EXHIBIT 4.1

                              AMENDED AND RESTATED

                           MPOWER HOLDING CORPORATION

                                STOCK OPTION PLAN

         1. Purpose and Effect of the Plan. This Stock Option Plan (the "Plan")
is intended to promote the interests of Mpower Holding Corporation, a Delaware
corporation (the "Company") and its owners by encouraging certain selected key
employees (including officers of the Company), consultants and Board of
Directors members who will be responsible for the future growth and continued
development of the Company to own, and to increase their ownership of, the
Company's Shares thereby giving them, as owners, an increased personal interest
in, and a greater concern for, the Company's success and progress. The Plan is
also intended to aid the Company in competing with other enterprises for the
services of new executives and key employees needed to help insure continued
development.

         2. Name. The Plan shall be known as "Amended and Restated Mpower
Holding Corporation Stock Option Plan."

         3. Definition of Terms. In addition to words and terms that may be
defined elsewhere in the Plan, the following words and terms as used in the Plan
shall have the following meanings unless the context or use fairly indicates
another or different meaning or intent, which definitions shall be equally
applicable to both the singular and plural forms of such words and terms.

            A. "Board" shall mean the Board of Directors of the Company.

            B. "Change of Control" shall mean:

         (a) The consummation of a merger or consolidation of the Company with
or into another entity or any other corporate reorganization, if more than 50%
of the combined voting power of the continuing or surviving entity's securities
outstanding immediately after such merger, consolidation or other reorganization
is owned by persons who were not stockholders of the Company immediately prior
to such merger, consolidation or other reorganization;

         (b) The sale, transfer or other disposition of all or substantially all
of the Company's assets;

         (c) A change in the composition of the Board, as a result of which
one-third or more of the incumbent directors are not directors who either (i)
had been directors of the Company on the date 24 months prior to the date of the
event that may constitute a Change in Control (the "original directors") or (ii)
were elected, or nominated for election, to the Board with the affirmative votes
of at least a majority of the aggregate of the original directors who were still
in office at the time of the election or nomination and the directors whose
election or nomination was previously so approved; or

<PAGE>

         (d) Any transaction as a result of which any person is the "beneficial
owner" (as defined in Rule 13d-3 under the Exchange Act), directly or
indirectly, of securities of the Company representing at least 50% of the total
voting power represented by the Company's then outstanding voting securities.
For purposes of this Subsection (d), the term "person" shall have the same
meaning as when used in Sections 13(d) and 14(d) of the Exchange Act but shall
exclude (i) a trustee or other fiduciary holding securities under an employee
benefit plan of the Company or of a Parent or Subsidiary and (ii) a corporation
owned directly or indirectly by the stockholders of the Company in substantially
the same proportions as their ownership of the common stock of the Company.

A transaction shall not constitute a Change in Control if its sole purpose is to
change the state of the Company's incorporation or to create a holding company
that will be owned in substantially the same proportions by the persons who held
the Company's securities immediately before such transaction.

            C. "Code" shall mean the Internal Revenue Code of 1986, as amended
from time to time.

            D. "Committee" shall have the meaning set forth in Item 5 hereof.

            E. "Common Stock" shall mean the common stock of the Company, $0.001
par value per share.

            F. "Employee" shall mean any employee of the Company, including
officers or directors of the Company who are employees of the Company.

            G. "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended.

            H. "Fair Market Value" shall mean the fair market value of a share
of Common Stock on a particular date determined as follows. In the event the
Company's Common Stock is listed upon an established stock exchange, Fair Market
Value shall be deemed to be the closing price of the Company's Common Stock on
such stock exchange on such date or, if no sale of the Company's Common Stock
shall have been made on any stock exchange on that day, the Fair Market Value
shall be determined as such price for the next preceding day upon which a sale
shall have occurred. In the event the Company's Common Stock is not listed upon
an established exchange but is quoted on the National Association of Securities
Dealers Automated Quotation System ("NASDAQ"), the Fair Market Value shall be
deemed to be the closing sale price (if included in the national market list) or
the mean between the closing dealer "bid" and "asked" prices for the Company's
Common Stock as quoted on NASDAQ for such date, and if no closing sale price or
"bid" and "asked" prices are quoted for that day, the Fair Market Value shall be
determined by reference to such prices on the next preceding day on which such
prices are quoted. In the event the Company's said Common Stock is neither
listed on an established stock exchange nor quoted on NASDAQ, the Fair Market
Value on such date shall be determined by the Committee.

            I. "ISO" shall mean any Option under this Plan which is intended to
be an incentive stock option under Code Section 422.

                                       2
<PAGE>

            J. "Non-Employee Director" shall have the meaning given that term by
Rule 16b-3 promulgated under the Exchange Act.

            K. "Non-Employees" shall mean any consultant of the Company or
director of the Company who is not an employee of the Company.

            L. "NQSO" shall mean any Option granted under this Plan which is not
intended to qualify as an incentive stock option under Code Section 422.

            M. "Option" shall mean a stock option, whether an ISO or NQSO,
granted under the Plan.

            N. "Option Price" shall mean the purchase price of a Share of Common
Stock under an Option.

            O. "Participant" shall mean an Employee or Non-Employee to whom an
Option is granted under the Plan.

            P. "Parent" shall mean any corporation which at the time qualifies
as a parent of the Company under the definition of "parent corporation"
contained in Code Section 424(c).

            Q. "SEC" shall mean the Securities and Exchange Commission.

            R. "Shares" shall represent the shares of Common Stock in the
Company that may be acquired by exercise of Options hereunder.

