible for all of the liabilities and obligations of Treasury Series. The value of the assets and liabilities of Treasury Series will be determined at the Effective Time, using the valuation procedures set forth in the Prospectus and Statement of Additional Information for Treasury Series. The net asset value of a share of Money Market Series will be determined as of the same time using the valuation procedures set forth in its Prospectus and Statement of Additional Information. Any transfer taxes payable upon issuance of shares of Money Market Series in a name other than that of the registered holder of the shares on the books of Treasury Series, as of that time, will be payable by the person to whom such shares are to be issued as a condition of such transfer. 16 <Page> The completion of the transaction is subject to a number of conditions set forth in the Plan. In addition, the Plan may be amended, except that no amendment that may have a materially adverse effect on the shareholders' interests may be made subsequent to the Meeting. REASONS FOR THE TRANSACTION The Board of Trustees (the Board) of Government Securities Trust has determined that the transaction is in the best interests of the shareholders of Treasury Series and that the transaction will not result in a dilution of the pecuniary interests of shareholders of Treasury Series. In considering the transaction, the Board considered a number of factors that it believes benefits the shareholders of Treasury Series. The Board considered that, following the transaction, the shareholders of Treasury Series will remain invested in a money market mutual fund which has the same, or similar investment objective, policies and restrictions, and similar investment techniques. The Board also considered the fact that the performance histories of Treasury Series and Money Market Series are substantially similar. The Board also considered that, because of the expected increase in expenses to shareholders resulting from the redemption of sweep assets by Wachovia, the proposed transaction would benefit shareholders of Treasury Series by reducing the amount of the expected increase in operating expenses to be borne by the remaining shareholders of Treasury Series. The Board considered that the exchange of shares pursuant to the transaction will not result in taxable gain or loss for U.S. federal income tax purposes for its shareholders. The Board also considered the fact that the Series have similar policies with respect to purchases, redemptions, exchanges and distributions. The Board of Trustees of Government Securities Trust has also determined that the transaction is in the best interests of shareholders of Money Market Series and that the transaction will not result in a dilution of the pecuniary interests of shareholders of Money Market Series. PI recommended the transaction to the Board of each Series at meetings held on November 18, 2003. In recommending the transaction, PI advised the Board that the Series have similar investment objectives, policies and investment portfolios. DESCRIPTION OF THE SECURITIES TO BE ISSUED Government Securities Trust, which has two series (Treasury Series and Money Market Series), was organized under the laws of Massachusetts on September 22, 1981 as an unincorporated business trust, commonly referred to as a Massachusetts business trust. Government Securities Trust is registered with the United States Securities and Exchange Commission as an open-end management investment company. The Declaration of Trust permits the Trustees to issue an unlimited number of full and fractional shares in separated series and classes within such securities. Treasury Series and Money Market Series are each authorized to issue an unlimited number of shares. The shares of Treasury Series are currently divided into three classes, designated as Class A, Class S and Class Z. The shares of Money Market Series are currently divided into two classes, designated as Class A and Class Z. Each class of common stock represents an interest in the same assets of Money Market Series and is identical in all respects except that: - each class is subject to different expenses which may affect performance; - each class has exclusive voting rights on any matter submitted to shareholders that relates solely to its arrangement and has separate voting rights on any matter submitted to shareholders in which the interests of that class differ from the interests of any other class; - each class has a different exchange privilege; and - Class Z shares are offered exclusively for sale to a limited group of investors. 17 <Page> Shares of Money Market Series, when issued and paid for are fully paid and nonassessable. The voting and dividend rights, the right of redemption and the privilege of exchange are described in Money Market Series' Prospectus. Government Securities Trust does not intend to hold annual meetings of shareholders. There will normally be no meetings of shareholders for the purpose of electing Trustees unless less than a majority of the Trustees holding office have been elected by shareholders, at which time the Trustees then in office will call a shareholder meeting for the election of Trustees. Shareholders of record of two-thirds of the outstanding shares of Government Securities Trust entitled to vote in the election of Trustees may remove a Trustee by votes cast in person or by proxy at a meeting called for that purpose. The Trustees are required to call a meeting of shareholders for the purpose of voting upon the question of removal of any Trustee, or to transact any other business, when requested in writing to do so by the shareholders of record holding at least a majority of shares entitled to vote at the meeting. U.S. FEDERAL INCOME TAX CONSIDERATIONS The transaction is intended to qualify for U.S. federal income tax purposes as a reorganization under the Code. Treasury Series will receive an opinion from Shearman & Sterling LLP, counsel to Treasury Series, substantially to the effect that: 1. The acquisition by Money Market Series of the assets of