 Exhibit 10.1 
 EMPLOYMENT AGREEMENT 
 THIS EMPLOYMENT AGREEMENT (this “Agreement”), made and entered into
by and between Les C. Vinney (“Vinney” or “Employee”) and STERIS Corporation, an Ohio corporation (“STERIS” or the “Company”), on the 7th day of September, 2006; 
 WITNESSETH: 
 WHEREAS, Vinney has
served the Company prior to the date of this Agreement (the “Effective Date”) in the capacities of Senior Vice President and Chief Financial Officer, Chief Operating Officer and, most recently, President and Chief Executive Officer; and

 WHEREAS, Vinney’s efforts since he joined the Company in March 2000 have contributed to the success of the Company and enhancement of
shareholder value; and 
 WHEREAS, Vinney and STERIS want to document an employment and succession plan for the orderly transition of
management responsibilities to effectuate Vinney’s eventual retirement and separation from the Company in accordance with previous discussions and mutual understandings; and 
 WHEREAS, STERIS desires to retain Vinney in an appropriate role until his retirement, to further enhance shareholder value, based on his value to the
Company; and 
 WHEREAS, Vinney and STERIS desire to enter into this Agreement to set forth their agreement concerning Vinney’s
continued employment and an orderly succession plan. 
 NOW, THEREFORE, in consideration of the mutual promises and covenants contained in
this Agreement, Vinney and STERIS agree as follows: 
 1. Employment. (a) From the Effective Date until the Changeover Date (as
defined below), Vinney shall be employed as President and Chief Executive Officer of the Company at the base salary of $726,000 per year. Vinney will also participate in the Company’s Senior Executive Management Incentive Compensation Plan (the
“SEMICP”) for the fiscal year ending March 31, 2007 at the levels and targets previously approved by the Compensation and Corporate Governance Committee of the Board of Directors of the Company (the “Compensation
Committee”), regardless of the Changeover Date. In that connection, Vinney will be paid the full bonus earned based on the attainment of previously approved corporate objectives and the other terms of the SEMICP for the year ended
March 31, 2007, except that the Compensation Committee will exercise any negative discretion as permitted by the SEMICP to reduce any amount payable to Vinney under the SEMICP only to the extent that Vinney does not facilitate the transition to
a new Chief Executive Officer or observe his obligation to cooperate as required by Section 16. STERIS will pay at least 75% of the estimated amount payable to Vinney under the SEMICP on or prior to June 1, 2007, with the remainder of any
such amount payable to Vinney in accordance with the terms of the SEMICP (provided that such remaining amount shall be paid in any event in compliance with Section 409A of the Internal Revenue Code (“Section 409A”)). As President and
Chief Executive Officer of the Company, Vinney shall have the normal executive and managerial responsibilities, duties and authority of an executive serving in such position, subject to the power of the Board of Directors to limit or expand such
responsibilities, duties and authorities and subject to the Company’s Code of Regulations and existing resolutions of the Board of Directors and committees thereof. 

