 (b) The Executive shall devote his full working time and creative energies to the performance of his duties hereunder and will at all

duties hereunder: (i) the Executive shall be permitted a reasonable amount of time to supervise his personal, passive investments; and (ii) the Executive shall be permitted a reasonable amount of time to participate (as board member,
officer or volunteer) in civic, political and charitable activities.

Executive’s principal place of employment shall be in Lanham, Maryland, subject to such travel as may be reasonably required by his employment pursuant to the terms hereof. 
 2. Term of Employment. 
 2.1 Term of Employment. Executive agrees that the initial term of this Agreement shall be for a period of three (3) years commencing on the date first written above (the “Effective Date”)
and will continue until the first anniversary of the Effective Date (as may be extended, the “Term”). At the end of the initial Term or at the end of any twelve (12) month renewal period (as described in Section 2.2
below), the Term of this Agreement may automatically extend as provided below in Section 2.2. Notwithstanding anything to the contrary contained herein, the Company may terminate Executive’s employment with or without Cause.

 2.2 Renewal Periods. If this Agreement has not been terminated earlier in
accordance with the provisions of this Agreement, at the end of the initial Term or any twelve (12) month renewal period, the Term shall be extended automatically for an additional twelve (12) month period unless either party provides
written notice of non-renewal to the other party at least one hundred twenty (120) days prior to the last day of the Term or any renewal period, as applicable. 
 3. Compensation. 
 3.1 Salary. As compensation for
all services to be rendered pursuant to this Agreement, the Company shall pay to the Executive during the Term a salary of $235,000 per annum (the “Base Salary”), which shall be pro-rated for calendar year 2007, less such deductions as
shall be required to be withheld by applicable laws and regulations or as otherwise authorized by the Executive. The Base Salary shall accrue from and after the Effective Date, and shall be payable during the Term, in arrears in equal periodic
installments and in accordance with the practices of the Company in effect from time to time for the payment of salaries to employees of the Company, but in any event not less frequently than monthly. The Executive’s Base Salary shall be
reviewed at least annually and may be increased (but not decreased) based upon the evaluation of the Executive’s performance and the compensation policies of the Company in effect at the time of each such review. 
 3.2 Additional Compensation. During the Term, Executive shall be entitled to
participate, in accordance with the terms thereof and in a manner substantially similar to other similarly situated executive officers, in any present or future bonus, profit sharing, stock option (whether incentive or non qualified) or other
employee compensation or incentive plan adopted by the Company. 
 3.3 Participation in Executive Officer
Benefit Plans; Vacation. The Executive shall be permitted during the Term, if and to the extent eligible, to participate in any group life, hospitalization or disability insurance plan, health program, 401(k) pension or similar benefit
plan of the Company which may be available to other executive officers of the Company generally on the same terms as such other executive officers. The Executive shall receive vacation in accordance with the vacation policy of the Company.

 3.4 Expenses. The Company shall pay or reimburse the Executive for all ordinary, necessary and
reasonable expenses (including, without limitation, travel, meetings, dues, subscriptions, fees, educational expenses, computer equipment, mobile telephones, professional insurance, and the like) actually incurred or paid by the Executive during the
Term in the performance of the Executive’s services under this Agreement, upon presentation of expense statements or vouchers or such other supporting information as may be required by the policies and procedures of the Company in effect from
time to time. 
  

 -2- 

 3.5 Withholding. The Company is authorized to withhold from the
amount of any Base Salary and any other things of value paid to or for the benefit of the Executive, all sums authorized by the Executive or required to be withheld by law, court decree, or executive order, including (but not limited to) such things
as income taxes, employment taxes, and employee contributions to fringe benefit plans sponsored by the Company. 
 4.
Termination. 
 4.1 General. The employment of the Executive hereunder shall
terminate as provided in Section 2, unless earlier terminated in accordance with the provisions of this Section 4. 
 4.2 Termination Upon Mutual Agreement. The Company and the Executive may, by mutual written agreement, terminate this Agreement and/or the employment of the Executive at any time.

 4.3 Death or Disability of Executive.  
 (a) The employment of the Executive hereunder shall terminate upon (i) the death of the Executive, and (ii) at the option of the
Company upon not less than thirty (30) days’ prior written notice to the Executive or his personal representative or guardian, if the Executive suffers a “Total Disability” (as defined in Section 4.3(b) below).

 (b) For purposes of this Agreement, “Total Disability” shall mean (i) if the Executive is subject to a legal
decree of incompetency (the date of such decree being deemed the date on which such disability occurred), or (ii) the written determination by a physician selected by the Company that, because of a medically determinable disease, injury or
other physical or mental disability, the Executive is unable substantially to perform each of the material duties of the Executive required hereby, and that such disability has lasted for the immediately preceding ninety (90) days and is, as of
the date of determination, reasonably expected to last an additional ninety (90) days or longer after the date of determination, in each case based upon medically available reliable information, and the provision of clear and convincing
evidence by the Company of the Executive’s inability substantially to perform each material duty hereunder in support of such determination by the physician. 
 (c) Any leave on account of illness or temporary disability which is short of “Total Disability” shall not constitute a breach
of this Agreement by the Executive and in no event shall any party be entitled to terminate this Agreement for “Cause” (as defined in Section 4.4 below) due to any such leave. All physicians selected hereunder shall be Board
certified in the specialty most closely related to the nature of the disability alleged to exist. 
 4.4 Termination
For Cause. The Company may, upon written notice to the Executive specifying in reasonable detail the reason therefore, terminate the employment of the Executive at any time for “Cause” (as defined below).
For purposes of this Agreement, “Cause” means (i) the material failure of the Executive to perform his duties under this Agreement, or to 

  

