Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding in their names shares of Common Stock beneficially owned by others to forward to such beneficial owners. The Company may reimburse persons representing beneficial owners of Common Stock for their costs of forwarding solicitation materials to such beneficial owners. Original solicitation of proxies by mail may be supplemented by telephone, telegram or personal solicitation by directors, officers or other regular employees of the Company. No additional compensation will be paid to directors, officers or other regular employees for such services.

If the proxy is signed and returned without any direction given, shares will be voted in accordance with the Board of Directors' recommendations. All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes. Abstentions will be counted towards the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes.

The exercise price equals the fair market value on the day prior to the date of grant based on the closing price of the Common Stock as quoted on the Nasdaq National Market. (2) In 1999, the Company granted 4,288,890 stock options to employees under its 1997 Stock Option Plan, and 192,487 stock options to employees under its 1999 Equity Incentive Plan. (3) Assumes all options are exercised at the end of their respective 10-year terms. The dollar amounts under these columns are the result of calculations at the 5% and 10% rates required by applicable regulations of the Securities and Exchange Commission and, therefore, are not intended to forecast possible future appreciation, if any, of the Common Stock price. Actual gains, if any, on stock option exercises depend on the future performance of the Common Stock and overall stock market conditions, as well as the option holders continued employment through the vesting period. The amount reflected in this table may not necessarily be achieved. (4) Options granted to Scott Fox contain a provision for accelerated vesting based upon the performance of the Company's stock. Such provision had been satisfied in January 2000, which vested 174,167 options at that time, and accelerated vesting for the remaining options by one year. These options also contain accelerated vesting upon the occurrence of a change of control. Such change of control is deemed to have occurred upon: merger or sale of the Company, sale, transfer or disposition of substantially all Company assets, reverse merger which distributes at least 50% of the outstanding stock to outside shareholder, sale, transfer or other distribution of shares beneficially held by any Tayebi family member to outside holders, shall accelerate vesting based on predetermined dates when such change of control shall have occurred. Such options also carry accelerated vesting clauses based upon termination by the Company by named dates. (5) Mr. Sackley terminated his position with the Company in January of 2000. None of the options shown above were exercised. 12

EMPLOYMENT AGREEMENTS In connection with his employment, on April 9, 1999, the Company entered into a letter agreement with Scott Fox, President of Network Management. Under the letter agreement, Mr. Fox's annual salary is $225,000 and he is eligible for a minimum annual bonus of 35% of his base salary. The letter agreement also provides for a $225,000 signing bonus, which is payable in two parts, and guaranteed appreciation of at least $600,000 on 25% of his stock options. In the event that the Company terminates Mr. Fox within the first two years of his employment, certain of Mr. Fox's unvested options will become fully vested and exercisable and, at his option, the Company will owe him either $112,500 or 20,455 shares of common stock, in connection with his signing bonus. In the event of a change in control of WFI within the first two years of Mr. Fox's employment, all of his unvested stock options will become fully vested and exercisable and a signing bonus of $112,500 will be due and payable. In the event of a change in control of WFI after the first two years of Mr. Fox's employment, 50% of his unvested stock options will vest immediately and become exercisable. In July 1999, the Company loaned Mr. Fox $169,000 at an interest rate of 6% per year in connection with a mortgage on his house. COMPENSATION COMMITTEE REPORT (1) During 1999, the Compensation Committee of the Board of Directors (the "Committee") included Bandel Carano, Scot Jarvis and Scott Anderson. All committee members are non-employee directors of the Company and have never served as officers of the Company. The Committee is responsible for administering the Company's compensation and employee benefit plans, which include primarily the 1997 Stock Option Plan, the 1999 Equity Incentive Plan and the 1999 Employee Stock Purchase Plan. In addition to setting policies regarding compensation of all employees, the Committee reviews and approves base salaries and bonuses for all executive officers. Decisions made by the Committee relating to compensation of executive officers are reviewed by the full Board of Directors. Executive Compensation Policies and Performance Measures The Company's executive compensation policies have been developed to meet the following objectives: . Attract and retain key executives critical to the Company's long-term success; . Reward key executives for their contributions to the development and successful execution of strategies relevant to their functional responsibilities; and . Motivate key executives to make decisions and take actions that achieve the Company's strategic performance goals and increase the long-term value of the Common Stock. The Committee uses a combination of cash and equity-based programs to compensate key executives. Compensation payments in excess of $1 million to each of the Chief Executive Officer or four other most highly compensated executive officers are subject to a limitation on deductibility for the Company under Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"). Certain performance-based compensation is not subject to the limitation on deductibility. The Committee does not expect cash compensation in 1999 to the Chief Executive Officer or any other executive officer to be in excess of $1 million. The Option Plans are designed to qualify stock option awards for the performance-based exception to the $1 million limitation on deductibility of compensation payments. - -------- (1) This Section is not "soliciting material," is not deemed "filed" with the SEC and is not to be incorporated by reference in any filing of the Company under the 1933 Act or the 1934 Act whether made before or after the date hereof and irrespective of any general incorporation language in any such filing. 14

Cash-based Compensation Base salaries for all executive officers are reviewed annually. In evaluating executive salaries, the Committee considers the compensation paid at companies of similar size in its industry, as well as the Company's own recent recruiting experience, if applicable. The companies surveyed include some, but not all, of the companies in the Nasdaq Telecommunications Index used in the Stock Price Performance graph. The Committee also considers the officer's individual performance during the prior year. Factors that affect an individual officer's performance rating focus on the executive's success in contributing to the Company's short and long-term objectives. Short-term objectives include gross profit and gross margin, operating income and operating income margin, and net earnings and net earnings margin. Long-term objectives include the timely development of new service offerings, enhancements and improvements to existing service offerings, identification of new markets for the Company's services, development and execution of plans to address identified market opportunities, adequate control over and efficient use of the Company's assets, and share price appreciation. The Company does not assign relative weights to the factors it considers in establishing base salaries. In addition to base salary, the Company provides executive officers and other key managers incentive compensation in the form of annual discretionary basis bonuses of cash or options to purchase common stock in the Company. Equity-based Compensation The Company provides its executive officers with long-term incentives through its option plans. The option plans' primary objective is to provide an incentive for the executive officers to make decisions and take actions that maximize long-term stockholder value. Each plan promotes this long-term focus using vesting periods. Options currently generally vest in over four years from the date of grant, 25% on the first anniversary of the date of grant and the balance vesting monthly over the remaining three years. The Committee reviews and approves all grants made to officers of the Company under the option plans and in connection with initial hiring, promotions, extraordinary achievements or compensation adjustments. In addition to these factors, the size and timing of grants are generally subject to policies established by the Committee regarding the position of the grantee within the Company, the overall number of options actually granted to such optionee in the past, and the extent of vesting of such grants. Chief Executive Officer Compensation In establishing the Chief Executive Officer's compensation package, the Committee pursues the same objectives and policies that apply for the Company's other executive officers. However, it is not the Company's practice to pay cash or non-cash bonuses to its Chief Executive Officer, who is a founder and significant stockholder of the Company. As such, no cash or bonus options have been given to the Company's Chief Executive Officer. Compensation Committee Scott Anderson Scot Jarvis Bandel Carano 15

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS The following is a description of transactions since January 1, 1999 to which the Company has been a party, in which the amount involved exceeds $60,000 and in which any director, officer, executive officer or holder of more than 5% of our capital stock had or will have a direct or indirect material interest, other than the Company's compensation arrangements with its directors and named executive officers that are listed above. From January 1, 1999 through June 30, 1999, the Company advanced an aggregate of $221,518 to Masood Tayebi which amount he repaid on September 28, 1999. In June 1999, the Company sold to Masood Tayebi and Massih Tayebi its 25% ownership interest in Sierra Towers Investment Group, LLC, an early stage tower company operating in Mexico. At the time, the Company's officers and a disinterested member of the Board of Directors determined that the Company's membership units in Sierra and Sierra's promissory note owed to the Company had a cumulative fair value of $262,348 as of the date of the transaction. A majority of the disinterested members of the Board of Directors ratified the transaction in August 1999. Masood Tayebi and Massih Tayebi each purchased one half of the Company's ownership interest in Sierra, paying the fair value for such interest with promissory notes which bear interest at a rate of 10% per annum and are due and payable on November 30, 1999. These notes have not been repaid as of 3/31/2000. Prior to June 30, 1999 the Company contracted with Total Outsourcing, Inc., a company owned by Massih Tayebi's wife, for the leasing of computer equipment, apartments, vehicles and other items. The Company has terminated its contract and has entered into a Settlement Agreement and Mutual General Release with Total Outsourcing effective as of June 30, 1999. Pursuant to this Settlement Agreement, the Company paid $258,091 to Total Outsourcing in February 2000 as repayment in full. From April 1999 through February 2000, the Company subleased approximately 4,900 square feet of office space in its headquarters facility to QuantumThink Group, Inc., a technology outsourcing company which is majority-owned by the Tayebi family. QuantumThink Group's tenancy was month-to-month. QuantumThink Group paid monthly rent of $4,500, which is more than the Company's pro rated rent expense for such space. The Company believes that the rent paid by QuantumThink Group is comparable to rents that could be obtained from unaffiliated third parties for such space. A member of the Company's Board of Directors, Scott Anderson, is a member of the boards of directors of Triton PCS, Telecorp and TriTel, all of which are customers of the Company. In addition, Scot Jarvis, a member of the Company's Board of Directors, is a member of the board of directors of Leap Wireless International, which is also a customer of the Company. Another member of the board of directors, Bandel Carano, is a member of the Company's Board of Directors of Advanced Radio Telecom Corp., which is also a customer of the Company. Prior to August 1999, the Company paid $5,000 per month to Cedar Grove Partners in consideration of the services rendered to the Company by Scott Anderson and Scot Jarvis as directors of the Company. Messrs. Anderson and Jarvis are the general partners of Cedar Grove Partners. The Company's obligation to make these payments terminated in August 1999. On January 6, 2000, the Company loaned Michael Brink $94,800 at an annual interest rate of 8% (interest due on a monthly basis) toward the purchase of 60,000 shares underlying his vested options. The principal and all unpaid interest amounts on the loan are due on January 7, 2001. On November 24, 1999, the Company repaid $5,500,000 of stockholder loans issued to Masood Tayebi, Massih Tayebi and Sean Tayebi. The notes were previously issued in 1998 in conjunction with the issuance of a dividend of $0.19 per share. On January 21, 2000, the Company entered into an agreement with Chuck Sackley, the Company's Senior Vice President of Sales and Business Development at the time. The Company loaned Mr. Sackley $432,941 17

towards the payment of taxes associated with his exercise of certain non- qualified stock options. This amount is to be repaid in full by Mr. Sackley on May 6, 2000 after the end of the underwriter's lock-up of the Company's common stock. The Company has entered into indemnity agreements with each of its officers and directors which provide, among other things, that the Company will indemnify such officer or director, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines and settlements he may be required to pay in actions or proceedings which he is or may be made a party be reason of his position as a director, officer or other agent of the Company, and otherwise to the full extent permitted under Delaware law and the Company's Bylaws. In addition, the Company's restated certificate of incorporation provides that its directors will not be personally liable to the Company or its stockholders for monetary damages for any breach of fiduciary duty as a director, except for liability: (1) for any breach of the director's duty of loyalty to the Company or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the Delaware General Corporation Law, or (4) for any transaction from which the director derives an improper personal benefit.
