Notes to Consolidated Financial Statements

1.   Basis of Presentation of Interim Period Statements

     The accompanying financial statements are unaudited and have been prepared
     by SMC Corporation (the "Company") pursuant to the rules and regulations of
     the Securities and Exchange Commission. Certain information and footnote
     disclosures typically included in financial statements prepared in
     accordance with generally accepted accounting principles have been
     condensed or omitted pursuant to such rules and regulations. In the opinion
     of management, the financial statements include all adjustments, consisting
     only of normal recurring adjustments, necessary for a fair presentation of
     the results for the interim periods reported. The financial statements
     should be read in conjunction with the audited financial statements and
     notes thereto included in the 1997 Annual Report on Form 10-K filed with
     the Securities and Exchange Commission. The results of operations for an
     interim period are not necessarily indicative of the results of operations
     for a full year.

2.   Inventories

     Inventories by major classification are as follows (in thousands):


                                           December 31,       March 31,

3.   Earnings Per Share

     The Company adopted FASB Statement 128, "Earnings Per Share," in the fourth
     quarter of 1997. FASB 128 requires dual presentation of basic and diluted
     EPS. Previously, the Company had presented primary EPS. Diluted EPS is
     calculated by dividing net income by the total of the weighted average
     actual shares outstanding for each period plus the number of shares
     calculated as having a dilutive impact, if any, related to the stock
     options under the Company's Stock Incentive Plan, and the warrants issued
     in conjunction with the Company's initial public offering. Previously
     reported amounts for primary EPS are the same as the diluted EPS amounts
     now reported. Basic EPS is computed by dividing the net income by the
     weighted average actual shares outstanding for each period presented with
     no consideration as to the dilutive impact of the Company's outstanding
     stock options or warrants.

4.   Comprehensive Income

     In June 1997, Financial Accounting Standards Board ("FASB") issued
     Statements of Financial Accounting Standards, No. 130, "Reporting
     Comprehensive Income." The Company has adopted the standard as of January
     1, 1998. Total comprehensive income for the three months ended March 31,
     1998 and 1997 was net income of $1.2 million and $916,000, respectively.

     Sales decreased 4.6% to $47.8 million for the first quarter of 1998 from
$50.1 million for the comparable period in 1997. The decrease was largely the
result of a 15.0% unit sales decrease to 381 units, down from 448 in the prior
year. The unit decrease is principally the result of lower than expected sales
during the winter show season.

     Gross profit margin decreased $591,000 (9.0%) in the first quarter of 1998
compared to 1997, and decreased as a percentage of sales from 13.2% to 12.6%.
Gross margin percentage was lower due to the lower sales level and a shift in
the mix to lower priced motor homes, which generally have lower gross margins.

     Selling, general and administrative expenses increased 4.5% to $4.6 million
for the first quarter of 1998 from $4.4 million in the comparable period of
1997.

     Given the factors affecting gross margin and selling, general and
administrative expenses, operating income decreased 35.9% to $1.4 million for
the first quarter of 1998 from $2.2 million in the comparable period of 1997.

     Interest expense decreased 48.7% to $140,000 for the first quarter of 1998
from $273,000 in the comparable period of 1997. The decrease was due to lower
borrowings on the Company's revolving lines of credit during the first quarter
of 1998 compared to 1997. Compared to the first quarter of 1997, lower levels of
finished goods inventory were held in the first quarter of 1998, thus requiring
less borrowing on the Company's line of credit.

     Other income was $176,000 for the first quarter of 1998 compared to $62,000
for the first quarter of 1997.

     For the first quarter of 1998, the effective tax rate was 36.6%, resulting
in an income tax provision of $528,000. For the first quarter of 1997, the
Company's income tax provision was $794,000, at an effective rate of 40%. The
decrease in effective rate is due to the benefit of energy tax credits available
to the Company.

     Net income after tax for the first quarter of 1998 was $916,000, down from
1997's net income of $1.2 million.

     The Company's revenues historically have been subject to some seasonal
fluctuation. Demand for high-line motor coaches tends to increase with the
beginning of the new model year, which occurs during the Company's third quarter
ending September 30.

Liquidity and Capital Resources

     During the first quarter of 1998, SMC generated a negative cash flow from
operations of $367,000 while its working capital position increased from $9.7
million at December 31, 1997 to $12.2 million at March 31, 1998 (including cash
and cash equivalents of $78,000). The Company received proceeds from the
issuance of common stock under its Stock Incentive Plan of $2.0 million during
the first quarter of 1998. These proceeds were used to finance the negative cash
flow from operations in addition to $326,000 in capital expenditures, $982,000
in repayment of short-term and long-term borrowings, and the repurchase of
common stock of $300,000.

     The Company anticipates that its aggregate capital expenditures for 1998
will be approximately $2.0 million. The Company plans to use cash generated from
operations and issuance of long-term debt to fund these expenditures.

     The Company has lines of credit of $10.0 million ($9.0 million of which is
available at March 31, 1998), plus an additional $4.0 million equipment
financing line of credit, which is all available at March 31, 1998. Amounts
outstanding under these lines of credit bear interest at prime (8.5% at March
31, 1998) and are secured by all assets not specifically identified in other
financing obligations. The terms of the revolving credit and equipment financing
agreements require compliance with certain financial covenants and other
covenants. The Company does not believe any of these covenants will have a
material impact on the Company's ability to meet its cash obligations. The
Company was in compliance with all covenants and agreements at March 31, 1998.

     Most dealer purchases of motor coaches from the Company are financed under
flooring financing arrangements between the dealer and a bank or finance
company. Under these flooring arrangements, the financing institution lends the
dealer all or substantially all of the wholesale purchase price of a motor coach
and retains a security interest in the coach

                                       10
<PAGE>
purchased. These financing arrangements provide that, for a period of time after
a coach is financed (generally 12 to 18 months), if the dealer defaults on its
payment or other obligations to the lender, the Company is obligated to
repurchase the dealer's inventory for the amount then due from the dealer plus,
in certain circumstances, costs incurred by the lender in connection with
repossession of the inventory. The repurchase price may be more than the resale
value of the coach. The Company's contingent liability under its repurchase
obligations varies from time to time. As of March 31, 1998, the Company
estimates its total contingent liability under repurchase obligations was
approximately $88.0 million. To date, losses incurred by the Company pursuant to
repurchase obligations have not been material. The Company cannot predict with
certainty its future losses, if any, pursuant to repurchase obligations, and
these amounts may vary materially from the expenditures historically made by the
Company. Furthermore, even in circumstances where losses in connection with
repurchase obligations are not material, a repurchase obligation can represent a
significant cash requirement for the Company.
