4.   NOTES PAYABLE

     On May 26, 1995, the Company entered into a $3,500,000 working capital
line-of-credit agreement with a commercial finance corporation that bore
interest at the prime rate (8.25% at March 31, 1996) plus 1.75%.  The line-of-
credit facility was collateralized by substantially all of the assets of the
Company.  The proceeds from the funding of this facility were used to repay the
amounts owed to a bank under a line-of-credit agreement which had expired.  On
May 2, 1996, the Company repaid all amounts then outstanding and all accrued
interest owed under the line-of-credit agreement and the agreement was
terminated.

5.   STOCK OPTIONS AND WARRANTS

     During the nine month period ended December 31, 1996, the Company granted
options to purchase 350,000 shares of common stock to key employees pursuant to
the Company's 1994 Stock Option Plan.  The options are exercisable at the
closing price of the common stock on the date of grant.  250,000 of the options
vest over a period of three years and 100,000 of the options were vested on the
date of grant.

     In September 1996, the Company granted options to purchase 25,000 shares of
common stock to each of the five directors serving as chairmen of committees of
the Board of Directors.  The options are exercisable at the closing price of the
common stock on the date of grant and were fully vested on the date of grant,
but are not exercisable until March 1997.

     In May 1996, in connection with the sale of 75 shares of Series C Preferred
Stock, warrants to purchase 30,000 shares of common stock at an exercise price
of $3.00 per share were granted to Maximum Partners, Ltd.

     The private placements of Series B Preferred Stock and Series C Preferred
Stock caused the antidilution provisions of certain stock purchase warrants to
take effect.  Outstanding warrants to purchase 2,459,000 shares of common stock
at an average exercise price of $2.69 per share were affected by the
antidilution provisions, increasing the number of shares issuable upon the
exercise of such warrants to 2,631,284 and decreasing the average exercise price
to $2.51 per share.  Additionally, the antidilution provisions caused the
Company to issue 19,356 additional shares of common stock relating to exercises
of warrants that occurred between the dates of the private placements and the
determination of the effect of antidilution provisions by the Company.

     In November 1996, the Company granted options to purchase 3,000 shares of
common stock to each of the Company's five non-employee directors as a result of
their re-election to the Board of Directors.  The options are exercisable at the
closing price of the common stock on the date of grant and were fully vested on
the date of grant, but are not exercisable until May 1997

     In December 1996, in connection with the sale of 2,496 shares of Series D
Preferred Stock, warrants to purchase 400,000 shares of common stock at an
exercise price of $3.125 per share were sold to the purchasers of the Series D
Preferred Stock.  Also in December 1996, warrants to purchase 100,000 shares of
common stock at an exercise price of $3.125 per share were granted to Strategic
Growth International, Inc. for services in connection with the private placement
of Series D Preferred Stock.

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


RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO
THE THREE MONTHS ENDED DECEMBER 31, 1995

     The Company's sales revenue decreased $1,457,000, or 35%, from $4,207,000
for the quarter ended December 31, 1995 to $2,750,000 for the quarter ended
December 31, 1996 primarily due to a 39% decrease in unit sales, which was
partially mitigated by a 24% increase in average selling prices.  The Company
believes that the remote control niche of the remote access market, which has
historically provided a significant portion of the Company's revenues, is not
experiencing the growth rates that it has enjoyed in the past, and may possibly
be declining, which has adversely affected unit sales of the Company's products.
In response, the Company has increased and redirected its marketing and sales
efforts to penetrate the server consolidation market and the network emulation
market.  The Company believes that its products are well suited to these markets
and that these markets offer the growth potential that no longer appears to be
present in the remote control market.  The Company's ability to increase
revenues will be dependent upon a number of factors, including but not limited
to the market's acceptance of the Company's future products, the ability of the
Company to penetrate new markets in which it has not previously been a
significant participant and the strength of the Company's competition.

     The cost of goods sold decreased $1,137,000, or 40%, from $2,860,000 to
$1,723,000.  The decrease was due to a 43% reduction in material costs related
to the decrease in unit sales and a $42,000, or 13%, decrease in manufacturing
labor and overhead related to a restructuring of the manufacturing department.
The percentage decrease in materials cost was greater than the percentage
decrease in unit sales due to increased average selling prices and an increase
in "turn-key" manufacturing, both of which allow the Company to realize higher
margins.  The restructuring of the Company's manufacturing department included
an increase in the purchase of the electronic subassemblies required for the
manufacture of a significant portion of its products on a "turn-key" basis from
electronics parts distributors.  The "turn-key" purchase allows the Company to
purchase the completed subassembly, as opposed to purchasing the individual
components required for the manufacture of the subassembly and subcontracting
the assembly of the subassembly.  The "turn-key" manufacturing is intended to
allow the Company to take advantage of the purchasing power of the electronics
parts distributor to decrease materials costs, reduce the personnel of the
manufacturing department and lessen the Company's requirement for component
inventories to ensure against interruptions in production.

     Selling expenses increased $104,000, or 15%, from $706,000 to $810,000.
The increase was primarily the result of a constant marketing program throughout
the quarter, whereas marketing efforts had been curtailed to a significant
extent during the prior year due to liquidity constraints and the departure of
the Company's director of marketing.  Selling expense for the quarter ended
December 31 ,1996 was at approximately the same level as for the quarter ended
September 30, 1996.  The Company anticipates some increases in selling expenses
in future quarters due to planned increases in the outside sales force and a
planned increase of marketing efforts directed toward new target markets.

     General and administrative expense decreased $10,000, or 2%, from $525,000
to $515,000.  The decrease was primarily the result of a decrease in legal fees.
During the quarter ended December 31, 1995, the Company changed its outside
corporate counsel, which resulted in additional attorney fees from the
transition.  The decrease was partially offset by increases in salaries related
to the transfer of the Senior Vice President of Technology from the research and
development department to the general and administrative department and the
addition of a Senior Vice President of Business Development.

     Research and development expense increased $109,000, or 54%, from $201,000
to $310,000.  The increase primarily consisted of $48,000 related to personnel
costs and $48,000 in consulting expenses.  These increases are associated with
the Company's efforts to decrease development time for products and increase
product testing during the development cycle.  The personnel cost increases

                                    Page 9
<PAGE>
 
                                 CHATCOM, INC.

included the addition of a Director of Engineering and two engineers.  The
increases were partially offset by the transfer of a Senior Vice President to
the General and Administrative Department.  The Company expects product
development related expenses in the immediate future to approximate those
experienced in the quarter ended December 31, 1996.  Competitive pressure and an
increased rate of development of personal computer related technology, however,
could cause the Company to increase these expense levels, as it will be required
to ensure that its products include, and are compatible with, the technological
advances.

     Interest income increased $11,000 due to larger cash balances during the
quarter, due to proceeds from private placements of preferred stock in March
1996, May 1996 and December 1996 and the exercise of options and warrants in
June 1996.

     Interest expense decreased $50,000, or 97%, from $51,000 to $1,000.  The
decrease was caused by a retirement of the line-of-credit financing agreement
during the quarter ended June 30, 1996.

RESULTS OF OPERATIONS FOR THE NINE MONTHS ENDED DECEMBER 31, 1996 COMPARED TO
THE NINE MONTHS ENDED DECEMBER 31, 1995

     The Company's sales revenue decreased $4,763,000, or 38%, from $12,407,000
to $7,644,000 primarily due to a 45% decrease in unit sales, which was partially
mitigated by a 12% increase in average selling prices.  The Company believes
that the remote control niche of the remote access market, which has
historically provided a significant portion of the Company's revenues, is not
experiencing the growth rates that it has enjoyed in the past, and may possibly
be declining, which has adversely affected unit sales of the Company's products.
In response, the Company has increased and redirected its marketing and sales
efforts to penetrate the server consolidation market and the network emulation
market.  The Company believes that its products are well suited to these markets
and that these markets offer the growth potential that no longer appears to be
present in the remote control market.  The Company's ability to increase
revenues will be dependent upon a number of factors, including but not limited
to the market's acceptance of the Company's future products, the ability of the
Company to penetrate new markets in which it has not previously been a
significant participant and the strength of the Company's competition.

     The cost of goods sold decreased $3,083,000, or 38%, from $8,140,000 to
$5,057,000.  The decrease was due to a 42% reduction in material costs related
to the decrease in unit sales and a $296,000, or 29%, decrease in manufacturing
labor and overhead related to a restructuring of the manufacturing department.
These decreases were partially offset by a $174,000 increase in additions to
inventory reserves related to product changes in response to progressing
technology and market redirection.  The percentage decrease in materials cost
was greater than the percentage decrease in unit sales due to increased average
selling prices and an increase in "turn-key" manufacturing, both of which allow
the Company to realize higher margins.  The restructuring of the Company's
manufacturing department included an increase in the purchase of the electronic
subassemblies required for the manufacture of a significant portion of its
products on a "turn-key" basis from electronics parts distributors.  The "turn-
key" purchase allows the Company to purchase the completed subassembly, as
opposed to purchasing the individual components required for the manufacture of
the subassembly and subcontracting the assembly of the subassembly.  The "turn-
key" manufacturing is intended to allow the Company to take advantage of the
purchasing power of the electronics parts distributor to decrease materials
costs, reduce the personnel of the manufacturing department and lessen the
Company's requirement for component inventories to ensure against interruptions
in production.

     Selling expenses decreased $275,000, or 10%, from $2,661,000 to $2,386,000.
The decrease was primarily the result of a $227,000 decrease in advertising
costs, which was primarily due to a marketing hiatus that occurred from
approximately February 1996 through June 1996 and was related to liquidity
constraints of the Company and a vacancy in the Director of Marketing position.
Additionally, advertising subsequent to the hiatus has focused upon target
market directed advertising, which has 

                                    Page 10

                                 CHATCOM, INC.

reduced the number of publications in which the Company advertises. The Company
anticipates some increases in selling expenses in future quarters due to planned
increases in the outside sales force and a planned increase in marketing efforts
directed toward new target markets.

     General and administrative expense increased $286,000, or 20%, from
$1,433,000 to $1,719,000.  Approximately $100,000 of the increase related to
additions to the allowance for doubtful accounts relating to the Company's
assessment of the collectibility of a receivable from a certain reseller that is
experiencing some financial difficulties.  Approximately $240,000 of the
increase related to the restructuring of the management of the Company, which
included the transfer of two vice presidents from operational cost centers to
the administrative cost center and the addition of a Senior Vice President of
Business Development position.  The increases were partially mitigated by a
decrease in legal fees of $63,000 and by the elimination of the Executive Vice
President position, which resulted in a savings of approximately $100,000.

     Research and development expense increased $98,000, or 15%, from $665,000
to $763,000.  The increase primarily consisted of $30,000 related to personnel
costs and $67,000 in consulting expenses.  These increases are associated with
the Company's efforts to decrease development time for products and increase
product testing during the development cycle.  The personnel cost increases
included the addition of a Director of Engineering and two engineers.  The
increases were partially offset by the transfer of a Senior Vice President to
the General and Administrative Department.  The Company expects product
development related expenses in the immediate future to approximate those
experienced in the quarter ended December 31, 1996.  Competitive pressure and an
increased rate of development of personal computer related technology, however,
could cause the Company to increase these expense levels, as it will be required
to ensure that its products include, and are compatible with, the technological
advances.

     Interest income increased $39,000 due to larger cash balances during the
nine months, due to proceeds from private placements of preferred stock in March
1996, May 1996 and December 1996 and the exercise of options and warrants in
June 1996.

     Interest expense decreased $111,000, or 90%, from $123,000 to $12,000.  The
decrease was caused by a retirement of the line-of-credit financing agreement
during the quarter ended June 30, 1996.

FINANCIAL CONDITION AND CHANGES IN FINANCIAL CONDITION DURING THE NINE MONTHS
ENDED DECEMBER 31, 1996

     The Company recorded a net loss of $2,316,000 for the nine months ended
December 31, 1996.  Cash increased $1,469,000 during the nine months ended
December 31, 1996 and is the result of the receipt of net proceeds of $2,343,000
from the sale of 2,496 shares of Series D Preferred Stock and stock purchase
warrants, net proceeds of $1,325,000 from the sale of 75 shares of Series C
Preferred Preferred Stock and $850,000 in proceeds from the exercise of options
and warrants.  The impact of the proceeds from financing activities on cash flow
was mostly offset by a loss from operations of $2,316,000, and the repayment of
short term borrowings of $938,000.  Working capital increased approximately
$2,150,000, or 61%, from $3,500,000 to $5,650,000 primarily due to the proceeds
from the sale of preferred stock and the exercise of stock options and warrants.

     Accounts receivable decreased $151,000, or 8%, from $1,968,000 to
$1,817,000.  The decrease was primarily attributable to revenues during the two
months (which approximates one receivables cycle) prior to December 31, 1996
being approximately 4% lower than those for the two months prior to March 31,
1996 and the addition of accounts receivable reserves.

     Inventories decreased $462,000, or 13%, from $3,481,000 to $3,019,000.  The
decrease was primarily the result of a decrease in unit sales and "turn-key"
purchasing of subassemblies, which has been implemented by the Company on
certain of its products.  The Company has traditionally purchased the individual
components required to manufacture an electronic assembly, sent the components
to a

subcontractor to be soldered onto the circuit board, and performed final
assembly and test upon its return from the subcontractor. The Company has begun
to institute "turn-key" purchasing for some of its products, whereby the
subassembly is purchased already soldered and ready for final assembly and
testing. The Company intends to implement "turn-key" purchasing for all
assemblies that meet volume thresholds required by the vendor in order to
significantly reduce the requirement to stock individual components.

     Prepaid expenses decreased $8,000, or 4%, from $201,000 to $193,000.  The
decrease was primarily a result of the timing of downpayments for insurance
policies and amortization of prepaid expense items.

     Equipment and fixtures increased $38,000, or 7%, due to the acquisition of
equipment with cost of $143,000, which was mostly offset by depreciation of
$176,000.  The purchased equipment primarily consisted of office equipment and
workstations.

     Accounts payable decreased $629,000, or 34%, from $1,843,000 to $1,214,000,
due to decreased purchasing of inventory and a shortening of the payables cycle
that the Company was able to effectuate with the proceeds from the sale of
preferred stock and the exercise of options and warrants during the nine months
ended December 31, 1996.

     Accrued expenses decreased $221,000, or 24%, from $908,000 to $687,000.
The decrease was primarily due to the payment of a lawsuit settlement and
payment of a portion of the accrued severance pay to two former officers.

     Short term borrowings decreased by $938,000 due to the repayment and
termination of the line-of-credit financing agreement with Deutsche Financial
Services.

     Capital lease obligations decreased $6,000, or 13%, from $48,000 to
$42,000.  The decrease was the result principal payments of $28,000, which were
mostly offset by the addition of an office equipment lease in the amount of
$22,000.

     Series B Preferred Stock decreased $1,294,000 due to the conversion of all
outstanding shares of Series B Preferred Stock into 1,024,768 shares of common
stock.

     Series D Preferred Stock increased $2,342,000 due to the sale of 2,496
shares of Series D Preferred Stock, $1,000 per share stated value, during
December 1996.

     Additional paid in capital increased $5,000 as a result of warrants issued
in connection with the placement of the Series D Preferred Stock in December
1996.

     Common stock increased $3,528,000 due to the conversions of Series B
Preferred Stock, the issuance and subsequent conversion of Series C Preferred
Stock, the exercise of options and warrants and the payment of dividends on
preferred stock through the issuance of common stock.

