 – 23 – 








 
of such Retired MD-80 Charges exceeds the sum of (i) for each completed fiscal period set forth on Schedule 1, the amount set forth for such fiscal period on Schedule 1 under the heading
“Target Points”, plus (ii) for the fiscal period in effect when the Trigger Event occurs, an amount equal to the product of (A) the amount set forth for such fiscal period on Schedule 1 under the heading “Target
Points”, and (B) a fraction, the numerator of which is the actual number of days elapsed in such fiscal period prior to the occurrence of the Trigger Event and the denominator of which is the total number of days in such fiscal period (the
sum of clauses (i) and (ii) being the “Charge Threshold”), then, promptly following the occurrence of such Trigger Event, the aggregate liquidation preference of the Class A Preferred Stock shall automatically be
reduced by the amount that such Retired MD-80 Charges actually incurred as of date of the Trigger Event exceeds the Charge Threshold, provided, that in no event will the aggregate liquidation preference of the Class A Preferred Stock be
reduced by more than $30,000,000 as a result of this Section 2.7(b). For the avoidance of doubt, no accrued and unpaid dividends shall be paid in respect of the portion of the liquidation preference that is so eliminated in accordance

Bankruptcy Event or Qualified Recapitalization shall have occurred prior to January 1, 2008 and (ii) at any time prior to the consummation of any of the foregoing events, the Actual Block Cost per Hour exceeded $345, the aggregate
liquidation preference of the Class A Preferred Stock shall automatically be reduced by $22,500,000, with respect to (x) or (y), effective January 1, 2008, and, with respect to (z), effective upon the consummation of such Sale of the
Company, Initial Public Offering, Bankruptcy Event or Qualified Recapitalization, and no accrued and unpaid dividends shall be paid in respect of the portion of the liquidation preference that has been so eliminated. The determinations made pursuant
to (y)(ii) and (y)(iii) above shall be made on or about January 1, 2008 and based on the Issuer’s operating plan for 2008 as approved by the Board of Directors. 

SECTION 3 

TERMS OF THE NOTES 

Section 3.1 Rate of Interest; Payment of Interest. 

(a) Except as set forth in Section 3.1(b) or as otherwise set forth in the Notes executed and delivered by the Issuer,
during the period from the date of issuance to and including the date of their repayment in full, the Notes shall bear and accrue interest on the unpaid principal amount from time to time outstanding at the rate of seventeen percent (17%) per
annum accruing on a daily basis compounded annually on each Annual Payment Date to the extent not paid. Interest on the Notes may be payable in arrears in cash or deemed paid when added to the principal amount of the Notes, in either case, on each
Annual Payment Date, and at the sole discretion of the Board of Directors. All interest that has accrued and is not paid in cash on any Annual Payment Date shall be added to the principal amount of the applicable Note as of the applicable Annual
Payment Date (and following such addition such accrued interest shall no longer be deemed to be accrued and unpaid). 
  

 – 24 – 








 (b) Commencing on the Initial Closing Date, no interest shall accrue on the outstanding
principal balance due under the Tranche A Notes until January 27, 2007 (such interest free period being the “ Tranche A Interest Holiday”). On January 28, 2007, interest accrual on the outstanding principal balance due
under the Tranche A Notes shall recommence and shall thereafter continue pursuant to the terms thereof and of this Agreement. For avoidance of doubt, (i) in any calculation of accrued interest or principal after capitalization of accrued

Section 3.2 Computation of Interest. Subject to Section 3.1(b), Interest shall be computed on the Notes on the
basis of a 360-day year and the actual number of days elapsed. On each Annual Payment Date, Interest on the Notes shall be computed as the sum of the daily interest for the period prior to each Payment Date, taking into account the outstanding
principal balance of the Notes on each day of the period (where such balance on any given day shall reflect any payment of principal credited on such date pursuant to Section 3.7 hereof). 

Section 3.3 Payment of Principal. The outstanding principal balance of the Notes shall be due and payable in full on
the Maturity Date to the extent not prepaid pursuant to Section 3.4 or 8.1(b) prior thereto. 