 (b) On or before June 1, 2007, the Board of Directors intends to elect a new Chief Executive
Officer. The earlier of (i) the date on which the new Chief Executive Officer is elected or (ii) June 1, 2007 shall be referred to in this Agreement as the “Changeover Date.” In the event that the Changeover Date occurs
prior to June 1, 2007, Vinney shall continue to perform services through May 31, 2007 (the “Section 409A Separation Date”) as a senior executive employee, reporting to the new Chief Executive Officer and the Board of Directors of
the Company and performing such duties as may from time to time be assigned by the new Chief Executive Officer or the Board of Directors relating to assisting the new Chief Executive Officer with transition matters as well as assisting with respect
to the matters described in Section 16 of this Agreement and other similar projects. Vinney shall perform such duties on a regular and consistent basis, with the expectation that such duties will require services to be performed no less than
one quarter of Vinney’s customary average working hours for the three full immediately preceding calendar years prior to the Changeover Date. After any such Changeover Date, Vinney shall continue to receive his base salary at the rate of
$726,000 per year through the Section 409A Separation Date (unless his employment has been previously terminated pursuant to Section 13) and, if the Changeover Date occurs prior to the Section 409A Separation Date, shall also
participate in the SEMICP for the fiscal year ending March 31, 2007 as set forth in Section 1(a). Moreover, the Company shall continue to provide Vinney with an office and secretarial services as well as other accommodations and an
automobile allowance comparable to those provided to other senior executives of the Company and consistent with what the Company currently provides to Vinney through the Section 409A Separation Date, and Vinney will be entitled to participate
in STERIS’ insurance, retirement and other employee benefit programs as set forth in Section 3. 
 (c) From and after June 1,
2007 through the earlier of (i) May 31, 2009 or (ii) the date on which Vinney’s employment is terminated pursuant to Section 13 (the “Post-CEO Employment Period”), Vinney will continue as an employee serving as
Senior Advisor performing such duties on an as needed basis as may from time to time be assigned by the new Chief Executive Officer or the Board of Directors which do not unreasonably conflict with any other employment responsibilities of Vinney,
and the parties recognize that Vinney may have full-time employment elsewhere during this time period. 
 (d) The Company shall reimburse
Vinney for all reasonable expenses incurred by him in the course of performing his duties under this Agreement which are consistent with the Company’s policies in effect from time to time with respect to travel, entertainment and other business
expenses, subject to the Company’s requirements with respect to reporting and documentation of such expenses; provided, that reimbursement shall be made no later than 2 1/2 months after the end of the calendar year in which the expenses were incurred. The Company will continue to provide Vinney with voice mail and secretarial services through
December 31, 2007. 
 (e) Vinney shall be deemed to have resigned without any further action on his part, effective on the
Changeover Date, his position as President and Chief Executive Officer and as a member of the Board of Directors of the Company. In addition, Vinney shall be deemed to 
  

 - 2 - 

 have resigned without any further action on his part, effective on the Changeover Date, (i) from all other offices
of the Company to which he has been elected by the Board of Directors of the Company (or to which he has otherwise been appointed), (ii) from all offices of any entity that is a subsidiary of, or is otherwise related to or affiliated with, the
Company, (iii) from all administrative, fiduciary or other positions he may hold with respect to arrangements or plans for, of or relating to the Company or any subsidiary or other affiliate of the Company, and (iv) from any other
directorship, office, trustee or other position of any corporation, partnership, joint venture, trust or other enterprise (each, an “Other Entity”) insofar as Vinney is serving in the directorship, office, trustee or other position of the
Other Entity at the request of the Company; provided, however, that if such resignation results in noncompliance with any statute, rule or regulation applicable to any entity, subsidiary, other affiliate of the Company or Other Entity, such
resignation shall be effective at such time as the resignation would be in compliance with any such statute, rule or regulation. Vinney will not accept election or a nomination for election as a Director of the Company at any annual or special
meeting of shareholders after the date hereof. The Company hereby consents to and accepts such resignations. 
 (f) In the event that a
“change of control” with respect to the Company (as defined in applicable regulations under Section 409A) occurs prior to May 31, 2009, the Company shall pay to Vinney, within five days after such change of control, the full
remaining amount that would be payable to Vinney from and after the date of such change of control through May 31, 2009 under this Agreement except for COBRA and other benefits, which will be paid according to the respective plans. 

2. Stock Options. All of Vinney’s stock options, which are listed on Exhibit A hereto, shall remain outstanding to the extent of
their original term with exercisability extending to three months after the end of Vinney’s continued employment described in this Agreement but not later than the latest date permitted by applicable regulations under Section 409A, all in
accordance with and subject to the terms of the STERIS Corporation 1997 Stock Option Plan, the STERIS Corporation 1998 Long-Term Incentive Plan, the STERIS Corporation 2002 Stock Option Plan, as amended, and the STERIS Corporation 2006 Long-Term
Equity Incentive Plan (collectively, the “Option Plans”), as applicable, and the applicable notice of grant or other option agreement, including, without limitation, the Nonqualified Stock Option Agreement dated August 2, 1999, except
that (a) Vinney and the Company agree that with respect to the 25,000 shares under option 001450, the 50,000 shares under option 001803 and the 75,000 shares under option number 02209 for which those options were not exercisable on
January 1, 2005, those options will be exercisable only through December 31, 2007 and (b) the exercisability of the option described in part D of Exhibit A shall be as set forth in the evidence of award relating to such option. The
parties understand that to the extent that Vinney’s continued employment after May 31, 2007 as described in this Agreement affects the Employment Termination Date of options 002591 and 002998 those options may be deemed to be extended for
purposes of Section 409A, but the parties recognize that such options would not thereby become deferred compensation subject to Section 409A because the exercise price of those options exceeds the fair market value of the Company’s
common stock on the date of this Agreement. 
 3. Continuation of Health Insurance and Other Employment Benefits. (a) From the
date of this Agreement until the day immediately prior to the 409A Separation Date 
  

 - 3 - 

 and (b) for the period beginning on the Section 409A Separation Date and ending on the earliest of (i) the
date on which Vinney accepts full-time employment elsewhere, (ii) the date on which Vinney’s employment is terminated pursuant to Section 13 or (iii) May 31, 2009, Vinney will be entitled to continue to participate in
STERIS’ insurance, retirement and other employee benefit programs (including matching contributions to the Company’s 401(k) Savings Plan) to the same extent as he was entitled to participate prior to the date of this Agreement, except that
in the case of the period referred to in clause (b) above, Vinney will elect COBRA coverage, and the Company will reimburse Vinney for the costs of such coverage, until the earlier of the expiration of COBRA coverage or until Vinney accepts
full-time employment elsewhere. In the event that Vinney does not accept full-time employment elsewhere before the expiration of COBRA coverage, the Company will reimburse Vinney for his medical insurance premium expenses after the expiration of
COBRA coverage to the same extent the Company would provide coverage under its health insurance plan until the earlier of December 31, 2009 or the date Vinney accepts full-time employment elsewhere. 
 4. Post-CEO Employment Period Payments. Subject to Vinney’s observance of all terms and conditions set forth in this Agreement, unless his
employment has been previously terminated pursuant to Section 13, the Company shall pay Vinney the following amounts: 
 (a) $375,000
payable on December 1, 2007; and 
 (b) Eighteen installments of $62,500 each payable on the last day of each month commencing
December 31, 2007 and ending May 31, 2009. 
 In the event of Vinney’s death prior to May 31, 2009 these amounts will be paid to his
designated beneficiaries, or if none, to his estate. On May 31, 2009, Vinney shall retire from employment with the Company. 
 5.
Attorneys’ Fees. On or about the Effective Date, STERIS shall pay Vinney’s counsel fees for legal services provided to Vinney in connection with the negotiation and preparation of this Agreement, but not an amount in excess of
$45,000. 
 6. Review of Announcements/Disclosures. Except as required by applicable law, no press releases or any other public or
internal announcements regarding this Agreement or the actions contemplated hereunder shall be made by any party to this Agreement without the prior review and approval of the other party, which approval shall not be unreasonably withheld.

 7. Personal Effects. After the Section 409A Separation Date, at no cost to Vinney, Vinney shall be entitled to remove and
retain his office furniture and furnishings and equipment including, but not limited to, his computers, printers, fax machines, blackberry portable phone, awards and personal possessions; provided, however, that the Company shall be entitled to
examine Vinney’s computers and remove any software, electronic files and all other property of the Company, including, without limitation, property, documents and/or all other materials (including copies, reproductions, summaries and/or
analyses) which constitute, refer or relate to Confidential Information (as defined in Section 10 below) of the Company or any software or files belonging to the Company or otherwise containing any Confidential Information.

