PROSPECTUS SUMMARY

The following summary should be read in conjunction with, and is qualified
in its entirety by, the more detailed information and Consolidated Financial
Statements (including the Notes thereto) appearing elsewhere in this Prospectus
and incorporated herein by reference. The term "Company" refers to Mitcham
Industries, Inc. and its wholly-owned subsidiary, Mitcham Canada Ltd., an
Alberta corporation. Unless otherwise indicated, all financial and share
information set forth in this Prospectus assumes no exercise of the
Underwriters' over-allotment option.

THE COMPANY
GENERAL

Mitcham Industries, Inc. leases and sells geophysical and other equipment
used primarily by seismic service companies in performing seismic data
acquisition surveys on land and in transition zones (marsh and shallow water
areas). The Company conducts its operations on a worldwide basis and is the
leading independent seismic equipment lessor in North and South America. Demand
for seismic services has increased significantly in the past several years due
to advances in technology and the impact such advances have had on increasing
drilling success rates, thereby reducing the overall costs of finding oil and
gas. As a result, the Company and many seismic contractors have significantly
expanded their seismic equipment fleets. From January 31, 1994 through October
31, 1997, the Company's equipment lease pool, at cost, increased from
approximately $957,000 to $36.8 million, and the number of advanced seismic data
acquisition recording channels in the equipment lease pool increased from 510
channels to 11,866 channels. The Company's sales of new and used seismic
equipment have also increased significantly.

The Company owns a variety of technologically advanced equipment acquired
from the leading seismic manufacturers. The Company's lease pool includes many
types of equipment used in seismic data acquisition, including all components of
land and transition zone seismic data acquisition systems, geophones and cables,
earth vibrators, peripheral equipment and survey and other equipment. A
substantial portion of the Company's lease equipment is provided by two
manufacturers, Input/Output, Inc. ("I/O") and the Sercel subsidiaries of
Compagnie Generale de Geophysique ("Sercel"). The Company believes that most of
the advanced seismic data acquisition systems in use worldwide are either I/O or
Sercel systems. In the last two years, the Company has significantly diversified
its equipment lease pool. At October 31, 1997, approximately 51% of the
Company's equipment lease pool, on a cost basis, consisted of advanced digital
recording channels, with the remainder consisting of peripheral and other
equipment.

The Company leases its equipment on a short-term basis, generally for three
to nine months, to seismic contractors who need additional capacity to complete
a seismic survey. In doing so, the Company enables its customers to achieve
operating and capital investment efficiencies. Demand for short-term seismic
equipment leases is affected by many factors including: (i) the highly variable
size and technological demands of individual seismic surveys, (ii) seasonal
weather patterns and sporadic demand for seismic services in certain regions,
(iii) rapidly changing technology and (iv) costs of seismic equipment. The
Company believes these factors allow seismic contractors to use short-term
seismic equipment leasing as a cost-effective alternative to purchasing
additional equipment. The Company's equipment lease rates vary according to an
item's expected useful life, utilization and initial cost. For example, monthly
lease rates for seismic recording channel boxes range between 6% and 8% of the
original cost of the equipment.

A typical seismic crew uses a wide variety of equipment to perform seismic
data acquisition surveys. The Company's customers may lease a small amount of
equipment to expand an existing crew's capabilities or a complete seismic data
acquisition system to equip an entire crew. The Company believes that it
achieves high utilization of its equipment and operational efficiencies due to
the large number of equipment items it has available for lease, which provides
the flexibility to meet customers' needs. The Company's lease pool utilization
for the nine months ended October 31, 1997 was approximately 71%. Due to the
varying operating conditions created by seasonal weather patterns, the Company
estimates its maximum lease pool utilization is approximately 75-80%.

of used seismic equipment on a worldwide basis and, in certain markets, acts as
a sales representative or distributor for new seismic equipment.

The Company has supply and exclusive lease referral agreements with several
leading seismic equipment manufacturers including I/O, Sercel and Pelton
Company, Inc. ("Pelton"). The Company believes that these agreements provide it
with a significant competitive advantage. Under these agreements, the Company is
the exclusive worldwide short-term leasing representative for certain products,
except in the case of the I/O Agreement, which limits the Company's exclusivity
to the Western Hemisphere. Additional agreements exist with certain of these
manufacturers allowing the Company to act as sales representative or distributor
for such manufacturer's products in selected markets. These agreements have
varying terms and expire in 1997 through 2000, subject to modification or
extension. See "Business -- Key Supplier Agreements."

THE INDUSTRY

Seismic surveys are a principal source of information used by oil and gas
companies to identify geological conditions that are favorable for the
accumulation of oil and gas and to evaluate the potential for successful
drilling, development and production of oil and gas. Seismic technology has been
used by the oil and gas industry since the 1920's and has advanced significantly
with improvements in computing and electronic technologies. In recent years, the
oil and gas industry has significantly expanded its use of 3-D seismic, which
provides a more comprehensive subsurface image and is believed to have
contributed to improved drilling success rates, particularly in mature oil and
gas basins such as those in North America. Additionally, 2-D seismic data
continues to be used in many areas where 3-D data acquisition is cost
prohibitive or logistical access is limited.

Recent industry advances include the use of high resolution 2-D,
three-component geophones ("3C-3D"), which enhance the 3-D image, and time lapse
("4-D") seismic, where surveys are periodically reacquired to allow the
monitoring of a producing oil and gas field for optimal production and reserve
recovery. These and other technical advances have contributed to increased
drilling success rates and reduced oil and gas finding costs and consequently,
have increased demand for seismic data acquisition equipment and services.

With the expanded use of seismic technology, particularly 3-D seismic, the
size of data acquisition surveys has increased substantially in the past several
years. Demand for higher resolution data, larger surveys and more rapid
completion of such surveys is requiring seismic acquisition companies to use
data acquisition systems with a greater number of seismic recording channels.
Additionally, in many areas, such as North America, the size of seismic surveys
varies significantly, requiring frequent changes in the configuration of
equipment and crews used for seismic surveys. As a result of these advances,
seismic survey channel count has increased from smaller 2-D surveys, which
typically averaged 120 channels, to larger 3-D surveys which today average
approximately 1,500 channels and often use 3,000 or more channels. The Company
believes that many seismic service companies will continue to meet changes in
equipment needs by leasing incremental equipment to expand crew size as
necessary to meet specific survey requirements, and thereby reduce the
substantial capital expenditures necessary to purchase such equipment.

BUSINESS STRATEGY

The Company's business strategy is to meet the expanding needs of users of
seismic equipment through its leasing and support services. To accomplish this,
the Company has identified the following major objectives:

- Enlarge and diversify the seismic equipment lease pool. Due to the
increasing demand for seismic services and the expanding size and
variability of seismic surveys, the Company intends to continue to
increase the size and diversity of its equipment lease pool. The Company
believes that the availability of a larger and more diverse seismic
equipment lease pool will encourage seismic survey companies to lease,
rather than purchase, such equipment, due to the capital and operating
efficiencies provided by short-term leases. The Company is also
evaluating the feasibility of broadening its equipment lease pool to
include certain marine seismic equipment.

leasing activities in South America and other international locations
have increased significantly. The Company believes that it will be able
to expand its international leasing activities as its equipment lease
pool expands and as its customers' operations continue to grow in
international markets. The Company receives referrals from Sercel and
other manufacturers on a worldwide basis. The Company believes that its
alliances with manufacturers will help it to further penetrate
international markets, where such manufacturers are well-recognized and
have well-developed business relationships.

- Develop and enhance alliances with major seismic equipment
manufacturers. The Company's alliances with leading seismic equipment
manufacturers such as I/O and Sercel allow it to expand its equipment
lease pool on favorable terms and increase customer referrals. The
Company believes such alliances improve its relations with customers and
provide a significant competitive advantage. The Company has exclusive
short-term lease agreements with four manufacturers and is seeking to
expand the scope of existing alliances, as well as develop additional
arrangements.

- Pursue additional business development opportunities. The Company
regularly evaluates opportunities to expand its business activities
within the oil service industry, particularly in the seismic sector. For
example, the Company is evaluating a joint venture with a seismic
acquisition company and a seismic data processing company to pursue
multi-client seismic activities in selected areas of North America.
Multi-client seismic data would be acquired and owned by the joint
venture and marketed to numerous oil and gas companies for use in their
exploration and production operations.

RECENT DEVELOPMENTS

In October 1997, the Company entered into a nonbinding letter of intent to
acquire all of the issued and outstanding capital stock of North American
Western Data Services, Inc. ("Western Data"), which leases and sells geophysical
surveying equipment to companies engaged in the seismic services industry. The
total consideration to be paid by the Company is approximately $3 million,
subject to adjustment in certain instances, payable approximately 92% in shares
of Common Stock and 8% in cash. No assurance can be given as to whether the
acquisition of Western Data will be completed. Consummation of the transaction
is subject to satisfactory completion by the Company of its due diligence
review, execution of a definitive agreement and other customary conditions.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

The discussion in this Prospectus contains forward-looking statements that
involve risks and uncertainties. The Company's actual future results could
differ significantly from those discussed herein. Factors that could cause or
contribute to such differences include, but are not limited to, those discussed
in "Prospectus Summary," "Risk Factors," "Management's Discussion and Analysis
of Financial Condition and Results of Operations" and "Business," as well as
those discussed elsewhere in this Prospectus. Statements contained in this
Prospectus that are not historical facts are forward-looking statements that are
subject to the safe harbor created by the Private Securities Litigation Reform
Act of 1995.

RISK FACTORS

In evaluating an investment in the Common Stock being offered hereby,
prospective investors should consider carefully, among other things, the
following risk factors.

POSSIBLE ADVERSE EFFECT OF VOLATILITY OF OIL AND GAS INDUSTRY AND DEMAND FOR
SERVICES

Demand for the Company's services depends upon the level of spending by oil
and gas companies for exploration, production and development activities, as
well as on the number of crews conducting land and transition zone seismic data
acquisition worldwide, and especially in North America. Fluctuations in the
price of oil and gas in response to relatively minor changes in the supply and
demand for oil and gas continue to have a major effect on these activities and
thus, on the demand for the Company's services. Although published industry
sources indicate that the number of seismic crews has decreased in the last five
years, the Company believes that utilization of 3-D seismic equipment has
increased. There can be no assurance of an increased demand for additional 3-D
seismic equipment or as to the level of future demand for the Company's
services. See "Business."

DEPENDENCE UPON ADDITIONAL LEASE CONTRACTS

The Company's seismic equipment leases typically have a term of three to
nine months and provide gross revenues that recover only a portion of the
Company's capital investment. The Company's ability to generate lease revenues
and profits is dependent upon obtaining additional lease contracts after the
termination of an original lease. However, lessees are under no obligation to,
and frequently do not, continue to lease seismic equipment after the expiration
of a lease. Although the Company has been successful in obtaining additional
lease contracts with other lessees after the termination of the original leases,
there can be no assurance that it will continue to do so. The Company's failure
to obtain additional or extended leases beyond the initial term would have a
material adverse effect on its operations and financial condition. See
"Business -- Business and Operations."

DEPENDENCE ON KEY PERSONNEL

The Company's success is dependent on, among other things, the services of
certain key personnel, including specifically Billy F. Mitcham, Jr., the
Chairman of the Board, President and Chief Executive Officer of the Company. Mr.
Mitcham's employment agreement has an initial term through January 15, 2002, and
is automatically extended on a year-to-year basis until terminated by either
party giving 30 days notice prior to the end of the current term (subject to
earlier termination upon certain stated events). The agreement prohibits Mr.
Mitcham from engaging in any business activities that are competitive with the
Company's business and from diverting any of the Company's customers to a
competitor, for two years after the termination of his employment. The Company
has obtained a $1.0 million key employee life insurance policy payable to the
Company in the event of Mr. Mitcham's death. The loss of the services of Mr.
Mitcham could have a material adverse effect on the Company. In particular, the
Exclusive Lease Referral Agreement with I/O (the "I/O Agreement") is terminable
at such time as Mr. Mitcham is no longer the President of the Company and the
Exclusive Equipment Lease Agreement with Sercel is terminable at such time as he
is no longer employed by the Company in a senior management capacity. See
"Management -- Employment Agreement with Billy F. Mitcham, Jr."

CUSTOMER CONCENTRATION AND CREDIT LOSSES

The Company typically leases and sells significant amounts of seismic
equipment to a relatively small number of customers, the composition of which
changes from year to year as leases are initiated and concluded and customers'
equipment needs vary. Therefore, at any one time, a large portion of the
Company's revenues may be derived from a limited number of customers, and its
ability to maintain profitability includes risks associated with the
creditworthiness and profitability of those customers. In the fiscal years ended
January 31, 1995, 1996 and 1997, the single largest customer accounted for
approximately 16%, 18% and 15%, respectively, of the Company's total revenues.
The termination of any large seismic lease could have a material adverse effect
on the Company's operations if the Company does not replace such business on a
timely basis. See "Business -- Customers; Sales and Marketing."

TECHNOLOGICAL OBSOLESCENCE

The Company has a substantial capital investment in seismic data
acquisition equipment. In addition, under the I/O Agreement, the Company is
required to make an additional investment in seismic and other peripheral
equipment. The Company believes that the technology represented by the equipment
in service and that which it is required to purchase from I/O will not become
obsolete prior to the Company's recovery of its initial investment. However,
there can be no assurance that manufacturers of seismic equipment will not
develop alternative systems that would have competitive advantages over seismic
systems now in use, thus having a potentially adverse effect on the Company's
ability to profitably lease its existing seismic equipment. In the past, the
Company has been successful in avoiding material losses caused by technological
obsolescence by selling its older seismic equipment to seismic contractors and
other parties. However, there can be no assurance that the Company will be able
to sell its older seismic equipment in the future. See "Business -- Key Supplier
Agreements."

VULNERABILITY TO WEATHER CONDITIONS AND SEASONAL RESULTS

The first and fourth quarters of the Company's fiscal year have
historically accounted for and are expected to continue to account for a greater
portion of the Company's revenues than do the second and third quarters of its
fiscal year. This seasonality in revenues is primarily due to the increased
seismic survey activity in Canada from October through March, which affects the
Company due to its significant Canadian operations. This seasonal pattern may
cause the Company's results of operations to vary significantly from quarter to
quarter. Accordingly, period to period comparisons are not necessarily
meaningful and should not be relied on as indicative of future results. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Seasonality" and "Business -- Business and Operations -- Seismic
Equipment Leasing."

