CENTRA SOFTWARE, INC. AND SUBSIDIARIES



Notes to Unaudited Consolidated Financial Statements



(1)
Operations and Significant Accounting Policies



Centra Software, Inc.,
together with its wholly-owned subsidiaries (Centra or the Company), is a provider of solutions software and services for online learning and training. Centras solutions increase productivity and lower operational costs for global
corporations, government agencies and universities by creating workforce efficiencies that enable organizations to share and exchange business-critical information with geographically distributed customers, partners, prospects and employees. Centra
enables groups to work faster and more effectively by automating critical learning and training initiatives online through virtual classrooms, online meetings and Web conferences. Centras solutions address enterprise-application training and
support, workforce development, customer, sales and channel training and compliance training.



On October 5, 2005, Centra entered into an Agreement and Plan of Reorganization with Saba Software, Inc. (Saba), and two wholly-owned subsidiaries of Saba. Under the merger agreement, holders of Centra common
stock will receive 0.354 shares of Saba and $.663 for each share of Centra common stock outstanding at the time of the merger. The merger, which is expected to close in the first calendar quarter of 2006, is subject to certain conditions including
the approval of the merger by Centras stockholders and the approval by Sabas stockholders of the issuance of Saba shares in the merger. The merger is intended to qualify as a tax-free reorganization within the meaning of Section 368
of the Internal Revenue Code of 1986, as amended, and will be accounted for as a purchase transaction by Saba.



Centra is subject to certain business risks that could affect future operations and financial performance. These risks include, but are not limited to, failure to complete our proposed merger with Saba, failure to
successfully execute its strategic plan, the effect of cost-cutting measures on operations, demand for and acceptance of the Centra 7.5 platform and new add-on modules, significant competition, changes in senior management, dependence on key
individuals, quarterly performance fluctuations, evolution and growth of the online business communications and collaboration market and Centras ability to enhance existing products and services and to develop new products and services.



The accompanying consolidated financial statements reflect the application of
certain accounting policies, as described in this note and more fully in the notes to the audited consolidated financial statements included in the Companys Annual Report on Form 10-K for the year ended December 31, 2004.



(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, and Centra Software Australia Pty.
Ltd, which was incorporated in Australia. Centra Software Southern Europe SAS was incorporated in France and was included in the consolidated financial statements until it was dissolved in January 2005. Centra Software Nordic ApS was incorporated in
Denmark and was included in the consolidated financial statements until it was dissolved in February 2004. All significant intercompany transactions and balances have been eliminated in consolidation.



The accompanying consolidated financial statements for the three and nine months ended
September 30, 2004 and 2005 are unaudited, have been prepared on a basis consistent with the December 31, 2004 audited consolidated financial statements, and include normal recurring adjustments that, in the opinion of management, are
necessary for the fair presentation of the results of these periods. These unaudited interim consolidated financial statements do not include all of the footnote disclosures required in audited financial statements for the full year and,
accordingly, should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Companys Annual Report on Form 10-K for the year ended December 31, 2004. The consolidated balance sheet
information as of December 31, 2004 included herein was derived from those audited consolidated financial statements. The results of operations for the three and nine months ended September 30, 2005 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 accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ
materially from those estimates.

(c) Revenue Recognition



Centra follows the specific guidelines of the Securities and Exchange Commission (SEC) Staff Accounting Bulletin (SAB) No. 104 (SAB
104), Revenue Recognition in Financial Statements, American Institute of Certified Public Accountants Statement of Position (SOP) No. 97-2, Software Revenue Recognition, and SOP No. 98-9, Modification of SOP 97-2, Software
Revenue Recognition, with Respect to Certain Transactions, and related authoritative literature.



Centra derives its revenues from the sale of software licenses, application service provider (ASP) and hosting services, maintenance (post-contract support) and professional services. Maintenance includes telephone
support, error correction or bug fixes and rights to upgrades and enhancements on a when-and-if available basis. Centra executes contracts that govern the terms and conditions of all software licenses, ASP, hosting, and maintenance arrangements and
other professional 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 SOP No. 98-9. As described below, significant management judgments and estimates must be made and used in connection with the revenue recognized in any accounting period.
Management analyzes various factors, including a review of specific transactions, historical experience, creditworthiness of customers and current market and economic conditions. Changes in judgments based upon these factors could impact the timing
and amount of revenue and cost recognized and thus affect the Companys results of operations and financial condition.



Centra generally licenses its software products on a perpetual basis. Centra applies the provisions of SOP No. 97-2, as amended by SOP No. 98-9, to all
transactions involving the sale of software products. Centra recognizes revenue from the sale of software licenses when persuasive evidence of an arrangement exists, the product has been delivered, the fees are fixed or determinable and collection
of the resulting receivable is reasonably assured. This policy is applicable to all direct sales to end-users. License sales to distributors or to value-added resellers through a distribution agreement are recognized when an end-user customer has
been identified and all other revenue recognition criteria have been met. License sales to U.S. government agencies through teaming arrangements with third-party partners are recognized when a signed order from the partner and evidence of a purchase
order from the government agency to the partner is received and all other revenue recognition criteria have been met. The Company does not offer a right of return on its products.



For all sales, except those to U.S. government agencies as described above, Centra uses a signed master license, distribution or service
agreement, a signed sales order or contract amendment and/or a binding purchase order as evidence of an arrangement. For arrangements with multiple elements (i.e. the sale of a product license along with the sale of maintenance and support, training
and consulting to be delivered later), Centra allocates revenue to each component of the arrangement using the residual value method. Under the residual value method, revenue is recognized in a multiple element arrangement in which vendor-specific
objective evidence (VSOE) of fair value exists for all of the undelivered elements in the arrangement, but does not exist for one or more of the delivered elements in the arrangement. Centra defers revenue from the arrangement equivalent to the fair
value of the undelivered elements and recognizes the remaining amount from the total arrangement fee at the time of the shipment of the last element for which VSOE does not exist, assuming all other revenue recognition criteria have been met. The
VSOE of fair values for professional services, training and other products sold by Centra are based upon prices realized when these services and products are sold separately. VSOE for maintenance and support obligations is based on either historical
renewal rates calculated as a percentage of net discounted license or customer-specific, contractually stated renewal rates for maintenance and support upon expiration of the initial term.



Centra also sells its suite of products and services in a bundled package on a multi-year
subscription basis for broader use by its customers. In the third quarter of 2004, the Company began to offer a bundled package of products and services for an annual fee based on a multi-year purchase commitment of two to three years. The annual
fee, which is typically paid at the beginning of each year, provides for unlimited use of the specified software products within a specific department, division or entity of a corporation or for use by the entire enterprise. The suite of products
and services may include a term license for the software products, ASP or hosting services, maintenance and support, consulting and training. Centra recognizes revenue from these multi-year subscriptions either ratably over the entire length of the
subscription term or over each annual payment term. For classification purposes in the statement of operations, Centra allocates revenue to each of the license, software services, maintenance and professional services based on their relative fair
values supported by VSOE if available or a reasonable estimate of fair value made by management based on the average discount offered on products or services when sold separately. Centras customers may choose to purchase the enterprise-wide
subscription without a term license for the software and instead utilize Centras ASP service over the term of the agreement. Centra recognizes revenue for ASP enterprise-wide subscriptions ratably over the subscription term according to SAB
104. Revenue is allocated for classification purposes to software services and professional services based on their relative fair values supported by verifiable objective evidence.

At the time of entering into a transaction, Centra assesses whether the fee associated with the transaction is fixed or
determinable, including the payment terms associated with the transaction. Standard payment terms granted to customers are from 30 to 90 days. If extended payment terms are granted, Centra recognizes revenue when payments become due and payable.
Centra assesses whether collection is probable based on the creditworthiness of the customer. Initial creditworthiness is assessed through Dun & Bradstreet, similar credit rating agencies or the customers SEC filings. Creditworthiness
for transactions to existing customers is assessed through a review of their prior payment history. Centra does not request collateral from its customers. If the Company determines that collection of a fee is not probable, the Company will defer the
fee and recognize revenue at the time collection becomes probable, which is generally upon the receipt of payment.



Revenues from start-up fees associated with the ASP service are recognized over the estimated life of the ASP relationship. Revenues related to ASP services are
recognized ratably 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 for hosting services are recognized ratably on a straight- line basis over the term that the
hosting services are provided. Also, in instances where Centra hosts a customers purchased software on its server and network, Centra provides the customer a copy of the licensed software in addition to one that is kept on the Centra server
and recognizes the license revenue for the purchased software in accordance with its revenue recognition policy for licensed software as discussed above and in accordance with the Emerging Issues Task Force Issue (EITF) No. 00-3, Application of
SOP 97-2 to Arrangements that Include the Rights to Use Software Stored on Another Entitys Hardware.



Revenues from maintenance and support services are recognized ratably on a straight-line basis over the term that the maintenance service is provided. Revenues from consulting and education services are recognized
either as the services are performed or ratably over a subscription period if bundled as part of a subscription. Generally, consulting and education services, including implementation, are not considered essential to the functionality of
Centras software as these services do not alter the softwares capabilities, do not require specialized skills and may be performed by the customer or other vendors.



Centra records as deferred revenues any billed amounts due from customers in excess of revenues recognized. Deferred revenues consist
principally of license subscriptions, maintenance and support, ASP and hosting services and consulting and education services.



