UAL, at its option, may redeem some or all of the Notes at any time at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes being redeemed and (2) a make-whole amount based on the sum of the present values of the remaining scheduled payments of principal and interest on the Notes discounted to the redemption date using a rate based on comparable U.S. Treasury securities plus 50 basis points, plus, in either case, accrued and unpaid interest to the redemption date.

The Fifth Supplemental Indenture is filed herewith as Exhibit 4.2, and is incorporated by reference herein.

Barclays, individually and not as a representative, may (but shall not be obligated to) make payment of the Purchase Price for the Securities to be purchased by any Underwriter whose check or checks shall not have been received by the Closing Date.

3.    Conditions of Underwriters’ Obligations. The several obligations of the Underwriters to purchase and pay for the Securities pursuant to this Agreement are subject to the following conditions:

(a)    On the Closing Date, no stop order suspending the effectiveness of the Registration Statement shall have been issued under the Securities Act and no proceedings therefor shall have been instituted or threatened by the Commission.

(b)    On the Closing Date, the Underwriters shall have received an opinion and negative assurance letter of Hughes Hubbard & Reed LLP, counsel for the Company and the Guarantor, dated the Closing Date, in form and substance reasonably satisfactory to the Representative.

(c)    On the Closing Date, the Underwriters shall have received an opinion of the Senior Managing Counsel — Finance, Fleet & Loyalty of the Guarantor, dated the Closing Date, in form and substance reasonably satisfactory to the Representative.

(e)    Subsequent to the execution and delivery of this Agreement, there shall not have occurred any change, or any development or event involving a prospective change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries considered as one enterprise that, in the judgment of the Representative, is material and adverse and that makes it, in the judgment of the Representative, impracticable to proceed with the completion of the public offering of the Securities on the terms and in the manner contemplated by the Time of Sale Prospectus.

(f)    The Underwriters shall have received on the Closing Date a certificate, dated the Closing Date and signed by the President or any Vice President of the Company and of the Guarantor, to the effect that the representations and warranties of the Company and the Guarantor contained in this Agreement are true and correct as of the Closing Date as if made on the Closing Date (except to the extent that they relate solely to an earlier date, in which case they shall be true and accurate as of such earlier date), that the Company and the Guarantor have performed all of their respective obligations to be performed hereunder on or prior to the Closing

11

Date and that, subsequent to the execution and delivery of this Agreement, there shall not have occurred any material adverse change, or any development or event involving a prospective material adverse change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries considered as one enterprise, except as set forth in or contemplated by the Time of Sale Prospectus.

(g)    The Underwriters shall have received from Ernst & Young LLP (i) a letter, dated no earlier than the date hereof, in form and substance satisfactory to the Representative, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information included or incorporated by reference in the Registration Statement, the preliminary prospectus and the Prospectus, and (ii) a letter, dated the Closing Date, which meets the above requirements, except that the specified date therein referring to certain procedures performed by Ernst & Young LLP will not be a date more than three business days prior to the Closing Date for purposes of this subsection.

(h)    Subsequent to the execution and delivery of this Agreement and prior to the Closing Date, there shall not have been any downgrading in the rating accorded any securities issued or guaranteed by the Company or the Guarantor (except for any pass through certificates) by any “nationally recognized statistical rating organization”, as such term is defined in Section 3(a)(62) of the Exchange Act, or any public announcement that any such organization has under surveillance or review, in each case for possible change, its ratings of any such securities other than pass through certificates (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating).

(i)    At the Closing Date, the Indenture shall have been duly executed and delivered by each of the parties thereto.

(j)    On the Closing Date, the representations and warranties of the Company and the Guarantor contained herein shall be true and correct as if made on the Closing Date (except to the extent that they relate solely to an earlier date, in which case they shall be true and correct as of such earlier date); and the statements of the Company, the Guarantor and their respective officers made in any certificates delivered pursuant to this Agreement on the Closing Date shall be true and correct on and as of the Closing Date.

The Company will furnish the Underwriters with such conformed copies of such opinions, certificates, letters and documents as the Underwriters may reasonably request.

4.    Certain Covenants of the Company and the Guarantor. Each of the Company and the Guarantor jointly and severally covenants with each Underwriter as follows:

(a)    During the period described in the following sentence of this Section 4(a), the Company shall advise the Representative promptly of any proposal to amend or supplement the Registration Statement, the Time of Sale Prospectus or the Prospectus (except by documents filed under the Exchange Act) and will not effect such amendment or supplement (except by documents filed under the Exchange Act) without the consent of the Representative, which

12

consent will not be unreasonably withheld. If, at any time after the public offering of the Securities, the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales of the Securities by an Underwriter or a dealer, any event shall occur as a result of which it is necessary to amend or supplement the Prospectus so that the statements therein will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, contain a material misstatement or omission, or if it is necessary to amend the Registration Statement or amend or supplement the Prospectus to comply with law, the Company shall prepare and furnish at its expense to the Underwriters and to the dealers (whose names and addresses the Representative will furnish to the Company) to which Securities may have been sold by the Representative on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, contain a material misstatement or omission, or amendments or supplements to the Registration Statement or the Prospectus so that the Registration Statement or the Prospectus, as so amended or supplemented, will comply with law and cause such amendments or supplements to be filed promptly with the Commission.

(b)    During the period mentioned in paragraph (a) above, the Company shall notify each Underwriter immediately of (i) the effectiveness of any amendment to the Registration Statement, (ii) the transmittal to the Commission for filing of any supplement to the Prospectus or any document that would as a result thereof be incorporated by reference in the Prospectus, (iii) the receipt of any comments from the Commission with respect to the Registration Statement or the Prospectus, (iv) any request by the Commission to the Company for any amendment to the Registration Statement or any supplement to the Prospectus or for additional information relating thereto or to any document incorporated by reference in the Prospectus and (v) receipt by the Company of any notice of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, the suspension of the qualification of the Securities for offering or sale in any jurisdiction, or the institution or threatening of any proceeding for any of such purposes; and the Company agrees to use every reasonable effort to prevent the issuance of any such stop order and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment and the Company shall endeavor (subject to the proviso to Section 4(g)), in cooperation with the Underwriters, to prevent the issuance of any such stop order suspending such qualification and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment.

(c)    During the period mentioned in paragraph (a) above, the Company will furnish to each Underwriter as many conformed copies of the Registration Statement (as originally filed), the Time of Sale Prospectus, the Prospectus, and all amendments and supplements to such documents (excluding all exhibits and documents filed therewith or incorporated by reference therein) and as many conformed copies of all consents and certificates of experts, in each case as soon as available and in such quantities as each Underwriter reasonably requests.

13

(d)    Promptly following the execution of this Agreement, the Company will prepare a Prospectus that complies with the Securities Act and that sets forth the principal amount of the Securities and their terms not otherwise specified in the preliminary prospectus or the Basic Prospectus included in the Registration Statement, the name of each Underwriter and the principal amount of the Securities that each severally has agreed to purchase, the name of each Underwriter, if any, acting as representative of the Underwriters in connection with the offering, the price at which the Securities are to be purchased by the Underwriters from the Company, any initial public offering price, any selling concession and reallowance and any delayed delivery arrangements, and such other information as the Representative and the Company deem appropriate in connection with the offering of the Securities. The Company will timely transmit copies of the Prospectus to the Commission for filing pursuant to Rule 424 under the Securities Act.

(e)    The Company shall furnish to each Underwriter a copy of each free writing prospectus relating to the offering of the Securities prepared by or on behalf of, used by, or referred to by the Company and shall not use or refer to any proposed free writing prospectus to which the Representative reasonably objects.

(f)    If the Time of Sale Prospectus or any “issuer free writing prospectus” is being used to solicit offers to buy the Securities at a time when a Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” in order to make the statements therein, in the light of the circumstances when it is delivered to a prospective purchaser, not misleading in any material respect, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus or any “issuer free writing prospectus” conflicts with the information contained in the Registration Statement then on file, or if it is necessary to amend or supplement the Time of Sale Prospectus or any “issuer free writing prospectus” to comply with applicable law, the Company shall forthwith prepare, file promptly with the Commission and furnish, at the Company’s expense, to the Underwriters and to the dealers (whose names and addresses the Representative will furnish to the Company) to which Securities may have been sold by the Representative on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Time of Sale Prospectus or such “issuer free writing prospectus” so that the statements in the Time of Sale Prospectus or such “issuer free writing prospectus”, as so amended or supplemented, will not, in the light of the circumstances when it is delivered to a prospective purchaser, be misleading in any material respect or so that the Time of Sale Prospectus or such “issuer free writing prospectus”, as so amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus or such “issuer free writing prospectus”, as amended or supplemented, will comply with applicable law.

(g)    The Company shall, in cooperation with the Underwriters, endeavor to arrange for the qualification of the Securities for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representative reasonably designates and will endeavor to maintain such qualifications in effect so long as required for the distribution of such Securities; provided that neither the Company nor the Guarantor shall be required to (i) qualify as a foreign corporation or as a dealer in securities, (ii) file a general consent to service of process or (iii) subject itself to taxation in any such jurisdiction.

14

(h)    During the period of ten years after the Closing Date, the Company will promptly furnish to each Underwriter, upon request, copies of all Annual Reports on Form 10-K and any definitive proxy statement of the Company (including any successor by merger of the Company) filed with the Commission; provided that (a) filing such documents with the Commission or (b) providing a website address at which such Annual Reports and any such definitive proxy statements may be accessed will satisfy this clause (h).

(i)    If the third anniversary of the initial effective date of the Registration Statement occurs before all the Securities have been sold by the Underwriters, then prior to the third anniversary the Company and the Guarantor shall file a new shelf registration statement and take any other action necessary to permit the public offering of the Securities to continue without interruption, in which case references herein to the Registration Statement shall include the new registration statement as it shall become effective.

(j)    Between the date of this Agreement and the date that is 30 days after the Closing Date, the Company and the Guarantor shall not, without the prior written consent of the Representative, offer, sell or enter into any agreement to sell (as public debt securities registered under the Securities Act or as debt securities which may be resold in a transaction exempt from the registration requirements of the Securities Act in reliance on Rule 144A thereunder and which are marketed through the use of a disclosure document containing substantially the same information as a prospectus for similar debt securities registered under the Securities Act) any debt securities issued or guaranteed by the Company or the Guarantor and having the term of more than one year (other than (i) the Securities, (ii) any equipment notes, pass through certificates, equipment trust certificates or equipment purchase certificates secured by aircraft owned by the Company (or rights relating thereto), (iii) any notes convertible into shares of common stock of the Company, and (iv) any municipal bonds relating to financing or refinancing any airport facilities).

(k)    The Company shall prepare a final term sheet relating to the offering of the Securities, containing only information that describes the final terms of the Securities or the offering in a form consented to by the Representative and shall file such final term sheet within the period required by Rule 433(d)(5)(ii) under the Securities Act following the date the final terms have been established for the offering of the Securities.

(l)    Neither the Company nor the Guarantor will take, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities.

5.    Certain Covenants of the Underwriters. Each Underwriter represents, warrants and covenants that it has not made and will not make any offer relating to the Securities that would constitute an issuer free writing prospectus; provided that this Section 5 shall not prevent any Underwriter from transmitting or otherwise making use of one or more customary “Bloomberg Screens” to offer the Securities or convey final pricing terms thereof that contain only information contained in the Time of Sale Prospectus.

15

6.    Indemnification and Contribution. (a) Each of the Company and the Guarantor agrees jointly and severally to indemnify and hold harmless each Underwriter, its directors and officers and the affiliates of each Underwriter who have, or who are alleged to have, participated in the distribution of the Securities as underwriters, and each Person, if any, who controls such Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any “issuer free writing prospectus” as defined in Rule 433(h) under the Securities Act, any “issuer information” that the Company or the Guarantor has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act or the Prospectus, or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any of the aforementioned losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information furnished to the Company in writing by any Underwriter through the Representative expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus or the Prospectus, or any amendment or supplement thereto (the “Underwriter Information”).

(b)    Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the Guarantor, their respective directors, each of their respective officers who signed the Registration Statement and each person, if any, who controls the Company or the Guarantor within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and the Guarantor to such Underwriter but only with reference to the Underwriter Information provided by such Underwriter.

