Tax Exempt Trust



TRUST EXPENSES

TRUST EXPENSES. As a shareholder of the Trust, you incur ongoing costs,
including management fees; service fees; and other Trust expenses. These
examples are intended to help you understand your ongoing costs (in dollars) of
investing in the Trust and to compare these costs with the ongoing costs of
investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended December 31, 2008.

ACTUAL EXPENSES. The first section of the table provides information about
actual account values and actual expenses. You may use the information in
this section, together with the amount you invested, to estimate the
expense that you paid over the period. Simply divide your account value by
$1,000.00 (for example, an $8,600.00 account value divided by $1,000.00 =
8.60), then multiply the result by the number in the first section under
the heading entitled "Expenses Paid During Period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The second section of the table
provides information about hypothetical account values and hypothetical expenses
based on the Trust's actual expense ratio, and an assumed rate of return of 5%
per year before expenses, which is not the actual return. The hypothetical
account values and expenses may not be used to estimate the actual ending
account balance or expenses you paid for the period. You may use this
information to compare the ongoing costs of investing in the Trust and other
funds. To do so, compare this 5% hypothetical example with the 5% hypothetical
examples that appear in the shareholder reports of the other funds.

Expenses are equal to the Trust's annualized expense ratio, multiplied by the
average account value over the period, multiplied by 184/365 (to reflect the
one-half year period). The annualized expense ratio based on the 6-month period
ended December 31, 2008 is as follows:

EXPENSE RATIO

    0.66%

The "Financial Highlights" table in the Trust's financial statements, included
in this report, also show the gross expense ratio, without such waivers or
reimbursements and reduction to custodian expenses, if applicable.

FOOTNOTES TO STATEMENT OF INVESTMENTS Continued

(1.) Floating or variable rate obligation maturing in more than one year. The
     interest rate, which is based on specific, or an index of, market interest
     rates, is subject to change periodically and is the effective rate on
     December 31, 2008. This instrument has a demand feature which allows, on up
     to 30 days' notice, the recovery of principal at any time, or at specified
     intervals not exceeding one year.

(2.) Represents securities sold under Rule 144A, which are exempt from
     registration under the Securities Act of 1933, as amended. These securities
     have been determined to be liquid under guidelines established by the Board
     of Trustees. These securities amount to $524,819,499 or 25.52% of the
     Trust's net assets as of December 31, 2008.

(3.) Put obligation redeemable at full principal value on the date reported.

(4.) Illiquid security. The aggregate value of illiquid securities as of
     December 31, 2008 was $11,610,000, which represents 0.56% of the Trust's
     net assets. See Note 4 of accompanying Notes.

VALUATION INPUTS

Various data inputs are used in determining the value of each of the Trust's
investments as of the reporting period end. These data inputs are categorized in
the following hierarchy under applicable financial accounting standards:

     1) Level 1--quoted prices in active markets for identical assets or
     liabilities (including securities actively traded on a securities exchange)

     2) Level 2--inputs other than quoted prices that are observable for the
     asset (such as quoted prices for similar assets and market corroborated
     inputs such as interest rates, prepayment speeds, credit risks, etc.)

     3) Level 3--unobervable inputs (including the Manager's own judgments about
     assumptions that market participants would use in pricing the asset).

The market value of the Trust's investments was determined based on the
following inputs as of December 31, 2008:

*    Other financial instruments include options written, currency contracts,
     futures, forwards and swap contracts. Currency contracts and forwards are
     reported at their unrealized appreciation/depreciation at measurement date,
     which represents the change in the contract's value from trade date.
     Futures are reported at their variation margin at measurement date, which
     represents the amount due to/from the Trust at that date. Options written
     and swaps are reported at their market value at measurement date.

