3.   Crayfish should be aware that the export or re-export of NAC's products and
     services (together, referred to as "products" below) is subject to the
     export controls of the United States as well as Japanese law. Crayfish
     should also be aware that it is prohibited to diffuse any products,
     technical data, or services which violate the laws and management controls
     of the United States. There are no circumstances under which either NAC's
     products or the services using NAC's products may be offered, sold,
     forwarded, exported or re-exported into (or to a national or resident of)
     Cuba, Iran, Iraq, Libya, North Korea, Syria, Sudan or any other country to
     which the United States has embargoed goods. Additionally, Crayfish may not
     export or re-export to countries to which the Bureau of Export
     Administration of the United States or other federal bureaus reserve,
     cancel or deny export permissions. Certain products of NAC may include
     encryption technologies that should not be offered to "governmental
     organization users (as defined below)" outside the United States. Crayfish

     offered to such "governmental organization users." Except for encryption
     listed as "retail qualified" by the export controls of the United States,
     Crayfish may not offer, sell or transfer any products or services that
     include encryption. The term "Governmental organization users" refers to
     the organizations that act as agencies for central or local governmental
     organizations or their departments, or other governmental functions (except
     in the United States and Canada). Such organizations include
     national/governmental research organizations, national/governmental
     companies or independent business bodies which produce or sell products or
     services controlled by the Wassenaar Arrangement Arms List
     (<http://www.wassenaar.org>), and international governmental organizations.
     However, "Governmental organization users" do not include: public
     utilities; banks and banking facilities; means of transportation;
     broadcasting and amusement facility companies; educational facilities;
     private sector medical institutions; retailers and wholesalers; and
     manufacturers that do not produce or sell munitions (products listed on the
     Wassenaar Arrangement Arms List).

ARTICLE 10 COMPENSATION

1.   On condition that a written report be provided immediately, all rights are
     endowed and cooperation is available from Crayfish so that NAC may protect
     Crayfish from any claims made against Crayfish regarding the direct
     infringement of the Japanese patent right, copyright or trademark by NAC's
     license program. NAC will cover the final charge decided by a court on such
     a claim, charges of damage and the fees for the services of a lawyer.
     However, NAC will not be responsible for any charges incurred by such
     actions taken by Crayfish without the prior agreement of NAC. NAC will not
     be held responsible for the actions of Crayfish regarding any claims which
     pertain to (i) alternation of the license program or use of any version
     other than the most recent, or (ii) use of the license program in
     conjunction with equipment, data or programs not provided by NAC, without
     which such infringement could have been avoided. Should the License Program
     become the subject of an infringement claim or should NAC consider that it
     could become the subject of an infringement claim, Crayfish allows NAC to
     take the following actions (not all are listed) at NAC's discretion and
     expense: (i) to allow Crayfish the right to continue selling or using the
     License Program; (ii) to offer amendments or alternate products in order to
     avoid use of the License Program which is the subject of the infringement
     claim; and (iii) to admit Crayfish to return the License Program, if any of
     above measures can not be taken under the appropriate conditions considered
     by NAC. This item regulates only and exclusively relief measures for
     Crayfish, regarding infringement of rights claims made by a third party
     against Crayfish.

2.   On condition that a written report be provided immediately, all rights are
     endowed and cooperation is available from NAC so that Crayfish may protect
     NAC from any claim made against NAC arising from, (i) use of the License
     Program in conjunction with equipment, data or programs not provided by
     NAC, without which such infringement could have been avoided, (ii)
     execution of the designated service (except for the cases
<PAGE>
     caused by (i) above), and/or (iii) faults, false statements and forbearance
     by Crayfish, its executives or employees. Crayfish will be responsible for
     the final charges decided by a court of law regarding such a claim, damages
     and fees for the services of a lawyer.

ARTICLE 11 WARRANTY

1.   NAC only grants warranty to Crayfish with the provision that the License
     Program actually satisfies the specifications shown in the users' manual
     for NAC's end users at the time when the License Program is forwarded to
     Crayfish. If Crayfish should recognize any bugs or failures which may cause
     severe functional problems, and if Crayfish supplies NAC with a written
     report on that matter, NAC shall make an effort to amend such bugs or
     failures immediately without charging Crayfish. Except for the warranty
     regarding infringement as regulated in the previous section, this item
     regulates the only relief measure for Crayfish regarding either expressed
     or implied warranty based on this contract. NAC's warranty and the related
     responsibility are borne by Crayfish and NAC may not extend such warranty
     to any other party. NAC does not warrant that all the bugs or failures are
     amendable.

