Executive acknowledges that Company and its Affiliates are engaged in business throughout the United States, as well as in other countries and
that the marketplace for Company’s and its Affiliates’ products and services is worldwide. Executive further covenants and agrees that the geographic, length of term and types of activities restrictions (non-competition restrictions)
contained in this Agreement are reasonable and necessary to protect the legitimate business interests of Company and its Affiliates because of the scope of Company’s and the Affiliates’ businesses. 

In the event that a court of competent jurisdiction shall determine that one or more of the provisions of this Paragraph 6 is so broad as to
be unenforceable, then such provision shall be deemed to be reduced in scope or length, as the case may be, to the extent required to make this Paragraph enforceable. If the Executive violates the provisions of this Paragraph 6, the periods
described therein shall be extended by that number of days which equals the aggregate of all days during which at any time any such violations occurred. Executive acknowledges that the offer of employment under this Agreement, or any other
consideration offered for signing this agreement, is sufficient consideration for Executive’s agreement to the restrictive covenants set forth in this Paragraph 6, and that each Affiliate is an intended third-party beneficiary of such covenants
with a separate and independent right to enforce the same. Executive agrees that Executive’s signing of an Employment Agreement containing the restrictive covenants set forth herein was a condition precedent to Executive’s continued
employment with Company. 

 7. NONDISCLOSURE AND NONUSE OF CONFIDENTIAL INFORMATION. The Executive covenants and
agrees during Executive’s employment or any time after the termination of such employment, not to communicate or divulge to any person, firm, corporation or business entity, either directly or indirectly, and to hold in strict confidence for
the benefit of Company, all Confidential Information except that Executive may disclose such Information to persons, firms or corporations who need to know such Information during the course and within the scope of Executive’s employment.
Executive will not use any Confidential Information for any purpose or for Executive’s personal benefit other than in the course and within the scope of Executive’s employment. Executive agrees to sign and abide by the terms and conditions
of Company’s Confidential Information and Intellectual Property Protection Agreement, a copy of which is attached hereto as Schedule B and incorporated as though fully set forth herein. 

8. TERMINATION. This Agreement may be terminated by either party with or without cause under the following conditions: 

(a) With Cause Termination. Executive may be terminated by Parent or Company with “cause.” “Cause” shall mean

duties as reasonably directed by the Company’s Board of Directors or Chief Executive Officer, or (vi) any material breach of paragraph 6 or 7 of this Agreement, or Executive’s Confidential Information and Intellectual Property

obligations under this Agreement including, but not limited to Paragraphs 6 and 7, in the event that Executive is terminated with Cause. 

(b) Without Cause. In the event that Executive’s employment is terminated by Company or Parent without Cause, Executive will be
entitled to the following. 
 (1) A number of months set forth below (the “Severance Period”) of Executive’s
last monthly base salary as set forth in the latest issued Schedule A, less appropriate deductions, payable following Executive’s termination of employment in accordance with the Company’s regular payroll practices (“Severance
Pay”): 
 a. Three (3) months, if termination occurs prior to the six-month anniversary of the effective date of
this Agreement. 
 b. Twelve (12) months, if termination occurs on or after the six-month anniversary of the effective
date of this Agreement. 

 Severance Pay will be treated as amounts paid under the Company’s generally
applicable severance pay policy (“Severance Policy”) as in effect from time to time to the extent of Executive’s entitlement to payments under the Severance Policy. Notwithstanding any other provision in this Agreement to the
contrary, in the event that the Severance Pay, when combined with other severance payments pursuant to the Agreement, exceed the maximum amount of severance pay permitted to be paid to a “specified employee” under Internal Revenue Code
§409A, the excess Severance Pay shall be paid instead in a single lump sum on the first business day after the end of the six (6)-month period. 

(2) Continued coverage under Company’s employee benefit plans (other than 401(k) or pension benefit coverage) and group
health plans (medical, dental and vision after termination of employment for Executive and his eligible dependents, as and when provided under the Severance Policy, and subject to the payment of applicable premiums or other costs, all in accordance
with the terms of the Severance Policy and the applicable benefit plans (including, without limitation, cessation of such benefits due to receiving similar benefit coverage from a new employer) with such modifications as are necessary to comply with
federal COBRA requirements. 
 (3) For the Severance Period, continued vesting in unvested stock options outstanding as of
such termination date and granted under the Company’s Stock Incentive Plan (the “Stock Plan”), or any successor thereto (the “Options”). 

