Dear Shareholder

    I am writing to ask you to vote on an important proposal whereby the assets
of U.S. Treasury Money Market Series (Treasury Series) would be acquired by
Money Market Series. 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.

      www.proxyvote.com. Enter your 12-digit control number from your proxy

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.

IS THE TRANSACTION A TAXABLE EVENT FOR FEDERAL INCOME TAX PURPOSES?

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

solicitation of proxy votes.

HAS THE BOARD OF TRUSTEES APPROVED THE PROPOSAL?

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.

                       SPECIAL MEETING OF SHAREHOLDERS OF
    DRYDEN GOVERNMENT SECURITIES TRUST -- U.S. TREASURY MONEY MARKET SERIES
                   TO BE HELD ON MARCH 19, 2004 AT 11:00 A.M.

                              100 MULBERRY STREET

                         PROXY STATEMENT AND PROSPECTUS

                            ------------------------

                               VOTING INFORMATION

    This Proxy Statement and Prospectus (Proxy Statement) is furnished in
connection with a solicitation of proxies made by, and on behalf of, the Board
of Trustees of Dryden Government Securities Trust (Government Securities Trust)
on behalf of U.S. Treasury Money Market Series (Treasury Series) to be used at a
Special Meeting (the Meeting) of the shareholders of Treasury Series, to be held
on March 19, 2004, at 11:00 a.m. Eastern Standard Time at 100 Mulberry Street,
Gateway Center Three, 14th Floor, Newark, New Jersey 07102.

    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:

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

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.

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.

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.

                       INVESTMENT OBJECTIVES AND POLICIES

    If the transaction is approved, the shareholders of Treasury Series will
become shareholders of Money Market Series. 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.

NOTICE TO BANKS, BROKER-DEALERS AND VOTING TRUSTEES AND THEIR NOMINEES

    Please advise Treasury Series, care of Prudential Investment Management

                             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.

any other matter requiring a shareholder vote should be properly brought before

                                                                    ATTACHMENT A

                         FORM OF PLAN OF REORGANIZATION

    THIS PLAN OF REORGANIZATION (the "Plan") is made as of this   th day of
        , 2004, by Dryden Government Securities Trust (the "Trust"), a business
trust organized under the laws of the Commonwealth of Massachusetts with its
principal place of business at Gateway Center Three, 100 Mulberry Street,
Newark, New Jersey 07102, on behalf of the Money Market Series (the "Acquiring
Fund") and the U.S. Treasury Money Market Series (the "Acquired Fund"), both
series of the Trust. Together, the Acquiring Fund and Acquired Fund are referred
to as the "Funds."

    The reorganization (hereinafter referred to as the "Reorganization") will
consist of (i) the acquisition by the Acquiring Fund, of substantially all of
the property, assets and goodwill of the Acquired Fund and the assumption by the
Acquiring Fund of all of the liabilities of the Acquired Fund in exchange solely
for full and fractional shares of beneficial interest, par value $0.001 each, of
the Acquiring Fund ("Acquiring Fund Shares"); (ii) the distribution of Acquiring
Fund Shares to the shareholders of the Acquired Fund according to their
respective interests in complete liquidation of the Acquired Fund; and
(iii) the dissolution of the Acquired Fund as soon as practicable after the
closing (as defined in Section 3, hereinafter called the "Closing"), all upon
and subject to the terms and conditions of this Plan hereinafter set forth.

    In order to consummate the Plan, the following actions shall be taken by the
Trust on behalf of the Acquiring Fund and the Acquired Fund:

    1.  SALE AND TRANSFER OF ASSETS, LIQUIDATION AND DISSOLUTION OF ACQUIRED
FUND.

    (a)  Subject to the terms and conditions of this Plan, the Trust on behalf
of the Acquired Fund shall convey, transfer and deliver to the Acquiring Fund at
the Closing all of the Acquired Fund's then existing assets, free and clear of
all liens, encumbrances, and claims whatsoever (other than shareholders' rights
of redemption), except for cash, bank deposits, or cash equivalent securities in
an estimated amount necessary to (i) pay the costs and expenses in carrying out
this Plan (including, but not limited to, fees of counsel and accountants, and
expenses of its liquidation and dissolution contemplated hereunder).
(ii) discharge its unpaid liabilities on its books at the closing date (as
defined in section 3, hereinafter the "Closing Date"), including, but not
limited to, its income dividends and capital gains distributions, if any,
payable for the period prior to, and through, the Closing Date; and (iii) pay
such contingent liabilities as the Board of Trustees shall reasonably deem to
exist against the Acquired Fund, if any, at the Closing Date, for which
contingent and other appropriate liabilities reserves shall be established on
theAcquired Fund's books (hereinafter "Net Assets"). TheAcquired Fund shall also
retain any and all rights that it may have over and against any person that may
have accrued up to and including the close of business on the Closing Date.