Treasury Series in exchange solely for voting shares of Money Market Series and the assumption by Money Market Series of the liabilities of Treasury Series, if any, followed by the distribution of the Money Market Series shares acquired by Treasury Series pro rata to its shareholders, will constitute a "reorganization" within the meaning of Section 368(a)(1) of the Code, and Treasury Series and Money Market Series each will be "a party to a reorganization" within the meaning of Section 368(b) of the Code; 2. The shareholders of Treasury Series will not recognize gain or loss upon the exchange of all of their shares of Treasury Series solely for shares of Money Market Series, as described above and in the Agreement; 3. No gain or loss will be recognized by Treasury Series upon the transfer of its assets to Money Market Series in exchange solely for Class A and Class Z shares of Money Market Series and the assumption by Money Market Series of the liabilities of Treasury Series, if any. In addition, no gain or loss will be recognized by Treasury Series on the distribution of such shares to the shareholders of Treasury Series; 4. No gain or loss will be recognized by Money Market Series upon the acquisition of the assets of Treasury Series in exchange solely for shares of Money Market Series and the assumption of the liabilities of Treasury Series, if any; 5. Money Market Series' tax basis for the assets acquired from Treasury Series will be the same as the tax basis of these assets when held by Treasury Series immediately before the transfer, and the holding period of such assets acquired by Money Market Series will include the holding period of these assets when held by Treasury Series; 6. Treasury Series' shareholders' tax basis for the shares of Money Market Series to be received by them pursuant to the reorganization will be the same as their tax basis in Treasury Series shares exchanged therefor; and 7. The holding period of Money Market Series shares to be received by the shareholders of Treasury Series will include the holding period of their Treasury Series shares exchanged provided such Treasury Series shares were held as capital assets on the date of the exchange. 18 <Page> An opinion of counsel does not have the effect of a private letter ruling from the Internal Revenue Service (the "IRS") and is not binding on the IRS or any court. If the transaction is consummated but fails to qualify as a "reorganization" within the meaning of section 368 of the Code, the transaction would be treated as a taxable sale of assets by the Treasury Series to the Money Market Series followed by a taxable liquidation of the Treasury Series, and the shareholders of the Treasury Series would recognize a taxable gain or tax loss equal to the difference between their adjusted tax basis in the shares of the Treasury Series and the fair market value of the shares of the Money Market Series received in exchange therefor. The shareholders of the Treasury Series that receive the shares of the Money Market Series pursuant to the transaction may incur taxable gain attributable to unrealized gains of the Money Market Series in the year that the Money Market Series realizes and distributes such gains. This will be true notwithstanding that the value of the shares of the Money Market Series received by such shareholders pursuant to the transaction reflected the appreciation in value attributable to such unrealized gains at the time of the transaction. To the extent that the Treasury Series has loss carryforwards at the time of the transaction, the shareholders of the Treasury Series may not be able to benefit from such loss carryforwards after the transaction. Shareholders of Treasury Series should consult their tax advisers regarding the tax consequences to them of the transaction in light of their individual circumstances. In addition, because the foregoing discussion relates only to the U.S. federal income tax consequences of the transaction, shareholders also should consult their tax advisers as to state, local and foreign tax consequences to them, if any, of the transaction. CONCLUSION The Plan was approved by the Board of Trustees of Government Securities Trust on behalf Treasury Series and Money Market Series, at meetings held on November 18, 2003. The Board determined that the transaction is in the best interests of shareholders of each Series and that the interests of existing shareholders of Treasury Series and Money Market Series, as the case may be, would not be diluted as a result of the transaction. If the shareholders of Treasury Series do not approve the transaction, or if the transaction is not completed, Treasury Series will continue to engage in business as a registered investment company and the Board of Trustees of Government Securities Trust will consider other proposals for Treasury Series, including proposals for the reorganization or liquidation of the Series.

SHAREHOLDER PROPOSALS Government Securities Trust is not required to hold regular annual meetings and, in order to minimize costs, does not intend to hold meetings of shareholders unless so required by applicable law, regulatory policy or if otherwise deemed advisable by its Board. Therefore, it is not practicable to specify a date by which shareholder proposals must be received in order to be incorporated in an upcoming proxy statement for an annual meeting. If the proposal is approved at the Meeting, there will likely not be any future shareholder meetings of Treasury Series. It is the present intention of the Board of Trustees of Government Securities Trust not to hold annual meetings of shareholders unless required to do so by the 1940 Act. 20 <Page> OTHER BUSINESS Management of Treasury Series knows of no business to be presented at the Meeting other than the proposal described in this Proxy Statement. However, if any other matter requiring a shareholder vote should be properly brought before the meeting, the proxies will vote according to their best judgment in the interest of Treasury Series, taking into account all relevant circumstances.

