                   RATIONAL SOFTWARE CORPORATION
          NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1. BASIS OF PRESENTATION -- The consolidated financial information 
included herein has been prepared without audit in accordance with 
the Company's accounting policies, as described in its latest annual 
report filed with the Securities and Exchange Commission on Form 10-
K. In the opinion of management, all adjustments, which consist only 
of normal recurring adjustments necessary for a fair presentation of 
the Company's financial position, results of operations, and cash 
flows for the interim periods presented have been made.  As 
permitted by Form 10-Q, certain information and footnote disclosures 
normally included in financial statements prepared in accordance 
with generally accepted accounting principles have been condensed or 
omitted.  Operating results for the period ended December 31, 1998 
are not necessarily indicative of the results that may be expected 
for the fiscal year ending March 31, 1999.

2. ACCOUNTS RECEIVABLE - Accounts receivable are presented net of an 
allowance for doubtful accounts of $3,406,000 at December 31, 1998 
and $3,638,000 at March 31, 1998.

3. NET INCOME PER COMMON SHARE - The following table sets forth the 
computation of basic and diluted net income (loss) per share (in 
thousands, except per share amounts):

</TABLE>

4. COMPREHENSIVE INCOME - As of April 1, 1998 the Company adopted 
Statement of Financial Accounting Standards No. 130 (SFAS 130), 
"Reporting Comprehensive Income." SFAS 130 establishes new rules for 
the reporting and display of comprehensive income and its 
components; however, the adoption of this statement had no impact on 
the Company's net income or stockholders' equity. SFAS 130 requires 
unrealized gains or losses on the Company's available-for-sale 
securities and foreign translation adjustments, which have been 
consistently included in stockholders' equity and excluded from net 
income, to be included in comprehensive income.  Prior year 
financial statements have been reclassified to conform to the 
requirements of SFAS 130.

For the three months ended December 31, 1998, total comprehensive 
income amounted to approximately $18,255,000 compared to a 
comprehensive income of $10,188,000 for the same period last year.  
For the nine months ended December 31, 1998, comprehensive income 
amounted to $38,945,000 compared to a comprehensive loss of 
$49,774,000 for the same period last year.

5. RECENT PRONOUNCEMENTS - In June 1997, the Financial Accounting 
Standards Board issued Statement of Financial Accounting Standards 
No. 131 (SFAS 131), "Disclosures about Segments of an Enterprise and 
Related Information." SFAS No. 131 establishes new requirements for 
the reporting of information regarding operating segments, products, 
services, geographic areas and major customers.  The Company will 
provide the disclosures required by SFAS 131 in its Form 10-K for 
the year ended March 31, 1999.

In June 1998, the Financial Accounting Standards Board issued 
Statement No. 133, "Accounting for Derivative Instruments and 
Hedging Activities," which is required to be adopted in years 
beginning after June 15, 1999.  Because of the Company's minimal use 
of derivatives, management does not anticipate that the adoption of 
the new statement will have a significant effect on earnings or the 
financial position of the Company.

6. CONTINGENCIES -  On December 16, 1996, the Company filed  a lawsuit 
against Silicon Graphics, Inc. ("SGI") arising from SGI's failure to 
pay certain royalties due to the Company under a software license 
agreement entered into between the Company's predecessor, Verdix 
Corporation, and SGI.  SGI has filed an answer denying the Company's 
allegations, and also filed a cross-complaint against the Company 
for unspecified damages for alleged wrongdoing arising out of the 
license agreement with SGI.  The Company denies the allegations and 
intends to vigorously defend its position.

On May 28, 1998, a consolidated, amended class action Complaint was 
filed against the Company and Paul D. Levy in the United States 
District Court for the Northern District of California.  That 
action, In re Rational Software Corporation, No. 97-21001 (JF), 
consolidates eight prior-pending, virtually-identical complaints.  
SG Cowen & Company and an SG Cowen & Company analyst are also named 
as defendants.  The complaint alleges that defendants violated 
Sections 10(b) and 20A of the Securities Exchange Act of 1934 and 
California state securities laws through the selective disclosure of 
material inside information regarding the Company's prospects.  The 
complaint seeks unspecified damages on behalf of a class of 
stockholders who purchased the Company's common stock on October 8, 
1997.  Defendants' motions to dismiss the Complaint were granted, 
with leave to amend. The Company anticipates that plaintiffs will 
attempt to amend the Complaint. The Company further expects to file 
a motion to dismiss that amended Complaint.

7. STOCK REPURCHASE - In April, 1998 the board of directors authorized 
the Company to repurchase up to 6,000,000 shares of its common stock 
in the open market to be used for general corporate purposes. The 
Company completed that repurchase program during the September 1998 
quarter.  In October 1998, the board of directors authorized the 
Company to repurchase an additional 6,000,000 shares of its common 
stock in the open market to be used for general corporate purposes. 
Through December 31, 1998 the Company had repurchased a total of 
7,000,000 shares of its common stock, including repurchases 
authorized in April, 1998 and October, 1998, for a total cash outlay 
of approximately $118,147,000.  Repurchases helped offset dilution 
from stock issued under the company's stock option and stock 
purchase plans.

8. RESTRUCTURING COSTS - During the three months ended December 31, 
1998, the Company substantially completed certain elements of the 
organizational integrations following the July 1997 acquisition of 
Pure Atria Corporation (the Pure Atria merger).  This consisted 
primarily of exiting certain non-strategic consulting activities, 
realignment of marketing activities and consolidation of certain 
sales offices.  The current quarter charges related to this 
activity, totaling approximately $3,300,000, were primarily for 
severance costs associated with employee terminations, and charges 
associated with facilities closures.  These charges were offset by a 
reduction of previously accrued facilities expenses related to the 
Pure Atria merger totaling $4,500,000.  The facilities expense 
reduction was due to greater-than-expected recoveries from 
subleasing.  The net impact on the December quarter was a merger and 
integration charge reduction of $1,200,000.

Item 2 -- Management's Discussion and Analysis of Financial Condition 
and Results of Operations


Overview

The statements contained in Management's Discussion and Analysis of 
Financial Condition and Results of Operations, including without 
limitation statements in "Liquidity and Capital Resources at December 
31, 1998", contain "forward looking" information within the meaning of 
Sections 27A of the Securities Act of 1993 and 21E of the Securities 
and Exchange Act of 1934, as amended, and are subject to the safe 
harbor created by those sections.  The actual future results of the 
Company could differ materially from those projected in the forward 
looking information.  For a discussion of certain factors that could 
cause actual results to differ materially from those projected by the 
forward looking information see "Factors That May Affect Future 
Results", at the end of this Item 2.

The Company's revenue is derived from product license fees and charges 
for services, including technical consulting, training, and customer 
support.  In accordance with generally accepted accounting principles, 
the Company recognizes software license revenue upon shipment and 
recognizes customer-support revenue over the term of the maintenance 
agreement.  Revenue from consulting and training is recognized when 
earned.  The Company's license agreements generally do not provide a 
right of return, and reserves are maintained for potential credit 
losses, of which historically there have been only immaterial amounts. 


Comparative Analysis of Operating Results for the Three- and Nine- 
Months Ended December 31, 1998

Total revenue for the three- and nine- month periods ended December 31, 
1998 increased 33% and 28%, respectively, from the comparable prior 
year periods.

Net product revenue for the three- and nine- month periods ended 
December 31, 1998 increased 39% and 32%, respectively, from the 
comparable prior year periods. Consulting and support revenue for both 
the three- and nine- month periods ended December 31, 1998 increased 
23% from the comparable prior year periods.  These increases reflect 
continued strong customer acceptance across the Company's products and 
services.

International revenues from product sales and consulting and customer 
support accounted for 41% and 37%, respectively, of total revenues for 
the three- and nine- month periods ended December 31, 1998, compared to 
34% for both the comparable prior year periods.  The Company's 
international sales are principally priced in local currencies. The 
Company enters into short-term forward currency contracts to hedge 
against the impact of foreign currency exchange rate fluctuations on 
balance sheet exposures denominated in currencies other than the local, 
or "functional" currency of the Company or its subsidiaries.  The total 
amount of these contracts is approximately offset by the underlying 
assets and liabilities denominated in non-functional currencies and 
such contracts are carried at fair market value.  The associated gains 
and losses were not material to the Company's results of operations in 
any period presented.  See Risks Associated with International 
Operations.

Cost of product revenue consists principally of materials, packaging 
and freight, amortization of developed technology and royalties. Cost 
of product revenue for the three- and nine- month periods ended 
December 31, 1998 decreased 9% and increased 13%, respectively, from 
the comparable prior year periods. These costs represented 7% and 9%, 
respectively, of total product revenue for the three- and nine- month 
periods ended December 31, 1998, as compared to 11% and 10%, 
respectively, for the comparable prior year periods.  The decrease in 
product cost as a percentage of product revenue was due primarily to 
better economies of scale on materials and packaging and freight with 
respect to certain products as a result of increased volume.

Cost of consulting and support revenue consists principally of 
personnel costs for training, consulting and customer support. Cost of 
consulting and support for the three- and nine- month periods ended 
December 31, 1998 decreased 7% and 5%, respectively, from the 
comparable prior year periods.  These costs represented 26% and 27%, 
respectively, of total consulting and support revenue for the three- 
and nine- month periods ended December 31, 1998 compared to 34% and 
35%, respectively, for the comparable prior year periods. The decrease 
in cost as a percentage of related revenue is primarily due to changes 
to the Company's customer support business model as a result of 
combining the Pure Atria and Rational service organizations, combined 
with the impact of a relatively fixed support cost base servicing 
increased revenues.

Total expenditures for research and development for the three- and 
nine- month periods ended December 31, 1998 increased 26% and 11%, 
respectively, from the comparable prior year periods.  These costs 
represented 17% and 18%, respectively, of total revenue for the three- 
and nine- month periods ended December 31, 1998 compared to 18% and 
21%, respectively, for the comparable prior year periods. The increase 
in year to year research and development expenses is due primarily to 
additional personnel and related costs to maintain and enhance existing 
products as well as develop new products. 

Sales and marketing expenses for the three- and nine- month periods 
ended December 31, 1998 increased 33% and 18%, respectively, from the 
comparable prior year periods.  These costs represented 42% of total 
revenue for both the three- and nine- month periods ended December 31, 
1998 compared to 41% and 46%, respectively, for the comparable prior 
year periods. The increase in year to year sales and marketing expenses 
reflects additional personnel and related costs to expand Rational's 
sales channels, to penetrate new markets, and to increase its market 
share in core markets.

General and administrative expenses for the three- and nine- month 
periods ended December 31, 1998 increased 21% and 10%, respectively, 
from the comparable prior year periods.  These costs represented 8% of 
total revenue for both the three- and nine- month periods ended 
December 31, 1998 compared to 8% and 10%, respectively, for the 
comparable prior year periods. The increase in year to year general and 
administrative expenses is due primarily to employee related expenses 
associated with the staffing requirements needed to support the 
Company's expanding business.

In the nine-month period ended December 31, 1997 the Company recorded a 
charge of $63,759,000 related to the Pure Atria merger. During the 
three months ended December 31, 1998, the Company substantially 
completed certain elements of the organizational integrations following 
the July 1997 Pure Atria merger.  This consisted primarily of exiting 
certain non-strategic consulting activities, realignment of marketing 
activities and consolidation of certain sales offices.  The current 
quarter charges related to this activity, totaling approximately 
$3,300,000, were primarily for severance costs associated with employee 
terminations, and charges associated with facilities closures.  These 
charges were offset by a reduction of previously accrued facilities 
expenses related to the Pure Atria merger totaling $4,500,000.  The 
facilities expense reduction was due to greater-than-expected 
recoveries from subleasing.  The net impact on the December quarter was 
a merger and integration cost reduction of $1,200,000.  The net cost 
reduction of $1,200,000 is the result of ongoing assessment and 
estimation of costs associated with the prior combinations of Rational 
and other companies.  Such assessment will continue until all related 
costs are incurred or determinable.

Other income, net, consists primarily of interest income, interest 
expense and gains and losses due to fluctuations in foreign currency 
exchange rates. Other income has fluctuated as a result of the amount 
of cash available for investment in interest-bearing instruments and 
from fluctuations in foreign currency exchange rates. Other income, 
net, for the three- and nine- month periods ended December 31, 1998 
decreased $880,000 and $3,832,000, respectively, from the comparable 
prior year periods.  The current year decrease is due primarily to a 
lower average amount of invested cash resulting from repurchase of 
Company common stock in the current periods and to declining interest 
rates.

The provision for income taxes for the three- and nine- month periods 
ended December 31, 1998 is based on the estimated annual effective tax 
rate applied to the profit before income taxes and includes federal, 
state and foreign income taxes. The effective tax rates for fiscal 1999 
and 1998 differ from the federal statutory rate, primarily as a result 
of the recognition of previously unrecognized deferred tax assets, the 
non-deductibility of certain merger related costs, losses in certain 
foreign jurisdictions for which no U.S. benefit was derived, differing 
tax rates in certain foreign jurisdictions and by state taxes.  


Liquidity and Capital Resources at September 30, 1998

As of December 31, 1998, the Company had cash, cash equivalents and 
short-term investments of $221,407,000 and working capital of 
$179,867,000.  Net cash provided by operating activities for the period 
ended December 31, 1998 was composed primarily of net income plus non-
cash charges for depreciation and amortization, tax benefits from stock 
option exercises and an increase in deferred revenue, offset by an 
increase in accounts receivable, a decrease in accrued employee 
benefits and other accrued expenses, accrued merger costs, and accounts 
payable.  Net cash used in investing activities resulted primarily from 
an increase in short-term cash investments and capital expenditures.  
Net cash used in financing activities resulted primarily from the 
repurchase of common stock, offset by issuance of common stock under 
the Employee Stock Purchase Plan and the exercise of employee stock 
options.

In April, 1998 the board of directors authorized the Company to 
repurchase up to 6,000,000 shares of its common stock in the open 
market to be used for general corporate purposes. The Company completed 
that repurchase program during the September 1998 quarter.  In October 
1998, the board of directors authorized the Company to repurchase an 
additional 6,000,000 shares of its common stock in the open market to 
be used for general corporate purposes. Through December 31, 1998 the 
Company had repurchased a total of 7,000,000 shares of its common 
stock, including repurchases authorized in April, 1998 and October, 
1998, for a total cash outlay of approximately $118,147,000.  
Repurchases helped offset dilution from stock issued under the 
company's stock option and stock purchase plans.

The Company believes that expected cash flows from operations combined 
with existing cash and cash equivalents and short-term investments will 
be sufficient to meet its cash requirements for the foreseeable future. 
See also Note 7 to Notes to Condensed Consolidated Financial 
Statements.


