                              VALUEACT CAPITAL

October 13, 2004

Mr. Fred Zeidman
Chairman, Interim President and CEO 
Seitel, Inc.
10811 S. Westview Circle
Bldg. C, Ste. 100
Houston, TX 77043

Dear Fred:

This letter is a follow-up to the previous conversations that we at ValueAct
Capital have had with you and other representatives of the Seitel (the
"company") Board of Directors. To begin, we would like to again acknowledge
your work as Chairman of the Board in helping navigate Seitel, through a
circuitous path, to its present position as a standalone public company.  We
do feel that the company today is largely separated from its controversial
history.  Non-core oil production assets have been divested, cash flows have
been redirected to debt reduction, and some important first steps have been
made to institute internal controls.  These actions have been important in
refocusing the business on the single core activity of building seismic data
libraries. Our belief in Seitel's positive direction has been supported by
our actions, as ValueAct Capital now owns more than 12% of the company.
  
However, we must admit to having been disappointed to learn in the press
release dated October 5, 2004 that Randall Stilley, the company's Chief
Executive Officer, had resigned to accept another position in the oil service
industry.  We strongly believe that after his many months of employment, the
company's inability to deliver a concrete incentive option award provided
Stilley with no guarantee of participating in the rewards of any successes
under his tenure. It appears to us that he had little choice but to look out
for his own interests and consider other alternatives. 

While we recognize that option grants at Seitel might be more complex in
their design given the nature of the bankruptcy and restructuring, we are
nevertheless disappointed that this was not addressed in a more aggressive
and effective manner.  A more timely undertaking of installing management
incentives at the company might have enable it to have retained  Mr.
Stilley.

Under Mr. Stilley's brief tenure, it appears to us that the company's 
culture had begun to demonstrate the initial signs of critical 
positive change.  We understand that procedures have been adopted to 
evaluate capital investment more critically, and that the historical 
mismatch of cash and GAAP incentive award issues has been addressed.  We 
are hopeful that the continuity of these positive changes can be continued 
by the company's Chief Financial Officer.  However, a job of this 
magnitude cannot be successfully accomplished for long by a single
individual.  Thus, the most important immediate decision facing this board 
is the recruitment of a new Chief Executive Officer. 


                               Page 12 of 13


The importance of this decision is further magnified by the company's
significantly leveraged capital structure.  The company's balance sheet
offers little margin for error if the company is to successfully execute on
its business plan.  Strong leadership is particularly important for Seitel 
at this moment in time.

As we have discussed, the principals of ValueAct Capital have extensive,
direct experience as positive, productive and creative members of public
company boards.  In particular, we have direct experience in overseeing CEO
searches with successful outcomes. Additionally, we are also experienced in
developing incentive equity programs for senior management teams.  

Based on our experiences, the present highly leveraged capital structure at
the company, the current void of permanent senior leadership, and the
positive dynamics of having a significant shareholder working alongside the
existing board members, we respectfully request that the Board of Seitel
consider the following:

- The company immediately names me to fill the vacant seat on the Board
made available by Mr. Stilley's resignation.  
- The Board immediately name Mr. Jay Golding, a successful Houston
entrepreneur, as an Advisory Director to the Board; and that Mr. Golding
be added to the Board by way of an expansion of the Board at the soonest
practical time.  
- The Board create an Executive Committee, and that a representative of
the current Seitel Board, Mr. Golding and I be appointed to serve on that
committee.  Among other duties, this committee would immediately begin a
search process for the company's new Chief Executive Officer.  We also ask
that the Executive Committee meet weekly in order to review and approve
selected capital programs at the company, until a new CEO has been
identified and retained.

At ValueAct Capital, we have worked hard to develop a successful track record
and positive reputation for sound decision making in our other investments
where we have joined boards. Our request above is not made lightly, but
rather has been carefully considered with the sole objective of preserving
and enhancing the value of Seitel for all shareholders.  Our intention is to
do all that we can to continue to develop Seitel's sustainable profits and
free cash flows. We also believe that this proposal will be supported by many
of the company's other large investors.
 
Finally, I would like to communicate our respect and appreciation for the
time and energy you have personally invested in the company, working to
ensure that shareholders retain the opportunity to participate in the
company's further growth.  We also strongly believe that the combination of
our sizable investment in the company, experience and reputation for positive
work in other similar situations, and the current state of management
uncertainty at Seitel, warrants our involvement as suggested above.

Feel free to contact me with any questions.  I look forward to discussing 
our request with you and the Board at your earliest convenience.

Sincerely,

Peter H. Kamin
Partner
