Fourth Quarter Results

The Fund continued to participate in the stock market recovery that reflected a slowly improving economy during the final quarter of 2010. With a total investment return of 10.2%, the Fund out-paced a comparable return of 8.0% for the Dow Jones Industrial Average but was modestly below a return of 10.8% for the benchmark Standard & Poor's 500 Index. The Fund's performance also slightly lagged an average return of 10.9% for a peer group Lipper universe of multi-cap core funds shown in the Wall Street Journal.

For the full year in 2010, the Fund performed quite well, achieving a total return of 17.4% which was better than most of the popular stock market indices as well as comparable peer group measures. By comparison, the DJIA and S&P 500 stock indices posted returns of 14.1% and 15.1%, respectively, while the Lipper universe of multi-cap core funds had an average return of 15.9% for the year.

The economy ended the year on a positive note, showing a fourth quarter real Gross Domestic Product gain of 3.2% (preliminary basis) on the strength of a long-awaited pick-up in consumer spending which occurred during the all-important Christmas season. The increase was powered by a 21.6% gain in durable goods sales due in large part to a significant rise in automobile sales. Business spending on equipment and software continued to increase, although at a slower 5.8% rate compared to a much higher 15.4% in the previous quarter. However, spending on structures rose a slight 0.8%, the first such quarterly increase in nearly three years. Government spending slipped 0.6% in the face of growing concerns over deficit spending at both the federal and state levels. Finally, corporate profit growth based on the S&P 500 Index is estimated to have increased by more than 30% during the period.

With the economy beginning to show some signs of gaining traction, interest rates have started to increase at the longer end of the curve, reflecting a higher anticipated rate of inflation. In this regard, the ten year U.S. Treasury yield increased by more than ³/₄ of a percentage point during the quarter. Shorter term rates were essentially unchanged during the same period as Federal Reserve policy remained very stimulative.

The stock market rally continued during the quarter in response to a number of factors including sharply higher corporate profits, historically low interest rates and reasonable

valuation levels. As might be expected, the best performing issues seemed to be those with cyclical leverage while the weaker issues were those characterized by being more defensive in nature. Among individual holdings in the Fund, the best performers included Daktronics (+62.1%), G&K Services (+35.2%), Principal Financial Group (+25.6%), U.S. Bancorp (+24.7%) and Graco (+24.3%). The worst performing issues included SUPERVALU (-16.5%), TCF Financial (-8.5%), General Mills (-2.6%), Ecolab (-0.6%) and 3M (-0.5%).

Future Outlook

Absent unforeseen events on the world stage, the outlook for the U.S. economy suggests continuing gradual improvement in the area of 3%. Even though unemployment is expected to remain high for some time to come, a rising level of confidence is expected to continue to help bolster consumer spending, at least over the near term. While business spending may not be as vibrant as in recent quarters, growth is nevertheless expected to continue in response to the ever increasing need for productivity improvement in order to remain competitive in the global marketplace. In this regard, corporations are well positioned to fund a rising level of investment spending as a result of increasing cash flow and strong balance sheets. Corporate profits seem likely to continue showing well above-average growth, at least through the first half of 2011. This will be driven by continuing improvement in the domestic economy, further pro ductivity gains and faster foreign growth, especially in the Far East.

While some forecasters are looking for a further acceleration in the rate of economic growth, our optimism is tempered by a number of factors including a continuing high level of unemployment, depressed home prices, rising taxes due to federal and state budgetary problems and the likelihood of an increasing rate of inflation resulting from higher food and energy prices.

If in fact a higher inflation rate materializes, the Federal Reserve may be forced to tighten monetary policy even without any meaningful improvement in the unemployment picture. This could result in some flattening of the current historically steep U.S. Treasury yield curve which reflects the recent increase in longer term interest rates.

