                                  JUNE 30, 1997


1.   BASIS OF PRESENTATION

The accompanying consolidated financial statements have been prepared by ISOCOR
(the "Company"), pursuant to the regulations of the U.S. Securities and Exchange
Commission. In the opinion of management, the financial statements include all
adjustments (consisting only of normal recurring adjustments) necessary to
fairly present the consolidated financial position at June 30, 1997, the
consolidated statements of operations for the three and six month periods ended
June 30, 1997 and 1996, and the consolidated statements of cash flows for the
six month periods ended June 30, 1997 and 1996. These interim statements do not
include all of the disclosures required by generally accepted accounting
principles for annual statements.

The statements of operations and cash flows for the 1997 interim periods are not
necessarily indicative of results to be expected for the full year.

These consolidated financial statements should be read in conjunction with the
financial statements included in the Company's Annual Report on Form 10-K, as of
December 31, 1996, as filed with the Securities and Exchange Commission.

CONCENTRATION OF CREDIT RISK

Financial instruments which potentially subject the Company to concentration of
credit risk consist principally of cash, cash equivalents and accounts
receivable. The Company's accounts receivable are derived from sales directly to
customers and indirectly through resellers, systems integrators and OEMs. The
Company performs ongoing credit evaluations of its customers before granting
uncollateralized credit and to date has not experienced any unusual
credit-related losses. Cash equivalents are managed by major investment firms in
accordance with the Company's investment policy. At June 30, 1997, the Company
held balances in U.S. banks of approximately $955,000 which exceeded federally
insured limits.

STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NOT YET ADOPTED

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 128 "Earnings Per Share." This
statement requires dual presentation of newly defined basic and diluted
earnings per share ("EPS") on the face of the income statement for all entities
with complex capital structures. The accounting standard is effective for both
interim and annual periods ending after December 15, 1997 and requires
restatement of all prior period EPS data presented. Earlier application is not
permitted. The Company is currently evaluating the requirements of SFAS No.
128. 

On June 30, 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 130, "Comprehensive Income." This
statement establishes standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial
statements. This accounting standard is effective for fiscal years beginning
after December 15, 1997 and requires restatement of earlier periods presented.
The Company is currently evaluating the requirements of SFAS No. 130.

On June 30, 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 131, "Disclosures about Segments of
an Enterprise and Related Information." This statement establishes standards
for the way that a public enterprise reports information about operating
segments in annual financial statements and requires that those enterprises
report selected information about operating segments in interim financial
reports issued to shareholders. SFAS 131 is effective for fiscal years
beginning after December 15, 1997 and requires restatement of earlier periods
presented. Management is currently evaluating the requirements of SFAS No. 131.

2.   ACQUISITION

Pursuant to the Stock Purchase Agreement dated August 29, 1996 by and among
ISOCOR B.V., a wholly owned subsidiary of the Company, NetCS Informationstechnik
GmbH, a corporation organized under the laws of the Federal Republic of Germany
("NetCS") and the stockholders of NetCS, (the "Purchase Agreement"), the Company
acquired (the "Acquisition") all of the outstanding quota interests (shares) in
NetCS in exchange for an aggregate of 475,000 shares of its Common Stock. NetCS
is a distributor, integrator and developer of communication software products
for the UNIX arena. NetCS has particular expertise in the area of ISDN and
Internet-based communications subsystems including Internet extensions to
wireless messaging systems. As a result of the Acquisition, NetCS has become a
wholly owned subsidiary of ISOCOR B.V. and, in turn, the Company.

The Acquisition has been accounted for under "pooling of interests" accounting
treatment, and therefore, as required by Accounting Principles Board Statement
No. 16, all financial statements herein have been restated as though the
Acquisition had been effected for all periods presented. Therefore, the
Consolidated Statements of Operations in this report include the operations of
NetCS for the three and six months ended June 30, 1996 and 1997 and the
Consolidated Balance Sheets as of December 31, 1996 and June 30, 1997 include
the financial position of NetCS at those respective dates. A reconciliation of
the Company's previously reported revenue and earnings to those earnings shown
in this report is provided below.

7.   PER SHARE INFORMATION

Net income (loss) per common share is computed using the weighted average number
of shares of Common Stock and common equivalent shares outstanding. Common
equivalent shares related to stock options are excluded from the computation
when their effect is antidilutive.

All of the 475,000 common shares of the Company issued to effect the business
combination with NetCS have been treated as outstanding for all periods
presented for the computation of the weighted average number of shares
outstanding as required for "pooling of interests" accounting treatment.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED JUNE 30, 1997 AND 1996

         Revenues. Total revenues were $5,355,000 and $6,467,000 for the three
months ended June 30, 1997 and 1996, respectively, representing a decrease in
1997 of 17% over the same period one year ago. Revenues from domestic sources
accounted for approximately 38% and 21% of total revenues in the three months
ended June 30, 1997 and 1996, respectively, while the Company's international
revenues accounted for 62% and 79%, respectively, of the Company's total
revenues in the same periods.

         Product revenues were $3,796,000 and $5,151,000 for the three months
ended June 30, 1997 and 1996, respectively. The 26% decrease from 1996 to 1997
was mainly due to decreased volumes of, and declining prices for, the Company's
X.400 products, partially offset by increased volumes of the Company's newer
Internet/Intranet products. The decreased volumes of X.400 products sold relate
primarily to a continuing shift in market demand away from the Company's X.400
product lines and the Company expects this market shift to continue.

         Service revenues were $1,559,000 and $1,316,000 for the three months
ended June 30, 1997 and 1996, respectively. The 18% increase from 1996 to 1997
resulted primarily from increased software support and update service fees.

         Cost of Revenues. Cost of product revenues consists primarily of
hardware purchased from third party vendors, costs of media duplication, manuals
and packaging materials, and third party royalties relating to licensed
technology. The decrease in cost of product revenues from the three months ended
June 30, 1996 to the three months ended June 30, 1997 resulted principally from
a decreased level of costs relating to hardware purchased from third party
vendors as a result of decreased sales of these components, a trend which the
Company expects to continue.

         Cost of service revenues consists primarily of personnel-related costs
of providing software support and update, training and installation, and custom
engineering services.

         Gross Profit. Gross profit was $4,135,000 and $5,037,000 for the three
months ended June 30, 1997 and 1996, respectively, representing 77% and 78% of
revenues for those same periods, respectively.



                                       10
   11

         Gross profit from product sales was $3,291,000 and $4,319,000 for the
three months ended June 30, 1997 and 1996, respectively, representing 86.7% and
83.8% of product sales for those same periods, respectively. This percentage
increase is primarily due to the impact of a decreased level of sales which
include hardware components, which carry a higher cost of sale.

         Gross profit from services was $844,000 and $718,000 for the three
months ended June 30, 1997 and 1996, respectively, representing 54.1% and 54.6%
of services revenues for those same periods, respectively.

         Engineering. Engineering expenses were $2,216,000 and $2,253,000 for
the three months ended June 30, 1997 and 1996, respectively, representing 41.4%
and 34.8% of revenues for those same periods, respectively. The absolute
decrease in engineering expenses resulted principally from decreased expenses in
labor and consulting, while the increase in the percentage is primarily driven
by the lower revenue in the three months ended June 30, 1997.

         Sales and Marketing. Sales and marketing expenses were $3,801,000 and
$2,584,000 for the three months ended June 30, 1997 and 1996, respectively,
representing 71.0% and 40.0% of revenues for those same periods, respectively.
The increase in sales and marketing expenses resulted principally from
labor-related costs arising from increased levels of personnel and to a lesser
extent from marketing program expenses. The increased number of personnel and
level of program expenses reflect an intensified focus by the Company on sales
and marketing efforts which the Company expects to continue. The increase
in sales and marketing expenses as a percentage of revenues is also affected by
the lower revenue in the three months ended June 30, 1997.

         Administration. Administration expenses were $749,000 and $649,000 for
the three months ended June 30, 1997 and 1996, respectively, representing 14.0%
and 10.0% of revenues for those same periods, respectively. The absolute
increase primarily resulted from increased labor expenses relating to the
additional personnel devoted to these activities, while the increase in the
percentage is principally driven by the lower revenue in the three months 
ended June 30, 1997.

         Agency Grants. Agency grants have been received from two sources. Under
an incentive program designed to induce organizations to locate and conduct
business in Ireland, the Industrial Development Authority of Ireland makes
grants that are based predominately upon the number of new jobs created by the
Company there. The amount of grants in any given period will therefore vary
based upon the number of jobs created and the timing of receipt of grant aid
payments and will continue to fluctuate on a quarterly basis. The Economic and
Technological Finance Authority - Berlin makes grants to promote research and
development in small and medium-sized German-owned companies located in Berlin.
The grants are paid quarterly based upon actual development costs, including
salaries, and depend upon the work being carried out in Berlin. As of August 31,
1996, the Company is no longer eligible to receive these grants in Germany.

          (Income) loss from currency fluctuations. (Income) loss from currency
fluctuations was $(72,000) and $51,000 for the three months ended June 30, 1997
and 1996, respectively. The fluctuation during these periods resulted from
changes in foreign currency exchange rates.

         Interest income. Interest income was $306,000 for the three months June
30, 1997 as compared with $296,000 in the same period in 1996.





                                       11

         Provision for Income Taxes. The income tax provision of $11,000 on a
pre-tax loss of $2,240,000 for the three months ended June 30, 1997, resulted
from taxes on the Company's international operations. For the three months ended
June 30, 1996, the income tax provision of $93,000 on a pre-tax loss of $94,000
related primarily to the Company's international operations.

RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 1997 AND 1996

         Revenues. Total revenues were $9,189,000 and $12,976,000 for the six
months ended June 30, 1997 and 1996, respectively, representing a decrease in
1997 of 29% over the same period one year ago. Revenues from domestic sources
accounted for approximately 28% and 21% of total revenues in the six months
ended June 30, 1997 and 1996, respectively, while the Company's international
revenues accounted for 72% and 79%, respectively, of the Company's total
revenues in the same periods.

         Product revenues were $6,391,000 and $10,555,000 for the six months
ended June 30, 1997 and 1996, respectively. The 39% decrease from 1996 to 1997
was mainly due to decreased volumes of, and declining prices for, the Company's
X.400 products, partially offset by increased volumes of the Company's newer
Internet/Intranet products. The decreased volumes of X.400 products sold relate
primarily to a continuing shift in market demand away from the Company's X.400
product lines which the Company expects to continue.

         Service revenues were $2,798,000 and $2,421,000 for the six months
ended June 30, 1997 and 1996, respectively. The 16% increase from 1996 to 1997
resulted primarily from increased software support and update service fees.

         Cost of Revenues. Cost of product revenues consists primarily of
hardware purchased from third party vendors, costs of media duplication, manuals
and packaging materials, and third party royalties relating to licensed
technology. The decrease in cost of product revenues from the six months ended
June 30, 1996 to the six months ended June 30, 1997 resulted principally from a
decreased level of costs relating to hardware purchased from third party vendors
as a result of decreased sales of these components, a trend which the Company 
expects to continue.

         Cost of service revenues consists primarily of personnel-related costs
of providing software support and update, training and installation, and custom
engineering services.

         Gross Profit. Gross profit was $6,981,000 and $10,271,000 for the six
months ended June 30, 1997 and 1996, respectively, representing 76% and 79% of
revenues for those same periods.  

         Gross profit from product sales was $5,456,000 and $9,006,000 for the
six months ended June 30, 1997 and 1996, respectively, representing 85.3% of
product sales for each of those same periods, respectively.

         Gross profit from services was $1,513,000 and $1,265,000 for the six
months ended June 30, 1997 and 1996, respectively, representing 54.1% and 52.2%
of services revenues for those same periods, respectively. This percentage
increase is primarily due to reductions in the costs of custom engineering and 
software support and upgrade services.

         Engineering. Engineering expenses were $4,227,000 and $4,371,000 for
the six months ended June 30, 1997 and 1996, respectively, representing 46.0%
and 33.7% of revenues for those same periods, respectively. The absolute
decrease in engineering expenses resulted principally from decreased expenses in
labor and consulting, while the increase in the percentage is driven mainly by 
the lower revenue in the six months ended June 30, 1997.

         Sales and Marketing. Sales and marketing expenses were $7,389,000 and
$4,906,000 for the six months ended June 30, 1997 and 1996, respectively,
representing 80.4% and 37.8% of revenues for those same periods, respectively.
The increase in sales and marketing expenses resulted principally from
labor-related costs arising from increased levels of personnel and to a lesser
extent from marketing program expenses. The increased number of personnel and
level of program expenses reflect an intensified focus by the Company on sales
and marketing efforts which the Company expects to continue. The increase in
sales and marketing expenses as a percentage of revenues is also affected by the
lower revenue in the six months ended June 30, 1997.

         Administration. Administration expenses were $1,567,000 and $1,255,000
for the six months ended June 30, 1997 and 1996, respectively, representing
17.1% and 9.7% of revenues for those same periods, respectively. The absolute
increase primarily resulted from increased labor expenses relating to the
additional personnel devoted to these activities, while the increase in the
percentage is driven principally by the lower revenue in the six months ended 
June 30, 1997.

and 1996, respectively. The fluctuation during these periods resulted from
changes in foreign currency exchange rates.

         Interest income. Interest income was $616,000 for the six months ended
June 30, 1997 as compared with $361,000 in the same period in 1996. The increase
resulted primarily from interest earned on the investment of cash received from
the Company's initial public offering which was completed in mid-March 1996.

         Provision for Income Taxes. The income tax provision was $19,000 on a
pre-tax loss of $5,408,000 for the six months ended June 30, 1997, which
resulted from taxes on the Company's international operations. For the six
months ended June 30, 1996, the income tax provision of $280,000 on pre-tax
income of $291,000 related primarily to the Company's profitable international
operations.

LIQUIDITY AND CAPITAL RESOURCES

During March 1996 the Company completed a public offering and sale of 2,300,000
shares (including the over-allotment option) of its Common Stock at $9 per
share, resulting in net proceeds to the Company after offering costs of
approximately $18,379,000. Concurrently with such offering, the Company received
an additional $1,500,000 from Intel Corporation and an additional $288,000 from
Thomson-CSF Ventures as a result of the sale and issuance of 166,667 and 39,942
shares of Common Stock, respectively.

The Company generated cash from operating activities of $1,544,000 and $605,000
for the six months ended June 30, 1997 and 1996, respectively. The primary
factors contributing to this increase in cash flow in 1997 are increased cash
flow resulting from a net decrease in accounts receivable, offset by a decrease
in cash flow due to the higher operating loss for the six months ended June 30,
1997 of $2.3 million versus an operating loss of $15,000 for the six months
ended June 30, 1996. As of June 30, 1997, total accounts receivable, net was
$8,908,000 versus $11,234,000 at December 31, 1996. This lower accounts
receivable balance at June 30, 1997 is partially attributable to lower revenue
levels in the six months ending at that same date. 

The Company typically generates a large percentage of its quarterly revenue
during the last few weeks of the quarter, and has payment terms in excess of 90
days on some of its larger sales. Certain of the Company's larger sales have
longer payment terms, thus slowing the cash flow cycle, and the Company expects
that future large sales will follow the same pattern. The Company does not
believe these longer payment terms are likely to have a material adverse effect
on the collectibility of the related receivables. 

As of June 30, 1997, the Company had a balance of $12,393,000 in cash and cash
equivalents, and a balance of $10,802,000 in marketable securities. The Company
believes that its existing capital resources will be adequate to finance the
Company's operations and capital expenditures through the end of 1998.
