(a) The Notes shall be issuable in registered form without coupons in minimum denominations of $1,000 principal amount and multiples of $1,000 in excess thereof.

(c) Any Defaulted Amounts shall forthwith cease to be payable to the Holder on the relevant payment date but shall accrue interest, to the extent permitted by applicable law, per annum at the rate borne by the Notes, from, and including, such relevant payment date, and such Defaulted Amounts together with any such interest thereon shall be paid by the Company, at its election in each case, as provided in clause (i) or (ii) below:

(i) The Company may elect to make payment of any Defaulted Amounts to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on a special record date for the payment of such Defaulted Amounts, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of the Defaulted Amounts proposed to be paid on each Note and the date of the proposed payment (which shall be not less than 25 days after the receipt by the Trustee of such notice, unless the Trustee shall consent to an earlier date), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount to be paid in respect of such Defaulted Amounts or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Amounts as in this clause provided. Thereupon the Company shall fix a special record date for the payment of such Defaulted Amounts which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment, and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment.

Notice of the proposed payment of such Defaulted Amounts and the special record date therefor having been so delivered, such Defaulted Amounts shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such special record date and shall no longer be payable pursuant to the following clause (ii) of this Section 2.03(c).

(ii) The Company may make payment of any Defaulted Amounts in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, and upon such notice as may be required by such exchange or automated quotation system, if, after written notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Section 2.04Execution, Authentication and Delivery of Notes. The Notes shall be signed in the name and on behalf of the Company by the manual or facsimile signature of an Officer of the Company.

At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes, without any further action by the Company hereunder, other than delivery of an Officer’s Certificate pursuant to Section 17.05. For the avoidance of doubt, the Trustee shall not be obligated to authenticate a

Note hereunder unless and until it has received a Company Order in accordance with the terms hereof.

Only such Notes as shall bear thereon a certificate of authentication substantially in the form set forth on the form of Note attached as Exhibit A hereto, executed manually by an authorized signatory of the Trustee (or an authenticating agent appointed by the Trustee as provided by Section 17.10), shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon any Note executed by the Company shall be conclusive evidence that the Note so authenticated has been duly authenticated and delivered hereunder and that the Holder is entitled to the benefits of this Indenture.

In case any Officer of the Company who shall have signed any of the Notes shall cease to be such Officer before the Notes so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Company, such Notes nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Notes had not ceased to be such Officer of the Company; and any Note may be signed on behalf of the Company by such persons as, at the actual date of the execution of such Note, shall be the Officers of the Company, although at the date of the execution of this Indenture any such Person was not such an Officer.

Section 2.05Exchange and Registration of Transfer of Notes; Restrictions on Transfer; Depositary. (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register maintained in such office or in any other office or agency of the Company designated pursuant to Section 4.02, the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Notes and of transfers of Notes.

The Trustee is hereby initially appointed the “Note Registrar” for the purpose of registering Notes and transfers of Notes as herein provided. The Company may appoint one or moreco-Note Registrars in accordance with Section 4.02.

Upon surrender for registration of transfer of any Note to the Note Registrar or anyco-Note Registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.05, the Company shall execute, and upon receipt of a Company Order, the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as may be required by this Indenture.

Whenever any Notes are so surrendered for exchange, the Company shall execute, and upon receipt of a Company Order, the Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive, bearing registration numbers not contemporaneously outstanding.

All Notes presented or surrendered for registration of transfer or for exchange, repurchase or exchanges for cash, Ordinary Shares or a combination thereof shall (if so required by the Company, the Trustee, the Note Registrar or anyco-Note Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Note Registrar and the Company and duly executed, by the Holder thereof or itsattorney-in-fact duly authorized in writing.

No service charge shall be imposed by the Company, the Trustee, the Note Registrar, anyco-Note Registrar or the Paying Agent for any exchange or registration of transfer of Notes, but the Trustee, the Note Registrar or the Company may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of new Notes issued upon such exchange or registration of transfer being different from the name of the Holder of the old Notes surrendered for exchange or registration of transfer.

None of the Company, the Trustee, the Note Registrar or anyco-Note Registrar shall be required to exchange or register a transfer of (i) any Notes surrendered for exchanges for cash, Ordinary Shares or a combination thereof or, if a portion of any Note is surrendered for exchanges for cash, Ordinary Shares or a combination thereof, such portion thereof surrendered for exchanges for cash, Ordinary Shares or a combination thereof, (ii) any Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with Article 15 or (iii) any Notes selected for redemption in accordance with Article 16, except the unredeemed portion of any Note being redeemed in part.

All Notes issued upon any registration of transfer or exchange of Notes in accordance with this Indenture shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture as the Notes surrendered upon such registration of transfer or exchange.

The transfer and exchange of beneficial interests in a Global Note that does not involve the issuance of a Physical Note shall be effected through the Depositary (but not the Trustee or the Custodian) in accordance with this Indenture (including the restrictions on transfer set forth herein) and the procedures of the Depositary therefor.

(c) Every Note that bears or is required under this Section 2.05(c) to bear the legend set forth in this Section 2.05(c) (together with any Ordinary Shares issued upon exchange of the Notes that are required to bear the legend set forth in Section 2.05(d), collectively, the “Restricted Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.05(c) (including those contained in the legend set forth below), unless such restrictions on

transfer shall be eliminated or otherwise waived by written consent of the Company, and the Holder of each such Restricted Security, by such Holder’s acceptance thereof, agrees to be bound by all such restrictions on transfer. As used in this Section 2.05(c) and Section 2.05(d), the term “transfer” encompasses any sale, pledge, transfer or other disposition whatsoever of any Restricted Security. For the avoidance of doubt, nothing in this Section 2.05(c) shall be deemed to prevent the transfer of any Note by any Holder to any Affiliate of such Holder in a transaction that is otherwise in compliance with the Securities Act.

Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date that is one year after the last date of original issuance of the Notes, or such shorter period of time as permitted by Rule 144 or any successor provision thereto, and (2) such later date, if any, as may be required by applicable law, including as a result of the affiliate status of any holder of a Note, any certificate evidencing such Note (and all securities issued in exchange therefor or substitution thereof, other than Ordinary Shares, if any, issued upon exchange thereof, which shall bear the legend set forth in Section 2.05(d), if applicable) shall bear a legend in substantially the following form (unless such Notes have been transferred pursuant to a registration statement that has become or been declared effective under the Securities Act and that was effective at the time of such transfer, or sold pursuant to the exemption from registration provided by Rule 144 or any similar provision then in force under the Securities Act, or unless otherwise agreed by the Company in writing, with notice thereof to the Trustee):

restricted CUSIP number. The Company shall promptly notify the Trustee in writing upon the occurrence of the Resale Restriction Termination Date and promptly after a registration statement, if any, with respect to the Notes or any Ordinary Shares delivered upon exchange of the Notes has been declared effective under the Securities Act.

Notwithstanding any other provisions of this Indenture (other than the provisions set forth in this Section 2.05(c)), a Global Note may not be transferred as a whole or in part except (i) by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global Note in certificated form made upon request of a member of, or a participant in, the Depositary (for itself or on behalf of a beneficial holder) by written notice given to the Trustee by or on behalf of the Depositary in accordance with customary procedures of the Depositary and in compliance with this Section 2.05(c).

Physical Notes issued in exchange for all or a part of the Global Note pursuant to this Section 2.05(c) shall be registered in such names and in such authorized denominations as the Depositary, pursuant to instructions from its direct or indirect participants or otherwise, or, in the case of clause (iii) or (iv) of the immediately preceding paragraph, the relevant Beneficial Holder, shall instruct the Trustee in writing. Upon execution and authentication, the Trustee

shall deliver at the Company’s expense such Physical Notes to the Persons in whose names such Physical Notes are so registered.

At such time as all interests in a Global Note have been exchanged for cash, Ordinary Shares or a combination thereof, canceled, repurchased, redeemed or transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance with standing procedures and existing instructions between the Depositary and the Custodian.

(2) AGREES FOR THE BENEFIT OF THE COMPANY AND THE GUARANTORS THAT IT WILL NOT OFFER, SELL, PLEDGE OR OTHERWISE TRANSFER THIS SECURITY OR ANY BENEFICIAL INTEREST HEREIN PRIOR TO THE DATE THAT IS THE LATER OF (X) ONE YEAR AFTER THE LAST ORIGINAL ISSUE DATE OF THE SERIES OF NOTES UPON THE EXCHANGE OF WHICH THIS SECURITY WAS ISSUED OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY RULE 144 UNDER THE SECURITIES ACT OR ANY SUCCESSOR PROVISION THERETO AND (Y) SUCH LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE LAW, EXCEPT:

(A) TO ITERUM OR ANY SUBSIDIARY THEREOF (INCLUDING THE COMPANY), OR

(B) PURSUANT TO A REGISTRATION STATEMENT WHICH HAS BECOME EFFECTIVE UNDER THE SECURITIES ACT, OR

(D) PURSUANT TO AN EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT OR ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

PRIOR TO THE REGISTRATION OF ANY TRANSFER IN ACCORDANCE WITH CLAUSE (2)(D) ABOVE, THE COMPANY, THE GUARANTORS AND THE TRANSFER AGENT FOR THE COMPANY’S ORDINARY SHARES RESERVE THE RIGHT TO REQUIRE THE DELIVERY OF SUCH LEGAL OPINIONS, CERTIFICATIONS OR OTHER EVIDENCE AS MAY REASONABLY BE REQUIRED IN ORDER TO DETERMINE THAT THE PROPOSED TRANSFER IS BEING MADE IN COMPLIANCE WITH THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. NO REPRESENTATION IS MADE AS TO THE AVAILABILITY OF ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT.

Any such Ordinary Shares as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such Ordinary Shares for exchange in accordance with the procedures of the transfer agent for the Ordinary Shares, be exchanged for a new certificate or certificates for a like aggregate number of Ordinary Shares, which shall not bear the restrictive legend required by this Section 2.05(d).

(e) Notwithstanding anything contained herein to the contrary, neither the Trustee nor the Note Registrar shall be responsible for ascertaining whether any transfer complies with the registration provisions of, or exemptions from, the Securities Act, applicable state securities laws or other applicable law.

(f) Any Note or Ordinary Shares issued upon the exchange of a Note that is repurchased or owned by any Affiliate of the Company or Iterum (or any Person who was an Affiliate of the Company or Iterum at any time during the three months immediately preceding) may not be resold by such Affiliate (or such Person, as the case may be) unless registered under the Securities Act or resold pursuant to an exemption from the registration requirements of the Securities Act in a transaction that results in such Note or Ordinary Shares, as the case may be, no longer being a “restricted security” (as defined under Rule 144). Except as provided for in Section 2.10, each of the Company and Iterum shall cause any Note that is repurchased or owned by it to be surrendered to the Trustee for cancellation in accordance with Section 2.08.

(g) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among depositary participants or Beneficial Holders of interests in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(h) Neither the Trustee nor any agent shall have any responsibility or liability for any actions or omissions taken or not taken by the Depositary. All notices and communications to be given to the Holders and all payments to be made to the Holders in respect of the Notes shall be given or made only to, or upon the order of, the registered Holder(s) (which shall be the Depositary or its nominee in the case of a Global Note). The rights of Beneficial Holders in any Global Note shall be exercised only through the Depositary subject to the applicable procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any Beneficial Holders.

Section 2.06Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon receipt of a Company Order the Trustee or an authenticating agent appointed by the Trustee shall authenticate and deliver, a new Note, bearing a registration number not contemporaneously outstanding, in exchange and substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed, lost or stolen. In every case the applicant for a substituted Note shall

furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security and/or indemnity satisfactory to the Company, the Trustee, or if applicable, the authenticating agent as may be required by them to save each of them harmless from any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company, to the Trustee and, if applicable, to such authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.

The Trustee or such authenticating agent may authenticate any such substituted Note and deliver the same upon the receipt of such security and/or indemnity as the Trustee, the Company and, if applicable, such authenticating agent may require. No service charge shall be imposed by the Company, the Trustee, the Note Registrar, anyco-Note Registrar or the Paying Agent upon the issuance of any substitute Note, but the Company and/or the Trustee may require a Holder to pay a sum sufficient to cover any documentary, stamp or similar issue or transfer tax required in connection therewith as a result of the name of the Holder of the new substitute Note being different from the name of the Holder of the old Note that became mutilated or was destroyed, lost or stolen. In case any Note that has matured or is about to mature or has been surrendered for required repurchase or redemption or is about to be exchanged in accordance with Article 14 shall become mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of issuing a substitute Note, pay or authorize the payment of or exchange or authorize the exchange of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or exchange shall furnish to the Company, to the Trustee and, if applicable, to such authenticating agent such security and/or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or connected with such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the Company, the Trustee and, if applicable, any Paying Agent or Exchange Agent of the destruction, loss or theft of such Note and of the ownership thereof.

Every substitute Note issued pursuant to the provisions of this Section 2.06 by virtue of the fact that any Note is destroyed, lost or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set forth in) this Indenture equally and proportionately with any and all other Notes duly issued hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement, payment, redemption, exchange or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement, payment, redemption, exchange or repurchase of negotiable instruments or other securities without their surrender.

Section 2.07Temporary Notes. Pending the preparation of Physical Notes, the Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Physical Notes but with such omissions, insertions and variations

as may be appropriate for temporary Notes, all as may be determined by the Company. Every such temporary Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Physical Notes. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such authenticating agent Physical Notes (other than any Global Note) and thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary Notes an equal aggregate principal amount of Physical Notes. Such exchange shall be made by the Company at its own expense and without any charge therefor. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Physical Notes authenticated and delivered hereunder.

Section 2.08Cancellation of Notes Paid, Exchanged, Etc. The Company shall cause all Notes surrendered for the purpose of payment, redemption, repurchase, exchange for cash, Ordinary Shares or a combination thereof, or registration of transfer or exchange, if surrendered to any Person other than the Trustee (including any of the Company’s agents or the Guarantors’ or the Company’s respective Subsidiaries or Affiliates), to be surrendered to the Trustee for cancellation. All Notes delivered to the Trustee shall be canceled promptly by it, and no Notes shall be authenticated in exchange therefor except as expressly permitted by any of the provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its customary procedures and, after such disposition, shall deliver evidence of such disposition to the Company, at the Company’s written request in a Company Order.

Section 2.09CUSIP and ISIN Numbers. The Company in issuing the Notes may use “CUSIP” and/or “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and/or “ISIN” numbers in all notices issued to Holders as a convenience to such Holders;provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or on such notice and that reliance may be placed only on the other identification numbers printed on the Notes. The Company shall promptly notify the Trustee in writing of any change in the “CUSIP” and/or “ISIN” numbers.

Section 2.10Additional Notes; Repurchases. The Company may, without the consent of the Holders, but subject in all cases to the Cap, reopen this Indenture and issue additional Notes hereunder with the same terms as the Notes initially issued hereunder (except for the issue date, issue price and, in some cases, the initial interest accrual date);provided that if any such additional Notes are not fungible with the Notes initially issued hereunder for U.S. federal income tax and securities law purposes, such additional Notes shall have one or more separate CUSIP numbers. Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a Company Order, an Officer’s Certificate and an Opinion of Counsel, such Officer’s Certificate and Opinion of Counsel to cover such matters applicable to the issuance of additional Notes, in addition to those required by Section 17.05. In addition, the Company and/or the Guarantors may, to the extent permitted by law, and directly or indirectly (regardless

of whether such Notes are surrendered to the Company or the Guarantors), repurchase Notes in the open market or otherwise, whether by the Company, the Guarantors or their respective Subsidiaries or through a private or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives. The Company and the Guarantors shall cause any Notes so repurchased (other than Notes repurchased pursuant to cash-settled swaps or other derivatives) to be surrendered to the Trustee for cancellation in accordance with Section 2.08.

