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

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

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

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.

be a trademark in its own right, distinct from the other mark.

8.  SUPPORT
    -------

     Seller shall provide the support services described in Exhibit F on the
                                                            ---------

canceled portion of the purchase order, including, only to the extent that any
components, materials and other inventory cannot be used in any of Seller's
non-Cisco products or are in excess of the quantities required for Seller's own
demand forecast: (i) Seller's cost of component inventory for the terminated
portion of the purchase order(s), (ii) Seller's cost of work in process
materials including manufacturing operations completed at the time of
cancellation for the canceled portion of Cisco's purchase order, and (iii)
reasonable cancellation charges incurred by Seller from component suppliers for
the canceled portion of Cisco's purchase order.

     (c) Any claim for cancellation charges for such items must be submitted to
Cisco in writing within thirty (30) days after receipt of Cisco's cancellation
notice. Failure to submit the claim within thirty (30) working days will
constitute a waiver of all claims and a release of all Cisco's liability arising
out of the termination.

     (d) Upon payment of Seller's claim, Cisco shall be entitled to all work and
materials fully paid for. Cisco is not responsible for any other costs or
liability in connection within any cancellation.

     (e) Prior to payment under this Section, Cisco may inspect Supplier's
inventory of canceled Products and audit all relevant documents.

                                                                              36

shall any charge exceed the aggregate price specified in the canceled purchase
order(s) less payments otherwise made or to be made. Any amounts payable for
property lost, damaged, stolen or destroyed prior to delivery to Cisco will be
excluded from amounts otherwise payable to Seller hereunder. THIS EXHIBIT SETS

                  to bring to resolution.

2.     PROBLEM PRIORITIES DEFINITIONS
       ------------------------------

       Problem priorities shall be classified as follows:

2.1    Priority 1: Cisco's customer's production network is down, causing
       ----------
       critical impact to business operations if service is not restored
       quickly. No work around is available. Cisco, Cisco's customer, and Seller
       will commit full time resources around the clock to resolve the
       situation.

2.2    Priority 2: Cisco's customer's production network is severely degraded,
       ----------
       impacting significant aspects of business operations. No work-around is
       available. Cisco, Cisco's customer, and Seller will full time commit
       resources during Business Hours to resolve the situation.

2.3    Priority 3: Cisco's customer's network performance is degraded. Network
       ----------
       functionality is noticeably impaired, but most business operations
       continue.

2.4    Priority 4: Cisco or Cisco's customer requires information or assistance
       ----------
       on Product capabilities, installation, or configuration.

                                                                              38

SonicWALL OEM Agreement

2.5    "Business Hours" means 6:00 a.m. to 6:00 p.m., Pacific Standard Time,
        --------------
       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
       with Cisco according to the processes and procedures contained in this
       Exhibit F.

       -------

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

       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).

       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.

              [***]

[***] Certain information on this page has been omitted and filed separately
with the Securities and Exchange Commission. Confidential treatment has been
requested with respect to the omitted portions.

4.2.4  Prices for Spare Parts: Price for spare parts are reflected in Exhibit A,
       ----------------------
       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.

SonicWALL OEM Agreement

5.1    Seller shall offer, at no cost to Cisco, prior to Seller's first
       commercial shipment of any major Product release and at least annually
       thereafter, eight (8) hours of training at the Cisco's facility in Scotts
       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.

of the need for any adjustment, Seller shall make any quantity adjustments to
Buffer Inventory requested by Cisco. Cisco may, at any time after the Buffer
Inventory has been established, place a purchase order for Products in Buffer
Inventory (an "Expedited Purchase Order"). Expedited Purchase Orders shall
clearly specify that the Products shall be taken only from the Buffer Inventory
and may not cover quantities in excess of required Buffer Inventory. In such
event, Seller shall be obligated to accept the Expedited Purchase Order and upon
receipt thereof, Seller shall (i) draw the requisite number of Products from
Buffer Inventory and (ii) deliver such Products to Cisco on the delivery date
specified in the Expedited Purchase Order. Seller shall not accept Expedited
Purchase Orders from Designated Third Parties unless Cisco has provided written
authorization therefor. Seller shall replenish Buffer Inventory within
forty-five (45) days after any depletion. Cisco reserves the right to cancel the
Buffer Inventory program at any time. Upon cancellation of Buffer Inventory
program or Cisco's election to substitute Product under an order in accordance
with Section 1.2 of this Agreement, Seller will charge Cisco the agreed upon
price in Exhibit A for Product remaining in the Buffer Inventory. Upon
termination of OEM agreement, Cisco will be billed the agreed upon price in
Exhibit A for remaining Product in the Buffer Inventory.

       Sections being incorporated herein by reference.

       --------------
       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.

       -------------
       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

       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

       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

       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

       Agreement.