DEPENDENCE UPON KEY SUPPLIERS

The Company has and relies upon agreements with I/O, Sercel, Pelton, a
manufacturer and supplier of vibrator control electronics, and StrucTec Systems,
L.L.C. ("StrucTec"), a manufacturer of replacement battery packs and battery
chargers, to purchase seismic equipment that the Company leases and sells to its
customers and, to a lesser extent, to receive lease referrals. The termination
of these agreements for any reason, including any failure by the Company to meet
the minimum purchase requirements under the I/O Agreement, could materially
adversely affect the Company's business. While the Company does not anticipate
any difficulty in obtaining seismic equipment from its suppliers based upon past
experience, any such occurrence could have a material adverse effect upon the
Company's business, financial condition and results of operations. See
"Business -- Key Supplier Agreements."

COMPETITION

Competition in the leasing of seismic equipment is fragmented, and the
Company is aware of several companies that engage in seismic equipment leasing.
The Company believes that its competitors, in general, do not have as extensive
a seismic equipment lease pool as does the Company. The Company also believes

8
10

that its competitors do not have similar exclusive lease referral agreements
with suppliers. Competition exists to a lesser extent from seismic data
acquisition firms that may lease equipment that is temporarily idle. Under the
I/O Agreement, I/O and its subsidiary, Global Charter Corporation ("Global")
retain the right to continue to (i) lease channel boxes in certain situations
where the Company and a prospective lessee cannot or do not enter into a lease,
as more fully described in the I/O Agreement; (ii) lease channel boxes with a
purchase option in North and South America; and (iii) lease channel boxes
outside of North and South America.

The Company has several competitors engaged in seismic equipment leasing
and sales, including seismic equipment manufacturers, companies providing
seismic surveys and oil and gas exploration companies that use seismic
equipment, many of which have substantially greater financial resources than the
Company. There are also several smaller competitors who, in the aggregate,
generate significant revenue from the sale of seismic survey equipment. See
"Business -- Key Supplier Agreements."

NO ANTICIPATED DIVIDENDS

The Company has never paid cash dividends on its Common Stock and does not
presently anticipate paying any cash dividends on the Common Stock in the
foreseeable future. In addition, the loan agreement between the Company and its
commercial lender prohibits the payment of dividends. See "Dividend Policy."

POSSIBLE ADVERSE EFFECT OF ANTI-TAKEOVER PROVISIONS; ISSUANCE OF PREFERRED STOCK

Certain provisions of the Company's Articles of Incorporation and the Texas
Business Corporation Act may tend to delay, defer or prevent a potential
unsolicited offer or takeover attempt that is not approved by the Board of
Directors that the Company's shareholders might consider to be in their best
interest, including an attempt that might result in shareholders receiving a
premium over the market price for their shares. Because the Board of Directors
is authorized to issue preferred stock with such preferences and rights as it
determines, it may afford the holders of any series of preferred stock
preferences, rights or voting powers superior to those of the holders of Common
Stock. Although the Company has no shares of preferred stock outstanding and no
present intention to issue any shares of its preferred stock, there can be no
assurance that the Company will not do so in the future. See "Description of
Capital Stock and Other Securities."

LIMITATION ON DIRECTORS' LIABILITY

The Company's Articles of Incorporation provide, as permitted by governing
Texas law, that a director of the Company shall not be personally liable to the
Company or its shareholders for monetary damages for breach of fiduciary duty as
a director, with certain exceptions. These provisions may discourage
shareholders from bringing suit against a director for breach of fiduciary duty
and may reduce the likelihood of derivative litigation brought by shareholders
on behalf of the Company against a director. See "Description of Capital Stock
and Other Securities -- Limitation on Directors' Liability."

USE OF PROCEEDS

The net proceeds to the Company from the sale of the Common Stock being
offered hereby (assuming a public offering price of $30.375 per share and after
deducting underwriting discounts and estimated expenses of the Offering) are
estimated to be approximately $51.1 million, ($59.0 million if the Underwriters'
over-allotment option is exercised in full). The Company will not receive any
proceeds from the sale of shares by the Selling Shareholders. Approximately $27
million of the net proceeds will be used to purchase additional seismic
equipment for the Company's lease pool which the Company has ordered from
manufacturers and for which the Company has obtained future lease commitments.
The remaining net proceeds will be used for working capital and other general
corporate purposes, including additional equipment purchases, and may be used in
a potential investment in a joint venture to conduct multi-client seismic data
acquisition activities. See "Business -- Business Strategy." Pending such
application of the net proceeds of this Offering, the Company will invest the
net proceeds in investment-grade short-term interest-bearing securities.

DIVIDEND POLICY

The Company has not paid any cash dividends on the Common Stock since its
inception, and the Board of Directors does not contemplate the payment of cash
dividends in the foreseeable future. It is the present policy of the Board of
Directors to retain earnings, if any, for use in developing and expanding the
Company's business. In addition, the Company's bank loan agreement prohibits the
payment of dividends without the bank's prior consent. In the future, payment of
dividends by the Company will also depend on the Company's financial condition,
results of operations and such other factors as the Board of Directors may
consider. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion is intended to assist in understanding the
Company's historical financial position at January 31, 1995, 1996 and 1997, and
July 31, 1997, and results of operations and cash flows for each of the three
years in the period ended January 31, 1997 and the unaudited six-month periods
ended July 31, 1996 and 1997. The Company's consolidated historical financial
statements and notes thereto included elsewhere in this Prospectus contain
detailed financial information that should be referred to in conjunction with
the following discussion.

OVERVIEW

The Company leases and sells seismic equipment primarily to seismic data
acquisition companies and oil and gas companies conducting land and transition
zone seismic surveys worldwide. The Company provides short-term leasing of
seismic equipment to meet a customer's requirements and offers maintenance and
support during the lease term. All leases at July 31, 1997 were for a term of
one year or less. Seismic equipment held for lease is carried at cost, net of
accumulated depreciation.

For the years ended January 31, 1995, 1996 and 1997, revenues from foreign
customers totaled $1.8 million, $3.8 million and $6.8 million, respectively.
While most of the Company's transactions with foreign customers are denominated
in United States dollars, some of the Company's transactions with Canadian
customers are denominated in Canadian dollars. The Company has not been subject
to material gains or losses resulting from currency fluctuations and has not
engaged in currency hedging activities.

SEASONALITY

Historically, seismic equipment leasing has been susceptible to weather
patterns in certain geographic regions. There is some seasonality to the
Company's lease revenues from customers operating in Canada, where a significant
percentage of the seismic survey activity occurs in the winter months, from
October through March. During the months in which the weather is warmer, certain
areas are not accessible to trucks, earth vibrators and other heavy equipment
because of the unstable terrain. This seasonal leasing activity by the Company's
Canadian customers has historically resulted in increased lease revenues in the
Company's first and fourth fiscal quarters. See "Business -- Business and
Operations -- Seismic Equipment Leasing."

RESULTS OF OPERATIONS

Six Months Ended July 31, 1997 Compared with Six Months Ended July 31, 1996

Revenues of $16.2 million for the six months ended July 31, 1997 increased
273% over revenues of $4.3 million for the same prior year period. Leasing
services generated revenues of $6.6 million for the six months ended July 31,
1997, a $3.7 million, or 124% increase, compared to leasing revenues for the
same prior year period. This increase reflected additions to the equipment lease
pool throughout fiscal 1997 and the first two quarters of fiscal 1998. Seismic
equipment sales for the six months ended July 31, 1997 were $9.6 million, an
increase of $8.2 million, or 588%, from $1.4 million for the same prior year
period. The increase in sales was due primarily to the exercise of lease
purchase option contracts in the period totaling $7.5 million.

Sublease costs increased by $62,000 and depreciation increased by $1.5
million, or 56% and 140%, respectively, primarily due to an increase in the
equipment lease pool, resulting in an increase in net leasing revenues of $2.1
million.

Gross margins on seismic equipment sales were 19% and 36% for the six
months ended July 31, 1997 and 1996, respectively. Gross margins decreased
substantially in the six months ended July 31, 1997 because the Company sold
primarily newer equipment when customers exercised purchase options on leased
equipment that had only recently been purchased and added to the Company's
equipment lease pool. In the same prior year period and in the past, the Company
sold primarily older, fully depreciated equipment, yielding significantly
greater margins.

13
15

General and administrative expenses increased $544,000, or 70%, for the six
months ended July 31, 1997, as compared to the same prior year period. Although
general and administrative expenses increased due in part to increased personnel
costs and costs associated with the office in Canada, general and administrative
expenses decreased as a percentage of total revenues from 18% to 8% between the
two periods.

The Company's provision for doubtful accounts expense increased to $299,000
for the six months ended July 31, 1997 from $153,000 in the same prior year
period. The increase was a result of additional provisions for the allowance
account in connection with the bankruptcy filing of one of the Company's
customers, Grant Geophysical, Inc. ("Grant"). Provision for doubtful accounts
was 2% of total revenues in the six months ended July 31, 1997, as compared to
4% of total revenues in the same prior year period. As of July 31, 1997, the
Company's allowance for doubtful accounts was $1.7 million. See "-- Liquidity
and Capital Resources."

Net income for the six months ended July 31, 1997 was $2.9 million, which
increased by $2.0 million, or 234%, as compared to the same prior year period.

Fiscal Year Ended January 31, 1997 Compared with Fiscal Year Ended January 31,
1996

Revenues for fiscal 1997 of $14.7 million represented an increase of $7.4
million, or 101%, over fiscal 1996 revenues of $7.3 million. Leasing services
generated revenues of $8.3 million for fiscal 1997, an increase of $3.2 million,
or 62%, as compared to $5.2 million for fiscal 1996. This increase reflected
additions to the equipment lease pool throughout fiscal 1997 to meet lease
demand. Seismic equipment sales for fiscal 1997 were $6.3 million, an increase
of $4.2 million, or 197%, as compared to $2.1 for fiscal 1996. The increase in
sales was due primarily to the exercise of various lease purchase options
throughout the year totaling $3.5 million.

The Company's sublease costs decreased by $48,000, or 19%, and
depreciation, which related primarily to additional equipment available for
lease, increased by $1.8 million, or 134%, resulting in an increase in net
leasing revenues of $1.5 million.

Gross margins on seismic equipment sales were 34% and 49% for fiscal 1997
and 1996, respectively. Gross margins decreased substantially in the fiscal year
ended January 31, 1997 because the Company sold primarily newer equipment when
customers exercised purchase options on leased equipment that had only recently
been purchased and added to the Company's equipment lease pool. In the same
prior year period and in the past, the Company sold primarily older, fully
depreciated equipment, yielding significantly greater margins.

General and administrative expenses increased $464,000, or 35%, in fiscal
1997 as compared to fiscal 1996 and were 12% and 18% of total revenues for
fiscal 1997 and 1996, respectively. This decrease in general and administrative
expenses as a percentage of total revenues was the result of overhead expenses
remaining relatively constant as revenues increased, offset in part by increases
in legal and accounting expenses associated with being a public company.

The Company's provision for doubtful accounts expense increased from
$627,000 in fiscal 1996 to $1.3 million in fiscal 1997. The increase was a
result of additional provisions for the allowance account. Of the increase,
approximately $500,000 was attributable to the bankruptcy filing of Grant.
Provision for doubtful accounts was 9% of total revenues in fiscal 1997 and
fiscal 1996. As of January 31, 1997, the Company's allowance for doubtful
accounts receivable amounted to $1.5 million. See "-- Liquidity and Capital
Resources."

Net income for fiscal 1997 was $2.7 million, which increased by $989,000,
or 58%, as compared to fiscal 1996.

Fiscal Year Ended January 31, 1996 Compared with Fiscal Year Ended January 31,
1995

Revenues for fiscal 1996 of $7.3 million represented an increase of $2.0
million, or 38%, over fiscal 1995 revenues of $5.3 million. Leasing services
generated revenues of $5.2 million for fiscal 1996, an increase of $2.7 million,
or 113%, as compared to fiscal 1995. The majority of this increase was
attributable to additions of

14
16

lease pool equipment throughout fiscal 1996 to meet lease demand. Seismic
equipment sales for the year ended January 31, 1996 were $2.1 million, a
decrease of $725,000, or 25%, from fiscal 1995.

The Company's sublease costs increased by $6,000, or 2%, and depreciation,
which related primarily to equipment available for lease, increased by $968,000,
or 267%, due to the increase in the equipment lease pool, resulting in an
increase in net leasing revenues of $1.8 million.

Gross margins on seismic equipment sales were 49% and 29% for fiscal 1996
and 1995, respectively. The margin for fiscal 1996 was significantly higher
because of a few high-margin transactions related to older more
fully-depreciated equipment.

General and administrative expenses increased $420,000, or 45%, in fiscal
1996 as compared to fiscal 1995 and were 18% and 17% of total revenues for
fiscal 1996 and 1995, respectively. The increase was due primarily to increased
personnel costs and higher legal and accounting expenses associated with being a
public company.

The Company's provision for doubtful accounts increased from $35,000 in
fiscal 1995 to $627,000 in fiscal 1996. The increase reflected the write-off of
amounts due from a leasing customer which became severely past due and were
ultimately settled for $272,000 less than the amounts owed, and additional
allowances provided for amounts due from a second leasing customer with an
outstanding receivable of $459,000 at January 31, 1996, the majority of which
was past due at that date. The latter outstanding receivable was ultimately
collected in full. Provision for doubtful accounts was 9% of total revenues in
fiscal 1996 as compared to 1% of total revenues in fiscal 1995. As of January
31, 1996, the Company's allowance for doubtful accounts receivable amounted to
$347,000.

Net income for fiscal 1996 was $1.7 million, which increased by $713,000,
or 71%, as compared to fiscal 1995.

