                 Subject to Completion, dated September __, 1998

                                 249,999 Shares

                              LEGATO SYSTEMS, INC.

                                  Common Stock

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

         This  Prospectus  relates  to the public  offering,  which is not being
underwritten,  of 249,999  shares (the  "Shares") of Common  Stock,  $0.0001 par
value (the "Common Stock") of Legato Systems,  Inc. (the "Company",  "Legato" or
the "Registrant").

         The Shares may be offered by certain  stockholders  of the Company (the
"Selling Stockholders") from time to time in transactions on the Nasdaq National
Market,  in  privately  negotiated  transactions,  or by a  combination  of such
methods  of sale,  at  fixed  prices  that  may be  changed,  at  market  prices
prevailing  at the time of sale,  at prices  related to such  prevailing  market
prices or at  negotiated  prices.  The  Selling  Stockholders  may  effect  such
transactions  by  selling  the  Shares  to or  through  broker-dealers  and such
broker-dealers may receive compensation in the form of discounts, concessions or
commissions  from the Selling  Stockholders  or the purchasers of the Shares for
whom such  broker-dealers  may act as agent or to whom they sell as principal or
both (which  compensation  to a particular  broker-dealer  might be in excess of
customary commissions). See "Selling Stockholders" and "Plan of Distribution."

         The Company will not receive any of the  proceeds  from the sale of the
Shares by the  Selling  Stockholders.  The  Company  has agreed to bear  certain
expenses  in  connection  with the  registration  and sale of the  Shares  being
offered by the Selling Stockholders.

         The Common  Stock is traded on the  Nasdaq  National  Market  under the
symbol  "LGTO."  Application  has been  made to list the  shares  on the  Nasdaq
National  Market.  On September __, 1998, the closing bid price of the Company's
Common Stock on the Nasdaq National Market was $____ per share.

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

         The  Selling   Stockholders  and  any  broker-dealers  or  agents  that
participate with the Selling  Stockholders in the distribution of the Shares may
be deemed to be  "underwriters"  within  the  meaning  of  Section  2(11) of the
Securities  Act,  and any  commissions  received  by them and any  profit on the
resale  of the  Shares  purchased  by  them  may be  deemed  to be  underwriting
commissions or discounts under the Securities Act.

         No underwriting commissions or discounts will be paid by the Company in
connection  with this  offering.  Estimated  expenses  payable by the Company in
connection with this offering are estimated to be $9,614. The aggregate price of
the Common Stock sold less the aggregate  agents'  commissions and underwriters'
discounts,  if any, and other expenses of issuance and distribution not borne by
the Company. See "Plan of Distribution."

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

         THE COMMON STOCK OFFERED HEREBY INVOLVES A HIGH DEGREE OF RISK.

                          SEE "RISK FACTORS" ON PAGE 8.

applications  and  product  enhancements  and to control  costs;  the  Company's
success in expanding its sales and marketing programs;  technological changes in
the network  storage  management  market;  the mix of sales among the  Company's
channels;  deferrals  of  customer  orders  in  anticipation  of  new  products,
applications or product  enhancements;  changes in Company  strategy;  personnel
changes; and general economic factors.

     The  Company's  future  revenues  are  difficult  to  predict.  The Company
operates with virtually no order backlog because its software products typically
are shipped shortly after orders are received. In addition, the Company does not
recognize revenues on sales to domestic distributors until the products are sold
through to end-users.  As a result,  product license revenues in any quarter are
substantially  dependent  on orders  booked and shipped and on  sell-through  to
end-users in that quarter.  Revenues for any future quarter are not  predictable
with any significant degree of certainty. Product licenses and software services
and support  revenues  are  difficult  to forecast  because the network  storage
management  market is rapidly  evolving  and the  Company's  sales cycle  varies
substantially  from  customer to customer.  The Company has become  increasingly
dependent  upon  the  larger  enterprise   license   transactions  to  corporate
customers,  which often include product license, service and support components.
The Company's  operating  results are sensitive to the timing of such orders and
are subject to  purchasing  cycles and  budgetary  constraints  of the customer,
which are difficult to predict.  Due to the lengthier sales cycle and the larger
size of enterprise license  transactions,  if orders forecasted for a particular
quarter are not realized in that quarter,  the Company's  operating  results for
that  quarter may be adversely  affected.  Royalty  revenues  are  substantially
dependent upon product license sales by OEMs of their products that  incorporate
the  Company's  software.  Accordingly,  royalty  revenues  are subject to OEMs'
product  cycles,  which are also  difficult  to predict.  Royalty  revenues  are
further impacted by fluctuations in licensing activity from  quarter-to-quarter,
because initial license fees generally are non-recurring and recognized upon the
signing of the license  agreement.  The Company's  expense levels are based,  in
part, on its  expectations  as to future  revenues.  If revenue levels are below
expectations,  operating results are likely to be adversely affected. Net income
may  be  disproportionately  affected  by a  reduction  in  revenues  because  a
proportionately  smaller  amount  of the  Company's  expenses  varies  with  its
revenues. As a result, the Company believes that period-to-period comparisons of
its  results of  operations  are not  necessarily  meaningful  and should not be
relied upon as  indications of future  performance.  Due to all of the foregoing
factors,  it is possible that in some future  quarters the  Company's  operating
results may be below the  expectations  of public market analysts and investors.
In such  event,  the  price  of the  Company's  common  stock  would  likely  be
materially adversely affected.

Product Concentration

     The Company currently  derives a substantial  majority of its revenues from
its NetWorker  software products and related  services,  and the Company expects
that  revenues  from  NetWorker  will  continue to account for a majority of the
Company's  revenues  for the  foreseeable  future.  Broad market  acceptance  of
NetWorker is, therefore,  critical to the Company's future success. As a result,
a decline in unit prices of or demand for NetWorker, or failure to achieve broad
market acceptance of NetWorker, as a result of competition, technological change
or otherwise,  would have a material  adverse effect on the business,  operating
results and financial  condition of the Company.  The life cycle of NetWorker is
difficult  to  estimate  due in large  measure  to the recent  emergence  of the
Company's  market,   the  effect  of  new  products,   applications  or  product
enhancements,   technological   changes  in  the  network   storage   management
environment in which NetWorker  operates and future  competition.  The Company's
future financial performance will depend in part on the successful  development,
introduction  and market  acceptance of new products,  applications  and product
enhancements.  There can be no assurance  that the Company  will  continue to be
successful  in  marketing   and   licensing   NetWorker  or  any  new  products,
applications, product enhancements and related services.

Competition

     The network  storage  management  market is intensely  competitive,  highly
fragmented  and  characterized  by  rapidly  changing  technology  and  evolving
standards. Competitors vary in size and in the scope and breadth of the products
and services offered.  The Company's major competitors on the Novell NetWare and
Windows NT platforms include Computer Associates (Cheyenne Software) and Seagate
(Palindrome and Arcada);  on the Sun  Solaris/SunOS  platform  include  Computer
Associates   (Legent/Lachman),   EMC2   (Epoch),   Peripheral   Devices   (Delta
Microsystems),  Spectra Logic and Veritas;  on the AIX platform include IBM; and
on the HP-UX platform  include Hewlett  Packard.  In the future,  as the Company
enters new markets,  the Company expects that such markets will have additional,
market-specific  competitors.  In  addition,  many  of  the  Company's  existing
competitors  are broadening  their platform  coverage.  The Company also expects
increased competition from systems and network management companies,  especially
those that have historically  focused on the mainframe market and are broadening
their focus to include the client/server market. In addition,  because there are
relatively  low barriers to entry in the software  market,  the Company  expects
additional competition from other established and emerging companies.  Increased
competition is likely to result in price  reductions,  reduced gross margins and
loss of  market  share,  any of which  could  materially  adversely  affect  the
Company's business, operating results and financial condition.

     Many of the Company's current and potential  competitors have significantly
greater financial, technical, marketing and other resources than the Company. As
a  result,  they  may be  able  to  respond  more  quickly  to  new or  emerging
technologies  and  changes  in  customer  requirements,  or  to  devote  greater
resources to the development, promotion, sale and support of their products than
the Company. The Company also expects that competition will increase as a result
of future software industry  consolidations,  which have occurred in the network
storage  management  market in the past and are expected to occur in the future.
In addition, current and potential competitors have established or may establish
cooperative  relationships among themselves or with third parties.  Accordingly,
it is possible that new  competitors or alliances  among  competitors may emerge
and rapidly acquire  significant  market share. In addition,  network  operating
system  vendors could  introduce new or upgrade  existing  operating  systems or
environments  that  include  storage  management  functionality  offered  by the
Company's  products,  which could  render the  Company's  products  obsolete and
unmarketable. There can be no assurance that the Company will be able to compete
successfully against current or future competitors or that competitive pressures
faced  by the  Company  will  not  materially  adversely  affect  its  business,
operating results and financial condition.

Dependence on New Software Products; Rapid Technological Change

     The  network  storage   management   market  is   characterized   by  rapid
technological  change,  changing  customer needs,  frequent new software product
introductions  and evolving  industry  standards.  The  introduction of products
embodying new  technologies  and the emergence of new industry  standards  could
render the Company's existing products obsolete and unmarketable.  The Company's
future  success  will  depend  upon its  ability to develop  and  introduce  new
software products  (including new releases,  applications and enhancements) on a
timely  basis  that keep  pace  with  technological  developments  and  emerging
industry  standards  and address  the  increasingly  sophisticated  needs of its
customers.  There can be no  assurance  that the Company will be  successful  in
developing and marketing new products that respond to  technological  changes or
evolving industry standards,  that the Company will not experience  difficulties
that  could  delay or  prevent  the  successful  development,  introduction  and
marketing of these new products,  or that its new products will  adequately meet
the requirements of the marketplace or achieve market acceptance. If the Company
is unable,  for  technological  or other  reasons,  to develop and introduce new
products  in a timely  manner in  response  to  changing  market  conditions  or
customer requirements,  the Company's business,  operating results and financial
condition will be materially adversely affected. The Company currently has plans
to  introduce  and market  several  potential  new  products  in the next twelve
months.  Some of the  Company's  competitors  currently  offer  certain of these
potential new products.  Due to the complexity of client/server software and the
difficulty in gauging the engineering effort required to produce these potential
new products,  such potential new products are subject to significant  technical
risks.  There can be no  assurance  that such  potential  new  products  will be
introduced on a timely basis or at all. In the past, the Company has experienced
delays  in  the  commencement  of  commercial  shipments  of its  new  products,
resulting in customer  frustrations  and delay or loss of product  revenues.  If
potential  new products  are delayed or do not achieve  market  acceptance,  the
Company's business, operating results and financial condition will be materially
adversely  affected.  The Company has also, in the past,  experienced  delays in
purchases of its products by customers  anticipating  the launch of new products
by the  Company.  There can be no assurance  that  material  order  deferrals in
anticipation  of new product  introductions  will not occur,  which could have a
material  adverse  effect upon the  Company's  business,  operating  results and
financial condition.

     Software  products  as complex as those  offered by the Company may contain
undetected  errors or failures  when first  introduced  or as new  versions  are
released.  The Company has in the past discovered  software errors in certain of
its new products after their  introduction  and has  experienced  delays or lost
revenues  during the period  required  to correct  these  errors.  Although  the
Company has not experienced  material  adverse  effects  resulting from any such
errors to date,  there can be no assurance that,  despite testing by the Company
and by current and potential customers, errors will not be found in new products
after  commencement  of commercial  shipments,  resulting in loss of or delay in
market acceptance, which could have a material adverse effect upon the Company's
business, operating results and financial condition.

Risks Associated with Reliance on Enterprise License Transactions; 
     Resellers; Strategy of Expanding OEM Channel

     An integral part of the Company's  strategy is to pursue larger  enterprise
license transactions with corporate  customers.  As there has been an increasing
number of  larger  enterprise  license  transactions,  which  may often  include
product license, service and support components, the Company's operating results
are  sensitive to the timing of such orders.  These  transactions  are typically
difficult to manage and predict. The execution of such larger enterprise license
transactions  typically involves significant technical evaluation and commitment
of capital  and other  resources,  with the delays  frequently  associated  with
customers'  internal  procedures,  including  delays to  approve  large  capital
expenditures,  to implement  the  deployment  of new  technologies  within their
networks,  and to test and accept new  technologies  that affect key operations.
For these and other reasons,  the sales cycle  associated with the completing an
enterprise license transaction is typically lengthy,  generally lasting three to
six months, is subject to a number of significant  risks,  including  customers'
budgetary  constraints  and  internal  acceptance  reviews,  that are beyond the
Company's control, and varies substantially from transaction to transaction. Due
to the lengthy sales cycle and the large size of certain transactions, if orders
forecasted for a specific  transaction for a particular quarter are not realized
in that  quarter,  the  Company's  operating  results  for that  quarter  may be
adversely affected.  There can be no assurance that the Company will continue to
complete or increase the number of such larger enterprise license  transactions,
and the  inability  to do so could  materially  adversely  affect the  Company's
business, operating results and financial condition.

     The Company relies  significantly on its distributors,  systems integrators
and value added  resellers  (collectively,  "resellers")  for the  marketing and
distribution  of its  products.  The  Company's  agreements  with  resellers are
generally  not  exclusive  and in many cases may be  terminated  by either party
without  cause.  Many of the  Company's  resellers  carry product lines that are
competitive  with those of the  Company.  There can be no  assurance  that these
resellers  will give a high priority to the marketing of the Company's  products
(they may, in fact,  give a higher  priority to other  products,  including  the
products  of  competitors)  or that they will  continue  to carry the  Company's
products. Events or occurrences of this nature could materially adversely affect
the Company's business, operating results and financial condition. The Company's
results of operations could also be materially  adversely affected by changes in
reseller inventory strategies, which could occur rapidly, and in many cases, may
not be related to end user demand.  There can be no  assurance  that the Company
will retain any of its current  resellers,  nor can there be any assurance  that
the Company will be successful in recruiting replacement or new organizations to
represent  it. Any such changes in the  Company's  distribution  channels  could
materially  adversely  affect the  Company's  business,  operating  results  and
financial condition.

     The Company's  strategy is also to increase the proportion of the Company's
customers licensed through OEMs. The Company is currently investing, and intends
to continue to invest, resources to develop this channel, which could materially
adversely affect the Company's operating margins. There can be no assurance that
the  Company  will  be  successful  in its  efforts  to  increase  the  revenues
represented by this channel.  The Company is dependent upon its OEMs' ability to
develop new  products,  applications  and product  enhancements  on a timely and
cost-effective  basis  that will meet  changing  customer  needs and  respond to
emerging  industry  standards  and  other  technological  changes.  There  is no
assurance  that the Company's  OEMs will  effectively  meet these  technological
challenges.  These  OEMs  are  not  within  the  control  of  the  Company,  may
incorporate  into their products the technologies of other companies in addition
to those of the Company and are not  obligated  to  purchase  products  from the
Company. In addition,  the Company's OEMs generally have exclusive rights to the
Company's technology on their respective  platforms,  subject to certain minimum
royalty  obligations.  There can be no assurance  that any OEM will  continue to
carry the  Company's  products,  and the  inability to recruit,  or the loss of,
important  OEMs  could  materially  adversely  affect  the  Company's  business,
operating results and financial condition.

International Operations; Risks Associated with International Sales

     The Company  believes  that its  continued  growth and  profitability  will
require  further  expansion  of  its  international   operations.  In  order  to
successfully expand  international  sales, the Company must establish additional
foreign   operations,   hire   additional   personnel  and  recruit   additional
international resellers.  This will require significant management attention and
financial  resources  and  could  materially   adversely  affect  the  Company's
operating  margins.  To the extent  that the  Company is unable to effect  these
additions in a timely manner,  the Company's  growth,  if any, in  international
sales  will be  limited,  and the  Company's  business,  operating  results  and
financial condition could be materially adversely affected.  In addition,  there
can be no  assurance  that the  Company  will be able to  maintain  or  increase
international   market  demand  for  the  Company's   products.   The  Company's
international  sales are currently  denominated in U.S. dollars.  An increase in
the value of the U.S.  dollar  relative  to  foreign  currencies  could make the
Company's products more expensive and,  therefore,  potentially less competitive
in those markets.  In some markets,  localization  of the Company's  products is
essential to achieve market penetration. The Company may incur substantial costs
and experience delays in localizing its products,  and there can be no assurance
that any localized product will ever generate significant revenues. In addition,
the Company relies  significantly  on its  distributors  and other  resellers in
international  sales efforts.  Since these  distributors and other resellers are
not employees of the Company and  typically do not offer the Company's  products
exclusively,  there can be no  assurance  that they will  continue to market the
Company's  products.  Additional  risks inherent in the Company's  international
business   activities   generally  include   unexpected  changes  in  regulatory
requirements,  tariffs and other trade barriers, lack of acceptance of localized
products,  if any, in foreign  countries,  longer  accounts  receivable  payment
cycles,  difficulties in managing international operations,  potentially adverse
tax consequences including restrictions on the repatriation of earnings, and the
burdens  of  complying  with a wide  variety of  foreign  laws.  There can be no
assurance  that such  factors  will not have a  material  adverse  effect on the
Company's future international sales and, consequently,  the Company's business,
operating results and financial condition.

Management of Expanding Operations

     The Company has recently  experienced a period of significant  expansion of
its operations that has placed a significant  strain upon its management systems
and resources.  In addition, the Company has recently hired a significant number
of employees,  and plans to further  increase its total  headcount.  The Company
also plans to expand the geographic  scope of its customer base and  operations.
This expansion has resulted and will continue to result in  substantial  demands
on the Company's management  resources.  From time to time, the Company receives
customer  complaints  about the  timeliness  and  accuracy of customer  support.
Although the Company plans to add customer support personnel in order to address
current  customer  support needs and intends to closely monitor progress in this
area,  there can be no assurance that these efforts will be  successful.  If the
Company's efforts are not successful, the Company's business,  operating results
and financial condition could be materially  adversely  affected.  The Company's
ability to compete effectively and to manage future expansion of its operations,
if any,  will  require the Company to  continue  to improve  its  financial  and
management  controls,  reporting  systems and  procedures  on a timely basis and
expand, train and manage its employee work force. There can be no assurance that
the Company will be able to do so successfully.  The Company's  failure to do so
could have a material  adverse  effect upon the  Company's  business,  operating
results and financial condition.

     In addition,  on August 6, 1998, the Company consummated its acquisition of
Software Moguls, Inc. ("SMI"), a developer of advanced backup-retrieval products
for the Windows NT and UNIX environments  based in Eden Prairie,  Minnesota with
32  employees.  The Company  expects that it will face  numerous  challenges  in
integrating  the  SMI  operations  and  employees  into  the  Company.  If  such
integration is not successful,  the Company's  business,  operating  results and
financial condition could be materially adversely affected.

Dependence Upon Key Personnel

     The Company's future  performance also depends in significant part upon the
continued service of its key technical and senior management personnel,  none of
whom is bound by an  employment  agreement.  The loss of the  services of one or
more of the  Company's  officers  or other key  employees  could have a material
adverse  effect on the  Company's  business,  operating  results  and  financial
condition.  The Company's future success also depends on its continuing  ability
to attract and retain  highly  qualified  technical  and  managerial  personnel.
Competition  for such  personnel is intense,  and there can be no assurance that
the Company can retain its key technical and managerial employees or that it can
attract,  assimilate or retain other highly  qualified  technical and managerial
personnel in the future.

Dependence on Growth in the Network Storage Management Market; 
     General Economic and Market Conditions

     All of the Company's  business is in the network storage management market,
which is still an emerging market.  The Company's  future financial  performance
will  depend in large part on  continued  growth in the number of  organizations
adopting network storage management solutions for their client/server  computing
environments.  There can be no  assurance  that the market for  network  storage
management will continue to grow. If the network storage management market fails
to grow or  grows  more  slowly  than the  Company  currently  anticipates,  the
Company's   business,   operating  results  and  financial  condition  would  be
materially  adversely  affected.  During recent years,  segments of the computer
industry  have  experienced  significant  economic  downturns  characterized  by
decreased product demand, production overcapacity, price erosion, work slowdowns
and layoffs. The Company's  operations may in the future experience  substantial
fluctuations from  period-to-period  as a consequence of such industry patterns,
general economic conditions affecting the timing of orders from major customers,
and other factors  affecting  capital  spending.  There can be no assurance that
such factors will not have a material adverse effect on the Company's  business,
operating results or financial condition.

Dependence on Proprietary Technology; Risks of Infringement

     The Company depends significantly upon proprietary technology.  The Company
relies on a combination of patent,  copyright and trademark laws, trade secrets,
confidentiality procedures and contractual provisions to protect its proprietary
rights.  The Company  seeks to protect  its  software,  documentation  and other
written  materials under patent,  trade secret and copyright laws,  which afford
only limited protection. There can be no assurance that the Company will develop
proprietary products or technologies that are patentable, that any issued patent
will  provide  the  Company  with  any  competitive  advantages  or will  not be
challenged  by third  parties,  or that the  patents  of others  will not have a
material  adverse  effect on the Company's  ability to do business.  Despite the
Company's efforts to protect its proprietary  rights,  unauthorized  parties may
attempt  to  copy  aspects  of the  Company's  products  or to  obtain  and  use
information that the Company regards as proprietary.  Policing  unauthorized use
of the Company's  products is  difficult,  and although the Company is unable to
determine the extent to which piracy of its software  products exists,  software
piracy can be expected to be a persistent  problem.  In  licensing  its products
(other than in enterprise license transactions), the Company relies primarily on
"shrink wrap" licenses that are not signed by licensees,  and,  therefore,  such
licenses  may be  unenforceable  under  the laws of  certain  jurisdictions.  In
addition,  the laws of some  foreign  countries  do not  protect  the  Company's
proprietary  rights to as great an extent as do the laws of the  United  States.
There can be no assurance that the Company's means of protecting its proprietary
rights will be adequate or that the Company's competitors will not independently
develop similar  technology,  duplicate the Company's  products or design around
patents  issued to the  Company  or other  intellectual  property  rights of the
Company.

     There have also been  substantial  amounts of  litigation  in the  software
industry  regarding  intellectual  property rights. The Company has from time to
time received claims that it is infringing third parties'  intellectual property
rights,  and there can be no assurance that third parties will not in the future
claim  infringement  by the Company with respect to current or future  products,
trademarks  or other  proprietary  rights.  The Company  expects  that  software
product  developers will  increasingly be subject to infringement  claims as the
number of products and competitors in the Company's  industry  segment grows and
the functionality of products in different industry segments overlaps.  Any such
claims,  with or  without  merit,  could be  time-consuming,  result  in  costly
litigation,  cause product  shipment delays or require the Company to enter into
royalty or  licensing  agreements.  Such  royalty or  licensing  agreements,  if
required,  may not be  available on terms  acceptable  to the Company or at all,
which  could  have a  material  adverse  effect  upon  the  Company's  business,
operating results and financial condition.

Product Liability

     The  Company's  license  agreements  with its customers  typically  contain
provisions  designed  to limit  the  Company's  exposure  to  potential  product
liability  claims.  In licensing its products (other than in enterprise  license
transactions),  the Company relies  primarily on "shrink wrap" licenses that are
not signed by licensees,  and,  therefore,  such  licenses may be  unenforceable
under the laws of certain jurisdictions. As a result of these and other factors,
the  limitation  of  liability  provisions  contained in the  Company's  license
agreements  may not be effective.  The Company's  products can be used to manage
data  critical  to  organizations,  and,  as a result,  the sale and  support of
products  by the  Company  may entail the risk of product  liability  claims.  A
successful  product  liability  claim  brought  against the Company could have a
material  adverse  effect upon the  Company's  business,  operating  results and
financial condition.

Year 2000 Compliance

     Many currently  installed  computer systems and software products are coded
to accept only two digit entries in the date code field.  These date code fields
will need to accept four digit  entries to  distinguish  21st century dates from
20th century dates. As a result, in less than two years, computer systems and/or
software  used by many  companies  will need to be  upgraded to comply with such
"Year  2000"   requirements.   Systems  that  do  not  properly  recognize  such
information could generate erroneous data or cause a system to fail. Significant
uncertainty  exists in the software  industry  concerning the potential  effects
associated with such compliance.

     The Company has conducted Year 2000 compliance reviews for current versions
of the  Company's  products.  The review  includes  assessment,  implementation,
validation testing and contingency planning. The Company continues to respond to
customer  concerns  about  prior  versions  of  the  Company's   products  on  a
case-by-case basis. Although the Company believes its software products are Year
2000 compliant,  there can be no assurance that the Company's  software products
contain all the  necessary  software  routines  and  programs  for the  accurate
calculation,  display,  storage and manipulation of data involving dates. If the
Company's  software products do not contain all the necessary  software routines
and programs for the accurate calculation,  display, storage and manipulation of
data involving  dates, it would have a material  adverse effect on the Company's
business, operating results and financial condition.

     The  Company  has  tested  software  obtained  from third  parties  that is
incorporated into the Company's products, and is seeking assurances from vendors
that licensed  software is Year 2000  compliant.  Despite testing by the Company
and by current and  potential  customers,  and  assurances  from  developers  of
products  incorporated  into the Company's  products,  such products may contain
undetected errors or defects associated with Year 2000 date functions.  Known or
unknown  errors  or  defects  in our  products  may  result  in delay or loss of
revenue, diversion of development resources, damage to the Company's reputation,
or increased service and warranty costs, any of which could materially adversely
affect the Company's business, operating results, or financial condition.

     The Company does not currently  have any  information  concerning  the Year
2000  compliance  status of our customers.  As is the case with other  similarly
situated software companies,  if our current or future customers fail to achieve
Year 2000 compliance or if they divert  technology  expenditures to address Year
2000 compliance  problems,  the Company's  business,  results of operations,  or
financial condition could be materially adversely affected.

     The Company has  initiated  an  assessment  of material  internal  systems.
Although the Company  believes  the  software  and  hardware it uses  internally
comply with Year 2000 requirements and is not aware of any material  operational
issues or costs  associated  with  preparing  its  internally  used software and
hardware for the Year 2000, there can be no assurances that the Company will not
experience serious,  unanticipated  negative  consequences and/or material costs
caused by undetected  errors or defects in the  technology  used in its internal
systems.  The occurrence of any of the foregoing  could have a material  adverse
effect on the Company's business, operating results or financial condition.

     The Company has funded its Year 2000 compliance  review from operating cash
flows and has not separately  accounted for these costs in the past. The Company
will incur  additional  amounts related to the Year 2000  compliance  review for
administrative  personnel to manage the review,  outside contractor  assistance,
technical   support  for  our  products,   product   engineering   and  customer
satisfaction.  However,  management  does not  anticipate  that the Company will
incur  significant  operating  expenses  or be  required  to invest  heavily  in
computer systems improvements to be Year 2000 compliant.

Possible Volatility of Stock Price

     The trading  price of the  Company's  common stock has been subject to wide
fluctuations.  The trading price of the Company's  common stock could be subject
to wide  fluctuations  in the future in  response  to  quarterly  variations  in
operating results,  announcements of technological  innovations or new products,
applications or product enhancements by the Company or its competitors,  changes
in financial  estimates by securities  analysts and other events or factors.  In
addition,  the stock market has  experienced  volatility  that has  particularly
affected  the  market  prices  of  equity  securities  of many  high  technology
companies and that often has been unrelated to the operating performance of such
companies. These broad market fluctuations may adversely affect the market price
of the Company's common stock.

                                 USE OF PROCEEDS


     The Company  will not receive any  proceeds  from the sale of the shares by
the Selling Stockholders.



<PAGE>


                              SELLING STOCKHOLDERS


         The following table sets forth certain information, as of September __,
1998,  with respect to the number of shares of Common Stock owned by the Selling
Stockholders  and as adjusted  to give effect to the sale of the Shares  offered
hereby.  The Shares are being registered to permit public  secondary  trading of
the Shares,  and the Selling  Stockholders  may offer the Shares for resale from
time to time. See "Plan of Distribution."

         The Shares being offered by the Selling Stockholders were acquired from
the Company in the Company's  acquisition of Software Moguls,  Inc., pursuant to
the  Reorganization  Agreement  on August 6, 1998.  The Common  Stock was issued
pursuant to an exemption from the  registration  requirements  of the Securities
Act.  The  Selling  Stockholders  represented  to the  Company  that  they  were
acquiring  the  Shares  for  investment   and  with  no  present   intention  of
distributing the Shares.

         The Company has filed with the Commission,  under the Securities Act, a
Registration  Statement on Form S-3, of which this Prospectus forms a part, with
respect  to the resale of the  Shares  from time to time on the Nasdaq  National
Market or in  privately-negotiated  transactions.  The Company has agreed to use
commercially  reasonable efforts to keep such Registration  Statement  effective
until the  earlier of such time as (i) all the shares have been sold or (ii) all
the Shares may be sold under Rule 144 of the Securities  Act in any  three-month
period.

         The Shares offered by this  Prospectus may be offered from time to time
by the Selling Stockholders named below:

*    Less than 1%

(1)  Applicable  percentage  ownership is based upon 37,278,126 shares of Common
     Stock  outstanding  on  September  18, 1998 and option  shares  outstanding
     immediately  prior to and  immediately  following  the  completion  of this
     offering.  Beneficial  ownership is determined in accordance with the rules
     of the Securities and Exchange  Commission and generally includes voting or
     investment power with respect to securities,  subject to community property
     laws, where applicable. Shares of Common Stock subject to options currently
     exercisable or exercisable  within 60 days of September 18, 1998 are deemed
     to be beneficially owned by the person holding such options or warrants for
     the purpose of computing  the  percentage  ownership of such person but are
     not treated as  outstanding  for the purpose of  computing  the  percentage
     ownership of any other person. This Registration Statement shall also cover
     any additional  shares of Common Stock which become  issuable in connection
     with the shares registered for sale hereby by reason of any stock dividend,
     stock split, recapitalization or other similar transaction effected without
     the receipt of consideration  which results in an increase in the number of
     the Company's outstanding shares of Common Stock.

                              PLAN OF DISTRIBUTION

         The  Company  is   registering   the  Shares  offered  by  the  Selling
Stockholders hereunder pursuant to contractual  registration rights contained in
the Registration Rights Agreement, dated July 30, 1998, by and among the Company
and the Selling Stockholders (the "Registration Rights Agreement").  The Company
has  filed  with the  Commission,  under  the  Securities  Act,  a  Registration
Statement on Form S-3, of which this  Prospectus  forms a part,  with respect to
the resale of the Shares from time to time as described  below.  The Company has
agreed  to  use  commercially  reasonable  efforts  to  keep  such  Registration
Statement  effective  until the  earlier of such time as (i) all the Shares have
been sold or (ii) all the Shares  may be sold  under Rule 144 of the  Securities
Act in any three-month period.

         The Company will  receive no proceeds  from this  offering.  The Shares
offered  hereby  may be sold by the  Selling  Stockholders  from time to time in
transactions in the  over-the-counter  market, on the Nasdaq National Market, in
privately negotiated transactions,  or by a combination of such methods of sale,
at fixed prices which may be changed, at market prices prevailing at the time of
sale, at prices related to prevailing market prices or at negotiated prices. The
Selling  Stockholders  may effect such  transactions by selling the Shares to or
through broker-dealers,  and such broker-dealers may receive compensation in the
form of discounts,  concessions  or  commissions  from the Selling  Stockholders
and/or the  purchasers  of the Shares  for whom such  broker-dealers  may act as
agents or to whom they sell as principals,  or both (which  compensation as to a
particular broker-dealer might be in excess of customary commissions).

         In order to comply  with the  securities  laws of  certain  states,  if
applicable,  the  Shares  will  be  sold  in  such  jurisdictions  only  through
registered or licensed  brokers or dealers.  In addition,  in certain states the
Shares may not be sold unless they have been registered or qualified for sale in
the applicable  state or an exemption  from the  registration  or  qualification
requirement is available and is complied with.

         The  Selling   Stockholders  and  any  broker-dealers  or  agents  that
participate with the Selling  Stockholders in the distribution of the Shares may
under certain circumstances be deemed to be "underwriters" within the meaning of
the Securities Act, and any commissions received by them and any profit realized
on the resale of the Shares  purchased by them may be deemed to be  underwriting
commissions or discounts under the Securities Act. The Selling  Stockholders may
agree to indemnify such broker-dealers  against certain  liabilities,  including
liabilities under Securities Act.

         Any  broker-dealer  participating  in such  transactions  as agent  may
receive commissions from the Selling  Stockholders (and, if it acts as agent for
the purchase of such Shares, from such purchaser). Broker-dealers may agree with
the Selling  Stockholders  to sell a specified  number of Shares at a stipulated
price per share,  and,  to the extent  such a  broker-dealer  is unable to do so
acting as agent for the  Selling  Stockholders,  to purchase  as  principal  any
unsold  Shares.  Brokers-dealers  who acquire Shares as principal may thereafter
resell such Shares from time to time in transactions  (which may involve crosses
and  block  transactions  and  which  may  involve  sales to and  through  other
broker-dealers,  including  transactions of the nature  described  above) in the
over-the-counter  market, on the Nasdaq National Market, in privately negotiated
transactions,  or by a combination of such methods of sale, at fixed prices that
may be  changed,  at market  prices  prevailing  at the time of sale,  at prices
related  to such  prevailing  market  prices  or at  negotiated  prices,  and in
connection  with such resales may pay to or receive from the  purchasers of such
Shares commissions computed as described above.

         Under applicable  rules and regulations  under the 1934 Act, any person
engaged  in the  distribution  of the Shares  may not  simultaneously  engage in
market making  activities  with respect to the Common Stock of the Company for a
period of two business days prior to the commencement of such  distribution.  In
addition and without limiting the foregoing,  the Selling  Stockholders  will be
subject to applicable  provisions of the 1934 Act and the rules and  regulations
thereunder,   including,  without  limitation,  Rules  10b-6  and  10b-7,  which
provisions  may  limit  the  timing  of  purchases  and  sales of  shares of the
Company's Common Stock by the Selling Stockholders.

         The Selling  Stockholders  will pay all  commissions and other expenses
associated  with the sale of Shares by them. The Shares offered hereby are being
registered  pursuant  to  contractual  obligations  of  the  Company  under  the
Registration  Rights  Agreement,  and the  Company  has  agreed to bear  certain
expenses  in  connection  with the  registration  and sale of the  Shares  being
offered by the Selling  Stockholders.  The Company has not made any underwriting
arrangements with respect to the sale of Shares offered hereby.

         The legality of the  securities  offered hereby will be passed upon for

Item 15.  Indemnification of Officers and Directors.

