                               TEXT OF AMENDMENTS


Each of the above listed Items is hereby amended by deleting the Item in its
entirety and replacing it with the respective Item included hereinafter and
filed herewith.

Subsequent to the filing of Omega Research, Inc.'s Consolidated Financial
Statements for each of the three years ended December 31, 1999 on Form 10-K and
in connection with its review of a registration statement on Form S-4 related to
the proposed merger with onlinetradinginc.com corp. ("OnlineTrading.com") (see
Note 15 of Notes to Consolidated Financial Statements elsewhere in this report),
the Staff of the Securities and Exchange Commission ("SEC") expressed concern
about the method of accounting for revenue recognition of licensing fees used by
Omega Research, Inc. (the "Registrant" or the "Company") and its method of
accounting for the acquisition of Window On WallStreet Inc. ("Window On
WallStreet"). As a result of consultation with the Staff of the SEC, the Company
restated certain of its annual and quarterly financial statements as discussed
below.

As a result of the restatement, (i) beginning in 1999, revenues with respect to
the Company's sales of its 2000i products are recognized on an as due basis in
accordance with the payment terms of the sales; and (ii) the Company's October
1999 merger with Window On WallStreet was accounted for under the purchase
method of accounting.

Accordingly, the purpose of this amendment is to restate the Company's
historical consolidated financial statements to reflect these changes. The
Company is amending and restating only those items of its Form 10-K that are
affected by the restatement adjustments listed above. The Form 10-K still speaks
as of December 31, 1999 (except as otherwise expressly noted therein or herein),
and the items herein have been modified or updated as required to reflect the
effects of the restatement adjustments to the consolidated financial statements.


                                       1
<PAGE>

The restatement, as it relates to revenue recognition, relates solely to the
timing thereof and has no impact on cash flow. The primary effect of this change
is to shift a portion of the 1999 and early 2000 net revenues and operating
income to 2000 and, to a lesser extent, to 2001. This shift in timing of revenue
recognition does not change the Company's expectations that its change in
business model will result in net losses at least through the first quarter of
2001. The revenue recognition timing changes do not impact revenue recognition
for the Company's Internet subscription services or other revenues, or any of
the Company's planned service offerings, which are expected to generate the
majority of the Company's revenues in the future. The amounts reported for 1997
and 1998 are the same as the Company had previously reported prior to the Window
On WallStreet acquisition in its Annual Report on Form 10-K for the year ended
December 31, 1998 filed with the SEC on March 30, 1999. See Note 2 of Notes to
Consolidated Financial Statements elsewhere in this report.

(1)  The selected financial data as of and for the year ended December 31, 1999
     has been restated. The amounts above for 1995 through 1998 are the same as
     the Company had previously reported prior to the Window On WallStreet
     acquisition since the Company is accounting for that transaction under the
     purchase method of accounting and not under the pooling-of-interest method
     of accounting. See Note 2 of Notes to Consolidated Financial Statements.

(2)  Prior to 1999, licensing fees were recognized in full (net of provision for
     anticipated returns) upon shipment. Upon the release of the Company's 2000i
     product line, the Company began recognizing sales on an as due basis in
     accordance with the payment terms of the sale (generally over a period of
     up to 12 to 16 months). See Note 1 of Notes to Consolidated Financial
     Statements.

(3)  The Company was treated as an S corporation for federal and state income
     tax purposes prior to September 30, 1997. Pro forma income taxes have been
     provided as if the Company had been a C corporation for all periods prior
     to September 30, 1997. Upon terminating its S corporation election, the
     Company was required to record a non-recurring credit. See Note 9 of Notes
     to Consolidated Financial Statements.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

This discussion should be read in conjunction with Selected Financial Data and
the Consolidated Financial Statements and Notes to Consolidated Financial
Statements contained in this report.

Overview

         Omega Research was incorporated in 1982 to develop, market and sell
trading strategy software tools to traders. The Company's current products and
services provide traders with the ability to develop, historically test and
computer automate trading strategies and to access streaming real-time charts,
quotes and news via the Internet.

         The Company is in the process of changing its business model. The
Company has taken steps to transform itself from a trading strategy client
software company to an on-line brokerage firm that intends to provide to active
traders a best-of-breed, Internet-based trading platform: One that incorporates
and seamlessly integrates powerful trading strategy development tools,
historical and streaming real-time market data and news, and a direct access
electronic order execution system. The Company's historical business model has
consisted of sales of client software products, payment for which is committed
to in full by the customer at the time of sale. Under the new business model,
the Company will seek to derive recurring revenues from customers by offering
monthly subscription services for trading strategy development tools integrated
with streaming real-time market data and news for which a monthly fee is
payable, and by offering on-line brokerage services for which commissions are
payable. The Company


                                       4
<PAGE>

believes that it will be able to leverage its historical success in selling
trading strategy tools to build a subscriber base of active traders that will
use its on-line brokerage services or, at a minimum, its trading strategy
subscription services.

         To support the change in the business model, the Company expects to
increase significantly its sales and marketing, product development and
infrastructure expenditures. As a result, the Company expects to incur net
losses at least through the first quarter of 2001. These anticipated losses
could reduce the Company's available cash resources, increase its capital
requirements and require the Company to seek debt and/or equity financing. See
"Liquidity and Capital Resources" below.

         On February 22, 1999, the Company released its latest generation of
premium software products, branded "2000i," which included upgrade versions of
its then existing products and new products. Accordingly, as of February 22,
1999, the Company's client software product line consisted of TradeStation
2000i, RadarScreen 2000i, OptionStation 2000i, Omega Research ProSuite 2000i and
SuperCharts 4. See "ITEM 1. BUSINESS - Overview and Recent Developments" and -
"Products and Services."

         Through 1999, substantially all of the Company's licensing fees were
derived from the licensing of client software products to individual traders.
The Company's client software products are sold primarily by the Company's
telesales force. To date, a majority of the licensing fees have been generated
through sales of TradeStation and the Omega Research ProSuite (see Note 13 of
Notes to Consolidated Financial Statements). For sales of most of the Company's
client software products, customers have typically provided the Company with a
credit card number and were billed for their purchases automatically and on a
monthly basis over the course of up to 12 months and, for Omega Research
ProSuite 2000i sales, over the course of up to 16 months. The concentration of
the Company's marketing efforts will migrate towards its subscription services
during 2000. Furthermore, as a result of the Company's transition from a seller
of client software to a provider of Internet subscription services, it is
expected that net revenues will be adversely impacted. Revenues from licensing
fees are expected to decrease quarter over quarter in 2000 and it is difficult
to predict when, if at all, or to what extent, revenues from the Company's
Internet subscription services will offset such reductions.

         Historically, the Company's revenues have been derived principally from
two sources: (i) licensing fees for use of the Company's client software
products, and (ii) other revenues consisting primarily of royalties, fees and
commissions paid to the Company in accordance with its agreements with
third-party data vendors and other third parties and, beginning in October 1999,
revenue from the Company's Financial Data Cast Network ("FDCN") subscription
service. Prior to February 1999, licensing fees were recognized upon product
shipment in accordance with Statement of Position ("SOP") 97-2, Software Revenue
Recognition and an estimate for returns was provided in accordance with
Statement of Financial Accounting Standards ("SFAS") No. 48, Revenue Recognition
When Right of Return Exists. Beginning in 1999 with the launch of the Company's
2000i product line, changes in the Company's client software product sales,
including introduction of a new, higher-priced product and longer financing
terms, were deemed to alter the predictability of return reserves and the future
collectibility of receivables. Accordingly, all 2000i product sales are
recognized as they become due (generally over the 12 to 16 month financing terms
for these sales, as monthly payments are due). The revenue recognition changes
relate solely to the timing of revenue recognition with


                                       5
<PAGE>

respect to sales of 2000i products and have no impact on cash flow. The 2000i
products are legacy products of the Company. These revenue recognition timing
changes do not impact revenue recognition for the Company's Internet
subscription services or other revenues, or any of the Company's planned service
offerings, which are expected to generate the majority of the Company's revenues
in the future. See Note 1 of Notes to Consolidated Financial Statements.

         The Company provides client software customers with a 30-day right of
return and, prior to 1999, recorded a provision for estimated returns at the
time of sale. To maintain a positive, customer-friendly environment, the Company
has historically accepted returns in excess of 30 days. Approximately, 90% of
all returns accepted under the 30-day right of return policy are initiated
within 60 days following the date of sale. The reserve for returns and the
provision for bad debts, in accordance with SFAS No. 48, were estimated based on
historical experience and other relevant factors. Actual returns processed were
$7.4 million, $22.1 million and $13.4 million in 1999, 1998 and 1997,
respectively. The decrease in actual returns in 1999 was due to the change in
the recognition of 2000i licensing fee revenue to an as due basis. The increase
in actual returns processed in 1998 when compared to 1997 occurred on a gradual
basis from the beginning to the end of 1998. Management believes this increase
relates to an expanded marketing and sales effort which included television
advertising, and an increasing public awareness of trading, which resulted in
the Company reaching a broader audience that included more individuals who may
not have necessarily been suited to use the Company's products. The Company
maintained an allowance for returns of approximately $83,000, $7.4 million and
$4.2 million at December 31, 1999, 1998 and 1997, respectively. Actual returns
processed during 1999 (for sales made on or prior to December 31, 1998) and 1998
(for sales made on or prior to December 31, 1997) were approximately $7.4
million and $4.3 million, respectively. Additionally, the Company maintained an
allowance for bad debts of $716,000, $3.7 million and $3.2 million as of
December 31, 1999, 1998 and 1997, respectively. Provision for bad debts was
$25,000, $2.2 million and $2.5 million in 1999, 1998 and 1997, respectively. The
decrease in bad debts during 1999 was due to the change in the recognition of
2000i licensing fees to an as due basis. The Company wrote off $3.0 million,
$1.7 million and $52,000 in delinquent accounts in 1999, 1998, and 1997,
respectively.

         While the Company has no obligation to perform future services
subsequent to shipment of client software, for a limited time, the Company
voluntarily provides support on its web site, periodic "bug" fixes, and
telephone and electronic mail customer support as an accommodation to purchasers
of its products as a means of fostering customer satisfaction. The majority of
such services are provided during the first 60 days of ownership of the
Company's products. The costs associated with these services are insignificant
in relation to product sales value and are accrued at the date the software is
delivered. As of December 31, 1999, 1998 and 1997, the Company had accrued
$161,000, $174,000 and $166,000, respectively.

         The Company began to implement the change in its business model with
its October 1999 acquisition of Window On WallStreet, a provider of
Internet-based streaming real-time market data through its FDCN subscription
service. The Consolidated Financial Statements contained herein reflect the
transaction under the purchase method of accounting. In November 1999, the
Company announced that it would focus on serving active on-line traders by
offering a new monthly subscription, Internet-based trading strategy portal that
is to be named TradeStation.com. TradeStation.com is expected to be launched by
the end of 2000. On January 19, 2000, the Company signed a definitive, 100%
share-exchange merger agreement with


                                       6
<PAGE>

OnlineTrading.com, a direct access on-line broker. That merger is expected to be
accounted for as a pooling-of-interests. OnlineTrading.com provides electronic
order execution technology that directly accesses ECN's, exchanges and market
makers in order to provide OnlineTrading.com's customers with high-speed and
efficient order execution that avoids traditional market maker participation and
brokerage order-flow arrangements. The Company launched its first Internet
subscription service, WindowOnWallStreet.com, on January 25, 2000.
WindowOnWallStreet.com offers streaming real-time charts, quotes and news,
powered by certain of the Company's award-winning trading tools. See "ITEM 1.
BUSINESS - Overview and Recent Developments" and - "Products and Services."