LIQUIDITY AND CAPITAL RESOURCES

As of July 31, 1997, the Company had net working capital of approximately
$15.7 million and $5.0 million of availability under its bank credit facilities.
Net cash provided by operating activities for the six months ended July 31, 1997
decreased by $3.6 million, as compared to the same prior year period, primarily
as a result of an increase in trade accounts receivable. At July 31, 1997, the
Company had trade receivables of $3.1 million that were more than 90 days past
due, with four customers owing an aggregate of $2.3 million of such amount. As
of such date, the Company's allowance for doubtful accounts was $1.7 million. In
addition, at such date, the Company had receivables due from one customer of
approximately $539,000, $249,000 of which was more than 12 months past due.

As of July 31, 1997, amounts due from Grant totaled $2.4 million, as a
result of the Company's $1.2 million sale to Grant in May 1997 of the seismic
equipment it was previously leasing. Because the profits on the sale of such
equipment have been deferred until payment is actually received, management did
not correspondingly increase its allowance for trade accounts receivable.
Grant's plan of reorganization was approved by the bankruptcy court on September
30, 1997. As of October 31, 1997, the Company had received payments from Grant
totaling $1.2 million, which represents final settlement on the amounts owed the
Company representing post-bankruptcy petition claims of approximately $1.6
million. The Company expects to collect one half of pre-bankruptcy petition
claims, which total approximately $755,000, prior to fiscal year end. The
Company is currently leasing seismic equipment to Grant.

During March 1997, the Company completed a public offering of 3,450,000
shares of Common Stock, of which 2,875,000 shares were sold by the Company and
575,000 shares were sold by selling shareholders. The net proceeds to the
Company from the offering (after deducting underwriting discounts and
commissions and expenses of the offering) were approximately $18.2 million. The
net proceeds were used to purchase additional 3-D seismic data acquisition
equipment, to pay outstanding debt to its commercial lender under a revolving
line of credit and a term loan and for certain other purposes.

15
17

The Company has established a revolving line of credit with Bank One,
Texas, N.A. ("Bank One") of up to $4.0 million (the "Equipment Revolver") to be
used solely for short-term financing of up to 75% of the seismic equipment
purchased by the Company for approved lease/purchase contracts, and a term loan
of $1.0 million (the "Term Loan") to be used solely for long-term financing of
up to 80% of the purchase price of other seismic equipment. Interest on the
Equipment Revolver and the Term Loan accrues at a floating rate of interest
equal to the Base Rate plus 0.5%. Interest on amounts advanced under the
Equipment Revolver is payable monthly, and the principal amount is due six
months after the date of the initial advance; provided, however, that if the
lessee under a lease/purchase contract does not purchase the seismic equipment
subject to the lease, and there has been no default (as defined) under the
lease, then the Company may extend the maturity date for an additional 18 months
(the "Extended Term"). In such event, the principal and interest on the amount
advanced under the Equipment Revolver would be payable in ratable monthly
installments over the Extended Term. Interest on and the principal amount of the
Term Loan are payable in ratable monthly installments over a two-year period
through and including January 1999. At October 31, 1997, the Company had not
drawn any amounts under the Equipment Revolver or the Term Loan.

The Company has obtained a commitment from Bank One to replace the
Equipment Revolver and the Term Loan with a working capital revolving line of
credit of up to $15 million. Interest on advances under the line of credit will
be payable monthly at a variable rate of up to LIBOR plus 2.75% with principal
due two years from the date of the establishment of the line. Advances will be
limited to 80% of eligible accounts receivable and 50% of all eligible lease
pool equipment.

As of October 31, 1997, capital expenditures for fiscal 1998 totaled
approximately $23.2 million. The Company has budgeted capital expenditures of
$18.3 million for the remainder of fiscal 1998 and $43.0 million for fiscal
1999. Included in these budgeted amounts is approximately $27 million of seismic
equipment which the Company has ordered from manufacturers and for which the
Company has obtained future lease commitments. At October 31, 1997, the Company
had satisfied or exceeded the minimum purchase requirements for the period ended
May 1998 under its Exclusive Lease Referral Agreement with Input/Output, Inc.,
and had exceeded the minimum purchase requirements under its Exclusive Lease
Agreement with Sercel. The remaining $4.7 million of seismic equipment required
to be purchased under the I/O Agreement through May 2000 is included in the
Company's fiscal 1998 and 1999 budgeted capital expenditures. See
"Business -- Key Supplier Agreements". Management believes that the net proceeds
of this Offering, cash provided by operations and funds available from its
commercial lender will be sufficient to fund its operations and budgeted capital
expenditures for the remainder of fiscal 1998 and 1999.

BUSINESS

GENERAL

The Company owns a variety of technologically advanced equipment acquired
from the leading seismic manufacturers. The Company's lease pool includes many
types of equipment used in seismic data acquisition, including all components of
land and transition zone seismic data acquisition systems, geophones and cables,
earth vibrators, peripheral equipment and survey and other equipment. A
substantial portion of the Company's lease equipment is provided by two
manufacturers, Input/Output, Inc. and the Sercel subsidiaries of Compagnie
Generale de Geophysique. The Company believes that most of the advanced seismic
data acquisition systems in use worldwide are either I/O or Sercel systems. In
the last two years, the Company has significantly diversified its equipment
lease pool. At October 31, 1997, approximately 51% of the Company's equipment
lease pool, on a cost basis, consisted of advanced digital recording channels,
with the remainder consisting of peripheral and other equipment.

Certain of the Company's leases contain a purchase option, allowing the
customer to apply a portion of the lease payments to the eventual purchase of
the equipment. Additionally, the Company sells a broad range of used seismic
equipment on a worldwide basis and, in certain markets, acts as a sales
representative or distributor for new seismic equipment.

The Company has supply and exclusive lease referral agreements with several
leading seismic equipment manufacturers including I/O, Sercel and Pelton. The
Company believes that these agreements provide it with a significant competitive
advantage. Under these agreements, the Company is the exclusive worldwide short-
term leasing representative for certain products, except in the case of the I/O
Agreement, which limits the

17
19

Company's exclusivity to the Western Hemisphere. Additional agreements exist
with certain of these manufacturers allowing the Company to act as sales
representative or distributor for such manufacturer's products in selected
markets. These agreements have varying terms and expire in 1997 through 2000,
subject to modification or extension. See "-- Key Supplier Agreements."

BUSINESS STRATEGY

- Expand international operations. Historically, the Company's activities
outside North America have consisted of equipment sales, with a limited
amount of leasing activities. In fiscal 1998, the Company's leasing
activities in South America and other international locations have
increased significantly. The Company believes that it will be able to
expand its international leasing activities as its equipment lease pool
expands and as its customers' operations continue to grow in
international markets. The Company receives referrals from Sercel and
other manufacturers on a worldwide basis. The Company believes that its
alliances with manufacturers will help it to further penetrate
international markets, where such manufacturers are well-recognized and
have well-developed business relationships.

SEISMIC TECHNOLOGY AND THE INDUSTRY

Seismic surveys are a principal source of information used by oil and gas
companies to identify geological conditions that are favorable for the
accumulation of oil and gas and to evaluate the potential for successful
drilling, development and production of oil and gas. Seismic technology has been
used by the oil and gas industry since the 1920's and has advanced significantly
with improvements in computing and electronic technologies. In recent years, the
oil and gas industry has significantly expanded its use of 3-D seismic which
provides a more comprehensive subsurface image and is believed to have
contributed to improved drilling success rates, particularly in mature oil and
gas basins such as those in North America. Additionally, 2-D seismic data
continues to be used in many areas where 3-D data acquisition is cost
prohibitive or logistical access is limited.

Oil and gas exploration companies utilize seismic data generated from the
use of digital seismic systems and peripheral equipment in determining optimal
locations for drilling oil and gas wells, in the development of oil and gas
reserves, and in reservoir management for the production of oil and gas. A
complete digital seismic

18
20

data acquisition system generally consists of (i) a central electronics unit
that records and stores digital data ("CEU"), (ii) seismic recording channel
boxes that contain from one to six seismic channels ("channel boxes"), (iii)
geophones, or seismic sensors, (iv) energy sources including dynamite,
compressed air guns or earth vibrators that create the necessary acoustic wave
to be recorded and (v) other peripheral, or accessory, equipment. Peripheral
equipment includes geophysical cables that transmit digital seismic data from
the channel boxes to the CEU, survey equipment, drilling equipment for shot
holes and other equipment.

In seismic data acquisition, an acoustic wave is discharged at or below the
earth's surface through the discharge of compressed air, the detonation of small
explosive charges or the use of vibrators. As the acoustic wave travels through
the earth, portions are reflected by variations in the underlying rock layers
and the reflected energy is captured by the geophones, which are situated at
intervals along paths from the point of acoustical impulse. The resulting
signals are then transmitted to the channel boxes, which convert the reflected
energy wave from analog to digital data and transmit this data via cable to the
CEU. The CEU stores the seismic data on magnetic tape for processing. The
digital data is then input into a specialized seismic processing system that
uses sophisticated computer software programs to enhance the recorded signal and
produce an image of the subsurface strata. By interpreting seismic data, oil and
gas exploration companies create detailed maps of exploration prospects and oil
and gas reservoirs.

In the past, the 2-D seismic survey was the standard data acquisition
technique used to describe geologic formations over a broad area. 2-D seismic
data can be visualized as a single vertical plane of subsurface information.
Data gathered from a 3-D seismic survey is best visualized as a cube of
information that can be sliced into numerous planes, providing different views
of a geologic structure with much higher resolution than is available with
traditional 2-D seismic survey techniques. 3-D seismic surveys require much
larger data acquisition systems. By using a greater number of channels and
flexible configuration, 3-D seismic data provides more extensive and detailed
information regarding the subsurface geology than does 2-D data. As a result,
3-D data allows the geophysicists interpreting the data to more closely select
the optimal location of a prospective drillsite or oil and gas reservoir.

In the exploration and development process, oil and gas companies establish
requirements for seismic data acquisition programs based on their technical
objectives. Because of the expense associated with drilling oil and gas wells,
decisions whether or where to drill are critical to the overall process. Because
3-D seismic data increase drilling success rates and reduce costs, the Company
believes that oil and gas companies are increasingly requiring 3-D seismic
surveys in their activities. As a result of the increasing requirements for this
higher resolution data, which in turn requires additional channels to collect
and transmit the data, seismic data acquisition systems have been expanding in
size during the past several years.

BUSINESS AND OPERATIONS

Seismic Equipment Leasing. The Company typically purchases new and used
seismic equipment for short-term (less than one year) lease to its customers,
which primarily include seismic service companies. After the termination of the
original equipment lease, the Company enters into additional short-term leases
with other customers, often leasing such equipment multiple times until the end
of its useful life or its sale. The Company's equipment leasing services
generally include the lease of the various components of seismic data
acquisition systems and related equipment to meet a customer's job
specifications. Such specifications frequently vary as to the number of required
recording channels, geophones, energy sources (e.g., earth vibrators) and other
equipment. The Company's customers generally lease seismic equipment to meet
shortages of recording channels and related equipment for specific surveys.
Typically, the Company does not lease all of the channel boxes and other
peripheral equipment required for seismic surveys, although it has the
capability to lease equipment for an entire seismic system and, from time to
time, will do so.

The Company currently has an equipment lease pool comprising a total of
approximately 12,000 seismic recording channels (each channel being capable of
electronically converting seismic data from analog to digital format and
transmitting the digital data), and various peripheral equipment such as
geophones, geophysical cables, earth vibrators, survey equipment and other
items. All of the Company's lease pool equipment is manufactured by reading
seismic equipment manufacturers and is widely used in the seismic industry.

The Company's equipment leases generally have terms of three to nine months
and are typically renewable on a month-to-month basis. The Company offers
maintenance of its leased equipment during the lease term for malfunctions due
to failure of material and parts and will provide replacement equipment as
necessary. In addition, the Company provides telephone support services to
answer its lease customers' questions.

The Company's equipment lease rates vary according to an item's expected
useful life, utilization and initial cost. For example, monthly lease rates for
seismic recording channel boxes range between 6% and 8% of the original cost of
the equipment. Lease payments are due and payable on the first day of each month
of the lease term. The lessee must also obtain and keep in force insurance for
the replacement value of the equipment and a specified minimum amount of general
liability and casualty insurance on the leased equipment during the term of the
lease. Before equipment is delivered, the lessee must provide certification that
the Company has been named an additional insured and loss payee on its policies.
The lessee is responsible for all maintenance and repairs of leased equipment
other than those arising from normal wear and tear. All taxes (other than U.S.
federal income taxes) and assessments are the contractual obligation of the
lessee. To the extent foreign taxes are not paid by the lessee, the relevant
foreign taxing authority might seek to collect such taxes from the Company. To
date, no such collection action has been taken against the Company.

A majority of the Company's leasing revenues have historically come from
North American operations. Within North America, a significant portion of the
Company's total revenues are attributable to Canadian operations. Management
believes that the United States and Canada will continue to be the focal points
of the Company's seismic equipment leasing operations for the foreseeable
future, although the Company is pursuing an expanded presence in other
international locations such as South America and the Far East.

Historically, seismic equipment leasing has been susceptible to weather
patterns in certain geographic regions. There is some seasonality to the
Company's lease operations in Canada, where a significant percentage of the
seismic survey activity usually occurs in the winter season, from October
through March. During the months in which the weather is warmer, certain areas
are not accessible to trucks, earth vibrators and other heavy equipment because
of the unstable terrain. In the United States, most of the seismic survey work
is not usually affected by weather. As a result of weather conditions, the
Company attempts to manage its equipment lease pool to meet seasonal demands.
Equipment leased in Canada during the winter months may be moved to the United
States in the warmer months.

20
22

Seismic Equipment Sales. The Company's equipment sales business serves a
diverse base of industry, governmental, university and research customers. The
Company typically buys used equipment for resale and new equipment in response
to specific customer orders. On occasion, the Company will also hold equipment
of third parties and sell such equipment on consignment.

KEY SUPPLIER AGREEMENTS

The I/O Agreement

Under the I/O Agreement, which was originally entered into in February
1994, the Company is the exclusive third-party recipient of requests from I/O
customers and others to lease, on a short-term basis, channel boxes and certain
peripheral equipment in North and South America through May 31, 2000. The
Company may also acquire certain equipment from I/O at favorable prices based
upon the volume of channel boxes purchased. Subject to certain exceptions, I/O
may not recommend or suggest any competitor of the Company as a potential lessor
of I/O 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 inquiries to lease I/O channel boxes from customers desiring
to expand the capacities of their systems on a short-term basis.

