Keystone Quality Bond Fund (B-1)
Seeks generous income and capital preservation from high quality bonds.

Dear Shareholder:

We are pleased to report on the activities of Keystone Quality Bond Fund
(B-1) for the twelve-month period which ended October 31, 1996. Following our
letter we have included a discussion with your Fund's manager and complete
financial information.

Performance

Your Fund returned 5.08% for the six-month period and 3.99% for the
twelve-month period which ended October 31, 1996. For the same periods, the
Lehman Aggregate Bond Index--a widely recognized index of corporate,
government and mortgage securities--returned 5.29% for the six-month period
and 5.83% for the twelve-month period.

  Keystone Quality Bond Fund (B-1) provided satisfactory performance during a
period of sharp price fluctuations as interest rates rose and then fell in
reaction to changing economic conditions. Fund performance improved
particularly during the last six months of the period.

  While interest rates were relatively unchanged from their levels of one year
ago, the credit markets endured considerable short-term price volatility
during the twelve-month period. In November and December 1995, interest rates
trended down as economic growth slowed from moderate levels, inflation
remained under control and the government appeared to be making progress
toward reducing the federal budget deficit. Most investors expected these
trends to continue into 1996. On October 31, 1996 the benchmark 30-year U.S.
Treasury bond yielded 6.35%. By January 1996 Treasuries had reached a low of
5.97% on this favorable news.

  During the first quarter of 1996 economic reports showed
stronger-than-expected economic growth and employment gains, which increased
fears of higher inflation rates. Because inflation reduces returns to bond
holders, interest rates generally rose with each economic report that
indicated strong growth. By early July rates had peaked at 7.19%. As rates
rose, prices generally declined for nearly all fixed income investments.

  Expectations of stronger growth moderated during the third quarter of 1996
as it appeared that the strong growth of the first half of the year was
slowing. Still watchful for signs of future inflation, investors gained
confidence that this favorable environment could be sustained and interest
rates began to move within a narrow range. On October 31, 1996 the 30-year
Treasury stood at 6.82%, not far from where it was at the beginning of the
fiscal period.

Portfolio strategy

Over the past six months, we restructured Keystone Quality Bond Fund (B-1) to
improve stability and enhance long-term potential total returns. We invested
a portion of the Fund in government bonds of Canada, Germany and Spain. With
their attractive yields, high quality and solid economic fundamentals, we
believed these investments offered good relative values. All transactions
were currency-hedged into U.S. dollars to protect the portfolio from foreign
currency fluctuations.

  We also increased your Fund's investments in collateralized mortgage
obligations (CMOs), asset-backed securities, and bonds in the bank and
finance sectors. We believe these securities contributed favorably to your
Fund's income and total return. In its entirety, we believe the portfolio's
new structure increased diversification while maintaining a high degree of
quality and liquidity.

Keystone Quality Bond Fund (B-1)

  Keystone Quality Bond Fund (B-1) is designed for conservative,
income-oriented investors. We invest in a selection of high quality fixed
income securities, which include among others, U.S. government obligations,
mortgage-backed and asset-backed securities, and high-quality corporate
bonds. We apply careful credit analysis in selecting high quality securities
for the portfolio. We attempt to identify securities that we believe will
perform well given our expectations for the market environment. We believe
that your Fund's ability to diversify and be flexible are key elements in
navigating the changing conditions of the fixed income markets.

  Looking ahead, we anticipate a stable-to-positive environment for high
quality bonds. We expect moderate economic growth and low inflation to
provide a positive background for interest rates to move within a narrow
range through early 1997.

New portfolio manager

After 20 years of distinguished service with Keystone, your Fund's manager
Barbara McCue has retired effective September 30, 1996. The leader of
Keystone's high grade bond team, Christopher P. Conkey, has assumed
responsibilities as your Fund's portfolio manager. Mr. Conkey is a Chartered
Financial Analyst and has over 13 years of investment experience. He
currently manages several other Keystone funds that invest in high grade
bonds. We look forward to his contribution to your Fund's management.

Keystone acquired by First Union Corporation

On another note, we are pleased to inform you that Keystone has been acquired
by First Union Corporation. First Union is a financial services firm based in
Charlotte, North Carolina. It is the nation's sixth largest bank holding
company with assets of approximately $130 billion. First Union, through its
wholly-owned subsidiary Evergreen Asset Management Corp., together with
Keystone mutual funds, manages more than $30 billion in 70 mutual funds.
While Keystone will remain a separate entity and will continue to provide
investment advisory and management services to the Fund, services will be
provided under the "Evergreen Keystone Funds" name. We believe First Union's
acquisition of Keystone strengthens the investment management services we
provide you.

  We appreciate your continued support of Keystone Quality Bond Fund (B-1). If
you have any questions or comments about your investment, we encourage you to
write to us.

Sincerely,

/s/ Albert H. Elfner, III

A Discussion With
Your Fund Manager

[PHOTO OF CHRISTOPHER P. CONKEY]

Christopher P. Conkey is portfolio manager of your Fund and
heads Keystone's high grade bond team. A Chartered
Financial Analyst, Mr. Conkey has 13 years of experience
managing fixed-income investments. He holds a BA in
economics from Clark University and an MBA in finance from
Boston University. Together with analysts David J. Bowers
and Gary E. Pzegeo, he evaluates interest rate and credit risk
in selecting high quality bonds for Keystone fixed income funds.

Q  What was the investment climate like for high quality bonds over the past
year?

A  The climate for high quality bonds changed several times over the past
year. There was a high degree of price volatility throughout much of the
period, as investors revised their interest rate and economic forecasts.
Despite these fluctuations, however, interest rates were relatively unchanged
at the end of this reporting period from one year ago.

Q  What changed the outlooks for interest rates and the economy?

A  Stronger-than-expected growth in employment and consumer spending in the
first quarter of 1996 caused investors to revise their economic and interest
rate forecasts. Interest rates had fallen to near historic lows during much
of 1995 on the outlook for a slow economy and low inflation. The reports of
strength in employment and consumer activity stimulated concerns
that the economy might be more robust than expected.
Interest rates rose and bond prices fell during that time.

  By mid-year, signs of moderating economic growth appeared, relieving
inflation fears. While watchful of preliminary signs of future inflation,
investors became more confident that this trend of moderate growth and low
inflation could be sustained.

Q  What strategies did you employ during these changing market climates?

A  We restructured the portfolio's assets and adjusted its average maturity.
We believe the combination reduced the Fund's risk to U.S. interest rate
fluctuations, increased yield and improved diversification.

  First, we reduced the Fund's holdings in U.S. government securities from 48%
to 5% of net assets. Since U.S. government securities carry no credit risk,
their prices are primarily influenced by the movement in interest rates. We
believe reducing the portfolio's exposure to interest rate risk increased
stability, particularly in light of the price volatility over the past year.

  We reinvested the proceeds from these sales in non-dollar foreign government
bonds, collateralized mortgage obligations (CMOs), asset-backed securities,
and bonds in the bank and finance sectors. These bonds improved
diversification, increased income, and provided price appreciation to the
Fund's portfolio.

Asset Allocation
as of October 31, 1996

[TABULAR REPRESENTATION OF PIE CHART]

Corporates                                     (31.7%)
Collateralized mortgage obligations (CMOs)     (22.3%)
Foreign                                        (15.6%)
Mortgage-backed                                (13.6%)
Asset-backed                                   (10.6%)
U.S. government & agency                        (5.1%)
Other(1)                                        (1.1%)

(as a percent of net assets)

  We adjusted average maturity, ultimately shortening it when interest rates
rose last spring. As of October 31, 1996, the Fund's average maturity stood
at 11 years. The average quality of Keystone Quality Bond Fund (B-1) was AA+,
the second highest rating available from Standard and Poor's Corporation.

Q  Why did you invest in the foreign sector?

