                 CONVERTIBLE SUBORDINATED PROMISSORY NOTE
                 ----------------------------------------

$2,525,000 - Principal Amount	               Issue Date - December 2, 2003

     FOR VALUE RECEIVED, Crdentia Corp., a Delaware corporation ("Obligor"),
hereby promises to pay jointly to the order of Professional Staffing
Resources, Inc., a Georgia corporation and Nursing Services Registry of
Savannah, Inc, a Georgia corporation (collectively with any successors or
assigns, "Holder"), in lawful money of the United States at the address of
Holder set forth below, the principal sum of Two Million Five Hundred
Twenty-Five Thousand Dollars ($2,525,000), together with interest thereon
from the date of this Promissory Note (the "Note") on the unpaid principal
balance.  Interest shall accrue at a rate of eight percent (8%) per annum,
simple interest, until paid in full.

     Subject to the conversion provisions set forth herein, unpaid principal
under this Note together with all accrued and unpaid interest shall be paid
to Holder as follows:  (a) Obligor shall pay to Holder interest only accrued
on this Note as of the last day of each month, commencing with the month
ending November 30, 2003 and continuing through the month ending November
30, 2004, within ten (10) business days of the first day of the following
month; and (b) beginning on December 1, 2004 and continuing through November
1, 2012, Obligor shall make a total of ninety six (96) equal, consecutive
monthly payments to Holder consisting of principal and interest amortized
from the period beginning December 1, 2004, which such payments shall be
made within ten (10) business days of the first date of such month.

     This Note may be prepaid, in whole or in part, at any time without
premium or penalty.  All prepayments on this Note shall be applied first to
the payments of the accrued and unpaid interest and then to the reduction
of the principal balance hereof (applied equally among all remaining
principal installments hereunder).

<PAGE>

     The outstanding principal balance (plus accrued and unpaid interest on
the date thereon) on this Note shall be converted at Holder's option and in
Holder's sole discretion into shares of Obligor's Common Stock (the "Common
Stock") upon delivery of written notice by Holder to Obligor.  The number of
shares of Common Stock shall be equal to the quotient obtained by dividing
(a) the aggregate outstanding principal due, plus accrued and unpaid interest
on this Note on the date of conversion by (b) the Conversion Price.  For
purposes of this Note, the "Conversion Price" shall mean the closing price
of the Common Stock as reported on the National Association of Securities
Dealers, Inc. Over the Counter Bulletin Board (the "OTCBB") or other
national stock exchange on the date of such conversion.  Notwithstanding the
foregoing, in the event that Obligor's Common Stock is not traded on the
OTCBB or other national stock exchange on the date of such conversion, the
"Conversion Price" shall be the fair market value of Obligor's Common Stock
as determined in good faith by Obligor's board of directors, which
Conversion Price so determined shall be delivered in writing to Holder, who
shall have 10 business days after receipt thereof to withdraw the notice of
conversion.  In the event of any such withdrawal, the notice of conversion
shall be void ab initio.

     No fractional shares will be issued upon conversion of this Note.  In
lieu of any fractional share to which Holder would otherwise be entitled,
Obligor will pay to Holder in cash that amount of the unconverted principal
and interest balance of this Note.  Upon conversion of this Note into such
equity securities, Holder shall surrender this Note, duly endorsed, at the
principal offices of Obligor or any transfer agent for Obligor.  At its
expense, Obligor will, as soon as practicable thereafter, issue and deliver
to Holder a certificate for the number of shares of equity securities to
which Holder is entitled upon such conversion, together with any other
securities and property to which Holder is entitled upon such conversion
under the terms of this Note, including a check payable to Holder for any
cash amounts payable as described above.  Upon conversion of this Note into
such equity securities, Obligor will be forever released from all its
obligations and liabilities under this Note, including without limitation
the obligation to pay the principal and interest amounts.

     If any payment of principal or interest on this Note shall become due
on a Saturday, Sunday, or a public holiday under the laws of the State of
California, such payment shall be made on the next succeeding business day.

     The indebtedness evidenced by this Note is hereby expressly
subordinated, to the extent and in the manner hereinafter set forth, in
right of payment to the prior payment in full of all Obligor's Senior Debt.
For purposes of this Note, "Senior Debt" shall mean, except as otherwise
provided herein:  (a) any indebtedness of Obligor (plus interest, premium
and penalties due from or arising out of such indebtedness, or any
refinancing thereof): (i) for borrowed funds; (ii) due to the sellers or
lessors of any real or personal property to Obligor; or (iii) for
reimbursement obligations with respect to letters of credit; (b) any other
indebtedness of Obligor, except to the extent that the holder of such
indebtedness otherwise agrees in writing; and (c) any debentures, notes or
other evidences of indebtedness issued in exchange for any of the foregoing
indebtedness, or any indebtedness arising from the satisfaction of such
indebtedness by a guarantor.  Notwithstanding anything herein to the
contrary, Senior Debt shall not include any indebtedness of Obligor (or of
any subsidiary of Obligor ) incurred as seller financing in connection with
acquisitions of temporary nurses staffing companies or travel nurse
companies consummated prior to or following the date hereof.
Notwithstanding anything herein to the

<PAGE>

contrary, no payment of principal or interest shall be made on this Note if,
but only as long as, there exists any default, or the existence of any
event which, with the giving of notice, would constitute a default, in the
payment of Senior Debt, as determined by the terms of any such Senior Debt.
Holder shall execute, at or following the date hereof, as the case may be,
all subordination documents required by the holders of Senior Debt necessary
to effectuate the terms of the foregoing.

     In the event that Obligor (a) fails to make payment on any date for
payment herein above specified of any principal and/or interest due
hereunder on such date, (b) admits in writing its inability to pay its
debts as they become due, or makes a general assignment for the benefit of
creditors or files any petition or action for relief under any bankruptcy,
reorganization, insolvency or moratorium law, or any other law or laws for
the relief of, or relating to, debtors or (c) an involuntary petition is
filed against Obligor under any bankruptcy, reorganization, insolvency or
moratorium law, or any other law or laws for the relief of, or relating to,
debtors unless such petition shall be dismissed or vacated within sixty (60)
days of the date thereof, Obligor shall be deemed to be in default
hereunder.  In the event of such default, Holder may, at Holder's option
and in Holder's sole discretion, ten (10) business days after giving notice
of default to Obligor, accelerate the maturity of all amounts due under
this Note by giving notice of such acceleration.

     The acceptance by Holder of any payment hereunder which is less than
the payment in full of all amounts due and payable at the time of such
payment shall not constitute a waiver of the right to accelerate at that
time or any subsequent time or nullify any prior acceleration without the
express consent of Holder except as and to the extent otherwise provided by
law.

     Obligor waives presentment, demand for performance, notice of
nonperformance, protest, notice of protest, and notice of dishonor (but not
notice of default).  No delay on the part of Holder in exercising any right
hereunder shall operate as a waiver of such right under this Note.  This
Note is being delivered in and shall be construed in accordance with the
laws of the State of California as applied to contracts entered into by
California residents within the State of California, which contracts are to
be performed entirely within the State of California.

     The right to plead any and all statutes of limitations as a defense to
any demand on this Note, or any guaranty hereof, or any agreement to the
same, or any instrument securing this Note, or any and all obligations or
liabilities arising out of or in connection with this Note, is expressly
waived by Obligor and each and every endorser or guarantor if any, to the
fullest extent permitted by law.

     Notwithstanding anything to the contrary contained herein, the total
liability for payments hereunder in the nature of interest shall not exceed
the limits imposed by applicable interest rate limitation laws.

     The provisions of this Note are intended by Obligor to be severable and
divisible and the invalidity or unenforceability of a provision or term
herein shall not invalidate or render unenforceable the remainder of this
Note or any part thereof.

<PAGE>

     If the indebtedness represented by this Note or any part thereof is
collected at law or in equity or in bankruptcy, receivership or other
judicial proceedings or if this Note is placed in the hands of attorneys
for collection after default, Obligor agrees to pay, in addition to the
principal and interest payable hereon, reasonable attorneys' fees and costs
incurred by Holder.

     Any notice or other communication (except payment) required or
permitted hereunder shall be in writing and shall be deemed to have been
given upon delivery if personally delivered or one day after deposit if
deposited in the United States mail for mailing by certified mail, postage
prepaid, and addressed as follows:
