2000 STOCK INCENTIVE PLAN

 Exhibit 4.1

SOHU.COM INC.

2000 STOCK INCENTIVE PLAN

(as amended)

 

                1.      Purpose.   This 2000 Stock Incentive Plan (the
"Plan") is intended to provide incentives: (a) to the officers and other employees of Sohu.com Inc., a Delaware corporation (the "Company"), and any present or future parent or subsidiaries of the Company (collectively,
"Related Corporations") by providing them with opportunities to purchase stock in the Company pursuant to options granted hereunder which qualify as "incentive stock options" under Section 422(b) of the Internal Revenue Code of
1986, as amended (the "Code") ("ISO" or "ISOs"), (b) to directors, officers, employees, consultants and advisors of the Company and Related Corporations by providing them with (i) opportunities to purchase stock in
the Company pursuant to options granted hereunder which do not qualify as ISOs ("Non-Qualified Option" or "Non-Qualified Options") or (ii) by providing them with opportunities to make direct purchases of common stock of the
Company ("Restricted Stock Purchases"). Both ISOs and Non-Qualified Options are referred to hereafter individually as an "Option" and collectively as "Options." Options and Restricted Stock Purchases are referred to
hereafter individually as a "Stock Right" and collectively as "Stock Rights." As used herein, the terms "parent" and "subsidiary" mean "parent corporation" and "subsidiary corporation,"
respectively, as those terms are defined in Section 424 of the Code. 

                2.      Administration of the Plan. 

                A.     Board or Committee Administration.   The Plan shall be
administered by the Board of Directors of the Company (the "Board"). The Board may appoint a Compensation Committee (as the case may be, the "Committee") of two (2) or more of its members to administer the Plan and to grant Stock
Rights hereunder, provided such Committee is delegated such powers in accordance with applicable state law. (All references in this Plan to the "Committee" shall mean the Board if no such Compensation Committee has been so appointed). If
the Company registers any class of any equity security pursuant to Section 12 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Plan shall be administered in accordance with the applicable rules set forth in Rule
16b-3 or any successor provisions of the Exchange Act or the rules under the Exchange Act or any such successor provision ("Rule 16b-3"). From and after the date the Company becomes subject to Section 162(m) of the Code with respect
to compensation earned under the Plan, each member of the Committee shall also be an "outside director" within the meaning of Section 162(m) of the Code and the regulations promulgated thereunder.

                B.      Authority of Board or Committee.   Subject to the
terms of the Plan, the Committee shall have the authority to: (i) determine the employees of the Company and Related Corporations (from among the class of employees eligible under paragraph 3 to receive ISOs) to whom ISOs may be granted, and to
determine (from among the class of individuals and entities eligible under paragraph 3 to receive Non-Qualified Options and to make purchases of Restricted Stock) to whom Non-Qualified Options or rights to make Restricted Stock Purchases may be
granted; (ii) determine the time or times at which Options may be granted or Restricted Stock Purchases made; (iii) determine the exercise price of shares subject to each Option, which price shall not be less than the minimum price
specified in paragraph 6, and the purchase price of shares subject to each Restricted Stock Purchase, which price shall be not less than 85% of the fair market value of shares of common stock on the date of the grant of the right to make a
Restricted Stock Purchase; (iv) determine whether each Option granted shall be an ISO or a Non-Qualified Option; (v) determine (subject to paragraph 7) the time or times when each Option shall become exercisable and the duration of the
exercise period; (vi) determine whether restrictions such as repurchase options are to be imposed on shares subject to Options and Restricted Stock Purchases and the nature of any such restrictions; (vii) impose such other terms and
conditions with respect to Stock Rights not inconsistent with

 the terms of this Plan as it deems necessary or desirable; and (viii) interpret the Plan and prescribe and rescind rules and regulations relating to it. 

                If the Committee decides to issue a Non-Qualified Option, the Committee shall take whatever
actions it deems necessary, under the Code and the regulations promulgated thereunder, to ensure that such Option is not treated as an ISO. The interpretation and construction by the Committee of any provisions of the Plan or of any Stock Right
granted under it shall be final unless otherwise determined by the Board. The Committee may from time to time adopt such rules and regulations for carrying out the Plan as it may deem best. No member of the Board or the Committee shall be liable for
any action or determination made in good faith with respect to the Plan or any Stock Right granted under it.

                C.     Committee Actions.   The Committee may select one of
its members as its chairman and shall hold meetings at such time and places as it may determine. Acts by a majority of the Committee, acting at a meeting (whether held in person or by teleconference), or acts reduced to or approved in writing by all
of the members of the Committee, shall be the valid acts of the Committee. From time to time the Board may increase the size of the Committee and appoint additional members thereof, remove members (with or without cause) and appoint new members in
substitution therefor, fill vacancies however caused, or remove all members of the Committee and thereafter directly administer the Plan, subject to compliance with paragraph 2A.

                D.     Grant of Stock Rights to Board Members.   Stock Rights
may be granted to members of the Board, subject to compliance with Rule 16b-3 when required by paragraph 2A. All grants of Stock Rights to members of the Board shall be made in all respects in accordance with the provisions of this Plan applicable
to other eligible persons.

                3.       Eligible Employees and Others.   ISOs may be
granted to any employee of the Company or any Related Corporation. Those officers and directors of the Company who are not employees may not be granted ISOs under the Plan. Non-Qualified Options and authorizations to make Restricted Stock Purchases
may be granted to any employee, officer or director (whether or not also an employee) or consultant or advisor of the Company or any Related Corporation. The Committee may take into consideration a recipient's individual circumstances in determining
whether to grant a Stock Right. Granting a Stock Right to any individual or entity shall neither entitle that individual or entity to, nor disqualify him from, participation in any other grant of Stock Rights.

