              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 - Basis of Presentation:

The  condensed  consolidated  financial  statements  for the three and six month
periods ended June 30, 1997, and 1996 presented in this Quarterly Report on Form
10-Q are  unaudited.  The balance  sheet at December 31, 1996,  has been derived
from the audited  financial  statements at that date but does not include all of
the  information  and  footnotes  required  by  generally  accepted   accounting
principles  for complete  financial  statements.  In the opinion of  management,
these  statements  include all adjustments  (consisting only of normal recurring
adjustments)  necessary  for a fair  statement  of the  results  for the interim
periods presented.  The condensed  consolidated  financial  statements should be
read in conjunction with the audited consolidated financial statements and notes
thereto  included in the Company's  Annual Report to  Shareholders  for the year
ended December 31, 1996.

The results of  operations  for the three month and six month periods ended June
30, 1997 are not necessarily  indicative of the results that may be expected for
the year ending December 31, 1997.

NOTE 3 - New Accounting Standards:

Effective January 1, 1997, the Company adopted Statement of Financial Accounting
Standards  No. 125 ("SFAS  125"),  "Accounting  for  Transfers  and Servicing of
Financial  Assets and  Extinguishments  of  Liabilities."  At June 30, 1997, the
Company was  contingently  liable to a Japanese  bank for  $356,000 at month end
exchange rates arising from customers'  notes  receivable which the Company sold
with recourse to the bank. In accordance with SFAS 125, the Company has recorded
this amount as a liability.


                                       6
<PAGE>

* In February 1997, the Financial  Accounting  Standards Board issued  Statement
No. 128,  "Earnings Per Share",  which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method  currently
used to compute  earnings per share and to restate all prior periods.  Under the
new requirements for calculating primary earnings per share, the dilutive effect
of  stock  options  will  be  excluded.  The  impact  of  Statement  128  on the
calculation  of primary and fully  diluted  earnings  per share for the quarters
reported is not expected to be material.


NOTE 4 - Contingencies:

Shareholder Litigation

On December 6, 1995, two  shareholders  filed a class action lawsuit against the
Company and certain  directors  and officers of the Company.  Subsequent to that
date,  additional lawsuits were filed by other  shareholders.  The lawsuits were
subsequently  amended and  consolidated  into one  complaint  which was filed on
April 5, 1996. The amended consolidated complaint sought to bring an action as a
class action  consisting  of all persons who  purchased  the common stock of the
Company during the period April 18, 1995,  through  December 5, 1995 (the "Class
Period").  The  plaintiffs  alleged  that the  defendants  sought to induce  the
members of the Class to purchase  the  Company's  common  stock during the Class
Period at  artificially  inflated  prices.  The  plaintiffs  seek  recissory  or
compensatory  damages with interest  thereon,  as well as reasonable  attorneys'
fees and extraordinary  equitable and/or injunctive  relief. The Company filed a
motion to dismiss,  which was heard by the Court on August 16,  1996.  The court
rejected  the  plaintiffs'  lawsuit,  but allowed  thirty  days to resubmit  its
complaint.  On September 24, 1996, the plaintiffs filed an amended complaint. On
April 28, 1997,  the Court  granted in part,  and denied in part,  the Company's
motion to dismiss.  The Court further  granted the  plaintiffs  leave to replead
certain  dismissed claims. On June 19, 1997 the plaintiffs filed a third amended
and  consolidated  complaint.  The Company  has filed a motion to  dismiss.  The
Company  does not  believe  that it is  possible  to predict the outcome of this
litigation.

Other Litigation

* In October 1995, an employee who was terminated by the Company in 1992 filed a
Complaint  against  the  Company,  alleging  that his  incentive  stock  options
continued  to  vest  subsequent  to  his   termination.   He  seeks  damages  of
approximately  $1,000,000.  The Company has filed a general  denial in answer to
the Complaint, and a trial date has been set for September 15, 1997. The Company
does not believe that the Complaint will be successful.

In September 1996, the British Technology Group ("BTG") brought suit for alleged
infringement  of its  RE.34,004  patent.  BTG has also  brought suit against two
other  defendants  over the same patent.  Discovery  is underway,  and a Markman
hearing is scheduled in the Eastern  District of  Pennsylvania  for September 9,
1997. Trial is set for January 8, 1998. The Company believes the suit is without
merit and intends to defend itself vigorously.

Note 5 - Line of Credit

In August 1995, the Company entered into a $30,000,000  unsecured line of credit
agreement  with two banks which  expired in July 1997.  In July 1997 the Company
has received an amendment to extend the line of credit to September 1, 1997. The
agreement enables the Company to borrow up to $30,000,000  provided that certain
financial and other  covenants are met. The agreement  provides for payment of a
commitment fee of 0.5% for the unused portion of the line of credit.  Borrowings
bear  interest at the higher of (i) one of the bank's annual prime rate and (ii)
the federal funds rate plus 0.5%.  To date,  no borrowings  have been made under
the line of credit.  Under the current line of credit the Company is  restricted
from paying  dividends.  The Company intends to obtain another line of credit on
similar terms on September 1, 1997.


Note 6 - Subsequent Events:

On July 25,  1997,  the Company  made a bridge loan for $1.5  million to Proshot
Golf, Inc, a minority  investee of the Company,  at prime plus 1.5%. The loan is
due on or before  February  25, 1998 and is secured  entirely by an  irrevocable
stand-by  letter  of  credit  with a  commercial  bank  having  the  Company  as
beneficiary and Proshot as account party.

</TABLE>

Commercial Systems

Commercial Systems revenues for the three month and six month periods ended June
30, 1997  increased  in total over the prior year period,  however,  the Company
experienced  a decrease in the Land Survey  vertical  market as compared to June
30, 1997. However,  the Company believes that it has maintained its market share
worldwide.

The  decreases in Land Survey sales in the second  quarter of 1997,  compared to
the second  quarter of 1996,  are due in part to the continued  slow down of the
European and Japanese economies.

The  decrease  in Land  Survey  sales were  offset by an increase in the overall
Commercial  Systems' revenues for the second quarter of 1997, as compared to the
second  quarter of 1996,  which occurred  primarily in the Precise  Positioning,
GIS, and Tracking vertical markets.

Tracking and  Communications  revenues have  increased in the second  quarter of
1997 compared to the second  quarter of 1996 due to the  resumption of shipments
in March 1997 to American Mobile Satellite  Corporation  (AMSC), a company based
in Reston,  Virginia,  that  provides a variety of voice and data  services  via
satellite. The shipments were originally discontinued late in the fourth quarter
of 1995 at the request of AMSC,  in part due to delays in AMSC's  completion  of
software. On February 20, 1997, an agreement was signed between Trimble and AMSC
to resume shipments of Trimble's  Galaxy/GPS  terminals at the rate of 500 units
per month,  beginning  in March 1997.  


                                       9
<PAGE>


Approximately  1,750 and 2,000  units were  shipped  in the three  month and six
month periods ending June 30, 1997, respectively.

