                                     PART I


Item 1.       Description of Business.


      Sierra Monitor Corporation ("SMC" or the "Company") was founded in 1978 to
design and  develop  hazardous  gas  monitoring  devices for the  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.

      Because all of the Company's products are marketed to all such industries,
the Company considers that these are one business segment.  Substantially all of
the  revenues  reported  in part II Item 6 are  attributable  to  sales  to that
segment.

      The Company  designs,  manufactures  and  markets  products  which  detect
combustible  and toxic gases for the  protection  of personnel  and  facilities.
Gases which create a hazard to people and facilities are those  manufactured  or
that occur naturally in a wide variety of locations in the workplace, commercial
areas and homes.  Although the need to monitor gases at very low  concentrations
has been  recognized for many years in industries  such as mining,  the need for
monitoring  devices  continues to expand as more hazards are  identified  and as
more  stringent  government  regulations  have been passed.  The  motivation for
installation  of gas  detection  devices  is driven by  Occupational  Safety and
Health  Administration  (OSHA),  state and  local  governing  bodies,  insurance
companies and industry safety professionals.

      Gas monitoring  instruments are usually  categorized for fixed or portable
applications.  Most  manufacturers  tend  to  specialize  in only  one of  these
categories  because  manufacturing  methods are  different  and the  channels of
distribution  are  different.  The Company  participates  primarily in the fixed
installation market which characteristically requires higher levels of technical
capability to develop and sell the products.

      The Company  capitalizes on its expertise in microprocessor  based control
hardware  to develop  products  which  incorporate  functions  not found in many
competitive instruments. In this respect, the Company markets products under the
concept of "Gas Risk Management".  Gas Risk Management utilizes features such as
recorded event  information,  and graphical  displays on central  computers,  to
allow users to identify  hazards and problems  before they evolve into incidents
which, at a minimum, could cause production delays,  evacuation of personnel and
potentially even damage and injury.

      In addition to gas detection devices, the Company  manufacturers a line of
products known as Industrial  Communication  Bridges (Bridges).  Many industrial
instruments,  such as  programmable  logic  controllers  and various  analytical
systems,  communicate in different,  non-standard,  protocols. Bridges provide a
means for reading and writing data into these devices  using a common,  standard
protocol.  In  1998,  revenue  from  Bridge  products  was  less  than 5% of the
Company's sales.

      The  Company  maintains  research  and  development  programs  to  enhance
existing  products  and to develop new  products.  During the last three  fiscal
years, the research and development expenses, which include costs for sustaining
engineering,  have averaged  approximately  8% of sales.  In 1997,  research and
development  expenses totaled $423,058 compared to $439,017 in 1996 and $406,278
in 1995.

      The Company's products are sold through a network of sales representatives
managed by regional managers. There are currently 30 authorized  representatives
with a total of 38 sales  offices  in the United  States.  The  majority  of the
Company's  representatives  have exclusive  territories and the sales agreements


                                       1
<PAGE>

with each representative  restricts them from representing  competing lines. The
Company's  internal sales organization  includes a Sales Manager,  four Regional
Sales Managers,  an Inside Sales Manager and support  personnel.  In addition to
its primary  factory and office  facility in California,  the Company  maintains
regional sales offices in Illinois, Pennsylvania and Texas.

      At December  31,  1997,  the Company had 34  employees,  of whom 5 were in
research and  development;  10 were in marketing,  sales and service;  3 were in
general  administration;  and 16 were in operations and  manufacturing.  At that
date, 31 of the Company's employees were located in Milpitas,  California, 1 was
located in Chicago, Illinois, 1 was located in Philadelphia, Pennsylvania, and 1
was located in Houston,  Texas. None of the Company's  employees are represented
by a labor union. The Company believes that its relationship  with its employees
is satisfactory.

      The demand for gas monitoring instruments is not seasonal and there are no
customers  to whom sales  exceed 10% of total  annual  sales.  Within the market
sector,  the  telecommunications  industry and the  petrochemical  industry each
account  for up to  approximately  20% of the  Company's  sales  and,  as  such,
economic  factors or labor  problems in those  industries  could affect  Company
sales to those industries.

      The  commercial  order backlog for the Company's  products at December 31,
1997 was $454,296  compared  with  $539,694 at December  31,  1996.  The backlog
includes orders for which the Company has not yet received  engineering  release
from the customer.  Since the Company  generally  ships its products  within the
same month that it receives a purchase  order and  engineering  release from the
customer  for such  products,  the  Company  believes  that its  backlog  at any
particular time is generally not indicative of the level of future sales.

