INVESTMENT OBJECTIVE AND POLICIES
 
  The Fund's objective is to provide its shareholders with a diversified holding
of  securities which appear to offer  marked possibilities for long-term capital
appreciation. It is expected that common stocks will continue to be the  primary
emphasis  in  the portfolio.  Preference is  given to  holdings in  high quality
companies characterized by reasonably predictable earnings, above average return
on equity, market dominance  and financial strength.  Because we recognize  that
smaller  capitalization companies  provide somewhat  higher returns  over longer
time frames,  some  emphasis is  placed  on  small to  medium  sized  companies,
generally  located  in  our  geographic  region,  that  may  be  under  owned by
institutional investors. Assets of the Fund will be reasonably fully invested at
all times. Cash, bank certificates of deposit and short-term debt securities may
be held in modest amounts  to provide a reserve  for future purchases or  better
enable  the Fund to achieve its objective.  Portfolio turnover is expected to be
modest in relation to comparable mutual funds.
 
  A detailed description of  the Fund's investment  limitations is contained  in
the  Statement  of  Additional  Information.  Such  limitations  are fundamental
policies which  cannot be  changed without  the approval  of a  majority of  the
Fund's  shareholders, as defined in the Statement of Additional Information. The
Fund will not invest in oil, gas or other mineral leases and real estate limited
partnership interests.
 
MANAGEMENT OF THE FUND
 
  The Board  of Directors  has overall  responsibility for  the Fund.  The  Fund
employs  Mairs  and  Power,  Inc.,  W-2062  First  National  Bank  Building, 332
Minnesota Street, St.  Paul, Minnesota  55101, to manage  the Fund's  investment
portfolio  and certain other business affairs  under a contract that compensates
Mairs and Power, Inc. at the rate of one-twentieth of one percent of the  Fund's
month-end  net asset value (0.6% annually),  computed and paid each month. Mairs
and Power, Inc. has managed mutual funds since 1958 and has provided  investment
counsel services in St. Paul since 1931.
 
  George  A.  Mairs,  III,  President  of Mairs  and  Power,  Inc.  is primarily
responsible for the day-to-day management of the Fund's portfolio. Mr. Mairs has
been an officer and director of Mairs and Power, Inc. since 1961.
 
  Mairs and  Power,  Inc.  acts  as  the  Fund's  Transfer  Agent  and  Dividend
Disbursing  Agent  and  is  reimbursed  for  all  expenditures  incurred  in the
discharge of these duties. The  ratio of the transfer  agent fee to average  net
assets in 1995 was 0.11%.
 
  Norwest  Bank Minnesota, N. A. acts as  Custodian for the Fund pursuant to the
terms of a custodial agreement which must  be approved annually by the Board  of
Directors.  It controls all securities and cash  for the Fund, receives and pays
for securities purchased, delivers against payment for securities sold, receives
and collects income from investments, makes  all payments for Fund expenses  and
performs other administrative services, all as directed in writing by authorized
officers  of the Fund. The  ratio of the custodial fee  to average net assets in
1995 was 0.07%.
 
  Effective May 1, 1996 Firstar Trust  Company of Milwaukee, Wisconsin will  act
as  Transfer Agent,  Dividend Disbursing Agent  and Custodian for  the Fund, and
will assume all duties, responsibilities and control of these functions pursuant
to the same terms set forth above.
 
  The ratio of the management  fee to average net assets  in 1995 was 0.6%;  the
ratio  of total Fund operating expenses  to average net assets ("expense ratio")
was 0.99%. Mairs and Power, Inc. has agreed with the Fund that the expense ratio
will not exceed the lowest expense limitation  of any state in which the  Fund's
shares are sold.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
 
1995 IN REVIEW
 
  1995  was a superb year for Mairs and Power Growth Fund shareholders. The Fund
showed a 49.3%  return for the  year after adjustment  for reinvestment of  cash
dividends  and  capital gain  distributions. This  compares very  favorably with
returns of 36.9% for the Dow Jones Industrial Average and 37.5% for the Standard
& Poor's 500 Stock Index. The  Fund also substantially outperformed the  average
domestic  stock fund which had  a 31.1% return for  the year according to Lipper
Analytical Services.
 
  Stocks had a spectacular performance in  1995 and the Standard and Poor's  500
Stock  Index registered its strongest gain  since 1958. Three positive surprises
during the year contributed to the performance. First, long term interest  rates
were   expected  to  remain   steady  during  the   year  but  instead  declined
significantly, resulting in a sharp rise  in the bond market. Second,  corporate
earnings  were stronger  than anticipated with  earnings for the  S&P 500 rising
about 16%. Finally, investors became more hopeful that fiscal policy was  moving
in  a more  conservative direction  which would  restrain future  inflation. The
federal deficit declined to 2.3% of GDP in fiscal 1995, down from 4.9% in  1992.
Furthermore,  virtually all Washington  policy-makers now recognize  the need to
slow the rise in federal spending and further reduce the federal deficit.

THE FUND
 
  The  Fund  is  an  open-ended,   diversified  management  company  which   was
incorporated  in Minnesota  in 1958.  The fund  has authorized  capital stock of
10,000,000 shares, $0.01 par value per share. Each share entitles the holder  to
one  vote at  all meetings  of Fund shareholders  and to  participate equally in
dividends and  distributions declared  by the  Fund, and  in its  remaining  net
assets on liquidation after satisfaction of
 
                                       5
<PAGE>
outstanding  liabilities.  Fund shares  are fully  paid and  non-assessable when
issued, have  no  preemptive,  conversion,  or  cumulative  voting  rights,  are
transferable without restrictions and are redeemable at net asset value.
 
PURCHASING SHARES
 
  Shares  of the Fund may be purchased, with no sales charge, from Firstar Trust
Company, the Fund's Custodian  and Transfer Agent. The  price per share will  be
the  net asset value next computed after  the time the application and funds are
received in proper order by the  Transfer Agent. The determination of net  asset
value for a particular day is applicable to all applications for the purchase of
shares received at or before the close of trading on the New York Stock Exchange
(the  "Exchange") on  that day  (usually 3:00  p.m. Central  time). Accordingly,
purchase orders received on a day the exchange is open for trading, prior to the
close of trading on that day, will be valued as of the close of trading on  that
day.  Applications for  purchase of  shares after  the close  of trading  on the
exchange will be based upon the net asset value as determined as of the close of
trading on the next day the exchange is open.
 