Software and Component Technologies

Software and Component  Technologies  revenues increased for the three month and
six month  periods  ended June 30,  1997,  as  compared  with the  corresponding
periods for 1996 due primarily to a $2.2 million technology license from Pioneer
Electronic  Corporation  in  connection  with the expansion of the original 1992
license for in-car navigation technology recorded in the 1997 periods.

Aerospace

* Sales of  Aerospace  products  increased  for the three and six month  periods
ending June 30, 1997,  compared to the same periods in 1996 primarily due to the
increased  sales of the HT 9100,  Honeywell  Trimble  product line.  The Company
considers  its  Aerospace  products  to be a long term  growth  opportunity.  It
believes  that  success in this area will be  dependent  upon the success of the
current strategic alliance with Honeywell.

* Military sales increased  slightly in the second quarter of 1997,  compared to
the second  quarter of 1996.  Military  sales are highly  dependent on contracts
that are subject to government approval and are, therefore, expected to continue
to fluctuate from period to period.  The Company believes that  opportunities in
this market  have been  substantially  reduced by  cutbacks in U.S.  and foreign
military spending.

Revenue outside the US

* Sales to  unaffiliated  customers  in  locations  outside  the U.S.  comprised
approximately  45% and 48% of  revenue in the first six months of 1997 and 1996,
respectively. During the first six months of 1997, the Company experienced lower
revenues in Europe in many  product  lines,  and in Japan  primarily  related to
surveying  products.  The Company anticipates that export revenue and sales made
by its subsidiaries in locations outside the U.S. will continue to account for a
significant portion of its revenue and, therefore, the Company is subject to the
risks  inherent  in these  sales,  including  unexpected  changes in  regulatory
requirements,  exchange rates, governmental approval, tariffs or other barriers.
Even  though the U.S.  Government  announced  on March 29,  1996,  that it would
support and maintain the GPS system,  as well as eliminate  the use of Selective
Availability  (S/A) (a method of degrading GPS  accuracy),  customers in certain
foreign  markets may be reluctant to purchase  products  based on GPS technology
given the  control  of GPS by the U.S.  Government.  The  Company's  results  of
operations could be adversely affected if the Company were unable to continue to
generate significant sales in locations outside the U.S.


Gross Margin

* Gross margin varies on a quarterly basis due to a number of factors, including
product mix,  technology  license fees,  domestic  versus  international  sales,
customer type, the effects of production volumes and fixed  manufacturing  costs
on unit  product  costs  and new  product  start-up  costs.  Gross  margin  as a


                                       10
<PAGE>

percentage  of total  product  revenue  was 53% for both the three month and six
month periods  ended June 30, 1997,  as compared  with 54% in the  corresponding
1996  periods.  The 1997  margins have been  enhanced by the positive  impact of
non-product  revenues  recognized  from  Pioneer  of $2.2  million in the second
quarter of 1997. Although,  the Company has recorded similar non-recurring items
in the past,  including $2,080,000 in the first six months of 1996, there can be
no assurance that similar items will recur in the future. The lower gross margin
percentage for the 1997 three month and six month periods,  primarily  reflect a
shift in product mix from higher margin Commercial Systems sales to lower margin
Avionics  and OEM  sales  and  decreases  in the  margins  obtained  on sales of
Commercial  Systems products.  There can be no assurance that these margins will
be sustained because of mix changes within and among the business units,  market
pressures on unit selling prices,  fluctuations in unit manufacturing  costs and
other factors.  While Commercial Systems products have the highest gross margins
of all the Company's  products,  those margins have decreased  primarily because
the Company has reduced prices on these products in response to competition. The
Company expects  competition to increase in its Commercial  Systems markets and,
therefore, it is likely that further price erosion will occur, with consequently
lower gross margin percentages in the future.

* The Company  also  expects  that a higher  percentage  of its  business in the
future  will be  conducted  through  alliances  with  strategic  partners,  e.g.
Honeywell,  Caterpillar,  and  Case.  As a  result  of  volume  pricing  and the
assumption of certain operating costs in connection with such partners,  margins
are likely to be lower than sales directly to end-users.

                             ----------  ----------            ----------  ----------
</TABLE>


Research and Development

Research  and  development  expenses  increased in the three month and six month
periods ended June 30, 1997, as compared  with the  corresponding  1996 periods.
The higher  research and  development  expense in the 1997 periods are due to an
increase in personnel and the related  expenses  which  accompany an increase in
the number of employees.  The increase in research and development  personnel is
part of the Company's continuing focus on developing future products.

* The Company  expects  that a  significant  portion of its future  revenues and
operating  income  will  continue to be derived  from sales of newly  introduced


                                       11
<PAGE>

products.  Consequently,  the Company's  future  success  depends in part on its
ability to continue to advance product technology and to develop and manufacture
new  competitive  products  with high  gross  profit  margins.  Development  and
manufacturing  schedules for technology  products are difficult to predict,  and
there can be no assurance that the Company will achieve timely initial  customer
shipments of new products.  The timely  availability of these products in volume
and their  acceptance by customers  are  important to the future  success of the
Company.  In  addition,  certain  of  the  Company's  products  are  subject  to
governmental  and similar  certifications  before they can be sold. For example,
FAA certification is required for all aviation  products.  An inability or delay
in obtaining such  certifications  could have an adverse effect on the Company's
operating results.

Sales and Marketing

The  decreased  sales and  marketing  expenses for the three month and six month
periods ended June 30, 1997, as compared with the corresponding  periods in 1996
is due primarily to a reduction in headcount and related expenses resulting from
the  Company's  restructuring  in  September  1996.  In  addition,  the  Company
experienced  decreases in  advertising  and  promotional  items related to lower
costs for the annual report and lower media development costs.

The  Company's  future  growth  will  depend  upon the  timely  development  and
continued  viability of the markets in which the Company currently  competes and
upon the  Company's  ability to continue to identify and exploit new markets for
its products. In addition, the Company has encountered  significant  competition
in selected  markets,  and the Company expects such  competition to intensify as
the market for GPS applications  receives  acceptance.  Several of the Company's
competitors  are  major  corporations  with  substantially   greater  financial,
technical,  marketing and  manufacturing  resources.  Increased  competition  is
likely to result in reduced  market share and in price  reductions  of GPS-based
products, which could adversely affect the Company's revenues and profitability.

General and Administrative

The decrease in general and  administrative  expense for the three month and six
month periods ended June 30, 1997,  as compared with the  corresponding  periods
for 1996,  primarily  reflects  lower  legal  expenses  as a result  of  reduced
litigation.

Income Taxes

The  effective tax rate was 18% for the three months ended June 30, 1997 and 20%
for the six months ended June 30, 1997 as compared with an effective tax rate of
20% for the same periods in 1996.

Inflation

The  effects of  inflation  on the  Company's  financial  results  have not been
significant to date.

Liquidity and Capital Resources

* For the six month period ended June 30, 1997,  cash  provided  from  operating
activities  was  $12,104,000  as  compared  to cash  used of  $6,041,000  in the
corresponding  period in 1996.  Cash  provided by sales of common  stock in 1997


                                       12

represents  proceeds from purchases made pursuant to the Company's  stock option
and employee  stock  purchase  plans and totaled  $2,703,000  for the six months
ended June 30,  1997.  The  Company  has relied  primarily  on cash  provided by
financing activities and net sales of short-term investments to fund operations,
capital  expenditures,  the repurchase  the Company's  common stock (see further
explanation  below),  and other investing  activities.  The Company's ability to
generate  cash from  operations  will depend in a large part on revenues and the
rate of collections of accounts  receivable.  Management believes that its cash,
cash equivalents and short-term  investment  balances,  with its existing credit
line,  will be  sufficient to meet its  anticipated  cash needs for at least one
year. At June 30, 1997, the Company had cash and cash equivalents of $31,443,000
and short-term investments of $57,028,000.

* In August 1995,  the Company  entered  into an agreement  with two banks for a
$30.0 million  unsecured  line of credit that expired in July 1997.  The line of
credit was  amended in July 1997 to extend  the line of credit to  September  1,
1997. The agreement  enables the Company to borrow up to $30.0 million  provided
that certain  financial and other covenants are met. The agreement  provides for
payment  of a  commitment  fee of 0.5%  for the  unused  portion  of the line of
credit.  Borrowings  bear interest at the higher of (i) one of the bank's annual
prime rate,  and (ii) the federal funds rate plus 0.5%. No borrowings  have been
made under this line of credit.  The Company  intends to obtain  another line of
credit on similar terms after this line expires.

In February  1996, the Company  announced  that it had approved a  discretionary
program  whereby up to 600,000  shares of its common stock may be repurchased by
the Company to offset potential  dilutive effects to earnings per share from the
issuance  of stock  options.  The Company  intends to use  existing  cash,  cash
equivalents  and short-term  investments  to finance any such stock  repurchases
under this program.  In 1996, the Company  purchased 250,000 shares at a cost of
$3,545,000. In the first quarter of 1997, the Company purchased 50,000 shares at
a cost of $673,000.  In the second quarter of 1997 the Company  purchased 89,500
shares at a cost of $1,161,000.

The  Company  is  continually   evaluating  potential  external  investments  in
technologies  related  to its  business  and to date has made  relatively  small
investments in GPS related technology companies.  There can be no assurance that
investments made to date and potential future investments will be successful.

Other Risk Factors

In the past,  revenue has tended to  fluctuate  on a quarterly  basis due to the
timing of shipments of products under contracts,  the sale of license rights and
seasonal  patterns  favoring  spring  and  summer  for  the  Commercial  Systems
business.  However,  the seasonal  patterns were not repeated in 1996,  however,
there  can  be  no  assurances  that  prior  seasonal  revenue  trends  will  be
experienced  during  1997.  A  significant  portion of the  Company's  quarterly
revenues are derived from orders received and  immediately  shipped to customers
in the last few weeks and days of a  quarter.  If orders  are not  received,  or
shipments are delayed  beyond the end of a quarter,  operating  results would be
significantly adversely impacted.



                                       13
<PAGE>


* The Company has a relatively  fixed cost  structure in the short term which is
determined by the business plans and strategies the Company intends to implement
in the markets it addresses.  This effective  leveraging means that increases or
decreases  in  revenues  have more than a  proportional  impact on net income or
losses.  The Company  estimates  that a change in product  revenue of $1 million
would cause a corresponding change in the Company's earnings per share by 2 to 3
cents.

* In the longer term,  the Company  believes  that the  Software  and  Component
Technologies  business unit will comprise a significant portion of the Company's
business.  The  Software and  Component  Technologies  business  unit differs in
nature from most of the Company's  markets  because volumes are high and margins
relatively  low.  Software and  Component  Technologies  customers are extremely
price   sensitive.   To  the  extent,   if  any,  that  costs  decrease  through
technological advances, a portion of these cost savings will be passed on to the
customer. To compete in the Software and Component  Technologies market requires
high-volume  production  and  manufacturing  techniques.  Customers  expect high
quality  standards  with  very low  defect  rates.  The  Company  is  relatively
inexperienced  compared  to  competitors  with  far  greater  resources  in such
high-volume  manufacturing  and  associated  support  activities.  The Company's
failure to meet customer  expectations in this market could cause the Company to
lose customer  orders,  which could result in a material  adverse  effect on the
Company's operating results.

The  Company's  stock price is subject to  significant  volatility.  If revenues
and/or earnings fail to meet the expectations of the investment community, there
could  be an  immediate  and  significant  impact  on the  trading  price of the
Company's stock.

The  value of the  Company's  products  relies  substantially  on the  Company's
technical  innovation in fields in which there are many current patent  filings.
The  Company  recognizes  that as new  patents  are issued or are brought to the
Company's  attention by the holders of such patents, it may be necessary for the
Company to withdraw  products  from the market,  take a license from such patent
holders,  or redesign  its  products.  The  Company  does not believe any of its
products  infringe  patents or other  proprietary  rights of third parties,  but
cannot  be  certain  they  do  not do so.  In  addition,  the  legal  costs  and
engineering  time  required  to  safeguard  intellectual  property  or to defend
against litigation could become a significant expense of operations. Such events
could have a material adverse effect on the Company's revenues or profitability.
(See Note 4- Other Litigation:, to the financial statements)

The Company is  continually  evaluating  alliances and external  investments  in
technologies  related to its business and has already entered into alliances and
made  relatively  small  investments  in  GPS  related   technology   companies.
Acquisitions  of companies,  divisions of  companies,  or products and alliances
entail  numerous  risks,  including (i) the potential  inability to successfully
integrate acquired operations and products or to realize anticipated  synergies,
economies of scale or other value, (ii) diversion of management's attention, and
(iii) loss of key employees of acquired operations. Any such problems could have
a material  adverse effect on the Company's  business,  financial  condition and
results of  operations.  No  assurances  can be given that the Company  will not
incur problems from current or future alliances,  acquisitions,  or investments.
Furthermore,  there can be no assurance that the Company will realize value from
any such alliances, acquisitions, or investments.


                                       14

The  Company's  products rely on signals from the GPS Navstar  satellite  system
built and maintained by the U.S.  Department of Defense.  Navstar satellites and
their  ground  support  systems  are  complex   electronic  systems  subject  to
electronic  and  mechanical  failures  and possible  sabotage.  Some of these 24
satellites have exceeded their design lives of 7.5 years and are also subject to
damage by the hostile space environment in which they operate. Repair of damaged
or  malfunctioning   satellites  is  impossible.  If  a  significant  number  of
satellites were to become inoperable,  there could be a substantial delay before
they are replaced  with new  satellites.  A reduction in the number of operating
satellites  would impair the current utility of the GPS system and the growth of
current  and  additional  market  opportunities.  In  addition,  there can be no
assurance that the U.S.  Government  will remain  committed to the operation and
maintenance of GPS  satellites  over a long period of time, nor that policies of
the U.S.  Government  allowing  for the use of GPS  without  charge  will remain
unchanged. Because of ever increasing commercial applications of GPS, other U.S.
Government  agencies may become involved in the administration or the regulation
of the  use of GPS  signals.  Any of the  foregoing  factors  could  affect  the
willingness  of buyers of the  Company's  products to select  GPS-based  systems
instead of products  based on competing  technologies.  Any resulting  change in
market  demand for GPS  products  would have a  material  adverse  effect on the
Company's  financial  results.  Certain European  government  organizations have
expressed concern  regarding the  susceptibility of GPS equipment to intentional
or inadvertent  signal  interference.  Such concern could translate into reduced
demand for GPS products in certain geographic regions.

                                CORPORATE OFFICES

       I.1    PRINCIPAL OFFICE

        The board of directors shall fix the location of the principal executive
office  of the  corporation  at  any  place  within  or  outside  the  State  of
California. If the principal executive office is located outside such state, and
the  corporation  has one or more business  offices in such state,  the board of
directors  shall fix and designate a principal  business  office in the State of
California.

        I.2    OTHER OFFICES.

        The board of directors may at any time  establish  branch or subordinate
offices  at any  place or  places  where  the  corporation  is  qualified  to do
business.

        II.1   PLACE OF MEETINGS.

        Meetings of  shareholders  shall be held at any place  within or outside
the State of California designated by the board of directors.  In the absence of
any such  designation,  shareholders'  meetings  shall be held at the  principal
executive office of the corporation.

        II.2   ANNUAL MEETING.

        The annual meeting of shareholders shall be held each year on a date and
at a  time  designated  by the  board  of  directors.  In the  absence  of  such
designation,  the  annual  meeting of  shareholders  shall be held on the fourth
Thursday  of April in each  year at 4:00  p.m.  However,  if such day falls on a
legal holiday,  then the meeting shall be held at the same time and place on the
next succeeding  full business day. At the meeting,  directors shall be elected,
and any other proper business may be transacted.

        II.3   SPECIAL MEETING

        A special meeting of the  shareholders  may be called at any time by the
board of directors,  or by the chairman of the board, or by the president, or by
one or more  shareholders  holding shares in the aggregate  entitled to cast not
less than ten percent (10%) of the votes at that meeting.

        If a special  meeting is called by any person or persons  other than the
board of directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business  proposed to be  transacted,  and
shall be delivered  personally or sent by registered  mail or by  telegraphic or
other facsimile  transmission to the chairman of the board,  the president,  any
vice president or the secretary of the  corporation.  The officer  receiving the
request shall cause notice to be promptly given to the shareholders  entitled to
vote,  in  accordance  with  the  provisions  of  Sections  2.4 and 2.5 of these
by-laws,  that a meeting  will be held at the time  requested  by the  person or
persons calling the meeting,  not less than thirty-five (35) nor more than sixty
(60) days after the receipt of the  request.  If the notice is not given  within
twenty (20) days after receipt of the request,  the person or persons requesting
the meeting may give the notice.  Nothing  contained  in this  paragraph of this
Section 2.3 shall be construed as limiting,  fixing or affecting the time when a
meeting of shareholders called by action of the board of directors may be held.

        II.4   NOTICE OF SHAREHOLDERS' MEETINGS.

        All notices of meetings of shareholders shall be sent or otherwise given
in accordance  with Section 2.5 of these by-laws not less than ten (10) nor more
than sixty (60) days before the date of the meeting.  The notice  shall  specify
the  place,  date  and  hour of the  meeting  and (i) in the  case of a  special
meeting,  the general nature of the business to be transacted (no business other
than that  specified in the notice may be transacted) or (ii) in the case of the
annual  meeting,  those  matters  which the board of  directors,  at the time of
giving the notice, intends to present for action by the shareholders. The notice
of any meeting at which  directors  are to be elected  shall include the name of
any nominee or nominees whom, at the time of the notice,  management  intends to
present for election.

        If action is proposed  to be taken at any meeting for  approval of (i) a
contract or transaction  in which a director has a direct or indirect  financial
interest,  pursuant to Section 310 of the  Corporations  Code of California (the
"Code"), (ii) an amendment of the articles of incorporation, pursuant to Section
902 of the Code, (iii) a reorganization of the corporation,  pursuant to Section
1201 of the Code, (iv) a voluntary  dissolution of the corporation,  pursuant to
Section 1900 of the Code, or (v) a  distribution  in  dissolution  other than in
accordance with the rights of outstanding preferred shares,  pursuant to Section
2007 of the  Code,  the  notice  shall  also  state the  general  nature of that
proposal.

        II.5   MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE.

        Notice of any meeting of shareholders  shall be given either  personally
or by first-class  mail or telegraphic or other written  communication,  charges
prepaid,  addressed  to the  shareholder  at the  address  of  that  shareholder
appearing on the books of the  corporation  or given by the  shareholder  to the
corporation  for the  purpose  of  notice.  If no such  address  appears  on the
corporation's  books or is given,  notice  shall be deemed to have been given if
sent to that  shareholder  by  first-class  mail or telegraphic or other written
communication to the corporation's  principal  executive office, or if published
at least once in a newspaper  of general  circulation  in the county  where that
office is  located.  Notice  shall be deemed to have been given at the time when
delivered personally or deposited in the mail or sent by telegram or other means
of written communication.


                                       23
<PAGE>


        If any  notice  addressed  to a  shareholder  at  the  address  of  that
shareholder  appearing  on the  books  of the  corporation  is  returned  to the
corporation  by the United  States  Postal  Service  marked to indicate that the
United States Postal Service is unable to deliver the notice to the  shareholder
at that address, all future notices or reports shall be deemed to have been duly
given without  further mailing if the same shall be available to the shareholder
on written demand of the  shareholder at the principal  executive  office of the
corporation  for a period  of one (1) year  from the date of the  giving  of the
notice.

        An  affidavit  of the mailing or other means of giving any notice of any
shareholders'  meeting,  executed by the secretary,  assistant  secretary or any
transfer  agent of the  corporation  giving  the  notice,  shall be prima  facie
evidence of the giving of such notice.

        II.6   QUORUM

        The  presence  in person or by proxy of the holders of a majority of the
shares  entitled to vote thereat  constitutes  a quorum for the  transaction  of
business at all meetings of  shareholders.  The  shareholders  present at a duly
called or held  meeting at which a quorum is present may continue to do business
until  adjournment,  notwithstanding  the withdrawal of enough  shareholders  to
leave less than a quorum,  if any  action  taken  (other  than  adjournment)  is
approved by at least a majority of the shares required to constitute a quorum.

        II.7   ADJOURNED MEETING; NOTICE.

        Any shareholders' meeting, annual or special, whether or not a quorum is
present,  may be adjourned  from time to time by the vote of the majority of the
shares  represented  at that meeting,  either in person or by proxy,  but in the
absence of a quorum, no other business may be transacted at that meeting, except
as provided in Section 2.6 of these by-laws.

        When any meeting of shareholders, either annual or special, is adjourned
to another time or place,  notice need not be given of the adjourned  meeting if
the time and place are  announced  at the  meeting at which the  adjournment  is
taken,  unless a new record date for the adjourned  meeting is fixed,  or unless
the  adjournment is for more than forty-five (45) days from the date set for the
original meeting,  in which case notice of the adjourned meeting shall be given.
Notice  of any such  adjourned  meeting  shall be given to each  shareholder  of
record  entitled  to  vote at the  adjourned  meeting  in  accordance  with  the
provisions of Sections 2.4 and 2.5 of these  by-laws.  At any adjourned  meeting
the  corporation  may transact any business which might have been  transacted at
the original meeting.

        II.8   VOTING.

        The shareholders  entitled to vote at any meeting of shareholders  shall
be  determined  in  accordance  with the  provisions  of  Section  2.11 of these
by-laws,  subject to the  provisions of Sections 702 to 704,  inclusive,  of the
Code  (relating  to  voting  shares  held  by a  fiduciary,  in  the  name  of a
corporation or in joint ownership).

        The  shareholders'  vote may be by voice  vote or by  ballot;  provided,
however,  that any election for  directors  must be by ballot if demanded by any
shareholder before the voting has begun.

        On any matter other than the election of directors,  any shareholder may
vote part of the shares in favor of the  proposal  and  refrain  from voting the
remaining  shares or vote them  against the  proposal,  but, if the  shareholder
fails  to  specify  the  number  of  shares  which  the  shareholder  is  voting
affirmatively, it will be conclusively presumed that the shareholder's approving
vote is with respect to all shares which the shareholder is entitled to vote.

                                       24
<PAGE>

        If a quorum is  present,  the  affirmative  vote of the  majority of the
shares  represented  and voting at a  duly-held  meeting  (which  shares  voting
affirmatively  also constitute at least a majority of the required quorum) shall
be the act of the  shareholders,  unless the vote of a greater number, or voting
by classes, is required by the Code or by the articles of incorporation.

        At a  shareholders'  meeting at which  directors  are to be elected,  no
shareholder  shall be entitled to cumulate votes (i.e.  cast for any candidate a
number of votes greater than the number of votes which such shareholder normally
is entitled to cast) unless the candidates' names have been placed in nomination
prior to  commencement of the voting and a shareholder has given notice prior to
commencement of the voting of the shareholder's  intention to cumulate votes. If
any shareholder has given such a notice, then every shareholder entitled to vote
may cumulate votes for candidates  placed in nomination and give one candidate a
number of votes equal to the number of directors to be elected multiplied by the
number of votes to which that shareholder's  shares are entitled,  or distribute
the  shareholder's  votes  on  the  same  principle  among  any  or  all  of the
candidates,  as the shareholder thinks fit. The candidates receiving the highest
number of votes, up to the number of directors to be elected, shall be elected.

        II.9   VALIDATION OF MEETINGS: WAIVER OF NOTICE; CONSENT.

        The  transactions  of any  meeting  of  shareholders,  either  annual or
special,  however called and noticed,  and wherever  held,  shall be as valid as
though had at a meeting duly held after regular call and notice,  if a quorum be
present  either  in  person  or by  proxy,  and if,  either  before or after the
meeting,  each  person  entitled  to vote,  who was not  present in person or by
proxy,  signs a written  waiver of notice  or a consent  to the  holding  of the
meeting or an approval of the minutes  thereof.  The waiver of notice or consent
need not  specify  either the  business to be  transacted  or the purpose of any
annual or special  meeting of  shareholders,  except  that if action is taken or
proposed  to be taken for  approval  of any of those  matters  specified  in the
second  paragraph  of  Section  2.4 of these  by-laws,  the  waiver of notice or
consent  shall  state the  general  nature of the  proposal.  All such  waivers,
consents and approvals shall be filed with the corporate  records or made a part
of the minutes of the meeting.

        Attendance  by a person at a meeting  shall also  constitute a waiver of
notice of that meeting,  except when the person objects, at the beginning of the
meeting,  to the transaction of any business because the meeting is not lawfully
called or convened,  and except that  attendance at a meeting is not a waiver of
any right to object to the  consideration of a matter not included in the notice
of the meeting, if that objection is expressly made at the meeting.

        II.10  SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

        Any  action  which may be taken at any  annual  or  special  meeting  of
shareholders  may be taken  without a meeting and  without  prior  notice,  if a
consent in writing,  setting forth the action so taken, is signed by the holders
of  outstanding  shares  having not less than the  minimum  number of votes that
would be  necessary  to  authorize or take that action at a meeting at which all
shares entitled to vote on that action were present and voted.

        In the case of election of directors,  such a consent shall be effective
only if signed by the holders of all outstanding shares entitled to vote for the
election of directors.

                                       25
<PAGE>

        All such consents  shall be maintained  in the  corporate  records.  Any
shareholder giving a written consent,  or the shareholder's  proxy holders, or a
transferee of the shares, or a personal  representative  of the shareholder,  or
their respective proxy holders,  may revoke the consent by a writing received by
the secretary of the corporation before written consents of the number of shares
required to authorize the proposed action have been filed with the secretary.

        If the  consents  of all  shareholders  entitled  to vote  have not been
solicited  in  writing,  and if  the  unanimous  written  consent  of  all  such
shareholders  shall not have been  received,  the  secretary  shall give  prompt
notice of the corporate action approved by the  shareholders  without a meeting.
Such  notice  shall be given in the manner  specified  in  Section  2.5 of these
by-laws.  In the case of approval of (i) a contract  or  transaction  in which a
director has a direct or indirect financial interest, pursuant to Section 310 of
the Code, (ii)  indemnification of a corporate "agent",  pursuant to Section 317
of the Code, (iii) a reorganization of the corporation, pursuant to Section 1201
of the Code,  and (iv) a distribution  in  dissolution  other than in accordance
with the rights of outstanding preferred shares, pursuant to Section 2007 of the
Code,  the notice shall be given at least ten (10) days before the  consummation
of any action authorized by that approval.

        II.11  RECORD DATE FOR SHAREHOLDER NOTICE, VOTING AND GIVING CONSENTS.

        For purposes of determining the  shareholders  entitled to notice of any
meeting or to vote  thereat or  entitled  to give  consent to  corporate  action
without a meeting,  the board of directors  may fix, in advance,  a record date,
which  shall not be more than sixty (60) days nor less than ten (10) days before
the date of any such  meeting  nor more than  sixty  (60) days  before  any such
action without a meeting,  and in such event only  shareholders of record on the
date so fixed are  entitled  to notice and to vote or to give  consents,  as the
case may be,  notwithstanding  any  transfer  of any  shares on the books of the
corporation after the record date, except as otherwise provided in the Code.

        If the board of directors does not so fix a record date:

               (a) the record  date for  determining  shareholders  entitled  to
notice  of or to vote at a  meeting  of  shareholders  shall be at the  close of
business on the business day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held; and

               (b) the record date for determining shareholders entitled to give
consent  to  corporate  action in writing  without a meeting,  (i) when no prior
action by the board has been taken,  shall be the day on which the first written
consent is given or (ii) when prior action by the board has been taken, shall be
the day on which the board adopts the resolution relating to that action, or the
sixtieth (60th) day before the date of such other action, whichever is later.

        The record  date for any other  purpose  shall be as provided in Article
VIII of these by-laws.

        II.12  PROXIES

        Every person  entitled to vote for  directors,  or on any other  matter,
shall  have  the  right  to do so  either  in  person  or by one or more  agents
authorized  by a written proxy signed by the person and filed with the secretary
of the corporation.  A proxy shall be deemed signed if the shareholder's name is
placed  on the proxy  (whether  by manual  signature,  typewriting,  telegraphic
transmission   or   otherwise)   by  the   shareholder   or  the   shareholder's
attorney-in-fact.  A validly  executed  proxy  which  does not state  that it is


                                       26
<PAGE>

irrevocable  shall  continue in full force and effect  unless (i) revoked by the
person  executing  it,  before the vote  pursuant  to that  proxy,  by a writing
delivered  to the  corporation  stating  that  the  proxy  is  revoked,  or by a
subsequent  proxy executed by the person executing the prior proxy and presented
to the meeting, or as to any meeting by attendance at such meeting and voting in
person by the person  executing the proxy or (ii) written notice of the death or
incapacity of the maker of that proxy is received by the corporation  before the
vote pursuant to that proxy is counted;  provided,  however, that no proxy shall
be valid after the  expiration of eleven (11) months from the date of the proxy,
unless otherwise  provided in the proxy. The revocability of a proxy that states
on its face  that it is  irrevocable  shall be  governed  by the  provisions  of
Sections 705(e) and 705(f) of the Code.

        II.13  INSPECTORS OF ELECTION

        Before any meeting of  shareholders,  the board of directors may appoint
an inspector or inspectors of election to act at the meeting or its adjournment.
If no  inspector of election is so  appointed,  the chairman of the meeting may,
and on the request of any shareholder or a shareholder's proxy shall, appoint an
inspector  or  inspectors  of  election  to act at the  meeting.  The  number of
inspectors  shall be either one (1) or three (3). If inspectors are appointed at
a meeting  pursuant to the request of one (1) or more  shareholders  or proxies,
the  holders of a majority  of shares or their  proxies  present at the  meeting
shall determine whether one (1) or three (3) inspectors are to be appointed.  If
any person  appointed as  inspector  fails to appear or fails or refuses to act,
the chairman of the meeting may,  and upon the request of any  shareholder  or a
shareholder's proxy shall, appoint a person to fill that vacancy.

        Such inspectors shall:

               (a)  Determine  the number of shares  outstanding  and the voting
power of each, the number of shares represented at the meeting, the existence of
a quorum, and the authenticity, validity and effect of proxies;

               (b)    Receive votes, ballots or consents;

               (c)    Hear and  determine  all  challenges  and questions in any
way arising in connection with the right to vote;

               (d)    Count and tabulate all votes or consents;

               (e)    Determine when the polls shall close;

               (f)    Determine the result; and

               (g) Do any other acts that may be proper to conduct the  election
or vote with fairness to all shareholders.

                                   ARTICLE III

                                    DIRECTORS

        III.1  POWERS.

        Subject  to the  provisions  of the  Code  and  any  limitations  in the
articles of  incorporation  and these by-laws  relating to action required to be
approved by the  shareholders  or by the  outstanding  shares,  the business and
affairs of the  corporation  shall be managed and all corporate  powers shall be
exercised by or under the direction of the board of directors.

        III.2  NUMBER AND QUALIFICATION OF DIRECTORS

        The number of directors of the  corporation  shall be not less than four
(4) nor more than seven (7).  The exact  number of  directors  shall be five (5)
until  changed,  within the limits  specified  above,  by a bylaw  amending this
Section 3.2, duly adopted by the board of directors or by the shareholders.  The
indefinite  number of  directors  may be  changed,  or a definite  number  fixed
without  provision for an indefinite  number, by a duly adopted amendment to the
articles of  incorporation  or by an amendment to this bylaw duly adopted by the
vote or written  consent of holders  of a  majority  of the  outstanding  shares
entitled to vote;  provided,  however,  that an amendment reducing the number or
the minimum number of directors to a number less than five (5) cannot be adopted
if the votes cast against its adoption at a meeting of the shareholders,  or the
shares not  consenting  in the case of action by written  consent,  are equal to
more than sixteen and two-thirds  percent  (16-2/3%) of the  outstanding  shares
entitled to vote thereon.  No amendment may change the stated  maximum number of
authorized  directors to a number  greater than two (2) times the stated minimum
number of directors minus one (1).

        III.3  ELECTION AND TERM OF OFFICE OF DIRECTORS

        Directors  shall be elected at each annual  meeting of  shareholders  to
hold  office  until the next such annual  meeting.  Each  director,  including a
director  elected to fill a vacancy,  shall hold office until the  expiration of
the term for which elected and until a successor has been elected and qualified.

        III.4  VACANCIES

        Vacancies in the board of  directors  may be filled by a majority of the
remaining directors, though less than a quorum, or by a sole remaining director,
except  that a vacancy  created  by the  removal  of a  director  by the vote or
written consent of the  shareholders or by court order may be filled only by the
vote  of  a  majority  of  the  outstanding  shares  entitled  to  vote  thereon
represented  at a duly  held  meeting  at which a quorum is  present,  or by the
unanimous written consent of all shares entitled to vote thereon.  Each director
so elected shall hold office until the next annual  meeting of the  shareholders
and until a successor has been elected and qualified.

        A vacancy  or  vacancies  in the board of  directors  shall be deemed to
exist in the event of the death,  resignation or removal of any director,  or if
the board of directors by  resolution  declares  vacant the office of a director
who has been  declared of unsound  mind by an order of court or  convicted  of a
felony,  or if the  authorized  number  of  directors  is  increased,  or if the
shareholders  fail,  at any  meeting of  shareholders  at which any  director or
directors  are  elected,  to elect the number of directors to be elected at that
meeting.

                                       28
<PAGE>

        The  shareholders  may elect a director or directors at any time to fill
any vacancy or  vacancies  not filled by the  directors,  but any such  election
other than to fill a vacancy created by removal,  if by written  consent,  shall
require  the  consent of the  holders of a majority  of the  outstanding  shares
entitled to vote thereon.

        Any  director  may  resign  effective  on giving  written  notice to the
chairman of the board,  the president,  the secretary or the board of directors,
unless  the  notice  specifies  a later  time for  that  resignation  to  become
effective.  If the  resignation of a director is effective at a future time, the
board of  directors  may elect a successor  to take office when the  resignation
becomes effective.

        No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

        III.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE

        Regular  meetings  of the  board of  directors  may be held at any place
within or outside the State of California  that has been designated from time to
time by resolution of the board.  In the absence of such a designation,  regular
meetings  shall be held at the principal  executive  office of the  corporation.
Special  meetings  of the board may be held at any place  within or outside  the
State of California that has been designated in the notice of the meeting or, if
not stated in the notice or if there is no notice,  at the  principal  executive
office of the corporation.

        Any meeting,  regular or special, may be held by conference telephone or
similar communication  equipment,  so long as all directors participating in the
meeting  can hear one  another;  and all such  directors  shall be  deemed to be
present in person at the meeting.

        III.6  REGULAR MEETINGS

        Regular meetings of the board of directors may be held without notice if
the times of such meetings are fixed by the board of directors.

        III.7  SPECIAL MEETINGS

        Special  meetings of the board of directors  for any purpose or purposes
may be called at any time by the chairman of the board, the president,  any vice
president, the secretary or any two directors.

        Notice  of the time and place of  special  meetings  shall be  delivered
personally  or by  telephone  to each  director or sent by  first-class  mail or
telegram, charges prepaid, addressed to each director at that director s address
as it is shown on the records of the  corporation.  If the notice is mailed,  it
shall be deposited  in the United  States mail at least four (4) days before the
time of the holding of the meeting. If the notice is delivered personally, or by
telephone or telegram,  it shall be delivered  personally  or by telephone or to
the  telegraph  company at least  forty-eight  (48) hours before the time of the
holding of the meeting.  Any oral notice given personally or by telephone may be
communicated either to the director or to a person at the office of the director
who the person giving the notice has reason to believe will promptly communicate
it to the director.  The notice need not specify the purpose or the place of the
meeting,  if the meeting is to be held at the principal  executive office of the
corporation.

        III.8  QUORUM

        A majority of the  authorized  number of  directors  shall  constitute a
quorum for the transaction of business, except to adjourn as provided in Section
3.10 of these  by-laws.  Every act or decision done or made by a majority of the
directors  present at a duly held meeting at which a quorum is present  shall be
regarded  as the act of the board of  directors,  subject to the  provisions  of
Section 310 of the Code (as to approval of contracts or  transactions in which a
director has a direct or indirect material financial  interest),  Section 311 of
the Code (as to appointment of committees) and Section 317(e) of the Code (as to
indemnification of directors).

        A  meeting  at which a quorum  is  initially  present  may  continue  to
transact  business  notwithstanding  the withdrawal of directors,  if any action
taken is  approved  by at  least a  majority  of the  required  quorum  for that
meeting.

        III.9  WAIVER OF NOTICE.

        The  transactions  of any  meeting  of the board of  directors,  however
called  and  noticed  or  wherever  held,  shall be as valid as though  had at a
meeting  duly held after  regular call and notice if a quorum is present and if,
either  before or after the meeting,  each of the  directors not present signs a
written waiver of notice, a consent to holding the meeting or an approval of the
minutes thereof. The waiver of notice or consent need not specify the purpose of
the meeting.  All such waivers,  consents and approvals  shall be filed with the
corporate  records  or made a part of the  minutes of the  meeting.  Notice of a
meeting  shall also be deemed  given to any  director  who  attends  the meeting
without  protesting,  before or at its commencement,  the lack of notice to that
director.

        III.10 ADJOURNMENT

        A majority  of the  directors  present,  whether or not  constituting  a
quorum, may adjourn any meeting to another time and place.

        III.11 NOTICE OF ADJOURNMENT

        Notice of the time and place of holding an adjourned meeting need not be
given,  unless the meeting is adjourned for more than twenty-four (24) hours, in
which case  notice of the time and place  shall be given  before the time of the
adjourned meeting,  in the manner specified in Section 3.7 of these by-laws,  to
the directors who were not present at the time of the adjournment.

        III.12 ACTION WITHOUT MEETING

        Any action  required or  permitted to be taken by the board of directors
may be taken without a meeting,  if all members of the board shall  individually
or  collectively  consent  in  writing to that  action.  Such  action by written
consent shall have the same force and effect as a unanimous vote of the board of
directors. Such written consent and any counterparts thereof shall be filed with
the minutes of the proceedings of the board.

        III.13 FEES AND COMPENSATION OF DIRECTORS

        Directors and members of committees  may receive such  compensation,  if
any, for their services,  and such reimbursement of expenses, as may be fixed or
determined by resolution of the board of directors.  This Section 3.13 shall not
be construed to preclude any director from serving the  corporation in any other
capacity as an officer, agent, employee or otherwise, and receiving compensation
for those services.

                                   ARTICLE IV

                                   COMMITTEES

        IV.1   COMMITTEES OF DIRECTORS

        The board of directors  may, by resolution  adopted by a majority of the
authorized  number of  directors,  designate  one (1) or more  committees,  each
consisting of two or more directors,  to serve at the pleasure of the board. The
board may  designate  one (1) or more  directors  as  alternate  members  of any
committee,  who may replace any absent  member at any meeting of the  committee.
The appointment of members or alternate members of a committee requires the vote
of a majority of the  authorized  number of  directors.  Any  committee,  to the
extent provided in the resolution of the board,  shall have all the authority of
the board, except with respect to:

        The  corporation  shall have the power,  to the extent and in the manner
permitted by the Code, to indemnify each of its employees and agents (other than

        Expenses   incurred  in  defending  any  civil  or  criminal  action  or
proceeding for which  indemnification is required pursuant to Section 6.1 or for
which   indemnification   is  permitted   pursuant  to  Section  6.2   following
authorization thereof by the Board of Directors shall be paid by the corporation

<PAGE>

        VI.4   INDEMNITY NOT EXCLUSIVE

        The  indemnification  provided  by this  Article  VI shall not be deemed
exclusive  of any other  rights to which those  seeking  indemnification  may be
entitled  under any bylaw,  agreement,  vote of  shareholders  or  disinterested
directors  or  otherwise,  both as to action in an official  capacity  and as to
action in another  capacity  while holding such office,  to the extent that such
additional  rights  to  indemnification   are  authorized  in  the  Articles  of
Incorporation.

        VI.5   INSURANCE INDEMNIFICATION

        The corporation shall have the power to purchase and maintain  insurance
on behalf of any person who is or was a director,  officer, employee or agent of

liability under the provisions of this Article VI.

        VI.6   CONFLICTS

        No  indemnification  or advance  shall be made under  this  Article  VI,
except  where such  indemnification  or advance is mandated by law or the order,
judgment or decree of any court of competent  jurisdiction,  in any circumstance
where it appears:

               (1)  That  it  would  be  inconsistent  with a  provision  of the
Articles of Incorporation,  these bylaws, a resolution of the shareholders or an
agreement  in  effect at the time of the  accrual  of the  alleged  cause of the
action  asserted in the  proceeding in which the expenses were incurred or other
amounts were paid, which prohibits or otherwise limits indemnification; or

               (2) That it would be  inconsistent  with any condition  expressly
imposed by a court in approving a settlement.

                                   ARTICLE VII

                               RECORDS AND REPORTS

shareholders  who are entitled to vote for the election of directors,  and their
shareholdings,  as of the most  recent  record date for which that list has been
compiled or as of a date specified by the shareholder  after the date of demand.
Such list shall be made available to any such  shareholder by the transfer agent
on or before the later of five (5) days after the demand is received or five (5)
days after the date  specified in the demand as the date as of which the list is
to be compiled.

        The  record of  shareholders  shall  also be open to  inspection  on the
written demand of any  shareholder or holder of a voting trust  certificate,  at

as amended to date.

executive office of the  corporation.  The minutes shall be kept in written form
and the accounting  books and records shall be kept either in written form or in
any other form capable of being converted into written form.

        The minutes and accounting books and records shall be open to inspection
upon  the  written  demand  of any  shareholder  or  holder  of a  voting  trust
certificate,  at any reasonable time during usual business hours,  for a purpose
reasonably  related to the holder's  interests as a shareholder or as the holder
of a voting trust  certificate.  The  inspection  may be made in person or by an

rights of inspection shall extend to the records of each subsidiary  corporation
of the corporation.

        VII.4  INSPECTION BY DIRECTORS.

        Every director  shall have the absolute right at any reasonable  time to

documents.

        VII.5  ANNUAL REPORT TO SHAREHOLDERS; WAIVER.

        The board of  directors  shall cause an annual  report to be sent to the

officer of the corporation  that the statements were prepared without audit from
the books and records of the corporation.

        The foregoing requirement of an annual report shall be waived so long as
the shares of the corporation are held by less than one hundred (100) holders of
record.

        VII.6  FINANCIAL STATEMENTS.

        A copy of any annual financial statement and any income statement of the
corporation for each quarterly  period of each fiscal year, and any accompanying
balance  sheet of the  corporation  as of the end of each such period,  that has
been  prepared  by the  corporation  shall  be kept  on  file  in the  principal
executive  office of the  corporation  for  twelve  (12)  months;  and each such
statement  shall  be  exhibited  at all  reasonable  times  to  any  shareholder
demanding an  examination of any such statement or a copy shall be mailed to any
such shareholder.

        If a shareholder or  shareholders  holding at least five percent (5%) of
the outstanding  shares of any class of stock of the corporation makes a written
request to the  corporation  for an income  statement of the corporation for the
three-month,  six-month or  nine-month  period of the then  current  fiscal year
ended  more than  thirty  (30) days  before the date of the  request,  and for a
balance  sheet  of the  corporation  as of the end of  that  period,  the  chief
financial  officer  shall cause that  statement to be  prepared,  if not already
prepared,  and shall deliver  personally or mail that statement or statements to
the person  making the request  within thirty (30) days after the receipt of the
request.  If the corporation has not sent to the  shareholders its annual report
for the last fiscal year,  such report shall  likewise be delivered or mailed to
the shareholder or shareholders within thirty (30) days after the request.

        The corporation  shall also, on the written request of any  shareholder,
mail to the  shareholder  a copy of the last  annual,  semi-annual  or quarterly
income  statement  which it has  prepared,  and a balance sheet as of the end of
that period.

        The quarterly  income  statements and balance sheets referred to in this
section  shall  be  accompanied  by the  report,  if  any,  of  any  independent
accountants  engaged by the  corporation  or the  certificate  of an  authorized
officer of the corporation  that the financial  statements were prepared without
audit from the books and records of the corporation.

                                 GENERAL MATTERS

        VIII.1 RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING.

        For purposes of determining the shareholders entitled to receive payment
of any dividend or other  distribution or allotment of any rights or entitled to
exercise any rights in respect of any other lawful  action (other than action by
shareholders by written  consent without a meeting),  the board of directors may
fix, in  advance,  a record  date,  which shall not be more than sixty (60) days


                                       37
<PAGE>

before  any such  action,  and in that case only  shareholders  of record at the
close of  business on the date so fixed are  entitled  to receive the  dividend,
distribution or allotment of rights, or to exercise such rights, as the case may
be,  notwithstanding  any transfer of any shares on the books of the corporation
after the record date so fixed, except as otherwise provided in the Code.

        If the board of directors does not so fix a record date, the record date
for  determining  shareholders  for any such  purpose  shall be at the  close of
business on the day on which the board adopts the  applicable  resolution or the
sixtieth (60th) day before the date of that action, whichever is later.

        VIII.2 CHECKS, DRAFTS, EVIDENCES OF INDEBTEDNESS.

        All checks,  drafts,  or other  orders for payment of money,  notes,  or
other  evidences  of  indebtedness,  issued  in the  name of or  payable  to the
corporation,  shall be signed or  endorsed by such person or persons and in such
manner as, from time to time,  shall be determined by resolution of the board of
directors.

        VIII.3 CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED.

        The board of directors,  except as otherwise  provided in these by-laws,
may  authorize  any officer or officers,  or agent or agents,  to enter into any
contract  or  execute  any  instrument  in the  name  of and  on  behalf  of the
corporation,  and  such  authority  may  be  general  or  confined  to  specific
instances;  and,  unless so  authorized or ratified by the board of directors or
within the agency power of an officer, no officer,  agent or employee shall have
any power or authority to bind the  corporation by any contract or engagement or
to pledge its credit or to render it liable for any purpose or for any amount.

        VIII.4 CERTIFICATES FOR SHARES

        A certificate or  certificates  for shares of the  corporation  shall be
issued to each shareholder when any of such shares are fully paid, and the board
of directors may authorize the issuance of certificates or shares as partly paid
provided that these  certificates shall state the amount of the consideration to
be paid for them and the amount paid.  All  certificates  shall be signed in the
name of the  corporation  by the  chairman of the board or vice  chairman of the
board or the president or a vice president and by the chief financial officer or
an assistant  treasurer or the secretary or an assistant  secretary,  certifying
the number of shares and the class or series of shares owned by the shareholder.
Any or all of the signatures on the certificate may be facsimile.

        In case any officer, transfer agent or registrar who has signed or whose
facsimile  signature  has been placed on a  certificate  shall have ceased to be
that officer,  transfer agent or registrar before that certificate is issued, it
may be issued by the corporation  with the same effect as if that person were an
officer, transfer agent or registrar at the date of issue.

        VIII.5 LOST CERTIFICATES.

        Except as provided in this Section 8.5, no new  certificates  for shares
shall be issued to replace a previously issued  certificate unless the latter is
surrendered  to the  corporation  and  canceled  at the same time.  The board of
directors  may,  in case any  share  certificate  or  certificate  for any other
security is lost,  stolen or destroyed,  authorize  the issuance of  replacement
certificates  on such terms and  conditions as the board may require,  including
provision  for  indemnification  of the  corporation  secured by a bond or other
adequate security  sufficient to protect the corporation  against any claim that
may be made against it,  including any expense or  liability,  on account of the
alleged loss,  theft or  destruction  of the  certificate or the issuance of the
replacement certificate.

includes  the plural,  the plural  number  includes the  singular,  and the term