(4) The exercise period for a vested Option, including those which vest pursuant to (5) above, will be extended for a
period equal to the Severance Period, but not later than the earlier of (i) the original expiration date of such Option or (ii) ten (10) years from the date of grant. 

Executive further acknowledges that the Company’s and Parent’s obligations under this Section 8(b), are contingent upon and
subject to Executive’s signing (and not revoking) an agreement and release of all claims against Company and Affiliates in the form attached hereto as Schedule C (or such other form acceptable to Company or Parent) within thirty (30) days
of the date of termination without Cause. Executive acknowledges that Executive has continuing obligations under this Agreement including, but not limited to Paragraphs 6 and 7, in the event that Executive is terminated without Cause. 

(c) Termination for convenience by Executive. Executive agrees to provide Company with three (3) months written notice in the event
Executive elects to terminate employment with Company for the convenience of Executive. In the event that Executive terminates for convenience, Executive agrees that no further wages, benefits or other compensation hereunder is payable to Executive
after the day in which Executive is last employed by Company. Executive acknowledges that Executive has continuing obligations under this Agreement including, but not limited to Paragraphs 6 and 7, in the event that Executive elects to terminate for
convenience. 

 9. TERM. Executive’s employment shall continue from year to year or until such
employment is terminated in accordance with the provisions of Paragraph 8. Executive acknowledges and agrees that nothing herein guarantees Executive continued employment by Company for any specified or intended term, and that his employment may be
terminated by Company at any time. 
 10. EQUITABLE RELIEF; FEES AND EXPENSES. Executive stipulates and agrees that any breach of
this Agreement by Executive will result in immediate and irreparable harm to Company and its Affiliates, the amount of which will be extremely difficult to ascertain, and that Company and its Affiliates could not be reasonably or adequately
compensated by damages in an action at law. For these reasons, Company and its Affiliates shall have the right to obtain such preliminary, temporary or permanent injunctions or restraining orders or decrees as may be necessary to protect Company or
any Affiliate against, or on account of, any breach by Executive of the provisions of this Agreement without the need to post bond. Such right to equitable relief is in addition to all other legal remedies Company or any Affiliate may have to
protect its rights. The prevailing party in any such action shall be responsible for reimbursing the non-prevailing party for all costs associated with obtaining the relief, including reasonable attorneys’ fees, and expenses and costs of suit.
Executive further covenants and agrees that any order of court or judgment obtained by Company or an Affiliate which enforces Company’s or Affiliate’s rights under this Agreement may be transferred, without objection or opposition by
Executive, to any court of law or other appropriate law enforcement body located in any other state in the U.S.A. or any other country in the world where Company or such Affiliate does business, and that said court or body shall give full force and
effect to said order and or judgment. 
 11. EMPLOYMENT DISPUTE SETTLEMENT PROCEDURE-WAIVER OF RIGHTS. In consideration of Company
employing Executive and the wages and benefits provided under this Agreement, Executive and Company each agree that, in the event either party (or its representatives, successors or assigns) brings an action in a court of competent jurisdiction
relating to Executive’s recruitment, employment with, or termination of employment from Company, the plaintiff in such action agrees to waive his, her or its right to a trial by jury, and further agrees that no demand, request or motion will be
made for trial by jury. 
 In consideration of Company employing Executive and the wages and benefits provided under this Agreement,
Executive further agrees that, in the event that Executive seeks relief in a court of competent jurisdiction for a dispute covered by this Agreement, Company may, at any time within 60 days of the service of Executive’s complaint upon Company,
at its option, require all or part of the dispute to be arbitrated by one arbitrator in accordance with the rules of the American Arbitration Association. Executive agrees that the option to arbitrate any dispute is governed by the Federal
Arbitration Act, and is fully enforceable. Executive understands and agrees that, if Company exercises its option, any dispute arbitrated will be heard solely by the arbitrator, and not by a court. The parties agree that the prevailing party shall
be entitled to have all of their legal fees paid by the non-prevailing party. This pre-dispute resolution agreement will cover all matters directly or indirectly related to Executive’s recruitment, employment or termination of employment by
Company; including, but not limited to, claims involving laws against any form of discrimination whether brought under federal and/or state law, and/or claims involving co-employees, but excluding Worker’s Compensation Claims. 