The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(b) If the Company shall act as its own Paying Agent, it will, on or before each due date of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, and any accrued and unpaid interest on, the Notes, set aside, segregate and hold in trust for the benefit of the Holders of the Notes a sum sufficient to pay such principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) and any such accrued and unpaid interest so becoming due and will promptly notify the Trustee in writing of any failure to take such action and of any failure by the Company to make any payment of the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, or any accrued and unpaid interest on, the Notes when the same shall become due and payable.

(c) Anything in this Section 4.04 to the contrary notwithstanding, the Company may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay, cause to be paid or deliver to the Trustee all sums or amounts held in trust by the Company or any Paying Agent hereunder as required by this Section 4.04, such sums or amounts to be held by the Trustee upon the trusts herein contained and upon such payment or delivery by the Company or any Paying Agent to the Trustee, the Company or such Paying Agent shall be released from all further liability but only with respect to such sums or amounts.

and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money and Ordinary Shares, and all liability of the Company as trustee thereof, shall thereupon cease.

(e) Upon the occurrence of any Event of Default specified in Section 6.01(i) or Section 6.01(j), the Trustee shall automatically be the Paying Agent.

Section 6.02Acceleration; Rescission and Annulment. If one or more Events of Default shall have occurred and be continuing (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body), then, and in each and every such case (other than an Event of Default

specified in Section 6.01(i) or Section 6.01(j) with respect to the Guarantors, the Company or a Significant Subsidiary), unless the principal of all of the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding determined in accordance with Section 8.04, by notice in writing to the Company (and to the Trustee if given by Holders), may (and the Trustee, at the written request of such Holders, shall) declare 100% of the principal of, and any accrued and unpaid interest on, all the Notes to be due and payable immediately, and upon any such declaration the same shall become and shall automatically be immediately due and payable, anything contained in this Indenture or in the Notes to the contrary notwithstanding. If an Event of Default specified in Section 6.01(i) or Section 6.01(j) with respect to the Guarantors, the Company or a Significant Subsidiary occurs and is continuing, 100% of the principal of, and accrued and unpaid interest, if any, on, all Notes shall become and shall automatically be immediately due and payable.

The immediately preceding paragraph, however, is subject to the conditions that if, at any time after the principal of the Notes shall have been so declared due and payable, and before any judgment or decree for the payment of the monies due shall have been obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the Trustee a sum sufficient to pay installments of any accrued and unpaid interest upon all Notes and the principal of any and all Notes that shall have become due otherwise than by acceleration (with interest on overdue installments of accrued and unpaid interest, and on such principal at the rate borne by the Notes at such time to the extent such interest is permitted by law) and amounts due to the Trustee pursuant to Section 7.06, and if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (2) any and all existing Events of Default under this Indenture, other than the nonpayment of the principal of and accrued and unpaid interest, if any, on Notes that shall have become due solely by such acceleration, shall have been cured or waived pursuant to Section 6.09, then and in every such case (except as provided in the immediately succeeding sentence) the Holders of the Specified Percentage in aggregate principal amount of the Notes then outstanding, by written notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect to the Notes and rescind and annul such declaration and its consequences and such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event of Default, or shall impair any right consequent thereon. Notwithstanding anything to the contrary herein, no such waiver or rescission and annulment shall extend to or shall affect any Default or Event of Default resulting from (i) the nonpayment of the principal of, or accrued and unpaid interest on, any Notes, (ii) a failure to repurchase any Notes when required or (iii) a failure to pay or deliver or cause to be delivered, as the case may be, the consideration due upon exchange of the Notes.

Section 6.03Special Interest. Notwithstanding anything in this Indenture or in the Notes to the contrary, to the extent the Company elects, the sole remedy for an Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 5.04(b) shall, for the first 360 days after the occurrence of such an Event of Default (and, for the avoidance of doubt, giving effect to the60-day period set forth in Section 6.01(e)), consist exclusively of the right to receive Special Interest on the Notes at a rate equal to (i) 0.25% per

annum of the principal amount of the Notes outstanding for each day during the first 180 calendar days after the occurrence of such an Event of Default during which such Event of Default is continuing (or, if earlier, the date on which such Event of Default is cured or waived as provided for in this Indenture) and (ii) 0.50% per annum of the principal amount of the Notes outstanding for each day from, and including, the 181st calendar day to, but excluding, the 360th calendar day after the occurrence of such an Event of Default during which such Event of Default is continuing (or, if earlier, the date on which such Event of Default is cured or waived as provided for in this Indenture). If the Company elects to pay Special Interest, such Special Interest shall be payable as set forth in Section 2.03(b). On the 361st day after such Event of Default (if the Event of Default relating to the Company’s failure to comply with its obligations as set forth in Section 5.04 is not cured or waived prior to such 361st day), the Notes shall be immediately subject to acceleration as provided in Section 6.02. In the event the Company does not elect to pay Special Interest following an Event of Default in accordance with this Section 6.03 or the Company elected to make such payment but does not pay the Special Interest when due, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

In order to elect to pay Special Interest as the sole remedy during the first 360 days after the occurrence of any Event of Default described in the immediately preceding paragraph, the Company must notify in writing all Holders of the Notes, the Trustee and the Paying Agent of such election prior to the beginning of such360-day period. Upon the failure to timely give such notice, the Notes shall be immediately subject to acceleration as provided in Section 6.02.

In no event shall Special Interest accrue under the terms of this Indenture at a rate per year in excess of 0.50%, regardless of the number of events or circumstances giving rise to the requirement to pay such Special Interest.

This Section 6.03 shall not affect the rights of Holders in the event of the occurrence of any other Event of Default.

Section 6.04Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) of Section 6.01 shall have occurred, the Company shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of the Notes, the whole amount then due and payable on the Notes for principal and interest, if any, with interest on any overdue principal and interest, if any, at the rate borne by the Notes at such time (to the extent such interest on overdue principal and interest is permitted by law), and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 7.06. If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company, any Guarantor or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company, the Guarantors or any other obligor upon the Notes, wherever situated.

In the event there shall be pending proceedings for the bankruptcy or for the reorganization of the Company, any Guarantor or any other obligor on the Notes under Title 11 of the United States Code, or any other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or similar official shall have been appointed for or taken possession of the Company, any Guarantor or such other obligor, the property of the Company, such Guarantor or such other obligor, or in the event of any other judicial proceedings relative to the Company, such Guarantor or such other obligor upon the Notes, or to the creditors or property of the Company, such Guarantor or such other obligor, the Trustee, irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.04, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal and accrued and unpaid interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to file such proofs of claim and other papers or documents and to take such other actions as it may deem necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceedings relative to the Company, any Guarantor or any other obligor on the Notes, its or their creditors, or its or their property, and to collect and receive any monies or other property payable or deliverable on any such claims, and to distribute the same after the deduction of any amounts due to the Trustee under Section 7.06; and any receiver, assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is hereby authorized by each of the Holders to make such payments to the Trustee, as administrative expenses, and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it for reasonable compensation, expenses, advances and disbursements, including agents and counsel fees, and including any other amounts due to the Trustee under Section 7.06, incurred by it up to the date of such distribution. To the extent that such payment of reasonable compensation, expenses, advances and disbursements out of the estate in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, monies, securities and other property that the Holders of the Notes may be entitled to receive in such proceedings, whether in liquidation or under any plan of reorganization or arrangement or otherwise.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting such Holder or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

All rights of action and of asserting claims under this Indenture, or under any of the Notes, may be enforced by the Trustee without the possession of any of the Notes, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, after provision for the payment of the reasonable

compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes.

In any proceedings brought by the Trustee (and in any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party) the Trustee shall be held to represent all the Holders of the Notes, and it shall not be necessary to make any Holders of the Notes parties to any such proceedings.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such proceedings shall have been discontinued or abandoned because of any waiver pursuant to Section 6.09 or any rescission and annulment pursuant to Section 6.02 or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Guarantors, the Holders and the Trustee shall, subject to any determination in such proceeding, be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Guarantors, the Holders and the Trustee shall continue as though no such proceeding had been instituted.

Section 6.05Application of Monies Collected by Trustee. Any monies or property collected by the Trustee pursuant to this Article 6 with respect to the Notes shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such monies or property, upon presentation of the several Notes, and stamping thereon the payment, if only partially paid, and upon surrender thereof, if fully paid:

First, to the payment of all amounts due the Trustee, the Exchange Agent and the Paying Agent under this Indenture;

Second, to holders of Senior Debt to the extent required by Article 18;

Third, in case the principal of the outstanding Notes shall not have become due and be unpaid, to the payment of any interest on, and any cash due upon exchange of, the Notes in default in the order of the date due of the payments of such interest and cash due upon exchange, as the case may be, with interest (to the extent that such interest is permitted by applicable law and has been collected by the Trustee) upon such overdue amounts at the rate borne by the Notes at such time, such payments to be made ratably to the Persons entitled thereto;

Fourth, in case the principal of the outstanding Notes shall have become due, by declaration or otherwise, and be unpaid, to the payment of the whole amount (including, if applicable, the payment of the Redemption Price and the Fundamental Change Repurchase Price and any cash due upon exchange) then owing and unpaid upon the Notes for principal and interest, if any, with interest on the overdue principal and (to the extent that such interest is permitted by applicable law and has been collected by the Trustee) upon such overdue installments of interest at the rate borne by the Notes at such time, and in case such monies shall be insufficient to pay in full the whole amounts so due and unpaid upon the Notes, then to the payment of such principal (including, if applicable, the Redemption Price and the Fundamental Change Repurchase Price and the cash due upon exchange) and any interest without preference or priority of principal over any interest, or of any interest over principal, or of any installment of

interest over any other installment of interest, or of any Note over any other Note, ratably to the aggregate of such principal (including, if applicable, the Redemption Price and the Fundamental Change Repurchase Price and any cash due upon exchange) and any accrued and unpaid interest; and

Fifth, to the payment of the remainder, if any, to the Company.

Section 6.06Proceedings by Holders. Except to enforce the right to receive payment of principal (including, if applicable, the Redemption Price and the Fundamental Change Repurchase Price) or interest when due, or the right to receive payment or delivery of the consideration due upon exchange, no Holder of any Note shall have any right by virtue of or by availing of any provision of this Indenture to institute any suit, action or proceeding in equity or at law upon or under or with respect to this Indenture, or for the appointment of a receiver, trustee, liquidator, custodian or other similar official, or for any other remedy hereunder, unless:

(a) such Holder previously shall have given to the Trustee written notice of an Event of Default and of the continuance thereof, as herein provided;

(b) Holders of at least 25% in aggregate principal amount of the Notes then outstanding shall have made written request upon the Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder;

(c) such Holders shall have offered to the Trustee such security and/or indemnity satisfactory to it against any loss, liability or expense to be incurred therein or thereby;

(d) the Trustee has not complied with such request for 60 days after its receipt of such notice, request and offer of security and/or indemnity; and

(e) no direction that, in the opinion of the Trustee, is inconsistent with such written request shall have been given to the Trustee by the Holders of the Specified Percentage of the aggregate principal amount of the Notes then outstanding within such60-day period pursuant to Section 6.09,

it being understood and intended, and being expressly covenanted by the taker and Holder of every Note with every other taker and Holder and the Trustee that no one or more Holders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holder, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all Holders (except as otherwise provided herein), it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are prejudicial to other Holders. For the protection and enforcement of this Section 6.06, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

Notwithstanding any other provision of this Indenture and any provision of any Note, the right of any Holder to receive payment or delivery, as the case may be, of (x) the principal (including the Redemption Price and the Fundamental Change Repurchase Price, if applicable) of, (y) accrued and unpaid interest, if any, on, and (z) the consideration due upon exchange of, such Note, on or after the respective due dates expressed or provided for in such Note or in this Indenture, or to institute suit for the enforcement of any such payment or delivery, as the case may be, on or after such respective dates against each of the Company and any Guarantor shall not be impaired or affected without the consent of such Holder.

Section 6.07Proceedings by Trustee. In case of an Event of Default, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are necessary to protect and enforce any of such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 6.08Remedies Cumulative and Continuing. Except as provided in the last paragraph of Section 2.06, all powers and remedies given by this Article 6 to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the Trustee or the Holders of the Notes, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the Trustee or of any Holder of any of the Notes to exercise any right or power accruing upon any Default or Event of Default shall impair any such right or power, or shall be construed to be a waiver of any such Default or Event of Default or any acquiescence therein; and, subject to the provisions of Section 6.06, every power and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the Holders.

Section 6.09Direction of Proceedings and Waiver of Defaults by Holders. The Holders of the Specified Percentage of the aggregate principal amount of the Notes at the time outstanding determined in accordance with Section 8.04 shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to the Notes;provided,however, that (a) such direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. The Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any actions or forbearances by a Holder are prejudicial to other Holders) or that would involve the Trustee in personal liability. Prior to taking any action hereunder, the Trustee shall be entitled to indemnification and/or security from the Holders satisfactory to it against all losses, liabilities, or expenses caused by taking or not taking such action. The Holders of the Specified Percentage in aggregate principal amount of the Notes at the time outstanding (determined in accordance with Section

8.04 and including waivers obtained in connection with a repurchase of, or tender or exchange offer for, the Notes) may on behalf of the Holders of all of the Notes waive any past Default or Event of Default hereunder and its consequences except (i) a default in the payment of accrued and unpaid interest, if any, on, or the principal (including any Redemption Price and any Fundamental Change Repurchase Price) of, the Notes when due that has not been cured, (ii) a failure by the Company to pay, deliver or cause to deliver, as the case may be, the consideration due upon exchange of the Notes or (iii) a default in respect of a covenant or provision hereof which under Article 10 cannot be modified or amended without the consent of each Holder of an outstanding Note affected. Upon any such waiver the Company, the Guarantors, the Trustee and the Holders of the Notes shall be restored to their former positions and rights hereunder; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever any Default or Event of Default hereunder shall have been waived as permitted by this Section 6.09, said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed to have been cured and to be not continuing.

Section 6.10Notice of Defaults.

(a) Upon the Company becoming aware of the occurrence of any Event of Default or the occurrence of any event, circumstance or condition that following notice or the lapse of time provided for under Section 6.01 would constitute an Event of Default, the Company shall as soon as possible, and in any event within 15 Business Days after becoming aware of any such occurrence, file with the Trustee written notice of such Event of Default or event, circumstance or condition.

(b) The Trustee shall, within 90 days after any Event of Default for which it receives written notice as provided for in Section 6.10(a), send to all Holders as the names and addresses of such Holders appear upon the Note Register (as provided under Section 313(c) of the Trust Indenture Act, if applicable), notice of such Event of Default or other event, circumstance or condition, unless such Event of Default or other event, circumstance or condition shall have been cured or waived before the giving of such notice.

