                      UNDERLYING REPRESENTATIVE'S WARRANTS

GENERAL

     This Prospectus Supplement contains information regarding (i) the exercise
of substantially all of the redeemable common stock purchase warrants
("Warrants") of Mitcham Industries, Inc., a Texas corporation (the "Company"),
which were sold to the public in the Company's initial public offering in
January 1995 (the "IPO") of units consisting of two shares of common stock,
$0.01 par value per share ("Common Stock") and one Warrant; and (ii) the
amendment and extension of the Exclusive Lease Referral Agreement between the
Company and Input/Output, Inc. ("I/O"), a leading designer and manufacturer of
land-based 3-D data acquisition equipment and systems, both of which events have
occurred since the date of the Company's Prospectus, dated May 29, 1996.

EXERCISE AND REDEMPTION OF PUBLIC WARRANTS

     On April 29, 1996, the Company called for redemption its outstanding
Warrants.  Each Warrant entitled the registered holder thereof to purchase one
share of Common Stock of the Company at a price of $3.50 per share, subject to
adjustment in certain circumstances, through December 1997 (unless sooner called
for redemption).  The Warrants were required to be exercised by 5:00 p.m.
Eastern Standard time, on May 29, 1996 (the "Redemption Date").  After the
Redemption Date, all rights of remaining holders of Warrants ceased, except only
the right to receive the redemption price of $0.05 per Warrant.  As of the date
of the Prospectus, a total of 463,873 Warrants had been exercised.  As of the
Redemption Date, a total of 892,750 of the 895,000 Warrants that were offered
and sold in the IPO had been exercised.  As of the

                                _________________

             The Date of this Prospectus Supplement is July 18, 1996


date of the Prospectus, the Company had received proceeds from the exercise of
the Warrants of approximately $1.6 million.  As of the Redemption Date, the
Company had received proceeds from the exercise of the Warrants of approximately
$3.1 million.  See "The Offering," "Initial Public Offering," "Use of Proceed"
and "Description of Capital Stock - Public Warrants" on pages 5, 7, 13 and 37,
respectively, of the Prospectus.

AMENDMENT AND EXTENSION OF EXCLUSIVE LEASE REFERRAL AGREEMENT WITH INPUT/OUTPUT,
INC.

     Effective June 1, 1996, the Company entered into an amendment of its
Exclusive Lease Referral Agreement (the "I/O Agreement") with I/O.  The I/O
Agreement was entered into in February 1994, under which agreement the Company
(i) was the exclusive third-party recipient of requests from I/O customers and
others to lease I/O three-dimensional ("3-D") channel boxes in North and South
America through December 1996; and (ii) was able to acquire 3-D channel boxes
from I/O at favorable prices based upon the volume of channel boxes purchased.
Subject to certain exceptions, I/O could not recommend or suggest any competitor
of the Company as a potential lessor of I/O 3-D channel boxes in North and South
America.  As a manufacturer of complete data acquisition systems that are
compatible only with I/O channel boxes, I/O typically receives significant
inquiries to lease I/O 3-D channel boxes from customers desiring to expand the
capacities of their systems on a short-term basis.

     In order to receive the benefits of the I/O Agreement, the Company was
required to  purchase an aggregate of $10.0 million of I/O 3-D channel boxes in
stated installments over the term of the agreement, which was to terminate on
December 31, 1996 (the "Termination Date").   As of the date of the Prospectus,
the Company had purchased approximately $7.9 million of the required $10.0
million of I/O 3-D channel boxes under the I/O Agreement, and was required to
purchase an additional $2.1 million of channel boxes on or before the
Termination Date.  The Company had proposed an extension of the I/O Agreement on
substantially similar terms.

     Under the I/O Agreement as amended, (i) the term has been extended until
May 31, 2000; (ii) the seismic data acquisition equipment that I/O will sell to
the Company and with respect to which I/O will recommend the Company as a
potential lessor has been expanded; and (iii) the former aggregate minimum
purchase requirement of $10.0 million no longer applies.  The other provisions
of the I/O Agreement remain substantially the same.

     In addition to I/O 3-D channel boxes that were the subject of the agreement
before the amendment, the I/O Agreement now covers (i) ocean bottom cable
systems, which collect seismic data in an ocean environment in depths of up to
200 meters; (ii) central electronics units, which act as the control center of
and test all functions of complete data acquisition systems; and (iii) remote
acquisition modules, field communication devices between channel boxes and
central electronics units that allow more channel boxes to be employed in a
seismic survey (all of the foregoing seismic equipment subject to the I/O
Agreement referred to collectively as the "I/O Equipment").

     In place of the former aggregate $10.0 million of required purchases,
Company has agreed to purchase an aggregate of $3.0 million of I/O 3-D channel
boxes after June 1, 1996 and before November 30, 1996 (the "Renewal Purchase"),
with a minimum of $1.5 million to be purchased by August 31, 1996.  The Renewal
Purchase is necessary in order for the Company to continue to receive the
benefits of I/O Agreement, which will have no further force



or effect if the Renewal Purchase is not timely made.  As long as the Renewal
Purchase is timely made, the Company will continue as I/O's exclusive recipient
of seismic leasing requests I/O receives from its customers and others in North
and South America and will be able to acquire channel boxes at favorable prices
based upon the volume of I/O Equipment purchased.

     Specifically, from January 1, 1997 through May 31, 1997, the Company must
purchase at least an aggregate of $1.25 million of I/O Equipment in order to
receive favorable pricing with respect to such equipment.  In each of the years
from June 1, 1997 through May 31, 1998, June 1 through May 31, 1999 and June 1,
1999 through May 31, 2000, the Company must purchase at least an aggregate of
$3.0 million of I/O Equipment (or an aggregate additional $10.25 million after
the $3.0 million Renewal Purchase is made) in order to receive favorable pricing
on such equipment.  The Company's failure to meet the minimum purchase
requirements in any such period will not affect its ability to receive favorable
pricing in a subsequent period.

     The Company anticipates that the cash flow generated from the I/O 3-D
channel boxes which it currently owns, the available portions of its $1.0
million line of credit with a bank and its $4.2 million term loan with a bank,
and all or a portion of the approximately $4.2 million aggregate proceeds it has
received from the exercise of the Warrants, bridge warrants, and
representative's warrants issued to the representative of the underwriters in
the Company's IPO, will be used to fund $1.5 million of the Renewal Purchase by
August 15, 1996 and the remaining $1.5 million of the Renewal Purchase by
November 30, 1996.  The Company anticipates that the foregoing sources will fund
in part the remaining aggregate $10.25 million of subsequent minimum purchases
required over the term of the I/O Agreement in order to receive favorable
pricing on such equipment.   However, the Company anticipates that it may
require additional equipment loans in order to fully fund those minimum purchase
requirements.  There can be no assurance that the Company will be able to obtain
such equipment financing loans on terms acceptable to the Company, if at all.
Failure to meet the minimum purchase requirement in one or more years would mean
the loss of favorable pricing provided for by the I/O Agreement, which would
have a material adverse effect on the Company's future operations and profits.
See "Business--Exclusive Lease Referral Agreement with Input/Output, Inc." on
page 24 of the Prospectus.