 THE RIGHT TO A TRIAL, AND TO A TRIAL BY JURY, IS OF VALUE. YOU MAY WISH TO CONSULT AN
ATTORNEY PRIOR TO SIGNING THIS AGREEMENT. IF SO, TAKE A COPY OF THIS AGREEMENT WITH YOU. HOWEVER, YOU WILL NOT BE OFFERED EMPLOYMENT UNDER THIS AGREEMENT UNTIL THIS AGREEMENT IS SIGNED AND RETURNED BY YOU. 

12. AMENDMENTS. No supplement, modification, amendment or waiver of the terms of this Agreement shall be binding on the parties hereto
unless executed in writing by the party to be bound thereby. No waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provisions hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided. Any failure to insist upon strict compliance with any of the terms and conditions of this Agreement shall not be deemed a waiver of any such terms or conditions.

skill, energy and attention exclusively to the business of Company and to comply with all rules, regulations and procedures of Company. During the term of this Agreement, Executive will not engage in any other business for Executive’s own
account or accept any employment from any other business entity, or render any services, give any advice or serve in a consulting capacity, whether gratuitously or otherwise, to or for any other person, firm or corporation, other than as a volunteer
for charitable organizations, without the prior written approval of Company, which shall not be unreasonably withheld. Executive’s duties shall be performed at Company’s offices in Pittsburgh, Pennsylvania, reasonable periods of business
travel excepted. 
 3. COMPENSATION. Executive’s compensation as of the date of this Agreement is as set forth on Schedule
A hereto. Company shall be entitled to withhold from any payments to Executive pursuant to the provisions of this Agreement any amounts required by any applicable taxing or other authority, or any amounts payable by Executive to Company or any
Affiliate (including, without limitation, repayment of any amount loaned to Executive by Company or any Affiliate). 
 4. BENEFITS.
Executive is eligible for the standard Company benefits, which may be modified by Company at any time or from time to time in accordance with the terms of Company’s applicable benefit plans and policies. Executive shall also be entitled to
reimbursement of business-related expenses in accordance with Company’s standard policies concerning reimbursement of such expenses. 

5. POLICIES AND PRACTICES. Executive agrees to abide by all Company rules, regulations, policies, practices and procedures, of which he
shall be given notice by Company, which Company may amend from time to time. 
 6. AGREEMENT NOT TO COMPETE. In order to protect the
business interests and goodwill of Company and its Affiliates with respect to Customers and accounts, and to protect Confidential Information, Executive covenants and agrees that for the entire period of Executive’s employment, and for a period
of one (1) year after termination of Executive’s employment for any reason, Executive will not: 
 (a) directly or indirectly
contact any Customer for the purpose of soliciting such Customer to purchase, lease or license a product or service that is the same as, similar to, or in competition with those products and/or services made, rendered, offered or under development
by Company or any Affiliate; 

