co-agents from time to time party thereto, as amended, modified or supplemented
from time to time.

“Guaranteed Obligations” means, collectively:

(a)    all covenants, agreements, terms, conditions and indemnities to be
performed and observed by any Originator under and pursuant to the Sale
Agreement and each other document executed and delivered by any Originator
pursuant to the Sale Agreement, including, without limitation, the due and
punctual payment of all sums which are or may become due and owing by any

2

--------------------------------------------------------------------------------

performance of all Guaranteed Obligations of each Originator under the
Agreements and each other document executed and delivered by any Originator
pursuant to the Agreements and is in no way conditioned upon any requirement
that Recipient first attempt to collect any amounts owing by any Originator to
Recipient, the Agents or the Lenders from any other Person or resort to any
collateral security, any balance of any deposit account or credit on the books
of Recipient, the Agents or any Lender in favor of any Originator or any other
Person or other means of obtaining payment. Should any Originator default in the
payment or performance of any of its Guaranteed Obligations, Recipient (or its

the enforcement thereof, together with interest on amounts recoverable under
this Undertaking from the time when such amounts become due until payment, at a
rate of interest (computed for the actual number of days elapsed based on a 360
day year) equal to the Prime Rate plus 2% per annum, such rate of interest
changing when and as the Prime Rate changes.

Section 4.    Waivers by Performance Guarantors. Each Performance Guarantor
waives notice of acceptance of this Undertaking, notice of any action taken or
omitted by Recipient (or its assigns) in reliance on this Undertaking, and any
requirement that Recipient (or its assigns) be diligent or prompt in making
demands under this Undertaking, giving notice of any Termination Event,
Amortization Event, other default or omission by any Originator or asserting any
other rights of Recipient under this Undertaking. Each Performance Guarantor
warrants that it has adequate means to obtain from each Originator, on a
continuing basis, information concerning the financial condition of such
Originator, and that it is not relying on Recipient to provide such information,
now or in the future. Each Performance Guarantor also irrevocably waives all
defenses (i) that at any time may be available in respect of the Obligations by
virtue of any statute of limitations, valuation, stay, moratorium law or other
similar law now

3

--------------------------------------------------------------------------------

impairment of collateral. Recipient (and its assigns) shall be at liberty,
without giving notice to or obtaining the assent of either Performance Guarantor
and without relieving either Performance Guarantor of any liability under this
Undertaking, to deal with each Originator and with each other party who now is
or after the date hereof becomes liable in any manner for any of the Guaranteed
Obligations, in such manner as Recipient in its sole discretion deems fit, and
to this end each Performance Guarantor agrees that the validity and
enforceability of this Undertaking, including without limitation, the provisions
of Section 7 hereof, shall not be impaired or affected by any of the following:
(a) any extension, modification or renewal of, or indulgence with respect to, or
substitutions for, the Guaranteed Obligations or any part thereof or any
agreement relating thereto at any time; (b) any failure or omission to enforce
any right, power or remedy with respect to the Guaranteed Obligations or any
part thereof or any agreement relating thereto, or any collateral securing the
Guaranteed Obligations or any part thereof; (c) any waiver of any right, power
or remedy or of any Termination Event, Amortization Event, or default with
respect to the Guaranteed Obligations or any part thereof or any agreement
relating thereto; (d) any release, surrender, compromise, settlement, waiver,
subordination or modification, with or without consideration, of any other
obligation of any person or entity with respect to the Guaranteed Obligations or
any part thereof; (e) the enforceability or validity of the Guaranteed
Obligations or any part thereof or the genuineness, enforceability or validity
of any agreement relating thereto or with respect to the Guaranteed Obligations
or any part thereof; (f) the application of payments received from any source to
the payment of any payment Obligations of any Originator or any part thereof or
amounts which are not covered by this Undertaking even though Recipient (or its
assigns) might lawfully have elected to apply such payments to any part or all
of the payment Obligations of such Originator or to amounts which are not
covered by this Undertaking; (g) the existence of any claim, setoff or other
rights which either Performance Guarantor may have at any time against any
Originator in connection herewith or any unrelated transaction; (h) any
assignment or transfer of the Guaranteed Obligations or any part thereof; or (i)
any failure on the part of any Originator to perform or comply with any term of
the Agreements or any other document executed in connection therewith or
delivered thereunder, all whether or not either Performance Guarantor shall have
had notice or knowledge of any act or omission referred to in the foregoing
clauses (a) through (i) of this Section 4.

