any authorized extension or modification thereof. Further, it is expressly understood and declared that all monies due and to become due under any contracts covered by the Bonds are trust funds, whether in the possession of any Contractor or
Indemnitor or otherwise, for the benefit of and for payment of all such obligations in connection with any such contract or contracts for which the Surety would be liable under any Bonds, which trust also inures to the benefit of the Surety for any
liability or Loss Surety may have or sustain under any Bonds, and this Agreement and declaration shall also constitute notice of such trust.

loans, to advance or lend to any Contractor any money, which the Surety may see fit, for the purpose of any contracts referred to in, or guaranteed by the Bonds. Contractors and Indemnitors shall be responsible for indemnifying Surety for all money

 BOOKS AND RECORDS 

NINTH: At any time, and until such time as the liability of the Surety under any and all Bonds is terminated, the Surety shall have the
right to reasonable access to the books, records, and accounts of the Contractors and Indemnitors. Contractors and Indemnitors hereby authorize any bank depository, materialman, supply house, or other person, firm, or corporation, when requested by
the Surety, to furnish the Surety any information requested, including but not limited to the status of the work under contracts being performed by any Contractor, the condition of the performance of such contracts, and payments of accounts.

 DECLINE EXECUTION 
 TENTH: Surety may decline to execute any Bond and Contractors and Indemnitors agree to make no claim to the contrary in consideration of the Surety's receiving this Agreement; and if the Surety shall
execute a bid or proposal Bond, it shall have the right to decline to execute any and all Bonds that may be required in connection with any award that may be made under the proposal for which the bid or proposal Bond is given, and such declination
shall not diminish or alter the liability that may arise by reason of having executed the bid or proposal Bond. 
 NOTICE OF
EXECUTION 
 ELEVENTH: Contractors and Indemnitors hereby waive notice of the execution of any and all Bonds and all notice
of any default or any other act or acts giving rise to any claim under said Bonds, as well as notice of any and all liability of the Surety under such Bonds, and any and all liability on their part hereunder, to the end and effect that the
Contractors and Indemnitors shall be and continue liable to Surety under this Agreement, notwithstanding any notice of any kind to which they might have been or be entitled, and notwithstanding any defenses they might have been entitled to make.

 PAYMENTS 
 TWELFTH: In the event the Surety makes any payment or other determination arising from or related to the Bonds and/or this Agreement, or in the event of settlement, compromise or judgment, Contractors and
Indemnitors further agree that in any accounting between the Surety and any Contractor, or between the Surety and the Indemnitors, or either or both of them, the Surety shall be entitled to charge for any and all payments made by the Surety in good
faith under the belief that the Surety is or was liable for the sums and amounts paid, or that it was necessary or expedient to make such payments to protect any of the Surety’s rights or to avoid or lessen the Surety’s liability or
alleged liability, whether or not such liability, necessity or expediency existed; provided, however, that in no event shall any Contractor or Indemnitor indemnify or hold and save harmless the Surety against any Loss arising out of the gross
negligence, willful misconduct or illegal act of the Surety. These payments include the Surety’s costs and expenses and other elements of Loss. Any such payments shall be final, conclusive and binding upon Contractors and Indemnitors; and any
Loss which may be sustained or incurred shall be paid by the Contractors and Indemnitors upon written demand by the Surety. In the event of any payment, settlement, compromise or judgment by the Surety, an itemized statement of Loss sworn to by an
officer or authorized representative of the Surety or voucher(s) or other documentary evidence of such payment, settlement, compromise or judgment shall be prima facie evidence of the fact and amount of Contractors’ and Indemnitors’
liability to the Surety. 
 SETTLEMENTS 
 THIRTEENTH: Surety shall have the absolute and unconditional right to adjust, settle or compromise any claim, demand, suit or judgment upon the Bonds. If Contractors and Indemnitors shall request the
Surety to litigate such claim or demand, or to defend such suit, or to appeal from such judgment, then Contractors and Indemnitors shall deposit with the Surety, at the time of such request, cash or collateral satisfactory to the Surety in kind and
amount, to be used in paying any judgment or judgments rendered or that may be rendered, with interest, costs, expenses and attorneys' fees, including those of the Surety, and the Surety shall consider such request. 

SURETIES 

FOURTEENTH: In the event the Surety procures the execution of the Bonds by other sureties, or executes the Bonds with co-sureties, or
reinsures any portion of the Bonds with reinsuring sureties, or reinsures any Bonds executed by others, then all the terms and conditions of this Agreement shall inure to the benefit of such other sureties, co-sureties and reinsuring sureties, as
their interests may appear. 
 SUITS 
 FIFTEENTH: Separate suits may be brought hereunder as causes of action accrue, and the bringing of suit or the recovery of judgment upon any cause of action shall not prejudice or bar the bringing of
other suits, upon other causes of action, whether theretofore or thereafter arising. 
 OTHER INDEMNITY 

SIXTEENTH: Contractors and Indemnitors shall continue to remain bound under the terms of this Agreement even though the Surety may have
from time to time before or after the execution of this Agreement, with or without notice to or knowledge of Contractors and Indemnitors, accepted or released other agreements of indemnity or collateral in connection with the execution or
procurement of the Bonds, from Contractors or Indemnitors or others, it being expressly understood and agreed by the Contractors 

  

					
	C345 Ed 12 09 modified for GLCC	  	page 3 of 16	  	 









 
and the Indemnitors that any and all other rights which the Surety may have or acquire against the Contractors and the Indemnitors and/or others under any such other or additional agreements of
indemnity or collateral shall be in addition to, and not in lieu of, the rights afforded the Surety under this Agreement. 

INVALIDITY 
 SEVENTEENTH: In case any of the parties mentioned in this Agreement fail to execute the same, or in case the execution hereof by any of the parties be defective or invalid for any reason, such failure,
defect or invalidity shall not in any manner affect the validity of this Agreement or the liability hereunder of any of the parties executing the same, but each and every party so executing shall be and remain fully bound and liable hereunder to the
same extent as if such failure, defect or invalidity had not existed. It is understood and agreed by the Contractors and Indemnitors that the rights, powers, and remedies given the Surety under this Agreement shall be and are in addition to, and not
in lieu of, any and all other rights, powers, and remedies which the Surety may have or acquire against the Contractors and Indemnitors or others whether by the terms of any other agreement or by operation of law or otherwise. 

ATTORNEY IN FACT 
 EIGHTEENTH: Contractors and Indemnitors hereby irrevocably nominate, constitute, appoint and designate Surety as their attorney-in-fact, with the right, but not the obligation, to exercise all of the
rights of Contractors and Indemnitors assigned, transferred and set over to the Surety in this Agreement, and in the name of Contractors and Indemnitors to make, execute, and deliver any and all additional or other assignments, documents or papers
deemed necessary and proper by Surety in order to give full effect not only to the intent and meaning of the assignments in this Agreement, but also to the full protection intended to be given to Surety under all other provisions of this Agreement.
Contractors and Indemnitors hereby ratify and confirm all acts and actions taken and done by the Surety as such attorney-in-fact. 
 TERMINATION 
 NINETEENTH: This Agreement may be
terminated by any Contractor or Indemnitor by sending written notice of termination to the Surety via registered mail to the Surety’s home office at Zurich Surety, Red Brook Corporate Center, 600 Red Brook Blvd., 4th Floor, Owings Mills, Maryland 21117, Attention: Vice President,
Surety Department. Such notice of termination shall be effective as to the party sending the notice, ten (10) days from Surety’s receipt of the notice and shall apply all future Bonds and Bond commitments following the effective date.
However, any such notice of termination shall not operate to modify, bar, or discharge the party sending as to Bonds and Bond commitments that may have been theretofore issued and/or executed, nor shall the notice of termination affect the
obligations of any other party to this Agreement. 
 BONDS FOR OTHER ENTITIES 

TWENTIETH: Contractors and Indemnitors hereby agree that their obligations under this Agreement shall apply to any Bonds the Surety
executes on behalf of any Subsidiaries or Affiliates of Contractors or Indemnitors, and if requested in writing by GREAT LAKES DREDGE & DOCK CORPORATION or GREAT LAKES DREDGE & DOCK COMPANY, LLC, any other legal entities in which
any Contractor or Indemnitor has an ownership interest including, but not limited to, any corporations, partnerships, limited liability companies (LLC) and joint ventures, whether acting alone or in joint venture with others not named in this
Agreement. In addition, the Contractors and Indemnitors agree that their obligations under this Agreement shall apply to any Bonds the Surety issues on behalf of any entity upon the written request of GREAT LAKES DREDGE & DOCK CORPORATION
or GREAT LAKES DREDGE & DOCK COMPANY, LLC. 
 OTHER PROVISIONS 

TWENTY-FIRST: NO ORAL MODIFICATION: This Agreement may not be changed or modified orally. No change or modification shall be effective
unless made by written endorsement executed to form a part hereof. 
 TWENTY-SECOND: PLACE SURETY IN FUNDS: Should an Event of
Default occur, or upon determination by Surety, in its sole and absolute discretion, that potential liability exists under any Bond (regardless of whether liability has been established or whether Surety, Contractors or Indemnitors may have defenses
to all or any portion of any claim asserted under any Bond), Contractors and Indemnitors shall, upon demand, deposit with Surety cash or other collateral acceptable to Surety in an amount determined by Surety, in its sole discretion, to be
sufficient to discharge any claim made against or potential liability of Surety on any Bond or Bonds or under this Agreement. Surety shall not be required to post a reserve prior to or as a condition of Contractors and Indemnitors’ obligation
to deposit collateral. This sum may be used by Surety to pay such claim or be held by Surety as collateral against any loss on any Bond or Bonds or under this Agreement. Any remaining sums deposited with Surety after payment of any and all sums due
to Surety under this Agreement or otherwise shall be returned to Contractors and Indemnitors upon the complete release and/or discharge of Surety’s obligations and liability under all Bonds. The Surety’s demand for collateral shall be
sufficient if sent by registered or certified mail, by facsimile transmission, or by personal service to Contractors and Indemnitors at the addresses stated herein, or at the address last known to the Surety, regardless of whether actually received.


  

					
	C345 Ed 12 09 modified for GLCC	  	page 4 of 16	  	 









 
Contractors and Indemnitors acknowledge that the failure of Contractors and/or Indemnitors, collectively or individually, to deposit collateral with the Surety, immediately upon demand, shall
cause irreparable harm to the Surety for which the Surety has no adequate remedy at law. Contractors and Indemnitors agree that the Surety shall be entitled to injunctive relief for specific performance of the obligation to deposit with the Surety
the sum demanded as collateral and waive any claims or defenses to the contrary. 
 TWENTY-THIRD: Change in Control or
Condition: In the event any Change in Control and/or Change in Condition (both as defined in this paragraph) of any Contractor or Indemnitor occurs without the prior written consent of the Surety, then Contractors and Indemnitors will be deemed to
be in default under the terms of this Agreement and the Surety will have the right to exercise all of its rights and remedies under this Agreement, at law, or in equity. 
 TWENTY-FOURTH: Joint and Several. The agreements and covenants herein contained shall be binding upon the undersigned, both jointly and severally, and upon their successors and assigns jointly and
severally (including successors by way of merger, acquisition or similar event). 
 TWENTY-FIFTH: Contractors and Indemnitors
release, discharge, and waive any and all claims, demands or causes of action arising from or relating to Surety’s exercise of its rights and remedies pursuant to this Agreement. If Surety demands that Indemnitors perform any obligation under
this Agreement including, but not limited to, Contractors’ and/or Indemnitors’ obligation to indemnify or reimburse Surety, to deposit collateral with Surety or to obtain the discharge of Surety under any Bond or Bonds, Contractors’
and Indemnitors’ sole remedy against Surety shall be limited to and capped at the return of any payments made or collateral deposited with Surety pursuant to Surety’s request or demands. Contractors and Indemnitors expressly waive any
claim against Surety for consequential damages, extra-contractual damages and/or attorneys’ fees. 
 TWENTY-SIXTH: This
Agreement may be executed in any number of counterparts with separate signature pages, all of which taken together shall constitute the Agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective as to each Contractor and Indemnitor when each Contractor and/or Indemnitor has executed it. Contractors and Indemnitors hereby acknowledge that the failure of any one of them to execute this Agreement shall not in any
way affect the validity or enforceability of this Agreement as to those Contractors and Indemnitors who have executed the Agreement. 
 TWENTY-SEVENTH: Applicable Law. The terms and conditions of this Agreement shall be construed under the laws of New York without regard to its conflicts of laws principles.