1. SIGNIFICANT ACCOUNTING POLICIES

Centennial Tax Exempt Trust (the "Trust") is registered under the Investment
Company Act of 1940, as amended, as an open-end management investment company.
The Trust's investment objective is to seek the maximum short-term interest
income exempt from federal income taxes that is consistent with low capital risk
and the maintenance of liquidity. The Trust's investment advisor is Centennial
Asset Management Corporation (the "Manager"), a subsidiary of OppenheimerFunds,
Inc. ("OFI").

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

SECURITIES VALUATION. The net asset value of shares of the Trust is normally
determined twice each day, at Noon Eastern time and at 4:00 P.M. Eastern time on
each day the New York Stock Exchange (the "Exchange") is open for trading.
Securities are valued at cost adjusted by the amortization of discount or
premium to maturity (amortized cost), which approximates market value. If
amortized cost is determined not to approximate market value, the fair value of
the portfolio securities will be determined under procedures approved by the
Trust's Board of Trustees.

     Effective for fiscal periods beginning after November 15, 2007, FASB
Statement of Financial Accounting Standards No. 157, FAIR VALUE MEASUREMENTS,
establishes a hierarchy for measuring fair value of assets and liabilities. As
required by the standard, each investment asset or liability of the Trust is
assigned a level at measurement date based on the significance and source of the
inputs to its valuation. Quoted prices in active markets for identical
securities are classified as "Level 1", inputs other than quoted prices for an
asset that are observable are classified as "Level 2" and unobservable inputs,
including the Manager's judgment about the assumptions that a market participant
would use in pricing an asset or liability are classified as "Level 3". The
inputs used for valuing securities are not necessarily an indication of the
risks associated with investing in those securities. A table summarizing the
Trust's investments under these levels of classification is included following
the Statement of Investments.

     "Money market-type" instruments are typically designated as Level 2.

     In the absence of a readily available quoted market price, including for
securities whose values have been materially affected by what the Manager
identifies as a significant event occurring before the Trust's assets are valued
but after the close of the securities' respective exchanges, the Manager, acting
through its internal valuation committee, in good faith determines the fair
valuation of that asset using consistently applied procedures under the
supervision of the Board of Trustees (which reviews those fair valuations by the
Manager). Those procedures include certain standardized methodologies to fair
value securities. Such methodologies include, but are not limited to, pricing
securities initially at cost and subsequently adjusting the value based on:
changes in company specific fundamentals, changes in an appropriate securities
index, or changes in the value of similar securities which may be adjusted for
any discounts related to resale restrictions. When possible, such methodologies
use observable market inputs such as quoted prices of similar securities,
observable interest

rates, currency rates and yield curves. The methodologies used for valuing
securities are not necessarily an indication of the risks associated with
investing in those securities.

     Fair valued securities may be classified as "Level 3" if the valuation
primarily reflects the Manager's own assumptions about the inputs that market
participants would use in valuing such securities.

     There have been no significant changes to the fair valuation methodologies
during the period.

FEDERAL TAXES. The Trust 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 to shareholders.
Therefore, no federal income or excise tax provision is required. The Trust
files income tax returns in U.S. federal and applicable state jurisdictions. The
statute of limitations on the Trust's tax return filings generally remain open
for the three preceding fiscal reporting period ends.

     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 Trust.

TRUSTEES' COMPENSATION. The Board of Trustees has adopted a compensation
deferral 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 Trust. 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 Trust or in other Oppenheimer funds
selected by the Trustee. The Trust purchases shares of the funds selected for
deferral by the Trustee in amounts equal to his or her deemed investment,
resulting in a Trust 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 Trust, and will not materially affect the
Trust's assets, liabilities or net investment income per share. Amounts will be
deferred until distributed in accordance to the compensation deferral plan.

DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations and
may differ from U.S. generally accepted accounting principles, are recorded on
the ex-dividend date. Income distributions, if any, are declared daily and paid
monthly. Capital gain distributions, if any, are declared and paid annually but
may be paid at other times to maintain the net asset value per share at $1.00.


                       F24 | CENTENNIAL TAX EXEMPT TRUST



INVESTMENT INCOME. Interest income is recognized on an accrual basis. Discount
and premium, which are included in interest income on the Statement of
Operations, are amortized or accreted daily.

CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Trust on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Trust pays
interest to its custodian on such cash overdrafts, to the extent they are not
offset by positive cash balances maintained by the Trust, at a rate equal to the
Federal Funds Rate plus 0.50%. The "Reduction to custodian expenses" line item,
if applicable, represents earnings on cash balances maintained by the Trust
during the period. Such interest expense and other custodian fees may be paid
with these earnings.

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.

INDEMNIFICATIONS. The Trust's organizational documents provide current and
former trustees and officers with a limited indemnification against liabilities
arising in connection with the performance of their duties to the Trust. In the
normal course of business, the Trust may also enter into contracts that provide
general indemnifications. The Trust's maximum exposure under these arrangements
is unknown as this would be dependent on future claims that may be made against
the Trust. The risk of material loss from such claims is considered remote.

OTHER. The preparation of financial statements in conformity with accounting
principles generally accepted in the United States of America 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 increases and
decreases in net assets from operations during the reporting period. Actual
results could differ from those estimates.

2. SHARES OF BENEFICIAL INTEREST

The Trust has authorized an unlimited number of no par value shares of
beneficial interest. Transactions in shares of beneficial interest were as
follows:

3. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Under the investment advisory agreement, the Trust pays the
Manager a management fee based on the daily net assets of the Trust at an annual
rate as shown in the following table:

FEE SCHEDULE


                  
Up to $250 million   0.500%
Next $250 million    0.475
Next $250 million    0.450
Next $250 million    0.425
Next $250 million    0.400
Next $250 million    0.375
Next $500 million    0.350
Over $2 billion      0.325


TRANSFER AGENT FEES. Shareholder Services, Inc. ("SSI") acts as the transfer and
shareholder servicing agent for the Trust. The Trust pays SSI a per account fee.
For the six months ended December 31, 2008, the Trust paid $231,351 to SSI for
services to the Trust.

SERVICE PLAN (12B-1) FEES. The Trust has adopted a Service Plan (the "Plan"). It
reimburses Centennial Asset Management Corporation (the "Distributor"), for a
portion of its costs incurred for services provided to accounts that hold shares
of the Trust. Reimbursement is made periodically depending on asset size, at an
annual rate of up to 0.20% of the average annual net assets of the Trust. The
Distributor currently uses all of those fees (together with significant amounts
from the Manager's own resources) to pay dealers, brokers, banks and other
financial institutions periodically for providing personal service and
maintenance of accounts of their customers that hold shares of the Trust. Fees
incurred by the Trust under the Plan are detailed in the Statement of
Operations.

WAIVERS AND REIMBURSEMENTS OF EXPENSES. Under the investment advisory agreement,
when the value of the Trust's net assets is less than $1.5 billion, the annual
fee payable to the Manager shall be reduced by $100,000 based on average net
assets computed daily and paid monthly at the annual rates. However, the annual
fee cannot be less than $0.

     The Manager has voluntarily undertaken to waive fees to the extent
necessary to assist the Trust in attempting to maintain a positive yield. There
is no guarantee that the Trust will maintain a positive yield. That undertaking
may be amended or withdrawn at any time.

     SSI has voluntarily agreed to limit transfer and shareholder servicing
agent fees to 0.35% of average annual net assets of the Trust. This undertaking
may be amended or withdrawn at any time.

4. ILLIQUID SECURITIES

As of December 31, 2008, investments in securities included issues that are
illiquid. Investments may be illiquid because they do not have an active trading
market, making it difficult to value them or dispose of them promptly at an
acceptable price. The Trust will not invest more than 10% of its net assets
(determined at the time of purchase and


                       F26 | CENTENNIAL TAX EXEMPT TRUST



reviewed periodically) in illiquid securities. Securities that are illiquid are
marked with an applicable footnote on the Statement of Investments.