The conservative shift in market sentiment is not surprising in light of doubts about the resilience of the U.S. economic recovery, the rash of corporate governance scandals at major U.S. companies, and the growing threat of war between the United States and Iraq. Concern about the staying power of the economic recovery encouraged a trend toward lower market interest rates. Declining market interest rates naturally reduced the level of income earned in money funds, including each Series. Nevertheless, the Government Securities Trust management team's interest-rate strategy and its analysis of the supply/demand dynamics of money market securities helped each Series provide competitive yields during our fiscal year. On the following pages, the team discusses its investment choices in light of developments in the money markets that had a significant impact on the performance of each Series. Thank you for your continued confidence in Prudential mutual funds. We look forward to serving your future investment needs. Sincerely, David R. Odenath, Jr., President Prudential Government Securities Trust 2 Prudential Government Securities Trust Money Market Series Annual Report November 30, 2002 INVESTMENT ADVISER'S REPORT MONEY MARKET SERIES During our fiscal year that began December 1, 2001, we strove to have a mix of short-term debt securities that enhanced the Series' income stream and allowed the Series to respond promptly to changing conditions in the money markets. It was important to have an investment strategy that afforded much flexibility as historically low interest rates and growing demand for conservative assets made the search for attractively priced money market securities more challenging. The Series initially held a large exposure to securities whose rates adjusted daily based on the federal funds rate--the rate that banks charge each other for overnight loans. It also held a sizable amount of federal agency securities due in six months to one year. We reasoned that if an economic recovery in 2002 prompted the Federal Reserve (the Fed) to increase short-term interest rates, our daily adjustable-rate securities would reset to higher levels and boost the Series' income stream. However, if deteriorating economic conditions in 2002 led the Fed to continue its campaign to lower short-term rates, the Series would benefit from the fact that we had locked in yields on six- month and one-year securities before rates moved even lower. Economic conditions improved in early 2002, aided by repeated reductions in short-term rates during 2001. There was speculation that the Fed would soon begin to increase short-term rates to prevent the economy from growing too rapidly and boosting inflation. Anticipation of tighter monetary policy led investors to require higher yields (and lower prices) on money market securities. In early February 2002, we locked in higher yields on federal agency issues maturing in six months to one year. Money market yields continued to rise until mid-March 2002. 3 Prudential Government Securities Trust Money Market Series Annual Report November 30, 2002 Concerns about weak corporate profits and doubts about the quality of corporate financial reporting caused some investors who traditionally buy corporate obligations to purchase federal agency securities that are considered to be safer. This growing demand for more conservative assets made federal agency securities relatively expensive compared to lower-quality money market issues in which this Series does not invest. LESS EXPOSURE TO ADjUSTABLE-RATE SECURITIES The trend toward lower market interest rates resumed in the spring of 2002, reflecting a shift in the outlook for monetary policy. The Fed no longer needed to increase short-term rates because economic growth slowed dramatically in the spring due to less vigorous consumer spending and a continued weakness in business investment. This data encouraged belief the Fed could afford to wait until the second half of 2002 to boost short-term rates. In the summer of 2002, the outlook for monetary policy changed again. Concern that the economy might lapse into a so-called "double-dip" recession and a sell-off in stocks aggravated by the deepening corporate governance scandals encouraged belief that the Fed would soon lower short-term rates to stimulate growth. Consequently, money market yields continued to decline during the summer. We reinvested proceeds from our maturing adjustable-rate securities into repurchase agreements, an alternative short-term investment vehicle. We also bought debt issues due in two to three months and federal agency securities scheduled to mature in 13 months that could be retired early (or called) by their issuers in three months. Purchasing callable securities enhanced the Series' income stream as they were priced attractively compared to noncallable federal agency issues. 4 www.prudential.com (800) 225-1852 Anticipation of easier monetary policy drove money market yields even lower in the autumn of 2002. The long-anticipated move finally occurred in early November 2002 as Fed policymakers voted to reduce short-term rates by another half of a percentage point. This lowered the target for the federal funds rate to 1.25%. In explaining their actions, the central bankers noted that geopolitical risks and other factors hurt spending, production, and employment. LOOKING AHEAD The economic outlook still remains uncertain, particularly in light of the possibility of war between the United States and Iraq and a continued reluctance of businesses to make significant new investments. Until economic growth is on a firm foundation, the Fed will be disinclined to increase the target for the federal funds rate. In that case, the current low-interest-rate environment could persist for most of 2003. 