February 08, 2018
Board of Directors
Geospace Technologies Corporation
7007 Pinemont Drive
Houston, Texas 77040

Dear Directors:
Lemelson Capital Management LLC, as the beneficial
owner of approximately 10 percent of Geospace
Technologies ("Geospace") outstanding shares is calling
for the immediate removal, for cause, of Mr. Rick
Wheeler, CEO and Mr. Tom McEntire, CFO of Geospace
Technologies and the for the board to immediately
explore a sale of the company.
We are extremely troubled by the following conduct of
Messrs. Wheeler and McEntire, including but not limited
to:
1.	Knowingly filing a materially misleading form 8-K
with the Securities and Exchange Commission
(SEC) regarding the tally of votes at the annual
shareholder meeting held on February 8, 2018.
2.	The recent material weakness in the Company's
internal control over financial reporting, including
management's failure to design and maintain
controls over the classification of inventory, as of
September 30, 2017 and 2016 that led to the
restatement of previously filed annul and interim
reports and adverse audit opinions.
3.	The dysfunction and incompetence being exhibited
in the process of maximizing stockholder value
that the Board is purportedly "handling" and which
has led to the loss of major contracts.
The failed management of Mr. Wheeler and Mr. McEntire
has caused the stock price of Geospace to recently hit a
new 52-week low, (plummeting nearly 90 percent since
Mr. Wheeler took over as CEO in January 2014), despite
the extraordinary industry-wide recovery in the oil and
gas sector which has led to the stock price of several of
the company's competitors recently achieving new 52-
week highs.
We are disturbed but not surprised by this
mismanagement given the recent history of strategic
bungling by Mr. Wheeler and Mr. McEntire, which has
been chronicled in our previous letters and that has
recently lead to the loss of two major PRM contracts with
Statoil, an existing customer, to an obscure and relatively
inexperienced provider in the industry.
As significant shareholders who take our fiduciary duties
to investors seriously, we cannot stand by silently if
Geospace, a company with vast under-reported and
unencumbered assets, including near-record cash and
liquidity, plans to engage in a campaign of cash
preservation and cost cutting measures which will serve
only to entrench Mr. Wheeler and Mr. McEntire and the
current board while massively disenfranchising public
shareholders and permanently robbing us of the
opportunity to unlock the value in our stake in the
company .
We are not alone in our concerns. Other shareholders are
now publicly questioning the integrity and ability of this
management team.
As stewards of our assets you are charged with a duty to
place stockholder interests above personal gain or other
motives.  To allay the legitimate concerns and
uncertainty now flooding the marketplace and provide
much needed transparency we ask that you immediately
take the following actions:
1.	Make public any correspondence or process in
which Geospace invited or directed third parties to
make motions or alter the vote count (the
"process letters") at the most recent annual
meeting.
2.	 Remove Mr. Wheeler and Mr. McEntire for clearly
breaching their fiduciary responsibilities to
shareholders and for violating securities laws and
regulations by knowing filing a false and
materially misleading form 8-K on February 7,
2018.
3.	 Engage an investment bank to explore strategic
alternatives for a sale of the company.
We assume that Geospace as part of its corporate
governance process at its most recent annual meeting
did not place any artificial restrictions on the proposals or
voting rights that the Geospace board was willing to
consider, such as discouraging, or even prohibiting the
accurate tally of votes cast at the meeting.
Of course, we appreciate the need for confidential
correspondence, and therefore stockholders need not
know at this stage who received the Process Letters.
However, stockholders do need to know that the board's
actions are consistent with their chief duty to maximize
stockholder value.
Additionally, Lemelson Capital does not seek and does
not expect to receive material non-public information and
thus requests that you file such letters publicly with the
Securities and Exchange Commission via Form 8-K with
all deliberate speed.
Considering the serious concerns recently expressed by
many Geospace stakeholders and interested parties,
undertaking these proposed actions is the only
responsible thing to do.
Sincerely,


+ Emmanuel Lemelson

Chief Investment Officer
Lemelson Capital Management, LLC
