preserved.

Dear Shareholder

I would like to take this opportunity to discuss the performance of your Nuveen
Exchange-Traded Fund over the past six months. Over this period, your Fund
continued to provide a stable, tax-free dividend while seeking to enhance its
after-tax total return. Capital preservation also remained an integral part of
the portfolio manager's strategies. The combination of these factors
demonstrates that Nuveen's municipal bond funds can serve as excellent
investment options for income-oriented investors.

The Year in Review
The past 6 to 12 months saw the U.S. economy continue its pattern of
non-inflationary growth, accompanied by low interest rates and unemployment
levels that remain among the lowest in three decades. Much of the current
economic growth is propelled by consumer demand, which has helped the U.S.
resist the downward pull of weaker overseas markets. All indications point to a
confident American consumer who is comfortable with the current state of the
economy, especially the performance of the housing, stock, and job markets. This
confidence is reflected in the most recent Consumer Confidence Index report
issued by the Conference Board, which showed a record-setting seventh
consecutive month of gains in May. On the global front, the turmoil of the past
two years appears to be fading somewhat, as international financial markets have
begun to recover.

Inflation in the U.S. continued to operate at benign levels, with an increase of
2.2% for the 12 months ended April 30, 1999. Despite a spike in consumer prices
in April, which was propelled by rising energy costs (which have subsequently
declined), the general backdrop of inflation indicators continued to be mild,
with the employment cost index, average hourly earnings, and import and producer
price trends all remaining favorable. As Federal Reserve Chairman Alan Greenspan
recently stated, one of the key factors in achieving today's peaceful
coexistence of economic growth and low inflation has been increased
productivity. Improvements in productivity, spurred by technological advances,
have been responsible for offsetting wage and other inflationary pressures that
we would normally expect to see as part of a growing economy.

On the interest rate front, last fall saw the Federal Reserve ease short-term
rates for the first time in almost three years. Between the end of September and
mid-November 1998, three successive cuts brought the federal funds rate to
4.75%, averting a potential domestic credit crunch and restoring some stability
to global markets. Following the success of these preemptive moves, the Federal
Reserve indicated that fighting inflation continued to be a top priority by
remaining in a proactive mode and responding to April's increased consumer
prices with a shift to a tightening bias. By doing this, the Fed signaled its
contin ued support of the market without changing interest rates or
fundamentally altering the economy. In the months ahead, we will continue to
watch for indications from theFed and other factors that affect the economy's
future, including wage and employment statistics, reports on productivity
growth, capital equipment spending, and the progress of international economic
recovery. We believe these key components will influence the outlook for
fixed-income markets well into the new millennium.

Municipal Bonds:
An Attractive Investment Option
As interest rates declined over the past year, our municipal bond funds
continued to provide bright spots among the various invest-ment options,
generally offering attractive, stable income in a market that places a high
premium on yield. In 1998, municipal bonds represented a reasonably insulated
haven in an otherwise turbulent market, with lower volatility relative to
Treasury bonds and other fixed-income investments. In fact, for the first four
months of 1999, municipals continued to outperform Treasuries.
<PAGE>
The high ratio of tax-exempt municipal yields to Treasury yields shel tered
municipal bonds from the price decline that occurred in the Treasury market
during the first four months of the year. While the interest rate on 30-year
Treasury bonds rose from 5.10% at the end of December to 5.66% as of April 30,
1999, the yield on the Bond Buyer Revenue Bond Index, an unmanaged index of
long-term municipal revenue bonds, gained just three basis points - from 5.26%
to 5.29%. Given the inverse relationship between interest rates and bond prices,
Treasury bond prices fell as rates rose over this period. Though municipal bond
prices did decrease, the decline was not as dramatic as the drop in Treasuries.
The differential in performance reflects the fact that Treasuries had become
relatively expensive as the result of safe-haven buying during the international
economic crises of the past year.

Line chart of: The Bond Buyer Revenue Bond Index

As the financial turmoil subsided in the first quarter of 1999, however, foreign
investors returned to investing in their own countries rather than in U.S.
dollar-denominated securities. The combination of an increase in interest rates
and a decline in demand caused U.S. Treasuries to drop in price.

At the end of April 1999, the ratio between long-term municipal yields and
30-year Treasury yields stood at 94%, compared with the historical average of
86% for the period of 1986-1999. For investors, this meant that quality
long-term municipal bonds offered yields comparable to those of long Treasury
bonds even before the tax advantages of municipal bonds were taken into account.
On an after-tax basis in today's market, municipal bonds continue to present an
exceptionally attractive investment option relative to Treasuries.