    (b)  Subject to the terms and conditions of this Plan, the Trust on behalf
of the Acquiring Fund shall at the Closing deliver to the Acquired Fund the
number of Acquiring Fund Shares, determined by dividing the net asset value per
share of the shares of the Acquired Fund ("Acquired Fund Shares") on the Closing
Date by the net asset value per share of the Acquiring Fund Shares, and
multiplying the result thereof by the number of outstanding Acquired Fund Shares
as of the close of regular trading on the New York Stock Exchange (the "NYSE")
on the Closing Date. All such values shall be determined in the manner and as of
the time set forth in Section 2 hereof.

    (c)  Immediately following the Closing, the Acquired Fund shall distribute
pro rata to its shareholders of record as of the close of business on the
Closing Date, the Acquiring Fund Shares received by the Acquired Fund pursuant
to this Section 1 and then shall terminate and dissolve. Such liquidation and
distribution shall be accomplished by the establishment of accounts on the share
records of the Trust relating to the Acquiring Fund and noting in such accounts
the type and amounts of Acquiring Fund

                                      A-1
<Page>
Shares that former Acquired Fund shareholders are due based on their respective
holdings of the Acquired Fund as of the close of business on the Closing Date.
Fractional Acquiring Fund Shares shall be carried to the third decimal place.
The Acquiring Fund shall not issue certificates representing the Acquiring Fund
shares in connection with such exchange.

    2.  VALUATION.

    (a)  The value of the Acquired Fund's Net Assets to be transferred to the
Acquiring Fund hereunder shall be computed as of the close of regular trading on
the NYSE on the Closing Date (the "Valuation Time") using the valuation
procedures set forth in Trust's currently effective prospectus.

concerning the Funds shall be true and correct as of the Closing with the same
effect as though made as of and at such date; (ii) performance of all
obligations required by this Plan to be performed by the Trust on behalf of the
Funds shall occur prior to the Closing; and (iii) the Trust shall execute a
certificate signed by the President or a Vice President and by the Secretary or
equivalent officer to the foregoing effect.

    (b)  That the form of this Plan shall have been adopted and approved by the
appropriate action of the Board of Trustees of the Trust on behalf of the Funds.

    (c)  That the U.S. Securities and Exchange Commission shall not have issued
an unfavorable management report under Section 25(b) of the 1940 Act or
instituted or threatened to institute any proceeding seeking to enjoin
consummation of the Plan under Section 25(c) of the 1940 Act. And, further, no
other legal, administrative or other proceeding shall have been instituted or
threatened that would materially affect the financial condition of a Fund or
would prohibit the transactions contemplated hereby.

    (d)  That the Plan contemplated hereby shall have been adopted and approved
by the appropriate action of the shareholders of the Acquired Fund at an annual
or special meeting or any adjournment thereof.

    (e)  That a distribution or distributions shall have been declared for each
Fund, prior to the Closing Date that, together with all previous distributions,
shall have the effect of distributing to shareholders of each Fund (i) all of
its ordinary income and all of its capital gain net income, if any, for the
period from the close of its last fiscal year to the Valuation Time and
(ii) any undistributed ordinary income and capital gain net income from any
prior period. Capital gain net income has the meaning assigned to such term by
Section 1222(9) of the Code.

    (f)  That there shall be delivered to the Trust on behalf of the Funds an
opinion in form and substance satisfactory to it from Shearman & Sterling LLP,
counsel to the Trust, to the effect that, subject

<Page>
in all respects to the effects of bankruptcy, insolvency, reorganization,
moratorium, fraudulent conveyance, and other laws now or hereafter affecting
generally the enforcement of creditors' rights:

          (1)  Acquiring Fund Shares to be issued pursuant to the terms of this
    Plan have been duly authorized and, when issued and delivered as provided in
    this Plan, will have been validly issued and fully paid and will be
    non-assessable by the Trust, on behalf of the Acquiring Fund;

          (2)  All actions required to be taken by the Trust and/or Funds to
    authorize and effect the Plan contemplated hereby have been duly authorized
    by all necessary action on the part of the Trust and the Funds;

          (3)  Neither the execution, delivery nor performance of this Plan by
    the Trust violates any provision of the Trust's Amended and Restated Charter
    or By-laws, or the provisions of any agreement or other instrument known to
    such counsel to which the Trust is a party or by which the Funds are
    otherwise bound; this Plan is the legal, valid and binding obligation of the
    Trust and each Fund and is enforceable against the Trust and/or each Fund in
    accordance with its terms; and

