                  CAUTION REGARDING FORWARD-LOOKING STATEMENTS

This report contains certain forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended. Forward-looking
statements include statements regarding the goals, beliefs, plans or current
expectations of First Trust Advisors L.P. ("First Trust" or the "Advisor")
and/or Stonebridge Advisors LLC ("Stonebridge" or the "Sub-Advisor") and their
respective representatives, taking into account the information currently
available to them. Forward-looking statements include all statements that do not
relate solely to current or historical fact. For example, forward-looking
statements include the use of words such as "anticipate," "estimate," "intend,"
"expect," "believe," "plan," "may," "should," "would" or other words that convey
uncertainty of future events or outcomes.

Forward-looking statements involve known and unknown risks, uncertainties and
other factors that may cause the actual results, performance or achievements of
First Trust Tax-Advantaged Preferred Income Fund (the "Fund") to be materially
different from any future results, performance or achievements expressed or
implied by the forward-looking statements. When evaluating the information
included in this report, you are cautioned not to place undue reliance on these
forward-looking statements, which reflect the judgment of the Advisor and/or
Stonebridge and their respective representatives only as of the date hereof. We
undertake no obligation to publicly revise or update these forward-looking
statements to reflect events and circumstances that arise after the date hereof.

                         PERFORMANCE AND RISK DISCLOSURE

There is no assurance that the Fund will achieve its investment objectives. The
Fund is subject to market risk, which is the possibility that the market values
of securities owned by the Fund will decline and that the value of the Fund
shares may therefore be less than what you paid for them. Accordingly, you can
lose money investing in the Fund. See "Risk Considerations" in the Notes to
Financial Statements for a discussion of other risks of investing in the Fund.

Performance data quoted represents past performance, which is no guarantee of
future results, and current performance may be lower or higher than the figures
shown. For the most recent month-end performance figures, please visit
http://www.ftportfolios.com or speak with your financial advisor. Investment
returns, net asset value and common share price will fluctuate and Fund shares
may be worth more or less than their original cost.

                             HOW TO READ THIS REPORT

This report contains information that may help you evaluate your investment. It
includes details about the Fund and presents data and analysis that provide
insight into the Fund's performance and investment approach.

By reading the portfolio commentary by the portfolio management team at the
Fund's Sub-Advisor, you may obtain an understanding of how the market
environment affected the Fund's performance. The statistical information that
follows may help you understand the Fund's performance compared to that of

FIRST TRUST TAX-ADVANTAGED PREFERRED INCOME FUND

The primary investment objective of First Trust Tax-Advantaged Preferred Income
Fund ("FPI" or the "Fund") is to seek current income. As a secondary objective,
the Fund seeks capital preservation. The Fund pursues its objectives by
investing primarily in preferred securities that the Sub-Advisor believes at the
time of investment are eligible to pay dividends that qualify for certain
favorable federal income tax treatment as "tax-advantaged" when received by
shareholders of the Fund. There is no assurance that the Fund's objectives will
be achieved. The Fund may not be appropriate for all investors.

MARKET RECAP

The current credit crisis continues to persist and has caused the economy to
slow significantly over the past six months. Adverse trends that surfaced toward
the middle of 2007 have continued into 2008 and created new problems related to
financial institutions in particular. Write downs worldwide are approaching $350
billion and some analysts believe there could be a long way to go before we get
to the other side of this quandary. Financial companies are raising capital at
an unprecedented rate to offset the write downs. Much of the capital raised has
been in the form of preferred securities, which qualify as tier 1 capital for
banks and equity capital for other financial institutions. Although this is good
news for preferred investors over the longer-term, the size of the new issues
has forced issuers to pay a premium to the secondary market, thus having the
impact of creating a heavy weight over the preferred securities market in the
short-term. Once the markets work through the credit crisis and stabilize, we
expect to see preferred securities rally relative to Treasury and some other
fixed-income alternatives.

PERFORMANCE ANALYSIS

FPI had an especially difficult six-month period as the total return on net
asset value ("NAV") for the six months ended April 30 was -20.26% and the total
return on market price was -14.02%. This compares rather unfavorably to our
blended benchmark return of -9.69% (see table below) for the same six-month
period. The primary driver for this underperformance was Irwin Financial
Corporation, which announced a temporary suspension of its dividend in March,
thus triggering a price reduction of over 70%.



INDEX/WEIGHTING                                                   6 MONTH TOTAL RETURN
- ---------------                                                   --------------------
                                                               
Merrill Lynch Preferred DRD Index (50%)                                 -8.64%
Merrill Lynch Preferred Adjustable Rate Index (27%)                    -20.03%
Merrill Lynch Preferred American Depository Shares Index (15%)           0.00%
Scotia Capital Income Trust TR Index (8%)                                0.55%


As we mentioned in the Fund's annual report, a majority of the preferred
securities market is comprised of financial issuers, which have been at the root
of the credit crisis. FPI invests at least 25% of its portfolio in banks and 50%
in financials, thus causing further underperformance beyond Irwin because our
blended benchmark has a lower exposure to financials.

Offsetting the Fund's losses on some of the financial securities was the Fund's
exposure in energy and utilities securities, which had a positive return over
the period.

MARKET AND FUND OUTLOOK

We believe that the remainder of 2008 will be marked by further credit
deterioration in residential mortgages, consumer credit (home equity and credit
cards), commercial real estate and construction loan portfolios as the economy
further weakens. This will likely cause the preferred securities market to
experience continued volatility for the next quarter or two, with the most
pressure on names with weakened capital positions and negative headline risk.