Section 3.4 Optional Prepayments of the Notes. The Issuer may prepay the Notes, at its option, in accordance with the

shall be made ratably as to each Holder based on each Holder’s Pro Rata Portion of the aggregate amount of such Prepayment. 

Section 3.6 General Payment Provision. 

(a) Except as may be agreed by the Holders, the Issuer shall make each payment which the Issuer owes under this Agreement and any of
the other Transaction Documents not later than 2:00 p.m., New York, New York time, on the date such payment becomes due and payable, without set-off, deduction or counterclaim, in lawful money of the United States of America, in immediately

specific place of payment is provided, shall be due and payable at the place of payment of the Notes.

or principal payment from or on behalf of the Issuer, shall be applied as follows in descending order of priority: 

(i) to all costs and expenses (including reasonable attorneys’ fees) payable pursuant to
Section 9.15 hereof or in enforcing any Note Obligations of, or in collecting any payments from, any obligor hereunder or under the other Transaction Documents;

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”).

connection with the sale of assets, in which case the Tranche B Requisite Holders and, to the extent that Holdings II is entitled to consent to the transfer of such assets pursuant to Section 8E(i) of the Investor Rights Agreement, the Tranche
A Requisite Holders, shall provide the requisite instruction to the Collateral Agent). 
 (iv) The remedies
provided for herein are cumulative and are not exclusive of any remedies that may be available to the Holders at law or in equity or otherwise.

representative thereof, and no such representation or covenant has been made, that such Purchaser will, at the time of an Event of Default or Default or breach, or at any other time, waive,
negotiate, discuss, or take or refrain from taking any action permitted under the Transaction Documents with respect to any such Event of Default or Default or breach or any other provision of the Transaction Documents; 

(viii) the obligations of the Holders are several, not joint and several, and no Holder shall be liable for any act
or omission by another Holder; and

Purchasers, Holdings II, Holdings III, Holdings III-A and their respective Affiliates may review the business plans and related proprietary information of many enterprises, including enterprises which may have products or services which compete

participating in any particular enterprise, or trading in the securities thereof, whether or not such enterprise has products or services that compete with those of the Issuer or any of its Subsidiaries. Except as the Indigo Purchasers, Holdings II,
Holdings III, Holdings III-A and their respective Affiliates may otherwise agree in writing after the date hereof with respect to itself or its Affiliates (or its or its Affiliates’ employees, officers, directors, partners, members,
stockholders, or agents): (i) such Persons shall have the right to, and shall have no duty (contractual or otherwise) not to, directly or indirectly: (A) engage in the same or similar business activities or lines of business as the Issuer
or any of its Subsidiaries and (B) do business with any client or customer of the Issuer or any of its Subsidiaries; (ii) no such Person shall be liable to the Issuer or any of its Subsidiaries or stockholders for breach of any duty
(contractual or otherwise) by reason of any such activities or of such Person’s participation therein; and (iii) in the event that any such Person acquires knowledge of a potential transaction or matter that may be a corporate opportunity
for the Issuer or its Subsidiaries on the one hand, and any such Person on the other hand, or any other person, no such Person shall have any duty (contractual or otherwise) to communicate or present such corporate opportunity to the Issuer or any
of its Subsidiaries or any of its stockholders and, notwithstanding any provision of this Agreement to the contrary, such Persons shall not be liable to the Issuer or its Subsidiaries or Shareholders for breach of any duty (contractual or otherwise)
by reason of the fact that any such Person directly or indirectly pursues or acquires such opportunity for itself, directs such opportunity to another person, or does not present such opportunity to the Issuer or its Subsidiaries or stockholders.

 – 66 – 








 
Guarantor in the Transaction Documents, and the rights, powers and privileges granted to the Holders in the Transaction Documents, are cumulative, and, except for expressly specified waivers and
consents, no Transaction Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to the Holders of any such representation, warranty, covenant, right, power or privilege. In particular and without
limitation, no exception set out in this Agreement to any representation, warranty or covenant herein contained shall apply to any similar representation, warranty or covenant contained in any other Transaction Document, and each such similar

(a) The Holders, the Issuer, the Guarantor and any other parties to the Transaction Documents intend to contract in strict compliance
with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Transaction Documents shall ever be construed to create a contract to pay, for the
use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. Neither the Issuer nor the Guarantor nor any present or future guarantors, endorsers,
or other Persons hereafter becoming liable for payment of any Note Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under
applicable law from time to time in effect, and the provisions of this Section shall control over all other provisions of the Transaction Documents which may be in conflict or apparent conflict herewith. 

(b) The Holders expressly disavow any intention to contract for, charge or collect unearned interest or finance charges in the event
the maturity of any Note Obligation is accelerated. If (i) the maturity of any Note Obligation is accelerated for any reason, (ii) any Note Obligation is prepaid and as a result any amounts held to constitute interest are determined to be
in excess of the legal maximum, or (iii) the Holders or any other holder of any or all of the Note Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all
of the obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all such sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the
then-outstanding principal of the related Note Obligations or, at the Holders’ option, promptly returned to Issuer or the other payor thereof upon such determination. 

(c) In determining whether or not the interest paid or payable under any specific circumstances exceeds the maximum amount permitted
under applicable law, the Holders and the Related Parties thereof (and any other payors thereof) shall, to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than
as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Note
Obligations in accordance with the amounts outstanding from time to time thereunder and the Highest Lawful Rate from time to time in effect under applicable law in order to lawfully charge the maximum amount of interest permitted under applicable
law. 
 Section 9.7 Termination; Limited Survival. Issuer may, in its sole and absolute discretion at any time
that no Note Obligation is owing under the Transaction Documents, elect in a notice delivered to the Holders to terminate this Agreement. Upon receipt by the Holders of such a notice, if no such Note Obligation is then owing, then this Agreement and
all other Transaction Documents shall thereupon be terminated, and the parties thereto released from all prospective obligations thereunder; provided further, that any obligations hereunder in favor of the Holders of any Securities
(other than the Notes) shall survive such termination. Notwithstanding the foregoing or anything herein to the contrary, any representation or warranty made by the Issuer or any of its Subsidiaries to the Holders herein,

  

 – 69 – 








 
any waivers or admissions made by Issuer in any Transaction Document and any obligations which any Person may have to indemnify or compensate the Holders shall survive any termination of this
Agreement or any other Transaction Document. At Issuer’s request and expense, the Holders shall prepare and execute all necessary instruments to reflect and effect such termination of the Transaction Documents. All representations and
warranties and covenants made herein by the Issuer or the Guarantor or in any certificate or other instrument delivered by it or on its behalf under this Agreement shall be considered to have been relied upon by Purchaser and shall survive the
issuance of the Securities regardless of any investigation made by or on behalf of Purchaser. 

Section 9.8 Exchange or Substitution of Securities. 

(a) Registration of Securities. Issuer shall keep at its principal executive office a register for the registration and
registration of transfers of the Securities (the “Register”). The name and address of each Holder, each transfer thereof and the name and address of each transferee of one or more Securities shall be registered in such Register.
Prior to due presentment for registration of transfer, the Person in whose name any Security shall be registered shall be deemed and treated as the owner and Holder thereof for all purposes hereof, and Issuer shall not be affected by any notice or
knowledge to the contrary. Issuer shall give to any Holder, promptly upon request therefor, a complete and correct copy of the names and addresses of all registered Holders of Securities. 

(b) Replacement of Securities. Upon receipt by Issuer of evidence reasonably satisfactory to it of the ownership of and the
loss, theft, destruction or mutilation of any Security, and (i) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the Holder of such Security is, or is a nominee for, a Purchaser,
such Person’s own unsecured agreement of indemnity shall be deemed to be satisfactory), or (ii) in the case of mutilation, upon surrender and cancellation thereof, Issuer at its own expense shall execute and deliver, in lieu thereof, a new
Security of the same series, dated and, in the case of a Note, bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Security or dated the date of such lost, stolen, destroyed or mutilated
Security if no interest shall have been paid thereon. 
 Section 9.9 Waiver of Jury Trial, Punitive Damages,
Etc. ISSUER, FOR ITSELF AND EACH OF ITS SUBSIDIARIES, AND THE HOLDERS HEREBY: 
 (a) KNOWINGLY, VOLUNTARILY,
INTENTIONALLY, AND IRREVOCABLY WAIVE, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH
THE TRANSACTION DOCUMENTS OR THE PURCHASE AND SALE OF ANY SECURITIES CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY; 

(b) CERTIFY THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS

  

 – 70 – 








 
REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS; AND 

(c) ACKNOWLEDGE THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS AND THE TRANSACTIONS
CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION. 

