                                   THE COMPANY

         Shiva is a leader in the design, development, manufacture and sale of
hardware and software products that enable transparent remote connectivity to
enterprise networks from any location having access to switched analog or
digital telephone service. Founded in 1985, Shiva has applied its expertise in
internetworking, personal computer ("PC") software and telephony to pioneer the
"remote node" approach to remote network access. Shiva's remote node solution
enables a remote PC to access an existing network as a fully functional network
node, thereby allowing users to access network resources from their remote PCs
as if they were directly connected to the enterprise network. Shiva servers
enable users to connect to computing resources from home, while traveling, or as
part of a branch office or multi-user worksite.

         The Company has three remote access product lines: (i) the LanRover 
family, introduced in 1992 (including the LanRover Access Switch, introduced 
in 1996), which provides enterprise-wide remote access, (ii) the Integrator, 
introduced in 1994, which provides ISDN (Integrated Services Digital Network) 
LAN-to-LAN (local area network) remote access for enterprises, workgroups and 
the small office, home office (SOHO) market and (iii) the NetModem/E, 
introduced in 1991, which provides remote access for workgroups and the SOHO 
market. These products include server hardware and software, client software 
and network management software. Shiva remote access products enable single-
user dial-in to LANs over analog or digital lines, individual dial-out from 
LANs to other locations and routed LAN-to-LAN dial-up connections. The 
Company's remote access products support all major desktop computing platforms,
including IBM-compatible PCs, Apple Macintoshes and UNIX workstations. The 
Company also has a family of communications server products, including 
ShivaPort, which provides remote access for TCP/IP devices, as well as 
multiprotocol terminal server functionality to connect terminals and printers 
to a LAN.

         Shiva has developed strategic partnerships with computer operating
systems vendors, such as Microsoft, major information systems providers, such as
IBM, Motorola and Hewlett-Packard, and a major communications equipment company,
Northern Telecom Limited. Shiva markets its products in domestic and
international markets through both direct and indirect distribution channels to
reach a wide range of customers.

         On August 22, 1995, the Company acquired Spider Systems Limited
("Spider"), a leading digital internetworking company based in Edinburgh, United
Kingdom, in exchange for approximately 3,923,606 shares of Common Stock (the
"Spider Acquisition"). The acquisition of Spider provides Shiva with a range of
advanced network access products incorporating Wide Area Network (WAN)
technologies such as ISDN, X.25 and Frame Relay, as well as network consulting
services.

         On June 17, 1996, the Company acquired AirSoft, Inc. ("AirSoft"), a
developer of performance enhancement software products and technologies for
remote network computing based in California, in exchange for approximately
691,587 shares of Common Stock (the "AirSoft Acquisition"). The AirSoft
Acquisition enables Shiva to add AirSoft's technologies to its portfolio of
remote access solutions and to complement the market strength of Shiva PPP,
Shiva's OEM client software package that is included in both the Netscape
Navigator Personal Edition and the Microsoft Internet Explorer. Spider and
AirSoft are collectively referred to herein as the "Acquired Companies," and the
Spider Acquisition and the AirSoft Acquisition are collectively referred to as
the "Recent Acquisitions."

         The Company's principal offices are located at 28 Crosby Drive,
Bedford, Massachusetts 01730, and the Company's telephone number is (617)
270-8300.

                     SELECTED CONSOLIDATED FINANCIAL DATA

        The following data as of December 30, 1995 and December 31, 1994 and

consolidated balance sheet at December 30, 1995 and December 31, 1994 and the
related consolidated statements of operations and of cash flows for the three

Price Waterhouse LLP report on the financial statements is based in part on the

of management, include all adjustments, consisting only of normal recurring

"Management's Discussion and Analysis of Financial Condition and Results of 
Operations" and the Company's Consolidated Financial Statements and Notes

Companies had been combined for all periods presented. Spider's results of

respectively.  Airsoft's financial position as of December 31, 1993 through

                                  RISK FACTORS

         An investment in the shares of Common Stock offered hereby involves a
high degree of risk. Prospective investors should carefully consider the
following risk factors, in addition to the other information contained in this
Prospectus and the documents incorporated by reference herein, before
purchasing the shares of Common Stock being offered hereby. This Prospectus and
the documents incorporated by reference herein contain forward-looking
statements that involve risks and uncertainties. For this purpose, any
statements that are not statements of historical fact may be deemed to be
forward-looking statements. Without limiting the foregoing, the words
"believes," "anticipates," "plans," "expects" and similar expressions are
intended to identify forward-looking statements. The Company's actual results
may differ materially from the results discussed in the forward-looking
statements as a result of certain factors, including those set forth in the
following risk factors and elsewhere in this Prospectus.

UNCERTAINTIES RELATING TO THE RECENT ACQUISITIONS

RISKS ASSOCIATED WITH THE INTEGRATION OF THE ACQUIRED COMPANIES

         The successful and timely integration of Shiva and the Acquired
Companies is critical to the future financial performance of the combined
company. The combination of these companies will require, among other things,
continuing integration of the companies' respective product offerings and
coordination of their sales and marketing and research and development efforts.
The diversion of the attention of management created by the integration process,
and any difficulties encountered in the transition process, could have an
adverse impact on the revenues and operating results of the combined company. In
addition, the process of combining these organizations could cause the
interruption of, or a loss of momentum in, the activities of any or all of the
companies' businesses, which could have an adverse effect on their combined
operations. The difficulty of combining the three companies may be increased by
the need to integrate personnel and the geographic distance between the three
companies. Changes brought about by the Recent Acquisitions may cause key
employees to leave. There can be no assurance that the combined company will
retain the employees it wants to retain or that the combined company will
realize any of the other anticipated benefits of the Recent Acquisitions.

RESELLERS, DISTRIBUTORS AND CUSTOMERS

         There can be no assurance that resellers, distributors and present and
potential customers of Shiva will continue their recent buying patterns without
regard to the Recent Acquisitions, and any significant delay or reduction in
orders could have an adverse effect on the Company's near-term business and
results of operations.

TRANSACTION CHARGES

         In connection with the Spider Acquisition, Shiva recorded charges to
operations of approximately $14.0 million in the quarter ended September 30,
1995, the quarter in which the acquisition was consummated. These charges
reflect costs associated with combining the operations of the two companies and
transaction fees and costs incident to the Spider Acquisition. There can be no
assurance that Shiva will not incur additional material charges in subsequent
quarters to reflect costs associated with the Spider Acquisition.

         In connection with the AirSoft Acquisition, Shiva recorded charges to
earnings of approximately $2.0 million in the quarter ended June 29, 1996, the
quarter in which the acquisition was consummated. These charges reflect costs
associated with combining the operations of the two companies and transaction
fees and costs incident to the AirSoft Acquisition. There can be no assurance
that Shiva will not incur additional material charges in subsequent quarters to
reflect costs associated with the AirSoft Acquisition.

ADVERSE EFFECT OF POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS;
SEASONALITY OF RESULTS OF OPERATIONS

         Shiva's quarterly operating results may vary significantly depending on
factors such as the timing of significant orders, the timing of new product
introductions by Shiva and its competitors and the mix of distribution channels
through which Shiva's products are sold. Spider's quarterly operating results
have historically been highly seasonal, with sales and earnings generally
stronger in the six-month period ended March 31 of each year and generally
weaker in the six-month period ended September 30 of each year. There can be no
assurance that Shiva will be able to continue its growth in revenues or sustain
its profitability on a quarterly or annual basis. Revenues can be difficult to
forecast due to the early stage of development of the remote access market and
the fact that the Company's sales cycle, from initial inquiry to trial to
multiple product purchases, varies substantially from customer to customer.
Shiva's expense levels are based, in part, on its expectations as to future
revenues. If revenue levels are below expectations, operating results may be
adversely affected. Moreover,


                                       -7-

<PAGE>   10



Shiva's resellers typically stock significant levels of inventory, and the
Company's revenues may fluctuate based on the level of the resellers'
inventories in any particular quarter.

NEW PRODUCTS AND RAPID TECHNOLOGICAL CHANGE

         The market for Shiva's products is characterized by rapidly changing
technology, evolving industry standards and frequent new product introductions.
Shiva's future success will depend on its ability to enhance its existing
products and to introduce new products and features to meet and adapt to
changing customer requirements and emerging technologies. The Company recently
introduced the LanRover Access Switch, a new high-end remote access switch, and
AccessPort, a new ISDN client router, each in 1996, and any delay by the 
Company in completing the development of these products, or the failure of 
these products to achieve market acceptance, could have a material adverse 
effect on the Company's financial condition or results of operations. In 
addition, there can be no assurance that Shiva will be successful in 
identifying, developing, manufacturing or marketing other new products or 
enhancing its existing products. Also, there can be no assurance that services,
products or technologies developed by others will not render Shiva's products 
or technologies uncompetitive or obsolete.

HIGHLY COMPETITIVE ENVIRONMENT

         The market for remote access products is highly competitive. Shiva
competes with traditional vendors of modems, remote control software, terminal
emulation software and application specific remote access solutions. Shiva also
competes with suppliers of terminal servers, routers, hubs and other data
communications products, and companies offering remote access solutions based on
emerging technologies such as switched digital telephone services. In addition,
Shiva may encounter increased competition from operating system and network
operating system vendors to the extent such vendors include full remote access
capabilities in their products. The Company currently licenses a version of its
client software that can also operate with non-Shiva servers, and there can be
no assurance that the licensing of such software will not enable other vendors
to develop competitive remote access solutions. The Company may also encounter
competition from telephone service providers (such as AT&T or the regional Bell
operating companies) that may offer remote access services through their
telephone networks.

