 2.2 Commitment Fee, Accrued Commitment
Fee.

2.3 Reimbursement Obligation; SAI Right to Require Assignment. 

(a) SAI hereby unconditionally and irrevocably agrees to reimburse GS (i) for any payment or disbursement made by GS (or its
Affiliate, as the case may be) pursuant to the Reimbursement Agreement to the Issuing Bank for honoring any demand under the Letter of Credit or (ii) for any application of CMS Cash Collateral by an Issuing Bank to reimburse said Issuing Bank
for a draw under a Letter of Credit (each, a “Reimbursement Claim”) on the day on which GS notifies SAI in writing that GS has made such payment or disbursement or a Servicer has made such withdrawal (the “Reimbursement Claim Payment
Date”). Such Reimbursement Claim shall accrue interest at a rate per annum equal to the Interest Rate from the making of such payment or disbursement by GS until an Event of Default occurs in respect of such Reimbursement Claim Payment Date,
which interest shall be due and payable in cash on the earlier of that date when the Reimbursement Claim is paid or the Reimbursement Claim Payment Date. Any Reimbursement Claim not reimbursed on or before the occurrence of an Event of Default in
respect of Reimbursement Claim Payment Date shall thereafter bear interest from such date to the date that GS is reimbursed by SAI, payable on demand, at a rate per annum equal to the Overdue Rate. GS shall also use its best efforts notify SAI
whenever GS receives notice from the Issuing Bank that it has received a demand under the Letter of Credit; provided that the failure of GS to so notify SAI shall not affect the rights of GS in any manner whatsoever. 

(b) SAI’s reimbursement obligations in respect of a Reimbursement Claim hereunder shall be irrevocable and unconditional under all
circumstances, including (i) any lack of validity or enforceability of the Letter of Credit, this Agreement or any other Financing Document, (ii) the existence of any claim, set-off, defense or other right which SAI or any of its
Affiliates may have at any time against the Servicers, GS, the Issuing Bank or any other Person, whether in connection with the Letter of Credit, this Agreement, any other Financing Document, the transactions contemplated herein or any unrelated
transactions (including any underlying transaction between SAI or any of its Affiliates and Servicers, GS, the Issuing Bank or any other Person), (iii) the validity, sufficiency or genuineness of any document which the Issuing Bank has
determined complies on its face with the terms of the Letter of Credit, even if such document should later prove to have been forged, fraudulent, invalid or insufficient in any respect or any statement therein shall have been untrue or inaccurate in
any respect, or (iv) the surrender or impairment of any security for the performance or observance of any of the terms hereof. 
 (c) In lieu of directly tendering payment of any Reimbursement Claim, SAI shall have the right, but not the obligation, to request that any direct or indirect Noteholder pay such Reimbursement Claim on
behalf of SAI and any direct or indirect Noteholder shall have the right but not the obligation to so agree, whereupon such payment by a direct or indirect Noteholder, if made, shall be accepted by GS as if the same had been tendered by SAI and
shall deemed to constitute a concurrent sale of a secured note by SAI in like amount to the order of such direct or indirect Noteholder under and pursuant to the terms of the Amended and Restated Securities Purchase Agreement.

 2.5 Making Payments; Setoff; Taxes.

time by GS) not later than noon, local time, on the date due; and funds received after that hour shall be deemed to have been received by GS on the following Business Day. Any amount due and payable under this Agreement which is not paid within the
period specified for the payment of such amount shall accrue interest thereon payable on demand and computed at the Overdue Rate. All payments shall be made by SAI without setoff, counterclaim or other defense. At any time that the Overdue Rate is
in effect, the two percent (2%) differential between the Interest Rate and the Overdue Rate must be paid to GS in cash regardless of whether GS is otherwise entitled under this Agreement to require SAI to make payment of the remainder of such
Overdue Rate interest in cash. 
 (b) Taxes. 

(i) Except where SAI is contesting in good faith and has established adequate reserves, SAI shall pay or cause to be paid
all present and future Taxes, duties, fees and other charges of whatsoever nature, if any, now or at any time hereafter levied or imposed by any Governmental Authority, by any department, agency, political subdivision or taxing or other authority

other amounts due under this Agreement and the Security Agreements shall be made without deduction for or on account of any such Taxes, duties, fees and other charges. 