                4.      Common Stock.   The stock subject to Stock
Rights shall be authorized but unissued shares of Common Stock of the Company, $.001 par value (the "Common Stock"), or shares of Common Stock reacquired by the Company in any manner. The aggregate number of shares which may be issued
pursuant to the Plan is 7,000,000 (giving effect to a 2.6 for one stock split effected in July, 2000) minus that number of shares which are the subject of option grants made, or were purchased pursuant to the exercise of options that were granted,
to employees, officers directors, or consultants of the Company or Related Corporations prior to the date of the adoption of this plan by the Company's Board of Directors, subject to adjustment as provided in paragraph 13. Any such shares may be
issued pursuant to the exercise of ISOs or Non-Qualified Options or pursuant to Restricted Stock Purchases, so long as the aggregate number of shares so issued does not exceed such number, as adjusted. Until such time as the Company becomes subject
to Section 162(m) of the Code with respect to compensation earned under this Plan, if any Stock Right granted under the Plan shall expire or terminate for any reason without having been exercised in full or shall cease for any reason to be
exercisable in whole or in part or if any shares of Common Stock issued pursuant to a Stock Right have been repurchased by the Company in accordance with the terms of the agreement or instrument pursuant to which the Stock Right is granted, then the
unpurchased shares subject to such Stock Right and any shares issued pursuant to a Stock Right that have been so repurchased by the Company (or shares in substitution thereof) shall again be available for grants of Stock Right under the
Plan.

                5.     Granting of Stock Rights.   Stock Rights may be
granted under the Plan at any time after January 24, 2000 and prior to January 24, 2010. The date of grant of a Stock Right under the Plan will be the date specified by the Committee at the time it grants the Stock Right; provided, however, that
such date shall not be prior to the date on which the Committee acts to approve the grant. The Committee shall have the right, with the consent of the optionee, to convert an ISO granted under the Plan to a Non-Qualified Option pursuant to paragraph
17.

                6.     Minimum Option Price; ISO Limitations.

                A.    Price for ISOs.   The exercise price per share
specified in the agreement relating to each ISO granted under the Plan shall not be less than the fair market value per share of Common Stock on the date of such grant. In the case of an ISO to be granted to an employee owning stock possessing more
than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Related Corporation, the price per share specified in the agreement relating to such ISO shall not be less than one hundred ten percent (110%) of
the fair market value per share of Common Stock on the date of grant.

                B.     $100,000 Annual Limitation on ISOs.   Each eligible
employee may be granted ISOs only to the extent that, in the aggregate under this Plan and all other incentive stock option plans of the Company and any Related Corporation, such ISOs do not become exercisable for the first time by such employee
during any calendar year in a manner which would entitle the employee to purchase more than $100,000 in fair market value (determined at the time the ISOs were granted) of Common Stock in that year. Any Options granted to an employee in excess of
such amount will be granted as Non-Qualified Options.

                C.     Determination of Fair Market Value.   If, at the time
an Option is granted under the Plan, the Company's Common Stock is publicly traded, "fair market value" shall be determined as of the last business day for which the prices or quotes discussed in this sentence are available prior to the
date such Option is granted and shall mean (i) the average (on that date) of the high and low prices of the Common Stock on the principal national securities exchange on which the Common Stock is traded, if the Common Stock is then traded on a
national securities exchange, or on the Nasdaq National Market or the NASDAQ Small Cap Market, if the Common Stock is not then traded on a national securities exchange; or (ii) the average of the low bid and high ask prices as quoted on that
date by an established quotation service for over-the-counter securities, if the Common Stock is not then traded on a national securities exchange or the NASDAQ National Market or the NASDAQ Small Cap Market. If the Common Stock is not publicly
traded at the time an Option is granted under the Plan, "fair market value" shall be deemed to be the fair value of the Common Stock as determined by the Committee after taking into consideration all factors in good faith it deems
appropriate, including, without limitation, recent sale and offer prices of the Common Stock in private transactions negotiated at arm's length, if any.

                7.      Option Duration.   Subject to earlier termination as
provided in paragraphs 9, 10, and 13B, each Option shall expire on the date specified by the Committee and set forth in the original stock option agreement granting such Option, provided that ISOs shall in any event expire not more than ten years
from the date of grant and ISOs granted to an employee owning stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Related Corporation, such ISOs shall expire not more than
five years from the date of grant. Non-Qualified Options shall expire on the date specified in the agreement granting such Non-Qualified Options, subject to extension as determined by the Committee. ISOs, or any part thereof, that have been
converted into Non-Qualified Options may be extended as provided in paragraph 17.

                8.      Exercise of Option.   Subject to the provisions of
paragraphs 9 through 13, each Option granted under the Plan shall be exercisable as follows:

                A.     Vesting.   Unless otherwise specified by the Committee or
the Board of Directors and subject to paragraphs 9 and 10 with respect to ISO's, Options granted to employees shall vest on a schedule at least as rapid as the following: (a) as to 25% of the shares subject to the Option, on the first
anniversary 

of the date of grant of the Option; and (b) as to the remaining 75% of the shares subject to the Option, in 12 equal quarterly installments beginning one calendar quarter after the date of
such anniversary. The Committee may also specify such other conditions precedent as it deems appropriate to the exercise of an Option.

                B.      Full Vesting of Installments.   Once an installment
becomes exercisable it shall remain exercisable until expiration or termination of the Option, unless otherwise specified by the Committee.

                C.      Partial Exercise.   Each Option or installment may be
exercised at any time or from time to time, in whole or in part, for up to the total number of shares with respect to which it is then exercisable, provided that the Committee may specify a certain minimum number or percentage of the shares issuable
upon exercise of any Option that must be purchased upon any exercise.

                D.      Acceleration of Vesting.   The Committee shall have
the right to accelerate the date of exercise of any installment of any Option, despite the fact that such acceleration may: (i) cause the application of Sections 280G and 4999 of the Code if an Acquisition, as defined below in paragraph
13B, occurs, or (ii) disqualify all or part of the Option as an ISO.

