Keystone Mid-Cap Growth Fund (S-3) 
Seeks growth of capital from mid-cap stocks. 

Dear Shareholder: 

We are writing to report to you on the performance of Keystone Mid-Cap Growth 
Fund (S-3) for the twelve-month period which ended August 31, 1996. Following 
our letter we have included a discussion with your Fund's manager and 
Complete financial information. 

Performance 

For the twelve-month period, your Fund produced a return of 10.07%, which 
nearly matched the 11.87% return of its benchmark, the Standard & Poor's 400 
Mid-Cap Index. 

  These returns reflect the positive performance of the markets and our 
careful stock selection during the twelve-month period. Your Fund's returns 
were particularly attractive during the first nine months of the period when 
mid-cap growth stocks recorded strong performance. 

  The market was led by stocks of large, high quality companies. Strong 
corporate earnings, relatively low interest rates, and controlled inflation 
sent stocks to new highs in 1996. However, concerns over the sustainability 
of earnings growth rates in a higher interest rate environment mounted in the 
Spring of 1996. Stocks declined in response during June and July, with small 
and medium market capitalization issues experiencing steeper declines than 
large-cap issues. The declines were short-lived, as indications of slower 
economic growth appeared and stocks rallied in August and September. Although 
selected stocks recovered, this was a period of readjustment for some mid-cap 
stocks. 

Individual stock selection 

In selecting stocks for the portfolio, we seek high-quality medium-sized 
companies that we believe have attractive and consistent earnings growth 
rates. We attempt to identify businesses with well-established products, 
services and management teams. Many of these companies are still in the 
accelerated growth phase of their life cycle and offer the potential for 
continued strong growth. By investing in mid-cap growth stocks, your Fund 
seeks to offer greater growth potential than investing solely in large 
company stocks, and more consistent performance than investing only in small 
company stocks. 

Our outlook 

We are expecting the favorable economic fundamentals of 1996 to continue into 
1997. However, the stronger-than-expected economic growth of the first half 
of 1996 has already begun to show signs of slowing to more moderate levels. 
Inflation should remain under control, despite some wage pressures, which 
should allow interest rates to remain relatively stable. 

  For investors with long-term goals, we continue to believe that stocks offer 
the best potential returns. However, we are now in the sixth year of a stock 
market rally--the longest since the end of World War II. While we have a 
favorable outlook for next year, history has shown that strong performance 
does not persist indefinitely. Stocks periodically experience price declines. 
We witnessed this type of "correction" in June and July, followed by a 
recovery in August. With this in mind, we encourage you to keep the above 
average stock market returns of the last few years in perspective. 


  We are pleased to inform you that Keystone has agreed to be acquired by 
First Union Corporation. The acquisition is subject to a number of 
conditions, including approvals of investment advisory agreements with 
Keystone 
                                --Continued--

by fund shareholders. 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 $140 billion. First Union, through its 
wholly-owned subsidiary Evergreen Asset Management Corp., manages more than 
$16 billion in 36 mutual funds. Keystone will remain a separate entity after 
its acquisition and will continue to provide investment advisory and 
management services to the Fund. We believe First Union's acquisition of 
Keystone should strengthen the investment management services we provide to 
you. 

  We appreciate your continued support of Keystone Mid-Cap Growth Fund (S-3). 
If you have any questions or comments about your investment, please feel free

                              A Discussion With 
                              Your Fund Manager 

                         (Photo of Margery C. Parker)

             Margery C. Parker is portfolio manager of your Fund and 
         Keystone Global Opportunities Fund. Ms. Parker has more than 
         15 years of investment management experience. She holds a BA 
            from Wellesley College and an MBA from Babson College. 
          Together with senior portfolio manager Maureen Cullinane, 
      head of Keystone's growth stock group, she selects mid-cap stocks 
                                for your Fund. 

Q   What was the economic environment like? 

A  This was a favorable environment for medium market capitalization 
(mid-cap) stocks for most of the twelve-month period. At the end of 1995, 
economic growth was moderate, inflation was contained, and interest rates had 
declined. At the beginning of 1996, this environment changed. While stock 
prices generally rose, they fluctuated broadly during the period as virtually 
every new economic report triggered a debate over growth and inflation and 
whether or not the Federal Reserve Board would raise interest rates. 

Q   In relation to other types of stocks, how did mid-cap stocks perform? 

A  Mid-cap stocks provided attractive returns, but lagged the large-cap 
Standard and Poor's 500 Index (S&P 500) for the twelve-month period which 
ended August 31, 1996. However, we believe that mid-cap stocks have greater 
growth potential than many large-cap stocks. In addition, mid-cap stocks 
generally do not carry the risks and price volatility associated with 
small-cap stocks, which experienced sharp price declines this summer. This 
correction effected most all stocks, and we believe it helped to wring out 
the excesses of the market, bringing stock prices down to more reasonable 
levels. 

Q   What is the attraction of mid-cap stocks for investors? 

A  In a few words: attractive growth with lower price volatility. 
Historically, mid-capitalization stocks have tended to exhibit higher growth 
rates than larger-cap stocks, such as those in the S&P 500. They also 
generally have provided more consistent earnings than smaller companies. We 
define mid-cap as stocks of companies with market capitalizations generally 
between $750 million and $3 billion. A stock's market capitalization is 
determined by multiplying its current price by the number of shares 
outstanding.

Keystone Mid-Cap Growth Fund (S-3)

Your Fund Invests In . . . 
(bullet) Dynamic companies with earnings growth rates of 20% or more 
(bullet) Companies with strong management, a leading market position, and a 
         solid balance sheet 
(bullet) Primarily medium-sized companies with market capitalizations between 
         $750 million and $3 billion 
(bullet) U.S. stocks and stocks of established foreign companies 

Q   How do you decide where to invest? 

A  In managing your Fund, we pursue a disciplined approach to investing that 
begins with a detailed analysis of the economy, industry trends and the 
business cycle. We consider the effects of economic growth, interest rates, 
stock price changes and other measures in our evaluation. Through this 
process, we seek to uncover attractive areas for further investigation. 

  We then conduct individual company research, focusing on a company's 
management, financials, product line, and potential to grow earnings at 20% 
or more a year. We seek to invest in a diverse group of companies that have a 
strong earnings growth records. We conduct extensive analysis on the 
company's financial condition including projections for earnings, profits, 
and revenues. We also believe it is important to be in frequent contact with 
company managements to determine if the company will live up to our 
expectations. 

Q   What companies were you attracted to during the twelve-month period? 

A  We emphasized a number of companies that fell into the category of 
business services. These companies accounted for 12.9% of net assets as of 
August 31, 1996. This is not an economic sector, per se. It is a group of 
unique companies with specialized products and services. These companies 
often have limited competition and are less dependent on the direction of the 
economy than other types of businesses. Typically these companies expand 
their business through aggressive selling, opening new geographical 
territories, or by acquiring smaller firms. This is an eclectic group. One 
example is G&K Services, a company that supplies uniforms to a number of 
businesses in the Midwest. Uniform companies tend to be small "mom and pop" 
operations, and G&K is expanding its business by purchasing some of these 
smaller concerns. 

Q   Energy services companies represented 5.2% of net assets on August 31, 
1996. What was attractive here? 

A  Energy services companies, which are listed as 'oil services' in the 
Schedule of Investments beginning on page 9, support the drilling activities 
of the energy industry. They may supply oil rigs, tool bits, boats, pumping 
equipment or seismology services. Many of these companies undertook major 
restructuring programs over the last several years. Their managements have 
become more aggressive and they have increased productivity. In addition, 
demand for their expertise has increased. This is because, after several 
years of overcapacity, demand for energy has increased. In order to rebuild 
inventories, the major oil companies have been enlisting the help of energy 
services firms. Some of these companies we held in the portfolio include 
Diamond Offshore, BJ Services, and Tidewater.

Q   The financial sector has been an important part of the portfolio for 
several years. What did you find attractive among financial stocks? 

A  Many of these companies have been benefitting from a consolidation in the 
industry. Banks in particular are attempting to lower internal costs, expand 
their franchises, and to reach a size where they can be more competitive in a 
deregulated environment. One way that many financial institutions are 
accomplishing this is through mergers with or acquisitions of other financial 
institutions. 

  We have maintained many of the same financial stocks in the portfolio over 
the twelve-month period. As of August 31, 1996, these holdings represented 
10.7% of net assets. In the Northeast, Bank of Boston acquired BayBank and 
South Boston Savings Bank. Washington Mutual, a bank in Washington state 
recently acquired a financial institution in California. With this 
acquisition, Washington Mutual expanded into a new market. TCF Financial, a 
Midwestern bank, has carved out a niche market for itself. It caters to 
customers at the lower end of the retail banking market. Through an extensive 
branch network, TCF provides a complete spectrum of financial services, 
including checking accounts, savings accounts, mortgages, and investment 
services. Another company that has benefitted from the growth in the 
financial services industry is BISYS Group. As an outsourcing provider, BISYS 
supplies financial services firms with transaction processing, recordkeeping, 
and other administrative services. 

Q   Retail stocks were among the Fund's top industry sectors. After several 
years in the doldrums, did retail stocks come into favor? 

A  It has been a mixed bag for retailers. However, we have continued to focus 
on individual specialty retailers that we believe have had solid financial 
results and good growth rates. At 8.2% of net assets as of August 31, 1996, 
retailers were the Fund's third largest industry weighting. Two companies we 
found particularly attractive were PETsMART, a top ten holding, and Kohls. 
PETsMART is a national pet supply chain of superstores. It is expanding its 
business to include veterinary services and equine products and services. We 
believe PETsMART has the potential to continue its rapid growth rate. Kohls 
is a high quality Midwest department store. It is planning an expansion into 
the Northeast. 

Q   What is your outlook for mid-cap stocks? 

A  We believe the combination of moderate economic growth and relatively low 
interest rates and inflation should continue to provide a positive investment 
environment for growth stocks. In the months ahead, we will continue to stay 
with our investment strategy of searching for high quality growth companies 
that we believe can provide the Fund with capital appreciation over the long 
term.

There is no sales charge when you buy Fund shares. The Fund currently imposes 
a contingent deferred sales charge that declines from 4% to 1% if you redeem 
shares within four years of purchase. The one- year return reflects the 
deduction of the 3% contingent deferred sales charge for those investors who 
sold Fund shares after one calendar year. Investors who retained their fund 
investment received the one-year return reported in the second column of the 
table.

This chart graphically compares your Fund's total return 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 Mid-Cap Growth Fund (S-3) 

The Fund seeks growth of capital from mid-cap stocks. The return is quoted 
after deducting sales charges (if applicable), fund expenses and transaction 
costs and assumes reinvestment of all distributions. 

2. Standard & Poor's 400 MidCap Index (S&P 400) 

The S&P 400 is a broad-based unmanaged index of common stock prices. The 
index is comprised of stocks of medium-sized U.S. companies. The average 
market capitalization of the index is $2.8 billion with stocks ranging from 
approximately $200 million to $6.5 billion. 

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. Stocks that 
comprise S&P indexes are selected and compiled by Standard & Poor's 
Corporation according to criteria that may be unrelated to your Fund's 
investment objective. It would be difficult for most individual investors to 
duplicate these indexes. 

Understanding what the chart means 

  The chart demonstrates your Fund's total return 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 can help you 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.

NOTES TO FINANCIAL STATEMENTS 

(1.) Significant Accounting Policies 

Keystone Mid-Cap Growth Fund (S-3) (the "Fund") is a 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's investment 
objective is to provide shareholders with growth of capital. 

  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 

Investments are usually valued at the closing sales price or, in the absence 
of sales and for over-the-counter securities, the mean of the bid and asked 
prices. 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. Foreign Currency 

The books and records of the Fund are maintained in United States ("U.S.") 
dollars. Foreign currency amounts are translated into U.S. 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 sub- 

<PAGE>

- ----------------------------------------------------------------------------- 
Keystone Mid-Cap Growth Fund (S-3) 

sequent sale trade date is included in realized gain (loss) on foreign 
currency transactions. 

D. 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 and premiums. Dividend income is recorded 
on the ex-dividend date. 

E. 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 taxable 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. 

F. Distributions 

The Fund distributes net investment income 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 of short-term gains. 

(2.) Capital Share Transactions 

The Fund's Declaration of Trust 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:

(3.) Securities Transactions 

Cost of purchases and proceeds from sales of investment securities (excluding 
short-term securities) for the year ended August 31, 1996, were $434,199,796 
and $477,408,817, respectively. 

(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. During the year ended August 31, 1996, the Fund received $54,272 in 
contingent deferred sales charges. 


  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, after the termination of the Plan, at the discretion of the Board of 
Trustees, payments to KIDC may con-

tinue 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. 

(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, 
determined by applying percentage rates starting at 0.70% and declining as 
net assets increase to 0.35% 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 
Fund. In return for its services, Keystone receives an annual fee equal to 
85% of the management fee received by KMI. 

  During the year ended August 31, 1996, the Fund paid or accrued $24,767 to 
Keystone for certain accounting services. The Fund paid or accrued $711,550 
to Keystone Investor Resource Center, Inc., a wholly-owned subsidiary of 
Keystone, for services rendered as the Fund's transfer and dividend 
disbursing agent. 

  Certain officers and/or Directors of Keystone are also officers and/or 
Trustees of the Fund. Officers of Keystone and affiliated Trustees receive no 
compensation directly from the Fund. 

(6.) Expense Offset Arrangement 

The Fund has entered into an expense offset arrangement with its custodian. 
For the year ended August 31, 1996, the Fund incurred total custody fees of 
$189,739 and received a credit of $24,378 pursuant to this expense offset 
arrangement, resulting in a net custody expense of $165,361. The assets 
deposited with the custodian under this expense offset arrangement could have 
been invested in income-producing assets. 

(7.) Subsequent Event 

On September 6, 1996, Keystone Investments, Inc. entered into an Agreement 
and Plan of Acquisition and Merger (the "Acquisition") with First Union 
Corporation and First Union National Bank of North Carolina ("First Union") 
whereby First Union would acquire all the assets and liabilities of Keystone 
Investments, Inc. in exchange for shares of First Union. Subject to the 
receipt of the required regulatory and shareholder approvals, the Acquisition 
is expected to take place in late December 1996.

INDEPENDENT AUDITORS' REPORT 

The Trustees and Shareholders 
Keystone Mid-Cap Growth Fund (S-3) 

We have audited the accompanying statement of assets and liabilities of 
Keystone Mid-Cap Growth Fund (S-3), including the schedule of investments, as 
of August 31, 1996, and the related statement of operations for the year then 
ended, the statements of changes in net assets for each of the years in the 
two-year period then ended, and the financial highlights for each of the 
years in the ten-year period then ended. These financial statements and 
financial highlights are the responsibility of the Fund's management. Our 
responsibility is to express an opinion on these financial statements and 
financial highlights based on our audits. 

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements and 
financial highlights are free of material misstatement. An audit includes 
examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements. Our procedures included confirmation of 
securities owned as of August 31, 1996 by correspondence with the custodian 
and brokers. An audit also includes assessing the accounting principles used 
and significant estimates made by management, as well as evaluating the 
overall financial statement presentation. We believe that our audits provide 
a reasonable basis for our opinion. 

In our opinion, the financial statements and financial highlights referred to 
above present fairly, in all material respects, the financial position of 
Keystone Mid-Cap Growth Fund (S-3), as of August 31, 1996, the results of its 
operations for the year then ended, the changes in its net assets for each of 
the years in the two-year period then ended, and the financial highlights for 
each of the years in the ten-year period then ended, in conformity with 
generally accepted accounting principles.

FEDERAL TAX STATUS--FISCAL 1996 DISTRIBUTIONS (Unaudited) 

  During the fiscal year ended August 31, 1996, distributions of $0.92 per 
share were paid in shares or cash. This total includes a taxable long-term 
capital gain distribution of $0.33 per share. The remaining $0.59 per share 
is short-term capital gains taxable to shareholders as ordinary income in the 
year in which received by them or credited to their accounts. Of the ordinary 
income distributions, 36% is eligible for the corporate dividend received 
deduction. 

  The above figures may differ from those cited elsewhere in this report due 
to differences in the calculation of income and capital gains for accounting 
(book) purposes and Internal Revenue Service (tax) purposes. 

  In January 1997, we will send you complete information on the distributions 
paid during the calendar year 1996 to help you in completing your federal tax
