     ----------------------------
establish branch or subordinate offices at any place or places where the
corporation is qualified to do business.


                                  ARTICLE II.


                            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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

     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.  The Board of
Directors may keep the books of the corporation outside the State of Delaware.

     Section 5.  -  Quorum; Vote Required for Action.  A majority of the
     -----------------------------------------------
authorized number of directors shall constitute a quorum for the transaction of
business, except to adjourn as provided in Section 7 of this Article III.  Every
act or decision done or made by a majority of the directors present at a meeting
duly held at which a quorum is present shall be regarded as the act of the Board
of Directors, except as may be otherwise specifically provided by statute, the
Certificate of Incorporation or these Bylaws.

                                       5
<PAGE>

     Section 6.  -  Action Without Meeting.  Any action required or permitted to
     -------------------------------------
be taken by the Board of Directors may be taken without a meeting, if all
members of the Board shall individually or collectively consent in writing to
that action.  Such action by written consent shall have the same force and
effect as a unanimous vote of the Board of Directors.  Such written consent or
consents shall be filed with the minutes of the proceedings of the Board.

     Section 7.  -  Adjournment; Notice.  If a quorum shall not be present at
     ----------------------------------
any meeting of the Board of Directors the directors present thereat may adjourn
the meeting from time to time.  Notice of the time and place of holding an
adjourned meeting need not be given, unless the meeting is adjourned for more
than 24 hours, in which case notice of the time and place shall be given at
least 24 hours before the time of the adjourned meeting to the directors who
were not present at the time of the adjournment.

     Section 8.  -  Fees and Compensation of Directors.  Directors and members
     -------------------------------------------------
of committees may receive such compensation, if any, for their services, and
such reimbursement of expenses, as may be fixed or determined by resolution of
the Board of Directors.  No such payment shall preclude any director from
serving the corporation in any other capacity and receiving compensation
therefor.

     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
<PAGE>

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
<PAGE>

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.

stockholders by written consent 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 and which record date shall not be
more than 60 days before any such action.  If no record date is fixed, the
record date for determining stockholders for any such purpose shall be at the

Financial Officer or an Assistant Treasurer or the Secretary or any Assistant
Secretary, certifying the number of shares and the class or series of shares

has signed or whose facsimile signature has been placed on a certificate shall
have ceased to be that officer, transfer agent or registrar before that
certificate is issued, it may be issued by the corporation with the same effect

class of stock or more than one series of any class, the powers, designations,
preferences and relative, participating, optional or other special rights of
each class of stock or series thereof and the qualification, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate which the corporation shall
issue to represent such class or series of stock, provided that, except as
otherwise provided in Section 202 of the Delaware General Corporation Law, in

of the certificate which the corporation shall issue to represent such class or
series of stock, a statement that the corporation will furnish without charge to
each stockholder who so requests the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualifications, limitations or restrictions of such

     Section 4.  -  Lost Certificates.  Except as provided in this Section 4, no
     --------------------------------
new certificates for shares shall be issued to replace an old certificate unless
the latter is surrendered to the corporation and cancelled at the same time.
The Board of Directors may, in case any share certificate or certificate for any
other security is lost, stolen or destroyed, authorize the issuance of a
replacement certificate on such terms and conditions as the Board may require,
including provision for indemnification of the corporation secured by a bond or
other adequate security sufficient to protect the corporation against any claim
that may be made against it, including any expense or liability on account of
the alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

     Section 5.  -  Construction and Definitions.  Unless the context requires

     ---------------------------------
or the transfer agent of the corporation, of a certificate for shares duly

certificates to the persons entitled thereto, cancel the old certificates and
record the transaction upon its books.

     Section 7.  -  Registered Stockholders.  The corporation shall be entitled
     --------------------------------------
to treat the holder of record of any share or shares of stock as the holder in
fact thereof and accordingly shall not be bound to recognize any equitable or
other claim or interest in such share on the part of any other person, whether
or not it shall have express or other notice thereof, save as expressly provided
by the laws of the State of Delaware.

     Section 8.  -  Dividends.
     ------------------------

          (a) Dividends upon the capital stock of the corporation, subject to
the provisions of the Certificate of Incorporation, in any, may be declared by

          (b) Before payment of any dividend the directors may set aside out of
any funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve fund to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purpose as the directors shall think conducive to the interests of the
corporation, and the directors may abolish such reserve.

     Section 10.  -  Notices.
     -----------------------

          (a) Whenever, under the provisions of the statutes or of the
Certificate of Incorporation or of these Bylaws, notice is required to be given
to any director or stockholder, it shall not be construed to mean personal
notice, but such notice may be given in writing, by mail, addressed to such
director or stockholder, at his address as it appears on the records of the
Corporation, with postage prepaid, and such notice shall be deemed to be given
at the time when the same shall be deposited in the United States mail.  Notice
to directors may also be given by telephone or telegram.

          (b) Whenever any notice is required to be given under the provisions
of the statutes or of the Certificate of Incorporation or of these Bylaws, a
waiver thereof in writing, signed by the person or persons entitled to said
notice, whether before or after the time stated therein, shall be deemed to be
equivalent.  Attendance of a person at a meeting shall constitute a waiver of
notice of such meeting, except when the person attends a meeting for the express
purpose of objecting at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.

     Section 11.  -  Annual Statement.  The Board of Directors shall present at

for by vote of the stockholders, a full and clear statement of the business and
condition of the corporation.

     --------------------------
treated for federal or state tax purposes as an S Corporation, unless such S
election has been revoked by the affirmative action of the majority of the
shares entitled to vote on such action, the corporation will not, nor be
compelled to recognize, for so long as the Corporation's status as an S
Corporation continues, any transfer to whom or to which in the opinion of
counsel to the corporation could disqualify the corporation as an S Corporation.


                                 ARTICLE VIII.


                             RIGHT OF FIRST REFUSAL

     Section 1.  -  Right of First Refusal.  No stockholder shall sell, assign,
     -------------------------------------
pledge, or in any manner transfer any of the shares of stock of the corporation
or any right or interest therein, whether voluntarily or by operation of law, or
by gift or otherwise, except by a transfer which meets the requirements
hereinafter set forth in this bylaw:

          (a) If the stockholder desires to sell or otherwise transfer any of
his shares of stock, then the stockholder shall first give written notice
thereof to the corporation.  The notice shall name the proposed transferee and
state the number of shares to be transferred, the proposed consideration, and
all other terms and conditions of the proposed transfer.

