ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS.

         (c)  Exhibits. The following exhibit is filed as a part of this report:

                  99    CEO's letter to shareholders distributed to shareholders
                        on June 16, 2003.

ITEM 9.  REGULATION FD DISCLOSURE.

         On June 16, 2003, Mitcham Industries, Inc. distributed to its
shareholders its 2003 Annual Report, the CEO's accompanying letter of which
contains certain forward-looking information regarding industry trends and
increased company revenues beginning in the second fiscal quarter. The text of
the CEO's letter to shareholders is attached to this report as Exhibit 99 and is
incorporated in this report by reference.

"Safe Harbor" Statement under the Private Securities Litigation Reform Act of
1995: The statements contained in this report on Form 8-K are "forward-looking
statements" intended to qualify for the safe harbor from liability established
by the Private Securities Litigation Reform Act of 1995. All statements other
than statements of historical facts included herein, including statements
regarding our future financial position and results of operations, planned
capital expenditures, liquidity and capital resources, business strategy and
other plans and objectives for future operations, the future mix of revenues
from segments and business, commitments and contingent liabilities, and future
demand for our services and predicted improvement in energy industry and seismic
service industry conditions, are forward-looking statements. Actual results may
differ materially from such forward-looking statements. Important factors that
could cause or contribute to such differences include a prolonged and gradual
recovery, or no full recovery, of the energy services sector of a depressed oil
and gas industry, and thereafter, the inherent volatility of oil and gas prices
and the related volatility of demand for the company's services; dependence upon
additional lease contracts; continuing customer concentration and resulting
increased credit risk; continuing industry consolidation; the risk of
technological obsolescence of the company's lease fleet; vulnerability of
seismic activity and demand to weather conditions and seasonality of operating
results; dependence upon few suppliers; and other factors which are disclosed in
the company's most recent report on Form 10-Q.
