BOSTON CARRIERS, INC.


 


 


June 9, 2016$3,000,000


  


10.75% CONVERTIBLE PROMISSORY NOTE


 


Boston
Carriers, Inc., a Marshall Islands corporation (the “Company”), for value received, hereby promises to pay
to the order of YP Holdings, LLC, a Texas limited liability company (the “Holder”), the principal sum of three
million Dollars ($3,000,000) (the “Note”).  This Note is issued pursuant to that certain amended
and restated securities purchase agreement of even date herewith, entered into by and between the Company and the Holder (the
“Purchase Agreement”). Defined terms used herein but not otherwise defined shall have the meanings ascribed
thereto in the Purchase Agreement. In the event of a conflict between the terms of this Note and the terms of the Purchase Agreement,
the terms of this Note shall control.


 


1.Payments;
Prepayment.


 


(a)Payments.
This Note is issued on June 9, 2016 (the “Closing Date”). Interest payable on the outstanding principal of
this Note shall accrue from the Closing Date at a rate equal to 10.75% subject to adjustment as provided herein (the “Interest
Rate”) and be computed for actual days elapsed on the basis of a 360 day year consisting of twelve 30-day months. Except
as provided elsewhere in this Section 1, the principal and the Embedded Interest Liability of this Note (collectively, the “Principal”)
shall be payable on or before May 30, 2026 (the “Maturity Date”). On the first business day following the Maturity
Date, sent by overnight courier or registered mail, the Holder shall receive payment of the outstanding Principal. All payments
in respect of the Principal shall be made in cash in U.S. dollars and in immediately available funds. Embedded Interest Liability
means the principal sum of the Note, multiplied by the product of (i) the applicable Interest Rate, and (ii) the number of whole
years between the Closing Date and the Maturity Date.


 


(b)Credit Risk Adjustment.
Notwithstanding any other provision, the Interest Rate shall adjust upward by 98.45 basis points for each amount, if any, equal
to $0.05 (the “Adjustment Factor”), or any portion thereof that the volume weighted average price of the Common
Shares on any Trading Day following the Closing Date (the “Measuring Metric”) is below $0.85 per Common Share
(the “Minimum Triggering Level”). The Interest Rate shall adjust downward by 98.45 basis points for each amount,
if any, equal to the Adjustment Factor that the Measuring Metric is $1.15 per Common Share (the “Maximum
Triggering Level”). 


 


(c)Voluntary
Prepayment. The Principal of this Note may be prepaid by the Company, in whole or in part, without penalty, at any time. Upon
any prepayment of a portion of this Note, a new Note containing the same date and provisions of this Note shall, at the request
of the Holder, be issued by the Company to the Holder for the principal balance of this Note which shall not have been paid.


 






    	 	

	 



    	 



    

2.Original Issue Discount.


 


The Company acknowledges that the principal sum of this Note exceeds the
Subscription Amount and that such excess consists of (a) the Original Issue Discount, and (b) the Transaction Expenses, both
of which shall be fully earned and charged to the Company upon the execution of this Note and paid to the Holder as part of
the outstanding principal balance as set forth in this Note.  


 


3.Conversion
into Common Shares.


 


(a)Voluntary Conversion.
Subject to and upon compliance with the provisions of Sections 3(c) through 3(e) of this Note, at any time while this Note is
outstanding, the Holder shall have the right, at its option, to convert all or a part of the outstanding Principal (including
the Embedded Interest Liability calculated using the applicable adjusted Interest Rate at each Conversion Date), into such number
of Common Shares as is determined by dividing the dollar amount being converted by the applicable Conversion Price. The applicable
“Conversion Price” means 0.70 multiplied by the single lowest closing bid price per Common Share (as reported
by OTC Markets Group Inc. in its “OTCPink” marketplace or, if not reported
in such marketplace, then in any other applicable marketplace of OTC Markets Group Inc.)
on the 20 trading days immediately preceding the applicable Conversion Date.


 


(b)Reduction of Principal.
The Principal due hereunder shall automatically be reduced by the amount of Principal that has previously been converted pursuant
to Section 2(a) hereof. For purposes of the calculation of interest payable on this Note, such reduction of Principal shall be
deemed to have occurred as of the date of such conversion.


 


(c)Conversion Mechanics.
In order to exercise its voluntary conversion rights pursuant to Section 2 of this Note, the Holder shall deliver a written notice
of election to convert sent by overnight courier or registered mail substantially as set forth on Exhibit A hereto
(the “Conversion Notice”) setting forth the amount of Principal the Holder is electing to convert, duly completed
and signed, to the Company. Each conversion shall be deemed to have been effected immediately prior to the close of business on
the first business day following the date that the Conversion Notice is sent to the Company (the “Conversion Date”),
and the Holder shall be deemed to have become the holder of record of the Common Shares at such time and on such date.


 


(d)Delivery of Certificate(s).
As promptly as practicable after delivery by the Holder of the Conversion Notice and in any event within two (2) Business
Days after such delivery, the Company shall issue and deliver to the Holder a certificate or certificates for the number of Common
Shares. In the event that less than the total Principal together with any accrued but unpaid interest thereon remaining under
this Note is converted pursuant to this Section 2, the Company shall, simultaneously with the issuance of certificates for the
Common Shares issuable upon conversion of all or part of this Note, cause the Company to issue and deliver to the Holder (or in
accordance with the instructions of the Holder) a new Note for the balance of the Principal not so converted. All Common Shares
delivered upon conversion of all or part of this Note will upon delivery in accordance with the provisions hereof be duly and
validly issued and fully paid and nonassessable, free of all liens and charges and not subject to any preemptive rights.


 


(e)Fractional Shares.
No fractional Common Shares shall be issued upon conversion of all or part of this Note. Any fractional interest in a Common Share
resulting from conversion of all or part of this Note shall be paid in cash (computed to the nearest cent) equal to such fraction
multiplied by the Conversion Price on the date of such conversion.


 






    	 	

	 



    	 



    

(f)Share Splits. If the Company at any time on or after the Closing
Date subdivides (by any share split, share dividend, recapitalization or otherwise) its outstanding Common Shares into a
greater number of shares, the applicable Adjustment Factor, Maximum Triggering Level, Minimum Triggering Level, and other
share based metrics in effect immediately prior to such subdivision will be proportionately reduced and the number of Common
Shares issuable will be proportionately increased. If the Company at any time on or after such Issuance Date combines (by
combination, reverse share split or otherwise) its outstanding Common Shares into a smaller number of shares, the applicable
Conversion Price, Adjustment Factor, Maximum Triggering Level, Minimum Triggering Level, and other share based metrics in
effect immediately prior to such combination will be proportionately increased and the number of Common Shares will be
proportionately decreased. Any adjustment under this Section shall become effective at the close of business on the date the
subdivision or combination becomes effective.


 


4.Covenants of Company


 


The Company covenants and agrees
that, so long as any principal of this Note shall remain unpaid, unless the Holder shall otherwise consent in writing, it will
comply with the following terms:


 


(a) Compliance with Laws.

extent that noncompliance would not have a material adverse effect upon the business, operations or financial condition of the

(b)Preservation of Existence.
The Company will maintain and preserve, and cause each subsidiary, if any, to maintain and preserve, its existence, and become

(c)Maintenance of Properties.
The Company will maintain and preserve, all of its properties which are necessary in the proper conduct of its business in
good working order and condition, ordinary wear and tear excepted, and comply, at all times with the provisions of all leases
to which it is a party as lessee or under which it occupies property, so as to prevent any forfeiture or material loss thereof
or thereunder.


 


(d)Keeping of Records and
Books of Account. The Company will keep adequate records and books of account, with complete entries made in accordance with

days or any of the actions sought in such proceeding (including, without limitation, the entry of any order for relief against