          (4)  The Trust's registration statement, of which the prospectus dated
    January 31, 2003 relating to each Fund (the "Prospectus") is a part, is, at
    the time of the signing of this Plan, effective under the 1933 Act, and, to
    the best knowledge of such counsel, no stop order suspending the
    effectiveness of such registration statement has been issued, and no
    proceedings for such purpose have been instituted or are pending before or
    threatened by the U.S. Securities and Exchange Commission under the 1933
    Act, and nothing has come to counsel's attention that causes it to believe
    that, at the time the Prospectus became effective, or at the time of the
    signing of this Plan, or at the Closing, such Prospectus (except for the
    financial statements and other financial and statistical data included
    therein, as to which counsel need not express an opinion), contained any
    untrue statement of a material fact or omitted to state a material fact
    required to be stated therein or necessary to make the statements therein
    not misleading; and such counsel knows of no legal or government proceedings
    required to be described in the Prospectus, or of any contract or document
    of a character required to be described in the Prospectus that is not
    described as required.

    In giving the opinions set forth above, counsel may state that it is relying
on certificates of the officers of the Trust with regard to matters of fact, and
certain certifications and written statements of governmental officials with
respect to the good standing of the Trust.

    (g)  That the Trust's Registration Statement with respect to the Acquiring
Fund Shares to be delivered to the Acquired Fund's shareholders in accordance
with this Plan shall have become effective, and no stop order suspending the
effectiveness of the Registration Statement or any amendment or supplement
thereto, shall have been issued prior to the Closing Date or shall be in effect
at Closing, and no proceedings for the issuance of such an order shall be
pending or threatened on that date.

    (h)  That the Acquiring Fund Shares to be delivered hereunder shall be
eligible for sale by the Acquiring Fund with each state commission or agency
with which such eligibility is required in order to permit the Acquiring Fund
Shares lawfully to be delivered to each shareholder of the Acquired Fund.

    (i)  That, at the Closing, there shall be transferred to the Acquiring Fund

    (a)  Anything contained in this Plan to the contrary notwithstanding, this
Plan may be terminated and abandoned at any time (whether before or after
approval thereof by the shareholders of an Acquired Fund) prior to the Closing
or the Closing may be postponed by the Trust on behalf of a Fund by resolution
of the Board of Trustees, if circumstances develop that, in the opinion of the
Board, make proceeding with the Plan inadvisable.

    (b)  If the transactions contemplated by this Plan have not been consummated
by August 31, 2004, the Plan shall automatically terminate on that date, unless
a later date is agreed to by the Trust on behalf of the relevant Funds.

    (c)  In the event of termination of this Plan pursuant to the provisions
hereof, the same shall become void and have no further effect with respect to
the Acquiring Fund or Acquired Fund, and neither the Trust, the Acquiring Fund
nor the Acquired Fund, nor the directors, officers, agents or shareholders shall
have any liability in respect of this Plan.

    (d)  At any time prior to the Closing, any of the terms or conditions of
this Plan may be waived by the party who is entitled to the benefit thereof by
action taken by the Trust's Board of Trustees if, in the judgment of such Board
of Trustees, such action or waiver will not have a material adverse affect on
the benefits intended under this Plan to its shareholders, on behalf of whom
such action is taken.

    (e)  The respective representations and warranties contained in Sections 4
to 6 hereof shall expire with and be terminated by the Plan of Reorganization,
and neither the Trust nor any of its officers, directors, agents or shareholders
nor the Funds nor any of their shareholders shall have any liability with
respect to such representations or warranties after the Closing. This provision
shall not protect any officer, director, agent or shareholder of any of the
Funds or the Trust against any liability to the entity for which that officer,
director, agent or shareholder so acts or to any of the Trust's shareholders to
which that officer, director, agent or shareholder would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence, or reckless
disregard of the duties in the conduct of such office.

    (f)  If any order or orders of the U.S. Securities and Exchange Commission
with respect to this Plan shall be issued prior to the Closing and shall impose
any terms or conditions that are determined by action of the Board of Trustees
of the Trust on behalf of the Funds to be acceptable, such terms and conditions
shall be binding as if a part of this Plan without further vote or approval of
the shareholders of the Acquired Fund, unless such terms and conditions shall
result in a change in the method of computing the number of Acquiring Fund
Shares to be issued to the Acquired Fund in which event, unless such terms and
conditions shall have been included in the proxy solicitation material furnished
to the shareholders of the Acquired Fund prior to the meeting at which the
transactions contemplated by this Plan shall have been approved, this Plan shall
not be consummated and shall terminate unless the Trust on behalf of the
Acquired Fund shall promptly call a special meeting of shareholders at which
such conditions so imposed shall be submitted for approval.

