Exhibit 10.16

                            PATTERSON DENTAL COMPANY
                 2001 NON-EMPLOYEE DIRECTORS' STOCK OPTION PLAN

1. Purpose

The purpose of the Patterson Dental Company 2001 Non-Employee Directors' Stock
Option Plan ("the Plan") is to secure for Patterson Dental Company ("the
Company") and its shareholders the benefits of the incentive inherent in
increased Common Stock ownership by the members of the Board of Directors ("the
Board") of the Company who are Eligible Directors as defined in the Plan.

2. Administration

The Plan shall be administered by the Board. The Board shall have all the powers
vested in it by the terms of the Plan, such powers to include authority (within
the limitations described herein) to prescribe the form of the agreement
embodying awards of stock options made under the Plan ("Options"). The Board
shall, subject to the provisions of the Plan, grant Options under the Plan and
shall have the power to construe the Plan, to determine all questions arising
thereunder and to adopt and amend such rules and regulations for the
administration of the Plan as it may deem desirable. Any decision of the Board
in the administration of the Plan, as described herein, shall be final and
conclusive. The Board may act only by a majority of its members in office,
except that the members thereof may authorize any one or more of their number or
the Secretary or any other officer of the Company to execute and deliver
documents on behalf of the Board. No member of the Board shall be liable for
anything done or omitted to be done by such member or by any other member of the
Board in connection with the Plan, except for such member's own willful
misconduct or as expressly provided by statute.

3. Amount of Stock

The stock which may be issued and sold under the Plan will be the Common Stock
(par value $.01 per share) of the Company, of a total number not exceeding
400,000 shares, subject to adjustment as provided in Paragraph 6 below. In the
event that Options granted under the Plan shall terminate or expire without
being exercised in whole or in part, new Options may be granted covering the
shares not purchased under such lapsed Options.

4. Eligible Directors

The members of the Board who are eligible to participate in the Plan are persons
who serve as directors of the Company on or after the effective date of the Plan
and who are not current employees of the Company or any affiliate or subsidiary
of the Company.

5. Terms and Conditions of Options

Each Option granted under the Plan shall be evidenced by an agreement in such
form as the Board shall prescribe from time to time in accordance with the Plan
and shall comply with the following terms and conditions:

     (a)  The Option exercise price shall be the fair market value of the Common
          Stock shares subject to such Option on the date the Option is granted.
          The fair market value of the Common Stock shall be determined as
          follows:

          (i)  if the Common Stock is listed on a national securities exchange
               or admitted to unlisted trading privileges on such exchange, the
               fair market value on any



                given day shall be the average of the high and the low sales
                price of a Common Stock share on such day or, if such exchange
                is closed on that date, on the last preceding date on which such
                exchange was open for trading;

          (ii)  if the Common Stock is not listed on a national securities
                exchange, the fair market value on any given day shall be the
                average of the high and the low sales prices of a Common Stock
                share on the Nasdaq National Market on such day or, if the
                Nasdaq National Market is closed on that date, on the last
                preceding date on which the Nasdaq National Market was open for
                trading;

          (iii) if the Common Stock is not listed on a national securities
                exchange, is not admitted to unlisted trading privileges on any
                such exchange, and is not eligible for inclusion on the Nasdaq
                National Market, the fair market value on any given day shall be
                the average of the closing representative bid and asked prices
                on such day, as reported on the Nasdaq National Market, and if
                not reported on such Market, then as reported by the National
                Quotation Bureau, Inc. or such other publicly available
                compilation of the bid and asked prices of the Common Stock in
                any over-the-counter market on which the Common Stock is traded;
                or

          (iv)  if there exists no public trading market for the Common Stock,
                the fair market value on any given day shall be an amount
                determined by the Board in such manner as it may reasonably
                determine in its discretion, provided that such amount shall not
                be less than the book value per share as reasonably determined
                by the Board as of the date of determination nor less than the
                par value of the Stock.