            S. "Subsidiary" shall mean any corporation which at the time
qualifies as a subsidiary of the Company under the definition of "subsidiary
corporation" contained in Code Section 424(f).

         4. Characterization of Options. Options granted in accordance with the
terms hereof within the limits prescribed by Item 9A(iv) hereof and which are
specified in the option agreement as intended to be incentive stock options, are
to be incentive stock options as provided in Code Section 422. All other Options
granted hereunder shall be nonqualified options as provided in Code Section 83.

         5. Administration. The Plan shall be administered by a Stock Option
Committee (the "Committee") consisting of not less than two members all of whom
shall be Non-Employee Directors.

            A. The Committee shall be appointed by the Board from its
membership. The members of the Committee shall serve at the pleasure of the
Board, which shall have the power, at any time and from time to time, to remove
members from the Committee or to add members thereto. Vacancies on the
Committee, however caused, shall be filled by the Board.

            B. The Committee may interpret the Plan, prescribe, amend and
rescind any rules and regulations necessary or appropriate for the
administration of the Plan and make such other determinations and take such
other action as it deems necessary or desirable for the

                                       3
<PAGE>

administration of the Plan and the protection of the Company except as otherwise
reserved to the Board or the stockholders of the Company. Without limiting the
generality of the foregoing, the Committee, in its discretion, may treat all or
any part of any period during which a Participant is on military duty or on an
approved leave of absence from the Company as a period of employment of such
Participant by the Company for purposes of accrual of his rights under his
Option. In addition, the Committee shall have the specific authority to grant
Options with different terms to different Participants and shall further have
the specific authority to require a minimum holding period between the grant and
exercise of any Option, to determine that the Options granted to a Participant
may be exercised only in installments, to accelerate the vesting of any Option
and to specify such conditions precedent to the exercise of any Option as the
Committee may deem advisable. The Committee may at any time, with the consent of
the Participant, at its sole discretion, cancel any Option and issue to the
Participant a new Option for any equivalent or lesser number of Shares, and at a
lesser Option Price. Any interpretation, determination or other action made or
taken by the Committee shall be final, binding and conclusive.

            C. No member of the Committee shall be liable for any action taken
or omitted or determination made in good faith with respect to the Plan or any
Option granted under the Plan.

         6. Shares Subject to Plan. Options may be granted by the Company from
time to time to purchase an aggregate of 12,960,000 Shares subject to adjustment
as provided in Item 11 below. The Shares issued upon exercise of Options granted
under the Plan may be authorized and unissued Shares or Shares repurchased by
the Company. If any Option granted under the Plan shall terminate, expire or,
with the consent of the Participant, be canceled as to any Shares, new Options
may thereafter be granted covering any such Shares. The Options granted to a
Participant in any single fiscal year shall not cover more than the total number
of Shares available for grant under the Plan, subject to adjustment as provided
in Item 11 below.

         7. Eligibility. Options may be granted to those Employees and
Non-Employees of the Company selected by the Committee in its sole discretion
from time to time who have and exercise key management functions for the Company
or who discharge other responsibilities important to the success of the Company.
Notwithstanding anything to the contrary in this Plan, Options may be granted to
a director who is a member of the Committee if otherwise exempt from Section
16(b) of the Exchange Act pursuant to Rule 16b-3, SEC interpretations thereof or
any subsequently promulgated rule or regulation. The granting of an Option to
any Participant shall neither entitle such Participant to, nor disqualify such
Participant from participation in any future Option grants.

         8. Grant of Options. The Committee shall have the authority, subject to
the terms of the Plan, to: (a) determine and designate from time to time those
key employees (including officers), consultants and directors to whom Options
are to be granted; (b) determine the number of Shares subject to each Option;
(c) determine the duration of the exercise period for any Option; (d) determine
that the Options granted to a Participant may be exercised only in installments;
and (e) specify such other terms and conditions of each Option as the Committee
in its sole discretion deems advisable. The date of grant of an Option under the
Plan will be the date on which the Option is awarded by the Committee.

                                       4

         9. Terms and Conditions of Options. Each Option shall be evidenced by
an Option Agreement which shall contain such terms and conditions consistent
with the provisions of the Plan as may be approved by the Committee and shall be
signed by an officer of the Company and the Participant. Each Option granted
under the Plan shall be subject to such terms and conditions as follows:

            A. Terms of ISO's. ISO's granted hereunder shall be subject to the
terms and conditions contained in subparagraphs (i)-(viii) below and to such
other terms and conditions as the Committee may deem appropriate; provided,
however, that no Option that is intended to qualify as an ISO shall be subject
to any condition that is inconsistent with the provisions of Code Section
422(b).

                  (i) Option Period. Each ISO Option Agreement shall specify the
         period during which the ISO thereunder is exercisable (which shall not
         exceed ten years from the date of grant) and shall provide that the ISO
         shall expire at the end of such period.

                  (ii) Option Price. The Option Price per share shall be
         determined by the Committee at the time any ISO is granted and shall
         not be less than one hundred percent (100%) of the Fair Market Value of
         a share of Common Stock on the date that the ISO is granted. Such price
         shall be subject to adjustment as provided in Item 11.

                  (iii) Ten Percent Stockholders. ISO's shall not be granted to
         any Employee who, immediately before the ISO is granted, owns stock
         possessing more than ten percent (10%) of the total combined voting
         power of all classes of stock of the Company [or of its Parent] or
         Subsidiary; provided, however, that this prohibition shall not apply if
         at the time such ISO is granted the Option Price is at least one
         hundred and ten percent (110%) of the Fair Market Value of the Common
         Stock and such ISO is not exercisable after the expiration of five (5)
         years from the date such ISO is granted.

                  (iv) Limit on Incentive Stock Options. To the extent the
         aggregate Fair Market Value of the shares (valued at the time of grant
         in accordance with subparagraph (ii) above) with respect to which ISO's
         (determined without regard to this subparagraph (iv)) are exercisable
         for the first time by any individual during any calendar year (under
         all incentive stock option plans of the Company and any Parent and
         Subsidiary) exceeds $100,000, such ISO's in excess of $100,000 shall be
         treated as Options which are NQSO's. This subparagraph (iv) shall be
         applied by taking ISO's into account in the order in which they were
         granted.

                  (v) Termination of Employment other than as a Result of Death
         or Disability. An ISO of any Participant who shall cease to be an
         Employee other than as a result of his death or disability (as defined
         in (vi) below) shall be exercisable only to the extent exercisable on
         the date of termination of employment and must be exercised on or
         before the option expiration date

                                       5
<PAGE>

         specified in the Option Agreement but in no event later than the date
         that is three (3) months following the date of termination of
         employment. To the extent any ISO is not exercisable on the date of
         termination of employment, such ISO shall terminate on the date of
         termination of employment. To the extent any ISO is not exercised
         within the time period provided, such ISO shall terminate as of the
         date of expiration of such time period. Nothing in the Plan shall be
         construed as imposing any obligation on the Company to continue the
         employment of any Participant or shall interfere or restrict in any way
         the rights of the Company to discharge any Employee at any time for any
         reason whatsoever, with or without cause.

                  (vi) Termination of Employment as a Result of Death or
         Disability. In the event of the death or disability of the Participant
         while in the employ of the Company, the personal representative of the
         Participant (in the event of his death) or the Participant (in the
         event of his disability) may, subject to the provisions hereof and
         before the date (the "Option Termination Date") specified in the ISO
         Option Agreement, which date is not later than the earlier of the ISO's
         expiration date or the expiration of one (1) year after the date of
         such death or disability, exercise the ISO granted to such Participant
         to the same extent the Participant might have exercised such ISO on the
         date of his death or disability, but, unless otherwise provided in the
         ISO Option Agreement, not further or otherwise. To the extent any ISO
         is not, and does not in accordance with the terms of the Option
         Agreement become, exercisable as of the date of the death or disability
         of Participant, such ISO shall terminate on the date of death or
         disability. To the extent any ISO is not exercised within the time
         period provided, such ISO shall terminate as of the date of expiration
         of such time period. Fur purposes of this subparagraph (vi), a
         Participant shall be considered to be subject to a disability when such
         Participant is disabled within the meaning of Code Section 22(e)(3),
         and the date of any such disability shall be deemed to be the date
         following the last day the Participant performed services for the
         Company.

                  (vii) Period to Exercise Option. Any ISO granted hereunder
         may, prior to its expiration or termination, be exercised from time to
         time, in whole or in part, up to the total number of shares with
         respect to which it shall have then become exercisable. An ISO granted
         hereunder may become exercisable in installments as determined by the
         Committee; provided, however, that if the Committee grants an ISO or
         ISO's exercisable in more than one installment, and if the employment
         of a Participant holding such ISO is terminated, then unless the ISO
         Option Agreement provides otherwise, the ISO shall be exercisable in
         accordance with the terms of subparagraph (v) or (vi) only as to such
         number of shares as to which the Participant had the right to exercise
         the ISO on the date of termination of employment.

                  (viii) Non-Employees. No ISO may be granted to any person who
         is a Non-Employee.

                                       6
<PAGE>

            B. Terms of NQSO's. NQSO's granted hereunder shall be subject to the
terms and conditions contained in subparagraphs (i)-(iii) below and to such
other terms and conditions as the Committee may deem appropriate.

                  (i) Option Period. Each NQSO Option Agreement shall specify
         the period during which the Option thereunder is exercisable (which
         shall not exceed ten years from the date of grant) and shall provide
         that the NQSO shall expire at the end of such period.

                  (ii) Option Price. The Option Price per Share shall be
         determined by the Committee at the time any NQSO is granted. Such price
         shall be subject to adjustments as provided in Item 11.

                  (iii) Period to Exercise Option. Any NQSO granted hereunder
         may, prior to its expiration or termination, be exercised from time to
         time, in whole or in part, up to the total number of Shares with
         respect to which it shall have then become exercisable. An NQSO granted
         hereunder may become exercisable in installments as determined by the
         Committee; provided, however, that if the Committee grants an Option
         exercisable in more than one installment, and if the employment of an
         Employee-Participant holding such Option is terminated, then unless the
         Option Agreement provides otherwise, the Option shall be exercisable
         only as to such number of Shares as to which the Participant had the
         right to exercise the Option on the date of termination of employment.

                  (iv) Restrictions on Grants to Non-Employee Directors. Any
         NQSO granted hereunder to a Non-Employee Director shall provide that
         the Shares received upon exercise of the Option may not be disposed of
         before the first day following the six month anniversary of the date
         the Option was granted.

         10. Exercise of Option. The exercise of any Option under the Plan shall
be subject to the provisions of Paragraphs A, B and C below.

