undertakings of the parties hereto, the Company and Executive agree as follows:

continue until the second anniversary of such date (the “Initial Term”), which shall automatically renew on the second and each following anniversary of the Effective Date for successive one (1) year terms (each, a
“Successive Term”) (the Initial Term, together with all Successive Terms, if any, are collectively referred to herein as the “Employment Period”), unless either party provides the other party with written notice at
least six (6) months prior to the expiration of the Initial Term, or any Successive Term, of its or his intent not to renew the Initial Term, or any Successive Term, respectively. The Employment Period may be terminated earlier pursuant to the

Agreement, commencing on the Effective Date and thereafter during the Employment Period, Executive shall hold the position of Executive Vice President and Chief Strategy Officer and shall report to the Chief Executive Officer. Executive shall
perform such duties and responsibilities as are consistent with Executive’s position and as may be reasonably assigned to Executive by the Chief Executive Officer from time to time. Executive shall devote Executive’s full business time,

limits, budgets and business plans set by the Company, and shall adhere to all rules and regulations in effect from time to time relating to the conduct of executives of the Company. 

1.3 Other Activities. Notwithstanding Section 1.2, Executive shall be permitted to devote a reasonable amount

occurring in 2016, subject to and in accordance with the terms of the Annual Bonus Plan, Executive shall be provided a target bonus equal to 80% of his Base Salary (the “2016 Bonus”). For the portion of the Employment Period
occurring in 2015 Executive shall be entitled to a guaranteed pro rata bonus under the Annual Bonus Plan which is equal to twenty four thousand three hundred thirty three dollars ($24,333) (the “2015 Bonus”).

connection with his commencing employment with the Company, on the Effective Date Executive is being awarded under the Long Term Incentive Plan a time vesting restricted stock grant (the “Initial Grant”) for six hundred thousand
dollars ($600,000) of the Company common stock, valued as of market closing on the date of grant, and vesting in equal semi-annual installments over 4 years from the Effective Date. The terms and conditions of the Initial Grant shall be governed by

eligibility requirements of such plans). The Company reserves the right to modify, suspend or discontinue any and all of its employee benefit plans, practices, policies and programs at any time without recourse by Executive, so long as the Company

 ARTICLE III 

TERMINATION OF EMPLOYMENT 

3.1 Voluntary Resignation. Executive may terminate his employment for any reason by giving the Company 90 days prior written
notice of a voluntary resignation date (“Resignation Date”). Upon receiving Executive’s notice of intent to resign, the Company may require that Executive cease performing services for the Company at any time before the
Resignation Date, so long as the Company continues Executive’s Base Salary, service for purposes of the Annual Bonus Plan and Long-Term Incentive Plan, and employee benefits under Section 2.4 through the Resignation Date. Except as
otherwise provided under law or the terms of the Annual Bonus Plan, the Long-Term Incentive Plan, or any other employee benefit plan in which Executive participates, Executive shall not be entitled to receive any compensation or benefits from the
Company after the Resignation Date. For the avoidance of doubt, any annual incentive bonus that has not been paid as of the Resignation Date will not be payable and is forfeited. 

3.2 Termination By Company for Cause. The Company may terminate Executive’s employment for Cause (as defined below) by
giving written notice to Executive designating an immediate or future termination date. Such notice shall indicate the specific provisions of this Agreement relied upon as the basis of such termination. In the event of a termination for Cause, the
Company shall pay Executive his Base Salary and provide employee benefits under Section 2.4 through the termination date. Except as otherwise provided under law or the terms of the Annual Bonus Plan, the Long-Term Incentive Plan, or any
other employee benefit plan in which Executive participates, Executive shall not be entitled to receive any compensation or benefits from the Company after the termination date. 