  An initial purchase must be at least $2,500 and each subsequent purchase  must
be  at least $100, although the Fund reserves the right to waive or change these
minimums at  its discretion.  All  applications to  purchase capital  stock  are
subject  to acceptance or rejection  by authorized officers of  the Fund and are
not binding until accepted. Applications will not be accepted unless accompanied
by payment in U.S. funds. Payment should be made by check drawn on a U.S.  bank,
savings  and loan, or credit union. The Fund  will not accept payment in cash or
third party checks for the purchase of shares.
 
  The custodian  will charge  a  $20 fee  against  a shareholder's  account,  in
addition  to any loss sustained  by the Fund, for  any payment check returned to
the custodian for insufficient funds. It is the policy of the Fund not to accept
applications under  circumstances or  in amounts  considered disadvantageous  to
shareholders;  for example, if an individual previously tried to purchase shares
with a bad  check, or the  proper social security  number or tax  identification
number is omitted, the Fund reserves the right not to accept future applications
from  such individual.  The Fund  reserves the  right to  reject any application
which does not include a certified social security or tax identification number.
 
  Stock certificates will not ordinarily be issued unless the investor  requests
a  certificate in writing. The Fund will invest the entire dollar amount of each
purchase order  in  full  and  fractional  Fund  shares  and,  unless  otherwise
instructed,  will reinvest all income  dividends and capital gains distributions
in additional full and fractional  shares. Investors may, however, request  that
income dividends and/or capital gains distributions be paid in cash.
 
  The  Fund  does not  consider  the U.S.  Postal  Service or  other independent
delivery services to be its agents. Therefore, deposit in the mail or with  such
services,   or  receipt  at  the  Custodian's   post  office  box,  of  purchase
applications does not constitute receipt by the Custodian or the Fund.

REDEEMING SHARES
 
  Shareholders  may  redeem  for  cash  all or  a  portion  of  their  shares by
instructing the Fund's  Transfer Agent  at its office  in Milwaukee,  Wisconsin.
Shares  will be redeemed at the net  asset value next computed after the receipt
of a redemption request and accepted by the Fund. The determination of net asset
value for a particular day is applicable  to all requests for the redemption  of
shares received at or before the close of trading on the New York Stock Exchange
(the "Exchange") on that day (usually 3:00 p.m. Central time). Requests received
for  redemption on a day the exchange is open for trading, prior to the close of
trading on that  day, will be  valued as of  the close of  trading on that  day.
Requests  for redemption of  shares received after  the close of  trading on the
exchange will be based upon the net asset value as determined as of the close of
trading on the next day  the exchange is open. A  redemption request must be  in
"good  order" before the proceeds can be released. This means the following will
be required:
 
(a) A letter of instruction or a stock assignment specifying the account number,
    number of shares or dollar  amount to be redeemed,  signed by all owners  of
    the  shares exactly as their names appear in the Fund's shareholder records.
    If certificates have been  issued representing shares  to be redeemed,  they
    must accompany the letter.
 
(b)  A  guarantee  of the  signature  of  each owner  by  an  eligible signature
    guarantor such as a  U.S. commercial bank, trust  company, or member of  the
    New York Stock Exchange for redemption requests greater than $10,000.
 
(c)  In the case of estates, trusts, guardianships, custodianships, corporations
    and pension and profit-sharing plans,  other supporting legal documents  may
    be required.
 
(d)  A  guarantee  of the  signature  of  each owner  by  an  eligible signature
    guarantor such as a  U.S. commercial bank, trust  company, or member of  the
    New  York Stock Exchange, if  the address of record  has been changed within
    the 15 days preceding any liquidation.
 
  If the proceeds of any redemption are requested to be made payable to or  sent
to  other than the  address of record,  the signature(s) on  the request must be
guaranteed by an eligible signature guarantor  such as a commercial bank,  trust
company, or a member of the New York Stock Exchange.
 
  If  any portion of the shares to  be redeemed represents an investment made by
check, the  Fund may  delay the  payment of  the redemption  proceeds until  the
transfer  agent is reasonably satisfied that the check has been collected, which
may take up to twelve days from the purchase date.
 
  Payment for shares redeemed will be mailed to you typically within one or  two
business  days, but no later than the  seventh business day after receipt by the
Transfer Agent of the redemption request  in good order, or within such  shorter
period  as may legally be required. If  payment of liquidation proceeds is to be
made by Fed wire transfer, a $10 wire fee will be applied.
 
                                       7
<PAGE>
  The Fund may  be required  to withhold  federal income tax  at a  rate of  31%
(backup  withholding)  from  dividend  payments,  distributions,  and redemption
proceeds if a  share-holder fails to  furnish the  Fund with his  or her  social
security  or tax identification  number. The shareholder  also must certify that
the number is correct and that he  or she is not subject to backup  withholding.
The certification is included as part of the share purchase application form. If
the  shareholder  does not  have  a social  security  number, he  or  she should
indicate on the purchase form that an application to obtain a number is pending.
The Fund is required to withhold taxes if a number is not delivered to the  Fund
within seven days.
 
  No  redemption request  will become  effective until  all documents  have been
received in proper form  by the Transfer Agent.  The shareholder should  contact
the Transfer Agent for further information concerning documentation required for
a redemption of Fund shares.
 
  Shareholders  who have an IRA or other  retirement plan must indicate on their
redemption request whether  or not  to withhold federal  income tax.  Redemption
requests  failing  to indicate  an election  not  to have  tax withheld  will be
subject to withholding.
 
  The right  of redemption  may  be suspended  or the  date  of payment  may  be
postponed  (1) during weekend or holiday closings, or when trading is restricted
as determined by the Securities and Exchange Commission ("SEC"), (2) during  any
period when an emergency exists as determined by the SEC as a result of which it
is  not reasonably practicable for the Fund to dispose of securities owned by it
or to fairly determine the value of its net assets, and (3) for such a period as
the SEC may permit.  A redemption order  may not be canceled  or revoked by  the
shareholder  once  it has  been received  and  accepted by  the Fund.  Since the
redemption price is the net  asset value per share  determined at the same  time
and  in  the same  manner as  for a  purchase  order received  at that  time, it
reflects the market value of the  Fund's investments at the time of  redemption.
This  value may be more  or less than the price  originally paid for the shares,
and the investor may realize a gain or loss on redemption.
 
