MEETINGS OF STOCKHOLDERS Section 1. - Place of Meetings. Meetings of stockholders shall be held -------------------------------- at any place within or outside the State of Delaware designated by the Board of Directors. In the absence of any such designation, stockholders' meetings shall be held at the principal executive office of the corporation. Section 2. - Annual Meeting. The annual meeting of the stockholders ----------------------------- shall be held each year within six (6) months of the end of the corporation's fiscal year on a date and at a time designated by the Board of Directors. If this day shall be a legal holiday, then the meeting shall be held on the next succeeding business day, at the same hour. At the annual meeting, the stockholders shall elect a Board of Directors, consider reports of the affairs of the corporation and transact such other business as may be properly brought before the meeting. Section 3. - Special Meeting. Special meetings of the stockholders, for ------------------------------ any purpose or purposes, unless otherwise prescribed by statute or the Certificate of Incorporation, may be called at any time by the President, and shall be called by the President or Secretary at the request in writing of a majority of the Board of Directors or one or more stockholders owning a majority in amount of the entire capital stock of the corporation issued and outstanding and entitled to vote. The written request shall state the purpose or purposes of the special meeting. Business transacted at any special meeting shall be limited to the purposes stated in the notice. Section 4. - Notice of Stockholders' Meetings. Whenever stockholders are ----------------------------------------------- required or permitted to take any action at a meeting, a written notice of the meeting shall be given which notice shall state the place, date and hour of the meeting, and, in the case of a special meeting, 1

the purpose or purposes for which the meeting is called. The written notice of any meeting shall be given to each stockholder entitled to vote at such meeting not less than 10 nor more than 60 days before the date of the meeting. If mailed, notice is given when deposited in the United States mail postage prepaid, directed to the stockholder at his address as it appears on the records of the corporation. An affidavit of the mailing or other means of giving any notice of any stockholders' meeting shall be executed by the Secretary, Assistant Secretary or any transfer agent of the corporation giving the notice, and shall be filed and maintained in the minute book of the corporation and shall, in the absence of fraud, be prima facie evidence of facts stated herein. Section 5. - Quorum. The presence in person or by proxy of the holders --------------------- of a majority of the stock issued and outstanding and entitled to vote at any meeting of stockholders shall constitute a quorum for the transaction of business. Section 6. - Adjourned Meeting; Notice. Any stockholders' meeting, ---------------------------------------- annual or special, whether or not a quorum is present, may be adjourned from time to time by the vote of the majority of the shares represented at that meeting, either in person or by proxy, but in the absence of a quorum, no other business may be transacted at that meeting. When any meeting of stockholders, either annual or special, is adjourned to another time or place, notice need not be given of the adjourned meeting if the time and place are announced at a meeting at which the adjournment is taken, unless the adjournment is for more than 30 days from the date set for the original meeting, or if after adjournment a new record date is fixed for the adjourned meeting. Notice of any such adjourned meeting shall be given to each stockholder of record entitled to vote at the adjourned meeting in accordance with Section 4 of this Article II. At any adjourned meeting the corporation may transact any business which might have been transacted at the original meeting. Section 7. - Voting; Proxies. The stockholders entitled to vote at any ------------------------------ meeting of stockholders shall be determined in accordance with the provisions of Section 11 of this Article II, subject to the provisions of Section 217 of the Delaware General Corporation Law (relating to voting shares held by a fiduciary or in joint ownership). Except as otherwise provided by the Certificate of Incorporation, each stockholder entitled to vote at any meeting of stockholders shall be entitled to one vote for each share of stock held by him which has voting power upon the matter in question. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for him by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. All proxies must be filed with the Secretary of the corporation at the beginning of each meeting in order to be counted. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with the Secretary of the corporation. Unless otherwise required under these bylaws or the Delaware General Corporation Law, voting at meetings of stockholders need not be by written ballot and need not be conducted by inspectors of election unless so determined by the holders of shares of stock owning a majority in amount of the entire capital stock of the corporation issued and outstanding and entitled to vote which are present in person or by proxy at such meeting. At any stockholder meeting at which a quorum is present, the affirmative vote 2

of a majority of the stock issued and outstanding and entitled to vote at any meeting of stockholders shall be the act of the stockholders, unless the vote of a greater number or voting by classes is required by the Delaware General Corporation Law or by the Certificate of Incorporation. There shall be no cumulative voting. Section 8. - Record Date for Stockholder Notice, Voting and Giving -------------------------------------------------------------------- Consents. For purposes of determining the stockholders entitled to notice of - -------- any meeting or to vote or entitled to give consent to corporate action without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors and which record date shall not be more than 60 days nor less than 10 days before the date of any such meeting nor more than 10 days before any such action without a meeting. If the Board of Directors does not so fix a record date: (a) The record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the business day next preceding the day on which notice is given or, if notice is waived, at the close of business on the business day next preceding the day on which the meeting is held. (b) The record date for determining stockholders entitled to give consent to corporate action in writing without a meeting (i) when no prior action by the Board has been taken, shall be the day on which the first written consent is given, or (ii) when prior action of the Board has been taken, shall be at the close of business on the day on which the Board adopts the resolution relating to that action. Section 9. - List of Stockholders Entitled to Vote. The officer who has ---------------------------------------------------- charge of the stock ledger of the corporation shall prepare and make, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. Such list shall be open to examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified in the notice of the meeting or if no notice is given, at the place where the meeting is to be held. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. Section 10. - Telephonic Meetings. At any meeting held pursuant to these ----------------------------------- Bylaws, shareholders may participate by means of a telephone conference or similar method of communication by which all persons participating in the meeting can hear each other. Participation in such a meeting constitutes presence in person at the meeting. Section 11. - Stockholder Action by Written Consent Without a Meeting. ----------------------------------------------------------------------- Any action which may be taken at any annual or special meeting of stockholders may be taken without a meeting and without prior notice, if a consent in writing, setting forth the action so taken, is signed by the holders of outstanding shares having not less than the minimum number of votes 3

that would be necessary to authorize or take that action at a meeting at which all shares entitled to vote on that action were present and voted. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those stockholders who have not consented in writing. Section 12. - Inspectors of Election. Before any meeting of -------------------------------------- stockholders, the corporation shall appoint one or more inspectors of election to act at the meeting if so required under Section 7 of this Article II and make a written report thereon. If no inspectors of election are able to act at a meeting of the stockholders, the Chairman of the meeting shall appoint one or more inspectors of election to act at the meeting. If inspectors are appointed at a meeting, the holders of a majority of shares or their proxies present at the meeting shall determine how many inspectors are to be appointed. If any person appointed as inspector fails to appear or fails or refuses to act, the Chairman of the meeting shall appoint a person to fill that vacancy. These inspectors shall: (a) Determine the number of shares outstanding and the voting power of each, the shares represented at the meeting, the existence of a quorum and the authenticity, validity and effect of proxies; (b) Hear, determine and retain for a reasonable period a record of the disposition of all challenges and questions in any way arising in connection with the right to vote; (c) Count and tabulate all votes or consents; (d) Determine when the polls shall close; (e) Determine the result. ARTICLE III. DIRECTORS Section 1. - Powers. Subject to the provisions of the Delaware General --------------------- Corporation law and any limitations in the Certificate of Incorporation and these Bylaws relating to action required to be approved by the stockholders or by the outstanding shares, the business and affairs of the corporation shall be managed and all corporate powers shall be exercised by or under the direction of the Board of Directors. Section 2. - Number of Directors. The number of directors of the ---------------------------------- corporation shall not be less than three (3) nor more than seven (7). The exact number of directors shall be four (4) until changed, within the limits specified above, by a bylaw amending this Section 2, duly adopted by the board of directors or by the shareholders. The indefinite number of directors may be changed, or a definite number fixed without provision for an indefinite number, by a duly adopted amendment to the articles of incorporation or by an amendment to this bylaw duly adopted by the vote or written consent of holders of a majority of the outstanding shares entitled to vote. 4

Section 3. - Vacancies. Vacancies in the Board of Directors may be ------------------------ filled by a majority of the remaining directors, though less than a quorum, or by a sole remaining director. Each director so elected shall hold office until the next annual meeting of the stockholders and until a successor has been elected and qualified. A vacancy or vacancies in the Board of Directors shall be deemed to exist in the event of the death, resignation, disqualification or removal of any director, or otherwise. Any director may resign effective on giving written notice to the corporation. If no directors are in office, then an election of directors may be held in the manner provided in statute. If, at the time of filling any vacancy or newly created directorship, the directors then in office shall constitute less than a majority of the whole Board (as constituted immediately prior to any such increase), the Court of Chancery of the State of Delaware may, upon application of any stockholder or stockholders holding at least ten percent (10%) of the total number of the shares of stock at the time outstanding having the right to vote for such directors, summarily order an election to be held to fill any such vacancies or newly created directorships, or to replace the directors chosen by the directors then in office. Any director may resign effective on giving written notice to the Chairman of the Board, the President, the Secretary or the Board of Directors, unless the notice specifies a later time for that resignation to become effective. If the resignation of a director is effective at a future time, the Board of Directors may elect a successor to take office when the resignation becomes effective. No reduction of the authorized number of directors shall have the effect of removing any director before that director's term of office expires. Section 4. - Regular and Special Meetings; Place of Meetings; Notice; ----------------------------------------------------------------------- Meetings by Telephone. Regular meetings of the Board of Directors may be held - --------------------- without call and at any place within or outside the State of Delaware that has been designated from time to time by resolution of the Board. Such meetings may be held without notice. In the absence of such a designation, regular meetings shall be held at the principal executive office of the corporation. Special meetings of the Board may be called by the President, any Vice President, the Secretary or any member of the Board of Directors and shall be held at any place within or outside the State of Delaware that has been designated in the notice of the meeting or, if not stated in the notice or if no notice is given, at the principal executive office of the corporation. Notice of a special meeting shall be given by the person or persons calling the meeting at least 24 hours before the special meeting. Any meeting, regular or special, may be held by conference telephone or similar communication equipment, so long as all directors participating in the meeting can hear one another, and all such directors shall be deemed to be present in person at the meeting.

Section 9. - Indemnification. ------------------------------ (a) The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. (b) The corporation shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and except that no such indemnification shall be made in respect of 6

any claim, issue or matter as to which such person shall have been adjudged to be liable for negligence or misconduct in the performance of his duty to the corporation unless and only to the extent that the Court of Chancery of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such Court of Chancery or such other court shall deem proper. (c) To the extent that a director, officer, employee or agent of the corporation shall be successful on the merits or otherwise in defense of any action, suit or proceeding referred to in paragraphs (a) and (b), or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. (d) Any indemnification under paragraphs (a) and (b) (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in paragraphs (a) and (b). Such determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to such action, suit or proceeding, or (2) if such a quorum is not obtainable, or, even if obtainable a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (3) by the stockholders. (e) Expenses incurred in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the manner provided in paragraph (d) upon receipt of an undertaking by or on behalf of the director, officer, employee or agent to repay such amount unless it shall ultimately be determined that he is entitled to be indemnified by the corporation as authorized in this Section 9. (f) The indemnification provided by this Section 9 shall not be deemed exclusive of any other rights to which those indemnified may be entitled under any Bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in his official capacity and as to action in another capacity while holding such office, and shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. (g) The Board of Directors may authorize the corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under the provisions of this Section 9. (h) For the purposes of this Section 9, references to "the corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate 7

existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section 9 with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued. (i) For purposes of this section, references to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the corporation" shall include service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner he reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interests of the corporation" as referred to in this Section 9.

This bylaw may be amended or repealed either by a duly authorized action of the Board of Directors or by the stockholders, upon the express written consent of the owners of a majority of the voting power of the corporation.

