                    CRDENTIA CORP. 2004 STOCK INCENTIVE PLAN

                          STOCK OPTION AWARD AGREEMENT

      1. Grant of Option. Crdentia Corp., a Delaware corporation (the
"Company"), hereby grants to the Grantee (the "Grantee") named in the Notice of
Stock Option Award (the "Notice"), an option (the "Option") to purchase the
Total Number of Shares of Common Stock subject to the Option (the "Shares") set
forth in the Notice, at the Exercise Price per Share set forth in the Notice
(the "Exercise Price") subject to the terms and provisions of the Notice, this
Stock Option Award Agreement (the "Option Agreement") and the Company's 2004
Stock Incentive Plan, as amended from time to time (the "Plan"), which are
incorporated herein by reference. Unless otherwise defined herein, the terms
defined in the Plan shall have the same defined meanings in this Option
Agreement.

      The Option is intended to qualify as a Non-Qualified Stock Option and not
as an Incentive Stock Option as defined in Section 422 of the Code.

      2. Exercise of Option.

            (a) Right to Exercise. The Option shall be exercisable during its
term in accordance with the Vesting Schedule set out in the Notice and with the
applicable provisions of the Plan and this Option Agreement. The Option shall be
subject to the provisions of Section 11 of the Plan and Section 2(d) of this
Option Agreement relating to the exercisability or termination of the Option in
the event of a Corporate Transaction or Change in Control. The Grantee shall be
subject to reasonable limitations on the number of requested exercises during
any monthly or weekly period as determined by the Administrator. In no event
shall the Company issue fractional Shares.

            (b) Method of Exercise. The Option shall be exercisable by delivery
of an exercise notice (a form of which is attached as Exhibit A) or by such
other procedure as specified from time to time by the Administrator which shall
state the election to exercise the Option, the whole number of Shares in respect
of which the Option is being exercised, and such other provisions as may be
required by the Administrator. The exercise notice shall be delivered in person,
by certified mail, or by such other method (including electronic transmission)
as determined from time to time by the Administrator to the Company accompanied
by payment of the Exercise Price. The Option shall be deemed to be exercised
upon receipt by the Company of such notice accompanied by the Exercise Price,
which, to the extent selected, shall be deemed to be satisfied by use of the
broker-dealer sale and remittance procedure to pay the Exercise Price provided
in Section 3(d), below.

            (c) Taxes. No Shares will be delivered to the Grantee or other
person pursuant to the exercise of the Option until the Grantee or other person
has made arrangements acceptable to the Administrator for the satisfaction of
applicable income tax and employment tax withholding obligations, including,
without limitation, such other tax obligations of the Grantee incident to the
receipt of Shares. Upon exercise of the Option, the Company or the Grantee's
employer may offset or withhold (from any amount owed by the Company or the
Grantee's employer to the Grantee) or collect from the Grantee or other person
an amount sufficient to satisfy such tax withholding obligations.

                                       1
<PAGE>

      (d) Acceleration of Option Upon Corporate Transaction or Change in
Control.

            (i) Corporate Transaction. In the event of a Corporate Transaction
and irrespective of whether the Option is Assumed or Replaced, the Option
automatically shall become fully vested and exercisable immediately prior to the
specified effective date of such Corporate Transaction, for all of the Shares at
the time represented by the Option, provided that the Grantee's Continuous
Service has not terminated prior to such date.

            (ii) Change in Control. In the event of a Change in Control (other
than a Change in Control which also is a Corporate Transaction), the Option
shall become fully vested and exercisable immediately prior to the specified
effective date of such Change in Control, for all of the Shares at the time
represented by the Option, provided that the Grantee's Continuous Service has
not terminated prior to such date.

      3. Method of Payment. Payment of the Exercise Price shall be made by any
of the following, or a combination thereof, at the election of the Grantee;
provided, however, that such exercise method does not then violate any
Applicable Law and, provided further, that the portion of the Exercise Price
equal to the par value of the Shares must be paid in cash or other legal
consideration permitted by the Delaware General Corporation Law:

            (a) cash;

            (b) check;

            (c) surrender of Shares or delivery of a properly executed form of
attestation of ownership of Shares as the Administrator may require which have a
Fair Market Value on the date of surrender or attestation equal to the aggregate
Exercise Price of the Shares as to which the Option is being exercised,
provided, however, that Shares acquired under the Plan or any other equity
compensation plan or agreement of the Company must have been held by the Grantee
for a period of more than six (6) months (and not used for another Award
exercise by attestation during such period); or

            (d) payment through a broker-dealer sale and remittance procedure
pursuant to which the Grantee (i) shall provide written instructions to a
Company-designated brokerage firm to effect the immediate sale of some or all of
the purchased Shares and remit to the Company sufficient funds to cover the
aggregate exercise price payable for the purchased Shares and (ii) shall provide
written directives to the Company to deliver the certificates for the purchased
Shares directly to such brokerage firm in order to complete the sale
transaction.

      4. Restrictions on Exercise. The Option may not be exercised if the
issuance of the Shares subject to the Option upon such exercise would constitute
a violation of any Applicable Laws. If the exercise of the Option within the
applicable time periods set forth in Section 6, 7 and 8 of this Option Agreement
is prevented by the provisions of this Section 5, the Option shall remain
exercisable until one (1) month after the date the Grantee is notified by the
Company that the Option is exercisable, but in any event no later than the
Expiration Date set forth in the Notice.

                                       2
<PAGE>

      5. Termination or Change of Continuous Service. In the event the Grantee's
Continuous Service terminates, the Grantee may, but only during the
Post-Termination Exercise Period, exercise the portion of the Option that was
vested at the date of such termination (the "Termination Date"). The
Post-Termination Exercise Period shall commence on the Termination Date. In no
event, however, shall the Option be exercised later than the Expiration Date set
forth in the Notice. In the event of the Grantee's change in status from
Employee, Director or Consultant to any other status of Employee, Director or
Consultant, the Option shall remain in effect and vesting of the Option shall
continue only to the extent determined by the Administrator as of such change in
status. Except as provided in Sections 6 and 7 below, to the extent that the
Option was unvested on the Termination Date, or if the Grantee does not exercise
the vested portion of the Option within the Post-Termination Exercise Period,
the Option shall terminate.

      6. Disability of Grantee. In the event the Grantee's Continuous Service
terminates as a result of his or her Disability, the Grantee may, but only
within twelve (12) months commencing on the Termination Date (but in no event
later than the Expiration Date), exercise the portion of the Option that was
vested on the Termination Date. To the extent that the Option was unvested on
the Termination Date, or if the Grantee does not exercise the vested portion of
the Option within the time specified herein, the Option shall terminate.

      7. Death of Grantee. In the event of the termination of the Grantee's
Continuous Service as a result of his or her death, or in the event of the
Grantee's death during the Post-Termination Exercise Period or during the twelve
(12) month period following the Grantee's termination of Continuous Service as a
result of his or her Disability, the person who acquired the right to exercise
the Option pursuant to Section 8 may exercise the portion of the Option that was
vested at the date of termination within twelve (12) months commencing on the
date of death (but in no event later than the Expiration Date). To the extent
that the Option was unvested on the date of death, or if the vested portion of
the Option is not exercised within the time specified herein, the Option shall
terminate.

      8. Transferability of Option. The Option may not be transferred in any
manner other than by will or by the laws of descent and distribution, provided,
however, that the Option may be transferred during the lifetime of the Grantee
to the extent and in the manner authorized by the Administrator. Notwithstanding
the foregoing, the Grantee may designate one or more beneficiaries of the
Grantee's Option in the event of the Grantee's death on a beneficiary
designation form provided by the Administrator. Following the death of the
Grantee, the Option, to the extent provided in Section 7, may be exercised (a)
by the person or persons designated under the deceased Grantee's beneficiary
designation or (b) in the absence of an effectively designated beneficiary, by
the Grantee's legal representative or by any person empowered to do so under the
deceased Grantee's will or under the then applicable laws of descent and
distribution. The terms of the Option shall be binding upon the executors,
administrators, heirs, successors and transferees of the Grantee.