            A. Method of Exercising Option. Any Option granted hereunder or any
portion thereof (in whole Shares only) may be exercised by the Participant by
(i) delivering to the Company at its main office (attention its Secretary,
Assistant Secretary or Chief Financial Officer) written notice which shall set
forth the Participant's election to exercise a portion or all of his Option, the
number of Shares with respect to which the Option rights are being exercised,
and such other representations and agreements as may be required by the Company
to comply with applicable securities laws and loan agreements to which the
Company is a party, and (ii) paying in full the Option Price of the Shares
purchased. Upon receipt of such notice and payment, the Company shall issue and
deliver to the Participant a certificate for the number of Shares with respect
to which Options were so exercised. In the Option Agreement, the Committee may
require the exercise of Options by any Participant to comply with the
requirements of the SEC.

            B. Payment of Option Price. The Option Price of the Shares as to
which an Option is exercised shall be paid in full to the Company at the time of
exercise. The payment

                                       7
<PAGE>

may be made either in cash or its equivalent or, where permitted by law and
approved by the Committee in its sole discretion: (i) by delivery of a
promissory note on terms and conditions acceptable to the Committee; (ii) by
cancellation of indebtedness of the Company to the Participant; (iii) by
surrender of shares of Common Stock of the Company having a Fair Market Value
equal to the exercise price of the Option; (iv) by instructing the Company to
withhold shares otherwise issuable pursuant to an exercise of an Option having a
Fair Market Value equal to the exercise price of the Option (including withheld
shares); (v) by waiver of compensation due or accrued to the Participant for
services rendered; or (vi) by any other means approved by the Committee.
Participants who are not Employees shall not be entitled to purchase Shares with
a promissory note unless the note is adequately secured by collateral other than
the Shares so purchased.

               Notwithstanding anything to the contrary above, the Committee, in
its discretion, may suspend or terminate the right of participants to pay in a
form other than cash should the Committee deem such action to be in the best
interests of the Company.

            C. Withholding Taxes. The Company may, in its discretion, require a
Participant to pay to the Company at the time of exercise the amount that the
Company deems necessary to satisfy its obligation to withhold federal, state or
local income or other taxes incurred by reason of the exercise. Where the
exercise of an Option does not give rise to an obligation to withhold federal
income taxes on the date of exercise, the Company may, in its discretion,
require a Participant to place Shares purchased under the Option in escrow for
the benefit of the Company until such time as federal income tax withholding is
required on amounts included in the gross income of the Participant as a result
of the exercise of an Option or the disposition of Shares acquired pursuant
thereto. At such time, the Company, in its discretion, may require the
Participant to pay to the Company the amount that the Company deems necessary to
satisfy its obligation to withhold federal, state or local income or other taxes
incurred by reason of the exercise of the Option or the disposition of Shares,
in which case the Shares will be released from escrow to the Participant.

            D. No Fractional Shares. Notwithstanding anything herein to the
contrary, no fractional Shares may be issued under the Plan.

         11. Capital Adjustments. The number and price of Shares covered by each
Option, the number of Shares that become exercisable at any one time and the
total number of Shares that may be optioned and sold under the Plan shall be
proportionately adjusted to reflect any Share dividend, Share split or Share
combination or any recapitalization of the Company. No Option granted pursuant
to this Plan which was intended to be an incentive stock option at the time of
grant shall be adjusted in a manner that causes the Option to fail to qualify as
an incentive stock option within the meaning of Code Section 422. Except as
expressly provided in this Item 11, the Participant shall have no rights by
reason of any change in the Shares of the Company. The grant of an Option
pursuant to this Plan shall not affect in any way the right or power of the
Company to make adjustments, reclassifications, reorganizations or changes of
its capital or business structure or to merge, consolidate, dissolve, liquidate,
sell or transfer all or any part of its business or assets. The Committee shall
have the sole discretion to make all interpretations and terminations required
under this Item to the extent it deems equitable and appropriate.

                                       8
<PAGE>

         12. Effect of Change of Control. Every Option granted under this Plan
shall become immediately exercisable as to all of the Common Shares subject to
such Option upon the first to occur of: (a) a Change of Control with respect to
the Company, or (b) approval by the stockholders of the Company of a transaction
which would constitute a Change of Control.

         13. Company's Right to Redeem Options. Any provision of this Plan to
the contrary notwithstanding, in the event the Company is a party to an
agreement to sell all or substantially all of its assets, a merger or other
reorganization, all outstanding Options shall be subject to the agreement of
sale, merger or reorganization which may provide, without limitation, for the
assumption of outstanding Options by the surviving corporation or its Parent,
for their continuation by the Company (if it is the surviving corporation), for
accelerated termination and redemption of Options in stock or cash, or for other
arrangements which provide the Participant with a per share economic benefit at
least equal to the difference between the fair market value (as reasonably
determined by the Board) of the consideration received for each Share in the
transaction and the Option Price.

         14. Reservation of Shares. The Company, during the term of any Options
granted hereunder, will at all times reserve and keep available, and will seek
to obtain from any regulatory body having jurisdiction any requisite authority
in order to issue and sell such number of Shares as shall be sufficient to
satisfy the requirements of the Options granted under the Plan. If, in the
opinion of the Company's counsel, the issuance or sale of any Shares hereunder
shall not be lawful for any reason, including the inability of the Company to
obtain from any regulatory body having jurisdiction authority deemed by such
counsel to be necessary for such issuance or sale, the Company shall not be
obligated to issue or sell any such Shares.

