granted under the Plan have lapsed. However, all Options shall be granted, if at
all, by September 27, 2010.

the Board. All questions of interpretation of the Plan or of any Option shall be
determined by the Board, and such determinations shall be final and binding upon
all persons having an interest in the Plan or such Option. Any officer of
Immersion shall have the authority to act on behalf of Immersion with respect to
any matter, right, obligation, determination or election which is the

the Plan and subject to the provisions of the Plan, the Board shall have the
full and final power and authority, in its sole discretion:

               (a)  to determine the persons to whom, and the time or times at

Company on any of the foregoing, and (vii) all other terms, conditions and
restrictions applicable to the Option or such shares not inconsistent with the
terms of the Plan;

               (d)  to approve one or more forms of Option Agreement;

               (e)  to amend, modify, extend, or renew, or grant a new Option in
substitution for, any Option or to waive any restrictions or conditions
applicable to any Option or any shares acquired upon the exercise thereof;

               (f)  to amend the exercisability of any Option or the vesting of
any shares acquired upon the exercise thereof, including with respect to the
period following an Optionee's termination of employment or service with the
Participating Company;

               (g)  to prescribe, amend or rescind rules, guidelines and
policies relating to the Plan, or to adopt supplements to, or alternative
versions of, the Plan, including, without limitation, as the Board deems
necessary or desirable to comply with the laws of, or to accommodate the tax
policy or custom of, foreign jurisdictions whose citizens may be granted
Options; and

               (h)  to correct any defect, supply any omission or reconcile any
inconsistency in the Plan or any Option Agreement and to make all other
determinations and take such other actions with respect to the Plan or any
Option as the Board may deem advisable to the extent consistent with the Plan
and applicable law.

          3.3. COMMITTEE COMPLYING WITH SECTION 162(m). The grant of any Option
which might reasonably be anticipated to result in the payment of employee
remuneration that would otherwise exceed the limit on employee remuneration
deductible for income tax purposes pursuant to Section 162(m) shall be approved
by a committee of "outside directors" of Immersion within the meaning of Section
162(m).

     4.   SHARES SUBJECT TO PLAN.

          4.1. MAXIMUM NUMBER OF SHARES ISSUABLE. Subject to adjustment as
provided by Section 4.2, the maximum aggregate number of shares of Stock that
may be issued under the Plan shall be 766,322 and shall consist of authorized
but unissued or reacquired shares of Stock or any combination thereof. No
Optionee may be granted more than 300,000 shares of Stock in any calendar year.
If an outstanding Option for any reason expires or is terminated or canceled or
shares of Stock acquired, subject to repurchase, upon the exercise of an Option
are repurchased by Immersion, the shares of Stock allocable to the unexercised
portion of such Option, or such repurchased shares of Stock, shall again be
available for issuance under the Plan.

          4.2. ADJUSTMENTS FOR CHANGES IN CAPITAL STRUCTURE. In the event of any
stock dividend, stock split, reverse stock split, recapitalization, combination,
reclassification or similar change in the capital structure of Immersion,

                                       4
   5

appropriate adjustments shall be made in the number and class of shares subject
to the Plan and to any outstanding Options and in the exercise price per share
of any outstanding Options. If a majority of the shares which are of the same
class as the shares that are subject to outstanding Options are exchanged for,
converted into, or otherwise become (whether or not pursuant to an Ownership
Change Event, as defined in Section 8.1) shares of another corporation (the "NEW
SHARES"), the Board may unilaterally amend the outstanding Options to provide
that such Options are exercisable for New Shares. In the event of any such
amendment, the number of shares subject to, and the exercise price per share of,
the outstanding Options shall be adjusted in a fair and equitable manner as
determined by the Board, in its sole discretion. Notwithstanding the foregoing,
any fractional share resulting from an adjustment pursuant to this Section 4.2
shall be rounded up or down to the nearest whole number, as determined by the
Board, provided, however, that in no event may the exercise price of any Option
be decreased to an amount less than the par value, if any, of the stock subject
to the Option. The adjustments determined by the Board pursuant to this Section
4.2 shall be final, binding and conclusive.

