</TABLE>

All total returns are through December 31, 1997, and reflect the reinvestment 
of distributions but not sales charges. NAV-based performance is used to 
measure investment management results. As noted in earlier shareholder 
reports, we no longer compare the funds' NAV performance to a market 
benchmark. This is because our primary goal is to meet the funds' investment 
objectives of providing high current income exempt from regular federal and 
state of Minnesota personal income tax and returning $10 per share to 
investors at the funds' termination dates. 

Average annualized total returns based on the change in market price for the 
one-year, five-year and since inception periods ended December 31, 1997, were 
12.48%, 7.53% and 7.67% for MNA and 10.78%, 6.66% and 7.04% for MNB. These 
returns assume reinvestment of all distributions and reflect sales charges on 
those distributions described in the funds' dividend reinvestment plan, but 
not on initial purchases.

PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THESE INVESTMENTS. NEITHER SAFETY 
OF PRINCIPAL NOR STABILITY OF INCOME IS GUARANTEED. Past performance does not 
guarantee future results. The investment return and principal value of an 
investment will fluctuate so that fund shares, when sold, may be worth more 
or less than their original cost. Closed-end funds, such as these funds, 
often trade at discounts to net asset value. Therefore, you may be unable to 
realize the full net asset value of your shares when you sell.

                   DEAR SHAREHOLDERS:

[PHOTO]            WE ARE PLEASED THAT THE MINNESOTA MUNICIPAL TERM TRUSTS 
                   (MNA AND MNB) REMAINED ON TARGET TO MEET THEIR INVESTMENT 
                   OBJECTIVES OF PROVIDING HIGH TAX-EXEMPT INCOME AND 
                   RETURNING $10 PER SHARE TO INVESTORS ON OR SHORTLY BEFORE 
                   THEIR TERMINATION DATES. For the year ended December 31, 
                   1997, the funds continued to earn more than their monthly 
DOUG WHITE, CFA,   common and preferred stock+ dividends and add to their 
shares             dividend reserves. Since the funds' inceptions, the funds 
responsibility     have maintained monthly common stock distributions of 
for the            5.09 cents and 4.92 cents per share, respectively. In 
management         addition, the funds' net asset values remain above the 
of the Minnesota   $10 per share objective. As of December 31, 1997, the net

                   Economically speaking, the year had a strong start, 
                   prompting the Federal Reserve Board to raise the federal 
                   funds rate in March from 5.25% to 5.50%, which caused 
                   bond yields to rise and prices to fall. By April, the 
                   economy showed signs of slowing, sending interest rates 
                   down and bond prices up, a trend that reversed again

                   fourth quarter, the expectation of continued 
[PHOTO]            moderate economic growth, low inflation and a 
                   flight-to-quality resulting from the Asian turmoil 
                   fueled a U.S. bond market rally. Given the lack of 
                   direct foreign demand for municipal issues, 
                   municipal yields decreased more slowly than Treasury 
                   yields. This, along with an increase in municipal 
RON REUSS, ISFA,   issues, caused the municipal market to underperform 
shares             its taxable counterpart during the last quarter of 
responsibility     the year. During 1997, the national supply of

28 years of        CONTINUE TO SELL LONGER MATURITY BONDS IN FAVOR OF 
financial          THOSE CLOSER TO THE FUNDS' TERMINATIONS. As shown in 
experience.        the chart below, the percentage of bonds with

                   funds' termination dates continues to increase. We 
                   made appropriate trades as opportunities arose. As 
                   interest rates fell during the year and bond prices 
                   increased, restructuring generated capital gains, 
                   which were distributed. Also, restructuring proceeds 
                   were reinvested at lower interest rates, decreasing 
                   fund income. Advance refunding+ is responsible for a 
                   portion of the increase in the percentages shown in 
                   the chart.

                   WE EXPECT THAT THE FUNDS' NET ASSET VALUES WILL

                   these bonds approach, their market prices will 
                   converge toward a price that is at or near their 
                   maturity or refunding prices. In addition, as the 
                   funds approach termination, we continue to sell 
                   longer maturity bonds in favor of bonds with shorter 
                   maturities and lower coupons+ that come due closer 
                   to the funds' termination dates. Any gains realized 
                   as a result of these sales will be distributed to 
                   shareholders, reducing net asset value. If the 
                   shorter-maturity bonds pay insufficient income to 
                   maintain our current dividends, the funds' dividend 
                   reserves may be used to pay common and/or preferred 
                   dividends. See the chart below for each fund's 
                   current accumulated realized+ gains, unrealized+ 
                   appreciation and current dividend reserve. 
                   Shareholders also should remember that the funds are 
                   always subject to interest rate risk+ and credit 
                   risk,+ which could have an impact on net asset 
                   value.

