 REGISTRATION RIGHTS AGREEMENT 

This Registration Rights Agreement (this “Agreement”) is dated as of January 28, 2011, among GREAT LAKES
DREDGE & DOCK CORPORATION, a Delaware Corporation (the “Company”), the guarantors listed on the signature pages hereto, (the “Guarantors”) and DEUTSCHE BANK SECURITIES INC. and MERRILL LYNCH, PIERCE,

The Company and the Guarantors are collectively referred to as the “Issuers.” 
 This Agreement is entered into
in connection with the Purchase Agreement, dated as of January 25, 2011, between the Issuers and the Representatives on behalf of the Initial Purchasers (the “Purchase Agreement”), which provides for, among other things, the
sale by the Company to the Initial Purchasers of $250,000,000 aggregate principal amount of the Company’s 7.375% Senior Notes Due 2019 (the “Notes”). The Notes are issued under an indenture, dated as of January 28, 2011
(as amended or supplemented from time to time, the “Indenture”), among the Issuers and Wells Fargo Bank, National Association, as trustee (the “Trustee”). Pursuant to the Purchase Agreement and the Indenture, the
Guarantors are required to unconditionally guarantee (collectively, the “Guarantees”) on a senior basis the Company’s obligations under the Notes and the Indenture. The Notes and the Guarantees are collectively referred to as
the “Securities.” In order to induce the Initial Purchasers to enter into the Purchase Agreement, the Issuers have agreed to provide the registration rights set forth in this Agreement for the benefit of the Initial Purchasers and,
except as otherwise set forth herein, any subsequent holder or holders of the Notes. The execution and delivery of this Agreement is a condition to the Initial Purchasers’ obligation to purchase the Notes under the Purchase Agreement.

	 	2.	Exchange Offer 

 (a)
Unless the Exchange Offer would not be permitted by applicable law or any applicable interpretation of the staff of the SEC, the Company shall use its commercially reasonable efforts to file with the SEC a Registration Statement (the
“Exchange Offer Registration Statement”) on an appropriate registration form with respect to a registered offer (the “Exchange Offer”) to exchange any and all of the Registrable Securities for a like aggregate
principal amount of debt securities of the Company (the “Exchange Notes”), guaranteed, to the extent applicable, on an unsecured senior basis by the Guarantors (the “New Guarantees” and, together with the Exchange
Notes, the “Exchange Securities”), that are identical in all material respects to the Notes, as applicable, except that (i) the Exchange Notes shall contain no restrictive legend thereon, (ii) interest thereon shall accrue
from the last date on which interest was paid on such Notes or, if no such interest has been paid, from the Issue Date and (iii) which are entitled to the benefits of the Indenture or a trust indenture which is identical in all material
respects to the Indenture (other than such changes to the Indenture or any such identical trust indenture as are necessary to comply with the TIA) and which, in either case, has been qualified under the TIA. The Exchange Offer shall comply with all
applicable tender offer rules and regulations under the Exchange Act and other applicable laws. The Company shall use its commercially reasonable efforts to (x) prepare and file with the SEC the Exchange Offer Registration Statement with
respect to the Exchange Offer; (y) keep the Exchange Offer open for at least 30 Business Days (or longer if required by applicable law) after the date that notice of the Exchange Offer is mailed to Holders; and (z) consummate the Exchange
Offer on or prior to the 5th Business Day following the expiration of the Exchange Offer. 

  
 -6-









 Each Holder (including, without limitation, each Participating Broker-Dealer) that
participates in the Exchange Offer, as a condition to participation in the Exchange Offer, will be required to represent to the Company in writing (which may be contained in the applicable letter of transmittal) that: (i) any Exchange
Securities acquired in exchange for Registrable Securities tendered are being acquired in the ordinary course of business of the Person receiving such Exchange Securities, whether or not such recipient is such Holder itself; (ii) at the time of
the commencement or consummation of the Exchange Offer neither such Holder nor, to the actual knowledge of such Holder, any other Person receiving Exchange Securities from such Holder has an arrangement or understanding with any Person to
participate in the distribution (within the meaning of the Securities Act) of the Exchange Securities in violation of the provisions of the Securities Act; (iii) neither the Holder nor, to the actual knowledge of such Holder, any other Person
receiving Exchange Securities from such Holder is an “affiliate” (as defined in Rule 405) of the Company or, if it is an affiliate of the Company, it will comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable and will provide information to be included in the Shelf Registration Statement in accordance with Section 5 hereof in order to have their Securities included in the Shelf Registration Statement and
benefit from the provisions regarding Additional Interest in Section 4 hereof; (iv) if such Holder is not a broker-dealer, neither such Holder nor, to the actual knowledge of such Holder, any other Person receiving Exchange Securities from
such Holder is engaging in or intends to engage in a distribution of the Exchange Securities; and (v) if such Holder is a Participating Broker-Dealer, such Holder has acquired the Registrable Securities for its own account in exchange for
Securities that were acquired as a result of market-making activities or other trading activities and that it will comply with the applicable provisions of the Securities Act (including, but not limited to, the prospectus delivery requirements
thereunder). 
 Upon consummation of the Exchange Offer in accordance with this Section 2, the provisions of this Agreement
shall continue to apply, mutatis mutandis, solely with respect to Registrable Securities that are Private Exchange Notes (and the related Guarantees), Exchange Securities as to which Section 2(c)(iv) is applicable and Exchange
Securities held by Participating Broker-Dealers, and the Company shall have no further obligation to register Registrable Securities (other than Private Exchange Notes (and the related Guarantees) and Exchange Securities as to which
clause 2(c)(iv) hereof applies) pursuant to Section 3 hereof. 
 No securities other than the Exchange Securities and
the Notes (and the related guarantees) shall be included in the Exchange Offer Registration Statement. 
 (b) The Company shall
include within the Prospectus contained in the Exchange Offer Registration Statement a section entitled “Plan of Distribution,” which shall contain a summary statement of the positions taken or policies made by the staff of the SEC with
respect to the potential “underwriter” status of any broker-dealer that is the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act) of Exchange Notes received by such broker-dealer in the Exchange Offer (a
“Participating Broker-Dealer”), whether such positions or policies have been publicly disseminated by the staff of the SEC or such positions or policies represent the prevailing views of the staff of the SEC. Such “Plan of
Distribution” section shall also expressly permit, to the extent permitted by applicable policies and regulations of the SEC, the use of the Prospectus by all Participating Broker-Dealers, and include a statement describing the means by which
Participating Broker-Dealers may resell the Exchange Securities in compliance with the Securities Act. 
 The Company shall use
its commercially reasonable 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 is necessary to comply with applicable law in connection with any resale of the Exchange Securities; provided, however, that such period shall not be
required to exceed 90 days, or such longer period if extended pursuant to the last paragraph of Section 5 hereof (the “Applicable Period”). 

