       to a Problem in the Software, Legato will so notify Reseller.

5.2.7  ACCESS TO INFORMATION. Subject to Reseller's security requirements,
       Reseller will provide Legato with access to and use of all information
       and system facilities reasonably determined necessary by Legato to
       provide timely support pursuant to the terms herein. To the extent
       Reseller's computing system environment permits remote access, Reseller
       shall provide Legato with all required user IDs and passwords so that
       Legato may endeavor to remedy any Problems, in whole or in part, via
       remote system access.

6      ESCALATION PROCEDURE FOR SEVERITY 1 CASES.

6.1    With respect to Severity Level 1 Problems, if the parties have not
       determined a mutually satisfactory Problem Resolution within a reasonable
       timeframe and there is non-arbitrary and non-capricious disagreement
       between the parties as to the appropriate procedure to follow to reach
       such Problem Resolution, then either party may escalate the Problem as
       follows:

6.2    Reseller and Legato will work to ensure that proper resources are brought
       to bear on Escalated problems that are Software related. The parties'
       efforts, will include, where necessary or appropriate as mutually
       determined by the parties, Reseller's and Legato's assignment of
       additional technical support personnel, and establishment of escalation
       specific processes,

       operations and management contacts (the "Escalation Action Plan").

6.3    Each party will designate its Escalation management contact that will be
       available at any time (24 hours a day, 7 days a week). Reseller's
       escalation management contact will contact Legato dispatch for routing to
       the appropriate Legato management contact to develop an action plan. This
       plan will outline the specific steps the parties will take. When both
       parties agree that an Escalated Problem has achieved Problem Resolution,
       the Escalation shall be closed.

6.4    If Reseller has selected the PSAM Option, the Escalation Procedure for
       Severity Level 1 Cases shall be as defined in Section 15.

7      OTHER ERRORS.

7.1    If Legato reasonably believes that an end-user's Problem reported by
       Reseller may not be due to a problem in the Software, Legato will so
       notify Reseller, who then may either: (i) instruct Legato to proceed with
       Problem determination at Reseller's possible expense, as further provided
       below; or (ii) advise Legato that Reseller does not wish the Problem
       pursued at its possible expense, in which case Legato may elect, at its
       sole discretion, to not pursue the Problem without liability therefore.

7.2    If Reseller requests that Legato proceed with Problem determination at
       Reseller's possible expense, and Legato subsequently determines that the
       error was not caused by a Problem in the Software, Reseller shall
       compensate Legato for all work performed in connection with such
       determination on a time and materials basis, plus reasonable related
       expenses incurred therewith, at Legato's then-current professional
       services time and materials rates.

7.3    Reseller shall not be liable for:

7.3.1  Legato's work on problem determination or repair associated with or
       resultant from Problem(s) in the Software;

7.3.2  Work performed by Legato, which was not authorized pursuant to Reseller's
       instruction, as provided in Section 7.1 (i) above;

7.3.3  Work performed by Legato after receipt of Reseller's notice that it no
       longer wishes Legato to work, at Reseller's expense, on a problem that
       Legato previously identified as a problem that may not be caused by the
       Software. Reseller's notice will be effective as of the date such notice
       is actually received by Legato.

8      OWNERSHIP

8.1    RIGHTS OF LEGATO. Reseller acknowledges that Legato provides services to
       other Resellers of Legato and agrees that nothing in this Agreement will
       be deemed or construed to prevent Legato from carrying on such business.

9.1    The term of this Agreement is as specified in Section 2 of Page 1, unless
       terminated earlier as provided in this Section 9. However, if Reseller
       utilizes all the Cases it has paid for prior to the end of the
       anniversary of the Effective Date, and Reseller requires an extension of
       Technical Support under this Agreement, Legato shall prorate the
       remaining months by dividing the amount paid for the Cases indicated on
       Page 1 of this Agreement by 12 and charging Reseller that amount for each
       remaining month until the anniversary date of the Effective Date; and
       Reseller shall issue Legato a purchase order for the prorated amount.

9.2    NON-RENEWAL. Legato shall have the option to not renew this Agreement if,

       classification has not improved to "Compliant."

9.3    TERMINATION OF SOFTWARE SUPPORT. Legato shall have the right not to renew
       Technical Support for any Software by providing written notice of such
       election at least ninety (90) days prior to the termination of such
       support services for that Software, provided that Legato no longer
       generally provides Technical Support for such Software, or, upon renewal,
       no longer provides the specific services previously offered.

