                                PROXY STATEMENT

           Annual Meeting of Shareholders to be held on July 27, 2000

   This proxy statement ("Proxy Statement") is being furnished to the holders
of common stock, par value $0.001 per share, of Pac-West Telecomm, Inc. ("Pac-
West" or the "Company") in connection with the solicitation of proxies by and
on behalf of our board of directors for use at the annual meeting of
shareholders (the "Annual Meeting") to be held on July 27, 2000 at 10:00 a.m.,
Mountain time, and at any adjournments or postponements thereof. The purpose of
the Annual Meeting is to elect three directors to our board of directors,
approve the amendment and restatement of our Amended and Restated Articles of
Incorporation, approve the amendment and restatement of our 1999 Stock
Incentive Plan, approve the adoption of the 2000 Employee Stock Purchase Plan
and to ratify the appointment of Arthur Andersen LLP as our independent public
accountants for the 2000 fiscal year. Each of these proposals are described
more fully in this Proxy Statement.

   This Proxy Statement, Proxy Form and our 1999 Annual Report, which includes
our Annual Report on Form 10-K for the Fiscal Year ended December 31, 1999, are
being mailed on or about June 26, 2000 to holders of record of the our common
stock at the close of business on June 15, 2000.

   If the enclosed Proxy Form is properly signed, dated and returned to Pac-
West, the individuals identified as proxies thereon will vote the shares
represented by the Proxy Form in accordance with the directions noted thereon.
If no direction is indicated, the proxies will vote FOR the nominees named
herein as directors, FOR the amendment and restatement of our Amended and
Restated Articles of Incorporation, FOR the amendment and restatement of our
1999 Stock Incentive Plan, FOR the adoption of the 2000 Employee Stock Purchase
Plan and FOR the ratification of the appointment of Arthur Andersen LLP as our
independent public accountants for the 2000 fiscal year. At this time, our
management is not aware of any matters other than those discussed in this Proxy
Statement that will be presented at the Annual Meeting. If other matters are
presented, all proxies will be voted in accordance with the recommendations of
our management.

   Returning your completed Proxy Form will not prevent you from voting in
person at the Annual Meeting if you are present and wish to vote. In addition,
you may revoke your proxy any time before it is voted by written notice to our
Corporate Secretary prior to the Annual Meeting at our principal executive
offices at the address above or by submission of a later-dated proxy.

   Each outstanding share of common stock entitles the holder thereof to one
vote on each matter to come before the Annual Meeting. As of April 30, 2000,
there were 35,861,519 shares of our common stock outstanding. The presence in
person or by proxy of a majority of the shares of common stock outstanding will
constitute a quorum for the transaction of business. Abstentions will be
treated as present and entitled to vote, and therefore are counted in
determining the existence of a quorum and will have the effect of a vote
against any matter requiring the affirmative vote of a majority of the shares
present and entitled to vote at the Annual Meeting. In addition, broker "non-
votes" will be considered present but not entitled to vote, and thus will be
counted in determining the existence of a quorum but will not be counted in
determining whether a matter requiring approval of a majority of the shares
present and entitled to vote has been approved or whether a majority of the
vote of the shares present and entitled to vote has been cast.

   The Company will bear the entire cost of this solicitation, including the
preparation, assembly, printing and mailing of this Proxy Statement, the Proxy
Form, and our 1999 Annual Report. We intend to provide copies of such
solicitation materials to brokerage houses, fiduciaries, custodians and other
persons or entities
<PAGE>

holding our common stock on behalf of the beneficial owner so that the
solicitation materials may be forwarded to such beneficial owners. This
solicitation, which is being conducted by mail, may be supplemented by a
solicitation by telephone, telegram, or other permissible means by directors,
officers or employees of Pac-West. No additional compensation will be paid to
these individuals for conducting such a solicitation.

                                   PROPOSAL 1

                             ELECTION OF DIRECTORS

   Our by-laws provide that the authorized number of members of our board of
directors shall be nine. The board of directors is divided into three classes
of directors, with each class serving staggered three-year terms. Vacancies on
the board of directors are filled by a majority vote of the incumbent directors
and each director chosen in this manner holds office until the expiration of
the term for which such director's predecessor was elected and until a
successor is duly elected and qualified or until his or her earlier death,
resignation or removal pursuant to our by-laws. The board of directors
currently consists of seven directors and there are two vacant directorships.
Class I consists of David G. Chandler and Samuel A. Plum, and one vacant
directorship, whose terms expire at the 2002 annual meeting. Class II consists
of Mark S. Fowler and Dr. Jagdish N. Sheth, and one vacant directorship, whose
terms expire at the 2001 annual meeting. Class III consists of Wallace W.
Griffin, Jerry L. Johnson and John K. La Rue, whose terms expire at the 2000
annual meeting. The board of directors has not yet identified and nominated any
person(s) to fill the vacant Class I and Class II directorships. When the board
of directors identifies a person or persons to fill the vacant Class I and
Class II directorships, it will appoint such person(s) to serve on the board of
directors until the expiration of such directorships' respective terms. Each
director is elected to serve for the remaining term of any vacancy filled by
the director or for a three-year term (if elected at an annual meeting of
shareholders) or until a successor is duly elected.

   Messrs. Griffin, Johnson and La Rue have been nominated for re-election at
the Annual Meeting as Class III directors. See "Management--Nominees for
Director" and "Management--Continuing Directors" for information with respect
to Messrs. Griffin, Johnson and La Rue as well as our continuing directors. We
believe that each nominee is willing to be elected and to serve on our board of
directors. In the event that any nominee is unable to serve or is otherwise
unavailable for election, which is not now contemplated, the incumbent members
of the board of directors may or may not select a substitute nominee. If a
substituted nominee is selected, all proxies will be voted for the person
selected.

   Directors will be elected at the Annual Meeting by a majority of the votes
cast at the Annual Meeting by the holders of shares represented in person or by
proxy. There is no cumulative voting as to any matter, including the election
of directors.

   The board of directors recommends a vote "FOR" the election of the nominees.

                                   PROPOSAL 2

                         APPROVAL OF THE AMENDMENT AND
                               RESTATEMENT OF OUR
                 AMENDED AND RESTATED ARTICLES OF INCORPORATION

   The board of directors is proposing the amendment and restatement of our
Amended and Restated Articles of Incorporation (the "Articles of
Incorporation"), which would:

  . increase the number of authorized shares of our common stock, par value
    $0.001 per share from 50,000,000 shares to 100,000,000 shares;

  . authorize the issuance of 10,000,000 shares of preferred stock, with such
    preferences, privileges and restrictions as may be determined by the
    board of directors at a later date; and

  . remove authority to issue shares of Class A Participating Preferred
    Stock, par value $0.001 per share.

The Articles of Incorporation currently provide that the total number of shares
of capital stock that the Company has authority to issue is 51,750,000 shares,
consisting of 1,750,000 shares of Class A Preferred and 50,000,000 shares of
common stock.

   On May 2, 2000, the board of director adopted, subject to shareholder
approval, an amendment to the Articles of Incorporation to authorize the
issuance of 50,000,000 additional shares of common stock. If the proposed
amendment and restatement of the Articles of Incorporation is approved, an
aggregate of 100,000,000 shares of common stock would be authorized. The
additional authorized shares of common stock would be available for various
business purposes, including, but not limited to, acquisitions and employee
benefit plans. The issuance of additional shares of common stock or securities
convertible into common stock would have the effect of diluting the voting
rights and could have the effect of diluting earnings per share and book value
per share of the existing shareholders. In addition, the availability for
issuance of additional shares of common stock could have the effect of making
it more difficult for a third party to acquire control of us.

   On May 26, 2000, the board of directors adopted, subject to shareholder
approval, an amendment to the Articles of Incorporation that would authorize
the issuance of 10,000,000 shares of preferred stock issuable from time to time
in one or more series as determined by the board of directors and, except in
limited circumstances, without further vote or action by the shareholders. The
board of directors may determine the preferences, privileges and restrictions
of such preferred stock at the time that any preferred shares are issued. The
shares of preferred stock would be available for various business purposes. The
issuance of shares of preferred stock that would be convertible into common
stock would have the effect of diluting the voting rights, and would also have
the effect of diluting earnings per share and book value per share of the
existing shareholders. In addition, the availability for issuance of preferred
stock could have the effect of making it more difficult for a third party to
acquire control of us. We have no present intent to issue any additional shares
of preferred stock.

   On May 2, 2000, the board of directors adopted, subject to shareholder
approval, an amendment to the Articles of Incorporation to remove authority to
issue shares of its Class A Participating Preferred Stock. In connection with
our initial public offering of common stock in November 1999, all outstanding
shares of Class A Participating Preferred Stock were converted into our common
stock at the initial public offering price. If the proposed amendment and
restatement of the Articles of Incorporation is approved, we would no longer
have authority to issue Class A Participating Preferred Stock.

   As of April 30, 2000, there were no shares of Class A Participating
Preferred Stock outstanding and approximately 35,861,519 shares of common stock
outstanding. Of the remaining authorized but unissued shares of common stock,
approximately 3,150,000 shares were reserved for issuance under our stock
option plans. Accordingly, as of April 30, 2000, we have had approximately
10,988,481 shares of common stock remaining available for issuance.

                                       4
<PAGE>

   If approved, the Articles of Incorporation would be amended and restated in
its entirety as set forth in Exhibit A. To be approved, the amendment and
restatement of the Articles of Incorporation will must be approved by a
majority of the outstanding shares entitled to vote.

   The board of directors recommends a vote "FOR" the amendment and restatement
of the Company's Amended and Restated Articles of Incorporation.

                                   PROPOSAL 3

                   APPROVAL OF THE AMENDMENT AND RESTATEMENT
                   OF THE COMPANY'S 1999 STOCK INCENTIVE PLAN

Introduction

   We have established the Pac-West Telecomm, Inc. 1999 Stock Incentive Plan,
as amended and restated from time to time, in accordance with its terms (the
"Current Incentive Plan"), which authorizes the granting of stock options,
restricted stock, stock appreciation rights ("SARS"), dividend equivalent
rights, performance units, performance shares or other similar rights or
benefits to our or our related entities' current or future employees,
directors, and consultants. Under the Current Incentive Plan, the board of
directors is authorized to issue options to purchase shares of common stock in
such quantity, at such exercise prices, on such terms and subject to such
conditions as established by the board of directors. An aggregate of 3,150,000
shares of our common stock have been authorized and reserved for grants under
the Current Incentive Plan and the employment agreements of Wallace W. Griffin,
our President and Chief Executive Officer, and Richard E. Bryson, our Chief
Financial Officer, subject to adjustment upon the occurrence of certain events
to prevent any dilution or expansion of the rights of participants that might
otherwise result from occurrence of such events.

   On May 2, 2000, the board of directors adopted, subject to shareholder
approval, the amendment and restatement of the Current Incentive Plan (as
amended, the "Amended Incentive Plan"), which would increase the number of
shares of common stock authorized and reserved for grant by 2,225,000 shares
from 3,150,000 shares under the Current Incentive Plan to 5,375,500 shares
under the Amended Incentive Plan and make certain changes to the terms of the
plan described more fully below.

   The proposed increase in the number of shares of common stock authorized and
reserved for grant under the Amended Incentive Plan is intended to ensure that
the Company will maintain sufficient equity incentives to attract and retain
the best available personnel, to provide additional incentive to employees,
directors, and consultants, and to promote the success of the Company's
business. In addition, the Amended Incentive Plan would adopt a limit on the
maximum number of common stock with respect to which options may be granted to
any grantee in any fiscal year of the company and certain other administrative
provisions to comply with the performance-based compensation exception to the
deduction limit of Section 162(m) of the Internal Revenue Code of 1986, as
amended (the "Code").

   If approved, the Current Incentive Plan would be amended and restated in its
entirety as set forth in Exhibit B. To be approved, the amendment and
restatement must be approved by a majority of the votes cast at the Annual
Meeting by the holders of shares represented in person or by proxy.

   The summary of the Amended Incentive Plan that appears below is qualified by
reference to the full text of the Amended Incentive Plan set forth in Exhibit
B.

Types of Awards

   The board of directors or any committee thereof appointed to administer the
Amended Incentive Plan (the "Administrator") is authorized under the plan to
award any type of arrangement to an employee, director or consultant that is
not inconsistent with the provisions of the plan and that by its terms involves
(i) shares of common stock, (ii) an option, SAR, or similar right, or (iii) any
other security with the value derived from the value of shares of common stock,
including, but not limited to options, sales or bonuses of restricted stock,
SARs, dividend equivalent rights, performance units or performance shares, or
any combination thereof.

Term

   The Amended Incentive Plan will terminate on January 29, 2009 unless sooner
terminated by the board of directors. Termination of the Amended Incentive Plan
will not affect grants made prior to termination, but no grants will be made
after termination.

                                       6
<PAGE>

Administration

   The Amended Incentive Plan is administered by our compensation committee,
with authority delegated by the board of directors. The Administrator of the
Amended Incentive Plan has the authority to: (i) select the employees,
directors and consultants to whom awards may be granted; (ii) determine whether
and to what extent awards are granted; (iii) determine the number of shares or
other amount of consideration to be covered by each award; (iv) approve forms
of agreements in connection with the awards; (v) determine the terms and
conditions of any award; (vi) establish additional terms, conditions, rules or
procedures to accommodate the rules or laws of applicable foreign jurisdictions
and to afford grantees favorable treatment under such rules or laws; (vii)
amend the terms of any outstanding award, subject to certain limitations
requiring the consent of grantees; (viii) construe and interpret the terms of
the plan; and (ix) take other action, not inconsistent with the plan, as the
Administrator deems appropriate.

   Any grants of awards to an employee who is a covered employee intended to
qualify as performance-based compensation under the Code shall be made only by
a committee, which is comprised solely of two or more directors eligible to
serve on such committee.

Eligibility

   Awards other than incentive stock options may be granted to employees,
directors and consultants. Incentive stock options may be granted only to
employees of the Company, a parent, or subsidiary. An employee, director or
consultant who has been granted an award may, if otherwise eligible, be granted
additional awards. Awards may be granted to such employees, directors, or
consultants who are residing in foreign jurisdictions as the administrator of
the plan may determine.

Securities Subject to the Incentive Plan

   An aggregate of 5,375,000 shares of common stock may be issued pursuant to
the Amended Incentive Plan, which includes grants under the employment
agreements of Messrs. Griffin and Bryson. This represents an increase of
2,225,000 shares from the 3,150,000 shares of common stock authorized and
reserved under the Current Incentive Plan. The Company has filed with the
Securities and Exchange Commission (the "SEC") a registration statement on Form
S-8 under the Securities Act of 1933, as amended (the "Securities Act"),
covering common stock to be offered pursuant to the Current Incentive Plan. It
is currently anticipated that a registration statement on Form S-8 under the
Securities Act will be filed with the SEC, covering the shares of common stock
to be offered pursuant to the Amended Incentive Plan if approved by the
shareholders.

   Any shares of common stock covered by an award that is forfeited or
canceled, expires or is settled in cash, shall be deemed not to have been
issued for purposes of determining the maximum aggregate number of shares of
common stock that may be issued under the Amended Incentive Plan. If any
unissued shares of common stock are retained for such award or any withholding
taxes due with respect to such award, such retained shares of common stock
shall become available for future issuance under the Amended Incentive Plan.
Shares that actually have been issued under the Amended Incentive Plan pursuant
to an award shall not be returned to the plan and shall not become available
for future issuance under the plan, except that if unvested shares of common
stock are forfeited, or repurchased by the Company at their original purchase
price, such shares shall become available for future grant under the plan.

   Subject to any required action by shareholders of the Company, the number of
shares of common stock covered by each outstanding award, and the number of
shares of common stock that have been authorized for issuance under the plan,
but as to which no awards have yet been granted or that have been returned to
the plan, the exercise or purchase price of each such outstanding award, as
well as any other terms that the Administrator of the plan determines require
adjustment shall be proportionately adjusted for (i) any stock split, reverse
stock split, stock dividend, combination or reclassification of the shares of
common stock, (ii) any other increase or decrease in the number of issued
shares of common stock effected without receipt of consideration

                                       7
<PAGE>

by the Company, or (iii) as the Administrator of the plan may determine in its
discretion. Except as the Administrator of the plan determines, no issuance by
the Company of shares of common stock of any class, or securities convertible
into shares of common stock of any class, shall effect, and no adjustment shall
be made with respect to, the number or price of shares of common stock subject
to an award.

   In the event of (i) any merger or consolidation in which the Company is not
the surviving entity, (ii) the sale, transfer or other disposition of all or
substantially all of the assets of the Company in connection with the complete
liquidation or dissolution of the Company, (iii) any reverse merger in which
the Company is the surviving entity but in which voting control is transferred
to a third party, or (iv) an acquisition of voting control of the Company's
securities, all awards under the plan shall terminate immediately prior to such
transaction unless the award is assumed by the successor corporation or its
parent in connection with the transaction. Upon the occurrence of such a
transaction any awards held by the Company's Chief Executive Officer, Chief
Financial Officer and Executive Vice President will become fully vested and
exercisable, and 50% of any awards held by the Company's Vice President of
Business Development will become fully vested and exercisable, immediately
prior to such transaction.

Terms and Conditions of Awards

   Each award shall be designated in the award agreement. The Administrator
shall, subject to the terms of the Incentive Plan, determine the provisions,
terms, and conditions of each award, including but not limited to, the vesting
schedule, repurchase provisions, rights of first refusal, forfeiture
provisions, form of payment, payment contingencies and satisfaction of
performance criteria. In the case of an option, the option shall be designated
as either an incentive stock option or a non-qualified stock option.
Notwithstanding such designation, to the extent that the aggregate fair market
value of shares subject to options designated as incentive stock options that
become exercisable for the first time by a grantee during any calendar year
exceeds $100,000 on the date of grant, such excess options shall be treated as
non-qualified options.

   The term of each award shall be the term stated in the award agreement,
provided that the term does not exceed ten (10) years from the date of grant.
In the case of an incentive stock option granted to a grantee, who at the time
the option is granted, owns stock representing more than ten (10) percent of
the voting power of all classes of stock of the Company or related entities,
the term of the incentive stock option shall be not more than five (5) years
from the date of the grant.

   Under the Amended Incentive Plan, the maximum number of shares with respect
to which options or SARs may be granted to any grantee in any fiscal year of
the Company shall be 500,000 shares. In connection with a grantee's
commencement of employment, a grantee may be granted options and SARs for up to
an additional 500,000 shares. In each case, such limitation shall be adjusted
in connection with changes in capitalization or a corporate transaction. The
aforementioned limitation was not provided for in the Current Incentive Plan.

   Incentive stock options may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised during the lifetime of the grantee
only by the grantee. The grantee, however, may designate a beneficiary of the
grantee's incentive stock option in the event of the grantee's death. Other
awards may be transferred by gift or through a domestic relations order to
members of the grantee's immediate family.

Award Exercise or Purchase Price

   The exercise or purchase price for an award of incentive stock options or an
award of non-qualified stock options to an employee who at the time the option
is granted, owns stock representing more than ten (10) percent of the voting
power of all classes of stock of the Company or related entities the exercise
price shall not be less than one hundred and ten (110) percent of the fair
market value of the shares on the date of the grant. In the case of the sale of
shares of common stock to such an employee, the purchase price shall also not
be less than one hundred and ten (110) percent of the fair market value of the
shares on the date of the grant.

                                       8
<PAGE>

   The exercise purchase price, if any, for an award of incentive stock options
to an employee who at the time the option is granted, owns stock representing
ten (10) percent or less of the voting power of all classes of stock of the
Company or related entities shall not be less than one hundred (100) percent of
the fair market value of the shares on the date of grant. In the case of a
grant of non-qualified stock options or the sale of shares of common stock, the
exercise or purchase price to such employees shall not be less than eighty-five
(85) percent of the fair market value of the shares on the date of the grant.

   Subject to applicable laws, the consideration to be paid for the shares to
be issued upon exercise or purchase of an award, including method of payment,
shall be determined by the Administrator. The Administrator is authorized to
accept as consideration for shares of common stock under the plan cash, check,
promissory note, surrender of shares of common stock, or, in the case of
options, payment through a broker-dealer.

Exercise of Awards

   Any award granted under the Amended Incentive Plan shall be exercisable at
such times and under such conditions as the Administrator may determine under
the Amended Incentive Plan and as specified in the award agreement. In the case
of an option, awards may not be exercisable at a rate of less than twenty (20%)
percent per year over five (5) years from the date the option is granted.

Effect of Termination of Employment

   If a grantee terminates employment with the Company (but not in the event of
a grantee's change of status from employee to consultant), such grantee may,
for the period specified in the award agreement (but not less than three (3)
months) following termination, exercise the award, provided that the award has
not previously expired by its terms. The award agreement may provide that an
employee terminated for cause may not exercise following termination. In the
event of the grantee's disability or death, such grantee or the grantee's
estate (or a person who has acquired right to exercise by inheritance) may, for
the period specified in the award agreement (but not less than twelve (12)
months) following termination as a result of disability or death, exercise the
award, provided the award has not previously expired by its terms.

Certain Federal Income Tax Consequences

   The following is intended only as a brief summary of the Federal income tax
rules relevant to recipients of awards under the Amended Incentive Plan and
does not purport to be a complete enumeration or analysis of all potential
relevant tax effects. These rules are highly technical and subject to change in
the future. It is accordingly recommended that all award recipients consult
their own tax advisors concerning federal, state, local and foreign income and
other tax considerations relating to such awards and rights thereunder. In
particular, it is recommended that each award recipient consult his or her own
tax advisor as to the AMT (as defined below) consequences of an award and the
special tax considerations for a 16(b) Person (as defined below) and whether
and when to make a Section 83(b) Election (as defined below), using a stock
swap or stock withholding, utilizing financial assistance from the Company or
receiving an award in connection with a deferral of compensation.

   Non-qualified Stock Options. An optionee does not recognize any taxable
income, and the Company is not entitled to a deduction, upon the grant of a
non-qualified option. Upon the exercise of a non-qualified option, the optionee
recognizes ordinary income (subject to wage and employment tax withholding)
equal to the excess of the fair market value of the shares acquired over the
option price. The amount of such excess is generally determined by reference to
the fair market value of the common stock on the date of exercise. However, in
the case of an optionee subject to six month short-swing profit liability under
Section 16(b) of the Exchange Act (a "16(b) Person") (typically, officers,
directors and major shareholders of the Company), such excess is determined by
using the fair market value on the date of exercise (or, if later, the date six
months after the date of grant unless such optionee elects to be taxed based on
the fair market value of the common stock on the date

                                       9
<PAGE>

of exercise by filing an appropriate election with the Internal Revenue Service
within 30 days after the exercise date (a "Section 83(b) Election")). An
optionee's basis in the stock received is equal to such stock's fair market
value on the date of exercise (or on the date six months after the date of
grant, if later, in the case of an optionee who is a 16(b) Person and who makes
no Section 83(b) Election at the time of exercise). Generally, the Company is
entitled to a deduction equal to the compensation taxable to the optionee.

   If an optionee sells shares acquired pursuant to the exercise of a non-
qualified option, the optionee will recognize capital gain or loss equal to the
difference between the selling price of the shares and the optionee's basis in
the shares. Such capital gain or loss is long-term or short-term, depending on
whether the optionee has held the shares for more than one year. In the case of
an optionee who is a 16(b) Person and who makes no Section 83(b) Election at
the time of exercise, any such capital gain will be long-term only if the stock
has been held for more than one year after the later of the exercise date or
the date six months after the date of grant. The Company is not entitled to any
deduction with respect to any capital gain recognized by the optionee.

   Capital losses on the sale of such shares may be used to offset capital
gains. The net capital gain of an individual taxpayer is subject to a maximum
rate of 20% for the sale of capital assets held more than one year or a maximum
rate of 39.6% (the maximum ordinary income tax rate) for the sale of capital
assets held one year or less. If capital losses exceed capital gains, then up
to $3,000 of the excess losses may be deducted from ordinary income. Remaining
capital losses may be carried forward to future tax years.

   Incentive Stock Options. In general, an optionee does not recognize taxable
income on the grant or exercise of an incentive stock option. However, the
excess of the stock's fair market value on the exercise date (the fair market
value on the exercise date or six months after the date of grant, whichever is
later, is likely to govern in the case of a 16(b) Person who makes no Section
83(b) Election at the time of exercise) over the option price will be included
in the optionee's alternative minimum taxable income and thereby may subject
the optionee to an alternative minimum tax. Such alternative minimum tax may be
payable even though the optionee receives no cash upon the exercise of his or
her incentive stock option with which to pay such tax. Upon the disposition of
shares of common stock acquired pursuant to the exercise of an incentive stock
option (i) more than one year after the date of exercise, and (ii) more than
two years after the date of grant, the optionee recognizes long-term capital
gain or loss, as the case may be, measured by the difference between the
stock's selling price and the exercise price. The Company is not entitled to
any tax deduction by reason of the grant or exercise of an incentive stock
option, or a disposition of stock received upon the exercise of an incentive
stock option after the required holding period has been satisfied.

   If an optionee disposes of the shares of stock acquired pursuant to the
exercise of an incentive stock option before the expiration of the required
holding period described above (a disqualifying disposition), the difference
between the exercise price of such shares and the lesser of (i) the fair market
value of the shares on the date of exercise (the fair market value on the
exercise date or on the date which is six months after the date of grant,
whichever is later, is likely to govern in the case of a 16(b) Person who makes
no Section 83(b) Election at the time of exercise), or (ii) the selling price,
will constitute compensation taxable to the optionee as ordinary income.
Generally, in the case of a disqualification disposition, the Company is
allowed a corresponding tax deduction equal to the amount of compensation
taxable to the optionee. If the selling price of the stock exceeds the fair
market value on the exercise date (or six months after the date of grant, if
later, in the case of a 16(b) Person who makes no Section 83(b) Election), the
excess will be taxable to the optionee as capital gain (long-term or short-
term, depending upon whether the optionee held the stock for more than one
year). The Company is not allowed a deduction with respect to any such capital
gain recognized by the optionee.

   Use of Common Stock to Pay Option Price. If an optionee delivers previously-
acquired common stock, however acquired, in payment of all or part of the
option price of a non-qualified option, the optionee will not, as a result of
such delivery, be required to recognize as taxable income or loss any
appreciation or depreciation in the value of the previously-acquired common
stock after its acquisition date. The optionee's tax basis in, and

                                       10
<PAGE>

holding period for, the previously-acquired common stock surrendered carries
over to an equal number of the option shares received on a share-for-share
basis. The fair market value of the shares received in excess of the shares
surrendered constitutes compensation taxable to the optionee as ordinary
income. Such fair market value is determined on the date of exercise, except in
the case of 16(b) Persons as discussed above. The tax basis for such shares is
equal to their fair market value as so determined, and with respect to such
shares, the holding period begins on the date on which the fair market value of
such shares is determined. Generally, the Company is entitled to a tax
deduction equal to the compensation income recognized by the optionee.

   If an optionee delivers previously-acquired common stock (other than stock
acquired upon exercise of an incentive stock option and not held for the
required holding period) in payment of all or part of the option price of an
incentive stock option, the optionee will not be required to recognize as
taxable income or loss any appreciation or depreciation in the value of the
previously-acquired common stock after its acquisition date. The optionee's tax
basis in, and holding period (for capital gain, but not disqualifying
disposition, purposes) for the previously-acquired stock surrendered carries
over to an equal number of the option shares received on a share-for-share
basis. Shares received in excess of the shares surrendered have a tax basis
equal to the amount paid (if any) in excess of the previously-acquired shares
used to pay the exercise price, and such shares' holding period will begin on
the date of exercise (with the possible exception of 16(b) Persons). Proposed
regulations provide that where an incentive stock option is exercised using
previously-acquired stock, a later disqualifying disposition of the shares
received will be deemed to have been a disposition of the shares having the
lowest basis first.

