                         Kendara, Inc. 1999 Stock Plan

SECTION 1.  ESTABLISHMENT AND PURPOSE.

     The purpose of the Plan is to offer selected individuals an opportunity to
acquire a proprietary interest in the success of the Company, or to increase
such interest, by purchasing Shares of the Company's Stock. The Plan provides
both for the direct award or sale of Shares and for the grant of Options to
purchase Shares. Options granted under the Plan may include Nonstatutory Options
as well as ISOs intended to qualify under Section 422 of the Code.

     Capitalized terms are defined in Section 12.

SECTION 2.  ADMINISTRATION.

     (a)  Committees of the Board of Directors. The Plan may be administered by
one or more Committees. Each Committee shall consist of one or more members of
the Board of Directors who have been appointed by the Board of Directors. Each
Committee shall have such authority and be responsible for such functions as the
Board of Directors has assigned to it. If no Committee has been appointed, the
entire Board of Directors shall administer the Plan. Any reference to the Board
of Directors in the Plan shall be construed as a reference to the Committee (if
any) to whom the Board of Directors has assigned a particular function.

     (b)  Authority of the Board of Directors. Subject to the provisions of the
Plan, the Board of Directors shall have full authority and discretion to take
any actions it deems necessary or advisable for the administration of the Plan.
All decisions, interpretations and other actions of the Board of Directors shall
be final and binding on all Purchasers, all Optionees and all persons deriving
their rights from a Purchaser or Optionee.

SECTION 3.  ELIGIBILITY.

     (a)  General Rule. Only Employees, Outside Directors and Consultants shall
be eligible for the grant of Options or the direct award or sale of Shares. Only
Employees shall be eligible for the grant of ISOs.

     (b)  Ten-Percent Stockholders. An individual who owns more than 10% of the
total combined voting power of all classes of outstanding stock of the Company,
its Parent or any of its Subsidiaries shall not be eligible for designation as
an Optionee or Purchaser unless (i) the Exercise Price is at least 110% of the
Fair Market Value of a Share on the date of grant, (ii) the Purchase Price (if
any) is at least 100% of the Fair Market Value of a Share and (iii) in the case
of an ISO, such ISO by its terms is not exercisable after the expiration of five
years from the date of grant. For purposes of this Subsection (b), in
determining stock ownership, the attribution rules of Section 424(d) of the Code
shall be applied.
<PAGE>

SECTION 4.  STOCK SUBJECT TO PLAN.

     (a)  Basic Limitation. Shares offered under the Plan may be authorized but
unissued Shares or treasury Shares. The aggregate number of Shares that may be
issued under the Plan (upon exercise of Options or other rights to acquire
Shares) shall not exceed 3,357,142/1/ Shares, subject to adjustment pursuant to
Section 8. The number of Shares that are subject to Options or other rights
outstanding at any time under the Plan shall not exceed the number of Shares
that then remain available for issuance under the Plan. The Company, during the
term of the Plan, shall at all times reserve and keep available sufficient
Shares to satisfy the requirements of the Plan.

     (b)  Additional Shares. In the event that any outstanding Option or other
right for any reason expires or is canceled or otherwise terminated, the Shares
allocable to the unexercised portion of such Option or other right shall again
be available for the purposes of the Plan. In the event that Shares issued under
the Plan are reacquired by the Company pursuant to any forfeiture provision,
right of repurchase or right of first refusal, such Shares shall again be
available for the purposes of the Plan, except that the aggregate number of
Shares which may be issued upon the exercise of ISOs shall in no event exceed
3,357,142 Shares (subject to adjustment pursuant to Section 8).

SECTION 5.  TERMS AND CONDITIONS OF AWARDS OR SALES.

     (a)  Stock Purchase Agreement. Each award or sale of Shares under the Plan
(other than upon exercise of an Option) shall be evidenced by a Stock Purchase
Agreement between the Purchaser and the Company. Such award or sale shall be
subject to all applicable terms and conditions of the Plan and may be subject to
any other terms and conditions which are not inconsistent with the Plan and
which the Board of Directors deems appropriate for inclusion in a Stock Purchase
Agreement. The provisions of the various Stock Purchase Agreements entered into
under the Plan need not be identical.

     (b)  Duration of Offers and Nontransferability of Rights. Any right to
acquire Shares under the Plan (other than an Option) shall automatically expire
if not exercised by the Purchaser within 30 days after the grant of such right
was communicated to the Purchaser by the Company. Such right shall not be
transferable and shall be exercisable only by the Purchaser to whom such right
was granted.

     (c)  Purchase Price. The Purchase Price of Shares to be offered under the
Plan shall not be less than 85% of the Fair Market Value of such Shares, and a
higher percentage may be required by Section 3(b). Subject to the preceding
sentence, the Purchase Price shall be determined by the Board of Directors at
its sole discretion. The Purchase Price shall be payable in a form described in
Section 7.

     (d)  Withholding Taxes. As a condition to the purchase of Shares, the
Purchaser shall make such arrangements as the Board of Directors may require for
the satisfaction of any

_______________________
/1/ Reflects stock split approved by the Board of Directors in May 1999 and a
500,000 share increase on February 1, 2000.

                                       2
<PAGE>

federal, state, local or foreign withholding tax obligations that may arise in
connection with such purchase.

     (e)  Restrictions on Transfer of Shares and Minimum Vesting. Any Shares
awarded or sold under the Plan shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer
restrictions as the Board of Directors may determine. Such restrictions shall be
set forth in the applicable Stock Purchase Agreement and shall apply in addition
to any restrictions that may apply to holders of Shares generally. In the case
of a Purchaser who is not an officer of the Company, an Outside Director or a
Consultant, any right to repurchase the Purchaser's Shares at the original
Purchase Price (if any) upon termination of the Purchaser's Service shall lapse
at least as rapidly as 20% per year over the five-year period commencing on the
date of the award or sale of the Shares. Any such right may be exercised only
within 90 days after the termination of the Purchaser's Service for cash or for
cancellation of indebtedness incurred in purchasing the Shares.

