JennisonDryden is a service mark of The Prudential Insurance Company of America. JennisonDrydenMutualFunds Dear Shareholder, October 10, 2003 There have been welcome signs that the U.S. economy is growing again. Many corporate executives and investment research analysts are expecting profits to rise as well.

The economic picture continues to change, providing new opportunities and challenges. Regardless of the direction of financial markets, it is important to remember that a wise investor plans today for tomorrow's needs.

The cumulative total returns do not take into account applicable sales charges. If reflected, the applicable sales charges would reduce the cumulative total returns performance quoted. The average annual total returns do take into account applicable sales charges. Without the contractual distribution and service (12b-1) fee waiver of 0.05% and 0.25% for Class A and Class C shares respectively, the returns for these classes would have been lower. The Distributor's 12b-1 fee waiver of 0.25% for Class C shares continued through August 31, 2003. The Series charges a maximum front-end sales charge of 3% for Class A shares and a 12b-1 fee of up to 0.30% annually. Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually. Class Z shares are not subject to a sales charge or 12b-1 fee.

It gives a broad look at how long-term investment- grade municipal bonds have performed. 4The Lipper Florida (FL) Muni Debt Funds Average (Lipper Average) represents returns based on an average return of all funds in the Lipper FL Muni Debt Funds category for the periods noted. Funds in the Lipper Average limit their assets to those securities that are exempt from taxation in Florida. Investors cannot invest directly in an index. 5Taxable equivalent yields reflect federal and applicable state tax rates. The returns for the Lehman Brothers Muni Bond Index would be lower if they included the effects of sales charges, operating expenses of a mutual fund, or taxes.

Dryden Municipal Series Fund/Florida Series 3 Investment Adviser's Report Market Overview and Performance Summary The municipal bond market repeatedly rallied, then sold off, which resulted in a 3.14% return for the fiscal year ended August 31, 2003, based on the Lehman Brothers Municipal Bond Index (the Index). The market's volatility largely reflected uncertainty about the prospects for economic growth in the United States. The outlook was cloudy because investors did not know how much the Federal Reserve (the Fed) would cut short-term interest rates in an effort to stimulate the sluggish economy. There was also concern that U.S. involvement in a war in Iraq might harm the U.S. economy. Our investment strategy aimed to provide the Series with the flexibility to readily respond to changing conditions in the municipal bond market. However, for the 12 months ended August 31, 2003, the Series' Class A shares trailed their benchmark, the Index. This occurred because the Series held bonds that declined in value due to credit quality problems discussed later in the report. The Index also does not reflect the operating expenses of mutual funds. Compared to its peer group, which does take into account operating expenses, the Series' Class A shares performed roughly in line with the Lipper Florida Municipal Debt Funds Average for the 12 months ended August 31, 2003. Early in our reporting period, municipal bonds gained in value to such an extent that we believed a correction in the market was virtually inevitable. When the equity market began to recover in October 2002, demand for municipal bonds faded temporarily and their prices plunged. The tax-exempt market was also pressured by a large amount of newly issued bonds at that time. The sell-off in municipal bonds soon turned into a rally. Investors paid higher prices (and accepted lower yields) for tax-exempt bonds because the Fed was expected to cut short-term rates with the goal of boosting economic growth. In November 2002, it reduced its target for the federal funds rate by half a percentage point to 1.25%. Concern about the economy occurred before and continued after the war in Iraq began in March 2003. Consequently, there was speculation in the financial markets that the Fed would aggressively reduce rates again or buy U.S. Treasury securities, which would also exert downward pressure on the general level of interest rates. This factor helped the municipal bond rally remain on track for the most part until mid-June 2003. At that time, however, the municipal bond market began to sell off along with Treasurys. Economic data suggested that the Fed might not cut rates sharply when it met in late June. Indeed, it only lowered its target for the federal funds rate by a quarter of a percentage point to 1%. For the rest of the reporting period, municipal 4 Visit our website at www.jennisondryden.com bond prices slid in July and stabilized in August. Municipal bond prices were hurt by signs of stronger economic growth, even though the job market remained weak. Credit Quality and Interest-Rate Sensitivity Florida's revenues have been flat in this economic climate, but Florida benefited from not relying upon a personal income tax. Its primary source of revenue is the sales tax, which has suffered minimally. While fiscal pressures exist, we expect Florida to continue to demonstrate sound financial practices. Given the fiscal challenges facing Florida and the frequent changes in the level of interest rates, we continued to work toward achieving the right balance in the Series with regard to two important overlapping characteristics. The first was credit quality, which involves the Series' exposure to high-quality bonds versus low-quality bonds. The second was interest-rate sensitivity, which involves the Series' exposure to bonds with good potential for price appreciation versus bonds that behave defensively during a sell-off in the fixed income market. From the perspective of credit quality, bonds rated Aaa (both insured and uninsured) accounted for roughly 63% of the Series' net assets as of August 31, 2003. We emphasized Aaa-rated bonds because they tend to perform better than lower-quality bonds under challenging economic conditions. However, as accelerating economic growth increases demand for riskier assets, lower-quality bonds tend to outperform Aaa-rated municipal bonds. The Series had some exposure to bonds of below- investment-grade quality. Some lower-quality bonds performed poorly during the reporting period. The Series held Tallahassee Health Facilities bonds for the Tallahassee Memorial Hospital that declined in value and detracted from the Series' returns. Moody's Investors Service (Moody's) downgraded these bonds from Baa1 to Baa2 with a negative outlook. Moody's cited such factors as negative utilization trends, competitive pressures, and increases in malpractice insurance and pension costs. In the volatile interest-rate climate, we maintained a barbell strategy that essentially focused on two types of bonds. One side of our barbell primarily emphasized Aaa-rated, insured zero coupon bonds, which are so named because they pay no interest and are sold at discount prices to make up for their lack of periodic interest payments. Zero coupon bonds are the most interest-rate-sensitive of all bonds, which enables them to perform better than other types of debt securities when interest rates decline and bond prices move higher. The other side of our barbell emphasized intermediate- term bonds whose higher coupon rates provided the Series with considerable interest income. These bonds are considered to have defensive characteristics, as their prices Dryden Municipal Series Fund/Florida Series 5 tend to hold up relatively well when the municipal bond market sells off. The bonds are also attractive to investors because they provide solid income. Periodically readjusting our coupon barbell strategy was one way to change the Series' duration, which measures its sensitivity to fluctuations in the level of interest rates. In general, when we determined that there was a trend toward higher interest rates, we aimed to shorten the Series' duration to help protect its value as rising interest rates pushed municipal bond prices lower. On the other hand, we aimed to lengthen the Series' duration to help it benefit more fully when falling interest rates drove municipal bond prices higher. In general, we employed this tactic periodically once we determined that the decline in interest rates was indeed a trend rather than a temporary development.