                   WE ARE OPTIMISTIC ABOUT THE MUNICIPAL MARKET 
                   DURING THE COMING MONTHS, AND AGAIN, WE DON'T 
                   ANTICIPATE EVENTS THAT WOULD CAUSE US TO CHANGE THE 
                   FUNDS' INVESTMENT STRATEGY AS THEY MOVE TOWARD 
                   TERMINATION. However, we remain watchful for further
                   negative news about Asian economies or a significant 
                   increase in the number of municipal bond refundings 
                   due to lower interest rates

(2) SUMMARY OF
    SIGNIFICANT
    ACCOUNTING
    POLICIES
 ................................
                  INVESTMENTS IN SECURITIES
               Portfolio securities for which market quotations are readily
               available are valued at current market value. If market
               quotations or valuations are not readily available, or if such
               quotations or valuations are believed to be inaccurate,
               unreliable or not reflective of market value, portfolio
               securities are valued according to procedures adopted by the
               funds' board of directors in good faith at "fair value", that is,
               a price that the funds might reasonably expect to receive for the
               security or other asset upon its current sale.
 
               The current market value of certain fixed income securities is
               provided by an independent pricing service. Fixed income
               securities for which prices are not available from an independent
               pricing service but where an active market exists are valued
               using market quotations obtained from one or more dealers that
               make markets in the securities or from a widely-used quotation
               system. Short-term securities with maturities of 60 days or less
               are valued at amortized cost, which approximates market value.

               Securities transactions are accounted for on the date securities
               are purchased or sold. Realized gains and losses are calculated
               on the identified-cost basis. Interest income, including
               amortization of bond discount and premium, is recorded on an
               accrual basis.
 
               The funds concentrate their investments in Minnesota and,
               therefore, may have more credit risk related to the economic
               conditions of Minnesota than portfolios with a broader
               geographical diversification.
 
                  SECURITIES PURCHASED ON A WHEN-ISSUED BASIS
               Delivery and payment for securities that have been purchased by
               the funds on a when-issued or forward-commitment basis can take
               place a month or more after the transaction date. During this
               period, such securities do not earn interest, are subject to
               market fluctuation and may increase or decrease in value prior to
               their delivery. The funds segregate, with their custodian, assets
               with a market value equal to the amount of their purchase
               commitments. The purchase of securities on a when-issued or
               forward-commitment basis may increase the volatility of the
               funds' net asset value if the funds make such purchases while
               remaining substantially fully invested. As of December 31, 1997,
               Minnesota Municipal Term Trust Inc. and Minnesota Municipal Term
               Trust Inc. II, had entered into outstanding when-issued or
               forward commitments of $1,605,838, and $2,001,056, respectively.
 
                  FEDERAL TAXES
               Each fund is treated separately for federal income tax purposes.
               Each fund intends to comply with the requirements of the Internal
               Revenue Code applicable to regulated investment companies and not
               be subject to federal income tax. Therefore, no income tax
               provision is required. The funds also intend to distribute their
               taxable net investment income and realized gains, if any, to
               avoid the payment of any federal excise taxes.
 
               Net investment income and net realized gains (losses) may differ
               for financial statement and tax purposes primarily because of

               market discount amortization. The character of distributions made
               during the year from net investment income or net realized gains
               may differ from its ultimate characterization for federal income
               tax purposes. In addition, due to the timing of dividend
               distributions, the fiscal year in which amounts are distributed
               may differ from the year that the income or realized gains
               (losses) were recorded by the funds.
 
               On the statements of assets and liabilities, as a result of
               permanent book-to-tax differences, reclassification adjustments
               have been made as follows:

               stock distributions are recorded as of the close of business on
               the ex-dividend date and preferred stock dividends are accrued
               daily. Per share common stock distributions of $0.0509 and
               $0.0492 for Minnesota Municipal Term Trust Inc. and Minnesota
               Municipal Term Trust Inc. II, respectively, were declared in
               December and are payable in January. Net realized gains
               distributions, if any, will be made at least annually.
               Distributions are payable in cash or, for common shareholders
               pursuant to the funds' dividend reinvestment plans, reinvested in
               additional shares of the funds' common stock. Under the plans,
               common shares will be purchased in the open market.
 
                  USE OF ESTIMATES

               generally accepted accounting principles requires management to

               The funds have entered into the following agreements with Piper
               Capital Management Incorporated (the advisor and administrator):
 
               The investment advisory agreement provides the advisor with a
               monthly investment management fee in an amount equal to an
               annualized rate of 0.25% of the funds' average weekly net assets
               (computed by subtracting liabilities, which exclude preferred
               stock, from the value of the total assets of the funds). For its
               fee, the advisor provides investment advice and, in general,
               conducts the management and investment activity of the funds.

