 NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the sufficiency
and adequacy of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 ARTICLE I 

DEFINITIONS AND INCORPORATION BY REFERENCE 

Section 1.01. Definitions. 

(a) The Base Indenture, as amended and supplemented by the Second Supplemental Indenture and the Third Supplemental Indenture is collectively
referred to herein as the “Indenture.” 
 (b) All capitalized terms used herein and not otherwise defined below shall have
the meanings ascribed thereto in the Indenture. 
 ARTICLE II 

APPLICATION OF SUPPLEMENTAL INDENTURE 

Section 2.01. Application of this Fourth Supplemental Indenture. Notwithstanding any other provision of this Fourth Supplemental
Indenture, the provisions of this Fourth Supplemental Indenture expressly and solely relate to the Indenture with respect to the 2025 Notes and any such provisions shall not be deemed to apply to any other Securities issued under the Indenture and
shall not be deemed to amend, modify or supplement the Indenture for any purpose other than with respect to the 2025 Notes. 
 ARTICLE III

 WAIVERS 

Section 3.01. Waiver of Specified Defaults. The following defaults are hereby irrevocably waived (collectively, the
“Specified Defaults”): 
  

	 	(i)	The failure of the Company to cause Seaspan Investments III, LLC, a limited liability company duly formed under the laws of the Republic of The Marshall Islands to execute (A) a supplemental indenture to become a
Guarantor and guarantee the Indenture Obligations and (B) a joinder to the Registration Rights Agreement, in each case, as required under Section 5.08(a) of the Second Supplemental Indenture; and 


 

	 	(ii)	The failure of the Company to mail a notice of the defaults described in clause (i) above, within 10 Business Days of the discovery thereof as required under Section 5.10 of the Second Supplemental Indenture.


 Section 3.02. Waiver of Specified Covenants. For so long as an entity listed in Schedule I attached hereto
(each a “Specified Entity” and, collectively, the “Specified Entities”) is unable to provide a Guarantee due to a contractual obligation applicable to such Specified Entity as in effect as of March 13, 2018
(such contractual obligation an “Existing Obligation”), any requirement that such Specified Entity execute a supplemental indenture pursuant to which such entity would become a Guarantor and execute a joinder to the Registration
Rights Agreement, is hereby irrevocably waived (the “Specified Covenants”) (and to the extent that a Default has arisen from the failure of any such entity to execute such a supplemental indenture or joinder prior to the execution
of this Fourth Supplemental Indenture that gives effect to such a waiver, such Default is also hereby irrevocably waived). 







 ARTICLE IV 

COVENANTS 

Section 4.01. Guarantee of and Pledge by Seaspan Investment. No later than 12 Business Days after acquiring all the direct and
indirect interests in those entities listed in Schedule I attached hereto, the Company shall cause Seaspan Investment I Ltd. (“Seaspan Investment”) to (i) execute (A) a supplemental indenture pursuant to which Seaspan
Investment shall become a Guarantor and guarantee the Indenture Obligations and (B) a joinder to the Registration Rights Agreement and (ii) pledge, assign and grant to the Trustee for the benefit of the Trustee and the Holders, a lien on
and security interest in and to all of the right, title and interest of Seaspan Investment in the membership interests of Greater China Intermodal Investments LLC, a limited liability company duly organized and existing under the laws of the
Republic of The Marshall Islands pursuant to a pledge agreement in form and substance substantially similar to the Pledge Agreement to secure the Guarantee of Seaspan Investment. 

Section 4.02. Guarantees of Specified Entities. If at any time a Specified Entity is able to provide a Guarantee
without breaching an Existing Obligation, then the Company shall cause such Specified Entity to promptly (but in any event not later than 10 Business Days following the date on which such Existing Obligation ceases to be in effect) execute a
supplemental indenture pursuant to which such Specified Entity shall become a Guarantor and execute a joinder to the Registration Rights Agreement. The future Guarantee by such Specified Entity shall be limited to an amount not to exceed the
maximum amount that can be guaranteed by that Specified Entity without rendering the Guarantee, as it relates to such Specified Entity, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting
the rights of creditors generally. 
 ARTICLE V

Supplemental Indenture are in all respects ratified and confirmed and the Base Indenture, the Second Supplemental, the Third Supplemental Indenture and this Fourth Supplemental Indenture shall be read, taken and constructed as one and the same
instrument.

full amount of the Required Currency expressed to be payable in respect of such payments, (b) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by
which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (c) shall not be affected by judgment being obtained for any other sum due under the Indenture. For purposes of the foregoing,

Company shall bind its successors and assigns, whether so expressed or not.

“pdf” or “tif”) form and the parties hereto adopt any signatures received by facsimile or electronic (i.e., “pdf” or “tif”) transmission as the original signature of such party. This Fourth Supplemental
Indenture shall become effective upon the execution hereof by each of the parties hereto; provided that each waiver set forth in Article III hereof shall become operative as of March 13, 2018 as if this Fourth Supplemental Indenture were