     5.   ELIGIBILITY. Options may be granted only to Employees and directors of
the Participating Company. For purposes of the foregoing sentence, "Employees"
shall include prospective Employees to whom Options are granted in connection
with written offers of employment with the Participating Company. Eligible
persons may be granted more than one Option.

     6.   TERMS AND CONDITIONS OF OPTIONS. Options shall be evidenced by Option
Agreements specifying the number of shares of Stock covered thereby, in such
form as the Board shall from time to time establish, executed by Immersion and
the Optionee to whom such Option is granted; provided, however, that the failure
by Immersion, the Optionee, or both, to execute the Option Agreement shall not
invalidate the granting of an Option. Option Agreements may incorporate all or
any of the terms of the Plan by reference and shall comply with and be subject
to the following terms and conditions:

          6.1. EXERCISE PRICE. The exercise price for each Option shall be
established in the sole discretion of the Board; provided, however, that the
exercise price per share for an Option shall be not less than the Fair Market
Value of a share of Stock on the effective date of grant of the Option.

          6.2. EXERCISE PERIOD. Options shall be exercisable at such time or
times, or upon such event or events, and subject to such terms, conditions,
performance criteria, and restrictions as shall be determined by the Board and
set forth in the Option Agreement evidencing such Option; provided, however,
that (a) no Option shall be exercisable after the expiration of 10 years after
the effective date of grant of such Option, and (b) no Option granted to a
prospective Employee may become exercisable

                                       5
   6

prior to the date on which such person commences service with the Participating
Company.

          6.3. PAYMENT OF EXERCISE PRICE.

               (a)  FORMS OF CONSIDERATION AUTHORIZED. Except as otherwise
provided below, payment of the exercise price for the number of shares of Stock
being purchased pursuant to any Option shall be made in any form of lawful
consideration as the Board my approve from time to time, including without
limitation: (i) cash, check, or cash equivalent, (ii) by tender to the Company
of whole shares of Stock owned by the Optionee having a Fair Market Value (as
determined by the Company without regard to any restrictions on transferability
applicable to such stock by reason of federal or state securities laws or
agreements with an underwriter for the Company) not less than the aggregate
Exercise Price, (iii) assignment of the proceeds of a sale or loan with respect
to some or all of the shares being acquired upon the exercise of the Option
(including, without limitation, through an exercise complying with the
provisions of Regulation T as promulgated from time to time by the Board of
Governors of the Federal Reserve System (a "CASHLESS EXERCISE")), (iv) the
Optionee's recourse promissory note in a form approved by Immersion, or (v) any
combination of the foregoing. The Board may at any time or from time to time, by
adoption of or by amendment to the standard forms of Option Agreement described
in Section 7, or by other means, grant Options which do not permit all of the
foregoing forms of consideration to be used in payment of the exercise price or
which otherwise restrict one or more forms of consideration

               (b)  TENDER OF STOCK. Notwithstanding the foregoing, an Option
may not be exercised by tender to Immersion of shares of Stock to the extent
such tender of Stock would constitute a violation of the provisions of any law,
regulation or agreement restricting the redemption of Immersion's stock.

               (c)  CASHLESS EXERCISE. Immersion reserves, at any and all times,
the right, in Immersion's sole and absolute discretion, to establish, decline to
approve or terminate any program or procedures for the exercise of Options by
means of a Cashless Exercise.

