                                STATE OF DELAWARE
                            CERTIFICATE OF CORRECTION

Crdentia Corp., a corporation organized and existing under and by virtue of the
General Corporation Law of the State of Delaware.

DOES HEREBY CERTIFY:

1. The name of the corporation is Crdentia Corp.

2. That a Certificate of Designations, Preferences and Rights of Series B-1
Preferred Stock of the corporation was filed by the Secretary of State of
Delaware on August 9, 2004 and that said Certificate requires correction as
permitted by Section 103 of the General Corporation Law of the State of
Delaware.

3. The inaccuracy or defect of said Certificate to be corrected is as follows:

Each holder of a share of Series B-1 Preferred Stock shall be entitled to
receive a dividend of 2.5 shares of Common Stock, rather than a dividend of 1.5
shares of Common Stock, on each of September 30, 2004, December 31, 2004, March
31, 2005, June 30, 2005, September 30, 2005 and December 31, 2005.

4. Section 2 of the Certificate is corrected to read as follows:

"Section 2. DIVIDENDS AND DISTRIBUTIONS. Subject to the rights of the holders of
any shares of any series of Preferred Stock (or any similar stock) expressly
ranking senior to, or PARI PASSU with, the Series B-1 Preferred Stock with
respect to dividends, each holder of a share of Series B-1 Preferred Stock, in
preference to the holders of shares of Common Stock, par value $0.0001 per share
(the "COMMON STOCK"), of the Corporation, and of any other junior stock, shall
be entitled to receive, when declared by the Board of Directors out of funds
legally available for the purpose, a dividend of 2.5 shares of Common Stock
(subject to adjustment as described below) on each of September 30, 2004,
December 31, 2004, March 31, 2005, June 30, 2005, September 30, 2005 and
December 31, 2005 (each, a "DESIGNATED DIVIDEND Date"). In the event of an
automatic conversion of the Series B-1 Preferred Stock pursuant to Section 4(b)
below prior to the next scheduled Designated Dividend Date, if any, the Company
shall immediately prior to such automatic conversion pay a dividend on each
share of Series B-1 Preferred Stock of 2.5 shares of Common Stock (subject to
adjustment as described below). In addition, if any cash dividend is declared on
shares of Common Stock, a dividend shall be paid out of legally available funds
on each share of Series B-1 Preferred Stock equal to the consideration that each
such share would have received had such share been converted into Common Stock
immediately prior to the record date fixed for such dividend. The dividend of
2.5 shares of Common Stock described herein shall be (i) increased or decreased
in proportion to the increase or decrease in the Conversion Ratio (as defined in
Section 4(a)) effected pursuant to Sections 4(d)(iii) or (iv) and (ii) adjusted
for stock splits, dividends, recapitalizations and the like of the Series B-1
Preferred Stock."
