            2.    Registration Under the Securities Act.

            (a)   Except as set forth in Section 2(b) below, the Company agrees
      to file under the Securities Act, no later than 90 days after the Closing
      Date, a registration statement relating to an offer to exchange (such
      registration statement, the "Exchange Offer Registration Statement", and
      such offer, the "Exchange Offer") any and all of the Securities for a like
      aggregate principal amount of debt securities issued by the Company and
      guaranteed by the Subsidiary Guarantors, which debt securities and
      subsidiary guaranties are substantially identical to the Securities (and
      are entitled to the benefits of a trust indenture which is substantially
      identical to the Indenture or is the Indenture and which has been
      qualified under the Trust Indenture Act), except that they have been
      registered pursuant to an effective registration statement under the
      Securities Act and do not contain provisions for the additional interest
      contemplated in Section 2(c) below (such new debt securities hereinafter
      called "Exchange Securities"). The Company agrees to use its reasonable
      best efforts to cause the Exchange Offer Registration Statement to become
      effective under the Securities Act no later than 180 days after the
      Closing Date. The Exchange Offer will be registered under the Securities
      Act on the appropriate form and will comply with all applicable tender
      offer rules and regulations under the Exchange Act. The Company further
      agrees to use its reasonable best efforts to commence and complete the
      Exchange Offer as soon as practicable after such registration statement
      has become effective, hold the

                                       4

                                                   Registration Rights Agreement

      Exchange Offer open for at least 30 days and exchange the Exchange
      Securities for all Registrable Securities that may legally be exchanged in
      the Exchange Offer and that have been properly tendered and not withdrawn
      on or prior to the expiration of the Exchange Offer.  The Exchange Offer
      will be deemed to have been "completed" only if the debt securities and
      subsidiary guaranties received by holders other than Restricted Holders in
      the Exchange Offer for Registrable Securities are, upon receipt,
      transferable by each such holder without restriction under the Securities
      Act (except for the requirement to deliver a prospectus included in the
      Exchange Offer Registration Statement applicable to resales by
      broker-dealers of Exchange Securities received by them pursuant to the
      Exchange Offer in exchange for Securities other than those acquired by
      such broker-dealers directly from the Company) and the Exchange Act and
      without material restrictions under the blue sky or securities laws of a
      substantial majority of the States of the United States of America. The
      Exchange Offer shall be deemed to have been completed upon the earlier to
      occur of (i) the Company having exchanged the Exchange Securities for all
      outstanding Registrable Securities pursuant to the Exchange Offer and (ii)
      the Company having exchanged, pursuant to the Exchange Offer, Exchange
      Securities for all Registrable Securities that may legally be exchanged in
      the Exchange Offer and that have been properly tendered and not withdrawn
      before the expiration of the Exchange Offer, which shall be on a date that
      is at least 30 days following the commencement of the Exchange Offer. The
      Company agrees (x) (other than resales by broker-dealers of Exchange
      Securities received by them pursuant to the Exchange Offer in exchange for
      Securities acquired by them directly from the Company) to include in the
      Exchange Offer Registration Statement a prospectus for use in any resales
      by any holder of Exchange Securities that is a broker-dealer and (y) to
      keep such Exchange Offer Registration Statement effective, and to amend
      and supplement the prospectus contained therein as necessary, for a period
      (the "Resale Period") beginning when Exchange Securities are first issued
      in the Exchange Offer and ending upon the earlier of the expiration of the
      180th day after the Exchange Offer has been completed or such time as such
      broker-dealers no longer own any Registrable Securities (or for such
      longer period if extended pursuant to the terms of this Agreement). With
      respect to such Exchange Offer Registration Statement, such holders shall
      have the benefit of the rights of indemnification and contribution set
      forth in Sections 6(a), (c), (d) and (e) hereof. If, upon consummation of
      the Exchange Offer, any Purchaser holds Securities acquired as part of its
      initial distribution, the Company, simultaneously with the delivery of the
      Exchange Securities pursuant to the Exchange Offer, shall issue and
      deliver to such Purchaser, upon written request of such Purchaser, in
      exchange for the Securities held by such Purchaser, a like principal
      amount of debt securities of the Company issued under the Indenture and
      identical in all material respects to the Securities (the "Private
      Exchange Securities").

            (b)   Subject to Section 3(i), if (i) on or prior to the time the
      Exchange Offer is completed existing Commission interpretations are
      changed such that the debt securities or the Subsidiary Guaranties
      received by holders other than Restricted Holders in the Exchange Offer
      for Registrable Securities are not or would not be, upon receipt,
      transferable by each such holder without restriction under the Securities
      Act (except for the requirement to deliver a prospectus included in the
      Exchange Offer Registration Statement applicable to resales by
      broker-dealers of Exchange Securities received by them pursuant to the
      Exchange Offer in exchange for Securities other than those acquired by
      such broker-dealers directly from the Company), (ii) the Exchange Offer
      has not been completed within 220 days following the Closing Date, (iii)
      any Purchaser so requests with respect to the Securities not eligible to
      be exchanged for Exchange Securities in the Exchange Offer and held by it
      following consummation of the Exchange Offer or (iv) the Exchange Offer is
      not available to any holder of the Securities (other than a broker-dealer
      participating in the

                                       5

                                                   Registration Rights Agreement

      Exchange Offer), the Company shall, in lieu of (or, in the case of clause
      (iii) or (iv), in addition to) conducting the Exchange Offer contemplated
      by Section 2(a), file under the Securities Act no later than the later of
      75 days after the time such obligation to file arises, a "shelf"
      registration statement providing for the registration of, and the sale on
      a continuous or delayed basis by the holders of, all of the Registrable
      Securities, pursuant to Rule 415 or any similar rule that may be adopted
      by the Commission (such filing, the "Shelf Registration" and such
      registration statement, the "Shelf Registration Statement"). The Company
      agrees to use its reasonable best efforts (x) to cause the Shelf
      Registration Statement to become or be declared effective (a) in the case
      of clause (i) above, no later than 180 days after the Closing Date, and
      (b) in the case of clause (ii), (iii) or (iv) above, no later than 75 days
      after the date such Shelf Registration Statement is filed; and, subject to
      Section 3(i), to keep such Shelf Registration Statement continuously
      effective for a period ending on the earlier of the second anniversary of
      the Effective Time (or for such longer period if extended pursuant to the
      terms of this Agreement) or such time as there are no longer any
      Registrable Securities outstanding; provided, however, that no holder
      shall be entitled to be named as a selling securityholder in the Shelf
      Registration Statement or to use the prospectus forming a part thereof for
      resales of Registrable Securities unless such holder agrees in writing to
      be bound by all of the provisions of this Agreement and such holder is an
      Electing Holder, and (y) after the Effective Time of the Shelf
      Registration Statement, promptly upon the request of any holder of
      Registrable Securities that is not then an Electing Holder, to take any
      action reasonably necessary to enable such holder to use the prospectus
      forming a part thereof for resales of Registrable Securities, including,
      without limitation, any action necessary to identify such holder as a
      selling securityholder in the Shelf Registration Statement; provided,
      however, that nothing in this Clause (y) shall relieve any such holder of
      the obligation to return a completed and signed Notice and Questionnaire
      to the Company in accordance with Section 3(d)(iii) hereof. The Company
      further agrees to supplement or make amendments to the Shelf Registration
      Statement, as and when required by the rules, regulations or instructions
      applicable to the registration form used by the Company for such Shelf
      Registration Statement or by the Securities Act or rules and regulations
      thereunder for shelf registration, and the Company agrees to furnish to
      each Electing Holder copies of any such supplement or amendment prior to
      its being used or promptly following its filing with the Commission.

            (c)   In the event that (i) the Company has not filed the Exchange
      Offer Registration Statement or Shelf Registration Statement on or before
      the date on which such registration statement is required to be filed
      pursuant to Section 2(a) or 2(b), respectively, or (ii) such Exchange
      Offer Registration Statement or Shelf Registration Statement has not
      become effective or been declared effective by the Commission on or before
      the date on which such registration statement is required to become or be
      declared effective pursuant to Section 2(a) or 2(b), respectively, or
      (iii) the Exchange Offer has not been completed on or before the 40th day
      after the initial effective date of the Exchange Offer Registration
      Statement relating to the Exchange Offer (if the Exchange Offer is then
      required to be made) or (iv) any Shelf Registration Suspension exceeds the
      number of days permitted for such suspension under Section 3(i), or (v)
      any Exchange Offer Registration Statement or Shelf Registration Statement
      required by Section 2(a) or 2(b) hereof is filed and declared effective
      but shall thereafter either be withdrawn by the Company or shall become
      subject to an effective stop order issued pursuant to Section 8(d) of the
      Securities Act suspending the effectiveness of such registration statement
      (except as specifically permitted herein) without being succeeded as
      promptly as practicable by an additional registration statement filed and
      declared effective (each such event referred to in clauses (i) through
      (v), a "Registration Default" and each period during which a Registration
      Default has occurred and is

                                       6

      continuing, a "Registration Default Period"), then, as liquidated damages
      for such Registration Default, subject to the provisions of Section 9(b),
      additional interest ("Additional Interest"), in addition to the Base
      Interest, shall accrue at a per annum rate of 0.25% for the first 90 days
      of the Registration Default Period, at a per annum rate of 0.50% for the
      second 90 days of the Registration Default Period, at a per annum rate of
      0.75% for the third 90 days of the Registration Default Period and at a
      per annum rate of 1.0% thereafter for the remaining portion of the
      Registration Default Period.