     (f)  Accelerated Vesting. Unless the applicable Stock Purchase Agreement
provides otherwise, any right to repurchase a Purchaser's Shares at the original
Purchase Price (if any) upon termination of the Purchaser's Service shall lapse
and all of such Shares shall become vested if (i) the Company is subject to a
Change in Control before the Purchaser's Service terminates and (ii) the
repurchase right is not assigned to the entity that employs the Purchaser
immediately after the Change in Control or to its parent or subsidiary.

SECTION 6.  TERMS AND CONDITIONS OF OPTIONS.

     (a)  Stock Option Agreement. Each grant of an Option under the Plan shall
be evidenced by a Stock Option Agreement between the Optionee and the Company.
Such Option shall be subject to all applicable terms and conditions of the Plan
and may be subject to any other terms and conditions which are not inconsistent
with the Plan and which the Board of Directors deems appropriate for inclusion
in a Stock Option Agreement. The provisions of the various Stock Option
Agreements entered into under the Plan need not be identical.

     (b)  Number of Shares. Each Stock Option Agreement shall specify the number
of Shares that are subject to the Option and shall provide for the adjustment of
such number in accordance with Section 8. The Stock Option Agreement shall also
specify whether the Option is an ISO or a Nonstatutory Option.

     (c)  Exercise Price. Each Stock Option Agreement shall specify the Exercise
Price. The Exercise Price of an ISO shall not be less than 100% of the Fair
Market Value of a Share on the date of grant, and a higher percentage may be
required by Section 3(b). The Exercise Price of a Nonstatutory Option shall not
be less than 85% of the Fair Market Value of a Share on the date of grant, and a
higher percentage may be required by Section 3(b). Subject to the preceding two
sentences, the Exercise Price under any Option shall be determined by the Board
of Directors at its sole discretion. The Exercise Price shall be payable in a
form described in Section 7.

     (d)  Withholding Taxes. As a condition to the exercise of an Option, the
Optionee shall make such arrangements as the Board of Directors may require for
the satisfaction of any

                                       3
<PAGE>

federal, state, local or foreign withholding tax obligations that may arise in
connection with such exercise. The Optionee shall also make such arrangements as
the Board of Directors may require for the satisfaction of any federal, state,
local or foreign withholding tax obligations that may arise in connection with
the disposition of Shares acquired by exercising an Option.

     (e)  Exercisability. Each Stock Option Agreement shall specify the date
when all or any installment of the Option is to become exercisable. In the case
of an Optionee who is not an officer of the Company, an Outside Director or a
Consultant, an Option shall become exercisable at least as rapidly as 20% per
year over the five-year period commencing on the date of grant. Subject to the
preceding sentence, the exercisability provisions of any Stock Option Agreement
shall be determined by the Board of Directors at its sole discretion.

     (f)  Accelerated Exercisability. Unless the applicable Stock Option
Agreement provides otherwise, all of an Optionee's Options shall become
exercisable in full if (i) the Company is subject to a Change in Control before
the Optionee's Service terminates, (ii) such Options do not remain outstanding,
(iii) such Options are not assumed by the surviving corporation or its parent
and (iv) the surviving corporation or its parent does not substitute options
with substantially the same terms for such Options.

     (g)  Basic Term. The Stock Option Agreement shall specify the term of the
Option. The term shall not exceed 10 years from the date of grant, and a shorter
term may be required by Section 3(b). Subject to the preceding sentence, the
Board of Directors at its sole discretion shall determine when an Option is to
expire.

     (h)  Nontransferability. No Option shall be transferable by the Optionee
other than by beneficiary designation, will or the laws of descent and
distribution. An Option may be exercised during the lifetime of the Optionee
only by the Optionee or by the Optionee's guardian or legal representative. No
Option or interest therein may be transferred, assigned, pledged or hypothecated
by the Optionee during the Optionee's lifetime, whether by operation of law or
otherwise, or be made subject to execution, attachment or similar process.

     (i)  Termination of Service (Except by Death). If an Optionee's Service
terminates for any reason other than the Optionee's death, then the Optionee's
Options shall expire on the earliest of the following occasions:

          (i)   The expiration date determined pursuant to Subsection (g) above;

          (ii)  The date three months after the termination of the Optionee's
     Service for any reason other than Disability, or such later date as the
     Board of Directors may determine; or

          (iii) The date six months after the termination of the Optionee's
     Service by reason of Disability, or such later date as the Board of
     Directors may determine.

The Optionee may exercise all or part of the Optionee's Options at any time
before the expiration of such Options under the preceding sentence, but only to
the extent that such Options had become exercisable before the Optionee's
Service terminated (or became exercisable as a result

                                       4
<PAGE>

of the termination) and the underlying Shares had vested before the Optionee's
Service terminated (or vested as a result of the termination). The balance of
such Options shall lapse when the Optionee's Service terminates. In the event
that the Optionee dies after the termination of the Optionee's Service but
before the expiration of the Optionee's Options, all or part of such Options may
be exercised (prior to expiration) by the executors or administrators of the
Optionee's estate or by any person who has acquired such Options directly from
the Optionee by beneficiary designation, bequest or inheritance, but only to the
extent that such Options had become exercisable before the Optionee's Service
terminated (or became exercisable as a result of the termination) and the
underlying Shares had vested before the Optionee's Service terminated (or vested
as a result of the termination).