A  The foreign sector offered higher yields and greater potential for capital
appreciation than many domestic alternatives. We did not increase credit risk
in the foreign sector, preferring to emphasize securities with high quality
ratings. Further, all of the investments were currency-hedged, to protect our
holdings from foreign currency exchange rate changes.

  We invested in the government bonds of Canada, Germany and Spain; countries
that we believed offered attractive values based on solid economic
fundamentals, stable political environments and large, liquid securities
markets. In fact, interest rates in these countries have fallen over the past
year resulting in price appreciation. In addition, our foreign investments
avoided the price declines experienced in the U.S. credit markets.

Q  How about other sectors?

A  Collateralized mortgage obligations and asset-backed securities also
offered investors higher yields than U.S. government bonds, while enabling
the Fund to maintain credit quality. We invested in well structured,
AAA-rated securities. We concentrated on commercial loans and securities that
were collateralized by home equity loans and credit card receivables. We
chose these sectors because of their link to the consumer. Consumer
confidence ran high throughout the period, due to strength in employment,
income growth, and improving net wealth which was caused by a rising stock
market and generally higher housing prices. We believed that the strength of
the consumer sector would have a favorable effect on these securities versus
alternative investments.

  We also increased the Fund's investments in the bank and finance sector as
interest rates rose. We believed that higher U.S. rates would eventually slow
economic growth. Slower growth historically has resulted in falling interest
rates. Typically, banks and finance companies have benefitted from this type
of environment. Towards the end of the reporting period this scenario of
lower rates appeared to be unfolding.

Q  What is your outlook for the next six months?

A  We believe the next six months should be a neutral environment for high
quality bonds with interest rates fluctuating in a narrow range. We
anticipate moderate economic growth accompanied by low inflation. On an
annual basis, we think the economy will grow at a pace of 2-2-1/2% and that
inflation, as measured by the consumer price index (CPI), will stay in the
area of 3%.

Q  With interest rates at relatively low levels, do you believe that bonds
offer good long term value?

A  We believe they do. While nominal interest rates have been relatively low,
"real" interest rates, or the rate received by investors after subtracting
inflation, continues to be attractive. For example, the 30-year U.S. Treasury
bond had a yield of 6.82% as of October 31, 1996.

Portfolio Quality Summary
as of October 31, 1996

[TABULAR REPRESENTATION OF PIE CHART]

AAA                               (36.3%)
U.S. government and agency(3)     (26.6%)
A                                 (15.2%)
AA                                (11.0%)
BBB                               (10.9%)

(as a percentage of portfolio assets)

Inflation was recently about 3%. Thus, the real return after subtracting
inflation was approximately 3.82% at the end of the period, a historically
attractive level.

  Like most investments, high quality bonds can experience periods of
short-term price volatility. Over the long-run, however, high-quality bonds
have demonstrated relative stability and attractive income. We believe high
quality bonds will continue to produce solid total returns in the future. In
our opinion, the Fund serves an important role in a well-rounded investment
portfolio.

(2) Where Standard & Poor's ratings were not available, we have used ratings
    from Moody's Investor Service, Inc., Fitch Investors' Service, Inc., or
    ratings assigned by another nationally recognized statistical rating
    organization.
(3) Includes all U.S. government and agency securities including CMOs, asset-
    backed and mortgage pass-through securities issued by the U.S. government
    or its agencies.

Ratings are very important to evaluating bonds. What do they mean?

Bond ratings provide an indication of the relative investment quality of an
issuer. Each rating agency uses its own criteria for assigning ratings. In
general, each agency examines the ability of an issuer to maintain debt
protection levels in periods of recession as well as recovery. Bonds with
identical ratings are not necessarily equal. Different industries have
different business risks. However, most bonds within a certain rating
category tend to have similar characteristics. The following table briefly
defines investment grade bond ratings.

                        Investment Grade Bond Ratings

Moody's Investors Service          S&P
Aaa                                AAA      Highest Quality,
                                            lowest likelihood of default
Aa                                 AA       High Quality
A                                  A        Upper Medium Grade
Baa                                BBB      Medium Grade

We use bond ratings as one component of our credit research. For Keystone
Quality Bond Fund (B-1), we consider only investment-grade securities. That
is, bonds rated AAA, AA, A, and BBB. Lower rated bonds are considered
speculative grade.