DISTRIBUTIONS AND TAX CONSEQUENCES
 
  The Fund distributes all of its  net investment income to shareholders in  the
form  of semi-annual  dividends, normally in  June and December.  If net capital
gains are realized, the Fund will distribute  them near year-end in the year  in
which  such gains are realized.  The Fund intends to comply,  as it did in 1995,
with the special provisions  of Subchapter M of  the Internal Revenue Code  that
relieve  it from federal income  tax on net investment  income and capital gains
currently distributed to  shareholders. The Internal  Revenue Code requires  all
regulated  investment companies to pay a nondeductible 4% excise tax if at least
98% of ordinary income and 98% of capital gains are not paid out to shareholders
during the  year in  which they  are earned  or realized.  The Fund  intends  to
distribute  income and capital gains in such a manner as to avoid the imposition
of this excise tax.
 
  Fund shareholders will be subject to  federal income tax at ordinary rates  on
distributions  of investment income and  short-term capital gains. Distributions
of net long-term  capital gains are  taxable to Fund  shareholders as  long-term
capital  gain regardless  of the  length of  time shares  of the  Fund are held.
Short-term capital gains are taxed at the same rate as an individual's  ordinary
income;  long-term capital gains are  taxed at a maximum  rate of 28%. Dividends
and distributions will  be taxable  whether received  in cash  or reinvested  in
additional  shares of the Fund. Shareholders will  be advised annually as to the
source of distributions for tax purposes.  Distributions may also be subject  to
state  and local taxes.  Shareholders not subject  to tax on  income will not be
required to pay tax on amounts distributed from the Fund.
 
                                       8
<PAGE>
  The Fund's dividends and distributions are paid  on a per share basis. At  the
time  of such payment, therefore, the value of each share will be reduced by the
amount of the payment. If shares are  purchased shortly before the payment of  a
dividend or a capital gains distribution, purchasers will pay the full price for
the shares and then receive some portion of the price back as a taxable dividend
or distribution.
 
  The foregoing is a general summary of current federal income tax law regarding
the Fund. Investors should consult with their own tax adviser regarding federal,
state and local tax consequences of an investment in the Fund.
 
DETERMINING NET ASSET VALUE PER SHARE
 
  The net asset value per share for purchase and redemption orders is determined
once  daily, as  of the  close of regular  trading hours  on the  New York Stock
Exchange (currently 3:00  p.m., Central  time) on each  day the  New York  Stock
Exchange is open for trading. As a result, shares of the Fund will not be priced
on  the days which the  Exchange observes: New Years  Day, Presidents' Day, Good
Friday,  Memorial  Day,  Independence  Day,  Labor  Day,  Thanksgiving  Day  and
Christmas  Day. Net asset  value per share  is calculated by  dividing the total
market value of the Fund's investments  and other assets, less any  liabilities,
by the total outstanding shares of the Fund. Securities traded on one or more of
the  national securities  exchanges are  valued at  the last  sale price  on the
securities exchange on which such securities are primarily traded or at the last
sale price on the  national securities market.  For securities where  quotations
are not readily available, or where the last quoted sale price is not considered
representative  of the value of that security if it were to be sold on that day,
the security will be  valued at fair  value as determined in  good faith by  the
Adviser.
 
  The  Fund's  securities  may be  valued  based  on valuations  provided  by an
independent pricing service. These  valuations are reviewed  by the Adviser.  If
the  Adviser  believes  that a  valuation  received  from the  service  does not
represent a fair  value, it values  the security  by a method  that the  Adviser
believes will determine a fair value.

RISKS
 
  All investments have risks.  Although the Fund cannot  eliminate all risk,  it
seeks  to  moderate  risk by  investing  in a  diversified  portfolio. Long-term
investors, for  whom  the  Fund  is  designed,  should  be  prepared  to  accept
fluctuations  in portfolio  value as  the Fund  seeks to  achieve its investment
objective. There can be no assurance, of course, that the Fund will achieve  its
objective.

INVESTMENT OBJECTIVE AND POLICIES

    As discussed on page 4 of the Fund's Prospectus, the Fund will normally be
fully invested in common stocks that appear to offer marked possibilities for
long-term appreciation.

INVESTMENT LIMITATIONS

    The Fund is subject to the following restrictions which may not be changed
without the approval of a majority of the shareholders of the Fund.  The vote of
a majority of the shareholders means the vote, at the annual or a special
meeting of the security holders, of holders representing (a) 67% or more of the
voting securities present at such meeting, if the holders of more than 50% of
the outstanding voting securities are present or represented by proxy; or (b)
more than 50% of the outstanding voting securities, whichever is less.  The Fund
may not:

(1) Purchase securities of any issuer if as a result, (a) more than 5% of the
    value of the assets of the Fund would then be invested in the securities of
    a single issuer (other than U.S. Government obligations), or (b) more than
    10% of any class of securities, or more than 10% of the outstanding voting
    securities, of the issuer would then be held by the Fund;

(2) Purchase securities of other investment companies if as a result more than
    5% of the Fund's total assets would then be (a) invested in the securities
    of that investment company, or (b) more than 10% of the Fund's assets would
    then be invested in securities of all investment companies;

(3) Concentrate more than 20% of its investments in a particular industry;

(4) Purchase or sell real estate, real estate investment trusts, or other
    interests in real estate which are not readily marketable;

(5) Write, purchase or sell puts, calls, or combinations thereof;

(6) Make loans (although it may acquire portions of an issuer's publicly
    distributed securities);

(7) Purchase securities on margin or sell short;

(8) Borrow money, except that the Fund may borrow from banks up to 5% of its
    total assets to pay capital gains distributions, to pay income dividends,
    or to relieve an extraordinary or emergency situation, but not for
    investment purposes;

(9) Mortgage, pledge, hypothecate, or in any manner transfer, as security for
    indebtedness, any securities owned or held by the Fund;

(10) Participate on a joint or a joint and several basis in any trading account
    in securities;

(11) Invest in companies for the purpose of exercising control of management;

(12) Act as an underwriter of securities of other issuers;


                                          5

<PAGE>

(13) Purchase or retain the securities of any issuer if officers and directors
     of the Fund or its investment adviser who own individually more than
     one-half of one per cent of the securities of such issuer, together own
     more than 5% of the securities of such issuer;

(14) Purchase or sell commodities or commodity contracts in the ordinary course
     of its business;

(15) Purchase or sell "restricted securities" in such a way as to become an
     "underwriter" within the meaning of that term as used in the Securities Act
     of 1933.

