DEAR SHAREHOLDER,

The year 2003 marked the end of the three-year equity
bear market, with the resurgence of stocks of all sizes
and styles and from a variety of industries. However,
the greatest gains were made by small-cap, rather than
large-cap stocks, and by those whose stock price had
fallen the farthest since the March 2000 market peaks,
particularly technology stocks. In general, mid-cap
stocks performed better than large-caps, yet not as well
as small-caps. Although investment-grade bond
performance was quite subdued, many high yield and
convertible bonds soared. It is no coincidence that both
those bond sectors are heavily influenced by the
fortunes of the stock market.

The turning point for stocks came in mid-March as the
U.S. ended the uncertainty over the impending Iraq War
and the major combat came to a swift completion.
Meanwhile, historically low interest rates and lowered
income taxes provided a double economic stimulus, which
first raised expectations for economic growth and then
led to gains in consumer confidence and rapid expansion.
But, job growth remained sluggish, causing some concerns
over the sustainability of both the economic rebound and
the market's positive performance.

Within this environment, the funds performed as follows:

ALL FIGURES REPRESENT PAST PERFORMANCE AND ARE NOT A GUARANTEE OF FUTURE
RESULTS. Principal value and investment returns will fluctuate and investors'
shares, when redeemed may be worth more or less than their original cost.

Each fund's returns reflect expenses incurred by that fund, but do not reflect
any charges or expenses imposed by the variable annuity or life contract you
own, and do not reflect the deduction of any taxes. Therefore, your actual
returns would have been lower. An investor may not invest directly in the fund.

Index returns are provided for comparison, but an investor cannot invest
directly in an index. Additionally, these returns do not reflect any deduction
for fees or expenses, as indices are unmanaged, and do not incur such expenses.
Index returns also do not reflect any deduction for taxes.

The Merrill Lynch Investment Grade Convertible Bond Index is an index comprised
of convertible bonds rated investment-grade. The Russell Midcap Growth Index
measures the performance of those Russell Midcap companies with higher
price-to-book ratios and higher forecasted growth values (A price-to-book ratio
is the price of a stock compared to the difference between a company's assets
and liabilities). The Russell 2000 Index measures the performance of the 2000
smallest companies in the Russell 3000 Index, which represents approximately 8%
of the total market capitalization of the Russell 3000 Index. The S&P 500 Index
is a market capitalization-weighted index of 500 widely held common stocks. The
Russell 1000 Index measures the performance of the 1000 largest companies in the
Russell 3000 Index, which represents approximately 92% of the total market
capitalization of the Russell 3000 index.

Lipper specialty/miscellaneous variable funds category. Returns were calculated
among the 120 funds for the six-month period and among the 113 funds for the

Please read on for a more detailed look at prevailing economic and market
conditions during the funds' fiscal year and to learn how those conditions and
changes made to the portfolio during this time may have affected fund
performance.

INFORMATION ABOUT YOUR FUND

In recent months several issues in the mutual fund and variable insurance
products industries have come under the scrutiny of federal and state
regulators. Travelers Life & Annuity and some of its affiliates have received
requests for information from various government regulators regarding market
timing, late trading, and other mutual fund and variable product issues in
connection with various investigations. The fund has been informed that
Travelers Life & Annuity and its affiliates are responding to those information
requests and cooperating with the regulators, but are not in a position to
predict the outcome of these requests and investigations.

As always, thank you for your confidence in our stewardship of your assets. We
look forward to helping you continue to meet your financial goals.

Sincerely,

/s/ R. JAY GERKEN

                                MANAGER OVERVIEW

CONVERTIBLE SECURITIES PORTFOLIO

PERFORMANCE UPDATE

During its fiscal year ended December 31, 2003, the fund returned 26.26%. In
comparison, the fund outperformed its benchmark, the Merrill Lynch Investment
Grade Convertible Bond Index(i), which returned 11.51%, but underperformed the
Lipper specialty/miscellaneous variable funds category average, which was 40.40%
for the same period.(1)

The fund's bias towards investment-grade companies held back performance, as non
investment-grade issues experienced the most marked gains over the fund's fiscal
year. The fund benefited from the rise in equity valuations as well as from
significant spread tightening, (the difference between the yields of two bonds
with the same maturities), in the corporate markets. Investors continued to
drive the convertibles market higher as the economic recovery picked up steam
and all U.S. equity benchmarks made significant gains.

It was a landmark year for new convertible bond issuance -- it was the best year
in terms of new issues and the second best year in terms of proceeds after 2001.
The convertible primary market continued to rebound in December, when new
issuance typically slows down. However, there were also a record number of
redemptions in 2003, with a hefty amount of convertible bonds taken out of
circulation.