     The accumulated deficit increased by $2,397,000 due to the net loss of
$2,316,000 recorded for the nine months ended December 31, 1996 and the payment
or accrual of $81,000 of dividends on preferred stock.

Liquidity
- ---------

     As of December 31, 1996, the Company had working capital of $5,649,000.
The Company currently relies on liquid assets to fund operations.  In July 1996,
the Company reduced its workforce in connection with a restructuring to allow
for greater conservation of liquid resources and the outsourcing of a greater
portion of the manufacturing activities.  The Company believes that the
outsourcing of manufacturing will allow the Company to respond more rapidly to
changes in sales volume, reduce the 

                                    Page 12

                                 CHATCOM, INC.

amount of inventory on hand and realize cost savings by utilizing the purchasing
power of the Company's subcontractors for component purchases.

     The Company believes that the capital resources that it currently possesses
would be sufficient to sustain operations at current revenue levels for only
approximately the next twelve months.  However, the Company's plan of operations
anticipates increasing revenues through penetration of the server consolidation
market, a focused marketing program and product improvements, which should
decrease the rate of utilization of capital resources. There can be no
assurance, however, that the Company will be successful in its efforts to
increase revenues or that any increase in revenues will enable the Company to
sustain its operations for more than the next twelve months without additional
capital resources. Additional capital resources might be obtained through the
calling or the voluntary exercise of warrants that were issued in conjunction
with the Company's 1995 private placement. The exercise of these warrants could
yield proceeds of up to $4,820,000. The Company may call these warrants for
redemption at $2.80 per warrant if the market value of the Company's common
stock has been greater than $3.60 per share for ten consecutive trading days. As
of the date of this report, the conditions necessary for the Company to call the
warrants have not been satisfied. To the extent required, the Company may also
seek additional public or private financing to meet its capital needs if market
conditions permit.

     The Company has incurred operating losses in each of its last three fiscal
years.  Should the Company continue to experience operating losses in the future
which result in a significant utilization of liquid resources, the Company's
liquidity and its ability to sustain operations at current levels could be
materially, adversely affected.  Should the Company experience significant
growth in revenues that requires the utilization of significant liquid resources
for the financing of increased accounts receivable and inventory balances, the
Company may seek a new line-of-credit financing agreement to assist in meeting
such cash requirements.  The Company does not currently have a commitment from
any third party to provide short-term financing.

     The Company had no material commitments for capital expenditures as of
December 31, 1996.

PART II     OTHER INFORMATION

ITEM 2.   CHANGES IN SECURITIES

     On December 13, 1996, the Company completed a private placement pursuant to
which it sold 2,496 shares of the Company's Series D 10% convertible redeemable
voting preferred stock, $1,000 stated value per share ("Series D Preferred
Stock"), and warrants to purchase 400,000 shares of the Company's common stock
(the "Warrants") to two institutional investors.  The Series D Preferred Stock
and the Warrants were exempt from registration requirements of the Securities
Act of 1933 (the "Securities Act") pursuant to Regulation D promulgated under
the Securities Act.  The Company received various representations and warranties
from the purchasers including a representation that the purchasers are
"accredited investors" within the meaning of Regulation D.  The Warrants are
exercisable commencing on May 1, 1997 through December 31, 2001 at $3,125 per
share.  Gross proceeds from this private placement were $2,500,000 and total
offering fees and costs incurred by the Company consisted of approximately
$153,000 in cash and warrants to purchase 100,000 shares of the Company's common

                                    Page 13

                                 CHATCOM, INC.

stock exercisable at $3.125 per share, of which $125,000 in cash and warrants to
purchase 100,000 shares of the Company's common stock were paid to Strategic
Growth International, Inc.  There were no underwriters or placement agents
involved in connection with the private placement.

     The proceeds from the placement will be utilized to provide working capital
for operations.

     The Company can require the holders of the Series D Preferred Stock to
convert these shares into shares of the Company's common stock at any time prior
to December 14, 1997 by acquiring the shares of Series D Preferred Stock from
the holders in exchange for shares of the Company's common stock.  The Series D
Preferred Stock is also convertible at the election of the holders into shares
of the Company's common stock during the one-year period commencing on December
14, 1997.  The actual number of shares of common stock into which the Series D
Preferred Stock and any dividends that are payable in shares of common stock are
convertible is variable, with the conversion value of the shares of common stock
being equal to the market price of the common stock (determined based on the
closing sale price of the common stock for the ten trading days preceding the
date of conversion).  The conversion value of the common stock will have a cap
of $4.50 per share, and commencing on December 14, 1997, will have a floor of
$1.50 per share.  The Company has agreed to register the shares issuable upon
conversion of the Series D Preferred Stock or upon exercise of the Warrants.

     The purchasers of the Series D Preferred Stock will have voting rights for
each share of the Series D Preferred Stock then outstanding equivalent to that
of 380 shares of common stock for each share of such preferred stock.  Holders
of the Series D Preferred Stock also will have the right to elect a majority of
the Company's directors in the event of a default by the Company in the payment
of dividends on the Series D Preferred Stock or upon certain other defined
events of default.

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

     Section 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 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

                                       2
<PAGE>
 
newspaper of general circulation in the county which 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.

     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 these shall be available to the shareholder on written demand
of the shareholders at the principal executive office of the corporation for a
period of one 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 shall be executed by the secretary, assistant secretary,
or any transfer agent of the corporation giving the notice, and shall be filed
and maintained in the minute book of the corporation.

     Section 6.  QUORUM.  The presence in person or by proxy of the holders of a
one-third (1/3) of the shares entitled to vote at any meeting of shareholders
shall constitute a quorum for the transaction of business. The shareholders
present at a duly called or held meeting at which a quorum is present may
continue to do business until 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.

     Section 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 6 of this
Article II.

     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 the board of directors shall set a new record
date. 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 4 and 5 of this Article II. At any adjourned meeting the
corporation may transact any business which might have been transacted at the
original meeting.

                                       3
<PAGE>
 
     Section 8.  VOTING.  The shareholders entitled to vote at any meeting of
shareholders shall be determined in accordance with the provisions of Section 11
of this Article II, subject to the provisions of Sections 702 and 704,
inclusive, of the Corporations Code of California (relating to voting shares
held by a fiduciary, in the name of the 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 elections 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 is voting affirmatively, it will be conclusively presumed that the
shareholder's approving vote is with respect to all shares that the shareholder
is entitled to vote. If a quorum is present, the affirmative vote of the
majority of the shares represented at the meeting and entitled to vote on any
matter (other than the election of directors) shall be the act of the
shareholders, unless the vote of a greater number or voting by classes is
required by California General Corporation Law 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 one or more
candidates a number of votes greater than the number of the shareholder's
shares) unless the candidates' names have been placed in nomination prior to
commencement of the voting and a shareholder's intentions to cumulate votes for
candidates 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.

     Section 9.  WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS. 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 or by proxy, signs a written waiver of
notice or a consent to a holding of the meeting or an approval of the minutes.
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 4 of this Article II,
the waiver of notice or consent shall state the general nature of the proposal.
All 

                                       4
<PAGE>
 
such waivers, consents or 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 at 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 matters not included in the notice
of the meeting if that objection is expressly made at the meeting.

     Section 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; provided,
however, that a director may be elected at any time to fill a vacancy on the
board of directors that has not been filled by the directors, by the written
consent of the holders of a majority of the outstanding shares entitled to vote
for the election of directors. All such consents shall be filed with the
secretary of the corporation and shall be maintained in the corporate records.
Any shareholder giving a written consent, of 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.
This notice shall be given in the manner specified in Section 5 of this Article
II. In the case of approval of (i) contracts or transactions in which a director
has a direct or indirect financial interest, pursuant to Section 3io of the
Corporations Code of California, (ii) indemnification of agents of organization
of the corporation, pursuant to Section 317 of that Code, (iii) a reorganization
of the corporation, pursuant to Section 1201 of that Code and (iv) a
distribution in dissolution other than in accordance with the rights of
outstanding preferred shares, pursuant to Section 2007 of that Code, the notice
shall be given at least ten (10) days before the consummation of any action
authorized by that approval.

     Section 11.  RECORD DATE FOR SHAREHOLDER NOTICE, VOTING AND GIVING
CONSENTS.  For purposes of determining the shareholders entitled to notice of
any 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 this 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 California General
Corporation Law.

     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 closed of business on the business day next preceding the day on
which the meeting is held.

     (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 of the board has been taken, shall be at the
close of business on 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 first.

     Section 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 by
shareholder's attorney-in-fact. A validly executed proxy which does not state
that it is irrevocable shall continue in full force and effect unless (i) a
writing delivered to the corporation stating that the proxy is revoked, or by a
subsequent proxy executed by, or attendance at the 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 Corporations Code of California.

     Section 13.  INSPECTORS OF ELECTION.  Before any meeting of shareholders,
the board of directors may appoint any persons other than nominees for office to
act as inspectors of election at the meeting or its adjournment. If no
inspectors of election are so appointed, the chairman of the meeting may, and on
the request of any shareholder or a shareholder's proxy shall, appoint
inspectors of election at the meeting. The number of inspectors shall be either
one (1) or three (3). If inspectors are appointed at a meeting on the request of
one 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.

     These inspectors shall:
 
     (a) Determine the number of shares outstanding and the voting power of
each, the 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 results; and

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

                                  ARTICLE III

                                   DIRECTORS

     Section 1.  POWERS.  Subject to the provisions of the California General
Corporation Law and any limitations in the Articles of Incorporation and these
bylaws 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.

     Section 2.  NUMBER AND QUALIFICATION OF DIRECTORS.  The number of directors
of the corporation shall not be less than five (5) nor more than nine (9). The
exact number of directors shall be eight (8) until changed, within the limits
specified 

                                       7
<PAGE>
 
above, 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 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 16-2/3 percent of the
outstanding shares entitled to vote. No amendment may change the stated maximum
number of authorized directors to a number greater than two times the stated
minimum number of directors minus one.

     Section 3.  ELECTION AND TERM OF OFFICE OF DIRECTORS. Directors shall be
elected at each annual meeting of the shareholders to hold office until the next
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.

     Section 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 shares entitled to vote
represented at a duly held meeting at which a quorum is present, or by the
written consent of holders of a majority of the outstanding shares entitled to
vote. Each director so elected shall hold office until the next annual meeting
of the shareholders or 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 unauthorized number of directors is increased, of 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 voted for at that meeting.

     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 by
written consent shall require the consent of a majority of the outstanding
shares entitled to vote.

     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 specified a later time 

                                       8
<PAGE>
 
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.

     Section 5.  PLACE OF MEETINGS AND 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 meeting shall be held at

     Section 6.  ANNUAL MEETING.  Immediately following each annual meeting of
shareholders, the board of directors shall hold a regular meeting for the
purpose of organization, and desired election of officers, and the transaction
of other business. Notice of this meeting shall not be required.

directors shall be held without call at such time as shall from time to time be

for any purpose or purposes may be called at any time by the chairman of the
board or the president or any vice president or the secretary or any two

as it is shown in the records of the corporation. In case the notice is mailed,
it shall be deposited in the United States mail at least four days before the

     Section 9.  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 11 of this Article III. Every act or decision done or made
by a majority of the directors present at a meeting duly held at which a quorum
is present shall be regarded as the act of the board of directors.

     Section 10.  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. 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.

not constituting a quorum, may adjourn any meeting to another time and place.

     Section 12.  NOTICE OF ADJOURNMENT.  Notice of the time and place of

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 8 of this Article III, to the directors who were not present at the
time of adjournment.

     Section 13.  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 or consents
shall be filed with the minutes of the proceedings of the board.

     Section 14.  TELEPHONE CONFERENCE.  Members of the board may participate in
a meeting through use of conference telephone or similar communications
equipment, so long as all members participating in such meeting can hear one
another. Participation in a meeting pursuant to this subdivision constitutes

committees may receive such compensation, if any, for their services, and such
reimbursements of expenses, as may be fixed or determined by resolution of the
board of directors. This Section 15 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.

such person was unlawful.

     The termination of any proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent shall not, of

conduct was unlawful.

Corporation, against expenses actually and reasonably incurred by such person in
connection with the defense or settlement of such action if such person acted in
good faith, in a manner such person believed to be in the best interests of the
Corporation and its Shareholders.

     No indemnification shall be made under this Section 6.3 for any of the
following:

          (a) Any claim, issue, or matter as to which such person shall have
been adjudged to be liable to the Corporation in the performance of such
person's duty to the Corporation and its Shareholders, unless and only to the
extent that the court in which such proceeding is or was pending shall determine
upon application that, in view of all the circumstances of the case, such person
is fairly and reasonably entitled to indemnity for the expenses which such court
shall determine;

          (b) Amounts paid in settling or otherwise disposing of a pending
action, without court approval; or

          (c) Expenses incurred in defending a pending action which is settled
or otherwise disposed of without court approval.

     Section 6.4.  INDEMNIFICATION AGAINST EXPENSES.  To the extent that an
agent of the Corporation has been successful on the merits in defense of any
proceeding referred to in Sections 6.2 or 6.3 of this Article or in defense of
any claim, issue or matter therein, the agent shall be indemnified against
expenses actually and reasonably incurred by the agent in connection therewith.

     Section 6.5.  REQUIRED DETERMINATIONS.  Except as provided in Section 6.4
of this Article, any indemnification under this Article shall be made by the
Corporation only if authorized in the specific case, upon a determination that
indemnification of the agent is proper in the circumstances because the agent
has met the applicable standard of conduct set forth in Sections 6.2 and 6.3 of
this Article by:

          (a) A majority vote of a quorum consisting of Directors who are not
parties to such proceeding;

          (b) If such a quorum of Directors is not obtainable, by independent
legal counsel in a written opinion;

          (c) Approval of the Shareholders, with the shares owned by the person
to be indemnified not being entitled to vote thereon; or

          (d) The court in which such proceeding is or was pending upon
application made by the Corporation or the agent or the attorney or other person
rendering services in connection with the defense, whether or not such
application by the agent, attorney, or other person is opposed by the
Corporation.

     Section 6.6.  ADVANCE OF EXPENSES.  Expenses incurred in defending any
proceeding may be advanced by the Corporation prior to the final disposition of
such proceeding upon receipt of an undertaking by or on behalf of the agent to
repay such amount unless it shall be determined ultimately that the agent is
entitled to be indemnified as authorized in this Article.

     Section 6.7.  NONEXCLUSIVE PROVISIONS.  The indemnification authorized by
this Article shall not be deemed exclusive of any additional rights to
indemnification for breach of duty to the Corporation and its Shareholders while
acting in the capacity of a Director or Officer of the Corporation to the extent
the additional rights to indemnification are authorized in an article provision
adopted pursuant to California Corporations Code Section 204(a)(11).  The
indemnification provided by this Article for acts, omissions, or transactions
while acting in the capacity of, or while serving as, a Director or Officer of
the Corporation but not involving breach of duty to the Corporation and its
Shareholders 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 

                                       16
<PAGE>
 
directors, or otherwise, to the extent the additional rights to indemnification
are authorized in the Articles.

     An Article provision authorizing indemnification "in excess of that
otherwise permitted by Corporations Code Section 317" or "to the fullest extent
permissible under California law" or the substantial equivalent thereof shall be
construed to be both a provision for additional indemnification for breach of
duty to the Corporation and its Shareholders as referred to in, and with the
limitations required by, California Corporations Code Section 204(a)(11), and a
provision for additional indemnification as referred to in the second sentence
of the first paragraph of this Section.

     The rights to indemnity hereunder shall continue for a person who has
ceased to be a Director, Officer, employee, or agent and shall inure to the
benefit of the heirs, executors, and administrators of the person.  Nothing
contained in this Article shall affect any right to indemnification to which
persons other than the Directors and Officers may be entitled by contract or
otherwise.