PORTFOLIO TURNOVER

    The Fund anticipates that its annual portfolio turnover rate will not
exceed 50%.  The Fund, however, has not placed any limit on its rate of
portfolio turnover and securities may be sold without regard to the time they
have been held when in the opinion of the Investment Adviser investment
considerations warrant such action.  Portfolio turnover rate is calculated by
dividing the lesser of the Fund's annual sales or purchases of portfolio
securities (exclusive of securities with maturities of one year or less at the
time the Fund acquired them) by the monthly average value of the securities in
the Fund's portfolio during the year.

PURCHASING AND REDEEMING SHARES

    The purchase and redemption of Mairs and Power Growth Fund, Inc. shares are
subject to the procedures described on pages 6 and 7 of the Fund's Prospectus,
which is incorporated herein by reference.

PRINCIPAL HOLDERS OF SECURITIES

    As of March 31, 1996, there were no shareholders who held more than 5% of
the Fund's outstanding shares.

OFFICERS AND DIRECTORS

    The officers and directors of the Fund and their principal occupations for
the last five years are set forth below.  Unless otherwise noted, the address

except that Mr. Frels is President and Mr. Mairs is Secretary of that fund.

which makes recommendations to the Board regarding the selection of auditors and
confers with the auditors regarding the scope and results of the annual audit.
The Fund does not pay any remuneration to its


                                          7

officers and directors other than fees to Directors who are not officers,
directors, employees or holders of 5% or more of the outstanding voting
securities of the Fund's Investment Adviser, which totaled $14,850 in 1995.  As
of March 31, 1996, the directors and officers of the Fund, as a group, and their
spouses and minor children owned beneficially 63,397 shares, or 4.31% of the
Fund.

INVESTMENT ADVISER

     Mairs and Power, Inc., a Minnesota corporation, is the Investment Adviser
of the Fund.  Mairs and Power, Inc. shareholders, all of whom are officers and
directors of the Fund, along with their percentage ownership positions in Mairs
and Power, Inc., are listed below:

               George A. Mairs, III          54.9%
               William B. Frels              31.9%
               Peter G. Robb                 11.8%
               Kathleen M. Kellerman         1.4%

     Mairs and Power, Inc. has furnished continuous investment supervision to
the Fund since 1958.  Mairs and Power, Inc. currently provides similar services
to one other mutual fund, Mairs and Power Income Fund, Inc., net assets of which
as of December 31, 1995 were $16,978,753.

     Mairs and Power, Inc. serves as Investment Adviser to the Fund under the
terms of an Investment Advisory Agreement dated March 20, 1972.  The Investment
Advisory Agreement must be approved annually by the Board of Directors of the
Fund, including a majority of those directors who are not parties to such
contract or "interested persons" of any such party as defined in the Investment
Company Act of 1940, by vote cast in person at a meeting called for such
purpose.  The Agreement may be terminated at any time, without penalty, on sixty
days' written notice by the Fund's Board of Directors, by the holders of a
majority of the Fund's outstanding voting securities or by the Investment
Adviser.  The Agreement automatically terminates in the  event of its assignment
(as defined in the Investment Company Act of 1940 and the rules thereunder).

     As compensation for its services to the Fund, the Investment Adviser
receives monthly compensation at the rate of one twentieth of one percent of
month-end net asset value (0.6% annually), computed and paid each month.  The
ratio of the management fee to average net assets in 1995 was 0.6%; the ratio of
total expenses to average net assets was 0.99%.  Mairs and Power, Inc. has
agreed with the Fund that the expense ratio will not exceed the expense
limitation of any state in which the Fund's shares are sold.

     Advisory fees paid by the Fund to Mairs and Power, Inc. amounted to
$337,395 in 1995, $239,597 in 1994 and $217,158 in 1993.  Under the terms of the
Investment Advisory Agreement, the Investment Adviser agrees to render research,
statistical and advisory services to the Fund, pay for office rental, executive
salaries and executive expenses and pay all expenses related to the distribution
and sale of Fund shares.  All other expenses, such as brokerage commissions,
fees charged by the Securities and Exchange Commission, custodian and transfer
agent fees, legal and auditing fees, taxes, premiums on fidelity bonds,
supplies, and all other miscellaneous expenses are borne by the Fund.  No
compensation was paid to any other director or officer of the Fund.

TRANSFER AGENT AND CUSTODIAN

     Mairs and Power, Inc. acts as the Fund's Transfer Agent and Dividend
Disbursing Agent and is reimbursed for all expenditures incurred in the
discharge of these responsibilities.  Reimbursements amounted to $61,738 in
1995, $57,563 in 1994 and $38,991 in 1993.

     Custodial services for the Fund are performed by Norwest Bank Minnesota
N.A., Sixth and Marquette, Minneapolis MN 55479, pursuant to the terms of a
Custodial Agreement reviewed annually by the Board of Directors.  As Custodian,
Norwest Bank Minnesota N.A. controls all securities and cash for the Fund,
receives and pays for securities purchased, delivers against payment for
securities sold, receives and collects income from investments, makes all
payments for Fund expenses and performs other administrative services, as
directed in writing by authorized officers of the Fund.  For these services,
Norwest Bank Minnesota N.A. received $36,851 in 1995, $32,467 in 1994 and
$30,035 in 1993.

     Effective May 1, 1996 Firstar Trust Company of Milwaukee, WI will act as
Transfer Agent, Dividend Disbursing Agent and Custodian for the Fund, and will
assume all duties, responsibilities and control of these functions pursuant to
the same terms as set forth above.

PORTFOLIO TRANSACTIONS

     Subject to policies established by the Board of Directors of the Fund, the
Investment Adviser is responsible for the Fund's portfolio decisions and the
placing of orders to effect the Fund's portfolio transactions.  With respect to
such transactions, the Investment Adviser seeks to obtain the best net results
for the Fund taking into account such factors as price (including the applicable
brokerage commission or dealer spread), size of order, difficulty of execution
and operational facilities of the firm involved.  While the Investment Adviser
generally seeks reasonably competitive commission rates, the Fund will not
necessarily be paying the lowest commission or spread available.  The Fund has
no obligation to deal with any broker or dealer in the execution of its
portfolio transactions, and there is no affiliation between the Fund's officers
or directors, or its Investment Adviser, and any broker-dealer or affiliated
persons of any broker-dealer who executes transactions for the Fund.

