 Exhibit 4.4 
 EXECUTION VERSION 
 $50,000,000 

TRANSDIGM INC. 
 7.75% Senior Subordinated Notes due 2018 
 REGISTRATION RIGHTS
AGREEMENT 
 December 22, 2010 
 UBS SECURITIES LLC (“UBS”) 
 CREDIT SUISSE
SECURITIES (USA) LLC (“CS”) 
   As Representatives of the Initial Purchasers, 

c/o UBS Securities LLC 
 299 Park Avenue,

 New York, NY 10171 
 Dear Sirs:

 TransDigm Inc., a Delaware corporation (the “Issuer”), proposes to issue and sell to UBS and CS, as representatives
of the initial purchasers set forth on Schedule I hereto (the “Initial Purchasers”), upon the terms set forth in a purchase agreement (the “Purchase Agreement”), $50,000,000 aggregate principal amount of its 7.75% Senior
Subordinated Notes due 2018 (the “Initial Securities”) to be unconditionally guaranteed (the “Guarantees”) by TransDigm Group Incorporated (“TD Group”) and the subsidiaries of the Issuer listed on Schedule II hereto
(such subsidiaries are hereinafter collectively referred to as the “Company Guarantors”). TD Group and the Company Guarantors are collectively referred to herein as the “Guarantors” and the Issuer, TD Group and the Company
Guarantors are collectively referred to herein as the “Company”. The Initial Securities will be issued pursuant to an indenture, dated as of the date hereof (as supplemented from time to time, the “Indenture”), among the Issuer,
the Guarantors and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). As an inducement to the Initial Purchasers, the Company agrees with the Initial Purchasers, for the benefit of the holders of the Initial
Securities (including, without limitation, the Initial Purchasers), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively the “Holders”), as follows: 

1. Registered Exchange Offer. If the Company has not previously filed with the Securities and Exchange Commission (the
“Commission”) a registration statement (the “Exchange Offer Registration Statement”) contemplated by that certain Registration Rights Agreement, dated as of December 14, 2010, among the Company, the Initial Purchasers and
the Company Guarantors, covering the Initial Securities on an appropriate form under the Securities Act of 1933, as amended (the “Securities Act”), with respect to a proposed offer (the “Registered Exchange Offer”) to the Holders
of Transfer Restricted Securities (as defined in Section 6(d) hereof), the Company shall, at its own cost, prepare and, not later than 180 days (or if such 180th day is not a business day, the first business day thereafter) after the date of
original issue of the Initial Securities (the “Issue Date”), file with the Commission an Exchange Offer Registration Statement on an appropriate form under the Securities Act, with respect to the Registered Exchange Offer to the Holders of
Transfer Restricted Securities, who are not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer, to issue and deliver to such Holders, in exchange for the Initial Securities, an equal aggregate
principal amount of debt securities (the “Exchange Securities”) of the Issuer issued under the Indenture and identical in all material respects to the Initial Securities (except for the transfer restrictions relating to the Initial
Securities and the provisions relating to 

 
the matters described in Section 6 hereof) that would be registered under the Securities Act. The Company shall use its reasonable best efforts to cause such Exchange Offer Registration
Statement to become effective under the Securities Act within 270 days (or if the 270th day is not a business day, the first business day thereafter) after the Issue Date and shall keep the Exchange Offer Registration Statement effective for not
less than 30 days (or longer, if required by applicable law) after the date notice of the Registered Exchange Offer is mailed to the Holders (such period being called the “Exchange Offer Registration Period”). 

If the Company effects the Registered Exchange Offer, the Company will be entitled to close the Registered Exchange Offer 30 days after
the commencement thereof provided that the Company has accepted all the Initial Securities theretofore validly tendered in accordance with the terms of the Registered Exchange Offer. 