Section 9.10 Exhibits and Schedules; Additional Definitions. All Exhibits and Schedules to this Agreement are a part
hereof for all purposes. 
 Section 9.11 Confidentiality of Holders. 

(a) Each Holder agrees, severally and not jointly, to use the same degree of care as such Holder uses to protect its own confidential
information to keep confidential any information furnished to it which the Issuer identifies in writing as being proprietary or confidential (the “Issuer Confidential Information”), except such information that (a) was in the
public domain prior to the time it was furnished to such Holder, (b) is or becomes (through no willful or improper action or inaction by such Holder) generally available to the public, (c) was in its possession or known by such Holder
without restriction prior to receipt from the Issuer, (d) was rightfully disclosed to such Holder by a third party without restriction or (e) was independently developed without any use of the Issuer’s confidential information.
Notwithstanding the foregoing, each Holder may disclose such proprietary or confidential information to any former partner who has retained an economic interest in such Holder, current or prospective partner, limited partner, general partner or
management company of such Holder (or any employee or representative of any of the foregoing) (each of the foregoing persons, a “Permitted Disclosee”) or legal counsel, accountants or representatives for such Holder or Permitted
Disclosee; provided, however, that any such Permitted Disclosee to whom Issuer confidential information is disclosed shall be subject to the confidentiality provisions of the operating agreements of such Holder. Furthermore, nothing contained herein
shall prevent any Holder or Permitted Disclosee from (a) entering into any business, entering into any agreement with a third party, or investing in or engaging in investment discussions with any other company (whether or not competitive with
the Issuer), provided that such Holder or Permitted Disclosee does not, except as permitted in accordance with this Section 9.11, disclose any proprietary or confidential information of the Issuer in connection with such activities, or
(b) making any disclosures required by law, rule, regulation or court or other governmental order. 
 (b) Subject to
Section 9.11(c), each of the Holders may disclose Issuer Confidential Information to its respective directors, officers, members, partners, employees, and agents (including attorneys, accountants, and consultants) to whom such disclosure
is reasonably necessary for the execution or effectuation hereof, provided such Holder notifies the Issuer that the Issuer Confidential Information disclosed to them is subject to this section and requires them not to disclose or use such
information in breach of this Section. Subject to Section 9.11(c), each Holder may also disclose Issuer Confidential Information to (i) any other Holder of any Securities, (ii) any Person to which it sells or offers to sell
such Securities or any part thereof or 
  

 – 71 – 








 
any participation therein (if such Person has agreed in writing prior to its receipt of such Issuer Confidential Information to be bound by the provisions of this Section 9.11),
(iii) any federal or state regulatory authority having jurisdiction over it, or (iv) to effect compliance with any law, rule, regulation or order applicable to it, (v) in response to any subpoena or other legal process, (vi) in
connection with any litigation to which it is a party or (vi) if an Event of Default has occurred and is continuing, to the extent it may reasonably determine such delivery and disclosure to be necessary or appropriate in the enforcement or for
the protection of the rights and remedies under the Transaction Documents. 
 (c) If any Holder is requested or required by
legal process (including law or regulation, oral questions, interrogatories, request for information or documents, subpoena, and civil investigative demand) to disclose any Issuer Confidential Information, if and to the extent legally permitted to
do so, such Holder shall promptly notify the Issuer of such request prior to complying with such process so that the Issuer may seek an appropriate protective order or waive the respondent’s compliance with this Section. If, after such notice
and after providing the Issuer a reasonable opportunity to obtain a protective order or to grant such waiver (so long as the granting of such time does not put such Holder in breach of its obligations to disclose), such Holder is nonetheless legally
compelled to disclose such information, such Holder may do so without liability under this Section. 
 (d) Any Issuer
Confidential Information which becomes publicly available through no breach by the relevant party hereunder or a breach by a third party of a confidential obligation to the relevant party hereunder shall no longer be deemed to be Issuer Confidential
Information. 
 (e) It is further understood and agreed that money damages would not be sufficient remedy for any breach of
the obligations of this Section 9.11 and that Issuer may be entitled to specific performance, including, without limitation, injunctive relief, as a remedy for any such breach. Such remedy shall not be deemed to be the exclusive remedy
for breach hereunder but shall be in addition to all other remedies available at law or equity. 