Dryden Municipal Series Fund - Florida Series 17 <Page> Notes to Financial Statements Dryden Municipal Series Fund (the 'Fund'), formerly known as Prudential Municipal Series Fund, is registered under the Investment Company Act of 1940, as an open-end management investment company. The Fund was organized as a Massachusetts business trust on May 18, 1984 and consists of six series. These financial statements relate only to Florida Series (the 'Series'). The financial statements of the other series are not present herein. The assets of each are invested in separate, independently managed portfolios. The Series commenced investment operations on December 28, 1990. The Series is non-diversified and seeks to achieve its investment objective of providing the maximum amount of income that is exempt from federal income taxes with the minimum of risk, and investing in securities which will enable its shares to be exempt from the Florida intangibles tax by investing in primarily 'investment grade' tax-exempt securities whose ratings are within the four highest ratings categories by a nationally recognized statistical rating organization or, if not rated, are of comparable quality. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic developments in a specific state, industry or region. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Series, in the preparation of its financial statements. Securities Valuations: The Series values municipal securities (including commitments to purchase such securities on a 'when-issued' basis) on the basis of prices provided by a pricing service which uses information with respect to transactions in comparable securities and various relationships between securities in determining values. If market quotations are not readily available from such pricing service, a security is valued at its fair value as determined under procedures established by the Trustees. Securities, including options, futures contracts and options thereon, for which the primary market is on a national securities exchange, commodities exchange or board of trade are valued at the last sale price on such exchange or board of trade, on the date of valuation or, if there was no sale on such day, at the average of readily available closing bid and asked prices on such day or at the bid price in the absence of an asked price. Securities, including options, that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed to be 18 Visit our website at www.jennisondryden.com <Page> over-the-counter, are valued at the average of the most recently quoted bid and asked prices provided by a principal market maker or dealer. Short-term securities which mature in sixty days or less are valued at amortized cost, which approximates market value. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of the difference between the principal amount due at maturity and cost. Short-term securities which mature in more than sixty days are valued at current market quotations. Financial Futures Contracts: A financial futures contract is an agreement to purchase (long) or sell (short) an agreed amount of securities at a set price for delivery on a future date. Upon entering into a financial futures contract, the Series is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This amount is known as the 'initial margin.' Subsequent payments, known as 'variation margin,' are made or received by the Series each day, depending on the daily fluctuations in the value of the underlying security. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain or loss. When the contract expires or is closed, the gain or loss is realized and is presented in the Statement of Operations as net realized gain (loss) on financial futures transactions. The Series invests in financial futures contracts in order to hedge its existing portfolio securities, or securities the Series intends to purchase, against fluctuations in value caused by changes in prevailing interest rates or market conditions. Should interest rates move unexpectedly, the Series may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets. Interest Rate Swaps: The Series may enter into interest rate swaps. In a simple interest rate swap, one investor pays a floating rate of interest on a notional principal amount and receives a fixed rate of interest on the same notional principal amount for a specified period of time. Alternatively, an investor may pay a fixed rate and receive a floating rate. Interest rate swaps were conceived as asset/liability management tools. In more complex swaps, the notional principal amount may decline (or amortize) over time. During the term of the swap, changes in the value of the swap are recognized as unrealized gains or losses by 'marking-to-market' to reflect the market value of the swap. When the swap is terminated, the Series will record a realized gain(loss) equal to the difference between the proceeds from (or cost of) the closing transaction and the Series' basis in the contract, if any. Dryden Municipal Series Fund - Florida Series 19 <Page> The Series is exposed to credit loss in the event of non-performance by the other party to the interest rate swap. However, the Series does not anticipate non-performance by any counterparty. Inverse Floaters: The Series invests in variable rate securities commonly called 'inverse floaters'. The interest rates on these securities have an inverse relationship to the interest rate of other securities or the value of an index. Changes in interest rates on the other security or index inversely affect the rate paid on the inverse floater, and the inverse floater's price will be more volatile than that of a fixed-rate bond. Additionally, some of these securities contain a 'leverage factor' whereby the interest rate moves inversely by a 'factor' to the benchmark rate. Certain interest rate movements and other market factors can substantially affect the liquidity of inverse floating rate notes. Options: The Series may either purchase or write options in order to hedge against adverse market movements or fluctuations in value caused by changes in prevailing interest rates with respect to securities which the Series currently owns or intends to purchase. The Series' principal reason for writing options is to realize, through receipt of premiums, a greater current return than would be realized on the underlying security alone. When the Series purchases an option, it pays a premium and an amount equal to that premium is recorded as an asset. When the Series writes an option, it receives a premium and an amount equal to that premium is recorded as a liability. The asset or liability is adjusted daily to reflect the current market value of the option. If an option expires unexercised, the Series realizes a gain or loss to the extent of the premium received or paid. If an option is exercised, the premium received or paid is recorded as an adjustment to the proceeds from the sale or the cost of the purchase in determining whether the Series has realized a gain or loss. The difference between the premium and the amount received or paid on effecting a closing purchase or sale transaction is also treated as a realized gain or loss. Gain or loss on purchased options is included in net realized gain (loss) on investment transactions. Gain or loss on written options is presented separately as net realized gain (loss) on written option transactions. The Series, as writer of an option, may have no control over whether the underlying securities may be sold (called) or purchased (put). As a result, the Series bears the market risk of an unfavorable change in the price of the security underlying the written option. The Series, as purchaser of an option, bears the risk of the potential inability of the counterparties to meet the terms of their contracts. Written options, future contracts and swap contracts involve elements of both market and credit risk in excess of the amounts reflected in the Statement of Assets and Liabilities. 20 Visit our website at www.jennisondryden.com <Page> Securities Transactions and Net 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, as required, is recorded on the accrual basis. Expenses are recorded on the accrual basis which may require, the use of certain estimates by management. Net investment income or loss (other than distribution fees, which are charged directly to the respective class) and unrealized and realized gains (losses) are allocated daily to each class of shares based upon the relative proportion of net assets of each class at the beginning of the day. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate taxpaying entity. It is the Series' policy 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. Dividends and Distributions: The Series declares daily dividends from net investment income. Payment of dividends is made monthly. Distributions of net capital gains, if any, are made annually. Dividends and 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 exdividend date. Permanent book/tax differences relating to income and gains are reclassified to paid in capital when they arise. Custody Fee Credits: The Fund has an arrangement with its custodian bank, whereby uninvested cash earns credits which reduce the fees charged by the custodian. The Series could have invested a portion of the cash utilized in connection with the expense offset arrangements in an income producing asset if it had not entered into such arrangement. 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 subadvisor's performance of such services. PI has entered into a subadvisory agreement with Prudential Investment Management, Inc. ('PIM'). The subadvisory agreement provides that PIM furnishes investment advisory services in connection with the management of the Series. In connection therewith, PIM is obligated to keep certain books and records of the Series. PI pays for the services of Dryden Municipal Series Fund - Florida Series 21 <Page> PIM, the compensation of officers of the Series, occupancy and certain clerical and bookkeeping costs of the Series. The Series bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly, at an annual rate of .50 of 1% of the average daily net assets of the Series. The Series has a distribution agreement with Prudential Investment Management Services LLC ('PIMS'), which acts as the distributor of the Series. The Series compensates PIMS for distributing and servicing the Series' Class A, Class B and Class C shares, pursuant to plans of distribution (the 'Class A, B and C Plans') regardless of expenses actually incurred by it. The distribution fees are accrued daily and payable monthly. No distribution or service fees were paid to PIMS as distributor of the Class Z shares of the Series. Pursuant to the Class A, B and C Plans, the Series compensates PIMS for distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1% and up to 1% of the average daily net assets of the Class A, B and C shares, respectively. PIMS has contractually agreed to limit such fees to .25 of 1%, and ..75 of 1% of the average daily net assets of the Class A and Class C shares, respectively. PIMS has advised the Series that they have received approximately $22,800 and $5,100 in front-end sales charges resulting from sales of Class A and C shares, respectively during the year ended August 31, 2003. From these fees, PIMS paid such sales charges to affiliated broker-dealers, which in turn paid commissions to salespersons and incurred other distribution costs. PIMS has advised the Series that for the year ended August 31, 2003, they received approximately $29,500 and $4,100 in contingent deferred sales charges imposed upon certain redemptions by Class B and Class C shareholders, respectively. PI, PIM and PIMS are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). The Series, along with other affiliated registered investment companies (the 'Funds'), is a party to a syndicated credit agreement ('SCA') with a group of banks. For the year ended August 31, 2003, the SCA provides for a commitment of $800 million and allows the Funds to increase the commitment to $1 billion, if necessary. Interest on any borrowings under the SCA will be incurred at market rates. The Funds pay a commitment fee of .08 of 1% of the unused portion of the SCA. The commitment fee is accrued and paid quarterly and is allocated to the Funds pro rata, based on net assets. The purpose of the SCA is to serve as an alternative source of funding to facilitate capital share redemptions. The expiration date of the SCA was May 2, 2003. On May 2, 2003, the SCA was renewed under 22 Visit our website at www.jennisondryden.com <Page> the same terms and conditions ('May 2003 renewal'). The expiration date of the May 2003 renewal is April 30, 2004. The Series did not borrow any amounts pursuant to the SCA during the year ended August 31, 2003. 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 August 31, 2003, the Series incurred fees of approximately $20,300 for the services of PMFS. As of August 31, 2003, approximately $1,600 of such fees were due to PMFS. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to nonaffiliates, where applicable. The Series pays networking fees to affiliated and unaffiliated broker/dealers. These networking fees are payments made to broker/dealers that clear mutual fund transactions through a national clearing system. The Series incurred approximately $4,000 in total networking fees, of which the amount relating to the services of Wachovia Securities LLC ('Wachovia') and Prudential Securities Inc. ('PSI'), affiliates of PI, were approximately $3,600 for the year ended August 31, 2003. Prior to July 1, 2003, PSI was an indirect, wholly-owned subsidiary of Prudential. As of August 31, 2003, approximately $300 of such fees were due to Wachovia. These amounts are included in transfer agent's fees and expenses in the Statement of Operations. NOTE 4. PORTFOLIO SECURITIES Purchases and sales of portfolio securities of the Series, excluding short-term investments, for the year ended August 31, 2003 were $50,814,585 and $59,295,877 respectively. During the year ended August 31, 2003, the Series entered into financial futures contracts.

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 (loss) and accumulated net realized gains (losses) on the Statement of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to paid-in-capital in excess of par, undistributed net investment income (loss) and accumulated net realized gain (loss) on investments. For the year ended August 31, 2003, the adjustments were to increase undistributed net investment income by $35,401, decrease accumulated net realized gain by $29,140 and decrease paid-in capital by $6,261 primarily due to the difference in the treatment of accreting market discount between financial and tax reporting. Net investment income, net realized losses and net assets were not affected by this change. Tax character of distributions paid during the year ended August 31, 2003 were: <Table> <Caption> TAX-EXEMPT LONG-TERM TOTAL INCOME ORDINARY INCOME CAPITAL GAINS DISTRIBUTIONS - ------------------ ------------------ ------------------ ------------------ $3,469,606 $17,204 $132,474 $3,619,284 </Table> Tax character of distributions paid during the year ended August 31, 2002 were: <Table> <Caption> TAX-EXEMPT LONG-TERM TOTAL INCOME ORDINARY INCOME CAPITAL GAINS DISTRIBUTIONS - ------------------ ------------------ ------------------ ------------------ $4,365,634 -- -- $4,365,634 </Table> For federal income tax purposes, the Series utilized approximately $19,000 of its capital loss carryforward to offset net taxable gains realized in the fiscal year ended August 31, 2003.

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.

The graph compares a $10,000 investment in the Dryden Municipal Series Fund/Florida Series (Class A shares) with a similar investment in the Lehman Brothers Municipal Bond Index by portraying the initial account values at the beginning of the ten-year period of Class A shares (August 31, 1993) and the account values at the end of the current fiscal year (August 31, 2003) as measured on a quarterly basis. For purposes of the graph, and unless otherwise indicated, it has been assumed that (a) the maximum applicable front-end sales charge was deducted from the initial $10,000 investment in Class A shares; (b) all recurring fees (including management fees) were deducted; and (c) all dividends and distributions were reinvested. The line graph provides information for Class A shares only. As indicated in the tables, performance for Class B, Class C, and Class Z shares will vary due to the differing charges and expenses applicable to each share class (as indicated in the following paragraphs). Without a distribution and service (12b-1) fee waiver of 0.05% for Class A shares, the returns for Class A shares shown in the graph and in the tables would have been lower. The returns on investment in the graph and in the tables do not reflect the deduction of taxes that a shareholder would pay on fund distributions or following the redemption of fund shares.

Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually. Class Z shares are not subject to a sales charge or 12b-1 fee.

JennisonDrydenMutualFunds Dear Shareholder, October 10, 2003 There have been welcome signs that the U.S. economy is growing again.

The economic picture continues to change, providing new opportunities and challenges. Regardless of the direction of financial markets, it is important to remember that a wise investor plans today for tomorrow's needs.

Dryden Municipal Series Fund/New Jersey Series 3 Investment Adviser's Report Market Overview and Performance Summary The municipal bond market repeatedly rallied, then sold off, which resulted in a 3.14% return for the fiscal year ended August 31, 2003, according to the Lehman Brothers Municipal Bond Index (the Index). The market's volatility largely reflected uncertainty about the prospects for economic growth in the United States. The outlook was cloudy because investors did not know how much the Federal Reserve (the Fed) would cut short-term interest rates in an effort to stimulate the sluggish economy. There was also concern that U.S. involvement in a war in Iraq might harm the U.S. economy. Our investment strategy aimed to provide the Series with the flexibility to readily respond to changing conditions in the municipal bond market. However, for the 12 months ended August 31, 2003, the Series' performance trailed its benchmark, the Index. This occurred because the Series invests in the New Jersey municipal bond sector, which underperformed the broader municipal bond market as measured by the Index. The Index also does not reflect the operating expenses of mutual funds. Compared to its peer group, which does take into account operating expenses, the Series' returns exceeded the Lipper New Jersey Municipal Debt Funds Average for the 12 months ended August 31, 2003. Early in our reporting period, municipal bonds gained in value to such an extent that we believed a correction in the market was virtually inevitable. When the equity market began to recover in October 2002, demand for municipal bonds faded temporarily and their prices plunged. The tax-exempt market was also pressured by a large amount of newly issued bonds at that time. The sell-off in municipal bonds soon turned into a rally. Investors paid higher prices (and accepted lower yields) for tax-exempt bonds because the Fed was expected to cut short-term rates with the goal of boosting economic growth. In November 2002, it reduced its target for the federal funds rate by half a percentage point to 1.25%. Concern about the economy occurred before and continued after the war in Iraq began in March 2003. Consequently, there was speculation in the financial markets that the Fed would aggressively reduce rates again or purchase U.S. Treasury securities, which would also exert downward pressure on the general level of interest rates. This factor helped the municipal bond rally remain on track for the most part until mid-June 2003. At that time, however, the municipal bond market began to sell off along with Treasurys. Economic data suggested that the Fed might not cut rates sharply when it met in late June. Indeed, it only lowered its target for the federal funds 4 Visit our website at www.jennisondryden.com rate by a quarter of a percentage point to 1%. During the remainder of the reporting period, municipal bond prices slid in July and stabilized in August. Municipal bond prices were hurt by data showing stronger economic growth, even though the job market remained weak. Credit Quality and Interest-Rate Sensitivity New Jersey's debt burden has risen in recent years. Nevertheless, we believe that the state's credit remains sound, with further improvement in store as economic growth picks up. During the reporting period, New Jersey general obligation bonds remained rated AA with a stable outlook by Standard & Poor's Ratings Group, and Aa2 with a negative outlook by Moody's Investors Service. Given the fiscal challenges facing New Jersey and the frequent changes in the level of interest rates, we continued to work toward achieving the right balance in the Series with regard to two important overlapping characteristics. The first was credit quality, which involves the Series' exposure to high- quality bonds versus low-quality bonds. The second was interest-rate sensitivity, which involves the Series' exposure to bonds with good potential for price appreciation versus bonds that behave defensively during a sell-off in the fixed income market. From the perspective of credit quality, bonds rated Aaa (both insured and uninsured) accounted for roughly 66% of the Series' net assets as of August 31, 2003. We emphasized Aaa-rated bonds because they tend to perform better than lower-quality bonds under challenging economic conditions. However, as accelerating economic growth increases demand for riskier assets, lower-quality bonds tend to outperform Aaa-rated municipal bonds. The Series had some exposure to bonds of below- investment-grade quality, which provided considerable interest income. In the volatile interest-rate environment, we maintained a barbell strategy that essentially focused on two types of bonds. One side of our barbell primarily emphasized Aaa-rated, insured zero coupon bonds, which are so named because they pay no interest and are sold at discount prices to make up for their lack of periodic interest payments. Zero coupon bonds are the most interest-rate-sensitive of all bonds, which enables them to perform better than other types of debt securities when interest rates decline and bond prices move higher. The other side of our barbell emphasized intermediate- term bonds whose higher coupon rates provided the Series with considerable interest income. These bonds are considered to have defensive characteristics as their prices tend to hold up relatively well when the municipal bond market sells off. The bonds are also attractive to investors because they provide solid income. Dryden Municipal Series Fund/New Jersey Series 5 Periodically readjusting our coupon barbell strategy was one way to change the Series' duration, which measures its sensitivity to fluctuations in the level of interest rates. In general, when we determined that there was a trend toward higher interest rates, we aimed to shorten the Series' duration to help protect its value as rising interest rates pushed municipal bond prices lower. On the other hand, we aimed to lengthen the Series' duration to help it benefit more fully when falling interest rates drove municipal bond prices higher. In general, we employed this tactic periodically once we determined that the decline in interest rates was indeed a trend rather than a temporary development.

Dryden Municipal Series Fund - New Jersey Series 17 <Page> Notes to Financial Statements Dryden Municipal Series Fund (the 'Fund'), formerly known as Prudential Municipal Series Fund is registered under the Investment Company Act of 1940, as an open-end management investment company. The Fund was organized as a Massachusetts business trust on May 18, 1984, and consists of six series. These financial statements relate only to New Jersey Series (the 'Series'). The financial statements of the other series are not presented herein. The assets of each series are invested in separate, independently managed portfolios. The Series commenced investment operations in March 1988. The Series is diversified and seeks to achieve its investment objective of obtaining the maximum amount of income exempt from federal and New Jersey state income taxes with the minimum of risk by investing in 'investment grade' tax-exempt securities whose ratings are within the four highest ratings categories by a nationally recognized statistical rating organization or, if not rated, are of comparable quality. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic or political developments in a specific state, industry or region. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund, and the Series, in the preparation of its financial statements. Securities Valuations: The Series values municipal securities (including commitments to purchase such securities on a 'when-issued' basis) on the basis of prices provided by a pricing service which uses information with respect to transactions in comparable securities and various relationships between securities in determining values. If market quotations are not readily available from such pricing service, a security is valued at its fair value as determined under procedures established by the Trustees. Securities, including options, futures contracts and options thereon, for which the primary market is on a national securities exchange, commodities exchange or board of trade are valued at the last sale price on such exchange or board of trade, on the date of valuation or, if there was no sale on such day, at the average of readily available closing bid and asked prices on such day or at the bid price in the absence of an asked price. Securities, including options, that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed to be over-the-counter, are valued at the average of the most recently quoted bid and asked prices provided by a principal market maker or dealer. 18 Visit our website at www.jennisondryden.com <Page> Short-term securities which mature in sixty days or less are valued at amortized cost, which approximates market value. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of the difference between the principal amount due at maturity and cost. Short-term securities which mature in more than sixty days are valued at current market quotations. Financial Futures Contracts: A financial futures contract is an agreement to purchase (long) or sell (short) an agreed amount of securities at a set price for delivery on a future date. Upon entering into a financial futures contract, the Series is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This amount is known as the 'initial margin.' Subsequent payments, known as 'variation margin,' are made or received by the Series each day, depending on the daily fluctuations in the value of the underlying security. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain or loss. When the contract expires or is closed, the gain or loss is realized and is presented in the Statement of Operations as net realized gain or loss on financial futures transactions. The Series invests in financial futures contracts in order to hedge its existing portfolio securities, or securities the Series intends to purchase, against fluctuations in value caused by changes in prevailing interest rates or market conditions. Should interest rates move unexpectedly, the Series may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets. Options: The Series may either purchase or write options in order to hedge against adverse market movements or fluctuations in value caused by changes in prevailing interest rates with respect to securities which the Series currently owns or intends to purchase. The Series' principal reason for writing options is to realize, through receipt of premiums, a greater current return than would be realized on the underlying security alone. When the Series purchases an option, it pays a premium and an amount equal to that premium is recorded as an asset. When the Series writes an option, it receives a premium and an amount equal to that premium is recorded as a liability. The asset or liability is adjusted daily to reflect the current market value of the option. If an option expires unexercised, the Series realizes a gain or loss to the extent of the premium received or paid. If an option is exercised, the premium received or paid is recorded as an adjustment to the proceeds from the sale or the cost of the purchase in determining whether the Series has realized a gain or loss. The difference between the premium and the amount received or paid on effecting a closing purchase or sale transaction is also treated as a realized gain or loss. Gain or loss on purchased options is included in net realized gain or loss Dryden Municipal Series Fund - New Jersey Series 19 <Page> on investment transactions. Gain or loss on written options is presented separately as net realized gain or loss on written option transactions. The Series, as writer of an option, may have no control over whether the underlying securities may be sold (called) or purchased (put). As a result, the Series bears the market risk of an unfavorable change in the price of the security underlying the written option. The Series, as purchaser of an option, bears the risk of the potential inability of the counterparties to meet the terms of their contracts. Interest Rate Swaps: The Series may enter into interest rate swaps. In a simple interest rate swap, one investor pays a floating rate of interest on a notional principal amount and receives a fixed rate of interest on the same notional principal amount for a specified period of time. Alternatively, an investor may pay a fixed rate and receive a floating rate. Interest rate swaps were conceived as asset/liability management tools. In more complex swaps, the notional principal amount may decline (or amortize) over time. During the term of the swap, changes in the value of the swap are recognized as unrealized gains or losses by 'marking-to-market' to reflect the market value of the swap. When the swap is terminated, the Series will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Series' basis in the contract, if any. The Series is exposed to credit loss in the event of non-performance by the other party to the interest rate swap. However, the Series does not anticipate non-performance by any counterparty. Written options, future contracts and swap contracts involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities. Inverse Floaters: The Series invests in variable rate securities commonly called 'inverse floaters'. The interest rates on these securities have an inverse relationship to the interest rate of other securities or the value of an index. Changes in interest rates on the other security or index inversely affect the rate paid on the inverse floater, and the inverse floater's price will be more volatile than that of a fixed-rate bond. Additionally, some of these securities contain a 'leverage factor' whereby the interest rate moves inversely by a 'factor' to the benchmark rate. Certain interest rate movements and other market factors can substantially affect the liquidity of inverse floating rate notes. Securities Transactions and Net Investment Income: Securities transactions are recorded on the trade date. Realized gains or losses on sales of securities are 20 Visit our website at www.jennisondryden.com <Page> calculated on the identified cost basis. Interest income, including amortization of premium and accretion of discount on debt securities, as required, is recorded on the accrual basis. Expenses are recorded on the accrual basis which may require the use of certain estimates by management. Net investment income or loss (other than distribution fees, which are charged directly to the respective class) and realized and unrealized gains or losses are allocated daily to each class of shares based upon the relative proportion of net assets of each class at the beginning of the day. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate taxpaying entity. It is the 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. Dividends and Distributions: The Series declares daily dividends from net investment income. Payment of dividends is made monthly. Distributions of net capital gains, if any, are made annually. Dividends and 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. Permanent book/tax differences relating to income and gains are reclassified to paid-in capital when they arise. Custody Fee Credits: The Fund has an arrangement with its custodian bank, whereby uninvested cash earns credits which reduce the fees charged by the custodian. The Series could have invested a portion of the cash utilized in connection with the expense offset arrangements in an income producing asset if it had not entered into such arrangements. 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'). The subadvisory agreement provides that PIM furnishes investment advisory services in connection with the management of the Series. In connection therewith, PIM is obligated to keep certain books and records of the Series. PI pays for the services of PIM, the compensation of officers of the Series, occupancy and certain clerical and bookkeeping costs of the Series. The Series bears all other costs and expenses. Dryden Municipal Series Fund - New Jersey Series 21 <Page> The management fee paid to PI is computed daily and payable monthly, at an annual rate of .50 of 1% of the average daily net assets of the Series. The Series has a distribution agreement with Prudential Investment Management Services LLC ('PIMS') which acts as distributor of the Series. The Series compensates PIMS for distributing and servicing the Series' Class A, Class B and Class C shares pursuant to plans of distribution (the 'Class A, B and C Plans'), regardless of expenses actually incurred by PIMS. The distribution fees are accrued daily and payable monthly. No distribution or service fees are paid to PIMS as distributor of the Class Z shares of the Series. Pursuant to the Class A, B and C Plans, the Series compensates PIMS for distribution-related activities at an annual rate of up to .30 of 1%, .50% of 1% and up to 1% of the average daily net assets of the Class A, B and C shares, respectively. PIMS contractually agreed to limit such fees to .25 of 1% and .75 of 1% of the Class A shares and Class C shares, respectively. PIMS advised the Series that it has received approximately $58,900 and $9,300 in front-end sales charges resulting from sales of Class A and Class C shares, respectively, during the year ended August 31, 2003. From these fees, PIMS paid such sales charges to affiliated broker-dealers, which in turn paid commissions to salespersons and incurred other distribution costs. PIMS has advised the Series that during the year ended August 31, 2003, it received approximately $45,200 and $1,800 in contingent deferred sales charges imposed upon certain redemptions by Class B and Class C shareholders, respectively. PI, PIMS and PIM are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). The Series, along with other affiliated registered investment companies (the 'Funds'), is a party to a syndicated credit agreement ('SCA') with a group of banks. For the year ended August 31, 2003, the SCA provides for a commitment of $800 million and allows the Funds to increase the commitment to $1 billion, if necessary.

DISTRIBUTIONS AND TAX INFORMATION In order to present undistributed net investment income or loss and accumulated net realized gains or losses on the Statement of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to paid-in-capital in excess of par, undistributed net investment income (loss) and accumulated net realized gain (loss) on investments. For the year ended August 31, 2003, the adjustments were to decrease undistributed net investment income by $62,980, increase accumulated net realized gain by $25,543 and increase paid-in capital by $37,437 primarily due to the difference in the treatment of accreting market discount between financial and tax reporting. Net investment income, net realized gains and net assets were not affected by this change. Tax character of distributions paid during the year ended August 31, 2003 were: <Table> <Caption> TAX-EXEMPT LONG-TERM TOTAL INCOME ORDINARY INCOME CAPITAL GAINS DISTRIBUTIONS - ------------------ ------------------ ------------------ ------------------ $7,583,873 $10,446 $718,852 $8,313,171 </Table> Tax character of distributions paid during the year ended August 31, 2002 were: <Table> <Caption> TAX-EXEMPT LONG-TERM TOTAL INCOME ORDINARY INCOME CAPITAL GAINS DISTRIBUTIONS - ------------------ ------------------ ------------------ ------------------ $8,429,294 $405,250 -- $8,834,544 </Table> As of August 31, 2003, the components of distributable earnings on a tax basis were $81,744 (includes a timing difference of $119,181 for dividends payable) and $1,471,694 of tax-exempt income and long-term capital gains, respectively. 24 Visit our website at www.jennisondryden.com <Page> The United States federal income tax basis of the Series' investments and the net unrealized appreciation as of August 31, 2003 were as follows: <Table> <Caption> TAX BASIS NET UNREALIZED OF INVESTMENTS APPRECIATION DEPRECIATION APPRECIATION - ------------------ ------------------ ------------------ ------------------ $164,696,374 $10,485,259 $731,902 $9,753,357 </Table> The difference between book and tax basis was primarily attributable to the difference in the treatment of accretion of market discount and deferred losses on wash sales.