TO OUR SHAREHOLDERS (continued)

The outlook for stock prices remains favorable, at least for the time being, considering the prospects for further above-average earnings growth, reasonable valuation levels and relatively low interest rates. Moreover, we also believe investors have considerable liquidity with which to fund further stock purchases.

NOTES TO FINANCIAL STATEMENTS  December 31, 2010

Note 1 – Organization and Significant Accounting Policies

The Mairs and Power Growth Fund, Inc. (the Fund) is registered under the Investment Company Act of 1940 (as amended) as a diversified, no-load, open-end management investment company. The objective of the Fund is to provide shareholders with a diversified portfolio of common stocks, which have the potential for above-average, long-term appreciation.

Significant accounting policies of the Fund are as follows:

Security Valuations

Security valuations for Fund investments are furnished by independent pricing services that have been approved by the Fund's Board of Directors (the Board). Investments in equity securities are valued at the NASDAQ Official Closing Price if readily available for such securities on each business day. Other equity securities traded in the over-the-counter market and listed equity securities for which no sale was reported on that date are stated at the last quoted bid price. Debt obligations with 60 days or less remaining until maturity may be valued at their amortized cost, which approximates fair value.

Securities for which prices are not available from an independent pricing service, but where an active market exists, are valued using market quotations obtained from one or more dealers that make markets in the securities or from a widely used quotation system. When market quotations are not readily available, or where the last quoted sale price is not considered representative of the value of the 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 Fair Valuation Committee appointed by the Board, pursuant to procedures approved by the Board. Factors that may be considered in determining the fair value of a security are fundamental analytical data relating to the security, the nature and duration of any restrictions on the disposition of the security, and the forces influencing the market in which the security is purchased or sold. As of December 31, 2010, no securities in the Fund were valued using this method.

Fair Valuation Measurements

The Fund has adopted authoritative fair valuation accounting standards which establish a definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs and valuation techniques used to develop the measurements of fair value and changes in valuation techniques and related inputs during the period. These inputs are summarized in the three broad levels listed below:

•  Level 1 – Quoted prices in active markets for identical securities.

•  Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

12

NOTES TO FINANCIAL STATEMENTS (continued)  December 31, 2010

Note 1 – Organization and Significant Accounting Policies (continued)

•  Level 3 – Significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. All of the inputs used to value the Fund's investments as of December 31, 2010 were classified as Level 1. For detail of investments by major industry classification, please refer to the Schedule of Investments. There were no transfers between levels during the year. The Fund did not hold any level 3 investments at either December 31, 2010 or December 31, 2009.

In January 2010, new accounting guidance was issued that requires enhanced disclosures about fair value measurements in the financial statements. Certain requirements related to Level 3 fair value measurements are effective for fiscal years and interim periods beginning after December 15, 2010. Management does not expect that the disclosures will have a significant impact on the Fund's financial statements.

Security Transactions and Investment Income

Security transactions are recorded on the date on which securities are purchased or sold. Dividend income and corporate action transactions are recorded on the ex-dividend date and interest income is recorded on an accrual basis. Realized gains and losses are reported on an identified cost basis.

Income Taxes

The Fund is a "regulated investment company" as defined in Subtitle A, Chapter 1, Subchapter M of the Internal Revenue Code (the Code), as amended. No provision has been made for federal income taxes as it is the intention of the Fund to comply with the provisions of the Code applicable to regulated investment companies and to make distributions of income and realized gains sufficient to relieve it from all or substantially all excise and income taxes.

As of December 31, 2010, the Fund did not have any tax positions that did not meet the "more-likely-than-not" threshold of being sustained by the applicable tax authority. Generally, tax authorities can examine all the tax returns filed for the last three years.

Basis of Presentation

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amount of net assets and liabilities and disclosure of contingent assets and liabilities at the date

13

NOTES TO FINANCIAL STATEMENTS (continued)  December 31, 2010

Note 1 – Organization and Significant Accounting Policies (continued)

of the financial statements and the reported results of operations during the reporting period. Actual results could differ from those estimates.

In preparing these financial statements, the Fund has evaluated events and transactions for potential recognition or disclosure through the date the financial statements were issued. This evaluation did not result in any subsequent events that necessitated recognition or disclosures.

Note 2 – Related-Party Transactions

Investment Management and Fund Administration Fees

Mairs and Power, Inc. (the Adviser) provides investment management and fund administration services to the Fund under written agreements approved by the Board. The Fund is charged an investment management fee paid to the Adviser computed at an annual rate of 0.60% of daily net assets up to $2.5 billion, and 0.50% of daily net assets in excess of $2.5 billion. The fund administration fee paid to the Adviser is computed at an annual rate of 0.00375% of daily net assets. For the year ended December 31, 2010, the Fund incurred $71,772 in administration fees from the Adviser, and as of December 31, 2010, had an accrued liability of $6,439 for administration fees payable to the Adviser.

Pursuant to a sub-administration agreement between the Fund and U.S. Bancorp Fund Services, LLC ("USBFS"), the Fund is charged a sub-administration fee paid to USBFS. For the year ended December 31, 2010, the Fund incurred $160,170 in sub-administration fees from USBFS, and as of December 31, 2010, had an accrued liability of $38,806 for sub-administration fees payable to USBFS.

Directors' Compensation

Directors' compensation is paid to individuals who are disinterested directors of the Fund. No compensation is paid to the owners of the Adviser, including principal officers who are not directors of the Fund and William B. Frels, who is an interested director and officer of the Fund.

Contributions from Adviser

During the year, the Fund received two contributions from the Adviser related to prospect services and other expenses paid by the Fund from 1980-2009, which were in violation of the Investment Company Act of 1940. The contribution amounts, which included imputed interest, as disclosed in the Statement of Changes in Net Assets, were $1,192,736 or $0.04 per share based upon shares outstanding as of May 21, 2010, and $8,271 or $0.0003 per share based upon shares outstanding as of September 24, 2010.

NOTES TO FINANCIAL STATEMENTS (continued)  December 31, 2010

Note 3 – Indemnifications

In the normal course of business, the Fund enters into contracts that contain general indemnifications to other parties. The Fund's maximum exposure under these contracts is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote.

Note 4 – Distributions Paid, Distributable Earnings and Investment Transactions

Net investment income and net realized gains (losses) may differ for financial reporting and tax purposes because of temporary or permanent book/tax differences. To the extent these differences are permanent, reclassifications are made to the appropriate equity accounts in the period that the difference arises.

Additionally, U.S. generally accepted accounting principles require that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. For the year ended December 31, 2010, there were no reclassifications.

Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles. In addition, due to the timing of dividend distributions, the fiscal year in which the amounts are distributed may differ from the year that the income or realized gains (losses) were recorded by the Fund.

The tax character of distributions paid during the years ended December 31, 2010 and 2009, was as follows:

	2010		2009
Distributions paid from:
Ordinary income	$	25,157,413	$	27,356,845
Long-term capital gains		26,917,941		7,446,009
	$	52,075,354	$	34,802,854

The Fund designated as long-term capital gain dividend, pursuant to Internal Revenue Code Section 852(b)(3), the amount necessary to reduce the earnings and profits of the Fund related to net capital gain to zero for the tax year ended December 31, 2010.

NOTES TO FINANCIAL STATEMENTS (continued)  December 31, 2010

Note 4 – Distributions Paid, Distributable Earnings and Investment Transactions (continued)

At December 31, 2010, the components of accumulated earnings (losses) on a tax basis were as follows:

Cost of investments	$	1,373,689,523
Gross unrealized appreciation	$	790,391,297
Gross unrealized depreciation		(131,296,272	)
Net unrealized appreciation	$	659,095,025
Undistributed ordinary income	$	97,147
Undistributed long-term capital gains		98,329
Total distributable earnings	$	195,476
Total accumulated earnings	$	659,290,501

The difference between book basis and tax basis unrealized appreciation is attributable primarily to the tax deferral of losses on wash sales.