As soon as practicable after the declaration of the effectiveness of the Exchange Offer Registration Statement, the Company shall
commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Transfer Restricted Securities (as defined in Section 6(d) hereof) electing to exchange the Initial Securities for
Exchange Securities (assuming that such Holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Securities in the ordinary course of such Holder’s business and has no arrangements with any
person to participate in the distribution of the Exchange Securities and is not prohibited by any law or policy of the Commission from participating in the Registered Exchange Offer) to trade such Exchange Securities from and after their receipt
without any limitations or restrictions under the Securities Act and without material restrictions under the securities laws of the several states of the United States. 
 The Company acknowledges that, pursuant to current interpretations by the Commission’s staff of Section 5 of the Securities Act, in the absence of an applicable exemption therefrom,
(i) each Holder which is a broker-dealer electing to exchange Initial Securities, acquired for its own account as a result of market making activities or other trading activities, for Exchange Securities (an “Exchanging Dealer”), is
required to deliver a prospectus containing the information set forth in (a) Annex A hereto on the cover, (b) Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer” section,
and (c) Annex C hereto in the “Plan of Distribution” section of such prospectus in connection with a sale of any such Exchange Securities received by such Exchanging Dealer pursuant to the Registered Exchange Offer and (ii) if
the Initial Purchasers elect to sell Exchange Securities acquired in exchange for Initial Securities constituting any portion of an unsold allotment, the Initial Purchasers will be required to deliver a prospectus containing the information required
by Items 507 or 508 of Regulation S-K under the Securities Act, as applicable, in connection with such sale. 
 The Company
shall use its reasonable best efforts to keep the Exchange Offer Registration Statement effective and to amend and supplement the prospectus contained therein, in order to permit such prospectus to be lawfully delivered by all persons subject to the
prospectus delivery requirements of the Securities Act for such period of time as such persons must comply with such requirements in order to resell the Exchange Securities; provided, however, that (i) in the case where such prospectus and any
amendment or supplement thereto must be delivered by an Exchanging Dealer or the Initial Purchasers, such period shall be the lesser of 180 days and the date on which all Exchanging Dealers and the Initial Purchasers have sold all Exchange
Securities held by them (unless such period is extended pursuant to Section 3(j) below) and (ii) the Company shall make such prospectus and any amendment or supplement thereto, available to any broker-dealer for use in connection with any
resale of any Exchange Securities for a period of not less than 180 days after the consummation of the Registered Exchange Offer. 
 If, upon consummation of the Registered Exchange Offer, any Initial Purchaser holds Initial Securities acquired by it as part of its initial distribution, the Company, simultaneously with the delivery of
the Exchange Securities pursuant to the Registered Exchange Offer, shall issue and deliver to such Initial Purchaser upon the written request of such Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held
by such Initial Purchaser, an equal principal amount of debt securities of the Company issued under the Indenture and identical in all material respects (including the existence of 

  
 2 

 
restrictions on transfer under the Securities Act and the securities laws of the several states of the United States, but excluding provisions relating to the matters described in Section 6
hereof) to the Initial Securities (the “Private Exchange Securities”). The Initial Securities, the Exchange Securities and the Private Exchange Securities are herein collectively called the “Securities”. 

In connection with the Registered Exchange Offer, the Company shall: 

(a) mail, or cause to be mailed, to each Holder a copy of the prospectus forming part of the Exchange Offer Registration
Statement, together with an appropriate letter of transmittal and related documents; 
 (b) keep the Registered
Exchange Offer open for not less than 30 days (or longer, if required by applicable law) after the date notice thereof is mailed to the Holders; 
 (c) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan, The City of New York, which may be the Trustee or an affiliate of the Trustee;

 (d) permit Holders to withdraw tendered Securities at any time prior to the close of business, New York time,
on the last business day on which the Registered Exchange Offer shall remain open; and 
 (e) otherwise comply in
all material respects with all applicable laws. 
 As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall: 
 (x) accept for exchange all the Securities
validly tendered and not withdrawn pursuant to the Registered Exchange Offer and the Private Exchange; 
 (y)
deliver to the Trustee for cancellation all the Initial Securities so accepted for exchange; and 
 (z) cause the
Trustee to authenticate and deliver promptly to each Holder of the Initial Securities, Exchange Securities or Private Exchange Securities, as the case may be, equal in principal amount to the Initial Securities of such Holder so accepted for
exchange. 
 The Indenture provides that the Exchange Securities are not subject to the transfer restrictions set forth in the
Indenture and that all the Securities vote and consent together on all matters as one class. 
 Interest on each Exchange
Security and Private Exchange Security issued pursuant to the Registered Exchange Offer and in the Private Exchange will accrue from the last interest payment date on which interest was paid on the Initial Securities surrendered in exchange therefor
or, if no interest has been paid on the Initial Securities, from the Issue Date. 
 Each Holder participating in the Registered
Exchange Offer shall be required to represent to the Company that at the time of the consummation of the Registered Exchange Offer (i) any Exchange Securities received by such Holder will be acquired in the ordinary course of business,
(ii) such Holder will have no arrangements or understanding with any person to participate in the distribution of the Securities or the Exchange Securities within the meaning of the Securities Act, (iii) such Holder is not an
“affiliate,” as defined in Rule 405 of the Securities Act, of the Company or if it is an affiliate, such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable,
(iv) if such Holder is not a broker-dealer, that it is not engaged in, and does not intend to engage in, the distribution of the Exchange Securities and (v) if such Holder is a broker-dealer, that it will receive Exchange Securities for
its own account in exchange for Initial Securities that were acquired as a result of 

  
 3 

 
market-making activities or other trading activities and that it will be required to acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities.

 Notwithstanding any other provisions hereof, the Company will ensure that (i) any Exchange Offer Registration Statement
and any amendment thereto and any prospectus forming part thereof and any supplement thereto complies in all material respects with the Securities Act and the rules and regulations thereunder, (ii) any Exchange Offer Registration Statement and
any amendment thereto does not, when it becomes effective, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any
prospectus forming part of any Exchange Offer Registration Statement, and any supplement to such prospectus, does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order
to make the statements therein, in the light of the circumstances under which they were made, not misleading. 
 2. Shelf
Registration. If, (i) because of any change in law or in applicable interpretations thereof by the staff of the Commission, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof,
(ii) the Registered Exchange Offer is not consummated within 310 days of the Issue Date (or if the 310th day is not a business day, the first business day thereafter) (iii) an Initial Purchaser so requests with respect to the Initial
Securities (or the Private Exchange Securities) not eligible to be exchanged for Exchange Securities in the Registered Exchange Offer and held by it following consummation of the Registered Exchange Offer or (iv) any Holder (other than an
Exchanging Dealer) is not eligible to participate in the Registered Exchange Offer or, in the case of any Holder (other than an Exchanging Dealer) that participates in the Registered Exchange Offer, such Holder does not receive freely tradeable
Exchange Securities on the date of the exchange and any such Holder so requests, the Company shall take the following actions: 
 (a) The Company shall, at its cost, as promptly as practicable (but in no event more than 60 days after so required or requested pursuant to this Section 2) file with the Commission and thereafter
shall use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically upon filing) a registration statement (the “Shelf Registration Statement” and, together with the Exchange Offer Registration
Statement, a “Registration Statement”) on an appropriate form under the Securities Act relating to the offer and sale of the Transfer Restricted Securities (as defined in Section 6(d) hereof) by the Holders thereof from time to time
in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf Registration”), it being agreed that in the case the Company is filing a Shelf
Registration Statement due to (x) the occurrence of the events specified in clause (i) of this Section 2, the Company shall use its reasonable best efforts to have such Shelf Registration Statement declared effective on or prior to
the 270th day after the Issue Date or (y) the occurrence of the events specified in clause (ii), (iii) or (iv) of this Section 2, the Company shall use its reasonable best efforts to have such Shelf Registration Statement
declared effective on or prior to the 60th day after the date on which the Shelf Registration Statement is required to be filed; provided, however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it
covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder. 
 (b) The Company shall use its reasonable best efforts to keep the Shelf Registration Statement continuously effective in order to permit the prospectus included therein to be lawfully delivered by the
Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 3(j) below) from the Issue Date or such shorter period that will terminate when all the Securities covered by the Shelf
Registration Statement (i) have been sold pursuant thereto or (ii) are no longer restricted securities (as defined in Rule 144 under the Securities Act, or any successor rule thereof). The Company shall be deemed not to have used its
reasonable best efforts to keep the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby

  
 4 

 
not being able to offer and sell such Securities during that period, unless such action is required by applicable law. 

(c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration
Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the
Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein,
in light of the circumstances under which they were made, not misleading. 
 3. Registration Procedures. To the extent
applicable, in connection with any Shelf Registration contemplated by Section 2 hereof and any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 

(a) The Company shall (i) furnish to the Initial Purchasers, prior to the filing thereof with the Commission, a copy
of the Registration Statement and each amendment thereof and each supplement, if any, to the prospectus included therein and, in the event that an Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is
participating in the Registered Exchange Offer or the Shelf Registration Statement, the Company shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may
propose; (ii) in the case of a Registered Exchange Offer, include the information set forth in Annex A hereto on the cover, in Annex B hereto in the “Exchange Offer Procedures” section and the “Purpose of the Exchange Offer”
section and in Annex C hereto in the “Plan of Distribution” section of the prospectus forming a part of the Exchange Offer Registration Statement and include the information set forth in Annex D hereto in the Letter of Transmittal
delivered pursuant to the Registered Exchange Offer; (iii) in the case of a Registered Exchange Offer, if requested by an Initial Purchaser, include the information required by Items 507 or 508 of Regulation S-K under the Securities Act, as
applicable, in the prospectus forming a part of the Exchange Offer Registration Statement; (iv) in the case of a Registered Exchange Offer, include within the prospectus contained in the Exchange Offer Registration Statement a section
entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchasers, which shall contain a summary statement of the positions taken or policies made by the staff of the Commission with respect to the potential
“underwriter” status of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of Exchange Securities received by such broker-dealer in
the Registered Exchange Offer (a “Participating Broker-Dealer”), whether such positions or policies have been publicly disseminated by the staff of the Commission or such positions or policies, in the reasonable judgment of the Initial
Purchasers based upon advice of counsel (which may be in-house counsel), represent the prevailing views of the staff of the Commission; and (v) in the case of a Shelf Registration Statement, include in the prospectus included in the Shelf
Registration Statement (or, if permitted by Commission Rule 430B(b), in a prospectus supplement that becomes a part thereof pursuant to Commission Rule 430B(f)) that is delivered to any Holder pursuant to Section 3(d) and (f),
the names of the Holders, who propose to sell Securities pursuant to the Shelf Registration Statement, as selling security holders. 
 (b) The Company shall give written notice to the Initial Purchasers, the Holders and any Participating Broker-Dealer from whom the Company has received prior written notice that it will be a Participating
Broker-Dealer in the Registered Exchange Offer (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made): 

(i) when the Registration Statement or any amendment thereto has been filed with the Commission and when the Registration
Statement or any post-effective amendment thereto has become effective; 

  
 5 

 (ii) of any request by the Commission for amendments or supplements to the
Registration Statement or the prospectus included therein or for additional information; 
 (iii) of the issuance
by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose, of the issuance by the Commission of a notification of objection to the use of the form on which
the Registration Statement has been filed, and of the happening of any event that causes the Company to become an “ineligible issuer,” as defined in Commission Rule 405; 

(iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the
qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 
 (v) of the happening of any event that requires the Company to make changes in the Registration Statement or the prospectus in order that the Registration Statement or the prospectus do not contain an
untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading.

 (c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of
any order suspending the effectiveness of the Registration Statement. 
 (d) The Company shall furnish to each
Holder of Securities included within the coverage of any Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment or supplement thereto, including financial statements and schedules,
if any, included therein, and, if the Holder so requests in writing, all exhibits thereto (other than those, if any, incorporated by reference). The Company shall not, without the prior consent of the Initial Purchasers, make any offer relating to
the Securities that would constitute a “free writing prospectus,” as defined in Commission Rule 405. 
 (e) The Company shall deliver to each Exchanging Dealer and each Initial Purchaser, and to any other Holder who so requests in writing, without charge, at least one copy of the Exchange Offer Registration
Statement and any post-effective amendment thereto, including financial statements and schedules, if any, included therein, and, if an Initial Purchaser or any such Holder so requests, all exhibits thereto (other than those incorporated by
reference). 
 (f) The Company shall, during the period of effectiveness of the Shelf Registration Statement,
deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the Shelf Registration Statement and any amendment or
supplement thereto as such person may reasonably request in writing. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or any amendment or supplement thereto by each of the selling Holders in connection
with the offering and sale of the Securities covered by the prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement. 
 (g) The Company shall deliver to each Initial Purchaser, any Exchanging Dealer, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange
Offer, without charge, as many copies of the final prospectus included in the Exchange Offer Registration Statement and any amendment or supplement thereto as such persons may reasonably request. The Company consents, subject to the provisions of
this Agreement, to the use of the prospectus or any amendment or supplement thereto by the Initial Purchasers, if necessary, any Participating Broker-Dealer and such other persons required to deliver a prospectus following the Registered Exchange
Offer in connection with the offering and sale of the Exchange 

  
 6 

 
Securities covered by the prospectus, or any amendment or supplement thereto, included in such Exchange Offer Registration Statement. 

(h) Prior to any public offering of the Securities pursuant to a Shelf Registration Statement, the Company shall register
or qualify or cooperate with the Holders included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue sky” laws of such states of the
United States as any Holder reasonably requests in writing and do any and all other acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement;
provided, however, that the Company shall not be required to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified as of the date hereof
or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise subject as of the date hereof. 
 (i) The Company shall cooperate with the Holders to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any Registration Statement free of any
restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to such Registration Statement. 

(j) Upon the occurrence of any event contemplated by paragraphs (ii) through (v) of Section 3(b) above
during the period for which the Company is required to maintain an effective Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Registration Statement or a supplement to the related prospectus and
any other required document so that, as thereafter delivered to Holders or purchasers of Securities, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchasers, the Holders and any known Participating Broker-Dealer in accordance with paragraphs
(ii) through (v) of Section 3(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Initial Purchasers, the Holders and any such Participating Broker-Dealers shall suspend
use of such prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 2(b) above and the Exchange Offer Registration Statement provided for in Section 1 above shall each be extended by the
number of days from and including the date of the giving of such notice to and including the date when the Initial Purchasers, the Holders and any known Participating Broker-Dealer shall have received such amended or supplemented prospectus pursuant
to this Section 3(j). During the period during which the Company is required to maintain an effective Shelf Registration Statement pursuant to this Agreement, the Company will prior to the three-year expiration of that Shelf Registration
Statement file, and use its reasonable best efforts to cause to be declared effective (unless it becomes effective automatically upon filing) within a period that avoids any interruption in the ability of Holders of Securities covered by the
expiring Shelf Registration Statement to make registered dispositions, a new registration statement relating to the Securities, which shall be deemed the “Shelf Registration Statement” for purposes of this Agreement. 

(k) Not later than the effective date of the applicable Registration Statement, the Company will provide a CUSIP number
for the Initial Securities, the Exchange Securities or the Private Exchange Securities, as the case may be, and provide the applicable trustee with printed certificates for the Initial Securities, the Exchange Securities or the Private Exchange
Securities, as the case may be, in a form eligible for deposit with The Depository Trust Company. 
 (l) The
Company will comply in all material respects with all rules and regulations of the Commission to the extent and so long as they are applicable to the Registered Exchange Offer or the Shelf Registration, as the case may be, and, in the case of a
Shelf Registration Statement, will make generally available to its security holders (or otherwise provide in accordance with Section 

  
 7 

 
11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if
such period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement, which statement shall cover such 12-month period. 

(m) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, in a timely
manner, as required by the rules and regulations of the Commission and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the
Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 
 (n) The Company may require each Holder of Securities to be sold pursuant to the Shelf Registration Statement to furnish to the Company such information regarding the Holder and the distribution of the
Securities as the Company may from time to time reasonably require for inclusion in the Shelf Registration Statement, and the Company may exclude from such registration the Securities of any Holder that unreasonably fails to furnish such information
within a reasonable time after receiving such request. 
 (o) The Company shall enter into such customary
agreements (including, if requested, an underwriting agreement in customary form) and take all such other action, if any, as any Holder shall reasonably request in order to facilitate the disposition of the Securities pursuant to any Shelf
Registration. 
 (p) In the case of any Shelf Registration, the Company shall (i) make reasonably available
for inspection by the Holders, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders or any such underwriter all relevant financial and other
records, pertinent corporate documents and properties of the Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders or any such
underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the
Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchasers by you and on behalf of the other parties, by one counsel designated by and on behalf of such other
parties as described in Section 4 hereof. 
 (q) In the case of any Shelf Registration, the Company, if
requested by any Holder of Securities covered thereby, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Securities in customary form addressed to such Holders and the managing underwriters, if any, thereof
and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (it being agreed that the matters to be covered by such opinion shall include, without limitation, the due incorporation and good standing of the
Company; the qualification of the Company to transact business as foreign corporations; the due authorization, execution and delivery of the relevant agreement of the type referred to in Section 3(o) hereof; the due authorization, execution,
authentication and issuance, and the validity and enforceability, of the applicable Securities; the absence of material legal or governmental proceedings involving the Company; the absence of governmental approvals required to be obtained in
connection with the Shelf Registration Statement, the offering and sale of the applicable Securities, or any agreement of the type referred to in Section 3(o) hereof; the compliance in all material respects, as to form of such Shelf
Registration Statement and any documents incorporated by reference therein and of the Indenture with the requirements of the Securities Act and the Trust Indenture Act, respectively; and (A) as of the date of the opinion and as of the effective
date of the Shelf Registration Statement or most recent post-effective amendment thereto, as the case may be, the absence, to the knowledge of such counsel, from such Shelf Registration Statement and the prospectus included

  
 8 

 
therein, as then amended or supplemented, and from any documents incorporated by reference therein and (B) as of an applicable time identified by such Holders or managing underwriters, the
absence, to the knowledge of such counsel, from such prospectus taken together with any other documents identified by such Holders or managing underwriters, in the case of (A) and (B), of an untrue statement of a material fact or the
omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any such documents, in the light of the circumstances existing at the time that such documents were
filed with the Commission under the Exchange Act); (ii) its officers to execute and deliver all customary documents and certificates and updates thereof reasonably requested by any underwriters of the applicable Securities and (iii) its
independent public accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Shelf Registration Statement to provide to the selling Holders of the applicable Securities and
any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated,
and only if permitted, by Statement of Auditing Standards No. 72. 
 (r) In the case of the Registered
Exchange Offer, if requested by an Initial Purchaser or any known Participating Broker-Dealer, the Company shall cause (i) its counsel to deliver to the Initial Purchaser or such Participating Broker-Dealer a signed opinion in the form set
forth in Section 7(e) of the Purchase Agreement with such changes as are customary in connection with the preparation of a Registration Statement and (ii) its independent public accountants and the independent public accountants with
respect to any other entity for which financial information is provided in the Registration Statement to deliver to such Initial Purchaser or such Participating Broker-Dealer a comfort letter, in customary form, meeting the requirements as to the
substance thereof as set forth in Section 7(a) and (b) of the Purchase Agreement, with appropriate date changes. 
 (s) If a Registered Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Initial Securities by Holders to the Company (or to such other Person as directed by the Company) in
exchange for the Exchange Securities or the Private Exchange Securities, as the case may be, the Company shall mark, or cause to be marked, on the Initial Securities so exchanged that such Initial Securities are being canceled in exchange for the
Exchange Securities or the Private Exchange Securities, as the case may be; in no event shall the Initial Securities be marked as paid or otherwise satisfied. 
 (t) The Company will use its reasonable best efforts to (a) if the Initial Securities have been rated prior to the initial sale of such Initial Securities, confirm such ratings will apply to the
Securities covered by a Registration Statement, or (b) if the Initial Securities were not previously rated, cause the Securities covered by a Registration Statement to be rated with the appropriate rating agencies, if so requested by Holders of
a majority in aggregate principal amount of Securities covered by such Registration Statement, or by the managing underwriters, if any. 
 (u) In the event that any broker-dealer registered under the Exchange Act shall underwrite any Securities or participate as a member of an underwriting syndicate or selling group or “assist in the
distribution” (within the meaning of the Conduct Rules (the “Rules”) of the Financial Industry Regulatory Authority, Inc. (“FINRA”)) thereof, whether as a Holder of such Securities or as an underwriter, a placement or sales
agent or a broker or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in complying with the requirements of such Rules, including, without limitation, by (i) if such Rules, including NASD Rule 2720, shall so
require, engaging a “qualified independent underwriter” (as defined in Rule 2720) to participate in the preparation of the Registration Statement relating to such Securities, to exercise usual standards of due diligence in respect thereto
and, if any portion of the offering contemplated by such Registration Statement is an underwritten offering or is made through a placement or sales agent, to recommend the yield of such Securities, (ii) indemnifying any such qualified
independent underwriter to the extent of the indemnification of underwriters provided in Section 5 hereof and 

  
 9 

 
(iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 

(v) The Company shall use its reasonable best efforts to take all other steps necessary to effect the registration of the
Securities covered by a Registration Statement contemplated hereby. 
 4. Registration Expenses. The Company shall bear
all fees and expenses incurred by it in connection with the performance of its obligations under Sections 1 through 3 hereof and shall also pay the reasonable fees and expenses, if any, of Cravath, Swaine & Moore LLP, counsel for the
Initial Purchasers, incurred in connection with the Registered Exchange Offer, whether or not the Registered Exchange Offer is filed or becomes effective, and, in the event a Shelf Registration Statement is required to be filed hereunder, shall bear
or reimburse the Holders of the Securities covered thereby for the reasonable fees and disbursements of one firm of counsel designated by the Holders of a majority in principal amount of the Initial Securities covered thereby to act as counsel for
the Holders of the Initial Securities in connection therewith. 
 5. Indemnification. (a) The Company agrees to
indemnify and hold harmless each Holder, any Participating Broker-Dealer and each person, if any, who controls such Holder or such Participating Broker-Dealer within the meaning of the Securities Act or the Exchange Act (each Holder, any
Participating Broker-Dealer and such controlling persons are referred to collectively as the “Indemnified Parties” and individually as an “Indemnified Party”) from and against any losses, claims, damages or liabilities, joint or
several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities
Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or
prospectus or in any amendment or supplement thereto or in any preliminary prospectus or “issuer free writing prospectus,” as defined in Commission Rule 433 (“Issuer FWP”), relating to a Shelf Registration, or arise out of,
or are based upon, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or
other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the
extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in a Registration Statement or prospectus or in any amendment or supplement
thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically
for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of any Holder or Participating Broker-Dealer from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus
relating to such Securities was required to be delivered (including through satisfaction of the conditions of Commission Rule 172) by such Holder or Participating Broker-Dealer under the Securities Act in connection with such purchase and any
such loss, claim, damage or liability of such Holder or Participating Broker-Dealer results from the fact that there was not conveyed to such person, at or prior to the time of the sale of such Securities to such person, an amended or supplemented
prospectus or, if permitted by Section 3(d), an Issuer FWP correcting such untrue statement or omission or alleged untrue statement or omission if the Company had previously furnished copies thereof to such Holder or Participating
Broker-Dealer; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The Company shall also indemnify underwriters, their officers and directors
and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Holders if requested by such Holders. 

  
 10 

 (b) Each Holder, severally and not jointly, will indemnify and hold harmless
the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any
such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a
material fact contained in a Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus or Issuer FWP relating to a Shelf Registration, or arise out of or are based upon the omission or alleged
omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in
conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall
reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This
indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons. 
 (c) Promptly after receipt by an Indemnified Party under this Section 5 of notice of the commencement of any action or proceeding (including a governmental investigation), such Indemnified Party
will, if a claim in respect thereof is to be made against the indemnifying party under this Section 5, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve the
indemnifying party from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure;
provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an Indemnified Party otherwise than under subsection (a) or (b) above. In case any such action is
brought against any Indemnified Party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party
similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such Indemnified Party of its election so to assume the defense thereof the indemnifying party will not be liable to such Indemnified Party under this Section 5 for any legal or other expenses, other than reasonable costs
of investigation, subsequently incurred by such Indemnified Party in connection with the defense thereof. No indemnifying party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending or threatened
action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party unless such settlement (i) includes an unconditional release of such Indemnified Party from
all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party. 

(d) If the indemnification provided for in this Section 5 is unavailable or insufficient to hold harmless an
Indemnified Party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect
thereof) referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the Indemnified Party on the other from
the exchange of the Securities, pursuant to the Registered Exchange Offer, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the Indemnified Party on the 

  
 11 

 
other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable
considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or such Holder or such other Indemnified Party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such
statement or omission. The amount paid by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably
incurred by such Indemnified Party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 5(d), the Holders shall not be required to
contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Securities pursuant to a Registration Statement exceeds the amount of damages which such Holders have otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such Indemnified Party within the meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as such Indemnified Party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company. 

(e) The agreements contained in this Section 5 shall survive the sale of the Securities pursuant to a Registration
Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any Indemnified Party. 

6. Additional Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”) with
respect to the Transfer Restricted Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (v) below a “Registration Default”: 

(i) on or prior to June 20, 2011, the Exchange Offer Registration Statement has not been filed with the Commission;

 (ii) the Company is required to file a Shelf Registration Statement pursuant to the terms of Section 2(a)
above, the Shelf Registration Statement has not been filed with the Commission on or prior to the 60th day after the date on which the obligation to file such Shelf Registration Statement arises, determined in accordance with the terms of
Section 2(a) above; 
 (iii) on or prior to September 19, 2011, neither the Registered Exchange Offer
nor, if required in lieu thereof, the Shelf Registration Statement, is declared effective by the Commission; 

(iv) the Exchange Offer is not consummated on or before the 40th day after the Exchange Offer Registration Statement is
declared effective or, if obligated to file a Shelf Registration Statement pursuant to the terms of Section 2 above, the Shelf Registration Statement is not declared effective on or prior to the 60th day after the date of the filing of the
Shelf Registration Statement; or 
 (v) after either the Exchange Offer Registration Statement or the Shelf
Registration Statement is declared (or becomes automatically) effective (A) such Registration Statement thereafter ceases to be effective; or (B) such Registration Statement or the related prospectus ceases to be usable (except as
permitted in paragraph 

  
 12 

 
(b) immediately below) in connection with resales of Transfer Restricted Securities during the periods specified herein because either (1) any event occurs as a result of which the related
prospectus forming part of such Registration Statement would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not
misleading, (2) it shall be necessary to amend such Registration Statement or supplement the related prospectus, to comply with the Securities Act or the Exchange Act or the respective rules thereunder, or (3) such Registration Statement
is a Shelf Registration Statement that has expired, if required, before a replacement Shelf Registration Statement has become effective. 

Additional Interest shall accrue on the Transfer Restricted Securities over and above the interest set forth in the title of the Securities from and
including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of $0.05 per week per $1,000 principal amount of the Transfer Restricted Securities
for the first 90-day period immediately following the occurrence of a Registration Default, and such rate will increase by an additional $0.05 per week per $1,000 principal amount of the Transfer Restricted Securities with respect to each subsequent
90-day period until all Registration Defaults have been cured, up to a maximum additional interest rate of 1.0% per annum. 
 (b) A Registration Default referred to in Section 6(a)(v)(B) hereof shall be deemed not to have occurred and be continuing in relation to a Shelf Registration Statement or the related prospectus if
(i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to such Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such
post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events with respect to the Company that would need to be described in such Shelf Registration
Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related prospectus to describe such material events;
provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until
such Registration Default is cured. 
 (c) Any amounts of Additional Interest due pursuant to clause (i), (ii),
(iii), (iv) or (v) of Section 6(a) above will be payable in cash on the regular interest payment dates with respect to the Transfer Restricted Securities. The amount of Additional Interest will be determined on the basis of the number
of days that Additional Interest is payable hereunder and on the basis of a 360-day year comprised of twelve 30-day months. 
 (d) “Transfer Restricted Securities” means each Security until (i) the date on which such Transfer Restricted Security has been exchanged by a person other than a broker-dealer for a freely
transferable Exchange Security in the Registered Exchange Offer, (ii) following the exchange by a broker-dealer in the Registered Exchange Offer of an Initial Security for an Exchange Security, the date on which such Exchange Security is sold
to a purchaser who receives from such broker-dealer on or prior to the date of such sale a copy of the prospectus contained in the Exchange Offer Registration Statement, (iii) the date on which such Transfer Restricted Security has been
effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement. 
 7.
Rules 144 and 144A. So long as it is required to do so by the Indenture, the Company shall use its reasonable best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner
and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder of Initial Securities, make publicly available other information so long as necessary to permit sales of their securities pursuant to
Rules 144 and 144A. The Company covenants that it will take such further action as any Holder of Initial Securities may reasonably request, all to the 

  
 13 

 
extent required from time to time to enable such Holder to sell Initial Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144
and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Initial Securities identified to the Company by the Initial Purchasers upon written request. Upon the
written request of any Holder of Initial Securities, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its securities pursuant to the Exchange Act. 
 8. Underwritten
Registrations. If any of the Transfer Restricted Securities covered by any Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering
will be selected by the Holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering. 
 No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any
underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements. 
 9. Miscellaneous. 

(a) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Securities affected by such amendment, modification, supplement,
waiver or consents.

principal amount of Securities is required hereunder, Securities held by the Company or its affiliates (other than subsequent Holders of Securities if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such

 ANNEX A 
 Each broker-dealer that receives Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange
Securities. The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This Prospectus, as it
may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities. The Company has agreed that, for a period of 180 days after the Expiration Date (as defined herein), it will make this Prospectus available to any broker-dealer for use in connection
with any such resale. See “Plan of Distribution.” 

 ANNEX B 
 Each broker-dealer that receives Exchange Securities for its own account in exchange for Initial Securities, where such Initial Securities were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such Exchange Securities. See “Plan of Distribution.” 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each broker-dealer that receives
Exchange Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a Prospectus in connection with any resale of such Exchange Securities. This Prospectus, as it may be amended or supplemented from time to
time, may be used by a broker-dealer in connection with resales of Exchange Securities received in exchange for Initial Securities where such Initial Securities were acquired as a result of market-making activities or other trading activities. The
Company has agreed that, for a period of 180 days after the Expiration Date, it will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until
[        ], 20[    ], all dealers effecting transactions in the Exchange Securities may be required to deliver a prospectus.(1) 
 The Company will not receive any proceeds from any sale of Exchange Securities by broker-dealers. Exchange Securities received by broker-dealers for their own account pursuant to the Exchange Offer may be
sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the Exchange Securities or a combination of such methods of resale, at market prices prevailing at the
time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions
from any such broker-dealer or the purchasers of any such Exchange Securities. Any broker-dealer that resells Exchange Securities that were received by it for its own account pursuant to the Exchange Offer and any broker or dealer that participates
in a distribution of such Exchange Securities may be deemed to be an “underwriter” within the meaning of the Securities Act and any profit on any such resale of Exchange Securities and any commission or concessions received by any such
persons may be deemed to be underwriting compensation under the Securities Act. The Letter of Transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an
“underwriter” within the meaning of the Securities Act. 
 For a period of 180 days after the Expiration Date the
Company will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any broker-dealer that requests such documents in the Letter of Transmittal. The Company has agreed to pay all of its expenses
incident to the Exchange Offer and the reasonable expenses of one counsel for the Holders other than commissions or concessions of any brokers or dealers and will indemnify the Holders (including any broker-dealers) against certain liabilities,
including liabilities under the Securities Act. 
  
  

	(1)	 In addition, the legend required by Item 502(e) of Regulation S-K will appear on the back cover page of the Exchange Offer prospectus.

 ANNEX D 
  ̈            CHECK HERE IF YOU ARE A BROKER-DEALER AND WISH TO RECEIVE 10 ADDITIONAL COPIES OF
THE PROSPECTUS AND 10 COPIES OF ANY AMENDMENTS OR SUPPLEMENTS THERETO.

 If the undersigned is not a broker-dealer, the undersigned represents that it is not engaged in, and does not intend
to engage in, a distribution of Exchange Securities. If the undersigned is a broker-dealer that will receive Exchange Securities for its own account in exchange for Initial Securities that were acquired as a result of market-making activities or
other trading activities, it acknowledges that it will deliver a prospectus in connection with any resale of such Exchange Securities; however, by so acknowledging and by delivering a prospectus, the undersigned will not be deemed to admit that it
is an “underwriter” within the meaning of the Securities Act.