            (d)   The Company shall take, and shall cause the Subsidiary
      Guarantors to take, all actions reasonably necessary or advisable to be
      taken by it to ensure that the transactions contemplated herein are
      effected as so contemplated.

            (e)   Any reference herein to a registration statement as of any
      time shall be deemed to include any document incorporated, or deemed to be
      incorporated, therein by reference as of such time and any reference
      herein to any post-effective amendment to a registration statement as of
      any time shall be deemed to include any document incorporated, or deemed
      to be incorporated, therein by reference as of such time.

            3.    Registration Procedures.

                If the Company files a registration statement pursuant to
Section 2(a) or Section 2(b), the following provisions shall apply:

            (a)   At or before the Effective Time of the Exchange Offer or the
      Shelf Registration, as the case may be, the Company shall qualify the
      Indenture under the Trust Indenture Act of 1939.

            (b)   In the event that such qualification would require the
      appointment of a new trustee under the Indenture, the Company shall
      appoint a new trustee thereunder pursuant to the applicable provisions of
      the Indenture.

            (c)   In connection with the Company's obligations with respect to
      the registration of Exchange Securities as contemplated by Section 2(a)
      (the "Exchange Registration"), if applicable, the Company shall:

                        (i)   prepare and file with the Commission no later than

                  Securities or as an underwriter, a placement or sales agent or
                  a broker or dealer in respect thereof, or otherwise, assist
                  such broker-dealer in complying with the requirements of such
                  Conduct Rules, including by (A) if such Conduct Rules shall so
                  require, engaging a "qualified independent underwriter" (as
                  defined in such Conduct Rules) to participate in the
                  preparation of the Shelf Registration Statement relating to
                  such Registrable Securities, to exercise usual standards of
                  due diligence in respect thereto and, if any portion of the
                  offering contemplated by such Shelf Registration Statement is
                  an underwritten offering or is made through a placement or
                  sales agent, to recommend the yield of such Registrable

                  underwriter to the extent of the indemnification of
                  underwriters provided in Section 6 hereof, and (C) providing
                  such information to such broker-dealer as may be required in
                  order for such broker-dealer to comply with the requirements
                  of the Conduct Rules;

                        (xxi)permit holders to withdraw tendered securities at
                  any time prior to the close of business, New York time, on the
                  last business day on which the Registered Exchange Offer shall
                  remain open; and

                        (xxii) comply with all applicable rules and regulations
                  of the Commission, and make generally available to its
                  securityholders as soon as practicable but in any event not
                  later than eighteen months after the effective date of such
                  Shelf Registration Statement, an earning statement of the
                  Company complying with Section 11(a) of the Securities Act
                  (including, at the option of the Company, Rule 158
                  thereunder).

            (e)   Subject to Section 3(i), in the event that the Company would
      be required, pursuant to Section 3(d)(ix)(F) above, to notify the Electing
      Holders, the placement or sales agent, if any, therefor and the managing
      underwriters, if any, thereof, the Company shall without unreasonable
      delay prepare and furnish to each of the Electing Holders, to each
      placement or sales agent, if any, and to each such underwriter, if any, a
      reasonable number of copies of a prospectus supplemented or amended so
      that, as thereafter delivered to purchasers of Registrable Securities,
      such prospectus shall conform in all material respects to the applicable
      requirements of the Securities Act and the Trust Indenture Act and the
      rules and regulations of the Commission thereunder and shall not contain
      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. Each Electing
      Holder agrees that upon receipt of any notice from the Company pursuant to
      Section 3(d)(ix)(F) hereof, such Electing Holder shall forthwith
      discontinue the disposition of Registrable Securities pursuant to the
      Shelf Registration Statement applicable to such Registrable Securities
      until such Electing Holder shall have received copies of such amended or
      supplemented prospectus, and if so directed by the Company, such Electing
      Holder shall deliver to the Company (at the Company's expense) all copies,
      other than permanent file copies, then in such Electing Holder's
      possession of the prospectus covering such Registrable Securities at the
      time of receipt of such notice and, the period of effectiveness of the
      Shelf Registration Statement provided for in 2(b) shall each be extended
      by the number of days from and including the date of giving of such notice
      to and

                                                   Registration Rights Agreement

      including the date the holders of the Securities shall have received such
      amended or supplemented prospectus.

            (f)   In the event of a Shelf Registration, in addition to the
      information required to be provided by each Electing Holder in its Notice
      Questionnaire, the Company may require such Electing Holder to furnish to
      the Company such additional information regarding such Electing Holder and
      such Electing Holder's intended method of distribution of Registrable
      Securities as may be required in order to comply with the Securities Act.
      Each such Electing Holder agrees to notify the Company as promptly as
      practicable of any inaccuracy or change in information previously
      furnished by such Electing Holder to the Company or of the occurrence of
      any event in either case as a result of which any prospectus relating to
      such Shelf Registration contains or would contain an untrue statement of a
      material fact regarding such Electing Holder or such Electing Holder's
      intended method of disposition of such Registrable Securities or omits to
      state any material fact regarding such Electing Holder or such Electing
      Holder's intended method of disposition of such Registrable Securities
      required to be stated therein or necessary to make the statements therein
      not misleading in light of the circumstances then existing, and promptly
      to furnish to the Company any additional information required to correct
      and update any previously furnished information or required so that such
      prospectus shall not contain, with respect to such Electing Holder or the
      disposition of such Registrable Securities, 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)   As soon as practicable after the close of an Exchange Offer,
      the Company shall deliver to the Trustee for cancellation all Securities
      so accepted for exchange and cause the Trustee to authenticate and deliver
      promptly to each Holder of the Securities, Exchange Securities or Private
      Securities, as the case may be, equal in principal amount to the
      Securities of such holder so accepted for exchange.

            (h)   Until the expiration of two years after the Closing Date, the
      Company will not, and will not permit any of its "affiliates" (as defined
      in Rule 144) to, resell any of the Securities that have been reacquired by
      any of them except pursuant to an effective registration statement under
      the Securities Act.

            (i)   Notwithstanding anything in Section 2(b) or Section 3(d) or
      (e) to the contrary, if the Company determines in good faith that the
      filing of any supplement or amendment to a Shelf Registration Statement,
      including without limitation a supplement or amendment contemplated by
      Section 3(e) hereof, would require the disclosure of information that the
      Company has a bona fide business reason to preserve as confidential, or
      the disclosure of which would materially adversely affect the Company's
      ability to consummate a transaction (whether or not a final decision has
      been made to undertake such transaction), then upon written notice of such
      determination by the Company (a "Suspension Notice") to the Electing
      Holders, the obligation of the Company to supplement or amend the Shelf
      Registration Statement (including any action with respect thereto
      contemplated by Section 3(e)) will be suspended until the Company notifies
      the Electing Holders (a "Suspension Termination Notice") that the reasons
      for suspension of such obligations on the part of the Company no longer
      exist and the Company amends or supplements the Shelf Registration
      Statement as may be required (such suspension, a "Shelf Registration
      Suspension"); provided that the aggregate number of days (whether or not
      consecutive) during which the Company may delay the filing of any such
      supplement or amendment shall in no event exceed (i) 30 days during any
      period of 90 consecutive days or (ii) 90 days during any period of 12
      consecutive

      months, and the suspension of the Company's obligation to supplement or
      amend the Shelf Registration Statement under the preceding sentence shall
      not result in any obligation of the Company to pay Additional Interest
      pursuant to Section 2(c). If the Company delivers a Suspension Notice in
      accordance with this Section 3(i), then the Electing Holders shall suspend
      use of the prospectus until the Company delivers a Suspension Termination
      Notice in accordance with this Section 3(i).

            (j)   As a condition to its participation in the Exchange Offer
      pursuant to the terms of this Exchange and Registration Rights Agreement,
      each holder of Registrable Securities shall furnish, upon the request of
      the Company, prior to the consummation thereof, written representations to
      the Company (which may be contained in the letter of transmittal
      contemplated by the Exchange Offer Registration Statement) in form and
      substance customary for exchange offers similar to the Exchange Offer,
      including without limitation representations to the effect that such
      holder (i) is not an affiliate of the Company or any Subsidiary Guarantor,
      (ii) is not engaged in, and does not intend to engage in, and has no
      arrangement or understanding with any person to participate in, a
      distribution of the Exchange Securities to be issued in the Exchange Offer
      and (iii) is acquiring the Exchange Securities in its ordinary course of
      business.

        4.  Registration Expenses.

      underwriting agreement relating thereto, will conform in all material
      respects to the requirements of the Securities Act and the Trust Indenture
      Act and the rules and regulations of the Commission thereunder and will
      not contain an untrue statement of a material fact or omit to state a

      or Section 3(c)(iv)(F) hereof until (ii) such time as the Company
      furnishes an amended or supplemented prospectus pursuant to Section 3(e)

      Securities expressly for use therein.

      shall not apply to any statements or omissions made in reliance upon and
      in conformity with information furnished in writing to the Company by a
      holder of Registrable Securities expressly for use therein.