A condition of the I/O Agreement is that the Company must purchase an
aggregate of $13.25 million of I/O 3-D channel boxes on or before May 31, 2000
in the following stated installments: (i) by November 30, 1996, at least $3.0
million, (ii) from January 1, 1997 through May 31, 1997, at least $1.25 million
and (iii) 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, at least $3.0
million. As of October 31, 1997, the Company had purchased I/O equipment
totaling $8.6 million under the I/O Agreement, thereby exceeding its purchase
requirements through May 1998.

Under the I/O Agreement, I/O must inform the Company by telephone,
facsimile or letter of the identity of the third party prospective lessee and
the terms, if any, that have been discussed regarding a proposed lease. The
Company may then contact the prospective lessee and negotiate the terms of a
proposed lease of channel boxes. If the Company (i) is unable to lease the
channel boxes due to a shortage in its lease fleet, (ii) cannot agree with a
prospective lessee on the terms of a proposed lease within 72 hours of the
lessee's introduction to the Company or (iii) otherwise chooses not to lease to
a prospective lessee, then I/O may lease channel boxes to the prospective
lessee. I/O has indicated that the 72-hour time period may be extended as long
as the Company and a prospective lessee are engaged in good faith negotiations
and neither of them has terminated such negotiations.

Leases of channel boxes with purchase options are specifically excluded
from the I/O Agreement. Therefore, I/O may continue to enter into leases with
purchase options in North and South America during the term of the I/O
Agreement. I/O may also continue to sell channel boxes during the term of the
I/O Agreement.

The Company primarily purchases new channel boxes from I/O, but from time
to time purchases channel boxes from I/O's existing lease fleet. All of the new
channel boxes purchased from I/O have a warranty which covers, with certain
exceptions, defects in workmanship for six months and defects in materials and
parts for 12 months. Used channel boxes acquired from I/O's existing lease fleet
will be refurbished by I/O and have a warranty which covers, with certain
exceptions, defects in workmanship for three months.

The I/O Agreement is subject to termination by I/O upon the occurrence of
(i) the Company's failure to comply with the terms of the I/O Agreement after
having received written notice of its non-compliance, (ii) the Company's
discontinuance as a going concern, (iii) the Company's default in the payment of
any obligations to I/O after having received notice that payment is due, (iv)
the Company's insolvency or bankruptcy, (v) Billy F. Mitcham, Jr. no longer
owning at least 250,000 shares of Common Stock of the Company, (vi) Billy F.
Mitcham, Jr. no longer remaining as the President of the Company, (vii) any
transfer

21
23

of the I/O agreement by merger, consolidation, or liquidation, or (viii) the
Company's assignment, or attempted assignment of its rights under the agreement.

The Sercel Lease Agreement

In September 1996, the Company entered into the Exclusive Equipment Lease
Agreement with Sercel (the "Sercel Lease Agreement"), under which the Company
acts as Sercel's exclusive worldwide short-term leasing representative and
Sercel must refer to the Company all requests it receives (other than requests
from its affiliates) to lease its 3-D data acquisition equipment and other field
equipment. Subject to the exceptions discussed below, Sercel may not recommend
or suggest any competitor of the Company as a potential lessor of such data
acquisition equipment. In addition, the Company may not engage in financing
leases and leases for a duration of more than one year.

A condition of the Sercel Lease Agreement has that the Company purchase an
aggregate of $10.2 million of Sercel data acquisition and other field equipment
on or before December 31, 1999. At October 31, 1997, the Company had exceeded
its purchase requirements under the Sercel Lease Agreement.

Sercel must inform the Company of the identity of the third party
prospective lessee and the terms, if any, that have been discussed regarding a
proposed lease. If the Company either (i) is unable to lease the Sercel
equipment due to a shortage in its lease fleet, (ii) cannot agree with a
prospective lessee on the terms of a proposed lease within five business days of
the lessee's introduction to the Company, or (iii) otherwise chooses not to
lease to a prospective lessee, then Sercel may lease its equipment to the
prospective lessee.

The agreement is subject to termination by Sercel (i) at any time upon (a)
Sercel's reasonable belief that the Company has violated or intends to violate
the Foreign Corrupt Practices Act of 1977, as amended, (b) the Company's refusal
or inability to certify that it is in compliance with laws applicable to its
activities, (c) the Company's insolvency, voluntary or involuntary bankruptcy,
assignment for the benefit of creditors or discontinuance as a going concern and
(ii) upon 90 days prior written notice if the Company no longer employs Billy F.
Mitcham, Jr. in a senior management capacity.

The Sercel Sales Agreement

Through Mitcham Canada Ltd., the Company's wholly-owned subsidiary formed
in September 1996, the Company entered into the Commercial Representation
Agreement (the "Sercel Sales Agreement") with Georex, Inc. ("Georex"), a
wholly-owned subsidiary of Sercel, under which the Company is Sercel's
designated sales agent in Canada for its data acquisition and other field
equipment through September 19, 1999, subject to earlier termination after
September 20, 1998, on 90 days prior notice. If not sooner terminated, the
agreement will automatically be extended for successive one-year periods after
September 19, 1999. Under the agreement, the Company is entitled to receive a
commission on all Sercel equipment and spare parts sold in Canada.

In connection with the Sercel Sales Agreement and the Sercel Lease
Agreement, in November 1996, the Company established an office in Calgary,
Alberta, Canada to sell, service and lease Sercel equipment and to lease and
service equipment of other manufacturers. The Company is prohibited from selling
certain seismic equipment that competes with Sercel equipment during the term of
the agreement and for six months thereafter, except that the Company may sell
individual components that compete with components of Sercel equipment, such as
I/O channel boxes and Pelton vibrator control electronics, as well as any
seismic equipment previously used in its lease fleet.

The Sercel Sales Agreement is subject to termination by Georex upon (i)
Georex's reasonable belief that the Company has violated or intends to violate
the Foreign Corrupt Practices Act of 1977, as amended, (ii) the Company's
refusal or inability to certify that it is in compliance with laws applicable to
its activities, or (iii) the Company's insolvency, voluntary or involuntary
bankruptcy, assignment for the benefit of creditors or discontinuance as a going
concern.

22
24

Other Agreements

In May 1996, the Company entered into an exclusive lease referral agreement
(the "Pelton Agreement") with Pelton Company, Inc. The Company believes Pelton
is the leading manufacturer and supplier of vibrator control electronics. The
terms of the Pelton Agreement regarding exclusive lease referrals and favorable
prices are substantially similar to those of the I/O Agreement, except that the
Company has the exclusive referral rights with respect to Pelton's vibrator
control electronics worldwide, through December 31, 1997. Thereafter, such
agreement is automatically extended until terminated by either party upon three
months prior written notice.

In October 1997, the Company entered into the Exclusive Lease
Representative and Distributor Agreement with StrucTec (the "StrucTec
Agreement"), which manufactures and distributes replacement batteries and
battery packs for seismic data acquisition equipment of several manufacturers.
Under the StrucTec Agreement, through October 29, 1999, the Company is the
exclusive worldwide short-term leasing representative and distributor of
replacement batteries, battery packs and certain other peripheral equipment
manufactured by StrucTec. The Company is also the exclusive worldwide
distributor of StrucTec products, except that StrucTec may continue to sell its
products to seismic equipment manufacturers.

The Company is also engaged in discussions with other seismic equipment
manufacturers regarding terms pursuant to which the Company would act as an
exclusive lease or sales representative with respect to their equipment.

CUSTOMERS; SALES AND MARKETING

The Company's major lease customers are seismic data acquisition companies
and major and independent oil and gas companies. The Company typically has a
small number of lease customers, the composition of which changes yearly as
leases are negotiated and concluded and equipment needs vary. As of July 31,
1997, the Company had 26 lease customers with active leases of various lengths.
Customers of the Company's used and new seismic equipment sales and service
business include its lease customers, foreign governments, universities,
engineering firms and research organizations worldwide.

The Company participates in both domestic and international trade shows and
expositions to inform the oil and gas industry of its products and services. In
addition to advertising in major geophysical trade journals, direct advertising
in the form of a biannual listing of equipment offerings is mailed to over 3,000
oil and gas industry participants. The Company believes this mailing generates
significant seismic equipment lease and sales revenues. In addition, the Company
advertises its alliances with each of I/O, Sercel and Pelton in several major
geophysical trade journals. The Company also maintains a web site on which it
lists its seismic equipment for sale and lease.

The Company works with a network of representatives in several
international markets, including Europe, the Far East and the Commonwealth of
Independent States. These agents generate equipment sales and, to a lesser
extent, equipment leasing business for the Company and are compensated on a
commission basis. The Company also expends resources in the areas of customer
service, product support and the maintenance of customer relationships. In
November 1996, the Company established an office in Calgary, Alberta, Canada
from which it leases and sells seismic equipment.

COMPETITION

Competition in seismic equipment leasing is fragmented, and the Company is
aware of several companies that engage in seismic equipment leasing. The Company
believes that its competitors, in general, do not have as extensive a seismic
equipment lease pool as does the Company. The Company also believes that its
competitors do not have similar exclusive lease referral agreements with
suppliers. Competition exists to a lesser extent from seismic data acquisition
firms that may lease equipment that is temporarily idle. Under the I/O
Agreement, I/O and its subsidiary, Global Charter Corporation, retain the right
to continue to (i) lease channel boxes in certain situations where the Company
and a prospective lessee cannot or do not enter into a

23
25

lease, as more fully described in the I/O Agreement; (ii) lease channel boxes
with a purchase option in North and South America; and (iii) lease channel boxes
outside of North and South America. Global owns and operates a lease fleet of
rental seismic equipment, including 3-D channel boxes. Global leases seismic
equipment subject to purchase options and arranges the financing for such
leases. The Company does not believe those equipment leases compete with the
Company's seismic equipment leases, as the Company does not typically engage in
lease/purchase arrangements for I/O seismic equipment. See "Risk Factors --
Competition."

The Company competes for seismic equipment leases on the basis of (i) price
and delivery, (ii) availability of both peripheral seismic equipment and
complete data acquisition systems which may be configured to meet a customer's
particular needs, and (iii) length of lease term. The Company competes in the
used equipment sales market with a broad base of seismic equipment owners,
including seismic service companies which use and eventually dispose of seismic
equipment, many of which have substantially greater financial resources than the
Company. The Company believes there is one competitor in the used seismic
equipment sales business that generates comparable revenues from such sales, as
well as numerous, smaller competitors who, in the aggregate, generate
significant revenue from such sales.

SUPPLIERS

The Company has several suppliers of seismic equipment for its lease fleet.
The Company currently acquires the majority of the 3-D channel boxes for its
lease fleet from I/O and Sercel and acquires the majority of its vibrator
control electronics from Pelton. The Company believes that I/O and Sercel
manufacture most of the land-based seismic systems and equipment in use. Other
suppliers of peripheral seismic equipment include OYO Geospace Corporation
(geophones, cables and seismic cameras), Charge-Air Compression Systems
(compressors), Steward Cable (cables), Trace Exploration (seismic vibrators),
Mark Products (geophones and cables) and Mertz, Inc. (seismic vibrators). From
time to time, the Company purchases new and used peripheral seismic equipment
from various other manufacturers. Management believes that its current
relationships with its suppliers are satisfactory.

EMPLOYEES

As of October 31, 1997, the Company had 26 employees, none of whom is
covered by a collective bargaining agreement. Twenty employees are involved in
sales, management and administration and six work in field operations. The
Company considers its employee relations to be satisfactory.

PROPERTIES

The Company owns its corporate office and warehouse facilities in
Huntsville, Texas. Its headquarters facility consists of 25,000 square feet of
office and warehouse space on approximately six acres. The Company also leases
approximately 10,000 square feet of office and warehouse space at its facilities
in Calgary, Alberta, Canada.

LEGAL PROCEEDINGS

The Company is not a party to any legal proceedings.

CERTAIN TRANSACTIONS AND RELATIONSHIPS

Effective September 20, 1993, the Company and Billy F. Mitcham, Jr. entered
into a Voting Agreement (the "Voting Agreement") with Billy F. Mitcham, Sr.,
Paul C. Mitcham and two trusts established for the benefit of Mr. Mitcham, Jr.'s
sons. Under the Voting Agreement, the holders of shares subject thereto have
agreed that Mr. Mitcham, Jr. has the authority to vote an additional 279,490
shares of Common Stock. Mr. Mitcham, Jr. has voting control of an aggregate of
534,490 shares, or 7.1%, of Common Stock, as of October 31, 1997, and will have
voting control of an aggregate of 484,490 shares, or 5.2%, after the Offering.
The Voting Agreement will terminate on the earlier of the agreement of the
parties, the transfer by the parties of their shares or the expiration of 25
years. See "Principal and Selling Shareholders."

Since April 1994, the Company has engaged Billy F. Mitcham, Sr. under a
consulting agreement. Mr. Mitcham, Sr. has been involved in the energy industry
since 1952 and was formerly the owner and the President of Mitcham Associates,
Inc., which was previously engaged in the leasing and sale of seismic equipment.
Mr. Mitcham, Sr. has served as an industry expert and consultant for the Company
since 1987. The agreement calls for monthly payments to Mr. Mitcham, Sr. of
$5,500. The Company paid Mr. Mitcham, Sr. a total of $66,000 under the agreement
in fiscal 1997. The consulting agreement prohibits Mr. Mitcham, Sr. from
providing consulting services to, and from contacting or soliciting in an effort
to provide services to, any competitor of the Company for two years after the
termination of his engagement. The current term of the agreement expires January
31, 1999, subject to earlier termination on the occurrence of certain stated
events, and is renewable for successive one-year terms at the Company's option.
The Company believes Mr. Mitcham, Sr. could successfully compete with the
Company, given his contacts and extensive knowledge of the seismic leasing
industry. For the above reasons, the Company believes the terms of Mr. Mitcham,
Sr.'s consulting agreement are no less favorable than could be obtained from an
unaffiliated third party with similar experience.

DESCRIPTION OF CAPITAL STOCK AND OTHER SECURITIES

The authorized capital stock of the Company consists of 20,000,000 shares
of Common Stock, par value $.01 per share, and 1,000,000 shares of Preferred
Stock, par value $1.00 per share. As of October 31, 1997, there were outstanding
7,510,759 shares of Common Stock, no shares of Preferred Stock, options to
purchase up to 271,880 shares of Common Stock, and warrants to purchase up to
394,113 shares of Common Stock. Upon completion of this Offering, there will be
9,310,759 issued and outstanding shares of Common Stock.