During 1998, lower interest rates and the strong economy combined to generate
high levels of new municipal issuance and a significant increase in the
refinancing of existing bonds. Municipal issuance in 1998 reached $284 billion,
up 29% over 1997. In terms of total municipal issuance, 1998 ranked as the
second largest year on record, next to 1993's $292 billion. In the first four
months of 1999, however, as the market settled into a more stable interest rate
environment, refunding activity dropped off dramatically. As a result, municipal
supply in 1999 has declined by approximately 25% from the levels of a year ago.
This, in turn, has enhanced the attractiveness of the munic ipal bonds that were
brought to market, as demand - especially from individual investorsremained
relatively strong.

The Value of Nuveen Expertise
The solid track record of a proven investment manager is one key to taking
advantage of the attractive values currently available in the municipal market.
The near-record level of municipal issuance in 1998, for example, highlighted
the value of Nuveen's in-depth knowledge of the municipal market, as our
portfolio management teams carefully analyzed each issue to select those
securities best suited to help the Funds achieve their investment objectives.
With the outlook for tighter supply and continued demand in 1999, Nuveen's
established market position ensures that we will have exceptional access to the
bond offerings that have the potential to add value for our shareholders.

As a further enhancement to our management capabilities, Nuveen has assembled a
strong group of investment managers - experts in their particular areas of the
market - to provide investors with the advantage of their experience and
insights. In addition to Nuveen Advisory Services for tax-free investing, you
and your financial adviser can rely on Institutional Capital Corporation for
value-oriented equity investing and Rittenhouse Financial Services, Inc. for
growth-oriented equity investing. We encourage you to talk with your financial
adviser about Nuveen's expanding array of investments and the ways that Nuveen
Funds can help you establish a diversified portfolio designed to build and
sustain long-term financial security. For more information on our funds, contact
your adviser for a prospectus, or call Nuveen at (800) 621-7227. Please read it
carefully before you invest or send money.

Nuveen Exchange-Traded Funds
Portfolio Manager's Comments

Portfolio manager Steve Krupa discusses the municipal market environment,
fund performance, and the outlook for the Nuveen national insured
exchange-traded funds. Steve, who has served as portfolio manager for Insured
Quality and Insured Opportunity since their inceptions, assumed management
responsibilities for the Premier Insured Income Fund and the Insured Premium
Income Fund 2 on July 1, 1998, as part of Nuveen's efforts to maximize the
efficient use of staff resources and portfolio manager expertise. Steve is a
20-year veteran of Nuveen with more than 20 years of investment experience.

What factors have influenced the municipal market during the past 12 months?
Over the past 12 months, the U.S. economy continued to enjoy strong
non-inflationary growth, low interest rates, and low unemployment. With tax
revenues rising along with the growth in personal income, the national
government is generating a budget surplus, putting an end to 28 straight years
of federal budget deficits (1970-97). Over the past year, the
municipal-to-Treasury ratio ranged as high as 104%, offering investors in
quality long-term municipal bonds yields comparable to those of Treasury bonds,
even before the tax advantage of municipals was taken into account.

The other major story in the municipal market over the past 12 months was 1998
calendar year's impressive supply of new issuance. In the fourth quarter of
1998, investors saw $25-30 billion in new bonds brought to market each month.
Demand for municipal bonds also remained high, due to cash flow from
non-traditional investors as well as from the traditional buyers of mutual and
exchange-traded funds, such as individual investors and insurance companies. In
the first four months of 1999, however, there was a 25% drop-off in new issue
volume from 1998 levels. During this period, the continued demand from
individual investors compensated for lower demand from insurance companies,
which currently have fewer assets to invest due to heavy insurance premium price
competition and mounting claims from a series of devastating spring storms in
the Midwest and South.

For the remainder of 1999, the municipal market will be heavily influenced by
the direction of interest rates and inflation. If interest rates remain stable
or increase, we expect to see lower refinancing volume and a continuation of the
tighter supply scenario of the past four months. Demand should remain strong, as
individual investors look to diversify their portfolios by reallocating profits
from the equity market into fixed-income investments. These reallocation efforts
will be expanded if the volatility in equities continues. Even with lower supply
and high demand, Nuveen's position in the municipal market ensures that we will
have access to the best offerings in the marketplace.

How did the Funds perform over the past year?
For the 12 months ended April 30, 1999, the Funds produced total returns on net
asset value (NAV) ranging from 6.60% to 7.71%, providing taxable-equivalent
total returns of 9.39% to 10.17%, as shown in the accompanying table. For
comparison purposes, the total return on the Funds' benchmark - the Lehman
Brothers Insured Municipal Bond Index - and the average for the Lipper Insured
Leveraged Municipal Debt category are also provided.

Over the past year, the yield on the Bond Buyer Revenue Bond Index, an unmanaged
index of long-term municipal revenue bonds, fell only 23 basis points, an
indication of a relatively stable interest rate climate. In this environment,
the Funds' durations (the measure of a bond fund's price volatility in response
to interest rate changes) played a smaller, though still significant role in
determining their returns relative to the market, as measured by the Lehman
insured index. NPX, which had the longest leverage-adjusted duration (10.52)
among these funds as of April 30, 1999, also had the best performance over the
past 12 months. In comparison, the duration of the unleveraged Lehman index was
8.42. Factors such as sector weightings and levels of call protection also had
an impact on the performance of each Fund.

How were the Funds' dividends and share prices affected?
Good call protection helped support the dividends of NQI, NIO, and NPX and
shield the income of these Funds from erosion. As of April 30, 1999, NPX had
provided 30 consecutive months of steady or increasing income, while NQI and NIO
had each provided shareholders with steady dividends for 12 straight months.
During the past year, lower interest rates led to an increased number of bond
calls, as issuers sought to reduce debt financing costs. In addition, declining
rates meant that proceeds from prepaid or matured bonds had to be reinvested in
issues paying relatively lower current rates. Both of these situations
contributed to a reduction in the income level of NIF and necessitated a
dividend cut in July 1998. Current market conditions indicate that NIF's
dividend should remain sustainable at its present level for the foreseeable
future. All of the Funds have continued to provide attractive market yields.

As interest rates declined, active demand for the national insured
exchange-traded funds resulted in solid share price performance. At the same
time, gains in the Funds' NAVs reflected gains in the overall bond market. As a
result of these factors, NIO saw its premium (share price over NAV) widen over
the past year, while the discount (share price below NAV) on NPX narrowed, and
both NQI and NIF moved from discounts to premiums.

What key strategies were used to manage the Funds during the past year?
Over the past year, the Funds offered the benefit of insulation from the
volatility experienced by other markets, enhanced by dependable tax-free income.
The focus of our management strategies for these Funds contin ued to be on
supporting the highest level of tax-exempt dividends consistent with capital
preservation.

During the 12 months ended April 1999, several sectors offered opportunities to
add value and enhance the Funds' call protection and portfolio structure. These
included the utilities sector, where deregulation and abundant new supply -
boosted by the record-setting $7 billion Long Island Power Authority offering -
provided increased opportunities to find the types of bonds that can help us
achieve our goals for these Funds. We also found opportunities in bonds issued
by the healthcare sector, specifically hospitals, which continue to undergo
pressure from health management systems and the federal government. In
transportation, the ongoing demand for larger facilities resulted in a good
supply of airport bonds, including those issued by O'Hare International and
Midway airports in Chicago. The continued growth of this industry makes airport
bonds one of our favorite groups. As interest rates trended lower during the
fourth quarter of 1998, several issuers took the opportunity to advance refund
bonds, and all of these Funds benefited from the price appreciation that
resulted from this event.

In the area of call protection, NQI and NIO continue to offer good levels of
protection over the next two years, as less than 9% of each portfolio is subject
to calls before 2001. With virtually no scheduled bond calls until 2002, both
NIF and NPX currently offer outstanding call protection, which should provide
additional stability for their dividends over this period. Beginning in 2002,
however, these Funds will enter the normal part of the bond cycle in which bond
calls are more likely to occur. To minimize the impact of future bond calls, we
are already at work on strategies for managing through the upcoming period. One
such strategy involves selling callable bonds before their scheduled call dates
and reinvesting the proceeds at the long end of the yield curve to take
advantage of current yields. Nuveen's excellent surveillance and research help
us properly evaluate each issue so that we can find and maximize selling and
reinvestment opportunities. These buy/sell deci sions can benefit the Funds by
adding asset value and increasing the potential for earning income.

What is Nuveen's outlook for the Funds' future?
Looking ahead for the Nuveen national insured funds, our focus will continue to
be on supporting the income streams of these Funds. Our strategies will include
repositioning assets by investing in bonds found on the long end of the yield
curve to move the Funds' durations to a more market-neutral position and boost
both income and total return potential. We will also continue to reinvest any
bond call proceeds in the most advantageous manner possible. The success ful
execution of these strategies demonstrates the value that can be added by an
active bond manager such as Nuveen. As an experienced investment manager
knowledgeable about the unique aspects of the municipal market, we are in the
marketplace every day, monitoring market dynamics, looking for opportunities,
and capitalizing on them to the benefit of shareholders.

In our opinion, municipal bonds are currently one of the most compelling values
in the investment marketplace. Over the past 12 months, the value of these
quality investments has been enhanced by excellent municipal-to-Treasury ratios
as well as a market environment characterized by low interest rates and benign
inflation. With continued volatility in the equity markets and investors'
increasing awareness of the need for asset allocation rebalancing, the demand
for municipal bond funds is expected to grow. We believe that investors who take
advantage of current opportunities in the municipal market should be rewarded
with healthy returns and attractive yields in the months ahead.

Notes to Financial Statements
(Unaudited)

1. General Information and Significant Accounting Policies
The National Funds (the "Funds") covered in this report and their corresponding
New York Stock Exchange symbols are Nuveen Insured Quality Municipal Fund, Inc.
(NQI), Nuveen Insured Municipal Opportunity Fund, Inc. (NIO), Nuveen Premier
Insured Municipal Income Fund, Inc. (NIF) and Nuveen Insured Premium Income
Municipal Fund 2 (NPX).

Each Fund invests primarily in a diversified portfolio of municipal obligations
issued by state and local government authorities. The Funds are registered under
the Investment Company Act of 1940 as closed-end, diversified management
investment companies.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with
generally accepted accounting principles.

Securities Valuation
The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Directors/Trustees. When
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service establishes fair market value based on yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, indications of value from securities dealers and general
market conditions. Temporary investments in securities that have variable rate
and demand features qualifying them as short-term securities are valued at
amortized cost, which approximates market value.

Securities Transactions
Securities transactions are recorded on a trade date basis. Realized gains and
losses from such transactions are determined on the specific identification
method. Securities purchased or sold on a when-issued or delayed delivery basis
may have extended settlement periods. The securities so purchased are subject to
market fluctuation during this period. The Funds have instructed the custodian
to segregate assets in a separate account with a current value at least equal to
the amount of the when-issued and delayed delivery purchase commitments. At
April 30, 1999, Insured Quality and Insured Premium Income 2 had outstanding
delayed delivery and when-issued purchase commitments of $5,387,502 and
$7,860,949, respectively. There were no such outstanding purchase commitments in
either Insured Opportunity or Premier Insured Income.

Investment Income
Interest income is determined on the basis of interest accrued, adjusted for
amortization of premiums and accretion of discounts on long-term debt securities
when required for federal income tax purposes.

Federal Income Taxes
Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to comply with the requirements of the Internal Revenue Code applicable
to regulated investment companies and to distribute all of its tax-exempt net
investment income, in addition to any significant amounts of net realized
capital gains and/or market discount realized from investment transactions. The
Funds currently consider significant net realized capital gains and/or market
discount as amounts in excess of $.01 per Common share. Furthermore, each Fund
intends to satisfy conditions which will enable interest from municipal
securities, which is exempt from regular federal income tax, to retain such
tax-exempt status when distributed to shareholders of the Funds. Net realized
capital gain and market discount distributions are subject to federal taxation.

Dividends and Distributions to Shareholders
Tax-exempt net investment income is declared monthly as a dividend and payment
is made or reinvestment is credited to shareholder accounts on the first
business day after month-end. Net realized capital gains and/or market discount
from investment transactions, if any, are distributed to shareholders not less
frequently than annually. Furthermore, capital gains are distributed only to the
extent they exceed available capital loss carryforwards.

Distributions to shareholders of tax-exempt net investment income, net realized
capital gains and/or market discount are recorded on the ex-dividend date. The
amount and timing of distributions are determined in accordance with federal
income tax regulations, which may differ from generally accepted accounting
principles. Accordingly, temporary over-distributions as a result of these
differences may occur and will be classified as either distributions in excess
of net investment income, distributions in excess of net realized gains and/or
distributions in excess of net ordinary taxable income from investment
transactions, where applicable.
<PAGE>
Preferred Shares
The Funds have issued and outstanding $25,000 stated value Preferred shares.
Each Fund's Preferred shares are issued in more than one Series. The dividend
rate on each Series may change every seven days, as set by the auction agent.
The number of Preferred shares outstanding, by Series and in total, at April 30,
1999, is as follows:

                                                          Premier      Insured

==============================================================================

*Effective April 30, 1999, Insured Opportunity issued 3,200 Series W2 $25,000
 stated value Preferred shares.

 Effective May 7, 1999, Insured Quality issued 2,320 Series Th $25,000 stated
 value Preferred shares.

