                     CENTRA SOFTWARE, INC. AND SUBSIDIARIES
                   Notes to Consolidated Financial Statements

(1) OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES

         Centra Software, Inc. (together with its wholly-owned subsidiaries,
"Centra" or the "Company"), is a leading provider of software and services that
support live eLearning and real-time business collaboration.

         On January 16, 2002, the Company entered into an Agreement and Plan of
Merger and Reorganization with SmartForce PLC and its wholly-owned subsidiary,
Atlantic Acquisition Corp. Under the merger agreement, holders of the Company's
common stock would have received 0.425 SmartForce American Depository Shares for
each share of the Company's common stock outstanding at the time of the merger.

         On April 2, 2002, the Company entered into a Termination Agreement and
Release with SmartForce and Atlantic. Pursuant to the termination agreement, the
parties agreed to terminate the merger agreement and the related voting
agreements, affiliate agreements and proxies.

         On April 19, 2002, Centra adopted a stockholder rights plan. The rights
plan is designed to help ensure that all of our stockholders receive fair and
equal treatment in the event of any unsolicited proposal to acquire control of
the Company. As part of the rights plan, we designated 300,000 shares of our
authorized preferred stock as series A preferred stock. The adoption of the
stockholder rights plan will affect the rights of holders of the Company's
common stock, and any issuance of shares of series A preferred stock upon
exercise of the rights will also affect the rights of holders of common stock.

         On April 30, 2001, pursuant to an Agreement and Plan of Merger by and
among the Company, MindLever.com, Inc. (MindLever) and M-L Acquisition Co.,
which has been renamed to Centra RTP, Inc., a wholly-owned subsidiary of the
Company, the Company acquired MindLever, a provider of management systems for
learning content, by merging it with and into M-L Acquisition Co. The Company
acquired MindLever for approximately $2.9 million in cash, the issuance of
509,745 shares of common stock valued at approximately $3.8 million and
acquisition costs in the approximate amount of $512,000, for a total purchase
price of approximately $7.2 million. The acquisition was accounted for using the
purchase method in accordance with Accounting Principles Board (APB) Opinion No.
16. Accordingly, the results of operations of MindLever have been included in
the results of operations of the Company from the date of acquisition (see Note
2).

         Centra is subject to certain business risks that could affect its
future operations and financial performance. These risks include, but are not
limited to, rapid technological changes, significant competition, dependence on
key individuals, quarterly performance fluctuations, ability to enhance existing
products and services and to develop new products and services. These and other
risks are described under the heading "Factors That Could Affect Future Results"
in the section of this Report entitled "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

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

(a) Basis of Presentation

         The consolidated financial statements include the accounts of Centra
and its wholly-owned subsidiaries, Centra Software Europe Limited, which was
incorporated in the United Kingdom, Centra Software Securities Corporation, a
Massachusetts securities corporation, Centra RTP, Inc., a Delaware corporation,
Centra Software Southern Europe SAS, which was incorporated in France, and
Centra Software Nordic ApS, which was incorporated in Denmark. All significant
intercompany transactions and balances have been eliminated in consolidation.

                                      6

<PAGE>

         The accompanying consolidated financial statements for the three months
ended March 31, 2001 and 2002 are unaudited, have been prepared on a basis
consistent with the December 31, 2001 audited financial statements and include
normal recurring adjustments which are, in the opinion of management, necessary
for the fair statement of the results of these periods. These consolidated
statements should be read in conjunction with our consolidated financial
statements and notes thereto included in our Form 10-K for the fiscal year ended
December 31, 2001. The results of operations for the three months ended March
31, 2002 are not necessarily indicative of results to be expected for the entire
year or any other period.

(b) Use of Estimates

         The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Those estimates and judgments are based on the Company's
historical experience, the terms of existing contracts, management's observance
of trends in the industry, information that Centra obtains from its customers
and outside sources, and on various other assumptions that it believes to be
reasonable and appropriate under the circumstances, the results of which form
the basis for making judgments about the carrying values of assets and
liabilities that are not readily apparent from other sources. Actual results
could differ materially from these estimates under different assumptions or
conditions.

(c) Revenue Recognition

         Centra derives substantially all of its revenues from the sale of
software licenses, post-contract support (maintenance), and other services.
Maintenance includes telephone support, bug fixes and rights to upgrades and
enhancements on a when-and-if available basis. Other services include training,
basic implementation consulting to meet specific customer needs, software
application hosting and application service provider (ASP) services. Centra
executes contracts that govern the terms and conditions of each software
license, maintenance arrangement and other services arrangements. These
contracts may be elements in a multiple-element arrangement. Revenue under
multiple-element arrangements, which may include several different software
products and services sold together, is allocated to each element based on the
residual method in accordance with the American Institute of Certified Public
Accountants (AICPA) Statement of Position 98-9, Software Revenue Recognition
with Respect to Certain Arrangements.

         Centra uses the residual method when vendor-specific objective evidence
of fair value does not exist for one of the delivered elements in the
arrangement. Under the residual method, the fair value of the undelivered
elements is deferred and subsequently recognized. Centra has established
sufficient vendor-specific objective evidence for the value of its consulting,
training and other services, based on the price charged when these elements are
sold separately. Accordingly, software license revenues are recognized under the
residual method in arrangements in which software is licensed with consulting,
training, and other services.

         Revenues from license fees are recognized when persuasive evidence of
an agreement exists, delivery of the product has occurred, the fee is fixed or
determinable and collectability is probable. Advance payments are recorded as
deferred revenue until the products are shipped, services are delivered or
obligations are met. Centra's products do not require significant customization.
Billings to customers are generally due within 90 days of the invoice date. The
Company has offered extended payment terms greater than 90 days but less than 12
months to certain of its customers, for which license revenue is recognized upon
shipment. These customers are well capitalized and typically have entered into
enterprise-wide license arrangements with the Company. The Company believes that
it has sufficient history of collecting all amounts within the stated terms
under these types of arrangements to conclude that the fee is fixed or
determinable at the time of license revenue recognition.

         Revenues related to maintenance and software application hosting are
recognized on a straight-line basis over the period that the maintenance and
hosting services are provided. Revenues related to ASP services are recognized
on a straight-line basis over the period that the ASP services are provided, or
on an as-used basis if defined in the contract. Revenues allocable to
implementation, consulting and training services are recognized either as the
services are performed, ratably over a subscription period, or upon completing
project milestones if defined in the agreement.

         We record as deferred revenues any billed amounts due from customers in
excess of revenues recognized. Deferred revenues consist principally of contract
maintenance, ASP service and consulting services.

(d) Cash Equivalents and Short-Term Investments

         Centra considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents. Centra's cash
equivalents consisted of the following at December 31, 2001 and March 31, 2002

         Centra accounts for short-term investments in accordance with Statement
of Financial Accounting Standards (SFAS) No. 115, Accounting for Certain
Investments in Debt and Equity Securities. Under SFAS No. 115, investments for
which Centra has the positive intent and the ability to hold to maturity are
reported at amortized cost, which approximates fair market value. At December
31, 2001 and March 31, 2002, Centra's short-term investments consisted of the
following (in thousands):

         In January 2001, the Company liquidated, prior to maturity, certain
short-term obligations of California-based utilities when their ratings dropped
to below investment grade. This resulted in a realized loss of approximately
$772,000.

(e) Comprehensive Loss

         The Company applies the provisions of SFAS No. 130, Reporting
Comprehensive Income, which establishes standards for reporting and displaying
comprehensive income and its components in the consolidated financial
statements. Comprehensive income (loss) is defined as the change in equity of a
business enterprise during a period from transactions and other events and
circumstances from non-owner sources. The only components of comprehensive loss
reported by the Company are net loss and foreign currency translation
adjustments.

                                                                Three Months

accordance with SFAS No. 128, basic and diluted net loss per share has been
computed by dividing net loss by the weighted-average number of shares of common
stock outstanding during the period, less shares subject to repurchase of
571,000 and 279,000 for the three months ended March 31, 2001 and 2002,
respectively.

         Options to purchase a total of 4,656,144 and 4,936,628 shares of common
stock have not been included in the computation of diluted earnings per share
above for the three months ended March 31, 2001 and 2002, respectively.
Inclusion of these shares would have an antidilutive effect, as Centra has
recorded a loss for all periods presented.

         Common stock outstanding as of December 31, 2001 and March 31, 2002
includes 54,438 shares issued but held in escrow in connection with the
Company's acquisition of MindLever.com in April, 2001. These shares will be
released from escrow after April 30, 2002 pursuant to the MindLever merger
agreement. These shares have not been included in the computation of diluted
earnings per share above for the three months ended March 31, 2001 and 2002,
respectively.

(h) Segment Information

         SFAS No. 131, Disclosures about Segments of an Enterprise and Related
Information, establishes standards for reporting information regarding operating
segments and establishes standards for related disclosures about products and
services and geographic areas. Operating segments are identified as components
of an enterprise about which separate discrete financial information is
available for evaluation by the chief operating decision maker, or decision
making group, in making decisions regarding resource allocation and assessing
performance.

         Centra operates solely in one segment, the development and marketing of
software products and related services. Centra's revenues are as follows (based
on location of customer):

         There are no significant long-lived assets located outside of the
United States.

(i) Recent Accounting Pronouncements

         In July 2001, the Financial Accounting Standards Board (FASB) issued
SFAS No. 141, Business Combinations. SFAS No. 141 requires all business
combinations initiated after June 30, 2001, to be accounted for using the
purchase method. This statement is effective for all business combinations
initiated after June 30, 2001.

         In July 2001, the FASB issued SFAS No. 142, Goodwill and Other
Intangible Assets. SFAS No. 142 applies to goodwill and intangible assets
acquired after June 30, 2001, as well as goodwill and intangible assets
previously acquired. Under this statement, goodwill, as well as certain other
intangible assets determined to have indefinite lives, will no longer be
amortized. Instead, these assets will be reviewed for impairment on a periodic
basis, at least annually. This statement was effective for the Company in the
first quarter of its fiscal year ending December 31, 2002. As of January 1,
2002, the Company ceased amortizing goodwill and reclassified assembled
workforce to goodwill. The Company obtained a preliminary third party appraisal
and does not believe these assets are impaired and, accordingly, the adoption of
SFAS No. 142 is expected to reduce the Company's amortization expense by
approximately $1.3 million in fiscal 2002 and 2003, $1.2 million in 2004 and
2005 and $400,000 in 2006. The Company will continue to review these assets for
impairment on at least an annual basis.

         In August 2001, the FASB issued SFAS No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets. This statement supercedes SFAS No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of, and the accounting and reporting provisions of APB
Opinion No. 30, Reporting the Results of Operations - Reporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently
Occurring Events and Transactions. Under SFAS No. 144 it is required that one
accounting model be used for long-lived assets to be disposed of by sale,
whether previously held and used or newly acquired, and it broadens the
presentation of discontinued operations to include more disposal transactions.
The provisions of this statement are effective for financial statements issued
for fiscal years beginning after December 15, 2001, and interim periods within
those fiscal years, with early adoption permitted. The adoption of this
statement did not have a material impact on the Company's financial statements.


(j) MindLever.com Acquisition

      On April 30, 2001, pursuant to an Agreement and Plan of Merger by and
among the Company, MindLever.com, Inc. (MindLever) and M-L Acquisition Co., a
wholly-owned

                                      9

<PAGE>

subsidiary of the Company, the Company acquired MindLever, a provider of
management systems for learning content, by merging it with and into M-L
Acquisition Co. The Company acquired MindLever for approximately $2.9 million in
cash, the issuance of 509,745 shares of common stock in the amount of
approximately $3.8 million and acquisition costs in the approximate amount of
$512,000, for a total purchase price of approximately $7.2 million. The
acquisition was accounted for using the purchase method in accordance with APB
No. 16. Accordingly, the results of operations of MindLever have been included
in the results of operations of the Company from the date of acquisition.

      The following table summarizes the allocation of the purchase price (in
thousands):

                                                                     Amount
                                                                ---------------
Acquisition of MindLever:
 Net liabilities assumed, at fair value.............................$ (3,281)
 In-process research and development................................   2,200
 Developed technology and know-how..................................   2,100
 Assembled workforce................................................     300
 Goodwill...........................................................   5,873
                                                                   ---------
                                                                    $  7,192
                                                                   =========

      As part of the purchase price allocation, all intangible assets acquired
from MindLever were identified and valued by a third party appraiser. It was
determined that technology assets and assembled workforce had value. As a result
of this identification and valuation process, the Company allocated $2.2 million
of the purchase price to in-process research and development projects. This
allocation represents the estimated fair value based on risk-adjusted cash flows
related to the incomplete research and development projects. At the date of
acquisition, the development of the projects had not yet reached technical
feasibility, and the research and development in progress had no alternative
future uses. Accordingly, these costs were expensed as of the date of
acquisition.

      Developed technology represents technology and know-how related to
MindLever's current learning content management solution. Developed technology
is being amortized over a period of three years. Assembled workforce is the
presence of a skilled workforce that is knowledgeable about company procedures
and possesses expertise in certain fields that are important to continued
profitability and growth of a company. Assembled workforce was being amortized
over a period of three years until the adoption of SFAS 142 in January 2002,
when the Company ceased amortization of assembled workforce and goodwill and
will assess annually for impairment.

      The excess of the purchase price over the fair value of the identifiable
intangible net assets of approximately $5.9 million was allocated to goodwill
was being amortized over a period of five years until the adoption of SFAS 142
in January 2002, when the Company ceased amortization of goodwill and will
assess annually for impairment.

      Accumulated amortization of developed technology, assembled workforce and
goodwill was $641,667, $66,667 and $782,878, respectively as of March 31, 2002.

      Unaudited pro forma operating results for the Company for the three months
ended March 31, 2001, assuming the acquisition of MindLever occurred at the
beginning of fiscal 2001 are as follows (in thousands, except per share data):

                                                          Three Months
                                                     Ended March 31, 2001
                                                     --------------------

Revenues...................................................$ 9,378
Net loss................................................... (6,555)
Net loss per share, basic and diluted......................$ (0.27)

      For purposes of these pro forma operating results, the in-process research
and development was assumed to have been written off prior to the pro forma
period, so that the operating results presented only include recurring costs.

OVERVIEW

              We design, develop, market and support software infrastructure and
application service provider (ASP) services for live eLearning and real-time
business collaboration. Our enterprise products provide a comprehensive range of
knowledge delivery and services which include features such as
voice-over-the-Internet, software application sharing, real-time data exchange,
shared workspaces, record and playback and standards-compliant content
management and monitoring. Our products to date have been sold primarily to
Global 2000 businesses and have consisted of product offerings and network
service solutions for corporate eLearning and training, collaborative sales and
marketing, and one-to-one customer, partner and employee relationships.

         Through March 31, 2002, our revenues were derived from licenses of our
software products, from related maintenance, and from the delivery of
implementation consulting, training, education, hosting and ASP services. We
price the license of our enterprise application software on a rental or purchase
basis under a variety of licensing models, including perpetual named-user
licenses, perpetual concurrent-user licenses, time-limited licenses and
revenue-sharing. Customers who license our enterprise application software
typically purchase renewable maintenance contracts that provide telephone
support, bug fixes and rights to unspecified upgrades and enhancements on a
when-and-if available basis over a stated term, usually a twelve-month period.
Maintenance is priced as a percentage of our license fees. We also offer
implementation consulting, training and education services to our customers,
primarily on a time-and-materials basis, but also for education, on a course
subscription or per-course basis. In addition, we offer hosting services for
customers under hosting agreements, with terms typically ranging from six to
twelve months, to outsource the administration and infrastructure necessary to
operate our enterprise application software. The hosting fees include a set-up
fee and monthly service fee in addition to license fees for the software.
Finally, we offer all of our license products as an ASP service, with terms
typically ranging from three to twelve months. The ASP service fees include a
set-up fee and monthly, hourly or per event subscription fee.

         We sell our products and services primarily through a direct sales
force and through relationships with distributors, resellers and other strategic
partners. We have established European direct sales and service operations
headquartered in the United Kingdom and have master distributors in Japan and
Korea. In addition, we have value added resellers throughout Europe, the Middle
East, the Pacific Rim, China, India, Brazil, South Africa and Central America.
Revenues from sales outside the United States were 22% of total revenues or $2.0
million for the three month period ended March 31, 2001, and 33% of total
revenues or $2.5 million for the three month period ended March 31, 2002. Since
1999 we have invested in the infrastructure necessary to expand our global
operations, including the formation and staffing of our European subsidiaries
and our Asian operations. We expect to continue to invest in our international
operations as we expand our international direct and indirect channels and our
ASP service operations locally to increase worldwide market share. We anticipate
that revenues derived from outside the United States will continue to increase
both in terms of percentage of revenues and absolute dollars.

         Our cost of license revenues includes royalties due to third parties
for technology included in our products, as well as costs of product
documentation, media used to deliver our products and fulfillment. Our cost of
service revenues includes (a) salaries and related expenses for our consulting,
education, technical support and information technology services organizations,
(b) an overhead allocation consisting

                                      11

<PAGE>

primarily of that portion of our facilities, communications and depreciation
expenses that are attributable to providing our services, and (c) direct costs
related to our hosting and ASP service offerings.

         Our operating expenses are classified into six general categories:
sales and marketing, product development, general and administrative,
compensation charge for issuance of stock options, amortization of intangible
assets and merger transaction costs.

         .        Sales and marketing expenses consist primarily of (a) salaries
         and other related costs for sales and marketing personnel and (b) costs
         associated with marketing programs, including trade shows, user group
         meetings and seminars, advertising, public relations activities and new
         product launches.

         .        Product development expenses consist primarily of employee
         salaries and benefits, fees for outside consultants and related costs
         associated with the development of new products, the enhancement of
         existing products, purchase of third party source code, quality
         assurance, testing, documentation and third party localization costs.

         .        General and administrative expenses consist primarily of
         salaries and other related costs for executive, financial,
         administrative and information technology personnel, as well as
         accounting, legal, investor relations and other costs associated with
         being a public company.

         .        Compensation charge for issuance of stock options represents
         the amortization, over the vesting period of the option, of the
         difference between the exercise price of options granted to employees
         and the deemed fair market value of the options for financial reporting
         purposes.

         .        Amortization of intangible assets represents the amortization,
         over a three year period, of the valuation of the developed technology
         and know-how.

         .        Merger transaction costs represent the costs that were
         incurred as of March 31, 2002 related to the proposed merger of Centra
         Software, Inc. and SmartForce PLC. The proposed merger was terminated
         as of April 2, 2002.

         In the development of new products and enhancements of existing
products, the technological feasibility of the software is not established until
substantially all product development is complete. Historically, our software
development costs eligible for capitalization have been insignificant and all
costs related to internal product development have been expensed as incurred.

         We have experienced substantial losses in each fiscal period since our
inception. As of March 31, 2002, we had an accumulated deficit of $63.6 million.
These losses and our accumulated deficit have resulted from our initial lack of
substantial revenues, as well as the significant costs incurred in the
development of our products and services and in the preliminary establishment of
our infrastructure which have been only partially offset by our revenues to
date. We expect to maintain the same level or slightly increase our expenditures
in all areas in order to execute our business plan and to expand further
internationally.

         Additionally, although we have experienced revenue growth in the past,
we have recently experienced declining revenues and increased losses. We may not
be able to increase our revenues or to attain profitability and, if we do
achieve profitability, we may not be able to sustain profitability for any
future periods. Accordingly, we expect to incur additional losses during 2002.
We believe that period-to-period comparisons of our historical operating results
may not be meaningful, and you should not rely upon them as an indication of our
future financial performance.

CRITICAL ACCOUNTING POLICIES

         The preparation of our financial statements requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and the 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. On an ongoing basis, management evaluates its
estimates and judgments, including those related to revenue recognition and the
valuation of long-lived assets. Management bases its estimates and judgments on
historical experience and on various other factors that are believed to be
reasonable under the circumstances. Actual results may differ from these
estimates under different assumptions or conditions.

    We believe the following critical accounting policies most significantly
affect the portrayal of our financial condition and require management's most
difficult and

                                      12

<PAGE>

subjective judgments.

REVENUE RECOGNITION

         Not only is revenue recognition a key component of our results of
operations, the timing of our revenue recognition also determines the timing of
certain expenses, such as commissions. In measuring revenues, we follow the
specific guidelines of SOP 97-2 "Software Revenue Recognition," and SOP 98-9
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions," and related authoritative literature. Certain judgments of
management, however, affect the application of this policy. Revenue results are
difficult to predict and any shortfall or delay in recognizing revenue could
cause our operational results to vary significantly from quarter to quarter. We
maintain allowances for estimated losses resulting from the inability of our
customers to make required payments. However, if the financial condition of our
customers were to deteriorate, resulting in an impairment of their ability to
make payments, additional allowances for bad debts would be required.

VALUATION OF LONG-LIVED ASSETS

         We assess the impairment of long-lived assets whenever events or
changes in circumstances indicate that the carrying value may not be
recoverable. If we determined that the carrying value of long-lived assets and
goodwill might not be recoverable based upon the existence of one or more
indicators of impairment, we would measure any impairment based on a projected
discounted cash flow method. While we believe that our estimates of future cash
flows are reasonable, different assumptions regarding such cash flows could
materially affect our evaluations.

RESULTS OF OPERATIONS

         The following table sets forth operating data expressed as percentages
of total revenues for each period indicated.

Comparison of three months ended March 31, 2001 and 2002

 Revenues.    Total revenues decreased by $1.6 million, or 17%, to $7.5 million
for the three months ended March 31, 2002, from approximately $9.1 million for
the three months ended March 31, 2001. The decrease was attributable to a
significant decrease in license

                                      13

<PAGE>

revenues in North America offset by increased service revenues.

License revenues decreased by $3.4 million, or 47%, to $3.8 million for the
three months ended March 31, 2002, from $7.2 million for the three months ended
March 31, 2001. The decrease resulted from a shortfall in North American license
sales. Several other factors also contributed to the decrease, including a
difficult economic environment resulting in longer sales cycles, reduced
productivity of the Company's sales force and the temporary diversion of
resources and management attention associated with the Company's proposed merger
with SmartForce during the quarter. Although we believe some of these factors
may be temporary, we cannot predict the timing of when or if these factors would
reverse in future periods.

Service revenues increased by $1.8 million, or 98%, to $3.7 million for the
three months ended March 31, 2002, from $1.9 million for the three months ended
March 31, 2001. The increase was primarily related to an increase in maintenance
support contracts to new and existing customers, ASP revenue, and to a lesser
extent, an increase in education, consulting and hosting services. We expect
service revenues, including ASP, to increase in absolute dollars in future
periods.

 Cost of license revenues. Cost of license revenues decreased by $58,000, or
39%, to $89,000 for the three months ended March 31, 2002, from $147,000 for the
three months ended March 31, 2001. The decrease was primarily attributable to
expiration of a royalty for software which is no longer used in our products,
and to a lesser extent, lower license revenue levels. We anticipate that cost of
license revenues will increase in the future both in terms of absolute dollars
as licensing revenues from our products increase and as a percent of license
revenues due to the licensing of additional technologies from third parties.

 Cost of service revenues. Cost of service revenues increased by $147,000, or
9%, to $1.7 million for the three months ended March 31, 2002, from $1.6 million
for the three months ended March 31, 2001. The increase was primarily the result
of increased technical support and ASP personnel providing services to our
customers in North America and Europe, as well as increases in infrastructure
costs associated with providing our ASP service. We anticipate that the cost of
service revenues will continue to increase in absolute dollars to the extent
that we continue to generate new customers and associated license and service
revenues. We believe that cost of service revenues as a percentage of service
revenues can be expected to vary significantly from period to period depending
on the mix of services that we provide and overall utilization rates of our
service personnel and our ASP service capacity.

 Sales and marketing expenses. Sales and marketing expenses decreased by $1.2
million, or 19%, to $5.1 million for the three months ended March 31, 2002, from
$6.3 million for the three months ended March 31, 2001. The decrease was mainly
attributable to a decrease in marketing programs, including advertising, trade
shows, and promotional expenses, and to a lesser extent a decrease in
commissions expense due to lower license revenues. We expect that sales and
marketing expenses will increase slightly in absolute dollars in future periods.

 Product development expenses. Product development expenses increased by
$488,000, or 19%, to $3.1 million for the three months ended March 31, 2002,
from $2.6 million for the three months ended March 31, 2001. The increase
primarily resulted from an increase in product development personnel. We believe
that continued investment in product development is critical to achieving our
strategic objectives and, as a result, we expect product development expenses
will continue to increase in absolute dollars as additional product development
personnel are added and additional investments are made into third party source
code.

 General and administrative expenses. General and administrative expenses
decreased slightly by $33,000, or 2%, to $1.9 million for the three months ended
March 31, 2002, from $1.9 million for the three months ended March 31, 2001. We
expect that general and administrative expenses will remain relatively constant
in absolute dollars for the foreseeable future.

 Compensation charge for issuance of stock options. We incurred a charge of
$218,000 for the three months ended March 31, 2002, as compared to $223,000 for
the three months ended March 31, 2001, related to the issuance of stock options
to employees and non-employees during 1999 and 2000. These options which vest
over periods up to five years, will result in additional compensation expense of
approximately $1.1 million through September 2003.

 Amortization of intangible assets. We recognized amortization on developed
technology and know-how acquired from Mindlever in April 2001 in the amount of
$175,000 for the three months ended March 31, 2002. In conjunction with our
acquisition of MindLever in April 2001, we allocated approximately $5.9 million
to goodwill, $2.1 million to developed technology and know-how and $300,000 to
assembled workforce. As of January 1,

                                      14

<PAGE>

2002 in accordance with SFAS 142, goodwill and assembled workforce, were no
longer amortized. Instead, these assets are reviewed for impairment on an annual
basis.

Merger transaction costs. We incurred a charge of $1.2 million for the three
months ended March 31, 2002, related to the proposed merger of the Company and
SmartForce. The merger was terminated on April 2, 2002. The costs consists
primarily of advisory fees, legal fees, retainer fees and other related expenses
associated with the proposed merger.

Other income, net. Other income, net of interest and other expense, decreased by
$556,000 to $169,000 for the three months ended March 31, 2002, from $725,000
for the three months ended March 31, 2001. Other income consists primarily of
interest on cash and short-term investments. The decrease resulted from a lower
average cash balance and lower average interest rates on invested cash and
short-term investments for the three months ended March 31, 2002 compared to the
three months ended March 31, 2001.

Loss on sale of short-term investments. In January, 2001, we liquidated, prior
to maturity, certain short-term debt obligations of California-based utilities
when their ratings dropped to below investment grade which resulted in a
realized loss of approximately $772,000 for the three months ended March 31,
2001.

LIQUIDITY AND CAPITAL RESOURCES

         As of March 31, 2002, we had cash and cash equivalents of $22.1 million
and short-term investments of $23.3 million, a decrease of $3.3 million of cash
and cash equivalents from $25.4 million at December 31, 2001 and an increase of
$512,000 of short-term investments from $22.8 million as of December 31, 2001.
The net combined decrease of $2.8 million for cash, cash equivalents and
short-term investments resulted primarily from cash used to fund operations,
purchases of fixed assets and payments on term loans. Our working capital as of
March 31, 2002 was $36.5 million, compared to $42.2 million as of December 31,
2001.

         Net cash used in operating activities was $2.0 million for the three
months ended March 31, 2002, primarily the result of operating losses incurred
during the quarter of $5.9 million, offset by a decrease in accounts receivable
of $2.8 million, non-cash expenses of $1.0 million and an increase in accounts
payable of $840,000. Also contributing, to a lesser extent, to the net cash used
in operating activities was an increase in prepaid expenses and a decrease in
accrued expenses, partially offset by an increase in deferred revenue. Net cash
used in operating activities was $3.8 million for the three months ended March
31, 2001, primarily due to operating losses incurred during the quarter, as well
as an increase in accounts receivable and a decrease in accrued expenses,
partially offset by non cash expenses, including a loss on the sale of certain
short-term obligations of California-based utilities, and by an increase in
accounts payable and decreases in prepaid expenses and deferred revenue.

         Net cash used in investing activities was $1.1 million for the three
months ended March 31, 2002, resulting from purchases of property and equipment
to support operations and net purchases of short-term investments. Net cash
provided from investing activities was $10.4 million for the three months ended
March 31, 2001, resulting from net maturities of short-term investments reduced
by purchases of property and equipment.

         Net cash used in financing activities was $54,000 and $263,000 for the
three months ended March 31, 2001 and 2002, respectively, resulting from
payments made under term loans and capital lease obligations, partially offset
by receipts from the exercise of stock options.

         On May 4, 2001, we amended our equipment line of credit agreement to
allow for $4.5 million in borrowings of which approximately $3.8 million was
outstanding at March 31, 2002. Interest is payable monthly based on the prime
rate (4.75% at March 31, 2002) plus .5%. Amounts outstanding are payable in 36
equal monthly installments beginning on October 1, 2001. Additionally, at March
31, 2002, we had outstanding borrowings under the original equipment line of
credit of $41,000, bearing interest at the rate of prime plus 1% per annum. All
borrowings are secured by substantially all of our assets. This amended line of
credit requires us to maintain a minimum balance of cash, cash equivalents and
short term investments of $30 million. We were in compliance with our covenants
under the equipment line of credit at March 31, 2002.

         Capital expenditures totaled $866,000 and $620,000 for the three month
periods ended March 31, 2001 and 2002, respectively. Our capital expenditures
consisted of operating assets to manage our operations, including computer
hardware and software, office furniture and equipment and leasehold
improvements. Purchases of computer equipment represent the largest component of
our capital expenditures. We expect capital expenditures to continue for the
foreseeable future as we increase the number of customers that we provide
services to under our ASP offering, improve and expand our information systems
and replace older and outdated computer hardware with newer

                                      15

<PAGE>

equipment. Since inception, we have generally funded capital expenditures either
through the use of working capital or with equipment bank loans.

         Days sales outstanding in accounts receivable at March 31, 2002 were 82
days, a slight increase of 3 days from the prior quarter.

         We expect to continue to experience significant growth in our capital
expenditures, cost of revenues and, to a lesser extent, operating expenses,
particularly sales and marketing and product development expenses, for the
foreseeable future in order to execute our business plan. We believe that our
existing cash balances, will be sufficient to finance our operations through at
least the next 12 months. However, thereafter, we may need to raise additional
funds to support more rapid expansion of our sales force, develop new or
enhanced products or services, respond to competitive pressures, acquire
complementary businesses or technologies or respond to unanticipated
requirements. If we seek to raise additional funds, we may not be able to obtain
funds on terms which are favorable or acceptable to us. If we raise additional
funds through the issuance of equity securities, the percentage ownership of our
existing stockholders would be reduced. Furthermore, the securities could have
rights, preferences or privileges senior to our common stock.

RECENT ACCOUNTING PRONOUNCEMENTS

         In July 2001, the Financial Accounting Standards Board (FASB) issued
SFAS No. 141, Business Combinations. SFAS No. 141 requires all business
combinations initiated after June 30, 2001, to be accounted for using the
purchase method. This statement is effective for all business combinations
initiated after June 30, 2001.

         In July 2001, the FASB issued SFAS No. 142, Goodwill and Other
Intangible Assets. SFAS No. 142 applies to goodwill and intangible assets
acquired after June 30, 2001, as well as goodwill and intangible assets
previously acquired. Under this statement, goodwill, and certain other
intangible assets determined to have indefinite lives, will no longer be
amortized. Instead, these assets will be reviewed for impairment on a periodic
basis, at least annually. This statement was effective for the Company in the
first quarter of its fiscal year ending December 31, 2002. As of January 1,
2002, the Company ceased amortizing goodwill and reclassified assembled
workforce to goodwill. The Company obtained a preliminary third party appraisal
and does not believe these assets are impaired. The adoption of SFAS No. 142 is
expected to reduce the Company's amortization expense by approximately $1.3
million in fiscal 2002 and 2003, $1.2 million in 2004 and 2005 and $400,000 in
2006. The Company will continue to review these assets for impairment on at
least an annual basis.

         In August 2001, the FASB issued SFAS No. 144, Accounting for the
Impairment or Disposal of Long-Lived Assets. This statement supercedes SFAS No.
121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of, and the accounting and reporting provisions of APB
Opinion No. 30, Reporting the Results of Operations - Reporting the Effects of
Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently
Occurring Events and Transactions. Under SFAS No. 144 it is required that one
accounting model be used for long-lived assets to be disposed of by sale,
whether previously held and used or newly acquired, and it broadens the
presentation of discontinued operations to include more disposal transactions.
The provisions of this statement are effective for financial statements issued
for fiscal years beginning after December 15, 2001, and interim periods within
those fiscal years, with early adoption permitted. The adoption of this
statement did not have a material impact on our financial statements.

FACTORS THAT COULD AFFECT FUTURE RESULTS

         As defined under the safe harbor provisions of The Private Securities
Litigation Reform Act of 1995, some of the matters discussed in this filing
contain "forward-looking statements" regarding future events that are subject to
risks and uncertainties. The following factors, among others, could cause actual
results to differ materially from those described by such statements. These
factors include, but are not limited to: achieving market acceptance for our ASP
network service and our Centra eMeeting and Knowledge Center products, quarterly
fluctuations in operating results attributable to the timing and amount of
orders for our products and services, failure to effect, or if effected, to
manage anticipated growth, failure to enhance our existing products and services
and to develop and introduce new products and services and other risk factors
contained in the section titled "Factors That Could Affect Future Results"
beginning on page 22 of our annual report on Form 10-K for the period ended
December 31, 2001. If any of these factors actually occur, our business,
financial condition or results of operations could be seriously harmed and the
trading price of our common stock could decline.

         In the future, we may acquire additional businesses or product lines.
Our previously completed acquisition, or any future acquisition, may not produce
the

                                      16

<PAGE>

revenue, earnings or business synergies that we anticipated, and an acquired
product, service or technology might not perform as expected. Prior to
completing an acquisition, however, it is difficult to determine if benefits
expected in the transaction can actually be realized. The process of integrating
acquired companies into our business may also result in unforeseen difficulties.
Unforeseen operating difficulties may absorb significant management attention,
which we might otherwise devote to our existing business. Also, the process may
require significant financial resources that we might otherwise allocate to
other activities, including the ongoing development or expansion of our existing
operations.

         If we pursue a future acquisition, our management could spend a
significant amount of time and effort identifying and completing the
acquisition. If we make a future acquisition, we could issue equity securities
which would dilute current stockholders' percentage ownership, incur substantial
debt, assume contingent liabilities, incur a one-time charge or be required to
amortize intangibles. Also, we could spend a considerable amount of time, money
and management effort pursuing a potential business combination, and then decide
not to proceed with the transaction. In such an event, as in the case of our
recent merger negotiations with SmartForce, we would not likely be able to
recoup expenses incurred during the negotiations.