            (c)   The compliance by the Company with all of the provisions of
      this Registration Rights Agreement and the consummation of the
      transactions herein contemplated will not conflict with or result in a
      breach of any of the terms or provisions of, or constitute a default
      under, any indenture, mortgage, deed of trust, loan agreement or other
      agreement or instrument to which the Company or any subsidiary of the
      Company is a party or by which the Company or any subsidiary of the
      Company is bound or to which any of the property or assets of the Company
      or any subsidiary of the Company is subject, nor will such action result
      in any violation of the provisions of the certificate of incorporation, as
      amended, or the by-laws of the Company or any Subsidiary Guarantor or any
      statute or any order, rule or regulation of any court or governmental
      agency or body having jurisdiction over the Company or any subsidiary of
      the Company or any of their properties except, in each case other than
      with respect to such certificate of incorporation or by-laws, for any such
      conflict, breach, violation or default that would not, individually or in
      the aggregate, have a material adverse effect on the condition (financial
      or other), business, properties, earnings, assets, stockholders' equity,
      prospects or results of operations of the Company and its subsidiaries
      taken as a whole; and no consent, approval, authorization, order,
      registration or qualification of or with any such court or governmental
      agency or body is required for the consummation by the Company and the

      Securities.

            (d)   This Registration Rights Agreement has been duly authorized,

            6.    Indemnification.

      indemnify and hold harmless each of the holders of Registrable Securities
      included in an Exchange Offer Registration Statement, each of the Electing
      Holders of Registrable Securities included in a Shelf Registration

      or as an underwriter in any offering or sale of such Registrable
      Securities against any losses, claims, damages or liabilities, joint or
      several, to which such holder, agent or underwriter may become subject
      under the Securities Act or otherwise, insofar as such losses, claims,
      damages or liabilities (or actions in respect thereof) arise out of or are
      based upon an untrue statement or alleged untrue statement of a material
      fact contained in any Exchange Offer Registration Statement or Shelf
      Registration Statement, as the case may be, under which such Registrable
      Securities were registered under the Securities Act, or any preliminary,
      final or summary prospectus contained therein or furnished by the Company
      to any such holder, Electing Holder, agent or underwriter, or any
      amendment or supplement thereto, or 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, and will reimburse such holder, such Electing Holder, such
      agent and such underwriter for any legal or other expenses reasonably
      incurred by them in connection with investigating or defending any such
      action or claim as such expenses are incurred;

      provided, however, that neither the Company nor any Subsidiary Guarantor
      shall be liable to any such person in any such case to the extent that any
      such loss, claim, damage or liability arises out of or is based upon an
      untrue statement or alleged untrue statement or omission or alleged
      omission made in such registration statement, or preliminary, final or
      summary prospectus, or amendment or supplement thereto, in reliance upon
      and in conformity with written information furnished to the Company by
      such person expressly for use therein; provided, further, that neither the
      Company nor any Subsidiary Guarantor shall be liable for any losses,
      claims, damages or liabilities, joint or several, arising out of an offer
      or sale of Registrable Securities (i) during any Shelf Registration
      Suspension in accordance with Section 3(i) hereof during the permitted
      time periods provided for therein; provided the Company provides the
      Suspension Notice, or (ii) under the circumstances described in Section
      3(c)(iv) hereof, during the period following any notification in writing
      of Purchasers, holders and broker-dealers referred to therein, provided
      such period is not unreasonably long.

            (b)   Indemnification by the Holders and any Agents and
      Underwriters. The Company may require, as a condition to including any
      Registrable Securities in any registration statement filed pursuant to
      Section 2(b) hereof and to entering into any underwriting agreement with
      respect thereto, that the Company shall have received an undertaking
      reasonably satisfactory to it from the Electing Holder of such Registrable
      Securities and from each underwriter named in any such underwriting
      agreement, severally and not jointly, to (i) indemnify and hold harmless
      the Company and each Subsidiary Guarantor, and all other holders of
      Registrable Securities, against any losses, claims, damages or liabilities
      to which the Company, the Subsidiary Guarantors or such other holders of
      Registrable Securities may become subject, joint or several, under the
      Securities Act or otherwise, insofar as such losses, claims, damages or
      liabilities (or actions in respect thereof) arise out of or are based upon
      an untrue statement or alleged untrue statement of a material fact
      contained in such registration statement, or any preliminary, final or
      summary prospectus contained therein or furnished by the Company to any
      such Electing Holder, agent or underwriter, or any amendment or supplement
      thereto, or 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, in each case to
      the extent, but only to the extent, that such untrue statement or alleged
      untrue statement or omission or alleged omission was made in reliance upon
      and in conformity with written information furnished to the Company by
      such Electing Holder or underwriter expressly for use therein, and (ii)
      reimburse the Company and the Subsidiary Guarantors for any legal or other
      expenses reasonably incurred by the Company and the Subsidiary Guarantors
      in connection with investigating or defending any such action or claim as
      such expenses are incurred; provided, however, that no such Electing
      Holder shall be required to undertake liability to any person under this
      Section 6(b) for any amounts in excess of the dollar amount of the
      proceeds to be received by such Electing Holder from the sale of such
      Electing Holder's Registrable Securities pursuant to such registration.

            (c)   Notices of Claims, Etc. Promptly after receipt by an
      indemnified party under subsection (a) or (b) above of written notice of
      the commencement of any action, such indemnified party shall, if a claim
      in respect thereof is to be made against an indemnifying party pursuant to
      the indemnification provisions of or contemplated by this Section 6,
      notify such indemnifying party in writing of the commencement of such
      action; but the omission so to notify the indemnifying party shall not
      relieve it from any liability which it may have to any indemnified party
      otherwise than under the indemnification provisions of or contemplated by
      Section 6(a) or 6(b) hereof. In case any such action shall be brought
      against any

      indemnified party and it shall notify an indemnifying party of the
      commencement thereof, such indemnifying party shall be entitled to
      participate therein and, to the extent that it shall wish, jointly with
      any other indemnifying party similarly notified, to assume the defense
      thereof, with counsel reasonably satisfactory to such indemnified party
      (who shall not, except with the consent of the indemnified party, be
      counsel to the indemnifying party), and, after notice from the
      indemnifying party to such indemnified party of its election so to assume
      the defense thereof, such indemnifying party shall not be liable to such
      indemnified party for any legal expenses of other counsel or any other
      expenses, in each case subsequently incurred by such indemnified party, in
      connection with the defense thereof other than reasonable costs of
      investigation. No indemnifying party shall, without the written consent of
      the indemnified party, effect the settlement or compromise of, or consent
      to the entry of any judgment with respect to, any pending or threatened
      action or claim in respect of which indemnification or contribution may be
      sought hereunder (whether or not the indemnified party is an actual or
      potential party to such action or claim) unless such settlement,
      compromise or judgment (i) includes an unconditional release of the
      indemnified party from all liability arising out of such action or claim
      and (ii) does not include a statement as to or an admission of fault,
      culpability or a failure to act by or on behalf of any indemnified party.

            (d)   Contribution. If for any reason the indemnification provisions
      contemplated by Section 6(a) or Section 6(b) are unavailable to or
      insufficient to hold harmless an indemnified party in respect of any
      losses, claims, damages or liabilities (or actions in respect thereof)
      referred to therein, then each indemnifying party shall contribute to the
      amount paid or payable by such indemnified party as a result of such
      losses, claims, damages or liabilities (or actions in respect thereof) in
      such proportion as is appropriate to reflect the relative fault of the
      indemnifying party and the indemnified party in connection with the
      statements or omissions which resulted in such losses, claims, damages or
      liabilities (or actions in respect thereof), as well as any other relevant
      equitable considerations. The relative fault of such indemnifying party
      and indemnified party shall be determined by reference to, among other
      things, whether the untrue or alleged untrue statement of a material fact
      or omission or alleged omission to state a material fact relates to
      information supplied by such indemnifying party or by such indemnified
      party, and the parties' relative intent, knowledge, access to information
      and opportunity to correct or prevent such statement or omission. The
      parties hereto agree that it would not be just and equitable if
      contributions pursuant to this Section 6(d) were determined by pro rata
      allocation (even if the holders or any agents or underwriters or all of
      them were treated as one entity for such purpose) or by any other method
      of allocation which does not take account of the equitable considerations
      referred to in this Section 6(d). The amount paid or payable by an
      indemnified party as a result of the losses, claims, damages, or
      liabilities (or actions in respect thereof) referred to above shall be
      deemed to include any legal or other fees or expenses reasonably incurred
      by such indemnified party in connection with investigating or defending
      any such action or claim. Notwithstanding the provisions of this Section
      6(d), no holder shall be required to contribute any amount in excess of
      the amount by which the dollar amount of the proceeds received by such
      holder from the sale of any Registrable Securities (after deducting any
      fees, discounts and commissions applicable thereto) exceeds the amount of
      any damages which such holder has otherwise been required to pay by reason
      of such untrue or alleged untrue statement or omission or alleged
      omission, and no underwriter shall be required to contribute any amount in
      excess of the amount by which the total price at which the Registrable
      Securities underwritten by it and distributed to the public were offered
      to the public exceeds the amount of any damages which such underwriter has
      otherwise been required to pay by reason of such untrue or

      alleged untrue statement or omission or alleged omission. No person guilty
      of fraudulent misrepresentation (within the meaning of Section 11(f) of
      the Securities Act) shall be entitled to contribution from any person who
      was not guilty of such fraudulent misrepresentation. The holders' and any
      underwriters' obligations in this Section 6(d) to contribute shall be
      several in proportion to the principal amount of Registrable Securities
      registered or underwritten, as the case may be, by them and not joint.