 -3- 

 
follow the Company’s policies and procedures applicable to executive officers of the Company in effect from time to time, after notice and a reasonable
opportunity to cure; (ii) willful malfeasance by the Executive in connection with the performance of his duties under this Agreement; (iii) the Executive being convicted of, or pleading guilty or nolo contendere to, or being indicted for a
felony or other crime involving theft, fraud or moral turpitude; (iv) fraud or embezzlement against the Company; (v) the failure of the Executive to obey in any material respects any proper written direction of the Chief Executive Officer
of the Company that is not inconsistent with this Agreement; (vi) or the material violation by the Executive of any of the provisions of Section 5 of this Agreement. 
 4.5 Payments Upon Termination. 
 (a) The Company may at any time during the Term terminate the Executive without Cause. In the event the Executive’s employment is
terminated by the Company without Cause during the Term, then the Company shall pay (on the same schedule used to pay Base Salary to the Executive during the Term) the Executive: 
 (1) the Base Salary to which the Executive would have been entitled pursuant to Section 3.1 of this Agreement had the
Executive remained in the employ of the Company for a period commencing upon the date of such termination and ending on the first anniversary of the date of termination (“Termination Coverage Period”); provided, however, that in the event
that during the Termination Coverage Period such period Executive receives compensation from a third party employer (“Third Party Employer Compensation”), then Executive shall promptly provide written evidence of such compensation and any
payments under this Section 4.5(a) shall be net of such Third Party Employer Compensation, and 
 (2) The
Executive’s COBRA Premiums for the Termination Coverage Period, or the portion thereof, that Executive or Executive’s dependents are eligible for such COBRA coverage. 
 (b) In the event the Executive’s employment is terminated (i) by the Company for Cause, or (ii) voluntarily by the
Executive, then the Company shall have no duty to make any payments or provide any benefits to the Executive pursuant to this Agreement other than payment of the amount of the Executive’s Base Salary accrued through the date of termination of
his employment and any other benefits the Executive is then due pursuant to the employment benefit plans of the Company. 
 (d) Upon termination of Executive’s employment for death or due to Total Disability, the Company shall pay to the Executive, guardian, personal representative or estate, as the case may be, in addition to any insurance or disability
benefits to which Executive may be entitled hereunder, all amounts accrued or vested prior to such termination. 
 (e) Upon
termination of Executive’s employment for death, due to Total Disability or without Cause, the Executive, or the Executive’s guardian, personal representative or estate, as the case may be, shall be entitled to a bonus (consistent with the

  

 -4- 

 
provisions of Section 3.2 of this Agreement) for the fiscal year in which the date of termination of employment occurs, prorated for the period
of employment in such fiscal year; provided, however, that such bonus will be withheld and not deemed earned only in the event that: (i) the Company reasonably determines that Executive had not substantially met, to the extent reasonably
obtainable, Executive’s bonus related goals as of the date of termination of employment or (ii) no other similarly situated executive actually receives a bonus for such fiscal year. Any such bonus deemed earned, shall be payable at the
time in which other similarly situated Company executives receive their bonus payments. 
 (f) In the event that this
Agreement is not renewed either after the initial Term or after a renewal period, then the Company shall have no duty to make any payments or provide any benefits to the Executive pursuant to this Agreement other than payment of the amount of the
Executive’s Base Salary accrued through the date of termination of his employment and any other benefits the Executive is then due pursuant to the employment benefit plans of the Company. 
 4.6 No Disparaging Comments Upon Termination. 
 Upon termination of this Agreement, the Company will refrain from making any disparaging remarks about the Executive. Similarly, the
Executive shall refrain from making any disparaging remarks about the Company or the businesses, services, products, stockholders, officers, directors or other personnel of the Company or any of its affiliates. 
 5. Certain Covenants of the Executive. 
 5.1 Restrictive Covenants. 
 (a) The parties hereto agree that as used
herein “Confidential Information” means all information which becomes known to the Executive as a consequence of his employment by the Company and includes, but is not limited to, information about the Company’s customers, methods of
operation, prospective and executed contracts, trade secrets, business contacts, customer lists, and all technological, business, financial, accounting, statistical and personnel information regarding the Company. The parties hereto further agree
and stipulate that this Confidential Information was developed by the Company at considerable expense, that this information is a valuable asset and part of the Company’s goodwill, that this information is vital to the Company’s success
and is the sole property of the Company. 
 (b) The Executive recognizes and acknowledges that during his employment by the
Company, the Executive has, or will, become familiar with the Company’s Confidential Information. 
 (c) The Executive
recognizes and acknowledges that the Company is engaged in the business of, among other things, building satellite ground systems and equipment for command and control, integration and test, data processing and simulation (the “Business”).

  

 -5- 

 
The Business is a highly competitive enterprise, so that any unauthorized disclosure or unauthorized use by the Executive of the Confidential Information
protected under this Agreement, whether during his employment with the Company or after its termination, would cause immediate, substantial and irreparable injury to the Business and the goodwill of the Company. 
 (d) The Executive agrees that upon termination of his employment with the Company for any reason, whether voluntary or involuntary or with
or without Cause, he will surrender to the Company every item and every document which is the Company’s property or will completely remove from the Executive’s personal property such Confidential Information in whatever form (e.g. cell
phones, PDA’s, personal computers, etc.). All such documents and Confidential Information are the sole and absolute property of the Company. At the written request of the Company, the Executive shall provide the designated representative of the
Company a certificate containing the following statement: “The Executive hereby certifies that he has notified the Company’s designated representative of all Confidential Information residing on any personal property of the Executive to
which the Executive is aware of after due review and inspection and has removed and destroyed (unless otherwise directed in writing by the Company) all Confidential Information from all personal property of the Executive.” Thereafter, in the
event that the Executive becomes aware of any further Confidential Information on the Executive’s personal property, the Executive shall notify the Company in writing and again comply with the immediately preceding sentence. 
 (e) The Executive agrees that during his employment and following the termination of that employment for any reason, whether voluntary or
involuntary or with or without Cause, he will not, on his own behalf or as a partner, officer, director, employee, agent, or consultant of any other person or entity, directly or indirectly, disclose the Company’s Confidential Information to
any person or entity other than agents of the Company, and he will not use or aid others in obtaining or using any such Confidential Information. The Executive’s obligations under this Section 5.1(e) shall not be deemed violated in
the event that (i) the Executive discloses any Confidential Information pursuant to order of a court of competent jurisdiction, provided the Executive has notified the Company of such potential legal order and provided the Company with the
opportunity to challenge or limit the scope of the disclosure, or (ii) the information becomes generally available from a source other than the Company, any of its affiliates, or any of their employees when such source is not legally
prohibited, to the best of the Executive’s knowledge, from making such information available. 
 (f) All inventions,
prototypes, discoveries, improvements, innovations and the like (“Inventions”) and all works of original authorship or images that are fixed in any tangible medium of expression and all copies thereof (“Works”) which are
designed, created or developed by the Executive, solely or in conjunction with others, in the course of performance of the Executive’s duties which relate to the Business, shall be made or conceived for the exclusive benefit of and shall be the
exclusive property of the Company. The Executive shall immediately notify the Company upon the design, creation or development of all Inventions and Works. At any time thereafter, the Executive, at the request and expense of the Company, shall
execute and deliver to the Company all documents or instruments which may be necessary to secure or 

  