         The majority of the Company's other revenues for the year ended
December 31, 1999 were derived from royalties associated with a licensing
agreement with Bridge Telerate relating to TradeStation. Under that agreement,
Bridge Telerate has the right to offer TradeStation to its customers on a
subscription basis. Bridge Telerate pays a per unit royalty to the Company,
subject to a minimum annual royalty commitment. The remaining other revenues has
been comprised of fees and commissions paid to the Company pursuant to
cross-marketing agreements with data service vendors and other third parties,
revenues from the FDCN subscription service and revenues generated from
OmegaWorld, the Company's annual conference for users of Omega Research
products. The Company's decision to focus its marketing resources on
WindowOnWallStreet.com and future Internet subscription services is expected to
result in reduced commission revenue from data service vendors. However, it is
difficult to predict when, if at all, or to what extent, revenues from the
Company's Internet subscription services will offset such reductions. Other
revenues are recognized as earned in accordance with the terms of the applicable
contract; Internet subscription services are recognized monthly as service is
provided; and, with respect to OmegaWorld, at the time the conference is
conducted.

         In accordance with SFAS No. 86, Accounting for the Cost of Capitalized
Software to be Sold, Leased or Otherwise Marketed, the Company examines its
software development costs after technological feasibility has been established
to determine the amount of capitalization that is required. Based on the
Company's product development process, technological feasibility is established
upon completion of a working model. The costs that are capitalized are amortized
on the straight-line basis over a one-year period, the period of benefit of the
related products. There were no capitalized software development costs as of
December 31, 1999 or 1998. In the future, the Company believes that the time
between the technological feasibility of the Company's Internet-based services
and the general release of such services will be insignificant, and, as a
result, development costs qualifying for capitalization are expected to be
immaterial.

         In 1988, the Company elected to be taxed under Subchapter S of the
Internal Revenue Code of 1986, as amended (the "Code"), and, as a result, the
Company's earnings prior to September 30, 1997 (the effective date of the
Company's initial public offering) were taxed at the federal level directly to
the Company's shareholders (the State of Florida does not have a personal income
tax). Effective September 30, 1997, the Company terminated its S corporation
election and became subject to corporate-level federal and state income taxes.
As a result of terminating this election, the Company was required to record a
non-recurring credit (the "SFAS No. 109 Credit"). The SFAS No. 109 Credit
represents the recognition of net deferred tax assets arising from the book and
tax basis differences that arise primarily as a result of accounts receivable
reserves. The SFAS No. 109 Credit, net of a $1.8 million provision for income
taxes payable, was approximately $1.2 million as of September 30, 1997, the date
the S corporation election was terminated. See "Income Taxes" below.

         The pro forma income tax adjustments for the year ended December 31,
1997 in the Company's historical financial statements reflect the federal and
state income taxes which would have been recorded if the Company had been
treated as a C corporation during the periods presented. The Company has
calculated these amounts based upon an estimated combined effective tax rate of
39.5% for Omega Research (as a stand-alone company, prior to its merger with
Window On WallStreet) for the period prior to September 30, 1997. In addition,
the non-recurring net tax credit of $1.2 million has been excluded from pro
forma net income.

Results of Operations

     The results of operations for the three years ended December 31, 1999 have
been restated. The amounts below for 1997 through 1998 are the same as the
Company had previously reported prior to the Window On WallStreet acquisition in
its Annual Report on Form 10-K for the year ended December 31, 1998 (filed with
the SEC on March 30, 1999) since the Company is accounting for that transaction
under the purchase method of accounting. See Note 2 of Notes to Consolidated
Financial Statements. The following table presents, for the periods indicated,
certain items in the Company's consolidated statement of operations reflected as
a percentage of total net revenues:

Years Ended December 31, 1999 and 1998

Net Revenues

         Total Net Revenues. The Company's total net revenues decreased 16% from
$28.2 million in 1998 to $23.7 million in 1999.


                                       8
<PAGE>

         Licensing Fees. Licensing fees decreased 26% from $22.0 million in 1998
to $16.2 million in 1999, primarily due to a change in the method for
recognizing revenue on sales of the Company's 2000i products in 1999. Prior to
1999, licensing fees were recognized in full (net of provision for anticipated
returns) upon shipment. Upon the release of the Company's 2000i product line at
the beginning of 1999, the Company began recognizing sales on an as due basis in
accordance with the payment terms of the sale (generally over a period of up to
12 to 16 months) as changes in the Company's product sales, including
introduction of a new, higher-priced product and longer financing terms, were
deemed to alter the predictability of return reserves and the future
collectibility of receivables. As a result of the Company's focus on building
its Internet subscriber base, it is expected that licensing fees will decrease
quarter over quarter as the balance of the 1999 product sales are recognized and
the number of new licensing fee transactions decrease. It is difficult to
predict when, if at all, or to what extent, revenues from the Company's Internet
subscription services will offset such reductions in licensing fees.

         Other Revenues. Other revenues increased 21% from $6.2 million in 1998
to $7.5 million in 1999, primarily due to an increase in minimum royalties of
$1.0 million under the Company's license agreement with Bridge Telerate,
revenues generated from OmegaWorld, the Company's annual conference for users of
Omega Research products, and the addition of two months of revenues from FDCN,
the Company's real-time market data subscription service acquired in the October
1999 acquisition of Window on WallStreet.

Operating Expenses

         Cost of Licensing Fees. Cost of licensing fees consisted primarily of
costs related to data redistribution, product media, packaging and storage and
inventory costs. Cost of licensing fees was approximately $1.9 million in 1999
as compared to $1.8 million in 1998. Cost of licensing fees as a percentage of
licensing fee revenue increased from 8% in 1998 to 12% in 1999, primarily due to
the 1999 shift in recognition of revenue to an as due basis in accordance with
the payment terms of the sale, partially offset by the impact of a one-time
payment made to a third party in conjunction with the development of certain
technology for the Company during 1998.

         Product Development. Product development expenses included expenses
associated with the development of new products and services, enhancements to
existing products and services, testing of products and services and the
creation of documentation, and consisted primarily of salaries, other personnel
costs and depreciation of computer and related equipment. Product development
expenses increased from $3.3 million in 1998 to $4.7 million in 1999 primarily
due to increased personnel and related costs of $1.2 million due to an increase
in the number of individuals employed in product development from 45 at December
31, 1998 to 72 at December 31, 1999 (inclusive of 13 product development
employees from Window On WallStreet). Product development expenses as a
percentage of total net revenues increased from 12% in 1998 to 20% in 1999
primarily due to an increase in personnel and related costs and the change in
1999 revenue recognition of 2000i licensing fees to an as due basis. The Company
anticipates that the absolute dollar amount of product development expense will
increase for the foreseeable future as the Company develops new products and
services in connection with its new business model and enhances existing
products and services.


                                       9
<PAGE>

         Sales and Marketing. Sales and marketing expenses have consisted
primarily of marketing programs, including advertising, brochures, direct mail
programs and seminars to promote the Company's client software products to
investors, sales commissions, salaries for the customer support center and
marketing personnel, other personnel costs, web site maintenance and
administration costs, and shipping expenses. Sales and marketing expenses were
$18.2 million in 1999 compared to $14.4 million in 1998, primarily due to
increased personnel and related costs of $2.8 million due to a 60% increase in
marketing and sales personnel from 108 at December 31, 1998 to 173 at December
31, 1999 (inclusive of 16 sales and marketing employees from Window On
WallStreet), increased travel expenses and increased costs related to
OmegaWorld. Sales and marketing expenses as a percentage of total net revenues
increased from 51% in 1998 to 77% in 1999 primarily due to the change in 1999
revenue recognition of 2000i licensing fees to an as due basis.

         General and Administrative. General and administrative expenses consist
primarily of employee-related costs for administrative personnel such as
executive, human resources, finance and information technology employees,
professional fees, rent, provision for bad debts (1998 only) and other
facilities expense. General and administrative expenses were $4.5 million in
1999 compared to $6.1 million in 1998 primarily as a result of a decrease in bad
debt expense of $2.2 million related to the 1999 shift in licensing fee revenue
recognition to an as due basis, and decreased consulting and professional
expenses of $528,000 mainly as a result of the favorable settlement of the class
action law suit brought against the Company in 1998, partially offset by an
increase in personnel and related costs and facility expenses. General and
administrative expenses as a percentage of total net revenues improved from 22%
in 1998 to 19% in 1999, primarily as a result of a decrease in bad debt expense
partially offset by the change in 2000i licensing fee revenue recognition to an
as due basis. The Company believes that the absolute dollar amount of its
general and administrative expenses in the future will depend, to a large
extent, on the level of hiring of additional personnel to support the expected
growth of the Company and the Company's change in its business model.

         Amortization of Goodwill and Other Intangible Assets. The October 26,
1999 acquisition of Window on WallStreet was accounted for under the purchase
method of accounting. The excess purchase price paid (including acquisition
costs of $1.2 million) over the net book value of assets was allocated to
goodwill and other identifiable intangible assets (the value of which was
determined by an independent appraisal). Other intangible assets consist of
purchased technology and workforce, trademarks, patents, customer lists and
non-compete agreements with useful lives ranging from three to four years. In
1999, amortization of goodwill and other intangible assets was approximately
$68,000 and $824,000, respectively.

Other Income, Net

   Other income, net consists primarily of investment income from cash and cash
equivalents and marketable securities. The Company generally invests in
overnight investments, tax exempt commercial paper and investment grade
short-term municipal bonds. The amount of interest income fluctuates based on
the amount of funds available for investment and the prevailing interest rates.
Other income, net was approximately $422,000 in 1999 and $424,000 in 1998.

Years Ended December 31, 1998 and 1997

Net Revenues

         Total Net Revenues. The Company's total net revenues were $28.2 million
in 1998 compared to $29.2 million in 1997.

         Licensing Fees. Licensing fees were $22.0 million in 1998 as compared
to $24.4 million in 1997, primarily due to a decrease in net sales of all of the
Company's principal products. The Company believes that licensing fees in 1998
were impacted by slower than anticipated demand for its products, which was
first experienced during the fourth quarter of 1997. Management believes that
the slower demand was due in part to customer delays in decision making in
anticipation of the release of the Company's 2000i software products, which were
released on February 22, 1999.

         Other Revenues. Other revenues increased 28% from $4.9 million in 1997
to $6.2 million in 1998, primarily due to an increase in minimum royalties under
the Company's license agreement with Bridge Telerate, and, to a lesser extent,
revenues generated from OmegaWorld, the Company's annual conference for users of
Omega Research products.

Operating Expenses

         Cost of Licensing Fees. Cost of licensing fees was approximately $1.8
million in both 1998 and 1997. Cost of licensing fees as a percentage of
licensing fees increased slightly in 1998, primarily due to a one-time payment
made to a third party in conjunction with the development of certain technology
for the Company.

