Dear Shareholder:

The second half of 1996 was a period of uncertainty in the fixed income
markets, largely due to investor fears of rapid economic growth and
accelerating inflation. The 30-year Treasury rates rose above 7% in the second
quarter and remained relatively unchanged until the end of the third quarter.
That's when negative investor sentiment that led to the market downturn in June
and July began to subside.

The swing away from inflationary fears seemed complete in October with the
release of economic indicators showing a firm dollar, low inflation and slow
growth. When the Federal Reserve responded to these indicators with another
decision to leave rates alone, it appeared that concerns about rapid growth had
been overblown, and interest rates fell in response. The status quo outcome of
the presidential election also aided the decline in rates, and the bond market
experienced one of the most substantial post-election rallies in recent
history. With continued, sustainable non-inflationary growth of around 2% to
2.5%, and long-term rates at their lowest levels since April, the economy seems
to have settled into a comfortable path of neither too little nor too much
growth.

Centennial Tax Exempt Trust performed well due to our bullish outlook on
interest rates. In the early part of 1996, we believe that the Fed would be
hesitant to raise rates as long as inflation didn't accelerate wildly. In
response, we extended the portfolio's duration and took advantage of the higher
returns that usually accompany longer-duration bonds. Later in the summer, as
it became accepted among analysts that the Fed was probably less inclined to
raise rates, we began to be even more aggressive in lengthening the portfolio's
maturity.

In the second half of 1996, rates declined quite a bit so we backed away from
the longer maturities and monitored year-end activity. We expect that the
economy will continue to slowly decelerate.

The Trust had a compounded annualized yield of 2.99% for the six months ended
December 31, 1996. Without compounding, the corresponding yield was 2.95%. For
investors in the 36% federal tax bracket, this is equivalent to a taxable yield
for six months of 4.67% with compounding, and 4.61% without. The seven-day
annualized yields, with and without compounding for the six-month period ended
December 31, 1996 were 3.31% and 3.26%, respectively.(1)

Sincerely,

NOTES TO FINANCIAL STATEMENTS (Unaudited)
Centennial Tax Exempt Trust


1.  SIGNIFICANT ACCOUNTING POLICIES

Centennial Tax Exempt Trust (the Trust) is registered under the Investment
Company Act of 1940, as amended, as a diversified, 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 by investing in
short-term municipal securities. The Trust's investment adviser 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. 

Investment Valuation - Portfolio securities are valued on the basis of amortized
cost, which approximates market value.

Federal Taxes - The Trust intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to shareholders. Therefore, no federal
income or excise tax provision is required. 

Distributions to Shareholders - The Trust intends to declare dividends from net
investment income each day the New York Stock Exchange is open for business and
pay such dividends monthly. To effect its policy of maintaining a net asset
value of $1.00 per share, the Trust may withhold dividends or make distributions
of net realized gains.

Other - Investment transactions are accounted for on the date the investments
are purchased or sold (trade date). Realized gains and losses on investments are
determined on an identified cost basis, which is the same basis used for federal
income tax purposes.

The preparation of financial statements in conformity with 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.


                                                                              17

3. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Management fees paid to the Manager were in accordance with the investment
advisory agreement with the Trust which provides for a fee of 0.50% on the first
$250 million of average annual net assets with a reduction of 0.025% on each
$250 million thereafter to $1.5 billion, 0.35% on the next $500 million of net
assets and 0.325% on net assets in excess of $2 billion. Until Trust net assets
reach $1.5 billion, the annual fee payable to the Manager will be reduced by
$100,000. The Manager has agreed to assume Trust expenses (with specified
exceptions) in excess of the most stringent applicable regulatory limit on Trust
expenses. 

Shareholder Services, Inc. (SSI), a subsidiary of OFI, is the transfer and
shareholder servicing agent for the Trust, and for other registered investment
companies. SSI's total costs of providing such services are allocated ratably to
these companies.

Expenses paid indirectly represent a reduction of custodian fees for earnings on
cash balances maintained by the fund.

Under an approved service plan, the Trust may expend up to 0.20% of its net
assets annually to reimburse Centennial Asset Management Corporation, as
distributor, for costs incurred in connection with the personal service and
maintenance of accounts that hold shares of the Trust, including amounts paid to
brokers, dealers, banks and other institutions. During the six months ended
December 31, 1996, the Trust paid $3,529 to a broker/dealer affiliated with the
Manager as reimbursement for distribution-related expenses.