2.   Except for the warranty relating to Crayfish as stated above, NAC does not
     extend warranty regarding the license program, either expressed or implied,
     and NAC does not warrant a third party other than Crayfish. Except for the
     expressed warranty relating to Crayfish, NAC denies all warrants, either
     expressed or implied, including those related to the nature of the License
     Program and conformity relating to specific purposes.

ARTICLE 12 TECHNICAL SUPPORT

1.   Regarding maintenance, support, operational instructions, problem reports
     and technical advice, Crayfish is responsible, at its own expense, for all
     responses, oral or written, to its end users.

2.   On the assumption that the support fee (as defined in Attachment A) is
     paid, NAC offers only the technical support to Crayfish, the contents of
     which are described in "Standard Support" as defined in Attachment A or in
     "e500 Standard Support" as defined in Attachment C.

ARTICLE 13 DUTY OF CONFIDENTIALITY

1.   Regarding this contract, specific disclosed material or information in
     which either party indicates its confidentiality in written format is
     considered to be confidential information of the concerned party. Such
     material or information is referred to as "confidential information" below
     and includes drawings, computer programming lists, source codes,
     techniques, algorithms, processes, technical information, information
     pertaining to end users, information pertaining to marketing, and others.
     Except for required actions necessary to fulfill the purposes of this
     contract, both parties shall not use the other party's confidential
     information and shall not disclose such confidential information to any
     third party without the prior written consent of the disclosing party. Such
     regulations are not applicable if such information corresponds to one of
     the following: (i) Such confidential information has entered the public
     domain through no fault of the disclosing party; (ii) Such confidential
     information has been disclosed to the third party, without the limitation
     of confidentiality and without violating this contract; (iii) The receiving
     party proves that the information is developed independently either before
     receiving such confidential information or without reference or use of the
     confidential information; and (iv) the disclosure of such confidential
     information is compelled by a decision of a court or applicable law.

2.   Except for as expressly granted in this contract, Crayfish may not create
     copies of the License Program's practicing format program, recreate it,
     reproduce it, disassemble it, decompile it, execute other reverse
     engineering upon it, or translate it into other computer languages.
     Crayfish also may not copy the confidential information in whole or in
     part. Crayfish must conclude an agreement with Crayfish's employees and its
     contractors who may access NAC's confidential information. The
     aforementioned agreement must be more protective than the regulations in
     this contract. The receiving party shall manage such confidential
     information with a management standard that is equal to the one which it
     applies to the management of its own confidential information and business
     secrets, on assumption that such management standard of the receiving party
     maintains appropriate standards.

ARTICLE 14 LIMITATION OF LIABILITY

Under no circumstances and under no legal theory, whether in tort, contract, or
otherwise, shall NAC or its licensor, suppliers and related companies be liable
for any indirect, special, incidental, or consequential damages of any character
including, without limitation, damages for loss of profit, loss of business
opportunities, loss of data, work stoppage or any and all other damages or
losses, even if NAC has been advised of the possibility of such damages. Under
no circumstances, shall NAC, its licensor, suppliers or related companies be
liable for statements or warranty to the third party made by Crayfish, its
employees, agents or any others. Regardless of the other regulations in this
contract, even if damages are caused by NAC's fulfillment or failure, under no
legal theory, whether in tort, contract, or otherwise, in no event will NAC be
liable for any damages in excess of the amount of royalties paid by Crayfish to
NAC in the preceding six months until such liability is undertaken.

ARTICLE 15 TERM AND TERMINATION OF THE CONTRACT

1.   This contract is effective for one year from the date of issue, except in
     the case of termination in accordance with the regulations of this
     contract. This contract will be automatically renewed for one more year
     unless one of the parties provides notice to the other party at least 30
     days prior to the date when the contract ends stating that it has no
     intention to renew the contract, which will be henceforth based on this
     example. Such renewal shall follow regulations and conditions agreed by the
     both parties.
<PAGE>
2.   Regardless of the above item, both parties may terminate this contract in
     the following cases. However, they may not avoid claims for damages to the
     other party.

     (i)   if the other party takes part in illegal business;

     (ii)  if the other party fails to fulfill the obligations defined in this
           contract or if it violates the regulations and fails to compensate
           within 10 days following receipt of a written reminder from the other
           party;

     (iii) if a trustee is appointed to the other party or to its property;

     (iv)  if the other party cannot make payment to the contractor or to the
           third party, or if the other party cannot make payment by the due
           date;

     (v)   if the other party transfers property for the creditor;

     (vi)  if the other party becomes a concerned party of bankruptcy, corporate
           rehabilitation, corporate reorganization, or has an inability to pay
           or action other measures to relieve a debtor.

     Also, NAC may terminate this contract if more than half of the total number
     of Crayfish's issued stocks (or the amount of investment) is held by the
     third party either directly or indirectly (such a case is referred to as
     "shift of controlling right" below). If the contract is terminated due to
     the shift of controlling right, NAC's claim for damages against Crayfish
     cannot be avoided.

3.   If this contract is terminated, Crayfish must stop the sales and sales
     promotion of the designated service/License Program. However, except for
     termination due to failure of Crayfish, on assumption that Crayfish makes
     royalty payments to NAC, C may complete the dealings for those orders
     already received at the time this contract ends. At the time this contract
     ends, a payment period will begin immediately for Crayfish's unpaid debts
     based on this contract. In addition, at the time this contract ends,
     Crayfish must immediately return NAC's confidential information and any
     items offered by NAC, along with all copies made.

4.   Obligations based on Section 13 of this contract continue until either 10
     years after this contract ends or until such confidential information
     enters the public domain, whichever comes first. Sections 6, 7, 10, 11, 13,
     14, 15 and 16 remain in effect even after the termination or expiration of
     this contract.

     Crayfish should be aware that NAC holds the right to receive relief by
     prohibition command as well as relief such as claims for damages either

     controlling rights, or any other effort for transfer is invalid.

3.   Invalidation of a part of the contract

     items.

*    Obtainment of upgraded versions is on the premise of the payment of the fee
     designated by NAC.

2.   Appliance Product

     "WebShield e500 Appliance"

3.   Designated Service

     (name of Crayfish's service, outline)
     If Crayfish changes the contents of the designated service, Crayfish must
     inform NAC and receive permission 30 days prior to actually making any
     changes. NAC will not agree to have its product combined with a designated
     service of a product which is competing with NAC's product.

4.   Annual License Fee

     The Annual license fee is not applicable if Crayfish, in order to execute
     the designated service, offers the scanning offer by purchasing the
     appliance product and connecting it at the network management center of
     Crayfish. However, the amount spent on the purchase of the appliance
     product cannot cover the payment of monthly service use fee.

5.   Royalty Report

     Crayfish must submit to NAC a monthly report that states the number of
     e-mail boxes for which Crayfish has offered the designated service in each
     month and a calculation of the total service usage fee. The deadline for
     such a royalty report is the 20th of each month and the report must be
     submitted by the end of the relevant month. Crayfish must make royalty
     payments based on such reports in accordance with the conditions defined in
     Article 8 of Attachment A. Royalties are calculated based on the
     regulations stated in Article 6 of Attachment A, regardless of the actual
     amount of payments received from the End Users of Crayfish.

6.   Monthly Service Usage Fee

     A unit price for the Monthly Service Usage Fee per e-mail box must be paid
     by Crayfish to NAC as follows. NAC reserves the right to change the annual
     license fee and/or the Monthly Service Usage fee for the following contract
     term by giving Crayfish notice of thirty days prior to the end of the
     existing contract. Crayfish, however, withholds the right to fix a sales
     price for the designated service to its end users which NAC has no right to
     influence at all.

     Service usage fee per e-mail box/month: 70 yen (consumption tax not
     included)
     Service usage fee per domain/month: 1,750 yen (consumption tax
     not included)
     (limited to a maximum of 50 users)

7.   Support Fee

     Crayfish and NAC shall confirm that Crayfish has already paid Yen 2,405,000
     (consumption tax not included) as the support fee for the first contract
     year by bank account transfer to the account designated by NAC. Upon
     renewal of this contract, Crayfish must pay the "amount announced
     separately by NAC to Crayfish" as the support fee for the next contractual
     year, "within thirty days following the end of the contract term".

8.   Payment Condition

     Payment must be made with consumption tax added, within thirty days of the
     last day of each month, by bank account transfer to the account designated
     by NAC.

