set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, hereby amend the Second Amended and Restated Registration
Rights Agreement and agree as follows:

     1.   Section 1.4 of Article 1 is hereby deleted and replaced with the
following:

     1.4  "Holders" shall mean and include each of Bechtel, Sandler, Highland,
the Other Investors, Oak, the Series C Investors, the Series D Investor and The
Procter & Gamble Company and any person or entity that shall have executed this
Agreement and whose name appears on the Schedule of Registration Rights Holders
attached hereto as Exhibit A or who shall, pursuant to Section 11.3 hereof,
become a party hereto, and any permitted transferee under Article 9 hereof which
holds Registrable Securities; except that, for purposes of Section 2.1 of
Article 1 and Article 3, Holders shall not include the parties listed on
Schedule 3 hereto.

     2.   The definition of "Registrable Securities" set forth in Section 1.9 of
Article 1 is hereby deleted and replaced with the following:

          1.9  "Registrable Securities" means any and all shares of Common
     Stock: (i) issued or issuable upon conversion of the Series A Stock, the
     Series B

                                       2
<PAGE>   3

     Stock, the Series C Stock and the Series D Stock; (ii) issued or issuable
     upon the exercise of the Procter & Gamble Warrant; (iii) issued or issuable
     with respect to the Series A Stock, the Series B Stock, the Series C Stock,
     the Series D Stock or Procter & Gamble Warrant upon any stock split, stock
     dividend, combination, recapitalization, reclassification, merger,
     consolidation or other similar event; and (iv) otherwise held or acquired
     by any of Bechtel, Sandler, Highland, Oak, or the Series C Investors,
     Series D Investor, or the Other Investors excluding in all cases, however,
     Registrable Securities sold by a Holder to the public or pursuant to Rule
     144 promulgated under the Securities Act (or any similar or analogous rule
     promulgated under the Securities Act). For purposes of this Agreement, a
     person will be deemed to be a Holder of Registrable Securities whenever
     such person has the right to acquire directly or indirectly such
     Registrable Securities (upon conversion or exercise in connection with a
     transfer of securities or otherwise, but disregarding any restrictions or
     limitations upon the exercise of such right), whether or not such
     acquisition has actually been effected.

     2.   Article 1 is hereby amended to include the following definition:

          1.16 "Series D Investor" shall mean the purchasers of Series D
     Convertible Preferred Stock, par value $0.001 per share, of the Company
     (the "Series D Stock") set forth on Schedule 2 attached hereto.

     3.   The first sentence of Section 2.2 of Article 2 is hereby deleted and
replaced with the following:

               Request by Series C Investors and Series D Investor for
     Registration. Beginning on the earlier of (i) the date which is 180 days
     after the effective date of Series C Qualified Public Offering or (ii) the
     date which is after November 17, 2001, upon the request of one or more of
     the Series C Investors and/or Series D Investor who own in the aggregate
     not less than forty percent of the Series C Stock and Series D Stock,
     combined (the "Series C and D Initiating Holders"), such Series C and D
     Initiating Holders may request registration in accordance with this Article
     2; provided that, the Series C and D Initiating Holders may not request
     registration pursuant to this Article 2 prior to the effective date of
     Series C Qualified Public Offering unless such requested registration is
     for a public offering of shares reasonably anticipated to have an aggregate
     offering price to the public of at least $5,000,000. In the event the
     Company shall receive from the Series C and D Initiating Holders a written
     request that the Company effect any such registration, qualification or
     compliance with respect to Registrable Securities, the Company will:

     4.   Section 2.2(c) of Article 2 is hereby deleted and replaced with the
following:

                                       3
<PAGE>   4

          (c)  Subject to the foregoing clauses (i) through (v), the Company
     shall file a registration statement covering the Registrable Securities so
     requested to be registered as soon as practicable after receipt of the
     request of the Series C and D Initiating Holders and provide notice to the
     other Holders as required by Section 2.2(a); provided, however, that if the
     Company shall furnish to such Holders a certificate signed by the Chairman
     or Chief Executive Officer of the Company stating that in the good faith
     judgment of the Board of Directors of the Company, it would be detrimental
     to the Company and its stockholders for such registration statement to be
     filed, the Company shall have the right to defer such filing for a period
     of not more than 180 days after receipt of the request of such Series C and
     D Initiating Holders; provided, further, that the Company shall not be
     permitted to exercise such deferral right under this Section 2.2(c) or
     Section 4.1(c) hereof more than once in any 365-day period.

     5.   Section 2.3(a) of Article 2 is hereby deleted and replaced with the
following:

          (a)  With respect to registrations initiated pursuant to Section 2.1
     herein, the distribution of the Registrable Securities covered by the
     request of the Holders shall be effected by means of the method of
     distribution selected by the Holders holding a majority of the Registrable
     Securities covered by such registration. With respect to registrations
     initiated pursuant to Section 2.2 herein, the distribution of Registrable
     Securities covered by such request shall be effected by means of the method
     selection by the holders of a majority of the Series C Investors and Series
     D Investor, combined, holding Registrable Securities. If such distribution
     is effected by means of an underwriting, the right of any Holder to
     registration pursuant to this Article 2 shall be conditioned upon such
     Holder's participation in such underwriting and the inclusion of such
     Holder's Registrable Securities in the underwriting to the extent provided
     herein.

     6.   Article 10 is hereby amended to include the following:

          10.3 In connection with the grant of registration rights to the
     holders of the Series D Stock and to the Procter & Gamble Company pursuant
     to this Agreement, each of Sandler, Bechtel, Highland, Oak, the Series C
     Investors and the Other Investors agree and consent to waive the provisions
     of Article 10 relating to limitations on registration rights granted to
     other securities holders set forth in the Second Amended and Restated
     Registration Rights Agreement.

     7.   Section 11.4 of Article 11 is hereby deleted and replaced with the
     following:

                                       4
<PAGE>   5

          11.4 Entire Agreement. This Agreement constitutes the full and entire
     understanding and agreement between the parties with regard to the subject
     matter hereof. Subject to Sections 11.11, 11.12 and 11.13 herein, any
     provision of this Agreement may be amended, waived or modified, and this
     Agreement may be terminated, if, but only if, such amendment, waiver or
     modification or termination is in writing and is signed by the holders of a
     majority of the Series A Stock, Series B Stock and Series C Stock and
     Series D Stock, combined, provided, however, that no amendment, waiver,
     modification or termination may treat any holder that does not consent
     thereto differently than a holder that does consent thereto; whenever any
     provision of this Agreement requires action or approval by the holders of a
     specified number of Series A Stock, Series B Stock or Series C Stock and
     Series D Stock, combined, such action or approval may be evidenced by a
     written consent executed by the requisite holders of Series A Stock, Series
     B Stock or Series C Stock and Series D Stock, combined, without any
     requirement of a meeting or prior notice to the other holders of such
     shares.