          (b) For thirty (30) days following receipt of such notice, the
corporation shall have the option to purchase all (but not less than all) of the
shares specified in the notice at the price and upon the terms set forth in such
notice; provided, however, that, with the consent of the stockholder, the
corporation shall have the option to purchase a lesser portion of the shares
specified in said notice at the price and upon the terms set forth therein.  In
the event of a gift, property settlement or other transfer in which the proposed
transferee is not paying the full price

                                       14
<PAGE>

for the shares, and that is not otherwise exempted from the provisions of this
Section 1, the price shall be determined in accordance with the Delaware General
Corporation Law. In the event the corporation elects to purchase all of the
shares or, with consent of the stockholder, a lesser portion of the shares, it
shall give written notice to the transferring stockholder of its election and
settlement for said shares shall be made as provided below in paragraph (d).

          (c) The corporation may assign its rights hereunder.

          (d) In the event the corporation and/or its assignee(s) elect to
acquire any of the shares of the transferring stockholder as specified in said
transferring stockholder notice, the Secretary of the corporation shall so
notify the transferring stockholder and settlement thereof shall be made in cash
within thirty (30) days after the Secretary of the corporation receives said
transferring stockholder's notice; provided that if the terms of payment set
forth in said transferring stockholder's notice were other than cash against
delivery, the corporation and/or its assignee(s) shall pay for said shares on
the same terms and conditions set forth in said transferring stockholder's
notice.

          (e) In the event the corporation and/or its assignee(s) do not elect
to acquire all of the shares specified in the transferring stockholder's
notice, said transferring stockholder may, within the sixty-day period following
the expiration of the option rights granted to the corporation and/or its
assignee(s) herein, transfer the shares specified in said transferring
stockholder's notice which were not acquired by the corporation and/or its
assignee(s) as specified in said transferring stockholder's notice.  All shares
so sold by said transferring stockholder shall continue to be subject to the
provisions of this bylaw in the same manner as before said transfer.

          (f) Anything to the contrary contained herein notwithstanding, the
following transactions shall be exempt from the provisions of this bylaw if
counsel for the corporation determines that any S-corporation election of the
corporation will not be disturbed:

               i)  A stockholder's transfer of any or all shares held either
during such stockholder's lifetime or on death by will or intestacy to such
stockholder's immediate family or to any custodian or trustee for the account of
such stockholder or such stockholder's immediate family. "Immediate family" as
used herein shall mean spouse, lineal descendant, father, mother, brother, or
sister of the stockholder making such transfer.

               ii)  A stockholder's bona fide pledge or mortgage of any shares
with a commercial lending institution, provided that any subsequent transfer of
said shares by said institution shall be conducted in the manner set forth in
this bylaw.

               iii)  A stockholder's transfer of any or all of such
stockholder's shares to the corporation or to any other stockholder of the
corporation.

               iv)  A stockholder's transfer of any or all of such stockholder's
shares to a person who, at the time of such transfer, is an officer or director
of the corporation.

               v)  A corporate stockholder's transfer of any or all of its
shares pursuant to and in accordance with the terms of any merger,
consolidation, reclassification of

                                       15
<PAGE>

shares or capital reorganization of the corporate stockholder, or pursuant to a
sale of all or substantially all of the stock or assets of a corporate
stockholder.

               vi)  A corporate stockholder's transfer of any or all of its
shares to any or all of its stockholders.

               vii)  A transfer by a stockholder that is a limited or general

     In any such case, the transferee, assignee, or other recipient shall
receive and hold such stock subject to the provisions of this bylaw, and there
shall be no further transfer of such stock except in accord with this bylaw.

          (g) The provisions of this bylaw may be waived with respect to any
transfer either by the corporation, upon duly authorized action of its 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 (excluding the votes
represented by those shares to be transferred by the transferring stockholder).
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.

          (h) Any sale or transfer, or purported sale or transfer, of securities
of the corporation shall be null and void unless the terms, conditions, and
provisions of this bylaw are strictly observed and followed.

          (i) The foregoing right of first refusal shall terminate on either of
the following dates, whichever shall first occur:

               i)  On December 4, 2004; or

               ii)  One hundred eighty days after the date securities of the
corporation are first offered to the public pursuant to a registration statement
filed with, and declared effective by, the United States Securities and Exchange
Commission under the Securities Act of 1933, as amended.

          (j) The certificates representing shares of stock of the corporation

                   STANDARD TERMS AND CONDITIONS RELATING TO

                                                   adopted as of January 7, 1999

     The following Standard Terms and Conditions Relating to Nonstatutory Stock
Options (the "Terms and Conditions") apply to the Nonstatutory Stock Options
granted under the 1997 Stock Option Plan of Wireless Facilities, Inc. (the
"Plan"), the applicable terms of which are hereby incorporated by reference and
made a part of these standard Terms and Conditions. In turn, these Terms and
Conditions are incorporated by reference into each such Option. Whenever
capitalized terms are used in these Terms and Conditions, they shall have the
meaning specified (i) in the Plan, (ii) in the Wireless Facilities, Inc.
Nonstatutory Stock Option Agreement Facing Page (the "Facing Page") into which
these Terms and Conditions are incorporated by reference, or (iii) below, unless
the context clearly indicates to the contrary. As used herein and in the Plan,
the "Option Agreement" shall mean the Nonstatutory Stock Option Agreement Facing
Page and these Terms and Conditions as incorporated therein. The masculine
pronoun shall include the feminine and neuter, and the singular the plural,
where the context so indicates.

     1.   Term of Option.  Subject to the maximum time limitations in Section
          --------------
6(a) of the Plan, the term of the Option shall be the period commencing on the
date of the Option Agreement and ending on the Expiration Date (as defined in
the Facing Page), unless terminated earlier as provided herein or in the Plan.

