	$__________    	 	Cambridge, Massachusetts 
	 	 	Date: ___________ 


 


For value received, the
undersigned, Pathfinder Cell Therapy, Inc., a Delaware corporation (the “ Borrower ”), hereby unconditionally
promises to pay to the order of _____________ (the “ Payee ”), the principal sum of $_______   and 00/100   Dollars ($_________ ),
together with interest to maturity (whether by lapse of time, acceleration or otherwise) on the balance of principal
remaining from time to time outstanding at a rate per annum equal to 6%. Interest shall be calculated on the basis of a
360-day year and actual days.


 


The outstanding principal amount, together with accrued interest,
of this Promissory Note shall become due and payable on the first anniversary of the date hereof.


 


Payee may elect, at any time prior to completion or termination
of the Capital Raise (defined below), upon written notice to Borrower, to convert all or a portion of the outstanding principal
and/or interest hereof, to shares of common stock of the Borrower, for the subscription price thereof, in the Capital Raise.  “Capital
Raise” has the meaning used in that certain agreement and plan of merger dated December 22, 2010 (as amended) by and among
Borrower, a wholly-owned subsidiary of Borrower, and Pathfinder, LLC, a Massachusetts limited liability company, pursuant to which
Borrower acquired Pathfinder, LLC in a merger transaction, the initial closing of which Capital Raise occurred in September 2011
immediately after the merger. As a condition to any such conversion, Payee shall execute and deliver to Borrower such agreements
and documentation as Borrower requires of other investors in the Capital Raise.


 


The Borrower shall have the right to prepay, at any time,
all or any portion of the principal indebtedness evidenced by this Note, together with any accrued interest.


 


No failure by the holder of this Note to exercise, and no
delay in exercising, any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise by
such holder of any right or power preclude any other or further exercise thereof or the exercise of any other right or power.  The
rights and remedies of the holder hereof as herein specified are cumulative and not exclusive of any other rights or remedies which
such holder may otherwise have.


 


The undersigned agrees to pay all costs and expenses incurred
by the holder hereof in enforcing this Note, including, without limitation, reasonable attorneys’ fees and disbursements.

or secondarily liable on this Note, or of any collateral securing this Note, shall operate to discharge the indebtedness evidenced
by this Note.  If this Note is signed by more than one person, all references to the Borrower shall apply to each of
them and their liabilities hereunder shall be joint and several.


 


Any notice of non-payment shall be deemed given when delivered
in hand or when mailed, postage prepaid, by certified or registered mail, return receipt requested to the Borrower at 12 Bow Street,
Cambridge, Massachusetts 02138 or sent thereto by Federal Express or comparable overnight courier.