     (j)  Leaves of Absence. For purposes of Subsection (i) above, Service shall
be deemed to continue while the Optionee is on a bona fide leave of absence, if
such leave was approved by the Company in writing and if continued crediting of
Service for this purpose is expressly required by the terms of such leave or by
applicable law (as determined by the Company).

     (k)  Death of Optionee. If an Optionee dies while the Optionee is in
Service, then the Optionee's Options shall expire on the earlier of the
following dates:

          (i)  The expiration date determined pursuant to Subsection (g) above;
     or

          (ii) The date 12 months after the Optionee's death.

All or part of the Optionee's Options may be exercised at any time before the
expiration of such Options under the preceding sentence by the executors or
administrators of the Optionee's estate or by any person who has acquired such
Options directly from the Optionee by beneficiary designation, bequest or
inheritance, but only to the extent that such Options had become exercisable
before the Optionee's death or became exercisable as a result of the death. The
balance of such Options shall lapse when the Optionee dies.

     (l)  No Rights as a Stockholder. An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by the Optionee's Option until such person becomes entitled to receive
such Shares by filing a notice of exercise and paying the Exercise Price
pursuant to the terms of such Option.

     (m)  Modification, Extension and Assumption of Options. Within the
limitations of the Plan, the Board of Directors may modify, extend or assume
outstanding Options or may accept the cancellation of outstanding Options
(whether granted by the Company or another issuer) in return for the grant of
new Options for the same or a different number of Shares and at the same or a
different Exercise Price. The foregoing notwithstanding, no modification of an
Option shall, without the consent of the Optionee, impair the Optionee's rights
or increase the Optionee's obligations under such Option.

     (n)  Restrictions on Transfer of Shares and Minimum Vesting. Any Shares
issued upon exercise of an Option shall be subject to such special forfeiture
conditions, rights of repurchase, rights of first refusal and other transfer
restrictions as the Board of Directors may

                                       5
<PAGE>

determine. Such restrictions shall be set forth in the applicable Stock Option
Agreement and shall apply in addition to any restrictions that may apply to
holders of Shares generally. In the case of an Optionee who is not an officer of
the Company, an Outside Director or a Consultant:

     (i)   Any right to repurchase the Optionee's Shares at the original
     Exercise Price upon termination of the Optionee's Service shall lapse at
     least as rapidly as 20% per year over the five-year period commencing on
     the date of the option grant;

     (ii)  Any such right may be exercised only for cash or for cancellation of
     indebtedness incurred in purchasing the Shares; and

     (iii) Any such right may be exercised only within 90 days after the later
     of (A) the termination of the Optionee's Service or (B) the date of the
     option exercise.

     (o)   Accelerated Vesting. Unless the applicable Stock Option Agreement
provides otherwise, any right to repurchase an Optionee's Shares at the original
Exercise Price upon termination of the Optionee's Service shall lapse and all of
such Shares shall become vested if (i) the Company is subject to a Change in
Control before the Optionee's Service terminates and (ii) the repurchase right
is not assigned to the entity that employs the Optionee immediately after the
Change in Control or to its parent or subsidiary.

SECTION 7.  PAYMENT FOR SHARES.

     (a)   General Rule. The entire Purchase Price or Exercise Price of Shares
issued under the Plan shall be payable in cash or cash equivalents at the time
when such Shares are purchased, except as otherwise provided in this Section 7.

     (b)   Surrender of Stock. To the extent that a Stock Option Agreement so
provides, all or any part of the Exercise Price may be paid by surrendering, or
attesting to the ownership of, Shares that are already owned by the Optionee.
Such Shares shall be surrendered to the Company in good form for transfer and
shall be valued at their Fair Market Value on the date when the Option is
exercised. The Optionee shall not surrender, or attest to the ownership of,
Shares in payment of the Exercise Price if such action would cause the Company
to recognize compensation expense (or additional compensation expense) with
respect to the Option for financial reporting purposes.

     (c)   Services Rendered. At the discretion of the Board of Directors,
Shares may be awarded under the Plan in consideration of services rendered to
the Company, a Parent or a Subsidiary prior to the award.

     (d)   Promissory Note. To the extent that a Stock Option Agreement or Stock
Purchase Agreement so provides, all or a portion of the Exercise Price or
Purchase Price (as the case may be) of Shares issued under the Plan may be paid
with a full-recourse promissory note. However, the par value of the Shares, if
newly issued, shall be paid in cash or cash equivalents. The Shares shall be
pledged as security for payment of the principal amount of the promissory

                                       6
<PAGE>

note and interest thereon. The interest rate payable under the terms of the
promissory note shall not be less than the minimum rate (if any) required to
avoid the imputation of additional interest under the Code. Subject to the
foregoing, the Board of Directors (at its sole discretion) shall specify the
term, interest rate, amortization requirements (if any) and other provisions of
such note.

     (e)  Exercise/Sale. To the extent that a Stock Option Agreement so
provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction
to a securities broker approved by the Company to sell Shares and to deliver all
or part of the sales proceeds to the Company in payment of all or part of the
Exercise Price and any withholding taxes.

     (f)  Exercise/Pledge. To the extent that a Stock Option Agreement so
provides, and if Stock is publicly traded, payment may be made all or in part by
the delivery (on a form prescribed by the Company) of an irrevocable direction
to pledge Shares to a securities broker or lender approved by the Company, as
security for a loan, and to deliver all or part of the loan proceeds to the
Company in payment of all or part of the Exercise Price and any withholding
taxes.

SECTION 8.  ADJUSTMENT OF SHARES.

     (a)  General. In the event of a subdivision of the outstanding Stock, a
declaration of a dividend payable in Shares, a declaration of an extraordinary
dividend payable in a form other than Shares in an amount that has a material
effect on the Fair Market Value of the Stock, a combination or consolidation of
the outstanding Stock into a lesser number of Shares, a recapitalization, a
spin-off, a reclassification or a similar occurrence, the Board of Directors
shall make appropriate adjustments in one or more of (i) the number of Shares
available for future grants under Section 4, (ii) the number of Shares covered
by each outstanding Option or (iii) the Exercise Price under each outstanding
Option.