                        PORTFOLIO COMMENTARY (CONTINUED)

Two issuers of securities held by the Fund suspended their quarterly dividends
in the last quarter, resulting in a reduction in the Fund's June dividend to
Common Shareholders. On Friday, June 6, 2008, Heartland Financial ("Heartland"),
suspended quarterly dividends on its preferred securities held by the Fund. On
June 6, 2008, the Fund held a total of $6,000,000 aggregate par value of Series
B Fixed-Rate Non-Cumulative Redeemable Perpetual Preferred Shares ("Heartland
Preferred Shares"). Such action by Heartland resulted in a reduction in the
price of the Heartland Preferred Shares, which led to a significant decline in
the Fund's NAV. Primarily as a result of such event, the Fund's NAV declined
from $13.07 as of Thursday, June 5, 2008, to $11.54 as of Friday, June 6, 2008,
at 4:00 p.m. Eastern time, an approximate 11.7% reduction. On May 12, 2008,
IndyMac Bancorp, Inc. suspended quarterly dividends on its preferred securities
held by the Fund. On May 12, 2008, the Fund held a total of $5,000,000 aggregate
par value of Fixed-Rate Preferred Shares of IndyMac Bancorp, Inc.

Our strategy is to seek to diversify the Fund's portfolio with the goal of
upgrading the average credit ratings over time. As markets stabilize, we are
hopeful of a rebound in preferred securities and a reinstatement of dividends by
Irwin, IndyMac and Heartland as they return to profitability.

NOTES TO FINANCIAL STATEMENTS

                FIRST TRUST TAX-ADVANTAGED PREFERRED INCOME FUND
                           APRIL 30, 2008 (UNAUDITED)

                               1. FUND DESCRIPTION

First Trust Tax-Advantaged Preferred Income Fund (the "Fund") is a diversified,
closed-end management investment company organized as a Massachusetts business
trust on March 9, 2006 and is registered with the Securities and Exchange
Commission ("SEC") under the Investment Company Act of 1940, as amended (the
"1940 Act"). The Fund trades under the ticker symbol FPI on the American Stock
Exchange ("AMEX").

The Fund's primary investment objective is to seek current income. The Fund
seeks capital preservation as a secondary objective. Under normal market
conditions, the Fund will invest at least 80% of it Managed Assets in preferred
securities that Stonebridge Advisors LLC ("Stonebridge" or the "Sub-Advisor")
believes at the time of investment are eligible to pay dividends that qualify
for certain favorable federal income tax treatment as "tax-advantaged" when
received by shareholders of the Fund. "Managed Assets" means the average daily
gross asset value of the Fund (including assets attributable to the Fund's
Preferred Shares, if any, and the Principal amount of borrowings) minus the sum
of the Fund's accrued and unpaid dividends on any outstanding Preferred Shares
and accrued liabilities (other than the principal amount of any borrowings
incurred). There can be no assurance that the Fund will achieve its investment
objectives. The Fund may not be appropriate for all investors.

                       2. SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
preparation of financial statements in accordance with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts and disclosures in
the financial statements. Actual results could differ from those estimates.

A. PORTFOLIO VALUATION:

The net asset value ("NAV") of the Common Shares of the Fund is determined daily
as of the close of regular trading on the New York Stock Exchange ("NYSE"),
normally 4:00 p.m. Eastern Time, on each day the NYSE is open for trading.
Domestic debt securities and foreign securities are priced using data reflecting
the earlier closing of the principal markets for those securities. The NAV per
Common Share is calculated by dividing the value of all assets of the Fund
(including accrued interest and dividends), less all liabilities (including
accrued expenses, dividends declared but unpaid and any borrowings of the Fund)
and the liquidation value of any outstanding Auction Preferred Shares, by the
total number of Common Shares outstanding.

The Fund's investments are valued daily at market value or, in the absence of
market value with respect to any portfolio securities, at fair value according
to procedures adopted by the Fund's Board of Trustees. Securities for which
market quotations are readily available are valued at market value, which is
currently determined using the last reported sale price or, if no sales are
reported (as in the case of some securities traded over-the-counter), the last
reported bid price, except that certain U.S. government securities are valued at
the mean between the last reported bid and asked prices. The Fund will value
mortgage-backed securities and other debt securities not traded in an organized
market on the basis of valuations provided by dealers or by an independent
pricing service, approved by the Fund's Board of Trustees, which uses
information with respect to transactions in such securities, quotations from
dealers, market transactions for comparable securities, various relationships
between securities and yield to maturity in determining value. Debt securities
having a remaining maturity of less than sixty days when purchased are valued at
amortized cost. In the event that market quotations are not readily available,
the pricing service does not provide a valuation for a particular asset, or the
valuations are deemed unreliable, First Trust Advisors L.P. ("First Trust") may
use a fair value method to value the Fund's securities and investments.
Additionally, if events occur after the close of the principal markets for
particular securities (e.g., domestic debt and foreign securities), but before
the Fund values its assets, that could materially effect NAV, First Trust may
use a fair value method to value the Fund's securities and investments. The use
of fair value pricing by the Fund is governed by valuation procedures adopted by
the Fund's Board of Trustees and in accordance with the provisions of the 1940
Act.