         The typical method of corporate remote access using Shiva's products
involves a remote user establishing a connection directly to a remote access
server located on the corporation's network. This method of remote access could
migrate to one in which the remote user establishes a connection to a public
network, such as the Internet, to which the corporate network is also connected.
Increased competition from remote access service offerings through public
networks could have a material adverse effect on the Company's business.

         The Spider Acquisition has added products to Shiva's portfolio that
compete more directly with those offered by large internetworking and
communications server companies than did Shiva's products prior to the Spider
Acquisition. As a result, the Company is in more direct competition across a
broader product line with these companies, many of whom have substantially
greater resources than Shiva.

         Increased competition could result in price reductions and loss of
market share which would adversely affect Shiva's revenues and profitability.
Many of Shiva's current and potential competitors have greater financial,
marketing, technical and other resources than Shiva. There can be no assurance
that Shiva will be able to continue to compete successfully with its existing
competitors or will be able to compete successfully with new competitors.

RISKS ASSOCIATED WITH INTERNATIONAL REVENUES, REGULATORY STANDARDS AND
FOREIGN CURRENCY EXCHANGE RATE FLUCTUATIONS

         The Company's international revenues accounted for approximately 39%,
47%, 52%, 55% and 57% of total revenues in the first six months of fiscal 1996
and in fiscal 1995, 1994, 1993 and 1992, respectively. In addition to direct
international sales, Shiva also sells products to U.S. original equipment
manufacturers, such as IBM, that sell such products internationally. While many
of Shiva's current products are designed to meet the regulatory standards of
foreign markets, any inability to obtain foreign regulatory approvals with
respect to future

                                       -8-

<PAGE>   11



products on a timely basis could have an adverse effect on operating results. In
addition, Shiva is subject to the usual risks of doing business abroad,
including fluctuations in currency exchange rates, increases in duty rates,
difficulties in obtaining export licenses, difficulties in enforcement of
intellectual property rights and political uncertainties. To the extent that the
Company makes sales denominated in currencies other than U.S. dollars, gains and
losses on the conversion of such sales to U.S. dollars may in the future
contribute to fluctuations in the Company's business and operating results. In
addition, fluctuations in exchange rates could affect demand for the Company's
products.

POTENTIAL VOLATILITY OF STOCK PRICE

         The Company's shares of Common Stock have been listed on the Nasdaq
National Market since November 1994. The market price of the Common Stock has
experienced significant variations during this period, ranging from a high of
$87.25 to a low of $13.25, and there can be no assurance that the market price
of the Common Stock will not experience similar fluctuations in the future or
will not fall below such levels. The market price of the Company's Common Stock
could be subject to wide fluctuations in response to quarter-to-quarter
variations in operating results, changes in earnings estimates by analysts and
market conditions in the industry, as well as general economic conditions. In
addition, the stock market has experienced volatility that has particularly
affected the market prices for many companies' stock and that often has been
unrelated to the operating performance of such companies. These market
fluctuations may adversely affect the market price of the Company's Common
Stock.

RELIANCE ON REMOTE ACCESS MARKET; EARLY STAGE OF MARKET; CLIENT SOFTWARE 
LICENSING STRATEGY

         Shiva currently devotes a significant portion of its research and
development, manufacturing, marketing and sales resources to service the private
and public remote access market and expects to continue to do so. Although Shiva
believes that its concentrated focus provides it with competitive advantages in
the remote access market, this focus also may leave the Company more vulnerable
to a decline in the remote access market than companies with more diverse
product offerings. Moreover, the Company's future financial performance will
depend in large part on continued growth in the remote access market, which in
turn will depend in part on the growth in the number of organizations utilizing
remote access products and the number of applications developed for use with
those products. There can be no assurance that these markets will continue to
grow or that the Company will be able to respond effectively to the evolving
requirements of these markets. Moreover, many of the Company's customers have
not yet standardized upon any particular remote access solution, and there can
be no assurance that Shiva's products will be the standard adopted by its
customers.

         The Company grants unlimited use licenses of its client software, which
operates solely with Shiva servers, as part of each sale of a remote access
server. The Company has implemented a strategy of licensing a version of its
client software that can also operate with non-Shiva servers to third-party
vendors who desire to provide remote access functionality in their own product
offerings. There can be no assurance that the Company will achieve significant
revenues from the licensing of its client software.

POTENTIAL ADVERSE IMPACT OF PRODUCT RETURNS AND PRICE REDUCTIONS

         Shiva provides most of its distributors and resellers with product
return rights for stock balancing or product evaluation. Shiva also provides
most of its distributors and resellers with price protection rights. Stock
balancing rights permit distributors to return products to Shiva for credit
against future product purchases, within specified limits. Product evaluation
rights permit end-users to return products to Shiva, through the distributor or
reseller from whom such products were purchased, within 30 days of purchase if
such end-user is not fully satisfied. Price protection rights require that Shiva
grant retroactive price adjustments for inventories of Shiva products held by
distributors or resellers if Shiva lowers its prices for such products. Revenues
were reduced by provisions for product returns of $3,978,000, $7,410,000,
$7,092,000 and $4,938,000 in the first six months of fiscal 1996 and in
fiscal 1995, 1994 and 1993, respectively. Reserves for product returns were
$4,983,000, $4,581,000, $3,309,000 and $2,054,000 at June 29, 1996,
December 30, 1995, December 31, 1994 and January 1, 1994, respectively.
Although Shiva believes that it has adequate reserves to cover product returns 
and price reductions, there can be

                                       -9-

<PAGE>   12



no assurance that the Company will not experience significant returns or price
protection adjustments in the future or that such reserves will be adequate to
cover such returns and price reductions.

DEPENDENCE ON SUBCONTRACTORS AND SUPPLIERS

         Shiva is dependent on two subcontractors for the manufacture of
significant portions of its remote access products. If these subcontractors were
to become unable or unwilling to continue to manufacture Shiva's key products in
required volumes, the Company would have to identify and qualify acceptable
additional subcontractors. This qualification process could be lengthy and no
assurances can be given that any additional sources will become available to the
Company on a timely basis. In addition, the chipsets used in certain of Shiva's
Token Ring connectivity products and modem products are currently available only
from IBM and Rockwell, respectively. To date, Shiva has not experienced
significant delays in the receipt of key components. Certain of the components
of the Integrator product line are currently available only from Intel, Motorola
and Matra Harris. The inability to obtain sufficient key components as required,
or to develop alternative sources if and as required in the future, could result
in delays or reductions in product shipments which, in turn, could have a
material adverse effect on Shiva's results of operations.

POTENTIAL ADVERSE EFFECT OF ANY INABILITY TO MANAGE GROWTH

         Shiva is currently experiencing a period of rapid growth which has
placed, and could continue to place, a significant strain on its resources. This
strain has been increased by the Recent Acquisitions. If Shiva's management is
unable to manage any future growth effectively, Shiva's results of operations
could be adversely affected.

DEPENDENCE ON HIGHLY-SKILLED PERSONNEL

         Shiva believes that its future success will also depend in large part
upon its ability to attract and retain highly skilled technical, managerial and
marketing personnel including, in particular, additional management personnel in
the areas of research and development and technical support. Competition for
such personnel is intense. There can be no assurance that Shiva will be
successful in attracting and retaining the personnel it requires to continue to
grow.

DEPENDENCE ON PROPRIETARY TECHNOLOGY

         Although Shiva believes that its continued success will depend
primarily on continuing innovation, sales, marketing and technical expertise,
the quality of product support and customer relations, Shiva must also protect
the proprietary technology contained in its products. Shiva does not currently
hold any patents, relying instead on a combination of copyright, trademark,
trade secret laws and contractual provisions to establish and protect
proprietary rights in its products. There can be no assurance that the steps
taken by Shiva in this regard will be adequate to deter misappropriation or
independent third-party development of its technology. Although Shiva believes
that its products and technology do not infringe proprietary rights of others,
there can be no assurance that third parties will not assert infringement claims
or that Shiva will not be required to obtain licenses of third-party
technologies.

ADVERSE EFFECT OF FLUCTUATIONS IN ECONOMIC AND MARKET CONDITIONS

         The demand for Shiva's products depends in large part upon the general
demand for computer networks. General demand for computing related equipment
fluctuates from time to time based on numerous factors, including capital
spending levels and general economic conditions. The market for remote access
products is relatively new, and therefore Shiva believes that current economic
conditions have not had an adverse effect on its business. However, there can be
no assurance that future declines of computer and related equipment sales, as a
result of general economic conditions, or any other reason, would not have an
adverse effect on the Company's results of operations.

SHARES ELIGIBLE FOR FUTURE SALE

         Sales of substantial numbers of shares of the Company's Common Stock in
the public market could adversely affect the market price of the Common Stock.

POTENTIAL ADVERSE EFFECTS OF ANTI-TAKEOVER PROVISIONS; RIGHTS PLAN; POSSIBLE 
ISSUANCE OF PREFERRED STOCK

         The Company's Restated Articles of Organization and Restated By-laws
contain provisions that may make it more difficult for a third party to acquire,
or discourage acquisition bids for, the Company. Moreover, the Company is
subject to an anti-takeover provision of the Massachusetts General Laws which
prohibits, subject to certain exceptions, a holder of 5% or more of the
outstanding voting stock of the Company from engaging in certain activities with
the Company, including a merger, stock or asset sale. These provisions could
limit the price that certain investors might be willing to pay in the future for
shares of the Company's Common Stock. In addition, the Company has adopted a
Rights Plan pursuant to which the Company has distributed to its stockholders
rights to purchase shares of junior participating preferred stock. Upon certain
triggering events, such rights become exercisable to purchase the Company's
Common Stock at a price substantially discounted from the then applicable market
price of the Company's Common Stock. The Rights Plan could have the effect of
discouraging a merger or tender offer involving the securities of the Company
that is not approved by the Company's Board of Directors by increasing the cost
of effecting any such transaction and, accordingly, could have an adverse impact
on stockholders who might want to vote in favor of such merger or participate in
such tender offer. Also, shares of the Company's Preferred Stock may be issued
in the future without further stockholder approval and upon such terms and
conditions, and having such rights, privileges and preferences, as the Board of
Directors may determine. The rights of the holders of Common Stock will be
subject to, and may be adversely affected by, the rights of any holders of
Preferred Stock that may be issued in the future. The issuance of Preferred
Stock, while providing desirable flexibility in connection with possible
acquisitions and other corporate purposes, could have the effect of making it
more difficult for a third party to acquire, or discouraging a third party from
acquiring, a majority of the outstanding voting stock of the Company. The
Company has no present plans to issue any shares of Preferred Stock, although
shares of Preferred Stock are reserved for issuance under the Rights Plan.


                                 USE OF PROCEEDS

         The Company will not receive any of the proceeds from the sale of the
Shares of Common Stock by the Selling Stockholders.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

     The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Company's
Consolidated Financial Statements and Notes thereto.

OVERVIEW

     The Company was incorporated in 1985 and initially specialized in the
development of networking products for AppleTalk LANs (local area networks). In
late fiscal 1991, the Company began a transition toward the sale of remote
access products with the introduction of NetModem/E, its first multiplatform,
multiprotocol remote access product for workgroups. In fiscal 1992, the Company
continued its strategic shift towards remote access products and introduced its
LanRover product line, a multiport, enterprise-wide remote access solution. In
fiscal 1993, the Company established an OEM relationship with IBM, resulting in
the release of IBM's 8235 product, a LanRover server customized for IBM
environments. In fiscal 1994, the Company introduced the LanRover/PLUS server
and released LanRover 3.0 server, which provides multiprotocol capability. In
fiscal 1995, the Company continued to focus on its core remote access products
including a new software release for its LanRover and NetModem product lines,
Release 3.5, and broadened its base of strategic partners by establishing
relationships with Hewlett-Packard ("HP"), Motorola and Northern Telecom Limited
("Nortel").

     In August 1995, the Company acquired Spider Systems Limited ("Spider"), a
leading digital internetworking company based in Edinburgh, U.K., through the
issuance of approximately 3,923,606 shares of its common stock (the "Spider
Acquisition"). The Spider Acquisition has been accounted for as a pooling of
interests. Therefore, the consolidated financial statements for all periods
presented have been restated to include the financial results of Spider.
Spider's results of operations in the years ended March 31, 1995 and 1994 have
been combined with Shiva's results of operations in fiscal 1994 and 1993,
respectively. Spider's results of operations in the twelve-month period ended
December 30, 1995 have been combined with Shiva's results of operations in
fiscal 1995. Spider's unaudited results of operations in the three-month period
ended March 31, 1995 have therefore been included in the Company's results of
operations in fiscal 1994 and fiscal 1995. See Note 1 of Notes to Consolidated
Financial Statements.

     As a result of the Spider Acquisition, Shiva acquired technologically
advanced network access hardware and software products. These products connect
remote LANs and individual users to a corporate network, facilitating network
access using advanced switched digital communication protocols such as ISDN,
X.25 and Frame Relay. These products include the ShivaIntegrator product line,
communications servers and communications software. The ShivaIntegrator product
line provides switched digital LAN-to-LAN remote access for enterprises and
workgroups. Communications servers provide remote access for TCP/IP devices and
multiprotocol terminal server functionality to connect terminals and printers to
a LAN. In addition to these product offerings, Shiva now provides network
integration services and also sells, installs and supports products manufactured
by the Company and third parties.

     In June 1996, the Company issued approximately 691,587 shares of its common
stock in exchange for all the outstanding shares of AirSoft, Inc. (the "AirSoft
Acquisition"). AirSoft, Inc. ("AirSoft") designs, manufactures and sells
performance enhancement software products. The AirSoft Acquisition has been
accounted for as a pooling of interests, and therefore the consolidated
financial

                                      -12-

<PAGE>   15
statements for all periods prior to the AirSoft Acquisition have been restated
to include the accounts and operations of AirSoft with those of the Company.

     The Company derives its revenues from remote access products, other
communications products and services. Remote access products include the
LanRover, ShivaIntegrator and NetModem product lines. Other communications
products include communications servers, third-party products (including those
of 3Com), AppleTalk product, and communications software. The Company also 
provides a wide range of service offerings which include network integration 
and training and maintenance services.

SIX-MONTH PERIOD ENDED JUNE 29, 1996 COMPARED WITH THE SIX-MONTH PERIOD ENDED
JULY 1, 1995.

RESULTS OF OPERATIONS

     REVENUES. Revenues increased by 82%, to $94,794,000, for the six-month
period ended June 29, 1996, from $52,113,000 in the comparable period in fiscal
1995. This increase was principally due to higher revenues from the Company's
remote access products. Remote access product revenues increased by 136%, to
$79,016,000, in the six-month period ended June 29, 1996, from $33,497,000
during the comparable period in fiscal 1995, principally due to higher revenues
from the Company's LanRover product family, including the LanRover AccessSwitch.
Sales to OEM customers accounted for 20% of revenues in the six months ended
June 29, 1996 and were not significant in the comparable period in fiscal 1995.
These increases were partially offset by a 24% decline in revenues from the
Company's other communications products. The Company anticipates that revenues
from other communications products will continue to decline and will account for
a decreasing percentage of revenue in future periods. The Company provides its
distributors and resellers with product return rights for stock balancing and
product evaluation. Revenues were reduced by provisions for product returns of
$3,978,000 and $4,077,000 in the six month periods ended June 29, 1996 and July
1, 1995, respectively, representing 4% and 7% of gross revenues, respectively.
International revenues increased to $37,247,000, or 39% of revenues, in the
six-month period ended June 29, 1996, from $27,259,000, or 52% of revenues, in
the comparable period in fiscal 1995.

     GROSS PROFIT. Gross profit increased as a percentage of revenues to 59% in
the six-month period ended June 29, 1996, compared to 57% for the comparable
period in fiscal 1995. This increase was primarily attributable to increased
revenues from the Company's LanRover product family, which carry higher gross
margins than the Company's other products, partially offset by increased
revenues from lower gross margin OEM remote access products.

     RESEARCH AND DEVELOPMENT. Research and development expenses increased to
$10,656,000, or 11% of revenues, in the six-month period ended June 29, 1996,
from $6,356,000, or 12% of revenues, during the comparable period in fiscal
1995. The absolute increase in these expenses was primarily due to the hiring of
additional research and development staff. Research and development expenses
during the six-month period ended June 29, 1996 related primarily to continued
enhancement and development of the Company's remote access products, including
the LanRover Access Switch and the Shiva AccessPort, a new ISDN client router.
Customer-funded development fees reimbursed to the Company, which are reflected
as an offset to research and development expenses, were $851,000 in the
six-month period ended June 29, 1996, compared to $515,000 for the comparable
period in fiscal 1995. Capitalized software development costs were $593,000 in
the six-month period ended June 29, 1996, compared to $264,000 in the comparable
period in fiscal 1995.

     SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative
expenses increased to $31,506,000 for the six-month period ended June 29, 1996,
from $20,032,000 for the comparable period in fiscal 1995. These expenses
represented 33% and 38% of revenues in the six-month periods ended June 29, 1996
and July 1, 1995, respectively. The absolute increase in expenses was primarily
due to worldwide expansion of the Company's sales, marketing and administrative
operations necessary to support the Company's growth. The Company plans to
further invest in its distribution channels in order to continue its global
market penetration.

     MERGER EXPENSES. In connection with the AirSoft Acquisition, the Company
incurred charges to operations of $1,987,000 in the quarter ended June 29, 1996,
the quarter in which the acquisition was consummated. Such charges include: (a)
transaction costs to effect the acquisition, consisting of financial advisor
fees of $1,350,000 plus $325,000 for legal, regulatory and accounting expenses
and (b) employee severance payments and other miscellaneous expenses of
$312,000. Approximately $778,000 of such expenses were paid in the quarter ended
June 29, 1996, and the remaining $1,209,000 of these charges are expected to be
cash outflows in the third quarter of fiscal 1996.

                                      -15-

<PAGE>   18

     INTEREST INCOME AND EXPENSE. The Company had higher interest income during
the six-month period ended June 29, 1996, due to higher investment balances
related to funds generated by the Company's secondary public offering in
November 1995. Interest expense decreased due to the Company's repayment of the
outstanding debt of Spider Systems, Ltd. assumed as part of the Spider
Acquisition, with the exception of the European Coal and Steel Community Fund
loans, in the third quarter of fiscal 1995.

     INCOME TAX PROVISION. The Company's effective tax rate was 33% for the
six-month period ended June 29, 1996, compared to 41% for the comparable period
in fiscal 1995. The decrease in the effective tax rate for the six-month period
ended June 29, 1996 was due to a reduction in the net deferred tax asset
valuation allowance as a result of certain net operating losses that could now
be realized, partially offset by non-deductible merger expenses.

