FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JUNE 30, 2004, FOLLOWED BY A
GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. The Oppenheimer Main Street Small
Cap Fund enjoyed strong absolute returns during a mostly positive climate for
small-cap stock investing. The first six months were a particularly favorable
environment for the Fund, although performance was more subdued during the
second half of the period as stocks gave back some of their gains in response to
investors' fears of rising interest rates. The Fund's performance closely
tracked the Russell 2000 Index over this period. See page 2 for detailed
performance information.

      The market environment for the Fund during the past 12 months can be
roughly divided into two parts. During the first part of the reporting period,
from July 1, 2003, until the second half of January 2004, stocks gained as
investors became more confident about economic growth and rising corporate
earnings. As their conviction increased that the economic rebound was
sustainable, investors became more willing to buy stocks instead of lower-risk
bonds. Against this backdrop, small-cap stocks, with their greater growth
potential, were the greatest beneficiaries. In particular, the smallest of these
stocks--so-called "micro caps"--as well as aggressive names in growth-oriented
sectors such as technology did especially well.

      During the second part of the period, an increasing amount of data pointed
to rising inflation accompanying the fast-growing economy. This fact was
expected to convince the Federal Reserve Board to increase interest rates off of
their historic lows (an expectation that was met on June 30, 2004). The threat
of higher rates weighed on stock prices and reversed the growth trend in the
small-cap market. Gains in micro-cap and fundamentally weak technology stocks
were interrupted, and larger-cap and higher-quality names began enjoying
stronger results on a relative basis.

      When selecting small-cap securities for the Fund, we use a proprietary
stock-selection model. This model leads us to those companies with
characteristics that have predicted success historically. As the 12-month
reporting period began, our model detected improvements in the economy and was
steering us toward technology and other cyclical investments that were expected
to benefit. Our model also led us to increase the Fund's weighting in micro-cap
stocks, from approximately 36% to 40% of the portfolio, while de-emphasizing
more defensive areas of the market such as consumer staples, utilities and parts
of the health care sector. These positioning decisions benefited performance
during the first part of the period.


                  10 | OPPENHEIMER MAIN STREET SMALL CAP FUND


      Toward the end of the period, our model was increasingly recommending a
shift away from micro caps and relatively aggressive growth stocks and into
larger companies as well as certain higher-quality cyclical stocks. For example,
we invested in selected companies in the industrials sector, which historically
has benefited most in the middle to later stages of an economic recovery. We
also purchased stocks in the energy and consumer discretionary sectors, both of
which we overweighted throughout the past 12 months. In hindsight, this shift in
emphasis proved to be a good move. However, our model did not anticipate the
shift quickly enough, and the delay resulted in a performance lag relative to
our benchmark and peers.

      The significant position we maintained in the energy sector proved
beneficial to the Fund as energy stocks outperformed primarily due to sharply
rising oil prices. The Fund's performance was also positively influenced by
emphasizing the consumer discretionary sector, which fared well as companies
continued to benefit from the expanding economy and continued strength in
consumer spending. The Fund's limited position in financials and utilities also
helped performance; financials were hurt as investors grew concerned about the
impact of rising interest rates, while utilities and other defensive investments
historically have been overlooked during times of economic growth.

      On the negative side, the Fund's relative performance was hurt by stock
selection within the technology sector. Early in the period, our model was
somewhat late in detecting a market shift and recommending a move in favor of
more aggressive, smaller-cap technology stocks. In addition, primarily in March
and April 2004, when market conditions changed to favor less aggressive and
larger small-cap technology names, we were unable to react quickly enough and
wound up owning certain underperforming stocks for longer than desirable. In
fact, many of the securities proving to be laggards late in the period were the
same names that had generated large gains for the Fund during the previous eight
months. We have however, greatly reduced the Fund's exposure to micro caps. As
previously mentioned, the Fund's exposure to micro caps was approximately 40%
during the period. We have since greatly reduced this allocation to 28%, and are
working to further reduce it, in anticipation of more favorable performance for
the larger companies within the small-cap market.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until June 30, 2004. In the case of Class A, Class B, Class C and
Class Y shares, performance is measured from inception of the classes on August
2, 1999. In the case of Class N shares, performance is measured from inception
of the class on March 1, 2001. The Fund's performance reflects the deduction of
the maximum initial sales charge on Class A

FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

shares, the applicable contingent deferred sales charge on Class B, Class C and
Class N shares, and reinvestments of all dividends and capital gains
distributions. Past performance cannot guarantee future results.