Futures contracts, as explained below, are valued daily, and the Fund's net
equity therein, representing unrealized gain or loss on the contracts as
measured by the difference between the forward foreign exchange rates at the
reporting date, is included in the Statement of Assets and Liabilities.

B. FUTURES CONTRACTS:

Upon entering into a futures contract, the Fund is required to deposit with the
broker an amount of cash or cash equivalents equal to a certain percentage of
the contract amount (known as an initial margin deposit). Subsequent payments
(known as variation margin) are made or received by the Fund each day, depending
on the daily fluctuation of the value of the contract. The daily changes in
contract value are recorded as unrealized gains or losses, and the Fund
recognizes a realized gain or loss when the contract is closed. Should

market conditions change unexpectedly, the Fund may not achieve the anticipated
benefits of the futures contracts and may realize a loss. The use of futures
transactions involves the risk of imperfect correlation in movements in the
price of futures contracts, interest rates and the underlying hedged assets.

C. SECURITIES TRANSACTIONS AND INVESTMENT INCOME:

Securities transactions are recorded as of the trade date. Realized gains and
losses from securities transactions are recorded on the identified cost basis.
Dividend income is recorded on the ex-dividend date. Interest income is recorded
on the accrual basis. Amortization of premiums and accretion of discounts are
recorded using the effective interest method.

D. FOREIGN CURRENCY:

The books and records of the Fund are maintained in U.S. dollars. Foreign
currencies, investments and other assets and liabilities are translated into
U.S. dollars at the exchange rates prevailing at the end of the period.
Purchases and sales of investment securities and items of income and expense are
translated on the respective dates of such transactions. Unrealized gains and
losses which result from changes in foreign currency exchange rates have been
included in "Net change in unrealized appreciation (depreciation) on foreign
currencies" in the Statement of Operations. Net realized foreign currency gains
and losses include the effect of changes in exchange rates between trade date
and settlement date on investment security transactions, foreign currency
transactions and interest and dividends received. The portion of foreign
currency gains and losses related to fluctuations in exchange rates between the
initial purchase trade date and subsequent sale trade date is included in "Net
realized gain (loss) on foreign currencies" in the Statement of Operations.

E. RESTRICTED SECURITIES:

The Fund invests in restricted securities, which are securities that cannot be
offered for public sale without first being registered under the Securities Act
of 1933, as amended. Prior to registration, restricted securities may only be
resold in transactions exempt from registration. As of April 30, 2008, the Fund
held restricted securities as shown in the following table. The Fund does not
have the right to demand that such securities be registered. These securities
are valued according to the valuation procedures as stated in the Portfolio
Valuation footnote (Note 2A) and are not expressed as a discount to the carrying
value of comparable unrestricted securities.

F. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS:

The Fund will distribute to holders of its Common Shares quarterly dividends of
all or a portion of its net income after the payment of interest and dividends
in connection with leverage. Distributions will automatically be reinvested into
additional Common Shares pursuant to the Fund's Dividend Reinvestment Plan
unless cash distributions are elected by the shareholder.

Distributions from income and capital gains are determined in accordance with
income tax regulations, which may differ from accounting principles generally
accepted in the United States of America. These differences are primarily due to
differing treatments of income and gains on various investment securities held
by the Fund, timing differences and differing characterization of distributions
made by the Fund.

The tax character of distributions paid during the fiscal year ended October 31,
2007, was as follows:



                                 2007

                           APRIL 30, 2008 (UNAUDITED)

As of October 31, 2007, the components of distributable earnings on a tax basis
were as follows:


                                                 
Undistributed Ordinary Income ...........           $        --
Undistributed Long-Term Capital Gains ...           $        --
Net Unrealized Depreciation .............           $(3,646,407)


G. INCOME TAXES:

The Fund intends to continue to qualify as a regulated investment company by
complying with the requirements under Subchapter M of the Internal Revenue Code
of 1986, as amended, by distributing substantially all of its net investment
income and net realized gains to shareholders. Accordingly, no provision has
been made for federal or state income taxes.

In June 2006, Financial Accounting Standards Board Interpretation No. 48,
Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement
109 ("FIN 48"), was issued and is effective for fiscal years beginning after
December 15, 2006. This interpretation prescribes a minimum threshold for
financial statement recognition of the benefit of a tax position taken or
expected to be taken in a tax return. As of April 30, 2008, management has
evaluated the application of FIN 48 to the Fund, and has determined that there
is no material impact resulting from the adoption of this Interpretation on the
Fund's financial statements.

H. EXPENSES:

The Fund pays all expenses directly related to its operations.

I. ORGANIZATION AND OFFERING COSTS:

Organization costs consist of costs incurred to establish the Fund and legally
enable it to do business. These costs include filing fees, listing fees, legal
services pertaining to the organization of the business and audit fees relating
to the initial registration and auditing of the initial statement of assets and
liabilities, among other fees. Offering costs consist of legal fees pertaining
to the Fund's Common Shares offered for sale, registration fees, underwriting
fees, and printing of the initial prospectus, among other fees. First Trust and
Stonebridge have paid all organization expenses and all offering costs of the
Fund (other than sales load) that exceeded $0.04 per Common Share. The Fund's
share of Common Share offering costs, $118,610, was recorded as a reduction of
the proceeds from the sale of Common Shares during the fiscal period ended
October 31, 2006.

