 REGISTRATION RIGHTS AGREEMENT 

This Registration Rights Agreement (this “Agreement”) is dated as of November 24, 2014, by and 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. (the “Initial
Purchaser”). 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 November 19, 2014, by and among certain of the Issuers and the Initial Purchaser (the “Purchase Agreement”), which provides for, among other things, the sale
by the Company to the Initial Purchaser of $25,000,000 aggregate principal amount of the Company’s 7.375% Senior Notes due 2019 (the “Notes”). The Notes are issued under that certain Indenture, dated as of January 28,
2011, as supplemented by that certain First Supplemental Indenture, dated as of May 6, 2011, that certain Second Supplemental Indenture, dated as of January 15, 2013, and that certain Third Supplemental Indenture, dated as of
November 19, 2014 (as amended or supplemented from time to time, the “Indenture”), by and 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 unsecured basis the Company’s obligations under the Notes and the Indenture. The Notes and the
Guarantees are collectively referred to as the “Securities.” The Company previously issued and sold, and the Guarantors have guaranteed, $250,000,000 in aggregate principal amount of the Company’s 7.375% Senior Notes due 2019
under the Indenture (the “Existing Securities”). The Notes constitute an issuance of Additional Notes (as defined in the Indenture) under the Indenture. In order to induce the Initial Purchaser 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 Purchaser 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 Purchaser’s 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 and (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 that 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 20 Business Days (or longer if required by applicable law) after the date of
commencement of the Exchange Offer; and (z) consummate the Exchange Offer on or prior to the 5th Business Day following the expiration of the Exchange Offer. 

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; (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 as to which Section 2(c) is applicable, and the Company shall have no further obligation to register Registrable Securities (other than Registrable Securities as to which
Section 2(c) is applicable) pursuant to Section 3 hereof. 

  
 -5- 

 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”). 

In connection with the Exchange Offer, the Company shall: 

(1) mail, or cause to be mailed or otherwise distributed, 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 its commercially reasonable efforts to keep the Exchange Offer open for not less than 20 Business Days from the date
that the Exchange Offer is commenced (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 expiration of the Exchange Offer; and 
 (5) otherwise
comply in all material respects with all laws, rules and regulations applicable to the Exchange Offer. 

  
 -6- 

 As soon as practicable after the close of the Exchange Offer, the Company shall: 

(1) accept for exchange all Registrable Securities validly tendered and not validly withdrawn pursuant to the Exchange Offer;

 (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 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. 

The Exchange Offer shall not be subject to any conditions, other than that (i) the Exchange Offer 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, 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 deems necessary
for the consummation of the Exchange Offer. 
 The Exchange Securities (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 and the Notes shall vote and consent together on all matters as one class and that none of the 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 Registrable Securities, such Holder notifies the Company prior to the 20th Business Day 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 within the meaning of the Securities Act, 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. 

  
 -7- 

 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 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 

  
 -8- 

 
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 Purchaser 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”) 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 (w) the 366th day after the Issue Date, in the case of (A) above,
(x) the 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 

  
 -9- 

 
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: 
 (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

  
 -10- 

 
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 any
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 

  
 -11- 

 
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 Broker-Dealer, for sale in any jurisdiction. 
 (e) If a Shelf
Registration is filed pursuant to Section 3 and if requested during the Effectiveness Period by the managing underwriter or underwriters (if any) or the Holders of a majority in aggregate principal amount of the Registrable Securities being
sold in connection with an underwritten offering, (i) as promptly as practicable incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or underwriters (if any), such Holders or counsel
for either of them reasonably request to be included therein, (ii) make all required filings of such prospectus supplement or such post-effective amendment as soon as practicable after the Company has received notification of the matters to be
incorporated in such prospectus supplement or post-effective amendment, and (iii) supplement or make amendments to such Registration Statement; provided, however, that the Company shall not be required to take any action pursuant to this
Section 5(e) that would in the reasonable opinion of counsel for the Company, violate any applicable law. 
 (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 

  
 -12- 

 
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 each such Participating Broker-Dealer who so requests (with respect to any such Registration Statement) and to their respective counsel and each managing underwriter, if any, at the sole 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 respective counsel, and the underwriters, if any, at the sole expense of the Company, as many copies of the Prospectus or Prospectuses (including each form of preliminary prospectus) and each amendment or
supplement thereto and any documents incorporated by reference therein as such Persons may reasonably request; and, subject to the last paragraph of this Section 5, the Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the 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 

  
 -13- 

 
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. 
 (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 consummation of the offering that is the subject 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, which CUSIP number the Company shall use commercially reasonable efforts to ensure is the same as the CUSIP number for the exchange
notes issued by the Issuers in exchange for the Existing Securities. 

  
 -14- 

 (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 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 the 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 (the Initial Purchaser or any such Holders, Participating Broker-Dealers, 

  
 -15- 

 
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 or any series of capital stock of the Company, including the Company’s common stock, par value $0.0001 per share, 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. 

(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 continue 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 remain 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 continue 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 

  
 -16- 

 
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, 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 that the Exchange Securities (and the related Guarantees) 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 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 (and the related Guarantees), 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 (and the related Guarantees); 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 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. 

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, 

  
 -17- 

 
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

  
 -18- 

 
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 Securities 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 the Initial Purchaser or any Holder furnished to the
Company in writing through the Initial Purchaser 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 under this Section 7(a) 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 Securities 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 Securities 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 

  
 -20- 

 
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. 
 (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 

  
 -21- 

 
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 and following a written request therefor. 

(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

  
 -22- 

 
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 Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (e), each person, if any, who controls a Participant within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act shall have the same rights to contribution as the Participants, and each director of the Company 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 Securities 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 it 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. 

  
 -23- 

 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. 
 (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.

 Exhibit 4.4 

THIRD SUPPLEMENTAL INDENTURE 

THIS THIRD SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of November 19, 2014, is by and among Terra
Fluid Management, LLC, a Delaware limited liability company (“Terra Fluid”), Great Lakes Environmental & Infrastructure Solutions, LLC, a Delaware limited liability company (“GLEIS, LLC”), and Magnus
Pacific Corporation, a California corporation (“Magnus”, and together with Terra Fluid and GLEIS, LLC, the “New Guarantors”), each a subsidiary of Great Lakes Dredge & Dock Corporation, as issuer (the
“Company”), the Company, the existing Guarantors and and Wells Fargo Bank, National Association, as trustee. 
 WITNESSETH

 WHEREAS, the Company and the existing Guarantors have heretofore executed and delivered to the Trustee an indenture (as amended,
supplemented or otherwise modified, the “Indenture”), dated as of January 28, 2011, providing for the issuance of 7.375% Senior Notes due 2019 (the “Notes”); 

WHEREAS, Section 4.15 of the Indenture provides that under certain circumstances the New Guarantors shall execute and deliver to the
Trustee a supplemental indenture pursuant to which the New Guarantors shall unconditionally guarantee all of the obligations of the Company under the Notes and the Indenture on the terms and conditions set forth herein (the
“Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee, the Guarantors and the Company
are authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the New Guarantors, the Company and the Trustee mutually covenant and agree for the equal and ratable benefit of each other and the Holders of the Notes as follows: 

1. Defined Terms. Defined terms used herein without definition shall have the meanings assigned to them in the Indenture. 

2. Agreement to Guarantee. Each of the New Guarantors hereby agrees, jointly and severally with all existing Guarantors (if any), to
provide an unconditional Guarantee on the terms and subject to the conditions set forth in Article 10 of the Indenture and to be bound by all other applicable provisions of the Indenture and the Notes and to perform all of the obligations and
agreements of a Guarantor under the Indenture. 
 3. No Recourse Against Others. No past, present or future director, manager,
officer, employee, incorporator, stockholder or member of the Company, any Guarantor, any parent entity of the Company or any Subsidiary thereof, as such, shall have any liability for any obligations of the Company or the Guarantors under the Notes,
the Indenture, the Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. The waiver and release may not be effective to waive liabilities under the federal securities laws. 

4. Notices. All notices or other communications to the New Guarantors shall be given as provided in Section 12.02 of the Indenture.

 5. Ratification of Indenture; Supplemental Indentures Part of Indenture. Except as

 6. GOVERNING LAW.
THIS SUPPLEMENTAL INDENTURE, THE NOTES AND THE GUARANTEES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. 

7. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but
all of them together represent the same agreement. The exchange of copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to
the parties hereto and may be used in lieu of the original Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes. 

8. Effect of Headings. The section headings herein are for convenience only and shall not affect the construction hereof. 

9. Trustee Makes No Representation. The Trustee makes no representation as to the validity or sufficiency of this Supplemental
Indenture.
