Product Model Technology for use in any Planar Force Feedback Cursor Control
Device in the Planar Force Feedback Cursor Control Field of Use that has
substantially similar force feedback functionality to a Planar Force Feedback
Cursor Control Device commercially released by Logitech, are less than the
applicable rates for such Planar Force Feedback Cursor Control Device herein,
Immersion hereby agrees that it will advise Logitech of such lesser royalty
rates as of the date such lesser royalties became effective for such other third
party. Such comparison will be on the basis of cash royalty rates only and will
not apply in situations where part of the consideration is a cross-license which
is taken into account in setting the cash royalty. Logitech shall have the right
to have an independent auditor mutually agreed upon by Logitech and Immersion
audit Immersion business records related to the performance of its obligations
under this Section 3.3 on an annual basis. Logitech shall pay the costs of such
audit, unless such audit reveals that Immersion is not in compliance with this
Section 3.3, in which case other than termination Logitech's sole and


                                       8
<PAGE>   9

exclusive remedy will be, at Logitech's option, Immersion shall promptly credit
Logitech's account or repay any overpayment, the parties will amend the
Agreement to reflect the most favorable Royalty Rate and Immersion shall pay the
reasonable costs of such audit. Such audit shall be preceded by at least five
(5) business days advance written notice and shall be performed during normal
business hours by the auditor. The auditor shall have access to only those books
and records of Immersion that are reasonably necessary to determine the
compliance by Immersion with this Agreement. Any and all non-public information
related to Immersion or its business revealed in the course of such audit shall
be kept confidential by the auditor and by Logitech, and shall not be disclosed
by the auditor to anyone other than employees or professional advisors of
Logitech who have a reasonable need to know in connection with such audit, or
used for any purpose, except to the extent reasonably necessary to determine
whether Immersion is in compliance with this Agreement.

        3.4 PAYMENTS AND REPORTS. The royalties to be paid by Logitech to
Immersion hereunder shall be due forty-five (45) days after the close of each
Quarter. Royalty reports setting forth the royalty calculation by Product Model
and identifying whether the sales were made by Logitech or Logitech Affiliates
shall be included with such payments. Logitech will pay and account to Immersion
for royalties due hereunder with respect to sales or other disposition of
Royalty Bearing Products by any Logitech Affiliates, and for that purpose, sales
of Royalty Bearing Products by any Logitech Affiliate (other than sales or other
disposition by an Affiliate to Logitech or to another Logitech Affiliate) will
be deemed to be sales by Logitech.

        3.5 AUDIT RIGHTS OF ROYALTY PAYMENTS. Immersion shall have the right to
have an independent auditor mutually agreed by Logitech and Immersion audit the
method used to calculate the average sales price, as well as the sales data
pursuant to Section 1.19 ("Net Receipts") and the royalty payments of Logitech
for itself and its Affiliates on an annual basis, but shall pay the costs of
such audit, unless such audit reveals any underpayment of royalties in an amount
greater than five percent (5%) of actual royalties due for any Year, in which
case Logitech shall promptly remit an amount equal to the underpayment and shall
pay the reasonable costs of such audit. Such audit shall be preceded by at least
five (5) business days advance written notice and shall be performed during
normal business hours by the auditor. The auditor shall have access to only
those books and records of Logitech which are reasonably necessary to determine
the relevant sales royalties due for Royalty Bearing Products for Logitech
itself and its Affiliates and the correctness of the royalty payments hereunder.
Any and all non-public information related to Logitech, its Affiliates, or their
business revealed in the course of such audit shall be kept confidential by the
auditor and by Immersion, and shall not be disclosed by the auditor to anyone
other than employees or professional advisors of Immersion who have a reasonable
need to know in connection with such audit, or used for any purpose, except to
the extent reasonably necessary to determine the correctness of royalty payments
made hereunder.

Immersion or recommended by Immersion pursuant to a specific written obligation
in the Specifications in Exhibit A of the Development Agreement to make a
recommendation; or (e) Immersion's compliance with a Specification or any
aspects or portions of the Specification which "inherently" (as defined below)
infringes any patent. For the purposes of this Agreement "inherently" means that
any device or aspect or portion of a device which was in conformance with the
Specification would infringe such patent.

            6.5.3 EXCEPTIONS WITH RESPECT TO PATENTS ISSUED AFTER THE EFFECTIVE
DATE. The provisions of this Section 6.5.3 ("Exceptions With Respect to Patents
Issued After the Effective Date") shall apply only with respect to a United
States patent issued after the Effective Date (an "After-Issued Patent").