J. ACCOUNTING PRONOUNCEMENTS:

In September 2006, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 157, Fair Value Measurements ("FAS 157"),
effective for fiscal years beginning after November 15, 2007. FAS 157 defines
fair value, establishes a framework for measuring fair value and expands
disclosures about fair value measurements. Disclosure will include fair value
measurement at the reporting date and the assignment of levels within the
hierarchy in which the fair value measurements fall. At this time, management is
evaluating the implications of FAS 157 and its impact on the Fund's financial
statements, if any, has not been determined.

          3. INVESTMENT ADVISORY FEE AND OTHER AFFILIATED TRANSACTIONS

First Trust is a limited partnership with one limited partner, Grace Partners of
DuPage L.P., and one general partner, The Charger Corporation. First Trust
serves as investment advisor to the Fund pursuant to an Investment Management
Agreement. First Trust is responsible for the ongoing monitoring of the Fund's
investment portfolio, managing the Fund's business affairs and providing certain
administrative services necessary for the management of the Fund. For these
investment management services, First Trust is entitled to a monthly fee
calculated at an annual rate of 1.00% of the Fund's Managed Assets.

Stonebridge, an affiliate of First Trust, serves as the Fund's sub-advisor and
manages the Fund's portfolio subject to First Trust's supervision. The
Sub-Advisor receives a portfolio management fee at an annual rate of 0.50% of
Managed Assets that is paid monthly by First Trust from its investment advisory
fee.

First Trust agreed to waive fees in an amount equal to 0.35% of the average
daily Managed Assets of the Fund for the first two years of the Fund's
operations through June 27, 2008. The Sub-Advisor agreed to bear a portion of
this waiver obligation by reducing the amount of its sub-advisory fee to 0.20%.
Waivers are reported as "Fees waived by the investment advisor" in the Statement
of Operations.

PFPC Inc. ("PFPC"), an indirect, majority-owned subsidiary of The PNC Financial
Services Group, Inc., serves as the Fund's Administrator and Transfer Agent in
accordance with certain fee arrangements. PFPC Trust Company, also an indirect,
majority-owned subsidiary of The PNC Financial Services Group, Inc., serves as
the Fund's Custodian in accordance with certain fee arrangements.

                              APRIL 30, 2008 (UNAUDITED)

Each Trustee who is not an officer or employee of First Trust, any sub-advisor
or any of their affiliates ("Independent Trustees") is paid an annual retainer
of $10,000 per trust for the first 14 trusts of the First Trust Fund Complex and
an annual retainer of $7,500 per trust for each subsequent trust added to the
First Trust Fund Complex. The annual retainer is allocated equally among each of
the trusts. No additional meeting fees are paid in connection with board or
committee meetings.

Additionally, the Lead Independent Trustee is paid $10,000 annually, and the
Chairman of the Audit Committee is paid $5,000 annually, with such compensation
paid by the trusts in the First Trust Fund Complex and divided among those
trusts. Trustees are also reimbursed by the trusts in the First Trust Fund
Complex for travel and out-of-pocket expenses in connection with all meetings.
Effective January 1, 2008, each of the chairmen of the Nominating and Governance
Committee and the Valuation Committee are paid $2,500 to serve in such
capacities, with such compensation paid by the trusts in the First Trust Fund
Complex and divided among those trusts. Also effective January 1, 2008, the Lead
Independent Trustee and each committee chairman will serve two year terms.

                      4. PURCHASES AND SALES OF SECURITIES

Cost of purchases and proceeds from sales of investment securities, excluding
U.S. government and short-term investments, for the six months ended April 30,
2008, aggregated $27,566,925 and $27,394,206, respectively.

As of April 30, 2008, the aggregate gross unrealized appreciation for all
securities in which there was an excess of value over tax cost was $1,591,636,
and the aggregate gross unrealized depreciation for all securities in which
there was an excess of tax cost over value was $14,805,346.

                                5. COMMON SHARES

As of April 30, 2008, 2,978,819 of $0.01 par value Common Shares were issued. An
unlimited number of Common Shares has been authorized under the Fund's Dividend
Reinvestment Plan.

COMMON SHARE TRANSACTIONS WERE AS FOLLOWS:

                           6. AUCTION PREFERRED SHARES

The Fund's Declaration of Trust authorizes the issuance of an unlimited number
of preferred shares of beneficial interest, par value $0.01 per share, in one or
more classes or series, with rights as determined by the Board of Trustees
without the approval of Common Shareholders. As of April 30, 2008, the Fund has
880 Series M Auction Preferred Shares ("Preferred Shares") outstanding with a
liquidation value of $25,000 per share. The Preferred Shares offering costs of
$204,000 and commissions of $220,000 were charged to capital of Common Shares
for the period ended October 31, 2006. During the year ended October 31, 2007,
it was determined that actual offering costs from the Fund's Preferred Share
offering in September 2006 were less than the estimated offering costs by
$25,753. Therefore, paid-in-capital was increased by that amount.

The Fund is required to meet certain asset coverage tests with respect to the
Preferred Shares. If the Fund fails to maintain eligible assets having an
aggregated discounted value at least equal to the Preferred Shares basic
maintenance amount as of any valuation date and the failure is not cured on or
before the related asset coverage cure date, the Fund will be required in
certain circumstances to redeem certain Preferred Shares.

An auction of the Preferred Shares is generally held every 7 days. Existing
shareholders may submit an order to hold, bid or sell such shares at par value
on each auction date.

