                                  THE COMPANY
 
   
    FaxSav Incorporated  ("FaxSav"  or  the  "Company")  designs,  develops  and
markets  a  variety  of  business-to-business  facsimile  transmission services,
including fax-to-fax, desktop-to-fax, enhanced  fax and broadcast fax  services.
FaxSav's  services are designed  to reduce the cost  of sending an international
fax while making  the process of  sending an international  fax easier and  less
time-consuming.   Through  the   use  of   its  integrated   Internet-based  and
telephony-based network and  its proprietary software,  the Company enables  its
customers  to  send documents  and  images to  fax  machines worldwide  at rates
substantially below the international rates charged by traditional long distance
carriers. Customers  are  offered  Internet  advantaged  pricing  for  facsimile
transmissions  to  targeted  markets  worldwide while  continuing  to  use their
traditional fax machines.  In addition, the  Company has developed  easy to  use
software  enabling customers to transmit  documents directly from their computer
desktops. FaxSav has  built a customer  base consisting of  over 7,200 small  to
medium  sized  businesses  with  international  fax  needs.  In  addition, there
currently are  more  than  1,000  registered  users  of  the  Company's  desktop
software.  In 1995,  the Company transmitted  more than 20.4  million minutes of
facsimile messages  yielding revenues  of $11.6  million. During  the first  six
months  of 1996, FaxSav  transmitted 13.8 million  minutes of facsimile messages
yielding revenues of $7.4 million, as  compared to 9.0 million minutes and  $5.0
million in revenue for the same six month period in 1995.
    
 
   
    The  Company  historically  has  provided  low  cost  facsimile  services by
utilizing pre-negotiated volume based arrangements with various telephony common
carriers. To  significantly  enhance the  cost  effectiveness of  the  Company's
transmission   services,  in  early  1996  FaxSav   began  to  deploy  a  global
Internet-based network  of nodes  that enable  it to  bypass the  long  distance
carriers' networks when sending faxes to or from international areas serviced by
these  nodes. In June 1996, FaxSav began  to utilize this integrated network for
commercial transmission of faxes over the Internet. FaxSav has deployed Internet
nodes in Bermuda, France, Germany, Hong Kong and the United Kingdom and plans to
deploy additional Internet nodes in key international telecommunications markets
by the end of 1997 to enable the  Company to route a majority of its  customers'
traffic  through the  Internet. The  Company believes  that this  planned global
Internet infrastructure,  which is  designed to  integrate seamlessly  with  its
existing  telephony-based  network,  will  enable  the  Company  to  bypass long
distance carrier  networks  for  transmissions originating  and  terminating  in
countries  where such nodes have been  deployed, thereby reducing its customers'
international transmission costs.  FaxSav believes that  this integrated  global
network   will  enable  the   Company  to  emerge  as   a  leading  supplier  of
comprehensive, low cost global facsimile services.
    
 
    The  Company's  services  are  targeted  to  customers  with   international
facsimile  transmission  requirements.  FaxSav  offers  a  variety  of  services
designed  to  meet  the  individual  business  requirements  of  its  customers,
including  real-time, "virtual real-time"  (immediate delivery attempt following
receipt of  the  customer's  document  by  the  FaxSav  network)  and  broadcast
services.   Specifically,  customers  may  utilize:   FAXSAV,  a  real-time  fax
transmission  through  FaxSav's  telephony-based  network;  FAXSAV  ASSURED,   a
"virtual   real-time"  enhanced   delivery  service  option   which  shifts  the
responsibility for repetitive completion attempts to the FaxSav network;  FAXSAV
EZ-LIST,  a fax-to-fax broadcast service  which allows a message  to be faxed to
multiple recipients by a single transmission to the FaxSav network; FAXSAV PLUS,
the Company's new "virtual  real-time" service which  utilizes a combination  of
FaxSav's traditional telephony-based network and
 
                                       3
<PAGE>
its  growing  Internet-based  network;  and, FAXSAV  FOR  INTERNET,  a  suite of
services enabling customers to send faxes directly from their computer  desktops
(either  through  e-mail  or a  Windows  software application)  to  fax machines
worldwide. FaxSav also  provides customized solutions  designed for high  volume
fax applications.
 
    Access to the FaxSav network is accomplished easily and does not require any
initial  investment, installation expense or change in business practices by the
customer. Customers connect to the FaxSav network by simply plugging the  FAXSAV
CONNECTOR,  a  small  proprietary  device, between  their  fax  machine  and the
telephone jack. In  the first  half of  1996, FaxSav  further expanded  customer
access  options by introducing desktop software which can easily be installed on
Internet-connected personal  computers  and  which  enables  customers  to  send
documents  and images directly  to fax machines  worldwide. Customers can deploy
FaxSav's services  at  individual  fax machines  or  desktop  locations,  across
departments   or  throughout  organizations   using  this  modular  installation
approach. The  Company  sells  its services  through  multiple  sales  channels,
including direct mail and telemarketing programs, a direct field sales force, an
agent and dealer distribution network and promotional activities.
 
    FaxSav  was incorporated  in Delaware  on November  29, 1989  under the name
Digitran Corporation and changed its name to FaxSav Incorporated on February 28,
1996. The  Company's  executive offices  are  located at  399  Thornall  Street,
Edison,  New  Jersey  08837 and  its  telephone  number is  (908)  906-2000. The
Company's Internet address is http://www.faxsav.com.

                                  RISK FACTORS
 
    IN  ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING RISK
FACTORS SHOULD  BE  CAREFULLY  CONSIDERED  IN EVALUATING  THE  COMPANY  AND  ITS
BUSINESS BEFORE PURCHASING SHARES OF COMMON STOCK OFFERED HEREBY.
 
    HISTORY  OF OPERATING  LOSSES; ACCUMULATED DEFICIT.   From  its inception in
1989 through  the  six-month  period  ended  June  30,  1996,  the  Company  has
experienced  significant operating losses. The Company incurred operating losses
of $3.3 million, $3.6 million and  $4.1 million during the years ended  December
31,  1993, 1994 and 1995,  respectively, and $3.5 million  during the six months
ended June  30,  1996.  The  Company  currently  anticipates  incurring  further
operating  losses as  it attempts  to expand  its business  and there  can be no
assurance that its future operations will generate positive operating income. As
of June 30, 1996, the Company had an accumulated deficit of $21.0 million.
 
   
    The Company  has  generated net  operating  loss ("NOL")  carryforwards  for
income  tax purposes of  approximately $16.1 million  through December 31, 1995.
These  NOL  carryforwards  have  been  recorded  as  a  deferred  tax  asset  of
approximately $3.8 million. Based upon the Company's history of operating losses
and  presently known factors,  management has determined that  it is more likely
than not that the Company will  be unable to generate sufficient taxable  income
prior  to the expiration of these  NOL carryforwards and has accordingly reduced
its  deferred  tax  assets  to  zero  with  a  full  valuation  allowance.   See
"Management's  Discussion  and Analysis  of Financial  Condition and  Results of
Operations--Liquidity and Capital Resources."
    
 
   
    QUARTERLY FLUCTUATIONS; POSSIBLE VOLATILITY OF STOCK PRICE.  The Company may
in the  future experience  significant quarter  to quarter  fluctuations in  its
results  of  operations, which  may result  in  volatility in  the price  of the
Company's Common  Stock. Quarterly  results  of operations  may fluctuate  as  a
result of a variety of factors, including demand for the Company's services, the
introduction  of new  services and  service enhancements  by the  Company or its
competitors, market  acceptance of  new services,  the mix  of revenues  between
Internet-based  versus  telephony-based  deliveries, the  timing  of significant
marketing programs, the number and timing of the hiring of additional personnel,
competitive conditions  in the  industry and  general economic  conditions.  The
Company's  revenues  are  difficult  to  forecast.  Shortfalls  in  revenues may
adversely and  disproportionately affect  the  Company's results  of  operations
because  a high  percentage of the  Company's operating  expenses are relatively
fixed, and  planned  expenditures, such  as  the anticipated  expansion  of  the
Company's  Internet infrastructure, are  based primarily on  sales forecasts. In
addition, the stock market in general  has experienced extreme price and  volume
fluctuations,  as evidenced by the fluctuations in the Nasdaq National Market in
July 1996, which have affected the market price of securities of many  companies
in  the  telecommunications  and  technology  industries  and  which  have  been
unrelated  to  the  operating  performance  of  such  companies.  These   market
fluctuations  may  adversely affect  the market  price  of the  Company's Common
Stock. Accordingly, the Company  believes that period  to period comparisons  of
results  of operations are  not necessarily meaningful and  should not be relied
upon as an indication of future results of operations. There can be no assurance
that the Company will be profitable in any future quarter. Due to the  foregoing
factors,  it  is  likely that  in  one  or more  future  quarters  the Company's
operating results will be below the  expectations of public market analysts  and
investors.  Such an event would  have a material adverse  effect on the price of
the Company's  Common  Stock.  See  "Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations--Quarterly Results."
    
 
    DEPENDENCE   ON   NETWORK   INFRASTRUCTURE;  NO   ASSURANCE   OF  SUCCESSFUL
INTERNET-CAPABLE NODE DEPLOYMENT.  The Company's future  success will depend  in
part  upon the capacity, reliability and  security of its network infrastructure
and in  particular upon  its  ability to  successfully deploy  an  international
network of Internet-capable facsimile nodes. The Company must continue to expand
and  adapt its network infrastructure as the  number of customers and the volume
of traffic they wish to transmit increases. The expansion and adaptation of  the
Company's network infrastructure will require substantial financial, operational
and  management resources. There  can be no  assurance that the  Company will be
able to expand or adapt its network infrastructure to meet any additional demand
on a timely basis, at  a commercially reasonable cost,  or at all. In  addition,
the  Company anticipates  that implementation  of its  price leadership strategy
generally will cause
 
                                       6
<PAGE>
its overall gross profit margin to be  reduced until a sufficient number of  key
international  telecommunications markets  are serviced  by its Internet-capable
facsimile nodes. There  can be no  assurance that  the Company will  be able  to
deploy  the contemplated Internet-capable  facsimile node expansion  on a timely
basis, at a commercially reasonable cost, or at all. Any failure of the  Company
to  expand its network infrastructure on a timely basis, to adapt it to changing
customer  requirements  or  evolving  industry   standards  or  to  deploy   the
contemplated  Internet-capable facsimile node infrastructure  on a timely basis,
or at  all, would  have a  material adverse  effect on  the Company's  business,
financial  condition  and  results  of  operations.  Further,  there  can  be no
assurance that the Company will be  able to satisfy the regulatory  requirements
in  each  of the  countries currently  targeted for  node deployment,  which may
prevent the Company  from installing  Internet-capable facsimile  nodes in  such
countries  and may  have a  material adverse  effect on  the Company's business,
operating results and  financial condition. See  "Business--The FaxSav  Network"
and "--Government Regulation."
 
   
    DEPENDENCE  ON THE INTERNET AS A FACSIMILE TRANSMISSION MEDIUM.  The Company
believes that  its  future success  will  depend in  part  upon its  ability  to
significantly  expand its base  of Internet-capable nodes and  route more of its
customers' traffic  through the  Internet. The  Company's success  is  therefore
largely  dependent  upon the  viability  of the  Internet  as a  medium  for the
transmission of documents. To date, the Company has transmitted a limited amount
of customer traffic over the  Internet, and there can  be no assurance that  the
Internet  will  prove  to  be  a  viable  communications  medium,  that document
transmission over  the  Internet will  be  reliable or  that  Internet  capacity
constraints  will not develop which inhibit efficient document transmission. The
Company accesses  the  Internet from  its  Internet-capable nodes  by  dedicated
connection  to third  party internet service  providers. The  Company pays fixed
monthly fees for such Internet access, regardless of the Company's usage or  the
volume  of its customers'  traffic. There can  be no assurance  that the current
pricing structure  for  access  to and  use  of  the Internet  will  not  change
unfavorably.  If the Internet  proves to be an  impractical or unreliable medium
for document  transmissions, if  material capacity  constraints develop  on  the
Internet  or  the current  Internet pricing  structure changes  unfavorably, the
Company's business,  financial  condition and  results  of operations  would  be
materially and adversely affected.
    
 
   
    NO  ASSURANCE OF MARKET ACCEPTANCE.  The Company's ability to route existing
customers' traffic through the Internet and  to sell its FAXSAV PLUS service  to
new  customers may be inhibited by, among  other factors, the reluctance of some
customers to switch from real-time fax delivery to "virtual real-time"  delivery
and  by widespread  concerns over  the adequacy of  security in  the exchange of
information over  the  Internet.  The  Company  currently  relies  on  RSA  Data
Security,  Inc.  ("RSA") standard  encryption  technology to  enable  the secure
transfer of customer documents over the Internet. There can be no assurance that
advances in computer capabilities, new discoveries in the field of  cryptography
or other events or developments will not result in a compromise or breach of the
RSA  encryption technology  or other algorithms  used by the  Company to protect
customer data. If the Company's existing  and potential customers do not  accept
"virtual  real-time" delivery  through the  Internet as  a means  of sending and
receiving documents via fax, or if any compromise of the Company's security were
to occur, the Company's business, financial condition and results of  operations
would be materially and adversely affected.
    
 
    INTENSE  COMPETITION.   The  market for  facsimile transmission  services is
intensely competitive  and there  are  limited barriers  to entry.  The  Company
expects that competition will intensify in the future. The Company believes that
its  ability  to compete  successfully  will depend  upon  a number  of factors,
including market presence; the capacity, reliability and security of its network
infrastructure; the  pricing  policies of  its  competitors and  suppliers;  the
timing  of introductions of new services and service enhancements by the Company
and its competitors; and industry and general economic trends.
 
    The Company's current  and prospective competitors  generally fall into  the
following  groups: (i) telecommunication companies, such as AT&T Corp. ("AT&T"),
MCI Communications Corp., Inc. ("MCI"),  Sprint Corp. ("Sprint"), LDDS  WorldCom
Inc.   ("LDDS  WorldCom")  and  the  regional  Bell  operating  companies;  (ii)
telecommunications resellers, such as  Frontier Corporation, Biztel  Corporation
and Eastern Telecom Corporation; (iii) Internet service providers, such as Uunet
Technologies, Inc. and
 
                                       7
<PAGE>
NETCOM  On-Line Communications Services, Inc.,  (iv) on-line services providers,
such as America  Online, Inc.  and CompuServe  Incorporated and  (v) direct  fax
delivery  competitors, including  Xpedite Systems,  Inc. and  Fax International,
Inc. Many of  these competitors  have greater market  presence, engineering  and
marketing  capabilities,  and financial,  technological and  personnel resources
than those available to the  Company. As a result, they  may be able to  develop
and  expand their communications and network infrastructures more quickly, adapt
more  swiftly  to  new  or   emerging  technologies  and  changes  in   customer
requirements,  take  advantage  of  acquisition  and  other  opportunities  more
readily, and  devote  greater resources  to  the  marketing and  sale  of  their
products  and  services than  can the  Company. Further,  the foundation  of the
Company's telephony  network infrastructure  consists of  the right  to use  the
telecommuni-
cations  lines  of  several  of  the  above-mentioned  long  distance  carriers,
including LDDS WorldCom and MCI. There can be no assurance that these  companies
will  not discontinue or otherwise alter their relationships with the Company in
a manner that would have a material adverse effect upon the Company's  business,
financial  condition  and  results  of  operations.  In  addition,  current  and
potential  competitors   have   established   or   may   establish   cooperative
relationships  among themselves or with third parties to increase the ability of
their services to  address the needs  of the Company's  current and  prospective
customers.  Accordingly, it is possible that  new competitors or alliances among
competitors may emerge and rapidly acquire significant market share. In addition
to direct competitors, many of the Company's larger potential customers may seek
to internally fulfill their  fax communication needs  through the deployment  of
their own computerized fax communications systems or network infrastructures for
intra-company faxing.
 
    Increased  competition is  likely to  result in  price reductions  and could
result in reduced gross margins and  erosion of the Company's market share,  any
of  which  would  have a  material  adverse  effect on  the  Company's business,
financial condition and results  of operations. There can  be no assurance  that
the  Company  will be  able to  compete successfully  against current  or future
competitors or  that competitive  pressures  will not  have a  material  adverse
effect on the Company's business, financial condition and results of operations.
 
    NO  ASSURANCE OF SUCCESSFUL  MANAGEMENT OF GROWTH.   The Company has rapidly
and significantly  expanded  its  operations and  anticipates  that  significant
expansion  will continue  to be  required in  order to  address potential market
opportunities. The Company anticipates significantly increasing the size of  its
sales  and marketing efforts following the  completion of this offering, and the
Company also will be required to increase its customer support staff. There  can
be  no assurance that such  expansion will be successfully  completed or that it
will generate sufficient revenues to cover the Company's expenses. The inability
of the Company to promptly address and respond to these circumstances could have
a material adverse  effect on  the Company's business,  financial condition  and
results of operations.
 
    RAPID  INDUSTRY CHANGE.  The telecommunications industry in general, and the
facsimile transmission business  in particular, are  characterized by rapid  and
continuous   technological   change.  Future   technological  advances   in  the
telecommunications industry may result  in the availability  of new services  or
products that could compete with the facsimile transmission services provided by
the  Company or reduce the  cost of existing products  or services, any of which
could enable the Company's existing or potential customers to fulfill their  fax
communications  needs more cost efficiently. There  can be no assurance that the
Company will be successful in developing and introducing new services that  meet
changing  customer  needs  and  respond  to  technological  changes  or evolving
industry standards  in  a  timely  manner,  if  at  all,  or  that  services  or
technologies  developed  by  others  will  not  render  the  Company's  services
noncompetitive. The  inability of  the  Company to  respond to  changing  market
conditions,  technological developments, evolving industry standards or changing
customer requirements, or  the development of  competing technology or  products
that  render the Company's services noncompetitive would have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business--Services."
 
    RISK OF  SYSTEM  FAILURE; SECURITY  RISKS.   The  Company's  operations  are
dependent on its ability to protect its network from interruption by damage from
fire,  earthquake, power  loss, telecommunications  failure, unauthorized entry,
computer viruses  or other  events beyond  the Company's  control. Most  of  the
Company's  current  computer  hardware and  switching  equipment,  including its
processing equipment,  is  currently located  at  two  sites. There  can  be  no
assurance   that   the   Company's   existing   and   planned   precautions   of
 
                                       8
<PAGE>
backup systems, regular data  backups and other procedures  will be adequate  to
prevent   significant  damage,  system   failure  or  data   loss.  Despite  the
implementation of security  measures, the Company's  infrastructure may also  be
vulnerable to computer viruses, hackers or similar disruptive problems caused by
its  customers or other  Internet users. Persistent  problems continue to affect
public  and  private  data  networks,  including  computer  break-ins  and   the
misappropriation  of confidential information. Such computer break-ins and other
disruptions may jeopardize the security of information stored in and transmitted
through the  computer  systems  of the  individuals,  businesses  and  financial
institutions  utilizing the Company's services,  which may result in significant
liability to the Company and also  may deter potential customers from using  the
Company's   services.  Any  damage,  failure  or  security  breach  that  causes
interruptions or  data loss  in  the Company's  operations  or in  the  computer
systems  of its customers could have a  material adverse effect on the Company's
business, financial condition and results of operations.
 
   
    DEPENDENCE UPON SUPPLIERS; SOLE AND LIMITED SOURCES OF SUPPLY.  The  Company
relies  on third parties to supply key components of its network infrastructure,
including long distance telecommunications services and telecommunications  node
equipment,  many of which are available only  from sole or limited sources. LDDS
WorldCom, MCI  and  Telstra  Corporation Limited  ("Telstra")  are  the  primary
providers   of  long  distance  telecommunications   services  to  the  Company.
Approximately 94%,  91%  and 77%  of  the Company's  telecommunications  traffic
passed  through  communications  lines  of  LDDS  WorldCom  and  its predecessor
companies for the six months  ended June 30, 1996 and  the years ended 1995  and
1994,  respectively.  The  Company  has  from  time-to-time  experienced partial
interruptions  of  service  from  its  telecommunications  carriers  which  have
temporarily  prevented customers in limited geographical areas from reaching the
FaxSav network. There can be no  assurance that the Company will not  experience
partial  or complete service interruptions in the  future. The fixed term of the
Company's contract with LDDS WorldCom expires  on October 31, 1996, after  which
date  the contract will continue on a month-to-month basis until renegotiated by
the parties or terminated by either party.  There can be no assurance that  LDDS
WorldCom  and the Company's other  telecommunications providers will continue to
provide long distance services to the Company at attractive rates, or at all, or
that the Company will be able to  obtain such services in the future from  these
or  other  long distance  providers  on the  scale  and within  the  time frames
required by the Company. Any failure to  obtain such services on a timely  basis
at  an affordable  cost, or any  significant delays or  interruptions of service
from such  carriers, would  have  a material  adverse  effect on  the  Company's
business, financial condition and results of operations.
    
 
    All  of the  faxboards used  in the  Company's telecommunications  nodes are
supplied by Brooktrout  Technology, Inc. ("Brooktrout").  The Company  purchases
Brooktrout faxboards on a non-exclusive basis pursuant to purchase orders placed
from  time-to-time,  carries  a  limited  inventory  of  faxboards  and  has  no
guaranteed supply arrangement with Brooktrout. In addition to faxboards, many of
the routers,  switches  and other  hardware  components used  in  the  Company's
network   infrastructure  are  supplied   by  sole  or   limited  sources  on  a
non-exclusive, purchase order basis. There  can be no assurance that  Brooktrout
or the Company's other suppliers will not enter into exclusive arrangements with
the  Company's competitors, or cease selling  these components to the Company at
commercially reasonable  prices, or  at all.  The anticipated  expansion of  the
Company's  network infrastructure is  expected to place  a significant demand on
the Company's suppliers,  some of  which have limited  resources and  production
capacity. In addition, certain of the Company's suppliers, in turn, rely on sole
or  limited sources of supply for components included in their products. Failure
of the Company's suppliers to adjust to meet such increasing demand may  prevent
them  from continuing  to supply components  and products in  the quantities and
quality and at  the times  required by  the Company,  or at  all. The  Company's
inability  to obtain sufficient quantities of  sole or limited source components
or to  develop  alternative sources  if  required  could result  in  delays  and
increased  costs in the expansion of  the Company's network infrastructure or in
the  inability  of  the  Company  to  properly  maintain  the  existing  network
infrastructure,  which would  have a  material adverse  effect on  the Company's
business, financial condition and results of operations.
 
    LIMITED PROTECTION  OF INTELLECTUAL  PROPERTY RIGHTS;  RISK OF  THIRD  PARTY
CLAIMS OF INFRINGEMENT.  The Company's success is dependent upon its proprietary
technology. The Company relies primarily on a
 
                                       9
<PAGE>
combination   of  contract,   copyright  and   trademark  law,   trade  secrets,
confidentiality agreements and contractual provisions to protect its proprietary
rights. The Company has patent applications pending for its FAXSAV CONNECTOR and
for its  "e-mail Stamps"  security technology  incorporated into  its  FAXMAILER
service.   There  can  be  no  assurance  that  patents  will  issue  from  such
applications  or  that  present  or  future  patents  will  provide   sufficient
protection  to  the  Company's  present  or  future  technologies,  services and
processes. In  addition,  there  can  be  no  assurance  that  others  will  not
independently develop substantially equivalent proprietary information or obtain
access  to the Company's know-how. Despite  the Company's efforts to protect its
proprietary rights,  unauthorized parties  may attempt  to copy  aspects of  the
Company's  services or to obtain and use information that the Company regards as
proprietary. In addition, the laws of some foreign countries do not protect  the
Company's  proprietary rights to  the same extent  as do the  laws of the United
States. There can be no assurance that the steps taken by the Company to protect
its proprietary rights will be adequate  or that the Company's competitors  will
not  independently  develop technologies  that  are substantially  equivalent or
superior to the Company's technologies.
 
    The Company  is not  aware that  any of  its services,  trademarks or  other
proprietary  rights infringe the  proprietary rights of  third parties. However,
the Company received  a letter in  the third  quarter of 1995  stating that  the
Company's  FAXSAV  CONNECTOR  may  be  utilizing  a  call  diversion methodology
patented by such correspondent. To the Company's knowledge, such third party has
not initiated  a  suit, action,  proceeding  or investigation  relating  to  any
alleged  infringement by the Company  of such patent. There  can be no assurance
that this or other third parties will not assert infringement claims against the
Company in  the  future.  Patents  have been  granted  recently  on  fundamental
technologies  in the communications and desktop  software areas, and patents may
issue which relate  to fundamental  technologies incorporated  in the  Company's
services. As patent applications in the United States are not publicly disclosed
until  the patent issues, applications  may have been filed  which, if issued as
patents, could  relate  to  the  Company's services.  The  Company  could  incur
substantial  costs and  diversion of  management resources  with respect  to the
defense of any claims that the Company has infringed upon the proprietary rights
of others, which costs and diversion could have a material adverse effect on the
Company's business, financial condition and results of operations.  Furthermore,
parties making such claims could secure a judgment awarding substantial damages,
as  well as injunctive  or other equitable relief  which could effectively block
the Company's ability to license and sell  its services in the United States  or
abroad.  Any such judgment could have a material adverse effect on the Company's
business, financial condition and  results of operations. In  the event a  claim
relating  to  proprietary  technology  or information  is  asserted  against the
Company, the Company may seek licenses to such intellectual property. There  can
be no assurance, however, that licenses could be obtained on terms acceptable to
the  Company, or at all.  The failure to obtain  any necessary licenses or other
rights could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
    RISK OF SOFTWARE DEFECTS OR DEVELOPMENT DELAYS.  Software-based services and
equipment, such as the Company's FAXSAV  FOR INTERNET suite of services and  the
FAXSAV  CONNECTOR, may contain undetected errors  or failures when introduced or
when new versions are released. There can be no assurance that, despite  testing
by  the Company and by current and potential customers, errors will not be found
in such software or other  releases after commencement of commercial  shipments,
or  that the Company will not experience development delays, resulting in delays
in the shipment of software and a loss of or delay in market acceptance, any  of
which  could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
    DEPENDENCE ON KEY PERSONNEL.   The Company's  future performance depends  in
significant  part upon  the continued  service of  its key  technical, sales 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 executive officers or
other key  employees could  have  a material  adverse  effect on  the  Company's
business,  financial condition and  results of operations.  The Company's future
success also depends  on its  continuing ability  to attract  and retain  highly
qualified  technical,  sales  and  managerial  personnel.  Competition  for such
personnel is intense, and there can be no assurance that the Company can  retain
its  key  technical, sales  and  managerial employees  or  that it  can attract,
assimilate or  retain other  highly qualified  technical, sales  and  managerial
personnel in the future. See "Management."
 
                                       10
<PAGE>
    RISKS  RELATED TO  POTENTIAL ACQUISITIONS.   The  Company may  in the future
pursue acquisitions of complementary services or product lines, technologies  or
businesses,  although the Company has  no present understandings, commitments or
agreements with respect  to any  such acquisitions. Future  acquisitions by  the
Company could result in potentially dilutive issuances of equity securities, the
incurrence  of debt and contingent liabilities and amortization expenses related
to goodwill and other intangible assets, which could materially adversely affect
the Company's  business,  financial  condition and  results  of  operations.  In
addition,  acquisitions involve  numerous risks,  including difficulties  in the
assimilation of  the  operations, technologies,  services  and products  of  the
acquired  companies  and  the  diversion of  management's  attention  from other
business concerns. In the event that  any such acquisition were to occur,  there
can be no assurance that the Company's business, financial condition and results
of operations would not be materially adversely affected.
 
    RELIANCE  ON  INTERNATIONAL STRATEGIC  ALLIANCES.   The  Company  intends to
establish and build an  international customer base  by forming strategic  sales
and    marketing   alliances   with    foreign   Internet   service   providers,
telecommunications companies and resellers. There  can be no assurance that  the
Company  will  be  able to  form  or,  if formed,  maintain  any  such strategic
alliances. The Company's  success in developing  an international customer  base
depends  not only on the formation of such  alliances but also on the success of
these partners and their ability to successfully market the Company's  services.
The  failure to  form and  maintain such strategic  alliances or  the failure of
these partners to successfully  develop and sustain a  market for the  Company's
service  will  have  a  material  adverse effect  on  the  Company's  ability to
establish and build an international customer base, which could have a  material
adverse  effect on  the Company's business,  financial condition  and results of
operations.
 
    GOVERNMENT REGULATION.  The Company is subject to regulation by the  Federal
Communications  Commission  (the "FCC"),  by  various state  public  service and
public utility commissions and by various international regulatory authorities.
 
    FaxSav is licensed by  the FCC as  an authorized telecommunications  company
and  is classified as a "non-dominant interexchange carrier." Generally, the FCC
has chosen not to exercise its  statutory power to closely regulate the  charges
or   practices  of  non-dominant  carriers.  Nevertheless,  the  FCC  acts  upon
complaints  against  such  carriers  for   failure  to  comply  with   statutory
obligations  or with the FCC's rules, regulations and policies. The FCC also has
the power to impose more stringent regulatory requirements on the Company and to
change its regulatory  classification. There can  be no assurance  that the  FCC
will not change the Company's regulatory classification or otherwise subject the
Company to more burdensome regulatory requirements.
 
    In  connection with the anticipated  deployment of Internet-capable nodes in
countries throughout  the world,  the  Company will  be  required to  satisfy  a
variety  of foreign regulatory requirements. The  Company intends to explore and
seek to comply  with these  requirements on  a country-by-country  basis as  the
deployment  of  Internet-capable  facsimile  nodes continues.  There  can  be no
assurance that the Company will be  able to satisfy the regulatory  requirements
in each of the countries currently targeted for node deployment, and the failure
to  satisfy such requirements may prevent  the Company from installing Internet-
capable facsimile nodes  in such countries.  The failure to  deploy a number  of
such  nodes  could have  a material  adverse effect  on the  Company's business,
operating results and financial condition.
 
   
    The Company's  nodes  and its  FAXLAUNCHER  service utilize  RSA  encryption
technology  in connection  with the  routing of  customer documents  through the
Internet. The export of  such encryption technology is  regulated by the  United
States  government.  The Company  is seeking  authority for  the export  of such
encryption technology and anticipates that  authority will be granted to  export
such  technology worldwide, other than to  Cuba, Iran, Libya, North Korea, Sudan
and Syria. Nevertheless, there can be  no assurance that such authority will  be
granted  or, if granted, that it will not be revoked or modified at any time for
any particular  jurisdiction  or  in  general. In  addition,  there  can  be  no
assurance  that such export controls, either in  their current form or as may be
subsequently enacted, will  not limit  the Company's ability  to distribute  its
services outside of the United States or electronically. While the Company takes
precautions  against unlawful exportation of its  software, the global nature of
the Internet makes it virtually impossible to
    
 
                                       11
<PAGE>
effectively control the distribution of  its services. Moreover, future  Federal
or  state legislation  or regulation may  further limit levels  of encryption or
authentication  technology.   Any  such   export  restrictions,   the   unlawful
exportation  of the Company's  services, or new  legislation or regulation could
have a material adverse  effect on the  Company's business, financial  condition
and results of operations.
 
   
    SHARES  ELIGIBLE FOR FUTURE SALE.  Sales of substantial numbers of shares of
Common Stock in the public market after this offering could adversely affect the
market price of the Common Stock. Upon completion of this offering, the  Company
will  have outstanding  10,370,490 shares  of Common  Stock. In  addition to the
2,200,000 shares of Common Stock offered hereby, as of the effective date of the
Registration Statement of  which this  Prospectus forms a  part (the  "Effective
Date"), there will be 8,170,490 shares of Common Stock outstanding, all of which
are  "restricted securities" under  the Securities Act.  Certain stockholders of
the Company are subject to lock-up agreements providing generally that they will
not offer, sell, contract to sell or  otherwise dispose of any shares of  Common
Stock  or any  securities convertible  or exchangeable  into Common  Stock for a
period of 180 days after the date  of this Prospectus without the prior  written
consent of Lehman Brothers Inc., which may be given at any time, without notice,
with respect to all or any portion of such shares. Certain other stockholders of
the  Company are subject to similar restrictions contained in an Investor Rights
Agreement. Taking  into  account  the  lock-up  agreements  and  notwithstanding
possible  earlier eligibility for  resale under the provisions  of Rules 144 and
701, the numbers of shares that will be available for sale in the public  market
will  be as follows.  Beginning 90 days after  the Effective Date, approximately
63,000 shares of restricted  securities will become eligible  for resale in  the
public  market.  Beginning  180  days after  the  Effective  Date, approximately
5,950,000 additional shares  of restricted securities  will become eligible  for
sale in the public market upon expiration of certain lock-up agreements pursuant
to Rule 144 and, as of that date, approximately 5,300,000 of such shares will be
subject  to certain volume  and other resale restrictions  pursuant to Rules 144
and 701. The Securities and Exchange Commission has proposed certain  amendments
to Rule 144 which would reduce the holding period required before shares subject
to  Rule 144 become eligible for resale  in the public market. This proposal, if
adopted, would  significantly increase  the number  of shares  of the  Company's
Common  Stock  eligible for  immediate resale  following  the expiration  of the
lock-up agreements.
    
 
   
    The holders  of  approximately 8,017,000  shares  of Common  Stock  and  the
holders  of warrants  to purchase an  additional 138,385 shares  of Common Stock
have the right in certain circumstances to require the Company to register their
shares under the Securities Act  for resale to the  public. If such holders,  by
exercising  their demand registration rights, cause  a large number of shares to
be registered and sold in  the public market, such  sales could have an  adverse
effect  on the market price for the  Company's Common Stock. If the Company were
required to  include in  a Company-initiated  registration shares  held by  such
holders  pursuant to  the exercise  of their  piggyback registration  rights and
shares held by the holders of an  additional 83,741 shares of Common Stock  with
piggyback  registration rights,  such sales  may have  an adverse  effect on the
Company's ability  to  raise needed  capital.  The  Company intends  to  file  a
registration  statement  on  Form S-8  on  or  shortly after  the  date  of this
Prospectus registering a total of approximately 1,794,000 shares of Common Stock
subject to  outstanding  stock  options  or  reserved  for  issuance  under  the
Company's  stock option plans. Shares issued after the effective date of the S-8
will be  eligible for  resale by  non-affiliates in  the public  market  without
limitation  and by affiliates subject to the requirements set forth in Rule 144,
except for  the holding  period limitation  of Rule  144. See  "Management--1996
Stock  Option/Stock Issuance Plan,"  "Description of Capital Stock--Registration
Rights  of   Certain   Holders,"  "Shares   Eligible   for  Future   Sale"   and
"Underwriting."
    
 
   
    NO  PRIOR PUBLIC MARKET FOR COMMON STOCK.  Prior to this offering, there has
been no public market for the Common  Stock, and there can be no assurance  that
an  active public market for the Common Stock will develop or be sustained after
the  offering.  The  initial  public  offering  price  will  be  determined   by
negotiations  between the Company  and the representatives  of the Underwriters.
See "Underwriting" for a discussion of the factors considered in determining the
initial public offering price.
    
 
    ANTITAKEOVER CONSIDERATIONS.    The  Company's Sixth  Amended  and  Restated
Certificate of Incorporation (the "Certificate of Incorporation") authorizes the
Board  of  Directors to  issue, without  stockholder  approval, up  to 1,000,000
shares  of  Preferred  Stock  with  voting,  conversion  and  other  rights  and
preferences
 
                                       12
<PAGE>
   
that  could adversely affect the voting power  or other rights of the holders of
Common Stock. The Certificate of Incorporation also provides for staggered terms
for the members  of the Board  of Directors.  In addition, the  Company will  be
subject  to the  provisions of Section  203 of the  Delaware General Corporation
Law, which will  generally prohibit  the Company  from engaging  in a  "business
combination"  with an "interested stockholder" for a period of three years after
the  date  of  the  transaction  in  which  the  person  became  an   interested
stockholder, unless the business combination is approved in a prescribed manner.
The  foregoing and other provisions of  the Certificate of Incorporation and the
Company's By-laws, as amended (the "By-laws") and the application of Section 203
of the  Delaware General  Corporation Law  could have  the effect  of  deterring
certain  takeovers  or  delaying or  preventing  certain changes  in  control or
management of the  Company, including transactions  in which stockholders  might
otherwise  receive a premium  for their shares over  then current market prices.
See "Description  of Capital  Stock--Preferred Stock"  and "--Delaware  Law  and
Certain  Provisions of the  Company's Restated Certificate  of Incorporation and
By-laws."
    
 
    SUBSTANTIAL DILUTION.  Purchasers of  shares of Common Stock offered  hereby
will  experience immediate  and substantial  dilution in  the net  tangible book
value of their  investment from  the initial public  offering price.  Additional
dilution  will  occur upon  exercise of  outstanding  options and  warrants. See
"Dilution."
 
                                       13
<PAGE>
                                USE OF PROCEEDS
 
   
    The net proceeds to  the Company from  the sale of  the 2,200,000 shares  of
Common   Stock  offered  by  the  Company  are  estimated  to  be  approximately
$21,506,000 at an  assumed initial public  offering price of  $11.00 per  share,
after  deducting  the  estimated  underwriting  discounts  and  commissions  and
offering expenses  payable by  the Company.  The Company  will not  receive  any
proceeds from the exercise, if any, of the Underwriters' over-allotment option.
    
 
   
    The Company currently anticipates that approximately $7.0 million of the net
proceeds  will be used to fund  capital expenditures associated with the planned
expansion of  its  Internet network  infrastructure  through the  end  of  1997,
however  there can  be no  assurance that  actual capital  expenditures will not
exceed that amount. The remainder of the net proceeds are anticipated to be used
for working capital requirements, including increased selling and marketing  and
research  and development efforts, for  the repayment of short-term indebtedness
as described below and for general corporate purposes. The Company may also  use
a  portion of the net proceeds to fund acquisitions of complementary businesses,
products  or  technologies,  although  there   are  no  current  agreements   or
negotiations  with  respect to  any  such transaction.  The  Company will  use a
portion of the net proceeds to  repay the outstanding principal amount of,  plus
accrued  interest on, the Company's working capital line of credit. In addition,
a portion of the net  proceeds will be used  to repay the outstanding  principal
amount  of the Company's term loan  facility, together with accrued interest, as
it comes due. As of August 31, 1996, approximately $0.5 million was  outstanding
under  the working  capital line  of credit  and approximately  $0.5 million was
outstanding under the term loan facility. The working capital line of credit and
the term loan facility, which together constitute the Company's credit  facility
(the  "Credit Facility") with Silicon Valley Bank (the "Bank"), bear interest at
the Bank's prime rate plus 0.5% (8.75% at August 31, 1996). The working  capital
line,  which matures in full on April 14, 1997, was utilized for working capital
purposes.  The  term  loan  facility,  which  is  repayable  in  equal   monthly
installments  over  a  three-year period  commencing  on October  14,  1996, was
utilized to  finance  capital  expenditures. See  "Management's  Discussion  and
Analysis of Financial Condition and Results of Operations--Liquidity and Capital
Resources."
    
 
    Pending  use of the net proceeds for the above purposes, the Company intends
to invest  the net  proceeds  in short-term  debt instruments,  certificates  of
deposit or direct or guaranteed obligations of the United States.
 
                                DIVIDEND POLICY
 
   
    The Company to date has not declared or paid dividends on its capital stock.
In  addition, the Company's Credit Facility  with the Bank prohibits the Company
from paying dividends without the Bank's consent. The Company intends to  retain
any  earnings  to fund  future growth  and  the operation  of its  business and,
therefore, does  not anticipate  paying any  cash dividends  in the  foreseeable
future.  The payment of  any future dividends  will be at  the discretion of the
Company's Board of Directors and will be based on the Company's future earnings,
financial condition, capital requirements and other relevant factors.

                                    DILUTION
 
   
    The pro forma net tangible book value of the Company as of June 30, 1996 was
approximately  $3.1 million  or $0.37  per share.  "Pro forma  net tangible book
value per share" is determined by dividing the tangible net worth of the Company
(total tangible assets less total liabilities),  by the number of shares of  pro
forma  Common Stock outstanding. The number of  shares of pro forma Common Stock
outstanding gives effect to the one-for-nine  reverse stock split of the  Common
Stock to be effected prior to the closing of this offering and to the conversion
of  all  outstanding  shares of  all  series  of the  Company's  Preferred Stock
outstanding as of June 30, 1996 into an aggregate of 7,790,489 shares of  Common
Stock  upon the closing of this offering. Without taking into account any of the
changes in such pro  forma net tangible  book value after  June 30, 1996,  other
than  to give  effect to  the sale of  2,200,000 shares  of Common  Stock by the
Company in this offering (at an assumed initial public offering price of  $11.00
per  share,  and  after  deducting  the  estimated  underwriting  discounts  and
commissions and offering  expenses payable by  the Company), the  pro forma  net
tangible  book  value  of  the Company  as  of  June 30,  1996  would  have been
approximately $24.6 million  or $2.37  per share. This  represents an  immediate
increase  in pro forma  net tangible book  value of $2.00  per share to existing
stockholders and immediate  dilution in  pro forma  net tangible  book value  of
$8.63 per share to new investors. The following table illustrates this per share
dilution:

                                 CAPITALIZATION
 
   
    The  following table sets forth the  pro forma capitalization of the Company
as of June 30, 1996, and as adjusted  to give effect to the sale by the  Company
of  2,200,000 shares of Common Stock at an assumed initial public offering price
of $11.00 per share,  after deducting the  estimated underwriting discounts  and
commissions and offering expenses payable by the Company, and the application of

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
   
    The  Company  derives  its  revenues  from the  provision  of  a  variety of
facsimile services largely to small to medium sized businesses and professionals
involved in international commerce. Through the end of 1995, the Company offered
its services exclusively to customers located in the United States. In the first
quarter of 1996, the Company began to focus on the broader worldwide market  for
facsimile  services through the introduction of client software to enable faxing
from the computer desktop using the Internet  as the means to access the  FaxSav
network.  The Company's  network in  the United  States includes interconnection
with the existing  worldwide telephony network,  enabling delivery of  facsimile
transmissions  to  virtually  any  domestic  or  international  destination. The
Company has deployed Internet fax nodes  in Bermuda, France, Germany, Hong  Kong
and  the United Kingdom  and plans to  install additional Internet  nodes in key
international telecommunications  markets to  enable the  Company ultimately  to
route a majority of its customers' traffic through the Internet.
    