               The administration agreement provides the administrator with a
               monthly fee in an amount equal to an annualized rate of 0.15% of
               the funds' average weekly net assets (computed by subtracting
               liabilities, which exclude preferred stock, from the value of the
               total assets of the funds). For its fee, the administrator will
               provide regulatory reporting and record-keeping services for the
               funds.
 
                  REMARKETING AGENT FEE
               The funds have entered into a remarketing agent agreement with
               Merrill Lynch, Pierce, Fenner & Smith (the remarketing agent).
               The remarketing agreement provides the remarketing agent with a
               monthly fee in an amount equal to an annualized rate of 0.25% of
               the funds' average amount of RP outstanding. For its fee, the
               remarketing agent will remarket shares of RP tendered to it, on
               behalf of shareholders thereof, and will determine the applicable
               dividend rate for each seven-day dividend period.
 
                  OTHER FEES AND EXPENSES
               In addition to the investment management, administrative and the
               remarketing agent fees, the funds are responsible for paying most
               other operating expenses including: outside directors' fees and
               expenses; custodian fees; registration fees; printing and
               shareholder reports; transfer agent fees and expenses; legal,
               auditing and accounting services; insurance; interest; taxes and
               other miscellaneous expenses.
 
               Expenses paid indirectly represent a reduction of custodian fees
               for earnings on miscellaneous cash balances maintained by the
               funds.
 
(6) PENDING
    ACQUISITION
 ................................
               On December 15, 1997, Piper Jaffray Companies, Inc., the parent
               company of the funds' investment advisor, announced that it had
               entered into an agreement to be acquired by U.S. Bancorp. It is
               anticipated that this acquisition will be completed in the second
               quarter of 1998, subject to regulatory approval, the approval of
               Piper Jaffray Companies shareholders and the satisfaction of

               U.S. Bancorp is a multi-state bank holding company headquartered
               in Minneapolis, Minnesota with a geographic service area spanning
               17 states. As of December 31, 1997, U.S. Bancorp was the 15th
               largest U.S. commercial bank holding company, with assets of
               nearly $71.3 billion. U.S. Bank National Association ("U.S.
               Bank"), a wholly owned subsidiary of U.S. Bancorp, currently acts
               as the investment advisor to 32 mutual funds (the "First American
               Funds"). As of December 31, 1997, U.S. Bank, acting through its
               First American Asset Management group, managed more than $55
               billion in assets, including approximately $20.5 billion in
               assets of the First American Funds.
 
               Under the Investment Company Act of 1940, as amended (the "1940
               Act"), consummation of the acquisition of Piper Jaffray Companies
               by U.S. Bancorp will result in the assignment and automatic
               termination of the funds' investment advisory agreement with
               Piper Capital Management Incorporated. The 1940 Act requires that
               any new investment advisory agreement for the funds be approved
               by the funds' boards of directors and shareholders.

Independent Auditors' Report

THE BOARD OF DIRECTORS AND SHAREHOLDERS
MINNESOTA MUNICIPAL TERM TRUST INC. AND
MINNESOTA MUNICIPAL TERM TRUST INC. II:
 
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of Minnesota Municipal Term Trust
Inc. and Minnesota Municipal Term Trust Inc. II as of December 31, 1997, 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 ended
December 31, 1997, and the financial highlights for each of the years in the
five-year period ended December 31, 1997. These financial statements and the
financial highlights are the responsibility of the funds' management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the 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. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased but not received, we request confirmations
from brokers and, where replies are not received, we carry out 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 the financial highlights referred
to above present fairly, in all material respects, the financial position of
Minnesota Municipal Term Trust Inc. and Minnesota Municipal Term Trust Inc. II
as of December 31, 1997, and the results of their operations, the changes in
their net assets and the financial highlights for the periods stated in the
first paragraph above, in conformity with generally accepted accounting

               is received at least 10 days before the record date for that
               distribution.
 
               If your shares are in certificate form, you may join the plan
               directly and have your distributions reinvested in additional
               shares of the fund. To enroll in this plan, call IFTC at
               1-800-543-1627. If your shares are registered in your brokerage
               firm's name or another name, ask the holder of your shares how
               you may participate.
 
               Banks, brokers or nominees, on behalf of their beneficial owners
               who wish to reinvest dividend and capital gains distributions,
               may participate in the plan by informing IFTC at least 10 days
               before each share's dividend and/or capital gains distribution.

                  PLAN ADMINISTRATION
               Beginning no more than five business days before the dividend
               payment date, IFTC will buy shares of the fund on the New York
               Stock Exchange (NYSE) or elsewhere on the open market.
 
               The fund will not issue any new shares in connection with the
               plan. All reinvestments will be at a market price plus a pro rata
               share of any brokerage commissions, which may be more or less
               than the fund's net asset value per share. The number of shares
               allocated to you is determined by dividing the amount of the
               dividend or distribution by the applicable price per share.
 
               There is no direct charge for reinvestment of dividends and
               capital gains, since IFTC fees are paid for by the fund. However,
               each participant pays a pro rata portion of the brokerage
               commissions. Brokerage charges are expected to be lower than
               those for individual transactions because shares are purchased
               for all participants in blocks. As long as you continue to
               participate in the plan, distributions paid on the shares in your
               account will be reinvested.
 
               IFTC maintains accounts for plan participants holding shares in
               certificate form and will furnish written confirmation of all
               transactions, including information you need for tax records.
               Reinvested shares in your account will be held by IFTC in
               noncertificated form in your name.
 
                  TAX INFORMATION
               Distributions invested in additional shares of the fund are
               subject to income tax, just as they would be if received in cash.
               Shareholders, as required by the Internal Revenue Service, will
               receive Form 1099 regarding the federal tax status of the prior
               year's distributions.
 
                  PLAN WITHDRAWAL
               If you hold your shares in certificate form, you may terminate
               your participation in the plan at any time by giving written
               notice to

               IFTC. If your shares are registered in your brokerage firm's
               name, you may terminate your participation via verbal or written
               instructions to your investment professional. Written
               instructions should include your name and address as they appear
               on the certificate or account.
 
               If notice is received at least 10 days before the record date,
               all future distributions will be paid directly to the shareholder
               of record.
 
               If your shares are issued in certificate form and you discontinue
               your participation in the plan, you (or your nominee) will
               receive an additional certificate for all full shares and a check
               for any fractional shares in your account.
 
                  PLAN AMENDMENT/TERMINATION
               The fund reserves the right to amend or terminate the plan.
               Should the plan be amended or terminated, participants will be
               notified in writing at least 90 days before the record date for
               such dividend or distribution. The plan may also be amended or
               terminated by IFTC with at least 90 days written notice to
               participants in the plan.
 
               Any question about the plan should be directed to your investment
               professional or to Investors Fiduciary Trust Company, P.O. Box
               419432, Kansas City, Missouri 64141, 1-800-543-1627.

                   GLOSSARY OF TERMS
- -------------------------------------------------------------------------------

                   ADVANCE REFUNDING
                   The sale of new bonds (a refunding issue) in 
                   advance, usually by some years, of the first call 
                   date of the old bonds (issue to be refunded). The 
                   refunding issue would normally have a lower rate 
                   than the issue to be refunded and the proceeds from 
                   the sale of the refunding issue would be invested, 
                   usually in government securities, until the 
                   higher-rate bonds become callable. 

                   COUPON
                   The interest rate on a bond that the issuer promises 
                   to pay to the holder until the bond matures or 
                   resets its rate. It is expressed as an annual 
                   percentage of face value.
                   
                   CREDIT RISK
                   The risk that a bond issuer will not make timely 
                   principal and interest payments and a loss to the 
                   investor will result.

                   INTEREST RATE RISK
                   The risk that after an investor purchases a bond, 
                   interest rates will rise and the price of the bond 
                   will go down.

                   PREFERRED STOCK
                   The preferred stock issued by MNA and MNB pays 
                   dividends at a specified rate and has preference 
                   over common stock in the payments of dividends and 
                   the liquidation of assets. Rates paid on preferred 
                   stock are reset every seven days and are based on 
                   short-term, tax-exempt interest rates. Preferred 
                   shareholders accept these short-term rates in 
                   exchange for low credit risk (shares of preferred 
                   stock are rated AAA by Moody's and S&P) and high 
                   liquidity (shares of preferred stock trade at par 
                   and are remarketed every seven days). The proceeds 
                   from the sale of preferred stock are invested at 
                   intermediate- and long-term tax-exempt rates. 
                   Because these intermediate- and long-term rates are 
                   normally higher than the short-term rates paid on 
                   preferred stock, common shareholders benefit by 
                   receiving higher dividends and/or an increase to the 
                   dividend reserve. However, the risk of having 
                   preferred stock is that if short-term rates rise 
                   higher than intermediate- and long-term rates, 
                   creating an inverted yield curve, common 
                   shareholders may receive a lower rate of return than 
                   if their fund did not have any preferred stock 
                   outstanding. This type of economic environment is 
                   unusual and historically has been short term in 
                   nature. Investors should also be aware that the 
                   issuance of preferred stock results in the 
                   leveraging of common stock, which increases the 
                   volatility of both the net asset value of the fund 
                   and the market value of shares of common stock.
     
                   REFUNDING DATE
                   The specific date when a bond is redeemed before 
                   maturity.
     
                   REALIZED GAINS
                   Profits earned by a fund from the sale of a security 
                   at a market price that is higher than its cost basis.
               
                   UNREALIZED APPRECIATION
                   A bond is said to be trading at unrealized gains 
                   when its current market price is higher than its 
                   cost basis.