All three of the style indices advanced in the fourth quarter, led by the equity
alternative securities. As of the end of December, yield alternative securities
(convertibles that trade more like bonds) accounted for just 44% of the
benchmark index, down in the last three quarters as a result of the strong
equity markets. The total return alternative securities, which are classic-style
convertibles gained in the fourth quarter, but not as much as equity-sensitive
convertible securities, which trade more like stocks, did -- reflecting the
strength in the stock market.

WHAT AFFECTED FUND PERFORMANCE?

The fund's top-performing convertible during its fiscal year was FORD MOTOR CO.
The automaker continued to benefit as investors gravitated towards riskier
issues as they expect the improving economy to lift Corporate America's
prospects, causing the convertible to enjoy double-digit gains during the fourth
quarter. Other strong performers during the year were THE GAP, INC., TYCO
INTERNATIONAL LTD. and NEWELL RUBBERMAID INC. The fund's worst performing
convertible during its fiscal year was LINCARE HOLDINGS INC. The convertible was
pressured by Medicare reimbursement reductions introduced by the U.S. Congress,
which investors fear will hurt the company's bottom line significantly.

Thank you for your investment in the Convertible Securities Portfolio. We
appreciate that you have entrusted us to manage your money and value our
relationship with you.

Sincerely,

                                MANAGER OVERVIEW

MFS MID CAP GROWTH PORTFOLIO

PERFORMANCE UPDATE

During its fiscal year ended December 31, 2003, the fund returned 37.05%. In
comparison, the fund underperformed both of its benchmarks, the Russell Midcap
Growth Index,(i) which returned 42.71% as well as the Russell 2000 Index(ii),
which returned 47.25% for the same period. However, the fund outperformed its
Lipper mid-cap growth variable funds category average, which was 36.34% for the
same period.(1)

MARKET ENVIRONMENT

In the early months of 2003, investors were battered by economic and
geopolitical uncertainty. By year-end, however, they were upbeat as 2003 was the
first positive year for most global markets in four years. The turnaround in
global stock markets began in March and April, when it became apparent that the
U.S.- and British-led coalition was on the verge of military success in Iraq.
Increasingly positive economic numbers, particularly corporate earnings,
prompted an ensuing market rally. Additionally, as the year progressed, investor
focus on negative factors such as the Iraq situation, a short-lived SARS
epidemic, and corporate misdeeds decreased.

In the equity markets, the big surprise of 2003 was investors' appetite for
risk. After a brutal three-year market decline, many observers believed
investors would avoid risky investments. Instead, the markets experienced an
equity rally led by relatively low-quality, higher-risk stocks -- stocks of
companies with substantial debt on their balance sheets, low profit margins,
and/or second- and third-tier competitive positioning. Investors seemed to favor
the stocks that had fallen the hardest, rather than bidding up industry leaders
that had weathered the global downturn relatively well.

PERFORMANCE CONTRIBUTORS

Wireless tower rental companies CROWN CASTLE INTERNATIONAL CORP. and AMERICAN
TOWER CORPORATION, in the utilities and communication sector, were the fund's
best performing stocks. Cash flow growth and improving fundamentals drove these
stocks higher. In addition, debt refinancing improved overall balance sheets for
these companies.

In the leisure sector, Internet travel firm EXPEDIA, INC. benefited from market
share gains in the online travel business and posted solid results. Satellite TV
operator ECHOSTAR COMMUNICATIONS CORPORATION posted strong gains as the company
expanded its subscriber base and generated strong growth in free cash flows.
Shares of NTL INCORPORATED, the largest broadband and cable operator in the U.K.
and Ireland, soared after the company emerged from bankruptcy and continued to
strengthen its balance sheet and drive cash flow growth.

Contributors in technology included data storage software supplier VERITAS
SOFTWARE CORPORATION, which benefited from a recovery in technology spending for
storage software. Semiconductor company ANALOG DEVICES, INC. contributed to
performance due to an upswing in semiconductor demand and market share gains for
its well-positioned products.

The fund's investments in healthcare also contributed to performance.
Biotechnology equipment vendor INVITROGEN CORPORATION, which sells life science
tools used in research and drug manufacturing, benefited from an industry
recovery and improved product offerings and efficiency gains under a new CEO.
GENENTECH, INC.'S stock soared after receiving FDA approval for Avastin, an
innovative new cancer drug. We sold Genentech during the period and took some
profits. GUIDANT CORPORATION posted strong gains after an earlier sell-off,
based on the company's leading position in cardiac rhythm management and future
possibilities in drug-coated stents.