Year 2000 Readiness Disclosure

The Company is aware of the problems associated with computer 
systems as the year 2000 approaches. Year 2000 problems are the result 
of common computer programming techniques that result in systems that 
do not function properly when manipulating dates later than December 
31, 1999. The problem may affect internal information technology (IT) 
systems used by the Company for product development, accounting, 
distribution, and planning. The problem may also affect non-IT embedded 
systems such as building security systems, machine controllers, and 
other equipment.

The Company has established a year 2000 project team to develop 
and implement a comprehensive four-phase year 2000 readiness plan for 
its worldwide operations relating to (1) the Company's software 
products, (2) the Company's internal IT and non-IT systems and (3) 
third party customers, vendors and others with whom the Company does 
business. Phase One (Inventory) will consist of identifying all the 
Company's systems, relationships and products that may be impacted by 
year 2000. Phase Two (Assessment) will involve determining the 
Company's current state of year 2000 readiness for those areas 
identified in the inventory phase and prioritizing the areas that need 
to be fixed. Phase Three (Remediation) will consist of developing a 
plan for those areas identified as needing correction in the assessment 
phase.  Phase Four (Implementation) will consist of executing the 
action plan and completing the steps identified to attain year 2000 
readiness.  

With respect to its software products, the Company has completed 
the Inventory, Assessment, Remediation and Implementation phases of the 
plan in the course of developing new products and product upgrades, all 
of which have been designed to be year 2000 compliant. Accordingly, the 
Company does not currently sell or support any products which are not 
year 2000 compliant.  The Company did not separately track the internal 
costs of the research and development efforts related to making its 
products year 2000 compliant, and such costs were principally comprised 
of salaries and benefits of software engineering personnel.  The 
Company funded these research and development costs out of operating 
cash flows.

With respect to its most critical internal IT systems, consisting 
of accounting, data processing and other systems, the Company has 
completed the Inventory, Assessment, Remediation and Implementation 
phases in the course of introducing new systems and system upgrades to 
support the Company's recent rapid growth, including growth through 
acquisitions. No such system implementations were undertaken nor 
accelerated for the sole purpose of becoming year 2000 compliant, and 
it is not practicable to identify any incremental costs related to year 
2000 compliance involved in these system implementations. 

With respect to non-critical IT systems, consisting primarily of 
security systems, fax machines and other miscellaneous systems, and 
non-IT embedded systems, the Company is presently in the Inventory and 
early Assessment phases.  The Company is not yet able to provide 
reasonably accurate estimates of the costs of completing the 
Remediation and Implementation phases with respect to these non-
critical IT and non-IT embedded systems, but the Company presently 
expects to fund all remediation and implementation costs from operating 
cash flows and has not established any specific reserves for these 
costs.  The Company has not yet determined a completion date for 
remediation of all year 2000 systems, but it intends to complete such 
implementation well in advance of January 1, 2000. The Company has not 
yet incurred any material costs specifically related to becoming year 
2000 compliant in its non-critical IT and non-IT embedded systems. As 
with critical IT systems, discussed above, many of the Company's non-
critical IT systems have been replaced or upgraded to accommodate 
expanded business processes due to recent growth and merger activity. 
No such system implementations were undertaken nor accelerated for the 
sole purpose of becoming year 2000 compliant.

The Company is currently early in the inventory phase of 
determining the year 2000 readiness of its significant suppliers, 
subcontractors and customers that do not share information systems with 
the Company, and is preparing to query such third-parties about their 
year 2000 readiness.   The Company has no means of ensuring that these 
third parties will be year 2000 ready.

Based on information currently available to the Company, the 
Company believes that the most reasonably likely worst case year 2000 
scenarios with respect to the Company relate to the potential failure 
of third party suppliers, subcontractors and customers to become year 
2000 compliant and, to a lesser extent, the Company's potential failure 
to reach year 2000 compliance with respect to non-critical IT and non-
IT embedded systems.  The inability of suppliers, subcontractors and 
customers to complete their year 2000 remediation processes in a timely 
fashion could result in delays in introducing new products, reduced 
sales of new or existing products and disruptions in strategic 
relationships, which could in turn have a material and adverse effect 
on the Company's results of operations and financial condition.  The 
effect of non-compliance by suppliers, subcontractors and customers is 
not reasonably quantifiable.

While the Company expects to the attain year 2000 readiness with 
respect to non-critical IT and non-IT embedded systems, there is no 
assurance that the Company will be successful in its efforts to 
identify and address all year 2000 system issues on time.  Failure to 
do so may adversely impact the Company's results of operations or 
adversely affect the Company's relationships with customers, vendors or 
others. For example, failure to achieve year 2000 readiness could delay 
the Company's ability to produce and ship products, invoice customers 
and collect payments, and could disrupt customer service, technical 
support and facilities. The Company could suffer increased costs, lost 
sales or other negative consequences resulting from customer 
dissatisfaction, including litigation.  Failures of security systems 
relying on non-IT embedded systems could compromise the Company's 
operations or ability to safeguard proprietary information.  

The Company does not currently have any year 2000 related 
contingency plans. The Company may institute contingency planning at 
the completion of the Assessment phase of its year 2000 readiness plan 
with respect to non-critical IT and non-IT embedded systems.

The above discussion regarding costs, risks and estimated completion 
dates for the year 2000 is based on the Company's best estimates given 
information that is currently available, and is subject to change. 
There can be no assurance that actual costs will not substantially 
exceed the Company's assessment due to internal year 2000 problems or 
year 2000 problems associated with the Company's IT and non-IT systems 
and products.  In addition, while the Company believes it has achieved 
year 2000 compliance with respect to its software products and  
critical IT systems, there could be unanticipated year 2000 related 
failures in such products or systems that could have a material and 
averse effect on the Company's results of operations and financial 
condition.  Further, there can be no guarantee that the systems of 
other companies on which the Company's systems rely will be remediated 
in a timely manner, or that a failure to remediate by another company, 
including without limitation any of the Company's vendors, customers, 
or partners, or a remediation that is incompatible with the Company's 
systems would not have a material adverse effect on the Company.










Factors That May Affect Future Results


Risks Associated with Recent and Future Acquisitions

Rational acquired Pure Atria Corporation (Pure Atria) on July 30, 
1997, with the expectation that the acquisition would result in long-
term strategic benefits. The realization of these anticipated benefits 
will continue to depend in part on integration of the companies' 
respective product offerings and research and development efforts. 
There can be no assurance that this will occur. Successful integration 
of the companies' respective sales forces will continue to require 
sales personnel to become familiar with the sales cycles and sales 
approaches required for products recently added to their portfolios, 
and any failure to do so may result in sales delays and decreased 
revenues for the Company. It is possible that the continued integration 
of the companies' respective products and the creation of integrated 
bundles and suites may not be accomplished in a timely manner or may 
prove to be technologically infeasible. The difficulties of integrating 
the two companies' respective operations is compounded by the fact that 
each company had significant operations on both the East Coast and the 
West Coast of the United States and in a number of other countries. The 
acquisition of Pure Atria has been accounted for as a pooling of 
interests.  Accordingly, if such accounting treatment were to be 
nullified for any reason, it would materially and adversely affect 
Rational's reported earnings and, potentially, its stock price. 

In addition to the acquisition of Pure Atria, during approximately the 
past four years, Rational has made a number of strategic acquisitions, 
including SQA, Inc., Performance Awareness Corporation, Requisite, 
Inc., Softlab AB, and Software 9000 in the quarter ended March 31, 
1997, the Visual Test product from Microsoft in October 1996, and other 
acquisitions in earlier periods. Rational has recently acquired 19.9% 
of the outstanding capital stock of ObjecTime, Ltd. Acquisitions result 
in the diversion of management's attention from day-to-day operations 
and include numerous other risks, including difficulties in the 
integration of operations, products, and personnel. To the extent that 
acquisitions have in the past resulted, or may in the future result, in 
a diversion of resources or that efforts to integrate recent and future 
acquisitions fail, there could be a material adverse effect on 
Rational's business, results of operations, and financial condition. 
Acquisitions have the potential to result in dilutive issuances of 
equity securities, the incurrence of debt, and amortization expenses 
related to goodwill and other intangible assets. Rational's management 
has historically evaluated on an ongoing basis the strategic 
opportunities available to the Company. Rational may in the near-term 
or long-term future pursue acquisitions of complementary products, 
technologies, or businesses.


Fluctuations in Operating Results

Revenue in any quarter is substantially dependent on orders 
booked and shipped in that quarter. Because staffing and operating 
expenses are based on anticipated revenue levels and a high percentage 
of the costs are fixed, small variations in the timing of the 
recognition of specific revenues could cause significant variations in 
operating results from quarter to quarter. Historically, the Company 
has earned a substantial portion of its revenues in the last weeks of 
the quarter. To the extent these trends continue, the failure to 
achieve such revenues in the last weeks of any given quarter will have 
a material adverse effect on the Company's financial results for that 
quarter. The Company's revenue is difficult to forecast because 
Rational's  sales cycles, from initial evaluation to purchase, vary 
substantially from customer to customer and from product to product and 
because the markets for Rational's products are rapidly evolving. In 
addition, the Company's results will be affected by the number, timing, 
and significance of new product announcements by it and its 
competitors, its ability to develop, introduce, and market new, 
enhanced, and integrated versions of its products on a timely basis, 
the level of product and price competition, changes in operating 
expenses, changes in average selling prices and product mix, any 
changes in its sales incentive strategy, the experience level of and 
any changes in sales personnel, any changes in sales cycles, the mix of 
direct and indirect sales, product returns, and general economic 
factors, among others. The Company's sales will also be sensitive to 
existing and prospective customers' budgeting practices and global 
economic conditions.

        Unanticipated expenses associated with the integration of 
Rational and Pure Atria may arise, or the Company may incur additional 
material charges in subsequent quarters to reflect additional costs 
associated with the integration of the two companies. Total costs 
associated with such transactions resulted in an operating loss and a 
net loss for the Company's fiscal year ended March 31, 1998, and could 
negatively impact financial results in future periods for the reasons 
discussed above.

Although Rational has experienced growth in revenues in recent 
years, there can be no assurance that, in the future, Rational will 
sustain revenue growth or be profitable on a quarterly or annual basis. 
Further, the revenues and operating income (exclusive of nonrecurring 
operating, restructuring, and merger-related expenses) experienced by 
Rational in recent quarters are not necessarily indicative of future 
results, and period-to-period comparisons of Rational's financial 
results should not be relied on as an indication of future performance. 
Fluctuations in operating results have previously and may continue to 
result in volatility in the price of Rational's common stock.

Due to all of the foregoing factors, it is possible that in some future 
quarter, Rational's operating results will be below the expectations of 
public market analysts and investors. In such event, the price of 
Rational's common stock would likely be materially adversely affected, 
and significant declines in stock prices frequently result in costly 
and lengthy securities litigation, with its attendant costs, 
distraction, and liability exposure.


Volatility of Stock Price

The market price of the Company's common stock has been, and is 
likely to continue to be, volatile. Factors such as new product 
announcements or changes in product pricing policies by the Company or 
its competitors, quarterly fluctuations in the Company's operating 
results, announcements of technical innovations, announcements relating 
to strategic relationships or acquisitions, changes in earnings 
estimates by analysts, and general conditions in the software-
development market, among other factors, may have a significant impact 
on the market price of the Company's common stock. Should the Company 
fail to introduce products on the schedule expected, the Company's 
stock price could be adversely affected.

Any shortfall in anticipated operating results could have an 
immediate and significant adverse effect on the market price of the 
Company's common stock. Further, the Company incurred substantial 
merger-related charges in the quarter ended September 30, 1997. 
Although Rational entered into the merger with the expectation that it 
would be accretive in the long term, the merger has been dilutive in 
the initial periods following its effective time, and there can be no 
assurance as to when the merger will become accretive, if ever. Any 
failure of the Pure Atria merger to meet expectations as to potential 
business synergies or any failure of the Pure Atria merger to be 
accretive in any quarter could have an immediate and significant 
adverse effect on the market price of the Company's common stock.

Statements or changes in opinions, ratings, or earnings estimates 
made by brokerage firms or industry analysts relating to the market for 
software and high-technology company stocks or relating to Rational 
specifically have resulted, and could in the future result, in an 
immediate and adverse effect on the market price of Rational's common 
stock. Statements by financial or industry analysts regarding the 
extent of the dilution in Rational's net income per share resulting 
from operating results, the Pure Atria merger, or other developments 
and the extent to which such analysts expect potential business 
synergies to offset such dilution can be expected to contribute to 
volatility in the market price of Rational's common stock. In addition, 
in recent years the stock market in general, and the shares of 
technology companies in particular, have experienced extreme price 
fluctuations. This volatility has had a substantial effect on the 
market prices of securities issued by many companies, including 
Rational, in certain cases for reasons unrelated to the operating 
performance of the specific companies. These broad market fluctuations 
may adversely affect the market price of Rational's common stock. 


Dependence on Market Growth for Sophisticated Development Tools

Rational's future growth and financial performance will depend in 
part on broad acceptance of off-the-shelf products that address 
critical elements of the software development process including 
requirements management, modeling, testing, and configuration and 
change management. Sales of such products may not continue to grow, or 
the Company may be unable to respond effectively to evolving customer 
requirements. The number of software developers using Rational's 
products is relatively small compared to the number of developers using 
more traditional technology and products, or manual approaches. The 
adoption of the Company's products by software developers who have 
traditionally used other technology requires reorientation to 
significantly different approaches to development. Customers may rely 
on internally-developed tools instead of off-the-shelf products, or 
customers may rely on manual approaches instead of automated tools that 
require up-front capital investment. The acceptance of the Company's 
products, therefore, may not expand beyond sophisticated software 
developers who are early adopters of the technology. Furthermore, 
potential customers may be unwilling to make the investment required to 
retrain software developers to build software using the Company's 
products rather than traditional techniques. Many of Rational's 
customers have purchased only small quantities of the Company's 
products, and these or new customers may decide not to broadly 
implement or purchase additional units of such products.


Dependence on Acceptance of Industry Standards

Rational's future growth and financial performance may depend on 
the development of industry standards that facilitate the adoption of 
component-based development, as well as Rational's ability to play a 
leading role in the establishment of those standards. The Company has 
developed the Unified Modeling Language (UML) for visual modeling, 
which has been adopted by the Object Management Group (OMG), an 
industry consortium, for inclusion in their object analysis and design 
facility specification. The official sanction in the future of a 
competing standard by the OMG or the promulgation of a competing 
standard by one or more major platform vendors could have a material 
adverse effect on Rational's marketing and sales efforts and, in turn, 
on Rational's business, operating results, and financial condition.


Expansion of Product Lines; Dependence on New Product Introductions

The Company believes that its continued success will depend in 
part on its ability to provide a tightly integrated line of software 
application-development tools, as well as integrated product suites and 
bundles, that support software development for a number of 
implementation languages. This will require the Company to modify and 
enhance its current products and to continue to develop, introduce, and 
integrate new products. The Company believes its continued success will 
become increasingly dependent on its ability to support both the 
Microsoft platform (including the Windows 95, Windows 98, and Windows 
NT operating systems) and the IBM platform. The Company also believes 
its continued success will become increasingly dependent on its ability 
to support Web-based development of business-critical applications 
using latest technologies. The Company believes that it will be 
particularly important to successfully develop and market a broader 
line of products for C++, Visual Basic, Java, and other implementation 
languages in order to be successful in its efforts to broaden its 
customer base and to further increase its share in its existing market 
segments. The Company also believes that, over time, its products must 
be extended to continually support the rapidly changing standards and 
technologies used in the development of web-based applications, as well 
as off-the-shelf products from companies such as SAP, The Baan Company, 
and PeopleSoft. The Company may be unable to successfully develop and 
market such a broad line of products or may encounter unexpected 
difficulties and delays in integrating new products with existing 
product lines.

Rational has plans to introduce new products and enhanced 
versions of current products during the next few fiscal quarters. Delay 
in the start of shipment of new, enhanced, or integrated products, 
suites, and bundles would have an adverse effect on the Company's 
revenues, gross profit, and operating income. As a result of Rational's 
business alliance with Microsoft, certain of Rational's new product 
releases are expected to be tightly integrated with new releases of 
certain Microsoft products. To the extent that scheduled Microsoft 
product releases are delayed, there could be a material adverse effect 
on Rational's revenues from new products. 

Rational attempts to make adequate allowances in its product 
release schedules for both internal and beta-site testing of product 
performance. Because of the complexity of the Company's products, 
however, the release of new products may be postponed should test 
results indicate the need for redesign and retesting or should the 
Company elect to add product enhancements in response to beta customer 
feedback.


Competition

The industry for tools for automating software application 
development and management is extremely competitive and rapidly 
changing. Rational expects to continue to experience significant and 
increasing levels of competition in the future. Rational believes that 
the major competitive factors in its markets include corporate and 
product reputation, innovation with frequent product enhancement, 
breadth of integrated product line, the availability of integrated 
suites and bundles, product architecture, functionality and features, 
product quality, performance, ease of use, support, availability of 
technical consulting services, and price. Rational faces intense 
competition for each product within its product lines, generally from 
both Windows, Windows NT, and UNIX vendors. Because individual product 
sales are often the first step in a broader customer relationship, 
Rational's success will depend in part on its ability to successfully 
compete with numerous competitors at each point in its product line.

Rational faces competition from software-development tools and 
processes developed internally by customers, including ad hoc 
integrations of numerous standalone development tools. Customers may be 
reluctant to purchase products offered by independent vendors such as 
the Company. As a result, the Company must educate prospective 
customers about the advantages of the Company's products versus 
internally developed software-quality systems.

Rational faces competition from, among others, Micro Focus Group, 
plc, Platinum Technology, Inc., Select Software Tools plc, Cayenne, 
Oracle, IBM Corporation (IBM), Sun Microsystems, and Sybase Inc., as 
well as numerous privately held tool suppliers offering traditional 
CASE tools that compete with the Rational Rose approach to visual 
modeling and component-based development. Rational's RequisitePro 
requirements-management product faces competition from companies such 
as GEC-Marconi. Rational's software-testing tools-Purify, Quantify, 
PureCoverage, SQA Suite, Rational Visual Test, Performance Studio, 
Rational DevelopmentDesktop and preVue--face competition from 
Compuware, Mercury Interactive Corporation, Segue Software, Inc., Micro 
Focus Group, plc, Inc., Computer Associates, Platinum Technologies, 
Terodyne, Cyrano, SQL Bench International, Inc., and several private 
companies offering testing-automation tools. Microsoft, Compuware, 
Oracle, Sybase, and several of the major UNIX platform vendors, 
including Sun Microsystems, Hewlett Packard, Digital Equipment 
Corporation (recently acquired by Compaq Computer Corporation), Silicon 
Graphics, Inc., and IBM, also compete with Rational with respect to 
software-quality products and testing tools, with testing products 
customized to certain of their other software products. Rational Apex 
for C/C++ faces competition from, among others, major UNIX platform 
vendors such as Sun Microsystems, Hewlett-Packard, and Digital 
Equipment Corporation, which have C/C++ compilers and debuggers and, in 
some cases, programming environments for their platforms. In addition, 
numerous privately held companies offer compilers, debuggers, and 
programming environments that compete with Rational Apex. Rational's 
ClearCase, ClearDDTS, and ClearQuest product line faces competition 
from various suppliers offering products with configuration and change 
management functions, including Continuus Software Corporation, 
StarBase Corporation, Hewlett Packard, True Software, SQL Software, 
ltd., Micro Focus Group, plc, Sun Microsystems, Platinum Technologies, 
Mortice Kern Systems (MKS) Inc., and IBM. The Rational Apex Ada product 
line faces competition from Aonix, Green Hills Software, Inc., and a 
large number of other suppliers offering Ada products for native and 
embedded systems.

The Company also experiences competition with respect to a number 
of its products, both from utilities commonly bundled with versions of 
operating systems and from standalone product offerings. For example, 
versions of UNIX are commonly bundled with utilities (such as SCCS and 
RCS) that provide version control, which is part of the functionality 
provided by ClearCase. Some system vendors, such as Sun, already have 
products, such as Workshop, that provide features similar to those in 
Purify or others of the Company's products and would compete directly 
with such products if offered on a standalone basis. The Company's 
ClearQuest defect-tracking product competes with products from LBMS, 
Inc., which was acquired by Platinum Technology, Inc. There can be no 
assurance that Sun, which has a license to some of the Company's 
patents, will not introduce standalone products that compete with the 
Company's products. Companies offering products competitive with 
Rational Summit and ClearCase in the UNIX marketplace include Sun, 
which offers TeamWare, IBM, which offers Configuration 
Management/Version Control (CMVC), Computer Associates (CA), which 
offers the Endeavor WSX product, and Platinum through its acquisition 
of Softool Corp., which markets CCC Harvest. In addition, there are 
several smaller, privately held companies that market competitive 
products, including Continuus Software Corporation, which markets 
Continuus/CM. Other companies have offered version control or 
configuration management products outside the UNIX market. Companies in 
this category include CA, Micro Focus Group, plc, and Microsoft. CA has 
a large installed base of its configuration management product on IBM 
mainframes. Micro Focus has a large installed base of DOS and Windows 
software developers. In 1994, Microsoft acquired OneTree Software, 
which offers a version control product. The Company expects additional 
competition from other established and emerging companies. 

Rational believes that the increased level of competition it 
observed in fiscal 1998 and the first three quarters of fiscal 1999 
will continue to increase. Certain of Rational's competitors are more 
experienced than Rational in the development of software-engineering 
tools, databases, or software-development products. Some of Rational's 
competitors have, and new competitors may have, larger technical 
staffs, more established distribution channels, and greater financial 
resources than Rational. There can be no assurance that either existing 
or new competitors will not develop products that are superior to 
Rational's products or that achieve greater market acceptance. 
Rational's future success will depend in large part on its ability to 
increase its share of its target markets and to license additional 
products and product enhancements to existing customers. Future 
competition may result in price reductions, reduced margins, or loss of 
sales, which in turn would have a material adverse effect on the 
Company's business, results of operations, and financial condition.


Dependence on Sales Force and Other Channels of Distribution

Rational currently distributes its products primarily through field 
sales personnel teamed with highly trained technical-support personnel. 
Rational believes that a high level of technical consulting, training, 
and customer support is essential to maintaining its competitive 
position and has found that the ability to deliver a high level of 
technical consulting, training, and customer support is an important 
selling point with respect to its products. Although complementary to 
Rational's products, the services provided by these personnel have 
historically yielded lower margins for Rational than the Company's 
product business. If these services constitute a higher proportion of 
total revenues in the future, the Company's margins will be adversely 
affected. Rational markets and sells its products and services directly 
through its major-accounts field operations, its telesales 
organizations, and its World Wide Web site, and indirectly through 
channels such as VARs and distributors. There can be no assurance that 
such channels will be successful in increasing sales of the Company's 
products or in reducing its sales costs on a percentage basis.


Dependence on Key Personnel

Rational believes that the hiring and retaining of qualified 
individuals at all levels in the Company  will be essential to the 
Company's ability to manage  growth successfully, and there can be no 
assurance that the Company will be successful in attracting and 
retaining the necessary personnel. The Company will be particularly 
dependent on the efforts and abilities of its senior management 
personnel. The departure of any of the senior management members or 
other key personnel of the Company could have a material adverse effect 
on the Company's business, financial condition, or results of 
operations, depending on the timing of the departure, changes in the 
Company's business prior to such time, the availability of qualified 
personnel to replace them, and whether such personnel depart singly, 
contemporaneously, or as a group, among other factors. Merger 
activities, such as the acquisition of Pure Atria, can be accompanied 
or followed by the departure of key personnel, which can compound the 
difficulty of integrating the operations of the parties to the business 
combination. 

The ability of the Company to attract and retain the highly 
trained technical personnel that are integral to its direct sales and 
product development teams may limit the rate at which the Company can 
develop products and generate sales. Competition for qualified 
personnel in the software industry is intense, and there can be no 
assurance that the Company will be successful in attracting and 
retaining such personnel. Merger activities, such as the acquisition of 
Pure Atria, may have a destabilizing effect on employee retention at 
all levels within the Company. Departures of existing personnel, 
particularly in key technical, sales, marketing, or management 
positions, can be disruptive and can result in departures of other 
existing personnel, which in turn could have a material adverse effect 
on the Company's business, operating results, and financial condition.

A traditional means of retaining employees following declines in 
a corporation's stock price, such as those experienced recently by 
Rational, is to reprice "underwater" stock options, both to offer an 
equity incentive to existing employees and to avoid inequities relative 
to new employees offered lower-priced options. On November 4, 1997, the 
Company's board of directors approved a program enabling the Company to 
reprice stock options for most employees. The repriced options are 
subject to additional lock-up and repurchase restrictions. Members of 
the Company's senior management team at that time were not eligible to 
participate in that repricing program. In April 1998, the compensation 
committee of the board, after consulting with all of the outside 
directors, approved repricing agreements with the members of the senior 
management team who were not eligible to participate in the November 
1997 repricing program. The senior officer repricing was completed on 
substantially the same terms, including the disposition limitations and 
repurchase provisions, offered to the rest of the employees in November 
1997, although at the higher market price existing at the time of the 
April 1998 repricing. There can be no assurance that such repricing 
will be sufficient to retain employees or senior management or that at 
some future date the outstanding stock options will not again be 
underwater. To the extent that options held by employees, including 
members of senior management, again become underwater, those options 
may not serve as an incentive to retain these individuals. The 
departure of one or more members of the senior management team could 
have a material adverse effect on the Company's business, results of 
operations, and financial condition.


Rapid Technological Change

The industry for tools for automating software application 
development and management is characterized by rapid technological 
advances, changes in customer requirements, and frequent new product 
introductions and enhancements. The introduction of products embodying 
new technologies and the emergence of new industry standards and 
practices can render existing products obsolete and unmarketable. The 
Company must respond rapidly to developments related to Internet and 
intranet applications, hardware platforms, operating systems, and 
applicable programming languages. Such developments will require the 
Company to make substantial product-development investments. Any 
failure by the Company to anticipate or respond adequately to 
technology developments and customer requirements, or any significant 
delays in product development, introduction, or integration, could 
result in a loss of competitiveness or revenue. To the extent the 
Company does not respond to technological change or evolving customer 
requirements with new products or product enhancements, such new 
products or product enhancements may fail to achieve market acceptance.

In addition, rapid growth of, interest in, and use of Internet 
and intranet environments is a recent and emerging phenomenon. The 
Company's success may depend, in part, on the compatibility of its 
products with Internet and intranet applications. The Company may fail 
to effectively adapt its products for use in Internet or intranet 
environments or to produce competitive Internet and intranet 
applications.

Rational believes that factors affecting the ability of its 
products to achieve broad consumer acceptance include product 
performance, price, ease of adoption, displacement of existing 
approaches, and adaptation to rapid technological change and 
competitive product offerings. The Company may be unable to respond 
promptly and effectively to the challenges of technological change and 
its competitors' innovations, and it is possible that the Company will 
be unable to achieve the necessary market acceptance or compete 
effectively in new markets.


Dependence on Strategic Relationships

Rational's development, marketing, and distribution strategies 
rely increasingly on its ability to form long-term strategic 
relationships with major software and hardware vendors, many of whom 
are substantially larger than Rational. These business relationships 
often consist of cooperative marketing programs, joint customer 
seminars, lead referrals, or joint development projects. Although 
certain aspects of some of these relationships are contractual in 
nature, many important aspects of these relationships depend on the 
continued cooperation of each party with Rational. Merger activity, 
such as the acquisition of Pure Atria, may disrupt these relationships 
or activities, and certain partners may reassess the value of their 
relationship with Rational as a result of such merger activity. 
Divergence in strategy between Rational and any given partner, a change 
in focus by any given partner, or competitive product offerings 
introduced by any given partner may interfere with Rational's ability 
to develop, market, sell, or support its products, which in turn would 
have a material adverse effect on Rational's business, results of 
operations, and financial condition. See "Business Alliance with 
Microsoft."


Business Alliance with Microsoft

On October 2, 1996, Rational and Microsoft announced the formation of a 
business alliance that consisted of Rational's acquisition of 
Microsoft's Visual Test product, technology cross-licensing, joint 
development projects, and joint marketing programs. Although Rational 
believes that Microsoft's current strategy in relation to the 
enterprise information systems market is based on component-based 
development, there can be no assurance that this strategy will continue 
or that, if it does continue, Microsoft's emphasis or priorities will 
not change in the future, resulting in less attention and fewer 
resources being devoted to Microsoft's relationship with Rational. 
Although certain aspects of the business alliance are contractual in 
nature, many important aspects of the relationship depend on the 
continued cooperation of the two companies, and there can be no 
assurance that Rational and Microsoft will be able to work together 
successfully over an extended period of time. In addition, there can be 
no assurance that Microsoft will not use the information it gains in 
its relationship with Rational to develop or market competing products.


Acquisition of the Visual Test Product

The Company acquired the Visual Test product from Microsoft on 
October 2, 1996. There can be no assurance that Rational will be able 
to successfully incorporate the Visual Test product into its integrated 
family of products or that it will be able to achieve significant sales 
of the Visual Test product. Many potential customers for Visual Test 
differ from the Company's historical customer base in terms of 
component-based software-development expertise, purchasing processes, 
financial resources, and expectations regarding software-engineering 
tools. There can be no assurance that the Company will not encounter 
unanticipated concerns of Visual Test customers that are different from 
the concerns of the Company's traditional customers or that the Company 
will have the infrastructure and experience necessary to adequately 
respond to the volume and type of such concerns.

Rational has granted Microsoft a nonexclusive, perpetual license 
to the Visual Test product source code for the purpose of creating 
derivative works and for the purpose of distributing portions of the 
Visual Test product and derivative works as part of Microsoft products 
that do not directly compete with the Visual Test product in the 
software-testing tools area. There can be no assurance that Microsoft 
will not use such rights to create and distribute products that compete 
with other Rational products. Rational has also granted Microsoft a 
five-year option to obtain a license to incorporate certain elements of 
Visual Test technology into Microsoft development tool products, 
including Visual Basic, Visual C++, and Visual J++. Should Microsoft 
exercise such right, sales of the Visual Test product by Rational could 
be materially and adversely impacted. See "Fluctuations in Operating 
Results."


Licensing of Rational Rose Technology to Microsoft

In October 1996, Microsoft and Rational entered into an agreement 
providing for the inclusion of a subset of the Rational Rose visual 
modeling technology in future versions of Microsoft's enterprise-
oriented visual tools. The Company's objective in entering into this 
arrangement is to expose the Company's technology to a broader customer 
base and not to generate direct product revenue from Microsoft. The 
Company expects that continued changes in the Company's pricing models 
and combinations of features within product lines will be required to 
appeal to this customer base, and there can be no assurance that such 
changes will achieve customer acceptance. The licensing of Rational's 
Rose technology to Microsoft has not resulted and the Company does not 
expect it to result in a material increase in product revenue. In 
addition, there can be no assurance that developers introduced to the 
Rational Rose technology incorporated into Microsoft products will 
become purchasers of Rational products in the future. Rational has 
granted Microsoft the option to obtain a perpetual, nonexclusive right 
to source code for certain aspects of the Rational Rose technology 
after the termination of the agreement. While Rational believes that 
Microsoft's and Rational's strategies currently are complementary, 
there can be no assurance that Microsoft will not use this right to 
develop and market competing products in the future.


Dependence on Major Operating Systems

Many of Rational's major products have historically been licensed 
for use principally on certain versions of the UNIX platform. These 
products constitute a substantial portion of Rational's product and 
service revenues. Any factors adversely affecting the demand for, or 
use of, the UNIX operating system that would require changes to 
Rational's products would have a material adverse effect on the 
business, operating results, and financial condition of Rational. 
Likewise, others of Rational's major products have historically been 
licensed for use purely on the Windows or Windows NT operating systems. 
These products also constitute a substantial portion of Rational's 
product and service revenues. Any factors adversely affecting the 
demand for, or use of, the Windows or Windows NT operating systems that 
would require changes to Rational's products would have a material 
adverse effect on the business, operating results, and financial 
condition of Rational. In addition, any changes to the underlying 
components of or interfaces to the UNIX, Windows or Windows NT 
operating systems that would require changes to Rational's products for 
those platforms would materially and adversely affect Rational if it 
were not able to successfully develop or implement such changes in a 
timely fashion.


Adverse Impact of Promotional Product Versions on Actual Product Sales

The Company's marketing strategy relies in part on making 
elements of its technology available for no charge or at a very low 
price, either directly or by incorporating such elements into products 
offered by the Company's partners, such as Microsoft. This strategy is 
designed to expose the Company's products to a broader customer base 
than its historical customer base and to encourage potential customers 
to purchase an upgrade or other higher-priced product from the Company. 
There can be no assurance that the Company will be able to introduce 
enhancements to its full-price products or versions of its products 
with intermediate functionality at a rate necessary to adequately 
differentiate them from the promotional versions, particularly in cases 
where the Company's partners are distributing versions of the Company's 
products with other desirable features.


Management of Growth

Rational has experienced rapid growth, particularly as a result 
of its acquisitions, and the Company is experiencing a period of 
aggressive product introductions that have placed, and may continue to 
place, a significant strain on its financial, operational, management, 
marketing, and sales systems and resources, including its personnel. 
Projects such as the expansion of or enhancements to product lines, 
efforts to address broader markets and to expand distribution channels, 
numerous acquisitions as described in "Risks Associated with Recent and 
Future Acquisitions" and business alliances such as the  arrangement 
between Rational and Microsoft, when added to the day-to-day activities 
of Rational, have placed and will continue to place further strain on 
management resources and personnel. If Rational's management is unable 
to effectively manage growth, its business, competitive position, 
results of operations, and financial condition will be materially and 
adversely affected.

To achieve and manage continued growth, the Company must continue 
to expand and upgrade its information-technology infrastructure and its 
scalability, including improvements to various operations, financial, 
and management information systems. In addition, the Company believes 
that to remain competitive it must significantly expand its 
capabilities for electronic commerce. Improving management systems and 
infrastructure and building electronic commerce capabilities will 
require that the Company recruit and retain highly qualified technical 
personnel, and such personnel resources are extremely scarce in the 
areas where the Company operates. Failure to improve management 
infrastructure and build electronic commerce capabilities for future 
growth would materially and adversely affect the Company's business, 
competitive position, results of operations, and financial condition. 
See "Dependence on Key Personnel."


Risk of Software Defects

Software products as complex as those sold by the Company often 
contain undetected errors, or "bugs," or performance problems. Such 
defects are most frequently found during the period immediately 
following the introduction of new products or enhancements to existing 
products. Despite extensive product testing prior to introduction, the 
Company's products have in the past contained software errors that were 
discovered after commercial introduction. Errors or performance 
problems may also be discovered in the future. Any future software 
defects discovered after shipment of the Company's products could 
result in loss of revenues or delays in market acceptance, which could 
have a material adverse effect on the Company's business, operating 
results, or financial condition. Further, because the Company relies on 
its own products in connection with the development of its software, 
any such errors could make it more difficult to sell such products in 
the future. Rational attempts to make adequate allowance in its new- 
product release schedule for both internal and beta-site testing of 
product performance. Because of the complexity of the Company's 
products, however, the release of new products by the Company may be 
postponed should test results indicate the need for redesign and 
retesting or should the Company elect to add product enhancements in 
response to beta customer feedback.


Risks Associated with International Operations

International sales accounted for approximately 34%, 27% and 27% 
of Rational's revenues in fiscal 1998, 1997, and 1996, respectively and 
represented 37% for the nine months ended December 31, 1998. Rational 
expects that international sales will continue to account for a 
significant portion of the Company's revenues in future periods. 
International sales are subject to inherent risks, including unexpected 
changes in regulatory requirements and tariffs, unexpected changes in 
global economic conditions, difficulties in staffing and managing 
foreign operations, longer payment cycles, greater difficulty in 
accounts receivable collection, potentially adverse tax consequences, 
price controls or other restrictions on foreign currency, difficulties 
in obtaining export and import licenses, costs of localizing products 
for foreign markets, lack of acceptance of localized products in 
international markets, and the effects of high local wage scales and 
other expenses. Any material adverse effect on the Company's 
international business would be likely to materially and adversely 
affect the Company's business, operating results, and financial 
condition as a whole. 

Rational's international sales are generally transacted through 
its international sales subsidiaries.  The revenue generated by these 
foreign subsidiaries, as well as their local expenses, are generally 
denominated in local currencies. Accordingly, the functional currency 
of each international sales subsidiary is the local currency.  Rational 
has engaged in limited hedging activities to protect it against losses 
arising from remeasuring assets and liabilities denominated in 
currencies other than the functional currency of the related 
subsidiary. The Company is also exposed to foreign exchange rate 
fluctuations as the financial results of international subsidiaries are 
translated into U.S. Dollars in consolidation.  As exchange rates vary, 
these results, when translated, may vary from expectations and 
adversely impact overall expected profitability.  The Company currently 
does not hedge against this exposure. There can be no assurance that 
the Company will not experience a material adverse impact on its 
financial condition and results of operations from fluctuations in 
foreign currencies or from further economic problems in Asia in the 
future.  


