satisfaction or payment in full of the Guarantied Obligations shall
mean the payment in full in cash (or cash collateralization in

at such time, are allowed by the applicable Bank Product Provider
to remain outstanding and are not required to be repaid or cash

Agreement or any Other Agreement and the full and final termination
of any commitment to extend any financial accommodations under the
Account Purchase Agreement and any Other Agreement. Any reference
herein to any Person shall be construed to include such
Person’s successors and assigns. Any requirement of a writing
contained herein shall be satisfied by the transmission of a Record

Guaranty.

 

2. Guarantied
Obligations. Guarantor hereby irrevocably and
unconditionally guaranties to WFB, for the benefit of itself and
the Bank Product Providers, as and for its own debt, until the
final and indefeasible payment in full thereof, in cash, has been
made, (a) the due and punctual payment of the Guarantied
Obligations, when and as the same shall become due and payable,
whether at maturity, pursuant to a mandatory prepayment
requirement, by acceleration, or otherwise; it being the intent of
Guarantor that the guaranty set forth herein shall be a guaranty of
payment and not a guaranty of collection; and (b) the punctual
and faithful performance, keeping, observance, and fulfillment by
Client of all of the agreements, conditions, covenants, and
obligations of Client contained in the Account Purchase Agreement
and in each of the Other Agreements.

 

3. Continuing
Guaranty. This Guaranty includes Guarantied Obligations
arising under successive transactions continuing, compromising,
extending, increasing, modifying, releasing, or renewing the
Guarantied Obligations, changing the interest rate, discount rate,
any charge or fee, payment terms, or other terms and conditions
thereof, or creating new or additional Guarantied Obligations after
prior Guarantied Obligations have been satisfied in whole or in
part. To the maximum extent permitted by law, Guarantor hereby
waives any right to revoke this Guaranty as to future Guarantied
Obligations. If such a revocation is effective notwithstanding the
foregoing waiver, Guarantor acknowledges and agrees that
(a) no such revocation shall be effective until written notice
thereof has been received by WFB, (b) no such revocation shall
apply to any Guarantied Obligations in existence on the date of
receipt by WFB of such written notice (including any subsequent
continuation, extension, or renewal thereof, or change in the
interest rate, payment terms, or other terms and conditions
thereof), (c) no such revocation shall apply to any Guarantied
Obligations made or created after such date to the extent made or
created pursuant to a legally binding commitment of WFB in
existence on the date of such revocation, (d) no payment by
Guarantor, Client, or from any other source, prior to the date of
WFB’s receipt of written notice of such revocation shall
reduce the maximum obligation of Guarantor hereunder, and
(e) any payment by Client or from any source other than
Guarantor subsequent to the date of such revocation shall first be
applied to that portion of the Guarantied Obligations as to which
the revocation is effective and which are not, therefore,
guarantied hereunder, and to the extent so applied shall not reduce
the maximum obligation of Guarantor hereunder.

 

4. Performance Under
this Guaranty. In the event that Client fails to make any
payment of any Guarantied Obligations, on or prior to the due date
thereof, or if Client shall fail to perform, keep, observe, or
fulfill any other obligation referred to in clause (b) of Section 2 of this Guaranty in
the manner provided in the Account Purchase Agreement or any of the
Other Agreements, Guarantor immediately shall cause, as applicable,
such payment in respect of the Guarantied Obligations to be made or
such obligation to be performed, kept, observed, or
fulfilled.

 

5. Primary
Obligations. This Guaranty is a primary and original
obligation of Guarantor, is not merely the creation of a surety
relationship, and is an absolute, unconditional, and continuing
guaranty of payment and performance which shall remain in full
force and effect without respect to future changes in conditions.
Guarantor hereby agrees that it is directly, jointly and severally
with any other guarantor of the Guarantied Obligations, liable to
WFB, for the benefit of itself and the Bank Product Providers, that
the obligations of Guarantor hereunder are independent of the
obligations of Client or any other guarantor, and that a separate
action may be brought against Guarantor, whether such action is
brought against Client or any other guarantor or whether Client or
any other guarantor is joined in such action. Guarantor hereby
agrees that its liability hereunder shall be immediate and shall
not be contingent upon the exercise or enforcement WFB or any Bank
Product Provider of whatever remedies they may have against Client
or any other guarantor, or the enforcement of any lien or
realization upon any security by WFB or any Bank Product Provider.
Guarantor hereby agrees that any release which may be given by WFB
to Client or any other guarantor, or with respect to any property
or asset subject to a Lien, shall not release Guarantor. Guarantor
consents and agrees that neither WFB nor any Bank Product Provider
shall be under any obligation to marshal any property or assets of
Client or any other guarantor in favor of Guarantor, or against or
in payment of any or all of the Guarantied
Obligations.

 

6. Waivers.

 

(a) To the fullest
extent permitted by applicable law, Guarantor hereby waives:
(i) notice of acceptance hereof; (ii) notice of the
purchase of any Acceptable Accounts or other financial
accommodations made or extended under the Account Purchase
Agreement, or the creation or existence of any Guarantied
Obligations; (iii) notice of the amount of the Guarantied
Obligations, subject, however, to Guarantor’s right to make
inquiry of WFB to ascertain the amount of the Guarantied
Obligations at any reasonable time; (iv) notice of any adverse
change in the financial condition of Client or of any other fact
that might increase Guarantor’s risk hereunder;
(v) notice of presentment for payment, demand, protest, and
notice thereof as to any instrument among the Account Purchase
Agreement and any of the Other Agreements; (vi) notice of any
default or Event of Default under the Account Purchase Agreement
and any of the Other Agreements; (vii) notice of intent to
accelerate and notice of acceleration; (viii) notice of any of the
events or circumstances enumerated in Section7; and (ix) all
other notices (except if such notice is specifically required to be
given to Guarantor under this Guaranty or any of the Other
Agreements to which Guarantor is a party) and demands to which
Guarantor might otherwise be entitled.

 

(b) To the fullest
extent permitted by applicable law, Guarantor hereby waives the
right by statute or otherwise to require WFB or any Bank Product
Provider to institute suit against Client or any other guarantor or
to exhaust any rights and remedies which WFB or any Bank Product
Provider has or may have against Client or any other guarantor. In
this regard, Guarantor agrees that it is bound to the payment of
each and all Guarantied Obligations, whether now existing or
hereafter arising, as fully as if the Guarantied Obligations were
directly owing to WFB or the Bank Product Providers, as applicable,
by Guarantor. Guarantor further waives any defense arising by
reason of any disability or other defense (other than the defense
that the Guarantied Obligations shall have been fully and finally
performed and indefeasibly paid in full in cash, to the extent of
any such payment) of Client or by reason of the cessation from any
cause whatsoever of the liability of Client in respect
thereof.

 

(c) To the fullest
extent permitted by applicable law, Guarantor hereby waives:
(i) any right to assert against WFB or any Bank Product
Provider, any defense (legal or equitable), set-off, counterclaim,
or claim which Guarantor may now or at any time hereafter have
against Client or any other party liable to WFB or any Bank Product
Provider; (ii) any defense, set-off, counterclaim, or claim,
of any kind or nature, arising directly or indirectly from the
present or future lack of perfection, sufficiency, validity, or
enforceability of the Guarantied Obligations or any security
therefor; (iii) any right or defense arising by reason of any
claim or defense based upon an election of remedies by WFB or any
Bank Product Provider including any defense based upon an
impairment or elimination of Guarantor’s rights of
subrogation, reimbursement, contribution, or indemnity of Guarantor
against Client or other guarantors or sureties; (iv) the
benefit of any statute of limitations affecting Guarantor’s
liability hereunder or the enforcement thereof, and any act which
shall defer or delay the operation of any statute of limitations
applicable to the Guarantied Obligations shall similarly operate to
defer or delay the operation of such statute of limitations
applicable to Guarantor’s liability hereunder.

 

(d) Until the
Guarantied Obligations have been paid in full in cash,
(i) Guarantor hereby postpones and agrees not to exercise any
right of subrogation Guarantor has or may have as against Client
with respect to the Guarantied Obligations; (ii) Guarantor
hereby postpones and agrees not to exercise any right to proceed
against Client or any other Person now or hereafter liable on
account of the Obligations for contribution, indemnity,
reimbursement, or any other similar rights (irrespective of whether
direct or indirect, liquidated or contingent); and
(iii) Guarantor hereby postpones and agrees not to exercise
any right it may have to proceed or to seek recourse against or
with respect to any property or asset of Client or any other Person
now or hereafter liable on account of the Obligations.
Notwithstanding anything to the contrary contained in this
Guaranty, Guarantor shall not exercise any rights of subrogation,
contribution, indemnity, reimbursement or other similar rights
against, and shall not proceed or seek recourse against or with
respect to any property or asset of, Client or any other guarantor
(including after payment in full of the Guarantied Obligations) if
all or any portion of the Obligations have been satisfied in
connection with an exercise of remedies in respect of the capital
stock of Client or such other guarantor whether pursuant to the
Account Purchase Agreement or otherwise.

 

(e) WITHOUT LIMITING
THE GENERALITY OF ANY OTHER WAIVER OR OTHER PROVISION SET FORTH IN
THIS GUARANTY, GUARANTOR WAIVES ALL RIGHTS AND DEFENSES ARISING OUT
OF AN ELECTION OF REMEDIES BY WFB OR ANY BANK PRODUCT PROVIDER,
EVEN THOUGH SUCH ELECTION OF REMEDIES, SUCH AS A NONJUDICIAL
FORECLOSURE WITH RESPECT TO SECURITY FOR THE GUARANTIED
OBLIGATIONS, HAS DESTROYED GUARANTOR’S RIGHTS OF SUBROGATION
AND REIMBURSEMENT AGAINST CLIENT BY THE OPERATION OF APPLICABLE
LAW.

