                                           ===================================================
</TABLE>

NET PRODUCT REVENUE.  The Company's net product revenue is derived primarily
from the licensing of software products.  Net product revenue also includes
revenue from catalog sales of third party products and catalog advertising
space. The Company sells advertising space in its catalog for cash or receives
third party advertised product.  Revenue for catalog advertising space for cash
sales is recognized the day the catalog is mailed to customers.  Revenue for
third party advertised product received is recognized as each item is sold.
Revenue from catalog advertising sales that was recognized upon sale of third 
party products for the years ended December 31, 1994, 1995 and 1996 was $1.3 
million, $2.4 million and $2.5 million, respectively. Net product revenue
increased 72.0% from 1994 to 1995, and 15.6% from 1995 to 1996, due primarily to
the increase in volume of sales of communications and new network management
software to new customers and to customers upgrading existing licenses. In
addition, net product revenue for the first six months of 1994 includes the
recognition of approximately $1.5 million of product revenue relating to
products shipped in 1993 for which the Company had significant customer
obligations which were satisfied by the shipment of a final product version in
the first quarter of 1994.

OTHER REVENUE.  The Company's other revenue consists of rentals of portions of
the Company's customer lists, royalties received in connection with licensing
ON's software to third parties and maintenance revenue.  Other revenue increased
by 25.9% from 1994 to 1995, and 119.9% from 1995 to 1996.  These increases were
primarily due to an increase in revenue generated from maintenance agreements.

COST OF PRODUCT REVENUE.  Cost of product revenue consists primarily of expenses
associated with product documentation, production and fulfillment costs, and
royalty fees associated with products that are licensed from third party
developers.  In addition, cost of product revenue includes the cost of third
party products resold through the Company's catalog, the cost of
<PAGE>
 
producing the catalog and amortization of purchased intangibles. Cost of product
revenue decreased as a percentage of total revenue from 26.0% in 1994 to 18.6%
in 1995 as catalog revenue decreased as a percentage of total revenue in both
1994 and 1995. The four editions of the Editors' Choice catalog published in
1995 were similar in breadth of product offering to the four editions published
in 1994. The revenue growth of the other product offerings of the Company
significantly outpaced the growth of catalog revenue, as the catalog had
substantially reached its mature revenue level per edition. Cost of product
revenue increased as a percentage of total revenue from 18.6% in 1995 to 23.1%
in 1996. This increase was primarily due to a $571,000 elimination of profit for
inventory previously sold to Technocom, plc, prior to the Company's acquisition
of their LAN software business, a $2.0 million inventory write down related to
the restructuring in the third quarter of 1996, and an increase in product sales
from 1995 to 1996. As part of the Company's restructuring plan and
reorganization of its operations, the Company has decreased its emphasis on the
e-mail business and certain catalog products and has ceased to market, sell,
develop, and support other product lines. As a result, the product inventory
relating to the de-emphasized products, and discontinued product lines were
subsequently identified and written off, all of which is included in cost of
product revenue in the amount of $2.0 million. The product sales related
increase was consistent as a percentage of total revenue from 1995 to 1996.


SALES AND MARKETING EXPENSE.  Sales and marketing expense primarily consists of
compensation paid to sales and marketing personnel, the costs of direct mail and
telemarketing campaigns, and the costs of product trials requested by potential
customers.  Sales and marketing expense also includes the costs of administering
the catalog operation, the costs of public relations, trade shows and
conferences, and the telephone and information technology costs associated with
sales activities. Sales and marketing expense increased as a percentage of total
revenue from 41.9% in 1994 (46.1% excluding the impact of the 1993 deferred
revenue) to 47.6% in 1995 due principally to the Company's investment in its
telemarketing organization in North Carolina.  Sales and marketing expense
decreased slightly as a percentage of total revenue from 47.6% in  1995 to 46.7%
in 1996. This slight decrease is a result of the restructuring of The company,
offset  by the additional sales personnel required to support the growth in the
customer base, the costs associated with the Company's marketing efforts of
existing products, the beginning of ON Technology UK Ltd.'s marketing programs
in Europe, and the launch of the Company's new firewall product, ON Guard.  The
Company anticipates that sales and marketing expense will continue to increase
in absolute dollars as the Company continues to expand direct marketing efforts,
but that sales and marketing expense will remain consistent or decrease as a
percentage of total revenue.


RESEARCH AND DEVELOPMENT EXPENSE.  Research and development expense includes
costs associated with the development of new products, the enhancement of
existing products, and costs associated with providing technical support.
Research and development expense decreased as a percentage of total revenue from
20.4% in 1994 to 15.9% in 1995 primarily as a result of increased licensing of
third party network management software products which more than offset the cost
of continued development of incomplete products acquired from DaVinci in 1994.
Research and development expense increased as a percentage of total revenue from
15.9% in 1995 to 18.3% in 1996. This increase in absolute dollars was primarily
related to the increase in the size of the product portfolio, the associated
costs of product development, enhancements and maintenance, and the additional
costs associated with the Company's acquisitions of neTrend Corporation and
Leprechaun Software International, Ltd. in the first quarter of 1996.  The
Company plans to continue to make significant investments in research and
development.


GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative expense includes
executive compensation, executive support costs, accounting operations,
planning, and business development operations.  General and administrative
expense increased in absolute dollars from $5.3 million in 1994 to $7.0 million
in 1995 due to personnel growth and associated costs, and decreased as a
percentage of total revenue from 9.0% in 1994 to 7.2% in 1995. General and
administrative expense increased in absolute dollars from $7.0 million in 1995
to $9.5 million in 1996 and as a percentage of sales from 7.2% in 1995 to 8.5%
in 1996. The increase reflects personnel growth and associated costs in general
support areas including costs associated with the Company's acquisition of the
LAN software business from Technocom plc in the first quarter of 1996, resulting
in the newly formed ON Technology UK Ltd., and the related expenses of
administering that office.


CHARGE FOR PURCHASED RESEARCH AND DEVELOPMENT.  In connection with the
acquisition of DaVinci in 1994, the Company allocated $4.7 million of the
purchase price to incomplete research and development projects.  In connection
with the acquisitions of neTrend Corporation, Leprechaun Software International,
Ltd. and the LAN Software business from Technocom plc in 1996, the Company
allocated an aggregate of $13.3 million of the respective purchase prices to
incomplete research and development projects.   These costs were expensed as of
the acquisition dates and the allocations represent the estimated fair values
related to the incomplete projects determined by appraisals using appropriate
assumptions and valuation techniques.  The development of these projects had not
yet reached technological feasibility and the technology had no alternative
future use.  The technology acquired in these acquisitions have required
substantial additional development by the Company.  The neTrend technology was
acquired in January 1996 and a limited product based on the acquired technology
was shipped in June 1996.  Development continued in the product throughout 1996
and into 1997. 
<PAGE>
 
The product development investment made by the Company in the neTrend technology
from the date of acquisition is estimated to be approximately $1.7 million. The
Leprechaun technology was acquired in January 1996 and is being developed into
1997. The investment in product development made by the Company in the
Leprechaun technology from the date of acquisition into 1997 is estimated to be
approximately $1.4 million. The research and development projects included in 
the assets purchased from the Technocom plc are not expected to be material to 
the operation of the Company.

CHARGE FOR RESTRUCTURING.  On August 6, 1996, the Company announced that it had
implemented a reorganization of its operations and a restructuring plan (the
"Plan"). The Plan included write-offs and write-downs of certain assets,
including accruing the costs related to a significant reduction in the Company's
work force,  primarily in the technical support and sales and marketing
departments, and the de-emphasis of certain product lines, resulting  in a non-
recurring charge of $5.4 million.  Included in the Plan was an inventory write-
down of $2.0 million which is included in cost of product revenue in accordance
with Emerging Issues Task Force (EITF) 96-9, Classification of Inventory
Markdowns and Other Costs Associated with a Restructuring.

The following are the significant components of the $5.4 million charge for
restructuring:
<TABLE>

Employee severance, benefits and related costs                                    $1.5
 
Write-off and write-down of assets to net realizable value excluding inventory     3.5
 
Provision for lease loss and related costs in closing facility                      .4
                                                                                  ----
                                                                                  $5.4
                                                                                  ==== 
</TABLE>

The employee severance, benefits and related costs includes the costs associated
with the involuntary termination of approximately 100 employees which was
approved as part of the Plan, and communicated to the affected employees on the
day the restructuring was announced, August 6, 1996.  All employee service
required to earn or qualify for the benefits accrued for had been rendered at
August 6, 1996.