      The Fund's performance is compared to the performance of the Russell 2000
Index and the Lipper Small-Cap Core Fund Index. The Russell 2000 Index is an
unmanaged index of small-capitalization stocks. The Lipper Small-Cap Core Fund
category includes the 30 largest mutual funds within the investment category as
defined by Lipper. Index performance reflects the reinvestment of income but
does not consider the effect of transaction costs, and none of the data in the
graphs shows the effect of taxes. The Fund's performance reflects the effects of
the Fund's business and operating expenses. While index comparisons may be
useful to provide a benchmark for the Fund's performance, it must be noted that
the Fund's investments are not limited to the investments in the index.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Main Street Small Cap Fund (the Fund) is an open-end management
investment company registered under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to seek capital appreciation. The
Fund's investment advisor is OppenheimerFunds, Inc. (the Manager).

      The Fund offers Class A, Class B, Class C, Class N and Class Y shares.
Class A shares are sold at their offering price, which is normally net asset
value plus a front-end sales charge. Class B, Class C and Class N shares are
sold without a front-end sales charge but may be subject to a contingent
deferred sales charge (CDSC). Class N shares are sold only through retirement
plans. Retirement plans that offer Class N shares may impose charges on those
accounts. Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC. All classes of shares have identical
rights and voting privileges with respect to the Fund in general and exclusive
voting rights on matters that affect that class alone. Earnings, net assets and
net asset value per share may differ due to each class having its own expenses,
such as transfer and shareholder servicing agent fees and shareholder
communications, directly attributable to that class. Classes A, B, C and N have
separate distribution and/or service plans. No such plan has been adopted for
Class Y shares. Class B shares will automatically convert to Class A shares six
years after the date of purchase.

      The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Fund calculates the net asset value of its shares as
of the close of The New York Stock Exchange (the Exchange), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities listed
or traded on National Stock Exchanges or other domestic or foreign exchanges are
valued based on the last sale price of the security traded on that exchange
prior to the time when the Fund's assets are valued. Securities traded on NASDAQ
are valued based on the closing price provided by NASDAQ prior to the time when
the Fund's assets are valued. In the absence of a sale, the security is valued
at the last sale price on the prior trading day, if it is within the spread of
the closing bid and asked prices, and if not, at the closing bid price.
Securities may be valued primarily using dealer-supplied valuations or a
portfolio pricing service authorized by the Board of Trustees. Securities
(including restricted securities) for which market quotations are not readily
available are valued at their fair value. Foreign and domestic securities whose
values have been materially affected by what the Manager identifies as a
significant event occurring before the Fund's assets are valued but after the
close of their respective exchanges will be fair valued. Fair value is
determined in good faith using consistently applied procedures under the
supervision of the Board of Trustees. Short-term "money market type" debt
securities with remaining maturities of sixty days or less are valued at
amortized cost (which approximates market value).

1. SIGNIFICANT ACCOUNTING POLICIES Continued

FOREIGN CURRENCY TRANSLATION. The Fund's accounting records are maintained in
U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars as of the close of The New York Stock Exchange.
Amounts related to the purchase and sale of foreign securities and investment
income are translated at the rates of exchange prevailing on the respective
dates of such transactions. Foreign exchange rates may be valued primarily using
dealer supplied valuations or a portfolio pricing service authorized by the
Board of Trustees.

      Reported net realized foreign exchange gains or losses arise from sales of
portfolio securities, sales and maturities of short-term securities, sales of
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
values of assets and liabilities, including investments in securities at fiscal
period end, resulting from changes in exchange rates.

      The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Fund's Statement of Operations.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders, therefore, no federal income or excise tax provision is
required.

The tax components of capital shown in the table below represent distribution
requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be able to offset against income and gains realized in future years and
unrealized appreciation or depreciation of securities and other investments for
federal income tax purposes.

1. During the fiscal year ended June 30, 2004, the Fund utilized $70,002,232 of
capital loss carryforward to offset capital gains realized in that fiscal year.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for June 30, 2004. Net assets of the
Fund were unaffected by the reclassifications.

                                                                 REDUCTION TO

2. $13,062,750, all of which was long-term capital gain, was distributed in
connection with Fund share redemptions.

No distributions were paid during the years ended June 30, 2004 and June 30,
2003.