     Investment decisions for the Fund are made independently from those of
Mairs and Power Income Fund, Inc., also managed by Mairs and Power, Inc.  When
these funds are simultaneously engaged in the purchase or sale of the same
securities the transactions are averaged as to price and allocated as to amount
in accordance with a formula deemed equitable to each fund.  In some cases this
system may adversely affect the price paid or received by the Fund, or the size
of the position obtainable for the Fund.

     Decisions with respect to allocations of portfolio brokerage will be made
by the Investment Adviser.  Portfolio transactions are normally placed with
broker-dealers which provide the Fund's Investment Adviser with research and
statistical assistance.  Recognizing the value of these factors, the Fund may
pay brokerage commissions in excess of those which another broker might charge
for effecting the same transaction, even though the research services furnished
by brokers through whom the Fund effects securities transactions may benefit
other clients of Mairs and Power, Inc.

     For the year 1995, the Fund paid $59,759 in brokerage fees on purchase and
sale of portfolio securities.  All of this amount was paid to brokers or dealers
who supplied research services to the Adviser.  Total brokerage fees for 1994
and 1993 amounted to $22,446 and $22,866, respectively.

Item 27.  INDEMNIFICATION

          The Fund's Amended and  Restated Articles of Incorporation state that
          a director of the corporation shall have no personal liability to the
          corporation or its shareholders for monetary damages for breach of
          fiduciary duty as a director to the full extent such immunity is
          permitted from time to time under the Minnesota Business Corporation
          Act, as now enacted or hereafter amended, except as prohibited by the
          Investment Company Act of 1940, as amended.

          Section 302A.521 of the Minnesota Business Corporation Act provides
          that a Minnesota corporation shall indemnify any director, officer, or
          employee of the corporation made or threatened to be made a party to a
          proceeding, by reason of the former or present official capacity of
          the person, against judgments, penalties, fines, settlements and
          reasonable expenses incurred by the person in connection with the
          proceeding, provided that certain statutory standards are met.
          "Proceeding" means a threatened, pending or completed civil, criminal,
          administrative, arbitration or investigative proceeding, including one
          by or in the right of the corporation.  Indemnification is required
          under Section 302A.521 only if the person (i) has not been indemnified
          by any other organization with respect to the same acts or omissions,
          (ii) acted in good faith, (iii) received no improper personal benefit,
          (iv) in the case of a criminal proceeding, had no reasonable cause to
          believe the conduct was unlawful, and (v) reasonably believed that the
          conduct was in the best interest of the corporation.

                               CUSTODIAN AGREEMENT


        THIS AGREEMENT made on April 15, 1996, between Mairs and Power Growth
Fund, Inc., a Minnesota corporation (hereinafter called the ("Fund"), and
FIRSTAR TRUST COMPANY, a corporation organized under the laws of the State of
Wisconsin (hereinafter called "Custodian"),

        WHEREAS, the Fund desires that its securities and cash shall be
hereafter held and administered by Custodian pursuant to the terms of this
Agreement;

        NOW, THEREFORE, in consideration of the mutual agreements herein made,
the Fund and Custodian agree as follows:

1. DEFINITIONS

        The word "securities" as used herein includes stocks, shares, bonds,
debentures, notes, mortgages or other obligations, and any certificates,
receipts, warrants or other instruments representing rights to receive, purchase
or subscribe for the same, or evidencing or representing any other rights or
interests therein, or in any property or assets.

        The words "officers' certificate" shall mean a request or direction or
certification in writing signed in the name of the Fund by any two of the
President, a Vice President, the Secretary and the Treasurer of the Fund, or any
other persons duly authorized to sign by the Board of Directors.

        The word "Board" shall mean Board of  Directors of  Mairs and Power
Growth Fund, Inc.

2. NAMES, TITLES, AND SIGNATURES OF THE FUND'S OFFICERS

        An officer of the Fund will certify to Custodian the names and
signatures of those persons authorized to sign the officers' certificates
described in Section 1 hereof, and the names of the members of the Board of
Directors, together with any changes which may occur from time to time.
        
3. RECEIPT AND DISBURSEMENT OF MONEY

        A.   Custodian shall open and maintain a separate account or accounts
in the name of the Fund, subject only to draft or order by Custodian acting
pursuant to the terms of this Agreement.  Custodian shall hold in such account
or accounts, subject to the provisions hereof, all cash received by it from or
for the account of the Fund.  Custodian shall make payments of cash to, or for
the account of, the Fund from such cash only:


                                      - 1 -
<PAGE>


        (a) for the purchase of securities for the portfolio of the Fund upon
            the delivery of such securities to Custodian, registered in the
            name of the Fund or of the nominee of Custodian referred to in
            Section 7 or in proper form for transfer;

        (b) for the purchase or redemption of shares of the common stock of the
            Fund upon delivery thereof to Custodian, or upon proper
            instructions from the Mairs and Power Growth Fund, Inc.;

        (c) for the payment of interest, dividends, taxes, investment adviser's
            fees or operating expenses (including, without limitation thereto,
            fees for legal, accounting, auditing and custodian services and
            expenses for printing and postage);

        (d) for payments in connection with the conversion, exchange or
            surrender of securities owned or subscribed to by the Fund held by
            or to be delivered to Custodian; or 

        (e) for other proper corporate purposes certified by resolution of the
            Board of Directors of the Fund.  

        Before making any such payment, Custodian shall receive (and may rely
upon) an officers' certificate requesting such payment and stating that it is
for a purpose permitted under the terms of items (a), (b), (c), or (d) of this
Subsection A, and also, in respect of item (e), upon receipt of an officers'
certificate specifying the amount of such payment, setting forth the purpose for
which such payment is to be made, declaring such purpose to be a proper
corporate purpose, and naming the person or persons to whom such payment is to
be made, provided, however, that an officers' certificate need not precede the
disbursement of cash for the purpose of purchasing a money market instrument, or
any other security with same or next-day settlement, if the President, a Vice
President, the Secretary or the Treasurer of the Fund issues appropriate oral or
facsimile instructions to Custodian and an appropriate officers' certificate is
received by Custodian within two business days thereafter.

        B.   Custodian is hereby authorized to endorse and collect all checks,
drafts or other orders for the payment of money received by Custodian for the
account of the Fund.

        C.   Custodian shall, upon receipt of proper instructions, make federal
funds available to the Fund as of specified times agreed upon from time to time
by the Fund and the custodian in the amount of checks received in payment for
shares of the Fund which are deposited into the Fund's account.


                                      - 2 -
<PAGE>


4.  SEGREGATED ACCOUNTS

Upon receipt of proper instructions, the Custodian shall establish and maintain
a segregated account(s) for and on behalf of the portfolio, into which
account(s) may be transferred cash and/or securities.

5.  TRANSFER, EXCHANGE, REDELIVERY, ETC. OF SECURITIES

        Custodian shall have sole power to release or deliver any securities of
the Fund held by it pursuant to this Agreement.  Custodian agrees to transfer,
exchange or deliver securities held by it hereunder only:

        (a) for sales of such securities for the account of the Fund upon
            receipt by Custodian of payment therefore; 

        (b) when such securities are called, redeemed or retired or otherwise
            become payable; 

        (c) for examination by any broker selling any such securities in
            accordance with "street delivery" custom; 

        (d) in exchange for, or upon conversion into, other securities alone or
            other securities and cash whether pursuant to any plan of merger,
            consolidation, reorganization, recapitalization or readjustment, or
            otherwise; 

        (e) upon conversion of such securities pursuant to their terms into
            other securities; 

        (f) upon exercise of subscription, purchase or other similar rights
            represented by such securities; 

        (g) for the purpose of exchanging interim receipts or temporary
            securities for definitive securities; 

        (h) for the purpose of redeeming in kind shares of common stock of the
            Fund upon delivery thereof to Custodian; or 

        (i) for other proper corporate purposes.  

        As to any deliveries made by Custodian pursuant to items (a), (b), (d),
(e), (f), and (g), securities or cash receivable in exchange therefore shall be
deliverable to Custodian.  

        Before making any such transfer, exchange or delivery, Custodian shall
receive (and may rely upon) an officers' certificate requesting such transfer,
exchange or delivery,


                                      - 3 -
<PAGE>


and stating that it is for a purpose permitted under the terms of items (a),
(b), (c), (d), (e), (f), (g), or (h) of this Section 5 and also, in respect of
item (i), upon receipt of an officers' certificate specifying the securities to
be delivered, setting forth the purpose for which such delivery is to be made,
declaring such purpose to be a proper corporate purpose, and naming the person
or persons to whom delivery of such securities shall be made, provided, however,
that an officers' certificate need not precede any such transfer, exchange or
delivery of a money market instrument, or any other security with same or
next-day settlement, if the President, a Vice President, the Secretary or the
Treasurer of the Fund issues appropriate oral or facsimile instructions to
Custodian and an appropriate officers' certificate is received by Custodian
within two business days thereafter.

6.  CUSTODIAN'S ACTS WITHOUT INSTRUCTIONS

        Unless and until Custodian receives an officers' certificate to the
contrary, Custodian shall:  (a) present for payment all coupons and other income
items held by it for the account of the Fund, which call for payment upon
presentation and hold the cash received by it upon such payment for the account
of the Fund; (b) collect interest and cash dividends received, with notice to
the Fund, for the account of the Fund; (c) hold for the account of the Fund
hereunder all stock dividends, rights and similar securities issued with respect
to any securities held by it hereunder; and (d) execute, as agent on behalf of
the Fund, all necessary ownership certificates required by the Internal Revenue
Code or the Income Tax Regulations of the United States Treasury Department or
under the laws of any state now or hereafter in effect, inserting the Fund's
name on such certificates as the owner of the securities covered thereby, to the
extent it may lawfully do so.

7.  REGISTRATION OF SECURITIES

        Except as otherwise directed by an officers' certificate, Custodian
shall register all securities, except such as are in bearer form, in the name of
a registered nominee of Custodian as defined in the Internal Revenue Code and
any Regulations of the Treasury Department issued hereunder or in any provision
of any subsequent federal tax law exempting such transaction from liability for
stock transfer taxes, and shall execute and deliver all such certificates in
connection therewith as may be required by such laws or regulations or under the
laws of any state.  Custodian shall use its best efforts to the end that the
specific securities held by it hereunder shall be at all times identifiable in
its records.

        The Fund shall from time to time furnish to Custodian appropriate
instruments to enable Custodian to hold or deliver in proper form for transfer,
or to register in the name of its registered nominee, any securities which it
may hold for the account of the Fund and which may from time to time be
registered in the name of the Fund.


                                      - 4 -
<PAGE>


8.  VOTING AND OTHER ACTION

        Neither Custodian nor any nominee of Custodian shall vote any of the
securities held hereunder by or for the account of the Fund, except in
accordance with the instructions contained in an officers' certificate. 
Custodian shall deliver, or cause to be executed and delivered, to the
Corporation all notices, proxies and proxy soliciting materials with relation to
such securities, such proxies to be executed by the registered holder of such
securities (if registered otherwise than in the name of the Fund), but without
indicating the manner in which such proxies are to be voted.

9.  TRANSFER TAX AND OTHER DISBURSEMENTS

        The Fund shall pay or reimburse Custodian from time to time for any
transfer taxes payable upon transfers of securities made hereunder, and for all
other necessary and proper disbursements and expenses made or incurred by
Custodian in the performance of this Agreement.

        Custodian shall execute and deliver such certificates in connection
with securities delivered to it or by it under this Agreement as may be required
under the provisions of the Internal Revenue Code and any Regulations of the
Treasury Department issued thereunder, or under the laws of any state, to exempt
from taxation any exemptable transfers and/or deliveries of any such securities.

10. CONCERNING CUSTODIAN

        Custodian shall be paid as compensation for its services pursuant to
this Agreement such compensation as may from time to time be agreed upon in
writing between the two parties.  Until modified in writing, such compensation
shall be as set forth in Exhibit A attached hereto.  If the Fund terminates this
Agreement prior to the first anniversary of this Agreement, the Fund agrees to
reimburse Custodian for the difference between the standard fee schedule and the
discounted fee schedule agreed to between the parties.

        Custodian shall exercise reasonable care in the performance of its
duties under this Agreement.  Custodian shall not be liable for any error of
judgment or mistake of law or for any loss suffered by the Fund in connection
with matters to which this Agreement relates, including losses resulting from
mechanical breakdowns or the failure of communication or power supplies beyond
Custodian's control, except a loss resulting from Custodian's refusal or failure
to comply with the terms of this Agreement or from bad faith, negligence, or
willful misconduct on its part in the performance of its duties under this
Agreement.  Notwithstanding any other provision of this Agreement, the Fund
shall indemnify and hold harmless Custodian from and against any and all claims,
demands, losses, expenses, and liabilities (whether with or without basis in
fact or law) of any and every nature (including reasonable attorneys' fees)
which Custodian may sustain or incur or which may be asserted against Custodian
by any person arising out of any action taken or omitted


                                      - 5 -
<PAGE>


to be taken by it in performing the services hereunder (i) in accordance with
the foregoing standards, or (ii) in reliance upon any written or oral
instruction provided to Custodian by any duly authorized officer of the Fund,
such duly authorized officer to be included in a list of authorized officers
furnished to Custodian and as amended from time to time in writing by resolution
of the Board of Directors of the Fund.

        In the event of a mechanical breakdown or failure of communication or
power supplies beyond its control, Custodian shall take all reasonable steps to
minimize service interruptions for any period that such interruption continues
beyond Custodian's control.  Custodian will make every reasonable effort to
restore any lost or damaged data and correct any errors resulting from such a
breakdown at the expense of Custodian.  Custodian agrees that it shall, at all
times, have reasonable contingency plans with appropriate parties, making
reasonable provision for emergency use of electrical data processing equipment
to the extent appropriate equipment is available.  Representatives of the Fund
shall be entitled to inspect Custodian's premises and operating capabilities at
any time during regular business hours of Custodian, upon reasonable notice to
Custodian.

        Regardless of the above, Custodian reserves the right to reprocess and
correct administrative errors at its own expense.

        In order that the indemnification provisions contained in this section
shall apply, it is understood that if in any case the Fund may be asked to
indemnify or hold Custodian harmless, the Fund shall be fully and promptly
advised of all pertinent facts concerning the situation in question, and it is
further understood that Custodian will use all reasonable care to notify the
Fund promptly concerning any situation which presents or appears likely to
present the probability of such a claim for indemnification against the Fund. 
The Fund shall have the option to defend Custodian against any claim which may
be the subject of this indemnification.  In the event that the Fund so elects,
it will so notify Custodian and thereupon the Fund shall take over complete
defense of the claim, and Custodian shall in such situation initiate no further
legal or other expenses for which it shall seek indemnification under this
section.  Custodian shall in no case confess any claim or make any compromise in
any case in which the Fund will be asked to indemnify Custodian except with the
Fund's prior written consent.

        Custodian shall indemnify and hold the Fund harmless from and against
any and all claims, demands, losses, expenses, and liabilities (whether with or
without basis in fact or law) of any and every nature (including reasonable
attorneys' fees) which may be asserted against the Fund by any person arising
out of any action taken or omitted to be taken by Custodian as a result of
Custodian's refusal or failure to comply with the terms of this Agreement, its
bad faith, negligence, or willful misconduct.


                                      - 6 -

12. SUBCUSTODIANS

        Custodian is hereby authorized to engage another bank (as defined in
Section 2.5 of the Investment Company Act of 1940) or trust company as a
Subcustodian for all or any part of the Fund's assets, so long as any such bank
or trust company is a bank or trust company organized under the laws of any
state of the United States, having an aggregate capital, surplus and undivided
profit, as shown by its last published report, of not less than Two Million
Dollars ($2,000,000) and provided further that, if the Custodian utilizes the
services of a Subcustodian, the Custodian shall remain fully liable and
responsible for any losses caused to the Fund by the Subcustodian as fully as if
the Custodian was directly responsible for any such losses under the terms of
the Custodian Agreement.

        Notwithstanding anything contained herein, if the Fund requires the
Custodian to engage specific Subcustodians for the safekeeping and/or clearing
of assets, the Fund agrees to indemnify and hold harmless Custodian from all
claims, expenses and liabilities incurred or assessed against it in connection
with the use of such Subcustodian in regard to the Fund's assets, except as may
arise from its own negligent action, negligent failure to act or willful
misconduct.

13. REPORTS BY CUSTODIAN

        Custodian shall furnish the Fund periodically as agreed upon with a
statement summarizing all transactions and entries for the account of Fund. 
Custodian shall furnish to the Fund, at the end of every month, a list of the
portfolio securities showing the aggregate cost of each issue.  The books and
records of Custodian pertaining to its actions under this Agreement shall be
open to inspection and audit at reasonable times by officers of, and of auditors
employed by, the Fund.

14. TERMINATION OR ASSIGNMENT

To The Shareholders
 
    1995 was a vintage year for shareholders of Mairs and Power Growth Fund. Net
asset value per share at year end was $56.64 resulting in a total return for the
year  of 49.3%. This compares  very favorably with returns  of 36.9% for the Dow
Jones Industrial Average and  37.5% for the Standard  & Poor's 500 Stock  Index.
According  to Lipper Analytical Services, the  average domestic stock fund had a
31.1% return for the year. A WALL STREET JOURNAL survey ranked the Fund 5th  out
of  558 Long  Term Growth Funds  for the year.  For the five  year period ending
December 31, the Fund had an average annual total return of 22.2% which compares
favorably with returns of 17.6% for the Dow Jones Industrial Average, 16.6%  for
the Standard & Poor's 500 Stock Index and 16.2% for the average long term growth
stock  fund. In  a study of  mutual funds' performance  by CDA/Wiesenberger, the
Fund ranked 24th out of 312 long term growth funds for the five year period  and
19th out of 186 similar funds for the ten year period. U.S. NEWS & WORLD REPORT,
in  an Annual  Guide to  Mutual Funds, surveyed  692 long-term  growth funds and
ranked the Fund 2nd, based on an overall performance index combining the past 1,
3, 5 and 10 year periods.
 
    The U.S. Economy grew at  a modest 2% annual rate  in 1995, down from 4%  in
1994.  The slower growth was the result  of a rather restrictive monetary policy
on the  part  of the  Federal  Reserve and  the  gradual liquidation  of  excess
inventories.  Inflation remained  subdued with  the Consumer  Price Index rising
just 2.5%. This represents the fourth consecutive year with inflation under  3%,
the  best such  performance in thirty  years. The current  economic expansion is
about to  enter its  sixth year  which makes  it now  the third  longest in  the
post-war  period. However, we  believe that this expansion  is well balanced and
therefore may very  well continue for  an extended period  of time. The  Federal
Reserve  has reduced interest  rates on three  separate occasions since mid-1995
and we believe further reductions may follow in the months ahead in an effort to
ensure stronger economic growth over the balance of the year.
 
    Stocks had a spectacular performance in 1995 and the Standard and Poor's 500
Stock Index registered its strongest  gain since 1958. Three positive  surprises
during  the year contributed to the performance. First, long term interest rates
were  expected  to  remain   steady  during  the   year  but  instead   declined
significantly  resulting in a  sharp rise in the  bond market. Second, corporate
earnings were stronger  than anticipated with  earnings for the  S&P 500  rising
about  16%. Finally, investors became more hopeful that fiscal policy was moving
in a  more conservative  direction which  would restrain  future inflation.  The
federal  deficit declined to  2.3% of G.D.P.  in fiscal 1995,  down from 4.9% in
1992. Furthermore, virtually all Washington policy-makers now recognize the need
to slow the rise in federal spending and further reduce the federal deficit.
 
    While  last  year's  very  strong  performance  should  temper  our   market
expectations,  we still remain constructive. The economic environment we foresee
for 1996 should provide a favorable background for equity investors. Stocks  are
currently  trading  at 16  times  projected 1996  earnings  which is  an average
valuation level for periods of low  inflation such as the present.  Furthermore,
we  continue  to  be  impressed  with  the  vitality  of  U.S.  corporations and
particularly their  renewed ability  to compete  effectively in  world  markets.
Therefore, we believe that corporate profits will continue to improve, albeit at
a  more moderate rate, and hence provide the basic underpinning for higher stock
prices in the months ahead.

                              GEORGE C. POWER, JR.
                                   1914-1995
 
    George Power  began his  investment career  in 1933  while he  was still  an
undergraduate at Carleton College. He held a summer job at Northwestern National
Bank  of Minneapolis where his  responsibilities included valuing collateral for
customers who had borrowed funds to purchase securities prior to the 1929 market
crash. At an early  age, he learned  the relationship of  risk and reward.  Upon
graduation  from college, he jointed the Investment Research Department of First
Bank Stock Corporation  where he made  many life-long friends,  several of  whom
played  leadership roles in the investment community of the Twin Cities. After a
stint in the U.S. Army during World War II where he rose to the rank of Captain,
he became a partner of George A. Mairs,  Jr. who founded the firm in 1931  which
subsequently   became  Mairs  and  Power,  Investment  Counsel.  George  Power's
remarkable investment career spanned 62 years  and continued until his death  on
July  18, 1995. While he received many accolades  along the way, he will best be
remembered for his uncommon  concern for all  of the people  he knew and  served
during  this long and fruitful career. George  served as an Officer and Director
of Mairs and Power Growth Fund from its inception in 1958 until the time of  his
death.  While he suffered physical impairment  in recent years, his intellectual
powers and great enthusiasm for life remained undiminished. His wise counsel and
high level of personal integrity served as  a constant inspiration to all of  us
who had the good fortune to share his association.

                         NOTES TO FINANCIAL STATEMENTS
                               DECEMBER 31, 1995
 
Note 1 -- The  fund is registered  under the Investment Company  Act of 1940 (as
          amended) as  a diversified,  no-load, open-end  management  investment
          company.   The  investment  objective  of   the  Fund  is  to  provide
          shareholders with a diversified holding of securities which appear  to
          offer  marked possibilities for long-term appreciation. Normally these
          will be common stocks.
 
Note 2 -- Significant accounting policies of the Fund are as follows:
 
            (a) Market value of investments is  based on the last reported  sale
                price  on December 31  for listed securities or  the mean of the
                bid and asked price for other securities. Security  transactions
                are recorded on the trade date, the date on which securities are
                purchased   or  sold.  Dividend  income  is  recognized  on  the
                ex-dividend date and interest income is recorded on the  accrual
                basis.  The cost of  securities sold is  determined based on the
                specific identification method.
 
            (b) No provision has been made for Federal income taxes as it is the
                intention of  the Fund  to  comply with  the provisions  of  the
                Internal  Revenue Code applicable to investment companies and to
                make distributions of  income and security  gains sufficient  to
                relieve it from all or substantially all income taxes.
 
            (c) The  Fund allows the accounting  practice known as equalization.
                When Fund shares are issued  or redeemed, the distributable  net
                investment   income  per   share  is  credited   or  charged  to
                undistributed net  investment income;  therefore,  undistributed
                net  investment income  per share  is not  affected by  sales or
                redemptions.
 
Note 3 -- Purchases and  sales of  investment securities,  excluding  short-term
          securities,  during  the  year  ended  December  31,  1995  aggregated
          $7,785,106 and $2,073,484, respectively.
 
Note 4 -- At December 31, 1995, the accumulated undistributed realized net  gain
          on  investments  sold  was  $51,804.  Net  unrealized  appreciation on
          investments for federal income tax purposes aggregated $46,065,977, of
          which $46,078,243  related to  appreciated investment  securities  and
          $12,266  related to depreciated  investment securities. Aggregate cost
          of investments for Federal income tax purposes was $21,664,834.
 
Note 5 -- The investment advisory fees were paid to Mairs and Power, Inc., which
          is owned by individuals  who are directors and  officers of the  Fund,
          for  its services as investment adviser. Investment advisory fees were
          paid to the adviser pursuant to an advisory agreement approved by  the
          directors  of the Fund. The advisory fee is computed each month and is
          1/20 of one percent  of the net  asset value of the  Fund on the  last
          valuation  day of the month. The transfer agent fees were also paid to
          Mairs and Power, Inc. who serves  as transfer agent. Directors of  the
          Fund  not affiliated with Mairs  and Power, Inc. received compensation
          for meetings attended  totaling $14,850 in  1995. No compensation  was
          paid to any other director or officer of the Fund.
 
Note 6 -- At  December 31, 1995, there were 10,000,000 shares of $0.01 par value
          capital stock  authorized and  additional paid-in  capital  aggregated
          $24,500,223.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and Shareholders
Mairs and Power Growth Fund, Inc.
 
We  have audited  the accompanying  statement of net  assets of  Mairs and Power
Growth Fund, Inc. (the Fund) as of December 31, 1995, and the related  statement
of  operations for the year then ended,  the statements of changes in net assets
for each of the two years in the period then ended, and the financial highlights
for each of the ten years in  the 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
December  31, 1995, by correspondence with the custodian. 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 Mairs
and Power Growth Fund, Inc. at December 31, 1995, the results of its  operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the ten years
in  the  period  then ended  in  conformity with  generally  accepted accounting
principles.
