                               NEW AIR CORPORATION
                       RESTRICTED STOCK PURCHASE AGREEMENT

            AGREEMENT made as of this 2nd day of November 1998, by and between
New Air Corporation, a Delaware corporation (the "Corporation"), and Neeleman
Holdings, LC (the "Purchaser").

            All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

      A. PURCHASE OF SHARES

            1. PURCHASE. Purchaser hereby purchases 1,851 shares of Common Stock
(the "Purchased Shares") at the purchase price of $25.96 per share (the
"Purchase Price").

            2. PAYMENT. Concurrently with the delivery of this Agreement to the
Corporation, Purchaser shall pay the Purchase Price for the Purchased Shares in
cash or cash equivalent and shall deliver a duly-executed blank Assignment
Separate from Certificate (in the form attached hereto as Exhibit I) with
respect to the Purchased Shares.

            3. STOCKHOLDER RIGHTS. Until such time as the Corporation exercises
the Repurchase Right or the First Refusal Right, Purchaser (or any successor in
interest) shall have all stockholder rights (including voting, dividend and
liquidation rights) with respect to the Purchased Shares, including the
Purchased Shares held in escrow hereunder, subject, however, to the transfer
restrictions of Articles B and C.

            4. DELIVERY OF CERTIFICATES. The certificates representing any
Purchased Shares which are subject to the Repurchase Right shall be held in
escrow in accordance with the provisions of this Agreement.

      B. SECURITIES LAW COMPLIANCE

            1. RESTRICTED SECURITIES. The Purchased Shares have not been
registered under the 1933 Act and are being issued to Purchaser in reliance upon
the exemption from such registration provided by Section 4(2) of the 1933 Act.
Purchaser hereby confirms that Purchaser has been informed that the Purchased
Shares are restricted securities under the 1933 Act and may not be resold or
transferred unless the Purchased Shares are first registered under the Federal
securities laws or unless an exemption from such registration is available.
Accordingly, Purchaser hereby acknowledges that Purchaser is prepared to hold
the Purchased Shares for an indefinite period and that Purchaser is aware that
SEC Rule 144 issued under the 1933 Act which exempts certain resales of
unrestricted securities is not presently available to exempt the resale of the
Purchased Shares from the registration requirements of the 1933 Act.

            2. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser hereby
represents and warrants that:

            (i) The Purchased Shares are being acquired for investment purposes
      only for the Purchaser's own account, and not as a nominee or agent, and
      not with a view to the resale or distribution of all or any part of the
      Purchased Shares. Purchaser is prepared to hold the Purchased Shares for
      an indefinite period and has no present intention of selling, granting any
      participating interest in, or otherwise distributing any of the Purchased
      Shares. Purchaser does not have any contract, undertaking, agreement or
      arrangement with any person to sell, transfer or grant a participating
      interest in, any of the Purchased Shares.

            (ii) Purchaser has a preexisting personal or business relationship
      with either the Corporation or certain Board members or officers of the
      Corporation which is of a nature and duration sufficient to make Purchaser
      aware of the character, business acumen and general business and financial
      circumstances of the Corporation and/or such Board members or officers. In
      addition, Purchaser has been furnished with, and has had access to, such
      information concerning the Corporation's business, management and
      financial condition as he or she considers necessary or appropriate for
      deciding whether to invest in the Purchased Shares, and Purchaser has had
      an opportunity to ask questions and receive answers from the Corporation
      regarding the terms and conditions of the issuance of the Purchased
      Shares.

            (iii) Purchaser is able to fend for him or herself in the
      transactions contemplated by this Agreement, can bear the economic risk of
      investment in the Purchased Shares and has such knowledge and experience
      in financial or business matters to be capable of evaluating the merits
      and risks of the investment in the Purchased Shares. Purchaser is fully
      aware of: (i) the speculative nature of the investment in the Purchased
      Shares; (ii) the financial risk involved; (iii) the lack of liquidity for
      the Purchased Shares and (iv) the transfer restrictions and repurchase
      rights applicable to the Purchased Shares.

            3. DISPOSITION OF PURCHASED SHARES. Purchaser shall make no
disposition of the Purchased Shares (other than a Permitted Transfer) unless and
until there is compliance with all of the following requirements:

            (i) Purchaser shall have provided the Corporation with a written
      summary of the terms and conditions of the proposed disposition.

            (ii) Purchaser shall have complied with all requirements of this
      Agreement applicable to the disposition of the Purchased Shares.

            (iii) Purchaser shall have provided the Corporation with written
      assurances, in form and substance satisfactory to the Corporation, that
      (a) the proposed disposition does not require registration of the
      Purchased Shares under

                                       2
<Page>

      the 1933 Act or (b) all appropriate action necessary for compliance with
      the registration requirements of the 1933 Act or any exemption from
      registration available under the 1933 Act (including Rule 144) has been
      taken.

            The Corporation shall NOT be required (i) to transfer on its books
any Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement OR (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

            4. RESTRICTIVE LEGENDS. The stock certificates for the Purchased
Shares shall be endorsed with one or more of the following restrictive legends
and any legend required to be placed thereon by the applicable blue sky laws of
any state:

                  "The shares represented by this certificate have not been
      registered under the Securities Act of 1933. The shares may not be sold or
      offered for sale in the absence of (a) an effective registration statement
      for the shares under such Act, (b) a "no action" letter of the Securities
      and Exchange Commission with respect to such sale or offer or (c)
      satisfactory assurances to the Corporation that registration under such
      Act is not required with respect to such sale or offer."

                  "The shares represented by this certificate are subject to
      certain repurchase rights and rights of first refusal granted to the
      Corporation and accordingly may not be sold, assigned, transferred,
      encumbered, or in any manner disposed of except in conformity with the
      terms of a written agreement dated November ___, 1998, between the
      Corporation and the registered holder of the shares (or the predecessor in
      interest to the shares). A copy of such agreement is maintained at the
      Corporation's principal corporate offices."

      C. TRANSFER RESTRICTIONS

            1. RESTRICTION ON TRANSFER. Except for any Permitted Transfer,
Purchaser shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right. In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right or the Market Stand-Off.

            2. TRANSFEREE OBLIGATIONS. Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Purchaser.

                                       3
<Page>

            3. MARKET STAND-OFF.

                  (a) In connection with the Company's initial public offering
of its equity securities pursuant to an effective registration statement filed
under the 1933 Act and in connection with any other underwritten public offering
by the Corporation of its equity securities pursuant to an effective
registration statement filed under the 1933 Act during the period two years
after the effective date of such initial public offering, Owner shall not sell,
make any short sale of, loan, hypothecate, pledge, grant any option for the
purchase of, or otherwise dispose or transfer for value or otherwise agree to
engage in any of the foregoing transactions with respect to, any Purchased
Shares without the prior written consent of the Corporation or its underwriters.
Such restriction (the "Market Stand-Off") shall be in effect for such period of
time from and after the effective date of the final prospectus for the offering
as may be requested by the Corporation or such underwriters. In no event,
however, shall any single period exceed one hundred eighty (180) days from the
effective date of any such public offering.

                  (b) Owner shall be subject to the Market Stand-Off PROVIDED
AND ONLY IF the officers and directors of the Corporation are also subject to
similar restrictions.

                  (c) Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

                  (d) In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

      D. REPURCHASE RIGHT

            1. GRANT. The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Purchaser ceases for any reason to remain in Service, to
repurchase at the Purchase Price any or all of the Purchased Shares in which
Purchaser is not, at the time of his or her cessation of Service, vested in
accordance with the provisions of the Vesting Schedule set forth in Paragraph
D.3 or the special vesting acceleration provisions of Paragraph D.5 (such shares
to be hereinafter referred to as the "Unvested Shares").

            2. EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period. The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice. The certificates representing the Unvested Shares
to be repurchased shall be delivered to the Corporation on or before the close
of business on the date specified for the repurchase. Concurrently with the
receipt of such stock certificates, the Corporation shall pay to Owner, in cash
or cash equivalents

                                       4
<Page>

(including the cancellation of any purchase-money indebtedness), an amount equal
to the Purchase Price previously paid for the Unvested Shares which are to be
repurchased from Owner.

            3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Purchaser vests in accordance with the following Vesting Schedule:

                  Purchaser shall vest in the Purchased Shares, and the
      Repurchase Right shall concurrently lapse with respect to those Purchased
      Shares, in a series of five (5) successive equal annual installments upon
      Purchaser's completion of each year of Service over the five (5) year
      period measured from November 2, 1998.

            All Purchased Shares as to which the Repurchase Right lapses shall,
however, remain subject to (i) the First Refusal Right and (ii) the Market
Stand-Off.

            4. RECAPITALIZATION. Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right and any
escrow requirements hereunder, but only to the extent the Purchased Shares are
at the time covered by such right or escrow requirements. Appropriate
adjustments to reflect such distribution shall be made to the number and/or
class of Purchased Shares subject to this Agreement and to the price per share
to be paid upon the exercise of the Repurchase Right in order to reflect the
effect of any such Recapitalization upon the Corporation's capital structure;
PROVIDED, however, that the aggregate purchase price shall remain the same.

            5. SPECIAL ACCELERATION EVENTS.

                  (a) The Repurchase Right shall automatically terminate in its
entirety, and all the Purchased Shares shall vest in full, immediately prior to
the consummation of any Corporate Transaction.

                  (b) The Repurchase Right shall automatically terminate in its
entirety, and all Purchased Shares shall vest in full, immediately in the event
the Purchaser's employment with the Corporation or its affiliates is terminated
by the Corporation without Cause.

      E. RIGHT OF FIRST REFUSAL

            1. GRANT. The Corporation is hereby granted the right of first
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Purchaser has vested in accordance
with the provisions of Article D. For purposes of this

                                       5
<Page>

Article E, the term "transfer" shall include any sale, assignment, pledge,
encumbrance or other disposition of the Purchased Shares intended to be made by
Owner, but shall not include any Permitted Transfer.

            2. NOTICE OF INTENDED DISPOSITION. In the event any Owner of
Purchased Shares in which Purchaser has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

            3. EXERCISE OF THE FIRST REFUSAL RIGHT. The Corporation shall, for a
period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents. Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period. If such right is exercised with respect to
all the Target Shares, then the Corporation shall effect the repurchase of such
shares, including payment of the purchase price, not more than five (5) business
days after delivery of the Exercise Notice; and at such time the certificates
representing the Target Shares shall be delivered to the Corporation.

            Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property. If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an appraiser
of recognized standing selected by Owner and the Corporation or, if they cannot
agree on an appraiser within twenty (20) days after the Corporation's receipt of
the Disposition Notice, each shall select an appraiser of recognized standing
and the two (2) appraisers shall designate a third appraiser of recognized
standing, whose appraisal shall be determinative of such value. The cost of such
appraisal shall be shared equally by Owner and the Corporation. The closing
shall then be held on the LATER of (i) the fifth (5th) business day following
delivery of the Exercise Notice or (ii) the fifth (5th) business day after such
valuation shall have been made.

            4. NON-EXERCISE OF THE FIRST REFUSAL RIGHT. In the event the
Exercise Notice is not given to Owner prior to the expiration of the twenty-five
(25)-day exercise period, Owner shall have a period of thirty (30) days
thereafter in which to sell or otherwise dispose of the Target Shares to the
third-party offeror identified in the Disposition Notice upon terms (including
the purchase price) no more favorable to such third-party offeror than those
specified in the Disposition Notice; PROVIDED, however, that any such sale or
disposition must not be effected in contravention of the provisions of Articles
B and C. The third-party offeror shall acquire the Target Shares subject to the
First Refusal Right and the provisions of Article B and Paragraph C.3. In the
event Owner does not effect such sale or disposition of the Target Shares

                                       6
<Page>

within the specified thirty (30)-day period, the First Refusal Right shall
continue to be applicable to any subsequent disposition of the Target Shares by
Owner until such right lapses.

            5. PARTIAL EXERCISE OF THE FIRST REFUSAL RIGHT. In the event the
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:

                        (i) sale or other disposition of all the Target Shares
      to the third-party offeror identified in the Disposition Notice, but in
      full compliance with the requirements of Paragraph E.4, as if the
      Corporation did not exercise the First Refusal Right; or

                        (ii) sale to the Corporation of the portion of the
      Target Shares which the Corporation has elected to purchase, such sale to
      be effected in substantial conformity with the provisions of Paragraph
      E.3. The First Refusal Right shall continue to be applicable to any
      subsequent disposition of the remaining Target Shares until such right
      lapses.

            Owner's failure to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

            6. RECAPITALIZATION. Any new, substituted or additional securities
or other property which is by reason of any Recapitalization distributed with
respect to the Purchased Shares shall be immediately subject to the First
Refusal Right, but only to the extent the Purchased Shares are at the time
covered by such right.

            7. LAPSE. The First Refusal Right shall lapse upon the EARLIEST to
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination made by the
Board that a public market exists for the outstanding shares of Common Stock,
(iii) a firm commitment underwritten public offering, pursuant to an effective
registration statement under the 1933 Act, covering the offer and sale of the
Common Stock or (iv) a Corporate Transaction. However, the Market Stand-Off
shall continue to remain in full force and effect following the lapse of the
First Refusal Right.

      F. ESCROW.

            1. DEPOSIT. Upon issuance, the certificates for the Purchased Shares
which are subject to the Repurchase Right shall be deposited in escrow with the
Corporation to be held in accordance with the provisions of this Article F. Each
deposited certificate shall be accompanied by a duly-executed Assignment
Separate from Certificate in the form of Exhibit I. The deposited certificates,
together with any other assets or securities from time to time deposited with
the Corporation pursuant to the requirements of this Agreement, shall remain in
escrow until such

                                       7
<Page>

time or times as the certificates (or other assets and securities) are to be
released or otherwise surrendered for cancellation in accordance with Paragraph
F.3. Upon delivery of the certificates (or other assets and securities) to the
Corporation, Owner shall be issued a receipt acknowledging the number of
Purchased Shares (or other assets and securities) delivered in escrow.

            2. RECAPITALIZATION. Any new, substituted or additional securities
or other property which is by reason of any Recapitalization distributed with
respect to the Purchased Shares shall be immediately delivered to the
Corporation to be held in escrow under this Article F, but only to the extent
the Purchased Shares are at the time subject to the escrow requirements
hereunder. However, all regular cash dividends on the Purchased Shares (or other
securities at the time held in escrow) shall be paid directly to Owner and shall
not be held in escrow.

            3. RELEASE/SURRENDER. The Purchased Shares, together with any other
assets or securities held in escrow hereunder, shall be subject to the following
terms relating to their release from escrow or their surrender to the
Corporation for repurchase and cancellation:

            (i) Should the Corporation elect to exercise the Repurchase Right
      with respect to any Unvested Shares, then the escrowed certificates for
      those Unvested Shares (together with any other assets or securities
      attributable thereto) shall be surrendered to the Corporation concurrently
      with the payment to Owner of an amount equal to the aggregate Exercise
      Price for such Unvested Shares, and Owner shall cease to have any further
      rights or claims with respect to such Unvested Shares (or other assets or
      securities attributable thereto).

            (ii) Should the Corporation elect to exercise the First Refusal
      Right with respect to any Target Shares held at the time in escrow
      hereunder, then the escrowed certificates for those Target Shares
      (together with any other assets or securities attributable thereto) shall
      be surrendered to the Corporation concurrently with the payment of the
      Paragraph E.3 purchase price for such Target Shares to Owner, and Owner
      shall cease to have any further rights or claims with respect to such
      Target Shares (or other assets or securities attributable thereto).

            (iii) Should the Corporation elect NOT to exercise the Repurchase
      Right with respect to any Unvested Shares or the First Refusal Right with
      respect to any Target Shares held at the time in escrow hereunder, then
      the escrowed certificates for those shares (together with any other assets
      or securities attributable thereto) shall be immediately released to
      Owner.

            (iv) As the Purchased Shares (or any other assets or securities
      attributable thereto) vest in accordance with the Vesting Schedule, the
      certificates for those vested shares (as well as all other vested assets
      and securities) shall be released from escrow upon Owner's request, but
      not more frequently than once every six (6) months.

                                       8
<Page>

            (v) All Purchased Shares which vest (and any other vested assets and
      securities attributable thereto) shall be released within thirty (30) days
      after the EARLIER to occur of (a) Optionee's cessation of Service or (b)
      the lapse of the First Refusal Right.

            (vi) All Purchased Shares (or other assets or securities) released
      from escrow shall nevertheless remain subject to (a) the First Refusal
      Right, to the extent such right has not otherwise lapsed and (b) the
      Market Stand-Off, until such restriction terminates.

      G. SPECIAL TAX ELECTION

            1. SECTION 83(b) ELECTION . Under Code Section 83, the excess of the
Fair Market Value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date. For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Purchaser may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions. Such election must be filed
with the Internal Revenue Service within thirty (30) days after the date of this
Agreement. Even if the Fair Market Value of the Purchased Shares on the date of
this Agreement equals the Purchase Price paid (and thus no tax is payable), the
election must be made to avoid adverse tax consequences in the future. THE FORM
FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. PURCHASER UNDERSTANDS
THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-DAY PERIOD
WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE RESTRICTIONS
LAPSE.

            2. FILING RESPONSIBILITY. PURCHASER ACKNOWLEDGES THAT IT IS
PURCHASER'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY
ELECTION UNDER CODE SECTION 83(b), EVEN IF PURCHASER REQUESTS THE CORPORATION OR
ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.

      H. GENERAL PROVISIONS

            1. ASSIGNMENT. The Corporation may assign the Repurchase Right
and/or the First Refusal Right to any person or entity selected by the Board,
including (without limitation) one or more stockholders of the Corporation.

            2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement
shall confer upon Purchaser any right to continue in Service for any period of
specific duration or interfere with or otherwise restrict in any way the rights
of the Corporation (or any Parent or Subsidiary employing or retaining
Purchaser) or of Purchaser, which rights are hereby expressly

                                       9
<Page>

reserved by each, to terminate Purchaser's Service at any time for any reason,
with or without cause. If Purchaser and the Corporation have entered into an
agreement with respect to Purchaser's rights to continue in Service, that
agreement is set forth in a separate employment or consulting agreement with
Purchaser.

            3. NOTICES. Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

            4. NO WAIVER. The failure of the Corporation in any instance to
exercise the Repurchase Right or the First Refusal Right shall not constitute a
waiver of any other repurchase rights and/or rights of first refusal that may
subsequently arise under the provisions of this Agreement or any other agreement
between the Corporation and Purchaser. No waiver of any breach or condition of
this Agreement shall be deemed to be a waiver of any other or subsequent breach
or condition, whether of like or different nature.

            5. CANCELLATION OF SHARES. If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from

                               NEW AIR CORPORATION
                       RESTRICTED STOCK PURCHASE AGREEMENT

            AGREEMENT made as of this 2nd day of November 1998, by and between
New Air Corporation, a Delaware corporation (the "Corporation"), and John Owen
(the "Purchaser").

            All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

      A.    PURCHASE OF SHARES

            1. PURCHASE. Purchaser hereby purchases 1,333 shares of Common Stock
(the "Purchased Shares") at the purchase price of $25.96 per share (the
"Purchase Price").

            2. PAYMENT. Concurrently with the delivery of this Agreement to the
Corporation, Purchaser shall pay the Purchase Price for the Purchased Shares in
cash or cash equivalent and shall deliver a duly-executed blank Assignment
Separate from Certificate (in the form attached hereto as Exhibit I) with
respect to the Purchased Shares.

the Repurchase Right or the First Refusal Right, Purchaser (or any successor in
interest) shall have all stockholder rights (including voting, dividend and
liquidation rights) with respect to the Purchased Shares, including the
Purchased Shares held in escrow hereunder, subject, however, to the transfer
restrictions of Articles B and C.

            4. DELIVERY OF CERTIFICATES. The certificates representing any
Purchased Shares which are subject to the Repurchase Right shall be held in
escrow in accordance with the provisions of this Agreement.

      B.    SECURITIES LAW COMPLIANCE

            1. RESTRICTED SECURITIES. The Purchased Shares have not been
registered under the 1933 Act and are being issued to Purchaser in reliance upon
the exemption from such registration provided by Section 4(2) of the 1933 Act.
Purchaser hereby confirms that Purchaser has been informed that the Purchased
Shares are restricted securities under the 1933 Act and may not be resold or
transferred unless the Purchased Shares are first registered under the Federal
securities laws or unless an exemption from such registration is available.
Accordingly, Purchaser hereby acknowledges that Purchaser is prepared to hold
the Purchased Shares for an indefinite period and that Purchaser is aware that
SEC Rule 144 issued under the 1933 Act which exempts certain resales of
unrestricted securities is not presently available to exempt the resale of the
Purchased Shares from the registration requirements of the 1933 Act.

            2. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser hereby
represents and warrants that:

<Page>

            (i) The Purchased Shares are being acquired for investment purposes
      only for the Purchaser's own account, and not as a nominee or agent, and
      not with a view to the resale or distribution of all or any part of the
      Purchased Shares. Purchaser is prepared to hold the Purchased Shares for
      an indefinite period and has no present intention of selling, granting any
      participating interest in, or otherwise distributing any of the Purchased
      Shares. Purchaser does not have any contract, undertaking, agreement or
      arrangement with any person to sell, transfer or grant a participating
      interest in, any of the Purchased Shares.

            (ii) Purchaser has a preexisting personal or business relationship
      with either the Corporation or certain Board members or officers of the
      Corporation which is of a nature and duration sufficient to make Purchaser
      aware of the character, business acumen and general business and financial
      circumstances of the Corporation and/or such Board members or officers. In
      addition, Purchaser has been furnished with, and has had access to, such
      information concerning the Corporation's business, management and
      financial condition as he or she considers necessary or appropriate for
      deciding whether to invest in the Purchased Shares, and Purchaser has had
      an opportunity to ask questions and receive answers from the Corporation
      regarding the terms and conditions of the issuance of the Purchased
      Shares.

            (iii) Purchaser is able to fend for him or herself in the
      transactions contemplated by this Agreement, can bear the economic risk of
      investment in the Purchased Shares and has such knowledge and experience
      in financial or business matters to be capable of evaluating the merits
      and risks of the investment in the Purchased Shares. Purchaser is fully
      aware of: (i) the speculative nature of the investment in the Purchased
      Shares; (ii) the financial risk involved; (iii) the lack of liquidity for
      the Purchased Shares and (iv) the transfer restrictions and repurchase
      rights applicable to the Purchased Shares.

            3. DISPOSITION OF PURCHASED SHARES. Purchaser shall make no
disposition of the Purchased Shares (other than a Permitted Transfer) unless and
until there is compliance with all of the following requirements:

            (i) Purchaser shall have provided the Corporation with a written
      summary of the terms and conditions of the proposed disposition.

            (ii) Purchaser shall have complied with all requirements of this
      Agreement applicable to the disposition of the Purchased Shares.

            (iii) Purchaser shall have provided the Corporation with written
      assurances, in form and substance satisfactory to the Corporation, that
      (a) the proposed disposition does not require registration of the
      Purchased Shares under the 1933 Act or (b) all appropriate action
      necessary for compliance with the registration requirements of the 1933
      Act or any exemption from registration available under the 1933 Act
      (including Rule 144) has been taken.

                                       2
<Page>

            The Corporation shall NOT be required (i) to transfer on its books
any Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement OR (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

            4. RESTRICTIVE LEGENDS. The stock certificates for the Purchased
Shares shall be endorsed with one or more of the following restrictive legends
and any legend required to be placed thereon by the applicable blue sky laws of
any state:

                  "The shares represented by this certificate have not been
      registered under the Securities Act of 1933. The shares may not be sold or
      offered for sale in the absence of (a) an effective registration statement
      for the shares under such Act, (b) a "no action" letter of the Securities
      and Exchange Commission with respect to such sale or offer or (c)
      satisfactory assurances to the Corporation that registration under such
      Act is not required with respect to such sale or offer."

                  "The shares represented by this certificate are subject to
      certain repurchase rights and rights of first refusal granted to the
      Corporation and accordingly may not be sold, assigned, transferred,
      encumbered, or in any manner disposed of except in conformity with the
      terms of a written agreement dated November ___, 1998, between the
      Corporation and the registered holder of the shares (or the predecessor in
      interest to the shares). A copy of such agreement is maintained at the
      Corporation's principal corporate offices."

      C.    TRANSFER RESTRICTIONS

            1. RESTRICTION ON TRANSFER. Except for any Permitted Transfer,
Purchaser shall not transfer, assign, encumber or otherwise dispose of any of
the Purchased Shares which are subject to the Repurchase Right. In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right or the Market Stand-Off.

            2. TRANSFEREE OBLIGATIONS. Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Purchaser.

            3. MARKET STAND-OFF.

                  (a) In connection with the Company's initial public offering
of its equity securities pursuant to an effective registration statement filed
under the 1933 Act and in connection with any other underwritten public offering
by the Corporation of its equity securities

                                       3
<Page>

pursuant to an effective registration statement filed under the 1933 Act during
the period two years after the effective date of such initial public offering,
Owner shall not sell, make any short sale of, loan, hypothecate, pledge, grant
any option for the purchase of, or otherwise dispose or transfer for value or
otherwise agree to engage in any of the foregoing transactions with respect to,
any Purchased Shares without the prior written consent of the Corporation or its
underwriters. Such restriction (the "Market Stand-Off") shall be in effect for
such period of time from and after the effective date of the final prospectus
for the offering as may be requested by the Corporation or such underwriters. In
no event, however, shall any single period exceed one hundred eighty (180) days
from the effective date of any such public offering.

                  (b) Owner shall be subject to the Market Stand-Off PROVIDED
AND ONLY IF the officers and directors of the Corporation are also subject to
similar restrictions.

                  (c) Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

                  (d) In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

      D.    REPURCHASE RIGHT

            1. GRANT. The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Purchaser ceases for any reason to remain in Service, to
repurchase at the Purchase Price any or all of the Purchased Shares in which
Purchaser is not, at the time of his or her cessation of Service, vested in
accordance with the provisions of the Vesting Schedule set forth in Paragraph
D.3 or the special vesting acceleration provisions of Paragraph D.5 (such shares
to be hereinafter referred to as the "Unvested Shares").

            2. EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period. The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice. The certificates representing the Unvested Shares
to be repurchased shall be delivered to the Corporation on or before the close
of business on the date specified for the repurchase. Concurrently with the
receipt of such stock certificates, the Corporation shall pay to Owner, in cash
or cash equivalents (including the cancellation of any purchase-money
indebtedness), an amount equal to the Purchase Price previously paid for the
Unvested Shares which are to be repurchased from Owner.

            3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2. In addition, the Repurchase Right shall terminate
and cease to be exercisable with respect to any and all Purchased Shares in
which Purchaser vests in accordance with the following Vesting Schedule:

                  Purchaser shall vest in the Purchased Shares, and the
      Repurchase Right shall concurrently lapse with respect to those Purchased
      Shares, in a series of five (5) successive equal annual installments upon
      Purchaser's completion of each year of Service over the five (5) year
      period measured from November 2, 1998.

            All Purchased Shares as to which the Repurchase Right lapses shall,
however, remain subject to (i) the First Refusal Right and (ii) the Market
Stand-Off.

            4. RECAPITALIZATION. Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right and any
escrow requirements hereunder, but only to the extent the Purchased Shares are
at the time covered by such right or escrow requirements. Appropriate
adjustments to reflect such distribution shall be made to the number and/or
class of Purchased Shares subject to this Agreement and to the price per share
to be paid upon the exercise of the Repurchase Right in order to reflect the
effect of any such Recapitalization upon the Corporation's capital structure;
provided, however, that the aggregate purchase price shall remain the same.

            5. SPECIAL ACCELERATION EVENTS.

                  (a) The Repurchase Right shall automatically terminate in its
entirety, and all the Purchased Shares shall vest in full, immediately prior to
the consummation of any Corporate Transaction.

                  (b) The Repurchase Right shall automatically terminate in its
entirety, and all Purchased Shares shall vest in full, immediately in the event
the Purchaser's employment with the Corporation or its affiliates is terminated
by the Corporation without Cause.

      E.    RIGHT OF FIRST REFUSAL

            1. GRANT. The Corporation is hereby granted the right of first
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Purchaser has vested in accordance
with the provisions of Article D. For purposes of this Article E, the term
"transfer" shall include any sale, assignment, pledge, encumbrance or other
disposition of the Purchased Shares intended to be made by Owner, but shall not
include any Permitted Transfer.

                                       5
<Page>

            2. NOTICE OF INTENDED DISPOSITION. In the event any Owner of
Purchased Shares in which Purchaser has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

            3. EXERCISE OF THE FIRST REFUSAL RIGHT. The Corporation shall, for a
period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents. Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period. If such right is exercised with respect to
all the Target Shares, then the Corporation shall effect the repurchase of such
shares, including payment of the purchase price, not more than five (5) business
days after delivery of the Exercise Notice; and at such time the certificates
representing the Target Shares shall be delivered to the Corporation.

            Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property. If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an appraiser
of recognized standing selected by Owner and the Corporation or, if they cannot
agree on an appraiser within twenty (20) days after the Corporation's receipt of
the Disposition Notice, each shall select an appraiser of recognized standing
and the two (2) appraisers shall designate a third appraiser of recognized
standing, whose appraisal shall be determinative of such value. The cost of such
appraisal shall be shared equally by Owner and the Corporation. The closing
shall then be held on the LATER of (i) the fifth (5th) business day following
delivery of the Exercise Notice or (ii) the fifth (5th) business day after such
valuation shall have been made.

            4. NON-EXERCISE OF THE FIRST REFUSAL RIGHT. In the event the
Exercise Notice is not given to Owner prior to the expiration of the twenty-five
(25)-day exercise period, Owner shall have a period of thirty (30) days
thereafter in which to sell or otherwise dispose of the Target Shares to the
third-party offeror identified in the Disposition Notice upon terms (including
the purchase price) no more favorable to such third-party offeror than those
specified in the Disposition Notice; PROVIDED, however, that any such sale or
disposition must not be effected in contravention of the provisions of Articles
B and C. The third-party offeror shall acquire the Target Shares subject to the
First Refusal Right and the provisions of Article B and Paragraph C.3. In the
event Owner does not effect such sale or disposition of the Target Shares within
the specified thirty (30)-day period, the First Refusal Right shall continue to
be applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses.

                                       6
<Page>

            5. PARTIAL EXERCISE OF THE FIRST REFUSAL RIGHT. In the event the
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:

                  (i) sale or other disposition of all the Target Shares to the
      third-party offeror identified in the Disposition Notice, but in full
      compliance with the requirements of Paragraph E.4, as if the Corporation
      did not exercise the First Refusal Right; or

                  (ii) sale to the Corporation of the portion of the Target
      Shares which the Corporation has elected to purchase, such sale to be
      effected in substantial conformity with the provisions of Paragraph E.3.
      The First Refusal Right shall continue to be applicable to any subsequent
      disposition of the remaining Target Shares until such right lapses.

            Owner's failure to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

            6. RECAPITALIZATION. Any new, substituted or additional securities
or other property which is by reason of any Recapitalization distributed with
respect to the Purchased Shares shall be immediately subject to the First
Refusal Right, but only to the extent the Purchased Shares are at the time
covered by such right.

            7. LAPSE. The First Refusal Right shall lapse upon the EARLIEST to
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination made by the
Board that a public market exists for the outstanding shares of Common Stock,
(iii) a firm commitment underwritten public offering, pursuant to an effective
registration statement under the 1933 Act, covering the offer and sale of the
Common Stock or (iv) a Corporate Transaction. However, the Market Stand-Off
shall continue to remain in full force and effect following the lapse of the
First Refusal Right.

      F.    ESCROW.

            1. DEPOSIT. Upon issuance, the certificates for the Purchased Shares
which are subject to the Repurchase Right shall be deposited in escrow with the
Corporation to be held in accordance with the provisions of this Article F. Each
deposited certificate shall be accompanied by a duly-executed Assignment
Separate from Certificate in the form of Exhibit I. The deposited certificates,
together with any other assets or securities from time to time deposited with
the Corporation pursuant to the requirements of this Agreement, shall remain in
escrow until such time or times as the certificates (or other assets and
securities) are to be released or otherwise surrendered for cancellation in
accordance with Paragraph F.3. Upon delivery of the certificates (or other
assets and securities) to the Corporation, Owner shall be issued a receipt

                                       7
<Page>

acknowledging the number of Purchased Shares (or other assets and securities)
delivered in escrow.

            2. RECAPITALIZATION. Any new, substituted or additional securities
or other property which is by reason of any Recapitalization distributed with
respect to the Purchased Shares shall be immediately delivered to the
Corporation to be held in escrow under this Article F, but only to the extent
the Purchased Shares are at the time subject to the escrow requirements
hereunder. However, all regular cash dividends on the Purchased Shares (or other
securities at the time held in escrow) shall be paid directly to Owner and shall
not be held in escrow.

            3. RELEASE/SURRENDER. The Purchased Shares, together with any other
assets or securities held in escrow hereunder, shall be subject to the following
terms relating to their release from escrow or their surrender to the
Corporation for repurchase and cancellation:

            (i) Should the Corporation elect to exercise the Repurchase Right
      with respect to any Unvested Shares, then the escrowed certificates for
      those Unvested Shares (together with any other assets or securities
      attributable thereto) shall be surrendered to the Corporation concurrently
      with the payment to Owner of an amount equal to the aggregate Exercise
      Price for such Unvested Shares, and Owner shall cease to have any further
      rights or claims with respect to such Unvested Shares (or other assets or
      securities attributable thereto).

            (ii) Should the Corporation elect to exercise the First Refusal
      Right with respect to any Target Shares held at the time in escrow
      hereunder, then the escrowed certificates for those Target Shares
      (together with any other assets or securities attributable thereto) shall
      be surrendered to the Corporation concurrently with the payment of the
      Paragraph E.3 purchase price for such Target Shares to Owner, and Owner
      shall cease to have any further rights or claims with respect to such
      Target Shares (or other assets or securities attributable thereto).

            (iii) Should the Corporation elect NOT to exercise the Repurchase
      Right with respect to any Unvested Shares or the First Refusal Right with
      respect to any Target Shares held at the time in escrow hereunder, then
      the escrowed certificates for those shares (together with any other assets
      or securities attributable thereto) shall be immediately released to
      Owner.

            (iv) As the Purchased Shares (or any other assets or securities
      attributable thereto) vest in accordance with the Vesting Schedule, the
      certificates for those vested shares (as well as all other vested assets
      and securities) shall be released from escrow upon Owner's request, but
      not more frequently than once every six (6) months.

            (v) All Purchased Shares which vest (and any other vested assets and
      securities attributable thereto) shall be released within thirty (30) days
      after

                                       8
<Page>

      the EARLIER to occur of (a) Optionee's cessation of Service or (b) the
      lapse of the First Refusal Right.

            (vi) All Purchased Shares (or other assets or securities) released
      from escrow shall nevertheless remain subject to (a) the First Refusal
      Right, to the extent such right has not otherwise lapsed and (b) the
      Market Stand-Off, until such restriction terminates.

      G.    SPECIAL TAX ELECTION

            1. SECTION 83(b) ELECTION . Under Code Section 83, the excess of the
Fair Market Value of the Purchased Shares on the date any forfeiture
restrictions applicable to such shares lapse over the Purchase Price paid for
such shares will be reportable as ordinary income on the lapse date. For this
purpose, the term "forfeiture restrictions" includes the right of the
Corporation to repurchase the Purchased Shares pursuant to the Repurchase Right.
Purchaser may elect under Code Section 83(b) to be taxed at the time the
Purchased Shares are acquired, rather than when and as such Purchased Shares
cease to be subject to such forfeiture restrictions. Such election must be filed
with the Internal Revenue Service within thirty (30) days after the date of this
Agreement. Even if the Fair Market Value of the Purchased Shares on the date of
this Agreement equals the Purchase Price paid (and thus no tax is payable), the
election must be made to avoid adverse tax consequences in the future. THE FORM
FOR MAKING THIS ELECTION IS ATTACHED AS EXHIBIT II HERETO. PURCHASER UNDERSTANDS
THAT FAILURE TO MAKE THIS FILING WITHIN THE APPLICABLE THIRTY (30)-DAY PERIOD
WILL RESULT IN THE RECOGNITION OF ORDINARY INCOME AS THE FORFEITURE RESTRICTIONS
LAPSE.

            2. FILING RESPONSIBILITY. PURCHASER ACKNOWLEDGES THAT IT IS
PURCHASER'S SOLE RESPONSIBILITY, AND NOT THE CORPORATION'S, TO FILE A TIMELY
ELECTION UNDER CODE SECTION 83(b), EVEN IF PURCHASER REQUESTS THE CORPORATION OR
ITS REPRESENTATIVES TO MAKE THIS FILING ON HIS OR HER BEHALF.

      H.    GENERAL PROVISIONS

            1. ASSIGNMENT. The Corporation may assign the Repurchase Right
and/or the First Refusal Right to any person or entity selected by the Board,
including (without limitation) one or more stockholders of the Corporation.

            2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement
shall confer upon Purchaser any right to continue in Service for any period of
specific duration or interfere with or otherwise restrict in any way the rights
of the Corporation (or any Parent or Subsidiary employing or retaining
Purchaser) or of Purchaser, which rights are hereby expressly reserved by each,
to terminate Purchaser's Service at any time for any reason, with or without
cause. If Purchaser and the Corporation have entered into an agreement with
respect to

                                       9
<Page>

Purchaser's rights to continue in Service, that agreement is set forth in a
separate employment or consulting agreement with Purchaser.

            3. NOTICES. Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

            4. NO WAIVER. The failure of the Corporation in any instance to
exercise the Repurchase Right or the First Refusal Right shall not constitute a
waiver of any other repurchase rights and/or rights of first refusal that may
subsequently arise under the provisions of this Agreement or any other agreement
between the Corporation and Purchaser. No waiver of any breach or condition of
this Agreement shall be deemed to be a waiver of any other or subsequent breach
or condition, whether of like or different nature.

            5. CANCELLATION OF SHARES. If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

      I.    MISCELLANEOUS PROVISIONS

            1. GOVERNING LAW. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of Delaware without resort to that
State's conflict-of-laws rules.

            2. PURCHASER UNDERTAKING. Purchaser hereby agrees to take whatever
additional action and execute whatever additional documents the Corporation may
deem necessary or advisable in order to carry out or effect one or more of the
obligations or restrictions imposed on either Purchaser or the Purchased Shares
pursuant to the provisions of this Agreement.

            3. AGREEMENT IS ENTIRE CONTRACT. This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter
hereof.

            4. COUNTERPARTS. This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

            5. SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Purchaser, Purchaser's assigns and the legal
representatives, heirs and legatees of Purchaser's estate, whether or not any
such person shall have become a party to this Agreement and have agreed in
writing to join herein and be bound by the terms hereof.
