PROXY STATEMENT
ANNUAL MEETING OF STOCKHOLDERS
to be held on February 20, 2001

This Proxy Statement is being furnished in connection with the solicitation by and on behalf of the Board of Directors of Transaction Systems Architects, Inc. (the "Company" or "TSA") of proxies to be used at the Annual Meeting of Stockholders of the Company (the "Annual Meeting") to be held on February 20, 2001, and any postponement or adjournment thereof. A copy of the Company's Annual Report to Stockholders, including the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2000, which includes the Company's financial statements as of and for the year ended September 30, 2000, accompanies this Proxy Statement. Stockholders may obtain a copy of the Company's Annual Report on Form 10-K and a list of the exhibits thereto without charge by written request to Investor Relations, 224 South 108th Avenue, Omaha, Nebraska 68154. This Proxy Statement and the accompanying form of proxy are being mailed to holders of the Company's Class A Common Stock and this Proxy Statement and the accompanying form of voting instruction card are being mailed to holders of TSA Exchangeco Limited's Exchangeable Shares on or about January 19, 2001.

Proxy Solicitation

The shares of the Company's Class A Common Stock, $.005 par value ("Common Stock") represented by the proxies received pursuant to this solicitation and not revoked will be voted at the Annual Meeting. A holder of Common Stock ("Common Stockholder") who has given a proxy may revoke it prior to its exercise by giving written notice of revocation to the Secretary of the Company or by giving a duly executed proxy bearing a later date. Attendance in person at the Annual Meeting does not itself revoke a proxy; however, any Common Stockholder who does attend the Annual Meeting may revoke a proxy previously submitted by voting in person. Subject to any such revocation, all Common Stock represented by properly executed proxies will be voted in accordance with specifications on the proxy. If no such specifications are made, proxies will be voted FOR the election of the six nominees for director listed in this Proxy Statement, FOR approval of the amendment to the Transaction Systems Architects, Inc. 1999 Stock Option Plan, FOR approval of the amendment to the Transaction Systems Architects, Inc. Employee Stock Purchase Plan, FOR ratification of the appointment of Arthur Andersen LLP as the Company's independent auditors for the September 30, 2001 fiscal year, and, as to any other matter that may be brought before the Annual Meeting, in accordance with the judgment of the person or persons voting the same.

Common Stockholders whose shares of Common Stock are registered directly with the Company's transfer agent, Wells Fargo Bank Minnesota, National Association, may vote electronically via the Internet or telephone. Such Common Stockholders should refer to the enclosed form of proxy for instructions on voting via the Internet or telephone. The Internet voting facilities for Common Stockholders of record will close at 12:00 p.m. Omaha time on February 19, 2001, and the telephone voting facilities for Common Stockholders of record will close at 11:00 a.m. Omaha time on February 19, 2001. Common Stockholders whose shares are registered in the name of a broker or bank should refer to the information forwarded by the broker or bank to determine if Internet or telephone voting is available to them.

Exchangeable Shares of TSA Exchangeco Limited, a Nova Scotia limited company and subsidiary of the Company ("Exchangeable Shares"), are designed to have economic rights equivalent to the Common Stock, and they can be exchanged on a one-for-one basis into shares of Common Stock. The

Exchangeable Shares were issued pursuant to the Company's acquisition of MessagingDirect Ltd. Holders of Exchangeable Shares ("Exchangeable Shareholders") may vote at the meeting by instructing Wells Fargo Bank Minnesota, National Association, the Trustee of the Trust created for the benefit of Exchangeable Shareholders, how to vote their Exchangeable Shares. Pursuant to the terms of the Trust, the Trustee holds a share of Special Preferred Voting Stock of the Company that entitles it to cast the number of votes equal to the number of Exchangeable Shares outstanding voting as a single class with the Common Stock. Pursuant to the terms of the trust, however, the Trustee will only vote, or grant proxies to vote, pursuant to the instructions of the Exchangeable Shareholders and will not vote, or grant proxies to vote, with respect to any Exchangeable Shares for which it has not received instructions from the Exchangeable Shareholder. An Exchangeable Shareholder may also instruct the Trustee to give a proxy to a person designated by the Exchangeable Shareholder, to grant a proxy to a designated representative of the management of the Company, or to grant a proxy to the Exchangeable Shareholder so that the Exchangeable Shareholder may attend the meeting and vote in person. Such proxies granted by the Trustee to a representative of management will only be voted with respect to the election of directors, amendment of the 1999 Stock Option Plan, amendment of the 1999 Employee Stock Purchase Plan, and appointment of the independent auditors in accordance with the instructions of the holders of the Exchangeable Shares as to such matters. As to any other matter that may come before the Annual Meeting, such proxies will authorize the person or persons voting the same to vote in accordance with their judgment. An Exchangeable Shareholder may revoke or amend instructions to the Trustee by giving written notice of revocation to the Trustee or by giving duly executed instructions bearing a later date. In order for instructions or revocations to be binding on the Trustee, they must be received by the Trustee no later than the close of business on February 16, 2001. Exchangeable Shareholders who are personally present at the Annual Meeting and submit identification satisfactory to the Trustee's representative at the meeting, and who either submits a written revocation of any previous instructions or have not previously given the Trustee instructions, may also receive a proxy from the Trustee to vote personally at the meeting. Exchangeable Shareholders should use the accompanying form of voting instruction card to instruct the Trustee.

The Company will bear the expense of preparing, printing and mailing this Proxy Statement and proxies solicited hereby, and will reimburse banks, brokerage firms and nominees for their reasonable expenses in forwarding solicitation materials to beneficial owners of shares held of record by such banks, brokerage firms and nominees. The Company has retained Wells Fargo Bank Minnesota, National Association, to assist in the solicitation of proxies at a cost of approximately $20,000 plus normal out-of-pocket expenses.

Outstanding Shares and Voting Rights

Only stockholders of record at the close of business on January 11, 2001 (the "Record Date") are entitled to notice of and to vote at the Annual Meeting. At the close of business on the Record Date, there were 34,937,171 shares of Common Stock, issued and outstanding, excluding 1,476,145 shares of Common Stock held as treasury stock by the Company and 1,410,942 Exchangeable Shares issued and outstanding. The shares of Common Stock held as treasury stock are not entitled to be voted. Each holder of a share of Common Stock or an Exchangeable Share is entitled to one vote per share for the election of directors and on all other matters to be voted on by the Company's stockholders. Holders of Common Stock or Exchangeable Shares may not cumulate their votes in the election of directors. Unless the context requires otherwise, all references to "shares" or "stockholders" in this Proxy Statement and at the Annual Meeting include all shares of Common Stock and all Exchangeable Shares entitled to vote at the Meeting and the holders thereof.

The presence in person or by proxy at the Annual Meeting of the holders of a majority of the issued and outstanding shares shall constitute a quorum. Election of a director requires affirmative votes of the holders of a plurality of the shares present in person, or represented by proxy, at a meeting (at which a

quorum is present). Therefore, the six persons receiving the greatest number of votes shall be elected as directors. Since only affirmative votes count for this purpose, withheld votes will not affect the outcome, except that they will count in determining the presence of a quorum.

With respect to the amendment to the 1999 Stock Option Plan and the amendment to the 1999 Employee Stock Purchase Plan and ratification of the appointment of independent auditors, a stockholder may mark the accompanying form of proxy or voting instruction card to (i) vote for the matter, (ii) vote against the matter or (iii) abstain from voting on the matter. Assuming that a quorum is present at the Annual Meeting, the affirmative vote of a majority of the shares represented at the Annual Meeting and entitled to vote on the matter is required for approval of the amendment to the 1999 Stock Option Plan and the amendment to the 1999 Employee Stock Purchase Plan, and the affirmative vote of a majority of the shares represented at the Meeting and voting on the matter is required for ratification of the appointment of independent auditors. Proxies or voting instruction cards marked to abstain from voting with respect to the amendment to either the 1999 Stock Option Plan or the amendment to the 1999 Employee Stock Purchase Plan will have the legal effect of voting against such matter, and with respect to the ratification of independent auditors will have the effect of being represented for quorum purposes but not voted. The shares represented by broker proxies which are not voted with respect to the amendment to the 1999 Stock Option Plan, the amendment to the 1999 Employee Purchase Plan, or the ratification of the appointment of independent auditors will be considered represented at the Meeting and entitled to vote only as to those matters actually voted. The Exchangeable Shares represented by proxies granted by the Trustee to a representative of management which are not voted with respect to the election of directors, the amendment to the 1999 Stock Option Plan, the amendment to the 1999 Employee Stock Purchase Plan, or the ratification of the appointment of independent auditors will be considered represented at the Meeting and entitled to vote only as to those matters actually voted.