                9.      Termination of Employment.   If an ISO optionee
ceases to be employed by the Company and all Related Corporations other than by reason of death or disability as defined in paragraph 10, no further installments of his ISOs shall become exercisable following the date of such cessation of
employment, and his ISOs shall terminate after the passage of ninety (90) days from the date of termination of his employment, but in no event later than on their specified expiration dates, except to the extent that such ISOs (or unexercised
installments thereof) have been converted into Non-Qualified Options pursuant to paragraph 17. Nothing in the Plan shall be deemed to give any grantee of any Stock Right the right to be retained in employment or other service by the Company or any
Related Corporation for any period of time.

                The Board or Committee may establish such provisions in particular Stock Right grant
agreements as it may deem appropriate with respect to the treatment of Stock Rights other than ISOs upon the termination of the employment of the holder of the Stock Right.

                10.     Death; Disability.

                A.      Death.   If an ISO optionee ceases to be employed by
the Company and all Related Corporations by reason of his death, any ISO of his may be exercised, to the extent of the number of shares with respect to which he could have exercised it on the date of his death, by his estate, personal representative
or beneficiary who has acquired the ISO by will or by the laws of descent and distribution, at any time prior to the earlier of the specified expiration date of the ISO or one hundred and eighty (180) days from the date of such optionee's
death.

                B.     Disability.   If an ISO optionee ceases to be
employed by the Company and all Related Corporations by reason of his disability, he or, in the event of his death, his estate, personal representative or beneficiary who has acquired the ISO by will or by the laws of descent and distribution, shall
have the right to exercise any ISO held by him on the date of termination of employment, to the extent of the number of shares with respect to which he could have exercised it on that date, at any time prior to the earlier of the specified
expiration date of the ISO or one (1) year from the date of the termination of the optionee's employment. For the purposes of the Plan, the term "disability" shall mean "permanent and total disability" as defined in Section
22(e)(3) of the Code or successor statute.

                11.     Assignability.   No ISO, and unless specified in the
agreement or instrument pursuant to which the Option is granted, no Non-Qualified Option shall be assignable or transferable by the optionee except by will or by the laws of descent and distribution, and during the lifetime of the grantee each Stock
Right shall be exercisable only by him or her. No Stock Right, and no right to exercise any portion thereof, shall be subject to execution, attachment, or similar process, assignment, or any other alienation or 

hypothecation. Upon any attempt so to transfer, assign, pledge, hypothecate, or otherwise dispose of any Stock Right, or of any right or privilege conferred thereby, contrary to the provisions
thereof or hereof or upon the levy of any attachment or similar process upon any Stock Right, right or privilege, such Stock Right and such rights and privileges shall immediately become null and void.

                12.     Terms and Conditions of Stock Rights.   Stock Rights
shall be evidenced by instruments (which need not be identical) in such forms as the Committee may from time to time approve. Such instruments shall conform to the terms and conditions set forth in paragraphs 6 through 11 hereof to the extent
applicable and may contain such other provisions as the Committee deems advisable which are not inconsistent with the Plan. Without limiting the foregoing, such provisions may include transfer restrictions, rights of refusal, vesting provisions,
repurchase rights and drag-along rights with respect to shares of Common Stock issuable upon exercise of Stock Rights, and such other restrictions applicable to shares of Common Stock issuable upon exercise of Stock Rights as the Committee may deem
appropriate. In granting any Non-Qualified Option, the Committee may specify that such Non-Qualified Option shall be subject to the restrictions set forth herein with respect to ISOs, or to such other termination, cancellation or other provisions as
the Committee may determine. The Committee may from time to time confer authority and responsibility on one or more of its own members and/or one or more officers of the Company to execute and deliver such instruments. The proper officers of the
Company are authorized and directed to take any and all action necessary or advisable from time to time to carry out the terms of such instruments.

                13.      Adjustments.   Upon the occurrence of any of the
following events, an optionee's rights with respect to Options granted to him hereunder shall be adjusted as hereinafter provided, unless otherwise specifically provided in the written agreement between the optionee and the Company relating to such
Option:

                A.       Stock Dividends and Stock Splits.   If the
shares of Common Stock shall be subdivided or combined into a greater or smaller number of shares or if the Company shall issue any shares of Common Stock as a stock dividend on its outstanding Common Stock, the number of shares of Common Stock
deliverable upon the exercise of Options shall be appropriately increased or decreased proportionately, and appropriate adjustments shall be made in the purchase price per share to reflect such subdivision, combination or stock dividend.

                B.        Consolidations, Mergers or Sales of Assets or Stock.
  If the Company is to be consolidated with or acquired by another person or entity in a merger, sale of all or substantially all of the Company's assets or stock or otherwise (an "Acquisition"), the Committee or the board of
directors of any entity assuming the obligations of the Company hereunder (the "Successor Board") shall, with respect to outstanding Options or shares acquired upon exercise of any Option, take one or more of the following actions: (i)
make appropriate provision for the continuation of such options by substituting on an equitable basis for the shares then subject to such Options the consideration payable with respect to the outstanding shares of Common Stock in connection with the
Acquisition; (ii) accelerate the date of exercise of such Options or of any installment of any such Options; (iii) upon written notice to the optionees, provide that all Options must be exercised, to the extent then exercisable, within a specified
number of days of the date of such notice, at the end of which period the Options, including those which are not then exercisable, shall terminate; (iv) terminate all Options in exchange for a cash payment equal to the excess of the fair market
value of the shares subject to such Options (to the extent then exercisable) over the exercise price thereof; or (v) in the event of a stock sale, require that the optionee sell to the purchaser to whom such stock sale is to be made, all shares
previously issued to such optionee upon exercise of any Option, at a price equal to the portion of the net consideration from such sale which is attributable to such shares. Nothing contained herein will be deemed to require the Company to take, or
refrain from taking, any one or more of the foregoing actions.

