Proxy Solicitation

        The shares of the Company's Class A Common Stock, $.005 par value per share ("Common Stock"), represented by the proxies received pursuant to this solicitation and not timely 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 either 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 attends the Annual Meeting may revoke a previously submitted proxy by voting in person. Subject to any such revocation, all Common Stock represented by properly executed proxies will be voted in accordance with the specifications on the proxy. If no such specifications are made, proxies will be voted FOR Proposal 1, the election of the five nominees for Director listed in this Proxy Statement 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. Proposal 1 may be referred to in this Proxy Statement as the "Proposal."

        Common Stockholders whose shares of Common Stock are registered directly with the Company's transfer agent, Wells Fargo Bank Minnesota, National Association, may vote via the Internet or telephone. Such Common Stockholders should refer to the enclosed proxy card 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. CST (Omaha time) on February 26, 2003, and the telephone voting facilities for Common Stockholders of record will close at 11:00 a.m. CST (Omaha time) on February 26, 2003. 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.

        The Company will bear the expense of preparing, printing and mailing this Proxy Statement and the 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 Common Stockholders of record at the close of business on January 15, 2003 (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 35,445,129 shares of Common Stock issued and outstanding, excluding 1,476,145 shares of Common Stock held as treasury stock by the Company. The shares of Common Stock held as treasury stock are not entitled to be voted. Each Common Stockholder is entitled to one vote per share of Common Stock held for the election of Directors and on all other matters to be voted on by the Company's stockholders. Common Stockholders may not cumulate their votes in the election of Directors. Unless the context requires otherwise, all references to "shares" in this Proxy Statement include all shares of Common Stock entitled to vote at the Annual Meeting.

        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. Abstentions and "broker non-votes" are counted for the purpose of determining the presence of a quorum. "Broker non-votes" are shares represented at the Annual Meeting and held by brokers or nominees as to which (1) instructions to vote have not been received from the beneficial owners and (2) the broker nominee does not have discretionary voting power on a particular matter.

        Election of a Director requires the affirmative vote 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. The five persons receiving the greatest number of votes at the Annual Meeting shall be elected as Directors. Since only affirmative votes count for this purpose, abstentions and broker non-votes will not affect the outcome.

AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR
AND FISCAL YEAR-END OPTION VALUES

(1)

"In-the-Money" stock options are those stock options outstanding at the end of the last fiscal year for which the fair market value (closing bid price per the NASDAQ National Market) of the Common Stock at the end of the last fiscal year ($6.15 per share on September 30, 2002) exceeded the exercise price of the stock options. This table includes stock options that were granted pursuant to the terms of the Company's Stock Option Exchange Offer.

Stock Option Exchange Offer

        On August 1, 2001, the Company announced a voluntary stock option exchange program (the "Exchange Program") offering to exchange all outstanding options to purchase shares of the Company's Common Stock granted under the 1994 Stock Option Plan, 1996 Stock Option Plan and 1999 Stock Option Plan held by eligible employees or eligible non-employee Directors for new options under the same option plans. The Exchange Program required any person tendering an option grant for exchange to also tender all subsequent option grants with a lower exercise price received by that person during the six months immediately prior to the date the options accepted for exchange were cancelled. Options to acquire a total of 3,089,100 shares of the Company's Common Stock with exercise prices ranging from $2.50 to $45.00 were eligible to be exchanged under the Exchange Program. The offer expired on August 28, 2001, and the Company cancelled 1,946,550 shares tendered by 578 optionholders. As a result of the Exchange Program the Company granted replacement stock options to acquire 1,823,000 shares of the Company's Common Stock at an exercise price of $10.04. The difference between the number of shares cancelled and the number of shares granted relates to options cancelled by employees who terminated their employment with the Company between the cancellation date and regrant date. The exercise price of the replacement options was the fair market value of the Company's Common Stock on the grant date of the new options, which was March 4, 2002 (a date at least six months and one day after the date of cancellation). The new shares have a vesting schedule of 1/18 per month beginning on the grant date of the new options, except for options tendered by executive officers under the 1994 Stock Option Plan, which vest 25% annually on each anniversary of the grant date of the new options. The Exchange Program was designed to comply with Financial Accounting Standards Board ("FASB") Interpretation No. 44, "Accounting for Certain Transactions Involving Stock Compensation," for fixed plan accounting.

        To following table reflects the participation of each Named Executive Officer in the Exchange Program:

TEN-YEAR OPTION REPRICINGS

Current CEO's Employment Agreement

        On December 3, 2001, the Company entered into an Employment Agreement with Mr. Derkacht, a nominee to the Board of Directors. The Employment Agreement provides for the appointment of Mr. Derkacht as President and Chief Executive Officer of the Company for a three-year term commencing January 2, 2002. The term will be automatically extended for successive one-year terms, unless either the Company or Mr. Derkacht gives notice at least 90 days prior to the expiration of the term of an intention to terminate the Employment Agreement. Under the Employment Agreement, Mr. Derkacht will be paid a base salary of $300,000 per annum and entitled to participate in a management incentive compensation program that could provide additional targeted compensation of $37,500 each quarter the Company achieves certain financial results. The quarterly management incentive compensation payouts will vary within a range of 0% to 150% of the targeted compensation based on the actual financial performance of the Company. The base salary and management incentive compensation may be increased during the term but may not be decreased unless, under certain circumstances, there is a pro rata across-the-board decrease for all executive level management employees of the Company. Mr. Derkacht's employment may be terminated for cause, deemed for the purposes of the Employment Agreement to exist if the Board, in good faith, determines that Mr. Derkacht has engaged in gross and flagrant non-performance, misconduct or negligence of his duties or gross and flagrant dishonesty relating to the business of the Company. If Mr. Derkacht's employment is terminated without cause, he will be entitled to a lump-sum payment of $150,000. If the Company experiences a "change in control" while Mr. Derkacht is employed and his employment is terminated within two years after the "change in control," Mr. Derkacht will be entitled, with certain exceptions, to receive a lump-sum payment equal to 100% of his annual base salary.

        Pursuant to the Employment Agreement, on January 2, 2002, Mr. Derkacht was granted a stock option under the Company's 1999 Stock Option Plan to purchase 100,000 shares of Common Stock at an exercise price of $11.86 per share, the market price of the Common Stock on the date of grant. On February 19, 2002, Mr. Derkacht was granted options to purchase an aggregate of 400,000 shares of Common Stock at an exercise price of $9.80 per share, the market price of the shares on the date of grant. All stock options granted to Mr. Derkacht will vest 33¹/3% per year at the end of each of three years commencing on the date of grant; provided, however, that with respect to 200,000 shares of Common Stock, vesting is subject to acceleration upon the Company meeting certain performance targets and/or the occurrence of certain events.

Interim CEO's Employment Agreements

        Effective May 1, 2001, the Company entered into an employment agreement with Mr. Fendley pursuant to which Mr. Fendley agreed to serve as Interim Chief Executive Officer. The agreement required the Company to pay Mr. Fendley a base salary of $30,000 per month, reimburse Mr. Fendley for all reasonable and documented business expenses and permitted Mr. Fendley and his dependents to participate in the Company's benefit plans. Mr. Fendley agreed to certain non-competition and non-solicitation provisions pursuant to the agreement. Effective October 2, 2001, the Company and Mr. Fendley entered into a second employment agreement upon substantially the same terms and conditions as were provided in the earlier agreement. However, Mr. Fendley and the Company agreed that Mr. Fendley would serve for two consecutive terms of three months pursuant to the second agreement. During the initial term, Mr. Fendley agreed to devote all of his business time to the Company; and during the subsequent term, Mr. Fendley agreed to work the number of hours as may be requested by the Chairman of the Board. Additionally, Mr. Fendley was eligible under the second agreement to receive targeted management incentive compensation of $45,000 per quarter with respect to the fiscal quarters ending December 31, 2001 and March 31, 2002; additionally, Mr. Fendley received a $45,000 cash bonus with respect to the fiscal year ended September 30, 2001. Pursuant to and for the remaining term of the second agreement, Mr. Fendley accepted the position of Interim Chief Operating Officer effective upon the appointment of Mr. Derkacht as Chief Executive Officer in January 2002. Upon the scheduled termination of the second agreement on March 15, 2002, Mr. Fendley ceased to serve as an executive officer of the Company and has thereafter served exclusively as a member of the Company's Board of Directors.