NOTES TO FINANCIAL STATEMENTS - (CONTINUED)

                FIRST TRUST TAX-ADVANTAGED PREFERRED INCOME FUND
                           APRIL 30, 2008 (UNAUDITED)

The annual dividend rate in effect as of April 30, 2008 was 4.05%. The dividend
rate, as set by the auction process, is generally expected to vary with
short-term interest rates. The high and low annual dividend rates during the six
months ended April 30, 2008, were 5.10% and 2.65%, respectively, and the average
dividend rate was 4.34%. These rates may vary in a manner not related directly
to the income received on the Fund's assets, which could have either a
beneficial or detrimental impact on net investment income and gains available to
Common Shareholders.

                               7. CREDIT AGREEMENT

The Fund has a credit agreement with the Custodial Trust Company of Bear
Stearns, under which the Fund may borrow from the Custodial Trust Company an
aggregate amount of up to the lesser of $20,000,000 or the maximum amount the
Fund is permitted to borrow under the 1940 Act. This credit agreement has no
maturity date and can be paid or called at any time. For the six months ended
April 30, 2008, the Fund had no borrowings under this credit agreement.

                               8. INDEMNIFICATION

The Fund has a variety of indemnification obligations under contracts with its
service providers. The Fund's maximum exposure under these arrangements is
unknown. However, the Fund has not had prior claims or losses pursuant to these
contracts and expects the risk of loss to be remote.

                        9. CHANGE IN INVESTMENT STRATEGY

The Fund currently invests 80% of its managed assets in preferred securities
that the Sub-Advisor believes at the time of investment are eligible to pay
dividends that qualify for certain federal income tax treatment as
tax-advantaged when received by Shareholders of the Fund ("Tax-Advantaged"). On
March 3, 2008, the Board of Trustees approved a change in investment strategy
allowing any Tax-Advantaged hybrid preferred securities to be included in the
80% strategy. The non-fundamental change in investment strategy described above,
which will be effective on or about September 1, 2008, was not required to be,
and was not, approved by the shareholders of the Fund. The change in strategy
may be changed by the Board of Trustees without shareholder approval.

                             10. RISK CONSIDERATIONS

INVESTMENT RISK: An investment in the Fund's Common Shares is subject to
investment risk, including the possible loss of the entire principal invested.
An investment in Common Shares represents an indirect investment in the
securities owned by the Fund. The value of these securities, like other market
investments, may move up or down, sometimes rapidly and unpredictably. Common
Shares at any point in time may be worth less than the original investment, even
after taking into account the reinvestment of Fund dividends and distributions.
Security prices can fluctuate for several reasons including the general
condition of the bond market, or when political or economic events affecting the
issuers occur.

LOSS OF "QUALIFIED DIVIDEND INCOME" STATUS: Without further legislation, the tax
advantage associated with "qualified dividend income" is set to expire for tax
years beginning January 1, 2011. The loss of such tax advantage would reduce the
after-tax yield of any income from the Fund's investments that would otherwise
constitute "qualified dividend income," thereby reducing the overall level of
tax-advantaged current income available to individual and other non-corporate
holders of Common Shares.

NON-INVESTMENT GRADE SECURITIES RISK: The Fund may invest up to 50% of its
Managed Assets in non-investment grade securities. Below-investment grade
securities are rated below "Baa" by Moody's Investors Service, Inc., below "BBB"
by Standard & Poor's Ratings Group, comparably rated by another nationally
recognized statistical rating organization or, if unrated, determined to be of
comparable credit quality by the Sub-Advisor. Below-investment grade debt
instruments are commonly referred to as "high-yield" or "junk" bonds and are
considered speculative with respect to the issuer's capacity to pay interest and
repay principal and are susceptible to default or decline in market value due to
adverse economic and business developments. The market values for high-yield
securities tend to be volatile, and these securities are less liquid than
investment grade debt securities.

ECONOMIC CONDITION RISK: Adverse changes in economic conditions are more likely
to lead to a weak capacity of high-yield issuers to make principal payments and
interest payments than an investment grade issuer. An economic downturn could
severely affect the ability of highly leveraged issuers to service their debt
obligations or repay their obligations upon maturity. Under adverse market or
economic conditions, the secondary market for high-yield securities could
contract further independent of any adverse changes in the conditions of a
particular issuer and these securities may become illiquid. As a result, the
Fund could find it more difficult to sell these securities or may be able to
sell the securities only at prices lower than if such securities were widely
traded.

                                    Page 17

                FIRST TRUST TAX-ADVANTAGED PREFERRED INCOME FUND
                           APRIL 30, 2008 (UNAUDITED)

INTEREST RATE RISK: The Fund is also subject to interest rate risk. Interest
rate risk is the risk that fixed-income securities will decline in value because
of changes in market interest rates. Investments in debt securities with
long-term maturities may experience significant price declines if long-term
interest rates increase.

FINANCIAL SERVICES SECTOR RISK: The Fund's assets will be primarily invested in
securities issued by companies in the financial services sector, which includes
banks and thrifts, financial services and insurance companies and investment
firms. In addition, within the financial services sector, the Fund's investments
will be concentrated in the banking industry. A fund concentrated in a single
industry is likely to present more risks than a fund that is broadly diversified
over several industries. Banks, thrifts and their holding companies are
especially subject to the adverse effects of economic recession; volatile
interest rates; portfolio concentrations in geographic markets and in commercial
and residential real estate loans; and competition from new entrants in their
fields of business.