 
   
    The Company charges customers monthly for its services based upon the actual
duration (number of minutes) for transmissions originating on facsimile machines
or  individual facsimile transmission  size (number of  pages) for transmissions
originating on  computer desktops.  Although the  Company does  not require  its
customers  to enter into long-term  contractual agreements, once customers begin
to use the  services regularly, they  often continue  to use the  services on  a
recurring  basis. Accordingly, the  Company believes that  its operating results
benefit from  the recurring  monthly  revenue stream  from such  customers.  The
Company  has experienced a loss rate of  customer fax lines of approximately 40%
annually, which management  believes has  been primarily  driven by  competitive
pricing.  Due to  the recent  introduction of  the FAXSAV  PLUS service  and the
FAXSAV FOR INTERNET suite of services,  which provide more favorable pricing  to
its  customers, the Company  anticipates that such loss  rate will decrease over
time, although there can be no assurance that such rate will not remain constant
or increase in the future.
    
 
   
    The Company's  revenue  and  expense  levels  have  continued  to  increase,
particularly  in 1995  and through the  six months  ended June 30,  1996, as the
Company's customer base has expanded and the Company has invested in the design,
development and marketing  of its  newer services, including  FAXSAV EZ-LIST,  a
fax-to-fax  broadcast service, and the FAXSAV FOR INTERNET suite of services. On
an annual basis, cost of  service, general and administrative expenses,  network
operations  and support expenses and sales and marketing expenses decreased as a
percentage of revenues in 1995 in comparison to 1994. In the first six months of
1996, cost of  service further decreased  as a percentage  of revenues from  the
same  period in 1995  but operating expenses  increased in the  1996 period as a
result of the development, promotion and marketing of new services.
    
 
   
    The Company is seeking to form strategic sales and marketing alliances  with
foreign  Internet service providers, telecommunications companies and resellers.
The Company anticipates that these organizations will use their knowledge of the
local market,  language, customs  and  regulations, as  well as  their  existing
distribution,  customer support and billing  infrastructures, to establish, grow
and properly  service an  international  FaxSav customer  base. In  return,  the
Company is offering these organizations either exclusive or non-exclusive rights
to  market the Company's  services in their territories  and offering to provide
such services at a discount to the Company's retail prices. To date the  Company
has formed preliminary strategic alliances with companies in Bermuda, Hong Kong,
Japan,  Korea, Lebanon, the Philippines, Singapore  and Taiwan. In addition, the
Company has  formed  a  preliminary  strategic alliance  with  a  United  States
corporation  regarding  activities  in  Mexico.  The  Company  has  entered into
non-binding letters  of intent  with respect  to these  strategic alliances.  In
addition, the Company is developing a network of commission-based agents to sell
the  FAXSAV FOR  INTERNET suite  of services in  foreign markets.  To date, this
network consists of 31 agents representing the Company in 23 foreign markets.
    
 
   
    A key element  of the Company's  current business strategy  is to offer  its
FAXSAV  PLUS service  at prices  based on the  economics of  delivery through an
Internet backbone. The Company is currently implementing its FAXSAV PLUS service
with  a  two-tiered  pricing  structure.   Pricing  for  delivery  to  the   key
telecommunications  markets currently  targeted for Internet  node deployment is
based on the economics of delivery through
    
 
                                       18
<PAGE>
   
a  planned  Internet  backbone,  even  if  the  Company  has  not  yet  deployed
Internet-capable  facsimile nodes  in such  markets. At  September 1,  1996, the
Company had not  yet deployed  Internet-capable nodes  in 27  of such  currently
targeted markets. Pricing for delivery to other destinations worldwide continues
to  be based on the economics  of delivery through the Company's telephony-based
network, which prices may or  may not be reduced in  the event that the  Company
deploys Internet-capable facsimile nodes in such markets. It is anticipated that
this  pricing strategy,  which the  Company introduced  in the  third quarter of
1996, will generally reduce  the Company's overall gross  profit margin until  a
sufficient  number of telecommunications  markets are serviced  by the Company's
Internet-capable nodes. The Company  currently anticipates that,  by the end  of
1997,   it   will   have   deployed  Internet-capable   nodes   in   enough  key
telecommunications markets  worldwide to  generally  improve its  overall  gross
profit  margin. The Company currently  anticipates that approximately $7 million
of the  net  proceeds  of  this  offering will  be  used  to  fund  the  capital
expenditures  associated with its planned Internet-capable node expansion. There
can be no  assurance that  the Company  will be  able to  deploy the  additional
Internet-capable  nodes on a timely basis, at a commercially reasonable cost, or
at all, or that overall gross margins will improve when anticipated, or at  all.
Any  failure of  the Company  to deploy  the contemplated  Internet-capable node
infrastructure on a  timely basis could  have a material  adverse effect on  the
Company's  business, financial  condition and  results of  operations. See "Risk
Factors --  Dependence on  Network Infrastructure;  No Assurance  of  Successful
Internet-Capable Node Deployment."
    
 
   
    To  date, the Company has financed  its cash requirements for operations and
investments in equipment primarily through  private sales of equity  securities,
bank  borrowings and capital lease financing. The Company has incurred operating
losses since its inception in 1989. Based on the Company's anticipated increases
in expenses for  new product development,  deployment of Internet-capable  nodes
and  sales and marketing programs, the Company  expects to incur a net operating
loss for the year ended December 31, 1996, and it expects to incur losses in the
future.

</TABLE>
 
    SIX MONTHS ENDED JUNE 30, 1995 AND 1996.
 
    REVENUES.  Revenues, which consist primarily of customer usage charges, grew
48.4% to $7.4 million in the six months ended June 30, 1996 from $5.0 million in
the  six  months ended  June 30,  1995 primarily  as a  result of  the continued
expansion of  the  Company's  customer  base.  Commercial  introduction  of  the
Company's  FAXSAV EZ-LIST  broadcast service  and FAXSAV  FOR INTERNET  suite of
services was begun  in the first  quarter of  1996, but the  revenues for  these
services  were  not  significant.  In  total,  revenues  from  international fax
deliveries increased to 86.5% of revenues in the six months ended June 30,  1996
from 82.4% in the same period in 1995.
 
    COST  OF SERVICE.  Cost of service  consists of local access charges, leased
network backbone  circuit costs  and long  distance domestic  and  international
termination  charges.  These  are  primarily  variable  costs  based  on  actual
facsimile volume.  Cost of  service increased  as a  result of  the increase  in
facsimile volume for the period but decreased as a percentage of revenues in the
six  months ended June 30, 1996 to 57.5% from 61.9% in the six months ended June
30, 1995. The Company's costs for international termination charges in the  1996
period were lower as a percentage of revenue as a result of the Company's volume
commitment to its major telephony common carrier.
 
    NETWORK  OPERATIONS  AND  SUPPORT.   Network  operations  and  support costs
consist primarily  of  the  expenses  of operating  and  expanding  the  network
infrastructure,  monitoring network traffic and quality of service and providing
customer support in service installations, fax deliveries and message  reporting
and  billing. Network operations and support  costs increased to $0.9 million in
the six months ended  June 30, 1996  from $0.6 million in  the six months  ended
June  30,  1995 as  a result  of  hiring additional  personnel to  implement the
Internet fax  node  deployment  plan  and to  support  the  Company's  expanding
customer base. These costs increased as a percentage of revenues to 11.7% in the
six months ended June 30, 1996 from 11.3% in the same period in 1995.
 
                                       20
<PAGE>
    RESEARCH  AND  DEVELOPMENT.    Research  and  development  expenses  consist
primarily of  salaries  and  consulting  fees paid  to  software  engineers  and
development  personnel. Research and development  expenses increased by 95.9% in
the six months ended June  30, 1996 in comparison to  the six months ended  June
30,  1995  due to  the continuing  development efforts  for enhancements  to the
Company's Internet desktop-to-fax services both  in client software and  network
enhancements  and  the continuing  development of  the Company's  FAXSAV EZ-LIST
broadcast service.  As a  percentage of  revenues, these  expenses increased  to
10.5%  in the six months ended  June 30, 1996 from 8.0%  in the six months ended
June 30, 1995.
 
    SALES AND  MARKETING.   Sales and  marketing expenses  consist primarily  of
salaries  and commissions for  sales and marketing  staffs, promotional material
preparation and mailing costs, third  party telemarketing charges and agent  and
dealer  commissions. Sales and marketing expenses  increased to $3.0 million for
the six months  ended June 30,  1996 in comparison  to $2.0 million  in the  six
months  ended June 30, 1995. As a percentage of revenues, these costs were 40.6%
in both the 1996 and 1995 periods. During 1996, the Company initiated a  program
of  presenting its FAXSAV FOR  INTERNET suite of services  at trade shows in the
United States and  in foreign countries  where it plans  to deploy Internet  fax
nodes.  The  Company also  initiated an  advertising  and promotion  campaign to
promote its new services and expanded its sales and marketing staff.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist  of
expenses  associated with the Company's management, accounting, finance, billing
and administrative functions. General  and administrative expenses increased  to
$1.4  million and 18.5% of  revenues in the six months  ended June 30, 1996 from
$0.8 million and 16.8% of  revenues in the six months  ended June 30, 1995.  The
increase  in total general and administrative expenses and the increase of these
expenses as a percentage of revenues result from personnel increases to  support
the increased customer base, expenses incurred for management information system
improvements and management recruiting fees.
 
    DEPRECIATION  AND AMORTIZATION.   Depreciation and  amortization amounted to
$0.6 million in the six months ended June 30, 1996 in comparison to $0.3 million
in the six months ended June 30, 1995, primarily reflecting depreciation of  the
Company's  increased  investment  in  FAXSAV  CONNECTORS  installed  at customer
premises to allow access to the FaxSav network.
 
    OTHER.  Other operating income of $0.2 million for the six months ended June
30, 1995 represents service fees received under a Service Agreement with Telstra
which offset various operating expenses  incurred in support of the  development
of Telstra's "WorldFax" service in the U.S. The Agreement expired in 1995.
 
    PROVISION  FOR INCOME TAXES.  The Company had losses for income tax purposes
for the six  months ended  June 30,  1995 and  1996. Accordingly,  there was  no
provision  or credit for income taxes for those periods. Any income tax benefits
at the Company's expected effective tax rate for these losses has been offset by
an expected increase in valuation allowance for deferred tax assets.
 
    YEARS ENDED DECEMBER 31, 1993, 1994 AND 1995
 
    REVENUES.  Revenues grew 33.7% from $2.6 million in 1993 to $3.4 million  in
1994  and 237.8% to $11.6 million in 1995  primarily as a result of increases in
the number of the Company's customers. This growth in the customer base resulted
from the  introduction in  the second  quarter  of 1994  of the  Company's  core
fax-to-fax  service, FAXSAV; the initiation  in the second quarter  of 1994 of a
direct  mail   and  telemarketing   program   conducted  through   third   party
telemarketing firms, which was expanded through the end of 1994 and in 1995; the
development  in the third quarter of 1994 of a network of independent agents and
dealers selling FaxSav services in addition to other products and services;  and
an  increase  in the  number  of the  Company's  sales and  marketing personnel,
particularly in 1995.
 
    COST OF SERVICE.  Cost of service  increased in 1994 and 1995 in  comparison
to  the  previous  years  because  of the  increased  customer  base  but,  as a
percentage of revenues, cost of service decreased from 71.9% of revenues in 1993
to 66.6% in 1994  and to 60.3%  in 1995. Cost savings  from volume discounts  on
long  distance termination charges and more efficient network operations through
least cost  routing were  the significant  factors in  reducing this  cost as  a
percentage of revenues.
 
                                       21
<PAGE>
    NETWORK  OPERATIONS AND SUPPORT.  Network  operations and support costs were
$0.7 million and $0.9 million in 1993 and 1994 and increased to $1.2 million  in
1995  as  a  result of  hiring  additional  personnel to  support  the Company's
expanding customer base. Due  to increased revenues these  costs decreased as  a
percentage of revenues from 28.8% in 1993 to 24.7% in 1994 and decreased further
to 10.2% in 1995.
 
    RESEARCH AND DEVELOPMENT.  Research and development costs were $0.6 million,
$0.6  million,  and  $0.8 million  in  1993,  1994 and  1995,  respectively. The
increase in 1995 was due to (i) the development efforts for the Company's FAXSAV
FOR INTERNET suite of  services client software  and network enhancements;  (ii)
the  development of  the Company's FAXSAV  EZ-LIST broadcast  service; and (iii)
software enhancements  to  the  Company's FAXSAV  CONNECTOR.  Due  to  increased
revenues,  research and development  expenses have decreased  as a percentage of
revenues from 24.3% in 1993 to 17.8% in 1994 and 7.2% in 1995.
 
    SALES AND MARKETING.   These expenses increased in  1994 to $2.3 million  in
comparison  to $1.6 million in 1993 in connection with the rollout in the United
States of the Company's core business  service, FAXSAV, beginning in the  second
quarter of 1994. In 1995, sales and marketing expenses increased to $4.2 million
but  decreased as a  percentage of revenues to  36.4% from 67.8%  in 1994 due to
increased revenues.
 
    GENERAL AND ADMINISTRATIVE.   General and administrative expenses  increased
to  $2.2 million in 1995 from $1.0 million in 1994 and 1993, but on a percentage
of revenue basis these costs decreased to  19.2% in 1995 from 29.9% in 1994  and
36.9%  in 1993 due to increased revenues. The increase in 1995 was due primarily
to the  hiring  of  additional  personnel to  support  the  Company's  expanding
customer base.
 
    DEPRECIATION  AND AMORTIZATION.   Depreciation and  amortization amounted to
$0.1 million in 1993, $0.2  million in 1994 and $0.7  million in 1995. The  most
significant  item  causing these  increases  was depreciation  on  the Company's
increased investment  in  FAXSAV  CONNECTORS which  are  installed  at  customer
premises to access the FaxSav network.
 
    OTHER.   Other operating income of $0.3  million in 1994 and $0.4 million in
1995, represents service fees  received under a  Service Agreement with  Telstra
which expired in 1995.
 
    PROVISION  FOR INCOME TAXES.  The Company had losses for income tax purposes
for the years ended December 31, 1993, 1994 and 1995. Accordingly, there was  no
provision  for income  taxes in  those years.  Any income  tax benefits  for the
Company's operating  losses have  been  offset by  an  increase in  a  valuation
allowance for deferred tax assets.

    The  Company may  in the  future experience  significant quarter  to quarter
fluctuations in  its results  of  operations. Such  fluctuations may  result  in
volatility  in the  price of  the Company's  Common Stock.  Quarterly results of
operations may fluctuate as a result  of a variety of factors, including  demand
for  the  Company's  services,  the introduction  of  new  services  and service
enhancements by the Company or its
 
                                       23
<PAGE>
competitors, market  acceptance of  new services,  the mix  of revenues  between
Internet-based  versus  telephony-based  delivery,  the  timing  of  significant
marketing programs, the number and timing of the hiring of additional personnel,
competitive conditions  in the  industry and  general economic  conditions.  The
Company's  revenues  are  difficult  to  forecast.  Shortfalls  in  revenues may
adversely and  disproportionately affect  the  Company's results  of  operations
because  a high  percentage of the  Company's operating  expenses are relatively
fixed, and  planned  expenditures, such  as  the anticipated  expansion  of  the
Company's  Internet infrastructure, are  based primarily on  sales forecasts. In
addition, the stock market in general  has experienced extreme price and  volume
fluctuations,  as evidenced by the fluctuations in the Nasdaq National Market in
July 1996, which have affected the market price of securities of many  companies
in  the telecommunications and technology  industries. These market fluctuations
may  adversely  affect  the  market   price  of  the  Company's  Common   Stock.
Accordingly,  the Company believes that period  to period comparisons of results
of operations are not necessarily meaningful and should not be relied upon as an
indication of future results of operations.  There can be no assurance that  the
Company  will be profitable in any future quarter. Due to the foregoing factors,
it is likely that in one or more future quarters the Company's operating results
will be below the expectations of public market analysts and investors. Such  an
event  could have a material adverse effect on the price of the Company's Common
Stock.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
    The  Company  has  financed  its   cash  requirements  for  operations   and
investments  in equipment primarily through  private sales of equity securities,
bank borrowings and capital lease financing. Cash flows from the sales of equity
securities amounted to $7.9 million in the  six months ended June 30, 1996,  net
of  issuance costs, $2.2 million of which  were used to repurchase shares of the
Company's Series  D Preferred  Stock  from a  major  stockholder pursuant  to  a
pre-existing  option. Cash flows from the sales of equity securities amounted to
$4.2 million and $4.1  million in 1995 and  1994, respectively, net of  issuance
costs. Cash flows associated with bank borrowings amounted to a net repayment of
$0.3  million in the six  months ended June 30, 1996  and net borrowings of $1.0
million in  1995.  Cash  flows  from  financing  activities  in  1993  primarily
consisted  of  proceeds from  the issuance  of notes  payable amounting  to $0.3
million.
    
 
   
    As a result of operating losses, cash used in operating activities  amounted
to  $2.2 million in  the six months ended  June 30, 1996  and $3.5 million, $3.2
million and $2.8  million in  1995, 1994 and  1993, respectively.  Cash used  in
investing  activities, largely consisting of the purchase of equipment, amounted
to $0.9 million in  the six months  ended June 30, 1996  and $1.3 million,  $0.7
million  and $0.2  million in  1995, 1994  and 1993,  respectively. Beginning in
1994, this equipment primarily consisted  of FAXSAV CONNECTORS purchased by  the
Company  for installation at  customer locations. Not  all FAXSAV CONNECTORS are
returned to  the  Company when  service  is terminated,  therefore  some  FAXSAV
CONNECTORS  at former  or inactive  customers are  considered unrecoverable. The
Company provides for the estimated book value of such unrecoverable equipment by
a charge to operations when the determination is made. In addition, network  and
computer equipment, amounting to $0.6 million and $0.1 million in 1995 and 1994,
respectively, was financed under capital leases.
    
 
   
    The  Company's principal sources of liquidity at June 30, 1996 included cash
and cash equivalents of $2.8 million, available financing of approximately  $0.7
million under the Credit Facility with the Bank and available lease financing of
$0.4  million. In April 1996, the Company amended the Credit Facility to consist
of a working capital  credit line of  $1.0 million and a  term facility of  $0.8
million  to finance  capital expenditures. The  Credit Facility is  limited to a
borrowing  base  determined   by  the  Company's   eligible  receivables,   with
approximately  $1.3 million  available for borrowing  thereunder as  of June 30,
1996. The term  loan facility becomes  due and payable  in monthly  installments
over  a  three-year period,  commencing  on October  14,  1996, and  the working
capital credit line  becomes due  and payable  in full  on April  14, 1997.  The
Credit  Facility bears interest at the Bank's  prime rate plus 0.5%. At June 30,
1996, the Company was in default of certain financial covenants contained in the
Credit Facility. On July  31, 1996, the Bank  waived these defaults and  amended
the  applicable  covenants  in  the  Company's  favor,  but  limited  the  total
outstanding indebtedness under  the Credit  Facility to $1.0  million until  the
Company  raises additional equity capital. In  addition, the Credit Facility, as
amended, contains a covenant that this  offering must occur or the Company  must
raise an additional $3 million in equity on or before October 15, 1996.
    
 
                                       24

    The   Company  anticipates  that  its  capital  expenditures  will  increase
significantly for investment in network facilities and to a lesser extent FAXSAV
CONNECTORS. As of  June 30, 1996,  the Company had  equipment lease  commitments
totaling  $0.7 million. Through  October 1996, the Company  is obligated to LDDS
WorldCom  for  a  minimum  monthly   usage  commitment  of  $0.25  million   for
international long distance service, and through April 1999, is obligated to MCI
for  a minimum monthly usage commitment  for domestic interstate and intra-state
service ranging from an average  of $0.1 million per  month for the first  eight
months to $0.2 million per month thereafter.
 
   
    Through  December  31,  1995,  the Company,  for  income  tax  purposes, has
generated NOL carryforwards of approximately $16.1 million which will expire  in
the  years 2005  through 2010.  Use of  the NOL  carryforwards to  offset future
taxable income of the Company, if any, will be subject to limitation due to  the
ownership change provisions of Section 382 of the Internal Revenue Code of 1986,
as  amended. Additional sales  of the Company's equity  securities may result in
further limitations on the  use of NOL carryforwards  against taxable income  in
future years. Based upon the Company's history of operating losses and presently
known  factors, management has determined  that it is more  likely than not that
the Company will be  unable to generate sufficient  taxable income prior to  the
expiration  of these NOL carryforwards and  has accordingly reduced its deferred
tax assets to zero with a full valuation allowance.
    
 
    The Company currently  believes that  the net proceeds  from this  offering,
together with its current cash and cash equivalents and available bank and lease
financing  facilities, will be sufficient to meet its anticipated cash needs for
working capital and capital expenditure requirements through at least the end of
1997. Thereafter, if the Company does not begin to generate positive cash  flows
from  operations  in  amounts  that  are  sufficient  to  satisfy  the Company's
liquidity requirements, it will be necessary for the Company to raise additional
funds through bank  facilities, debt  or equity  offerings or  other sources  of
capital.  Additional  funding  may not  be  available  when needed  or  on terms
acceptable to the  Company, which could  have a material  adverse effect on  the
Company's business, financial condition and results of operations.

                                    BUSINESS
GENERAL
    FaxSav  designs,  develops  and markets  a  variety  of business-to-business
facsimile transmission services, including real-time fax-to-fax, desktop-to-fax,
enhanced fax and broadcast fax  services. The Company has developed  proprietary
software  which enables its customers to specify on a call-by-call basis whether
a facsimile transmission will be delivered through FaxSav's real-time,  "virtual
real-time"  or broadcast services. This software, coupled with FaxSav's fax-only
network of two interconnected switching nodes in the United States and a growing
base of Internet-capable facsimile  nodes overseas, automatically delivers  each
outgoing  transmission through the  route that provides the  lowest cost and the
highest transmission  quality available  on the  FaxSav network.  Pre-negotiated
volume-based arrangements with several telephony common carriers (including LDDS
WorldCom,  MCI  and Telstra)  and the  cost  savings available  for transmission
through the  Internet enable  FaxSav to  transmit its  customers' documents  and
images  to  fax machines  worldwide at  rates that  are significantly  below the
international rates  charged  by  long distance  voice  carriers.  While  FaxSav
generates  cost savings primarily for United States customers transmitting faxes
to international  destinations, many  FaxSav customers  also use  the  Company's
services for domestic transmissions where ease of use, rather than cost savings,
is the principal motivation.
 
   
    The   Company  is   deploying  Internet-capable   facsimile  nodes   in  key
international telecommunications markets ultimately to enable it to migrate  the
majority  of its  customers' traffic off  of its telephony-based  network and to
route it  over the  Internet. The  Company believes  that this  global  Internet
backbone,  which  is designed  to  seamlessly integrate  with  FaxSav's existing
telephony-based network, will enable the Company to bypass long distance  common
carriers  for transmissions originating and  terminating in countries where such
nodes have been deployed, thereby further reducing its customers'  international
transmission  costs. FaxSav believes that the combination of its telephony-based
network and its  growing Internet-based network  will enable it  to emerge as  a
leading  supplier of comprehensive, low-cost global faxing services. The Company
has added Internet capability  to its switching nodes  in the United States  and
has  deployed one  Internet-capable facsimile node  in each  of Bermuda, France,
Germany, Hong  Kong  and the  United  Kingdom. FaxSav  anticipates  deploying  a
sufficient   number  of  additional  nodes  in  key  telecommunications  markets
worldwide by the end of 1997 to enable it to route a majority of its  customers'
traffic through the Internet.
    
 
   
    The Company's customer base, revenues and facsimile transmission volume have
grown  substantially  in  recent  periods. The  Company's  customer  base, which
primarily consists of United States businesses  in a broad range of  industries,
has   grown  from  approximately  3,300  customers   at  December  31,  1994  to
approximately 7,200 customers at June 30, 1996, plus over 1,000 registered users
of the Company's  desktop-to-fax services. The  following chart illustrates  the
Company's  revenue growth  from the  quarter ended June  30, 1994,  in which the
FAXSAV service was first  introduced, through the quarter  ended June 30,  1996,
separately identifying the domestic and international destination components:

The  Company's  revenues have  increased from  $3.4 million  for the  year ended
December 31, 1994 to $11.6 million for the year ended December 31, 1995 and from
$5.0 million for the six months ended June 30, 1995 to $7.4 million for the  six
months  ended  June 30,  1996. In  addition, the  minutes of  facsimile messages
transmitted by FaxSav increased from 6.1 million for the year ended December 31,
1994 to 20.4 million for the year ended December 31, 1995, and from 9.0  million
for  the six months ended June 30, 1995 to 13.8 million for the six months ended
June 30, 1996.
 
INDUSTRY BACKGROUND
 
    THE MARKET FOR FACSIMILE SERVICES
 
   
    Technological advances  over the  past decade  have improved  the speed  and
quality  of  facsimile transmissions  and reduced  the cost  of fax  machines to
consumers, resulting in a large and  increasing worldwide installed base of  fax
machines.  According  to  industry  sources, worldwide  sales  of  new facsimile
machines reached approximately 11 million in 1994 and approximately 12.5 million
in 1995,  and  the 1994  worldwide  installed  base of  facsimile  machines  was
approximately  30.7  million.  In  addition, there  recently  has  been  a rapid
increase  in  the  installed  base   of  fax-capable  personal  computers.   The
proliferation of fax machines and fax capable computers, and improvements in the
transmission  quality  of domestic  and  international telephone  networks, have
resulted in  facsimile  transmission  being the  preferred  means  of  immediate
business-to-business document delivery.
    
 
    TRADITIONAL INTERNATIONAL FACSIMILE TRANSMISSION
 
    A  facsimile message typically  is transmitted by means  of a telephone call
from one  fax  machine to  another  over the  voice  telephony network.  Once  a
connection has been established between the two machines, the scanned image from
the originating fax machine is electronically transmitted to the destination fax
machine.  Facsimile transmissions historically have  been, and substantially all
of such  transmissions continue  to be,  implemented on  a real-time  continuous
connection basis using the voice telephony network as a transmission medium.
 
   
    An  international facsimile transmission from the United States typically is
routed as  follows: (i)  the sending  fax machine  accesses the  local  exchange
carrier  (an "LEC"), which then  routes the fax to  the customer's long distance
carrier; (ii)  the long  distance carrier  then  routes the  fax via  its  voice
telephony network to the telephone company of the destination country; and (iii)
the foreign telephone company then routes the fax to a local telephone number to
which  the  destination  fax machine  is  attached.  In this  example,  the long
distance company will bill the customer to cover the LEC access fee, the fee for
use of its voice telephony  network and the fee  for the connection between  the
long  distance  carrier's  network  and  the  foreign  telephone  company, which
includes the fee for delivery to the destination fax machine. Based on FCC data,
the  Company  estimates  that  the  average   retail  price  for  a  minute   of
international  transmission from the  United States to  a destination outside of
North America was approximately  $1.20 in 1994, with  a majority of this  amount
being  attributable  to the  average inter-country  connection fee.  The Company
believes, based on  the experience  of its  management team,  that such  average
retail price has not significantly decreased.
    
 
    DOCUMENT DELIVERY OVER THE INTERNET
 
    Substantially  all inter-country facsimile  traffic worldwide is transmitted
through voice telephony  networks at  rates which  are largely  dictated by  the
inter-country   connection   fees.   Unlike  traditional   public   and  private
telecommunications networks, which are individually  managed, the Internet is  a
cooperative  interconnection  of many  such  public and  private  networks which
enables  businesses,   educational   institutions,   government   agencies   and
individuals  to  transmit data  internationally without  incurring inter-country
voice telephony connection fees.
 
    Although the Internet has been  used for a number of  years as a medium  for
the international delivery of documents from computer to computer, substantially
all facsimile traffic worldwide continues to originate
 
                                       27
<PAGE>
and  terminate on fax  machines. The ability to  effectively capture the savings
enabled by  Internet document  delivery in  the international  facsimile  market
therefore  requires  the  deployment,  on  a  global  basis,  of  a  network  of
Internet-capable facsimile nodes to bridge the gap between the Internet and  the
fax machine.
 
THE FAXSAV SOLUTION
 
   
    FaxSav  is deploying an international  network of Internet-capable facsimile
nodes designed to provide a reliable means to deliver facsimile transmissions to
fax machines  worldwide  at substantially  reduced  costs. This  planned  global
Internet  backbone,  which is  designed  to seamlessly  integrate  with FaxSav's
existing telephony-based network,  will enable the  Company to bypass  expensive
inter-country  connection fees for transmissions  originating and terminating in
countries where such nodes  have been deployed. The  Company has added  Internet
capability  to its  switching nodes  in the United  States and  has deployed one
Internet-capable facsimile node in each  of Bermuda, France, Germany, Hong  Kong
and  the United  Kingdom. FaxSav  anticipates deploying  a sufficient  number of
additional nodes in key telecommunications markets worldwide by the end of  1997
to enable it to route a majority of its customers' traffic through the Internet.
    
 
    FaxSav,  through its integrated  Internet and telephony  network, provides a
comprehensive range of  services for  the global transmission  of documents  and
images, including real-time fax-to-fax, enhanced fax and broadcast fax services.
In  addition,  to position  itself in  the  emerging desktop-to-fax  market, the
Company recently introduced several  proprietary software products which  enable
the  transmission  of  documents or  images  created  in any  Windows  or e-mail
application to be  routed directly from  an Internet-connected computer  desktop
through the FaxSav network to fax machines worldwide.
 
    The  FaxSav  solution  provides substantial  ease  of use  to  the customer.
Customers may begin  transmitting faxes at  substantially reduced costs  without
any  upfront investment  or complex system  installation. FaxSav  is quickly and
easily installed by the  customer and does not  require any changes in  customer
business practices. Customers connect to the FaxSav network by simply installing
a  FAXSAV CONNECTOR,  a small proprietary  device that easily  plugs between the
customer's fax  machine and  the wall  jack, or  by simply  installing  FaxSav's
proprietary   desktop  software  on  an  Internet-connected  personal  computer.
FaxSav's  proprietary  routing  algorithms   then  automatically  deliver   each
facsimile  transmission, through  either FaxSav's telephony  network or Internet
backbone in  order to  optimize the  lowest cost  and the  highest  transmission
quality  available on the  FaxSav network. Additionally,  the FaxSav solution is
both modular and  scalable to meet  customer business  needs in that  it can  be
easily  deployed across  multiple fax machines  or personal  computers within an
organization on an unlimited basis.
 
THE FAXSAV STRATEGY
 
    FaxSav's objective is to be the leading supplier of low-cost, high  quality,
reliable business-to-business global faxing services utilizing the Internet as a
key  transmission medium. FaxSav intends to achieve this position by focusing on
the following key elements:
 
   
        DEPLOY GLOBAL INTERNET INFRASTRUCTURE.  FaxSav recently began to  deploy
    a  network of Internet-capable facsimile nodes  in order to capture the cost
    savings enabled by the  Internet for international facsimile  transmissions.
    The  Company intends  to rapidly deploy  this network  infrastructure in key
    telecommunications markets  worldwide  to  capture these  cost  savings  for
    facsimile  traffic both to and from  such markets. FaxSav has added Internet
    capability to its switching nodes in the United States and has deployed  one
    Internet-capable  facsimile node in  each of Bermuda,  France, Germany, Hong
    Kong and the United Kingdom,  and anticipates deploying a sufficient  number
    of  additional nodes in key telecommunications  markets worldwide by the end
    of 1997 to enable it to route  a majority of its customers' traffic  through
    the Internet.
    
 
        ESTABLISH  PRICE LEADERSHIP  POSITION.   FaxSav intends  to increase its
    customer base by offering  fax delivery services both  in the United  States
    and  overseas  at  substantial  savings  to  traditional  telephony pricing.
    Beginning in the third quarter of 1996, the Company introduced FAXSAV  PLUS,
    a  new "virtual  real-time" service with  pricing based on  the economics of
    delivery through its planned Internet backbone to markets where the  Company
    has  not yet deployed Internet-capable facsimile nodes. Pricing for delivery
    to other  destinations worldwide  are  based on  the economics  of  delivery
    through the Company's
 
                                       28
<PAGE>
    telephony-based network, which prices may or may not be reduced in the event
    that  the Company deploys Internet-capable  facsimile nodes in such markets.
    See  "--Services--FAXSAV  PLUS."  Although   this  pricing  structure   will
    generally   reduce  the  Company's  overall  gross  profit  margin  until  a
    sufficient number  of  Internet-capable  nodes  are  deployed,  the  Company
    anticipates  that  this  strategy  will  enable  it  to  rapidly  expand its
    worldwide market presence.
 
        RAPIDLY EXPAND WORLDWIDE CUSTOMER BASE.  The Company intends to  rapidly
    expand  its  worldwide  customer  base by  leveraging  its  price leadership
    strategy both domestically and internationally.
 
       - DOMESTICALLY.  FaxSav will intensify its sales and marketing efforts in
       the United  States, including  increased  direct mail  and  telemarketing
       activities  and hiring  additional personnel  in its  direct sales group.
       FaxSav  will  continually  monitor  the  market  response  to  its  price
       leadership   strategy  and  refine  its   sales  and  marketing  programs
       accordingly.
 
   
       - INTERNATIONALLY.    The  Company  intends to  establish  and  build  an
       international  customer base by developing  a network of commission-based
       agents to  sell the  FAXSAV FOR  INTERNET suite  of services  in  foreign
       markets  and  by forming  strategic  sales and  marketing  alliances with
       foreign Internet  service  providers,  telecommunications  companies  and
       resellers.  The  Company anticipates  that  these organizations  will use
       their knowledge of the local  market, language, customs and  regulations,
       as  well  as their  existing distribution,  customer support  and billing
       infrastructures, to establish, grow and properly service an international
       FaxSav customer base.
    
 
        MAINTAIN TECHNOLOGY LEADERSHIP.   The Company has developed  significant
    technological  expertise in  all key  aspects of  the facsimile transmission
    business,  including  global  network   design,  routing  and   transmission
    completion  algorithms,  database  programming  and  desktop  software.  The
    Company intends to maintain  its position as a  technological leader in  the
    facsimile  transmission market.  The Company continues  to place significant
    emphasis on the ongoing development of advanced features for its FAXSAV  FOR
    INTERNET suite of services, including the development of client software for
    faxing  from the desktop.  The Company's development  efforts are focused on
    new services and  applications which are  intended to provide  easy to  use,
    cost-efficient  and  reliable  business-to-business  facsimile  transmission
    services on a worldwide basis.
 
THE FAXSAV NETWORK
 
    OVERVIEW
 
   
    TRADITIONAL INTERNATIONAL FACSIMILE TRANSMISSION.  Traditional international
facsimile transmission (see Figure  1) begins when  the originating fax  machine
places a call over the local telephone network. Because the number dialed has an
international  prefix, the Local  Exchange Carrier ("LEC")  switches the call to
the sender's long  distance carrier (typically  AT&T, MCI or  Sprint). The  long
distance  carrier ("LDC") delivers  the call to  the corresponding long distance
company (the "PTT") in the country  of destination, which in turn completes  the
call  by  providing a  connection  through the  local  telephone network  to the
receiving fax  machine. Thus  a  real-time connection  is established  over  the
traditional  telephony networks,  and the originating  fax machine  sends a data
stream, comprising a scanned image, to the receiving fax machine.

<PAGE>
    FACSIMILE TRANSMISSION VIA FAXSAV'S NETWORK.   FaxSav's services, which  are
targeted  at  businesses and  professionals  engaged in  international facsimile
messaging, are designed to reduce the  cost of sending international faxes,  and
to  make the process of  sending such faxes easier  and less time-consuming. The
FaxSav network  offers  its customers  the  benefits of  increased  savings  and
convenience  by  bypassing parts  or all  of  the traditional  network described
above. For example, as  shown in Figure 2,  an international fax-to-fax  message
delivered  through FaxSav's  Internet-based network  utilizes the  Internet as a
delivery medium,  bypassing  the long  distance  carriers and  thereby  avoiding
expensive  inter-country  connection fees.  In  addition, a  customer  using the
FAXSAV FOR INTERNET suite  of services accesses the  FaxSav network through  its
Internet  service provider  (an "ISP") rather  than through  the local telephone
network; the Company's  proprietary software  then either routes  the call  over
FaxSav's  telephony  network  or bypasses  the  long distance  carriers  and the
associated inter-country connection  fees by routing  the call through  FaxSav's
Internet-based network.

    THE FAXSAV NETWORK
 
    The  FaxSav  network  is designed  to  minimize  the cost  of  sending faxes
internationally by selecting the  optimal route and  carrier for each  facsimile
transmission.  Currently FaxSav provides its customers with the ability to reach
fax machines worldwide via its telephony-based network. FaxSav's telephony-based
services  are  competitively  priced  and,   on  faxes  to  most   international
destinations,  FaxSav customers are  expected to realize  substantial savings as
compared to the rates charged by traditional long distance carriers.
 
    In  addition  to  its  telephony-based  network,  FaxSav  is  deploying   an
Internet-based  network which is intended  to connect the key telecommunications
markets worldwide (see Figure 3). FaxSav expects this Internet-based network  to
complement  its  telephony-based  network  and  provide  the  Company  with  the
opportunity to further lower  the retail price  of its customers'  international
facsimile  transmissions while increasing  its market share  and, over time, its
gross margin. As FaxSav continues to deploy its Internet nodes  internationally,
it  will be able to  route an increasing portion  of its customers' traffic over
the  Internet,  and  by  the  end  of  1997  the  Company  expects  to  use  its
Internet-based network to deliver a majority of such traffic.

- ------------
* There  can be no assurance that the  indicated Internet nodes will be deployed
  by the Company on a timely basis, or at all. See "Risk Factors--Dependence  on
  Network  Infrastructure;  No  Assurance  of  Successful  Internet-Capable Node
  Deployment."
 
    FaxSav believes that the combination of its telephony-based network and  its
growing  Internet-based  network  is  critical  to  achieving  its  objective of
emerging as  the  leading  provider  of  comprehensive  low-cost  global  faxing
solutions.  Therefore FaxSav intends  to maintain both  a telephony-based and an
Internet-based network,  and  expects to  eventually  route a  majority  of  its
customers'  traffic through the Internet. The following example, illustrates the
functioning of the planned two-tiered FaxSav network:
 
    - A fax  originating in  New York  would access  the FaxSav  network  either
      through  the local telephone  company (if the customer  uses a fax machine
      with a  FAXSAV  CONNECTOR) or  the  local ISP  (if  the customer  uses  an
      Internet-enabled   personal   computer   with   FAXLAUNCHER,   FAXSCAN  or
      FAXMAILER).
 
    - If the  customer  has  pre-selected FaxSav's  real-time  delivery  service
      option  for faxes to the indicated destination (for example, a fax machine
      in Germany),  FaxSav's  switching node  in  New York  would  automatically
      deliver  the fax through  the most economical  route available in FaxSav's
      telephony-based network.
 
    - If the  customer  has pre-selected  one  of FaxSav's  "virtual  real-time"
      delivery  service  options for  faxes  to the  indicated  destination (for
      example, a fax  machine in  Hong Kong where  an Internet  node is  already
      operational),  FaxSav's  switching node  in  New York  would automatically
      deliver the fax through the Internet  as the least-cost route to  transmit
      the  message.  From  FaxSav's Hong  Kong  Internet node,  delivery  to the
      ultimate destination would be achieved through the local PTT.
 
    - If the  customer  has pre-selected  one  of FaxSav's  "virtual  real-time"
      delivery  service options  for faxes to  an indicated  destination where a
      FaxSav Internet node has not yet been deployed (for example, a fax machine
      in Tokyo), FaxSav's switching node in New York would automatically deliver
      the fax through the most economical route available in FaxSav's two-tiered
      network. This route may be through the Internet to the Company's  Internet
      node in Hong Kong and from there through a PTT to Tokyo or, alternatively,
      from  FaxSav's  switching  node  in New  York  directly  through  the most
      economical route available  in FaxSav's telephony-based  network. Once  an
      Internet  node is  deployed in Japan,  the Company's  switching node would
      automatically deliver  the  fax through  the  Internet as  the  least-cost
      route.

    NETWORK INFRASTRUCTURE
 
   
    At the core of the FaxSav network are two main switching nodes, installed in
New York and Washington, D.C. These switching nodes utilize FaxSav's proprietary
messaging software to provide the full range of the Company's service offerings,
including  real-time  and  "virtual  real-time"  fax  delivery,  least  cost fax
routing, e-mail to fax conversion, Internet access, broadcast delivery, customer
registration and  customer  query  capabilities.  Each  switching  node  employs
switch-to-host  architecture and fully  redundant hardware and  software, and is
interconnected to the  other through a  private intranet utilizing  T1 links.  A
backup connection is also provided through separate T1 links to the Internet via
firewalls.  Both  switching  nodes are  installed  in secure  locations  and are
supported by uninterruptible power supplies  with emergency power generators  as
further  backup. The main switching nodes  are connected through the Internet to
three separate  Internet  facsimile  nodes overseas,  extending  access  to  the
Company's  service in the  markets where such nodes  are located. Internet nodes
provide "virtual real-time" fax  delivery, least-cost fax  routing via the  best
node,  e-mail to fax conversion and  broadcast delivery capabilities. FaxSav has
designed a network-wide redundancy into its  nodes, such that if any  particular
node  fails  for any  reason to  complete a  transmission, an  alternative route
through the FaxSav network will automatically  be selected. In addition, in  the
event  of  an Internet  failure, the  Internet nodes  have a  spanning (multiple
simultaneous calling) dial backup capability  to connect via telephony lines  to
the  nearest node.  This node-based and  network wide redundancy  is designed to
allow FaxSav to reliably provide service to its customers without  interruption.
Additionally,  RSA encryption is  provided in each Internet  node such that each
file delivered through FaxSav's Internet nodes is encrypted, addressing security
concerns of its  customers. In  a limited number  of instances  the Company  has
experienced  a degradation in service to  its customers in confined geographical
areas caused by network problems of its telecommunications suppliers. In each of
these instances, service to the majority  of its customers was not degraded  due
to  the  redundancy of  the  FaxSav network  equipment  and its  diverse routing
capabilities. The Company  has not  experienced any  significant damage,  system
failure  or data loss, nor  has it experienced a  breach of its security systems
resulting in liability to its customers. The Company does not maintain insurance
against these types of potential losses.  All nodes are designed for  unattended
operation,  provide a full range of system monitoring and control capability and
can be upgraded and maintained remotely.
    
 
SERVICES
 
    FAXSAV
 
    FAXSAV, the core fax-to-fax service provided by the Company, is a  real-time
fax transmission service that is delivered through the Company's telephony-based
network. The FAXSAV service is accessed by customers through the installation of
a  FAXSAV CONNECTOR, a small proprietary device which is plugged between the fax
machine and  the telephone  jack. The  FAXSAV CONNECTOR,  which is  programmable
directly  from  FaxSav headquarters  based  on the  customer's  specified needs,
automatically identifies each outgoing call which the customer has  pre-selected
for  delivery by  the Company  and routes  the call  to the  FaxSav network. The
FAXSAV CONNECTOR is provided by FaxSav free of charge with no installation  cost
to  the  customer.  The  Company  believes that,  depending  on  the  volume and
destinations of the customer's traffic, the FAXSAV service provides  significant
savings to customers on fax usage costs in comparison to the international rates
charged  by the major long distance carriers.  FAXSAV customers are charged on a
per-minute basis for the transmission time  to the destination fax machine,  and
are  billed monthly. The  Company also offers customized  pricing plans based on
the customer's volume of traffic to individual countries.
 
    FAXSAV ASSURED
 
    FAXSAV ASSURED is a "virtual  real-time" enhanced delivery option  available
to  all FAXSAV customers through the FAXSAV  CONNECTOR which may be selected for
all of the customer's traffic or on a call by call basis. FAXSAV ASSURED  shifts
the  responsibility for  repetitive completion  attempts to  the FaxSav network,
thereby reducing indirect costs and  increasing the reliability, timeliness  and
predictability  of difficult  facsimile deliveries. The  standard FAXSAV ASSURED
service  immediately   begins   to   attempt  delivery,   and   makes   multiple
 
                                       32
<PAGE>
attempts  for  a  period of  one  hour. If  the  fax has  not  been successfully
completed within that time,  the customer is sent  a "Non-Delivery" notice.  The
Company also offers customized FAXSAV ASSURED services to meet customer-specific
delivery schedules.
 
    FAXSAV EZ-LIST
 
    FAXSAV EZ-LIST is an easy to use fax-to-fax broadcast service which utilizes
the  capabilities of  the FAXSAV  CONNECTOR to capture  the fax  message and the
customer's list identification number in  a single transmission. FAXSAV  EZ-LIST
enables  customers  to  send the  same  fax  message to  multiple  recipients by
transmitting a  single fax  message  to the  FaxSav  network and  identifying  a
specific  list  of fax  addresses previously  stored  in the  Company's customer
database. FAXSAV EZ-LIST  customers are charged  on a per-minute  basis for  the
transmission  time to each destination fax  machine, and are billed monthly. The
Company also offers customized pricing plans  based on the customer's volume  of
traffic to individual countries.
 
    FAXSAV PLUS
 
   
    In  the third  quarter of  1996 the  Company introduced  FAXSAV PLUS,  a new
"virtual real-time" service which  is designed to  provide reliable delivery  of
facsimile  transmissions at substantially reduced  costs. The Company utilizes a
combination  of  its  traditional   telephony-based  network  and  its   growing
Internet-based  network  to deliver  FAXSAV PLUS  transmissions to  fax machines
worldwide. The Company is currently implementing the FAXSAV PLUS service with  a
two-tiered pricing structure. Pricing for delivery to the key telecommunications
markets  currently  targeted  for  Internet  node  deployment  is  based  on the
economics of delivery through a planned  Internet backbone, even if the  Company
has  not  yet  deployed Internet-capable  facsimile  nodes in  such  markets. At
September 1, 1996, the Company had not yet deployed Internet-capable nodes in 27
of such currently targeted markets.  Pricing for delivery to other  destinations
worldwide  continues  to  be based  on  the  economics of  delivery  through the
Company's telephony-based network, which prices may or may not be reduced in the
event that the Company deploys Internet-capable facsimile nodes in such markets.
The  Company  estimates  that  this  pricing  structure  enables  reductions  of
approximately  40%  to  70%  in  the  international  fax  bills  of  FAXSAV PLUS
customers. FAXSAV  PLUS customers  are charged  on a  per-minute basis  for  the
transmission time to the destination fax machine, and are billed monthly.
    
 
    FAXSAV FOR INTERNET SUITE OF SERVICES
 
   
    The  FAXSAV FOR INTERNET suite of  services, introduced in stages during the
first half of 1996, enables Internet-connected customers to send faxes  directly
from their computer desktops, either from their e-mail package or from a Windows
software  application, through  the Internet to  fax machines  worldwide via the
FaxSav network. As of June 30, 1996, there were more than 1,000 registered users
of the FAXSAV FOR INTERNET suite of services. The Company's World Wide Web  site
includes a detailed explanation of these services, installation instructions and
service  registration forms. Customers  are charged on a  per-page basis for the
FAXSAV FOR INTERNET  suite of services  and generally are  billed in advance  of
use.  The FAXSAV FOR INTERNET suite  of services includes the following discrete
services:
    
 
    - FAXLAUNCHER enables  customers to  fax documents  created in  any  Windows
      application  directly from  an Internet-connected computer  desktop to fax
      machines worldwide. FAXLAUNCHER  also supports  documents scanned  through
      sheet-fed scanners manufactured by Visioneer, Inc., Hewlett-Packard Co. or
      Compaq Computer Corporation. FAXLAUNCHER software is provided to customers
      in diskette form or it may be downloaded from the Company's World Wide Web
      site.
 
    - FAXMAILER enables customers to transmit messages from e-mail packages over
      the Internet to the FaxSav network for delivery to fax machines worldwide.
      FAXMAILER  provides the desktop e-mail customer  with the ability to reach
      the fax machine of  anyone not yet connected  to the Internet without  the
      necessity  of creating hard copy and manually sending a fax. Customers may
      register for the FAXMAILER  service through the  Company's World Wide  Web
      site.
 
    - FAXSCAN enables customers to send documents scanned in any TWAIN-compliant
      scanner  over  the Internet  to  the FaxSav  network  for delivery  to fax
      machines worldwide. The combination of a scanner and FAXSCAN software puts
      a virtual fax machine at the desktop for the customer. FAXSCAN software is
      provided to customers in diskette form.
 
                                       33
<PAGE>
    FAXSAV CUSTOM CORPORATE SOLUTIONS
 
    FAXSAV CUSTOM CORPORATE SOLUTIONS are specialized services developed by  the
Company to meet customer needs for specific volume fax applications. FaxSav will
custom tailor a software, networking and telecommunications solution designed to
provide the customer with additional savings in time and money.
 
CUSTOMER SUPPORT SERVICES
 
    The  Company believes that customer  support is important in differentiating
its facsimile delivery  services from  other delivery  approaches. The  customer
support  services provided by the Company  include installation assistance on an
as-requested basis, facilitation of international fax completion and  monitoring
the  performance of FAXSAV  CONNECTORS. The Company  currently provides customer
support and network/ FAXSAV CONNECTOR monitoring functions 12 hours per day and,
beginning in the  fourth quarter of  1996, intends to  provide such services  24
hours  per day, seven days per week.  The Company's support personnel respond to
telephone inquiries and e-mail inquiries. The Company also provides  information
about its services and new desktop software upgrades on its World Wide Web site.
 
    To  provide  immediate  response  to  customer  inquiries,  the  Company has
developed a wide area network that provides a real-time fax tracking system  and
allows network operations and customer service personnel to redirect, reschedule
or  repair fax  transmissions that  are experiencing  completion difficulty. The
system accesses fax traffic information via  an Oracle database that is  updated
from  the Company's  two switching  nodes in the  United States  and provides an
on-line connectivity to the Company's master customer database.
 
SALES AND MARKETING
 
    DOMESTIC SALES AND MARKETING
 
    The Company offers its services in the United States through multiple  sales
channels  which include direct mail and direct response programs, a direct field
sales  force,  an  agent  and  dealer  distribution  network,  and   promotional
activities at trade shows and on the FaxSav World Wide Web site.
 
    The  Company's  direct mail  and direct  response  efforts are  supported by
multiple telemarketing firms.  The Company compensates  its telemarketing  firms
based  on a combination of the number  of work-hours dedicated to FaxSav and the
number of sales generated.
 
    During 1995 the  Company increased its  sales efforts by  creating a  direct
field  sales force to address the specialized faxing needs of major accounts and
to manage  and support  the Company's  agent channel.  The Company's  agent  and
dealer   distribution  network  consists  of  organizations  which  sell  office
equipment, office  supplies  and  telephony services,  as  well  as  independent
marketing  companies. These agents offer FaxSav services as a companion offering
to their other products lines. The  Company is also exploring relationships  for
bundling  FAXSAV FOR  INTERNET suite of  services with the  products of computer
hardware, software and Internet services companies.
 
   
    The Company  has  used  computer  and Internet  trade  shows  as  forums  to
introduce the FAXSAV FOR INTERNET suite of services to prospective customers and
partners.  The  Company's  promotions  have included  the  distribution  of free
software to access its services  and free faxing during  a trial period and  the
Company  currently offers  10 free  pages of faxes  to each  new subscriber that
registers through  the Company's  World  Wide Web  home  page. The  Company  has
promoted  its FAXLAUNCHER  software on the  World Wide Web  since February 1996.
Since that time, as of  June 30, 1996 approximately  3,000 copies of the  FAXSAV
FOR  INTERNET suite of services  have been downloaded and  more than 1,000 users
have registered with the Company.
    
 
    As of June 30, 1996, FaxSav employed 23 sales and marketing representatives,
all in the United States. In connection with its price leadership strategy,  the
Company  intends to  intensify all aspects  of its domestic  sales and marketing
efforts, including increased direct mail and telemarketing activities and hiring
additional direct sales representatives. See "--The FaxSav Strategy."

    INTERNATIONAL ALLIANCES
   
    In connection with the installation  of Internet-capable facsimile nodes  in
foreign  countries, the Company is seeking to form strategic sales and marketing
alliances with local  Internet service  providers, telecommunications  companies
and  resellers. The Company anticipates that  these organizations will use their
knowledge of the  local market, language,  customs and regulations,  as well  as
their  existing distribution,  customer support and  billing infrastructures, to
establish, grow and properly service  an international FaxSav customer base.  In
return,  the  Company  is  offering  these  organizations  either  exclusive  or
non-exclusive rights to market the  Company's services in their territories  and
offering  to provide such services at a discount to the Company's retail prices.
To date the Company has formed preliminary strategic alliances with companies in
Bermuda, Hong  Kong,  Japan,  Korea, Lebanon,  the  Philippines,  Singapore  and
Taiwan.  In addition,  the Company has  formed a  preliminary strategic alliance
with a United States corporation regarding activities in Mexico. The Company has
entered into  non-binding letters  of  intent with  respect to  these  strategic
alliances.
    
 
   
    In  addition to the strategic alliances, the Company is developing a network
of commission-based agents to sell the FAXSAV FOR INTERNET suite of services  in
foreign  markets. To date,  this network consists of  31 agents representing the
Company in 23 foreign markets. The Company also intends to implement a  rebiller
program  for those agents  who have the infrastructure  to generate invoices and
perform collections. It is anticipated  that, under this program,  participating
agents  will be  provided detailed  billing information  on their  accounts from
which they  can  create  and  distribute invoices  in  the  local  language  and
currency, and locally service customer billing inquiries.
    
 
CUSTOMERS
   
    The  Company  sells  its  services  primarily  to  small  and  medium  sized
businesses with  international  document transmission  needs  and, to  a  lesser
extent,   to  international  departments  and  divisions  of  larger  companies.
Customers can install  FaxSav's services  at individual fax  machine or  desktop
locations, across departments or throughout organizations by simply plugging the
FAXSAV  CONNECTOR, a small proprietary device, between their fax machine and the
telephone jack or by simply installing FaxSav's desktop software on an  Internet
connected  personal computer. Through 1995, all  of the Company's customers were
located in  the United  States,  and their  fax  messages to  international  and
domestic  destinations accounted for approximately 85% and 15%, respectively, of
the Company's total 1995 revenues. In 1996, with the introduction of the  FAXSAV
FOR INTERNET suite of services, the Company began to expand its customer base to
include  foreign customers. As  of June 30, 1996,  the Company had approximately
7,200  customers  utilizing  its  traditional  services  and  more  than   1,000
registered users of the Company's desktop services. No single customer accounted
for  more than 1% of the  Company's revenues in 1995 or  in the six months ended
June 30, 1996. The following is a sampling of the Company's customers, separated

COMPETITION
 
   
    The market for facsimile transmission services is intensely competitive  and
there  are limited barriers to entry.  The Company expects that competition will
intensify in  the future.  The  Company believes  that  its ability  to  compete
successfully  will depend upon  a number of  factors, including market presence;
the capacity,  reliability  and  security of  its  network  infrastructure;  the
pricing  policies of its competitors and  suppliers; the timing of introductions
of new services and service enhancements by the Company and its competitors; and
industry and general economic trends. A key element of the Company's strategy is
to expand its market presence by  leveraging its price leadership strategy  both
domestically  and internationally. The  Company intends to  maintain and improve
the capacity, reliability  and security  of its  network infrastracture  through
continued  research  and  development  activities  and  will  continue  to place
significant emphasis on the ongoing development of new services and applications
of its existing services. See "-- The FaxSav Strategy."
    
 
    The Company's current  and prospective competitors  generally fall into  the
following  groups: (i) telecommunication  companies, such as  AT&T, MCI, Sprint,
LDDS WorldCom and the regional Bell operating companies; (ii) telecommunications
resellers, such as Frontier Corporation, Biztel Corporation and Eastern  Telecom
Corporation;  (iii) Internet service providers, such as Uunet Technologies, Inc.
and  NETCOM  On-Line  Communications  Services,  Inc.;  (iv)  on-line   services
providers,  such as  America Online,  Inc. and  CompuServe Incorporated  and (v)
direct fax  delivery  competitors,  including  Xpedite  Systems,  Inc.  and  Fax
International,  Inc.  Many of  these competitors  have greater  market presence,
engineering  and  marketing  capabilities,  and  financial,  technological   and
personnel  resources than those available to the  Company. As a result, they may
be able to develop and  expand their communications and network  infrastructures
more  quickly, adapt more swiftly to new or emerging technologies and changes in
customer requirements,  take advantage  of acquisition  and other  opportunities
more  readily, and devote greater  resources to the marketing  and sale of their
products and  services than  can the  Company. Further,  the foundation  of  the
Company's  telephony network  infrastructure consists  of the  right to  use the
telecommunications  lines  of  several  of  the  above-mentioned  long  distance
carriers,  including LDDS WorldCom and MCI. There can be no assurance that these
companies will not discontinue or  otherwise alter their relationships with  the
Company in a manner that would have a material adverse effect upon the Company's
business,  financial condition and  results of operations.  In addition, current
and  potential  competitors  have  established  or  may  establish   cooperative
relationships  among themselves or with third parties to increase the ability of
their services to  address the needs  of the Company's  current and  prospective
customers.  Accordingly, it is possible that  new competitors or alliances among
competitors may emerge and rapidly acquire significant market share. In addition
to direct competitors, many of the Company's larger potential customers may seek
to internally fulfill their  fax communication needs  through the deployment  of
their own computerized fax communications systems or network infrastructures for
intra-company faxing.
 
    Increased  competition is  likely to  result in  price reductions  and could
result in reduced gross margins and  erosion of the Company's market share,  any
of  which  would  have a  material  adverse  effect on  the  Company's business,
financial condition and results  of operations. There can  be no assurance  that
the  Company  will be  able to  compete successfully  against current  or future
competitors or  that competitive  pressures  will not  have a  material  adverse
effect on the Company's business, financial condition and results of operations.
 
INTELLECTUAL PROPERTY
 
    The  Company's  success is  dependent upon  its proprietary  technology. The
Company relies primarily on a  combination of contract, copyright and  trademark
law,  trade secrets,  confidentiality agreements  and contractual  provisions to
protect its proprietary rights. The Company has patent applications pending  for
its   FAXSAV  CONNECTOR  and   for  its  "e-mail   Stamps"  security  technology
incorporated into its FAXMAILER service. There can be no assurance that  patents
will issue from such applications or that present or future patents will provide
sufficient  protection to the Company's present or future technologies, products
and processes.  In addition,  there can  be no  assurance that  others will  not
independently develop substantially equivalent proprietary information or obtain
access  to the Company's know-how. Despite  the Company's efforts to protect its
proprietary rights,  unauthorized parties  may attempt  to copy  aspects of  the
Company's services or
 
                                       36
<PAGE>
to  obtain  and use  information  that the  Company  regards as  proprietary. In
addition, the  laws of  some  foreign countries  do  not protect  the  Company's
proprietary rights to the same extent as do the laws of the United States. There
can  be  no  assurance  that the  steps  taken  by the  Company  to  protect its
proprietary rights will be adequate or  that the Company's competitors will  not
independently develop technologies that are substantially equivalent or superior
to the Company's technologies.
 
    The  Company is  not aware  that any  of its  services, trademarks  or other
proprietary rights infringe  the proprietary rights  of third parties.  However,
the  Company received  a letter in  the third  quarter of 1995  stating that the
Company's FAXSAV  CONNECTOR  may  be  utilizing  a  call  diversion  methodology
patented  by a third party. To the Company's knowledge, such third party has not
initiated any  suit, action,  proceeding or  investigation relating  to  alleged
infringement by the Company of such patent. There can be no assurance that third
parties  will not assert infringement claims  against the Company in the future.
Patents  have  been  granted  recently   on  fundamental  technologies  in   the
communications and desktop software areas, and patents may issue which relate to
fundamental  technologies  incorporated  in the  Company's  services.  As patent
applications in the United  States are not publicly  disclosed until the  patent
issues,  applications may  have been  filed which,  if issued  as patents, could
relate to the Company's services. The Company could incur substantial costs  and
diversion of management resources with respect to the defense of any claims that
the Company has infringed upon the proprietary rights of others, which costs and
diversion  could  have  a material  adverse  effect on  the  Company's business,
financial condition and results of operations. Furthermore, parties making  such
claims  could  secure  a  judgment  awarding  substantial  damages,  as  well as
injunctive or other equitable relief which could effectively block the Company's
ability to license and  sell its services  in the United  States or abroad.  Any
such  judgment could have  a material adverse effect  on the Company's business,
financial condition and results of operations. In the event a claim relating  to
proprietary  technology  or information  is  asserted against  the  Company, the
Company may  seek  licenses to  such  intellectual  property. There  can  be  no
assurance,  however, that licenses could be  obtained on terms acceptable to the
Company, or at all. The failure to obtain any necessary licenses or other rights
could have  a  material adverse  effect  on the  Company's  business,  financial
condition and results of operations.
 
GOVERNMENT REGULATION
 
    The  Company is subject  to regulation by  the FCC, by  various state public
service and public utility commissions  and by various international  regulatory
authorities.
 
    FaxSav  is licensed by  the FCC as  an authorized telecommunications company
and is classified as a "non-dominant interexchange carrier." Generally, the  FCC
has  chosen not to exercise its statutory  power to closely regulate the charges
or  practices  of  non-dominant  carriers.  Nevertheless,  the  FCC  acts   upon
complaints   against  such  carriers  for   failure  to  comply  with  statutory
obligations or with the FCC's rules, regulations and policies. The FCC also  has
the power to impose more stringent regulatory requirements on the Company and to
change  its regulatory  classification. There can  be no assurance  that the FCC
will not change the Company's regulatory classification or otherwise subject the
Company to more burdensome regulatory requirements.
 
    In order to provide  intrastate service, the Company  is required to  obtain
various  certifications from the public service or public utility commissions of
each state,  or  to  register or  be  found  exempt from  registration  by  such
commissions.  The Company has made the filings and taken the actions it believes
are necessary  to  allow  the  limited intrastate  services  that  it  currently
provides.
 
    In  connection with the anticipated  deployment of Internet-capable nodes in
countries throughout  the world,  the  Company will  be  required to  satisfy  a
variety  of foreign regulatory requirements. The  Company intends to explore and
seek to comply  with these  requirements on  a country-by-country  basis as  the
deployment  of  Internet-capable  facsimile  nodes continues.  There  can  be no
assurance that the Company will be  able to satisfy the regulatory  requirements
in each of the countries currently targeted for node deployment, and the failure
to  satisfy such requirements may prevent  the Company from installing Internet-
capable facsimile nodes  in such countries.  The failure to  deploy a number  of
such  nodes  could have  a material  adverse effect  on the  Company's business,
operating results and financial condition.
 
                                       37
<PAGE>
   
    The Company's  nodes  and its  FAXLAUNCHER  service utilize  RSA  encryption
technology  in connection  with the  routing of  customer documents  through the
Internet. The export of  such encryption technology is  regulated by the  United
States  government.  The Company  is seeking  authority for  the export  of such
encryption technology and anticipates that  authority will be granted to  export
such  technology worldwide, other than to  Cuba, Iran, Libya, North Korea, Sudan
and Syria. Nevertheless, there can be  no assurance that such authority will  be
granted  or, if granted, that it will not be revoked or modified at any time for
any particular  jurisdiction  or  in  general. In  addition,  there  can  be  no
assurance  that such export controls, either in  their current form or as may be
subsequently enacted, will  not limit  the Company's ability  to distribute  its
services outside of the United States or electronically. While the Company takes
precautions  against unlawful exportation of its  software, the global nature of
the  Internet  makes  it  virtually   impossible  to  effectively  control   the
distribution  of its services. Moreover, future  Federal or state legislation or
regulation may further limit levels of encryption or authentication  technology.
Any  such  export  restrictions,  the  unlawful  exportation  of  the  Company's
services, new legislation or regulation could have a material adverse effect  on
the Company's business, financial condition and results of operations.
    
 
EMPLOYEES
 
    As of June 30, 1996, the Company had 74 full-time employees, including 11 in
research  and development, 26 in network operations and support, 23 in sales and
marketing and 14 in finance and  administration. In addition, at June 30,  1996,
the  Company was utilizing the services  of 4 software engineer consultants. The
Company's employees are not covered by any collective bargaining agreements. The
Company believes that its relations with its employees are good.
 
FACILITIES
 
    The Company's corporate headquarters  are located in  Edison, New Jersey  in
facilities  consisting  of  approximately  8,400  square  feet  of  office space
occupied under a lease  expiring in July 1998.  In addition, the Company  leases
sales  offices  in the  San Francisco  and Dallas  metropolitan areas.  While it
believes that these facilities are adequate  for its present needs, the  Company
is  continually reviewing its  needs and may  add facilities in  the future. The
Company believes  that  any required  additional  space would  be  available  on
commercially  reasonable terms.  Finally, in  connection with  its deployment of
Internet-capable facsimile  nodes,  the  Company  has  entered  into,  and  will
continue to enter into, short-term leases in telehousing facilities worldwide.
 
LEGAL PROCEEDINGS
 
    The Company is not a party to any material legal proceedings. The initiation
of  any litigation, including any action claiming infringement by the Company of
intellectual property  rights,  could have  a  material adverse  effect  on  the
Company's  business, financial  condition and  results of  operations. See "Risk
Factors-- Limited  Protection of  Intellectual Property  Rights; Risk  of  Third
Party Claims of Infringement."

1996 STOCK OPTION/STOCK ISSUANCE PLAN
 
   
    The  Company's 1996  Stock Option/Stock Issuance  Plan (the  "1996 Plan") is
intended to serve  as the successor  equity incentive program  to the  Company's
1990  Stock Option Plan (the  "Predecessor Plan"). The 1996  Plan was adopted by
the Board  of  Directors, effective  June  30, 1996,  and  was approved  by  the
stockholders  in  August  1996.  1,794,175  shares  of  Common  Stock  have been
authorized for issuance under the 1996 Plan. This share reserve is comprised  of
the  shares which  remained available for  issuance under  the Predecessor Plan,
including  the  shares  subject  to  outstanding  options  thereunder  plus   an
additional  increase  of  555,556  shares.  The  outstanding  options  have been
incorporated into the 1996 Plan and no further option grants will be made  under
the  Predecessor Plan. The incorporated options  will continue to be governed by
their existing terms, unless the Plan Administrator elects to extend one or more
features of the 1996 Plan to
    
 
                                       42
<PAGE>
   
those options.  However,  the outstanding  options  under the  Predecessor  Plan
contain  substantially the  same terms  and conditions  specified below  for the
Discretionary Option  Grant  Program in  effect  under  the 1996  Plan.  Of  the
1,794,175  shares of Common  Stock authorized for issuance  under the 1996 Plan,
533,334 are currently available for grant.  In no event may any one  participant
in  the 1996 Plan receive option grants  or direct stock issuances for more than
300,000 shares in the aggregate.
    
 
    The  1996  Plan  is  divided   into  three  separate  components:  (i)   the
Discretionary  Option Grant Program under which eligible individuals may, at the
discretion of the Plan Administrator, be  granted options to purchase shares  of
Common  Stock at an exercise price not less  than 85% of their fair market value
on the grant date, (ii) the Stock Issuance Program under which such  individuals
may,  in the Plan  Administrator's discretion, be issued  shares of Common Stock
directly, through the purchase of  such shares at a price  not less than 85%  of
their  fair market  value at  the time  of issuance  or as  a bonus  tied to the
performance of services and (iii) the Automatic Option Grant Program under which
option grants  will automatically  be  made at  periodic intervals  to  eligible
non-employee  Board members  to purchase shares  of Common Stock  at an exercise
price equal to 100% of their fair market value on the grant date.
 
    The Discretionary Option Grant Program  and the Stock Issuance Program  will
be  administered by  the Compensation  Committee. The  Compensation Committee as
Plan Administrator will  have complete  discretion to  determine which  eligible
individuals  are to receive option grants or  stock issuances, the time or times
when such option grants or stock issuances are to be made, the number of  shares
subject  to each  such grant or  issuance, the  status of any  granted option as
either an  incentive stock  option or  a non-statutory  stock option  under  the
Federal  tax laws, the vesting schedule to be  in effect for the option grant or
stock issuance and the maximum  term for which any  granted option is to  remain
outstanding.
 
    Upon an acquisition of the Company by merger or asset sale, each outstanding
option  and unvested stock issuance will be subject to accelerated vesting under
certain circumstances.
 
    Stock  appreciation   rights  are   authorized   for  issuance   under   the
Discretionary  Option Grant Program which provide  the holders with the election
to surrender their outstanding options for an appreciation distribution from the
Company equal to the excess of (i) the fair market value of the vested shares of
Common Stock subject to the surrendered option over (ii) the aggregate  exercise
price  payable for such  shares. Such appreciation distribution  may be made, at
the sole direction of  the Plan Administrator,  in cash or  in shares of  Common
Stock.
 
    The  Plan  Administrator has  the authority  to  effect the  cancellation of
outstanding options  under the  Discretionary  Option Grant  Program  (including
options  incorporated from the Predecessor Plan) in  return for the grant of new
options for the same or different number of option shares with an exercise price
per share based upon the fair market value of the Common Stock on the new  grant
date.
 
   
    Under  the Automatic Option Grant Program, each individual who first becomes
a non-employee Board member on or after the date the Underwriting Agreement  for
this  offering is executed will receive a  22,222 share option grant on the date
such individual joins the  Board, provided such individual  has not been in  the
prior  employ of the Company. In  addition, at each Annual Stockholders Meeting,
beginning with the 1997  Annual Meeting, each individual  who is to continue  to
serve  as a  non-employee Board  member after  the meeting  and has  served as a
non-employee board member  for at least  six months will  receive an  additional
option  grant  to purchase  4,444 shares  of  Common Stock  whether or  not such
individual has been in the prior employ of the Company.
    
 
    Each automatic  grant will  have a  term  of 10  years, subject  to  earlier
termination  following the optionee's cessation of Board service. Each automatic
option will  be  immediately exercisable;  however,  any shares  purchased  upon
exercise  of  the option  will be  subject to  repurchase should  the optionee's
service as a non-employee Board member cease prior to vesting in the shares. The
initial 22,222  share  grant will  vest  in  four equal  and  successive  annual
installments  over the optionee's period of Board service. Each additional 4,444
share grant  will vest  upon the  optionee's  completion of  one year  of  Board
service measured from the
 
                                       43
<PAGE>
grant  date. However,  each outstanding  option will  immediately vest  upon (i)
certain changes in the ownership or control of the Company or (ii) the death  or
disability of the optionee while serving as a Board member.
 
   
    The  Board may amend or modify the 1996 Plan at any time. The 1996 Plan will
terminate on June 29, 2006, unless sooner terminated by the Board or pursuant to
certain other provisions of the Plan.
    
 
EMPLOYMENT CONTRACTS AND CHANGE OF CONTROL ARRANGEMENTS
 
    The Company does not presently have any employment contracts in effect  with
the Chief Executive Officer or any of the other Named Executive Officers.
 
    The  Compensation Committee as Plan Administrator of the 1996 Plan will have
the authority to  provide for the  accelerated vesting of  the shares of  Common
Stock subject to outstanding options held by the Chief Executive Officer and any
other  executive  officer  or  the  shares of  Common  Stock  subject  to direct
issuances held by such individual, in connection with certain changes in control
of the  Company  or  the  subsequent termination  of  the  officer's  employment
following the change in control event.
 
    Each  of the  Company's directors  and officers,  with the  exception of Mr.
Dunfield and Mr. Labant, is party to an agreement with the Company providing for
the acceleration of the vesting of options to purchase Common Stock held by such
director and officer in  the event of the  involuntary removal or dismissal  (as
defined  in such agreement)  of such director  or officer in  connection with an
acquisition (as defined in such agreement)  of the Company. Such agreements  may
have  the effect of delaying  or preventing a change  in control of the Company,
and therefore, could adversely affect the  price of the Company's Common  Stock.
The  Company has  also agreed to  pay Mr.  Murawski $12,500 per  month, plus all
benefits, for up to three months after the termination of his employment without
cause.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Company's  Compensation Committee  consists  of two  outside  directors,
Jeffrey  Drazan  and Peter  Howley. Certain  members of  the Company's  Board of
Directors have  been parties  to  transactions with  the Company.  See  "Certain
Transactions."  Although neither  Mr. Drazan  nor Mr.  Howley was  an officer or
executive of the  Company in  fiscal year 1995,  from October  1991 to  November
1991,  Mr. Drazan served as  interim president of the  Company until a successor
was found for the individual previously serving in that position.
 
401(K) PLAN
 
    The Company participates in a tax-qualified employee savings and  retirement
plan  (the "401(k) Plan") which covers all of the Company's employees with three
months of service who are at least 21 years of age. Pursuant to the 401(k) Plan,
employees  may  elect  to  reduce  their  current  compensation  by  up  to  the
statutorily  prescribed  annual  limit and  have  the amount  of  such reduction
contributed to  the 401(k)  Plan. The  401(k) Plan  permits additional  matching
contributions  by the Company on behalf of  all participants in the 401(k) Plan,
although as of the date of this Prospectus, the Company has elected not to match
participant contributions. The 401(k) Plan is intended to qualify under  Section
401  of the Internal Revenue Code of  1986, as amended, so that contributions by
employees or  by the  Company to  the 401(k)  Plan, and  income earned  on  plan
contributions,  are not  taxable to  employees until  withdrawn from  the 401(k)
Plan, and so that contributions  by the Company, if  any, will be deductible  by
the  Company when made. The  trustee under the 401(k)  Plan, at the direction of
each participant,  invests  the  assets  of  the 401(k)  Plan  in  a  number  of
investment options.
 
KEY-PERSON LIFE INSURANCE
 
    The  Company does  not maintain  key-person life  insurance policies  on the
lives of any of its executive officers.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company's  Certificate of  Incorporation provides  that, except  to  the
extent  prohibited by the Delaware General  Corporation Law, its directors shall
not be personally liable to the Company or its stockholders for monetary damages
for  any  breach  of  fiduciary  duty   as  directors  of  the  Company.   Under
 
                                       44
<PAGE>
Delaware  law, the directors have  a fiduciary duty to  the Company which is not
eliminated by  this  provision  of  the Certificate  of  Incorporation  and,  in
appropriate  circumstances, equitable remedies such as injunctive or other forms
of non-monetary relief will  remain available. In  addition, each director  will
continue  to  be subject  to  liability under  Delaware  law for  breach  of the
director's duty of loyalty to the Company, for acts or omissions which are found
by a  court of  competent jurisdiction  to be  not in  good faith  or  involving
intentional  misconduct, for knowing  violations of law,  for actions leading to
improper personal  benefit to  the director,  and for  payment of  dividends  or
approval  of stock  repurchases or redemptions  that are  prohibited by Delaware
law. This provision also does  not affect the directors' responsibilities  under
any  other  laws,  such as  the  Federal  securities laws  or  state  or Federal
environmental laws.  If commercially  feasible, the  Company intends  to  obtain
liability insurance for its officers and directors.
 
    The  Certificate  of  Incorporation  also  provides  that  the  Company  may
indemnify, to  the fullest  extent  permitted by  Section  145 of  the  Delaware
General  Corporation Law, all of its  present and former officers and directors,
and any party agreeing to serve as an officer, director or trustee of any entity
at the Company's request,  in connection with any  civil or criminal  proceeding
threatened  or instituted against  such party by reason  of actions or omissions
while serving in such capacity. Indemnification by the Company includes  payment
of  expenses in defense of the indemnified party in advance of any proceeding or
final disposition  thereof.  The  rights to  indemnification  provided  in  this
provision  do not preclude  the exercise of any  other indemnification rights by
any party pursuant  to any law,  agreement or  vote of the  stockholders or  the
disinterested directors of the Company.
 
    Section  145 of  the Delaware General  Corporation Law  generally allows the
Company to indemnify the  parties described in the  preceding paragraph for  all
expenses,   judgments,  fines  and  amounts  in  settlement  actually  paid  and
reasonably incurred in  connection with any  proceedings so long  as such  party
acted  in good faith and in a manner reasonably believed to be in or not opposed
to the Company's best interests and,  with respect to any criminal  proceedings,
if  such party  had no  reasonable cause  to believe  his or  her conduct  to be
unlawful. Indemnification may  only be  made by  the Company  if the  applicable
standard  of conduct set  forth in Section  145 has been  met by the indemnified
party upon a determination made (1) by the Board of Directors by a majority vote
of the directors who are not parties to such proceedings (even though less  than
a  quorum), or  (2) if  there are  no such  directors, or  if such  directors so
direct, by  independent  legal counsel  in  a written  opinion,  or (3)  by  the
stockholders.

AGREEMENTS WITH TELSTRA INCORPORATED
 
    In March  1996,  the  Company  repurchased  8,655,510  shares  of  Series  D
Preferred  Stock  held  by  Telstra  Incorporated  ("Telstra  Incorporated"), an
indirect wholly-owned subsidiary of Telstra, at a price of $0.25 per share. As a
result of such repurchase,  certain covenants in  favor of Telstra  Incorporated
contained  in the Series  D Preferred Stock Purchase  Agreement (as amended, the
"Telstra Purchase Agreement"),  were eliminated,  although Telstra  Incorporated
retained  the  right to  designate  one member  of  FaxSav's Board  of Directors
(currently, Mr.  Dunfield). Such  designation  right, and  all other  rights  of
Telstra  Incorporated under the Telstra Purchase Agreement, shall terminate upon
the consummation of this offering. In  March 1996, Telstra Incorporated and  the
Company  entered into an agreement providing  for the acceleration of vesting of
all Common Stock options granted  to Telstra Incorporated for the  participation
of  its designees on the Company's Board of Directors that are scheduled to vest
and become  exercisable during  the 24-month  period following  the  involuntary
removal  without cause (as  defined in such  agreement) of any  such director in
connection with an acquisition (as defined in such agreement) of the Company.
 
   
    The Company and  Telstra Incorporated  are parties to  a Traffic  Agreement,
effective  November  1994  (the "Traffic  Agreement").  Under the  terms  of the
Traffic Agreement, the Company will exclusively use Telstra's (or its  nominees)
"WorldFax"  service for  the Company's outbound  traffic from  the United States
provided that such service is offered at a rate which the Company can reasonably
demonstrate that it can secure from  a recognized service provider for  services
of equivalent quality on comparable terms over the same time period. The Traffic
Agreement  has a five  year term which  began in late  1995, upon the commercial
commencement of Telstra's "WorldFax" service in the United States.

    Stock  beneficially  owned by  Telstra  Incorporated, which  shares  will be
    converted into  961,723 shares  of Common  Stock upon  consummation of  this

                          DESCRIPTION OF CAPITAL STOCK
 
    Upon  the consummation of this offering, the authorized capital stock of the
Company will consist of 40,000,000 shares of Common Stock, $0.01 par value,  and
1,000,000 shares of Preferred Stock, $0.01 par value.
 
COMMON STOCK
 
   
    Each  holder of Common  Stock is entitled  to one vote  for each share held.
Following this offering, the holders of Common Stock, voting as a single  class,
will  be entitled to elect  all of the directors of  the Company. In all matters
other than  the  election  of  directors,  when  a  quorum  is  present  at  any
stockholders' meeting, the affirmative vote of the majority of shares present in
person  or represented by  proxy shall decide any  question before such meeting.
Directors are elected  by a  plurality of  the votes  of the  shares present  in
person or represented by proxy at a stockholders' meeting. The holders of Common
Stock  are entitled to receive ratably such  dividends as may be declared by the
Board of Directors out of  funds legally available therefor.  In the event of  a
liquidation,  dissolution or winding up of  the Company, holders of Common Stock
would be entitled to share in  the Company's assets remaining after the  payment
of liabilities and the satisfaction of any liquidation preference granted to the
holders  of any outstanding  shares of Preferred Stock.  Holders of Common Stock
have no preemptive or other subscription rights. The shares of Common Stock  are
not  convertible into any other security. The outstanding shares of Common Stock
are, and the shares being offered hereby will be, upon issuance and sale,  fully
paid and nonassessable.
    
 
   
    At  August 31, 1996, there were 8,170,490 shares of Common Stock outstanding
(after giving effect to  the conversion of all  outstanding shares of  Preferred
Stock  into Common Stock) and held of record by 120 stockholders, and options to
purchase an aggregate of 1,238,619 shares of Common Stock were also outstanding.
See "Management--1996  Stock Option/Stock  Issuance Plan."  In addition,  as  of
August  31, 1996, warrants to purchase an  aggregate of 138,385 shares of Common
Stock were outstanding.
    
 
PREFERRED STOCK
 
   
    Upon the consummation of  this offering, the Company  will be authorized  to
issue 1,000,000 shares of Preferred Stock with such voting rights, designations,
preferences  and rights,  and such  qualifications, limitations  or restrictions
thereof, as  may be  determined by  the Board  of Directors  providing for  such
series.  Although  the Company  has  no current  plans  to issue  any  shares of
Preferred Stock,  the issuance  of  Preferred Stock  or  of rights  to  purchase
Preferred Stock could be used to discourage an unsolicited acquisition proposal.
In  addition, the possible issuance of  Preferred Stock could discourage a proxy
contest, make  more difficult  the acquisition  of a  substantial block  of  the
Company's Common Stock or limit the price that investors might be willing to pay
in the future for shares of the Company's Common Stock.
    
 
    The  Company believes that the Preferred Stock will provide the Company with
increased flexibility in structuring possible future financing and acquisitions,
and in meeting other  corporate needs that might  arise. Having such  authorized
shares  available  for  issuance  will  allow the  Company  to  issue  shares of
Preferred Stock  without  the  expense  and delay  of  a  special  stockholders'
meeting.  The authorized shares of Preferred Stock,  as well as shares of Common
Stock, will be available  for issuance without  further action by  stockholders,
unless  such action  is required  by applicable  law or  the rules  of any stock
exchange on which the Company's securities may be listed.
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
 
   
    After this offering, the holders of approximately 8,017,000 shares of Common
Stock, and the holders of warrants  to purchase an additional 138,385 shares  of
Common  Stock (the "Registrable Securities") will  be entitled to certain demand
rights with respect to the registration of the Registrable Securities under  the
Securities  Act. Under the  terms of the  agreement between the  Company and the
holders of the Registrable Securities,  subject to certain restrictions, at  any
time  (a) after the earlier of (i) three  (3) months after the effective date of
the Registration  Statement  of which  this  Prospectus  forms a  part  or  (ii)
February  1, 1997, the holders  of more than 50%  of the Registrable Securities,
and (b) after this offering is  complete, holders proposing to sell  Registrable
Securities  at a reasonably  anticipated aggregate offering  price to the public
(net of any underwriter's discount or commissions) of $10,000,000, are  entitled
to demand that the Company
    
 
                                       50
<PAGE>
   
register  their Registrable Securities under the  Securities Act. The Company is
not required to effect more than two such registrations pursuant to such  demand
registration  rights. In addition, under such agreement, if the Company proposes
to register any of its securities under  the Securities Act, either for its  own
account  or for  the account of  other security  holders exercising registration
rights, subject  to  certain  restrictions,  such  holders  of  the  Registrable
Securities  and  the holders  of 83,741  shares of  Common Stock  (the "Founders
Registrable Securities") are  entitled to  notice of such  registration and  are
entitled  to  include  their  registrable  securities  therein.  The  Company is
required  to  include  any   Registrable  Securities  or  Founders   Registrable
Securities  in an  unlimited number of  such registrations. Once  the Company is
eligible to use a Form S-3  registration statement to register shares of  Common
Stock,  subject  to  certain restrictions,  holders  of 20%  of  the Registrable
Securities are also entitled to require the Company on two separate occasions in
any twelve month period to file a Form S-3 registration statement under the  Act
at   the  Company's  expense  with  respect  to  their  Registrable  Securities.
Registration  of  Registrable  Securities  or  Founders  Registrable  Securities
pursuant  to such  rights would result  in such shares  becoming freely tradable
without restriction under the Securities Act immediately upon the  effectiveness
of  such  registration. In  connection with  this offering,  the holders  of the
Registrable Securities and  the Founders Registrable  Securities have agreed  to
waive  their  registration  rights  until  180  days  after  the  date  of  this
Prospectus.
    
 
DELAWARE LAW AND CERTAIN PROVISIONS OF THE COMPANY'S RESTATED CERTIFICATE
 OF INCORPORATION AND BY-LAWS
 
    The Company  is subject  to the  provisions of  Section 203  of the  General
Corporation  Law  of Delaware.  Section 203  prohibits a  publicly-held Delaware
corporation from  engaging  in  a "business  combination"  with  an  "interested
stockholder"  for a period of  three years after the  date of the transaction in
which  the  person  became  an  interested  stockholder,  unless  the   business
combination  is  approved  in  a  prescribed  manner.  A  "business combination"
includes mergers, assets sales and  other transactions resulting in a  financial
benefit  to  the  interested  stockholder.  Subject  to  certain  exceptions, an
"interested  stockholder"  is  a  person  who,  together  with  affiliates   and
associates,  owns, or within the past three years  has owned, 15% or more of the
corporation's voting stock.
 
    The Restated Certificate of Incorporation  provides for the division of  the
Board  of Directors into three classes as  nearly equal in size as possible with
staggered three-year terms. See "Management." The staggered terms could have the
effect of  making  it  more difficult  for  a  third party  to  acquire,  or  of
discouraging a third party from acquiring, control of the Company.
 
    The  By-laws also provide that any action  required or permitted to be taken
by the stockholders of the  Company at an annual  meeting or special meeting  of
stockholders may only be taken if it is properly brought before such meeting and
may  not be taken  by written action in  lieu of a  meeting. The By-laws further
provide that special  meetings of  the stockholders may  only be  called by  the
President  of the Company, by the Board of Directors or by stockholders owning a
majority of  the  issued and  outstanding  capital  stock of  the  Company.  The
foregoing   provisions  could  have  the  effect  of  delaying  until  the  next
stockholders meeting stockholder actions which are  favored by the holders of  a
majority  of the outstanding voting securities  of the Company. These provisions
may also discourage another person or entity from making a tender offer for  the
Company's  Common Stock, because  such person or  entity, even if  it acquired a
majority of the outstanding voting securities  of the Company, would be able  to
take  action as  a stockholder  (such as electing  new directors  or approving a
merger) only at a duly called stockholders meeting, and not by written consent.
 
    The Restated Certificate of Incorporation limits the liability of  directors
to  the maximum extent permitted by the Delaware law. Delaware law provides that
a director of a corporation will  not be personally liable for monetary  damages
for  breach  of such  individual's  fiduciary duties  as  a director  except for
liability (i)  for  any  breach  of  such director's  duty  of  loyalty  to  the
corporation,  (ii)  for acts  or omissions  not  in good  faith or  that involve
intentional misconduct  or  a  knowing  violation of  law,  (iii)  for  unlawful
payments  of dividends or unlawful stock  repurchases or redemptions as provided
in Section  174  of  the Delaware  General  Corporation  Law, or  (iv)  for  any
transaction from which a director derives an improper personal benefit. Further,
the  Restated Certificate of Incorporation  contains provisions to indemnify the
Company's directors and  officers to  the fullest extent  permitted by  Delaware
law. The Company believes that indemnification under its Restated Certificate of
Incorporation  covers at  least negligence and  gross negligence on  the part of
 
                                       51
<PAGE>
an indemnified party and permits the Company to advance expenses incurred by  an
indemnified  party in  connection with the  defense of any  action or proceeding
arising out of such party's status  or service as a director, officer,  employee
or  other agent of the  Company upon an undertaking by  such party to repay such
advances if  it is  ultimately determined  that such  party is  not entitled  to
indemnification.  The  Company believes  that these  provisions will  assist the
Company in attracting and retaining qualified individuals to serve as directors.
 
    At present, the Company is not aware of any pending litigation or proceeding
involving any  director,  officer,  employee  or agent  of  the  Company,  where
indemnification  will be required or permitted. The  Company is not aware of any
threatened litigation  or proceeding  that  might result  in  a claim  for  such
indemnification.
 
TRANSFER AGENT AND REGISTRAR
 
   
    Registrar  and Transfer Company will act as transfer agent and registrar for
the Company's Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no market for the Common Stock of the
Company. Future  sales of  substantial amounts  of Common  Stock in  the  public
market  could adversely affect market prices prevailing from time to time. Sales
of substantial amounts of Common Stock of the Company in the public market after
the lapse of existing resale restrictions could adversely affect the  prevailing
market  price and  the ability  of the  Company to  raise equity  capital in the
future.
 
   
    Upon  completion  of  this  offering,  the  Company  will  have  outstanding
10,370,490 shares of Common Stock, assuming no exercise of currently outstanding
options.  In addition  to the  2,200,000 shares  of Common  Stock offered hereby
(assuming no exercise  of the  Underwriters' over-allotment option),  as of  the
Effective  Date, there will be 8,170,490 shares of Common Stock outstanding, all
of  which  are  "restricted  securities"  under  the  Securities  Act.   Certain
stockholders  of the Company,  holding in the  aggregate approximately 7,922,000
shares of Common Stock,  are subject to  lock-up agreements providing  generally
that  they will not  offer, sell, contract  to sell or  otherwise dispose of any
shares of Common Stock or any securities convertible or exchangeable into Common
Stock for a period  of 180 days  after the date of  this Prospectus without  the
prior  written consent of Lehman Brothers Inc.,  which may be given at any time,
without notice, with respect to  all or any portion  of such shares. Holders  of
approximately  185,000 additional shares of Common  Stock are subject to similar
restrictions contained in an Investor Rights Agreement. Taking into account  the
lock-up agreements and restrictions notwithstanding possible earlier eligibility
for resale under the provisions of Rules 144 and 701, the numbers of shares that
will be available for sale in the public market will be as follows. Beginning 90
days  after  the  Effective  Date,  approximately  63,000  shares  of restricted
securities will become  eligible for  resale in  the public  market, subject  to
compliance  with Rules 144 and 701. Beginning 180 days after the Effective Date,
approximately 5,950,000 additional shares  of restricted securities will  become
eligible  for  sale in  the  public market  upon  expiration of  certain lock-up
agreements pursuant to Rule 144 and, as of that date, approximately 5,300,000 of
such shares will  be subject  to certain  volume and  other resale  restrictions
pursuant to Rules 144 and 701.
    
 
    In  general, under Rule 144, as currently  in effect, any person (or persons
whose shares are aggregated)  who has beneficially owned  his or her  restricted
securities  (as that  term is  defined in Rule  144) for  at least  two years is
entitled to sell,  within any three-month  period, a number  of such  securities
that  does not exceed  the greater of 1%  of the then  outstanding shares of the
Company's Common  Stock (approximately  104,000  shares immediately  after  this
offering)  or the average  weekly trading volume during  the four calendar weeks
preceding the  date on  which notice  of such  sale was  filed under  Rule  144,
provided  certain  requirements concerning  availability of  public information,
manner of  sale and  notice  of sale  are  satisfied. A  person  who is  not  an
affiliate,  has not been an affiliate within  three months prior to the sale and
has beneficially owned  the restricted securities  for at least  three years  is
entitled  to sell  such shares under  Rule 144(k)  without regard to  any of the
limitations described  above. In  meeting the  two-year and  three-year  holding
periods described above, a holder of Restricted Shares may include under certain
circumstances the holding period of a prior owner.
 
    The  Securities and Exchange  Commission has proposed  certain amendments to
Rule 144 that would reduce by one  year the holding periods required for  shares
subject  to Rule 144  to become eligible  for resale in  the public market. This
proposal, if  adopted, would  increase  the number  of  shares of  Common  Stock
eligible for immediate resale following the expiration of the lock-up agreements
described  above.  No assurance  can  be given  concerning  whether or  when the
proposal will be adopted by the Securities and Exchange Commission.
 
    Any employee  or director  of or  consultant  to the  Company who  has  been
granted  options to purchase  shares or who  has purchased shares  pursuant to a
written compensatory plan  or written contract  prior to the  effective date  of
this  offering  pursuant to  Rule 701  will be  entitled to  rely on  the resale
provisions of Rule  701, which  permits non-affiliates  to sell  their Rule  701
shares  without having  to comply  with the  public information, holding-period,
volume-limitation or notice  provisions of  Rule 144 and  permits affiliates  to
sell  their Rule 701 shares  without having to comply  with the Rule 144 holding
period restrictions, in  each case  commencing 90 days  after the  date of  this
Prospectus.

    The Company intends to file, on or shortly after the date of the Prospectus,
a registration statement on Form S-8 under the Securities Act to register shares
of  Common Stock reserved for  issuance under the Predecessor  Plan and the 1996
Stock Option/Issuance Plan. Shares  issued after the effective  date of the  S-8
will  be  eligible for  resale by  non-affiliates in  the public  market without
limitation and by affiliates subject to the requirements set forth in Rule  144,
except  for  the  holding  period  limitation  of  Rule  144.  Such registration
statement will become effective immediately upon filing. As of August 31,  1996,
an aggregate of 1,238,619 shares of Common Stock are reserved for issuance under
the  Predecessor  Plan and  an additional  555,556 shares  of Common  Stock were
available for  future  grants  under  the Company's  1996  Stock  Option/  Stock
Issuance Plan.
    
 
   
    The  holders  of  approximately 8,017,000  shares  of Common  Stock  and the
holders of warrants  to purchase an  additional 138,385 shares  of Common  Stock
have the right in certain circumstances to require the Company to register their
shares  under the Securities Act  for resale to the  public. If such holders, by
exercising their demand registration rights, cause  a large number of shares  to
be  registered and sold in  the public market, such  sales could have an adverse
effect on the market price for the  Company's Common Stock. If the Company  were
required  to include  in a  Company-initiated registration  shares held  by such
holders pursuant to the  exercise of their  piggyback registration rights,  such
sales  may  have an  adverse effect  on  the Company's  ability to  raise needed
capital. See  "Description  of  Capital Stock--Registration  Rights  of  Certain
Holders."
    
 
    Prior to this offering, there has been no market for the Common Stock of the

market could adversely effect the market price of the Common Stock.

    The Underwriting Agreement provides that the obligations of the Underwriters
to purchase shares of Common Stock  are subject to certain conditions, and  that
if  any of the shares of Common Stock are purchased by the Underwriters pursuant
to the Underwriting Agreement, all shares of Common Stock agreed to be purchased
by the Underwriters pursuant to the Underwriting Agreement must be purchased.
 
    The Company  has been  advised that  the Underwriters  initially propose  to
offer  the shares of Common Stock directly  to the public at the public offering
price set forth on  the cover page  of this Prospectus  and to certain  selected
dealers  (who may include the Underwriters) at such public offering price less a
selling concession not  in excess of  $        per share.  The Underwriters  may
allow,  and such dealers may reallow, a  concession not in excess of $       per
share to certain  other Underwriters  or to  certain other  brokers or  dealers.
After  the initial public offering, the public offering price, the concession to
selected dealers and  the reallowance  to other dealers  may be  changed by  the
Underwriters.
 
    The  Company  and  the  Selling Stockholder  have  agreed  to  indemnify the
Underwriters  against  certain  liabilities,  including  liabilities  under  the
Securities  Act of  1933, as  amended, and  to contribute  to payments  that the
Underwriters may be required to make in respect thereof.
 
   
    The Selling  Stockholder  has  granted  to the  Underwriters  an  option  to
purchase  up  to an  additional 330,000  shares  of Common  Stock at  the public
offering price  less the  underwriting discounts  and commissions  shown on  the
cover  page of  this Prospectus,  solely to  cover over-allotments,  if any. See
"Principal Stockholders." Such option may be exercised at any time until 30 days
after the date of this Prospectus. To the extent that the Underwriters  exercise
such  option, each  of the  Underwriters will  be committed,  subject to certain
conditions, to  purchase  a  number  of  option  shares  proportionate  to  such
Underwriter's initial commitment.
    
 
    The  Representatives of the  Underwriters have informed  the Company and the
Selling Stockholder that  the Underwriters  do not  intend to  confirm sales  to
accounts over which they exercise discretionary authority.
 
    The Company, the Selling Stockholder, the directors and officers and certain
other  stockholders of  the Company  have agreed,  with certain  limitations and
except for  the shares  of Common  Stock to  be sold  in the  offering, not  to,
directly or indirectly, offer, sell or contract to sell, or otherwise dispose of
shares  of Common Stock of  the Company, or any  securities convertible into, or
exchangeable for, or any rights to acquire, shares of Common Stock for a  period
of  180 days after the date of this Prospectus without the prior written consent
of Lehman Brothers on behalf of the Representatives.

    Prior to  this offering,  there has  been no  public market  for the  Common
Stock. The initial public offering price will be determined by negotiation among
the Company and the Representatives of the Underwriters. Among the factors to be
considered  in determining  the initial  public offering  price, in  addition to
prevailing market  conditions, will  be  the Company's  historical  performance,
capital structure, estimates of the business potential and earnings prospects of
the  Company,  an  overall  assessment  of the  Company,  an  assessment  of the
Company's management, and the consideration of the above factors in relation  to
market valuation of companies in related businesses.
 
   
    In  February 1996, the  Company sold 2,000,000 shares  of Series F Preferred
Stock to Lehman Brothers  Holdings Inc., the parent  company of Lehman  Brothers
Inc., or approximately 10% of all shares of Series F Preferred Stock issued, for
a  purchase price of  $0.40 per share. The  Company granted certain registration
rights to Lehman Brothers Holdings Inc. in connection with that transaction.  In
addition,  a Senior  Vice President  of Lehman  Brothers Inc.  purchased 500,000
shares of  Series F  Preferred  Stock of  the Company  in  February 1996  for  a
purchase  price of  $0.40 per share,  and has been  granted certain registration
rights by the  Company. The son  of such Senior  Vice President received  22,727
shares  of Series E Preferred  Stock by gift in January  1995 from a director of
the Company and the son also purchased 2,612 shares of Series F Preferred  Stock
for  a  purchase price  of $0.40  per share  in February  1996 in  the Company's
private placement  and  has been  granted  certain registration  rights  by  the
Company.  Each nine shares  of Series E  Preferred Stock and  Series F Preferred
Stock will be converted to  one share of Common  Stock upon the consummation  of
the  offering. See "Description of Capital Stock--Registration Rights of Certain
Holders."

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Stockholders and Board of Directors
of FaxSav Incorporated:
 
    We have  audited  the accompanying  balance  sheets of  FaxSav  Incorporated
(formerly  Digitran  Corporation) as  of  December 31,  1994  and 1995,  and the
related statements of operations, stockholders' equity (deficit) and cash  flows
for  each  of the  three  years in  the period  ended  December 31,  1995. These
financial statements are  the responsibility  of the  Company's management.  Our
responsibility  is to express an opinion  on these financial statements based on
our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all material respects,  the financial position of  FaxSav Incorporated as of
December 31, 1994 and 1995, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1995 in  conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
1.  ORGANIZATION AND NATURE OF OPERATIONS:
    FaxSav Incorporated, formerly known as Digitran Corporation (the "Company"),
was  formed  in November  1989 to  engage  in the  sale of  customized facsimile
transmission services. In February 1996, the Company changed its name to  FaxSav
Incorporated.
 
    The  Company designs, develops and markets a variety of business-to-business
facsimile transmission services, including fax-to-fax, desktop to fax,  enhanced
fax and broadcast fax services. Through the use of its integrated Internet-based
and  telephony-based network and  its proprietary software,  the Company enables
its customers to send documents and images to fax machines world wide. In  early
1996,  the Company began to deploy a global Internet-based network of nodes that
enable it to bypass the long  distance carriers' networks when sending faxes  to
or  from  international areas  serviced by  these nodes.  Most of  the Company's
revenues to date have  been derived from  delivering facsimile transmissions  to
locations outside the United States from customers located throughout the United
States. The Company operates in one business segment.
 
   
    The  Company is subject to risks  common to rapidly growing technology-based
companies, including  limited operating  history, dependence  on key  personnel,
raising  equity capital, rapid technological change, competition from substitute
products and larger companies, and  the successful development and marketing  of
commercial products and services. The Company requires additional equity capital
or  financing in the near term to carry out its planned network expansion and to
fund anticipated operating  losses. In  the event the  offering contemplated  by
this  Prospectus is not  completed, without such  additional capital, management
believes that the Company's current sources  of liquidity are sufficient for  it
to  continue operations  through September 30,  1997 after  limiting its network
expansion and significantly reducing operating expenses to a level that  enables
the  Company to continue serving primarily  existing customers. The reduction in
operating expenses would include halting research and development activities and
substantially reducing sales and marketing expenditures.
    
 
    Fax boards used in the  Company's telecommunication network are supplied  by
one vendor on a non-exclusive basis. Other components of the Company's operating
network  are supplied by  a limited number  of vendors, also  on a non-exclusive
basis. Management believes that other  suppliers could be identified to  provide
this  equipment  at  a  competitive  price if  these  suppliers  were  unable or
unwilling to provide such equipment.
 
    Operation of the  Company's network  to date  has been  dependent upon  long
distance  telecommunication companies transmitting  information for the Company.
The Company has typically utilized only  a limited number of these providers  to
generate  volume discounts.  The Company's  business strategy  is also dependent
upon providing  this  service at  the  lowest  possible cost  which  is  greatly
affected  by the cost of long distance transmission service. Management believes
that its long-distance transmissions could be made at competitive rates with any
number of companies providing long distance service.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    A.  REVENUE RECOGNITION AND COST OF SERVICE:
 
    The Company recognizes  revenue as  services are provided  to customers  and
records  the related cost  of service as  incurred. Cost of  service consists of
local access charges, leased  network backbone circuit  costs and long  distance
domestic and international termination charges.
 
    B.  ESTIMATES:
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions    that    affect    the   reported    amounts    of    assets   and

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
liabilities and disclosure of contingent assets  and liabilities at the date  of
the  financial  statements and  the reported  amounts  of revenues  and expenses
during the reporting period. Actual results could differ from those estimates.
 
    Significant estimates  made  by management  and  included in  the  financial
statements are the allowance for bad debts, valuation allowance for deferred tax
assets, provision for FAXSAV CONNECTORS and accrual for legal defense.
 
    C.  INTERIM FINANCIAL INFORMATION (UNAUDITED):
 
   
    The  financial statements as of  June 30, 1996 and  for the six months ended
June 30,  1995 and  1996 are  unaudited. In  the opinion  of management  of  the
Company,  such unaudited financial statements include all adjustments necessary,
which include only normal recurring items, to present fairly the information set
forth therein. Results for the interim periods are not necessarily indicative of
the results for any other interim period or the full year.
    
 
    D.  UNAUDITED PRO FORMA INFORMATION:
 
    All of  the Company's  convertible  preferred stock  outstanding as  of  the
closing  date of an initial public offering will be converted into shares of the
Company's common stock at the consent of  the holders of the preferred stock.  A
pro  forma balance sheet as of June 30, 1996 would reflect the conversion of all
outstanding preferred stock  into 7,790,489 (unaudited)  shares of common  stock
with  a par value of $0.01, assuming a  reverse stock split for common shares of
one-for-nine shares.
 
    E.  NET LOSS PER COMMON AND EQUIVALENT SHARE:
 
    Net loss per  common and  equivalent share  is computed  using the  weighted
average  number of shares of common  stock outstanding. Common equivalent shares
from stock options, warrants and preferred  stock (except as required by SAB  83
referred  to below)  are excluded  from the computation  as the  effect is anti-
dilutive. Historical earnings per share data do not assume the conversion of the
preferred stock into common stock described above which would materially  change
the  Company's capitalization. Fully diluted loss  per share is not presented as
it would not materially differ from the primary loss per share data.
 
    F.  PRO FORMA NET LOSS PER COMMON AND EQUIVALENT SHARE:
 
    Pro forma net loss per common and equivalent share is based on the  weighted
average number of shares outstanding during the periods presented, including the
effect of a reverse stock split for common shares of one-for-nine shares to take
effect prior to the effective date of this registration statement and conversion
of  all outstanding preferred  stock into 7,790,489 shares  of common stock (see
Note 14). Pursuant to  the Securities and  Exchange Commission Staff  Accounting
Bulletin  No. 83 ("SAB 83"), all shares,  options and warrants issued during the
twelve months immediately preceding the initial public offering were treated  as
if  they had been outstanding  for all periods, using  the treasury stock method
and assuming a per share price  of $11.00, the proposed initial public  offering
price.  Common stock equivalents (i.e.,  convertible preferred stock and certain
stock options and  warrants) issued in  earlier periods have  not been  included
since the effect would be antidilutive.
 
    G.  PROPERTY AND EQUIPMENT:
 
    Property  and equipment are stated at  cost, net of accumulated depreciation
and amortization. Depreciation of furniture  and equipment, except enhanced  fax
equipment,  is calculated  using the  straight-line method  over their estimated
useful lives of five years. Enhanced fax equipment is included in equipment  and
is  depreciated over its estimated life of 30 months. Leasehold improvements are
amortized using the straight-line  method over the lesser  of the lease term  or
the estimated useful life of the related asset. Repairs

and  maintenance costs are expensed as  incurred; major renewals and betterments
are capitalized. When  assets are sold  or otherwise disposed  of, the cost  and
related  accumulated depreciation are removed from  the accounts and any gain or
loss on the disposition is reflected in current operations.
 
    H.  CASH FLOWS:
 
    For  purposes  of  the  statement  of  cash  flows,  the  Company  considers
short-term  investments with a maturity  at date of purchase  of three months or
less to be cash equivalents.
 
    I.  INCOME TAXES:
 
    The Company  accounts  for income  taxes  in accordance  with  Statement  of
Financial  Accounting  Standards No.  109, "ACCOUNTING  FOR INCOME  TAXES". This
statement provides  an asset  and  liability approach  for deferred  taxes  that
requires the recognition of deferred tax assets and liabilities for the expected
future  tax consequences  of events that  have been recognized  in the Company's
financial statements or tax returns.
 
    J.  CONCENTRATION OF CREDIT RISK:
 
    Statement  of  Financial  Accounting  Standards  No.  105,  "DISCLOSURE   OF
INFORMATION   ABOUT  FINANCIAL  INSTRUMENTS   WITH  OFF-BALANCE-SHEET  RISK  AND
FINANCIAL INSTRUMENTS WITH CONCENTRATION OF CREDIT RISK," requires disclosure of
any significant  off-balance-sheet  and credit  risk  concentrations.  Financial
instruments  that potentially  subject the  Company to  concentrations of credit
risk consist primarily of cash,  cash equivalents and accounts receivable.  From
time  to time, the  Company had concentrations  of cash in  several banks in the
form of demand  deposits and money  market accounts. The  Company believes  that
concentrations  of credit  risk with  respect to  trade accounts  receivable are
limited due to the  large number of entities  comprising the Company's  customer
base.
 
    K.  FINANCIAL INSTRUMENTS:
 
    The  estimated  fair value  of  the Company's  financial  instruments, which
include cash, cash equivalents,  accounts receivable, obligations under  capital
lease  and amounts outstanding under line of credit, approximates their carrying
value.
 
    The  fair  value   of  cash,  cash   equivalents  and  accounts   receivable
approximates  their carrying value because their maturity is generally less than
one year in  duration. The  fair value of  obligations under  capital lease  and
amounts  outstanding under  the line  of credit  was determined  using valuation
techniques that considered cash flow discounted at current rates.
 
    L.  IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS:
 
    For the year ended  December 31, 1996, the  Company will adopt Statement  of
Financial  Accounting  Standards  No.  121, "ACCOUNTING  FOR  THE  IMPAIRMENT OF
LONG-LIVED ASSETS AND FOR  LONG-LIVED ASSETS TO BE  DISPOSED OF". This  standard
establishes  accounting  standards  for  the  impairment  of  long-lived assets,
certain identifiable intangibles,  and goodwill  related to those  assets to  be
held  and used for long-lived assets  and certain identifiable intangibles to be
disposed of.
 
   
    The Company will adopt the  disclosure provisions of Statement of  Financial
Accounting  Standards No. 123, "ACCOUNTING FOR STOCK BASED COMPENSATION" for the
year ending December 31, 1996. Such provisions of this standard will require the
Company to disclose the fair value of options granted in 1995 and thereafter and
the pro forma effects on net loss and  net loss per share for the fair value  of
options granted. There will be no impact on the Company's results of operations,
financial position or liquidity.
    
 
    Management  does  not  expect the  adoption  of  these standards  to  have a
material effect on the Company's financial position or results of operations.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    M.  LEGAL DEFENSE:
 
    The Company accrues the  estimated future cost  of defending itself  against
lawsuits  or other claims  when management has  determined, in consultation with
its legal counsel,  that these  matters are  probable of  assertion against  the
Company.
 
    N.  UNRECOVERABLE EQUIPMENT:
 
    The  Company provides for the estimated book value of FAXSAV CONNECTORS held
by former  or  inactive  customers  that are  considered  unrecoverable.  It  is
reasonably   possible  that  the  Company's  estimate   of  the  book  value  of
unrecoverable equipment would change in the near future due to increases in  the
number of former or inactive customers.
 
3.  PROPERTY AND EQUIPMENT:
    Property and equipment, net is comprised of the following:

7.  CAPITAL STOCK AND WARRANTS (SEE ALSO NOTES 13 AND 14): (CONTINUED)
    WARRANTS
 
    The Company initially granted warrants to purchase 78,200 shares of Series B
Preferred Stock to a firm that had provided the Company with equipment  pursuant
to a lease agreement. These warrants expire ten years from the date of grant and
have  an exercise  price of $1.00  per share.  On October 28,  1993, the Company
granted additional warrants, which expire ten  years from the date of grant,  to
this  firm to purchase 87,570 shares of Series  D Preferred Shares at a price of
$0.1733 per share  in consideration of  the deferral of  all payments under  the
lease agreement in excess of $5,000 per month through January 31, 1994.
 
    On  July 8,  1993, the  Company agreed to  grant warrants  to purchase 5,556
shares of common stock to another firm providing equipment to the Company  under
a Master Lease Agreement. The exercise price is $5.40 per share and the warrants
expire  ten years from  the date of grant.  On May 5,  1994, the Company granted
additional warrants, which expire ten years from the date of grant, to  purchase
9,889  shares of common stock at $1.80 per share to this firm in connection with
an increase in the equipment covered by the Master Lease Agreement.
 
    During  October  and  November  1993,  warrants  were  issued  to  preferred
stockholders to acquire 321,086 shares of Series C Preferred Stock in connection
with  the issuance  of promissory  notes for cash  by the  Company. The exercise
price is $0.60  per share and  the warrants expire  ten years from  the date  of
grant.
 
    On  July 7, 1995, the Company granted  warrants to purchase 28,889 shares of
common stock to a bank  in connection with the  issuance of the working  capital
line  of credit. The exercise  price is $1.98 per  share and the warrants expire
five years from the date of grant.
 
   
    The number  and  purchase  price  of  the shares  may  be  adjusted  by  the
occurrence  of certain  events, as defined  in the warrant  agreements. Upon the
conversion of the  preferred stock into  common stock as  described in Note  14,
each  warrant to  acquire shares  of preferred  stock will  be adjusted  for the
conversion of preferred stock into common  stock. Management of the Company  has
determined  that the value of  the warrants issued in  connection with the above
referenced leasing  arrangements  and  credit  agreements  was  DE  MINIMIS  (an
aggregate  value of approximately $30,000 for  all warrants granted between 1993
and 1995) when the exercise  price of the warrant  is considered in relation  to
the  estimated fair value of the Company's common stock and preferred stock and,
accordingly, no value has been ascribed to such warrants. Such value would  have
been  recorded as a deferred  financing cost and amortized  over the life of the
underlying borrowing facility.
    
 
8.  STOCK OPTIONS (SEE ALSO NOTE 14):
   
    The Company has  a stock  option plan which,  as amended,  authorizes up  to
12,000,000 shares of common stock to be issued. Under the stock option plan, the
Company  may grant  incentive stock options  or nonqualified  stock options. The
option exercise price  of stock options  may not be  less than 85%  of the  fair
value of a share of common stock on the date of the option grant. The excess, if
any, of the fair value of underlying common stock over the exercise price of the
option is charged to compensation expense over the vesting period of the option.
The  shares  issuable upon  the  exercise of  incentive  stock options,  and any
nonqualified options granted to employees, generally vest 20% upon completion by
the optionee of one year of service and the remaining 80% over 48 equal  monthly
installments thereafter based on continued service. The shares issuable upon the
exercise  of nonqualified options except for those granted to employees as noted
above, vest over two years from the date of grant.
    
 
    Effective October 1, 1993,  the Company was authorized  to grant options  to
purchase  up to 411,111 shares of common  stock to certain employees under a key
employee retention program. On October 1,  1993, the Company granted options  to
purchase  139,778  shares  of  common  stock at  $0.90  per  share  to employees

who elected to participate in the program. Coincident with the January 1994 sale
of stock,  employees  in  the  program  were  granted  options  to  purchase  an
additional 135,667 shares of common stock at $0.90 per share. The aforementioned
options  vested on October 31,  1994 unless the employee  was no longer with the
Company. The balance  of available  shares (172,060  as of  December 31,  1994),
including  forfeitures, were to be granted upon a sale or merger of the Company.
In March  1995, the  Company  granted the  remaining  options available  to  the
eligible employees and granted other options to certain key executives.
 
    Stock option transactions under the plan are as follows:

9.  LINE OF CREDIT:
    In July 1995, the Company entered into a Credit Agreement (Agreement) with a
bank  (the Bank). As of December 31, 1995, this Agreement, as amended, comprises
a $1,000,000 working capital line of  credit which includes a $500,000  sublimit
for  the  issuance of  letters  of credit.  The  Agreement provides  for certain
restrictions and covenants, including the payment of dividends on the  Company's
common stock and incurring additional indebtedness. As of December 31, 1995, the
Company   was  in  default  of   certain  financial  covenants,  which  included
requirements with respect to liquidity,  net worth, leverage and  profitability;
however,  the Bank waived these defaults.  In connection with the Agreement, the
Company issued warrants (see Note 8) to the Bank.

9.  LINE OF CREDIT: (CONTINUED)
   
    In April 1996, the Company accepted  a revised commitment which renewed  the
$1,000,000 working capital line of credit and extended a $750,000 equipment line
of  credit  (collectively referred  to  as line  of  credit). Under  the revised
Agreement, the working capital line of credit expires in April 1997. Any amounts
borrowed under the equipment line of credit are payable in monthly  installments
over  a  three-year period  commencing in  October  1996. The  revised Agreement
contains the same basic covenants as discussed  above. As of June 30, 1996,  the
Company  was in default of certain  financial covenants contained in the revised
Agreement; however, the Bank waived these defaults and revised the covenants for
the period July 31, 1996 until  December 31, 1996. The revised agreement  limits
the  total amount outstanding under  the line of credit  to $1 million until the
Company raises additional equity. In addition, the Credit Facility, as  amended,
contains  a covenant  that the  anticipated public  offering of  securities must
occur or the Company must raise an additional $3 million in equity on or  before
October 15, 1996.
    
 
    At  December 31, 1995 and June 30, 1996, $1,000,000 and $500,000 (unaudited)
were outstanding under  the working capital  line of credit.  At June 30,  1996,
$165,796  (unaudited) was  outstanding under the  equipment line  of credit. The
amounts outstanding under the facilities approximates its fair value due to  the
short-term  nature of the obligations. Interest on  advances, if any, are at the
Bank's prime rate plus an applicable margin, as defined in the credit agreement,
which resulted in a borrowing rate of  10.5% and 8.75% at December 31, 1995  and
June 30, 1996, respectively.
 
10. INCOME TAXES:
 
    Inasmuch  as the Company  continues to incur  operating losses and currently
pays no  income  taxes,  no provision  or  benefit  for income  taxes  has  been
recorded.
 
    The  income tax benefit at  the United States federal  statutory rate on the
Company's operating loss, for all periods  presented, has been eliminated by  an
increase in the valuation allowance for deferred tax assets and operating losses
not recognized.
 
    Through  December 31,  1995, the  Company has  generated net  operating loss
carryforwards for income tax purposes of approximately $16,104,000, which expire
through 2010.  Net  operating  loss  carryforwards are  subject  to  review  and
possible  adjustment by the Internal  Revenue Service and may  be limited in the
event of certain cumulative  changes in the  ownership interests of  significant
stockholders  over a three-year period in excess of 50%. The Company believes it
has experienced changes in ownership in excess of 50% and that these changes  in
ownership  will affect the  Company's ability to utilize  its net operating loss
carryforwards to offset future taxable income, if any.
 
    The components of the Company's deferred tax asset are as follows:

                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
10. INCOME TAXES: (CONTINUED)
    In evaluating the realizability of these deferred tax assets, management has
considered the  market  in which  the  Company operates,  the  operating  losses
incurred  to  date and  the  operating losses  anticipated  for the  future, and
believes that  given  the  significance  of  this  evidence,  a  full  valuation
allowance  against its deferred tax  assets is required as  of December 31, 1994
and 1995.
 
11. 401(K) RETIREMENT PLAN:
    Effective January 1, 1993, the Company  offered a 401(k) retirement plan  to
its  employees.  Employees  who  are at  least  21  years of  age  may  become a
participant after three months of service. Contributions to the Plan are made on
a pre-tax  basis  through payroll  deductions.  The  Company did  not  make  any
matching  contributions to  the Plan during  the years ended  December 31, 1994,
1995 and the six months ended June 30, 1996.
 
12. CONTINGENCIES:
    The Company is involved in various disputes, claims or legal proceedings and
may be  included  in  future  actions  including  infringement  on  intellectual
property  rights, related to  its normal course  of business. In  the opinion of
management, all such matters are without  merit or involve amounts, if  disposed
of  unfavorably, which would not have a material adverse effect on the financial
position or results of operations of the Company.
 
13. TELSTRA AGREEMENTS:
    On January 18,  1994, the  Company and Telstra  Incorporated ("Telstra"),  a
wholly-owned  subsidiary  of  Telstra  Holding  -Pty  Limited,  entered  into  a
Preferred Stock Purchase Agreement which  provided for, among other things:  (a)
the  sale and issuance  of 17,311,021 shares  of Series D  Preferred Stock for a
purchase price of $3,000,000 ($.1733 per share); (b) the grant of an option,  on
a  one-time basis between January 1, 1996 and December 31, 1996, to acquire 100%
of the fully diluted shares of the Company's outstanding common stock not  owned
by  Telstra;  (c)  Telstra's designation  of  two  of the  five  numbers  of the
Company's Board of Directors, whose size may not be increased without  Telstra's
approval;  (d) Telstra's  prior approval  on certain  business decisions  of the
Company, including business  plans, annual budgets,  issuance of securities  and
certain  indebtedness; (e) an additional  equity investment through the purchase
of Series  D Preferred  Stock  at $0.1733  per share  of  up to  $1,250,000,  if
required  by  the Company,  to  be made  by  the current  Preferred Stockholders
(exclusive of Telstra) on a pro rata  basis no later than January 31, 1995;  and
(f)  under the  terms of  an amended  stockholders agreement,  the holders  of a
majority of the Registerable Securities, as  defined, may request, after May  1,
1994, that the Company file a registration statement under the Securities Act of
1933.
 
    The  proceeds  from the  issuance of  the  shares to  Telstra were  used for
working capital  and  capital expenditures  for  the purpose  of  sustaining  or
expanding  the Company's  market share.  Costs incurred  in connection  with the
issuance of the Series D Preferred Stock amounted to approximately $134,000.
 
    On February  1,  1994,  the  Company and  Telstra  entered  into  a  Service
Agreement  whereby  the Company  will  provide management,  technical  and other
services in support of Telstra's "WorldFax" service in the U.S. for a period  of
18  months. In consideration for these  services, Telstra paid the Company total
consideration of $750,000. The  Company received $309,375  and $440,625 in  1994
and  1995, respectively, in accordance with the Service Agreement which has been
included  as  other  revenue  to  offset  operating  expenses  incurred  in  the
accompanying statements of operations.
 
    On  October 31,  1994, the  Preferred Stock  Purchase Agreement  referred to
above was amended in  connection with the Company's  intent to raise  additional
equity  funds.  The  amended agreement  provided  for, among  other  things: (a)
termination of Telstra's option to acquire  100% of the fully diluted shares  of
the

Company's  common stock; (b) an  increase in the size  of the Company's Board of
Directors to six members upon the  closing of additional equity financing of  $2
million;  (c)  Telstra to  designate one  of  the five  original members  of the
Company's Board of  Directors if  Telstra's ownership  were to  fall below  20%,
subject  to adjustments  with the  approval of Telstra;  and (d)  if the Company
completes an initial public offering of its  common stock, it will no longer  be
subject  to  certain  covenants and  agreements  with Telstra  and  Telstra will
relinquish approval of the Company's business decisions.
 
    In December  1995, the  Company  and Telstra  entered  into a  Stock  Option
Agreement  which provided for, among other things,  an option for the Company to
purchase from  Telstra, 8,655,510  shares  of Series  D  Preferred Stock  at  an
exercise  price of $0.25  per share. Upon  exercise of the  option Telstra could
designate one of the six members of  the Company's Board of Directors until  the
earlier  of (a) Telstra's  equity ownership in  the Company falls  below 5% on a
fully diluted basis or  (b) an initial public  offering of the Company's  common
stock, at which time they will no longer have Board representation.
 
    In  March  1996,  the  Company exercised  its  option  to  acquire 8,655,510
(unaudited) shares of Series D Preferred Stock at an aggregate purchase price of
$2,163,878 (unaudited).
 
14. OTHER EVENTS (UNAUDITED):
    In connection  with  the  anticipated public  offering  of  securities,  the
Company  is expected  to file  an amendment  to its  Fifth Amended  and Restated
Certificate of  Incorporation which  will effect  a one-for-nine  reverse  stock
split  at a par value of $0.01 and change the authorized number of common shares
to 40,000,000 prior to  the effective date of  this Registration Statement.  All
share  and per share amounts in the financial statements have been retroactively
restated to reflect the reverse stock split.
 
    The Company is also expected to file immediately prior to the closing of the
offering its Sixth Amended and Restated Certificate of Incorporation which  will
change  the  authorized number  of preferred  stock.  All outstanding  shares of
preferred stock will convert at the consent of the holders into an aggregate  of
7,790,489  shares  of  common stock.  The  effect  of this  conversion  has been
presented in  the accompanying  balance sheets  and statements  of  stockholders
equity (deficit) on a pro forma basis as of June 30, 1996.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the  Delaware General Corporation Law  authorizes a court  to
award  or  a  corporation's  Board  of  Directors  to  grant  indemnification to
directors  and   officers   in  terms   sufficiently   broad  to   permit   such
indemnification   under   certain  circumstances   for   liabilities  (including
reimbursement for expenses incurred) arising  under the Securities Act of  1933,
as  amended  (the  "Act"). Article  IX  of  the Registrant's  Sixth  Amended and
Restated Certificate  of  Incorporation  provides  for  indemnification  of  its
directors  and officers and  permissible indemnification of  employees and other
agents to the maximum extent permitted by the Delaware General Corporation  Law.
Reference  is also made to Section 10 of the Underwriting Agreement contained in
Exhibit 1.1 hereto,  which sets  forth certain  indemnification provisions.  The
Registrant plans to obtain liability insurance for its officers and directors.

ITEM 17.  UNDERTAKINGS
 
    The  undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing  specified in  the Underwriting Agreement,  certificates in  such
denominations  and registered in  such names as required  by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as  indemnification for  liabilities arising  under the  Act may  be
permitted  to  directors, officers  and  controlling persons  of  the Registrant
pursuant  to  the   Delaware  General  Corporation   Law,  the  Certificate   of
Incorporation  of the Registrant, the  Underwriting Agreement, 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
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 hereunder, the Registrant will,
unless in the  opinion of  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 Act  and
will be governed by the final adjudication of such issue.
 
    The undersigned Registrant hereby undertakes:
 
    (1)  That  for purposes  of  determining any  liability  under the  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 Act shall be deemed to  be part of this Registration Statement as
of the time it was declared effective.
 
    (2) That for the  purpose of determining any  liability under the Act,  each
post-effective  amendment that contains a form  of Prospectus 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.

     THIRD: The text of the Sixth Amended and Restated Certificate of
Incorporation, as hereby restated and amended hereby, shall read in its entirety
as follows:

                                    ARTICLE I

     The name of this corporation is: FaxSav Incorporated.

                                   ARTICLE II

     The address of the registered office of the corporation in the State of
Delaware is 1209 Orange Street, in The City of Wilmington, County of New Castle.
The name of its registered agent at such address is The Corporation Trust
Company.

                                   ARTICLE III

     The purpose of this corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law.

                                   ARTICLE IV

     A. Classes of Stock. This corporation is authorized to issue two classes of
stock to be designated, respectively, "Common Stock" and "Preferred Stock." The
total number of shares which the corporation is authorized to issue is Forty One
million (41,000,000) shares. Forty million (40,000,000) shares, par value $0.01
per share, shall be Common Stock and One million (1,000,000) shares, par value
$0.01 per share, shall be Preferred Stock. The number of authorized shares of
Common Stock may be increased or decreased (but not below the number of shares
thereof then outstanding) by the affirmative vote of the holders of a majority
of the stock of the corporation entitled to vote, irrespective of the provisions
of Section 242(b)(2) of the General Corporation Law of Delaware.

     B. Common Stock.

          (1) General. All shares of Common Stock will be identical and will
     entitle the holders thereof to the same rights, powers and privileges. The
     rights, powers and privileges of the holders of the Common Stock are
     subject to and qualified by the rights of holders of the Preferred Stock.

          (2) Dividends. Dividends may be declared and paid on the Common Stock
     from funds lawfully available therefor as and when determined by the Board
     of Directors and subject to any preferential dividend rights of any then
     outstanding Preferred Stock.

          (3) Dissolution, Liquidation or Winding Up. In the event of any
     dissolution, liquidation or winding up of the affairs of the corporation,
     whether voluntary or involuntary, each issued and outstanding share of
     Common Stock shall entitle the holder thereof to receive an equal portion
     of the net assets of the corporation available for distribution to the
     holders of Common Stock, subject to any preferential rights of any then
     outstanding Preferred Stock.

                                        2

<PAGE>




          (4) Voting Rights. Except as otherwise required by law or this Sixth
     Amended and Restated Certificate of Incorporation, each holder of Common
     Stock shall have one vote in respect of each share of stock held of record
     by such holder on the books of the corporation for the election of
     directors and on all matters submitted to a vote of stockholders of the
     corporation. Except as otherwise required by law or provided herein,
     holders of Common Stock shall vote together as a single class, subject to
     any special or preferential voting rights of any then outstanding Preferred
     Stock. There shall be no cumulative voting.

          (5) Redemption. The Common Stock is not redeemable.

     C. Preferred Stock. The Board of Directors is authorized, subject to
limitations prescribed by law and the provisions of ARTICLE IV, to provide for
the issuance of the shares of Preferred Stock in series, and by filing a
certificate pursuant to the applicable law of the State of Delaware, to
establish from time to time the number of shares to be included in each such
series, and to fix the designation, powers, preferences, and rights of the
shares of each such series and the qualifications, limitations or restrictions
thereof.

     The authority of the Board with respect to each series shall include, but
not be limited to, determination of the following:

          (1) The number of shares constituting that series and the distinctive
     designation of that series;

          (2) The dividend rate on the shares of that series, whether dividends
     shall be cumulative, and, if so, from which date or dates, and the relative
     rights of priority, if any, of payment of dividends on shares of that
     series;

          (3) Whether that series shall have voting rights, in addition to the
     voting rights provided by law, and, if so, the terms of such voting rights;

          (4) Whether that series shall have conversion privileges, and, if so,
     the terms and conditions of such conversion, including provision for
     adjustment of the conversion rate in such events as the Board of Directors
     shall determine;

          (5) Whether or not the shares of that series shall be redeemable, and,
     if so, the terms and conditions of such redemption, including the date or
     dates upon or after which they shall be redeemable, and the amount per
     share payable in case of redemption, which amount may vary under different
     conditions and at different redemption dates;

          (6) Whether that series shall have a sinking fund for the redemption
     or purchase of shares of that series, and, if so, the terms and amount of
     such sinking fund;

          (7) The rights of the shares of that series in the event of voluntary
     or involuntary liquidation, dissolution or winding up of the corporation,
     and the relative rights or priority, if any, of payment of shares of that
     series; and


                                        3

<PAGE>



          (8) Any other relative rights, preferences and limitations of that
     series.

     Dividends on outstanding shares of Preferred Stock shall be paid or
declared and set apart for payment before any dividends shall be paid or
declared and set apart for payment on the Common Stock with respect to the same
dividend period.

     If upon any voluntary or involuntary liquidation, dissolution or winding up
of the corporation, the assets available for distribution to holders of shares
of Preferred Stock of all series shall be insufficient to pay such holders the
full preferential amount to which they are entitled, then such assets shall be
distributed ratably among the shares of all series of Preferred Stock in
accordance with the respective preferential amounts (including unpaid cumulative
dividends, if any) payable with respect thereto.

                                    ARTICLE V

     In furtherance of and not in limitation of powers conferred by statute, it
is further provided:

          A. Election of directors need not be by written ballot.

          B. The Board of Directors is expressly authorized to adopt, amend or
     repeal the By-Laws of the corporation.

                                   ARTICLE VI

     The number of directors of the corporation shall be fixed from time to time
by a By-law or amendment thereof duly adopted by the Board of Directors or by
the stockholders.

     The Board of Directors shall be and is divided into three classes: Class I,
Class II and Class III, which shall be as nearly equal in number as possible.
Each director shall serve for a term ending on the date of the third annual
meeting of stockholders following the annual meeting at which the director was
elected; provided, however, that each initial director in Class I shall hold
office until the annual meeting of stockholders in 1997; each initial director
in Class II shall hold office until the annual meeting of stockholders in 1998;
and each initial director in Class III shall hold office until the annual
meeting of stockholders in 1999. Notwithstanding the foregoing provisions of
this Article, each director shall serve until his successor is duly elected and
qualified or until his death, resignation or removal.

     In the event of any increase or decrease in the authorized number of
directors, (1) each director then serving as such shall nevertheless continue as
a director of the class of which he is a member until the expiration of his
current term, or his earlier resignation, removal from office or death, and (2)
the newly created or eliminated directorship resulting from such increase or
decrease shall be apportioned by the Board of Directors among the three classes
of directors so as to maintain such classes as nearly equal as possible.

<PAGE>



                                   ARTICLE VII

     Meetings of stockholders may be held within or without the State of
Delaware, as the By-laws may provide. The books of the corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the By-laws of the corporation.

     The Stockholders of the corporation may not take any action by written
consent in lieu of a meeting.

                                  ARTICLE VIII

     Except to the extent that the General Corporation Law of Delaware prohibits
the elimination or limitation of liability of directors for breaches of
fiduciary duty, no director of the corporation shall be personally liable to the
corporation or its stockholders for monetary damages for any breach of fiduciary
duty as a director, notwithstanding any provision of law imposing such
liability. If the General Corporation Law is amended after approval by the
stockholders of this Article to authorize corporate action further eliminating
or limiting the personal liability of directors, then the liability of a
director of the corporation shall be eliminated or limited to the fullest extent
permitted by the General Corporation Law of the State of Delaware, as so
amended. No amendment to or repeal of this provision shall apply to or have any
effect on the liability or alleged liability of any director of the corporation
for or with respect to any acts or omissions of such director occurring prior to
such amendment.

                                   ARTICLE IX

     The corporation may, to the fullest extent permitted by Section 145 of the
General Corporation Law of Delaware, as amended from time to time, indemnify
each person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was, or has agreed to become, a director or officer of the corporation, or is or
was serving, or has agreed to serve, at the request of the corporation, as a
director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons being referred to hereafter as an
"Indemnitee"), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him or
on his behalf in connection with such action, suit or proceeding and any appeal
therefrom.

     Indemnification may include payment by the corporation of expenses in
defending an action or proceeding in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by the Indemnitee to repay
such payment if it is ultimately determined that such person is not entitled to
indemnification under this Article,

                                        5

<PAGE>



which undertaking may be accepted without reference to the financial ability of
such person to make such repayment.

     The corporation shall not indemnify any such person seeking indemnification
in connection with a proceeding (or part thereof) initiated by such person
unless the initiation thereof was approved by the Board of Directors of the
corporation.

     The indemnification rights provided in this Article (i) shall not be deemed
exclusive of any other rights to which Indemnitees may be entitled under any
law, agreement or vote of stockholders or disinterested directors or otherwise,
and (ii) shall inure to the benefit of the heirs, executors and administrators
of such persons. The corporation may, to the extent authorized from time to time
by its Board of Directors, grant indemnification rights to other employees or
agents of the corporation or other persons serving the corporation and such
rights may be equivalent to, or greater or less than, those set forth in this
Article.

                                    ARTICLE X

     The corporation reserves the right to amend, alter, change or repeal any
provision contained in this Sixth Amended and Restated Certificate of
Incorporation, in the manner now or hereafter prescribed by statute and this
Sixth Amended and Restated Certificate of Incorporation, and all rights
conferred upon stockholders herein are granted subject to this reservation.

                                   ARTICLE XI

     Whenever a compromise or arrangement is proposed between this corporation
and its creditors or any class of them and/or between this corporation and its
stockholders or any class of them, any court of equitable jurisdiction within
the State of Delaware may, on the application in a summary way of this
corporation or of any creditor or stockholder thereof, or on the application of
any receiver or receivers appointed for this corporation under the provisions of
section 291 of Title 8 of the Delaware Code or on the application of trustees in
dissolution or of any receiver or receivers appointed for this corporation under
the provisions of section 279 of Title 8 of the Delaware Code order a meeting of
the creditors or class of creditors, and/or of the stockholders or class of
stockholders of this corporation, as the case may be, to be summoned in such
manner as the said court directs. If a majority in number representing
three-fourths in value of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of this corporation, as the case may be,
agree to any compromise or arrangement and to any reorganization of this
corporation as consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of this corporation, as the case may be, and also on this
corporation.

                               FAXSAV INCORPORATED
                      1996 STOCK OPTION/STOCK ISSUANCE PLAN


                                   ARTICLE ONE

                               GENERAL PROVISIONS


  I. PURPOSE OF THE PLAN

     This 1996 Stock Option/Stock Issuance Plan is intended to promote the
interests of FaxSav Incorporated, a Delaware corporation, by providing eligible
persons with the opportunity to acquire a proprietary interest, or otherwise
increase their proprietary interest, in the Corporation as an incentive for them
to remain in the service of the Corporation.

     Capitalized terms shall have the meanings assigned to such terms in the
attached Appendix.

 II. STRUCTURE OF THE PLAN

     A. The Plan shall be divided into three separate equity programs:

          (i) the Discretionary Option Grant Program under which eligible
     persons may, at the discretion of the Plan Administrator, be granted
     options to purchase shares of Common Stock,

          (ii) the Stock Issuance Program under which eligible persons may, at
     the discretion of the Plan Administrator, be issued shares of Common Stock
     directly, either through the immediate purchase of such shares or as a
     bonus for services rendered the Corporation (or any Parent or Subsidiary),
     and

          (iii) the Automatic Option Grant Program under which Eligible
     Directors shall automatically receive option grants at periodic intervals
     to purchase shares of Common Stock.

     B. The provisions of Articles One and Five shall apply to all equity
programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

III. ADMINISTRATION OF THE PLAN



<PAGE>



     A. Prior to the Section 12(g) Registration Date, the Discretionary Option
Grant and Stock Issuance Programs shall be administered by the Board. Beginning
with the Section 12(g) Registration Date, the Primary Committee shall have sole
and exclusive authority to administer the Discretionary Option Grant and Stock
Issuance Programs with respect to Section 16 Insiders.

     B. Administration of the Discretionary Option Grant and Stock Issuance
Programs with respect to all other persons eligible to participate in those
programs may, at the Board's discretion, be vested in the Primary Committee or a
Secondary Committee, or the Board may retain the power to administer those
programs with respect to all such persons. The members of the Secondary
Committee may be Board members who are Employees eligible to receive
discretionary option grants or direct stock issuances under the Plan or any
other stock option, stock appreciation, stock bonus or other stock plan of the
Corporation (or any Parent or Subsidiary).

     C. Members of the Primary Committee or any Secondary Committee shall serve
for such period of time as the Board may determine and may be removed by the
Board at any time. The Board may also at any time terminate the functions of any
Secondary Committee and reassume all powers and authority previously delegated
to such committee.

     D. Each Plan Administrator shall, within the scope of its administrative
functions under the Plan, have full power and authority to establish such rules
and regulations as it may deem appropriate for proper administration of the
Discretionary Option Grant and Stock Issuance Programs and to make such
determinations under, and issue such interpretations of, the provisions of such
programs and any outstanding options or stock issuances thereunder as it may
deem necessary or advisable. Decisions of the Plan Administrator within the
scope of its administrative functions under the Plan shall be final and binding
on all parties who have an interest in the Discretionary Option Grant or Stock
Issuance Program under its jurisdiction or any option or stock issuance
thereunder.

     E. Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

     F. Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to option
grants made thereunder.

          (iii) consultants and other independent advisors who provide services
     to the Corporation (or any Parent or Subsidiary).

     B. Each Plan Administrator shall, within the scope of its administrative
jurisdiction under the Plan, have full authority (subject to the provisions of
the Plan) to determine, (i) with respect to the option grants under the
Discretionary Option Grant Program, which eligible persons are to receive option
grants, the time or times when such option grants are to be made, the number of
shares to be covered by each such grant, the status of the granted option as
either an Incentive Option or a Non-Statutory Option, the time or times at which
each option is to become exercisable, the vesting schedule (if any) applicable
to the option shares and the maximum term for which the option is to remain
outstanding and (ii) with respect to stock issuances under the Stock Issuance
Program, which eligible persons are to receive stock issuances, the time or
times when such issuances are to be made, the number of shares to be issued to
each Participant, the vesting schedule (if any) applicable to the issued shares
and the consideration to be paid for such shares.

     C. The Plan Administrator shall have the absolute discretion either to

  V. STOCK SUBJECT TO THE PLAN

                                       3.

<PAGE>




     A. The stock issuable under the Plan shall be shares of authorized but
unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market. The maximum number of shares of Common Stock
which may be issued over the term of the Plan shall not exceed 16,147,572
shares. Such authorized share reserve is comprised of (i) the number of shares
which remain available for issuance, as of the Plan Effective Date, under the
Predecessor Plan as last approved by the Corporation's stockholders, including
the shares subject to the outstanding options incorporated into the Plan, plus
(ii) an additional increase of 5,000,000 shares authorized by the Board but
subject to stockholder approval prior to the Plan Effective Date.

     B. No one person participating in the Plan may receive options, separately
exercisable stock appreciation rights and direct stock issuances for more than
2,700,000 shares of Common Stock in the aggregate over the term of the Plan.

     C. Shares of Common Stock subject to outstanding options shall be available
for subsequent issuance under the Plan to the extent (i) the options (including
any options incorporated from the Predecessor Plan) expire or terminate for any
reason prior to exercise in full or (ii) the options are cancelled in accordance
with the cancellation-regrant provisions of Article Two. All shares issued under
the Plan (including shares issued upon exercise of options incorporated from the
Predecessor Plan), whether or not those shares are subsequently repurchased by
the Corporation pursuant to its repurchase rights under the Plan, shall reduce
on a share-for-share basis the number of shares of Common Stock available for
subsequent issuance under the Plan. In addition, should the exercise price of an
option under the Plan (including any option incorporated from the Predecessor
Plan) be paid with shares of Common Stock or should shares of Common Stock
otherwise issuable under the Plan be withheld by the Corporation in satisfaction
of the withholding taxes incurred in connection with the exercise of an option
or the vesting of a stock issuance under the Plan, then the number of shares of
Common Stock available for issuance under the Plan shall be reduced by the gross
number of shares for which the option is exercised or which vest under the stock
issuance, and not by the net number of shares of Common Stock issued to the
holder of such option or stock issuance.

     D. Should any change be made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities for which any one person may be
granted options, separately exercisable stock appreciation rights and direct
stock issuances over the term of the Plan, (iii) the number and/or class of
securities for which automatic option grants are to be made subsequently per
Eligible Director under the Automatic Option Grant Program and (iv) the number
and/or class of securities and the exercise price per share in effect under each
outstanding option (including any option incorporated from the Predecessor Plan)
in order to prevent the dilution or enlargement of benefits thereunder. The 
adjustments determined by the Plan Administrator shall be final, binding and 
conclusive.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM


  I. OPTION TERMS

     Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
shall comply with the terms specified below. Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

     A. Exercise Price.

     1. The exercise price per share shall be fixed by the Plan Administrator
but shall not be less than eighty-five percent (85%) of the Fair Market Value
per share of Common Stock on the option grant date.

     2. The exercise price shall become immediately due upon exercise of the
option and shall, subject to the provisions of Section I of Article Five and the
documents evidencing the option, be payable in one or more of the forms
specified below:

          (i) cash or check made payable to the Corporation,

          (ii) shares of Common Stock held for the requisite period necessary to
     avoid a charge to the Corporation's earnings for financial reporting
     purposes and valued at Fair Market Value on the Exercise Date, or

          (iii) to the extent the option is exercised for vested shares, through
     a special sale and remittance procedure pursuant to which the Optionee
     shall concurrently provide irrevocable written instructions to (a) a
     Corporation-designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (b) the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

     Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.


                                       5.

<PAGE>



     B. Exercise and Term of Options. Each option shall be exercisable at such
time or times, during such period and for such number of shares as shall be
determined by the Plan Administrator and set forth in the documents evidencing
the option. However, no option shall have a term in excess of ten (10) years
measured from the option grant date.

     C. Effect of Termination of Service.

     1. The following provisions shall govern the exercise of any options held
by the Optionee at the time of cessation of Service or death:

          (i) Any option outstanding at the time of the Optionee's cessation of
     Service for any reason shall remain exercisable for such period of time
     thereafter as shall be determined by the Plan Administrator and set forth
     in the documents evidencing the option, but no such option shall be
     exercisable after the expiration of the option term.

          (ii) Any option exercisable in whole or in part by the Optionee at the
     time of death may be exercised subsequently by the personal representative
     of the Optionee's estate or by the person or persons to whom the option is
     transferred pursuant to the Optionee's will or in accordance with the laws
     of descent and distribution.

          (iii) During the applicable post-Service exercise period, the option
     may not be exercised in the aggregate for more than the number of vested
     shares for which the option is exercisable on the date of the Optionee's
     cessation of Service. Upon the expiration of the applicable exercise period
     or (if earlier) upon the expiration of the option term, the option shall
     terminate and cease to be outstanding for any vested shares for which the
     option has not been exercised. However, the option shall, immediately upon
     the Optionee's cessation of Service, terminate and cease to be outstanding
     to the extent the option is not otherwise at that time exercisable for
     vested shares.

          (iv) Should the Optionee's Service be terminated for Misconduct, then
     all outstanding options held by the Optionee shall terminate immediately
     and cease to be outstanding.

     2. The Plan Administrator shall have the discretion, exercisable either at
the time an option is granted or at any time while the option remains
outstanding, to:

          (i) extend the period of time for which the option is to remain
     exercisable following the Optionee's cessation of Service from the period
     otherwise in effect for that option to such greater period of time as the
     Plan Administrator shall deem appropriate, but in no event beyond the
     expiration of the option term, and/or


                                       6.

<PAGE>


          (ii) permit the option to be exercised, during the applicable
     post-Service exercise period, not only with respect to the number of vested
     shares of Common Stock for which such option is exercisable at the time of
     the Optionee's cessation of Service but also with respect to one or more
     additional installments in which the Optionee would have vested under the
     option had the Optionee continued in Service.

     D. Stockholder Rights. The holder of an option shall have no stockholder
rights with respect to the shares subject to the option until such person shall
have exercised the option, paid the exercise price and become a holder of record
of the purchased shares.

     E. Repurchase Rights. The Plan Administrator shall have the discretion to
grant options which are exercisable for unvested shares of Common Stock. Should
the Optionee cease Service while holding such unvested shares, the Corporation
shall have the right to repurchase, at the exercise price paid per share, any or
all of those unvested shares. The terms upon which such repurchase right shall
be exercisable (including the period and procedure for exercise and the
appropriate vesting schedule for the purchased shares) shall be established by
the Plan Administrator and set forth in the document evidencing such repurchase
right.

     F. Limited Transferability of Options. During the lifetime of the Optionee,
Incentive Options shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death. However, a Non-Statutory Option
may, in connection with the Optionee's estate plan, be assigned in whole or in
part during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust established exclusively for the benefit of one or
more such family members. The assigned portion may only be exercised by the
person or persons who acquire a proprietary interest in the option pursuant to
the assignment. The terms applicable to the assigned portion shall be the same
as those in effect for the option immediately prior to such assignment and shall
be set forth in such documents issued to the assignee as the Plan Administrator
may deem appropriate.

 II. INCENTIVE OPTIONS

     The terms specified below shall be applicable to all Incentive Options.
Except as modified by the provisions of this Section II, all the provisions of
Articles One, Two and Five shall be applicable to Incentive Options. Options
which are specifically designated as Non-Statutory Options when issued under the
Plan shall not be subject to the terms of this Section II.

     A. Eligibility. Incentive Options may only be granted to Employees.

     B. Exercise Price. The exercise price per share shall not be less than one
hundred percent (100%) of the Fair Market Value per share of Common Stock on the
option grant date.


                                       7.

<PAGE>


     C. Dollar Limitation. The aggregate Fair Market Value of the shares of
Common Stock (determined as of the respective date or dates of grant) for which
one or more options granted to any Employee under the Plan (or any other option
plan of the Corporation or any Parent or Subsidiary) may for the first time
become exercisable as Incentive Options during any one (1) calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the
Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

     D. 10% Stockholder. If any Employee to whom an Incentive Option is granted
is a 10% Stockholder, then the exercise price per share shall not be less than
one hundred ten percent (110%) of the Fair Market Value per share of Common
Stock on the option grant date, and the option term shall not exceed five (5)
years measured from the option grant date.

III. CORPORATE TRANSACTION/CHANGE IN CONTROL

     A. In the event of any Corporate Transaction, each outstanding option shall
automatically accelerate so that each such option shall, immediately prior to
the effective date of the Corporate Transaction, become fully exercisable for
all of the shares of Common Stock at the time subject to such option and may be
exercised for any or all of those shares as fully-vested shares of Common Stock.
However, an outstanding option shall not so accelerate if and to the extent: (i)
such option is, in connection with the Corporate Transaction, either to be
assumed by the successor corporation (or parent thereof) or to be replaced with
a comparable option to purchase shares of the capital stock of the successor
corporation (or parent thereof), (ii) such option is to be replaced with a cash
incentive program of the successor corporation which preserves the spread
existing on the unvested option shares at the time of the Corporate Transaction
and provides for subsequent payout in accordance with the same vesting schedule
applicable to such option or (iii) the acceleration of such option is subject to
other limitations imposed by the Plan Administrator at the time of the option
grant. The determination of option comparability under clause (i) above shall be
made by the Plan Administrator, and its determination shall be final, binding
and conclusive.

     B. All outstanding repurchase rights shall also terminate automatically,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.
                                                                               
     C. The Plan Administrator shall have the discretion, exercisable either at
the time the option is granted or at any time while the option remains         
outstanding, to provide for the automatic acceleration of one or more          
outstanding options (and the automatic termination of one or more outstanding  
repurchase rights with the immediate vesting of the shares of Common Stock     


                                       8.

<PAGE>


subject to those rights) upon the occurrence of a Corporate Transaction, whether
or not those options are to be assumed or replaced (or those repurchase rights
are to be assigned) in the Corporate Transaction. The Plan Administrator shall
also have the discretion to grant options which do not accelerate whether or not
such options are assumed (and to provide for repurchase rights that do not
terminate whether or not such rights are assigned) in connection with a
Corporate Transaction.

     D. Immediately following the consummation of the Corporate Transaction, all
outstanding options shall terminate and cease to be outstanding, except to the
extent assumed by the successor corporation (or parent thereof).

     E. Each option which is assumed in connection with a Corporate Transaction
shall be appropriately adjusted, immediately after such Corporate Transaction,
to apply to the number and class of securities which would have been issuable to
the Optionee in consummation of such Corporate Transaction had the option been
exercised immediately prior to such Corporate Transaction. Appropriate
adjustments shall also be made to (i) the number and class of securities
available for issuance under the Plan following the consummation of such
Corporate Transaction, (ii) the exercise price payable per share under each
outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same and (iii) the maximum number of securities
and/or class of securities for which any one person may be granted stock
options, separately exercisable stock appreciation rights and direct stock
issuances under the Plan.

     F. The Plan Administrator shall have the discretion, exercisable at the
time the option is granted or at any time while the option remains outstanding,
to provide for the automatic acceleration of any options which are assumed or
replaced in a Corporate Transaction and do not otherwise accelerate at that time
(and the termination of any of the Corporation's outstanding repurchase rights
which do not otherwise terminate at the time of the Corporate Transaction) in
the event the Optionee's Service should subsequently terminate by reason of an
Involuntary Termination within eighteen (18) months following the effective date
of such Corporate Transaction. Any options so accelerated shall remain
exercisable for fully-vested shares until the earlier of (i) the expiration of
the option term or (ii) the expiration of the one (1)-year period measured from
the effective date of the Involuntary Termination.

     G. The Plan Administrator shall have the discretion, exercisable either at 
the time the option is granted or at any time while the option remains          
outstanding, to (i) provide for the automatic acceleration of one or more       
outstanding options (and the automatic termination of one or more outstanding   
repurchase rights with the immediate vesting of the shares of Common Stock      
subject to those rights) upon the occurrence of a Change in Control or (ii)     
condition any such option acceleration (and the termination of any outstanding  
repurchase rights) upon the subsequent Involuntary Termination of the Optionee's
Service within a specified period following the effective date of such Change in
Control. Any options accelerated in connection with a Change in Control shall   
remain fully exercisable until the expiration or sooner termination of the      
option term.                                                                    


                                       9.

<PAGE>


     H. The portion of any Incentive Option accelerated in connection with a
Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
($100,000) limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a
Non-Statutory Option under the Federal tax laws.

     I. The grant of options under the Discretionary Option Grant Program shall
in no way affect the right of the Corporation to adjust, reclassify, reorganize
or otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

 IV. CANCELLATION AND REGRANT OF OPTIONS

     The Plan Administrator shall have the authority to effect, at any time and
from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

  V. STOCK APPRECIATION RIGHTS

     A. The Plan Administrator shall have full power and authority to grant to
selected Optionees tandem stock appreciation rights and/or limited stock
appreciation rights.

     B. The following terms shall govern the grant and exercise of tandem stock
appreciation rights:

          (i) One or more Optionees may be granted the right, exercisable upon
     such terms as the Plan Administrator may establish, to elect between the
     exercise of the underlying option for shares of Common Stock and the 
     surrender of that option in exchange for a distribution from the 
     Corporation in an amount equal to the excess of (a) the Fair Market Value
     (on the option surrender date) of the number of shares in which the
     Optionee is at the time vested under the surrendered option (or surrendered
     portion thereof) over (b) the aggregate exercise price payable for such
     shares.

          (ii) No such option surrender shall be effective unless it is approved
     by the Plan Administrator. If the surrender is so approved, then the
     distribution to which the Optionee shall be entitled may be made in shares
     of Common Stock valued at Fair Market Value on the option surrender date,
     in cash, or partly in shares and partly in cash, as the Plan Administrator
     shall in its sole discretion deem appropriate.


                                       10.

<PAGE>


          (iii) If the surrender of an option is rejected by the Plan
     Administrator, then the Optionee shall retain whatever rights the Optionee
     had under the surrendered option (or surrendered portion thereof) on the
     option surrender date and may exercise such rights at any time prior to the
     later of (a) five (5) business days after the receipt of the rejection
     notice or (b) the last day on which the option is otherwise exercisable in
     accordance with the terms of the documents evidencing such option, but in
     no event may such rights be exercised more than ten (10) years after the
     option grant date.

     C. The following terms shall govern the grant and exercise of limited stock
appreciation rights:

          (i) One or more Section 16 Insiders may be granted limited stock
     appreciation rights with respect to their outstanding options.

          (ii) Upon the occurrence of a Hostile Take-Over, each such individual
     holding one or more options with such a limited stock appreciation right
     shall have the unconditional right (exercisable for a thirty (30)-day
     period following such Hostile Take-Over) to surrender each such option to
     the Corporation, to the extent the option is at the time exercisable for
     vested shares of Common Stock. In return for the surrendered option, the
     Optionee shall receive a cash distribution from the Corporation in an
     amount equal to the excess of (a) the Take-Over Price of the shares of
     Common Stock which are at the time vested under each surrendered option (or
     surrendered portion thereof) over (b) the aggregate exercise price payable
     for such shares. Such cash distribution shall be paid within five (5) days
     following the option surrender date.

                                                                                
          (iii) Neither the approval of the Plan Administrator nor the consent  
     of the Board shall be required in connection with such option surrender and
     cash distribution.                                                         
                                                                                
          (iv) The balance of the option (if any) shall continue in full force  
     and effect in accordance with the documents evidencing such option.

                             STOCK ISSUANCE PROGRAM


  I. STOCK ISSUANCE TERMS

     Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

     A. Purchase Price.

     1. The purchase price per share shall be fixed by the Plan Administrator,
but shall not be less than eighty-five percent (85%) of the Fair Market Value
per share of Common Stock on the issuance date.

     2. Subject to the provisions of Section I of Article Five, shares of Common
Stock may be issued under the Stock Issuance Program for any of the following
items of consideration which the Plan Administrator may deem appropriate in each
individual instance:

          (i) cash or check made payable to the Corporation, or

          (ii) past services rendered to the Corporation (or any Parent or
     Subsidiary).

     B. Vesting Provisions.

     1. Shares of Common Stock issued under the Stock Issuance Program may, in
the discretion of the Plan Administrator, be fully and immediately vested upon
issuance or may vest in one or more installments over the Participant's period
of Service or upon attainment of specified performance objectives. The elements
of the vesting schedule applicable to any unvested shares of Common Stock issued
under the Stock Issuance Program, namely:

          (i) the Service period to be completed by the Participant or the
     performance objectives to be attained,

          (ii) the number of installments in which the shares are to vest,

          (iii) the interval or intervals (if any) which are to lapse between
     installments, and


                                       12.

<PAGE>


          (iv) the effect which death, Permanent Disability or other event
     designated by the Plan Administrator is to have upon the vesting schedule,

shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

     2. Any new, substituted or additional securities or other property
(including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

     3. The Participant shall have full stockholder rights with respect to any
shares of Common Stock issued to the Participant under the Stock Issuance
Program, whether or not the Participant's interest in those shares is vested.
Accordingly, the Participant shall have the right to vote such shares and to
receive any regular cash dividends paid on such shares.

     4. Should the Participant cease to remain in Service while holding one or
more unvested shares of Common Stock issued under the Stock Issuance Program or
should the performance objectives not be attained with respect to one or more
such unvested shares of Common Stock, then those shares shall be immediately
surrendered to the Corporation for cancellation, and the Participant shall have
no further stockholder rights with respect to those shares. To the extent the
surrendered shares were previously issued to the Participant for consideration
paid in cash or cash equivalent (including the Participant's purchase-money
indebtedness), the Corporation shall repay to the Participant the cash
consideration paid for the surrendered shares and shall cancel the unpaid
principal balance of any outstanding purchase-money note of the Participant
attributable to the surrendered shares.

     5. The Plan Administrator may in its discretion waive the surrender and
cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the cessation of the
Participant's Service or the non-attainment of the performance objectives
applicable to those shares. Such waiver shall result in the immediate vesting of
the Participant's interest in the shares of Common Stock as to which the waiver
applies. Such waiver may be effected at any time, whether before or after the 
Participant's cessation of Service or the attainment or non-attainment of 
the applicable performance objectives.                     
                                                                                
    II.    CORPORATE TRANSACTION/CHANGE IN CONTROL                              

     A. All outstanding cancellation rights under the Stock Issuance Program  
shall terminate automatically, and all the shares of Common Stock subject to  
those terminated rights                                                       


                                       13.

<PAGE>


shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent (i) those cancellation rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed in the
Stock Issuance Agreement.

     B. The Plan Administrator shall have the discretion, exercisable either 
at the time the unvested shares are issued or at any time while the 
Corporation's cancellation rights remain outstanding to provide that any 
cancellation rights that are assigned in the Corporate Transaction shall 
automatically terminate, and the shares of Common Stock subject to those 
terminated rights shall immediately vest in full, in the event the 
Participant's Service should subsequently terminate by reason of an 
Involuntary Termination within eighteen (18) months following the effective 
date of such Corporate Transaction.

     C. The Plan Administrator shall have the discretion to provide for
cancellation rights with terms different from those in effect under this Section
II in connection with a Corporate Transaction.

     D. The Plan Administrator shall have the discretion, exercisable either at
the time the unvested shares are issued or at any time while the Corporation's
cancellation right remains outstanding, to (i) provide for the automatic
termination of one or more outstanding cancellation rights and the immediate
vesting of the shares of Common Stock subject to those rights upon the
occurrence of a Change in Control or (ii) condition any such accelerated vesting
upon the subsequent Involuntary Termination of the Participant's Service within
a specified period following the effective date of such Change in Control.

III. SHARE ESCROW/LEGENDS

     Unvested shares may, in the Plan Administrator's discretion, be held in
escrow by the Corporation until the Participant's interest in such shares vests
or may be issued directly to the Participant with restrictive legends on the
certificates evidencing those unvested shares.

                                       14.

                         AUTOMATIC OPTION GRANT PROGRAM


  I. OPTION TERMS

     A. Grant Dates. Option grants shall be made on the dates specified below:

     1. Each individual who is first elected or appointed as a non-employee
Board member on or after the Underwriting Date shall automatically be granted,
on the date of such initial election or appointment, a Non-Statutory Option to
purchase 200,000 shares of Common Stock, provided such individual has not
previously been in the employ of the corporation (or any Parent or Subsidiary).

     2. On the date of each Annual Stockholders Meeting held after the
Underwriting Date, each individual who is to continue to serve as an Eligible
Director, shall automatically be granted a Non-Statutory Option to purchase an
additional 40,000 shares of Common Stock, provided such individual has served as
a non-employee Board member for at least six (6) months. There shall be no limit
on the number of such 40,000-share option grants any one Eligible Director may
receive over his or her period of Board service.

     B. Exercise Price.

     1. The exercise price per share shall be equal to one hundred percent
(100%) of the Fair Market Value per share of Common Stock on the option grant
date.

     2. The exercise price shall be payable in one or more of the alternative
forms authorized under the Discretionary Option Grant Program. Except to the
extent the sale and remittance procedure specified thereunder is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

     C. Option Term. Each option shall have a term of ten (10) years measured
from the option grant date.

     D. Exercise and Vesting of Options. Each option shall be immediately
exercisable for any or all of the option shares. However, any shares purchased
under the option shall be subject to repurchase by the Corporation, at the
exercise price paid per share, upon the Optionee's cessation of Board service
prior to vesting in those shares. Each initial grant shall vest, and the
Corporation's repurchase right shall lapse, in a series of four (4) successive
equal annual installments over the Optionee's period of continued service as
a Board member, with the first such installment to vest upon the Optionee's     
completion of one (1) year of Board service measured from the option grant date.
Each annual grant shall vest, and the Corporation's                             


                                       15.

<PAGE>


repurchase right shall lapse, upon the Optionee's completion of one (1) year of
Board service measured from the option grant date.

     E. Effect of Termination of Board Service. The following provisions shall
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

          (i) The Optionee (or, in the event of Optionee's death, the personal
     representative of the Optionee's estate or the person or persons to whom
     the option is transferred pursuant to the Optionee's will or in accordance
     with the laws of descent and distribution) shall have a twelve (12)- month
     period following the date of such cessation of Board service in which to
     exercise each such option.

          (ii) During the twelve (12)-month exercise period, the option may not
     be exercised in the aggregate for more than the number of vested shares of
     Common Stock for which the option is exercisable at the time of the
     Optionee's cessation of Board service.

          (iii) Should the Optionee cease to serve as a Board member by reason
     of death or Permanent Disability, then all shares at the time subject to
     the option shall immediately vest so that such option may, during the
     twelve (12)-month exercise period following such cessation of Board
     service, be exercised for all or any portion of those shares as
     fully-vested shares of Common Stock.

          (iv) In no event shall the option remain exercisable after the
     expiration of the option term. Upon the expiration of the twelve (12)-month
     exercise period or (if earlier) upon the expiration of the option term, the
     option shall terminate and cease to be outstanding for any vested shares
     for which the option has not been exercised. However, the option shall,
     immediately upon the Optionee's cessation of Board service for any reason
     other than death or Permanent Disability, terminate and cease to be
     outstanding to the extent the option is not otherwise at that time
     exercisable for vested shares.

 II. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKEOVER

     A. In the event of any Corporate Transaction, the shares of Common Stock at
the time subject to each outstanding option but not otherwise vested shall
automatically vest in full so that each such option shall, immediately prior to
the effective date of the Corporate Transaction, become fully exercisable for
all of the shares of Common Stock at the time subject to such option and may be
exercised for all or any portion of those shares as fully-vested shares of
Common Stock. Immediately following the consummation of the Corporate
Transaction, each

                                       16.

<PAGE>


automatic option grant shall terminate and cease to be outstanding, except to
the extent assumed by the successor corporation (or parent thereof).

     B. In connection with any Change in Control, the shares of Common Stock at
the time subject to each outstanding option but not otherwise vested shall
automatically vest in full so that each such option shall, immediately prior to
the effective date of the Change in Control, become fully exercisable for all of
the shares of Common Stock at the time subject to such option and may be
exercised for all or any portion of those shares as fully-vested shares of
Common Stock. Each such option shall remain exercisable for such fully-vested
option shares until the expiration or sooner termination of the option term 
or the surrender of the option in connnection with a Hostile Take-Over.

     C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a
thirty (30)-day period in which to surrender to the Corporation each of his or
her outstanding automatic option grants. The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares. Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation. No approval or consent
of the Board or any Plan Administrator shall be required in connection with such
option surrender and cash distribution.

     D. Each option which is assumed in connection with a Corporate Transaction
shall be appropriately adjusted, immediately after such Corporate Transaction,
to apply to the number and class of securities which would have been issuable to
the Optionee in consummation of such Corporate Transaction had the option been
exercised immediately prior to such Corporate Transaction. Appropriate
adjustments shall also be made to the exercise price payable per share under
each outstanding option, provided the aggregate exercise price payable for such
securities shall remain the same.

     E. The grant of options under the Automatic Option Grant Program shall in
no way affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

III. REMAINING TERMS

     The remaining terms of each option granted under the Automatic Option Grant
Program shall be the same as the terms in effect for option grants made under
the Discretionary Option Grant Program.

                                  MISCELLANEOUS


  I. FINANCING

     A. The Plan Administrator may permit any Optionee or Participant to pay the
option exercise price under the Discretionary Option Grant Program or the
purchase price for shares issued under the Stock Issuance Program by delivering
a promissory note payable in one or more installments. The terms of any such
promissory note (including the interest rate and the terms of repayment) shall
be established by the Plan Administrator in its sole discretion. Promissory
notes may be authorized with or without security or collateral. In all events,
the maximum credit available to the Optionee or Participant may not exceed the
sum of (i) the aggregate option exercise price or purchase price payable for the
purchased shares plus (ii) any Federal, state and local income and employment
tax liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

     B. The Plan Administrator may, in its discretion, determine that one or
more such promissory notes shall be subject to forgiveness by the Corporation in
whole or in part upon such terms as the Plan Administrator may deem appropriate.

 II. TAX WITHHOLDING

     A. The Corporation's obligation to deliver shares of Common Stock upon the
exercise of options or upon the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

     B. The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant Program) with the right to use shares of Common Stock in
satisfaction of all or part of the Taxes incurred by such holders in connection
with the exercise of their options or the vesting of their shares. Such right
may be provided to any such holder in either or both of the following formats:

          (i) Stock Withholding: The election to have the Corporation withhold,
     from the shares of Common Stock otherwise issuable upon the exercise of
     such Non-Statutory Option or the vesting of such shares, a portion of those
     shares with an aggregate Fair Market Value equal to the percentage of the
     Taxes (not to exceed one hundred percent (100%)) designated by the holder.


                                       18.

<PAGE>


          (ii) Stock Delivery: The election to deliver to the Corporation, at
     the time the Non-Statutory Option is exercised or the shares vest, one or
     more shares of Common Stock previously acquired by such holder (other than
     in connection with the option exercise or share vesting triggering the
     Taxes) with an aggregate Fair Market Value equal to the percentage of the
     Taxes (not to exceed one hundred percent (100%)) designated by the holder.

III. EFFECTIVE DATE AND TERM OF THE PLAN

     A. The Plan shall become effective on the Plan Effective Date. Options may
be granted under the Discretionary Option Grant Program at any time on or after
the Plan Effective Date. The Automatic Option Grant Program shall become
effective on the Underwriting Date and the initial options under that program
shall be made to the Eligible Directors at that time. However, no options
granted under the Plan may be exercised, and no shares shall be issued under the
Plan, until the Plan is approved by the Corporation's stockholders. If such
stockholder approval is not obtained within twelve (12) months after the date
the Plan is adopted by the Board, then all options previously granted under this
Plan shall terminate and cease to be outstanding, and no further options shall
be granted and no shares shall be issued under the Plan.

     B. The Plan shall serve as the successor to the Predecessor Plan, and no
further option grants shall be made under the Predecessor Plan after the Plan
Effective Date. All options outstanding under the Predecessor Plan as of such
date shall be incorporated into the Plan at that time and shall be treated as
outstanding options under the Plan. However, each outstanding option so
incorporated shall continue to be governed solely by the terms of the documents
evidencing such option, and no provision of the Plan shall be deemed to affect
or otherwise modify the rights or obligations of the holders of such
incorporated options with respect to their acquisition of shares of Common
Stock.

     C. One or more provisions of the Plan, including (without limitation) the
option/vesting acceleration provisions of Article Two relating to Corporate
Transactions and Changes in Control, may, in the Plan Administrator's
discretion, be extended to one or more options incorporated from the Predecessor
Plan which do not otherwise contain such provisions.

     D. The Plan shall terminate upon the earliest of (i) June 29, 2006, (ii)
the date on which all shares available for issuance under the Plan shall have
been issued pursuant to the exercise of the options or the issuance of shares
(whether vested or unvested) under the Plan or (iii) the termination of all
outstanding options in connection with a Corporate Transaction. Upon such Plan
termination, all outstanding options and unvested stock issuances shall continue
to have force and effect in accordance with the provisions of the documents
evidencing such options or issuances.
                                                                               
  IV. AMENDMENT OF THE PLAN

     A. The Board shall have complete and exclusive power and authority to amend
or modify the Plan in any or all respects. However, no such amendment or
modification shall adversely affect any rights and obligations with respect to
options, stock appreciation rights or unvested stock issuances at the time
outstanding under the Plan unless the Optionee or the Participant consents to
such amendment or modification. In addition, amendments to the Plan shall be
subject to approval of the Corporation's stockholders to the extent required by
applicable laws or regulations.

     B. Options to purchase shares of Common Stock may be granted under the
Discretionary Option Grant Program and shares of Common Stock may be issued
under the Stock Issuance Program that are in each instance in excess of the
number of shares then available for issuance under the Plan, provided any excess
shares actually issued under those programs are held in escrow until there is
obtained stockholder approval of an amendment sufficiently increasing the number
of shares of Common Stock available for issuance under the Plan. If such
stockholder approval is not obtained within twelve (12) months after the date
the first such excess grants or issuances are made, then (i) any unexercised
options granted on the basis of such excess shares shall terminate and cease to
be outstanding and (ii) the Corporation shall promptly refund to the Optionees
and the Participants the exercise or purchase price paid for any excess shares
issued under the Plan and held in escrow, together with interest (at the
applicable Short Term Federal Rate) for the period the shares were held in
escrow, and such shares shall thereupon be automatically cancelled and cease to
be outstanding.

  V. USE OF PROCEEDS

     Any cash proceeds received by the Corporation from the sale of shares of
Common Stock under the Plan shall be used for general corporate purposes.

 VI. REGULATORY APPROVALS

     A. The implementation of the Plan, the granting of any option or stock
appreciation right under the Plan and the issuance of any shares of Common Stock
(i) upon the exercise of any option or stock appreciation right or (ii) under
the Stock Issuance Program shall be subject to the Corporation's procurement of
all approvals and permits required by regulatory authorities having jurisdiction
over the Plan, the options and stock appreciation rights granted under it and
the shares of Common Stock issued pursuant to it.

     B. No shares of Common Stock or other assets shall be issued or delivered
under the Plan unless and until there shall have been compliance with all
applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.
                                                                               
VII. NO EMPLOYMENT/SERVICE RIGHTS                                              

                                       20.

<PAGE>


     Nothing in the Plan shall confer upon the Optionee or the Participant any
right to continue in Service for any period of specific duration or interfere
with or otherwise restrict in any way the rights of the Corporation (or any
Parent or Subsidiary employing or retaining such person) or of the Optionee or
the Participant, which rights are hereby expressly reserved by each, to
terminate such person's Service at any time for any reason, with or without
cause.

                              DIGITRAN CORPORATION
              INCORPORATED UNDER THE LAWS OF THE STATE OF DELAWARE

     THIS CERTIFIES THAT, for value received, [Investor] (the "Investor") is
entitled to purchase, on the terms hereof, [ ] shares of Series C Preferred
Stock of Digitran Corporation, a Delaware corporation (the "Company") , with the
designations, powers, preferences, rights, qualifications, limitations and
restrictions set forth in the Second Amended and Restate Certificate of
Incorporation of the Company at a per share purchase price of $.60, subject to
adjustment as provided herein.

     This Warrant is issued pursuant to the following terms and provisions:

     1.   Exercise of Warrant.

     The terms and conditions upon which this Warrant may be exercised, and the
Series C Preferred Stock covered hereby (the "Warrant Stock") may be purchased,
are as follows:

     1.1 Voluntary Exercise. This Warrant may be exercised in full or in part at
any time after the date hereof, but in no case may this Warrant be exercised
later than the close of business on December 31, 1996 (the "Termination Date"),
after which time this Warrant shall terminate and shall be void and of no
further force or effect.

     1.2 Purchase Price. The per share purchase price for the shares of Series C
Preferred Stock to be issued upon exercise of this Warrant shall be $.60,
subject to adjustment as provided herein.

     1.3 Method of Exercise. The exercise of the purchase rights evidenced by
this Warrant shall be effected by (a) the surrender of the Warrant, together
with a duly executed copy of the form of subscription attached hereto, to the
Company at its principal offices and (b) the delivery of the purchase price by
check or bank 

<PAGE>


draft payable to the Company's order or by wire transfer to the Company's
account for the number of shares for which the purchase rights hereunder are
being exercised or any other form of consideration approved by the Company's
Board of Directors.

     1.4 Issuance of Shares. Upon the exercise of the purchase rights evidenced
by this Warrant, a certificate or certificates for the purchased shares shall be
issued to the Investor as soon as possible.

     2. Certain Adjustments.

     2.1 Conversion or Redemption of Series C Preferred Stock. Should all of the
Company's outstanding Series C Preferred Stock be, at any time prior to the
expiration of this Warrant, converted into shares of the Company's Common Stock
in accordance with the Company's Certificate of Incorporation, as amended and/or
restated and effective immediately prior to the conversion of all of the
Company's Series C Preferred Stock (the "Certificate"), then this Warrant shall
immediately become exercisable for that number of shares of the Company's Common
Stock equal to the number of shares of Common Stock which would have been
received if this Warrant had been exercised in full and the Warrant Stock
received thereupon had been simultaneously converted into Common Stock
immediately prior to such event. The per share purchase price shall be
immediately adjusted to equal the quotient obtained by dividing (x) the
aggregated purchase price of the number of shares of Series C Preferred Stock
for which this Warrant was exercisable immediately prior to such conversion by
(y) the number of shares of Common Stock for which this Warrant is exercisable
immediately after such conversion or redemption.

     2.2 Common Stock Dividends. If at any time following the conversion of all
the outstanding Series C Preferred Stock and prior to the expiration of this
Warrant, there shall be an event with respect to the Common Stock of the type
referred to in Section 2.4 or 2.5, then the provisions of such Sections with
respect to Series C Preferred Stock shall apply mutatis mutandis to the Common
Stock issuable upon the exercise of this Warrant and the Purchase Price thereof.

     2.3 Mergers, Consolidations or Sale of Assets. If at any time there shall
be a capital reorganization (other than a combination or subdivision of Warrant
Stock otherwise provided for herein), or a merger or consolidation of the
Company with or into another corporation, or the sale of the Company's
properties and assets as, or substantially as, an entirety to any other person,
then, as part of such reorganization, merger, consolidation or sale, lawful
provision shall be made so that the Investor shall thereafter be entitled to
receive upon exercise of this Warrant, during the period specified in this
Warrant and upon payment of the purchase price, the number of shares of stock or
other securities

                                      -2-


<PAGE>


or property of the Company or the successor corporation resulting from such
reorganization, merger, consolidation or sale, to which a holder of the Series C
Preferred Stock (or Common Stock issuable upon conversion thereof) deliverable
upon exercise of this Warrant would have been entitled under the provisions of
the agreement in such reorganization, merger, consolidation or sale if this
Warrant had been exercised immediately before that reorganization, merger,
consolidation or sale. In any such case, appropriate adjustment (as determined
in good faith by the Company's Board of Directors) shall be made in the
application of the provisions of this Warrant with respect to the rights and
interests of the Investor after the reorganization, merger, consolidation or
sale to the end that the provisions of this Warrant (including adjustment of the
purchase price then in effect and the number of shares of Warrant Stock) shall
be applicable after that event, as near as reasonably may be, in relation to any
shares or other property deliverable after that event upon exercise of this
Warrant.

     2.4 Splits and Subdivisions. In the event the Company should at any time or
from time to time fix a record date for the effectuation of a split or
subdivision of the outstanding shares of Series C Preferred Stock or the
determination of the holders of Series C Preferred Stock entitled to received a
dividend or other distribution payable in additional shares of Series C
Preferred Stock or other securities or rights convertible into, or entitling the
holder thereof to receive directly or indirectly, additional shares of Series C
Preferred Stock (hereinafter referred to as the "Series C Equivalents") without
payment of any consideration by such holder for the additional shares of Series
C Preferred Stock or Series C Equivalents (including the additional shares of
Series C Preferred Stock issuable upon conversion or exercise thereof), the, as
of such record date (or the date of such distribution, split or subdivision if
no record date is fixed), the purchase price should be appropriately decreased
and the number of shares of Warrant Stock shall be appropriately increased in
proportion to such increase of outstanding shares.

     2.5 Combination of Shares. If the number of shares of Series C Preferred
Stock outstanding at any time after the date hereof is decreased by a
combination of the outstanding shares of Series C Preferred Stock, the purchase
price shall be appropriately increased and the number of shares of Warrant Stock
shall be appropriately decreased in proportion to such decrease in outstanding
shares.

     2.6 Adjustments for Other Distribution. In the event the Company shall
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Company or other persons, assets (excluding cash
dividends) or options or rights not referred to in subsection 2.4, then, in each
such case for the purpose of this subsection 2.6, upon exercise of this Warrant
the holder thereof shall be entitled to a proportionate share of any

                                       -3-

<PAGE>



such distribution as though such holder was the holder of the number of shares
of Series C Preferred Stock of the Company into which this Warrant may be
exercised as of the record date fixed for the determination of the holders of
Series C Preferred Stock of the Company entitled to receive such distribution.

     2.7 Certificate as to Adjustments. In the case of each adjustment or
readjustment of the purchase price pursuant to this Section 2, the Company will
promptly compute such adjustment or readjustments in accordance with the terms
hereof and cause a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based
to be delivered to the holder of this Warrant. The Company will, upon the
written request at any time of the holder of this Warrant, furnish or cause to
be furnished to such holder a certificate setting forth:

     (a)  Such adjustments and readjustments;

     (b)  The purchase price at the time in effect; and

     (c)  The number of shares of Warrant Stock and the amount, if any, of other
          property at the time receivable upon the exercise of the Warrant.

     2.8 Notices of Record Date, etc. In the event of:

     (a) Any taking by the Company of a record of the holders of any class of
securities of the Company for the purpose of determining the holders thereof who
are entitled to receive any dividend (other than a cash dividend payable out of
earned surplus at the same rate as that of the last such cash dividend
theretofore paid) or other distribution, or any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right; or

     (b) Any capital reorganization of the Company, any reclassification or
recapitalization of the capital stock of the Company or any transfer of all or
substantially all of the assets of the Company to any other person or any
consolidation or merger involving the Company; or

     (c) Any voluntary or involuntary dissolution, liquidation or winding-up of
the Company;

     the Company will mail to the holder of this Warrant at least twenty (20)
days prior to the earliest date specified therein, a notice specifying:

     (i)  The date on which any such record is to be taken for the purpose of
          such dividend, distribution or right, and the amount and

                                       -4-

<PAGE>



          character of such dividend, distribution or right; and

     (ii) The date on which any such reorganization, reclassification, transfer,
          consolidation, merger, dissolution, liquidation or winding-up is
          expected to become effective and the record date for determining
          stockholders entitled to vote thereon.

     3. Fractional Shares. No fractional shares shall be issued in connection
with any exercise of this Warrant. In lieu of the issuance of such fractional
share, the Company shall make a cash payment equal to the then fair market value
of such fractional share as determined in good faith by the Company's Board of
Directors.

     4. Reservation of Series C Preferred Stock and Common Stock. The Company
shall at all times reserve and keep available out of its authorized but unissued
shares of Preferred Stock and Common Stock, solely for the purpose of effecting
the exercise of this Warrant such number of its shares of Series C Preferred
Stock (and Common Stock upon conversion of the Series C Preferred Stock) as
shall from time to time be sufficient to effect the exercise of this Warrant;
and if at any time the number of authorized but unissued shares of Series C
Preferred Stock or Common Stock shall not be sufficient to effect the exercise
of the entire Warrant and the conversion of the Series C Preferred Stock
thereafter, in addition to such other remedies as shall be available to the
holder of this Warrant, the Company will use its reasonable best efforts to take
such corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of Series C Preferred Stock or
Common Stock to such number of shares as shall be sufficient for such purpose.

     5. Privilege of Stock Ownership. Prior to the exercise of this Warrant, the
Investor shall not be entitled, by virtue of holding this Warrant, to any rights
of a stockholder of the Company. However, nothing in this Section 5, shall limit
the right of the Investor to participate in distributions described in Section 2
hereof if Investor ultimately exercises this Warrant.

     6. Limitation of Liability. Except as otherwise provided herein, in the
absence of affirmative action by the holder hereof to purchase the Warrant
Stock, no mere enumeration herein of the rights or privileges of the holder
hereof shall give rise to any liability of such holder for the purchase price or
as a stockholder of the Company, whether such liability is asserted by the
Company or by creditors of the Company.

     7. Transfers and Exchanges.

     7.1 Subject to compliance with applicable federal and state securities
laws, this Warrant and all rights hereunder are transferable in whole or in part
by the Investor to any person or entity. The Investor will provide written
notice of such transfer to the Company, and if no written objection is received
by the Investor within ten (10) days after the date of notice, then such
transfer shall be deemed accepted by the Company. The transfer shall be recorded
on the books of the Company upon the surrender of this Warrant, properly
endorsed, to the Company at its principal offices and the payment to the Company
of all transfer taxes and other governmental charges imposed on such transfer.
In the event of a partial transfer, the Company shall issue to the several
holders one or more appropriate new warrants.

partial exercises shall be identical in form and provision to this Warrant
except as to the number of shares.

be binding upon the Company and the Investor and their respective successors and
assigns.

                  To Purchase Shares of the Preferred Stock of
                              Digitran Corporation
                            dated as of May 30, 1991

     WHEREAS, Digitran Corporation, a Delaware corporation (the "Company") has
entered into a Master Lease Agreement dated as of May 30, 1991, Equipment
Schedule #VL-1, and related Summary Equipment Schedules (the "Leases") with
Comdisco, Inc., a Delaware corporation (the "Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Leases, the right to purchase shares of its Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Leases and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder certify and agree as follows:

     1. GRANT OF THE RIGHT TO PURCHASE PREFERRED STOCK. For value received, the
Company hereby grants to the Warrantholder, and the Warrantholder is entitled,
upon the terms and subject to the conditions hereinafter set forth, to subscribe
for and purchase, from the Company, 60,000 fully paid and non-assessable shares
of the Company's Preferred Series B Stock ("Preferred Stock") at a purchase
price of $1.00 per share (the "Exercise Price"). The number and purchase price
of such shares are subject to adjustment as provided in Section 8 hereof.

     2.(a) TERM OF THE WARRANT AGREEMENT. Except as otherwise provided for
herein, the term of this Warrant Agreement and the right to purchase Preferred
Stock as granted herein shall commence on the date of execution hereof and shall
be exercisable for a period of (i) ten (10) years after the date of execution
hereof, or (ii) or in accordance with paragraphs (b) or (c) below.

     (b) Notwithstanding the term of this Warrant Agreement fixed pursuant to
Section 2(a) above, the right to purchase Preferred Stock as granted herein
shall expire, if not previously exercised immediately upon the closing of either
of the following events:

     (i)  the issuance and sale of shares of Common Stock of the Company in the
          Company's first public offering of securities for its own account
          pursuant to an effective

<PAGE>


          registration statement under the Securities Act of 1933, as amended
          (the "Initial Public Offering"), provided, however, that (A) the
          Initial Public Offering price of the Common Stock (upon conversion of
          the Preferred Stock) exceeds $3.00 per share; and (B) the
          Warrantholder would be entitled to participate in the Company's IPO
          pro rata with the other stockholders of the Company.

     (ii) a merger or consolidation of the Company with or into another
          corporation when the Company is not the surviving corporation, or the
          sale of all or substantially all of the Company's properties and
          assets to any other person (the "Merger") provided in which
          Warrantholder realizes a value for its shares equal to or greater than
          $2.00 per share.

     The Company shall notify the Warrantholder if the Initial Public Offering
or Merger is proposed in accordance with the terms of Subsection 8(g) hereof,
and if the Company fails to deliver such written notice, then notwithstanding
anything to the contrary in this Warrant Agreement, the rights to purchase the
Company's Preferred Stock shall not expire until the Company complies with such
notice provisions. Such notice shall also contain such details of the proposed
Initial Public Offering or Merger as are reasonable in the circumstances. If
such closing does not take place, the Company shall promptly notify the
Warrantholder that such proposed transaction has been terminated, and the
Warrantholder may rescind any exercise of its purchase rights promptly after
such notice of termination of the proposed transaction if the exercise of
Warrants occurred after the Company notified the Warrantholder that the Initial
Public Offering or Merger was proposed or if the exercise were otherwise
precipitated by such proposed Initial Public Offering or Merger. In the event of
such rescission, the Warrants will continue to be exercisable on the same terms
and conditions contained herein.

     3. EXERCISE OF THE PURCHASE RIGHTS. The purchase rights set forth in this
Warrant Agreement are exercisable by the Warrantholder, in whole or in part, at
any time, or from time to time, prior to the expiration of the term set forth in
Section 2 above, by tendering to the Company at its principal office a notice of
exercise in the form attached hereto as Exhibit I (the "Notice of Exercise"),
duly completed and executed. Upon receipt of the Notice of Exercise and the
payment of the purchase price in accordance with the terms set forth below, the
Company shall issue to the Warrantholder a certificate for the number of shares
of Preferred Stock purchased and shall execute the Notice of Exercise indicating
the number of shares which remain subject to future purchases, if any.

     Notwithstanding anything to the contrary contained in Section 2 above or
this Section 3, the Warrantholder shall either (i) exercise all outstanding
warrants by paying to the Company, by cash or check, an amount equal to the
aggregate Warrant Price of the shares being purchased, or (ii) receive shares
equal to the value

                                      -2-

(as determined below) of this Warrant by surrender of the Warrant at the
principal office of the Company together with notice of such election in which
event the Company shall issue to the Warrantholder a number of shares of
Preferred computed using the following formula:

         X =  Y(A-B)
                A

Where:   X =  the number of shares of Preferred to be issued to
              the Warrantholder.

         Y =  the number of shares of Preferred under this Warrant.

         A =  the fair market value of one share of Common.

         B =  Exercise Price.

     As used herein, current fair market value of Common Stock shall mean with
respect to each share of Common Stock the average of the closing prices of the
Company's Common Stock sold on all securities exchanges on which the Common
Stock may at the time be listed, or, if there have been no sales on any such
exchange on any day, the average of the highest bid and lowest asked prices on
all such exchanges at the end of such day, or, if on any day the Common Stock is
not so listed, the average of the representative bid and asked prices quoted in
the NASDAQ System as of 4:00 p.m., New York City time, or, if on any day the
Common Stock is not quoted in the NASDAQ System, the average of the highest bid
and lowest asked price on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of 21 days
consisting of the day as of which the current fair market value of Common Stock
is being determined and the 20 consecutive business days prior to such day. If
at any time the Common Stock is not listed on any securities exchange or quoted
in the NASDAQ System or the over-the-counter market, the current fair market
value of Preferred Stock shall be the highest price per share which the Company
could obtain from a willing buyer (not a current employee or director) for
shares of Preferred Stock sold by the Company, from authorized but unissued
shares, as determined in good faith by the Board of Directors of the Company,
unless (i) the Company shall become subject to a merger, acquisition or other
consolidation pursuant to which the Company is not the surviving party, in which
case the current fair market value of the Preferred Stock shall be deemed to be
the value received by the holders of the Company's Series B Preferred Stock for
each share of Series B Preferred Stock (or Common Stock if all such shares have
been converted into Common Stock) pursuant to the Company's Acquisition; or (ii)
the Warrantholder shall purchase such shares in conjunction with the initial
underwritten public offering of the Company's Common Stock pursuant to a
registration statement filed under the Securities Act of 1933, in which case,
the fair market value of the

                                       -3-

<PAGE>



shares of stock subject to this Warrant shall be the price at which all
registered shares are sold to the public in such offering.

     4. RESERVATION OF SHARES.

     (a) Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b) Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of exercise of the Warrant Agreement hereunder require
registration with or approval of any governmental authority under any Federal or
State law (other than any registration under the Securities Act of 1933, as then
in effect, or any similar Federal statute then enforced, or any state securities
law, required by reason of any transfer involved in such conversion), or listing
on any domestic securities exchange, before such shares may be issued upon
conversion, the Company will, at its expense and as expeditiously as possible,
use its best efforts to cause such shares to be duly registered, listed or
approved for listing on such domestic securities exchange, as the case may be.

     5. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of the
Warrantholder's rights to purchase Preferred Stock, but in lieu of such
fractional shares the Company shall make a cash payment therefor upon the basis
of the Exercise Price then in effect.

     6. NO RIGHTS AS SHAREHOLDERS. This Warrant Agreement does not entitle the
Warrantholder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrantholder's rights to purchase
Preferred Stock as provided for herein.

     7. WARRANTHOLDER REGISTRY. The Company shall maintain a registry showing
the name and address of the registered holder of this Warrant Agreement.

     8. ADJUSTMENT RIGHTS. The purchase price per share and the number of shares
of Preferred Stock purchasable hereunder are subject to adjustment from time to
time, as follows:

     (a) Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person, then, as a part of such reorganization, merger, consolidation or sale,
lawful provision shall be made so that the Warrantholder shall thereafter be
entitled to receive upon exercise

                                       -4-

<PAGE>



of its rights to purchase Preferred Stock, the number of shares of Preferred
Stock or other securities of the successor corporation resulting from such
merger or consolidation, to which a holder of the Preferred Stock deliverable
upon exercise of the right to purchase Preferred Stock hereunder would have been
entitled in such capital reorganization, merger, consolidation or sale if the
right to purchase such Preferred Stock hereunder had been exercised immediately
prior to such capital reorganization, merger, consolidation or sale. In any such
case, appropriate adjustment (as determined in good faith by the Company's Board
of Directors) shall be made in the application of the provisions of this Warrant
Agreement with respect to the rights and interest of the Warrantholder after the
reorganization, merger, consolidation or sale to the end that the provisions of
this Warrant Agreement (including adjustments of the Exercise Price and number
of shares of Preferred Stock purchasable pursuant to the terms and conditions of
this Warrant Agreement) shall be applicable after that event, as near as
reasonably may be, in relation to any shares deliverable after that event upon
the exercise of the Warrantholder's rights to purchase Preferred Stock pursuant
to this Warrant Agreement.

     (b) Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares. If the Company at any time shall
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d) Stock Dividends. If the Company at any time shall pay a dividend
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the date of
determination of stockholders entitled to receive such dividend or distribution,
to that price determined by multiplying the Exercise Price in effect immediately
prior to such date of determination by a fraction (i) the numerator of which
shall be the total number of all shares of the Company's stock outstanding
immediately prior to such dividend or distribution, and (ii) the denominator of
which shall be the total number of all shares of the Company's stock outstanding
immediately after such dividend or distribution. The Warrantholder shall
thereafter be entitled to purchase, at the Exercise Price resulting from such
adjustment, the number of shares of Preferred Stock (calculated to the nearest
whole share) obtained by

                                       -5-

<PAGE>



multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of shares of Preferred Stock issuable upon the exercise hereof
immediately prior to such adjustment and dividing the product thereof by the
Exercise Price resulting from such adjustment.

     (e) Issuance of Shares at Other Than Exercise Price. If the Company should
issue shares of its stock or any other equity security at a price per share less
than the Exercise Price in effect immediately prior to such issuance, then the
Exercise Price shall be adjusted by dividing (i) the sum of (A) the total number
of shares of the Company's stock outstanding immediately prior to such issuance
multiplied by the then effective Exercise Price and (B) the value of the
consideration received by the Company upon such issuance of such shares, by (ii)
the total number of shares of the Company's stock outstanding immediately after
such issuance. The Warrantholder shall thereafter be entitled to purchase, at
the Exercise Price resulting from such adjustment, the number of shares of
Preferred Stock (calculated to the nearest whole share) obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of shares of Preferred Stock issuable upon the exercise hereof immediately prior
to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment. For the purposes of this paragraph (e), the
issuance of securities convertible into or exercisable for the Preferred Stock
shall be deemed the issuance of the number of shares of Preferred Stock into
which such securities are convertible or for which such securities are
exercisable, and the consideration received for such securities shall be deemed
to include the minimum aggregate amount payable upon conversion or exercise of
such securities. In the event the right to convert or exercise such securities
expires unexercised, the Exercise Price of shares issuable upon the exercise
hereof shall be readjusted accordingly.

     (f) Right to Purchase Additional Stock. If, for any reason, the total
Warrantholder's cost of equipment leased pursuant to the Leases should exceed
$500,000, Warrantholder shall have the right to purchase from the Company, at
the Exercise Price per share specified in section 1 (which price may be subject
to adjustment from time to time as provided for in this Section 8), an
additional number of shares, which number shall be determined by (i) multiplying
the amount by which the Warrantholder's total equipment cost exceeds $500,000 by
12%, and (ii) dividing the product thereof by the Exercise Price per share
referenced above.

     (g) Notice of Adjustments. In the event that: (i) the Company shall declare
any dividend or distribution upon its stock, whether in cash, property, stock or
other securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any capital
reorganization, reclassification, consolidation, merger or sale of all or
substantially all of the Company's assets; or (iv) there shall be any voluntary
or involuntary dissolution,

                                       -6-

<PAGE>



liquidation or winding up of the Company; then, in connection with each such
event, the Company shall send to the Warrantholder:

          (i) At least 20 days' prior written notice of the date on which the
     books of the Company shall close or a record shall be taken for such
     dividend, distribution, subscription rights (specifying the date on which
     the holders of Preferred Stock shall be entitled thereto) or for
     determining rights to vote in respect of such capital reorganization,
     reclassification, consolidation, merger or sale of all or substantially all
     of the Company's assets, dissolution, liquidation or winding up; and

         (ii) In the case of any such capital reorganization, reclassification,
     consolidation, merger or sale of all or substantially all of the Company's
     assets, dissolution, liquidation or winding up, at least 20 days' prior
     written notice of the date when the same shall take place (and specifying
     the date on which the holders of Preferred Stock shall be entitled to
     exchange their Preferred Stock for securities or other property deliverable
     upon such capital reorganization, reclassification, consolidation, merger
     or sale of all or substantially all of the Company's assets, dissolution,
     liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (h) Registration and Listing. The Company will take all such actions as may
be necessary to assure that all shares of Preferred Stock issuable pursuant to
this Warrant Agreement may be so issued without violation of any applicable law
or regulation or any requirements of any domestic stock exchange (except for
official notice of issuance, which will be immediately transmitted by the
company upon issuance) upon which shares of Preferred Stock or other shares of
the same class may be listed. The Company will not take any action which will
result in any adjustment of the number of shares of Preferred Stock issuable
upon exercise of this Warrant Agreement if the total number of shares of
Preferred Stock issuable after such action upon exercise of the Warrant
Agreement then outstanding, together with the total number of shares of
Preferred Stock then outstanding, would exceed the total number of shares of
Preferred Stock then authorized and not reserved for any purpose other than the
purpose of issue upon exercise of the Warrant Agreement.

     9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a) Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will be
validly issued, fully paid and non-assessable, and will be free of any taxes,

any) and Shareholder meetings the Company's inception through May 16, 1991. The
issuance of certificates for shares of Preferred Stock upon exercise of the
Warrant Agreement shall be made without charge to the Warrantholder for any

connection with such exercise and the related issuance of shares of Preferred
Stock; provided that the Company shall not be required to pay any tax which may
be payable in respect of any transfer involved and the issuance and delivery of
any certificate in a name other than that of the Warrantholder. The Company will
not close its books against the transfer of the Warrant Agreement or of any
share of Preferred Stock issued or issuable upon exercise of the Warrant and any
agreement in any manner which interferes with the timely exercise of the
Warrant.

     (b) Due Authority. The execution and delivery by the Company of the Leases,
and this Warrant Agreement and the performance of all obligations of the Company
thereunder and hereunder, including the issuance to Warrantholder of the right
to acquire the shares of Preferred Stock set forth in Section 1 above (which
number of shares may be from time to time adjusted pursuant to the terms of
Section 8 above) have been duly authorized by all necessary corporate action on
the part of the Company, and the Leases and this Warrant Agreement are not
inconsistent with the Company's Certificate of Incorporation or By-Laws, do not
contravene any law or governmental rule, regulation or order applicable to it,
do not and will not contravene any provision of, or constitute a default under,
any indenture, mortgage, contract or other instrument to which it is a party or
by which it is bound, and the Leases and this Warrant Agreement constitute
legal, valid and binding agreements of the Company, enforceable in accordance

the execution, delivery and performance by the Company of its obligations under
this Warrant Agreement.

     (d) Litigation. There are no actions, suits, audits, investigations or
proceedings pending or, to the knowledge of the Company, threatened against or

on the ability of the Company to perform its obligations under the Leases and
this Warrant Agreement.

     outstanding Preferred Stock is convertible into Common Stock on a share for
     share basis.

         (ii) The Company has reserved (A) 1,100,000 shares of Common Stock for
     issuance under its Stock Option Plan, under which 640,000 options are
     outstanding except for the warrant granted to Sierra Ventures to purchase
     1,100,000 shares of Series C Preferred Stock at a price of $1.50. There are
     no other options, warrants, conversion privileges or other rights presently
     outstanding to purchase or otherwise acquire any authorized but unissued

31, 1990, together with the report thereon of its independent public
accountants, and its unaudited Balance Sheet and Statement of Income for the
five (5) month period ending may 31, 1991 (the "Financial Statements"). The

periods indicated therein are true and correct in all material aspects, subject
as to the Balance Sheet and Statement of Income for the five (5) month period
then ending May 31, 1991, to normal year-end audit adjustments. Since May 31,
1991, there has been no change in the assets, liabilities, financial condition
or operations of the Company from that reflected in the Financial Statements

copyrights necessary for the operation of its business as now conducted, with no
known infringement of, or conflict with, the rights of others.

     (j) Employee Contracts. To the best of the Company's knowledge, no employee
of the Company is in violation of any material term of any employment contract,
patent disclosure agreement or any other contract or agreement relating to the
relationship of any such employee with the Company or any prior employer because
of the nature of the business conducted by the Company.

     (k) Insurance. The Company has in full force and effect insurance policies,

rights granted in the Warrant Purchase Agreement dated August 14, 1990, and
those rights granted in this Warrant Agreement, the Company is not, pursuant to
the terms of any other agreement currently in existence, under any obligation to
register under the 1933 Act, any of its presently outstanding securities or any
of its securities which may hereafter be issued.

     (m) Exempt Transaction. Subject to the accuracy of the Warrantholder's
representations in Section 10 hereof, the issuance of the Preferred Stock upon

qualification requirements of the Delaware Corporate Securities Law.

     (n) Compliance with Rule 144. At the written request of the Warrantholder,
who proposes to sell Preferred Stock issuable upon the exercise of the Warrant
in compliance with Rule 144 promulgated by the Securities and Exchange
Commission under the 1933 Act, the Company shall furnish to the Warrantholder,
within ten days after receipt of such request, a written statement confirming
the Company's compliance with the filing requirements of the Securities and
Exchange Commission as set forth in such Rule, as such Rule may be amended from
time to time.

     (o) No Events of Default, Material Contracts. All material contracts,

effect in all material respects, and are valid, binding and enforceable by the
Company in accordance with their respective terms, subject to the effect of
applicable bankruptcy and other similar laws affecting the rights of creditors
generally, and rules of law concerning equitable remedies and no event of

any other transaction contemplated thereby.

     (q) Untrue, Misleading Statements. No representation or warranty of the
Company contained in the Leases, and this Warrant Agreement or any certificate

connection with the transactions contemplated thereby (when read together)
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements contained therein not misleading.

     (r) Indebtedness to Employees and Shareholders. The Company is not indebted
to any employee, shareholder, officer or director of the Company, and no such

     10. REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER. This Warrant
Agreement has been entered into by the Company in reliance upon the following
representations and covenants of the Warrantholder, which by its execution
hereof the Warrantholder hereby confirms:

     (a) Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b) Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of the Warrantholder's rights contained herein is
not registered under the 1933 Act or qualified under applicable state securities
laws on the ground that the issuance contemplated by this Warrant Agreement will
be exempt from the registration and qualifications requirements thereof, and
(ii) that the Company's reliance on such exemption is predicated on the
representations set forth in this Section 10.

     (c) Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred

                                      -12-

<PAGE>



without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. Whenever the restrictions
imposed hereunder shall terminate, as hereinabove provided, the Warrantholder or
holder of a share of Preferred Stock then outstanding as to which such
restrictions have terminated shall be entitled to receive from the Company,
without expense to such holder, one or more new certificates for the Warrant or
for such shares of Preferred Stock not bearing any restrictive legend.

     (d) Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment and has the ability to bear the economic risks of its
investment.

     (e) Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1933 Act, or file reports pursuant to Section 15(d), of the
Securities Exchange Act of 1934 (the "1934 Act"), or if a registration statement
covering the securities under the 1933 Act is not in effect when it desires to
sell (i) the rights to purchase Preferred Stock pursuant to this Warrant
Agreement, or (ii) the Preferred Stock issuable upon exercise of the right to
purchase, it may be required to hold such securities for an indefinite period.
The Warrantholder also understands that any sale of its rights of the
Warrantholder to purchase Preferred Stock or Preferred Stock which might be made

accordance with the terms and conditions of that Rule.

     11. Registration Rights. Warrantholder and Company agree that all shares of
Preferred Stock subject to the Warrant Agreement shall have the same
registration rights and be subject to the same terms and conditions with respect
to the registration and sale of such stock as possessed by the Series B
Preferred Shareholders as provided for in the Second Investors Rights Agreement
dated April 15, 1991, by and among the Company and those certain Purchasers
identified therein, attached hereto as Exhibit II.

     12. TRANSFERS. Subject to the terms and conditions contained in Section 10
hereof, this Warrant Agreement and all rights hereunder are transferable in
whole or in part by the Warrantholder and any successor transferee, provided,
however, that in no event shall the number of transfers of the rights and
interests in all of the Warrants exceed three (3) transfers. The transfer shall
be recorded on the books of the Company upon receipt by the Company of a notice
of transfer in the form attached hereto as Exhibit III (the "Transfer Notice"),
at its principal offices and the payment to the Company of all transfer taxes
and other governmental charges imposed on such transfer.

                                   EXHIBIT II


                        SECOND INVESTOR RIGHTS AGREEMENT


     This Agreement is made as of the ____ day of April, 1991, by and among
Digitran Corporation, a Delaware corporation (the "Company") and the undersigned
investors (collectively, the "Investors").

                                 R E C I T A L S

     A. The Company and certain of the Investors are parties to an Investor
Rights Agreement dated April _, 1991 (the "Investor Rights Agreement"), which
grants such Investors certain registration rights and certain other investor
rights.

     B. The Company desires to enter into an agreement with certain purchasers
(collectively, the "Proposed Agreement") that will provide, among other things,
for the sale and issuance of up to 1,600,000 shares of Series B Preferred Stock
of the Company at $1.00 per share (the "Additional Shares").

     C. Pursuant to Section 5.5 of the Investor Rights Agreement, the Company
must obtain the approval of the holders of a majority of the "Registrable
Securities" (as defined as section 3.1(b) of the Investor Rights Agreement), and
a majority of the holders of the Common Stock of the Company issued or issuable
upon conversion of the Preferred Stock held by the parties to the Investor
Rights Agreement, not including Common Stock held by Martin Ellis, Jeffrey
Kurland, Jerry Siegan and Marshall Ellis, in order to grant registration rights
and certain other investor rights with respect to the Additional Shares or in
order to amend any provision of the Investor Rights Agreement.

     D. Certain of the Investors are holders of a majority of the currently
outstanding Registrable Securities (as defined in Section 3.1(b) of the Investor
Rights Agreement) and holders of a majority of the Common Stock of the Company
issued or issuable upon conversion of the Preferred Stock held by the parties to
the Investor Rights Agreement, not including Common Stock held by Martin Ellis,
Jeffrey Kurland, Jerry Siegan and Marshall Ellis.

     NOW, THEREFORE, in consideration of good and valuable consideration, the
receipt of which is hereby acknowledged, the undersigned hereby agree as
follows:

     1. Consent to Grant of Registration Rights. Pursuant to Section 5.5 of the
Investor Rights Agreement, certain of the Investors, being the holders of a
majority of the currently outstanding Registrable Securities (as defined in
Section 3.1(b)


<PAGE>



of the Investor Rights Agreement) hereby consent to the granting of registration
rights to the purchasers of the Additional Shares.

     2. Amendment of Investor Rights Agreement. Effective upon the first
issuance and sale of the Additional Shares, the prior Investor Rights Agreement
shall be terminated and of no further force and effect and the Investors agree
to be bound by the provisions hereof.

     3. Registration Rights. The Company covenants and agrees as follows:

     3.1 Definitions. For purposes of this Section 3:

          a. The term "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;

          b. The term "Registrable Securities" means(1) the Common Stock
     issuable or issued upon conversion of the outstanding Series A Preferred
     Stock, (2) the Common Stock issuable or issued upon conversion of the
     Series B Preferred Stock sold pursuant to the Proposed Agreement, (3) the
     Common Stock issuable or issued upon conversion of the Series C Preferred
     Stock issued or issuable upon exercise of the outstanding Series C Warrant,
     (4) only for purposes of Sections 3.3, 3.7 and 3.10, the Founders Stock (as
     defined below), and (5) any Common Stock of the Company issued as (or
     issuable upon the conversion or exercise of any other warrant, right or
     other security which is issued as) a dividend or other distribution with
     respect to, or in exchange for or in replacement of such Preferred Stock,
     Warrants, Founders Stock or Common Stock, excluding in all cases, however,
     any Registrable Securities sold by a person in a transaction in which his
     rights under this Section 3 are not assigned;

          c. The number of shares of "Registrable Securities then outstanding"
     shall be determined by the number of shares of Common Stock outstanding
     which are, and the number of shares of Common Stock issuable pursuant to
     then exercisable or convertible securities which are, Registrable
     Securities.

          d. The term "Holder" means any person owning or having the right to
     acquire Registrable Securities or any assignee thereof in accordance with
     Section 3.13 hereof; and

          e. The term "Form S-3" means such form under the Act as in effect on
     the date hereof or any registration form under the Act subsequently adopted
     by the Securities and Exchange

                                       2.

<PAGE>



     Commission ("SEC") which permits inclusion or incorporation of substantial
     information by reference to other documents filed by the company with the
     SEC.

          f. The term "Founders Stock" shall mean the shares of Common Stock
     held by the individuals as set forth on Exhibit C to the Proposed
     Agreement.

     3.2 Request for Registration.

          a. If the Company shall receive at any time after the earlier of (i)
     August 13, 1992, or (ii) three (3) months after the effective date of the
     first registration statement for a public offering of securities of the
     Company (other than a registration statement relating either to the sale of
     securities to employees of the Company pursuant to a stock option, stock
     purchase or similar plan or a SEC Rule 145 transaction), a written request
     from the Holders of a majority of the Registrable Securities then
     outstanding that the Company file a registration statement under the Act
     covering the registration of Registrable Securities then the Company shall,
     within ten (10) days of the receipt thereof, give written notice of such
     request to all Holders and shall, subject to the limitations of subsection
     3.2(b), effect as soon as practicable, and in any event shall use its best
     efforts to effect within 120 days of the receipt of such request, the
     registration under the Act of all Registrable Securities which the Holders
     request to be registered within twenty (20) days of the mailing of such
     notice by the Company in accordance with paragraph 5.7.

          b. If the Holders initiating the registration request hereunder
     ("Initiating Holders") intend to distribute the Registrable Securities
     covered by their request by means of an underwriting, they shall so advise
     the Company as a part of their request made pursuant to this Section 3.2
     and the Company shall include such information in the written notice
     referred to in subsection 3.2(a). The underwriter will be selected by the
     Company and a majority in interest of the Initiating Holders and shall be
     reasonably acceptable to the Company. In such event, the right of any
     Holder to include his Registrable Securities in such registration shall be
     conditioned upon such Holder's participation in such underwriting and the
     inclusion of such Holder's Registrable Securities in the underwriting
     (unless otherwise mutually agreed by a majority in interest of the
     Initiating Holders and such Holder) to the extent provided herein. All
     Holders proposing to distribute their securities through such underwriting
     shall (together with the Company as provided in subsection 3.4(e)) enter
     into an underwriting agreement in customary form with the underwriter or
     underwriters selected for such underwriting by a majority in interest of
     the Initiating Holders. Notwithstanding any other provision of this Section
     3.2, if the underwriter advises the Initiating Holders in writing that
     marketing factors require a limitation of the number of shares to be
     underwritten, then the Initiating Holders shall so advise all Holders of
     Registrable Securities which would otherwise be underwritten pursuant
     hereto, and the number of shares of Registrable Securities that may be

                                       3.

<PAGE>



     included in the underwriting shall be allocated among all Holders thereof,
     including the Initiating Holders, in proportion (as nearly as practicable)
     to the amount of Registrable Securities of the Company owned by each
     Holder; provided, however, that the number of shares of Registrable
     Securities to be included in such underwriting shall not be reduced unless
     all other securities are first entirely excluded from the underwriting.

          c. The Company is obligated to effect only two (2) such registrations
     pursuant to this Section 3.2.

          d. Notwithstanding the foregoing, if the Company shall furnish to
     Holders requesting a registration statement pursuant to this Section 3.2, a
     certificate signed by the President of the Company stating that in the good
     faith judgment of the Board of Directors of the Company, it would be
     seriously detrimental to the Company and its shareholders for such
     registration statement to be filed and it is therefore essential to defer
     the filing of such registration statement, the Company shall have the right
     to defer taking action with respect to such filing for a period of not more
     than 60 days after receipt of the request of the Initiating Holders;
     provided, however, that the Company may not utilize this right more than
     once in any twelve month period.

     3.3 Company Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for shareholders other than the Holders) any of its stock or
other securities under the Act in connection with the public offering of such
securities solely for cash (other than a registration relating solely to the
sale of securities to participants in a Company stock plan, or a registration on
any form which does not include substantially the same information as would be
required to be included in a registration statement covering the sale of the
Registrable Securities), the Company shall, at such time, promptly give each
Holder written notice of such registration. Upon the written request of each
Holder given within twenty (20) days after mailing of such notice by the Company
in accordance with Section 5.7, the Company shall, subject to the provisions of
Section 3.8, cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested to be registered.

     3.4 Obligations of the Company. Whenever required under this Section 3 to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

          a. Prepare and file with the SEC a registration statement with respect
     to such Registrable Securities and use its best efforts to cause such
     registration statement to become effective, and, upon the request of the
     Holders of a majority of the Registrable Securities registered thereunder,
     keep such registration statement effective for up to one hundred twenty
     (120) days.


                                       4.

<PAGE>



          b. 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 Holders 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 its best 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 Holders,
     provided that the Company 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.

          e. In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering. Each Holder
     participating in such underwriting shall also enter into and perform its
     obligations under such an agreement.

          f. Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act of the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

          g. Use its best efforts to furnish, at the request of any Holder
     requesting registration of Registrable Securities pursuant to this Section
     3, on the date that such Registrable Securities are delivered to the
     underwriters for sale in connection with a registration pursuant to this
     Section 3, if such securities are being sold through underwriters, or, if
     such securities are not being sold through underwriters, on the date that
     the registration statement with respect to such securities becomes
     effective, (i) an opinion, dated such date, of the counsel representing the
     Company for the purposes of such registration, in form and substance as is
     customarily given to underwriters in an underwritten public offering,
     addressed to the underwriters, if any, and to the Holders requesting
     registration of Registrable Securities and (ii) a letter dated such date,
     from the independent certified public accountants of the Company, in form
     and substance as is customarily given by independent certified public
     accountants to underwriters in an underwritten public offering, addressed
     to the underwriters, if

                                       5.

<PAGE>



     any, and to the Holders requesting registration of Registrable Securities.

     3.5 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 3 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

     3.6 Expenses of Demand Registration. All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to Section 3.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company, and the reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company; provided, however, that the Company shall not be required to pay for
any expenses of any registration proceeding begun pursuant to Section 3.2 if the
registration request is subsequently withdrawn at the request of the Holders of
a majority of the Registrable Securities to be registered (in which case all
Participating Holders shall bear such expenses), unless the Holders of a
majority of the Registrable Securities agree to forfeit their right to one
demand registration pursuant to Section 3.2; provided, further, however, that if
at the time of such withdrawal, the Holders have learned of a material adverse
change in the condition, business, or prospects of the Company from that known
to the Holders at the time of their request and have withdrawn the request with
reasonable promptness following disclosure by the Company of such material
adverse change, then the Holders shall not be required to pay any of such
expenses and shall retain their rights pursuant to Section 3.2.

     3.7 Expenses of Company Registration. The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
3.3 for each Holder (which right may be assigned as provided in Section 3.13),
including (without limitation) all registration, filing, and qualification fees,
printers and accounting fees relating or apportionable thereto, and the fees and
disbursements of one counsel for the selling Holders selected by them, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

     3.8 Underwriting Requirements. In connection with any offering involving an
underwriting of shares of the Company's capital stock, the Company shall not be
required under Section 3.3 to include any of the Holders' securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled to select the underwriters), and then only

                                       6.

<PAGE>



in such quantity as the underwriters determine in their sole discretion will
not, jeopardize the success of the offering by the Company. If the total amount
of securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities sold other than by
the Company that the underwriters determine in their sole discretion is
compatible with the success of the offering, then the Company shall be required
to include in the offering only that number of such securities, including
Registrable Securities, which the underwriters determine in their sole
discretion will not jeopardize the success of the offering (the securities so
included to be apportioned pro rata among the selling shareholders according to
the total amount of securities entitled to be included therein owned by each
selling Shareholder or in such other proportions as shall mutually be agreed to
by such selling shareholders) but in no event shall (i) the amount of securities
of the selling Holders included in the offering be reduced below thirty percent
(30%) of the total amount of securities included in such offering, unless such
offering is the initial public offering of the Company's securities in which
case the selling shareholders may be excluded if the underwriters make the
determination described above and no other shareholder's securities are included
or (ii) notwithstanding (i) above, any shares being sold by a shareholder
exercising a demand registration right similar to that granted in Section 3.2 be
excluded from such offering. For purposes of the preceding parenthetical
concerning apportionment, for any selling shareholder which is a holder of
Registrable Securities and which is a partnership or corporation, the partners,
retired partners and shareholders of such holder, or the estates and family
members of any such partners and retired partners and any trusts for the benefit
of any of the foregoing persons shall be deemed to be a single "selling
shareholder", and any pro-rata reduction with respect to such "selling
shareholder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"selling shareholder", as defined in this sentence.

     3.9 Delay of Registration. No Holder shall have any right to obtain or seek
an injunction restraining or otherwise delaying any such registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 3.

     3.10 Indemnification. In the event any Registrable Securities are included
in a registration statement under this Section 3:

          a. To the extent permitted by law, the Company will indemnify and hold
     harmless each Holder, any underwriter (as defined in the Act) for such
     Holder and each person, if any, who controls such Holder or underwriter
     within the meaning of the Act or the Securities Exchange Act of 1934, as
     amended (the "1934 Act"), against any losses, claims, damages, or
     liabilities (joint or several) to which they may become subject under the
     Act, or the 1934 Act or other federal or state law, insofar as such losses,

                                       7.

<PAGE>



     claims, damages, or liabilities (or actions in respect thereof) 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) the
     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 Company of
     the Act, the 1934 Act, any state securities law or any rule or regulation
     promulgated under the Act, or the 1934 Act or any state securities law; and
     the Company will pay to each such Holder, underwriter or controlling
     person, as incurred, any legal or other expenses reasonably incurred by
     them in connection with investigating or defending any such loss, claim,
     damage, liability, or action; provided, however, that the indemnity
     agreement contained in this subsection 3.10(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 the Company (which
     consent shall not be unreasonably withheld), nor shall the Company be
     liable in any such case for any such loss, claim, damage, liability, or
     action to the extent that it arises out of or is based upon a Violation
     which occurs in reliance upon and in conformity with written information
     furnished expressly for use in connection with such registration by any
     such Holder, underwriter or controlling person.

          b. To the extent permitted by law, each selling Holder will indemnify
     and hold harmless the Company, each of its directors, each of its officers
     who has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, 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 Violation, in each case to the extent (and only to the extent) that
     such Violation occurs in reliance upon and in conformity with written
     information furnished by such Holder expressly for use in connection with
     such registration; and each such Holder will pay, as incurred, any legal or
     other expenses reasonably incurred by any person intended to be indemnified
     pursuant to this subsection 3.10(b), in connection with investigating or
     defending any such loss, claim, damage, liability, or action; provided,
     however, that the indemnity agreement contained in this subsection 3.10(b)
     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 the Holder, which consent shall not be unreasonably withheld;
     provided, that, in no event shall any indemnity under this subsection
     3.10(b) exceed the gross proceeds from the offering received by such
     Holder.

                                       8.

<PAGE>




          c. Promptly after receipt by an indemnified party under this Section
     3.10 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
     3.10, 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. The failure to deliver written notice to the
     indemnifying party within a reasonable time of the commencement of any such
     action, if prejudicial to its ability to defend such action, shall relieve
     such indemnifying party of any liability to the indemnified party under
     this Section 3.10, but the omission so to deliver written notice to the
     indemnifying party will not relieve it of any liability that it may have to
     any indemnified party otherwise than under this Section 3.10.

          d. If the indemnification provided for in subsection (a) or (b) of
     this Section 3.10 is held by a court of competent jurisdiction to be
     unavailable to an indemnified party, then each indemnifying party under any
     such subsection, in lieu of indemnifying such indemnified party thereunder,
     hereby agrees to contribute to the amount paid or payable by such
     indemnified party 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. Notwithstanding the foregoing, the amount
     any Holder of Registrable Securities shall be obligated to contribute
     pursuant to this subsection (d) shall be limited to an amount equal to the
     net proceeds from the offering received by such holder.

          e. The obligations of the Company and Holders under this Section 3.10
     shall survive the completion of any offering of Registrable Securities in a
     registration statement under this Section 3, and otherwise.

     3.11 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration or pursuant to
a registration on Form S-3, the Company agrees to:

          a. make and keep public information available, as those terms are
     understood and defined in SEC Rule 144, at all times after ninety (90) days
     after the effective date of the first

                                       9.

<PAGE>



     registration statement filed by the Company for the offering of its
     securities to the general public;

          b. take such action, including the voluntary registration of its
     Common Stock under Section 12 of the 1934 Act, as is necessary to enable
     the Holders to utilize Form S-3 for the sale of their Registrable
     Securities, such action to be taken as soon as practicable after the end of
     the fiscal year in which the first registration statement filed by the
     Company for the offering of its securities to the general public is
     declared effective;

          c. file with the SEC in a timely manner all reports and other
     documents required of the Company under the Act and the 1934 Act; and

          d. furnish to any Holder, so long as the Holder owns any Registrable
     Securities, forthwith upon request (i) a written statement by the Company
     that it has complied with the reporting requirements of SEC Rule 144 (at
     any time after ninety (90) days after the effective date of the first
     registration statement filed by the Company), the Act and the 1934 Act (at
     any time after it has become subject to such reporting requirements), or
     that it qualifies as a registrant whose securities may be resold pursuant
     to Form S-3 (at any time after it so qualifies), (ii) a copy of the most
     recent annual or quarterly report of the Company and such other reports and
     documents so filed by the Company, and (iii) such other information as may
     be reasonably requested in availing any Holder of any rule or regulation of
     the SEC which permits the selling of any such securities without
     registration or pursuant to such form.

     3.12 Form S-3 Registration. In case the Company shall receive from Holders
of at least twenty percent (20%) of the Registrable Securities then outstanding
a written request or requests that the Company effect a registration on Form S-3
and any related qualification or compliance with respect to all or a part of the
Registrable Securities owned by such Holder or Holders, the Company will:

          a. promptly give written notice of the proposed registration, and any
     related qualification or compliance, to all other Holders; and

          b. as soon as practicable, effect such registration and all such
     qualifications and compliances as may be so requested and as would permit
     or facilitate the sale and distribution of all or such portion of such
     Holder's or Holders' Registrable Securities as are specified in such
     request, together with all or such portion of the Registrable Securities of
     any other Holder or Holders joining in such request as are specified in a
     written request given within fifteen (15) days after receipt of such
     written notice from the Company; provided, however, that the Company shall
     not be obligated to effect any such registration, qualification or
     compliance, pursuant to this section 3.12: (1) if Form S-3 is not available
     for such offering by the Holders; (2) if

                                       10.

<PAGE>



     the Holders, together with the holders of any other securities of the
     Company entitled to inclusion in such registration, propose to sell
     Registrable Securities and such other securities (if any) at an aggregate
     price to the public (net of any underwriters' discounts or commissions) of
     less than $250,000; (3) if the Company shall furnish to the Holders a
     certificate signed by the President of the Company stating that in the good
     faith judgment of the Board of Directors of the Company, it would be
     seriously detrimental to the Company and its shareholders for such Form S-3
     Registration to be effected at such time, in which event the Company shall
     have the right to defer the filing of the Form S-3 registration statement
     for a period of not more than sixty (60) days after receipt of the request
     of the Holder or Holders under this Section 3.12; provided, however, that
     the Company shall not utilize this right more than once in any twelve month
     period; (4) if the Company has, within the twelve (12) month period
     preceding the date of such request, already effected two registrations on
     Form S-3 for the Holders pursuant to this Section 3.12; or (5) in any
     particular jurisdiction in which the Company would be required to qualify
     to do business or to execute a general consent to service of process in
     effecting such registration, qualification or compliance.

          c. Subject to the foregoing, the Company shall file a registration
     statement covering the Registrable Securities and other securities so
     requested to be registered as soon as practicable after receipt of the
     request or requests of the Holders. All expenses incurred in connection
     with a registration requested pursuant to Section 3.12, including (without
     limitation) all registration, filing, qualification, printer's and
     accounting fees and the reasonable fees and disbursements of counsel for
     the selling Holder or Holders and counsel for the Company, but excluding
     any underwriters' discounts or commissions associated with Registrable
     Securities, shall be borne pro rata by the Holder or Holders participating
     in the Form S-3 Registration. Registrations effected pursuant to this
     Section 3.12 shall not be counted as demands for registration or
     registrations effected pursuant to Sections 3.2 or 3.3, respectively.

     3.13 Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to this Section 3 may be assigned (but
only with all related obligations) by a Holder to a transferee or assignee of
such securities, provided the Company is, within a reasonable time after such
transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act.

     3.14 Limitations on Subsequent Registration Rights. From and after the date
of this Agreement, the Company shall not, without the prior written consent of
the Holders of a majority of the outstanding Registrable Securities, enter into
any agreement with

                                       11.

<PAGE>



any holder or prospective holder of any securities of the Company which would
allow such holder or prospective holder (a) to include such securities in any
registration filed under Section 3.2 hereof, unless under the terms of such
agreement, such holder or prospective holder may include such securities in any
such registration only to the extent that the inclusion of his securities will
not reduce the amount of the Registrable Securities of the Holders which is
included or (b) to make a demand registration which could result in such
registration statement being declared effective prior to the earlier of either
of the dates set forth in subsection 3.2(a) or within one hundred twenty (120)
days of the effective date of any registration effected pursuant to Section 3.2.

     3.15 "Market Stand-Off" Agreement. Each Investor hereby agrees that, during
the period, of duration specified by the Company and an underwriter of Common
Stock or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Act, it shall not, to the
extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it at any time during such period except Common Stock included in such
registration; provided, however, that:

          a. such agreement shall be applicable only to the first such
     registration statement of the Company which covers Common Stock (or other
     securities) to be sold on its behalf to the public in an underwritten
     offering; and

          b. all officers and directors of the Company and all other persons
     with registration rights (whether or not pursuant to this Agreement) enter
     into similar agreements.

     In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of each
Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

     3.16 Termination of Registration Rights. No Holder shall be entitled to
exercise any right provided for in this Section 3 after seven (7) years
following the consummation of the sale of securities pursuant to a registration
statement filed by the Company under the Act in connection with the initial firm
commitment underwritten offering of its securities to the general public.

     4. Covenants of the Company. This Section 4 shall not apply to Martin
Ellis, Jeffrey Kurland, Jerry Siegan and Marshall Ellis, (the holders of
Founders Stock as listed on Exhibit C to the Proposed Agreement), or transferees
thereof.


                                       12.

     4.1 Delivery of Financial Statements. The Company shall deliver to each
Investor:

          a. as soon as practicable, but in any event within ninety (90) days
     after the end of each fiscal year of the Company, an income statement for
     such fiscal year, a balance sheet of the Company and statement of
     shareholder's equity as of the end of such year, and a schedule as to the
     sources and applications of funds for such year, such year-end financial
     reports to be in reasonable detail, prepared in accordance with generally
     accepted accounting principles ("gaap"), and audited and certified by
     independent public accountants of nationally recognized standing selected
     by the Company;

          b. within thirty (30) days of the end of each month, an unaudited
     income statement and schedule as to the sources and application of funds
     and balance sheet for and as of the end of such month, in reasonable
     detail;

          c. as soon as practicable, but in any event thirty (30) days prior to
     the end of each fiscal year, a budget and business plan for the next fiscal
     year, prepared on a monthly basis, including balance sheets and sources and
     applications of funds statements for such months and, as soon as prepared,
     any other budgets or revised budgets prepared by the Company;

          d. with respect to the financial statements called for in subsection
     (b) of this Section 4.1, an instrument executed by the Chief Financial
     officer or President of the Company and certifying that such financials
     were prepared in accordance with gaap consistently applied with prior
     practice for earlier periods (with the exception of footnotes that may be
     required by gaap) and fairly present the financial condition of the Company
     and its results of operation for the period specified, subject to year-end
     audit adjustment;

          e. such other information relating to the financial condition,
     business, prospects or corporate affairs of the Company as the Investor or
     any assignee of the Investor may from time to time request, provided,
     however, that the Company shall not be obligated under this subsection (e)
     or any other subsection of Section 4.1 to provide information which it
     deems in good faith to be a trade secret or similar confidential
     information.

     4.2 Inspection. The Company shall permit each Investor, at such Investor's
expense, to visit and inspect the Company's properties, to examine its books of
account and records and to discuss the Company's affairs, finances and accounts
with its officers, all at such reasonable times as may be requested by such
Investor; provided, however, that the Company shall not be obligated pursuant to
this Section 4.2 to provide access to any information which it reasonably
considers to be a trade secret or similar confidential information.


                                       13.

<PAGE>



     4.3 Termination of Information and Inspection Covenants. The covenants set
forth in subsections 4.1(b), (c) and (e) and Section 4.2 shall terminate as to
each Investor and be of no further force or effect when the sale of securities
pursuant to a registration statement filed by the Company under the Act in
connection with the firm commitment underwritten offering of its securities to
the general public is consummated or when the Company first becomes subject to
the periodic reporting requirements of Sections 12(g) or 15(d) of the 1934 Act,
whichever event shall first occur.

     4.4 Right of First Offer. Subject to the terms and conditions specified in
this paragraph 4.4, the Company hereby grants to the Investor (as hereinafter
defined) a right of first offer with respect to future sales by the Company of
its Shares (as hereinafter defined). For purposes of this Section 4.4, Investor
includes any general partners and affiliates of an Investor. The Investor shall
be entitled to apportion the right of first offer hereby granted it among itself
and its partners and affiliates in such proportions as it deems appropriate.

     Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for any shares of, any class of its capital
stock ("Shares"), the Company shall first make an offering of such Shares to the
Investor in accordance with the following provisions:

          a. The Company shall deliver a notice by certified mail ("Notice") to
     the Investor stating (i) its bona fide intention to offer such Shares, (ii)
     the number of such Shares to be offered, and (iii) the price and terms, if
     any, upon which it proposes to offer such Shares.

          b. By written notification received by the Company, within twenty (20)
     calendar days after receipt giving of the Notice, the Investor may elect to
     purchase or obtain, at the price and on the terms specified in the Notice,
     up to that portion of such Shares which equals the proportion that the
     number of shares of Common Stock issued and held, or issuable upon
     conversion of the Preferred Stock then held, by such Investor bears to the
     total number of shares of Common Stock of the Company then outstanding,
     assuming full conversion of all then-outstanding Preferred Stock. The
     Company shall promptly, in writing, inform the Investor which purchases all
     the shares available to it ("Fully-?Exercising Investor") of any other
     Investor's failure to do likewise. During the ten-day period commencing
     after receipt of such information is given, each Fully-Exercising Investor
     shall be entitled to obtain that portion of the Shares not subscribed for
     by the Investor which is equal to the proportion that the number of shares
     of Common Stock then held, by such Fully-Exercising Investor bears to the
     total number of shares of Common Stock issued and held, or issuable upon
     conversion of the Preferred Stock then held, by all Fully-Exercising
     Investors who wish to purchase some of the unsubscribed shares.


                                       14.

<PAGE>



          c. If all Shares referred to in the Notice are not elected to be
     obtained as provided in Subsection 4.4(b) hereof, the Company may, during
     the thirty-day period following the expiration of the period provided in
     subsection 4.4(b) hereof, offer the remaining unsubscribed portion of such
     Shares to any person or persons at a price not less than, and upon terms no
     more favorable to the offeree than those specified in the Notice. If the
     Company does not enter into an agreement for the sale of the Shares within
     such period, or if such agreement is not consummated within thirty (30)
     days of the execution thereof, the right provided hereunder shall be deemed
     to be revived and such Shares shall not be offered unless first reoffered
     to the Investors in accordance herewith.

          d. The right of first offer in this paragraph 4.4 shall not be
     applicable (i) to the issuance or sale of not to exceed 1,100,000 shares of
     Common Stock (or options therefor) to employees, directors and consultants
     for the primary purpose of soliciting or retaining their employment
     pursuant to a stock option or restricted stock purchase plan approved in
     accordance with Section 4.7 hereof, or (ii) to or after consummation of a
     bona fide, firmly underwritten public offering of shares of Common Stock,
     registered under the Act pursuant to a registration statement on Form S-1,
     at an offering price of at least $6.50 per share (appropriately adjusted
     for any stock split, dividend, combination or other recapitalization),
     (iii) the issuance of securities in connection with a bona fide business
     acquisition of or by the Company, whether by merger, consolidation, sale of
     assets, sale or exchange of stock or otherwise, (iv) issuances of the
     Series A, Series B and Series C Preferred Stock upon exercise of the
     Warrants (as defined in the Warrant Purchase Agreement), or (v) the
     issuance of stock, warrants or other securities or rights to persons or
     entitles with which the Company has business primarily equity financing
     purposes.

     4.5 Observer Rights. If the Investor does not have a representative on the
Board of Directors for any reason the Company shall invite a representative of
the Investor to attend all meetings of its Board of Directors in a nonvoting
observer capacity with participation rights and, in this respect, shall give
such representative copies of all notices, minutes, consents, and other
materials that it provides to its directors. Such Investor shall also have the
right to consult with and advise management of the Company on a monthly basis;
provided, however, that such representative shall agree to hold in confidence
and trust and to act in a fiduciary manner with respect to all information so
provided; and, provided further, that the Company reserves the right to withhold
any information and to exclude such representative from any meeting or portion
thereof if access to such information or attendance at such meeting could
adversely affect the attorney-client privilege between the Company and its
counsel.

     4.6 Termination of Certain Covenants. The covenants set forth in Section
4.5 shall terminate and be of no further force or effect upon the consummation
of the sale of securities pursuant to

                                       15.

<PAGE>



a registration statement filed by the Company under the Act in connection with
the firm commitment underwritten offering of its securities to the general
public.

     4.7 Employee Stock Purchase Agreements. The Company will not issue or grant
or agree to issue or grant any shares of its capital stock or any option, right
or warrant to purchase shares of its capital stock or securities convertible
into or exchangeable for shares of its capital stock to any employee or officer
of the Company or a subsidiary except pursuant to the a stock option plan or
restricted stock purchase plan adopted by the Board of Directors (a "Plan").
Such issuances or grants shall be made upon the Board's approval of management's
recommendations with respect to such issuances or grants. Each purchase of
shares of Common Stock or exercise of option to purchase such shares will be
conditioned upon the execution and delivery by the Company and such employee or
officer of an Employee Stock Purchase Agreement in substantially the form
attached as Exhibit D to the Proposed Agreement (with appropriate adjustments
with respect to vesting as determined by the Board of Directors).

     5. Miscellaneous.

     5.1 Governing Law. This Agreement shall be governed by and construed under
the laws of the State of California as applied to agreements among California
residents, made and to be performed entirely within the State of California.

     5.2 Successors and Assigns. Except as otherwise expressly provided herein,
the provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors, and administrators of the parties hereto.

     5.3 Entire Agreement. This Agreement constitutes the full and entire
understanding and agreement among the parties with regard to the subjects hereof
and no party shall be liable or bound to any other party in any manner by any
representations, warranties, covenants, or agreements except as specifically set
forth herein or therein. Nothing in this Agreement, express or implied, is
intended to confer upon any party, other than the parties hereto and their
respective successors and assigns, any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
herein.

     5.4 Separability. Any invalidity, illegality, or limitation of the
enforceability with respect to any party hereto of any one or more of the
provisions of this Agreement, or any part thereof, whether arising by reason of
the law of any such party's domicile or otherwise, shall in no way affect or
impair the validity, legality, or enforceability of this Agreement with respect
to other parties. In case any provision of this Agreement, shall be invalid,
illegal, or unenforceable, it shall to the extent practicable, be modified so as
to make it valid, legal and enforceable and to retain as nearly as practicable

the observance thereof may be waived (either generally or in a particular
instance and either retroactively or prospectively), only with the written
consent of the Company and the holders of at least two-thirds of the Registrable
Securities then outstanding. Any amendment or waiver regarding Section 3 of this

of this Agreement may be amended and the observance thereof may be waived

Preferred Stock held by the undersigned investors (not including any Common
Stock held by Martin Ellis, Jeffrey Kurland, Jerry Siegan or Marshall Ellis, or
transferees thereof). Any amendment or waiver regarding Section 4 of this
Agreement, effected in accordance with this paragraph, shall be binding upon
each Investor, each future transferee of Preferred Stock of the Company held by
an Investor, and the Company.

     5.6 Delays or Omissions. No delay or omission to exercise any right, power,
or remedy accruing to any party hereto or any subsequent holder of any
Registrable Securities upon any breach, default or noncompliance of the Company
under this Agreement, shall impair any such right, power, or remedy, nor shall
it be construed to be a waiver of any such breach, default or noncompliance, or
any acquiescence therein, or of any similar breach, default or noncompliance
thereafter occurring. It is further agreed that any waiver, permit, consent, or
approval of any kind or character on the part of the parties hereto of any
breach, default or noncompliance under this Agreement or any waiver on the part
of the parties hereto of any provisions or conditions of this Agreement must be
in writing and shall be effective only to the extent specifically set forth in
such writing, and that all remedies, either under this Agreement, by law, or
otherwise afforded to the parties hereto, shall be cumulative and not
alternative.

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY
MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, OR HYPOTHECATED IN THE ABSENCE OF AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL (WHICH
MAY BE COMPANY COUNSEL) REASONABLY SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.

                                WARRANT AGREEMENT

                  To Purchase Shares of the Preferred Stock of
                              Digitran Corporation
                         dated as of September 16, 1992

     WHEREAS, Digitran Corporation, a Delaware corporation (the "Company") has
entered into a Master Lease Agreement dated as of May 30, 1991, Equipment
Schedule #VL-2 dated as of September 16, 1992, and related Summary Equipment
Schedules (the "Leases") with Comdisco, Inc., a Delaware corporation (the
"Warrantholder"); and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Leases, the right to purchase shares of its Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Leases and in consideration of mutual covenants and agreements
contained herein, the Company and Warrantholder certify and agree as follows:

     1. GRANT OF TO PURCHASE PREFERRED STOCK. For value received, the Company
hereby grants to the Warrantholder, and the Warrantholder is entitled, upon the
terms and subject to the conditions hereinafter set forth, to subscribe for and
purchase, from the Company, 11,000 fully paid and non-assessable shares of the
Company's Preferred Series B Stock ("Preferred Stock") at a purchase price of
$1.00 per share (the "Exercise Price"). The number and purchase price of such
shares are subject to adjustment as provided in Section 8 hereof.

     2.(a). TERM OF THE WARRANT AGREEMENT. Except as otherwise provided for
herein, the term of this Warrant Agreement and the right to purchase Preferred
Stock as granted herein shall commence on the date of execution hereof and shall
be exercisable for a period of (i) ten (10) years after the date of execution
hereof, or(ii) or in accordance with paragraphs (b) or (c) below.

     (b) Notwithstanding the term of this Warrant Agreement fixed pursuant to
Section 2(a) above, the right to purchase Preferred Stock as granted herein
shall expire, if not previously exercised immediately upon the closing of either
of the following events:

     (i)  the issuance and sale of shares of Common Stock of the Company in the
          Company's first public offering of


<PAGE>



          securities for its own account pursuant to an effective registration
          statement under the Securities Act of 1933, as amended (the "Initial
          Public Offering"), provided, however, that (A) the Initial Public
          Offering price of the Common Stock (upon conversion of the Preferred
          Stock) exceeds $3.00 per share; and (B) the Warrantholder would be
          entitled to participate in the Company's IPO pro rata with the other
          stockholders of the Company.

     (ii) a merger or consolidation of the Company with or into another
          corporation when the Company is not the surviving corporation, or the
          sale of all or substantially all of the Company's properties and
          assets to any other person (the "Merger") provided in which
          Warrantholder realizes a value for its shares equal to or greater than
          $2.00 per share.

     The Company shall notify the Warrantholder if the Initial Public Offering
or Merger is proposed in accordance with the terms of Subsection 8(g) hereof,
and if the Company fails to deliver such written notice, then notwithstanding
anything to the contrary in this Warrant Agreement, the rights to purchase the
Company's Preferred Stock shall not expire until the Company complies with such
notice provisions. Such notice shall also contain such details of the proposed
Initial Public Offering or Merger as are reasonable in the circumstances. If
such closing does not take place, the Company shall promptly notify the
Warrantholder that such proposed transaction has been terminated, and the
Warrantholder may rescind any exercise of its purchase rights promptly after
such notice of termination of the proposed transaction if the exercise of
Warrants occurred after the Company notified the Warrantholder that the Initial
Public Offering or Merger was proposed or if the exercise were otherwise
precipitated by such proposed Initial Public Offering or Merger. In the event of
such rescission, the Warrants will continue to be exercisable on the same terms
and conditions contained herein.

     3. EXERCISE OF THE PURCHASE RIGHTS. The purchase rights set forth in this
Warrant Agreement are exercisable by the Warrantholder, in whole or in part, at
any time, or from time to time, prior to the expiration of the term set forth in
Section 2 above, by tendering to the Company at its principal office a notice of
exercise in the form attached hereto as Exhibit I (the "Notice of Exercise"),
duly completed and executed. Upon receipt of the Notice of Exercise and the
payment of the purchase price in accordance with the terms set forth below, the
Company shall issue to the Warrantholder a certificate for the number of shares
of Preferred Stock purchased and shall execute the Notice of Exercise indicating
the number of shares which remain subject to future purchases, if any.

     Notwithstanding anything to the contrary contained in Section 2 above or
this Section 3, the Warrantholder shall either (i) exercise all outstanding
warrants by paying to the Company, by cash or check, an amount equal to the
aggregate Warrant Price of the

                                       -2-

<PAGE>



shares being purchased, or (ii) receive shares equal to the value (as determined
below) of this Warrant by surrender of the Warrant at the principal office of
the Company together with notice of such election in which event the Company
shall issue to the Warrantholder a number of shares of Preferred computed using
the following formula:

         X = Y(A-B)
            -------
                A

Where:   X = the number of shares of Preferred to be issued to
             the Warrantholder.

         Y = the number of shares of Preferred under this Warrant.

         A = the fair market value of one share of Common.

         B = Exercise Price.

     As used herein, current fair market value of Common Stock shall mean with
respect to each share of Common Stock the average of the closing prices of the
Company's Common Stock sold on all securities exchanges on which the Common
Stock may at the time be listed, or, if there have been no sales on any such
exchange on any day, the average of the highest bid and lowest asked prices on
all such exchanges at the end of such day, or, if on any day the Common Stock is
not so listed, the average of the representative bid and asked prices quoted in
the NASDAQ System as of 4:00 p.m., New York City time, or, if on any day the
Common Stock is not quoted in the NASDAQ System, the average of the highest bid
and lowest asked price on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of 21 days
consisting of the day as of which the current fair market value of Common Stock
is being determined and the 20 consecutive business days prior to such day. If
at any time the Common Stock is not listed on any securities exchange or quoted
in the NASDAQ System or the over-the-counter market, the current fair market
value of Preferred Stock shall be the highest price per share which the Company
could obtain from a willing buyer (not a current employee or director) for
shares of Preferred Stock sold by the Company, from authorized but unissued
shares, as determined in good faith by the Board of Directors of the Company,
unless (i) the Company shall become subject to a merger, acquisition or other
consolidation pursuant to which the Company is not the surviving party, in which
case the current fair market value of the Preferred Stock shall be deemed to be
the value received by the holders of the Company's Series B Preferred Stock for
each share of Series B Preferred Stock (or Common Stock if all such shares have
been converted into Common Stock) pursuant to the Company's Acquisition; or (ii)
the Warrantholder shall purchase such shares in conjunction with the initial
underwritten public offering of the Company's Common Stock pursuant to a
registration statement filed under the Securities Act of 1933, in which case,
the fair market value of the

                                       -3-

<PAGE>



shares of stock subject to this Warrant shall be the price at which all
registered shares are sold to the public in such offering.


     4.  RESERVATION OF SHARES.

     (a) Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b) Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of exercise of the Warrant Agreement hereunder require
registration with or approval of any governmental authority under any Federal or
State law (other than any registration under the Securities Act of 1933, as then
in effect, or any similar Federal statute then enforced, or any state securities
law, required by reason of any transfer involved in such conversion), or listing
on any domestic securities exchange, before such shares may be issued upon
conversion, the Company will, at its expense and as expeditiously as possible,
use its best efforts to cause such shares to be duly registered, listed or
approved for listing on such domestic securities exchange, as the case may be.

     5. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of the
Warrantholder's rights to purchase Preferred Stock, but in lieu of such
fractional shares the Company shall make a cash payment therefor upon the basis
of the Exercise Price then in effect.

     6. NO RIGHTS AS SHAREHOLDERS. This Warrant Agreement does not entitle the
Warrantholder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrantholder's rights to purchase
Preferred Stock as provided for herein.

     7. WARRANTHOLDER REGISTRY. The Company shall maintain a registry showing
the name and address of the registered holder of this Warrant Agreement.

     8. ADJUSTMENT RIGHTS. The purchase price per share and the number of shares
of Preferred Stock purchasable hereunder are subject to adjustment from time to
time, as follows:

     (a) Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation when the Company is not the surviving corporation, or the sale of
all or substantially all of the Company's properties and assets to any other
person, then, as a part of such reorganization, merger, consolidation or sale,
lawful provision shall be made so that the

                                       -4-

<PAGE>



Warrantholder shall thereafter be entitled to receive upon exercise of its
rights to purchase Preferred Stock, the number of shares of Preferred Stock or
other securities of the successor corporation resulting from such merger or
consolidation, to which a holder of the Preferred Stock deliverable upon
exercise of the right to purchase Preferred Stock hereunder would have been
entitled in such capital reorganization, merger, consolidation or sale if the
right to purchase such Preferred Stock hereunder had been exercised immediately
prior to such capital reorganization, merger, consolidation or sale. In any such
case, appropriate adjustment (as determined in good faith by the Company's Board
of Directors) shall be made in the application of the provisions of this Warrant
Agreement with respect to the rights and interest of the Warrantholder after the
reorganization, merger, consolidation or sale to the end that the provisions of
this Warrant Agreement (including adjustments of the Exercise Price and number
of shares of Preferred Stock purchasable pursuant to the terms and conditions of
this Warrant Agreement) shall be applicable after that event, as near as
reasonably may be, in relation to any shares deliverable after that event upon
the exercise of the Warrantholder's rights to purchase Preferred Stock pursuant
to this Warrant Agreement.

     (b) Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares. If the Company at any time shall
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d) Stock Dividends. If the Company at any time shall pay a dividend
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the date of
determination of stockholders entitled to receive such dividend or distribution,
to that price determined by multiplying the Exercise Price in effect immediately
prior to such date of determination by a fraction (i) the numerator of which
shall be the total number of all shares of the Company's stock outstanding
immediately prior to such dividend or distribution, and (ii) the denominator of
which shall be the total number of all shares of the Company's stock outstanding
immediately after such dividend or distribution. The Warrantholder shall
thereafter be entitled to purchase, at the Exercise Price resulting from such
adjustment, the number of shares of Preferred

                                       -5-

<PAGE>



Stock (calculated to the nearest whole share) obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares of Preferred Stock issuable upon the exercise hereof immediately prior to
such adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment.

     (e) Issuance of Shares at Other Than Exercise Price. If the Company should
issue shares of its stock or any other equity security at a price per share less
than the Exercise Price in effect immediately prior to such issuance, then the
Exercise Price shall be adjusted by dividing (i) the sum of (A) the total number
of shares of the Company's stock outstanding immediately prior to such issuance
multiplied by the then effective Exercise Price and (B) the value of the
consideration received by the Company upon such issuance of such shares, by (ii)
the total number of shares of the Company's stock outstanding immediately after
such issuance. The Warrantholder shall thereafter be entitled to purchase, at
the Exercise Price resulting from such adjustment, the number of shares of
Preferred Stock (calculated to the nearest whole share) obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of shares of Preferred Stock issuable upon the exercise hereof immediately prior
to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment. For the purposes of this paragraph (e), the
issuance of securities convertible into or exercisable for the Preferred Stock
shall be deemed the issuance of the number of shares of Preferred Stock into
which such securities are convertible or for which such securities are
exercisable, and the consideration received for such securities shall be deemed
to include the minimum aggregate amount payable upon conversion or exercise of
such securities. In the event the right to convert or exercise such securities
expires unexercised, the Exercise Price of shares issuable upon the exercise
hereof shall be readjusted accordingly.

     (f) Right to Purchase Additional Stock. If, for any reason, the total
Warrantholder's cost of equipment leased pursuant to the Leases should exceed
$100,000, Warrantholder shall have the right to purchase from the Company, at
the Exercise Price per share specified in section 1 (which price may be subject
to adjustment from time to time as provided for in this Section 8), an
additional number of shares, which number shall be determined by (i) multiplying
the amount by which the Warrantholder's total equipment cost exceeds $100,000 by
11%, and (ii) dividing the product thereof by the Exercise Price per share
referenced above.

     (g) Notice of Adjustments. In the event that: (i) the Company shall declare
any dividend or distribution upon its stock, whether in cash, property, stock or
other securities; (ii) the Company shall offer for subscription pro rata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any capital
reorganization, reclassification, consolidation, merger or sale of all or
substantially all of the Company's assets; or

                                       -6-

<PAGE>



(iv) there shall be any voluntary or involuntary dissolution, liquidation or
winding up of the Company; then, in connection with each such event, the Company
shall send to the Warrantholder:

         (i) At least 20 days' prior written notice of the date on which the
     books of the Company shall close or a record shall be taken for such
     dividend, distribution, subscription rights (specifying the date on which
     the holders of Preferred Stock shall be entitled thereto) or for
     determining rights to vote in respect of such capital reorganization,
     reclassification, consolidation, merger or sale of all or substantially all
     of the Company's assets, dissolution, liquidation or winding up; and

         (ii) In the case of any such capital reorganization, reclassification,
     consolidation, merger or sale of all or substantially all of the Company's
     assets, dissolution, liquidation or winding up, at least 20 days' prior
     written notice of the date when the same shall take place (and specifying
     the date on which the holders of Preferred Stock shall be entitled to
     exchange their Preferred Stock for securities or other property deliverable
     upon such capital reorganization, reclassification, consolidation, merger
     or sale of all or substantially all of the Company's assets, dissolution,
     liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (h) Registration and Listing. The Company will take all such actions as may
be necessary to assure that all shares of Preferred Stock issuable pursuant to
this Warrant Agreement may be so issued without violation of any applicable law
or regulation or any requirements of any domestic stock exchange (except for
official notice of issuance, which will be immediately transmitted by the
Company upon issuance) upon which shares of Preferred Stock or other shares of
the same class may be listed. The Company will not take any action which will
result in any adjustment of the number of shares of Preferred Stock issuable
upon exercise of this Warrant Agreement if the total number of shares of
Preferred Stock issuable after such action upon exercise of the Warrant
Agreement then outstanding, together with the total number of shares of
Preferred Stock then outstanding, would exceed the total number of shares of
Preferred Stock then authorized and not reserved for any purpose other than the
purpose of issue upon exercise of the Warrant Agreement.



                                       -7-

     9. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a) Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will be
validly issued, fully paid and non-assessable, and will be free of any taxes,
liens, charges or encumbrances of any nature whatsoever; provided, however, that
the Preferred Stock issuable pursuant to this Warrant Agreement may be subject
to restrictions on transfer under state and/or Federal securities laws. The
Company has made available to the Warrantholder true, correct and complete
copies of its Articles of Incorporation and By-Laws, as amended, and minutes of
all Board of Directors (including all committees of the Board of Directors, if
any) and Shareholder meetings the Company's inception through May 16, 1991. The
issuance of certificates for shares of Preferred Stock upon exercise of the
Warrant Agreement shall be made without charge to the Warrantholder for any
issuance tax in respect thereof, or other cost incurred by the company in
connection with such exercise and the related issuance of shares of Preferred
Stock; provided that the Company shall not be required to pay any tax which may
be payable in respect of any transfer involved and the issuance and delivery of
any certificate in a name other than that of the Warrantholder. The Company will
not close its books against the transfer of the Warrant Agreement or of any
share of Preferred Stock issued or issuable upon exercise of the Warrant and any
agreement in any manner which interferes with the timely exercise of the
Warrant.

     (b) Due Authority. The execution and delivery by the Company of the Leases,
and this Warrant Agreement and the performance of all obligations of the Company
thereunder and hereunder, including the issuance to Warrantholder of the right
to acquire the shares of Preferred Stock set forth in Section 1 above (which

     (r) Indebtedness to Employees and Shareholders. The Company is not indebted

     10. REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER. This Warrant
Agreement has been entered into by the Company in reliance upon the following
representations and covenants of the Warrantholder, which by its execution
hereof the Warrantholder hereby confirms:

     (a) Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b) Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of the Warrantholder's rights contained herein is
not registered under the 1933 Act or qualified under applicable state securities
laws on the ground that the issuance contemplated by this Warrant Agreement will
be exempt from the registration and qualifications requirements thereof, and
(ii) that the Company's reliance on such exemption is predicated on the
representations set forth in this Section 10.

     (c) Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available. Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred

                                      -12-

<PAGE>



without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. Whenever the restrictions
imposed hereunder shall terminate, as hereinabove provided, the Warrantholder or
holder of a share of Preferred Stock then outstanding as to which such
restrictions have terminated shall be entitled to receive from the Company,
without expense to such holder, one or more new certificates for the Warrant or
for such shares of Preferred Stock not bearing any restrictive legend.

     (d) Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment and has the ability to bear the economic risks of its
investment.

     (e) Risk of No Registration. The Warrantholder understands that if the
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1933 Act, or file reports pursuant to Section 15(d), of the
Securities Exchange Act of 1934 (the "1934 Act"), or if a registration statement
covering the securities under the 1933 Act is not in effect when it desires to
sell (i) the rights to purchase Preferred Stock pursuant to this Warrant
Agreement, or (ii) the Preferred Stock issuable upon exercise of the right to
purchase, it may be required to hold such securities for an indefinite period.
The Warrantholder also understands that any sale of its rights of the
Warrantholder to purchase Preferred Stock or Preferred Stock which might be made
by it in reliance upon Rule 144 under the 1933 Act may be made only in
accordance with the terms and conditions of that Rule.