For purposes of this Agreement, “Cause” means: 

(i) Executive materially breaches Executive’s obligations under this Agreement, the Company’s Code of Conduct and
Ethics (or any successor thereto) or an established policy of the Company; 
 (ii) Executive engages in conduct prohibited by
law (other than minor violations), commits an act of dishonesty, fraud, or serious or willful misconduct in connection with his job duties, or engages in unethical or immoral conduct that, in the reasonable judgment of the Committee, could injure
the integrity, character or reputation of Company; 

  
 4 








 (iii) Executive fails or refuses to perform, or habitually neglects,
Executive’s duties and responsibilities hereunder (other than on account of Disability (as defined below), and continues such failure, refusal or neglect after having been given written notice by the Company that specifies what duties Executive
failed to perform and an opportunity to cure of 30 days; 
 (iv) Use or disclosure by Executive of confidential information
or trade secrets other than in the furtherance of the Company’s (or its subsidiaries’) business interests, or other violation of a fiduciary duty to the Company (including, without limitation, entering into any transaction or contractual
relationship causing diversion of business opportunity from the Company (other than with the prior written consent of the Board)); or 

(v) Executive fails to reasonably cooperate with any audit or investigation involving the Company or its business practices
after having been given written notice by the Company that specifies Executive’s failure to cooperate and an opportunity to cure of 10 days. 

3.3 Termination By Company Without Cause or Termination by Executive for Good Reason. The Company may terminate Executive’s
employment without Cause at any time during the Employment Period by giving written notice to Executive designating an immediate or future termination date. 

Executive may resign from employment during the Employment Period due to: 

(i) a failure to provide the compensation and benefits required by this Agreement, including a reduction in Executive’s
Base Salary below the Base Salary in effect during the immediately preceding year, unless such reduction is commensurate with and part of a general salary reduction program applicable to all senior executives of the Company or agreed to in writing
by Executive; 
 (ii) a failure to appoint or elect Executive as Executive Vice President and Chief Strategy Officer of the
Company, in accordance with Section 1.2 hereof; 
 (iii) any material diminution of Executive’s authority,
duties or responsibilities; or 
 (iv) the Company requiring Executive to be based at any office or location other than the
office provided for in Section 1.4 hereof; 
 (each of which shall constitute a “Company Breach” or “Good
Reason”) and such resignation shall be treated as a termination by Executive for Good Reason; provided that, (a) Executive’s voluntary resignation occurs within 90 days following the initial occurrence of a Company Breach,
(b) Executive provided written notice describing such Company Breach in reasonable 

  
 5 








 
detail to the Committee within 30 days of the initial occurrence of such Company Breach, and (c) the Company failed to cure such Company Breach within 30 days of receipt of such written
notice from Executive; and provided, further, that in the case of subsections (ii) and (iii), an act or omission shall not constitute a Company Breach if Executive has incurred a Disability (as defined below). 

The election by Executive to not renew the Initial Term or any Successive Terms pursuant to Section 1.1 shall not be a termination
for Good Reason and shall not entitle Executive to Severance Pay. However, the election by the Company to not renew the Initial Term or any Successive Terms pursuant to Section 1.1 shall be deemed to be a termination without Cause
effective as of the termination of the Initial Term or Successive Term as applicable, and shall entitle Executive to Severance Pay as hereinafter provided. 

In the event of a termination by the Company without Cause or a termination by Executive for Good Reason, the Company shall pay Executive his
Base Salary and provide employee benefits under Section 2.4 through the termination date. In addition, subject to the requirements set forth in Section 3.7, Section 3.8, and Section 3.9, the Company
will provide the following compensation and benefits to Executive (collectively, the “Severance Pay”): 

(A) an amount equal to six (6) months of Executive’s then current Base Salary, plus an amount equal to 50% of his
target bonus under the Annual Bonus Plan for the current year in which Executive’s employment terminates, or if such target has not been established for such current year, then the most recently established target bonus under the Annual Bonus
Plan, each less applicable withholdings, payable in equal installments on each regularly scheduled payroll pay date during the six (6) month period that begins on the first day immediately after the Release Effective Date (as defined in
Section 3.7); and 
 (B) Awards, if any, under the Long Term Incentive Plan shall be paid in accordance with the
terms and conditions of the Long-Term Incentive Plan and the applicable awards. 
 Except as otherwise provided under law, or the terms of
the Annual Bonus Plan, the Long-Term Incentive Plan, or any other employee benefit plan in which Executive participates, Executive shall not be entitled to receive any additional compensation or benefits from the Company after the termination date.

 3.4 Death. The Employment Period shall terminate automatically upon Executive’s death. In the event of
Executive’s death during the Employment Period, the Company shall pay Executive’s Base Salary and provide employee benefits under Section 2.4 through the termination date. Except as otherwise provided under law or the terms of
the Annual Bonus Plan, the Long-Term Incentive Plan, or any other employee benefit plan in which Executive participates, no other compensation or benefits from the Company shall be payable after the termination date. 