                C.       Recapitalization or Reorganization.   In the
event of a recapitalization or reorganization of the Company (other than a transaction described in subparagraph B above) pursuant to which securities of the Company or of another corporation are issued with respect to the outstanding shares of
Common Stock, an optionee upon exercising an Option shall be entitled to receive for the purchase price paid upon such 

exercise the securities he would have received if he had exercised his Option prior to such recapitalization or reorganization and had been the owner of the Common Stock receivable upon such
exercise at such time.

                D.     Modification of ISOs.   Notwithstanding the foregoing,
any adjustments made pursuant to the foregoing subparagraphs A, B or C with respect to ISOs shall be made only after the Committee, after consulting with counsel for the Company, determines whether such adjustments would constitute a
"modification" of such ISOs (as that term is defined in Section 424 of the Code or any successor thereto) or would cause any adverse tax consequences for the holders of such ISOs. If the Committee determines that such adjustments made with
respect to ISOs would constitute a modification of such ISOs, it may refrain from making such adjustments.

                E.      Issuances of Securities and Non-Stock Dividends.  
 Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares subject to Options. No adjustments shall be made for dividends paid in cash or in property other than securities of the Company (and, in the case of securities of the Company, such adjustments shall be made pursuant to the
foregoing subparagraph A).

                F.     Fractional Shares.   No fractional shares shall be
issued under the Plan, and the optionee shall receive from the Company cash in lieu of such fractional shares.

                G.     Adjustments.   Upon the happening of any of the
foregoing events described in subparagraphs A, B or C above, the class and aggregate number of shares set forth in paragraph 4 hereof that are subject to Stock Rights which previously have been or subsequently may be granted under the Plan shall
also be appropriately adjusted to reflect the events described in such subparagraphs. The Committee or the Successor Board, as applicable, shall determine the specific adjustments to be made under this paragraph 13 and its determination shall be
conclusive.

                If any person or entity owning Common Stock obtained by exercise of a Stock Right made hereunder
receives shares or securities or cash in connection with a corporate transaction described in subparagraphs A, B or C above as a result of owning such Common Stock, except as otherwise provided in subparagraph B, such shares or securities or cash
shall be subject to all of the conditions and restrictions applicable to the Common Stock with respect to which such shares or securities or cash were issued, unless otherwise determined by the Committee or the Board of Directors of the Surviving
Entity.

                H.     Pooling-of-Interests Accounting.   If the Company
proposes to engage in an Acquisition intended to be accounted for as a pooling-of-interests, and in the event that the provisions of this Plan or of any agreement hereunder, or any actions of the Board taken in connection with such Acquisition, are
determined by the Company's or the Surviving Entity's independent public accountants to cause such Acquisition to fail to be accounted for as a pooling-of-interests, then such provisions or actions may be amended or rescinded at the election of the
Committee, without the consent of any grantee, to be consistent with pooling-of-interests accounting treatment for such Acquisition.

                14.     Means of Exercising Stock Rights.   A Stock Right (or
any part or installment thereof) shall be exercised by the holder thereof giving written notice to the Company at its principal office address. Such notice shall identify the Stock Right being exercised and specify the number of shares as to which
such Stock Right is being exercised, accompanied by full payment of the purchase price therefor either (a) in United States dollars in cash or by check, or (b) at the discretion of the Committee, delivery of an irrevocable and unconditional
undertaking, satisfactory in form and substance to the Company, by a creditworthy broker to deliver promptly to the Company sufficient funds to pay the exercise price, or delivery to the Company of a copy of irrevocable and unconditional
instructions, satisfactory in form and substance to the Company, to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to pay the exercise price, or (c) at the discretion of the Committee, through delivery of shares
of Common Stock having a fair market value equal as of the date of the exercise to the cash exercise price of

 the Stock Right, or (d) at the discretion of the Committee, by delivery of the grantee's personal recourse note bearing interest payable not less than annually at no less than 100% of the
applicable Federal rate, as defined in Section 1274(d) of the Code, or (e) at the discretion of the Committee, by any combination of (a), (b) (c) and (d) above. The holder of a Stock Right shall not have the rights of a shareholder with respect to
the shares covered by his Stock Right until the date of issuance of a stock certificate to him for the shares subject to the Stock Right. Except as expressly provided above in paragraph 13 with respect to changes in capitalization and stock
dividends, no adjustment shall be made for dividends or similar rights for which the record date is before the date such stock certificate is issued.

                15.     Term and Amendment of Plan. This Plan was originally adopted by
the Board on January 24, 2000 and approved by the stockholders of the Company on July 5, 2000. The Plan was amended by the Directors of the Company on January 15, 2001 and in March 2001 (the "Amendments"). The Amendments (which increase
the authorized number of shares under the Plan) will be presented to the stockholders of the Company for approval on or prior to January 15, 2002. If the approval of stockholders is not obtained by such date, ISOs granted under the Plan after the
date of the foregoing Director's approval of the Amendments will be converted automatically to Non-Qualified Options, without any action on the part of the Board, the Committee, or the holder of the Option. The Plan shall expire on that date which
is ten years from the date of its adoption by the Board (except as to Options outstanding on the expiration date). Options may be granted under the Plan prior to the date of stockholder approval of the Plan. 

                The Board may terminate or amend the Plan in any respect at any time, except that, without the
approval of the stockholders obtained within 12 months before or after the Board adopts a resolution authorizing any of the following actions: (a) the total number of shares that may be issued under the Plan may not be increased (except by
adjustment pursuant to paragraph 13); (b) the provisions of paragraph 3 regarding eligibility for grants of ISOs may not be modified; (c) the provisions of paragraph 6(B) regarding the exercise price at which shares may be offered pursuant to ISOs
may not be modified (except by adjustment pursuant to paragraph 13); and (d) the expiration date of the Plan may not be extended. 

                16.      Section 162(m)   Notwithstanding anything herein to
the contrary, no Stock Right shall become exercisable, vested or realizable if such Stock Right is granted to an employee that is a "covered employee" as defined in Section 162(m) of the Code and the Committee has determined that such
Stock Right should be structured so that it is not "applicable employee remuneration" under such Section 162(m) unless and until the terms of this Plan, including any amendment hereto, have been approved by the Company's stockholders in
the manner and to the extent required under such Section 162(m).