     (b)  Mergers and Consolidations. In the event that the Company is a party
to a merger or consolidation, outstanding Options shall be subject to the
agreement of merger or consolidation. Such agreement, without the Optionees'
consent, may provide for:

          (i)   The continuation of such outstanding Options by the Company (if
     the Company is the surviving corporation);

          (ii)  The assumption of the Plan and such outstanding Options by the
     surviving corporation or its parent;

          (iii) The substitution by the surviving corporation or its parent of
     options with substantially the same terms for such outstanding Options; or

          (iv)  The cancellation of such outstanding Options without payment of
     any consideration.

                                       7
<PAGE>

     (c)  Reservation of Rights. Except as provided in this Section 8, an
Optionee or Purchaser shall have no rights by reason of (i) any subdivision or
consolidation of shares of stock of any class, (ii) the payment of any dividend
or (iii) any other increase or decrease in the number of shares of stock of any
class. Any issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number or
Exercise Price of Shares subject to an Option. The grant of an Option pursuant
to the Plan shall not affect in any way the right or power of the Company to
make adjustments, reclassifications, reorganizations or changes of its capital
or business structure, to merge or consolidate or to dissolve, liquidate, sell
or transfer all or any part of its business or assets.

SECTION 9.  SECURITIES LAW REQUIREMENTS.

     (a)  General. Shares shall not be issued under the Plan unless the issuance
and delivery of such Shares comply with (or are exempt from) all applicable
requirements of law, including (without limitation) the Securities Act of 1933,
as amended, the rules and regulations promulgated thereunder, state securities
laws and regulations, and the regulations of any stock exchange or other
securities market on which the Company's securities may then be traded.

     (b)  Financial Reports. The Company each year shall furnish to Optionees,
Purchasers and stockholders who have received Stock under the Plan its balance
sheet and income statement, unless such Optionees, Purchasers or stockholders
are key Employees whose duties with the Company assure them access to equivalent
information. Such balance sheet and income statement need not be audited.

SECTION 10. NO RETENTION RIGHTS.

     Nothing in the Plan or in any right or Option granted under the Plan shall
confer upon the Purchaser or Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Company (or any Parent or Subsidiary employing or retaining
the Purchaser or Optionee) or of the Purchaser or Optionee, which rights are
hereby expressly reserved by each, to terminate his or her Service at any time
and for any reason, with or without cause.

SECTION 11. DURATION AND AMENDMENTS.

     (a)  Term of the Plan. The Plan, as set forth herein, shall become
effective on the date of its adoption by the Board of Directors, subject to the

THE OPTION GRANTED PURSUANT TO THIS AGREEMENT AND THE SHARES ISSUABLE UPON THE
EXERCISE THEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED WITHOUT AN
EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR AN OPINION OF COUNSEL,
SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
REQUIRED.

                        Kendara, Inc. 1999 Stock Plan:
                            Stock Option Agreement

SECTION 1.   GRANT OF OPTION.

     (a)  Option.  On the terms and conditions set forth in the Notice of Stock
Option Grant and this Agreement, the Company grants to the Optionee on the Date
of Grant the option to purchase at the Exercise Price the number of Shares set
forth in the Notice of Stock Option Grant.  The Exercise Price is agreed to be
at least 100% of the Fair Market Value per Share on the Date of Grant (110% of
Fair Market Value if Section 3(b) of the Plan applies).  This option is intended
to be an ISO or a Nonstatutory Option, as provided in the Notice of Stock Option
Grant.

     (b)  Stock Plan and Defined Terms.  This option is granted pursuant to the
Plan, a copy of which the Optionee acknowledges having received.  The provisions
of the Plan are incorporated into this Agreement by this reference.  Capitalized
terms are defined in Section 14 of this Agreement.

SECTION 2.   RIGHT TO EXERCISE.

     (a)  Exercisability.  Subject to Subsections (b) and (c) below and the
other conditions set forth in this Agreement, all or part of this option may be
exercised prior to its expiration at the time or times set forth in the Notice
of Stock Option Grant.  Shares purchased by exercising this option may be
subject to the Right of Repurchase under Section 7.

     (b)  $100,000 Limitation. If this option is designated as an ISO in the
Notice of Stock Option Grant, then the Optionee's right to exercise this option
shall be deferred to the extent (and only to the extent) that this option
otherwise would not be treated as an ISO by reason of the $100,000 annual
limitation under Section 422(d) of the Code, except that:

          (i)  The Optionee's right to exercise this option shall in any event
     become exercisable at least as rapidly as 20% per year over the five-year
     period commencing on the Date of Grant, unless the Optionee is an officer
     of the Company, an Outside Director or a Consultant; and

          (ii) The Optionee's right to exercise this option shall no longer be
     deferred if (A) the Company is subject to a Change in Control before the
<PAGE>

     Optionee's Service terminates, (B) this option does not remain outstanding,
     (C) this option is not assumed by the surviving corporation or its parent
     and (D) the surviving corporation or its parent does not substitute an
     option with substantially the same terms for this option.

          (c)  Stockholder Approval.  Any other provision of this Agreement
notwithstanding, no portion of this option shall be exercisable at any time
prior to the approval of the Plan by the Company's stockholders.

SECTION 3.   NO TRANSFER OR ASSIGNMENT OF OPTION.

          Except as otherwise provided in this Agreement, this option and the
rights and privileges conferred hereby shall not be sold, pledged or otherwise
transferred (whether by operation of law or otherwise) and shall not be subject
to sale under execution, attachment, levy or similar process.