         Section 145 of the Delaware General Corporation law ("DGCL") empowers a
Delaware  corporation  to indemnify any persons who are, or are threatened to be
made,  parties to any  threatened,  pending or completed  legal action,  suit or
proceedings,  whether civil,  criminal,  administrative or investigative  (other
than action by or in the right of such corporation),  by reason of the fact that
such person was an officer or director of such corporation, or is or was serving
at the request of such corporation as a director,  officer, employee or agent of
another corporation or enterprise. The indemnity may include expenses (including
attorneys' fees),  judgments,  fines and amounts paid in settlement actually and
reasonably  incurred  by such person in  connection  with such  action,  suit or
proceeding,  provided that such officer or director acted in good faith and in a
manner he reasonably  believed to be in or not opposed to the corporation's best
interests, and, for criminal proceedings, had no reasonable cause to believe his
conduct was illegal. A Delaware corporation may indemnify officers and directors
in an action by or in the right of the  corporation  under the same  conditions,
except that no  indemnification  is permitted  without judicial  approval if the
officer  or  director  is  adjudged  to be  liable  to  the  corporation  in the
performance  of his duty.  Where an officer or  director  is  successful  on the
merits or  otherwise  in the  defense  of any  action  referred  to  above,  the
corporation  must  indemnify  him against  the  expenses  which such  officer or
director actually and reasonably incurred.

         In accordance with the DGCL, the Company's Certificate of Incorporation
("Certificate")  contains a provision  to limit the  personal  liability  of the
directors of the Company for  violations of their  fiduciary duty as a director.
This  provision  eliminates  each  director's  liability  to the  Company or its
stockholders  for monetary  damages  except (i) for any breach of the director's
duty of loyalty to the Company or its  stockholders,  (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 174 of the DGCL providing for liability of directors
for unlawful payment of dividends or unlawful stock purchases or redemptions, or
(iv) for any  transaction  from which a director  derived an  improper  personal
benefit.  The effect of this provision is to eliminate the personal liability of
directors for monetary damages for actions involving a breach of their fiduciary
duty of care, including any such actions involving gross negligence.

         Article XI of the Company's  Certificate and Article VII,  Section 6 of
the Company's Bylaws provide for  indemnification  of the officers and directors
of the Company to the fullest extent permitted by applicable law.

         The Company  has  entered  into  indemnification  agreements  with each
director and executive officer which provide  indemnification  to such directors
and executive  officers under certain  circumstances for acts or omissions which
may not be covered by directors' and officers' liability insurance.

Item 17.  Undertakings.

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective  amendment to this Registration  Statement:  (i) to include any
prospectus  required by section  10(a)(3) of the Securities Act; (ii) to reflect
in the  prospectus  any facts or events  arising after the effective date of the
Registration  Statement (or the most recent  post-effective  amendment  thereof)
which,  individually or in the aggregate,  represent a fundamental change in the
information set forth in the  Registration  Statement;  and (iii) to include any
material  information  with respect to the plan of  distribution  not previously
disclosed  in  the  Registration  Statement  or  any  material  change  to  such
information in the Registration Statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant  pursuant to the provisions  described in Item 15, or otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission  such  indemnification  is against  public policy as expressed in the
Securities Act and is, therefore,  unenforceable.  In the event that a claim for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  Registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

         The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
1934 Act (and,  where  applicable,  each  filing of an employee  benefit  plan's
annual report pursuant to Section 15(d) of the 1934 Act) that is incorporated by
reference in the Registration Statement shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

         For purposes of determining any liability under the Securities Act, the
information  omitted  from  the  form  of  prospectus  filed  as  part  of  this
Registration  Statement  in reliance  upon Rule 430A and  contained in a form of
prospectus  filed by the Registrant  pursuant to Rule 424(b)(1) or (4) or 497(h)
under  the  Securities  Act  shall  be  deemed  to be part of this  Registration
Statement as of the time it was declared effective.

                      AGREEMENT AND PLAN OF REORGANIZATION



                  This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is
made and entered into as of July 30, 1998, by and among Legato Systems,  Inc., a
Delaware  corporation   ("Acquiror"),   Aspen  Acquisition  Corp.,  a  Minnesota
corporation  ("Merger  Sub"),  Software  Moguls,  Inc., a Minnesota  corporation
("Target"), Sunil Khadilkar as "Shareholders'  Representative," Louis C. Cole as
"Escrow Agent" and each of the  undersigned  stockholders  of the Target (each a
"Signing Stockholder" and, collectively,  the "Signing  Stockholders").  Certain
other capitalized terms used in this Agreement are as defined herein.

                                    RECITALS

                  A. The Boards of Directors of Target,  Acquiror and Merger Sub
believe  it is in the best  interests  of  their  respective  companies  and the
shareholders  and  stockholders  of their  respective  companies that Target and
Merger Sub combine into a single company through the statutory  merger of Merger
Sub with and into  Target  (the  "Merger")  and, in  furtherance  thereof,  have
approved the Merger.

                  B.  Pursuant  to  the  Merger,   among  other   things,   each
outstanding  share of capital  stock of Target,  no par value  ("Target  Capital
Stock"), shall be converted into shares of common stock of Acquiror,  $.0001 par
value ("Acquiror Common Stock"), at the rate set forth herein.

                  C.  Target,  Acquiror  and Merger  Sub desire to make  certain
representations  and  warranties  and other  agreements in  connection  with the
Merger.

                  D. The parties intend, by executing this Agreement, to adopt a
plan of reorganization within the meaning of Section 368 of the Internal Revenue
Code of 1986, as amended (the  "Code"),  and to cause the Merger to qualify as a
reorganization under the provisions of Sections 368(a)(1)(A) and 368(a)(2)(E) of
the Code.

                  E. The parties  intend for the Merger to be accounted for as a
pooling of interests.

                  F.  Concurrent  with the execution of this Agreement and as an
inducement to Acquiror to enter into this  Agreement,  all of the Affiliates (as
defined herein) of Target are delivering to Acquiror irrevocable proxies to vote
the shares of Target's  Common Stock owned by such persons to approve the Merger
and against any competing proposals.

                  NOW,   THEREFORE,   in  consideration  of  the  covenants  and
representations set forth herein, and for other good and valuable consideration,
the parties agree as follows:


                                    ARTICLE I

                                   THE MERGER

     1.1 The  Merger.  At the  Effective  Time (as  defined in Section  1.2) and
subject to and upon the terms and conditions of this Agreement,  the Articles of
Merger  attached  hereto  as  Exhibit  A (the  "Articles  of  Merger")  and  the
applicable  provisions of the Minnesota  Business  Corporation  Act  ("Minnesota
Law"),  Merger Sub shall be merged with and into Target,  the separate corporate
existence of Merger Sub shall cease and Target shall  continue as the  surviving
corporation. Target as the surviving corporation after the Merger is hereinafter
sometimes referred to as the "Surviving Corporation."

     1.2 Closing;  Effective Time. The closing of the transactions  contemplated
hereby  (the  "Closing")  shall  take  place as soon as  practicable  after  the
satisfaction  or waiver of each of the conditions set forth in Article VI hereof
or at such other time as the parties hereto agree (the date on which the Closing
shall occur, the "Closing Date"). The Closing shall take place at the offices of
Gunderson Dettmer Stough Villeneuve Franklin & Hachigian,  LLP, 155 Constitution
Drive,  Menlo Park,  California  94025, or at such other location as the parties
hereto agree.  On the Closing Date, the parties hereto shall cause the Merger to
be  consummated  by filing the  Articles of Merger,  together  with the required
officers'  certificates,  with the Secretary of State of the State of Minnesota,
in accordance  with the relevant  provisions of Minnesota Law (the time and date
of  such  filing  being  the  "Effective   Time"  and  the   "Effective   Date,"
respectively).  

     1.3 Effect of the Merger.  At the Effective  Time, the effect of the Merger
shall  be as  provided  in  this  Agreement,  the  Articles  of  Merger  and the
applicable  provisions of Minnesota Law.  Without limiting the generality of the
foregoing, and subject thereto, at the Effective Time, all the property, rights,
privileges,  powers  and  franchises  of  Target  shall  vest  in the  Surviving
Corporation,  and all debts,  liabilities  and duties of Target shall become the
debts,  liabilities and duties of the Surviving Corporation.  

     1.4 Certificate of Incorporation; Bylaws.

     (a) At the Effective Time, the Articles of  Incorporation of Merger Sub, as
in effect  immediately  prior to the  Effective  Time,  shall be the Articles of
Incorporation of the Surviving  Corporation until thereafter amended as provided
by Minnesota Law and such Certificate of Incorporation;  provided, however, that
Article I of the Articles of Incorporation  shall be amended to read as follows:
"The name of the corporation is Software Moguls, Inc."

     (b) The  Bylaws  of  Merger  Sub,  as in  effect  immediately  prior to the
Effective  Time,  shall  be  the  Bylaws  of  the  Surviving  Corporation  until
thereafter  amended.  

     1.5 Directors and Officers.  At the Effective Time, the directors of Merger
Sub  immediately  prior to the  Effective  Time  shall be the  directors  of the
Surviving Corporation,  to hold office until such time as such directors resign,
are removed or their  respective  successors  are duly elected or appointed  and
qualified.  The officers of Merger Sub  immediately  prior to the Effective Time
shall be the officers of the  Surviving  Corporation,  to hold office until such
time as such officers  resign,  are removed or their  respective  successors are
duly elected or appointed and qualified.

     1.6 Effect on Capital Stock. By virtue of the Merger and without any action
on the part of  Acquiror,  Merger Sub,  Target or the holders of any of Target's
securities: 

     (a)  Conversion of Target  Capital  Stock.  The maximum number of shares of
Acquiror  Common Stock to be issued or reserved for issuance in exchange for the
acquisition by Acquiror of all outstanding Target Capital Stock shall be 250,000
shares  (the "Total  Acquiror  Shares"),  reduced as a result of any  Dissenting
Shares (as defined below).  No adjustment  shall be made in the number of shares
of Acquiror Common Stock issued in the Merger as a result of (x) any increase or
decrease in the market  price of Acquiror  Common  Stock prior to the  Effective
Time or (y) any cash  proceeds  received  by Target  from the date hereof to the
Closing  Date  pursuant to the  exercise  of  currently  outstanding  options to
purchase shares of Target Common Stock ("Target Options").  Subject to the terms
and  conditions of this Agreement and the Articles of Merger as of the Effective
Time,  by virtue of the Merger and  without any action on the part of the holder
of any shares of Target  Capital  Stock,  at the Effective  Time,  each share of
Target Common Stock issued and  outstanding  immediately  prior to the Effective
Time (other than shares to be cancelled  pursuant to Section  1.6(b) and shares,
if any,  held by persons  who have not voted such  shares  for  approval  of the
Merger and with respect to which such persons shall become  entitled to exercise
dissenters'  rights in accordance with the Minnesota  Business  Corporation Act,
Sections  302A.471 and 302A.473  ("Dissenting  Shares"))  shall be converted and
exchanged  for such  number  of  shares  of  Acquiror  Common  Stock as shall be
determined  in  accordance  with  item (i) of  Exhibit B hereof  (the  "Exchange
Ratio").

     (b)  Cancellation  of Target Capital Stock Owned by Acquiror or Target.  At
the Effective  Time, all shares of Target Capital Stock that are owned by Target
as treasury  stock,  each share of Target Capital Stock owned by Acquiror or any
direct or indirect wholly owned subsidiary of Acquiror or of Target  immediately
prior to the  Effective  Time shall be  canceled  and  extinguished  without any
conversion thereof.

     (c)  Capital  Stock of Merger  Sub. At the  Effective  Time,  each share of
Common Stock, .0001 par value, of Merger Sub ("Merger Sub Common Stock"), issued
and outstanding  immediately prior to the Effective Time shall be converted into
and  exchanged for one validly  issued,  fully paid and  nonassessable  share of
Common  Stock,  .0001  par  value,  of the  Surviving  Corporation.  Each  stock
certificate of Merger Sub evidencing ownership of any such shares shall continue
to  evidence  ownership  of  such  shares  of  capital  stock  of the  Surviving
Corporation.

     (d) Adjustments to Exchange Ratio.  The Exchange Ratio shall be adjusted to
reflect  fully the effect of any stock  split,  reverse  split,  stock  dividend
(including any dividend or distribution of securities  convertible into Acquiror
Common Stock or Target Capital Stock), reorganization, recapitalization or other
like  change with  respect to  Acquiror  Common  Stock or Target  Capital  Stock
occurring after the date hereof and prior to the Effective Time.

     (e)  Fractional  Shares.  No fraction of a share of  Acquiror  Common Stock
will be issued,  but in lieu  thereof  each  holder of shares of Target  Capital
Stock who would  otherwise  be  entitled  to a fraction  of a share of  Acquiror
Common Stock (after  aggregating all fractional  shares of Acquiror Common Stock
to be received by such holder)  shall  receive  from  Acquiror an amount of cash
(rounded to the nearest  whole cent) equal to the product of (i) such  fraction,
multiplied by (ii) the Closing  Price.  

     (f) Dissenters'  Rights.  Any Dissenting Shares shall not be converted into
Acquiror  Common Stock but shall instead be converted  into the right to receive
such  consideration  as may  be  determined  to be  due  with  respect  to  such
Dissenting Shares pursuant to Minnesota Law. Target agrees that, except with the
prior written  consent of Acquiror,  or as required under Minnesota Law, it will
not voluntarily  make any payment with respect to, or settle or offer to settle,
any  such  purchase  demand.  Each  holder  of  Dissenting  Shares  ("Dissenting
Shareholder") who, pursuant to the provisions of Minnesota law, becomes entitled
to payment of the fair value for shares of Target  Capital  Stock shall  receive
payment  therefor (but only after the value therefor shall have been agreed upon
or finally  determined  pursuant to such  provisions).  If, after the  Effective
Time,  any  Dissenting  Shares  shall lose their  status as  Dissenting  Shares,
Acquiror  shall  issue  and  deliver,  upon  surrender  by such  shareholder  of
certificate or  certificates  representing  shares of Target Capital Stock,  the
number  of shares of  Acquiror  Common  Stock to which  such  shareholder  would
otherwise be entitled under this Section 1.6 and the Articles of Merger less the
number  of  shares  allocable  to such  shareholder  that  have  been or will be
deposited  in the Escrow  Fund (as  defined  below) in respect of such shares of
Acquiror Common Stock pursuant to Section 1.7 and Article VIII hereof.

     1.7 Surrender of Certificates.

     (a)  Exchange  Agent.  Harris  Trust and Savings Bank shall act as exchange
agent (the "Exchange Agent") in the Merger.

     (b) Acquiror to Provide Common Stock.  Promptly  after the Effective  Time,
Acquiror  shall make  available to the Exchange Agent for exchange in accordance
with this Article I, through such  reasonable  procedures as Acquiror may adopt,
the shares of Acquiror  Common  Stock  issuable  pursuant  to Section  1.6(a) in
exchange for shares of Target Capital Stock outstanding immediately prior to the
Effective  Time  less the  number  of  shares  of  Acquiror  Common  Stock to be
deposited into an escrow fund (the "Escrow Fund")  pursuant to the  requirements
of Article VIII hereof. 

     (c) Exchange  Procedures.  Promptly after the Effective Time, the Surviving
Corporation  shall cause to be mailed to each holder of record of a  certificate
or certificates  (the  "Certificates")  which immediately prior to the Effective
Time represented  outstanding  shares of Target Capital Stock, whose shares were
converted into the right to receive shares of Acquiror Common Stock (and cash in
lieu of fractional  shares) pursuant to Section 1.6, (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the  Certificates  shall pass,  only upon receipt of the  Certificates by the
Exchange  Agent,  and shall be in such form and have such  other  provisions  as
Acquiror may reasonably  specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for certificates  representing  shares
of Acquiror Common Stock (and cash in lieu of fractional shares). Upon surrender
of a Certificate  for  cancellation to the Exchange Agent or to such other agent
or  agents  as may be  appointed  by  Acquiror,  together  with  such  letter of
transmittal,  duly  completed  and  validly  executed  in  accordance  with  the
instructions  thereto,  the  holder of such  Certificate  shall be  entitled  to
receive in  exchange  therefor a  certificate  representing  the number of whole
shares of Acquiror  Common  Stock less the number of shares of  Acquiror  Common
Stock to be deposited  in the Escrow Fund on such  holder's  behalf  pursuant to
Article VIII hereof and payment in lieu of  fractional  shares which such holder
has the right to  receive  pursuant  to  Section  1.6,  and the  Certificate  so
surrendered shall forthwith be canceled. Until so surrendered,  each outstanding
Certificate  that,  prior to the Effective  Time,  represented  shares of Target
Capital  Stock  will be  deemed  from and  after  the  Effective  Time,  for all
corporate  purposes,  other  than the  payment of  dividends,  to  evidence  the
ownership of the number of full shares of Acquiror  Common Stock into which such
shares of Target  Capital  Stock shall have been so  converted  and the right to
receive an amount in cash in lieu of the  issuance of any  fractional  shares in
accordance  with Section 1.6. As soon as practicable  after the Effective  Time,
and  subject to and in  accordance  with the  provisions  of Section 8.3 hereof,
Acquiror  shall cause to be delivered to the Escrow Agent (as defined in Section
8.3 hereof) a certificate or certificates  representing ten percent (10%) of the
Total Acquiror  Shares which shall be registered in the name of the Escrow Agent
as nominee for the holders of  Certificates  cancelled  pursuant to this Section
1.7. Such shares shall be  beneficially  owned by such holders and shall be held
in escrow and shall be available to compensate  Acquiror for certain  damages as
provided in Article VIII. To the extent not used for such purposes,  such shares
shall be released, all as provided in Article VIII hereof.