The write-down of assets to net realizable value includes the write-off of
certain assets for which there is no future economic benefit to the Company.
These costs include approximately $280,000 of equipment at the facility being
closed, $1,558,000 million to write-off capitalized direct marketing costs,
$764,000 of prepaid expenses consisting of prepaid license fees, royalties and
trade show costs, $589,000 of customer deductions and concessions and $397,000
in the write-off of purchased intangibles related to product lines for which the
Company announced its plan to cease active pursuit of  new customers and to no
longer provide technical support to existing customers.

The facility and lease loss accrual of $360,000 consists of costs related to the
planned shutdown of the Company's current facility in Morrisville, NC,
including the net book value of remaining leasehold improvements of $115,000.
 
INCOME TAXES.    The provision for income taxes during 1994 consisted of federal
alternative minimum and minimum state taxes.  The tax provision for 1995 was
calculated based upon the Company's effective tax rate, giving benefit to
available net operating loss and credit carryforwards.  In the year ended
December 31, 1996, the Company incurred a significant operating loss. However,
included in the book charges were amounts not currently deductible for income
taxes.  The 1996 tax provision includes the amount currently payable with an
offsetting deferred tax benefit to record a portion of the Company's deferred
tax asset.

   Historically, revenues in the first quarter have been lower than in the
preceding fourth quarter due to customer budgeting and purchasing patterns.  The
Company's results of operations have been and may in the future be subject to
significant quarterly fluctuations.  These fluctuations may be due to a variety
of factors, including the timing of significant orders, the timing of the
introduction or announcement of new or enhanced products by the Company or its
competitors, variations in net revenue by product and distribution channel,
increased price and other competition, capital spending patterns of end-users,
delays in shipping new or existing products, conditions within the software and
networking industries, and economic conditions generally.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has funded its operations to date primarily through cash flow
from operations and private and public placements of capital stock.  At December
31, 1994,  1995, and 1996  the Company had available cash and cash equivalents
of $2.8 million, $33.3 million and $20.8 million, respectively, and working
capital of $1.3 million, $35.6 million and $25.3 million, respectively. On April
1, 1996, the Company acquired a new line of credit with a commercial bank for
$10.0 million  that allows the Company to borrow up to the lesser of $10.0
million or the sum of 80% of qualified domestic accounts receivable and 40% of
qualified foreign accounts receivable.  Borrowings bear interest at the bank's
prime rate.  The line expires April 1, 1998.  Advances pursuant to the line of
credit are secured by liens granted on the Company's accounts receivables. At
December 31, 1994, 1995 and 1996, the Company did not have an outstanding
balance under the line of credit agreement.

     Net cash provided by (used in) operating activities for the years ended
December 31, 1994, 1995 and 1996 was $1.2 million, $(265) thousand and $(656)
thousand, respectively.  In 1994, net cash provided by operating activities
consisted of a $4.1 million net loss which was the result of a $4.7 million
charge for incomplete research and development relating to the acquisition of
DaVinci, a $2.4 million increase in accounts receivable, a $712 thousand
increase in direct marketing costs and a $1.4 million decrease in deferred
revenue offset by an increase of $1.9 million in accounts payable, $1.4 million
in accrued expenses and $1.2 million in the reserve for distributor inventory.
The increase in the reserve for distributor inventory represents the Company's
estimate of product paid for by distributors that will be returned.  In 1995,
net cash used in operating activities consisted of approximately $3.7 million of
net income from operations, a $311 thousand decrease in accrued expenses, a $91
thousand decrease in accounts payable, a $2.0 million increase in accounts
receivable, a $279 thousand decrease in reserve for distributor inventory, and a
$2.0 million increase in inventories.  The increase in inventories was due
primarily to new product introductions, increased stocking levels as a result of
increased revenue and related unit shipments, and procedures put in place by the
Company during 1995 to help ensure more complete availability of product in
stock.   In 1996, net cash used in operating activities consisted of
approximately $15.9 million net loss from operations which was the result of a
$13.3  million charge for incomplete research and development relating to the
acquisitions of Leprechaun Software International, Ltd., neTrend Corporation and
the LAN software business from Technocom, plc, a $3.0 million charge for
restructuring, depreciation and amortization of $3.2 million, offset by an
increase in accounts receivable of $3.2 million and increase in prepaid assets
of $1.4 million.

     Net cash used in investing activities for the years ended December 31,
1994, 1995 and 1996 was $6.1 million, $611 thousand and $9.5 million,
respectively.  This primarily reflects purchases of property and equipment of
$374 thousand, $1.2 million, and $4.5 million, respectively, and direct costs of
the acquisition of DaVinci of $5.0 million in 1994 and of Leprechaun Software
International, Ltd., neTrend Corporation, and the LAN software business from
Technocom plc of $628 thousand, $2.2 million, and $2.0 million, respectively.
While the Company expects capital expenditures to increase as revenue and the
number of employees increases, there are currently no plans to change the
Company's current pattern of investment in property and development on either a
long or short term basis.

     Net cash (used in) provided by financing activities for the years ended
December 31,  1994, 1995 and 1996 was $7.6 million, $31.4 million and ($2.6)
million, respectively.  In 1994, this was the result of multiple private
placements of capital stock of $8.5 million, borrowings under the line of credit
of $562 thousand,   payments under the line of credit of $1.2 million and
principal repayments on obligations of capital leases of $280 thousand.  In
1995, this was a result of principal repayments on obligations of capital leases
of  $869 thousand, and $31.6 million in net proceeds from the issuance of common
stock from the initial public offering in August  1995.  In 1996, this was a
result of principal repayments on obligations of capital leases of $1.2 million
and the purchase of treasury stock of $1.6 million.

  On January 24, 1997, the Company acquired the stock of  Purview Technologies,
Inc. , a development stage company engaged in Internet usage monitoring software
development.  The Company paid $1million in cash and issued 205,712 shares of
its common stock. The aggregate purchase price including estimated direct
acquisition costs was approximately $2.3 million.  This transaction will be
accounted for as a purchase in accordance with APB No. 16.

  On January 28, 1997, the Company acquired the stock of csd Software GmbH , a
German developer and marketer of PC Desktop Software Management Tools.  The
Company paid $5 million in cash and issued 1,315,790 shares of its common stock.
The aggregate purchase price including estimated direct acquisition costs was
approximately $15.6 million.  This transaction will be accounted for as a
purchase in accordance with APB No. 16.

  For each of these acquisitions, the Company is in the process of obtaining
independent appraisals to value the intangible assets acquired including
incomplete purchased research and development.  The Company anticipates that a
substantial portion of the purchase price for these two acquisitions will be
charged to operations as purchased incomplete research and development.

The Company believes that its existing cash balances, funds generated from
operations, and available borrowings under its line of credit will be sufficient
to finance the Company's operations for the next 12 months.  In the event the
Company acquires one
<PAGE>
 
or more businesses or products, the Company's capital requirements could
increase substantially, and there can be no assurance that additional capital
will be available on terms acceptable to the Company, if at all.

To ON Technology Corporation and Subsidiaries:
 
  We have audited the accompanying consolidated balance sheets of ON Technology
Corporation (a Delaware corporation) and subsidiaries as of December 31, 1996
and 1995, and the related consolidated statements of operations, redeemable
convertible preferred stock and stockholders' equity (deficit) and cash flows
for each of the three years in the period ended December 31, 1996.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

  We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

  In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of ON Technology Corporation and
subsidiaries as of December 31, 1996 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1996, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
                                        
(1)  OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

  ON Technology Corporation and its Subsidiaries (the "Company") are engaged in
the development, marketing, sales support, and distribution  of software for
local area networks.
 
  In 1994, the Company acquired all of the outstanding stock of DaVinci Systems
Corporation (DaVinci), a company engaged in the development and marketing of
software. This transaction was accounted for as a purchase in accordance with
Accounting Principles Board (APB) No. 16 (see Note 2).

  During 1996,  the Company completed three acquisitions. The Company acquired
all of the assets and assumed certain liabilities of Leprechaun Software
International, Ltd., certain technology of neTrend Corporation and certain
intangible assets of Technocom plc. These acquisitions were accounted for as the
purchase of business combinations in accordance with APB No. 16 (see Note 3).

  The accompanying consolidated financial statements reflect the application of
certain significant accounting policies as described below and elsewhere in the
notes to the consolidated financial statements.

Principles of Consolidation

  The accompanying consolidated financial statements include the accounts of the
Company and its wholly-owned subsidiaries.  All significant intercompany
transactions and balances have been eliminated in consolidation.

Management 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 revenues and expense during the reporting period.
Actual results could differ from those estimates.

Revenue Recognition

  Revenue from software product sales is recognized upon shipment of the product
to customers where the Company has no significant vendor obligations.  The
Company sells advertising space in its catalog for cash or receives third party
advertised product.  Revenue for catalog advertising space for cash sales is
recognized the day the catalog is mailed to customers.  Revenue for third party
advertised product received is recognized as each item is sold.  The deferred
revenue balance at December 31, 1996 and 1995 relates primarily to revenue on
software maintenance contracts, which is recognized ratably as it is earned.
The reserve for distributor inventories balance at December 31, 1996, 1995 and
1994 relates to sales to distributors for which the Company has accrued its
estimate of future distributor returns when the product was shipped.  In
addition, the Company accrues the costs associated with providing telephone
support related to certain products.

Cash and Cash Equivalents

  The Company follows the provisions of Statement of Financial Accounting
Standards (SFAS) No. 115, Accounting for Certain Investments in Debt and Equity
Securities.  The Company has classified its cash equivalents as held-to-maturity
and recorded them at amortized cost, which approximates market value.  The
Company considers all highly liquid cash investments with maturates of three
months or less at the date of acquisition to be cash equivalents. Cash
equivalents consisted of commercial paper and money market funds at December 31,
1996 and 1995.

Fair Value of Financial Instruments

  SFAS No. 107, Disclosure About Fair Value of Financial Instruments, requires
disclosure of an estimate of the fair value of certain financial instruments.
The Company's financial instruments consist of cash equivalents, accounts
receivable and capital leases.  The estimated fair value of these financial
instruments approximates their carrying value at December 31, 1996 and 1995.
The estimated fair values have been determined through information obtained from
market sources and management estimates.

Direct Marketing Costs

  The Company sells its products through various channels, including free trial
marketing. The Company incurs substantial costs in advance of a free trial
campaign, including the rental of mailing lists, postage and printing. The
Company capitalizes such costs in accordance with the American Institute of
Certified Public Accountants' (AICPA) Statement of Position 93-7, Reporting on
Advertising Costs.  The Company amortizes such costs over a three-month period,
which approximates the period of expected revenues. The Company has recorded
$1,067 and $1,554 of net capitalized direct marketing costs in the accompanying
consolidated balance sheets at December 31, 1996 and 1995, respectively. The
Company recorded $7,387, $7,291 and $3,032 of direct marketing expense for the
years ended December 31, 1996, 1995 and 1994, respectively.

(1)  OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES - (CONTINUED)

The Company accounts for its long-term assets in accordance with SFAS No. 121,
Accounting  for  the Impairment of Long -lived Assets and for Long- lived Assets
to be Disposed of.  Under SFAS No. 121, the Company is required to assess the
valuation of its long-lived assets, including cost in excess of net assets
acquired, based on the estimated future cash flows to be generated by such
assets.  At each balance sheet date, the Company evaluated the realizability of
goodwill based on profitability expectations, using the undiscounted cash flow
method, for each subsidiary having a material goodwill balance.  Based on it's
most recent analysis, the Company believes that no impairment of goodwill exists
at December 31, 1996.

Software Development Costs

  Costs incurred in the development of computer software to be sold have been
expensed as research and development costs in the accompanying consolidated
statements of operations, in accordance with SFAS No. 86,  Accounting  for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed.  SFAS No.
86 requires that costs incurred in creating a computer software product be
charged to research and development expense until technological feasibility has
been established for the product. The costs incurred subsequent to the
attainment of technological feasibility in 1994, 1995 and 1996 are
insignificant. The Company has recorded charges for purchased incomplete
research and development related to the acquisitions discussed in Notes 2 and 3.
In each case, the Company determined that technological feasibility of the in-
process purchased technology acquired had not been established and that the
technology had no alternative future use.

Foreign Currency Translation

  The Company translates the assets and liabilities of its foreign subsidiaries
at the exchange rates in effect at fiscal year-end in accordance with SFAS No.
52, Foreign Currency Translation.  Revenues and expenses are translated using
exchange rates in effect during each period.  The cumulative translation
adjustment component of stockholders' equity relates primarily to the Company's
European operation which was established in 1996.

Postretirement Benefits

The Company has no obligations for postretirement benefits.

Concentration of Credit Risk

  SFAS No. 105, Disclosure of Information about Financial Instruments with Off-
balance-sheet Risk and Financial Instruments with Concentrations of Credit Risk,
requires disclosure of any significant off-balance sheet and credit risk
concentrations. The Company has no significant off-balance-sheet concentrations
of credit risk such as foreign exchange contracts, option contracts or other
foreign hedging arrangements. The Company's financial instruments that  subject
the Company to credit risk consist of cash and cash equivalents and accounts
receivable.  The Company maintains the majority of cash balances with four
financial institutions. The Company's accounts receivable credit risk is not
concentrated within any geographic area, and no single customer accounts for
greater than 10% of revenues or represents a significant credit risk to the
Company.

Pro Forma Net (Loss) Income per Common and Common Equivalent Share

  For the three years ended December 31, 1996, pro forma net (loss) income per
common and common equivalent share was based on the weighted average number of
common and common equivalent shares outstanding during the period, computed in
accordance with the treasury stock method. Pro forma net (loss) income per
common equivalent shares for the years ended December 31, 1995 and 1994 was
computed using the pro forma weighted average number of common shares assuming
that all series of redeemable convertible preferred stock had been converted to
common stock as of the original issuance dates.  Other shares of stock issuable
pursuant to stock options have been included when their effect is dilutive.

Export Revenue

  Export revenue as a percentage of total revenue for the years ended December
31, 1996, 1995 and 1994 was 18%, 14% and 10%, respectively.


(2)  ACQUISITION OF DAVINCI

  On June 1, 1994, the Company acquired all of the outstanding stock of DaVinci.
As consideration, the Company paid $3,532 to DaVinci's shareholders, assumed
$1,479 of liabilities and paid off $900 of DaVinci's notes payable to certain
investors.  This transaction  was accounted for as a purchase, and accordingly,
the results of DaVinci since June 1, 1994, are included in the accompanying
consolidated statements of operations.  The aggregate purchase price of $6,655
(which consisted of $4,432 in cash, including $900 paid to certain investors who
held notes payable, $1,479 of assumed liabilities, and $744 of direct
acquisitions costs) was allocated based on the fair value of the tangible and
intangible assets as follows:

</TABLE>

  Included in purchased intangible assets are amounts related to trade names,
customer lists and acquired technologies including acquired software products.
These intangibles have been fully amortized as of December 31, 1996.  The
portion of the purchase price allocated to incomplete research and development
projects that had not yet reached technological feasibility and did not have a
future alternative use, totaling $4,700, was charged to expense as of the
acquisition date.  The amount allocated to incomplete research and development
projects represents the estimated fair value related to these projects
determined by an independent appraisal.  Proven valuation procedures and
techniques were utilized in determining the fair value of each intangible asset.
To bring these projects to technological feasibility, high risk developmental
and testing issues needed to be resolved which required substantial additional
effort and testing.

(5)  INCOME TAXES

  The Company provides for income taxes in accordance with SFAS No. 109,
Accounting for Income Taxes.  Under the liability method specified by SFAS No.
109, a deferred tax asset or liability is determined based on the difference
between the financial statement and tax basis of assets and liabilities, as
measured by the enacted tax rates assumed to be in effect when these differences
reverse.  The income tax provision for the years ended December 31, 1996 and
1995 was calculated based on the Company's effective tax rate giving benefit to
available net operating loss and research and development credit carryforwards
and by recognizing a portion of the Company's deferred tax asset in the year
ended  December 31, 1996.  The income tax provision for the year ended December
31, 1994 consists of federal alternative minimum and minimum state income taxes
payable.

The components of the provision for income taxes are as follows:

(5)  INCOME TAXES - (CONTINUED)

  The Company has placed a significant valuation allowance against its net
deferred tax asset.  The valuation allowance increased during 1996 by $5,785
since the Company believes it is "more likely than not" that it will not be able
to utilize it's deferred tax asset.  The Company has recorded a deferred tax
asset for that portion to which it will "more likely than not" benefit.

  As of December 31, 1996, the Company has available net operating loss
carryforwards of $1,023.  These carryforwards expire through 2008 and are
subject to review and possible adjustment by the Internal Revenue Service.  The
Tax Reform Act of 1986 contains provisions that may limit the amount of net
operating loss and credit carryforwards that the Company may utilize in any one
year in the event of certain cumulative changes in ownership over a three-year
period in excess of 50%, as defined, therein.

A reconciliation of the federal statutory rate to the Company's effective tax
rate is as follows:

(8)  STOCKHOLDERS' EQUITY

Initial Public Offering

  In August of 1995, the Company completed an initial public offering (the
"IPO") of 2,360,000 shares of its common stock for $15.00 per share.  The sale
of common stock resulted in net proceeds to the company of $31,647, after
deducting all expenses related to the IPO. In connection with the Company's
initial public offering, the redeemable convertible preferred shares were
automatically converted into 3,841,632 shares of common stock.

Common Stock
  The Company has 20,000,000 authorized shares of common stock $.01 par value,
of which 11,008,243 shares were issued and outstanding at December 31, 1996.

Preferred Stock

  The Company has an authorized class of Preferred Stock consisting of 2,000,000
shares, which may be issued from time to time in one or more series.  The
Company's Board of Directors has authority to issue the shares of Preferred
Stock in one or more series, to establish the number of shares to be included in
each series and to fix the designation, powers preferences and rights of the
shares of each series and the qualifications, limitations or restrictions
thereof, without any further vote or action by the stockholders.  The issuance
of Preferred Stock could decrease the amount of earnings and assets available

Plan.

consolidated financial statements for all periods presented to reflect these
split.

Option Plan, as amended (the "Plan").  Pursuant to the Plan, the Company may
grant to employees and consultants of the Company statutory and nonstatutory

  In October 1995, the Financial Accounting Standards Board issued SFAS No. 123
Accounting for Stock Based Compensation, which requires the measurement of the
fair value of stock options or warrants to be included in the statement of
operations or disclosed in the notes to the financial statements.  The Company
has determined that it will continue to account for stock-based compensation for
employees under Accounting Principles Board Opinion No. 25 and elect the
disclosure-only alternative under SFAS No. 123 for options granted in 1996 and
1995 using the Black-Scholes option pricing model  prescribed by SFAS No. 123.
The weighted average assumptions are as follows:

  Had compensation cost for these plans been determined consistent with SFAS No.
123, the Company's net (loss) income and pro forma net (loss) income per share
would have been reduced to the following pro forma amounts:

(9)  STOCK OPTION PLANS-(CONTINUED)

  Because the method prescribed by SFAS No. 123 has not been applied to options
granted prior to January 1, 1995, the resulting pro forma compensation cost may
not be representative of that to be expected in future years.

Employee Stock Purchase Plan

  On May 18, 1995, the Company adopted the 1995 Employee Stock Purchase plan
pursuant to which up to 1,000,000 shares of common stock may be issued.  The
plan consists of semiannual offerings commencing on the first day the Company's
common stock was publicly traded and each subsequent offering commencing on
January 1 and July 1 of each year.  The maximum number of shares of common stock
that may be purchased by an employee is determined on the first day of each
offering period, as defined in the Plan.  The price at which the shares are
purchased is the lower of  85% of the closing price on the first or last day of
the offering period.

(10)   401 (K) PLAN
 
  In 1994, the Company established a plan under Section 401 (k) of the Internal
Revenue Code  (the "401 (k) Plan") covering all eligible employees, as defined.
Participants in the 401 (k) Plan may not contribute more than the lesser of the
specified statutory amount or 15% of his or her pretax total compensation.  The
401 (k) Plan permits, but does not require, additional contributions to the
401(k) Plan by the Company.  The Company made no contributions during 1996,
1995 or 1994.

(11)  ACCRUED EXPENSES

  Accrued expenses consisted of the following:
