                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

(1)   Basis of Presentation

      The accompanying unaudited consolidated financial statements have been
prepared by Omtool, Ltd. (the "Company" or "Omtool") pursuant to the rules and
regulations of the Securities and Exchange Commission regarding interim
financial reporting. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements and should be read in conjunction with the consolidated
financial statements and notes thereto for the year ended December 31, 1997. The
accompanying consolidated financial statements reflect all adjustments
(consisting of normal recurring adjustments) which are, in the opinion of
management, necessary for a fair presentation of results for the interim periods
presented. The results of operations for the three month period ended March 31,
1998 are not necessarily indicative of the results to be expected for the full
fiscal year.

(2)   Summary of Significant Accounting Policies

      (a)   Cash and Cash Equivalents

      The Company considers all highly liquid investments with maturities of 
three months or less at the time of purchase to be cash equivalents. Cash 
equivalents consist primarily of investments in money market funds. In 
accordance with Statement of Financial Accounting Standards (SFAS) No. 115, 
Accounting for Investments in Certain Debt and Equity Securities, the 
Company's cash equivalents are classified as held-to-maturity securities.

      (b)   Short-Term Investments

      As of March 31, 1998 and December 31, 1997, the Company had $20,457,149
and $21,179,766, respectively, invested in securities consisting of municipal
bonds. In accordance with SFAS No. 115, the Company has classified its
short-term investments as available-for-sale. These securities have been
recorded at cost, which approximates market value at March 31, 1998 and December
31, 1997.

      (c)   Foreign Currency Translation


      The Company translates the financial statements of its foreign
subsidiaries in accordance with SFAS No. 52, Foreign Currency Translation.
Accordingly, assets and liabilities are translated at exchange rates in effect
at the end of the period, and revenues and expenses are translated at the
average exchange rates during the period. All cumulative translation gains or
losses from the translation into the Company's reporting currency are included
as a separate component of stockholders' equity in the accompanying consolidated
balance sheets.

      (d)   Net Income per Common and Common Equivalent Share

      Effective December 15, 1997, SFAS No. 128, Earnings Per Share, established
standards for computing and presenting earnings per share and applies to
entities with publicly held common stock or potential common stock. The Company
has applied the provisions of SFAS No. 128 retroactively to all periods
presented. In accordance with SEC Staff Accounting Bulletin (SAB) No. 98, the
Company has determined that there were no nominal issuances of common stock or
potential common stock in the period prior to the Company's initial public
offering. The dilutive effect of potential common shares in 1997, consisting of
outstanding stock options and redeemable convertible preferred stock, is
determined using the treasury stock method and the if-converted method,
respectively, in accordance with SFAS 128. Calculations of basic and diluted net
income per common share and potential common share are as follows:

      These transactions were accounted for as pooling of interests. None of 
the periods preceding December 31, 1997 were restated, as net assets and 
liabilities, historic results of operations and cumulative stockholders' 
equity of DPSI and TRS were not deemed to be material to the consolidated 
financial statements of the Company. The Company recorded the costs incurred 
in connection with these transactions as "Acquisition Costs" which are 
included in the accompanying consolidated statements of income.

Item 2.
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

      Management's Discussion and Analysis of Financial Condition and Results of
Operations should be read in conjunction with the accompanying consolidated
financial statements for the periods specified and the associated notes. Further
reference should be made to the Company's Annual Report on Form 10-K as filed
with the Securities Exchange Commission on March 31, 1998.

Overview

      Omtool designs, develops, markets and supports open, client/server
facsimile software, delivering solutions which automate and integrate fax
communication throughout the enterprise. The Company was incorporated in March
1991 and shipped its initial facsimile software products in 1991. The Company's
revenues are primarily derived from licensing the rights to use its Fax Sr. NT
software product directly to end users and indirectly through resellers. The
Company also derives revenues from the resale of third-party hardware products,
principally intelligent fax boards and fax modems, and from the delivery of
related services, consisting primarily of customer support contracts. The
Company first achieved profitability for the year ended December 31, 1992 and
has been profitable, for the last thirteen quarters, excluding a one-time charge
for purchased, in-process research and development in the fourth quarter of
1997.

      The Company has historically derived the majority of its total revenues
from sales within North America. Sales outside of North America represented
approximately 22% and 10% of the Company's total revenues in the three months
ended March 31, 1998 and 1997, respectively.

      The Company sells its products through its direct telesales force and also
sells its products through value added resellers, systems integrators, resellers
and distributors to expand its indirect distribution channel. Sales through the
Company's indirect distribution channels were 27% and 32% of the Company's total
revenues in the three months ended March 31, 1998 and 1997, respectively.

      The Company has expanded its business through three acquisitions. In
December 1997, the Company acquired CMA Ettworth Limited, based in London,
England, a provider of fax solutions for the IBM AS/400 market. The acquisition
was accounted for as a purchase and resulted in a one-time charge for purchased,
in-process research and development of approximately $6.7 million in the fourth
quarter of 1997. In February 1998, the Company acquired Desktop Paging Software,
Inc., a New Hampshire based provider of wireless messaging software, and TRS
Technologies, Inc., a Portland, Oregon based provider of LAN fax and cost
recovery systems for law firms. These acquisitions were accounted for under the
pooling of interest method of accounting.

Three Months Ended March 31, 1998 and 1997

Revenues

      Total Revenues. The Company's revenues are currently derived primarily
from fees from licensing of the Company's software products and, to a lesser
extent, from related sales of hardware and services. The Company's total
revenues were $8.0 million and $3.7 million for the three months ended March 31,
1998 and 1997, respectively, representing an increase of 117%.

      Software License. The Company's software license revenues are derived
primarily from the licensing of the Company's Fax Sr. product. Software license
revenues were $4.8 million for the three months ended March 31, 1998 and $2.5
million for the three months ended March 31, 1997, or 60% and 69% of total
revenues for each respective period, representing an increase of 90%. The
increase in dollar amount was primarily due to increased market acceptance of
the Company's products for various operating systems.


                                       11
<PAGE>

      Hardware. Hardware revenues are derived from the resale of third-party
hardware products sold to the Company's customers in conjunction with the
licensing of the Company's software. Hardware revenues were $1.8 million for the
three months ended March 31, 1998 and $709,000 for the three months ended March
31, 1997, or 22% and 19% of total revenues for each respective period,
representing an increase of 150%. The increase in hardware revenues was due
primarily to the increase of hardware unit sales accompanying the Company's
products and a change in the sales mix of third-party hardware products from
less expensive modem products to high-end multi-channel modem boards.

      Service and Other. Service and other revenues are primarily comprised of
fees from maintenance contracts. Service and other revenues were $1.4 million
for the three months ended March 31, 1998 and $456,000 for the three months
ended March 31, 1997, or 18% and 12% of total revenues for each respective
period, representing an increase of 210%. The increase in dollar amount was due
primarily to the increase in maintenance revenues as a result of a larger
installed customer base.

Cost of Revenues

      Software License. Cost of software license revenues consists primarily of
the costs of sublicensing third-party software products, product media, and
product duplication. Cost of software license revenues was $368,000 and $86,000
for the three months ended March 31, 1998 and 1997, respectively, representing
8% and 3% of software license revenues for each respective period. The increase
in dollar amount was primarily due to the higher volume of products shipped
during the three months ended March 31, 1998 compared to the same period in
1997. Software license gross margin percentages decreased to 92% for the three
months ended March 31, 1998 from 97% for the same period in 1997 due to
increased license fees and royalties paid to third-party software providers.

      Hardware. Cost of hardware revenues consists primarily of the costs of
third-party hardware products. Cost of hardware revenues was $1.0 million and
$494,000 for the three months ended March 31, 1998 and 1997, respectively,
representing 59% and 70% of hardware revenues for each respective period. The
increase in dollar amount for the cost of hardware revenues for the three months
ended March 31, 1998 was due primarily to increased unit sales of hardware
products accompanying licenses of Fax Sr. and a change in the sales mix of
third-party hardware products from less expensive modem products to high-end
multi-channel modem boards. The gross margin percentage for hardware sales
increased to 41% for the three months ended March 31, 1998 from 30% in the same
period in 1997 due to the change in hardware sales mix and better pricing from
third-party hardware vendors.

      Service and Other. Cost of service and other revenues consists primarily
of the costs incurred in providing telephone support as well as other
miscellaneous customer service-related expenses. Cost of service and other
revenue was $818,000 and $229,000 for the three months ended March 31, 1998 and
1997, respectively, representing 58% and 50% of service and other revenues for
each respective period. The increase in dollar amount of cost of service and
other revenues during the period was due primarily the hiring of incremental
personnel to support growth in the customer base. The gross margin percentage
for service and other revenues decreased to 42% from 50% for the three months
ended March 31, 1998 and 1997, respectively, due to the Company's investments in
its infrastructure in anticipation of future expansion of operations.

Operating Expenses

      Sales and Marketing. Sales and marketing expenses consist primarily of
employee salaries, benefits, commissions, and associated overhead costs, and the
cost of marketing programs such as direct mailings, public relations, trade
shows, seminars, and related communication costs. Sales and marketing expenses
were $2.5 million and $1.3 million for the three months ended March 31, 1998 and
1997, respectively, or 32% and 35% of total revenues for each respective period.
The increase in dollar amount was primarily due to the Company's effort to
expand its direct telesales force and marketing organization, higher sales
commissions associated with increased revenues and increased marketing program
activities. The Company expects sales and marketing expenses will continue to
increase in absolute terms.

      Research and Development. Research and development expenses include
expenses associated with the development of new products, enhancements of
existing products and quality assurance activities, and consist primarily of
employee salaries, benefits, and associated overhead costs as well as consulting
expenses and the cost of software development tools. Research and development
expenses were $1.2 million and $764,000 for the three months ended March 31,
1998 and 1997, respectively, or 15% and 21% of total revenues for each
respective period. The increase in dollar amount was primarily attributable to
the 


                                       12
<PAGE>

employment of additional staff and independent contractors to develop and
enhance the Company's products and provide quality assurance. Research and
development expenses decreased as a percentage of total revenues as the Company
continued to realize operating leverage from its established infrastructure. The
Company expects research and development expenses will continue to increase in
absolute terms.

      General and Administrative. General and administrative expenses consist
primarily of employee salaries and benefits for administrative, executive and
financial personnel and associated overhead costs, as well as consulting,
accounting, and legal expenses. General and administrative expenses were
$836,000 and $391,000 for the three months ended March 31, 1998 and 1997,
respectively, or 10% and 11% of total revenues for each respective period. The
increase in dollar amount was primarily attributable to an increase in personnel
and the overhead costs allocated to support such personnel as well as additional
administrative expenses incurred as a result of recent acquisitions. General and
administrative expenses as a percentage of total revenues remained relatively
consistent. The Company expects general and administrative expenses will
continue to increase in absolute terms.

      Acquisition Costs. In connection with the acquisition of Desktop Paging
Software, Inc. and TRS Technologies, Inc., the Company expensed $183,000 of
accounting, legal, and other associated costs. See Note 4 of Notes to
Consolidated Financial Statements.

      Interest Income, Net. Interest income, net consists primarily of interest
earned on cash, cash equivalents, and short-term investments, offset by interest
expense associated with equipment financing and borrowings. Interest income, net
represented income of $189,000 in the three months ended March 31, 1998, due
primarily to interest income earned on excess cash from the proceeds of the
Company's initial public offering completed in August 1997.

      Provision for Income Taxes. Provision for income taxes was $298,000 and
$170,000 for the three months ended March 31, 1998 and 1997, respectively,
resulting in effective tax rates of approximately 25% and 38% in the three
months ended March 31, 1998 and 1997, respectively. Income taxes in 1998 have
been provided at the Company's respective federal and state statutory rates,
reduced primarily for income tax credits and the tax effect of certain
tax-exempt interest income. The effective income tax rate in 1998 is lower than
1997 due primarily to additional tax-exempt interest earned and the change in
federal tax laws extending the research and development credit through June 30,
1998.

Liquidity and Capital Resources

      The Company has financed its operations primarily through cash flow 
from operations, the private sales of preferred stock, and the Company's 
initial public offering of Common Stock completed in August 1997. At March 
31, 1998 the Company had cash and cash equivalents of $2.1 million, 
short-term investments of $20.5 million, and working capital of $24.9 
million. In August 1996, the Company entered into a loan and security 
agreement with a bank which was comprised of a term loan and a line of 
credit. The Company borrowed $250,000 under the term loan, which bore 
interest at the bank's prime rate plus 0.5% and was payable in monthly 
installments through December 31, 1999. In August 1997, the Company 
extinguished the term loan with a portion of the proceeds from the IPO. The 
line of credit expired in August 1997 at which time there were no additional 
amounts outstanding.

      The Company's operating activities used cash of $617,000 in the three
months ended March 31, 1998 and provided cash of $173,000 in the three months
ended March 31, 1997. Net cash used during the three months ended March 31, 1998
consisted primarily of an increase in accounts receivable and a decrease in
income taxes payable offset by increased accounts payable and net income from
operations. Net cash provided during the three months ended March 31, 1997
consisted primarily of net income from operations and an increase in accrued
liabilities offset by an increase in accounts receivable and a decrease in
income taxes payable.

      Investing activities provided cash of $662,000 and used cash of $1.1
million during the three months ended March 31, 1998 and 1997, respectively.
During the three months ended March 31, 1998, the principal uses were purchases
of short-term investments and purchases of property and equipment, offset by the
proceeds from the sale of short-term investments. During the three months ended
March 31, 1997, the principal uses were purchases of property and equipment and
purchases of short-term investments. The Company expects that the rate of
purchases of property and equipment will increase as the Company expands its
operations.

      Financing activities used cash of $167,000 for the three months ended
March 31, 1998 due primarily to the payment of long-term debt. Financing
activities used cash of $14,000 for the three months ended March 31, 1997.

      As of March 31,1998 the Company did not have any material commitments for
capital expenditures.

      Subject to the factors discussed below, the Company believes that the
existing cash balances, short-term investments and cash generated from
operations will be sufficient to finance the Company's operations for the next
twelve months. Although operating activities may provide cash in certain
periods, to the extent the Company grows in the future, its operating and
investing activities may use cash. There can be no assurance that any necessary
additional financing will be available to the Company on commercially reasonable
terms, or at all.

Certain Factors That May Affect Future Results

      Information provided by the Company from time to time including statements
in this Form 10-Q which are not historical facts, are so-called "forward-looking
statements" that involve risks and uncertainties, made pursuant to the safe
harbor provisions of the Private Securities Litigation Reform Act of 1995. In
particular, statements contained in Management's Discussion and Analysis of
Financial Condition and Results of Operations which are not historical facts
(including, but not limited to, statements concerning the plans and objectives
of management; increases in sales and marketing, research and development and
general and administrative expenses; developments relating to the Company's
product and service offerings, markets and acquisitions; anticipated trends in
the Company's business; and the Company's expected liquidity and capital
resources) may constitute 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 include, but are not limited
to, the factors discussed below, and the other risks discussed in the Company's
Annual Report on Form 10-K for the fiscal year ended December 31, 1997 and from
time to time in the Company's other filings with the Securities and Exchange
Commission.

      The Company's future results are subject to substantial risks and
uncertainties. Although the Company has experienced significant percentage
growth in revenue and net income in recent years, the Company does not believe
that prior growth rates are sustainable or indicative of future operating
results. There can be no assurance that the Company will increase its level of
revenues or remain profitable on a quarterly basis or annual basis. In addition,
the Company's limited operating history makes the prediction of future operating
results difficult or impossible. The Company has derived substantially all of
its historical revenues from licenses of Fax Sr. NT and related services and
resale of related hardware. Broad market acceptance of Fax Sr. NT, and the
Windows NT operating system in general, is critical to the Company's future
success. As a result, any decline in demand for or failure to achieve broad
market acceptance of Fax Sr. NT as a result of competition, technological change
or otherwise, would have a material adverse effect on the Company's business,
financial condition and results of operations. The Company's future financial
performance will depend in large part on the successful development,
introduction and customer acceptance of new and enhanced versions of Fax Sr. NT.
There can be no assurance that the Company will continue to be successful in
marketing Fax Sr. NT or any new or enhanced versions of Fax Sr. NT.

      The enterprise, client/server facsimile solution market is intensely
competitive and rapidly changing and the Company expects competition to continue
to increase. Many of the Company's competitors have longer operating histories
and greater financial, technical, sales, marketing and other resources, as well
as greater name recognition and market acceptance of their products and
technologies than the Company. In addition, there are relatively low barriers to
entry in the markets in which the Company operates, and new competition may
arise either from expansion by established companies or from new emerging
companies or from resellers of the Company's products. There can be no assurance
that current or potential competitors of the Company will not develop products
comparable or superior in terms of price and performance features to those
developed by the Company, adapt more quickly than the Company to new or emerging
technologies and changes in market opportunities or customer requirements,
establish alliances with industry leaders, or take advantage of acquisition
opportunities more readily than the Company. Increased competition will result
in decreased market share, pressure for price reductions and related reductions
in gross margins, any of which could materially adversely affect the Company's
ability to achieve its financial and business goals.

      The Company's future earnings and stock price may be subject to
significant volatility, particularly on a quarterly basis. The Company's
quarterly revenues and results of operations have fluctuated significantly in
the past and will likely fluctuate significantly in the future. Causes of such
fluctuations have included and may include, among others, the demand for the
Company's products and services, the size and timing of orders, the number,
timing and significance of new product announcements by the Company and its
competitors, the ability of the Company to develop, introduce, market and ship
new and enhanced versions of the Company's products on a timely basis, the level
of product and price competition, changes in operating expenses, changes in
average selling prices and mix of the Company's products, changes in the
Company's sales incentive strategy, the mix of direct and indirect sales, and
general economic factors. The Company's products often have a lengthy sales
cycle, especially in the case of large orders. If one or more large orders fails
to close as forecasted by the Company in a fiscal quarter, the Company's
revenues and operating results for such quarter could be materially adversely
affected. Any one or more of these or other factors could have a material
adverse effect on the Company's business, financial condition and results of

                                       15

operations. Any shortfall in revenue or earnings from levels anticipated by 
securities analysts could have an immediate and material adverse effect on 
the trading price of the Company's common stock. The Company typically 
receives and fulfills a majority of its orders within any given quarter, with 
a substantial portion occurring in the last weeks or days of the fiscal 
quarter. As a result, the Company may not learn of revenue shortfalls until 
late in a fiscal quarter, which could result in an even more immediate and 
adverse effect on the trading price of the Company's common stock.

      In addition, the Company identifies the following risk factors which could
affect the Company's actual results and could cause actual results to differ
materially from forward-looking statements. The Company's future results remain
difficult to predict and may be affected by a number of factors, including: the
Company's dependence on the continued acceptance and growth of the Windows NT
environment and of the client/server environment; the ability of the Company to
manage growth; the ability of the Company to enhance existing products and
introduce new products in a timely manner and market acceptance of these
products; the expansion of indirect sales channels and the potential for channel
conflict; risks associated with acquisitions; risks associated with
international expansion; risks associated with the development and maintenance
of strategic relationships; the Company's dependence on revenues from resale of
third-party hardware products; the risks associated with new product offerings
and the potential for undetected errors; the Company's dependence on proprietary
technology and the risk of third-party claims for infringement of intellectual
property rights; and the Company's dependence on third-party licensed
technology; and the Company's dependence on key personnel.