5 Prudential Government Securities Trust U.S. Treasury Money Market Series Annual Report November 30, 2002 INVESTMENT ADVISER'S REPORT U.S. TREASURY MONEY MARKET SERIES In shaping our investment strategy for our fiscal year that began December 1, 2001, we considered several key developments. Among these were the liquidity needs of our shareholders that typically shift at certain times of the year, as well as the changing outlook for monetary policy in the United States. In addition, there was a growing preference for U.S. Treasury money market securities as accounting scandals at major firms caused even greater concern about the quality of corporate financial reporting. There was also a considerable rise in the issuance of some U.S. Treasury bills, which are sold by the federal government at a discount to their face value. We began our fiscal year by investing primarily in Treasury securities scheduled to mature throughout January and February 2002. Our laddered maturity approach prepares the Series to meet the greater liquidity needs of its shareholders at the start of each calendar year. The economy had also begun to recover in early 2002, helped by repeated reductions in short- term interest rates during 2001. Improving economic conditions led to speculation that the Federal Reserve (the Fed) would soon begin to take back some of its rate cuts to prevent the economy from expanding too fast and boosting inflation. Consequently, investors required higher yields (and lower prices) on Treasuries in the one-year sector. We took advantage of this development by locking in attractive yields on one-year Treasuries during the first quarter of 2002. Purchasing them helped the Series even more than we expected as their prices rallied later in our reporting period, reflecting a shift in the outlook for monetary policy. SAFE HAVEN SOUGHT IN U.S. TREASURIES Although the economy expanded rapidly in the first three months of 2002, growth slowed dramatically in the second quarter, hurt by less vigorous consumer spending and a continued weakness in business investment. This data 6 www.prudential.com (800) 225-1852 encouraged belief that the Fed could afford to wait until the second half of 2002 to boost short-term rates. With monetary policy now expected to remain on hold in the spring of 2002, investors were willing to accept lower yields on Treasuries due in one year. We invested primarily in Treasuries maturing in six months because at that time we believed their yields compared favorably with yields on one-year Treasuries. In addition to the struggling economic recovery, market participants had to contend in the summer of 2002 with another round of corporate governance scandals that focused primarily on WorldCom, a telecommunications firm. This turn of events further undermined investor confidence in corporate accounting and reporting practices. Not surprisingly, the flight-to-quality trend that was evident earlier in our reporting period continued as many traditional buyers of commercial paper (corporate debt obligations that mature in 270 days or less) sought refuge in Treasuries for their relative safety. FOCUS ON U.S. TREASURY BILLS HELPED THE SERIES We primarily invested in Treasury bills maturing in one, three, or six months as opposed to Treasury notes and bonds due in six months or less. The Department of the Treasury has greatly increased its issuance of bills to help finance the nation's first federal budget deficit in several years. The federal deficit increased due to a combination of tax cuts, the economic downturn in 2001, and increased government spending on security measures following the terrorist attacks on the United States on September 11, 2001. Because of their greater supply, Treasury bills yielded more than Treasury notes and bonds with the same time left to maturity. Indeed, we took profits on some of the Series' Treasury notes and bonds and bought more attractively priced bills. We continued to emphasize Treasury bills throughout the 7 Prudential Government Securities Trust U.S. Treasury Money Market Series Annual Report November 30, 2002 remainder of our reporting period as money market yields declined even further because the Fed was expected to resume cutting short-term rates to support the faltering economic recovery. The widely anticipated move came in early November 2002 when Fed policymakers voted to reduce short-term rates by another half of a percentage point. This lowered the target for the federal funds rate (what banks charge each other to borrow money overnight) to 1.25%. In explaining their actions, the central bankers noted that geopolitical risks and other factors hurt spending, production, and employment. LOOKING AHEAD The economic outlook still remains uncertain, particularly in light of the possibility of war between the United States and Iraq and a continued reluctance of businesses to make significant new investments. Until economic growth is on a firm foundation, the Fed will be disinclined to increase the target for the federal funds rate. In that case, the current low-interest-rate environment could persist for most of 2003. Thank you for investing in Prudential money market funds.

See Notes to Financial Statements 15 <Page> Prudential Government Securities Trust Notes to Financial Statements Prudential Government Securities Trust (the "Fund") is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Fund consists of two series: the Money Market Series and the U.S. Treasury Money Market Series (each a "Series"); the monies of each series are invested in separate, independently managed portfolios. The Money Market Series seeks high current income, preservation of capital and maintenance of liquidity by investing primarily in a diversified portfolio of short-term money market instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities that mature in 13 months or less. The U.S. Treasury Money Market Series seeks high current income consistent with the preservation of principal and liquidity by investing exclusively in U.S. Treasury obligations that mature in 13 months or less. Note 1. Significant Accounting Policies The following is a summary of significant accounting policies followed by the Fund and each Series in the preparation of its financial statements. Securities Valuations: Portfolio securities of the Fund are valued at amortized cost, which approximates market value. The amortized cost method of valuation involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of any discount or premium. Repurchase Agreements: In connection with transactions in repurchase agreements with U.S. financial institutions, it is the Fund's policy that its custodian or designated subcustodians, as the case may be under triparty repurchase agreements, take possession of the underlying collateral securities, the value of which exceeds the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase agreement exceeds one business day, the value of the collateral is marked-to-market on a daily basis to ensure the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. Securities Transactions and Investment Income: Securities transactions are recorded on the trade date. Realized gains (losses) on sales of securities are calculated on the identified cost basis. The Fund amortizes premiums and accretes discounts on purchases of portfolio securities as adjustments to interest income. Interest income is recorded on the accrual basis. Expenses are recorded on the accrual basis which may require the use of certain estimates by management. The Fund's expenses are allocated to the respective Series on the basis of relative net assets except for Series specific expenses which are allocated at a Series or class level. 16 <Page> Prudential Government Securities Trust Notes to Financial Statements Cont'd. Dividends and Distributions: The Fund declares daily dividends from net investment income and net realized short-term capital gains or losses. Payment of dividends is made monthly. Income distributions and realized capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Federal Income Taxes: For federal income tax purposes, each Series of the Fund is treated as a separate taxable entity. It is each Series' policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable net income and capital gains, if any, to shareholders. Therefore, no federal income tax provision is required. Note 2. Agreements The Fund has a management agreement with Prudential Investments LLC ("PI"). Pursuant to this agreement, PI has responsibility for all investment advisory services and supervises the subadviser's performance of such services. PI has entered into a subadvisory agreement with Prudential Investment Management, Inc. ("PIM"). PIM furnishes investment advisory services in connection with the management of the Fund. PI pays for the services of PIM, the compensation of officers of the Fund, occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly based on the average daily net assets of each Series. With respect to the Money Market Series, the management fee is payable as follows: .40 of 1% of average daily net assets up to $1 billion, .375 of 1% of the average daily net assets between $1 billion and $1.5 billion and .35 of 1% in excess of $1.5 billion. With respect to the U.S. Treasury Money Market Series, the management fee is payable at an annual rate of .40 of 1% of the average daily net assets of the Series. The Fund has a distribution agreement with Prudential Investment Management Services LLC ("PIMS"), which acts as the distributor of the Class A and Class Z shares of the Fund. The Fund compensates PIMS for distributing and servicing the Fund's Class A shares, pursuant to a plan of distribution (the "Class A Plan"), regardless of expenses actually incurred by PIM. The distribution fees for Class A shares are accrued daily and payable monthly. The distributor pays various broker-dealers for account servicing fees and for the expenses incurred by such broker-dealers. No distribution or service fees are paid to PIMS as distributor of the Class Z shares of the Fund. Pursuant to the Class A Plan, the Money Market Series and the U.S. Treasury Money Market Series compensate PIMS at an annual rate of .125 of 1% of each Series' Class A average daily net assets. 17 <Page> Prudential Government Securities Trust Notes to Financial Statements Cont'd.

Distributions and Tax Information Distributions to shareholders, which are determined in accordance with federal income tax regulations and which may differ from generally accepted accounting principles, are recorded on the ex-dividend date.

For the year ended November 30, 2002, the adjustments were to decrease net realized gains on investments and increase net investment income by $108,891 and $327,216, respectively for the Money Market Series and US Treasury Money Market Series.

As of November 30, 2002, the Fund had no distributable earnings. Note 5. Capital The Fund offers Class A and Class Z shares.

These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at November 30, 2002 by correspondence with the custodian, provide a reasonable basis for our opinion.