The Board of Directors has nominated the following persons, each of whom is currently serving as a director, for election as directors to serve until the 2002 Annual Meeting of Stockholders and thereafter until their respective successors are duly elected and qualified. The Company expects that each of the nominees will be available for election, but if any of them is not a candidate at the time the election occurs, it is intended that such proxy will be voted for the election of another nominee to be designated by the Board of Directors to fill any such vacancy.

Information Regarding the Board and its Committees

Each non-employee Director receives a $3,125 fee per quarter for his services. Mr. Fisher does not receive any compensation for his services as a director. All directors are reimbursed for expenses incurred in connection with attendance at Board of Director and committee meetings.

During fiscal 2000, there were four meetings of the Board of Directors. Each incumbent director who was a member of the Board of Directors during fiscal year 2000 attended all of the meetings except Messrs. Kever and Noell, each of whom attended three of the four board meetings, and Mr. Duman attended one of the two meetings since his appointment to the Board of Directors.

Each of Messrs. Kever and Fendley were granted a stock option for 20,000 shares of Common Stock upon their respective appointments to the Board of Directors in November 1996. These options were granted under the Transaction Systems Architects, Inc. 1996 Stock Option Plan at an exercise price of $33.25 per share, which was the market price of the Common Stock on that day. Mr. Alexander was granted a stock option for 20,000 shares of Common Stock upon his appointment to the Board of Directors in February 2000. Mr. Noell was granted a stock option for 20,000 shares of Common Stock in January 2000. These options were granted to Messrs. Alexander and Noell under the Transaction Systems Architects, Inc. 1996 Stock Option Plan at exercise prices of $25.938 and $23.375 per share, respectively, which were the market prices of the Common Stock on the respective grant dates. Additionally, each of Messrs. Kever, Fendley, Alexander, and Noell receive options for 4,000 additional shares of Common Stock on the anniversary of their respective elections to the Board except for Mr. Noell, who receives options for 4,000 additional shares of Common Stock on the anniversary of his initial grant of 20,000 shares of Common Stock in January 2000, in each of the four succeeding years so long as they remain a member of the Board of Directors on such anniversary dates. Accordingly, in November 1997, 1998, 1999, and 2000, each of Messrs. Kever and Fendley were granted stock options for 4,000 shares of Common Stock at an exercise price per share of $39.125 for options granted in 1997, $36.375 for options granted in 1998, $31.9375 for options granted in 1999, and $13.875 for options granted in 2000, and in January 2001, Mr. Noell was granted a stock option for 4,000 shares of Common Stock at an exercise price of $11.8125 per share. Vesting of these options is 20% per year at the end of each of five years. Mr. Duman declined receipt of any options which would have otherwise been granted to him under the Transaction Systems Architects, Inc. 1996 Stock Option Plan, and in lieu thereof received an amendment to prior stock option agreements to permit all of his previously-granted options to purchase a total of 58,000 shares to continue to vest and to extend the exercise period for such options notwithstanding Mr. Duman's resignation as an employee of the Company, such extension being subject to Mr. Duman's continuing to serve as a director of the Company. On May 5, 2000, at an exercise price of $16.688 per share, each of Messrs. Kever, Fendley, Alexander, and Noell were granted an option for 6,250 shares of Common Stock from the Transaction Systems Architects, Inc. 2000 Non-employee Director Stock Option Plan, said Plan having been approved by the Company's Board of Directors in May 2000 and under which a total of 25,000 shares of Common Stock are authorized.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange Act") and the rules of the Securities and Exchange Commission (the "Commission") require the Company's directors, certain officers, and beneficial owners of more than ten percent of the Common Stock to file reports of their ownership and changes in ownership of Common Stock with the Commission. Personnel of the Company generally prepare these reports on behalf of its executive officers on the basis of information obtained from them and review the forms submitted to the Company by its non-employee directors and beneficial owners of more than ten percent of the Common Stock. Based on such information, the Company believes that all reports required by Section 16(a) of the Exchange Act to be filed by its directors and officers during or with respect to the last fiscal year were filed on time, except that David C. Russell, Jim D. Kever, Larry G. Fendley, Charles E. Noell, III, and Roger K. Alexander each failed to timely file a Form 5 to report one transaction. Messrs. Russell, Kever, Fendley, Noell, and Alexander each subsequently filed appropriate forms.

(1): The Company's executive officers are eligible for quarterly cash bonuses. Such bonuses are generally based upon achievement of corporate, geographic or product performance objectives including sales, pretax profit, backlog, and cash flow.
(2): Includes incremental amounts paid by the Company for personal use of the Company Airplane.
(3): Includes options granted from the Company's 1999, 1996, and 1994 Stock Option Plans.
(4): Includes contributions made to the Company's retirement plans. For fiscal 2000, employer contributions to the Company's 401(k) Retirement Plan were $4,000 each for Messrs. Fisher, Russell, Parkinson, Mangold, and Vipond.
(5): Each of Messrs. Fisher, Russell, Parkinson, Mangold, and Vipond, and certain other executive officers are a party to an agreement pursuant to which each has agreed not to compete with the Company for so long as he or she is a stockholder of the Company. At the election of the Company, the non-compete agreement may remain in effect for two years after termination of employment (even if he or she is no longer a stockholder) if the Company pays him or her for two years. No amounts were paid in fiscal 2000 under this arrangement.

(1): The options referred to in this table were granted under the Company's 1994, 1996, and 1999 Stock Option Plans. Vesting of the options granted under the 1999 Stock Option Plan occurs on an annual pro rata basis over a term of three years from the date of grant. Vesting of options granted under the 1994 and 1996 Plans occurs on a monthly and annual pro rata basis over a term of 48 months from the grant date, respectively.
(2): Grant date present value is determined using a modified Black-Scholes option-pricing model. The estimated values under the model are based on several assumptions, including a weighted-average expected volatility of 38%, a weighted-average risk-free rate of return of 6.2%, no dividend yield and expected option lives of 6.0 years and may not be indicative of actual value. The actual gain, if any, the option holder may realize will equal the excess of the actual market price of the stock on the date the option is exercised over the exercise price. There is no assurance that the value that may be realized by the option holder will be at or near the value estimated by the modified Black-Scholes model.

(1): None of the options are "In-the-Money" options at the end of the last fiscal year, since the fair market value (closing bid price per the NASDAQ National Market) of the Common Stock at the end of the last fiscal year ($16.313 per share on September 29, 2000) did not exceed the exercise price of the options.

Contemplated Stock Option Exchange Offer

Presently, the vast majority of TSA's outstanding employee stock options have exercise prices greater than the current market price of TSA Common Stock. Stock options have been a significant component of employee compensation at TSA as at many other technology companies. To address the diminution in the value of TSA's outstanding employee stock options due to the decline in market value of the Company's Common Stock and the resulting adverse impact on employee incentive, TSA is contemplating making the following opportunity available to employees who hold options under the Company's 1994, 1996, and 1999 Stock Option Plans ("Existing Options"). The employees would be given the opportunity to exchange Existing Options for replacement options ("Replacement Options") to purchase the same number of common shares as under the Existing Options. The Replacement Options would be issued six months and one day after the effective date of the exchange ("New Grant Date"), provided that on the New Grant Date the person is eligible to receive options under the terms of the applicable stock option plan, which generally requires employment with the Company at the time of grant. The exercise price on the Replacement Options would be the closing bid price for TSA Common Stock on the New Grant Date. It is presently contemplated that most of the Replacement Options would become exercisable at a rate of ¹/18th of the underlying shares after each month commencing with the New Grant Date, which is a faster rate than the Existing Options. All Existing Options exchanged by the holders would be cancelled. Each Replacement Option would be issued under the same option plan as the Existing Option for which it is exchanged. Under the terms of the Company's 1994, 1996, and 1999 Stock Option Plans, the number of shares underlying cancelled Existing Options would become available for issuance of options under the plans as if the cancelled Existing Options had never been granted. The number of shares underlying cancelled Existing Options would be reserved for issuance under the Replacement Options to be granted to the previous holder of the Existing Options. Accordingly, none of the shares that are the subject of the proposal to increase the number of shares for which options may be granted under the 1999 Stock Option Plan would be used in the exchange offer and instead would be available for additional new grants. See, "Approval of Amendment to the 1999 Stock Option Plan." Certain highly compensated employees of the Company who have recently been granted options by the Company and all directors of the Company would be ineligible to participate in the contemplated exchange offer. The Company's intent is that the contemplated exchange offer would not be a repricing for purposes of FASB Interpretation No. 44 and that the granting of the Replacement Options would generate no compensation expense. THIS IS NOT AN OFFER TO ANY OPTION HOLDERS. IF THE COMPANY MAKES THE PRESENTLY CONTEMPLATED EXCHANGE OFFER, IT WOULD BE MADE

THROUGH AN EXCHANGE OFFER STATEMENT AND WOULD BE SUBJECT TO THE TERMS AND CONDITIONS SET FORTH IN THE EXCHANGE OFFER STATEMENT. ELIGIBLE OPTION HOLDERS SHOULD READ THE EXCHANGE OFFER STATEMENT WHEN IT IS AVAILABLE BECAUSE IT WOULD CONTAIN IMPORTANT INFORMATION. ELIGIBLE OPTION HOLDERS WOULD BE PROVIDED THE EXCHANGE OFFER STATEMENT BY THE COMPANY AND IT WOULD ALSO BE AVAILABLE FOR FREE ON THE WEBSITE OF THE SECURITIES AND EXCHANGE COMMISSION AT WWW.SEC.GOV.

Severance Compensation Agreements

The Company has entered into Severance Compensation Agreements (the "Agreements") with 9 of its executive officers, including each of the Named Executive Officers, and 8 other employees. Generally, the Agreements provide that if there is a Change in Control (as defined in the Agreements) of the Company and the employee's employment with the Company is subsequently terminated within two years after the Change in Control other than as a result of death, Retirement (as defined in the Agreements), termination by the Company for Cause (as defined in the Agreements), or the employee's decision to terminate employment other than for Good Reason (as defined in the Agreements), the employee will be entitled to receive from the Company certain payments and benefits. These payments and benefits include (i) a lump-sum payment (the "Severance Amount") equal to, in the case of Messrs. Fisher and Russell, and Douglas Parr and David P. Stokes, two times the average Compensation (as defined in the Agreements) of the employee during the two most recent fiscal years of the Company ending prior to the Date of Termination (as defined in the Agreements), or in the case of the other executive officers (including Messrs. Mangold, Vipond, and Parkinson) and employees who entered into Severance Compensation Agreements with the Company, one times the average Compensation of the employee during the two most recent fiscal years of the Company ending prior to the Date of Termination; (ii) earned but unpaid base salary through the Date of Termination; (iii) a quarterly incentive award for the current fiscal quarter prorated through the Date of Termination equal to the greater of the quarterly incentive award made to the employee for the most recent fiscal quarter ending prior to the Date of Termination or the average quarterly incentive award made to the employee for the most recent three fiscal years ending prior to the Date of Termination; (iv) interest on the amounts described in (i), (ii) and (iii); and (v) unless the employee's termination of employment is the result of the employee's Disability (as defined in the Agreements), continued participation at the Company's cost in employee benefit plans available to Company employees generally in which the employee was participating, until the earlier of receiving equivalent benefits from a subsequent employer or two years from the Date of Termination.

For purposes of determining the Severance Amount referred to above, compensation generally includes compensation includable in the gross income of the employee, but excluding amounts realized on the exercise of non-qualified stock options, amounts realized from the sale of stock acquired under an incentive stock option or an employee stock purchase plan, and compensation deferrals made pursuant to any plan or arrangement maintained by the Company. In no event will the Severance Amount be less than two times the employee's annual rate of base salary at the higher of the annual rate in effect (i) immediately prior to the Date of Termination or (ii) on the date six months prior to the Date of Termination.

Under the Agreements, in the event of a Change in Control, unvested awards and benefits (other than stock options or awards) allocated to the employee under Incentive Plans shall fully vest and become payable in cash.

The Agreements provide that in the event any payment by the Company would be subject to the excise tax imposed by Section 4999 of the Code, or any interest or penalties are incurred by the employee with respect to such excise tax, then the employee will be entitled to an additional payment in an amount such that, after payment by the employee of all taxes, the employee is in the same after-tax position as if no excise tax had been imposed.

Under the Agreements, the Company agrees to indemnify the employee to the fullest extent permitted by law if the employee is a party or threatened to be made a party to any action, suit or proceeding in which the employee is involved by reason of the fact that the employee is or was a director or officer of the Company, by reason of any action taken by him or of any action on his part while acting as director or officer of the Company, or by reason of the fact that he is or was serving at the request of the Company as a director, officer, employee or agent of another enterprise. The Company also agrees to obtain and maintain a directors' and officers' liability insurance policy covering the employee.

The Agreements terminate upon the earlier of (i) termination of employment for any reason prior to a Change in Control and (ii) three years after the date of a Change in Control.

For a complete copy of the Severance Agreements, see Exhibit 10.32 to the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 1999.

CEO's Employment Agreement and Loan

Subsequent to fiscal 2000, the Company reached an agreement with Mr. Fisher, the Company's Chief Executive Officer ("CEO"), on an employment and incentive compensation package (the "Compensation Package"). The Compensation Package provides an annual base salary of $200,000 per fiscal year and for the company to loan Mr. Fisher a total of $3,000,000. The loan bears interest at 6.35% and is due in the first quarter of 2004. The loan and accrued interest are subject to forgiveness in the event of certain changes in control, death, or termination without cause; one-half of the principal and interest is subject to forgiveness if Mr. Fisher remains employed with the Company for the three-year term of the Compensation Package, and one-half of the principal and interest is subject to forgiveness in the event the closing bid for the Company's Common Stock reaches certain price targets. As of September 30, 2000, the Company had advanced Mr. Fisher $2,000,000. Subsequent to September 30, 2000, the Company advanced Mr. Fisher the remaining $1,000,000. No compensation expense related to the Compensation Package was recorded in fiscal 2000.

Certain Transactions

The Company and KFS Management, Inc. are parties to agreements pursuant to which KFS Management, Inc. leased two aircraft to the Company on a non-exclusive basis for business use by the Company. The lease agreements terminated on December 31, 1999. Mr. Fisher and his brother-in-law are the sole stockholders of KFS Management, Inc. During fiscal 2000, the Company paid KFS Management, Inc. a total of $65,000 under the leases agreements. During fiscal 2000, the Company also reimbursed KFS Management, Inc. a total of $8,507 for aircraft-related supplies and the services of its employees.

REPORT OF THE AUDIT COMMITTEE

The Company has a standing Audit Committee (the "Audit Committee") of the Board of Directors. The Audit Committee consists of Messrs. Fendley, Kever and Noell, who are independent (as defined in Rule 4200(a)(14) of the National Association of Securities Dealers' listing standards). The Audit Committee operates pursuant to a charter (the "Audit Committee Charter") approved and adopted by the Board. The Audit Committee Charter is attached as Exhibit A. The Audit Committee, on behalf of the Board, oversees the Company's financial reporting process. In fulfilling its oversight responsibilities, the Audit Committee reviewed with management the audited financial statements and the footnotes thereto in the Company's fiscal 2000 Annual Report to Shareholders and discussed with management the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of the disclosures in the financial statements. The Audit Committee held two meetings in fiscal 2000.

The Company's outside independent public accountants, Arthur Andersen LLP, are responsible for expressing an opinion on the conformity of the Company's audited financial statements, in all material respects, to accounting principles generally accepted in the United States. The Audit Committee reviewed and discussed with the independent public accountants their judgments as to the quality, not just the acceptability, of the Company's accounting principles and such other matters as are required to be discussed by the Audit Committee with the Company's independent public accountants under Statement on Auditing Standards 90. The Company's independent public accountants have expressed the opinion that the Company's audited financial statements conform, in all material respects, to accounting principles generally accepted in the United States. The independent public accountants have full and free access to the Audit Committee.

The Audit Committee discussed with the Company's independent public accountants their independence from management and the Company, and received from them the written disclosures and the letter concerning the independent public accountants' independence required by the Independence Standards Board Standard No. 1.

The Audit Committee discussed with the Company's independent public accountants the overall scope and plans for their audit. The Audit Committee met with the independent public accountants to discuss the results of their audit, their evaluations of the Company's internal controls and the overall quality of the Company's financial reporting.

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in the Annual Report on Form 10-K for the year ended September 30, 2000, for filing with the Securities and Exchange Commission. The Audit Committee also recommended to the Board of Directors the selection of Arthur Andersen LLP to serve as the Company's independent public accountants for fiscal 2001.

REPORT OF THE COMPENSATION COMMITTEE

The Company has a standing Compensation Committee (the "Compensation Committee") of the Board of Directors. The Compensation Committee consists of Messrs. Alexander, Kever, and Noell. All issues relating to executive officer compensation are addressed by the Compensation Committee. The Compensation Committee approves base salary and incentive compensation for all executive officers. During fiscal 2000, the Compensation Committee held one meeting.

The components of the Company's executive compensation program consist of base salaries and annual incentive plans. The Company's compensation program is intended to provide executive officers with overall levels of compensation opportunity that are competitive within the software and computer services industries, as well as within a broader spectrum of companies of comparable size and complexity. The Company's compensation program is structured and administered to support the Company's business mission and generate favorable returns for its stockholders.

Base Salary. Each executive officer's base salary, except for Mr. Fisher's salary, is based on the recommendation of Mr. Fisher to the Compensation Committee. Such recommendations are derived primarily through a comparison of industry and competitive labor markets for executive officer services from surveys conducted by Culpepper and Associates, Inc. ("Culpepper"). In comparison to those surveys, base salaries recommended are slightly lower than the average of other comparably- sized software companies. Other factors in formulating base salary recommendations include the level of an executive's compensation in relation to other executives in the Company with the same, more and less responsibilities, the performance of the particular executive's business unit or department in relation to established strategic plans, the Company's operating budget for the year and the overall performance of the Company.

Incentive Compensation Plan. For each executive officer, an incentive compensation plan is established at the beginning of each fiscal year in connection with the Company's strategic plans and annual operating budgets. Mr. Fisher provides recommendations to the Compensation Committee for incentive compensation for each executive officer, exclusive of himself. The level of incentive compensation recommended for each executive officer is derived through a comparison of industry and competitive labor markets from surveys conducted by Culpepper. In comparison to those surveys, the incentive compensation recommended approximates the average of other comparably-sized software companies. Under these incentive compensation plans, an executive's potential incentive payment is related to the Company's profit attainment, ending backlog, cash flow, and/or the financial performance of an executive's division or department. Because the Company's profit, backlog, cash flow, and divisional financial performance, all being substantial factors in the calculation of incentive compensation, did not meet the Company's expectations in fiscal 2000, bonuses for each of the Company's Named Executive Officers did not meet target levels for fiscal 2000.

CEO Compensation. Compensation for Mr. Fisher, who, exclusive of the period between November 1999 and May 2000, served as the Company's Chief Executive Officer during fiscal 2000, was based on the same criteria used for executive officers generally, as described above. In addition to his base salary, in fiscal 2000 Mr. Fisher was eligible to earn 50% of his base salary if the Company attained 100% of its targets. As compared to industry surveys conducted by Culpepper, Mr. Fisher's base salary was approximately 64% lower than the average and his incentive compensation target for fiscal 2000 was approximately 76% lower than the average. Mr. Fisher's actual combined earnings for fiscal 2000 were approximately 69% less than the average. His maximum possible bonus for fiscal 2000 was 75% of his base salary if the Company exceeded its targets. For fiscal 2000, the Company did not achieve 100% of its targets and Mr. Fisher earned as a bonus 35% of his base salary.

In May 2000, Mr. Fisher returned to the office of CEO after having resigned the position in November 1999. The Compensation Committee then began discussions with Mr. Fisher to reach an agreement

to secure his continued services as the Company's CEO to ensure the Company's leadership for a reasonable term. The discussions resulted in the Compensation Package described above in the section entitled "CEO's Employment Agreement and Loan."

Compliance with Internal Revenue Code Section 162(m). Section 162(m) of the Internal Revenue Code, enacted in 1993, generally disallows a tax deduction to public companies for compensation over $1,000,000 paid to the corporation's Chief Executive Officer and the four other most highly compensated executive officers. Qualifying performance-based compensation will not be subject to the deduction limit if certain requirements are met. Other than pursuant to the Compensation Package, which is discussed within the section entitled "CEO's Employment Agreement and Loan," the Company has no current plan to pay any of its executive officers annual compensation over $1,000,000 and it currently intends to structure the performance-based portion of the compensation of its other executive officers in a manner that complies with this statute.

Compensation Committee Interlocks and Insider Participation

The current members of the Compensation Committee are Messrs. Alexander, Kever, and Noell. None of these individuals was at any time during fiscal 2000, or at any other time, an officer or employee of the Company. No executive officer of the Company serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of the Company's Board of Directors or Compensation Committee.

2. APPROVAL OF AMENDMENT TO THE 1999 STOCK OPTION PLAN

In January 2001, the Board of Directors adopted, subject to the approval of the stockholders of the Company, an amendment to the 1999 Stock Option Plan to increase the number of shares of Common Stock for which options may be granted under the 1999 Stock Option Plan from 2,000,000 to 3,000,000. At the Annual Meeting of Stockholders held on February 23, 1999, the stockholders approved the issuance of 1,000,000 shares of the Company's Common Stock under the 1999 Stock Option Plan. At the last Annual Meeting, held on February 22, 2000, the stockholders approved an additional 1,000,000 shares of the Company's Common Stock under the 1999 Stock Option Plan. Of the 2,000,000 shares so approved under the 1999 Stock Option Plan, only 24,045 shares remain available for new grants as of December 27, 2000. The addition of another 1,000,000 shares, bringing the total authorized under the 1999 Stock Option Plan to 3,000,000 shares, is the only proposed amendment to 1999 Stock Option Plan. None of the 1,000,000 shares that are the subject of this proposed amendment would be used for the contemplated exchange of options discussed above under "Contemplated Stock Option Exchange Offer." Under the terms of the Company's 1994, 1996, and 1999 Stock Option Plans, the number of shares underlying cancelled Existing Options would become available for issuance of options under the plans as if the cancelled Existing Options had never been granted and thus such shares would become available for issuance pursuant to the Replacement Options. Accordingly, if the proposed amendment is approved, all of the 1,000,000 shares will be available for additional new grants.

As of December 31, 2000, the Company has granted under the 1999 Stock Option Plan options to purchase an aggregate of 1,395,622 shares to all employees, including all current officers who are not executive officers, as a group. As of December 31, 2000, the Company has granted under the 1999 Stock Option Plan options to purchase an aggregate of 563,732 shares to all current executive officers of the Company as a group. As of December 31, 2000, the Company has granted under the 1999 Stock Option Plan options to purchase 117,410 shares, 69,023 shares, 36,000 shares, and 97,918 shares to Messrs. Russell, Mangold, Parkinson, and Vipond, respectively. As of December 31, 2000, the Company has granted under the 1999 Stock Option Plan options to purchase an aggregate of 143,000 shares to Mr. Fisher, all of which options granted to Mr. Fisher under the 1999 Stock Option Plan were cancelled prior to December 31, 2000. As of December 31, 2000, the Company has granted under the 1999 Stock Option Plan options to purchase an aggregate of 23,000 shares to Mr. Duman. No options have been granted under the 1999 Stock Option Plan to any other current directors who are not executive officers.

The last sale price of the Company's Common Stock on January 11, 2001, as reported by the NASDAQ National Market, was $12.875 per share.

The following summary description of the 1999 Stock Option Plan, as proposed to be amended, is qualified in its entirety by reference to the full text of the 1999 Stock Option Plan, which is set forth as Appendix B to this Proxy Statement.

The 1999 Stock Option Plan allows the Compensation Committee (or such other committee of the Board as may be directed by the Board) (the "Committee") to provide for awards for employees of the Company and its subsidiaries from time to time, in its sole discretion, of stock options (including incentive stock options qualifying under Section 422 of the Code and non-qualified stock options which do not so qualify), that the Committee determines to be consistent with the objectives and limitations of the 1999 Stock Option Plan. All employees of the Company or any subsidiary of the Company who are actively and customarily employed for 20 hours or more per week are eligible to participate in the 1999 Stock Option Plan, including employees who are members of the Board of Directors. As of December 31, 2000, the Company and its subsidiaries have approximately 1,896 eligible employees. The 1999 Stock Option Plan will expire, unless earlier terminated, on February 22, 2009.

If the proposed amendment to the 1999 Stock Option Plan is approved by the stockholders, an aggregate of 3,000,000 shares of Common Stock will be available under the 1999 Stock Option Plan, with 1,975,955 of these shares being subject to options previously granted under the 1999 Stock Option

Plan as of December 27, 2000. The shares subject to grants that terminate unexercised will be available for future grants. The total number of shares of Common Stock for which options may be granted to any "covered employee" within the meaning of Code Section 162(m) during any twelve-month period will not exceed 118,000 in the aggregate, subject to adjustment as provided below. Adjustments will be made in the number of shares subject to existing or future awards under the 1999 Stock Option Plan and in the exercise price of an outstanding award in the event that the outstanding shares of the Company's Common Stock are increased or decreased or changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation, without the receipt of consideration by the Company, by reason of a reorganization, merger or consolidation, recapitalization, reclassification, stock split, reverse stock split, split-up, combination or exchange of shares, or declaration of any dividends payable in Common Stock. In the event of (i) any offer or proposal to holders of the Company's Common Stock relating to the acquisition of their shares, including, without limitation, through purchase, merger or otherwise or (ii) any transaction generally relating to the acquisition of substantially all of the assets or business of the Company, or (iii) the dissolution or liquidation of the Company, the Committee may make such adjustment as it deems equitable in respect of outstanding options and the shares of Common Stock for which options may be granted, including without limitation the revision, cancellation or termination of any outstanding options or the change, conversion or exchange of the shares of the Company's Common Stock under outstanding options (and of the shares of the Company's Common Stock for which options may be granted under the 1999 Stock Option Plan) into or for securities or other property of another corporation. Additional limitations apply to the aggregate fair market value of shares granted under incentive stock options that are first exercisable during any calendar year in order to comply with Section 422 of the Code.

The exercise price of each option is determined by the Committee at the time the option is awarded. In the case of incentive stock options, the option exercise price may not be less than 100 percent of the fair market value of the Company's Common Stock on the date the option is granted. In the case of non-qualified stock options, the option exercise price may be equal to, more than or less than the fair market value of the Company's Common Stock on the date the option is granted.

Payment of the option exercise price may be made in cash, by certified check, or if authorized by the Committee, by delivery of shares of Common Stock having a fair market value on the date of delivery equal to the aggregate exercise price of the shares of Common Stock as to which the option is being exercised, or if authorized by the Committee, by authorizing the Company to withhold from the total number of shares of Common Stock to be acquired upon exercise of an option that number of shares of Common Stock having an aggregate fair market value (as of the date the withholding is effected) that would equal the aggregate exercise price of the shares of Common Stock as to which the option is being exercised, or by any combination of such methods of payment or by any other method of payment that may be authorized by the Committee.

Option grants under the 1999 Stock Option Plan are not transferable otherwise than by will or the laws of descent and distribution.

The 1999 Stock Option Plan is administered by the Committee. All members of the Committee are non-employee directors.

The Committee has authority to, within the limits of the 1999 Stock Option Plan, (i) determine the employees to whom options will be granted, (ii) designate an option as an incentive stock option or a non-qualified stock option, (iii) establish the number of shares of Common Stock that may be purchased under each option and the option exercise price, (iv) determine the time and the conditions subject to which options may be exercised in whole or in part, (v) fix the term of all options granted under the 1999 Stock Option Plan, provided that the term of any incentive stock option may not exceed ten years from the date of grant, (vi) determine how withholding taxes related to exercises are paid, (vii) establish any other terms, restrictions or conditions applicable to any option not inconsistent with the provisions of the

1999 Stock Option Plan, and (viii) take any other actions deemed necessary or advisable for the administration of the 1999 Stock Option Plan. The Committee will have the power to interpret the 1999 Stock Option Plan and may adopt, amend and rescind rules, not inconsistent with the provisions of the 1999 Stock Option Plan, as it deems advisable.

The Board of Directors may amend the 1999 Stock Option Plan from time to time as it deems desirable in its sole discretion without approval of the stockholders of the Company, except to the extent stockholder approval is required by Rule 16b-3 of the Exchange Act, applicable NASDAQ National Market or other stock exchange rules, applicable Code provisions, or other applicable laws or regulations. Amendments made without stockholder approval could increase the cost to the Company under the 1999 Stock Option Plan although the amount of such cost is not determinable. The Board of Directors may terminate the 1999 Stock Option Plan at any time in its sole discretion. Any termination or amendment of the 1999 Stock Option Plan may not alter or impair any rights or obligations under any option previously granted in any material adverse way without the affected participant's consent.

Within the limitations of the 1999 Stock Option Plan, the Committee may modify, extend or renew outstanding options or accept the cancellation of outstanding options for the granting of new options in substitution therefore, provided that, except for certain adjustments, (i) no modification of an option may, without the consent of the participant, alter or impair any rights or obligations under any option previously granted in any material adverse way without the affected participant's consent and (ii) the exercise price of outstanding options may not be altered, amended or modified.

Under current law, the United States federal income tax consequences to participants and the Company of options granted under the 1999 Stock Option Plan would generally be as set forth in the following summary. This summary does not purport to be a complete analysis of all potential United States federal income tax or other tax consequences relevant to employees and the Company or to describe tax consequences based upon particular circumstances. In addition, the summary does not discuss the income tax laws of any municipality, state or foreign country in which the participant may reside and to which the participant may be subject.

A participant receiving a non-qualified stock option under the 1999 Stock Option Plan does not recognize taxable income on the date of grant of the option. However, the participant must generally recognize ordinary income when a non-qualified stock option is exercised equal to the difference between the option exercise price and the fair market value, on the date of exercise, of the shares of the Company's Common Stock. If a holder of a non-qualified stock option pays the exercise price, in full or in part, with previously-acquired shares of the Company's Common Stock, special rules will apply. Special rules also apply if the shares acquired upon exercise of a non-qualified stock option are subject to vesting, or are subject to certain restrictions on resale under federal securities laws applicable to directors, executive officers or 10% shareholders. Any compensation includable in the gross income of the participant in respect of a non-qualified stock option will be subject to appropriate federal employment taxes.

A participant who is granted an incentive stock option will not recognize taxable income either on the date of grant or on the date of its timely exercise, although the spread on exercise of an incentive stock option would be an item of tax preference income potentially subject to the alternative minimum tax. Upon disposition of the shares of the Company's Common Stock acquired upon exercise of an incentive stock option, capital gain or loss would be recognized in an amount equal to the difference between the sales price and the option exercise price, provided the participant has not disposed of the shares of the Company's Common Stock within two years of the date of grant of the option nor within one year from the date of exercise. When a participant exercises an incentive stock option, the Company will not generally be entitled to a federal income tax deduction. However, if the participant disposes of stock acquired through exercise of such an option before meeting the required holding periods, the participant must generally recognize ordinary income in the amount of the difference between the option

exercise price and the fair market value, on the date of exercise, of the shares of the Company's Common Stock, except that if the disposition is a sale and the sale price is lower than the value of the shares on the exercise date, the lower sale price generally governs the amount of ordinary income. The Company would generally be entitled to a federal income tax deduction equal to the amount of ordinary income recognized by the participant. The balance of the gain, if any, will be capital gain taxed at the applicable capital gains rate. If the holder of an incentive stock option pays the exercise price, in full or in part, with previously-acquired shares of the Company's Common Stock, special rules will apply.

The Company will not be entitled to a federal income tax deduction upon the grant of an option under the 1999 Stock Option Plan. However, when a participant exercises a non-qualified stock option, the Company will generally be entitled to a federal income tax deduction in the amount of the difference between the option exercise price and the fair market value of the shares of the Company's Common Stock on the date of exercise. The payment by the participant to the Company of the exercise price has no tax consequences to the Company.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENT TO THE 1999 STOCK OPTION PLAN.

3. APPROVAL OF AMENDMENT TO THE 1999 EMPLOYEE STOCK PURCHASE PLAN

In December 2000, the Board of Directors adopted, subject to approval of the stockholders of the Company, an amendment to the Company's 1999 Employee Stock Purchase Plan to increase the number of shares of Common Stock that may be purchased by participating employees of the Company from 250,000 to 750,000. At the Annual Meeting of Stockholders held on February 23, 1999, the Company's Stockholders approved the 1999 Employee Stock Purchase Plan (the "ESPP"). Of the initial 250,000 shares of Common Stock authorized under the ESPP 77,606 authorized shares remain available for sale as of December 31, 2000. After the next scheduled quarterly purchase of shares under the ESPP on January 31, 2001, at which time it is anticipated that approximately 40,000 shares will be sold to the Company's employees, there will be an insufficient number of authorized shares available with which to continue the ESPP. As of December 31, 2000, the ESPP had 743 active participants. The increase in the number of shares of Common Stock that may be purchased under the ESPP by participating employees from 250,000 to 750,000 is the only proposed amendment to the ESPP.

As of December 31, 2000, the Company has sold under the ESPP an aggregate of 169,734 shares to employees, including all current officers who are not executive officers, as a group. As of December 31, 2000, the Company sold an aggregate of 2,660 shares to all current executive officers of the Company as a group. As of December 31, 2000, the Company sold 1,621 shares to Mr. Russell. As of December 31, 2000, there are approximately 1,700 employees eligible to participate in the ESPP.

The last sale price of the Company's Common Stock on January 11, 2001, as reported by the NASDAQ National Market, was $12.875 per share.

The following summary description of the ESPP, as proposed to be amended, is qualified in its entirety by reference to the full text of the 1999 ESPP, which is set forth as Appendix C to this Proxy Statement.

The ESPP became effective April 1, 1999. The ESPP terminates on April 30, 2004, unless terminated sooner by the Company's Board of Directors.

The ESPP permits eligible employees of the Company and participating subsidiaries to purchase the Company's Common Stock through payroll deductions during twenty (20) consecutive participation periods, beginning with the participation period commencing April 1, 1999. The participation periods are three months in length with the exception of the first participation period, which was four months in length, having commenced on April 1, 1999 and having ended on July 31, 1999. In general, eligible

employees can elect for each participation period to purchase full shares through payroll deductions of up to 10 percent of base pay, but in no event may the participant's rights to purchase shares of Common Stock accrue at a rate that exceeds $25,000 of fair market value of Common Stock in a calendar year. The purchase price a participant pays for the shares is equal to 85% of the closing market bid price of the Common Stock on the first business day or the last business day of each participation period, whichever is lower. Shares for the ESPP may be authorized and unissued shares or treasury shares.

Eligibility to participate will generally be extended to all regular employees of the Company and its participating subsidiaries who are actively and customarily employed for 20 hours or more per week and who have completed three months of employment. Officers and members of the Board of Directors who are eligible employees are also permitted to participate. An employee is ineligible to participate if immediately after such grant, such employee would own stock possessing 5 percent or more of the total combined voting power or value of all classes of stock of the Company or any subsidiary of the Company, such ownership to be determined by applying the rules of 424(d) of the Code and treating stock which the employee may purchase under outstanding options as stock owned by the employee.

The ESPP will be administered by the Compensation Committee of the Board of Directors or such other committee as established by the Board of Directors (the "Committee"). The Committee may amend the ESPP or adopt sub-plans, in its sole discretion, in order to conform the terms of the ESPP to the requirements of local law with respect to participating subsidiaries that employ participants who reside outside the United States. The Committee will have the power to interpret the ESPP and may adopt, amend and rescind rules, not inconsistent with the provisions of the ESPP, that it deems advisable. The ESPP may be amended by the Board of Directors from time to time as it deems desirable in its sole discretion and without approval of the stockholders of the Company, except to the extent stockholder approval is required by Rule 16b-3 of the Exchange Act, applicable NASDAQ National Market or other stock exchange rules, applicable provisions of the Code, or other applicable laws or regulations. The Board of Directors may terminate the ESPP at any time in its sole discretion.

The proceeds of the sale of stock received under the ESPP will constitute general funds of the Company and may be used by it for any purpose.

The number of shares issued under the ESPP will be adjusted by the Board of Directors in the event that the outstanding shares of the Company's Common Stock are increased or decreased or changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation without the receipt of consideration by the Company, by reason of reorganization, merger or consolidation, recapitalization, reclassification, stock split, reverse stock split, split-up, combination or exchange of shares, or declaration of any dividends payable in Common Stock. In the event of (i) any offer or proposal to holders of the Company's Common Stock relating the acquisition of their shares, including, without limitation, through purchase, merger or otherwise or (ii) any transaction generally relating to the acquisition of substantially all of the assets of the Company, or (iii) the dissolution or liquidation of the Company, the Board of Directors may make such adjustments as it deems equitable.

Under current law, the United States federal income tax consequences to participants and the Company of options granted under the ESPP would generally be as set forth in the following summary. This summary does not purport to be a complete analysis of all potential United States federal income tax or other tax consequences relevant to employees and the Company or to describe tax consequences based upon particular circumstances. In addition, the summary does not discuss the income tax laws of any municipality, state or foreign country in which the participant may reside and to which the participant may be subject.

If shares of Common Stock are issued to a participant under the ESPP, and if no disposition of such shares is made within two years of the first day of the participation period, or within one year after the transfer to such participant of such shares, or in the event of the participant's death (whenever occurring)

while owning such shares, then; (a) no income will be realized by the participant at the time of the transfer of the shares to such participant and (b) when the participant sells or otherwise disposes of such shares (or dies holding the shares), there will be included in his or her gross income, as compensation, an amount equal to the lesser of (i) the amount by which the fair market value of the shares on the first day of the participation period exceeds the purchase price for the shares, or (ii) the amount by which the fair market value at the time of disposition or death exceeds the purchase price for the shares. Any further gain will be treated for federal income tax purposes as long-term capital gain, provided that the employee holds the shares for the applicable long-term capital gain holding period after the last day of the participation period applicable to such shares.

No deduction will be allowed to the Company for federal income tax purposes in connection with the grant or exercise of any right to purchase shares under the ESPP if there is no disposition of the shares within either the two-year of one-year periods referred to above. If there is a disposition of shares by a participant within either of these periods, such participant will realize ordinary income in the year of disposition in an amount equal to the difference between the purchase price and the fair market value of the shares at the time of purchase, and the Company will generally be entitled to a deduction in the same amount. The amount of ordinary income realized by the participant may be subject to withholding for taxes. Any difference between the amount received by an employee upon such a disposition and the fair market value of the shares at the time of purchase will be capital gain or loss, as the case may be.

If the purchase of shares under the ESPP is not pursuant to an "employee stock purchase plan" under Section 423 of the Code, the purchase will be treated as the exercise of a non-qualified stock option. The participant will therefore recognize ordinary income at the time of purchase in an amount equal to the excess of the fair market value of the shares acquired over the purchase price, and the Company will generally be entitled to a deduction in the same amount. Such income is subject to withholding of income and employment taxes. Any gain or loss recognized on a subsequent sale of the shares, as measured by the difference between the sale proceeds and the sum of (a) the purchase price for such shares and (b) the amount of ordinary income recognized on the purchase of such shares, will be treated as capital gain or loss, as the case may be.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENT TO THE 1999 EMPLOYEE STOCK PURCHASE PLAN.

4. RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

The Board of Directors has appointed the firm of Arthur Andersen LLP, independent public accountants, as the auditors of the Company for the fiscal year ending September 30, 2001, subject to the ratification of such appointment by stockholders at the Annual Meeting. Arthur Andersen LLP has audited the Company's financial statements since the Company's inception in 1993.

If the foregoing appointment of Arthur Andersen LLP is not ratified by the stockholders, the Board of Directors will appoint other independent accountants whose appointment for any period subsequent to the 2001 Annual Meeting of Stockholders will be subject to approval of stockholders at that meeting. Representatives of Arthur Andersen LLP are expected to be present at the Company's Annual Meeting and will have the opportunity to make statements and/or respond to appropriate questions from stockholders present at the meeting.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR RATIFICATION OF ARTHUR ANDERSEN LLP AS THE COMPANY'S INDEPENDENT AUDITORS.

5. OTHER MATTERS

The Board of Directors does not know of any matters that are to be presented at the Annual Meeting other than those stated in the Notice of Annual Meeting and referred to in this Proxy Statement. If any other matters should properly come before the Meeting, it is intended that the proxies in the accompanying form will be voted as the persons named therein may determine in their discretion.

Stockholders Proposals

Proposals of stockholders intended to be presented at the Company's next Annual Meeting of Stockholders must be received at the Corporate Secretary's office, 224 South 108th Avenue, Omaha, Nebraska 68154, no later than September 21, 2001, to be considered for inclusion in the proxy statement and form of proxy for that meeting.

Pursuant to Rule 14a-4(c) under the Securities Exchange Act of 1934, if the Company does not receive advance notice of a stockholder proposal to be raised at its next Annual Meeting in accordance with the requirements of the Company's By-laws, management may use its discretionary voting authority to vote management proxies on the stockholder proposal without any discussion of the matter in the proxy statement. The Company's By-laws provide that written notice of a stockholder proposal must be delivered to or mailed and received by the Secretary of the Company at the principal executive offices of the Company not less than 80 days prior to the meeting; provided, however, that in the event that the date of the meeting is not publicly announced by the Company by mail, press release or otherwise more than 90 days prior to the meeting, notice by the stockholder to be timely must be delivered to the Secretary of the Company not later than the close of business on the tenth day following the day on which such announcement of the date of the meeting was communicated to stockholders. The stockholder's notice must set forth as to each matter the stockholder proposes to bring before the Annual Meeting (a) a brief description of the business desired to be brought before the Annual Meeting and the reasons for conducting such business at the Annual Meeting, (b) the name and address, as they appear on the Company's books, of the stockholder proposing such business, (c) the class and number of shares of the Company which are beneficially owned by the stockholder, and (d) any material interest of the stockholder in such business. The Company's By-laws also provide that the chairman of an Annual Meeting shall, if the facts warrant, determine and declare to the Meeting that business was not properly brought before the Meeting, and if he should so determine, that any such business not properly brought before the Meeting shall not be transacted.

The preceding two paragraphs on stockholder proposals apply to both holders of Common Stock and to holders of Exchangeable Shares, provided that any proposals of holders of Exchangeable Shares should be addressed to the Trustee (at Wells Fargo Bank Minnesota, National Association, 6th and Marquette N9303-120, Minneapolis, MN 55479) rather than to the Company's Secretary.

By Order of the Board of Directors,

David P. Stokes
Secretary

part; (v) determining the form of the consideration that may be used to purchase shares of Common Stock upon exercise of any Option (including the circumstances under which the Company's issued and outstanding shares of Common Stock or the shares of Common Stock available under the Option may be used by a Participant to exercise an Option) and establishing procedures in connection therewith; (vi) imposing restrictions and/or conditions with respect to shares of Common Stock acquired upon exercise of an Option; (vii) determining the circumstances under which shares of Common Stock acquired upon exercise of any Option may be subject to repurchase by the Company, including without limitation, the circumstances and conditions subject to which a proposed sale of shares of Common Stock acquired upon exercise of an Option may be subject to the Company's right of first refusal (as well as the terms and conditions of any such right of first refusal); (viii) establishing procedures whereby a number of shares of Common Stock may be withheld from the total number of shares of Common Stock to be issued upon exercise of an Option to meet the obligation of withholding for federal and state income and other taxes, if any, incurred by the Participant upon exercise of an Option; (ix) accelerating or, with the consent of the Participant, deferring the time when outstanding Options may be exercised, provided, however, that any ISO's shall be "accelerated" within the meaning of Section 424(h) of the Code; (x) establishing any other terms, restrictions and/or conditions applicable to any Option not inconsistent with the provisions of the Plan; (xi) authorizing any person to execute on behalf of the Company any instrument required to effectuate the grant of an Option previously granted by the Committee; and (xii) taking any other actions deemed necessary or advisable for the administration of the Plan.

5.3. The Committee shall be authorized to interpret the Plan and may, from time to time, adopt, amend and rescind such rules, regulations and procedures, not inconsistent with the provisions of the Plan, as it may deem advisable to carry out the purpose of the Plan.

5.4. The interpretation and construction by the Committee of any provision of the Plan, any Option granted hereunder or any agreement evidencing any such Option shall be final, conclusive and binding upon all parties.

5.5 Only members of the Committee shall vote on any matter affecting the administration of the Plan or the granting of Options under the Plan.

5.6. All expenses and liabilities incurred by the Committee in the administration of the Plan shall be borne by the Company. The Committee may employ attorneys, consultants, accountants or other persons in connection with the administration of the Plan. The Company, and its officers and directors, shall be entitled to rely upon the advice, opinions or valuations of any such persons. No member of the Board of Directors or the Committee shall be liable for any action, determination or interpretation taken or made in good faith with respect to the Plan or any Option granted hereunder.

Section 6. Terms and Conditions of Options.

6.1. ISO's. Except as otherwise provided in this Section 6.1, the terms and conditions of each ISO granted under the Plan shall be specified by the Committee, in its sole discretion, and shall be set forth in a written ISO agreement between the Company and the Participant in such form as the Committee shall approve. No person shall have any rights under any ISO granted under the Plan unless and until the Company and the person to whom such ISO shall have been granted shall have executed and delivered an agreement expressly granting the ISO to such person and containing provisions setting forth the terms for the ISO. The terms and conditions of each ISO shall be such that each ISO issued hereunder shall constitute and shall be treated as an "incentive stock option" as defined in Section 422 of the Code. The terms and conditions of any ISO granted hereunder need not be identical

B-3

to those of any other ISO granted hereunder. The terms and conditions of each ISO agreement shall include the following:

(a) The ISO exercise price shall be fixed by the Committee but shall in no event be less than 100% (or 110% in the case of an Employee referred to in Section 4.3(b) hereof) of the Fair Market Value of the shares of Common Stock subject to the ISO on the date the ISO is granted.

(b) ISO's shall not be transferable otherwise than by will or the laws of descent and distribution, and, during a Participant's lifetime, an ISO shall be exercisable only by the Participant.

(c) The Committee shall fix the term of all ISO's granted pursuant to the Plan (including the date on which such ISO shall expire and terminate) provided, however, that such term shall in no event exceed ten years from the date on which such ISO is granted (or, in the case of an ISO granted to an Employee referred to in Section 4.3(b) hereof, such term shall in no event exceed five years from the date on which such ISO is granted). Each ISO shall be exercisable in such amount or amounts, under such conditions and at such times or intervals or in such installments as shall be determined by the Committee in its sole discretion.

6.3 Vesting; Period for Exercise of Option. In the sole discretion of the Committee, the terms and conditions of any Option may include any of the following provisions:

(a) An Option may not be exercised during the first year from the date it is granted. After the first anniversary of the date on which an Option is granted, it may be exercised as to not more than 33¹/3% of the shares of Common Stock available for purchase under the Option and, after the second and third anniversaries of the Option grant date, it may be exercised as to not more than an additional 33¹/3% of such shares plus any shares as to which the Option might theretofore have been exercisable but shall not have been exercised.

(b) Subject to subsection (d) below, if a Participant ceases to be an Employee of the Company or a Subsidiary of the Company for any reason other than as a result of his death or Disability, the unexercised portion of any Option held by such Participant at that time may only be exercised within one month after the date on which the Participant ceased to be so employed, but no later than the date the Option expires, and only to the extent that the Participant could have otherwise exercised such Option as of the date on which he ceased to be so employed. To the extent that the Participant is not entitled to exercise the Option on such date, or if the Participant does not exercise it within the time specified, such Option shall terminate. The Committee shall have the authority to determine the date a Participant ceases to be an Employee.

(c) Subject to subsection (d) below, if a Participant ceases to be an Employee of the Company or a Subsidiary of the Company by reason of his Disability, the unexercised portion of any Option held by such Participant at that time may only be exercised within one year after the date on which the Participant ceased to be so employed, but no later than the date the Option expires, and to the extent that the Participant could have otherwise exercised such Option if it had been completely exercisable. To the extent that the Participant is not entitled to exercise the Option on such date, or if the Participant does not

B-5

exercise it within the time specified, such Option shall terminate. The Committee shall have the authority to determine the date a Participant ceases to be an Employee by reason of his Disability.

Such Option may be exercised by the executor or administrator of the Participant's estate or by any person or persons who shall have acquired the Option directly from the Participant by bequest or inheritance. To the extent that the Option is not entitled to be exercised on such date or if the Option is not exercised within the time specified, such Option shall terminate.

6.4. Procedures for Exercise of Option; Rights of Stockholder. Any Option granted hereunder shall be exercisable at such times, under such conditions, as shall be determined by the Committee and in accordance with the terms of the Plan. An Option may not be exercised for a fraction of a share of Common Stock. An Option shall be deemed to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option agreement by the Participant entitled to exercise the Option and full payment for the shares of Common Stock with respect to which the Option is exercised has been received by the Company. Full payment may, as authorized by the Committee, consist of any form of consideration and method of payment allowable hereunder. Payment for the shares of Common Stock upon exercise of an Option shall be made in cash, by certified check, or if authorized by the Committee, by delivery of other shares of Common Stock having a Fair Market Value on the date of delivery equal to the aggregate exercise price of the shares of Common Stock as to which the Option is being exercised, or if authorized by the Committee, by authorizing the Company to withhold from the total number of shares of Common Stock to be acquired upon exercise of an Option that number of shares of Common Stock having an aggregate Fair Market Value (as of the date the withholding is effected) that would equal the aggregate exercise price of the shares of Common Stock as to which the Option is being exercised, or by any combination of such methods of payment or by any other method of payment that may be permitted under applicable law and the Plan and authorized by the Committee under Section 5.2 of the Plan. Upon the receipt of notice of exercise and full payment for the shares of Common Stock, the shares of Common Stock shall be deemed to have been issued and the Participant shall be entitled to receive such shares of Common Stock and shall be a stockholder with respect to such shares, and the shares of Common Stock shall be considered fully paid and nonassessable. No adjustment will be made for a dividend or other right for which the record date is prior to the date on which the stock certificate is issued, except as provided in Section 7 of the Plan. Each exercise of an Option shall reduce, by an equal number, the total number of shares of Common Stock that may thereafter be purchased under such Option.

Section 7. Adjustments.

7.1 In the event that the outstanding shares of the Company's Common Stock shall be increased or decreased or changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation, effected without the receipt of consideration by the Company, through reorganization, merger or consolidation, recapitalization, reclassification, stock split, reverse stock split, split-up, combination or exchange of shares or declaration of any dividends payable in Common Stock, the Board of Directors shall appropriately adjust, subject to any required action by the stockholders of the Company, (i) the number of shares of Common Stock (and the Option exercise price per share) subject to the unexercised portion of any outstanding Option (to the nearest possible full share), provided, however, that the limitations of Section 424 of the Code shall apply with respect to adjustments made to ISO's and (ii) the number of shares of Common Stock for which Options may be granted under the Plan, as set forth in Section 4.1 hereof, and such adjustments shall be final, conclusive

B-6

and binding for all purposes of the Plan. Except as expressly provided herein, no issuance by the Company of shares of stock of any class shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option.

7.2 Notwithstanding the foregoing, in the event of (i) any offer or proposal to holders of the Company's Common Stock relating to the acquisition of their shares, including, without limitation, through purchase, merger or otherwise, or (ii) any transaction generally relating to the acquisition of substantially all of the assets or business of the Company, or (iii) the dissolution or liquidation of the Company, the Committee may make such adjustment as it deems equitable in respect of outstanding Options (and in respect of the shares of Common Stock for which Options may be granted under the Plan), including, without limitation, the revision, cancellation, or termination of any outstanding Options, or the change, conversion or exchange of the shares of the Company's Common Stock under outstanding Options (and of the shares of the Company's Common Stock for which Options may be granted under the Plan) into or for securities or other property of another corporation. Any such adjustments by the Committee shall be final, conclusive and binding for all purposes of the Plan.

Section 8. Effect of the Plan on Employment Relationship. Neither this Plan nor any Option granted hereunder to a Participant shall be construed as conferring upon such Participant any right to continue in the employ of the Company or any Subsidiary of the Company as the case may be, or limit in any respect the right of the Company or any Subsidiary of the Company to terminate such Participant's employment with the Company or any Subsidiary of the Company, as the case may be, at any time.