     Section 6.8.  FORMS OF INDEMNIFICATION NOT PERMITTED.  No indemnification
or advance shall be made under this Article, except as provided in Section 6.4
or Section 6.5(d) of this Article in any circumstance where it appears:

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

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

     Section 6.9.  INSURANCE.  The Corporation shall have power to purchase and
maintain insurance on behalf of any agent of the Corporation against any
liability asserted against or incurred by the agent in such capacity or arising
out of the agent's status as such whether or not the Corporation would have the
power to indemnify the agent against such liability under the provisions of this
Article.

     Section 6.10.  NONAPPLICABILITY TO FIDUCIARIES OF EMPLOYEE BENEFIT PLANS.
This Article does not apply to any proceeding against any trustee, investment
manager, or other fiduciary of an employee benefit plan in such person's
capacity as such, even though such person may also be an agent of the
Corporation as defined in Section 6.1 of this Article.  The Corporation shall
have power to indemnify such trustee, investment manager or other fiduciary to
the extent permitted by subdivision (f) of Section 207 of the California
Corporations Code.

                                  ARTICLE VII

                              RECORDS AND REPORTS

     Section 1.  MAINTENANCE AND INSPECTION OF SHARE REGISTER.  The corporation
shall keep at its principal executive office, or at the office of its transfer
agent or registrar, if either be appointed and as determined by resolution of
the board of directors, a record of its shareholders, giving the names and
addresses of all shareholders and the number and class of shares held by each
shareholder.

     A shareholder or shareholders of the corporation holding at least five
percent (5%) in the aggregate of the outstanding voting shares of the
corporation may (i) inspect and copy the records of shareholders' names and
addresses and shareholdings during usual business hours on five (5) days' prior
written demand on the corporation, and (ii) obtain from the transfer agent of
the corporation, on written demand and on the tender of such transfer agent's
usual charges for such list, a list of the shareholders' names and addresses,
who are entitled to vote for the election of directors, and their shareholdings,
as of the most recent record date for which the list has been compiled or as of
a date specified in by the shareholder after the date specified in the demand.
This 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 the date
specified in the demand of any shareholder or holder of a voting trust
certificate, at any time during usual business hours, for a purpose reasonably
related to the holder's interest as a shareholder or as the holder of voting
trust certificate. Any inspection and copying under this Section 1 may be made
in person or by an agent or attorney of the shareholder or holder of a voting
trust certificate making the demand.

     Section 2.  MAINTENANCE AND INSPECTION OF BYLAWS.  The corporation shall
keep at its principal executive office, or if its principal executive office is
not in the State of California, at its principal business office in this state,
the original or a copy of the bylaws as amended to date, which shall be open to
inspection by the shareholders at all reasonable times during office hours. If
the principal executive office of the corporation is outside the State of
California and the corporation has no principal business office in this state,
the secretary shall, upon the written request of any shareholder, furnish to
that shareholder a copy of the bylaws as amended to date.

     Section 3.  MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS.  The
accounting books and records and minutes of any proceedings of the shareholders
and the board of directors and any committee or committees of the board of
directors shall be kept at such place or places designated by the board of
directors, or, in the absence of such designation, at the 

                                       18
<PAGE>
 
principal 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.
The inspection may be made in person or by an agent or attorney, and shall
include the right to copy and make extracts. These rights of inspection shall
extend to the records of each subsidiary corporation of the corporation.

     Section 4.  INSPECTION BY DIRECTORS.  Every director shall have the
absolute right at any reasonable time to inspect all books, records, and
documents of every kind and the physical properties of the corporation and each
of its subsidiary corporations. This inspection by a director may be made in
person or by an agent or attorney, and the right of inspection includes the
right to copy and make extracts of documents.

     Section 5.  ANNUAL REPORT TO SHAREHOLDERS.  The annual report to the
shareholders referred to in Section 1501 of the California General Corporation
Law is expressly dispensed with, but nothing herein shall be interpreted as
prohibiting the board of directors from issuing annual or other periodic reports
to the shareholders of the corporation as they may consider appropriate.

     Section 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 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 years this report shall likewise be delivered or mailed to the
shareholder or shareholders within thirty (30) days after the request.

                                       19
<PAGE>
 
     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.

     Section 7.  ANNUAL STATEMENT OF GENERAL INFORMATION.  The corporation shall
file with the Secretary of State of California, on the prescribed form, a
statement setting forth the authorized number of directors, the names and
complete business or residence addresses of all directors, the names and
complete business or residence addresses of all incumbent directors, the names
and complete business or residence addresses of the chief executive officer,
secretary and chief financial officer, the street address of its principal
executive office or principal business office in this state, and the general
type of business constituting the principal business activity of the
corporation, together with a designation of the agent of the corporation for the
purpose of service of process, all in compliance with Section 1502 of the
Corporations Code of California.

                                  ARTICLE VIII

                           GENERAL CORPORATE MATTERS

     Section 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 to any 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
before any such action, and in that case only shareholders of record on the date
so fixed are entitled to receive the dividend, distribution, or allotment of
rights or to exercise the 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 California General Corporation Law.

     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.

     Section 2.  CHECKS, DRAFTS, EVIDENCES OF INDEBTEDNESS.  All checks, drafts,
or other orders for payment of money, notes, or 

                                       20
<PAGE>
 
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.

     Section 3.  CORPORATE CONTRACTS AND INSTRUMENTS; HOW EXECUTED.  The board
of directors, except as otherwise provided in these bylaws, may authorize any
officer or officers, agent or agents, to enter into any contract or execute any
instrument in the name or on behalf of the corporation, and this authority may
be general or confined to specific instances; and, unless so authorized or
ratified by the board of directors 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.

     Section 4.  CERTIFICATES OF SHARES.  A certificate or certificates for
shares of the capital stock of the corporation shall be fully paid, and the
board of directors may authorize the issuance of certificates for shares as
partly paid provided that these certificate 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 vice president and by the chief
financial officer or an assistant treasurer or the secretary or any 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, 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.

     The corporation shall have the right to impose restrictions on the sale or
other disposition of its shares which restrictions may be placed upon all or a
portion or portions of the certificates evidencing the corporation's shares to
which such restrictions apply.

     Section 5.  LOST CERTIFICATES.  Except as provided in this Section 5, no
new certificate for shares shall be issued to replace an old certificate unless
the latter is surrendered to the corporation and cancelled 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 a
replacement certificate 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 

                                       21
<PAGE>
 
of the certificate or the issuance of the replacement certificate.

     Section 6.  REPRESENTATION OF SHARES OF OTHER CORPORATIONS. The chairman of
the board, the president, or any vice president, or any other person authorized
by resolution of the board of directors or by any of the foregoing designated
officers, is authorized to vote on behalf of the corporation any and all shares
of any other corporation or corporations, foreign or domestic, standing in the
name of the corporation. The authority granted to these officers to vote or
represent on behalf of the corporation any and all shares held by the
corporation in any other corporation or corporations may be exercised by any of
these officers in person or by any person authorized to do so by a proxy duly
executed by these officers.

     Section 7.  CONSTRUCTION AND DEFINITIONS.  Unless the context requires
otherwise, the general provisions, rules of construction, and definitions in the
California General Corporation Law shall govern the construction of these
bylaws. Without limiting the generality of this provision, the singular number
includes the plural, the plural number includes the singular, and the term
"person" includes both a corporation and a natural person.

                                   ARTICLE IX

                                   AMENDMENTS

     Section 1.  AMENDMENT BY SHAREHOLDERS.  New bylaws may be adopted or these
bylaws may be amended or repealed by the vote or written consent of holders of a
majority of the outstanding shares entitled to vote; provided, however, that if
the articles of incorporation of the corporation set forth the number of
authorized directors of the corporation, the authorized number of directors may
be changed only by an amendment to the articles of incorporation. '

     Section 2.  AMENDMENT BY DIRECTORS.  Subject to the rights of the
shareholders as provided in Section 1 of this Article IX, bylaws, other than a
bylaw or an amendment of a bylaw changing the authorized number of directors,
may be adopted, amended, or repealed by the board of directors.

The Company agrees to remove the foregoing legend from any certificate
evidencing Conversion Shares if the Conversion Shares represented by such
certificate have been registered with the Commission pursuant to the Securities
Act and the Purchaser agrees to comply with applicable prospectus delivery and
black-out period requirements, or Rule 144(k) under the Securities Act (or any
successor rule or regulation) is then applicable to such Conversion Shares.

                  (b) Each Purchaser understands that each Preferred Stock
certificate purchased by each Purchaser will be endorsed with the following
legend:

          THE SECURITIES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF
          THE COMPANY TO PURCHASE SUCH SECURITIES, UNTIL DECEMBER , 1997, WHICH
          RIGHT IS DESCRIBED IN SECTION 6.1(a) OF THE PURCHASE AGREEMENT DATED
          AS OF DECEMBER 9, 1996 BETWEEN THE COMPANY AND INITIAL PURCHASER OF
          SUCH SECURITIES. A COPY OF SUCH PURCHASE AGREEMENT IS ON FILE AT THE
          PRINCIPAL OFFICE OF THE COMPANY.

            5.5.  Economic Risk.  Each Purchaser hereby severally and not 
                  -------------                                          
jointly represents that such Purchaser is capable of evaluating the risk of his
investment in the Preferred Stock and Warrants and is able to bear the economic
risk of such investment, that such Purchaser is an "accredited investor" within
the meaning of Regulation D under the Securities Act, and that the Company has
made available all additional information which such Purchaser has requested and
that such Purchaser has had the opportunity to ask questions of and receive
complete and satisfactory answers from the Company concerning an investment in
the Preferred Stock and Warrants.

            5.6.  Restricted Securities.  Such Purchaser understands that the
                  ---------------------                                  
Preferred Stock and Warrants, together with any of the Conversion Shares
available upon conversion, it is purchasing are characterized as "restricted
securities" under the federal securities laws inasmuch as they are being
acquired from the Company in a transaction not involving a public offering and
that under such laws and applicable regulations such securities may be resold
without registration under the Securities Act only in certain limited
circumstances, and it represents that it is familiar with Commission Rule 144,
as presently in effect, and understands the resale limitations imposed thereby
and by the Securities Act.

            5.7.  Address.  Such Purchaser's principal address is as set forth
                  -------

     SECTION 6.  OPTIONAL REDEMPTION; CONVERSION

                 6.1. Conversion.
                      ---------- 

                      (a) The Company shall have the right, at the option of the
Company, at any time on or prior to the first anniversary of the Closing Date,
to purchase, subject to the terms and provisions of this Section 6 and provided
that no Event of Noncompliance or Potential Noncompliance shall have occurred
and be continuing, all (but not less than all) Outstanding shares of Preferred
Stock from all of the Purchasers. The purchase price for such Preferred Stock
shall be payable in Conversion Shares in an amount determined by dividing the
product of $1,000 times the number of shares of Preferred Stock to be purchased
by the Conversion Price in effect on the applicable Conversion Date, calculated
to the nearest Conversion Share (fractions of less than 1/2 being disregarded
and fractions of 1/2 or greater being rounded up to the next

                                      15
<PAGE>
 
full share).  Such right to purchase shall be exercised by delivery by the
Company to each Purchaser of written notice of the Company's election to
purchase the Preferred Stock, which notice shall specify a Conversion Date on or
prior to the first anniversary of the Closing Date.  Promptly upon receipt by a
Purchaser of such written notice, such Purchaser shall deliver the certificates
evidencing Preferred Stock held by such Purchaser to the Company at the office
of the Company provided for in Section 7.6.

                      (b) Each holder of Preferred Stock shall have the right,
at the option of such holder, at any time after the first anniversary of the
Closing Date through and including the second anniversary of the Closing Date to
convert, subject to the terms and provisions of this Section 6, all or any
portion of such Preferred Stock into Conversion Shares. Such conversion of
Preferred Stock into Conversion Shares shall be made at the Conversion Price in
effect on the Conversion Date. Such right of conversion shall be exercised by
delivery of the certificates evidencing Preferred Stock to the Company at the
office of the Company provided for in Section 7.6, accompanied by written notice
of the holder's election to convert the Preferred Stock or specified portion
thereof, which such notice shall specify the Conversion Date.

                      (c) The holder of a Warrant shall have the right, at the
option of such holder, at any time after April 30, 1997 through and including
the Warrant Expiration Date to exercise, subject to the terms and provisions of
this Section 6, such Warrant or any portion thereof into Conversion Shares. Such
exercise of Warrants for Conversion Shares shall be made at the Exercise Price.
Such right of exercise shall be exercised by delivery of the Warrant to the
Company at the office of the Company provided for in Section 7.6, accompanied by
written notice of the holder's election to exercise the Warrant or portion
thereof, which notice shall specify the Conversion Date.

                      (d) For convenience, the conversion by the holders of the
Preferred Stock pursuant to Section 6.1(b) or the purchase by the Company
pursuant to Section 6.1(a), as the case may be, of all or a portion of the
Preferred Stock into, or in exchange for, Conversion Shares is herein sometimes
referred to as the "conversion" of the Preferred Stock, and the exercise of all
                    ----------
or a portion of a Warrant into Conversion Shares pursuant to Section 6.1(c) is
herein sometimes referred to as the "conversion" of the Warrant.
                                     ----------                 

            6.2.  Delivery of Stock Certificates; Time Conversion Effective.
                  ---------------------------------------------------------

                  (a) As promptly as practicable after the surrender as herein
provided of a certificate evidencing Preferred Stock or Warrant for conversion,
the Company shall deliver or cause to be delivered to or upon the written order
of the holder of certificate evidencing Preferred Stock or Warrant so
surrendered certificates representing the number of fully paid and non-
assessable Conversion Shares into which the Preferred Stock or Warrant, or such
portion thereof, may be converted in accordance with the provisions of this
Section 6. In the case of the conversion of Preferred Stock,

                                      16
<PAGE>
 
such number shall be determined by dividing the product of $1,000 times the
number of shares of Preferred Stock to be converted by the Conversion Price on
the applicable Conversion Date, calculated to the nearest Conversion Share
(fractions of less than 1/2 being disregarded and fractions of 1/2 or greater
being rounded up to the next full share).  If only a fraction of the number of
shares of Preferred Stock or Warrants are used in such conversion, the Company
shall, concurrently with the issuance of the Conversion Shares issuable upon
such conversion, take the action described in Section 12(b) hereof.

                      (b) Subject to the following provisions of this Section
6.2, such conversion shall be deemed to have been made at the close of business
on the Conversion Date specified in the applicable Conversion Notice, so that
the rights of the holder of the Preferred Stock or the Warrant as a holder
thereof, or such portion thereof, shall cease at such time and the Person or
Persons entitled to receive any of the Conversion Shares upon conversion of the
Preferred Stock or the Warrant shall be treated for all purposes as having
become the record holder or holders of such Conversion Shares at such time.

                      (c) The Company will, at the time of such conversion, in
whole or in part, upon request of the holder of the Preferred Stock or the
Warrant, acknowledge in writing its continuing obligation to such holder in
respect of any rights (including, without limitation, any right of registration
of the Conversion Shares issued upon such conversion) to which such holder shall
continue to be entitled under this Agreement after such conversion, provided
that the failure of such holder to make any such requests shall not affect the
continuing obligation of the Company to such holder in respect of such rights.

