         holders of at least 60% of the Series B Preferred, Series B-1

         "Certificate"), the Common Stockholders and Investors shall vote their
         shares of capital stock of Company for a Board of Directors consisting
         of nine (9) directors. For so long as the outstanding Shares of Series
         A Preferred constitute five percent (5%) or more of the Company's
         outstanding capital stock (on a fully diluted basis), the Series A
         Investors, voting separately as a class, shall have the right to elect

         with respect thereto) by a vote of a majority of the then outstanding

         Investors shall designate one person as nominee for director and such
         Series A Investors agree to designate and vote their Shares in favor of
         such nominee. For so long as the outstanding Shares of Series B
         Preferred and Series B-1 Preferred, collectively, constitute five
         percent (5%) or more of the Company's outstanding capital stock (on a
         fully diluted basis), the Series B Investors and the Series B-1
         Investors, voting together and separately as a class, shall have the

         connection therewith, the Series B Investors and Series B-1 Investors
         shall designate one person as nominee for director and such Series B
         Investors and Series B-1 Investors agree to designate and vote their
         Shares in favor of such nominee. The initial Series B Director shall be
         designated by STF Institutional Partners II, L.P. For so long as the
         outstanding Shares of Series C Preferred constitute five percent (5%)
         or more of the Company's outstanding capital stock (on a fully diluted
         basis), the Series C Investors, voting separately as a class, shall
         have the right to elect two (2) directors (the "Series C Directors")
         (and to fill any vacancies with respect thereto) by a vote of a
         majority of the then outstanding shares of Series C Preferred. One (1)
         Series C Director initially shall be designated by Investors holding a
         majority of the Shares of Series C Preferred and the other Series C
         Director shall be Paul Reaves. Each of the Series C Investors shall
         vote their Series C Shares in favor of such designee and such nominee.
         For so long as the outstanding Shares of Series D Preferred constitute
         two and one-half percent (2.5%) or more of the Company's outstanding
         capital stock (on a fully diluted basis), the Series D Investors,
         voting separately as a class, shall have the right to elect one (1)
         director (the "Series D Director") (and to fill any vacancies with
         respect thereto) by a vote of a majority of the then outstanding shares
         of Series D Preferred. The Series D Director initially shall be John
         Thompson. In addition, each party shall vote such party's shares of
         capital stock of the Company to elect (i) Jett as a director while Jett
         remains an employee of Company and (ii) Mark Gehring as a director
         until the earlier of (A) May 30,

         to elect to acquire such number of Preemptive Shares (of the
         same class or series, and having the same relative rights and
         preferences, as the securities offered in the Subject
         Issuance) which

                                  5
<PAGE>

         shall be determined when such Preemptive Investor's
         percentage ownership of the outstanding Common Stock (which
         shall be determined as if all outstanding Preferred Stock had
         been converted into Common Stock) immediately preceding the
         Subject Issuance is multiplied by the aggregate number of
         Preemptive Shares referred to in the Company's notice
         ("Initial Preemptive Right"). If any transaction specified by
         the Company in any such notice shall be consummated after the
         date that is six (6) months after the date of such notice,
         the Company shall again comply with the provisions of this
         Section 9(b) with respect to such transaction, and all
         Preemptive Investors shall again have preemptive rights
         hereunder with respect thereto, regardless of whether any
         such Preemptive Investor had previously exercised or failed
         to exercise such rights. Any purchase of securities pursuant
         to the exercise of preemptive rights hereunder with respect
         to a Subject Issuance that has not been consummated at the
         time the Company's notice is given shall be consummated
         simultaneously with, and shall be conditioned upon,

         Investor's address as set forth on Schedule 7 attached
         hereto, or at such other address as such Series E Investor
         shall have furnished to the other parties hereto in writing."

         (O)      The last sentence of Section 15(e) is hereby deleted in its
entirety and replaced with the following:

         purchasers of Shares of its Preferred Stock pursuant to
         Section 2.1 of the Series E Preferred Stock Purchase
         Agreement, dated as of June 25, 2003, as parties to this
         Agreement as and in the manner set forth in such Section 2.1,

may be executed in two or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same
instrument. The facsimile signature of any party to this Second Amendment for
purposes of execution or otherwise is to be considered as an original signature,
and the document transmitted is to be considered to have the same binding effect
as an original signature on an original document. At the request of any party,
any facsimile or telecopy document is to be re-executed in original form by the
parties who executed the facsimile or telecopy document. No party may raise the
use of a facsimile machine or telecopier or the fact that any signature was
transmitted through the use of a facsimile or telecopier machine as a defense to
the enforcement of this Second Amendment or any notice required thereof.