Dryden Municipal Series Fund - New Jersey Series 35 <Page> Report of Independent Auditors To the Shareholders and Trustees of Dryden Municipal Series Fund In our opinion, the accompanying statement of assets and liabilities, including the portfolio 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 Dryden Municipal Series Fund (formerly, Prudential Municipal Series Fund), New Jersey Series (one of the portfolios constituting Dryden Municipal Series Fund, hereafter referred to as the 'Fund') at August 31, 2003, the results of its operations for the year then ended, the changes in its 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 August 31, 2003 by correspondence with the custodian and broker, provide a reasonable basis for our opinion.

The graph compares a $10,000 investment in the Dryden Municipal Series Fund/New Jersey Series (Class A shares) with a similar investment in the Lehman Brothers Municipal Bond Index by portraying the initial account values at the beginning of the ten-year period of Class A shares (August 31, 1993) and the account values at the end of the current fiscal year (August 31, 2003) as measured on a quarterly basis. For purposes of the graph, and unless otherwise indicated, it has been assumed that (a) the maximum applicable front-end sales charge was deducted from the initial $10,000 investment in Class A shares; (b) all recurring fees (including management fees) were deducted; and (c) all dividends and distributions were reinvested. The line graph provides information for Class A shares only. As indicated in the tables, performance for Class B, Class C, and Class Z shares will vary due to the differing charges and expenses applicable to each share class (as indicated in the following paragraphs). Without a distribution and service (12b-1) fee waiver of 0.05% for Class A shares, the returns for Class A shares shown in the graph and in the tables would have been lower. The returns on investment in the graph and in the tables do not reflect the deduction of taxes that a shareholder would pay on fund distributions or following the redemption of fund shares. Visit our website at www.jennisondryden.com The Lehman Brothers Municipal Bond Index is an unmanaged index of over 39,000 long-term investment-grade municipal bonds. It gives a broad look at how long-term investment-grade municipal bonds have performed. The Lehman Brothers Municipal Bond Index's total returns include the reinvestment of all dividends, but do not include the effects of sales charges, operating expenses of a mutual fund, or taxes. These returns would be lower if they included the effects of sales charges, operating expenses, or taxes. The securities that comprise the Lehman Brothers Municipal Bond Index may differ substantially from the securities in the Series. The Lehman Brothers Municipal Bond Index is not the only index that may be used to characterize performance of municipal bond funds. Other indexes may portray different comparative performance. Investors cannot invest directly in an index. The Series charges a maximum front-end sales charge of 3% for Class A shares and a 12b-1 fee of up to 0.30% annually. Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually. Class Z shares are not subject to a sales charge or 12b-1 fee. Without waiver of fees and/or expense subsidization, the Series' returns in the tables would have been lower, as indicated in parentheses.

JennisonDrydenMutualFunds Dear Shareholder, October 10, 2003 There have been welcome signs that the U.S. economy is growing again. Many corporate executives and investment research analysts are expecting profits to rise as well. However, jobs are not being created as quickly as in past recoveries, reminding us that the resumption of growth doesn't mean a return to an earlier time. The economic picture continues to change, providing new opportunities and challenges. Regardless of the direction of financial markets, it is important to remember that a wise investor plans today for tomorrow's needs. A broadly diversified investment portfolio will increase your chances of participating in positive changes and is also your best long-term defense against unexpected downturns.

Dryden Municipal Series Fund/New Jersey Money Market Series 3 Investment Adviser's Report Falling Rates Affected Money Market Funds The investment environment remained challenging during the New Jersey Money Market Series' fiscal year that began September 1, 2002. Municipal money market yields fell to very low levels, complicating the search for high- quality debt securities that provided attractive yields. Furthermore, the state of New Jersey continued to face tough economic times. Under these market conditions, we employed what we believed to be a conservative approach to security selection and interest- rate risk that aimed to enhance the Series' yield and maintain its net asset value (NAV) at $1.00 per share throughout the 12-month reporting period. The trend toward lower municipal money market yields reflected anticipation that the Federal Reserve (the Fed) might reduce short-term interest rates. The rate cuts in November 2002 and June 2003 lowered the target for the federal funds rate by three-quarters of a percentage point to 1%, its lowest level in many years. By cutting borrowing costs, the Fed hoped to stimulate growth in the United States despite a lingering sense of economic uncertainty caused at times by, among other things, a volatile stock market and geopolitical concerns. Timely Purchases Benefited the Series As part of our conservative investment strategy, the Series held high-quality fixed- and floating-rate debt securities of municipal entities such as cities, counties, and school districts. The Series' shorter-term securities provided the Series with some flexibility as their proceeds could be readily reinvested if attractive investment opportunities emerged. We also tried to take advantage of times when yields temporarily edged higher by locking in yields on longer-term municipal money market securities. For example, when stronger-than- expected economic data led to a brief upturn in yields in October 2002, we purchased debt securities that matured in September and October 2003. By investing in longer-term municipal money market securities, we helped the Series ride out the "January effect," a seasonal decline in yields that typically occurs in the first week of January as increased demand for municipal money market securities temporarily outstrips the supply. Taking Care of Shareholder Liquidity Needs Once the January effect was over, we continued to invest in longer- and shorter-term municipal money market securities. We bought notes that mature in December 2003 and February 2004, as well as debt securities that matured in April 2003. Proceeds from the securities that came due in April helped meet our shareholder liquidity needs that often increase during tax season. We also took advantage of attractive investment opportunities that emerged during tax time as other portfolio managers 4 Visit our website at www.jennisondryden.com sold securities to provide shareholders with cash to pay their taxes. Among our purchases were so-called "put" bonds that pay fixed interest rates for one year, after which investors will receive par and accrued interest for the bonds when they deliver them back for payment. An Emphasis on Adjustable-Rate Securities After tax season, we invested primarily in securities whose interest rates reset either on a daily or weekly basis. These bonds have a demand feature that allows investors, at their discretion, to turn the bonds in for cash that must be paid within one to five days. Consequently, they provided the Series with sufficient liquidity to cope with the volatile asset flows that can often occur during the period. Holding a combination of longer- and shorter-term municipal money market securities enabled the Series to ride out the "July effect," another seasonal decline in yields that typically occurs in the first week of July for the same reasons as the January effect. Economy Continued to Challenge New Jersey We remained very selective when buying municipal money market securities of issuers in New Jersey because the Garden State's debt burden has increased in recent years. Nevertheless, we believe that New Jersey's credit remains sound, with further improvement in store as economic growth picks up.

The Fund was organized as a Massachusetts business trust on May 18, 1984 and consists of six series. These financial statements relate to only New Jersey Money Market Series (the 'Series'). The financial statements of the other series are not presented herein. The assets of each series are invested in separate, independently managed portfolios. The Series commenced investment operations on December 3, 1990. The Series is nondiversified and seeks to achieve its investment objective of providing the highest level of income that is exempt from New Jersey state and federal income taxes with a minimum of risk by investing in 'investment grade' tax-exempt securities maturing within 13 months or less and whose ratings are within the two highest ratings categories by a nationally recognized statistical rating organization, or if not rated, are of comparable quality. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic developments in a specific state, industry or region. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund, and the Series, in the preparation of its financial statements. Securities Valuations: Portfolio securities of the Series are valued at amortized cost, which approximates market value. The amortized cost 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. If the amortized cost method is determined not to represent fair value, the fair value shall be determined by or under the direction of the Board of Trustees. Securities Transactions and Net 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 Series 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. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate taxpaying entity. It is the Series' policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment Dryden Municipal Series Fund - New Jersey Money Market Series 13 <Page> companies and to distribute all of its net income to shareholders. For this reason, no federal income tax provision is required. Dividends and distributions: The Series declares daily dividends from net investment income and net realized short-term gains. Payment of dividends is made monthly. Income distributions and capital gain distributions are determined in accordance with income tax regulations which may differ from generally accepted accounting principles. Custody Fee Credits: The Fund has an arrangement with its custodian bank, whereby uninvested cash earns credits which reduce the fees charged by the custodian. The Series could have invested a portion of the cash utilized in connection with the expense offset arrangements in an income producing asset if it had not entered into such arrangements. NOTE 2. AGREEMENTS The Fund has a management agreement with Prudential Investments LLC ('PI'). Pursuant to a subadvisory agreement between PI and Prudential Investment Management, Inc. ('PIM'), PIM furnishes investment advisory services in connection with the management of the Fund. Under the subadvisory agreement, PIM, subject to the supervision of PI, is responsible for managing the assets of each Series in accordance with its investment objective and policies. PI pays for the services of PIM, the cost of compensation of officers of the Series, occupancy and certain clerical and bookkeeping costs of the Series. The Series bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly, at an annual rate of .50 of 1% of the average daily net assets of the Series. The Series has a distribution agreement with Prudential Investment Management Services LLC ('PIMS'), which acts as the distributor of the Series. The Series compensates PIMS for distributing and servicing the Series' shares pursuant to a plan of distribution regardless of expenses actually incurred by PIMS. The Series pays PIMS for distributing and servicing the Series shares pursuant to the plan of distribution at an annual rate of .125 of 1% of the Series' average daily net assets. The distribution fee is accrued daily and payable monthly. PI, PIM and PIMS are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). 14 Visit our website at www.jennisondryden.com <Page> 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 Series transfer agent. During the year ended August 31, 2003, the Series incurred fees of approximately $44,900 for the services of PMFS. As of August 31, 2003, approximately $3,700 of such fees were due to PMFS. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to non-affiliates, where applicable. NOTE 4. DISTRIBUTIONS AND TAX INFORMATION For the years ended August 31, 2003 and August 31, 2002, the tax character of the dividends paid, as reflected in the Statement of Changes in Net Assets, of $1,066,152 and $2,412,225, respectively, were tax-exempt income. As of August 31, 2003, the accumulated undistributed earnings on a tax basis was $4,845 of tax-exempt income (includes a timing difference of $4,845 for dividends payable). NOTE 5. CAPITAL The Series offers Class A shares. The Series may also offer Class S shares. There are no Class S shares currently issued and outstanding.

JennisonDrydenMutualFunds Dear Shareholder, October 10, 2003 There have been welcome signs that the U.S. economy is growing again.

The average annual total returns do take into account applicable sales charges. Without the contractual distribution and service (12b-1) fee waiver of 0.05% and 0.25% for Class A and Class C shares respectively, the returns for these classes would have been lower. The Distributor's 12b-1 fee waiver of 0.25% for Class C shares continued through August 31, 2003. The Series charges a maximum front-end sales charge of 3% for Class A shares and a 12b-1 fee of up to 0.30% annually. In some circumstances, Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually.