 

(f) Without limiting
the generality of any other waiver or other provision set forth in
this Guaranty, Guarantor hereby also agrees to the following
waivers:

 

(i) WFB’s right
to enforce this Guaranty is absolute and is not contingent upon the
genuineness, validity or enforceability of the Guarantied
Obligations, the Account Purchase Agreement or any of the Other
Agreements. Guarantor agrees that WFB’s rights under this
Guaranty shall be enforceable even if Client had no liability at
the time of execution of the Other Agreements or the Guarantied
Obligations are unenforceable in whole or in part, or Client ceases
to be liable with respect to all or any portion of the Guarantied
Obligations.

 

(ii) Guarantor
agrees that WFB’s rights under the Account Purchase Agreement
and the Other Agreements will remain enforceable even if the amount
guaranteed hereunder is larger in amount and more burdensome than
that for which Client is responsible. The enforceability of this
Guaranty against Guarantor shall continue until all sums due under
the Account Purchase Agreement and the Other Agreements have been
paid in full and shall not be limited or affected in any way by any
impairment or any diminution or loss of value of any security or
collateral for Client’s obligations under the Account
Purchase Agreement or the Other Agreements, from whatever cause,
the failure of any security interest in any such security or
collateral or any disability or other defense of Client, any other
guarantor of Client’s obligations under any of the Other
Agreements, any pledgor of collateral for any Person’s
obligations to WFB or any other Person in connection with the
Account Purchase Agreement or the Other Agreements.

 

(iii) Guarantor
waives the right to require WFB to (A) proceed against Client,
any guarantor of Client’s obligations under the Account
Purchase Agreement or any of the Other Agreements, any other
pledgor of collateral for any Person’s obligations to WFB or
any other Person in connection with the Guarantied Obligations,
(B) proceed against or exhaust any other security or
collateral WFB may hold, or (C) pursue any other right or
remedy for Guarantor’s benefit, and agrees that WFB may
exercise its right under this Guaranty without taking any action
against Client, any other guarantor of Client’s obligations
under the Account Purchase Agreement or the Other Agreements, any
pledgor of collateral for any Person’s obligations to WFB or
any other Person in connection with the Guarantied Obligations, and
without proceeding against or exhausting any security or collateral
WFB holds.

 

(iv) Guarantor
waives, and agrees that its liability hereunder shall not be
affected by, any neglect, delay, omission, failure, or refusal of
WFB to (A) exercise or properly or diligently exercise any
right or remedy with respect to any or all of the Guarantied
Obligations or the collection thereof or any security interests or
liens or other security for or guaranty of the Guarantied
Obligations, or any portion thereof, (B) take or prosecute, or
properly or diligently take or prosecute, any action for the
collection of any or all of the Guarantied Obligations against
Client, Guarantor or any other Person in respect of any or all of
the Guarantied Obligations, (C) foreclose or prosecute, or
properly or diligently foreclose or prosecute, any action in
connection with any agreement, document or instrument or
arrangement evidencing, securing, or otherwise affecting all or any
part of the Guarantied Obligations, or (D) mitigate damages or
take any other action to reduce, collect, or enforce the Guarantied
Obligations.

 

7. Releases.
Guarantor consents and agrees that, without notice to or by
Guarantor and without affecting or impairing the obligations of
Guarantor hereunder, WFB or any Bank Product Provider may, by
action or inaction, compromise or settle, shorten or extend any
period of duration or the time for the payment of the Obligations,
or discharge the performance of the Obligations, or may refuse to
enforce the Obligations, or otherwise elect not to enforce the
Obligations, or may, by action or inaction, release all or any one
or more parties to, any one or more of the terms and provisions of
the Account Purchase Agreement or any of the Other Agreements or
may grant other indulgences to Client or any other guarantor in
respect thereof, or may amend or modify in any manner and at any
time (or from time to time) any one or more of the Obligations, the
Account Purchase Agreement or any of the Other Agreements
(including any increase or decrease in the principal amount of any
Obligations or the interest, fees or other amounts that may accrue
from time to time in respect thereof), or may, by action or
inaction, release or substitute the Client or any guarantor, if
any, of the Guarantied Obligations, or may enforce, exchange,
release, or waive, by action or inaction, any security for the
Guarantied Obligations or any other guaranty of the Guarantied
Obligations, or any portion thereof. Guarantor agrees that its
obligations under this Guaranty shall not be released, diminished,
impaired, reduced, or affected by the occurrence of any one or more
of the following events: (a) lack of organizational authority
of Client; (b) any receivership, insolvency, bankruptcy, or
other proceedings affecting Client or its property;
(c) partial or total release or discharge of Client or any
other Person from the performance of any obligation contained in
any instrument or agreement evidencing, governing, or securing all
or any part of the Guarantied Obligations, whether occurring
pursuant to any applicable law or otherwise; (d) any change in
the time, manner, or place of payment of, or in any other term of,
or any increase or decrease in the amount of, all the Guarantied
Obligations, or any portion thereof, or any other amendment or
waiver of any term of, or any consent to departure from any
requirement of, the Account Purchase Agreement or any of the Other
Agreements; (e) the taking or accepting of any collateral
security for all or any part of the Guarantied Obligations, this
Guaranty, or any other guaranty; (f) the taking or accepting
of any other guaranty for all or any part of the Guarantied
Obligations; (g) any failure to
acquire, perfect, or continue any security interest or lien on
Collateral securing all or any part of the Guarantied Obligations
or on any property securing this Guaranty; (h) any
exchange, release, or subordination of any security interest or
lien on any Collateral, or any release, amendment, waiver, or
subordination of any term of any guaranty of the Guarantied
Obligations or any other impairment of any collateral security or
guaranty now or hereafter securing all or any part of the
Guarantied Obligations; (i) any failure to dispose of any
collateral security at any time securing all or any part of the
Guarantied Obligations or this Guaranty in a commercially
reasonable manner or as otherwise may be required by any applicable
law; (j) any merger, reorganization, consolidation, or
dissolution of Client or any other Person at any time liable for
any of the Obligations, any sale, lease, or transfer of any or all
of the assets of Client or any other Person at any time liable for
any of the Obligations, or any change in name, business,
organization, location, composition, structure, or organization of
Client or any other Person at any time liable for any of the
Obligations; (k) any change of control or any other change in
the capitalization or equity interest ownership of Client or any
other Person at any time liable for any of the Obligations;
(l) any invalidity or unenforceability of or defect or
deficiency in the Account Purchase Agreement or any of the Other
Agreements; (m) avoidance or subordination of the Guarantied
Obligations, or any portion thereof, (n) the unenforceability of
all or any part of the Guarantied Obligations against Client
because any interest contracted for, charged, or received in
respect of the Guarantied Obligations exceeds the amount permitted
by any applicable law; (o) any waiver, consent, extension,
forbearance, or granting of any indulgence by WFB with respect to
the Guarantied Obligations or any provision of the Account Purchase
Agreement or any of the Other Agreements; (p) any delay in or
lack of enforcement of any remedies under the Account Purchase
Agreement or any of the Other Agreements);
(q) the act of creating all or any part of the Guarantied
Obligations is ultra vires, or the officers or other
representatives creating all or any part of the Guarantied
Obligations acted in excess of their authority; (r) any
election of remedies by WFB; (s) the Account Purchase
Agreement or any of the Other Agreements were forged; (t) the
election by WFB in any proceeding under the Bankruptcy Code of the
application of Section 1111(b)(2) thereof; (u) any borrowing
or grant of a security interest by Client as debtor-in-possession,
under Section 364 of the Bankruptcy Code; (v) any use by Client
(whether with the consent of WFB or otherwise) of cash collateral
during the pendency of any bankruptcy proceeding; (w) the
making of post-petition loans or any other provision for the
extension of post-petition credit to Client as debtor-in-possession
in any bankruptcy proceedings; (x) the disallowance in bankruptcy
of all or any portion of the claims of WFB for payment of any of
the Guarantied Obligations; or (y) any other circumstance
which might otherwise constitute a legal or equitable discharge or
defense available to Client or Guarantor (other than that the
Guarantied Obligations shall have been indefeasibly paid and
performed in full).

 

8. No Election.
WFB and the Bank Product Providers shall have the right to seek
recourse against Guarantor to the fullest extent provided for
herein and no election by WFB or any Bank Product Provider to
proceed in one form of action or proceeding, or against any party,
or on any obligation, shall constitute a waiver of WFB’s or
any Bank Product Provider’s right to proceed in any other
form of action or proceeding or against other parties unless WFB,
on behalf of itself or the Bank Product Providers, has expressly
waived such right in writing. Specifically, but without limiting
the generality of the foregoing, no action or proceeding by WFB or
the Bank Product Providers under any document or instrument
evidencing the Guarantied Obligations shall serve to diminish the
liability of Guarantor under this Guaranty except to the extent
that WFB and the Bank Product Providers finally and unconditionally
shall have realized indefeasible payment in full of the Guarantied
Obligations by such action or proceeding.

 

9. Revival and
Reinstatement. If the incurrence or payment of the
Guarantied Obligations or the obligations of Guarantor under this
Guaranty by Guarantor or the transfer by Guarantor to WFB of any
property of Guarantor should for any reason subsequently be
declared to be void or voidable under any state or federal law
relating to creditors’ rights, including provisions of the
Bankruptcy Code relating to fraudulent conveyances, preferences, or
other voidable or recoverable payments of money or transfers of
property (collectively, a “Voidable Transfer”), and if WFB is
required to repay or restore, in whole or in part, any such
Voidable Transfer, or elects to do so upon the reasonable advice of
its counsel, then, as to any such Voidable Transfer, or the amount
thereof that WFB is required or elects to repay or restore, and as
to all reasonable costs, expenses, and attorneys’ fees of WFB
related thereto, the liability of Guarantor automatically shall be
revived, reinstated, and restored and shall exist as though such
Voidable Transfer had never been made.

 

10. Financial Condition
of Client. Guarantor represents and warrants to WFB and the
Bank Product Providers that Guarantor is currently informed of the
financial condition of Client and of all other circumstances which
a diligent inquiry would reveal and which bear upon the risk of
nonpayment of the Guarantied Obligations. Guarantor further
represents and warrants to WFB and the Bank Product Providers that
Guarantor has read and understands the terms and conditions of the
Account Purchase Agreement and each of the Other Agreements.
Guarantor hereby covenants that it will continue to keep itself
informed of Client’s financial condition, the financial
condition of other guarantors, if any, and of all other
circumstances which bear upon the risk of nonpayment or
nonperformance of the Guarantied Obligations.

