                                PROXY STATEMENT
                   FOR 2003 ANNUAL MEETING OF STOCKHOLDERS
                   ---------------------------------------

General Information

     This proxy statement is furnished to the stockholders of Lifen, Inc., a
Delaware corporation (the "Company"), in connection with the solicitation by the
board of directors of the Company of proxies in the accompanying form for use in
voting at the annual meeting of stockholders of the Company (the "Annual
Meeting") to be held on Wednesday, May 28, 2003, at 1:30 p.m. Pacific Daylight
Time, at the offices of Morrison & Foerster LLP, 425 Market Street, San
Francisco, California 94105, and any adjournment or postponement thereof.  The
shares represented by the proxies received, properly marked, dated, executed and
not revoked will be voted at the Annual Meeting.

     The Company's Internet Web site address is www.crdentia.com.  The Company's
annual reports on Form 10-KSB, quarterly reports on Form 10-QSB, current reports
on Form 8-K, and amendments to those reports filed or furnished pursuant to
Section 13(a) or 15(d) of the Exchange Act are available free of charge in
electronic or paper form upon request to the Company after they are
electronically filed with, or furnished to, the Securities and Exchange
Commission.  All materials filed by the Company with the Commission also can be
obtained at the Commission's Public Reference Room at 450 Fifth Street, N.W.
Washington, D.C. 20549 or through the Commission's Web site at www.sec.gov. You
may obtain information on the operation of the Public Reference Room by calling
1-800-SEC-0330.

Solicitation, Record Date and Voting Procedures

     The solicitation of proxies will be conducted by mail and the Company will
bear all attendant costs.  These costs will include the expense of preparing and
mailing proxy materials for the Annual Meeting and reimbursements paid to
brokerage firms and others for their expenses incurred in forwarding
solicitation material regarding the Annual Meeting to beneficial owners of the
Company's common stock.  The Company may conduct further solicitation
personally, telephonically or by facsimile through its officers, directors and
regular employees, none of whom will receive additional compensation for
assisting with the solicitation.

     The close of business on May 9, 2003 has been fixed as the record date (the
"Record Date") for determining the holders of shares of common stock of the
Company entitled to notice of and to vote at the Annual Meeting. As of the close
of business on the Record Date, the Company had 10,998,166shares of common stock
outstanding and entitled to vote at the Annual Meeting.    The presence at the
Annual Meeting of a majority of these shares of common stock of the Company,
either in person or by proxy, will constitute a quorum for the transaction of
business at the Annual Meeting.  The Company's Secretary, Lawrence M. Davis,
will tabulate votes cast by proxy and act as inspector of elections to tabulate
votes cast in person at the Annual Meeting.  Each outstanding share of common
stock on the Record Date is entitled to one vote on all matters.

     Under the General Corporation Law of the State of Delaware, an abstaining
vote and a broker "non-vote" are counted as present and are, therefore, included
for purposes of determining whether a quorum of shares is present at the Annual
Meeting.  Abstentions are included in determining the number of shares voted on
the proposals submitted to stockholders (other than the election of directors)
and will have the same effect as a "no" vote on such proposals.  A broker "non-
vote" occurs when a nominee holding shares for a beneficial owner does not vote
on a particular matter because the nominee does not have the discretionary
voting power with respect to that matter and has not received instructions from
the beneficial owner.  Broker "non-votes," and shares as to which proxy
authority has been withheld with respect to any matter, are generally not deemed
to be entitled to vote for purposes of determining whether stockholders'
approval of that matter has been obtained.

                                       1



     With respect to proposals 1 and 2 of this proxy statement, the affirmative
vote of a majority of the shares of common stock represented and voted at the
Annual Meeting is required for approval of the amendment to the Amended and
Restated Certificate of Incorporation to change the Company's name and
ratification of the independent auditors.  Abstentions will have the same effect
as "no" votes on proposals 1 and 2, whereas broker "non-votes" will have no
effect on such proposals.

The Proxy

     The persons named as proxyholders, James D. Durham and Lawrence M. Davis,
were selected by the Company's board of directors and currently serve as
executive officers of the Company.

     All shares represented by each properly executed, unrevoked proxy received
in time for the Annual Meeting will be voted in the manner specified therein.
If no specification is made on the proxy as to any one or more of the proposals,
the common stock of the Company represented by the proxy will be voted as to the
proposal for which no specification is given as follows:  FOR the amendment of
Company's Amended and Restated Certificate of Incorporation to change the
Company's name to "Crdentia Corp.", FOR the ratification of the recommendation
of BDO Seidman, LLP, as the Company's independent auditors for the 2003 fiscal
year and, with respect to any other matters that may come before the Annual
Meeting, at the discretion of the proxyholders.  The Company does not presently
know of any other such business to be conducted at the Annual Meeting.

Revocability of Proxy

     If the shares of common stock are held in your name, you may revoke your
proxy given pursuant to this solicitation at any time before the proxy card is
voted by:  (i) delivering to the Company (to the attention of Lawrence M. Davis,
the Company's Secretary), at the address of the Company's principle executive
offices, a written notice of revocation or a duly executed proxy bearing a later
date, or (ii) attending the Annual Meeting and voting in person.  If your shares
are held in "street name," you should follow the directions provided by your
broker regarding how to revoke your proxy.  Your attendance at the Annual
Meeting after having executed and delivered a valid proxy card will not in and
of itself constitute a revocation of your proxy.  You will be required to give
oral notice of your intention to vote in person to the inspector of elections at
the Annual Meeting.


                                       2



                                PROPOSAL NO. 1
     AMENDMENT TO THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO
                          CHANGE THE COMPANY'S NAME.

     The Company's Amended and Restated Certificate of Incorporation currently
provides that the Company's name is "Lifen, Inc."  An increasing portion of the
Company's overall operational strategy is to offer services in the temporary
medical staffing industry, which services the Company had originally planned to
operate under a division with the trade name "Crdentia".  Because the Company
foresees that this division will constitute a substantial portion of the
Company's overall operations, the Company believes that changing its name to
"Crdentia Corp." will better reflect the Company's current business focus.

     By approving this proposal, the stockholders will authorize the board of
directors to amend the Company's Amended and Restated Certificate of
Incorporation to reflect this name change.  The amendment to the Amended and
Restated Certificate of Incorporation will take substantially the following
form:

     "Article I is hereby replaced with a new Article I - 'The name of this
     corporation is Crdentia Corp.' "

Required Vote

     The affirmative vote of the holders of a majority of the shares of the
Company's common stock present or represented at the Annual Meeting is required
to approve the amendment to the Company's Amended and Restated Certificate of
Incorporation.  Abstentions will have the same effect as "no" votes on this
proposal, whereas broker "non-votes" will have no effect.


                  THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR
   THE AMENDMENT TO THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO
                           CHANGE THE COMPANY'S NAME.

                                       3



                                PROPOSAL NO. 2
            RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS

     BDO Seidman, LLP, is being recommended to the shareholders by the board of
directors to be the Company's independent auditors for the fiscal year ending
December 31, 2003.  If this recommendation is ratified by the shareholders, then
the appointment of BDO Seidman, LLP will become effective as of the date of the
Annual Meeting.  The Company anticipates that the proposed audit partner from
BDO Seidman, LLP will attend the Annual Meeting to respond to appropriate
questions from shareholders in attendance.  In the event that ratification of
this selection of independent auditors is not approved by a majority of the
shares of common stock voting at the Annual Meeting in person or by proxy,
management will review its future selection of independent auditors.

     The Company's current independent auditor is Sanford H. Feibusch, CPA, PC.
In connection with his services to the Company in the fiscal year ended December
31, 2002, Mr. Feibusch prepared (i) a report dated February 5, 2003 on the
Company's consolidated financial statements for the four months ended December
31, 2002 and 2001, and for the period from November 10, 1997 (date of inception)
to December 31, 2002, and (ii) a report dated November 7, 2002 on the Company's
consolidated financial statements for the years ended August 31, 2002 and 2001,
and for the period from November 10, 1997 (date of inception) to August 31,
2002.  Neither report contained an adverse opinion or disclaimer of opinion nor
was either qualified or modified as to uncertainty, audit scope, or accounting
principles.  Both opinions were qualified, however, as to the Company's ability
to sustain itself as a going concern without securing additional funding.  In
addition, with respect to each of the reports, there were no disagreements with
Mr. Feibusch on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedures, which disagreements if
not resolved to the satisfaction of Mr. Feibusch would have caused him to make
reference thereto in his report on the financial statements for such periods.
The Company provided Mr. Feibusch with a copy of the foregoing disclosures and
advised him in writing that, if he believed such disclosures to be incorrect or
incomplete, he could present his views in a brief statement, ordinarily expected
not to exceed 200 words, to be included in this proxy statement.

     Fees paid to Mr. Feibusch in 2002 were as follows:

     Audit Fees.  $7,000 for the audit of consolidated financial statements for
     (i) the four months ended December 31, 2002 and 2001, and for the period
     from November 10, 1997 (date of inception) to December 31, 2002, and (ii)
     the for the years ended August 31, 2002 and 2001, and for the period from
     November 10, 1997 (date of inception) to August 31, 2002.

     Financial Information Systems Design and Implementation Fees.  None.

     All Other Fees.  None.

     The Company's management and board are in favor of this change because of
the Company's probable transition from a development stage company to an
operating company in conjunction with the proposed acquisition of New Age
Staffing, Inc.  As such, both the potential size and geographic diversity of the
Company could exceed Mr. Feibusch's capacity to provide the appropriate level of
professional service since he is a sole practitioner.

Required Vote

     The affirmative vote of the holders of a majority of the shares of the
Company's common stock present or represented at the Annual Meeting is required
to approve the ratification of the selection of BDO Seidman, LLP as the
Company's independent auditors for year 2003.  Abstentions will have the same
effect as "no" votes on this proposal, whereas broker  "non-votes" will have no
effect.

        THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE RATIFICATION OF
                      THE SELECTION OF BDO SEIDMAN, LLP.

                                       4

                                 OTHER MATTERS

Form 10-KSB

     The Company's transition report on Form 10-KSB for the four months ended
December 31, 2002 was filed with the Securities and Exchange Commission on
March 11, 2003.  The Company's annual report on Form 10-KSB for the fiscal year
ended August 31, 2002 was filed with the Securities and Exchange Commission on
November 27, 2002.  Upon written request to the Company's Secretary, Lawrence
M. Davis, at the address of the Company's principal executive offices, the
exhibits set forth on the exhibit index of the Form 10-KSB may be made available
at a reasonable charge.

Householding of Annual Meeting Materials

     In December 2000, the Securities and Exchange Commission adopted new rules
that permit the Company to send a single set of annual reports and proxy
statements to any household at which two or more stockholders reside if the
Company believes they are members of the same family.  Each stockholder will
continue to receive a separate proxy card.  The Company is instituting this
householding procedure for all consenting accounts for the 2003 proxy season.
However, upon written request to the Company's Secretary, Lawrence M. Davis, at
the address of the Company's principal executive offices, you may revoke your
decision to household, and the Company will deliver a separate copy of the
annual report or proxy statement, as applicable, to you at the shared address
within 30 days of your request.

     A number of brokerage firms have already instituted householding.  If your
family has multiple accounts of our stock, you may have received householding
notification from your broker.  Please contact your broker directly if you have
questions, require additional copies of the proxy statement or annual report, or
wish to revoke your decision to household, and thereby receive multiple reports.

Other Matters

     The board of directors knows of no other business which will be presented
at the Annual Meeting.  If any other business is properly brought before the
Annual Meeting, it is intended that proxies in the enclosed form will be voted
in respect thereof in accordance with the judgments of the proxyholders.


     It is important that the proxies be returned promptly and that your shares
be represented.  Stockholders are urged to mark, date, execute and promptly
return the accompanying proxy card in the enclosed envelope.

                                       By Order of the Board of Directors,