 8. Competition. (a) During the period beginning on the 409A Separation Date and ending on the
two-year anniversary of the date on which Vinney’s employment with STERIS is terminated (the “Restricted Period”), Vinney shall not, directly or indirectly, do or suffer to be done any of the following: perform any advisory or
consulting services for, operate or invest in (other than not more than one percent of the stock in a publicly-held corporation which is traded on a recognized securities exchange or over-the-counter), be employed by or an independent contractor of,
or be a director, partner, or officer of, or otherwise become associated with in any capacity, any person, firm, corporation, partnership, proprietorship, or other entity that develops, manufactures, assembles, sells, distributes, or performs
products, systems or services in competition with any products, systems, or services developed, manufactured, assembled, sold, distributed, or performed by the Company. 
 (b) Vinney has carefully considered the nature and extent of the restrictions upon him and the rights and remedies conferred upon the Company under this Section 8 and this Agreement, and hereby acknowledges and
agrees that the same are reasonable in time and territory, are designed to eliminate competition which otherwise would be unfair to the Company, do not stifle the inherent skill and experience of Vinney, would not operate as a bar to Vinney’s
sole means of support, are fully required to protect the legitimate interests of the Company and do not confer a benefit upon the Company disproportionate to the detriment to Vinney. Vinney further acknowledges that his obligations in this
Section 8 are made in consideration of, and are adequately supported by the payments by the Company to Vinney described in this Agreement. 
 9. No Solicitation of Employees. Vinney agrees that he will not, at any time, without the prior written consent of the Company, directly or indirectly, induce or attempt to induce any employee, agent, or other representative or

strict confidence, and will not, directly or indirectly, at any time, disclose, furnish, disseminate, make available, use or suffer to be used in any manner any Confidential Information of the Company without limitation as to when or how Vinney may
have acquired such Confidential Information. Vinney specifically acknowledges that Confidential Information includes any and all information, whether reduced to writing (or in a form from which information can be obtained, translated, or derived
into reasonably usable form), or maintained in the mind or memory of Vinney and whether compiled or created by the Company, which derives independent economic value from not being readily known to or ascertainable by proper means by others who can
obtain economic value from the disclosure or use of such information, that reasonable efforts have been put forth by the Company to maintain the secrecy of confidential or proprietary or trade secret information, that such information is and will
remain the sole property of the Company, and that any retention or use by Vinney of confidential or proprietary or trade secret information after the termination of Vinney’s employment with and services for the Company shall constitute a

Section 7, Vinney will immediately return to the Company (to the extent he has not already returned), equipment, software, electronic files and all other property of the Company, including, without limitation, property, documents and/or all
other materials (including copies, reproductions, summaries and/or analyses) which constitute, refer or relate to Confidential Information of the Company.

(i) such Confidential Information of the Company shall have become, through no fault of Vinney, generally available to or known by the public, (ii) Vinney makes such disclosure in furtherance of the Company’s business and the
disclosure is authorized by the Board of Directors or the Chief Executive Officer of the Company, or (iii) Vinney is required by law (after providing the Company with notice and opportunity to contest such requirement) to make disclosure.

During the Restricted Period, Vinney shall not, and shall cause his affiliates not to, except within the terms of a specific written consent of the Chairman of the Compensation Committee, propose, discuss or have any communication with any other
person, directly or indirectly, relating in any way to (i) any form of business combination, acquisition or other transaction relating to the Company or any affiliate of the Company and any other party or any affiliate of any other party,
(ii) any form of restructuring, recapitalization or similar transaction with respect to the Company or any affiliate of the Company, or (iii) any demand, request or proposal (1) to acquire, or offer, propose or agree to acquire, by
purchase or otherwise, any common shares of the Company (“Voting Securities”), (2) to make, or in any way participate in, any solicitation of proxies with respect to any such Voting Securities of the Company (including, without
limitation, by the execution of action by written consent), become a participant in any election contest with respect to the Company or seek to influence any person with respect to any such Voting Securities, (3) to participate in or encourage

of any expenses and damages incurred as a result of the breach (including, without limitation, reasonable attorneys’ fees), with the remainder of this Agreement, and all promises and covenants in this Agreement, remaining in full force and
effect; provided, however, the Company will not terminate pursuant to this Section 13(a) any benefits in which Vinney had vested under the Company’s 401(k) Savings Plan, nor will Vinney’s COBRA rights, if any, be reduced by any action