   If an optionee pays the exercise price of an incentive stock option in whole
or in part with previously-acquired common stock that was acquired upon the
exercise of an incentive stock option and that has not been held for the
required holding period, the optionee will recognize ordinary income (but not
capital gain) under the rules applicable to disqualifying dispositions. The
Company will be entitled to a corresponding deduction. The optionee's basis in
the shares received in exchange for the shares surrendered will be increased by
the amount of ordinary income recognized by the optionee.

   Stock Appreciation Rights. A grantee does not recognize any taxable income,
and the Company is not entitled to a deduction, upon the grant of an SAR. Upon
the exercise of an SAR, the grantee will recognize ordinary income equal to the
amount of (i) cash payable to the grantee (if any) and (ii) the fair market
value of the common stock distributed to the grantee (if any) by reason of such
exercise.

   Restricted Stock. An officer, employee or other individual who receives
common stock pursuant to a restricted stock award should not recognize any
taxable income upon the receipt of such award unless he or she makes a Section
83(b) Election. Instead, the recipient should recognize taxable compensation
income at the time his or her interest in such shares is no longer subject to
the repurchase option imposed by the Incentive Plan, in an amount equal to the
fair market value of such shares at such time minus the amount, if any, paid
for such shares. The tax basis of such shares to the recipient should be equal
to the amount includable in his or her gross income as compensation, plus the
amount, if any, paid for such shares, and his or her holding period for such
shares should normally commence on the day following the date on which such
shares are no longer subject to the repurchase option imposed by the Incentive
Plan. Dividends paid on restricted stock awards should be included as
compensation for federal income tax purposes when received. In lieu of being
taxed under the foregoing rules, the recipient may elect to be taxed on
compensation income equal to the fair market value of the shares on the award
date minus the amount, if any, paid for such shares by making a Section 83(b)
Election no later than 30 days after the award date. If a recipient makes a
Section 83(b) Election, his or her tax basis in his or her shares should be
equal to the amount includable in his or her gross income as compensation plus
the amount, if any, paid for such shares, and his or her holding period in the
shares should begin on the day following the award date.

   Performance Awards. An officer, employee or other individual to whom a
performance unit is awarded should recognize no taxable income at the time such
award is made. Such person should recognize taxable income, however, at the
time cash is paid to him or her pursuant to such award, and the amount of such
income should be the amount of such cash.

                                       11
<PAGE>

   Limits on Company Deductions. The company for which an individual is
performing services will generally be allowed to deduct amounts that are
includable in the income of such person as ordinary compensation income at the
time such amounts are so includable, provided that such amounts qualify as
reasonable compensation for personal services actually rendered. However, if,
in any taxable year, an employee's total compensation from the company exceeds
$1 million, compensation in excess of $1 million that would otherwise be
deductible by the company may not be tax deductible under Code Section 162(m)
if such employee is a "covered employee" at the time the compensation is
included in the employee's taxable income. An employee is a covered employee if
he or she is (1) the chief executive officer or is an individual acting in such
capacity, or (2) one of the four most highly compensated employees (other than
the chief executive officer) employed by the company at the end of the taxable
year, whose compensation is required to be disclosed under the Exchange Act at
the end of the company's taxable year. Compensation that is "performance-based"
within the meaning of Code Section 162(m) is excluded from the calculation of
taxable income subject to the $1 million deduction limit. The Company intends
that compensation realized upon the exercise of an option or SAR granted under
the Incentive Plan be regarded as "performance-based" under Code Section 162(m)
and that such compensation be deductible without regard to the limits of Code
Section 162(m).

   The Board of Directors recommends a vote "FOR" the approval of the amendment
and restatement of the Company's Current Incentive Plan.

                                   PROPOSAL 4

               ADOPTION OF THE 2000 EMPLOYEE STOCK PURCHASE PLAN

Introduction

   On May 2, 2000, the board of directors adopted, subject to shareholder
approval, the 2000 Employee Stock Purchase Plan (the "Stock Purchase Plan"),
which would provide employees of the Company who participate in the Stock
Purchase Plan with an opportunity to purchase common stock of the Company
through payroll deductions.

   The proposed adoption of the Stock Purchase Plan is intended to ensure that
the Company will maintain sufficient equity incentives to attract and retain
the best available personnel, to provide additional incentive to employees, and
to promote the success of the Company's business.

   If approved, the Stock Purchase Plan would be adopted as set forth in
Exhibit C. To be approved, the adoption of the Stock Purchase Plan will must be
approved by a majority of the votes cast at the Annual Meeting by the holders
of shares represented in person or by proxy.

   The summary of the Stock Purchase Plan that appears below is qualified in
its entirety by reference to the full text of the Stock Purchase Plan set forth
in Exhibit C.

General

   The Stock Purchase Plan and the right of participants to make purchases
thereunder is intended to qualify as an "employee stock purchase plan" under
the provisions of Section 423 of the Code. Employees of the Company and its
designated subsidiaries are eligible to participate in the Stock Purchase Plan.
Directors who are not employees are not eligible to participate. Any person who
has been employed by the Company (or any of its majority-owned subsidiaries for
whom the appropriate regulatory filings and action by the board of directors
have been made) for at least 30 days, and works at least 20 hours per week and
more than five months in a calendar year is eligible to participate in the
Stock Purchase Plan provided that the employee is employed on the enrollment
date (the first day of an Offer Period) and subject to certain limitations
imposed by Section 423(b) of the Code. Eligible employees become participants
in the Stock Purchase Plan by delivering to the Company a subscription
agreement authorizing payroll deductions at least 10 days prior to the
enrollment date of the applicable offer period.

   An aggregate of 1,000,000 shares of the Company's common stock will be
reserved for issuance under the Stock Purchase Plan and made available for
purchase thereunder, subject to adjustment in the event of a stock split, stock
dividend or other similar change in the common stock or the capital structure
of the Company. Under the Stock Purchase Plan, an option is granted to each
participant at the commencement of each six-month period (an "Offer Period")
during which deductions are made from the pay of participants (in accordance
with their authorizations) and credited to their accounts under the Stock
Purchase Plan. The Administrator may specify purchase periods (shorter periods
within an Offer Period) such that the option granted on the enrollment date
shall be automatically exercised in successive installments on the last day of
each purchase period ending within the Offer Period. A new six-month Offer
Period commences on or about each January 1 and July 1. Payroll deductions may
be from 1% to 10% (in whole percentage increments) of a participant's
compensation. Participants may not make direct cash payments to their accounts.
The maximum number of shares of common stock any employee may purchase in any
Offer Period is 400 shares. Certain additional limitations on the amount of
common stock which may be purchased in any calendar year are imposed by the
Code. Notwithstanding the foregoing, (i) no employee will be permitted to
subscribe for shares under the Stock Purchase Plan if, immediately after the
grant of the option, the employee would own 5% or more of the voting power or
value of all classes of stock of the Company or of a parent or of any of its

                                       13
<PAGE>

subsidiaries (including stock which may be purchased under the Stock Purchase
Plan or pursuant to any other options), and (ii) no employee shall be granted
an option which would permit the employee to buy pursuant to the Stock Purchase
Plan more than $25,000 worth of stock (determined at the fair market value of
the shares at the time the option is granted) in any calendar year.

   The price per share at which shares of common stock are purchased pursuant
to the Stock Purchase Plan for any purchase period is the lesser of (a) 85% of
the fair market value of common stock on the date of the grant of the option
(the commencement of each Offer Period) or (b) 85% of the fair market value of
common stock on the date of exercise of the option. Fair market value of the
common stock for any date shall be the closing sales price for the common stock
on the market trading day prior to the date of determination. On the last
business day of each purchase period, amounts credited to the accounts of the
participants who have neither been terminated from the employ of the Company
(or designated subsidiary) nor withdrawn from the Stock Purchase Plan for such
Offer Period are used to purchase shares of common stock. Only amounts credited
to the accounts of participants may be applied to the purchase of shares of
common stock under the Stock Purchase Plan. The number of shares of common
stock which may be purchased is subject to adjustment in the event of a stock
split, stock dividend or other similar change in the common stock or the
capital structure of the Company. If the Administrator determines that on a
given exercise date the number of shares with respect to which options are to
be exercised may exceed (a) the number of shares then available for sale under
the Stock Purchase Plan, or (b) the number of shares available for sale under
the Stock Purchase Plan on the Enrollment Dates of one or more of the Offer
Periods in which such Exercise Date is to occur, the Administrator is
authorized to apportion the available shares remaining on such Enrollment Dates
or Exercise Dates pro rata among participating employees on the basis of their
election in effect for such Offer Period, and shall either continue all Offer
Periods then in effect or terminate any one or more Offer Periods then in
effect.

   The Company makes no cash contributions to the Stock Purchase Plan, but
bears the expenses of administration. The Stock Purchase Plan is administered
by either the Board of Directors of the Company or a committee of the Board,
which has the authority to determine the terms and conditions under which
shares are to be offered and corresponding options are to be granted under the
Stock Purchase Plan for any Offer Period during the term of the Stock Purchase
Plan, and to resolve all questions immediately relating to the administration
of the Stock Purchase Plan.

   The Stock Purchase Plan will terminate on the date preceding the twentieth
anniversary of its date of adoption, unless earlier terminated by the
Administrator. A participant may increase or decrease the rate of his or her
payroll deduction for the remainder of an Offer Period by filling out the
appropriate form and delivering it to the Company (or its designee). The new
rate will become effective with the first full payroll period commencing 10
days after the Company receives the form unless the Company elects to process
changes more quickly, and will remain in effect for the entire Offer Period and
each subsequent Offer Period. A participant's interest in a given purchase
period may be terminated in whole, but not in part, by signing and delivering
to the Company a notice of withdrawal from the Stock Purchase Plan. Such
withdrawal may be elected at any time prior to the applicable exercise date.
Any withdrawal by the participant of accumulated payroll deductions for a given
Offer Period automatically terminates the participant's interest in that Offer
Period. The failure to remain in the continuous employ of the Company (or a
designated subsidiary) for at least 20 hours per week and more than five months
in a calendar year during an Offer Period will be deemed to be a withdrawal
from that Offer Period. No rights or accumulated payroll deductions of a
participant under the Stock Purchase Plan may be pledged, assigned or
transferred for any reason and any such attempt may be treated by the Company
as an election to withdraw from the Stock Purchase Plan.

Certain Federal Income Tax Consequences

   The following discussion summarizes certain tax considerations for
participants in the Stock Purchase Plan and certain tax effects to the Company.
State, local and foreign tax consequences may differ. Amounts deducted from a
participant's pay under the Stock Purchase Plan are part of the employee's
regular compensation and remain subject to federal, state and local income and
employment withholding taxes. A participant will not

                                       14
<PAGE>

recognize any additional income at the time the participant elects to
participate in the Stock Purchase Plan, or purchases common stock under the
Stock Purchase Plan. If a participant disposes of common stock purchased
pursuant to the Stock Purchase Plan within two years after the first day of the
Offer Period or within one year of the purchase of common stock (the "Minimum
Holding Period"), the participant will recognize, for federal tax purposes,
ordinary compensation income at the time of disposition of the common stock in
an amount equal to the excess of the fair market value of the common stock on
the day the common stock was purchased over the purchase price the participant
paid for the common stock. This amount may be subject to withholding for taxes.
In addition, a participant generally will recognize a capital gain or loss in
an amount equal to the difference between the amount realized upon the
disposition of the common stock and the participant's basis in the common stock
(that is, the purchase price plus the amount taxed as compensation income). If
a participant disposes of common stock purchased pursuant to the Stock Purchase
Plan at any time after the Minimum Holding Period, the participant will
recognize, for federal tax purposes, ordinary compensation income at the time
of such disposition in an amount equal to the lesser of (a) the excess (or zero
if there is no excess) of the fair market value of the common stock at the time
of such disposition over the amount paid for the common stock, or (b) 15% of
the fair market value of the common stock on the first day of the purchase
period. In addition, the participant generally will recognize a capital gain or
loss in an amount equal to the difference between the amount realized upon the
disposition of the common stock and the participant's basis in the stock (that
is, the purchase price plus the amount, if any, taxed as compensation income).

   Although the amounts deducted from a participant's pay under the Stock
Purchase Plan generally are tax-deductible business expenses of the Company,
the Company generally will not be allowed any additional deduction by reason of
a participant's purchase of common stock under the Stock Purchase Plan.
However, if a participant disposes of common stock purchased pursuant to the
Stock Purchase Plan within the Minimum Holding Period, the Company should be
entitled to a deduction in an amount equal to the compensation income
recognized by the participant (subject to the requirements of reasonableness
and perhaps, in the future, the satisfaction of a withholding obligation). If a
participant disposes of common stock purchased under the Stock Purchase Plan
after the Minimum Holding Period, the Company will not receive any deduction
for federal income tax purposes with respect to the common stock.

   The board of directors recommends a vote "FOR" adoption of the Company's
2000 Employee Stock Purchase Plan.

                                   PROPOSAL 5

         RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

   The board of directors, upon recommendation of its audit committee, has
selected the accounting firm of Arthur Andersen LLP to serve as our independent
auditors with respect to the 2000 fiscal year to examine our financial
statements for the fiscal year ending December 31, 2000 and to perform other
appropriate accounting services.

   Representatives of Arthur Andersen LLP are expected to be present at the
Annual Meeting to respond to questions and to make a statement if they desire
to do so. If the shareholders do not ratify this appointment by the affirmative
vote of a majority of the shares represented in person or by proxy at the
Annual Meeting, the board of directors upon recommendation will consider other
independent public accountants by the audit committee.

