See accompanying notes. 5 MITCHAM INDUSTRIES, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. The consolidated financial statements of Mitcham Industries, Inc. ("the Company") have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with the generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company's latest Annual Report to Shareholders and the Annual Report on Form 10-KSB for the year ended January 31, 1998. In the opinion of the Company, all adjustments, consisting only of normal recurring adjustments, necessary to present fairly the financial position as of April 30, 1998, and the results of operations and cash flows for the three months ended April 30, 1998 and 1997 have been included. 2. On April 23, 1998, a class action lawsuit was filed against the Company and its chief executive officer and chief financial officer in the U.S. District Court for the Southern District of Texas, Houston Division. The complaint, styled STANLEY MOSKOWITZ V. MITCHAM INDUSTRIES, INC., BILLY F. MITCHAM, JR. AND ROBERTO RIOS, alleges violations of Section 10(b) and 20(a) of the Securities Exchange Act of 1934 and Sections 11 and 12(a)(2) of the Securities Act of 1933. The complaint seeks class action status on behalf of those who purchased the Company's common stock from June 4, 1997 through March 26, 1998 and damages in an unspecified amount plus costs and attorney's fees. The complaint alleges materially false and misleading misrepresentations and omissions in public filings and announcements concerning the Company's business and its allowance for doubtful accounts. The Company believes that the plaintiffs' allegations are without merit and that there are meritorious defenses to the allegations, and intends to defend the action vigorously. 3. Effective May 29, 1998, the Company, agreed in principle to the terms of a new Preferred Supplier Agreement with Input/Output, Inc. ("I/O"). The definitive agreement is expected to be signed no later than June 30, 1998, and will replace the parties' Exclusive Lease Referral Agreement. The terms provide that the Company will purchase a minimum of between $90 and $100 million of I/O products over a five year term. In addition I/O will refer rental inquiries from customers worldwide to the Company during the term of the agreement. In a related transaction, I/O sold to the Company, for $15 million a substantial portion of its subsidiary's equipment lease pool, some of which is subject to existing short-term lease agreements. The Company has until June 30, 1998 to purchase the remaining portion of I/O's subsidiary's equipment lease pool, including the assignment of existing short-term lease agreements. I/O has agreed in principle not to lease products covered by the Preferred Supplier Agreement except in limited circumstances. 4. The foregoing interim results are not necessarily indicative of the results of the operations for the full fiscal year ending January 31, 1999. 6 FORWARD-LOOKING STATEMENTS Certain information contained in this Quarterly Report on Form 10-QSB (including statements contained in Part I, Item 2. "Management's Discussion and Analysis or Plan of Operation" and in Part II, Item 1. "Legal Proceedings"), as well as other written and oral statements made or incorporated by reference from time to time by the Company and its representatives in other reports, filings with the Securities and Exchange Commission, press releases, conferences, or otherwise, may be deemed to be forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934. This information includes, without limitation, statements concerning the Company's future financial position and results of operations; planned capital expenditures; business strategy and other plans for future operations; the future mix of revenues and business; contingent liabilities; Year 2000 issues; and future demand and industry conditions. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been correct. When used in this report, the words "anticipate," "believe," "estimate," "expect," "may," and similar expressions, as they relate to the Company and its management, identify forward-looking statements. The actual results of future events described in such forward-looking statements could differ materially from those results which might be anticipated, forecast or estimated by the Company in such forward-looking statements due to risks and uncertainties such as volatility of the oil and gas industry and demand for services; dependence upon additional lease contracts; customer concentration and credit losses; industry consolation; the risk of technical obsolescence of the Company's seismic lease fleet; vulnerability to weather conditions and seasonality of results; dependence upon key suppliers, and other factors (as further described in the Company's Annual Report on Form 10-KSB) and other risks and uncertainties set forth from time to time in the Company's other public reports and public statements. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION 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 April 30, 1998 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, 1997 and 1998, revenues from foreign customers totaled $6.8 million and $17.1 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 7 activity by the Company's Canadian customers has historically resulted in increased lease revenues in the Company's first and fourth fiscal quarters. RESULTS OF OPERATIONS FOR THE THREE MONTH PERIOD ENDED APRIL 30, 1998 AND 1997 Revenues for the three month period ended April 30, 1998 of $15.5 million represented an increase of $9.9 million, or 179%, over the same prior year period revenues of $5.5 million. Short-term leasing services generated revenues of $5.9 million for the three month period ended April 30, 1998, an increase of $1.8 million, or 46%, as compared to $4.0 million for the same prior year period. This increase reflected additions to the equipment lease pool to meet lease demand. Seismic equipment sales for the three month period ended April 30, 1998 were $1.0 million, an increase of $661,000 or 181%, as compared to $365,000 for the same prior year period. The increase in sales was due primarily to customer purchases of lease pool equipment at the end of the lease contract that were not entered into originally as a lease/purchase contract. The Company's customers in several instances preferred to enter into a lease of seismic equipment with an option to purchase at the end of the lease term. Lease services from lease/purchase contracts generated revenues of $1.2 million for the three month period ended April 30, 1998, an increase of $837,000 or 231%, as compared to $363,000 for the same prior year period, and sales from lease/purchase equipment generated revenues of $7.3 million, an increase of $6.6 million or 859%, as compared to $765,000 for the same prior year period. The increase in lease/purchase revenues was due primarily to an increase in customer's demand for lease/purchase option contracts. The Company's leasing revenues from both short-term leasing services and lease/purchase contracts increased by $2.7 million. The Company's sublease costs increased by $229,000, or 545%, and depreciation, which related primarily to equipment available for lease, increased by $1.5 million, or 122%, due to the increase in the equipment lease pool, resulting in an increase in net short-term leasing revenues of $962,000. There were no margins on sales of equipment under lease/purchase agreements for the three month period ended April 30, 1998 and 22% for the prior year period. Gross margins decreased significantly due primarily to one transaction involving leased equipment that had only recently been purchased and added to the Company's equipment lease pool. Gross margins on seismic equipment sales were 44% and 7% for the three month period ended April 30, 1998 and 1997, respectively. Gross margins increased in the fiscal 1998 period because the Company had a few high margin transactions during the quarter. General and administrative expenses increased $723,000, or 123%, for the three month period ended April 30, 1998 as compared to the same prior year period and were 8% and 11% of total revenues, respectively. 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. The Company's provision for doubtful accounts expense increased from $289,000 in the same prior year period to $608,000 for the three month period ended April 30, 1998. The increase was a result of increased business which resulted in an increase in net accounts receivable of 36%. The provision for 8 doubtful accounts expense was 4% of total revenues in for the three month period ended April 30, 1998 and 5% of total revenues in the same prior year period. As of April 30, 1998, the Company's allowance for doubtful accounts was approximately $1.5 million. Net income for the three month period ended April 30, 1998 was $1.7 million, which decreased slightly by $43,000, as compared to the same prior year period. LIQUIDITY AND CAPITAL RESOURCES As of April 30, 1998, the Company had net working capital of approximately $39.9 million and $15.0 million of availability under its bank credit facilities. Net cash provided by operating activities for the three month period ended April 30, 1998 decreased by $8.5 million, as compared to the same prior year period, primarily as a result of an increase in trade accounts receivable and a decrease in accounts payable. At April 30, 1998, the Company had trade accounts receivable of $5.7 million that were more than 90 days past due, with four customers owing an aggregate of $3.4 million of such amount. As of April 30, 1998, the Company's allowance for doubtful accounts was approximately $1.5 million, which management believes is sufficient to cover any losses in its trade accounts receivable, including any losses in its international customers' trade accounts. Although the Company has not received payment on the pre-bankruptcy petition claims from Grant Geophysical, the Company expects to collect one-half of pre-bankruptcy petition claims, which total approximately $755,000. The Company's Chief Financial Officer serves on the creditors' committee. The Company is currently leasing seismic equipment to Grant. Prior to December 8, 1997, the Company had a $5.0 million line of credit with Bank One, Texas, N.A. ("Bank One"). As of December 8, 1997, the Company replaced the previous line of credit with a working capital revolving line of credit of up to $15 million from Bank One (the "New Revolver"). Interest on advances under the New Revolver are payable monthly at a variable rate which is based upon either, at the Company's option, LIBOR or Bank One's base lending rate. The LIBOR rate, if elected, will range between LIBOR plus 1.75% and LIBOR plus 2.75% depending upon the debt service coverage ratio the Company maintains. Similarly, the Bank One base lending rate, if elected, will range between the base rate minus 0.25% and the base rate plus 0.25%, again depending upon the Company's debt service coverage ratio. Additionally, the Company will owe Bank One each fiscal quarter a fee equal of 0.25% of the average daily unused portion of the New Revolver calculated for the