               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


ITEM 3.     INCORPORATION OF DOCUMENTS BY REFERENCE.

            The following documents are hereby incorporated by reference in
this Registration Statement:

            1.      The Registration Statement on Form S-1 of OYO Geospace
Corporation, a Delaware corporation (the "Registrant") (Reg. No. 333-36727),
originally filed with the Securities and Exchange Commission (the "Commission")
on September 30, 1997, as amended by Amendment No. 1 thereto, filed with the
Commission on November 5, 1997 and Amendment No. 2 thereto, filed with the
Commission on November 18, 1997; and

            2.      The description of the Registrant's Common Stock, par value
$.01 per share, contained in the Registration Statement on Form S-1 of the
Registrant (Reg. No. 333-36727), originally filed with the Commission on
September 30, 1997, including any amendment or report filed for the purpose of
updating such description.

            All documents filed by the Registrant pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act")
subsequent to the date of the filing hereof and prior to the filing of a
post-effective amendment which indicates that all securities offered hereunder
have been sold or which deregisters all securities then remaining unsold, shall
be deemed to be incorporated by reference in this Registration Statement and to
be a part hereof from the date of filing of such documents.


ITEM 4.     DESCRIPTION OF SECURITIES.

            Not applicable.


ITEM 5.     INTERESTS OF NAMED EXPERTS AND COUNSEL.

            Certain legal matters in connection with the securities offered
hereby are being passed upon for the Registrant by Fulbright & Jaworski L.L.P.,
Houston, Texas.  Charles H. Still, a partner of Fulbright & Jaworski L.L.P., is
Secretary of the Registrant and will be elected as a director of the Registrant
immediately after the closing of the Registrant's initial public offering.


ITEM 6.     INDEMNIFICATION OF DIRECTORS AND OFFICERS.

            The Registrant's Restated Certificate of Incorporation contains a
provision that eliminates the personal liability of a director to the
Registrant and its stockholders for monetary damages for breach of his
fiduciary duty as a director to the extent currently allowed under the General
Corporation Law of the State of Delaware (the "DGCL").  If a director were to
breach such duty in performing his duties as a director, neither the Registrant
nor its stockholder could recover monetary damages from the director, and the
only course of action available to the Registrant's stockholders would be
equitable remedies, such as an action to enjoin or rescind a transaction
involving a breach of fiduciary duty.  To the extent certain claims against
directors are limited to equitable remedies, the provision in the Registrant's
Restated Certificate of Incorporation may reduce the likelihood of derivative
litigation and may discourage stockholders or management from initiating
litigation against directors for breach of their fiduciary duty.  Additionally,
equitable remedies may not be effective in many situations.  If a stockholder's
only remedy is to enjoin the completion of the Board of Directors' action, the
remedy would be ineffective if the stockholder does not become aware of a
transaction or event until after it has been completed.  In such a situation,
it is possible that the stockholders and the Registrant would have no effective
remedy against the directors.  Under the Registrant's Restated Certificate of
Incorporation, liability for monetary damages remains for (i) any breach of the
duty of loyalty to the Registrant or its stockholders, (ii) acts or omissions
not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) payment of an improper dividend or improper repurchase
of the Registrant's stock under Section 174 of the DGCL or (iv) any transaction
from which the director derived an improper personal benefit.  The





                                      II-1
<PAGE>   3
Registrant's Restated Certificate of Incorporation further provides that in the
event the DGCL is amended to allow the further elimination or limitation of the
liability of directors, then the liability of the Registrant's directors shall
be limited or eliminated to the fullest extent permitted by the amended DGCL.

            Under the Registrant's Bylaws, each person who is or was a director
or officer of the Registrant or a subsidiary of the Registrant, or who serves
or served any other enterprise or organization at the request of the Registrant
or a subsidiary of the Registrant, shall be indemnified by the Registrant to
the full extent permitted by the DGCL.

            Under Delaware law, to the extent that a person is successful on
the merits in defense of a suit or proceeding brought against him by reason of
the fact that he is or was a director or officer of the Registrant, or serves
or served any other enterprise or organization at the request of the
Registrant, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred in connection with such action.

            Under Delaware law, to the extent an indemnified person is not
successful in defense of a third party civil suit or a criminal suit, or if
such suit is settled, such person shall be indemnified against both (i)
expenses, including attorneys' fees, and (ii) judgments, fines and amounts paid
in settlement if he acted in good faith and in a manner he reasonably believed
to be in, or not opposed to, the best interests of the Registrant and, with
respect to any criminal action, had no reasonable cause to believe his conduct
was unlawful, except that if such person is adjudged to be liable in such a
suit for negligence or misconduct in the performance of his duty to the
Registrant, he cannot be made whole even for expenses unless the court
determines that he is fully and reasonably entitled to indemnity for such
expenses.

            The Registrant intends to obtain insurance to protect officers and
directors from certain liabilities, including liabilities against which the
corporation cannot indemnify its directors and officers.

            The Registrant will enter into indemnification agreements with each
of the directors of the Registrant.  Pursuant to such agreements, the
Registrant will agree to indemnify and hold each such director harmless to the
fullest extent permitted by law, from any loss, damage or liability incurred in
the course of his respective service as a director of the Registrant.  The
amount paid by the Registrant is reducible by the amount of insurance paid to
or on behalf of such director with respect to any event giving rise to
indemnification.  Each such director's right to indemnification is to survive
his respective death or termination as director.

            The Registrant's Bylaws provide for the indemnification of its
officers and directors and the advancement to them of expenses in connection
with proceedings and claims, to the fullest extent permitted under the DGCL.
Such indemnification may be made even though directors and officers would not
otherwise be entitled to indemnification under other provisions by the Bylaws.

            The above discussion of the DGCL and of the Registrant's Restated
Certificate of Incorporation and Bylaws is not intended to be exhaustive and is
qualified in its entirety by such statute and the Restated Certificate of
Incorporation and Bylaws.

ITEM 9.     UNDERTAKINGS.

            The undersigned Registrant hereby undertakes:

            (1)     To file, during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:

                    (i)     To include any prospectus required by Section
10(a)(3) of the Securities Act;

                    (ii)    To reflect in the prospectus any facts or events
arising after the effective date of this Registration Statement (or the most
recent post-effective amendment hereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement.  Notwithstanding the foregoing, any increase or
decrease in volume of securities offered (if the total dollar volume of
securities offered would not exceed that which was registered) and any
deviation from the low or high end of the estimated maximum offering range may
be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration
statement; and

                    (iii)   To include any material information with respect to
the plan of distribution not previously disclosed in this Registration
Statement or any material change to such information in this Registration
Statement;

            Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with or furnished to
the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in this Registration Statement.

            (2)     That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3)     To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

            The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual





                                      II-3
<PAGE>   5
report pursuant to Section 15(d) of the Securities Act) that is incorporated by
reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.     INCORPORATION OF DOCUMENTS BY REFERENCE.

            The following documents are hereby incorporated by reference in
this Registration Statement:

            1.      The Registration Statement on Form S-1 of OYO Geospace
Corporation, a Delaware corporation (the "Registrant") (Reg. No. 333-36727),
originally filed with the Securities and Exchange Commission (the "Commission")
on September 30, 1997, as amended by Amendment No. 1 thereto, filed with the
Commission on November 5, 1997 and Amendment No. 2 thereto, filed with the
Commission on November 18, 1997; and

            2.      The description of the Registrant's Common Stock, par value
$.01 per share, contained in the Registration Statement on Form S-1 of the
Registrant (Reg. No. 333-36727), originally filed with the Commission on
September 30, 1997, including any amendment or report filed for the purpose of
updating such description.

            All documents filed by the Registrant pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934 (the "Exchange Act")
subsequent to the date of the filing hereof and prior to the filing of a
post-effective amendment which indicates that all securities offered hereunder
have been sold or which deregisters all securities then remaining unsold, shall
be deemed to be incorporated by reference in this Registration Statement and to
be a part hereof from the date of filing of such documents.

ITEM 4.     DESCRIPTION OF SECURITIES.

            Not applicable.

ITEM 5.     INTERESTS OF NAMED EXPERTS AND COUNSEL.

            Certain legal matters in connection with the securities offered
hereby are being passed upon for the Registrant by Fulbright & Jaworski L.L.P.,
Houston, Texas.  Charles H. Still, a partner of Fulbright & Jaworski L.L.P., is
Secretary of the Registrant and will be elected as a director of the Registrant
immediately after the closing of the Registrant's initial public offering.

ITEM 6.     INDEMNIFICATION OF DIRECTORS AND OFFICERS.