 -6- 

 
perfect the Company’s title to or interest in the Inventions and Works, including but not limited to applications for letters of patent, and extensions,
continuations or reissues thereof, applications for copyrights and documents or instruments of assignment or transfer. All Works are agreed and stipulated to be “works made for hire,” as that term is used and understood within the
Copyright Act of 1976, as amended or any successor statute. To the extent any Works are not deemed to be works made for hire as defined above, and to the extent that title to or ownership of any Invention or Work and all other rights therein are not
otherwise vested exclusively in the Company, the Executive shall, without further consideration but at the expense of the Company, assign and transfer to the Company the Executive’s entire right, title and interest (including copyrights and
patents) in or to those Inventions and Works. 
 (g) The Executive agrees that during his employment with the Company and for
a period commencing on the termination of such employment and ending (i) in the event the Executive’s employment is terminated in accordance with Section 2 by the Company without Cause, at the end of the Termination Coverage
Period, or (ii) in the event the Executive’s employment terminates for any other reason (whether voluntarily or involuntarily), on the date one (1) year following such date of termination, he will not, on his own behalf or as a
partner, officer, director, employee, agent, or consultant of any other person or entity, directly or indirectly, engage or attempt to engage in a business which competes against the Business of the Company in any geographic area in which the
Company engages in the Business. This subsection shall not be construed as precluding the Executive from working as an employee or consultant for a separate business unit of a competitor of the Company, if the separate business unit is not in
competition with the Business. 
 (h) The Executive agrees that during his employment and for a period of twenty four
(24) months after the termination of such employment, whether voluntary or involuntary or with or without Cause, he will not, on his own behalf or as a partner, officer, director, employee, agent, or consultant of any other person or entity,
directly or indirectly, solicit or induce (or attempt to solicit or induce) any employees of the Company to leave their employment with the Company and/or consider employment with any other person or entity. 
 5.2 Rights and Remedies Upon Breach. If the Executive breaches, or threatens, either in writing or as evidenced by a
demonstrable course of conduct, to commit a breach of, any of the provisions of Section 5.1 (the “Restrictive Covenants”), the Company shall, in addition to its right immediately to terminate this Agreement, have the right and
remedy (which right and remedy shall be independent of others and severally enforceable, and which shall be in addition to, and not in lieu of, any other rights and remedies available to the Company under law or in equity) to have the Restrictive
Covenants specifically enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such breach or threatened breach could cause irreparable injury to the Company or its affiliates and that money damages may not
provide adequate remedy to the Company. 
 5.3 Covenants Currently Binding the Executive. The Executive
warrants that his employment by the Company, and his execution, delivery and performance of this Agreement, will not (a) violate any non-disclosure agreements, covenants against competition, or 

  

 -7- 

 
other restrictive covenants made by the Executive to or for the benefit of any previous employer or partner, or (b) violate or constitute a breach or
default under, any statute, law, judgment, order, decree, writ, injunction, deed, instrument, contract, lease, license or permit to which the Executive is a party or by which the Executive is bound. 
 5.4 Litigation. There is no litigation, proceeding or investigation of any nature (either civil or
criminal) which is pending or, to the best of the Executive’s knowledge, threatened against or affecting the Executive or which would adversely affect his ability to substantially perform the duties herein. 
 5.5 Review. The Executive has received or been given the opportunity to review the provisions of this
Agreement, and the meaning and effect of each provision, with independent legal counsel of the Executive’s choosing. 
 5.6 Severability of Covenants. The Executive acknowledges and agrees that the Restrictive Covenants are reasonable and valid in geographical and temporal scope and in all respects. If any court determines that any of
the Restrictive Covenants, or any part thereof, is invalid or unenforceable, the remainder of the Restrictive Covenants shall not thereby be affected and shall be given full effect, without regard to the invalid portions. 
 5.7 Blue-Penciling. If any court determines that any of the Restrictive Covenants, or any part thereof, is
unenforceable because of the duration or geographic scope of such provision, such court shall have the power to reduce the duration or scope of such provision, as the case may be, and, in its reduced form, such provision shall then be enforceable
and shall be enforced. If any such court declines to so revise such covenant, the parties agree to negotiate in good faith a modification that will make such duration or scope enforceable. 
  

 -8- 

 6. Dispute Resolution. 
 6.1 Costs of Arbitration. If either party brings an arbitration proceeding to enforce its rights under this
Agreement, the substantially prevailing party (as determined by the arbitrator) shall be entitled to recover from the other party all expenses incurred by it in preparing for and in trying the case, including, but not limited to, investigative
costs, court costs and reasonable attorneys’ fees. 
 6.2 No Jury Trial. NEITHER PARTY SHALL ELECT A
TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN ANY WAY CONNECTED WITH A BREACH OF THIS AGREEMENT. 
 6.3 Personal Jurisdiction. Both parties agree to submit to the jurisdiction and venue of the state courts in the State of Maryland as to matters involving enforcement of this Agreement including
any award under an arbitration proceeding. 
 6.4 Arbitration. SUBJECT TO THE
COMPANY’S RIGHT TO SEEK INJUNCTIVE RELIEF AS SPECIFIED IN THIS AGREEMENT, ANY DISPUTE BETWEEN THE PARTIES HERETO ARISING UNDER OR RELATING TO THIS AGREEMENT (INCLUDING, BUT NOT LIMITED TO, THE AMOUNT OF DAMAGES, THE NATURE OF THE
EXECUTIVE’S TERMINATION OR THE CALCULATION OF ANY BONUS OR OTHER AMOUNT OR BENEFIT DUE) SHALL BE RESOLVED IN ACCORDANCE WITH THE PROCEDURES OF THE AMERICAN ARBITRATION ASSOCIATION. ANY RESULTING HEARING SHALL BE HELD IN LANHAM, MARYLAND. THE
RESOLUTION OF ANY DISPUTE ACHIEVED THROUGH SUCH ARBITRATION SHALL BE BINDING AND ENFORCEABLE BY A COURT OF COMPETENT JURISDICTION.

the drawing. The Borrower’s obligation to reimburse the Lender for any drawing under a Letter of Credit shall be absolute and unconditional, irrespective of any rights of set-off, counterclaim or defense to payment Borrower may claim or have
against the Lender, the beneficiary of the Letter of Credit or any other Person;

 To induce the Lender to enter into this Agreement and to extend the Revolving Loan to Borrower and to issue Letters of Credit, Borrower, jointly and severally, makes the following representations and warranties to the
Lender: 
 5.1 Corporate Authority; Subsidiaries. Borrower and each of its Subsidiaries (i) is a corporation or limited liability
company duly organized, validly existing, and in good standing under the laws of its State of organization, (ii) is qualified to do business as a foreign corporation and is in good standing in all jurisdictions where its activities or ownership
of property require such qualification, 

  

 -16- 

 
except for any such failure to be so qualified which may reasonably be expected to result in a Material Adverse Change, and (iii) has the full and
unrestricted power and authority, corporate and otherwise, to own, operate and lease its properties, to carry on its business as currently conducted, to execute and deliver and perform the Loan Documents to which it is a party, to incur the
obligations provided for herein and therein, and to perform the transactions contemplated hereby and thereby, all of which have been duly and validly authorized by all proper and necessary action (all of which actions are in full force and effect).
Except as set forth in Schedule 4.1 hereof, Borrower has no Subsidiaries. 
 5.2 Approvals. Borrower has provided Lender with a
true and accurate certificate of the resolutions adopted by its governing body authorizing the loan transactions contemplated by this Agreement. No further approval, consent, notice to or other action by any other Person (including, without
limitation, the stockholders or other equity holders of Borrower or any of its Subsidiaries or any Governmental Authority) is or will be necessary to permit the valid execution, delivery or performance by Borrower of this Agreement or any of the
other Loan Documents. 
 5.3 Binding Effect, No Violations. Each of the Loan Documents, upon its execution and delivery, will
constitute a legal, valid and binding obligation of Borrower and its Subsidiaries party thereto, enforceable against Borrower and its Subsidiaries in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). The execution, delivery and performance of
the Loan Documents will not (i) violate, conflict with or constitute a default (with due notice, lapse of time or both) under any law, regulation, order or any other requirement of any court, tribunal, arbitrator or other Governmental
Authority, any terms of the Governance Documents of Borrower or any of its Subsidiaries, or any contract, agreement or other arrangement binding upon or affecting Borrower or any of its Subsidiaries or any of their respective properties, or
(ii) result in the creation, imposition or acceleration of any indebtedness or any Encumbrance of any nature upon, or with respect to, Borrower or any of its Subsidiaries or any of their respective properties. 
 5.4 Litigation. Without limiting Borrower’s representation and warranty in Section 5.21 hereof, except as previously disclosed to
the Lender in writing or in filings made by Borrower with the SEC, there is no judgment, order, claim, litigation, proceeding or investigation pending or, to the knowledge of Borrower, threatened against or affecting Borrower or any of its
Subsidiaries, their respective properties or business or this Agreement or any of the other Loan Documents or any of the transactions contemplated hereby or thereby before or by any court, tribunal, arbitrator or other Governmental Authority
involving an aggregate amount in dispute in excess of Two Million Dollars ($2,000,000.00). 
 5.5 Title to and Condition of Assets.
Borrower and each of its Subsidiaries has good, valid and marketable title to all of its properties and assets (whether real or personal) free and clear of all Encumbrances other than Permitted Liens. All personal property of Borrower or any of its
Subsidiaries which is necessary for Borrower’s or its Subsidiary’s operations is in good operating condition and repair, normal wear and tear excepted, and is suitable and adequate for the uses for which it is being used. 
  

 -17- 

 5.6 Loan Application. The statements (other than projections) made and the documents delivered by
Borrower or any of its Subsidiaries to the Lender (including, without limitation, any financial statements) in connection with its application for the Revolving Loan, when taken as a whole, are true, correct and complete in all material respects,
omit no material facts, are not misleading, and present fairly the condition (financial or otherwise) of Borrower and its Subsidiaries. The projections contained in the materials referenced above are based upon reasonable estimates and assumptions,
all of which are reasonable in light of the conditions which existed at the time the projections were made, and reflect the good faith estimate of the Borrower of the results of operations and other information projected therein, provided
that no representation is made that the assumptions will prove to be correct. 
 5.7 No Change. No Material Adverse Change has
occurred since June 30, 2007. 
 5.8 Taxes. Borrower and each of its Subsidiaries has timely filed all tax returns and other
material reports required by any Governmental Authority to be filed by Borrower and its Subsidiaries, and such returns and reports are, after due inquiry, reasonably believed to be true and correct at the time of filing thereof. Borrower and each of
its Subsidiaries has paid all taxes, assessments and other government charges imposed upon it or its income, profits or properties, or upon any part thereof, other than those presently payable without penalty or interest (or as are being contested
in good faith by appropriate proceedings and with respect to which adequate reserves are being maintained), and Borrower and each of its Subsidiaries has timely filed all claims for refunds to which it is entitled. The amounts reserved as a
liability for income and other taxes payable in the most recent financial statements of Borrower and its Subsidiaries provided to the Lender are sufficient for the payment of all unpaid federal, state, county and local income, excise, property and
other taxes, whether or not disputed, of Borrower and its Subsidiaries accrued for or applicable to the period and on the dates of such financial statements and all years and periods prior thereto, and for which Borrower or any of its Subsidiaries
may be liable in its own right or as a transferee of the assets of, or as successor to, any other Person. 
 5.9 No Event of Default.
As of the date on which this representation and warranty is made (or remade), no Event of Default, and no event which with notice, lapse of time or both would constitute an Event of Default, has occurred and is continuing. 
 5.10 Compliance with Laws, Governance Documents and Agreements. Without limiting the provisions of Section 5.3, Borrower and each of
its Subsidiaries has complied and is in full compliance with (a) each agreement binding upon or affecting Borrower, its Subsidiaries or any of their respective properties except to the extent the failure to comply with such agreements would not
have a Material Adverse Effect, (b) all applicable laws, ordinances, rules, regulations, judgments, orders, writs, injunctions, decrees, rules, 

  

 -18- 

 
awards and other requirements of each Governmental Authority, court, tribunal, commission, board, bureau, arbitration panel or arbitrator except to the
extent the failure to comply therewith would not have a Material Adverse Effect, and (c) all terms and conditions of its Governance Documents. Neither Borrower nor any of its Subsidiaries is in default with respect to any Debt, except as would
not constitute an Event of Default under Section 9.1(k) hereof. Without limiting the generality of the foregoing, Borrower represents to Lender that: (1) Borrower has previously disclosed to Lender in writing all activities of
Borrower and its Subsidiaries that involve the use, manufacturing, storage, disposal, emission, discharge, generation or transportation of Hazardous Wastes, Toxic Substances or other materials regulated by Environmental Laws; (2) Borrower and
its Subsidiaries have complied and are in full compliance with all Environmental Laws; (3) Borrower and its Subsidiaries maintain in full force and effect all permits required by Environmental Laws; and (4) there exists no pending or
threatened litigation, order, ruling, notice or investigation regarding the use, manufacturing, storage, disposal, emission, discharge generation or transportation of Hazardous Wastes or Toxic Substances by Borrower or any of its Subsidiaries or
regarding any violation or alleged violation of any Environmental Laws. 
 5.11 Licenses and Contracts. All franchises, licenses,
trademarks, trade names, copyrights, patents, permits, certificates, consents, approvals, authorizations, agreements and contracts necessary to operate the business of Borrower and its Subsidiaries and to own or lease their respective property
(collectively, “Permits”) have been obtained and are in effect and Borrower and its Subsidiaries are in compliance therewith and the Permits are free from challenge, except, in each case, to the extent the failure to do so would not have a
Material Adverse Effect. Borrower has no knowledge, and neither Borrower nor any of its Subsidiaries has received any notice to the effect, that any product manufactured or for sale by Borrower or any of its Subsidiaries, or any service it renders,
or any process, method, know-how, trade secret, part or material it employs in the manufacture of any product it makes or sells or any service it renders, or the marketing or use by it or another of any such product or service, may infringe any
trademark, trade name, copyright, patent, trade secret or legally protected right of any other Person, except for any such infringements, individually or in the aggregate, that would not have a Material Adverse Effect. 
 5.12 Intellectual Property. Borrower and each of its Subsidiaries (a) owns all right, title and interest in and to all Intellectual Property
used in and material to the operation of its business, and (b) with respect to any Intellectual Property used in and material to the operation of its business that is not owned by Borrower or such Subsidiary, possesses adequate licenses or
other legally enforceable rights to use the same except to the extent the failure to possess the same would not have a Material Adverse Effect. Neither Borrower nor any of its Subsidiaries has reason to believe that any valid basis exists upon which
a claim adversely affecting any such Intellectual Property may be asserted against Borrower or its Subsidiaries. To the best knowledge of the Borrower, no Person is infringing upon the Intellectual Property used by Borrower or any of its
Subsidiaries material to the operation of their respective businesses. Borrower and each of its Subsidiaries has taken appropriate steps to protect the secrecy, confidentiality and value of their respective rights in and to such Intellectual
Property and to prevent others from using such Intellectual Property without consent. 
  

 -19- 

 5.13 Disclosure. No representation or warranty of Borrower or any of its Subsidiaries contained in
this Agreement or any of the Loan Documents and no written statement of fact furnished or to be furnished by Borrower or any of its Subsidiaries to the Lender pursuant to this Agreement or any of the Loan Documents, when viewed together, contains or
will contain any untrue statement of a fact material to the condition (financial or otherwise) of Borrower and its Subsidiaries, or omits or will omit to state any material fact necessary in order to make the statements contained herein or therein,
or furnished herewith or therewith, not misleading. 
 5.14 Margin Securities. Neither Borrower nor any of its Subsidiaries is engaged
in the business of extending credit for the purpose of purchasing or carrying any “margin stock” within the meaning of Regulation U of the Board of Governors of the Federal Reserve System, as amended.

 5.16

 (a) During the five-year period prior to the date on which this representation is made or deemed made; (i) no Termination Event has occurred, and, to the best of Borrower’s knowledge, no event or condition
has occurred or exists as a result of which any Termination Event could reasonably be expected to occur, with respect to any Plan; (ii) no “accumulated funding deficiency,” as such term is defined in Section 302 of ERISA and
Section 412 of the Code, whether or not waived, has occurred with respect to any Plan; (iii) each Plan has been maintained, operated and funded in compliance with its own terms and in material compliance with the provisions of ERISA, the
Code, and any other applicable federal or state laws; and (iv) no lien in favor of the PBGC or a Plan has arisen or is reasonably likely to arise on account of any Plan. 
 (b) The actuarial present value of all “benefit liabilities” under each Single Employer Plan (determined within the meaning of
Section 401(a)(2) of the Code, utilizing the actuarial assumptions used to fund such Plans), whether or not vested, did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the
current value of the assets of such Plan allocable to such accrued liabilities. 
 (c) Neither Borrower nor any of its Subsidiaries nor any
ERISA Affiliate has incurred or, to the best of Borrower’s knowledge, are reasonably expected to incur any withdrawal liability under ERISA to any Multiemployer Plan or Multiple Employer Plan. Neither Borrower, any of its Subsidiaries nor any
ERISA Affiliate has received any notification that any Multiemployer Plan is in reorganization (within the meaning of Section 4241 of ERISA), is insolvent (within the meaning of Section 4245 of ERISA), or has been terminated (within the
meaning of Title IV of ERISA), and no Multiemployer Plan is, to the best knowledge of Borrower, reasonably expected to be in reorganization, insolvent or terminated.

the Code) or breach of fiduciary responsibility has occurred with respect to a Plan which has subjected or may subject Borrower or any of its Subsidiaries or any ERISA Affiliate to any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or
Section 4975 of the Code, or under any agreement or other instrument pursuant to which Borrower or any of its Subsidiaries or any ERISA Affiliate has agreed or is required to indemnify any Person against any such liability.

 6.1 Payment of Loan. The Borrower shall punctually make the payments on the Loan at the times and places and in the manner specified in the Revolving Note.

remain qualified as a foreign corporation in each jurisdiction in which such qualification is necessary or desirable in view of their respective activities and ownership of their respective property, except for any such failure to be so qualified
which may reasonably be expected to result in a Material Adverse Change; and (c) continue to engage in a business of the same general type as now conducted by it and conduct such business in an orderly, efficient and regular manner
substantially consistent with the conduct of its business immediately prior to the date of this Agreement. 
 6.4 Taxes, Charges and
Obligations. Borrower shall, and shall cause each of its Subsidiaries to, pay and discharge all taxes, assessments and governmental charges or levies imposed upon it or upon its income, profits, properties or any part thereof, prior to the date
on which penalties attach thereto, as well as all claims which, if unpaid, might become an Encumbrance upon any of its properties, and pay, discharge or otherwise satisfy at or before maturity or before they become delinquent, as the case may be,
all of its indebtedness and other obligations of whatever nature; however, neither Borrower nor any of its Subsidiaries shall be required to pay any such tax, assessment, charge, levy, claim, indebtedness or obligation so long as (i) the
validity thereof is being contested by Borrower or such Subsidiary in good faith and by proper proceedings, and (ii) Borrower or such Subsidiary, as the case may be, sets aside on its books adequate reserves therefor.

negligence or willful misconduct.

such Investment, Borrower shall be in compliance with the financial covenants set forth in Section 6.13 hereof on a pro forma basis (such pro forma calculation to be certified by the Chief Financial Officer of 

  

 -29- 

 
Integral in a form reasonably satisfactory to the Lender and delivered to Lender at least ten (10) Business Days prior to the consummation of the
proposed Investment). For purposes hereof, “pro forma basis” shall mean the recalculation of the financial covenants set forth in Section 6.13 hereof based on the pro forma historical financial information of Borrower and its
Subsidiaries, on a consolidated basis, after giving effect to such Investment (a) as of the last day of Integral’s most recent fiscal year end, and (b) if applicable, as of the last day of the most recent interim fiscal quarter for

 7.8 Other Agreements. Enter into any agreement or undertaking containing any provision which would be violated or breached by Borrower’s
performance of its obligations under the Loan Documents.

 ARTICLE 8. Intentionally Omitted. 
 ARTICLE 9. EVENTS OF DEFAULT AND REMEDIES.