  
 -14-

 (ii) In the event SAI is required to withhold any such amount or is
prevented by operation of law or otherwise from paying or causing to be paid such Taxes, duties, fees or other charges as aforesaid, the principal, interest or other amounts due under this Agreement and the Security Agreements (as the case may be)
shall be increased to such amount as shall be necessary to yield and remit to the payees the full amount such payees would have received (taking into account any such Taxes, duties, fees or other charges payable on amounts payable by SAI under this
Section had such payment been made without deduction of such Taxes, duties, fees or other charges (all and any of such additional amounts, herein referred to as the “Additional Amounts”). 

(iii) If this Section applies and GS so requires, SAI shall deliver to GS, official tax receipts evidencing payment (or
certified copies of them) of such Additional Amounts within thirty (30) days of the date of payment. 
 (iv)
SAI shall pay all Taxes (including, without limitation, stamp taxes), duties, fees or other charges payable on or in connection with the execution, issue, delivery, registration, notarization or enforcement of this Agreement (including translation
costs) and the Security Agreements and shall, upon notice from GS, reimburse Gs for any such Taxes, duties, fees or other charges paid by GS thereon. Notwithstanding the foregoing, for purposes of this section 2(b)(iv) the term “Taxes”
(i) does not include taxes imposed by the United States if GS is not incorporated under the laws of the United States or a state thereof unless GS (A) delivers to SAI within ten days after execution of this Agreement two copies of Internal

which GS may be entitled to an exemption from withholding or reduced rate of withholding unless GS takes whatever actions are required in order to qualify for such exemption or reduced withholding rate. If SAI shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder or such instrument, the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this
Section) GS will receive an amount equal on an After-Tax Basis to the sum it would have received had no such deductions been made, SAI shall make such deductions and SAI shall pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

called the “Guaranteed Obligations”). The Guarantor hereby agrees that if SAI shall fail to pay in full when due (whether upon maturity, by acceleration or otherwise) any of the
Guaranteed Obligations, the Guarantor will promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same will be promptly paid in
full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms of such extension or renewal. 
 4.2 The obligations of the Guarantor under this Guaranty are absolute, irrevocable and unconditional, irrespective of the value, genuineness, validity, regularity, avoidance, subordination or
enforceability of the obligations of SAI under this Agreement, or any other agreement or instrument referred to herein or therein, or any substitution, release or exchange of any other guarantee of or security for any of the Guaranteed Obligations,
and, to the fullest extent permitted by applicable law, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or Guarantor (except for payment in full). Without
limiting the generality of the foregoing, it is agreed that the occurrence of any one or more of the following shall not alter or impair the liability of the Guarantor hereunder which shall remain absolute, irrevocable and unconditional under any
and all circumstances as described above: (i) at any time or from time to time, without notice to the Guarantor, the time for any performance of or compliance with any of the Guaranteed Obligations shall be extended, or such performance or
compliance shall be waived; (ii) any of the acts mentioned in any of the provisions of this Agreement or any other agreement or instrument referred to herein or therein shall be done or omitted; (iii) the maturity of any of the Guaranteed
Obligations shall be accelerated, or any of the Guaranteed Obligations shall be amended in any respect, or any right under this Agreement, or any other agreement or instrument referred to herein or therein shall be amended or waived in any respect
or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or in part or otherwise dealt with; (iv) any lien or security interest granted to, or in favor of, GS or the Collateral
Agent as security for any of the Guaranteed Obligations shall fail to be perfected or shall fail to have the priority contemplated by the Security Agreements; (v) the consent, forbearance or granting of any indulgence by, or on behalf of GS
with respect to any provision of any of the Security Agreements; (vi) the election of any remedy available under the Security Agreements, or on behalf of, GS with respect to all or any part of the Guaranteed Obligations; (vii) the absence
of any attempt by, or on behalf of, GS to collect, or to take any other action to enforce, all or any part of the Guaranteed Obligations whether from or against SAI or any other Person; (viii) the election by, or on behalf of, GS, in any
proceeding instituted under Chapter 11 of the Bankruptcy Code with respect to SAI or the Guarantor, of the application of Section 1111(b)(2) of the Bankruptcy Code; (ix) any borrowing or grant of a security interest by SAI, as
debtor-in-possession, under Section 364 of the Bankruptcy Code; or (x) the disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of the claims against SAI held by any of GS, for repayment of all or any part of
the Guaranteed Obligations or any expenses. 
 4.3 The Guarantor hereby expressly waives diligence, presentment, demand of
payment, filing of claims with a court in the event of receivership or bankruptcy of SAI or any other Person (other than the Guarantor to the extent required by the Bankruptcy Code), protest and all notices whatsoever, and any requirement that GS or
Affiliate thereof exhaust any right, 

  
 -23-

 
power or remedy or proceed against SAI under this Agreement or any other agreement or instrument referred to herein or therein, or against any other Person under any other guarantee of, or
security for, any of the Guaranteed Obligations. The Guarantor waives any and all notice of the creation, renewal, extension, waiver, termination or accrual of any of the Guaranteed Obligations and notice of or proof of reliance by any SAI thereof
or GS upon this guarantee or acceptance of this guarantee, and the Guaranteed Obligations, and any of them, shall conclusively be deemed to have been created, contracted or incurred in reliance upon this guarantee, and all dealings between SAI and
GS thereof shall likewise be conclusively presumed to have been had or consummated in reliance upon this guarantee. This guarantee shall be construed as a continuing, absolute, irrevocable and unconditional guarantee of payment without regard to any
right of offset with respect to the Guaranteed Obligations at any time or from time to time held by GS thereof, and the obligations and liabilities of the Guarantor hereunder shall not be conditioned or contingent upon the pursuit by GS thereof or
any other Person at any time of any right or remedy against SAI or against any other Person which may be or become liable in respect of all or any part of the Guaranteed Obligations or against any collateral security or guarantee therefor or right
of offset with respect thereto. This guarantee shall remain in full force and effect and be binding in accordance with and to the extent of its terms upon the Guarantor and the successors and assigns thereof, and shall inure to the benefit of SAI,
and their successors and assigns, notwithstanding that from time to time during the term of this Agreement there may be no Guaranteed Obligations outstanding. 
 4.4 The obligations of the Guarantor under this Guaranty shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of SAI in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or reorganization or otherwise. The Guarantor agrees that it will indemnify GS thereof on
demand for all reasonable costs and expenses (including reasonable fees of counsel) incurred by GS thereof in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that
such payment constituted a preference, fraudulent transfer or similar payment under any bankruptcy, insolvency or similar law, other than any costs or expenses resulting from the gross negligence or bad faith of such Person. 

4.5 The Guarantor hereby agrees that until the indefeasible payment and satisfaction in full in cash of all Guaranteed Obligations it
shall not exercise any right or remedy arising by reason of any performance by it of its guarantee in Guaranty, whether by subrogation or otherwise, against SAI of any of the Guaranteed Obligations or any security for any of the Guaranteed
Obligations. The payment of any amounts due with respect to any indebtedness of SAI now or hereafter owing to any Guarantor by reason of any payment by such Guarantor under the guaranty in this Guaranty is hereby subordinated to the prior
indefeasible payment in full in cash of the Guaranteed Obligations. The Guarantor agrees that it will not demand, sue for or otherwise attempt to collect any such indebtedness of SAI to such Guarantor until the Obligations shall have been
indefeasibly paid in full in cash. If, notwithstanding the foregoing sentence, the Guarantor shall prior to the indefeasible payment in full in cash of the Guaranteed Obligations collect, enforce or receive, whether partial or complete, voluntary or
involuntary, and whether by reason of liquidation, bankruptcy, arrangement, receivership, assignment for the benefit of creditors or any other action or proceeding, or if the business of SAI is dissolved or if