 (b) Vinney acknowledges and agrees that the remedy at law available to the Company for
breach by Vinney of any of his obligations under Sections 8, 9, 10, 12 and 20 of this Agreement would be inadequate and that damages flowing from such a breach would not readily be susceptible to being measured in monetary terms. Accordingly, Vinney
acknowledges, consents and agrees that, in addition to any other rights or remedies which the

provision of Sections, 8, 9, 10, 12 and 20 of this Agreement, the Company shall be entitled to immediate injunctive relief and may obtain a temporary order restraining any threatened or further breach, without the necessity of proof of actual
damage.

notice to the Company and opportunity to cure, exercise all rights and remedies which Vinney may have, and the Company shall reimburse Vinney for any costs and expenses (including, without limitation, attorneys’ fees) reasonably incurred in
connection therewith.

the right, in addition to all other rights and remedies provided by law, at such party’s election, to seek arbitration in Cleveland, Ohio, under the rules of the American Arbitration Association, as to claims pursued by such party, by serving a
notice to arbitrate upon the other party. Notwithstanding the foregoing, the parties shall have the same rights of discovery under the Ohio Rules of Civil Procedure as if the dispute had been filed as an original action in an Ohio court of original
jurisdiction.

 CONFIDENTIAL TREATMENT REQUEST

 TO A CONFIDENTIAL TREATMENT REQUEST AND THIS INFORMATION 
 HAS BEEN FILED UNDER SEPARATE COVER WITH THE COMMISSION 
 Tatum, LLC 
 Interim Executive Services Agreement 
 August 25, 2006

 Ira J. Tabankin 
 Chairman and CTO 
 Catcher Holdings, Inc. 
 38881 Irish Corner Road 
 Lovettsville, VA 20180 
 Dear Mr. Tabankin: 
 Tatum, LLC (“Tatum”) understands that Catcher Holdings, Inc. (“the Company”) desires to engage a partner of Tatum to serve as interim chief financial
officer. This Interim Executive Services Agreement sets forth the conditions under which such services will be provided. 
 Services; Fees 
 Tatum will make available to the Company Debra R. Hoopes (the “Tatum Partner”), who will serve as chief financial
officer of the Company. The Tatum Partner will become an employee and a duly elected or appointed officer of the Company and subject to the supervision and direction of the CEO of the Company, the board of directors of the Company, or both.
Tatum will have no control or supervision over the Tatum Partner. 
 The Company will pay the Tatum Partner directly a salary of $20,000 a month
(“Salary”). In addition, the Company will pay directly to Tatum a fee of $5,000 a month (“Fees”) as partial compensation for resources provided. 
 The Company will have no obligation to provide the Tatum Partner any health or major medical benefits, stock, or bonus payments. The Tatum Partner will remain on his or her current medical plan. The Company will have
no obligation to provide the Tatum Partner any stock or bonus payments. In lieu of the Tatum Partner participating in the Company-sponsored employee medical insurance benefit plan, the Tatum Partner will remain on his or her current medical plan.

 As an employee, the Tatum Partner will be eligible for any Company employee retirement and/or 401(k) plan and for vacation and holidays consistent with
the Company’s policy as it applies to senior management, and the Tatum Partner will be exempt from any non-statutory delay periods otherwise required for eligibility. 
 Payments; Deposit 
 Payments to Tatum
should be made by direct deposit through the Company’s payroll, or by an automated clearing house (“ACH”) payment at the same time as payments are made to the Employee. If such payment method is not available and payments are made by
check, Tatum will issue invoices to the Company, and the Company agrees to pay such invoices no later than ten (10) days after receipt of invoices. 
 The Company will reimburse the Tatum Partner directly for out-of-pocket expenses incurred by the Tatum Partner in providing services hereunder to the same extent that the Company is responsible for such expenses of senior managers of the
Company. 
  

					
		  	Page 1 of 5	  	

 Company agrees to pay Tatum and to maintain a security deposit of $25,000 (one month’s fees) for the Company’s
future payment obligations to both Tatum and the Tatum Partner under this agreement (the “Deposit”). If the Company breaches this agreement and fails to cure such breach as provided in this agreement, Tatum will be entitled to apply the
Deposit to its damages resulting from such breach. Upon termination or expiration of this agreement, Tatum will return to the Company the balance of the Deposit remaining after application of any amounts to unfulfilled payment obligations of the
Company to Tatum or the Tatum Partner as provided for in this agreement. 
 Converting Interim to Permanent

 The Company will have the opportunity to make the Tatum Partner a permanent member of Company management at any time during the term of this agreement
by entering into another form of Tatum agreement, the terms of which will be negotiated at such time. 
 Hiring Tatum
Partner Outside of Agreement 
 During the twelve (12)-month period following termination or expiration of this agreement, other than in connection with
another Tatum agreement, the Company will not employ the Tatum Partner, or engage the Tatum Partner as an independent contractor, to render services of substantially the same nature as those to be performed by the Tatum Partner as contemplated by
this agreement. The parties recognize and agree that a breach by the Company of this provision would result in the loss to Tatum of the Tatum Partner’s valuable expertise and revenue potential and that such injury will be impossible or very
difficult to ascertain. Therefore, in the event this provision is breached, Tatum will be entitled to receive as liquidated damages an amount equal to forty-five percent (45%) of the Tatum Partner’s Annualized Compensation (as defined
below), which amount the parties agree is reasonably proportionate to the probable loss to Tatum and is not intended as a penalty. If, however, a court or arbitrator, as applicable, determines that liquidated damages are not appropriate for such
breach, Tatum will have the right to seek actual damages. The amount will be due and payable to Tatum upon written demand to the Company. For this purpose, “Annualized Compensation” will mean monthly Salary equivalent to what the Tatum
Partner would receive on a full-time basis multiplied by twelve (12), plus the maximum amount of any bonus for which the Tatum Partner was eligible with respect to the then current bonus year. 
 Term & Termination 
 Effective upon thirty (30) days’ advance written notice, either party may terminate this agreement, such termination to be effective on the date specified in the notice, provided that such date is no earlier than thirty
(30) days after the date of delivery of the notice. Tatum will continue to render services and will be paid during such notice period. 
 Tatum retains
the right to terminate this agreement immediately if (1) the Company is engaged in or asks the Tatum Partner to engage in or to ignore any illegal or unethical activity, (2) the Tatum Partner dies or becomes disabled, (3) the Tatum
Partner ceases to be a partner of Tatum for any other reason, or (4) upon written notice by Tatum of non-payment by the Company of amounts due under this agreement. For purposes of this agreement, disability will be as defined by the applicable
policy of disability insurance or, in the absence of such insurance, by Tatum’s management acting in good faith. 
  

					
		  	Page 2 of 5	  	

 In the event that either party commits a breach of this agreement, other than for reasons described in the above
paragraph, and fails to cure the same within seven (7) days following delivery by the non-breaching party of written notice specifying the nature of the breach, the non-breaching party will have the right to terminate this agreement immediately
effective upon written notice of such termination. 
 Insurance 
 The Company will provide Tatum or the Tatum Partner with written evidence that the Company maintains directors’ and officers’ insurance in an amount reasonably
acceptable to the Tatum Partner at no additional cost to the Tatum Partner, and the Company will maintain such insurance at all times while this agreement remains in effect. Furthermore, the Company will maintain such insurance coverage with
respect to occurrences arising during the term of this agreement for at least three years following the termination or expiration of this agreement or will purchase a directors’ and officers’ extended reporting period, or “tail,”
policy to cover the Tatum Partner. 
 Disclaimers, Limitations of Liability & Indemnity 
 Tatum assumes no responsibility or liability under this agreement other than to render the services called for hereunder and will not be responsible for any action taken
by the Company in following or declining to follow any of Tatum’s advice or recommendations. Tatum represents to the Company that Tatum has conducted its standard screening and investigation procedures with respect to the Tatum Partner becoming
a partner in Tatum, and the results of the same were satisfactory to Tatum. Tatum disclaims all other warranties, either express or implied. Without limiting the foregoing, Tatum makes no representation or warranty as to the accuracy or reliability
of reports, projections, forecasts, or any other information derived from use of Tatum’s resources, and Tatum will not be liable for any claims of reliance on such reports, projections, forecasts, or information. Tatum will not be liable for
any non-compliance of reports, projections, forecasts, or information or services with federal, state, or local laws or regulations. Such reports, projections, forecasts, or information or services are for the sole benefit of the Company and not any
unnamed third parties. 
 In the event that any partner of Tatum (including without limitation the Tatum Partner to the extent not otherwise entitled in his
or her capacity as an officer of the Company) is subpoenaed or otherwise required to appear as a witness or Tatum or such partner is required to provide evidence, in either case in connection with any action, suit, or other proceeding initiated by a
third party or by the Company against a third party, then the Company shall reimburse Tatum for the costs and expenses (including reasonable attorneys’ fees) actually incurred by Tatum or such partner and provide Tatum with compensation at
Tatum’s customary rate for the time incurred. 
 The Company agrees that, with respect to any claims the Company may assert against Tatum in connection
with this agreement or the relationship arising hereunder, Tatum’s total liability will not exceed two (2) months of Fees. 
 As a condition for
recovery of any liability, the Company must assert any claim against Tatum within three (3) months after discovery or sixty (60) days after the termination or expiration of this agreement, whichever is earlier. 
  