FISCAL 1995 COMPARED TO FISCAL 1994

     REVENUES. Revenues increased by 46%, to $118,581,000, in fiscal 1995 from
$81,058,000 in fiscal 1994. This increase was principally due to higher revenues
from the Company's remote access products. Remote access product revenues
increased by 87%, to $83,924,000, in fiscal 1995 from $44,825,000 in fiscal
1994, principally due to higher revenues from the Company's LanRover and
ShivaIntegrator products. Sales of OEM products to IBM were 10% and 9% of
revenues in fiscal 1995 and 1994, respectively. These increases were partially
offset by a 13% decline in revenues from the Company's other communications
products. The Company anticipates that revenues from other communications
products will account for a decreasing percentage of revenues in future periods.
The Company provides its distributors and resellers with product return rights
for stock balancing and product evaluation. Revenues were reduced by provisions
for product returns of $7,410,000 in fiscal 1995 and $7,092,000 in fiscal 1994,
representing 6% and 8% of gross revenues in fiscal 1995 and 1994, respectively.
International revenues increased to $55,197,000, or 47% of revenues, in fiscal
1995 from $41,942,000, or 52% of revenues, in fiscal 1994.

     GROSS PROFIT. Gross profit increased as a percentage of revenues to 59% in
fiscal 1995, compared to 57% in fiscal 1994. This increase was primarily
attributable to increased revenues from the Company's LanRover products, which
carry higher gross margins than other communications products, partially offset
by increased European sales of lower priced products through large volume
distributors.

     RESEARCH AND DEVELOPMENT. Research and development expenses increased to
$14,787,000, or 12% of revenues, in fiscal 1995 from $9,972,000, or 12% of
revenues, in fiscal 1994. The absolute increase in these expenses was primarily
due to the hiring of additional research and development staff. Research and
development expenses during fiscal 1995 related primarily to continued
enhancements of the Company's remote access products, including the
ShivaIntegrator product line and a new software release for its LanRover and
NetModem product lines. Customer-funded development fees reimbursed to the
Company and government funded research and development grants, which are
reflected as an offset to research and development expenses, were $955,000 in
fiscal 1995, compared to $901,000 in fiscal 1994. Capitalized software
development costs were $827,000 in fiscal 1995, compared with $293,000 in fiscal
1994. The Company anticipates continued significant investment in research and
development.

                                      -16-
<PAGE>   19

     SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative
expenses increased to $44,662,000, or 38% of revenues, in fiscal 1995 from
$32,427,000, or 40% of revenues, in fiscal 1994. The absolute increase in
expenses was primarily due to expansion of the Company's worldwide sales and
support operations, as the Company continued to build its distribution channels.
The Company plans to further invest in its distribution channels in order to
continue its global market penetration.

     MERGER EXPENSES. In connection with the Spider Acquisition, the Company
incurred charges to operations of approximately $13,986,000 in the quarter ended
September 30, 1995, the quarter in which the Spider Acquisition was consummated.
Such charges include: (a) transaction costs to effect the acquisition,
consisting of $2,619,000 for financial advisor fees plus $3,656,000 for legal,
regulatory and accounting fees, printing expenses and other miscellaneous
expenses; (b) employee severance payments of $1,482,000 and phantom stock
compensation of $2,644,000 and (c) $3,585,000 for the integration of operational
activities of the companies, including elimination of duplicative assets,
employee relocation and travel, and the marketing costs related to the
introduction of the combined entity. In fiscal 1995, approximately $10,220,000
million of these expenses were funded from existing cash and short-term
investment balances. Phantom stock compensation and the elimination of
duplicative assets, totaling $3,766,000, were non-cash transactions in this
period.

     INTEREST INCOME AND EXPENSE. The Company had higher interest income in
fiscal 1995, due to investment balances related to funds generated by the
Company's public stock offerings in November 1995 and November 1994. Interest
expense consists primarily of interest incurred on the Company's mortgage on its
European headquarters and capitalized lease obligations.

     INCOME TAX PROVISION. The Company had an income tax provision of $2,386,000
in fiscal 1995, despite a pre-tax loss, primarily due to non-tax deductible
merger costs incurred in connection with the Spider Acquisition. The Company's
effective tax rate was 31% in fiscal 1994.

FISCAL 1994 COMPARED TO FISCAL 1993

     REVENUES. Revenues increased by 32%, to $81,058,000, in fiscal 1994, from
$61,262,000 in fiscal 1993. This increase was principally due to higher revenues
from the Company's remote access products. Remote access product revenues
increased by 119%, to $44,825,000, in fiscal 1994 from $20,510,000 in fiscal
1993, principally due to higher unit sales and average selling prices of the
Company's LanRover and ShivaIntegrator products. Sales of OEM products to IBM,
which began in the second half of fiscal 1993, also contributed significantly to
this increase. These increases in remote access product revenues were partially
offset by a 21% decline in revenues from the Company's other communications
products. The Company provides its distributors and resellers with product
return rights for stock balancing and product evaluation. Revenues were reduced
by provisions for product returns of $7,092,000, or 8% of gross revenues, in
fiscal 1994 and $4,938,000, or 7% of gross revenues, in fiscal 1993.
International revenues increased to $41,942,000, or 52% of revenues, in fiscal
1994 from $33,974,000, or 55% of revenues, in fiscal 1993.

     GROSS PROFIT. Gross profit increased as a percentage of revenues to 57% in
fiscal 1994, compared to 54% in fiscal 1993. This improvement was primarily
attributable to increased revenues from LanRover products, which carry higher
gross margins than the Company's other communications products, increased prices
on certain products and cost reductions. This improvement was partially offset
by increased revenues from lower gross margin OEM remote access products.

                                      -17-
<PAGE>   20

     RESEARCH AND DEVELOPMENT. Research and development expenses increased to
$9,972,000, or 12% of revenues, in fiscal 1994 from $8,162,000, or 13% of
revenues, in fiscal 1993. Research and development expenses in fiscal 1994
related primarily to continued enhancements of the Company's remote access
products, including LanRover 3.0, released in June 1994, and LanRover/PLUS,
released in March 1994 and continued enhancements of ShivaIntegrator products.
Customer funded development fees reimbursed to the Company and government funded
research and development grants, which are reflected as an offset to research
and development expenses, were $901,000 in fiscal 1994, compared to $1,438,000
in fiscal 1993.

     SELLING, GENERAL AND ADMINISTRATIVE. Selling, general and administrative
expenses increased to $32,427,000, or 40% of revenues, in fiscal 1994 from
$23,367,000, or 38% of revenues, in fiscal 1993. The absolute increase in
expenses was due primarily to expansion of the Company's worldwide sales
operation, as the Company continued to build its distribution channels.

     INTEREST INCOME AND EXPENSE. The Company had interest income in fiscal 1994
due to investment balances related to funds generated by the Company's initial
public offering in November 1994. Interest expense consists primarily of
interest incurred on the Company's mortgage on its European headquarters, its
line of credit and capitalized lease obligations.

     INCOME TAX PROVISION (BENEFIT). The Company's effective tax rate was 31% in
fiscal 1994 compared to 42% in fiscal 1993. The decrease in the effective tax
rate was primarily due to a reduction in the net deferred tax asset valuation
allowance and increased research and development credits.

FOREIGN CURRENCY FLUCTUATIONS

A substantial portion of the Company's international revenues is denominated in
currencies other than the U.S. dollar and is consequently subject to foreign
exchange fluctuations. The net income impact of such fluctuations, however, is
offset to the extent expenses of the Company in international operations are
incurred in the same currencies as its revenues. Foreign currency fluctuations
did not have a significant impact on the comparison of the results of operations
for the periods presented.

LIQUIDITY AND CAPITAL RESOURCES

     As of June 29, 1996, the Company had $95,233,000 of cash and cash
equivalents and $4,992,000 of short-term investments. Working capital increased
to $117,882,000 at June 29, 1996 from $109,376,000 at December 30, 1995.

     Net cash provided by operations totaled $5,616,000 for the six-month period
ended June 29, 1996, compared with net cash provided by operations of $4,418,000
during the comparable period in fiscal 1995. Net cash provided by operations
during the six-month period ended June 29, 1996 consisted primarily of net
income adjusted for non-cash expenses including depreciation and amortization,
and increased current liabilities, partially offset by increased accounts
receivable and inventories. The increase in accounts receivable was due to
increased revenue levels. The increase in inventories is necessary to support
the Company's revenue growth and the introduction of the LanRover Access Switch
product.

     Net cash used by investing activities totaled $4,435,000 for the six-month
period ended June 29, 1996, compared to $12,875,000 during the comparable period
in fiscal 1995. Investment activity in the six months ended June 29, 1996
consisted primarily of purchases of property and equipment to support the
Company's growth, partially offset by proceeds from short-term investments upon
maturity. Investment activity for the comparable period in fiscal 1995 consisted
primarily of purchases of short-term investments and property, plant and
equipment.

     Net cash provided by financing activities, which consisted of proceeds from
stock option exercises, partially offset by payments on long-term debt and
capital lease obligations, totaled $899,000 for the six-month period ended June
29, 1996. Net cash used by financing activities was $1,084,000 during the
comparable period in fiscal 1995, and consisted primarily of payments on the
Company's outstanding debt and capital lease obligations.

     The Company has a $5,000,000 unsecured revolving credit facility with a
bank which expires in June 1997. Borrowings under the revolving credit facility
bear interest at the bank's prime rate. The terms of the Credit Agreement
require the Company to maintain a minimum level of profitability and specified
financial ratios. The Company had no borrowings outstanding under this line at
June 29, 1996. The Company also has a foreign credit facility of approximately
$1,552,000, of which approximately $587,000 was available at June 29, 1996.
Available borrowings under this facility are decreased by the value of the
outstanding debt payable to the European Coal and Steel Community Fund and
guarantees on certain foreign currency transactions. The terms of the foreign
credit facility require the Company to maintain a minimum level of profitability
and specified financial ratios. There were no borrowings outstanding under this
foreign credit facility at June 29, 1996.

     The Company enters into forward exchange contracts to hedge against certain
foreign currency transactions for periods consistent with the terms of the
underlying transactions. The forward exchange contracts have maturities that do
not exceed one year. At June 29, 1996, the total amount of forward exchange
transactions covered by hedging contracts was $17,020,000.

     The Company believes that its existing cash and short-term investment
balances, together with borrowings available under the Company's bank credit 
facilities, are sufficient to meet the Company's cash requirements for the 
foreseeable future.

RECENTLY ENACTED ACCOUNTING PRONOUNCEMENTS

     In October 1995, the Financial Accounting Standards Board issued Statement
No. 123, "Accounting for Stock-Based Compensation" (SFAS 123), which
establishes a fair-value-based method of accounting for employee stock-based
compensation plans. However, it allows companies to continue to apply the
intrinsic value method based on APB No. 25, provided certain pro forma
disclosures are made (including net income and earnings per share) as if the
fair-value-based method had been applied. The Company will be required to
implement SFAS 123 in fiscal 1996 and will adopt this standard through the pro
forma disclosure method.

FACTORS THAT MAY AFFECT FUTURE RESULTS

     From time to time, information provided by the Company or statements made
by its employees may contain `forward-looking' information which involve risks
and uncertainties. In particular, statements contained in the Management's
Discussion and Analysis of Financial Condition and Results of Operations which
are not historical facts (including, but not limited to, statements concerning
anticipated operating expense levels and the availability of funds to meet cash
requirements) may be `forward-looking' statements. The Company's actual future
results may differ significantly from those stated in any forward-looking
statements. Factors that may cause such differences are discussed more fully
above under the caption "Risk Factors" and in the Company's Annual Report to
Stockholders, Form 10-K and the Company's other Securities and Exchange
Commission filings.

(1)     Of the total shares of Common Stock listed as owned by the Selling 
        Stockholders, an aggregate of 69,157 shares are held in an escrow 
        account to secure indemnification obligations of the AirSoft 
        stockholders to the Company. It is expected that these shares (less any
        shares which may be distributed from the escrow account to the Company
        in satisfaction of indemnification claims) will be released from escrow
        and distributed to these Selling Stockholders on March 31, 1997. The
        number of shares indicated as owned by each Selling Stockholder 
        includes those shares (representing 10% of the number of shares listed
        as beneficially owned by such Selling Stockholder) which such Selling 
        Stockholder is entitled to receive upon distribution of these shares 
        from the escrow account. The number of shares reflected in each of these
        columns does not take account of any sales of shares by the individuals
        listed since the Registration Statement to which this Prospectus relates
        was declared effective by the Securities and Exchange Commission 
        on __________, 1996.

(2)     John C. Power served as a director of AirSoft prior to its acquisition
        by the Company.

(3)     Jagdeep Singh served as President of AirSoft prior to its acquisition
        by the Company.

(4)     Anthony Sun, an affiliate of Venrock Associates and Venrock Associates
        II, L.P., served as a director of AirSoft prior to its acquisition by
        the Company.

(5)     Roger Evans and Howard Cox, affiliates of Greylock Equity Limited 
        Partnership, served as directors of AirSoft prior to its acquisition
        by the Company.

</TABLE>


        On June 16, 1996, the Company entered into an agreement to acquire
AirSoft, a developer of performance enhancement software products and
technologies for remote network computing based in California, through the
issuance of approximately 691,587 shares of its Common Stock plus the assumption
of stock options exercisable for approximately 119,076 shares of Common Stock.
The AirSoft Acquisition was completed on June 17, 1996, and has been accounted
for as a pooling of interests. Approximately 69,155 of the 691,587 shares of
Common Stock issued in the AirSoft Acquisition were placed in escrow to satisfy
any indemnification claims brought by Shiva based on a breach of any of the
representations and warranties relating to the business of AirSoft.

        The Agreement and Plan of Merger dated as of June 16, 1996 by and among
the Company, a wholly-owned subsidiary of the Company and AirSoft (the "Merger
Agreement") grants certain stockholders of AirSoft certain registration rights
for the Common Stock of the Company issued pursuant to the AirSoft Acquisition.
The Company is fulfilling its obligations under the terms of the Merger
Agreement with respect to such registration rights in connection with the
registration of the Shares being offered pursuant to this Prospectus.

        The AirSoft Acquisition is more fully described in the Company's Current
Report on Form 8-K dated as of June 28, 1996, as amended by the Company's
Current Reports on Form 8-K/A dated as of July 8, 1996 and August 13, 1996.

                              PLAN OF DISTRIBUTION

        The Shares offered hereby are being sold by the Selling Stockholders for
their own accounts. The Company will receive none of the proceeds from this
offering.

        The Shares covered by this Prospectus may be sold by the Selling
Stockholders or by pledgees, donees, transferees or other successors in
interest. Such sales may be made at fixed prices that may be changed, at market
prices prevailing at the time of sale, at prices related to such prevailing
market prices, or at negotiated prices. The Shares may be sold by one or more of
the following: (a) one or more block trades in which a broker or dealer so
engaged will attempt to sell all or a portion of the Shares held by a Selling
Stockholder as agent but may position and resell a portion of the block as
principal to facilitate the transaction; (b) purchases by a broker or dealer as
principal and resale by such broker or dealer for its account pursuant to this
Prospectus; and (c) ordinary brokerage transactions and transactions in which
the broker solicits purchasers. The Selling Stockholders may effect such
transactions by selling shares to or through broker-dealers, and such
broker-dealers will receive compensation in negotiated amounts in the form of
discounts, concessions, commissions or fees from the Selling Stockholders and/or
the purchasers of the shares for whom such broker-dealers may act as agent or to
whom they sell as principal, or both (which compensation to a particular
broker-dealer might be in excess of customary commissions). Such brokers or
dealers or other participating brokers or dealers and the Selling Stockholders
may be deemed to be "underwriters" within the meaning of the Securities Act, in
connection with such sales, and any profits realized by the Selling Stockholders
and compensation of such brokers or dealers may be deemed to be underwriting
discounts and commissions.

        Any securities covered by this Prospectus that qualify for sale pursuant
to Rule 144 under the Securities Act may be sold under Rule 144 rather than
pursuant to this Prospectus.

        The Company intends to maintain the effectiveness of this Prospectus
through the earlier of June 17, 1998 or the date on which all of the Shares
offered hereby have been sold by the Selling Stockholders; provided, however,
that if at certain times the Company is in possession of material nonpublic
information that it determines in good faith that it is not advisable to
disclose in a registration statement but which information would otherwise be
required by the Securities Act to be disclosed in a registration statement,
then Shiva may by written notice immediately suspend the right of the Selling
Stockholders to sell shares pursuant to this registration statement.

        The Merger Agreement provides, with respect to the registration rights
thereunder, that the Company will indemnify the Selling Stockholders for any
losses incurred by them in connection with actions arising from any untrue
statement of a material fact in the Registration Statement or any omission of a
material fact required therein, unless such statement or omission was made in
reliance on written information furnished to the Company by the Selling
Stockholders. Similarly, each Selling Stockholder will indemnify the Company and
its officers and directors for any losses incurred by them in connection with
any actions arising from any untrue statement of material fact in the
Registration Statement or any omission of a material fact required therein, if
such statement or omission was made in reliance on written information furnished
to the Company by such Selling Stockholders. Insofar as indemnification for
liabilities arising under the Securities Act may be permitted to directors,
officers or persons controlling the registrant pursuant to the foregoing
provisions, the registrant has been informed that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act and is therefore unenforceable.

        The Company will inform the Selling Stockholders that the
antimanipulative rules under the Exchange Act (Rules 10b-6 and 10b-7) may
apply to sales in the market and will furnish upon request the Selling 
Stockholders with a copy of these Rules. The Company will also inform the 
Selling Stockholders of the need for delivery of copies of this Prospectus.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and
Stockholders of Shiva Corporation

In our opinion, based upon our audits and the reports of other auditors, the
accompanying consolidated balance sheet and related consolidated statements of  
operations, of changes in stockholders' equity and of cash flows present
fairly, in all material respects, the financial position of Shiva Corporation
and its subsidiaries at December 30, 1995 and December 31, 1994, and the
results of their operations and their cash flows for each of the three years in
the period ended December 30, 1995, in conformity with generally accepted
accounting principles. 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 did not audit the financial
statements of Spider Systems Limited, a wholly-owned subsidiary, for fiscal 
1994, which statements reflect total revenues of $31,735,000 for the year ended
March 31, 1994 or the financial statements of Airsoft, Inc., a wholly-owned 
subsidiary, which statements reflect total assets of $3,285,000 and $2,795,000
at December 31, 1995 and 1994, respectively, and total revenues of $860,000, 
$87,000 and $3,000 for the years ended December 31, 1995, 1994, and 1993, 
respectively. Those statements were audited by other auditors whose reports 
thereon have been furnished to us, and our opinion expressed herein, insofar 
as it relates to the amounts included for Spider Systems Limited and Airsoft, 
Inc. as of and for the periods described above, is based solely on the reports
of the other auditors. We conducted our audits of these statements in accordance
with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits and the reports of other auditors provide a 
reasonable basis for the opinion expressed above.

                   Notes to Consolidated Financial Statements


1.  NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


       Shiva Corporation (the "Company") designs, develops, manufactures and
sells hardware and software products and services that enable transparent remote
connectivity to enterprise networks from any location having access to switched
analog or digital telephone service. The Company markets its products worldwide
primarily through distributors, resellers and original equipment manufacturers.

A summary of the Company's significant accounting policies follows:

FISCAL YEAR

The Company's fiscal year ends on the Saturday closest to December 31.

PRINCIPLES OF CONSOLIDATION

       The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated. In August 1995, the Company issued
approximately 3,923,606 shares of its common stock in exchange for all the
outstanding shares of Spider Systems Limited ("the Spider Acquisition"). Spider
Systems Limited ("Spider") now operates as a wholly-owned subsidiary of Shiva
under the name of Shiva Europe Limited. The Spider Acquisition has been
accounted for as a pooling of interests, and therefore the consolidated
financial statements for all periods prior to the Spider Acquisition have been
restated to include the accounts and operations of Spider with those of the
Company. Spider's results of operations for the years ended March 31, 1995 and
1994 have been combined with the Company's results of operations for the years
ended December 31, 1994 and January 1, 1994, respectively. The results of
operations for fiscal 1995 are for the twelve months ended December 30, 1995 for
both Shiva and Spider. Spider's financial position as of March 31, 1995 has been
combined with the Company's financial position as of December 31, 1994. Spider's
unaudited results of operations for the three months ended March 31, 1995
included in both the results of operations in fiscal 1994 and fiscal 1995, were
as follows:

       No adjustments to conform accounting methods were required. Certain
amounts have been reclassified with regard to presentation of the financial
information of the two companies. Revenues and net income for each of the
previously separate companies for the periods prior to the Spider Acquisition
are as follows:

       In connection with the Spider Acquisition, the Company incurred charges
to operations of $13,986,000 in the quarter ended September 30, 1995, the

                   Notes to Consolidated Financial Statements



INTERIM FINANCIAL DATA (UNAUDITED)

The interim financial data included in the accompanying consolidated financial
statements and notes thereto is unaudited; however in the opinion of the
Company, the interim financial data include all adjustments, consisting only of
normal recurring adjustments, necessary for a fair statement of the results for
the interim periods. The interim financial data are not necessarily indicative
of the results of operations for a full fiscal year.

USE OF 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 liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

REVENUE RECOGNITION

       Revenue from product sales is recognized upon shipment provided that no
significant Company obligations remain and collection of the related receivable
is probable. The Company provides most of its distributors and resellers with
return rights for stock rotation or product evaluation. The Company also
provides its distributors and resellers with price protection rights. An
allowance for estimated future returns is recorded at the time revenue is
recognized based on the Company's return policies and historical experience.
Although the Company believes it has adequate reserves to cover product returns
and price protection rights, there can be no assurance that the Company will not
experience significant returns or price protection adjustments in the future or
that such reserves will be adequate to cover such returns and price protection
rights. The Company provides a one-year warranty on hardware products and a
ninety-day warranty on software media. A provision is made at the time of sale
for product warranty costs. Accrued warranty costs are included in accrued
expenses in the accompanying financial statements. Revenue from technical
support and product maintenance contracts is deferred and recognized ratably
over the period the services are performed. Revenue from integration contracts
is recognized over the duration of such contracts as work is performed and
defined milestones are attained.

<PAGE>   38
                               SHIVA CORPORATION
                   Notes to Consolidated Financial Statements

       The Company has historically provided customers with a variety of
technical support services, including free services which it is not
contractually obligated to provide. A provision is made at the time of sale for
the cost of such free services. Accrued product support expenses are included in
accrued expenses in the accompanying financial statements.

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

       The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents. The Company
invests its excess cash in U.S. Treasury securities, money market funds of major
financial institutions, high-grade commercial paper and time deposits that are
subject to minimal credit and market risk.

       All of the Company's cash equivalents and short-term investments are
classified as available-for-sale in accordance with Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." The Company's short-term investments at December 30, 1995
include an unrealized gain of $137,000 recorded as a separate component of
stockholders' equity and have various maturity dates through September 1996.
Realized gains or losses on the sale of securities are calculated using the
specific identification method. There were no such realized gains or losses in
fiscal 1995 or 1994.

CONCENTRATION OF CREDIT RISK

       Financial instruments which potentially expose the Company to
concentrations of credit risk include accounts receivable. The Company performs
ongoing evaluations of customers' financial condition and, generally, does not
require collateral. In addition, the Company maintains reserves for potential
credit losses, and such losses, in the aggregate, have not exceeded management
expectations. At December 30, 1995, one customer accounted for 10% of the
accounts receivable balance.

FINANCIAL INSTRUMENTS

       The carrying amounts of the Company's financial instruments, which
include cash and cash equivalents, accounts receivable, short-term debt,
accounts payable, long-term debt and capital lease obligations approximate their
fair value at December 30, 1995 and December 31, 1994.

FORWARD FOREIGN EXCHANGE CONTRACTS

       The Company enters into transactions denominated in foreign currencies
and includes the gain or loss arising from such transactions in results of
operations. The Company enters into foreign exchange contracts to hedge specific
foreign currency denominated receivables, which require the Company at maturity
of the contract to exchange foreign currencies for U.K. Pounds at rates agreed
to at inception of the contracts. The forward exchange contracts have maturities
which do not exceed one year. The Company had approximately $11,253,000 and
$2,163,000 of forward exchange contracts outstanding at December 30, 1995 and
December 31, 1994, respectively. Cash flows from the forward exchange contracts
are classified with the related receivable.

INVENTORIES

       Inventories are stated at the lower of cost or market, cost being
determined using the first-in, first-out method.

                   Notes to Consolidated Financial Statements


       The market for the Company's products is characterized by rapidly
changing technology, evolving industry standards and frequent new product
introductions. There can be no assurance that products or technologies developed
by others will not make the Company's inventories obsolete.

       The Company is currently dependent on two subcontractors for the
manufacture of significant portions of its products. Although the Company
believes that there are a limited number of other qualified subcontract
manufacturers for its products, a change in subcontractors could result in
delays or reductions in product shipments. In addition, certain components of
the Company's products are only available from a limited number of suppliers.
The inability to obtain sufficient key components as required could also result
in delays or reductions in product shipments. Such delays or reductions could
have a material adverse effect on the Company's results of operations.

PROPERTY, PLANT AND EQUIPMENT

       Property, plant and equipment are stated at cost and depreciated using
the straight-line method over the estimated useful lives of the related assets.
Equipment held under capital leases is stated at the lower of the fair market
value of the equipment or the present value of the minimum lease payments at the
inception of the leases and is amortized on a straight-line basis over the
shorter of the lives of the related assets or the term of the leases.
Maintenance and repair costs are expensed as incurred. Gains on sale and
leaseback transactions are amortized to income over the term of the underlying
lease agreements.

RESEARCH AND DEVELOPMENT AND CAPITALIZED SOFTWARE DEVELOPMENT COSTS

       Research and development costs, other than certain software development
costs, are charged to expense as incurred. Software development costs incurred
subsequent to the establishment of technological feasibility, and prior to
general release of the product to the public, are capitalized and amortized to
cost of sales on a straight-line basis over the estimated useful lives of the
related products, generally eighteen to thirty-six months. It is reasonably
possible that the remaining estimated useful lives of the related products could
be reduced in the future due to competitive pressures. Unamortized software
development costs of $703,000 and $246,000 are included in other assets at
December 30, 1995 and December 31, 1994, respectively. Amortization expense was
$370,000, $310,000 and $118,000 in fiscal 1995, 1994 and 1993, respectively.

       The Company receives fees under product development contracts with
certain customers. Product development fees are recorded as a reduction of
research and development costs as work is performed pursuant to the related
contracts and defined milestones are attained. Losses, if any, are provided for
at the time that management determines that development costs will exceed
related fees. Payments received under product development contracts prior to the
completion of the related work and attainment of milestones are recorded as
deferred liabilities. In fiscal 1995, 1994 and 1993, the Company recorded
product development fees of $955,000, $766,000 and $987,000, respectively, and
incurred development costs of $1,135,000, $820,000 and $741,000, respectively,
under such contracts.

       The Company has also received foreign government sponsored grants to fund
qualified research and development activities. Grant income is recorded as a
reduction of research and development costs and was $135,000 and $451,000 in
fiscal 1994 and 1993, respectively. There was no grant income recorded in fiscal
1995.

ADVERTISING COSTS

       Advertising costs, other than certain direct-response advertising costs,
are charged to expense as incurred. The Company has not incurred significant
costs associated with direct-response advertising in fiscal 1995, 1994 and 1993,
and there were no capitalized advertising costs at December 30, 1995 or December
31, 1994. Advertising costs were $3,042,000, $2,589,000 and $1,446,000 in fiscal
1995, 1994 and 1993, respectively.

INCOME TAXES

       The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No.109, "Accounting for Income Taxes", which is
an asset and liability method of accounting for income taxes. Under this method,
deferred tax assets and liabilities are recognized for the expected future tax
consequences, utilizing current tax rates, of temporary differences between the
carrying amounts and the tax bases of assets and liabilities. Deferred tax
assets are recognized, net of any valuation allowance, for the estimated future
tax effects of deductible temporary differences and tax operating loss and
credit carryforwards. Deferred income tax expense represents the change in the
net deferred tax asset and liability balances.

FOREIGN CURRENCY TRANSLATION

       Financial statements of international subsidiaries, where the local
currency is the functional currency, are translated using period-end exchange
rates for assets and liabilities and at average rates during the period for
results of operations. The resulting foreign currency translation adjustments
are included as a separate component of stockholders' equity. For international
subsidiaries where the functional currency is other than the local currency,
monetary assets and liabilities are translated using period-end exchange rates,
nonmonetary assets and liabilities are translated at historical rates and
results of operations are translated at average rates for the period. The
resulting foreign currency translation adjustments are included in results of
operations. Gains or losses resulting from foreign currency transactions are
included in results of operations and were insignificant in fiscal 1995, 1994
and 1993.

NET INCOME (LOSS) PER SHARE


       Net income per share is calculated based on the weighted average number
of common shares and common equivalent shares assumed outstanding during the
period. Net loss per share excludes common equivalent shares because the effect
is antidilutive. Pursuant to Securities and Exchange Commission Staff Accounting
Bulletin No. 83, certain common and common equivalent shares issued by the
Company during the twelve months immediately preceding the initial filing of the
registration statement relating to the Company's initial public offering have
been included in the calculation of weighted average shares, using the treasury
stock method and the initial public offering price, as if these shares were
outstanding for all periods prior to the initial public offering.

5.  DEBT

SHORT-TERM DEBT

       Under the terms of a credit agreement (the "Credit Agreement") with a
U.S. bank, the Company has a $5,000,000 unsecured revolving credit facility (the
"Revolver") which bears interest at the bank's prime rate. At December 30, 1995,
available borrowings were reduced by outstanding letters of credit of $881,000
related to certain office leases. These letters of credit expire at various
dates through September 1996. While the Company may repay all or a portion of
the Revolver borrowings at any time, any outstanding principal must be repaid in
full on June 30, 1996. There were no borrowings outstanding under the Revolver
at December 30, 1995 or December 31, 1994. The terms of the Credit Agreement
require the Company to maintain a minimum level of profitability and specified
financial ratios and restrict the payment of cash dividends to stockholders.

       The Company also has a foreign credit facility of approximately
$1,548,000 which is secured by all assets of Shiva Europe Limited. Available
borrowings under this facility are decreased by the value of the outstanding
debt payable to the European Coal and Steel Community Fund. Borrowings under the
foreign credit facility bear interest at the bank's prime rate plus 2.5%. There
were no borrowings outstanding under the foreign credit facility at December 30,
1995. The terms of the foreign credit facility require the Company to maintain
a minimum level of profitability and specified financial ratios.

</TABLE>

       At December 30, 1995, the Company has federal net operating loss
carryforwards of $9,341,000, which expire at various dates through 2010, and
state net operating loss carryforwards of $9,515,000, which expire at various
dates through 2000. The Company also has federal and state research and
development tax credit carryforwards of $1,014,000, which expire at various
dates through 2010. Additionally, the Company has federal alternative minimum
tax credit carryforwards of $77,000, which may be used indefinitely to reduce
regular federal income taxes.
       Ownership changes, as defined in the Internal Revenue Code, may limit the
amount of net operating loss and tax credit carryforwards that can be utilized
to offset future taxable income or tax liability. The amount of the annual
limitation is determined based upon the Company's value immediately prior to the
ownership change. Subsequent significant ownership changes could further affect
the limitation in future years.

                   Notes to Consolidated Financial Statements

         The Company has recorded a deferred tax asset and realized a portion of
the benefits. Realization is dependent on generating sufficient taxable income
prior to expiration of the loss carryforwards. Although realization is not
assured, management believes it is more likely than not that the deferred tax
asset which has been recognized to date will be realized.

         The deferred tax asset valuation allowance increased by $3,806,000 (of
which $3,076,000 related to the tax effect of the exercise of employee stock
options) and decreased by $1,400,000 to recognize the benefit of deferred tax
assets not related to employee stock options which has reduced income taxes
currently payable. Of the total deferred tax asset valuation allowance at
December 30, 1995, $3,976,000 relates to the tax benefit resulting from the
exercise of employee stock options in fiscal 1995 and 1994. The tax benefit,
when realized, will be accounted for as a credit to stockholders' equity rather
than as a reduction in the income tax provision.


7.  STOCKHOLDERS' EQUITY

PREFERRED STOCK

         In connection with the completion of the Company's initial public
offering in November 1994, all shares of convertible preferred stock then
outstanding automatically converted into 7,719,536 shares of common stock.

COMMON STOCK

         On October 21, 1994, the stockholders approved a 1-for-1.5 reverse
split (effective upon the closing of the Company's initial public offering) of
the Company's common stock. All shares and per share amounts included in the
accompanying consolidated financial statements have been adjusted to give
retroactive effect to the reverse stock split for all periods presented. On
November 30, 1995, the stockholders approved an increase in the authorized
shares of common stock from 25,000,000 shares to 50,000,000 shares.

         Each share of common stock entitles the holder to one vote on all
matters submitted to a vote of the Company's stockholders. Common stockholders
are entitled to receive dividends, if any, as may be declared by the Board of
Directors, subject to any preferential dividend rights of any preferred
stockholders.

         In connection with the execution of an equipment sale and leaseback
agreement (See Note 4) in fiscal 1993, the Company issued a warrant for the
purchase of 46,664 shares of the Company's common stock at an exercise price of
$2.25 per share, which expires on July 28, 1998. The common stock purchase
warrant was determined to have an insignificant value on the date of issuance.
In November 1994, the Company issued 29,166 shares of common stock upon partial
exercise of this common stock purchase warrant. In fiscal 1995, the Company
issued the remaining 17,498 shares of common stock related to this common stock
purchase warrant.

8.  STOCK PLANS

1988 STOCK PLAN

         The 1988 Stock Plan (the "1988 Plan") provides for the grant of
incentive stock options and nonqualified stock options, stock awards and stock
purchase rights for the purchase of up to an aggregate of 8,200,000 shares of
the Company's common stock by officers, employees, consultants and directors of
the Company. In fiscal 1995, the Company's stockholders approved increases in
the number of shares issuable under the Plan from 5,333,332 shares to 8,200,000
shares. The Compensation Committee of the Board of Directors is responsible for
administration of the Plan. The Compensation Committee determines the term of
each option, the option exercise price, the number of shares for which each
option is granted and the rate at which each option is exercisable. The Company
may not grant an employee incentive stock options with a fair value in excess of
$100,000 that are first exercisable during any one calendar year.

         Incentive stock options may be granted to any officer or employee at an
exercise price per share of not less than the fair value per common share on the
date of the grant (not less than 110% of the fair value in the case of holders
of more than 10% of the Company's voting stock). Nonqualified stock options may
be granted to any officer, employee, consultant or director at an exercise price
per share of not less than either the book value per common share or 50% of the
fair value per common share on the date of the grant.

         Options granted under the Plan generally expire ten years from the date
of the grant (five years for incentive stock options granted to holders of more
than 10% of the Company's voting stock). The Compensation Committee, at the
request of any optionee, may convert incentive stock options that have not been
exercised at the date of conversion into nonqualified stock options.

         In fiscal 1993, the Company granted options, in lieu of cash payment,
to a consultant of the Company to purchase up to 66,666 shares of common stock
for $.75 per share. The fair value of the services of $25,000 has been included
in selling, general and administrative expenses in fiscal 1993 and additional
paid-in capital has been increased accordingly. All such options were exercised
in fiscal 1994.

         The Company has reserved a total of 5,991,084 shares of common stock
for issuance under the 1988 Stock Plan.

1994 DIRECTOR STOCK OPTION PLAN

         On October 21, 1994, the stockholders approved the 1994 Director Stock
Option Plan (the "Director Plan") under which options to purchase up to an
aggregate of 550,000 shares of the Company's common stock may be granted to
nonemployee directors at an exercise price per share equal to the fair value per
common share on the date of the grant. Under the Director Plan, each nonemployee
director was granted an option to purchase 33,000 common shares (the "initial
shares") on July 17, 1995 and an option to purchase an additional 7,000 common
shares on the third Monday in July of each year thereafter, through December 31,
1999. Eligible directors who have been previously granted stock options under
the 1988 Plan will not be granted an option to purchase the initial shares.

         Twenty-five percent of the options granted under the Director Plan are
exercisable one year from the date of grant and every year thereafter, provided
that the optionee remains a director. Options granted under the Director Plan
generally expire ten years from the date of grant. In fiscal 1995, options to
purchase 99,000 shares of common stock were granted at an exercise price of
$25.63 per share. The Company has reserved 550,000 shares of common stock for
issuance under the Director Plan.

1994 EMPLOYEE STOCK PURCHASE PLAN

         On October 21, 1994 the stockholders approved the 1994 Employee Stock
Purchase Plan (the "1994 Plan") which enables eligible employees to purchase
shares of the Company's common stock. Under the 1994 Plan, eligible employees
may purchase up to an aggregate of 700,000 shares during six-month payment
periods commencing on February 1 and August 1 of each year at a price per share
of 85% of the lower of the market price per share on the first or last business
day of the six-month period. Participating employees may elect to have up to 10%
of regular pay withheld and applied toward the purchase of such shares up to a
maximum of 20,000 shares in any six-month payment period. An employee's rights
under the 1994 Plan terminate upon voluntary withdrawal from the plan at any
time or upon termination of employment. The Company has reserved 678,418 shares
of common stock for issuance under the 1994 Plan.

STOCKHOLDER RIGHTS PLAN

         On September 20, 1995 the Company's Board of Directors adopted a
Stockholders Rights Plan and pursuant thereto declared a dividend of one
preferred stock purchase right for each outstanding share of common stock to
stockholders of record at the close of business on October 13, 1995. Each right
entitles holders of the Company's common stock to purchase one one-hundredth of
a share (a "Unit") of a new series of junior participating preferred stock, $.01
par value per share, at an exercise price of $300.00 per unit, subject to
adjustment. The rights are exercisable and become exercisable for common stock
only under certain circumstances and in the event of particular events relating
to a change in control of the Company. The rights may be redeemed by the Company
under certain circumstances pursuant to the plan. The rights expire on October
13, 2005 unless earlier redeemed or exchanged. The rights have certain
anti-takeover effects, in that they would cause substantial dilution to a person
or group that attempts to acquire a significant interest in the Company on terms
not approved by the Board of Directors.

9.       RETIREMENT PLANS

         The Company sponsors a 401(k) retirement savings plan covering all
domestic employees of the Company who meet minimum age and service requirements.
The plan allows participants to defer a portion of their annual compensation on
a pre-tax basis. The Company matches 50% of the first 3% of each participating
employee's contributions, subject to certain limitations and may, at its
discretion, make additional contributions to the plan. The Company made matching
contributions of $150,000, $119,000 and $76,000, to the plan in fiscal 1995,
1994 and 1993, respectively.

         The Company also sponsors a defined contribution plan for all eligible
European employees of the Company. Participation in the plan is available to
substantially all salaried employees and to certain groups of hourly paid
employees. Company contributions are based on a percentage of the employees'
base salaries. The Company made contributions of $318,000, $267,000 and $226,000
to the plan in fiscal 1995, 1994 and 1993, respectively.

10.      INDUSTRY SEGMENT AND GEOGRAPHIC INFORMATION

         The Company operates in a single industry segment: the development,
manufacture, sale and support of network communications products and services.

         In fiscal 1995, one OEM customer accounted for $11,259,000 (10%) of
revenues. In fiscal 1993, one domestic distributor accounted for $5,905,000
(10%) of revenues.

         Intercompany sales and transfers between geographic areas are accounted
for at prices which are designed to be representative of unaffiliated party
transactions.

Rental expense under operating leases was $1,934,000, $1,877,000 and $1,434,000
in fiscal 1995, 1994 and 1993, respectively.

The Company no longer occupies a property which is leased through March 2014.
The loss on this lease is included in other long-term liabilities.

12.      SUBSEQUENT EVENTS

         On April 2, 1996, the Company's Board of Directors declared a
two-for-one stock split, payable in the form of a stock dividend on all shares
of its Common Stock, which was paid on April 22, 1996 to stockholders of Record
on April 12, 1996. These financial statements and related notes have been
retroactively adjusted, where appropriate, to reflect this two-for-one stock 
split.

         In May 1996, the stockholders of the Company approved (i) an increase
in the number of authorized shares of common stock of the Company from
50,000,000 to 100,000,000 shares and (ii) an increase in the number of shares
available for issuance under the Company's Amended and Restated 1988 Stock Plan
from 8,200,000 to 9,700,000 shares.

         In June 1996, the Company issued approximately 691,587 shares of its
common stock in exchange for all the outstanding shares of Airsoft, Inc. (the
"Airsoft Acquisition"). The Airsoft Acquisition has been accounted for as a
pooling of interests, and therefore the consolidated financial statements for
all periods prior to the Airsoft Acquisition have been restated to include the
accounts and operations of Airsoft, Inc. ("Airsoft") with those of the Company.

         Certain amounts have been reclassified with regard to presentation of
the financial information of the two companies. Revenues and net income (loss)
for each of the previously separate companies for the periods prior to the 
Airsoft Acquisition are as follows:

       In connection with the Airsoft Acquisition, the Company incurred charges
to operations of $1,987,000 in the quarter ended June 29, 1996, the quarter in
which the acquisition was consummated. Such charges include: (a) transaction
costs to effect the acquisition, consisting of financial advisor fees of
$1,350,000 plus $325,000 for legal, regulatory and accounting expenses and (b)
employee severance payments and other miscellaneous expenses of $312,000.

All of the above expenses will be paid by the Company.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Section 67 of Chapter 156B of the Massachusetts General Laws ("Section
67") provides that a corporation may indemnify its directors and officers to the
extent specified in or authorized by: (i) the articles of organization, (ii) a
by-law adopted by the stockholders, or (iii) a vote adopted by the holders of a
majority of the shares of stock entitled to vote on the election of directors.
In all instances, the extent to which a corporation provides indemnification to
its directors and officers under Section 67 is optional. In its Restated
By-Laws, the Company has elected to commit to provide indemnification to its
directors and officers in specified circumstances. Generally, Article V, Section
2 of the Company's Restated By-laws indemnifies directors and officers of the
Company against liabilities and expenses arising out of legal proceedings
brought against them by reason of their status as directors or officers or by
reason of their agreeing to serve, at the request of the Company, as a director
or officer with another organization. Under this provision, a director or
officer of the Company shall be indemnified by the Company for all costs and
expenses (including attorneys' fees), judgments, liabilities and amounts paid in
settlement of such proceedings, liabilities and amounts paid in settlement of
such proceedings, even if he is not successful on the merits, if he acted in
good faith in the reasonable belief that his action was in the best interest of
the Company. The board of directors may authorize advancing litigation expenses
to a director or officer at his request upon receipt of an undertaking by such
director or officer to repay such expenses if it is ultimately determined that
he is not entitled to indemnification for such expenses.

         Article 6 of the Company's Restated Articles of Organization eliminates
the personal liability of the Company's directors to the Company or its
stockholders for monetary damages for breach of a director's fiduciary duty,
except to the extent Chapter 156B of the Massachusetts General Laws prohibits
the elimination or limitation of such liability.

         The "Recommended Offers by Dundas and Wilson CS on behalf of Shiva
Corporation" dated June 16, 1995 (the "Offer Document") provides that the
Majority Stockholders (as defined therein) of Spider will indemnify the Company
and its officers and directors with respect to the statements of the business
and affairs of Spider as set forth in the Offer Document. Any indemnification
pursuant to this section shall be limited to the shares of Common Stock held in
escrow following the closing date. In addition, each Majority Stockholder,
severally and not jointly, has agreed to indemnify the Company and its officers
and directors against and has agreed to hold the Company and its officers and
directors harmless from any and all damage, loss, liability and expense
(including, without limitation, reasonable expenses of investigation and
reasonable attorneys' fees and expenses in connection with any action, suit or
proceeding) ("Loss") incurred or suffered by the Company and its officers and
directors arising out of any misrepresentation or breach of a warranty made by
such Majority Stockholder pursuant to the Agreement and Undertaking dated as of
June 13, 1995, provided that (i) a Majority Stockholder shall only be liable for
any misrepresentations or breaches of warranties made by himself or itself and
(ii) a Majority Stockholder's maximum liability shall not extend beyond the
number of shares of the Company's Common Stock received by such Majority
Stockholder in connection with the Spider Acquisition (including shares of the
Company's Common Stock held in escrow on his or its behalf.) The Registration
Rights Agreement executed in connection with the Spider Acquisition provides for
indemnification by stockholders selling shares of the Company's Common Stock
pursuant to such Registration Rights Agreement of directors, officers and
controlling persons of the Company against certain liabilities, including       
liabilities under the Act, under certain circumstances.


                                      II-1

         The registration rights provisions of the Agreement and Plan of Merger
dated as of June 16, 1996 between the Company, a wholly-owned subsidiary of the
Company and AirSoft (the "Merger Agreement") provides that the former
stockholders of AirSoft will indemnify the Stockholders of the Company and its
directors and officers against certain liabilities, including liabilities under
the Act, under certain circumstances. See "Plan of Distribution."

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, 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, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

         The Company has obtained directors and officer's liability insurance
for the benefit of its directors and certain of its officers.

ITEM 17. UNDERTAKINGS

         (a)      The undersigned Registrant hereby undertakes:

                  (1) To file during any period in which offers or sales are
being made, a post-effective amendment to this Registration Statement:

                         (i) To include any prospectus required by Section 
10(a)(3) of the Securities Act of 1933 (the "Securities Act");

                         (ii) To reflect in the prospectus any facts or events 
arising after the effective date of this Registration Statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in this
Registration Statement. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities
offered would not exceed that which was registered) and any deviation from the
low or high end of the estimated maximum offering range may be reflected in the
form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20% change
in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and

                         (iii) To include any material information with respect
to the plan of distribution not previously disclosed in this Registration
Statement or any material change to such information in this Registration
Statement;

PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the 
Securities Exchange Act of 1934 (the "Exchange Act") that are incorporated by 
reference in this Registration Statement.

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

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

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

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

value per share, of Shiva Corporation, a Massachusetts corporation ("Shiva"),
issued to the former stockholders of AirSoft, Inc. ("AirSoft") pursuant to the

amended, the Restated By-laws of the Company, as amended, and originals, or

Exchange Commission in connection with the Registration Statement.