ITEM 3.       QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         We develop products in the United States and sell them worldwide. As a
result, our financial results could be affected by factors such as changes in
foreign currency exchange rates or weak economic conditions in foreign markets.
Since a significant portion of our international sales are currently priced in
U.S. dollars and translated to local currency amounts, a strengthening of the
dollar could make our products less competitive in foreign markets. Interest
income and expense are sensitive to changes in the general level of U.S.
interest rates, particularly because our investments are in short-term
instruments and our long-term debt and available line of credit require interest
payments calculated at fixed and variable rates. Based on the nature and current
levels of our investments and debt, however, we have concluded that we face no
material market risk exposure.

         In January 2001, we liquidated, prior to maturity, certain short-term
obligations of California based utilities when their ratings dropped to below
investment grade which resulted in a realized loss of approximately $772,000.

         Our general investing policy is to limit the risk of principal loss and
ensure the safety of invested funds by limiting market and credit risk. We
currently use a registered investment manager to place our investments in highly
liquid money market accounts and government backed securities. All highly liquid
investments with original maturities of three months or less are considered to
be cash equivalents.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

         From time to time Centra has been, and expects to continue to be,
subject to legal proceedings and claims in the ordinary course of its business.
Such claims, even if not meritorious, could result in the expenditure of
significant financial and managerial resources.

SECURITIES CLASS ACTION LAWSUIT

         Centra, certain of its officers and directors and the managing
underwriters of Centra's initial public offering have been named as defendants
in an action filed in the United States District Court for the Southern District
of New York. The plaintiff filed an initial complaint filed on December 6, 2001
and purported to serve the Centra defendants on or about March 18, 2002. The
original complaint has been superceded by an amended complaint ("complaint")
filed in April 2002. The action, captioned In re Centra Software, Inc. Initial
Public Offering Securities Litigation, No. 01 CV 10988, is purportedly brought
on behalf of the class of persons who purchased Centra's common stock between
February 3, 2000 and December 6, 2000. The complaint asserts claims under
Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of
the Securities Exchange Act of 1934. The complaint alleges that, in connection
with Centra's initial public offering in February 2000, the underwriters
received undisclosed commissions from certain investors in exchange for
allocating shares to them and also agreed to allocate shares to certain
customers in exchange for the agreement of those customers to purchase
additional shares in the after-market at pre-determined prices. The complaint
asserts that Centra's registration statement and prospectus for the offering
were materially false and misleading due to their failure to disclose these
alleged arrangements. The complaint seeks damages in an unspecified amount
against Centra and the named individuals. To date, the Court has not established
a time for responding to the complaint. Centra intends to vigorously defend
against the allegations, which it believes lack merit.

ITEM 2. CHANGES IN SECURITIES AND USE OF PROCEEDS

         (a-b)    On April 19, 2002, we adopted a stockholder rights plan. The
                  rights plan is designed to help ensure that all of our
                  stockholders receive fair and equal treatment in the event of
                  any unsolicited proposal to acquire

                                      17

<PAGE>

                  control of our company. As part of the rights plan, we
                  designated 300,000 shares of our authorized preferred stock as
                  series A preferred stock. The adoption of our stockholder
                  rights plan will affect the rights of holders of our common
                  stock, and any issuance of shares of series A preferred stock
                  upon exercise of the rights of holders of common stock.

                  As part of the stockholders rights plan, our board of
                  directors declared a distribution of one right for each
                  outstanding share of our common stock. We will issue these
                  rights to our stockholders of record on May 15, 2002. After
                  that date, unless the rights have been redeemed or have
                  expired, we will issue rights with respect to shares of common
                  stock issued before the rights become exercisable and, in
                  certain circumstances, with respect to shares of common stock
                  issued after the rights become exercisable. Each right, when
                  it becomes exercisable will initially entitle the holder to
                  purchase from us one one-thousandth (1/1,000) of a share of
                  series A preferred stock for $29.00.

         (c)      In the three months ended March 31, 2002, we granted options
                  to purchase 96,250 shares of our common stock and we issued
                  143,448 shares of our common stock upon the exercise of
                  employee stock options.

         (d)      Use of Proceeds from Sales of Registered Securities

                  On February 8, 2000 we closed the initial public offering of
                  our common stock. The shares of common stock sold in the
                  offering were registered under the Securities Act of 1933, as
                  amended, on a Registration Statement on Form S-1 (the
                  "Registration Statement") (Registration No. 333-89817) that
                  was declared effective by the Securities and Exchange
                  Commission on February 3, 2000. The aggregate proceeds from
                  the offering were $80.5 million. Our net proceeds from the
                  offering were approximately $73.2 million. From the effective
                  date through March 31, 2002, we used approximately $6.5
                  million for payments of dividends to preferred shareholders,
                  $20.1 million to fund operations, $2.1 million for capital
                  expenditures, $1.7 million for payment of MindLever debt, $3.3
                  million for the MindLever acquisition and $1.4 million to pay
                  amounts outstanding under our loans. As of March 31, 2002, we
                  had approximately $38.1 million of net proceeds remaining, and
                  pending use of these proceeds, we intend to invest such
                  proceeds primarily in highly liquid money market accounts and
                  government backed securities.