                  (a) NOTICE BY IMMERSION AND SUPPLY OF MODIFIED OR SUBSTITUTE
TECHNOLOGY. Logitech agrees to promptly notify Immersion if Logitech becomes
aware of an After-Issued Patent which Logitech reasonably believes is infringed
by any Immersion Product Model Technology that is the subject of an indemnity
obligation by Immersion hereunder. If upon receipt of notice from Logitech or
independently, Immersion becomes aware of an After-Issued Patent which Immersion
reasonably believes is infringed by any Immersion Product Model Technology that
is the subject of an indemnity obligation by Immersion hereunder, then


                                       14
<PAGE>   15

Immersion will notify Logitech in writing of such patent (the date of such
notice being referred to as the "Notice Date"). Within fifteen (15) days after
the Notice Date, Immersion shall supply Logitech with a written description and
cost estimate of a proposed redesign of the infringing Immersion Product Model
Technology to avoid the infringement. As reasonably promptly thereafter as
possible, Immersion shall supply Logitech with a modification to the affected
Immersion Product Model Technology so that the incorporated Immersion Product
Model Technology becomes noninfringing or substitute for the infringing
Immersion Product Model Technology other technology that conforms to the
Specifications in Exhibit A of the Development Agreement (which shall itself be
deemed to be Immersion Product Model Technology) or, if neither of the foregoing
are reasonably possible, procure for Logitech the right to continue to use such
Immersion Product Model Technology. If Immersion is unable to procure for
Logitech the right to continue to use such Immersion Product Model Technology
under commercially reasonable terms, as determined by Immersion, Immersion may,
in the alternative, refund to Logitech all royalties received by Immersion under
the Agreement relating to the allegedly infringing Immersion Product Model
Technology (reflecting any discounts granted to Logitech, less an amount for
depreciation calculated in a straight-line basis over an assumed useful life of
three (3) years).

                  (b) COSTS NOT COVERED BY INDEMNITY FOR AFTER-ISSUED PATENTS.
Immersion shall have no obligation to indemnify Logitech for infringement of
such After-Issued Patents with respect to any units of a Planar Force Feedback
Cursor Control Device which are distributed or used by Logitech after the Notice
Date. Immersion shall have no liability hereunder to reimburse Logitech for any
lost inventory, retooling or other manufacturing costs incurred by Logitech that
result from Logitech's incorporation of such modified or substitute technology
in order to avoid infringement of an After-Issued Patent.

                  (c) ELECTION BY LOGITECH OF ALTERNATIVE REMEDY.
Notwithstanding the foregoing provisions, in any instance in which Immersion is
prepared and capable of supplying to Logitech modified or substitute technology
to avoid infringement of an After-Issued Patent, Logitech may, within a
reasonable time after receiving Immersion's written description and cost
estimate of Immersion's proposed redesign, elect either (i) to request, in
writing, that Immersion pursue a license under the After-Issued Patents on
behalf of Logitech to continue using the affected Immersion Product Model
Technology, in which event if such license would cost Immersion more than the
cost estimate provided by Immersion to Logitech, under the terms of (a) above,
to supply modified or substitute technology to avoid infringement, then Logitech
shall pay the difference between such costs, or (ii) to request, in writing,
that Logitech be allowed to continue to use the Immersion Product Model
Technology in unaltered form, in which event Immersion shall have no obligations
of indemnity or defense hereunder with respect to any infringement of the
After-Issued Patents resulting from units of Planar Force Feedback Cursor
Control Devices incorporating the unaltered Immersion Product Model Technology
used or distributed by Logitech after the Notice Date. If Immersion pursues the
license described in (i) above, and is unable to procure such a license,
Immersion will not be in breach of this Agreement.

<PAGE>   16

        6.6 REMEDIES IN THE EVENT OF PROHIBITION OF USE. The provisions and
remedies set forth in this Section 6.6 ("Remedies In the Event of Prohibition of
Use") shall continue to be applicable with respect to any copyright infringement
or trade secret misappropriation under the terms of Section 6.2 ("Copyright
Infringement and Trade Secret Misappropriation"), and any After-Issued Patents
for which Immersion does not supply written notice to Logitech in accordance
with Section 6.5.3 (a) ("Notice by Immersion and Supply of Modified or
Substitute Technology") and any U.S. Patents issued prior to the Effective Date
of this Agreement. If a preliminary or final judgment shall be obtained against
Logitech's use, sale or distribution of a Planar Force Feedback Cursor Control
Device that incorporates any Immersion Product Model Technology based
infringement within the scope of the indemnity set forth in Section 6.1
("Trademark Infringement indemnification by Immersion"), 6.2 ("Copyright
Infringement and Trade Secret Misappropriation Indemnification by Immersion") or
6.5 (Patent Infringement Indemnification by Immersion") (subject to the
exceptions set forth therein), or if any Immersion Product Model Technology is,
or in Immersion's opinion, is likely to become, subject to a claim for such
infringement, then Immersion shall, at its expense, either (a) modify the
Immersion Product Model Technology so that the incorporated Immersion Product
Model Technology becomes noninfringing, or (b) procure for Logitech the right to
continue to use such Immersion Product Model Technology, or (c) substitute for
the infringing Immersion Product Model Technology other technology that conforms
to the Specifications in Exhibit A of the Development Agreement (which shall
itself be deemed to be Immersion Product Model Technology). If (a), (b) or (c)
above are not commercially reasonable alternatives in Immersion's opinion,
Immersion shall refund to Logitech all royalties received by Immersion under
this Agreement relating to the allegedly infringing Immersion Product Model
Technology (reflecting any discounts granted to Logitech, less an amount for
depreciation calculated in a straight-line basis over an assumed useful life of
three (3) years).

        6.7 INDEMNITY BY LOGITECH. Subject to the limitations of liability set
forth in Section 7 ("Limitations of Liability"), and subject to prompt
notification by Immersion, cooperation by Immersion and control of all
litigation and/or settlement by Logitech, Logitech shall indemnify, defend and
hold harmless Immersion from and against any and all Costs suffered or incurred
by Immersion to the extent such Costs are suffered or incurred by Immersion in
the situations listed in the exceptions (i) through (iii) enumerated in Section
6.2.2 ("Exceptions"), and in the exceptions (a) through (e) enumerated in
Section 6.5.2 ("Exceptions to the Scope of Indemnity"), and/or in the situation
where Logitech and Immersion agree that Logitech will be allowed to continue to
use the Immersion Product Model Technology in unaltered form in accordance with
subsection (ii) of Section 6.5.3 (c) ("Election by Logitech of Alternative
Remedy"), provided that such situations arise because of Logitech's, its
subcontractors' or affiliates' use and modifications.

8.      THIRD PARTY ENFORCEMENT

        Immersion shall not have any obligation or duty under this Agreement to
any party, including but not limited to Logitech to enforce any patents or
Licensed Patents against any third party infringing any claim or claims of any
patent and/or the Licensed Patents provided, however, that should Logitech
become aware of any actual infringement of the Licensed Patents by a Planar
Force Feedback Cursor Control Device distributed in the Planar Force Feedback
Cursor Control Field of Use by a third party, which Planar Force Feedback Cursor
Control Device directly competes with a Planar Force Feedback Cursor Control
Device currently shipped by Logitech as a formal product release which is
covered by the Licensed Patents, Logitech will promptly communicate the details
to Immersion. Immersion shall thereupon, within thirty (30) days of being made
aware by Logitech of such infringement, send copies of the relevant Licensed
Patents to such third party, however, Immersion shall have the right to take no
further action or whatever action Immersion deems necessary, including cease and
desist letters, negotiation, the filing of lawsuits, and/or settlement to
terminate such infringement and the strategy and/or conclusion of such action or
settlement shall be within Immersion's sole discretion. Logitech shall cooperate
with Immersion if Immersion takes any such action but all expenses of Immersion
shall be borne by Immersion. If Immersion recovers any damages or compensation
for any action Immersion takes hereunder, including any settlement, Immersion
shall retain one hundred percent (100%) of such damages. If Immersion does not
elect to take such further action hereunder within ninety (90) days of being
made aware of such infringement by Logitech, then Logitech shall have the right,
but not the obligation, to provide Immersion with a Patent Enforcement
Justification, as defined below, and if the proposed enforcement action meets
the Patent Enforcement Justification criteria, Logitech may take and control any
such action, subject to Immersion's absolute right to control any and all
assertions or admissions


                                       18
<PAGE>   19

which relate to the scope or validity of Immersion's Licensed Patents. For
purposes of this Section 8 ("Third Party Enforcement"), a Patent Enforcement
Justification is a written report prepared by Logitech which includes: (i) the
name and address of the entity manufacturing the Planar Force Feedback Cursor
Control Device that is allegedly infringing the Licensed Patents and the names
and addresses of any entities distributing such Planar Force Feedback Cursor
Control Device, (ii) an analysis of which of the Licensed Patent claims are
infringed, (iii) a comparison of the allegedly infringing Planar Force Feedback
Cursor Control Device and the affected Planar Force Feedback Cursor Control
Device distributed by Logitech with which such allegedly infringing Planar Force
Feedback Cursor Control Device competes (which comparison analyzes the
competitive threat as to (a) feature and function, (b) positioning, and (c)
price point), (iv) the number of units of the Planar Force Feedback Cursor
Control Device sold by Logitech in the most recent four (4) full Quarters and,
if known or reasonably estimable, the number or estimate of the number of units
of the allegedly infringing Planar Force Feedback Cursor Control Device sold in
the most recent four (4) full Quarters, on a geographic area basis. The criteria
which must be met by such report, in order to permit Logitech to "justify" and
to go forward with an infringement action, as are follows:

                        (i) Logitech must be selling over 150,000 units of the
affected Planar Force Feedback Cursor Control Device in the market in which the
infringement is occurring during the most recent four (4) full Quarters or, if
the Product Launch occurred during the most recent four (4) full Quarters,
Logitech reasonably estimates in good faith that it will sell over 150,000 units
of the affected Planar Force Feedback Cursor Control Device in the market in
which the infringement is occurring during the next four (4) full Quarters;

                        (ii) the allegedly infringing Planar Force Feedback
Cursor Control Device must be substantially similar to the affected Planar Force
Feedback Cursor Control Device as to features and functions such that the
allegedly infringing Planar Force Feedback Cursor Control Device is having or
reasonably will have a serious impact on the sales of the affected Logitech
Planar Force Feedback Cursor Control Device;

                        (iii) the Licensed Patents to be enforced against the
allegedly infringing Planar Force Feedback Cursor Control Device also cover the
affected Logitech Planar Force Feedback Cursor Control Device;

                        (iv) the number of units of the allegedly infringing
Planar Force Feedback Cursor Control Device sold in the market in which the
infringement is occurring in the most recent four (4) full Quarters or
reasonably estimated in good faith to be sold in the next four (4) full Quarters
must meet or exceed 150,000 units; and

                        (v) Logitech has included the applicable Licensed Patent
numbers on the affected Planar Force Feedback Cursor Control Device in
accordance with the terms of Section 2.5 ("Label Requirements").

If the aforementioned criteria are met, Immersion will cooperate with Logitech,
at Logitech's expense, including but not limited to joining any legal
proceedings as a named plaintiff to the extent required to confer jurisdiction,

                                   EXHIBIT A
                                 SPECIFICATION

        Immersion shall develop a Mouse Product to conform to the following
basic specifications: The Mouse Product shall be a two degree of freedom mouse
controller with active force feedback functionality along each of the two
displacement axes. The Mouse Product will be fixed by a linkage to a mouse pad
that houses the actuators and sensors. The Mouse Product will allow both
absolute position data and relative position data to be reported to the host
computer. The Mouse Product must be compatible with Intel based personal
computers (or equivalent) running Microsoft Windows 98 and NT operating systems.
It must connect to the PC through a universal Serial Bus ("USB") interface using
the USB communication protocol for "HID" and/or "PID" class devices (or HID
equivalent). In addition to receiving position data and button press data from
the Mouse Product across the USB, the host computer will command force
sensations on the Mouse Product by sending a high level force command with
command parameters across the USB. The completed work must include host drivers,
firmware and electromechanical hardware that work together to allow cursor
related force feedback sensations to be generated by a processor on-board the
Mouse Product (for example, physical detent sensations when traversing a menu
item). Said sensations must be appropriately coordinated with events running in
host software applications. The programming of coordination between force
sensations and software events will be achieved using a high-level Application
Programming Interface ("API") that allows software developers to command force
feedback sensations from their applications. For gaming applications, the
Windows API will use the "DirectX" force feedback implementation as its core and
the Mouse Product must have compatible firmware that locally produces all key
features supported by the then current DirectX 6.0 (Direct-Input) specification.
For non-gaming applications, API will also enable advanced features not
necessarily specified by DirectX as included in the current FEELit API
specification. The device must be able to provide mouse functionality (no force
feedback) when powered by USB only, in low power mode (4.4V, 100 mA) to comply
with the USB Specification at power up.

        Requirement Overview: The Mouse Product must be a high quality, premium
        cursor control peripheral capable of providing accurate positioning data
        and producing realistic force feedback sensations. The product must
        consist of the following subsystems:

        Mouse Handle: Logitech to provide the design. A deadman switch is not
        currently provided from Immersion but may be included by Logitech if it
        proves necessary.

        Base Enclosure/Support: Immersion to provide the basic mouse pad housing
        concept and recommendations. Logitech to provide the industrial design.
        Logitech to do detailed design with input from Immersion. The support
        must carry the mouse loads, both user loads and force feedback loads,
        without introducing excessive friction or binding. The support must
        include a hard stop around the peripheral of the mouse workspace. Range
        of motion provided for the Mouse Product is specified at the end of this
        section.

        Transmission: Immersion to provide a parallel linkage design. The
        transmission will be a five-bar linkage structure that conveys
        mechanical power from actuators to the Mouse Handle.



                                       23
<PAGE>   24
        Actuator: Immersion to provide the full design of custom flat actuators
        (voice coils) optimized for the Mouse Product embodiment. Logitech will
        produce the actuator coils but Immersion will supply the Magnet Assembly
        as a separate component governed by a separate Component Supply
        Agreement.

        Spring Centering: Physical springs are not needed for this product. All
        spring centering for gaming applications will be simulated by the local
        processor.

        Power Electronics: Immersion must provide the initial design. There will
        be an external power source (brick) in the initial product. [****]
        Product will draw non-force feedback power from USB.

        Microprocessor and Interface Electronics: Immersion must provide the
        board design for controller electronics, to be industrialised by
        Logitech. Immersion will supply the FEELit Chip processor under a
        separate OEM agreement, said processor including firmware to create
        local force feedback sensations. Design will be USB high speed
        compatible. It is currently estimated that the COG for the die-shrink
        version of the FEELit Chip in production volumes (100,000 units per
        year) will be [****] or less.

        Sensors: Immersion provides recommendation and design implementation for
        sensors that monitor the motion of the mouse and report such data back
        to the host across USB via the microprocessor. It is currently estimated
        that the COG for the sensing electronics will be less than [****].

        Sensitivity: Mouse to support basic mouse ballistic scaling algorithms
        wherein mouse position sensitivity is varied with velocity of mouse
        movement. [****].

        Embedded Software: Immersion must provide the HEX code. The embedded
        software will be Direct-X and FEELit compatible and USB enabled.
        Logitech will not have access to any parts of the source code (including
        but not limited to the force feedback core) except as provided in
        Section 2.2.1 ("Firmware Source Code"). [****] After the final firmware
        is delivered, Immersion will provide access to several sections of the
        firmware including those related to [****]

        Host Software: Immersion will provide drivers that manage force feedback
        of the device in Windows 98 and NT. The driver will support the
        DirectInput API and the FeelIt API. A custom interface may be needed to
        communicate with existing Logitech MouseWare drivers. This custom
        interface would be developed between Logitech and Immersion. The general
        breakdown of the software should be such that Immersion manages the
        Force Feedback components, and Logitech's MouseWare manages the button
        programmability, wheel support, port management, and sensor and button
        reporting for cursor movement control as well as gaming movement control
        through DirectX.

        Switches and Buttons: The product will support three standard moue
        buttons plus [****], all processed by the FEELit Chip if possible.

        Compliance: The Immersion/Logitech design must comply with 761325-0000
        Rev A Logitech EMI standard. Exceptions to this standard must be duly
        approved by Logitech. GOI-740329-00 Rev B is the current generic
        reference for reliability. Applicable standards are the following:

               Drop: 90 cm

               Light immunity: 100 kLux

               Environmental: -40.. +70C (non Operating, 53 Hours cycle)
                              0C (operating, 8 hours)
                              +40C (operating, 90% RH, 8 hours)
                              +40C (operating, 10% RH, 8 hours)

               Vibration: refer to GOI-740329-00

               Shock: refer to GOI-740329-00

        Product Details: The product must perform as follows:

               Range of Motion: No less than [****]

               Force Output: A minimum of [****] grams (peak)

               Dimensions: The size shall be minimized within the constraints of
               packaging.

               Power Consumption: No more than [****] watts peak.

               Tracking: Allows [****].

        Target Cost: Logitech desires a product with a suggested retail price of
$99 assuming China based labor costs, approximately [****] Logitech margin, and
approximately [****] in nine-level costs. While many of the component costs,
labor costs, and other factors that affect Logitech's ability to hit any given
price target are not related to Immersion's obligations under this contract,
there are currently unknown component costs that do depend upon Immersion's
design. These unknown component costs are the cost of goods for the sensor
electronics and actuator subsystem. At the present time, the preliminary sensor
electronics component costs are estimated at [****] and the preliminary actuator
component costs are estimated at [****]. Based upon the current specification,
Immersion has informed Logitech that it expects that [****] to [****] can be cut
from the combined component costs of the sensor electronics and actuator
subsystem. Note: all costs are based upon the production volume target of
100,000 units per year.