                                       3
<PAGE>

      9. Term of Option. The Option must be exercised no later than the
Expiration Date set forth in the Notice or such earlier date as otherwise
provided herein. After the Expiration Date or such earlier date, the Option
shall be of no further force or effect and may not be exercised.

      10. Tax Consequences. Set forth below is a brief summary as of the date of
this Option Agreement of some of the federal tax consequences of exercise of the
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE,
AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. THE GRANTEE SHOULD
CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION OR DISPOSING OF THE SHARES.

            (a) Exercise of Non-Qualified Stock Option. On exercise of a
Non-Qualified Stock Option, the Grantee will be treated as having received
compensation income (taxable at ordinary income tax rates) equal to the excess,
if any, of the Fair Market Value of the Shares on the date of exercise over the
Exercise Price. If the Grantee is an Employee or a former Employee, the Company
will be required to withhold from the Grantee's compensation or collect from the
Grantee and pay to the applicable taxing authorities an amount in cash equal to
a percentage of this compensation income at the time of exercise, and may refuse
to honor the exercise and refuse to deliver Shares if such withholding amounts
are not delivered at the time of exercise.

            (b) Disposition of Shares. In the case of a Non-Qualified Stock
Option, if Shares are held for more than one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
income tax purposes.

      11. Entire Agreement: Governing Law. The Notice, the Plan and this Option
Agreement constitute the entire agreement of the parties with respect to the
subject matter hereof and supersede in their entirety all prior undertakings and
agreements of the Company and the Grantee with respect to the subject matter
hereof, and may not be modified adversely to the Grantee's interest except by
means of a writing signed by the Company and the Grantee. Nothing in the Notice,
the Plan and this Option Agreement (except as expressly provided therein) is
intended to confer any rights or remedies on any persons other than the parties.
The Notice, the Plan and this Option Agreement are to be construed in accordance
with and governed by the internal laws of the State of Texas without giving
effect to any choice of law rule that would cause the application of the laws of
any jurisdiction other than the internal laws of the State of Texas to the
rights and duties of the parties. Should any provision of the Notice, the Plan
or this Option Agreement be determined to be illegal or unenforceable, such
provision shall be enforced to the fullest extent allowed by law and the other
provisions shall nevertheless remain effective and shall remain enforceable.

      12. Construction. The captions used in the Notice and this Option
Agreement are inserted for convenience and shall not be deemed a part of the
Option for construction or interpretation. Except when otherwise indicated by
the context, the singular shall include the plural and the plural shall include
the singular. Use of the term "or" is not intended to be exclusive, unless the
context clearly requires otherwise.

                                       4
<PAGE>

      13. Administration and Interpretation. Any question or dispute regarding
the administration or interpretation of the Notice, the Plan or this Option
Agreement shall be submitted by the Grantee or by the Company to the
Administrator. The resolution of such question or dispute by the Administrator
shall be final and binding on all persons.

      14. Venue and Waiver of Jury Trial. The Company, the Grantee, and the
Grantee's assignees pursuant to Section 8 (the "parties") agree that any suit,
action, or proceeding arising out of or relating to the Notice, the Plan or this
Option Agreement shall be brought in the United States District Court for the
Northern District of Texas (or should such court lack jurisdiction to hear such
action, suit or proceeding, in a Texas state court in the County of Dallas) and
that the parties shall submit to the jurisdiction of such court. The parties
irrevocably waive, to the fullest extent permitted by law, any objection the
party may have to the laying of venue for any such suit, action or proceeding
brought in such court. THE PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR
MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one or
more provisions of this Section 14 shall for any reason be held invalid or
unenforceable, it is the specific intent of the parties that such provisions
shall be modified to the minimum extent necessary to make it or its application
valid and enforceable.

      15. Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery, upon
deposit for delivery by an internationally recognized express mail courier
service or upon deposit in the United States mail by certified mail (if the
parties are within the United States), with postage and fees prepaid, addressed
to the other party at its address as shown in these instruments, or to such
other address as such party may designate in writing from time to time to the
other party.