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of June 30, 2004 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments, if applicable, is attributable to the tax deferral of losses
or tax realization of financial statement unrealized gain or loss.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

TRUSTEES' COMPENSATION. The Board of Trustees has adopted a deferred
compensation plan for independent trustees that enables trustees to elect to
defer receipt of all or a portion of the annual compensation they are entitled
to receive from the Fund. For purposes of determining the amount owed to the
Trustee under the plan, deferred amounts are treated as though equal dollar
amounts had been invested in shares of the Fund or in other Oppenheimer funds
selected by the Trustee. The Fund does purchase shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Fund asset equal to the deferred compensation liability. Such
assets are included as a component of "Other" within the asset section of the
Statement of Assets and Liabilities. Deferral of trustees' fees under the plan
will not affect the net assets of the Fund, and will not materially affect the
Fund's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable,
represents earnings on cash balances maintained by the Fund.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager,
acts as the transfer and shareholder servicing agent for the Fund. The Fund pays
OFS a per account fee. For the year ended June 30, 2004, the Fund paid
$4,601,748 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 for
assets of $10 million or more. The Class Y shares are subject to the minimum
fees in the event that the per account fee does not equal or exceed the
applicable minimum fees. OFS may voluntarily waive the minimum fees.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- --------------------------------------------------------------------------------
SERVICE PLAN FOR CLASS A SHARES. The Fund has adopted a Service Plan for Class A
shares. It reimburses the Distributor for a portion of its costs incurred for
services provided to accounts that hold Class A shares. Reimbursement is made
quarterly at an annual rate of up to 0.25% of the average annual net assets of
Class A shares of the Fund. The Distributor currently uses all of those fees to
pay dealers, brokers, banks and other financial institutions quarterly for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
years. Fees incurred by the Fund under the Plan are detailed in the Statement of
Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
distribution of those shares and servicing accounts. Under the plans, the Fund
pays the Distributor an annual asset-based sales charge of 0.75% per year on
Class B shares and on Class C shares and 0.25% per year on Class N shares. The
Distributor also receives a service fee of up to 0.25% per year under each plan.
If either the Class B, Class C or Class N plan is terminated by the Fund or by
the shareholders of a class, the Board of Trustees and its independent trustees
must determine whether the Distributor shall be entitled to payment from the
Fund of all or a portion of the service fee and/or asset-based sales charge in
respect to shares sold prior to the effective date of such termination. The
Distributor's aggregate uncompensated expenses under the plan at June 30, 2004
for Class B, Class C and Class N shares were $7,850,039, $4,289,234 and
$1,149,185, respectively. Fees incurred by the Fund under the plans are detailed
in the Statement of Operations.

SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the table below for the period indicated.

Manager paid the Fund $21,974, an amount equivalent to certain of such
commissions incurred in prior years.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class.
During the year ended June 30, 2004, OFS waived $5,541, $9,727, $4,002 and
$58,914 for Class A, Class B, Class C and Class N shares, respectively. This
undertaking may be amended or withdrawn at any time.

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

5. FOREIGN CURRENCY CONTRACTS

A foreign currency contract is a commitment to purchase or sell a foreign
currency at a future date, at a negotiated rate. The Fund may enter into foreign
currency contracts to settle specific purchases or sales of securities
denominated in a foreign currency and for protection from adverse exchange rate
fluctuation. Risks to the Fund include the potential inability of the
counterparty to meet the terms of the contract.

      The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using prevailing foreign currency exchange rates.
Unrealized appreciation and depreciation on foreign currency contracts are
reported in the Statement of Assets and Liabilities as a receivable or payable
and in the Statement of Operations with the change in unrealized appreciation or
depreciation.

      The Fund may realize a gain or loss upon the closing or settlement of the
foreign transaction. Contracts closed or settled with the same broker are
recorded as net realized gains or losses. Such realized gains and losses are
reported with all other foreign currency gains and losses in the Statement of
Operations.

      As of June 30, 2004, the Fund had no outstanding foreign currency
contracts.

6. ILLIQUID OR RESTRICTED SECURITIES

As of June 30, 2004, investments in securities included issues that are illiquid
or restricted. Restricted securities are purchased in private placement
transactions, are not registered under the Securities Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as reflecting fair value. A security may also be considered
illiquid if it lacks a readily available market or if its valuation has not
changed for a certain period of time. The Fund intends to invest no more than
10% of its net assets (determined at the time of purchase and reviewed
periodically) in illiquid or restricted securities. Certain restricted
securities, eligible for resale to qualified institutional investors, are not
subject to that limitation. The aggregate value of illiquid or restricted
securities subject to this limitation as of June 30, 2004 was $2,667,460, which
represents 0.12% of the Fund's net assets, of which $1,114,613 is considered
restricted. Information concerning restricted securities is as follows:

7. SECURITIES LENDING

The Fund lends portfolio securities from time to time in order to earn
additional income. In return, the Fund receives collateral in the form of US
Treasury obligations or cash, against the loaned securities and maintains
collateral in an amount not less than 100% of the market value of the loaned
securities during the period of the loan. The market value of the loaned
securities is determined at the close of business of the funds and any
additional required collateral is delivered to the Fund on the next business
day. If the borrower defaults on its obligation to return the securities loaned
because of insolvency or other reasons, the Fund could experience delays and
cost in recovering the securities loaned or in gaining access to the collateral.
Cash collateral is invested in cash equivalents. The Fund retains a portion of
the interest earned from the collateral. The Fund also continues to receive
interest or dividends paid on the securities loaned. As of June 30, 2004, the
Fund had on loan securities valued at approximately $404,629,000. Cash of
$410,325,548 was received as collateral for the loans, and has been invested in
approved instruments.

THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
OPPENHEIMER MAIN STREET SMALL CAP FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Main Street Small Cap Fund, including the statement of investments,
as of June 30, 2004, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in 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 the standards of the Public
Company Accounting Oversight Board (United States). 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 June 30, 2004, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other 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
Oppenheimer Main Street Small Cap Fund as of June 30, 2004, 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 the
periods indicated, in conformity with accounting principles generally accepted
in the United States of America.

regarding all dividends and distributions paid to them by the Fund during
calendar year 2004. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

      Dividends, if any, paid by the Fund during the fiscal year ended June 30,

lower individual income tax rates to the extent that the Fund has received
qualified dividend income as stipulated by recent tax legislation. In early

ITEM 9.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         The Board is responsible for approving nominees for election as
trustees. To assist in this task, the Board has designated the Audit Committee
as the nominating committee for the Board. It reviews and recommends nominees to
the Board. The Committee is comprised entirely of disinterested trustees as
defined in Section 2(a)(19) of the Investment Company Act of 1940.

The Audit Committee charter describes the responsibilities of the Committee in
nominating candidates for election as independent Trustees of the Registrant.
The Registrant's Board has adopted a written charter for the Committee. A
current copy of the Audit Committee charter is available to shareholders on the
OppenheimerFunds website at www.oppenheimerfunds.com.

Under the current policy, if the Board determines that a vacancy exists or is
likely to exist on the Board, the Audit Committee of the Board will consider
candidates for Board membership including recommended by Registrant
shareholders. The Audit Committee will consider nominees recommended by
independent Board members or recommended by any other Board members including
Board members affiliated with the Registrant's investment advisors. The
Committee may, upon Board approval, retain an executive search firm to assist in
screening potential candidates. Upon Board approval, the Audit Committee may
also use the services of legal, financial, or other external counsel that it
deems necessary or desirable in the screening process. Shareholders wishing to
submit a nominee for election to the Board may do so by mailing their submission
to the offices of OppenheimerFunds, Inc., 6803 South Tucson Way, Centennial, CO
80112, to the attention of the Board of Trustees of the named Registrant, c/o
the Secretary of the Registrant.

The Committee's process for identifying and evaluating nominees for trustees
includes a number of factors. In screening candidates for board membership,
whether the candidate is suggested by Board members, shareholders or others, the
Committee considers the candidate's professional experience, soundness of
judgment, integrity, ability to make independent, analytical inquiries,
collegiality, willingness and ability to devote the time required to perform
Board activities adequately, ability to represent the interests of all
shareholders of the Registrant, and diversity relative to the board's
composition. Candidates are expected to provide a mix of attributes, experience,
perspective and skills necessary to effectively advance the interests of
shareholders.

              procedures (as defined in rule 30a-2(c) under the Investment

              provide reasonable assurances that information required to be
              disclosed by registrant in the reports that it files under the
              Securities Exchange Act of 1934 (a) is accumulated and
              communicated to registrant's management, including its principal
              executive officer and principal financial officer, to allow timely
              decisions regarding required disclosure, and (b) is recorded,
              processed, summarized and reported, within the time periods
              specified in the rules and forms adopted by the U.S. Securities
              and Exchange Commission.

         (b)  There have been no significant changes in registrant's internal
              controls over financial reporting that occurred during the
              registrant's last fiscal half-year that has materially affected,
              or is reasonably likely to materially affect, the registrant's
              internal control over financial reporting.