     2.   Exercise Price.  The exercise price of the Option granted hereby shall
          --------------
be not less than eighty-five percent (85%) of the Fair Market Value of the
Option Shares subject to the Option on the date the Option is granted; provided,
however, if the Optionee owns (or is deemed to own pursuant to Section 424(d) of
the Code) stock possessing more than ten percent (10%) of the total combined
voting power of all classes of stock of the Company (or any of its Affiliates),
the exercise price of the Option shall be not less than one hundred ten percent
(110%) of the Fair Market Value of the Option Shares on the date the Option is
granted.

     3.   Exercise of Option.
          ------------------

          (a)  The Facing Page shall set forth the rate at which the Option
Shares shall become subject to purchase by Optionee; provided, however, such
Option Shares shall become subject to purchase ("vest") at an annual rate which
is not less than twenty percent (20%) of the total Option Shares subject to the
Option over the five (5) year period commencing with the date of the grant of
the Option.

          (b)  Optionee shall exercise the Option to the extent exercisable, in
whole or in part, by sending written notice to the Company in the form attached
hereto as Exhibit A of his intention to purchase Option Shares hereunder,
          ---------
together with a check in the amount of the full purchase price of the Option
Shares to be purchased. Except as otherwise provided in the Plan,
<PAGE>

Optionee shall not exercise the Option at any one time with respect to less than
the minimum number of Option Shares as is set forth on the Facing Page.

          (c)  Optionee agrees to complete and execute any additional documents
which the Company reasonably requests that Optionee complete in order to comply
with applicable federal, state and local securities laws, rules and regulations.

          (d)  Subject to the Company's compliance with all applicable laws,
rules and regulations relating to the issuance of such Option Shares and
Optionee's compliance with all the terms and conditions of the Option Agreement,
these Terms and Conditions and the Plan, the Company shall promptly deliver the
Option Shares to the Optionee.

          (e)  Except as otherwise provided herein or in the Plan, the Option
may be exercised during the lifetime of the Optionee only by the Optionee.

     4.   Option Not Transferable.  The Option granted hereunder shall not be
          -----------------------
transferable in any manner other than upon the death of Optionee as provided in
the Plan. More particularly (but without limiting the foregoing), the Option may
not be assigned, transferred (except as expressly provided herein), pledged or
hypothecated in any way, shall not be assignable by operation of law and shall
not be subject to execution, attachment or similar process. Any attempted
assignment, transfer, pledge, hypothecation or other disposition of the Option
contrary to the provisions hereof, or the levy of any execution, attachment or
similar process upon the Option, shall be null and void and without effect.

     5.   Termination of Option.
          ---------------------

          (a)  To the extent not previously exercised, the Option shall
terminate on the Expiration Date; provided, however, that except as otherwise
provided in this Section 5 the Option may not be exercised more than thirty (30)
                           ----------------------------------------------------
days after the Termination of Employment or Consulting Relationship of Optionee
- -------------------------------------------------------------------------------
for any reason (other than for Cause, as defined in the Plan, or upon Optionee's
- --------------------------------------------------------------------------------
death or Disability).  Within such thirty (30) day period, Optionee may
- --------------------
exercise the Option only to the extent the same was exercisable on the date of
such termination and said right to exercise shall terminate at the end of such
period.

          (b)  In the event of the Termination of Employment or Consulting
Relationship of Optionee for Cause, as defined in the Plan, the Option shall
expire as of the date of the occurrence giving rise to such termination or upon
the Expiration Date, whichever is earlier, and Optionee shall have no rights
with respect to any unexercised portion of the Option.

          (c)  In the event of the Termination of Employment or Consulting
Relationship of Optionee as a result of Optionee's Disability, the Option shall
be exercisable for a period of six (6) months from the date of such termination,
but in no event later than the Expiration Date and only to the extent that the
Option was exercisable on the date of such termination.

                                       2.
<PAGE>

          (d)  In the event of the Termination of Employment or Consulting
Relationship of Optionee as a result of Optionee's death, the Option shall be
exercisable by the Optionee's estate (or by the person who acquires the right to
exercise the Option by will or by the laws of descent and distribution) for a
period of six (6) months from the date of such termination, but in no event
later than the Expiration Date and only to the extent that the Optionee was
entitled to exercise the Option on the date of death.

          (e) Notwithstanding anything herein to the contrary, no portion of any
Option which is not exercisable by the Optionee upon the Termination of
Employment or Consulting Relationship of such Optionee shall thereafter become
exercisable, regardless of the reason for such termination.

     6.   No Right to Continued Relationship. The Option does not confer upon
          ----------------------------------
Optionee any right to continue in his capacity as an Employee, Consultant or
Director of the Company, nor does it limit in any way the right of the Company
to terminate Optionee's relationship with the Company at any time, with or
without cause.

     7.   Right of Repurchase of Option Shares.
          -------------------------------------

          (a)  Notwithstanding any provision herein to the contrary, the Option
Shares issued pursuant to the Option shall be subject to a right, but not an
obligation, of repurchase by the Company (the "Right of Repurchase"), at the
price determined under subsection (b) below, if prior to the Expiration Date or
the termination of the Right of Repurchase as provided in Section 9(d) below a
Termination of Employment or Consulting Relationship occurs for any reason,
including as a result of Optionee's death or Disability. Option Shares issued by
the Company shall not be transferable by the Optionee during the period during
which the Right of Repurchase applies, and the Company may take such steps as it
deems necessary to ensure compliance with this restriction.

          (b)  The price per share at which the Company may exercise the Right
of Repurchase (the "Repurchase Price") shall be the fair market value of an
Option Share on the date of the Termination of Employment or Consulting
Relationship of Optionee, as determined in good faith by the Company's Board of
Directors (or an officer appointed by the Board of Directors for such purpose).

          (c)  The Company's Right of Repurchase shall terminate if not
exercised by written notice from the Company to the Optionee within ninety (90)
days of the Termination of Employment or Consulting Relationship. If the Company
exercises its Right of Repurchase, it shall give notice thereof to the Optionee
within such ninety (90) day period, and, upon receipt of such notice, the
Optionee shall immediately endorse and deliver to the Company the stock
certificate(s) representing the Option Shares being repurchased, and the Company
shall then promptly pay, pursuant to the provisions of Section 7(d) below, the
total Repurchase Price to the Optionee. If the Company exercises its Right of
Repurchase it shall exercise its right with respect to all (not some) of such
Option Shares.