  
 -7-









 If, prior to consummation of the Exchange Offer, the Initial Purchasers hold any Notes
acquired by them that have the status of an unsold allotment in the initial distribution, the Company, upon the request of the Initial Purchasers, shall simultaneously with the delivery of the Exchange Notes issue and deliver to the Initial
Purchasers, in exchange (the “Private Exchange”) for such Notes held by any such Holder, a like principal amount of notes (the “Private Exchange Notes”) of the Company, guaranteed by the Guarantors, that are
identical in all material respects to the Exchange Notes except for the placement of a restrictive legend on such Private Exchange Notes. The Private Exchange Notes shall be issued pursuant to the same indenture as the Exchange Notes and bear the
same CUSIP number as the Exchange Notes if permitted by the CUSIP Service Bureau. 
 In connection with the Exchange Offer, the
Company shall: 
 (1) mail, or cause to be mailed, to each Holder of record entitled to participate in the
Exchange Offer a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; 

(2) use their respective commercially reasonable efforts to keep the Exchange Offer open for not less than 30 Business
Days from the date that notice of the Exchange Offer is mailed to Holders (or longer if required by applicable law); 
 (3) utilize the services of a depositary for the Exchange Offer with an address in the Borough of Manhattan, The City of New York or in Wilmington, Delaware; 

(4) permit Holders to withdraw tendered Notes at any time prior to the close of business, New York time, on the last
Business Day on which the Exchange Offer remains open; and 
 (5) otherwise comply in all material respects with
all laws, rules and regulations applicable to the Exchange Offer. 
 As soon as practicable after the close of
the Exchange Offer and any Private Exchange, the Company shall: 
 (1) accept for exchange all Registrable
Securities validly tendered and not validly withdrawn pursuant to the Exchange Offer and any Private Exchange; 

(2) deliver to the Trustee for cancellation all Registrable Securities so accepted for exchange; and 

(3) cause the Trustee to authenticate and deliver promptly to each Holder of Notes, Exchange Notes or Private Exchange
Notes, as the case may be, equal in principal amount to the Notes of such Holder so accepted for exchange; provided that, in the case of any Notes held in global form by a depositary, authentication and delivery to such depositary of one or
more replacement Notes in global form in an equivalent principal amount thereto for the account of such Holders in accordance with the Indenture shall satisfy such authentication and delivery requirement. 

  
 -8-









 The Exchange Offer and the Private Exchange shall not be subject to any conditions, other
than that (i) the Exchange Offer or Private Exchange, as the case may be, does not violate applicable law or any applicable interpretation of the staff of the SEC; (ii) no action or proceeding shall have been instituted or threatened in
any court or by any governmental agency which might materially impair the ability of the Company to proceed with the Exchange Offer or the Private Exchange, and no material adverse development shall have occurred in any existing action or proceeding
with respect to the Company; and (iii) all governmental approvals shall have been obtained, which approvals the Company deem necessary for the consummation of the Exchange Offer or Private Exchange. 

The Exchange Securities and the Private Exchange Notes (and related guarantees) shall be issued under (i) the Indenture or
(ii) an indenture identical in all material respects to the Indenture and which, in either case, has been qualified under the TIA or is exempt from such qualification and shall provide that the Exchange Securities shall not be subject to the
transfer restrictions set forth in the Indenture. The Indenture or such indenture shall provide that the Exchange Notes, the Private Exchange Notes and the Notes shall vote and consent together on all matters as one class and that none of the
Exchange Notes, the Private Exchange Notes or the Notes will have the right to vote or consent as a separate class on any matter. 
 (c) If, (i) because of any change in law or in currently prevailing interpretations of the staff of the SEC, the Company is not permitted to effect the Exchange Offer, (ii) the Exchange Offer is
not consummated within 5 Business Days of the expiration of the Exchange Offer, or (iii) in the case of any holder of Private Exchange Notes or any Holder that participates in the Exchange Offer, such Holder notifies the Company within 20
Business Days after the consummation of the Exchange Offer that such Holder (A) is prohibited by law or currently prevailing interpretations of the staff of the SEC from participating in the Exchange Offer, (B) may not resell the Exchange
Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and the prospectus contained in the Exchange Offer Registration Statement is not available for such resales, or (C) is a broker-dealer and owns
outstanding Notes acquired directly from the Company or an affiliate of the Company, in the case of each of clauses (i) to and including (iii) of this sentence, then the Company shall promptly deliver to the Trustee (to deliver to the
Holders) written notice thereof (the “Shelf Notice”) and shall file a Shelf Registration pursuant to Section 3 hereof. 
  

	 	3.	Shelf Registration 

 If at
any time a Shelf Notice is delivered as contemplated by Section 2(c) hereof, then: 
 (a) Shelf
Registration. The Company shall promptly file with the SEC a Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415 covering all of the Registrable Securities (the “Initial Shelf
Registration”). The Company shall use its commercially reasonable efforts to file with the SEC the Initial Shelf Registration on or prior to the Filing Date. The Initial Shelf Registration shall be on Form S-1 or another appropriate
form permitting registration of such Registrable Securities for resale by Holders in the manner or manners designated by them (including, without limitation, one or more underwritten offerings). The Company shall not permit any securities other than
the Registrable Securities and the Guarantees and the Notes and the related guarantees to be included in the Initial Shelf Registration or any Subsequent Shelf Registration (as defined below). 

The Company shall use its respective commercially reasonable efforts to cause the Shelf Registration to be declared
effective under the Securities Act on or prior to the Effectiveness Date and to keep the Initial Shelf Registration continuously effective under the Securities Act until the earliest of (i) the date that is two years from the Issue Date,
(ii) such shorter period ending 

  
 -9-









 
when all Registrable Securities covered by the Initial Shelf Registration have been sold in the manner set forth and as contemplated in the Initial Shelf Registration or, if applicable, a
Subsequent Shelf Registration or (iii) the date upon which all Registrable Securities have been sold in compliance with Rule 144A (the “Effectiveness Period”); provided, however, that the Effectiveness Period in
respect of the Initial Shelf Registration shall be extended to the extent required to permit dealers to comply with the applicable prospectus delivery requirements of Rule 174 under the Securities Act and as otherwise provided herein. 

Notwithstanding anything to the contrary in this Agreement, at any time, the Company may delay the filing of any Initial
Shelf Registration Statement or delay or suspend the effectiveness thereof, for a reasonable period of time, but not in excess of 60 consecutive days or more than three (3) times during any calendar year (each, a “Shelf Suspension
Period”), if the Board of Directors of the Company determines reasonably and in good faith that the filing of any such Initial Shelf Registration Statement or the continuing effectiveness thereof would require the disclosure of non-public
material information that, in the reasonable judgment of the Board of Directors of the Company, would be detrimental to the Company if so disclosed or would otherwise materially adversely affect a financing, acquisition, disposition, merger or other
material transaction or such action is required by applicable law. 
 (b) Withdrawal of Stop Orders;
Subsequent Shelf Registrations. If the Initial Shelf Registration or any Subsequent Shelf Registration ceases to be effective for any reason at any time during the Effectiveness Period (other than because of the sale of all of the Securities
registered thereunder), the Company shall use its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall file an additional Shelf Registration Statement pursuant to
Rule 415 covering all of the Registrable Securities covered by and not sold under the Initial Shelf Registration or an earlier Subsequent Shelf Registration (each, a “Subsequent Shelf Registration”). If a Subsequent Shelf
Registration is filed, the Company shall use its commercially reasonable efforts to cause the Subsequent Shelf Registration to be declared effective under the Securities Act as soon as practicable after such filing and to keep such subsequent Shelf
Registration continuously effective for a period equal to the number of days in the Effectiveness Period less the aggregate number of days during which the Initial Shelf Registration or any Subsequent Shelf Registration was previously continuously
effective. As used herein the term “Shelf Registration” means the Initial Shelf Registration and any Subsequent Shelf Registration. 
 (c) Supplements and Amendments. The Company shall promptly supplement and amend the Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used
for such Shelf Registration, if required by the Securities Act, or if reasonably requested by the Holders of a majority in aggregate principal amount of the Registrable Securities (or their counsel) covered by such Registration Statement with
respect to the information included therein with respect to one or more of such Holders, or, if reasonably requested by any underwriter of such Registrable Securities, with respect to the information included therein with respect to such
underwriter. 
  

	 	4.	Additional Interest 

 (a)
The Company and the Initial Purchasers agree that the Holders will suffer damages if the Company fails to fulfill its obligations under Section 2 or Section 3 hereof and that it would not be feasible to ascertain the extent of such damages
with precision. Accordingly, the Company agrees to pay, jointly and severally, as liquidated damages, additional interest on the Notes (“Additional Interest”) 

  
 -10-









 
if (A) the Exchange Offer Registration Statement has not been declared effective on or prior to the 365th day after the Issue Date, (B) the Company has not exchanged Exchange Securities
for all Securities validly tendered in accordance with the terms of the Exchange Offer on or prior to 30 Business Days after the Effectiveness Date for the Exchange Offer Registration Statement, (C) the Company is required to file a Shelf
Registration Statement and such Shelf Registration Statement is not declared effective on or prior to the 90th day after the date such Shelf Registration Statement filing was requested or required or (D) if applicable, a Shelf Registration has
been declared effective and such Shelf Registration ceases to be effective at any time during the Effectiveness Period (other than because of the sale of all of the Securities registered thereunder). Any Additional Interest shall accrue on the
principal amount of the Notes at a rate of 0.25% per annum (which rate will be increased by an additional 0.25% per annum for each subsequent 90 day period that such Additional Interest continues to accrue, provided that the rate at which
such Additional Interest accrues may in no event exceed 1.00% per annum) (such Additional Interest to be calculated by the Company) commencing on the (w) 366th day after the Issue Date, in the case of (A) above, (x) 31st Business
Day after the Effectiveness Date for the Exchange Offer Registration Statement, in the case of (B) above, (y) the 366th day after the date such Shelf Registration Statement filing was requested or required in the case of (C) above or
(z) the day such Shelf Registration ceases to be effective in the case of (D) above; provided, however, that upon the effectiveness of the applicable Exchange Offer Registration Statement (in the case of (A) of this
Section 4), upon the exchange of the Exchange Securities for all Securities tendered (in the case of clause (B) of this Section 4), upon the effectiveness of the applicable Shelf Registration Statement (in the case of (C) of this
Section 4), or upon the effectiveness of the applicable Shelf Registration Statement which had ceased to remain effective (in the case of (D) of this Section 4), Additional Interest on the Notes in respect of which such events relate
as a result of such clause (or the relevant subclause thereof), as the case may be, shall cease to accrue. Notwithstanding any other provisions of this Section 4, (i) the Company shall not be obligated to pay Additional Interest in respect
of an event described in Section 4(a)(C) during a Shelf Suspension Period permitted by Section 3(a) hereof, and (ii) no Additional Interest shall accrue on the Notes following the second anniversary of the Issue Date. 

(b) The Company shall notify the Trustee within one Business Day after each and every date on which an event occurs in respect of which
Additional Interest is required to be paid (an “Event Date”). Any amounts of Additional Interest due pursuant to (a) of this Section 4 will be payable in cash semiannually on each February 1 and August 1 (to the
holders of record on the January 15 and July 15 immediately preceding such dates), commencing with the first such date occurring after any such Additional Interest commences to accrue. The amount of Additional Interest will be determined
by the Company by multiplying the applicable Additional Interest rate by the principal amount of the Registrable Securities, 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 365 day year comprised of twelve 30 day months and, in the case of a partial month, the actual number of days elapsed), and the denominator of which is 365. 

(c) The liquidated damages set forth in this Section 4 shall be the exclusive remedy for the Holders if the Company fails to fulfill
its obligations under Section 2 or Section 3 thereof. 
  

	 	5.	Registration Procedures 


In connection with the filing of any Registration Statement pursuant to Section 2 or 3 hereof, the Company shall effect such
registrations to permit the sale of the securities covered thereby in accordance with the intended method or methods of disposition thereof, and pursuant thereto and in connection with any Registration Statement filed by the Company hereunder the
Company shall: 

  
 -11-









 (a) Prepare and file with the SEC (prior to the applicable Filing Date in
the case of a Shelf Registration), a Registration Statement or Registration Statements as prescribed by Section 2 or 3 hereof, and use its commercially reasonable efforts to cause each such Registration Statement to become effective and remain
effective as provided herein; provided, however, that if (1) such filing is pursuant to Section 3 hereof or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof
is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period relating thereto from whom the Company has received prior written notice that it will be a
Participating Broker-Dealer in the Exchange Offer, before filing any Registration Statement or Prospectus or any amendments or supplements thereto, the Company shall furnish to and afford counsel for the Holders of the Registrable Securities covered
by such Registration Statement (with respect to a Registration Statement filed pursuant to Section 3 hereof) or counsel for such Participating Broker-Dealer (with respect to any such Registration Statement), as the case may be, and counsel to
the managing underwriters, if any, a reasonable opportunity to review copies of all such documents (including copies of any documents to be incorporated by reference therein and all exhibits thereto) proposed to be filed (in each case at least three
business days prior to such filing). The Company shall not file any Registration Statement or Prospectus or any amendments or supplements thereto if the Holders of a majority in aggregate principal amount of the Registrable Securities covered by
such Registration Statement, their counsel, or the managing underwriters, if any, shall reasonably object. 
 (b)
Prepare and file with the SEC such amendments and post-effective amendments to each Shelf Registration Statement or Exchange Offer Registration Statement, as the case may be, as may be necessary to keep such Registration Statement continuously
effective for the Effectiveness Period, the Applicable Period or until consummation of the Exchange Offer, as the case may be; cause the related Prospectus to be supplemented by any Prospectus supplement required by applicable law, and as so
supplemented to be filed pursuant to Rule 424; and comply with the provisions of the Securities Act and the Exchange Act applicable to it with respect to the disposition of all securities covered by such Registration Statement as so amended or
in such Prospectus as so supplemented and with respect to the subsequent resale of any securities being sold by an Participating Broker-Dealer covered by any such Prospectus in all material respects. The Company shall be deemed not to have used its
commercially reasonable efforts to keep a Registration Statement effective if it voluntarily takes any action that is reasonably expected to result in selling Holders of the Registrable Securities covered thereby or Participating Broker-Dealers
seeking to sell Exchange Securities not being able to sell such Registrable Securities or such Exchange Securities during that period unless such action is required by applicable law or permitted by this Agreement. 

(c) If (1) a Shelf Registration is filed pursuant to Section 3 hereof or (2) a Prospectus contained in the
Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period relating thereto
from whom the Company has received written notice that it will be a Participating Broker-Dealer in the Exchange Offer, notify the selling Holders of Registrable Securities (with respect to a Registration Statement filed pursuant to Section 3
hereof), or each such Participating Broker-Dealer (with respect to any such Registration Statement), as the case may be, their counsel and the managing underwriters, if any, promptly (but in any event within three Business Days), and confirm such
notice in writing, (i) when a Prospectus or any Prospectus supplement or post-effective amendment has been filed, and, with respect to a Registration Statement or any post-effective amendment, when the same has become effective under the
Securities Act (including in such notice a written statement that

any Holder may, upon request, obtain, at the sole expense of the Company, one conformed copy of such Registration Statement or post-effective amendment including financial statements and
schedules, documents incorporated or deemed to be incorporated by reference and exhibits), (ii) of the issuance by the SEC of any stop order suspending the effectiveness of a Registration Statement or of any order preventing or suspending the
use of any preliminary prospectus or the initiation of any proceedings for that purpose, (iii) if at any time when a prospectus is required by the Securities Act to be delivered in connection with sales of the Registrable Securities or resales
of Exchange Securities by Participating Broker-Dealers the representations and warranties of the Company contained in any agreement (including any underwriting agreement) contemplated by Section 5(m) hereof cease to be true and correct,
(iv) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of a Registration Statement or any of the Registrable Securities or the Exchange Securities to be sold by
any Participating Broker-Dealer for offer or sale in any jurisdiction, or the initiation or threatening of any proceeding for such purpose, (v) of the happening of any event, the existence of any condition or any information becoming known that
makes any statement made in such Registration Statement or related Prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires the making of any changes in or amendments
or supplements to such Registration Statement, Prospectus or documents so that, in the case of the Registration Statement, it will not contain any 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 not misleading, and that in the case of the Prospectus, it will not contain any 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, and (vi) of the Company’s determination that a post-effective amendment to a Registration Statement would be appropriate. 

(d) Use its commercially reasonable efforts to prevent the issuance of any order suspending the effectiveness of a
Registration Statement or of any order preventing or suspending the use of a Prospectus or suspending the qualification (or exemption from qualification) of any of the Registrable Securities or the Exchange Securities to be sold by any Participating

 (f)
If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act
by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, furnish to each selling Holder of Registrable Securities (with respect to a Registration Statement filed pursuant to Section 3 hereof) and to

expense of the Company, one conformed copy of the Registration Statement or Registration Statements and each post-effective amendment thereto, including financial statements and schedules, and,
if requested, all documents incorporated or deemed to be incorporated therein by reference and all exhibits. 

(g) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the
Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, deliver to each
selling Holder of Registrable Securities (with respect to a Registration Statement filed pursuant to Section 3 hereof), or each such Participating Broker-Dealer (with respect to any such Registration Statement), as the case may be, their

selling Holders of Registrable Securities or each such Participating Broker-Dealer, as the case may be, and the underwriters or agents, if any, and dealers, if any, in connection with the offering and sale of the Registrable Securities covered by,
or the sale by Participating Broker-Dealers of the Exchange Securities pursuant to, such Prospectus and any amendment or supplement thereto. 
 (h) Prior to any public offering of Registrable Securities or any delivery of a Prospectus contained in the Exchange Offer Registration Statement by any Participating Broker-Dealer who seeks to sell
Exchange Securities during the Applicable Period, use its commercially reasonable efforts to register or qualify, and to cooperate with the selling Holders of Registrable Securities or each such Participating Broker-Dealer, as the case may be, the
managing underwriter or underwriters, if any, and their respective counsel in connection with the registration or qualification (or exemption from such registration or qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as any selling Holder, Participating Broker-Dealer, or the managing underwriter or underwriters reasonably request in writing; provided, however, that where
Exchange Securities held by Participating Broker-Dealers or Registrable Securities are offered other than through an underwritten offering, the Company agrees to cause its counsel to perform Blue Sky investigations and file registrations and
qualifications required to be filed pursuant to this Section 5(h), keep each such registration or qualification (or exemption therefrom) effective during the period such Registration Statement is required to be kept effective and do any and all
other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Exchange Securities held by Participating Broker-Dealers or the Registrable Securities covered by the applicable Registration Statement;
provided, however, that the Company shall not be required to (A) qualify generally to do business in any jurisdiction where it is not then so qualified, (B) take any action that would subject it to general service of process
in any such jurisdiction where it is not then so subject or (C) subject itself to taxation in excess of a nominal dollar amount in any such jurisdiction where it is not then so subject. 

(i) If a Shelf Registration is filed pursuant to Section 3 hereof, cooperate with the selling Holders of Registrable
Securities and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be sold, which certificates shall not bear any restrictive legends and shall be
in a form eligible for deposit with The Depository Trust Company; and enable such Registrable Securities to be in such denominations (subject to applicable requirements contained in the Indenture) and registered in such names as the managing
underwriter or underwriters, if any, or Holders may request. 

  
 -14-









 (j) Use its commercially reasonable efforts to cause the Registrable
Securities covered by the Registration Statement to be registered with or approved by such other U.S. governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter or underwriters, if any, to
consummate the disposition of such Registrable Securities, except as may be required solely as a consequence of the nature of such selling Holder’s business, in which case the Company will cooperate in all respects with the filing of such
Registration Statement and the granting of such approvals. 
 (k) If (1) a Shelf Registration is filed
pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is required to be delivered under the Securities Act by any Participating Broker-Dealer who
seeks to sell Exchange Securities during the Applicable Period, upon the occurrence of any event contemplated by Section 5(c)(v) or 5(c)(vi) hereof, as promptly as practicable prepare and (subject to Section 5(a) hereof) file with the SEC,
at the sole expense of the Company, a supplement or post-effective amendment to the Registration Statement or a supplement to the related Prospectus or any document incorporated therein by reference, or file any other required document so that, as
thereafter delivered to the purchasers of the Registrable Securities being sold thereunder (with respect to a Registration Statement filed pursuant to Section 3 hereof) or to the purchasers of the Exchange Securities to whom such Prospectus
will be delivered by a Participating Broker-Dealer (with respect to any such Registration Statement), any such Prospectus will not 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, in the light of the circumstances under which they were made, not misleading. 
 (l) Prior to the effective date of the first Registration Statement relating to the Registrable Securities, (i) provide the Trustee with certificates for the Registrable Securities in a form eligible
for deposit with The Depository Trust Company and (ii) provide a CUSIP number for the Registrable Securities. 
 (m) In connection with any underwritten offering of Registrable Securities pursuant to a Shelf Registration, enter into an underwriting agreement as is customary in underwritten offerings of debt
securities similar to the Securities (including, without limitation, a customary condition to the obligations of the underwriters that the underwriters shall have received “cold comfort” letters and updates thereof in form, scope and
substance reasonably satisfactory to the managing underwriter or underwriters from the independent certified public accountants of the Company (and, if necessary, any other independent certified public accountants of the Company, or of any business
acquired by the Company, for which financial statements and financial data are, or are required to be, included or incorporated by reference in the Registration Statement), addressed to each of the underwriters, such letters to be in customary form
and covering matters of the type customarily covered in “cold comfort” letters in connection with underwritten offerings of debt securities similar to the Securities), and take all such other actions as are reasonably requested by the
managing underwriter or underwriters in order to expedite or facilitate the registration or the disposition of such Registrable Securities and, in such connection, (i) make such representations and warranties to, and covenants with, the
underwriters with respect to the business of the Company (including any acquired business, properties or entity, if applicable), and the Registration Statement, Prospectus and documents, if any, incorporated or deemed to be incorporated by reference
therein, in each case, as are customarily made by Issuer to underwriters in 

  
 -15-









 
underwritten offerings of debt securities similar to the Securities, and confirm the same in writing if and when requested; (ii) obtain the written opinions of counsel to the Company, and
written updates thereof in form, scope and substance reasonably satisfactory to the managing underwriter or underwriters, addressed to the underwriters covering the matters customarily covered in opinions reasonably requested in underwritten
offerings; and (iii) if an underwriting agreement is entered into, the same shall contain indemnification provisions and procedures no less favorable to the sellers and underwriters, if any, than those set forth in Section 7 hereof (or
such other provisions and procedures reasonably acceptable to Holders of a majority in aggregate principal amount of Registrable Securities covered by such Registration Statement and the managing underwriter or underwriters or agents, if any). The
above shall be done at each closing under such underwriting agreement, or as and to the extent required thereunder. 
 (n) If (1) a Shelf Registration is filed pursuant to Section 3 hereof, or (2) a Prospectus contained in the Exchange Offer Registration Statement filed pursuant to Section 2 hereof is
required to be delivered under the Securities Act by any Participating Broker-Dealer who seeks to sell Exchange Securities during the Applicable Period, make available for inspection by any Initial Purchaser, any selling Holder of such Registrable
Securities being sold (with respect to a Registration Statement filed pursuant to Section 3 hereof), or each such Participating Broker-Dealer, as the case may be, any underwriter participating in any such disposition of Registrable Securities,
if any, and any attorney, accountant or other agent retained by any such selling Holder or each such Participating Broker-Dealer (with respect to any such Registration Statement), as the case may be, or underwriter (any such Initial Purchasers,
Holders, Participating Broker-Dealers, underwriters, attorneys, accountants or agents, collectively, the “Inspectors”), upon written request, at the offices where normally kept, during reasonable business hours, all pertinent
financial and other records, pertinent corporate documents and instruments of the Company and subsidiaries of the Company (collectively, the “Records”), as shall be reasonably necessary to enable them to exercise any applicable due
diligence responsibilities, and cause the officers, directors and employees of the Company and any of its subsidiaries to supply all information (“Information”) reasonably requested by any such Inspector in connection with such due
diligence responsibilities. Each Inspector shall agree in writing that it will keep the Records and Information confidential, to use the Information only for due diligence purposes, to abstain from using the Information as the basis for any market
transactions in Securities of the Company and that it will not disclose any of the Records or Information that the Company determines, in good faith, to be confidential and notifies the Inspectors in writing are confidential unless (i) the
disclosure of such Records or Information is necessary to avoid or correct a misstatement or omission in such Registration Statement or Prospectus, (ii) the release of such Records or Information is ordered pursuant to a subpoena or other order
from a court of competent jurisdiction, (iii) disclosure of such Records or Information is necessary or advisable, in the opinion of counsel for any Inspector, in connection with any action, claim, suit or proceeding, directly or indirectly,
involving or potentially involving such Inspector and arising out of, based upon, relating to, or involving this Agreement or the Purchase Agreement, or any transactions contemplated hereby or thereby or arising hereunder or thereunder, or
(iv) the information in such Records or Information has been made generally available to the public other than by an Inspector or an “affiliate” (as defined in Rule 405) thereof; provided, however, that prior notice
shall be provided as soon as practicable to the Company of the potential disclosure of any information by such Inspector pursuant to clauses (i) or (ii) of this sentence to permit the Company to obtain a protective order (or waive the
provisions of this paragraph (o)) and that such Inspector shall take such actions as are reasonably necessary to protect the confidentiality of such information (if practicable) to the extent such action is otherwise not inconsistent with, an
impairment of or in derogation of the rights and interests of the Holder or any Inspector. 

  
 -16-









 (o) Provide an indenture trustee for the Registrable Securities or the
Exchange Securities, as the case may be, and cause the Indenture or the trust indenture provided for in Section 2(a) hereof, as the case may be, to be qualified under the TIA not later than the effective date of the first Registration Statement
relating to the Registrable Securities; and in connection therewith, cooperate with the trustee under any such indenture and the Holders of the Registrable Securities, to effect such changes (if any) to such indenture as may be required for such
indenture to be so qualified in accordance with the terms of the TIA; and execute, and use its commercially reasonable efforts to cause such trustee to execute, all documents as may be required to effect such changes, and all other forms and
documents required to be filed with the SEC to enable such indenture to be so qualified in a timely manner. 

(p) Comply in all material respects with all applicable rules and regulations of the SEC and make generally available to
its securityholders with regard to any applicable Registration Statement, a consolidated earning statement satisfying the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule promulgated under the
Securities Act) no later than 45 days after the end of any fiscal quarter (or 90 days after the end of any 12-month period if such period is a fiscal year) (i) commencing at the end of any fiscal quarter in which Registrable
Securities are sold to underwriters in a firm commitment or best efforts underwritten offering and (ii) if not sold to underwriters in such an offering, commencing on the first day of the first fiscal quarter of the Company, after the effective
date of a Registration Statement, which statements shall cover said 12-month periods; provided that this requirement shall be deemed satisfied by the Company complying with Section 4.03 of the Indenture. 

(q) Upon consummation of the Exchange Offer or a Private Exchange, obtain an opinion of counsel to the Company, in a form
customary for underwritten transactions, addressed to the Trustee for the benefit of all Holders of Registrable Securities participating in the Exchange Offer or the Private Exchange, as the case may be, that the Exchange Securities or Private
Exchange Notes (and the related Guarantees), as the case may be, the related guarantee and the related indenture constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with its respective terms,
subject to customary exceptions and qualifications. If the Exchange Offer or a Private Exchange is to be consummated, upon delivery of the Registrable 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 Notes (and the related Guarantees), as the case may be, the Company shall mark, or cause to be marked, on such Registrable Securities that such Registrable Securities are being cancelled
in exchange for the Exchange Securities or the Private Exchange Notes (and the related Guarantees), as the case may be; in no event shall such Registrable Securities be marked as paid or otherwise satisfied. 

(r) Use commercially reasonable efforts to cooperate with each seller of Registrable Securities covered by any
Registration Statement and each underwriter, if any, participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with the Financial Industry Regulatory Authority,
Inc. (the “FINRA”). 
 (s) Use its respective commercially reasonable efforts to take all other
steps reasonably necessary to effect the registration of the Exchange Securities and/or Registrable Securities covered by a Registration Statement contemplated hereby. 

  
 -17-









 The Company may require each seller of Registrable Securities as to which any registration
is being effected to furnish to the Company such information regarding such seller and the distribution of such Registrable Securities as the Company may, from time to time, reasonably request. The Company may exclude from such registration the
Registrable Securities of any seller so long as such seller fails to furnish such information within a reasonable time after receiving such request. Each seller as to which any Shelf Registration is being effected agrees to furnish promptly to the
Company all information required to be disclosed in order to make the information previously furnished to the Company by such seller not materially misleading. 
 If any such Registration Statement refers to any Holder by name or otherwise as the holder of any securities of the Company, then such Holder shall have the right to require (i) the insertion therein
of language, in form and substance reasonably satisfactory to such Holder, to the effect that the holding by such Holder of such securities is not to be construed as a recommendation by such Holder of the investment quality of the securities covered
thereby and that such holding does not imply that such Holder will assist in meeting any future financial requirements of the Company, or (ii) in the event that such reference to such Holder by name or otherwise is not required by the
Securities Act or any similar federal statute then in force, the deletion of the reference to such Holder in any amendment or supplement to the Registration Statement filed or prepared subsequent to the time that such reference ceases to be
required. 
 Each Holder of Registrable Securities and each Participating Broker-Dealer agrees by its acquisition of such
Registrable Securities or Exchange Securities to be sold by such Participating Broker-Dealer, as the case may be, that, upon actual receipt of any notice from the Company of the happening of any event of the kind described in Section 5(c)(ii),
5(c)(iv), 5(c)(v), or 5(c)(vi) hereof, such Holder will forthwith discontinue disposition of such Registrable Securities covered by such Registration Statement or Prospectus or Exchange Securities to be sold by such Holder or Participating
Broker-Dealer, as the case may be, until such Holder’s or Participating Broker-Dealer’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof, or until it is advised in writing (the
“Advice”) by the Company that the use of the applicable Prospectus may be resumed, and has received copies of any amendments or supplements thereto. In the event that the Company shall give any such notice, each of the Applicable
Period and the Effectiveness Period shall be extended by the number of days during such periods from and including the date of the giving of such notice to and including the date when each seller of Registrable Securities covered by such
Registration Statement or Exchange Securities to be sold by such Participating Broker-Dealer, as the case may be, shall have received (x) the copies of the supplemented or amended Prospectus contemplated by Section 5(k) hereof or
(y) the Advice. 
  

	 	6.	Registration Expenses 


All fees and expenses incident to the performance of or compliance with this Agreement by the Company of its obligations under Sections 2,
3, 4, 5 and 8 shall be borne by the Company, whether or not the Exchange Offer Registration Statement or any Shelf Registration Statement is filed or becomes effective or the Exchange Offer is consummated, including, without limitation, (i) all
registration and filing fees (including, without limitation, (A) fees with respect to filings required to be made with FINRA in connection with an underwritten offering and (B) fees and expenses of compliance with state securities or Blue
Sky laws (including, without limitation, reasonable fees and disbursements of counsel in connection with Blue Sky qualifications of the Registrable Securities or Exchange Securities and determination of the eligibility of the Registrable Securities
or Exchange Securities for investment under the laws of such jurisdictions in the United States (x) where the holders of Registrable Securities are located, in the case of the Exchange Securities, or (y) as provided in Section 5(h)
hereof, in the case of Registrable Securities or

Exchange Securities to be sold by a Participating Broker-Dealer during the Applicable Period)), (ii) printing expenses, including, without limitation, printing prospectuses if the printing
of prospectuses is requested by the managing underwriter or underwriters, if any, by the Holders of a majority in aggregate principal amount of the Registrable Securities included in any Registration Statement or in respect of Registrable Securities
or Exchange Securities to be sold by any Participating Broker-Dealer during the Applicable Period, as the case may be, (iii) fees and expenses of the Trustee, any exchange agent and their counsel, (iv) fees and disbursements of counsel for
the Company and, in the case of a Shelf Registration, reasonable fees and disbursements of one special counsel for all of the sellers of Registrable Securities selected by the Holder of a majority in aggregate principal amount of Registrable
Securities covered by such Shelf Registration (which counsel shall be reasonably satisfactory to the Company) exclusive of any counsel retained pursuant to Section 7 hereof), (v) fees and disbursements of all independent certified public
accountants referred to in Section 5(m) hereof (including, without limitation, the expenses of any “cold comfort” letters required by or incident to such performance), (vi) rating agency fees, if any, and any fees associated with
making the Registrable Securities or Exchange Securities eligible for trading through The Depository Trust Company, (vii) Securities Act liability insurance, if the Company desires such insurance, (viii) fees and expenses of all other
Persons retained by the Company, (ix) internal expenses of the Company (including, without limitation, all salaries and expenses of officers and employees of the Company performing legal or accounting duties), (x) the expense of any annual
audit, (xi) any fees and expenses incurred in connection with the listing of the securities to be registered on any securities exchange, and the obtaining of a rating of the securities, in each case, if applicable and (xii) the expenses
relating to printing, word processing and distributing all Registration Statements, underwriting agreements, indentures and any other documents necessary in order to comply with this Agreement. 

 

	 	7.	Indemnification and Contribution. 

 (a) The Company and the Guarantors jointly and severally agree, to indemnify and hold harmless each Holder of Registrable Securities, and each Participating Broker-Dealer selling Exchange Securities
during the Applicable Period, and each Person, if any, who controls such Person or its affiliates within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, a “Participant”) against any losses,
claims, damages or liabilities, joint or several, to which any Participant may become subject under the Securities Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon: 
 (i) any untrue statement or alleged untrue statement of any material fact contained
in any Registration Statement (or any amendment thereto), or Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus; or 

(ii) the omission or alleged omission to state, in any Registration Statement (or any amendment thereto), or Prospectus
(as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus or any other document or any amendment or supplement thereto, a material fact required to be stated therein or
necessary to make the statements therein not misleading, 
 except, in each case, insofar as such losses, claims, damages or
liabilities are arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser or any Holder furnished to the
Company in writing through the Initial Purchasers or any selling Holder expressly for use therein; 

  
 -19-









 
and agree (subject to the limitations set forth in the proviso to this sentence) to reimburse, as incurred, the Participant for any reasonable legal or other expenses incurred by the Participant
in connection with investigating, defending against or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, neither the Company nor the Guarantors will be liable in
any such case to the extent that any 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 any Registration Statement (or any amendment
thereto), or Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto) or any preliminary prospectus or any amendment or supplement thereto in reliance upon and in conformity with written
information relating to any Participant furnished to the Company by such Participant specifically for use therein. The indemnity provided for in this Section 7 will be in addition to any liability that the Company may otherwise have to the
indemnified parties. The Company and the Guarantors shall not be liable under this Section 7 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened
claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or
consent is consented to by the Company and the Guarantors, which consent shall not be unreasonably withheld. 
 (b) Each
Participant, severally and not jointly, agrees to indemnify and hold harmless the Company, the Guarantors, their respective directors (or equivalent), their respective officers who sign any Registration Statement and each person, if any, who
controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which the Company, the Guarantors or any such director, officer or controlling person
may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any
material fact contained in any Registration Statement, Prospectus, any amendment or supplement thereto, or any preliminary prospectus, or (ii) the omission or the alleged omission to state therein a material fact necessary to make the
statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information
concerning such Participant, furnished to the Company by or on behalf of such Participant, specifically for use therein; and subject to the limitation set forth immediately preceding this clause, will reimburse, as incurred, any reasonable legal or
other expenses incurred by the Company, the Guarantors or any such director, officer or controlling person in connection with investigating or defending against or appearing as a third party witness in connection with any such loss, claim, damage,
liability or action in respect thereof. The indemnity provided for in this Section 7 will be in addition to any liability that the Participants may otherwise have to the indemnified parties. The Participants shall not be liable under this
Section 7 to any indemnified party regarding any settlement or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution
may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent is consented to by the Participants, which consent shall not be unreasonably
withheld. The Company and the Guarantors shall not, without the prior written consent of such Participant, effect any settlement or compromise of any pending or threatened proceeding in respect of which such Participant is or could have been a
party, or indemnity could have been sought hereunder by such Participant, unless such settlement (A) includes an unconditional written release of such Participant, in form and substance reasonably satisfactory to such Participant, from all
liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of such Participant. 

  
 -20-









 (c) Promptly after receipt by an indemnified party under this Section 7 of notice of
the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party of the commencement thereof in writing; but the omission
to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the
indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and
(b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which
indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified
party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local
counsel) to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate
counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest (based on the advice of counsel to the indemnified person); (ii) such action
includes both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded (based on the advice of counsel to the indemnified person) that there may be legal defenses available to it and/or other
indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified
party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. It is understood and agreed
that the indemnifying person shall not, in connection with any proceeding or separate but related or substantially similar proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm (in addition to any local counsel) representing the indemnified parties under paragraph (a) or paragraph (b) of this Section 7, as the case may be, who are parties to such
action or actions. Any such separate firm for any Participants shall be designated in writing by Participants who sold a majority in interest of the Registrable Securities and Exchange Securities sold by all such Participants in the case of
paragraph (a) of this Section 7 or the Company in the case of paragraph (b) of this Section 7. In the event that any Participants are indemnified persons collectively entitled, in connection with a proceeding or separate but
related or substantially similar proceedings in a single jurisdiction, to the payment of fees and expenses of a single separate firm under this Section 7(c), and any such Participants cannot agree to a mutually acceptable separate firm to act
as counsel thereto, then such separate firm for all such Indemnified Persons shall be designated in writing by Participants who sold a majority in interest of the Registrable Securities and Exchange Securities sold by all such Participants. An
indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any statement as to, or any admission of, fault, culpability or failure to act by or on behalf of any indemnified party. All fees and
expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. 

  
 -21-









 (d) After notice from the indemnifying party to such indemnified party of its election so
to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses, other
than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the third sentence of
paragraph (c) of this Section 7 or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. After such notice from the indemnifying party to
such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be
unreasonably withheld), unless such indemnified party waived in writing its rights under this Section 7, in which case the indemnified party may effect such a settlement without such consent. 

(e) In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 7 is unavailable to,
or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof) (other than by virtue of the failure of an indemnified party to notify the indemnifying party of its
right to indemnification pursuant to paragraph (a) or (b) of this Section 7, where such failure materially prejudices the indemnifying party (through the forfeiture of substantial rights or defenses)), each indemnifying party, in
order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect (i) the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the offering of the Securities or (ii) if the allocation provided by the foregoing
clause (i) is not permitted by applicable law, not only such relative benefits 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 or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company and the Guarantors on the one hand and such Participant on the
other shall be deemed to be in the same proportion that the total net proceeds from the offering (before deducting expenses) of the Securities received by the Company bear to the total discounts and commissions received by such Participant in
connection with the sale of the Securities (or if such Participant did not receive discounts or commissions, the value or receiving the Securities). 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 the Participants on the other, the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The parties agree that it would not
be equitable if the amount of such contribution were determined by pro rata or per capita allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this
paragraph (e). Notwithstanding any other provision of this paragraph (e), no Participant shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation or net proceeds on the
sale of Securities received by such Participant in connection with the sale of the Securities, less the aggregate amount of any damages that such Participant has otherwise been required to pay by reason of the untrue or alleged untrue statements or
the omissions or alleged omissions to state a material fact, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 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 a Participant within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as
the Participants, and each director of the Company 

  
 -22-









 
and the Guarantors, each officer of the Company and the Guarantors and each person, if any, who controls the Company and the Guarantors within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. 
  

	 	8.	Rule 144A 

 The Company
covenants and agrees that it will use commercially reasonable efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder in a timely manner in
accordance with the requirements of the Securities Act and the Exchange Act and, if at any time the Company is not required to file such reports, the Company will, upon the request of any Holder or beneficial owner of Registrable Securities, make
available such information necessary to permit sales pursuant to Rule 144A. The Company further covenants and agrees, for so long as any Registrable Securities remain outstanding that they will take such further action as any Holder of
Registrable Securities may reasonably request, all to the extent required from time to time to enable such holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by
Rule 144A unless the Company is then subject to Section 13 or 15(d) of the Exchange Act and reports filed thereunder satisfy the information requirements of Rule 144A then in effect. 

 

	 	9.	Underwritten Registrations 


The Company shall not be required to assist in an underwritten offering unless requested by the Holders of a majority in aggregate
principal amount of the Registrable Securities. If any of the Registrable 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 manage
the offering will be selected by the Holders of a majority in aggregate principal amount of such Registrable Securities included in such offering and shall be reasonably acceptable to the Company. 

No Holder of Registrable Securities may participate in any underwritten registration hereunder unless such Holder (a) agrees to sell
such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all questionnaires, powers of attorney,
indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements. 
  

	 	10.	Miscellaneous 

 (a) No
Inconsistent Agreements. The Company has not as of the date hereof, and the Company shall not, after the date of this Agreement, enter into any agreement with respect to any of its securities that is inconsistent with the rights granted to the
Holders of Registrable Securities in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the
Company other issued and outstanding securities under any such agreements. The Company will not enter into any agreement (other than the Registration Rights Agreement dated as of the date hereof in respect of the Notes) with respect to any of its
securities which will grant to any Person piggy-back registration rights with respect to any Registration Statement. 
 (b)
Adjustments Affecting Registrable Securities. The Company shall not, directly or indirectly, take any action with respect to the Registrable Securities as a class that would adversely affect the ability of the Holders of Registrable
Securities to include such Registrable Securities in a registration undertaken pursuant to this Agreement. 

  
 -23-









 (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, otherwise than with the prior written consent of (I) the Company, and (II) (A) the Holders of not less than a majority in
aggregate principal amount of the then outstanding Registrable Securities and (B) in circumstances that would adversely affect the Participating Broker-Dealers, the Participating Broker-Dealers holding not less than a majority in aggregate
principal amount of the Exchange Notes held by all Participating Broker-Dealers; provided, however, that Section 7 and this Section 10(c) may not be amended, modified or supplemented without the prior written consent of each
Holder and each Participating Broker-Dealer (including any person who was a Holder or Participating Broker-Dealer of Registrable Securities or Exchange Securities, as the case may be, disposed of pursuant to any Registration Statement) affected by
any such amendment, modification or supplement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of Holders of Registrable Securities whose
securities are being sold pursuant to a Registration Statement and that does not directly or indirectly affect, impair, limit or compromise the rights of other Holders of Registrable Securities may be given by Holders of at least a majority in
aggregate principal amount of the Registrable Securities being sold pursuant to such Registration Statement. 
 (d)