            6.3.  Payment of Dividends Upon Conversion.
                  ------------------------------------ 

            The Company shall pay all unpaid dividends on any Preferred Stock so
converted which has accrued through and including the date upon which such
conversion is deemed to have been effected in accordance with Section 6.2
hereof, such payment to be made in cash or in Conversion Shares (calculated at
the Conversion Price then in effect) at the Company's option.

            6.4.  Adjustment of Exercise Price, Floor Price and Cap Price.
                  -------------------------------------------------------  
The Exercise Price, Floor Price and Cap Price shall be subject to adjustment,
from time to time, as follows:

                  (a) In case the Company shall, after the Closing Date, (i) pay
a stock dividend or make a distribution in shares of its capital stock (whether
of Shares or of capital stock of any other class), (ii) subdivide its
Outstanding Shares, (iii) combine its Outstanding Shares into a smaller number
of Shares or (iv) issue by reclassification of its Shares, any shares of capital
stock of the Company, the Exercise Price of the Warrants and the Floor Price and
the Cap Price of the Preferred Stock shall be adjusted so that (A) the holder of
a Warrant thereafter surrendered for conversion shall be entitled to receive the
number of shares of capital stock of the Company which

                                      17
<PAGE>
 
he would have owned immediately following such action had such Warrant been
converted immediately prior thereto, and (B) the Floor Price and the Cap Price
of the Preferred Stock shall be appropriately adjusted, and such conversion
price, Floor Price and Cap Price shall thereafter be subject to further
adjustments under this Section 6. An adjustment made pursuant to this subsection
(a) shall become effective retroactively immediately after the record date in
the case of a dividend or distribution and shall become effective immediately
after the effective date in the case of a subdivision, combination or
reclassification.

                      (b) In case the Company shall, after the Closing Date, fix
a record date for the making of a distribution to all holders of its Shares
(including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing corporation) of (i) assets (other
than dividends payable in Shares), (ii) evidences of indebtedness or other
securities (except for Shares) of the Company or of any corporation other than
the Company, or (iii) subscription rights, options or warrants to purchase any
of the foregoing assets or securities (excluding those referred to in Section
6.4(d)(3) hereof), whether or not such rights, options or warrants are
immediately exercisable (hereinafter collectively referred to as "Distributions
                                                                  -------------
on Common Stock"), the Company shall promptly notify each Purchaser thereof in
- ---------------
writing (such notice to be given at least ten (10) Business Days prior to such
record date) and shall issue to the holders of Outstanding Preferred Stock, the
Distribution on Common Stock to which they would have been entitled if they had
converted the Preferred Stock held by them into Common Stock of the Company
immediately prior to the record date for the purpose of determining stockholders
entitled to receive such Distribution on Common Stock.

                      (c) Subject to the exceptions referred to in Section
6.4(e) hereof, in case the Company shall at any time or from time to time after
the Closing Date issue any additional Shares ("Additional Common Stock") for a
                                               ----------------------- 
consideration per share either (I) less than the then current Market Price per
share of Common Stock of the Company (determined as provided in Section 6.4(g)
hereof) immediately prior to the issuance of such Additional Common Stock, (II)
less than the then current Exercise Price immediately prior to the issuance of
such Additional Common Stock, or (III) without consideration, then (in the case
of either clause (I), (II) or (III)), and thereafter successively upon each such
issuance, the then current Exercise Price and Floor Price shall be reduced, if
necessary, (but not increased) to the price determined by multiplying such
current Exercise Price or Floor Price, as the case may be, by a fraction, of
which

                          (A) the numerator shall be (i) the number of Shares
     Outstanding when the then current Exercise Price or Floor Price, as the
     case may be, became effective plus (ii) the number of Shares which the
     aggregate amount of consideration, if any, received by the Company upon all
     issues of its Common Stock (other than those referred to in Section 6.4(e)
     hereof) since the then current Exercise Price or Floor Price, as the case
     may be, became effective (including the consideration, if any, received for
     such Common Stock) would

                                      18
<PAGE>
 
     purchase at the greater of (A) the then current Market Price per Share of
     Common Stock of the Company or (B) the then current Exercise Price or Floor
     Price, as the case may be, and

                          (B) the denominator shall be (i) the number of Shares
     Outstanding when the then current Exercise Price or Floor Price, as the
     case may be, became effective plus (ii) the number of Shares issued (other
     than those referred to in Section 6.4(e) hereof) since the then current
     Exercise Price, or Floor Price, as the case may be, became effective
     (including the number of Shares of such Additional Common Stock).

                      (d) For purposes of Section 6.4(c) hereof, the following
provisions shall also be applicable:

                          (1) In case of the issuance of Additional Common Stock
     for cash, the consideration received by the Company therefor shall be
     deemed to be the net cash proceeds received by the Company for such
     Additional Common Stock after deducting any commissions or other expenses
     paid or incurred by the Company for any underwriting of, or otherwise in
     connection with the issuance of, such Additional Common Stock.

                          (2) in case of the issuance (otherwise than upon
     conversion of obligations or shares of stock of the Company) of Additional
     Common Stock for a consideration other than cash, or a consideration a part
     of which shall be other than cash, the amount of the consideration other
     than cash so received or to be received by the Company shall be deemed to
     be the value of such consideration at the time of its receipt by the
     Company as determined in good faith by the Board of Directors of the
     Company, except that where the non-cash consideration consists of the
     cancellation, surrender or exchange of outstanding obligations of the
     Company (or where such obligations are otherwise converted into Shares),
     the value of the non-cash consideration shall be deemed to be the amount,
     including principal and any accrued interest, as of the time of the
     Company's receipt, of the obligations canceled, surrendered, satisfied,
     exchanged or converted. If the Company receives consideration, part or all
     of which consists of publicly traded securities (i.e., in lieu of cash),
                                                      ---- 
     the value of such non-cash consideration shall be the aggregate market
     value of such securities (based on the latest reported trades) as of the
     close of the day immediately preceding the date of their receipt by the
     Company.

                          (3) in case of the issuance (other than by way of a
     Distribution on Common Stock pursuant to Section 6.4(b) hereof), whether by
     distribution or sale to holders of its Shares or to others, by the Company
     of (i) any security (other than the Preferred Stock or the Warrants) that
     is convertible into Shares or (ii) any rights, options or warrants to
     purchase Shares (except as stated in Section 6.4(a) hereof), the Company
     shall be deemed to have issued, for the consideration described below, the
     number of Shares into

                                      19
<PAGE>
 
     which such convertible security may be converted when first convertible, or
     the number of Shares deliverable upon the exercise of such rights, options
     or warrants when first exercisable, as the case may be (and such Shares
     shall be deemed to be Additional Common Stock for purposes of Section
     6.4(c) hereof); provided, that if such number of Shares is thereafter
     increased in accordance with the terms of such convertible security,
     rights, options or warrants, as a result of the anti-dilution provisions of
     such convertible security, rights, options or warrants or otherwise, the
     Company shall be deemed to have issued at the time of such increase and at
     no consideration, the additional Shares into which such convertible
     securities may be converted as a result of such increase or the additional
     Shares for which such rights, options or warrants may be exercised as a
     result of such increase, as the case may be.  The consideration to be
     deemed to be received by the Company at the time of the issuance of such
     convertible securities or such rights, options or warrants shall be the
     consideration so received determined as provided in Section 6.4(d)(1) and
     (2) hereof after deducting any commissions or other expenses paid or
     incurred by the Company for any underwriting of, or otherwise in connection
     with, the issuance of such convertible securities or rights, options or
     warrants, plus (x) any consideration or adjustment payment to be received
     by the Company in connection with such conversion, or (y) the aggregate
     price at which Shares are to be delivered upon the exercise of such rights,
     options or warrants when first exercisable or, if no price is specified and
     such Shares are to be delivered at an option price related to the market
     value of the Common Stock, an aggregate option price bearing the same
     relation to the market value of the Common Stock at the time such rights,
     options or warrants were granted; provided, that as to such rights, options
                                       --------                                 
     or warrants further adjustment as shall be necessary on the basis of the
     actual option price at the time of exercise shall be made at such time if
     the actual option price is less than the aforesaid assumed option price.
     No further adjustment of the Conversion Price or Exercise Price shall be
     made as a result of the actual issuance of Shares referred to in this
     paragraph (3).  If any rights or warrants which lead to an adjustment of
     the Exercise Price or the Floor Price expire or terminate without having
     been exercised, the Exercise Price or the Floor Price, as the case may be,
     then in effect will be appropriately readjusted.  However, a readjustment
     of the Exercise Price or the Floor Price will not affect any conversions
     which take place before the readjustment.

                          (4) In case any event shall occur as to which the
     provisions of paragraphs (1), (2) or (3) of this Section 6.4(d) are not
     strictly applicable but the failure to make any adjustment would not fairly
     protect the conversion rights represented by the Preferred Stock or the
     Warrants in accordance with the essential intent and principles of such
     subsections, then, in each such case, the Company shall, if requested by a
     Majority in Interest of Outstanding Preferred Stock or a Majority in
     Interest of Outstanding Warrants, at the expense of the Purchasers, appoint
     a firm of independent public accountants of recognized national standing
     selected by the Board of Directors of the Company (who may be the regular
     auditors of the Company), which shall give

                                      20
<PAGE>
 
     their good faith opinion upon the adjustment, if any, on a basis consistent
     with the essential intent and principles established in paragraphs (1), (2)
     or (3) of this Section 6.4(d), necessary to preserve, without dilution, the
     conversion rights represented by the Preferred Stock or the Warrants, as
     the case may be.  Such opinion upon such adjustment, if any, as may be
     necessary shall be final and binding on the parties hereto and all
     subsequent holders of Preferred Stock and/or Warrants.  Upon receipt of
     such opinion, the Company will promptly mail copies thereof to the holders
     of the Preferred Stock and the holders of the Warrants and shall make the
     adjustments described therein.

          (e) No adjustment of the Exercise Price or the Floor Price shall be
made as a result of or in connection with the issuance of Shares upon conversion
of the Preferred Stock or the Warrants or upon conversion of any convertible
securities outstanding as of the Closing Date or any options granted under the
Company's qualified stock option plans, all of which convertible securities and
stock option plans are set forth on Exhibit C hereto.  To the extent the
issuance (or deemed issuance) of Shares shall not result in any adjustment of
the Exercise Price or the Floor Price pursuant to the provisions of this Section
6.4(e), then such Shares shall not be taken into account for purposes of
determining the prices under Section 6.4(c) hereof.

          (f) Whenever the Conversion Price and/or the Floor Price and/or the
Cap Price and/or the Exercise Price is adjusted as provided in this Section 6.4,
the Company will promptly provide a certificate of its chief financial officer,
and, if requested by a Majority in Interest of Outstanding Preferred Stock or a
Majority in Interest of Outstanding Warrants, will promptly obtain a certificate
of a firm of independent public accountants of recognized national standing
selected by the Board of Directors of the Company (who may be the regular
auditors of the Company), setting forth the Conversion Price and/or the Floor
Price and/or the Cap Price and/or the Exercise Price as so adjusted and a brief
statement of facts accounting for such adjustment, and will mail a brief summary
thereof to the holders of the Preferred Stock and the holders of the Warrants.

          (g) For the purpose of any computation under this Section 6, the
current "Market Price" per share of Common Stock of the Company on any date
         ------------                                                      
shall be deemed to be the average of the Market Prices for the 10 consecutive
trading dates commencing 12 trading days before such date.

            6.5.  Company's Consolidation or Merger.  If the Company shall at
                  ---------------------------------                       
any time consolidate with or merge into another corporation (where the Company
is not the continuing corporation after such merger or consolidation), the
holder of Preferred Stock or a Warrant shall thereafter be entitled to receive,
upon the conversion thereof, the securities or property to which a holder of the
number of Conversion Shares then deliverable upon the conversion thereof would
have been entitled upon such consolidation or merger had such holder exercised
or converted immediately prior to such consolidation or merger (subject to
subsequent adjustments under Section 6.4 hereof), and the Company shall take
such steps in connection with such consolidation or merger as

                                      21
<PAGE>
 
may be reasonably necessary to assure such holder that the provisions of this
Agreement shall thereafter be applicable in relation to any securities or
property thereafter deliverable upon the conversion of the Preferred Stock and
the Warrants, including, but not limited to, obtaining a written acknowledgment
from the continuing corporation of its obligation to supply such securities or
property upon such conversion.  A sale of all or substantially all the assets of
the Company shall be deemed a consolidation or merger for the foregoing
purposes.

                 6.6. No Fractional Shares to be Issued.  No fractional
                      ---------------------------------                
Conversion Shares shall be issued on any conversion.

                 6.7. Taxes on Conversion.  The issuance of certificates for
                      -------------------                                   
Conversion Shares upon the conversion of Preferred Stock and/or Warrants shall
be made without charge to the holders of Preferred Stock or Warrants converting
such Preferred Stock or Warrants for any issue or stamp tax in respect of the
issuance of such certificates, and such certificates shall be issued in
respective names of, or in such names as may be directed by, the holders of the
Preferred Stock or the holders of the Warrants so converted.

                 6.8. Notice to Holders of Preferred Stock or Warrants.  In case
                      ------------------------------------------------          
at any time

                      (a) the Company shall take any action which would require
an adjustment in the Conversion Price, the Floor Price, the Cap Price or the
Exercise Price pursuant to Section 6.4(a) or (c) hereof; or

                      (b) the Company shall authorize the granting to the
holders of its Common Stock of any Distribution on Common Stock as set forth in
Section 6.4(b) hereof; or

                      (c) there shall be any capital reorganization or
reclassification of the Common Stock of the Company (other than a change in par
value or from par value to no par value or from no par value to par value of the

of the Preferred Stock or Conversion Shares so affected.  The Company agrees
that all holders of Preferred Stock shall be notified by the Company in advance

each holder of Preferred Stock then or thereafter Outstanding shall be bound by
any amendment or waiver effected in accordance with the provisions of this
Section 11, whether or not the certificates evidencing such Preferred Stock
shall have been marked to indicate such modification, but any Preferred Stock
issued thereafter shall bear a notation as to any such modification (but the
failure to bear any such notation shall not affect the validity of any such
subsequently issued Preferred Stock, which shall be enforceable in accordance

registered in the name of such person or persons as may be designated by such
holder for the same aggregate number of shares as the Preferred Stock

Preferred Stock so surrendered or (ii) new Warrants convertible into the same
aggregate number of Conversion Shares as the Warrant or Warrants surrendered and
substantially in the form thereof, dated the date of the Warrant or Warrants so
surrendered.  Any such new Preferred Stock shall bear any notation required by
Section 11 hereof.

          (b) Upon the conversion in whole or in part of any Preferred Stock or
any Warrant, if only a portion of the Preferred Stock or only a fraction of the
number of Conversion Shares subject to the Warrant is used in such conversion,
then the Company shall execute and deliver to or upon the order of the holder
thereof, at the expense of the Company, a new Preferred Stock certificate or
Preferred Stock certificates evidencing the unused portion of such Preferred
Stock or a new Warrant or Warrants convertible into the unused number of

theft, destruction or mutilation of any Preferred Stock certificate or Warrant
and, in the case of any such loss, theft or destruction, upon delivery of an
indemnity reasonably satisfactory to the Company (if requested by the Company),
or in the case of any such mutilation, upon surrender and cancellation of such
Preferred Stock certificate or Warrant, the Company will issue a new Preferred
Stock certificate or Warrant of like tenor in lieu of such lost, stolen,
destroyed or mutilated Preferred Stock or Warrant as if the lost, stolen,
destroyed or mutilated Preferred Stock certificate or Warrant were then
surrendered for exchange.  No Purchaser shall be required to furnish an
indemnity bond in connection with any such loss, theft or destruction.