                           END USER LICENSE AGREEMENT

NOTICE TO ALL USERS: CAREFULLY READ THE FOLLOWING LEGAL AGREEMENT ("AGREEMENT"),
FOR THE LICENSE OF SPECIFIED SOFTWARE ("SOFTWARE") BY NETWORK ASSOCIATES CO.,
LTD. ("NETWORK ASSOCIATES"). BY INSTALLING OR USING THE SOFTWARE, OR CLICK THE
ACCEPT BUTTON, YOU CONSENT TO BE BOUND BY AND BECOME A PARTY TO THIS AGREEMENT
WITH NETWORKS ASSOCIATES CO., LTD). IF YOU DO NOT AGREE TO ALL OF THE TERMS OF
THE AGREEMENT, DO NOT INSTALL NOR USE THE SOFTWARE, OR DO NOT CLICK THE ACCEPT
BUTTON. (IF APPLICABLE, YOU MAY RETURN THE PRODUCT TO THE PLACE OF PURCHASE FOR
A FULL REFUND.)

1.   LICENSE GRANT.

     Subject to the payment of the applicable license fees, and subject to the
     terms and conditions of this Agreement, Network Associates hereby grants to
     you a non-exclusive, non-transferable right to use one copy of the
     specified version of the Software and the accompanying documentation (the
     "Documentation"). You may install one copy of the Software on one computer,
     workstation, personal digital assistant, pager, cellular phone or other
     electronic device for which the Software was designed (each, a "Client
     Device"). If the Software is licensed as a suite or bundle with more than
     one specified Software products, this license applies to all such specified
     Software products, subject to any restrictions or usage terms specified
     individually for any of such Software products on the applicable price list
     or product packaging that apply to any of such Software products
     individually.

     a.   "Use". The Software may not be used on more than one Client Device or
          by more than one user at a time, except as set forth in this Section
          1. The Software is "in use" on a computer when it is loaded into the
          temporary memory or installed into the permanent memory or saved in
          hard disk or other storage device of that Client Device. This license
          authorizes you to make one copy of the Software solely for backup
          purposes, provided that the copy you make contains all of the
          proprietary notices for the Software.

     b.   "Server Use". To the extent such use is specified in the applicable
          price list or product packaging for the Software, you may use the
          Software on a Client Device or a server ("Server") within a multi-user
          or networked environment ("Server Use") or as a Server. A separate
          license is required for each Client Device or "seat" that may connect
          to the Software at any time, regardless of whether such licensed
          Client Devices or seats are connected to or accessed the Software
          concurrently, or are actually using the Software at any particular
          time. Your use of software or hardware that reduces the number of
          Client Devices or seats that connect to the Software directly (e.g.,
          "multiplexing" or "pooling" software or hardware) does not reduce the
          number of licenses required. (Specifically, you must have that number
          of licenses that would equal the number of distinct inputs to the
          multiplexing or pooling software or hardware "front end"). If the
          number of Client Devices or seats that can connect to the Software can
          exceed the number of licenses you have obtained, then you must have a
          reasonable mechanism in place to ensure that your use of the Software
          does not exceed the use limits specified for the license you have
          obtained. This license authorizes you to make one copy of the
          Documentation for each Client Device or seat that is licensed,
          provided that each such copy contains all of the proprietary notices
          for the Documentation.

     c.   "Volume Use". If the Software is licensed with volume license terms
          (by designation of more than one node) specified in the applicable
          product invoicing, "Confirmation Letter of EndUser License" delivered
          to you ("Letter") or product packaging for the Software, you may make,
          use and install as many additional copies of the Software on the
          number of Client Devices as the volume license terms authorize. You
          must have a reasonable mechanism in place to ensure that the number of
          Client Devices on which the Software has been installed does not
          exceed the number of licenses you have obtained. This license
          authorizes you to make one copy of the Documentation for each
          additional copy authorized by the volume license, provided that each
          such copy contains all of the proprietary notices for the
          Documentation.

2.   TERM.

     This Agreement and the Software are effective during the term of license
     specified on product packaging or the Letter. Network Associates may
     terminate this Agreement if you fail to comply with any of the terms and
     conditions described herein. You may terminate this Agreement at any point
     by destroying all copies of the Software and the Documentation (provided
     that license fees are not refunded). When this agreement terminates, you
     must uninstall the Software from hardware and destroy all copies of the
     Software and the Documentation.

3.   UPDATES.

     to "provision of standard support for McAfee Product" as stated elsewhere)
     (collectively "Standard Service"). Standard Service does not apply to the
     license for only current version obtained without term (perpetual license).
     Network Associates warrant neither repair nor solution of defect. Repair is
     done by inserting into future version or repairing manual. Network
     Associates shall have no obligation to provide support in the event of the
     alteration or modification of the Software or the departure from the method
     of use designated by the manual of Network Associates or in the event that
     operating system and hardware on which the Software runs is different from
     the standard specification designed as the Software runs on such operating
     system and hardware.

     international treaty provisions. Network Associates, Inc., Network