     11. Registration Rights. Warrantholder and Company agree that all shares of
Preferred Stock subject to the Warrant Agreement shall have the same
registration rights and be subject to the same terms and conditions with respect
to the registration and sale of such stock as possessed by the Series B
Preferred Shareholders as provided for in the Second Investors Rights Agreement
dated April 15, 1991, by and among the Company and those certain Purchasers
identified therein, attached hereto as Exhibit II.

     12. TRANSFERS. Subject to the terms and conditions contained in Section 10
hereof, this Warrant Agreement and all rights hereunder are transferable in
whole or in part by the Warrantholder and any successor transferee, provided,
however, that in no event shall the number of transfers of the rights and
interests in all of the Warrants exceed three (3) transfers. The transfer shall
be recorded on the books of the Company upon receipt by the Company of a notice
of transfer in the form attached hereto as Exhibit III (the "Transfer Notice"),
at its principal offices and the payment to the Company of all transfer taxes
and other governmental charges imposed on such transfer.

                                WARRANT AGREEMENT

                  To Purchase Shares of the Preferred Stock of
                              Digitran Corporation
                          dated as of October 28, 1993

     WHEREAS, Digitran Corporation, a Delaware corporation (the "Company") has
entered into a Forbearance Agreement dated as of October 28, 1993 (the
"Agreement") with Comdisco, Inc., a Delaware corporation (the "Warrantholder");
and

     WHEREAS, the Company desires to grant to Warrantholder, in consideration
for such Agreement, the right to purchase shares of its Preferred Stock;

     NOW, THEREFORE, in consideration of the Warrantholder executing and
delivering such Agreement and in consideration of mutual covenants and
agreements contained herein, the Company and Warrantholder certify and agree as
follows:

     1. GRANT OF THE RIGHT TO PURCHASE SERIES D PREFERRED STOCK. For value
received, the Company hereby grants to the Warrantholder, and the Warrantholder
is entitled, upon the terms and subject to the conditions hereinafter set forth,
to subscribe for and purchase, from the Company, 87,570 fully paid and
non-assessable shares of the Company's Series D Preferred Stock ("Preferred
Stock") at a purchase price of $.1733 per share (the "Exercise Price") . The
number and purchase price of such shares are subject to adjustment as provided
in Section 8 hereof.

     2. (a) TERM OF THE WARRANT AGREEMENT. Except as otherwise provided for
herein, the term of this Warrant Agreement and the right to purchase Preferred
Stock as granted herein shall commence on the date of execution hereof and shall
be exercisable for a period of (i) ten (10) years after the date of execution
hereof, or (ii) in accordance with paragraphs (b) or (c) below.

     (b) Notwithstanding the term of this Warrant Agreement fixed pursuant to
Section 2(a) above, the right to purchase Preferred Stock as granted herein
shall expire, if not previously exercised immediately upon the closing of either
of the following events:

     (i)  the issuance and sale of shares of Common Stock of the Company in the
          Company's first

<PAGE>


          public offering of securities for its own account pursuant to an
          effective registration statement under the Securities Act of 1933, as
          amended (the "Initial Public Offering"), provided, however, that (A)
          the Initial Public Offering price of the Common Stock (upon conversion
          of the Preferred Stock) exceeds $3.00 per share; and (B) the
          Warrantholder would be entitled to participate in the Company's IPO
          pro rata with the other stockholders of the Company.

     (ii) a merger or consolidation of the Company with or into another
          corporation when the Company is not the surviving corporation, or the
          sale of all or substantially all of the Company's properties and
          assets to any other person (the "Merger") provided in which
          Warrantholder realizes a value for its shares equal to or greater than
          $2.00 per share.

     The Company shall notify the Warrantholder if the Initial Public Offering
or Merger is proposed in accordance with the terms of Subsection 8(g) hereof,
and if the Company fails to deliver such written notice, then notwithstanding
anything to the contrary in this Warrant Agreement, the rights to purchase the
Company's Preferred Stock shall not expire until the Company complies with such
notice provisions. Such notice shall also contain such details of the proposed
Initial Public Offering or Merger as are reasonable in the circumstances. If
such closing does not take place, the Company shall promptly notify the
Warrantholder that such proposed transaction has been terminated, and the
Warrantholder may rescind any exercise of its purchase rights promptly after
such notice of termination of the proposed transaction if the exercise of
Warrants occurred after the Company notified the Warrantholder that the Initial
Public Offering or Merger was proposed or if the exercise were otherwise
precipitated by such proposed Initial Public Offering or Merger. In the event of
such rescission, the Warrants will continue to be exercisable on the same terms
and conditions contained herein.

     3. EXERCISE OF THE PURCHASE RIGHTS. The purchase rights set forth in this
Warrant Agreement are exercisable by the Warrantholder, in whole or in part, at
any time, or from time to time, prior to the expiration of the term set forth in
Section 2 above, by tendering to the Company at its principal office a notice of
exercise in the form attached hereto as Exhibit I (the "Notice of Exercise"),
duly completed and executed. Upon receipt of the Notice of Exercise and the
payment of the purchase price in accordance with the terms set forth below, the
Company shall issue to the Warrantholder a certificate for the number of shares
of Preferred Stock purchased and shall execute the Notice of Exercise indicating
the number of shares which remain subject to future purchases, if any.

     Notwithstanding anything to the contrary contained in Section 2 above or
this Section 3, the Warrantholder shall either (i) exercise all outstanding
warrants by paying to the Company, by cash or check, an amount equal to the
aggregate Warrant Price of the shares being purchased, or (ii) receive shares
equal to the value (as determined below) of this Warrant by surrender of the
Warrant at the principal office of the Company together with notice of such
election in which event the Company shall issue to the Warrantholder a number of
shares of Preferred computed using the following formula:

         X = Y(A-B)
             ------
              A

Where:   X = the number of shares of Preferred to be issued to
             the Warrantholder.

         Y = the number of shares of Preferred under this Warrant.

         A = the fair market value of one share of Common.

         B = Exercise Price.

     As used herein, current fair market value of Common Stock shall mean with
respect to each share of Common Stock the average of the closing prices of the
Company's Common Stock sold on all securities exchanges on which the Common
Stock may at the time be listed, or, if there have been no sales on any such
exchange on any day, the average of the highest bid and lowest asked prices on
all such exchanges at the end of such day, or, if on any day the Common Stock is
not so listed, the average of the representative bid and asked prices quoted in
the NASDAQ System as of 4:00 p.m., New York City time, or, if on any day the
Common Stock is not quoted in the NASDAQ System, the average of the highest bid
and lowest asked price on such day in the domestic over-the-counter market as
reported by the National Quotation Bureau, Incorporated, or any similar
successor organization, in each such case averaged over a period of 21 days
consisting of the day as of which the current fair market value of Common Stock
is being determined and the 20 consecutive business days prior to such day. If
at any time the Common Stock is not listed on any securities exchange or quoted
in the NASDAQ System or the over-the-counter market, the current fair market
value of Preferred Stock shall be the highest price per share which the Company
could obtain from a willing buyer (not a current employee or director) for
shares of Preferred Stock sold by the Company, from authorized but unissued
shares, as determined in good faith by the Board of Directors of the Company,
unless (i) the Company shall become subject to a merger, acquisition or other
consolidation pursuant to which the Company is not the surviving party, in which
case the current fair market value of the Preferred Stock shall be deemed to be
the value received by the holders of the Company's Series A Preferred Stock for
each share of Series A Preferred Stock (or Common Stock if all such shares have
been

                                      - 3 -

<PAGE>



converted into Common Stock) pursuant to the Company's Acquisition; or (ii) the
Warrantholder shall purchase such shares in conjunction with the initial
underwritten public offering of the Company's Common Stock pursuant to a
registration statement filed under the Securities Act of 1933, in which case,
the fair market value of the shares of stock subject to this Warrant shall be
the price at which all registered shares are sold to the public in such
offering.

     4.  RESERVATION OF SHARES.

     (a) Authorization and Reservation of Shares. During the term of this
Warrant Agreement, the Company will at all times have authorized and reserved a
sufficient number of shares of its Preferred Stock to provide for the exercise
of the rights to purchase Preferred Stock as provided for herein.

     (b) Registration or Listing. If any shares of Preferred Stock required to
be reserved for purposes of exercise of the Warrant Agreement hereunder require
registration with or approval of any governmental authority under any Federal or
State law (other than any registration under the Securities Act of 1933, as then
in effect, or any similar Federal statute then enforced, or any state securities
law, required by reason of any transfer involved in such conversion), or listing
on any domestic securities exchange, before such shares may be issued upon
conversion, the Company will, at its expense and as expeditiously as possible,
use its best efforts to cause such shares to be duly registered, listed or
approved for listing on such domestic securities exchange, as the case may be.

     5. NO FRACTIONAL SHARES OR SCRIP. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of the
Warrantholder's rights to purchase Preferred Stock, but in lieu of such
fractional shares the Company shall make a cash payment therefor upon the basis
of the Exercise Price then in effect.

     6. NO RIGHTS AS SHAREHOLDERS. This Warrant Agreement does not entitle the
Warrantholder to any voting rights or other rights as a shareholder of the
Company prior to the exercise of the Warrantholder's rights to purchase
Preferred Stock as provided for herein.

     7. WARRANTHOLDER REGISTRY. The Company shall maintain a registry showing
the name and address of the registered holder of this Warrant Agreement.

     8. ADJUSTMENT RIGHTS. The purchase price per share and the number of shares
of Preferred Stock purchasable hereunder are subject to adjustment from time to
time, as follows:

     (a) Merger and Sale of Assets. If at any time there shall be a capital
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger

                                      - 4 -

<PAGE>



or consolidation of the Company with or into another corporation when the
Company is not the surviving corporation, or the sale of all or substantially
all of the Company's properties and assets to any other person, then, as a part
of such reorganization, merger, consolidation or sale, lawful provision shall be
made so that the Warrantholder shall thereafter be entitled to receive upon
exercise of its rights to purchase Preferred Stock, the number of shares of
Preferred Stock or other securities of the successor corporation resulting from
such merger or consolidation, to which a holder of the Preferred Stock
deliverable upon exercise of the right to purchase Preferred Stock hereunder
would have been entitled in such capital reorganization, merger, consolidation
or sale if the right to purchase such Preferred Stock hereunder had been
exercised immediately prior to such capital reorganization, merger,
consolidation or sale. In any such case, appropriate adjustment (as determined
in good faith by the Company's Board of Directors) shall be made in the
application of the provisions of this Warrant Agreement with respect to the
rights and interest of the Warrantholder after the reorganization, merger,
consolidation or sale to the end that the provisions of this Warrant Agreement
(including adjustments of the Exercise Price and number of shares of Preferred
Stock purchasable pursuant to the terms and conditions of this Warrant
Agreement) shall be applicable after that event, as near as reasonably may be,
in relation to any shares deliverable after that event upon the exercise of the
Warrantholder's rights to purchase Preferred Stock pursuant to this Warrant
Agreement.

     (b) Reclassification of Shares. If the Company at any time shall, by
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares. If the Company at any time shall
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d) Stock Dividends. If the Company at any time shall pay a dividend
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the date of
determination of stockholders entitled to receive such dividend or distribution,
to that price determined by multiplying the Exercise Price in effect immediately
prior to such date of determination by a fraction (i) the numerator of which
shall be the total number of all shares

                                      - 5 -

<PAGE>



of the Company's stock outstanding immediately prior to such dividend or
distribution, and (ii) the denominator of which shall be the total number of all
shares of the Company's stock outstanding immediately after such dividend or
distribution. The Warrantholder shall thereafter be entitled to purchase, at the
Exercise Price resulting from such adjustment, the number of shares of Preferred
Stock (calculated to the nearest whole share) obtained by multiplying the
Exercise Price in effect immediately prior to such adjustment by the number of
shares of Preferred Stock issuable upon the exercise hereof immediately prior to
such adjustment and dividing the product thereof by the Exercise Price resulting
from such adjustment.

     (e) Issuance of Shares at Other Than Exercise Price. If the Company should
issue shares of its stock or any other equity security at a price per share less
than the Exercise Price in effect immediately prior to such issuance, then the
Exercise Price shall be adjusted by dividing (i) the sum of (A) the total number
of shares of the Company's stock outstanding immediately prior to such issuance
multiplied by the then effective Exercise Price and (B) the value of the
consideration received by the Company upon such issuance of such shares, by (ii)
the total number of shares of the Company's stock outstanding immediately after
such issuance. The Warrantholder shall thereafter be entitled to purchase, at
the Exercise Price resulting from such adjustment, the number of shares of
Preferred Stock (calculated to the nearest whole share) obtained by multiplying
the Exercise Price in effect immediately prior to such adjustment by the number
of shares of Preferred Stock issuable upon the exercise hereof immediately prior
to such adjustment and dividing the product thereof by the Exercise Price
resulting from such adjustment. For the purposes of this paragraph (e), the
issuance of securities convertible into or exercisable for the Preferred Stock
shall be deemed the issuance of the number of shares of Preferred Stock into
which such securities are convertible or for which such securities are
exercisable, and the consideration received for such securities shall be deemed
to include the minimum aggregate amount payable upon conversion or exercise of
such securities. In the event the right to convert or exercise such securities
expires unexercised, the Exercise Price of shares issuable upon the exercise
hereof shall be readjusted accordingly.

     (f) Right to Purchase Additional Stock. If, for any reason, the total
amount of Warrantholder's forbearance pursuant to the Forbearance Agreement
should exceed $87,570, Warrantholder shall have the right to purchase from the
Company, at the Exercise Price per share specified in Section 1 (which price may
be subject to adjustment from time to time as provided for in this Section 8),
an additional number of shares, which number shall be determined by (i)
multiplying the amount by which the Warrantholder's total equipment cost exceeds
$89,473 by 100%, and (ii) dividing the product thereof by the Exercise Price per
share referenced above.


                                      - 6 -

<PAGE>



     (g) Notice of Adjustments. In the event that: (i) the Company shall declare
any dividend or distribution upon its stock, whether in cash, property, stock or
other securities; (ii) the Company shall offer for subscription prorata to the
holders of any class of its Preferred or other convertible stock any additional
shares of stock of any class or other rights; (iii) there shall be any capital
reorganization, reclassification, consolidation, merger or sale of all or
substantially all of the Company's assets; or (iv) there shall be any voluntary
or involuntary dissolution, liquidation or winding up of the Company; then, in
connection with each such event, the Company shall send to the Warrantholder:

         (i) At least 20 days' prior written notice of the date on which the
     books of the Company shall close or a record shall be taken for such
     dividend, distribution, subscription rights (specifying the date on which
     the holders of Preferred Stock shall be entitled thereto) or for
     determining rights to vote in respect of such capital reorganization,
     reclassification, consolidation, merger or sale of all or substantially all
     of the Company's assets, dissolution, liquidation or winding up; and

         (ii) In the case of any such capital reorganization, reclassification,
     consolidation, merger or sale of all or substantially all of the Company's
     assets, dissolution, liquidation or winding up, at least 20 days' prior
     written notice of the date when the same shall take place (and specifying
     the date on which the holders of Preferred Stock shall be entitled to
     exchange their Preferred Stock for securities or other property deliverable
     upon such capital reorganization, reclassification, consolidation, merger
     or sale of all or substantially all of the Company's assets, dissolution,
     liquidation or winding up).

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (iv) the Exercise Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (h) Registration and Listing. The Company will take all such actions as may
be necessary to assure that all shares of Preferred Stock issuable pursuant to
this Warrant Agreement may be so issued without violation of any applicable law
or regulation or any requirements of any domestic stock exchange (except for
official notice of issuance, which will be immediately transmitted by the
Company upon issuance) upon which shares of Preferred Stock or other shares of
the same class may be listed. The Company will not take any action which will
result in any adjustment of the number of shares of Preferred Stock issuable
upon exercise of this Warrant Agreement if the total number of shares of
Preferred Stock issuable

                                      - 7 -

<PAGE>



after such action upon exercise of the Warrant Agreement then outstanding,
together with the total number of shares of Preferred Stock then outstanding,
would exceed the total number of shares of Preferred Stock then authorized and
not reserved for any purpose other than the purpose of issue upon exercise of
the Warrant Agreement.

     9.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE COMPANY.

     (a) Reservation of Preferred Stock. The Preferred Stock issuable upon
exercise of the Warrantholder's rights has been duly and validly reserved and,
when issued in accordance with the provisions of this Warrant Agreement, will be
validly issued, fully paid and non-assessable, and will be free of any taxes,
liens, charges or encumbrances of any nature whatsoever; provided, however, that
the Preferred Stock issuable pursuant to this Warrant Agreement may be subject
to restrictions on transfer under state and/or Federal securities laws. The
Company has made available to the Warrantholder true, correct and complete
copies of its Articles of Incorporation and By-Laws, as amended, and minutes of
all Board of Directors (including all committees of the Board of Directors, if
any) and Shareholder meetings from the Company's inception through May 16, 1991.
The issuance of certificates for shares of Preferred Stock upon exercise of the
Warrant Agreement shall be made without charge to the Warrantholder for any
issuance tax in respect thereof, or other cost incurred by the Company in
connection with such exercise and the related issuance of shares of Preferred
Stock; provided that the Company shall not be required to pay any tax which may
be payable in respect of any transfer involved and the issuance and delivery of
any certificate in a name other than that of the Warrantholder. The Company will
not close its books against the transfer of the Warrant Agreement or of any
share of Preferred Stock issued or issuable upon exercise of the Warrant and any
agreement in any manner which interferes with the timely exercise of the
Warrant.

     (b) Due Authority. The execution and delivery by the Company of the
Agreement, and this Warrant Agreement and the performance of all obligations of
the Company thereunder and hereunder, including the issuance to Warrantholder of
the right to acquire the shares of Preferred Stock set forth in Section 1 above
(which number of shares may be from time to time adjusted pursuant to the terms
of Section 8 above) have been duly authorized by all necessary corporate action
on the part of the Company, and the Agreement and this Warrant Agreement are not
inconsistent with the Company's Certificate of Incorporation or By-Laws, do not
contravene any law or governmental rule, regulation or order applicable to it,
do not and will not contravene any provision of, or constitute a default under,
any indenture, mortgage, contract or other instrument to which it is a party or
by which it is bound, and the Agreement and this Warrant Agreement constitute
legal, valid and binding agreements of the Company, enforceable in accordance
with their respective terms.

     10. REPRESENTATIONS AND COVENANTS OF THE WARRANTHOLDER. This Warrant
Agreement has been entered into by the Company in reliance upon the following
representations and covenants of the Warrantholder, which by its execution
hereof the Warrantholder hereby confirms:

     (a) Investment Purpose. The right to acquire Preferred Stock or the
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b) Private Issue. The Warrantholder understands (i) that the Preferred
Stock issuable upon exercise of the Warrantholder's rights contained herein is
not registered under the 1933 Act or qualified under applicable state securities
laws on the ground that the issuance contemplated by this Warrant Agreement will
be exempt from the registration and qualifications requirements thereof, and
(ii) that the Company's reliance on such exemption is predicated on the
representations set forth in this Section 10.

     (c) Disposition of Warrantholder's Rights. In no event will the
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until (i) it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available.

                                     - 12 -

<PAGE>



Notwithstanding the foregoing, the restrictions imposed upon the transferability
of any of its rights to acquire Preferred Stock or Preferred Stock issuable on
the exercise of such rights do not apply to transfers from the beneficial owner
of any of the aforementioned securities to its nominee or from such nominee to
its beneficial owner, and shall terminate as to any particular share of
Preferred Stock when (1) such security shall have been effectively registered
under the 1933 Act and sold by the holder thereof in accordance with such
registration or (2) such security shall have been sold without registration in
compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required. Whenever the
restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d) Financial Risk. The Warrantholder has such knowledge and experience in
financial and business matters as to be capable of evaluating the merits and
risks of its investment and has the ability to bear the economic risks of its
investment.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1993, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT

CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.


                            WARRANT TO PURCHASE STOCK

Issue Date: February 15, 1993
Expiration Date: Seven years from issuance
Exercise Price: See Preamble Below
Number and Class of Stock: See Preamble Below

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, LTI Ventures Leasing Corp., ("Holder") is
entitled to purchase 50,000 fully paid and nonassessable shares of the common
stock, $.0025 par value per share (the "Shares"), of Digitran Corporation (the
"Company") as may be purchased for Thirty Thousand Dollars ($30,000) (the "Face
Value") at an initial exercise price per share (the "Warrant Price") equal to
sixty cents ($.60); as adjusted pursuant to Article 2 of this Warrant, subject
to the provisions and upon the terms and conditions set forth of this Warrant.

ARTICLE 1.  EXERCISE AND EARLY TERMINATION

     1.1 Method of Exercise. Holder may exercise this Warrant by delivering a
duly executed Notice of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the shares being purchased.

     1.2 Conversion Right. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this warrant, in whole or in
part, into a number of shares determined by dividing (a) the aggregate fair
market value of the shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

     1.3 Fair Market Value. If the Shares are traded in a public market, the
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not traded in a public
market, the Board of Directors of the Company shall determine fair market value
in its reasonable good faith judgment. The foregoing notwithstanding, if Holder
advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment


<PAGE>



banking firm is greater than that of such investment banking firm shall be paid
by the Company. In all other circumstances, such fees and expenses shall be paid
by Holder.

     1.4 Delivery of Certificate and New Warrant. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, or surrender and cancellation of this Warrant, the Company
at its expense shall execute dna deliver, in lieu of this Warrant, a new warrant
of like tenor.

     1.6  Repurchase on Sale, Merger, or Consolidation of the Company.

         1.6.1 "Acquisition". For the purpose of this Warrant, "Acquisition"
means any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

         1.6.2 Assumption of Warrant. If upon the closing of any Acquisition the
successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

         1.6.3 Nonassumption. If upon the closing of any Acquisition and
successor entity does not assume the obligations of this Warrant and Holder has
not otherwise exercised this Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the acquisition on the
same terms as other holders of the same class of securities of the Company.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES

     2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, subdivides the
outstanding common stock into a greater amount of common stock, or, if the
Shares are securities other than common stock, subdivides the Shares in a
transaction that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive, without cost of Holder, the total number and kind of securities
to which Holder would have been

                                      - 2 -

<PAGE>



entitled had Holder owned the Shares of record as of the date the dividend or
subdivision occurred.

     2.2 Reclassification, Exchange or Substitution. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Certificate of Incorporation upon
the closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events.

     2.3 Adjustments for Combinations, Etc. If the outstanding Shares are
Combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4 Adjustments for Diluting Issuances. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant or, if the Shares are Preferred
Stock, the number of shares of common stock issuable upon conversion of the
Shares, shall be subject to adjustment, from time to time in the manner set
forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit A).

     2.5 No Impairment. The Company shall not, by amendment of its Certificate
of Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6 Reservation of Shares. The Company will at all times reserve and keep
available out of its authorized but unissued common stock, solely for issuance,
sale and delivery upon the exercise or conversion of this Warrant, a number of
shares of common stock equal to the number of shares of common stock issuable
upon the exercise of this Warrant.


                                      - 3 -

<PAGE>



     2.7 Fractional Shares. No fractional shares shall be issuable upon exercise
or conversion of the Warrant and the number of Shares to be issued shall be
rounded down to the nearest whole Share. If a fractional share interest arises
upon any exercise or conversion of the Warrant, the Company shall eliminate such
fractional share interest by paying Holder amount computed by multiplying the
fractional interest by the fair market value of a full Share.

     2.8 Certificate as to Adjustments. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

ARTICLE 3.  REPRESENTATIONS AND COVENANTS OF THE COMPANY.

     3.1 Representations and Warranties. The Company hereby represents and
warrants to the Holder as follows:

Warrant is not greater than the fair market value of the Shares as of the date

right represented by this Warrant, and all securities, if any, issuable upon
conversion of the Shares, shall, upon issuance, be duly authorized, validly

except for restrictions on transfer provided for herein or under applicable
federal and state securities laws.

"Warrant Price") equal to twenty cents ($.20); as adjusted pursuant to Article 2
of this Warrant, subject to the provisions and upon the terms and conditions set
forth of this Warrant.

ARTICLE 1.  EXERCISE AND EARLY TERMINATION

     1.1 Method of Exercise. Holder may exercise this Warrant by delivering a
duly executed Notice of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the shares being purchased.

     1.2 Conversion Right. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this warrant, in whole or in
part, into a number of shares determined by dividing (a) the aggregate fair
market value of the shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

     1.3 Fair Market Value. If the Shares are traded in a public market, the
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not traded in a public
market, the Board of Directors of the Company shall determine fair market value
in its reasonable good faith judgment. The foregoing notwithstanding, if Holder
advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment

banking firm is greater than that of such investment banking firm shall be paid
by the Company. In all other circumstances, such fees and expenses shall be paid
by Holder.

     1.4 Delivery of Certificate and New Warrant. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction on delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, or surrender and cancellation of this Warrant, the Company
at its expense shall execute dna deliver, in lieu of this Warrant, a new warrant
of like tenor.

     1.6 Repurchase on Sale, Merger, or Consolidation of the Company.

     1.6.1 "Acquisition". For the purpose of this Warrant, "Acquisition" means
any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

     1.6.2 Assumption of Warrant. If upon the closing of any Acquisition the
successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

     1.6.3 Nonassumption. If upon the closing of any Acquisition and successor
entity does not assume the obligations of this Warrant and Holder has not
otherwise exercised this Warrant in full, then the unexercised portion of this
Warrant shall be deemed to have been automatically converted pursuant to Section
1.2 and thereafter Holder shall participate in the acquisition on the same terms
as other holders of the same class of securities of the Company.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES

     2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, subdivides the
outstanding common stock into a greater amount of common stock, or, if the
Shares are securities other than common stock, subdivides the Shares in a
transaction that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive, without cost of Holder, the total number and kind of securities
to which Holder would have been entitled had Holder owned the Shares of record
as of the date the dividend or subdivision occurred.

     2.2 Reclassification, Exchange, or Substitution. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Certificate of Incorporation upon
the closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events.

     2.3 Adjustments for Combinations, Etc. If the outstanding Shares are
Combined or consolidated, by reclassification or otherwise. into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4 Adjustments for Diluting Issuances. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant or, if the Shares are Preferred
Stock, the number of shares of common stock issuable upon conversion of the
Shares, shall be subject to adjustment, from time to time in the manner set
forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit A).

     2.5 No Impairment. The Company shall not, by amendment of its Certificate
of Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6 Reservation of Shares. The Company will at all times reserve and keep
available out of its authorized but unissued common stock, solely for issuance,
sale and delivery upon the exercise or conversion of this Warrant, a number of
shares of common stock equal to the number of shares of common stock issuable
upon the exercise of this Warrant.

     2.7 Fractional Shares. No fractional shares shall be issuable upon exercise
or conversion of the Warrant and the number of Shares to be issued shall be
rounded down to the nearest whole Share. If a fractional share interest arises
upon any exercise or conversion of the

                                      - 3 -

<PAGE>



Warrant, the Company shall eliminate such fractional share interest by paying
Holder amount computed by multiplying the fractional interest by the fair market
value of a full Share.

     2.8 Certificate as to Adjustments. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

                            ANTI-DILUTION PROVISIONS
             (FOR COMMON STOCK WARRANTS WHERE EXERCISE PRICE EQUALS
          PRICE OF PREFERRED STOCK WHICH HAS ANTI-DILUTION PROTECTION)



     In the event of the issuance (a "Diluting Issuance") by the Company, after
the Issue Date of the Warrant, of securities at a price per share less than the
then conversion price of the Company's Series D Preferred Stock, then the number
of Shares issuable upon exercise of the Warrant shall be adjusted as a result of
Diluting Issuances in the same proportion as the number of shares of common
stock issuable upon conversion of the Series D Preferred Stock in accordance
with the Company's Articles (Certificate) of Incorporation which adjust the
conversion price of the Preferred Stock in the event of Diluting Issuances.

     The Company and the Holder agree that the Provisions, as in effect on the
Issue Date, shall be amended to conform to any subsequent amendment, waiver or
termination thereof by the Company's shareholders and shall terminate upon the
conversion of the Preferred Stock.

     Under no circumstances shall the aggregate Warrant Price payable by the
Holder upon exercise of the Warrant increase as a result of any adjustment
arising from a Diluting Issuance.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.


                 AMENDED AND RESTATED WARRANT TO PURCHASE STOCK

Issue Date:  April 6, 1992
Expiration Date:  July 7, 2000
Exercise Price:  $0.22
Number and Class of Stock:  83,333 shares of Common Stock


     THIS AMENDED AND RESTATED WARRANT (the "Warrant") is issued as of the Issue
Date set forth above by DIGITRAN CORPORATION, a Delaware corporation (the
"Company") for the benefit of SILICON VALLEY BANCSHARES (the "Holder").

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, the Holder is entitled to purchase 83,333
fully paid and nonassessable shares of the common stock, $.0025 par value per
share (the "Shares"), of the Company, at the initial exercise price per Share
(the "Warrant Price") as set forth above and as adjusted pursuant to Article 2
of this Warrant, subject to the provisions and upon the terms and conditions set
forth of this Warrant.


ARTICLE 1.  EXERCISE AND EARLY TERMINATION.

     1.1 Method of Exercise. Holder may exercise this Warrant by delivering a
duly executed Notice of Exercise in substantially the form attached as Appendix
1 hereto to the principal office of the Company. This Warrant shall be
exercisable until the Expiration Date. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2 Conversion Right. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.3.

     1.3 Fair Market Value. If the Shares are traded in a public market, the
fair market value of the Shares shall be the closing price of the Shares
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking firm to undertake such valuation. if the valuation of such investment
banking firm is greater than that determined by the Board of Directors, then all
fees and expenses of such investment banking firm shall be paid by the Company.
In all other circumstances, such fees and expenses shall be paid by Holder.


<PAGE>




     1.4 Delivery of Certificate and New Warrant. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.5 Replacement of Warrants. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, or surrender and cancellation of this Warrant, the Company
at its expense shall execute and deliver, in lieu of this Warrant, a new warrant
of like tenor.

     1.6 Repurchase on Sale, Merger, or Consolidation of the Company.

     1.6.1. "Acquisition". For the purpose of this Warrant, "Acquisition" means
any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

     1.6.2. Assumption of Warrant. If upon the closing of any Acquisition the
successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

     1.6.3. Nonassumption. If upon the closing of any Acquisition the successor
entity does not assume the obligations of this Warrant and Holder has not
otherwise exercised this Warrant in full, then the unexercised portion of this
Warrant shall be deemed to have been automatically converted pursuant to Section
1.2 and thereafter Holder shall participate in the acquisition on the same terms
as other holders of the same class of securities of the Company.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES.

     2.1 Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
or, if the Shares are securities other than common stock, subdivides the Shares
in a transaction that increases the amount of common stock into which the Shares
are convertible, then upon exercise of this Warrant, for each Share acquired,
Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend or subdivision occurred.

     2.2 Reclassification, Exchange or Substitution. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Certificate of Incorporation upon
the closing of a registered public offering of the Company's common stock.

                                       -2-

<PAGE>



The Company or its successor shall promptly issue to Holder a new Warrant for
such new securities or other property. The new Warrant shall provide for
adjustments which shall be as nearly equivalent of the new Warrant. The
provisions of this Section 2.2 shall similarly apply to successive
reclassifications, exchanges, substitutions, or other events.

     2.3 Adjustments for Combinations, Etc. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4 Adjustments for Diluting Issuances. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant or, if the Shares are Preferred
Stock, the number of shares of common stock issuable upon conversion of the
Shares, shall be subject to adjustment, from time to time in the manner set
forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit A).

     2.5 No Impairment. The Company shall not, by amendment of its Certificate
of Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6 Reservation of Shares. The Company will at all times reserve and keep
available out of its authorized but unissued common stock, solely for issuance,
sale and delivery upon the exercise or conversion of this Warrant, a number of
shares of common stock equal to the number of shares of common stock issuable
upon the exercise of this Warrant.

     2.7 Fractional Shares. No fractional shares shall be issuable upon exercise
or conversion of the Warrant and the number of Shares to be issued shall be
rounded down to the nearest whole Share. If a fractional share interest arises
upon any exercise or conversion of the Warrant, the Company shall eliminate such
fractional share interest by paying Holder an amount computed by multiplying the
factional interest by the fair market value of a full Share.

     2.8 Certificate as to Adjustments. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.


ARTICLE 3.  REPRESENTATIONS AND COVENANTS OF THE COMPANY.

     3.1 Representations and Warranties. The Company hereby represents
andwarrants to the Holdern as follows:


                                       -3-

<PAGE>



          (a) The initial Warrant Price referenced on the first page of this
     Warrant is not greater than the fair market value of the Shares as of the
     date of this Warrant.

          (b) All Shares which may be issued upon the exercise of the purchase
     right represented by this Warrant shall, upon issuance, be duly authorized,
     validly issued, fully paid and nonassessable, and free of any liens and
     encumbrances except for restrictions on transfer provided for herein or
     under applicable federal and state securities laws.

          (c) The authorized and issued and outstanding capital stock of the
     company is as set forth on Exhibit B. All the outstanding shares of capital
     stock of the Company have been duly authorized, are validly issued and are
     fully paid and nonassessable. Except as set forth in Exhibit B, (i) there
     are no options, warrants or rights to purchase shares of capital stock or
     other securities of the Company authorized, issued or outstanding, nor is
     the Company obligated in any other manner to issue shares of its capital
     stock or other securities; (ii) there are no restrictions on the transfer
     of shares of capital stock of the Company other than those imposed by
     federal and relevant state securities laws; and (iii) no bolder of any
     security of the Company is entitled to preemptive or similar statutory or
     contractual rights, either arising pursuant to any agreement or instrument
     to which the Company is a party, or which are otherwise binding upon the
     Company. Neither the issuance of this Warrant nor the shares of Common
     Stock issued upon any exercise or conversion of this Warrant will result in
     an adjustment under the antidilution or exercise rights of any holders of
     any outstanding shares of capital stock of the Company. The offer and sales
     of all shares of capital stock and other securities of the Company issued
     before the date of this Warrant complied with or were exempt from the
     registration requirements of all federal and state securities laws.

     3.2 Notice of Certain Events. If the Company proposes at any time (a) to
declare any dividend or distribution upon its common stock, whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription pro rata to the holders of any class or series of
its stock any additional shares of stock of any class or series or other rights;
(c) to effect any reclassification or recapitalization of common stock; (d) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (e) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give
Holder (1) at least 20 days prior written notice of the date on which a record
will be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the matters
referred to in (c) and (d) above; (2) in the case of the matters referred to in
(c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of common
stock will be entitled to exchange their common stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

     3.3 Information Rights. So long as the Holder holds this Warrant and/or any
of the Shares, the Company shall deliver to the Holder (a) promptly after
mailing, copies of all notices or other written communications to the
shareholders of the Company, (b) within ninety (90) days after the end of each
fiscal year of the Company, the annual audited financial statements of the
Company certified by independent public accountants of recognized standing and
(c) within forty-five (45) days after the end of each of the first three
quarters or each fiscal year, the Company's quarterly, unaudited financial
statements.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER

                            WARRANT TO PURCHASE STOCK


Corporation:  Digitran Corporation, a Delaware corporation
Number of Shares:  176,667
Class of Stock: Common
Initial Exercise Price: $0.22 per share
Issue Date: July 7, 1995
Expiration Date: July 7, 2000


     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANCSHARES ("Holder") is
entitled to purchase the number of fully paid and nonassessable shares of the
class of securities (the "Shares") of Digitran Corporation, a Delaware
corporation (the "Company") at the initial exercise price per Share (the
"Warrant Price') all as set forth above and as adjusted pursuant to Article 2 of
this Warrant, subject to the provisions and upon the terms and conditions set
forth of this Warrant.


ARTICLE 1  EXERCISE

     1. 1. Method of Exercise. Holder may exercise this Warrant by delivering a
duly executed Notice of Exercise in substantially the form attached as Appendix
1 hereto, to the principal office of the Company. Unless Holder is exercising
the conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2. Conversion Right. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.3.

     1.3. Fair Market Value. If the Shares are traded in a public market, the
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking firm to undertake such valuation. If the valuation of such investment
banking firm is greater than that determined by the Board of Directors, then all
fees and expenses of such investment banking firm shall be paid by the Company.
In all other circumstances, such fees and expenses shall be paid by Holder.



<PAGE>



     1.4. Delivery of Certificate and New Warrant. Promptly after Holder
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.5. Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.6. Repurchase on Sale, Merger, or Consolidation of the Company.

     (a) "Acquisition". For the purpose of this Warrant, "Acquisition" means any
sale, license, or other disposition of all or substantially all of the assets of
the Company, or any reorganization, consolidation, or merger of the Company
where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

     (b) Assumption of Warrant. If upon the closing of any Acquisition the
successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

     (c) Nonassumption. If upon the closing of any Acquisition the successor
entity does not assume the obligations of this Warrant and Holder has not
otherwise exercised this Warrant in full, then the unexercised portion of this
Warrant shall be deemed to have been automatically converted pursuant to Section
1.2 and thereafter Holder shall participate in the acquisition on the same terms
as other holders of the same class of securities of the Company.


ARTICLE 2  ADJUSTMENTS TO THE SHARES

     2.1. Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this Warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as
of the date the dividend or subdivision occurred.

     2.2. Reclassification, Exchange or Substitution. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Certificate of Incorporation upon
the closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property 

                                       -2-

<PAGE>



issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitutions,
or other events.

     2.3. Adjustments for Combinations, Etc. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4. Adjustments for Diluting Issuances. The Warrant Price and the number
of Shares issuable upon exercise of this Warrant shall be subject to adjustment,
from time to time in the manner set forth on Exhibit A in the event of Diluting
Issuances (as defined on Exhibit A).

     2.5. No Impairment. The Company shall not, by amendment of its Certificate
of Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6. Reservation of Shares. The Company will at all times reserve and keep
available out of its authorized but unissued common stock, solely for issuance,
sale and delivery upon the exercise or conversion of this Warrant, a number of
shares of common stock equal to the number of shares of common stock issuable
upon the exercise of this Warrant.

     2.7. Fractional Shares. No fractional shares shall be issuable upon
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share. If a fractional share interest
arises upon any exercise or conversion of the Warrant, the Company shall
eliminate such fractional share interest by paying Holder amount computed by
multiplying the factional interest by the fair market value of a full Share.

     2.8. Certificate as to Adjustments. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.


ARTICLE 3  REPRESENTATIONS AND COVENANTS OF THE COMPANY.

     3.1. Representations and Warranties. The Company hereby represents and
warrants to the Holder as follows:

          (a) The initial Warrant Price referenced on the first page of this
     Warrant is not greater than (i) the price per share at which the Shares
     (or, if more recent, the conversion price per share at which securities
     convertible into the Shares) were last issued in an arms-length transaction
     in which at least $500,000 of the Shares (or securities convertible into
     the Shares) were sold and (ii) the fair market value of the Shares as of
     the date of this Warrant.

          (b) All Shares which may be issued upon the exercise of the purchase
     right represented by this Warrant shall, upon issuance, be duly authorized,
     validly issued, fully paid

                                       -3-

<PAGE>



     and nonassessable, and free of any liens and encumbrances except for
     restrictions on transfer provided for herein or under applicable federal
     and state securities laws.

          (c) The authorized and issued and outstanding capital stock of the
     Company is as set forth on Exhibit B. All the outstanding shares of capital
     stock of the Company have been duly authorized, are validly issued and are
     fully paid and nonassessable. Except as set forth in Exhibit B, (i) there
     are no options, warrants or rights to purchase shares of capital stock or
     other securities of Company authorized, issued or outstanding, nor is the
     Company obligated in any other manner to issue shares of its capital stock
     or other securities; (ii) there are no restrictions on the transfer of
     shares of capital stock of the Company other than those imposed by federal
     and relevant state securities laws; and (iii) no holder of any security of
     the Company is entitled to preemptive or similar statutory or contractual
     rights, either arising pursuant to any agreement or instrument to which the
     Company is a party, or which are otherwise binding upon the Company.
     Neither the issuance of this Warrant nor the shares of Common Stock issued
     upon any exercise of this Warrant will result in an adjustment under the
     antidilution or exercise rights of any holders of any outstanding shares of
     capital stock of the Company. The offer and sales of all shares of capital
     stock and other securities of the Company issued before the date of this
     Warrant complied with or were exempt from the registration requirements of
     all federal and state securities laws.

     3.2. Notice of Certain Events. If the Company proposes at any time (a) to
declare any dividend or distribution upon its common stock, whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription pro rata to the holders of any class or series of
its stock any additional shares of stock of any class or series or other rights;
(c) to effect any reclassification or recapitalization of common stock; (d) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (e) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give
Holder (1) at least 20 days prior written notice of the date on which a record
will be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the matters
referred to in (c) and (d) above; (2) in the case of the matters referred to in
(c) and (d) above at least 20 days prior written notice of the date when the
same will take place (and specifying the date on which the holders of common
stock will be entitled to exchange their common stock for securities or other
property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

     3.3. Information Rights. So long as the Holder holds this Warrant and/or
any of the Shares, the Company shall deliver to the Holder (a) promptly after
mailing, copies of all notices or other written communications to the
shareholders of the Company, (b) within ninety (90) days after the end of each
fiscal year of the Company, the annual audited financial statements of the
Company certified by independent public accountants or recognized standing and
(c) within forty-five (45) days after the end of each of the first three
quarters or each fiscal year, the Company's quarterly, unaudited financial
statements.

     3.4. Registration Under Securities Act of 1933, as amended. The Company
agrees that the Shares shall be subject to the registration rights set forth in
that certain Fourth Investor Rights Agreement dated as of January 12, 1995, by
and among the Company and the persons signatories thereto.