Section 9. Amendment of the Plan. The Board of Directors may amend the Plan from time to time as it deems desirable in its sole discretion without approval of the stockholders of the Company, except to the extent stockholder approval is required by Rule 16b-3 of the Exchange Act, applicable NASDAQ National Market or stock exchange rules, applicable Code provisions, or other applicable laws or regulations.

Section 10. Termination of the Plan. The Board of Directors may terminate the Plan at any time in its sole discretion. No Option may be granted hereunder after termination of the Plan. The termination or amendment of the Plan shall not alter or impair any rights or obligations under any Option previously granted under the Plan in any material adverse way without the affected Participant's consent.

Section 11. Modification, Extension and Renewal of Options. Within the limitations of the Plan and subject to Section 7, the Committee may modify, extend or renew outstanding Options or accept the cancellation of outstanding Options for the granting of new Options in substitution therefore. Notwithstanding the preceding sentence, except for any adjustment described in Section 7, (i) no modification of an Option shall, without the consent of the Participant, alter or impair any rights or obligations under any Option previously granted under the Plan in any material adverse way without the affected Participant's consent, and (ii) the exercise price of outstanding Options may not be altered, amended or modified.

Section 12. Governing Law. The Plan and any and all Option agreements executed in connection with the Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflict of laws principles.

Section 13. No Strict Construction. No rule of strict construction shall be applied against the Company, the Committee, or any other person in the interpretation of any of the terms of the Plan, any Option agreement, any Option granted under the Plan, or any rule, regulation or procedure established by the Committee.

Section 14. Successors. This Plan is binding on and will inure to the benefit of any successor to the Company, whether by way of merger, consolidation, purchase, or otherwise.

B-7

Section 15. Severability. If any provision of the Plan or an Option agreement shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan or such agreement, and the Plan and such agreement shall each be construed and enforced as if the invalid provisions had never been set forth therein.

Section 16. Plan Provisions Control. The terms of the Plan govern all Options granted under the Plan, and in no event will the Committee have the power to grant any Option under the Plan, which is contrary to any of the provisions of the Plan. In the event any provision of any Option granted under the Plan shall conflict with any term in the Plan as constituted on the grant date of such Option, the term in the Plan as constituted on the grant date of such Option shall control.

Section 17. Headings. The headings used in the Plan are for convenience only, do not constitute a part of the Plan, and shall not be deemed to limit, characterize, or affect in any way any provisions of the Plan, and all provisions of the Plan shall be construed as if no captions had been used in the Plan.

Section 18. Effective Date of the Plan. The Plan shall be submitted to the stockholders of the Company for approval and ratification at the next regular or special meeting thereof to be held after January 1, 1999. Unless at such meeting the Plan is approved and ratified by the stockholders of the Company, in the manner provided by the Company's By-Laws, then and in such event, the Plan and any then outstanding Options that may have been conditionally granted prior to such stockholder meeting shall become null and void and of no further force and effect. Subject to the immediately preceding sentence, the Plan shall be effective as of February 23, 1999. The Plan shall continue in effect for a term of 10 years unless sooner terminated under Section 10.

Without limiting the generality of the foregoing, the Committee is specifically authorized to adopt rules and procedures regarding handling of payroll deductions, payment of interest, conversion of local currency, payroll tax and withholding procedures which vary with local requirements. With respect to any Participating Subsidiary which employs Participants who reside outside of the United States, and notwithstanding anything herein to the contrary, the Committee may in its sole discretion amend or vary the terms of the Plan in order to conform such terms with the requirements of local law or to meet the objectives and purpose of the Plan, and the Committee may, where appropriate, establish one or more sub-plans to reflect such amended or varied provisions which sub-plans may be designed to be outside the scope of Code Section 423. The provisions of such sub-plans may take precedence over other provisions of the Plan, with the exception of Section 4.01, but unless otherwise superseded by the terms of such sub-plan, the provisions of the Plan shall govern the operation of such sub-plan.

7.06 Tax Withholding.

Section 10. Adjustments.

10.01 Changes In Capitalization. In the event that the outstanding shares of the Company's Common Stock shall be increased or decreased or changed into or exchanged for a different number or kind of shares of stock or other securities of the Company or of another corporation, effected without the receipt of consideration by the Company, through reorganization, merger or consolidation, recapitalization, reclassification, stock split, reverse stock split, split-up, combination or exchange of shares or declaration of any dividends payable in Common Stock, the Board of Directors shall appropriately adjust, subject to any required action by the stockholders of the Company, (i) the number of shares of Common Stock (and the Option price per share) subject to the unexercised portion of any outstanding Option (to the nearest possible full share), provided, however, that the limitations of Section 424 of the Code shall apply with respect to such adjustments and (ii) the number of shares of Common Stock for which Options may be granted under the Plan, as set forth in Section 4.01 hereof, and such adjustments shall be final, conclusive and binding for all purposes of the Plan. Except as expressly provided herein, no issuance by the Company of shares of stock of any class shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an Option.

10.02 Acquisition, Merger, Sale of Assets, Dissolution or Liquidation. Notwithstanding the foregoing, in the event of (i) any offer or proposal to holders of the Company's Common Stock relating to the acquisition of their shares, including, without limitation, through purchase, merger or otherwise, or (ii) any transaction generally relating to the acquisition of substantially all of the assets or business of the Company, or (iii) the dissolution or liquidation of the Company, the Board of Directors may make such adjustment as it deems equitable in respect of outstanding Options (and in respect of the shares of Common Stock for which Options may be granted under the Plan), including, without limitation, the revision, cancellation, or termination of any outstanding Options, or the change, conversion or exchange of the shares of the Company's Common Stock under outstanding Options (and of the shares of the Company's Common Stock for which Options may be granted under the Plan) into or for securities or other property of another corporation. Any such adjustments by the Board of Directors shall be final, conclusive and binding for all purposes of the Plan.

Section 11. Effect of the Plan on Employment Relationship. Neither this Plan nor any Option granted hereunder to a Participant shall be construed as conferring upon such Participant any right to continue in the employ of the Company or any Subsidiary of the Company as the case may be, or limit in any respect the right of the Company or any Subsidiary of the Company to terminate such Participant's employment with the Company or any Subsidiary of the Company, as the case may be, at any time.

Section 12. Amendment of the Plan. The Board of Directors may amend the Plan from time to time as it deems desirable in its sole discretion without approval of the stockholders of the Company, except to the extent stockholder approval is required by Rule 16b-3 of the Securities Exchange Act of 1934, as amended, applicable NASDAQ National Market or stock exchange rules, applicable provisions of the Code, or other applicable laws or regulations.

Section 13. Termination of the Plan. The Board of Directors may terminate the Plan at any time in its sole discretion. No Option may be granted hereunder after termination of the Plan. The termination or amendment of the Plan shall not alter or impair any rights or obligations under any Option theretofore granted under the Plan in any material adverse way without the consent of the affected Participant.

Section 14. Governing Law. The Plan and any and all Option agreements executed in connection with the Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to conflict of laws principles.

Section 15. No Strict Construction. No rule of strict construction shall be applied against the Company, the Committee, or any other person in the interpretation of any of the terms of the Plan, any

C-6

Option agreement, any Option granted under the Plan, or any rule, regulation or procedure established by the Committee.

Section 16. Successors. This Plan is binding on and will inure to the benefit of any successor to the Company, whether by way of merger, consolidation, purchase, or otherwise.

Section 17. Severability. If any provision of the Plan or an Option agreement shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan or such agreement, and the Plan and such agreement shall each be construed and enforced as if the invalid provisions had never been set forth therein.

Section 18. Plan Provisions Control. Except as otherwise provided in Section 5.06, the terms of the Plan govern all Options granted under the Plan, and in no event will any Option be granted under the Plan which is contrary to any of the provisions of the Plan. In the event any provision of any Option granted under the Plan shall conflict with any term in the Plan as constituted on the grant date of such Option, the term in the Plan as constituted on the grant date of such Option shall control except as otherwise provided in Section 5.06.

Section 19. Headings. The headings used in the Plan are for convenience only, do not constitute a part of the Plan, and shall not be deemed to limit, characterize, or affect in any way any provisions of the Plan, and all provisions of the Plan shall be construed as if no captions had been used in the Plan.

Section 20. Effective Date of the Plan. The Plan shall be submitted to the stockholders of the Company for approval and ratification at the next regular or special meeting thereof to be held after January 1, 1999. Unless at such meeting the Plan is approved and ratified by the stockholders of the Company, in the manner provided by the Company's By-Laws, then and in such event, the Plan shall become null and void and of no further force and effect. Subject to the immediately preceding sentence, the Plan shall be effective as of April 1, 1999. The Plan shall continue in effect until April 30, 2004 unless sooner terminated under Section 13.