     (b)  Each year, as of the date of the annual meeting of shareholders of the
          Company, commencing with the 2002 annual meeting of the shareholders
          of the Company, each Eligible Director who has been elected or
          reelected or who is continuing as a member of the Board as of the
          adjournment of the annual meeting, shall automatically receive an
          Option award. The number of shares to be covered by an Option award to
          an Eligible Director who is elected to the Board for the first time,
          either by the shareholders of the Company or by the Board to fill a
          vacancy thereon, shall be 12,000 shares (an "Initial Grant"). The date
          of an Option award to a person first elected to the Board to fill a
          vacancy thereon shall be the date of such election. The number of
          shares to be covered by an Option award to an Eligible Director who is
          reelected to the Board or whose Board Membership is continuing
          following such annual meeting shall be 6,000 shares (an "Annual
          Grant"). The number of shares of any Option award shall be subject to
          adjustment as provided in Section 6. An Initial Grant shall also be
          awarded to an Eligible Director who is first elected to the Board
          prior to the Company's 2002 annual meeting, and who has not received
          the grant of a stock option under any other plan of the Company;
          provided, however, that if an Initial Grant is made within six months
          of an Annual Grant to which an Eligible Director would be entitled to
          receive, such Initial Grant shall be in lieu of the next succeeding
          Annual Grant.

     (c)  In addition to any Options received pursuant to Section 5(b), each
          Eligible Director shall automatically be granted the right to elect to
          receive additional Options in lieu of the amount of the director's
          annual fee such Eligible Director is entitled to receive ("Annual
          Retainer"), or a portion thereof, for the year following election or
          reelection to, or continuation on, the Board. Such election to receive
          additional Options shall be irrevocable and must be made in writing
          prior to the commencement of the period

                                       2



          prior to which the Annual Retainer is to be earned. Options granted
          subject to such election shall be granted on the first day of the
          Company's fiscal year in which such Annual Retainer is earned. The
          number of additional Options such Eligible Director can obtain
          pursuant to this Section shall be determined pursuant to the following
          formula:

          Amount of Annual
          Retainer to be Converted          =   Options Granted in Lieu of
          Stock Price per share on Date of      Cash
          Grant x Valuation Discount

          The Valuation Discount shall be based upon the Black-Scholes formula
          or upon such other discount as the Board determines to be appropriate.

     (d)  No Option granted under the Plan shall be transferable by the optionee
          other than by will or by the laws of descent and distribution, and
          such Option shall be exercisable, during the optionee's lifetime, only
          by the optionee. Notwithstanding the foregoing, the Board may set
          forth in a stock option agreement, at the time of grant or thereafter,
          that Options may be transferred to trusts solely for the benefit of
          such immediate family members and to partnerships in which such family
          members and/or trusts are the only partners. For this purpose,
          immediate family means the optionee's spouse, parents, children,
          stepchildren, grandchildren and legal dependants. Any transfer of
          Options made under this provision will not be effective until notice
          of such transfer is delivered to the Company.

     (e)  No Option or any part of an Option shall be exercisable:

          (i)   except as provided in Section 5(h) and Section 6(b), before the
                Eligible Director has served one term-year as a member of the
                Board since the date the Option was granted (as used herein, the
                term "term-year" means that period from one Annual Meeting to
                the subsequent Annual Meeting),

          (ii)  after the expiration of ten years from the date the Option was
                granted, or after the expiration of one year following the date
                on which the Eligible Director to whom the Option was granted
                ceased to be an Eligible Director for any reason.

          (iii) unless written notice of the exercise is delivered to the
                Company specifying the number of shares to be purchased and
                payment in full is made for the shares of Common Stock being
                acquired thereunder at the time of exercise, such payment shall
                be made:

                (A) in United States dollars by certified check, or bank draft,
                    or

                (B) by tendering to the Company Common Stock shares owned by the
                    person exercising the Option and having a fair market value
                    equal to the cash exercise price applicable to such Option,
                    such fair market value to be the average of the high and low
                    sales prices of a Common Stock share on the date of exercise
                    as reported on the Nasdaq National Market or, if the Nasdaq
                    National Market is closed on that date, on the last
                    preceding date on which the Nasdaq National Market was open
                    for trading, or

                                       3



               (C)  by a combination of United States dollars and Common Stock
                    shares as aforesaid, and

          (iv) unless the person exercising the Option has been, at all times
               during the period beginning with the date of grant of the Option
               and ending on the date of such exercise, an Eligible Director of
               the Company, except that if such person shall cease to be such an
               Eligible Director, for any reason, while holding an Option that
               has not expired and has not been fully exercised, such person, or
               in the case of death, the executors, administrators, legatees or
               distributes, as the case may be, at any time within one year
               after the date such person ceases to be such an Eligible Director
               (but in no event after the Option has expired under the
               provisions of subparagraph 5(e)(ii) above), may exercise the
               Option with respect to any Common Stock shares as to which such
               person has not exercised the Option on the date the person ceased
               to be such an Eligible Director.

               In the event any Option is exercised by the executors,
               administrators, legatees or distributees of the estate of a
               deceased optionee, the Company shall be under no obligation to
               issue stock thereunder unless and until the Company is satisfied
               that the person or persons exercising the Option are the duly
               appointed legal representatives of the deceased optionee's estate
               or the proper legatees or distributees thereof.

     (f)  Subject to subparagraph 5(e) above, an Option shall become exercisable
          in full beginning on the earlier of (a) the first anniversary date of
          the grant of the Option or (b) the completion of one term-year
          following the grant of the Option.

     (g)  Notwithstanding anything to the contrary herein, if an Option has been
          transferred in accordance with Section 5(d), the Option shall be
          exercisable solely by the transferee. The Option shall remain subject
          to the provisions of the Plan, including that it will be exercisable
          only to the extent that the optionee or optionee's estate would have
          been entitled to exercise it if the optionee had not transferred the
          Option. In the event of the death of the transferee prior to the
          expiration of the right to exercise the Option, the Option shall be
          exercisable by the executors, administrators, legatees and
          distributees of the transferee's estate, as the case may be, for a
          period of one year following the date of the transferee's death but in
          no event be exercisable after the expiration of the Option period set
          forth in the Stock Option Agreement. The Option shall be subject to
          such other rules or terms as the Board shall determine.

     (h)  In the case of an Initial Grant, one-third of such Option shall become
          exercisable on the first, second and third anniversaries of the date
          of grant, respectively.

6. Adjustment Upon Certain Events

     (a)  In the event of changes in the outstanding Common Stock of the Company
          by reason of any stock dividend, recapitalization, merger,
          consolidation, split-up, combination, exchange of shares, rights
          offering to purchase stock at a price substantially below market
          value, or the like, the aggregate number and kind of shares available
          under the Plan, and the number, kind and price of shares subject to
          outstanding Options, shall be appropriately adjusted by the Board,
          whose determination shall be conclusive.

                                       4



     (b)  Upon the occurrence of a Change of Control, (i) all outstanding
          Options granted pursuant to the Plan, to the extent not theretofore
          exercised or canceled, shall become exercisable in full for the
          remainder of the applicable term of such Options, and (ii) all
          restrictions applicable to all outstanding Options granted pursuant to
          the Plan shall be deemed to have been satisfied and such Options shall
          immediately vest in full.

     (c)  Except as otherwise provided in an Option agreement, upon the
          occurrence of a Change of Control (as defined in Section 6(d)), the
          Board may, in its sole discretion, provide for (i) the payment of a
          cash amount in exchange for the cancellation of an Option which may
          equal the excess, if any, of the fair market value of the shares
          subject to such Option, as defined in Section 5(a), over the aggregate
          exercise price of such Options or (ii) the issuance of substitute
          Option awards that will substantially preserve the value, rights and
          benefits of any affected Options previously granted hereunder.

     (d)  "Change of Control" means any one of the following:

          (i)  Individuals who, as of September 10, 2001, constitute the Board
               of Directors of the Company (the "Incumbent Board"), cease for
               any reason to constitute at least a majority of such Board;
               provided, however, that any individual becoming a director
               subsequent to the date hereof, whose election, or nomination for
               election by the Company's shareholders, was approved by a vote of
               at least a majority of the Incumbent Board shall be considered as
               though such individual were a member of the Incumbent Board, but
               excluding, for this purpose, any such individual whose initial
               assumption of the office occurs as a result of an actual or
               threatened election contest with respect to the election or
               removal of directors or other actual or threatened solicitation
               of proxies or consents by or on behalf of a "person" (as such
               term is defined in Section 13(d) or 14(d) of the Securities
               Exchange Act of 1934, as amended from time to time) other than
               the Incumbent Board; or