  
 - 3 - 

 (b) directly or indirectly employ, or knowingly permit any company or business directly or
indirectly controlled by Executive to employ any person who is employed by Company or any Affiliate at any time during the term of Executive’s employment, or in any manner facilitate the leaving of any such person from his or her employment
with Company or any Affiliate; 
 (c) directly or indirectly interfere with or attempt to disrupt the relationship, contractual or
otherwise, between Company or any Affiliate and any of its employees or solicit, induce, or attempt to induce employees of Company or any Affiliate to terminate employment with Company or Affiliate and become self-employed or employed with others in
the same or similar business or any product line or service provided by Company or any Affiliate; or 
 (d) directly or indirectly engage in
any activity or business as a consultant, independent contractor, agent, employee, officer, partner, director or otherwise, alone or in association with any other person, corporation or other entity, in any Competing Business operating within the
United States or any other country. 
 Executive acknowledges that Company and its Affiliates are engaged in business throughout the United
States, as well as in other countries and that the marketplace for Company’s and its Affiliates’ products and services is worldwide. Executive further covenants and agrees that the geographic, length of term and types of activities
restrictions (non-competition restrictions) contained in this Agreement are reasonable and necessary to protect the legitimate business interests of Company and its Affiliates because of the scope of Company’s and the Affiliates’
businesses. 
 In the event that a court of competent jurisdiction shall determine that one or more of the provisions of this Paragraph 6 is
so broad as to be unenforceable, then such provision shall be deemed to be reduced in scope or length, as the case may be, to the extent required to make this Paragraph enforceable. If Executive violates the provisions of this Paragraph 6, the
periods described therein shall be extended by that number of days which equals the aggregate of all days during which at any time any such violations occurred. Executive acknowledges that the offer of employment by Company, or any other
consideration offered for signing this agreement, is sufficient consideration for Executive’s agreement to the restrictive covenants set forth in this Paragraph 6, and that each Affiliate is an intended third-party beneficiary of such covenants
with a separate and independent right to enforce the same. Executive agrees that Executive’s signing of an employment agreement containing the restrictive covenants set forth herein was a condition precedent to Executive’s continued
employment with Company. 
 7. NONDISCLOSURE AND NONUSE OF CONFIDENTIAL INFORMATION. Executive covenants and agrees during
Executive’s employment or any time after the termination of such employment, not to communicate or divulge to any person, firm, corporation or business entity, either directly or indirectly, and to hold in strict confidence for the benefit of
Company, all Confidential Information except that Executive may disclose such Confidential Information to persons, firms or corporations who need to know such Confidential Information during the course and within the scope of Executive’s
employment. Executive will not use any Confidential Information for any purpose or for Executive’s personal benefit other than in the course and within the scope of Executive’s employment. Executive agrees to sign and abide by

  
 - 4 - 

 
the terms and conditions of Company’s Confidential Information and Intellectual Property Protection Agreement, a copy of which is attached hereto as Schedule B and incorporated as
though fully set forth herein. 
 8. TERMINATION. This Agreement may be terminated by either party with or without Cause under the
following conditions: 
 (a) With Cause Termination. Executive may be terminated from employment with “Cause.”
“Cause” shall mean (i) the commission of a crime involving moral turpitude, theft, fraud or deceit; (ii) conduct which brings Company or any Affiliate into public disgrace or disrepute and that is demonstrably and materially
injurious to the business interest of Company or any Affiliate; (iii) substantial or continued unwillingness to perform duties as reasonably directed by Executive’s supervisors or Company’s Board of Directors; (iv) gross
negligence or deliberate misconduct; or (v) any material breach of Paragraphs 6 or 7 of this Agreement, or Executive’s Confidential Information and Intellectual Property Protection Agreement. In the event that Executive is terminated with
Cause, Company may immediately cease payment of any further wages, benefits or other compensation hereunder other than salary and benefits (excluding options) earned through the date of termination. Executive acknowledges that Executive has
continuing obligations under this Agreement including, but not limited to Paragraphs 6 and 7, in the event that Executive is terminated with Cause. 

(b) Without Cause Termination; Resignation. In the event that Executive’s employment is terminated by Company without Cause or
Executive resigns for Good Reason or at the direction of Company’s or Parent’s Board of Directors, Executive will be entitled to the following: 

(1) Twelve (12) months of Executive’s last monthly base salary, as set forth in Schedule A, less appropriate
deductions, divided into equal installments and paid on Company’s regular payroll dates over a period of twelve (12) months commencing with the first regular payroll date occurring on or after the sixtieth (60th) day following Executive’s termination date, together with a catch-up payment consisting of the installments that otherwise would have been paid on the regular payroll dates occurring
between the termination date and such initial payment date, and the remaining installments paid on succeeding regular payroll dates during such twelve (12)-month period until paid in full (“Severance Pay”). 

Executive shall not be eligible to participate in Company’s generally applicable severance policy (“Severance
Policy”), except as provided in Paragraph 8(b)(2) below. Severance Pay shall be payable under this Agreement and will be treated as paid in satisfaction of the Severance Policy as in effect from time to time to the extent of Executive’s
entitlement to payments under the Severance Policy. 
 (2) Executive’s annual performance-based cash bonus target, as
set forth in Schedule A, less appropriate deductions, payable on the sixtieth (60th) day following Executive’s termination of employment. 

  
 - 5 - 

 (3) Continued coverage under Company’s employee benefit plans (other than
401(k) or pension benefit coverage) after termination of employment for Executive and his eligible dependents, as and when provided under the Severance Policy, and subject to the payment of applicable premiums or other costs, all in accordance with
the terms of the Severance Policy and the applicable benefit plans (including, without limitation, cessation of such benefits due to receiving similar benefit coverage from a new employer) with such modifications as are necessary to comply with the
Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”). 
 (4) For a period of twelve (12) months
following Executive’s termination date, continued vesting in unvested stock options outstanding as of such termination date and granted under Company’s Stock Incentive Plan, or any successor thereto (the “Options”). 

(5) The exercise period for a vested Option, including those which vest pursuant to Paragraph 8(b)(4) above, will be extended
for a period of twelve (12) months after the otherwise applicable expiration date, but not later than the earlier of (i) the original expiration date of such Option; or (ii) ten (10) years from the date of grant. 

Executive further acknowledges that Company’s obligations under this Paragraph 8(b), are contingent upon and subject to Executive’s
signing (and not revoking) an agreement and release of all claims against Company in a form similar to the one attached hereto as Schedule C (or such other form acceptable to Company), and such release becoming effective in accordance with
its terms prior to the sixtieth (60th) day following Executive’s termination date. 

(c) Without Cause or Good Reason Termination following Change of Control. In the event that upon or within one (1) year following
a Change of Control, either Executive voluntarily terminates his employment with Company for Good Reason or Company terminates Executive’s employment with Company without Cause, Executive will be entitled to the following in lieu of the
payments and benefits to which Executive would otherwise be entitled upon such termination in accordance with Paragraph 8(b): 

(1) A lump sum payment, less appropriate deductions, equal to two (2) times the sum of (i) Executive’s average
annual base salary for the last three (3) years (including the year of termination); and (ii) Executive’s average annual performance-based cash bonus received for the prior three (3) years (not including the year of termination),
such payment to be made on the sixtieth (60th) day following Executive’s termination date. 

(2) Payment by Company of the premiums, less appropriate withholding, required to continue Executive’s and his eligible
dependents’ group health care (medical, dental, and vision) coverage under the applicable provisions of COBRA, provided that Executive timely elects to continue such coverage under COBRA, for a period ending on the first to occur of
(i) the date twenty-four (24) months following Executive’s termination of employment; and (ii) the date 

  
 - 6 - 

 
Executive becomes eligible for health care coverage through another employer, provided that the amount of the premiums payable under this Paragraph is equal to the excess of Executive’s cost
for COBRA coverage over the cost Executive would have paid for group health plan coverage as an active employee of Company. 

(3) Acceleration in full, effective as of Executive’s final day of employment, of the vesting and/or exercisability of all
then-outstanding equity awards held by Executive. 
 (4) The exercise period for a vested Option, including those which vest
pursuant to Paragraph 8(c)(3) above, will be extended for a period of twelve (12) months after the otherwise applicable expiration date, but not later than the earlier of (i) the original expiration date of such Option; or (ii) ten
(10) years from the date of grant. 
 (5) Reimbursement for outplacement services (not exceeding Twenty-Five Thousand
Dollars ($25,000)) in accordance with Company’s standard policies concerning reimbursement. 
 Executive further acknowledges that
Company’s obligations under this Paragraph 8(c), are contingent upon and subject to Executive’s signing (and not revoking) an agreement and release of all claims against Company in a form similar to the one attached hereto as Schedule
C (or such other form acceptable to Company), and such release becoming effective in accordance with its terms prior to the sixtieth (60th) day following Executive’s termination
date. 
 (d) Section 280G. Notwithstanding anything herein to the contrary, if any payment or benefit hereunder or otherwise
payable to Executive constitutes a “parachute payment” (as defined in Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended (“Code”)), and the net after-tax amount of any such parachute payment is less than the
net after-tax amount if the aggregate payments and benefits to be made to Executive were three times Executive’s “base amount” (as defined in Code Section 280G(b)(3)), less One Dollar ($1.00), then the aggregate of the amounts
constituting the parachute payments shall be reduced to an amount equal to three (3) times Executive’s base amount, less One Dollar ($1.00). If a reduction in severance and other benefits constituting parachute payments is necessary so
that benefits are delivered to a lesser extent, reduction will occur in the following order: reduction of cash payments; then reduction of employee benefits. 