  
 -24-

 
substantially all of the assets of SAI are sold, then, and in any such event, any payment or distribution of any kind or character, either in cash, securities or other property, any amounts in
respect of such indebtedness, such amounts shall be collected, enforced and received by the Guarantor as trustee for GS and be paid over to GS on account of the Guaranteed Obligations without affecting in any manner the liability of the Guarantor
under the other provisions of the guarantee contained herein. 
 4.6 The Guarantor agrees that, as between the Guarantor and GS,
the obligations of SAI under this Agreement may be declared to be forthwith due and payable upon an Event of Default for purposes of this Guaranty, notwithstanding any stay, injunction or other prohibition preventing such declaration (or such
obligations from becoming automatically due and payable) as against SAI and that, in the event of such declaration (or such obligations being deemed to have become automatically due and payable), such obligations (whether or not due and payable by
SAI) shall forthwith become due and payable by the Guarantor for purposes of this Guaranty. 
 4.7 The Guarantor hereby
acknowledges that the guarantee in this Guaranty constitutes an instrument for the payment of money, and consents and agrees that GS, at its sole option, in the event of a dispute by the Guarantor in the payment of any moneys due hereunder, shall
have the right to bring a motion-action under New York CPLR Section 3213. 
 4.8 The guarantee in this Guaranty is a
continuing guarantee, and shall apply to all Guaranteed Obligations whenever arising. 
 4.9 In any action or proceeding
involving any state corporate law, or any state, Federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of the Guarantor under this would otherwise be held or determined
to be void, voidable, invalid or unenforceable, or subordinated to the claims of any other creditors, on account of the amount of its liability under this , then, notwithstanding any other provision to the contrary, the amount of such liability
shall, without any further action by the Guarantor, GS or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not subordinated to the claims of other creditors as determined in such action
or proceeding. 
 4.10 GS is hereby authorized, without notice or demand and without affecting the liability of the Guarantor
hereunder, from time to time, (a) to otherwise renew, extend, accelerate or otherwise change the time for payment of, or other terms relating to, all or any part of the Guaranteed Obligations, or to otherwise modify, amend or change the terms
of any of this Agreement and the Security Agreements in accordance and pursuant to the terms of the relevant L/C Related Document under which the relevant Guaranteed Obligations arise; (b) to accept partial payments on all or any part of the
Guaranteed Obligations; (c) to take and hold security or collateral for the payment of all or any part of the Guaranteed Obligations, this guaranty, or any other guaranties of all or any part of the Guaranteed Obligations or other liabilities
of SAI, or any of them; (d) to exchange, enforce, waive and release any such security or collateral; (e) to apply such security or collateral and direct the order or manner of sale thereof as in its discretion it may determine; and
(f) to settle, release, exchange, enforce, waive, compromise or collect or otherwise liquidate all or any part of the Guaranteed Obligations, this Guaranty, any other guaranty of all or any part of the Guaranteed Obligations, and any security
or collateral for the 

  
 -25-

 
Guaranteed Obligations or for any such guaranty, irrespective of the effect on the contribution or subrogation rights of any Guarantor. Any of the foregoing may be done in any manner, without
affecting or impairing the obligations of the Guarantor hereunder. 
 4.11 Upon the occurrence and during the continuance of an
Event of Default, GS may proceed directly and at such times as GS may proceed against SAI pursuant to Section 8 of this Agreement, without notice, against the Guarantor to obtain performance of and to collect and recover the full amount, or any
portion, of the Guaranteed Obligations owing to such Persons, without first proceeding against SAI or any other Person, or against any security or collateral for the Guaranteed Obligations. Subject only to the terms and provisions of the Security
Agreements, GS shall have the exclusive right to determine the application of payments and credits, if any, from the Guarantor, SAI or any other Person, on account of the Guaranteed Obligations or any other liability of the Guarantor to GS.

 4.12 Guarantor hereby assumes responsibility for keeping itself informed of the financial condition of SAI and any and all
other endorsers of all or any part of the Guaranteed Obligations, and of all other circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations, or any part thereof, that diligent inquiry would reveal, and each Guarantor hereby
agrees that GS shall have no duty to advise any Guarantor of information known to it regarding such condition or any such circumstances. In the event GS, in its sole discretion, undertakes at any time or from time to time to provide any such
information to any Guarantor, such GS shall be under no obligation (i) to undertake any investigation not a part of its regular business routine, (ii) to disclose any information which such GS, pursuant to accepted or reasonable commercial
finance or banking practices, wishes to maintain confidential or (iii) to make any other or future disclosures of such information or any other information to any Guarantor. 

4.13 The Guarantor consents and agrees that none of GS or any Person acting for or on behalf of GS, shall be under any obligation to
marshal any assets in favor of the Guarantor or against or in payment of any or all of the Guaranteed Obligations. 
 4.14 No
delay on the part of GS in the exercise of any right or remedy arising under this guaranty, the and the Security Agreements or otherwise with respect to all or any part of the Guaranteed Obligations, the Collateral or any other guaranty of or
security for all or any part of the Guaranteed Obligations shall operate as a waiver thereof, and no single or partial exercise by GS of any such right or remedy shall preclude any further exercise thereof. No modification or waiver of any of the
provisions of this guaranty shall be binding upon GS or the Collateral Agent, except as expressly set forth in a writing duly signed and delivered by the Collateral Agent and GS. Failure by GS at any time or times hereafter to require strict
performance by SAI, any other guarantor of all or any part of the Guaranteed Obligations or any other Person of any of the provisions, warranties, terms and conditions contained in any of this Agreement and the Security Agreements now or at any time
or times hereafter executed by such Persons and delivered to GS shall not waive, affect or diminish any right of GS at any time or times hereafter to demand strict performance thereof and such right shall not be deemed to have been waived by any act
or knowledge of GS (or their respective agents, officers or employees), unless such waiver is contained in an instrument in writing, directed and delivered to SAI or the 