5. TEMPORARY GUARANTEE PROGRAM FOR MONEY MARKET FUNDS

The Trust's Board of Trustees has elected for the Trust to participate in the
Temporary Guarantee Program for Money Market Funds (the "Program") established
by the U.S. Treasury Department. The Treasury Department has accepted the
Trust's application to participate in the Program and entered into a Guarantee
Agreement with the Trust dated as of September 19, 2008. The Trust has also
notified the Treasury Department of its intent to continue its participation in
the Program through April 30, 2009.

     Under the Program, shareholders of the Trust as of the close of business on
September 19, 2008 may be guaranteed against loss in the event that the Trust's
net asset value falls below $0.995. The Program applies only to shareholders of
record as of the close of business on September 19, 2008. The number of shares
covered by the Program will be the lesser of (a) the number of shares of the
Trust owned by the shareholder on September 19, 2008 or (b) the number of shares
owned by the shareholder on the date the Trust's net asset value falls below
$0.995. If the number of shares of the Trust a shareholder holds after September
19, 2008 fluctuates during the Program period due to purchases or redemptions of
shares, any shares in excess of the amount held as of the close of business on
September 19, 2008 will not be covered.

     The Trust has paid a fee to participate in the Program's initial term in
the amount equal to 0.01% of the Trust's net assets as of the close of business
on September 19, 2008. The Trust has paid an additional fee to continue its
participation in the Program through April 30, 2009 in the amount of 0.015% of
the Trust's net assets as of the close of business on September 19, 2008. Fees
paid by the Trust to participate in the Program are shown as insurance expense
on the Statement of Operations. Participation in any further extension of the
Program would require payment of an additional fee.

6. RECENT ACCOUNTING PRONOUNCEMENT

In March 2008, the Financial Accounting Standards Board ("FASB") issued
Statement on Financial Accounting Standards ("SFAS") No. 161, DISCLOSURES ABOUT
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES. This standard requires enhanced
disclosures about derivative and hedging activities, including qualitative
disclosures about how and why the Trust uses derivative instruments, how these
activities are accounted for, and their effect on the Trust's financial
position, financial performance and cash flows. SFAS No. 161 is effective for
financial statements issued for fiscal years and interim periods beginning after
November 15, 2008. At this time, management is evaluating the implications of
SFAS No. 161 and its impact on the Trust's financial statements and related
disclosures.

7. CHANGE IN INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

At a meeting held on August 20, 2008, the Board of Trustees of the Trust
appointed KPMG LLP as the independent registered public accounting firm to the
Trust for fiscal year 2009, replacing the firm of Deloitte & Touche LLP,
effective at the conclusion of the fiscal 2008 audit. During the two most recent
fiscal years the audit reports of Deloitte & Touche LLP contained no adverse
opinion or disclaimer of opinion and were not qualified or modified as to
uncertainty, audit scope or accounting principles. Further, there were no
disagreements between the Trust and Deloitte & Touche LLP on accounting
principles, financial statement disclosure or audit scope, which if not resolved
to the satisfaction of Deloitte & Touche LLP would have caused it to make
reference to the disagreements in connection with its reports.

8. SUBSEQUENT EVENT

The remaining shareholders of the Trust redeemed their shares on February 13,
2009. Following that redemption, the Trust commenced winding down its
operations.


                       F28 | CENTENNIAL TAX EXEMPT TRUST



BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited

Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew Centennial Tax
Exempt Trust's (the "Fund") investment advisory agreement (the "Agreement"). The
Investment Company Act of 1940, as amended, requires that the Board request and
evaluate, and that the Manager provide, such information as may be reasonably
necessary to evaluate the terms of the Agreement. The Board employs an
independent consultant to prepare a report that provides information, including
comparative information, the Board requests for that purpose. In addition, the
Board receives information throughout the year regarding Fund services, fees,
expenses and performance.

     The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services, (v) whether economies of scale
are realized as the Fund grows and whether fee levels reflect these economies of
scale for Fund investors and (vi) other benefits to the Manager from its
relationship with the Fund. The Board was aware that there are alternatives to
retaining the Manager.

     Outlined below is a summary of the principal information considered by the
Board as well as the Board's conclusions.

     NATURE, QUALITY AND EXTENT OF SERVICES. The Board considered information
about the nature, quality and extent of the services provided to the Fund and
information regarding the Manager's key personnel who provide such services. The
Manager's duties include providing the Fund with the services of the portfolio
manager and the Manager's investment team, who provide research, analysis and
other advisory services in regard to the Fund's investments; securities trading
services; oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing and supervising
all administrative and clerical personnel who are necessary in order to provide
effective corporate administration for the Fund; compiling and maintaining
records with respect to the Fund's operations; preparing and filing reports
required by the Securities and Exchange Commission; preparing periodic reports
regarding the operations of the Fund for its shareholders; preparing proxy
materials for shareholder meetings; and preparing the registration statements
required by Federal and state securities laws for the sale of the Fund's shares.
The Manager also provides the Fund with office space, facilities and equipment.


                         5 | CENTENNIAL TAX EXEMPT TRUST


BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited / Continued

     The Board also considered the quality of the services provided and the
quality of the Manager's resources that are available to the Fund. The Board
took account of the fact that the Manager has had over forty years of experience
as an investment adviser and that its assets under management rank it among the
top mutual fund managers in the United States. The Board evaluated the Manager's
advisory, administrative, accounting, legal and compliance services, and
information the Board has received regarding the experience and professional
qualifications of the Manager's key personnel and the size and functions of its
staff. In its evaluation of the quality of the portfolio management services
provided, the Board considered the experience of Carol Wolf, the portfolio
manager for the Fund, and the Manager's investment team and analysts. The Board
members also considered the totality of their experiences with the Manager as
Directors or Trustees of the Fund and other funds advised by the Manager. The
Board considered information regarding the quality of services provided by
affiliates of the Manager, which its members have become knowledgeable about in
connection with the renewal of the Fund's service agreements. The Board
concluded in light of the Manager's experience, reputation, personnel,
operations and resources, the Fund benefits from the services provided under the
Agreement.

     INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. Throughout the year,
the Manager provided information on the investment performance of the Fund and
the Manager, including comparative performance information. The Board also
reviewed information, prepared by the Manager and by the independent consultant,
comparing the Fund's historical performance to relevant market indices and to
the performance of other retail front-end load and no-load tax-exempt money
market funds advised by other investment advisers. The Board considered that the
Fund performed competitively vis-a-vis its performance universe median during
the one-, three-, five- and ten-year periods. The Board considered the Manager's
assertion that in the ten-year period the difference between the best and the
worst performer was only 0.9% and that the gross performance of the Fund
compared favorably to its peers.

     COSTS OF SERVICES BY THE MANAGER. The Board reviewed the fees paid to the
Manager and the other expenses borne by the Fund. The Board also considered the
comparability of the fees charged and the services provided to the Fund to the
fees and services for other clients or accounts advised by the Manager. The
independent consultant provided comparative data in regard to the fees and
expenses of the Fund and tax-exempt money market funds with comparable asset
levels and distribution features. The Board considered that the Fund's actual
management fees and total expenses were higher than its expense group median.


                         6 | CENTENNIAL TAX EXEMPT TRUST



     ECONOMIES OF SCALE AND PROFITS REALIZED BY THE MANAGER. The Board
considered information regarding the Manager's costs in serving as the Fund's
investment adviser, including the costs associated with the personnel and
systems necessary to manage the Fund, and information regarding the Manager's
profitability from its relationship with the Fund. The Board reviewed whether
the Manager may realize economies of scale in managing and supporting the Fund.
The Board noted that the Fund currently has management fee breakpoints, which
are intended to share with Fund shareholders economies of scale that may exist
as the Fund's assets grow.