                17.     Amendment of Stock Rights.   The Board or Committee
may amend, modify or terminate any outstanding Stock Rights including, but not limited to, substituting therefor another Stock Right of the same or a different type, changing the date of exercise or realization, and converting an ISO to a
Non-Qualified Option; provided that, except as otherwise provided in paragraphs 9, 10, and 15, the grantee's consent to such action shall be required unless the Board or Committee determines that the action, taking into account any
related action, would not materially and adversely affect the grantee.

                18.      Application Of Funds.   The proceeds received by the
Company from the exercise of Options granted and Restricted Stock Purchases authorized under the Plan shall be used for general corporate purposes.

                19.      Governmental Regulation.   The Company's obligation
to sell and deliver shares of the Common Stock under this Plan is subject to the approval of any governmental authority required in connection with the authorization, issuance or sale of such shares.

                20.     Withholding of Additional Income Taxes.   Upon the
exercise of a Non-Qualified Option, the making of a Restricted Stock Purchase for less than its fair market value, the making of a Disqualifying Disposition (as defined in paragraph 21) or the vesting of forfeitable stock purchased pursuant to a
Restricted Stock Purchase, the Company, in accordance with Section 3402(a) of the Code, may require the 

holder of the Stock Right to pay additional withholding taxes in respect of the amount that is considered compensation includible in such person's gross income. The Committee in its discretion
may condition (i) the exercise of an Option, (ii) a the making of a Restricted Stock Purchase Award, or (iii) the vesting of forfeitable stock purchased pursuant to a Restricted Stock Purchase, on the grantee's payment of such
additional withholding taxes.

                21.     Notice to Company of Disqualifying Disposition.  
 Each employee who receives an ISO must agree to notify the Company in writing immediately after the employee makes a Disqualifying Disposition of any Common Stock acquired pursuant to the exercise of an ISO. A "Disqualifying
Disposition" is any disposition (including any sale) of such Common Stock before the later of:

                       A.         two
years after the date the employee was granted the ISO, and

                       B.         one
year after the date the employee acquired Common Stock by exercising the ISO. If the employee has died before such stock is sold, these holding period requirements do not apply and no Disqualifying Disposition can occur thereafter.

SECTION 2.        PIGGYBACK REGISTRATION.

         If the Corporation, at any time during which Registrable Shares are

Securities Act (other than a registration on Form S-4 or S-8 (or similar or
successor forms) or relating solely to the sale of securities to participants in
a Corporation stock plan or a transaction covered by Rule 145 under the
Securities Act, a registration in which the only stock being registered is
Common Stock issuable upon conversion of debt securities which are also being
registered, or any registration on any form which does not include substantially
the same information as would be required to be included in a registration
statement covering the sale of the Registrable Securities (collectively,

                                      -2-
<PAGE>   4
"Non-Covered Registrations")), it shall give written notice to all the
Stockholders of its intention to so register such Common Stock at least thirty
(30) days before the initial filing of the Registration Statement therefor. Upon
the written request of any Stockholder delivered to the Corporation within
thirty (30) days after delivery of any such notice by the Corporation,
specifying the number of Registrable Shares proposed to be included in such
registration and stating that such Stockholder desires to sell such Registrable
Shares, the Corporation shall use its best efforts to cause all such Registrable
Shares to be included in such registration on the same terms and conditions as
the securities otherwise being sold in such registration; provided, however,
that if the registration is for a firm commitment underwritten offering and the
managing underwriter advises the Corporation and such Shareholders in writing
that the inclusion of all such Registrable Shares would interfere with the
successful marketing (including pricing) of the shares proposed to be included
in the registration by other parties (including, without limitation, the
Corporation), then the number of Registrable Shares and other shares of Common
Stock to be included in such registration (other than shares to be registered
and sold by the Corporation for its own account) shall be reduced pro rata in
accordance with the respective numbers of shares proposed to be registered and
sold by the respective holders thereof (with the holders of other shares of
Common Stock to be included in such registration being reduced in accordance
with the terms and conditions of their respective registration rights
agreement). If the Stockholders are so limited, however, Registrable Shares may
not, without the requesting Stockholder's consent, in any event be reduced below
eight percent (8%) of the total amount of securities included in such offering.

SECTION 3.        REGISTRATION PROCEDURES.

         If and whenever the Corporation is under an obligation pursuant to the
provisions of this Agreement to use its best efforts to effect the registration
of any Registrable Shares, the Corporation shall, as expeditiously as
practicable:

         (a) use its best efforts to prepare and file a Registration Statement
that registers such Registrable Shares and to cause such Registration Statement
to become and remain effective for a period of two (2) years or (if earlier)
until all of such Registrable Shares have been disposed of or such shares
otherwise cease (other than due to the effectiveness of such Registration
Statement) to be Registrable Shares;

         (b) furnish (at least five business days before filing with respect to
the original filing and one business day with respect to the filing of any
amendments, supplements or Rule 424 prospectuses) a Registration Statement that
registers such Registrable Shares, a prospectus relating thereto and any
amendments or supplements relating to such Registration Statement or prospectus,
to one counsel selected by the participating Stockholders (the "STOCKHOLDERS'
COUNSEL"), copies of all such documents proposed to be filed (it being
understood that such business-day periods need not apply to successive drafts of
the same document proposed to be filed so long as such successive drafts are
supplied to the Stockholders' Counsel in advance of the proposed filing by a
period of time that is customary and reasonable under the circumstances);

                                      -3-
<PAGE>   5
         (c) prepare and file with the Commission such amendments and
supplements to such Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective for
at least a period of two (2) years or (if earlier) until all of such Registrable
Shares have been disposed of or such shares otherwise cease to be Registrable
Shares and to comply with the provisions of the Securities Act with respect to
the sale or other disposition of such Registrable Shares;

         (d) notify Stockholders' Counsel in writing (i) of the receipt by the
Corporation of any notification with respect to any comments by the Commission
with respect to such Registration Statement or prospectus or any amendment or
supplement thereto, or any request by the Commission for the amending or
supplementing thereof or for additional information with respect thereto, (ii)
of the receipt by the Corporation of any notification with respect to the
issuance by the Commission of any stop order suspending the effectiveness of
such Registration Statement or prospectus or any amendment or supplement
thereto, or the initiation or threatening of any proceeding for that purpose,
and (iii) of the receipt by the Corporation of any notification with respect to
the suspension of the qualification of such Registrable Shares for sale in any
jurisdiction, or the initiation or threatening of any proceeding for such
purposes;

         (e) without limiting subsection (d) above, use its best efforts to
cause such Registrable Shares to be registered with or approved by such other
United States federal and state governmental agencies or authorities as may be
necessary by virtue of the business and operations of the Corporation to enable
the Stockholders holding such Registrable Shares to consummate the disposition
of such Registrable Shares in the intended manner;

         (f) notify the Stockholders holding such Registrable Shares on a timely
basis, at any time when a prospectus relating to such Registrable Shares is
required to be delivered under the Securities Act within the appropriate period
mentioned in subparagraph (a) of this Section 4, of the happening of any event
as a result of which the prospectus included in such Registration Statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then existing
and, at the request of the Stockholders, prepare and furnish to such
Stockholders a reasonable number of copies of a supplement to or an amendment of
such prospectus as may be necessary so that, as thereafter delivered to the
offerees of such shares, such prospectus shall not include an untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading in light of
the circumstances then existing;

         (g) subject to the execution of confidentiality agreements in form and
substance reasonably satisfactory to the Corporation, make available upon
reasonable notice and during normal business hours, for inspection by the
Stockholders holding such Registrable Shares, any underwriter participating in
any disposition pursuant to such Registration Statement and any attorney,
accountant or other agent retained by the Stockholders or underwriter
(collectively, the "INSPECTORS"), all pertinent financial and other records,
pertinent corporate documents and properties of the Corporation (collectively,
the "RECORDS"), as shall be reasonably necessary to

                                      -4-
<PAGE>   6
enable them to exercise their due diligence responsibility, and cause the
Corporation's officers, directors and employees to supply all information
(together with the Records, the "INFORMATION") reasonably requested by any such
Inspector in connection with such Registration Statement. Any of the Information
which the Corporation determines in good faith to be confidential, and of which
determination the Inspectors are so notified, shall not be disclosed by the
Inspectors unless (i) the disclosure of such Information is necessary to avoid
or correct a misstatement or omission in the Registration Statement or related
prospectus, (ii) the release of such Information is ordered pursuant to a
subpoena or other order from a court or other regulatory authority of competent
jurisdiction, or (iii) such Information has been made generally available to the
public;

         (h) use its best efforts to obtain from its independent certified
public accountants "cold comfort" letters in customary form and at customary
times and covering matters of the type customarily covered by cold comfort
letters;

         (i) use its best efforts to obtain from its counsel an opinion or
opinions in customary form;

         (j) provide a transfer agent and registrar (which may be the same
entity) for such Registrable Shares;

         (k) use its best efforts to list such Registrable Shares on the Nasdaq
National Market or any United States national securities exchange on which any
shares of the Common Stock are listed or, if the Common Stock is not so listed,
use its best efforts to qualify such Registrable Shares for listing or quotation
on such other securities exchange as the holders of a majority of such
Registrable Shares shall reasonably request;

         (l) otherwise use its best efforts to comply with all applicable rules
and regulations of the Commission and make available to its security holders, as
soon as reasonably practicable, earnings statements (which need not be audited)
covering a period of twelve (12) months beginning within three months after the
effective date of the Registration Statement, which earnings statements shall
satisfy the provisions of Section 11(a) of the Securities Act; and

         (m) subject to all the other provisions of this Agreement, use its best
efforts to take all other steps necessary to effect the registration of such
Registrable Shares contemplated hereby.

         Each holder of the Registrable Shares, upon receipt of any notice from
the Corporation of any event of the kind described in (f) hereof, shall
forthwith discontinue disposition of the Registrable Shares pursuant to the
Registration Statement covering such Registrable Shares until such holder's
receipt of the copies of the supplemented or amended prospectus contemplated by
(f) hereof, and, if so directed by the Corporation, such holder shall deliver to
the Corporation all copies, other than permanent file copies then in such
holder's possession, of the prospectus covering such Registrable Shares at the
time of receipt of such notice. The Corporation may delay or suspend the
effectiveness of any Registration Statement, for a period of up to ninety (90)
consecutive days, if it gives written notice to the Stockholders, at the time of
such request, that (A) the Corporation is engaged, or has fixed plans to engage
within ninety (90) days (evidenced

                                      -5-
<PAGE>   7
by the Board of Directors having deliberated on and approved such plans), in a
firm commitment underwritten public offering of Common Stock in which
Stockholders may include Registrable Shares pursuant to Section 2, or (B) such
registration would materially and adversely interfere with a material
transaction involving the Corporation that has been approved by the Board of
Directors.

SECTION 4.        EXPENSES.

         All expenses (other than stock transfer fees (including, without
limitation, the cost of all transfer tax stamps), underwriting discounts and
commissions and similar fees relating to the distribution of the Registrable
Shares) incurred by the Corporation in complying with Section 3, including,
without limitation, all registration and filing fees (including all expenses
incident to filing with the National Association of Securities Dealers, Inc.),
fees and expenses of complying with United States state securities and blue sky
laws, printing expenses, fees and expenses of the Corporation's counsel and
accountants, and reasonable fees and expenses of the Stockholders' Counsel,
shall be paid by the Corporation.

SECTION 5.        INDEMNIFICATION.