      Representatives  in foreign  countries have various  agreements to promote
the Company's products but no formal international  marketing program exists. In
both 1996 and 1997, sales to international customers were less than 10% of total
sales in each year. The Company has no assets in any foreign countries.

      The gas detection and monitoring industry is highly  competitive.  Most of
the   Company's   competitors   have  far  greater   financial,   marketing  and
manufacturing  resources than the Company by virtue of their  relationships with
larger companies as divisions or subsidiaries. The principal competitive factors
in the industry are reliability,  ease of use,  product support,  and price. The
Company's  products  compete with systems  offered by Bacharach  Inc.,  Detector
Electronics  Corporation,  National Draeger Inc., Gastech Inc., General Monitors
Inc., Mine Safety Appliance Company, Seiger, Ltd., and Sensidyne Inc.

      Certain Factors That May Affect Future Results

      This  report  contains  forward-looking  statements  within the meaning of
Section 27A of the  Securities  Act of 1933 and  Section  21E of the  Securities
Exchange  Act of  1934.  Actual  results  could  differ  materially  from  those
projected in the forward-looking  statements as a result of the risk factors set
forth below and elsewhere in this report. 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
yet competitive price.

      The industry in which the Company  competes is highly  competitive and the
Company  expects  such  competition  to  continue  in the  future.  Most  of the
Company's competitors are larger than the Company and have substantially greater
financial,  technical,  marketing and manufacturing resources. While the Company
has invested in new products,  there can be no assurance that it can continue to
introduce  new products on a timely  basis or that certain of its products  will
not be rendered non competitive or obsolete by its competitors.

Item 2.       Description of Property.

      The  Company's  principal  executive,  administrative,  manufacturing  and
engineering  operations  are located in a 15,000 square foot leased  facility in
Milpitas, California. This facility is occupied under a lease expiring March 31,
2001. Management considers that the current facility is adequate for the present
level of operations and that additional office and factory space is available in
the  immediate  vicinity.  The Company also leases sales  offices near  Chicago,
Illinois; Philadelphia, Pennsylvania; and Houston, Texas.

Item 3.       Legal Proceedings.

      To  the  knowledge  of  the  Company's  management,  there  are  no  legal
proceedings  pending to which the  Company is a party or to which the  Company's
property is subject.

Item 4.       Submission of Matters to a Vote of Security Holders.

      The  Company  did not submit any  matters  to a vote of  security  holders
during the fourth quarter of the fiscal year ended December 31, 1997.

                                     PART II


Item 5.       Market for Registrant's  Common Equity and Related  Stockholder
              Matters.

      (a)  There  is not an  active  market  for  the  Company's  stock  and the
Company's  stock is  currently  traded  solely  on the  NASDAQ  over-the-counter
Bulletin Board. To the Company's knowledge,  there is only infrequent trading in
limited  volume.  The  Company  understands  that  trades in Common  Stock  from
September  1997 to December 1997 have been effected at prices ranging from $0.19
to $0.20 per share. Because trading of the Company's stock is so infrequent, the
Company is unable to provide historic price information.

        (b) As of March 15, 1998 there were  approximately 359 holders of record
of the Company's Common Stock.

        (c) The Company has never paid cash  dividends on its Common Stock.  The
Company presently intends to retain any future earning to finance operations and
the further  development of the Company's business and does not presently intend
to disperse any cash dividends in the foreseeable future.

Item 6.       Management's Discussion and Analysis of Financial Condition and
              Results of Operations.

Results of Operations

Fiscal 1997 vs. Fiscal 1996

      For the year ended  December 31, 1997,  the Company  reported net sales of
$5,130,597  compared to net sales of $5,040,177 in the prior year. Income before
income taxes was $141,065 in 1997 compared to $139,930 in the previous year. Net
income in 1997 was  $189,204  due to the effect of a net  income tax  benefit of
$48,139.  Net income in 1996 was  $149,430 due to the effect of a net income tax
benefit of $9,500.  The  components  of the income tax benefit are  described in
note 7 to the financial statements  incorporated in this report as Part IV, Item
13 (a).

      Sales  increased  by 1.8% over the prior year.  There were no  significant
changes in selling prices.  The increase in net sales is primarily the result of
the  improved  volume  of  sales of gas  detection  products  used by  telephone
companies including the company's new Environment Controller. Lower sales of the
Company's  primary gas  detection  product,  Sentry,  were  partially  offset by
improved sales of other  industrial  gas detection  products and higher sales to
the United States Navy.