It's quite understandable. These annual and semiannual reports are prepared to comply with federal regulations, and are often written in language that is difficult to understand. So when most people run into those particularly daunting sections of these reports, they don't read them. WE THINK THAT'S A MISTAKE At Prudential, we've made some changes to our mutual funds report to make it easier to understand and more pleasant to read. We hope you'll find it profitable to spend a few minutes familiarizing yourself with your investment. Here's what you'll find in the report: PERFORMANCE AT A GLANCE Since an investment's performance is often a shareholder's primary concern, we present performance information in two different formats. You'll find it first on the "Performance at a Glance" page where we compare the Fund and the comparable average calculated by Lipper, Inc., a nationally recognized mutual fund rating agency. We report both the cumulative total returns and the average annual total returns. The cumulative total return is the total amount of income and appreciation the Fund has achieved in various time periods. The average annual total return is an annualized representation of the Fund's performance. It gives you an idea of how much the Fund has earned in an average year for a given time period. Under the performance box, you'll see legends that explain the performance information, whether fees and sales charges have been included in the returns, and the inception dates for the Fund's share classes. See the performance comparison charts at the back of the report for more performance information. Please keep in mind that past performance is not indicative of future results. www.prudential.com (800) 225-1852 INVESTMENT ADVISER'S REPORT The portfolio manager, who invests your money for you, reports on successful--and not-so-successful--strategies in this section of your report. Look for recent purchases and sales here, as well as information about the sectors the portfolio manager favors, and any changes that are on the drawing board. PORTFOLIO OF INVESTMENTS This is where the report begins to appear technical, but it's really just a listing of each security held at the end of the reporting period, along with valuations and other information. Please note that sometimes we discuss a security in the "Investment Adviser's Report" section that doesn't appear in this listing, because it was sold before the close of the reporting period. STATEMENT OF ASSETS AND LIABILITIES The balance sheet shows the assets (the value of the Fund's holdings), liabilities (how much the Fund owes), and net assets (the Fund's equity or holdings after the Fund pays its debts) as of the end of the reporting period. It also shows how we calculate the net asset value per share for each class of shares. The net asset value is reduced by payment of your dividend, capital gain, or other distribution--but remember that the money or new shares are being paid or issued to you. The net asset value fluctuates daily, along with the value of every security in the portfolio. STATEMENT OF OPERATIONS This is the income statement, which details income (mostly interest and dividends earned) and expenses (including what you pay us to manage your money). You'll also see capital gains here--both realized and unrealized. Prudential Government Securities Trust Getting the Most from Your Prudential Mutual Fund STATEMENT OF CHANGES IN NET ASSETS This schedule shows how income and expenses translate into changes in net assets. The Fund is required to pay out the bulk of its income to shareholders every year, and this statement shows you how we do it (through dividends and distributions) and how that affects the net assets. This statement also shows how money from investors flowed into and out of the Fund. NOTES TO FINANCIAL STATEMENTS This is the kind of technical material that can intimidate readers, but it does contain useful information. The notes provide a brief history and explanation of your Fund's objectives. In addition, they outline how Prudential mutual funds prices securities. The notes also explain who manages and distributes the Fund's shares and, more important, how much they are paid for doing so. Finally, the notes explain how many shares are outstanding and the number issued and redeemed over the period. FINANCIAL HIGHLIGHTS This information contains many elements from prior pages, but on a per-share basis. It is designed to help you understand how the Fund performed, and to compare this year's performance and expenses to those of prior years. INDEPENDENT ACCOUNTANT'S REPORT Once a year, an independent accountant looks over our books and certifies that the financial statements are fairly presented in accordance with generally accepted accounting principles. TAX INFORMATION This is information that we report annually about how much of your total return is taxable. Should you have any questions, you may want to consult a tax adviser. www.prudential.com (800) 225-1852 PERFORMANCE COMPARISON These charts are included in the annual report and are required by the Securities Exchange Commission. Performance is presented here as the return on a hypothetical $10,000 investment in the Fund since its inception or for 10 years (whichever is shorter). To help you put that return in context, we are required to include the performance of an unmanaged, broad-based securities index as well. The index does not reflect the cost of buying the securities it contains or the cost of managing a mutual fund. Of course, the index holdings do not mirror those of the Fund--the index is a broad-based reference point commonly used by investors to measure how well they are doing. A definition of the selected index is also provided. Investors cannot invest directly in an index.