SECTION 4.   EXERCISE PROCEDURES.

     (a)  Notice of Exercise.  The Optionee or the Optionee's representative may
exercise this option by giving written notice to the Company pursuant to Section
13(c).  The notice shall specify the election to exercise this option, the
number of Shares for which it is being exercised and the form of payment.  The
notice shall be signed by the person exercising this option.  In the event that
this option is being exercised by the representative of the Optionee, the notice
shall be accompanied by proof (satisfactory to the Company) of the
representative's right to exercise this option.  The Optionee or the Optionee's
representative shall deliver to the Company, at the time of giving the notice,
payment in a form permissible under Section 5 for the full amount of the
Purchase Price.

     (b)  Issuance of Shares.  After receiving a proper notice of exercise, the
Company shall cause to be issued a certificate or certificates for the Shares as
to which this option has been exercised, registered in the name of the person
exercising this option (or in the names of such person and his or her spouse as
community property or as joint tenants with right of survivorship).  The Company
shall cause such certificate or certificates to be deposited in escrow or
delivered to or upon the order of the person exercising this option.

     (c)  Withholding Taxes.  In the event that the Company determines that it
is required to withhold any tax as a result of the exercise of this option, the
Optionee, as a condition to the exercise of this option, shall make arrangements
satisfactory to the Company to enable it to satisfy all withholding
requirements.  The Optionee shall also make arrangements satisfactory to the
Company to enable it to satisfy any withholding requirements that may arise in
connection with the vesting or disposition of Shares purchased by exercising
this option.

SECTION 5.   PAYMENT FOR STOCK.

     (a)  Cash.  All or part of the Purchase Price may be paid in cash or cash
equivalents.

                                       2
<PAGE>

     (b)  Surrender of Stock.  All or any part of the Purchase Price may be paid
by surrendering, or attesting to the ownership of, Shares that are already owned
by the Optionee.  Such Shares shall be surrendered to the Company in good form
for transfer and shall be valued at their Fair Market Value on the date when
this option is exercised.  The Optionee shall not surrender, or attest to the
ownership of, Shares in payment of the Purchase Price if such action would cause
the Company to recognize compensation expense (or additional compensation
expense) with respect to this option for financial reporting purposes.

     (c)  Exercise/Sale.  If Stock is publicly traded, all or part of the
Purchase Price and any withholding taxes may be paid by the delivery (on a form
prescribed by the Company) of an irrevocable direction to a securities broker
approved by the Company to sell Shares and to deliver all or part of the sales
proceeds to the Company.

     (d)  Exercise/Pledge.  If Stock is publicly traded, all or part of the
Purchase Price and any withholding taxes may be paid by the delivery (on a form
prescribed by the Company) of an irrevocable direction to pledge Shares to a
securities broker or lender approved by the Company, as security for a loan, and
to deliver all or part of the loan proceeds to the Company.

SECTION 6.   TERM AND EXPIRATION.

     (a)  Basic Term.  This option shall in any event expire on the expiration
date set forth in the Notice of Stock Option Grant, which date is 10 years after
the Date of Grant (five years after the Date of Grant if this option is
designated as an ISO in the Notice of Stock Option Grant and Section 3(b) of the
Plan applies).

     (b)  Termination of Service (Except by Death).  If the Optionee's Service
terminates for any reason other than death, then this option shall expire on the
earliest of the following occasions:

          (i)   The expiration date determined pursuant to Subsection (a) above;

          (ii)  The date three months after the termination of the Optionee's
     Service for any reason other than Disability; or

          (iii) The date six months after the termination of the Optionee's
     Service by reason of Disability.

The Optionee may exercise all or part of this option at any time before its
expiration under the preceding sentence, but only to the extent that this option
had become exercisable for vested shares before the Optionee's Service
terminated.  When the Optionee's Service terminates, this option shall expire
immediately with respect to the number of Shares for which this option is not
yet exercisable and with respect to any Restricted Shares.  In the event that
the Optionee dies after termination of Service but before the expiration of this
option, all or part of this option may be exercised (prior to expiration) by the
executors or administrators of the Optionee's estate or by any person who has
acquired this option directly from the Optionee by beneficiary designation,
bequest or inheritance, but only to the extent that this option had become
exercisable before the Optionee's Service terminated.

                                       3
<PAGE>

     (c)  Death of the Optionee.  If the Optionee dies while in Service, then
this option shall expire on the earlier of the following dates:

          (i)  The expiration date determined pursuant to Subsection (a) above;
     or

          (ii) The date 12 months after the Optionee's death.

All or part of this option may be exercised at any time before its expiration
under the preceding sentence by the executors or administrators of the
Optionee's estate or by any person who has acquired this option directly from
the Optionee by beneficiary designation, bequest or inheritance, but only to the
extent that this option had become exercisable before the Optionee's death. When
the Optionee dies, this option shall expire immediately with respect to the
number of Shares for which this option is not yet exercisable and with respect
to any Restricted Shares.

     (d)  Leaves of Absence.  For any purpose under this Agreement, Service
shall be deemed to continue while the Optionee is on a bona fide leave of
absence, if such leave was approved by the Company in writing and if continued
crediting of Service for such purpose is expressly required by the terms of such
leave or by applicable law (as determined by the Company).

     (e)  Notice Concerning ISO Treatment.  If this option is designated as an
ISO in the Notice of Stock Option Grant, it ceases to qualify for favorable tax
treatment as an ISO to the extent it is exercised (i) more than three months
after the date the Optionee ceases to be an Employee for any reason other than
death or permanent and total disability (as defined in Section 22(e)(3) of the
Code), (ii) more than 12 months after the date the Optionee ceases to be an
Employee by reason of such permanent and total disability or (iii) after the
Optionee has been on a leave of absence for more than 90 days, unless the
Optionee's reemployment rights are guaranteed by statute or by contract.