The determinations to be made with respect to this Paragraph shall be made by Company’s independent accountants or such other person or
entity to which the parties mutually agree, which shall be paid by Company for the services to be provided hereunder. For purposes of making the calculations required by this Paragraph, the accountants may make reasonable, good faith interpretations
concerning the application of Code Sections 280G and 4999 and make reasonable assumptions regarding Executive’s marginal tax rate in effect for such parachute payments, including the effect of the deductibility of state and local taxes on such
marginal tax rate. Executive and Company shall furnish to accountants such information and documents as the accountants may reasonably request in order to make a determination under this Paragraph.

 9. TERM. Executive’s employment shall continue from year to year or until such
employment is terminated in accordance with the provisions of Paragraph 8. Executive acknowledges and agrees that nothing herein guarantees Executive continued employment by Company for any specified or intended term, and that his employment and
this Agreement may be terminated by Company at any time. 
 10. EQUITABLE RELIEF; FEES AND EXPENSES. Executive stipulates and agrees
that any breach of this Agreement by Executive will result in immediate and irreparable harm to Company and its Affiliates, the amount of which will be extremely difficult to ascertain, and that Company and its Affiliates could not be reasonably or
adequately compensated by damages in an action at law. For these reasons, Company and its Affiliates shall have the right to obtain such preliminary, temporary or permanent injunctions or restraining orders or decrees as may be necessary to protect
Company or any Affiliate against, or on account of, any breach by Executive of the provisions of this Agreement without the need to post bond. Such right to equitable relief is in addition to all other legal remedies Company or any Affiliate may
have to protect its rights. The prevailing party in any such action shall be responsible for reimbursing the non-prevailing party for all costs associated with obtaining the relief, including reasonable attorneys’ fees, and expenses and costs
of suit. Executive further covenants and agrees that any order of court or judgment obtained by Company or an Affiliate which enforces Company’s or Affiliate’s rights under this Agreement may be transferred, without objection or opposition
by Executive, to any court of law or other appropriate law enforcement body located in any other state in the United States or any other country in the world where Company or such Affiliate does business, and that said court or body shall give full
force and effect to said order and or judgment. 
 11. EMPLOYMENT DISPUTE SETTLEMENT PROCEDURE-WAIVER OF RIGHTS. In consideration of
Company employing Executive and the wages and benefits provided under this Agreement, Executive and Company each agree that, in the event either party (or its representatives, successors or assigns) brings an action in a court of competent
jurisdiction relating to Executive’s recruitment, employment with, or termination of employment from Company, the plaintiff in such action agrees to waive his, her or its right to a trial by jury, and further agrees that no demand, request or
motion will be made for trial by jury. 
 In consideration of Company employing Executive, and the wages and benefits provided under this
Agreement, Executive further agrees that, in the event that Executive seeks relief in a court of competent jurisdiction for a dispute covered by this Agreement, Company may, at any time within sixty (60) days of the service of Executive’s
complaint upon Company, at its option, require all or part of the dispute to be arbitrated by one arbitrator in accordance with the rules of the American Arbitration Association. Executive agrees that the option to arbitrate any dispute is governed
by the Federal Arbitration Act, and is fully enforceable. Executive understands and agrees that, if Company exercises its option, any dispute arbitrated will be heard solely by the arbitrator, and not by a court. The parties agree that the
prevailing party shall be entitled to have all of their legal fees paid by the non-prevailing party. This pre-dispute resolution agreement will cover all matters directly or indirectly related to Executive’s recruitment, employment or
termination of employment by Company; including, but not limited 

  
 - 8 - 

 
to, claims involving laws against any form of discrimination whether brought under federal and/or state law, and/or claims involving co-employees, but excluding Worker’s Compensation Claims.

 THE RIGHT TO A TRIAL, AND TO A TRIAL BY JURY, IS OF VALUE. YOU MAY WISH TO CONSULT AN ATTORNEY PRIOR TO SIGNING THIS AGREEMENT. IF
SO, TAKE A COPY OF THIS AGREEMENT WITH YOU. HOWEVER, YOU WILL NOT BE OFFERED EMPLOYMENT UNDER THIS AGREEMENT UNTIL THIS AGREEMENT IS SIGNED AND RETURNED BY YOU. 