Purchases and sales of investment securities, excluding government securities, short-term securities and temporary cash investments, during the year ended December 31, 2010, aggregated $33,727,642 and $237,355,449, respectively. No purchases and sales of government securities occurred during the year.

The Fund owned 5% or more of the voting securities of the following companies during the year ended December 31, 2010. As a result, these companies are deemed to be affiliates of the Fund as defined by the Investment Company Act of 1940. Transactions during the period in these securities of affiliated companies were as follows:

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors
Mairs and Power Growth Fund, Inc.

We have audited the accompanying statement of assets and liabilities of the Mairs and Power Growth Fund, Inc. (the Fund), including the schedule of investments, as of December 31, 2010, 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 five 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 the standards of the Public Company Accounting Oversight Board (United States). 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. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principl es used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2010, by correspondence with the custodian and brokers, or by other appropriate auditing procedures where replies from brokers were not received. 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 the Mairs and Power Growth Fund, Inc. at December 31, 2010, 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 five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

FUND EXPENSES (unaudited)

As a shareholder of the Fund, you incur ongoing expenses for the operation of the Fund (e.g., asset-based charges, such as investment management fees). The Fund is a "no-load" mutual fund. As a result, shareholders pay no commissions, fees, or expenses associated with sales representatives or sales charges.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The table below reports the Fund's expenses during the period from July 1, 2010 through December 31, 2010 and includes the costs associated with a $1,000 investment.

Actual Expenses

The first line in the table below may be used to estimate the actual expenses you paid over the reporting period. You can do this by dividing your account value by $1,000 and multiplying the result by the expense shown in the table below. For example, if your account value is $8,600, divided by $1,000 = $8.60. Multiply the result by the number in the first line under the heading titled "Expenses Paid During Period." By doing this you can estimate the expenses you paid on your account during this period.

Hypothetical Example

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expenses and an assumed return of 5% per year before expenses, which is not the Fund's actual return. The results may be used to provide you with a basis for comparing the ongoing costs of investing in the Fund with the costs of investing in other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. Please note that this hypothetical example may not be used to estimate the actual ending account balance or expenses you paid during the period.

	Beginning Account Value 07/01/2010		Ending Account Value 12/31/2010		Expenses Paid During Period *
Actual return	$	1,000.00	$	1,195.80	$	3.93
Hypothetical assumed 5% return	$	1,000.00	$	1,021.63	$	3.62

*  The Fund's expenses are equal to the Fund's annualized expense ratio for the most recent six-month period of 0.71%, multiplied by the average account value over the Fund's second fiscal half-year, multiplied by the number of days in the Fund's second fiscal half-year (184 days), divided by 365 days.

EX-99.CODEETH

EX.99.CODE ETH

CODE OF ETHICS - MAIRS AND POWER GROWTH FUND, INC.

In accordance with Rule 17j-1 and Rule 204A-1 under the Investment Company Act of 1940 (the “Act”), Mairs and Power, Inc. has adopted the following code of ethics.

1.All access persons, namely the Fund’s directors, officers and advisory persons, shall be familiar with Rule 17j-1 and Rule 204A-1 under the Act and be governed by the spirit they represent.  Access persons shall act at all times with openness, honesty and integrity, avoiding actual or apparent conflicts of interest in personal and professional relationships.  Any material relationship or transaction that reasonably could be expected to give rise to such a conflict of interest shall be reported to the Chief Compliance Officer.

2.No access person, in connection with the purchase or sale, directly or indirectly, by such person of a security held or to be acquired by the Fund shall

a.employ any device, scheme or artifice to defraud the Fund;

b.make to the Fund any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements made, in light of the circumstances under which they are made, not misleading;

c.engage in any act, practice, or course of business which operates or would operate as a fraud or deceit upon the Fund; or

d.engage in any manipulative practice with respect to the Fund.

3.Access persons (other than directors who are not “interested persons” within the meaning of section 2(a)(19) of the Act (“Disinterested Directors”)) shall be required to submit an initial list of covered security holdings and the related accounts holding these securities within 10 days of becoming an access person.   The list shall include all covered securities where the access person had any direct or indirect beneficial ownership interest and the date the list was submitted.  The list of holdings must be current as of a date not more than 45 days prior to the individual becoming an access person.  Subsequent covered security lists shall be submitted no less frequentl y than annually thereafter, except by Disinterested Directors.  Holdings in the Fund must be included in both the initial list and in subsequent annual lists.

4.No access person, or a person acting on his or her behalf, shall act in such a way as to benefit materially from the knowledge that the Fund has taken or is considering taking an investment position in a security, where such an action by the Fund is likely to influence the market price of that security.  In such cases, all access persons are prohibited from executing personal transactions on a day during which the Fund has a pending “buy” or “sell” order in that same security until that order is executed or withdrawn and for three calendar days after the day on which the Fund “buy” or “sell” order is executed.

Notwithstanding the above, all access persons are further prohibited from executing personal purchase transactions on any day in any stock while such stock is on the Mairs and Power “Recommended List” of its top fifteen recommended “buys” as developed and promulgated internally twice each month.  The Mairs and Power ““Recommended List” typically will form the basis for all stock purchases made by the Mairs and Power Funds.

In addition, each Fund portfolio manager is prohibited from buying or selling a security within at least seven calendar days before and after the Fund that he or she manages trades in that security.  All trades by access persons in securities either held by the Fund or being considered for purchase by the Fund require preclearance authorization before execution.  Such trades shall be executed only during the last half hour of trading so as not to inhibit Fund transactions.

Preclearance forms shall be prepared for all trades unless specifically excluded by this policy, note the time that the trade was executed and be signed by the Funds’ Manager or Co-Manager.  Preclearance is also specifically required for the purchase of any IPO’s and/or private placements.

The “blackout” periods described above with respect to the Funds do not apply to the Disinterested Directors unless they have actual knowledge of a pending Fund trade.  The “blackout” periods may be waived and the transaction requested by the access person may be pre-cleared if, in the judgment of the Fund portfolio manager, the proposed transaction is so small relative to the volume of daily trading activity of the security in question that its influence on the market price of that security would be infinitesimal.  As a general rule, it would be expected that such a “de minimus” waiver by the Fund portfolio manager would only be granted with respect to large cap stocks where the access person’s trade would be for less than $25,000.  Further, this “de minimus” waiver is not available with respect to the “Recommended List” purchase prohib ition discussed hereinabove.

5.Access persons (other than Disinterested Directors) are required to arrange with their brokerage firm(s) to have duplicate trade confirmations sent to the Mairs and Power Chief Compliance Officer for all of their trading transactions.  The Chief Compliance Officer must have duplicate trade confirmations for all of his trades sent to the Maris and Power Officer designated by the Mairs and Power Funds’ Board as the person responsible for reviewing the Chief Compliance Officers’ trades.  Access persons (other than Disinterested Directors) are also required to report all transactions within 30 days of the end of each calendar quarter.  A Disinterested Director will not be required to report transactions, except where such director knew or, in the ordinary course of fulfilling his or her official duties as a director of the Fund, should have known that during the 15-day period immediately preceding or after the date of the transaction in a security by the director such security is or was purchased or sold by the Fund or such purchase or sale by the Fund is or was considered by the Fund or its investment adviser.  The quarterly report shall include the date, description or security, amount, number of shares, type of transaction (buy or sell), price and broker used.  A signed statement by each access person will be required on a quarterly basis even if no personal trades were executed during the previous three-month period.  A copy of each report shall be kept for a period of at

least five years following the end of the fiscal year in which it is made, the first two years in an easily accessible place.