            (e)   The obligations of the Company and each Subsidiary Guarantor
      under this Section 6 shall be in addition to any liability which the
      Company or any Subsidiary Guarantor may otherwise have and shall extend,
      upon the same terms and conditions, to each officer, director and partner
      of each holder, agent and underwriter and each person, if any, who
      controls any holder, agent or underwriter within the meaning of the
      Securities Act; and the obligations of the holders and any agents or
      underwriters contemplated by this Section 6 shall be in addition to any
      liability which the respective holder, agent or underwriter may otherwise
      have and shall extend, upon the same terms and conditions, to each
      officer, director, manager and partner, as the case may be, of the Company
      or any Subsidiary Guarantor and to each person, if any, who controls the
      Company or any Subsidiary Guarantor within the meaning of the Securities
      Act.

            7.    Underwritten Offerings.

            (a)   Selection of Underwriters. If any of the Registrable
      Securities covered by the Shelf Registration are to be sold pursuant to an
      underwritten offering, the managing underwriter or underwriters thereof
      shall be designated by Electing Holders holding at least a majority in
      aggregate principal amount of the Registrable Securities to be included in
      such offering, provided that such designated managing underwriter or
      underwriters is or are reasonably acceptable to the Company.

            (b)   Participation by Holders. Each holder of Registrable
      Securities hereby agrees with each other such holder that no such holder
      may participate in any underwritten offering hereunder unless such holder
      (i) agrees to sell such holder's Registrable Securities on the basis
      provided in any underwriting arrangements approved by the persons entitled
      hereunder to approve such arrangements and (ii) completes and executes all
      questionnaires, powers of attorney, indemnities, underwriting agreements
      and other documents reasonably required under the terms of such
      underwriting arrangements.

            8.    Rule 144.

                  The Company covenants to the holders of Registrable Securities
that to the extent it shall be required to do so under the Exchange Act, the
Company shall timely file the reports required to be filed by it under the
Exchange Act or the Securities Act (including the reports under Section 13 and
15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144 adopted
by the Commission under the Securities Act) and the rules and regulations
adopted by the Commission thereunder, and shall take such further action as any
holder of Registrable Securities may reasonably request, all to the extent
required from time to time to enable such holder to sell Registrable Securities
without registration under the Securities Act within the limitations of the
exemption provided by Rule 144 under the Securities Act, as such Rule may be
amended from time to time, or any similar or successor rule or regulation
hereafter adopted by the Commission. Upon the request of any holder of
Registrable Securities in connection with that holder's sale pursuant to Rule
144, the Company shall deliver to such holder a written statement as to whether
it has complied with such requirements.

                                                   Registration Rights Agreement

            9.    Miscellaneous.

            (a)   No Inconsistent Agreements. The Company represents, warrants,
      covenants and agrees that it has not granted, and shall not grant,
      registration rights with respect to Registrable Securities or any other
      securities which would be inconsistent with the terms contained in this
      Registration Rights Agreement.

            (b)   Specific Performance. The parties hereto acknowledge that
      there would be no adequate remedy at law if the Company fails to perform
      any of its obligations hereunder and that the Purchasers and the holders
      from time to time of the Registrable Securities may be irreparably harmed
      by any such failure, and accordingly agree that the Purchasers and such
      holders, in addition to any other remedy to which they may be entitled at
      law or in equity, shall be entitled to compel specific performance of the
      obligations of the Company under this Registration Rights Agreement in
      accordance with the terms and conditions of this Registration Rights
      Agreement, in any court of the United States or any State thereof having
      jurisdiction.

            (c)   Notices. All notices, requests, claims, demands, waivers and
      other communications hereunder shall be in writing and shall be deemed to
      have been duly given when delivered by hand, if delivered personally or by
      courier, or three days after being deposited in the mail (registered or
      certified mail, postage prepaid, return receipt requested) as follows: If
      to the Company, to it at Encore Acquisition Company, 777 Main Street,
      Suite 1400, Ft. Worth, Texas 76102, Attention: President, and if to a
      holder, to the address of such holder set forth in the security register
      or other records of the Company, or to such other address as the Company
      or any such holder may have furnished to the other in writing in
      accordance herewith, except that notices of change of address shall be
      effective only upon receipt.

            (d)   Parties in Interest. All the terms and provisions of this
      Registration Rights Agreement shall be binding upon, shall inure to the
      benefit of and shall be enforceable by the parties hereto and the holders
      from time to time of the Registrable Securities and the respective
      successors and assigns of the parties hereto and such holders. In the
      event that any transferee of any holder of Registrable Securities shall
      acquire Registrable Securities, in any manner, whether by gift, bequest,
      purchase, operation of law or otherwise, such transferee shall, without
      any further writing or action of any kind, be deemed a beneficiary hereof
      for all purposes and such Registrable Securities shall be held subject to
      all of the terms of this Registration Rights Agreement, and by taking and
      holding such Registrable Securities such transferee shall be entitled to
      receive the benefits of, and be conclusively deemed to have agreed to be
      bound by all of the applicable terms and provisions of this Registration
      Rights Agreement. If the Company shall so request, any such successor,
      assign or transferee shall agree in writing to acquire and hold the
      Registrable Securities subject to all of the applicable terms hereof.

            (e)   Survival. The respective indemnities, agreements,
      representations, warranties and each other provision set forth in this
      Registration Rights Agreement or made pursuant hereto shall remain in full
      force and effect regardless of any investigation (or statement as to the
      results thereof) made by or on behalf of any holder of Registrable
      Securities, any director, officer or partner of such holder, any agent or
      underwriter or any director, officer or partner thereof, or any
      controlling person of any of the foregoing, and shall survive delivery of
      and payment for the Registrable Securities pursuant to the Purchase
      Agreement and the transfer and registration of Registrable Securities by
      such holder and the consummation of an Exchange Offer.

            (f)   GOVERNING LAW. THIS REGISTRATION RIGHTS AGREEMENT SHALL BE
      GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW
      YORK.

            (g)   Headings. The descriptive headings of the several Sections and
      paragraphs of this Registration Rights Agreement are inserted for

      Agreement and shall not affect in any way the meaning or interpretation of
      this Registration Rights Agreement.

            (h)   Entire Agreement; Amendments. This Registration Rights
      Agreement and the other writings referred to herein (including the

      form a part hereof contain the entire understanding of the parties with
      respect to its subject matter. This Registration Rights Agreement
      supersedes all prior agreements and understandings between the parties
      with respect to its subject matter. This Registration Rights Agreement may
      be amended and the observance of any term of this Registration Rights
      Agreement may be waived (either generally or in a particular instance and
      either retroactively or prospectively) only by a written instrument duly
      executed by the Company and the holders of at least a majority in
      aggregate principal amount of the Registrable Securities at the time
      outstanding. Each holder of any Registrable Securities at the time or
      thereafter outstanding shall be bound by any amendment or waiver effected
      pursuant to this Section 9(h), whether or not any notice, writing or
      marking indicating such amendment or waiver appears on such Registrable
      Securities or is delivered to such holder.

            (i)   Inspection. For so long as this Registration Rights Agreement
      shall be in effect, this Registration Rights Agreement and a complete list
      of the names and addresses of all the holders of Registrable Securities
      shall be made available for inspection and copying on any business day by
      any holder of Registrable Securities for proper purposes only (which shall
      include any purpose related to the rights of the holders of Registrable
      Securities under the Securities, the Indenture and this Agreement) at the
      offices of the Company at the address thereof set forth in Section 9(c)
      above and at the office of the Trustee under the Indenture.

            (j)   Counterparts. This agreement may be executed by the parties in
      counterparts, each of which shall be deemed to be an original, but all
      such respective counterparts shall together constitute one and the same
      instrument.

          (kk) "Rule 16b-3" means Rule 16b-3 of the Exchange Act or any
successor to Rule 16b-3, as in effect when discretion is being exercised with
respect to the Plan.

          (ll) "Section 16(b) " means Section 16(b) of the Exchange Act.

          (mm) "Service Provider" means an Employee, Director or Consultant.

          (nn) "Share" means a share of the Common Stock, as adjusted in
accordance with Section 15 of the Plan.

          (oo) "Stock Appreciation Right" or "SAR" means an Award, granted alone
or in connection with an Option, that pursuant to Section 9 of the Plan is
designated as a SAR.

          (pp) "Subsidiary" means a "subsidiary corporation", whether now or
hereafter existing, as defined in Section 424(f) of the Code.

          (qq) "Tandem SAR" means a SAR that is granted in connection with a
related Option, the exercise of which will require forfeiture of the right to
purchase an equal number of

                                                                             -4-
<PAGE>

Shares under the related Option (and when a Share is purchased under the Option,
the SAR will be canceled to the same extent).

          (rr) "Unvested Awards" shall mean Options or Restricted Stock that (i)
were granted to an individual in connection with such individual's position as a
Service Provider and (ii) are still subject to vesting or lapsing of Company
repurchase rights or similar restrictions.