This chart graphically compares your Fund's performance to certain investment
indexes. It is the result of fund performance guidelines issued by the
Securities and Exchange Commission. The intent is to provide investors with
more information about their investment.

Components of the chart

The chart is composed of several lines that represent the accumulated value
of an initial $10,000 investment for the period indicated. The lines
illustrate a hypothetical investment in:

1. Keystone Quality Bond Fund (B-1)

Your Fund seeks the highest possible income consistent with preservation of
principal. The return is quoted after deducting sales charges (if
applicable), fund expenses, and transaction costs and assumes reinvestment of
all distributions.

2. Lehman Aggregate Bond Index (LABI)

The LABI is a broad-based, unmanaged fixed income index of U.S. government,
corporate and mortgage-backed securities. It represents the price change and
coupon income of several thousand securities of various credit qualities and
maturities. Securities are selected and compiled by Lehman Brothers, Inc.
according to criteria that may be unrelated to your Fund's investment
objective. It would be difficult for most individual investors to duplicate
this index.

3. Consumer Price Index (CPI)

This index is a widely recognized measure of the cost of goods and services
produced in the U.S. The index contains factors such as prices of services,
housing, food, transportation and electricity which are compiled by the U.S.
Bureau of Labor Statistics. The CPI is generally considered a valuable
benchmark for investors who seek to outperform increases in the cost of
living.

  These indexes do not include transaction costs associated with buying and
selling securities, and do not hold cash to meet redemptions. It would be
difficult for most individual investors to duplicate these indexes.

Understanding what the chart means

  The chart demonstrates your Fund's performance in relation to a well known
investment index and to increases in the cost of living. It is important to
understand what the chart shows and does not show.

  This illustration is useful because it charts Fund and index performance
over the same time frame and over a long period. Long-term performance is a
more reliable and useful measure of performance than measurements of
short-term returns or temporary swings in the market. Your financial adviser

evaluate fund performance in conjunction with the other important financial
considerations such as safety, stability and consistency.

Limitations of the chart

The chart, however, limits the evaluation of Fund performance in several
ways. Because the measurement is based on total returns over an extended
period of time, the comparison often favors those funds which emphasize
capital appreciation when the market is rising. Likewise, when the market is
declining, the comparison usually favors those funds which take less risk.

Performance can be distorted

Funds which are more conservative in their orientation and which place an
emphasis on capital preservation will tend to compare less favorably when the
market is rising. In addition, funds which have income as one of their
objectives also will tend to compare less favorably to relevant indexes.

  Indexes may also reflect the performance of some securities which a fund may
be prohibited from buying. A bond fund, for example, may be limited to
investments in only high quality bonds, or a stock fund may only be able to
buy stocks that have been traded on a stock exchange for a minimum number of
years or stocks that have a certain market capitalization. Indexes usually do
not have the same investment restrictions as your Fund.

Indexes do not include costs of investing

  The comparison is further limited in its utility because the indexes do not
take into account any deductions for sales charges, transaction costs or
other fund expenses. Your Fund's performance figures do reflect such
deductions. Sales charges--whether up-front or deferred--pay for the cost of
the investment advice of your financial adviser. Transaction costs pay for
the costs of buying and selling securities for your Fund's portfolio. Fund
expenses pay for the costs of investment management and various shareholder
services. None of these costs are reflected in index total returns. The
comparison is not completely realistic because an index cannot be duplicated
by an investor--even an unmanaged index--without incurring some charges and
expenses.

One of several measures

The chart is one of several tools you can use to understand your investment.
It should be read in conjunction with the Fund's prospectus, and annual and
semiannual reports. Also, your financial adviser, who understands your
personal financial situation, can best explain the features of your Keystone
fund and how it applies to your financial needs.

Future returns may be different

Shareholders also should be mindful that the long-run performance of either
the Fund or the indexes is not representative of what shareholders should
expect to receive from their Fund investment in the future; it is presented
to illustrate only past performance and is not a guarantee of future returns.

