accordance with the procedures specified in the Cisco Quality Plan.
Notwithstanding the foregoing to the contrary, if and when Seller qualifies to
bypass Cisco's incoming inspection requirement pursuant to the Cisco Quality
Plan, Cisco shall have the right to reject any Product which Cisco determines to
be non-operable upon its removal from its original packaging and initial
check-out ("DOA"), whether discovered by Cisco, its subcontractor or its
customer; in any case, Cisco's sole remedy for Product rejection is set forth in
Section 5.2 below.

5.2  Rejection.  If any Product is defective in material or workmanship, or
     ---------
otherwise not in conformity with the applicable Specifications, Cisco shall have

rejection of the affected Product, request correction or replacement of such
Product. Any Product that has been rejected or required to be corrected must be
replaced or corrected by, and at the expense of, the Seller within five (5)
working days of request by Cisco. If, after being requested by Cisco, Seller
fails to replace or correct any defective item within the required time period,
then Cisco shall have the right, at its sole option and in addition to any other
rights or remedies it may have, to replace or correct such Product and charge to
Seller the cost occasioned thereby provided that such repair or replacement cost
shall not exceed 20% of the purchase price. At Cisco's request, Seller shall
provide to Cisco a

correction or replacement of such Product, or demand a credit or refund for the
amount paid Seller for such non-conforming Product.

     -------
shall package and pack all goods in a manner which is (i) in accordance with
good commercial practice then carried out by Seller, (ii) acceptable to common
carriers for shipment at the lowest rate for the particular goods, and (iii) in

design or appearance of any Product purchased hereunder, or to any
Specifications of any Product irrespective of impact on form, fit, or function,
without Cisco's prior written approval.

6.2  Pre-Shipment Testing.  Prior to delivery, Seller shall test all Products in
     --------------------
accordance with the Test Procedure as set forth in Exhibit H, and shall not
                                                   ---------
knowingly ship Products which fail to meet the Specifications. Seller agrees not
to make any changes or modifications to any test process or procedure without
prior written approval from Cisco. At its option Cisco may, from time to time
and with reasonable prior notice, send its quality control personnel to Seller's
factory to observe the testing. In addition, Cisco may, from time to time,
request modifications to Seller's test procedure, where repetitive failure to
meet Specifications has been noted on shipped equipment in accordance with the
Cisco Quality Plan. Seller shall not unreasonably withhold modifications of this
procedure.

6.3  Engineering Change Approval.  Seller shall not make any changes to any
     ---------------------------
production process, or the controlled process parameters or sources, types or
grade classifications of materials used, with respect to any Product without
first obtaining from Cisco an engineering change approval. Within one (1)
working day after learning of any bug or other problem in a Product which may
result or has already resulted in an impact to the installed customer base of
such Product, the discovering party shall notify the other of such problem.
Seller shall submit a request to make a change containing engineering data in
support of the request. Within ten (10) working days of receiving such request,
Cisco shall respond to Seller's request and shall either (i) approve the


                                                                               7

change, (ii) disapprove the change, or (iii) extend the deadline for the
approval or disapproval period for an additional twenty (20) working days.

6.4  Cisco's Engineering Change Request.  When an engineering change is
     ----------------------------------
requested by Cisco, Cisco shall provide Seller all applicable documentation,
specifications and the requested effective date of such engineering change.
Seller shall respond initially within three (3) working days, advising Cisco as
to (i) implementation and the effective date of such change, (ii) associated
costs and effect to on-hand materials, on-order materials and work in process,
and (iii) the impact of the change upon existing Product pricing and shipment
schedules for the entire period for which purchase orders are outstanding, and
whether Seller agrees to such request. Seller shall also identify any materials
issue or process issue that modifies the shipment schedule that was in effect
immediately prior to the engineering change. Where a requested change may create
scrap costs, Seller agrees to stop work in process and/or orders for materials
within twenty-four (24) hours of notification of such change by Cisco. Materials
on-hand or on-order and work in process which has become obsolete as a result of
the engineering change shall be treated in the same manner as termination of a
Product as set forth herein. In such event, Cisco shall issue requisite
documentation and purchase order release changes before Seller shall begin the
change implementation.

free from defects in materials and workmanship for a period of one (1) year from
the date of shipment by Seller (the "Warranty Period"). During the Warranty
Period, Seller shall, at its own expense and risk, repair or replace (at its
option), and return or deliver to the location designated by Cisco within

than an authorized representative of Seller, Cisco or a party authorized jointly
by Seller and Cisco, or to any Products damaged due to accident or act of God or
by any other event reasonably beyond the control of Seller. NO OTHER WARRANTIES
ARE EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES
OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

9.4  Epidemic Product Failure.  For the purposes of this Agreement epidemic
     ------------------------

units whichever is greater, of the then current total installed base of any
Product should fail in substantially the same manner within any time period of
ninety (90) days or if more than five percent (5%), or 150 units whichever is
greater, of the then current total installed base of any Product should fail in
substantially the same manner within any time period of thirty (30) days, in
each case excluding any failures that are attributable to wear and tear if the
affected Products are no longer under warranty. In the case of epidemic failure,
Seller and Cisco shall cooperate to implement the following procedure:

(a)  Cisco shall promptly notify Seller upon discovery of the failure.


                                                                               9

10.  MANUFACTURING RIGHTS
     --------------------

10.1  Cisco's Right to Manufacture.  For the term of this Agreement, subject to
      ----------------------------
Cisco's compliance with all of the terms and conditions hereof, Seller hereby
grants Cisco a worldwide, nonexclusive, nontransferable right and license to
manufacture or have manufactured the Products ("Manufacturing Rights"), which
Cisco may exercise in accordance with this Agreement at any time upon the
occurrence of the following events or circumstances:

(a)  If Seller fails consistently and continuously to supply Cisco with Products
meeting the applicable Specifications in the quantities required in accordance
with Cisco purchase orders as required hereunder. For purposes of this Section,
Seller shall be deemed to have failed consistently in performing its obligations
to supply Products if (i) in any three (3) month period Seller fails to ship at
least seventy percent (70%) of the required quantities of the Product on or
before the ship dates scheduled in accordance with this Agreement or (ii) there
is an epidemic failure of the Products as set forth in Section 9.4 hereunder,
and Seller has failed to rectify each such problem within six (6) months of
receipt of notification.

(b)  If Seller transfers by sale, merger or other working combination of
ownership of or control in a single transaction over more than fifty percent
(50%) of the voting securities or control of Seller to a party identified on
Exhibit N hereto.

(c)  If Seller discontinues manufacturing the Product and does not make a
substitute available to Cisco that the parties mutually agree is equivalent to,
or greater in function than, the Product.

(d)  If Seller is experiencing financial distress and either (i) there has been
an Insolvency Event (as defined in Section 14.3), or, (ii) Seller's independent
auditors have issued a going concern qualification in their opinion for the
Company's most recently completed fiscal year.


                                                                              10

provisions of Sections 10.2 shall apply.

10.2  (a)  Royalty.  Cisco shall pay the Product royalty set forth in Exhibit K.
           -------                                                    ---------

(b)  Audit Rights.  In the event Cisco exercises its Manufacturing Rights as
     ------------
provided hereunder, Cisco agrees to keep and maintain, for a period of two (2)
years after the end of the year to which they pertain, complete and accurate
records of the Products manufactured and distributed by Cisco in order to
calculate and confirm Cisco's royalty obligations hereunder. Upon reasonable
prior notice, Seller shall have the right, exercisable not more than once every
twelve (12) months, to appoint an independent accounting firm reasonably
acceptable to Cisco, at Seller's expense, to examine such books, records and
accounts during Cisco's normal business hours to verify the royalties due by
Cisco to Seller hereunder, subject to such independent accounting firm's
execution of Cisco's standard confidentiality agreement; provided that execution
of such agreement shall not preclude such firm from reporting its results to
Seller. In the event such audit discloses an underpayment or overpayment of
royalties due hereunder, the appropriate party shall promptly remit the amounts
due to the other party.

10.3  Manufacturing Information Escrow.  The parties agree that upon request by
      --------------------------------
Cisco, Seller shall promptly place into an escrow account: (i) the source code
and applicable documentation for the Products (in either electronic media form
or hard copy); (ii) certain applicable manufacturing information ("Manufacturing
Information"); and (iii) any other information required as set forth in
Exhibit L. Cisco shall select the escrow agent (subject to Seller's reasonable
---------
approval), and be responsible for the establishment, administration and cost of
the escrow account. The parties and the escrow agent shall enter into a
Manufacturing Escrow Agreement in the form and substance as set forth in
Exhibit L. Immediately upon termination of this Agreement, all Manufacturing
---------
Information shall be released back to Seller. The Manufacturing Information
shall be released for use by Cisco, subject to the terms and conditions hereof,
only after notice to Seller and only under circumstances in which Cisco would
otherwise be entitled to exercise the Manufacturing Rights as set forth in the
Escrow Agreement. On the first business day of each calendar quarter Seller
shall deposit into escrow any and all updates, enhancements and modifications to
the Manufacturing Information. All Manufacturing Information shall be treated as
Confidential Information of Seller.

provide Cisco such technical support and assistance as Cisco may reasonably
request in connection with the manufacture of the Products.

11.  INDEMNITY
     ---------

11.1  Indemnification by Seller.  Seller shall defend, indemnify and hold
harmless Cisco and its officers, directors, employees, shareholders, customers,
agents, successors and assigns from and against any and all loss, damages,
liabilities, settlements, costs and expenses (including legal expenses and the
expenses of other professionals) as incurred, resulting from or arising out of
any third party claim which alleges that any Product provided to Cisco hereunder
or the use, manufacture, import, service, support, sale, or distribution thereof
infringes upon,


                                                                              11

parties to this Agreement. As a condition to such defense and indemnification,
Cisco will provide Seller with written notice of the claim within ten (10) days
of first learning of the claim and permit Seller to control the defense,
settlement, adjustment or compromise of any such claim. Cisco may employ counsel
at its own expense to assist it with respect to any such claim; provided,
however, that if such counsel is necessary because Seller has not assumed
control, Seller will bear the expense of such counsel. Cisco shall have no
authority to settle any claim on behalf of Seller.

11.2  Seller's Efforts.  If the manufacture, import, service, support,
      ----------------
distribution, use or sale of the Product is enjoined ,becomes the subject of a
claim of infringement, or in Seller's reasonable estimation is likely to become
the subject of such a claim, Seller shall obtain such licenses, or make such
replacements or modifications, as are necessary to the continue the manufacture,
distribution, use or sale of the Product without infringement and in compliance
with the Specifications. If Seller is unable to achieve either of the foregoing
within ninety (90) days after receipt of notice thereof, Seller shall be
entitled to terminate this Agreement without further penalty and shall promptly
refund to Cisco the invoiced purchase price, plus all shipping, storage, and
associated costs, of any Products returned freight collect to Seller which Cisco
is legally prohibited from distributing, selling or using.

11.3  Exceptions to Seller Indemnity.  Seller shall have no obligation under
      ------------------------------
paragraphs 11.1 and 11.2 to the extent any claim of infringement or
misappropriation results from (i) use of a Product in combination with any other
products, if the infringement would not have occurred but for such combination;
(ii) any alteration or modification of a Product not provided by Seller, if the
infringement would not have occurred but for such alteration or modification;
(iii) use of the Product in a way not intended by Seller or not provided for or
described in the applicable technical documentation, if the infringement would
not have occurred but for such use of the Product; (iv) use of a Product after
Seller has requested that such use be discontinued because of an infringement
claim; (v) use of a Product that has been modified or altered pursuant to a
request from Cisco, if the infringement would not have occurred but for such
alteration or modification, or (vii) exercise of Manufacturing Rights by Cisco.
Cisco shall indemnify and hold harmless Seller for any claims for which Seller
is not responsible pursuant to the preceding sentence of this Section.

liable to pay for the Products ordered by Designated Third Parties. All
references in this Agreement to purchases of, purchase orders for, or shipments
of Products by or to Cisco shall mean by or to Cisco or the Designated Third
Parties. For purposes of volume pricing or other terms or conditions dependent
on volume, all purchases of Products by Cisco and Cisco Subcontractors shall be
aggregated for the benefit of Cisco and each Cisco Subcontractor.

16.  MISCELLANEOUS

16.1  Force Majeure.  Neither party shall be liable to the other for delays or
      -------------
failures in performance resulting from causes beyond the reasonable control of

or

(b)  Suspend this Agreement in whole or in part for the duration of the delaying
cause (up to an additional 180 days). Seller shall resume performance under this
Agreement immediately after the delaying cause ceases and, at Cisco's option,
extend the then current term period for a period equivalent to the length of
time the excused delay endured.

or other benefits under or by reason of this Agreement.

16.6  Equitable Relief.  Each party acknowledges that a breach by the other
      ----------------
party of any confidentiality or proprietary rights provision of this Agreement
may cause the non-breaching party irreparable damage, for which the award of
damages would not be adequate compensation. Consequently, the non-breaching
party may institute an action to enjoin the breaching party from any and all
acts in violation of those provisions, which remedy shall be cumulative and not
exclusive, and a party may seek entry of an injunction enjoining any breach or
threatened breach of those provisions, in addition to any other relief to which
the non-breaching party may be entitled at law or in equity.

hereunder, either in whole or in part, whether by operation of law or otherwise,

       may either (a) reject and return the whole lot(s) for replacement or
       repair at the Supplier's expense in accordance with Section 5.1 and 5.2
       of the Agreement, or (b) perform one hundred percent testing and retain
       all conforming Products and return for replace or repair the
       nonconforming Product at the Supplier's expense in accordance with
       Section 5.1 and 5.2 of the Agreement. All rejected/returned lots/Products
       must be shipped as unique lots/Products and not mixed with new material.

4.4    At Cisco's option, the Supplier will provide, at Cisco's U.S. facility,
       field service and/or technical personnel on-site support as required to
       correct defects found during the acceptance test process. Cisco and
       Supplier shall establish response time based on Manufacturing's
       requirements.

       that was previously repaired. Supplier will provide monthly repair
       information in format acceptable to Cisco by serial number which will
       indicate that the Product has been repaired multiple times.

4.7    Product returned for repair that includes a specific failure mode that
       can not be duplicated and passes all manufacturing test, must be
       processed through a more strenuous, documented test process as compared
       to the standard repair test process in order to duplicate failure mode.
       The supplier shall provide monthly repair information by serial number on
       the no problem founds.



                                                                              27

       Monday through Friday, excluding Cisco-observed holidays.

3.     ESCALATION GUIDELINES
       ---------------------

3.1    The following table sets forth the escalation guidelines by which Seller
       shall address customer support problems reported by Cisco and involve its
       management personnel to address such problems. Priority 1 problem
       escalation times are measured in calendar hours, twenty-four (24) hours
       per day, seven (7) days per week. Priority 2, Priority 3, and Priority 4
       escalation times correspond with Business Hours. The Seller manager to
       whom the problem is escalated will take ownership of the problem and
       ensure that updates are provided to the appropriate Cisco personnel.
       Cisco-initiated escalation's will begin at the Technical Support Group
       Leader level and proceed upward. This will allow those most closely
       associated with the support resources to correct any service problems
       quickly.

3.2    It is Cisco's policy to work with its customer to establish the Priority
       for a problem and to accept the customer's determination of the Priority.
       Seller shall accept the Priority designation agreed to by Cisco and
       Cisco's customers and communicated to Seller by Cisco. Seller will work

       -------

4.1    Software Support.  Seller will support any release of Software for a
       ----------------
       period of thirty-six (36) months from the date of Cisco's first
       commercial shipment of that release, meaning that for that time period,
       errors in that release will be corrected either by means of a patch or
       correction to that release. Subject to the prior written approval of the

4.2.1  Maintenance Modifications.  Seller shall provide Cisco, at least thirty
       -------------------------
       (30) days' advance written notification for new releases of maintenance
       modifications. Such modifications shall be approved by Cisco pursuant to
       the engineering change procedures set forth in Section [6.3] of the
       Agreement and shall be suitable for preparation by Cisco as Product for
       distribution to Cisco's customers, at Cisco's discretion. Cisco may
       request that Seller update all of Cisco's customer


                                                                              40

<PAGE>

SonicWALL OEM Agreement


       support documentation and Product inventory to incorporate
       modifications. In addition, if Cisco and Seller reasonably determine
       that a Product or the Product parts must be replaced in the field
       (including without limitation to rectify epidemic failure), Seller
       shall, at a minimum, provide retrofit kits to Cisco at no charge.

4.2.2  Repair Procedure. Seller shall continue to provide repair for Products
       ----------------
       and Product parts after expiration of the Warranty Period until product
       discontinuance. Repaired Products shall have a six (6) month warranty
       from Seller after shipment to Cisco or the remainder of the replaced
       Products warranty, whichever is greater. Repair is defined as repairing
       the part or Product and bringing it up to the current change level.
       Seller shall track Products returned for repair by serial number and
       shall ship repaired parts within five (5) days of receipt. Cisco shall
       pay for transportation of the repaired part back to Cisco. Each part
       shall be individually packaged and shall meet Cisco packaging
       specifications. Seller shall provide quarterly (or as agreed upon) part
       failure reports. The part failure reports shall include, by serial number
       (where possible), each part repaired, and detailed component level
       failure analysis with the determined failure. Seller shall use a 2-day
       carrier or better within the U.S. and 10-day or better internationally
       (if applicable).

4.2.3  Repair Charges: Without Cisco's approval, repair charges (out of
       --------------
       warranty) shall not exceed twenty-five percent (25%) of the agreed
       selling price for such Product to Cisco. In the event that Product repair
       costs are expected to exceed twenty-five percent (25%) of the agreed
       selling price to Cisco, Seller shall immediately contact Cisco by email
       for instructions.

       ----------------------
       Pricing, of the Agreement.


4.2.5  Emergency Part Shipment Procedure. In cases of emergency, as reasonably
       ---------------------------------
       determined by Cisco, Seller shall ship to Cisco available part(s) or a
       Product with overnight delivery to Cisco, freight collect, using Cisco's
       preferred overnight carrier.

4.2.6  Discontinued Products. Seller shall continue to provide support,
       ---------------------
       including spare parts, to Cisco for each discontinued Product for five
       (5) years after the date of such discontinuance or until termination of
       the Agreement, whichever date occurs first.

4.3    Customer Support. Cisco will provide Level 1 Support and Level 2 Support
       ----------------
       in the same manner that it provides such support for its other similar
       products. Seller will provide Level 3 Support as requested by Cisco and
       in accordance with the terms set forth in Exhibit A of this Agreement to
       Cisco by telephone and/or E-mail seven (7) days a week, twenty-four (24)
       hours per day, with a maximum one (1) hour telephone response time for
       all Priority 1 and Priority 2 problems. In the event that diagnostics and
       troubleshooting are required at a customer site, Cisco and Seller will
       provide, at their own expense, the necessary resources for problem
       resolution, provided that if the diagnosed problem is not a problem with
       the Product, Cisco shall reimburse Seller for its time and materials at
       Seller's then standard rate for such services. Cisco shall provide Seller


                                                                              41

<PAGE>

SonicWALL OEM Agreement


       feedback on any Product bug/defect and potential fixes. Seller shall
       use commercially reasonable efforts to resolve a Product bug/defect.

4.4    Call Flow. The typical call flow shall be as follows: Cisco's Customer
       ---------
       Response Center ("CRC") will receive the initial customer call. The CRC
       will open a case and forward to the appropriate Cisco Technical
       Assistance Center ("TAC") for Level 1 support and Level 2 support. In the
       event a Product problem cannot be resolved at this stage, the Product
       problem will be escalated to the appropriate Cisco Development
       Engineering group ("Cisco DE"). If a Product problem still cannot be
       resolved, Cisco DE shall contact Seller's Development Engineering Support
       Group ("Seller DE") for Level 3 support. (See appropriate Cisco and
       Seller contacts in Section 6 of this Exhibit F.) Seller DE may consult
       with Cisco DE if necessary. Seller DE will advise Cisco DE of it progress
       and TAC will close the case when the problem is resolved. The TAC may
       occasionally call Seller's Product Support Team directly for assistance
       in resolving a case involving a Product.

4.5    Support Prioritization and Escalation Guidelines. To ensure that all
       ------------------------------------------------
       Product problems and technical inquiries are reported in a standard
       format, Seller will use and comply with the problem priority definitions
       and escalation guidelines herein pursuant to Section 3.2. Based on the
       priority of a Product problem, Seller will provide to Cisco fixes or
       work-arounds in the following time frames:

              o  Priority 1: Fix or work-around within eight (8) hours of
                 problem report to Seller;

              o  Priority 2: Fix or work-around within two (2) business days
                 of problem report to Seller;

              o  Priority 3: Fix or work-around within two (2) weeks of
                 problem report to Seller;

              o  Priority 4: Fix or work-around within one (1) month of
                 problem report to Seller.

       For Priority 3 or Priority 4 problems, if Seller is unable to meet the
       time frames listed above, the Seller will provide to Cisco within that
       time frame, at a minimum, a plan for addressing the problem.

4.6    Support Documentation. Promptly upon Cisco's written request, Seller will
       ---------------------
       supply Cisco with appropriate technical documentation and resources that
       Cisco reasonably determines to be useful or necessary to perform customer
       support and troubleshooting or to analyze the technical benefits and
       risks of introducing new releases of a Product into Cisco's customer
       base. Such support documentation will include, without limitation: (i)
       Product specifications, (ii) debugging/support tools, and (iii) lists of
       all error messages with explanations as needed and recommended actions.
       Seller will regularly supply Cisco with all release notes or other
       documentation defining the relevant Product information, symptoms,
       solutions or work-arounds for Product problems. Seller will keep accurate
       records of Product bugs/defects and make such reports available to Cisco
       at least quarterly. Seller will maintain an electronic means (e.g., an
       FTP server) through which Cisco can obtain up-to-date information on
       Product bugs/defects, fixes, and code updates. During the term of this
       Agreement, Seller will provide such support to Cisco at no charge.

5.     Training.

       Valley, California, at mutually agreeable times. Training will include
       installation and configuration of Seller's device and necessary
       configuration for CSS 11000 product, including at least one (1) lab
       exercise. Seller shall deliver to Cisco a multi-media version of the
       training, which will be posted on Cisco's internal web-site to enable
       world-wide access for Product training. Any subsequent releases of
       Seller's Product that significantly changes the installation and
       configuration of Seller's Hardware or Software (at Cisco's reasonable
       discretion) will require subsequent training session(s) at the Seller's
       expense. Cisco shall bear all travel expenses for its employees during
       such training. Cisco may use the Seller's Products for internal
       diagnostics, training, and demonstration purposes at no charge.

5.2    Additional Product this training shall be offered, from time to time,
       upon request by Cisco at such time, place and amount as reasonably agreed
       to by Seller and shall also include, if necessary, compatibility issues
       and engineering debug capabilities. All of Seller's reasonable expenses
       in connection with such additional training shall be pre-approved and
       reimbursed by Cisco, consistent with Cisco's standard policies. Such
       additional training shall be offered to Cisco at a fifty percent (50%)
       discount off of Seller's standard end user pricing for support training.

CONDITIONS SET FORTH HEREIN, THE PARTIES AGREE AS FOLLOWS:

1.     Appointment. Cisco and Seller hereby appoint Escrow Agent as the escrow

       this Escrow Agreement; (ii) the Escrow Agent shall not acquire any
       right or interest in any of the Intellectual Property Rights embodied

4.     Releasing Events. The deposited Escrow Materials will be delivered to
       ----------------
       Cisco by Escrow Agent upon the earliest of one of the events set forth in
       Sections 10.1 of the License and Purchase Agreement, the terms of such
       Sections being incorporated herein by reference.

5.     Use of Escrow Materials. Seller hereby grants Cisco a worldwide,
       -----------------------
       nonexclusive, nontransferable, irrevocable right and license to use the
       Escrowed Materials in connection with Cisco's Manufacturing Rights and
       Cisco's continued marketing, distribution and support of the Products
       pursuant to Section 2 of the License and Purchase Agreement (collectively
       "Escrow License Rights"), which Cisco may exercise at any time upon the
       occurrence of any of the events set forth in paragraph 4.

6.     Escrow Release. Subject to the provisions of Sections 7, 8, and 9 below,
       --------------
       Escrow Agent shall be authorized to release the Escrow Materials to Cisco
       upon receiving written authorization from Cisco certifying that Cisco is
       entitled to the Escrow Materials (the "Notice") pursuant to Section 4
       above. Cisco will include specific instructions to the Escrow Agent for
       this delivery.

7.     Counternotice. Within three (3) business days after receipt of the
       -------------
       Notice, Escrow Agent shall deliver to Seller a copy of the Notice and
       shall confirm such delivery in writing to Cisco. If Escrow Agent, within
       five (5) business days after delivery of the Notice by Escrow Agent to
       Seller, does not receive (a) a written statement from Cisco withdrawing
       such notice, or (b) a counternotice from Seller detailing the
       circumstances which it believes indicate that the release conditions
       specified by Cisco did not occur ("Counternotice"), then Escrow Agent
       shall promptly deliver the Escrow Materials to Cisco.

8.     Disputed Notice. If Seller disputes the existence of the conditions upon
       ---------------
       which the Notice is based, then Seller shall, within five (5) business
       days following its receipt of Notice, submit a Counternotice to Escrow
       Agent. If the Counternotice is received by Escrow Agent before the close
       of business on the fifth (5th) business day following receipt of the
       Notice by Seller, then Escrow Agent shall, within three (3) business days
       after receipt of the Counternotice, serve a copy of the Counternotice on
       Cisco and withhold delivery of the Escrow Materials pending receipt of
       (a) a decision evidencing the outcome of the arbitration provided for in
       Section 9 below, or (b) other written instructions signed by both Seller
       and Cisco. Upon receipt of said decision or other instruction, Escrow
       Agent shall deliver a copy of the Escrow Materials only in accordance
       with the decision or instruction.

9.     Arbitration.
       -----------

          (a) Seller and Cisco agree that, if the Counternotice is given by
       Seller pursuant to Section 7 above, then the parties shall submit the
       dispute to expedited binding arbitration in Santa Clara County,
       California, under the Commercial Arbitration Rules of the American
       Arbitration Association (AAA) by one (1) arbitrator appointed in
       accordance with said rules. Judgment on the award rendered by the
       arbitrator may be entered in any court having jurisdiction thereof.
       The sole question before the arbitrator shall be whether there
       existed, at the time Cisco transmitted the Notice to Escrow Agent, the
       conditions permitting release of the Escrow Materials. The parties
       agree that the decision of the arbitrator shall be final and binding
       and that this decision shall be immediately delivered to the parties
       to the arbitration and to Escrow Agent. If the arbitrator finds that
       the Notice was properly given by Cisco, then Escrow


                                                                              55

SonicWALL OEM Agreement


       Agent shall promptly deliver the Escrow Materials to Cisco. If the
       arbitrator finds to the contrary, then Escrow Agent shall not release
       the Escrow Materials. All fees and charges by the American Arbitration
       Association shall be paid by the nonprevailing party in the
       arbitration. Additionally, the prevailing party in any legal action
       brought by one party against the other and arising out of this
       Agreement will be entitled, in addition to any other rights and
       remedies it may have, to reimbursement for its expenses, including
       reasonable attorneys' fees. All costs of the arbitration incurred by
       Escrow Agent, including reasonable attorney's fees and costs shall be
       paid by the party which does not prevail in the arbitration or as
       otherwise agreed to by the Seller and Cisco.

          (b) Except with regard to matters involving equitable remedies, any
       dispute or claim arising out of or in connection with this Escrow
       Agreement will be finally settled by expedited binding arbitration in
       Santa Clara County, California under the rules of the AAA as set forth
       in Section 9(a) above. Notwithstanding the foregoing, the parties may
       apply to any court of competent jurisdiction for injunctive relief
       without breach of this arbitration provision.

10.    Termination. This Escrow Agreement and the escrow established pursuant to
       -----------
       this Escrow Agreement shall terminate upon (a) notice of such termination
       by Cisco, or (b) three (3) years after the termination of the License and
       Purchase Agreement, and all materials comprising the Escrow Materials
       shall thereupon be returned to Seller. Cisco shall notify Escrow Agent
       upon termination of this Escrow Agreement or the License and Purchase
       Agreement.

11.    Notices.
       -------

11.1   No Liability. It is agreed that Escrow Agent will incur no liability for
       ------------
       acting upon any instruction, notice, direction or other document believed
       by it in good faith to be genuine and to have been made, signed, sent or
       presented by the person or persons authorized to perform such act under
       the terms of this Escrow Agreement.

11.2   Delivery. All notices, instructions, deliveries and other communications
       --------

       been given when personally delivered, when sent by facsimile, telex, or

       To Seller:          To the address first set forth above.

       To Cisco:           To the address first set forth above.

       manner specified in this section.


                                                                              56