     3.   Stock Subject to the Plan.

          (a)  Stock Subject to the Plan. Subject to the provisions of Section
15 of the Plan, the maximum aggregate number of Shares that may be optioned and
sold under the Plan is 500,000 Shares, plus (a) the number of Shares which have
been reserved but not issued under the Company's 1999 Stock Plan (the "1999
Plan") as of the Registration Date, (b) any Shares returned to the 1999 Plan as
a result of termination of options or repurchase of Shares issued under such
plan, and (c) an annual increase to be added on the first day of the Company's
Fiscal Year beginning in 2005, equal to the lesser of (i) 1,500,000 Shares, (ii)
3% of the outstanding Shares on such date or (iii) an amount determined by the
Board. The Shares may be authorized, but unissued, or reacquired Common Stock.
Shares shall not be deemed to have been issued pursuant to the Plan with respect
to any portion of an Award that is settled in cash. Upon payment in Shares
pursuant to the exercise of an SAR, the number of Shares available for issuance
under the Plan shall be reduced only by the number of Shares actually issued in
such payment. If a Participant pays the exercise price (or purchase price, if
applicable) of an Award through the tender of Shares, or if Shares are tendered
or withheld to satisfy any Company withholding obligations, the number of Shares
so tendered or withheld shall again be available for issuance pursuant to future
Awards under the Plan.

          (b)  Lapsed Awards. If an Award expires or becomes unexercisable
without having been exercised in full or is surrendered pursuant to an Exchange
Program, or, with respect to Restricted Stock, Performance Shares, Performance
Units or Deferred Stock Units, is forfeited back to or repurchased by the
Company, the unpurchased Shares (or for Awards other than Options and SARs, the
forfeited or repurchased Shares) which were subject thereto shall become
available for future grant or sale under the Plan (unless the Plan has
terminated). However, Shares that have actually been issued under the Plan,
under any Award, shall not be returned to the Plan and shall not become
available for future distribution under the Plan, except that if unvested Shares
of Restricted Stock, Performance Shares, Performance Units or Deferred Stock
Units are repurchased by the Company at their original purchase price or are
forfeited to the Company, such Shares shall become available for future grant
under the Plan. To the extent an Award under the Plan is paid out in cash rather
than stock, such cash payment shall not result in reducing the number of Shares
available for issuance under the Plan.

     4.   Administration of the Plan.

          (a)  Procedure.

               (i)  Multiple Administrative Bodies. Different Committees with
respect to different groups of Service Providers may administer the Plan.

               (ii) Section 162(m). To the extent that the Administrator
determines it to be desirable to qualify Options granted hereunder as
"performance-based compensation" within

                                                                             -5-
<PAGE>

the meaning of Section 162(m) of the Code, the Plan will be administered by a
Committee of two or more "outside directors" within the meaning of Section
162(m) of the Code.

               (iii) Rule 16b-3. To the extent desirable to qualify transactions
hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder
will be structured to satisfy the requirements for exemption under Rule 16b-3.

               (iv) Other Administration. Other than as provided above, the Plan
will be administered by (A) the Board or (B) a Committee, which committee will
be constituted to satisfy Applicable Laws.

          (b)  Powers of the Administrator. Subject to the provisions of the
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator will have the authority, in
its discretion:

               (i)  to determine the Fair Market Value;

               (ii) to select the Service Providers to whom Awards may be
granted hereunder;

               (iii) to determine the number of Shares to be covered by each
Award granted hereunder;

               (iv) to approve forms of agreement for use under the Plan;

               (v)  to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any Award granted hereunder. Such terms and conditions
include, but are not limited to, the exercise price, the time or times when
Awards may be exercised (which may be based on performance criteria), any
vesting acceleration or waiver of forfeiture or repurchase restrictions, and any
restriction or limitation regarding any Award or the Shares relating thereto,
based in each case on such factors as the Administrator, in its sole discretion,
will determine;

               (vi) to reduce the exercise price of any Option or SAR to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Award shall have declined since the date the Award was granted;

               (vii) to institute an Exchange Program;

               (viii) to construe and interpret the terms of the Plan and Awards
granted pursuant to the Plan;

               (ix) to prescribe, amend and rescind rules and regulations
relating to the Plan, including rules and regulations relating to sub-plans
established for the purpose of satisfying applicable foreign laws and/or
qualifying for preferred tax treatment under applicable foreign tax laws;

                                                                             -6-
<PAGE>

               (x)  to modify or amend each Award (subject to Section 18(c) of
the Plan), including the discretionary authority to extend the post-termination
exercisability period of Awards longer than is otherwise provided for in the
Plan;

               (xi) to allow Participants to satisfy withholding tax obligations
by electing to have the Company withhold from the Shares or cash to be issued
upon exercise or vesting of an Award that number of Shares or cash having a Fair
Market Value equal to the minimum amount required to be withheld. The Fair
Market Value of any Shares to be withheld will be determined on the date that
the amount of tax to be withheld is to be determined. All elections by a
Participant to have Shares or cash withheld for this purpose will be made in
such form and under such conditions as the Administrator may deem necessary or
advisable;

               (xii) to authorize any person to execute on behalf of the Company
any instrument required to effect the grant of an Award previously granted by
the Administrator;

               (xiii) to allow a Participant to defer the receipt of the payment
of cash or the delivery of Shares that would otherwise be due to such
Participant under an Award;

               (xiv) to make all other determinations deemed necessary or
advisable for administering the Plan.

          (c)  Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations will be final and binding on all
Participants and any other holders of Awards.

     5.   Eligibility. Nonstatutory Stock Options, Restricted Stock, Stock
Appreciation Rights, Performance Units, Performance Shares and Deferred Stock
Units may be granted to Service Providers. Incentive Stock Options may be
granted only to Employees.

     6.   Limitations.

          (a)  ISO $100,000 Rule. Each Option will be designated in the Award
Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designation, to the extent that the aggregate Fair
Market Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Participant during any calendar year
(under all plans of the Company and any Parent or Subsidiary) exceeds $100,000,
such Options will be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options will be taken into account in the order in
which they were granted. The Fair Market Value of the Shares will be determined
as of the time the Option with respect to such Shares is granted.

          (b)  No Rights as a Service Provider. Neither the Plan nor any Award
shall confer upon a Participant any right with respect to continuing his or her
relationship as a Service Provider, nor shall they interfere in any way with the
right of the Participant or the right of the Company or its Parent or
Subsidiaries to terminate such relationship at any time, with or without cause.

          (c)  162(m) Limitation. The following limitations shall apply to
Awards under the Plan:

                                                                             -7-
<PAGE>

               (i)  No Service Provider will be granted, in any Fiscal Year,
Options or SARs to purchase more than 500,000 Shares.

               (ii) In connection with his or her initial service, a Service
Provider may be granted Options or SARs to purchase up to an additional 500,000
Shares which will not count against the limit set forth in Section 6(c)(i) of
the Plan above.

               (iii) The foregoing limitations will be adjusted proportionately
in connection with any change in the Company's capitalization as described in
Section 15 of the Plan.

               (iv) If an Award is cancelled in the same Fiscal Year in which it
was granted (other than in connection with a transaction described in Section 15
of the Plan), the cancelled Award will be counted against the limits set forth
in subsections (i) and (ii) above. For this purpose, if the exercise price of an
Option is reduced, the transaction will be treated as a cancellation of the
Option and the grant of a new Option.

     7.   Stock Options.

          (a)  Term of Option. The term of each Option will be stated in the
Award Agreement. In the case of an Incentive Stock Option, the term will be ten
(10) years from the date of grant or such shorter term as may be provided in the
Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a
Participant who, at the time the Incentive Stock Option is granted, owns stock
representing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company or any Parent or Subsidiary, the term of the
Incentive Stock Option will be five (5) years from the date of grant or such
shorter term as may be provided in the Award Agreement.

          (b)  Option Exercise Price and Consideration.

               (i)  Exercise Price. The per Share exercise price for the Shares
to be issued pursuant to exercise of an Option will be determined by the
Administrator, subject to the following:

                    (1)  In the case of an Incentive Stock Option

                         a)   granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price will be no less than 110% of the
Fair Market Value per Share on the date of grant.

                         b) granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price will
be no less than 100% of the Fair Market Value per Share on the date of grant.

                    (2)  In the case of a Nonstatutory Stock Option, the per
Share exercise price will be determined by the Administrator. In the case of a
Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of

                                                                             -8-
<PAGE>

the Code, the per Share exercise price will be no less than 100% of the Fair
Market Value per Share on the date of grant.

                    (3)  Notwithstanding the foregoing, Incentive Stock Options
may be granted with a per Share exercise price of less than 100% of the Fair
Market Value per Share on the date of grant pursuant to a merger or other
corporate transaction.

               (ii) The exercise price for the Shares to be issued pursuant to
an already granted Option may not be changed without the consent of the
Company's stockholders. This shall include, without limitation, a repricing of
the Option as well as an Exchange Program.

               (iii) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator will fix the period within which the Option may be
exercised and will determine any conditions that must be satisfied before the
Option may be exercised.

          (c)  Form of Consideration. The Administrator will determine the
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator will
determine the acceptable form of consideration at the time of grant. Such
consideration to the extent permitted by Applicable Laws may consist entirely
of:

               (i)  cash;

               (ii) check;

               (iii) promissory note;

               (iv) other Shares which meet the conditions established by the
Administrator to avoid adverse accounting consequences (as determined by the
Administrator);

               (v)  consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan;

               (vi) a reduction in the amount of any Company liability to the
Participant, including any liability attributable to the Participant's
participation in any Company-sponsored deferred compensation program or
arrangement;

               (vii) any combination of the foregoing methods of payment; or

               (viii) such other consideration and method of payment for the
issuance of Shares to the extent permitted by Applicable Laws.