   To be approved, the appointment of Arthur Andersen LLP to serve as our
independent auditors must be ratified by a majority of the votes cast at the
Annual Meeting by the holders of shares represented in person or by proxy.

   The board of directors recommends a vote "FOR" ratification of the
appointment of Arthur Andersen LLP as our independent public accountants for
fiscal 2000.

Information About the Board of Directors

in accordance with a shareholders agreement that was entered into in connection

agreement relating to the nomination and election of directors terminated upon
completion of the Company's initial public offering in November 1999. There are
no family relationships between any of our directors or executive officers. Our
executive officers are elected by and serve at the discretion of the board of
directors.

   The board of directors met eight times during fiscal 1999. The board of
directors has a standing audit, compensation and executive committees. Each
director attended 75% or more of the meetings of the board of directors and any
committees on which such director served during fiscal 1999.

                                       19
<PAGE>

   Audit Committee. The audit committee is currently composed of three
directors: Messrs. Chandler, Fowler and Sheth. The audit committee makes
recommendations to the board of directors regarding the selection of
independent auditors, reviews the independence of such auditors, approves the
scope of the annual audit activities of the independent auditors and reviews
such audit results. The audit committee met three times during fiscal 1999.

   Compensation Committee. The compensation committee is currently composed of
two directors: Messrs. Fowler and Plum. The compensation committee makes
recommendations to the board of directors regarding the compensation of our
officers, awards under our compensation and benefit plans and compensation
policies and practices. The compensation committee met three times during
fiscal 1999.

   Executive Committee. The executive committee is currently composed of four
directors: Messrs. Chandler, Griffin, Johnson and Plum.

Compensation of Directors

   Directors who are employed by us, including Mr. Griffin and Mr. La Rue, and
directors who are affiliated with our principal shareholders, including Messrs.
Chandler, Johnson and Plum, are not currently entitled to receive any
compensation for serving on our board of directors. Our outside directors,
Messrs. Fowler and Sheth, receive $5,000 per quarter as compensation for
serving on our board of directors. In 1999, we granted each of Messrs. Fowler
and Sheth stock options to purchase 35,000 shares of our common stock at a
strike price of $2.14. The stock options will vest over a three-year period
with 33 1/3% vesting at the end of each year. We pay for the reasonable out-of-
pocket expenses incurred by each director in connection with attending board
and committee meetings.

Compliance with Section 16(a) of the Securities Exchange Act of 1934

   Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
executive officers and directors, and persons who own more than ten percent of
a registered class of the Company's equity securities, to file reports of
ownership and changes in ownership with the SEC and the Nasdaq Stock Market, as
required. These persons are required by regulation of the Commission to furnish
the Company with copies of all Section 16(a) forms they file.

   Based solely on a review of the copies of such forms received by the
Company, or written representations from certain reporting persons that no Form
5s were required for those persons, the Company believes that during the fiscal
year ended December 31, 1999 the Company's executive officers, directors and
greater than ten percent beneficial owners complied with all applicable Section
16(a) filing requirements, except that Richard E. Bryson, Bay Alarm Company and
Samuel A. Plum each filed a Form 4 after the required filing date.

1999 Stock Incentive Plan

   The Current Incentive Plan authorizes the granting of stock options,
including restricted stock, SARS, dividend equivalent rights, performance
units, performance shares or other similar rights or benefits to our or our
subsidiaries' current or future employees, directors, consultants, advisors.
Under the Current Incentive Plan, the board of directors is authorized to issue
options to purchase shares of common stock in such quantity, at such exercise
prices, on such terms and subject to such conditions as established by the
board. An aggregate of 3,150,000 shares of common stock have been authorized
and reserved for option grants under the Current Incentive Plan and the
employment agreements of Messrs. Griffin and Bryson, subject to adjustment upon
the occurrence of certain events to prevent any dilution or expansion of the
rights of participants that might otherwise result from the occurrence of such
events. As described in this Proxy Statement, the board of directors has
adopted the amendment and restatement of the Current Incentive Plan. Among
other changes, the Amended Incentive Plan authorizes and reserves 5,375,500
shares of common stock for option grants. The Company's shareholders are being
asked to approve the Amended Incentive Plan in connection with the Annual
Meeting. As of December 31, 1999, we had granted options outstanding with
respect to 2,224,650 shares of common stock, including those granted under the
employment agreements. No options have been exercised through December 31,
1999.

   The amounts shown for realizable potential value are calculated assuming
that the market value of the common stock was equal to the exercise price per
share as of the date of grant of the options. This value is the approximate
price per share at which shares of the common stock would have been sold in
private transactions on or about the date on which the options were granted.
The dollar amounts under these columns assume a compounded annual market price
increase for the underlying shares of the common stock from the date of grant
to the end of the option term of 5% and 10%. This format is prescribed by the
SEC and is not intended to forecast future appreciation of shares of the common
stock. The actual value, if any, a named officer may realize will depend on the
excess of the market price for shares of the common stock on the date the
option is exercised over the exercise price. Accordingly, there is no assurance
that the value realized by a named officer will be at or near the value
estimated below.

   employment under the employment agreement plus the one-year period
   thereafter;

 . in the case of Mr. Griffin, base salary for the greater of the remainder of
   the term of employment under the employment agreement or the six-month
   period thereafter;

 . in the case of Mr. Bryson, base salary for one year following termination
   plus our payment of all health insurance premiums with respect to Mr.
   Bryson's continuation coverage rights under the Consolidated Omnibus Budget
   Reconciliation Act of 1985, as amended, or any similar statute or
   regulation then in effect, for a maximum of the one-year period after such
   termination; and

 . in the case of Mr. Mills base salary for the remainder of the term of
   employment under the employment agreement.

   If the employment period is terminated as a result of the executive's
disability, then the executive and/or his estate or beneficiaries, as the case
may be, will be entitled to receive benefits under our employee benefit
programs as in effect on the date of such termination to the extent permitted
under such programs and, in addition, will be entitled to receive:

 . an amount equal to that executive's base salary for the one-year period
   after the termination of the employment period; and

 . the amount of any annual bonus otherwise payable to the executive for the
   fiscal year in which executive's employment is terminated, except that the
   amount of any such annual bonus otherwise payable will be allocated on the
   basis of the number of days during such fiscal year that executive was
   employed by us.

   If the employment period is terminated as a result of the executive's death,
then the executive and/or his estate or beneficiaries, as the case may be, will
be entitled to receive benefits under our employee benefit programs as in
effect on the date of such termination to the extent permitted under such
programs and, in addition, will be entitled to receive the amount of any annual
bonus otherwise payable to the executive for the fiscal year in which the
executive's employment is terminated, except that the amount of any such annual
bonus otherwise payable will be allocated on the basis of the number of days
during such fiscal year that the executive was employed by us. If we terminate
the employment period for cause or if the executive resigns for any reason,
other than a termination without cause under the respective employment
agreement, then the executive will be entitled to receive his base salary
through the date of termination and we will have no further liability
whatsoever to executive.

   Each of the executives has agreed to forfeit any severance obligations owing
to such executives in the event they breach certain noncompetition provisions.

Compensation Committee Interlocks and Insider Participation

   The compensation committee of the board of directors currently consists of
three directors, none of which are executive officers or employees of our
company. There are no director interlocking relationships.

Compensation Committee Report on Executive Officers Compensation

   The compensation committee of the board of directors has prepared the
following report on policies with respect to the compensation of executive
officers.

   The compensation committee is responsible for establishing salaries,
incentives and other forms of compensation for our directors, officers and key
employees and for administering our equity incentive plans, including the 1999
Stock Incentive Plan and, if approved by the shareholders, the 2000 Stock
Purchase Plan, and other incentive and benefit plans.

   The Company has developed a compensation program designed to attract,
retain, and motivate executives, and to reinforce and complement sound
management practices. In addition, the compensation committee seeks to align
the executives' interests with those of the Company and its shareholders by
providing executives with the potential for equity ownership. Our compensation
program focuses on annual base salary; annual incentive compensation; and
performance-based compensation consisting of equity-based awards.

   The compensation committee focuses on the financial and operational
performance of the Company, the competitive nature of the marketplace, and
performance of the executive in determining an individual executive's annual
compensation package.

   Base salaries for our executive officers are determined by evaluating a
number of subjective factors, including, among others, the level and scope of
responsibilities associated with the position held, the experience of the
individual, and the individual's contribution to our performance. Some
attention is also given to base salaries for comparable positions at comparable
companies within our industry. No specific weight was given to any of these
factors because each of the factors was considered significant and the
relevance of certain factors varied among the executive officers.

   We consider the payment of cash bonuses an important component of the
incentive compensation provided to each of its executive officers. The
determination of whether bonuses should be paid or, if paid, the magnitude of
such bonuses, is based on a number of factors, including corporate and
individual performance, and is largely a subjective determination of the
compensation committee.

   The compensation committee uses grants of stock options to deliver a
competitive compensation package that motivates executives to make decisions
that will increase the value of our common stock, thus providing an appropriate
focus on our long-term growth.

   During 1999, Wallace W. Griffin, our President and Chief Executive Officer,
received an annual base salary established by an Employment Agreement, dated
September 16, 1998, entered into by the Company and Mr. Griffin prior to the
formation of the compensation committee. Mr. Griffin received an incentive
bonus which equaled 100% of his base salary on the basis of the Company's
performance in 1999, the achievement of certain goals, including completion of
the Company's initial public offering of common stock in November 1999, the
Company's continued expansion into new markets, and other subjective criteria
reviewed by the compensation committee.

   Mr. Griffin also was granted options to purchase an additional 137,847
shares of common stock at the initial public offering price of $10.00 per
share. This grant was based on the criteria described above and is designed to
further align Mr. Griffin's long-term interests with those of the Company and
its shareholders. The

                                       24
<PAGE>

compensation committee believes this compensation package is generally
competitive with the salaries of Chief Executive Officers in companies that
compete with us, although precise comparisons may be misleading because our
competitors include both start-up companies and companies of greater size than
us.

   The compensation committee believes that the executive compensation policies
described in this report are in the best interests of the Company and its
shareholders. The various compensation mechanisms used by us maintain an
appropriate balance between motivating achievement of short-term goals and
strategically leading in a direction to provide long-term success. The
compensation committee will continue to monitor the effectiveness of our total
compensation program to ensure that it meets our needs.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Recapitalization

   Our recapitalization was completed on September 16, 1998 in accordance with
the merger agreement between us, Bay Alarm Company and John K. La Rue, the
preexisting investors, and PWT Acquisition Corp. a corporation newly formed by
an equity investment group led by Safeguard 98 Capital, L.P. and William Blair
Capital Partners L.L.P. to effect the recapitalization.

   Under the merger agreement, Mr. La Rue and Bay Alarm Company were entitled
to receive additional consideration of up to $20 million in the event that
certain billings under dispute were received subject to the recapitalization.

   On September 9, 1999, Pac-West entered into a settlement agreement with
Pacific Bell regarding claims for unpaid reciprocal compensation under our
prior interconnection agreement. Under the terms of the settlement agreement,
Pacific Bell agreed to pay $20.0 million to Pac-West and $20.0 million in the
aggregate to Mr. La Rue and Bay Alarm Company in settlement of those claims. As
a result of these payments, the terms of our September 1998 merger agreement
requiring additional distributions to these shareholders have been satisfied.

   In accordance with the merger agreement, Mr. La Rue and Bay Alarm Company
have agreed to indemnify us and certain of our related parties for all
liabilities and other losses arising from, among other things:

     (1) any breach by Pac-West of any representation, warranty, covenant or
  agreement we made in the merger agreement or in any schedule, exhibit, or
  other related document;

     (2) any claims of any brokers, finders, our employees or consultants
  relating to the transactions contemplated by the merger agreement not
  specifically set forth in or contemplated by the merger agreement; or

     (3) any claim by any person other than PWT Acquisition Corp. or its
  affiliates with respect to, or arising as a result of, any reorganization,
  liquidation, dissolution, recapitalization, non due course borrowing,
  merger, consolidation, sale or purchase of assets or similar transactions
  proposed prior to closing of the merger; provided that Mr. La Rue and Bay
  Alarm Company receive notice of such loss within the applicable time
  periods set forth in the merger agreement.

   Subject to certain exceptions, Mr. La Rue and Bay Alarm Company do not have
any obligation to indemnify any of the indemnified parties from any losses
caused by the breach or alleged breach of any representation or warranty
contained in the merger agreement until the indemnified parties collectively
suffer related aggregate losses in excess of $500,000, which acts as a
deductible. Mr. La Rue and Bay Alarm Company have an obligation to indemnify
the indemnified parties for all losses suffered by any of the indemnified
parties in excess of the deductible, provided that Mr. La Rue and Bay Alarm
Company do not have any obligation to indemnify the indemnified parties from
such aggregate losses in excess of an indemnity cap of $15.0 million. Despite
the above, breaches or alleged breaches of certain post-closing covenants or
agreements contained in the merger agreement will not be subject to the
deductible or the indemnity cap.

   The merger agreement contains representations and warranties typical of
those kinds of agreements, including, for example, those relating to corporate
organization and capitalization, the valid authorization, execution, delivery
and enforceability of all transaction documents, the financial statements, the
absence of material adverse changes in the business, assets, financial
condition and results of operations, the absence of material undisclosed
liabilities, tax matters, the quality and title of personal and real property,
material contracts, intellectual property, employee benefits plans,
environmental matters, compliance with laws, governmental authorizations,
permits and licenses and insurance matters. Generally, our representations and
warranties expire thirty days after receipt of the audited financial statements
for fiscal 1999 except that those relating to tax matters survive until the
expiration of the applicable statute of limitations and certain other
representations and warranties which survive indefinitely.

   The foregoing summary of the material terms of the merger agreement and
related matters does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all of the provisions of the merger
agreement, including the definitions of certain terms therein and the exhibits
and schedules hereto.