                                 Glossary of
                              Mutual Fund Terms

  MUTUAL FUND--A company which combines the investment money of many people
whose financial goals are similar, and invests that money in a variety of
securities. A mutual fund allows the smaller investor the benefits of
diversification, professional management and constant supervision usually
available only to large investors.

  PORTFOLIO MANAGER--An investment professional who is responsible for
managing a portfolio's assets prudently and making appropriate investment
decisions, such as which securities to buy, hold and sell, based on the
investment objectives of the portfolio.

  STOCK--Equity or ownership interest in a corporation, which represents a
claim on the corporation's assets and earnings.

  BOND--Security issued by a government or corporation to those from whom it
has borrowed money. A bond usually promises to pay interest income to the
bondholder at regular intervals and to repay the entire amount borrowed at
maturity date.

  CONVERTIBLE SECURITY--A corporate security (usually preferred stock or
bonds) that is exchangeable for a set number of another security type
(usually common stocks) at a pre-stated price.

  MONEY MARKET FUND--A mutual fund whose assets are invested in a diversified
portfolio of short- term securities, including commercial paper, bankers'
acceptances, certificates of deposit and other short-term instruments. The
fund pays income which can fluctuate daily. Liquidity and safety of principal
are primary objectives.

  NET ASSET VALUE (NAV) PER SHARE--The value of one share of a mutual fund.
The NAV per share is determined by subtracting a fund's total liabilities
from its total assets, and dividing that amount by the number of fund shares
outstanding.

  DIVIDEND--A per share distribution of the income earned from the fund's
portfolio holdings. When a dividend distribution is made, the fund's net
asset value drops by the amount of the distribution because the distribution
is no longer considered part of the fund's assets.

  CAPITAL GAIN--The profit from the sale of securities, less any losses.
Capital gains are paid to fund shareholders on a per share basis. When a
capital gain distribution is made, the fund's net asset value drops by the
amount of the distribution because the distribution is no longer considered
part of the fund's assets.

  YIELD--The annualized rate of income as measured against the current net
asset value of fund shares.

  TOTAL RETURN--The change in value of a fund investment over a specified
period of time, taking into account the change in a fund's market price and
the reinvestment of all fund distributions.

  SHORT-TERM--An investment with a maturity of one year or less.

  LONG-TERM--An investment with a maturity of greater than one year.

  AVERAGE MATURITY--The average number of days until the notes, drafts,
acceptances, bonds or other debt instruments in a portfolio become due and
payable.

  OFFERING PRICE--The offering price of a share of a mutual fund is the price
at which the share is sold to the public.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Keystone Quality Bond Fund (B-1) (the "Fund") is a Pennsylvania common law
trust for which Keystone Management, Inc. ("KMI") is the Investment Manager
and Keystone Investment Management Company ("Keystone") is the Investment
Adviser. Keystone is a wholly-owned subsidiary of Keystone Investments, Inc.
("KII") and KMI is, in turn, a wholly-owned subsidiary of Keystone. The Fund
is registered under the Investment Company Act of 1940, as amended (the "1940
Act"), as a diversified, open-end investment company. The Fund seeks the
highest possible income consistent with preservation of principal. The Fund
invests primarily in high and investment grade corporate bonds, which possess
a high degree of dependability of interest and principal payments.

  The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles,
which require management to make estimates and assumptions that affect
amounts reported herein. Although actual results could differ from these
estimates, any such differences are expected to be immaterial to the net
assets of the Fund.

A. Valuation of Securities

U.S. Government obligations held by the Fund are valued at the mean between
the over-the-counter bid and asked prices, as furnished by an independent
pricing service. Listed corporate bonds, other fixed income securities,
mortgage and other asset-backed securities, and other related securities are
valued at prices provided by an independent pricing service. In determining
value for normal institutional-size transactions, the pricing service uses
methods based on market transactions for comparable securities and various
relationships between securities that are generally recognized by
institutional traders. Securities for which valuations are not available from
an independent pricing service (including restricted securities) are valued
at fair value as determined in good faith according to procedures established
by the Board of Trustees.