               (d)  PAYMENT BY PROMISSORY NOTE. No promissory note shall be
permitted if the exercise of an Option using a promissory note would be a
violation of any law. Any permitted promissory note shall be on such terms as
the Board shall determine at the time the Option is granted. The Board shall
have the authority to permit or require the Optionee to secure any promissory
note used to exercise an Option with the shares of Stock acquired upon the
exercise of the Option or with other collateral acceptable to Immersion. Unless
otherwise provided by the Board, if Immersion at any time is subject to
regulations promulgated by the Board of Governors of the Federal Reserve System
or any other governmental entity affecting the extension of credit in

                                       6
   7

connection with Immersion's securities, any promissory note shall comply with
such applicable regulations, and the Optionee shall pay the unpaid principal and
accrued interest, if any, to the extent necessary to comply with such applicable
regulations.

               6.4. TAX WITHHOLDING. Immersion shall have the right, but not the
obligation, to deduct from the shares of Stock issuable upon the exercise of an
Option, or to accept from the Optionee the tender of, a number of whole shares
of Stock having a Fair Market Value, as determined by Immersion, equal to all or
any part of the federal, state, local and foreign taxes, if any, required by law
to be withheld by the Participating Company with respect to such Option or the
shares acquired upon the exercise thereof. Alternatively or in addition, in its
sole discretion, Immersion shall have the right to require the Optionee, through
payroll withholding, cash payment or otherwise, including by means of a Cashless
Exercise, to make adequate provision for any such tax withholding obligations of
the Participating Company arising in connection with the Option or the shares
acquired upon the exercise thereof. Immersion shall have no obligation to
deliver shares of Stock or to release shares of Stock from an escrow established
pursuant to the Option Agreement until the Participating Company's tax
withholding obligations have been satisfied by the Optionee.

     7.   STANDARD FORMS OF OPTION AGREEMENT.

          7.1. GENERAL. Unless otherwise provided by the Board at the time the
Option is granted, an Option shall comply with and be subject to the terms and
conditions set forth in the form of Option Agreement adopted by the Board
concurrently with its adoption of the Plan and as amended from time to time.

          7.2. STANDARD TERM OF OPTIONS. Except as otherwise provided in Section
6.2 or by the Board in the grant of an Option, any Option granted hereunder
shall have a term of 10 years from the effective date of grant of the Option.

          7.3. AUTHORITY TO VARY TERMS. The Board shall have the authority from
time to time to vary the terms of any of the standard form of Option Agreement
described in this Section 7 either in connection with the grant or amendment of
an individual Option or in connection with the authorization of a new standard
form or forms; provided, however, that the terms and conditions of any such new,
revised or amended standard form or forms of Option Agreement are not
inconsistent with the terms of the Plan. Such authority shall include, but not
be limited to, the authority to grant Options which are not immediately
exercisable.

     8.   TRANSFER OF CONTROL.

          8.1. DEFINITIONS.

                                       7
   8

               (a)  An "OWNERSHIP CHANGE EVENT" shall be deemed to have occurred
if any of the following occurs with respect to Immersion:

                    (i)  the direct or indirect sale or exchange in a single or
series of related transactions by the stockholders of Immersion of more than 50%
of the voting stock of Immersion;

                    (ii) a merger or consolidation in which Immersion is a
party;

                    (iii) the sale, exchange, or transfer of all or
substantially all of the assets of Immersion; or

                    (iv) a liquidation or dissolution of Immersion.

               (b)  A "TRANSFER OF CONTROL" shall mean an Ownership Change Event
or a series of related Ownership Change Events (collectively, the "TRANSACTION")
wherein the stockholders of Immersion immediately before the Transaction do not
retain immediately after the Transaction, in substantially the same proportions
as their ownership of shares of Immersion's voting stock immediately before the
Transaction, direct or indirect beneficial ownership of more than 50% of the
total combined voting power of the outstanding voting stock of Immersion or the
corporation or corporations to which the assets of Immersion were transferred
(the "TRANSFEREE CORPORATION(S)"), as the case may be. For purposes of the
preceding sentence, indirect beneficial ownership shall include, without
limitation, an interest resulting from ownership of the voting stock of one or
more corporations which, as a result of the Transaction, own Immersion or the
Transferee Corporation(s), as the case may be, either directly or through one or
more subsidiary corporations. The Board shall have the right to determine
whether multiple sales or exchanges of the voting stock of Immersion or multiple
Ownership Change Events are related, and its determination shall be final,
binding and conclusive.