     SECTION 14. EVENTS OF NONCOMPLIANCE

          If any of the following events (each herein called an "Event of
                                                                 --------

Purchaser; or

          (c) If the Company shall default in the performance of any agreement

          (d) If the Company shall default in any material respect in the
performance of any agreement or covenant, other than those referred to in

          (e) If the Company or any of its Subsidiaries shall fail to make any
payment of principal of or interest on any Indebtedness of the Company or such

incur a liability to or on account of a Plan under Section 4062, 4063, 4064,

prospects of the Company and its Subsidiaries, taken as a whole; or

then and in each event a Majority in Interest of Outstanding Preferred Stock may
at any time at its or their option, by written notice or notices to the Company,
call a special meeting of stockholders at which the Preferred Stock shall have
the right to elect a majority of the entire Board of Directors of the Company
until such time, if any as all Events of Noncompliance shall have been cured.

     SECTION 15. REMEDIES

          (a) In case any one or more Events of Noncompliance shall occur and be
continuing, the holders of Preferred Stock then Outstanding may proceed to
protect and enforce the rights of such holders by an action at law, suit in
equity or other appropriate proceeding, whether for the specific performance of
any agreement contained herein, or for an injunction against a violation of any
of the terms hereof or thereof, or in aid of the exercise of any power granted
hereby or thereby or by law or for any other remedy (including, without
limitation, damages).

          (b) In case of a default in the observance of any other agreement or
covenant of the Company in any Purchase Document, the Company will pay to the
holder thereof or party thereto such further amount as shall be sufficient to
cover any and all costs and expenses of enforcement and collection, including,
without limitation, reasonable attorneys' fees, expenses and disbursements.  No
course of dealing and no delay on the part of any holder of any Preferred Stock
in exercising any rights or remedies shall operate as a waiver thereof or
otherwise prejudice such holder's rights.  No right or remedy conferred hereby
shall be exclusive of any other right or remedy referred to herein or therein or
available at law, in equity, by statute or otherwise.

          (c) You shall, in addition to other remedies provided by law, have the
right and remedy to have the provisions of this Agreement (including, without
limitation, Sections 6 and 17 hereof) specifically enforced by any court having
equity jurisdiction, it being acknowledged and agreed that any breach or
threatened breach of the provisions of this Agreement (including, without
limitation, Sections 6 and 17 hereof) will cause irreparable injury to you and
that money damages will not provide an adequate remedy.  Nothing contained
herein shall be construed as prohibiting you from pursuing any other remedies
available to you for such breach or threatened breach, including the recovery of
damages from the Company.

          (d) The provisions of this Agreement shall survive the conversion of
all Preferred Stock and Warrants, but the representations and warranties made by
the Company herein shall only survive for three years from the Closing Date.

     SECTION 16. RESTRICTIONS ON TRANSFER

          (a) Each holder of Preferred Stock and each holder of a Warrant by
acceptance thereof agrees that it will not sell or otherwise dispose of any of
the Preferred Stock, Warrants or Conversion Shares issuable upon conversion
thereof unless (i) such Preferred Stock, Warrants or Conversion Shares, as the
case may be,

                                      32
<PAGE>
 
have been registered under the Securities Act, or (ii) such Preferred Stock,
Warrants or Conversion Shares, as the case may be, are sold in accordance with
the applicable requirements and limitations of Rule 144 under the Securities Act
(or any successor rule, regulation or statute to Rule 144), or (iii) the Company
has been furnished with an opinion or opinions reasonably satisfactory to the
Company's counsel to the effect that registration under the Securities Act is
not required for the transfer as proposed (which opinion may be conditioned upon
the transferee's assuming the obligations of a holder of Preferred Stock,
Warrants or Conversion Shares under this Section 16), or (iv) the Company has
been furnished with a letter from the Division of Corporate Finance of the
Commission to the effect that such Division would not recommend any action to
the Commission if such proposed transfer were effected without a registration
statement effective under the Securities Act.  The Company agrees that within 3
Business Days after receipt of any opinion referred to in (iii) above, it will
notify the holder supplying such opinion whether such opinion is satisfactory to
the Company.

          (b) The Company may endorse on all Preferred Stock certificates, on
all Warrants and on all certificates evidencing Conversion Shares a legend
stating or referring to the transfer restrictions contained in paragraph (a)
above; provided that no such legend shall be endorsed on any Preferred Stock
certificates or Warrants or Conversion Share certificates which, when issued,
are no longer subject to the restrictions of this Section 16, and provided,
                                                                  -------- 
further, that if a transfer is made pursuant to clause (i), (ii) or (iv) of
- -------                                                                    
paragraph (a) or if an opinion of counsel provided pursuant to clause (iii) of
paragraph (a) concludes that the legend is no longer necessary, the Company will
deliver upon transfer Preferred Stock Certificates, Warrants or certificates
evidencing Conversion Shares without such legends.

     SECTION 17. REGISTRATION RIGHTS

            17.1.  Registration at the Request of Holders.
                   -------------------------------------- 

                   (a) The Company agrees that from time to time after the
earlier to occur of (i) the first anniversary of the Closing Date and (ii) any
Conversion Date, upon receipt of a Registration Demand satisfying the conditions
under Section 17.1(b) hereof, the Company will (A) promptly (at least 30 days
prior to the filing date) give written notice of the proposed registration to
each holder of Preferred Stock, Warrants or Conversion Shares and (B) with
reasonable promptness, and in any case not later than 75 days after receipt by
the Company of the Registration Demand, file a registration statement with the
Commission relating to all Conversion Shares as to which registration is
requested in the Registration Demand and use its best efforts to make such
registration statement become effective and to qualify the same under the Blue
Sky laws of such states as may be reasonably requested in the Registration
Demand. The Company shall also include under such registration statement any
Conversion Shares requested to be so included by any other holder of Preferred
Stock, Warrants or Conversion Shares by written notice delivered to the Company
within 30 days after the sending of the notice provided for in (A) above, and
may include under such registration statement Shares to be sold directly by the
Company or others; provided, however, that
                   --------  -------      

                                      33
<PAGE>
 
the Company may not include any Shares to be sold directly by the Company or
others to the extent that the underwriter or underwriters of such securities
shall determine in good faith that the inclusion of such Shares would interfere
with the prompt effectiveness of the registration statement or the successful
sale of all Conversion Shares proposed to be sold by the holders of Preferred
Stock, Warrants or Conversion Shares.

          (b) A "Registration Demand" shall be a written notice from one or more
                 -------------------                                            
holders of Preferred Stock, Warrants or Conversion Shares stating that such
holder or holders desire to sell Conversion Shares under circumstances requiring
registration under the Securities Act and requesting that the Company effect
registration with respect to the Conversion Shares held or to be held after
conversion by such holder or holders, provided that such holder or holders
                                      --------                            
giving such notice either (i) hold Preferred Stock, Warrants or Conversion
Shares representing, or entitling the holder thereof to obtain upon conversion,
in the aggregate not less than 25% of the sum of (A) the number of Conversion
Shares then obtainable upon conversion of all Preferred Stock and Warrants then
Outstanding and (B) the number of Conversion Shares then Outstanding from the
previous conversion of Preferred Stock and Warrants or (ii) in the case of a
registration statement on Form S-3 under the Securities Act (or any successor
form), either (A) hold Preferred Stock, Warrants or Conversion Shares
representing, or entitling the holder thereof to obtain upon conversion, in the
aggregate not less than 100,000 Conversion Shares or (B) hold at least 500
shares of Preferred Stock; provided, further, that any such proposed sale of
                           --------  -------                                
Conversion Shares must involve gross offering proceeds (before underwriting fees
and commission) of at least $500,000 in the case of the preceding clause (i) and
at least $250,000 in the case of the preceding clause (ii); provided, further,
                                                            --------  ------- 
that if a holder of Preferred Stock, Warrants or Conversion Shares gives one
Registration Demand under the preceding clause (i), if such Registration Demand
is not withdrawn under Section 17.1(c) hereof and if the Company provides the
registration rights with respect to such Registration Demand which the Company
is required to provide under this Section 17, then such holder may not give a
second Registration Demand under the preceding clause (i) but may participate,
upon the terms of this Section 17, in any registration resulting from one or
more other holders giving a Registration Demand.

          (c) The Company shall be obligated to effect registration and
qualification pursuant to Section 17.1(a) once with respect to a demand under
clause (i) of Section 17.1(b) hereof unless, in the opinion of the lead
underwriter for the offering, all of the Conversion Shares should not be
included in the first registration statement, in which event the Company shall
be obligated to effect a second registration and qualification pursuant to
Section 17.1(a) with respect to the Conversion Shares not included in the first
registration statement, and twice with respect to a demand under clause (ii) of
Section 17.1(b) hereof; provided, however, that the Company shall not be
                        --------  -------                               
obligated to effect registration and qualification more than once in any twelve
month period; and provided, further, that if the holders who have requested a
                  --------  -------                                          
filing of a registration statement under Section 17.1 inform the Company by
written notice that they are withdrawing the request and agree to pay all of the
Company's out-of-pocket expenses (including reasonable legal fees) with respect
to such registration and

                                      34
<PAGE>
 
qualification incurred to the date of the notice under this proviso, then the
registration statement need not be filed and the whole effort will not count as
a registration and qualification to be provided by the Company pursuant to
Section 17.1(a).

            17.2.  Piggyback Rights.  If the Company shall at any time after the
                   ----------------                                         
earlier to occur of (i) the first anniversary of the Closing Date and (ii) any
Conversion Date propose to file a registration statement under the Securities
Act for any underwritten sales of Shares (or any warrants, units, convertibles,
rights or other securities related or linked to any Shares), the Company shall
give written notice of such registration no later than 30 days before its filing
with the Commission to all holders of Preferred Stock, Warrants or Conversion
Shares issued upon conversion thereof. If any such holders of Preferred Stock,
Warrants or Conversion Shares so request within 15 days after the giving of such
notice, the Company shall include in any such registration the Conversion Shares
then held, or to be held after conversion of Preferred Stock and/or Warrants by
such holders, but the Company shall not be obligated to so include the
Conversion Shares to the extent the underwriter or underwriters of such
securities being otherwise registered by the Company shall determine in good
faith that the inclusion of such Conversion Shares would interfere with the
successful sale of such other securities proposed to be sold by such underwriter
or underwriters, in which case such holders of Preferred Stock, Warrants and
Conversion Shares shall be entitled to participate in any such reduced number of
Conversion Shares (if any) which may be included in such registration in
proportion to their relative holdings of Conversion Shares (whether such
Conversion Shares are held directly or through the right to obtain such
Conversion Shares upon the conversion of Preferred Stock or Warrants held
by such holders); provided, however, that in any case other than a primary
                  --------  -------                                       
offering in which no selling stockholders participate, the holders of Preferred
Stock, Warrants or Conversion Shares shall have the right to have at least 25%
of the Conversion Shares then Outstanding or underlying Outstanding Preferred
Stock and Warrants included in the first registration statement which is filed
by the Company after the Closing Date and which meets the requirements of the
first sentence of this Section 17.2; provided, further, that the holders of
                                     --------  -------                     
Preferred Stock, Warrants and Conversion Shares desiring to participate in the
registration shall be entitled to participate in such 25% pro rata in proportion
                                                          --- ----              
to their relative holdings of Conversion Shares (whether such Conversion Shares
are held directly or through the right to obtain such Conversion Shares upon the
conversion of Preferred Stock or Warrants held by such holders).  The
obligations and rights of the Company and the holders under this Section 17.2
shall not affect in any way their obligations and rights under Section 17.1.
Any holder of Preferred Stock, Warrants or Conversion Shares shall, as a
condition to the Company's obligation to include securities held by such holder
in any such registration, agree to execute an underwriting agreement in
customary form as selling shareholders.  Notwithstanding the provisions of
Sections 17.1, in the event that the Company shall file a registration statement
under the Securities Act as described in this Section 17.2, the right of the
holders of Preferred Stock, Warrants or Conversion Shares to give a Registration
Demand shall be suspended until the date 90 days following the effective date of
such registration statement (or until such earlier date as the Company shall
have completed the sale and distribution of all shares to be sold pursuant to
such registration).

            17.3.  Expenses.  Subject to the limitations contained in this 
                   -------- 
Section 17.3 and except as otherwise specifically provided in this Section 17,
the entire costs and expenses of only the first of the registrations and
qualifications demanded pursuant to clause (i) of Section 17.1(b) hereof, all of
the registrations and qualifications demanded pursuant to clause (ii) of Section
17.1(b) hereof and of all registrations and qualifications pursuant to Section
17.2 hereof shall be borne by the Company. A proportionate share (based on the
number of Shares included therein) of all costs and expenses of other
registrations and qualifications demanded pursuant hereto shall be borne by the
selling shareholders making such demands. Such costs and expenses shall include,
without limitation, the reasonable fees and expenses of counsel for the Company
and of its accountants, all other costs, fees and expenses of the Company
incident to the preparation, printing and filing under the Securities Act of the
registration statement and all amendments and supplements thereto, the cost of
furnishing copies of each preliminary prospectus, each final prospectus and each
amendment or supplement thereto to underwriters, dealers and other purchasers of
the Shares and the costs and expenses (including fees and disbursements of
counsel) incurred in connection with the qualification of the Shares under the
Blue Sky laws of various jurisdictions, except that the holders of the Shares
shall bear all selling fees and commissions of any underwriter applicable to
such Shares.

            17.4.  Procedures.
                   ---------- 

                   (a) In the case of each registration or qualification
pursuant to Section 17.1 or 17.2 hereof, the Company will keep all holders of
Preferred Stock, Warrants or Conversion Shares advised in writing as to the
initiation of proceedings for such registration and qualification and as to the
completion thereof, and will advise any such holder, upon request, of the
progress of such proceedings.

                   (b) At its expense, the Company will keep each registration
and qualification under this Section 17 effective (and in compliance with the
Securities Act) by such action as may be necessary or appropriate for a period
of 180 days after the effective date of such registration statement (or until
such earlier date as each holder of Conversion Shares shall have completed the
sale and distribution of all Conversion Shares to be sold pursuant thereto),
including, without limitation, the filing of post-effective amendments and
supplements to any registration statement or prospectus necessary to keep the
registration statement current and the further qualification under any
applicable Blue Sky or other state securities laws to permit such sale or
distribution, all as requested by such holder or holders. The Company will
immediately notify each holder on whose behalf Conversion Shares have been
registered pursuant to this Section 17 at any time when a prospectus relating
thereto is required to be delivered under the Securities Act, of the happening
of an event as a result of which the prospectus included in such registration
statement, as then in effect, includes an untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing and each holder shall refrain from selling any Conversion Shares until
he has received an updated Prospectus from the Company.

                                      36
<PAGE>
 
          (c) The Company will furnish to each holder on whose behalf Conversion
Shares have been registered pursuant to this Section 17 a signed counterpart,
addressed to such holder, of (i) an opinion of counsel for the Company, dated
the effective date of such registration statement, and (ii) a so-called "cold
comfort" letter signed by the independent public accountants who have certified
the Company's financial statements included in such registration statement, and
such opinion of counsel and accountants' letter shall cover substantially the
same matters with respect to such registration statement (and the prospectus
included therein) and, in the case of such accountants' letter, with respect to
events subsequent to the date of such financial statements, as are customarily
covered in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in connection with underwritten public offerings of securities.

          (d) Without limiting any other provision hereof, in connection with
any registration of Shares under this Section 17, the Company will use its best
efforts to comply with the Securities Act, the Securities Exchange Act and all
applicable rules and regulations of the Commission, and will make generally
available to its securities holders, as soon as reasonably practicable, an
earnings statement covering a period of at least twelve months, beginning with
the first month of the first fiscal quarter after the effective date of such
registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) and Rule 158 of the Securities Act.