Section 5.    Unenforceability of Guaranteed Obligations Against Originators.
Notwithstanding (a) any change of ownership of any Originator or the insolvency,
bankruptcy or any other change in the legal status of any Originator; (b) the
change in or the imposition of any law, decree, regulation or other governmental
act which does or might impair, delay or in any way affect the validity,
enforceability or the payment when due of the Guaranteed Obligations; (c) the
failure of any Originator or either Performance Guarantor to maintain in full
force, validity or effect or to obtain or renew when required all governmental
and other approvals, licenses or consents required in connection with the
Guaranteed Obligations or this Undertaking, or to take any other action required
in connection with the performance of all obligations pursuant to the Guaranteed
Obligations or this Undertaking; or (d) if any of the moneys included

4

--------------------------------------------------------------------------------

in the Guaranteed Obligations have become irrecoverable from any Originator for
any other reason other than final payment in full of the payment Obligations in
accordance with their terms, this Undertaking shall nevertheless be binding on
each Performance Guarantor. This Undertaking shall be in addition to any other
guaranty or other security for the Guaranteed Obligations, and it shall not be
rendered unenforceable by the invalidity of any such other guaranty or security.
In the event that acceleration of the time for payment of any of the Guaranteed
Obligations is stayed upon the insolvency, bankruptcy or reorganization of any
Originator or for any other reason with respect to any Originator, all such
amounts then due and owing with respect to the Guaranteed Obligations under the
terms of the Agreements, or any other agreement evidencing, securing or
otherwise executed in connection with the Guaranteed Obligations, shall be
immediately due and payable by the Performance Guarantors.

Section 6.    Representations and Warranties. Each Performance Guarantor hereby
represents and warrants to Recipient that:

(a)    Existence and Standing. Each Performance Guarantor is a corporation duly
organized, validly existing and in good standing under the laws of its state of
incorporation. Each Performance Guarantor is duly qualified to do business and
is in good standing as a foreign corporation, and has and holds all corporate
power and all governmental licenses, authorizations, consents and approvals
required to carry on its business in each jurisdiction in which its business is
conducted except where the failure to so qualify or so hold would not reasonably
be expected to have a Material Adverse Effect.

(b)    Authorization, Execution and Delivery; Binding Effect. The execution and
delivery by each Performance Guarantor of this Undertaking, and the performance
of its obligations hereunder, are within its corporate powers and authority and
have been duly authorized by all necessary corporate action on its part. This
Undertaking has been duly executed and delivered by each Performance Guarantor.
This Undertaking constitutes the legal, valid and binding obligation of each
Performance Guarantor enforceable against each Performance Guarantor in
accordance with their respective terms, except as such enforcement may be
limited by applicable bankruptcy, insolvency, reorganization or other similar
laws relating to or limiting creditors’ rights generally and by general
principles of equity (regardless of whether enforcement is sought in a
proceeding in equity or at law).

