II.  What Now: Next Steps
- -------------------------

     What happens next?
       .   We have the opportunity to broaden our vision, keep growing the
           business and build upon the strength of our combined people and
           resources.
       .   We have no current plans to move our business from Rockville.
       .   Today's announcement should not - and must not - affect how we
           perform our jobs, and it's critical that we all remain focused on
           conducting business as usual.
       .   Delivering on our revenue and profitability goals for each quarter
           and the year is still critically important, as is following through
           on the commitments and promises we made to our customers, partners,
           shareholders and fellow employees.
       .   Both of our companies are committed to providing the same outstanding
           service and support that our customers, partners, investors and other
           constituents have come to expect from us.
       .   You are still the ones who will make it happen. Right Here. Right
           Now.

     Whom do I report to?  What happens to Rockville headquarters?
       .   You will continue to report to your same manager or supervisor -
           today's announcement won't affect that.
       .   While headquarters of the combined company will be in Mountain View,
           CA. Legato has no current plans to move the Rockville office and
           other OTG locations.

     How are we going to put OTG and Legato together?
       .   We expect the transaction to receive the necessary shareholder and
           customary regulatory approvals to close by the end of the second
           quarter of this year.



       .   Integrating our companies will be a gradual process, beginning with
           the formation of an integration team.
       .   With regard to product integration, the team will pay careful
           attention to ensure that our combined product set achieves the best
           results for customers and the combined company.


III.  Benefits / Options/ ESPP
- ------------------------------

     What happens to my current benefits?
       .   Everything stays the same through year-end.
       .   We believe that Legato has excellent benefits. You will learn more
           about Legato benefits over the next few months when the Legato human
           resources department puts out packages to all employees, fully
           explaining the employee benefits you will receive at the combined
           company.

     What happens to my OTG 401K benefits? What about participation?
       .   There will be no changes to your existing 401K benefits because of
           the merger. They are protected under federal law.

     What happens to my OTG stock options? What is the impact on vesting?
       .   Legato will assume all OTG stock options as part of the transaction.
           The merger agreement does not modify any of the vesting or other
           provisions of the option agreement that OTG gave you. In fact, the
           vesting of part of your OTG options may be accelerated at the closing
           of the transaction.

     Which unvested OTG options will be accelerated and to what extent?
       .   Unvested options granted under the 1998 OTG plan accelerate 100% upon
           deal closing. These options for the most part were granted in 1998
           and 1999.
       .   Unvested options granted under the 2000 plan accelerate 50% upon deal
           closing. The options for the most part were granted in 2000 and 2001.
       .   If you have Smart Storage Conversion options, then your unvested
           options will not accelerate any further since they had already been
           50% accelerated upon the Smart Storage merger with OTG.
       .   For example, if you hold the following option grant under the 2000
           plan: 200 shares vested, 600 shares unvested, after merger close your
           unvested options would accelerate 50%, so you would then have 500
           shares vested and 300 shares unvested.
       .   To view your current options status, go to www.aststockplan.com.

           Contact AST Stock Plan customer service at 1-888-980-6456 if you do
           not have a password.

     How will OTG stock options and common stock be converted into Legato
     options?
       .   Each option for OTG stock will be converted into options for 0.6876
           Legato shares and the right to receive $2.50 in cash upon exercise.
           For example, 100 options of OTG stock would be converted into options
           for 68 Legato shares and the right to $250 dollars in cash, as well
           as cash paid for the value of any fractional shares. However, keep in
           mind that your "strike price" will determine your ultimate value.
       .   We plan to put more information and detail about this on the
           intranet.otg.com site in the coming weeks and will let you know when
           we have done so.



     What will happen to the OTG Employee Stock Purchase Plan (ESPP)?
       .   The OTG ESPP will continue until the close of the merger with Legato.
           At the time of the close, the OTG ESPP will purchase OTG stock with
           accumulated ESPP deductions. This stock will be converted into Legato
           stock at the same exchange ratio as other outstanding stock.

IV.  Marketing
- --------------

     Marketing /Branding
       .   We will not be changing our company name, product names, email
           addresses, logos, business cards, website, phone greetings or any
           other corporate materials and practices until after the transaction
           is completed. The exact timing for these actions will be determined
           by the integration team, and many of these changes will not take
           place before the end of the year.

V.  Media, Investor and Analyst Inquiries

       .   It's important as a company that we speak with one voice. Please

           designated spokespeople.

VI.  About Legato
- -----------------

     About Legato
       .   The Legato Corporate Fact Sheet in the orientation pack (and on the
           OTG intranet) that will be provided to all OTG employees is a good
           place to start for a broad overview about the company.
       .   For more detailed information on Legato's management, stock
           performance, customers, partners and products, you can visit the
           investor relations section of Legato's website, which is located at
           www.legato.com.
           --------------
       .   OTG employees will be able to gain access to the Legato employee
           directory as soon as the IT systems are linked up.
       .   Legato uses a variety of methods to communicate with its employees.
           The most common is called AllHome and is an email messaging program
           that is sent to all Legato employees worldwide. In addition, Legato's
           executive management hosts a monthly all employee teleconference as
           well as a series of regional and worldwide sales management and kick
           off meetings. The current plan calls for the integration of OTG and
           Legato systems, which will provide OTG employees with access to a
           range of Legato's communications tools and updates.