Section 6.11Undertaking to Pay Costs. All parties to this Indenture agree, and each Holder of any Note by its acceptance thereof shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant;provided that the provisions of this Section 6.11 (to the extent permitted by law) shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Notes at the time outstanding determined in accordance with Section 8.04, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or accrued and unpaid interest, if any, on any Note (including, but not limited to, the Redemption Price and the Fundamental Change Repurchase Price with respect to the Notes

being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or to any suit for the enforcement of the right to exchange any Note in accordance with the provisions of Article 14.

ARTICLE 7

CONCERNINGTHE TRUSTEE

Section 7.01Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver of all Events of Default that may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs;provided that if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under this Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity and/or security satisfactory to it against any loss, liability or expense that might be incurred by it in compliance with such request or direction.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(a) prior to the occurrence of an Event of Default and after the curing or waiving of all Events of Default that may have occurred:

(i) the duties and obligations of the Trustee shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations as are specifically set forth in this Indenture and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(ii) in the absence of bad faith or willful misconduct on the part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case of any such certificates or opinions that by any provisions hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of any mathematical calculations or other facts stated therein);

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer or Officers of the Trustee, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(c) the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the written direction of the Holders of not less than the Specified Percentage of the aggregate principal amount of the Notes at the time outstanding determined as provided in Section 8.04 relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture;

(d) whether or not therein provided, every provision of this Indenture relating to the conduct or affecting the liability of, or affording protection to, the Trustee shall be subject to the provisions of this Section 7.01;

Subject to the provisions of Section 11.02, neither the Company nor any Guarantor shall consolidate with, merge with or into, or sell, convey, transfer or lease all or substantially all of their respective properties and assets to another Person, unless:

(a) the resulting, surviving or transferee Person (the “Successor Company”), if not the Company or a Guarantor, shall be a corporation organized and existing under the laws of the United States of America, any State thereof, the District of Columbia, the Republic of Ireland or Bermuda, and the Successor Company (if not the Company or a Guarantor) shall expressly assume, by supplemental indenture all of the obligations of the Company or such Guarantor, as applicable, under the Notes, this Indenture and the Guarantee, as the case may be;

(b) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing under this Indenture; and

(c) in the case of a consolidation, merger, sale, conveyance, transfer or lease involving the Company or the Subsidiary Guarantors, the Successor Company is a wholly owned Subsidiary of Iterum.

For purposes of this Section 11.01, the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of one or more Subsidiaries of Iterum to another Person, which properties and assets, if held by Iterum instead of such Subsidiaries, would constitute all or substantially all of the properties and assets of Iterum on a consolidated basis, shall be deemed to be the sale, conveyance, transfer or lease of all or substantially all of the properties and assets of Iterum to another Person. For the avoidance of doubt, any rights that may be available to the Holders pursuant to Section 15.02 shall not be waived or otherwise modified as a result of a Fundamental Change being permissible under this Section 11.01.

Section 11.02Successor Corporation to Be Substituted. In case of any such consolidation, merger, sale, conveyance, transfer or lease and upon the assumption by the Successor Company, by supplemental indenture (if required by Section 11.01), executed and delivered to the Trustee and satisfactory in form to the Trustee, of the due and punctual payment of the principal of and any accrued and unpaid interest on all of the Notes, the due and punctual delivery or payment, as the case may be, of any consideration due upon exchange of the Notes and the due and punctual performance of all of the covenants and conditions of this Indenture, the Notes and the Guarantee to be performed by the Company or the Guarantors, as applicable, such Successor Company (if not the Company or any Guarantor, as applicable) shall succeed to and, except in the case of a lease of all or substantially all of the Company’s or the Guarantors’ properties and assets, shall be substituted for the Company or the Guarantor, as applicable, with

the same effect as if it had been named herein as the party of the first part. Such Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Company any or all of the Notes issuable hereunder which theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the written order of such Successor Company instead of the Company and subject to all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or cause to be authenticated and delivered, any Notes that previously shall have been signed and delivered by the Officers of the Company to the Trustee for authentication, and any Notes that such Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this Indenture as though all of such Notes had been issued at the date of the execution hereof. In the event of any such consolidation, merger, sale, conveyance or transfer (but not in the case of a lease), upon compliance with this Article 11 the Person named as the “Company”, “Iterum” or a “Subsidiary Guarantor” in the first paragraph of this Indenture (or any successor that shall thereafter have become such in the manner prescribed in this Article 11), as applicable, may be dissolved, wound up and liquidated at any time thereafter and, except in the case of a lease, such Person shall be released from its liabilities as obligor or guarantor and (in the case of the Company) maker of the Notes and from its obligations under this Indenture, the Notes and the Guarantee, as the case may be.

In case of any such consolidation, merger, sale, conveyance, transfer or lease, such changes in phraseology and form (but not in substance) may be made in the Notes thereafter to be issued as may be appropriate.

Section 11.03Officer’s Certificate and Opinion of Counsel to Be Given to Trustee. No such consolidation, merger, sale, conveyance, transfer or lease shall be effective unless the Trustee shall receive an Officer’s Certificate and an Opinion of Counsel as conclusive evidence that any such consolidation, merger, sale, conveyance, transfer or lease and any such assumption and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with the provisions of this Article 11, and in the case of the Opinion of Counsel, that such supplemental indenture is the legal, valid and binding obligation of the relevant Successor Company.

Section 11.04.Changes of Control. Iterum shall require the ultimate beneficial owner or beneficial owners that controls or control, as the case may be, any acquiring Person or Persons, in any transaction permitted under this Indenture which constitutes a Change of Control Transaction with respect to Iterum, to guarantee the obligations of the Company and Iterum under this Indenture and the Guarantee as a condition to such transaction or series of related transactions; provided that the foregoing obligation may be waived by Holders of at least the Specified Percentage in principal amount of Notes then outstanding in accordance with this Indenture.

ARTICLE 13

GUARANTEEOF NOTES

Section 13.01Guarantee.

(a) By its execution hereof, each Guarantor acknowledges and agrees that it receives substantial benefits from the Company and the issuance of the Notes and that such Guarantor is providing its Guarantee for good and valuable consideration, including, without limitation, such substantial benefits. Accordingly, subject to the provisions of this Article 13, each Guarantor hereby fully and unconditionally guarantees as a primary principal obligation and not merely as a surety to each Holder and its successors and assigns that: (x) the principal of (including the Redemption Price and Fundamental Change Repurchase Price, if applicable), Exchange Obligations with respect to, and interest on, the Notes shall be duly and punctually paid in full and/or performed in accordance with the terms of this Indenture when due, whether at the Maturity Date, upon declaration of acceleration, upon redemption, upon required repurchase, upon exchange or otherwise, along with any interest on overdue principal, interest, and (to the extent permitted by law) interest on any interest, if any, on the Notes, (y) in case of any extension of time of payment or renewal of any Notes or any of such other obligations, the same shall be duly and punctually paid in full and/or performed in accordance with the terms of this Indenture when due or performed in accordance with the terms of the extension or renewal, whether at the Maturity Date, upon declaration of acceleration, upon redemption, upon required repurchase, upon exchange or otherwise, along with any interest on overdue principal, interest and (to the extent permitted by law) interest on any interest, if any, on the Notes. Furthermore, subject to the provisions of this Article 13, each Guarantor hereby fully and unconditionally guarantees to the Trustee and to each Holder and their respective successors and assigns that all other obligations of the Company to the Holders or the Trustee hereunder or under the Notes (including fees, expenses or other obligations) shall be promptly paid in full or performed, all in

accordance with the terms hereof, subject, however, in the case of each of the foregoing obligations set forth above in this Section 13.01, to the limitations set forth in Section 13.02 hereof (the obligations set forth in this Section 13.01 collectively, the “Guarantee Obligations”). Failing payment when due of any Guarantee Obligation for whatever reason, such Guarantor will be obligated to pay the same immediately. An Event of Default with respect to the Notes under this Indenture shall constitute an event of default under the Guarantee and shall entitle the Holders to accelerate the obligations of the Guarantors hereunder in the same manner and to the same extent as the obligations of the Company. Each Guarantor covenants and agrees, and each Holder of a Note, by such Holder’s acceptance thereof, likewise covenants and agrees, that, notwithstanding anything in this Indenture or the Notes to the contrary, the Guarantee constitutes a general unsecured obligation of each Guarantor and will be subordinate in right of payment to any Guarantor Senior Debt, it being understood that the terms of Article 18 of this Indenture shall apply to the Guarantee Obligations as if (i) such Article 18 were set forth herein in full, (ii) the term “Guarantee Obligations” were substituted for the term “Notes” appearing in such Article 18, (iii) the term “Guarantor Senior Debt” were substituted for the term “Senior Debt” appearing in such Article 18 and (iv) the term “Guarantors” were substituted for the term “Company” appearing in such Article 18.

(b) Subject to the provisions of this Article 13, each Guarantor hereby agrees that its Guarantee hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any thereof, the entry of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of such Guarantor. Each Guarantor hereby waives and relinquishes: (i) any right to require the Trustee, the Holders or the Company (each, a “Benefited Party”) to proceed against the Company or any other Person or to proceed against or exhaust any security held by a Benefited Party at any time or to pursue any other remedy in any secured party’s power before proceeding against such Guarantor; (ii) any defense that may arise by reason of the incapacity, lack of authority, death or disability of any other Person or Persons or the failure of a Benefited Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of any other Person or Persons; (iii) demand, protest and notice of any kind (except as expressly required by this Indenture), including but not limited to notice of the existence, creation or incurring of any new or additional indebtedness or obligation or of any action ornon-action on the part of such Guarantor, the Company, any Benefited Party, any creditor of such Guarantor or the Company or on the part of any other Person whomsoever in connection with any obligations the performance of which are hereby guaranteed; (iv) any defense based upon an election of remedies by a Benefited Party, including but not limited to an election to proceed against such Guarantor for reimbursement; (v) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (vi) any defense arising because of a Benefited Party’s election, in any proceeding instituted under Bankruptcy Law, of the application of Section 1111(b)(2) of the Bankruptcy Code or any similar provision (including under Bermudan or Irish law); and (vii) any defense based on any borrowing or grant of a security interest under Section 364 of the Bankruptcy Code or any similar provision (including under Bermudan or Irish law). Each Guarantor hereby

covenants that, except as otherwise provided therein, the Guarantee shall not be discharged except by payment or satisfaction, as the case may be, in full of all Guarantee Obligations, including principal and interest on the Notes and any other costs provided for under this Indenture (including as provided in Article 7).

(c) Each Guarantor as principal obligor and as a separate and independent obligation and liability from its other obligations and liabilities under this Indenture agrees to indemnify and keep indemnified each Holder and the Trustee in full and on demand in respect of the performance and discharge of the Guarantee Obligations (except where the Company’s failure to perform or discharge the Guarantee Obligations results from such Holder’s failure to comply with its obligations under the Indenture or the Trustee’s negligence or willful misconduct or the Company contesting any payment or part of a payment in good faith).

(d) If any Holder or the Trustee is required by any court or otherwise to return to either the Company or any Guarantor, or any trustee or similar official acting in relation to either the Company or such Guarantor, any amount paid by the Company or such Guarantor to the Trustee or such Holder, then the Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guarantee Obligations hereby until payment in full of all such obligations guaranteed hereby. Each Guarantor agrees that, as between it, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes hereof, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Guarantee Obligations, and (y) in the event of any acceleration of such obligations as provided in Article 6 hereof, such Guarantee Obligations (whether or not due and payable) shall forthwith become due and payable by such Guarantor for the purpose of the Guarantee.

(e) The Company and the Guarantors acknowledge that the allotment and issue of Ordinary Shares (whether upon exchange, under the terms of the Guarantee or otherwise) by Iterum will create an equivalent debt owing from the Company to Iterum. For the avoidance of doubt, upon Iterum’s causing the delivery of Ordinary Shares in respect of the Exchange Obligation, the portion of such obligation consisting of an obligation to deliver or cause to be delivered Ordinary Shares shall be deemed satisfied to the extent of the shares so delivered.

(f) The exercise by a Holder of a Note of the right to exchange that Note for Ordinary Shares (if any) in compliance with the provisions of this Indenture shall be deemed to constitute a demand for immediate repayment by each of the Company and the Guarantors of that Note.

(g) Notwithstanding anything in this Indenture to the contrary, (i) with respect to the Subsidiary Guarantors, the Guarantee Obligations only include obligations to make cash payments of amounts due in accordance with the terms of this Indenture and do not include the performance of any obligation by the Company or Iterum to issue or deliver the Notes or any Ordinary Shares; and (ii) with respect to the Subsidiary Guarantors, the Guarantee does not apply

to any liability to the extent that it would result in the Guarantee constituting unlawful financial assistance within the meaning of section 82 the Irish Companies Act 2014 (as amended).

Section 13.02Limitation of theGuarantors’ Liability; Certain Bankruptcy Events.

(a) Each Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the Guarantee Obligations of the Guarantors pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal, state or foreign law. To effectuate the foregoing intention, the Holders and the Guarantors hereby irrevocably agree that the Guarantee Obligations of the Guarantors under this Article 13 shall be limited to the maximum amount as shall, after giving effect to all other contingent and fixed liabilities of the Guarantors, result in the Guarantee Obligations of the Guarantors under the Guarantee not constituting a fraudulent transfer or conveyance.

(b) Each Guarantor hereby covenants and agrees, to the fullest extent that it may do so under applicable law, that in the event of the insolvency, examinership, bankruptcy, dissolution, liquidation or reorganization of the Company, such Guarantor shall not file (or join in any filing of), or otherwise seek to participate in the filing of, any motion or request seeking to stay or to prohibit (even temporarily) execution on the Guarantee and hereby waives and agrees not to take the benefit of any such stay of execution, whether under Section 362 or 105 of the Bankruptcy Code or otherwise.

Section 13.03Execution And Delivery. The Guarantee shall be evidenced by the execution and delivery of this Indenture or a supplement to this Indenture and no notation of the Guarantee need be endorsed on any Note. Each Guarantor hereby agrees that its Guarantee set forth in Section 13.01 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. If an Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of the Guarantors.

No later than three Business Days following the occurrence of the Mandatory Exchange Trigger Event, the Company shall or, at its written request received by the Trustee, the Trustee, in the name of and at the expense of the Company, shall deliver or cause to be delivered a notice of such Mandatory Exchange (a “Mandatory Exchange Notice”) to the Exchange Agent (if other than the Trustee) and the Holders;provided,however, that, if the Company shall give such notice, it shall also give written notice of the Mandatory Exchange to the Trustee (if the Trustee is not the Exchange Agent). The Mandatory Exchange Notice shall (i) state that the Mandatory Exchange Trigger Event has occurred, (ii) state the current Exchange Rate and the Settlement Method for the Mandatory Exchange as elected by the Company (and, in the case of an election of Combination Settlement, the Specified Dollar Amount per $1,000 principal amount of Notes) and (iii) include the Exchange Date for the Mandatory Exchange, which shall be the tenth Business Day following the date of such notice.

(c)Ownership Caps.