(c)    In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either paragraph (a) or (b) above, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such paragraph. The indemnifying party, upon request of the indemnified party, shall, and the indemnifying party may elect to, retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and the indemnifying party shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include

16

both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, or (iii) the indemnifying party shall have failed to retain counsel as required by the prior sentence to represent the indemnified party within a reasonable amount of time. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representative in the case of parties indemnified pursuant to paragraph (a) above and by the Company in the case of parties indemnified pursuant to paragraph (b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested in writing an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph (c), the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement, unless such fees and expenses are being disputed in good faith. The indemnifying party at any time may, subject to the last sentence of this paragraph (c), settle or compromise any proceeding described in this paragraph (c), at the expense of the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d)    To the extent the indemnification provided for in paragraph (a) or (b) of this Section 6 is required to be made but is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the applicable indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, in connection with the offering of such Securities shall be deemed to be in the

17

same respective proportions as the proceeds from the offering of such Securities received by the Company (before deducting expenses), less total underwriting discounts and commissions received by the Underwriters, and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of such Securities. The relative fault of the Company and the Guarantor, on the one hand, and of the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Guarantor or information supplied by any Underwriter, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 6 are several in proportion to the respective principal amount of Securities they have purchased hereunder, and not joint.

(e)    The Company, the Guarantor and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 6 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the Securities underwritten by it and distributed to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)     The indemnity and contribution provisions contained in this Section 6 and the representations and warranties of the Company and the Guarantor contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, the Guarantor, each of their respective officers or directors or any person controlling the Company or the Guarantor, and (iii) acceptance of and payment for any of the Securities. The remedies provided for in this Section 6 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

7.    Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities hereunder and the aggregate principal amount of the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Securities, the Representative may make arrangements satisfactory to the Company for the purchase of such Securities by other persons,

18

including any of the non-defaulting Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Securities with respect to which such default or defaults occurs exceeds 10% of the total principal amount of the Securities and arrangements satisfactory to the Representative and the Company for purchase of such Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Guarantor, except as provided in Section 6. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

8.    Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Guarantor or their respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any termination of this Agreement, any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Guarantor or any of their respective representatives, officers or directors or any controlling person and will survive delivery of and payment for the Securities. If for any reason the purchase of the Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 10 hereof and the respective obligations of the Company, the Guarantor and the Underwriters pursuant to Section 6 hereof shall remain in effect. If the purchase of the Securities by the Underwriters is not consummated for any reason other than solely because of the occurrence of the termination of the Agreement pursuant to Section 7 or 9 hereof, the Company and the Guarantor will jointly and severally reimburse the Underwriters for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by the Underwriters in connection with the offering of such Securities and comply with its obligations under Sections 6 and 10 hereof.

9.    Termination. This Agreement shall be subject to termination by notice given by the Representative to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been materially suspended or materially limited on or by, as the case may be, either of the New York Stock Exchange or the NASDAQ Global Market, (ii) trading of any securities of the Company or the Guarantor shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, (iv) there shall have occurred any attack on, or outbreak or escalation of hostilities or act of terrorism involving, the United States, or any change in financial markets or any calamity or crisis that, in each case, in the judgment of the Representative, is material and adverse or (v) there shall have occurred any major disruption of settlements of securities or clearance services in the United States that would materially impair settlement and clearance with respect to the Securities and (b) in the case of any of the events specified in clauses (a)(i) through (v), such event singly or together with any other such event makes it, in the judgment of the Representative, impracticable to market the Securities on the terms and in the manner contemplated in the Time of Sale Prospectus.

19

10.    Payment of Expenses. As among the Company, the Guarantor and the Underwriters, the Company or the Guarantor shall pay all expenses incidental to the performance of the Company’s and the Guarantor’s obligations under this Agreement, including the following:

(i)    expenses incurred in connection with (A) qualifying the Securities for offer and sale under the applicable securities or “blue sky” laws of such jurisdictions in the United States as the Representative reasonably designates (including filing fees and fees and disbursements of counsel for the Underwriters in connection therewith), (B) endeavoring to maintain such qualifications in effect so long as required for the distribution of such Securities, (C) the review (if any) of the offering of the Securities by FINRA, (D) the determination of the eligibility of the Securities for investment under the laws of such jurisdictions as the Underwriters may designate and (E) the preparation and distribution of any blue sky or legal investment memorandum by Milbank LLP, Underwriters’ counsel;

(iii)    the expenses incurred in connection with the preparation, printing and filing of the Registration Statement (including financial statements and exhibits), as originally filed and as amended, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any issuer free writing prospectus and any amendments and supplements to any of the foregoing, including the filing fees payable to the Commission relating to the Securities (within the time period required by Rule 456(b)(1), if applicable), and the cost of furnishing copies thereof to the Underwriters and dealers;

(iv)    expenses incurred in connection with the preparation, printing and distribution of this Agreement, the Securities and the Supplemental Indenture;

(v)    expenses incurred in connection with the delivery of the Securities to the Underwriters;

20

(vi)    reasonable fees and disbursements of the counsel and accountants for the Company and the Guarantor;

(vii)    to the extent the Company is so required under the Indenture, the fees and expenses of the Trustee and any paying agent and the disbursements of their respective counsel;

(viii)    fees charged by rating agencies for rating the Securities (including annual surveillance fees related to the Securities as long as they are outstanding);

(ix)    all other reasonable out-of-pocket expenses incurred by the Underwriters in connection with the transactions contemplated by this Agreement (excluding the fees and disbursements of Milbank LLP as counsel for the Underwriters); and

(x)    except as otherwise provided in the foregoing clauses (i) through (ix), all other expenses incidental to the performance of the Company’s and the Guarantor’s obligations under this Agreement, other than pursuant to Section 6.

11.    Notices. All communications hereunder shall be in writing and effective only upon receipt and, if sent to the Underwriters, shall be mailed, delivered or sent by facsimile transmission and confirmed to the Underwriters c/o Barclays, 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration, Facsimile: (646) 834-8133, and, if sent to the Company, shall be mailed, delivered or sent by facsimile transmission and confirmed to it at 233 South Wacker Drive, Chicago, Illinois 60606, Attention: Treasurer and General Counsel, facsimile number (872) 825-0316; provided, however, that any notice to an Underwriter pursuant to Section 6 shall be sent by facsimile transmission or delivered and confirmed to such Underwriter.

15.    Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

FIFTH SUPPLEMENTAL INDENTURE, dated as of May 9, 2019 (the “Fifth 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 Fifth 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 Fifth Supplemental Indenture.

NOW, THEREFORE, this Fifth Supplemental Indenture witnesseth:

Section 1. Defined Terms. For purposes of this Fifth 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 Fifth Supplemental Indenture.

Section 2. Relation to Original Indenture. The Original Indenture is supplemented and modified as set forth in this Fifth Supplemental Indenture for purposes of the Notes. This Fifth 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 4.875% Senior Notes due 2025. 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 $350,000,000, 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 January 15, 2025.

3.5 Interest. The outstanding principal amount of the Notes shall bear interest at the rate of 4.875% per annum, payable in arrears on January 15 and July 15 of each year (each, an “Interest Payment Date”), commencing on January 15, 2020, to the Persons in whose names the Notes are registered at the close of business on the January 1 and July 1, 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 provided,

1

or, if no interest has been paid or provided for, from May 9, 2019. 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 Barclays Capital Inc. and Citigroup Global Markets Inc., 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, 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 CORPORATION (“DTC”), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF

3

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.

3.14 Amendments.

“, 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);

7

(2)    purchase, redeem or otherwise acquire or retire for value any Equity Interests of the Issuer;

(3)    make any payment on or with respect to, or purchase, 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)    [reserved]; 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

(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

(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 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;

9

(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;

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.

(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;

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.

18

Section 5. Changes in Events of Default Applicable to the Notes.

(a)    Clauses (3), (4) and (5) of Section 6.01 of the Original Indenture shall be amended and restated to read as follows:

(C)    consents to the appointment of a Custodian of it or for all or substantially all of its property; or

(D)    makes a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating to insolvency;

(5)    a court of competent jurisdiction enters an order or decree under any Bankruptcy Law, which remains unstayed and in effect for 90 days, that:

(A)    is for relief against the Issuer, any Significant Subsidiary or any group of the Issuer’s Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary in an involuntary case;

(B)    appoints a Custodian of the Issuer, any of the Issuer’s Restricted Subsidiaries that is a Significant Subsidiary or any group of the Issuer’s Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or all or substantially all of the property of the Issuer, any Significant Subsidiary or any group of the Issuer’s Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary; or

(C)    orders the winding up or liquidation of the Issuer, any Significant Subsidiary or any group of the Issuer’s Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary or any similar relief is granted under any foreign laws.”

19

(b)    The following shall be added to Section 6.01 of the Original Indenture following clause (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.”

Section 7. Additional Definitions. The following definitions shall be applicable for purposes of this Fifth Supplemental Indenture (and, if any term defined below is also defined in the Original Indenture, the definition below shall supersede the definition of such term in the Original Indenture):