      Gross  profit as a percent  of sales  was 63.0%  compared  to 61.6% in the
prior year.  Manufacturing  labor  costs and  materials  costs,  as a percent of
sales, remained constant compared with the previous year's commercial sales.

      Research and development  expenses,  which include sustaining  engineering
for existing  products,  were $423,058,  or 8.2% of net sales, in the year ended
December  31, 1997  compared to  $439,017,  or 8.7% of sales,  in the year ended
December 31, 1996.  Research and development  expenses in 1997 and 1996, include
costs  of  approximately   $21,578  and  $75,300,   respectively,   for  outside
consultants and other purchased services used in the development of new products
including the  Environment  Controller  which was released for sale in telephone
company applications late in the second half of 1996.


                                       4
<PAGE>

      Selling and marketing expenses increased in 1997 to $1,705,671 or 33.2% of
net sales, from $1,662,602, or 33.0% of net sales, in the prior year. There were
no  significant  changes in selling and  marketing  expenses in 1997 compared to
1996 except that  commissions paid to independent  representatives  were 7.6% of
sales   compared  to  8.5%  in  the  prior  year.   Commissions  to  independent
representatives  vary as a percent of sales due to product  mix and  channels of
distibution used to sell products.

      General and  administrative  expenses  increased  to $992,529 in 1997 from
$891,197 in 1996. The higher general and administrative  expenses are the result
of higher labor expenses,  due to employee additions and temporary workers,  and
higher professional services expenses.

      Net interest income in 1997 was $28,050  compared with net interest income
of  $28,417  in  1996.  Due to the  fact  that  the  Company  did not  have  any
outstanding  long-term  debt during 1997, the Company did not incur any interest
expense for the year.

      An income tax benefit of $48,139 in 1997 resulted from changes in deferred
tax assets and liabilities and a change in the valuation allowance,  compared to
a benefit of $9,500 in 1996.

Fiscal 1996 vs. Fiscal 1995

      For the year ended  December 31, 1996,  the Company  reported net sales of
$5,040,177  compared to net sales of $4,773,464 in the prior year. Income before
income taxes was $139,930 in 1996 compared to $30,524 in the previous  year. Net
income  in 1996 was  $149,430  due to the  effect of an income  tax  benefit  of
$9,500.  The  increase in net income was  primarily  due to the higher  level of
sales without substantial increases in fixed costs.

      Sales  increased  by 5.6% over the prior year.  There were no  significant
changes in selling prices. The increase in net sales was primarily the result of
the  improved  volume  of  sales of gas  detection  products  used by  telephone
companies,  although  there  were no  significant  sales  of the  company's  new
Environment  Controller for telephone company  applications.  Sales of other gas
detection products remained approximately the same as the prior year.

      Gross  profit as a percent  of sales  was 61.6%  compared  to 61.2% in the
prior year.  Manufacturing  labor  costs and  materials  costs,  as a percent of
sales, remained constant compared with the previous year's commercial sales.

      Research and development  expenses,  which include sustaining  engineering
for existing  products,  were $439,017,  or 8.7% of net sales, in the year ended
December  31, 1996  compared to  $406,278,  or 8.5% of sales,  in the year ended
December 31, 1995. Research and development expenses in, 1996 and 1995, included
costs  of  approximately   $75,300  and  $48,400,   respectively,   for  outside
consultants  and  other  purchased  services  used in the  development  of a new
product which was released for sale in telephone  company  applications  late in
the second half of 1996.

      Selling and marketing expenses decreased in 1996 to $1,662,602 or 33.0% of
net sales, from $1,668,079, or 34.9% of net sales, in the prior year. There were
no  significant  changes in selling and  marketing  expenses in 1996 compared to
1995 except that  commissions paid to independent  representatives  were 8.5% of
sales   compared  to  9.1%  in  the  prior  year.   Commissions  to  independent
representatives  vary as a percent of sales due to product  mix and  channels of
distibution used to sell products.


                                       5
<PAGE>

      General and  administrative  expenses  increased  to $891,197 in 1996 from
$844,929 in 1995.  The increase was  primarily  due to higher  salary,  wage and
benefit expenses which were incurred to support  increased  material control and
accounting activities.

      Net interest income in 1996 was $28,417  compared with net interest income
of  $30,479  in  1995.  Due to the  fact  that  the  Company  did not  have  any
outstanding  long-term  debt during 1996, the Company did not incur any interest
expense for the year.

      An income tax benefit of $9,500 in 1996  resulted from changes in deferred
tax assets and liabilities and a change in the valuation allowance,  compared to
a tax expense of $12,500 in 1995.

Liquidity and Capital Resources

      The Company's  working  capital  increased an additional  $190,641 in 1997
over the  increase of  $164,895  in 1996.  Working  capital  was  $2,369,675  at
December 31, 1997 compared to $2,179,034 at December 31, 1996.

      Inventory  levels  increased  11.1%  during  1997.  Inventory  on hand was
$797,546 at December 31, 1997. Inventories were increased during the second half
of 1997 to insure the Company's  ability to provide  quick  delivery of customer
orders. The Company believes that its ability to deliver product with short lead
times provides a competitive advantage.

      The  Company  had no  long  term  liabilities  and no bank  borrowings  at
December 31, 1997.

      The  Company  maintains  a $250,000  line of credit,  secured by  accounts
receivable,  with its commercial bank. There were no borrowings against the line
of credit in 1997. The Company is in full  compliance with the terms of the line
of credit and  currently  anticipates  that it will be renewed on similar  terms
upon its expiration in June 1998.

      At December 31, 1997 the balance sheet reflected $297,485 of cash and cash
equivalents,  $441,833 of short term  investments  and  $833,344 of net accounts
receivable.  Total cash, cash equivalents and short term investments of $739,318
at the end of 1997  were  approximately  the same as the end of 1996.  The short
term  investments  consist of certain  Federal Agency  Securities  with original
maturities greater than 90 days. Management believes that its present resources,
including cash, cash equivalents,  bank line of credit and accounts  receivable,
are sufficient to fund its anticipated level of operations  through December 31,
1998.

Year 2000 Planning

Management  has  initiated an  enterprise-wide  program to prepare the Company's
computer based systems and microprocessor  based products for the year 2000. The
Company  expects to incur  internal  staff costs as well as consulting and other
expenses related to testing and procedure  enhancements necessary to prepare the
systems for the year 2000. The total cost of the preparation and  implementation
is estimated to be less tan $100,000 and is being funded through  operating cash
flows. A significant  proportion of these costs are not likely to be incremental
costs to the Company,  but rather will  represent the  redeployment  of existing
technical and personnel resources.

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.

Item 7.       Financial Statements and Supplementary Data.

      Reference is made to the financial  statements and supplementary  data set
forth in this Form 10-KSB report, as indexed in Item 13, in Part IV, and by such
reference such information is incorporated herein.

Item 9.       Recent Account Pronouncements.

      On July 1, 1996,  the FASB issued SFAS No.  130,  Reporting  Comprehensive
Income.  This  statement  establishes  standards  for  reporting  and display of
comprehensive income and its components  (including revenues,  expenses,  gains,
and  losses)  in a full  set  of  general  purpose  financial  statements.  This
statement is effective for fiscal years beginning after December 15, 1997.

      The FASB also recently issued SFAS No. 131,  Disclosures about Segments of
an Enterprise and Related  Information.  SFAS No. 131 requires certain financial
and supplementary information to be disclosed on an annual and interim basis for
each reportable  segment of an enterprise.  SFAS No. 131 is effective for fiscal
years  beginning  after December 31, 1997.  The  statement's  interim  reporting
disclosures would not be required until the first quarter immediately subsequent
to the fiscal year in which SFAS No. 131 is effective.  The Company is currently
evaluating the impact of these statements on its financial statements.

                          INDEPENDENT AUDITORS' REPORT









The Board of Directors and Shareholders
Sierra Monitor Corporation:


We have audited the accompanying balance sheets of Sierra Monitor Corporation as
of  December  31,  1997 and 1996,  and the  related  statements  of  operations,
shareholders'  equity,  and cash  flows for each of the years in the  three-year
period  ended   December  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 audit 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 Sierra Monitor  Corporation as
of December 31, 1997 and 1996,  and the results of its  operations  and its cash
flows for each of the years in the three-year period ended December 31, 1997, in
conformity with generally accepted accounting principles.

                          Notes to Financial Statements

                        December 31, 1997, 1996, and 1995




 (1)   Summary of the Company and Significant Accounting Policies

       The Company

       Sierra Monitor  Corporation  (the Company) was  incorporated in September
       1989 to effect the merger of UMF Systems,  Inc. (UMF) and Sierra Holdings
       Corporation  (SHC),  which was originally  incorporated as Sierra Monitor
       Corporation  in 1978.  The  Company's  principal  line of business is the
       design, manufacture, and marketing of instruments that detect and monitor
       hazardous  gases.  The Company  conducts its business within one industry
       segment.

       Use of Estimates

       The Company's  management has made a number of estimates and  assumptions
       relating to the reporting of assets and liabilities and the disclosure of
       contingent  assets and liabilities to prepare these financial  statements
       in conformity  with  generally  accepted  accounting  principles.  Actual
       results could differ from those estimates.

       Revenue Recognition

       Generally,  sales are recorded  when products are shipped or services are
       rendered. Revenues from government contracts are recognized utilizing the
       percentage-of-completion  method.  Contract  revenues are recorded as the
       related costs (including certain general and administrative costs), which
       contribute to contract performance, are incurred.

       Cash and Cash Equivalents

       Cash and cash  equivalents  consist  of cash on  deposit  with  banks and
       highly liquid money market  instruments  with  original  maturities of 90
       days or less. Certain  certificates of deposits with original  maturities
       greater than 90 days are classified as short-term investments.

       Inventories

       Inventories  are  stated at the lower of cost  (first  in,  first out) or
       market.

       Property and Equipment

       Property and equipment are stated at cost less  accumulated  depreciation
       and amortization.  Depreciation is provided on the  straight-line  method
       over the estimated useful lives of the respective  assets,  generally two
       to  three  years.   Leasehold   improvements   are  amortized  using  the
       straight-line  method  over the  shorter  of the lease term or the useful
       life of the related asset.

                    Notes to Financial Statements, Continued


       The Company reviews property and equipment for impairment whenever events
       or changes in circumstances indicate that the carrying amount of an asset
       may not be  recoverable.  Recoverability  of property  and  equipment  is
       measured by comparison of its carrying amount,  including the unamortized
       portion of any goodwill allocated to the property and equipment to future
       undiscounted operating cash flows the property and equipment are expected
       to generate. If such assets are considered to be impaired, the impairment
       to be recognized  is measured by the amount by which the carrying  amount
       of the property and equipment exceeds its fair market value. To date, the
       Company has made no adjustments to the carrying  values of its long-lived
       assets.

       Stock Option Plan

       Prior to January 1, 1996, the Company accounted for its stock option plan
       in accordance  with the provisions of Accounting  Principles  Board (APB)
       Opinion No. 25,  Accounting  for Stock Issued to  Employees,  and related
       interpretations.  As such,  compensation expense would be recorded on the
       date of grant only if the current  market price of the  underlying  stock
       exceeded the exercise price.

       On January 1, 1996, the Company adopted Statement of Financial Accounting
       Standards (SFAS) No. 123, Accounting for Stock-Based Compensation,  which
       permits entities to recognize as expense over the vesting period the fair
       value of all stock-based awards on the date of grant. Alternatively, SFAS
       No. 123 also allows  entities to continue to apply the  provisions of APB
       Opinion  No. 25 and provide pro forma net income and pro forma net income
       per share  disclosures  for employee stock option grants made in 1995 and
       future years as if the fair  value-based  method  defined in SFAS No. 123
       had been  applied.  The  Company  has  elected to  continue  to apply the
       provisions  of APB Opinion  No. 25 and  provide the pro forma  disclosure
       provisions of SFAS No. 123.

       Income Taxes

       Income  taxes are  accounted  for under the asset and  liability  method.
       Deferred tax assets and  liabilities  are  recognized  for the future tax
       consequences  attributable to differences between the financial statement
       carrying  amounts of existing assets and liabilities and their respective
       tax bases and operating loss and tax credit  carryforwards.  Deferred tax
       assets and  liabilities  are measured using enacted tax rates expected to
       apply to taxable income in the years in which those temporary differences
       are  expected  to be  recovered  or settled.  The effect on deferred  tax
       assets and  liabilities  of a change in tax rates is recognized in income
       in the period that includes the enactment date.

       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.  The following is a
       reconciliation of the shares used in the computation of basic and diluted
       EPS for the years ended December 31, 1997, 1996, and 1995, respectively:

            Diluted EPS -- weighted-average of common
                shares and common equivalent shares                               
                outstanding                                        10,728,834           10,731,161              10,498,260

</TABLE>

       For purposes of calculating diluted EPS, there were no adjustments to net
       income.

        Options to purchase  120,000  shares of common stock at an average price
        of $0.38 per share were granted during the year but were not included in
        the  computation of diluted EPS because the options'  exercise price was
        greater  than the  average  market  price of the  shares.  Such  options
        remained outstanding as of December 31, 1997.


 (2)   Inventories

 (4)   Common Stock

       During 1996,  the  Company's  1986  Incentive  Stock Option Plan expired.
       Subsequently,  the shareholders  adopted the 1996 Stock Plan and reserved
       600,000 shares of common stock for issuance. Under this plan, options may
       be granted at the fair market value of the Company's  common stock at the
       grant date, vest ratably over 4 years, and expire 10 years from the grant
       date.

       Stock options granted were 120,000,  -0-, and 215,000 during 1997,  1996,
       and 1995,  respectively.  The per share  weighted-average  fair  value of
       stock  options  granted  during  1997  and  1995  was  $0.20  and  $0.13,
       respectively, on the date of grant using the Black-Scholes option pricing
       model with the following weighted-average  assumptions for 1997 and 1995:
       expected dividend yield of 0.0% for each year; volatility of 50% for each
       year;  risk-free interest rate of 5.83% and 6.63%,  respectively;  and an
       expected life of 10 years.
<TABLE>

       The Company  applies APB Opinion No. 25 in accounting for its plan,  and,
       accordingly,  no  compensation  cost has been  recognized  for its  stock
       options  in  the  financial   statements.   Had  the  Company  determined
       compensation cost based on the fair value at the grant date for its stock
       options  under SFAS No. 123,  the  Company's  net income  would have been
       reduced to the pro forma amounts indicated below:

            Net income per share:
                As reported (basic and diluted)                                                0.02                   0.01
                Pro forma (basic and diluted)                                                  0.02                   0.01
</TABLE>


       Pro forma net  income  reflects  only  options  granted in 1997 and 1995.
       Therefore,  the full impact of  calculating  compensation  cost for stock
       options  under SFAS No. 123 is not  reflected in the pro forma net income
       amounts  presented above because  compensation cost is reflected over the
       options' vesting period of four years and  compensation  cost for options
       granted prior to January 1, 1995, is not  considered.

</TABLE>

       In assessing the reliability of deferred tax assets, management considers
       whether  it is more  likely  than not  that  some  portion  or all of the
       deferred tax assets will not be realized.  The  ultimate  realization  of
       deferred tax assets is dependent  upon the  generation of future  taxable
       income  during the periods in which those  temporary  differences  become
       deductible.  Management considers the projected future taxable income and
       tax planning  strategies in making this assessment.  Based upon the level
       of historical  taxable income and  projections  for future taxable income
       over the periods which the deferred tax assets are deductible, management
       believes it is more likely than not the Company will realize the benefits
       of these deductible differences.

       The  Company  has  federal  tax  credit  carryforwards  of  approximately
       $106,000,  which can be used to offset against  future income taxes.  The
       credit carryforwards will expire in 1998 through 2010.


(8)    Fair Value of Financial Instruments

       The  Financial   Accounting   Standards  Board's  (FASB)  SFAS  No.  107,
       Disclosures about Fair Value of Financial  Instruments,  defines the fair
       value of a  financial  instrument  as the amount at which the  instrument
       could be exchanged in a current transaction between willing parties.  All
       financial  instruments included in the accompanying  financial statements
       approximate   fair  value   because  of  the  short   maturity  of  those
       instruments.

  (9)  Recent Accounting Pronouncements

       On July 1, 1996,  the FASB issued SFAS No. 130,  Reporting  Comprehensive
       Income. This statement establishes standards for reporting and display of
       comprehensive income and its components  (including  revenues,  expenses,
       gains, and losses) in a full set of general purpose financial statements.
       This statement is effective for fiscal years beginning after December 15,
       1997.

       The FASB also recently issued SFAS No. 131, Disclosures about Segments of
       an  Enterprise  and Related  Information.  SFAS No. 131 requires  certain
       financial and supplementary  information to be disclosed on an annual and
       interim basis for each reportable segment of an enterprise.  SFAS No. 131
       is effective  for fiscal years  beginning  after  December 31, 1997.  The
       statement's interim reporting disclosures would not be required until the
       first quarter immediately subsequent to the fiscal year in which SFAS No.
       131 is effective. The Company is currently evaluating the impact of these
       statements on its financial statements.