 Effective June 18, 1999, Premier Insured issued 840 Series W $25,000 stated
 value Preferred shares.


Insurance
The Funds invest in municipal securities which are either covered by insurance
or are backed by an escrow or trust account containing sufficient U.S.
government or U.S. government agency securities, both of which ensure the timely
payment of principal and interest. Each insured municipal security is covered by
Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance.
Such insurance does not guarantee the market value of the municipal securities
or the value of the Funds' shares. Original Issue Insurance and Secondary Market
Insurance remain in effect as long as the municipal securities covered thereby
remain outstanding and the insurer remains in business, regardless of whether
the Funds ultimately dispose of such municipal securities. Consequently, the
market value of the municipal securities covered by Original Issue Insurance or
Secondary Market Insurance may reflect value attributable to the insurance.
Portfolio Insurance is effective only while the municipal securities are held by
the Funds. Accordingly, neither the prices used in determining the market value
of the underlying municipal securities nor the net asset value of the Funds'
shares include value, if any, attributable to the Portfolio Insurance. Each
policy of the Portfolio Insurance does, however, give the Funds the right to
obtain permanent insurance with respect to the municipal security covered by the
Portfolio Insurance policy at the time of its sale.

Derivative Financial Instruments
The Funds may invest in certain derivative financial instruments including
futures, forward, swap and option contracts, and other financial instruments
with similar characteristics. Although the Funds are authorized to invest in
such financial instruments, and may do so in the future, they did not make any
such investments during the six months ended April 30, 1999.

Use of Estimates
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 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 may differ
from those estimates.

6. Management Fee and Other Transactions with Affiliates
Under the Funds' investment management agreements with Nuveen Advisory Corp.
(the "Adviser"), a wholly owned subsidiary of The John Nuveen Company, each Fund
pays an annual management fee, payable monthly, at the rates set forth below,
which are based upon the average daily net asset value of each Fund:

Average Daily Net Asset Value                                    Management Fee
- -------------------------------------------------------------------------------
For the first $125 million                                          .6500 of 1%
For the next $125 million                                           .6375 of 1

The fee compensates the Adviser for overall investment advisory and
administrative services and general office facilities. The Funds pay no
compensation directly to those of its Directors/Trustees who are affiliated with
the Adviser or to their officers, all of whom receive remuneration for their
services to the Funds from the Adviser.

All of the long-term and intermediate-term investments owned by the Funds are
either covered by insurance issued by several private insurers or are backed by
an escrow or trust containing U.S. government or U.S. government agency
securities, both of which ensure the timely payment of principal and interest in
the event of default. Such insurance or escrow, however, does not guarantee the
market value of the municipal securities or the value of the Funds' shares.

For additional information regarding each investment security, refer to the
Portfolio of Investments of each Fund.

Year 2000
The concern that computer systems may have problems processing date-related
information in the year 2000 and beyond has challenged businesses and
organizations to thoroughly review all aspects of their operations. We have
undertaken just such an approach at Nuveen in preparation for the millennium.
Over the last 10 years, we have updated or replaced our trading, fund
management, and pricing systems at Nuveen - systems that directly affect our
investors and their financial advisers - to address Year 2000 concerns.

We continue to work closely with our transfer agent, custodian, firms through
whom we buy and sell portfolio securities, and other service partners to monitor
the Year 2000 readiness of their systems, while addressing other remaining
systems issues.

In addition, the Funds hold securities of issuers whose business operations
leave them susceptible to Year 2000 concerns. We seek to evaluate an issuer's
Year 2000 readiness as part of our initial and ongoing research of these
issuers. This is only one of the many factors considered in determining whether
to buy, sell, or continue holding a particular security.

We anticipate that all significant components of our Year 2000 review, repair,
and testing program will be complete by mid-1999. This includes appropriate
industry-wide testing of critical systems and receipt of satisfactory assurances
from critical service providers, vendors, and issuers regarding their Year 2000
readiness. We are also making Year 2000 contingency plans to guide recovery
efforts in the event that, despite our remediation attempts, Year 2000 issues
adversely affect the Funds. Although we cannot give complete assurance at this
time that the steps we take will be sufficient to prevent any problems that
would impact the Nuveen Exchange-Traded Funds, we can assure you that we will
take all reasonable steps to prevent disruption of the services provided by your
Fund.



Each fund intends to repurchase shares of its own common or preferred stock in
the future at such times and in such amounts as is deemed advisable. No shares
were repurchased during the six-month period ended April 30, 1999. Any future
repurchases will be reported to shareholders in the next annual or semiannual
report.