					
		  	Page 3 of 5	  	

 Tatum will not be liable in any event for incidental, consequential, punitive, or special damages, including without
limitation, any interruption of business or loss of business, profit, or goodwill. 
 Arbitration 
 If the parties are unable to resolve any dispute arising out of or in connection with this agreement, either party may refer the dispute to arbitration by a single
arbitrator selected by the parties according to the rules of the American Arbitration Association (“AAA”), and the decision of the arbitrator will be final and binding on both parties. Such arbitration will be conducted by the Washington,
D.C. office of the AAA. In the event that the parties fail to agree on the selection of the arbitrator within thirty (30) days after either party’s request for arbitration under this paragraph, the arbitrator will be chosen by AAA. The
arbitrator may in his discretion order documentary discovery but shall not allow depositions without a showing of compelling need. The arbitrator will render his decision within ninety (90) days after the call for arbitration. The arbitrator
will have no authority to award punitive damages. Judgment on the award of the arbitrator may be entered in and enforced by any court of competent jurisdiction. The arbitrator will have no authority to award damages in excess or in contravention of
this agreement and may not amend or disregard any provision of this agreement, including this paragraph. Notwithstanding the foregoing, either party may seek appropriate injunctive relief from a court of competent jurisdiction, and either party may
seek injunctive relief in any court of competent jurisdiction. 
 Miscellaneous 
 Tatum will be entitled to receive all reasonable costs and expenses incidental to the collection of overdue amounts under this Resources Agreement, including but not
limited to attorneys’ fees actually incurred. 
 The Company agrees to allow Tatum to use the Company’s logo and name on Tatum’s website and
other marketing materials for the sole purpose of identifying the Company as a client of Tatum. Tatum will not use the Company’s logo or name in any press release or general circulation advertisement without the Company’s prior written
consent. 
 Neither the Company nor Tatum will be deemed to have waived any rights or remedies accruing under this agreement unless such waiver is in writing
and signed by the party electing to waive the right or remedy. This agreement binds and benefits the respective successors of Tatum and the Company. 
 Neither party will be liable for any delay or failure to perform under this agreement (other than with respect to payment obligations) to the extent such delay or failure is a result of an act of God, war, earthquake, civil disobedience,
court order, labor dispute, or other cause beyond such party’s reasonable control. 
 The provisions concerning payment of compensation and
reimbursement of costs and expenses, limitation of liability, directors’ and officers’ insurance, and arbitration will survive the expiration or any termination of this agreement. 
 This agreement will be governed by and construed in all respects in accordance with the laws of the State of Virginia, without giving effect to conflicts-of-laws
principles.

 The terms of this agreement are severable and may not be amended except in writing signed by the party to be bound. If
any portion of this agreement is found to be unenforceable, the rest of the agreement will be enforceable except to the extent that the severed provision deprives either party of a substantial benefit of its bargain. 
 Nothing in this agreement shall confer any rights upon any person or entity other than the parties hereto and their respective successors and permitted assigns and the
Tatum Partner. 
 Each person signing below is authorized to sign on behalf of the party indicated, and in each case such signature is the only one
necessary.