     OTHER BENEFITS TO THE MANAGER. In addition to considering the profits
realized by the Manager, the Board considered information that was provided
regarding the direct and indirect benefits the Manager receives as a result of
its relationship with the Fund, including compensation paid to the Manager's
affiliates. The Board also considered that the Manager must be able to pay and
retain experienced professional personnel at competitive rates to provide
quality services to the Fund and that maintaining the financial viability of the
Manager is important in order for the Manager to continue to provide significant
services to the Fund and its shareholders.

     CONCLUSIONS. These factors were also considered by the independent Trustees
meeting separately from the full Board, assisted by experienced counsel to the
Fund and to the independent Trustees. Fund counsel and the independent Trustees'
counsel are independent of the Manager within the meaning and intent of the
Securities and Exchange Commission Rules.

     Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
decided to continue the Agreement for another year. In arriving at this
decision, the Board did not single out any factor or factors as being more
important than others, but considered all of the above information, and
considered the terms and conditions of the Agreement, including the management
fee, in light of all of the surrounding circumstances.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance Committee (the "Committee") will evaluate potential
      Board candidates to assess their qualifications. The Committee shall have
      the authority, upon approval of the Board, to retain an executive search
      firm to assist in this effort. The Committee may consider recommendations
      by business and personal contacts of current Board members and by
      executive search firms which the Committee may engage from time to time
      and may also consider shareholder recommendations. The Committee may
      consider the advice and recommendation of the Funds' investment manager
      and its affiliates in making the selection.

2.    The Committee shall screen candidates for Board membership. The Committee
      has not established specific qualifications that it believes must be met
      by a trustee nominee. In evaluating trustee nominees, the Committee
      considers, among other things, an individual's background, skills, and
      experience; whether the individual is an "interested person" as defined in
      the Investment Company Act of 1940; and



      whether the individual would be deemed an "audit committee financial
      expert" within the meaning of applicable SEC rules. The Committee also
      considers whether the individual's background, skills, and experience will
      complement the background, skills, and experience of other nominees and
      will contribute to the Board. There are no differences in the manner in
      which the Committee evaluates nominees for trustees based on whether the
      nominee is recommended by a shareholder.

3.    The Committee may consider nominations from shareholders for the Board at
      such times as the Committee meets to consider new nominees for the Board.
      The Committee shall have the sole discretion to determine the candidates
      to present to the Board and, in such cases where required, to
      shareholders. Recommendations for trustee nominees should, at a minimum,
      be accompanied by the following:

      -     the name, address, and business, educational, and/or other pertinent
            background of the person being recommended;

      -     a statement concerning whether the person is an "interested person"
            as defined in the Investment Company Act of 1940;

      -     any other information that the Funds would be required to include in
            a proxy statement concerning the person if he or she was nominated;
            and

      -     the name and address of the person submitting the recommendation
            and, if that person is a shareholder, the period for which that
            person held Fund shares.

      The recommendation also can include any additional information which the
      person submitting it believes would assist the Committee in evaluating the
      recommendation.

4.    Shareholders should note that a person who owns securities issued by
      Massachusetts Mutual Life Insurance Company (the parent company of the
      Funds' investment adviser) would be deemed an "interested person" under
      the Investment Company Act of 1940. In addition, certain other
      relationships with Massachusetts Mutual Life Insurance Company or its
      subsidiaries, with registered broker-dealers, or with the Funds' outside
      legal counsel may cause a person to be deemed an "interested person."

5.    Before the Committee decides to nominate an individual as a trustee,
      Committee members and other directors customarily interview the individual
      in person. In addition, the individual customarily is asked to complete a
      detailed questionnaire which is designed to elicit information which must
      be disclosed under SEC and stock exchange rules and to determine whether
      the individual is subject to any statutory disqualification from serving
      as a trustee of a registered investment company.



ITEM 11. CONTROLS AND PROCEDURES.

Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 12/31/2008, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the 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.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.

ITEM 12. EXHIBITS.

(a)   (1) Not applicable to semiannual reports.

      (2) Exhibits attached hereto.

      (3) Not applicable.

(b)   Exhibit attached hereto.