(i) Notwithstanding anything herein to the contrary, Iterum shall not issue to any Holder of a Specified Note, and no Holder of a Specified Note may acquire, a number of Ordinary Shares upon exchange of a Note and the Company shall not otherwise deliver any Ordinary Shares pursuant hereto, to the extent that, (1) upon such exchange, the number of Ordinary Shares then beneficially owned by the Holder and its Affiliates and any other Persons or entities whose beneficial ownership of Ordinary

Shares would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including any shares held by any “group” of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to exchange, convert, exercise or purchase similar to the limitation set forth herein) would exceed 19.99% of the total number of Ordinary Shares issued and outstanding or (2) such issuance, when aggregated with any other Ordinary Shares theretofore or simultaneously therewith issued to or otherwise beneficially owned by the Holder and its Affiliates and any other Persons or entities whose beneficial ownership of Ordinary Shares would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including any shares held by any “group” of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to acquire securities that have limitations on the right to exchange, convert, exercise or purchase similar to the limitation set forth herein) would otherwise result in a “change of control” of Iterum within the meaning of Nasdaq Listing Rule 5635(b) ((a) and (b), together, the “Individual Ownership Cap”); except that such limitation shall not apply in the event that Iterum obtains all necessary Shareholder Approvals for such exchange. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and applicable regulations of the Commission, and the percentage held by the Holder shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act.

(ii) Notwithstanding anything herein to the contrary, Iterum shall not issue to any Holder of a Specified Note, and no such Holder may acquire, a number of Ordinary Shares upon exchange of a Note and the Company shall not otherwise deliver any Ordinary Shares pursuant hereto, to the extent that the issuance of such Ordinary Shares would, together with any other issuance of Ordinary Shares by Iterum to any Holders of Specified Notes upon the exchange of all Specified Notes, exceed 19.99% of the issued and outstanding Ordinary Shares immediately prior to the initial issuance of the Specified Notes (the “Aggregate Ownership Cap”), except that such limitation shall not apply in the event that Iterum (a) obtains all necessary Shareholder Approvals for the issuances of Ordinary Shares in excess of the Aggregate Ownership Cap or (b) obtains a waiver from the Nasdaq Stock Market LLC of all applicable listing rules requiring such stockholder approval. Until one of the exceptions in clauses (a) or (b) of the proceeding sentence applies and has been satisfied, upon exchange of a Specified Note the Holder thereof shall in no event, subject to the terms of Section 14.01 and Section 14.02, be entitled to receive a number of Ordinary Shares (determined in the aggregate for all such exchanges of a Specified Note by such Holder) in excess of (x) [•]³ (subject to adjustment in the event of any stock dividend, stock split, combination or other similar recapitalization) multiplied by (y) the quotient obtained by dividing the principal amount of such Specified Note by the initial aggregate principal of all Specified Notes immediately following their original issuance.

(iii) Notwithstanding anything herein to the contrary, Iterum shall not issue to any Holder of a Specified Note, and no such Holder may acquire, a number of Ordinary Shares upon exchange of a Note and the Company shall not otherwise deliver any Ordinary Shares pursuant hereto, to the extent that the issuance of such Ordinary Shares would, together with any other issuance of Ordinary Shares by Iterum to any Holders of Specified Notes upon the exchange of all Specified Notes, exceed the Available Shares (the “Available Shares Ownership Cap”), except that such limitation shall not apply in the event that Iterum obtains the Authorized Shares Approval. Until the exception in the proceeding sentence applies and has been satisfied, upon exchange of a Specified Note the Holder thereof shall in no event, subject to the terms of Section 14.01 and Section 14.02, be entitled to receive a number of Ordinary Shares (determined in the aggregate for all such exchanges of a Specified Note by such Holder) in excess of (x) the Available Shares multiplied by (y) the quotient obtained by dividing the principal amount of such Specified Note by the initial aggregate principal of all Specified Notes immediately following their original issuance.

(iv) Notwithstanding anything herein to the contrary, if the Company shall have chosen Physical Settlement or Combination Settlement pursuant to Section 14.02(a) and the exchange of a Note would otherwise result in its Holder exceeding the Individual Ownership Cap, the Aggregate Ownership Cap or the Available Shares Ownership Cap, such that the number of shares issuable upon exchange of such Note is limited by Section 14.01(c)(i), Section 14.01(c)(ii) or Section 14.01(c)(iii), the applicable portion of the Note that is not exchanged as result of such limitations shall remain outstanding in accordance with the terms of this Indenture and the obligation of Iterum to exchange such Note and issue the shares that would have resulted in the Holder exceeding the Individual Ownership Cap, the Aggregate Ownership Cap or the Available Shares Ownership Cap shall not be extinguished, and Iterum and the Trustee shall as promptly as practicable exchange such Notes and deliver to the Holder such number of shares that would have resulted in the Holder exceeding the Individual Ownership Cap, the Aggregate Ownership Cap or the Available Shares Ownership Cap following such time as the issuance of such shares would not exceed the Individual Ownership Cap, the Aggregate Ownership Cap or the Available Shares Ownership Cap; provided, however, that in the case of an issuance of shares that would result in the Holder exceeding the Individual Ownership Cap, such Holder shall provide written notice to the Company, Iterum and the Trustee that such delivery would not result in the Holder exceeding the Individual Ownership Cap and shall provide the Company, Iterum and the Trustee with any certifications, representations and other documentation reasonably requested by the Company, Iterum or the Trustee in connection therewith. In no event shall the Company nor the Guarantors have any obligation to pay to the Holder in cash the value of the Ordinary Shares that would otherwise be issuable upon an exchange in the absence of the Individual Ownership Cap, the Aggregate Ownership Cap or the Available Shares Ownership Cap; provided that any Note not so exchanged as a result of the application of the foregoing shall remain outstanding in accordance with the terms of this Indenture.

(v) Notwithstanding anything herein to the contrary, in the event a Holder of a Physical Note (a) notifies the Company, Iterum and the Trustee after delivery of a Mandatory Exchange Notice including the Company’s election of Physical Settlement or Combination Settlement and prior to completion of the Mandatory Exchange that such Holder would be obligated to make a mandatory offer for the entire issued share capital of Iterum pursuant to Rule 9 of the Irish Takeover Rules as a result of the issuance of Ordinary Shares to the Holder upon a Mandatory Exchange and (b) provides the Company, Iterum and the Trustee with any certifications, representations and other documentation reasonably requested by the Company, Iterum or the Trustee in connection therewith, Iterum shall issue to such Holder the maximum number of Ordinary Shares that may be issued to such Holder without obligating such Holder to make such a mandatory offer and shall not exchange Ordinary Shares for the remaining portion of such Note; provided, however, that the obligation of Iterum to issue any such additional Ordinary Shares shall not be extinguished, and Iterum shall make such delivery as promptly as practicable after any such Holder gives notice to the Company, Iterum and the Trustee that such delivery would not result in the Holder being obligated to make a mandatory offer for the entire issued share capital of Iterum pursuant to Rule 9 of the Irish Takeover Rules.

(vi) Notwithstanding anything herein to the contrary, in the event a Beneficial Holder (a) notifies the Company, Iterum and the Trustee after delivery of a Mandatory Exchange Notice including the Company’s election of Physical Settlement or Combination Settlement and prior to completion of the Mandatory Exchange that such Beneficial Holder would be obligated to make a mandatory offer for the entire issued share capital of Iterum pursuant to Rule 9 of the Irish Takeover Rules as a result of the issuance of Ordinary Shares to the Beneficial Holder upon a Mandatory Exchange, (b) provides the Company, Iterum and the Trustee with any certifications, representations and other documentation reasonably requested by the Company, Iterum or the Trustee in connection therewith and (c) requests a Physical Note in lieu of a beneficial interest in a Global Note, the Company shall promptly cause a Physical Note to be issued to the Beneficial Holder in accordance with Section 2.05(c), and shall treat such Beneficial Holder as though such Beneficial Holder were a Holder who had delivered a notice pursuant to Section 14.01(c)(v).

(vii) For the avoidance of doubt, any Notes or portion thereof not exchanged for Ordinary Shares as result of the provisions of this Section 14.01(c) shall continue to be held by the Holders thereof, and none of the rights, obligations and other terms under the Notes, this Indenture or the Guarantee with respect to such Notes shall be deemed amended or otherwise modified in connection with such exchange.

(viii) Any Ordinary Shares issued upon exchange of a Specified Note shall not be voted in connection with, or counted in support of, the Shareholder Approval.

Section 14.02Exchange Procedure; Settlement Upon Exchange.

(a) Subject to Section 14.01(c), this Section 14.02 and Section 14.07(a), upon exchange of any Note, the Company shall, at its election, pay or deliver, as the case may be, to the exchanging Holder, in respect of each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged, cash (“Cash Settlement”), Ordinary Shares, together with cash, if applicable, in lieu of delivering any fractional Ordinary Share in accordance with subsection (i) of this Section 14.02 (“Physical Settlement”) or a combination of cash and Ordinary Shares, together with cash, if applicable, in lieu of delivering any fractional Ordinary Share in accordance with subsection (i) of this Section 14.02 (“Combination Settlement”), as set forth in this Section 14.02.

(i) All exchanges for which the relevant Exchange Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date, and all exchanges for which the relevant Exchange Date occurs on or after October 31, 2024, shall be settled using the same Settlement Method.

(ii) Except for any exchanges for which the relevant Exchange Date occurs after the Company’s issuance of a Redemption Notice with respect to the Notes but prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date, and any exchanges for which the relevant Exchange Date occurs on or after October 31, 2024, the Company shall use the same Settlement Method for all exchanges with the same Exchange Date, but the Company shall not have any obligation to use the same Settlement Method with respect to exchanges that occur on different Exchange Dates.

(iii) If, in respect of any Exchange Date (or the period described in the fourth immediately succeeding set of parentheses, as the case may be), the Company elects to deliver a written notice (the “Settlement Notice”) of the relevant Settlement Method in respect of such Exchange Date (or such period, as the case may be), the Company shall deliver such Settlement Notice to exchanging Holders (with a copy to the Trustee and Exchange Agent) no later than the close of business on the Trading Day immediately following the relevant Exchange Date (or, in the case of any exchanges of any Notes for which the relevant Exchange Date occurs (A) on or after the date of issuance of a Redemption Notice with respect to the Notes and prior to the close of business on the second Scheduled Trading Day immediately preceding the related Redemption Date in such Redemption Notice or (B) on or after October 31, 2024, no later than the close of business on the Business Day immediately preceding October 31, 2024);provided, however, that with respect to a Mandatory Exchange, the Mandatory Exchange Notice shall constitute the Settlement Notice. If the Company does not elect a Settlement Method prior to the deadline set forth in the immediately preceding sentence, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement and the Company shall be deemed to have elected Combination Settlement in respect of its Exchange Obligation, and the Specified Dollar Amount per $1,000 of principal of and

accrued but unpaid interest on the Notes being exchanged shall be equal to $1,000. Such Settlement Notice shall specify the relevant Settlement Method and in the case of an election of Combination Settlement, the relevant Settlement Notice shall indicate the Specified Dollar Amount per $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged. If the Company delivers a Settlement Notice electing Combination Settlement in respect of its Exchange Obligation but does not indicate a Specified Dollar Amount per $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged in such Settlement Notice, the Specified Dollar Amount per $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged shall be deemed to be $1,000.

(iv) The cash, Ordinary Shares or combination of cash and Ordinary Shares in respect of any exchange of Notes (the “Settlement Amount”) shall be computed as follows:

(A) if the Company elects to satisfy its Exchange Obligation in respect of such exchange by Physical Settlement, the Company shall cause to be delivered to the exchanging Holder in respect of each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged a number of Ordinary Shares equal to the Exchange Rate in effect on the Exchange Date;

(B) if the Company elects to satisfy its Exchange Obligation in respect of such exchange by Cash Settlement, the Company shall pay to the exchanging Holder in respect of each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged cash in an amount equal to the sum of the Daily Exchange Values for each of the 30 consecutive Trading Days during the related Observation Period; and

(C) if the Company elects (or is deemed to have elected) to satisfy its Exchange Obligation in respect of such exchange by Combination Settlement, the Company shall pay or cause to be delivered, as the case may be, in respect of each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged, a Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 30 consecutive Trading Days during the related Observation Period.

(v) The Daily Settlement Amounts (if applicable) and the Daily Exchange Values (if applicable) shall be determined by the Company promptly following the last day of the Observation Period. Promptly after such determination of the Daily Settlement Amounts or the Daily Exchange Values, as the case may be, and the amount of cash payable in lieu of delivering any fractional Ordinary Share, the Company shall notify the Trustee and the Exchange Agent (if other than the Trustee) of the Daily Settlement Amounts or the Daily Exchange Values, as the case may be, and the amount of cash payable in lieu of delivering fractional Ordinary Shares. The Trustee and the Exchange Agent (if other than the Trustee) shall have no responsibility for any such determination.

(b) Subject to Section 14.02(e), before any Holder of a Note shall be entitled to exchange a Note as set forth above, such Holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in effect at that time and (ii) in the case of a Physical Note (1) complete, manually sign and deliver an irrevocable notice to the Exchange Agent as set forth in the Form of Notice of Exchange (or a facsimile thereof) (a “Notice of Exchange”) at the Corporate Trust Office or the office of the Exchange Agent (if other than the Trustee) and state in writing therein the principal amount of Notes to be exchanged and the name or names (with addresses) in which such Holder wishes the certificate or certificates for any Ordinary Shares to be delivered upon settlement of the Exchange Obligation to be registered, (2) surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate endorsement and transfer documents), at the Corporate Trust Office or the office of the Exchange Agent (if other than the Trustee), (3) if required, furnish appropriate endorsements and transfer documents and (4) with respect to any exchange by a Holder of a Specified Note, provide the Company, Iterum and the Trustee with any certifications, representations and other documentation reasonably requested by the Company, Iterum or the Trustee to demonstrate the Holder’s compliance with Section 14.01(c);provided, however, that the Notice of Exchange in clause (1) shall not be required in the case of a Mandatory Exchange. The Trustee (and, if different, the Exchange Agent) shall notify the Company of any voluntary exchange pursuant to this Article 14 on the Exchange Date for such exchange. No Notice of Exchange with respect to any Notes may be surrendered by a Holder thereof if (i) such Holder has also delivered a Fundamental Change Repurchase Notice to the Company in respect of such Notes and has not validly withdrawn such Fundamental Change Repurchase Notice in accordance with Section 15.03 or (ii) the Company has delivered a Mandatory Exchange Notice.

If more than one Note shall be surrendered for exchange at one time by the same Holder, the Exchange Obligation with respect to such Notes shall be computed on the basis of the aggregate of principal of and accrued but unpaid interest on the Notes so surrendered (or specified portions thereof to the extent permitted thereby).

(c) A Note shall be deemed to have been exchanged immediately prior to the close of business on the date (the “Exchange Date”) that the Holder has complied with the requirements set forth in subsection (b) above (or, in the case of a Mandatory Exchange, the Exchange Date set forth in the Mandatory Exchange Notice). Except as provided in Section 14.07(a), the Company shall pay or cause to be delivered, as the case may be, the consideration due in respect of the Exchange Obligation (i) on the second Business Day immediately following the relevant Exchange Date, if the Company elects to use Physical Settlement, or (ii) on the second Business Day immediately following the last Trading Day of the relevant Observation Period, in the case of any other Settlement Method (the “Exchange Settlement Date”). Subject to Section 14.01(c), if any Ordinary Shares are due to exchanging Holders, the Company shall issue or cause to be issued, and deliver to the Exchange Agent or to such Holder, or such Holder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for the full number of Ordinary Shares to which such Holder shall be entitled in satisfaction of the Company’s Exchange Obligation.