 

11. Payments;
Application. All payments to be made hereunder by Guarantor
shall be made in U.S. Dollars, in immediately available funds, and
without deduction (whether for taxes or otherwise) or offset and
shall be applied to the Guarantied Obligations in accordance with
the terms of the Account Purchase Agreement.

 

12. Attorneys Fees and
Costs. Guarantor agrees to pay, on demand, all
attorneys’ fees and all other costs and expenses which may be
incurred by WFB in connection with the enforcement of this Guaranty
or in any way arising out of, or consequential to, the protection,
assertion, or enforcement of the Guarantied Obligations (or any
security therefor), irrespective of whether suit is
brought.

 

13. Notices. All
notices and other communications hereunder to WFB shall be in
writing and shall be mailed, sent, or delivered in accordance with
provisions of the Account Purchase Agreement applicable to notices
and other communications thereunder. All notices and other
communications hereunder to Guarantor shall be in writing and shall
be mailed, sent, or delivered in care of Client in accordance with
the provisions of the Account Purchase Agreement applicable to
notices and other communications thereunder.

 

14. Cumulative
Rights. The rights, powers and remedies provided in this
Guaranty and in the Account Purchase Agreement and the Other
Agreements are cumulative, may be exercised concurrently, or
separately, may be exercised from time to time and in such order as
WFB shall determine, subject to the provisions of this Guaranty,
and are in addition to, and not exclusive of, the rights, powers,
and remedies provided by existing or future applicable laws.
WFB’s failure or delay to exercise or enforce, in whole or in
part, any right, power or remedy under this Guaranty, the Account
Purchase Agreement or any Other Agreement, shall not constitute a
waiver thereof, nor preclude any other or further exercise
thereof.

 

15. Severability of
Provisions. In the event any provision of this Guaranty (or
any part of any provision) is held by a court of competent
jurisdiction to be invalid, illegal or unenforceable in any
respect, such invalidity, illegality or unenforceability shall not
affect any other provision (or remaining part of the affected
provision) of this Guaranty, but this Guaranty shall be construed
as if such invalid, illegal or unenforceable provision (or part
thereof) had not been contained in this Guaranty, but only to the
extent it is invalid, illegal or unenforceable.

 

16. Entire Agreement;
Amendments. This Guaranty is intended by WFB and Guarantor
to be a complete, exclusive and final expression of the agreements
contained herein. Neither WFB nor Guarantor shall hereafter have
any rights under any prior agreements pertaining to the matters
addressed by this Guaranty but shall look solely to this Guaranty
for definition and determination of all of their respective rights,
liabilities and responsibilities under this Guaranty. Except as
otherwise provided herein, this Guaranty may not be supplemented,
changed, waived, discharged, terminated, modified or amended,
except by written instrument executed by the parties. THIS GUARANTY
AND THE OTHER AGREEMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE
PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.
THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

 

17. Successors and
Assigns. This Guaranty binds and is for the benefit of the
heirs, executors, administrators, successors and assigns of the
parties hereto, except that Guarantor shall not have the right to
assign its rights hereunder or any interest herein without
WFB’s prior written consent.

 

18. No Third Party
Beneficiary. This Guaranty is solely for the benefit of each
of WFB, each Bank Product Provider, and each of their successors
and assigns and may not be relied on by any other
Person.

 

19. Governing
Law. This Guaranty
shall be governed by, and construed and interpreted in accordance
with, the law of the State of Texas (the “Applicable State”),
without giving effect to the principles of conflicts of
laws.

 

20. ARBITRATION.

 

(a) ARBITRATION. THE PARTIES HERETO
AGREE, UPON DEMAND BY ANY PARTY, WHETHER MADE BEFORE THE
INSTITUTION OF A JUDICIAL PROCEEDING OR NOT MORE THAN 60 DAYS AFTER
SERVICE OF A COMPLAINT, THIRD PARTY COMPLAINT, CROSS-CLAIM,
COUNTERCLAIM OR ANY ANSWER THERETO OR ANY AMENDMENT TO ANY OF THE
ABOVE TO SUBMIT TO BINDING ARBITRATION ALL CLAIMS, DISPUTES AND
CONTROVERSIES BETWEEN OR AMONG THEM (AND THEIR RESPECTIVE
EMPLOYEES, OFFICERS, DIRECTORS, ATTORNEYS, AND OTHER AGENTS),
WHETHER IN TORT, CONTRACT OR OTHERWISE ARISING OUT OF OR RELATING
IN ANY WAY TO THIS GUARANTY AND ITS NEGOTIATION, EXECUTION,
COLLATERALIZATION, ADMINISTRATION, REPAYMENT, MODIFICATION,
EXTENSION, SUBSTITUTION, FORMATION, INDUCEMENT, ENFORCEMENT,
DEFAULT OR TERMINATION; PROVIDED HOWEVER THAT THE PARTIES AGREE
THAT, NOTWITHSTANDING THE FOREGOING, EACH PARTY RETAINS THE RIGHT
TO PURSUE IN SMALL CLAIMS COURT ANY DISPUTE WITHIN THAT
COURT’S JURISDICTION. IN THE EVENT OF A COURT ORDERED
ARBITRATION, THE PARTY REQUESTING ARBITRATION SHALL BE RESPONSIBLE
FOR TIMELY FILING THE DEMAND FOR ARBITRATION AND PAYING THE
APPROPRIATE FILING FEE WITHIN THE 30 DAYS OF THE ABATEMENT ORDER OR
THE TIME SPECIFIED BY THE COURT. FAILURE TO TIMELY FILE THE DEMAND
FOR ARBITRATION AS ORDERED BY THE COURT WILL RESULT IN THAT
PARTY’S RIGHT TO DEMAND ARBITRATION BEING AUTOMATICALLY
TERMINATED.

 

(b) GOVERNING RULES. ANY
ARBITRATION PROCEEDING WILL (I) PROCEED IN A LOCATION IN THE
APPLICABLE STATE (AS DEFINED ABOVE) SELECTED BY THE AMERICAN
ARBITRATION ASSOCIATION (“AAA”); (II) BE GOVERNED
BY THE FEDERAL ARBITRATION ACT (TITLE 9 OF THE UNITED STATES CODE),
NOTWITHSTANDING ANY CONFLICTING CHOICE OF LAW PROVISION IN ANY OF
THE DOCUMENTS BETWEEN THE PARTIES; AND (III) BE CONDUCTED BY THE
AAA, OR SUCH OTHER ADMINISTRATOR AS THE PARTIES SHALL MUTUALLY
AGREE UPON, IN ACCORDANCE WITH THE AAA’S COMMERCIAL DISPUTE
RESOLUTION PROCEDURES, UNLESS THE CLAIM OR COUNTERCLAIM IS AT LEAST
$1,000,000.00 EXCLUSIVE OF CLAIMED INTEREST, ARBITRATION FEES AND
COSTS IN WHICH CASE THE ARBITRATION SHALL BE CONDUCTED IN
ACCORDANCE WITH THE AAA’S OPTIONAL PROCEDURES FOR LARGE,
COMPLEX COMMERCIAL DISPUTES (THE COMMERCIAL DISPUTE RESOLUTION
PROCEDURES OR THE OPTIONAL PROCEDURES FOR LARGE, COMPLEX COMMERCIAL
DISPUTES TO BE REFERRED TO HEREIN, AS APPLICABLE, AS THE
“RULES”). IF THERE IS ANY
INCONSISTENCY BETWEEN THE TERMS HEREOF AND THE RULES, THE TERMS AND
PROCEDURES SET FORTH HEREIN SHALL CONTROL. ANY PARTY WHO FAILS OR
REFUSES TO SUBMIT TO ARBITRATION FOLLOWING A DEMAND BY ANY OTHER
PARTY SHALL BEAR ALL COSTS AND EXPENSES INCURRED BY SUCH OTHER
PARTY IN COMPELLING ARBITRATION OF ANY DISPUTE.

 

(c) NO WAIVER OF PROVISIONAL REMEDIES,
SELF-HELP AND FORECLOSURE. THE ARBITRATION REQUIREMENT DOES
NOT LIMIT THE RIGHT OF ANY PARTY BEFORE, DURING OR AFTER THE
PENDENCY OF ANY ARBITRATION PROCEEDING TO (I) FORECLOSE AGAINST
REAL OR PERSONAL PROPERTY COLLATERAL; (II) EXERCISE SELF-HELP
REMEDIES RELATING TO COLLATERAL OR PROCEEDS OF COLLATERAL SUCH AS
SETOFF OR REPOSSESSION; OR (III) OBTAIN PROVISIONAL OR ANCILLARY
REMEDIES SUCH AS REPLEVIN, WRIT OF POSSESSION, INJUNCTIVE RELIEF,
ATTACHMENT, GARNISHMENT OR THE APPOINTMENT OF A RECEIVER. THIS
EXCLUSION DOES NOT CONSTITUTE A WAIVER OF THE RIGHT OR OBLIGATION
OF ANY PARTY TO SUBMIT ANY DISPUTE TO ARBITRATION OR REFERENCE
HEREUNDER, INCLUDING THOSE ARISING FROM THE EXERCISE OF THE ACTIONS
DETAILED IN SECTIONS (I), (II) AND (III) OF THIS
PARAGRAPH.