The following description of the Company's capital stock and other
securities and selected provisions of its Amended and Restated Articles of
Incorporation (the "Amended Articles") and Restated Bylaws is a summary and is
qualified in its entirety by the Company's Amended Articles and Restated Bylaws,
copies of which have been filed with the Commission.

COMMON STOCK

Holders of the Common Stock are entitled to one vote per share for the
election of directors and other corporate matters. Holders of Common Stock are
not entitled to cumulative voting rights in connection with the election of
directors. Therefore, the holders of a majority of the shares voting for the
election of directors may elect all the directors. The Amended Articles permit
actions to be taken by the shareholders of the Company without a meeting, by
written consent, including a written consent signed by less than all of the
shareholders of the Company. Section 9.10A of the Texas Business Corporation Act
("TBCA") requires that prompt notice of the taking of any action by shareholders
without a meeting by less than unanimous written consent be given to all
shareholders who did not consent in writing to the action.

Subject to the rights of any outstanding shares of Preferred Stock, the
holders of Common Stock are entitled to dividends in such amounts and at such
times as may be declared by the Board of Directors of the Company out of funds
legally available therefor. Upon liquidation or dissolution, holders of the
Common Stock are entitled to share ratably in all assets remaining available for
distribution to them after payment or provision for all liabilities and any
preferential rights of any Preferred Stock then outstanding. The Common Stock
carries no preemptive rights. All outstanding shares of Common Stock are, and
the shares of Common Stock to be sold by the Company in the Offering will be,
upon payment therefor as contemplated herein, validly issued, fully paid and
nonassessable securities of the Company.

WARRANTS

As of October 31, 1997, there were outstanding warrants to acquire an
aggregate of 394,113 shares of Common Stock at exercise prices from $3.50 to
$28.12 per share, at a weighted average price of $8.75 per share, expiring on
various dates through October 28, 2002.

The warrants contain provisions providing for appropriate adjustment in the
event of any merger, consolidation, recapitalization, reclassification, stock
dividend, stock split or similar transaction. The warrants contain net issuance
provisions permitting the holder thereof to elect to exercise the warrants in
whole or in part and instruct the Company to withhold from the shares issuable
upon exercise a number of shares, valued at the current fair market value on the
date of exercise, to pay the exercise price. Such net exercise provision has the
effect of requiring the Company to issue shares of Common Stock without a
corresponding increase in capital. A net exercise of the warrants will have the
same dilutive effect on the interests of the Company's shareholders as will a
cash exercise.

OPTIONS

As of October 31, 1997, there were outstanding options to acquire an
aggregate of 271,880 shares of Common Stock, 207,130 of which are currently
exercisable. Such options were exercisable at prices ranging from $3.29 per
share to $22 per share, at a weighted average exercise price of $7.88 per share,
expiring on various dates through October 3, 2007.

31

PREFERRED STOCK

The Board of Directors of the Company is empowered, without approval of the
Company's shareholders, to cause shares of Preferred Stock to be issued in one
or more series and to establish the number of shares to be included in each such
series and the designations, preferences, limitations and relative rights,
including voting rights, of the shares of any series. Because the Board of
Directors has the power to establish the preferences and rights of each series,
it may afford the holders of any series of Preferred Stock preferences, powers
and rights, voting or otherwise, senior to the rights of holders of Common
Stock. This includes, among other things, voting rights, conversion privileges,
dividend rates, redemption rights, sinking fund provisions and liquidation
rights which shall be superior to the Common Stock. The issuance of shares of
Preferred Stock could have the effect of delaying or preventing a change in
control of the Company. No shares of Preferred Stock will be outstanding at the
consummation of this Offering, and the Board of Directors has no current plans
to issue any shares of Preferred Stock.

BUSINESS COMBINATION LAW

The Company is subject to Part Thirteen of the TBCA, known as the "Business
Combination Law." The Business Combination Law prohibits certain mergers, sales
of assets, reclassifications and other transactions between shareholders
beneficially owning 20% or more of the outstanding stock of an "issuing public
corporation" (such shareholders being defined as affiliated shareholders) for a
period of three years following the affiliated shareholder acquiring shares
representing 20% or more of the corporation's voting power, unless two-thirds of
the unaffiliated shareholders approve the transactions at a meeting held no
earlier than six months after the shareholder acquires that ownership. However,
the provisions requiring such a vote of shareholders will not apply to any
transaction with an affiliated shareholder if the transaction or the purchase of
shares by the affiliated shareholder is approved by the board of directors
before the affiliated shareholder acquires beneficial ownership of 20% of the
shares or if the affiliated shareholder was an affiliated shareholder prior to
December 31, 1996, and continued as such through the date of the transaction.

An "issuing public corporation" is defined as a corporation organized under
the laws of Texas that has: (i) 100 or more shareholders, (ii) any class or
series of its voting shares registered under the Exchange Act of 1934, as
amended, or similar or successor statute, or (iii) any class or series of its
voting shares qualified for trading in a national market system. The Business
Combination Law also contains an opt-out provision that allows a corporation to
elect out of the statute by adopting a by-law or charter amendment prior to
December 31, 1997, but the Company does not intend to do so.

Under certain circumstances, the Business Combination Law makes it more
difficult for an affiliated shareholder to effect various business combinations
with a corporation for a three-year period. The provisions of the Business
Corporation Law may encourage companies interested in acquiring the Company to
negotiate in advance with the Board of Directors of the Company, since the
shareholder approval requirement would be avoided if a majority of the directors
then approve, before the shareholder becomes an affiliated shareholder, either
the business combination or the transaction that results in the shareholder
becoming an affiliated shareholder.

LIMITATION ON DIRECTORS' LIABILITY

The Amended Articles limit the liability of the Company's directors to the
Company or its shareholders (in their capacity as directors but not in their
capacity as officers) to the fullest extent permitted by Texas law.
Specifically, directors of the Company will not be personally liable for
monetary damages for an act or omission in the director's capacity as a director
except for liability (i) for any breach of the director's duty of loyalty to the
Company or its shareholders; (ii) for acts or omissions not in good faith that
constitute a breach of duty of the director to the Company or that involve
intentional misconduct or a knowing violation of law; (iii) for any transaction
from which the director derived an improper personal benefit; or (iv) an act or
omission for which the liability of the director is expressly provided for by an
applicable statute.

The inclusion in the Company's Amended Articles of the limitation of the
personal liability of the Company's directors to the Company may have the effect
of reducing the likelihood of derivative litigation

30
32

against those directors, and may deter shareholders or management from bringing
a lawsuit against those directors for breach of their duty of care, even though
such an action, if successful, might otherwise have benefitted the Company and
its shareholders.

TRANSFER AGENT AND REGISTRAR

The transfer agent and registrar for the Common Stock is North American
Transfer Co. Its address is 147 West Merrick Road, Freeport, New York 11520.

UNDERWRITING

Subject to the terms and conditions set forth in the Underwriting
Agreement, the Company and the Selling Shareholders have agreed to sell to the
Underwriters named below (the "Underwriters"), for whom Jefferies & Company,
Inc., Rauscher Pierce Refsnes, Inc. and Gaines, Berland Inc. are acting as
representatives (the "Representatives"), and the Underwriters have severally
agreed to purchase the number of shares of Common Stock set forth opposite their
respective names in the table below at the public offering price less the
underwriting discount set forth on the cover page of this Prospectus:

NUMBER OF
UNDERWRITER SHARES
----------- ---------

Jefferies & Company, Inc....................................
Rauscher Pierce Refsnes, Inc................................
Gaines, Berland Inc.........................................

---------
Total............................................. 1,850,000
=========

The Underwriting Agreement provides that the obligation of the Underwriters
to purchase the shares of Common Stock is subject to certain conditions. The
Underwriters are committed to purchase all of the shares of Common Stock offered
(other than those covered by the over-allotment option described below), if any
are purchased.

The Underwriters propose to offer the Common Stock to the public initially
at the public offering price set forth on the cover page of this Prospectus and
to certain dealers at such price less a concession not in excess of $
per share. The Underwriters may allow, and such dealers may reallow, a discount
not in excess of $ per share to certain other dealers. After the public
offering of Common Stock, the public offering price and concessions to selected
dealers and the reallowance to other dealers may be changed by the
Representatives.

The Company has granted the Underwriters an option, exercisable for 30 days
from the date of this Prospectus, to purchase up to 277,500 additional shares of
Common Stock at the public offering price, less the underwriting discount. To
the extent such option is exercised, each Underwriter will become obligated,
subject to certain conditions, to purchase additional shares of Common Stock
proportionate to such Underwriter's initial commitment as indicated in the
preceding table. The Underwriters may exercise such right of purchase only for
the purpose of covering overallotments, if any, made in connection with the
shares of Common Stock.

The Company, the directors and executive officers of the Company and the
Selling Shareholders have agreed not to offer for sale, sell or otherwise
dispose of any shares for Common Stock, or any securities convertible into or
exchangeable for shares of Common Stock, for a period of 180 days from the date
of this Prospectus, without the prior written consent of Jefferies & Company,
Inc. ("Jefferies").

The Representatives have informed the Company and the Selling Shareholders
that they do not expect the Underwriters to confirm sales of shares of Common
Stock offered by this Prospectus to any accounts over which they exercise
discretionary authority.

The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
certain persons participating in the Offering may engage in transactions,
including stabilizing bids, syndicate covering transactions or the imposition of
penalty bids, which may have the effect of stabilizing or maintaining the market
price of the Common Stock at a level above that which might otherwise prevail in
the open market. A "stabilizing bid" is a bid for or the purchase of the Common
Stock on behalf of the Underwriters for the purpose of fixing or maintaining the
price of the Common Stock. A "syndicate covering transaction" is the bid for or
the purchase of the Common Stock on behalf of the Underwriters to reduce a short
position incurred by the Underwriters in connection with the

32
34

Offering. A "penalty bid" is an arrangement permitting the Representatives to
reclaim the selling concession otherwise accruing to an Underwriter or syndicate
member in connection with the Offering if the Common Stock originally sold by
such Underwriter or syndicate member is purchased by the Representatives in a
syndicate covering transaction and has therefore not been effectively placed by
such Underwriter or syndicate member. The Representatives have advised the
Company that such transactions may be effected on the Nasdaq National Market or
otherwise and, if commenced, may be discontinued at any time.

In connection with the Offering, certain Underwriters and selling group
members (if any) who are qualified market makers on The Nasdaq Stock Market may
engage in passive market making transactions in the Common Stock on The Nasdaq
Stock Market in accordance with Rule 103 of Regulation M during the business day
prior to the pricing of the Offering before the commencement of offers or sales
of the Common Stock. Passive market makers must comply with applicable volume
and price limitations and must be identified as such. In general, a passive
market maker must display its bid at a price not in excess of the highest
independent bid for such security, if all independent bids are lowered below the
market maker's bid, however, such bid must then be lowered when certain purchase
limits are exceeded.

The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain civil liabilities that may be incurred in
connection with the Offering, including liabilities under the Securities Act of
1933 (the "Securities Act"), or to contribute to payments the Underwriters may
be required to make in respect thereof.

LEGAL MATTERS

Certain legal matters with respect to the Common Stock offered hereby will
be passed upon for the Company by Norton, Jacobs, Kuhn & McTopy, L.L.P. and for
the Underwriters by Vinson & Elkins L.L.P., Houston, Texas. Carl L. Norton owns
16,000 shares of Common Stock. The Norton Family Trust, of which Carl L. Norton
is a beneficiary, and Sabrina A. McTopy own warrants to acquire an additional
aggregate of 118,230 shares of Common Stock. Carl L. Norton and Sabrina A.
McTopy are partners in Norton, Jacobs, Kuhn & McTopy, L.L.P.

INDEPENDENT AUDITOR'S REPORT

Board of Directors and Shareholders
Mitcham Industries, Inc.
Huntsville, Texas

We have audited the accompanying consolidated balance sheets of Mitcham
Industries, Inc. and Subsidiary as of January 31, 1996 and 1997, and the related
consolidated statements of income, changes in shareholders' equity and cash
flows for each of the years in the three year period ended January 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Mitcham Industries, Inc. and
Subsidiary as of January 31, 1996 and 1997, and the results of their operations
and their cash flows for each of the years in the three year period ended
January 31, 1997, in conformity with generally accepted accounting principles.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(INFORMATION SUBSEQUENT TO JANUARY 31, 1997 IS UNAUDITED)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization -- Mitcham Industries, Inc. (the Company), is a Texas
corporation formed on January 29, 1987. The Company and its wholly-owned
Canadian subsidiary provide full-service equipment leasing, sales and services
to the seismic industry worldwide, primarily in North and South America.

The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned Canadian subsidiary. All intercompany
transactions and balances have been eliminated in consolidation.

Description of leasing arrangements -- The Company leases various types of
seismic equipment to seismic data acquisition companies. All leases at July 31,
1997 are for one year or less. Lease revenue is recognized ratably over the term
of the lease.

Equipment sold on the installment basis -- The Company periodically sells
seismic equipment on an installment basis. The terms of the sale agreements
generally require twelve payments, with two payments due upon delivery of the
equipment and the remaining payments due over the succeeding ten months. To the
extent a down payment equal to at least 16.5% of the sales price is not
received, the gross profit from the sale is deferred until sufficient payments
have been received to warrant full revenue recognition.

Lease/purchase transactions -- The Company periodically leases equipment
with an option to purchase. The percentage of the lease payments that may be
credited towards the purchase price is recorded as deferred revenues until the
customer exercises the option to purchase the equipment; at which time the
transaction is recorded as a sale.

Inventories -- Inventories consist primarily of used seismic equipment
purchased in bulk liquidation sales. Inventories are valued at the lower of cost
or market using the average cost method.

Seismic equipment held for lease -- Seismic equipment held for lease
consists primarily of remote signal conditioners (channel boxes) and peripheral
equipment and is carried at cost, net of accumulated depreciation. Depreciation
is computed on the straight-line method over the estimated useful lives of the
equipment, which is seven years for channel boxes and three to seven years for
other peripheral equipment.

Property and equipment -- Property and equipment is carried at cost, net of
accumulated depreciation. Depreciation is computed on the straight-line method
over the estimated useful lives of the property and equipment. The estimated
useful lives of equipment range from three to seven years. Buildings are
depreciated over 40 years and property improvements over 10 years.

Income taxes -- The Company accounts for its taxes under the liability
method, whereby the Company recognizes on a current and long-term basis,
deferred tax assets and liabilities which represent differences between the
financial and income tax reporting bases of its assets and liabilities.
Historically the Company has paid income taxes on the cash basis of accounting.
Beginning in fiscal 1998, the Company will no longer be eligible to report on
the cash basis of accounting for federal income tax reporting purposes.

Cash equivalents -- For purposes of presenting cash flows, the Company
considers all highly liquid investments with an original maturity of three
months or less to be cash equivalents.

Earnings per share -- Primary earnings per common and common equivalent
share and earnings per common and common equivalent share assuming full dilution
are computed on the weighted average number of shares outstanding adjusted for
the incremental shares attributed to outstanding options and warrants to
purchase common stock.

Use of estimates -- The preparation of the Company's financial statements
in conformity with generally accepted accounting principles requires the
Company's management to make estimates and assumptions that

F-7
43

MITCHAM INDUSTRIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

affect the amounts reported in these financial statements and accompanying
notes. Actual results could differ from these estimates.

Industry concentration -- The Company's revenues are derived from seismic
equipment leased to companies providing seismic acquisition services. The
seismic industry has rapidly expanded its 3-D seismic acquisition capabilities
over the past few years as this technology has gained broader market acceptance
from oil and gas exploration companies. With this expansion, many of the seismic
acquisition companies in North America, while experiencing rapid growth in 3-D
seismic acquisition revenues, have not experienced corresponding increases in
profitability and have become increasingly leveraged. Should the financial
performance of the companies in this industry not improve, the Company could be
exposed to additional credit risk and be subjected to declining demand for its
leasing services.

New accounting pronouncements -- The Financial Accounting Standards Board
(FASB) issued SFAS No. 121 entitled Impairment of Long-Lived Assets. SFAS No.
121, which became effective beginning February 1, 1996, provides that in the
event that facts and circumstances indicate that the cost of operating assets or
other assets may be impaired, an evaluation of recoverability would be
performed. If an evaluation is required, the estimated future undiscounted cash
flows associated with the asset would be compared to the carrying amount of the
asset to determine if a writedown to market value or discounted cash flow is
required. SFAS No. 121 did not have a material impact on its operating results
or financial condition of the Company upon implementation.

The FASB also issued SFAS No. 123, Accounting for Stock Based Compensation,
effective for fiscal years beginning after December 15, 1995. This statement
allows companies to choose to adopt the statement's new rules for accounting for
employee stock-based compensation plans. For those companies which choose not to
adopt the new rules, the statement requires disclosures as to what earnings per
share would have been if the new rules had been adopted. Management adopted the
disclosure requirements of this statement during fiscal 1997. See Note 12 for
further discussion.

The FASB also issued SFAS No. 128, entitled Earnings Per Share, during
February 1997. The new statement, which is effective for financial statements
issued after December 31, 1997, including interim periods, establishes standards
for computing and presenting earnings per share. The new statement requires
retroactive restatement of all prior-period earnings per share data presented.
The Company does not believe the new statement will have a material impact upon
previously presented earnings per share information.

The FASB also issued SFAS No. 130, Reporting Comprehensive Income and SFAS
No. 131, Disclosures About Segments of an Enterprise and Related Information.
SFAS No. 130 establishes standards for reporting and display of comprehensive
income, its components and accumulated balances. Comprehensive income is defined
to include all changes in equity except those resulting from investments by
owners and distributions to owners. Among other disclosures, SFAS No. 130
requires that all items that are required to be recognized under current
accounting standards as components of comprehensive income be reported in a
financial statement that displays with the same prominence as other financial
statements. SFAS No. 131 supersedes SFAS No. 14, Financial Reporting for
Segments of a Business Enterprise. SFAS No. 131 establishes standards on the way
that public companies report financial information about operating segments in
annual financial statements and requires reporting of selected information about
operating segments in interim financial statements issued to the public. It also
establishes standards for disclosures regarding products and services,
geographic areas and major customers. SFAS No. 131 defines operating segments as
components of a company about which separate financial information is available
that is evaluated regularly by the chief operating decision maker in deciding
how to allocate resources and in assessing performance.

SFAS Nos. 130 and 131 are effective for financial statements for periods
beginning after December 15, 1997 and require comparative information for
earlier years to be restated. Because of the recent issuance of these standards,
management has been unable to fully evaluate the impact, if any, the standards
may have on

F-8
44

MITCHAM INDUSTRIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

the future financial statement disclosures. Results of operations and financial
position, however, will be unaffected by implementation of these standards.

Foreign Currency Translation -- All balance sheet accounts of the Canadian
subsidiary are translated at the current exchange rate as of the end of the
accounting period. Income statement items are translated at average currency
exchange rates. The resulting translation adjustment is recorded as a separate
component of shareholders' equity.

Unaudited Interim Information -- The accompanying financial information as
of July 31, 1997 and for the six month periods ended July 31, 1996 and 1997 has
been prepared by the Company, without audit, pursuant to the rules and
regulations of the Securities and Exchange Commission. The financial statements
reflect all adjustments, consisting of normal recurring accruals, which are, in
the opinion of management, necessary to fairly present such information in
accordance with generally accepted accounting principles.

On January 31, 1996, the Company executed a new line of credit with a bank.
The Company may borrow up to $1,000,000 under the line of credit which bears
interest at prime plus 0.5% (9% at January 31, 1997). Advances under the line of
credit are collateralized by accounts receivable and inventory. Borrowings under
the line were limited to 80% of eligible accounts receivable and 50% of eligible
inventory, as defined. This line was replaced by the credit facility discussed
in Note 4.

========== ========== =======

All long-term debt balances outstanding as of March 1997 were paid off with
the proceeds of the offering of common stock discussed in Note 14.

In January 1997, the Company established a second revolving line of credit
for up to $4.0 million (the "Equipment Revolver") to be used solely for
short-term financing of up to 75% of the seismic equipment purchased by the
Company for approved lease/purchase contracts, and a second term loan of $1.0
million (the "Second Term Loan") to be used solely for long-term financing of up
to 80% of the purchase price of other seismic equipment. Interest on the
Equipment Revolver and the Second Term Loan accrues at a floating rate of
interest equal to the bank's rate of interest ("Base Rate") plus 0.5%. Interest
on amounts advanced under the Equipment Revolver is payable monthly, and the
principal amount is due six months after the date of the initial advance;
provided, however, that if the lessee under a lease/purchase contract does not
purchase the seismic equipment subject to the lease, and there has been no
default (as defined) under the lease, then the Company may extend the maturity
date for an additional 18 months (the "Extended Term"). In such event, the
principal amount of and interest on the amount advanced under the Equipment
Revolver would be payable in ratable monthly installments over the Extended
Term. Interest on the principal amount of the Second Term Loan is payable in
ratable monthly installments over a two-year period through and including
January 1999. No advances had been made on either of these two credit facilities
at July 31, 1997. The Company has obtained a commitment from Bank One to replace
the Equipment Revolver and the Term Loan with a working capital revolving line
credit of up to $15 million. Interest on advances under the line of credit will
be payable monthly at a variable LIBOR-based rate with principal due two years
from the date of the establishment of the line. Advances will be limited to 80%
of eligible accounts receivable and 50% of all eligible lease pool equipment.

5. LEASES

The Company leases and subleases seismic equipment to customers under
operating leases with non-cancelable terms of one year or less. These leases are
generally renewable on a month-to-month basis. All taxes (other than U.S.
federal income taxes) and assessments are the contractual responsibility of the
lessee. To the extent the foreign taxes are not paid by the lessee, the relevant
foreign taxing authorities might seek to collect such taxes from the Company.
Under the terms of its lease agreements, any amounts paid by the Company to such
foreign taxing authorities may be billed and collected from the lessee. If the
Company is unable to collect the foreign taxes it paid on behalf of its lessees,
the Company may have foreign tax credits in the amounts paid which could be
applied against its U.S. income tax liability subject to certain limitations.
The Company is not aware of any foreign tax obligations as of July 31, 1997.

The Company leases seismic equipment from others under month-to-month
operating leases. Lease expense incurred by the Company in connection with such
leases amounted to $245,000, $251,000 and $203,000 for the years ended January
31, 1995, 1996 and 1997, respectively, and $111,000 and $173,000 for the six
months ended July 31, 1996 and 1997, respectively.

A summary of the equipment held for lease to others is as follows:

9. CONCENTRATIONS OF CREDIT RISK

As of January 31, 1996 and 1997 and July 31, 1997, amounts due from
customers which exceeded 10% of accounts receivable, amounted to an aggregate of
$1,138,000 from three customers, $1,748,000 from two customers, and $7,288,000
from two customers, respectively.

One of the Company's significant customers filed for bankruptcy protection
during December 1996. Revenues derived from this customer amounted to 15% of
total revenues for the fiscal year ended January 31, 1997. As of that date,
amounts due from this customer totaled approximately $1.2 million. As of January
31, 1997, the Company's allowance for trade accounts receivable was $1.5
million, which amount was intended to fully reserve all amounts due from this
customer and provide for any potential loss associated with the Company's
remaining trade accounts receivable. For the six months ended July 31, 1997,
this customer represented approximately 11% of the Company's revenues. As of
July 31, 1997, amounts due from this customer totaled $2.4 million, an increase
of approximately $1.2 million from the amount this customer owed at January 31,
1997, due to the Company's $1.2 million sale to this customer in May 1997 of the
seismic equipment it was previously leasing. In June 1997, the Company entered
into an agreement with this customer for repayment of the receivable balance
associated with the sale of equipment and post-bankruptcy petition lease
payments due from this customer. The agreement requires bimonthly payments of
$65,000 and allows this customer to receive a discount for prepayment of the
total receivable balance. Through October 1997, the Company has received
payments from this customer totaling $1.2 million, which represents final
settlement on the amounts owed the Company representing post-bankruptcy petition
claims of approximately $1.6 million. The Company expects to collect one-half of
pre-bankruptcy petition claims, which are approximately $755,000 as of July 31,
1997. The Company's allowance for trade accounts receivable balance at July 31,
1997 is $1.7 million, which management believes is adequate to cover any
potential loss associated with this customer and the Company's remaining trade
accounts receivable.

The Company maintains deposits with banks which exceed the Federal Deposit
Insurance Corporation (FDIC) insured limit and has a money market account
included in its cash balances which is not FDIC insured. Management believes the
risk of loss in connection with these accounts is minimal.

10. SHAREHOLDERS' EQUITY

The Company has 1,000,000 shares of preferred stock authorized, none of
which are outstanding as of July 31, 1997. The preferred stock may be issued in
multiple series with various terms, as authorized by the Company's Board of
Directors. The Company has 20,000,000 shares of common stock authorized, of
which 7,380,639 are issued and outstanding as of July 31, 1997. Warrants to
acquire 892,750 shares of the Company's commons stock at $3.50 per share issued
in connection with the Company's 1995 initial public offering were exercised
during fiscal 1997. During March 1997, the Company consummated a public offering
of its common stock, as more fully discussed in Note 14, in which it sold to
underwriters 2,875,000 shares of common stock.

The Company issued warrants to various shareholders during fiscal 1995 to
acquire 49,500 shares of the Company's common stock at $5.00 per share. The
number of shares and exercise price of the warrants were adjusted to 63,953 and
$3.87, respectively, during fiscal 1996 as a result of the anti-dilution
provisions of the warrants. Of these warrants, 49,113 remained unexercised at
July 31, 1997.

In July 1995, the Company issued warrants to acquire 35,000 shares of its
common stock to a public relations firm engaged by the Company. The warrants are
exercisable at $3.50 per share for a period of five years from their issuance
and are unexercised at July 31, 1997.

In January 1995, the Company issued warrants to acquire 85,000 units
(consisting of two shares of common stock and one warrant to purchase one share
of common stock at $4.20 per share) at $7.97 per unit to underwriters in
connection with the Company's initial public offering. The securities underlying
these

F-13

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

warrants, as well as the common stock underlying currently outstanding warrants,
are subject to certain piggy-back registration rights. As of July 31, 1997,
13,000 of these warrants remained unexercised.

In exchange for services in 1996, the Company issued warrants to its legal
counsel. In August 1996, the Company issued warrants to purchase 50,000 shares
of its common stock for $6.43 per share, exercisable for a period of four years
from issuance. Warrants to acquire 40,000 shares are unexercised at July 31,
1997. In December 1996, the Company issued warrants to purchase 50,000 shares of
its common stock at $9.28 per share, exercisable beginning December 14, 1997 for
a period of four years from their issuance. These 50,000 warrants are
unexercised at July 31, 1997.

Warrants to acquire 200,000 shares of the Company's common stock were
issued to underwriters in connection with the Company's secondary offering in
March 1997. The warrants are exercisable at $8.40 per share for a period of two
years from their issuance and are unexercised at July 31, 1997.

11. COMMITMENTS AND CONTINGENCIES

Equipment purchases -- On February 22, 1994, the Company executed an
agreement with Input/Output, Inc. (I/O) under which I/O will notify the Company
of any inquiries it receives to lease I/O's channel boxes and other peripheral
equipment in North and South America and will allow the Company the opportunity
to provide such leasing. In the event the Company and a prospective customer are
unable to reach agreement on such leases in a 72-hour period, I/O shall have the
right to offer the equipment for lease to the prospective customer. Effective
June 1, 1996, the Company entered into an agreement with I/O to amend the terms
of and extend the Exclusive lease Referral Agreement through May 31, 2000. Under
the I/O Agreement as amended, the Company must purchase an aggregate of $13.25
million of I/O equipment as follows: $3.0 million of I/O equipment between June
1 and November 30, 1996 (the "Renewal purchase"), with a minimum of $1.5 million
to be purchased by August 31, 1996. Thereafter, 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 each of the years from June 1, 1997 through May 31, 1997, 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 (of an aggregate
additional $10.25 million after the $3.0 million Renewal Purchase is made). As
of July 31, 1997, the Company believes it has fulfilled the terms of the
agreement, including the minimum purchase commitments through such date.