         (a) In connection with any registration of any Registrable Shares under
the Securities Act pursuant to this Agreement, the Corporation shall indemnify
and hold harmless the holders of Registrable Shares, each underwriter, broker or
any other person acting on behalf of the holders of Registrable Shares, and each
other person, if any, who controls any of the foregoing persons within the
meaning of the Securities Act (each a "CORPORATION INDEMNIFIED PERSON") against
any losses, claims, damages or liabilities, joint or several (or actions in
respect thereof), to which any of the foregoing persons may become subject under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) (i) arise out of or are based upon
an untrue statement or allegedly untrue statement of a material fact contained
in the Registration Statement under which such Registrable Shares were
registered under the Securities Act, any preliminary prospectus or final
prospectus contained therein or otherwise filed with the Commission, any
amendment or supplement thereto or any document incident to registration or
qualification of any Registrable Shares, or (ii) arise out of or are based upon
the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading or,
with respect to any prospectus, necessary to make the statements therein in
light of the circumstances under which they were made not misleading, or any
violation by the Corporation of the Securities Act or state securities or blue
sky laws applicable to the Corporation and relating to action or inaction
required of the Corporation in connection with such registration or
qualification under such state securities or blue sky laws; and shall reimburse
each Corporation Indemnified Person for any legal or other expenses reasonably
incurred in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Corporation shall not
be liable in any such case to the extent that any such loss, claim, damage,
liability or action (including any legal or other expenses incurred) arises out
of or is based upon an untrue statement or allegedly untrue statement or
omission or alleged omission made in said Registration Statement, preliminary

                                      -6-
<PAGE>   8
prospectus, final prospectus, amendment, supplement or document incident to
registration or qualification of any Registrable Shares in reliance upon and in
conformity with written information furnished by such holder of Registrable
Shares or their counsel to the Corporation or such underwriter specifically for
use in connection with the preparation of such Registration Statement,
preliminary prospectus, final prospectus, amendment, supplement or document;
provided further, however, that the foregoing indemnity agreement is subject to
the condition that, insofar as it relates to any untrue statement, alleged
untrue statement, omission or alleged omission made in any preliminary
prospectus that was eliminated or remedied in the final prospectus (filed
pursuant to Rule 424 of the Securities Act or otherwise), such indemnity
agreement shall not inure to the benefit of any Stockholder, underwriter, broker
or other person acting on behalf of holders of the Registrable Shares from whom
the person asserting any loss, claim, damage, liability or expense purchased the
Registrable Shares which are the subject thereof, if a copy of such final
prospectus had been made available to such Stockholder, underwriter, broker or
other person acting on behalf of holders of the Registrable Shares and such
final prospectus was not delivered to such asserting person with or prior to the
written confirmation of the sale of such Registrable Shares to such asserting
person.

         (b) In connection with any registration of Registrable Shares under the
Securities Act pursuant to this Agreement, each holder of Registrable Shares
including such Registrable Shares in such registration shall severally, and not
jointly, indemnify and hold harmless (in the same manner and to the same extent
as set forth in the preceding paragraph of this Section 5) the Corporation, each
director of the Corporation, each officer of the Corporation who shall sign such
Registration Statement, each person acting on behalf of the Corporation, each
underwriter, broker or other person acting on behalf of the holders of
Registrable Shares, and each person who controls any of the foregoing persons
within the meaning of the Securities Act with respect to any statement in such
Registration Statement, any preliminary prospectus or final prospectus contained
therein or otherwise filed with the Commission, any amendment or supplement
thereto or any document incident to registration or qualification of any
Registrable Shares, if such statement was made in reliance upon and in
conformity with written information furnished by such holder of Registrable
Shares or their counsel to the Corporation or such underwriter specifically for
use in connection with the preparation of such Registration Statement,
preliminary prospectus, final prospectus, amendment, supplement or document;
provided, however, that the maximum amount of liability in respect of such
indemnification shall be limited, in the case of each seller of Registrable
Shares, to an amount equal to the net proceeds actually received by such seller
from the sale of Registrable Shares effected pursuant to such registration.

         (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action involving a claim referred to in the preceding
paragraphs of this Section 5, such indemnified party will, if a claim in respect
thereof is made against an indemnifying party, give written notice to the latter
of the commencement of such action. The failure of any indemnified party to
notify an indemnifying party of any such action shall not (except to the extent
such failure shall have a material adverse effect on the indemnifying party)
relieve the indemnifying party from any liability in respect of such action that
it may have to such indemnified party on

                                      -7-
<PAGE>   9
account of this Section 5. In case any such action is brought against an
indemnified party, the indemnifying party will be entitled to participate in and
to assume the defense thereof, jointly with any other indemnifying party
similarly notified to the extent that it may wish, with counsel reasonably
satisfactory to such indemnified party, and after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party shall not be responsible for any legal expenses
subsequently incurred by the indemnified party in connection with the defense
thereof; provided, however, that if any indemnified party shall have reasonably
concluded that there may be one or more legal or equitable defenses available to
such indemnified party which are in addition to or conflict with those available
to the indemnifying party, or that such claim or litigation involves or could
have an effect upon matters beyond the scope of the indemnity agreement provided
in this Section 5, the indemnifying party shall not have the right to assume the
defense of such action on behalf of such indemnified party (but shall have the
right to participate therein with counsel of its choice), and such indemnifying
party shall reimburse such indemnified party and any person controlling such
indemnified party for that portion of the fees and expenses of any counsel
retained by the indemnified party which are reasonably related to the matters
covered by the indemnity agreement provided in this Section 5. If the
indemnifying party is not entitled to, or elects not to, assume the defense of a
claim, it will not be obligated to pay the fees and expenses of more than one
counsel for similarly situated indemnified parties with respect to such claim.

         (d) If the indemnification provided for in this Section 5 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, claim, damage, liability or action referred to herein, then
the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amounts paid or payable by such indemnified
party as a result of such loss, claim, damage, liability or action in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements, omissions or actions which resulted in such loss, claim,
damage, liability or action as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether an untrue or alleged untrue statement of a material fact or an omission
or alleged omission to state a material fact relates to information supplied by
the indemnifying party or by the indemnified party and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
any such statement or omission or any other action upon which the loss, claim,
damage, liability or action is based. The parties agree that it would not be
just and equitable if contribution pursuant hereto were determined by pro rata
allocation or by any other method or allocation which does not take account of
the equitable considerations referred to herein. No person guilty of fraudulent
misrepresentation shall be entitled to contribution from any person.

SECTION 6.        UNDERWRITING AGREEMENT.

         Notwithstanding the provisions of Section 3, Section 4 and Section 5,
to the extent that any Stockholders selling Registrable Shares shall enter into
an underwriting or similar agreement, which agreement contains provisions
covering one or more issues addressed in such

                                      -8-
<PAGE>   10
Sections, the provisions contained in such agreement addressing such issue or
issues shall control as to such Stockholders.

SECTION 7.        OBLIGATIONS OF STOCKHOLDERS.

         The Corporation's obligations under this Agreement to a Stockholder
shall be conditioned upon such Stockholder's compliance with the following:

         (a) such Stockholder shall cooperate with the Corporation in connection
with the preparation of the Registration Statement, and for so long as the
Corporation is obligated to keep the Registration Statement effective, such
Stockholder will provide to the Corporation, in writing, for use in the
Registration Statement, such information regarding such Stockholder and the
Registrable Shares held by such Stockholder as shall be required to effect the
registration of such Stockholder's Registrable Shares and to maintain the
currency and effectiveness thereof;

         (b) if such Stockholder's Registrable Shares are being included in an
underwritten public offering, such Stockholder shall enter into such agreements
with the Corporation and with the underwriters containing representations,
warranties, indemnities and agreements as are in each case customarily entered
into and made by selling stockholders, and will cause its counsel to give any
legal opinions customarily given, in secondary distributions under similar
circumstances;

         (c) during such time as such Stockholder may be engaged in a
distribution of the Registrable Shares, such Stockholder will comply with all
applicable securities laws;

         (d) other than in the case of an underwritten public offering, such
Stockholder will advise the Corporation in writing of the dates on which such
Stockholder sold shares, the number of such shares sold, the terms and the
manner of sale (including, to the extent applicable, the purchase price, the
name of any underwriter, agent or broker-dealer to or through whom such
distribution was made, and the amount of any selling commissions or other items
constituting compensation to such underwriter, agent or broker-dealer) and the
number of shares of Common Stock that will be owned beneficially by such
Stockholder after giving effect to such sale.

SECTION 8.        EXCHANGE ACT COMPLIANCE.

         The Corporation shall comply with all of the reporting requirements of
the Exchange Act applicable to it (whether or not it shall be required to do so,
but specifically excluding Section 14 of the Exchange Act if not then applicable
to the Corporation) and shall comply with all other public information reporting
requirements of the Commission which are conditions to the availability of Rule
144 for the resale of the Registrable Shares by the Stockholders. The
Corporation shall cooperate with the Stockholders in supplying such information
as may be necessary for the Stockholders to complete and file any information
reporting forms presently or hereafter required by the Commission as a condition
to the availability of Rule 144.

                                      -9-
<PAGE>   11
SECTION 9.        NO CONFLICT OF RIGHTS; BEST REGISTRATION RIGHTS

         (a) The Corporation represents and warrants to the Stockholders that
the registration rights granted to the Stockholders hereby do not conflict with
any other registration rights granted by the Corporation. The Corporation shall
not, after the date hereof, grant any registration rights which conflict with or
impair the registration rights granted hereby.

         (b) If, on or before the first anniversary of the date of this
Agreement, the Corporation grants to any person with respect to any security
issued by the Corporation or any of its Subsidiaries registration rights (other
than with respect to Non-Covered Registrations or as contemplated by the proviso
set forth in Section 14 hereof) that provide for terms that are in any manner
(with respect to such registration rights) more favorable to the holder of such
registration rights than the terms granted to the Holders (or if the Corporation
amends or waives any provision of any agreement providing registration rights
(other than with respect to Non-Covered Registrations or as contemplated by the
proviso set forth in Section 14 hereof) of others or takes any other action
whatsoever to provide for terms (with respect to such registration rights) that
are more favorable to other holders than the terms provided to the Holders) then
this Agreement shall immediately be deemed amended to provide the Holders of

SECTION 14.       MODIFICATIONS; AMENDMENTS; WAIVERS.

         The terms and provisions of this Agreement may not be modified or
amended, nor may any provision be waived, except pursuant to a writing signed by
the Corporation and the holders of fifty-one percent (51%) or more of the
Registrable Shares; provided, however, that this Agreement shall be
automatically amended to include as Holders those shareholders of mobilePosition
AB who, after executing one of the Acquisition Agreements and transferring all
of their shares in mobile Position to the Corporation or its affiliate in
accordance with the terms of the Acquisition Agreements, obtains Consideration
Shares (as defined in the Acquisition Agreements) .

SECTION 15.       COUNTERPARTS; FACSIMILE SIGNATURES.

         This Agreement may be executed in any number of counterparts, and each
such counterpart hereof shall be deemed to be an original instrument, but all

SECTION 16.       HEADINGS.

         The headings of the various sections of this Agreement have been

SECTION 17.       SEVERABILITY.

         It is the desire and intent of the parties that the provisions of this
Agreement be enforced to the fullest extent permissible under the law and public
policies applied in each jurisdiction in which enforcement is sought.
Accordingly, if any provision of this Agreement would be held in any
jurisdiction to be invalid, prohibited or unenforceable for any reason, such
provision, as to such jurisdiction, shall be ineffective, without invalidating
the remaining provisions of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction. Notwithstanding the
foregoing, if such provision could be more narrowly drawn so as not to be
invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such
jurisdiction, be so narrowly drawn, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of such
provision in any other jurisdiction.

SECTION 18.       GOVERNING LAW.

         This Agreement shall be governed by and construed and enforced in