  
 -26-

 
Guarantor, as applicable, specifying such waiver, and is signed by GS. No waiver of any Event of Default by GS shall operate as a waiver of any other Event of Default or the same Event of Default
on a future occasion, and no action by GS permitted hereunder shall in any way affect or impair GS’s rights and remedies or the obligations of the Guarantor under this Guaranty. Any determination by a court of competent jurisdiction of the
amount of any principal and/or interest owing by SAI to GS shall be conclusive and binding on the Guarantor irrespective of whether the Guarantor was a party to the suit or action in which such determination was made. 

4.15 Substantially concurrently herewith, Guarantor has executed and delivered the Security Agreements and the Collateral Agency,
Subordination and Intercreditor Agreement to secure the Guarantor’s obligations under this Guaranty. 
 4.16 GS agrees that
upon (i) any disposition by SAI of 100% of its equity interests in Guarantor to any non-affiliated Person for fair value in all respects pursuant to Section 6.3 hereof, and (ii) the delivery to the Collateral Agent of the net
proceeds, if any, of any such transaction to be held as additional collateral for the Obligations then GS will immediately release its liens on the assets of Guarantor and terminate the Guarantor’s obligations under this Section 4, and
further agrees to execute and deliver to Guarantor reasonable and customary documentation effecting the same, at Guarantor’s reasonable expense.

the Reserve Account at any time that SAI Reserve Cash is less than $20,000,000 or after such distribution would be less than $20,000,000. As a condition to the effectiveness of one or more Covenant Event of Default Waivers pursuant to

amount of SAI Reserve Cash.

8.2 Covenant Events of Default.

Default has occurred and is continuing, GS shall forbear from (i) giving a Control Notice (defined below) or (ii) exercising 

  
 -37-

 
any of its rights and remedies set forth in Section 8 as a result of such Covenant Event of Default for sixty (60) days following the occurrence of such Covenant Event of Default (a
“Covenant Forbearance Period”). During any Covenant Forbearance Period, one or more of the Noteholders which, in the aggregate, constitute Requisite Lenders, shall have the option but not the obligation to exercise all of the rights of
Requisite Creditors under the Collateral Agency, Subordination and Intercreditor Agreement, and to take all the actions permitted pursuant to Section 8.2(b) below.

Period for such Covenant Event of Default has not expired, (iii) giving effect to the waiver being requested hereunder, SAI is then in compliance with Section 5.6 and (iv) all equivalent “Events of Default” under the Senior
Subordinated Indebtedness have been waived on the same terms and conditions, then any one or more of the Noteholders which, in the aggregate, constitute a majority in interest of the Noteholders may notify GS in writing that such Noteholders have
agreed to waive the occurrence and continuance of the specific events or conditions giving rise to such Covenant Event(s) of Default and all equivalent “Events of Default” under the Senior Subordinated Indebtedness have been waived on the
same terms and conditions, the occurrence and continuance of the specific conditions giving rise to such Covenant Event of Default shall be deemed permanently waived by GS for all purposes of this Agreement, SAI and the Guarantor shall be deemed to
be in full compliance with the terms of this Agreement, and GS shall thereupon have no right or authority to (i) give a Control Notice under the Collateral Agency, Subordination and Intercreditor Agreement (a “Control Notice”) or
(ii) exercise any of its rights and remedies set forth in Section 8 as a result of such waived Covenant Event of Default (but without prejudice to the right of GS to give a Control Notice with respect to any subsequent occurrence of a
Covenant Event of Default of the same type). For avoidance of doubt, so long as Servicers are in compliance with Section 5.6, SAI may receive additional waivers of Covenant Events of Default without need for further deposit. 

8.3 Bankruptcy Forbearance Period. 
 (a) Provided that (i) no Event of Default under Section 8.1(a) or 8.1(b) has occurred and is continuing and (ii) within 5 Business Days after the commencement of a proceeding in Chapter 11
of the Bankruptcy Law SAI is in compliance with Section 5.6(a) of this Agreement, GS shall forbear from giving a Control Notice with respect to a Bankruptcy Event of Default or from exercising any of its rights and remedies set forth in
Section 8 as a result of such Bankruptcy Event of Default for a period of One Hundred Twenty (120) days following the occurrence of such Bankruptcy Event of Default, provided that if a plan of reorganization is filed for SAI during such
120 period such forbearance shall continue until such filed plan of reorganization is confirmed or rejected by the applicable bankruptcy court (the “Bankruptcy Forbearance Period”). For avoidance of doubt, so long as SAI is in compliance
with Section 5.6, the requirement hereunder will be thereby satisfied with respect to the Bankruptcy Event of Default without need for further deposit. 
 (b) Any Bankruptcy Forbearance Period any time in effect shall terminate, and GS shall be entitled to give a Control Notice with respect to such Bankruptcy Event of Default and/or exercise any of its
rights and remedies set forth in Section 8 as a result of such Bankruptcy Event of Default upon the occurrence of any of the following: (i) any secured 

  
 -38-

 
creditor of SAI (other than the Senior Subordinated Creditors if proceeding in accordance with the terms of a filed plan of reorganization) obtains a modification of the automatic stay and
commences a foreclosure action under state law with respect to such secured creditor’s collateral provided that in case of any foreclosure by the Collateral Agent pursuant to Liens that are subject to the Collateral Agency, Subordination and
Intercreditor Agreement, the proceeds of such foreclosure shall by applied by the Collateral Agent pursuant to Section 3.07 of the Collateral Agency, Subordination and Intercreditor Agreement; (ii) SAI ceases flight operations for more
than seven (7) consecutive days for any reason; (iii) GS does not receive in cash and on time any portion of the Commitment Fee that must be paid in immediately available funds pursuant to Section 2.2(a) of this Agreement; or
(iv) SAI’s bankruptcy case has been converted to a case under Chapter 7 of the Bankruptcy Law. 
 8.4 Remedies.
If an Event of Default shall have occurred and be continuing, but subject to the forbearance and waiver provisions of Sections 8.2 and 8.3, GS may immediately give the Collateral Agent and the Senior Subordinated Creditors a Control Notice with
respect to such Covenant Event of Default and shall be authorized to (a) exercise all powers of Requisite Creditors as provided therein, and /or (b) declare all or any part of the Obligations to be due and payable and/or (c) demand
that Obligations be Paid in Full, whereupon the making of such demand SAI shall be required to cause the Obligations to be Paid in Full, all without presentment, demand, protest or notice of any kind. GS shall promptly advise SAI of any such
declaration, but failure to do so shall not impair the effect of such declaration. Any cash collateral delivered hereunder shall be held by GS (without liability for interest thereon) and applied to Reimbursement Claims. After the expiration or
termination of the Letter of Credit, if any, any cash collateral provided with respect to the Letter of Credit shall be applied by GS to any remaining Obligations hereunder and any excess shall be delivered to SAI or as a court of competent
jurisdiction may direct. In addition, so long as all Obligations shall not have been Paid in Full, GS may direct the Collateral Agent to exercise any rights and remedies available under the Security Agreements and GS may exercise such other rights
and remedies available to it under applicable law. Nothing contained in this Section 8.4 shall be interpreted or construed as precluding GS from giving a Control Notice with respect to any Event of Default that is neither waived pursuant to
Section 8.2 nor subject to a Covenant Forbearance Period or a Bankruptcy Forbearance Period.

YORK AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE. SAI FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL, POSTAGE PREPAID, OR BY
PERSONAL SERVICE WITHIN OR WITHOUT THE STATE OF NEW YORK. SAI HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN
ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM.

the specification of Dollars is of the essence, and Dollars shall be the currency of account in the case of all obligations under this Agreement. The payment obligations of SAI and the Guarantor under this Agreement shall not be discharged by an
amount paid in a currency or in a 

  
 -42-

 
place other than that specified with respect to such obligations, whether pursuant to a judgment or otherwise, to the extent that the amount so paid on prompt conversion to Dollars and transfer
to the specified place of payment under normal banking procedures does not yield the amount of Dollars, in such place, due under this Agreement. In the event that any payment, whether pursuant to a judgment or otherwise, upon conversion and transfer
does not result in payment of such amount of Dollars in the specified place of payment, the obligee of such payment shall have a separate cause of action against the party making the same for the additional amount necessary to yield the amount due
and owing under this Agreement. If, for the purpose of obtaining a judgment in any court with respect to any obligation of SAI under this Agreement or any of the agreements contemplated hereby, it shall be necessary to convert to any other currency
any amount in Dollars due thereunder and a change shall occur between the rate of exchange applied in making such conversion and the rate of exchange prevailing on the date of payment of such judgment, the judgment debtor agrees to pay such
additional amounts (if any) as may be necessary to insure that the amount paid on the date of payment is the amount in such other currency which, when converted into Dollars and transferred to New York, New York, in accordance with normal banking
procedures, will result in the amount then due under this Agreement or such agreements in Dollars. Any amount due from the judgment debtor shall be due as a separate debt and shall not be affected by or merged into any judgment being obtained for
any other sum due under or in respect of this Agreement or any of the agreements contemplated hereby. In no event, however, shall the judgment debtor be required to pay a larger amount in such other currency at the rate of exchange in effect on the
date of payment than the amount of Dollars stated to be due under this Agreement or any of the agreements contemplated hereby, so that in any event the obligations of the judgment debtor under this Agreement will be effectively maintained as Dollar
obligations. 
 9.17 Indemnification. SAI agrees, and agrees to cause each of its Subsidiaries, (i) to indemnify
each Indemnified Party (as hereinafter defined), upon demand, from and against any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including
reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called “liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or
asserted against such Indemnified Party arising out of or resulting from or in any other way associated with (x) any of this Agreement or the Security Agreements or any transaction contemplated thereby or (y) this Agreement or any of the
transactions and events (including the enforcement or defense thereof) at any time associated herewith or contemplated herein (including, but not limited to, any violation or noncompliance with, or any liability or duty under, any Environmental Laws
by any related party thereof or any liabilities or duties of any related party thereof or of any Indemnified Party arising out of any actual or alleged presence or release of Hazardous Materials on or from any property currently or formerly owned or
operated by SAI, Guarantor, or any Subsidiary); and (ii) to reimburse each Indemnified Party, upon demand, for its reasonable legal and other reasonable expenses as they are incurred in connection with the foregoing. THE FOREGOING
INDEMNIFICATION AND REIMBURSEMENT SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY OR ARE IN ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY 

  
 -43-

 
ANY INDEMNIFIED PARTY, provided only that no Indemnified Party shall be entitled under this section to receive indemnification or reimbursement for that portion, if any, of any
liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment. As used in this section, the term “Indemnified Party” refers to GS (including any of its

 “(c)
In the event that SAI and the Servicer agree that that the Required Amount (as defined in the Bankcard Agreement) may be less than 100% of Gross Exposure and such agreement results in the Servicer releasing a portion of the Deposit, then 50% of such
released funds shall be remitted to GS to be held as Cash Collateral and 50% of such released funds shall be remitted to SAI; provided that (i) the Required Amount shall be no less than 85% of Gross Exposure and (ii) no such funds shall be

 Exhibit 10.1 
 CHANGE IN CONTROL BONUS AGREEMENT 
 THIS CHANGE IN CONTROL BONUS AGREEMENT
(this “Agreement”) is made as of April 29, 2011 (the “Effective Date”), between Integral Systems, Inc., a Maryland corporation (the “Company”), and Paul G. Casner, Jr.
(“Executive”). 
 R E C I T A L S 

WHEREAS, Executive is the Chief Executive Officer of the Company; and 

WHEREAS, the Company considers the continued availability of Executive’s services, managerial skills and business experience to be
in the best interest of the Company and its stockholders and desires to assure the continued services of Executive on behalf of the Company without the distraction of Executive occasioned by the possibility of a Change in Control of the Company; and

 NOW THEREFORE, in consideration of the mutual covenants set forth herein, and for other good and valuable consideration,
receipt of which is hereby acknowledged, the parties, intending to be legally bound, do hereby agree as follows: 
 AGREEMENTS

 1. Change in Control Bonus. Subject to Executive’s continued employment with the Company through the
occurrence of the first Change in Control that occurs no later than April 1, 2013, the Company shall pay Executive a lump sum cash payment of $1 million (the “Change in Control Bonus”) within five (5) days following such
Change in Control. The Change in Control Bonus shall be subject to all applicable tax and other legally-required withholdings. 
 For purposes
hereof, “Change in Control” means the occurrence of any of the following: 
  

	 	(a)	Any person or group (within the meaning of Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), other
than the Company or a trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their
ownership of stock of the Company, becomes the beneficial owner (within the meaning of Rule 13(d)(3) under the Exchange Act), directly or indirectly, of securities representing more than 50% of the combined voting power of the Company’s
then-outstanding securities entitled generally to vote for the election of directors; 

  

	 	(b)	The Company merges or consolidates with another corporation (other than a majority-controlled subsidiary of the Company) unless the Company’s stockholders
immediately before the merger or consolidation are to own at least 50% of the combined voting power of the resulting entity’s voting securities entitled generally to vote for the election of directors; 

 

	 	(c)	The Company sells or otherwise disposes of all or substantially all of the business or assets of the Company; or 

	 	(d)	Individuals who, as of the Effective Date, constitute the members of the board of directors of the Company (the “Incumbent Board”) cease for any reason
to constitute at least a majority of the board of directors of the Company (the “Board”), provided that any person becoming a director subsequent to the Effective Date whose election or nomination for election by the Company’s
stockholders is approved by a vote of at least a majority of directors then constituting the Incumbent Board (either by a specific vote or by approval of the proxy statement of the Company in which such person is named as a nominee for direction,
without objection to such nomination) shall be, for purposes of this Agreement, considered as though such person were a member of the Incumbent Board (excluding, however, for this purpose any Board member whose initial assumption as a member of the
Board occurs as a result of either an actual or threatened election contest or other actual or threatened solicitation of proxies or consents by or on behalf of any person or persons other than the Incumbent Board). 

However, no Change in Control shall be deemed to have occurred by a reason of (A) any event involving a transaction in which Executive or a group of
persons or entities with whom or with which Executive acts in concert, acquire(s), directly or indirectly, more than 50% of the combined voting power of the Company’s then-outstanding voting securities or the business or assets of the Company;
or (B) any event involving or arising out of a proceeding under Title 11 of the United States Code or the provisions of any future United States bankruptcy law, an assignment for the benefit of creditors or an insolvency proceeding under state
or local law. 
 A Change in Control shall be deemed to occur, (I) with respect to a Change in Control pursuant to subparagraph
(i) above, on the date any person or group first becomes the beneficial owner, directly or indirectly, of securities representing more than 50% of the combined voting power of the Company’s then-outstanding securities entitled generally to
vote for the election of directors, (II) with respect to a Change in Control pursuant to subparagraph (ii) or (iii) above, on the date the applicable transaction closes, or (III) with respect to a Change in Control pursuant to subparagraph
(iv) above, on the date members of the Incumbent Board first cease to constitute at least a majority of Board. 
 2.
Golden Parachute Cutback. If Executive’s receipt of compensation or benefits under the terms of Section 1 hereof and otherwise would cause Executive to become subject to the excise tax imposed under Section 4999 of the Internal
Revenue Code of 1986, as amended (the “Code”), the Change in Control Bonus shall be reduced to the extent necessary to avoid the application of such excise tax. If requested by Executive, the determination of whether Executive would
be subject to the excise tax imposed under Section 4999 of the Code, and the calculation of the amount of any reduction, shall be made, at the Company’s discretion, by the Company’s outside auditing firm or by a nationally-recognized
accounting or benefits consulting firm designated by the Company prior to a Change in Control. Such firm’s expenses shall be paid by the Company. 
 3. Not an Employment Contract. Nothing in this Agreement or any other instrument executed pursuant hereto shall confer upon Executive any right to continue in the employ of the Company or shall
affect the right of the Company to terminate the employment of Executive with or without cause. 

  
 2 

 4. Governing Law. All terms of and rights under this Agreement shall be governed by
and construed in accordance with the internal laws of the State of Maryland, without giving effect to principles of conflicts of law. 
 5. Amendments and Waivers. This Agreement may be amended, and any provision hereof may be waived, only by a writing signed by each party hereto. 

6. Entire Agreement. This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter
hereof and supersedes all prior oral and written and all contemporaneous oral discussions, agreements and understandings of any kind or nature. 
 7. Separability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of
this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the maximum extent possible. 
 8. Headings. The headings preceding the
text of the sections hereof are inserted solely for convenience of reference, and shall not constitute a part of this Agreement, nor shall they affect its meaning, construction or effect. 

9. Counterparts. This Agreement may be executed in two counterparts, each of which shall be deemed an original, but which together
shall constitute one and the same instrument. 
 10. Assignment; Binding Effect. This Agreement may not be assigned by
Executive without the prior written consent of the Company. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective permitted successors and assigns. 

IN WITNESS WHEREOF, the parties have executed this Agreement as of the date first written above.