            The Registrant's Restated Certificate of Incorporation contains a
provision that eliminates the personal liability of a director to the
Registrant and its stockholders for monetary damages for breach of his
fiduciary duty as a director to the extent currently allowed under the General
Corporation Law of the State of Delaware (the "DGCL").  If a director were to
breach such duty in performing his duties as a director, neither the Registrant
nor its stockholder could recover monetary damages from the director, and the
only course of action available to the Registrant's stockholders would be
equitable remedies, such as an action to enjoin or rescind a transaction
involving a breach of fiduciary duty.  To the extent certain claims against
directors are limited to equitable remedies, the provision in the Registrant's
Restated Certificate of Incorporation may reduce the likelihood of derivative
litigation and may discourage stockholders or management from initiating
litigation against directors for breach of their fiduciary duty.  Additionally,
equitable remedies may not be effective in many situations.  If a stockholder's
only remedy is to enjoin the completion of the Board of Directors' action, the
remedy would be ineffective if the stockholder does not become aware of a
transaction or event until after it has been completed.  In such a situation,
it is possible that the stockholders and the Registrant would have no effective
remedy against the directors.  Under the Registrant's Restated Certificate of
Incorporation, liability for monetary damages remains for (i) any breach of the
duty of loyalty to the Registrant or its stockholders, (ii) acts or omissions
not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) payment of an improper dividend or improper repurchase
of the Registrant's stock under Section 174 of the DGCL or (iv) any transaction
from which the director derived an improper personal benefit.  The

                                      II-1
3
Registrant's Restated Certificate of Incorporation further provides that in the
event the DGCL is amended to allow the further elimination or limitation of the
liability of directors, then the liability of the Registrant's directors shall
be limited or eliminated to the fullest extent permitted by the amended DGCL.

            Under the Registrant's Bylaws, each person who is or was a director
or officer of the Registrant or a subsidiary of the Registrant, or who serves
or served any other enterprise or organization at the request of the Registrant
or a subsidiary of the Registrant, shall be indemnified by the Registrant to
the full extent permitted by the DGCL.

            Under Delaware law, to the extent that a person is successful on
the merits in defense of a suit or proceeding brought against him by reason of
the fact that he is or was a director or officer of the Registrant, or serves
or served any other enterprise or organization at the request of the
Registrant, he shall be indemnified against expenses (including attorneys'
fees) actually and reasonably incurred in connection with such action.

            Under Delaware law, to the extent an indemnified person is not
successful in defense of a third party civil suit or a criminal suit, or if
such suit is settled, such person shall be indemnified against both (i)
expenses, including attorneys' fees, and (ii) judgments, fines and amounts paid
in settlement if he acted in good faith and in a manner he reasonably believed
to be in, or not opposed to, the best interests of the Registrant and, with
respect to any criminal action, had no reasonable cause to believe his conduct
was unlawful, except that if such person is adjudged to be liable in such a
suit for negligence or misconduct in the performance of his duty to the
Registrant, he cannot be made whole even for expenses unless the court
determines that he is fully and reasonably entitled to indemnity for such
expenses.

            The Registrant intends to obtain insurance to protect officers and
directors from certain liabilities, including liabilities against which the
corporation cannot indemnify its directors and officers.

            The Registrant will enter into indemnification agreements with each
of the directors of the Registrant.  Pursuant to such agreements, the
Registrant will agree to indemnify and hold each such director harmless to the
fullest extent permitted by law, from any loss, damage or liability incurred in
the course of his respective service as a director of the Registrant.  The
amount paid by the Registrant is reducible by the amount of insurance paid to
or on behalf of such director with respect to any event giving rise to
indemnification.  Each such director's right to indemnification is to survive
his respective death or termination as director.

            The Registrant's Bylaws provide for the indemnification of its
officers and directors and the advancement to them of expenses in connection
with proceedings and claims, to the fullest extent permitted under the DGCL.
Such indemnification may be made even though directors and officers would not
otherwise be entitled to indemnification under other provisions by the Bylaws.

            The above discussion of the DGCL and of the Registrant's Restated
Certificate of Incorporation and Bylaws is not intended to be exhaustive and is
qualified in its entirety by such statute and the Restated Certificate of
Incorporation and Bylaws.

Statement;

            Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic reports filed with or furnished to
the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Exchange Act that are incorporated by reference in this Registration Statement.

            (2)     That, for the purpose of determining any liability under
the Securities Act, each such post-effective amendment shall be deemed to be a
new registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (3)     To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

            The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual

                                      II-3

report pursuant to Section 15(d) of the Securities Act) that is incorporated by
reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered herein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