         Product Development. Product development expenses increased from $1.9
million in 1997 to $3.3 million in 1998 primarily due to increased personnel and
related costs of $1.3 million due to a 55% increase in the number of individuals
employed in product development from 29 at December 31, 1997 to 45 at December
31, 1998. Product development expenses as a percentage of net revenues increased
from 7% in 1997 to 12% in 1998, primarily due to increased personnel and related
expenses as well as decreased licensing fees.

         Sales and Marketing. Sales and marketing expenses were $14.4 million in
1998 compared to $11.3 million in 1997, primarily due to increased personnel and
related costs of $1.4 million due to a 21% increase in marketing and sales
personnel from 89 at December 31, 1997 to 108 at December 31, 1998, increased
advertising and promotional expenses (including print advertising, the use of
sales seminars, television advertising and direct mailers) of $1.1 million, and
to a lesser extent increased shipping costs and costs related to OmegaWorld,
partially offset by decreased communications expenses. Sales and marketing
expenses as a percentage of net revenues increased from 39% in 1997 to 51% in
1998 as a result of the increased marketing expenses discussed above and
decreased licensing fees.

         General and Administrative. General and administrative expenses were
$6.1 million in 1998 compared to $5.4 million in 1997 primarily as a result of
increased professional fees related to the defense of the class action lawsuit
brought against the Company in 1998, costs of being a


                                       11
<PAGE>

public company and expenses related to the implementation and lease of a new
telephone system, partially offset by a decrease in bad debt expense. General
and administrative expenses as a percentage of net revenues increased from 19%
in 1997 to 22% in 1998 primarily as a result of the increase in those expenses
and decrease in net licensing fees.

Other Income, Net

         Other income, net increased from approximately $146,000 in 1997 to
$424,000 in 1998, primarily due to income earned on the proceeds from the
Company's initial public offering.

Income Taxes

         For income tax purposes, the Company was an S corporation prior to
September 30, 1997. Accordingly, net income and related timing differences which
arose in the recording of income and expense items for financial reporting and
tax reporting purposes were included in the individual tax returns of the S
corporation shareholders. Effective September 30, 1997, the Company terminated
its S corporation election, and, as a result, adopted SFAS No. 109, Accounting
for Income Taxes. SFAS No. 109 requires that deferred income tax balances be
recognized based on the differences between the financial statement and income
tax bases of assets and liabilities using the enacted tax rates.

         Upon adoption of SFAS No. 109 during the third quarter of 1997, the
Company recorded a benefit for income taxes which reflects the SFAS No. 109
Credit, a non-recurring deferred income tax credit of approximately $3.0
million, which was partially offset by a $1.8 million provision for income taxes
payable. The SFAS No. 109 Credit recognized net deferred tax assets arising from
book and tax basis differences that arose primarily as a result of accounts
receivable reserves. The $1.8 million in income taxes payable relate to federal
and state income taxes owed by the Company as a result of an approximate $4.6
million in S corporation taxable earnings which were recognized by the Company
for tax purposes in the fourth quarter of 1997 and the year ended December 31,
1998.

         The pro forma income tax adjustments for the year ended December 31,
1997 in the Company's historical financial statements reflect the federal and
state income taxes which would have been recorded if the Company had been
treated as a C corporation during the periods presented. The Company calculated
those amounts based upon an estimated combined effective tax rate of 39.5% for
Omega Research for periods prior to September 30, 1997.

         The effective tax rate for 1999 approximated the 38.6% statutory rate.
The effective tax rate for 1998 was 35%, below the 38.6% statutory rate
primarily as a result of the impact of tax-free investment income.

Variability of Results

         The operating results for any quarter are not necessarily indicative of
results for any future period or for the full year. The Company's quarterly
revenues and operating results have varied in the past, and are likely to vary
even further from quarter to quarter in the future due to the Company's
transition to a new business model. Such fluctuations may result in volatility
in the price of the Common Stock. As budgeted expenses are based upon expected
revenues, if actual revenues on a quarterly basis are below management's
expectations, then results of


                                       12
<PAGE>

operations are likely to be adversely affected because a relatively small amount
of the Company's expenses varies with its revenues in the short term. In
addition, operating results may fluctuate based upon the timing, level and rate
of acceptance of releases of new products and services and/or enhancements,
increased competition, variations in the revenue mix, and announcements of new
products and services and/or enhancements by the Company or its competitors and
other factors. Such fluctuations may result in volatility in the price of the
Common Stock. See Note 14 of Notes to Consolidated Financial Statements for
quarterly financial information.

Liquidity and Capital Resources

         As of December 31, 1999, the Company anticipated that its available
cash resources and cash flows from operations would be sufficient to meet its
presently anticipated working capital and capital expenditure requirements
through the year 2000. However, the Company is experiencing a period of net
losses which is expected to continue at least through the first quarter of 2001.
Further, as the Company transitions to its new business model, it may need to
raise additional funds in order to execute that transition, support more rapid
expansion, develop new or enhanced services and products, respond to competitive
pressures, and acquire complementary businesses or technologies and/or take
advantage of unanticipated opportunities. The Company has also recently
substantially increased its rental obligations under real property, facilities
and equipment leases. The Company's future liquidity and capital requirements
will depend upon numerous factors, including the period of time it takes the
Company to execute its transition to its new business model, and customer
acceptance thereof, costs and timing of expansion of research and development
and marketing efforts and the success of such efforts, the success of the
Company's existing and new product and service offerings, and competing
technological and market developments. The Company's forecast of the period of
time through which its financial resources will be adequate to support its
operations involves risks and uncertainties, and actual results could vary. The
factors described earlier in this paragraph, as well as other factors, will
impact the Company's future capital requirements and the adequacy of its
available funds. If additional funds are raised through the issuance of equity
securities, the percentage ownership of the shareholders of the Company will be
reduced, shareholders may experience additional dilution in net book value per
share or such equity securities may have rights, preferences or privileges
senior to those of the holders of the Company's common stock.

         There can be no assurance that additional financing (debt or equity),
if required, will be available when needed on terms favorable to the Company, if
at all. If adequate funds are not available on acceptable terms, the Company may
be unable to complete effectively its transition to its new business model,
develop or enhance its services and products, take advantage of future
opportunities or respond to competitive pressures, any of which could have a
material adverse effect on the Company's business, financial condition, results
of operations and prospects.

         As of December 31, 1999, the Company had cash and cash equivalents of
approximately $2.2 million, investments in short term marketable securities of
$1.7 million, and working capital of approximately $15.7 million. Marketable
securities consist of investment grade municipal bonds maturing, on average,
within a year.

         Cash used in operating activities in 1999 totaled approximately $2.8
million, compared to cash provided by operating activities of approximately $1.0
million and $3.3 million in 1998 and 1997, respectively. The decrease in net
cash provided by operations in 1999 was primarily due to an increase over 1998
in cash paid for income taxes of $3.8 million by Omega Research prior to the
Window On WallStreet acquisition, and the overall increase in the income tax
assets related to 1999 losses, partially offset by decreases in accounts
receivable. The decrease in net cash provided by operations in 1998 was
primarily attributable to lower net income of the Company and an increase in
cash paid for income taxes of $1.6 million. The Company began paying taxes in
the fourth quarter of 1997 and, in addition, paid during 1998 the remaining
$900,000 of the $1.8 million tax liability recognized in September 1997.

         The Company's investing activities provided cash of $1.2 million during
1999 and used cash of $6.1 million and $2.0 million in 1998 and 1997,
respectively. During 1999, cash provided from investing activities was made up
of $4.0 million of proceeds from maturity of marketable securities primarily
offset by capital expenditures related to the acquisition of computer and
related equipment and software required to support expansion of the Company's
operations as well as $1.1 million (net of cash acquired) paid for costs
associated with the acquisition of Window on WallStreet. The principal use of
cash in investing activities in 1998 and 1997 was for investments in marketable
securities, net of marketable securities that matured. The balance of such
investing activities during 1998 and 1997 was primarily for capital expenditures
related to the acquisition of computer and related equipment and software
required to support expansion of the Company's operations. During 1997,
investing activities also used cash as a result of purchases of furniture and
fixtures and leasehold improvements related to the Company's move to a new
corporate headquarters in February 1997.

         In 1999, the Company's financing activities used cash of $3.6 million
as compared to cash provided of $190,000 and $10.9 million in 1998 and 1997,
respectively. Net cash used in financing activities during 1999 was related to
the repayment of existing debt of Window On WallStreet of $4.1 million, offset
by proceeds from the issuance of common stock from the Company's 1997 Employee
Stock Purchase Plan and the exercise of stock options under the Company's
Incentive Stock Plan.

         Cash provided during 1998 related primarily to the repayment of the
excess portion of the Dividend distributed on September 30, 1997. See "ITEM 5.
MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS - Dividend
Policy". The balance of the cash provided during 1998 related to the issuance of
common stock from the Company's 1997 Employee Stock Purchase Plan and the
exercise of stock options under the Company's Incentive Stock Plan.

         Cash provided during 1997 of $10.9 million was primarily attributable
to $27.4 million of net proceeds from Omega Research's initial public offering
completed during the fourth quarter of 1997, offset by cash distributions
totaling $16.5 million (net of the 1997 repayment discussed above) to the
Company's S corporation shareholders prior to the Company's initial public
offering. A portion of the distributions was financed with a $15 million
short-term bank loan which was repaid with the proceeds of the initial public
offering.

Recently Issued Accounting Standards

         In June 1999, the Financial Accounting Standards Board issued SFAS No.
137, Accounting for Derivative Instruments and Hedging Activities-Deferral of
FASB Statement No. 133. SFAS No. 137 defers for one year the effective date of
SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS
No. 133 will now apply to all fiscal quarters of all fiscal years beginning
after June 15, 2000. SFAS No. 133, as amended by SFAS No. 138, will require the
Company to recognize all derivatives on the balance sheet as either assets or
liabilities measured at fair value. Derivatives that do not qualify for hedge
accounting must be adjusted to fair value through income. The Company will adopt
SFAS No. 133 effective for the year ended December 31, 2001. The Company
believes that the adoption of SFAS No. 133 will not have a material impact on
its consolidated financial statements, as it has entered into no derivative
contracts and has no current plans to do so in the future.

         In December 1999, the SEC issued Staff Accounting Bulletin No. 101
("SAB 101"), Revenue Recognition in Financial Statements, to provide guidance on
the recognition, presentation and disclosure of revenue in financial statements.
The Company will be required to adopt SAB 101 by the fourth quarter of 2000. The
adoption of SAB 101 is not expected to have a material impact on the financial
statements of the Company.

         In March 2000, the Emerging Issues Task Force reached a consensus on
Issue No. 00-2, Accounting for Web Site Development Costs, which applies to all
web site development costs incurred for the quarters beginning after June 30,
2000. The consensus states that the accounting for specific web site development
costs should be based on a model consistent with AICPA Statement of Position
98-1, Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use. Accordingly, certain web site development costs that are currently
expensed as incurred may be capitalized and amortized. The adoption of Issue No.
00-2 is not expected to have a material impact on the financial statements of
the Company.

Year 2000 Compliance

         The Company has not encountered any significant difficulties with
respect to Year 2000 compliance issues with respect to its customer integrated
support and general ledger system, its telephone system, or any vendor products
or services. See "ITEM 1. BUSINESS - Product Development and Year 2000
Compliance" for a discussion of Year 2000 implications with respect to the
Company's products.

                                       15
<PAGE>

Factors that may cause or contribute to such differences and impact future
events and the results of those events, and business risks of and for the
Company generally, include, but are not limited to, the items described below,
as well as in other sections of this report and in other of the Company's public
filings, and in the Company's press releases, particularly those released during
and subsequent to the 1999 third quarter, any of which could have a material
adverse effect on the business, results of operations, financial condition and
prospects of the Company:

o    Change in Business Model. The Company is in the process of changing its
     business model from a trading strategy client software company to an
     on-line brokerage firm that provides an Internet platform of trading
     strategy tools and streaming real-time market data and news, and trade
     execution through a direct access electronic order execution system. The
     Company has limited experience in the real-time market data industry (all
     of such experience has been acquired by Window On WallStreet, and Window On
     WallStreet had only one year of experience operating a real-time data
     service at the time it was acquired by Omega Research). The Company has no
     experience in the brokerage services industry, and will rely completely
     upon the experience of OnlineTrading.com, assuming and subject to the
     closing of its pending merger with that brokerage firm. OnlineTrading.com
     itself has only been providing brokerage services for approximately four
     years, and mostly to institutional investors (as opposed to the individual
     active traders the Company seeks to attract). The Company's lack of
     experience in key components of its new business model, even after
     considering the experience of Window On WallStreet and, once acquired,
     OnlineTrading.com, is substantial, and may result in delays, mistakes and
     liabilities unlikely to happen to a company that has more experience. Such
     delays, mistakes and liabilities, if and to the extent they occur, may
     cause material adverse effects upon the Company's business, financial
     condition, results of operations and prospects. See "ITEM 1. - BUSINESS -
     Overview and Recent Developments."

     If customer acceptance of the Company's Internet-based trading strategy
     tools, real-time market data services or on-line brokerage services does
     not meet the Company's expectations (due to technical difficulties or
     errors in the products or services, unfavorable critical reviews, failure
     to market effectively, the introduction by others of more-accepted products
     and services, or other reasons), the Company's business, financial
     condition, results of operations and prospects would be materially
     adversely affected. All software, including Internet-based software,
     contains errors, particularly new, highly-complex, innovative products or
     services. Accordingly, there is a substantial risk that the Company's
     Internet-based trading strategy tools, real-time market data services and
     on-line brokerage services in development will contain numerous technical
     errors, some of which may be significant and deeply, negatively impact
     customer acceptance of such products and services.

     The Company's decision to change its business model also means that the
     Company must develop and depend upon a different operational infrastructure
     than the one which supported its client software business, and
     substantially modify its approaches to product development and sales and
     marketing. The Company's infrastructure must be changed to support three
     separate kinds of businesses (development of trading strategy tools,
     organization and delivery of streaming real-time data and news, and on-line
     brokerage services) that need to be seamlessly integrated. This will
     require substantial changes in the Company's information technology and
     databases, its mechanisms and methods of delivery of products and services,


                                       16
<PAGE>

     its administrative functions, and its use of personnel resources. Product
     development must change its focus to a large extent from client software to
     Internet and web site-related technology, sales and marketing must change
     its focus from high-priced client software sales to brokerage services
     (commission revenues) and Internet-based, lower-priced, monthly
     subscriptions for trading strategy tools integrated with streaming
     real-time data and news (monthly subscription revenues). The Company has
     virtually no prior experience in marketing these services, as Omega
     Research has not ever been in those businesses, and Window On WallStreet
     and OnlineTrading.com have engaged in little or no media advertising of
     their respective services. There are substantial risks that the Company
     will fail, to some degree, to sufficiently rebuild its infrastructure and
     integrate the three key components of the new business model (trading
     tools/real-time data/on-line brokerage services), and/or to re-focus its
     product development and sales and marketing on the new business model. Such
     failures, if and to the extent they occur, may cause material adverse
     effects upon the Company's business, financial condition, results of
     operations and prospects. See "ITEM 1. BUSINESS - Products and Services -
     Sales and Marketing and - Product Development and Year 2000 Compliance."

     The Company's transition to its new business model has placed, and will
     continue to place, a significant strain on the Company's management and
     operations. The Company's future operating results will depend, in part, on
     its ability to continue to broaden the Company's senior and middle
     management groups and administrative infrastructure, and its ability to
     attract, hire, and retain skilled employees, particularly in product
     development, marketing and sales, web site design and information
     technology.

     Because the new business model is one with no historical record for the
     Company, and, to the Company's knowledge, one with no historical record for
     any other company, the Company's attempts to anticipate revenues and costs,
     to prepare budgets which organize the implementation of the Company's
     transition to the new business model, and to make decisions regarding
     seeking to obtain third-party financing that may be required, will
     generally be based upon theoretical assumptions. Future events and results
     may differ drastically from those planned or anticipated, which, if
     negative, would result in a material adverse effect on the Company's
     business, financial condition, results of operations and prospects. See
     "Potential Fluctuations in Quarterly Operating Results" below.

     The substantial risks discussed above are magnified by the rapid pace at
     which the Company is attempting to complete the transition to the new
     business model. The Company is assuming that its pending merger with
     OnlineTrading.com will close at the end of 2000 (even though there is risk
     that the merger will close later or not at all) and that its new business
     model will be fully launched in a relatively short period of time after
     closing. If that occurs, the Company will have changed its business
     entirely in a period of approximately one year. This rapid pace obviously
     increases the likelihood of occurrence of the various possible mistakes and
     failures discussed above, and increases the risks of the likelihood of
     resulting material adverse effects that will damage the Company's business,
     financial condition, results of operations and prospects.

o    Failure to Close OnlineTrading.com Merger; Other Risks of Combination With
     OnlineTrading.com. The Company's change to its new business model is
     dependent upon


                                       17
<PAGE>

     closing of its pending merger with OnlineTrading.com. If that merger does
     not occur, the Company's choices would be to modify its new business model
     to exclude on-line brokerage services, to seek to develop arrangements to
     integrate its trading strategy tools/streaming real-time data platform with
     third-party on-line brokers, to search for a different on-line broker with
     which to merge or create a joint venture relationship, or to create its own
     on-line brokerage service. The Company does not believe that excluding
     on-line brokerage services from its new business model or developing
     integration arrangements with third-party on-line brokers are favorable
     alternatives. The Company believes that integrated on-line brokerage
     services are critical in meeting the current and evolving needs of the
     active trader, and that the potential success of the new business model is
     dramatically reduced if it includes only trading strategy tools and
     streaming real-time data without integration of that platform with
     electronic order execution services owned and provided by the Company.
     Further, the Company believes that, in its new business model, brokerage
     commissions are likely to become the Company's largest source of revenues.
     Finding a new on-line broker partner may or may not be feasible, and in all
     cases would cause a huge delay in the Company's transition to its new
     business model. The Company's development of its own on-line brokerage
     services would likely cause an even longer delay, as well as contain the
     additional risk of the Company entering a heavily government-regulated
     business in which it has no prior experience. The merger transaction
     agreements are subject to conditions precedent which, if not fulfilled,
     would result in failure to complete the merger with OnlineTrading.com.
     Those conditions precedent include, but are not limited to, another company
     making a superior proposal to merge with OnlineTrading.com which
     OnlineTrading.com's Board of Directors believes it is duty-bound to accept,
     satisfying all broker-dealer regulatory requirements relating to the merger
     (including NASD approval), approval by the shareholders of the Company and
     of OnlineTrading.com of the merger, the filing with the SEC and
     effectiveness of a registration statement on Form S-4, and the listing of
     the new holding company's shares on The Nasdaq National Market. Failure of
     the merger to occur as and when planned, or at all, would have a material
     adverse effect on the Company's business, financial condition, results of
     operations and prospects. See "ITEM 1. BUSINESS - Overview and Recent
     Developments."

     Assuming the merger does occur, the success of the Company's new business
     model will be dependent, in part, upon the two companies being able to
     rapidly integrate with one another from technological, operational and
     marketing aspects. The two companies are currently working on the
     completion of OnlineTrading.com's first proprietary order routing and
     execution technology, the integration of that technology with
     TradeStation.com (which itself is currently under development) in order to
     be able to provide electronic order execution from the TradeStation.com
     platform, and the required operational, information technology and
     marketing integrations. Given the rapid pace and the number of items
     currently in development, there are substantial risks that the necessary
     completions and integrations will not occur as or when planned, contain
     significant errors or problems, or will not be completed in a manner that
     results in timely commercial viability. To the extent such errors, problems
     or failures occur, they are likely to result in material adverse effects to
     the Company's business, financial condition, results of operations and
     prospects. See "ITEM 1. BUSINESS - Product Development and Year 2000
     Compliance."


                                       18

o    Liquidity Concerns. The Company is experiencing a period of net losses
     which is expected to continue at least through the first quarter of 2001.
     As of March 8, 2000, the Company had less than $4 million in cash, cash
     equivalents and marketable securities to address these current and
     anticipated losses and other cash requirements of the Company as it
     transitions to its new business model. As the Company implements its
     transition to its new business model and thereafter, the Company may need
     to raise additional funds in order to support more rapid expansion, develop
     new or enhanced services and products, respond to competitive pressures,
     acquire necessary or complementary businesses or technologies, and take
     advantage of unanticipated opportunities. The Company has also recently
     substantially increased its rental obligations under real property,
     facilities and equipment leases. The Company's future liquidity and capital
     requirements will depend upon numerous factors, including the period of
     time it takes the Company to execute its transition to its new business
     model, and customer acceptance thereof, costs and timing of expansion of
     research and development and marketing efforts, the success and timing of
     such efforts, the success of the Company's existing and new product and
     service offerings, and competing technological and market developments.
     Funds may be raised through debt financing and/or the issuance of equity
     securities (there being no assurance that any such type of financing on
     terms satisfactory to the Company will occur). Any equity financing or debt
     financing which requires issuance of equity securities or warrants to the
     lender would reduce the percentage ownership of the shareholders of the
     Company. The shareholders may, if issuance of equities occurs, experience
     additional dilution in net book value per share, or the issued equities may
     have rights, preferences or privileges senior to those of the holders of
     the Company's common stock. See "ITEM 7. MANAGEMENT'S DISCUSSION AND
     ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - Liquidity and
     Capital Resources."

o    Potential Fluctuations in Quarterly Operating Results. The Company's
     quarterly revenues and operating results have fluctuated significantly in
     the past, and will likely fluctuate in the future. These fluctuations may
     be expected to be even greater during 2000, and thereafter, due to the
     unpredictability inherent in the Company's change to its new business
     model. Causes of such significant fluctuations may include, but are not
     limited to: the timing, completion (if any) and costs of: (i) the Company's
     merger with OnlineTrading.com, (ii) the Company's development of
     TradeStation.com and other trading strategy platforms, (iii) development of
     OnlineTrading.com's first proprietary electronic order routing and
     execution technology, (iv) the integration of TradeStation.com as a
     platform for OnlineTrading.com's electronic order routing and execution
     technology, (v) modifications by the Company to its infrastructure,
     including information technology and databases, mechanisms and methods of
     delivery of products and services, administrative functions, product
     development and sales and marketing, and (vi) the respective launch dates
     of the various stages of the Company's transition to its new business
     model; cash flow problems that may occur; costs and payment obligations
     associated with debt and/or equity financings, if any; the level of
     product/service and price competition; continuous changes in the Company's
     sales incentive or marketing strategies (which have undergone significant
     change recently and are expected to continue to evolve); changes in demand
     for the Company's products and services; costs that may occur with respect
     to regulatory compliance or other regulatory issues; changes in operating
     expenses; the Company's attempt to enter additional related new markets or
     expand into additional related businesses and the cost, timing and success
     thereof; the incurrence of


                                       19
<PAGE>

     significant costs in one quarter related to revenues anticipated to be
     realized in a subsequent quarter; and general economic and market factors,
     including changes in the securities and financial markets. See "ITEM 7.
     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
     OPERATIONS - Variability of Results."

o    Competition. The markets for (i) on-line brokerage services, (ii) trading
     strategy tools and (iii) real-time market data services are intensely
     competitive and rapidly evolving, and there appears to be substantial
     consolidation of those three products and services occurring in the
     industry. The Company's new business model embraces this evolution and
     consolidation. However, the Company believes that due to the current and
     anticipated rapid growth of the market for integrated trading strategy
     tools, real-time market data and on-line brokerage services, competition,
     as well as consolidation, will substantially increase and intensify in the
     future. The Company believes its ability to compete will depend upon many
     factors both within and outside its control, including the timing and
     market acceptance of new products and services and enhancements developed
     by the Company and its competitors, the ability of the Company to complete
     its pending merger with OnlineTrading.com and to integrate the respective
     businesses in an orderly, efficient and otherwise successful manner,
     product and service functionality, data availability, ease of use, pricing,
     reliability, customer service and support, and sales and marketing efforts.
     See "ITEM 1. BUSINESS - Competition."

o    Exposure to Possible Litigation from Brokerage Customers (Assuming the
     Company Completes its Transition to its New Business Model). Many aspects
     of the securities brokerage business, including on-line trading services,
     involve substantial risks of liability. In recent years there has been an
     increasing incidence of litigation involving the securities brokerage
     industry, including class action and other suits that generally seek
     substantial damages, including in some cases punitive damages. Any such
     litigation could have a material adverse effect on the Company's business,
     financial condition, results of operations and prospects. See "Potential
     Liability to Customers" below.

o    Potential Liability to Customers. The Company's products and services and
     planned products and services are and will be used by traders in the
     financial markets, and, as a result, an investor or trader might claim that
     investment or trading losses or lost profits resulted from use of a flawed
     version of one of the Company's trading tools or inaccurate assumptions
     made by the trading tools regarding data, or inaccurate data, which could
     result in litigation against the Company. This risk was heightened by the
     Company's decision to provide financial market information to its
     customers, which routinely contain errors and omissions, but which are
     nevertheless relied upon by customers in making investment and trading
     decisions using the Company's trading tools. This risk will again be
     substantially heightened by the Company's planned offering, if and when it
     occurs, of brokerage services, which will likely result in certain
     brokerage customers from time to time asserting that the Company's acts or
     omissions (or that errors or inaccuracies in the Company's trading tools or
     market data) have caused such customers losses or lost profits.
     Contributing to these possible occurrences are risks that the electronic
     communications and other systems upon which the Company's products and
     services rely, and will continue to rely, may operate too slowly or fail.
     Major failures of this kind will affect all of the Company's customers who
     are on-line simultaneously, possibly resulting in a class action lawsuit
     being filed against the Company. In addition, there can be no assurance
     that the Company's Year 2000 compliance efforts, or


                                       20
<PAGE>

     that compliance modifications, have not and will not adversely affect the
     Company's products and services in ways not anticipated by the Company, or
     that customers will not assert that the Company has or had an obligation to
     provide Year 2000 solutions for older versions of existing products or for
     discontinued products, any of which occurrences could result in claims by
     customers. Any such litigation could result in substantial damages and
     significant costs to the Company in terms of the deployment of its
     financial and managerial resources. See "Exposure to Possible Litigation
     from Brokerage Customers (Assuming the Company Completes its Transition to
     its New Business Model)" above, "Systems Failure (Assuming the Company
     Completes its Transition to its New Business Model)" below and "ITEM 1.
     BUSINESS - Product Development and Year 2000 Compliance."

o    Risks Associated with Reliance on the Internet. The Company's change in its
     business model means that the future growth of the Company will depend upon
     it continuing to adopt the Internet as its primary medium for commerce and
     communication, including the delivery of browser-based trading tools,
     high-quality streaming real-time market data, on-line electronic trade
     routing and execution systems, and comprehensive web sites that include
     discussion forums, chat rooms, educational content, marketing materials and
     customer support. There can be no assurance that the Company will
     successfully develop and implement such Internet capabilities, or
     effectively adjust its marketing and customer support approaches. Further,
     the Company is and will be relying increasingly on its web sites and
     related systems, and the Internet generally, to maximize the use and
     cost-efficiency of its products and services, to accept orders and
     payments, to track and account for orders and payments and fulfill
     reporting obligations under regulatory laws and marketing agreements with
     third parties, to register attendees for events, to market its products and
     services, and to provide technical information and assistance to its
     customers. In addition to the risk that the Company may not adequately
     transition its business to the Internet, there is the risk that, over time,
     the Internet may not prove to be a viable commercial marketplace because of
     a failure to continue to develop the necessary infrastructure, such as
     reliable network backbones and adequate band-widths, or the failure to
     develop complementary services, such as high-speed modems. The Internet has
     experienced, and is expected to continue to experience, significant growth
     in the number of users and amount of traffic. There can be no assurance
     that the Internet infrastructure will continue to be able to support the
     demands placed on it by this continued growth. See "ITEM 1. BUSINESS -
     Products and Services and - Sales and Marketing."

o    Systems Failure (Assuming the Company Completes its Transition to its New
     Business Model). As an on-line brokerage, the Company will receive and
     process trade orders through Internet-based trading platforms and on-line
     order execution systems. Thus, the Company will depend heavily on the
     integrity of the electronic systems supporting this type of trading,
     including the trading strategy tools containing buy and sell alerts that
     initiate trading decisions or order placement. Heavy stress placed on these
     systems during peak trading times could cause these systems to operate too
     slowly or fail. Additionally, the integrity of these systems is
     increasingly being attacked by persons sometimes referred to as "hackers"
     who intentionally introduce viruses or other defects to cause damage,
     inaccuracies or complete failure. If these systems or any other systems in
     the trading process slow down significantly or fail even for a short time,
     the Company's brokerage customers would suffer delays in trading,
     potentially causing substantial losses and possibly subjecting the Company
     to claims for such losses or to litigation claiming fraud or negligence.
     During a systems


                                       21
<PAGE>

     failure, the Company may be able to take orders by telephone, however, only
     associates with appropriate securities broker's licenses can accept
     telephone orders, and an adequate number of associates may not be available
     to take customer calls in the event of a systems failure. In addition, a
     hardware or software failure, power or telecommunications interruption or
     natural disaster could cause a systems failure. Any systems failure that
     interrupts the Company's operations could have a material adverse effect on
     its business, financial condition, results of operations and prospects. See
     "Potential Liability to Customers" and "Exposure to Possible Litigation
     from Brokerage Customers (Assuming the Company Completes its Transition to
     its New Business Model)" above.

o    Risks Associated with Fluctuations in the Securities and Financial Markets.
     The Company's current and planned products and services are and will be
     marketed to customers who invest or trade in the securities and financial
     markets. To the extent that interest in investing or trading decreases due
     to volatility in the securities or financial markets, tax law changes,
     recession, depression, or otherwise, the Company's business, financial
     condition, results of operations and prospects could be materially
     adversely affected. It is possible, if not likely, that increased losses by
     customers that occur as a result of any such recession, depression or other
     negative event will increase the quantity and size of legal claims made
     against the Company. See "Potential Liability to Customers" and "Exposure
     to Possible Litigation from Brokerage Customers (Assuming the Company
     Completes its Transition to its New Business Model)" above.

o    Operation in a Highly Regulated Industry and Compliance Failures (Assuming
     the Company Completes its Transition to its New Business Model). The
     securities industry in the U.S., Canada and the other jurisdictions in
     which the Company may operate is subject to extensive regulation covering
     all aspects of the securities business. Regulatory authorities are
     currently focusing intensely on the on-line trading industry, particularly
     the segment that seeks the accounts of active traders by offering
     well-integrated, sophisticated trading platforms and order execution. The
     various government authorities and industry self-regulatory organizations
     that will supervise and regulate the Company generally have broad
     enforcement powers to censure, fine, issue cease-and-desist orders or
     suspend, enjoin or expel the Company or any of its officers or employees
     who violate applicable laws or regulations. Additionally, new rules
     relating to active traders may be enacted which severely limit the
     operations and potential success of the Company's new business model. The
     Company's ability to comply with all applicable laws and rules is largely
     dependent on the Company's establishment and maintenance of compliance and
     reporting systems, as well as its ability to attract and retain qualified
     compliance and other personnel. The Company could be subject to
     disciplinary or other regulatory or legal actions in the future due to
     noncompliance. In addition, it is possible that any past noncompliance of
     OnlineTrading.com could subject the Company to future civil lawsuits or
     regulatory actions, the outcome of which could have a material adverse
     effect on the Company's financial condition and operating results. See
     "ITEM 1. BUSINESS - Overview and Recent Developments" and - "Government
     Regulation."

o    Dependence Upon Outside Data Sources. The Company's business is dependent
     upon its ability to enter into contracts with private business information
     compilers in order to provide market data and news to its customers. The
     Company obtains such information pursuant to


                                       22
<PAGE>

     non-exclusive licenses from private information compilers, some of which
     are current or potential competitors of the Company. The private sector
     contracts typically provide for royalties based on usage or minimums. The
     Company has such licenses from certain data suppliers to provide such
     information that such suppliers also market in competition with the
     Company. The Company must also comply with rules and regulations of the
     exchanges that are the sources of market data information. Failure to
     comply could result in the Company becoming a prohibited recipient of
     market data from exchanges the rules or regulations of which were violated.
     While the Company is not aware of any material data supplier contracts that
     are in jeopardy of being terminated or not renewed, there can be no
     assurance that the Company will be able to renew its current contracts with
     data sources, maintain comparable price levels for information, or
     negotiate additional contracts with data sources as necessary to maintain
     existing products and services or introduce new products and services.
     There is no assurance comparable alternative sources of information could
     be obtained should existing contracts be terminated or not renewable.
     Termination of the Company's relationship with one or more information
     suppliers could have a material adverse effect on the Company's operations.
     See "ITEM 1. BUSINESS - Products and Services" and "Systems Failures
     (Assuming the Company Completes its Transition to its New Business Model)"
     and "Potential Liability to Customers" above.

o    Dependence on Key Employees. The Company's success depends to a very
     significant extent on the continued availability and performance of a
     number of senior management, engineering and sales and marketing personnel.
     The loss of one or more of these key employees, including William R. Cruz
     or Ralph L. Cruz, the Company's Co-Chief Executive Officers, or of certain
     key technology personnel, could have a material adverse effect on the
     Company. See "ITEM 1. BUSINESS - Employees."

o    Dependence on Relationship with Bridge Telerate. The Company is party to a
     Software License, Maintenance and Development Agreement with Bridge
     Telerate relating to TradeStation. The agreement provides a substantial
     minimum royalty stream through January 12, 2002, the loss of which would
     materially adversely affect the Company's revenues and earnings (or size of
     its losses) in those years. While the agreement is non-cancelable, there
     can be no assurance that the Company's anticipated royalties and other
     anticipated benefits from its relations with Bridge Telerate will be
     realized. See "Liquidity Concerns" above and "ITEM 1. BUSINESS - Strategic
     Relationships."

o    Net Capital Requirements (Assuming the Company Completes its Transition to
     its New Business Model). The SEC, the NASD and various other regulatory
     agencies have stringent rules with respect to the maintenance of specific
     levels of net capital by securities broker-dealers. Net capital is the net
     worth of a broker or dealer (assets minus liabilities), less deductions for
     certain types of assets as well as other charges. If a firm fails to
     maintain the required net capital it may be subject to suspension or
     revocation of registration by the SEC and suspension or expulsion by the
     NASD, and it could ultimately lead to the firm's liquidation. If such net
     capital rules are changed or expanded, or if there is an unusually large
     charge against net capital, operations that require the use of capital
     would be limited. Such operations may include trading activities and the
     financing of customer account balances. Also, the Company's ability to
     withdraw capital from its future brokerage subsidiary (OnlineTrading.com)
     is restricted under SEC rules, which in turn could materially


                                       23
<PAGE>

     impact the Company's available working capital and materially impact or
     limit the Company's ability to repay debt as and when due, redeem or
     purchase shares of the Company's outstanding stock, if required, and pay
     dividends in the future. A large operating loss or charge against net
     capital could adversely affect the Company's ability to expand or even
     maintain its then present levels of business, which could have a material
     adverse effect on the Company's business, financial condition, results of
     operations and prospects. See "Liquidity Concerns" above, and "ITEM 1.
     BUSINESS - Government Regulation."

o    Internet Business Risks Relating to Customer Privacy and Security and
     Increasing Regulation. A significant risk for the Company's existing and
     planned Internet operations is that customers may refuse to transact
     business over the Internet due to privacy or security concerns. The Company
     currently incorporates and plans to incorporate security measures into its
     privacy policy. However, a major breach of customer privacy or security
     could have serious consequences for the Company's Internet-based
     operations. Use of the Internet, particularly for commercial transactions,
     may not continue to increase as rapidly as it has during the past few years
     as a result of privacy or security concerns, or for other reasons. If this
     occurs, the growth of the Company's Internet-based operations would be
     materially hindered. If Internet activity becomes heavily regulated in
     these respects, that could also have significant negative consequences for
     the growth of the Company's current and planned Internet-based operations.
     See "Risks Associated with Reliance on the Internet" above and "ITEM 1.
     BUSINESS - Government Regulation."

o    Risk of Intellectual Property Litigation. There has been substantial
     litigation in the software industry involving intellectual property rights.
     Although the Company does not believe that it is or will be infringing the
     intellectual property rights of others, there can be no assurance that
     infringement claims, if asserted, would not have a material adverse effect
     on the Company's business, financial condition and results of operations,
     or result in the Company being unable to use intellectual property which is
     integral to one or more of its products or services. The risk of
     infringement claims against the Company is heightened with respect to its
     new business model technology in development, as such will not have stood
     any "test of time" as has the Company's client software technology. See
     "ITEM 1. BUSINESS - Intellectual Property."

o    Intellectual Property. The Company's success is and will be heavily
     dependent on its proprietary technology, including its existing trading
     tools, as well as trading tool, Internet, web site and order execution
     technology currently in development. The Company views its technology as
     proprietary, and relies, and will be relying, on a combination of
     copyright, trade secret and trademark laws, nondisclosure agreements and
     other contractual provisions and technical measures to protect its
     proprietary rights. Policing unauthorized use of the Company's products and
     services is difficult, however, and the Company is unable to determine the
     extent to which piracy of its products and services exists. There can be no
     assurance that the steps taken by the Company to protect its proprietary
     rights will be adequate or that the Company's competitors will not
     independently develop technologies that are substantially equivalent or
     superior to the Company's technologies or products and services. See "ITEM
     1. BUSINESS - Intellectual Property."

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


To Omega Research, Inc.:

     We have audited the accompanying consolidated balance sheets of Omega
Research, Inc. (a Florida corporation) and subsidiaries as of December 31, 1999
and 1998, and the related consolidated statements of operations, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1999 (as restated - see Note 2). 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 auditing standards generally
accepted in the United States. 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 Omega Research, Inc. and
subsidiaries as of December 31, 1999 and 1998, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1999 in conformity with accounting principles generally accepted in
the United States.

                      OMEGA RESEARCH, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1) DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Description of Business

    Omega Research, Inc. ("Omega Research" or, together with its subsidiaries,
the "Company"), a Florida corporation, was incorporated in 1982 to develop,
market and sell trading strategy tools to individual and professional investors
and traders. The Company's products and services provide investors and traders
with the ability to develop, historically test and computer automate trading
strategies and to access streaming real-time charts, quotes and news via the
Internet.

    The following is a summary of significant accounting policies followed in
the preparation of these financial statements:

    Principles of Consolidation

    The consolidated financial statements include the accounts of the Company
and its direct and indirect wholly owned subsidiaries, Window on WallStreet Inc.
("Window On WallStreet") and Direct XChange Securities, Inc., since the
acquisition of such subsidiaries on October 26, 1999. All significant
intercompany transactions have been eliminated in consolidation.

    Cash and Cash Equivalents

    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents. Cash and cash
equivalents consist primarily of overnight investments, tax exempt commercial
paper and short-term municipal bonds with an original maturity of three months
or less.

    Marketable Securities

    Marketable securities consist of investment grade municipal bonds maturing,
on average, within a year. The cost of these investments approximates fair
market value and management has designated the securities as available for sale.

    Accounts Receivable

    As of December 31, 1999, accounts receivable are primarily comprised of
receivables earned under royalty agreements with entities that market and sell
financial market data subscriptions (see Other Revenues below and Note 12). The
Company performs periodic credit evaluations and maintains allowances for
potential credit losses of approximately $716,000 and $3.7 million at December
31, 1999 and 1998, respectively, and allowances for potential returns of
approximately $83,000 and $7.4 million at December 31, 1999 and 1998,
respectively.


                                      F-8
<PAGE>

    The Company provides all client software customers with a 30-day right of
return and, prior to 1999, recorded a provision for anticipated returns at the
time of sale in accordance with Statement of Financial Accounting Standards
("SFAS") No. 48, Revenue Recognition When Right of Return Exists. To maintain a
positive, customer-friendly environment, the Company has historically accepted
returns in excess of 30 days. Approximately, 90% of all returns accepted under
the 30-day right of return policy are initiated within 60 days following the
date of sale. The reserve for returns and the provision for bad debts are
estimated based on historical experience and other relevant information.

    Fair Value of Financial Instruments

    The carrying amounts of cash and cash equivalents, marketable securities,
accounts receivable and accounts payable approximate fair value as of December
31, 1999 and 1998.

    Inventory

    Inventory, which consists primarily of software media, manuals and related
packaging materials, are stated at the lower of cost or market with cost
determined on a first-in, first-out ("FIFO") basis.

    Property and Equipment

    Property and equipment are stated at cost less accumulated depreciation.
Property and equipment are depreciated using the straight-line method over the
estimated useful lives of the assets.

    Maintenance and repairs are charged to expense when incurred; betterments
are capitalized. Upon the sale or retirement of assets, the cost and accumulated
depreciation are removed from the accounts, and any gain or loss is recognized
currently.

    Software Development Costs

    In accordance with SFAS No. 86, Accounting for the Cost of Capitalized
Software to be Sold, Leased or Otherwise Marketed, the Company examines its
software development costs after technological feasibility has been established
to determine the amount of capitalization that is required. Based on the
Company's product development process, technological feasibility is established
upon completion of a working model. The costs that are capitalized are amortized
on the straight-line basis over a one-year period, the period of benefit, of the
related products. For certain periods, the technological feasibility of the
Company's products and the general release of such software substantially
coincide, and, as a result, software development costs qualifying for
capitalization are immaterial. There were no capitalized software development
costs as of December 31, 1999 or 1998.

    Goodwill and Other Intangible Assets

    Goodwill and other intangible assets are stated at cost less accumulated
amortization and are amortized using the straight-line method. Goodwill is being
amortized over four years. Other intangible assets are being amortized over
three to four years.


                                      F-9
<PAGE>

    Long-Lived Assets

    The Company reviews long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable.

    Revenue Recognition

    Licensing fees

    Prior to 1999, sales of client software products, net of provisions for
anticipated returns, were recognized at the time the product was shipped, in
accordance with the provisions of the American Institute of Certified Public
Accountants Statement of Position ("SOP") 97-2, Software Revenue Recognition and
an estimate for returns was provided in accordance with SFAS No. 48.

    Beginning in 1999 with the launch of the Company's 2000i product line,
changes in the Company's client software product sales, including introduction
of a new, higher-priced product and longer financing terms, were deemed to alter
the predictability of return reserves and the future collectibility of
receivables. Accordingly, all 2000i product sales are recognized as they become
due (generally over a period of up to 12 months and, for Omega Research ProSuite
2000i sales, over the course of up to 16 months).

    While the Company has no obligation to perform future services subsequent to
shipment of client software, for a limited time, the Company voluntarily
provides support on its web site, periodic "bug" fixes and telephone and
electronic mail customer support as an accommodation to purchasers of its
products as a means of fostering customer satisfaction. The majority of such
services are provided during the first 60 days of ownership of the Company's
products. Costs associated with this effort are insignificant in relation to
product sales value and are accrued at the date the software is delivered in
accordance with SOP 97-2.

    Certain products have been sold with bundled services (see discussion of
Other Revenues below). The portion of software sales related to such bundled
services are deferred and recognized as revenue on a monthly basis as the
service is provided.

    Other Revenues

    The Company has, with respect to its client software products, entered into
certain agreements with entities that market and sell financial market data
subscriptions. Except for the agreement described in Note 12 (which is a royalty
arrangement), the Company receives, in certain cases, monthly payments in the
nature of commissions based on the use by the Company's client software
customers of financial market data feed subscriptions which are accessed through
one of the Company's client software products. The Company records these
revenues as they are earned in accordance with the terms of the applicable
contracts.

    In addition, the Company provides streaming real-time market information via
the Internet through the Financial Data Cast Network ("FDCN") acquired in the
Window On WallStreet acquisition. Revenue is recognized on a monthly basis as
the service is provided. Payments


                                      F-10
<PAGE>

received in advance of service are deferred and recognized on a monthly basis as
the services are provided.

    Advertising Costs

    Advertising costs are expensed when the initial advertisement is run, and
are included in sales and marketing expenses in the accompanying statements of
operations. Advertising costs for the years ended December 31, 1999, 1998 and
1997 were $5.6 million, $5.8 million and $5.4 million, respectively.

     Stock-Based Compensation

    In accordance with SFAS No. 123, Accounting for Stock-Based Compensation, in
accounting for stock-based transactions with non-employees, the Company records
compensation expense in the statement of operations when these types of options
are issued. As permitted by SFAS No. 123, the Company accounts for its
stock-based compensation paid to employees in accordance with Accounting
Principles Board ("APB") Opinion No. 25. See Note 8.

    Income Taxes

    For income tax purposes, the Company was an S corporation prior to September
30, 1997. Accordingly, net income and related timing differences which arose in
the recording of income and expense items for financial reporting and tax
reporting purposes were included in the individual tax returns of the S
corporation shareholders. Effective September 30, 1997, the Company terminated
its S corporation election, and, as a result, adopted SFAS No. 109, Accounting
for Income Taxes. SFAS No. 109 requires that deferred income tax balances be
recognized based on the differences between the financial statement and income
tax bases of assets and liabilities using the enacted tax rates. See Note 9.

    Pro Forma Income Tax Adjustments

    The pro forma income tax adjustments included in the accompanying statement
of operations for the year ended December 31, 1997 are for informational
purposes only. Pro forma income taxes have been provided at an estimated
effective rate of 39.5% for Omega Research for periods prior to September 30,
1997. In addition, a non-recurring tax credit of $1.2 million has been excluded
from pro forma net income. See Note 9.

    (Loss) Earnings Per Share

    (Loss) earnings per share is calculated in accordance with SFAS No. 128,
Earnings per Share. SFAS No.128 requires presentation of basic and diluted
(loss) earnings per share on the face of the statement of operations. Basic
(loss) earnings per share is computed by dividing the net (loss) income
available to common shareholders by the weighted average shares of outstanding
common stock. The calculation of diluted (loss) earnings per share is similar to
basic (loss) earnings per share except that the denominator includes dilutive
common stock equivalents such as stock options and warrants. See Note 11.


                                      F-11
<PAGE>

Use of Estimates

    The preparation of financial statements in conformity with accounting
principles generally accepted in the United States 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 expenses
during the reporting period. Actual results could differ from those estimates.
Such estimates include established reserves for returns and reserves for
potentially uncollectible accounts receivable.

    Computer Software Developed or Obtained for Internal Use

     Computer software developed or obtained for internal use is accounted for
in accordance with SOP 98-1, Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use. SOP 98-1 establishes criteria for
determining which costs of developing or obtaining internal-use computer
software should be charged to expense and which should be capitalized. The
Company adopted SOP 98-1 prospectively effective January 1, 1999. Such adoption
did not have a material effect on the Company's financial position or results of
operations.

    Comprehensive Income

    Comprehensive income is defined as the change in a business enterprise's
equity during a period arising from transactions, events or circumstances
relating to non-owner sources, such as foreign currency translation adjustments
and unrealized gains or losses on available-for-sale securities. It includes all
changes in equity during a period except those resulting from investments by or
distributions to owners. Comprehensive (loss) income is equal to net (loss)
income for all periods presented.

    Segment Information

    Segment information is required to be presented in accordance with SFAS No.
131, Disclosures about Segments of an Enterprise and Related Information. SFAS
No. 131 is based on a management approach, which requires segmentation based
upon the Company's internal organization and disclosure of revenue and operating
income based upon internal accounting methods. During the three years ended
December 31, 1999, management evaluated and operated the business of the Company
as a single segment. See Note 13.

    New Accounting Pronouncements

    In June 1999, the Financial Accounting Standards Board issued SFAS No. 137,
Accounting for Derivative Instruments and Hedging Activities-Deferral of FASB
Statement No. 133. SFAS No. 137 defers for one year the effective date of SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities. SFAS No.
133 will now apply to all fiscal quarters of all fiscal years beginning after
June 15, 2000. SFAS No. 133, as amended by SFAS No. 138, will require the
Company to recognize all derivatives on the balance sheet as either assets or
liabilities measured at fair value. Derivatives that do not qualify for hedge
accounting must be adjusted to fair value through income. The Company will adopt
SFAS No. 133 effective for the


                                      F-12
<PAGE>

year ended December 31, 2001. The Company believes that the adoption of SFAS No.
133 will not have a material impact on its consolidated financial statements, as
it has entered into no derivative contracts and has no current plans to do so in
the future.

    In December 1999, the SEC issued Staff Accounting Bulletin No. 101 ("SAB
101"), Revenue Recognition in Financial Statements, to provide guidance on the
recognition, presentation and disclosure of revenue in financial statements. The
Company will be required to adopt SAB 101 by the fourth quarter of 2000. The
adoption of SAB 101 is not expected to have a material impact on the financial
statements of the Company.

    In March 2000, the Emerging Issues Task Force reached a consensus on Issue
No. 00-2, Accounting for Web Site Development Costs, which applies to all web
site development costs incurred for the quarters beginning after June 30, 2000.
The consensus states that the accounting for specific web site development costs
should be based on a model consistent with AICPA Statement of Position 98-1,
Accounting for the Costs of Computer Software Developed or Obtained for Internal
Use. Accordingly, certain web site development costs that are currently expensed
as incurred may be capitalized and amortized. The adoption of Issue No. 00-2 is
not expected to have a material impact on the financial statements of the
Company.

(2)  RESTATEMENT

     Subsequent to the filing of the Company's Consolidated Financial Statements
for each of the three years ended December 31, 1999 on Form 10-K and in
connection with its review of a registration statement on Form S-4 related to
the proposed merger with onlinetradinginc.com corp. ("OnlineTrading.com") (see
Note 15), the Staff of the Securities and Exchange Commission ("SEC") expressed
concern about the method of accounting for revenue recognition of licensing fees
used by the Company and its method of accounting for the acquisition of Window
On WallStreet. As a result of consultation with the Staff of the SEC, the
Company restated certain of its annual and quarterly financial statements as
discussed below.

     Beginning in 1999, with the launch of the Company's 2000i product line,
changes in the Company's client software product sales, including introduction
of a new, higher-priced product and longer financing terms, were deemed to alter
the predictability of return reserves and the future collectibility of
receivables. Accordingly, all 2000i product sales are recognized as they become
due (generally over a period of up to 12 to 16 months). Prior to 1999, sales of
client software products were recognized, net of anticipated returns, at the
time the product was shipped. In addition, the Company's acquisition of Window
On WallStreet has been restated to be accounted for under the purchase method of
accounting. A summary of the effects of the restatement for the three-year
period ended December 31, 1999 is as follows:

    The revenue recognition timing changes do not impact revenue recognition for
the Company's Internet subscription services or other revenues, or any of the
Company's planned service offerings, which are expected to generate the majority
of the Company's revenues in the future. The amounts reported for 1997 and 1998
are the same as the Company had previously reported prior to the Window On
WallStreet acquisition in its Annual Report on Form 10-K for the year ended
December 31, 1998 filed with the SEC on March 30, 1999.

(3)  ACQUISITION

    Effective October 26, 1999, the Company acquired Window On WallStreet, a
leading provider of Internet-based streaming real-time market data and a
developer of client software and on-line trading strategy tools. Under the terms
of the merger agreement, Window On WallStreet shareholders received 1,999,995
newly issued shares of the Company's common stock for all of the issued and
outstanding shares of Window On WallStreet's common stock. In addition, the
Company (i) repaid in accordance with its terms approximately $4.1 million of
debt, (ii) assumed all outstanding stock options to purchase Window On
WallStreet common stock which, based on an exchange ratio of 0.210974, were
exercisable for an aggregate of 182,529 shares of the Company's common stock and
issued to employees 335,000 stock options to purchase the Company's common
stock, and (iii) paid fees and costs relating to the acquisition of $1.2

million. The consolidated financial statements contained herein reflect this
acquisition under the purchase method of accounting.

    At the acquisition date, the shares of the Company's common stock issued
were valued at $8.6 million and the options were valued at $1.5 million. The
resulting goodwill of $1.6 million and identifiable intangible assets of $15.0
million are being amortized over a period of three to four years. See Note 5.

are included from the acquisition date forward. Accordingly, the consolidated
financial statements include the results of operations of Window on WallStreet

(8) SHAREHOLDERS' EQUITY

    Share Split

    Effective January 29, 1997, the Company authorized an increase in the amount
of its authorized common stock to 100 million shares and changed the par value
of each share to $.01. In addition, on January 30, 1997, the Company declared a
97,400-for-1 split of its outstanding common stock. The split has been
retroactively reflected in the financial statements for all periods presented.

    Preferred Stock

    On July 16, 1997, the Company authorized 25 million shares of preferred
stock with a par value of $.01 per share. No specific preferences or rights have
been established to date with respect to any of these shares nor have any of
these shares been issued.

    Initial Public Offering

    On October 6, 1997, the Company closed its initial public offering of 2.6
million shares of common stock of the Company at $11.00 per share (the "Initial
Public Offering"). On November 5, 1997, the Company closed the underwriters'
purchase of 158,108 additional shares of common stock pursuant to the exercise
of a portion of their over-allotment option granted in the Initial Public
Offering. Total proceeds to the Company, net of underwriting discounts and
offering expenses of approximately $2.9 million, were $27.4 million.

    Distributions to Shareholders

    On September 30, 1997, the Company terminated its S corporation status and
the Company became a C corporation making it subject to federal and state income
taxes on its earnings. In conjunction with the Company becoming a C corporation,
the Company declared and paid a cash dividend to the Company's existing
shareholders of $15.4 million (the "Dividend"). The Dividend was equal to the
Company's estimate at that time of its cumulative taxable income prior to its
conversion to a C corporation to the extent such taxable income had not been
previously distributed. Subsequent to the payment of the Dividend, the Company
preliminarily determined that the actual cumulative taxable income would be less
than was originally estimated. Accordingly, in the fourth quarter of 1997, the
recipients of the Dividend repaid $800,000, plus interest, to the Company.
During the third quarter of 1998, upon finalization of the Company's 1997 tax
returns and final determination of S corporation earnings at the date of
conversion to a C corporation, the recipients of the Dividend repaid an
additional $135,000, plus interest, to the Company, reducing the Dividend to
$14.5 million.

    Stock Option Plans

    The Company has reserved 4,500,000 shares of its common stock for issuance
under its Amended and Restated 1996 Incentive Stock Plan, as amended (the
"Option Plan"). Under the Option Plan, incentive and nonqualified stock options,
stock appreciation rights, stock awards, performance shares and performance
units are available to employees or consultants of the Company. Currently, only
options have been granted. The terms of each option agreement are


                                      F-17
<PAGE>

determined by the Compensation Committee of the Board of Directors. The exercise
price of incentive stock options may not be less than fair market value at the
date of grant and their terms may not exceed ten years. The options issued under
the Option Plan generally vest ratably over a five-year period. In January 2000,
the Board of Directors, as part of its authorization of the Merger Agreement
(see Note 15) with OnlineTrading.com authorized an increase, subject to approval
by the Company's shareholders of the Merger Agreement and the merger with
OnlineTrading.com, in the number of shares of common stock reserved for issuance
under the Option Plan from 4,500,000 to 7,500,000, subject to future
anti-dilution adjustments.