Section 9.12 Delivery of Documents by Facsimile. Delivery of an executed counterpart of this Agreement or of any other
documents in connection with this Agreement or the Transaction Documents (except any Notes or stock certificates) by facsimile will be deemed as effective delivery of an originally executed counterpart. 

Section 9.13 Successors and Assigns. Except as otherwise expressly provided herein, this Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the parties (including any Purchaser or subsequent Holder) whether so expressed or not. 

Section 9.14 Counterparts. Two or more duplicate originals of this Agreement may be signed by the parties, each of
which shall be an original but all of which together shall constitute one and the same instrument. 

Section 9.15 Severability. In the event that any one or more of the provisions contained herein, or the application
thereof in any circumstance, is held invalid, 
  

 – 72 – 








 
illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or impaired
thereby. 
 Section 9.16 Expenses. The Issuer shall pay all reasonable costs and expenses incurred by the
Purchasers or any Holder (a) relating to the negotiation, preparation, execution and delivery of this Agreement and the other Transaction Documents and the issuance of the Securities (including, without limitation, reasonable fees, office
charges and expenses of counsel to the Purchasers), (b) relating to printing the instruments evidencing the Securities, (c) relating to any amendments, waivers or consents (whether or not executed) under this Agreement to the same extent
as set forth in clause (a) and (b) above, (d) relating to the filing, recording, refiling and re-recording of any Transaction Document and any other documents or instruments or further assurances required to be filed or recorded or
refiled or re-recorded by the terms of any Transaction Document, or any other event with respect to which Issuer shall have the right to recover from any party expenses or costs paid or reimbursed to Holders, (e) incident to the enforcement by
the Holders of, or the protection or preservation of any right or remedy of the Holders under, this Agreement, the other Transaction Documents or any other document or agreement furnished pursuant hereto or thereto or in connection herewith or
therewith (including, without limitation, reasonable fees and expenses of counsel) and (f) relating to any bankruptcy, insolvency or other similar action or proceeding in any jurisdiction involving the Issuer. The Issuer’s obligations
under this Section 9.16 shall survive the payment of the Notes. In no event shall any waiver of the provisions set forth in Section 6.2(c) with respect to any Closing Date be deemed a waiver of the payment of the fees, costs
and expenses required to be paid by the Issuer to the Purchasers pursuant to the terms of this Agreement. For purposes of clarification, the Issuer hereby agrees to reimburse Schorr Parties, Passen Parties and SKH Investments LLC for all reasonable
fees, costs and expenses incurred in connection with the transactions contemplated hereby promptly upon receipt of a request for payment thereof accompanied by reasonable documentation of such expenses. 

Section 9.17 Specific Performance. Issuer recognizes that money damages may be inadequate to compensate the Holders for
a breach by the Issuer of its obligations hereunder, and the Issuer irrevocably agrees that the Holders shall be entitled to the remedy of specific performance or the granting of such other equitable remedies as may be awarded by a court of
competent jurisdiction in order to afford the Holders the benefits of this Agreement and that Issuer shall not object and hereby waive any right to object to such remedy or such granting of other equitable remedies on the grounds that money damages
will be sufficient to compensate the Holders. 
 Section 9.18 Termination of Prior Agreements. For the
avoidance of doubt, upon the effectiveness of this Agreement, the Original Note Purchase Agreement and the First Amended Purchase Agreement shall be deemed amended and restated and superseded in their entirety by this Agreement and neither the
Original Note Purchase Agreement or the First Amended Purchase Agreement shall have any further force or effect.