  
 6 








 3.5 Disability. “Disability” means Executive being unable to
perform his duties to the Company as Executive Vice President and Chief Strategy Officer as provided in this Agreement for a period of at least 180 continuous days as a result of a mental or physical condition. The Company may terminate
Executive’s employment for Disability during the Employment Period by giving written notice to Executive designating a termination date that is at least 30 days after the date of the notice of termination, provided that Executive does
not return to work on a substantially full-time basis within 30 days after notice of termination on account of Disability is provided to Executive. A return to work of less than 30 continuous days on a substantially
full-time basis shall not interrupt a continuous period of Disability. In the event of termination of the Employment Period on account of Executive’s Disability, the Company shall pay Executive’s
Base Salary and provide employee benefits under Section 2.4 through the termination date. Except as otherwise provided under law or the terms of the Annual Bonus Plan, the Long-Term Incentive Plan, or any other employee benefit plan in
which Executive participates, no other compensation or benefits from the Company shall be payable after the termination date. 
 3.6
Change in Control. “Change in Control” has the meaning assigned to such term in the Long Term Incentive Plan as in effect from time to time. Notwithstanding anything in this Agreement to contrary, a Change in Control will
have occurred only if such change in ownership constitutes a change in control under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations and other guidance in effect thereunder
(“Section 409A”). 
 If contemporaneous with or within eighteen (18) months after a Change in Control that occurred
during the Employment Period (a) the Company terminates Executive’s employment without Cause or (b) Executive terminates his employment for Good Reason, then, provided Executive complies with the requirements set forth in
Section 3.7, Section 3.8, and Section 3.9, Executive will be eligible to receive Severance Pay described in Section 3.3 (collectively, the “Change in Control Payments”). 

The Change in Control Payment which is a cash payment (and not securities) will be made in a lump sum cash payment as soon as practicable, but
in no event more than ten (10) days after Release Effective Date. Except as otherwise provided under law or the terms of any other employee benefit plan in which Executive participates, Executive shall not be entitled to receive any additional
compensation or benefits from the Company after the termination date. 
 3.7 Execution of Separation Agreement. As a condition
to receiving Severance Pay or Change in Control Payments, Executive must execute and return to the Company, and not revoke any part of, a general release and waiver of claims against the Company and its officers, directors, stockholders, employees
and affiliates with respect to Executive’s employment (including, without limitation, a release of claims under the Age Discrimination in Employment Act (the “ADEA Release”)), and other customary terms, in a form and substance
reasonably acceptable to the Company (the “Release”). Executive must deliver the executed Release within the minimum time period required by law or, if none, within twenty-one (21) days after Executive receives the Release from
the Company, which shall not be more than fifteen (15) days after Executive’s termination of Employment. The Release will become effective on the date the revocation period of the ADEA Release expires without Executive revoking the ADEA


  
 7 








 
Release (the “Release Effective Date”). Any obligation of the Company to provide the Severance Pay shall cease: (i) if Executive materially breached or breaches his
contractual obligations to the Company, including those set forth in Article IV or Article V herein, or in the Release or (ii) if, after Executive’s termination, the Company discovers facts and circumstances that would have
justified a termination for Cause during the Employment Period. 
 3.8 Timing of Payments; Section 409A. 

(a) Notwithstanding any other provision of this Agreement, in the event of a payment to be made, or a benefit to be provided,
pursuant to this Agreement based upon Executive’s “separation from service” (as defined below) for a reason other than death at a time when Executive is a Specified Employee (as defined below) and such payment or provision of such
benefit is not exempt or otherwise permitted under Section 409A without the imposition of any Section 409A Penalty (as defined below), such payment shall not be made, and such benefit shall not be provided, before the earlier of the date
which is the first day of the seventh month after Executive’s separation from service or 30 days after Executive’s death. All payments or benefits delayed pursuant to this Section 3.8 shall be aggregated into one lump sum
payment to be made as of the Company’s first business day following the first day of the seventh month after Executive’s separation from service (or if earlier, as of 30 days after Executive’s death). 