     (d) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions with respect to Acquiror Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Acquiror  Common Stock  represented  thereby  until the
holder of record of such  Certificate  surrenders such  Certificate.  Subject to
applicable law, following surrender of any such Certificate, there shall be paid
to the record holder of the certificates  representing  whole shares of Acquiror
Common Stock issued in exchange therefor,  without interest, at the time of such
surrender, the amount of any such dividends or other distributions with a record
date after the Effective Time which would have been previously  payable (but for
the  provisions of this Section  1.7(d)) with respect to such shares of Acquiror
Common Stock.

     (e)  Transfers  of  Ownership.  If any  certificate  for shares of Acquiror
Common Stock is to be issued in a name other than that in which the  Certificate
surrendered in exchange  therefor is registered,  it shall be a condition of the
issuance  thereof that the  Certificate so surrendered is properly  endorsed and
otherwise  in proper  form for  transfer  and that the  person  requesting  such
exchange  will have paid to Acquiror or any agent  designated by it any transfer
or other taxes required by reason of the issuance of a certificate for shares of
Acquiror  Common Stock in any name other than that of the  registered  holder of
the Certificate  surrendered,  or established to the satisfaction of Acquiror or
any agent designated by it that such tax has been paid or is not payable.

     (f) No Liability.  Notwithstanding anything to the contrary in this Section
1.7, none of the Exchange Agent,  the Surviving  Corporation or any party hereto
shall be liable to any person for any amount  properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.

     (g) Dissenting  Shares. The provisions of this Section 1.7 shall also apply
to Dissenting Shares that lose their status as such, except that the obligations
of Acquiror  under this  Section 1.7 shall  commence on the date of loss of such
status and the holder of such  shares  shall be  entitled to receive in exchange
for such  shares the  number of shares of  Acquiror  Common  Stock to which such
holder is entitled pursuant to Section 1.6 hereof.

     1.8 No Further  Ownership  Rights in Target  Capital  Stock.  All shares of
Acquiror Common Stock issued upon the surrender for exchange of shares of Target
Capital Stock in accordance  with the terms hereof  (including  any cash paid in
lieu of  fractional  shares)  shall  be  deemed  to  have  been  issued  in full
satisfaction  of all rights  pertaining to such shares of Target  Capital Stock,
and there shall be no further  registration  of  transfers on the records of the
Surviving  Corporation of shares of Target Capital Stock which were  outstanding
immediately  prior  to  the  Effective  Time.  If,  after  the  Effective  Time,
Certificates  are presented to the Surviving  Corporation  for any reason,  they
shall be canceled and exchanged as provided in this Article I.

     1.9 Lost, Stolen or Destroyed  Certificates.  In the event any Certificates
shall have been lost,  stolen or  destroyed,  the Exchange  Agent shall issue in
exchange for such lost, stolen or destroyed Certificates,  upon the making of an
affidavit  of that fact by the holder  thereof,  such shares of Acquiror  Common
Stock (and cash in lieu of  fractional  shares) as may be  required  pursuant to
Section 1.6;  provided,  however,  that Acquiror may, in its discretion and as a
condition  precedent  to the issuance  thereof,  require the owner of such lost,
stolen  or  destroyed  Certificates  to  deliver  a bond in  such  sum as it may
reasonably  direct  as  indemnity  against  any claim  that may be made  against
Acquiror,  the Surviving  Corporation  or the Exchange Agent with respect to the
Certificates alleged to have been lost, stolen or destroyed.

     1.10 Tax and Accounting Consequences.  It is intended by the parties hereto
that the Merger  shall (i)  constitute  a  reorganization  within the meaning of
Section 368 of the Code and (ii) qualify for  accounting  treatment as a pooling
of  interests.  No party  shall take any action  which  would,  to such  party's
knowledge,  cause the Merger to fail to qualify as a  reorganization  within the
meaning of Section 368 of the Code or to qualify for  accounting  treatment as a
pooling of interests.  

     1.11 Exemption from Registration. The shares of Acquiror Common Stock to be
issued in connection with the Merger will be issued in a transaction exempt from
registration  under the  Securities  Act of 1933,  as amended  (the  "Securities
Act").  The  registration  of  the  shares  with  the  Securities  and  Exchange
Commission  (the  "SEC")  and their  resale  shall be  subject  to the terms and
conditions  of  a  Affiliates  Agreement  attached  hereto  as  Exhibit  C  (the
"Affiliates Agreement").

     1.2 Taking of Necessary Action;  Further Action.  If, at any time after the
Effective  Time,  any further  action is necessary or desirable to carry out the
purposes  of this  Agreement  and to vest the  Surviving  Corporation  with full
right, title and possession to all assets, property, rights, privileges,  powers
and  franchises  of Target,  the officers and directors of Target and Merger Sub
are fully authorized in the name of their  respective  corporations or otherwise
to take, and shall take, all such lawful and necessary  action,  so long as such
action is not inconsistent with this Agreement.

lettered  paragraphs  contained  in this Article II, and the  disclosure  in any
paragraph shall qualify only the corresponding paragraph in this Article II. Any

relief of debtors, and (ii) the availability of specific performance, injunctive
relief and other  equitable  remedies.  In the  remainder  of this  Article  II,

apply  separately  and  collectively  to)  Target  and any and each of  Target's
subsidiaries  (excluding  India Sub),  unless  otherwise  specifically set forth
below or unless the context otherwise requires.

     2.1  Organization,  Standing  and  Power.  Target  is  a  corporation  duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of its
jurisdiction  of  organization.  Target  has  the  corporate  power  to own  its
properties  and to carry on its business as now being  conducted and as proposed
to be conducted and is duly  qualified to do business and is in good standing in
each  jurisdiction  in which the failure to be so qualified and in good standing
would have a Material Adverse Effect on Target. Target has delivered to Acquiror
a true and correct copy of the Certificate of Incorporation  and Bylaws or other
charter documents, as applicable,  of Target, each as amended to date. Target is
not in violation of any of the provisions of its Certificate of Incorporation or
Bylaws  or  equivalent  organizational  documents.  Target  is the  owner of all
outstanding  shares of capital  stock of each of its  subsidiaries  and all such
shares are duly authorized, validly issued, fully paid and nonassessable. All of
the  outstanding  shares of capital stock of each such  subsidiary  are owned by
Target free and clear of any liens, charges, claims or encumbrances or rights of
others. There are no outstanding subscriptions,  options, warrants, puts, calls,
rights,   exchangeable  or  convertible   securities  or  other  commitments  or
agreements of any character  relating to the issued or unissued capital stock or
other securities of any such subsidiary,  or otherwise  obligating Target or any
such subsidiary to issue, transfer, sell, purchase,  redeem or otherwise acquire
any such securities. Except for Aspen India, , a subsidiary of Target located in
Dehli,  India  ("India  Sub"),  Target does not directly or  indirectly  own any
equity or similar  interest in, or any interest  convertible or  exchangeable or
exercisable   for,  any  equity  or  similar   interest  in,  any   corporation,
partnership, joint venture or other business association or entity.

     2.2 Capital  Structure.  The authorized capital stock of Target consists of
500,000 shares of Common Stock, of which there were issued and outstanding as of
the date of this Agreement,  150,000 shares of Common Stock.  There are no other
outstanding  shares of capital  stock or voting  securities  and no  outstanding
commitments to issue any shares of capital stock or voting  securities after the
date  of this  Agreement  other  than  pursuant  to the  exercise  of an  option
outstanding as of the date of this Agreement under the Target Stock Option Plan.
All  outstanding  shares of Target  Capital Stock are duly  authorized,  validly
issued,  fully paid and non-assessable and are free of any liens or encumbrances
other than any liens or  encumbrances  created by or  imposed  upon the  holders
thereof,  and are not subject to  preemptive  rights,  rights of first  refusal,
rights of first  offer or similar  rights  created by statute,  the  Articles of
Incorporation or Bylaws of Target or any agreement to which Target is a party or
by which it is bound. As of the date of this Agreement,  Target has reserved (i)
16,600 shares of Common Stock for issuance to Sunil  Khadilkar  upon exercise of
his option. Except for the rights created pursuant to this Agreement,  there are
no other  options,  warrants,  calls,  rights,  commitments or agreements of any
character to which Target is a party or by which it is bound  obligating  Target
to issue, deliver, sell, repurchase or redeem, or cause to be issued, delivered,
sold,  repurchased or redeemed, any shares of Target Capital Stock or obligating
Target to grant,  extend,  accelerate  the vesting  of,  change the price of, or
otherwise amend or enter into any such option,  warrant, call, right, commitment
or agreement. There are no contracts,  commitments or agreements relating to the
voting, purchase or sale of Target Capital Stock (i) between or among Target and
any of its shareholders and (ii) to the best of Target's knowledge, among any of
Target's  shareholders  or between  any of Target's  shareholders  and any third
party,  except for the shareholders  delivering  Irrevocable Proxies (as defined
below).  True and complete copies of all agreements and instruments  relating to
or issued under the option  granted to Sunil  Khadilkar have been made available
to Acquiror, and such agreements and instruments have not been amended, modified
or supplemented, and there are no agreements to amend, modify or supplement such
agreements  or  instruments  from the  form  made  available  to  Acquiror.  All
outstanding  Common Stock was issued in compliance  with all applicable  federal
and state securities laws. 

     2.3 Authority.

     (a) Target has all  requisite  corporate  power and authority to enter into
this  Agreement,  the Articles of Merger,  the  Stockholders  Agreement  and the
Escrow Agreement  (collectively,  the "Transaction Documents") and to consummate

their  respective  terms. 

     (c)  The  execution  and  delivery  of  this  Agreement,  the  Stockholders
Agreement  and the  other  Transaction  Documents  by  Target  do  not,  and the
consummation  of the  transactions  contemplated  hereby and  thereby  will not,
conflict  with, or result in any violation of, or default under (with or without
notice  or lapse of time,  or  both),  or give  rise to a right of  termination,
cancellation  or acceleration of any obligation or loss of any benefit under (i)
any provision of the Articles of Incorporation or Bylaws of Target,  as amended,

regulation applicable to Target or any of its properties or assets.

     (d) No  consent,  approval,  order or  authorization  of, or  registration,
declaration  or filing with, any court,  administrative  agency or commission or

registrations  which, if not obtained or made, would not have a Material Adverse
Effect on Target and would not prevent,  or materially alter or delay any of the
transactions  contemplated  by this  Agreement.  

     2.4 Offering  Memorandum.  The Offering Memorandum prepared by the Platinum
Group,  Inc.  previously  delivered to each  Acquiror has been  prepared in good
faith by the Target and does not contain any untrue statement of a material fact
nor does it omit to state a material fact necessary to make the statements  made
therein not misleading.

     2.5  Financial  Statements.  Target has delivered to Acquiror its unaudited
financial  statements (balance sheet and statement of operations) for the fiscal
years ended  December 31, 1997,  December 31, 1996 and December 31, 1995 and its
unaudited financial  statements (balance sheet and statement of operations) on a
consolidated  basis as at, and for the  six-month  period  ended  June 30,  1998
(collectively,  the "Financial Statements").  The Financial Statements have been
prepared in accordance with generally accepted  accounting  principles  ("GAAP")
(except  that the  unaudited  financial  statements  do not have notes  thereto)
applied on a consistent  basis  throughout  the periods  indicated and with each
other.  The Financial  Statements  fairly  present the  financial  condition and
operating  results of Target as of the  dates,  and for the  periods,  indicated
therein,  subject; in the case of the unaudited financing statements,  to normal
year-end  audit  adjustments  which are, not material in the  aggregate.  Target
maintains  a standard  system of  accounting  established  and  administered  in
accordance with generally accepted accounting principles.

     2.6 Absence of Certain  Changes.  Since June 30, 1998, (the "Target Balance
Sheet  Date"),  Target  has  conducted  its  business  in  the  ordinary  course
consistent with past practice and there has not occurred:  (i) any change, event
or  condition  (whether or not covered by  insurance)  that has  resulted in, or
might  reasonably be expected to result in, a Material Adverse Effect on Target;
(ii) any  acquisition,  sale or transfer of any material asset of Target;  (iii)
any  change  in  accounting  methods  or  practices  (including  any  change  in
depreciation or amortization  policies or rates) by Target or any revaluation by
Target of any of its assets; (iv) any declaration,  setting aside, or payment of
a dividend or other  distribution  with respect to the shares of Target,  or any
direct or indirect redemption, purchase or other acquisition by Target of any of
its shares of capital stock;  (v) any Material  Contract entered into by Target,
other than as provided to Acquiror, or any material amendment or termination of,
or default under,  any Material  Contract to which Target is a party or by which
it is bound;  (vi) any amendment or change to the Articles of  Incorporation  or
Bylaws  of  Target;  (vii)  any  material  increase  in or  modification  of the
compensation  or benefits  payable or to become  payable by Target to any of its
directors,  employees or consultants (viii) any agreement by Target to do any of
the things  described  in the  preceding  clauses (i) through  (vii) (other than
negotiations  with Acquiror and its  representatives  regarding the transactions
contemplated by this Agreement).


     2.7 Absence of Undisclosed Liabilities.  Target has no material obligations
or liabilities of any nature (matured or unmatured,  fixed or contingent)  other
than (i) those set forth or adequately provided for in the Balance Sheet for the
period ended June 30, 1998 (the "Target Balance Sheet"),  (ii) those incurred in
the ordinary  course of business  prior to the Target Balance Sheet Date and not
required  to be set forth in the Target  Balance  Sheet  under GAAP (iii)  those
incurred in the ordinary  course of business since the Target Balance Sheet Date
in amounts consistent with prior periods,  and (iv) those incurred in connection
with the execution of this Agreement.
                  

     2.8  Accounts  Receivable.  The  accounts  receivable  shown on the  Target
Balance Sheet arose in the ordinary  course of business and have been  collected
or are collectible in the book amounts thereof,  less the allowance for doubtful
accounts and returns provided for in such balance sheet. Allowances for doubtful
accounts and returns are adequate and have been prepared in accordance  with the
past  practices of Target.  The accounts  receivable of Target arising after the
date of the Target  Balance  Sheet and prior to the date hereof  arose,  and the
accounts  receivable  arising  prior to the  Effective  Time will arise,  in the
ordinary  course  of  business  and have been  collected  or, to the best of our
knowledge,  are  collectible in the book amounts  thereof,  less  allowances for
doubtful  accounts and returns  determined in accordance with the past practices
of Target.  None of the accounts receivable are subject to any material claim of
offset or  recoupment,  or  counterclaim  and  Target  has no  knowledge  of any
specific  facts that would be reasonably  likely to give rise to any such claim.
No material amount of accounts receivable are contingent upon the performance by
Target of any  obligation.  No agreement for deduction or discount has been made
with respect to any accounts receivable.

     2.9  Litigation.   There  is  no  private  or  governmental  action,  suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal,  foreign or domestic,  or, to the  knowledge of Target,  threatened
(including  allegations  that could form the basis for  future  action)  against
Target or any of its properties or officers or directors (in their capacities as
such), nor does Target have any reason to expect that any such activity,  threat
or allegation will be forthcoming. There is no judgment, decree or order against
Target,  or, to the  knowledge of Target,  any of its  directors or officers (in
their capacities as such),  that could prevent,  enjoin,  or materially alter or
delay any of the  transactions  contemplated  by this  Agreement,  or that could
reasonably  be  expected  to have a  Material  Adverse  Effect  on  Target.  All
litigation  to  which  Target  is a  party  (or,  to the  knowledge  of  Target,
threatened  to become a party) is disclosed in the Target  Disclosure  Schedule.
Target does not have any plans to initiate any litigation,  arbitration or other
proceeding against any third party.

     2.10 Restrictions on Business Activities. There is no agreement,  judgment,
injunction,  order or decree binding upon Target that has or could reasonably be
expected to have the effect of  prohibiting  or impairing  any current or future
business  practice  of Target,  any  acquisition  of  property  by Target or the
conduct of  business  by Target as  currently  conducted  or as  proposed  to be
conducted by Target.

     2.11 Governmental  Authorization.  Target has obtained each federal, state,
county, local or foreign governmental consent,  license, permit, grant, or other
authorization  of a Governmental  Entity (i) pursuant to which Target  currently
operates or holds any interest in any of its properties or (ii) that is required
for the operation of Target's  business or the holding of any such interest ((i)
and (ii) herein  collectively called "Target  Authorizations"),  and all of such
Target  Authorizations are in full force and effect, except where the failure to
obtain or have any such Target  Authorizations  could not reasonably be expected
to have a Material Adverse Effect on Target.

     2.12 Title to Property.  Target has good and marketable title to all of its
properties, interests in properties and assets, real and personal, necessary for
the conduct of its business as presently conducted or which are reflected in the
Target  Balance  Sheet or acquired  after the Target  Balance Sheet Date (except
properties,  interests in properties and assets sold or otherwise disposed of in
the ordinary  course of business since the Target  Balance Sheet Date),  or with
respect to leased properties and assets,  valid leasehold  interests therein, in
each  case  free  and  clear  of  all  mortgages,  liens,  pledges,  charges  or
encumbrances of any kind or character,  except (i) the lien of current taxes not
yet due and payable, (ii) such imperfections of title, liens and easements as do
not and  will  not  materially  detract  from or  interfere  with the use of the
properties subject thereto or affected thereby,  or otherwise  materially impair
business operations involving such properties and (iii) liens securing debt that
are reflected on the Target Balance Sheet. The plants, property and equipment of
Target that are used in the  operations  of its business  are in good  operating
condition  and  repair.  All  properties  used in the  operations  of Target are
reflected  in  the  Target  Balance  Sheet  to  the  extent  generally  accepted
accounting  principles  require  the same to be  reflected.  Target owns no real
property.

     2.13 Intellectual Property. For purposes of this Section only, Target shall
mean only Software  Moguls,  Inc. and not any of its  subsidiaries;  each of its
subsidiaries, to the extent necessary, shall be identified specifically.

     (iv)  Neither  Target  nor its India Sub have  received  any  communication
alleging or suggesting  that or  questioning  whether  Target has been or may be
(whether in its current or proposed  business or  otherwise)  engaged in, liable

name and address of each inventor),

     (i)      all patents and patent applications;

     (ii)      all registered and unregistered Marks; and

     (iii ) all registered and  unregistered  copyrights and mask works; and all

of any of the foregoing (except natural  expiration or termination at the end of
the full possible  term,  including  extensions  and renewals) is anticipated by
Target.  Except as  expressly  identified  in written  documentation  previously
provided to Acquiror (including without limitation file wrappers), Target is not
aware of any  questions or  challenges  (or any specific  basis  therefor)  with
respect to the validity of any of the  foregoing  issued or registered IP Rights
(or any part or claim thereof) or with respect to the patentability of any claim
of any of the foregoing patent applications.

     (c) There is, to the knowledge of Target, no unauthorized Use,  disclosure,

standard  Consulting  Agreement (in the case of a contractor)  (which  agreement
provides  valid  written  assignments  of all  title and  rights  to any  Target
Intellectual  Property  conceived  or  developed  thereunder,  or  otherwise  in
connection  with his or her consulting or  employment,  but not already owned by
Target by  operation  of law)  (copies of such  agreements  are  included in the
Schedules hereto).

     (f) To Target's knowledge, Target is not Using and it will not be necessary
to  Use,  (i)  any  Inventions  of any of  its  past  or  present  employees  or
contractors (or people currently  intended to be hired) made prior to or outside
the scope of their employment by Target or (ii) any confidential  information or
trade secrets of any former employer of any such person.

     2.14  Environmental  Matters.  Target is and has at all times  operated its
business in material  compliance with all Environmental  Laws and to the best of
Target's knowledge, no material expenditures are or will be required in order to
comply with such Environmental Laws.  "Environmental  Laws" means all applicable
statutes, rules, regulations,  ordinances,  orders, decrees, judgments, permits,
licenses, consents, approvals,  authorizations, and governmental requirements or
directives or other obligations lawfully imposed by governmental authority under
federal,  state or local law  pertaining to the  protection of the  environment,
protection  of public  health,  protection  of worker  health  and  safety,  the
treatment,  emission and/or  discharge of gaseous,  particulate  and/or effluent
pollutants,  and/or the  handling  of  hazardous  materials,  including  without
limitation,   the  Clean  Air  Act,  42  U.S.C.   Section  7401,  et  seq.,  the
Comprehensive  Environmental  Response,  Compensation  and Liability Act of 1980
("CERCLA"), 42 U.S.C. Section 9601, et seq., the Federal Water Pollution Control

     2.15      Taxes.

     (a) All Tax returns, statements,  reports, declarations and other forms and
documents  (including without  limitation  estimated Tax returns and reports and
material  information  returns  and  reports)  required to be filed with any Tax
authority with respect to any Taxable period ending on or before the Closing, by
or on behalf of Target  (collectively,  "Tax  Returns" and  individually  a "Tax
Return"),  have been or will be  completed  and filed  when due  (including  any
extensions  of such due date)  except where the failure to file would not have a
Material  Adverse Effect on Target and all amounts shown due on such Tax Returns
on or before the Effective Time (and all other material Taxes due and payable on
or before the Effective  Time) have been or will be paid on or before such date.
The Target  Financial  Statements  (i) fully  accrue  all actual and  contingent
liabilities  for Taxes with  respect to all periods  through the Target  Balance
Sheet Date and Target has not and will not incur any Tax  liability in excess of
the  amount  reflected  on the  Target  Balance  Sheet  included  in the  Target
Financial Statements with respect to such periods,  other than Taxes incurred in
the ordinary course of its business following the Target Balance Sheet, and (ii)
properly  accrues in  accordance  with GAAP all material  liabilities  for Taxes
payable  after  June 30,  1998  with  respect  to all  transactions  and  events
occurring on or prior to such date.  All  information  set forth in the notes to
the Target Financial  Statements  relating to Tax matters is true,  complete and
accurate in all material respects. No material Tax liability since June 30, 1998
has been incurred by Target other than in the ordinary  course of business,  and
adequate  provision  has been made by Target  for all Taxes  since  that date in
accordance with GAAP on at least a quarterly basis.

     (b) Target has previously  provided or made available to Acquiror true and
correct copies of all income,  franchise,  and sales Tax Returns for the periods
beginning  on or after  January 1, 1991.  Target  has  withheld  and paid to the
applicable  financial  institution  or Tax authority all amounts  required to be
withheld.  No Tax Returns filed with respect to Taxable years of Target  through
the Taxable year ended  December 31, 1994. in the case of the United States have
been  examined and such Taxable  years are now closed.  Target (or any member of
any  affiliated  or  combined  group of which  Target has been a member) has not
granted any extension or waiver of the limitation  period  applicable to any Tax
Returns  that is still in effect.  There is no material  claim,  audit,  action,
suit,  proceeding,  or (to the knowledge of Target) investigation now pending or
(to the  knowledge  of Target)  threatened  against or with respect to Target in
respect of any Tax or assessment. No notice of deficiency or similar document of
any Tax authority has been received by Target,  and there are no liabilities for
Taxes  (including  liabilities  for  interest,  additions  to Tax and  penalties
thereon and related  expenses)  with respect to the issues that have been raised
(and are  currently  pending) by any Tax  authority  that could,  if  determined
adversely to Target, materially and adversely affect the liability of Target for
Taxes.  There are no liens for Taxes  (other than for current  Taxes not yet due
and  payable)  upon the assets of  Target.  Target has never been a member of an
affiliated  group of  corporations,  within the  meaning of Section  1504 of the
Code.  Target is in full compliance with all the terms and conditions of any Tax
exemptions or other Tax-sharing  agreement or order of a foreign  government and
the consummation of the Merger will not have any adverse effect on the continued
validity  and  effectiveness  of any such  Tax  exemption  or other  Tax-sharing
agreement  or order.  Neither  Target  nor any  person  on behalf of Target  has
entered  into or will  enter  into any  agreement  or  consent  pursuant  to the
collapsible  corporation  provisions  of  Section  341(f)  of the  Code  (or any
corresponding  provision of state, local or foreign income tax law) or agreed to
have  Section  341(f)(2) of the Code (or any  corresponding  provision of state,
local or foreign income tax law) apply to any  disposition of any asset owned by
Target.  None of the assets of Target is  property  that  Target is  required to
treat as being owned by any other person  pursuant to the so-called "safe harbor
lease" provisions of former Section 168(f)(8) of the Code. None of the assets of
Target  directly  or  indirectly  secures  any  debt  the  interest  on which is
tax-exempt  under  Section  103(a) of the Code.  None of the assets of Target is
"tax-exempt  use  property"  within the  meaning of Section  168(h) of the Code.
Target has not made and will not make a deemed  dividend  election  under Treas.
Reg.  Section1.1502-32(f)(2) or a consent dividend election under Section 565 of
the Code.  Target has never been a party to any transaction  intended to qualify
under Section 355 of the Internal Revenue Code or any corresponding provision of
state  law.  Target has not  participated  in (and will not  participate  in) an
international  boycott  within the meaning of Section 999 of the Code. No Target
shareholder is other than a United States person within the meaning of the Code.
Target  does not have and has not had a permanent  establishment  in any foreign
country,  as defined in any  applicable  tax treaty or  convention  between  the
United States of America and such foreign  country and Target has not engaged in
a trade or business within any foreign  country.  Target has elected pursuant to
Section 1362 of the Code to be treated as an "S" corporation  (the "Subchapter S
Election"),  commencing  January 1, 1987, and the Target and the shareholders of
the Target have  reported  income and filed tax returns  consistently  therewith
since that date. The Target's Subchapter S Election shall remain in effect until
terminated  by the  Merger.  The  Target has not had and does not expect to have
liability or any potential or deferred  liability for Taxes  pursuant to Section
1371(d)(2),  Section 1374 or Section  1375 of the Code,  nor has the Target been
subjected to any other taxes (other than state income taxes) imposed pursuant to
or resulting from its Subchapter S Election.  Apart from  thereafter  subjecting
the Target to income taxation, termination of the Subchapter S Election will not
have a Material Adverse Effect on the Target,  its financial  condition,  or its
business  as  presently  conducted  or proposed  to be  conducted  or any of its
properties or material assets.  All material  elections with respect to Target's
Taxes made during the fiscal years ending,  December 31, 1995, 1996 and 1997 are
reflected on the Target Tax Returns for such periods,  copies of which have been
provided or made  available to Acquiror.  After the date of this  Agreement,  no
material  election  with respect to Taxes will be made without the prior written
consent of Acquiror, which consent will not be unreasonably withheld or delayed.
Target is not party to any joint venture,  partnership,  or other arrangement or
contract  which  could be  treated  as a  partnership  for  federal  income  tax
purposes.  Target is not  currently  and never has been subject to the reporting
requirements  of Section 6038A of the Code.  There is no agreement,  contract or
arrangement to which Target is a party that could, individually or collectively,
result in the  payment of any amount that would not be  deductible  by reason of
Sections 280G (as determined  without regard to Section  280G(b)(4),  162 (other
than  162(a)  and (b)) or 404 of the Code.  Target is not a party to or bound by
any Tax indemnity,  Tax sharing or Tax allocation  agreement (whether written or
unwritten  or arising  under  operation  of  federal  law as a result of being a
member of a group filing  consolidated  Tax returns,  under operation of certain
state laws as a result of being a member of a unitary group, or under comparable
laws of other states or foreign jurisdictions) which includes a party other than
Target nor does Target owe any amount under any such  Agreement.  Target is not,
and has not been, a United States real property holding  corporation (as defined
in Section  897(c)(2) of the Code)  during the  applicable  period  specified in
Section 897(c)(1)(A)(ii) of the Code. Other than by reason of the Merger, Target
has not been and will not be  required  to include any  material  adjustment  in
Taxable income for any Tax period (or portion  thereof)  pursuant to Section 481
or 263A of the Code or any comparable  provision under state or foreign Tax laws
as a result of transactions,  events or accounting methods employed prior to the
Merger.

     (c) For purposes of this Agreement,  the following terms have the following
meanings: "Tax" (and, with correlative meaning, "Taxes" and "Taxable") means any
and all taxes including,  without limitation, (i) any net income, alternative or
add-on  minimum tax,  gross  income,  gross  receipts,  sales,  use, ad valorem,
transfer,  franchise,  profits,  value added, net worth,  license,  withholding,

Governmental  Entity (a "Tax  authority")  responsible for the imposition of any
such tax  (domestic  or  foreign),  (ii) any  liability  for the  payment of any
amounts  of the  type  described  in (i) as a result  of  being a  member  of an

the result of being a transferee  or successor  thereof and (iii) any  liability
for the payment of any amounts of the type  described in (i) or (ii) as a result
of any express or implied  obligation to indemnify any other person.  As used in
this Section 2.15, the term "Target" means Target and any entity included in, or
required under GAAP to be included in, any of the Target Financial Statements.

direct or  indirect  ownership  interest in any firm or  corporation  with which
Target is  affiliated or with which Target has a business  relationship,  or any
firm or  corporation  that  competes  with  Target,  except to the  extent  that
employees,  officers,  or  directors  of Target and  members of their  immediate
families  own stock in  publicly  traded  companies  that may  compete  with the

advertising, or any other material violation of any laws or regulations relating
to  anti-competitive  practices or unfair trade  practices of any kind,  and, to

any valid basis for any such claim.

"Confidentiality Agreement"),  which Confidentiality Agreement shall continue in
full force and effect in accordance with its terms.

     5.5  Public  Disclosure.  Unless  otherwise  permitted  by this  Agreement,
Acquiror  and Target  shall  consult  with each other  before  issuing any press
release or otherwise  making any public statement or making any other public (or

regarding the terms of this Agreement and the transactions  contemplated hereby,
and neither  shall issue any such press  release or make any such  statement  or
disclosure  without the prior approval of the other (which approval shall not be

consent of the other, except as may be required by law.

     5.6 Consents; Cooperation.

     (a) Each of Acquiror and Target shall promptly apply for or otherwise seek,
and use its best efforts to obtain,  all consents and  approvals  required to be
obtained by it for the consummation of the Merger and shall use its best efforts
to  obtain  all  necessary  consents,  waivers  and  approvals  under any of its
material  contracts in connection with the Merger for the assignment  thereof or
otherwise.  The parties hereto will consult and cooperate with one another,  and
consider  in good  faith  the  views  of one  another,  in  connection  with any
analyses, appearances, presentations, memoranda, briefs, arguments, opinions and
proposals  made or submitted  by or on behalf of any party hereto in  connection
with  proceedings  under or relating to any federal or state  antitrust  or fair
trade law.

     (b)  Notwithstanding  the foregoing,  neither  Acquiror nor Target shall be
required to agree,  as a condition to any Approval,  to divest itself of or hold
separate  any  subsidiary,  division or  business  unit which is material to the
business  of  such  party  and  its  subsidiaries,  taken  as a  whole,  or  the
divestiture  or holding  separate of which would be reasonably  likely to have a
Material Adverse Effect on (A) the business,  properties,  assets,  liabilities,
financial condition or results of operations of such party and its subsidiaries,
taken as a whole or (B) the  benefits  intended to be derived as a result of the
Merger.

     5.7 Pooling Accounting. Acquiror and Target shall each use its best efforts
to cause the business  combination  to be effected by the Merger to be accounted

necessary  to permit such  treatment.  Each of Acquiror and Target shall use its
best  efforts (i) to cause its  respective  "Affiliates"  (as defined in Section

to  account  for the  business  combination  to be  effected  by the Merger as a
pooling of interests and (ii) to cause Acquiror's auditors to deliver the letter

any event which would be likely to cause any condition to the obligations of any
party to effect  the  Merger  and the other  transactions  contemplated  by this
Agreement not to be  satisfied,  or (ii) the failure of Target to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it pursuant to this  Agreement  which would be likely to result in any condition
to the obligations of any party to effect the Merger and the other  transactions
contemplated  by this Agreement not to be satisfied.  The delivery of any notice
pursuant to this Section 5.8 shall not cure any breach of any  representation or
warranty requiring disclosure of such matter prior to the date of this Agreement
or  otherwise  limit or affect the  remedies  available  hereunder  to the party
receiving such notice,  provided that such party,  within ten days after receipt
of such notice, advises the other party of its objection to the matter disclosed
in such notice and the nature of such objection.

     5.9 Affiliates Agreements. Prior to the execution of this Agreement, Target
will  provide  to the  Acquiror a list of those  persons  who are,  in  Target's
reasonable  judgment,  "affiliates"  of Target,  within the  meaning of Rule 145
under the Securities Act ("Rule 145"). Each such person who is an "affiliate" of
the  Target  within  the  meaning  of  Rule  145 is  referred  to  herein  as an
"Affiliate." Target shall provide to the Acquiror such information and documents
as Acquiror  shall  reasonably  request for purposes of reviewing  such list and

their  respective  subsidiaries  to, take all  reasonable  actions  necessary to
comply  promptly with all legal  requirements  which may be imposed on them with
respect to the consummation of the  transactions  contemplated by this Agreement

necessary in connection with any such requirements imposed upon such other party
in connection  with the  consummation of the  transactions  contemplated by this
Agreement  and will take all  reasonable  actions  necessary to obtain (and will

Governmental  Entity  or  other  person,  required  to be  obtained  or  made in
connection with the taking of any action contemplated by this Agreement.

     5.12 Tax-Free Reorganization. Neither Target, Acquiror nor Sub will, either
before or after  consummation  of the  Merger,  take any  action  which,  to the
knowledge  of such  party,  would  cause  the  Merger  to fail to  constitute  a
"reorganization" within the meaning of Code Section 368.

     5.13 Stock  Options.  At the Effective  Time,  each  outstanding  option to
purchase shares of Target Common Stock,  whether vested or unvested,  shall have

the date hereof of all holders of  outstanding  options  under the Target  Stock
Option Plan  including  the number of shares of Target  Capital Stock subject to
each such option, the exercise or vesting schedule, the exercise price per share
and the term of each such option.  On the Closing Date,  Target shall deliver to
Acquiror an updated Option Schedule current as of such date.

this  Agreement,  subject  to the  appropriate  vote of  shareholders  of Target
described  in Section  5.2,  including  cooperating  fully with the other party,
including by provision of  information.  In case at any time after the Effective

this  Agreement  or to vest the  Surviving  Corporation  with full  title to all
properties,  assets, rights,  approvals,  immunities and franchises of either of
the constituent corporations, the proper officers and directors of each party to
this Agreement shall take all such necessary action.

     5.16 Employee Benefits. Acquiror shall take such reasonable actions, to the
extent  permitted by  Acquiror's  benefits  program,  as are  necessary to allow
eligible employees of Target to participate in the benefit programs of Acquiror,
or alternative  benefits programs in the aggregate  substantially  comparable to
those  applicable  to  employees  of  Acquiror  on  similar  terms,  as  soon as
practicable after the Effective Time of the Merger but, in any event, not before
January 1, 1999.  For purposes of  satisfying  the terms and  conditions of such
programs, to the extent permitted by Acquiror's benefit programs, Acquiror shall
use reasonable  efforts to give full credit for  eligibility or vesting for each
participant's  period of service with Target. Prior to January 1, 1999, Acquiror
agrees to continue Target's existing benefit programs substantially as currently
provided,  except that no commitment is made with respect to the 401(k) Plan and
Dental Plan.

Shareholders'  Representative  (as  defined in Section  8.9) an  opportunity  to
review and comment upon such  returns  prior to filing.  Acquiror  agrees not to

                                  ARTICLE VIII

                           ESCROW AND INDEMNIFICATION

     8.1 Survival of Representations,  Warranties and Covenants. Notwithstanding
any   investigation   conducted   before  or  after  the   Closing   Date,   and
notwithstanding  any  actual  or  implied  knowledge  or  notice of any facts or
circumstances   which   Acquiror  or  Target  may  have  as  a  result  of  such
investigation  or  otherwise,  Acquiror and Target will be entitled to rely upon
the other party's  representations,  warranties  and covenants set forth in this
Agreement.  The  representations  and warranties of Acquiror will terminate upon
the Closing.  The  obligations  of Target with  respect to its  representations,
warranties,  agreements  and covenants  will survive the Closing and continue in
full force and effect  until the date twelve (12) months  following  the Closing
Date (the  "Termination  Date"),  at which  time,  subject to Section  8.5,  the
representations, warranties and covenants Target set forth in this Agreement and
any liability of the holders of Target Capital Stock (collectively,  the "Former
Target  Shareholders")  with respect to those  representations,  warranties  and
covenants will terminate.

     8.2 Indemnity. From and after the Effective Time of the Merger, and subject
to the provisions of Section 8.1, Acquiror and the Surviving  Corporation (on or
after the Closing  Date) shall be  indemnified  and held  harmless by the Former
Target Shareholders  against, and reimbursed for, any actual liability,  damage,
loss, obligation,  demand,  judgment, fine, penalty, cost or expense, other than
any such damages  resulting from injunctive relief granted as to an intellectual
property  claim),  but including  reasonable  attorneys' fees  (excluding  costs
relating to in-house  attorneys)  and expenses,  and the costs of  investigation
incurred in defending against or settling such liability,  damage, loss, cost or
expense or claim therefor and any amounts paid in settlement thereof) imposed on
or reasonably  incurred by Acquiror or the Surviving  Corporation as a result of
any breach of any representation, warranty, agreement or covenant on the part of
Target under this Agreement  (collectively the "Damages").  Damages in each case
shall be net of the amount of any insurance proceeds, indemnity and contribution
actually recovered by Acquiror or the Surviving  Corporation.  "Damages" as used
herein is not limited to matters asserted by third parties, but includes Damages
incurred or sustained by Acquiror in the absence of claims by a third party.

     8.3 Escrow Fund. As security for the indemnity  provided for in Section 8.2
hereof,  ten percent  (10%) of the Shares  issuable  pursuant to Section  1.6(a)
shall be deposited by Acquiror in an escrow account with Louis C. Cole (or other
mutually acceptable person or institution) as Escrow Agent (the "Escrow Agent"),
as of the Closing  Date,  such deposit to constitute an escrow fund (the "Escrow
Fund")  to be  governed  by the  terms  set  forth  in  this  Agreement  and the
provisions  of an Escrow  Agreement  to be executed  and  delivered  pursuant to
Section  5.16.  The Escrow  Fund  shall be  allocated  among the  Former  Target
Shareholders  on a  pro-rata  basis in  accordance  with the number of shares of
Target  Capital  Stock held by the Former Target  Shareholders  at the Effective
Time (excluding for purposes of this  calculation any Dissenting  Shares).  Upon
compliance  with the terms hereof and subject to the  provisions of this Article
VIII,  Acquiror  and the  Surviving  Corporation  shall be  entitled  to  obtain
indemnity from the Escrow Fund for Damages covered by the indemnity provided for
in Section 8.2 of this Agreement.

     8.4  Limitations.   Notwithstanding  anything  in  this  Agreement  to  the
contrary,  all claims for indemnification by Acquiror and Surviving  Corporation
which may be made under or in connection with this Agreement and the Transaction
Documents are subject to the following conditions, limitations and restrictions:

     (a)  Acquiror  may not  receive  any shares from the Escrow Fund unless and
until an  Officer's  Certificate  (as defined in Section 8.6 below)  identifying
Damages the aggregate  amount of which exceeds $50,000 has been delivered to the
Escrow Agent as provided  below and such amount is  determined  pursuant to this
Article VIII to be payable and then only for such  individual  damages or series
of related  damages  that exceed the amount of $15,000,  in which case  Acquiror
shall receive shares equal in value to the full amount of Damages.

     (b) The sole remedy for the Acquiror and Surviving  Corporation  for claims
under this Agreement and the  Transaction  Documents is limited to return of the
shares held in the Escrow  Fund.  

     8.5 Escrow Period.  The Escrow Period shall  terminate at the expiration of
twelve (12) months after the Effective  Time.  Half of the escrowed shares shall
be  released  from  escrow six (6) months  following  the  Closing  date and the
balance of the escrowed  shares shall be released from escrow twelve (12) months
following the Closing Date (or such shorter  period as may be required under the
pooling rules and regulations);  provided, however, that a portion of the Escrow
Shares,  which are necessary to satisfy any unsatisfied  claims specified in any
Officer's  Certificate  theretofore  delivered  to the  Escrow  Agent  prior  to
termination  of the  Escrow  Period  with  respect  to facts  and  circumstances
existing  prior to expiration of the Escrow  Period,  shall remain in the Escrow
Fund until such claims have been finally resolved.

     8.6 Claims upon Escrow Fund.

     (a) Upon receipt by the Escrow Agent on or before the Termination Date of a
certificate signed by the chief financial or chief executive officer of Acquiror
(an "Officer's Certificate"):

     (i) stating that Acquiror or the Surviving  Corporation has incurred,  paid
or properly accrued (in accordance with GAAP) or knows of facts giving rise to a
reasonable  probability  which  will  require  it to incur,  pay or  accrue  (in
accordance  with GAAP)  Damages in an  aggregate  stated  amount with respect to
which  Acquiror or the  Surviving  Corporation  is entitled to payment  from the
Escrow Fund pursuant to this Agreement; and

     (ii)  specifying  in  reasonable  detail  the  individual  items of Damages
included in the amount so stated, the date each such item was incurred,  paid or
properly  accrued (in accordance with GAAP),  or the basis for such  anticipated
liability,  the specific nature of the breach to which such item is related, the
Escrow Agent shall,  subject to the provisions of Section 8.7 of this Agreement,
deliver to Acquiror  shares of Acquiror  Common Stock in an amount  necessary to
indemnify Acquiror for the Damages claimed.  All shares of Acquiror Common Stock
subject to such  claims  shall  remain in the  Escrow  Fund  until  Damages  are
actually  incurred or paid or the Acquiror  determines  in its  reasonably  good
faith judgment that no Damages will be required to be incurred or paid (in which
event such shares shall be  distributed  to the Former  Target  Shareholders  in
accordance  with  Section  8.10  below).  

     (b) For the purpose of  compensating  Acquiror for its Damages  pursuant to
this Agreement,  the Acquiror Common Stock in the Escrow Fund shall be valued at
the Closing Price.

     8.7  Objections  to  Claims.  At the  time  of  delivery  of any  Officer's
Certificate to the Escrow Agent, a duplicate copy of such Officer's  Certificate
shall be delivered to the Shareholders'  Representative  (defined in Section 8.9
below)  and for a period of  forty-five  (45) days after  such  delivery  to the
Escrow Agent,  the Escrow Agent shall make no delivery of Acquiror  Common Stock
or other  property  pursuant to Section 8.6 hereof unless the Escrow Agent shall
have received written  authorization  from the  Shareholders'  Representative to
make such delivery;  provided,  however, that if such Officer's Certificate sets
forth a claim for the  recovery by Acquiror of expenses  incurred in  connection
with the Merger in excess of $250,000 for which the Target's  Shareholders  have
not promptly  reimbursed Acquiror pursuant to the terms of Section 7.3 above (an
"Expense  Recovery"),  then the Escrow Agent may make such delivery  without the
requirement of a written authorization from the Shareholders'  Representative at
any time that is ten (10) days after the delivery of such Officer's  Certificate
to the Escrow  Agent.  After the  expiration  of such ten (10) day or forty-five
(45) day period,  as  applicable,  the Escrow  Agent shall make  delivery of the
Acquiror  Common Stock or other  property in the Escrow Fund in accordance  with
Section 8.6 hereof,  provided  that,  except in the case of an Expense  Recovery
(where no objection may be made), no such payment or delivery may be made if the
Shareholders'  Representative  shall object in a written  statement to the claim
made in the Officer's Certificate,  and such statement shall have been delivered
to the Escrow Agent and to Acquiror prior to the  expiration of such  forty-five
(45) day period.

     8.8 Resolution of Conflicts; Arbitration.

     (a) In case the Shareholders'  Representative shall so object in writing to
any  claim  or  claims  by  Acquiror  made  in any  Officer's  Certificate,  the
Shareholders'  Representative and Acquiror shall attempt in good faith for sixty
(60) days to agree upon the rights of the  respective  parties  with  respect to
each of such claims. If the Shareholders'  Representative and Acquiror should so
agree, a memorandum setting forth such agreement shall be prepared and signed by
both parties and shall be furnished to the Escrow Agent.  The Escrow Agent shall
be entitled to rely on any such  memorandum  and shall  distribute  the Acquiror
Common Stock or other property from the Escrow Fund in accordance with the terms
thereof.

     (b) If no such  agreement  can be reached  after  good  faith  negotiation,
either Acquiror or the Shareholders'  Representative  may demand  arbitration of
the  matter  unless  the  amount of the  damage  or loss is at issue in  pending
litigation with a third party, in which event arbitration shall not be commenced
until such amount is  ascertained or both Acquiror and the  Shareholder's  Agent
agree  to  arbitration;  and in such  event  the  matter  shall  be  settled  by
arbitration  conducted by a single  arbitrator.  Acquiror and the  Shareholder's
Agent shall jointly select an arbitrator. If Acquiror or the Shareholder's Agent
fail to agree upon an arbitrator within thirty (30) days, an arbitrator shall be
selected for them by the American Arbitration  Association ("AAA"). The decision
of the arbitrator so selected as to the validity and amount of any claim in such
Officer's  Certificate  shall be binding and conclusive  upon the parties to the
Agreement,  and, notwithstanding anything in Section 8.6, the Escrow Agent shall
be  entitled  to act in  accordance  with  such  decision  and make or  withhold
payments  or  distributions  out of the  Escrow  Fund in  accordance  with  such
decision.

     (c) Judgment upon any award rendered by the  arbitrators  may be entered in
any court having jurisdiction. Any such arbitration shall be held in Santa Clara
County,  California  under the  commercial  rules then in effect of the American
Arbitration  Association (the "AAA"). Such arbitration shall be conducted by one
(1)  arbitrator  chosen by mutual  agreement of Acquiror  and the  Shareholders'
Representative,  or failing such agreement,  an arbitrator appointed by the AAA.
There shall be limited  discovery prior to the  arbitration  hearing as follows:
(a) exchange of witness lists and copies of  documentary  evidence and documents
related to or arising out of the issues to be arbitrated, (b) depositions of all
party  witnesses,  and (c)  such  other  depositions  as may be  allowed  by the
arbitrator  upon a showing of good  cause.  Depositions  shall be  conducted  in
accordance with the California Code of Civil Procedure,  the arbitrator shall be
required  to provide in writing to the  parties the basis for the award or order
of such  arbitrator,  and a court reporter shall record all hearings,  with such
record  constituting the official  transcript of such proceedings.  Any order or
award of the arbitrator in accordance with the foregoing shall be final, binding
and  conclusive  as to the parties to this  Article  VIII.  For purposes of this
Section  8.8,  in any  arbitration  hereunder  in which any claim or the  amount
thereof  stated in the  Officer's  Certificate  is at issue,  Acquiror  shall be
deemed to be the Non-Prevailing Party unless the arbitrators award Acquiror more
than one-half  (1/2) of the amount in dispute,  plus any amounts not in dispute;
otherwise,  the  Target  shareholders  for whom  shares of Target  Common  Stock
otherwise  issuable  to them have been  deposited  in the  Escrow  Fund shall be
deemed  to  be  the  Non-Prevailing   Party.  The  Non-Prevailing  Party  to  an
arbitration  shall  pay its own  expenses,  the  fees  of each  arbitrator,  the
administrative fee of the American  Arbitration  Association,  and the expenses,
including without limitation,  attorneys' fees and costs, reasonably incurred by
the other party to the arbitration.

     8.9 Shareholders' Representative.

     (a)  Sunil   Khadilkar   shall  be  constituted   and  appointed  as  agent
("Shareholders' Representative") for and on behalf of the Target shareholders to
give and receive notices and  communications,  to authorize delivery to Acquiror
of the  Acquiror  Common  Stock  or  other  property  from  the  Escrow  Fund in
satisfaction of claims by Acquiror,  to object to such deliveries,  to agree to,
negotiate, enter into settlements and compromises of, and demand arbitration and
comply  with  orders of courts and awards of  arbitrators  with  respect to such
claims,  and to take all actions necessary or appropriate in the judgment of the
Shareholders'  Representative  for the  accomplishment  of the  foregoing.  Such
agency may be changed by the  holders of a majority  in  interest  of the Escrow
Fund  from  time to time upon not less  than 10 days'  prior  written  notice to
Acquiror. The Shareholder's Agent may resign upon thirty (30) days notice to the
parties to this Agreement and the Former Target  Shareholders.  No bond shall be
required   of  the   Shareholders'   Representative,   and   the   Shareholders'
Representative  shall  receive  no  compensation  for his  services.  Notices or
communications  to or from the  Shareholders'  Representative  shall  constitute
notice to or from each of the Target shareholders.

     (b) The Shareholders'  Representative  shall not be liable for any act done
or omitted hereunder as Shareholders'  Representative while acting in good faith
and in the exercise of reasonable judgment, and any act done or omitted pursuant
to the advice of counsel  shall be conclusive  evidence of such good faith.  The
Target shareholders shall severally  indemnify the Shareholders'  Representative
and hold him harmless  against any loss,  liability or expense  incurred without
gross  negligence or bad faith on the part of the  Shareholders'  Representative
and arising out of or in connection with the acceptance or administration of his
duties hereunder.

     (c) The  Shareholders'  Representative  shall  have  reasonable  access  to
information about Target and the reasonable  assistance of Target's officers and
employees  for  purposes  of  performing  its duties and  exercising  its rights
hereunder,   provided  that  the   Shareholders'   Representative   shall  treat
confidentially  and not disclose any nonpublic  information from or about Target
to anyone (except on a need to know basis to individuals who agree to treat such
information confidentially).

     (d) The  Shareholders'  Representative  shall be entitled to a distribution
from the  Escrow  Fund  equal to any such  indemnity  claim  which  has not been
satisfied;  provided, however, that no such distribution shall be made until all
claims of  Acquiror  set forth in any  Officer's  Certificate  delivered  to the
Escrow Agent on or prior to the Termination Date have been resolved.

     8.10  Distribution  Upon  Termination  of Escrow  Period.  Within  five (5)
business days following the Termination  Date, the Escrow Agent shall deliver to
the Former Target Shareholders all of the Shares in the Escrow Fund in excess of
any amount of such Shares  reasonably  necessary to satisfy any  unsatisfied  or
disputed claims for Damages specified in any Officer's  Certificate delivered to
the  Escrow  Agent on or before  the  Termination  Date and any  unsatisfied  or
disputed  claims by the  Shareholder's  Agent under  Section 8.9. As soon as all
such claims have been  resolved,  the Escrow  Agent shall  deliver to the Former
Target  Shareholders all Shares remaining in the Escrow Fund and not required to
satisfy  such claims.  Deliveries  of Shares to the Former  Target  Shareholders
pursuant to this section shall be made in proportion to the allocation set forth
in Section 8.3.

     8.11 Actions of the Shareholders' Representative.  A decision, act, consent
or instruction of the Shareholders'  Representative  shall constitute a decision
of all Target  shareholders  for whom shares of Acquiror  Common Stock otherwise
issuable to them are  deposited  in the Escrow Fund and shall be final,  binding
and  conclusive  upon each such  Target  shareholder,  and the Escrow  Agent and
Acquiror  may  rely  upon any  decision,  act,  consent  or  instruction  of the
Shareholders'  Representative as being the decision, act, consent or instruction
of each and every such Target  shareholder.  The Escrow  Agent and  Acquiror are
hereby  relieved  from any  liability to any person for any acts done by them in
accordance with such decision,  act, consent or instruction of the Shareholders'
Representative.

     8.12  Third-Party  Claims.  In  the  event  Acquiror  becomes  aware  of  a
third-party  claim which  Acquiror  believes may result in a demand  against the
Escrow Fund,  Acquiror  shall notify the  Shareholders'  Representative  of such
claim, and the Shareholders'  Representative shall be entitled,  at his expense,
to  participate  in any defense of such claim.  Acquiror shall have the right in
its sole discretion to settle any such claim;  provided,  however, that Acquiror
may not  effect the  settlement  of any such claim  without  the  consent of the
Shareholders' Representative,  which consent shall not be unreasonably withheld.
In the event that the  Shareholders'  Representative  has  consented to any such
settlement, the Shareholders' Representative shall have no power or authority to
object  under  Section 8.6 or any other  provision  of this  Article VIII to the
amount of any claim by  Acquiror  against  the Escrow  Fund for  indemnity  with
respect to such settlement.

     8.13 Indemnity of Escrow Agent.  Acquiror,  Target and Signing Stockholders
hereby  individually  and severally agree to indemnify  Escrow Agent and hold it
harmless  against any claim which may be made against it in connection  with its
actions  as Escrow  Agent  hereunder,  including  any loss to the  extent of the
aggregate  amount paid in settlement of any litigation  commenced or threatened,
or for any claim  whatsoever as set forth herein,  including any expense or loss
incurred by it in  connection  with such claim,  if such  settlement is effected
with  the   written   consent  of   Acquiror,   Target  and  the   Shareholders'
Representative;  provided that Escrow Agent shall not be indemnified against any
such loss, damage, expense,  liability or claim arising out of or based upon its
failure to perform in accordance  with this  Agreement or arising out of its bad
faith,  negligence,  or willful  failure to perform its  obligations;  provided,
further, that the Signing Stockholders,' Target's and Acquiror's indemnification
obligations shall be limited to the Common Stock or other property in the Escrow
Fund at the time the Escrow Agent makes a claim for indemnity  hereunder.  In no
case shall the Acquiror, Target or the Signing Stockholders be liable under this
Escrow  Agreement  with respect to any lawsuit filed against Escrow Agent unless
the Acquiror,  Target and the Signing Stockholders are notified by Escrow Agent,
by letter,  telegram or telex  confirmed by letter,  of the  commencement of any
such action  within a  reasonable  time after such person shall have been served
with a summons or other first legal process giving  information as to the nature
and basis of the lawsuit, but failure to so notify the Acquiror,  Target and the
Signing  Stockholders  shall not  relieve the  Acquiror,  Target and the Signing
Stockholders  from any liability they may have otherwise than on account of this
Article  VIII.  Acquiror,  Target  and the  Signing  Stockholders  shall each be
entitled to participate at their own expense in the defense of any such lawsuit,
and if one of the parties so elects  within a reasonable  time after  receipt of
such notice,  upon  receiving  consent  from the other  party,  such party shall
assume the defense of any lawsuit. In the event that a party assumes the defense
of any lawsuit,  such defense shall be conducted by counsel chosen by such party
and  satisfactory to Escrow Agent.  If counsel is so retained,  the defendant or
defendants  in the lawsuit  shall bear the fees and  expenses of any  additional
counsel thereafter retained by it or them.

     8.14 Successor to Escrow Agent. If Escrow Agent is for any reason unwilling
or unable to serve as Escrow  Agent  during the term of this  Escrow  Agreement,
Escrow  Agent may  resign as Escrow  Agent by giving at least  thirty  (30) days
prior  written  notice  to  each  of  Acquiror,  Target  and  the  Shareholders'
Representative,  such resignation to be effective thirty (30) days following the
date such notice is given. In addition,  Acquiror,  Target and the Shareholders'
Representative  may jointly  remove the Escrow Agent as escrow agent at any time
with or without cause, by an instrument  (which may be executed in counterparts)
given to the Escrow Agent,  which  instrument shall designate the effective date
of such removal.  In the event of any such  resignation or removal,  a successor
escrow  agent  shall  be  appointed  by  Acquiror   with  the  approval  of  the
Shareholders' Representative, which approval shall not be unreasonably withheld.
Any such  successor  escrow  agent  shall  deliver to  Acquiror,  Target and the
Shareholders'  Representative a written  instrument  accepting such appointment,
and  thereupon it shall succeed to all the rights and duties of the escrow agent
hereunder  and shall be  entitled  to receive the assets in the Escrow Fund upon
five (5) days written notice to the parties.

     9.2 Interpretation. When a reference is made in this Agreement to Exhibits,
such  reference  shall  be to an  Exhibit  to this  Agreement  unless  otherwise
indicated.  The words  "include,"  "includes" and  "including"  when used herein
shall be deemed in each case to be followed by the words  "without  limitation."
In this Agreement, any reference to any event, change, condition or effect being
"material"  with  respect to any entity or group of entities  means any material
event,  change,  condition  or effect  related to the  condition  (financial  or
otherwise),  properties,  assets  (including  intangible  assets),  liabilities,
business,  operations  or  results  of  operations  of such  entity  or group of
entities.  In this Agreement,  any reference to a "Material Adverse Effect" with
respect to any  entity or group of  entities  means any event,  change or effect
that  is  materially   adverse  to  the  condition   (financial  or  otherwise),
properties,  assets  (including  intangible  assets),   liabilities,   business,
operations or results of operations of such entity and its  subsidiaries,  taken
as a whole. In this Agreement, any reference to a party's "knowledge" means such
party's actual knowledge after due and diligent  inquiry of officers,  directors
and other employees of such party and its  subsidiaries  reasonably  believed to
have  knowledge of such matters.  The phrase "made  available" in this Agreement
shall mean that the information referred to has been made available if requested
by the party to whom such information is to be made available.  The phrases "the
date of this Agreement",  "the date hereof", and terms of similar import, unless
the context otherwise  requires,  shall be deemed to refer to July __, 1998. The
table of contents and headings  contained in this  Agreement  are for  reference
purposes only and shall not affect in any way the meaning or  interpretation  of
this Agreement.

     9.3   Counterparts.   This  Agreement  may  be  executed  in  one  or  more
counterparts,  all of which shall be considered  one and the same  agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other  parties,  it being  understood  that all
parties need not sign the same counterpart.

     9.4 Entire Agreement;  No Third Party  Beneficiaries.  This Agreement,  the
other  Transaction  Documents  and  the  documents  and  instruments  and  other
agreements  specifically  referred  to  herein  or  delivered  pursuant  hereto,
including the Exhibits, the Schedules,  including the Target Disclosure Schedule
and the Acquiror  Disclosure  Schedule (a) constitute the entire agreement among
the parties with respect to the subject  matter  hereof and  supersede all prior
agreements  and  understandings,  both written and oral,  among the parties with
respect to the subject matter hereof, except for the Confidentiality  Agreement,
which shall continue in full force and effect, and shall survive any termination
of this  Agreement or the Closing,  in  accordance  with its terms;  (b) are not
intended  to confer  upon any other  person  any rights or  remedies  hereunder,
except for the rights of the Target  Shareholders  and  optionholders to receive
the  consideration  set forth in Article I of this Agreement and as set forth in
Sections 5.10 and 5.18.

     9.5 Severability. In the event that any provision of this Agreement, or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal,  void or  unenforceable,  the  remainder of this  Agreement  will
continue in full force and effect and the application of such provision to other
persons or  circumstances  will be  interpreted  so as  reasonably to effect the
intent of the parties hereto.  The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve,  to the extent  possible,  the  economic,  business and other
purposes of such void or unenforceable provision.

     9.6 Remedies  Cumulative.  Except as otherwise provided herein, any and all
remedies herein expressly  conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such party,  and the exercise by a party of any one remedy will not preclude the
exercise of any other remedy.

     9.7  Governing  Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State of California without regard to applicable
principles of conflicts of law. Each of the parties hereto irrevocably  consents
to  the  exclusive  jurisdiction  of any  court  located  within  the  State  of
California,  in  connection  with any matter  based upon or arising  out of this
Agreement or the matters contemplated herein,  agrees that process may be served
upon them in any manner  authorized by the laws of the State of  California  for
such persons and waives and covenants not to assert or plead any objection which
they might otherwise have to such jurisdiction and such process.

     9.8 Assignment.  Neither this Agreement nor any of the rights, interests or
obligations hereunder shall be assigned by any of the parties hereto (whether by
operation of law or otherwise)  without the prior  written  consent of the other
parties. Subject to the preceding sentence, this Agreement will be binding upon,
inure to the benefit of and be enforceable  by the parties and their  respective
successors and permitted assigns.

     9.9 Rules of  Construction.  The parties  hereto  agree that they have been
represented by counsel during the negotiation, preparation and execution of this
Agreement and, therefore, waive the application of any law, regulation,  holding
or rule of  construction  providing  that  ambiguities  in an agreement or other
document  will be  construed  against  the  party  drafting  such  agreement  or
document.

                          REGISTRATION RIGHTS AGREEMENT



                  THIS REGISTRATION  RIGHTS AGREEMENT is made as of the 30th day
of July,  1998,  (this  "Agreement")  by and between  Legato  Systems,  Inc.,  a
Delaware  corporation  (the  "Acquiror"),  and  each of the  persons  listed  on
Schedule A hereto (collectively, the "Stockholders").

                                    RECITALS

                  WHEREAS,  pursuant to an Agreement and Plan of  Reorganization
(the "Merger Agreement") dated as of July 30, 1998, by and among Acquiror, Aspen
Acquisition  Corp.,  a Minnesota  corporation  and wholly owned  subdivision  of
Acquiror (the "Merger Sub"), Software Moguls, Inc., a Minnesota corporation (the
"Target"),   Sunil  Khadilkar  (as  "Shareholders'  Agent,")  and  each  of  the
undersigned  stockholders  of the  Target  (each a  "Signing  Stockholder"  and,
collectively,  the  "Signing  Stockholders"),  the parties  thereto have agreed,
subject to the terms and conditions set forth therein,  to merge the Target with
and into  Merger Sub (the  "Merger")  and  thereby to convert  all shares of the
Target  Common  Stock (as such term is  defined in the  Merger  Agreement)  then
outstanding into shares of Acquiror Stock (as such term is defined in the Merger
Agreement);

                  WHEREAS,  the  Stockholders  desire  to  have  liquidity  with
respect to the shares of Acquiror Stock they receive in the Merger;

                  WHEREAS,  Acquiror  desires to grant each of the  Shareholders
registration  rights as  provided herein; and

                  NOW,  THEREFORE,  IN  CONSIDERATION  OF THE  PREMISES  AND THE
MUTUAL COVENANTS AND AGREEMENTS  HEREIN  CONTAINED,  THE PARTIES HEREBY AGREE AS
FOLLOWS:

1.       Registration Rights.  The Acquiror covenants and agrees as follows:

1.1      Definitions.  For purposes of this Section 1:

     (a) The term "Act" means the Securities Act of 1933, as amended.

     (b) The term "1934 Act" shall mean the Securities  Exchange Act of 1934, as
amended.

     (c) The  terms  "register,"  "registered,"  and  "registration"  refer to a
registration  effected  by  preparing  and filing a  registration  statement  or
similar  document in compliance with the Act, and the declaration or ordering of
effectiveness of such registration statement or document.

     (d) The  term  "Registrable  Securities"  means  the  Common  Stock  of the
Acquiror issued to the  Stockholders in the Merger,  and any Common Stock of the
Acquiror issued as a dividend or other  distribution with respect to such Common
Stock.

     (e) The term "Rule 144" shall mean Rule 144  promulgated  under the Act, as
amended,  or any similar  successor  rule thereto that may be promulgated by the
SEC.

     (f) The term "SEC" shall mean the Securities and Exchange Commission.

     (g) Capitalized  terms used, but not otherwise  defined,  in this Agreement
shall have the meanings given to them in the Merger Agreement.

1.2 Registration.

     (a) The Acquiror shall use all commercially reasonable efforts to effect as
soon  as  practicable  a  registration  statement  on Form  S-3 and any  related
qualification  or compliance with respect to all of the  Registrable  Securities
owned by Stockholders so as to permit or facilitate the sale and distribution of
the Stockholder's Registrable Securities as are specified by such Stockholder in
writing  upon  execution  hereof,  together  with  all or  such  portion  of the
Registrable  Securities  of any other  Stockholders  who have also  specified in
writing.

     (b)  Notwithstanding  the  foregoing,  if the Acquiror shall furnish to the
Stockholders a certificate signed by the Chief Financial Officer of the Acquiror
stating that in the good faith judgment of the Acquiror, it would be detrimental
to the  Acquiror  and its  stockholders  for such  registration  statement to be
filed,  and it is therefore  essential to defer the filing of such  registration
statement,  the Acquiror  shall have the right to defer filing the  registration
statement referred to in Section 1.2(a) until such time as the Acquiror believes
in its good faith  judgment that such filing would no longer be  detrimental  to
the Acquiror and its stockholders;  provided, however, the Acquiror shall not be
obligated to effect any  registration  pursuant to this Section 1 if Form S-3 is
not  available  for such  offering by the  Stockholders  or if the  Acquiror has
already effected one registration statement on Form S-3 for the Stockholders.


1.3  Obligations  of the  Acquiror.  Whenever  required  under this Section 1 to
effect the registration of any Registrable Securities, the Acquiror shall:

     (a) Prepare and file with the SEC, a registration statement with respect to
such Registrable Securities and use all commercially reasonable efforts to cause
such registration statement to become effective,  and, subject to the provisions
below, use commercially  reasonable efforts to, keep such registration statement
effective until the distribution  contemplated in the registration statement has
been completed. If at any time after a registration statement becomes effective,
the Acquiror advises the Stockholders in writing that the registration statement
shall  contain  any untrue  statement  of a  material  fact or omit to state any
material fact required to be stated  therein or necessary to make the statements
therein not misleading, or any prospectus comprising a part of such registration
statement shall contain any untrue statement of a material fact or omit to state
any  material  fact  required  to be stated  therein  or  necessary  to make the
statements  therein,  in light of the circumstances  under which they were made,
not  misleading  or  the  occurrence  or  existence  of  any  pending  corporate
development  that,  in the  reasonable  discretion  of the  Acquiror,  makes  it
appropriate to suspend the  availability of the  registration  statement and the
related prospectus,  the Acquiror shall give notice to the Stockholders that the
availability  of the  registration  statement is suspended and the  Stockholders
shall  suspend  any  further  sale of  Registrable  Securities  pursuant  to the
registration statement until the Stockholders have been informed in writing that
the  registration  statement is  available.  The  Acquiror  shall be entitled to
exercise its right to suspend the availability of the registration statement for
a period  exceeding not more than sixty (60) days in any three (3) month period,
not to exceed in the aggregate ninety (90) days in any twelve (12) month period.
When selling Registrable  Securities,  a Stockholder shall follow the procedures
set forth in Section 1.9 and may presume  that no  suspension  is in effect if a
trade is made in the manner described in that section.

     (b)  Subject  to  subsection  1.3(a),  prepare  and file  with the SEC such
amendments  and  supplements to such  registration  statement and the prospectus
used in  connection  with such  registration  statement  as may be  necessary to
comply with the  provisions  of the Act with respect to the  disposition  of all
securities covered by such registration statement.

     (c) Furnish to the  Stockholders  requesting  registration  such numbers of
copies of a prospectus,  including a preliminary prospectus,  in conformity with
the  requirements  of the Act, and such other  documents as they may  reasonably
request in order to facilitate the disposition of Registrable  Securities  owned
by them.

     (d) Use  commercially  reasonable  efforts  to  register  and  qualify  the
securities covered by such registration statement under such other securities or
Blue Sky laws of such  jurisdictions  as shall be  reasonably  requested  by the
Stockholders;  provided  that the Acquiror  shall not be required in  connection
therewith  or as a  condition  thereto to qualify  to do  business  or to file a
general  consent to service  of  process  in any such  states or  jurisdictions,
unless the  Acquiror  is already  subject  to service in such  jurisdiction  and
except as may be required by the Act.

1.4  Information  from  Stockholders.  It shall be a condition  precedent to the
obligations  of the Acquiror to take any action  pursuant to this Section 1 with
respect to the  Registrable  Securities of a Stockholder  that such  Stockholder
shall furnish to the Acquiror the information  requested on Appendix 1.4 hereto,
which  shall  include  such  information   regarding  himself  or  herself,  the
Registrable  Securities  held  by  him  or  her,  and  the  intended  method  of
disposition  of  such  securities,  and  such  other  information  as  shall  be
reasonably  requested by the Acquiror and required to effect the registration of
the Registrable Securities.

1.5  Expenses  of  Registration.  All  expenses  of  the  Stockholders,   except
underwriting  discounts (if any) or commissions,  including (without limitation)
all registration,  filing and qualification fees, printers' and accounting fees,
fees  and  disbursements  of  counsel  for the  Acquiror  shall  be borne by the
Acquiror;  provided, however, that the Acquiror shall not be required to pay any
professional fees incurred by any Stockholders.

1.6 No Assignment of  Registration  Rights.  The  registration  rights  provided
hereunder are not assignable.

1.7 Indemnification.  In the event any Registrable  Securities are included in a
registration statement under this Section 1:

     (a) Each Stockholder will indemnify and hold harmless the Acquiror, each of
its directors,  each of its officers who has signed the registration  statement,
each person,  if any,  who controls the Acquiror  within the meaning of the Act,
any other Stockholder selling securities in such registration  statement and any
controlling person of any such Stockholder, against any losses, claims, damages,
or  liabilities  (joint or  several) to which any of the  foregoing  persons may
become  subject,  under the Act, or the 1934 Act or other  federal or state law,
insofar as such losses,  claims,  damages, or liabilities (or actions in respect
thereto)  arise  out of or are  based  upon  any  of the  following  statements,
omissions or violations (collectively,  a "Violation"): (i) any untrue statement
or alleged untrue  statement of a material fact  contained in such  registration
statement,  including any preliminary  prospectus or final prospectus  contained
therein or any amendments or supplements  thereto,  (ii) any omission or alleged
omission to state  therein a material  fact  required to be stated  therein,  or
necessary to make the statements therein not misleading,  or (iii) any violation
or alleged  violation  by the  Acquiror of the Act, the 1934 Act, or any rule or
regulation  promulgated under the Act, or the 1934 Act or other federal or State
law, in each case to the extent that such  Violation is contained in any written
information  furnished by Stockholder  for inclusion in such  registration;  and
Stockholder  will  pay,  as  incurred,  any legal or other  expenses  reasonably
incurred by any person  intended to be indemnified  pursuant to this  subsection
1.7(a),  in connection  with  investigating  or defending any such loss,  claim,
damage,  liability, or action;  provided,  however, that the indemnity agreement
contained  in  this  subsection  1.7(a)  shall  not  apply  to  amounts  paid in
settlement  of any  such  loss,  claim,  damage,  liability  or  action  if such
settlement is effected  without the consent of Stockholder,  which consent shall
not be unreasonably  withheld;  provided,  that, in no event shall any indemnity
under this subsection  1.7(a) exceed the net proceeds from the offering received
by Stockholder.

     (b) Promptly after receipt by an  indemnified  party under this Section 1.7
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 1.7, deliver to the indemnifying party
a written notice of the commencement  thereof and the  indemnifying  party shall
have the right to participate in, and, to the extent the  indemnifying  party so
desires,  jointly with any other indemnifying party similarly noticed, to assume
the defense thereof with counsel mutually satisfactory to the parties; provided,
however,  that an indemnified party (together with all other indemnified parties
which may be represented  without  conflict by one counsel) shall have the right
to retain one  separate  counsel,  with the fees and  expenses to be paid by the
indemnifying  party, if  representation of such indemnified party by the counsel
retained  by the  indemnifying  party  would be  inappropriate  due to actual or
potential differing interests between such indemnified party and any other party
represented  by such  counsel  in such  proceeding.  

     (c) If the  indemnification  provided  for in this Section 1.7 is held by a
court of competent  jurisdiction to be unavailable to an indemnified  party with
respect to any loss,  liability,  claim, damage, or expense referred to therein,
then the  indemnifying  party, in lieu of indemnifying  such  indemnified  party
hereunder,  shall  contribute to the amount paid or payable by such  indemnified
party as a result of such loss,  liability,  claim,  damage,  or expense in such
proportion as is appropriate  to reflect the relative fault of the  indemnifying
party on the one hand and of the  indemnified  party on the other in  connection
with the statements or omissions that resulted in such loss,  liability,  claim,
damage, or expense as well as any other relevant equitable  considerations.  The
relative fault of the indemnifying  party and of the indemnified  party shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue  statement of a material  fact or the  omission to state a material  fact
relates to information  supplied by the indemnifying party or by the indemnified
party and the parties' relative intent,  knowledge,  access to information,  and
opportunity  to  correct  or  prevent  such  statement  or  omission.   

     (d) The  obligations  of each  Stockholder  under  this  Section  1.7 shall
survive  the  completion  of  any  offering  of  Registrable   Securities  in  a
registration statement under this Section 1, and otherwise.  

     (e)  Notwithstanding  the  foregoing,  to the extent that the provisions on
indemnification and contribution contained in an underwriting agreement (if any)
entered into in connection with the underwritten public offering are in conflict
with the foregoing  provisions,  the  provisions in the  underwriting  agreement
shall control.  

1.8 Termination of Registration Rights. The registration rights provided in this
Section 1 shall  terminate  with  respect  to a  particular  Stockholder  if the
Registrable  Securities  owned  by  such  Stockholder  have  been  held  for the
necessary holding period under Rule 144 and all shares of Registrable Securities
held by such Stockholder may be sold pursuant to Rule 144 in any three (3) month
period.  Upon the  termination of  registration  rights pursuant to this Section
1.8, the Acquiror shall have the right to withdraw the  registration  statement,
or any portion thereof, covering the Registrable Securities.

1.9 Notice by Selling Stockholders.  Each Stockholder who intends to sell any or
all of his shares of Registrable  Securities  pursuant to the provisions of this
Section 1 shall give advance  written notice to the Chief  Financial  Officer of
Acquiror,  of such  intention and shall be free to sell any or all of his shares
of Registrable  Securities if such  Stockholder  has not received  notice to the
contrary  within five (5)  business  days of the receipt by the Chief  Financial
Officer of Acquiror of such written notice.

2.       Miscellaneous.

2.1  General.  Nothing in this  Agreement,  express or  implied,  is intended to

or at such other  address as such party may  designate by ten (10) days' advance

Registrable Securities.

2.8  Severability.  If one or more  provisions of this  Agreement are held to be
unenforceable  under  applicable law, such provision shall be excluded from this
Agreement  and the  balance of the  Agreement  shall be  interpreted  as if such
provision  were so excluded  and shall be  enforceable  in  accordance  with its
terms.

2.9  Entire   Agreement.   This  Agreement   constitutes  the  full  and  entire
understanding  and  agreement  between  the  parties  with regard to the subject
hereof.

                              AFFILIATES AGREEMENT



                  THIS  AFFILIATES  AGREEMENT  (the  "Affiliates  Agreement") is
entered  into as of July 30,  1998  between  LEGATO  SYSTEMS,  INC.,  a Delaware
corporation ("Acquiror"), and the undersigned Stockholder (the "Stockholder") of
SOFTWARE MOGULS, INC., a Minnesota corporation (the "Target").

                                    RECITALS

                  A. The  Target,  Acquiror  and  Acquisition  Sub, a  Minnesota
corporation  and a wholly owned  subsidiary  of Acquiror  ("Merger  Sub"),  have
entered into an Agreement  and Plan of  Reorganization  dated July 30, 1998 (the
"Merger Agreement"), pursuant to which Merger Sub will be merged into the Target
(the  "Merger"),  and the  Target  will  become a  wholly  owned  subsidiary  of
Acquiror.

                  B.  Upon the  consummation  of the  Merger  and in  connection
therewith, the undersigned Stockholder will become the owner of shares of Common
Stock of Acquiror (the "Acquiror Shares").

                  C. The parties to the Merger  Agreement intend to adopt a plan
of reorganization within the meaning of Section 368 of the Internal Revenue Code
of 1986,  as amended (the "Code") and intend to cause the Merger to qualify as a
"reorganization"  under the  provisions  of  Section  368(a)(1)(A)  and  Section
368(a)(2)(E) of the Code.

                  D. The  parties  to the Merger  Agreement  intend to cause the
Merger to be accounted for as a pooling of interests.

                  NOW,  THEREFORE,  in  consideration  of the  premises  and the
mutual  agreements,  provisions and covenants set forth in the Merger  Agreement
and in this Affiliates Agreement, it is hereby agreed as follows:

1.       The undersigned Stockholder hereby agrees that:

     (a) The  undersigned  Stockholder  may be deemed to be (but does not hereby
admit to be) an  "affiliate"  of the Target within the meaning of Rule 145 under
the Securities Act of 1933, as amended (the  "Securities  Act"),  and Accounting
Series Release No. 130, as amended,  of the  Securities and Exchange  Commission
(the "SEC') ("Release No. 130").


     (b) The undersigned Stockholder will not sell, exchange,  transfer, pledge,
dispose of or otherwise  reduce the undersigned  Stockholder's  risk relative to
the Acquiror Shares or any part thereof until such time after the Effective Time
of the Merger as  financial  results  covering at least  thirty (30) days of the
combined  operations of Acquiror and the Target after the Effective  Time of the
Merger have been,  within the meaning of said Release No. 130, filed by Acquiror
with the SEC or  published  by  Acquiror  in an Annual  Report  on Form  10K,  a
Quarterly  Report on Form  10-Q,  a Current  Report  on Form  8-K,  a  quarterly
earnings report, a press release or other public issuance that includes combined
sales and income of the Target and Acquiror. Acquiror agrees to make such filing
or publication as soon as  practicable.  The  undersigned  will not,  during the
thirty (30) day period prior to the  Effective  Time of the Merger as determined
in Acquiror's reasonable discretion,  sell, exchange,  transfer, pledge, dispose
of or  otherwise  reduce the  undersigned  Stockholder's  risk  relative  to the
Acquiror  Shares or any part thereof  (including  any  disposition,  within such
period, of Stockholder's shares of the Target's Common Stock).

     (c) Except  with  respect to the  exchange of the Target  Common  Stock for
Acquiror  Common Stock pursuant to the Merger,  the  undersigned  has no current
plan or intent to engage in any sale of any Target capital stock (whether or not
acquired  pursuant  to the  exercise  of a stock  option)  on, or prior to,  the
Merger.  The  undersigned  shall  immediately  notify Acquiror and the Target in
writing via facsimile of any sale of Target capital stock by the undersigned on,
or prior to, the Merger.

     (d) Subject to  paragraphs  (b) and (c) of this Section 1, the  undersigned
Stockholder agrees not to offer, sell, exchange,  transfer,  pledge or otherwise
dispose  of any of the  Acquiror  Shares  unless at that time  either:  

     (i) such transaction is permitted pursuant to the provisions of Rule 145(d)
under the Securities Act;

     (ii)  counsel   representing   the  undersigned   Stockholder,   reasonably
satisfactory  to  Acquiror,  shall have  advised  Acquiror in a written  opinion
letter reasonably satisfactory to Acquiror and Acquiror's counsel and upon which
Acquiror and its counsel may rely, that no registration under the Securities Act
is required in connection with the proposed sale, transfer or other disposition;

     (iii) a  registration  statement  under the  Securities  Act  covering  the
Acquiror  Shares  proposed to be sold,  transferred  or  otherwise  disposed of,
describing  the  manner  and  terms  of the  proposed  sale,  transfer  or other
disposition, and containing a current prospectus, is filed with the SEC and made
effective under the Securities Act; or 

     (iv) an authorized  representative  of the SEC shall have rendered  written
advice to the undersigned  Stockholder (sought by the undersigned Stockholder or
counsel to the  undersigned  Stockholder,  with a copy  thereof and of all other
related  communications  delivered  to Acquiror) to the effect that the SEC will
take no  action,  or that the staff of the SEC will not  recommend  that the SEC
take action,  with  respect to the proposed  offer,  sale,  exchange,  transfer,
pledge or other  disposition if consummated.  

     (e) All certificates  representing  the Acquiror Shares  deliverable to the
undersigned  Stockholder pursuant to the Merger Agreement and in connection with
the Merger and any certificates  subsequently  issued with respect thereto or in
substitution  therefor shall,  unless one or more of the alternative  conditions
set forth in the  subparagraphs  of  paragraph  (d) of this Section 1 shall have
occurred, bear a legend substantially as follows:

                  "The  shares  represented  by  this  certificate  may  not  be
                  offered,  sold, exchanged,  transferred,  pledged or otherwise
                  disposed of except in accordance with the  requirements of the
                  Securities Act of 1933, as amended,  and the other  conditions
                  specified in that certain Affiliates  Agreement dated July 30,
                  1998, a copy of which Affiliates Agreement may be inspected by
                  the holder of this certificate at the offices of Acquiror,  or
                  Acquiror will furnish,  without charge,  a copy thereof to the
                  holder of this certificate upon written request therefor."

Acquiror,  at its  discretion,  may cause stop transfer orders to be placed with
its transfer agent with respect to the  certificates for the Acquiror Shares but
not as to the  certificates for any part of the Acquiror Shares as to which said
legend is no longer  appropriate when one or more of the alternative  conditions
set forth in the  subparagraphs  of  paragraph  (d) of this Section 1 shall have
occurred.

     (f) The undersigned Stockholder will observe and comply with the Securities
Act and the general rules and  regulations  thereunder,  as now in effect and as
from time to time amended and including those hereafter  enacted or promulgated,
in  connection  with  any  offer,  sale,  exchange,  transfer,  pledge  or other
disposition of the Acquiror Shares or any part thereof.

2. The undersigned Stockholder hereby represents and warrants that:

     (a)  Authorization.  Such Stockholder has full power and authority to enter
into this Agreement and such Agreement constitutes its valid and legally binding
obligation,  enforceable  in accordance  with its terms except (i) as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, and other laws of
general  application  affecting  enforcement of creditors'  rights generally and
(ii) as limited by laws relating to the  availability  of specific  performance,
injunctive relief, or other equitable remedies.

     (b) Purchase  Entirely for Own  Account.  This  Agreement is made with such
Stockholder in reliance upon such  Stockholder's  representation  to the Target,
which by such Stockholder's  execution of this Agreement such Stockholder hereby
confirms,  that the  Acquiror  Stock to be  received  by such  Stockholder  (the
"Securities")  will be  acquired  for  investment  for  such  Stockholder's  own
account,  not as a  nominee  or  agent,  and not  with a view to the  resale  or
distribution  of any part  thereof,  and that such  Stockholder  has no  present
intention of selling,  granting any participation in, or otherwise  distributing
the same. By executing this Agreement,  such Stockholder further represents that
such  Stockholder  does  not  have  any  contract,  undertaking,   agreement  or
arrangement with any person to sell,  transfer or grant  participations  to such
person or to any third person, with respect to any of the Securities.

     (c) Investment Experience. Such Stockholder is an investor in securities of
companies in the development  stage and acknowledges that it is able to fend for
itself, can bear the economic risk of its investment, and has such knowledge and
experience in financial or business matters that it is capable of evaluating the
merits  and  risks  of the  investment  in the  Securities.  If  other  than  an
individual,  Stockholder  also  represents  it has not  been  organized  for the
purpose of acquiring the Securities.

     (d) Accredited  Investor.  Such  Stockholder  is an  "accredited  investor"
within the meaning of  Securities  and Exchange  Commission  ("SEC") Rule 501 of
Regulation D, as presently in effect.

     (e) Restricted Securities. Such Stockholder understands that the Securities
it is purchasing are characterized as "restricted  securities" under the federal
securities  laws  inasmuch  as they are  being  acquired  from the  Target  in a
transaction  not  involving  a public  offering  and that  under  such  laws and
applicable  regulations such securities may be resold without registration under
the  Act,  only in  certain  limited  circumstances.  In this  connection,  such
Stockholder  represents  that it is familiar  with SEC Rule 144, as presently in
effect, and understands the resale limitations imposed thereby and by the Act.

     (f) Further  Representations by Foreign  Stockholders.  If a Stockholder is
not a United States person,  such Stockholder  hereby  represents that he or she
has satisfied himself or herself as to the full observance of the laws of his or
her  jurisdiction  in  connection  with  any  invitation  to  subscribe  for the
Securities or any use of this  Agreement,  including (i) the legal  requirements
within his  jurisdiction  for the purchase of the  Securities,  (ii) any foreign
exchange  restrictions  applicable to such purchase,  (iii) any  governmental or
other  consents that may need to be obtained,  and (iv) the income tax and other
tax  consequences,  if any,  that  may be  relevant  to the  purchase,  holding,
redemption, sale, or transfer of the Securities. Such Stockholder's subscription
and  payment  for,  and  his  or  her  continued  beneficial  ownership  of  the
Securities,  will not violate any applicable  securities or other laws of his or
her jurisdiction.

3. Reports.  From and after the Effective  Time of the Merger and for so long as
necessary in order to permit the  undersigned  Stockholder  to sell the Acquiror
Shares  pursuant to Rule 145 and, to the extent  applicable,  Rule 144 under the
Securities Act,  Acquiror will file on a timely basis all reports required to be
filed by it pursuant to Section 13 or 15(d) of the  Securities  Exchange  Act of
1934,  referred to in paragraph (c)(1) of Rule 144 under the Securities Act (or,
if applicable,  Acquiror will make publicly available the information  regarding
itself  referred  to in  paragraph  (c)(2) of Rule 144),  in order to permit the
undersigned  Stockholder  to sell,  pursuant to the terms and conditions of Rule
145 and the applicable provisions of Rule 144, the Acquiror Shares.

4. Waiver.  No waiver by any party  hereto of any  condition or of any breach of
any provision of this Affiliates Agreement shall be effective unless in writing.
5. Notices.  All notices,  requests,  demands or other  communications  that are

Re:  REGISTRATION STATEMENT ON FORM S-3


Ladies and Gentlemen:

         We have  examined the  Registration  Statement  on Form S-3  originally
filed by Legato  Systems,  Inc. (the "Company") with the Securities and Exchange
Commission (the  "Commission")  on September 29, 1998, as thereafter  amended or
supplemented (the "Registration Statement"), in connection with the registration
under the  Securities  Act of 1933, as amended,  of up to 249,999  shares of the
Company's Common Stock of certain stockholders of the Company (the "Shares"). As
your  counsel  in  connection  with  this  transaction,  we  have  examined  the
proceedings taken and are familiar with the proceedings  proposed to be taken by
you in connection with the sale and issuance of the Shares.

         It is our opinion that the Shares are legally and validly issued, fully
paid and non-assessable.

         We  consent  to the use of  this  opinion  as an  exhibit  to the  said
Registration  Statement,  and  further  consent to the use of our name  wherever
appearing in said Registration Statement,  including the prospectus constituting
a part thereof, and in any amendment or supplement thereto.

                                       Very truly yours,

                                      /s/ Gunderson Dettmer Stough Villeneuve

                       CONSENT OF INDEPENDENT ACCOUNTANTS

We consent to the  incorporation by reference in the  Registration  Statement on
Form S-3 of Legato Systems, Inc. (the "Company") for the registration of 249,999
shares of its common  shares,  of our reports  dated  January 19,  1998,  on our
audits of the consolidated financial statements and financial statement schedule
of the  Company  as of  December  31,  1997 and 1996,  and for the  years  ended
December 31,  1997,  1996 and 1995 which  reports are included in the  Company's
1997  Annual  Report  on Form  10-K,  filed  with the  Securities  and  Exchange
Commission.  We also  consent to the  reference  to our firm  under the  caption