(d) In case any Note shall be surrendered for partial exchange, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the Note so surrendered a new Note or Notes in authorized denominations in an aggregate principal amount equal to the unexchanged portion of the surrendered Note, without payment of any service charge by the exchanging Holder but, if required by the Company or Trustee, with payment of a sum sufficient to cover any documentary, stamp or similar issue or transfer tax or similar governmental charge required by law or that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange being different from the name of the Holder of the old Notes surrendered for such exchange.

(e) If a Holder submits a Note for exchange, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the issuance of any Ordinary Shares upon exchange, unless the tax is due because the Holder requests such shares to be issued in a name other than the Holder’s name, in which case the Holder shall pay that tax. The Exchange Agent may refuse to deliver the certificates representing the Ordinary Shares being issued in a name other than the Holder’s name until the Trustee receives a sum sufficient to pay any tax that is due by such Holder in accordance with the immediately preceding sentence.

(f) Upon the exchange of an interest in a Global Note, the Trustee, or the Custodian at the direction of the Trustee, shall make a notation on such Global Note as to the reduction in the principal amount represented thereby. The Company shall notify the Trustee in writing of any exchange of Notes effected through any Exchange Agent other than the Trustee.

(g) Upon exchange, a Holder shall not receive any separate cash payment for accrued and unpaid interest, if any. The Company’s settlement of the full Exchange Obligation shall be deemed to satisfy in full its obligation to pay the principal amount of the Note and accrued and unpaid interest, if any, to, but not including, the relevant Exchange Date. As a result, accrued and unpaid interest, if any, to, but not including, the relevant Exchange Date shall be deemed to be paid in full rather than canceled, extinguished or forfeited. Upon an exchange of Notes for a combination of cash and Ordinary Shares, any accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such exchange.

(h) The Person in whose name the certificate for any Ordinary Shares delivered upon exchange is registered shall be treated as a shareholder of record as of the close of business on the relevant Exchange Date (if the exchange is settled by Physical Settlement) or the last Trading Day of the relevant Observation Period (if the Company elects to satisfy the related Exchange Obligation by Combination Settlement), as the case may be. Upon an exchange of Notes, such Person shall no longer be a Holder of such Notes surrendered for exchange.

(i) The Company shall not issue any fractional Ordinary Share upon exchange of the Notes and shall instead pay cash in lieu of delivering any fractional Ordinary Share issuable upon exchange based on the Daily VWAP on the relevant Exchange Date (in the case of Physical Settlement) or based on the Daily VWAP on the last Trading Day of the relevant Observation Period (in the case of Combination Settlement). For each Note surrendered for exchange, if the Company has elected (or is deemed to have elected) Combination Settlement, the full number of

shares that shall be issued upon exchange thereof shall be computed on the basis of the aggregate Daily Settlement Amounts for the relevant Observation Period and any fractional shares remaining after such computation shall be paid in cash.

Section 14.03Intentionally Omitted.

Section 14.04Adjustment of Exchange Rate. The Exchange Rate shall be adjusted from time to time by the Company if any of the following events occurs, except that the Company shall not make any adjustments to the Exchange Rate if Holders of the Notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of the Ordinary Shares and solely as a result of holding the Notes, in any of the transactions described in this Section 14.04, without having to exchange their Notes, as if they held a number of Ordinary Shares equal to the Exchange Rate per each $1,000 of principal of and accrued but unpaid interest on the Notes held by such Holder.

(a) If Iterum exclusively issues Ordinary Shares as a dividend or distribution on Ordinary Shares, or if Iterum effects a share split or share combination, the Exchange Rate shall be adjusted based on the following formula:

LOGO

where,


CR₀	=	the Exchange Rate in effect immediately prior to the open of business on theEx-Dividend Date of such dividend or distribution, or immediately prior to the open of business on the Effective Date of such share split or share combination, as applicable;

CR’	=	the Exchange Rate in effect immediately after the open of business on suchEx-Dividend Date or Effective Date;

OS₀	=	the number of Ordinary Shares outstanding immediately prior to the open of business on suchEx-Dividend Date or Effective Date (before giving effect to any such dividend, distribution, split or combination); and

OS’	=	the number of Ordinary Shares outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this Section 14.04(a) shall become effective immediately after the open of business on theEx-Dividend Date for such dividend or distribution, or immediately after the open of business on the Effective Date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this Section 14.04(a) is declared but not so paid or made, or any share split or combination of the type described in this Section 14.04(a) is announced but the outstanding Ordinary Shares are not split or combined, as

the case may be, the Exchange Rate shall be immediately readjusted, effective as of the date Iterum’s Board of Directors determines not to pay such dividend or distribution, or not to split or combine the outstanding Ordinary Shares, as the case may be, to the Exchange Rate that would then be in effect if such dividend or distribution had not been declared or such share split or combination had not been announced.

(b) If Iterum issues to all or substantially all holders of the Ordinary Shares any rights, options or warrants (other than a Rights Offering) entitling them, for a period of not more than 45 calendar days after the announcement date of such issuance, to subscribe for or purchase Ordinary Shares at a price per share that is less than the average of the Last Reported Sale Prices of the Ordinary Shares for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of such issuance, the Exchange Rate shall be increased based on the following formula:

LOGO

where,


CR₀	=	the Exchange Rate in effect immediately prior to the open of business on theEx-Dividend Date for such issuance;

CR’	=	the Exchange Rate in effect immediately after the open of business on suchEx-Dividend Date;

OS₀	=	the number of Ordinary Shares outstanding immediately prior to the open of business on suchEx-Dividend Date;

X	=	the total number of Ordinary Shares issuable pursuant to such rights, options or warrants; and

Y	=	the number of Ordinary Shares equal to the aggregate price payable to exercise such rights, options or warrants,divided by the average of the Last Reported Sale Price per Ordinary Share over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this Section 14.04(b) shall be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on theEx-Dividend Date for such issuance. To the extent that Ordinary Shares are not delivered after the expiration of such rights, options or warrants, the Exchange Rate shall be decreased to the Exchange Rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of Ordinary Shares actually delivered. If such rights, options or warrants are not so issued, the Exchange Rate shall be decreased to the Exchange Rate that would then be in effect if

suchEx-Dividend Date for such issuance had not occurred. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate will be made (other than with respect to the Company’s right to readjust the Exchange Rate).

For purposes of this Section 14.04(b), in determining whether any rights, options or warrants entitle the holders of the Ordinary Shares to subscribe for or purchase Ordinary Shares at less than such average of the Last Reported Sale Price per Ordinary Share for the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such Ordinary Shares, there shall be taken into account any consideration received by Iterum for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by Iterum’s Board of Directors in good faith.

(c) If Iterum distributes shares of its Capital Stock, evidences of its indebtedness, other assets or property of Iterum or rights, options or warrants to subscribe for, purchase or otherwise acquire its Capital Stock or other securities of Iterum, to all or substantially all holders of the Ordinary Shares, excluding (i) dividends, distributions or issuances as to which an adjustment was effected pursuant to Section 14.04(a) or Section 14.04(b), (ii) dividends or distributions paid exclusively in cash as to which the provisions set forth in Section 14.04(d) shall apply, (iii) distributions of Reference Property in a transaction described in Section 14.07, (iv) Spin-Offs as to which the provisions set forth below in this Section 14.04(c) shall apply or (v) a Rights Offering (any of such shares of Capital Stock, evidences of indebtedness, other assets or property or rights, options or warrants to subscribe for, purchase or otherwise acquire Capital Stock or other securities, the “Distributed Property”), then the Exchange Rate shall be increased based on the following formula:

LOGO

where,


CR₀	=	the Exchange Rate in effect immediately prior to the open of business on theEx-Dividend Date for such distribution;

CR’	=	the Exchange Rate in effect immediately after the open of business on suchEx-Dividend Date;

SP₀	=	the average of the Last Reported Sale Price per Ordinary Share over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding theEx-Dividend Date for such distribution; and


FMV		=		the fair market value (as determined by Iterum’s Board of Directors in good faith) of the Distributed Property with respect to each outstanding Ordinary Share on theEx-Dividend Date for such distribution.

Any increase made under the portion of this Section 14.04(c) above shall become effective immediately after the open of business on theEx-Dividend Date for such distribution. If such distribution is not so paid or made, the Exchange Rate shall be decreased to the Exchange Rate that would then be in effect if such distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate will be made (other than with respect to the Company’s right to readjust the Exchange Rate).

Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, in respect of each $1,000 of principal of and accrued but unpaid interest on the Notes held by such Holder, at the same time and upon the same terms as holders of the Ordinary Shares receive the Distributed Property, the amount and kind of Distributed Property such Holder would have received if such Holder owned a number of Ordinary Shares equal to the Exchange Rate in effect on theEx-Dividend Date for the distribution. If the Board of Directors determines the “FMV” (as defined above) of any distribution for purposes of this Section 14.04(c) by reference to the actual or when-issued trading market for any securities, it shall in doing so consider the prices in such market over the 10 consecutive Trading Day period ending on, and including, the Trading Day immediately preceding theEx-Dividend Date for such distribution.

With respect to an adjustment pursuant to this Section 14.04(c) where there has been a payment of a dividend or other distribution on the Ordinary Shares of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a Subsidiary or other business unit of Iterum, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange (a “Spin-Off”), the Exchange Rate shall be increased based on the following formula:

LOGO

where,


CR₀	=	the Exchange Rate in effect immediately prior to the end of the Valuation Period;

CR’	=	the Exchange Rate in effect immediately after the end of the Valuation Period;

FMV₀	=	the average of the Last Reported Sale Price per share or unit of the Capital Stock or similar equity interest distributed to holders of the Ordinary Shares applicable to one Ordinary Share (determined by reference to the definition of Last Reported Sale Price as set forth in Section 1.01 as if references therein to Ordinary Shares were to such Capital Stock or similar equity interest) over the first 10 consecutive Trading


		Day period beginning on, and including, theEx-Dividend Date of theSpin-Off (the “Valuation Period”); and

MP₀	=	the average of the Last Reported Sale Price per Ordinary Share over the Valuation Period.

The increase to the Exchange Rate under the preceding paragraph shall occur at the close of business on the last Trading Day of the Valuation Period;provided that (i) in respect of any exchange of Notes for which Physical Settlement is applicable, if the relevant Exchange Date occurs during the Valuation Period, the reference to “10” in the portion of this Section 14.04(c) related to Spin-Offs shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, theEx-Dividend Date for suchSpin-Off to, and including, such Exchange Date in determining the Exchange Rate and (ii) in respect of any exchange of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such exchange and within the Valuation Period, the reference to “10” in this Section 14.04(c) related to Spin-Offs shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, theEx-Dividend Date for suchSpin-Off to, and including, such Trading Day in the relevant Observation Period for purposes of determining the Exchange Rate as of such Trading Day. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate will be made (other than with respect to the Company’s right to readjust the Exchange Rate).

For purposes of this Section 14.04(c) (and subject in all respect to Section 14.11), rights, options or warrants distributed by Iterum to all holders of the Ordinary Shares entitling them to subscribe for or purchase shares of Iterum’s Capital Stock, including Ordinary Shares (either initially or under certain circumstances), which rights, options or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such Ordinary Shares; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of Ordinary Shares, shall be deemed not to have been distributed for purposes of this Section 14.04(c) (and no adjustment to the Exchange Rate under this Section 14.04(c) will be required) until the occurrence of the earliest Trigger Event, whereupon such rights, options or warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Exchange Rate shall be made under this Section 14.04(c). If any such right, option or warrant, including any such existing rights, options or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights, options or warrants become exercisable to purchase different securities, evidences of indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution andEx-Dividend Date with respect to new rights, options or warrants with such rights (in which case the existing rights, options or warrants shall be deemed to terminate and expire on such date without exercise by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger Event or other event (of the type described in the immediately preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Exchange Rate under this Section 14.04(c) was made, (1) in the case of any such rights, options

or warrants that shall all have been redeemed or purchased without exercise by any holders thereof, upon such final redemption or purchase (x) the Exchange Rate shall be readjusted as if such rights, options or warrants had not been issued and (y) the Exchange Rate shall then again be readjusted to give effect to such distribution, deemed distribution or Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or purchase price received by a holder or holders of Ordinary Shares with respect to such rights, options or warrants (assuming such holder had retained such rights, options or warrants), made to all holders of Ordinary Shares as of the date of such redemption or purchase, and (2) in the case of such rights, options or warrants that shall have expired or been terminated without exercise by any holders thereof, the Exchange Rate shall be readjusted as if such rights, options and warrants had not been issued.

For purposes of Section 14.04(a), Section 14.04(b) and this Section 14.04(c), if any dividend or distribution to which this Section 14.04(c) is applicable also includes one or both of:

(A) a dividend or distribution of Ordinary Shares to which Section 14.04(a) is applicable (the “Clause A Distribution”); or

(B) a dividend or distribution of rights, options or warrants to which Section 14.04(b) is applicable (the “Clause B Distribution”),

then, in either case, (1) such dividend or distribution, other than the Clause A Distribution and the Clause B Distribution, shall be deemed to be a dividend or distribution to which this Section 14.04(c) is applicable (the “Clause C Distribution”) and any Exchange Rate adjustment required by this Section 14.04(c) with respect to such Clause C Distribution shall then be made, and (2) the Clause A Distribution and Clause B Distribution shall be deemed to immediately follow the Clause C Distribution and any Exchange Rate adjustment required by Section 14.04(a) and Section 14.04(b) with respect thereto shall then be made, except that, if determined by the Company (I) the“Ex-Dividend Date” of the Clause A Distribution and the Clause B Distribution shall be deemed to be theEx-Dividend Date of the Clause C Distribution and (II) any Ordinary Shares included in the Clause A Distribution or Clause B Distribution shall be deemed not to be “outstanding immediately prior to the open of business on suchEx-Dividend Date or Effective Date” within the meaning of Section 14.04(a) or “outstanding immediately prior to the open of business on suchEx-Dividend Date” within the meaning of Section 14.04(b).

(d) If any cash dividend or distribution is made to all or substantially all holders of the Ordinary Shares, the Exchange Rate shall be adjusted based on the following formula:

LOGO

where,


CR₀		=		the Exchange Rate in effect immediately prior to the open of business on theEx-Dividend Date for such dividend or distribution;


CR’	=	the Exchange Rate in effect immediately after the open of business on theEx-Dividend Date for such dividend or distribution;

SP₀	=	the Last Reported Sale Price per Ordinary Share on the Trading Day immediately preceding theEx-Dividend Date for such dividend or distribution; and

C	=	the amount in cash per share the Company distributes to all or substantially all holders of the Ordinary Shares.

Any increase pursuant to this Section 14.04(d) shall become effective immediately after the open of business on theEx-Dividend Date for such dividend or distribution. If such dividend or distribution is not so paid, the Exchange Rate shall be decreased, effective as of the date Iterum’s Board of Directors determines not to make or pay such dividend or distribution, to be the Exchange Rate that would then be in effect if such dividend or distribution had not been declared. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate will be made (other than with respect to the Company’s right to readjust the Exchange Rate).

Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each Holder of a Note shall receive, for each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged, at the same time and upon the same terms as holders of Ordinary Shares, the amount of cash that such Holder would have received if such Holder owned a number of Ordinary Shares equal to the Exchange Rate on theEx-Dividend Date for such cash dividend or distribution.

(e) If Iterum or any of its Subsidiaries make a payment in respect of a tender or exchange offer for the Ordinary Shares, to the extent that the cash and value of any other consideration included in the payment per share of the Ordinary Shares exceeds the average of the Last Reported Sale Price per Ordinary Share over the 10 consecutive Trading Day period commencing on, and including, the Trading Day immediately following the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Exchange Rate shall be increased based on the following formula:

LOGO

where,


CR₀	=	the Exchange Rate in effect immediately prior to the close of business on the 10th Trading Day immediately following, and including, the Trading Day immediately following the date such tender or exchange offer expires;

CR’	=	the Exchange Rate in effect immediately after the close of business on the 10th Trading Day immediately following, and including, the Trading Day immediately following the date such tender or exchange offer expires;


AC	=	the aggregate value of all cash and any other consideration (as determined by the Board of Directors in good faith) paid or payable for Ordinary Shares purchased in such tender or exchange offer;

OS₀	=	the number of Ordinary Shares outstanding immediately prior to the date such tender or exchange offer expires (prior to giving effect to the purchase of all Ordinary Shares accepted for purchase or exchange in such tender or exchange offer);

OS’	=	the number of Ordinary Shares outstanding immediately after the date such tender or exchange offer expires (after giving effect to the purchase of all Ordinary Shares accepted for purchase or exchange in such tender or exchange offer); and

SP’	=	the average of the Last Reported Sale Price per Ordinary Share over the 10 consecutive Trading Day period commencing on, and including, the Trading Day immediately following the date such tender or exchange offer expires.

The increase to the Exchange Rate under this Section 14.04(e) shall occur at the close of business on the 10th Trading Day immediately following, and including, the Trading Day immediately following the date such tender or exchange offer expires;provided that (i) in respect of any exchange of Notes for which Physical Settlement is applicable, if the relevant Exchange Date occurs during the 10 Trading Days immediately following, and including, the Trading Day next succeeding the expiration date of any tender or exchange offer, references to “10” or “10th” in this Section 14.04(e) shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the expiration date of such tender or exchange offer to, and including, such Exchange Date in determining the Exchange Rate and (ii) in respect of any exchange of Notes for which Cash Settlement or Combination Settlement is applicable, for any Trading Day that falls within the relevant Observation Period for such exchange and within the 10 Trading Days immediately following, and including, the Trading Day immediately following the expiration date of any tender or exchange offer, references to “10” or “10th” in this Section 14.04(e) shall be deemed replaced with such lesser number of Trading Days as have elapsed from, and including, the Trading Day next succeeding the date such tender or exchange offer expires to, and including, such Trading Day in the relevant Observation Period for purposes of determining the Exchange Rate as of such Trading Day. For the avoidance of doubt, if the application of the foregoing formula would result in a decrease in the Exchange Rate, no adjustment to the Exchange Rate will be made (other than with respect to the Company’s right to readjust the Exchange Rate).

(f)Anti-Dilution Protection.

(i)Adjustment of Exchange Rate Upon Issuance of Additional Ordinary Shares. In the event Iterum shall at any time after the First Issue Date issue Additional Ordinary Shares (including Additional Ordinary Shares deemed to be issued pursuant to Section 14.04(f)(iv)), without consideration or for consideration per share less than the Exchange Price in effect immediately prior to such issuance or deemed issuance, then,

unless the Exchange Rate has been adjusted pursuant to Sections 14.04(a)-(e) above for such event, the Exchange Rate shall be increased based on the following formula:

LOGO

where,


CR₀ =		the Exchange Rate in effect immediately prior to such issuance or deemed issuance of Additional Ordinary Shares;

CR’ =		the Exchange Rate in effect immediately after such issuance or deemed issuance of Additional Ordinary Shares;

OS₀ =		the number of Ordinary Shares outstanding immediately prior to such issuance or deemed issuance of Additional Ordinary Shares (treating for this purpose as outstanding all Ordinary Shares issuable upon exercise of Options outstanding immediately prior to such issuance or deemed issuance or upon conversion or exchange of Convertible Securities outstanding (assuming exercise of any outstanding Options therefor) immediately prior to such issue);

Y =		the number of Ordinary Shares that would have been issued if such Additional Ordinary Shares had been issued or deemed issued at a price per share equal to the Exchange Price in effect immediately prior to such issuance or deemed issuance of Additional Ordinary Shares (determined by dividing the aggregate consideration received by Iterum in respect of such issue by such Exchange Price); and

X =		the number of such Additional Ordinary Shares issued in such transaction.

The increase to the Exchange Rate under this Section 14.04(f) shall occur at the close of business on the fourth Trading Day immediately following the issuance of Additional Ordinary Shares. No adjustment in the Exchange Rate shall be made under this Section 14.04(f) as the result of the issuance or deemed issuance of Additional Ordinary Shares if Iterum receives written notice from all Holders agreeing that no such adjustment shall be made as the result of the issuance or deemed issuance of such Additional Ordinary Shares.

(ii)Determination of Consideration. For purposes of this Section 14.04(f), the consideration received by Iterum for the issuance or deemed issuance of any Additional Ordinary Shares shall be computed as follows:

(A)Cash and Property: Such consideration shall:

(1) insofar as it consists of cash, be computed at the aggregate amount of cash received by Iterum, excluding amounts paid or payable for accrued interest;

(2) insofar as it consists of property other than cash, be computed at the fair market value thereof at the time of such issue, as determined in good faith by the Board of Directors of the Company; and

(3) in the event Additional Ordinary Shares are issued together with other shares or securities or other assets of Iterum for consideration which covers both, be the proportion of such consideration so received, computed as provided in clauses (1) and (2) above, as determined in good faith by the Board of Directors of the Company.

(B)Options and Convertible Securities. The consideration per share received by Iterum for Additional Ordinary Shares deemed to have been issued pursuant to Section 14.04(f)(iv), relating to Options and Convertible Securities, shall be determined by dividing:

(1) The total amount, if any, received or receivable by Iterum as consideration for the issue of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such consideration) payable to Iterum upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(2) the maximum number of Ordinary Shares (as set forth in the instruments relating thereto, without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities.

(iii)Multiple Closing Dates. In the event Iterum shall issue on more than one date Additional Ordinary Shares that are a part of one transaction or a series of related transactions and that would result in an adjustment to the Exchange Rate pursuant to the terms of Section 14.04(f)(i), and such issuance dates occur within a period of no more than ninety (90) days from the first such issuance to the final such issuance, then, upon the election of the Board of Directors of the Company prior to the date of the first such issuance, no adjustment shall be made until the final such issuance, and upon the final

such issuance, the Exchange Rate shall be adjusted to give effect to all such issuances as if they occurred on the date of the first such issuance (and without giving effect to any additional adjustments as a result of any such subsequent issuances within such period).

(iv)Deemed Issue of Additional Ordinary Shares.

(A) If Iterum at any time or from time to time after the First Issue Date shall issue any Options or Convertible Securities (excluding Options or Convertible Securities which are themselves Exempted Securities), then the maximum number of Ordinary Shares (as set forth in the instrument relating thereto, assuming the satisfaction of any conditions to exercisability, convertibility or exchangeability but without regard to any provision contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Ordinary Shares issued as of the time of such issue.

(B) If the terms of any Option or Convertible Security, the issuance of which resulted in an adjustment to the Exchange Rate pursuant to the terms of Section 14.04(f)(i) are revised as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase or decrease in the number of Ordinary Shares issuable upon the exercise, conversion and/or exchange of any such Option or Convertible Security or (2) any increase or decrease in the consideration payable to Iterum upon such exercise, conversion and/or exchange, then, effective upon such increase or decrease becoming effective, the Exchange Rate computed upon the original issue of such Option or Convertible Security shall be readjusted to such Exchange Rate as would have obtained had such revised terms been in effect upon the original date of issuance of such Option or Convertible Security.

(C) If the terms of any Option or Convertible Security (excluding Options or Convertible Securities which are themselves Exempted Securities), the issuance of which did not result in an adjustment to the Exchange Rate pursuant to the terms of Section 14.04(f)(i) (either because the consideration per share (determined pursuant to Section 14.04(f)(ii)) of the Additional Ordinary Shares subject thereto was equal to or greater than the Exchange Price then in effect, or because such Option or Convertible Security was issued before the First Issue Date), are revised after the First Issue Date as a result of an amendment to such terms or any other adjustment pursuant to the provisions of such Option or Convertible Security (but excluding automatic adjustments to such terms pursuant to anti-dilution or similar provisions of such Option or Convertible Security) to provide for either (1) any increase in the number of Ordinary Shares issuable upon the exercise, conversion or exchange of any such Option or

Convertible Security or (2) any decrease in the consideration payable to Iterum upon such exercise, conversion or exchange, then such Option or Convertible Security, as so amended or adjusted, and the Additional Ordinary Shares subject thereto (determined in the manner provided in Section 14.04(f)(iv)(A) shall be deemed to have been issued effective upon such increase or decrease becoming effective.

(D) Upon the expiration or termination of any unexercised Option or unconverted or unexchanged Convertible Security (or portion thereof) which resulted (either upon its original issuance or upon a revision of its terms) in an adjustment to the Exchange Rate pursuant to the terms of Section 14.04(f)(i), the Exchange Rate shall be readjusted to such Exchange Rate as would have obtained had such Option or Convertible Security (or portion thereof) never been issued.

(E) If the number of Ordinary Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to Iterum upon such exercise, conversion and/or exchange, is calculable at the time such Option or Convertible Security is issued or amended but is subject to adjustment based upon subsequent events, any adjustment to the Exchange Rate provided for in this Section 14.04(f)(iv) shall be effected at the time of such issuance or amendment based on such number of shares or amount of consideration without regard to any provisions for subsequent adjustments (and any subsequent adjustments shall be treated as provided in clauses (B) and (C) of this Section 14.04(f)(iv)). If the number of Ordinary Shares issuable upon the exercise, conversion and/or exchange of any Option or Convertible Security, or the consideration payable to Iterum upon such exercise, conversion and/or exchange, cannot be calculated at all at the time such Option or Convertible Security is issued or amended, any adjustment to the Exchange Rate that would result under the terms of this Section 14.04(f)(iv) at the time of such issuance or amendment shall instead be effected at the time such number of shares and/or amount of consideration is first calculable (even if subject to subsequent adjustments), assuming for purposes of calculating such adjustment to the Exchange Rate that such issuance or amendment took place at the time such calculation can first be made.

(g) Notwithstanding this Section 14.04 or any other provision of this Indenture or the Notes, if an Exchange Rate adjustment becomes effective on anyEx-Dividend Date, and a Holder that has exchanged its Notes on or after suchEx-Dividend Date and on or prior to the related Record Date would be treated as the record holder of the Ordinary Shares as of the related Exchange Date as described under Section 14.02(h) based on an adjusted Exchange Rate for suchEx-Dividend Date, then, notwithstanding the Exchange Rate adjustment provisions in this Section 14.04, the Exchange Rate adjustment relating to suchEx-Dividend Date shall not be made for such exchanging Holder. Instead, such Holder shall be treated as if such Holder were

the record owner of the Ordinary Shares on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

(h) Except as otherwise expressly stated herein, the Company shall not adjust the Exchange Rate for the issuance of Ordinary Shares or any securities convertible into or exchangeable for Ordinary Shares or the right to purchase Ordinary Shares or such convertible or exchangeable securities.

(i) In addition to those adjustments required by clauses (a), (b), (c), (d), (e) and (f) of this Section 14.04, and to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of Iterum’s securities are then listed, Iterum from time to time may increase the Exchange Rate by any amount for a period of at least 20 Business Days if Iterum’s Board of Directors determines that such increase would be in the Company’s and/or Iterum’s best interest. In addition, to the extent permitted by applicable law and subject to the applicable rules of any exchange on which any of Iterum’s securities are then listed, the Company may (but is not required to) increase the Exchange Rate to avoid or diminish any income tax to holders of Ordinary Shares or rights to purchase Ordinary Shares in connection with a dividend or distribution of Ordinary Shares (or rights to acquire Ordinary Shares) or similar event. Whenever the Exchange Rate is increased pursuant to either of the preceding two sentences, the Company shall send to the Holder of each Note at its last address appearing on the Note Register a notice of the increase at least 15 days prior to the date the increased Exchange Rate takes effect, and such notice shall state the increased Exchange Rate and the period during which it will be in effect.

(j) Notwithstanding anything to the contrary in this Article 14, the Exchange Rate shall not be adjusted:

(i) upon the issuance of any Ordinary Shares pursuant to any present or future plan providing for the reinvestment of dividends or any interest payable on Iterum’s securities and the investment of additional optional amounts in Ordinary Shares under any plan;

(ii) upon the issuance of any Ordinary Shares or rights, options or warrants to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by Iterum or any of Iterum’s Subsidiaries;

(iii) upon the issuance of any Ordinary Shares pursuant to any right, option, warrant or exercisable, exchangeable or convertible security not described in clause (ii) of this subsection and outstanding as of the date the Notes were first issued;

(iv) upon the repurchase of Ordinary Shares pursuant to an open-market share repurchase program or otherbuy-back transaction that is not a tender offer or exchange offer of the nature described in Section 14.04(e);

(v) solely for a change in the par value of the Ordinary Shares; or

(vi) for accrued and unpaid interest, if any, on the Notes.

(k) The Company shall not be required to make an adjustment pursuant to clauses (a), (b), (c), (d), (e) or (f) of this Section 14.04 unless such adjustment would result in a change of at least 1% of the then effective Exchange Rate. However, the Company shall carry forward any adjustment that the Company would otherwise have to make and take that adjustment into account in any subsequent adjustment. Notwithstanding the foregoing, all such carried-forward adjustments shall be made with respect to the Notes (i) in connection with any subsequent adjustment to the Exchange Rate of at least 1% of the Exchange Rate (when such carried-forward adjustments are taken into account) and (ii) (x) on the Exchange Date for any Notes (in the case of Physical Settlement) and (y) on each Trading Day of any Observation Period (in the case of Cash Settlement or Combination Settlement). All calculations and other determinations under this Article 14 shall be made by the Company and shall be made to the nearestone-ten thousandth (1/10,000) of a share.

(l) Whenever the Exchange Rate is adjusted as herein provided, the Company shall promptly file with the Trustee (and the Exchange Agent if not the Trustee) an Officer’s Certificate setting forth the Exchange Rate after such adjustment and setting forth a brief statement of the facts requiring such adjustment. Unless and until a Responsible Officer of the Trustee shall have received such Officer’s Certificate, the Trustee shall not be deemed to have knowledge of any adjustment of the Exchange Rate and may assume without inquiry that the last Exchange Rate of which it has knowledge is still in effect. Promptly after delivery of such certificate, the Company shall prepare a notice of such adjustment of the Exchange Rate setting forth the adjusted Exchange Rate and the date on which each adjustment becomes effective and shall send such notice of such adjustment of the Exchange Rate to each Holder at its last address appearing on the Note Register of this Indenture. Failure to deliver such notice shall not affect the legality or validity of any such adjustment.

(m) For purposes of this Section 14.04, the number of Ordinary Shares at any time outstanding shall not include Ordinary Shares held in the treasury of Iterum so long as Iterum does not pay any dividend or make any distribution on Ordinary Shares held in the treasury of Iterum, but shall include Ordinary Shares issuable in respect of scrip certificates issued in lieu of fractions of Ordinary Shares.

Section 14.05Adjustments of Prices.Whenever any provision of this Indenture requires the Company to calculate the Last Reported Sale Prices, the Daily VWAPs, the Daily Exchange Values or the Daily Settlement Amounts over a span of multiple days (including without limitation, an Observation Period), the Company shall make appropriate adjustments to each to account for any adjustment to the Exchange Rate that becomes effective, or any event requiring an adjustment to the Exchange Rate where theEx-Dividend Date of the event occurs, at any time during the period when the Last Reported Sale Prices, the Daily VWAPs, the Daily Exchange Values or the Daily Settlement Amounts are to be calculated.

Section 14.06Shares to Be Fully Paid. Subject to the valid passing of the Authorized Shares Approval by the requisite majority of shareholders at a duly convened shareholder

meeting, Iterum shall, and the Company shall cause Iterum to, reserve, free from preemptive rights, out of Iterum’s authorized but unissued shares or shares held in treasury, sufficient Ordinary Shares to provide for exchange of the Notes from time to time as such Notes are presented for exchange (assuming that at the time of computation of such number of shares, all such Notes would be exchanged by a single Holder and that Physical Settlement is applicable).

Section 14.07Effect of Recapitalizations, Reclassifications and Changes of the Ordinary Shares.

(a) In the case of:

(i) any recapitalization, reclassification or change of the Ordinary Shares (other than changes resulting from a subdivision or combination),

(ii) any consolidation, merger or combination involving Iterum,

(iii) any sale, lease or other transfer to a third party of the consolidated assets of Iterum and its Subsidiaries substantially as an entirety or

(iv) any statutory share exchange,

in each case, as a result of which the Ordinary Shares would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a “Specified Transaction”), then, subject to Section 15.02 to the extent such Specified Transaction is a Fundamental Change, at and after the effective time of such Specified Transaction, the right to exchange each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged shall be changed into a right to exchange such principal amount of Notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of Ordinary Shares equal to the Exchange Rate immediately prior to such Specified Transaction would have owned or been entitled to receive (the “Reference Property”, with each “unit of Reference Property” meaning the kind and amount of Reference Property that a holder of one Ordinary Share is entitled to receive) upon such Specified Transaction and, prior to or at the effective time of such Specified Transaction, the Company and the Guarantors and/or the successor or purchasing Person, as the case may be, shall execute with the Trustee a supplemental indenture permitted under Section 10.01(m) providing for such change in the right to exchange each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged;provided,however, that at and after the effective time of the Specified Transaction (A) the Company or the successor or purchasing Person, as the case may be, shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon exchange of Notes in accordance with Section 14.02 and (B) (I) any amount payable in cash upon exchange of the Notes in accordance with Section 14.02 shall continue to be payable in cash, (II) any Ordinary Shares that the Company would have been required to deliver upon exchange of the Notes in accordance with Section 14.02 shall instead be deliverable in the amount and type of Reference Property that a holder of that number of Ordinary Shares would have received in such Specified

Transaction and (III) the Daily VWAP shall be calculated based on the value of a unit of Reference Property.

If the Specified Transaction causes the Ordinary Shares to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of shareholder election), then (i) the Reference Property into which the Notes will be exchangeable shall be deemed to be the weighted average of the types and amounts of consideration actually received by the holders of Ordinary Shares, and (ii) the unit of Reference Property for purposes of the immediately preceding paragraph shall refer to the consideration referred to in clause (i) attributable to one Ordinary Share. If the holders of Ordinary Shares receive only cash in such Specified Transaction, then for all exchanges that occur after the effective date of such Specified Transaction (A) the consideration due upon exchange of each $1,000 of principal of and accrued but unpaid interest on the Notes being exchanged shall be solely cash in an amount equal to the Exchange Rate in effect on the Exchange Date,multiplied by the price paid per Ordinary Share in such Specified Transaction and (B) the Company shall satisfy the Exchange Obligation by paying cash to exchanging Holders on the second Business Day immediately following the relevant Exchange Date. The Company shall notify Holders, the Trustee and the Exchange Agent (if other than the Trustee) of such weighted average as soon as practicable after such determination is made.

Such supplemental indenture described in the second immediately preceding paragraph shall provide for adjustments that shall be as nearly equivalent as is possible to the adjustments provided for in this Article 14. If, in the case of any Specified Transaction, the Reference Property includes shares of stock, securities or other property or assets (including cash or any combination thereof) of a Person other than the Company, the Guarantors and/or the successor or purchasing corporation, as the case may be, in such Specified Transaction, then such supplemental indenture shall also be executed by such other Person and shall contain such additional provisions to protect the interests of the Holders of the Notes as the Board of Directors shall reasonably consider necessary by reason of the foregoing, including the provisions providing for the purchase rights set forth in Article 15.

(b) When the Company or the Guarantors execute a supplemental indenture pursuant to subsection (a) of this Section 14.07, the Company shall promptly file with the Trustee an Officer’s Certificate briefly stating the reasons therefor, the kind or amount of cash, securities or property or asset that will comprise a unit of Reference Property after any such Specified Transaction, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and an Opinion of Counsel stating that all conditions precedent have been complied with, and shall promptly send notice thereof to all Holders. The Company shall cause notice of the execution of such supplemental indenture to be sent to each Holder, at its address appearing on the Note Register provided for in this Indenture, within 20 days after execution thereof. Failure to deliver such notice shall not affect the legality or validity of such supplemental indenture.

(c) Neither the Company nor the Guarantors shall become a party to any Specified Transaction unless its terms are consistent with this Section 14.07. None of the foregoing

provisions shall affect the right of a holder of Notes to exchange its Notes into cash, Ordinary Shares or a combination of cash and Ordinary Shares, as applicable, as set forth in Section 14.01 and Section 14.02 prior to the effective date of such Specified Transaction.

(d) The above provisions of this Section shall similarly apply to successive Specified Transactions.

(e) Upon the consummation of any Specified Transaction, references to “Ordinary Shares” shall be deemed to refer to any Reference Property that constitutes Common Equity after giving effect to such Specified Transaction.

Section 14.08Certain Covenants. (a) Each of the Company and Iterum covenants that all Ordinary Shares issued upon exchange of Notes will be newly issued shares or treasury shares, duly authorized, fully paid and not subject to any calls for any additional payments(non-assessable) and free from all taxes, liens and charges with respect to the issuance thereof.

(b) Iterum covenants that, if any Ordinary Shares to be provided for the purpose of exchange of Notes hereunder require registration with or approval of any governmental authority under any federal or state law before such Ordinary Shares may be validly issued upon exchange, Iterum will, to the extent then permitted by the rules and interpretations of the Commission, secure such registration or approval, as the case may be.

(c) Iterum further covenants that if at any time the Ordinary Shares shall be listed on any national securities exchange or automated quotation system Iterum will list and keep listed, so long as the Ordinary Shares shall be so listed on such exchange or automated quotation system, any Ordinary Shares issuable upon exchange of the Notes.

Section 14.09Responsibility of Trustee. The Trustee and any other Exchange Agent shall not at any time be under any duty or responsibility to any Holder to determine the Exchange Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment (including any increase) of the Exchange Rate, or with respect to the nature or extent or calculation of any such adjustment when made, or with respect to the method employed, or herein or in any supplemental indenture provided to be employed, in making the same. The Trustee and any other Exchange Agent shall not be accountable with respect to the validity or value (or the kind or amount) of any Ordinary Shares, or of any securities, property or cash that may at any time be issued or delivered upon the exchange of any Note; and the Trustee and any other Exchange Agent make no representations with respect thereto. Neither the Trustee nor any Exchange Agent shall be responsible for any failure of the Company to issue, transfer or deliver any Ordinary Shares or stock certificates or other securities or property or cash upon the surrender of any Note for the purpose of exchange or to comply with any of the duties, responsibilities or covenants of the Company contained in this Article. Without limiting the generality of the foregoing, neither the Trustee nor any Exchange Agent shall be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture entered into pursuant to Section 14.07 relating either to the kind or amount of shares of stock or securities or property (including cash) receivable by Holders upon the exchange of their

Notes after any event referred to in such Section 14.07 or to any adjustment to be made with respect thereto, but, subject to the provisions of Section 7.01, may accept (without any independent investigation) as conclusive evidence of the correctness of any such provisions, and shall be protected in conclusively relying upon, the Officer’s Certificate and Opinion of Counsel (which the Company shall be obligated to file with the Trustee prior to the execution of any such supplemental indenture) with respect thereto. Neither the Trustee nor the Exchange Agent shall be responsible for determining whether any event contemplated by Section 14.01 has occurred that makes the Notes eligible for exchange or no longer eligible therefor until the Company has delivered to the Trustee and the Exchange Agent the notices referred to in Section 14.01 with respect to the commencement or termination of such exchange rights, on which notices the Trustee and the Exchange Agent may conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Exchange Agent immediately after the occurrence of any such event or at such other times as shall be provided for in Section 14.01. The parties agree that all notices to the Trustee or the Exchange Agent under this Article 14 must be in writing.

Section 14.10Notice to Holders Prior to Certain Actions. In case of any:

(a) action by the Company, Iterum or one of their Subsidiaries that would require an adjustment in the Exchange Rate pursuant to Section 14.04 or Section 14.11 (other than Section 14.04(f));

(b) Specified Transaction; or

(c) voluntary or involuntary dissolution, liquidation orwinding-up of the Company, the Guarantors or any of their respective Subsidiaries;

then, in each case (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Exchange Agent (if other than the Trustee) and to be sent to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 20 days prior to the applicable date hereinafter specified, a notice stating (i) the date on which a record is to be taken for the purpose of such action by the Company, the Guarantors or one of their Subsidiaries or, if a record is not to be taken, the date as of which the holders of Ordinary Shares of record are to be determined for the purposes of such action by the Company, the Guarantors or one of their Subsidiaries, or (ii) the date on which such Specified Transaction, dissolution, liquidation orwinding-up is expected to become effective or occur, and the date as of which it is expected that holders of Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for securities or other property deliverable upon such Specified Transaction, dissolution, liquidation orwinding-up.

In case of any action by Iterum that would require an adjustment in the Exchange Rate pursuant to Section 14.04(f), then (unless notice of such event is otherwise required pursuant to another provision of this Indenture), the Company shall cause to be filed with the Trustee and the Exchange Agent (if other than the Trustee) and to be mailed to each Holder at its address appearing on the Note Register, as promptly as possible but in any event at least 10 days

100

following the date on which the Additional Ordinary Shares were issued (or deemed to be issued), a notice stating the date on which such issuance occurred.

Failure to give any of the forgoing notices, or any defect therein, shall not affect the legality or validity of such action by the Company, the Guarantors or one of their Subsidiaries, Specified Transaction, dissolution, liquidation,winding-up or issuance of Additional Ordinary Shares.

Section 14.11Shareholder Rights Plans. If Iterum has a shareholder rights plan in effect upon exchange of the Notes, each Ordinary Shares, if any, delivered upon such exchange shall be entitled to receive the appropriate number of rights, if any, and the certificates representing the Ordinary Shares issued upon such exchange shall bear such legends, if any, in each case as may be provided by the terms of any such shareholder rights plan, as the same may be amended from time to time. However, if, prior to any exchange of Notes, the rights have separated from the Ordinary Shares in accordance with the provisions of the applicable shareholder rights plan so that the Holders would not be entitled to receive any rights in respect of Ordinary Shares, if any, issuable upon exchange of the Notes, the Exchange Rate shall be adjusted at the time of separation as if Iterum distributed to all or substantially all holders of the Ordinary Shares Distributed Property as provided in Section 14.04(c), subject to readjustment in the event of the expiration, termination or redemption of such rights.

ARTICLE 15

REPURCHASEOF NOTES

Section 15.01Intentionally Omitted.

Section 15.02Repurchaseat Option of Holders Upon a Fundamental Change. (a) If a Fundamental Change occurs at any time prior to the Interest Record Date, each Holder shall have the right, at such Holder’s option, to require the Company to repurchase for cash all of such Holder’s Notes, or any portion thereof that is equal to a minimum of $1,000 principal amount or a multiple of $1,000 in excess thereof, on the date (the “Fundamental Change Repurchase Date”) specified by the Company that is not less than 20 calendar days or more than 35 calendar days following the date of the Fundamental Change Company Notice at a repurchase price equal to (i) with respect to a Fundamental Change that is not a Liquidation Event, the Change of Control Price or (ii) with respect to a Fundamental Change that is a Liquidation Event, 100% of the principal amount thereof,plus, in each case, any accrued and unpaid interest thereon to, but excluding, the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”).

(b) Repurchases of Notes under this Section 15.02 shall be made, at the option of the Holder thereof, upon:

(i) delivery to the Paying Agent by a Holder of a duly completed notice (the “Fundamental Change Repurchase Notice”) in the form set forth in Attachment 2 to the Form of Note attached hereto as Exhibit A, if the Notes are Physical Notes, or in compliance with the Depositary’s procedures for surrendering interests in Global Notes,

Subject to receipt of funds by the Paying Agent, payment for the Notes to be redeemed shall be made on the Redemption Date for such Notes. The Paying Agent shall, promptly after such payment and upon written demand by the Company, return to the Company any funds in excess of the Redemption Price.

The Company covenants and agrees, and each Holder of a Note, whether upon original issue or upon transfer, assignment or exchange thereof, by such Holder’s acceptance thereof, likewise covenants and agrees, that, notwithstanding anything in this Indenture or the Notes to the contrary, the indebtedness evidenced by the Notes and the payment of the principal of (and premium, if any) and interest on each and all of the Notes are hereby expressly made subordinate and junior in right of payment to the prior payment in full in cash of all Senior Debt, whether outstanding at the date of this Indenture or thereafter incurred, to the extent and in the manner provided in this Indenture.

Section 18.02Payment Over of Proceeds Upon Dissolution, Etc. In the event of (a) any insolvency or bankruptcy case or proceeding, or any receivership, liquidation, reorganization or other similar case or proceeding in connection therewith, relative to the Company, any Guarantor or to their respective creditors, as such, or to their respective assets, or (b) any liquidation, dissolution or other winding up of the Company or any Guarantor, whether voluntary or involuntary and whether or not involving insolvency or bankruptcy, or (c) any assignment for the benefit of creditors or any other marshalling of assets and liabilities of the Company or any Guarantor, then and in any such event the holders of Senior Debt shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Debt (including any interest accruing thereon after the commencement of any such case or proceeding), or provision shall be made for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt, before the Holders of the Notes are entitled to receive any payment on account of principal of (or premium, if any), interest or other amounts due on the Notes, and to that end the holders of Senior Debt shall be entitled to receive, for application to the payment thereof, any payment or distribution of any kind or character, whether in cash, property or securities, including any such payment or distribution

114

which may be payable or deliverable by reason of the payment of any other indebtedness of the Company or any Guarantor being subordinated to the payment of the Notes, which may be payable or deliverable in respect of the Notes in any such case, proceeding, dissolution, liquidation or other winding up event.

In the event that, notwithstanding the foregoing provisions of this Section, the Trustee or the Holder of any Note shall have received any payment or distribution of assets of the Company or any Guarantor of any kind or character in respect of the Notes, whether in cash, property or securities, including any such payment or distribution which may be payable or deliverable by reason of the payment of any other indebtedness of the Company or any Guarantor being subordinated to the payment of the Notes, before all Senior Debt is paid in full or payment thereof provided for, and if such fact shall, at or prior to the time of such payment or distribution, have been made known to the Trustee in accordance with the terms of Section 18.10 hereof or, as the case may be, such Holder, subject to the terms of Section 18.10 hereof, then and in such event such payment or distribution shall be paid over or delivered forthwith by the Trustee or such Holder to the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other Person making payment or distribution of assets of the Company or any Guarantor for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt. Any taxes that have been withheld or deducted from any payment or distribution in respect of the Notes, or any taxes that ought to have been withheld or deducted from any such payment or distribution that have been remitted to the relevant taxing authority, shall not be considered to be an amount that the Trustee or the Holder of any Note receives for purposes of this Section 18.02.

For purposes of this Article 18 only, the words “cash, property or securities” shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation or other entity, provided for by a plan of reorganization or readjustment which are subordinated in right of payment to all Senior Debt which may at the time be outstanding to substantially the same extent as, or to a greater extent than, the Notes are so subordinated as provided in this Article 18.

Section 18.03Prior Payment to Senior Debt Upon Acceleration of Notes.In the event that any Notes are declared due and payable before their Maturity Date, the holders of Senior Debt shall be entitled to receive payment in full of all amounts due or to become due on or in respect of all Senior Debt or provision shall be made for such payment in cash, before the Holders of the Notes are entitled to receive any payment (including any payment which may be payable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Notes) by the Company on account of the principal of (or premium, if any) or interest or other amounts due on the Notes or on account of the purchase or other acquisition of Notes. In the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holder of any Note prohibited by the foregoing provisions of this Section, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee in accordance with the terms of Section 18.10 hereof or, as the case may be, such Holder, subject to the terms of Section 18.10 hereof, then and in such event such payment shall

115

be paid over and delivered to the Company for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt.

Section 18.04No Payment When Senior Debt in Default. In the event and during the continuation of any default in the payment of principal of (or premium, if any), interest or other amounts due on any Senior Debt beyond any applicable grace period with respect thereto, or in the event that any event of default with respect to any Senior Debt shall have occurred and be continuing permitting the holders of such Senior Debt (or a trustee on behalf of the holders thereof) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable, unless and until such event of default shall have been waived in writing and any such declaration and its consequences shall have been rescinded or annulled, or in the event that any judicial proceeding shall be pending with respect to any such default in payment or event of default, or in the event that any event of default with respect to any Senior Debt would result from any payments of the Notes, then no payments (including principal payments, interest payments or, to the extent applicable, any payment which may be payable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Note) shall be made by the Company or any Guarantor on the Notes or on account of the purchase or other acquisition of Notes.

In the event that, notwithstanding the foregoing, the Company or any Guarantor shall make any payment to the Trustee or the Holder of any Note prohibited by the provisions of this Section 18.04, and if such fact shall, at or prior to the time of such payment, have been made known to the Trustee in accordance with the terms of Section 18.10 hereof or, as the case may be, such Holder, subject to the terms of Section 18.10 hereof, then and in such event such payment shall be paid over and delivered to the Company for application to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all Senior Debt in full, after giving effect to any concurrent payment or distribution to or for the holders of Senior Debt. The provisions of this Section shall not apply to any payment with respect to which Section 18.02 would be applicable.

Section 18.05Payment Permitted in Certain Situations. Nothing contained in this Article 18 or elsewhere in this Indenture or in any of the Notes shall prevent, at any time except during the pendency of any case, proceeding, dissolution, liquidation or other winding up, assignment for the benefit of creditors or other marshalling of assets and liabilities of the Company or any Guarantor referred to in Section 18.02 or under the conditions described in Section 18.03 or Section 18.04, (a) the Company from making payments on account of the principal of (or premium, if any) or interest or other amounts due on the Notes, or on account of the purchase or other acquisition of Notes, including pursuant to any Optional Redemption in accordance with Article 16, or (b) the application by the Trustee of any money deposited with it hereunder to the payment of or on account of the principal of (and premium, if any) or interest or other amounts due on the Notes or the retention of such payment by the Holders, if, at the time of such application by the Trustee, it has not received the notice and Company Order required under Section 18.10 hereof.

116

Section 18.06Subrogation to Rights of Holders of Senior Debt. Subject to the payment in full of all Senior Debt or the provision for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Debt, the Holders of the Notes shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Debt pursuant to the provisions of this Article 18 (equally and ratably with the holders of indebtedness of the Company which by its express terms is subordinated to indebtedness of the Company to substantially the same extent as the Notes are subordinated to the Senior Debt and is entitled to like rights of subrogation) to the rights of the holders of such Senior Debt to receive payments and distributions of cash, property and securities applicable to the Senior Debt to the extent that the principal of (and premium, if any) and interest are payable under this Indenture and the Notes. For purposes of such subrogation, no payments or distributions to the holders of the Senior Debt of any cash, property or securities to which the Holders of the Notes or the Trustee would be entitled except for the provisions of this Article 18, and no payments over pursuant to the provisions of this Article 18 to the holders of Senior Debt by Holders of the Notes or the Trustee, shall, as among the Company, its creditors other than holders of Senior Debt and the Holders of the Notes, be deemed to be a payment or distribution by the Company to or on account of the Senior Debt.

Section 18.07Provisions Solely to Define Relative Rights. The provisions of this Article 18 are and are intended solely for the purpose of defining the relative rights of the Holders of the Notes on the one hand and the holders of Senior Debt on the other hand. Nothing contained in this Article 18 is intended to or shall (i) impair, as between the Company and the Holders of the Notes, the obligation of the Company to pay to the Holders of the Notes the principal of (and premium, if any) and interest on the Notes as and when the same shall become due and payable in accordance with their terms or prevent the Trustee or the Holder of any Note from exercising all rights and remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights of the holders of Senior Debt to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder in accordance with this Article 18, (ii) enhance the rights of the Holders of the Notes to the principal of (and premium, if any) and interest on the Notes in accordance with their terms, or (iii) cause any additional principal or interest on the Notes, or other amounts, to be due and payable to the Holders of the Notes.

Section 18.08Trustee to Effectuate Subordination. Each Holder of a Note by such Holder’s acceptance thereof authorizes and directs the Trustee on such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article 18 and appoints the Trustee as such Holder’sattorney-in-fact in connection therewith.

Section 18.09No Waiver of Subordination Provisions. No right of any present or future holder of any Senior Debt to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or any Guarantor or by any act or failure to act, in good faith, by any such holder, or by anynon-compliance by the Company or any Guarantor with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof any such holder may have or be otherwise charged with. Without in any way limiting the generality of the foregoing paragraph, the holders

117

of Senior Debt may, at any time and from time to time, and in their absolute discretion, change the manner, place or terms of payment or extend the time of payment of, or renew or alter, any such Senior Debt or otherwise amend or supplement in any manner such Senior Debt or any instrument evidencing the same or any agreement under which such Senior Debt is outstanding.

Section 18.10Notice to Trustee. The Company shall give prompt written notice to the Trustee of any fact known to the Company which would prohibit the making of any payment to or by the Trustee in respect of the Notes. Notwithstanding the provisions of this Article or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts which would prohibit the making of any payment to or by the Trustee in respect of the Notes, unless and until the Trustee shall have received written notice thereof from the Company and/or a holder of Senior Debt (or from any trustee therefor) as set forth below; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 7.01, shall be entitled in all respects to assume that no such facts exist. The Trustee shall make any payment(s) or distribution(s) to the holders of Senior Debt under this Article only upon (i) a Company Order notifying the Trustee of an event under Sections 18.02, 18.03 or 18.04 hereof and directing the Trustee to make such payment(s) or distribution(s) to the holders of Senior Debt or (ii) written notice from a holder of Senior Debt (or a trustee therefor) notifying the Trustee of an event under Section 18.02, 18.03 or 18.04 hereof and directing the Trustee to make such payment(s) or distribution(s) as provided for in such notice, together with a Company Order notifying the Trustee that such holder of Senior Debt (or trustee therefor) is a holder of Senior Debt and is entitled to participate in any such payment(s) or distribution(s) and directing the Trustee to make such payment(s) or distribution(s). Subject to the provisions of Section 7.01 hereof, the Trustee shall be entitled to rely upon any notice, request, instruction, direction, certificate, consent, statement, instrument, document, order or other writing received by it under this Article 18 in order to make any determination hereunder, including, without limitation, any written notice by a Person representing himself to be a holder of Senior Debt (or a trustee therefor) to establish that such notice has been given by a holder of Senior Debt (or a trustee therefor), and shall not incur liability for relying upon any such notice, request, instruction, direction, certificate, consent, statement, instrument, document, order or other writing believed by it to be genuine. The Trustee may consult with legal counsel (who may be counsel for the Company), independent accountants and other experts selected by it in connection with any notice, request, instruction, direction, certificate, consent, statement, instrument, document, order or other writing received by it under this Article 18, and shall not be liable for any action taken or not taken by it in reliance on such consultation. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Debt to participate in any payment or distribution pursuant to this Article 18, the Trustee may request the Company and/or such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 18, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.

118

Section 18.11Reliance on Judicial Order or Certificate of Liquidating Agent. Upon any payment or distribution of assets of the Company or any Guarantor referred to in this Article 18, the Trustee, subject to the provisions of Section 7.01, and the Holders of the Notes shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution, winding up or similar case or proceeding is pending, or a certificate of the trustee in bankruptcy, receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Notes, for the purpose of ascertaining whether such payment or distribution is permissible under the terms of this Article 18, including, without limitation for the purpose of ascertaining whether the Persons are entitled to participate in such payment or distribution, the holders of Senior Debt and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 18.

Section 18.12Trustee Not Fiduciary for Holders of Senior Debt. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Debt and shall not be liable to any such holders or creditors for any action or omission taken by it under the terms of this Article 18, including, without limitation, for any action or omission taken by it in reliance on any notice, request, instruction, direction, certificate, consent, statement, instrument, document, order or other writing received by it under this Article 18. With respect to the holders of Senior Debt, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article 18 and no implied covenants or obligations with respect to holders of Senior Debt shall be read into this Indenture against the Trustee. For the avoidance of doubt, (i) when acting under this Article 18, the Trustee shall have all of the rights, benefits, privileges, protections and indemnities provided to the Trustee under Article 7 of this Indenture, and (ii) the Trustee shall not have any duty to take any discretionary action or exercise any discretionary powers in acting under this Article 18.

Section 18.13Rights of Trustee as Holder of Senior Debt; Preservation of Trustee’s Rights. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 18 with respect to any Senior Debt which may at any time be held by it, to the same extent as any other holder of Senior Debt and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. Nothing in this Article 18 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.06.

Section 18.14Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been appointed by the Company and be then acting hereunder, the term “Trustee” as used in this Article 18 shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Article 18 in addition to or in place of the Trustee.

Section 18.15Modification of Subordination Provisions. Anything in Article 10 or elsewhere contained in this Indenture to the contrary notwithstanding, no modification or

119

amendment of this Indenture and no supplemental indenture shall modify the subordination provisions of this Article 18 in a manner that would adversely affect the holders of Senior Debt.

Section 18.16Senior Debt Entitled to Rely. Each holder of a Note, by accepting such Note, acknowledges and agrees that the subordination provisions contained in this Article 18 are, and are intended to be, an inducement and a consideration to each holder of the Senior Debt, whether the Senior Debt was created or acquired before or after the issuance of the Notes, to acquire or continue to hold the Senior Debt, and such holders of the Senior Debt shall have the right to rely upon this Article 18, and no amendment or modification of the provisions contained herein shall diminish the rights of such holders unless such holders shall have agreed in writing thereto. Each holder of a Note, by accepting such Note, and the Trustee, on behalf of the holders of such Notes, hereby waives the benefits, if any, of any statutory or common law rule that may permit a subordinating creditor to assert any defenses of a surety or guarantor, or that may give the subordinating creditor the right to require a senior creditor to marshal assets, and they each agree that it shall not assert any such defenses or rights.

Section 18.17Reinstatement.To the extent the payment of or distribution in respect of the Senior Debt (whether by or on behalf of the Company as proceeds of security or enforcement of any right of setoff or otherwise) is declared to be fraudulent or preferential, set aside or required to be paid to any receiver, trustee in bankruptcy, liquidating trustee, agent or similar Person under any bankruptcy, insolvency, receivership, fraudulent conveyance or similar law, then if such payment or distribution is recovered by, or paid over to, such receiver, trustee in bankruptcy, liquidating trustee, agent or similar Person, the Senior Debt or part thereof originally intended to be satisfied shall be deemed to be reinstated and outstanding as if such payment had not occurred.

Section 18.18Action by Holders of Senior Debt. The holders of the Senior Debt may, at any time and from time to time, without the consent of or notice to the Trustee or the Holders, without incurring responsibility to the Holders and without impairing or releasing the subordination provided in this Indenture or the obligations of the Holders hereunder to the holders of the Senior Debt, take any action deemed appropriate in the sole discretion of the holders of Senior Debt, including, without limitation, doing any one or more of the following:

(i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, the Senior Debt or any instrument evidencing the same or any agreement under which the Senior Debt is outstanding or secured;

(ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise secured;

(iii) release any Person liable in any manner for the collection of the Senior Debt;

(iv) exercise or refrain from exercising any rights against the Company or any other Person; and

120

(v) take any other action in the reasonable business judgment of the holders of the Senior Debt.

No such action or inaction shall impair or otherwise affect the holder of the Senior Debt’s rights under the Notes or this Indenture.

Subject to the terms and conditions of the Indenture, the Company will make all payments and deliveries in respect of the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date, the Redemption Price on the relevant Redemption Date and the principal amount and accrued and unpaid interest on the Maturity Date, as the case may be, to the Holder who surrenders a Note to a Paying Agent to collect such payments in respect of the Note.

At the office or agency of the Company referred to on the face hereof, and in the manner and subject to the limitations provided in the Indenture, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations, without payment of any service charge but, if required by the Company or Trustee, with payment of a sum sufficient to cover any transfer or similar tax that may be imposed in connection therewith as a result of the name of the Holder of the new Notes issued upon such exchange of Notes being different from the name of the Holder of the old Notes surrendered for such exchange.

The Notes shall be redeemable for cash at the Company’s option in accordance with the terms and subject to the conditions specified in the Indenture. No sinking fund is provided for the Notes.

Subject to the provisions of the Indenture, upon a Mandatory Exchange, this Note will be automatically exchanged for cash, Ordinary Shares or a combination of cash and Ordinary Shares, as applicable, at the Exchange Rate specified in the Indenture, as adjusted from time to time as provided in the Indenture.
