Exhibit 10

Transition Agreement

This Transition Agreement (“Agreement”) is between Patterson Companies, Inc., on behalf of itself, its affiliated and related entities, and any of their respective direct or indirect subsidiaries (collectively referred to herein as the “Company” or “Patterson”), and Scott P. Anderson (referred to herein as “Executive”) (Patterson and Executive are collectively referred to herein as “Parties”). This Agreement is effective fifteen (15) days from the date on which it is signed by all Parties hereto (“Effective Date”).

WHEREAS, Executive has been employed as Patterson’s President and Chief Executive Officer;

WHEREAS, Executive also serves as a member of Patterson’s Board of Directors (“Board”) and as Patterson’s Chairman of the Board (“Chair”);

WHEREAS, Executive desires to (1) cease serving as Patterson’s President, Chief Executive Officer and Chair effective June 1, 2017, (2) refrain from standing for reelection to the Board at the Company’s 2017 Annual Meeting of Shareholders (the “Annual Meeting”), and (3) retire from his employment with Patterson effective July 1, 2019;

WHEREAS, the Parties agree that in the interim prior to Executive’s retirement Executive will remained employed at Patterson in a transitional role; and

WHEREAS, the Parties desire to set forth the terms under which Executive will be employed prior to his retirement;

NOW, THEREFORE, in consideration of the mutual covenants and promises herein contained and other good and valuable consideration, receipt of which is hereby acknowledged, it is hereby agreed by and between the Parties as follows:

The following terms shall apply during the Transition Period, conditioned upon Executive’s continued employment during that time:

2

exercisable as of such date, remain exercisable for a period of 90 days after such date (but in no event after the expiration date of any such NQSO). Pursuant to the terms of Executive’s Non-Qualified Stock Option Award Agreements, Executive agrees that any NQSOs that have not vested on or prior to the end of the Transition Period are forfeited and cancelled. For avoidance of doubt, Executive shall not receive any additional NQSOs.

Within 21 days after the end of the Transition Period, the Company shall transfer to Executive the service agreement for the cellular phone assigned to Executive, subject to Executive acknowledging and agreeing at that time that Executive has returned any electronic materials or property of the Company existing or stored on the cellular phone.

At the end of the Transition Period, Executive may retain the computer assigned to Executive, subject to Executive acknowledging and agreeing at that time that Executive has returned any electronic materials or property of the Company existing or stored on the computer.

3

In exchange for the payments and benefits promised to Executive in this Agreement, Executive agrees as follows:

4

In the event that Executive obtains new employment on or prior to June 30, 2020, Executive shall: (i) disclose this Agreement to his new employer prior to beginning the employment; and (ii) notify the Company of the identity of his new employer within seven (7) days after accepting any offer of employment by sending a written notification to the Company.

Executive agrees that the foregoing restrictions are in consideration of the payments received by Executive in accordance with this Agreement and that the restrictions are reasonable and necessary for the purpose of protecting Patterson’s legitimate business interests. Executive agrees that the scope of the business of the Company is independent of the location (such that it is not practical to limit the restrictions contained herein to a specific state, city or part thereof) and therefore acknowledges and agrees that the geographic scope of this restriction throughout the United States, Canada and the United Kingdom is reasonable and necessary.

Executive further agrees that the remedy of damages at law for breach by Executive of any of the covenants and obligations contained in this Agreement is an inadequate remedy. In recognition of the irreparable harm that a violation by Executive of the covenants and obligations in this Agreement would cause Patterson, or any company with which Patterson has a business relationship, Executive agrees that if he breaches or proposes to breach, any provision of this Agreement, Patterson shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such breach or proposed breach without showing or proving any actual damage to Patterson, it being understood by Executive and Patterson that both damages and equitable relief shall be proper modes of relief and are not to be considered alternative remedies.

The Confidential Information may be contained in written materials, such as documents, files, reports, manuals, drawings, diagrams, blueprints and correspondence, as well as computer hardware and software, and electronic or other form or media. It may also consist of unwritten knowledge, including ideas, research, processes, plans, practices and know-how.

Confidential Information does not include information that is in the public domain or information generally known in the trade, other than as a result of a disclosure by or through Executive in violation of this Agreement or by another person in breach of a confidentiality obligation. Further, information that Executive acquired completely independently of his employment with Patterson is not considered to be Confidential Information.