12. AMENDMENTS. No supplement, modification, amendment or waiver of the terms of this Agreement shall be binding on the parties hereto
unless executed in writing by the party to be bound thereby. No waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provisions hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided. Any failure to insist upon strict compliance with any of the terms and conditions of this Agreement shall not be deemed a waiver of any such terms or conditions. 

13. ACKNOWLEDGMENTS OF EXECUTIVE. Executive hereby acknowledges and agrees that: (a) this Agreement is necessary for the
protection of the legitimate business interests of Company and its Affiliates; (b) the restrictions contained in this Agreement may be enforced in a court of law whether or not Executive is terminated with or without cause or for performance
related reasons; (c) Executive has no intention of competing with Company and its Affiliates within the limitations set forth above; (d) Executive has received adequate and valuable consideration for entering into this Agreement;
(e) Executive’s covenants shall be construed as independent of any other provision in this Agreement and the existence of any claim or cause of action Executive may have against Company or any Affiliate, whether predicated on this
Agreement or not, shall not constitute a defense to the enforcement by Company or an Affiliate of these covenants; and (f) the execution and delivery of this Agreement is a mandatory condition precedent to Executive’s receipt of the
consideration provided herein. 
 14. FULL UNDERSTANDING. Executive acknowledges that Executive has been afforded the opportunity to
seek legal counsel, that Executive has carefully read and fully understands all of the provisions of this Agreement and that Executive, in consideration for the compensation set forth herein, is voluntarily entering into this Agreement. 

15. ENTIRE AGREEMENT. This Agreement supersedes all prior agreements, written or oral, between Company or Affiliates and Executive
concerning the subject matter hereof. 
 16. SEVERABILITY. Whenever possible, each provision of this Agreement shall be interpreted
in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality
or unenforceability shall not affect any other provision or any other jurisdiction, but this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained
herein. The restrictive covenants stated herein may be read as if separate and apart from this Agreement and shall survive the termination of Executive’s employment with Company for any reason. 

  
 - 9 - 

 17. OTHER AGREEMENTS. Executive represents and warrants that Executive is not a party to
or otherwise subject to or bound by the terms of any contract, agreements or understandings that would affect Executive’s right or abilities to perform under this Agreement. Executive specifically represents that Executive will not use any
confidential information obtained from Executive’s prior employer(s) in the performance of Executive’s duties herein and is not subject to any other restrictive covenants or non-competition agreements. 

18. CHOICE OF LAW, JURISDICTION AND VENUE. The parties agree that this Agreement shall be deemed to have been made and entered into in
Allegheny County, Pennsylvania and that the law of the Commonwealth of Pennsylvania shall govern this Agreement, without regard to conflict of laws principles. Jurisdiction and venue is exclusively limited in any proceeding by Company or an
Affiliate or Executive to enforce their rights hereunder to any court or arbitrator geographically located in Allegheny County, Pennsylvania. Executive hereby waives any objections to the jurisdiction and venue of the courts in or for Allegheny
County, Pennsylvania, including any objection to personal jurisdiction, venue, and/or forum non-conveniens, in any proceeding by Company or any Affiliate to enforce its rights hereunder filed in or for Allegheny County, Pennsylvania. Executive
agrees not to object to any petition filed by Company or an Affiliate to remove an action filed by Executive from a forum or court not located in Allegheny County, Pennsylvania. 

19. SUCCESSORS IN INTEREST. This Agreement shall be binding upon and shall inure to the benefit of the successors, assigns, heirs and
legal representatives of the parties hereto. Parent and Company shall each require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of its business and/or assets to assume
expressly and agree to perform this Agreement in the same manner and to the same extent that Parent or Company, as the case may be, would be required to perform it if no such succession had taken place, and Executive agrees to be obligated by this
Agreement to any successor, assign or surviving entity. As used in this Paragraph, “Parent” shall mean Parent as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this
Agreement by operation of law, or otherwise and “Company” shall mean Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or
otherwise. Any successor to Company is an intended third party beneficiary of this Agreement. Executive may not assign this Agreement otherwise than by will or the laws of decent and distribution.