                                       3.
<PAGE>

          (d)  The Repurchase Price shall be paid first by cancellation of any
obligation for accrued but unpaid interest outstanding under notes issued by the
Optionee upon purchase of the Option Shares (if any), next by cancellation of
principal outstanding under such notes (if any), and finally by payment in cash
of the balance due.

          (e)  In the event the Company does not elect to exercise its Right of
Repurchase within the ninety (90) day period, the Option Shares shall no longer
be subject to repurchase by the Company pursuant to this Section 7.

     8.   Right of First Refusal.  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 so purchase
the offered Option Shares, they shall complete the purchase of such shares
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 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.

                                       4.
<PAGE>

          (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-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.

                                       5.
<PAGE>

          (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 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.

                                       6.
<PAGE>

     12.  Acknowledgments of Optionee.  Optionee acknowledges and agrees that:
          ---------------------------

          (a)  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.

          (b)  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 A NONSTATUTORY STOCK OPTION AGREEMENT
          (AND THE STANDARD TERMS AND CONDITIONS RELATING TO NONSTATUTORY 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 OF
          THE PROVISIONS OF WHICH ARE INCORPORATED HEREIN.

     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.

                                       7.
<PAGE>

          (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(b) hereof will be placed on the certificate(s) evidencing
the Option Shares and, except as otherwise provided in Section 12(b), 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.

          (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
          ---------------------

         -------------------------------------------------------------

                                                   adopted as of January 7, 1999

made a part of these standard Terms and Conditions. In turn, these Terms and
Conditions are incorporated by reference into each such Option. Whenever
capitalized terms are used in these Terms and Conditions, they shall have the
meaning specified (i) in the Plan, (ii) in the Wireless Facilities, Inc.
Incentive Stock Option Agreement Facing Page (the "Facing Page") into which

Page and these Terms and Conditions as incorporated therein. The masculine
pronoun shall include the feminine and neuter, and the singular the plural,
where the context so indicates.

     1.   Term of Option.  Subject to the maximum time limitations in Section
          --------------
6(a) of the Plan, the term of the Option shall be the period commencing on the
date of the Option Agreement and ending on the Expiration Date (as defined in
the Facing Page), unless terminated earlier as provided herein or in the Plan;
provided however, if the Optionee owns (or is deemed to own pursuant to Section
424(d) of the Code) stock possessing more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company (or any of its
Affiliates), the Option shall expire not later than five (5) years after the
date of the Option Agreement.

     2.   Exercise Price.  The exercise price of the Option granted hereby shall
          --------------
be not less than one hundred percent (100%) of the Fair Market Value of the
Option Shares subject to the Option on the date the Option is granted; provided,
however, if the Optionee owns (or is deemed to own pursuant to Section 424(d) of
the Code) stock possessing more than ten percent (10%) of the total combined
voting power of all classes of stock of the Company (or any of its Affiliates),
the exercise price of the Option shall be not less than one hundred ten percent
(110%) of the Fair Market Value of the Option Shares on the date the Option is
granted.

     3.   Exercise of Option.
          ------------------

          (a)  The Facing Page shall set forth the rate at which the Option
Shares shall become subject to purchase by Optionee; provided, however, such
Option Shares shall become subject to purchase ("vest") at an annual rate which
is not less than twenty percent (20%) of the total Option Shares subject to the
Option over the five (5) year period commencing with the date of the grant of
the Option.

          (b)  Optionee shall exercise the Option to the extent exercisable, in
whole or in part, by sending written notice to the Company in the form attached
hereto as Exhibit A of his
          ---------
<PAGE>

intention to purchase Option Shares hereunder, together with a check in the
amount of the full purchase price of the Option Shares to be purchased. Except
as otherwise provided in the Plan, Optionee shall not exercise the Option at any
one time with respect to less than the minimum number of Option Shares as is set
forth on the Facing Page.

          (c)  Optionee agrees to complete and execute any additional documents
which the Company reasonably requests that Optionee complete in order to comply
with applicable federal, state and local securities laws, rules and regulations.

          (d)  Subject to the Company's compliance with all applicable laws,
rules and regulations relating to the issuance of such Option Shares and
Optionee's compliance with all the terms and conditions of the Option Agreement,
these Terms and Conditions and the Plan, the Company shall promptly deliver the
Option Shares to the Optionee.

          (e)  Except as otherwise provided herein or in the Plan, the Option
may be exercised during the lifetime of the Optionee only by the Optionee.

     4.   Option Not Transferable.  The Option granted hereunder shall not be
          -----------------------
transferable in any manner other than upon the death of Optionee as provided in
the Plan. More particularly (but without limiting the foregoing), the Option may
not be assigned, transferred (except as expressly provided herein), pledged or
hypothecated in any way, shall not be assignable by operation of law and shall
not be subject to execution, attachment or similar process. Any attempted
assignment, transfer, pledge, hypothecation or other disposition of the Option
contrary to the provisions hereof, or the levy of any execution, attachment or
similar process upon the Option, shall be null and void and without effect.

     5.   Termination of Option.
          ---------------------

          (a)  To the extent not previously exercised, the Option shall
terminate on the Expiration Date; provided, however, that except as otherwise
provided in this Section 5 the Option may not be exercised more than thirty (30)
                           ----------------------------------------------------
days after the Termination of Employment or Consulting Relationship of Optionee
- -------------------------------------------------------------------------------
for any reason (other than for Cause, as defined in the Plan, or upon Optionee's
- --------------------------------------------------------------------------------
death or Disability). Within such thirty (30) day period, Optionee may exercise
- -------------------
the Option only to the extent the same was exercisable on the date of such
termination and said right to exercise shall terminate at the end of such
period.

          (b)  In the event of the Termination of Employment or Consulting
Relationship of Optionee for Cause, as defined in the Plan, the Option shall
expire as of the date of the occurrence giving rise to such termination or upon
the Expiration Date, whichever is earlier, and Optionee shall have no rights
with respect to any unexercised portion of the Option.

          (c)  In the event of the Termination of Employment or Consulting
Relationship of Optionee as a result of Optionee's Disability, the Option shall
be exercisable for a period of six (6) months from the date of such termination,
but in no event later than the Expiration Date and only to the extent that the
Option was exercisable on the date of such termination.

                                      2.
<PAGE>

          (d)  In the event of the Termination of Employment or Consulting
Relationship of Optionee as a result of Optionee's death, the Option shall be
exercisable by the Optionee's estate (or by the person who acquires the right to
exercise the Option by will or by the laws of descent and distribution) for a
period of six (6) months from the date of such termination, but in no event
later than the Expiration Date and only to the extent that the Optionee was
entitled to exercise the Option on the date of death.

          (e)  Notwithstanding anything herein to the contrary, no portion of
any Option which is not exercisable by the Optionee upon the Termination of
Employment or Consulting Relationship of such Optionee shall thereafter become
exercisable, regardless of the reason for such termination.

     6.   No Right to Continued Employment.  The Option does not confer upon
          --------------------------------
Optionee any right to continue in the employ of the Company, nor does it limit
in any way the right of the Company to terminate Optionee's employment at any
time, with or without cause.

     7.   Right of Repurchase of Option Shares.

          (a)  Notwithstanding any provision herein to the contrary, the Option
Shares issued pursuant to the Option shall be subject to a right, but not an
obligation, of repurchase by the Company (the "Right of Repurchase"), at the
price determined under subsection (b) below, if prior to the Expiration Date or
the termination of the Right of Repurchase as provided in Section 9(d) below a
Termination of Employment or Consulting Relationship occurs for any reason,
including as a result of Optionee's death or Disability. Option Shares issued by
the Company shall not be transferable by the Optionee during the period during
which the Right of Repurchase applies, and the Company may take such steps as it
deems necessary to ensure compliance with this restriction.

          (b)  The price per share at which the Company may exercise the Right
of Repurchase (the "Repurchase Price") shall be the fair market value of an
Option Share on the date of the Termination of Employment or Consulting
Relationship of Optionee, as determined in good faith by the Company's Board of
Directors (or an officer appointed by the Board of Directors for such purpose).

          (c)  The Company's Right of Repurchase shall terminate if not
exercised by written notice from the Company to the Optionee within ninety (90)
days of the Termination of Employment or Consulting Relationship. If the Company
exercises its Right of Repurchase, it shall give notice thereof to the Optionee
within such ninety (90) day period, and, upon receipt of such notice, the
Optionee shall immediately endorse and deliver to the Company the stock
certificate(s) representing the Option Shares being repurchased, and the Company
shall then promptly pay, pursuant to the provisions of Section 7(d) below, the
total Repurchase Price to the Optionee. If the Company exercises its Right of
Repurchase it shall exercise its right with respect to all (not some) of such
Option Shares.

          (d)  The Repurchase Price shall be paid first by cancellation of any
obligation for accrued but unpaid interest outstanding under notes issued by the
Optionee upon purchase of the

                                      3.
<PAGE>

Option Shares (if any), next by cancellation of principal outstanding under such
notes (if any), and finally by payment in cash of the balance due.

          (e)  In the event the Company does not elect to exercise its Right of
Repurchase within the ninety (90) day period, the Option Shares shall no longer
be subject to repurchase by the Company pursuant to this Section 7.

     8.   Right of First Refusal.  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.
<PAGE>

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.
<PAGE>

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.
<PAGE>

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

     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.
<PAGE>

          (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.  No waiver shall be binding unless executed in writing by the
party making the waiver.  In the event there exists any conflict or discrepancy
between any of the terms in the Plan and the Option Agreement, the terms of the
Plan shall be controlling.  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.

          (c)  Should any portion of the Plan, the Option Agreement or these
Terms and Conditions be declared invalid and unenforceable, then such portion
shall be deemed to be severable from the Option Agreement and shall not affect
the remainder hereof.

          (d)  All notices to be sent hereunder shall be delivered in person or
sent by United States Mail, certified and postage prepaid, to Optionee at the
address set forth on the Facing Page of the Option Agreement or to the Company
at its principal place of business, Attention: President. Any change in the
address to which notices shall be sent under the Option Agreement to the
Optionee shall be made by the Optionee upon ten (10) days' written notice to the
Company.

          (e)  The Option Agreement shall be construed according to the internal
laws of the State of California without resort to California's conflict-of-laws
provisions. The Option Agreement is made and entered into in San Diego,
California. The sole venue for adjudicating any action arising from or relating
to the Option Agreement shall be in San Diego, California.

                                      9.

                                                                    EXHIBIT 10.4

                          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
<PAGE>

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
<PAGE>

                (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
<PAGE>

     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
<PAGE>

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.

          (c) You may not exercise your option unless the tax withholding
obligations of the Company and/or any Affiliate are satisfied.  Accordingly, you
may not be able to exercise your option when desired even though your option is
vested, and the Company shall have no

                                       5
<PAGE>

obligation to issue a certificate for such shares of Common Stock or release
such shares of Common Stock from any escrow provided for herein.

     13.  Notices.  Any notices provided for in your option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by mail by the Company to you, five (5) days after
deposit in the United States mail, postage prepaid, addressed to you at the last
address you provided to the Company.

     14.  Governing Plan Document.  Your option is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your option, and
is further subject to all interpretations, amendments, rules and regulations
which may from time to time be promulgated and adopted pursuant to the Plan.  In
the event of any conflict between the provisions of your option and those of the
Plan, the provisions of the Plan shall control.

12.  Confidentiality. In order to permit Entel to perform its obligations

     use all Confidential Information solely for the purpose of performing its
     obligations to Triton under this Agreement, and shall keep confidential and
     not disclose to any other person, other than employees or agents of Entel
     who agree to be bound by an equivalent undertaking, any Confidential
     Information. The foregoing restrictions shall not apply to any Confidential
     Information:

          i.   which is made public by Triton or which otherwise is or hereafter
               becomes part of the public domain through no wrongful act, fault,
               or negligence on the part of Entel;

          ii.  which Entel can reasonably demonstrate is already in Entel's
               possession and not subject to an existing agreement of
               confidentiality;

          iii. which is received from a third party without restriction and
               without breach of an agreement with Triton;

          iv.  which is independently developed by Entel as evidenced by its
               records; or

          v.   which Entel is required to disclose pursuant to a valid order of
               a court or other governmental body or any political subdivision
               hereof; provided, however, that, to the extent that it may
               lawfully do so, Entel shall first have given notice to Triton and
               given Triton a reasonable opportunity to interpose an objection
               or obtain a protective order requiring that the Confidential
               Information so disclosed be used only for the purposes for which
               the order was issued.

13.  Independent Contractor. Entel is and shall act as an independent contractor
     ----------------------

     exercise full control of and supervision over its employees. Entel's
     personnel performing Services are agents, employees or subcontractors of
     Entel and are not employees or agents of Triton. Entel will be solely
     liable for all matters relating to compensation, unemployment, disability
     insurance, social security, withholding and all other federal, state and
     local laws, rules and regulations governing such matters.

14.  Prohibition of Solicitation. During the term of this Agreement, neither
     ---------------------------
     party shall solicit nor accept for employment any employees of the other
     party without the express written consent of the other party.

     -------------
     performing its obligations hereunder that is due to circumstances beyond
     such Party's reasonable control, including, but not limited to, acts of
     God, civil unrest, riots, war, fire, floods, explosions and strikes or
     other concerted acts of labor, provided that such circumstances were not
     reasonably foreseeable by such Party and, by the exercise of commercial due
     diligence, could not have been prevented or overcome by such Party. Upon
     the occurrence of a force majeure condition, the Party whose performance is
     affected shall give written notice to the other Party describing the
     affected performance. The parties shall promptly confer, in good faith, to
     agree upon equitable, reasonable action to minimize the impact of the
     condition on both parties. The parties agree that the Party whose
     performance is affected shall use commercially reasonable efforts to
     minimize the delay caused by the force majeure condition and recommence the
     affected performance. In the event that the delay caused by the force
     majeure event lasts for a period of more than thirty (30) days, the parties
     shall negotiate an equitable modification to this Agreement with respect to
     the affected performance. If the parties are unable to agree upon an
     equitable modification within fifteen (15) days after such thirty (30) day
     period has expired, then either Party shall be entitled to serve thirty
     (30) days notice of termination on the other Party with respect to only the
     affected performance. If the force majeure event for such affected
     performance continues upon the expiration of such thirty (30) day notice
     period the portion of this Agreement relating to the affected performance
     shall automatically terminate. The remaining portion of this Agreement that
     does not involve the affected performance shall continue in full force and
     effect.

16.  Limitation of Liability. Entel's liability with respect to services
     -----------------------
     provided hereunder shall not exceed the amount paid to Entel under this
     Agreement.

     ----------------------
     the other Party shall not be deemed a waiver of any other default. No
     provision of this Agreement shall be deemed waived, amended or modified by
     either Party, unless such waiver, amendment or modification is in writing
     and signed by the authorized representative of the Party against whom such
     waiver, amendment or modification is to be enforced.

                           Between Triton and Entel

                              Scope of Services
                              -----------------
                                     for
                                     ---
              Spectrum Sharing and Microwave Relocation Services
              --------------------------------------------------

Entel, utilizing the Comsearch IQ Clear spectrum sharing tool, procured and
provided by Entel, will supply to Triton all labor, services, resources, and
consultation necessary to perform the spectrum sharing study and analysis, drive
test frequency selection, and prior coordination notices described below
("Spectrum Sharing Services"). Entel will also provide Triton with the Microwave
Relocation Services described below.

1.   Spectrum Sharing Study and Analysis

     Entel will perform spectrum-sharing studies, as required by Triton, for the
     selected frequency, in each assigned BTA. The studies will initially be
     based on the generic traffic cell based design, which will be modified
     subsequently to include RF design information provided by Triton. Entel
     will identify all paths that could be affected by Triton's proposed PCS
     systems, based on FCC guidelines on interference avoidance. Entel will
     perform multiple interference studies for each assigned frequency and BTA,
     as required, over the course of the design and buildout phases.

2.   Drive Test Frequency Selection

     On a continuous basis as frequencies are assigned, Entel will complete the
     spectrum sharing study and analysis and provide Triton with the required
     drive test frequencies for the assigned BTS locations (if a non-interfering
     frequency is available).

3.   Prior Coordination Notices

     Entel will prepare Prior Coordination Notices (PCN(s)), mail PCNs to
     incumbents and clearinghouses, and coordinate responses and objections to
     PCNs, as required. Typically one PCN mailing will be required for each BTA,
     unless considerable RF engineering design changes occur later in the pre-
     launch phase. As a result of RF design changes, additional PCN(s) will be
     performed as required.

4.   Microwave Relocation Services

     Phased Delivery of Services
     ---------------------------

     Entel shall provide Triton with microwave relocation services (the
     "Services") as described below. The Services shall be delivered to Triton
     in three phases:

     Phase I:       Market Relocation Analysis
     -------

     Phase II:      Negotiations and Final Contract Execution
     --------

     Phase III:     Relocation Program Management
     ---------

     Phase I - Market Relocation Analysis

     Entel will utilize the results of the spectrum sharing study and analysis
     and will perform the following steps as required to complete assessment of
     interfering paths/incumbents as identified in the spectrum sharing study
     and analysis.

     A.   Service Description
          -------------------

          1.   Review and Catalog Path Data. Review information from the
               ----------------------------
               spectrum sharing study and analysis on a per market and per
               incumbent basis for both co-channel and adjacent channel paths.
               Information such as number of links, equipment and modulation
               type, capacity, site names and locations for each path will be
               logged for use during negotiations and relocation
<PAGE>

               program management.

          3.   Path Prioritization. Entel will develop technical parameters for
               -------------------
               the interfering co and adjacent channel paths to establish
               negotiation and relocation strategies and path priorities.

          4.   Review of Incumbent Data. Entel will review incumbent system
               ------------------------
               data on a per link basis and compare the information against FCC
               database information to determine whether the incumbent is
               operating on a primary status with a current license.

          5.   Path Status Verification and Initial Incumbent Assessment. Entel
               ---------------------------------------------------------
               will contact each incumbent to confirm database information,
               verify path status, i.e. active, negotiated, or decommissioned.
               If the incumbent has not entered into an agreement with another
               PCS licensee, then Entel will assess the incumbent's willingness
               to negotiate, identify strategic information, and discuss
               preliminary relocation options.

          6.   Assessment of Previously Negotiated Paths. Entel will attempt to
               -----------------------------------------
               obtain the terms and status of each relocation agreement entered
               into between an incumbent and other PCS licensee(s). Entel will
               attempt to obtain a copy of the agreement, provided that it is
               not protected by a non-disclosure agreement. Entel will determine
               whether the dates agreed upon in the relocation agreement meet
               Triton's requirements.

          7.   Estimate Comparable Relocation Costs. Estimate relocation costs
               ------------------------------------
               on a per incumbent and per market basis for paths that are
               determined to be active or co-channel paths that have been
               negotiated and/or relocated. Information such as system type and
               architecture, number of links required to be relocated, tower
               heights and typical system usage will be used to develop the cost
               estimates.

          8.   Route Mapping. Develop route maps on a per incumbent and per
               -------------
               market basis delineating co-channel and adjacent channel active
               paths.

     B.   Deliverables
          ------------

          Entel will provide to Triton a written report containing the following

     A.   Service Description
          -------------------

          1.   Introductory Mailing. Entel will identify the proper technical
               --------------------
               and negotiation contact for each incumbent and send an
               introductory mailing packet containing general information on
               microwave relocation and specific information about Triton and
               its proposed course of action.

          2.   Negotiation Parameters. Entel will work with Triton to develop
               ----------------------
               negotiation parameters. These parameters should be established
               prior to the commencement of negotiations so that settlements may
               be negotiated expeditiously.

          3.   Development of Negotiation Strategies. Entel will work with
               -------------------------------------
               Triton to develop optimal negotiation strategies for each
               incumbent and market. These strategies will be based upon the
               size and location of each incumbent's network, considering
               whether the incumbent is present in multiple Triton markets,
               Triton's priorities and its willingness to provide various
               relocation alternatives.

          4.   Initiate Negotiations. Entel will negotiate with incumbent to
               ---------------------
               reach an agreement that conforms to Triton's relocation schedule

          5.   Additional Negotiation and Finalization of Agreement for
               --------------------------------------------------------
               Amended Relocation Dates. If a path has been negotiated by
               ------------------------
               another PCS licensee, but the relocation date(s) are unacceptable
               to Triton, then Entel will initiate negotiations with the
               incumbent, other PCS licensee(s) or both to alter the
               unacceptable relocation dates and bring them into conformity with
               Triton's relocation priorities.

          6.   Negotiation Strategy. Entel will re-assess negotiation
               --------------------
               parameters and strategies as required based on discussions with
               incumbents, additional information obtained from incumbent
               meeting, and any modifications to Triton's deployment schedule.

          7.   Contract Templates. Triton's inside counsel shall review and
               ------------------
               modify, as required, the contract templates that Entel provided
               to Triton. These pre-approved contract templates are essential
               for enabling Entel to conclude negotiations in an efficient and
               expedient manner.

          8.   Finalize Relocation Terms. Entel will provide the proposed
               -------------------------
               business terms to Triton for approval.

          9.   Finalize Relocation Agreement. Once Triton has approved the
               -----------------------------
               business terms, Entel shall work with Triton's counsel to
               facilitate the negotiation and execution of the final relocation
               agreement between Triton and the incumbent.

     B.   Deliverables
          ------------

          Entel will provide Triton with the following deliverables:

          1.   Signed offer letter;

                              DATE: April 19, 1999


Integrated Ventures, LLC.
8880 Rio San Diego Drive, Suite 800
San Diego, CA 92108

This Sales Agreement, effective 4/20/99, is between Integrated Ventures, LLC, a
California Corporation ("IV"), and WFI ("Client"). This order, in conjunction
with the general agreement named above, sets forth the terms and conditions for
the following work as described below

I.   Description of Product and Services:
     A.  Product:
               PRODUCT DESCRIPTION:
               -------------------

               The Integrated Venture's Project Tracking System is a software
               tool designed to help top level managers build wireless and other
               telecommunications networks easier and faster and to manage those
               networks on into the future. The Project Tracking System is made
               up of two (2) different components, the Project Tracker, and the
               Cost Management System. Each of the components can be integrated
               for data sharing or used independently.

               The Project Tracker provides:
               .  Project Management Tools
               .  Task Scheduling
               .  Core Site Data Storage
               .  Project Reporting

               This product offers the manager weekly reports that will help by
               tracking and monitoring all of the critical variables and
               milestones involved with the deployment of a network. The program
               allows a manager to monitor the deployment of multiple market
               areas. It allows you to generate, analyze and create reports with
               a minimum amount of work. The scheduling feature makes it easy to
               plan and manage projects by giving you the ability to forecast
               the start and finish dates of key milestones. It also provides
               the ability to report on the performance of specific vendors. By
               tracking the duration of specific tasks, you are able to identify
               those vendors that are not operating at optimum performance.

               The Cost Management System provides:
               .  Invoice Authorization
               .  Electronic Billing
               .  Invoice Tracking
               .  Budget Development and Tracking
               .  Cost Reporting

               This product provides a means for tracking project costs. It
               allows the user to authorize project costs based on the actual
               progress and milestone completion. It automates the billing
               process to reduce the amount of time required to manage the
               multiple invoices and data entry required to maintain an accurate
               record of project costs. It also allows for the Project Team to
               develop budgets based on company general ledger codes and track
               those budgets to actual expenditures.

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

 . 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.

- --------------------------------------------------------------------------------

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:

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%

- --------------------------------------------------------------------------------

<PAGE>

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.

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.

                SETTLEMENT AGREEMENT AND MUTUAL GENERAL RELEASE

     THIS SETTLEMENT AGREEMENT AND MUTUAL GENERAL RELEASE (this "Agreement") is
made and entered into effective as of June 30, 1999 (the "Effective Date") by
and between TOTAL OUTSOURCING, INC., a California corporation ("TOI"), and
WIRELESS FACILITIES, INC., a Delaware corporation ("WFI"), with regard to the
following facts:

                               R E C I T A L S:

     A.  TOI has provided services and financing to WFI for the leasing of
computer equipment, apartments, vehicles and other items when WFI had limited
resources.


     B.  Now that WFI has substantial resources, the parties believe that their
contractual relationship is no longer a necessity and they would like to
document that their relationship has ceased, as of the Effective Date.


                               A G R E E M E N T

     In consideration of the mutual releases mentioned herein, the parties
acknowledge and agree:


     1.  Obligations Under Agreements Canceled.  Except for the agreements and
         -------------------------------------
covenants expressly provided in this Agreement (the "Covenants"), all
obligations of the parties existing under any express or implied agreements
between TOI and WFI existing prior to the Effective Date are hereby canceled and
all amounts owing under them are hereby deemed paid in full.


     2.  TOI's Agreements and Covenants.  Each party hereby agrees and covenants
         ------------------------------
to return all property of the other upon request, including, but not limited to,
all office and building keys, equipment, supplies and files, all copies of same
and any data relating to same.  TOI agrees not to use or disclose any
information its personnel learned or learns about WFI or its officers,
directors, shareholders, agents or representatives.


     3.  WFI's Agreements And Covenants.  WFI hereby agrees to provide TOI a
         ------------------------------
check in the amount of Two Hundred Eighty Thousand Ninety-One Dollars ($280,091)
no later than December 31, 1999.


     4.  Mutual Release.  TOI hereby releases and discharges WFI and all of
         --------------
WFI's agents, representatives, officers, directors, shareholders, attorneys and
accountants, and WFI
<PAGE>

hereby releases and discharges TOI and all of TOI's agents, representatives,
officers, directors, shareholders, attorneys and accountants, from all debts,
claims, demands, liabilities, agreements and causes of action that the parties
ever had, now have, or may have, whether accrued or contingent, against each
other arising out of or relating to any and all agreements between them or their
relationship, except for the Covenants.


     5.  Compromise.  This Agreement constitutes a compromise of claims between
         ----------
the parties.


     6.  Civil Code Section 1542.  The parties declare that they have read and
         -----------------------
understand the following statutory language of Section 1542 of the California
Civil Code, which provides:


     A general release does not extend to claims which the creditor does not
     know or suspect to exist in his favor at the time of executing the release,
     which if known by him must have materially affected his settlement with
     debtor.

     Nevertheless, the parties hereby assume the risk of all unknown claims
against the other as provided herein and agree that this Agreement extends to
all claims of every nature and kind whether or not arising out of or relating to
any matters generally or specifically described above, whether such claims are
known or unknown, suspected or unsuspected, except for the Covenants.  All
rights under Section 1542 of the California Civil Code are hereby expressly
waived, except for the Covenants.


     7.  Sole Expression of Agreement.  Each party acknowledges and represents
         ----------------------------
that (a) any promise or representation not herein expressed is not being relied
upon in connection with this Agreement, and (b) this Agreement embodies all
terms and conditions concerning the release referred to herein and the
compromise and settlement of all direct or indirect obligations and disputes
between the parties, except for the Covenants. The recitals provided above are
hereby incorporated into this Agreement. This Agreement constitutes the final,
complete and exclusive agreement between the parties hereto pertaining to all
prior transactions and prior claims between them and supersedes any and all
prior and contemporaneous agreements or representations, except for the
Covenants.


     8.  No Further Waiver.  No waiver of any provision of this 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. No waiver shall be
binding unless executed in writing by the party making the waiver.


     9.  Attorneys' Fees Upon Breach.  If any legal action or other proceeding
         ---------------------------
arises from or relates to this Agreement, or any agreement or document delivered
under it, or for a declaration of rights and duties hereunder, or because of an
alleged dispute, breach, default or misrepresentation in connection with any
provision of this Agreement, the successful or prevailing party shall be
entitled to recover reasonable attorneys' fees and other costs incurred in

                                       2
<PAGE>

connection with that action or proceeding, in addition to any other relief to
which the party may be entitled.


     10.  Governing Law and Venue.  This Agreement is entered into in San Diego,
          -----------------------
California. This Agreement shall be interpreted and enforced under the internal
laws of the State of California. Any action or proceeding based upon, arising
out of or related to this Agreement may only be commenced or maintained in a
state court of appropriate jurisdiction located in San Diego, California.


     11.  Further Assurances.  Each of the parties hereto shall do all acts and
          ------------------
execute and deliver all documents necessary, convenient or desirable to carry
out all provisions of this Agreement. These shall include, but not be limited
to, the execution by TOI of all necessary transfers and assignments for all
equipment, vehicles, apartments or other items currently being leased by TOI to
WFI.


     12.  Construction.  The initial draft of this Agreement was drafted by the
          ------------
law firm of Procopio, Cory, Hargreaves & Savitch LLP ("Procopio"), which
represented WFI only in this transaction. Both parties acknowledge Procopio's
disclosure of its representation of TOI on other matters and waive any claims
they may have concerning actual or potential conflicts of interest. Procopio and
WFI have strongly urged TOI to retain separate independent legal counsel. Each
party has had the opportunity to consult independent counsel and either has done
so or has decided not to do so. This Agreement shall not be construed against
the party or its representative who drafted this Agreement or any portion
hereof. This Agreement shall be construed so that time is of the essence for
each of its provisions.


     13.  Binding Effect.  No claims have been assigned by any party prior to
          --------------
signing this Agreement. This Agreement shall bind and inure to the benefit of
the parties and their respective heirs, personal representatives, officers,
directors, attorneys, agents, successors and assigns. This Agreement may not be
modified except by a written agreement signed by the parties signing this
Agreement or their heirs, personal representatives, successors and assigns.


                             [Agreement Continues]

     14.  Counterparts.  This Agreement may be executed in any number of
          ------------
counterparts, all of which together shall constitute one (1) original agreement.
Faxed signatures shall be equivalent to original signatures.


     IN WITNESS WHEREOF, the parties have executed this Agreement as of the
Effective Date.