6.Preclearance of purchases or redemptions of shares of the Fund is not required, nor do such transactions need to be included in the quarterly report of security transactions described in #5 above.  However, access persons other than Disinterested Directors are required to submit to the Chief Compliance Officer of the Fund a copy of all Fund confirmations for trades made by said access person within ten days of the date of the confirmation.

7.The gift and entertainment policy of Mairs and Power Growth Fund, Inc. is based on the premise that gifts and entertainment may only be given/provided (or received) if the gift or entertainment is in accordance with normal and reasonable business practices and does not raise any question of impropriety.  The guidelines which follow have been established by Mairs and Power Growth Fund, Inc. in order to insure that the standards imposed by its gift and entertainment policy are maintained.

Selected access person shall not accept gifts from (or give gifts to) any client, broker, dealer, financial institution or any other entity which provides goods or services to Mairs and Power Growth Fund, Inc.  This prohibition shall not apply to small gifts which do not exceed $100 in value in any one calendar year.  Similarly, this prohibition shall not apply to a reasonable level of participation in business lunches, dinners, receptions, sporting events, golf outings, concerts or other social gatherings conducted by Mairs and Power Growth Fund, Inc. or its access persons for business purposes, or by an entity which is entertaining a Mairs and Power access person for business purposes.  With respect to such examples of business entertainment, the maximum value for each such activity or event shall be $250.  The maximum aggregate value per year of such entertainment for the b enefit of Mairs and Power access persons from a single outside entity (or to a single outside entity from Mairs and Power) shall not exceed $1000.

Access persons are required to report quarterly to the Chief Compliance Officer any gifts and/or entertainment that he or she has received from any person or entity, or that he or she has given or provided to any person or entity.  Modest entertainment received by an access person of Mairs and Power, such as analyst’s breakfast or luncheon meetings, or any similar events having a total value of less than $100 are not required to be reported.  Similarly, occasional gifts of small value from an outside entity  that are intended for the use and benefit of the entire staff of Mairs and Power Growth Fund, Inc., e.g., a fruit basket,  coffee cake, or a dessert item, are also not required to be reported.  In the event circumstances arise which may suggest that it might be reasonable to vary somewhat from the requirements of this policy, only the Chief Compliance Officer is autho rized to grant such a waiver.  Further, such a waiver by the Chief Compliance Officer can only be granted in advance of the gift or entertainment activity under consideration.

8.It shall be the responsibility of the Chief Compliance Officer designated by the Board to report quarterly to the Board of Directors any violations of this code.    Access persons who observe any violations of the Code must promptly report them to the Chief Compliance Officer.  The Chief Compliance Officer shall provide the Board at least annually with a written report attesting to a full review of compliance activities and detailing any violations that have taken

place since the last report. Violations shall be recorded, with an appropriate course of action, and kept for at least five years following the end of the fiscal year in which the violations occurs.

9.The Chief Compliance Officer shall identify each access person, supply each access person with a copy of this code, and any amendments thereto, and shall inform such persons of their duty to report covered security holdings and transactions.  Each access person shall acknowledge receipt in writing.

10.A copy of this code of ethics shall be kept in an easily accessible place.

11.Concerning the trading activities of the spouse of an access person, such trading is not subject to the provisions of Item 4 other than the requirement to obtain preclearance of investments in IPOs and private placements.  This exception is only available if the access person is not in any way involved in the trading decision and the spouse has no actual knowledge of pending client “buy” or “sell” orders, no actual knowledge of securities being considered for purchase or sale by a client and no actual knowledge of securities on the “Recommended List”.  Spousal trading activities, however, remain subject to the requirements that duplicate trade confirmations be sent to the Mairs and Power Chief Compliance Officer and that the access person include all such spousal accounts on the initial and annual holdings reports referenced in Item 3.  In connection with Chief Compliance Officer’s review of this information, the exception from the provisions of Item 4 set forth above may be revoked at any time with respect to a particular access person’s spouse.