DEAR SHAREHOLDER,
The fiscal year of the Money Market Series and
the U.S. Treasury Money Market Series ended
November 30, 2002.  This was a time of
dwindling confidence in riskier financial
assets and growing interest in investment
alternatives that provide relative safety of
principal and liquidity. 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

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.

             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.

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

           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

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.

     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.

      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

             Notes to Financial Statements Cont'd.

      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 year ended November 30, 2002, the Fund incurred fees of
approximately $956,200 and $177,400, respectively, for the Money Market Series
and U.S. Treasury Money Market Series. As of November 30, 2002, approximately
$75,900 and $11,000 of such fees were due to PMFS, respectively, for the Money
Market Series and U.S. Treasury Money Market Series.

Note 4. 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. In order to present
undistributed net investment income, accumulated net realized capital gains
(losses) and paid-in capital on the Statement of Assets and Liabilities that
more closely represent their tax character, certain adjustments have been made
to undistributed net investment income and accumulated net realized gains on
investments. 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.

      For the year ended November 30, 2002, the tax character of the dividends
paid, as reflected in the Statement of Changes in Net Assets, of $7,462,253 and
$6,540,728 for the Money Market Series and U.S. Treasury Money Market Series
respectively, was ordinary income. As of November 30, 2002, the Fund had no
distributable earnings.

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 sale to a limited group of investors. Each Series has authorized
an unlimited number of shares of beneficial interest at $.01 par value.

      Transactions in shares of beneficial interest and dollars for the Money
Market Series were as follows:

     Prudential Government Securities Trust
             Report of Independent Accountants

To the Shareholders and Trustees of
Prudential Government Securities Trust:

In our opinion, the accompanying statements of assets and liabilities, including
the portfolios of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Money Market Series and U.S.
Treasury Money Market Series (constituting Prudential Government Securities
Trust, hereafter referred to as the "Fund") at November 30, 2002, the results of
each of their operations for the year then ended, the changes in each of their
net assets for each of the two years in the period then ended and the financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States of America.
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.

     Prudential Government Securities Trust
             Federal Income Tax Information (Unaudited)

      We are required by New York, California, Massachusetts, Missouri and
Oregon to inform you that dividends which have been derived from interest on
federal obligations are not taxable to shareholders providing the mutual fund
meets certain requirements mandated by the respective states' taxing
authorities. We are pleased to report that 34.60% of the dividends paid by the
Money Market Series* and 100% of the dividends paid by the U.S. Treasury Money
Market Series qualify for such deduction.

      Shortly after the close of the calendar year ended December 31, 2002, you
will be advised as to the federal tax status of the dividends you received in
calendar year 2002.

      For more detailed information regarding your state and local taxes, you
should contact your tax adviser or the state/local taxing authorities.
* Due to certain minimum portfolio holding requirements in California,
Connecticut and New York, residents of those states will not be able to exclude
interest on federal obligations from state and local tax.

Getting the Most from Your Prudential Mutual Fund

Some mutual fund shareholders won't ever read
this--they don't read annual and semiannual
reports. 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.

DEAR SHAREHOLDER,
Stock markets in the United States and abroad posted
their best quarterly gains in 4 1/2 years in June 2003
and the U.S. bond market rally continued. This has
encouraged a sense of cautious optimism among

regardless of the direction of financial markets, it
is important to remember that a wise investor plans
today for tomorrow's needs.

Whether you are investing for your retirement, your
children's education, or some other goal,
JennisonDryden mutual funds offer the experience,
resources, and professional discipline of three
leading asset management firms that can make a
difference for you. JennisonDryden equity funds are
managed by Jennison Associates and Quantitative
Management. Prudential Fixed Income manages the

A diversified asset allocation strategy is a
disciplined approach to investing that may help you
make more consistent progress toward your goals.
We recommend that you develop a personal asset
allocation strategy  in consultation with a financial
professional who knows you, who understands your
reasons for investing, the time you have to reach
your goals, and the amount of risk you are
comfortable assuming. JennisonDryden mutual funds
offer a wide range of investment choices, and your
financial professional can help you choose the
appropriate funds to implement your strategy.

I was named president of the Dryden Government
Securities Trust in March 2003. Thank you for your

       Dryden Government Securities Trust
             Notes to Financial Statements (Unaudited)

      Dryden Government Securities Trust (the "Fund"), formerly known as
Prudential Government Securities Trust, 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 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.

      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

       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

                               OTHER INFORMATION

ITEM 15. 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.