SMALLER ISSUER RISK: The Fund may invest in securities issued by smaller
financial institutions and insurance companies that may present greater
opportunities for income, and may also involve greater investment risk than
larger, more established companies. As a result, the prices of the securities of
such smaller companies may fluctuate to a greater degree than the prices of
securities of other issuers.

ILLIQUID/RESTRICTED SECURITIES RISK: The Fund may invest in securities that, at
the time of investment, are illiquid. The Fund may also invest in restricted
securities. Investments in restricted securities could have the effect of
increasing the amount of the Fund's assets invested in illiquid securities if
qualified institutional buyers are unwilling to purchase these securities.
Illiquid and restricted securities may be difficult to dispose of at a fair
price at the times when the Fund believes it is desirable to do so. The market
price of illiquid and restricted securities generally is more volatile than that
of more liquid securities, which may adversely affect the price that the Fund
pays for or receives upon the sale of such securities. Investment of the Fund's
assets in illiquid and restricted securities may restrict the Fund's ability to
take advantage of market opportunities. The risks associated with illiquid and
restricted securities may be particularly acute in situations in which the
Fund's operations require cash and could result in the Fund borrowing to meet
its short-term needs or incurring losses on the sale of illiquid or restricted
securities. In order to dispose of an unregistered security, the Fund, where it
has contractual rights to do so, may have to cause such security to be
registered.

LEVERAGE RISK: The Fund uses leverage for investment purposes by issuing
preferred shares. Its leveraged capital structure creates special risks not
associated with unleveraged funds having similar investment objectives and
policies. These include the possibility of higher volatility of the net asset
value of the Fund and the preferred shares' asset coverage. The Fund may from
time to time consider changing the amount of the leverage in response to actual
or anticipated changes in interest rates or the value of the Fund's investment
portfolio. There can be no assurance that the leverage strategies will be
successful.

AUCTION RISK: If an auction fails you may not be able to sell some or all of
your preferred shares. No third parties related to the auction nor the Fund
itself are obligated to purchase preferred shares in an auction or otherwise,
nor is the Fund required to redeem preferred shares in the event of a failed
auction.

                              11. SUBSEQUENT EVENTS

Two issuers of securities held by the Fund have suspended their quarterly
dividends in the Fund's last quarter resulting in the Fund's reduction in the
June dividend to Common Shareholders. On Friday, June 6, 2008, Heartland
Financial ("Heartland"), suspended quarterly dividends on its preferred
securities held by the Fund. On June 6, 2008, the Fund held a total of
$6,000,000 aggregate par value of Series B Fixed-Rate Non-Cumulative Redeemable
Perpetual Preferred Shares ("Heartland Preferred Shares"). Such action by
Heartland resulted in a reduction in the price of the Heartland Preferred
Shares, which led to a significant decline in the Funds NAV. Primarily as a
result of such event, the Fund's net asset value declined from $13.07 as of
Thursday, June 5, 2008, to $11.54 as of Friday, June 6, 2008, at 4:00 p.m.
Eastern Time, an approximate 11.7% reduction. On May 12, 2008, IndyMac Bancorp,
Inc. suspended quarterly dividends on its preferred securities held by the Fund.
On May 12, 2008, the Fund held a total of $5,000,000 aggregate par value of
Fixed-Rate Preferred Shares of IndyMac Bancorp, Inc.

On June 9, 2008, the Fund declared a dividend of $0.21 per share to Common
Shareholders of record June 20, 2008, payable June 30, 2008.

ADDITIONAL INFORMATION

                           APRIL 30, 2008 (UNAUDITED)

                           DIVIDEND REINVESTMENT PLAN

If your Common Shares are registered directly with the Fund or if you hold your
Common Shares with a brokerage firm that participates in the Fund's Dividend
Reinvestment Plan (the "Plan"), unless you elect, by written notice to the Fund,
to receive cash distributions, all dividends, including any capital gain
distributions, on your Common Shares will be automatically reinvested by PFPC
Inc. (the "Plan Agent"), in additional Common Shares under the Plan. If you
elect to receive cash distributions, you will receive all distributions in cash
paid by check mailed directly to you by the Plan Agent as dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will
receive will be determined as follows:

      (1)   If Common Shares are trading at or above net asset value ("NAV") at
            the time of valuation, the Fund will issue new shares at a price
            equal to the greater of (i) NAV per Common Share on that date or
            (ii) 95% of the market price on that date.

      (2)   If Common Shares are trading below NAV at the time of valuation, the
            Plan Agent will receive the dividend or distribution in cash and
            will purchase Common Shares in the open market, on the AMEX or
            elsewhere, for the participants' accounts. It is possible that the
            market price for the Common Shares may increase before the Plan
            Agent has completed its purchases. Therefore, the average purchase
            price per share paid by the Plan Agent may exceed the market price
            at the time of valuation, resulting in the purchase of fewer shares
            than if the dividend or distribution had been paid in Common Shares
            issued by the Fund. The Plan Agent will use all dividends and
            distributions received in cash to purchase Common Shares in the open
            market within 30 days of the valuation date except where temporary
            curtailment or suspension of purchases is necessary to comply with
            federal securities laws. Interest will not be paid on any uninvested
            cash payments.

You may elect to opt-out of or withdraw from the Plan at any time by giving
written notice to the Plan Agent, or by telephone at (800) 334-1710, in
accordance with such reasonable requirements as the Plan Agent and Fund may
agree upon. If you withdraw or the Plan is terminated, you will receive a
certificate for each whole share in your account under the Plan and you will
receive a cash payment for any fraction of a share in your account. If you wish,
the Plan Agent will sell your shares and send you the proceeds, minus brokerage
commissions.

The Plan Agent maintains all Common Shareholders' accounts in the Plan and gives
written confirmation of all transactions in the accounts, including information
you may need for tax records. Common Shares in your account will be held by the
Plan Agent in non-certificated form. The Plan Agent will forward to each
participant any proxy solicitation material and will vote any shares so held
only in accordance with proxies returned to the Fund. Any proxy you receive will
include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions
in Common Shares. However, all participants will pay a pro rata share of
brokerage commissions incurred by the Plan Agent when it makes open market
purchases.

Automatically reinvesting dividends and distributions does not mean that you do
not have to pay income taxes due upon receiving dividends and distributions.
Capital gains and income are realized, although cash is not received by you.
Consult your financial advisor for more information.

If you hold your Common Shares with a brokerage firm that does not participate
in the Plan, you will not be able to participate in the Plan and any dividend
reinvestment may be effected on different terms than those described above.

The Fund reserves the right to amend or terminate the Plan if in the judgment of
the Board of Trustees the change is warranted. There is no direct service charge
to participants in the Plan; however, the Fund reserves the right to amend the
Plan to include a service charge payable by the participants. Additional
information about the Plan may be obtained by writing PFPC Inc., 301 Bellevue
Parkway, Wilmington, Delaware 19809.

                      ADVISORY AND SUB-ADVISORY AGREEMENTS

BOARD CONSIDERATIONS REGARDING APPROVAL OF INVESTMENT MANAGEMENT AND
SUB-ADVISORY AGREEMENTS

The Board of Trustees of First Trust Tax-Advantaged Preferred Income Fund (the
"Fund"), including the Independent Trustees, unanimously approved the
continuation of the Investment Management Agreement (the "Advisory Agreement")
between the Fund and First Trust Advisors L.P. (the "Advisor") and the
Investment Sub-Advisory Agreement (the "Sub-Advisory Agreement" and together
with the Advisory Agreement, the "Agreements") among the Fund, the Advisor and
Stonebridge Advisors LLC (the "Sub-Advisor"), at a meeting held on March 3,
2008. The Board determined that the terms of the Agreements are fair and
reasonable and that the Agreements continue to be in the best interests of the
Fund.

To reach this determination, the Board considered its duties under the
Investment Company Act of 1940, as amended (the "1940 Act"), as well as under
the general principles of state law in reviewing and approving advisory
contracts; the requirements of the 1940 Act in such matters; the fiduciary duty
of investment advisers with respect to advisory agreements and compensation; the
standards used by courts in determining whether investment company boards have
fulfilled their duties; and the factors to be considered by the Board in voting
on such agreements. To assist the Board in its evaluation of the Agreements, the
Independent Trustees received a separate report from each of the Advisor and the
Sub-Advisor in advance of the Board meeting responding to a request for
information from counsel to the Independent Trustees. The reports, among other
things, outlined the services provided by the Advisor and the Sub-Advisor
(including the relevant personnel responsible for these services and their
experience); the advisory and sub-advisory fees for the Fund as compared to fees
charged by investment advisors and sub-advisors to comparable funds and as
compared to fees charged to other clients of the Advisor and the Sub-Advisor;
expenses of the Fund as compared to expense ratios of comparable funds; the
nature of expenses incurred in providing services to the Fund and the potential
for economies of scale, if any; financial data on the Advisor and the
Sub-Advisor; any fall-out benefits to the Advisor and the Sub-Advisor; and
information on the Advisor's and the Sub-Advisor's compliance programs. The
Independent Trustees also met separately with their independent legal counsel to
discuss the information provided by the Advisor and the Sub-Advisor. The Board
applied its business judgment to determine whether the arrangements between the
Fund and the Advisor and among the Fund, the Advisor and the Sub-Advisor are
reasonable business arrangements from the Fund's perspective as well as from the
perspective of shareholders.

In reviewing the Agreements, the Board considered the nature, quality and extent
of services provided by the Advisor and the Sub-Advisor under the Agreements.
With respect to the Advisory Agreement, the Board considered that the Advisor is
responsible for the overall management and administration of the Fund, including
the oversight of the Sub-Advisor. The Board noted the compliance program that
had been developed by the Advisor and considered that the compliance program
includes policies and procedures for monitoring the Sub-Advisor's compliance
with the 1940 Act and the Fund's investment objectives and policies. The Board
noted that First Trust Portfolios L.P., an affiliate of the Advisor, has an
ownership interest in the Sub-Advisor and that this investment allows for more
informed oversight of the Sub-Advisor by the Advisor. With respect to the
Sub-Advisory Agreement, the Board received a presentation from representatives
of the Sub-Advisor discussing the services that the Sub-Advisor provides to the
Fund and how the Sub-Advisor meets the Fund's investment objectives. In light of
the information presented and the considerations made, the Board concluded that
the nature, quality and extent of services provided to the Fund by the Advisor
and the Sub-Advisor under the Agreements have been and are expected to remain
satisfactory and that the Sub-Advisor generally managed the Fund consistent with
its investment objectives and policies.