(b) For purposes of this Agreement: 

(i) “Separation from service” has the meaning provided under Code Section 409A and Treas. Reg.
1.409A-1(h); 
 (ii) “Specified Employee” has the meaning given that term in Code Section 409A and
Treas. Reg. 1.409A-1(c)(i) as determined in accordance with the Company’s policy for determining Specified Employees; 

(iii) “Section 409A Penalty” means any increase in tax or any other penalty pursuant to Section 409A; and

 (iv) All payments of “deferred compensation,” as defined in Code Section 409A, due to Executive’s
“termination of employment” shall be payable upon Executive’s separation from service. 
 (c) This Agreement
is intended not to result in the imposition of any Section 409A Penalty and shall be administered, interpreted and construed in a manner consistent with such intent. 

(d) Executive and the Company agree to cooperate to amend this Agreement from time to time as appropriate to avoid the
imposition of any Section 409A Penalty. 
 (e) In no event shall the Company be required to provide a tax gross-up
payment to Executive with respect to any Section 409A Penalty. 
 (f) Notwithstanding any provision of this Agreement to
the contrary, this Agreement is intended to be exempt from or, in the alternative, comply with Section 409A and the interpretive guidance in effect thereunder, including the exceptions for short-term deferrals, separation pay arrangements,
reimbursements, and in-kind distributions. The Agreement shall be construed and interpreted in accordance with such intent. 

  
 8 








 3.9 Excess Parachute Payments; No Excise Tax Gross-Up. Notwithstanding any
provision of this Agreement to the contrary, if it is determined by the Company’s independent auditors that any amount or benefit to be paid or provided under this Agreement or otherwise, whether or not in connection with a Change in Control,
would be an “Excess Parachute Payment” within the meaning of Code Section 280G but for the application of this sentence, then the payments and benefits to be paid or provided under this Agreement will be reduced to the minimum
extent necessary (but in no event to less than zero) so that no portion of any such payment or benefit, as so reduced, constitutes an Excess Parachute Payment; provided, however, that the foregoing reduction will be made only if and to
the extent that such reduction would result in an increase in the aggregate payment and benefits to be provided, determined on an after-tax basis (taking into account the excise tax imposed pursuant to Code Section 4999, any tax imposed by any
comparable provision of state law, and any applicable federal, state and local income and employment taxes). 
 The fact that
Executive’s right to payments or benefits may be reduced by reason of the limitations contained in this Section 3.9 will not of itself limit or otherwise affect any other rights of Executive other than pursuant to this Agreement. In
the event that any payment or benefit intended to be provided under this Agreement or otherwise is required to be reduced pursuant to this Section 3.9, the Company will effect such reduction by reducing the lump sum cash payment related
to Base Salary (a “Reduction”). In the event that, after such Reduction any payment or benefit intended to be provided under this Agreement or otherwise is still required to be reduced pursuant to this Section 3.9, the
Company will effect such reduction by reducing other consideration due to Executive. 
 3.10 Removal from any Boards and
Positions. If Executive’s employment is terminated for any reason under this Agreement, this Agreement will constitute his automatic resignation from (i) if a member, the board of directors of any subsidiary of the Company or any
other board to which he has been appointed or nominated by or on behalf of the Company, (ii) any position with the Company or any subsidiary of the Company, including, but not limited to, as an officer of the Company or any of its subsidiaries,
and (iii) any fiduciary positions with respect to the Company’s benefit plans. 
 ARTICLE IV

Company and its subsidiaries and any other entity related to the Company (each, a “VASCO Entity”) that he obtained during the course of his employment by the Company is the property of the Company or such other VASCO Entity.
Executive will never, directly or indirectly, disclose, publish or use any Confidential Information 

  
 9 








 
of which Executive has become aware, whether or not such information was developed by him. All duties and obligations set forth in this Agreement regarding Confidential Information shall be in
addition to those which exist under the Illinois Trade Secrets Act and at common law.

recapitalizations, or new ventures; and 
 (xii) nonpublic information that was acquired by Executive concerning the
requirements and specifications of the Company’s or any other VASCO Entity’s agents, distributors, vendors, contractors, licensors, licensees, customers, or potential customers. 

Notwithstanding anything to the contrary, Confidential Information does not include any information that: (a) is publicly disclosed by
law or pursuant to, and to the extent required by, an order of a court of competent jurisdiction or governmental agency; (b) becomes publicly available through no fault of Executive; or (c) has been published in a form generally available
to the public before Executive proposes to disclose, publish, or use such information. 

  
 10 








 4.2 Noncompetition. During the Employment Period and for the 12-month period
following the termination of the Employment Period for any reason (the “Restricted Period”), Executive will not, on behalf of himself or any other entity, have an ownership interest in or become employed or engaged by, or otherwise
participate in or render services to, any business or enterprise (including, without limitation, any division, group or franchise of a larger organization) within the Geographical Area (as defined below) that engages in any data security business or
any other business engaged in by the Company; provided, however, that the this restriction shall not prohibit Executive from passive beneficial ownership of less than two percent of any class of securities of a publicly-held
corporation whose stock is traded on a U.S. national securities exchange or traded in the over-the-counter market. For the purpose of this provision, “Geographical Area” means North America, Central America, South America, the
Caribbean, Europe, the Middle East, Africa, India, the Australian continent and Asia. 
 4.3 Non-Solicitation. During the
Restricted Period, Executive shall not (other than in furtherance of Executive’s legitimate job duties on behalf of Company), directly or indirectly, on Executive’s own behalf or for any other person or entity: (i) solicit for
employment, hire or engage, or attempt to solicit for employment, hire or engage, any person who is or was employed by the Company within the six month period prior to the date of solicitation, hire or engagement, or (ii) otherwise interfere
with the relationship between any such person and the Company. 
 4.4 Non-Interference with Business Relationships. During the
Restricted Period, Executive shall not (other than in furtherance of Executive’s legitimate job duties on behalf of the Company), directly or indirectly, on Executive’s own behalf or for any other person or entity: (i) induce or
attempt to induce any customer, distributor, agent, licensor, licensee, contractor, vendor or other business relation that was doing business with any VASCO Entity during the one-year period prior to the inducement or attempted inducement to reduce
or cease doing business with the Company or any VASCO Entity, or otherwise interfere with the relationship between such person (or entity) and any VASCO Entity; (ii) induce or attempt to induce any prospective customer, distributor, agent,
licensor, licensee, contractor, vendor or other prospective business relation located in the Geographical Area with which any VASCO Entity has had communications during the six-month period prior to the inducement or attempted inducement regarding
doing business with the Company or any other VASCO Entity to not do business or to do reduced business with the Company or any other VASCO Entity, or otherwise interfere with the relationship between such person (or entity) and any VASCO Entity.

 4.5 Equitable Modification. If any court of competent jurisdiction shall deem any provision in this Article IV too
restrictive, the other provisions shall stand, and the court shall modify the unduly restrictive provision to the point of greatest restriction permissible by law. 

4.6 Remedies. Executive acknowledges that the agreements and covenants contained in this Article IV are essential to
protect the Company and its business and are a condition precedent to entering into this Agreement. Should Executive breach any covenants in this Article IV, then among other remedies, the duration of the covenant shall be extended by the
period of any such breach. Executive agrees that irreparable harm would result from Executive’s breach or threat to breach any provision of this Article IV, and that monetary damages alone would not provide adequate relief to the Company
for the harm incurred. Executive agrees that in addition to money damages, the Company shall be entitled to seek and obtain temporary, 

  
 11 








 
preliminary and permanent injunctive relief restraining Executive from committing or continuing any breach without being required to post a bond. Without limiting the foregoing, upon a breach by
Executive of any provision of this Article IV, any outstanding Severance Pay shall cease and be forfeited, and Executive shall immediately reimburse the Company for any Severance Pay previously paid.

records, policies, marketing information, design information, specifications and plans, data base information and lists, and any other property or information that Executive has or had relating to the Company (whether those materials are in paper or
computer-stored form), and including but not limited to any documents containing, summarizing, or describing any Confidential Information. 

5.2 Executive Assistance. During Executive’s employment with the Company and for a period of 3 years after the termination
of such employment, Executive shall, upon reasonable notice, furnish the Company with such information as may be in Executive’s possession or control, and cooperate with the Company in any reasonable manner that the Company may request,

to the contrary, any such reimbursement shall be administered so as to comply with Treasury Regulation Section 1.409A-3(i)(1)(iv).