Executive agrees that he shall not, at any time, disclose or otherwise make available Confidential Information to any person, company or other party. Further, Executive shall not use or disclose any Confidential Information at any time without Patterson’s prior written consent. This Agreement shall not limit any obligations Executive has under any confidentiality agreement or applicable law.

6

Executive agrees that Patterson may open all mail (including but not limited to regular mail, electronic mail and voicemail) delivered to the Company and addressed to him.

Executive understands that he is giving up any and all claims, complaints, causes of action or demands of any kind that he has or may have for claims arising under or based on Title VII of the Civil Rights Act, the Equal Pay Act, Executive Order 11246, the Americans with Disabilities Act, The Genetic Information Nondiscrimination Act of 2008, the Employee Retirement Income Security Act (“ERISA”) with respect to unvested benefits, the Age Discrimination in Employment Act, the Family and Medical Leave Act, the Sarbanes-Oxley Act of 2002, the Worker Adjustment and Retraining Notification Act, the Uniform Services Employment and Reemployment Rights Act, the Minnesota Human Rights Act, any other state or local antidiscrimination, civil rights and human rights statutes, or any other federal state or local law which claims can be properly released through this Agreement. Executive further understands that this release

8

that the provisions of this Section III are an essential inducement to the Company to enter into this Agreement and they are in addition to, rather than in lieu of, any similar or related covenants to which Executive is a party or by which he is bound. Executive further acknowledges that the restrictions contained in this Section III shall not impose an undue hardship on him since he has general business skills which may be used in industries other than that in which the Company conducts its business and shall not deprive Executive of his livelihood. In exchange for Executive agreeing to be bound by these reasonable and necessary covenants, the Company is providing Executive with the benefits as set forth in this Agreement, including without limitation the compensation set forth in Section II. Employee acknowledges and agrees that these benefits constitute full and adequate consideration for his obligations hereunder and will be provided only if he signs and does not rescind this Agreement. Executive further acknowledges and agrees that in the event Executive is terminated for Cause prior to the Retirement Date, and therefore will not be paid the severance set forth in Section II(I), he remains bound by the provisions of this Section III. In the event Executive breaches the terms of this Section III, the severance and other payments made to Executive hereunder are subject to cessation and repayment as set forth in Section V(A) of this Agreement.

By executing the Agreement below, Executive confirms and acknowledges that he has reviewed the information about the offer described above and given to him as part of this Agreement. Executive further acknowledges that he has been granted twenty-one (21) days from the date he received this Agreement within which to consider this Agreement. Executive further acknowledges that by virtue of being presented with this Agreement, he is hereby advised in writing to consult with legal counsel prior to executing this Agreement. Executive acknowledges that if he executes this Agreement prior to the expiration of twenty-one (21) days, or chooses to forgo the advice of legal counsel, he has done so freely and knowingly, and he waives any and all future claims that such action or actions would affect the validity of this Agreement. Executive acknowledges that any changes made to this Agreement after its first presentation to him, whether material or immaterial, do not re-start the tolling of this twenty-one (21) day period.

Executive may cancel this Agreement at any time on or before the fifteenth (15th) day following the date on which he signs the Agreement to assert alleged claims under the Minnesota Human Rights Act. Executive also may cancel this Agreement at any time on or before the seventh (7th) day following the date on which he signs the Agreement to assert alleged claims under the Age Discrimination of Employment Act. To be effective, the decision to cancel must be in writing and delivered to the Company, personally or by certified mail, to the attention of the General Counsel, Patterson Companies, Inc., 1031 Mendota Heights Road, St. Paul, MN 55120 on or before the applicable fifteenth (15th) or seventh (7 ^th ) day after he signs the Agreement. If the release provisions of Section III are held invalid for any reason whatsoever, Executive agrees to return any consideration received under the terms of the Agreement to which he is not otherwise entitled absent this Agreement and that the Company is released from any obligations under the

9

Agreement. By accepting the payments described in Section II of this Agreement, Executive acknowledges that the revocation periods have expired and that he did not revoke this Agreement.

10

Executive’s termination of employment shall mean a “separation from service” within the meaning of Code Section 409A. Notwithstanding anything herein to the contrary, this Agreement shall, to the maximum extent possible, be administered, interpreted and construed in a manner consistent with Code Section 409A; provided, that in no event shall the Company have any obligation to indemnify the Executive from the effect of any taxes under Code Section 409A.