 

(d) ARBITRATOR QUALIFICATIONS AND
POWERS. ANY ARBITRATION PROCEEDING IN WHICH THE AMOUNT IN
CONTROVERSY IS $5,000,000.00 OR LESS WILL BE DECIDED BY A SINGLE
ARBITRATOR SELECTED ACCORDING TO THE RULES, AND WHO SHALL NOT
RENDER AN AWARD OF GREATER THAN $5,000,000.00. ANY DISPUTE IN WHICH
THE AMOUNT IN CONTROVERSY EXCEEDS $5,000,000.00 SHALL BE DECIDED BY
MAJORITY VOTE OF A PANEL OF THREE ARBITRATORS; PROVIDED HOWEVER,
THAT ALL THREE ARBITRATORS MUST ACTIVELY PARTICIPATE IN ALL
HEARINGS AND DELIBERATIONS, EXCEPT THAT A SINGLE ARBITRATOR MAY
DECIDE PRE-HEARING DISCOVERY DISPUTES. THE ARBITRATOR(S) WILL BE A
NEUTRAL ATTORNEY LICENSED IN THE APPLICABLE STATE (AS DEFINED
ABOVE) OR A NEUTRAL RETIRED JUDGE OF THE STATE OR FEDERAL JUDICIARY
OF THE APPLICABLE STATE (AS DEFINED ABOVE), IN EITHER CASE WITH A
MINIMUM OF TEN YEARS EXPERIENCE IN THE SUBSTANTIVE LAW APPLICABLE
TO THE SUBJECT MATTER OF THE DISPUTE TO BE ARBITRATED. THE
ARBITRATOR(S) WILL DETERMINE WHETHER OR NOT AN ISSUE IS
ARBITRATABLE AND WILL GIVE EFFECT TO THE STATUTES OF LIMITATION OR
REPOSE IN DETERMINING ANY CLAIM. IN ANY ARBITRATION PROCEEDING THE
ARBITRATOR(S) WILL DECIDE (BY DOCUMENTS ONLY OR WITH A HEARING AT
THE ARBITRATOR'S DISCRETION) ANY PRE-HEARING MOTIONS WHICH ARE
SIMILAR TO MOTIONS TO DISMISS FOR FAILURE TO STATE A CLAIM OR
MOTIONS FOR SUMMARY ADJUDICATION. THE ARBITRATOR(S) SHALL RESOLVE
ALL DISPUTES IN ACCORDANCE WITH THE SUBSTANTIVE LAW OF THE
APPLICABLE STATE (AS DEFINED ABOVE) AND MAY GRANT ANY REMEDY OR
RELIEF THAT A COURT OF SUCH STATE COULD ORDER OR GRANT WITHIN THE
SCOPE HEREOF AND SUCH ANCILLARY RELIEF AS IS NECESSARY TO MAKE
EFFECTIVE ANY AWARD. THE ARBITRATOR(S) SHALL ALSO HAVE THE POWER TO
AWARD RECOVERY OF ALL COSTS AND FEES, TO IMPOSE SANCTIONS AND TO
TAKE SUCH OTHER ACTION AS THE ARBITRATOR(S) DEEMS NECESSARY TO THE
SAME EXTENT A JUDGE COULD PURSUANT TO THE FEDERAL RULES OF CIVIL
PROCEDURE, THE APPLICABLE STATE’S (AS DEFINED ABOVE) RULES OF
CIVIL PROCEDURE OR OTHER APPLICABLE LAW. JUDGMENT UPON THE AWARD
RENDERED BY THE ARBITRATOR(S) MAY BE ENTERED IN ANY COURT HAVING
JURISDICTION. THE INSTITUTION AND MAINTENANCE OF AN ACTION FOR
JUDICIAL RELIEF OR PURSUIT OF A PROVISIONAL OR ANCILLARY REMEDY
SHALL NOT CONSTITUTE A WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING
THE PLAINTIFF, TO SUBMIT THE CONTROVERSY OR CLAIM TO ARBITRATION IF
ANY OTHER PARTY CONTESTS SUCH ACTION FOR JUDICIAL
RELIEF.

 

(e) DISCOVERY. IN ANY ARBITRATION
PROCEEDING, DISCOVERY WILL BE PERMITTED IN ACCORDANCE WITH THE
RULES. ALL DISCOVERY SHALL BE EXPRESSLY LIMITED TO MATTERS DIRECTLY
RELEVANT TO THE DISPUTE BEING ARBITRATED AND MUST BE COMPLETED NO
LATER THAN 20 DAYS BEFORE THE HEARING DATE. ANY REQUESTS FOR AN
EXTENSION OF THE DISCOVERY PERIODS, OR ANY DISCOVERY DISPUTES, WILL
BE SUBJECT TO FINAL DETERMINATION BY THE ARBITRATOR(S) UPON A
SHOWING THAT THE REQUEST FOR DISCOVERY IS ESSENTIAL FOR THE PARTY'S
PRESENTATION AND THAT NO ALTERNATIVE MEANS FOR OBTAINING
INFORMATION IS AVAILABLE.

 

(f) CLASS PROCEEDINGS AND
CONSOLIDATIONS. NO PARTY HERETO SHALL BE ENTITLED TO JOIN OR
CONSOLIDATE DISPUTES BY OR AGAINST OTHERS IN ANY ARBITRATION,
EXCEPT PARTIES WHO HAVE EXECUTED THIS GUARANTY OR ANY OTHER
CONTRACT, INSTRUMENT OR DOCUMENT RELATED TO THE OBLIGATIONS, OR TO
INCLUDE IN ANY ARBITRATION ANY DISPUTE AS A REPRESENTATIVE OR
MEMBER OF A CLASS, OR TO ACT IN ANY ARBITRATION IN THE INTEREST OF
THE GENERAL PUBLIC OR IN A PRIVATE ATTORNEY GENERAL
CAPACITY.

 

(g) PAYMENT OF ARBITRATION COSTS AND
FEES. THE ARBITRATOR(S) SHALL AWARD ALL COSTS AND EXPENSES
OF THE ARBITRATION PROCEEDING.

 

(h) MISCELLANEOUS. TO THE MAXIMUM
EXTENT PRACTICABLE, THE AAA, THE ARBITRATOR(S) AND THE PARTIES
SHALL TAKE ALL ACTION REQUIRED TO CONCLUDE ANY ARBITRATION
PROCEEDING WITHIN 180 DAYS OF THE FILING OF THE DISPUTE WITH THE
AAA. NO ARBITRATOR(S) OR OTHER PARTY TO AN ARBITRATION PROCEEDING
MAY DISCLOSE THE EXISTENCE, CONTENT OR RESULTS THEREOF, EXCEPT FOR
DISCLOSURES OF INFORMATION BY A PARTY REQUIRED IN THE CONNECTION
WITH FINANCIAL REPORTING IN THE ORDINARY COURSE OF ITS BUSINESS OR
BY APPLICABLE LAW OR REGULATION. IF MORE THAN ONE AGREEMENT FOR
ARBITRATION BY OR BETWEEN THE PARTIES POTENTIALLY APPLIES TO A
DISPUTE, THE ARBITRATION PROVISION MOST DIRECTLY RELATED TO THE
SUBJECT MATTER OF THE DISPUTE SHALL CONTROL. THIS ARBITRATION
PROVISION SHALL SURVIVE TERMINATION, AMENDMENT OR EXPIRATION OF
THIS GUARANTY OR ANY RELATIONSHIP BETWEEN THE PARTIES.

 

(i) WAIVER OF JURY TRIAL. THE
PARTIES HERETO HEREBY ACKNOWLEDGE THAT BY AGREEING TO BINDING
ARBITRATION THEY HAVE IRREVOCABLY WAIVED THEIR RESPECTIVE RIGHTS TO
A JURY TRIAL WITH RESPECT TO ANY ACTION, CLAIM OR OTHER PROCEEDING
ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS GUARANTY OR ANY
OTHER AGREEMENT OR DOCUMENT DELIVERED IN CONNECTION HEREWITH, ANY
RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE
OF SUCH RIGHTS AND OBLIGATIONS. THIS PROVISION IS A MATERIAL
INDUCEMENT FOR THE PARTIES ENTERING INTO THIS
AGREEMENT.

 

21. Counterparts;
Facsimile Execution. This Guaranty may be executed in any
number of duplicate originals or counterparts, each of which shall
be deemed to be an original and all taken together shall constitute
but one and the same instrument. Guarantor agrees that a facsimile
or electronic transmission of any signature of Guarantor shall be
effective as an original signature thereof. WFB agrees that a
facsimile or electronic transmission of this Guaranty executed by
WFB shall be effective as an original signature thereof. Any party
delivering an executed counterpart of this Guaranty by facsimile or
electronic transmission also shall deliver an original executed
counterpart of this Guaranty but the failure to deliver an original
executed counterpart shall not affect the validity, enforceability,
and binding effect of this Guaranty.

 

22. Agreement to be
Bound. Guarantor hereby agrees to be bound by each and all
of the terms and provisions of the Account Purchase Agreement
applicable to Guarantor. Without limiting the generality of the
foregoing, by its execution and delivery of this Guaranty,
Guarantor hereby: (a) makes to WFB each of the representations
and warranties set forth in the Account Purchase Agreement
applicable to Guarantor fully as though Guarantor were a party
thereto, and such representations and warranties are incorporated
herein by this reference, mutatis
mutandis; and (b) agrees and covenants (i) to do
each of the things set forth in the Account Purchase Agreement that
Client agrees and covenants to cause Guarantor to do, and
(ii) to not do any of the things set forth in the Account
Purchase Agreement that Client agrees and covenants to cause
Guarantor not to do, in each case, fully as though Guarantor was a
party thereto, and such agreements and covenants are incorporated
herein by this reference, mutatis
mutandis.

 FOURTH SUPPLEMENTAL INDENTURE, dated as of September 29, 2017 (the “Fourth
Supplemental Indenture”), among United Continental Holdings, Inc. (“UAL” or the “Issuer”), United Airlines, Inc. (“United”) and The Bank of New York Mellon Trust
Company, N.A., as trustee (the “Trustee”), to the Indenture, dated as of May 7, 2013 (the “Original Indenture”), among UAL, United and the Trustee. The Original Indenture as supplemented by this
Fourth Supplemental Indenture is hereinafter called the “Indenture.” 
 WHEREAS, Section 9.01 of the Original
Indenture permits supplements thereto to establish the form or terms of Securities pursuant to Article II of the Original Indenture; and 

WHEREAS, as contemplated by Section 2.02 of the Original Indenture, UAL wishes to establish the terms of a new Series of Securities (the
“Notes”) pursuant to this Fourth Supplemental Indenture. 
 NOW, THEREFORE, this Fourth Supplemental Indenture
witnesseth: 
 Section 1. Defined Terms. For purposes of this Fourth Supplemental Indenture, all terms defined in the Original
Indenture and used herein have such defined meanings unless otherwise defined herein. In addition, Section 7 hereof sets forth certain defined terms for purposes of this Fourth Supplemental Indenture. 