Optionee agrees that he will not sell or ---------------------- otherwise transfer any Option Shares (including transfer by operation of law) at any time after the expiration of the Right of Repurchase and prior to the termination of this section pursuant to Section 9(d) below unless such Option Shares shall first be offered to the Company as follows: (a) The Optionee shall deliver a notice (the "Notice") to the Company, stating (i) the Optionee's bona fide intention to sell or transfer such Option Shares, (ii) the number of such Option Shares to be sold or transferred, (iii) the consideration for which the Optionee proposes to sell or transfer such Option Shares, (iv) the terms of payment of such consideration and any other terms and conditions of sale, and (v) the name of the proposed purchaser or transferee. (b) Within thirty (30) days after receipt of the Notice, the Company may elect to purchase any or all of the Option Shares to which the Notice refers, for the consideration per share and upon the terms and conditions specified in the Notice, except as set forth in Section 8(e) below for transfers involving non-cash consideration. If the Company elects not to purchase all such Option Shares, the Company may assign its right to purchase the remaining Option Shares. The Company's assignees may elect, within thirty (30) days after receipt by the Company of the Notice, to purchase any or all Option Shares to which the Notice refers which the Company has not elected to purchase, for the consideration per share and upon the terms and conditions specified in the Notice, except as set forth in Section 8(e) below. An election to purchase shall be made by written notice to the Optionee, specifying the number of Option Shares to be purchased. If the Company and/or its assignees elect to purchase the offered Option Shares, they shall complete the purchase within sixty (60) days after receipt by the Company of the Notice, unless a longer period is set forth in the Notice. (c) If the Company and/or its assignees do not elect to so purchase all of such offered Option Shares within such thirty (30) day period, Optionee shall have no obligation to transfer such Option Shares to the Company and/or its assignees and the Optionee shall have a period of thirty (30) days thereafter to transfer all (but not less than all) of such Option Shares to the transferee referred to in the Notice and for the same consideration and on the other terms as set forth therein; provided, however, that prior to any transfer of such Option Shares, the proposed transferee shall execute and deliver to the Company an agreement with the Company, in form and substance satisfactory to the Company, pursuant to which such transferee agrees to be subject to the relevant provisions of the Option Agreement. (d) In the event that such Option Shares are not transferred to the transferee referred to in the Notice and in accordance with the terms of the Option Agreement within such 30- 4.

day period, the restrictions on transfer provided in this Section 8 shall again become applicable to the Option Shares. (e) If part or all of the purchase consideration specified in a Notice delivered by the Optionee pursuant to this Section 8 is other than cash or purchaser's promissory note or other evidence of indebtedness, the Company and its assignee(s) shall have the right to purchase the Option Shares specified in the Notice for a cash price equal to the fair market value of the number of Option Shares to be so purchased by the Company and/or its assignee(s). The fair market value of any Option Shares shall be as determined in good faith by the Company's Board of Directors (or an officer appointed by the Board of Directors for such purposes). 9. Other Provisions Regarding Transfer. ------------------------------------ (a) Optionee, as a condition for accepting any Option Shares, shall not sell, transfer or pledge any Option Shares subject to the Right of Repurchase described in Section 7 or the right of first refusal described in Section 8 hereof, other than in the manner expressly permitted in the Option Agreement, and any such sale, transfer or pledge of the Option Shares in violation of this Agreement shall be void. The Company shall not be required (i) to transfer on its books any Option Shares which shall have been sold or transferred in violation of any of the provisions set forth in the Option Agreement or (ii) to treat as the owner of such Option Shares or accord the right to vote or pay dividends to any transferee to whom such Option Shares shall have been so transferred. (b) Notwithstanding anything to the contrary contained herein, Optionee is under no restrictions as to the transfer by him of any or all of the issued Option Shares to his Related Transferees (as defined herein) provided that each such Related Transferee shall first (i) execute a written consent to be bound by all of the relevant provisions of the Option Agreement in form and substance satisfactory to the Company and (ii) give a duplicate original of such consent to the Company. The "Related Transferees" of the Optionee as used herein shall consist of the Optionee's spouse, his adult lineal descendants, the adult spouses of his lineal descendants and trusts for the benefit of any of the foregoing, Optionee and/or his minor lineal descendants. In the event of any transfer by the Optionee to his Related Transferees of all or any part of the Option Shares (or in the event of any subsequent transfer by any such Related Transferee to another Related Transferee of the Optionee), such Related Transferees shall receive and hold the Option Shares subject to the relevant terms of the Option Agreement and the Optionee's rights and obligations hereunder as though the Option Shares were still owned by the Optionee and shall together with the Optionee continue to be deemed to be the "Optionee" for purposes of the Option Agreement, including without limitation restrictions on the transfer of Option Shares. There shall be no further transfer of the Option Shares by a Related Transferee except between and among such Related Transferee, the Optionee and other Related Transferees of the Optionee, or except as permitted by the Option Agreement. The Company advises the Optionee to seek independent tax counsel prior to transferring any Option Shares to any Related Transferee. (c) The Optionee hereby grants to the Company a security interest in the Option Shares for the purpose of ensuring that a transfer in violation of the restrictions set forth in Sections 7, 8 and 9 of this Agreement does not occur. In furtherance of such security interest, the Company 5.

may, at its option, retain the certificate(s) evidencing the Option Shares, together with stock assignments executed in blank by the Optionee, until such transfer restrictions terminate in accordance with Section 9(d). The Optionee hereby grants to any officer(s) of the Company the power of attorney to cause the Option Shares to be transferred on the books of the Company in the event the Company and/or its assignees repurchase some or all of the Option Shares in accordance with the Option Agreement. (d) The transfer restrictions provided in Sections 7, 8 and 9 hereof shall terminate upon the earlier to occur of (i) the effectiveness of a registration statement (other than a registration statement pursuant to any employee, purchase, savings, option, bonus, appreciation, profit sharing, thrift, incentive or similar plan of the Company) filed by the Company under the Securities Act in connection with the initial public offering of its securities, and the completion of the sale of securities made pursuant to such registration statement for an aggregate amount of at least $10,000,000, and (ii) such other conditions as the Board of Directors may determine in its sole discretion. 10. Notice of Tax Election. If Optionee makes any tax election relating ---------------------- to the treatment of the Option Shares under the Internal Revenue Code of 1986, as amended, Optionee shall promptly notify the Company of such election. 11. Market Stand-Off. ---------------- (a) In connection with any underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under the Securities Act, including the Company's initial public offering, Optionee shall not sell, make any short sale of, loan, hypothecate, pledge, grant any option for the purchase of, or otherwise dispose of or transfer for value or otherwise agree to engage in any of the foregoing transactions with respect to any of the Option Shares without the prior written consent of the Company and its underwriters, for such period of time from and after the effective date of such registration statement as may be requested by the Company or such underwriters, which period of time shall not exceed one hundred eighty (180) days. (b) Notwithstanding the foregoing, Optionee shall be subject to the market stand-off provisions of this Section 11 only if the executive officers and directors of the Company are also subject to similar arrangements which are no less restrictive. (c) In order to enforce the provisions of this Section 11, the Company may impose stop-transfer instructions with respect to the Option Shares until the end of the applicable stand-off period. 12. Acknowledgments of Optionee. Optionee acknowledges and agrees that: --------------------------- (a) Although the Company has made a good faith attempt to qualify the Option as an incentive stock option within the meaning of Sections 421, 422 and 424 of the Code, the Company does not warrant that the Option granted herein constitutes an "incentive stock option" 6.

within the meaning of such sections, or that the transfer of Option Shares will be treated for federal income tax purposes as specified in Section 421 of the Code. (b) Optionee shall notify the Company in writing within fifteen (15) days of each disposition (including a sale, exchange, gift or a transfer of legal title) of the Option Shares made within three years after the issuance of such Option Shares. (c) Optionee understands that if, among other things, he disposes of any Option Shares granted within two years of the granting of the Option to him or within one year of the issuance of such shares to him, then such Option Shares will not qualify for the beneficial treatment which Optionee might otherwise receive under Sections 421 and 422 of the Code. (d) Optionee and his transferees shall have no rights as a shareholder with respect to any Option Shares until the date of the issuance of a stock certificate evidencing such Option Shares. No adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property) or distributions or other rights for which the record date is prior to the date such stock certificate is issued, except as provided in Section 9 of the Plan. (e) All certificates representing the Option Shares shall have endorsed thereon the following legends, the provisions of which are hereby incorporated into the Option Agreement: THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR THE SECURITIES LAWS OF ANY STATE OTHER THAN THE STATE OF CALIFORNIA AND HAVE BEEN ISSUED AND SOLD PURSUANT TO AN EXEMPTION FROM THE ACT AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED BY THE HOLDERS THEREOF AT ANY TIME EXCEPT (1) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FILED UNDER THE ACT COVERING THE SECURITIES, OR (2) IF, IN THE REASONABLE OPINION OF COUNSEL TO THE CORPORATION, SUCH SHARES MAY BE TRANSFERRED WITHOUT SUCH REGISTRATION. IN ADDITION, SALE, TRANSFER OR HYPOTHECATION OF THIS SECURITY IS RESTRICTED BY THE PROVISIONS OF AN INCENTIVE STOCK OPTION AGREEMENT (AND THE STANDARD TERMS AND CONDITIONS RELATING TO INCENTIVE STOCK OPTIONS INCORPORATED THEREIN) ENTERED INTO BY THE CORPORATION AND THIS SHAREHOLDER DATED AS OF _________________ [AGREEMENT DATE], A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICE OF THE CORPORATION AND ALL 7.

OF THE PROVISIONS OF WHICH ARE INCORPORATED HEREIN.

THIS LEGEND SHALL NOT APPEAR ON THE CERTIFICATES ISSUED UPON TRANSFER OF THESE SHARES. 13. Investment Representations. As an inducement to the Company to grant -------------------------- the Option and issue the Option Shares to the Optionee, the Optionee hereby makes the following representations and warranties, and authorizes the Company to rely upon the same: (a) The Optionee will acquire the Option Shares for investment for his own account, not for resale, without any intention of or view toward or for participating, directly or indirectly, in a distribution of the Option Shares or any portion thereof. (b) The Optionee understands that an investment in the Company is speculative, that any possible profits therefrom are uncertain, and that he must bear the economic risks of the investment in the Company for an indefinite period of time. (c) The Optionee understands that the Option Shares have not been registered under the Securities Act in reliance on the exemption provided by Rule 701 promulgated thereunder for compensatory benefit plans; and that the Option Shares have not been registered or qualified under the "blue sky" laws of any state including the State of California. (d) The Optionee understands that the Option Shares may have to be held indefinitely unless they are subsequently registered under the Securities Act and qualified or registered under other applicable securities laws, rules and regulations, which is unlikely, or unless an exemption from such qualification or registration is available. (e) The Optionee understands and agrees that (i) the legends set forth in Section 12(e) hereof will be placed on the certificate(s) evidencing the Option Shares and, except as otherwise provided in Section 12(e), on certificate(s) issued to transferees; (ii) the stock records of the Company will be noted with respect to such restrictions; (iii) the Company will not be under any obligation to register the Option Shares or to comply with any exemption available for sale of the Option Shares without registration; and (iv) the information or conditions necessary to permit routine sales of securities of the Company under Rule 144 of the Securities Act are not now available and it is not likely that they will become available in the foreseeable future. 8.