          8.2. EFFECT OF TRANSFER OF CONTROL ON OPTIONS. The Board shall give
Optionees notice 30 days in advance of any Transfer of Control. In the event of
a Transfer of Control, the surviving, continuing, successor, or purchasing
corporation or parent corporation thereof, as the case may be (the "ACQUIRING
CORPORATION"), may either assume Immersion's rights and obligations under
outstanding Options or substitute for outstanding Options substantially
equivalent options for the Acquiring Corporation's stock. For purposes of this
Section 8.2, an Option shall be deemed assumed if, following the Transfer of
Control, the Option (or a substitute) confers the right to purchase in
accordance with its terms and conditions, for each share of Stock subject to the
Option immediately prior to the Transfer of Control, the consideration (whether
stock, cash or other securities or property) to which a holder of a share of
Stock on the effective date of the Transfer of Control was entitled. Any Options



                                       8
   9

which are neither assumed or substituted for by the Acquiring Corporation in
connection with the Transfer of Control nor exercised as of the date of the
Transfer of Control shall terminate and cease to be outstanding effective as of
the date of the Transfer of Control. Notwithstanding the foregoing, shares
acquired upon exercise of an Option prior to the Transfer of Control and any
consideration received pursuant to the Transfer of Control with respect to such
shares shall continue to be subject to all applicable provisions of the Option
Agreement evidencing such Option except as otherwise provided in such Option
Agreement. Furthermore, notwithstanding the foregoing, if the corporation the
stock of which is subject to the outstanding Options immediately prior to an
Ownership Change Event described in Section 8.1(a)(i) constituting a Transfer of
Control is the surviving or continuing corporation and immediately after such
Ownership Change Event less than 50% of the total combined voting power of its
voting stock is held by another corporation or by other corporations that are
members of an affiliated group within the meaning of Section 1504(a) of the Code
without regard to the provisions of Section 1504(b) of the Code, the outstanding
Options shall not terminate unless the Board otherwise provides in its sole
discretion.

     9.   NONTRANSFERABILITY OF OPTIONS. During the lifetime of the Optionee, an
Option shall be exercisable only by the Optionee or the Optionee's guardian or
legal representative. No Option shall be assignable or transferable by the
Optionee, except by will or by the laws of descent and distribution.

     10.  INDEMNIFICATION. In addition to such other rights of indemnification
as they may have as officers, directors and employees of Immersion, employees of
Immersion to whom authority to act for Immersion is delegated shall be
indemnified by Immersion against all reasonable expenses, including attorneys'
fees, actually and necessarily incurred in connection with the defense of any
action, suit or proceeding, or in connection with any appeal therein, to which
they or any of them may be a party by reason of any action taken or failure to
act under or in connection with the Plan, or any right granted hereunder, and
against all amounts paid by them in settlement thereof (provided such settlement
is approved by independent legal counsel selected by Immersion) or paid by them
in satisfaction of a judgment in any such action, suit or proceeding, except in
relation to matters as to which it shall be adjudged in such action, suit or
proceeding that such person is liable for gross negligence, bad faith or
intentional misconduct in duties; provided, however, that within 60 days after
the institution of such action, suit or proceeding, such person shall offer to
Immersion, in writing, the opportunity at its own expense to handle and defend
the same.

     11.  TERMINATION OR AMENDMENT OF PLAN. Subject to changes in any applicable
law, regulations or rules to which the Plan is subject, the Board may terminate
or amend the Plan at any time. However, no termination or amendment of the Plan
may adversely affect any then outstanding Option or any unexercised portion
thereof, without

                                       9
   10

the consent of the Optionee, unless such termination or amendment is necessary
to comply with any applicable law, regulations or rules.