          (e) In connection with any registration of Conversion Shares under
this Section 17, the Company will provide, if appropriate, a transfer agent and
registrar for the Shares not later than the effective date of such registration
statement.

          (f) In connection with any registration of Conversion Shares under
this Section 17, the Company will, if requested by the underwriters for any
Conversion Shares included in such registration, enter into an underwriting
agreement with such underwriters for such offering, such agreement to contain
such representations and warranties by the Company and such other terms and
provisions as are customarily contained in underwriting agreements with respect
to secondary distributions, including, without limitation, indemnities.

          (g) If the Company at any time proposes to register any of its
securities under the Securities Act, other than pursuant to a request made under
Section 17.1 hereof, whether or not for sale for its own account, and such
securities are to be distributed by or through one or more underwriters, then
the Company will make reasonable efforts, if requested by any holder of
Preferred Stock, Warrants or Conversion Shares who requests registration of
Conversion Shares in connection therewith pursuant to Section 17.2 hereof, to
arrange for such underwriters to include such Conversion Shares among the
securities to be distributed by or through such underwriters.  The holders on
whose behalf Conversion Shares are to be distributed by such underwriters shall
be parties to any such underwriting agreement, and the representations and
warranties by, and the other agreements on the part of, the Company

                                      37
<PAGE>
 
to and for the benefit of such underwriters shall also be made to and for the
benefit of such holders of Conversion Shares.

          (h) Each registration statement, prospectus, amendment, supplement or
any other document filed with respect to a registration under this Section 17
shall be subject to review and, with respect to information concerning the
Purchasers, approval, by the holders registering Shares in such registration and
by their counsel.  Each holder of Preferred Stock, Warrants or Conversion Shares
participating in any registration described in this Section 17 will provide the
Company with such information as may reasonably be requested by the Company in
connection with such registration, and will promptly notify the Company of any
changes in such information required to be disclosed in such registration.

            17.5.  Provision of Documents.  The Company will, at the expense of
                   ----------------------                                   
the Company, furnish to each holder of Preferred Stock, Warrants or Conversion
Shares with respect to which registration has been effected, such number of
registration statements, prospectuses, offering circulars and other documents
incident to any registration or qualification referred to in Sections 17.1 or
17.2 hereof as such holder from time to time may reasonably request.

            17.6.  Indemnification.
                   --------------- 

                   (a) The Company will indemnify and hold harmless each holder
of Conversion Shares and any underwriter (as defined in the Securities Act) for
such holder and each Person, if any, who controls the holder or underwriter
within the meaning of the Securities Act against any losses, claims, damages or
liabilities, joint or several, and expenses (including reasonable attorneys'
fees and expenses and reasonable costs of investigation) to which the holder or
underwriter or such controlling Person may be subject, under the Securities Act
or otherwise, insofar as any thereof arise out of or are based upon any untrue
statement or alleged untrue statement of a material fact contained in any
registration statement under which such Conversion Shares were registered under
the Securities Act pursuant to Sections 17.1 or 17.2 hereof, any prospectus or
preliminary prospectus contained therein, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, except insofar as such losses, claims,
damages, liabilities or expenses arise out of or are based upon any untrue
statement or alleged untrue statement or omission or alleged omission based upon
information furnished to the Company in writing by such holder or by any
underwriter for such holder expressly for use therein.

                   (b) Each Purchaser will indemnify and hold harmless the
Company against any losses, claims, damages or liabilities, joint or several,
and expenses (including reasonable attorneys' fees and expenses and reasonable
costs of investigation) to which the Company may be subject, under the
Securities Act or otherwise, insofar as any thereof (i) arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement

                                      38
<PAGE>
 
under which Conversion Shares were registered under the Securities Act pursuant
to Sections 17.1 or 17.2 hereof, any prospectus or preliminary prospectus
contained therein, or any amendment or supplement thereto, or (ii) arise out of
or are based upon the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, in each case only to the extent that such losses, claims,
damages, liabilities or expenses arise out of or are based upon any untrue
statement or alleged untrue statement or omission or alleged omission based upon
information furnished to the Company in writing by such Purchaser expressly for
use therein.

                  (c) Promptly after receipt by an indemnified party under this
Section 17.6 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 17.6, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under this Section 17.6. In case any such action is brought against any
indemnified party, and it notifies the indemnifying party, the indemnifying
party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party; 
provided, however, that if the defendants in any such action include both the
- --------  ------- 
indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties. After notice from the indemnified party, the indemnifying
party will not be liable to such indemnified party under this Section 17.6 for
any legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless: (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances); or (ii) the indemnifying party has authorized the
employment of counsel for the indemnified party at the expense of the
indemnifying party. After such notice from the indemnifying party to such
indemnified party, the indemnifying party will not be liable for the costs and
expenses of any settlement of such action effected by such indemnified party
without the consent of the indemnifying party, unless such indemnified party
waived its rights under this Section 17.6, in which case the indemnified party
may effect such a settlement without such consent.

            17.7.  Denial of Registration Rights.  The Company shall have the
                   -----------------------------                             
right to deny to any holder of Preferred Stock, Warrants or Conversion Shares
the registration rights granted under this Section 17 if such holder of
Preferred Stock,

                                      39
<PAGE>
 
Warrants or Conversion Shares is at the time able to sell all of the Conversion
Shares sought to be registered without registration or qualification under the
Securities Act or any other applicable securities law over a three month period
pursuant to Rule 144 under the Securities Act. If the Company in good faith
believes that such condition has been satisfied and that the Company is
therefore entitled to deny to a holder the registration rights granted under
this Section 17, then the Company may give notice of such conclusion to such
holder and such registration rights shall thereupon be denied to such holder
unless Moses & Singer LLP or other special counsel for such holder (which other
special counsel shall be reasonably satisfactory to the Company) delivers its
opinion to the Company (within 30 days following such holder's receipt of such
notice of denial from the Company) to the effect that such counsel believes that
the foregoing conditions for denial of the registration rights under this
Section 17 have not been satisfied, in which case all such registration rights
under this Section 17 shall remain available to such holder.

     SECTION 18. CERTAIN FEES AND EXPENSES

          (a) The Company will pay on demand all reasonable costs and expenses
of the Purchasers in connection with the preparation, execution and delivery of,
preservation of rights under and enforcement of this Agreement and the other
Purchase Documents (including, without limitation, the reasonable fees and
expenses of Moses & Singer LLP, special counsel to the Purchasers, and of any
certified public accountants retained by the Purchasers).

          (b) The Company represents and warrants to the Purchasers that there
is no liability for (and the Company will pay and indemnify the Purchaser
against) any fees or expenses (or claims therefor) of any investment banker,
finder or broker employed by the Company in connection with the Purchase
Documents or any of the transactions contemplated thereby, except that the
Company will pay $125,000 and warrants to purchase 100,000 Shares at an exercise
price of $3.125 per Share to Strategic Growth International, Inc. upon the
closing of the sale of 2,496 shares of Preferred Stock to the Purchasers.  The
Purchasers each represent that such Purchaser's have not employed any investment
banker, broker-dealer or finder in connection with the Purchase Documents or any
of the transactions contemplated thereby, and such Purchaser will pay and
indemnify the Company against any fees or expenses (or claims therefore) of any
such Person.

or indirect transferee from any Purchaser, shall be the holder of any Preferred

Exceptions to representations and warranties:

4.1. (a)         The Company is authorized to conduct business in Illinois.
However, the Company is delinquent in the filing of its annual report so it is
not considered to be in good standing at this time.  The Company has completed
the annual report for the State of Illinois and is in the process of filing the
report.  The Company expects to be in good standing in the State of Illinois by
December 11, 1996.  The Company's authorization to conduct business will be
suspended if the annual report is not filed by February 1, 1997.

     The Company has allowed its qualification to conduct business in Virginia
to expire in June 1996 as it has not had an employee in Virginia since August,
1994.  On December 1, 1996, the Company rehired a regional sales manager for the
East Coast region that resides in Virginia.  The Company has not yet determined
whether the hiring of this employee will require the Company to be qualified to
conduct business in the Commonwealth of Virginia and the Company is currently
evaluating those requirements.  The Company expects to determine whether
qualification is required by December 15, 1996 and should it be determined that
it is required, the Company will immediately begin the process for
reinstatement.

4.5 (a)   The Company has contemplated and has conducted internal discussions
regarding the securing of a working capital line-of-credit at some time in the
future.  The Company has not determined that it will seek such a line-of-credit
and there can be no assurance that the Company would be successful in securing
the financing on terms that would be acceptable to the Company should it decide
to seek such financing.

4.5. (c)         The following outstanding warrants contain provisions for
decreasing the exercise price and increasing the number of shares of common
stock issuable upon the exercise of such warrants in the event that the Company
issues common stock below the current Market Price* or securities convertible
into common stock for consideration per share of common stock initially
deliverable upon conversion or exchange of such securities less than Market
Price*:

*    See definition of Market Price in (1) and (2) below.

(1)  The Warrant Agreement defines the "Market Price" as the average of the
     closing prices for the 30 trading days immediately preceding the date that
     the price was set.

(2)  The Warrant Agreements defines the "Market Price" as the average of the
     closing prices for the 10 trading days immediately preceding the date that
     the price was set.

The placement of Series D Preferred Stock may cause the exercise price of the
warrants listed above to decrease and the number of shares issuable upon
exercise of such warrants to increase if the average closing price of the
Company's common stock for the applicable measurement period defined in the
warrant agreements (see (1) and (2) above) is less than the market price of the
common stock on the date the stock purchase agreement for the Series D Preferred
Stock is executed.

To the extent any portion of the purchase price of the Preferred Stock to be
sold to the Purchasers is deemed to constitute payment of the purchase price of
the Warrants to be sold hereunder, notwithstanding the stated value of the
Preferred Stock and the purchase price to be paid for the Warrants pursuant to
the Purchase Agreement, the antidilution provisions of the outstanding warrants
listed above may affect the exercise price and the number of shares issuable
upon exercise of such outstanding warrants.

                                                                         AST 5.1



To Each of the Purchasers Named in the
Purchase Agreement Referred to Below:

Gentlemen:

   We have acted as special counsel to ChatCom, Inc., a California corporation
(the "Company"), in connection with the Purchase Agreement dated as of December
4, 1996 between the Company and each of you (the "Purchase Agreement").  This
opinion is being rendered pursuant to Section 10.5 of the Purchase Agreement.
Terms not otherwise defined herein are used as defined in the Purchase
Agreement.

   In such capacity, we have examined, among other things, executed originals or
copies satisfactory to us of the following "Purchase Documents":

        (i)  the Purchase Agreement;

       (ii)  the certificates evidencing Preferred Stock issued to each of you
             (the "Preferred Stock"); and

      (iii)  the Warrants issued to each of you (the "Warrants").

   In connection with the foregoing, we have also examined originals or copies
satisfactory to us of all such corporate records and other documents and have
made such examinations of law as we have deemed relevant and necessary as a
basis for the opinions hereinafter expressed.  In such examination, we have
assumed the genuineness of all signatures (other than signatures on behalf of
the Company), the authenticity of all documents submitted to us as originals and
the conformity with the original 

<PAGE>
 
documents of all documents submitted to us as copies. As to any facts material
to such opinions, we have, to the extent that such facts were not independently
established by us, relied upon certificates of public officials or certificates
or opinions of officers or other representatives of the Company and other
Persons and the representations and covenants of each Purchaser in the Purchase
Agreement.

   We are opining herein only as to the effect on the subject transaction of the
federal laws of the United States and the internal laws of the State of
California, and we express no opinion with respect to the applicability thereto,
or the effect thereon, of the laws of any other jurisdiction, including without
limitation any matters of municipal law or the laws of any other local agencies
within any state.  In rendering the opinions expressed herein, (i) we have
assumed with your permission that all courts of competent jurisdiction would
enforce such Purchase Documents as written but would apply the internal laws of
the State of California without giving effect to any choice of law provisions
contained therein or any choice of law principles which would result in
application of the internal laws of any other state, and (ii) to the extent that
any questions of legality or legal construction have arisen in connection with
our review, we have applied the laws of the State of California in resolving
such questions.

   Whenever a statement herein is qualified by "to the best of our knowledge" or
a similar phrase, it is intended that those attorneys in this firm who have
rendered legal services in connection with the Purchase Documents do not have
current actual knowledge of the inaccuracy of such statement.  However, except
as otherwise expressly indicated, we have not undertaken any independent
investigation to determine the accuracy of any such statement, and no inference
that we have any knowledge of any matters pertaining to such statement should be
drawn from our representation of the Company.

   Based upon and subject to the foregoing, we are of the opinion that:

        The Company is a corporation duly organized, validly existing and in
good standing under the laws of the State of California and has all requisite
corporate power and authority to own and operate its properties, to carry on its
business as now conducted and to execute, deliver and perform the Purchase
Documents (including, without limitation, the issuance of the Preferred Stock,
the Warrants and the Conversion Shares).  Except for the States of Illinois and
Virginia, as to which we render no opinion, the Company has duly qualified and
is in good standing in each other jurisdiction where the failure to so qualify
would have a material adverse effect on the business, financial condition or
results of operations of the Company on a consolidated basis.
 
        The capital stock of the Company consists of (i) 25,000,000 authorized
shares of Common Stock, of which 9,826,893 shares have been duly authorized and
are validly 

                                      -2-
<PAGE>
 
issued and outstanding and fully paid and non-assessable, and (ii) 1,000,000
shares of Preferred Stock, none of which are outstanding other than the shares
of Preferred Stock being issued to you. Except as disclosed in the Purchase
Agreement including the exhibits thereto, to the best of our knowledge, there
are no outstanding options, warrants, rights, convertible securities or other
agreements under which the Company may become obligated to issue, sell or
transfer shares of its capital stock or other securities, other than the
conversion, redemption and exercise rights granted under the Purchase Agreement
with respect to the Preferred Stock and the Warrants.
 
        The execution, delivery and performance by the Company of the Purchase
Documents (including, without limitation, the issuance of the Preferred Stock,
the Warrants and the Conversion Shares as contemplated by the Purchase
Agreement) have been duly authorized by all required corporate and other
actions.  The Purchase Documents have been duly executed and delivered by the
Company and constitute the legal, valid and binding obligations of the Company
enforceable against the Company in accordance with their respective terms,
subject to (i) any applicable bankruptcy, reorganization, insolvency, moratorium
or other similar laws affecting the enforcement of creditors' rights generally,
(ii) the effect of the limitations imposed by California or federal law or
equitable principles upon the availability of specific performance, injunctive
relief or other equitable remedies, (iii) the effect of California law, which
provides that a court may refuse to enforce or may limit the application of, a
contract or any clause thereof which the court finds as a matter of law to have
been unconscionable at the time it was made or contrary to public policy, (iv)
the unenforceability of any forum selection clause by a federal court, and (v)
the availability of other equitable remedies.  The foregoing opinion does not
cover any portion of the voting shift provisions of subparagraph 3(b) of the
Certificate of Determination and Decrease pursuant to which the Preferred Stock
is authorized, except upon an event of noncompliance described in subparagraph
3(b)(i) thereof. However, nothing has come to our attention in our review of
California law that deals directly with voting shift provisions such as those
contained in clauses (ii) through (ix) of subparagraph 3(b) of said Certificate
of Determination and Decrease or that would cause us to conclude that the voting
shift provisions would not be a binding obligation of the Company or would be
unenforceable in accordance with their terms upon any event of noncompliance
described in said clauses (ii) through (ix).

                                      -3-

        To the best of our knowledge, there is no action, suit, proceeding,
investigation or claim pending or threatened in law, equity or otherwise before
any court, administrative agency or arbitrator which either (i) questions the
validity of any of the Purchase Documents or any action taken or to be taken
pursuant thereto, or (ii) might adversely affect the right, title or interest of
the Purchasers to the Preferred Stock, the Warrants or the Conversion Shares or
(iii) might result in a material adverse change in the assets, properties,
liabilities, business, results of operations or financial or other condition of
the Company.  To the best of our knowledge, there are no adverse orders,
judgments, writs, injunctions, decrees or demands of any court or administrative
body, domestic or foreign, or of any other governmental agency or
instrumentality, domestic or foreign, outstanding against the Company.
 
        Neither the execution, delivery nor performance by the Company of any of
the Purchase Documents or any of the transactions contemplated thereby
(including, without limitation, the issuance of the Preferred Stock, the
Warrants and the Conversion Shares as contemplated by the Purchase Agreement)
(i) violates or conflicts or will violate or conflict with, with or without the
giving of notice or the passage of time or both, any provision of (A) the
Articles of Incorporation or By-Laws, both as amended, of the Company or (B) any
law, rule, regulation, or, to the best of our knowledge, any order, judgment,
writ, injunction, decree, material agreement, material indenture or other
material instrument applicable to the Company or any of its properties (or to
which the Company is a party or by which it or its properties may be bound),
(ii) to the best of our knowledge, results or will result in the creation of any
security interest or lien upon any of the Company's properties, assets or
revenues, (iii) to the best of our knowledge, requires or will require the
consent, waiver, approval, order or authorization of, or declaration,
registration, qualification or filing with, any Person (whether or not a
governmental authority and including, without limitation, any stockholder
approval), or (iv) to the best of our knowledge, causes or will cause anti-
dilution clauses of any outstanding securities to become operative, except as
disclosed in the exhibits to the Purchase Agreement.  To the best of our
knowledge, no such provision does or will materially adversely affect the
assets, properties, liabilities, business, results of operations or financial or
other condition of the Company or the ability of the Company to perform the
Purchase Documents or the transactions contemplated thereby.

                                      -4-
<PAGE>
 
        To the best our knowledge, all taxes, duties, imposts or other
governmental charges, if any, payable in connection with the execution, delivery
and performance by the Company of each of the Purchase Documents, and the
continued validity of each of said instruments, have been duly paid.
 
        The Shares of Common Stock reserved for issuance in accordance with the
Purchase Agreement have been validly authorized and reserved for such purpose,
and upon issuance thereof upon conversion of the Preferred Stock or the exercise
of Warrants, as the case may be, as provided in the Purchase Agreement, will be
validly issued, fully paid and non-assessable, and the issuance of such Shares
will not be subject to any presently existing pre-emptive or, to the best of our
knowledge, similar rights.
 
        The offer, sale, purchase, issue and delivery of the Preferred Stock,
the Warrants and the Conversion Shares pursuant to the Purchase Agreement
constitute exempted transactions under the Securities Act of 1933, as amended.
The registration of the Preferred Stock, the Warrants and the Conversion Shares
under such Act is not required in connection with any such offer, sale,
purchase, issue or delivery of the Preferred Stock, the Warrants or the
Conversion Shares.
 
        The Company is not a "public utility company" or a "holding company," or
a "subsidiary company" of a "holding company" or an "affiliate" of a "holding
company" or an "affiliate" of such a "subsidiary company," as such terms are
defined in the Public Utility Holding Company Act of 1935, as amended, or an
"investment company," or a company "controlled" by an "investment company,"
within the meaning of the Investment Company Act of 1940, as amended.
 
        The offer, sale, purchase, issue and delivery of the Preferred Stock and
the Warrants pursuant to the Purchase Agreement does not violate Regulations G,
T, U or X of the Board of Governors of the Federal Reserve System.

   This opinion is rendered only to you and is solely for your benefit in
connection with the transactions covered hereby.  This opinion may not be relied
upon by you for any other purpose, or quoted to or relied upon by any other
person, firm, corporation or entity for any purpose, without our prior written
consent.

                            Very truly yours,

                                      -5-

    Void after 5:00 p.m. Pacific Standard Time, on December 13, 2001 
Warrant to Purchase One Hundred Thousand (100,000) Shares of Common Stock

                       WARRANT TO PURCHASE COMMON STOCK

                                      OF

                                 CHATCOM, INC.
                           a California corporation

    This is to certify that, for value received, Strategic Growth International,
Inc. ("Holder"), is entitled to purchase, subject to the provisions of this
Warrant, from ChatCom, Inc., a California corporation ("Company"), one hundred
thousand (100,000) fully paid, validly issued and nonassessable shares of common
stock, no par value, of the Company ("Common Stock"), at a price of $3.125 per
share at any time or from time to time during the period from May1, 1997, to
December 13, 2001.

    The number of shares of Common Stock to be received upon the exercise of
this Warrant and the price to be paid for each share of Common Stock may be
adjusted from time to time as hereinafter set forth. The shares of Common Stock
deliverable upon such exercise, and as adjusted from time to time, are
hereinafter sometimes referred to as "Warrant Shares" and the exercise price of
a share of Common Stock in effect at any time and as adjusted from time to time
is hereinafter sometimes referred to as the "Exercise Price".

    1.  Exercise of Warrant. This Warrant may be exercised in whole or in part
        -------------------
at any time from time to time on or after May 1, 1997, and until December 13,
2001; provided however, that if either such day is a day on which banking
institutions in the State of California are authorized by law to close, then on
the next succeeding day which shall not be such a day. This Warrant may be
exercised by presentation and surrender hereof to the Company at its principal
office, with the Purchase Form annexed hereto duly executed, with signature
guaranteed, and accompanied by payment of the Exercise Price for the number of
Warrant Shares specified in such form. As soon as practicable after each
exercise of the Warrants, but not later than twenty (20) days from the date of
such exercise, the Company shall issue and deliver to the Holder a certificate
or certificates for the Warrant Shares issuable upon such exercise, registered
in the name of the Holder or its designee.

    If this Warrant should be exercised in part only, the Company shall, upon
surrender of this Warrant for cancellation, execute and deliver a new Warrant
evidencing the rights of the Holder hereof to purchase the balance of the
Warrant Shares purchasable hereunder. Upon receipt by the Company of this
Warrant at its office, in proper form for exercise, the Holder shall be deemed
to be the holder of 
<PAGE>
 
                                 CHATCOM, INC.


record of the shares of Common Stock issuable upon such exercise,
notwithstanding that the stock transfer books of the Company shall then be
closed or that certificates representing such shares of Common Stock shall not
then by physically delivered to the Holder.

    2.  Reservation of Shares.  The Company shall at all time reserve for
        --------------------- 
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants.

    3.  Fractional Shares.  No fractional shares or script representing
        -----------------
fractional shares shall be issued upon the exercise of this Warrant. With
respect to any fraction of a share called for upon any exercise hereof, the
Company shall pay to the Holder an amount in cash equal to such fraction
multiplied by the current market value of a share, determined as follows:

        3.1.  If the Common Stock is listed on a National Securities Exchange or
admitted to unlisted trading privileges on such exchange or listed for trading
on the NASDAQ system, the current market value shall be the last reported sale
price of the Common Stock on such exchange or system on the last business day
prior to the date of exercise of the Warrant or if no such sale is made on such
day, the average closing bid and asked prices for such day on such exchange or
system; or

        3.2.  If the Common Stock is not so listed or admitted to unlisted
trading privileges, the current market value shall be the mean of the last
reported bid and asked prices reported by the National Quotation Bureau, Inc.,
on the last business day prior to the date of the exercise of this Warrant; or

        3.3.  If the Common Stock is not so listed or admitted to unlisted
trading privileges and did and asked prices are not so reported, the currant
market value shall be an amount, not less than book value thereof as at the end
of the most recent fiscal year of the Company ending prior to the date of the
exercise of the Warrant, determined in such reasonable manner as may be
prescribed by the Board of Directors of the Company.

    4.  Loss of Warrant. Upon receipt by the Company of evidence satisfactory to
        ---------------
it of the loss, theft, destruction or mutilation of this Warrant, and (in the
case of loss, theft or destruction) of reasonably satisfactory indemnification,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.

    5.  Rights of the Holder.  The Holder shall not, by virtue hereof, be
        --------------------
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.

    6.  Anti-Dilution Provisions.  The Exercise Price in effect at any time and
        ------------------------
the number and kind of securities purchasable upon the exercise of the Warrants
shall be subject to adjustment from time to time upon the happening of certain
events, as follows:

        6.1.  In case the Company shall (i) declare a dividend or make a
distribution on its outstanding shares of Common Stock in shares of Common
Stock; (ii) subdivide or reclassify its outstanding shares of Common Stock into
a greater number of shares; or (iii) combine or reclassify its outstanding
shares of Common Stock into a smaller number of shares, the Exercise Price in
effect at the time of the record date for such dividend or distribution or of
the effective date of such subdivision, combination or reclassification shall be
proportionately adjusted so that the Holder of this Warrant exercised after such
date shall be entitled to receive the aggregate number and kind of shares which,
if this Warrant had been exercised by such Holder immediately prior to such
date, he would have owned upon such exercise and been entitled to receive upon
such dividend, subdivision, combination or reclassification.

        6.2.  In case the Company shall hereafter distribute to the holders of
its Common Stock evidences of its indebtedness or assets (excluding cash
dividends or distributions and dividends or distributions referred to in
Subsection 6.1 above) or subscription rights or warrants, then in each such case
the Exercise Price in effect thereafter shall be determined by multiplying the
Exercise Price in effect immediately prior thereto by a fraction, the numerator
of which shall be the total number of shares of Common Stock outstanding
multiplied by the current market price per share of Common Stock (as defined in
Subsection 6.7 below), less the fair market value (as determined by the
Company's Board of Directors) of said assets or evidences of indebtedness so
distributed or of such rights or warrants, and the denominator of which shall be
the total number of shares of Common Stock outstanding multiplied by such
current market price per share of Common Stock. Such adjustment shall be made
whenever any such distribution is made and shall become effective immediately
after the record date for the determination of shareholders entitled to receive
such distribution.

        6.3  Whenever the Exercise Price payable upon exercise of each Warrant
is adjusted pursuant to Subsections 6.1 and 6.2 above, the number of shares
purchasable upon exercise of this Warrant shall simultaneously be adjusted by
multiplying the number of shares initially issuable upon exercise of this
Warrant by the Exercise Price in effect on the date hereof and dividing the
product so obtained by the Exercise Price, as adjusted.

        6.4. For the purposes of any computation under Subsection 6.2 above, the
current market price per share of Common Stock at any date shall be deemed to be
the average of the daily closing prices for ten (10) consecutive business days
before 
<PAGE>
 
                                 CHATCOM, INC.


such date. The closing price for each day shall be the last sale price regular
way or, in case no such reported sale takes place on such day, the average of
the last reported bid and asked prices regular way, in either case on the
principal national securities exchange on which the Common Stock is admitted to
trading or listed, or if not listed or admitted to trading on such exchange, the
average of the highest reported bid and lowest reported asked prices as reported
by NASDAQ, or other similar organization, if NASDAQ is no longer reporting such
information, or if not so available, the fair market price as determined by the
Board of Directors.

        6.8  No adjustment in the Exercise Price shall be required unless such
adjustment would require an increase or decrease of at least five cents ($0.05)
in such price. All calculations under this Section 6 shall be made to the
nearest cent or to the nearest one-hundredth of a share, as the case may be.

    7.  Reclassification, Reorganization or Merger.  In case of any
        ------------------------------------------
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation, or in case of any sale, lease or
conveyance to another corporation of the property of the Company as an entirety,
the Company shall, as a condition precedent to such transaction, cause effective
provisions to be made so that the Holder shall have the right thereafter by
exercising this Warrant at anytime prior to the expiration of the Warrant, to
purchase the kind and amount of shares of stock and other securities and
property receivable upon such reclassification, capital reorganization and other
change, consolidation, merger, sale or conveyance by a holder of the number of
shares of Common Stock which might have been purchased upon the exercise of this
Warrant, immediately prior to such reclassification, change, consolidation,
merger, sale or conveyance.

    1.  Purpose; Effectiveness of the Plan
        ----------------------------------

        1.1  The purpose of the Plan is to advance the interests of the Company
and its stockholders by helping the Company obtain and retain the service of
employees, officers, consultants, and directors, upon whose judgment, initiative
and efforts the Company is substantially dependent, and to provide those persons
with further incentives to advance the interests of the Company.

        1.2  The Plan will become effective on the date of its adoption by the
Board, provided the Plan is approved by the stockholders of the Company
(excluding holders of shares of Stock issued by the Company pursuant to the
exercise of options granted under this Plan) within twelve (12) months before or
after that date. If the Plan is not so approved by the stockholders of the
Company, any options granted under this Plan will be rescinded and will be void.
This Plan will remain in effect until it is terminated by the Board (or the
Committee, as defined hereafter), under Section 9 hereof, or September 1, 2004,
whichever is earlier. This Plan will be governed by, and construed in accordance
with, the laws of the State of California.

    2.  Certain Definitions
        -------------------

determined by the Committee, consistent with the requirements of Section 422 of
the Code and to the extent consistent therewith, as follows:

    question, then the Fair Market Value will be equal to the closing price
    reported by the applicable composite-transactions report for such date;

    Value will be equal to the last-transaction price quoted by the NASDAQ
    system for such date;

             (c) If the Stock was traded over-the-counter on the date in

    Market Value will be equal to the average of the last reported

Eligible Participants as of the time of such grant. Subject to the provisions of
Section 4.4, 5 and 6 hereof, there is no limitation on the number of Options
that may be granted to an Eligible Participant.

    4.  Administration
        --------------

        4.1  Committee.  The Committee, if appointed by the Board, will
             --------- 
administer this Plan. If the Board, in its discretion, does not appoint such a
Committee, the Board itself will administer this Plan and take such other
actions as the Committee is authorized to take hereunder; provided that the
Board may take such actions hereunder in the same manner as the Board may take
other actions under the Company's Articles of Incorporation and Bylaws
generally.

        4.2  Authority and Discretion of Committee.  The Committee will have
             -------------------------------------
full and final authority in its discretion, at any time and from time to time,
subject 
<PAGE>
 
                                 CHATCOM, INC.


only to the express terms, conditions and other provisions of the Company's
Articles of Incorporation, Bylaws and this Plan, and the specific limitations on
such discretion set forth herein:

             (a)  to select and approve the persons who will be granted Options
    under this Plan from among the Eligible Participants, and to grant to any
    person so selected one or more Options to purchase such number of shares of
    Option Stock as the Committee may determine;

             (b)  to determine the period or periods of time during which
    Options may be exercised, the Option Price and the duration of such Options
    and other matters to be determined by the Committee in connection with
    specific Option grants and Option Agreements as specified under this Plan;

             (c)  to interpret this Plan, to prescribe, amend and rescind rules
    and regulations relating to this Plan, and to make all other determinations
    necessary or advisable for the operation and administration of this Plan;
    and

             (d)  to delegate all or a portion of its authority under
    subsections (a) and (b) of this Section 4.2 to one or more directors of the
    Company who are executive officers of the Company, but only in connection
    with Options granted to Eligible Participants who are not subject to the
    reporting and liability provisions of Section 16 of the Securities Exchange
    Act of 1934, as amended (the "Exchange Act"), and the rules and regulations
    thereunder, and subject to such restrictions and limitations (such as the
    aggregate number of shares of Option Stock called for by such Options that
    may be granted) as the Committee may decide to impose on such delegate
    directors.