9.4    TERMINATION OF RESELLER AGREEMENT. Legato shall have the right to
       terminate this Agreement if Reseller's Reseller Agreement is terminated
       by Legato for cause. If this Agreement is terminated pursuant to this
       Section, then Legato shall refund Reseller a pro-rated amount based on
       the remaining time period or unused Cases, whichever applies.

       implied, statutory, or otherwise, including without limitation any
       implied warranties of merchantability, fitness for a particular purpose,
       and non-infringement. Legato actively solicits RFE's from its Resellers,

       production Software and does not include support of other software
       (device drivers, shell scripts or special programs) or hardware (tape

       of liability of limited remedy, Legato's entire aggregate liability
       arising from or relating to this Agreement, under any legal theory
       (whether in contract, tort, indemnity or otherwise), will be limited to
       the amounts paid by Reseller for the Updates and Technical Support for
       the applicable year.

11.2   LIABILITY ARISING FROM REMOTE ACCESS. To the extent that Reseller suffers
       any damage as a direct result of Legato or Legato's employees or agents
       intentionally committing any wrongful act in connection with the use of
       user ID's and/or passwords to gain remote access to Reseller's computer
       system, Legato will remain liable for damages suffered by Reseller.

12     NON-SOLICITATION


12.1   NON-SOLICITATION. Neither party will, during the Term or any renewal
       hereof, and for one (1) year after its termination, solicit for hire as
       an employee, consultant or otherwise any of the other party's personnel
       who have had direct involvement with the performance of this Agreement,
       without such other party's express written consent.

       ON SITE REPLICATION AND/OR TECHNICAL SUPPORT TERMS AND CONDITIONS

                                     SAMPLE


If Legato is providing On-Site Replication and/or Technical Support personnel at
Reseller's request, the following terms and conditions apply to that
transaction. Unless defined otherwise herein, capitalized terms used in this
Exhibit shall have the same meaning as set forth in the Agreement. For the
purpose of this Exhibit D only, the definition of Technical Support, in addition
to its defined meaning in Section 1 of the Agreement, includes on-site
Replication of the Problem.


1.       ON-SITE TECHNICAL SUPPORT FEES. If Reseller requests Legato to provide
         on-site Technical Support for a Problem at its or its End-User's site,
         the fees for such support are $2500 per day, plus travel and living
         expenses, and Reseller agrees to pay such additional fees by submitting
         to Legato a purchase order or an email of its authorization to proceed
         with the intention to pay.

         The purpose of the On-Site Support is based on CASE NO.: ______________
         reported to Legato by the Reseller.

         Description of Problem to be Resolved:

         On-Site Technical Support fees exclude applicable taxes, and
         travel/living expenses, which will be separately invoiced, and due upon
         receipt.

2.       GENERAL

2.1      CONFIDENTIAL INFORMATION AND OWNERSHIP. In the performance of the
         On-Site Technical Support services, employees of each party may
         receive confidential information and materials of the other
         ("Confidential Information"). Confidential Information includes (i)
         either party's business or financial information and plans; (ii) the
         price, scope, and terms of this Agreement; (iii) any other items
         identified as being confidential by either party. Confidential
         Information will not include information that the receiving party can
         show: (a) is or becomes publicly known or available through no fault of
         the receiving party; (b) was in its possession prior to receipt from
         the disclosing party, as evidenced by business records; (c) was
         lawfully obtained from a third party who has the right to make such
         disclosure; (d) is independently developed as can be shown by
         documentation; or (e) is produced in compliance with applicable law or
         a court order, provided the receiving party first gives the disclosing
         party reasonable notice of such law or order. Both parties agree for
         themselves, their employees, and subcontractors (if applicable) that
         such information will be kept confidential, using the same degree of
         care that each party uses to protect its own confidential information,
         and not disclosed to third parties. It is understood that no patentable
         or copyrighted material, trade secrets, or other intellectual property
         is anticipated to be developed by either party as part of the provision
         of On-Site Technical Support services. Otherwise, the parties will
         execute a separate agreement accordingly.

2.2      LEGATO PROPRIETARY SOFTWARE. Legato may use certain Legato proprietary
         software in performing services. Such items are owned by Legato or its
         suppliers, who will at all times retain all rights, title and interest
         therein. Reseller agrees not to: use such software for any purpose,
         relicense, copy in whole or in part, modify, reverse engineer,
         decompile or disassemble it. Any information gained by such USE will be
         treated as Confidential Information. Upon termination of services,
         Legato will remove such software from your systems or your
         End-User's systems. Reseller agrees to certify in writing to Legato
         that no other copies of such proprietary software remain in its
         possession.

2.3      RELATIONSHIP OF THE PARTIES AND PROJECT RESPONSIBILITIES. In providing
         the On-Site Technical Support services, Legato is an independent
         contractor, and is neither an agent, partner, nor employee of Reseller.
         Legato will determine the manner in which it will perform its services.
         Reseller will provide reasonable access and facilities to Legato, as
         mutually agreeable. Prior to commencement of the On-Site Technical
         Support services, each party will advise the other of its designated
         Technical Contact for the purposes of all notification requirements
         hereunder.