          (ii) Consummation by the Company of a reorganization, merger or
               consolidation or sale or other disposition of all or
               substantially all of the assets of the Company (a "Business
               Combination"), in each case, unless, following such Business
               Combination, (A) all or substantially all of the individuals and
               entities who were the beneficial owners, respectively, of the
               then outstanding Shares of the Company (or its successor by
               merger, consolidation or purchase of all or substantially all of
               its assets) (the "Outstanding Common Stock") and the combined
               voting power of the then outstanding voting securities of the
               Company (or its successor by merger, consolidation or purchase of
               all or substantially all of its assets) entitled to vote
               generally in the election of directors (the "Outstanding Voting
               Securities") immediately prior to such Business Combination
               beneficially own, directly or indirectly, more than 50% of,
               respectively, the then Outstanding Common Stock and the combined
               voting power of the then Outstanding Voting Securities, as the
               case may be, of the corporation resulting from such Business
               Combination (including, without limitation, a corporation which
               as a result of such transaction owns the Company or all or
               substantially all of the Company's assets either directly or
               through one or more subsidiaries) in substantially the same
               proportions as their ownership immediately prior to such Business
               Combination of the Outstanding Common Stock and Outstanding
               Voting Securities, as the case may be, and (B) at least a
               majority of the members of the board of directors of the

                                       5



                corporation resulting from such Business Combination were
                members of the Incumbent Board at the time of the execution of
                the initial agreement or of the action of such Incumbent Board
                providing for such Business Combination; or

          (iii) Approval by the shareholders of the Company of a complete
                liquidation or dissolution of the Company.

7. Miscellaneous Provisions

     (a)  Except as expressly provided for in the Plan, no Eligible Director or
          other person shall have any claim or right to be granted an Option
          under the Plan. Neither the Plan nor any action taken hereunder shall
          be construed as giving any Eligible Director any right to be retained
          in the service of the Company.

     (b)  Except as provided for under Section 5(d), an optionee's rights and
          interest under the Plan may not be assigned or transferred in whole or
          in part either directly or by operation of law or otherwise (except in
          the event of an optionee's death, by will or the laws of descent and
          distribution), including, but not by way of limitations, execution,
          levy, garnishment, attachment, pledge, bankruptcy or in any other
          manner, and no such right or interest of any participant in the Plan
          shall be subject to any obligation or liability of such participant.
          Any Options held by such assignee or transferee shall be subject to
          the terms of this Plan and the agreement pursuant to which such
          Options were granted.

     (c)  No Common Stock shares shall be issued hereunder unless counsel for
          the Company shall be satisfied that such issuance will be in
          compliance with applicable federal, state and other securities laws
          and regulations.

     (d)  It shall be a condition to the obligation of the Company to issue
          Common Stock shares upon exercise of an Option, that the optionee (or
          any beneficiary or person entitled to act under subparagraph 5(e)(iv)
          above) pay to the Company, upon its demand, such amount as may be
          requested by the Company for the purpose of satisfying any liability
          or obligation of the Company to withhold federal, state, local or
          foreign income or other taxes. If the amount requested is not paid,
          the Company may refuse to issue Common Stock shares.

     (e)  The expenses of the Plan shall be borne by the Company.

     (f)  The Plan shall be unfunded. The Company shall not be required to
          establish any special or separate fund or to make any other
          segregation of assets to assure the issuance of shares upon exercise
          of any Option under the Plan and issuance of shares upon exercise of
          Options shall be subordinate to the claims of the Company's general
          creditors.

     (g)  By accepting any Option or other benefit under the Plan, each optionee
          and each person claiming under or through such person shall be
          conclusively deemed to have indicated his acceptance and ratification
          of, and consent to, any action taken under the Plan by the Company or
          the Board.

                                       6



8. Amendment

The Plan may be amended at any time and from time to time by the Board as the
Board shall deem advisable, including, but not limited to amendments necessary
to qualify for any exemption or to comply with applicable law or regulations
provided, however, that except as provided in Paragraph 6 above, the Board may
not, without further approval by the shareholders of the Company in accordance
with Paragraph 10 below, increase the maximum number of shares of Common Stock
as to which Options may be granted under the Plan, increase the number of shares
subject to an Option, reduce the minimum Option exercise price described in
subparagraph 5(a) above, extend the period during which Options may be granted
or exercised under the Plan or change the class of persons eligible to receive
Options under the Plan. No amendment of the Plan shall materially and adversely
affect any right of any optionee with respect to any Option theretofore granted
without such optionee's written consent.

9. Termination

This Plan shall terminate upon the earlier of the following dates or events to
occur:
