                   (Form S-3, Fi1e No. 333-127507 & Form 10-Q, File No. 1-12372)
                   -------------------------------------------------------------

Dear Ms. Long:

Enclosed herewith is Company's responses to the Staff's comment letter (the
"Comment Letter") dated August 26, 2005 concerning the Company's Registration
Statement on Form S-3 (the "Registration Statement") and the Company's Quarterly
Report on Form 10-Q for the period ended June 30, 2005 (the "Form 10-Q").

To facilitate the Staff's review, we have included in this letter the captions
and numbered comments in bold text and have provided the Company's responses
immediately following each numbered comment. The following are the Company's
responses to the Comment Letter:

Registration Statement on Form S-3
----------------------------------

1.       With respect to the debt securities and preferred stock, be advised
         that the convertible securities may not be issued for "other
         securities" that have not been registered under this registration
         statement unless the convertible securities exercisable for such other
         securities are not legally exercisable immediately or within one year
         of the date of sale of the convertible securities. All of the
         underlying classes of securities to which the convertible securities
         relate must be identified in the registration statement, including the
         fee table.

     The Company acknowledges and agrees that any convertible securities that
     may be issued under the Registration Statement will not be issued for
     "other securities" that have not been registered under the Registration
     Statement unless they are not legally exercisable for at least a year from
     the date of sale of the convertible securities.

Plan of Distribution, page 23
-----------------------------

2.       Rule 415(a)(4) requires that in an "at the market" equity offering by
         the registrant, the underwriter must be named in a prospectus that is
         "part of the registration statement." If the registration statement
         becomes effective without naming the underwriter, please confirm
         supplementally that a post-effective amendment will be filed for this
         purpose. Please also confirm that any take downs of voting stock from
         the shelf will comply with the aggregate market value limit imposed by
         Rule 415(a)(4).

     The Company agrees that (i) it will not undertake an "at the market
     offering" unless the underwriter is named by post-effective amendment to
     the Registration Statement and (ii) any take downs of voting stock from the
     Registration Statement will comply with the aggregate market value limit
     imposed by Rule 415(a)(4).

Legality Opinion
----------------

3.       You are reminded that an unqualified legality opinion is required with
         every takedown of securities registered under this registration
         statement. You may file the clean opinions pursuant to Rule 462(d) or
         on Form 8-K.

         The Company will provide a clean legal opinion regarding the validity
         of the securities issued under the Registration Statement by filing a
         Form 8-K.

Quarterly Report on Form 10-Q for period ending June 30, 2005
-------------------------------------------------------------

Item 4. Controls and Procedures, page 30
----------------------------------------

4.       We note your statement that your chief executive officer and your chief
         financial officer "have concluded that the Company's current disclosure
         controls and procedures are reasonably effective." It does not appear
         that your certifying officers have reached a conclusion that your
         disclosure controls and procedures are effective. Please revise to
         address your officers' conclusions regarding the effectiveness of your
         disclosure controls and procedures.

At the time of the filing of the Form 10-Q, the certifying officers had
concluded that the Company's disclosure controls and procedures were effective
as of June 30, 2005. The Company will reflect this comment in all future filings
with the Securities and Exchange Commission.