previous quarter. Advances will be limited to the total of 80% of eligible accounts receivable and 50% of all eligible lease pool equipment. The New Revolver contains restrictions, among others, on the ability of the Company to incur indebtedness and pay dividends and requires the Company to meet certain financial covenants, including a minimum tangible net worth, a debt service coverage ratio, aging of accounts receivable and net income. The New Revolver will expire on December 8, 1999, at which time the unpaid principal amount of the New Revolver will be due and payable in full. As of April 30, 1998, the Company had not drawn any amounts under the New Revolver. Capital expenditures in the first quarter of fiscal 1999 totaled $5.2 million. As of April 30, 1998, the Company had satisfied all minimum purchase requirements of equipment under both its Exclusive Lease Referral Agreement with Input/Output, Inc. ("I/O") and its Exclusive Equipment Lease Agreement with Sercel. Effective May 29, 1998, the Company entered into an Equipment Purchase Agreeemnt with I/O, pursuant to which the Company purchased a substantial portion of the equipment lease pool of I/O's wholly-owned subsidiary for $15 million, some of which equipment is subject to existing short-term lease agreements. The Company has until June 30, 1998, to 9 purchase the remaining portion of I/O's subsidiary's equipment lease pool, including the assignment of existing short-term lease agreements, at a price to be agreed upon. In a related transaction, the Company and I/O agreed in principle to terms of a new Preferred Supplier Agreement. The definitive agreement is expected to be signed by June 30, 1998, and will replace the parties' Exclusive Lease Referral Agreement. The terms provide that the Company will purchase a minimum of between $90 to $100 million of I/O equipment (after applicable discounts and credits) over a five-year term. In addition, I/O will refer to the Company equipment lease inquiries from its customers worldwide during the term of the Agreement. The new agreement covers all equipment and products currently manufactured and sold by I/O, and, in consideration for the Company's minimum purchase commitments, I/O has agreed that it will not offer more favorable pricing for any other company in the seismic equipment leasing business. Likewise, the Company has agreed that it will not offer for resale to third parties I/O equipment manufactured less than three years from the date of offer, unless such equipment is offered pursuant to the Company's lease/purchase agreements. In the first year of the Preferred Supplier Agreement, the Company is required to purchase a minimum of $30 million of equipment (which includes the $15 million purchase of I/O's subsidiary's lease pool equipment), before applicable discounts and credits. The Company has budgeted capital expenditures of approximately $40 million for fiscal 1999, which includes the above minimum purchase requirements. Management believes that the net proceeds of the December 1997 offering, ($11.4 million remaining) cash provided by operations and funds available from its commercial lender will be sufficient to fund its operations and budgeted capital expenditures for fiscal 1999. YEAR 2000. The Company has begun to address possible remedial efforts in connection with computer software that could be affected by the Year 2000 problem. The Year 2000 problem is the result of computer programs being written using two digits rather than four to define the applicable year. Any programs that have time-sensitive software may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in a major system failure or miscalculations. The Company has been informed by the suppliers of substantially all of the Company's software that all of those suppliers' software that is used by the Company is Year 2000 compliant. The software from these suppliers is used in major areas of the Company's operations such as for financial, sales, warehousing and administrative purposes. The Company has no internally generated software. After reasonable investigation, the Company has not yet identified any Year 2000 problem but will continue to monitor the issue. However, there can be no assurances that Year 2000 problem will not occur with respect to the Company's computer systems. The Year 2000 problem may impact other entities with which the Company transacts business, and the Company cannot predict the effect of the Year 2000 problem on such entities. PART II. OTHER INFORMATION ITEM 1. LEGAL PROCEEDINGS On April 23, 1998, a class action lawsuit was filed against the Company and its chief executive officer and chief financial officer in the U.S. District Court for the Southern District of Texas, Houston Division. The complaint, styled STANLEY MOSKOWITZ V. MITCHAM INDUSTRIES, INC., BILLY F. MITCHAM, JR. AND ROBERTO RIOS, alleges violations of Section 10(b) and 20(a) of the Securities Exchange Act of 1934 and Sections 11 and 12(a)(2) of the Securities Act of 1933. The complaint seeks class action status on behalf of those who purchased the Company's common stock from June 4, 1997 through March 26, 1998 and 10 damages in an unspecified amount plus costs and attorney's fees. The complaint alleges materially false and misleading misrepresentations and omissions in public filings and announcements concerning the Company's business and its allowance for doubtful accounts. The Company believes that the plaintiffs' allegations are without merit and that there are meritorious defenses to the allegations, and intends to defend the action vigorously. ITEM 6.