Section 2. Relation to Original Indenture. The Original Indenture is supplemented and modified as set forth in this Fourth
Supplemental Indenture for purposes of the Notes. This Fourth Supplemental Indenture shall not affect any Series of Securities other than the Notes. 

Section 3. Terms of the Notes. The terms of the Notes shall be as follows: 

3.1 Issuer. The issuer of the Notes shall be UAL. 

3.2 Title and Form. The title of the Notes is 4.25% Senior Notes due 2022. The Notes shall be in registered form and in substantially
the form attached hereto as Exhibit A. 
 3.3 Aggregate Principal Amount. The aggregate principal amount of the Notes which
may be authenticated and delivered under the Indenture is initially limited to $400,000,000, except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Notes, and subject to increase as
set forth in Section 3.15 hereof. 
 3.4 Principal Payment. The outstanding principal amount of the Notes shall be due and
payable on October 1, 2022. 
 3.5 Interest. The outstanding principal amount of the Notes shall bear interest at the rate of
4.25% per annum, payable in arrears on April 1 and October 1 of each year (each, an “Interest Payment Date”), commencing on April 1, 2018, to the Persons in whose names the Notes are registered at the close of
business on the March 15 and September 15, respectively, next preceding such Interest Payment Date (each, a “Regular Record Date”). Interest shall accrue from the most recent date to which interest has been paid or
for which interest has been 

  
 1 

 
provided, or, if no interest has been paid or provided for, from September 29, 2017. Interest due on any date shall be the amount accrued to but excluding such due date. Interest shall be
calculated on the basis of a 360-day year of twelve 30-day months. Any payment required to be made on any day that is not a Business Day will be made on the next
succeeding Business Day without any interest or other payment due to the delay. 
 3.6 Method of Payment. Principal of, premium (if
any) and interest on the Notes shall be payable as provided in Section 2.15 of the Original Indenture. Notwithstanding the foregoing, payments of principal of, premium (if any) and interest on the Notes represented by one or more Global Notes
will be made as provided in Section 3.8 hereof. 
 3.7 Optional Redemption. The Issuer, at its option, may redeem the Notes in
whole at any time or in part from time to time, at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of
principal and interest on such Notes (excluding accrued and unpaid interest to the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points, plus, in case of either the preceding clause (1) or (2), accrued and unpaid interest on the principal amount being redeemed to such
redemption date. Article III of the Original Indenture shall apply to any such redemption, except that the third sentence of Section 3.02 of the Original Indenture shall be amended to read as follows: “Notes and portions thereof that
the Trustee selects shall be in principal amounts of $2,000 or integral multiples of $1,000 in excess thereof.” If less than all outstanding Notes are to be redeemed, any selection of Notes to be redeemed shall be subject to applicable
procedures of The Depository Trust Company (“DTC”) so long as it is the Depositary. For purposes of any redemptions pursuant to this Section 3.7, the following terms shall have the respective specified meanings: 

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent
as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of such Notes. 
 “Comparable Treasury Price” means, with respect to
any redemption date for Notes, the average of two Reference Treasury Dealer Quotations for such redemption date. 

“Quotation Agent” means the Reference Treasury Dealer appointed by the Issuer. 

“Reference Treasury Dealer” means each of Morgan Stanley & Co. LLC and Credit Suisse
Securities (USA) LLC, and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary United States Government securities dealer in New York City (a “Primary Treasury Dealer”), the
Issuer will substitute therefor another Primary Treasury Dealer. 

  
 2 

 “Reference Treasury Dealer Quotations” means, with
respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Issuer, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Issuer by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date. 

“Treasury Rate” means, with respect to any redemption date, (1) the yield to
maturity calculated by taking the simple average of the yields to maturity for the applicable Comparable Treasury Issue for each of the five Business Days immediately preceding the third Business Day before the calculation date as reported on the
most recent H.15 page available through the website of the Board of Governors of the Federal Reserve System at http://www.federalreserve.gov/releases/h15/update, or any successor site or publication, for the applicable Comparable Treasury Issue and
which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity
is within three months before or after the maturity date of the Notes to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined, and the Treasury Rate shall be
interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or (2) if such report (or any successor site or publication) is not available during any of such five Business Days or does not contain such
yields, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable
Treasury Price for such redemption date. The Treasury Rate will be calculated on the third Business Day preceding the redemption date. 

3.8 Global Notes. The Notes shall initially be issued in the form of one or more Global Securities registered in the name of DTC, which
shall be the initial Depositary with respect to the Notes, or its nominee (a “Global Note”), which shall be delivered to the Trustee as custodian for the Depositary or its nominee. The Paying Agent shall make payments of
principal, premium, if any, or interest due on the Notes represented by one or more Global Notes to the Depositary or its nominee, as the case may be, as the registered owner of the related Global Note or Global Notes, by wire transfer of
immediately available funds to the account designated by such registered holder. 
 3.9 Legends on Notes. 

(a) In addition to the legend set forth in Section 2.14(c) of the Original Indenture, so long as DTC is the Depositary, each Global Note
registered in the name of DTC or its nominee shall bear a legend in substantially the following form: 
 “UNLESS THIS GLOBAL NOTE IS
PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK 

  
 3 

 
CORPORATION (“DTC”), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY GLOBAL NOTE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH
OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.” 
 (b)
All Notes shall bear a legend substantially in the following form: 
 “BY ACCEPTANCE OF THIS NOTE OR ANY INTEREST HEREIN, EACH
PURCHASER AND SUBSEQUENT TRANSFEREE OF THIS NOTE OR ANY INTEREST HEREIN WILL BE DEEMED TO HAVE REPRESENTED AND WARRANTED TO THE ISSUER AND THE TRUSTEE THAT EITHER (I) SUCH PURCHASER OR TRANSFEREE IS NOT AN EMPLOYEE BENEFIT PLAN THAT IS SUBJECT
TO TITLE I OF THE EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (“ERISA”), A PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT THAT IS SUBJECT TO SECTION 4975 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE
“CODE”), OR PROVISIONS UNDER ANY FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR REGULATIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF THE CODE OR ERISA (COLLECTIVELY, “SIMILAR LAWS”), OR AN
ENTITY WHOSE UNDERLYING ASSETS ARE CONSIDERED TO INCLUDE “PLAN ASSETS” OF SUCH PLANS, ACCOUNTS AND ARRANGEMENTS (COLLECTIVELY, “PLANS”), AND NO PORTION OF THE ASSETS USED BY SUCH PURCHASER OR TRANSFEREE TO ACQUIRE AND HOLD THIS
NOTE OR ANY INTEREST HEREIN CONSTITUTES ASSETS OF ANY PLAN OR (II) THE PURCHASE AND HOLDING OF THIS NOTE OR ANY INTEREST HEREIN BY SUCH PURCHASER OR TRANSFEREE WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED
TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A VIOLATION OF ANY APPLICABLE SIMILAR LAW.” 
 3.10 Note
Denominations. The Notes shall be issued in denominations of $2,000 or an integral multiple of $1,000 in excess thereof. 
 3.11 No
Sinking Fund. The Notes will not be entitled to the benefit of any sinking fund. 
 3.12 Indenture Covenants. The covenants set
forth in Article IV and Article V of the Original Indenture shall apply to the Notes. 
 3.13 Note Guarantee. United (the
“Guarantor”) fully and unconditionally guarantees the Notes pursuant to Article X of the Original Indenture (the “Note Guarantee”). The Notation of Note Guarantee substantially in the form
attached hereto as Exhibit B shall be executed by United and attached to each Note authenticated pursuant to the Indenture. 

  
 4 

 3.14 Amendments. 

(a) Section 9.01(1) of the Original Indenture shall be amended to insert the following at the end thereof: 

“, or to evidence the succession of another Person to the Guarantor pursuant to Section 10.04 and the assumption by such successor of
the Guarantor’s covenants, agreements and obligations in this Indenture and with respect to the Securities;” 
 (b)
    Section 9.02(7) of the Original Indenture shall be amended and restated to read as follows: 
 “except as
provided under Article VIII hereof or in connection with a consolidation, merger or conveyance, transfer or lease of assets pursuant to this Indenture, release any Securities Guarantor from any of its obligations under its Securities Guarantee or
make any change in a Securities Guarantee that would adversely affect such Holder; or” 
 3.15 Further Issuances. The Issuer
may, from time to time, without notice to or the consent of the Holders of the Notes, increase the principal amount of the Notes under the Indenture and issue such increased principal amount (or any portion thereof), in which case any additional
Notes so issued will have the same form and terms (other than the date of issuance and, under certain circumstances, the date from which interest thereon will begin to accrue), and will carry the same right to receive accrued and unpaid interest, as
the Notes previously issued, and such additional Notes will form a single series with the Notes.  
 3.16 No Reissuance of
Notes. The Issuer may not reissue a Note that has matured, been redeemed, been purchased by the Issuer at the Holder’s option upon a Change of Control or otherwise been canceled, except for registration of transfer, exchange or replacement
of such Note. 
 Section 4. Additional Covenants Applicable to the Notes. The following covenants shall be applicable for
purposes of the Notes: 
 4.1 Offer to Repurchase Upon Change of Control. 

(a) Upon the occurrence of a Change of Control, each Holder of Notes shall have the right to require the Issuer to repurchase all or any part
(equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to an offer (a “Change of Control Offer”) at a purchase price in cash equal to 101% of the aggregate principal amount
of Notes repurchased, plus accrued and unpaid interest on the Notes repurchased to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant Record Date to receive
interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Issuer shall mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and stating: 

(1)    that the Change of Control Offer is being made pursuant to this Section 4.1 and that all Notes
tendered will be accepted for payment; 

  
 5 

 (2)    the purchase price and the purchase date, which shall
be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”); 

(3)    that any Note not tendered will continue to accrue interest; 

(4)    that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted
for payment pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 

(5)    that Holders of Notes electing to have any Notes purchased pursuant to a Change of Control Offer
will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer such Notes by book-entry transfer, to the Paying Agent at the address specified in the notice
prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 

(6)    that Holders of Notes will be entitled to withdraw their election if the Paying Agent receives, not
later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase,
and a statement that such Holder is withdrawing its election to have the Notes purchased; and 

(7)    that Holders of Notes whose Notes are being purchased only in part will be issued new Notes equal in
principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof. 

The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and
any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws
or regulations conflict with the provisions of this Section 4.1, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.1 by virtue of such
compliance. The Issuer will provide a copy of such notice to the Trustee. 
 (b) On the Change of Control Payment Date, the Issuer will, to
the extent lawful: 
 (1)    accept for payment all Notes or portions of Notes properly tendered pursuant
to the Change of Control Offer; 
 (2)    deposit with the Paying Agent an amount equal to the Change of
Control Payment in respect of all Notes or portions of Notes properly tendered; and 

  
 6 

 (3)    deliver or cause to be delivered to the Trustee the
Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Issuer. 

The Paying Agent will promptly mail (or pay by wire transfer) (but in any case not later than five days after the Change of
Control Payment Date) to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Issuer shall issue, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each such
Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any. The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment
Date. 
 (c) Notwithstanding anything to the contrary in this Indenture or the Notes: 

(1)    the Issuer shall not be required to make a Change of Control Offer upon a Change of Control if
(1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.1 and purchases all Notes properly tendered and not withdrawn under the Change of
Control Offer or (2) notice of redemption with respect to all Notes has been given pursuant to Section 3.01 of the Indenture, unless and until there is a default in payment of the applicable redemption price; and 

(2)    a Change of Control Offer may be made in advance of a Change of Control, conditioned upon the
consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made. 

(d) For the avoidance of doubt, the Issuer’s failure to make a Change of Control Offer would constitute a Default under clause
(3) of Section 6.01 of the Indenture and not clause (1) or (2) thereof, but the failure of the Issuer to pay the Change of Control Payment when due shall constitute a Default under clause (1) of Section 6.01 thereof. 

4.2 Restricted Payments. 

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly: 

(1)    declare or pay any dividend or make any other payment or distribution on account of the
Issuer’s or any of its Restricted Subsidiaries’ Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Issuer or any of its Restricted Subsidiaries) or to the direct or
indirect holders of the Issuer’s or any of its Restricted Subsidiaries’ Equity Interests in their capacity as such (other than (A) dividends, distributions or payments payable in Qualifying Equity Interests or, in the case of
preferred stock of the Issuer, an increase in the liquidation value thereof and (B) dividends, distributions or payments payable to the Issuer or a Restricted Subsidiary of the Issuer);

redeem, defease or otherwise acquire or retire for value (collectively for purposes of this clause (3), a “purchase”) any Indebtedness of the Issuer or the Guarantor that is contractually subordinated to the Notes or the Note Guarantee
(excluding any intercompany Indebtedness between or among the Issuer and any of its Restricted Subsidiaries), except any scheduled payment of interest and any purchase within two years of the Scheduled Maturity thereof; or 

(4)    make any Restricted Investment (all such payments and other actions set forth in these clauses
(1) through (4) above being collectively referred to as “Restricted Payments”), 
 unless, at
the time of and after giving effect to such Restricted Payment: 
  

	 	(i)	no Default has occurred and is continuing; 

  

	 	(ii)	the Issuer would, at the time of such Restricted Payment and after giving pro forma effect thereto as if such Restricted Payment had been made at the beginning of the applicable four-quarter period, have been permitted
to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio test set forth in Section 4.3(a) hereof; and 

(iii)    such Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Issuer
and its Restricted Subsidiaries since the Closing Date (excluding Restricted Payments permitted by clauses (2) through (20) of Section 4.2(b) hereof) is less than the sum, without duplication, of: 

(A)    50% of the Consolidated Net Income of the Issuer for the period (taken as one accounting period) from July 1,
2011, to the end of the Issuer’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted Payment (or, if such Consolidated Net Income for such period is a deficit, less 100% of
such deficit); plus 
 (B)    100% of the aggregate net cash proceeds and the Fair Market Value of non-cash consideration received by the Issuer since May 7, 2013 as a contribution to its common equity capital or from the issue or sale of Qualifying Equity Interests (other than Qualifying Equity Interests
sold to a Subsidiary of the Issuer and excluding Excluded Contributions); plus 

  
 8 

 (C)    100% of the aggregate net cash proceeds and the Fair Market Value of non-cash consideration received by the Issuer or a Restricted Subsidiary of the Issuer from the issue or sale of convertible or exchangeable Disqualified Stock of the Issuer or a Restricted Subsidiary of the Issuer
or convertible or exchangeable debt securities of the Issuer or a Restricted Subsidiary of the Issuer (regardless of when issued or sold) or in connection with the conversion or exchange thereof, in each case that have been converted into or
exchanged since May 7, 2013 for Qualifying Equity Interests (other than Qualifying Equity Interests and convertible or exchangeable Disqualified Stock or debt securities sold to a Subsidiary of the Issuer); plus 

(D)    to the extent that any Restricted Investment that was made after May 7, 2013 (other than in reliance on clause
(16) of Section 4.2(b) hereof) is (i) sold for cash or otherwise cancelled, liquidated or repaid for cash or (ii) made in an entity that subsequently becomes a Restricted Subsidiary of the Issuer, the initial amount of such
Restricted Investment (or, if less, the amount of cash received upon repayment or sale); plus 
 (E)    to the extent
that any Unrestricted Subsidiary of the Issuer designated as such after the Closing Date is redesignated as a Restricted Subsidiary after the Closing Date, the lesser of (i) the Fair Market Value of the Issuer’s Restricted Investment in
such Subsidiary (made other than in reliance on clause (16) of Section 4.2(b) hereof) as of the date of such redesignation or (ii) such Fair Market Value as of the date on which such Subsidiary was originally designated as an
Unrestricted Subsidiary after the Closing Date; plus 
 (F)    100% of any dividends received in cash by the Issuer or a
Restricted Subsidiary of the Issuer after May 7, 2013 from an Unrestricted Subsidiary of the Issuer, to the extent that such dividends were not otherwise included in the Consolidated Net Income of the Issuer for such period. 

(b) The provisions of Section 4.2(a) hereof will not prohibit: 

(1)    the payment of any dividend or distribution or the consummation of any irrevocable redemption within
60 days after the date of declaration of the dividend or distribution or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or redemption payment would have complied with the provisions of the
Indenture; 
 (2)    the making of any Restricted Payment in exchange for, or out of or with the net cash
proceeds of the substantially concurrent sale (other than to a 

  
 9 

 
Subsidiary of the Issuer) of, Qualifying Equity Interests or from the substantially concurrent contribution of common equity capital to the Issuer; provided that the amount of any such net cash
proceeds that are utilized for any such Restricted Payment will not be considered to be net proceeds of Qualifying Equity Interests for purposes of Section 4.2(a)(iii)(B) hereof and will not be considered to be Excluded Contributions; 

(3)    the payment of any dividend (or, in the case of any partnership or limited liability company, any
similar distribution), distribution or payment by a Restricted Subsidiary of the Issuer to the holders of its Equity Interests on a pro rata basis; 

(4)    the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness
of the Issuer or the Guarantor that is contractually subordinated to the Notes or to the Note Guarantee with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness; 

(5)    the repurchase, redemption, acquisition or retirement for value of any Equity Interests of the
Issuer or any Restricted Subsidiary of the Issuer held by any current or former officer, director, consultant or employee (or their estates or beneficiaries of their estates) of the Issuer or any of its Restricted Subsidiaries pursuant to any
management equity plan or equity subscription agreement, stock option agreement, shareholders’ agreement or similar agreement; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall
not exceed $50.0 million in any twelve-month period (except to the extent such repurchase, redemption, acquisition or retirement is in connection with (x) the acquisition of a Permitted Business or merger, consolidation or amalgamation
otherwise permitted by the Indenture and in such case the aggregate price paid by the Issuer and its Restricted Subsidiaries shall not exceed $100.0 million in connection with such acquisition of a Permitted Business or merger, consolidation or
amalgamation or (y) the Continental/UAL Merger, in which case no dollar limitation shall be applicable); provided further, that the Issuer or any of its Restricted Subsidiaries may carry over and make in subsequent twelve-month periods, in
addition to the amounts permitted for such twelve-month period, up to $25.0 million of unutilized capacity under this clause (5) attributable to the immediately preceding twelve-month period; 

(6)    the repurchase of Equity Interests or other securities deemed to occur upon (A) the exercise of
stock options, warrants or other securities convertible or exchangeable into Equity Interests or any other securities, to the extent such Equity Interests or other securities represent a portion of the exercise price of those stock options, warrants
or other securities convertible or exchangeable into Equity Interests or any other securities or (B) the withholding of a portion of Equity Interests issued to employees and other participants under an equity compensation program of the Issuer
or its Subsidiaries to cover withholding tax obligations of such persons in respect of such issuance; 

  
 10 

 (7)    so long as no Default has occurred and is continuing,
the declaration and payment of regularly scheduled or accrued dividends, distributions or payments to holders of any class or series of Disqualified Stock or subordinated debt of the Issuer or any preferred stock of any Restricted Subsidiary of the
Issuer in each case either outstanding on the Closing Date or issued on or after the Closing Date in accordance with Section 4.3 hereof;

(C) the conversion or exchange of Indebtedness or hybrid securities into Capital Stock of any such Person; 

(9)    the declaration and payment of dividends to holders of any class or series of Disqualified Stock of
the Issuer or any Disqualified Stock or preferred stock of any Restricted Subsidiary of the Issuer to the extent such dividends are included in the definition of “Fixed Charges” for such Person; 