Dryden Municipal Series Fund/New York Series 3 Investment Adviser's Report Market Overview and Performance Summary The municipal bond market repeatedly rallied, then sold off, which resulted in a 3.14% return for the fiscal year ended August 31, 2003, according to the Lehman Brothers Municipal Bond Index (the Index). The market's volatility largely reflected uncertainty about the prospects for economic growth in the United States. The outlook was cloudy because investors did not know how much the Federal Reserve (the Fed) would cut short-term interest rates in an effort to stimulate the sluggish economy. There was also concern that U.S. involvement in a war in Iraq might harm the U.S. economy. Our investment strategy aimed to provide the Series with the flexibility to readily respond to changing conditions in the municipal bond market. However, for the 12 months ended August 31, 2003, the Series' Class A shares trailed their benchmark, the Index. This occurred because the Series holds certain bonds that declined in value due to credit quality problems discussed later in this report. The Index also does not reflect the operating expenses of mutual funds. Compared to their peer group, which does take into account operating expenses, the Series' Class A shares posted a return that exceeded the Lipper New York Municipal Debt Funds Average for the 12 months ended August 31, 2003. Early in our reporting period, municipal bonds gained in value to such an extent that we believed a correction in the market was virtually inevitable. When the equity market began to recover in October 2002, demand for municipal bonds faded temporarily and their prices plunged. The tax-exempt market was also pressured by a large amount of newly issued bonds at that time. The sell-off in municipal bonds soon turned into a rally. Investors paid higher prices (and accepted lower yields) for tax-exempt bonds because the Fed was expected to cut short-term rates with the goal of boosting economic growth. In November 2002, it reduced its target for the federal funds rate by half a percentage point to 1.25%. Concern about the economy occurred before and continued after the war in Iraq began in March 2003. Consequently, there was speculation in the financial markets that the Fed would aggressively reduce rates again or purchase U.S. Treasury securities, which would also exert downward pressure on the general level of interest rates. This factor helped the municipal bond rally remain on track for the most part until mid-June 2003. At that time, however, the municipal bond market began to sell off along with Treasurys. Economic data suggested that the Fed might not cut rates sharply when it met in late June. Indeed, it only lowered its target for the federal funds rate by a quarter of a percentage point to 1%. During the remainder of the reporting 4 Visit our website at www.jennisondryden.com period, municipal bond prices slid in July and stabilized in August. Municipal bond prices were hurt by data showing stronger economic growth, even though the job market remained weak. Credit Quality and Interest-Rate Sensitivity Given the frequent changes in the level of interest rates and the fiscal challenges facing New York State and New York City, we continued to work toward achieving the right balance in the Series with regard to two important overlapping characteristics. The first was credit quality, which involves the Series' exposure to high-quality bonds versus low- quality bonds. The second was interest-rate sensitivity, which involves the Series' exposure to bonds with good potential for price appreciation versus bonds that behave defensively during a sell-off in the fixed income market. From the perspective of credit quality, bonds rated Aaa (both insured and uninsured) accounted for 43% of the Series' net assets as of August 31, 2003. We emphasized Aaa-rated bonds because they tend to perform better than lower-quality bonds under challenging economic conditions. However, as accelerating economic growth increases demand for riskier assets, lower-quality bonds tend to outperform Aaa- rated municipal bonds. The Series had some exposure to bonds of below-investment- grade quality. Some lower-quality bonds did not perform well. The Series holds bonds of the New York City Industrial Development Agency whose proceeds were used to refinance an earlier bond issue that funded construction of the Crowne Plaza- LaGuardia Hotel in New York City. A weak operating environment in the travel and leisure sector, due partly to the September 11 terrorist attacks in the United States, as well as the scheduled amortization of other debt left the limited partnership that leases the hotel with inadequate cash to pay scheduled debt service on the bonds. Therefore the bonds experienced a payment default and declined in value. This detracted from the Series' returns. The Series also held bonds of Scotia, New York Housing Authority for Coburg Village, a rental retirement center located in Saratoga County. The bonds defaulted as Coburg Village continues to suffer from a low occupancy rate that has resulted in inadequate cash flow to make timely interest and principal payments on the securities. Consequently, the bonds declined in value, which detracted from the Series' returns. In the volatile interest-rate environment, we maintained a barbell strategy that essentially focused on two types of bonds. One side of our barbell primarily emphasized Aaa-rated, insured zero coupon bonds, which are so named because Dryden Municipal Series Fund/New York Series 5 they pay no interest and are sold at discount prices to make up for their lack of periodic interest payments. Zero coupon bonds are the most interest-rate-sensitive of all bonds, which enables them to perform better than other types of debt securities when interest rates decline and bond prices move higher. The other side of our barbell emphasized intermediate- term bonds whose higher coupon rates provided the Series with considerable interest income. These bonds are considered to have defensive characteristics as their prices tend to hold up relatively well when the municipal bond market sells off. The bonds are also attractive to investors because they provide solid income. Periodically readjusting our coupon barbell strategy was one way to change the Series' duration, which measures its sensitivity to fluctuations in the level of interest rates. In general, when we determined that there was a trend toward higher interest rates, we aimed to shorten the Series' duration to help protect its value as rising interest rates pushed municipal bond prices lower. On the other hand, we aimed to lengthen the Series' duration to help it benefit more fully when falling interest rates drove municipal bond prices higher. In general, we employed this tactic periodically once we determined that the decline in interest rates was indeed a trend rather than a temporary development. Empire State, Big Apple Remain Under Pressure New York State continues to face difficult economic times. New York State's reliance on the personal income tax and the importance of the financial services industry (with its generally high levels of compensation but current distressed status) remains an inhibiting factor. However, despite the state's heavy debt burden and use of bond issuance to pay a portion of its budget deficit, New York State general obligation bonds maintained their rating of A2 with a stable outlook by Moody's Investors Service (Moody's). Standard & Poor's Ratings Group (S&P) rates the bonds AA with a negative outlook. New York City continues to struggle as a result of the terrorist attacks on September 11, 2001, and the sluggish regional and national economies. To balance its current budget, New York City has enacted spending reductions and revenue increases. Despite its problems, we believe that continuous sound financial management is a hallmark of New York City, which has been able to maintain its general obligation bond ratings at A2 with a negative outlook by Moody's, and single-A with a stable outlook by S&P. The Series has a considerable exposure to New York City general obligation bonds with above-market coupon rates because the Series stands to benefit if more of these bonds are refunded.

Dryden Municipal Series Fund - New York Series 15 <Page> Notes to Financial Statements Dryden Municipal Series Fund (the 'Fund'), formerly known as Prudential Municipal Series Fund is registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund was organized as a Massachusetts business trust on May 18, 1984 and consists of six series. These financial statements relate only to New York Series (the 'Series'). The financial statements of the other series are not presented herein. The assets of each series are invested in separate, independently managed portfolios. The Series commenced investment operations in September 1984. The Series is diversified and its investment objective is to maximize current income that is exempt from New York State, New York City and federal income taxes consistent with the preservation of capital, and in conjunction therewith, the Series may invest in debt securities with the potential for capital gain. The Series seeks to achieve the objective by investing primarily in New York State, municipal and local government obligations and obligations of other qualifying issuers. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic developments in a specific state, industry or region. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund, and the Series, in the preparation of its financial statements. Securities Valuations: The Series values municipal securities (including commitments to purchase such securities on a 'when-issued' basis) on the basis of prices provided by a pricing service which uses information with respect to transactions in comparable securities and various relationships between securities in determining values. If market quotations are not readily available from such pricing service, a security is valued at its fair value as determined under procedures established by the Trustees. Securities, including options, futures contracts and options thereon, for which the primary market is on a national securities exchange, commodities exchange or board of trade are valued at the last sale price on such exchange or board of trade, on the date of valuation or, if there was no sale on such day, at the average of readily available closing bid and asked prices on such day or at the bid price in the absence of an asked price. Securities, including options, that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed to be 16 Visit our website at www.jennisondryden.com <Page> over-the-counter, are valued at the average of the most recently quoted bid and asked prices provided by a principal market maker or dealer. Short-term securities which mature in sixty days or less are valued at amortized cost, which approximates market value. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of the difference between the principal amount due at maturity and cost. Short-term securities which mature in more than sixty days are valued at current market quotations. Financial Futures Contracts: A financial futures contract is an agreement to purchase (long) or sell (short) an agreed amount of securities at a set price for delivery on a future date. Upon entering into a financial futures contract, the Series is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This amount is known as the 'initial margin.' Subsequent payments, known as 'variation margin,' are made or received by the Series each day, depending on the daily fluctuations in the value of the underlying security. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain (loss). When the contract expires or is closed, the gain (loss) is realized and is presented in the Statement of Operations as net realized gain (loss) on financial futures transactions. The Series invests in financial futures contracts in order to hedge its existing portfolio securities, or securities the Series intends to purchase, against fluctuations in value caused by changes in prevailing interest rates or market conditions. Should interest rates move unexpectedly, the Series may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets. Options: The Series may either purchase or write options in order to hedge against adverse market movements or fluctuations in value caused by changes in prevailing interest rates with respect to securities which the Series currently owns or intends to purchase. The Series' principal reason for writing options is to realize, through receipt of premiums, a greater current return than would be realized on the underlying security alone. When the Series purchases an option, it pays a premium and an amount equal to that premium is recorded as an asset. When the Series writes an option, it receives a premium and an amount equal to that premium is recorded as a liability. The asset or liability is adjusted daily to reflect the current market value of the option. If an option expires unexercised, the Series realizes a gain or loss to the extent of the premium received or paid. If an option is exercised, the premium received or paid is recorded as an adjustment to the proceeds from the sale or the cost of the purchase in determining whether the Series has realized a Dryden Municipal Series Fund - New York Series 17 <Page> gain or loss. The difference between the premium and the amount received or paid on effecting a closing purchase or sale transaction is also treated as a realized gain or loss. Gain or loss on purchased options is included in net realized gain (loss) on investment transactions. Gain or loss on written options is presented separately as net realized gain (loss) on written option transactions. The Series, as writer of an option, may have no control over whether the underlying securities may be sold (called) or purchased (put). As a result, the Series bears the market risk of an unfavorable change in the price of the security underlying the written option. The Series, as purchaser of an option, bears the risk of the potential inability of the counterparties to meet the terms of their contracts. Interest Rate Swaps: The Series may enter into interest rate swaps. In a simple interest rate swap, one investor pays a floating rate of interest on a notional principal amount and receives a fixed rate of interest on the same notional principal amount for a specified period of time. Alternatively, an investor may pay a fixed rate and receive a floating rate. Interest rate swaps were conceived as asset/liability management tools. In more complex swaps, the notional principal amount may decline (or amortize) over time. During the term of the swap, changes in the value of the swap are recognized as unrealized gains or losses by 'marking-to-market' to reflect the market value of the swap. When the swap is terminated, the Series will record a realized gain(loss) equal to the difference between the proceeds from (or cost of) the closing transaction and the Series' basis in the contract, if any. The Series is exposed to credit loss in the event of non-performance by the other party to the interest rate swap. However, the Series does not anticipate non-performance by any counterparty. Written options, future contracts and swap contracts involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities. Inverse Floaters: The Series invests in variable rate securities commonly called 'inverse floaters'. The interest rates on these securities have an inverse relationship to the interest rate of other securities or the value of an index. Changes in interest rates on the other security or index inversely affect the rate paid on the inverse floater, and the inverse floater's price will be more volatile than that of a fixed-rate bond. Additionally, some of these securities contain a 'leverage factor' whereby the interest rate moves inversely by a 'factor' to the benchmark rate. Certain interest rate movements and other market factors can substantially affect the liquidity of inverse floating rate notes. 18 Visit our website at www.jennisondryden.com <Page> Securities Transactions and Net 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, as required, is recorded on the accrual basis. Expenses are recorded on the accrual basis which may require the use of certain estimates by management. Net investment income (loss) (other than distribution fees, which are charged directly to the respective class) and unrealized and realized gains (losses) are allocated daily to each class of shares based upon the relative proportion of net assets of each class at the beginning of the day. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate taxpaying entity. It is the Series' policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net income and capital gains, if any, to its shareholders. Therefore, no federal taxable income tax provision is required. Dividends and Distributions: The Series declares daily dividends from net investment income. Payment of dividends is made monthly. Distributions of net capital gains, if any, are made annually. Dividends and 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. Permanent book/tax differences relating to income and gains are reclassified to paid-in capital when they arise. Custody Fee Credits: The Fund has an arrangement with its custodian bank, whereby uninvested cash earns credits which reduce the fees charged by the custodian. The Series could have invested a portion of the cash utilized in connection with the expense offset arrangements in an income producing asset if it had not entered into such arrangements. 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'). The subadvisory agreement provides that PIM furnishes investment advisory services in connection with the management of the Series. In connection therewith, PIM is obligated to keep certain books and records of the Series. PI pays for the services of Dryden Municipal Series Fund - New York Series 19 <Page> PIM, the compensation of officers of the Series, occupancy and certain clerical and bookkeeping costs of the Series. The Series bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly, at an annual rate of .50 of 1% of the average daily net assets of the Series. The Series has a distribution agreement with Prudential Investment Management Services LLC ('PIMS'), which acts as the distributor of the Series. The Series compensates PIMS for distributing and servicing the Series' Class A, Class B and Class C shares, pursuant to a plan of distribution, (the 'Class A, B and C Plans'), regardless of expenses actually incurred by PIMS. The distribution fees are accrued daily and payable monthly. No distribution or service fees are paid to PIMS as distributor of the Class Z shares of the Series. Pursuant to the Class A, B and C Plans, the Series compensates PIMS for distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1% and up to 1% of the average daily net assets of the Class A, B and C shares, respectively. PIMS contractually agreed to limit such fees to .25 of 1% and .75 of 1% of the Class A shares and Class C shares, respectively. PIMS has advised the Series that it received approximately $45,900 and $6,700 in front-end sales charges resulting from sales of Class A and Class C shares, respectively during the year ended August 31, 2003. From these fees, PIMS paid such sales charges to dealers, which in turn paid commissions to salespersons and incurred other distribution costs. PIMS has advised the Series that for the year ended August 31, 2003, it received approximately $52,300 and $2,700 in contingent deferred sales charges imposed upon certain redemptions by Class B and C shareholders, respectively. PI, PIM and PIMS are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). The Series, along with other affiliated registered investment companies (the 'Funds'), is a party to a syndicated credit agreement ('SCA') with a group of banks.