SECTION 7.   RIGHT OF REPURCHASE.

     (a)  Scope of Repurchase Right. Unless they have become vested in
accordance with the Notice of Stock Option Grant and Subsection (c) below, the
Shares acquired under this Agreement initially shall be Restricted Shares and
shall be subject to a right (but not an obligation) of repurchase by the
Company. The Optionee shall not transfer, assign, encumber or otherwise dispose
of any Restricted Shares, except as provided in the following sentence. The
Optionee may transfer Restricted Shares (i) by beneficiary designation, will or
intestate succession or (ii) to the Optionee's spouse, children or grandchildren
or to a trust established by the Optionee for the benefit of the Optionee or the
Optionee's spouse, children or grandchildren, provided in either case that the
Transferee agrees in writing on a form prescribed by the Company to be bound by
all provisions of this Agreement. If the Optionee transfers any Restricted
Shares, then this Section 7 shall apply to the Transferee to the same extent as
to the Optionee.

     (b)  Condition Precedent to Exercise.  The Right of Repurchase shall be
exercisable with respect to any Restricted Shares only during the 60-day period
next following the later of:

                                       4
<PAGE>

               (i)  The date when the Optionee's Service terminates for any
     reason, with or without cause, including (without limitation) death or
     disability; or

               (ii) The date when such Restricted Shares were purchased by the
     Optionee, the executors or administrators of the Optionee's estate or any
     person who has acquired this option directly from the Optionee by bequest,
     inheritance or beneficiary designation.

          (c)  Lapse of Repurchase Right. The Right of Repurchase shall lapse
with respect to the Shares subject to this option in accordance with the vesting
schedule set forth in the Notice of Stock Option Grant. In addition, the Right
of Repurchase shall lapse and all of the remaining Restricted Shares shall
become vested if (i) the Company is subject to a Change in Control before the
Optionee's Service terminates and (ii) the Right of Repurchase is not assigned
to the entity that employs the Optionee immediately after the Change in Control
or to its parent or subsidiary.

          (d)  Repurchase Cost. If the Company exercises the Right of
Repurchase, it shall pay the Optionee an amount equal to the Exercise Price for
each of the Restricted Shares being repurchased.

          (e)  Exercise of Repurchase Right. The Right of Repurchase shall be
exercisable only by written notice delivered to the Optionee prior to the
expiration of the 60-day period specified in Subsection (b) above.  The notice
shall set forth the date on which the repurchase is to be effected.  Such date
shall not be more than 30 days after the date of the notice.  The certificate(s)
representing the Restricted Shares to be repurchased shall, prior to the close
of business on the date specified for the repurchase, be delivered to the
Company properly endorsed for transfer.  The Company shall, concurrently with
the receipt of such certificate(s), pay to the Optionee the purchase price
determined according to Subsection (d) above.  Payment shall be made in cash or
cash equivalents or by canceling indebtedness to the Company incurred by the
Optionee in the purchase of the Restricted Shares.  The Right of Repurchase
shall terminate with respect to any Restricted Shares for which it has not been
timely exercised pursuant to this Subsection (e).

          (f)  Additional Shares or Substituted Securities.  In the event of the
declaration of a stock dividend, the declaration of an extraordinary dividend
payable in a form other than stock, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities or other property (including money paid
other than as an ordinary cash dividend) which are by reason of such transaction
distributed with respect to any Restricted Shares or into which such Restricted
Shares thereby become convertible shall immediately be subject to the Right of
Repurchase.  Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of the
Restricted Shares.  Appropriate adjustments shall also, after each such
transaction, be made to the price per share to be paid upon the exercise of the
Right of Repurchase in order to reflect any change in the Company's outstanding
securities effected without receipt of consideration therefor; provided,
however, that the aggregate purchase price payable for the Restricted Shares
shall remain the same.

                                       5
<PAGE>

      (g) Termination of Rights as Stockholder.  If the Company makes available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Restricted Shares to be repurchased in accordance with
this Section 7, then after such time the person from whom such Restricted Shares
are to be repurchased shall no longer have any rights as a holder of such
Restricted Shares (other than the right to receive payment of such consideration
in accordance with this Agreement).  Such Restricted Shares shall be deemed to
have been repurchased in accordance with the applicable provisions hereof,
whether or not the certificate(s) therefor have been delivered as required by
this Agreement.

      (h) Escrow.  Upon issuance, the certificates for Restricted Shares shall
be deposited in escrow with the Company to be held in accordance with the
provisions of this Agreement.  Any new, substituted or additional securities or
other property described in Subsection (f) above shall immediately be delivered
to the Company to be held in escrow, but only to the extent the Shares are at
the time Restricted Shares.  All regular cash dividends on Restricted Shares (or
other securities at the time held in escrow) shall be paid directly to the
Optionee and shall not be held in escrow.  Restricted Shares, together with any
other assets or securities held in escrow hereunder, shall be (i) surrendered to
the Company for repurchase and cancellation upon the Company's exercise of its
Right of Repurchase or Right of First Refusal or (ii) released to the Optionee
upon the Optionee's request to the extent the Shares are no longer Restricted
Shares (but not more frequently than once every six months).  In any event, all
Shares which have vested (and any other vested assets and securities
attributable thereto) shall be released within 60 days after the earlier of (i)
the Optionee's cessation of Service or (ii) the lapse of the Right of First
Refusal.

SECTION 8.   RIGHT OF FIRST REFUSAL.

      (a) Right of First Refusal.  In the event that the Optionee proposes to
sell, pledge or otherwise transfer to a third party any Shares acquired under
this Agreement, or any interest in such Shares, the Company shall have the Right
of First Refusal with respect to all (and not less than all) of such Shares.  If
the Optionee desires to transfer Shares acquired under this Agreement, the
Optionee shall give a written Transfer Notice to the Company describing fully
the proposed transfer, including the number of Shares proposed to be
transferred, the proposed transfer price, the name and address of the proposed
Transferee and proof satisfactory to the Company that the proposed sale or
transfer will not violate any applicable federal or state securities laws.  The
Transfer Notice shall be signed both by the Optionee and by the proposed
Transferee and must constitute a binding commitment of both parties to the
transfer of the Shares.  The Company shall have the right to purchase all, and
not less than all, of the Shares on the terms of the proposal described in the
Transfer Notice (subject, however, to any change in such terms permitted under
Subsection (b) below) by delivery of a notice of exercise of the Right of First
Refusal within 30 days after the date when the Transfer Notice was received by
the Company.  The Company's rights under this Subsection (a) shall be freely
assignable, in whole or in part.

      (b) Transfer of Shares.  If the Company fails to exercise its Right of
First Refusal within 30 days after the date when it received the Transfer
Notice, the Optionee may, not later than 90 days following receipt of the
Transfer Notice by the Company, conclude a transfer of the Shares subject to the
Transfer Notice on the terms and conditions described in the Transfer Notice,
provided that any such sale is made in compliance with applicable federal and
state

                                       6
<PAGE>

securities laws and not in violation of any other contractual restrictions
to which the Optionee is bound.  Any proposed transfer on terms and conditions
different from those described in the Transfer Notice, as well as any subsequent
proposed transfer by the Optionee, shall again be subject to the Right of First
Refusal and shall require compliance with the procedure described in Subsection
(a) above.  If the Company exercises its Right of First Refusal, the parties
shall consummate the sale of the Shares on the terms set forth in the Transfer
Notice within 60 days after the date when the Company received the Transfer
Notice (or within such longer period as may have been specified in the Transfer
Notice); provided, however, that in the event the Transfer Notice provided that
payment for the Shares was to be made in a form other than cash or cash
equivalents paid at the time of transfer, the Company shall have the option of
paying for the Shares with cash or cash equivalents equal to the present value
of the consideration described in the Transfer Notice.

      (c) Additional Shares or Substituted Securities.  In the event of the
declaration of a stock dividend, the declaration of an extraordinary dividend
payable in a form other than stock, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities or other property (including money paid
other than as an ordinary cash dividend) which are by reason of such transaction
distributed with respect to any Shares subject to this Section 8 or into which
such Shares thereby become convertible shall immediately be subject to this
Section 8.  Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of the Shares
subject to this Section 8.

      (d) Termination of Right of First Refusal.  Any other provision of this
Section 8 notwithstanding, in the event that the Stock is readily tradable on an
established securities market when the Optionee desires to transfer Shares, the
Company shall have no Right of First Refusal, and the Optionee shall have no
obligation to comply with the procedures prescribed by Subsections (a) and (b)
above.

      (e) Permitted Transfers.  This Section 8 shall not apply to (i) a transfer
by beneficiary designation, will or intestate succession or (ii) a transfer to
the Optionee's spouse, children or grandchildren or to a trust established by
the Optionee for the benefit of the Optionee or the Optionee's spouse, children
or grandchildren, provided in either case that the Transferee agrees in writing
on a form prescribed by the Company to be bound by all provisions of this
Agreement.  If the Optionee transfers any Shares acquired under this Agreement,
either under this Subsection (e) or after the Company has failed to exercise the
Right of First Refusal, then this Section 8 shall apply to the Transferee to the
same extent as to the Optionee.

      (f) Termination of Rights as Stockholder.  If the Company makes available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Shares to be purchased in accordance with this Section 8,
then after such time the person from whom such Shares are to be purchased shall
no longer have any rights as a holder of such Shares (other than the right to
receive payment of such consideration in accordance with this Agreement).  Such
Shares shall be deemed to have been purchased in accordance with the applicable
provisions hereof, whether or not the certificate(s) therefor have been
delivered as required by this Agreement.

                                       7

SECTION 9.   LEGALITY OF INITIAL ISSUANCE.

     No Shares shall be issued upon the exercise of this option unless and until
the Company has determined that:

     (a)  It and the Optionee have taken any actions required to register the
Shares under the Securities Act or to perfect an exemption from the registration
requirements thereof;

     (b)  Any applicable listing requirement of any stock exchange or other
securities market on which Stock is listed has been satisfied; and

     (c)  Any other applicable provision of state or federal law has been
satisfied.

SECTION 10.  NO REGISTRATION RIGHTS.

          The Company may, but shall not be obligated to, register or qualify
the sale of Shares under the Securities Act or any other applicable law.  The
Company shall not be obligated to take any affirmative action in order to cause
the sale of Shares under this Agreement to comply with any law.

SECTION 11.  RESTRICTIONS ON TRANSFER.

     (a)  Securities Law Restrictions.  Regardless of whether the offering and
sale of Shares under the Plan have been registered under the Securities Act or
have been registered or qualified under the securities laws of any state, the
Company at its discretion may impose restrictions upon the sale, pledge or other
transfer of such Shares (including the placement of appropriate legends on stock
certificates or the imposition of stop-transfer instructions) if, in the
judgment of the Company, such restrictions are necessary or desirable in order
to achieve compliance with the Securities Act, the securities laws of any state
or any other law.

     (b)  Market Stand-Off.  In connection with any underwritten public offering
by the Company of its equity securities pursuant to an effective registration
statement filed under the Securities Act, including the Company's initial public
offering, the Optionee shall not directly or indirectly sell, make any short
sale of, loan, hypothecate, pledge, offer, grant or sell any option or other
contract for the purchase of, purchase any option or other contract for the sale
of, or otherwise dispose of or transfer, or agree to engage in any of the
foregoing transactions with respect to, any Shares acquired under this Agreement
without the prior written consent of the Company or its underwriters.  Such
restriction (the "Market Stand-Off") shall be in effect for such period of time
following the date of the final prospectus for the offering as may be requested
by the Company or such underwriters.  In no event, however, shall such period
exceed 180 days.  The Market Stand-Off shall in any event terminate two years
after the date of the Company's initial public offering.  In the event of the
declaration of a stock dividend, a spin-off, a stock split, an adjustment in
conversion ratio, a recapitalization or a similar transaction affecting the
Company's outstanding securities without receipt of consideration, any new,
substituted or additional securities which are by reason of such transaction
distributed with respect to any Shares subject to the Market Stand-Off, or into
which such Shares thereby become convertible, shall immediately be subject to
the Market Stand-Off.  In order to enforce the Market Stand-Off, the Company may
impose stop-transfer instructions with respect to the Shares

                                       8
<PAGE>

acquired under this Agreement until the end of the applicable stand-off period.
The Company's underwriters shall be beneficiaries of the agreement set forth in
this Subsection (b). This Subsection (b) shall not apply to Shares registered in
the public offering under the Securities Act, and the Optionee shall be subject
to this Subsection (b) only if the directors and officers of the Company are
subject to similar arrangements.

     (c)  Investment Intent at Grant.  The Optionee represents and agrees that
the Shares to be acquired upon exercising this option will be acquired for
investment, and not with a view to the sale or distribution thereof.

     (d)  Investment Intent at Exercise.  In the event that the sale of Shares
under the Plan is not registered under the Securities Act but an exemption is
available which requires an investment representation or other representation,
the Optionee shall represent and agree at the time of exercise that the Shares
being acquired upon exercising this option are being acquired for investment,
and not with a view to the sale or distribution thereof, and shall make such
other representations as are deemed necessary or appropriate by the Company and
its counsel.

     (e)  Legends.  All certificates evidencing Shares purchased under this
Agreement shall bear the following legend:

     "THE SHARES REPRESENTED HEREBY MAY NOT BE SOLD, ASSIGNED,
     TRANSFERRED, ENCUMBERED OR IN ANY MANNER DISPOSED OF, EXCEPT IN
     COMPLIANCE WITH THE TERMS OF A WRITTEN AGREEMENT BETWEEN THE
     COMPANY AND THE REGISTERED HOLDER OF THE SHARES (OR THE
     PREDECESSOR IN INTEREST TO THE SHARES). SUCH AGREEMENT GRANTS TO
     THE COMPANY CERTAIN RIGHTS OF FIRST REFUSAL UPON AN ATTEMPTED
     TRANSFER OF THE SHARES AND CERTAIN REPURCHASE RIGHTS UPON
     TERMINATION OF SERVICE WITH THE COMPANY. THE SECRETARY OF THE
     COMPANY WILL UPON WRITTEN REQUEST FURNISH A COPY OF SUCH
     AGREEMENT TO THE HOLDER HEREOF WITHOUT CHARGE."

All certificates evidencing Shares purchased under this Agreement in an
unregistered transaction shall bear the following legend (and such other
restrictive legends as are required or deemed advisable under the provisions of
any applicable law):

     "THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED,
     OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION
     THEREOF UNDER SUCH ACT OR AN OPINION OF COUNSEL, SATISFACTORY TO
     THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
     REQUIRED."

     (f)  Removal of Legends.  If, in the opinion of the Company and its
counsel, any legend placed on a stock certificate representing Shares sold under
this Agreement is no longer

                                       9
<PAGE>

required, the holder of such certificate shall be entitled to exchange such
certificate for a certificate representing the same number of Shares but without
such legend.

     (g)  Administration.  Any determination by the Company and its counsel in
connection with any of the matters set forth in this Section 11 shall be
conclusive and binding on the Optionee and all other persons.

SECTION 12.  ADJUSTMENT OF SHARES.

          In the event of any transaction described in Section 8(a) of the Plan,
the terms of this option (including, without limitation, the number and kind of
Shares subject to this option and the Exercise Price) shall be adjusted as set
forth in Section 8(a) of the Plan.  In the event that the Company is a party to
a merger or consolidation, this option shall be subject to the agreement of
merger or consolidation, as provided in Section 8(b) of the Plan.

SECTION 13.  MISCELLANEOUS PROVISIONS.

     (a)  Rights as a Stockholder.  Neither the Optionee nor the Optionee's
representative shall have any rights as a stockholder with respect to any Shares
subject to this option until the Optionee or the Optionee's representative
becomes entitled to receive such Shares by filing a notice of exercise and
paying the Purchase Price pursuant to Sections 4 and 5.

     (b)  No Retention Rights.  Nothing in this option or in the Plan shall
confer upon the Optionee any right to continue in Service for any period of
specific duration or interfere with or otherwise restrict in any way the rights
of the Company (or any Parent or Subsidiary employing or retaining the Optionee)
or of the Optionee, which rights are hereby expressly reserved by each, to
terminate his or her Service at any time and for any reason, with or without
cause.

     (c)  Notice.  Any notice required by the terms of this Agreement shall be
given in writing and shall be deemed effective upon personal delivery or upon
deposit with the United States Postal Service, by registered or certified mail,
with postage and fees prepaid.  Notice shall be addressed to the Company at its
principal executive office and to the Optionee at the address that he or she
most recently provided to the Company.

     (d)  Entire Agreement.  The Notice of Stock Option Grant, this Agreement
and the Plan constitute the entire contract between the parties hereto with
regard to the subject matter hereof.  They supersede any other agreements,
representations or understandings (whether oral or written and whether express
or implied) which relate to the subject matter hereof.