ADDITIONAL INFORMATION - (CONTINUED)

                FIRST TRUST TAX-ADVANTAGED PREFERRED INCOME FUND
                           APRIL 30, 2008 (UNAUDITED)

The Board considered the advisory and sub-advisory fees paid under the
Agreements. The Board reviewed data prepared by Lipper Inc. ("Lipper"), an
independent source, showing the management fees and expense ratios of the Fund
as compared to the management fees and expense ratios of one peer group selected
by Lipper and a second peer group selected by the Advisor. The Board discussed
with representatives of the Advisor the differences between the two peer groups
and the limitations in creating a relevant peer group for the Fund given the
Fund's unique composition. The Board also considered the difficulties in
comparing funds with different amounts of assets and using different types of
leverage. Based on the information provided, the Board noted that the Fund's
management fees were in the fifth quintile of both the Lipper peer group and the
Advisor peer group, and that the Fund's expense ratio was in the fourth and
fifth quintiles of the Lipper peer group and the Advisor peer group,
respectively. The Board considered that through June 27, 2008, the Advisor has
agreed to reduce its annual management fee to 0.65% of the Fund's Managed Assets
in order to reimburse the Fund for certain fees and expenses incurred by the
Fund. The Board noted that the Advisor's waiver was reflected in the Lipper
information. The Board also considered the sub-advisory fee rate and how it
related to the overall management fee structure of the Fund and noted that the
Advisor pays the Sub-Advisor out of the advisory fees it receives from the Fund.
The Board noted that the Sub-Advisor has agreed to bear a portion of the expense
reduction by reducing the amount of its full sub-advisory fee to 0.20% of the
Fund's Managed Assets through June 27, 2008. Finally, the Board considered the
advisory fees paid to the Advisor by similar funds, and noted that the Advisor
does not provide advisory services to any other clients with investment
objectives and policies similar to the Fund's. The Board considered that the
Sub-Advisor does not provide services to other clients that have similar
investment objectives and policies to the Fund.

The Board also considered the Fund's performance for the one-year period ended
September 30, 2007 as compared to the performance of a relevant blend of
benchmark indices and to a performance group selected by Lipper. The Board
considered the difficulty in creating a relevant performance group for the Fund
given its unique strategy and asset mix. The Board noted that the Fund's
performance was in the third quintile of the performance group for the period
and that the Fund underperformed its benchmark for the period. The Board also
considered performance data provided by the Advisor for the one-year and
since-inception periods ended December 31, 2007, noting that over these periods,
the Fund had negative total returns and underperformed both its benchmark and
peer funds. The Board noted that the benchmark and peer funds also had negative
total returns during the one-year and since-inception periods ended December 31,
2007, and considered reasons for the overall underperformance of the strategy,
including the ongoing turmoil in the credit market. The Sub-Advisor also
informed the Board that one of the Fund's larger holdings had suspended
dividends as of the morning of the Board meeting. The Board also considered an
analysis prepared by the Advisor on benefits provided by the Fund's leverage. In
addition, the Board considered the market price and net asset value performance
of the Fund since inception, and compared the Fund's premium/discount to the
average and median premium/discount of the Lipper peer group, noting that the
Fund's premium/discount was generally indicative of the asset class and market
events. The Board concluded that the Fund's performance was consistent with the
Fund's investment strategy and reflective of the performance of the asset class.

On the basis of all the information provided on the fees, expenses and
performance of the Fund, the Board concluded that the advisory and sub-advisory
fees were reasonable and appropriate in light of the nature, quality and extent
of services provided by the Advisor and Sub-Advisor under the Agreements.

The Board noted that the Advisor has continued to invest in personnel and
infrastructure and had noted that the advisory fee is not structured to pass the
benefits of any economies of scale on to the shareholders as the Fund's assets
grow. The Board concluded that the management fee reflects an appropriate level
of sharing of any economies of scale. The Board also considered the costs of the
services provided and profits realized by the Advisor from serving as investment
manager to closed-end funds for the twelve months ended December 31, 2007, as
set forth in the materials provided to the Board. The Board noted the inherent
limitations in the profitability analysis, and concluded that the Advisor's
profitability appeared to be not excessive in light of the services provided to
the Fund. In addition, the Board considered and discussed any ancillary benefits
derived by the Advisor from its relationship with the Fund and noted that the
typical fall-out benefits to the Advisor such as soft dollars are not present.
The Board concluded that any other fall-out benefits received by the Advisor or
its affiliates would appear to be attenuated.

The Board noted that the Sub-Advisor did not identify any economies of scale
realized in connection with providing services to the Fund and represented that,
with the fee waiver, the Sub-Advisor was providing sub-advisory services to the
Fund at a loss. The Board considered the Advisor's representation that First
Trust Portfolios L.P. has committed to provide any necessary financing for the
Sub-Advisor. The Board noted that the Sub-Advisor does not maintain any
soft-dollar arrangements and that the Sub-Advisor indicated that it does not
receive any material fall-out benefits from its relationship to the Fund.

Based on all of the information considered and the conclusions reached, the
Board, including the Independent Trustees, determined that the terms of the
Agreements continue to be fair and reasonable and that the continuation of the
Agreements is in the best interests of the Fund. No single factor was
determinative in the Board's analysis.