          (d)  Exercise of Option.

               (i)  Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder will be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Award Agreement. An Option may not be exercised for a fraction of a
Share.

                                                                             -9-
<PAGE>

               An Option will be deemed exercised when the Company receives: (x)
written or electronic notice of exercise (in accordance with the Award
Agreement) from the person entitled to exercise the Option, and (y) full payment
for the Shares with respect to which the Option is exercised. Full payment may
consist of any consideration and method of payment authorized by the
Administrator and permitted by the Award Agreement and the Plan. Shares issued
upon exercise of an Option will be issued in the name of the Participant or, if
requested by the Participant, in the name of the Participant and his or her
spouse. Until the Shares are issued (as evidenced by the appropriate entry on
the books of the Company or of a duly authorized transfer agent of the Company),
no right to vote or receive dividends or any other rights as a stockholder will
exist with respect to the Awarded Stock, notwithstanding the exercise of the
Option. The Company will issue (or cause to be issued) such Shares promptly
after the Option is exercised. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are
issued, except as provided in Section 15 of the Plan.

          Exercising an Option in any manner will decrease the number of Shares
thereafter available, both for purposes of the Plan and for sale under the
Option, by the number of Shares as to which the Option is exercised.

          (ii) Termination of Relationship as a Service Provider. If a
Participant ceases to be a Service Provider, other than upon the Participant's
death or Disability, the Participant may exercise his or her Option within such
period of time as is specified in the Award Agreement to the extent that the
Option is vested on the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Award Agreement). In
the absence of a specified time in the Award Agreement, the Option will remain
exercisable for three (3) months following the Participant's termination. Unless
otherwise provided by the Administrator, if on the date of termination the
Participant is not vested as to his or her entire Option, the Shares covered by
the unvested portion of the Option will revert to the Plan. If after termination
the Participant does not exercise his or her Option within the time specified by
the Administrator, the Option will terminate, and the Shares covered by such
Option will revert to the Plan.

          (iii) Disability of Participant. If a Participant ceases to be a
Service Provider as a result of the Participant's Disability, the Participant
may exercise his or her Option within such period of time as is specified in the
Award Agreement to the extent the Option is vested on the date of termination
(but in no event later than the expiration of the term of such Option as set
forth in the Award Agreement). In the absence of a specified time in the Award
Agreement, the Option will remain exercisable for twelve (12) months following
the Participant's termination. Unless otherwise provided by the Administrator,
if on the date of termination the Participant is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option will
revert to the Plan. If after termination the Participant does not exercise his
or her Option within the time specified herein, the Option will terminate, and
the Shares covered by such Option will revert to the Plan.

          (iv) Death of Participant. If a Participant dies while a Service
Provider, the Option may be exercised following the Participant's death within
such period of time as is specified in the Award Agreement to the extent that
the Option is vested on the date of death (but in no event may the option be
exercised later than the expiration of the term of such Option as set forth in
the Award Agreement), by the Participant's designated beneficiary, provided such
beneficiary has been

                                                                            -10-
<PAGE>

designated prior to Participant's death in a form acceptable to the
Administrator. If no such beneficiary has been designated by the Participant,
then such Option may be exercised by the personal representative of the
Participant's estate or by the person(s) to whom the Option is transferred
pursuant to the Participant's will or in accordance with the laws of descent and
distribution. In the absence of a specified time in the Award Agreement, the
Option will remain exercisable for twelve (12) months following Participant's
death. Unless otherwise provided by the Administrator, if at the time of death
Participant is not vested as to his or her entire Option, the Shares covered by
the unvested portion of the Option will immediately revert to the Plan. If the
Option is not so exercised within the time specified herein, the Option will
terminate, and the Shares covered by such Option will revert to the Plan.

          (e)  Buyout Provisions. The Administrator may at any time offer to buy
out for a payment in cash or Shares an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Participant at the time that such offer is made.

     8.   Restricted Stock.

          (a)  Grant of Restricted Stock. Subject to the terms and provisions of
the Plan, the Administrator, at any time and from time to time, may grant Shares
of Restricted Stock to Service Providers in such amounts as the Administrator,
in its sole discretion, will determine.

          (b)  Restricted Stock Agreement. Each Award of Restricted Stock will
be evidenced by an Award Agreement that will specify the Period of Restriction,
the number of Shares granted, and such other terms and conditions as the
Administrator, in its sole discretion, will determine. Unless the Administrator
determines otherwise, Shares of Restricted Stock will be held by the Company as
escrow agent until the restrictions on such Shares have lapsed.

          (c)  Transferability. Except as provided in this Section 8, Shares of
Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise
alienated or hypothecated until the end of the applicable Period of Restriction.

          (d)  Other Restrictions. The Administrator, in its sole discretion,
may impose such other restrictions on Shares of Restricted Stock as it may deem
advisable or appropriate.

          (e)  Removal of Restrictions. Except as otherwise provided in this
Section 8, Shares of Restricted Stock covered by each Restricted Stock grant
made under the Plan will be released from escrow as soon as practicable after
the last day of the Period of Restriction. The Administrator, in its discretion,
may accelerate the time at which any restrictions will lapse or be removed.

          (f)  Voting Rights. During the Period of Restriction, Service
Providers holding Shares of Restricted Stock granted hereunder may exercise full
voting rights with respect to those Shares, unless the Administrator determines
otherwise.

          (g)  Dividends and Other Distributions. During the Period of
Restriction, Service Providers holding Shares of Restricted Stock will be
entitled to receive all dividends and other distributions paid with respect to
such Shares unless otherwise provided in the Award Agreement. If any such
dividends or distributions are paid in Shares, the Shares will be subject to the
same

                                                                            -11-
<PAGE>

restrictions on transferability and forfeitability as the Shares of Restricted
Stock with respect to which they were paid.

          (h)  Return of Restricted Stock to Company. On the date set forth in
the Award Agreement, the Restricted Stock for which restrictions have not lapsed
will revert to the Company and again will become available for grant under the
Plan.

     9.   Stock Appreciation Rights.

          (a)  Grant of SARs. Subject to the terms and conditions of the Plan, a
SAR may be granted to Service Providers at any time and from time to time as
will be determined by the Administrator, in its sole discretion. The
Administrator may grant Affiliated SARs, Freestanding SARs, Tandem SARs, or any
combination thereof.

          (b)  Number of Shares. The Administrator will have complete discretion
to determine the number of SARs granted to any Service Provider, subject to the
limits set forth in Section 6 of the Plan.

          (c)  Exercise Price and Other Terms. The Administrator, subject to the
provisions of the Plan, will have complete discretion to determine the terms and
conditions of SARs granted under the Plan. However, the exercise price of Tandem
or Affiliated SARs will equal the exercise price of the related Option. The
exercise price for the Shares to be issued pursuant to an already granted SAR
may not be changed without the consent of the Company's stockholders. This shall
include, without limitation, a repricing of the SAR as well as an Exchange
Program.

          (d)  Exercise of Tandem SARs. Tandem SARs may be exercised for all or
part of the Shares subject to the related Option upon the surrender of the right
to exercise the equivalent portion of the related Option. A Tandem SAR may be
exercised only with respect to the Shares for which its related Option is then
exercisable. With respect to a Tandem SAR granted in connection with an
Incentive Stock Option: (a) the Tandem SAR will expire no later than the
expiration of the underlying Incentive Stock Option; (b) the value of the payout
with respect to the Tandem SAR will be for no more than one hundred percent
(100%) of the difference between the exercise price of the underlying Incentive
Stock Option and the Fair Market Value of the Shares subject to the underlying
Incentive Stock Option at the time the Tandem SAR is exercised; and (c) the
Tandem SAR will be exercisable only when the Fair Market Value of the Shares
subject to the Incentive Stock Option exceeds the Exercise Price of the
Incentive Stock Option.

          (e)  Exercise of Affiliated SARs. An Affiliated SAR will be deemed to
be exercised upon the exercise of the related Option. The deemed exercise of an
Affiliated SAR will not necessitate a reduction in the number of Shares subject
to the related Option.

          (f)  Exercise of Freestanding SARs. Freestanding SARs will be
exercisable on such terms and conditions as the Administrator, in its sole
discretion, will determine.

          (g)  SAR Agreement. Each SAR grant will be evidenced by an Award
Agreement that will specify the exercise price, the term of the SAR, the
conditions of exercise, and such other terms and conditions as the
Administrator, in its sole discretion, will determine.

                                                                            -12-
<PAGE>

          (h)  Expiration of SARs. An SAR granted under the Plan will expire
upon the date determined by the Administrator, in its sole discretion, and set
forth in the Award Agreement. Notwithstanding the foregoing, the rules of
Sections 7(d)(ii), 7(d)(iii) and 7(d)(iv) also will apply to SARs.

               (i)  Payment of SAR Amount. Upon exercise of an SAR, a
Participant will be entitled to receive payment from the Company in an amount
determined by multiplying:

                    (i)  The difference between the Fair Market Value of a Share
on the date of exercise over the exercise price; times

                    (ii) The number of Shares with respect to which the SAR is
exercised.

          At the discretion of the Administrator, the payment upon SAR exercise
may be in cash, in Shares of equivalent value, or in some combination thereof.

          (j)  Buyout Provisions. The Administrator may at any time offer to buy
out for a payment in cash or Shares a Stock Appreciation Right previously
granted based on such terms and conditions as the Administrator shall establish
and communicate to the Participant at the time that such offer is made.

     10.  Performance Units and Performance Shares.

          (a)  Grant of Performance Units/Shares. Subject to the terms and
conditions of the Plan, Performance Units and Performance Shares may be granted
to Service Providers at any time and from time to time, as will be determined by
the Administrator, in its sole discretion. The Administrator will have complete
discretion in determining the number of Performance Units and Performance Shares
granted to each Participant.

          (b)  Value of Performance Units/Shares. Each Performance Unit will
have an initial value that is established by the Administrator on or before the
date of grant. Each Performance Share will have an initial value equal to the
Fair Market Value of a Share on the date of grant.

          (c)  Performance Objectives and Other Terms. The Administrator will
set performance objectives in its discretion which, depending on the extent to
which they are met, will determine the number or value of Performance
Units/Shares that will be paid out to the Service Providers. The time period
during which the performance objectives must be met will be called the
"Performance Period." Each Award of Performance Units/Shares will be evidenced
by an Award Agreement that will specify the Performance Period, and such other
terms and conditions as the Administrator, in its sole discretion, will
determine. The Administrator may set performance objectives based upon the
achievement of Company-wide, divisional, or individual goals, applicable federal
or state securities laws, or any other basis determined by the Administrator in
its discretion.

          (d)  Earning of Performance Units/Shares. After the applicable
Performance Period has ended, the holder of Performance Units/Shares will be
entitled to receive a payout of the number of Performance Units/Shares earned by
the Participant over the Performance Period, to be determined as a function of
the extent to which the corresponding performance objectives have been

                                                                            -13-

achieved. After the grant of a Performance Unit/Share, the Administrator, in its
sole discretion, may reduce or waive any performance objectives for such
Performance Unit/Share.

          (e)  Form and Timing of Payment of Performance Units/Shares. Payment
of earned Performance Units/Shares will be made as soon as practicable after the
expiration of the applicable Performance Period. The Administrator, in its sole
discretion, may pay earned Performance Units/Shares in the form of cash, in
Shares (which have an aggregate Fair Market Value equal to the value of the
earned Performance Units/Shares at the close of the applicable Performance
Period) or in a combination thereof.

          (f)  Cancellation of Performance Units/Shares. On the date set forth
in the Award Agreement, all unearned or unvested Performance Units/Shares will
be forfeited to the Company, and again will be available for grant under the
Plan.

     11.  Deferred Stock Units. Deferred Stock Units shall consist of a
Restricted Stock, Performance Share or Performance Unit Award that the
Administrator, in its sole discretion permits to be paid out in installments or
on a deferred basis, in accordance with rules and procedures established by the
Administrator.

     12.  Formula Option Grants to Outside Directors.

     All grants of Options to Outside Directors pursuant to this Section 12 will
be automatic and nondiscretionary and will be made in accordance with the
following provisions:

          (a)  Type of Option. All Options granted pursuant to this Section 12
will be Nonstatutory Stock Options and, except as otherwise provided herein,
will be subject to the other terms and conditions of the Plan.

          (b)  No Discretion. No person will have any discretion to select which
Outside Directors will be granted Options under this Section 12 or to determine
the number of Shares to be covered by such Options (except as provided in
Section 12(g) and Section 15 of the Plan).

          (c)  First Option. Each person who first becomes an Outside Director
following the Registration Date automatically will be granted an Option to
purchase 25,000 Shares (the "First Option") on the date on which such person
first becomes an Outside Director, whether through election by the stockholders
of the Company or appointment by the Board to fill a vacancy; provided, however,
that an Inside Director who ceases to be an Inside Director but who remains a
Director will not receive a First Option.

          (d)  Subsequent Option. Each Outside Director automatically will be
granted an Option to purchase 6,000 Shares (a "Subsequent Option") on the date
of each annual meeting of the stockholders of the Company beginning in 2005,
provide he or she is then an Outside Director, and if as of such date, he or she
will have served on the Board for at least the preceding six (6) months.

          (e)  Terms. The terms of each Option granted pursuant to this Section
12 will be as follows:

               (i)  The term of the Option will be ten (10) years.

                                                                            -14-
<PAGE>

               (ii) The exercise price per Share will be 100% of the Fair Market
Value per Share on the date of grant of the Option. In the event that the date
of grant of the Option is not a trading day, the exercise price per Share shall
be the Fair Market Value on the next trading day immediately following the date
of grant of the Option.

               (iii) The Option shall be exercisable only while the Outside
Director remains a Director of the Company, except as set forth in this Section
12 and Section 15 of the Plan.

               (iv) Subject to Section 15 of the Plan, the First Option will
vest and become exercisable as to 1/3rd of the Shares subject to the First
Option on each anniversary of its date of grant, provided that the Participant
continues to serve as a Director on such dates;

               (v)  Subject to Section 15 of the Plan, the Subsequent Option
will vest and become exercisable as to 100% of the Shares subject to the
Subsequent Option on the first anniversary of its date of grant, provided that
the Participant continues to serve as a Director on such dates.

          (f)  Exercise of Options. An Option granted pursuant to this Section
12 will expire upon the date determined by the Administrator, in its sole
discretion, and set forth in the Award Agreement. Notwithstanding the foregoing,
the rules of Sections 7(d)(ii), 7(d)(iii) and 7(d)(iv) also will apply to such
Option. To the extent that the Participant was not entitled to exercise an
Option on the date of termination, or if he or she does not exercise such Option
(to the extent otherwise so entitled) within the time specified herein, the
Option shall terminate.

          (g)  Amendment. The Administrator in its discretion may change the
number of Shares subject to the First Options and Subsequent Options.

     13.  Leaves of Absence. Unless the Administrator provides otherwise,
vesting of Awards granted hereunder will be suspended during any unpaid leave of
absence and will resume on the date the Participant returns to work on a regular
schedule as determined by the Company; provided, however, that no vesting credit
will be awarded for the time vesting has been suspended during such leave of
absence. A Service Provider will not cease to be an Employee in the case of (i)
any leave of absence approved by the Company or (ii) transfers between locations
of the Company or between the Company, its Parent, or any Subsidiary. For
purposes of Incentive Stock Options, no such leave may exceed ninety (90) days,
unless reemployment upon expiration of such leave is guaranteed by statute or
contract. If reemployment upon expiration of a leave of absence approved by the
Company is not so guaranteed, then three months following the 91st day of such
leave any Incentive Stock Option held by the Participant will cease to be
treated as an Incentive Stock Option and will be treated for tax purposes as a
Nonstatutory Stock Option.

     14.  Non-Transferability of Awards. Unless determined otherwise by the
Administrator, an Award may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Participant, only by the Participant. If the Administrator makes an Award
transferable, such Award will contain such additional terms and conditions as
the Administrator deems appropriate.

                                                                            -15-
<PAGE>

     15.  Adjustments; Dissolution or Liquidation; Merger or Change in Control.

          (a)  Adjustments. Subject to any required action by the stockholders
of the Company, the number of Shares covered by each outstanding Award, the
number of Shares which have been authorized for issuance under the Plan but as
to which no Awards have yet been granted or which have been returned to the Plan
upon cancellation or expiration of an Award, the number of Shares that may be
granted pursuant to the automatic grant provisions of Section 12 of the Plan and
the number of Shares as well as the price per share of Common Stock covered by
each such outstanding Award and the 162(m) annual share issuance limits under
Section 6(c) of the Plan shall be proportionately adjusted for any increase or
decrease in the number of issued Shares resulting from a stock split, reverse
stock split, stock dividend, combination or reclassification of the Common
Stock, or any other increase or decrease in the number of issued Shares effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. 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 an Award.

          (b)  Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator will notify each
Participant as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for a Participant
to have the right to exercise his or her Option or SAR until ten (10) days prior
to such transaction as to all of the Awarded Stock covered thereby, including
Shares as to which the Award would not otherwise be exercisable. In addition,
the Administrator may provide that any Company repurchase option or forfeiture
rights applicable to any Award shall lapse 100%, and that any Award vesting
shall accelerate 100%, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent it has not been
previously exercised (with respect to Options and SARs) or vested (with respect
to other Awards), an Award will terminate immediately prior to the consummation
of such proposed action.

          (c)  Merger or Change in Control.