(1) Lipper, Inc. is a major independent mutual-fund tracking organization.
    Returns are based on the 12-month period ended December 31, 2003, calculated
    among the 113 funds in the Lipper mid-cap growth variable funds category
    including the reinvestment of dividends and capital gains, if any.

DETRACTORS FROM PERFORMANCE

Despite solid gains from select stocks, the returns from the fund's overall
technology position trailed the benchmark's. NETWORK ASSOCIATES, INC. lagged as
sales of the company's industry leading anti-spam and anti-virus software were
slow to accelerate and were unable to meet or exceed our expectations. Software
developer PEOPLESOFT, INC. detracted from performance as demand for the
company's release of its product upgrade was not as robust as anticipated. We
sold Peoplesoft prior to the end of the period.

Media holding WESTWOOD ONE, INC. detracted from performance as the pickup in
advertising, which is tied to the economic recovery, proved slower than
expected. Weight loss services company WEIGHT WATCHERS INTERNATIONAL, INC.'S
stock price declined as fundamentals weakened in the face of competing diet
programs. We sold Weight Watchers during the period as our fundamental thesis
was not playing out as anticipated. Adult education provider CAREER EDUCATION
CORPORATION'S stock retreated late in the year amid allegations that employees
falsified accreditation documents, charges which management vigorously denies.
The fund was also negatively impacted by not owning two stocks in the Russell
Midcap Growth Index that performed well: AMAZON.COM, INC., which we avoided
based on valuation; and NEXTEL COMMUNICATIONS, INC., which the fund did not own
based on concerns about the competitive dynamic among wireless carriers.

The portfolio's cash position also detracted from relative performance. As with
nearly all annuity subaccounts, the fund holds some cash to buy new holdings and
to cover investor exchanges or redemptions. In a period when equity markets rose
sharply, the fund's cash holdings hurt performance against the Russell Midcap
Growth Index, which has no cash position.

that you have entrusted us to manage your money and value our relationship with
you.

                                MANAGER OVERVIEW

MERRILL LYNCH LARGE CAP CORE PORTFOLIO (FORMERLY, MFS RESEARCH PORTFOLIO)

PERFORMANCE UPDATE

During its fiscal year ended December 31, 2003, the fund returned 21.16%. In
comparison, the fund underperformed its benchmarks, the unmanaged S&P 500
Index(i) and Russell 1000 Index(ii), which returned 28.67% and 29.89%,
respectively, for the same period. The fund underperformed its Lipper large-cap
core funds category average, which was 26.42% for the same period.(1)

We assumed management responsibility for the fund on November 17, 2003. We have
invested the assets in a manner designed to outperform other large cap core
portfolios using securities found in the Russell 1000 Index. Our investment
process attempts to add value through both security selection and portfolio
construction. We use quantitative selection criteria including earnings
momentum, earnings surprise and valuation. These criteria are input into a
proprietary quantitative model and are subject to selective fundamental
overrides. Portfolio construction consists of an optimization process with risk
management controlling style, capitalization, sector and individual security
bets.

The fund recorded mixed performance from November 17, 2003 through year-end
December 31, 2003, as we restructured the portfolio to bring it in line with our
current outlook (we turned over about half of the positions). Performance
benefited from favorable stock selection within the financials and consumer
staples sectors. On the flip side, underperformance resulted from poor stock
selection within the information technology and consumer discretionary sectors,
in addition to an underweight in the energy sector. At the individual stock
level, the largest outperformers were E*TRADE FINANCIAL CORP., PULTE HOMES,
INC., ACE LIMITED, GETTY IMAGES, INC. and GEORGIA PACIFIC CORPORATION. In
addition, the fund's underweight position in WAL-MART STORES, INC. had a
positive impact on performance. These were offset by underperformance in SANDISK
CORPORATION, SEARS, ROEBUCK & CO., JOHNSON & JOHNSON INC, and AGERE SYSTEMS INC.

As mentioned, we restructured the portfolio to position it in a more
pro-cyclical manner. These actions were based on our continuing belief that
economic momentum would be positive for the balance of this year and into 2004.
As a result, we added most significantly to information technology and consumer
discretionary while reducing exposure to consumer staples, energy, and health
care. Our largest purchases were GENERAL ELECTRIC COMPANY, J.P. MORGAN CHASE &
CO., PFIZER INC., and TEXAS INSTRUMENTS INC., and our largest sales were JOHNSON
& JOHNSON INC, TARGET CORPORATION, MICROSOFT CORPORATION, VERIZON COMMUNICATIONS
INC., and KOHL'S CORPORATION.

The fund is now overweighted in cyclical areas of the marketplace including
consumer discretionary and information technology and underweighted in
financials and consumer staples. We are attempting, through careful stock
selection, to be positioned in companies with positive earnings momentum,
earnings surprise, and valuation characteristics.

Thank you for your investment in the Merrill Lynch Large Cap Core Portfolio. We
appreciate that you have entrusted us to manage your money and value our
relationship with you.

Sincerely,

/s/ ROBERT C. DOLL, JR.

performance rather than the S&P 500 Index.

 BOND RATINGS (UNAUDITED)

The definitions of the applicable rating symbols are set forth below:

Standard & Poor's Ratings Service ("Standard & Poor's") -- Ratings from "AA" to
"CCC" may be modified by the addition of a plus (+) or minus (-) sign to show
relative standings within the major rating categories.

<Table>
                  
AAA                --   Bonds rated "AAA" have the highest rating assigned by
                        Standard & Poor's. Capacity to pay interest and repay
                        principal is extremely strong.
AA                 --   Bonds rated "AA" have a very strong capacity to pay interest
                        and repay principal and differ from the highest rated issue
                        only in a small degree.
A                  --   Bonds rated "A" have a strong capacity to pay interest and
                        repay principal although they are somewhat more susceptible
                        to the adverse effects of changes in circumstances and
                        economic conditions than bonds in higher rated categories.
BBB                --   Bonds rated "BBB" are regarded as having an adequate
                        capacity to pay interest and repay principal. Whereas they
                        normally exhibit adequate protection parameters, adverse
                        economic conditions or changing circumstances are more
                        likely to lead to a weakened capacity to pay interest and
                        repay principal for bonds in this category than in higher
                        rated categories.
BB, B, CCC and CC  --   Bonds rated "BB", "B", "CCC" and "CC" are regarded, on
                        balance, as predominantly speculative with respect to the
                        issuer's capacity to pay interest and repay principal in
                        accordance with the terms of the obligation. "BB" indicates
                        the lowest degree of speculation and "CC" the highest degree
                        of speculation. While such bonds will likely have some
                        quality and protective characteristics, these are outweighed
                        by large uncertainties or major risk exposures to adverse
                        conditions.
</Table>

Moody's Investors Service ("Moody's") -- Numerical modifiers 1, 2, and 3 may be
applied to each generic rating from "Aa" to "Caa", where 1 is the highest and 3
the lowest ranking within its generic category.
<Table>
                  
Aaa                --   Bonds rated "Aaa" are judged to be of the best quality. They
                        carry the smallest degree of investment risk and are
                        generally referred to as "gilt edge." Interest payments are
                        protected by a large or by an exceptionally stable margin
                        and principal is secure. While the various protective
                        elements are likely to change, such changes as can be
                        visualized are most unlikely to impair the fundamentally
                        strong position of such an issue.
Aa                 --   Bonds rated "Aa" are judged to be of high quality by all
                        standards. Together with the "Aaa" group they comprise what
                        are generally known as high grade bonds. They are rated
                        lower than the best bonds because margins of protection may
                        not be as large in "Aaa" securities or fluctuation of
                        protective elements may be of greater amplitude or there may
                        be other elements present which make the long-term risks
                        appear somewhat larger than in "Aaa" securities.
A                  --   Bonds rated "A" possess many favorable investment attributes
                        and are to be considered as upper medium grade obligations.
                        Factors giving security to principal and interest are
                        considered adequate but elements may be present which
                        suggest a susceptibility to impairment some time in the
                        future.
Baa                --   Bonds rated "Baa" are considered as medium grade
                        obligations; i.e., they are neither highly protected nor
                        poorly secured. Interest payments and principal security
                        appear adequate for the present but certain protective
                        elements may be lacking or may be characteristically
                        unreliable over any great length of time. Such bonds lack
                        outstanding investment characteristics and in fact have
                        speculative characteristics as well.
Ba                 --   Bonds rated "Ba" are judged to have speculative elements;
                        their future cannot be considered as well assured. Often the
                        protection of interest and principal payments may be very
                        moderate and thereby not well safeguarded during both good
                        and bad times over the future. Uncertainty of position
                        characterizes bonds in this class.
B                  --   Bonds rated "B" generally lack characteristics of desirable
                        investments. Assurance of interest and principal payments or
                        of maintenance of other terms of the contract over any long
                        period of time may be small.
Caa                --   Bonds rated "Caa" are of poor standing. Such issues may be
                        in default, or there may be present elements of danger with
                        respect to principal or interest.
Ca                 --   Bonds rated "Ca" represent obligations which are speculative
                        in a high degree. Such issues are often in default or have
                        other marked shortcomings.
C                  --   Bonds rated "C" are the lowest rated class of bonds, and
                        issues so rated can be regarded as having extremely poor
                        prospects of ever attaining any real investment standing.

NR                 --   Indicates that the bond is not rated by Standard & Poor's or
                        Moody's.

 NOTES TO FINANCIAL STATEMENTS

     1.  SIGNIFICANT ACCOUNTING POLICIES

     The Convertible Securities, MFS Mid Cap Growth and Merrill Lynch Large Cap
Core (formerly known as MFS Research) Portfolios ("Fund(s)") are separate
investment funds of The Travelers Series Trust ("Trust"). The Convertible
Securities Portfolio and the Merrill Lynch Large Cap Core Portfolio are separate
diversified investment funds of the Trust. The MFS Mid Cap Growth Portfolio is a
separate non-diversified investment fund of the Trust. The Trust is a
Massachusetts business trust registered under the Investment Company Act of
1940, as amended, as an open-end management investment company and consists of
these Funds and thirteen other separate investment funds: Travelers Quality
Bond, Lazard International Stock, MFS Emerging Growth, Federated High Yield,
Federated Stock, Disciplined Mid Cap Stock, U.S. Government Securities, Social
Awareness Stock, Pioneer Fund, formerly known as Utilities, Large Cap, Equity
Income, Zero Coupon Bond Fund (Series 2005) and MFS Value Portfolios. The
financial statements and financial highlights for the other funds are presented
in separate shareholder reports. The Funds and the other investment funds of the
Trust are offered exclusively for use with certain variable annuity and variable
life insurance contracts offered through the separate accounts of various
affiliated life insurance companies.

     The significant accounting policies consistently followed by the Funds are:
(a) security transactions are accounted for on trade date; (b) securities traded
on national securities markets are valued at the closing price on such markets
or, if there were no sales during the day, at the mean between the closing bid
and asked prices; securities primarily traded on foreign exchanges are generally
valued at the closing values of such securities on their respective exchanges,
except that when a significant occurrence exists subsequent to the time a value
was so established and it is likely to have significantly changed the value,
then the fair value of those securities will be determined by consideration of
other factors by or under the direction of the Board of Trustees; securities
listed on the NASDAQ National Market System for which market quotations are
available are valued at the official closing price or, if there is no official
closing price on that day, at the last sale price; securities traded in the
over-the-counter market are valued at prices based on market quotations for
securities of similar type; U.S. government agencies and obligations are valued
at the mean between the last reported bid and asked prices; (c) securities
maturing within 60 days are valued at cost plus accreted discount or minus
amortized premium, which approximates value; (d) securities, other than U.S.
government agencies, that have a maturity of 60 days or more are valued at
prices based on market quotations for securities of similar type, yield and
maturity; (e) interest income, adjusted for amortization of premium and
accretion of discount, is recorded on an accrual basis and dividend income is
recorded on the ex-dividend date; foreign dividends are recorded on the
ex-dividend date or as soon as practical after the Fund determines the existence
of a dividend declaration after exercising reasonable due diligence; (f) gains
or losses on the sale of securities are calculated by using the specific
identification method; (g) dividends and distributions to shareholders are
recorded on the ex-dividend date; the Funds distribute dividends and capital
gains, if any, at least annually; (h) the accounting records of the Funds are
maintained in U.S. dollars. All assets and liabilities denominated in foreign
currencies are translated into U.S. dollars on the date of valuation. Purchases
and sales of securities, income and expenses are translated at the rate of
exchange quoted on the respective date that such transactions are recorded.
Differences between income or expense amounts recorded and collected or paid are
adjusted when reported by the custodian; (i) the character of income and gains
to be distributed is determined in accordance with income tax regulations which
may differ from accounting principles generally accepted in the United States of
America. At December 31, 2003, reclassifications were made to the capital
accounts of the Convertible Securities and MFS Mid Cap Growth Portfolios to
reflect permanent book/tax differences and income and gains available for
distributions under income tax regulations. Accordingly, a portion of
accumulated net investment loss amounting to $783,682 was reclassified to
paid-in capital for the MFS Mid Cap Growth Portfolio. Net investment income, net
realized gains and net assets were not affected by this adjustment; (j) the
Funds intend to comply with the applicable provisions of the Internal Revenue
Code of 1986, as amended, pertaining to regulated investment companies and to
make distributions of taxable income sufficient to relieve it from substantially
all Federal income and excise taxes; and (k) estimates and assumptions are
required to be made regarding assets, liabilities and changes in net assets
resulting from operations when financial statements are prepared. Changes in the
economic environment, financial markets and any other parameters used in
determining these estimates could cause actual results to differ.

     In addition, the MFS Mid Cap Growth and Merrill Lynch Large Cap Core
Portfolios may enter into forward exchange contracts in order to hedge against
foreign currency risk. These contracts are marked to market daily, by
recognizing the difference between the contract exchange rate and the current
forward rate as an unrealized gain or loss. Realized gains or losses are
recognized when the contracts are settled.

                                                                              31

     2.  INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS

     Travelers Asset Management International Company LLC ("TAMIC"), an indirect
wholly-owned subsidiary of Citigroup Inc. ("Citigroup"), acts as investment
adviser to the Convertible Securities ("CS"), MFS Mid Cap Growth ("MMCG") and
Merrill Lynch Large Cap Core ("MLLCC") Portfolios. CS, MMCG and MLLCC each pay
TAMIC an investment advisory fee calculated at annual rates of 0.60%, 0.80% and
0.80%, respectively. These fees are calculated daily and paid monthly.

     TAMIC has entered into a sub-advisory agreement with Massachusetts
Financial Services ("MFS"). Pursuant to the sub-advisory agreement, MFS is
responsible for the day-to-day fund operations and investment decisions for
MMCG. As a result, TAMIC pays MFS a sub-advisory fee at an annual rate of 0.375%
of the average daily net assets of MMCG.

     For the period from January 1, 2003 through November 16, 2003, TAMIC had a
sub-advisory agreement with MFS. Pursuant to the sub-advisory agreement, MFS was
responsible for the day-to-day fund operations and investment decisions for
MLLCC and was compensated by TAMIC for such services at an annual rate of 0.375%
of the average daily net assets of MLLCC.

     Effective November 17, 2003, the sub-advisory agreement with MFS on behalf
of MLLCC was terminated and TAMIC entered into a new sub-advisory agreement with
Merrill Lynch Investment Managers, L.P. ("MLIM"), which was approved by the
shareholders on November 14, 2003. Pursuant to the new sub-advisory agreement,
MLIM is responsible for the day-to-day fund operations and investment decisions
and is compensated by TAMIC for such services at an annual rate of 0.375% of the
average daily net assets of MLLCC.

     The Travelers Insurance Company ("TIC"), another indirect wholly-owned
subsidiary of Citigroup, acts as administrator to the Funds. The Funds pay TIC
an administration fee calculated at an annual rate of 0.06% of the average daily
net assets of each respective Fund. This fee is calculated daily and paid
monthly. TIC has entered into a sub-administrative service agreement with Smith
Barney Fund Management LLC ("SBFM"), another indirect wholly-owned subsidiary of
Citigroup. TIC pays SBFM, as sub-administrator, a fee calculated at an annual
rate of 0.02% of the average daily net assets of each Fund, plus $30,000 per
Fund, subject to a maximum of 0.06% of each Fund's average daily net assets.

     Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as
the Funds' transfer agent. CTB receives account fees and asset-based fees that
vary according to the size and type of account. For the year ended December 31,
2003, each Fund paid transfer agent fees of $5,000 to CTB.

     For the year ended December 31, 2003, Citigroup Global Markets Inc. ("CGM")
(formerly known as Salomon Smith Barney Inc.), another indirect wholly-owned
subsidiary of Citigroup, received brokerage commissions of $245 from MLLCC.

     One Trustee and all officers of the Trust are employees of Citigroup or its
subsidiaries.

     3.  INVESTMENTS

     4.  REPURCHASE AGREEMENTS

     The Funds purchase (and the custodian takes possession of) U.S. government
securities from securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day),
at an agreed-upon higher repurchase price. The Funds require continual
maintenance of the market value (plus accrued interest) of the collateral in
amounts at least equal to the repurchase price.

     At December 31, 2003, MMCG did not have any repurchase agreements
outstanding.

     5.  FORWARD FOREIGN CURRENCY CONTRACTS

     MMCG and MLLCC may enter into forward foreign currency contracts. A forward
foreign currency contract is an agreement between two parties to buy and sell a
currency at a set price on a future date. The contract is marked-to-market daily
and the change in value is recorded by the Fund as an unrealized gain or loss.
When a forward foreign currency contract is extinguished, through either
delivery or offset by entering into another forward foreign currency contract,
the Fund records a realized gain or loss equal to the difference between the
value of the contract at the time it was opened and the value of the contract at
the time it was extinguished or offset. The Fund bears the market risk that
arises from changes in foreign currency exchange rates and the credit risk
should a counterparty be unable to meet the terms of such contracts.

     At December 31, 2003, MMCG and MLLCC did not have any open forward foreign
currency contracts.

     6.  SHARES OF BENEFICIAL INTEREST

     The Declaration of Trust authorizes the issuance of an unlimited number of
shares of beneficial interest without par value. Transactions in shares of each
Fund were as follows:

     7.  CAPITAL LOSS CARRYFORWARDS

     At December 31, 2003, CS, MMCG and MLLCC had, for Federal income tax
purposes, approximately $2,127,000, $248,594,000 and $80,178,000, respectively,
of capital loss carryforward available to offset future capital gains. To the
extent that these carryforward losses can be used to offset realized capital
gains, it is probable that such gains will not be distributed. The amounts and
expiration of the carryforwards are indicated below. Expiration occurs on
December 31 of the year indicated:

     At December 31, 2003, CS, MMCG and MLLCC, the differences between book

of premiums.

     9.  ADDITIONAL INFORMATION

     The Funds have received the following information from Citigroup Asset
Management ("CAM"), the Citigroup business unit which includes the Funds'
Investment Manager, and other investment advisory companies, all of which are
indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry,
through an affiliate, into the transfer agent business in the period 1997-1999.
As CAM currently understands the facts, at the time CAM decided to enter the
transfer agent business, CAM sub-contracted for a period of five years certain
of the transfer agency services to a third party and also concluded a revenue
guarantee agreement with this sub-contractor providing that the sub-contractor
would guarantee certain benefits to CAM or its affiliates (the "Revenue
Guarantee Agreement"). In connection with the subsequent purchase of the
sub-contractor's business by an affiliate of the current sub-transfer agent
(PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee
Agreement was amended eliminating those benefits in exchange for arrangements
that included a one-time payment from the sub-contractor.

 34


- --------------------------------------------------------------------------------
 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     The Boards of CAM-managed funds (the "Boards") were not informed of the
Revenue Guarantee Agreement with the sub-contractor at the time the Boards
considered and approved the transfer agent arrangements. Nor were the Boards
informed of the subsequent amendment to the Revenue Guarantee Agreement when
that occurred.

     CAM has begun to take corrective actions. CAM will pay to the applicable
funds approximately $17 million (plus interest) that CAM and its affiliates
received from the Revenue Guarantee Agreement and its amendment. CAM also plans
an independent review to verify that the transfer agency fees charged by CAM
were fairly priced as compared to competitive alternatives. CAM is instituting
new procedures and making changes designed to ensure no similar arrangements are
entered into in the future.

     CAM has briefed the SEC, the New York State Attorney General and other
regulators with respect to this matter, as well as the U.S. Attorney who is
investigating the matter. CAM is cooperating with governmental authorities on
this matter, the ultimate outcome of which is not yet determinable.

                                                                              35

(1) Per share amounts have been calculated using the monthly average shares
    method.

(2) The Travelers Insurance Company has agreed to reimburse the Fund for
    expenses in the amounts of $6,833, $18,530 and $32,000 for the years ended
    December 31, 2002, December 31, 2000 and December 31, 1999, respectively. If
    such expenses were not reimbursed, the per share decreases to net investment
    income and the actual expense ratios would have been as follows:

</Table>

(3) Effective January 1, 2001, the Fund adopted a change in the accounting
    method that requires the Fund to amortize premiums and accrete all
    discounts. Without the adoption of this change, for the year ended December
    31, 2001, the ratio of net investment income to average net assets would
    have been 3.99%. Per share information, ratios and supplemental data for the
    periods prior to January 1, 2001 have not been restated to reflect this
    change in presentation. In addition, the impact of this change to net
    investment income and net realized and unrealized loss was less than $0.01
    per share.

(4) Performance figures may reflect fee waivers and/or expense reimbursements.
    Past performance is no guarantee of future results. In the absence of fee
    waivers and/or expense reimbursements, the total return would be reduced.
    Total returns do not reflect expenses associated with your variable contract
    such as administrative fees, account charges and surrender charges which, if
    reflected, would reduce the total returns for all periods shown.

(5) As a result of a voluntary expense limitation, the ratio of expenses to
    average net assets will not exceed 0.80%.

 *  Amount represents less than $0.01 per share.

 INDEPENDENT AUDITORS' REPORT

THE SHAREHOLDERS AND BOARD OF TRUSTEES OF
THE TRAVELERS SERIES TRUST:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of the Convertible Securities Portfolio, MFS Mid
Cap Growth Portfolio and Merrill Lynch Large Cap Core Portfolio (formerly known
as MFS Research Portfolio) ("Funds") of The Travelers Series Trust ("Trust"), as
of December 31, 2003, and the related statements of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended and financial highlights for each of the years in the
five-year period then ended. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of December 31, 2003, by correspondence with the custodian
and broker. As to securities purchased or sold but not yet received or
delivered, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Convertible Securities Portfolio, MFS Mid Cap Growth Portfolio, and Merrill
Lynch Large Cap Core Portfolio of the Trust as of December 31, 2003, and the
results of their operations for the year then ended and the changes in their net
assets for each of the years in the two-year period then ended and the financial
highlights for each of the years in the five-year period then ended in
conformity with accounting principles generally accepted in the United States of
America.

                                                                    /s/ KPMG LLP

    (d)  All Other Fees for The Travelers Series Trust of $0 and $0 for the

    (e)  (1) Audit Committee's pre-approval policies and procedures described
         in paragraph (c) (7) of Rule 2-01 of Regulation S-X.

         The Audit Committee ("Committee") has adopted policies and procedures
         to, among other purposes, approve all audit and non-audit services
         provided to the Registrant and certain other persons by the
         Registrant's independent auditors.

         The Committee shall not approve non-audit services that the Committee
         believes may taint the independence of the auditors. As of the date of
         the approval of this Audit Committee Charter, permissible non-audit
         services include any professional services (including tax services),
         that are not prohibited services as described below, provided to the
         Fund by the independent auditors, other than those provided to the Fund
         in connection with an audit or a review of the financial statements of
         the Fund. Permissible non-audit services may not include: (i)
         bookkeeping or other services related to the accounting records or
         financial statements of the Fund; (ii) financial information systems
         design and implementation; (iii) appraisal or valuation services,
         fairness opinions or contribution-in-kind reports; (iv) actuarial
         services; (v) internal audit outsourcing services; (vi) management
         functions or human resources; (vii) broker or dealer, investment
         adviser or investment banking services; (viii) legal services and
         expert services unrelated to the audit; and (ix) any other service the
         Public Company Accounting Oversight Board determines, by regulation, is
         impermissible.

         The policies and procedures require the Committee to approve (a) all
         audit and permissible non-audit services to be provided to the
         Registrant and (b) all permissible non-audit services to be provided by
         the Fund's independent auditors to the Adviser and any Covered Service
         Providers if the engagement relates directly to the operations and
         financial reporting of the Registrant. In carrying out this
         responsibility, the Committee shall seek periodically from the Adviser
         and from the independent auditors a list of audit and permissible
         non-audit services that can be expected to be rendered to the
         Registrant, the Adviser or any Covered Service Providers by the
         Registrant's independent auditors, and an estimate of the fees sought
         to be paid in connection with such services. The Committee may delegate
         its responsibility to approve any such audit and permissible non-audit
         services to a sub-committee consisting of the Chairperson of the
         Committee (the "Chairperson") and at least one other member of the
         Committee, as the Chairperson, from time to time, may determine and
         appoint, and such sub-committee shall report to the Committee, at its
         next meeting after the sub-committee's meeting, its decision(s). From
         year to year, and at such other times as the Committee deems
         appropriate, the Committee shall report to the Board whether this
         system of approval has been effective and efficient or whether this
         Charter should be amended to allow for pre-approval pursuant to such
         policies and procedures as the Committee shall approve, including the
         delegation of some or all of the Committee's per-approval
         responsibilities to other persons (other than the Adviser or the Fund's
         officers).

         Pre-approval by the Committee of any permissible non-audit services is
         not required so long as: (i) the aggregate amount of all such
         permissible non-audit services provided to the Fund, the Adviser and
         any service providers controlling, controlled by or under common
         control with the Adviser that provide ongoing services to the Fund
         ("Covered Service Providers") constitutes not more than 5% of the total
         amount of revenues paid to the independent auditors during the fiscal
         year in which the permissible non-audit services are provided by (a)
         the Fund, (b) the Adviser and (c) any entity controlling, controlled by
         or under common control with the Adviser that provides ongoing services
         to the Fund during the fiscal year in which the services are provided
         that would have to be approved by the Committee; (ii) the permissible
         non-audit services were not recognized by the Fund at the time of the
         engagement to be non-audit services; and (iii) such services are
         promptly brought to the attention of the Committee and approved by the
         Committee (or its delegate(s)) prior to the completion of the audit.

    (h)  Yes. Travelers Series Trust's Audit Committee has considered whether
         the provision of non-audit services that were rendered to Service
         Affiliates which were not pre-approved (not requiring pre-approval) is
         compatible with maintaining the Accountant's independent. All services
         provided by the Accountant to the Travelers Series Trust or to Service
         Affiliates which were required to be pre-approved were pre-approved as
         required.

         that occurred during the registrant's last fiscal half-year (the
         registrant's second fiscal half-year in the case of an annual report)
         that have materially affected, or are likely to materially affect the
         registrant's internal control over financial reporting.