The Fund consists of two series: the Money Market Series and the U.S. Treasury Money Market Series (each a "Series"); the monies of each series are invested in separate, independently managed portfolios. The Money Market Series seeks high current income, preservation of capital and maintenance of liquidity by investing primarily in a diversified portfolio of short-term money market instruments issued or guaranteed by the U.S. Government or its agencies or instrumentalities that mature in 13 months or less. The U.S. Treasury Money Market Series seeks high current income consistent with the preservation of principal and liquidity by investing exclusively in U.S. Treasury obligations that mature in 13 months or less. Note 1. Significant Accounting Policies The following is a summary of significant accounting policies followed by the Fund and each Series in the preparation of its financial statements. Securities Valuations: Portfolio securities are valued at amortized cost, which approximates market value. The amortized cost method of valuation involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of any discount or premium. Repurchase Agreements: In connection with transactions in repurchase agreements with U.S. financial institutions, it is the Fund's policy that its custodian or designated subcustodians, as the case may be under triparty repurchase agreements, take possession of the underlying collateral securities, the value of which exceeds the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase agreement exceeds one business day, the value of the collateral is marked-to-market on a daily basis to ensure the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. Securities Transactions and Investment Income: Securities transactions are recorded on the trade date. Realized gains (losses) on sales of securities are calculated on the identified cost basis. Interest income, including amortization of premium and accretion of discount on debt securities, is recorded on the accrual basis. Expenses are recorded on the accrual basis, which may require the use of certain estimates by management. The Fund's expenses are allocated to the respective Series on the basis of relative net assets except for Series specific expenses which are allocated at a Series or class level. 10 <Page> Dryden Government Securities Trust Notes to Financial Statements (Unaudited) Cont'd. Dividends and Distributions: The Series declare daily dividends from net investment income and net realized short-term capital gains or losses. Payment of dividends is made monthly. Income distributions and realized capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Federal Income Taxes: For federal income tax purposes, each Series of the Fund is treated as a separate taxable entity. It is each Series' policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its taxable net income and capital gains, if any, to its shareholders. Therefore, no federal income tax provision is required. Note 2. Agreements The Fund has a management agreement with Prudential Investments LLC ("PI"). Pursuant to this agreement, PI has responsibility for all investment advisory services and supervises the subadviser's performance of such services. PI has entered into a subadvisory agreement with Prudential Investment Management, Inc. ("PIM"). PIM furnishes investment advisory services in connection with the management of the Fund. PI pays for the services of PIM, the compensation of officers of the Fund, occupancy and certain clerical and bookkeeping costs of the Fund. The Fund bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly based on the average daily net assets of each Series. With respect to the Money Market Series, the management fee is payable as follows: .40 of 1% of average daily net assets up to $1 billion, .375 of 1% of the average daily net assets between $1 billion and $1.5 billion and .35 of 1% in excess of $1.5 billion. With respect to the U.S. Treasury Money Market Series, the management fee is payable at an annual rate of .40 of 1% of the average daily net assets of the Series. The Fund has a distribution agreement with Prudential Investment Management Services LLC ("PIMS"), which acts as the distributor of the Class A and Class Z shares of the Fund. The Fund compensates PIMS for distributing and servicing the Fund's Class A shares, pursuant to a plan of distribution (the "Class A Plan"), regardless of expenses actually incurred by PIM. The distribution fees for Class A shares are accrued daily and payable monthly. The distributor pays various broker-dealers for account servicing fees and for the expenses incurred by such broker-dealers. No distribution or service fees are paid to PIMS as distributor of the Class Z shares of the Fund. 11 <Page> Dryden Government Securities Trust Notes to Financial Statements (Unaudited) Cont'd. Pursuant to the Class A Plan, the Money Market Series and the U.S. Treasury Money Market Series compensate PIMS at an annual rate of 0.125 of 1% of each Series' Class A average daily net assets. PI, PIM and PIMS are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ("Prudential"). Note 3. Other Transactions with Affiliates Prudential Mutual Fund Services LLC ("PMFS"), an affiliate of PI and an indirect, wholly-owned subsidiary of Prudential, serves as the Fund's transfer agent. During the six months ended May 31, 2003, the Fund incurred fees of approximately $420,200 and $111,600, respectively, for the Money Market Series and U.S. Treasury Money Market Series. As of May 31, 2003, approximately $70,900 and $16,800 of such fees were due to PMFS, respectively, for the Money Market Series and U.S. Treasury Money Market Series. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to non-affiliates. Note 4. Joint Repurchase Agreement Account The Money Market Series, along with other affiliated registered investment companies, transfers uninvested cash balances into a single joint account, the daily aggregate balance of which is invested in one or more repurchase agreements collateralized by U.S. Treasury or federal agency obligations. As of May 31, 2003, the Money Market Series had a 11.70% undivided interest in the joint account. The undivided interest for the Fund represents $26,000,000 in principal amount. As of such date, each repurchase agreement in the joint account and the collateral therefore were as follows: Greenwich Capital Markets, Inc., 1.37%, in the principal amount of $74,084,000, repurchase price $74,092,458, due 6/2/03. The value of the collateral including accrued interest was $75,567,236. SBC Warburg Asia Limited, 1.36%, in the principal amount of $74,084,000, repurchase price $74,092,396, due 6/2/03. The value of the collateral including accrued interest was $75,565,882. J.P. Morgan Chase, 1.35%, in the principal amount of $74,084,000, repurchase price $74,092,334, due 6/2/03. The value of the collateral including accrued interest was $75,566,458. Note 5. Capital The Fund offers Class A and Class Z shares. Neither Class A nor Class Z shares are subject to any sales or redemption charge. Class Z shares are offered exclusively for 12 <Page> Dryden Government Securities Trust Notes to Financial Statements (Unaudited) Cont'd. sale to a limited group of investors. Each series has authorized an unlimited number of shares of beneficial interest at $.01 par value.

INDEMNIFICATION. Article V, Section 5.3 of the Registrant's Amended and Restated Declaration of Trust provides that the Trustees shall provide for indemnification by the Trust of every person who is, or has been, a Trustee or officer of the Trust against all liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been a Trustee or officer and against amounts paid or incurred by him in the settlement thereof, in such manner not otherwise prohibited or limited by law as the Trustees may provide from time to time in the By-Laws. Section 5.1 also provides that Trustees, officers, employees or agents of the Trust shall not be subject to any personal liability to any other person, other than the Trust or its shareholders, in connection with Trust property or the affairs of the Trust, except liability arising from bad faith, willful misfeasance, gross negligence or reckless disregard of his or her duties. Section 5.1 also provides that the Registrant will indemnify and hold harmless each shareholder from and against all claims and liabilities to which such shareholder may become subject by reason of his being or having been a shareholder and shall reimburse such shareholder for all expenses reasonably related thereto. As permitted by Sections 17(h) and (i) of the 1940 Act and pursuant to Article VII of the Fund's By-Laws (Exhibit (b) to the Registration Statement), in certain cases, an individual who is a present or former officer, Trustee, employee or agent of the Registrant or who serves or has served another trust, corporation, partnership, joint venture or other enterprise in one of such capacities at the request of the Registrant (a representative of the Trust) may be indemnified by the Registrant against certain liabilities in connection with the Registrant provided that such representative acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Registrant, subject to certain qualifications and exceptions including liabilities to the Registrant or to its shareholders to which such representative would otherwise be subject by reason of wilful misfeasance, bad faith, gross negligence or reckless disregard of duties. As permitted by Section 17(i) of the Investment Company Act and pursuant to Section 10 of the Distribution Agreement (Exhibit 6(e)(1) to the Registration Statement), in certain cases the Distributor of the Registrant may be indemnified against liabilities which it may incur except liabilities arising from bad faith, gross negligence, in the performance of its duties, willful misfeasance or reckless disregard of duties. Such Article V of the Declaration of Trust, Article VII of the By-Laws, as amended and Section 10 of the Distribution Agreement are hereby incorporated by reference in their entirety. The Trust has purchased an insurance policy insuring its officers and Trustees against certain liabilities, and certain costs of defending claims against such officers and Trustees, to the extent such officers and Trustees are not found to have committed conduct constituting willful misfeasance, bad faith, gross negligence or reckless disregard in the performance of their duties. The insurance policy also insures the Trust against the cost of indemnification payments to officers and Trustees under certain circumstances. Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, (Securities Act) may be permitted to Trustees, officers and controlling persons of the Registrant and the principal underwriter pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Investment Company Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a Trustee, officer, or controlling person of the Registrant and the principal underwriter in connection with the successful defense of any action, suit or proceeding) is asserted against the Registrant by such Trustee, officer or controlling person or the principal underwriter in connection with the shares being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Investment Company Act and will be governed by the final adjudication of such issue. Pursuant and subject to the provisions of Article XI of the Registrant's By-Laws, the Registrant shall indemnify each representative of the Trust against, or advance the expenses of a representative of the Trust for, the amount of any deductible provided in any liability insurance policy maintained by the Registrant. Section 9 of the Management Agreement (Exhibit (d)(1) to the Registration Statement) and Section 4 of the Subadvisory Agreement (Exhibit (d)(2) to the Registration Statement) limit the liability of Prudential Investments LLC (PI) and Prudential Investment Management, Inc. (PIM), respectively, to liabilities arising from willful misfeasance, bad faith or gross negligence in the performance of their respective duties or from reckless disregard by them of their respective obligations and duties under the agreements. Section 9 of the Management Agreement also holds PI liable for losses resulting from a breach of fiduciary duty with respect to the receipt of compensation for services. The Registrant hereby undertakes that it will apply the indemnification provisions of its Declaration of Trust, By-Laws and the Distribution Agreement in a manner consistent with Release No. 11330 of the Securities and Exchange Commission under the Investment Company Act so long as the interpretations of Sections 17(h) and 17(i) of such Act remain in effect and are consistently applied.