(f) The Optionee is a bona fide resident and domiciliary of, not a temporary transient resident of, and has his principal residence in, the state or other jurisdiction set forth under Optionee's signature in the Option Agreement, and Optionee does not have any present intention of moving his principal residence from such state or jurisdiction. 14. Withholding Taxes. Whenever Option Shares are to be issued under the ----------------- Option Agreement, the Company shall have the right to require Optionee to remit to the Company an amount sufficient to satisfy federal, state and local withholding tax requirements prior to issuance and/or delivery of any certificate or certificates for such Option Shares. 15. Financial Information. The Corporation shall provide to each Optionee --------------------- on an annual basis a copy of the annual financial report prepared by the Company's independent certified public accountants, or such other periodic financial report which conforms with Section 260.140.46 of Title 10 of the California Code of Regulations. 16. Miscellaneous. ------------- (a) The Option Agreement shall bind and inure to the benefit of the parties' heirs, legal representatives, successors and permitted assigns. (b) The Option Agreement, the Plan, and these Terms and Conditions constitute the entire agreement between the parties pertaining to the subject matter contained herein and they supersede all prior and contemporaneous agreements, representations and understandings of the parties. No supplement, modification or amendment of the Option Agreement shall be binding unless executed in writing by all of the parties. No waiver of any of the provisions of the Option Agreement shall be deemed or shall constitute a waiver of any other provisions, whether or not similar, nor shall any waiver constitute a continuing waiver.

A copy of the Plan has been delivered to the Optionee and also may be inspected by Optionee at the principal office of the Company.

Attachment I STOCK OPTION AGREEMENT

EXHIBIT 10.4 Wireless Facilities, Inc. 1999 Equity Incentive Plan Stock Option Agreement (Incentive and Nonstatutory Stock Options) Pursuant to your Stock Option Grant Notice ("Grant Notice") and this Stock Option Agreement, Wireless Facilities, Inc. (the "Company") has granted to you an option under its 1999 Wireless Facilities, Inc. Equity Incentive Plan (the "Plan") to purchase the number of shares of the Company's Common Stock indicated in your Grant Notice at the exercise price indicated in your Grant Notice. Defined terms not explicitly defined in this Stock Option Agreement but defined in the Plan shall have the same definitions as in the Plan. The details of your option are as follows: 1. Vesting. Subject to the limitations contained herein, your option will vest as provided in your Grant Notice, provided that vesting will cease upon the termination of your Continuous Service. 2. Number of Shares and Exercise Price. The number of shares of Common Stock subject to your option and your exercise price per share referenced in your Grant Notice may be adjusted from time to time for capitalization adjustments, as provided in Section 11(a) of the Plan. 3. Exercise prior to Vesting ("Early Exercise"). If permitted in your Grant Notice (i.e., the "Exercise Schedule" indicates that "Early Exercise" of your option is permitted) and subject to the provisions of your option, you may elect at any time that is both (i) during the period of your Continuous Service and (ii) during the term of your option, to exercise all or part of your option, including the nonvested portion of your option; provided, however, that: (a) a partial exercise of your option shall be deemed to cover first vested shares of Common Stock and then the earliest vesting installment(s) of unvested shares of Common Stock; (b) any shares of Common Stock so purchased from installments that have not vested as of the date of exercise shall be subject to the purchase option in favor of the Company as described in the Company's form of Early Exercise Stock Purchase Agreement; (c) you shall enter into the Company's form of Early Exercise Stock Purchase Agreement with a vesting schedule that will result in the same vesting as if no early exercise had occurred; and (d) if your option is an incentive stock option, then, as provided in the Plan, to the extent that the aggregate Fair Market Value (determined at the time of grant) of the shares of Common Stock with respect to which your option plus all other incentive stock options you hold

are exercisable for the first time by you during any calendar year (under all plans of the Company and its Affiliates) exceeds one hundred thousand dollars ($100,000), your option(s) or portions thereof that exceed such limit (according to the order in which they were granted) shall be treated as nonstatutory stock options. 4. Method of Payment. Payment of the exercise price is due in full upon exercise of all or any part of your option. You may elect to make payment of the exercise price in cash or by check or in any other manner permitted by your Grant Notice, which may include one or more of the following: (a) In the Company's sole discretion at the time your option is exercised and provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board that, prior to the issuance of Common Stock, results in either the receipt of cash (or check) by the Company or the receipt of irrevocable instructions to pay the aggregate exercise price to the Company from the sales proceeds. (b) Provided that at the time of exercise the Common Stock is publicly traded and quoted regularly in The Wall Street Journal, by delivery of already-owned shares of Common Stock either that you have held for the period required to avoid a charge to the Company's reported earnings (generally six months) or that you did not acquire, directly or indirectly from the Company, that are owned free and clear of any liens, claims, encumbrances or security interests, and that are valued at Fair Market Value on the date of exercise. "Delivery" for these purposes, in the sole discretion of the Company at the time you exercise your option, shall include delivery to the Company of your attestation of ownership of such shares of Common Stock in a form approved by the Company. Notwithstanding the foregoing, you may not exercise your option by tender to the Company of Common Stock to the extent such tender would violate the provisions of any law, regulation or agreement restricting the redemption of the Company's stock. (c) Pursuant to the following deferred payment alternative: (i) Not less than one hundred percent (100%) of the aggregate exercise price, plus accrued interest, shall be due four (4) years from date of exercise or, at the Company's election, upon termination of your Continuous Service. (ii) Interest shall be compounded at least annually and shall be charged at the minimum rate of interest necessary to avoid the treatment as interest, under any applicable provisions of the Code and as reasonably determined by the Company, of any portion of any amounts other than amounts stated to be interest under the deferred payment arrangement. (iii) At any time that the Company is incorporated in Delaware, payment of the Common Stock's "par value," as defined in the Delaware General Corporation Law, shall be made in cash and not by deferred payment. 2

(iv) In order to elect the deferred payment alternative, you must, as a part of your written notice of exercise, give notice of the election of this payment alternative and, in order to secure the payment of the deferred exercise price to the Company hereunder, if the Company so requests, you must tender to the Company a promissory note and a security agreement covering the purchased shares of Common Stock, both in form and substance satisfactory to the Company, or such other or additional documentation as the Company may request. 5. Whole Shares; Minimum Purchase. You may exercise your option only for whole shares of Common Stock.. Unless you exercise your option with respect to all shares then vested, or unless otherwise permitted by the Company, you may exercise your option only for at least [one hundred (100)] shares on any exercise date. 6. Securities Law Compliance. Notwithstanding anything to the contrary contained herein, you may not exercise your option unless the shares of Common Stock issuable upon such exercise are then registered under the Securities Act or, if such shares of Common Stock are not then so registered, the Company has determined that such exercise and issuance would be exempt from the registration requirements of the Securities Act. The exercise of your option must also comply with other applicable laws and regulations governing your option, and you may not exercise your option if the Company determines that such exercise would not be in material compliance with such laws and regulations. 7. Term. The term of your option commences on the Date of Grant and expires upon the earliest of the following: (a) in the sole discretion of the Board, immediately upon the termination of your Continuous Service for Cause; (b) thirty (30) days after the termination of your Continuous Service for any reason other than Cause, Disability or death, provided that if during any part of such thirty (30) day period you may not exercise your option solely because of the condition set forth in the preceding paragraph relating to "Securities Law Compliance," your option shall not expire until the earlier of the Expiration Date or until it shall have been exercisable for an aggregate period of thirty (30) days after the termination of your Continuous Service; (c) twelve (12) months after the termination of your Continuous Service due to your Disability; (d) eighteen (18) months after your death if you die either during your Continuous Service or within thirty (30) days after your Continuous Service terminates for reason other than Cause; (e) the Expiration Date indicated in your Grant Notice; or (f) the day immediately preceding the tenth (10th) anniversary of the Date of Grant. 3

For purposes of your option, "Cause" means that the Board determines in good faith that you have engaged in misconduct, including but not limited to: (i) your commission of any felony or any crime involving moral turpitude or dishonesty, (ii) your participation in a fraud or act of dishonesty against or adversely affecting the Company, or (iii) your intentional, material violation of any contract between the Company and you, any statutory duty of yours to the Company or any policy of the Company which you do not correct within thirty (30) days after written notice to you thereof. Your physical or mental disability shall not constitute "Cause." If your option is an incentive stock option, note that, to obtain the federal income tax advantages associated with an "incentive stock option," the Code requires that at all times beginning on the date of grant of your option and ending on the date three (3) months before the date of your option's exercise, you must be an employee of the Company or an Affiliate, except in the event of your death or Disability. The Company has provided for extended exercisability of your option under certain circumstances for your benefit but cannot guarantee that your option will necessarily be treated as an "incentive stock option" if you continue to provide services to the Company or an Affiliate as a Consultant or Director after your employment terminates or if you otherwise exercise your option more than three (3) months after the date your employment terminates. 8. Exercise. (a) You may exercise the vested portion of your option (and the unvested portion of your option if your Grant Notice so permits) during its term by delivering a Notice of Exercise (in a form designated by the Company) together with the exercise price to the Secretary of the Company, or to such other person as the Company may designate, during regular business hours, together with such additional documents as the Company may then require. However, your option shall not be exercisable at any time that the Company is investigating whether it has grounds to terminate your Continuous Service for Cause. (b) By exercising your option you agree that, as a condition to any exercise of your option, the Company may require you to enter into an arrangement providing for the payment by you to the Company of any tax withholding obligation of the Company arising by reason of (1) the exercise of your option, (2) the lapse of any substantial risk of forfeiture to which the shares of Common Stock are subject at the time of exercise, or (3) the disposition of shares of Common Stock acquired upon such exercise. (c) If your option is an incentive stock option, by exercising your option you agree that you will notify the Company in writing within fifteen (15) days after the date of any disposition of any of the shares of the Common Stock issued upon exercise of your option that occurs within two (2) years after the date of your option grant or within one (1) year after such shares of Common Stock are transferred upon exercise of your option. 9. Transferability. Your option is not transferable, except by will or by the laws of descent and distribution, and is exercisable during your life only by you. Notwithstanding the foregoing, by delivering written notice to the Company, in a form satisfactory to the Company, 4

you may designate a third party who, in the event of your death, shall thereafter be entitled to exercise your option. 10. Right of Repurchase. To the extent provided in the Company's bylaws as amended from time to time, the Company shall have the right to repurchase all or any part of the shares of Common Stock you acquire pursuant to the exercise of your option. 11. Option not a Service Contract. Your option is not an employment or service contract, and nothing in your option shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ of the Company or an Affiliate, or any obligation of the Company or an Affiliate to continue your employment. In addition, nothing in your option shall obligate the Company or an Affiliate, their respective shareholders, Boards of Directors, Officers or Employees to continue any relationship that you might have as a Director or Consultant for the Company or an Affiliate. 12. Withholding Obligations. (a) At the time you exercise your option, in whole or in part, or at any time thereafter as requested by the Company, you hereby authorize withholding from payroll and any other amounts payable to you, and otherwise agree to make adequate provision for (including by means of a "cashless exercise" pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Board to the extent permitted by the Company), any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or an Affiliate, if any, which arise in connection with your option. (b) Upon your request and subject to approval by the Company, in its sole discretion, and compliance with any applicable conditions or restrictions of law, the Company may withhold from fully vested shares of Common Stock otherwise issuable to you upon the exercise of your option a number of whole shares of Common Stock having a Fair Market Value, determined by the Company as of the date of exercise, not in excess of the minimum amount of tax required to be withheld by law. If the date of determination of any tax withholding obligation is deferred to a date later than the date of exercise of your option, share withholding pursuant to the preceding sentence shall not be permitted unless you make a proper and timely election under Section 83(b) of the Code, covering the aggregate number of shares of Common Stock acquired upon such exercise with respect to which such determination is otherwise deferred, to accelerate the determination of such tax withholding obligation to the date of exercise of your option. Notwithstanding the filing of such election, shares of Common Stock shall be withheld solely from fully vested shares of Common Stock determined as of the date of exercise of your option that are otherwise issuable to you upon such exercise. Any adverse consequences to you arising in connection with such share withholding procedure shall be your sole responsibility.

WFI, Inc. SALES AGREEMENT FOR PRODUCTS & SERVICES - -------------------------------------------------------------------------------- Attachment 1 PROJECT PLAN WEB ENTERPRISE DEVELOPMENT PLAN 1. INTRODUCTION Project Overview This document will describe the conversion of the Integrated Venture's Project Tracker and Cost Tracker software, to an Internet-based, multi-tiered enterprise system running on the World Wide Web and using an SQL database as the data store. Although the current Tracker has been used successfully in several cellular/PCS build-out's, the move to an enterprise-wide system using the Internet for communications is the next logical step. The Tracker has recently undergone an extensive re-engineering effort to productize the application. Productizing means that the program logic and database have been separated from the specific terminology and field values that are specific to each project. Simply put, this means a single code base can be used to satisfy many clients with no programming changes. Each new client tailors the system to the way they use it and no custom programming is required. This added flexibility was a necessary step before the conversion to the Web version and will simplify the process. The current database design, with some minor changes, will be directly portable to a more robust SQL database. The complex modules, such as the Scheduling Engine, have been carved out so they will be portable to objects running on the server. In short, the effort to re- engineer Project Tracker for the Web will require no fundamental conceptual redesign, only a porting to the unique environment of the Web, a task that is extensive already. 1.2 Assumptions This document assumes that the initial port to Web technology will add no new functionality or feature to the system, other than those inherently required by this change. Although it is tempting to add many new features (some of which will be discussed later), it is recommended that the initial port keep the same feature set to minimize budgetary risks. It must also be kept in mind that this reengineering will require a significant detail design phase in which some of the proposed methods or timeframes may change. Like many complex processes, software development projects contain many tradeoff's that must be ultimately be decided by the customer. A detail design will help identify those tradeoff's up-front and not allow them to appear during the costly construction phase. A good design will help ensure the end product meets the business goals and needs of the customer, not those of the developers. 1.3 System Background Project Tracker is designed to manage the process of building a cellular and PCS telecommunication network. The defining attribute of this process is the large number of sub-projects, potential and final building site in this case, that have very similar tasks. Some of the features include: . Providing a data repository for search rings, candidate sites, and schedule . Providing a common framework measuring project progress and success . Act as a user-friendly front end to the scheduling engine of Microsoft Project . Managing all current tasks and projecting future task completion - -------------------------------------------------------------------------------- Integrated Ventures, LLC. - Confidential Page 7 04/20/99

WFI, Inc. SALES AGREEMENT FOR PRODUCTS & SERVICES - -------------------------------------------------------------------------------- . Site level budgeting and cost analysis . Electronic vendor invoice acceptance tied to cost structure and budgets . High level corporate reporting . Easy to use, sophisticated detail reporting . Complete user control on setup, lookup tables, and tasks The current Tracker application is written in Microsoft Access 97 and uses the Microsoft JET Database Engine. The JET Engine is the native database to Access and is in the `desktop' database class. In addition, a third party program, Flipper Graphs, is used to create the charts and graphs. Tracker is designed to run over a Local Area Network at each branch office and contains an export function to move the data to a corporate site. The corporate version imports the data from branch offices and can view data within or across the markets. While this design works well on a LAN, moving it to a Wide Area Network would cause excessive overhead and slow the application down dramatically. 1.4 General Benefits of Using the Web Moving any application to the Web can have many benefits: 1. All data is centrally stored and managed by the Vendor. 2. New clients can be put online immediately. No cumbersome software installation process is required at the client sites. This will be particularly import for international clients. 3. The sales process is simplified by not requiring the client to install and support expensive database hardware and software. Web software can be viewed by any platform having a compatible browser. 4. The vendor realizes economies of scale in the hardware and software investment by running many clients on a single system. 5. Technical support is greatly simplified as all data and programs for all clients reside in a single location. 6. Users are able to easily access information from any location all that is required is an Internet connection and browser. 7. Upgrades are streamlined as all changes are done in-house and can be slip streamed into production systems with a minimum of interruption. 1.5 Specific Benefits of Having Project Tracker on the Web 1. Telecom projects tend to be geographically dispersed with branch offices separate from the corporate office. Centralizing the data allows for each office to manage their own data and schedules while providing real-time roll-up and system-wide information for the corporate office. 2. Telecom projects tend to be transient in nature and an investment in expensive server equipment and database software could be a barrier to sales. Providing immediate `plug and play' functionality removes a significant barrier to sales. 3. Batching large numbers of schedules can be resource intensive and tie up users machines in a local are network. A Web design would centralize those functions at the server and allow for unattended batching at predetermined intervals. - -------------------------------------------------------------------------------- Integrated Ventures, LLC. - Confidential Page 8 04/20/99

WFI, Inc. SALES AGREEMENT FOR PRODUCTS & SERVICES - -------------------------------------------------------------------------------- 4. Electronic invoicing is a natural fit for the Web. Vendors can enter site specific charges directly to the Web without having to use a complex import/export routine. 5. Corporate data will be real-time. Instead of an import at regular intervals, corporate user's can view the live data and make decisions with up-to-the-minute information. 2 PROJECT ORGANIZATION 2.1 Staffing Model Developing web-based software requires software engineers with a variety of backgrounds and skills. Developing software for the Web is inherently different than standard Windows software in several respects. First, the component parts of the system, user interface, database, and program business logic are distinct disciplines often requiring different staff members. Some staff members are not required for the entire project but may participate for a percentage of the time. User Interface - -------------- HTML programmers familiar with the intricacies and challenges of a web application create the user interface. User interface programming tools are much more limited, thus more difficult to program, than standard Windows software. Often, this person contributes to the overall look, feel, and flow of the system. In addition, the Web is a very graphic medium and typically requires someone familiar with a graphics program, such as Adobe Photoshop. It may also require the services graphic artist to design icons and logo's. Database - -------- Because the database is a separate layer from the program logic, a specialist in database creation and programming is required. Data access routines are moved to the database to ensure optimal performance. The database programmer works closely with the business logic programmer. Program Logic - ------------- A programmer is required to create the business objects that act as glue between the user interface and the database. The business objects include data entry validation routines, Active Server Scripting routines, and specialty modules like the Project Scheduling module. This layer is critical in a Web application because the user interface, created in HTML, can only contain the most rudimentary logic. Project Manager - --------------- Even more so than standard software, a Project Manager is required to oversee the process of tying the layers outlines above together. A good application starts with a strong design and incorporates the objectives and business practices of the organization. The design is then translated into a working program with the oversight of the Project Manager. The Project Manager also acts as the go-between for the programming staff and the customer. Web Master - ---------- A Web Master will be required for a small amount of time to manage the directories and security required for a Web application. Project Tracker for the Web will require password protection and all users must have explicit access via an Access Control List (ACL) managed at the Web server location. 2.2 General Task Plan The steps required for creation of the Web version are as follows: - -------------------------------------------------------------------------------- Integrated Ventures, LLC. - Confidential Page 9 04/20/99

WFI, Inc. SALES AGREEMENT FOR PRODUCTS & SERVICES - -------------------------------------------------------------------------------- Detail Design - ------------- Participants: Customer, Project Manager, Lead Programmer Deliverable: Requirements Analysis and Detail Design Document Percentage Time of Overall Project: 20% This step involves meeting with the customer to determine general goals and requirements specific to the organization. Design and programming decisions involve trade-off between many factors. This initial design overview will help guide many of these decisions. After these initial meetings, there will be enough information for a basic requirement document to be created. This will outline the general strategy and a crude resource requirement & timeline analysis. After presenting and refining the requirements document, the project manager and lead programmer will create a detail design document outlining the system flows, screens, tables and routines in a concrete fashion. Many screens will be prototyped so the customer can provide feedback on look and feel. The Design Document will go through several iterations and refinements and will ultimately result in a much finer resource and timeline analysis. If successful, the Design document will provide a concrete look at what the final product will look like. Construction Phase - ------------------ Participants: Project Manager, All Programmers Deliverable: Alpha Release Percentage Time of Overall Project: 45% This phase is the actual programming involved in bring the product to life. The Detailed Design document will guide the daily tasks and the Project Manager will track progress against the initial schedule. Any schedule deviations will be reported to the customer immediately and the schedule readjusted to reflect the delay. During this phase, it is important for the Project Manager to meet with the customer on a regular basis to display progress and receive feedback. Often during this phase, the client proposes changes and additions to project and it is the Project Manager's job to analyze the request and communicate the impact on the schedule. During the construction phase, the Project Manager designs a test plan for each module and does unit testing according to the plan. Modules will be tested and not considered complete until no Type 1 (critical, apparent) bugs can be found. Unit Integration and Testing - ---------------------------- Participants: Customer, Project Manager, All Programmers Deliverable: Beta Release Percentage Time of Overall Project: 10% - -------------------------------------------------------------------------------- Integrated Ventures, LLC. - Confidential Page 10 04/20/99

WFI, Inc. SALES AGREEMENT FOR PRODUCTS & SERVICES - -------------------------------------------------------------------------------- During this phase, individual modules are combined to create a working system. The customer participates in the testing at this point to provide feedback about system performance how meeting of expectations. During this phase, the Project Manager creates the comprehensive test plan and runs multiple iterations until no Type 1 bugs can be found. Beta Testing - ------------ Participants: Customer, Client, Project Manager, All Programmers Deliverable: Version 1.0 Percentage Time of Overall Project: 20% This important phase involves rolling the product out to a customer willing to use the system and provide valuable feedback about performance and results. This phase takes the application out of the laboratory and into the real world, where the development staff can receive direct feedback about how the product is used in the field. It is critical to line up a willing Beta client in advance that will spend the necessary time to test and provide feedback. The goal of this phase is to reconfigure any cumbersome or incorrectly designed modules, and remove any Type 2 (apparent) and Type 3 (multiple interaction) bugs. Project Post Mortem - ------------------- Participants: Customer, Project Manager Deliverable: Final Documents Percentage Time of Overall Project: 5% 2.3 Specific Tasks and Issues Moving Project Tracker to the Web will necessitate changing how the overall application works. Below is a list of known changes that will be required. . Database Upsizing The current Access database must be moved to an SQL Enterprise database. This task is made easier by the fact that the current database design is about 90% sufficient for the conversion already. The final 10% has to do with adding keys and indexes to allow for multiple clients sharing a single database and segmenting all data retrieval to only return client specific information. A Microsoft tool to upsize the current structures to Oracle or SQL Server simplifies the physical task of moving the database structures to an SQL database. . Data Retrieval Routines Must data retrieval routines will be converted from Access/VB code and Access views to SQL Views and Stored Procedures. This will increase data throughput and allow for a clean separation between client (browser in this case) and database server. Separating client and server allows for maximum flexibility in future development. In addition, many if these data requests will be moved a Web Server data middle ware package like Active Server Pages or an equivalent. - -------------------------------------------------------------------------------- Integrated Ventures, LLC. - Confidential Page 11 04/20/99

WFI, Inc. SALES AGREEMENT FOR PRODUCTS & SERVICES - -------------------------------------------------------------------------------- . Individual Screen Design Each screen must be redesigned and re-coded to fit the Web/browser model of database access. HTML, the language of Web user interface development, is somewhat rudimentary compared to the Windows environment. While this simplicity has proven a strength for speed and cross platform compatibility, it poses specific challenges for developers. Many data access and entry tools are not available in a pure HTML environment. For example the data grid, a spreadsheet like representation of multiple rows of data, can only be approximated in a pure HTML environment. These issues will be identified and dealt with in the design phase of the project. . Data Validation Routines These routines are embedded in the current Access code to ensure data integrity. In a Web environment, these routines will be re-coded as objects and run on the Web Server as server side validation routines. This is part of the middle tier in a Web environment. . Module Routines Similar to data validation, complex modules, such as Project Scheduling, will be moved out of the front end and into the middle tier and run as server side objects. . Corporate Reporting Conversion The corporate reports will be redesigned to run as a server side object. HTML report access screens must be created for executives to request the reports, then server objects will create the graphs and drill-down hot zones for the returned Web page. - -------------------------------------------------------------------------------- Integrated Ventures, LLC. - Confidential Page 12 04/20/99