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.

The graph compares a $10,000 investment in the Dryden Municipal Series Fund/New York Series (Class A shares) with a similar investment in the Lehman Brothers Municipal Bond Index by portraying the initial account values at the beginning of the ten-year period of Class A shares (August 31, 1993) and the account values at the end of the current fiscal year (August 31, 2003) as measured on a quarterly basis. For purposes of the graph, and unless otherwise indicated, it has been assumed that (a) the maximum applicable front-end sales charge was deducted from the initial $10,000 investment in Class A shares; (b) all recurring fees (including management fees) were deducted; and (c) all dividends and distributions were reinvested. The line graph provides information for Class A shares only. As indicated in the tables, performance for Class B, Class C, and Class Z shares will vary due to the differing charges and expenses applicable to each share class (as indicated in the following paragraphs). Without a distribution and service (12b-1) fee waiver of 0.05% for Class A shares, the returns for Class A shares shown in the graph and in the tables would have been lower. The returns on investment in the graph and in the tables do not reflect the deduction of taxes that a shareholder would pay on fund distributions or following the redemption of fund shares. Visit our website at www.jennisondryden.com The Lehman Brothers Municipal Bond Index is an unmanaged index of over 39,000 long-term investment-grade municipal bonds. It gives a broad look at how long-term investment-grade municipal bonds have performed. The Lehman Brothers Municipal Bond Index's total returns include the reinvestment of all dividends, but do not include the effects of sales charges, operating expenses of a mutual fund, or taxes. These returns would be lower if they included the effects of sales charges, operating expenses, or taxes. The securities that comprise the Lehman Brothers Municipal Bond Index may differ substantially from the securities in the Series. The Lehman Brothers Municipal Bond Index is not the only index that may be used to characterize performance of municipal bond funds. Other indexes may portray different comparative performance. Investors cannot invest directly in an index. The Series charges a maximum front-end sales charge of 3% for Class A shares and a 12b-1 fee of up to 0.30% annually. Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually. Class Z shares are not subject to a sales charge or 12b-1 fee. Without waiver of fees and/or expense subsidization, the Series' returns in the tables would have been lower, as indicated in parentheses.

JennisonDrydenMutualFunds Dear Shareholder, October 10, 2003 There have been welcome signs that the U.S. economy is growing again. Many corporate executives and investment research analysts are expecting profits to rise as well. However, jobs are not being created as quickly as in past recoveries, reminding us that the resumption of growth doesn't mean a return to an earlier time. The economic picture continues to change, providing new opportunities and challenges. Regardless of the direction of financial markets, it is important to remember that a wise investor plans today for tomorrow's needs. A broadly diversified investment portfolio will increase your chances of participating in positive changes and is also your best long-term defense against unexpected downturns.

JennisonDryden funds are managed by Prudential Investment Management's public equity and fixed-income asset management businesses.

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. Sincerely, Judy A.

Dryden Municipal Series Fund/New York Money Market Series 3 Investment Adviser's Report Falling Rates Affected Money Market Funds The investment environment remained challenging during the New York Money Market Series' fiscal year that began September 1, 2002. Municipal money market yields fell to very low levels, complicating the search for high-quality debt securities that provided attractive yields. Furthermore, New York State and New York City continued to face tough economic times. Under these market conditions, we employed what we believed to be a conservative approach to security selection and interest-rate risk that aimed to enhance the Series' yield and maintain its net asset value (NAV) at $1 per share throughout the 12-month reporting period. The trend toward lower municipal money market yields reflected anticipation that the Federal Reserve (the Fed) would reduce short-term interest rates. The rate cuts in November 2002 and June 2003 lowered the target for the federal funds rate by three-quarters of a percentage point to 1%, its lowest level in many years. By cutting borrowing costs, the Fed hoped to stimulate growth in the United States despite a lingering sense of economic uncertainty caused at times by, among other things, a volatile stock market and geopolitical concerns. Timely Purchases Benefited the Series As part of our conservative investment strategy, the Series held high-quality fixed- and floating-rate debt securities of various municipal entities such as cities, counties, and school districts. The Series' holdings were diversified with respect to maturity sectors. For example, when stronger-than-expected economic data led to a brief upturn in yields in October 2002, we took advantage of the situation by locking in yields on tax-exempt commercial paper that matured in February 2003 and bonds that will mature in November 2003. In addition, we bought so-called "put" bonds that pay fixed interest rates for one year, after which investors will receive par and accrued interest for the bonds when they deliver them back for payment. By purchasing securities that matured after early January 2003, we helped the Series to ride out the "January effect," a seasonal decline in yields that typically occurs in the first week of January as increased demand for municipal money market securities temporarily outstrips the supply. Investing in a Flat-Yield-Curve Environment In early 2003, once the January effect was over, we were reluctant to invest in one-year securities because of the comparatively flat slope of the money market yield curve. (The money market yield curve resembles a line graph that depicts yields on securities that mature from one day through 13 months.) Instead, we focused on the short end of the yield curve by investing in securities whose interest rates were reset on a daily or weekly basis. By tax time, we purchased pre-refunded bonds (the bonds 4 Visit our website at www.jennisondryden.com were backed by U.S. government securities), bond anticipation notes, and tax-exempt commercial paper that matured in mid-July and August 2003. Our purchases helped the Series ride out the "July effect," another seasonal decline in yields that typically occurs in the first week of July for the same reasons as the January effect. Finding Attractive Value in "Put" Bonds Prior to the short-term rate cut in late June, we shifted our emphasis back to the one-year maturity sector by investing in more annual "put" bonds. Overall, we targeted high-quality securities that yielded 1% or better. We were rightly concerned that the general level of municipal short-term yields might soon slide well below 1% due to speculation in the financial markets that the Fed might ease monetary policy by as much as half a percentage point in June. (It actually cut short-term rates by a quarter of a percentage point at that time.) After the change in monetary policy, we invested primarily in securities whose rates reset on a daily or weekly basis and tax-exempt commercial paper that matured in one to three months. In our opinion, it was no longer advantageous to lock in yields in the one-year maturity sector because we believed the Fed might be finished easing monetary policy for this interest-rate cycle. Empire State, Big Apple Remain Under Pressure We remained very selective when purchasing municipal money market securities of issuers in New York State as difficult economic conditions continued. Reliance on personal income tax and the importance of the financial services industry (with its generally high levels of compensation, but currently distressed status) remains an inhibiting factor. However, despite the Empire State's heavy debt burden and use of bond issuance to pay a portion of its budget deficit, its long-term general obligation bonds are still rated A2 with a stable outlook by Moody's Investors Service (Moody's). They are rated AA with a negative outlook by Standard & Poor's Ratings Group (S&P). New York City continues to struggle as a result of the terrorist attacks on September 11, 2001 and the sluggish regional and national economies. To balance its current budget, New York City has enacted spending reductions and revenue increases. New York City has been able to maintain its long-term general obligation bond ratings at A2 with a negative outlook by Moody's and single-A with a stable outlook by S&P.

The Fund was organized as a Massachusetts business trust on May 18, 1984 and consists of six series. These financial statements relate only to New York Money Market Series (the 'Series'). The financial statements of the other series are not presented herein. The assets of each series are invested in separate, independently managed portfolios. The Series commenced investment operations in April 1985. The Series is diversified and seeks to achieve its investment objective of providing the highest level of income that is exempt from New York State, New York City and federal income taxes with a minimum of risk by investing in 'investment grade' tax-exempt securities having a maturity of 13 months or less whose ratings are within the two highest ratings categories by two nationally recognized statistical rating organizations, or if not rated, are of comparable quality. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic developments in a specific state, industry or region. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund, and the Series, in the preparation of its financial statements. Securities Valuations: Portfolio securities of the Series are valued at amortized cost, which approximates market value. The amortized cost 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. If the amortized cost method is determined not to represent fair value, the fair value shall be determined by or under the direction of the Board of Trustees. Securities Transactions and Net 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 Series 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. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate taxpaying entity. It is the Series' policy to continue to meet the requirements of the Internal Revenue Code applicable to regulated investment Dryden Municipal Series Fund - New York Money Market Series 15 <Page> 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. Dividends and Distributions: The Series declares daily dividends from net investment income and net realized short-term gains. Payment of dividends is made monthly. Income distributions and capital gain distributions are determined in accordance with income tax regulations, which may differ from generally accepted accounting principles. Custody Fee Credits: The Fund has an arrangement with its custodian bank, whereby uninvested cash earns credits which reduce the fees charged by the custodian. The Series could have invested a portion of the cash utilized in connection with the expense offset arrangements in an income producing asset if it had not entered into such arrangements. NOTE 2. AGREEMENTS The Fund has a management agreement with Prudential Investments LLC ('PI' or 'Manager'). Pursuant to a subadvisory agreement between PI and Prudential Investment Management, Inc. ('PIM' or 'Subadviser'), PIM furnishes investment advisory services in connection with the management of the Fund. Under the subadvisory agreement, PIM, subject to the supervision of PI, is responsible for managing the assets of each Series in accordance with its investment objective and policies. PI pays for the services of PIM, the cost of compensation of officers of the Series, occupancy and certain clerical and bookkeeping costs of the Series. The Series bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly, at an annual rate of .50 of 1% of the average daily net assets of the Series. The Series has a distribution agreement with Prudential Investment Management Services LLC ('PIMS') which acts as the distributor of the Series. The Series compensates PIMS for distributing and servicing the Series' shares pursuant to a plan of distribution regardless of expenses actually incurred by PIMS. The Series pays PIMS for distributing and servicing the Series' shares pursuant to the plan of distribution at an annual rate of .125 of 1% of the Series' average daily net assets. The distribution fee is accrued daily and payable monthly. PI, PIM and PIMS are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). 16 Visit our website at www.jennisondryden.com <Page> 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 and during the year ended August 31, 2003, the Series incurred fees of approximately $71,800 for the services of PMFS. As of August 31, 2003, approximately $5,500 of such fees were due to PMFS. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to non-affiliates, where applicable. NOTE 4. DISTRIBUTIONS AND TAX INFORMATION For the years ended August 31, 2003 and August 31, 2002, the tax character of the dividends paid, as reflected in the Statement of Changes in Net Assets, of $2,642,671 and $4,677,390, respectively, were tax-exempt income and $228,880 and $304,798, respectively, were taxable ordinary income.

JennisonDrydenMutualFunds Dear Shareholder, October 10, 2003 There have been welcome signs that the U.S. economy is growing again.

The economic picture continues to change, providing new opportunities and challenges. Regardless of the direction of financial markets, it is important to remember that a wise investor plans today for tomorrow's needs.

The average annual total returns do take into account applicable sales charges. Without the contractual distribution and service (12b-1) fee waiver of 0.05% and 0.25% for Class A and Class C shares respectively, the returns for these classes would have been lower. The Distributor's 12b-1 fee waiver of 0.25% for Class C shares continued through August 31, 2003. The Series charges a maximum front-end sales charge of 3% for Class A shares and a 12b-1 fee of up to 0.30% annually. In some circumstances, Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually.

Dryden Municipal Series Fund/Pennsylvania Series 3 Investment Adviser's Report Market Overview and Performance Summary The municipal bond market repeatedly rallied, then sold off, which resulted in a 3.14% return for the fiscal year ended August 31, 2003, according to the Lehman Brothers Municipal Bond Index (the Index). The market's volatility largely reflected uncertainty about the prospects for economic growth in the United States. The outlook was cloudy because investors did not know how much the Federal Reserve (the Fed) would cut short-term interest rates in an effort to stimulate the sluggish economy. There was also concern that U.S. involvement in a war in Iraq might harm the U.S. economy. Our investment strategy aimed to provide the Series with the flexibility to readily respond to changing conditions in the municipal bond market. However, for the 12 months ended August 31, 2003, the Series' Class A shares trailed their benchmark, the Index. This occurred because the Series held certain bonds that declined in value due to credit quality problems discussed later in this report. The Index also does not reflect the operating expenses of mutual funds. Compared to their peer group, which does take into account operating expenses, the Series' Class A shares posted a return that exceeded the Lipper Pennsylvania Municipal Debt Funds Average for the 12 months ended August 31, 2003. Early in our reporting period, municipal bonds gained in value to such an extent that we believed a correction in the market was virtually inevitable. When the equity market began to recover in October 2002, demand for municipal bonds faded temporarily and their prices plunged. The tax-exempt market was also pressured by a large amount of newly issued bonds at that time. The sell-off in municipal bonds soon turned into a rally. Investors paid higher prices (and accepted lower yields) for tax-exempt bonds because the Fed was expected to cut short-term rates with the goal of boosting economic growth. In November 2002, it reduced its target for the federal funds rate by half a percentage point to 1.25%. Concern about the economy occurred before and continued after the war in Iraq began in March 2003. Consequently, there was speculation in the financial markets that the Fed would aggressively reduce rates again or purchase U.S. Treasury securities, which would also exert downward pressure on the general level of interest rates. This factor helped the municipal bond rally remain on track for the most part until mid-June 2003. At that time, however, the municipal bond market began to sell off along with Treasurys. Economic data suggested that the Fed might not cut rates sharply when it met in late June. Indeed, it only lowered its target for the federal funds rate by a quarter of a percentage point to 1%. For the rest of the reporting period, 4 Visit our website at www.jennisondryden.com municipal bond prices slid in July and stabilized in August. Municipal bond prices were hurt by signs of stronger economic growth, even though the job market remained weak. Credit Quality and Interest-Rate Sensitivity Despite Pennsylvania's historically conservative financial practices, the state faced fiscal challenges during the reporting period. In light of this and frequent changes in the level of interest rates, we continued to work toward achieving the right balance in the Series with regard to two important overlapping characteristics. The first was credit quality, which involves the Series' exposure to high- quality bonds versus low-quality bonds. The second was interest-rate sensitivity, which involves the Series' exposure to bonds with good potential for price appreciation versus bonds that behave defensively during a sell-off in the fixed income market. From the perspective of credit quality, bonds rated Aaa (both insured and uninsured) accounted for roughly 62% of the Series' net assets as of August 31, 2003. We emphasized Aaa-rated bonds because they tend to perform better than lower-quality bonds under challenging economic conditions. However, as accelerating economic growth increases demand for riskier assets, lower-quality bonds tend to outperform Aaa-rated municipal bonds. The Series had some exposure to bonds of below- investment-grade quality. Among the Series' holdings that performed poorly were bonds of the Delaware County Authority for Dunwoody Village, a life-care facility located in Newtown, Pennsylvania. Standard & Poor's Ratings Group downgraded the bonds from single-A to A-minus, citing such factors as a two-year decline in operating performance driven by higher staffing and insurance costs and delays in filling expansion units. The bonds declined in value and detracted from the Series' return. In the volatile interest-rate environment, we maintained a barbell strategy that essentially focused on two types of bonds. One side of our barbell primarily emphasized Aaa-rated, insured zero coupon bonds, which are so named because they pay no interest and are sold at discount prices to make up for their lack of periodic interest payments. Zero coupon bonds are the most interest-rate-sensitive of all bonds, which enables them to perform better than other types of debt securities when interest rates decline and bond prices move higher. The other side of our barbell emphasized intermediate- term bonds whose higher coupon rates provided the Series with considerable interest income. These bonds are considered to have defensive characteristics, as their prices tend to hold up relatively well when the municipal bond market sells off. The bonds are also attractive to investors because they provide solid income. Dryden Municipal Series Fund/Pennsylvania Series 5 Periodically readjusting our coupon barbell strategy was one way to change the Series' duration, which measures its sensitivity to fluctuations in the level of interest rates. In general, when we determined that there was a trend toward higher interest rates, we aimed to shorten the Series' duration to help protect its value as rising interest rates pushed municipal bond prices lower. On the other hand, we aimed to lengthen the Series' duration to help it benefit more fully when falling interest rates drove municipal bond prices higher. In general, we employed this tactic periodically once we determined that the decline in interest rates was indeed a trend rather than a temporary development.

Dryden Municipal Series Fund - Pennsylvania Series 15 <Page> Notes to Financial Statements Dryden Municipal Series Fund (the 'Fund'), formerly known as Prudential Municipal Series Fund, is registered under the Investment Company Act of 1940 as an open-end management investment company. The Fund was organized as a Massachusetts business trust on May 18, 1984 and consists of six series. These financial statements relate only to Pennsylvania Series (the 'Series'). The financial statements of the other series are not presented herein. The assets of each series are invested in separate, independently managed portfolios. The Series commenced investment operations on April 3, 1987. The Series' investment objective is to maximize current income that is exempt from Commonwealth of Pennsylvania personal income tax and federal income tax, consistent with the preservation of capital. This means the Series invests at least 80% of the Series' investments in Pennsylvania state and local municipal bonds, which are debt obligations or fixed income securities, including notes, commercial paper and other securities, as well as obligations of other issuers (such as issuers located in Puerto Rico, the Virgin Islands and Guam) that pay interest income that is tax exempt from those taxes. The ability of the issuers of the securities held by the Series to meet their obligations may be affected by economic or political developments in a specific state, industry or region. NOTE 1. ACCOUNTING POLICIES The following is a summary of significant accounting policies followed by the Fund, and the Series, in the preparation of its financial statements. Securities Valuations: The Series values municipal securities (including commitments to purchase such securities on a 'when-issued' basis) on the basis of prices provided by a pricing service which uses information with respect to transactions in comparable securities and various relationships between securities in determining values. If market quotations are not readily available from such pricing service, a security is valued at its fair value as determined under procedures established by the Trustees. Securities, including options, futures contracts and options thereon, for which the primary market is on a national securities exchange, commodities exchange or board of trade are valued at the last sale price on such exchange or board of trade, on the date of valuation or, if there was no sale on such day, at the average of readily available closing bid and asked prices on such day or at the bid price in the absence of an asked price. 16 Visit our website at www.jennisondryden.com <Page> Securities, including options, that are actively traded in the over-the-counter market, including listed securities for which the primary market is believed to be over-the-counter, are valued at the average of the most recently quoted bid and asked prices provided by a principal market maker or dealer. Short-term securities which mature in sixty days or less are valued at amortized cost, which approximates market value. The amortized cost method involves valuing a security at its cost on the date of purchase and thereafter assuming a constant amortization to maturity of the difference between the principal amount due at maturity and cost. Short-term securities which mature in more than sixty days are valued at current market quotations. Financial Futures Contracts: A financial futures contract is an agreement to purchase (long) or sell (short) an agreed amount of securities at a set price for delivery on a future date. Upon entering into a financial futures contract, the Series is required to pledge to the broker an amount of cash and/or other assets equal to a certain percentage of the contract amount. This amount is known as the 'initial margin.' Subsequent payments, known as 'variation margin,' are made or received by the Series each day, depending on the daily fluctuations in the value of the underlying security. Such variation margin is recorded for financial statement purposes on a daily basis as unrealized gain or loss. When the contract expires or is closed, the gain or loss is realized and is presented in the Statement of Operations as net realized gain or loss on financial futures transactions. The Series invests in financial futures contracts in order to hedge its existing portfolio securities, or securities the Series intends to purchase, against fluctuations in value caused by changes in prevailing interest rates or market conditions. Should interest rates move unexpectedly, the Series may not achieve the anticipated benefits of the financial futures contracts and may realize a loss. The use of futures transactions involves the risk of imperfect correlation in movements in the price of futures contracts, interest rates and the underlying hedged assets. Options: The Series may either purchase or write options in order to hedge against adverse market movements or fluctuations in value caused by changes in prevailing interest rates with respect to securities which the Series currently owns or intends to purchase. The Series' principal reason for writing options is to realize, through receipt of premiums, a greater current return than would be realized on the underlying security alone. When the Series purchases an option, it pays a premium and an amount equal to that premium is recorded as an asset. When the Series writes an option, it receives a premium and an amount equal to that premium is recorded as a liability. The asset or liability is adjusted daily to reflect the current market value of the option. If an option expires unexercised, the Series realizes a gain or loss to the extent of the premium received or paid. If an option is exercised, Dryden Municipal Series Fund - Pennsylvania Series 17 <Page> the premium received or paid is recorded as an adjustment to the proceeds from the sale or the cost of the purchase in determining whether the Series has realized a gain or loss. The difference between the premium and the amount received or paid on effecting a closing purchase or sale transaction is also treated as a realized gain or loss. Gain or loss on purchased options is included in net realized gain or loss on investment transactions. Gain or loss on written options is presented separately as net realized gain or loss on written option transactions. The Series, as writer of an option, may have no control over whether the underlying securities may be sold (called) or purchased (put). As a result, the Series bears the market risk of an unfavorable change in the price of the security underlying the written option. The Series, as purchaser of an option, bears the risk of the potential inability of the counterparties to meet the terms of their contracts. Interest Rate Swaps: The Series may enter into interest rate swap agreements. In a simple interest rate swap, one investor pays a floating rate of interest on a notional principal amount and receives a fixed rate of interest on the same notional principal amount for a specified period of time. Alternatively, an investor may pay a fixed rate and receive a floating rate. Interest rate swaps were conceived as asset/liability management tools. In more complex swaps, the notional principal amount may decline (or amortize) over time. During the term of the swap, changes in the value of the swap are recognized as unrealized gains or losses by 'marking-to-market' to reflect the market value of the swap. When the swap is terminated, the Series will record a realized gain (loss) equal to the difference between the proceeds from (or cost of) the closing transaction and the Series' basis in the contract, if any. The Series is exposed to credit loss in the event of non-performance by the other party to the interest rate swap. However, the Series does not anticipate non-performance by any counterparty. Written options, swap contracts and futures contracts involve elements of both market and credit risk in excess of the amounts reflected on the Statement of Assets and Liabilities. Inverse Floaters: The Series invests in variable rate securities commonly called 'inverse floaters'. The interest rates on these securities have an inverse relationship to the interest rate of other securities or the value of an index. Changes in interest rates on the other security or index inversely affect the rate paid on the inverse floater, and the inverse floater's price will be more volatile than that of a fixed-rate bond. Additionally, some of these securities contain a 'leverage factor' whereby the interest rate moves inversely by a 'factor' to the benchmark rate. Certain interest 18 Visit our website at www.jennisondryden.com <Page> rate movements and other market factors can substantially affect the liquidity of inverse floating rate notes. Securities Transactions and Net Investment Income: Securities transactions are recorded on the trade date. Realized gains or 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, as required, is recorded on the accrual basis. Expenses are recorded on the accrual basis which may require the use of certain estimates by management. Net investment income or loss (other than distribution fees, which are charged directly to the respective class) and unrealized and realized gains or losses are allocated daily to each class of shares based upon the relative proportion of net assets of each class at the beginning of the day. Federal Income Taxes: For federal income tax purposes, each series in the Fund is treated as a separate tax-paying entity. It is the 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. Dividends and Distributions: The Series declares daily dividends from net investment income. Payment of dividends is made monthly. Distributions of net capital gains, if any, are made annually. Dividends and 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. Permanent book/tax differences relating to income and gains are reclassified to paid-in capital when they arise. Custody Fee Credits: The Fund has an arrangement with its custodian bank, whereby uninvested cash earns credits which reduce the fees charged by the custodian. The Series could have invested a portion of the cash utilized in connection with the expense offset arrangements in an income producing asset if it had not entered into such arrangements. 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 subadvisor's performance of such services. PI has entered into a subadvisory agreement with Prudential Investment Management, Inc. ('PIM'). The subadvisory agreement provides that PIM furnishes investment advisory services in Dryden Municipal Series Fund - Pennsylvania Series 19 <Page> connection with the management of the Series. In connection therewith, PIM is obligated to keep certain books and records of the Series. PI pays for the services of PIM, the compensation of officers of the Series, occupancy and certain clerical and bookkeeping costs of the Series. The Series bears all other costs and expenses. The management fee paid to PI is computed daily and payable monthly, at an annual rate of .50 of 1% of the average daily net assets of the Series. The Series has a distribution agreement with Prudential Investment Management Services LLC ('PIMS'), which acts as the distributor of the Series. The Series compensated PIMS for distributing and servicing the Series' Class A, Class B and Class C shares, pursuant to plans of distribution (the 'Class A, B and C Plans'), regardless of expenses actually incurred by PIMS. The distribution fees are accrued daily and payable monthly. No distribution or service fees are paid to PIMS as distributor of the Class Z shares of the Fund. Pursuant to the Class A, B and C Plans, the Series compensates PIMS for distribution-related activities at an annual rate of up to .30 of 1%, .50 of 1% and up to 1%, of the average daily net assets of the Class A, B and C shares, respectively. PIMS contractually agreed to limit such fees to .25 of 1% and .75 of 1% of the Class A shares and Class C shares, respectively. PIMS has advised the Series that they have received approximately $61,000 and $4,800 in front-end sales charges resulting from sales of Class A and Class C shares, respectively during the year ended August 31, 2003. From these fees, PIMS paid such sales charges to affiliated broker-dealers, which in turn paid commissions to salespersons and incurred other distribution costs. PIMS has advised the Series that for the year ended August 31, 2003, they received approximately $57,700 and $3,300 in contingent deferred sales charges imposed upon certain redemptions by Class B and Class C shareholders, respectively. PI, PIMS and PIM are indirect, wholly-owned subsidiaries of Prudential Financial, Inc. ('Prudential'). The Series, along with other affiliated registered investment companies (the 'Funds'), is a party to a syndicated credit agreement ('SCA') with a group of banks. For the year ended August 31, 2003, the SCA provides for a commitment of $800 million and allows the Funds to increase the commitment to $1 billion, if necessary. Interest on any borrowings under the SCA will be incurred at market rates. The Funds pay a commitment fee of .08 of 1% of the unused portion of the SCA. The commitment fee is accrued and paid quarterly and is allocated to the Funds pro rata based on net assets. The purpose of the SCA is to serve as an alternative source of funding for capital share 20 Visit our website at www.jennisondryden.com <Page> redemptions. The expiration date of the SCA was May 2, 2003. On May 2, 2003, the SCA was renewed under the same terms and conditions ('May 2003 renewal'). The expiration date of the May 2003 renewal is April 30, 2004. The Series did not borrow any amounts pursuant to the SCA during the year ended August 31, 2003. 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 August 31, 2003, the Series incurred fees of approximately $65,100 for the services of PMFS. As of August 31, 2003, approximately $5,300 of such fees were due to PMFS. Transfer agent fees and expenses in the Statement of Operations include certain out-of-pocket expenses paid to non-affiliates, where applicable. The Series pays networking fees to affiliated and unaffiliated broker/dealers. These networking fees are payments made to broker/dealers that clear mutual fund transactions through a national clearing system. The Series incurred approximately $6,300 in total networking fees of which the amount relating to the services of Wachovia Securities, LLC ('Wachovia') and Prudential Securities, Inc. ('PSI'), affiliates of PI, was approximately $5,300 for the year ended August 31, 2003. Prior to July 1, 2003, PSI was an indirect, wholly-owned subsidiary of Prudential. As of August 31, 2003, approximately $400 of such fees were due to Wachovia. These amounts are included in transfer agent's fees and expenses in the Statement of Operations. NOTE 4. PORTFOLIO SECURITIES Purchases and sales of portfolio securities of the Series, excluding short-term investments, for the year ended August 31, 2003, were $68,888,206 and $74,335,962 respectively. During the year ended August 31, 2003, the Series entered into financial futures contracts. Details of outstanding contracts at year end are as follows: <Table> <Caption> VALUE AT VALUE AT UNREALIZED NUMBER OF EXPIRATION AUGUST 31, TRADE APPRECIATION CONTRACTS TYPE DATE 2003 DATE (DEPRECIATION) - --------- ------------------- ----------------- ----------- ----------- ---------------- Long positions: 30 10 yr.

DISTRIBUTIONS AND TAX INFORMATION In order to present undistributed net investment income or loss and accumulated net realized gains or losses on the Statement of Assets and Liabilities that more closely represent their tax character, certain adjustments have been made to paid-in-capital in excess of par, undistributed net investment income or loss and accumulated net realized gain or loss on investments. For the year ended August 31, 2003, the adjustments were to decrease accumulated net realized gain by $202,617, increase undistributed net investment income by $246,821, and decrease paid-in capital by $44,204 primarily due to the difference in the treatment of accreting market discount between financial and tax reporting. Net investment income, net realized gains and net assets were not affected by this change. For the year ended August 31, 2003, the tax character of dividends paid, as reflected in the Statement of Changes in Net Assets, was $6,608,102 and $345,768 tax-exempt income and long-term capital gains, respectively. For the year ended August 31, 2002, the tax character of dividends paid $7,627,546 and $42,711 tax-exempt income and ordinary income, respectively. As of August 31, 2003, the accumulated undistributed earnings on a tax basis was $190,600 (includes a timing difference of $95,578 for dividends payable) tax-exempt income, $213,692 of ordinary income and $5,126,935 long-term capital gains. The accumulated capital gains and net investment income differs from the amount on the Statement of Assets and Liabilities primarily due to timing differences. The United States federal income tax basis of the Series' investments and the net unrealized appreciation as of August 31, 2003 were as follows: TOTAL NET UNREALIZED TAX BASIS APPRECIATION DEPRECIATION APPRECIATION - ------------------ ------------------ ------------------ ------------ $155,005,440 $5,889,319 $3,375,948 $2,513,371 22 Visit our website at www.jennisondryden.com <Page> The difference between book basis and tax basis is primarily attributable to the difference in the treatment of market discount for book and tax purposes. NOTE 6. CAPITAL The Series offers Class A, Class B and Class C shares. Class A shares are sold with a front-end sales charge of up to 3%. Class B shares are sold with a contingent deferred sales charge which declines from 5% to zero depending on the period of time the shares are held. Class C shares are sold with a front-end sales charge of 1% and a contingent deferred sales charge of 1% during the first 18 months. Class B shares will automatically convert to Class A shares on a quarterly basis approximately seven years after purchase. Special exchange privileges are also available for shareholders who qualify to purchase Class A shares at net asset value. The Series has authorized an unlimited number of shares of beneficial interest of each class at $.01 par value per share.

Dryden Municipal Series Fund - Pennsylvania Series 31 <Page> Report of Independent Auditors To the Shareholders and Trustees of Dryden Municipal Series Fund In our opinion, the accompanying statement of assets and liabilities, including the portfolio 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 Dryden Municipal Series Fund (formerly, Prudential Municipal Series Fund), Pennsylvania Series (one of the portfolios constituting Dryden Municipal Series Fund, hereafter referred to as the 'Fund') at August 31, 2003, the results of its operations for the year then ended, the changes in its 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 August 31, 2003 by correspondence with the custodian and broker, provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP New York, New York October 22, 2003 32 Visit our website at www.jennisondryden.com <Page> Federal Income Tax Information (Unaudited) We are required by the Internal Revenue Code to advise you within 60 days of the Series' fiscal year end (August 31, 2003) as to the federal tax status of dividends paid by the Series during such fiscal year. Accordingly, we are advising you that in the fiscal year ended August 31, 2003, dividends paid from net investment income of $0.43 per share for Class A shares, $0.40 per Class B share and $0.37 per Class C share were all federally tax-exempt interest dividends. In addition, the Series paid distributions of $0.0219 per share which represents distributions from 18% long-term capital gains.

The graph compares a $10,000 investment in the Dryden Municipal Series Fund/Pennsylvania Series (Class A shares) with a similar investment in the Lehman Brothers Municipal Bond Index by portraying the initial account values at the beginning of the ten-year period of Class A shares (August 31, 1993) and the account values at the end of the current fiscal year (August 31, 2003) as measured on a quarterly basis. For purposes of the graph, and unless otherwise indicated, it has been assumed that (a) the maximum applicable front-end sales charge was deducted from the initial $10,000 investment in Class A shares; (b) all recurring fees (including management fees) were deducted; and (c) all dividends and distributions were reinvested. The line graph provides information for Class A shares only. As indicated in the tables, performance for Class B and Class C shares will vary due to the differing charges and expenses applicable to each share class (as indicated in the following paragraphs). Without a distribution and service (12b-1) fee waiver of 0.05% for Class A shares, the returns for Class A shares shown in the graph and in the tables would have been lower. The returns on investment in the graph and in the tables do not reflect the deduction of taxes that a shareholder would pay on fund distributions or following the redemption of fund shares. Visit our website at www.jennisondryden.com The Lehman Brothers Municipal Bond Index is an unmanaged index of over 39,000 long-term investment-grade municipal bonds. It gives a broad look at how long-term investment-grade municipal bonds have performed. The Lehman Brothers Municipal Bond Index's total returns include the reinvestment of all dividends, but do not include the effects of sales charges, operating expenses of a mutual fund, or taxes. These returns would be lower if they included the effects of sales charges, operating expenses, or taxes. The securities that comprise the Lehman Brothers Municipal Bond Index may differ substantially from the securities in the Series. The Lehman Brothers Municipal Bond Index is not the only index that may be used to characterize performance of municipal bond funds. Other indexes may portray different comparative performance. Investors cannot invest directly in an index. The Series charges a maximum front-end sales charge of 3% for Class A shares and a 12b-1 fee of up to 0.30% annually. Class A shares may not be subject to a front-end sales charge, but may be subject to a 1% contingent deferred sales charge (CDSC) for the first year. Class B shares are subject to a declining CDSC of 5%, 4%, 3%, 2%, 1%, and 1% respectively for the first six years after purchase and a 12b-1 fee of 0.50% annually. Approximately seven years after purchase, Class B shares will automatically convert to Class A shares on a quarterly basis. Class C shares are subject to a front-end sales charge of 1%, a CDSC of 1% for shares redeemed within 18 months of purchase, and a 12b-1 fee of up to 1% annually. Without waiver of fees and/or expense subsidization, the Series' returns in the tables would have been lower, as indicated in parentheses.
