PIONEER MID CAP VALUE VCT PORTFOLIO             PIONEER VARIABLE CONTRACTS TRUST

PORTFOLIO MANAGEMENT DISCUSSION 6/30/03

The war in Iraq was the most significant factor influencing equity prices during
the first six months of 2003. Equities, including mid-cap value stocks, began to
rally in early March in reaction to optimistic reports about the war's progress.
The rally continued through the end of the period on June 30, 2003 as investors
became more optimistic that the economy would finally emerge from its prolonged
slump. In the following interview, Rod Wright discusses the market environment
and portfolio strategies for the six months ended June 30, 2003. Mr. Wright is
responsible for the day-to-day portfolio supervision of Pioneer Mid Cap Value
VCT Portfolio.

Q: HOW DID THE PORTFOLIO PERFORM?

A: The Portfolio outperformed the overall stock market and finished slightly
   ahead of the benchmark for the mid-cap value universe. For the six-month
   period ended June 30, 2003, the Portfolio's Class II shares had a total
   return of 13.00% at net asset value. During the same period, the Standard &
   Poor's 500 Index, reflecting the performance of large company stocks,
   returned 11.75%, while the Russell Midcap Value Index had a return of 13.11%.

Q: WHAT WAS THE INVESTMENT ENVIRONMENT LIKE DURING THE SIX MONTHS?

A: Virtually all stocks declined during the first weeks of the year, amidst the
   growing apprehension about the looming war with Iraq. In addition to war
   worries, investors were concerned about the weak economy and the continuing
   allegations of corporate fraud and corruption. However, the negative
   sentiment changed abruptly in March as it became evident that the U.S. and
   its allies would gain a quick victory in the major combat in Iraq. Mounting
   optimism also was fueled by passage of a large federal tax cut and by the
   Federal Reserve Board's continuing policy to lower short-term interest rates
   to stimulate the economy. From March 11 through the end of the six-month
   period, stock prices rose steadily on this wave of new optimism, despite the
   lack of clear evidence that economic growth was beginning to increase.

Q: WHAT WERE YOUR PRINCIPAL STRATEGIES DURING THE SIX MONTHS?

A: In general, we stuck to our long-term discipline, emphasizing investments in
   reasonably valued stocks. When specific holdings rise sharply and become more
   expensive, we typically sell some or all of the Portfolio's position to take
   profits and reduce risk. This is in keeping with our goal of consistent
   performance with less risk than competitor portfolios. At the start of the
   year, we overweighted technology stocks. However, as that industry surged
   when the stock market rallied, we reduced our tech position, becoming more
   defensive by adding to our health care, energy and materials holdings.

Q: WHAT INVESTMENTS HAD THE GREATEST POSITIVE INFLUENCE ON PERFORMANCE?

A: Amdocs, a transaction processing company specializing in the operation of
   billing systems for telecommunications companies, was the single largest
   contributor to performance during the six months, gaining 151% during the
   period. However, we gradually reduced our exposure to the company as its
   stock price rose, selling about three-quarters of our position. Other
   technology-related holdings that showed strong gains included Mentor
   Graphics, which produces automated, electronic design software for the
   semiconductor industry, and Symbol Technologies, which develops and
   manufactures scanners and mobile computing devices that help track
   inventories and deliveries. Mentor rose 96% during the six months, while
   Symbol Technologies appreciated 66%.

   IVAX and Mylan Laboratories, two specialty pharmaceutical and generic drug
   manufacturers, both turned in very strong performance based on prospects for
   products in development as well as the improving outlook for generic drugs.

   Other positive contributors included retailer Sears, which rose by 37% since
   we first invested last December, and mining company Freeport-McMoRan.
   Freeport, which owns the largest and lowest-cost mine in the world, benefited
   from the rising price of gold.

Q: WHAT WERE YOUR MAJOR DISAPPOINTMENTS?

A: The biggest detractor from performance was our underweighting of utility
   stocks. As the stock market rallied, some lower-quality utilities posted huge
   gains. In addition, dividend-paying utilities became increasingly attractive
   as interest rates continued to decline.

   Among our holdings, Triad Hospitals, a hospital management company,
   disappointed us during the period, through no fault of its own. It declined
   because of the well-publicized problems of HCA, a major hospital company, and
   because of concerns that hospital usage might be declining. Declining
   fundamentals and intense competition among discount retailers undermined the
   stock value of BJ's Wholesale Club.

Q: WHAT IS YOUR INVESTMENT OUTLOOK?

A: We are concerned about the short term, believing that it is possible the
   market may give back some of its recent gains. We remain defensively
   positioned and are very conscious of valuations in our stock decisions.
   However, we are much more optimistic about the longer term and believe that
   after clear evidence emerges about an economic rebound, the stock market
   could enter a sustained period of good performance. In general, corporations
   have improved their balance sheets and are well positioned to benefit from
   low interest rates and an economic recovery.