Risks Associated with Asian Economic Crises

In addition to general risks associated with international 
operations listed above, there are additional risks associated with the 
continuing economic crisis in Asia.  Many of Rational's customers, who 
are based in either Europe or the Americas, do a substantial amount of 
business in Asia.  As economic conditions have affected buying behavior 
in Asia, Rational's customers may also be affected, resulting in 
changes to their own buying behavior in Europe and the Americas. The 
Company has experienced no significant adverse impact on revenues or 
operating results as a result of changes in exchange rates or current 
economic conditions in many Asian countries.  There can be no assurance 
that the Company will not experience a material adverse impact on its 
financial condition and results of operations from the impact of the 
Asian economic crisis both in Asia and in other geographies.


European Monetary Conversion

        In January 1999, the new "Euro" currency was introduced in 
certain European countries that are part of the European Monetary Union 
("EMU"). During 2002, all EMU countries are expected to be operating 
with the Euro as their single currency. A significant amount of 
uncertainty exists as to the effect the Euro will have on the 
marketplace generally and, additionally, all of the final rules and 
regulations have not yet been defined and finalized by the European 
Commission with regard to the Euro currency.  We are currently 
assessing the effect the introduction of the Euro will have on our 
internal accounting systems and the sales of our products. We are not 
aware of any material operational issues or costs associated with 
preparing our internal systems for the Euro. However, we do utilize 
third party vendor equipment and software products that may or may not 
be EMU compliant. Although we are currently taking steps to address the 
impact, if any, of EMU compliance for such third party products, the 
failure of any critical components to operate properly post-Euro may 
have an adverse effect on the business or results of operations of our 
Company or require us to incur expenses to remedy such problems.


Limited Protection of Intellectual Property and Proprietary Rights

Rational relies on a combination of copyright, trademark, and 
trade-secret laws, employee and third-party nondisclosure agreements, 
and other methods to protect its proprietary rights. Despite these 
precautions, it may be possible for unauthorized third parties to copy 
certain portions of the Company's products or reverse engineer or 
obtain and use information that Rational regards as proprietary. 
Rational generally licenses its software products to end-users on a 
right-to-use basis pursuant to a perpetual license. Rational licenses 
its products primarily under "shrink-wrap" licenses (that is, licenses 
included as part of the product packaging). Shrink-wrap licenses are 
not negotiated with or signed by individual licensees and purport to 
take effect upon the opening of the product package. Certain license 
provisions protecting against unauthorized use, copying, transfer, and 
disclosure of the licensed program may be unenforceable under the laws 
of certain jurisdictions and foreign countries. In addition, the laws 
of some countries do not protect proprietary rights to the same extent 
as the laws of the United States. There can be no assurance that these 
protections will be adequate. To the extent that the Company increases 
its international activities, its exposure to unauthorized copying and 
use of its products and proprietary information will increase.

The scope of United States patent protection in the software 
industry is not well defined and will evolve as the United States 
Patent and Trademark Office grants additional patents. Because patent 
applications in the United States are not publicly disclosed until the 
patent is issued, applications may have been filed that would relate to 
Rational's products.

Rational also relies on certain software that it licenses from 
third parties, including software that is  integrated with internally 
developed software and used in its products to perform key functions. 
There can be no assurance that these third-party software licenses will 
continue to be available to the Company on commercially reasonable 
terms or that the software will be appropriately supported, maintained, 
or enhanced by the licensors. The loss of licenses to or inability to 
support, maintain, and enhance any of such software could result in 
increased costs or in delays or deductions in product shipments until 
equivalent software could be developed, identified, licensed, and 
integrated, which would materially adversely affect the Company's 
business, operating results, and financial condition.  In addition, 
Rational licenses certain of its technology to its development 
partners. There can be no assurance that such partners' use of the 
technology will be complementary to Rational's strategies or that such 
partners will not use such technology to develop and market competing 
products in the future.


Risks of Litigation

Competitors and potential competitors may resort to litigation as 
a means of competition. Such litigation or other legal disputes may be 
costly and may expose the Company to new claims that it may not have 
anticipated. In the past, Rational has instituted litigation against 
several companies. Although patent and intellectual property disputes 
in the software area have often been settled through licensing, cross-
licensing, or similar arrangements, costs associated with such 
arrangements may be substantial. The Company is also currently a party 
to securities litigation. Any litigation involving the Company, whether 
as plaintiff or defendant, regardless of the outcome, may result in 
substantial costs and expenses to the Company and significant diversion 
of effort by the Company's technical and management personnel. In 
addition, there can be no assurance that litigation, instituted either 
by or against the Company, will not be necessary to resolve issues that 
may arise from time to time in the future. Any such litigation could 
have a material adverse effect on the Company's business, operating 
results, and financial condition.

Rational expects that software product developers will be 
increasingly subject to infringement claims as the number of products 
and competitors grows and the functionality of products in different 
industry segments overlaps. There can be no assurance that third 
parties will not assert infringement claims against the Company in the 
future or that such claims will not be successful. The Company could 
incur substantial costs in defending itself and its customers against 
any such claims. Parties making such claims may be able to obtain 
injunctive or other equitable relief that could effectively block the 
Company's ability to sell its products in the United States and abroad 
and could result in an award of substantial damages. In the event of a 
claim of infringement, the Company and its customers may be required to 
obtain one or more licenses from third parties. There can be no 
assurance that the Company or its customers could obtain necessary 
licenses from third parties at a reasonable cost or at all. Defense of 
any lawsuit or failure to obtain any such required license would have a 
material adverse effect on the Company's business, results of 
operations, and financial condition.  See also "Item 3-Legal 
Proceedings" of Part I in the Company's latest annual report filed with 
the Securities and Exchange Commission on Form 10-K.


Deferred Tax Assets

In fiscal 1998, the Company recognized approximately $15 million 
out of $45 million previously unrecognized deferred tax assets.  The 
"more likely than not" criteria for recognition had been met as a 
result of current and anticipated operating results. Should the 
Company's operating results not achieve anticipated levels, these 
deferred tax assets may not be realized thereby adversely impacting the 
Company's reported tax expense. The Company has provided a valuation 
allowance on the remaining deferred tax assets as the "more likely than 
not" criteria has not been met.



PART II  --  OTHER INFORMATION

ITEM 1 - Legal Proceedings

On May 28, 1998, a consolidated, amended class action Complaint was 
filed against the Company and Paul D. Levy in the United States 
District Court for the Northern District of California.  That action, 
In re Rational Software Corporation, No. 97-21001 (JF), consolidates 
eight prior-pending, virtually-identical complaints.  SG Cowen & 
Company and an SG Cowen & Company analyst are also named as defendants.  
The complaint alleges that defendants violated Sections 10(b) and 20A 
of the Securities Exchange Act of 1934 and California state securities 
laws through the selective disclosure of material inside information 
regarding the Company's prospects.  The complaint seeks unspecified 
damages on behalf of a class of stockholders who purchased the 
Company's common stock on October 8, 1997.  Defendants' motions to 
dismiss the Complaint were granted, with leave to amend. The Company 
anticipates that plaintiffs will attempt to amend the Complaint. The 
Company further expects to file a motion to dismiss that amended 
Complaint.