 SECTION 10 

GUARANTEE 

Section 10.1 The Guaranty. The Guarantor hereby guarantees as a primary obligor and not as a surety to each Purchaser
and each subsequent Holder the prompt payment in full when due (whether upon stated maturity, demand, by acceleration or otherwise) of the principal of and interest (including any interest, fees, costs or charges that would accrue but for the
provisions of the Bankruptcy Code after any bankruptcy or insolvency petition under the Bankruptcy Code) on the Notes held by the Holders thereof, and all other Note Obligations from time to time owing to the Holders by the Issuer, under this
Agreement and under the Notes and by the Issuer under any of the other Transaction Documents, and all Note Obligations of the Issuer to any Holder, in each case strictly in accordance with the terms thereof (such obligations being herein
collectively called the “Guaranteed Obligations”). The Guarantor hereby agrees that if the Issuer 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. 

Section 10.2 Obligations Unconditional. The obligations of the Guarantor under Section 10.1 are absolute,
irrevocable and unconditional, irrespective of the value, genuineness, validity, regularity, avoidance, subordination or enforceability of the obligations of the Issuer under this Agreement, the Notes 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: 

(a) 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; 
 (b) any of the acts
mentioned in any of the provisions of this Agreement or the Notes or any other agreement or instrument referred to herein or therein shall be done or omitted; 

(c) 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, the Notes or any other Transaction Document 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; 
  

 – 74 – 








 (d) any Lien or security interest granted to, or in favor of, any Holder 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 Collateral Documents; 

(e) the consent, forbearance or granting of any indulgence by, or on behalf of Holders with respect to any provision of any of the
Transaction Documents; 
 (f) the election of any remedy available under the Transaction Documents, or on behalf of, the
Holders with respect to all or any part of the Guaranteed Obligations; 
 (g) the absence of any attempt by, or on behalf
of, the Holders to collect, or to take any other action to enforce, all or any part of the Guaranteed Obligations whether from or against the Issuer or any other Person; 

(h) the election by, or on behalf of, the Holders, in any proceeding instituted under Chapter 11 of the Bankruptcy Code with respect
to the Issuer or the Guarantor, of the application of Section 1111(b)(2) of the Bankruptcy Code; 
 (i) any borrowing
or grant of a security interest by the Issuer, as debtor-in-possession, under Section 364 of the Bankruptcy Code; or 

(j) the disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of the claims against the Issuer held by
any of the Holders, for repayment of all or any part of the Guaranteed Obligations or any expenses. 
 The Guarantor hereby
expressly waive diligence, presentment, demand of payment, filing of claims with a court in the event of receivership or bankruptcy of the Issuer 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 the Holders or any Affiliates thereof exhaust any right, power or remedy or proceed against the Issuer under this Agreement or the Notes 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 Purchaser thereof or the Holders upon this Guaranty 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 Guaranty, and all dealings between the Issuer and the Holders 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 the Holders thereof, and the
obligations and liabilities of the Guarantor hereunder shall not be conditioned or contingent upon the pursuit by the Holders thereof or any other Person at any time of any right or remedy against the Issuer 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 
  

 – 75 – 








 
thereof, and shall inure to the benefit of the Holders, and their successors and assigns, notwithstanding that from time to time during the term of this Agreement there may be no Guaranteed
Obligations outstanding. 
 Section 10.3 Reinstatement. The obligations of the Guarantor under this
Section 10 shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of the Issuer 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 the Holders on demand for all reasonable costs and expenses (including reasonable fees of
counsel) incurred by the Holders 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. 

Section 10.4 Subrogation; Subordination. 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 Section 10.1, whether by subrogation or otherwise, against the Issuer 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 the Issuer now or hereafter owing to any Guarantor by reason of any payment by such Guarantor
under the Guaranty in this Section 10 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 the Issuer to such Guarantor until the Note 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 the Issuer is dissolved or if substantially all of the assets of the Issuer 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 the Holders and be paid over to Holders 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. 

Section 10.5 Remedies. The Guarantor agrees that, as between such Guarantor and the Holders, the obligations of the
Issuer under this Agreement and the Notes may be declared to be forthwith due and payable as provided in Section 8 (and shall be deemed to have become automatically due and payable in the circumstances provided in
Section 8.2) for purposes of Section 10.1, notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming automatically due and payable) as against the Issuer 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 the Issuer) shall forthwith become due and payable by the Guarantor for
purposes of Section 10.1. 
  

 – 76 – 








 Section 10.6 Instrument for the Payment of Money. The Guarantor hereby
acknowledges that the guarantee in this Section 10 constitutes an instrument for the payment of money, and consents and agrees that the Holders, at their sole option, in the event of a dispute by such Guarantor in the payment of any
moneys due hereunder, shall have the right to bring a motion-action under New York CPLR Section 3213. 

Section 10.7 Continuing Guaranty. The Guaranty in this Section 10 is a continuing guarantee, and shall
apply to all Guaranteed Obligations whenever arising. 
 Section 10.8 General Limitation on Guaranty
Obligations. 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 a Guarantor under
Section 10.1 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 Section 10.1, then,
notwithstanding any other provision to the contrary, the amount of such liability shall, without any further action by such Guarantor, the Holders 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. 

Section 10.9 Authorization to Amend. Holders are 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 the Transaction Documents in accordance and pursuant to the terms of the relevant Transaction 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 the Issuer, 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 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. 
 Section 10.10 Enforcement; Application of Payments. Upon the
occurrence and during the continuance of an Event of Default, the Tranche B Requisite Holders, and upon the occurrence and continuation of an Event of Default described in Section 8.1(a)(i) above, the Tranche A Requisite Holders, may
proceed directly and at once, 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 the Holders, without first proceeding against the Issuer
or any other Person, or against any security or collateral for the Guaranteed Obligations. Subject only to the terms and provisions of the Collateral Documents and this Agreement, the 

 

 – 77 – 








 
Tranche B Requisite Holders and, following the Maturity Date of the Notes, the Tranche A Requisite Holders shall have the exclusive right to determine the application of payments and credits, if
any, from the Guarantor, the Issuer or any other Person, on account of the Guaranteed Obligations or any other liability of the Guarantor to any of the Holders. For the avoidance of doubt, all such application of payments and credits shall all at
all times be applied pro rata among the outstanding Tranche A Notes and outstanding Tranche B Notes. 

Section 10.11 Financial Information. The Guarantor hereby assumes responsibility for keeping itself informed of the
financial condition of the Issuer 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 the Guarantor hereby agrees that the Holders shall have no duty to advise any Guarantor of information known to it regarding such condition or any such circumstances. In the event any of the Holders, in its sole discretion,
undertakes at any time or from time to time to provide any such information to any Guarantor, such Holder 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 Holder, 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. 
 Section 10.12 No Marshalling. The Guarantor consents and agrees that none of the Holders or any
Person acting for or on behalf of the Holders, 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. 

Section 10.13 Enforcement; Amendments; Waivers. No delay on the part of any of the Holders in the exercise of any right
or remedy arising under this Guaranty, the Collateral Documents, any of the other Transaction Documents 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 any of the Holders 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 any of the Holders or the Collateral Agent, except as expressly set forth in a writing duly signed and delivered by the Collateral Agent and the Requisite Tranche B Holders. Failure by any of the Holders at any
time or times hereafter to require strict performance by the Issuer, 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 the
Transaction Documents now or at any time or times hereafter executed by such Persons and delivered to any of the Holders shall not waive, affect or diminish any right of any of the Holders 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 any of the Holders (or their respective agents, officers or employees), unless such waiver is contained in an instrument in writing, directed and delivered to
the Issuer or the Guarantor, as applicable, specifying such waiver, and is signed by the Tranche B Requisite Holders. No waiver of any Event of Default by the Holders 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 any of the Holders permitted hereunder shall in any way affect or impair any Holder’s rights and remedies or the obligations of the Guarantor under this Guaranty. 

 

 – 78 – 








 
Any determination by a court of competent jurisdiction of the amount of any principal and/or interest owing by the Issuer to any Holder 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. 

Section 10.14 Release of Guarantor. Upon (i) any disposition by the Issuer of 100% of its equity interests in
Guarantor to any non-affiliated Person for fair value in all respects pursuant to Section 5.2(g) 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 Note Obligations then the Collateral Agent will immediately release its lien on the assets of Guarantor and the Guarantor’s obligations under this Section 10 shall terminate, and the Collateral Agent and the
Holders shall execute and deliver to Guarantor reasonable and customary documentation effecting the same, at Guarantor’s reasonable expense.
