SIERRA MONITOR CORPORATION

Notes to the Financial Statements

March 31, 1998

Basis of Presentation

The unaudited financial statements have been prepared by the Company, 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 generally accepted accounting principles have been omitted pursuant to such SEC rules and regulations; nevertheless, the Company believes that the disclosures are adequate to make the information presented not misleading. These financial statements and the notes hereto should be read in conjunction with the financial statements and notes thereto included in the Company's Annual Report on Form 10-KSB for the year ended December 31, 1997 which was filed March 30, 1998. In the opinion of the Company, all adjustments, including normal recurring adjustments necessary to present fairly the financial position of Sierra Monitor Corporation as of March 31, 1998 and the results of its operations and cash flows for the quarter then ended, have been included. The results of operations for the interim period are not necessarily indicative of the results for the full year.

Accounting Policies

There have been no changes in accounting policies used by the Company during the quarter ended March 31, 1998, except as discussed below:

Effective January, 1 1998, the Company adopted the provisions of Statement of Financial Accounting Standards (FASB) No. 130, Reporting of Comprehensive Income. FASB No. 130 establishes standards for the display of comprehensive income and its components in a full set of financial statements. Comprehensive income includes all changes in equity during a period except those resulting from the issuance of shares of stock and distributions to stockholders (shareholders, as applicable). There were no differences between net income (net loss) and comprehensive income (loss) during the quarters ended March 21, 1998 and 1997.

In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information. SFAS No. 131 establishes standards for the way public business enterprises report information about operating segments in annual financial statements and requires those enterprises to report selected information about operating segments in interim financial reports issued to stockholders. SFAS No. 131 is effective for financial statements for periods beginning after December 31, 1997. The Company does not anticipate it will change its reporting methodology as a result of this pronouncement.

Summary of Business

Sierra Monitor Corporation ("SMC" or the "Company") was founded in 1978 to design and develop hazardous gas monitoring devices for protection of personnel and facilities in industrial work places.

Products manufactured by the Company are sold primarily to oil and gas drilling and refining companies, chemical plants, waste-water treatment plants, telecommunications companies, parking garages and landfill rehabilitation projects.

Net Income per share

In 1997,  the Company  adopted SFAS No. 128,  Earnings per Share.  In accordance
with SFAS No. 128,  basic EPS is computed  using the weighted  average number of
common shares outstanding  during the period.  Diluted EPS is computed using the
weighted-average   number  of  common  and  dilutive  common  equivalent  shares
outstanding  during the period.  Dilutive  common  equivalent  shares consist of
common stock  issuable upon  exercise of stock options using the treasury  stock
method.  No adjustments to earnings / (loss) were made for purposes of per share
calculations.  The  following  is a  reconciliation  of the shares  using in the
computation  of basic and diluted EPS for the periods  ending March 31, 1998 and
1997 respectively:
                                                                 1998         1997

ITEM 2: MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations:

For the three months ended March 31, 1998 Sierra Monitor Corporation (the "Company") reported net sales of $1,533,424 compared to $1,146,157 for the three months ended March 31, 1997. The results for the first quarter of 1998 represent a 33.8% increase from the same period in the prior year. Sales increased in each of the Company's product groups including a 44% increase in Sentry systems. The level of sales of Sentry systems, the Company's primary product group, can be influenced by release of orders for construction projects. In the first quarter of 1998 there were two construction projects released, compared to none in the first quarter of 1997.

Gross profit for the three month period ended March 31, 1998 was $964,448 or 62.9% of net sales, compared to $685,854 or 59.8% of net sales, in the same period in the previous year. Labor efficiencies due to the higher sales level contributed to the improved gross margin.

Expenses for research and development, which include new product development and engineering to sustain existing products, were $124,333 for the three month period ended March 31, 1998, compared with $96,923 in the comparable period in 1997. Product development costs in the first quarter of 1998 include outside consulting fees for ongoing development of new products and expanded features of existing products. During the first quarter of 1997, there were no significant new product development projects.

Selling and marketing expenses for the three month period ended March 31, 1998 were $452,387, or 29.5% of net sales, compared to $415,222, or 36.2% of net sales, in the same period in the prior year. As a result of the higher sales level in first quarter of 1998, commissions to independent sales representatives increased by $38,530 over those paid in the first quarter of 1997. There were no other significant changes in selling and marketing expenses.

General and administrative expenses for the first quarter of 1998 were $273,201 or 17.8% of net sales compared to $228,454 or 19.9% in the same period in the prior year. Increases in salary and benefit expenses, depreciation of capital equipment, and professional fees contributed to the higher general and administrative expenses.

Net income for the three month period ended March 31, 1998 was $112,760 or 7.4% of net sales, compared with a net loss of $49,543 or 4.3% of net sales for the same period in the prior year. The higher income is the result of a significant increase in sales combined with improvement in gross margin and lower fixed costs as a percent of sales.

Since the Company generally ships its products in the same month that it receives a purchase order, the Company believes that its backlog at any time is generally not indicative of its level of future business. However, during the three month period ending March 31, 1998 the Company received orders totaling $2,674,165 compared to orders of $1,087,678 in the three month period ending March 31, 1997. As a result of the significant increase in orders in the first quarter, the backlog at the end of the period was $1,612,838, compared to the backlog of $454,296 at December 31, 1997. The Company has increased its inventory and, temporarily, increased its workforce to meet the higher level of demand.

Liquidity and Capital Resources:

During the period ended March 31, 1998, the Company's working capital increased by $101,980 compared to December 31, 1997. At March 31, 1998, cash and cash equivalents and short term investments, totaled $638,767. The short term investments consist of certain Federal Agency Securities

with original maturities greater than 90 days. The Company has not drawn on its line of credit with its commercial bank. The Company believes that its current capital resources are sufficient to support existing and anticipated levels of business.

Future Results:

The Company's future operating results may be affected by a number of factors, including general economic conditions in both foreign and domestic markets, cyclical factors affecting the Company's industry, lack of growth in the Company's end-markets, and the Company's ability to develop, manufacture, and sell both new and existing products at a profitable but competitive price.