Severance Compensation Agreements

        The Company has entered into Severance Compensation Agreements (the "Severance Agreements") with certain Named Executive Officers (Mark R. Vipond, Anthony J. Parkinson, Dennis D. Jorgenson and Jeffrey S. Hale) and 12 other employees. The following is a summary of the Severance Agreements, copies of which were attached as Exhibit 10.32 to the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 1999. Terms capitalized in the following summary have the meaning set forth in the Severance Agreements.

        Generally, the Severance Agreements provide that if there is a Change in Control 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, termination by the Company for Cause or the employee's decision to terminate employment other than for Good Reason, the employee will be entitled to receive from the Company certain payments and benefits. These payments and benefits include (1) a lump-sum payment equal to, in the case of one employee, two times the average Compensation of the employee during the two most recent fiscal years of the Company ending prior to the Date of Termination, or in the case of the Named Executive Officers and the other 11 employees, 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; (2) earned but unpaid base salary through the Date of Termination; (3) 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; (4) interest on the amounts described in (1), (2) and (3); and (4) unless the employee's termination of employment is the result of the employee's Disability, 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.

        Compensation payable under the Severance Agreements generally includes compensation includable in the gross income of the employee, but excluding amounts realized on the exercise of

11

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 amounts payable be less than two times the employee's annual rate of base salary at the higher of the annual rate in effect (1) immediately prior to the Date of Termination or (2) on the date six months prior to the Date of Termination.

        Under the Severance 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 Severance 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 Severance 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 Severance Agreements terminate upon the earlier of (1) termination of employment for any reason prior to a Change in Control or (2) three years after the date of a Change in Control.

Non-Compete Agreements

        Each of Messrs. Parkinson, Hale, and Vipond, together with certain other employees of the Company, are parties to the Stock and Warrant Holders Agreement, dated as of December 31, 1993, whereby each has agreed not to compete with the Company for so long as he is employed by the Company. At the election of the Company, the non-compete agreement may be extended for two years after termination of employment provided that, with respect to Messrs. Parkinson and Hale, the Company pays for a period of two years, in accordance with the Company's normal pay periods, 100% of the employee's average annual compensation, defined to be the average annual compensation (consisting of salary and cash compensation pursuant to incentive plans), for the three calendar years preceding the date of termination. The Company may elect to extend the non-compete agreement with respect to Mr.Vipond and one other employee of the company for a period of two years upon the same terms except that the Company is obligated to pay only 50% of the average annual compensation if termination of employment is voluntary or for cause.

REPORT OF THE AUDIT COMMITTEE

        The Company has a standing Audit Committee (the "Audit Committee") of the Board of Directors. During fiscal 2002, the Audit Committee members were Messrs. Kever and Alexander, each having served for the entire fiscal year, Charles E. Noell, III, a former Director who served from the beginning of fiscal 2002 to December 2001, Gregory J. Duman, a former Director who served from January 29, 2002 to May 8, 2002, and Mr. Sanchez, who served from May 8, 2002 to the end of the fiscal 2002. Except for Mr. Duman, each of the Directors was "independent" as defined in Rule 4200(a) of the National Association of Securities Dealers' ("NASD") listing standards. In accordance with the Company's bylaws, and the provisions of NASD Rule 4250 permitting the appointment of one director who is not independent, following the resignation of Mr. Noell in December 2001, the Company appointed Mr. Duman, a former employee who previously served as the Company's Chief Financial Officer, to the Audit

12

Committee on an interim basis pending the appointment of an additional independent director to the Company's Board of Directors. Following the May 2002 appointment of Mr. Sanchez to the Board of Directors and Audit Committee, Mr. Duman resigned from the Audit Committee. The Audit Committee operates pursuant to a charter (the "Audit Committee Charter") approved and adopted by the Board. A copy of the Audit Committee Charter was attached to the Company's proxy statement sent to stockholders with respect to its 2001 Annual Meeting. The Audit Committee held eight meetings during fiscal 2002. Each member of the Audit Committee attended each meeting during the period that he served on the committee.

        The Audit Committee, on behalf of the Board, oversees the Company's financial reporting process. Management is responsible for the Company's internal controls, financial reporting process and compliance with laws and regulations and ethical business standards. The Company's independent accountants are responsible for performing an independent audit of the Company's consolidated financial statements in accordance with auditing standards generally accepted in the United States and to issue a report thereon. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management the audited financial statements and the footnotes thereto in the Company's Annual Report on Form 10-K for fiscal 2002 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 Company's outside independent public accountants, KPMG 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 No. 61, as amended. 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 Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2002, for filing with the Securities and Exchange Commission. The Audit Committee also recommended to the Board of Directors the selection of KPMG LLP to serve as the Company's independent public accountants for the fiscal year ending September 30, 2003.

REPORT OF THE COMPENSATION COMMITTEE

        The Company has a standing Compensation Committee (the "Compensation Committee") of the Board of Directors. The Compensation Committee consisted of Messrs. Kever and Alexander, each having served for all of fiscal 2002, Mr. Fendley, who served from the beginning of fiscal 2002 until August 2002, and Mr. Seymour, who served from August 2002 to the end of the fiscal 2002. The Compensation Committee approves base salary and incentive compensation for, and addresses all other compensation matters with respect to, all executive officers. During fiscal 2002, the Compensation Committee did not hold any meetings in person and acted by unanimous written consent three times.

        The Company's executive compensation program consists 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 the Chief Executive Officer's salary, is based on the recommendation of the Chief Executive Officer 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"). Base salaries recommended are slightly lower than the average of other comparably-sized software companies, based upon the information provided in the Culpepper surveys. 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. The Chief Executive Officer 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. The incentive compensation recommended approximates the average of other comparably-sized software companies, based upon the information provided in the Culpepper surveys. Under the Company's incentive compensation plans, an executive's potential incentive payment is related to the revenue, profit attainment, backlog, cash flow and/or the financial performance of an executive's division or department. The incentive compensation earned during fiscal 2002 by the Company's executive officers slightly exceeded targeted levels established for four executive officers and fell slightly short of targeted levels for the other four executive officers.

        Current CEO's Compensation.    Compensation of the Chief Executive Officer, Mr. Derkacht, who has served as the Company's Chief Executive Officer since January 2, 2002, was based on the same criteria used for executive officers generally, as described above. As compared to industry surveys conducted by Culpepper, Mr. Derkacht's annualized base salary was approximately 28% lower than the average, and his total annualized compensation approximated the average of comparably-sized software companies, based upon the information provided in the Culpepper surveys.

        Interim CEO's Compensation.    Compensation for the Interim Chief Executive Officer, Mr. Fendley, who served as the Company's Interim Chief Executive Officer from May 1, 2001 until January 1, 2002, was based on the same criteria used for executive officers generally. As compared to industry surveys conducted by Culpepper, Mr. Fendley's annualized base salary was approximately 11% lower than the

14

average and his total annualized compensation approximated the average of comparably-sized software companies, based upon the information provided in the Culpepper surveys.

        Stock Option Exchange Offer.    On August 1, 2002, the Company announced a voluntary stock option exchange program offering to exchange all outstanding options to purchase shares of the Common Stock granted under the Company's 1994 Stock Option Plan, 1996 Stock Option Plan and 1999 Stock Option Plan, collectively referred to in this report as the "Option Plans." The Option Plans are intended to provide retention and performance incentives for employees and Directors. The Board of Directors, including members of the Compensation Committee serving at that time, determined that the vast majority of the options outstanding under the Option Plans, whether or not they were then currently exercisable, had exercise prices that were significantly higher than the then current market price of the Common Stock. The Board recognized that the options were unlikely to be exercised in the foreseeable future and determined that the Company should provide its employees and Directors with the benefit of owning options that over time may have a greater potential to increase in value, create better retention and performance incentives for those individuals and thereby maximize stockholder value. Accordingly, the Board authorized the Company to tender an offer to exchange outstanding options for new options that were designed to (1) have an exercise price equal to the fair market value of the Common Stock on the date that the Company granted new options and (2) begin vesting one month after the grant date. However, in order to assure that the option exchange program served its primary purposes of assuring the continued service of key employees and Directors and helping to create stockholder value, several limitations were imposed. First, no participant was eligible to receive a replacement option for his or her cancelled option unless that individual continued in the Company's employment until the grant date of the replacement option. Also, the program was designed to comply with FASB Interpretation No. 44 for fixed plan accounting. The Board believed that the program struck an appropriate balance between the interests of the Company's employees and Directors and those of the shareholders.

        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. 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 members of the Compensation Committee during the fiscal 2002 were Messrs. Alexander, Kever, Fendley and Seymour. Except for Mr. Fendley, who was an officer of the Company from the beginning of fiscal 2002 until March 15, 2002, none of these individuals was at any time during fiscal 2002, 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.

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 Annual Meeting, it is intended that the proxies in the accompanying form will be voted as the persons named therein may determine in their discretion.

16

Independent Accountants

        The Audit Committee of the Company's Board of Directors annually considers and recommends to the Board the selection of its independent public accountants. On May 29, 2002, as recommended by the Company's Audit Committee, the Board of Directors decided to no longer engage Arthur Andersen LLP ("Arthur Andersen") as the Company's independent public accountants and engaged KPMG LLP to serve as its independent public accountants for the fiscal year ending September 30, 2002.

        Arthur Andersen's reports on the Company's consolidated financial statements for the past two fiscal years did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

        During the Company's two most recent fiscal years and through May 29, 2002, there were no disagreements with Arthur Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Arthur Andersen's satisfaction, would have caused them to make reference to the subject matter in connection with their report on the Company's consolidated financial statements for such years; and there were no reportable items as defined in Item 304(a)(1)(v) of Regulation S-K.

        The Company provided Arthur Andersen with a copy of the foregoing disclosures. Arthur Andersen provided a letter, dated June 5, 2002, stating its agreement with such statements.

        During the two most recent fiscal years and through May 29, 2002, TSA did not consult KPMG LLP with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's consolidated financial statements, or any other matters or reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

        Audit Fees.    The aggregate fees billed by KPMG LLP for professional services rendered for the audit of the Company's annual consolidated financial statements for fiscal 2002 and the re-audit of the Company's annual consolidated financial statements for fiscal 2001 and 2000 totaled approximately $3.0 million.

        Financial Information Systems Design and Implementation Fees.    There were no fees billed by KPMG LLP for professional services rendered for information technology services relating to financial information systems design and implementation for fiscal 2002.

        All Other Fees.    The aggregate fees billed by KPMG LLP for services rendered to the Company, other than the services described above under "Audit Fees" and "Financial Information Systems Design and Implementation Fees," for fiscal 2002 totaled approximately $90,000.

        The Audit Committee has considered whether the provision of the services by KPMG LLP, as described above in "All Other Fees," is compatible with maintaining the principal accountant's independence.

        Representatives of KPMG LLP are expected to be present at the Annual Meeting, to make a statement should they so desire and to respond to appropriate questions.

Stockholder 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 26, 2003, to be considered for inclusion in the proxy statement and form of proxy for that meeting.

17

        Pursuant to Rule 14a-4(c) under the Exchange Act, 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, the proxies solicited by the Company may confer discretionary voting authority to vote 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 (1) 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, (2) the name and address, as they appear on the Company's books, of the stockholder proposing such business, (3) the class and number of shares of the Company which are beneficially owned by the stockholder, and (4) 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 Annual Meeting, and if he should so determine, such business shall not be transacted.
