                                      Notes

1. Significant Accounting Policies

The following accounting policies are in accordance with U.S. generally accepted
  accounting principles and are consistently followed by Delaware Investments
             Minnesota Municipal Income Fund II, Inc. (the "Fund").

Security Valuation - Long-term debt securities are valued by an independent
pricing service and such prices are believed to reflect the fair value of such
securities. Short-term debt securities having less than 60 days to maturity are
valued at amortized cost, which approximates market value. Other securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith under the direction of the Fund's Board of
Directors. In determining whether market quotations are readily available or
fair valuation will be used, various factors will be taken into consideration,
such as market closures, aftermarket trading or significant events after local
market trading (e.g., government actions or pronouncements, trading volume or
volatility on markets, exchanges among dealers, or news events).

Federal Income Taxes - The Fund intends to continue to qualify for federal
income tax purposes as a regulated investment company and make the requisite
distributions to shareholders. Accordingly, no provision for federal income
taxes has been made in the financial statements.

Use of Estimates - 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 at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

Other - Expenses common to all funds within the Delaware Investments(R) Family
of Funds are allocated amongst the funds on the basis of average net assets.
Management fees and some other expenses are paid monthly. Security transactions
are recorded on the date the securities are purchased or sold (trade date) for
financial reporting purposes. Costs used in calculating realized gains and
losses on the sale of investment securities are those of the specific securities
sold. Interest income is recorded on the accrual basis.




Discounts and premiums are amortized to interest income over the lives of the
respective securities. The Fund declares and pays dividends from net investment
income monthly and distributions from net realized gain on investments, if any,
annually.

In addition, in order to satisfy certain distribution requirements of the Tax
Reform Act of 1986, the Fund may declare special year-end dividend and capital
gains distributions during November or December to shareholders of record on a
date in such month. Such distributions, if received by shareholders by January
31, are deemed to have been paid by the Fund and received by shareholders on the
earlier of the date paid or December 31 of the prior year.

2. Investments

At June 30, 2006, the cost of investments for federal income tax purposes has
 been estimated since the final tax characteristics cannot be determined until
   fiscal year end. At June 30, 2006, the cost of investments and unrealized
           appreciation (depreciation) for the Fund were as follows:

Cost of investments                      $248,712,109
                                         ____________

Aggregate unrealized appreciation           8,538,289

Aggregate unrealized depreciation          (1,555,393)
                                         ____________

Net unrealized appreciation              $  6,982,896
                                         ____________

For federal income tax purposes, at March 31, 2006, capital loss carryforwards
of $533,589 may be carried forward and applied against future capital gains.
Such capital loss carryforwards expire as follows: $339,543 expires in 2008,
$175,804 expires in 2009, $8,416 expires 2010 and $9,826 expires in 2013.


3. Credit and Market Risk

The Fund uses leverage in the form of preferred shares. Leveraging may result in
a higher degree of volatility because the Fund's net asset value could be more
sensitive to fluctuations in short-term interest rates and changes in market
value of portfolio securities attributable to the leverage.

The Fund concentrates its investments in securities issued by municipalities.
The value of these investments may be adversely affected by new legislation
within the state, regional or local economic conditions, and differing levels of
supply and demand for municipal bonds. Many municipalities insure repayment for
their obligations. Although bond insurance reduces the risk of loss due to
default by an issuer, such bonds remain subject to the risk that market value
may fluctuate for other reasons and there is no assurance that the insurance
company will meet its obligations. These securities have been identified in the
Schedule of Investments.

The Fund may invest in inverse floating rate securities ("inverse floaters"), a
type of derivative tax-exempt obligation with floating or variable interest
rates that move in the opposite direction of short-term interest rates, usually
at an accelerated speed. Consequently, the market values of inverse floaters
will generally be more volatile than other tax-exempt investments. Such
securities are identified on the Schedule of Investments.

The Fund may invest in advanced refunded bonds, escrow secured bonds or defeased
bonds. Under current federal tax laws and regulations, state and local
government borrowers are permitted to refinance outstanding bonds by issuing new
bonds. The issuer refinances the outstanding debt to either reduce interest
costs or to remove or alter restrictive covenants imposed by the bonds being
refinanced. A refunding transaction where the municipal securities are being
refunded within 90 days from the issuance of the refunding issue is known as a
"current refunding". "Advance refunded bonds" are bonds in which the refunded
bond issue remains outstanding for more than 90 days following the issuance of
the refunding issue. In an advance refunding, the issuer will use the proceeds
of a new bond issue to purchase high grade interest bearing debt securities
which are then deposited in an irrevocable escrow account held by an escrow
agent to secure all future payments of principal and interest and bond premium
of the advance refunded bond. Bonds are "escrowed to maturity" when the proceeds
of the refunding issue are deposited in an escrow account for investment
sufficient to pay all of the principal and interest on the original interest
payment and maturity dates. Bonds are considered "pre-refunded" when the
refunding issue's proceeds are escrowed only until a permitted call date or
dates on the refunded issue with the refunded issue being redeemed at the time,
including any required premium. Bonds become "defeased" when the rights and
interests of the bondholders and of their lien on the pledged revenues or other
security under the terms of the bond contract are substituted with an
alternative source of revenues (the escrow securities) sufficient to meet
payments of principal and interest to maturity or to the first call dates.
Escrowed secured bonds will often receive a rating of AAA from Moody's Investors
Service, Inc., Standard & Poor's Ratings Group, and/or Fitch Ratings due to the
strong credit quality of the escrow securities and the irrevocable nature of the
escrow deposit agreement.

The Fund may invest up to 15% of its total assets in illiquid securities, which
may include securities with contractual restrictions on resale, securities
exempt from registration under Rule 144A of the Securities Act of 1933, as
amended, and other securities which may not be readily marketable. The relative
illiquidity of these securities may impair the Fund from disposing of them in a
timely manner and at a fair price when it is necessary or desirable to do so.
While maintaining oversight, the Fund's Board of Directors has delegated to
Delaware Management Company the day-to-day functions of determining whether
individual securities are liquid for purposes of the Fund's limitation on
investments in illiquid assets. At June 30, 2006, there were no Rule 144A
securities and no securities have been determined to be illiquid under the
Fund's Liquidity Procedures.