Shareholders Agreements

   In connection with the acquisition of Installnet, Inc. and two other
related companies ("Installnet") in February 2000, we entered into a
shareholder agreement with the former shareholders of Installnet. The
shareholder agreement provides that the shareholders may not sell, offer to
sell or otherwise dispose of any shares of our common stock received in
connection with the acquisition until August 4, 2000, at which time 50% of the
shares of common stock issued to the shareholders will be released from these
restrictions. The remaining 50% of the shares will be released from these
restrictions on February 4, 2001.

Registration Agreement

   In connection with the recapitalization, all of our shareholders at that
time entered into a registration agreement. In accordance with the
registration agreement, at any time after May 7, 2000 each of the four equity
investors in the recapitalization may request one registration at our expense
under the Securities Act of 1933 of all or any portion of their Pac-West
common stock on Form S-1 or other similar long-form registration and an
unlimited number of Form S-2 or S-3 or other similar short-form registrations,
provided that the aggregate offering value of the registrable securities
requested to be registered in any long-form registration must equal at least
$5 million in all long-form registrations and at least $1 million in all
short-form registrations. In the event that any one of the four equity
investors in the recapitalization makes such a demand registration request,
all other parties to the registration agreement will be entitled to
participate in such registration. The registration agreement will also grant
to the parties thereto piggyback registration rights with respect to all other
registrations of our common stock and we, subject to limited exceptions, will
pay all expenses related to the piggyback registrations.

   In connection with the acquisition of Installnet in February 2000, we
entered into a registration rights agreement with the former shareholders of
Installnet. Pursuant to the terms of the registration rights agreement, the
shareholders were granted piggyback registration rights with respect to
certain offerings of our common stock, subject to the limitation on transfers
contained in the shareholder agreement between the shareholders and Pac-West.
As a result of these limitations, such shareholders are not eligible to
request registration of our common stock held by them in connection with this
offering.

Non-Competition; Non-Solicitation; Confidentiality Agreements

   In connection with the recapitalization and in accordance with the terms of
the merger agreement, Mr. La Rue and Bay Alarm Company each have entered into
a covenant not to compete with Pac-West, not to engage, and not to permit any
affiliate to engage, for a noncompete period of two years after the closing
date of the recapitalization in any business which:

     (1) provides telecommunication services of the type provided as of the
  closing date by Pac-West; or

     (2) provides services of the type which we have taken significant
  actions as of the closing date to begin providing or of the type we have
  indicated that we plan to begin providing in any business plan or similar
  document delivered to PWT Acquisition Corp. or our shareholders prior to
  the closing date, in each case within Arizona, California, Colorado, Idaho,
  Nevada, New Mexico, Oregon, Texas, Utah and Washington, the province of
  British Columbia, Canada and the territories and jurisdictions of Mexico.

   The noncompete restrictions do not prohibit any party from being a passive
owner of not more than 5% of the outstanding stock of any class of a
corporation which is publicly traded; and provided further that the noncompete
restrictions do not restrict the activities of any party to the extent such
party has received the consent of our board of directors to such activities.

   In accordance with their respective employment agreements, Messrs. La Rue,
Griffin, Bryson and Mills have agreed to forfeit any severance obligations
owing to such executives in the event of their breach of similar noncompetition
provisions. For purposes of Mr. Mills' agreement, the restricted territories
include Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon,
Texas, Utah and Washington, the province of British Columbia, Canada and the
territories and jurisdictions of Mexico. For purposes of Mr. Griffin's and Mr.
Bryson's respective agreements, the restricted territories include the United
States of America, Canada and the territories and jurisdictions of Mexico.

   Messrs. La Rue, Griffin, Bryson, Mills and Bay Alarm have also agreed to
maintain the confidentiality of our information and not to solicit our
employees and customers as provided in the merger agreement or their respective
employment agreements, as the case may be.

Other Transactions with Significant Stockholders

   Mr. Bruce A. Westphal, who served as our chairman of the board until the
recapitalization and as a director of the Company until March 16, 2000, is the
chairman of the board of both Bay Alarm Company and InReach Internet. As of
March 1, 2000, an affiliate of Bay Alarm Company held approximately 13.7% of
our outstanding common stock. Sales to Bay Alarm accounted for approximately

the years ended December 31, 1997, 1998 and 1999, respectively. In addition,
Bay Alarm Company provides us with security monitoring services at its normal

commercial space. The monthly lease payments under the lease are approximately
$13,000 effective December 1998. Sales to InReach Internet LLC accounted for

    intended to qualify as Performance-Based Compensation shall be made

    consideration to be covered by each Award granted hereunder;

                                      B-4
<PAGE>

       (iv) to approve forms of Award Agreements for use under the Plan;

       (v) to determine the terms and conditions of any Award granted
    hereunder;

       (vi) to establish additional terms, conditions, rules or procedures
    to accommodate the rules or laws of applicable foreign jurisdictions
    and to afford Grantees favorable treatment under such rules or laws;
    provided, however, that no Award shall be granted under any such
    additional terms, conditions, rules or procedures with terms or
    conditions which are inconsistent with the provisions of the Plan;

       (vii) to amend the terms of any outstanding Award granted under the
    Plan, provided that any amendment that would adversely affect the
    Grantee's rights under an outstanding Award shall not be made without
    the Grantee's written consent;

       (viii) to construe and interpret the terms of the Plan and Awards,
    including without limitation, any notice of award or Award Agreement,
    granted pursuant to the Plan; and

       (ix) to take such other action, not inconsistent with the terms of
    the Plan, as the Administrator deems appropriate.

     (d) Effect of Administrator's Decision. All decisions, determinations
  and interpretations of the Administrator shall be conclusive and binding on
  all persons.

   5. Eligibility. Awards other than Incentive Stock Options may be granted to
Employees, Directors and Consultants. Incentive Stock Options may be granted
only to Employees of the Company, a Parent or a Subsidiary. An Employee,
Director or Consultant who has been granted an Award may, if otherwise
eligible, be granted additional Awards. Awards may be granted to such
Employees, Directors or Consultants who are residing in foreign jurisdictions
as the Administrator may determine from time to time.

   6. Terms and Conditions of Awards.

     (a) Type of Awards. The Administrator is authorized under the Plan to
  award any type of arrangement to an Employee, Director or Consultant that
  is not inconsistent with the provisions of the Plan and that by its terms
  involves or might involve the issuance of (i) Shares, (ii) an Option, a SAR
  or similar right with a fixed or variable price related to the Fair Market
  Value of the Shares and with an exercise or conversion privilege related to
  the passage of time, the occurrence of one or more events, or the
  satisfaction of performance criteria or other conditions, or (iii) any
  other security with the value derived from the value of the Shares. Such
  awards include, without limitation, Options, sales or bonuses of Restricted
  Stock, SARs, Dividend Equivalent Rights, Performance Units or Performance
  Shares, and an Award may consist of one such security or benefit, or two
  (2) or more of them in any combination or alternative.

     (b) Designation of Award. Each Award shall be designated in the Award
  Agreement. In the case of an Option, the Option shall be designated as
  either an Incentive Stock Option or a Non-Qualified Stock Option. However,
  notwithstanding such designation, to the extent that the aggregate Fair
  Market Value of Shares subject to Options designated as Incentive Stock
  Options which become exercisable for the first time by a Grantee during any
  calendar year (under all plans of the Company or any Parent or Subsidiary)
  exceeds $100,000, such excess Options, to the extent of the Shares covered
  thereby in excess of the foregoing limitation, shall be treated as Non-
  Qualified Stock Options. For this purpose, Incentive Stock Options shall be
  taken into account in the order in which they were granted, and the Fair
  Market Value of the Shares shall be determined as of the grant date of the
  relevant Option.

     (c) Conditions of Award. Subject to the terms of the Plan, the
  Administrator shall determine the provisions, terms, and conditions of each
  Award including, but not limited to, the Award vesting schedule, repurchase
  provisions, rights of first refusal, forfeiture provisions, form of payment
  (cash, Shares, or other consideration) upon settlement of the Award,
  payment contingencies, and satisfaction of any performance criteria. The
  performance criteria established by the Administrator may be based on any
  one of, or combination of, increase in share price, earnings per share,
  total shareholder return, return on equity, return on assets, return on
  investment, net operating income, cash flow, revenue, economic value added,
  personal management objectives, or other measure of performance selected by
  the Administrator. Partial achievement of the specified criteria may result
  in a payment or vesting corresponding to the degree of achievement as
  specified in the Award Agreement.


                                      B-5

     (d) Acquisitions and Other Transactions. The Administrator may issue
  Awards under the Plan in settlement, assumption or substitution for,
  outstanding awards or obligations to grant future awards in connection with
  the Company or a Related Entity acquiring another entity, an interest in
  another entity or an additional interest in a Related Entity whether by
  merger, stock purchase, asset purchase or other form of transaction.

     (e) Deferral of Award Payment. The Administrator may establish one or
  more programs under the Plan to permit selected Grantees the opportunity to
  elect to defer receipt of consideration upon exercise of an Award,
  satisfaction of performance criteria, or other event that absent the
  election would entitle the Grantee to payment or receipt of Shares or other
  consideration under an Award. The Administrator may establish the election
  procedures, the timing of such elections, the mechanisms for payments of,
  and accrual of interest or other earnings, if any, on amounts, Shares or
  other consideration so deferred, and such other terms, conditions, rules
  and procedures that the Administrator deems advisable for the
  administration of any such deferral program.

     (f) Award Exchange Programs. The Administrator may establish one or more
  programs under the Plan to permit selected Grantees to exchange an Award
  under the Plan for one or more other types of Awards under the Plan on such
  terms and conditions as determined by the Administrator from time to time.

     (g) Separate Programs. The Administrator may establish one or more
  separate programs under the Plan for the purpose of issuing particular
  forms of Awards to one or more classes of Grantees on such terms and
  conditions as determined by the Administrator from time to time.

     (h) Individual Option and SAR Limit. The maximum number of Shares with
  respect to which Options and SARs may be granted to any Grantee in any
  fiscal year of the Company shall be five hundred thousand (500,000) Shares.
  In connection with a Grantee's commencement of Continuous Service, a
  Grantee may be granted Options and SARs for up to an additional five
  hundred thousand (500,000) Shares which shall not count against the limit
  set forth in the previous sentence. The foregoing limitations shall be
  adjusted proportionately in connection with any change in the Company's
  capitalization pursuant to Section 11(a), below. To the extent required by
  Section 162(m) of the Code or the regulations thereunder, in applying the
  foregoing limitations with respect to a Grantee, if any Option or SAR is
  canceled, the canceled Option or SAR shall continue to count against the
  maximum number of Shares with respect to which Options and SARs may be
  granted to the Grantee. For this purpose, the repricing of an Option (or in
  the case of a SAR, the base amount on which the stock appreciation is
  calculated is reduced to reflect a reduction in the Fair Market Value of
  the Common Stock) shall be treated as the cancellation of the existing
  Option or SAR and the grant of a new Option or SAR.

     (i) Early Exercise. The Award Agreement may, but need not, include a
  provision whereby the Grantee may elect at any time while an Employee,
  Director or Consultant to exercise any part or all of the Award prior to
  full vesting of the Award. Any unvested Shares received pursuant to such
  exercise may be subject to a repurchase right in favor of the Company or a
  Related Entity or to any other restriction the Administrator determines to
  be appropriate.

     (j) Term of Award. The term of each Award shall be the term stated in
  the Award Agreement, provided, however, that the term shall be no more than
  ten (10) years from the date of grant thereof. However, in the case of an
  Incentive Stock Option granted to a Grantee who, at the time the Option is
  granted, owns stock representing more than ten percent (10%) of the voting
  power of all classes of stock of the Company or any Parent or Subsidiary,
  the term of the Incentive Stock Option shall be five (5) years from the
  date of grant thereof or such shorter term as may be provided in the Award
  Agreement.

     (k) Transferability of Awards. Incentive Stock Options may not be sold,
  pledged, assigned, hypothecated, transferred, or disposed of in any manner
  other than by will or by the laws of descent or distribution and may be
  exercised, during the lifetime of the Grantee, only by the Grantee;
  provided, however, that the Grantee may designate a beneficiary of the
  Grantee's Incentive Stock Option in the event

                                      B-6
<PAGE>

  of the Grantee's death on a beneficiary designation form provided by the
  Administrator. Other Awards may be transferred by gift or through a
  domestic relations order to members of the Grantee's Immediate Family to
  the extent provided in the Award Agreement or in the manner and to the
  extent determined by the Administrator.

     (l) Time of Granting Awards. The date of grant of an Award shall for all
  purposes be the date on which the Administrator makes the determination to
  grant such Award, or such other date as is determined by the Administrator.
  Notice of the grant determination shall be given to each Employee, Director
  or Consultant to whom an Award is so granted within a reasonable time after
  the date of such grant.

   7. Award Exercise or Purchase Price, Consideration, Taxes and Reload
Options.

     (a) Exercise or Purchase Price. The exercise or purchase price, if any,
  for an Award shall be as follows:

       (i) In the case of an Incentive Stock Option:

      Incentive Stock Option owns stock representing more than ten percent
      (10%) of the voting power of all classes of stock of the Company or
      any Parent or Subsidiary, the per Share exercise price shall be not
      less than one hundred ten percent (110%) of the Fair Market Value
      per Share on the date of grant; or

         (B) granted to any Employee other than an Employee described in
      the preceding paragraph, the per Share exercise price shall be not
      less than one hundred percent (100%) of the Fair Market Value per
      Share on the date of grant.

       (ii) In the case of a Non-Qualified Stock Option:

         (A) granted to a person who, at the time of the grant of such
      Option, owns stock representing more than ten percent (10%) of the
      voting power of all classes of stock of the Company or any Parent or
      Subsidiary, the per Share exercise price shall be not less than one
      hundred ten percent (110%) of the Fair Market Value per Share on the
      date of grant; or

         (B) granted to any person other than a person described in the
      preceding paragraph, the per Share exercise price shall be not less
      than eighty-five percent (85%) of the Fair Market Value per Share on
      the date of grant.

       (iii) In the case of Awards intended to qualify as Performance-Based
    Compensation, the exercise or purchase price, if any, shall be not less
    than one hundred percent (100%) of the Fair Market Value per Share on
    the date of grant.

       (iv) In the case of the sale of Shares:

         (A) granted to a person who, at the time of the grant of such
      Award, or at the time the purchase is consummated, owns stock
      representing more than ten percent (10%) of the voting power of all
      classes of stock of the Company or any Parent or Subsidiary, the per
      Share purchase price shall be not less than one hundred percent
      (100%) of the Fair Market Value per Share on the date of grant; or

         (B) granted to any person other than a person described in the
      preceding paragraph, the per Share purchase price shall be not less
      than eighty-five percent (85%) of the Fair Market Value per Share on
      the date of grant.

       (v) In the case of other Awards, such price as is determined by the
    Administrator.

       (vi) Notwithstanding the foregoing provisions of this Section 7(a),
    in the case of an Award issued pursuant to Section 6(d), above, the
    exercise or purchase price for the Award shall be determined in
    accordance with the principles of Section 424(a) of the Code.


                                      B-7
<PAGE>

     (b) Consideration. Subject to Applicable Laws, the consideration to be
  paid for the Shares to be issued upon exercise or purchase of an Award
  including the method of payment, shall be determined by the Administrator
  (and, in the case of an Incentive Stock Option, shall be determined at the
  time of grant). In addition to any other types of consideration the
  Administrator may determine, the Administrator is authorized to accept as
  consideration for Shares issued under the Plan the following:

       (i) cash;

       (ii) check;

       (iii) delivery of Grantee's promissory note with such recourse,
    interest, security, and redemption provisions as the Administrator
    determines as appropriate ;

       (iv) if the exercise or purchase occurs on or after the Registration
    Date, surrender of Shares or delivery of a properly executed form of
    attestation of ownership of Shares as the Administrator may require
    (including withholding of Shares otherwise deliverable upon exercise of
    the Award) which have a Fair Market Value on the date of surrender or
    attestation equal to the aggregate exercise price of the Shares as to
    which said Award shall be exercised (but only to the extent that such
    exercise of the Award would not result in an accounting compensation
    charge with respect to the Shares used to pay the exercise price unless
    otherwise determined by the Administrator);

       (v) with respect to Options, if the exercise occurs on or after the
    Registration Date, payment through a broker-dealer sale and remittance
    procedure pursuant to which the Grantee (A) shall provide written
    instructions to a Company designated brokerage firm to effect the
    immediate sale of some or all of the purchased Shares and remit to the
    Company, out of the sale proceeds available on the settlement date,
    sufficient funds to cover the aggregate exercise price payable for the
    purchased Shares and (B) shall provide written directives to the
    Company to deliver the certificates for the purchased Shares directly
    to such brokerage firm in order to complete the sale transaction; or

       (vi) any combination of the foregoing methods of payment.

     (c) Taxes. No Shares shall be delivered under the Plan to any Grantee or
  other person until such Grantee or other person has made arrangements
  acceptable to the Administrator for the satisfaction of any foreign,
  federal, state, or local income and employment tax withholding obligations,
  including, without limitation, obligations incident to the receipt of
  Shares or the disqualifying disposition of Shares received on exercise of
  an Incentive Stock Option. Upon exercise of an Award the Company shall
  withhold or collect from Grantee an amount sufficient to satisfy such tax
  obligations.

     (d) Reload Options. In the event the exercise price or tax withholding
  of an Option is satisfied by the Company or the Grantee's employer
  withholding Shares otherwise deliverable to the Grantee, the Administrator
  may issue the Grantee an additional Option, with terms identical to the
  Award Agreement under which the Option was exercised, but at an exercise
  price as determined by the Administrator in accordance with the Plan.

   8. Exercise of Award.

     (a) Procedure for Exercise; Rights as a Shareholder.

       (i) Any Award granted hereunder shall be exercisable at such times
    and under such conditions as determined by the Administrator under the
    terms of the Plan and specified in the Award Agreement but in the case
    of an Option, in no case at a rate of less than twenty percent (20%)
    per year over five (5) years from the date the Option is granted,
    subject to reasonable conditions such as continued employment.
    Notwithstanding the foregoing, in the case of an Option granted to an
    Officer, Director or Consultant, the Award Agreement may provide that
    the Option may become exercisable, subject to reasonable conditions
    such as such Officer's, Director's or Consultant's Continuous Service,
    at any time or during any period established in the Award Agreement.

       (ii) An Award shall be deemed to be exercised when written notice of
    such exercise has been given to the Company in accordance with the
    terms of the Award by the person entitled to exercise

                                      B-8
<PAGE>

    the Award and full payment for the Shares with respect to which the
    Award is exercised, including, to the extent selected, use of the
    broker-dealer sale and remittance procedure to pay the purchase price
    as provided in Section 7(b)(v). Until the issuance (as evidenced by the
    appropriate entry on the books of the Company or of a duly authorized
    transfer agent of the Company) of the stock certificate evidencing such
    Shares, no right to vote or receive dividends or any other rights as a
    shareholder shall exist with respect to Shares subject to an Award,
    notwithstanding the exercise of an Option or other Award. No adjustment
    will be made for a dividend or other right for which the record date is
    prior to the date the stock certificate is issued, except as provided
    in the Award Agreement or Section 11(a), below.

     (b) Exercise of Award Following Termination of Continuous Service. In
  the event of termination of a Grantee's Continuous Service for any reason
  other than Disability or death (but not in the event of a Grantee's change
  of status from Employee to Consultant or from Consultant to Employee), such
  Grantee may, but only during the Post-Termination Exercise Period (but in
  no event later than the expiration date of the term of such Award as set
  forth in the Award Agreement), exercise the Award to the extent that the
  Grantee was entitled to exercise it at the date of such termination or to
  such other extent as may be determined by the Administrator. The Grantee's
  Award Agreement may provide that upon the termination of the Grantee's
  Continuous Service for Cause, the Grantee's right to exercise the Award
  shall terminate concurrently with the termination of Grantee's Continuous
  Service. In the event of a Grantee's change of status from Employee to
  Consultant, an Employee's Incentive Stock Option shall convert
  automatically to a Non-Qualified Stock Option on the day three (3) months
  and one day following such change of status. To the extent that the Grantee
  is not entitled to exercise the Award at the date of termination, or if the
  Grantee does not exercise such Award to the extent so entitled within the
  Post-Termination Exercise Period, the Award shall terminate.

     (c) Disability of Grantee. In the event of termination of a Grantee's
  Continuous Service as a result of his or her Disability, Grantee may, but
  only within at least twelve (12) months from the date of such termination
  (and in no event later than the expiration date of the term of such Award
  as set forth in the Award Agreement), exercise the Award to the extent that
  the Grantee was otherwise entitled to exercise it at the date of such
  termination; provided, however, that if such Disability is not a
  "disability" as such term is defined in Section 22(e)(3) of the Code, in
  the case of an Incentive Stock Option such Incentive Stock Option shall
  automatically convert to a Non-Qualified Stock Option on the day three (3)
  months and one day following such termination. To the extent that the
  Grantee is not entitled to exercise the Award at the date of termination,
  or if Grantee does not exercise such Award to the extent so entitled within
  the time specified herein, the Award shall terminate.

     (d) Death of Grantee. In the event of a termination of the Grantee's
  Continuous Service as a result of his or her death, or in the event of the
  death of the Grantee during the Post-Termination Exercise Period, the
  Grantee's estate or a person who acquired the right to exercise the Award
  by bequest or inheritance may exercise the Award, but only to the extent
  that the Grantee was entitled to exercise the Award as of the date of
  termination, within at least twelve (12) months from the date of such
  termination (but in no event later than the expiration of the term of such
  Award as set forth in the Award Agreement). To the extent that, at the time
  of death, the Grantee was not entitled to exercise the Award, or if the
  Grantee's estate or a person who acquired the right to exercise the Award
  by bequest or inheritance does not exercise such Award to the extent so
  entitled within the time specified herein, the Award shall terminate.

     (e) Buyout Provisions. The Administrator may at any time offer to buy
  out for a payment in cash or Shares, an Award previously granted, based on
  such terms and conditions as the Administrator shall establish and
  communicate to the Grantee at the time that such offer is made.

   9. Conditions Upon Issuance of Shares.

     (a) Shares shall not be issued pursuant to the exercise of an Award
  unless the exercise of such Award and the issuance and delivery of such
  Shares pursuant thereto shall comply with all Applicable Laws, and shall be
  further subject to the approval of counsel for the Company with respect to
  such compliance.


                                      B-9
<PAGE>

     (b) As a condition to the exercise of an Award, the Company may require
  the person exercising such Award to represent and warrant at the time of
  any such exercise that the Shares are being purchased only for investment
  and without any present intention to sell or distribute such Shares if, in
  the opinion of counsel for the Company, such a representation is required
  by any Applicable Laws.

   10. Repurchase Rights. If the provisions of an Award Agreement grant to the
Company the right to repurchase Shares upon termination of the Grantee's
Continuous Service, the Award Agreement shall (or may, with respect to Awards
granted or issued to Officers, Directors or Consultants) provide that:

     (a) the right to repurchase must be exercised, if at all, within ninety
  (90) days of the termination of the Grantee's Continuous Service (or in the
  case of Shares issued upon exercise of Awards after the date of termination
  of the Grantee's Continuous Service, within ninety (90) days after the date
  of the Award exercise);

     (b) the consideration payable for the Shares upon exercise of such
  repurchase right shall be made in cash or by cancellation of purchase money
  indebtedness within the ninety (90) day periods specified in Section 10(a);

     (c) the amount of such consideration shall (i) be equal to the original
  purchase price paid by Grantee for each such Share; provided, that the
  right to repurchase such Shares at the original purchase price shall lapse
  at the rate of at least twenty percent (20%) of the Shares subject to the
  Award per year over five (5) years from the date the Award is granted
  (without respect to the date the Award was exercised or became
  exercisable), and (ii) with respect to Shares, other than Shares subject to
  repurchase at the original purchase price pursuant to clause (i) above, not
  less than the Fair Market Value of the Shares to be repurchased on the date
  of termination of Grantee's Continuous Service; and

     (d) the right to repurchase Shares, other than the right to repurchase
  Shares at the original purchase price pursuant to clause (i) of Section
  10(c), shall terminate on the Registration Date.

   11. Adjustments Upon Changes in Capitalization or Corporate Transaction.

     (a) Adjustments upon Changes in Capitalization. Subject to any required
  action by the shareholders of the Company, the number of Shares covered by
  each outstanding Award, and the number of Shares which have been authorized
  for issuance under the Plan but as to which no Awards have yet been granted
  or which have been returned to the Plan, the exercise or purchase price of
  each such outstanding Award, the maximum number of Shares with respect to
  which Options and SARs may be granted to any Grantee in any fiscal year of
  the Company, as well as any other terms that the Administrator determines
  require adjustment shall be proportionately adjusted for (i) any increase
  or decrease in the number of issued Shares resulting from a stock split,
  reverse stock split, stock dividend, combination or reclassification of the
  Shares, (ii) any other increase or decrease in the number of issued Shares
  effected without receipt of consideration by the Company, or (iii) as the
  Administrator may determine in its discretion, any other transaction with
  respect to Common Stock to which Section 424(a) of the Code applies;
  provided, however that conversion of any convertible securities of the
  Company shall not be deemed to have been "effected without receipt of
  consideration." Such adjustment shall be made by the Administrator and its
  determination shall be final, binding and conclusive. Except as the
  Administrator determines, no issuance by the Company of shares of stock of
  any class, or securities convertible into shares of stock of any class,
  shall affect, and no adjustment by reason hereof shall be made with respect
  to, the number or price of Shares subject to an Award.

     (b) Corporate Transaction. In the event of a Corporate Transaction each
  Award held by the Company's Chief Executive Officer, Chief Financial
  Officer and Executive Vice President of Technology and Network Operations
  which is at the time outstanding under the Plan shall automatically become
  fully vested and exercisable and be released from any restrictions on
  transfer (other than transfer restrictions applicable to Options)
  repurchase or forfeiture rights, immediately prior to the specified
  effective date of such Corporate Transaction, for all of the Shares at the
  time represented by such Awards. Effective upon the consummation of the
  Corporate Transaction, all such Awards under the Plan shall terminate

                                      B-10
<PAGE>

  immediately prior to the specified effective date of the Corporate
  Transaction unless the Award is assumed by the successor corporation or
  Parent thereof in connection with the Corporate Transaction. Except as
  provided otherwise in an individual Award Agreement, in the event of a
  Corporate Transaction, all other Awards under the Plan will terminate
  immediately prior to the specified effective date of the Corporate
  Transaction, unless the Award is assumed by the successor corporation or
  Parent thereof in connection with the Corporate Transaction.

   12. Effective Date and Term of Plan. The Plan shall become effective upon
the earlier to occur of its adoption by the Board or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated. Subject to Section 16, below, and Applicable
Laws, Awards may be granted under the Plan upon its becoming effective.

   13. Amendment, Suspension or Termination of the Plan.

     (a) The Board may at any time amend, suspend or terminate the Plan. To
  the extent necessary to comply with Applicable Laws, the Company shall
  obtain shareholder approval of any Plan amendment in such a manner and to
  such a degree as required.

     (b) No Award may be granted during any suspension of the Plan or after
  termination of the Plan.

     (c) Any amendment, suspension or termination of the Plan (including
  termination of the Plan under Section 12, above) shall not affect Awards
  already granted, and such Awards shall remain in full force and effect as
  if the Plan had not been amended, suspended or terminated, unless mutually
  agreed otherwise between the Grantee and the Administrator, which agreement
  must be in writing and signed by the Grantee and the Company.

   14. Reservation of Shares.

     (a) The Company, during the term of the Plan, will at all times reserve
  and keep available such number of Shares as shall be sufficient to satisfy
  the requirements of the Plan.

     (b) The inability of the Company to obtain authority from any regulatory
  body having jurisdiction, which authority is deemed by the Company's
  counsel to be necessary to the lawful issuance and sale of any Shares
  hereunder, shall relieve the Company of any liability in respect of the
  failure to issue or sell such Shares as to which such requisite authority
  shall not have been obtained.

   15. No Effect on Terms of Employment/Consulting Relationship. The Plan shall
not confer upon any Grantee any right with respect to the Grantee's Continuous
Service, nor shall it interfere in any way with his or her right or the
Company's right to terminate the Grantee's Continuous Service at any time, with
or without cause.

   16. No Effect on Retirement and Other Benefit Plans. Except as specifically
provided in a retirement or other benefit plan of the Company or a Related
Entity, Awards shall not be deemed compensation for purposes of computing
benefits or contributions under any retirement plan of the Company or a Related
Entity, and shall not affect any benefits under any other benefit plan of any
kind or any benefit plan subsequently instituted under which the availability
or amount of benefits is related to level of compensation. The Plan is not a
"Retirement-Plan" or "Welfare Plan" under the Employee Retirement Income
Security Act of 1974, as amended.

   17. Board and Shareholder Approval. The Plan was adopted by the Board during
January of 1999. On January 29, 1999, the Board adopted an amendment and
restatement of the Plan to revise the provisions of Section 11(b) relating to
the exercisability and termination of Awards under the Plan in the event of a
Corporate Transaction. On May 2, 2000, the Board adopted and approved an
amendment and restatement of the Plan (a) to increase the number of Shares
available for issuance under the Plan and (b) to adopt a limit on the maximum

                                      B-11
<PAGE>

number of Shares with respect to which Options may be granted to any Grantee in
any fiscal year of the Company and certain other administrative provisions to
comply with the performance-based compensation exception to the deduction limit
of Section 162(m) of the Code, which amendments are subject to approval by the
stockholders of the Company.

   18. Information to Grantees. The Company shall provide to each Grantee,
during the period for which such Grantee has one or more Awards outstanding,
copies of financial statements at least annually.

    date, on the last date on which such prices were reported), in each
    case, as reported in The Wall Street Journal or such other source as the
    Administrator deems reliable; or

       (2) In the absence of an established market of the type described in

   3. Eligibility.

     (a) General. Any individual who is an Employee on a given Enrollment
  Date shall be eligible to participate in the Plan for the Offer Period
  commencing with such Enrollment Date.

     (b) Limitations on Grant and Accrual. Any provisions of the Plan to the
  contrary notwithstanding, no Employee shall be granted an option under the
  Plan (i) if, immediately after the grant, such Employee (taking into
  account stock owned by any other person whose stock would be attributed to
  such Employee pursuant to Section 424(d) of the Code) would own stock
  and/or hold outstanding options to purchase stock possessing five percent
  (5%) or more of the total combined voting power or value of all classes of
  stock of the Company or of any Parent or Subsidiary, or (ii) which permits
  the Employee's rights to purchase stock under all employee stock purchase
  plans of the Company and its Parents or Subsidiaries to accrue at a rate
  which exceeds Twenty-Five Thousand Dollars ($25,000) worth of stock
  (determined at the Fair Market Value of the shares at the time such option
  is granted) for each calendar year in which such option is outstanding at
  any time. The determination of the accrual of the right to purchase stock
  shall be made in accordance with Section 423(b)(8) of the Code and the
  regulations thereunder.

     (c) Other Limits on Eligibility. Notwithstanding Subsection (a), above,
  the following Employees shall not be eligible to participate in the Plan
  for any relevant Offer Period: (i) Employees whose customary employment is
  20 hours or less per week; (ii) Employees whose customary employment is for
  not more than 5 months in any calendar year; (iii) Employees who have been
  employed for fewer than 30 days; and (iv) Employees who are subject to
  rules or laws of a foreign jurisdiction that prohibit or make impractical
  the participation of such Employees in the Plan.

   4. Offer Periods.

     (a) The Plan shall be implemented through overlapping or consecutive
  Offer Periods until such time as (i) the maximum number of shares of Common
  Stock available for issuance under the Plan shall have been purchased or
  (ii) the Plan shall have been sooner terminated in accordance with Section
  19 hereof. The maximum duration of an Offer Period shall be six (6) months.
  Initially, the Plan shall be implemented through consecutive Offer Periods
  of six (6) months' duration commencing each January 1 and July 1 following
  the Effective Date (except that the initial Offer Period shall commence on
  the Effective Date and shall end on the date determined by the
  Administrator at the commencement of the initial Offer Period).

     (b) A Participant shall be granted a separate option for each Offer
  Period in which he or she participates. The option shall be granted on the
  Enrollment Date and shall be automatically exercised on the last day of the
  Offer Period. However, with respect to any Offer Period, the Administrator
  may specify shorter Purchase Periods within an Offer Period, such that the
  option granted on the Enrollment Date shall be automatically exercised in
  successive installments on the last day of each Purchase Period ending
  within the Offer Period.

     (c) Except as specifically provided herein, the acquisition of Common
  Stock through participation in the Plan for any Offer Period shall neither
  limit nor require the acquisition of Common Stock by a Participant in any
  subsequent Offer Period.

                                      C-3
<PAGE>

   5. Participation.

     (a) An eligible Employee may become a Participant in the Plan by
  completing a subscription agreement authorizing payroll deductions in the
  form of Exhibit A (or in such other form or procedure the Administrator
  determines for evidencing elections to participate) to this Plan and filing
  it with the designated payroll office of the Company at least ten (10)
  business days prior to the Enrollment Date for the Offer Period in which
  such participation will commence, unless a later time for filing the
  subscription agreement is set by the Administrator for all eligible
  Employees with respect to a given Offer Period.

     (b) Payroll deductions for a Participant shall commence with the first
  partial or full payroll period beginning on the Enrollment Date and shall
  end on the last complete payroll period during the Offer Period, unless
  sooner terminated by the Participant as provided in Section 10.

   6. Payroll Deductions.

     (a) At the time a Participant files a subscription agreement, the
  Participant shall elect to have payroll deductions made during the Offer
  Period in amounts between one percent (1%) and not exceeding ten percent
  (10%) of the Compensation which the Participant receives during the Offer
  Period.

     (b) All payroll deductions made for a Participant shall be credited to
  the Participant's account under the Plan and will be withheld in whole
  percentages only. A Participant may not make any additional payments into
  such account.

     (c) A Participant may discontinue participation in the Plan as provided
  in Section 10, or may increase or decrease the rate of payroll deductions
  during the Offer Period by completing and filing with the Company a change
  of status notice in the form of Exhibit B to this Plan authorizing an
  increase or decrease in the payroll deduction rate. Any increase or
  decrease in the rate of a Participant's payroll deductions shall be
  effective with the first full payroll period commencing ten (10) business
  days after the Company's receipt of the change of status notice unless the
  Company elects to process a given change in participation more quickly. A
  Participant's subscription agreement (as modified by any change of status
  notice) shall remain in effect for successive Offer Periods unless
  terminated as provided in Section 10. The Administrator shall be authorized
  to limit the number of payroll deduction rate changes during any Offer
  Period.

     (d) Notwithstanding the foregoing, to the extent necessary to comply
  with Section 423(b)(8) of the Code and Section 3(b) herein, a Participant's
  payroll deductions shall be decreased to 0%. Payroll deductions shall
  recommence at the rate provided in such Participant's subscription
  agreement, as amended, at the time when permitted under Section 423(b)(8)
  of the Code and Section 3(b) herein, unless such participation is sooner
  terminated by the Participant as provided in Section 10.

   7. Grant of Option. On the Enrollment Date, each Participant shall be
granted an option to purchase (at the applicable Purchase Price) four hundred
(400) shares of the Common Stock, subject to adjustment as provided in Section
18 hereof; provided that such option shall be subject to the limitations set
forth in Sections 3(b), 6 and 12 hereof. Exercise of the option shall occur as
provided in Section 8, unless the Participant has withdrawn pursuant to Section
10, and the option, to the extent not exercised, shall expire on the last day
of the Offer Period.

   8. Exercise of Option. Unless a Participant withdraws from the Plan as
provided in Section 10, below, the Participant's option for the purchase of
shares will be exercised automatically on each Exercise Date, by applying the
accumulated payroll deductions in the Participant's account to purchase the
number of full shares subject to the option by dividing such Participant's
payroll deductions accumulated prior to such Exercise Date and retained in the
Participant's account as of the Exercise Date by the applicable Purchase Price.
No fractional shares will be purchased; any payroll deductions accumulated in a
Participant's account which are not sufficient to purchase a full share shall
be carried over to the next Offer Period or returned to the Participant, if the
Participant withdraws from the Plan. Notwithstanding the foregoing, any amount
remaining in a Participant's account following the purchase of shares on the
Exercise Date due to the application of Section 423(b)(8) of

                                      C-4
<PAGE>

the Code or Section 7, above, shall be returned to the Participant and shall
not be carried over to the next Offer Period. During a Participant's lifetime,
a Participant's option to purchase shares hereunder is exercisable only by the
Participant.

   9. Delivery. Upon receipt of a request from a Participant after each
Exercise Date on which a purchase of shares occurs, the Company shall arrange
the delivery to such Participant, as promptly as practicable, of a certificate
representing the shares purchased upon exercise of the Participant's option.

   10. Withdrawal; Termination of Employment.

     (a) A Participant may either (i) withdraw all but not less than all the
  payroll deductions credited to the Participant's account and not yet used
  to exercise the Participant's option under the Plan or (ii) terminate
  future payroll deductions, but allow accumulated payroll deductions to be
  used to exercise the Participant's option under the Plan at any time by
  giving written notice to the Company in the form of Exhibit B to this Plan.
  If the Participant elects withdrawal alternative (i) described above, all
  of the Participant's payroll deductions credited to the Participant's
  account will be paid to such Participant as promptly as practicable after
  receipt of notice of withdrawal, such Participant's option for the Offer
  Period will be automatically terminated, and no further payroll deductions
  for the purchase of shares will be made during the Offer Period. If the
  Participant elects withdrawal alternative (ii) described above, no further
  payroll deductions for the purchase of shares will be made during the Offer
  Period, all of the Participant's payroll deductions credited to the
  Participant's account will be applied to the exercise of the Participant's
  option on the next Exercise Date, and after such Exercise Date, such
  Participant's option for the Offer Period will be automatically terminated.
  If a Participant withdraws from an Offer Period, payroll deductions will
  not resume at the beginning of the succeeding Offer Period unless the
  Participant delivers to the Company a new subscription agreement.

     (b) Upon termination of a Participant's employment relationship (as
  described in Section 2(k)) at a time more than three (3) months from the
  next scheduled Exercise Date, the payroll deductions credited to such
  Participant's account during the Offer Period but not yet used to exercise
  the option will be returned to such Participant or, in the case of his/her
  death, to the person or persons entitled thereto under Section 14, and such
  Participant's option will be automatically terminated. Upon termination of
  a Participant's employment relationship (as described in Section 2(k))
  within three (3) months of the next scheduled Exercise Date, the payroll
  deductions credited to such Participant's account during the Offer Period
  but not yet used to exercise the option will be applied to the purchase of
  Common Stock on the next Exercise Date, unless the Participant (or in the
  case of the Participant's death, the person or persons entitled to the
  Participant's account balance under Section 14) withdraws from the Plan by
  submitting a change of status notice in accordance with subsection (a) of
  this Section 10. In such a case, no further payroll deductions will be
  credited to the Participant's account following the Participant's
  termination of employment and the Participant's option under the Plan will
  be automatically terminated after the purchase of Common Stock on the next
  scheduled Exercise Date.

   11. Interest. No interest shall accrue on the payroll deductions credited to
a Participant's account under the Plan.

   12. Stock.

     (a) The maximum number of shares of Common Stock which shall be made
  available for sale under the Plan shall be 1,000,000 shares, subject to
  adjustment upon changes in capitalization of the Company as provided in
  Section 18. If the Administrator determines that on a given Exercise Date
  the number of shares with respect to which options are to be exercised may
  exceed (x) the number of shares then available for sale under the Plan or
  (y) the number of shares available for sale under the Plan on the
  Enrollment Date(s) of one or more of the Offer Periods in which such
  Exercise Date is to occur, the Administrator may make a pro rata allocation
  of the shares remaining available for purchase on such Enrollment Dates or
  Exercise Date, as applicable, in as uniform a manner as shall be
  practicable and as it

                                      C-5
<PAGE>

  shall determine to be equitable, and shall either continue all Offer
  Periods then in effect or terminate any one or more Offer Periods then in
  effect pursuant to Section 19, below.

     (b) A Participant will have no interest or voting right in shares
  covered by the Participant's option until such shares are actually
  purchased on the Participant's behalf in accordance with the applicable
  provisions of the Plan. No adjustment shall be made for dividends,
  distributions or other rights for which the record date is prior to the
  date of such purchase.

     (c) Shares to be delivered to a Participant under the Plan will be
  registered in the name of the Participant or in the name of the Participant
  and his or her spouse.

   13. Administration. The Plan shall be administered by the Administrator
which shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision
and determination made by the Administrator shall, to the full extent permitted
by Applicable Law, be final and binding upon all persons.

   14. Designation of Beneficiary.

     (a) Each Participant will file a written designation of a beneficiary
  who is to receive any shares and cash, if any, from the Participant's
  account under the Plan in the event of such Participant's death. If a
  Participant is married and the designated beneficiary is not the spouse,
  spousal consent shall be required for such designation to be effective.

     (b) Such designation of beneficiary may be changed by the Participant
  (and the Participant's spouse, if any) at any time by written notice. In
  the event of the death of a Participant and in the absence of a beneficiary
  validly designated under the Plan who is living (or in existence) at the
  time of such Participant's death, the Company shall deliver such shares
  and/or cash to the executor or administrator of the estate of the
  Participant, or if no such executor or administrator has been appointed (to
  the knowledge of the Administrator), the Administrator shall deliver such
  shares and/or cash to the spouse (or domestic partner, as determined by the
  Administrator) of the Participant, or if no spouse (or domestic partner) is
  known to the Administrator, then to the issue of the Participant, such
  distribution to be made per stirpes (by right of representation), or if no
  issue are known to the Administrator, then to the heirs at law of the
  Participant determined in accordance with Section 27.

   15. Transferability. Neither payroll deductions credited to a Participant's
account nor any rights with regard to the exercise of an option or to receive
shares under the Plan may be assigned, transferred, pledged or otherwise
disposed of in any way (other than by will, the laws of descent and
distribution, or as provided in Section 14 hereof) by the Participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Administrator may treat such act as an election to
withdraw funds from an Offer Period in accordance with Section 10.

   16. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

   17. Reports. Individual accounts will be maintained for each Participant in
the Plan. Statements of account will be given to Participants at least
annually, which statements will set forth the amounts of payroll deductions,
the Purchase Price, the number of shares purchased and the remaining cash
balance, if any.

   18. Adjustments Upon Changes in Capitalization; Corporate Transactions.

     (a) Adjustments Upon Changes in Capitalization. Subject to any required
  action by the stockholders of the Company, the Reserves, the Purchase
  Price, the maximum number of shares that may be purchased in any Offer
  Period or Purchase Period, as well as any other terms that the
  Administrator determines require adjustment shall be proportionately
  adjusted for (i) any increase or decrease in the number of issued shares of
  Common Stock resulting from a stock split, reverse stock split, stock
  dividend, combination or reclassification of the Common Stock, (ii) any
  other increase or decrease in the number of

                                      C-6
<PAGE>

  issued shares of Common Stock effected without receipt of consideration by
  the Company, or (iii) as the Administrator may determine in its discretion,
  any other transaction with respect to Common Stock to which Section 424(a)
  of the Code applies; provided, however that conversion of any convertible
  securities of the Company shall not be deemed to have been "effected
  without receipt of consideration." Such adjustment shall be made by the
  Administrator and its determination shall be final, binding and conclusive.
  Except as the Administrator determines, no issuance by the Company of
  shares of stock of any class, or securities convertible into shares of
  stock of any class, shall affect, and no adjustment by reason hereof shall
  be made with respect to, the Reserves and the Purchase Price.

     (b) Corporate Transactions. In the event of a proposed Corporate
  Transaction, each option under the Plan shall be assumed by such successor
  corporation or a parent or subsidiary of such successor corporation, unless
  the Administrator determines, in the exercise of its sole discretion and in
  lieu of such assumption, to shorten the Offer Period then in progress by
  setting a new Exercise Date (the "New Exercise Date"). If the Administrator
  shortens the Offer Period then in progress in lieu of assumption in the
  event of a Corporate Transaction, the Administrator shall notify each
  Participant in writing, at least ten (10) days prior to the New Exercise
  Date, that the Exercise Date for the Participant's option has been changed
  to the New Exercise Date and that the Participant's option will be
  exercised automatically on the New Exercise Date, unless prior to such date
  the Participant has withdrawn from the Offer Period as provided in Section
  10. For purposes of this Subsection, an option granted under the Plan shall
  be deemed to be assumed if, in connection with the Corporate Transaction,
  the option is replaced with a comparable option with respect to shares of
  capital stock of the successor corporation or Parent thereof. The
  determination of option comparability shall be made by the Administrator
  prior to the Corporate Transaction and its determination shall be final,
  binding and conclusive on all persons.

   19. Amendment or Termination.

     (a) The Administrator may at any time and for any reason terminate or
  amend the Plan. Except as provided in Section 18, no such termination can
  affect options previously granted, provided that the Plan or any one or
  more Offer Periods may be terminated by the Administrator on any Exercise
  Date or by the Administrator establishing a new Exercise Date with respect
  to any Offer Period and/or any Purchase Period then in progress if the
  Administrator determines that the termination of the Plan or such one or
  more Offer Periods is in the best interests of the Company and its
  stockholders. Except as provided in Section 18 and this Section 19, no
  amendment may make any change in any option theretofore granted which
  adversely affects the rights of any Participant without the consent of
  affected Participants. To the extent necessary to comply with Section 423
  of the Code (or any successor rule or provision or any other Applicable
  Law), the Company shall obtain stockholder approval in such a manner and to
  such a degree as required.

     (b) Without stockholder consent and without regard to whether any
  Participant rights may be considered to have been "adversely affected," the
  Administrator shall be entitled to limit the frequency and/or number of
  changes in the amount withheld during Offer Periods, change the length of
  Purchase Periods within any Offer Period, determine the length of any
  future Offer Period, determine whether future Offer Periods shall be
  consecutive or overlapping, establish the exchange ratio applicable to
  amounts withheld in a currency other than U.S. dollars, establish
  additional terms, conditions, rules or procedures to accommodate the rules
  or laws of applicable foreign jurisdictions, permit payroll withholding in
  excess of the amount designated by a Participant in order to adjust for
  delays or mistakes in the Company's processing of properly completed
  withholding elections, establish reasonable waiting and adjustment periods
  and/or accounting and crediting procedures to ensure that amounts applied
  toward the purchase of Common Stock for each Participant properly
  correspond with amounts withheld from the Participant's Compensation, and
  establish such other limitations or procedures as the Administrator
  determines in its sole discretion advisable and which are consistent with
  the Plan.

   20. Notices. All notices or other communications by a Participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Administrator at the location,
or by the person, designated by the Administrator for the receipt thereof.

                                      C-7

   21. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all Applicable Laws
and shall be further subject to the approval of counsel for the Company with
respect to such compliance. As a condition to the exercise of an option, the
Company may require the Participant to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned Applicable Laws. In addition, no options shall be exercised
or shares issued hereunder before the Plan shall have been approved by
stockholders of the Company as provided in Section 23.

   22. Term of Plan. The Plan shall become effective upon the earlier to occur
of its adoption by the Board or its approval by the stockholders of the
Company. It shall continue in effect for a term of twenty (20) years unless
sooner terminated under Section 19.

   23. Stockholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such stockholder approval shall be obtained
in the degree and manner required under Applicable Laws.

   24. No Employment Rights. The Plan does not, directly or indirectly, create
any right for the benefit of any employee or class of employees to purchase any
shares under the Plan, or create in any employee or class of employees any
right with respect to continuation of employment by the Company or a Designated
Parent or Subsidiary, and it shall not be deemed to interfere in any way with
such employer's right to terminate, or otherwise modify, an employee's
employment at any time.

   25. No Effect on Retirement and Other Benefit Plans. Except as specifically
provided in a retirement or other benefit plan of the Company or a Designated
Parent or Subsidiary, participation in the Plan shall not be deemed
compensation for purposes of computing benefits or contributions under any
retirement plan of the Company or a Designated Parent or Subsidiary, and shall
not affect any benefits under any other benefit plan of any kind or any benefit
plan subsequently instituted under which the availability or amount of benefits
is related to level of compensation. The Plan is not a "Retirement Plan" or
"Welfare Plan" under the Employee Retirement Income Security Act of 1974, as
amended.

   26. Effect of Plan. The provisions of the Plan shall, in accordance with its
terms, be binding upon, and inure to the benefit of, all successors of each
Participant, including, without limitation, such Participant's estate and the
executors, administrators or trustees thereof, heirs and legatees, and any
receiver, trustee in bankruptcy or representative of creditors of such
Participant.

   27. Governing Law. The Plan is to be construed in accordance with and
governed by the internal laws of the State of California (as permitted by
Section 1646.5 of the California Civil Code, or any similar successor
provision) without giving effect to any choice of law rule that would cause the
application of the laws of any jurisdiction other than the internal laws of the
State of California to the rights and duties of the parties, except to the
extent the internal laws of the State of California are superseded by the laws
of the United States. Should any provision of the Plan be determined by a court
of law to be illegal or unenforceable, the other provisions shall nevertheless
remain effective and shall remain enforceable.

   28. Dispute Resolution. The provisions of this Section 28 (and as restated
in the Subscription Agreement) shall be the exclusive means of resolving
disputes arising out of or relating to the Plan. The Company and the
Participant, or their respective successors (the "parties"), shall attempt in
good faith to resolve any disputes arising out of or relating to the Plan by
negotiation between individuals who have authority to settle the controversy.
Negotiations shall be commenced by either party by notice of a written
statement of the party's position and the name and title of the individual who
will represent the party. Within thirty (30) days of the written notification,
the parties shall meet at a mutually acceptable time and place, and thereafter
as often as they reasonably deem necessary, to resolve the dispute. If the
dispute has not been resolved by negotiation, the

                                      C-8
<PAGE>

parties agree that any suit, action, or proceeding arising out of or relating
to the Plan shall be brought in the United States District Court for the
Northern District of California (or should such court lack jurisdiction to hear
such action, suit or proceeding, in a California state court in the County of
San Francisco) and that the parties shall submit to the jurisdiction of such
court. The parties irrevocably waive, to the fullest extent permitted by law,

   the meaning set forth in the ESPP.

4. Subscription I hereby elect to participate in the ESPP and subscribe to
   purchase shares of the Company's Common Stock in accordance with this
   Subscription Agreement and the ESPP. I have received a complete copy of the
   ESPP and a prospectus describing the ESPP and understand that my
   participation in the ESPP is in all respects subject to the terms of the
   ESPP. The effectiveness of this Subscription Agreement is dependent on my
   eligibility to participate in the ESPP.

5. Payroll Deduction Authorization I hereby authorize payroll deductions from
   my Compensation during the Offer Period in the percentage specified below
   (payroll reductions may not exceed 10% of Compensation nor $21,250 per
   calendar year):


<TABLE>
    <S>                                <C> <C> <C> <C> <C> <C> <C> <C> <C> <C>

</TABLE>


6. ESPP Accounts and Purchase Price I understand that all payroll deductions
   will be credited to my account under the ESPP. No additional payments may be
   made to my account. No interest will be credited on funds held in the
   account at any time including any refund of the account caused by withdrawal
   from the ESPP. All payroll deductions shall be accumulated for the purchase
   of Company Common Stock at the applicable Purchase Price determined in
   accordance with the ESPP.

7. Withdrawal and Changes in Payroll Deduction I understand that I may
   discontinue my participation in the ESPP at any time prior to an Exercise
   Date as provided in Section 10 of the ESPP, but if I do not

                                      C-10
<PAGE>

   withdraw from the ESPP, any accumulated payroll deductions will be applied
   automatically to purchase Company Common Stock. I may increase or decrease
   the rate of my payroll deductions in whole percentage increments to not
   less than one percent (1%) on (one) occasion(s) during any Purchase Period
   by completing and timely filing a Change of Status Notice. Any increase or
   decrease will be effective for the full payroll period occurring after ten
   (10) business days from the Company's receipt of the Change of Status
   Notice.

8. Perpetual Subscription I understand that this Subscription Agreement shall
   remain in effect for successive Offer Periods until I withdraw from
   participation in the ESPP, or termination of the ESPP.

9. Taxes I have reviewed the ESPP prospectus discussion of the federal tax
   consequences of participation in the ESPP and consulted with tax
   consultants as I deemed advisable prior to my participation in the ESPP. I
   hereby agree to notify the Company in writing within thirty (30) days of
   any disposition (transfer or sale) of any shares purchased under the ESPP
   if such disposition occurs within two (2) years of the Enrollment Date (the
   first day of the Offer Period during which the shares were purchased) or
   within one (1) year of the Exercise Date (the date I purchased such
   shares), and I will make adequate provision to the Company for foreign,
   federal, state or other tax withholding obligations, if any, which arise
   upon the disposition of the shares. In addition, the Company may withhold
   from my Compensation any amount necessary to meet applicable tax
   withholding obligations incident to my participation in the ESPP, including
   any withholding necessary to make available to the Company any tax
   deductions or benefits contingent on such withholding.

10. Dispute Resolution The provisions of this Section 10 and Section 28 of the
    ESPP shall be the exclusive means of resolving disputes arising out of or
    relating to the Plan. The Company and I, or our respective successors (the
    "parties"), shall attempt in good faith to resolve any disputes arising
    out of or relating to the Plan by negotiation between individuals who have
    authority to settle the controversy. Negotiations shall be commenced by
    either party by notice of a written statement of the party's position and
    the name and title of the individual who will represent the party. Within
    thirty (30) days of the written notification, the parties shall meet at a
    mutually acceptable time and place, and thereafter as often as they
    reasonably deem necessary, to resolve the dispute. If the dispute has not
    been resolved by negotiation, the Company and I agree that any suit,
    action, or proceeding arising out of or relating to the Plan shall be
    brought in the United States District Court for the Northern District of
    California (or should such court lack jurisdiction to hear such action,
    suit or proceeding, in a California state court in the County of San
    Francisco) and that we shall submit to the jurisdiction of such court. The
    Company and I irrevocably waive, to the fullest extent permitted by law,
    any objection we may have to the laying of venue for any such suit, action
    or proceeding brought in such court. THE COMPANY AND I ALSO EXPRESSLY
    WAIVE ANY RIGHT WE HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT,
    ACTION OR PROCEEDING. If any one or more provisions of this Section 10 or
    Section 28 of the ESPP shall for any reason be held invalid or
    unenforceable, it is the specific intent of the Company and I that such
    provisions shall be modified to the minimum extent necessary to make it or
    its application valid and enforceable.

    the following person or trust as my beneficiary to receive all payments
    and shares due to me under the ESPP:  [_] I am single

    exercisable in its sole discretion, to amend or terminate the ESPP at any
    time, and a termination may be effective as early as an Exercise Date,