In September 1996, the Company entered into two agreements with the Sercel
subsidiaries of Compagnie Generale de Geophysique ("Sercel"). One agreement, the
Exclusive Equipment Lease Agreement provides that until December 31, 1999, the
Company will be Sercel's short-term leasing representative throughout the world
and that Sercel will refer to the Company all requests it receives from its
customers to lease its 3-D data acquisition equipment and other field equipment.
The second agreement, the Commercial Representation Agreement, provides that
until September 19, 1999, subject to certain termination after September 19,
1998, the Company will be Sercel's exclusive sales agent in Canada. In
connection with entering into this agreement, the Company established an office
in Calgary, Alberta, Canada in November 1996. As of July 31, 1997, the Company
believes it has fulfilled the terms of the agreement, including the minimum
purchase commitments.

These agreements are subject to termination under certain circumstances
including, among others, non-payment of amounts due, insolvency of the Company,
and the current President of the Company no longer being employed.

Employment Agreement -- Effective January 15, 1997, the Company entered
into an employment agreement with the Company's President for a term of five
years, beginning January 15, 1997, which term is automatically extended for
successive one-year periods unless either party gives written notice of
termination at least 30 days prior to the end of the current term. The agreement
provides for an annual salary of $150,000, subject to increase by the Board of
Directors. It may be terminated prior to the end of the initial term or any

F-14

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

extension thereof if the President dies; if it is determined that the President
has become disabled; if the Board of Directors determines that the President has
breached the employment agreement in any material respect, has appropriated a
material business opportunity of the Company or has engaged in fraud or
dishonesty with respect to the Company's business that is punishable by
imprisonment. If the President's employment is terminated by the Company prior
to the end of the initial five-year term other than for a reason enumerated
above, the President will be entitled to payments equal to $450,000, payable
ratably over the 24 months following such termination. For a period of two years
after the termination of the agreement, the President is prohibited from
engaging in any business activities that are competitive with the Company's
business and from diverting any of the Company's customers to a competitor.

Consulting agreements -- The Company has a contract with the father of the
Company's President, to provide sales consulting services. The agreement calls
for payments of $5,500 per month through April 1999, subject to earlier
termination on the occurrence of certain events.

12. STOCK OPTION PLANS

The Company has a stock option plan under which options to purchase a
maximum of 400,000 shares of common stock may be issued to officers, employee
directors, key employees and consultants of the Company. The stock option plan
provides both for the grant of options intended to qualify as "incentive stock
options" under the Internal Revenue Code of 1986, as amended (the Code), as well
as options that do not so qualify.

Activity in the 1994 Stock Option Plan and Director Plan (as defined
below), collectively referred to as the Plans, for the years ended January 31,
1996 and 1997 and the six months ended July 31, 1997 was as follows:

As of July 31, 1997, options to acquire 291,250 shares of the Company's
common stock were fully vested and exercisable at a weighted average exercise
price of $4.74 per share. The remaining options which have a weighted average
exercise price of $11.13 per share, will vest in fiscal 1999.

F-15

MITCHAM INDUSTRIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

If not previously exercised, options outstanding at July 31, 1997, will
expire as follows: 161,750 options expire on May 9, 1999; 9,000 options expire
on December 4, 2000; 9,000 options expire on August 14, 2001; 21,500 options
expire on May 9, 2004; 2,000 options expire on March 16, 2005; 3,000 options
expire on June 8, 2005; 51,000 options expire on December 4, 2005; 3,000 options
expire on June 12, 2006; 31,000 options expire on August 14, 2006, and 3,000
options expire on June 11, 2007.

With respect to incentive stock options, no option may be granted more than
ten years after the effective date of the stock option plan or exercised more
than ten years after the date of grant (five years if the optionee owns more
than 10% of the common stock of the Company at the date of grant). Additionally,
with regard to incentive stock options, the exercise price of the option may not
be less than 100% of the fair market value of the common stock at the date of
grant (110% if the optionee owns more than 10% of the common stock of the
Company). Subject to certain limited exceptions, options may not be exercised
unless, at the time of exercise, the optionee is in the service of the Company.
As of July 31, 1997, options to purchase an aggregate of 294,250 shares of
common stock are issued and outstanding under the Plans, 183,250 of which are
exercisable at a price of $5.00 per share, 60,000 of which are exercisable at
$3.29 per share and 39,000 of which are exercisable at $5.75 per share and 1,000
of which are exercisable at $6.00 per share.

The Company has a non-employee director stock option plan (the Director
Plan) which provides for the grant of options that do not qualify as "incentive
stock options" under the Code. Options granted under the Director Plan must have
an exercise price at least equal to the fair market value of the Company's
common stock on the date of grant. Pursuant to the Director Plan, options to
purchase 1,000 shares of common stock are granted to each non-employee director
upon his election to the Board and every year thereafter so long as he is
re-elected to the Board of Directors. Options granted under the Director Plan
are fully vested one year after their grant and expire ten years after the date
of the grant. As of July 31, 1997, 11,000 options have been granted under this
Plan at exercise prices ranging from $2.88 to $11.13 and none have been
exercised as of July 31, 1997.

The Company applies APB Opinion No. 25, Accounting for Stock Issued to
Employees, and related Interpretations in accounting for its plans. Accordingly,
no compensation cost has been recognized for its stock option plans. Had
compensation expense for the Company's stock-based compensation plans been
determined based on the fair value at the grant dates for awards under those
plans, consistent with the method of SFAS No. 123, the Company's net income and
income per common share would have been decreased to the pro forma amounts
indicated below:

The fair value of each option grant was estimated on the date of grant
using the Black-Scholes option pricing model with the following assumptions;
risk free rates of 5.4% to 7%; volatility of 48.4%; no assumed dividend yield;
and expected lives of five to ten years.

13. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company's financial instruments consist of trade receivables and
payables and notes payable to banks. The Company believes the carrying value of
these financial instruments approximate their estimated fair value.

14. PUBLIC OFFERINGS OF COMMON STOCK

During March 1997, the Company completed a public offering of a total of
3,450,00 shares of its common stock, par value $0.01, of which 2,875,000 shares
were sold by the Company and 575,000 shares were sold by the selling
shareholders. The net proceeds to the Company from the offering (after deducting
underwriting discounts and commissions and estimated expenses of the offering)
were approximately $18.2 million.

The Company is preparing to register with the Securities and Exchange
Commission 1,850,000 shares of its common stock, of which 1,800,000 shares are
being sold by the Company and 50,000 shares are being sold by selling
shareholders. The Company has granted an option to the underwriters to purchase
up to 277,500 shares on the same terms to satisfy over-allotments in the sale of
the 1,850,000 shares.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

Article Nine of the Company's Amended and Restated Articles of
Incorporation (the "Articles") eliminates or limits the personal liability of
directors for damages for an act or omission in the director's capacity as a
director, except for (i) a breach of a director's duty of loyalty to the Company
or its shareholders; (ii) an act or omission not in good faith that constitutes
a breach of duty of the director to the Company or that involves intentional
misconduct or a knowing violation of the law; (iii) a transaction from which a
director received an improper benefit, whether or not the benefit resulted from
an action taken within the scope of the directors' office; or (iv) an act or
omission for which the liability of a director is expressly provided for by an
applicable statute.

Article Eleven of the Articles makes mandatory the indemnification of
directors permitted under Section B of Article 2.02-1 of the Texas Business
Corporation Act ("TBCA") and permits the Company to advance the reasonable
expenses of a director upon compliance with the requirements of Sections K and L
thereof.

Article 2.02-1 of the TBCA provides as follows:

A. In this article:

(1) "Corporation" includes any domestic or foreign predecessor entity
of the corporation in a merger, consolidation, or other transaction in
which the liabilities of the predecessor are transferred to the corporation
by operation of law and in any other transaction in which the corporation
assumes the liabilities of the predecessor but does not specifically
exclude liabilities that are the subject matter of this article.

(2) "Director" means any person who is or was a director of the
corporation and any person who, while a director of the corporation, is or
was serving at the request of the corporation as a director, officer,
partner, venturer, proprietor, trustee, employee, agent, or similar
functionary of another foreign or domestic corporation, partnership, joint
venture, sole proprietorship, trust, employee benefit plan, or other
enterprise.

(3) "Expenses" include court costs and attorneys' fees.

II-1
55

(4) "Official capacity" means

(a) when used with respect to a director, the office of director in
the corporation, and

(b) when used with respect to a person other than a director, the
elective or appointive office in the corporation held by the officer or
the employment or agency relationship undertaken by the employee or
agent in behalf of the corporation, but

(c) in both Paragraphs (a) and (b) does not include service for any
other foreign or domestic corporation or any partnership, joint venture,
sole proprietorship, trust, employee benefit plan, or other enterprise.

(5) "Proceeding" means any threatened, pending, or completed action,
suit, or proceeding, whether civil, criminal, administrative, arbitrative,
or investigative, any appeal in such an action, suit, or proceeding, and
any inquiry or investigation that could lead to such an action, suit, or
proceeding.

B. A corporation may indemnify a person who was, is or is threatened to be
a made a named defendant or respondent in a proceeding because the person is or
was a director only if it is determined in accordance with Section F of this
article that the person:

(1) conducted himself in good faith;

(2) reasonably believed:

(a) in the case of conduct in his official capacity as a director
of the corporation, that his conduct was in the corporation's
best interests; and

(b) in all other cases, that his conduct was at least not opposed
to the corporation's best interests; and

(3) in the case of any criminal proceeding, had no reasonable cause to
believe his conduct was unlawful.

C. Except to the extent permitted by Section E of this article, a director
may not be indemnified under Section B of this article in respect of a
proceeding:

(1) in which the person is found liable on the basis that personal
benefit was improperly received by him, whether or not the benefit resulted
from an action taken in the person's official capacity; or

(2) in which the person is found liable to the corporation.

D. The termination of a proceeding by judgment, order, settlement, or
conviction, or on a plea of nolo contendere or its equivalent is not of itself
determinative that the person did not meet the requirements set forth in Section
B of this article. A person shall be deemed to have been found liable in respect
of any claim, issue or matter only after the person shall have been so adjudged
by a court of competent jurisdiction after exhaustion of all appeals therefrom.

E. A person may be indemnified under Section B of this article against
judgments, penalties (including excise and similar taxes), fines, settlements,
and reasonable expenses actually incurred by the person in connection with the
proceeding; but if the person is found liable to the corporation or is found
liable on the basis that personal benefit was improperly received by the person,
the indemnification (1) is limited to reasonable expenses actually incurred by
the person in connection with the proceeding and (2) shall not be made in
respect of any proceeding in which the person shall have been found liable for
willful or intentional misconduct in the performance of his duty to the
corporation.

F. A determination of indemnification under Section B of this article must
be made:

(1) by a majority vote of a quorum consisting of directors who at the
time of the vote are not named defendants or respondents in the proceeding;

II-2
56

(2) if such a quorum cannot be obtained, by a majority vote of a
committee or the board of directors, designated to act in the matter by a
majority vote of all directors, consisting solely of two or more directors
who at the time of the vote are not named defendants or respondents in the
proceeding;

(3) by special legal counsel selected by the board of directors of a
committee of the board by vote as set forth in Subsection (1) or (2) of
this section, or if such a quorum cannot be obtained and such a committee
cannot be established, by a majority vote of all directors; or

(4) by the shareholders in a vote that excludes the shares held by
directors who are named defendants or respondents in the proceeding.

G. Authorization of indemnification and determination as to reasonableness
of expenses must be made in the same manner as the determination that
indemnification is permissible, except that if the determination that
indemnification is permissible is made by special legal counsel, authorization
of indemnification and determination as to reasonableness of expenses must be
made in the manner specified by Subsection (3) of Section F of this article for
the selection of special legal counsel. A provision obtained in the articles of
incorporation, the bylaws, a resolution of shareholders or directors, or an
agreement that makes mandatory the indemnification permitted under Section B of
this article shall be deemed to constitute authorization of indemnification in
the manner required by this section even though such provision may not have been
adopted or authorized in the same manner as the determination that
indemnification is permissible.

H. A corporation shall indemnify a director against reasonable expenses
incurred by him in connection with a proceeding in which he is a named defendant
or respondent because he is or was a director if he has been wholly successful,
on the merits or otherwise, in the defense of the proceeding.

I. If, in a suit for the indemnification required by Section H of this
article, a court of competent jurisdiction determines that the director is
entitled to indemnification under that section, that court shall order
indemnification and shall award to the director the expenses incurred in
securing the indemnification.

J. If, upon application of a director, a court of competent jurisdiction
determines, after giving any notice the court considers necessary, that the
director is fairly and reasonably entitled to indemnification in view of all the
relevant circumstances, whether or not he has met the requirements set forth in
Section B of this article or has been adjudged liable in the circumstances
described by Section C of this article, the court may order the indemnification
that the court determines is proper and equitable; but if the person is found
liable to the corporation or is found liable on the basis that personal benefit
was improperly received by the person, the indemnification shall be limited to
reasonable expenses actually incurred by the person in connection with the
proceeding.

K. Reasonable expenses incurred by a director who was, is, or is threatened
to be made a named defendant or respondent in a proceeding may be paid or
reimbursed by the corporation, in advance of the final disposition of the
proceeding and without any of the determinations specified in Sections F and G
of this article, after the corporation receives a written affirmation by the
director of his good faith belief that he has met the standard of conduct
necessary for indemnification under this article and a written undertaking by or
on behalf of the director to repay the amount paid or reimbursed if it is
ultimately determined that he has not met that standard or if it is ultimately
determined that indemnification of the director against expenses incurred by him
in connection with that proceeding is prohibited by Section E of this article. A
provision contained in the articles of incorporation, the bylaws, a resolution
of shareholders or directors, or an agreement that makes mandatory the payment
or reimbursement permitted under this section shall be deemed to constitute
authorization of that payment or reimbursement.

L. The written undertaking required by Section K of this article must be an
unlimited general obligation of the director but need not be secured. It may be
accepted without reference to financial ability to make repayment.

M. A provision for a corporation to indemnify or to advance expenses to a
director who was, is or is threatened to be made a named defendant or respondent
in a proceeding, whether contained in the articles of incorporation, the bylaws,
a resolution of shareholders or directors, an agreement, or otherwise, except in

II-3
57

accordance with Section R of this article, is valid only to the extent it is
consistent with this article as limited by the articles of incorporation, if
such a limitation exists.

N. Notwithstanding any other provision of this article, a corporation may
pay or reimburse expenses incurred by a director in connection with his
appearance as a witness or other participation in a proceeding at a time when he
is not a named defendant or respondent in the proceeding.

O. An officer of the corporation shall be indemnified as, and to the same
extent, provided by Sections H, I, and J of this article for a director and is
entitled to seek indemnification under those sections to the same extent as a
director. A corporation may indemnify and advance expenses to an officer,
employee, or agent of the corporation to the same extent that it may indemnify
and advance expenses to directors under this article.

P. A corporation may indemnify and advance expenses to persons who are or
were not officers, employees, or agents of the corporation but who are or were
serving at the request of the corporation as a director, officer, partner,
venturer, proprietor, trustee, employee, agent, or similar functionary of
another foreign or domestic corporation, partnership, joint venture, sole
proprietorship, trust, employee benefit plan, or other enterprise to the same
extent that it may indemnify and advance expenses to directors under this
article.

Q. A corporation may indemnify and advance expenses to an officer,
employee, agent, or person identified in Section P of this article and who is
not a director such further extent, consistent with law, as may be provided by
its articles of incorporation, bylaws, general or specific action of its board
of directors, or contract or as permitted or required by common law.

R. A corporation may purchase and maintain insurance or another arrangement
on behalf of any person who is or was a director, officer, employee, or agent of
the corporation or who is or was serving at the request of the corporation as a
director, officer, partner, venturer, proprietor, trustee, employee, agent, or
similar functionary of another foreign or domestic corporation, partnership,
joint venture, sole proprietorship, trust, employee benefit plan, or other
enterprise, against any liability asserted against him and incurred by him in
such a capacity or arising out of his status as such a person, whether or not
the corporation would have the power to indemnify him against that liability
under this article. If the insurance or other arrangement is with a person or
entity that is not regularly engaged in the business of providing insurance
coverage, the insurance or arrangement may provide for payment of a liability
with respect to which the corporation would not have the power to indemnify the
person only if including coverage for the additional liability has been approved
by the shareholders of the corporation. Without limiting the power of the
corporation to procure or maintain any kind of insurance or other arrangement, a
corporation may, for the benefit of persons indemnified by the corporation, (1)
create a trust fund; (2) establish any form of self-insurance; (3) secure its
indemnity obligation by grant of a security interest or other lien on the assets
of the corporation; or (4) establish a letter of credit, guaranty, or surety
arrangement. The insurance or other arrangement may be procured, maintained, or
established within the corporation or with any insurer or other person deemed
appropriate by the board of directors regardless of whether all or part of the
stock or other securities of the insurer or other person are owned in whole or
part by the corporation. In the absence of fraud, the judgment of the board of
directors as to the terms and conditions of the insurance or other arrangement
and the identity of the insurer or other person participating in an arrangement
shall be conclusive and the insurance or arrangement shall not be voidable and
shall not subject the directors approving the insurance or arrangement to
liability, on any ground, regardless of whether directors participating in the
approval are beneficiaries of the insurance or arrangement.

S. Any indemnification of or advance of expenses to a director in
accordance with this article shall be reported in writing to the shareholders
with or before the notice or waiver of notice of the next shareholders' meeting
or with or before the next submission to shareholders of a consent to action
without a meeting pursuant to Section A, Article 9.10, of this Act and, in any
case, within the 12-month period immediately following the date of the
indemnification or advance.

T. For purposes of this article, the corporation is deemed to have
requested a director to serve an employee benefit plan whenever the performance
by him of his duties to the corporation also imposes duties on or otherwise
involves services by him to the plan or participants or beneficiaries of the
plan. Excise taxes assessed on a director with respect to an employee benefit
plan pursuant to applicable law are deemed fines.

II-4
58

Action taken or omitted by him with respect to an employee benefit plan in the
performance of his duties for a purpose reasonably believed by him to be in the
interest of the participants and beneficiaries of the plan is deemed to be for a
purpose which is not opposed to the best interests of the corporation.

U. The articles of incorporation of a corporation may restrict the
circumstances under which the corporation is required or permitted to indemnify
a person under Section H, I, J, O, P, or Q of this article.

ITEM 17. UNDERTAKINGS.

(a) The undersigned Registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities
Act, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a
form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
(4) or 497(h) under the Securities Act shall be deemed to be part of this
Registration Statement as of the time it was declared effective.

II-5
59

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

(b) 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 Securities and Exchange 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.

(c) The 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 benefits plan's annual report
pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference
in this Registration Statement shall be deemed to be in a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.

EXHIBIT 10.2

EXCLUSIVE LEASE REPRESENTATIVE AND DISTRIBUTOR AGREEMENT

THIS EXCLUSIVE LEASE REPRESENTATIVE AND DISTRIBUTOR AGREEMENT (the
"Agreement") is entered into on this 30th day of October, 1997 (the "Effective
Date") between Mitcham Industries, Inc., a Texas corporation ("Mitcham"), and
StrucTec Systems, L.,L.,C., a limited liability company ("StrucTec"), which
parties agree as follows:

INTRODUCTION. StrucTec manufactures and distributes the equipment listed
on SCHEDULE I ("Products") and the parts listed on SCHEDULE I ("Parts") to
customers in the oil and gas industry. Mitcham leases and sells seismic
equipment to companies in the oil and gas industry. StrucTec now wants to
appoint Mitcham the exclusive lease representative of the Products and
distributor of the Products and Parts and Mitcham wants to accept such
appointments. For good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged for all purposes, Mitcham and StrucTec agree
to the terms set forth herein.

1. APPOINTMENT AS EXCLUSIVE LEASE REPRESENTATIVE OF PRODUCTS AND
DISTRIBUTOR OF PRODUCTS AND PARTS. StrucTec hereby appoints Mitcham as the
exclusive representative for StrucTec to Lease the Products throughout the
world (the "Territory") and Mitcham accepts such appointment. A "Lease" or
"Leasing" means a short-term or long-term lease of Products in the Territory
during the Term (as defined in Section 9), and may include lease/purchases with
special financing. StrucTec hereby also appoints Mitcham as the distributor
for StrucTec to sell the Products and Parts in the Territory and Mitcham
accepts such appointment. Except as set forth in Section 3 below, StrucTec
shall not recommend or suggest any competitor of Mitcham or any other third
party as a source from which Products may be Leased or sold or appoint any
other lease representative for the Products or distributor for the Products and
Parts in the Territory; provided, however, that StrucTec shall have the right
to continue to sell Products and Parts to equipment manufacturers (any OEM) and
Mitcham is prohibited from selling or soliciting the sale of Products and Parts
to the Manufacturers and the Veritas Jackson Office. During the Term of this
Agreement, Mitcham will actively promote and solicit the Leasing and sale of
the Products and Parts.

2. PURCHASE OF PRODUCTS AND PARTS FROM STRUCTEC. Subject to the other
provisions of this Agreement, Mitcham agrees that it will purchase from
StrucTec, and StrucTec agrees that it will sell to Mitcham such Products and
Parts as Mitcham determines it requires to fulfill its obligations hereunder.
StrucTec shall sell to Mitcham such of the Products and Parts as Mitcham shall
order valued after giving effect to the discount(s) set forth on SCHEDULE I.
Mitcham shall receive the applicable discounts set forth on SCHEDULE I attached
hereto with regard to the Products and Parts ordered by Mitcham in each order.
The parties agree that such discounts shall remain in effect throughout the
Term regardless of price changes; provided however, that StrucTec agrees to
give Mitcham 30 days' prior written notice of all price changes on Products and
Parts.

1
2
3. DISCRETION TO LEASE OR SELL IN CERTAIN INSTANCES. Michigan shall have
discretion to accept or reject any potential customer of Products or Parts, as
a result of (a) possessing an insufficient amount of the Products or Parts for
Lease or sale to such third party, (b) reasonably apparent credit risk or any
other reasonable business-related factor, or (c) inability to reach agreement
on the terms of such Lease or sale. Mitcham shall be deemed to have rejected
such a potential customer third party as a result of inability to agree on the
terms of a Lease or sale if Mitcham and the third party are not able to reach
an agreement on such terms within five business days of such third party's
first contact with Mitcham and with regard to the same.

4. PRICING OF PRODUCTS. Neither StrucTec nor Mitcham may require that
the other charge any specific price or follow any pricing guidelines or
establish or require any other specific or general term with regard to the
Leasing or sale of any of the Products, or the provision of any other good or
service by either of them. Notwithstanding the foregoing, Mitcham shall use its
reasonable best efforts to have a reasonable quantity of the Products available
for lease at prices which Mitcham believes reflects the supply of and demand
for the Products, based upon market conditions and forecasted sales.

5. WARRANTY ON PRODUCTS AND PARTS.

5.1. StrucTec warrants to Mitcham all of the Products and Parts sold
by StrucTec to Mitcham as per StrucTec's current standard warranty terms
attached hereto as SCHEDULE 5.1. Such warranty shall be assignable by Mitcham
to any customer, including Lease customers that subsequently buy the Products,
during the period covered by the warranty, StrucTec shall perform all services
and repairs on Products and Parts under warranty at no cost to Mitcham or its
customers.

5.2. The warranty period shall begin from and after the date of first
use of the Products or Parts by a lease customer, but only on the condition
that such use or installation is made within 30 days from the date such Product
or Parts is received by Mitcham.

5.3. Mitcham has no authority whatsoever, express or implied, to make
warranties other than those provided for herein without prior written
permission from StrucTec.

6. TESTING OF PRODUCTS: REPAIRS. Mitcham shall first endeavor to perform
standard maintenance checks of battery packs that are included in the Products
after the termination of a Lease or as otherwise needed, to determine when
repairs are necessary, but may in some cases request that StrucTec perform its
standard maintenance check of Products. In the case of buoys that are included
in the Products, StrucTec will perform its standard maintenance check of such
Products and inform Mitcham of any necessary repairs. Mitcham shall pay $25 for
each of the Products checked by StrucTec, as well as labor costs at a rate of
$45 per hour for StrucTec's repair of any Products that are not covered by
StrucTec's standard warranty, and any reasonable and ordinary freight incurred
by StrucTec with regard to such Products. After such maintenance

2
3
check and any needed repairs, StrucTec shall ship such Products to Mitcham at
Mitcham's expense to a location designated by Mitcham.

7. PURCHASE ORDER ACCEPTANCE AND PAYMENT.

7.1. Mitcham shall confirm with StrucTec all relevant delivery
information before it submits to StrucTec a purchase order for any of the
Products.

7.2. StrucTec shall have the right to reject, in whole or in part,
any purchase order from Mitcham.

7.3. All sales by StrucTec to Mitcham shall be payable in U.S.
dollars on an open 30 day account, said account period to be determined from
the date of shipment from StrucTec.

8. ADVERTISING; TRADE SHOWS. To actively promote and solicit the Leasing
and sale of Products, Mitcham agrees to include the Products by description or
illustration, including the use of photographs, in such of its advertisements in
trade and industry publications as it deems appropriate. Mitcham further agrees
to represent the Products at trade shows, including SEG and others, subject to
StrucTec's obligation to provide Product samples and demonstration units at
StrucTec's actual cost. Mitcham shall obtain StrucTec's prior approval of all
such advertisements and promotional materials.

9. TERM OF AGREEMENT. Unless sooner terminated under Section 16 hereof,
this Agreement shall be effective for a period of two years from and after the
Effective Date (the "Term").

10. RIGHTS TO USE NAME. Mitcham shall have the right during the Term of
this Agreement to (a) identify itself as the exclusive lease representative and
distributor of the Products, and (b) use all StrucTec trademarks and tradenames
related to the Products that Mitcham Leases or sells to third parties in
advertisements and sales and promotional materials; provided, however, all such
StrucTec trademarks and tradenames related to the Products are and shall remain
the sole and exclusive property of StrucTec, and Mitcham shall have no rights
therein other than as specifically set forth in this Agreement.

11. RELATIONSHIP OF THE PARTIES; NO AGENCY. Neither Mitcham nor StrucTec
shall have any authority to control, act for or obligate the other in any way,
except as set forth herein. This Agreement shall not be construed as creating
an agency, partnership or joint venture between Mitcham and StrucTec. Neither
Mitcham nor StrucTec (or any of their employees or representatives) shall be
construed as an agent of the other.

12. INDEMNITY. StrucTec and Mitcham hereby agree to the following
indemnification obligations:

12.1 Mitcham shall indemnify and hold harmless StrucTec, its
directors, officers, employees and affiliates (hereinafter the "StrucTec
Indemnitees") against any and all liability, loss, damages, fines, penalties,
costs and expenses (including, without limitation, court costs and reasonable
attorneys fees) incurred by any of the StrucTec Indemnitees as a result of any
breach or violation by Mitcham or others acting on its behalf of any obligation,
covenant, representation or warranty of Mitcham set forth in this Agreement.

12.2 StrucTec shall indemnify and hold harmless Mitcham, its
directors, officers, employees and affiliates (hereinafter the "Mitcham
Indemnitees") against any and all liability, loss, damages, fines, penalties,
costs and expenses (including, without limitation, court costs and reasonable
attorneys fees) incurred by any of the Mitcham Indemnitees (i) as a result of
any breach or violation by StrucTec or others acting on its behalf of any
obligation, covenant, representation or warranty of StrucTec set forth in this
Agreement, (ii) for infringement or claim of infringement of any claimed patent
rights relating to the Products, of (iii) that arise out of or are based upon
losses, claims, damages or liabilities resulting from the design, manufacture,
and/or operation of any Products, from the failure of any such Products to
satisfy any warranties (whether expressed or implied, if any), or from any
defect in the Products.

12.3 Either party seeking indemnification hereunder shall notify the
other party in writing of any legal action commenced against the StrucTec
Indemnitees or the Mitcham Indemnitees, as the case may be, as soon as
practicable. The Indemnity obligations of Mitcham and StrucTec shall survive the
expiration or termination of this Agreement.

13. Notice.

13.1 The addresses of Mitcham and StrucTec for purposes of giving any