 -31- 

 (d) any representation or warranty made by or on behalf of Borrower or any of its Subsidiaries herein or

 (i) any Government Contract is terminated for default of Borrower or any of its Subsidiaries and such Government Contract, immediately prior to such
termination, has potential remaining revenue to Borrower of at least Five Million Dollars ($5,000,000.00); or 
 (j) any of the following
events or conditions shall occur: (1) any “accumulated funding deficiency,” as such term is defined in Section 302 of ERISA and Section 412 of the Code, whether or not waived, shall exist with respect to any Plan, or any
lien shall arise on the assets of Integral or any of its Subsidiaries or any ERISA Affiliate in favor of the PBGC or a Plan; (2) a Termination Event shall occur with respect to a Single Employer Plan, which, in the Lender’s opinion, is

(i) the termination of such Plan for purposes of Title IV of ERISA, or 

  

 -32- 

 
(ii) Integral or any of its Subsidiaries or any ERISA Affiliate incurring any liability in connection with a withdrawal from, reorganization of (within the

agreement or other instrument pursuant to which Integral or any of its Subsidiaries or any ERISA Affiliate has agreed or is required to indemnify any person against any such liability; or

(ii) after giving effect to any applicable notice and cure periods, fails to observe or perform any other agreement or condition relating to such Debt or contained in any instrument or agreement evidencing, securing or relating thereto, or any
other event occurs, the effect of which default or other event is to cause, or to permit the holder or holders or the beneficiary or beneficiaries of such Debt (or a trustee or agent on behalf of such holder or holders or beneficiary or
beneficiaries) to cause, with the giving of notice if required, such Debt to be demanded or to become due or to be purchased, repurchased, prepaid, defeased or redeemed (automatically or otherwise), or an offer to purchase, repurchase, prepay,
defease or redeem such Debt to be made, prior to its stated maturity, or cash collateral in respect thereof to be demanded; or

Subsidiaries and the same shall remain undischarged for a period of thirty (30) consecutive days during which execution shall not be effectively stayed, or any action shall be legally taken by a judgment creditor to attach or levy upon any
material assets of Integral or any of its Subsidiaries to enforce any such judgment; or 
 (m) any of the Loan Documents shall for any reason
cease to be, or shall be asserted by any Person obligated thereunder not to be, a legal, valid and binding obligation of such Person. 
 9.2
Rights and Remedies of the Lender. Upon the occurrence of any Event of Default, the Lender may, at its option, exercise any one or more of the rights and remedies exercisable by the Lender under other provisions of this Agreement, under any
of the other Loan Documents, or provided by applicable law. Without limiting the foregoing, upon the occurrence of (i) an Event of Default due to a breach of Section 6.12 of this Agreement, the Lender may, at its option, adjust the
applicable interest rate under the Revolving Note and/or fees due and payable by Borrower under this Agreement or any other Loan Document to maintain Lender’s required rate of return, or (ii) any Event of Default, the Lender may, at its
option, declare this Agreement and the Lender’s obligation to 

  

 -33- 

 
make or extend any Advances on the Revolving Loan or issue Letters of Credit to be terminated, require Borrower to provide cash collateral in an amount equal
to the LOC Obligations and declare the entire unpaid principal amounts of the Revolving Loan, all interest accrued and unpaid thereon, and all other amounts payable under this Agreement and the other Loan Documents to be accelerated, and to be
immediately due and payable (except that upon the occurrence of an Event of Default under Section 9.1(e) or Section 9.1(f), such acceleration shall occur automatically and immediately without any declaration or other action
on the part of the Lender) whereupon the Lender’s obligation to make or extend any Advances on the Revolving Loan or issue Letters of Credit shall be automatically terminated, all such accrued interest and all such other amounts shall become
and be immediately due and payable, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Borrower, anything contained herein or in any of the other Loan Documents to the contrary
notwithstanding. 
 ARTICLE 10. MISCELLANEOUS PROVISIONS. 
 10.1 Additional Actions and Documents. Borrower shall take or cause to be taken such further actions, shall execute, deliver and file or cause to

 10.4 Severability. If fulfillment of any provision of the Loan Documents or performance of any transaction related
thereto, at the time such fulfillment or performance shall be due, shall involve transcending the limit of validity prescribed by law, then the obligation to be fulfilled or performed shall be reduced to the limit of such validity; and if any clause
or provision contained in any Loan Document operates or would operate prospectively to invalidate any Loan Document, in whole or in part, then such clause or provision only shall be held ineffective, as though not herein or therein contained, and

 10.5 Survival. It is the express intention
and agreement of the parties hereto that all covenants, agreements, statements, representations, warranties and indemnities made by Borrower in the Loan Documents shall survive the execution and delivery of the Loan Documents and the making of all

conditions expressly waived. 
 10.7 Rights Cumulative. The rights and remedies of the Lender described in any of the Loan Documents
are cumulative and not exclusive of any other rights or remedies which the Lender otherwise would have at law or in equity or otherwise. No notice to or demand on Borrower in any case shall entitle Borrower to any other notice or demand in similar
or other circumstances. 
 10.8 Entire Agreement; Modification; Benefit. This Agreement, the schedules and exhibits hereto, and the
other Loan Documents constitute the entire agreement of the parties hereto with respect to the matters contemplated herein, supersede all prior oral and written agreements with respect to the matters contemplated herein, and may not be modified,
deleted or amended except by written instrument executed by the parties. All terms of this Agreement and of the other Loan Documents shall be binding upon, and shall inure to the benefit of and be enforceable by, the parties hereto and their
respective successors and assigns; however, Borrower may not assign or transfer any of its rights or obligations hereunder without the prior written consent of the Lender. In the event of any conflict between the terms of this Agreement and the
terms of the other Loan Documents, the terms of this Agreement shall control. 
 10.9 Setoff. In addition to any rights or remedies of
the Lender provided by law, upon the occurrence of any Event of Default hereunder, the Lender is irrevocably authorized, at any time or times without prior notice to Borrower, to set off, appropriate and apply any and all deposits, credits,
indebtedness or claims at any time held or owing by the Lender to or for the credit or the account of Borrower, in such amounts as the Lender may elect, against and on account of the obligations and liabilities of Borrower to the Lender hereunder or
under any of the other Loan Documents, whether or not the Lender has made any demand for payment, and although such obligations and liabilities may be contingent or unmatured. 
 10.10 Governing Law; Construction. This Agreement and the other Loan Documents, the rights and obligations of the parties hereto, and any claims
or disputes relating thereto shall be governed by and construed in accordance with the laws of the State of New York (excluding any choice of law rules thereof that would require the application of the laws of another jurisdiction). Each party
hereto hereby acknowledges that all parties hereto participated equally in the negotiation and drafting of this Agreement and that, accordingly, no court construing this Agreement shall construe it more stringently against one party than against the
other. 
 10.11 Pronouns. All pronouns and any variations thereof shall be deemed to refer to the masculine, feminine, neuter,
singular or plural, as the identity of the Person may require.

 10.12 Headings. Article, section and subsection headings contained in this Agreement are inserted
for convenience of reference only, shall not be deemed to be a part of this Agreement for any purpose, and shall not in any way define or affect the meaning, construction or scope of any of the provisions hereof. 
 10.13 Payments. If any payment or performance of any of the obligations under this Agreement or any of the other Loan Documents becomes due on a
day other than a Business Day, the due date shall be extended to the next succeeding Business Day, and interest thereon (if applicable) shall be payable at the then applicable rate during such extension. 
 10.14 Accounting Terms. All accounting terms used herein which are not otherwise expressly defined in this Agreement shall have the meanings
respectively given to them in accordance with GAAP in effect on the date of this Agreement. Except as otherwise provided herein, all financial computations made pursuant to this Agreement shall be made in accordance with GAAP, consistently applied,
and all balance sheets and other financial statements shall be prepared in accordance with GAAP, consistently applied. 
 10.15
Execution. To facilitate execution, this Agreement and any of the other Loan Documents may be executed in as many counterparts as may be required; and it shall not be necessary that the signature of, or on behalf of, each party, or the
signatures of all persons required to bind any party, appear on each counterpart; but it shall be sufficient that the signature of, or on behalf of, each party, or the signatures of the persons required to bind any party, appear on one or more of
the counterparts. All counterparts shall collectively constitute a single agreement. It shall not be necessary in making proof of this Agreement or any other Loan Document to produce or account for any particular number of counterparts; but rather
any number of counterparts shall be sufficient so long as those counterparts contain the respective signatures of, or on behalf of, all of the parties hereto. 
 10.16 Consent to Jurisdiction. Subject to any provision of this Agreement requiring that disputes be submitted to arbitration, Borrower irrevocably consents to the exclusive jurisdiction of any state or federal
court sitting in the State of Maryland over any suit, action, or proceeding arising out of or relating to this Agreement or the other Loan Documents. Borrower irrevocably waives, to the fullest extent permitted by law, any objection that Borrower
may now or hereafter have to the laying of venue of any such suit, action, or proceeding brought in any such court, or any claim that any such suit, action, or proceeding brought in any such court has been brought in an inconvenient forum. Final
judgment in any such suit, action, or proceeding brought in any such court shall be conclusive and binding upon the Borrower. 
 10.17
Service of Process. Borrower consents to process being served in any suit, action or proceeding by mailing a copy thereof by registered or certified mail postage prepaid, return receipt requested, to the Borrower’s address specified in
or designated in this Agreement. Borrower agrees that such service (i) shall be deemed in every respect effective service of process upon Borrower in any 

  

 -37- 

 
such suit, action or proceeding, and (ii) shall, to the fullest extent permitted by law, be taken and held to be valid personal service upon and
personal delivery to Borrower. Nothing in this Section shall affect the right of the Lender to serve process in any manner permitted by law, or limit any right that the Lender may have to bring proceedings against Borrower in the courts of any
jurisdiction or to enforce in any lawful manner a judgment obtained in one jurisdiction in any other jurisdiction. 
 10.18 Sale of Loan
Documents; Disclosure of Information. Borrower hereby consents to and agrees that Lender may disclose to any Person any and all information connected with or related to the Revolving Loan or other Loan Documents (a) as may be required under
applicable law, (b) as may be required by any government agency, tribunal, court or arbitrator, or (c) on a confidential basis, for the purpose of selling or assigning any rights of Lender in the Loan Documents. The information which may
be disclosed by Lender (if permitted by the prior sentence) includes but is not limited to all Loan Documents, credit files and correspondence files and all other writings and oral communications which Lender wishes to disclose, in its sole and
absolute discretion. Lender, with the consent of Borrower (which consent shall not be unreasonably withheld, conditioned or delayed), may sell or assign any rights of Lender in any or all of the Loan Documents to any Person; provided,
however, no such consent of Borrower shall be required if and Event of default has occurred and is continuing. 
 10.19
ARBITRATION; WAIVER OF JURY TRIAL. This Section, including the subparagraphs below, is referred to as the “Dispute Resolution Provision.” This Dispute Resolution Provision is a material inducement for the parties hereto in
entering into this Agreement and the other Loan Documents. 
 (a) This Dispute Resolution Provision concerns the resolution of any
controversies or claims between the parties hereto, whether arising in contract, tort or by statute, including, but not limited to, controversies or claims that arise out of or relate to: (i) this Agreement (including any renewals, extensions
or modifications), or (ii) any other Loan Document (collectively a “Claim”). For the purposes of this Dispute Resolution Provision only, the term “parties” shall include any parent corporation, subsidiary or affiliate of the
Lender involved in the servicing, management or administration of any obligation described or evidenced by this agreement. 
 (b) At the
request of any party to this Agreement, any Claim shall be resolved by binding arbitration in accordance with the Federal Arbitration Act (Title 9, U.S. Code) (the “Act”). The Act will apply even though this Agreement or any other
applicable Loan Document provides that it is governed by the law of a specified state. 
 (c) Arbitration proceedings will be determined in
accordance with the Act, the then-current rules and procedures for the arbitration of financial services disputes of the American Arbitration Association or any successor thereof (“AAA”), and the terms of this Dispute Resolution Provision.
In the event of any inconsistency, the terms of this Dispute Resolution Provision shall control. If AAA is unwilling or unable to (i) serve as the provider of arbitration, or (ii) enforce any provision of this Section, the Lender may
designate another arbitration organization with similar procedures to serve as the provider of arbitration. 
  

 -38- 

 (d) The arbitration shall be administered by AAA and conducted, unless otherwise required by law, in
Montgomery County, Maryland. All Claims shall be determined by one arbitrator; however, if Claims exceed Five Million Dollars ($5,000,000), upon the request of any party, the Claims shall be decided by three arbitrators. All arbitration hearings
shall commence within ninety (90) days of the demand for arbitration and close within ninety (90) days of commencement and the award of the arbitrator(s) shall be issued within thirty (30) days of the close of the hearing. However,
the arbitrator(s), upon a showing of good cause, may extend the commencement of the hearing for up to an additional sixty (60) days. The arbitrator(s) shall provide a concise written statement of reasons for the award. The arbitration award may
be submitted to any court having jurisdiction to be confirmed and have judgment entered and enforced. 
 (e) The arbitrator(s) will give
effect to statutes of limitation in determining any Claim and may dismiss the arbitration on the basis that the Claim is barred. For purposes of the application of any statutes of limitation, the service on AAA under applicable AAA rules of a notice
of Claim is the equivalent of the filing of a lawsuit. Any dispute concerning this Section or whether a Claim is arbitrable shall be determined by the arbitrator(s), except as set forth in Section 10.19(i) of this Agreement. The
arbitrator(s) shall have the power to award legal fees pursuant to the terms of this Agreement or any other Loan Document. 
 (f) The
procedure described in this Section will not apply if the Claim, at the time of the proposed submission to arbitration, arises from or relates to an obligation to the Lender secured by real property. In any such case, all of the parties to this
Agreement must consent to submission of the Claim to arbitration. 
 (g) To the extent any Claims are not arbitrated, to the extent permitted
by law the Claims shall be resolved in court by a judge without a jury. 
 (h) This Dispute Resolution Provision does not limit the right of
any party to: (i) exercise self-help remedies, such as but not limited to, setoff; (ii) initiate judicial or non-judicial foreclosure against any real or personal property collateral; (iii) exercise any judicial or power of sale
rights, or (iv) act in a court of law to obtain an interim remedy, such as but not limited to, injunctive relief, writ of possession or appointment of a receiver, or additional or supplementary remedies. The filing of a court action is not
intended to constitute a waiver of the right of any party, including the suing party, thereafter to require submittal of the Claim to arbitration or judicial reference. 
 (i) Any arbitration, judicial reference or trial by a judge of any Claim will take place on an individual basis without resort to any form of class or representative action (the “Class Action Waiver”).
Regardless of anything else in this Dispute Resolution Provision, the validity and effect of the Class Action Waiver may be determined only by a court or referee and not by an arbitrator. The parties to this Agreement acknowledge that the Class
Action Waiver is material and essential to the arbitration of any disputes between the 

  

 -39- 

 
parties and is nonseverable from the agreement to arbitrate Claims. If the Class Action Waiver is limited, voided or found unenforceable, then the
parties’ agreement to arbitrate shall be null and void with respect to such proceeding, subject to the right to appeal the limitation or invalidation of the Class Action Waiver. The parties hereto acknowledge and agree that under no
circumstances will a class action be arbitrated. 
 (j) By agreeing to binding arbitration or judicial reference, the parties hereto
irrevocably and voluntarily waive any right they may have to a trial by jury as permitted by law in respect of any Claim. Furthermore, without intending in any way to limit this Dispute Resolution Provision, to the extent any Claim is not arbitrated
or submitted to judicial reference, the parties irrevocably and voluntarily waive any right they may have to a trial by jury to the extent permitted by law in respect of such Claim. This waiver of jury trial shall remain in effect even if the Class
Action Waiver is limited, voided or found unenforceable. WHETHER THE CLAIM IS DECIDED BY ARBITRATION, BY JUDICIAL REFERENCE, OR BY TRIAL BY A JUDGE, THE PARTIES AGREE AND UNDERSTAND THAT THE EFFECT OF THIS AGREEMENT IS THAT THEY ARE GIVING UP THE
RIGHT TO TRIAL BY JURY TO THE EXTENT PERMITTED BY LAW. 
 10.20 Joint and Several Obligations. Each Person included in the term
“Borrower” hereby irrevocably and unconditionally agrees that it is jointly and severally liable for all of the liabilities, obligations, covenants and agreements of the Borrower hereunder and under the other Loan Documents, whether now or
hereafter existing or due or to become due. The obligations under the Loan Documents of any Person included in the term “Borrower” may be enforced by the Lender against any one or more of such Person or all of them in any manner or order
selected by the Lender in its sole discretion. Each Person included in the term “Borrower” hereby irrevocably waives (i) any rights of subrogation, and (ii) any rights of contribution, indemnity or reimbursement, in each case,
that such Person may acquire or that may arise against any other Person included in the term “Borrower” due to any payment or performance made under this Agreement or any other Loan Document, in each case until all obligations of the
Borrower under this Agreement and the other Loan Documents are paid in full and performed, no Letter of Credit is outstanding and Lender has no obligation to make any further Advances or issue any Letters of Credit Obligations. Without limiting the
foregoing provisions of this Section 10.20, each Person included in the term “Borrower” acknowledges and agrees that: 
 (a) its obligations under this Agreement and each other Loan Document shall remain enforceable against it even though such obligations may be unenforceable or not allowable against any other Person included in the term “Borrower”
due to the existence of an insolvency proceeding involving such other Person; 
 (b) its obligations under this Agreement are independent of
the obligations of each other Person included in the term “Borrower”, and a separate action or actions may be brought and prosecuted against it in respect of such obligations irrespective of whether any action is brought against any such
other Person or any such other Person is joined in any such action or actions; 
  

 -40- 

 (c) it hereby irrevocably waives any defenses it may now have or hereafter acquire in any way relating
to, any or all of the following: 
 (i) any lack of validity or enforceability of this Agreement or any other Loan Document in respect of any
other Person included in the term “Borrower”; 
 (ii) any change in the time, manner or place of payment of, or in any other term
of, all or any of the obligations of any other Person included in the term “Borrower” under or in respect of this Agreement or any other Loan Document, or any other amendment or waiver of or any consent to departure from this Agreement or
any other Loan Document, in respect of any such other Person; 
 (iii) any change, restructuring or termination of the structure or existence
of any other Person included in the term “Borrower”; 
 (iv) the failure of any other Person to execute or deliver any other
agreement or the release or reduction of liability of any other Person with respect to any obligations of any Person included in the term “Borrower” under this Agreement or any other Loan Document; or 
 (v) unless the obligations of the Borrower under this Agreement and the other Loan Documents have been paid in full and performed, no Letter of Credit is
outstanding and Lender has no obligation to make any further Advances or issue any Letters of Credit Obligations, any other circumstance (including any statute of limitations) or any existence of or reliance on any representation by any other Person
that might otherwise constitute a defense available to, or a discharge of, any other Person included in the term “Borrower”; 
 (d)
its obligations under this Agreement and the other Loan Documents shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any such obligations is rescinded or must otherwise be returned by any Person upon
the insolvency, bankruptcy or reorganization of any other Person included in the term “Borrower”, all as though such payment had not been made; and 
 (e) it hereby unconditionally and irrevocably waives any right to revoke its joint and several liability under the Loan Documents and acknowledges that such liability is continuing in nature and applies to all
obligations of the Borrower under the Loan Documents, whether existing now or in the future. 
 10.21 Existing Loan Agreement. This
Agreement amends and restates in its entirety the Existing Loan Agreement. Effective as of the date hereof, the Existing Loan Agreement shall be deemed terminated and of no further force and effect except with respect to 

  

 -41- 

 
those provisions that, pursuant to the terms and provisions of the Existing Loan Agreement, expressly survive the termination of the Existing Loan Agreement.