     Seller are trade secrets and constitute a valuable asset of Seller.  Buyer
     agrees that it shall exercise at least the same degree of care and
     discretion with respect to the hardware and software as it exercises in
     protecting its own confidential information; that it shall not disclose or
     otherwise make available, without the prior written consent of Seller, the
     hardware or software or any copies of it to any other person and that it
     shall not copy or reproduce the hardware or software.  Buyer agrees that
     this provision shall survive the Closing.

          (c)  Buyer further acknowledges that it shall not, without the prior
     written consent of Seller, divulge any information relating to the terms of
     this Agreement to any third party, except as to the extent required by law,
     and shall take all reasonable action to prevent its employees and all
     others, if any, involved in this Agreement from divulging such information
     to third parties.

the Additional Leases actually paid to and received by Seller for the month
in which the Closing (or the Second Closing Date) occurs shall be prorated as
of the Effective Date or the Second Closing Date, as appropriate.  Buyer
shall make a diligent attempt after the Closing to collect any rental
payments delinquent at the time of the assignment of the Leases or Additional
Leases in the usual

                                       5

Seller promptly after receipt by Buyer.  Nothing in this subparagraph shall
prohibit, limit or restrict Seller from collecting or attempting to collect
directly from any lessee in any lawful manner after Closing any rents
delinquent as of Closing.

                                   EXHIBIT A

                                SUMMARY OF TERMS

I/O has proposed to sell its existing rental fleet to Mitcham.  I/O also 
proposes to restructure its existing agreements with Mitcham by entering into 
a new Preferred Supplier Agreement (the "NEW AGREEMENT") with Mitcham (which 
will replace the existing Exclusive Lease Referral Agreement, as amended), on 
the following terms and conditions:

1.   SALE OF RENTAL FLEET.  I/O will sell its rental fleet to Mitcham (including
     Products currently under lease/purchase agreements to I/O's customers) for
     a price to be determined by the parties.  Products currently under
     lease/purchase agreements will be sold subject to such lease/purchase
     agreements, which will be assigned to Mitcham.

2.   MINIMUM ANNUAL PURCHASES.  I/O will agree to sell to Mitcham and Mitcham
     will agree to purchase from I/O, during the Term of the New Agreement,
     certain minimum amounts of new and used I/O Products, as follows:

                                                         
     May 26, 1998 through May 31, 1999  ("YEAR 1")          $30 million
     June 1, 1999 through May 31, 2000  ("YEAR 2")          $25 million
     June 1, 2000 through May 31, 2001  ("YEAR 3")          $25 million
     June 1, 2001 through May 31, 2002  ("YEAR 4")          $25 million
     June 1, 2002 through May 31, 2003  ("YEAR 5")          $25 million
The above amounts shall be based on I/O's list prices for its Products, as published on the date of the New Agreement. Any purchases in excess of the annual minimum aggregate may be applied to purchase commitments for the next year. If Mitcham fails to purchase Products in the minimum amount during any fiscal Year as set forth above, I/O shall have the right to terminate the New Agreement. 3. TERM. Effective as of May 26, 1998 through May 31, 2003. 4. I/O PRODUCTS. "PRODUCTS" covered under the New Agreement will be all products currently manufactured and sold by I/O as of the date of the New Agreement, and shall not refer to any new products introduced and manufactured by I/O after such date; provided, however, that I/O will agree to negotiate with Mitcham for the inclusion of any such new products within the scope of the New Agreement on a case-by-case basis. There will be no territory limitations under the New Agreement. 5. DISCOUNTS AND CREDITS. Mitcham shall be entitled to certain discounts against purchases made pursuant to the terms of the New Agreement. The discount to which Mitcham will be entitled for each Product type purchased will be as set forth on SCHEDULE A. In addition, if Mitcham achieves the minimum annual purchase levels set forth above during each Year, Mitcham shall be entitled to a credit against the purchase price for future purchases of Products in the amount of 10% of the purchase price of Products purchased during that fiscal Year. The credit must be used during the next fiscal Year or it will be waived. Fifty percent (50%) of Products purchased with the credit will count toward Mitcham's minimum annual purchase requirements for that fiscal Year. 9 6. RENTAL RESTRICTIONS. I/O will not offer to rent Products to third parties during the Term, without the express written consent of Mitcham; provided, however, Seller shall have the right to rent Products to third parties for experimental or developmental purposes. I/O agrees to refer rental inquiries for Products to Mitcham during the Term of the New Agreement. Mitcham agrees to use best efforts to promote I/O Products during the term of the New Agreement. 7. RESALE RESTRICTIONS. The parties understand and agree that Mitcham is in the business of leasing Products to its rental customers, and is not acquiring Products for resale to third parties. As part of the consideration for the discounts and credits being granted to Mitcham, Mitcham agrees that it will not offer for resale to third parties, without the prior written consent of I/O, any Products (other than Products that are purchased by Mitcham's rental customers pursuant to purchase options granted under rental agreements) that it has purchased from I/O that were manufactured less than 3 years from the date of the offer. 8. PAYMENT TERMS. Payment of the purchase price for Products shall be net 30 days; provided, however, that Mitcham will be entitled to an additional 2% discount from the purchase price if payment thereof is received by I/O within 10 days from date of shipment. In addition, if Products purchased at any one time have a purchase price of $5 million or more, Mitcham will grant to I/O a purchase money security interest in those Products to secure payment of the purchase price thereof. Mitcham agrees to execute all financing statements required by I/O to perfect its security interests at the time of sale. 9. RIGHT OF FIRST REFUSAL. Mitcham shall grant to I/O a right of first refusal to purchase any Products (other than Products that are proposed to be purchased from Mitcham pursuant to a lease/purchase agreement with one of Mitcham's customers) that Mitcham desires to sell (subject to the resale restrictions), but only with respect to Products for which the sale price exceeds $1 million. I/O shall have the right to match any bona fide third party offer to purchase those Products on the same terms and conditions. 10. TRAINING; MAINTENANCE AND REPAIRS. I/O will offer training courses for Mitcham, and its employees and representatives of customers that lease Products from Mitcham, at a 25% discount to I/O published rates for those services. I/O will provide maintenance and repairs to all Products, at I/O published rates. 11. WARRANTIES. I/O will warrant all new Products based upon I/O's standard limited warranty, as the same is revised from time to time. A limited 90-day warranty will be given on used Products sold to Mitcham. 12. PRESS RELEASES. Neither party will issue any public announcement or press release regarding the New Agreement or any purchase of Products thereunder without the written approval of the other party. 13. PREFERRED PRICING. In consideration for Mitcham's commitment to make the minimum annual purchases described above, I/O agrees that it will not, during the Term, offer pricing for Products to any other customer that is in the same line of business as Mitcham (i.e., seismic equipment rentals) that is more favorable than that offered to Mitcham under the New Agreement. 10 SCHEDULE A to Exhibit A -- Summary of Terms DISCOUNT SCHEDULE - ------------------------------------------------------------------------------- PRODUCT DISCOUNT - ------------------------------------------------------------------------------- MRX Electronics 25% - ------------------------------------------------------------------------------- RSR Electronics 15% - ------------------------------------------------------------------------------- MSX Electronics 10% - ------------------------------------------------------------------------------- Cables 15% - ------------------------------------------------------------------------------- Geophone and Hydrophone Products 15% - ------------------------------------------------------------------------------- Sleeve Guns 10% - ------------------------------------------------------------------------------- Vibrators Negotiated on a case by case basis - -------------------------------------------------------------------------------
