Dear Board,

I wish to inform you of my decision to resign my title as
Director with Market Data/Renet Financial Services Corp. and
Renet Financial Corp. effective immediately.

At this time I wish to pursue other business opportunities
available to me.

I will still be available as a contract accountant to assist
Renet Financial Corp. with its bookkeeping as I have been doing
for the past several months.

Dear Sirs:

The undersigned, Steven C. Naremore, hereby resigns all positions
as an officer or director of Market Data Corp., its subsidiaries
and affiliates (collectively "MDC"), effective immediately. 
While I regret the circumstances that require this action, which
I have previously explained to each of you, I believe you can
understand that the previously undisclosed adverse information
regarding Renet Financial appears to be of such a nature, and the
fact of the nondisclosure is of such a nature, that I do not
believe I can any longer fulfill my duties as an officer or
director of MDC with any confidence.  This resignation is
immediate and irreversible.

Please bear in mind that as a public company, MDC has continuing
obligations to disclose all material developments to the public
in a timely fashion.  While I resign as an officer and director,
I remain a significant shareholder, and hereby demand that you
make full, complete, prompt and appropriate public disclosure of
all material developments affecting MDC, particularly those
relating to Renet Financial Corporation as to which you are in
the most knowledgeable position to make.

As contemplated in the reporting requirements of Current Report
on Form 8-K, please bear in mind that this resignation is as a
result of a disagreement of the sort contemplated in Item 6 of
such Form, and that I reserve the right to furnish you prior to
the time of such filing a letter setting forth a description of
such disagreement for summarization in such Form.