         15. Securities Laws. Upon the exercise of an Option at a time when
there is not in effect under the Securities Act of 1933, as amended (the "Act"),
a current registration statement relating to the Shares to be received upon such
exercise, the Participant shall represent and warrant in writing to the Company
that the Shares purchased are being acquired for investment and not with a view
to the distribution thereof and shall agree to the imposition of a legend on the
certificate or certificates representing said Shares in substantially the
following form and such other restrictive legends as are required or advisable
under the provision of any applicable laws:

                  This share certificate and the Shares represented hereby have
                  not been registered under the Securities Act of 1933, as
                  amended (the "Act"), nor under the securities laws of any
                  state and shall not be transferred at any time in the absence
                  of (i) an effective registration statement under the Act and
                  any other applicable state law with respect to such Shares at
                  such time; or (ii) an opinion of counsel satisfactory to the
                  Company and its counsel to the effect that such transfer at
                  such time will not violate the Act or any applicable state
                  securities laws; or (iii) a "no action" letter from the
                  Securities and Exchange Commission and a comparable ruling
                  from any applicable state agency with respect to such state's
                  securities laws.

                  No Shares shall be issued or sold upon the exercise of any
Option unless and until (i) the full amount of the purchase price has been paid
as provided in Item 10 hereof and (ii) the then applicable requirements of the
Act, the applicable securities laws of any other jurisdiction, as any of the
same may be amended, the rules and regulations of the SEC and any other
regulations of any securities exchange on which the Shares may be listed shall
have been fully complied with and satisfied.

         16. Transferability and Options. No Option shall be assignable or
transferable by a Participant except by will or by the laws of descent and
distribution. Any distributee by will or by the laws of descent and distribution
shall be bound by the provisions of the Plan. During the life of a Participant,
the Option shall be exercisable only by such Participant. Any attempt to assign,
pledge, transfer, hypothecate or otherwise dispose of an Option and any levy,
execution, attachment or similar process on an Option shall be null and void.

         17. No Rights as Stockholders. A Participant shall not have any rights
as a stockholder with respect to any Shares covered by any Option granted
hereunder until the issuance of a certificate for such Shares. No adjustment
shall be made on the issuance of a share certificate to a Participant as to any
distributions or other rights for which the record date occurred prior to the
date of issuance of such certificate.

         18. Indemnification and Exculpation. Each person who is or shall have
been a member of the Management Committee or of the Committee shall be
indemnified and held harmless by the Company against and from any and all loss,
costs, liability or expense that may be imposed upon or reasonably incurred by
him in connection with or resulting from any claim, action, suit or proceeding
to which he may be or become involved by reason of any action taken or failure
to act under the Plan and against and from any and all amounts paid by him in
settlement thereof (with the Company's written approval) or paid by him in
satisfaction of a judgment in any such action, suit or proceeding, except a
judgment in favor of the Company based upon a finding of his lack of good faith;
subject, however, to the condition that upon the institution of any claim,
action, suit or proceeding against him, he shall in writing give the Company an
opportunity, at its expense, to handle and defend the same before he undertakes
to handle and defend it on his own behalf. The foregoing right of
indemnification shall not be exclusive of any other right to which such person
may be entitled as a matter of law or otherwise, or any power that the Company
may have to indemnify him or hold him harmless. Each member of the Board or of
the Committee and each officer and employee of the Company shall be fully
justified in relying or acting in good faith upon any information furnished in
connection with the administration of the Plan by any appropriate person or
persons other than himself. In no event shall any person who is or shall have
been a member of the Board or of the Committee, or an officer or employee of the
Company, be held liable for any determination made, or other action taken, or
any omission to act in reliance upon any such information as referred to in the
preceding sentence, or for any action (including the furnishing of information)
taken, or any omission to act, when any such determination, action or omission
is made in good faith.

         19. Use of Proceeds. Proceeds from the sale of Shares pursuant to
Options granted under the Plan shall constitute general funds of the Company.

                                       10
<PAGE>

         20. Amendment and Discontinuance. The Board of the Company may
terminate or amend the Plan in any respect at any time, except that no action of
the Board may alter or impair a Participant's rights under any outstanding
Option without his consent and, without the prior approval of a majority
interest of the stockholders: (i) the total number of shares that may be
optioned and sold under the Plan may not be increased (except by adjustment
pursuant to Item 11); (ii) the expiration date of the Plan may not be extended;
(iii) the class or persons eligible to participate in the Plan may not be
changed; (iv) the benefits accruing to the Participants under the Plan may not
be materially increased; and (v) the requirements for eligibility to participate
in the Plan may not be materially modified.

         21. Term of Plan. The Plan shall be effective as of the date of the
adoption of the Plan by the Board and stockholders of the Company and shall
expire on June __, 2006, unless sooner terminated as provided in Item 20 hereof.