(d) Stock-Based Compensation



The Company grants stock options to its employees and outside directors. Such grants are for a fixed number of shares with an exercise price equal to the fair value of
the shares at the date of grant. The Company accounts for stock-based employee compensation using the intrinsic value method under the recognition and measurement principles of the Accounting Principles Board (APB) Opinion No. 25 (APB 25),
Accounting for Stock Issued to Employees, and related interpretations and has elected the disclosure-only alternative under Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 123 (FAS 123),
Accounting for Stock-Based Compensation, as amended by SFAS No. 148, Accounting for Stock-Based Compensation  Transition and Disclosure  An Amendment of FASB Statement No. 123. The fair value of the Companys
stock options was estimated using the Black-Scholes option-pricing model. This model was developed for use in estimating fair value of traded options that have no vesting restrictions and are fully transferable. This model requires the input of
highly subjective assumptions including the expected stock price volatility. Because the Companys stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions
can materially affect the fair value estimates, in managements opinion, the Black-Scholes model does not necessarily provide a reliable single measure of the fair value of its stock options. The following table illustrates the effect on net
(loss) income and net (loss) income per share on a pro forma basis as if the Company had applied the fair value recognition provisions of FAS 123 to stock-based employee compensation (in thousands, except per share data):

Options to purchase a total of
7,952,000 and 6,580,767 shares of common stock have not been included in the computation of diluted net loss per share for the three and nine months ended September 30, 2004 and for the nine months ended September 30, 2005, respectively,
as these shares are considered antidilutive, due to the net loss during those periods. Options to purchase a total of 3,643,917 shares of common stock have not been included in the computation of diluted net income per share for the three months
ended September 30, 2005 since their exercise prices exceeded the average market price of the common stock during the period.



(h) Recent Accounting Pronouncements



In March 2005, the SEC issued SAB No. 107 (SAB 107), which expresses the view of the staff regarding the interaction between the FASBs FAS 123 and its revision
SFAS No. 123R (FAS 123R), Share-Based Payment, and certain SEC rules and regulations, and provides the staffs views regarding the valuation of share-based payment arrangements for public companies. Specifically, SAB 107 provides
guidance on how to determine the expected volatility and expected term inputs into a valuation model used to determine the fair value of share based payments under FAS 123R. SAB 107 also provides guidance related to numerous aspects of the adoption
of FAS 123R such as taxes, capitalization of compensation costs, modification of share-based payments prior to adoption and the classification of expenses. The Company adopted SAB 107 in the quarter ended March 31, 2005, where guidance relates
to transactions occurring prior to the adoption of FAS 123R. The adoption of SAB 107 did not have a material impact on the Companys consolidated financial statements. The Company has not determined the effect, if any, the guidance provided in
SAB 107 relating to FAS 123R upon adoption will have on the consolidated financial statements.



In April 2005, the SEC adopted a new rule that amends the compliance dates for FAS 123R which is now effective beginning the first annual reporting period that begins after June 15, 2005. FAS 123R allows for two
methods of accounting upon adoption; modified prospective application and the modified retrospective application for all periods presented. The Company has not determined the effect the adoption of FAS 123R will have on the consolidated financial
statements. However, the pro forma disclosure under Stock-Based Compensation above approximates what would have been the impact of applying FAS 123R to the historical periods presented.



In May 2005, the FASB issued SFAS No. 154 (SFAS 154), Accounting Changes and Error
Corrections  A Replacement of APB Opinion No. 20 and FASB Statement No. 3, which requires that a voluntary change in accounting principle be applied retrospectively with all prior period financial statements presented, unless it
is impracticable to do so. SFAS 154 also provides that (1) a change in method of depreciating or amortizing a long-lived nonfinancial asset be accounted for as a change in estimate (prospectively) that was effected by a change in accounting
principle, and (2) correction of errors in previously issued financial statements should be termed a restatement. The new standard is effective for accounting changes and correction of errors made in fiscal years beginning after
December 15, 2005. Early adoption of this standard is permitted for accounting changes and correction of errors made in fiscal years beginning after June 1, 2005. The Companys adoption of SFAS 154 during the three-month period ended
June 30, 2005 did not have any effect on its consolidated financial statements.



In June 2005, the EITF issued No. 05-06, Determining the Amortization Period of Leasehold Improvements or Acquired in a Business Combination(EITF 05-06). EITF 05-06 provides that the amortization period for lease hold
improvements acquired in a business combination or purchased after the inception of a lease be the shorter of (a) the useful life of the assets or (b) a term that includes required lease periods and renewals that are reasonably assured
upon the acquisition of the purchase. The provisions of EITF 05-06 are effective on a prospective basis for leasehold improvements purchased or

acquired beginning July 1, 2005. The Companys adoption of EITF 05-06 during the three-month period ended September 30, 2005 did not have any
effect on its consolidated financial statements.



(2) 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, selling and marketing
of software products and related services, and therefore no segment disclosures are required. Centras revenues based on location of customer, as a percentage, are as follows:



|              |  |                                 |   |  |                                |   |  |      |   |  |      |

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



(3) Significant Customer



No one customer accounted for more than 10% of total revenues during the
three and nine month periods ended September 30, 2004 and 2005. No one customer accounted for more than 10% of accounts receivable at December 31, 2004. One customer equaled 19% of the Companys accounts receivable at
September 30, 2005.



(4) Commitments and Contingencies



Severance



In April 2005, Paul R. Gudonis resigned his position as the Companys president, chief
executive officer and as a member of the board of directors. Centra accrued during the three months ended June 30, 2005, severance compensation and benefits of $473,000 to be paid to Mr. Gudonis in monthly installments totaling $310,000
and $163,000 in 2005 and 2006, respectively.



Stock-Based
Compensation Charge



In 2003 and 2005, Centra entered into severance
agreements with certain senior executives that provide for stock option vesting acceleration upon a change in control of the Company and a 12-month stock option exercise period upon termination of employment (except for cause). The stock options
originally issued to these executives were granted at fair market value and accounted for under APB 25, which did not result in a compensation charge at the time of issuance. The stock options were modified by the severance agreements as the
accelerated vesting or extended exercise feature was not present when the option was originally granted. A compensation charge would result at the time of vesting acceleration, if not previously vested at the time of the change in control, or upon
option exercise, if the exercise date upon termination is outside the original exercise period of 90 days; the amount of the compensation charge would be based on the difference between the closing stock price on the date of modification and the
exercise price of the option. Centra estimates that the maximum potential compensation charge related to the modifications is $110,000.



Securities Class Action Lawsuit



Centra, certain of its former and current officers and directors and the managing underwriters of Centras initial public offering were named as defendants in an
action filed in the United States District Court for the Southern District of New York. The plaintiffs filed an initial complaint on December 6, 2001 and purported to serve the Centra defendants on or about March 18, 2002. The original
complaint has been superseded 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, which is being coordinated with an action
captioned in re Initial Public Offering Securities Litigation, No. 21 MC 92, 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

##### Table of Contents

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. The underwriter defendants and the Centra defendants joined
in motions to dismiss the above-reference action on July 3 and July 15, 2002, respectively. On October 9, 2002, the plaintiffs dismissed, without prejudice, the claims against the named Centra officers and directors in the
above-referenced action. On February 19, 2003, the court issued an order denying the motion to dismiss as to Centra and other defendants. On June 7, 2003, the plaintiffs announced a proposed settlement with all issuers, including Centra.
On June 25, 2004, the plaintiffs filed a motion with the United States District Court for the Southern District of New York requesting preliminary approval of the settlement. The court has given preliminary approval of the settlement. Centra
plans to participate in this settlement, which has been negotiated, and will be fully funded directly to the plaintiffs, by Centras insurers. No amount has been accrued related to this matter and legal costs incurred in the defense of the
matter are being expensed as incurred.



EdiSync Patent Claim



On August 19, 2003, a complaint was filed against the Company and
two other defendants by EdiSync Systems, LLC, in the United States District Court for the District of Colorado (No. 03-D-1587 (OES)). The complaint alleges infringement of two patents for a remote multiple user editing system and method and seeks
permanent injunctive relief against continuing infringement, compensatory damages in an unspecified amount, and interest, costs and expenses associated with the litigation. The Company has filed an answer to the complaint denying all of the
allegations. No amount has been accrued related to this matter and legal costs incurred in the defense of the matter are being expensed as incurred. The Company filed a request for reexamination of the patents at issue with the U.S. Patent and
Trademark Office as patent counsel to the Company is of the opinion that claims of the patents involved in the suit are invalid. The re-examination request was accepted by the Patent Office and the District Court has approved the parties
motion to stay the court proceedings during the re-examination proceedings. The Company believes that it has meritorious defenses and the Company intends to vigorously defend this action.



Employment Claim



On September 3, 2004, a former employee filed a complaint with the Massachusetts Superior Court (civil action no. 04-3479). In this civil action, the former employee
brought claims against the Company and two of its former officers relating to the termination of her employment in November 2003. In particular, this former employees claims include gender, race and age discrimination, retaliation for her
alleged whistle-blowing activity, and breach of a severance agreement. The Company filed a motion to dismiss certain aspects of the case, which motion was denied in June 2005. The case is in pre-trial discovery, which is scheduled to conclude in
early 2006. The Company believes the claims are without merit and is vigorously defending the claims. No trial date has been set.



Severance Agreements



The Company is subject to severance agreements with each of its five executives that provide for up to two years of bonus, base compensation and benefits in the event of
voluntary or non-voluntary termination in certain circumstances and upon or after a change of control. While payments under certain of these agreements are expected to be paid upon consummation of our proposed merger with Saba, management does not
expect that the payments and ultimate costs, if any, related to these agreements will have a material adverse effect on the Companys results of operations, financial position or cash flows.