THE PRECEDING INFORMATION IS THE OPINION OF FUND MANAGEMENT. PAST PERFORMANCE IS
NO GUARANTEE OF FUTURE RESULTS, AND THERE IS NO GUARANTEE THAT MARKET FORECASTS
DISCUSSED WILL BE REALIZED.

[SIDENOTE]

Mid-capitalization stocks, while offering the potential for higher returns, may
be subject to greater short-term price fluctuations than securities of larger
companies.

The Portfolio's investment adviser, Pioneer Investment Management, Inc., reduced
its management fee and certain other expenses; otherwise, returns would have
been lower.

PIONEER MID CAP VALUE VCT PORTFOLIO

NOTES TO FINANCIAL STATEMENTS 6/30/03 (UNAUDITED)

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

registered under the Investment Company Act of 1940 as an open-end management
investment company. The Trust consists of sixteen separate portfolios
(collectively, the Portfolios, individually the Portfolio) as follows:

PORTFOLIOS:
  Pioneer Emerging Markets VCT Portfolio (Emerging Markets Portfolio)
  Pioneer Europe VCT Portfolio (Europe Portfolio)
  Pioneer International Value VCT Portfolio (International Value Portfolio)

Portfolio shares may be purchased by insurance companies for the purpose of
funding variable annuity or variable life insurance contracts, and may also be
purchased by qualified pension and retirement plans.

The investment objective of Mid Cap Value Portfolio is to seek capital
appreciation.

The Trust's financial statements have been prepared in conformity with
accounting principles generally accepted in the United States that require the
management of the Trust to, among other things, make estimates and assumptions
that affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of revenues and expenses during the reporting periods.
Actual results could differ from those estimates. The following is a summary of
significant accounting policies consistently followed by the Trust, which are in
conformity with those generally accepted in the investment company industry:

A. SECURITY VALUATION
   Security transactions are recorded as of trade date. Net asset values for the
   portfolios are computed once daily, on each day the New York Stock Exchange
   is open, as of the close of regular trading on the Exchange. In computing the
   net asset values, securities are valued at the last sale price on the
   principal exchange where they are traded. Securities that have not traded on
   the date of valuation, or securities for which sale prices are not generally
   reported, are valued at the mean between the last bid and asked prices.
   Trading in foreign equity securities is substantially completed each day at
   various times prior to the close of the New York Stock Exchange. The value of
   such securities used in computing the net asset value of the Portfolio's
   shares, based on the last sale price on the principal exchange where they
   traded, are determined as of such times.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Portfolio is informed of the ex-dividend data in
   the exercise of reasonable diligence. Interest income, including interest on
   income bearing cash accounts, is recorded on the accrual basis, net of
   unrecoverable foreign taxes withheld at the applicable country rates. All
   discounts/premiums are accreted/amortized for financial reporting purposes.

   Gains and losses from sales on investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes.

B. FUTURES CONTRACTS
   The Portfolios may enter into futures transactions to hedge against changes
   in interest rates, securities prices, and currency rates or to seek to
   increase total return. Upon entering into a futures contract, the Portfolios
   are required to deposit with a broker an amount of cash or securities equal
   to the minimum "initial margin" requirements of the associated futures
   exchange. Subsequent payments for futures contracts ("variation margin") are
   paid or received by the Portfolios, depending on the daily fluctuation in the
   value of the contracts, and are recorded by the Portfolios as unrealized
   gains or losses. When the contract is closed, the Portfolios realize a gain
   or loss equal to the difference between the opening and closing value of the
   contract. The use of futures contracts involves, to varying degrees, elements
   of market risk which may exceed the amounts recognized by the Portfolios.

                                       11
<Page>

   Changes in the value of the contracts may not directly correlate to the
   changes in the value of the underlying securities. These risks may decrease
   the effectiveness of the Portfolio's hedging and trading strategies and
   potentially result in a loss. As of June 30, 2003, Mid Cap Value Portfolio
   had no open contracts.

C. FOREIGN CURRENCY TRANSLATION
   The books and records of the Portfolio are maintained in U.S. dollars.
   Amounts denominated in foreign currencies are translated into U.S. dollars
   using current exchange rates.

   Net realized gains and losses on foreign currency transactions represent, the
   net realized gains and losses on foreign currency contracts, disposition of
   foreign currencies, and the difference between the amount of income accrued
   and the U.S. dollar actually received. Further, the effects of changes in
   foreign currency exchange rates on investments are not segregated in the
   statement of operations from the effects of changes in market price of those
   securities but are included with the net realized and unrealized gain or loss
   on investments.

D. FORWARD FOREIGN CURRENCY CONTRACTS
   The Portfolio enters into forward foreign currency contracts (contracts) for
   the purchase or sale of a specific foreign currency at a fixed price on a
   future date as a hedge or cross-hedge against either specific investment
   transactions (settlement hedges) or portfolio positions (portfolio hedges).
   All contracts are marked to market daily at the applicable exchange rates,
   and any resulting unrealized gains or losses are recorded in the Portfolios'
   financial statements. The Portfolio records realized gains and losses at the
   time a portfolio hedge is offset by entry into a closing transaction or
   extinguished by delivery of the currency. Risks may arise upon entering into
   these contracts from the potential inability of counterparties to meet the
   terms of the contract and from unanticipated movements in the value of
   foreign currencies relative to the U.S. dollar (see Note 8).

E. TAXES
   It is the Trust's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareowners. Therefore, no federal income tax provision is required.

   The characterization of distributions to shareowners for financial reporting
   purposes is determined in accordance with income tax rules. Therefore, the
   source of each Portfolio's distributions may be shown in the accompanying
   financial statements as either from or in excess of net investment income or
   net realized gain on investment transactions, or from paid-in capital,
   depending on the type of book/tax differences that may exist.

   Capital loss carryforwards are available to offset future realized capital
   gains. At December 31, 2002, Mid Cap Value VCT Portfolio had a capital loss
   carryforward of $879,730, which will expire in 2010 if not utilized.

                                       12

The following chart shows the components of distributable earnings (accumulated
losses) as of December 31, 2002 and the distributions paid during the year ended
December 31, 2002 on a tax basis as of December 31, 2002. The tax character of
current year distributions will be determined at the end of the current fiscal
year. These amounts do not include the capital loss carryforward detailed above.

</Table>

The difference between book-basis and tax-basis unrealized appreciation
(depreciation) is primarily attributable to the tax deferral of losses on wash
sales, returns of capital on REITs, and the recognition of unrealized gains or
losses on certain futures contracts.

F. PORTFOLIO SHARES
   The Portfolio records sales and repurchases of its shares as of trade date.
   Certain insurance companies paid Pioneer Funds Distributor, Inc. (PFD), the
   principal underwriter for the Trust and a wholly owned indirect subsidiary of
   UniCredito Italiano S.p.A. (UniCredito Italiano), $30,371 in commissions on
   the sale of portfolio shares for the six months ended June 30, 2003.
   Dividends and distributions to shareowners are recorded on the ex-dividend
   date.

G. SECURITY LENDING
   The Portfolio lends securities in its portfolio to certain broker-dealers or
   other institutional investors, with the Portfolios' custodian acting as the
   lending agent. When entering into a loan, the Portfolio receives collateral
   which is maintained by the custodian and earns income in the form of
   negotiated lenders' fees. The Portfolio also continues to receive interest or
   dividends on the securities loaned, and gain or loss in the fair value of the
   securities loaned that may occur during the term of the loan, will be for
   account of the Portfolio. The loans are secured by collateral of at least
   102%, at all times, of the fair value of the securities loaned. The fair
   value of the collateral will be adjusted daily to reflect any price
   fluctuation in the value of the loaned securities. The value of loaned
   securities and cash collateral at period end are disclosed on the balance
   sheet. The Trust invests cash collateral in the Securities Lending Investment
   Fund which is managed by Brown Brothers Harriman & Co., the Trust's
   custodian.

H. REPURCHASE AGREEMENTS
   With respect to repurchase agreements entered into by the Portfolio, the
   value of the underlying securities (collateral), including accrued interest
   received from counterparties, is required to be at least equal to or in
   excess of the value of the repurchase agreement at the time of purchase. The
   collateral for all repurchase agreements is held in safekeeping in the
   customer-only account of the Portfolio's custodian, or subcustodian. The
   Trust's investment adviser, Pioneer Investment Management, Inc. (PIM), is
   responsible for determining that the value of the collateral remains at least
   equal to the repurchase price.

2. MANAGEMENT AGREEMENT

PIM manages the Portfolio, and is a wholly owned indirect subsidiary of
UniCredito Italiano. Management fees are calculated daily at the following
annual rate of 0.65% of the Portfolios' average daily net assets.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Portfolio. At June 30, 2003, $133,523 was payable to
PIM related to management fees, administrative fees and certain other services.

3. TRANSFER AGENT

Pioneer Investment Management Shareholder Services, Inc. (PIMSS), a wholly owned
indirect subsidiary of UniCredito Italiano provides substantially all transfer
agent and shareowner services to the Trust at negotiated rates. Included in due
to affiliates is $118 in transfer agent fees payable to PIMSS at June 30, 2003.

Portfolio may close out such contracts by entering into an offsetting hedge
contract. As of June 30, 2003, the Portfolio had no open portfolio hedges. As of
June 30, 2003, the Portfolio had no open currency settlement contracts.