(10)    in the event of a Change of Control, and if no Default shall have occurred and be continuing, the
payment, purchase, redemption, defeasance or other acquisition or retirement of any subordinated Indebtedness of the Issuer or the Guarantor, in each case, at a purchase price not greater than 101% of the principal amount of such subordinated
Indebtedness, plus any accrued and unpaid interest thereon; provided, however, that prior to such payment, purchase, redemption, defeasance or other acquisition or retirement, the Issuer or the Guarantor (or a third party to the extent permitted by
the Indenture) has made a Change of Control Offer as a result of such Change of Control (it being agreed that the Issuer or the Guarantor may pay, purchase, redeem, defease or otherwise acquire or retire such subordinated Indebtedness even if the
purchase price exceeds 101% of the principal amount of such subordinated Indebtedness; provided that the amount paid in excess of 101% of such principal amount is otherwise permitted under the Restricted Payments covenant); 

(11)    Restricted Payments made with Excluded Contributions; 

(12)    the distribution, as a dividend or otherwise, of shares of Capital Stock of, or Indebtedness owed
to the Issuer or any of its Restricted Subsidiaries by, any Unrestricted Subsidiary; 
 (13)    the
distribution or dividend of assets or Capital Stock of any Person in connection with any full or partial “spin-off” of a Subsidiary or similar transactions; provided that (i) the Issuer would,
on the date of such distribution after giving pro forma effect thereto as if the same had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Fixed Charge
Coverage Ratio test set forth in Section 4.3(a) hereof, (ii) such pro forma Fixed Charge Coverage Ratio 

  
 11 

 
referred to in the preceding clause (i) would be greater than or equal to such Fixed Charge Coverage Ratio immediately prior to such transaction or (iii) if such Subsidiary is not the
Guarantor, no Default has occurred and is continuing; 
 (14)    the distribution or dividend of assets
or Capital Stock of any Person in connection with any full or partial “spin-off” of a Subsidiary or similar transactions having an aggregate Fair Market Value not to exceed $500.0 million since
the Closing Date; 
 (15)    so long as no Default has occurred and is continuing, other Restricted
Payments in an aggregate amount not to exceed $1.0 billion, such aggregate amount to be calculated from the Closing Date;

restricted stock units or other instruments or rights whose value is based in whole or in part on the value of any Equity Interests issued to any directors, officers or employees of the Issuer or any Restricted Subsidiary of the Issuer;

or redeem Equity Interests of Issuer or (ii) consisting of payments in respect of any Indebtedness (whether for purchase or prepayment thereof or otherwise); 

(19)    any Restricted Payment so long as both before and after giving effect to such Restricted Payment,
Issuer and its Restricted Subsidiaries have Liquidity in the aggregate of at least $2.2 billion; and 

(20)    Restricted Payments in an aggregate amount which do not exceed 5.0% of the Consolidated Tangible
Assets of Issuer and its Restricted Subsidiaries (calculated at the time of such Restricted Payment). 
 (c)    In the
case of any Restricted Payment that is not cash, the amount of such non-cash Restricted Payment will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be
transferred or issued by the Issuer or such Restricted Subsidiary of the Issuer, as the case may be, pursuant to the Restricted Payment. 

(d)    For purposes of determining compliance with this Section 4.2, if a proposed Restricted Payment (or portion
thereof) meets the criteria of more than one of the categories of Restricted Payments set forth in clauses (1) through (20) of Section 4.2(b) hereof, or is entitled to be made pursuant to Section 4.2(a) hereof, the Issuer will be
entitled to classify on the date of its payment or later reclassify such Restricted Payment (or portion thereof) in any manner that complies with this Section 4.2. 

  
 12 

 (e)    For the avoidance of doubt, the following shall not constitute
Restricted Payments and therefore will not be subject to any of the restrictions set forth in this Section 4.2: 

(1)    the payment on or with respect to, or purchase, redemption, defeasance or other acquisition or
retirement for value of any Indebtedness of the Issuer or any Restricted Subsidiary of the Issuer that is not contractually subordinated to the Notes and the Note Guarantee; 

(2)    the payment of regularly scheduled amounts in respect of, and the issuance of common stock of the
Issuer upon conversion of, the 6% Convertible Preferred Securities, Term Income Deferred Equity Securities (TIDES)SM issued by Continental Airlines Finance Trust II or the underlying 6%
Convertible Junior Subordinated Debentures due 2030 issued by Continental; and 
 (3)    the conversion
of the Capital Stock of the Issuer or the Guarantor pursuant to the Airline/Parent Merger. 
 (f)    Notwithstanding
anything in this Indenture to the contrary, if a Restricted Payment is made at a time when a Default has occurred and is continuing and such Default is subsequently cured, the Default or Event of Default arising from the making of such Restricted
Payment during the existence of such Default shall simultaneously be deemed cured. 
 4.3 Incurrence of Indebtedness and Issuance of
Preferred Stock. 
 (a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, create,
incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and the Issuer will not issue
any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any shares of preferred stock; provided, however, that the Issuer may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock and its Restricted
Subsidiaries may incur Indebtedness (including Acquired Debt) or issue preferred stock, if the Issuer’s Fixed Charge Coverage Ratio for the most recently ended four full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or such preferred stock is issued, as the case may be, would have been at least 1.1 to 1.0, determined on a pro forma basis (including a pro
forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or the preferred stock had been issued, as the case may be, at the beginning of such four-quarter period. 

(b) The provisions of Section 4.3(a) hereof shall not prohibit the incurrence of any of the following items of Indebtedness

Guarantor of the Notes and the Note Guarantee in the aggregate principal amount to be issued on the Closing Date and any Permitted Refinancing Indebtedness that is incurred to renew, refund, refinance, replace, defease, extend or discharge any other

respect thereto) under Credit Facilities secured on a junior priority basis by some or all of the collateral securing Indebtedness under Credit Facilities contemplated by clause (A) of this clause (3) in an aggregate principal amount at
any one time outstanding under this clause (3)(B) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Issuer and its Restricted Subsidiaries thereunder) not to exceed $3.0 billion;

 (4)    the incurrence by the Issuer or any of its Restricted Subsidiaries of Indebtedness represented

in the business of the Issuer or any of its Restricted Subsidiaries; 
 (5)    the incurrence by the

Indebtedness secured by aircraft, airframes, engines, spare parts, flight simulators, flight training devices or other assets replacing, renewing, refunding, extending, refinancing, defeasing or discharging any other Indebtedness of the Issuer or

 For purposes of determining compliance with this Section 4.3, if an item of
Indebtedness meets the criteria of more than one of the categories of Permitted Debt set forth in clauses (1) through (25) of Section 4.3(b) hereof or is entitled to be incurred pursuant to Section 4.3(a) hereof, the Issuer will be
permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in any manner that complies with this Section 4.3; provided that (A) all “Junior Secured
Debt” (as defined in the Credit Agreement as in effect on the Closing Date) will at all times be deemed to have been incurred in reliance on the exception provided by Section 4.3(b)(21) hereof and (B) the term “Existing
Indebtedness” will not include any Indebtedness that is permitted to be incurred under clauses (1), (3) or (21) of Section 4.3(b) hereof. 

None of the following will constitute an incurrence of Indebtedness or an issuance of preferred stock or Disqualified Stock for purposes of
this Section 4.3: 
 (1)    the accrual of interest or preferred stock dividends; 

(2)    the accretion or amortization of original issue discount (“OID”); 

(3)    the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms; 

(4)    the reclassification of preferred stock as Indebtedness due to a change in accounting principles; and 

  
 17 

 (5)    the payment of dividends on preferred stock or Disqualified Stock in
the form of additional shares of the same class of preferred stock or Disqualified Stock. 
 For purposes of determining compliance with any
U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be utilized, calculated based on the relevant currency exchange rate in effect
on the date such Indebtedness was incurred. Notwithstanding any other provision of this Section 4.3, the maximum amount of Indebtedness that the Issuer or any of its Restricted Subsidiaries may incur pursuant to this Section 4.3 shall not
be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 The amount of any Indebtedness
outstanding as of any date will be: 
 (1)    the accreted value of the Indebtedness as of such date, in the case of any
Indebtedness issued with OID; 
 (2)    the principal amount of the Indebtedness as of such date, in the case of any
other Indebtedness; and 
 (3)    in respect of Indebtedness of another Person secured by a Lien on the assets of the
specified Person, the lesser of: 
 (A)    the Fair Market Value of such assets as of such date; and 

(B)    the amount of the Indebtedness of the other Person as of such date. 

4.4    Designation of Restricted and Unrestricted Subsidiaries. 

(a)    The Board of Directors may designate any Restricted Subsidiary of the Issuer (other than the Guarantor) to be an
Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Issuer and its Restricted
Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation. That designation will be permitted only if the Investment would be permitted at that time under
Section 4.2 hereof and if the Restricted Subsidiary otherwise meets the definition of an “Unrestricted Subsidiary.” 
 (b)
    Any designation of a Subsidiary of the Issuer as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors of the Issuer giving effect to
such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions. The Board of Directors of the Issuer may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of
the Issuer; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Issuer of any outstanding Indebtedness of such Unrestricted Subsidiary and such designation will be permitted only if
(i) such Indebtedness is permitted under Section 4.3 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the applicable reference period and (ii) no Default would be in existence following
such designation.

(B) appoints a Custodian of the Issuer, any of the Issuer’s Restricted Subsidiaries that is a Significant Subsidiary or

(5): 
 “(6)    except as permitted by the Indenture, the Note Guarantee is held in any judicial
proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or the Guarantor denies or disaffirms in writing its obligations under the Note Guarantee.” 

Section 6. Acceleration. Section 6.02 of the Original Indenture shall be amended and restated to read as follows: 

“Acceleration. If an Event of Default with respect to the Notes (other than an Event of Default specified in Section 6.01(4)
or (5) of the Indenture) occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes outstanding may, by written notice to the Issuer (and to the Trustee if such notice is given by the Holders), declare
the principal amount of, and accrued and unpaid interest on all the Notes to be due and payable. Upon such a declaration, such amounts shall be due and payable immediately. If an Event of Default specified in Section 6.01(4) or (5) of the
Indenture occurs, the principal amount of, and accrued and unpaid interest on all the Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders
of a majority in principal amount of the Notes by notice to the Trustee may rescind an acceleration of the Notes and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default with respect
to such Notes have been cured or waived except nonpayment of the principal amount of, and accrued and unpaid interest on all Notes that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair
any right consequent thereto.”

Calculation Date will be deemed to have been a Restricted Subsidiary at all times during such four-quarter period;

Subsidiary at any time during such four-quarter period; and 
 (6)    if any Indebtedness bears a floating rate of
interest, the interest expense on such Indebtedness will be calculated as if the rate in effect on the Calculation Date had been the applicable rate for the entire period (taking into account any Hedging Obligation applicable to such Indebtedness if

deemed to be an Investment. The acquisition by the Issuer or any Restricted Subsidiary of the Issuer after the Closing Date of a Person that holds an Investment in a third Person will be deemed to be an Investment by the Issuer or such Restricted
Subsidiary in such third Person in an amount equal to the Fair Market Value of the Investments held by the acquired Person in such third Person in an amount determined as provided in Section 4.2(c) hereof. Except as otherwise provided in the

 (REVERSE OF SECURITY) 

4.25% SENIOR NOTES DUE 2022 

(1)    Interest. United Continental Holdings, Inc., a Delaware corporation (the “Issuer”), shall pay
interest on the outstanding principal amount of this Note at a rate per annum of 4.25% (calculated on the basis of a 360-day year of twelve 30-day months), payable
semi-annually in arrears, on each Interest Payment Date until the principal thereof has been paid in full, commencing on April 1, 2018, to the Person in whose name this Note is registered at the close of business on the Record Date next
preceding such Interest Payment Date. Interest shall accrue on this Note from the most recent date to which interest on this Note has been paid or for which interest has been provided or, if no interest has been paid or provided for hereon, from
September 29, 2017. 
 (2)    Terms of Payment. Interest on the Notes which is payable, and is punctually
paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name the Note is registered at the close of business on the Record Date next preceding such Interest Payment Date at the office or agency of the Issuer
maintained for such purpose under the Indenture (as such term is defined below); provided, however, that each installment of interest on any Note may be paid at the Issuer’s option by mailing a check for such interest, payable to or upon the
written order of the Person entitled thereto, to the address of such Person as it appears on the register for such Note or by wire transfer of immediately available funds to an account of the Person entitled thereto as such account shall be provided
to the Registrar for such Notes and shall appear on the applicable register. Payments of principal (and premium, if any) of a Note shall be made against surrender of such Note at the office or agency of the Issuer maintained for such purpose
pursuant to the Indenture at the Issuer’s option by check payable to or upon the written order of the Person entitled thereto or by wire transfer to an account of the Person entitled thereto as such account shall be provided to the Registrar
for such Notes. All amounts payable by the Issuer with respect to the Notes shall be in U.S. dollars. 

(3)    Registrar and Paying Agent. Initially, The Bank of New York Mellon Trust Company, N.A., a national banking
association, not in its individual capacity but solely as trustee (the “Trustee”), will act as Paying Agent and Registrar for the Notes. The Issuer may remove any Paying Agent or Registrar without notice to the Holders. 

(4)    Indenture. The Issuer issued the Notes under the Indenture dated as of May 7, 2013 (the “Original
Indenture”), among (a) the Issuer, (b) United Airlines, Inc. (the “Guarantor”) and (c) the Trustee, as supplemented by the Fourth Supplemental Indenture, dated as of September 29, 2017 (the “Fourth
Supplemental Indenture”), among the Issuer, the Guarantor, and the Trustee (the Original Indenture, as supplemented by the Fourth Supplemental Indenture, the “Indenture”). This Note is one of a duly authorized series of notes of the
Issuer designated as its 4.25% Senior Notes due 2022. The Notes are initially limited in aggregate principal amount to $400,000,000. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the
Notes include those stated in the Indenture and made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the “TIA”), as in effect on the date of the Indenture.
Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the 

  
 1 

 
Indenture and the TIA for a statement of them. To the extent any provision of the Notes limits, qualifies or conflicts with another provision which is required to be included in the Indenture by
the TIA, the required provision shall control. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time. 

(5)    Optional Redemption; Change of Control Repurchase. 

(a)    The Notes will be redeemable, at the Issuer’s option, in whole at any time or in part from time to time,
pursuant to the terms of the Indenture at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and
interest on such Notes (excluding accrued and unpaid interest to the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 50 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to such redemption date. 

(b)    Upon the occurrence of a Change of Control, each Holder of Notes will have the right to require the Issuer to
repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of the Notes pursuant to a Change of Control Offer at a purchase price of 101% of the aggregate principal amount of the Notes repurchased, plus accrued
and unpaid interest on the Notes repurchased to the date of purchase. 
 (6)    Denominations; Transfer;
Exchange. The Notes shall be issuable in denominations of $2,000 or an integral multiple of $1,000 in excess thereof. Where Notes are presented to the Registrar with a request to register a transfer or to exchange them for an equal principal
amount of Notes, the Registrar shall register the transfer of or make the exchange if its requirements for such transactions are met. To permit registrations of transfers and exchanges, the Trustee shall authenticate the Notes at the
Registrar’s request. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted in the Indenture), but the Issuer may require the payment of a sum sufficient to cover any transfer tax
or similar governmental charge payable in connection therewith (other than with respect to exchanges of temporary securities, securities redeemed in part, or to amend the terms of a Note). Neither the Issuer nor the Registrar shall be required
(a) to register the transfer of, or exchange of any Notes for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of any Notes selected for redemption and ending at the close
of business on the day of such mailing or (b) to register the transfer of or exchange of any Notes selected, called or being called for redemption as a whole or the portion being redeemed of any such Notes selected, called or being called for
redemption in part. 
 (7)    Persons Deemed Owners. The Person in whose name a Note is registered shall be
treated as the owner of it for the purpose of receiving payment of principal of (and premium, if any) and interest, if any, on this Note and for all other purposes whatsoever. 

(8)    Unclaimed Money. Any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in
trust for the payment of principal of, or premium, if any, or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or 

  
 2 

 
interest has become due and payable shall be paid to the Issuer on its request or (if then held by the Issuer) shall be discharged from such trust. Thereafter, the Holder of such Note shall look
only to the Issuer for payment thereof, and all liability of the Trustee and such Paying Agent with respect to such money, and all liability of the Issuer as trustee thereof, shall cease. 

(9)    Satisfaction and Discharge Prior to Redemption or Stated Maturity. Subject to certain conditions, the Issuer
may terminate some or all of its obligations under the Notes and the Indenture if the Issuer deposits with the Trustee as trust funds in cash or non-callable Government Securities, or a combination thereof, in
an amount sufficient to pay the principal of, and premium if any, and interest on the Notes to redemption or Stated Maturity. 

(10)    Amendment; Supplement; Waiver. Subject to certain exceptions, the provisions of the Indenture relating to
the Notes may be amended or supplemented without notice to any Holder but with the written consent of the Holders of at least a majority in principal amount of the Notes then outstanding, and any existing Default relating to the Notes may be waived
with the written consent of the Holders of a majority in aggregate principal amount of the Notes then outstanding. Without notice to or consent of any Holder, the Issuer, the Guarantor and the Trustee may amend the Indenture as it applies to any
Notes or any of the other terms of such Notes to, among other things, cure any ambiguity or correct or supplement any provision contained in the Indenture or in any Notes which may be defective or inconsistent with any other provision contained
therein. 
 (11)    Defaults and Remedies. If an Event of Default with respect to the Notes occurs and is
continuing (other than an Event of Default relating to certain events of bankruptcy and similar matters with respect to the Issuer, any Significant Subsidiary or any group of the Issuer’s Restricted Subsidiaries that, taken together, would
constitute a Significant Subsidiary), the Trustee or the Holders of at least 25% in principal amount of Notes then outstanding, by written notice to the Issuer (and to the Trustee, if such notice is given by the Holders), may declare the principal
amount of, and accrued and unpaid interest on, all the Notes to be due and payable. Upon such a declaration, such amounts shall be due and payable immediately. If an Event of Default relating to certain events of bankruptcy and similar matters with
respect to the Issuer, any Significant Subsidiary or any group of the Issuer’s Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary occurs, the principal amount of, and accrued and unpaid interest on, all the
Notes shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to the terms of the Indenture, the Trustee is not obligated to exercise any of its rights or powers under the Indenture unless the Holders have offered security or indemnity satisfactory to the Trustee. The Indenture permits, subject to
certain limitations therein provided, Holders of a majority in principal amount of the Notes then outstanding to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or
power conferred on the Trustee with respect to the Notes. The Trustee may withhold from Holders of Notes notice of any continuing Default with respect to the Notes (except a Default in payment of principal, or premium if any, or accrued and unpaid
interest with respect to the Notes) in accordance with the provisions of the Indenture if a committee of the Trustee’s Trust Officers in good faith determines that withholding notice is in the interest of the Holders. 

  
 3 

 (12)    Trustee Dealings With Issuer. Subject to certain limitations
provided in the Indenture, the Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or its Affiliates with the same rights it would have if it were not Trustee. 

(13)    No Recourse Against Others. A director, officer, employee or shareholder, as such, of the Issuer or of the
Guarantor shall not have any liability for any obligations of the Issuer or the Guarantor under the Notes, the Note Guarantee or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting
a Note, each Holder waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Notes and the Note Guarantee. 

(14)    Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or
an authenticating agent. 
 (15)    Governing Law. The laws of the State of New York shall govern this Note and
the Indenture, without regard to principles of conflicts of law to the extent that the application of the laws of another jurisdiction would be required thereby. 

(16)    Abbreviations and Defined Terms. Customary abbreviations may be used in the name of a Holder of a Note or
an assignee, such as: TEN CON (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

(17)    CUSIP Numbers. The Issuer has caused CUSIP numbers to be printed on the Notes as a convenience to the
Holders of the Notes. No representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice to Holders. Reliance may be placed only on the other elements of identification printed on the Notes,
and any such notice shall not be affected by any defect or omission of such CUSIP numbers.