Software Indemnifications



Centra enters into standard indemnification agreements in the ordinary course of business.
Pursuant to these agreements, Centra indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally Centras business partners or customers, in connection with any
patent, copyright or other intellectual property infringement claim by any third party with respect to its products. The term of these indemnification agreements is generally perpetual. The maximum potential amount of future payments Centra could be
required to make under these indemnification agreements is unlimited. Centra has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. Accordingly, Centra has no liabilities recorded for these
agreements as of September 30, 2005.



Centra warrants that its software
products will perform in all material respects in accordance with its standard published specifications in effect at the time of delivery for 90 days. Additionally, Centra warrants that its maintenance services will be performed consistently with
generally accepted industry standards through completion of the agreed upon services. If

necessary, Centra would provide for the estimated cost of product and service warranties based on specific warranty claims and claim history. However, since
Centra has never incurred any significant expenses under the Companys product or service warranties, it has no liabilities recorded for these agreements as of September 30, 2005.



(5) Restructuring Charges



In June 2004, the Company incurred a restructuring charge of $547,000 related to an 18%
reduction in its worldwide workforce and the closing of the Companys product development facility in Morrisville, North Carolina. The restructuring charge consisted of severance payments, health benefits and outplacement services. In the
quarter ended September 30, 2004, Centra completed the closure of the Morrisville facility resulting in an additional $241,000 restructuring charge, consisting of facility closure costs, and additional severance, health benefits and
outplacement services. The accrued and unpaid amount of these charges at September 30, 2005 was $47,000, which the Company paid out in October 2005. No additional expenses are expected in future periods.



The restructuring accrual activity in the nine months ended September 30, 2005 is
summarized as follows (in thousands):



|                                         |  |                                   |    |          |   |     |                                     |  |   |

(6) Subsequent Event



On October 5, 2005, Centra entered into an Agreement and Plan of
Reorganization with Saba, and two wholly-owned subsidiaries of Saba. Under the merger agreement, holders of Centra common stock will receive 0.354 shares of Saba and $.663 for each share of Centra common stock outstanding at the time of the merger.
The merger is expected to close in the first calendar quarter of 2006 and is subject to certain conditions including approval by Centras stockholders and approval by Sabas stockholders of the issuance of Saba shares in the merger. A
provision in the merger agreement provides that under certain circumstances described in the merger agreement, Centra could be required to pay Saba a termination fee in the amount of $1.8 million.

Forward-Looking Statements



Certain statements contained in this Quarterly Report on Form 10-Q, including information with respect to our future business plans, objectives, expectations and
intentions constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. For this purpose, any statements contained herein that are
not statements of historical fact may be deemed to be forward-looking statements. Without limiting the foregoing, the words believe, plan, expect, anticipate, intend, seek,
estimate, may, will, and continue, or similar words are intended to identify forward-looking statements. You should read statements that contain these words carefully. They discuss our future
expectations, contain projections of our future results of operations or our financial condition or state other forward-looking information, and may involve known and unknown risks over which we have no control. You should not place undue reliance
on forward-looking statements. We cannot guarantee any future results, levels of activity, performance or achievements. Moreover, we assume no obligation to update forward-looking statements or update the reasons actual results could differ
materially from those anticipated in forward-looking statements, except as required by law. The forward-looking statements discussed in the sections captioned Overview, Critical Accounting Policies, Liquidity and
Capital Resources, and Factors That Could Affect Future Results identify important factors that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements.

Except as otherwise expressly stated, forward-looking statements contained in this report assume that we will continue to
operate as an independent company and do not give effect to our proposed merger with Saba Software, Inc. (Saba), described in Item 5 of this Report under Other Information. Consummation of the proposed merger with Saba will cause
our business plans and our results to differ in material respects from those indicated in the forward-looking statements appearing herein.



Overview



We provide software and services for online learning and training. Centra enables groups to work faster and more effectively by automating critical learning and training
initiatives online through virtual classrooms, online meetings and Web conferences. Our customers can use our solutions to deliver hands-on training and support of new software applications, expand training and certification to employees and
external channel partners, and support change management activities. In addition, we offer consulting, education, content creation and support services that enable our customers to successfully implement, deploy and support our products and
solutions throughout their organizations.



Our objective is to improve our
leadership position in the segment of the real-time collaboration market that focuses on online learning and training. We intend to leverage our leadership position to increase the use of our products throughout the enterprise and in other segments
of the collaborative learning market. Also, we intend to focus our sales and marketing efforts on selling to the Global 5000 companies, government agencies and higher education institutions. To achieve these objectives, we are pursuing the following
strategies (although we can give no assurance that these strategies will be successful or that we will be able to achieve profitability as a result of themsee Factors That Could Affect Future Results, below):



| |  |  | Further improve our core technology;
| | - |  | ------------------------------------



| |  |  | Develop add-on modules for our solutions;
| | - |  | -----------------------------------------



| |  |  | Improve and promote our extensive professional and customer services;
| | - |  | ---------------------------------------------------------------------



| |  |  | Offer innovative and flexible pricing options to customers;
| | - |  | -----------------------------------------------------------



| |  |  | Create category awareness by leveraging existing customer usage;
| | - |  | ----------------------------------------------------------------



| |  |  | Leverage our direct field sales force to expand penetration in existing accounts and acquire new enterprise accounts;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Evaluate strategic alternatives; and
| | - |  | ------------------------------------



| |  |  | Expand the ecosystem of alliance, technology, and channel distribution partners.
| | - |  | --------------------------------------------------------------------------------



The market for application software solutions and services for online business communication, collaboration and learning is evolving,
subject to rapid technological change and highly competitive. Our goals of achieving revenue growth and establishing a market leading position are dependent upon various factors, including: 1) delivery of new add-on modules for our solutions; 2)
macroeconomic conditions, 3) corporate IT needs and spending capacity, 4) successful packaging and presentation of our products, 5) efficient and effective execution of our sales, pricing and licensing strategies and 6) competitive entrants and
marketplace actions. (For a more comprehensive analysis of risk factors, see Factors That Could Affect Future Results below.)



We have experienced substantial losses since our inception. As of September 30, 2005, we had an accumulated deficit of $99.2 million. These losses and our
accumulated deficit have resulted from the significant costs incurred in the development, marketing, sale and delivery of our products and services, including the establishment of our hosted and ASP services infrastructure, which have been only
partially offset by our revenues to date. We reduced our operating expenses in 2004 by reducing the number of employees, consolidating development facilities and entering into a lower-cost operating lease for our headquarters. However, we may not be
able to continue to decrease our expenses, increase our revenues or sustain the profitability that we have achieved over the past two quarters for any future periods. We plan to slightly increase revenue in 2005 from 2004 levels and improve
operating margins year over year, which will require us to reduce our operating expenses in 2005 below 2004 levels. 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. See Factors That Could Affect Future Results  We may not successfully execute our strategic plan.

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, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions
or conditions.



Our critical accounting policies are summarized in our Annual
Report on Form 10-K for the year ended December 31, 2004, in the section titled Managements Discussion and Analysis of Financial Condition and Results of Operations under the caption Critical Accounting Policies.
We have reviewed those policies and determined that, except as noted below they remain our critical accounting policies for the nine months ended September 30, 2005.



During the three months ended June 30, 2005, we reviewed our recent history of collecting all amounts within the terms stated in our
sales arrangements with large, well capitalized customers for which we granted extended payment terms ( i.e., beyond 90 days). The recent history of collecting all amounts within the stated terms did not include a sufficient number of transactions
to conclude that such fees were fixed or determinable and thus, we could no longer support the recognition of revenue at the time the product is delivered for transactions with extended payment terms. Accordingly, we have amended our critical
accounting policy for revenue recognition as follows:



At the time of entering
into a transaction, we assess whether the fee associated with the transaction is fixed or determinable, including the payment terms associated with the transaction. Standard payment terms granted to customers are from 30 to 90 days. If extended
payment terms are granted, we recognize revenue when payments become due and payable.



Recently Issued Accounting Standards



In March 2005, the SEC
issued SAB No. 107 (SAB 107), which expresses the view of the staff regarding the interaction between the FASBs SFAS No. 123 (revised 2004) (FAS 123R), Share-Based Payment, and certain SEC rules and regulations and provides
the staffs views regarding the valuation of share-based payment arrangements for public companies. Specifically, SAB 107 provides guidance on how to determine the expected volatility and expected term inputs into a valuation model used to
determine the fair value of share based payments under FAS 123R. SAB 107 also provides guidance related to numerous aspects of the adoption of FAS 123R such as taxes, capitalization of compensation costs, modification of share based payments prior
to adoption and the classification of expenses. We adopted SAB 107 in the quarter ended March 31, 2005, where guidance relates to transactions occurring prior to the adoption of FAS 123R. The adoption of SAB 107 did not have a material impact
on our consolidated financial statements. We have not determined the effect, if any, the guidance provided in SAB 107 relating to FAS 123R upon adoption will have on our consolidated financial statements.



In April 2005, the SEC adopted a new rule that amends the compliance dates for FAS 123R which
is now effective beginning the first annual reporting period that begins after June 15, 2005. FAS 123R allows for two methods of accounting upon adoption; modified prospective application and the modified retrospective application for all
periods presented. We have not determined the effect the adoption of FAS 123R will have on the consolidated financial statements.



In May 2005, the FASB issued SFAS No. 154 (SFAS 154), Accounting Changes and Error Corrections  A Replacement of APB Opinion No. 20 and FASB Statement
No. 3, which requires that a voluntary change in accounting principle be applied retrospectively with all prior period financial statements presented, unless it is impracticable to do so. SFAS 154 also provides that (1) a change in
method of depreciating or amortizing a long-lived nonfinancial asset be accounted for as a change in estimate (prospectively) that was effected by a change in accounting principle, and (2) correction of errors in previously issued financial
statements should be termed a restatement. The new standard is effective for accounting changes and correction of errors made in fiscal years beginning after December 15, 2005. Early adoption of this standard is permitted for accounting changes
and correction of errors made in fiscal years beginning after June 1, 2005. The adoption of SFAS 154 during the three month period ended June 30, 2005 did not have any effect on our consolidated financial statements.



In June, 2005 the Emerging Issues Task Force (EITF) issued No. 05-06, Determining the
Amortization Period of Leasehold Improvements or Acquired in a Business Combination(EITF 05-06). EITF 05-06 provides that the amortization period for lease hold improvements acquired in a business combination or purchased after the inception of
a lease be the shorter of (a) the useful life of the assets or (b) a term that includes required lease periods and renewals that are reasonably assured upon

the acquisition of the purchase. The provisions of EITF 05-06 are effective on a prospective basis for leasehold improvements purchased or acquired beginning
July 1, 2005. The adoption of EITF 05-06 during the three-month period ended September 30, 2005 did not have any effect on our consolidated financial statements.

Comparison of three months ended
September 30, 2004 and 2005



Revenues. Total revenues
decreased by $329,000, or 3%, to $9.4 million for the three months ended September 30, 2005, compared to $9.7 million for the three months ended September 30, 2004. The decrease was attributable to decreases in revenues from software
license and software services sales, partially offset by increases in maintenance and professional services sales.



| |  |  | Software license revenues decreased by $265,000, or 9%, to $2.6 million for the three months ended September 30, 2005, from $2.8 million for the three months ended
September 30, 2004. The decrease was due to reduced license sales in the European and Asian marketplaces. We expect license sales will vary in future periods depending on whether our customers choose to purchase a subscription-based offering or
a perpetual license. Software license revenue represented 27% and 29% of total revenues for the three months ended September 30, 2005 and 2004, respectively.

| |  |  | Software services revenues, which include our ASP and hosting services, decreased by $168,000, or 6%, to $2.5 million for the three months ended September 2005, from $2.7 million
for the three months ended September 2004. The decrease was primarily attributable to a decline in revenue from usage-based contracts during the quarter. Software services revenues represented 27% and 28% of total revenues for the three months ended
September 30, 2005 and 2004, respectively.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Maintenance and professional services revenues, which includes our maintenance and support, consulting and education services, increased by $104,000, or 2%, to $4.3
million for the three months ended September 30, 2005, from $4.2 million for the three months ended September 30, 2004. The increase was primarily due to an increase in the dollar value of renewals of annual maintenance and support
contracts. We believe that maintenance and professional services revenues will continue to be slightly higher in 2005 over 2004 levels as our installed base of license

| | users grows and new maintenance contracts are added. The rate of the increase may vary from period to period, depending primarily upon the value of new
maintenance contracts added and the productivity rates of professional services. Any increases may be offset by non-renewals of maintenance contracts. Maintenance and professional services revenues represented 46% and 43% of total revenues for the
three months ended September 30, 2005 and 2004, respectively.

Cost of license revenue. Our costs of license fees are determined by the royalty costs for third-party software that we integrate or resell with our products, which are both fixed-price and variable based on the amount of products
sold. Cost of license revenues increased by $95,000, or 151%, to $158,000 for the three months ended September 30, 2005, from $63,000 for the three months ended September 30, 2004. The increase was due to a higher portion of fixed-price
royalties for third-party software, including those purchased in December 2004 for our add-on modules to our enterprise-wide solution sets. These fixed-price contracts are being amortized over their contract period. In addition, since a portion of
our license costs represent royalties that we pay to third parties on a per unit rate of product sold, we expect that cost of license revenues will vary in the future based upon the unit volume of products sold and to the extent that we incorporate
additional third-party technologies into our products and solutions. Cost of license revenues was 6% and 2% of license revenues for the three months ended September 30, 2005 and 2004, respectively.



Cost of software services revenues. Our cost of software services revenues includes
(1) salaries and related expenses for our ASP and hosted services organizations, (2) an overhead allocation consisting primarily of that portion of our facilities, communications and depreciation expenses that is attributable to providing
these services, (3) a technical support allocation consisting primarily of a portion of our technical support expenses that is attributable to providing such support to our ASP customer base and (4) direct costs related to our hosting and
ASP service offerings. Cost of software services revenues of $548,000 for the three months ended September 30, 2005 remained relatively flat as compared to $555,000 for the three months ended September 2004. We expect that the cost of software
services revenues will increase in absolute dollars to the extent that we expand the capacity of our ASP and hosting services to meet increased demand. Cost of software services revenues was 22% and 21% of software services revenues for the three
months ended September 30, 2005 and 2004, respectively.



Cost of
maintenance and professional services revenues. Our cost of maintenance and professional services revenues includes salaries and related expenses for our consulting, education and technical support services organizations and an overhead
allocation consisting primarily of that portion of facilities, communications and depreciation expenses that is attributable to providing these services. Cost of maintenance and professional services revenues decreased by $205,000, or 17%, to $1.0
million for the three months ended September 30, 2005 from $1.2 million for the three months ended September 30, 2004. The decrease was primarily related to a decrease in personnel-related expenses due to a decline in professional services
personnel and associated travel expenses and a decrease in employment fees. Cost of maintenance and professional services revenues was 23% and 29% of maintenance and professional services revenues for the three months ended September 30, 2005
and 2004, respectively. We believe that the cost of maintenance and professional services revenue could increase in absolute dollars but decline as a percentage of revenues to the extent that we continue to acquire new customers, new service
engagements or sell additional licenses and generate associated maintenance and professional services revenues.



Sales and marketing expenses. Sales and marketing expenses decreased by $1.7 million, or 36%, to $3.1 million for the three months ended September 30, 2005,
from $4.8 million for the three months ended September 30, 2004. The decrease was primarily attributed to a decrease in personnel-related expenses, due to a decline in sales and marketing personnel and a decrease in marketing programs,
including advertising, Web marketing, product literature and public relations. Sales and marketing expenses were 33% and 49% of total revenues for the three months ended September 30, 2005 and 2004, respectively. We expect sales and marketing
expenses for the fourth quarter to increase as compared to the three months ended September 30, 2005 due to an increase in commission generated from an anticipated increase in sales bookings, as well as increased spending in travel, marketing
programs and annual incentives.



Product development expenses. Product
development expenses decreased by $179,000, or 8%, to $2.1 million for the three months ended September 30, 2005, from $2.3 million for the three months ended September 30, 2004. The decrease was primarily attributed to lower
personnel-related expenses due to the headcount reduction related to the closing of our development facility in North Carolina in September 2004. Product development expenses were 23% and 24% of total revenues for the three months ended
September 30, 2005 and 2004, respectively. We expect product development expenses for the fourth quarter to remain relatively flat compared to the three months ended September 30, 2005.



General and administrative expenses. General and administrative expenses decreased by
$605,000, or 25%, to $1.8 million for the three months ended September 30, 2005, from $2.4 million in the quarter ended September 30, 2004. The decrease was due to (1) the absence of a severance charge in the third quarter of 2005
that was present in the third quarter of 2004 related to the departure of our former president and chief operating officer, (2) a reduction in personnel-related costs due to a decline in general and administrative personnel, (3) a decline
in audit expenses due to reduced expenses incurred in the

second year of compliance with Section 404 of the Sarbanes Oxley Act of 2002 as compared to the first year and (4) a reduction in ongoing
business-related legal costs. These declines were offset by $310,000 in external legal and financial due diligence expenses incurred during the quarter for merger-related activities. General and administrative expenses were 19% and 25% of total
revenues for the three months ended September 30, 2005 and 2004, respectively. We expect general and administrative expenses for the fourth quarter to increase as compared to the three months ended September 30, 2005 due to higher
merger-related costs expected to be incurred as compared to the third quarter.



Restructuring charges. We did not record any restructuring charge during the quarter ended September 30, 2005. During the quarter ended September 30, 2004, we incurred restructuring charges of $241,000 related to the
closing of our product development facility located in Morrisville, North Carolina and the subsequent workforce reduction, primarily product development personnel related thereto, along with a worldwide workforce reduction that mostly affected sales
and marketing and general and administrative personnel.



Interest
income. Interest income increased by $104,000, or 118%, to $192,000 for the three months ended September 30, 2005, from $88,000 for the three months ended September 30, 2004. Interest income consists primarily of interest on our cash,
cash equivalents and short-term investments. The increase reflects an increase in short-term interest rates during the current quarter compared with the same period last year.



Interest expense and other expense, net. Interest expense and other expense was $28,000 and $10,000 for the three months ended
September 30, 2005 and 2004, respectively.



Comparison of nine
months ended September 30, 2004 and 2005



Revenues. Total
revenues increased by $1.1 million, or 4%, to $28.7 million for the nine months ended September 30, 2005, from $27.6 million for the nine months ended September 30, 2004. The increase was primarily the result of an increase in maintenance
and professional services and software services revenues, partially offset by a decrease in software license revenues.



| |  |  | Software license revenue decreased by $318,000, or 4%, to $7.7 million for the nine months ended September 30, 2005, from $8.0 million for the nine months ended
September 30, 2004. The decrease was due to decreased sales in the Asia Pacific marketplace offset by increases in European and domestic sales. Software license revenue represented 27% and 29% of total revenues for the nine months ended
September 30, 2005 and 2004, respectively.

million for the nine months ended September 30, 2004. The increase resulted from higher hosting services revenues and higher ASP subscription revenues, primarily reflecting the new multi-year enterprise ASP subscription contracts introduced in
the second half of 2004. Software services revenues represented 27% and 28% of total revenues for the nine months ended September 30, 2005 and 2004, respectively.

for the nine months ended September 30, 2005, from $12.0 million for the nine months ended September 30, 2004. The increase was due to increases in the dollar value of renewals of annual maintenance and support contracts and higher
consulting and education services revenues attributable to longer client engagements resulting in improved productivity rates of our consulting personnel. Maintenance and professional services revenues represented 46% and 43% of total revenues for
the nine months ended September 30, 2005 and 2004, respectively.

Cost of license revenue. Our costs of license fees are determined by the royalty costs for third-party software that we integrate or resell with our products, which are both fixed-price and variable based on the amount of products
sold. Cost of license revenues increased by $221,000, or 114%, to $415,000 for the nine months ended September 30, 2005, from $194,000 for the nine months ended September 30, 2004. The increase was due to higher fixed royalty costs from
third-party software, including those purchased in December 2004 for our add-on modules to our enterprise-wide solution sets. These fixed-price contracts are being amortized over their contract period. Cost of license revenues was 5% and 2% of
license revenues for the nine months ended September 30, 2005 and 2004, respectively.



Amortization of acquired developed technology. In connection with our acquisition of MindLever in April 2001, we allocated approximately $2.1 million to acquired developed technology, which was being amortized
over a three-year estimated useful life. Amortization of acquired developed technology was $233,000 for the nine months ended September 30, 2004. As the asset has been fully amortized, no amortization charge was incurred in the nine months
ended September 30, 2005 and no further amortization costs will be incurred.

Cost of software services revenues. Cost of software services revenues decreased by $110,000, or 6%, to $1.7
million for the nine months ended September 30, 2005, from $1.8 million for the nine months ended September 30, 2004. The decrease was primarily due to a reduction in personnel-related expenses due to lower headcount and to lower Internet
Service Provider expenses. Cost of software services revenues was 21% and 23% of software services revenues for the nine months ended September 30, 2005 and 2004, respectively.



Cost of maintenance and professional services revenues. Cost of maintenance and professional services revenues was $3.3 million for
the nine months ended September 30, 2005 and 2004. Cost of maintenance and professional services revenues was 25% and 27% of maintenance and professional services revenues for the nine months ended September 30, 2005 and 2004,
respectively.



Sales and marketing expenses. Sales and marketing
expenses decreased by $6.3 million, or 38%, to $10.5 million for the nine months ended September 30, 2005, from $16.8 million for the nine months ended September 30, 2004. The decrease was primarily attributed to (1) a decrease in
marketing programs, including advertising, Web marketing, product literature, public relations and tradeshows, (2) a decrease in personnel-related expenses, due to a decline in sales and marketing personnel, (3) a decrease in bonus and
commissions due to a decline in contract bookings and (4) a decrease in the amount of expenses allocated from the professional services organization based on a decline in the amount of time spent supporting sales. Sales and marketing expenses
were 37% and 61% of total revenues for the nine months ended September 30, 2005 and 2004, respectively.



Product development expenses. Product development expenses decreased by $1.2 million, or 15%, to $6.7 million for the nine months ended September 30, 2005, from $7.9 million for the nine months ended
September 30, 2004. The decrease was primarily attributed to lower personnel-related expenses due to the headcount reduction related to the closing of our development facility in North Carolina in September 2004. Product development expenses
were 23% and 28% of total revenues for the nine months ended September 30, 2005 and 2004, respectively.



General and administrative expenses. General and administrative expenses were $6.6 million for the nine months ended September 30, 2005 and 2004. General and administrative expenses were 23% and 24% of
total revenues for the nine months ended September 30, 2005 and 2004, respectively.



Restructuring charges. We did not record any restructuring charge during the nine months ended September 30, 2005. During the nine months ended September 30, 2004, we incurred restructuring charges of
$788,000 related to the closing of our product development facility located in Morrisville, North Carolina and the subsequent workforce reduction, primarily product development personnel related thereto, along with a worldwide workforce reduction
that mostly affected sales and marketing and general and administrative personnel.



Interest income. Interest income increased by $207,000, or 76%, to $480,000 for the nine months ended September 30, 2005, from $273,000 for the nine months ended September 30, 2004. Interest income consists of interest on
our cash, cash equivalents and short- and long-term investments. The increase reflects an increase in interest rates which was partially offset by declines in the balances of cash, cash equivalents and short and long-term investments held during the
period compared with the same period last year.



Interest expense and other
expense, net. Interest expense and other expense, net decreased by $35,000 to $86,000 for the nine months ended September 30, 2005, from $121,000 for the nine months ended September 30, 2004. The decrease was due to a decrease in
foreign exchange losses and interest expense due to a decrease in the balances outstanding on our long-term debt.



Liquidity and Capital Resources



As of September 30, 2005, we had cash and cash equivalents of $21.9 million and short-term investments of $2.6 million, an increase of $10.1 million of cash and cash
equivalents from $11.8 million at December 31, 2004, and a decrease of $11.4 million of short- and long-term investments from $14.1 million as of December 31, 2004. The combined decrease of $1.3 million for cash, cash equivalents and
short- and long-term investments for the nine months ended September 30, 2005 resulted primarily from $1.1 million in cash used in operations. Our working capital, defined as our current assets less our current liabilities, as of
September 30, 2005 was $14.0 million, compared to $12.6 million as of December 31, 2004.



Cash used in operating activities was $1.1 million for the nine months ended September 30, 2005, primarily the result of a decrease in deferred revenue of $1.9 million, a decrease in accrued expenses of $822,000,
an increase in prepaid expenses and other current assets of $610,000 and a decrease in accounts payable of $558,000 offset by a decrease in accounts receivable of $2.1 million and non-cash charges for depreciation of $704,000. For the nine months
ended September 30, 2004, our operating activities used net cash of $7.5 million, primarily resulting from a net loss of $9.8 million, a $584,000

decrease in accrued expenses, a $262,000 increase in prepaid expenses and other current assets, principally insurance partially offset by a decrease in
accounts receivable of $2.2 million and non-cash expenses of $1.3 million.



Cash provided by investing activities was $11.3 million for the nine months ended September 30, 2005, consisting of maturities of short-term investments of $15.5 million, offset by purchases of short-term investments of $4.1 million
and the purchase of $396,000 of property and equipment, primarily computer equipment to support our current operations. For the nine months ended September 30, 2004, our investing activities provided $5.8 million of net cash, primarily
resulting from maturities of marketable securities of $45.1 million offset by purchases of short-term marketable securities of $38.1 million and purchases of $1.0 million of property and equipment to support operations.



Cash used in financing activities was $50,000 for the nine months ended September 30,
2005, resulting primarily from $887,000 in principal payments made on our equipment line of credit/term loan facility offset by $468,000 in proceeds from the issuance of shares of common stock in connection with purchases through our employee stock
purchase program and the exercise of stock options and $369,000 in drawings on our existing line of credit. For the nine months ended September 30, 2004, financing activities provided net cash of $487,000, primarily related to $1.4 million in
proceeds from our equipment line of credit and $667,000 of receipts from the issuance of common stock under the employee stock purchase plan or from the exercise of stock options during the period, offset by $1.6 million in principal payments made
on our line of credit.



Days sales outstanding, or DSO (calculated as net
accounts receivable divided by revenue per day for the previous 90 days), at September 30, 2005 was 55 days, a decrease of 13 days compared to DSO of 68 days at December 31, 2004. The decrease resulted from a decrease in billings during
the third quarter of 2005 and the timing of license sales during the current quarter as compared with the quarter ended December 31, 2004. Any increase or decrease in our accounts receivable balance will affect our cash flow from operations and
liquidity. Our accounts receivable and DSO may increase due to changes in factors such as the timing of when sales are invoiced and the length of our customers payment cycle. We also record deferred ASP and hosted services, maintenance and
professional services billings as accounts receivable, and thus the timing of these billings can affect the DSO calculation as the receivable may be recorded in the current period with the associated revenue recorded over future periods resulting in
an increase in the DSO for the current period. Historically, international customers and resellers pay at a slower rate than domestic customers and customers sold to directly. An increase in revenue generated from international customers and
resellers may increase our DSO and accounts receivable balance. To the extent that our accounts receivable balance increases, we may incur increased bad debt expense and will be subject to greater general credit risks.



At September 30, 2005, $1.5 million in term loans under our current amended equipment
line of credit was outstanding as compared to $2.1 million outstanding at December 31, 2004. Of the total outstanding, $921,000, $250,000, $181,000 and $95,000 are payable in monthly principal payments of approximately $38,000, $8,000, $7,000
and $3,000 plus interest maturing in September 2007, June 2008, December 2007 and September 2008, respectively. Interest is payable monthly based on the prime rate (6.75% at September 30, 2005) plus 0.5%. The remaining outstanding
amount of $96,000 represents two separate loan advances, and is payable in fixed monthly payments of principal and interest of $9,000 and $8,000 maturing at different times through June 2006 with interest rates of 4.75% The current amended equipment
line of credit requires us to maintain a minimum balance of cash, cash equivalents and investments of $10 million and maintain all of our cash, cash equivalents and investments in operating, deposit and investment accounts at the bank. At
September 30, 2005, approximately $508,000 remained available for borrowings under the current line of credit, which may be drawn until March 2006. Substantially all of our assets are pledged as security for the borrowings. At
September 30, 2005, we were in compliance with the covenants under the equipment line of credit.



Capital expenditures totaled $396,000 and $1.0 million for the nine months ended September 30, 2005 and 2004, respectively. Our capital expenditures consisted of purchases of assets to manage our internal
operations and our ASP service, 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 in 2005 to decline from 2004 levels. Since inception, we have generally funded capital expenditures either through the use of working capital or with equipment bank loans.



Over the past two years, in response to business challenges and economic conditions, we have made considerable efforts to reduce our
operating expenses through constrained spending and reductions in workforce. This has resulted in a decrease in our cash used in operations; however, as of September 30, 2005 we still used more cash to operate our business than we generated in
revenues. As discussed above, we anticipate that our overall operating expenses in 2005 will decline as compared to 2004. We anticipate that such operating expenses, along with capital expenditures, will constitute the most significant use of our
cash resources. If we have the opportunity, we may also use cash resources to fund acquisitions or investments in complementary businesses, technologies, products or services. We believe that our existing cash, cash equivalents and short-term and
long-term investments, which totaled $24.5 million at September 30, 2005, will be sufficient

to meet our anticipated cash requirements for operating expenses, capital expenditures and any strategic efforts for at least the next 12 months. However,
thereafter we may need to raise additional funds to support our operations, particularly if our strategic sales and marketing efforts do not produce the desired results. We might also need to seek additional financing if we were to identify a
strategic opportunity that required more cash than we had available at such time. If we did seek to raise additional funds, though, we may not be able to obtain them on terms that are favorable or acceptable to us. See Factors That Could
Affect Future ResultsWe may require additional funds in this Item 2.



Commitments and Contingencies



As of September 30, 2005,
our primary financial commitments consisted of obligations outstanding under long-term debt, operating leases and other contractual obligations. In our Annual Report on Form 10-K for the year ended December 31, 2004, we included under the
heading Commitments and Contingencies a table setting forth our commitments and contingencies as of that date.



Factors That Could Affect Future Results



An investment in our common stock involves a high degree of risk. You should carefully consider the following risk factors in evaluating our business. If any of the
events described below were to actually occur, then our business, financial condition or results of operations could be seriously harmed and the trading price of our common stock could decline. There is no assurance that we will be able to implement
our operating plans as anticipated or achieve projected revenue and earnings goals.



Important factors that could cause our actual results to differ from the forward-looking statements described above include, but are not limited to, the factors outlined below.



Risks Related to the Proposed Merger with Saba



Failure to complete the merger with Saba could damage our financial condition and our business.



If the merger with Saba is not completed for any reason, we will be subject to a number of
material risks, including:



| |  |  | a provision in the merger agreement provides that under certain circumstances, we could be required to pay Saba a termination fee in the amount of $1.8 million;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we will have to pay certain costs related to the merger, such as legal, financial due diligence and accounting fees and a portion of the investment banking fees, even if the merger
is not completed;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | benefits that we expect to realize from the merger would not be realized; and
| | - |  | -----------------------------------------------------------------------------



| |  |  | the diversion of management attention from our day-to-day business and the disruption to our employees and our relationships with customers and suppliers during the period before
the expected consummation of the merger could damage our competitive position and our business.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



During the pendency of the merger, we may not be able to enter into a merger or business combination with another party that might be advantageous to us, because of restrictions in the merger agreement.



Covenants in the merger agreement may impede our ability to make
acquisitions or complete other transactions outside the ordinary course of business pending completion of the merger. As a result, if the merger is not consummated, we may be at a disadvantage to our competitors. In addition, while the merger
agreement is in effect and subject to narrowly defined exceptions, we are prohibited from entering into certain extraordinary transactions, such as a merger, sale of assets or other business combination outside the ordinary course of business with
any third party. As a result, we might be prevented from entering into transactions which might otherwise have been favorable to our stockholders.



We may lose key personnel, customers and business partners due to uncertainties associated with the merger.



Pending the closing of the merger, our current and prospective employees, customers and
business partners may experience uncertainty about their future relationships with the resulting combined company. Such uncertainty may adversely affect our ability to attract and retain key management, sales, marketing and technical personnel.
Current and prospective customers and business partners may, in response to the announcement of the merger agreement, delay or cancel purchasing decisions. Any delay in, or cancellation of, purchasing decisions could adversely affect our business
and results of operations.

##### Table of Contents

Our partners or customers may react unfavorably to the proposed combination.



We are party to certain relationships, and may seek to enter other relationships, with
numerous other technology companies, including software and services firms, to acquire rights to technology included in our products and service and to deliver our products and services to customers. Some of these partners may conclude that the
proposed merger poses new competitive threats to their businesses and as a result may discontinue their relationships with us. In addition, some of our customers may view Saba as a competitor to them and, therefore, terminate their relationships
with us.



Other Risks



We may not successfully execute our strategic plan.



Our strategic initiatives include enhancing our products, improving our services, and
continuing to develop and beginning to sell add-on modules for our solutions. We also intend to continue to evaluate the evolving market for application software solutions and services for online business communication, collaboration and learning
and assess any strategic alternatives that we identify. We can give no assurance as to whether and when we will successfully implement our new strategy of developing and selling solutions. If we are not successful in achieving our strategic
objectives, then our liquidity and working capital will be materially diminished and the value of our stockholders investments could decline significantly.



Our cost cutting efforts could impede our ability to successfully execute our sales strategy.



We believe that the success of our sales strategy of selling application software and
services for online business communication, collaboration and learning, including our new add-on modules, will depend upon our ability to develop new channel partnerships, enhance our relationships with existing customers, expand international
operations, implement new initiatives that improve sales execution and consistency and attract new customers with targeted messaging, print advertising, public relations efforts and lead generation marketing programs. We intended to increase our
sales and marketing expenditures to meet these goals but subsequently delayed our planned increases in sales and marketing expense until such time that our new add-on modules for our solutions begin to achieve market acceptance and we see
significant annual revenue growth. We also implemented other initiatives aimed at reducing our costs. While we believe that our cost-cutting decisions, including our delay in increasing sales and marketing expenses, to be sound, they could impede
our ability to successfully execute our sales strategy.



We have incurred
substantial losses in the past and may not achieve profitability in the future.



We incurred net losses of $11.1 million for the year ended December 31, 2004 and $17,000 for the nine months ended September 30, 2005. Although we recorded a profit of $795,000 for the three months ended September 30, 2005,
we cannot predict if we will be able to continue to be profitable, and if we do, we may not remain profitable for any substantial period of time. If we fail to achieve and maintain profitability, then our investors expectations may not be met
and the market price of our common stock may fall.



Our future success
depends to a significant degree on our senior management team and our ability to retain key employees.



A number of significant changes to our senior management team have occurred, including; the departure of our former chief executive officer and our former chief financial officer, the hiring of our Chairman and
founder as CEO and promotion of our new chief financial officer in the second quarter of 2005 and the departure of and hiring of senior sales, marketing and professional services executives in 2004. Our future success will depend in part on our
ability to carry out the transition in senior management and to integrate the new employees and positions into our operations as well as on the efforts of our other senior managers. Changes in our management team, the inability of our executive
officers and key employees to work effectively as a team or the inability to retain key employees could have a material adverse effect on our business, operating results and financial condition.



The success of our strategy depends on our ability to license and integrate third-party
technology to enhance our products.



Our ability to enhance our solutions
and the add-on modules to them is dependent upon our ability to license, under commercially reasonable terms, third-party software that enhances, enables or provides additional functionality for them. If we are not able to successfully license
third-party software to incorporate into our products, we may not be able to timely deliver future versions of our solutions. In addition, the third-party software that we intend to license may or may not continue to be available on commercially
reasonable terms or with acceptable levels of support or functionality, or at all. Failure to obtain or maintain these license arrangements, failure of the third-party vendors to provide updates, modifications



22



---

##### Table of Contents

or future versions of their software or defects and errors in, or infringement claims against those third-party products could delay or impair our ability to
develop and sell our products and execute against our strategic plan.



Delays in sales could cause significant variability in our revenues and operating results for any particular period.



We generally need to educate potential customers regarding the benefits of our conferencing, collaboration and learning products and services before they will commit to
the purchase of our products. Our sales cycle varies depending on the size and type of customer contemplating a purchase, the complexity of the customers purchasing process and whether we have conducted business with the customer in the past.
Both new and existing customers frequently need to obtain approvals from multiple decision makers within their organization prior to making purchase decisions. We expect that the sales cycle will continue to be characterized by these features as we
move towards selling broader enterprise-based solutions and larger, multi-year contracts.



We face significant competition from other technology companies and we may not be able to compete effectively.



The markets for conferencing, collaboration and learning products and services are highly competitive. We expect that our competition in this market will intensify in the
future, which will likely result in price reductions, reduced gross margins and loss of market share, any one of which could seriously harm our business. Competitors vary in size and in the scope and breadth of the products and services offered. We
encounter competition with respect to different aspects of our online business communication, collaboration and learning solutions from a variety of software and services vendors. In addition, larger companies with more resources than we have could
enter our market and either reduce our sales or require us to lower our prices, or both.



Some of our competitors have longer operating histories and significantly greater financial, technical, marketing and other resources than we do. Some have significantly greater name recognition and a larger installed
base of customers. In addition, many of our competitors have well-established relationships with our current and potential customers. In the past, we have lost potential customers to competitors for various reasons, including lower prices and other
incentives not matched by us. In addition, current and potential competitors have established or may establish cooperative relationships among themselves or with third parties to increase the ability of their products to address customer needs.
Accordingly, it is possible that new competitors or alliances among competitors may emerge and rapidly acquire significant market share.



We may lose customers or incur losses if we experience system failures that significantly disrupt the availability and quality of our hosted and ASP services.



While our products can be deployed at a customers premises or on
its network as a packaged software application, we also deliver our products as an ASP or hosted service utilizing our network. Our hosted services and ASP services depend on the efficient and continued operation of our internal and outsourced
computer and communications hardware and software systems and our ability to avoid and mitigate any interruptions in service or reduced capacity. Some of our communications hardware and software is hosted at third-party facilities. These third-party
providers are vulnerable to business and economic uncertainties as well as damage or interruption from human error, telecommunications failures, computer viruses, sabotage, and intentional acts of vandalism, all of which may affect their ability to
continue to provide services. Interruptions in service or performance problems, for whatever reason, could undermine confidence in our services and cause us to lose customers or make it more difficult to attract new ones. In addition, any
significant interruption in our service could result in losses to our customers. Although we attempt contractually to disclaim liability for any such losses, a court might not enforce a limitation on our liability, which could expose us to financial
loss.



We may require additional funds.



We expect that our current cash, cash equivalents and short-term investments will be
adequate to provide us with sufficient working capital for at least the next 12 months. However, our current plans and projections may prove to be inaccurate or our expected cash flow may prove to be insufficient to fund our operations because of
difficulties in executing our sales and marketing strategy, demand for our new products, delays in developing new products and improvements, unanticipated expenses or other unforeseen difficulties. Therefore, we may need to raise additional capital
to continue to fund our operations, particularly if our strategic sales and marketing efforts do not produce the desired results. We might also need to seek additional financing if we were to identify a strategic opportunity or desirable technology
to acquire that required more cash than we had available at the time.



Our
ability to obtain any additional financing that may be needed will depend on a number of factors, including market conditions, our operating performance and investor interest, particularly in software companies providing online business
communication, collaboration and learning solutions. These factors may make the timing, amount, terms and conditions of any financing unattractive. They may also result in our incurring additional indebtedness or accepting stockholder dilution. If



23

##### Table of Contents

adequate funds are not available or are not available on acceptable terms, we may have to forego strategic acquisitions or investments, defer our product
development activities, or delay our continued rollout of new products and product versions. Any of these actions may seriously harm our business and operating results.



Our future success will depend on our ability to respond effectively to technological changes and new industry standards and developments
in new versions of our products.



As with any software technology, we
expect that the demand and product specifications continue to change and therefore our future success will depend in large part on our ability to stay current with any technology shifts and meet the evolving needs of the market by timely
introduction of new products or product releases. In the past, we have experienced delays in the introduction of new products. In addition, our product enhancements must meet the requirements of our current and prospective customers and must achieve
significant market acceptance. We could also incur substantial costs if we need to modify our products, services or information technology infrastructure to adapt to these changes, standards and developments.



The market price of our common stock has been and may continue to be volatile.



Our stock price, like that of other technology companies, has been
extremely volatile. The announcement of new products, services, technological innovations, customers or distribution partners by us or our competitors, quarterly variations in our operating results, changes in revenues or earnings estimates by
securities analysts, speculation in the press or investment community and overall economic conditions are among the factors affecting our stock price.



In addition, the stock market in general and the market prices for technology companies in particular, have experienced extreme volatility that often has been unrelated
to the operating performance of these companies. These broad market and industry fluctuations may adversely affect the market price of our common stock, regardless of our operating performance. Recently, when the market price of a stock has been
volatile, holders of that stock have often instituted securities class action litigation against the company that issued the stock. If any of our stockholders brought a lawsuit against us, we could incur substantial costs defending the lawsuit. The
lawsuit could also divert the time and attention of our management away from operating our business.



The general economic uncertainties in the United States and abroad continue to cause significant volatility in the stock markets. The continued threat of terrorism in the United States and abroad, the ongoing military
action and heightened security measures undertaken in response to that threat can be expected to cause continued volatility in securities markets. In addition, foreign political unrest may continue to adversely affect the economy.



Our business could be adversely affected by the existence of bugs or errors in our current
or future product versions.



Software products as complex as ours may
contain errors or bugs that result in product failures. From time to time, we have identified errors in our products after their commercial introduction. While we have not been materially harmed by errors in our products in the past, errors or bugs
in our current or future products that we are not able to correct at all or correct in a timely fashion may cause our revenues to decline.



Claims by other companies that we infringe their proprietary technology could force us to redesign our products or otherwise hurt our financial condition.



If we were to discover that any of our products violated third-party
proprietary rights, there can be no assurance that we would be able to reengineer the product or obtain a license on commercially reasonable terms, or at all, that would enable us to continue offering the product without substantial reengineering.
Also, our product license agreement states that we will indemnify our customers for any of their costs as a result of our infringement on others technology, if any. Such costs could be substantial. We do not conduct comprehensive patent
searches to determine whether the technology used in our products infringes patents held by third parties. In addition, product development is inherently uncertain in a rapidly developing technology environment in which there may be numerous patent
applications pending, many of which are confidential when filed, with regard to similar technologies. Any claim of infringement could cause us to incur substantial costs defending against the claim, even if the claim is invalid, and could distract
our management from our business. Furthermore, a party making such a claim could secure a judgment that requires us to pay substantial damages. A judgment could also include an injunction or other court order that could prevent us from selling our
products or cause our customers to stop using our products. On August 19, 2003, EdiSync Systems, LLC filed a complaint against us in federal court in Denver, Colorado, alleging infringement of two patents for a remote multiple user editing
system and method and seeking to enjoin us from continuing to sell our products, as well as unspecified compensatory damages. Although we believe we have meritorious defenses and intend to vigorously defend this action, we can give no assurance that
we will be able to achieve a satisfactory outcome. See Legal Proceedings.

Future regulations could be enacted that either directly restrict our business or indirectly impact our business by
limiting the growth of Internet-based business and services.



As
commercial use of the Internet increases, federal, state and foreign agencies could enact laws or adopt regulations covering issues such as user privacy, content, taxation of products and services, encryption, network and information security, and
the convergence of telephone and other traditional communication services with Internet communications such as Voice-Over-Internet-Protocol. If enacted, such laws or regulations could limit the market for our products and services. Any
inconsistencies between state, federal and non-U.S. laws and regulations could affect distribution of our products and/or increase our costs. Such legislation or regulation could also dampen the growth in Web usage and decrease its acceptance as a
medium of communications and commerce.



We face business risks relating to
our international operations.



Our success is focused on sales to
multinational corporations, which requires us to have international operations and incur risks associated with those operations. In addition to our North American operations, we have established sales, marketing and service operations in Europe and
Australia and we sell through distributors and resellers in a number of countries around the world. We cannot be sure that our international operations will be successful. Our international operations require resources and managements
attention beyond what is required for our domestic operations and subjects us to additional regulatory, economic and political risks, including:



| |  |  | longer payment cycles and problems in collecting accounts receivable;
| | - |  | ---------------------------------------------------------------------



| |  |  | adverse changes in trade and tax regulations;
| | - |  | ---------------------------------------------



| |  |  | the absence or significant lack of legal protection for intellectual property rights;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | the adoption of data privacy or other laws or regulations that restrict or regulate the use of our products or the Internet;

We cannot assure our investors that we will be able to manage these risks effectively or that our international efforts will be successful.



Our success depends on our ability to protect our proprietary rights.



Our success depends to a significant degree upon the protection of our software and other
proprietary technology. If we fail to protect our proprietary rights, other companies might use our technology to introduce competing products or services that compete with ours, without paying us for our technology. This could have a material
adverse effect on our business, operating results and financial condition. Our proprietary technology and intellectual property includes one pending U.S. patent application, which has not yet been approved, and the Centra®trademark, among others. We depend upon a combination of patent and trademark laws, license
agreements, non-disclosure and other contractual provisions to protect proprietary and distribution rights of our products. In addition, we attempt to protect our proprietary information and those of our vendors and partners through confidentiality
and license agreements with our employees and others. Although we have taken steps to protect our proprietary technology, they may be inadequate. Existing trade secret, copyright and trademark laws offer only limited protection. Moreover, the laws
of other countries in which we market our products may afford little or no effective protection of our intellectual property. If we resorted to legal proceedings to enforce our intellectual property rights, the proceedings could be burdensome and
expensive, even if we were to prevail.

If we identify and report material weaknesses in our internal controls over financial reporting as required by
Section 404 of the Sarbanes-Oxley Act of 2002, investors could lose confidence in the reliability of our financial statements, which could result in a decrease in the value of our common stock.



As directed by Section 404 of the Sarbanes-Oxley Act of 2002, the Securities and
Exchange Commission adopted rules requiring public companies to include in their Annual Reports on Form 10-K a report of management on our internal control over financial reporting, including managements assessment of the effectiveness of the
companys internal control over financial reporting as of the companys year end. In addition, the independent public accounting firm auditing a public companys financial statements must also attest to and report on managements
assessment of the effectiveness of the companys internal control over financial reporting as well as the operating effectiveness of the companys internal controls. Our independent public accounting firm has provided a report on
managements assessment of internal controls for financial reporting and the effectiveness of internal controls over financial reporting in which they expressed an opinion that we maintained in all material respects effective internal controls
and financial reporting as of December 31, 2004. However, if in future periods it is determined that our internal controls are not designed or operating effectively as required by Section 404 or our independent public accounting firm 1)
disclaims an opinion as it relates to managements assessment of the effectiveness of its internal controls; 2) issues a qualified opinion on the effectiveness of the companys internal controls or 3) renders an adverse opinion due to
material weaknesses in our internal controls, then investors may lose confidence in the reliability of our financial statements, which could cause the market price of our common stock to decline.



We could incur substantial costs resulting from product liability claims relating to our
customers use of our products and services.



Many of the business
interactions supported by our products and services are critical to our customers businesses. Any failure in a customers business interaction or other collaborative activity caused or allegedly caused by our products and services could
result in a claim for substantial damages against us, regardless of our responsibility for the failure. Although



we maintain general liability insurance, including coverage for errors and omissions, and contractually attempt to limit liability, there can be no assurance that our
existing coverage will continue to be available on reasonable terms or will be available in amounts sufficient to cover one or more large claims, or that the insurer will not disclaim coverage as to any future claim.



Certain provisions of our charter and of Delaware law make a takeover of our company more
difficult.



Our corporate documents and Delaware law contain provisions
that might enable our management to resist a takeover of our company. These provisions, including our stockholder rights plan, might discourage, delay or prevent a change in our control or a change in our management. These provisions could also
discourage proxy contests and make it more difficult for you and other stockholders to elect directors and take other corporate actions. The existence of these provisions could limit the price that investors might be willing to pay in the future for
shares of our common stock. Additionally, we have entered into agreements with certain employees and executive officers, which, among other things, include certain severance and change of control provisions.



|Item 3. | Quantitative and Qualitative Disclosures about Market Risk
|------- | ----------------------------------------------------------



We are exposed to market risk related to foreign currency exchange rates and to changes in interest rates. We do not use derivative financial instruments for speculative
or trading purposes.



Foreign Currency



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. International sales are typically denominated in Euros, British pounds, Australian dollars or in U.S. dollars.
Since some of our sales internationally are currently priced in U.S. dollars; a strengthening of the dollar could make our products less competitive in foreign markets. In the nine months ended September 30, 2005 and 2004, we generated
approximately 23% and 18% of our revenues outside of the United States, respectively. Our foreign subsidiaries incur most of their expenses in the local currency. Accordingly, all foreign subsidiaries use the local currency as their functional
currency. Translation gains and losses are accumulated as a separate component of stockholders equity (accumulated other comprehensive loss) in the consolidated balance sheets. Gains and losses resulting from foreign exchange transactions are
netted and included in other expense, net, in the accompanying consolidated statements of operations. A 10% change in the valuation of the functional currencies relative to the U.S. dollar as of September 30, 2005 would not have a material
impact on our results of operations for the nine months ended September 30, 2005.

Interest Rates



We maintain an investment portfolio consisting mainly of fixed rate U.S. government-backed federal agency notes and highly liquid money
market instruments, with an average maturity of less than 12 months, in accordance with our investment policy approved by our board of directors. Our general investment policy is to limit the risk of principal loss and seeks to ensure the safety of
invested funds by limiting market and credit risk. We currently use a registered investment manager to place our investments, which are typically held to maturity. These investments are denominated in U.S. dollars. Cash balances in foreign
currencies overseas are operating balances and are only invested in short-term deposits of the local operating bank. All highly liquid investments with original maturities of three months or less are considered to be cash equivalents.



Investments in fixed rate interest earning financial instruments are subject to interest rate
risk and will decrease in value if market interest rates were to increase. However, due to the conservative nature of our investment portfolio, a sudden change in interest rates would not have a material effect on the fair value of the portfolio. If
market interest rates were to decline, the interest earned on our investment portfolio would decrease. We estimate that if the average yield of our investments had decreased by 100 basis points, our interest income for the nine months ended
September 30, 2005 would have decreased by less than $202,000. This estimate assumes that the decrease occurred on the first day of the year and reduced the yield of each investment instrument by 100 basis points. The impact on our future
interest income and future changes in investment yields will largely depend on the gross amount of our portfolio.



Certain of the long-term debt instruments require interest payments calculated at variable interest rates. If interest rates were to increase, the interest payments on
those long-term debt instruments would also increase. The effect of any such increase in interest expense would be partially offset by any resulting increase in interest income from our investment portfolio.



|Item 4. | Controls and Procedures
|------- | -----------------------



As required under the Sarbanes-Oxley Act of 2002, our chief executive officer and chief financial officer conducted a review of our disclosure controls and procedures (as
defined in Exchange Act Rules 13a-14(e) and 15d-14(e)) in connection with the preparation of this report. Based on such evaluation, our chief executive officer and our chief financial officer have concluded that our disclosure controls and
procedures, as of the end of the period covered by this report, were adequate and effective to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded,
processed, summarized and reported, within the time periods specified in the Commissions rules and forms.



There were no changes in our internal control over financial reporting identified in connection with the above-referenced evaluation that occurred during the fiscal
quarter covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.



PART II. FINANCIAL INFORMATION



|Item 1. | Legal Proceedings
|------- | -----------------



From time to time, we have been, and expect to continue to be, subject to legal proceedings and claims in the ordinary course of our business. Such claims, even if not meritorious, could result in the expenditure of
significant financial and managerial resources. Except for the lawsuits identified below in this section, we are not presently a party to any legal proceedings, the adverse outcome of which, in managements opinion, would have a material
adverse effect on our results of operations or financial position.



Securities Class Action Lawsuit



We and certain of our former
and current officers and directors and the managing underwriters of our initial public offering were named as defendants in an action filed in the United States District Court for the Southern District of New York. The plaintiffs filed an initial
complaint on December 6, 2001 and purported to serve us on or about March 18, 2002. The original complaint has been superseded by an amended complaint filed in April 2002. The action, captioned in re Centra Software, Inc. Initial Public
Offering Securities Litigation, No. 01 CV 10988, which is being coordinated with an action captioned in re Initial Public Offering Securities Litigation, No. 21 MC 92, is purportedly brought on behalf of the class of persons who purchased
our 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 our 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 our 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 us and the named
individuals. We joined in motions with the underwriter defendants to dismiss the above-referenced action on July 3 and July 15, 2002, respectively. On October 9, 2002, the plaintiffs dismissed, without prejudice, the claims against
our officers and directors in the above-referenced action. On February 19, 2003, the court issued an order denying the motion to dismiss as to the other defendants and us. On September 7, 2003, the plaintiffs announced a proposed
settlement with all issuers, including us. On September 25, 2004, the plaintiffs filed a motion with the United States District Court for the Southern District of New York requesting preliminary approval of the settlement. The court has given
preliminary approval of the settlement. We plan to participate in this settlement, which has been negotiated, and will be fully funded directly to the plaintiffs, by our insurers. No amount has been accrued related to this matter and legal costs
incurred in the defense of the matter are being expensed as incurred.



EdiSync Patent Claim



On August 19, 2003, a complaint was
filed against us and two other defendants by EdiSync Systems, LLC, in the United States District Court for the District of Colorado (No. 03-D-1587 (OES)). The complaint alleges infringement of two patents for a remote multiple user editing system
and method and seeks permanent injunctive relief against continuing infringement, compensatory damages in an unspecified amount, and interest, costs and expenses associated with the litigation. We filed an answer to the complaint denying all of the
allegations. No amount has been accrued related to this matter and legal costs incurred in the defense of the matter are being expensed as incurred. We filed a request for reexamination of the patents at issue with the U.S. Patent and Trademark
Office as our patent counsel is of the opinion that claims of the patents involved in the suit are invalid. The re-examination request was accepted by the Patent Office and the District Court has approved the parties motion to stay the court
proceedings during the re-examination proceedings. We believe that we have meritorious defenses and we intend to vigorously defend this action.



Employment Claim



On September 3, 2004, a former employee filed a complaint with the Massachusetts Superior Court (civil action no. 04-3479). In this civil action, the former employee
brought claims against us and two of our former officers relating to the termination of her employment in November 2003. In particular, this former employees claims include gender, race and age discrimination, retaliation for her alleged
whistle-blowing activity, and breach of a severance agreement. We filed a motion to dismiss certain aspects of the case, which was denied in September 2005. The case is in pre-trial discovery, which is scheduled to conclude in early 2006. We believe
the claims are without merit and are vigorously defending the claims. No trial date has been set.



|Item 4. | Submission of Matters to a Vote of Security Holders
|------- | ---------------------------------------------------



We held our annual meeting of stockholders on July 14, 2005. Two substantive matters were submitted to a vote of the security holders: (1) the election of two
Class III Directors to serve until the 2008 annual meeting and (2) a proposal to ratify the appointment of our independent registered public accounting firm, PricewaterhouseCoopers LLP. As of May 20, 2005, the record date for the meeting,
there were outstanding 27,891,564 shares of common stock entitled to vote at the meeting. At the meeting, 25,378,178 shares were represented in person or by proxy. At the meeting, the vote with respect to each substantive matter proposed to the
stockholders was as follows:

|Item 5. | Other Information
|------- | -----------------



On October 5, 2005, we entered into an agreement and plan of reorganization with Saba Software, Inc. (Saba), a Delaware corporation, Spruce
Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of Saba, and

##### Table of Contents

Spruce Acquisition, LLC, a Delaware limited liability company and a wholly-owned subsidiary of Saba. Pursuant to the merger agreement, Spruce Acquisition
Corporation will merge with and into us, and we will be the surviving corporation in this first step merger. Immediately afterwards we will merge with and into Spruce Acquisition, LLC, with Spruce Acquisition, LLC as the surviving company in this
second step merger. Our board of directors and the board of directors of Saba have unanimously approved the merger agreement and the mergers.



Under the terms of the merger agreement, each outstanding share of our common stock will be converted into the right to receive 0.354 shares of Sabas common stock
and $0.663 in cash. The mergers are subject to customary conditions to closing, including approval of our stockholders and the stockholders of Saba. The closing of the mergers is expected to occur during the first quarter of 2006. The mergers are
intended to qualify as a tax-free reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended.
