TO:        HOLDERS OF SERIES B AND SERIES B-1 PREFERRED STOCK OF CRDENTIA CORP.

FROM:      THE BOARD OF DIRECTORS OF CRDENTIA CORP.

DATE:      MARCH 4, 2005

SUBJECT:   CONVERSION OF SERIES B AND SERIES B-1 PREFERRED STOCK
================================================================================

         We are pleased to inform you that, in order to meet immediate working
capital needs, the Board of Directors (the "BOARD") of Crdentia Corp. (the
"COMPANY") has approved additional funding for the Company in the form of a
$6,500,000 Series C Preferred Stock Warrant financing (the "FINANCING") with
MedCap Partners, L.P. ("MEDCAP").

         Under the terms of the Financing, MedCap would exercise warrants to
purchase 108,334 shares of Series C Preferred Stock previously issued to it (the
"WARRANTS"), resulting in proceeds of $6,500,000 to the Company. As discussed in
further detail below, MedCap's exercise of the Warrants pursuant to the
Financing would be subject to the fulfillment of a number of conditions,
including (without limitation) the conversion of all outstanding shares of
Series B and Series B-1 Preferred Stock to Common Stock (such event, the
"CONVERSION"). C. Fred Toney, a member of our Board of Directors, is the
managing member of MedCap. Mr. Toney abstained from voting with respect to the
approval of the Financing by the Board of Directors.

         In connection with this request for the Conversion, the Board of
Directors has called a Special Meeting of the Holders of Series B and Series B-1
Preferred Stock (the "SPECIAL MEETING") to approve the Conversion. The Special
Meeting will be held at the Company's offices at 14114 Dallas Parkway, Suite
600, Dallas, Texas, on Thursday, March 17, 2005 at 9:30 a.m., Central time.

         Through this memorandum, the Company is taking the opportunity to (A)
describe the terms of the Financing, (B) explain why the Board considers the
Financing and associated Conversion to be in the best interests of the Company
and its stockholders, (C) discuss certain risks associated with the Conversion
and (D) explain the matters to be approved at the Special Meeting and what
actions are needed from you in this regard.

(A)      TERMS OF FINANCING

         On or about February 18, 2005, the Company executed a non-binding
letter of intent with MedCap in connection with the Financing pursuant to which
MedCap would exercise currently outstanding Warrants to purchase 108,334 shares
of Series C Preferred Stock at a per share exercise price of $60.00, resulting
in cash proceeds to the Company of approximately $6,500,000. Following such
exercise, such shares of Series C Preferred Stock will represent approximately
17.6% of the Company on a fully-diluted basis. The terms of the Financing are
set forth in the Summary of Terms attached hereto as Exhibit A (the "SUMMARY OF
TERMS") and will be subject to the negotiation and execution of definitive
transaction documents with MedCap.




         As described previously, there are a number of conditions to MedCap's
obligation to exercise the Warrants in connection with the Financing, the most
critical of which is the agreement of a majority of the holders of each of the
Series B and Series B-1 Preferred Stock to convert to Common Stock. Pursuant to
the terms of Section 4(b) of the Certificate of Designations, Preferences and
Rights ("CERTIFICATE OF DESIGNATIONS") of each of the Series B and Series B-1
Preferred Stock, each share of Series B and Series B-1 Preferred Stock may be
automatically converted to Common Stock upon the date specified by the written
consent or agreement of the holders of a majority of the then outstanding shares
of each of the Series B Preferred Stock or Series B-1 Preferred Stock,
respectively, voting as a respective class. To that end, as indicated above and
in Section C below, the Board of Directors has called the Special Meeting for
the holders of each of the Series B and Series B-1 Preferred Stock to approve
the Conversion.

         In partial consideration for the Conversion (and contingent upon and
subject to the Conversion and the consummation of the Financing), the Company
will file a registration statement with the Securities and Exchange Commission
(the "SEC") under the Securities Act of 1933, as amended (the "ACT") on either
Form S-2 or Form S-3 (to the extent that the Company is then eligible to use
such forms) no later than nine months following the closing of the Financing to
register the resale of the shares issued on conversion of the Series B and
Series B-1 Preferred Stock. Such registration rights will otherwise be governed
by the Registration Rights Agreement previously executed by and among the
Company and such holders, as applicable.

         In addition to the Conversion, there are other conditions to MedCap's
obligations to exercise the Warrants in connection with the Financing. As set
forth in the Summary of Terms, the Company will be obligated (concurrent with
the closing of the Financing) to close or have closed two targeted acquisitions
on terms approved by MedCap. The Company will also agree to file a registration
statement with the SEC under the Act to register the resale of the shares of
Common Stock issuable upon exercise of all outstanding shares of Series C
Preferred Stock (including those issued under the Warrants), as well as all
additional shares (and warrants to purchase shares) of capital stock held by
MedCap and its affiliates, which will represent approximately 55.6% of the
outstanding Common Stock of the Company, as calculated on a fully-diluted basis.

         As part of the Financing, the Company will also repay outstanding
indebtedness of approximately $1,450,000 in principal, plus accrued interest,
owed to MedCap. In consideration for MedCap's having extended the maturity date
of the indebtedness through the closing of the Financing, the Company will issue
MedCap $162,500 worth of shares of Common Stock at a per share price equal to
the market value of such shares at the time of the closing of the Financing. In
addition, the Company will secure continued lending from Bridge Healthcare
Finance ("BRIDGE HEALTHCARE") under an existing revolving credit facility, such
that the accounts receivable related to the acquisitions, contemplated to be
closed in connection with the Financing, will be financed by Bridge Healthcare
and an interest rate reset (lowering the current interest rate) will be
triggered at July 1, 2005 under existing agreements. The Company has also agreed
that, at the closing of the Financing, the Company shall have constituted its
Audit Committee with three members, including a "financial expert".




         As indicated, the foregoing are conditions to MedCap's obligation to
exercise the Warrants in connection with the Financing, any or all of which
conditions MedCap may waive in its sole discretion in determining whether or not
to proceed with the Financing.

(B)      CONSIDERATION BY BOARD OF DIRECTORS

         The Board of Directors deems the Financing, and the associated
Conversion, to be in the best long-term interests of the Company and its
stockholders for a number of reasons.

         First, the Board of Directors has determined that the $6,500,000 in
cash proceeds will provide the Company with much-needed working capital to
continue to fund its operations. In particular, as contemplated by the
Financing, the Company will use up to approximately $4,200,000 of the cash
proceeds to immediately acquire two additional businesses, which the Board of
Directors believes will provide the Company with greater critical mass and
provide potential value to all stockholders.

         Second, the Board of Directors believes that the associated Conversion
will better enable the Company to list its Common Stock on a national stock
exchange, such as the American Stock Exchange ("AMEX"), thus providing better
liquidity for the Company's stockholders. To qualify its Common Stock for
listing on AMEX, the Company must satisfy a number of substantive listing
requirements, one of which requires that the Company have shareholders' equity
(as set forth on its balance sheet) of at least $4,000,000. As of December 31,
2004, the Company had negative shareholders' equity as reflected on its balance
sheet (without taking in account any potential impairment charges against
goodwill, if any, that may be required to be recognized). This calculation of
shareholders' equity, however, does not reflect any of the Company's current
outstanding shares of Preferred Stock. By converting shares of Series B and B-1
Preferred Stock to Common Stock pursuant to the Conversion, the Company
estimates that it would achieve positive shareholders' equity (again, without
taking into account any potential charges against goodwill, if any, that may
required to be recognized), thus putting the Company in a better position to
qualify its Common Stock for listing on AMEX.

         Third, the Board of Directors has determined that the Financing and
associated Conversion represents the only alternative currently available to the
Company to raise working capital and continue its operations. As the Company has
reported in its current reports on Form 8-K and otherwise, the Company has been
working with various investment banks and advisors since early 2004 to raise
working capital to fund its operations. The Company, however, has not been able
to solicit sufficient interest to consummate a financing to fund its operations.
As a result, the Board of Directors has determined that the Financing represents
the only alternative currently available to the Company to fund its operations.

(C)      RISKS ASSOCIATED WITH THE CONVERSION

         Any decision to approve the Conversion associated with the Financing
involves a number of risks and uncertainties, some of which we have outlined for
you below and others of which are described in the Company's filings on Forms
10-QSB and 10-KSB with the SEC under the heading "Risk Factors, "which may be
reviewed on the SEC's website at WWW.SEC.GOV. You should carefully review and
consider these risks before agreeing to participate in the Financing, certain of
which principal risks we have described in further detail below.




         LOSS OF LIQUIDATION PREFERENCE. Pursuant to the terms of their
respective Certificates of Designation, upon a liquidation, dissolution or
winding-up of the Company (each, a "LIQUIDATION EVENT"), holders of shares of
Series B and Series B-1 Preferred Stock are currently entitled to receive a
liquidation preference equal to $60.00 per share for each share of Series B or
Series B-1 Preferred Stock held by them, to be paid prior and in preference to
any payment to the holders of Common Stock. Upon the Conversion, holders of
Series B and Series B-1 Preferred Stock would convert to Common Stock and forego
their preferences. Holders of Series B and Series B-1 Preferred Stock should
consider, however, that holders of Series C Preferred Stock have a senior
liquidation preference, such that they would receive a liquidation preference
equal to five (5) times their original purchase price ($300.00 per share) prior
to any distribution of funds to holders of Series B and Series B-1 Preferred
Stock. As of the date of this memorandum, there are 307,104 shares of Series C
Preferred Stock currently outstanding or issuable upon the exercise of
outstanding warrants (including the Warrants). With that in mind, MedCap as the
sole holder of all outstanding shares of Series B Preferred Stock will forgo its
liquidation preference upon the conversion of such shares to Common Stock. In
addition, all members of the Company's Board of Directors who hold (and have
held) shares of Series B-1 Preferred Stock are similarly agreeing (or have
previously agreed) to convert such shares to Common Stock.

         SERIES C PREFERRED STOCK LIQUIDATION PREFERENCE. The shares of Series C
Preferred Stock issued upon conversion of the Warrants generally have senior
rights, preferences and privileges to all other classes and series of the
Company's capital stock. Such senior rights include a liquidation preference
entitling such holders to receive five (5) times their original purchase price
prior to any distribution of funds to holders of Series B and Series B-1
Preferred Stock. As a result, upon a sale or dissolution of the Company, MedCap
would receive $32,500,000 in proceeds on account of their exercise of the
Warrants, prior to any distribution of funds to any other stockholder, in
addition to approximately $59,631,200 that other holders of Series C Preferred
Stock (including MedCap) would receive on account of their Series C Preferred
Stock ownership (assuming the exercise of the Warrants and all other warrants to
purchase shares of Series C Preferred Stock).

         DILUTION IN VALUE OF INVESTMENT. As indicated above, the Company needs
the Financing to continue its current operations and may need to raise
additional funds to further its business plan. Although the Warrants are
currently outstanding and may be exercised by MedCap at any time, the shares of
Series C Preferred Stock issued upon exercise of Warrants will represent
approximately 17.6% of the Company on an as-converted to Common Stock basis and
will result in immediate dilution to all holders of the Company's capital stock,
options and warrants.

         LACK OF LIQUIDITY FOR COMPANY COMMON STOCK. The shares of Common Stock
which will be issued to holders of Series B and Series B-1 Preferred Stock will
not be immediately registered under the Securities Act and will be subject to
restrictions on transfer under the Securities Act in the absence of registration
or the availability of a resale exemption, such as Rule 144(k). Although the
Company has agreed to register the resale of such shares of Common Stock with
the SEC within nine months of the closing of the Financing, such holders may
still be unable to sell all of their shares of Common Stock, at the price or
upon such other terms and conditions, as such holders may desire.



(D) ACTIONS REQUESTED OF YOU IN CONNECTION WITH SPECIAL MEETING OF STOCKHOLDERS

         In connection with its approval of the Financing, the Board of
Directors has called the Special Meeting to approve the Conversion. As
indicated, the Special Meeting will be held at the Company offices at 14114

is adjourned. The Board of Directors has fixed the close of business on March 4,
2005 as the record date for determining the stockholders entitled to notice of

         As of the close of business on the Record Date, there were 3,750,000
shares of Series B Preferred Stock and 93,043 shares of Series B-1 Preferred
Stock outstanding and entitled to vote at the Special Meeting. The presence at
the Annual Meeting of a majority of each of the Series B Preferred Stock and
Series B-1 Preferred Stock, either in person or by proxy, voting together as a
single class will constitute a quorum for the transaction of business at the
Special Meeting. The Company's Secretary, Vicki Smith, will tabulate votes cast