  Short-term investments with remaining maturities of 60 days or less are
carried at amortized cost, which approximates market value. Short-term
securities with greater than 60 days to maturity are valued at market value.

B. Repurchase Agreements

Pursuant to an exemptive order issued by the Securities
and Exchange Commission, the Fund, along with certain other Keystone funds,
may transfer uninvested cash balances into a joint trading account. These
balances are invested in one or more repurchase agreements that are fully
collateralized by U.S. Treasury and/or Federal Agency obligations.

  Securities pledged as collateral for repurchase agreements are held by the
custodian on the Fund's behalf. The Fund monitors the adequacy of the
collateral daily and will require the seller to provide additional collateral
in the event the market value of the securities pledged falls below the
carrying value of the repurchase agreement.

C. Reverse Repurchase Agreements

The Fund enters into reverse repurchase agreements with qualified third-party
broker-dealers. Interest on the value of reverse repurchase agreements is
based upon competitive market rates at the time of issuance. At the time the
Fund enters into a reverse repurchase agreement, it will establish and
maintain a segregated account with its custodian containing liquid assets
having a value not less than the repurchase price (including accrued
interest). If the counterparty to the transaction is rendered insolvent, the
ultimate realiza-

<PAGE>

PAGE 18
- --------------------------------
Keystone Quality Bond Fund (B-1)

tion of the securities to be repurchased by the Fund may be delayed or
limited.

D. Foreign Currency

The books and records of the Fund are maintained in United States (U.S.)
dollars. Foreign currency amounts are translated into United States dollars
as follows: market value of investments, assets and liabilities at the daily
rate of exchange; purchases and sales of investments, income and expenses at
the rate of exchange prevailing on the respective dates of such transactions.
Net unrealized foreign exchange gain (loss) resulting from changes in foreign
currency exchange rates is a component of net unrealized appreciation
(depreciation) on investments and foreign currency transactions. Net realized
foreign currency gains and losses resulting from changes in exchange rates
include foreign currency gains and losses between trade date and settlement
date on investment securities transactions, foreign currency transactions and
the difference between the amounts of interest and dividends recorded on the
books of the Fund and the amount actually 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
realized gain (loss) on foreign currency transactions.

E. Futures Contracts

In order to gain exposure to or protect against changes in security values,
the Fund may buy and sell futures contracts.

  The initial margin deposited with a broker when entering into a futures
transaction is subsequently adjusted by daily payments or receipts as the
value of the contract changes. Such changes are recorded as unrealized gains
or losses. Realized gains or losses are recognized upon closing the contract.

  Risks of entering into futures contracts include (i) the possibility of an
illiquid market for the contract, (ii) the possibility that a change in value of
the contract may not correlate with changes in the value of the underlying
instrument or index, and (iii) the credit risk that the other party will not
fulfill their obligations under the contract. Futures contracts also involve
elements of market risk in excess of the amount reflected in the statement of
assets and liabilities.

F. Forward Foreign Currency Exchange Contracts

The Fund may enter into forward foreign currency exchange contracts ("forward
contracts") to settle portfolio
purchases and sales of securities denominated in a foreign currency and to
hedge certain foreign currency assets or liabilities. Forward contracts are
recorded at the forward rate and are marked-to-market daily. Realized gains
and losses arising from such transactions are included in net realized gain
(loss) on foreign currency related transactions. The Fund bears the risk of
an unfavorable change in the foreign currency exchange rate underlying the
forward contract and is subject to the credit risk that the other party will
not fulfill their obligations under the contract. Forward contracts involve
elements of market risk in excess of the amount reflected in the statement of
assets and liabilities.

G. Security Transactions and Investment Income

Securities transactions are accounted for no later than one business day
after the trade date. Realized gains and losses are computed on the
identified cost basis. Interest income is recorded on the accrual basis and
includes amortization of discounts.

H. Federal Income Taxes

The Fund has qualified and intends to qualify in the future as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code"). Thus, the Fund is relieved of any federal income tax liability by
distributing all of its net tax-

<PAGE>

PAGE 19
- --------------------------------

able investment income and net taxable capital gains, if any, to its
shareholders. The Fund also intends to avoid excise tax liability by making
the required distributions under the Code. Accordingly, no provision for
federal income tax is required.

I. Distributions

The Fund distributes net investment income monthly and net capital gains, if
any, at least annually. Distributions to shareholders are recorded at the
close of business on the ex-dividend date.

  Income and capital gains distributions to shareholders are determined in
accordance with income tax regulations which may differ from generally
accepted accounting principles. These differences are primarily due to
differing treatment for paydown gains (losses) and foreign currency
transactions.

2. Capital Share Transactions

The Fund's Trust Agreement, as amended and restored, authorizes the issuance
of an unlimited number of shares of beneficial interest with a par value of
$1.00. Transactions in shares of the Fund were as follows:

                                     Year ended October 31,
                                      1996            1995

Shares issued in reinvestment
 of dividends and
 distributions                        581,588         799,017
- -------------------------------------------------------------
Net decrease                       (5,093,154)     (2,509,178)
=============================================================

3. Securities Transactions

Cost of purchases and proceeds from sales of investment securities (excluding
short-term securities) for the year ended October 31, 1996 were as follows:

                          Cost of         Proceeds
                         Purchases       from Sales
- ----------------------------------------------------
Non-U.S. Government     $309,095,323    $255,751,880
U.S. Government          282,174,491     402,430,535
====================================================

  The average daily balance of reverse repurchase agreements outstanding
during the year ended October 31, 1996 was approximately $7,133,000 at a
weighted average interest rate of 3.65%. The maximum amount of borrowing
during the year was $17,694,856 (including accrued interest).

  As of October 31, 1996, the Fund has a capital loss carryover for federal
income tax purposes of approximately $30,627,000 which expires as follows:
$2,251,000--1998; $20,145,000--2002; $6,153,000--2003; and $2,078,000--2004.

4. Distribution Plan

The Fund bears some of the costs of selling its shares under a Distribution
Plan (the "Plan") adopted pursuant to Rule 12b-1 under the 1940 Act. Under
the Plan, the Fund pays its principal underwriter, Keystone Investment
Distributors Company ("KIDC"), a wholly-owned subsidiary of Keystone, amounts
which are calculated and paid daily.

  Under the Plan, the Fund pays a distribution fee amount which may not exceed
1.00% of the Fund's average daily net assets. Of that amount, 0.75% is used
to pay distribution expenses and 0.25% may be used to pay service fees.

  Contingent deferred sales charges paid by redeeming shareholders may be paid
to KIDC.

  The Plan may be terminated at any time by vote of the Independent Trustees
or by vote of a majority of the outstanding voting shares of the Fund.
However,

<PAGE>

PAGE 20
- --------------------------------
Keystone Quality Bond Fund (B-1)

after the termination of the Plan, at the discretion of the Board of
Trustees, payments to KIDC may continue as compensation for its services
which had been earned while the Plan was in effect.

  KIDC intends, but is not obligated, to continue to pay distribution costs
that exceed the current annual payments from the Fund. KIDC intends to seek
full payment of such distribution costs from the Fund at such time in the
future as, and to the extent that, payment thereof by the Fund would be
within permitted limits.

  Total unpaid distribution costs at October 31, 1996 amounted to $9,151,321.

5. Investment Management Agreement and Other Affiliated Transactions

Under the terms of the Investment Management Agreement between KMI and the
Fund, KMI provides investment management and administrative services to the
Fund. In return, KMI is paid a management fee, computed and paid daily, at an
annual rate of 2.00% of the Fund's gross investment income plus an amount
determined by applying percentage rates starting at 0.50% and declining as
net assets increase to 0.25% per annum, to the average daily net asset value
of the Fund.

  KMI has entered into an Investment Advisory Agreement with Keystone under
which Keystone provides investment advisory and management services to the
