AMENDMENT TO BONUS AND OTHER AGREEMENT


 


This Amendment to Bonus and Other Agreement (this “Amendment”) is made
effective as of November 17, 2005 by and among Crdentia Corp., a Delaware
corporation (the “Company”) and James D. Durham (the “Executive”).


 


RECITALS


 


A.                                   The
Company and the Executive are parties to a Bonus and Other Agreement dated December 31,
2003 (the “Agreement”).


 


B.                                     The
Company and the Executive desire to amend certain terms of the Agreement.


 


In consideration of the foregoing and the promises and covenants
contained herein and other good and valuable consideration the receipt of which
is hereby acknowledged, the parties hereto agree as follows.  Any capitalized terms not otherwise defined
herein shall have the meanings given such terms in the Agreement:


 


1.                                       Amendment
to Section 2 of the Agreement.


 


Section 2 of the Agreement shall be amended and restated to read
as follows:


 


“2.                                 The
Executive shall be entitled to receive bonus payments on December 31, 2008
in the amount of $540,000 and on January 4, 2009 in the amount of
$540,000.  The payment of the bonuses
shall not be affected by the termination for any reason (including death or
disability) of the Executive’s employment or service to the Company prior to December 31,
2008 or January 4, 2009.”


 


2.                                       Effect
of Amendment.  Except as expressly
amended, restated or consented to in this Amendment, the Agreement shall
continue in full force and effect.  In
the event of any conflict between the terms of this Amendment and the
Agreement, the terms of this Amendment shall govern and control.


 


3.                                       Governing
Law.  This Amendment shall be
governed by and construed under the laws of the State of Texas as applied to
agreements among Texas residents entered into and to be performed entirely
within Texas.


 


4.                                       Counterparts.  This Amendment may be executed in any number
of counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.


 


5.                                       Severability.  If one or more provisions of this Amendment
are held to be unenforceable under applicable law, such provision shall be
excluded from this Amendment and the balance of the Amendment shall be
interpreted as if such provision were so excluded and shall be enforceable in accordance
with its terms.


 





















 


6.                                       Entire
Agreement.  This Amendment, together
with the Agreement and the documents executed pursuant hereto and thereto,
constitutes the full and entire understanding and agreement between the parties
with regard to the subjects hereof and thereof.