    The Company has reserved 175,000 shares of its common stock for issuance
under its 1997 Director Stock Option Plan, as amended (the "Director Plan").
Under the Director Plan, an independent director is awarded an initial grant of
up to 75,000 non-qualified stock options and annual grants of up to 3,000
non-qualified stock options. The terms of each option grant are determined by
the Board of Directors.

    As discussed in Note 3, the Company assumed all outstanding stock options to
purchase Window On WallStreet common stock ("WOW Options"). The WOW Options
generally vest ratably over a four-year period and their terms are ten years.

    A summary of stock option activity including stock options granted under the
Option Plan and the Director Plan is as follows:

    All options issued during 1996 were issued to key employees at an exercise
price that was subsequently determined to be approximately $291,000 in the
aggregate below fair market value at the date of grant as determined by an
independent appraisal. Several of the options issued during 1997 were determined
to be, in the aggregate, approximately $341,000 below fair value as determined
by an independent appraisal. These differences are being amortized over the
five-year vesting period of the related stock options. For the years ended
December 31, 1999, 1998 and 1997, the Company recorded compensation expense of
approximately $141,000, $114,000 and $122,000, respectively.

    Included in compensation expense in 1999, 1998 and 1997 was approximately
$5,000, $7,000 and $23,000, respectively, related to options issued to
consultants of the Company, accounted for under the provisions of SFAS No. 123.
Such options were issued in connection with the procurement of training services
and product content. The exercise prices of the consultant option grants in
1999, 1998 and 1997 were $5.97, $1.66 and $11.00, respectively, and the option
grants vest over a period of 3-years, 5-years and 6-months, respectively. The
fair values of these grants at the date of issue were $102,000, $2,000 and
$31,000, respectively. In determining the fair value of these grants, the
assumptions set forth below for employee option grants were used in the
application of the Black-Scholes model for these grants except for the weighted
average life of three years used for the 1997 grant. The provisions of Emerging
Issues Task Force ("EITF") 96-18, Accounting for Equity Instruments That Are
Issued to Other Than Employees for Acquiring, or in conjunction with Selling,
Goods or Services were applied in determining the amount of expense recorded in
each of the periods noted above.

    Options to purchase 930,360, 323,450 and 110,900 shares were exercisable at
December 31, 1999, 1998 and 1997, respectively.

    The Company, as permitted by SFAS No. 123, applies APB Opinion No. 25 for
options granted to employees. Accordingly, no compensation is recognized for
such grants to the extent that their exercise price is equal to the fair market
value of the underlying stock at the date of grant. Had compensation cost for
the Company's stock options been based on fair value at the

grant dates consistent with the methodologies of SFAS No. 123, the Company's pro
forma net loss (and pro forma loss per share) would have been approximately $4.6
million ($0.20 per share) for the year ended December 31, 1999 and pro forma net
income (and pro forma earnings per share on a diluted basis) would have been and
$1.4 million ($0.06 per share) and $5.2 million ($0.25 per share) for the years
ended December 31, 1998 and 1997, respectively. The fair value of each option
grant is estimated on the date of grant using the Black-Scholes model with the
following assumptions:

Employee Stock Purchase Plan

    In July 1997, the Board of Directors of the Company adopted and the
shareholders approved the 1997 Employee Stock Purchase Plan (the "Purchase
Plan") and reserved 500,000 shares of common stock pursuant to the exercise of
nontransferable options granted to participating employees. The exercise price
for the options for each six-month Purchase Plan period is 85% of the lesser of
the fair market value of the Company's common stock on the first or last
business day of the Purchase Plan period. The Purchase Plan provides for the
first options to be granted for the Purchase Plan period which commenced January
1, 1998. During the years ended December 31, 1999 and 1998, 23,585 and 12,506
shares of common stock were issued under the plan at an average price of $3.27
and $3.06, respectively.

    At December 31, 1999, the Company had an income tax receivable of
approximately $589,000 which will be realized upon filing 1999 tax returns. The
realizability of the deferred tax assets is based primarily upon the Company's
ability to carryback its expected tax loss during 2000 to recoup approximately
$8.6 million of federal income taxes paid during 1998 and 1999. The remaining
deferred tax assets are expected to be realized through future taxable income.

    The Company has available net operating loss carryforwards totaling
approximately $6.7 million (through its acquisition of Window On WallStreet),
which will begin to expire in 2012. The Company also has tax credit
carryforwards totaling approximately $100,000, which will begin to expire in
2012. The utilization of these net operating losses and tax credits will be
subject to limitations of approximately $518,000 per year which are cumulative
to the extent not utilized by the Company. The deferred tax asset related to
these carryforwards has been reduced to zero by a valuation allowance.

    A reconciliation of the difference between the expected (benefit) provision
for income taxes using the statutory Federal tax rate and the Company's actual
(benefit) provision is as follows:

    The effective tax rates for 1999 and 1998 were 39% and 35%, respectively.

    For income tax purposes, the Company was an S corporation prior to September
30, 1997. Accordingly, net income and related timing differences which arose in
the recording of income


                                      F-21
<PAGE>

and expense items for financial reporting and tax reporting purposes were
included in the individual tax returns of the S corporation shareholders.
Effective September 30, 1997, the Company terminated its S corporation election.
The $1.2 million benefit for income taxes recorded during the third quarter of
1997 is comprised of a non-recurring deferred income tax credit (the "SFAS 109
Credit") of approximately $3.0 million partially offset by a $1.8 million
provision for income taxes payable. The SFAS 109 Credit recognized net deferred
tax assets arising from book and tax basis differences that arose primarily as a
result of accounts receivable reserves. The $1.8 million in income taxes payable
relate to federal and state income taxes owed by the Company as a result of an
approximate $4.6 million in S corporation taxable earnings paid by the Company
during the fourth quarter of 1997 and the year-ended December 31, 1998.

(10)  EMPLOYEE BENEFIT PLAN

    The Company provides retirement benefits through a defined contribution
401(k) plan (the "401(k) Plan") which was established during 1994. Employees
become eligible based upon meeting certain service requirements. The Company
matches employee contributions based upon a formula defined in the 401(k) Plan.
Matching contributions accrued under the 401(k) Plan amounted to approximately
$242,000, $0 and $63,000 in 1999, 1998 and 1997, respectively.

(12) COMMITMENTS AND CONTINGENCIES

    Operating Leases

    The Company has seven non-cancelable operating leases for facilities. The
only significant facility operating leases are for the Company's corporate
headquarters. The original lease is for five and one-half years and commenced in
February 1997. In December 1998, February 1999 and January 2000, the Company
entered into a sub-lease and two lease amendments for additional space at the
facilities with lease terms ending on the same day as the original lease. In
addition to the leases for facilities, the Company leases its telephone system
and certain computer equipment.

    Total rent expense for 1999, 1998 and 1997 was approximately $584,000,
$329,000 and $256,000, respectively.

    Bridge Telerate Royalty Agreement

    The Company has entered into a Software License, Maintenance and Development
Agreement (the "Agreement") with Dow Jones Markets, Inc. (then known as Dow
Jones Telerate, Inc., now known as Telerate, Inc., and a subsidiary of Bridge
Information Systems, Inc.) ("Bridge Telerate"). Under the Agreement, the Company
modified one of its software products to create a Bridge Telerate version and
granted Bridge Telerate a license to promote, market, sublicense and distribute
the Bridge Telerate version for six years. During 1999, 1998 and 1997, the
Company earned approximately $4.0, $3.0 and $2.2 million, respectively, in
royalties (based upon minimum royalty requirements) under the terms of this
Agreement.

    Litigation

    On January 28, 1998, a class action lawsuit, captioned Richard M. Rhodes v.
William R. Cruz; Ralph L. Cruz; Omega Research, Inc.; BancAmerica Robertson
Stephens; Lehman Brothers; and Hambrecht & Quist (Case No. 98-0174-CIV-Lenard),
was filed in the United States District Court for the Southern District of
Florida. On July 1, 1999, pursuant to the stipulation of the parties, the Court
of Appeals for the Eleventh Circuit issued a final order which dismissed with
prejudice all claims against the Company and all other defendants.

    In addition to the above, from time to time the Company may become engaged
in routine litigation incidental to its business. The Company does not believe
that such routine litigation would have a material adverse effect on its
financial position or results of operations.

(13) SEGMENT AND RELATED INFORMATION

    During the three years ended December 31, 1999, management evaluated and
operated the business of the Company as a single segment. The internal financial
reporting systems present data in formats directed to enable management to run
the business as a single operating segment.

    Net revenues from the licensing of the Company's client software products
represented 68%, 78% and 83% of total consolidated net revenues in 1999, 1998
and 1997, respectively. Royalties under the Agreement with Bridge Telerate
represented 17%, 11% and 7% of total consolidated net revenues in 1999, 1998 and
1997, respectively.

(15) RECENT DEVELOPMENTS

    On January 19, 2000, the Company signed a definitive, 100% share-exchange
merger agreement with OnlineTrading.com, a direct access on-line broker.
OnlineTrading.com provides order execution technology that directly accesses
electronic communications networks ("ECN's"), and electronically-centered
exchanges and market makers, in order to provide OnlineTrading.com's customers
with prompt and efficient order execution that avoids traditional market maker
participation and brokerage order-flow arrangements.

    Pursuant to an Agreement and Plan of Merger and Reorganization, as amended
(the "Merger Agreement"), a newly-formed holding company will own 100% of the
issued and outstanding capital stock of Omega Research and OnlineTrading.com.
Upon completion of the merger, as a result of share exchanges between the
holding company and each of Omega Research and OnlineTrading.com, and the
listing of the holding company's shares, the holding company will be the sole
publicly-traded company in the group with its outstanding shares of common stock
listed on The Nasdaq National Market. The holding company will initially be
owned between 62% and approximately 57% (on a fully diluted basis) by Omega
Research's shareholders and between 38% and approximately 43% (on a fully
diluted basis) by OnlineTrading.com's shareholders. The precise percentages will
be determined by the formulae set forth in the Merger Agreement. Closing of the
Merger Agreement is conditioned upon and subject to the filing and effectiveness
of a registration statement on Form S-4, as amended, the approval of the
shareholders of each of Omega Research and OnlineTrading.com, and the
satisfaction of the other conditions precedent to consummating the Merger
Agreement.

     The Company is currently in the process of changing its business model. The
Company has taken certain steps to transform itself from a trading strategy
client software company to an on-line broker that intends to provide to active
traders a best-of-breed, Internet-based trading platform: One that incorporates
and seamlessly integrates powerful trading strategy development tools,
historical and streaming real-time market data and news, and a direct access
electronic order execution system.

     On February 29, 2000, the Company announced that in light of the launch of
WindowOnWallStreet.com, the Company was accelerating its transition to its new
business model by focusing its marketing efforts on WindowOnWallStreet.com (as
opposed to its client software).

10-K and have issued our report thereon dated November 2, 2000. Our audits were
made for the purpose of forming an opinion on the basic financial statements