               (i)  Stock Options and SARS. In the event of a merger or Change
in Control, each outstanding Option and SAR shall be assumed or an equivalent
option or SAR substituted by the successor corporation or a Parent or Subsidiary
of the successor corporation. With respect to Options granted to an Outside
Director pursuant to Section 12 of the Plan that are assumed or substituted for,
if following such assumption or substitution the Participant's status as a
Director or a director of the successor corporation, as applicable, is
terminated other than upon a voluntary resignation by the Participant, then the
Participant shall fully vest in and have the right to exercise such Options as
to all of the Awarded Stock, including Shares as to which it would not otherwise
be vested or exercisable. In the event that the successor corporation refuses to
assume or substitute for the Option or SAR, the Participant shall fully vest in
and have the right to exercise the Option or SAR as to all of the Awarded Stock,
including Shares as to which it would not otherwise be vested or exercisable. If
an Option or SAR becomes fully vested and exercisable in lieu of assumption or
substitution in the event of a merger or Change in Control, the Administrator
shall notify the

                                                                            -16-
<PAGE>

Participant in writing or electronically that the Option or SAR shall be fully
vested and exercisable for a period of fifteen (15) days from the date of such
notice, and the Option or SAR shall terminate upon the expiration of such
period. For the purposes of this paragraph, the Option or SAR shall be
considered assumed if, following the merger or Change in Control, the option or
stock appreciation right confers the right to purchase or receive, for each
Share of Awarded Stock subject to the Option or SAR immediately prior to the
merger or Change in Control, the consideration (whether stock, cash, or other
securities or property) received in the merger or Change in Control by holders
of Common Stock for each Share held on the effective date of the transaction
(and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or Change
in Control is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option or
SAR, for each Share of Awarded Stock subject to the Option or SAR, to be solely
common stock of the successor corporation or its Parent equal in fair market
value to the per share consideration received by holders of Common Stock in the
merger or Change in Control. Notwithstanding anything herein to the contrary, an
Award that vests, is earned or paid-out upon the satisfaction of one or more
performance goals will not be considered assumed if the Company or its successor
modifies any of such performance goals without the Participant's consent;
provided, however, a modification to such performance goals only to reflect the
successor corporation's post-merger or post-Change in Control corporate
structure will not be deemed to invalidate an otherwise valid Award assumption.

               (ii) Restricted Stock, Performance Shares, Performance Units and
Deferred Stock Units. In the event of a merger or Change in Control, each
outstanding Restricted Stock, Performance Share, Performance Unit and Deferred
Stock Unit award shall be assumed or an equivalent Restricted Stock, Performance
Share, Performance Unit and Deferred Stock Unit award substituted by the
successor corporation or a Parent or Subsidiary of the successor corporation. In
the event that the successor corporation refuses to assume or substitute for the
Restricted Stock, Performance Share, Performance Unit or Deferred Stock Unit
award, the Participant shall fully vest in the Restricted Stock, Performance
Share, Performance Unit or Deferred Stock Unit including as to Shares (or with
respect to Performance Units, the cash equivalent thereof) which would not
otherwise be vested. For the purposes of this paragraph, a Restricted Stock,
Performance Share, Performance Unit and Deferred Stock Unit award shall be
considered assumed if, following the merger or Change in Control, the award
confers the right to purchase or receive, for each Share (or with respect to
Performance Units, the cash equivalent thereof) subject to the Award immediately
prior to the merger or Change in Control, the consideration (whether stock,
cash, or other securities or property) received in the merger or Change in
Control by holders of Common Stock for each Share held on the effective date of
the transaction (and if holders were offered a choice of consideration, the type
of consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the merger or Change
in Control is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received, for each Share and each unit/right
to acquire a Share subject to the Award, to be solely common stock of the
successor corporation or its Parent equal in fair market value to the per share
consideration received by holders of Common Stock in the merger or Change in
Control. Notwithstanding anything herein to the contrary, an Award that vests,
is earned or paid-out upon the satisfaction of one or more performance goals
will not be considered assumed if the Company or its successor modifies any of
such

                                                                            -17-
<PAGE>

performance goals without the Participant's consent; provided, however, a
modification to such performance goals only to reflect the successor
corporation's post-merger or post-Change in Control corporate structure will not
be deemed to invalidate an otherwise valid Award assumption.

     16.  Date of Grant. The date of grant of an Award will be, for all
purposes, the date on which the Administrator makes the determination granting
such Award, or such other later date as is determined by the Administrator.
Notice of the determination will be provided to each Participant within a
reasonable time after the date of such grant.

     17.  Term of Plan. Subject to Section 21 of the Plan, the Plan will become
effective upon its adoption by the Board. It will continue in effect for a term
of ten (10) years unless terminated earlier under Section 18 of the Plan.

     18.  Amendment and Termination of the Plan.

          (a)  Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

          (b)  Stockholder Approval. The Company will obtain stockholder
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

          (c)  Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan will impair the rights of any Participant,
unless mutually agreed otherwise between the Participant and the Administrator,
which agreement must be in writing and signed by the Participant and the
Company. Termination of the Plan will not affect the Administrator's ability to
exercise the powers granted to it hereunder with respect to Awards granted under
the Plan prior to the date of such termination.

     19.  Conditions Upon Issuance of Shares.

          (a)  Legal Compliance. Shares will not be issued pursuant to the
exercise of an Award unless the exercise of such Award and the issuance and
delivery of such Shares (or with respect to Performance Units, the cash
equivalent thereof) will comply with Applicable Laws and will be further subject
to the approval of counsel for the Company with respect to such compliance.

          (b)  Investment Representations. As a condition to the exercise or
receipt of an Award, the Company may require the person exercising or receiving
such Award to represent and warrant at the time of any such exercise or receipt
that the Shares are being purchased only for investment and without any present
intention to sell or distribute such Shares if, in the opinion of counsel for
the Company, such a representation is required.

     20.  Inability to Obtain Authority. The inability of the Company to obtain
authority from any regulatory body having jurisdiction, which authority is
deemed by the Company's counsel to be necessary to the lawful issuance and sale
of any Shares hereunder (or with respect to Performance Units, the cash
equivalent thereof), will relieve the Company of any liability in respect of the
failure to issue or sell such Shares (or with respect to Performance Units, the
cash equivalent thereof) as to which such requisite authority will not have been
obtained.

                                                                            -18-
<PAGE>

     21.  Stockholder Approval. The Plan will be subject to approval by the
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval will be obtained in the manner and to the
degree required under Applicable Laws.

                                                                            -19-

II.   AGREEMENT

      A.    Grant of Option.

            The Plan Administrator of the Company hereby grants to the Optionee
named in the Notice of Grant attached as Part I of this Agreement (the
"Optionee") an option (the "Option") to purchase the number of Shares, as set
forth in the Notice of Grant, at the exercise price per share set forth in the
Notice of Grant (the "Exercise Price"), subject to the terms and conditions of
the Plan, which is incorporated herein by reference. Subject to Section 18(c) of
the Plan, in the event of a conflict between the terms and conditions of the
Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

            If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code. However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

      B.    Exercise of Option.

            (a)   Right to Exercise. This Option is exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

            (b)   Method of Exercise. This Option is exercisable by delivery of
an exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to [TITLE] of the Company. The Exercise Notice
shall be accompanied by payment of the aggregate Exercise Price as to all
Exercised Shares. This Option shall be deemed to be exercised upon receipt by
the Company of such fully executed Exercise Notice accompanied by such aggregate
Exercise Price.

            No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

                                                                             -2-
<PAGE>
      C.    Method of Payment.

            Payment of the aggregate Exercise Price shall be by any of the
following, or a combination thereof, at the election of the Optionee:

            1.    cash; or

            2.    check; or

            3.    consideration received by the Company under a formal cashless
exercise program implemented by the Company in connection with the Plan; or

            4.    to the extent permitted by the Administrator, surrender of
other Shares which (i) in the case of Shares acquired either directly or
indirectly from the Company, have been owned by the Optionee for more than six
(6) months on the date of surrender, and (ii) have a Fair Market Value on the
date of surrender equal to the aggregate Exercise Price of the Exercised Shares.

      D.    Non-Transferability of Option.

            This Option may not be transferred in any manner otherwise than by
will or by the laws of descent or distribution and may be exercised during the
lifetime of Optionee only by the Optionee. The terms of the Plan and this Option
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

      E.    Term of Option.

            This Option may be exercised only within the term set out in the
Notice of Grant, and may be exercised during such term only in accordance with
the Plan and the terms of this Option Agreement.

      F.    Tax Obligations.

            (a)   Withholding Taxes. Optionee agrees to make appropriate
arrangements with the Company (or the Parent or Subsidiary employing or
retaining Optionee) for the satisfaction of all Federal, state, local and
foreign income and employment tax withholding requirements applicable to the
Option exercise. Optionee acknowledges and agrees that the Company may refuse to
honor the exercise and refuse to deliver Shares if such withholding amounts are
not delivered at the time of exercise.

            (b)   Notice of Disqualifying Disposition of ISO Shares. If the
Option granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the

                                                                             -3-
<PAGE>
date one year after the date of exercise, the Optionee shall immediately notify
the Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

      G.    Entire Agreement; Governing Law.

            The Plan is incorporated herein by reference. The Plan and this
Option Agreement constitute the entire agreement of the parties with respect to
the subject matter hereof and supersede in their entirety all prior undertakings
and agreements of the Company and Optionee with respect to the subject matter
hereof, and may not be modified adversely to the Optionee's interest except by
means of a writing signed by the Company and Optionee. This agreement is
governed by the internal substantive laws, but not the choice of law rules, of
California.

      H.    NO GUARANTEE OF CONTINUED SERVICE.

            OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT
TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE
PROVIDER AT THE WILL OF THE COMPANY (AND NOT THROUGH THE ACT OF BEING HIRED,
BEING GRANTED AN OPTION OR PURCHASING SHARES HEREUNDER). OPTIONEE FURTHER
ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED
HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS
OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING
PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE WITH OPTIONEE'S RIGHT
OR THE COMPANY'S RIGHT TO TERMINATE OPTIONEE'S RELATIONSHIP AS A SERVICE
PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE.

                                                                             -4-
<PAGE>
            By your signature and the signature of the Company's representative
below, you and the Company agree that this Option is granted under and governed
by the terms and conditions of the Plan and this Option Agreement. Optionee has
reviewed the Plan and this Option Agreement in their entirety, has had an
opportunity to obtain the advice of counsel prior to executing this Option