         22. General. Except as the same may be governed by the Code and any
applicable federal securities laws, the Plan and any Options granted hereunder
shall be governed by and construed in accordance with the laws of the State of
Nevada. The granting of an Option shall impose no obligation upon the
Participant to exercise such Option. As herein used, the singular number shall
include the plural, the plural the singular, and the use of any gender shall be
applicable to all genders, unless the context or use shall fairly require a
different construction. Section or paragraph headings are employed herein solely
for convenience of reference, and such headings shall not affect the validity,
meaning or enforceability of any provision of the Plan. All references herein to
"Item" or "paragraph" shall mean the appropriately numbered Item or paragraph of
the Plan except where reference is made to the Code or any other specified law

AS APPROVED BY THE BOARD OF DIRECTORS OF THE COMPANY ON JULY 3, 2001.EXHIBIT 4.2

                         PRIMARY NETWORK HOLDINGS, INC.
                                STOCK OPTION PLAN

         1. Purpose of the Plan.

            The Primary Network Holdings, Inc. Stock Option Plan (the "Plan") is
intended to further the growth, development and financial success of Primary
Network Holdings, Inc. (the "Company") by providing incentives to its employees
and consultants to contribute toward the growth and profitability of the Company
and to assist the Company in obtaining and retaining the services of employees
and consultants with the ability to make such contributions. It is intended that
certain options to purchase Common Stock of the Company, par value $0.001 per
share ("Common Stock") granted hereunder will qualify as Incentive Stock Options
within the meaning of Section 422 of the Internal Revenue Code of 1986 as
amended (the "Code") ("Incentive Stock Options") and that other options granted
hereunder will not qualify as Incentive Stock Options ("non-qualified options,"
and, together with Incentive Stock Options, "options").

         2. Stock Subject to the Plan.

            (a) Stock Available for Grants of Options. Subject to adjustment
under Paragraph 15, the total number of shares of Common Stock that may be
issued pursuant to options granted under the Plan shall not exceed 3,468,820
shares of Common Stock. If any option shall expire or terminate for any reason
without having been exercised in full, the unpurchased shares subject thereto
shall again be available for the purposes of the Plan. Any shares of Common
Stock which are used as full or partial payment to the Company by an optionee of
the purchase price upon exercise of an option shall again be available for the
purposes of the Plan.

            (b) Reservation of Shares. The Company will allocate and reserve the
maximum number of shares under subparagraph (a) above out of its authorized but
unissued shares of Common Stock or treasury shares held by the Company,
including shares purchased in the open market or in private transactions.

         3. Administration.

            The Plan shall be administered by the Board of Directors of
the Company (the "Board") or any committee appointed by, and consisting solely
of members of, the Board. Subject to the express provisions of the Plan, the
Board (or the committee thereof) shall have complete authority, in its sole
discretion, to determine the individuals to whom, and the time or times at
which, options shall be granted, the number of shares to be subject to each
option and, subject to the provisions of the Plan, the terms and conditions
thereof. In making such determination, the Board (or the committee thereof) may
take into account the nature of the services rendered by the respective
individuals, their present and potential contributions to the Company's success
and such other factors as the Board (or the committee thereof), in its sole
discretion, shall deem relevant. Subject to the express provisions of the Plan,
the Board (or the

<PAGE>

committee thereof) shall also have complete authority to interpret the Plan, to
prescribe, amend and rescind rules and regulations relating to it, to determine
the terms and provisions of the respective stock option agreements (which need
not be identical) and to make all other determinations necessary or advisable
for the administration of the Plan. The Board's (or the committee's)
determinations on the matters referred to in this Paragraph 3 shall be
conclusive.

         4. Eligibility.

            Options (including Incentive Stock Options) may be granted only to
employees and consultants of the Company or its subsidiaries as determined by
the Board (or the committee thereof). As used herein, the following definitions
shall apply:

         (a) The term "consultant" means any natural person who is engaged by
         the Company or any subsidiary to render services and is compensated for
         such services (as contemplated by Rule 701 and Form S-8 promulgated
         under the Securities Act of 1933, as amended (the "Securities Act")).

         (b) The term "employee" means any person employed by the Company or any
         subsidiary of the Company, with the status of employment determined
         based upon such minimum number of hours or periods worked as shall be
         determined by the Board (or the committee thereof) in its sole
         discretion, subject to any requirements of the Code.

         (c) The term "optionee" means any employee or consultant who receives
         an option under the Plan.

         (d) The term "subsidiary" shall mean any present or future subsidiary
         corporation of the Company within the meaning of Section 424(f) of the
         Code.

         5. Time of Granting of Options.

            An option grant under the Plan shall be deemed to be made on the
date on which the Board (or the committee thereof), by formal action of its
members duly recorded in the records thereof, makes an award of an option to an
eligible employee or consultant of the Company; provided that such option is
evidenced by a written option agreement (an "Option Agreement") duly executed on
behalf of the Company and on behalf of the optionee promptly after the date of
the Board (or the committee thereof) action.

         6. Option Prices.

            The purchase price of the Common Stock under each option shall not
be less than 100% of the fair market value of the Common Stock at the time of
the granting of the option, and in no event shall be less than $1.52 per share,
subject to adjustment in accordance with Paragraph 15 hereof. In the case of an
optionee who owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of its parent or subsidiary
corporation, the purchase price of the Common Stock under each Incentive Stock
Option shall not be less than 110% of the fair market value of the Common Stock
at the time of the granting of the option. The Board (or the committee thereof)
may adopt criterion for the determination of such fair market value as it may
determine to be appropriate and as may be provided for by the

                                       2
<PAGE>

Board (or the committee thereof) or as may be required in order to comply with,
or to conform to the requirements of, any applicable laws or regulations.

         7. Method of Exercise.

            Upon exercise of options granted hereunder, the purchase price is to
be paid in full either (i) in cash, (ii) in the discretion of the Board (or the
committee thereof), by the tender to the Company of shares of the Common Stock
of the Company, owned by the optionee and registered in his or her name, having
a fair market value (determined at the time an option is granted in the same
manner as provided for in Paragraph 6 hereof) equal to the cash exercise price
of the option being exercised, (iii) in the discretion of, and upon the terms
and conditions approved by, the Board (or the committee thereof), by having
shares of Common Stock subject to such option withheld or exercising pursuant to
a "cashless exercise" procedure, or (iv) in the discretion of the Board (or the
committee thereof), by any combination of the payment methods specified in
clauses (i), (ii) and (iii) hereof; provided, however, that no shares of Common
Stock may be tendered in exercise of an option if such shares were acquired by
the optionee through the exercise of an Incentive Stock Option unless (A) such
shares have been held by the optionee for at least one year, and (B) at least
two years have elapsed since such Incentive Stock Option was granted; and
provided further that no option may be exercised for a fraction of a share of
Common Stock. The cash proceeds of the sale of Common Stock issued upon exercise
of options granted hereunder shall be added to the general funds of the Company
and used for its general corporate purposes. The shares of Common Stock of the
Company received by the Company as payment of the option price may be added to
the shares of the Common Stock of the Company held in its treasury and used for
the purposes of granting additional options under the Plan.

            Upon the exercise of an option which is not an Incentive Stock
Option, the Company may withhold a number of shares sufficient to satisfy the
Company's obligation to withhold for federal and state taxes on such exercise.

            The holder of an option shall have none of the rights of a
stockholder of the Company with respect to the shares subject to such option
until such shares shall have been issued to such holder upon the exercise of the
option in accordance with this Paragraph 7.

         8. Incentive Stock Option Amount Limit.

            The maximum aggregate fair market value (determined at the time an
option is granted in the same manner as provided for in Paragraph 6 hereof) of
the Common Stock of the Company with respect to which Incentive Stock Options
are exercisable for the first time by any optionee during any calendar year
(under all plans of the Company and its subsidiaries) shall not exceed $100,000.

         9. Term of Options.

            The term of each option shall be the term stated in the Option
Agreement; provided, however, that the term shall be no more than ten (10) years
from the date of granting thereof or such shorter period as is prescribed in
Paragraph 10 hereof; provided further that, in the case of an optionee who owns
more than ten percent (10%) of the total combined voting

                                       3
<PAGE>

power of all classes of stock of the Company or of its parent or subsidiary
corporation, the term of any Incentive Stock Option shall not be more than five
(5) years from the date of granting thereof or such shorter period as is
prescribed in Paragraph 10 below. Within such limit and subject to Paragraphs 10
and 11 hereof, options will be exercisable at such time or times, and subject to
such restrictions and conditions, as the Board (or the committee thereof) shall,
in each instance, approve, which need not be uniform for all optionees. At any
time after the grant of an option, the Board (or the committee thereof) may, in
its sole discretion and subject to the terms and conditions it may determine,
accelerate the period during which such option vests.

         10. Termination of Employment or Consulting Relationship.

            (a) In the event of termination of an optionee's continuous status
as an employee or consultant (but not in the event of an optionee's change of
status from employee to consultant (in which case an employee's Incentive Stock
Option shall automatically convert to a non-qualified option on the ninety-first
(91st) day following such change of status) or from consultant to employee),
such optionee may, but only within such period of time as is determined by the
Board (or the committee thereof) and in no event later than the expiration date
of the term of such option as set forth in the Option Agreement (with such
determination in the case of an Incentive Stock Option not exceeding three (3)
months after the date of such termination), exercise his or her option to the
extent that optionee was entitled to exercise it at the date of such
termination. To the extent that optionee was not entitled to exercise the option
at the date of such termination, or if optionee does not exercise such option to
the extent so entitled within the time specified herein, the option shall
terminate.

            (b) In the event of the termination of an optionee's continuous
status as an employee or consultant as a result of his or her disability (as
defined below), the optionee may exercise an option, to the extent he or she was
entitled to exercise it at the date of such termination, within such period of
time as is determined by the Board (or the committee thereof) (which, in the
case of an Incentive Stock Option, shall be no later than one (1) year after the
termination of employment) and in no event later than the expiration of the term
of the option as set forth in the Option Agreement. For this purpose, a person
shall be deemed to be "disabled" if he or she is permanently and totally
disabled within the meaning of Section 22(e)(3) of the Code, which, as of the
date hereof, means that he or she is unable to engage in any substantial gainful
activity by reason of any medically determinable physical or mental impairment
which can be expected to result in death or which has lasted or can be expected
to last for a continuous period of not less than 12 months. A person shall be
considered disabled only if he or she furnishes such proof of disability as the
Board (or the committee thereof) may require. To the extent that optionee was
not entitled to exercise the option at the date of such termination, or if
optionee does not exercise such option to the extent so entitled within the time
specified herein, the option shall terminate.

            (c) As used herein, "continuous status as an employee or consultant"
means that the employment or consulting relationship with the Company or any
subsidiary is not interrupted or terminated. Continuous status as an employee or
consultant shall not be considered interrupted in the case of (i) any leave of
absence approved by the Company or (ii) transfers between locations of the
Company, any subsidiary or any successor. A leave of absence approved by the
Company shall include sick leave, military leave, or any other personal

                                       4
<PAGE>

leave approved by an authorized representative of the Company. For purposes of
Incentive Stock Options, no such leave may exceed 90 days, unless reemployment
upon expiration of such leave is guaranteed by statute or contract, including
Company policies. If reemployment upon expiration of a leave of absence approved
by the Company is not so guaranteed, on the 91st day of such leave any Incentive
Stock Option held by the optionee shall cease to be treated as an Incentive
Stock Option and shall be treated for tax purposes as a non-qualified option.
The Option Agreements may contain such provisions as the Board (or the committee
thereof) shall approve with reference to the effect of approved leaves of
absence.

            (d) Nothing in the Plan or in any option granted pursuant to the
Plan shall confer on any individual any right to continue in the employment of,
or consulting relationship with, the Company, any subsidiary or affiliate
thereof or to interfere in any way with the right of the Company, any subsidiary
or affiliate thereof to terminate his or her employment or consulting
relationship at any time, with or without cause.

         11. Death.

            In the event of the death of an individual to whom an unexpired
option has been granted under the Plan, the unexpired option may be exercised,
to the extent exercisable at the date of death, by a legatee or legatees under
the optionee's last will, or by personal representatives or distributees, at any
time within a period of one (1) year after death, but not after the expiration
of the term of the option, and only if and to the extent that the option was
exercisable at the date of death.

         12. Successive Option Grants.

             Successive option grants may be made to any optionee under this
Plan.

         13. Non-Transferability of Options, Transfer Restrictions on Option
Shares.

            (a) Each option granted under the Plan shall, by its terms, be
non-transferable otherwise than by will or the laws of descent and distribution,
and an option may be exercised, during the lifetime of the holder thereof, only
by such holder. The terms of such option shall be binding upon the
beneficiaries, executors, administrators, heirs and successors of such holder.

            (b) The Board (or the committee thereof), in its sole discretion,
may impose such restrictions on the ownership and transferability of the shares
purchasable upon the exercise of an option as it deems appropriate. Any such
restriction shall be set forth in the respective Option Agreement and may be
referred to on the certificates evidencing such shares. The Board (or the
committee thereof) may require the optionee to give the Company prompt notice of
any disposition of shares of Common Stock acquired upon exercise of an Incentive
Stock Option within (i) two years from the date of granting such option to such
optionee or (ii) one year after the transfer of such shares to such optionee.
The Board (or the committee thereof) may direct that the certificates evidencing
shares acquired upon exercise of an option refer to such requirement to give
prompt notice of disposition.

                                       5
<PAGE>

         14. Investment Purpose.

            Each option under the Plan shall be granted only on the condition
that all purchases of stock thereunder shall be for investment purposes, and not
with a view to resale or distribution, except that the Board (or the committee
thereof) may make such provision with respect to options granted under this Plan
as it deems necessary or advisable for the release of such condition upon the
registration with the Securities and Exchange Commission of Common Stock subject
to the option, or upon the happening of any other contingency warranting the
release of such condition.

         15. Adjustments Upon Changes in Capitalization or Corporate
Acquisitions.

            Notwithstanding any other provisions of the Plan, the option
agreements may contain such provisions as the Board (or the committee thereof)
shall determine to be appropriate for the adjustment of the number and class of
shares subject to each outstanding option, and the option prices in the event of
changes in the outstanding Common Stock by reason of stock dividends,
recapitalizations, mergers, consolidations, spin-offs, split-offs, split-ups,
combinations or exchanges of shares and the like, and, in the event of any such
change in the outstanding Common Stock, the aggregate number and class of shares
available under the Plan and the maximum number of shares as to which options
may be granted to any individual shall be appropriately adjusted by the Board
(or the committee thereof), whose determination shall be conclusive. In the
event the Company enters into a transaction described in Section 424(a) of the
Code with any other corporation, the Board (or the committee thereof) may grant
options to employees or former employees, or consultants or former consultants
of such corporation in substitution of options previously granted to them upon
such terms and conditions as shall be necessary to qualify such grant as a
substitution described in Section 424(a) of the Code.

         16. Amendment and Termination.

            The Board (or the committee thereof) may at any time terminate the
Plan, or make such modifications of the Plan as they shall deem advisable;
provided, however, that the Board (or the committee thereof) may not, without
further approval by the holders of Common Stock, make any modifications which,
by applicable law, require such approval. No termination or amendment of the
Plan may, without the consent of the optionee to whom any option shall
previously have been granted, adversely affect the rights of such optionee under
such option.

         17. Term of Plan.

            This Plan shall terminate ten (10) years after the date on which it
was initially approved and adopted by the Board (or the committee thereof) and
no option shall be granted hereunder after the expiration of such ten-year
period. Options outstanding at the termination of the Plan shall continue in
full force and effect and shall not be affected thereby.

         18. Compliance with Laws.

            This Plan, the granting and vesting of options under this Plan and
the issuance and delivery of shares of Common Stock and the payment of the
exercise price under this Plan or under options granted hereunder are subject to
compliance with all applicable federal and state

                                       6
<PAGE>

laws, rules and regulations (including but not limited to state and federal
securities law and federal margin requirements) and to such approvals by any
listing, regulatory or governmental authority as may, in the opinion of counsel
for the Company, be necessary or advisable in connection therewith. Any
securities delivered under this Plan shall be subject to such restrictions, and
the person acquiring such securities shall, if requested by the Company, provide
such assurances and representations to the Company as the Company may deem
necessary or desirable to assure compliance with all applicable legal
requirements. To the extent permitted by applicable law, the Plan and the
options granted hereunder shall be deemed amended to the extent necessary to
conform to such laws, rules and regulations.

         19. Paragraph Headings.

            Paragraph headings are provided herein for convenience only and are
not to serve as a basis for interpretation or construction of this Plan.

         20. Governing Law.

            This Plan and any agreements hereunder shall be administered,
interpreted and enforced under the internal laws of the State of Delaware
without regard to conflicts of laws thereof.