        4.3  [Reserved]
              --------

        4.4  Designation of Options.  Except as otherwise provided herein, the
             ----------------------
Committee will designate any Option granted hereunder either as an ISO or as an
NSO. To the extent that the Fair Market Value (determined at the time the Option
is granted)of Stock with respect to which all ISOs are exercisable for the first
time by any individual during any calendar year (pursuant to this Plan and all
other plans of the Company and/or its subsidiaries) exceeds $100,000, such
option will be treated as an NSO. Notwithstanding the general eligibility
provisions of Section 3 hereof, the Committee may grant ISOs only to persons who
are employees of the Company and/or its subsidiaries.

        4.5  Option Agreements.  Options will be deemed granted hereunder only
             -----------------
upon the execution and delivery of an Option Agreement by the Optionee and a
duly authorized officer of the Company. Options will not be deemed granted
hereunder merely upon the authorization of such grant by the Committee.

                                 CHATCOM, INC.

        5.  Shares Reserved for Options
            ---------------------------

            5.1  Option Pool.  The aggregate number of shares of Option Stock
                 -----------
that may be issued pursuant to the exercise of Options granted under this Plan
will not exceed two million (2,000,000) (the "Option Pool"), provided that such
number will be increased by the number of shares of Option Stock that the
Company subsequently may reacquire through repurchase or otherwise. Shares of
Option Stock that would have been issuable pursuant to Options, but that are no
longer issuable because all or part of those Options have terminated or expired,
will be deemed not to have been issued for purposes of computing the number of
shares of Option Stock remaining in the Option Pool and available for issuance.

            5.2  Adjustments Upon Changes in Stock.  In the event of any change
                 ---------------------------------
in the outstanding Stock of the Company as a result of a stock split, reverse
stock split, stock dividend, recapitalization, combination, or reclassification,
appropriate proportionate adjustments will be made in: (i) the aggregate number
of shares of Option Stock in the Option Pool that may be issued pursuant to the
exercise of Options granted hereunder; (ii) the Option Price and the number of
shares of Option Stock called for in each outstanding Option granted hereunder;
and (iii) other rights and matters determined on a per share basis under this
Plan or any Option Agreement hereunder. Any such adjustments will be made only
by the Board, and when so made will be effective, conclusive and binding for all
purposes with respect to this Plan and all Options then outstanding. No such
adjustments will be required by reason of the issuance or sale by the Company
for cash or other consideration of additional shares of its Stock or securities
convertible into or exchangeable for shares of its Stock.

        6.  Terms of Stock Option Agreements
            --------------------------------

            Each Option granted pursuant to this Plan will be evidenced by an
agreement (an "Option Agreement") between the Company and the person to whom
such Option is granted, in form and substance satisfactory to the Committee in
its sole discretion, consistent with this Plan. Without limiting the foregoing,
each Option Agreement (unless otherwise stated therein) will be deemed to
include the following terms and conditions:

            6.1  Covenants of Optionee.  At the discretion of the Committee, the
                 ---------------------
person to whom an Option is granted hereunder, as a condition to the granting of
the Option, must execute and deliver to the Company a confidential information
agreement approved by the Committee. Nothing contained in this Plan, any Option
Agreement, or in any other agreement executed in connection with the granting of
an Option under this Plan will confer upon any Optionee any right with respect
to the continuation of his or her status as an employee of, consultant or
independent contractor to, or director of, the Company or its subsidiaries.
<PAGE>
 
                                 CHATCOM, INC.


            6.2  Vesting Periods.  Except as otherwise provided herein, each
                 --------------- 
Option Agreement may specify the period or periods of time within which each
Option or portion thereof will first become exercisable (the "Vesting Period")
with respect to the total number of shares of Option Stock called for thereunder
(the "Total Award Option Stock"). Such Vesting Periods will be fixed by the
Committee in its discretion, and may be accelerated or shortened by the
Committee in its discretion.

            6.3  Exercise of the Option.
                 ----------------------

                 (a)  Mechanics and Notice. An Option may be exercised to the
                      --------------------
    extent exercisable:

                      (1)  by giving written notice of exercise to the Company,
    specifying the number of full shares of Option Stock to be purchased and
    accompanied by full payment of the Option Price thereof and the amount of
    withholding taxes pursuant to subsection 6.3(b) below; and
 
                      (2)  by giving assurances satisfactory to the Company that
    the shares of Option Stock to be purchased upon such exercise are being
    purchased for investment and not with a view to resale in connection with
    any distribution of such shares in violation of the 1933 Act; provided,
    however, that in the event the Option Stock called for under the Option is
    registered under the 1933 Act, or in the event resale of such Option stock
    without such registration would otherwise be permissible, this second
    condition will be inoperative if, in the opinion of counsel for the Company,
    such condition is not required under the 1933 Act, or any other applicable
    law, regulation or rule of any governmental agency.

                 (b)  Withholding Taxes.  As a condition to the issuance of the
                      -----------------
    shares of Option Stock upon full or partial exercise of an NSO granted under
    this Plan, the Optionee will pay to the Company in cash, or in such other
    form as the Committee may determine in its discretion, the amount of the
    Company's tax withholding liability required in connection with such
    exercise. For purposes of this subsection 6.3(b), "tax withholding
    liability" will mean all federal and state income taxes, social security
    tax, and any other taxes applicable to the compensation income arising from
    the transaction required by applicable law to be withheld by the Company.

            6.4  Payment of Option Price.  Each Option Agreement will specify
                 -----------------------
the Option Price with respect to the exercise of Option Stock thereunder, to be
fixed by the Committee in its discretion, but in no event will the Option Price
for an ISO granted hereunder be less than the Fair Market Value (or, in case the
Optionee is a 10% Stockholder, one hundred ten percent (110%) of such Fair
Market Value) of the Option Stock at the time such ISO is granted, and in no
event will the Option Price for 
<PAGE>
 
                                 CHATCOM, INC.


an NSO granted hereunder be less than 75% of Fair Market Value of the Option
Stock at the time such NSO is granted. The Option Price will be payable to the
Company in United States dollars in cash or by check, or such other legal
consideration as may be approved by the Committee, in its discretion.

                 (a)  For example, the Committee, in its discretion, may permit
    a particular Optionee to pay all or a portion of the Option Price, and/or
    the tax withholding liability set forth in subsection 6.3(b) above, with
    respect to the exercise of an Option either by surrendering shares of Stock
    already owned by such Optionee or by withholding shares of Option Stock,
    provided that the Committee determines that the Fair Market Value of such
    surrendered Stock or withheld Option Stock is equal to the corresponding
    portion of such Option Price and/or tax withholding liability, as the case
    may be, to be paid for therewith.

                 (b)  If the Committee permits an Optionee to pay any portion of
    the Option Price and/or tax withholding liability with shares of Stock with
    respect to the exercise of an Option (the "Underlying Option") as provided
    in subsection 6.4(a) above, then the Committee, in its discretion, may grant
    to such Optionee (but only if Optionee remains an Eligible Participant at
    that time) additional NSOs, the number of shares of Option Stock called for
    thereunder to be equal to all or a portion of the Stock so surrendered or
    withheld (a "Replacement Option"). Each Replacement Option will be evidenced
    by an Option Agreement. Unless otherwise set forth therein, each Replacement
    Option will be immediately exercisable upon such grant (without any Vesting
    Period) and will be coterminous with the Underlying Option. The Committee,
    in its sole discretion, may establish such other terms and conditions for
    Replacement Options as it deems appropriate.

            6.5  Termination of the Option.
                 -------------------------

                 (a)  Early Termination.  Except as otherwise provided herein,
                      -----------------
    each Option Agreement will specify the period of time, to be fixed by the
    Committee in its discretion, during which the Option granted therein will be
    exercisable, not to exceed ten (10) years from the date of grant in the case
    of an ISO (the "Option Period"); provided that the Option Period will not
    exceed five (5) years from the date of grant in the case of an ISO granted
    to a 10% Stockholder. To the extent not previously exercised, each Option
    will terminate upon the expiration of the Option Period specified in the
    Option Agreement; provided, however, that each such Option will terminate,
    if earlier: (i) ninety (90) days after the date that the Optionee ceases to
    be an Eligible Participant for any reason, other than by reason of death or
    disability or a Just Cause Termination; (ii) twelve (12) months after the
    date that the Optionee ceases to be an Eligible Participant by reason of
    such person's death or disability; or (iii) immediately as of the date that
    the Optionee ceases to be an Eligible Participant by reason of a Just Cause
    Termination.

                 (b)  Corporate Transactions.  In the event of a sale of all or
                      ----------------------
    substantially all of the assets of the Company, or a merger or consolidation
    or other reorganization in which the Company is not the surviving
    corporation, or in which the Company becomes a subsidiary of another
    corporation, or a reverse merger in which the Company is the surviving
    corporation but the shares of stock outstanding immediately preceding the
    merger are converted by virtue of the merger into other property (any of the
    foregoing events, a "Corporate Transaction"), then notwithstanding anything
    else herein, and unless the Board, in its sole discretion, determines
    otherwise, the successor corporation must agree to assume the outstanding
    Options or substitute therefor comparable options of such successor
    corporation, or a parent or subsidiary of such successor corporation. If for
    whatever reason the successor corporation does not assume the outstanding
    Options or substitute therefor comparable options of such successor
    corporation, or a parent or subsidiary of such successor corporation, then
    in that event, the Board or the Committee shall notify each Optionee not
    less than thirty (30) days prior thereto of the pendency of a Corporate
    Transaction. Upon delivery of such notice, any Option outstanding shall be
    exercisable in full and not only as to those shares with respect to
    installments, if any, have been accrued; subject, however, to earlier
    expiration or termination as provided elsewhere in this Plan.

            6.6  Options Nontransferable.  No Option will be transferable by the
                 -----------------------
Optionee otherwise than by will or the laws of descent and distribution, or in
the case of an NSO, pursuant to a QDRO. During the lifetime of the Optionee, the
Option will be exercisable only by him or her, or the transferee of an NSO if it
was transferred pursuant to a QDRO.

            6.7  Qualification of Stock.  The right to exercise an Option will
                 ----------------------
be further subject to the requirement that if at any time the Board determines,
in its discretion, that the listing, registration or qualification of the shares
of Option Stock called for thereunder upon any securities exchange or under any
state or federal law, or the consent or approval of any governmental regulatory
authority, is necessary or desirable as a condition of or in connection with the
granting of such Option or the purchase of shares of Option Stock thereunder,
the Option may not be exercised, in whole or in part, unless and until such
listing, registration, qualification, consent or approval is effected or
obtained free of any conditions not acceptable to the Board, in its discretion.

            6.8  Additional Restrictions on Transfer.  By accepting Options
                 -----------------------------------
and/or Option Stock under this Plan, the Optionee will be deemed to represent,
warrant and agree as follows:

                 (a)  Securities Act of 1933.  The Optionee understands that the
                      ----------------------
    shares of Option Stock have not been registered under the 1933 Act, and that
    such shares are not freely tradeable and must be held indefinitely unless
    such shares 
<PAGE>
 
                                 CHATCOM, INC.


    are either registered under the 1933 Act or an exemption from such
    registration is available. The Optionee understands that the Company is
    under no obligation to register the shares of Option Stock.

                 (b)  Other Applicable Laws.  The Optionee further understands
                      ---------------------
    that Transfer of the Option Sock requires full compliance with the
    provisions of all applicable laws.

                 (c)  Investment Intent.  Unless a registration statement is in
                      -----------------
    effect with respect to the sale of Option Stock obtained through exercise of
    Options granted hereunder. Upon exercise of any Option: (1) the Optionee
    will purchase the Option Stock for his or her own account and not with a
    view to distribution within the meaning of the 1933 Act, other than as may
    be effected in compliance with the 1933 Act and the rules and regulations
    promulgated thereunder; (2) no one else will have any beneficial interest in
    the Option Stock; and (3) he or she has no present intention of disposing of
    the Option Stock at any particular time.

            6.9  Compliance with Laws.  Notwithstanding any other provision of
                 --------------------
this Plan, Options may be granted pursuant to this Plan, and Option Stock may be
issued pursuant to the exercise thereof by an Optionee, only after there has
been compliance with all applicable federal and state laws, and all of the same
will be subject this overriding condition. The Company will not be required to
register or qualify Option Stock with the Securities and Exchange Commission or
any State agency, except that the Company will register with, or as required by
local law, file for and secure an exemption from such registration requirements
from, the applicable securities administrator and other officials of each
jurisdiction in which an Eligible Participant would be granted an Option
hereunder prior to such grant.

            6.10  Stock Certificates.  Certificates representing the Option
                  ------------------
Stock issued pursuant to the exercise of Options will bear all legends required
by law and necessary to effectuate this Plan's provisions. The Company may place
a "stop transfer" order against shares of the Option Stock until all
restrictions and conditions set forth in this Plan and in the legends referred
to in this Section 6.10 have been complied with.

            6.11  Notices.  Any notice to be given to the Company under the
                  -------
terms of an Option Agreement will be addressed to the Company at its principal
executive office, Attention: Corporate Secretary, or at such other address as
the Company may designate in writing. Any notice to be given to an Optionee will
be addressed to the Optionee at the address provided to the Company by the
Optionee. Any such notice will be deemed to have been duly given if and when
enclosed in a properly sealed envelope, addressed as aforesaid, registered and
deposited, postage and registry fee prepaid, in a post office or branch post
office regularly maintained by the United States Government.

                                 CHATCOM, INC.


            6.12  Other Provisions.  The Option Agreement may contain such other
                  ----------------
terms, provisions and conditions, including such special forfeiture conditions,
rights of repurchase, rights of first refusal and other restrictions on Transfer
of Option Stock issued upon exercise of any Options granted hereunder, not
inconsistent with this Plan, as may be determined by the Committee in its sole
discretion.

            6.13 [Reserved]
                  --------


    7.  Proceeds From Sale of Stock
        ---------------------------

    Cash proceeds from the sale of shares of Option Stock issued from time to
time upon the exercise of Options granted pursuant to this Plan will be added to
the general funds of the Company and as such will be used from time to time for
general corporate purposes.

    8.  Modification, Extension and Renewal of Options
        ----------------------------------------------

    Subject to the terms and conditions and within the limitations of this Plan,
the Committee may modify, extend or renew outstanding Options granted under this
Plan, or accept the surrender of outstanding Options (to the extent not
theretofore exercised) and authorize the granting of new Options in substitution
therefor (to the extent not theretofore exercised). Notwithstanding the
foregoing, however, no modification of any Option will, without the consent of
the holder of the Option, alter or impair any rights or obligations under any
Option theretofore granted under this Plan.

    9.  Amendment and Discontinuance
        ----------------------------

    The Board may amend, suspend or discontinue this Plan at any time or from
time to time; provided that no action of the Board will cause ISOs granted under
this Plan not to comply with Section 422 of the Code unless the Board
specifically declares such action to be made for that purpose. Moreover, no such
action may alter or impair any Option previously granted under this Plan without
the consent of the holder of such Option.

    10.  Plan Compliance with Rule 16b-3
         -------------------------------

    With respect to persons subject to Section 16 of the Exchange Act,
transactions under this Plan are intended to comply with all applicable
conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent
any provision of the Plan or action by the Plan Administrators fails so to
comply, it shall be deemed null and void, to the extent permitted by law and
deemed advisable by the Plan Administrators.
