REGISTRATION RIGHTS AGREEMENT 

October 6, 2010 
 Credit
Suisse Securities (USA) LLC 
 Eleven Madison Avenue 

New York, New York 10010-3629 

Dear Sirs: 
 Rotech Healthcare
Inc., a Delaware corporation (the “Issuer”), proposes to issue and sell to Credit Suisse Securities (USA) LLC (the “Initial Purchaser”), upon the terms set forth in a purchase agreement, dated September 29, 2010 (the
“Purchase Agreement”), $230,000,000 aggregate principal amount of its 10.75% Senior Secured Notes due 2015 (the “Initial Securities”) to be unconditionally guaranteed on a senior secured basis by each of the subsidiaries of the
Issuer listed on Schedule A hereto (the “Guarantors” and, together with the Issuer, the “Company”). The Initial Securities will be issued pursuant to an indenture, dated as of the date hereof (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 Purchaser to enter into the Purchase Agreement, the Company agrees with the Initial Purchaser, for
the benefit of the holders of the Initial Securities (including the Initial Purchaser), the Exchange Securities (as defined below) and the Private Exchange Securities (as defined below) (collectively, the “Holders”), as follows:

 1. Registered Exchange Offer. The Company shall, at its own cost, prepare and, not later than 180 days (or
if the 180th day is not a business day, the first business day thereafter) (such 180th day or the first business day thereafter being an “Exchange Offer Filing Deadline”) after the date of original issue of the Initial Securities (the
“Issue Date”), file with the Securities and Exchange Commission (the “Commission”) a registration statement (the “Exchange Offer Registration Statement”) 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 Initial 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, a like aggregate principal amount of debt securities (the “Exchange Securities”) of the Company 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) and that would be registered under
the Securities Act. The Company shall use its reasonable best efforts to (i) 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 (such 270th day (or the first business day thereafter) being an 







 
“Effectiveness Deadline”) and (ii) keep the Exchange Offer Registration Statement effective for not less than 20 business 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 commences the Registered Exchange Offer, the Company (i) will be entitled to close the Registered Exchange Offer 20
business 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 and (ii) shall consummate the Registered
Exchange Offer no later than 40 days (or longer if required by applicable law) after the date on which the Exchange Offer Registration Statement is declared effective (or if the 40th day is not a business day, the first business day thereafter)
(such day being the “Consummation Deadline”) by the Commission. 
 Following the declaration of the effectiveness of
the Exchange Offer Registration Statement, the Company shall as soon as practicable commence the Registered Exchange Offer, it being the objective of such Registered Exchange Offer to enable each Holder of Initial Securities 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 that 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 Purchaser elects to sell Exchange Securities acquired in exchange for Initial Securities constituting any portion of an unsold allotment, it is 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 Purchaser,
such period shall be the lesser of 90 days and the date on which all Exchanging Dealers and the Initial Purchaser 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 90 days after the consummation of the
Registered Exchange Offer. 
  

 2 








 If, upon consummation of the Registered Exchange Offer, the 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 the Initial Purchaser upon the written
request of the Initial Purchaser, in exchange (the “Private Exchange”) for the Initial Securities held by the Initial Purchaser, a like principal amount of debt securities of the Company issued under the Indenture and identical in all
material respects (including the existence of 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 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 20 business 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 Initial 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 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 Initial 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 will provide that the Exchange Securities will not be subject to the transfer restrictions set forth in the Indenture and
that all the Securities will vote and consent together on all matters as one class and that none of the Securities will have the right to vote or consent as a class separate from one another on any matter. 

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 date of original issue of the Initial
Securities. 
  

 3 








 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 Initial 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 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 270 days of the Issue Date, (iii) the 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, the Company shall take the following actions: 

(a) The Company shall, at its cost, as promptly as practicable (but in no event more than 30 days after so required
or requested pursuant to this Section 2) (such 30th day being a “Shelf Registration Statement Filing Deadline,” together with the Exchange Offer Filing Deadline, each, a “Filing Deadline”) file with the Commission and
thereafter (x) in the case of Section 2(i) above, use its reasonable best efforts to cause to be declared effective on or prior to the 270th day after the Issue Date or (y) in the case of Section 2(ii), (iii) or
(iv) above, use its reasonable best efforts to cause be declared effective (unless it becomes effective automatically upon filing) on or prior to 90th day after the Shelf Registration Statement Filing Deadline (such 270th or 90th day,
respectively, being an “Effectiveness Deadline”) a shelf 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 by the Holders thereof from time to time in accordance 

 

 4 








 
with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act (hereinafter, the “Shelf Registration”); provided,
however, that no Holder (other than the 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 have been sold pursuant thereto (the “Shelf Registration Period”). 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 covered thereby not being able to offer and
sell such Securities during that period, unless such action is required by applicable law, as reasonably determined by the Company in its good faith judgment. 

(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 the light of the circumstances under which they were made, not misleading. 
 3. Registration
Procedures. In connection with any Shelf Registration contemplated by Section 2 hereof and, to the extent applicable, any Registered Exchange Offer contemplated by Section 1 hereof, the following provisions shall apply: 

(a) The Company shall (i) furnish to the Initial Purchaser, 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 the 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 reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as the Initial
Purchaser reasonably may propose; (ii) 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) if requested by the 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) include within the prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” reasonably acceptable to the Initial Purchaser, 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 

 

 5 








 
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
Purchaser 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 Purchaser, 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; 

(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 the 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 the 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, and, if the Holder so requests in writing, all exhibits thereto (including
those, if any, incorporated by reference). The Company shall not, without the prior consent of the Initial Purchaser, make any offer relating to the Securities that would constitute a “free writing prospectus,” as defined in Commission
Rule 405. 
  

 6 








 (e) The Company shall deliver to each Exchanging Dealer and the Initial
Purchaser, and to any other Holder who so requests, without charge, at least one copy of the Exchange Offer Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if the Initial Purchaser
or any such Holder requests, all exhibits thereto (including those incorporated by reference). 
 (f) The
Company shall, during the Shelf Registration Period, 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. 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 the 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 Purchaser, 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 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 any
Registration Statement, the Company shall register or qualify or cooperate with the Holders of Securities 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 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 (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any
action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 

(i) Unless the Securities are in book-entry form, 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 
  

 7 








 
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 the light of the circumstances under which they were made, not misleading. If the Company notifies the Initial Purchaser, 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 Purchaser, 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 Purchaser, 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 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 and will make generally available to its security holders (or otherwise provide in accordance with Section 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 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. 

 

 8 








 (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 of Securities to be sold pursuant to any Shelf Registration Statement 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 of Securities to be sold pursuant to any Shelf Registration Statement, 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 (A) by the Initial Purchaser on behalf of itself and (B) 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 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 the due incorporation and good standing of the Company and its subsidiaries; the qualification of the Company and its subsidiaries to

and enforceability, of the applicable Securities; the absence of material legal or governmental proceedings involving the Company and its subsidiaries; 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 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 from such Shelf Registration Statement and the prospectus included 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 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 incorporated 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 requested by any underwriters
of the applicable Securities and (iii) its independent registered public accounting firm and the independent registered public accounting firm with respect to any other entity for which financial information is provided in the Shelf

(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.

including by (i) if such Rules, including 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

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. 

 

 10 








 4. Registration Expenses. The Company shall bear all fees and expenses incurred

or reimburse the Holders of the Securities covered thereby for an amount not to exceed $25,000 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 Issuer and the Guarantors, jointly and severally, agree 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”) 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 Issuer and the Guarantors may otherwise have to such Indemnified Party. The Issuer and the Guarantors 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. 

(b) Each Holder, severally and not jointly, will indemnify and hold harmless the Issuer, the Guarantors and each person, if any, who
controls the Issuer or the Guarantors, as the case may be, within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or 

 

 11 








 
liabilities or any actions in respect thereof, to which the Issuer, the Guarantors 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 Issuer or the Guarantors, as the case may be, for any legal or other expenses reasonably
incurred by the Issuer, the Guarantors 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 that
such Holder may otherwise have to the Issuer, the Guarantors or any of their 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; and provided further 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 other in connection with the statements or omissions that resulted in such losses,

  

 12 








 
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
subsection (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
Issuer or the Guarantors within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Issuer or the Guarantors, as the case may be. 

(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 (iv) below a “Registration Default”): 

(i) any Registration Statement required by this Agreement is not filed with the Commission on or prior to the
applicable Filing Deadline; 
 (ii) any Registration Statement required by this Agreement is not declared
effective by the Commission on or prior to the applicable Effectiveness Deadline; 
 (iii) if after the
Exchange Offer Registration Statement becomes effective, the Registered Exchange Offer is not consummated on or prior to the Consummation Deadline; or 

(iv) if 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 (b)) 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 before a replacement Shelf
Registration Statement has become effective. 
  

 13 








 Additional Interest shall accrue on the Transfer Restricted Securities over and above the interest set forth
in the title of the Transfer Restricted 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 0.25% per annum
(the “Additional Interest Rate”) for the first 90-day period immediately following the occurrence of such Registration Default. The Additional Interest Rate shall increase by an additional 0.25% per annum 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; provided that the Company shall in no event be required to pay Additional Interest for more than one
Registration Default at any given time. 
 (b) A Registration Default referred to in Section 6(a)(iv)(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 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 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 by multiplying the applicable Additional Interest Rate by the principal amount of the Transfer Restricted Securities and further
multiplied by a fraction, the numerator of which is the number of days such Additional Interest Rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is
360. 
 (d) “Transfer Restricted Securities” means each Initial Security until (i) the date on which such
Initial 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 Note, the date on which such Exchange Note 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 Initial Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (iv) the date on which such Initial Security is sold
pursuant to Rule 144. 
 7. Rules 144 and 144A. 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 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 Purchaser upon request. Upon the 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. 
  

 14 








 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 (“Managing Underwriters”) 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) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Sections 1
and 2 hereof may result in material irreparable injury to the Initial Purchaser or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any
such failure, the Initial Purchaser or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations under Sections 1 and 2 hereof. The Company further agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate. The Initial Purchaser and the Holders acknowledge and agree that the Additional Interest provided by Section 6 of this Agreement shall be the exclusive monetary remedy available to
Holders for any Registration Default. 
 (b) Third-Party Beneficiaries. The Holders shall be third-party beneficiaries to
the agreements made hereunder between the Company, on the one hand, and the Initial Purchaser, on the other hand, and shall have the right to enforce such agreements directly to the extent they may deem such enforcement necessary or advisable to
protect their rights or the rights of Holders hereunder. 
 (c) 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 aggregate principal amount of
the Securities affected by such amendment, modification, supplement, waiver or consents. Without the consent of the Holder of each Security, however, no modification may change the provisions relating to the payment of Additional Interest.

 (d) Notices. All notices and other communications provided for or permitted hereunder shall be made in
writing by hand delivery, first-class mail, facsimile transmission or air courier which guarantees overnight delivery:

(k) Securities Held by the Company. Whenever the consent or approval of Holders of a specified percentage of principal
amount of Securities is required hereunder, Securities held by the Company or its affiliates (other than subsequent Holders if such subsequent Holders are deemed to be affiliates solely by reason of their holdings of such Securities) shall not be
counted in determining whether such consent or approval was given by the Holders of such required percentage. 
 If the
foregoing is in accordance with your understanding of our agreement, please sign and return to the Issuer a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Initial Purchaser, the

 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 90 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.” 
  

 20 








 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 90 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             , 201  , 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 90 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 expenses incident to the Exchange Offer (including the expenses of one counsel for the Holders of the
Securities) other than commissions or concessions of any brokers or dealers and will indemnify the Holders of the Securities (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act. 

 
  

	(

)	 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. 
  

			
	Name:	 	  

	Address:	 	  

		 	  



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.