(c)    No Conflict; Government Consent. The execution and delivery by each
Performance Guarantor of this Undertaking, and the performance of such
Performance Guarantor’s obligations hereunder do not contravene or violate (i)
its certificate or articles of incorporation or by-laws, (ii) any law, rule or
regulation applicable to it, (iii) any restrictions under any agreement,
contract or instrument to which it is a party or by which it or any of its
property is bound, or (iv) any order, writ, judgment, award, injunction or
decree binding on or affecting it or its property, and do not result in the
creation or imposition of any Adverse Claim on assets of Performance Guarantor
or its Subsidiaries (except as created hereunder) except, in

5

--------------------------------------------------------------------------------

any case, where such contravention or violation would not reasonably be expected
to have a Material Adverse Effect. With respect to the transactions contemplated
under this Undertaking and the Agreements, each Performance Guarantor and each
of its respective Subsidiaries is in compliance in all material respects with
all laws, rules and regulations promulgated by the U.S. Treasury Department
Office of Foreign Assets Control pursuant to the International Emergency
Economic Powers Act, 50 U.S.C. §§ 1701 et. seq., The Trading with the Enemy Act,
50 U.S.C. App. 1 et seq., and any Executive Order promulgated thereunder
(including, without limitation, having in full force and effect any required
licenses thereunder).

(d)    Financial Statements. The consolidated financial statements of each
Performance Guarantor and its consolidated Subsidiaries dated as of June 30,
2015 heretofore delivered to Recipient have been prepared in accordance with
generally accepted accounting principles consistently applied and fairly present
in all material respects the consolidated financial condition and results of
operations of Performance Guarantor and its consolidated Subsidiaries as of such
dates and for the periods ended on such dates. Since the later of (i) June 30,
2015 and (ii) the last time this representation was made or deemed made, no
event has occurred which would reasonably be expected to have a Material Adverse
Effect.

(e)    Taxes. Each Performance Guarantor has filed all United States federal tax
returns and all other tax returns which are required to be filed and have paid
all taxes due pursuant to said returns or pursuant to any assessment received by
such Performance Guarantor or any of its respective Subsidiaries, except such
taxes, if any, as are being contested in good faith and as to which adequate
reserves have been provided. No federal or state tax liens have been filed and
no claims are being asserted with respect to any such taxes. The charges,
accruals and reserves on the books of each Performance Guarantor in respect of
any taxes or other governmental charges are adequate.

(f)    Litigation and Contingent Obligations. Except as disclosed in the filings
made by each Performance Guarantor with the Securities and Exchange Commission,
there are no actions, suits or proceedings pending or, to the best of such
Performance Guarantor’s knowledge threatened against or affecting such
Performance Guarantor or any of its properties, in or before any court,
arbitrator or other body, that could reasonably be expected to have a material
adverse effect on (i) the business, properties, condition (financial or
otherwise) or results of operations of such Performance Guarantor and its
Subsidiaries taken as a whole, (ii) the ability of such Performance Guarantor to
perform its obligations under this Undertaking, or (iii) the validity or
enforceability of any of this Undertaking or the rights or remedies of Recipient
hereunder. Neither Performance Guarantor has any material Contingent Obligations
not provided for or disclosed in the financial statements referred to in Section
6(d).

(g)    ERISA. (i) Identification of Plans. Except as disclosed on Exhibit III-B
of the Credit and Security Agreement, as of the closing date or as of the last
date Exhibit III-B of the Credit and Security Agreement was updated to reflect
the establishment of a new Plan, neither of the

6

--------------------------------------------------------------------------------

Performance Guarantors, nor their respective Restricted Subsidiaries nor any of
their respective ERISA Affiliates maintains or contributes to, or has during the
past seven (7) years maintained or contributed to, any material Plan that is
subject to Title IV of ERISA.

(ii)    Compliance. Each Plan maintained by each Performance Guarantor, its
respective Restricted Subsidiaries and any of their respective ERISA Affiliates
has at all times been maintained, by its terms and in operation, in compliance
with all applicable laws, and the Performance Guarantor and its Restricted
Subsidiaries are subject to no tax or penalty with respect to any Plan of such
Person or any ERISA Affiliate thereof, including, without limitation, any tax or
penalty under Title I or Title IV of ERISA or under Chapter 43 of the Tax Code,
or any tax or penalty resulting from a loss of deduction under Sections 162,
404, or 419 of the Tax Code, where the failure to comply with such laws, and
such taxes and penalties, together with all other liabilities referred to in
this Section 6(g) (taken as a whole), would in the aggregate have a Material
Adverse Effect;

(iii)    Liabilities. Neither of the Performance Guarantors, nor their
respective Restricted Subsidiaries nor any of their respective ERISA Affiliates
is subject to any liabilities (including withdrawal liabilities) with respect to
any Plans of either Performance Guarantor, their respective Restricted
Subsidiaries or any of their respective ERISA Affiliates, including, without
limitation, any liabilities arising from Titles I or IV of ERISA, other than
obligations to fund benefits under an ongoing Plan and to pay current
contributions, expenses and premiums with respect to such Plans, where such
liabilities, together with all other liabilities referred to in this Section
6(g) (taken as a whole), would in the aggregate have a Material Adverse Effect.

(iv)    Funding. Each Performance Guarantor and its respective Restricted
Subsidiaries, with respect to any Plan which is subject to Title IV of ERISA,
each of their respective ERISA Affiliates, have made full and timely payment of
all amounts (A) required to be contributed under the terms of each Plan and
applicable law, and (B) required to be paid as expenses (including PBGC or other
premiums) of each Plan, where the failure to pay such amounts (when taken as a
whole, including any penalties attributable to such amounts) would have a
Material Adverse Effect. Neither Performance Guarantor, nor their Restricted
Subsidiaries nor any of their respective ERISA Affiliates is subject to any
liabilities with respect to post-retirement medical benefits in any amounts
which, together with all other liabilities referred to in this Section 6(g)
(taken as a whole), would have a Material Adverse Effect if such amounts were
then due and payable.

(v)    ERISA Event. No ERISA Event has occurred or is reasonably expected to
occur, except for such ERISA Event that individually or in the aggregate would
not have a Material Adverse Effect.

Section 7.    Subrogation; Subordination. Notwithstanding anything to the
contrary contained herein, until the Guaranteed Obligations are paid in full
each Performance Guarantor: (a) will not enforce or otherwise exercise any right
of subrogation to any of the rights

7

--------------------------------------------------------------------------------

of Recipient, the Agents or any Lender against any Originator, (b) hereby waives
all rights of subrogation (whether contractual, under Section 509 of the United
States Bankruptcy Code, at law or in equity or otherwise) to the claims of
Recipient, the Agents and the Lenders against any Originator and all
contractual, statutory or legal or equitable rights of contribution,
reimbursement, indemnification and similar rights and “claims” (as that term is
defined in the United States Bankruptcy Code) which such Performance Guarantor
might now have or hereafter acquire against any Originator that arise from the
existence or performance of such Performance Guarantor’s obligations hereunder,
(c) will not claim any setoff, recoupment or counterclaim against any Originator
in respect of any liability of such Performance Guarantor to such Originator and
(d) waives any benefit of and any right to participate in any collateral
security which may be held by Recipient, the Agents or the Lenders. The payment
of any amounts due with respect to any indebtedness of any Originator now or
hereafter owed to either Performance Guarantor is hereby subordinated to the
prior payment in full of all of the Guaranteed Obligations. Each Performance
Guarantor agrees that, after the occurrence of any default in the payment or
performance of any of the Guaranteed Obligations, such Performance Guarantor
will not demand, sue for or otherwise attempt to collect any such indebtedness
of any Originator to such Performance Guarantor until all of the Guaranteed
Obligations shall have been paid and performed in full. If, notwithstanding the
foregoing sentence, either Performance Guarantor shall collect, enforce or
receive any amounts in respect of such indebtedness while any Obligations are
still unperformed or outstanding, such amounts shall be collected, enforced and
received by such Performance Guarantor as trustee for Recipient (and its
assigns) and be paid over to Recipient (or its assigns) on account of the
Guaranteed Obligations without affecting in any manner the liability of such
Performance Guarantor under the other provisions of this Undertaking. The
provisions of this Section 7 shall be supplemental to and not in derogation of
any rights and remedies of Recipient under any separate subordination agreement
which Recipient may at any time and from time to time enter into with each
Performance Guarantor.

Section 8.    Termination of Performance Undertaking. Each Performance
Guarantor’s obligations hereunder shall continue in full force and effect until
all Obligations are finally paid and satisfied in full and the Credit and
Security Agreement is terminated, provided that this Undertaking shall continue
to be effective or shall be reinstated, as the case may be, if at any time
payment or other satisfaction of any of the Guaranteed Obligations is rescinded
or must otherwise be restored or returned upon the bankruptcy, insolvency, or
reorganization of any Originator or otherwise, as though such payment had not
been made or other satisfaction occurred, whether or not Recipient (or its
assigns) is in possession of this Undertaking. No invalidity, irregularity or
unenforceability by reason of the Bankruptcy Code or any insolvency or other
similar law, or any law or order of any government or agency thereof purporting
to reduce, amend or otherwise affect the Guaranteed Obligations shall impair,
affect, be a defense to or claim against the obligations of either Performance
Guarantor under this Undertaking.

Section 9.    Effect of Bankruptcy. This Performance Undertaking shall survive
the insolvency of any Originator and the commencement of any case or proceeding
by or against

8

--------------------------------------------------------------------------------

any Originator under the Bankruptcy Code or other federal, state or other
applicable bankruptcy, insolvency or reorganization statutes. No automatic stay
under the Bankruptcy Code with respect to any Originator or other federal, state
or other applicable bankruptcy, insolvency or reorganization statutes to which
any Originator is subject shall postpone the obligations of either Performance
Guarantor under this Undertaking.

Section 10.    Setoff. Regardless of the other means of obtaining payment of any
of the Guaranteed Obligations, Recipient (and its assigns) is hereby authorized
at any time and from time to time, without notice to either Performance
Guarantor (any such notice being expressly waived by Performance Guarantor) and
to the fullest extent permitted by law, to set off and apply any deposits and
other sums against the obligations of Performance Guarantor under this
Undertaking, whether or not Recipient (or any such assign) shall have made any
demand under this Undertaking and although such Obligations may be contingent or
unmatured.

Section 11.    Taxes. All payments to be made by either Performance Guarantor
hereunder shall be made free and clear of any deduction or withholding. If
either Performance Guarantor is required by law to make any deduction or
withholding on account of tax or otherwise from any such payment, the sum due
from it in respect of such payment shall be increased to the extent necessary to
ensure that, after the making of such deduction or withholding, Recipient
receive a net sum equal to the sum which they would have received had no
deduction or withholding been made.

Section 12.    Further Assurances. Each Performance Guarantor agrees that it
will from time to time, at the request of Recipient (or its assigns), provide
information relating to the business and affairs of such Performance Guarantor
as Recipient may reasonably request. Each Performance Guarantor also agrees to
do all such things and execute all such documents as Recipient (or its assigns)
may reasonably consider necessary or desirable to give full effect to this
Undertaking and to perfect and preserve the rights and powers of Recipient
hereunder.

Section 13.    Successors and Assigns. This Performance Undertaking shall be
binding upon each Performance Guarantor, its successors and permitted assigns,
and shall inure to the benefit of and be enforceable by Recipient and its
successors and assigns. Neither Performance Guarantor may assign or transfer any
of its obligations hereunder without the prior written consent of each of
Recipient and each Agent. Without limiting the generality of the foregoing
sentence, Recipient may assign or otherwise transfer the Agreements, any other
documents executed in connection therewith or delivered thereunder or any other
agreement or note held by them evidencing, securing or otherwise executed in
connection with the Guaranteed Obligations, or sell participations in any
interest therein, to any other entity or other person, and such other entity or
other person shall thereupon become vested, to the extent set forth in the
agreement evidencing such assignment, transfer or participation, with all the
rights in respect thereof granted to the Recipient herein.

9

--------------------------------------------------------------------------------

Section 14.    Amendments and Waivers. No amendment or waiver of any provision
of this Undertaking nor consent to any departure by either Performance Guarantor
therefrom shall be effective unless the same shall be in writing and signed by
Recipient, the Agents and each Performance Guarantor. No failure on the part of
Recipient to exercise, and no delay in exercising, any right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
right hereunder preclude any other or further exercise thereof or the exercise
of any other right.

Section 15.    Notices. All notices and other communications provided for
hereunder shall be made in writing and shall be addressed as follows: if to the
Performance Guarantor, at the addresses set forth beneath its respective
signature hereto, and if to Recipient, at the addresses set forth beneath its
signature hereto, or at such other addresses as each of the Performance
Guarantors or any Recipient may designate in writing to the others. Each such
notice or other communication shall be effective (1) if given by telecopy, upon
the receipt thereof, (2) if given by mail, three (3) Business Days after the
time such communication is deposited in the mail with first class postage
prepaid or (3) if given by any other means, when received at the address
specified in this Section 15.

Section 16.    GOVERNING LAW. THIS UNDERTAKING SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK
(INCLUDING FOR SUCH PURPOSE SECTIONS 5-1401 AND 5-1402 OF THE GENERAL
OBLIGATIONS LAW OF THE STATE OF NEW YORK).

Section 17.    CONSENT TO JURISDICTION. EACH PARTY TO THIS UNDERTAKING HEREBY
IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES
FEDERAL OR NEW YORK STATE COURT SITTING IN NEW YORK, NEW YORK, IN ANY ACTION OR
PROCEEDING ARISING OUT OF OR RELATING TO THIS UNDERTAKING OR ANY DOCUMENT
EXECUTED BY SUCH PERSON PURSUANT TO THIS UNDERTAKING, AND EACH SUCH PARTY HEREBY
IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY
BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION
IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM.
NOTHING HEREIN SHALL LIMIT THE RIGHT OF ANY AGENT OR ANY LENDER TO BRING
PROCEEDINGS AGAINST ANY LOAN PARTY IN THE COURTS OF ANY OTHER JURISDICTION. ANY
JUDICIAL PROCEEDING BY ANY LOAN PARTY AGAINST ANY AGENT OR ANY LENDER OR ANY
AFFILIATE OF ANY AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY
MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH THIS UNDERTAKING
OR ANY DOCUMENT EXECUTED BY SUCH LOAN PARTY PURSUANT TO THIS UNDERTAKING SHALL
BE BROUGHT ONLY IN A COURT IN NEW YORK, NEW YORK.

--------------------------------------------------------------------------------

Section 18.    Bankruptcy Petition. Each Performance Guarantor hereby covenants
and agrees that, prior to the date that is one year and one day after the
payment in full of all outstanding senior Debt of Recipient, it will not
institute against, or join any other Person in instituting against, Recipient
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings or other similar proceeding under the laws of the United States or
any state of the United States.

Section 19.    Miscellaneous. This Undertaking constitutes the entire agreement
of each Performance Guarantor with respect to the matters set forth herein. The
rights and remedies herein provided are cumulative and not exclusive of any
remedies provided by law or any other agreement, and this Undertaking shall be
in addition to any other guaranty of or collateral security for any of the
Guaranteed Obligations. The provisions of this Undertaking are severable, and in
any action or proceeding involving any state corporate law, or any state or
federal bankruptcy, insolvency, reorganization or other law affecting the rights
of creditors generally, if the obligations of either Performance Guarantor
hereunder would otherwise be held or determined to be avoidable, invalid or
unenforceable on account of the amount of such Performance Guarantor’s liability
under this Undertaking, then, notwithstanding any other provision of this
Undertaking to the contrary, the amount of such liability shall, without any
further action by either Performance Guarantor or Recipient, be automatically
limited and reduced to the highest amount that is valid and enforceable as
determined in such action or proceeding. Any provisions of this Undertaking
which are prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. Unless otherwise
specified, references herein to “Section” shall mean a reference to sections of
this Undertaking.