21. SECTION 409A. 
 (a)
Notwithstanding anything herein to the contrary, this Agreement is intended to be interpreted and applied so that the payment of the benefits set forth herein either shall either be exempt from the requirements of Code Section 409A
(“Section 409A”) or shall comply with the requirements of such provision. Notwithstanding any provision of this Agreement to the contrary, if Executive is a “specified employee” within the meaning of Section 409A, any
payments or arrangements due upon a termination of Executive’s employment, if any, under any arrangement that constitute a “nonqualified deferral of compensation” within the meaning of Section 409A and which do not otherwise
qualify under the exemptions under Treas. Regs. Section 1.409A-1 (including without limitation, the short-term deferral exemption or the permitted payments under Treas. Regs. Section 1.409A-1(b)(9)(iii)(A)), shall be delayed and paid or
provided on the earlier of (i) the date which is six months after Executive’s “separation from service” (as such term is defined in Section 409A and the regulations and other published guidance thereunder) for any reason
other than death; and (ii) the date of Executive’s death. 
 (b) After Executive’s termination, Executive shall have no
duties or responsibilities that are inconsistent with having a “separation from service” within the meaning of Section 409A as of the date of his termination and, notwithstanding anything in the Agreement to the contrary,
distributions upon termination of employment of nonqualified deferred compensation may only be made upon a “separation from service” as determined under Section 409A and such date shall be the date of Executive’s termination for
purposes of this Agreement. Each payment under this Agreement or otherwise shall be treated as a separate payment for purposes of Section 409A. In no event may Executive, directly or indirectly, designate the calendar year of any payment to be
made under this Agreement which constitutes a “nonqualified deferral of compensation” within the meaning of Section 409A and to the extent an amount is payable within a time period, the time during which such amount is paid shall be
in the discretion of Company.

23. HEADINGS. The headings used in this Agreement are for convenience only and are not to be considered in construing or interpreting
this Agreement. 
 24. DRAFTER PROVISION. The parties agree that they have both had the opportunity to review and negotiate this
Agreement, and that any inconsistency or dispute related to the interpretation of any of the provisions of this Agreement shall not be construed against either party.

 Schedule A (3) 

This Schedule A (3) dated March 20, 2014, is issued pursuant to the Amended and Restated Executive Employment Agreement by and among Company,
Parent and Executive, dated March 20, 2014 (the “Agreement”), and shall be incorporated therein and governed by the terms and conditions of such Agreement. This Schedule A (3) is effective April 1, 2014, and is
intended to replace any previously issued Schedule A. 
 1. Position: Chief Executive Officer and President of Parent and Company. Executive
shall report in such capacity to the Parent’s Board of Directors. Executive shall also be an executive officer of Company and report to Company’s Boards of Directors. 

2. Base Salary: $370,000 per year. 
 3. Bonus:
Executive will be entitled to an annual performance-based cash bonus of $210,000, for the achievement of certain financial and operational targets. These targets, and the bonus dollars tied to such targets, will be determined and communicated to you
by the Compensation Committee of Parent’s Board of Directors on an annual basis. For the 2014 calendar year, your bonus will be based on the following performance measures: 

 

	 	a.	Consolidated Revenue; 

  

	 	b.	Consolidated Earnings Per Share; and 

  

	 	c.	Subjective performance. 

 The target amount for each measure for the 2014 calendar year is set forth on
Appendix 1 to this schedule. Should Company fail to achieve the target amount for the above performance measures, Executive’s annual performance-based bonus, if any, shall be based upon Company’s evaluation of the percentage
of the target amount achieved during the year. Conversely, should Company’s performance exceed the target amount for the above performance measures, Executive’s annual performance-based bonus may exceed the bonus amount stated above, based
upon Company’s evaluation of the percentage of the over-achievement of such target amount(s). All bonuses will be paid by February 15, 2015, following the completion of Company’s year-end audit. If Executive leaves Company
voluntarily, or is terminated with Cause, before December 31, 2014, Executive will not be eligible for a bonus. If Executive is terminated by Company during 2014 without Cause, Executive’s bonus calculation will be based on Company’s
annual results (calculated as though Executive were still an employee) and a prorated bonus will be paid considering the days in 2014 in which Executive was employed by Company divided by 365. 

4. Benefits: Executive is eligible for standard company benefits in the same manner as other executives of Company and Parent. 

5. Expenses: Company will reimburse all properly documented expenses reasonably related to Executive’s performance of Executive’s duties
hereunder. 

  
 - 14 - 

 6. Stock Options: Executive shall be eligible to receive non-qualified stock options pursuant to
Company’s Stock Incentive Plan.
